This study investigated the psychological risks of emotional demands and discrimination as well as the buffering roles of two types of job resources (job autonomy and job security) among immigrant microbusiness owners (MBOs). Data were derived from a cross-sectional survey of 550 Korean immigrant MBOs, aged 30 to 70, living in Toronto and its surrounding areas. Face-to-face interviews were conducted between March and November 2013. Results showed that emotional suppression and discrimination were positively associated with depressive symptoms. However, the direct effect of positive emotional demands was insignificant. For job resources, the beneficial effect of job security on depressive symptom was apparent, but the effect of job autonomy was trivial. Regarding the moderating effect, job security buffered the psychological harm of both emotional suppression and workplace discrimination. Although job autonomy buffered the link between discrimination and depressive symptoms, the buffering effect of job autonomy on the emotional suppression-depression link was insignificant. This study’s finding implies that emotional demands and workplace discrimination seem to be important factors in contributing to occupational psychological problems, but the psychological impact can differ according to the types of emotional demands and job resources among immigrant MBOs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=immigrant%20microbusiness%20owners" title="immigrant microbusiness owners">immigrant microbusiness owners</a>, <a href="https://publications.waset.org/abstracts/search?q=emotional%20demands" title=" emotional demands"> emotional demands</a>, <a href="https://publications.waset.org/abstracts/search?q=discrimination" title=" discrimination"> discrimination</a>, <a href="https://publications.waset.org/abstracts/search?q=job%20resources" title=" job resources"> job resources</a>, <a href="https://publications.waset.org/abstracts/search?q=depression" title=" depression"> depression</a> </p> <a href="https://publications.waset.org/abstracts/79255/the-psychological-effect-of-emotional-demands-and-discrimination-and-the-role-of-job-resources-among-asian-immigrant-microbusiness-owners" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79255.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">222</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">139</span> Clinical Impact of Delirium and Antipsychotic Therapy: 10-Year Experience from a Referral Coronary Care Unit</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Niyada%20Naksuk">Niyada Naksuk</a>, <a href="https://publications.waset.org/abstracts/search?q=Thoetchai%20Peeraphatdit"> Thoetchai Peeraphatdit</a>, <a href="https://publications.waset.org/abstracts/search?q=Vitaly%20Herasevich"> Vitaly Herasevich</a>, <a href="https://publications.waset.org/abstracts/search?q=Peter%20A.%20Brady"> Peter A.

Our aim was to examine the effect of delirium and antipsychotic therapy among CCU patients. Methods: Pre-study Confusion Assessment Method-Intensive Care Unit (CAM–ICU) criteria were implemented in screening consecutive patients admitted to Mayo Clinic, Rochester, the USA from 2004 through 2013. Death status was prospectively ascertained. Results: Of 11,079 study patients, the incidence of delirium was 8.3% (n=925). Delirium was associated with an increased risk of in-hospital mortality (adjusted OR 1.49; 95% CI, 1.08-2.08; P=.02) and one-year mortality among patients who survived from CCU admission (adjusted HR 1.46; 95% CI, 1.12-1.87; P=.005). A total of 792 doses of haloperidol (5 IQR [3-10] mg/day) or quetiapine (25 IQR [13-50] mg/day) were given to 244 patients with delirium. The clinical characteristics of patients with delirium who did and did not receive antipsychotic therapy were not different (baseline corrected QT [QTc] interval 460±61 ms vs. 457±58 ms, respectively; P = 0.57). In comparison to baseline, mean QTc intervals after the first and third doses of the antipsychotics were not significantly prolonged in haloperidol (448±56, 458±57, and 450±50 ms, respectively) or quetiapine groups (459±54, 467±68, and 462±46 ms, respectively) (P > 0.05 for all). Additionally, in-hospital mortality (adjusted OR 0.67; 95% CI, 0.42-1.04; P=.07), ventricular arrhythmia (adjusted OR 0.87; 95% CI, 0.17-3.62; P=.85) and one-year mortality among the hospital survivors (adjusted HR 0.86; 95% CI 0.62-1.17; P = 0.34) were not different in patients with delirium irrespective of whether or not they received antipsychotics. Conclusions: In patients admitted to the CCU, delirium was associated with an increase in both in-hospital and one-year mortality. Low doses of haloperidol and quetiapine appeared to be safe, without an increase in risk of sudden cardiac death, in-hospital mortality, or one-year mortality in carefully monitored patients. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=arrhythmias" title="arrhythmias">arrhythmias</a>, <a href="https://publications.waset.org/abstracts/search?q=haloperidol" title=" haloperidol"> haloperidol</a>, <a href="https://publications.waset.org/abstracts/search?q=mortality" title=" mortality"> mortality</a>, <a href="https://publications.waset.org/abstracts/search?q=qtc%20interval" title=" qtc interval"> qtc interval</a>, <a href="https://publications.waset.org/abstracts/search?q=quetiapine" title=" quetiapine"> quetiapine</a> </p> <a href="https://publications.waset.org/abstracts/30814/clinical-impact-of-delirium-and-antipsychotic-therapy-10-year-experience-from-a-referral-coronary-care-unit" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30814.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">372</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">138</span> Discursive Construction of Strike in the Media Coverage of Academic Staff Union of Universities vs Federal Government of Nigeria Industrial Conflict of 2013</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samuel%20Alaba%20Akinwotu">Samuel Alaba Akinwotu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Over the years, Nigeria’s educational system has greatly suffered from the menace of industrial conflict. The smooth running of the nation’s public educational institutions has been hampered by incessant strikes embarked upon by workers of these institutions. Even though industrial conflicts in Nigeria have enjoyed wide reportage in the media, there has been a dearth of critical examination of the language use that index the conflict’s discourse in the media. This study which is driven by a combination of Critical Discourse Analysis (CDA) and Conceptual Metaphor (CM) examines the discursive and ideological features of language indexing the industrial conflict between the Academic Staff Union of Universities (ASUU) and the Federal Government of Nigeria (FGN) in 2013. It aims to identify and assess the conceptual and cognitive motivations of the stances expressed by the parties and the public and the role of the media in the management and resolution of the conflict. For data, media reports and readers’ comments were purposively sampled from six print and online news sources (The Punch, This Day, Vanguard, The Nation, Osun Defender and AITonline) published between July and December 2013. The study provides further insight into industrial conflict and proves to be useful for the management and resolution of industrial conflicts especially in our public educational institutions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=industrial%20conflict" title="industrial conflict">industrial conflict</a>, <a href="https://publications.waset.org/abstracts/search?q=critical%20discourse%20analysis" title=" critical discourse analysis"> critical discourse analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=conceptual%20metaphor" title=" conceptual metaphor"> conceptual metaphor</a>, <a href="https://publications.waset.org/abstracts/search?q=federal%20government%20of%20Nigeria" title=" federal government of Nigeria"> federal government of Nigeria</a>, <a href="https://publications.waset.org/abstracts/search?q=academic%20staff%20union%20of%20universities" title=" academic staff union of universities"> academic staff union of universities</a> </p> <a href="https://publications.waset.org/abstracts/86799/discursive-construction-of-strike-in-the-media-coverage-of-academic-staff-union-of-universities-vs-federal-government-of-nigeria-industrial-conflict-of-2013" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/86799.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">142</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">137</span> Capnography in Hypoxic Pseudo-Pea May Correlate to the Amount of Required Intervention for Resuscitation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yiyuan%20David%20%20Hu">Yiyuan David Hu</a>, <a href="https://publications.waset.org/abstracts/search?q=Alex%20Lindqwister"> Alex Lindqwister</a>, <a href="https://publications.waset.org/abstracts/search?q=Samuel%20B.%20%20Klein"> Samuel B.

Paradis</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Pseudo-Pulseless Electrical Activity (p-PEA) is a lifeless form of profound cardiac shock characterized by measurable cardiac mechanical activity without clinically detectable pulses. Patients in pseudo-PEA carry different prognoses than those in true PEA and may require different therapies. End-tidal carbon dioxide (ET-CO2) has been studied in ventricular fibrillation and true PEA but in p-PEA. We utilized an hypoxic porcine model to characterize the performance of ET-CO2 in resuscitation from p-PEA. Hypothesis: Capnography correlates to the number of required interventions for resuscitation from p-PEA. Methods: Female swine (N = 14) under intravenous anesthesia were instrumented with aortic and right atrial micromanometer pressure. ECG and ET-CO2 were measured continuously. p-PEA was induced by ventilation with 6% oxygen in 94% nitrogen and was defined as a systolic aortic (Ao) pressure less than 40 mmHg. Pigs were grouped based on the interventions required to achieve ROSC: 100%O2, 100%O2 + CPR, 100%O2 + CPR + epinephrine. Results: End tidal CO2 reliably predicted O2 therapy vs CPR-based interventions needed for resuscitation (Figure 1). Pigs who would recover with 100%O2 only had a mean ET-CO2 slope of 0.039 ± 0.013 [ R2 = 0.68], those requiring oxygen + CPR had a slope of -0.15 ± 0.016 [R2 = 0.95], and those requiring oxygen + CPR + epinephrine had a slope of -0.12 ± 0.031 [R2 = 0.79]. Conclusions: In a porcine model of hypoxic p-PEA, measured ET-CO2 appears to be strongly correlated with the required interventions needed for ROSC. If confirmed clinically, these results indicate that ET-CO2 may be useful in guiding therapy in patients suffering p-PEA cardiac arrest. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pseudo-PEA" title="pseudo-PEA">pseudo-PEA</a>, <a href="https://publications.waset.org/abstracts/search?q=resuscitation" title=" resuscitation"> resuscitation</a>, <a href="https://publications.waset.org/abstracts/search?q=capnography" title=" capnography"> capnography</a>, <a href="https://publications.waset.org/abstracts/search?q=hypoxic%20pseudo-PEA" title=" hypoxic pseudo-PEA"> hypoxic pseudo-PEA</a> </p> <a href="https://publications.waset.org/abstracts/134315/capnography-in-hypoxic-pseudo-pea-may-correlate-to-the-amount-of-required-intervention-for-resuscitation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/134315.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">194</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">136</span> The Effects of Self-Efficacy on Challenge and Threat States</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nadine%20Sammy">Nadine Sammy</a>, <a href="https://publications.waset.org/abstracts/search?q=Mark%20Wilson"> Mark Wilson</a>, <a href="https://publications.waset.org/abstracts/search?q=Samuel%20Vine"> Samuel Vine</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Theory of Challenge and Threat States in Athletes (TCTSA) states that self-efficacy is an antecedent of challenge and threat. These states result from conscious and unconscious evaluations of situational demands and personal resources and are represented by both cognitive and physiological markers. Challenge is considered a more adaptive stress response as it is associated with a more efficient cardiovascular profile, as well as better performance and attention effects compared with threat. Self-efficacy is proposed to influence challenge/threat because an individual’s belief that they have the skills necessary to execute the courses of action required to succeed contributes to a perception that they can cope with the demands of the situation. This study experimentally examined the effects of self-efficacy on cardiovascular responses (challenge and threat), demand and resource evaluations, performance and attention under pressurised conditions. Forty-five university students were randomly assigned to either a control (n=15), low self-efficacy (n=15) or high self-efficacy (n=15) group and completed baseline and pressurised golf putting tasks. Self-efficacy was manipulated using false feedback adapted from previous studies. Measures of self-efficacy, cardiovascular reactivity, demand and resource evaluations, task performance and attention were recorded. The high self-efficacy group displayed more favourable cardiovascular reactivity, indicative of a challenge state, compared with the low self-efficacy group. The former group also reported high resource evaluations, but no task performance or attention effects were detected. These findings demonstrate that levels of self-efficacy influence cardiovascular reactivity and perceptions of resources under pressurised conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cardiovascular" title="cardiovascular">cardiovascular</a>, <a href="https://publications.waset.org/abstracts/search?q=challenge" title=" challenge"> challenge</a>, <a href="https://publications.waset.org/abstracts/search?q=performance" title=" performance"> performance</a>, <a href="https://publications.waset.org/abstracts/search?q=threat" title=" threat"> threat</a> </p> <a href="https://publications.waset.org/abstracts/75000/the-effects-of-self-efficacy-on-challenge-and-threat-states" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75000.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">232</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">135</span> The Application of Film-Induced Tourism in the Promotion of Nigeria: An Analysis of the Movie Up North</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samuel%20Onyije%20Igbedion">Samuel Onyije Igbedion</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Nigerian film industry, commonly known as Nollywood, has grown to become the second largest in the world in terms of the volumes of films produced. Many scholars have argued that the themes in most Nollywood films do not let themselves to the issue of film-induced tourism, which can be used to improve tourism in Nigeria and the economy at large. This study, therefore, seeks to examine the validity of this statement in the context of one film that attempts to address the issue. This paper examines the features of tourism-induced films to determine if tourism-inducing themes were used in the film and how they were used in order to confirm or refute the thesis statement. The agenda-setting theory of the media underpinned the study. A qualitative research approach was adopted and content analysis was used to review literature from relevant secondary sources that determined the content criteria, which was then used to analyze the film. The findings reveal that the filmmakers of Up North (2018) did feature themes and scenes that promoted tourism through the use and filming of exotic scenery. It also revealed that the film introduced these tourism-inducing features of the north through the setting, the storyline, the choice of locations and chosen shot types. The study concludes that the prominent and intentional featuring all of these beautiful scenery, history, culture, adventure activities and personalities point to a deliberate attempt at convincing the audiences of the tourist potential of Nigeria. Thus, the validity of the statement does not apply to the film Up North (2018). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=film-tourism" title="film-tourism">film-tourism</a>, <a href="https://publications.waset.org/abstracts/search?q=nollywood" title=" nollywood"> nollywood</a>, <a href="https://publications.waset.org/abstracts/search?q=agenda-setting%20theory" title=" agenda-setting theory"> agenda-setting theory</a>, <a href="https://publications.waset.org/abstracts/search?q=filmmaking" title=" filmmaking"> filmmaking</a>, <a href="https://publications.waset.org/abstracts/search?q=culture" title=" culture"> culture</a> </p> <a href="https://publications.waset.org/abstracts/164575/the-application-of-film-induced-tourism-in-the-promotion-of-nigeria-an-analysis-of-the-movie-up-north" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164575.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">77</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">134</span> An Assessment of Factors Affecting the Cost and Time Performance of Subcontractors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adedayo%20Jeremiah%20Adeyekun">Adedayo Jeremiah Adeyekun</a>, <a href="https://publications.waset.org/abstracts/search?q=Samuel%20Oluwagbemiga%20Ishola"> Samuel Oluwagbemiga Ishola</a>, <a href="https://publications.waset.org/abstracts/search?q="></a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper is an assessment of factors influencing the cost and time performance of subcontractors and the need for effective performance of subcontractors at the project sites. The factors influencing the performance of subcontractors are grouped, similar to those identified with the project or an organization and on another hand, there are significant factors influencing the performance of the subcontractors. These factors incorporate management level leadership, time required to complete the project, profit, staff capability/expertise, reputation, installment method, organization history, and project procurement method strategy, security, bidding technique, insurance, bond and relationship with the major contractors. The factors influencing the management of subcontractors in building development projects includes performance of significant past projects, standard of workmanship, consistence with guidelines, regular payment to labourers, adherence to program, regularity and viability of communication with main contractor, adherence to subcontract necessities. Other factors comprise adherence to statutory environmental regulations, number of experienced sites administrative staff, inspection and maintenance of good workplace, number of artisans and workers, quality of as-built and shop drawings and ability to carry out the quantity of work and so on. This study also aimed to suggest a way forward to improve the performance of subcontractors which is the reason for exceeding budget at the project sites. To carry out this study, a questionnaire was drafted to derive information on the causes of low performance of subcontractors and the implication to cost. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=performance" title="performance">performance</a>, <a href="https://publications.waset.org/abstracts/search?q=contractor" title=" contractor"> contractor</a>, <a href="https://publications.waset.org/abstracts/search?q=subcontractors" title=" subcontractors"> subcontractors</a>, <a href="https://publications.waset.org/abstracts/search?q=construction" title=" construction"> construction</a> </p> <a href="https://publications.waset.org/abstracts/163333/an-assessment-of-factors-affecting-the-cost-and-time-performance-of-subcontractors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163333.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">76</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">133</span> Quantifying and Prioritizing Agricultural Residue Biomass Energy Potential in Ethiopia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Angesom%20Gebrezgabiher%20Tesfay">Angesom Gebrezgabiher Tesfay</a>, <a href="https://publications.waset.org/abstracts/search?q=Afafaw%20Hailesilasie%20Tesfay"> Afafaw Hailesilasie Tesfay</a>, <a href="https://publications.waset.org/abstracts/search?q=Muyiwa%20Samuel%20Adaramola"> Muyiwa Samuel Adaramola</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The energy demand boost in Ethiopia urges sustainable fuel options while it is mainly supplemented by traditional biomass and imported conventional fuels. To satisfy the deficiency it has to be sourced from all renewables. Thus identifying resources and estimating potential is vital to the sector. This study aims at an in-depth assessment to quantify, prioritize, and analyze agricultural residue biomass energy and related characteristic forms. Biomass use management and modernization seeks successive information and a clue about the resource quantity and characteristic. Five years of crop yield data for thirteen crops were collected. Conversion factors for their 20 residues are surveyed from the literature. Then residues amount potentially available for energy and their energy is estimated regional, crop-wise, residue-wise, and shares compared. Their potential value for energy is analyzed from two perspectives and prioritized. The gross potential is estimated to be 495PJ, equivalent to 12/17 million tons of oil/coal. At 30% collection efficiency, it is the same as conventional fuel import in 2018. Maize and sorghum potential and spatial availability are preeminent. Cotton and maize presented the highest potential values for energy from application and resource perspectives. Oromia and Amhara regions' contributions are the highest. The resource collection and application trends are required for future management that implicates a prospective study. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=crop%20residue" title="crop residue">crop residue</a>, <a href="https://publications.waset.org/abstracts/search?q=biomass%20potential" title=" biomass potential"> biomass potential</a>, <a href="https://publications.waset.org/abstracts/search?q=biomass%20resource" title=" biomass resource"> biomass resource</a>, <a href="https://publications.waset.org/abstracts/search?q=Ethiopian%20energy" title=" Ethiopian energy"> Ethiopian energy</a> </p> <a href="https://publications.waset.org/abstracts/164687/quantifying-and-prioritizing-agricultural-residue-biomass-energy-potential-in-ethiopia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164687.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">124</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">132</span> An Academic Theory on a Sustainable Evaluation of Achatina Fulica Within Ethekwini, KwaZulu-Natal</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sibusiso%20Trevor%20Tshabalala">Sibusiso Trevor Tshabalala</a>, <a href="https://publications.waset.org/abstracts/search?q=Samuel%20Lubbe"> Samuel Lubbe</a>, <a href="https://publications.waset.org/abstracts/search?q=Vince%20Vuledzani%20Ndou"> Vince Vuledzani Ndou</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Dependency on chemicals has had many disadvantages in pest management control strategies. Such genetic rodenticide resistance and secondary exposure risk are what is currently being experienced. Emphasis on integrated pest management suggests that to control future pests, early intervention and economic threshold development are key starting points in crop production. The significance of this research project is to help establish a relationship between Giant African Land Snail (Achatina Fulica) solution extract, its shell chemical properties, and farmer’s perceptions of biological control in eThekwini Municipality Agri-hubs. A mixed design approach to collecting data will be explored using a trial layout in the field and through interviews. The experimental area will be explored using a split-plot design that will be replicated and arranged in a randomised complete block design. The split-plot will have 0, 10, 20 and 30 liters of water to one liter of snail solution extract. Plots were 50 m² each with a spacing of 12 m between each plot and a plant spacing of 0.5 m (inter-row) ‘and 0.5 m (intra-row). Trials will be irrigated using sprinkler irrigation, with objective two being added to the mix every 4-5 days. The expected outcome will be improved soil fertility and micro-organisms population proliferation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=giant%20african%20land%20snail" title="giant african land snail">giant african land snail</a>, <a href="https://publications.waset.org/abstracts/search?q=integrated%20pest%20management" title=" integrated pest management"> integrated pest management</a>, <a href="https://publications.waset.org/abstracts/search?q=photosynthesis" title=" photosynthesis"> photosynthesis</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20rodenticide%20resistance" title=" genetic rodenticide resistance"> genetic rodenticide resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=control%20future%20pests" title=" control future pests"> control future pests</a>, <a href="https://publications.waset.org/abstracts/search?q=shell%20chemical%20properties" title=" shell chemical properties"> shell chemical properties</a> </p> <a href="https://publications.waset.org/abstracts/155715/an-academic-theory-on-a-sustainable-evaluation-of-achatina-fulica-within-ethekwini-kwazulu-natal" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155715.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">104</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">131</span> The Effects of Varying Nutrient Conditions on Hydrogen Production in PGR5 Deficient C.

Reinahrdtii serves as one of the most promising organisms from which to obtain biological hydrogen. However, its production catalyst, [FeFe]-hydrogenase, is largely inhibited by the presence of oxygen. In recent years, researchers have identified a Proton Gradient Regulation 5 (PGR5) deficient mutant, which shows enhanced respiration and lower accumulations of oxygen within the system. In this research, we investigated the effects of varying nutrient conditions on PGR5 mutants' ability to produce hydrogen. After growing PGR5 mutants in varying nutrient conditions under 55W fluorescent lamps at 30℃ with constant stirring at 200 rpm, a common water displacement method was utilized to obtain a definitive volumetric reading of hydrogen produced by these mutants over a period of 12 days. After the trials, statistical t-tests and ANOVAs were performed to better determine the effect which nutrient conditions have on PGR5 mutants' ability to produce hydrogen. In this, we report that conditions of sulfur deprivation most optimally enhanced hydrogen production within these mutants, with groups grown under these conditions demonstrating the highest production capacity over the entire 12-day period. Similarly, it was found that when grown under conditions of nitrogen deprivation, a favorable shift towards carbon fixation and overall lipid/starch metabolism was observed. Overall, these results demonstrate that PGR5-deficient mutants stand as a promising source of biohydrogen when grown under conditions of sulfur deprivation. To date, photochemical characteristics of [FeFe]-hydrogenase in these mutants have yet to be investigated under conditions of sulfur deprivation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biofuel" title="biofuel">biofuel</a>, <a href="https://publications.waset.org/abstracts/search?q=biohydrogen" title=" biohydrogen"> biohydrogen</a>, <a href="https://publications.waset.org/abstracts/search?q=%5BFeFe%5D-hydrogenase" title=" [FeFe]-hydrogenase"> [FeFe]-hydrogenase</a>, <a href="https://publications.waset.org/abstracts/search?q=algal%20biofuel" title=" algal biofuel"> algal biofuel</a> </p> <a href="https://publications.waset.org/abstracts/160695/the-effects-of-varying-nutrient-conditions-on-hydrogen-production-in-pgr5-deficient-c-reinhardtii-mutants" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/160695.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">145</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">130</span> Integrated Microsystem for Multiplexed Genosensor Detection of Biowarfare Agents</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samuel%20B.%20Dulay">Samuel B.

In this work, an electrochemical genosensor array that allows simultaneous detection of different biowarfare agents within an integrated microsystem that provides an easy handling of the technology which combines a microfluidics setup with a multiplexing genosensor array has been developed and optimised for the following targets: Bacillus anthracis, Brucella abortis and melitensis, Bacteriophage lambda, Francisella tularensis, Burkholderia mallei and pseudomallei, Coxiella burnetii, Yersinia pestis, and Bacillus thuringiensis. The electrode array was modified via co-immobilisation of a 1:100 (mol/mol) mixture of a thiolated probe and an oligoethyleneglycol-terminated monopodal thiol. PCR products from these relevant biowarfare agents were detected reproducibly through a sandwich assay format with the target hybridised between a surface immobilised probe into the electrode and a horseradish peroxidase-labelled secondary reporter probe, which provided an enzyme based electrochemical signal. The potential of the designed microsystem for multiplexed genosensor detection and cross-reactivity studies over potential interfering DNA sequences has demonstrated high selectivity using the developed platform producing high-throughput. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biowarfare%20agents" title="biowarfare agents">biowarfare agents</a>, <a href="https://publications.waset.org/abstracts/search?q=genosensors" title=" genosensors"> genosensors</a>, <a href="https://publications.waset.org/abstracts/search?q=multipled%20detection" title=" multipled detection"> multipled detection</a>, <a href="https://publications.waset.org/abstracts/search?q=microsystem" title=" microsystem"> microsystem</a> </p> <a href="https://publications.waset.org/abstracts/42951/integrated-microsystem-for-multiplexed-genosensor-detection-of-biowarfare-agents" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42951.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">272</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">129</span> A Case Study on the Census of Technological Capacities in Health Care in Rural Sanitary Institutions in South Cameroon</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Doriane%20Micaela%20Andeme%20Bikoro">Doriane Micaela Andeme Bikoro</a>, <a href="https://publications.waset.org/abstracts/search?q=Samuel%20Fosso%20Wamba"> Samuel Fosso Wamba</a>, <a href="https://publications.waset.org/abstracts/search?q=Jean%20Robert%20Kala%20Kamdjoug"> Jean Robert Kala Kamdjoug</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Currently one of the leading fields in the market of technological innovation is digital health. In developed countries, this booming innovation is experiencing an exponential speed. We understand that in developed countries, e-health could also revolutionize the practice of medicine and therefore fill the many failures observed in medical care. Everything leads to believe that future technology is oriented towards the medical sector. The aim of this work is to explore at the same time the technological resources and the potential of health care based on new technologies; it is a case study in a rural area of Southern Cameroon. Among other things, we will make a census of the shortcomings and problems encountered, and we will propose various appropriate solutions. The work methodology used here is essentially qualitative. We used two qualitative data collection techniques, direct observation, and interviews. In fact, we spent two weeks in the field observing and conducting some semi-directive interviews with some of those responsible for these health structures. This study was conducted in three health facilities in the south of the country; including two health centers and a rural hospital. Many technological failures have been identified in the day-to-day management of these health facilities and especially in the administration of health care to patients. We note major problems such as the digital divide, the lack of qualified personnel, the state of isolation of this area. This is why various proposals are made to improve the health sector in Cameroon both technologically and medically. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cameroon" title="Cameroon">Cameroon</a>, <a href="https://publications.waset.org/abstracts/search?q=capacities" title=" capacities"> capacities</a>, <a href="https://publications.waset.org/abstracts/search?q=census" title=" census"> census</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20health" title=" digital health"> digital health</a>, <a href="https://publications.waset.org/abstracts/search?q=qualitative%20method" title=" qualitative method"> qualitative method</a>, <a href="https://publications.waset.org/abstracts/search?q=rural%20area" title=" rural area"> rural area</a> </p> <a href="https://publications.waset.org/abstracts/108904/a-case-study-on-the-census-of-technological-capacities-in-health-care-in-rural-sanitary-institutions-in-south-cameroon" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/108904.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">144</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">128</span> Effects of Plumage Colour on Measurable Attributes of Indigenous Chickens in North Central Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Joseph%20J.%20Okoh">Joseph J.

The overall average body weight of the chickens was 1.95 ± 0.03kg. The body weights of black, white, black/white, brown, black/brown, grey and mottled chicken however were 1.87 ± 0.04, 1.94 ± 0.04, 1.95 ± 0.03, 1.93 ± 0.03, 2.01 ± 0.04, 1.96 ± 0.04 and 1.94±0.14kg respectively. Only body length did not vary by plumage colour. The others; body weight and width, shank, comb and breast length, breast height (p < 0.001), beak and wing lengths (p < 0.001) varied significantly. Generally, no colour was outrightly superior to others in all body measurements. However, body weight and breast height were both highest in black/brown chickens which also had the second highest breast length. Body width, shank, beak, comb and wing lengths were highest in grey chickens but lowest in those with white colour and combinations. Egg quality was on the other hand mostly lowest in grey chickens. In selection for genetic improvement in body measurements, black/brown and grey chickens should be favoured. However, in view of the known negative relationship between body weight and egg attributes, selection in favour of grey plumage may result in chickens of poor egg attributes. Therefore, grey chickens should be selected against egg quality. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=body%20weight" title="body weight">body weight</a>, <a href="https://publications.waset.org/abstracts/search?q=indigenous%20chicken" title=" indigenous chicken"> indigenous chicken</a>, <a href="https://publications.waset.org/abstracts/search?q=measurements" title=" measurements"> measurements</a>, <a href="https://publications.waset.org/abstracts/search?q=plumage%20colour" title=" plumage colour"> plumage colour</a> </p> <a href="https://publications.waset.org/abstracts/101953/effects-of-plumage-colour-on-measurable-attributes-of-indigenous-chickens-in-north-central-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/101953.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">128</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">127</span> Solar Disinfection Potentials of Aqua Lens, Photovoltaic and Glass Bottle Subsequent to Plant‑Based Coagulant: For Low‑Cost Household Water Treatment Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yonas%20Lamore">Yonas Lamore</a>, <a href="https://publications.waset.org/abstracts/search?q=Abebe%20Beyene"> Abebe Beyene</a>, <a href="https://publications.waset.org/abstracts/search?q=Samuel%20Fekadu"> Samuel Fekadu</a>, <a href="https://publications.waset.org/abstracts/search?q=Moa%20Megersa"> Moa Megersa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Unaffordable construction cost of conventional water treatment plant and distribution system in most developing countries makes difficult to provide safe and adequate water for all households, especially for the rural setup. Water treatment at the source can be the best alternative. Solar disinfection is one alternative among point of use treatments. In this study, aqua lens, photovoltaic box and glass bottle were used subsequent to plant coagulants to evaluate microbial reduction potentials. Laboratory- and field-based experiments were conducted from May to August 2016. The Escherichia coli, total coliforms and heterotrophic plate counts were used as indicator organisms. The result indicated that aqua lens (AL), photovoltaic box (PV) and glass bottle (GB) have high inactivation rate subsequently almost for all indicator organisms in short solar exposure time. Total coliforms were inactivated in AL (SD = 15.8 °C, R2 = 0.92) followed by PV inactivation temperature associa- tion (SD = 11.6 C, R2 = 0.90), and the GB concentrator was inactivated (SD = 10.9 °C, R2 = 0.70) at turbidity level of 3.41 NTU. As the study indicated, aqua lens coupled with Moringa oleifera coagulant can be an effective with minimum cost for household water treatment system.

This study, therefore, assessed the feeding practices of children of 0-23 months of age among mothers in urban areas of Akure, Ondo State, Nigeria. Simple random sampling technique was used to select four hundred (400) mothers out of 710 mothers from 7 primary health care centres in Akure metropolis for the study. Data were collected using modified WHO 2003 Questionnaire on child feeding practices. Data were analyzed using descriptive statistics, while chi-square was used to determine the association between variables. Results showed that 52.0% of the children were males, with 47.5% in the 6-8 months age group. More than half (57.0%) of the mothers were between the ages of 20-29 years, and 45.0% had secondary education. Majority (94.3%) of the mothers breastfed their children in the last 24 hours preceding the survey. The feeding practices history of mothers showed that 28.0% and 53.7% of the mothers initiated breastfeeding less than 30 minutes and between 30 minutes to 1 hour after delivery, respectively. Also, 52.0% of mothers practiced exclusive breastfeeding for six months, while 26.2% breastfed from 6 months up to 2 years of age. Dietary diversity of the children age 6-23 months revealed that 68.7% of the children attained the minimum dietary diversity by consuming 4 or more food groups in the last 24 hours. There was a significant association (P < 0.05) between mothers’ education (n=180), occupation(n=41) and dietary diversity (n= 150) and meal frequency (n=209). Therefore, the study concluded that the duration of breastfeeding and time of introduction of complementary food did not meet WHO recommended guidelines.

On the one hand are adherents to the convergence thesis which is premised on the assumption that global social order is tending toward universalism which could translate into the possible end of the classical state system and the unification of world societies under a single and common ideological dispensation. The convergence thesis is hinged on the globalization process which is gradually reducing world societies into a 'global village'. On the other hand are intellectuals who hold the view that despite advances made in communication technology which appear to threaten the survival of the classical state system. Invariance, as expressed in the survival of the existing state system and the diverse social traditions in world societies, remain a realistic possibility contrary to the conclusions of the convergence thesis. The invariance thesis has been advanced by scholars like Samuel P. Huntington whose work on clash of civilizations suggests that world peace can only be sustained through the co-habitation of diverse civilizations across the world. The purpose of this paper is to examine both sides of the debate with the aim of making a realistic assessment on where world societies are headed, between convergence and invariance. Using the realist theory of international relations as our theoretical premise the paper argues that while there is sufficient ground to predict the future direction of world societies as headed towards some form of convergence, invariance as expressed in the co-existence of diverse civilizations will for a long time remain a major feature of the international system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=convergence" title="convergence">convergence</a>, <a href="https://publications.waset.org/abstracts/search?q=invariance" title=" invariance"> invariance</a>, <a href="https://publications.waset.org/abstracts/search?q=clash%20of%20civilization" title=" clash of civilization"> clash of civilization</a>, <a href="https://publications.waset.org/abstracts/search?q=classical%20state%20system" title=" classical state system"> classical state system</a>, <a href="https://publications.waset.org/abstracts/search?q=universalism" title=" universalism"> universalism</a> </p> <a href="https://publications.waset.org/abstracts/37539/the-world-in-the-21st-century-and-beyound-convergence-or-invariance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37539.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">307</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">124</span> Lime Based Products as a Maintainable Option for Repair And Restoration of Historic Buildings in India</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adedayo%20Jeremiah%20Adeyekun">Adedayo Jeremiah Adeyekun</a>, <a href="https://publications.waset.org/abstracts/search?q=Samuel%20Oluwagbemiga%20Ishola"> Samuel Oluwagbemiga Ishola</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research aims to study the use of traditional building materials for the repair and refurbishment of historic buildings in India and to provide an authentic treatment of historical buildings that will be highly considered by taking into consideration the new standards of rehabilitating process. This can be proven to be an effective solution over modern impervious material due to its compatibility with traditional building methods and materials. For example, their elastoplastic properties allow accommodating movement due to settlement or moisture/temperature changes without cracking. The use of lime also enhances workability, water retention and bond characteristics. Lime is considered to be a natural, traditional material, but it is also sustainable and energy-efficient, with production powered by biomass and emissions up to 25% less than cementitious materials. However, there is a lack of comprehensive data on the impact of lime‐based materials on the energy efficiency and thermal properties of traditional buildings and structures. Although lime mortars, renders and plasters were largely superseded by cement-based products in the first half of the 20th century, lime has a long and proven track record dating back to ancient times. This was used by the Egyptians in 4000BC to construct the pyramids. This doesn't mean that lime is an outdated technology, nor is it difficult to be used as a material. In fact, lime has a growing place in modern construction, with increasing numbers of designers choosing to use lime-based products because of their special properties. To carry out this research, some historic buildings will be surveyed and information will be derived from the textbooks and journals related to Architectural restoration. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lime" title="lime">lime</a>, <a href="https://publications.waset.org/abstracts/search?q=materials" title=" materials"> materials</a>, <a href="https://publications.waset.org/abstracts/search?q=historic" title=" historic"> historic</a>, <a href="https://publications.waset.org/abstracts/search?q=buildings" title=" buildings"> buildings</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a> </p> <a href="https://publications.waset.org/abstracts/143272/lime-based-products-as-a-maintainable-option-for-repair-and-restoration-of-historic-buildings-in-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143272.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">166</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">123</span> Development of an Integrated Route Information Management Software</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Oluibukun%20G.%20Ajayi">Oluibukun G.

This paper presents the summarized details of the development of a Route Information Management (RIM) software. The software, codenamed ‘AutoROUTE’, was encoded using Microsoft visual studio-visual basic package, and it offers complete automation of the computational procedures and plan production involved in route surveying. It was experimented using a route survey data (longitudinal profile and cross sections) of a 2.7 km road which stretches from Dama to Lunko village in Minna, Niger State, acquired with the aid of a Hi-Target DGPS receiver. The developed software (AutoROUTE) is capable of computing the various simple curve parameters, horizontal curve, and vertical curve, and it can also plot road alignment, longitudinal profile, and cross-section with a capability to store this on the SQL incorporated into the Microsoft visual basic software. The plotted plans with AutoROUTE were compared with the plans produced with the conventional AutoCAD Civil 3D software, and AutoROUTE proved to be more user-friendly and accurate because it plots in three decimal places whereas AutoCAD plots in two decimal places. Also, it was discovered that AutoROUTE software is faster in plotting and the stages involved is less cumbersome compared to AutoCAD Civil 3D software. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=automated%20systems" title="automated systems">automated systems</a>, <a href="https://publications.waset.org/abstracts/search?q=cross%20sections" title=" cross sections"> cross sections</a>, <a href="https://publications.waset.org/abstracts/search?q=curves" title=" curves"> curves</a>, <a href="https://publications.waset.org/abstracts/search?q=engineering%20construction" title=" engineering construction"> engineering construction</a>, <a href="https://publications.waset.org/abstracts/search?q=longitudinal%20profile" title=" longitudinal profile"> longitudinal profile</a>, <a href="https://publications.waset.org/abstracts/search?q=route%20surveying" title=" route surveying"> route surveying</a> </p> <a href="https://publications.waset.org/abstracts/107424/development-of-an-integrated-route-information-management-software" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/107424.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">148</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">122</span> Treatment of Healthcare Wastewater Using The Peroxi-Photoelectrocoagulation Process: Predictive Models for Chemical Oxygen Demand, Color Removal, and Electrical Energy Consumption</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samuel%20Fekadu%20A.">Samuel Fekadu A.</a>, <a href="https://publications.waset.org/abstracts/search?q=Esayas%20Alemayehu%20B."> Esayas Alemayehu B.</a>, <a href="https://publications.waset.org/abstracts/search?q=Bultum%20Oljira%20D."> Bultum Oljira D.</a>, <a href="https://publications.waset.org/abstracts/search?q=Seid%20Tiku%20D."> Seid Tiku D.</a>, <a href="https://publications.waset.org/abstracts/search?q=Dessalegn%20Dadi%20D."> Dessalegn Dadi D.</a>, <a href="https://publications.waset.org/abstracts/search?q=Bart%20Van%20Der%20Bruggen%20A."> Bart Van Der Bruggen A.</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The peroxi-photoelectrocoagulation process was evaluated for the removal of chemical oxygen demand (COD) and color from healthcare wastewater. A 2-level full factorial design with center points was created to investigate the effect of the process parameters, i.e., initial COD, H₂O₂, pH, reaction time and current density. Furthermore, the total energy consumption and average current efficiency in the system were evaluated. Predictive models for % COD, % color removal and energy consumption were obtained. The initial COD and pH were found to be the most significant variables in the reduction of COD and color in peroxi-photoelectrocoagulation process. Hydrogen peroxide only has a significant effect on the treated wastewater when combined with other input variables in the process like pH, reaction time and current density. In the peroxi-photoelectrocoagulation process, current density appears not as a single effect but rather as an interaction effect with H₂O₂ in reducing COD and color. Lower energy expenditure was observed at higher initial COD, shorter reaction time and lower current density. The average current efficiency was found as low as 13 % and as high as 777 %.

Studies on adolescent sexuality and pregnancy are very limited in our country. Therefore, this study aims at assessing the prevalence of teenage pregnancy and its determinants among school adolescents of Arba Minch town. Methods: Institution- based, cross-sectional study was conducted from 20-30 March 2014. Systematic sampling technique was used to select a total of 578 students from four schools of the town. Data were collected by trained data collectors using a pre-tested, self-administered structured questionnaire. The analysis was made using the software SPSS version 20.0 statistical packages. Multivariate logistic regression was used to identify the predictors of teenage pregnancy. Results: The prevalence of teenage pregnancy among school adolescents of Arba Minch town was 7.7%. Being grade11(AOR=4.6;95%CI:1.4,9.3) and grade12 student (AOR=5.8;95% CI:1.3,14.4), not knowing the correct time to take emergency contraceptives(AOR=3.3;95%CI:1.4,7.4), substance use(AOR=3.1;95%CI:1.1,8.8), living with either of biological parents (AOR=3.3;95%CI:1.1,8.7) and poor parent-daughter interaction (AOR=3.1;95%CI:1.1,8.7) were found to be significant predictors of teenage pregnancy. Conclusion: This study revealed a high level of teenage pregnancy among school adolescents of Arba Minch town. A significant number of adolescent female school students were at risk of facing the challenges of teenage pregnancy in the study area. School-based reproductive health education and strong parent-daughter relationships should be strengthened. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adolescent" title="adolescent">adolescent</a>, <a href="https://publications.waset.org/abstracts/search?q=Arba%20minch" title=" Arba minch"> Arba minch</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20factors" title=" risk factors"> risk factors</a>, <a href="https://publications.waset.org/abstracts/search?q=school" title=" school"> school</a>, <a href="https://publications.waset.org/abstracts/search?q=southern%20Ethiopia" title=" southern Ethiopia"> southern Ethiopia</a>, <a href="https://publications.waset.org/abstracts/search?q=teenage%20pregnancy" title=" teenage pregnancy"> teenage pregnancy</a> </p> <a href="https://publications.waset.org/abstracts/81154/determinants-of-teenage-pregnancy-the-case-of-school-adolescents-of-arba-minch-town-southern-ethiopia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81154.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">349</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">120</span> Strength Parameters and the Rate Process Theory Applied to Compacted Fadama Soils</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samuel%20Akinlabi%20Ola">Samuel Akinlabi Ola</a>, <a href="https://publications.waset.org/abstracts/search?q=Emeka%20Segun%20Nnochiri"> Emeka Segun Nnochiri</a>, <a href="https://publications.waset.org/abstracts/search?q=Stephen%20Kayode%20Aderomose"> Stephen Kayode Aderomose</a>, <a href="https://publications.waset.org/abstracts/search?q=Paul%20Ayesemhe%20Edoh"> Paul Ayesemhe Edoh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Fadama soils of Northern Nigeria are generally a problem soil for highway and geotechnical engineers. There has been no consistent conclusion on the effect of the strain rate on the shear strength of soils, thus necessitating the need to clarify this issue with various types of soil. Consolidated undrained tests with pore pressure measurements were conducted at optimum moisture content and maximum dry density using standard proctor compaction. Back pressures were applied to saturate the soil. The shear strength parameters were determined. Analyzing the results and model studies using the Rate Process Theory, functional relationships between the deviator stress and strain rate were determined and expressed mathematically as deviator stress = β0+ β1 log(strain rate) at each cell pressure where β0 and β1 are constants. Also, functional relationships between the pore pressure coefficient Āf and the time to failure were determined and expressed mathematically as pore pressure coefficient, Āf = ψ0+ѱ1log (time to failure) where ψ0 and ѱ1 are constants. For cell pressure between 69 – 310 kN/m2 (10 - 45psi) the constants found for Fadama soil in this study are ψ0=0.17 and ѱ1=0.18. The study also shows the dependence of the angle of friction (ø’) on the rate of strain as it increases from 22o to 25o for an increase in the rate of strain from 0.08%/min to 1.0%/min. Conclusively, the study also shows that within the strain rate utilized in the research, the deviator strength increased with the strain rate while the excess pore water pressure decreased with an increase in the rate of strain. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=deviator%20stress" title="deviator stress">deviator stress</a>, <a href="https://publications.waset.org/abstracts/search?q=Fadama%20soils" title=" Fadama soils"> Fadama soils</a>, <a href="https://publications.waset.org/abstracts/search?q=pore%20pressure%20coefficient" title=" pore pressure coefficient"> pore pressure coefficient</a>, <a href="https://publications.waset.org/abstracts/search?q=rate%20process" title=" rate process"> rate process</a> </p> <a href="https://publications.waset.org/abstracts/171947/strength-parameters-and-the-rate-process-theory-applied-to-compacted-fadama-soils" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171947.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">76</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">119</span> Relational Effect of Parent Interest, Basic School Attended, Gender, and Scare of Basic School Mathematics Teacher on Student Interest in Mathematics </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yarhands%20Dissou%20Arthur">Yarhands Dissou Arthur</a>, <a href="https://publications.waset.org/abstracts/search?q=Samuel%20Asiedu%20Addo"> Samuel Asiedu Addo</a>, <a href="https://publications.waset.org/abstracts/search?q=Jonathan%20Annan"> Jonathan Annan </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Interest in subject specific is very essential in the quest to ensure effective teaching and learning. In building interest in subject specific areas requires certain factors and strategies well-spelled out.The factors such as the gender of the student, the type of basic school attended, the parent interest as well as the scare of the basic school mathematics teacher is very important to consider. The relational effect and the contribution these above mentioned variables on student have not been fully investigated and this paper address the effect of these factors on the student interest. In the attainment of this goal, the current paper addresses the effect of parent interest, the type of basic school attended, the scare by basic school mathematics teacher and its effect on student’s interest in mathematics. A cross sectional data collected from two hundred and sixty post-secondary school student were analyzed using descriptive and inferential statistical methods by aid of SPSS version 16. The study found that parent interest and value for mathematics significantly influenced students interest and joy in solving mathematical problems. Moreover, we also observed that the fear imposed by basic school mathematics teachers was found to significantly influence students’ interest. The study further found that the type of basic school attended and gender are factors that do not influence students’ interest in mathematics. In addition to concluding that a student’s interest is influenced by both parent interest and the fear of basic school mathematics teacher, the study also showed that the type of basic school attended and gender does not affect the students’ interest in mathematics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gender" title="gender">gender</a>, <a href="https://publications.waset.org/abstracts/search?q=mathematics%20interest" title=" mathematics interest"> mathematics interest</a>, <a href="https://publications.waset.org/abstracts/search?q=teacher%20interest" title=" teacher interest"> teacher interest</a>, <a href="https://publications.waset.org/abstracts/search?q=teacher%20interest" title=" teacher interest"> teacher interest</a>, <a href="https://publications.waset.org/abstracts/search?q=student%20interest" title=" student interest"> student interest</a> </p> <a href="https://publications.waset.org/abstracts/41372/relational-effect-of-parent-interest-basic-school-attended-gender-and-scare-of-basic-school-mathematics-teacher-on-student-interest-in-mathematics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41372.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">367</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">118</span> Preparation of Carbon Nanofiber Reinforced HDPE Using Dialkylimidazolium as a Dispersing Agent: Effect on Thermal and Rheological Properties</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=J.%20Samuel">J.

The prepared samples were characterized by thermogravimetric (TGA) and differential scanning calorimetric (DSC) analyses. The samples blended with imidazolium ionic liquid exhibit higher thermal stability. DSC analysis showed clear miscibility of ionic liquid in the HDPE matrix and showed single endothermic peak. The melt rheological analysis of HDPE/CNF composites was performed using an oscillatory rheometer. The influence of CNF and ionic liquid concentration (ranging from 0, 0.5, and 1 wt%) on the viscoelastic parameters was investigated at 200 °C with an angular frequency range of 0.1 to 100 rad/s. The rheological analysis shows the shear-thinning behavior for the composites. An improvement in the viscoelastic properties was observed as the nanofiber concentration increases. The progress in the modulus values was attributed to the structural rigidity imparted by the high aspect ratio CNF. The modulus values and complex viscosity of the composites increased significantly at low frequencies. Composites blended with ionic liquid exhibit slightly lower values of complex viscosity and modulus over the corresponding HDPE/CNF compositions. Therefore, reduction in melt viscosity is an additional benefit for polymer composite processing as a result of wetting effect by polymer-ionic liquid combinations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=high-density%20polyethylene" title="high-density polyethylene">high-density polyethylene</a>, <a href="https://publications.waset.org/abstracts/search?q=carbon%20nanofibers" title=" carbon nanofibers"> carbon nanofibers</a>, <a href="https://publications.waset.org/abstracts/search?q=ionic%20liquid" title=" ionic liquid"> ionic liquid</a>, <a href="https://publications.waset.org/abstracts/search?q=complex%20viscosity" title=" complex viscosity"> complex viscosity</a> </p> <a href="https://publications.waset.org/abstracts/97964/preparation-of-carbon-nanofiber-reinforced-hdpe-using-dialkylimidazolium-as-a-dispersing-agent-effect-on-thermal-and-rheological-properties" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/97964.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">127</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">117</span> Central Finite Volume Methods Applied in Relativistic Magnetohydrodynamics: Applications in Disks and Jets</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Raphael%20de%20Oliveira%20Garcia">Raphael de Oliveira Garcia</a>, <a href="https://publications.waset.org/abstracts/search?q=Samuel%20Rocha%20de%20Oliveira"> Samuel Rocha de Oliveira</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We have developed a new computer program in Fortran 90, in order to obtain numerical solutions of a system of Relativistic Magnetohydrodynamics partial differential equations with predetermined gravitation (GRMHD), capable of simulating the formation of relativistic jets from the accretion disk of matter up to his ejection. Initially we carried out a study on numerical methods of unidimensional Finite Volume, namely Lax-Friedrichs, Lax-Wendroff, Nessyahu-Tadmor method and Godunov methods dependent on Riemann problems, applied to equations Euler in order to verify their main features and make comparisons among those methods. It was then implemented the method of Finite Volume Centered of Nessyahu-Tadmor, a numerical schemes that has a formulation free and without dimensional separation of Riemann problem solvers, even in two or more spatial dimensions, at this point, already applied in equations GRMHD. Finally, the Nessyahu-Tadmor method was possible to obtain stable numerical solutions - without spurious oscillations or excessive dissipation - from the magnetized accretion disk process in rotation with respect to a central black hole (BH) Schwarzschild and immersed in a magnetosphere, for the ejection of matter in the form of jet over a distance of fourteen times the radius of the BH, a record in terms of astrophysical simulation of this kind. Also in our simulations, we managed to get substructures jets.

Administered questionnaires were used to collect data from household members and a key informant interview held with health and veterinary workers. Multi stage sampling was used to obtain participants’ knowledge, attitudes and practices. Questions were scored and descriptively analyzed using Excel spreadsheet then exported to GenStat Discovery Edition 4. Results: A total of 293 community members were recruited in this study. The overall level of knowledge was 77.9% of all community members regarding cause, transmission, symptoms and prevention of the disease in both humans and animals. Majority of the participants (96.3%) had heard about anthrax. A total of 99 (33.8%) correspondents had seen a person with anthrax and 75.1% think that anthrax is a very serious disease in the area. Of the interviewed correspondents, 14.3% of them have had their animals (mostly cattle) suffer from anthrax while 15.7% had either suffered from anthrax or have had their family member who suffered from anthrax. Conclusion: The study findings indicate above average knowledge on cause, symptoms, transmission and prevention of anthrax among community members in humans and animals. Practices in this study were still risk among community members. Veterinary and Medical health planners should design anthrax awareness interventions as a team targeting to reach these communities and the public through barazas, radio, CHW and other communication channel on a regular basis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anthrax" title="anthrax">anthrax</a>, <a href="https://publications.waset.org/abstracts/search?q=attitudes" title=" attitudes"> attitudes</a>, <a href="https://publications.waset.org/abstracts/search?q=Kenya" title=" Kenya"> Kenya</a>, <a href="https://publications.waset.org/abstracts/search?q=knowledge" title=" knowledge"> knowledge</a>, <a href="https://publications.waset.org/abstracts/search?q=Maragua" title=" Maragua"> Maragua</a>, <a href="https://publications.waset.org/abstracts/search?q=practices" title=" practices"> practices</a> </p> <a href="https://publications.waset.org/abstracts/51734/knowledge-attitudes-and-practices-regarding-anthrax-among-community-members-health-and-veterinary-workers-in-maragua-kenya" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/51734.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">317</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">115</span> Towards a Sustainable Energy Future: Method Used in Existing Buildings to Implement Sustainable Energy Technologies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Georgi%20Vendramin">Georgi Vendramin</a>, <a href="https://publications.waset.org/abstracts/search?q=Aurea%20L%C3%BAcia"> Aurea Lúcia</a>, <a href="https://publications.waset.org/abstracts/search?q=Yamamoto"> Yamamoto</a>, <a href="https://publications.waset.org/abstracts/search?q=Carlos%20Itsuo"> Carlos Itsuo</a>, <a href="https://publications.waset.org/abstracts/search?q=Souza%20Melegari"> Souza Melegari</a>, <a href="https://publications.waset.org/abstracts/search?q=N.%20Samuel"> N.

The model is based on a healthy balance equations purely theoretical and empirical data. Simplified equations are derived through a synthesis of the measured data obtained from meteorological stations. The implementation of the model in a design tool integrated buildings is discussed in this article, to better punctuate the requirements of comfort and energy efficiency in architecture and engineering. Sustainability, energy efficiency, and the integration of alternative energy systems and concepts are beginning to be incorporated into designs for new buildings and renovations to existing buildings. Few means have existed to effectively validate the potential performance benefits of the design concepts. It was used a method of degree-days for an assessment of the energy performance of a building showed that the design of the architectural design should always be considered the materials used and the size of the openings. The energy performance was obtained through the model, considering the location of the building Central Park Shopping Mall, in the city of Cascavel - PR. Obtained climatic data of these locations and in a second step, it was obtained the coefficient of total heat loss in the building pre-established so evaluating the thermal comfort and energy performance. This means that the more openings in buildings in Cascavel – PR, installed to the east side, they may be higher because the glass added to the geometry of architectural spaces will cause the environment conserve energy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sustainable%20design" title="sustainable design">sustainable design</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20modeling" title=" energy modeling"> energy modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=design%20validation" title=" design validation"> design validation</a>, <a href="https://publications.waset.org/abstracts/search?q=degree-days%20methods" title=" degree-days methods"> degree-days methods</a> </p> <a href="https://publications.waset.org/abstracts/11925/towards-a-sustainable-energy-future-method-used-in-existing-buildings-to-implement-sustainable-energy-technologies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11925.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">420</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">114</span> Factors Associated with Rural-Urban Migration and Its Associated Health Hazards on the Female Adolescents in Kumasi Metropolis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Freda%20Adomaa">Freda Adomaa</a>, <a href="https://publications.waset.org/abstracts/search?q=Samuel%20Oppong%20Boampong"> Samuel Oppong Boampong</a>, <a href="https://publications.waset.org/abstracts/search?q=Charles%20Gyamfi%20Rahman"> Charles Gyamfi Rahman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The living and working environment of migrants and their access to healthcare services induce good or poor health. This study was conducted to assess the factors associated with rural-urban migration and its associated health hazards among female adolescents. A sample size of two hundred (200) was chosen in which all responded to questionnaires comprising closed-ended questions, which were distributed to gather data from the respondents, after which it was analyzed using the Statistical Package for Social Sciences (SPSS) version 20. The utilized three causes of rural-urban migration thus political, economic and socio-cultural. The study revealed that political situations such as regional inequality (65.4%) and ethnic conflicts (78.2%) whereas economic factors such as lack of amenities (82.3%), lack of employment in rural communities (77.4%), lack of education (74%), and poverty (85.3%) as well as socio-cultural factors such as divorced parents (65.6%), media influence (79.1%), family conflicts (59.4%) and appealing urban informal sector (65.2%) are major causes of migration. Respondents’ encountered challenges such as poor remuneration for services (87.2%), being maltreated by a colleague or worker (69%), sleeping in open space (73.3%), and harassment by the task force (71.4%) and teenage pregnancies (58.5%). The study concluded that the three variables play a key role in adolescent migration and when they travel they end up getting involved in serious health hazardous behaviors such as rapes as well as physical and psychological harassments’. The study, therefore, recommends that vocational training of the rural people on small scale industries (non-farm) activities that could generate an income for the rural household should be introduced. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rural" title="rural">rural</a>, <a href="https://publications.waset.org/abstracts/search?q=urban" title=" urban"> urban</a>, <a href="https://publications.waset.org/abstracts/search?q=migration" title=" migration"> migration</a>, <a href="https://publications.waset.org/abstracts/search?q=female%20health%20hazards" title=" female health hazards"> female health hazards</a> </p> <a href="https://publications.waset.org/abstracts/134074/factors-associated-with-rural-urban-migration-and-its-associated-health-hazards-on-the-female-adolescents-in-kumasi-metropolis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/134074.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">133</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">113</span> Battery Energy Storage System Economic Benefits Assessment on a Network Frequency Control</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kr%C3%A9hi%20Serge%20Agbli">Kréhi Serge Agbli</a>, <a href="https://publications.waset.org/abstracts/search?q=Samuel%20Portebos"> Samuel Portebos</a>, <a href="https://publications.waset.org/abstracts/search?q=Micha%C3%ABl%20Salomon"> Michaël Salomon</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Here a methodology is considered aiming at evaluating the economic benefit of the provision of a primary frequency control unit using a Battery Energy Storage System (BESS). In this methodology, two control types (basic and hysteresis) are implemented and the corresponding minimum energy storage system power allowing to maintain the frequency drop inside a given threshold under a given contingency is identified and compared using DigSilent’s PowerFactory software. Following this step, the corresponding energy storage capacity (in MWh) is calculated. As PowerFactory is dedicated to dynamic simulation for transient analysis, a first order model related to the IEEE 9 bus grid used for the analysis under PowerFactory is characterized and implemented on MATLAB-Simulink. Primary frequency control is simulated using the two control types over one-month grid's frequency deviation data on this Simulink model. This simulation results in the energy throughput both basic and hysteresis BESSs. It emerges that the 15 minutes operation band of the battery capacity allocated to frequency control is sufficient under the considered disturbances. A sensitivity analysis on the width of the control deadband is then performed for the two control types. The deadband width variation leads to an identical sizing with the hysteresis control showing a better frequency control at the cost of a higher delivered throughput compared to the basic control. An economic analysis comparing the cost of the sized BESS to the potential revenues is then performed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=battery%20energy%20storage%20system" title="battery energy storage system">battery energy storage system</a>, <a href="https://publications.waset.org/abstracts/search?q=electrical%20network%20frequency%20stability" title=" electrical network frequency stability"> electrical network frequency stability</a>, <a href="https://publications.waset.org/abstracts/search?q=frequency%20control%20unit" title=" frequency control unit"> frequency control unit</a>, <a href="https://publications.waset.org/abstracts/search?q=PowerFactor" title=" PowerFactor"> PowerFactor</a> </p> <a href="https://publications.waset.org/abstracts/127919/battery-energy-storage-system-economic-benefits-assessment-on-a-network-frequency-control" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/127919.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">129</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">112</span> Cannabidiol (CBD) Resistant Salmonella Strains Are Susceptible to Epsilon 34 Phage Tailspike Protein</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ibrahim%20Iddrisu">Ibrahim Iddrisu</a>, <a href="https://publications.waset.org/abstracts/search?q=Joseph%20Ayariga"> Joseph Ayariga</a>, <a href="https://publications.waset.org/abstracts/search?q=Junhuan%20Xu"> Junhuan Xu</a>, <a href="https://publications.waset.org/abstracts/search?q=Ayomide%20Adebanjo"> Ayomide Adebanjo</a>, <a href="https://publications.waset.org/abstracts/search?q=Boakai%20K.%20Robertson"> Boakai K.

Due to the emergence of pan drug-resistant bacteria, most antibiotics have lost their efficacy. Bacteriophages or their components are known to target bacterial cell walls, cell membranes, and lipopolysaccharides (LPS) and hydrolyze them. Bacteriophages, being the natural predators of pathogenic bacteria, are inevitably categorized as ‘human friends’, thus fulfilling the adage that ‘the enemy of my enemy is my friend’. Leveraging on their lethal capabilities against pathogenic bacteria, researchers are searching for more ways to overcome the current antibiotic resistance challenge. In this study, we expressed and purified epsilon 34 phage tail spike protein (E34 TSP) from the E34 TSP gene, then assessed the ability of this bacteriophage protein in the killing of two CBD-resistant strains of Salmonella spp. We also assessed the ability of the tail spike protein to cause bacteria membrane disruption and dehydrogenase depletion. We observed that the combined treatment of CBD-resistant strains of Salmonella with CBD and E34 TSP showed poor killing ability, whereas the mono treatment with E34 TSP showed considerably higher killing efficiency. This study demonstrates that the inhibition of the bacteria by E34 TSP was due in part to membrane disruption and dehydrogenase inactivation by the protein. The results of this work provide an interesting background to highlight the crucial role phage proteins such as E34 TSP could play in pathogenic bacterial control. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cannabidiol" title="cannabidiol">cannabidiol</a>, <a href="https://publications.waset.org/abstracts/search?q=resistance" title=" resistance"> resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=Salmonella" title=" Salmonella"> Salmonella</a>, <a href="https://publications.waset.org/abstracts/search?q=antimicrobials" title=" antimicrobials"> antimicrobials</a>, <a href="https://publications.waset.org/abstracts/search?q=phages" title=" phages"> phages</a> </p> <a href="https://publications.waset.org/abstracts/182735/cannabidiol-cbd-resistant-salmonella-strains-are-susceptible-to-epsilon-34-phage-tailspike-protein" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/182735.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">70</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">111</span> Implications of Dehusking and Aqueous Soaking on Anti-nutrients, Phytochemical Screening and Antioxidants Properties of Jack Beans (Canavalia Ensiformis L.

One of these food sources has been identified as Canavalia enisiformis, or jack beans. The only issue with using jack beans is that they contain anti-nutrient chemicals, which must be removed or diminished in order for them to be fit for human consumption. The objective of this study is to determine the nutritional and industrial utility of Canavalia enisiformis by analysing the anti-nutrient, phytochemical, and antioxidant composition of raw whole seed and soaking dehusked seeds using established procedures. Phytate (23.48±0.24, 15.24±0.41 and 14.83±0.00), oxalate (4.32±0.09, 3.96±0.09 and 2.88±0.09), tannins (22.77±0.73, 18.68±0.03 and 17.50±0.46), and lectins (6.67±0.04, 6.20±0.01 and 6.42±0.07) exhibited the highest anti-nutrient values in raw whole seed and, at the very least, in dehusked, soaked seeds. The samples were subjected to phytochemical screening, which detected the presence of cardiac glycosides as well as anthraquinones, alkaloids, tannins, saponins, steroids, flavonoids, terpenoids, phlobatannins, and flavonoids. Due to the reduction in phytochemical contents quantified as a result of dehusking and soaking, phenolbatannins and anthraquinones were not found in the samples. The research findings also demonstrated elevated concentrations of several plausible phytochemical components with potential medical value, with the raw whole seed exhibiting the greatest capacity to scavenge free radicals. Accordingly, the study's findings validate the seed's therapeutic applications and imply that it might be an inexpensive source of antioxidants for humans and animals alike. <p
