sphincter muscle strength of voluntary contraction is essential in initial assessment and assessment of efficacy of rehabilitation of patients with faecal incontinence (FI) and obstructed defecation (OD). The present study was conducted to evaluate the digital assessment of the external anal sphincter muscle strength of voluntary contraction by using Modified Oxford Scale (MOS) in comparison to anal manometry squeeze pressure. The present cross-sectional study included 65 patients. There were 40 patients (61.5 %) with FI and 25 patients (38.5 %) with OD. All patients were subjected to history taking, clinical examination including assessment of the external anal sphincter muscle strength of voluntary contraction by using MOS and anal manometry (mean squeeze pressure and maximal squeeze pressure). There was a statistically significant positive correlation between MOS and anal manometry squeeze pressures including mean squeeze pressure and maximal squeeze pressure among FI group and OD group. In conclusion, assessment of the external anal sphincter muscle strength of voluntary contraction by using MOS is a valid method and can substitute anal manometry assessment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anal%20manometry" title="anal manometry">anal manometry</a>, <a href="https://publications.waset.org/abstracts/search?q=external%20anal%20sphincter%20muscle" title=" external anal sphincter muscle"> external anal sphincter muscle</a>, <a href="https://publications.waset.org/abstracts/search?q=Modified%20Oxford%20Scale" title=" Modified Oxford Scale"> Modified Oxford Scale</a>, <a href="https://publications.waset.org/abstracts/search?q=muscle%20strength" title=" muscle strength"> muscle strength</a> </p> <a href="https://publications.waset.org/abstracts/32483/evaluation-of-digital-assessment-of-anal-sphincter-muscle-strength" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32483.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">416</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">1021</span> Pelvic Floor Electrophysiology Patterns Associated with Obstructed Defecation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emmanuel%20Kamal%20Aziz%20Saba">Emmanuel Kamal Aziz Saba</a>, <a href="https://publications.waset.org/abstracts/search?q=Gihan%20Abd%20El-Lateif%20Younis%20El-Tantawi"> Gihan Abd El-Lateif Younis El-Tantawi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Hamdy%20Zahran"> Mohammed Hamdy Zahran</a>, <a href="https://publications.waset.org/abstracts/search?q=Ibrahim%20Khalil%20Ibrahim"> Ibrahim Khalil Ibrahim</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Abd%20El-Salam%20Shehata"> Mohammed Abd El-Salam Shehata</a>, <a href="https://publications.waset.org/abstracts/search?q=Hussein%20Al-Moghazy%20Sultan"> Hussein Al-Moghazy Sultan</a>, <a href="https://publications.waset.org/abstracts/search?q=Medhat"> Medhat </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Pelvic floor electrophysiological tests are essential for assessment of patients with obstructed defecation. The present study was conducted to determine the different patterns of pelvic floor electrophysiology that are associated with obstructed defecation. The present cross sectional study included 25 patients with obstructed defecation. A control group of 20 apparently healthy subjects were included. All patients were subjected to history taking, clinical examination, proctosigmoidoscopy, lateral proctography (evacuation proctography), dynamic pelvic magnetic resonance imaging, anal manometry and electrophysiological studies. Electrophysiological studies were including pudendal nerve motor conduction study, pudendo-anal reflex, needle electromyography of external anal sphincter and puborectalis muscles, pudendal somatosensory evoked potential and tibial somatosensory evoked potential. The control group was subjected to electrophysiological studies which included pudendal nerve motor conduction study, pudendo-anal reflex, pudendal somatosensory evoked potential and tibial somatosensory evoked potential. The most common pelvic floor electrodiagnostic pattern characteristics of obstructed defecation was pudendal neuropathy, denervation and anismus of external anal sphincter and puborectalis with complete interference pattern of external anal sphincter and puborectalis at squeezing and cough and no localized defect in external anal sphincter. In conclusion, there were characteristic pelvic floor electrodiagnostic patterns associated with obstructed defecation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=obstructed%20defecation" title="obstructed defecation">obstructed defecation</a>, <a href="https://publications.waset.org/abstracts/search?q=pudendal%20nerve%20terminal%20motor%20latency" title=" pudendal nerve terminal motor latency"> pudendal nerve terminal motor latency</a>, <a href="https://publications.waset.org/abstracts/search?q=pudendoanal%20reflex" title=" pudendoanal reflex"> pudendoanal reflex</a>, <a href="https://publications.waset.org/abstracts/search?q=sphincter%20electromyography" title=" sphincter electromyography"> sphincter electromyography</a> </p> <a href="https://publications.waset.org/abstracts/30915/pelvic-floor-electrophysiology-patterns-associated-with-obstructed-defecation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30915.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">439</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">1020</span> Powers of Class p-w A (s, t) Operators Associated with Generalized Aluthge Transformations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Husein%20Mohammed%20Rashid">Mohammed Husein Mohammed Rashid</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Let Τ = U |Τ| be a polar decomposition of a bounded linear operator T on a complex Hilbert space with ker U = ker |T|.

Data were collected from a sample of 160 fatteners between June 2010 and June 2011 using the multistage random sampling technique. Translog stochastic frontier production function was employed for the analysis. Results of the analysis show that technical efficiency indices varied from 0.74 to 0.98%, with a mean of 0.90%, indicating that there was no wide gap between the efficiency of best technical efficient fatteners and that of the average fattener. The result also showed that fattening experience and herd size influenced the level of technical efficiency at 1% levels. It is recommended that credit agencies should ensure that credit made available to the fatteners is monitored to ensure appropriate utilization. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=technical%20efficiency" title="technical efficiency">technical efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=determinants" title=" determinants"> determinants</a>, <a href="https://publications.waset.org/abstracts/search?q=cattle" title=" cattle"> cattle</a>, <a href="https://publications.waset.org/abstracts/search?q=fattening%20enterprises" title=" fattening enterprises"> fattening enterprises</a> </p> <a href="https://publications.waset.org/abstracts/48489/analysis-of-technical-efficiency-and-its-determinants-among-cattle-fattening-enterprises-in-kebbi-state-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48489.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">451</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">1018</span> Assessment of Solid Waste Management in General Mohammed Inuwa Wushishi Housing Estate, Minna, Niger State, Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Garba%20Inuwa%20Kuta">Garba Inuwa Kuta</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed"> Mohammed</a>, <a href="https://publications.waset.org/abstracts/search?q=Adamu"> Adamu</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Ahmed%20Emigilati"> Mohammed Ahmed Emigilati</a>, <a href="https://publications.waset.org/abstracts/search?q=Ibrahim%20Ishiaku"> Ibrahim Ishiaku</a>, <a href="https://publications.waset.org/abstracts/search?q=Kudu%20Dangana"> Kudu Dangana</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study sought to identify the problems of solid waste management in General Mohammed InuwaWushishi Housing Estate. The two broad types of data, the secondary and primary data were used in the study. Questionnaires and personal observations were also used to collect some of the data. Factors impeding the effective and efficient solid waste management were identified. The study revealed that sacks disposal method and open dumping are the most commonly used method of disposal, about 30.0% of the respondent use sacks disposal method in the estate while 24.9% dump their refuse on the floor. Wrong attitudes and perceptions of the people about sanitation issues contributed to solid waste management problems of General Mohammed InuwaWushishi Housing Estate. Majority of the households did not educate their members on the need to clean their surroundings and refuse to buy drum for waste disposal from Niger State Environmental Protection Agency (NISEPA) on the basis that the drums are expensive. Virtually, all the people depended on Niger State Environmental Protection Agency (NISEPA) facilities for the disposal of their household refuse. Solid waste management problems were partly the results of NISEPA’s inability to cope with the situation because of lack of equipment. It was recommended that there should be an increase in enlightenment to the people on domestic waste disposal to keep the surroundings clean. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=housing%20estate" title="housing estate">housing estate</a>, <a href="https://publications.waset.org/abstracts/search?q=assessment" title=" assessment"> assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=solid%20waste" title=" solid waste"> solid waste</a>, <a href="https://publications.waset.org/abstracts/search?q=disposal" title=" disposal"> disposal</a>, <a href="https://publications.waset.org/abstracts/search?q=management" title=" management"> management</a> </p> <a href="https://publications.waset.org/abstracts/29043/assessment-of-solid-waste-management-in-general-mohammed-inuwa-wushishi-housing-estate-minna-niger-state-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29043.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">650</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">1017</span> Women Entrepreneurs’ in Nigeria: Issues and Challenges</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Mainoma">Mohammed Mainoma</a>, <a href="https://publications.waset.org/abstracts/search?q=Abubakar%20Tijanni"> Abubakar Tijanni</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Aliyu"> Mohammed Aliyu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Globalization has brought a structural change in industry. It is the breaking of artificial boundaries and given way to new product, new service, new market, and new technology among others. It leads to the realization that men entrepreneurs’ alone cannot meet the demand of the teeming population. Therefore there is a need for the participation, involvement, and engagement of females in the production and distribution of goods and services. This will enhance growth and development of a nation. It is in line with the above that this paper attempt to discuss meaning of women entrepreneurs, roles, types, problems, and prospects.

The paper analyses a television interview with the Crown Prince Mohammed Bin Salman who talks about the progress of the Saudi vision of 2030, and how the government had acted as response to the COVID-19 pandemic. The interview was on 28/4/2021. The paper analyses the tweets on Twitter that cover the interview for the purpose of investigating the development of concepts and meanings regarding the Saudi peoples’ orientations towards the Saudi projects. The data include all related tweets from the day of the interview and the following seven days after the interview. The finding of the collocation analysis suggests that nationalism notion is explicitly expressed by users in Twitter. The main finding of this paper suggests the importance of further analyses for the concordance lines. However, the collocation network suggests that there is a clear highlight for nationalism. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=social%20media" title="social media">social media</a>, <a href="https://publications.waset.org/abstracts/search?q=twitter" title=" twitter"> twitter</a>, <a href="https://publications.waset.org/abstracts/search?q=political%20interview" title=" political interview"> political interview</a>, <a href="https://publications.waset.org/abstracts/search?q=prince%20Mohammed%20Bin%20Salman" title=" prince Mohammed Bin Salman"> prince Mohammed Bin Salman</a>, <a href="https://publications.waset.org/abstracts/search?q=Saudi%20vision%202030" title=" Saudi vision 2030"> Saudi vision 2030</a> </p> <a href="https://publications.waset.org/abstracts/146201/analysing-social-media-coverage-of-political-speeches-in-relation-to-discourse-and-context" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146201.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">191</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">1015</span> FPGA Implementation of RSA Encryption Algorithm for E-Passport Application</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khaled%20Shehata">Khaled Shehata</a>, <a href="https://publications.waset.org/abstracts/search?q=Hanady%20Hussien"> Hanady Hussien</a>, <a href="https://publications.waset.org/abstracts/search?q=Sara%20Yehia"> Sara Yehia</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Securing the data stored on E-passport is a very important issue. RSA encryption algorithm is suitable for such application with low data size. In this paper the design and implementation of 1024 bit-key RSA encryption and decryption module on an FPGA is presented.

To our knowledge, few researchers have evaluated the combined antimicrobial effect of inorganic nanoparticles (NPs) with bioorganic pesticides for controlling plant pathogens in the greenhouse and open field, decontrol investigated synergistic effect. In the current project, we will develop eco-friendly alternative management strategies including the use of heavy nanometal-tolerant Trichoderma strains and the main effective material in conventional fungicides (curpic, sulfur, phosphorus and zinc) for controlling plant diseases. Studies on bioefficacy and the mechanism of the nanocides against the most important plant diseases in Egypt were evaluated. There is a growing need to establish mechanisms of action for nano bio and/or fungicides to assist the design of new compounds or combinations of compounds, in order to understand resistance mechanisms and to provide a focus for toxicological attention.

In this study, the effect of process temperature and biomass-to-water ratio (B/W) on the fuel properties of hydrochar produced from wood shavings was investigated. HTC was conducted in an autoclave using reaction temperature of 230 °C and 260 °C for 20 minutes with B/W ratio of 0.11 to 0.43. The produced hydrochars were characterised by the mass yield (MY), higher heating value (HHV), proximate and ultimate properties. The results showed that the properties of the hydrochars improved with increasing process temperature and B/W ratio. The higher heating value (HHV) increased to 26.74 MJ/kg as the severity of the reaction was increased to the process temperature of 260 °C. Also, the atomic H/C and O/C ratios of hydrochars produced at 230 °C and 260 °C were closed to the regions of a peat and lignite on the plotted van Krevelen diagram. Hence, the produced hydrochar has a promising potential as a sustainable solid biofuel for energy application. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wood%20shavings" title="wood shavings">wood shavings</a>, <a href="https://publications.waset.org/abstracts/search?q=biomass%2Fwater%20ratio" title=" biomass/water ratio"> biomass/water ratio</a>, <a href="https://publications.waset.org/abstracts/search?q=thermochemical%20conversion" title=" thermochemical conversion"> thermochemical conversion</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrothermal%20carbonization" title=" hydrothermal carbonization"> hydrothermal carbonization</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrochar" title=" hydrochar"> hydrochar</a> </p> <a href="https://publications.waset.org/abstracts/172680/solid-biofuel-production-by-hydrothermal-carbonization-of-wood-shavings-effect-of-carbonization-temperature-and-biomass-to-water-ratio-on-hydrochars-properties" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/172680.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">116</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">1009</span> Orientational Pair Correlation Functions Modelling of the LiCl6H2O by the Hybrid Reverse Monte Carlo: Using an Environment Dependence Interaction Potential</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Habchi">Mohammed Habchi</a>, <a href="https://publications.waset.org/abstracts/search?q=Sidi%20Mohammed%20Mesli"> Sidi Mohammed Mesli</a>, <a href="https://publications.waset.org/abstracts/search?q=Rafik%20Benallal"> Rafik Benallal</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Kotbi"> Mohammed Kotbi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> On the basis of four partial correlation functions and some geometric constraints obtained from neutron scattering experiments, a Reverse Monte Carlo (RMC) simulation has been performed in the study of the aqueous electrolyte LiCl6H2O at the glassy state. The obtained 3-dimensional model allows computing pair radial and orientational distribution functions in order to explore the structural features of the system. Unrealistic features appeared in some coordination peaks. To remedy to this, we use the Hybrid Reverse Monte Carlo (HRMC), incorporating an additional energy constraint in addition to the usual constraints derived from experiments. The energy of the system is calculated using an Environment Dependence Interaction Potential (EDIP).

Some studies reported their advantageous effect in decreasing inflammation, and other studies reported that their use is associated with colitis aggravation. This study aimed to use specifically formulated trehalose-based nano-carriers that targets the colon in an attempt to alleviate inflammation caused by NSAIDs. L-α-phosphatidylcholine (PL), trehalose, and transcutol were used to prepare the trehalosomes (THs), which were also loaded with Tenoxicam(TXM) as a model NSAID. To optimize the formulation variables, a full 23 factorial design, using Design-Expert® software, was performed. The optimized formulation composed of trehalose: PL at a weight ratio of 1:1, 377.72 mg transcutol, and sonicated for 4 min, possessed a spherical shape with a size of 268.61 nm and EE% of 97.83% and released 70.22% of its drug content over 24 h. The superior protective action of TXM loaded THs compared to TXM suspension and drug-free THs was shown by the inhibition of the inflammatory biomarkers, namely; IL-1ß, IL-6, and TNF-alpha levels, as well as oxidative stress markers, measured as GSH and MDA. Improved histopathology of the colonic tissue in male New Zealand rabbits also confirmed the superiority of the TXM loaded THs compared to the unformulated drug or the drug free nano-carriers. Our findings highlight the prosperous role of THs in colon targeting and its anti-inflammatory characteristics in guarding against possible NSAIDs-driven exacerbation of colitis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=inflammatory%20bowel%20disease" title="inflammatory bowel disease">inflammatory bowel disease</a>, <a href="https://publications.waset.org/abstracts/search?q=trehalose" title=" trehalose"> trehalose</a>, <a href="https://publications.waset.org/abstracts/search?q=trehalosomes" title=" trehalosomes"> trehalosomes</a>, <a href="https://publications.waset.org/abstracts/search?q=colon%20targeting" title=" colon targeting"> colon targeting</a> </p> <a href="https://publications.waset.org/abstracts/149309/trehalose-based-nanocarriers-for-alleviation-of-inflammation-in-colitis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149309.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">138</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">1007</span> Experimental and Numerical Investigation of Fluid Flow inside Concentric Heat Exchanger Using Different Inlet Geometry Configurations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20M.%20Abo%20Elazm">Mohamed M.

Methane has the potential of causing global warming 25 times more than CO₂, and can potentially affect human life and environment. Thus, this research aims to determine MSW generation and the annual CH₄ emissions from the generated waste in Oman over the years 1971-2030. The estimation of total waste generation was performed using existing models, while the CH₄ emissions estimation was performed using the intergovernmental panel on climate change (IPCC) default method. It is found that total MSW generation in Oman might be reached 3,089 Gg in the year 2030, which approximately produced 85 Gg of CH₄ emissions in the year 2030. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=methane" title="methane">methane</a>, <a href="https://publications.waset.org/abstracts/search?q=emissions" title=" emissions"> emissions</a>, <a href="https://publications.waset.org/abstracts/search?q=landfills" title=" landfills"> landfills</a>, <a href="https://publications.waset.org/abstracts/search?q=solid%20waste" title=" solid waste"> solid waste</a> </p> <a href="https://publications.waset.org/abstracts/36440/quantification-of-methane-emissions-from-solid-waste-in-oman-using-ipcc-default-methodology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36440.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">510</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">1005</span> The Effect of Artificial Intelligence on Construction Development</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shady%20Gamal%20Aziz%20Shehata">Shady Gamal Aziz Shehata</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Difficulty in defining construction quality arises due to perception based on the nature and requirements of the market, the different partners themselves and the results they want. Quantitative research was used in this constructivist research. A case-based study was conducted to assess the structures of positive attitudes and expectations in the context of quality improvement. A survey based on expert opinions was analyzed among construction organizations/companies operating in the construction industry in Pakistan. The financial strength, management structure and construction experience of the construction companies formed the basis of their selection. A good concept is visible at the project level and is seen as the most valuable part of the construction project. Each quality improvement technique was expected to increase the user's profits by improving the efficiency of the construction project. The Survey is useful for construction professionals to evaluate current construction concepts and expectations for the application of quality improvement techniques in construction projects. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=correlation%20analysis" title="correlation analysis">correlation analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=lean%20construction%20tools" title=" lean construction tools"> lean construction tools</a>, <a href="https://publications.waset.org/abstracts/search?q=lean%20construction" title=" lean construction"> lean construction</a>, <a href="https://publications.waset.org/abstracts/search?q=logistic%20regression%20analysis" title=" logistic regression analysis"> logistic regression analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20management" title=" risk management"> risk management</a>, <a href="https://publications.waset.org/abstracts/search?q=safety%20construction%20quality" title=" safety construction quality"> safety construction quality</a>, <a href="https://publications.waset.org/abstracts/search?q=expectation" title=" expectation"> expectation</a>, <a href="https://publications.waset.org/abstracts/search?q=improvement" title=" improvement"> improvement</a>, <a href="https://publications.waset.org/abstracts/search?q=perception" title=" perception"> perception</a> </p> <a href="https://publications.waset.org/abstracts/185149/the-effect-of-artificial-intelligence-on-construction-development" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185149.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">59</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">1004</span> Effects of Unfamiliar Orthography on the Lexical Encoding of Novel Phonological Features</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Asmaa%20Shehata">Asmaa Shehata</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Prior research indicates that second language (L2) learners encounter difficulty in the distinguishing novel L2 contrasting sounds that are not contrastive in their native languages. L2 orthographic information, however, is found to play a positive role in the acquisition of non-native phoneme contrasts. While most studies have mainly involved a familiar written script (i.e., the Roman script), the influence of a foreign, unfamiliar script is still unknown. Therefore, the present study asks: Does unfamiliar L2 script play a role in creating distinct phonological representations of novel contrasting phonemes? It is predicted that subjects’ performance in the unfamiliar orthography group will outperform their counterparts’ performance in the control group. Thus, training that entails orthographic inputs can yield a significant improvement in L2 adult learners’ identification and lexical encoding of novel L2 consonant contrasts. Results are discussed in terms of their implications for the type of input introduced to L2 learners to improve their language learning. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arabic" title="Arabic">Arabic</a>, <a href="https://publications.waset.org/abstracts/search?q=consonant%20contrasts" title=" consonant contrasts"> consonant contrasts</a>, <a href="https://publications.waset.org/abstracts/search?q=foreign%20script" title=" foreign script"> foreign script</a>, <a href="https://publications.waset.org/abstracts/search?q=lexical%20encoding" title=" lexical encoding"> lexical encoding</a>, <a href="https://publications.waset.org/abstracts/search?q=orthography" title=" orthography"> orthography</a>, <a href="https://publications.waset.org/abstracts/search?q=word%20learning" title=" word learning"> word learning</a> </p> <a href="https://publications.waset.org/abstracts/55226/effects-of-unfamiliar-orthography-on-the-lexical-encoding-of-novel-phonological-features" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55226.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">256</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">1003</span> Morphological Features Fusion for Identifying INBREAST-Database Masses Using Neural Networks and Support Vector Machines </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nadia%20el%20Atlas">Nadia el Atlas</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20el%20Aroussi"> Mohammed el Aroussi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Wahbi"> Mohammed Wahbi </a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper a novel technique of mass characterization based on robust features-fusion is presented. The proposed method consists of mainly four stages: (a) the first phase involves segmenting the masses using edge information’s. (b) The second phase is to calculate and fuse the most relevant morphological features. (c) The last phase is the classification step which allows us to classify the images into benign and malignant masses. In this step we have implemented Support Vectors Machines (SVM) and Artificial Neural Networks (ANN), which were evaluated with the following performance criteria: confusion matrix, accuracy, sensitivity, specificity, receiver operating characteristic ROC, and error histogram. The effectiveness of this new approach was evaluated by a recently developed database: INBREAST database. The fusion of the most appropriate morphological features provided very good results. The SVM gives accuracy to within 64.3%. Whereas the ANN classifier gives better results with an accuracy of 97.5%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=breast%20cancer" title="breast cancer">breast cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=mammography" title=" mammography"> mammography</a>, <a href="https://publications.waset.org/abstracts/search?q=CAD%20system" title=" CAD system"> CAD system</a>, <a href="https://publications.waset.org/abstracts/search?q=features" title=" features"> features</a>, <a href="https://publications.waset.org/abstracts/search?q=fusion" title=" fusion"> fusion</a> </p> <a href="https://publications.waset.org/abstracts/22407/morphological-features-fusion-for-identifying-inbreast-database-masses-using-neural-networks-and-support-vector-machines" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22407.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">599</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">1002</span> An Analysis of the Influence of Employee Readiness for Change on TQM Implementation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20%20Haffar">Mohamed Haffar</a>, <a href="https://publications.waset.org/abstracts/search?q=Khalil%20Al-Hyari"> Khalil Al-Hyari</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Khair%20Abu%20Zaid"> Mohammed Khair Abu Zaid</a>, <a href="https://publications.waset.org/abstracts/search?q=Ramadane%20Djbarni"> Ramadane Djbarni</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Hamdan"> Mohammed Hamdan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> While employee readiness for change (ERFC) is recognised as critical for total quality management (TQM) implementation, there is a lack of systematic and empirical studies regarding the relationship between ERFC dimensions and TQM. Therefore, this study proposes to fill this gap by providing empirical evidence leading to advancement in the understanding of the influences of ERFC components on TQM implementation. The empirical data for this study was drawn from a survey of 400 middle and senior managers of Jordanian firms. The analysis of the collected data, which was conducted using Structural Equation Modeling technique, revealed that three of the ERFC components, namely personally beneficial, change self-efficacy and management support are the most supportive ERFC dimensions for TQM implementation. Therefore, this paper makes a novel contribution by providing a refined and deeper comprehension of the relationships between ERFCs and TQM implementation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=total%20quality%20management" title="total quality management">total quality management</a>, <a href="https://publications.waset.org/abstracts/search?q=employee%20readiness%20for%20change" title=" employee readiness for change"> employee readiness for change</a>, <a href="https://publications.waset.org/abstracts/search?q=manufacturing%20organisations" title=" manufacturing organisations"> manufacturing organisations</a>, <a href="https://publications.waset.org/abstracts/search?q=Jordan" title=" Jordan"> Jordan</a> </p> <a href="https://publications.waset.org/abstracts/51327/an-analysis-of-the-influence-of-employee-readiness-for-change-on-tqm-implementation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/51327.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">559</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">1001</span> Cadmium Removal from Aqueous Solution Using Chitosan Beads Prepared from Shrimp Shell Extracted Chitosan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bendjaballah%20Malek%3B%20Makhlouf%20Mohammed%20Rabeh%3B%20Boukerche%20Imane%3B%20Benhamza%20Mohammed%20El%20Hocine">Bendjaballah Malek; Makhlouf Mohammed Rabeh; Boukerche Imane; Benhamza Mohammed El Hocine</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, chitosan was derived from Parapenaeus longirostris shrimp shells sourced from a local market in Annaba, eastern Algeria. The extraction process entailed four chemical stages: demineralization, deproteinization, decolorization, and deacetylation. The degree of deacetylation was calculated to be 80.86 %. The extracted chitosan was physically altered to synthesize chitosan beads and characterized via FTIR and XRD analysis. These beads were employed to eliminate cadmium ions from synthetic water. The batch adsorption process was optimized by analyzing the impact of contact time, pH, adsorbent dose, and temperature. The adsorption capacity of and Cd+2 on chitosan beads was found to be 6.83 mg/g and 7.94 mg/g, respectively. The kinetic adsorption of Cd+2 conformed to the pseudo-first-order model, while the isotherm study indicated that the Langmuir Isotherm model well described the adsorption of cadmium . A thermodynamic analysis demonstrated that the adsorption of Cd+2 on chitosan beads is spontaneous and exothermic. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cd" title="Cd">Cd</a>, <a href="https://publications.waset.org/abstracts/search?q=chitosan" title=" chitosan"> chitosan</a>, <a href="https://publications.waset.org/abstracts/search?q=chitosanbeds" title=" chitosanbeds"> chitosanbeds</a>, <a href="https://publications.waset.org/abstracts/search?q=bioadsorbent" title=" bioadsorbent"> bioadsorbent</a> </p> <a href="https://publications.waset.org/abstracts/167473/cadmium-removal-from-aqueous-solution-using-chitosan-beads-prepared-from-shrimp-shell-extracted-chitosan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167473.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">101</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">1000</span> On the Performance of Improvised Generalized M-Estimator in the Presence of High Leverage Collinearity Enhancing Observations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Habshah%20Midi">Habshah Midi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20A.%20Mohammed"> Mohammed A.

The ridge regression is the commonly used method to rectify this problem. However, the ridge regression cannot handle the problem of multicollinearity which is caused by high leverage collinearity enhancing observation (HLCEO). Since high leverage points (HLPs) are responsible for inducing multicollinearity, the effect of HLPs needs to be reduced by using Generalized M estimator. The existing GM6 estimator is based on the Minimum Volume Ellipsoid (MVE) which tends to swamp some low leverage points. Hence an improvised GM (MGM) estimator is presented to improve the precision of the GM6 estimator. Numerical example and simulation study are presented to show how HLPs can cause multicollinearity. The numerical results show that our MGM estimator is the most efficient method compared to some existing methods. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=identification" title="identification">identification</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20leverage%20points" title=" high leverage points"> high leverage points</a>, <a href="https://publications.waset.org/abstracts/search?q=multicollinearity" title=" multicollinearity"> multicollinearity</a>, <a href="https://publications.waset.org/abstracts/search?q=GM-estimator" title=" GM-estimator"> GM-estimator</a>, <a href="https://publications.waset.org/abstracts/search?q=DRGP" title=" DRGP"> DRGP</a>, <a href="https://publications.waset.org/abstracts/search?q=DFFITS" title=" DFFITS"> DFFITS</a> </p> <a href="https://publications.waset.org/abstracts/55345/on-the-performance-of-improvised-generalized-m-estimator-in-the-presence-of-high-leverage-collinearity-enhancing-observations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55345.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">262</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">999</span> Improvement of Antibacterial Activity for Ceftazidime by Partially Purified Tannase from Penicillium expansum</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sahira%20N.%20Muslim">Sahira N.

Gallic acid is used for manufacturing of trimethoprim. In the present study, a local fungal strain of <em>Penicillium expansum</em> A<sub>4</sub> isolated from spoilt apple samples gave the highest production level of tannase. Tannase was partially purified with a recovery yield of 92.52% and 6.32 fold of purification by precipitation using ammonium sulfate at 50% saturation. Tannase led to increased antimicrobial activity of ceftazidime against<em> Pseudomonas aeruginosa</em> and<em> S. aureus</em> and had a synergism effect at low concentrations of ceftazidime, and thus, tannase may be a useful adjuvant agent for the treatment of many bacterial infections in combination with ceftazidime. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ceftazidime" title="ceftazidime">ceftazidime</a>, <a href="https://publications.waset.org/abstracts/search?q=Penicillium%20expansum" title=" Penicillium expansum"> Penicillium expansum</a>, <a href="https://publications.waset.org/abstracts/search?q=tannase" title=" tannase"> tannase</a>, <a href="https://publications.waset.org/abstracts/search?q=antimicrobial%20activity" title=" antimicrobial activity"> antimicrobial activity</a> </p> <a href="https://publications.waset.org/abstracts/65967/improvement-of-antibacterial-activity-for-ceftazidime-by-partially-purified-tannase-from-penicillium-expansum" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65967.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">741</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">998</span> Design and Study of a Parabolic Trough Solar Collector for Generating Electricity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20A.%20A.%20Aboalnour">A.

However, the mechanism of antitrypanosomal activity is yet to be elucidated. In the present study, molecular docking was used to decipher the mode of interaction and binding affinity of stigmasterol to three known antitrypanosomal drug targets viz; adenosine kinase, ornithine decarboxylase and triose phosphate isomerase. Stigmasterol was found to bind to the selected trypanosomal enzymes with minimum binding energy of -4.2, -6.5 and -6.6 kcal/mol for adenosine kinase, ornithine decarboxylase, and triose phosphate isomerase respectively. However, hydrogen bond was not involved in the interaction of stigmasterol with all the three enzymes, but hydrophobic interaction seemed to play a vital role in the binding phenomenon which was predicted to be non-competitive like type of inhibition. It was concluded that binding to the three selected enzymes, especially triose phosphate isomerase, might be involved in the antitrypanosomal activity of stigmasterol but not mediated via a hydrogen bond interaction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antitrypanosomal" title="antitrypanosomal">antitrypanosomal</a>, <a href="https://publications.waset.org/abstracts/search?q=in%20silico" title=" in silico"> in silico</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20docking" title=" molecular docking"> molecular docking</a>, <a href="https://publications.waset.org/abstracts/search?q=stigmasterol" title=" stigmasterol"> stigmasterol</a> </p> <a href="https://publications.waset.org/abstracts/76195/antitrypanosomal-activity-of-stigmasterol-an-in-silico-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76195.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">278</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">996</span> Beta-Carotene Attenuates Cognitive and Hepatic Impairment in Thioacetamide-Induced Rat Model of Hepatic Encephalopathy via Mitigation of MAPK/NF-κB Signaling Pathway</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marawan%20Abd%20Elbaset%20Mohamed">Marawan Abd Elbaset Mohamed</a>, <a href="https://publications.waset.org/abstracts/search?q=Hanan%20A.%20Ogaly"> Hanan A.

Hepatic encephalopathy (HE) is one of its most common complications affecting liver and brain cognitive function. Beta-Carotene (B-Car) is an organic, strongly colored red-orange pigment abundant in fungi, plants, and fruits. The study attempted to know B-Car neuroprotective potential against thioacetamide (TAA)-induced neurotoxicity and cognitive decline in HE in rats. Hepatic encephalopathy was induced by TAA (100 mg/kg, i.p.) three times per week for two weeks. B-Car was given orally (10 or 20 mg/kg) daily for two weeks after TAA injections. Organ body weight ratio, Serum transaminase activities, liver’s antioxidant parameters, ammonia, and liver histopathology were assessed. Also, the brain’s mitogen-activated protein kinase (MAPK), nuclear factor kappa B (NF-κB), antioxidant parameters, adenosine triphosphate (ATP), adenosine monophosphate (AMP), norepinephrine (NE), dopamine (DA), serotonin (5-HT), 5-hydroxyindoleacetic acid (5-HIAA) cAMP response element-binding protein (CREB) expression and B-cell lymphoma 2 (Bcl-2) expression were measured. The brain’s cognitive functions (Spontaneous locomotor activity, Rotarod performance test, Object recognition test) were assessed. B-Car prevented alteration of the brain’s cognitive function in a dose-dependent manner. The histopathological outcomes supported these biochemical evidences. Based on these results, it could be established that B-Car could be assigned to treat the brain’s neurotoxicity consequences of HE via downregualtion of MAPK/NF-κB signaling pathways. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=beta-carotene" title="beta-carotene">beta-carotene</a>, <a href="https://publications.waset.org/abstracts/search?q=liver%20injury" title=" liver injury"> liver injury</a>, <a href="https://publications.waset.org/abstracts/search?q=MAPK" title=" MAPK"> MAPK</a>, <a href="https://publications.waset.org/abstracts/search?q=NF-%CE%BAB" title="NF-κB">NF-κB</a>, <a href="https://publications.waset.org/abstracts/search?q=rat" title=" rat"> rat</a>, <a href="https://publications.waset.org/abstracts/search?q=thioacetamide" title=" thioacetamide"> thioacetamide</a> </p> <a href="https://publications.waset.org/abstracts/148316/beta-carotene-attenuates-cognitive-and-hepatic-impairment-in-thioacetamide-induced-rat-model-of-hepatic-encephalopathy-via-mitigation-of-mapknf-kb-signaling-pathway" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148316.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">154</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">995</span> Silymarin Reverses Scopolamine-Induced Memory Deficit in Object Recognition Test in Rats: A Behavioral, Biochemical, Histopathological and Immunohistochemical Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Salma%20A.%20El-Marasy">Salma A.

This study aims to elucidate the possible ameliorative effect of silymarin on scopolamine-induced dementia using the object recognition test (ORT). The study was extended to demonstrate the role of cholinergic activity, oxidative stress, neuroinflammation, brain neurotransmitters and histopathological changes in the anti-amnestic effect of silymarin in demented rats. Wistar rats were pretreated with silymarin (200, 400, 800 mg/kg) or donepezil (10 mg/kg) orally for 14 consecutive days. Dementia was induced after the last drug administration by a single intraperitoneal dose of scopolamine (16 mg/kg). Then behavioral, biochemical, histopathological, and immunohistochemical analyses were then performed. Rats pretreated with silymarin counteracted scopolamine-induced non-spatial working memory impairment in the ORT and decreased acetylcholinesterase (AChE) activity, reduced malondialdehyde (MDA), elevated reduced glutathione (GSH), restored gamma-aminobutyric acid (GABA) and dopamine (DA) contents in the cortical and hippocampal brain homogenates. Silymarin dose-dependently reversed scopolamine-induced histopathological changes. Immunohistochemical analysis showed that silymarin dose-dependently mitigated protein expression of a glial fibrillary acidic protein (GFAP) and nuclear factor kappa-B (NF-κB) in the brain cortex and hippocampus. All these effects of silymarin were similar to that of the standard anti-amnestic drug, donepezil. This study reveals that the ameliorative effect of silymarin on scopolamine-induced dementia in rats using the ORT maybe in part mediated by, enhancement of cholinergic activity, anti-oxidant and anti-inflammatory activities as well as mitigation in brain neurotransmitters and histopathological changes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dementia" title="dementia">dementia</a>, <a href="https://publications.waset.org/abstracts/search?q=donepezil" title=" donepezil"> donepezil</a>, <a href="https://publications.waset.org/abstracts/search?q=object%20recognition%20test" title=" object recognition test"> object recognition test</a>, <a href="https://publications.waset.org/abstracts/search?q=rats" title=" rats"> rats</a>, <a href="https://publications.waset.org/abstracts/search?q=silymarin" title=" silymarin"> silymarin</a>, <a href="https://publications.waset.org/abstracts/search?q=scopolamine" title=" scopolamine"> scopolamine</a> </p> <a href="https://publications.waset.org/abstracts/90170/silymarin-reverses-scopolamine-induced-memory-deficit-in-object-recognition-test-in-rats-a-behavioral-biochemical-histopathological-and-immunohistochemical-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/90170.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">138</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">994</span> Genetics of Birth and Weaning Weight of Holstein, Friesians in Sudan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Safa%20A.%20Mohammed%20Ali">Safa A.

The traits studied were:*Weight at birth *Weight at weaning. The study also included some of the important factors that affected these traits. The data were analyzed using Harvey’s Least Squares and Maximum Likelihood programme. The results obtained showed that the overall mean weight at birth of the calves under study was 34.36±0.94kg. Male calves were found to be heavier than females; the difference between the sexes was highly significant (P<0.001). The mean weight at birth of male calves was 34.27±1.17 kg while that of females was 32.51±1.14kg. The effect of sex of calves, sire and parity of dam were highly significant (P<0.001). The overall mean of weight at weaning was 67.10 ± 5.05 kg, weight at weaning was significantly (p<0.001) effected by sex of calves, sire, year and season of birth have highly significant (P<0.001) effect on either trait. Also estimates heritabilities of birth weight was (0.033±0.015) lower than heritabilities of weaning weight (0.224±0.039), and genetic correlation was 0.563, the phenotypic correlation 0.281, and the environmental correlation 0.268. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=birth" title="birth">birth</a>, <a href="https://publications.waset.org/abstracts/search?q=weaning" title=" weaning"> weaning</a>, <a href="https://publications.waset.org/abstracts/search?q=weight" title=" weight"> weight</a>, <a href="https://publications.waset.org/abstracts/search?q=friesian" title=" friesian"> friesian</a> </p> <a href="https://publications.waset.org/abstracts/28077/genetics-of-birth-and-weaning-weight-of-holstein-friesians-in-sudan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28077.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">665</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">993</span> Quick Sequential Search Algorithm Used to Decode High-Frequency Matrices</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20M.%20Siddeq">Mohammed M.

This algorithm is applied to high-frequency coefficients for compression/encoding. The algorithm starts by converting every three coefficients to a single value; this is accomplished based on three different keys. The decoding/decompression uses a search method called QSS (Quick Sequential Search) Decoding Algorithm presented in this research based on the sequential search to recover the exact coefficients. In the next step, the decoded data are saved in an auxiliary array. The basic idea behind the auxiliary array is to save all possible decoded coefficients; this is because another algorithm, such as conventional sequential search, could retrieve encoded/compressed data independently from the proposed algorithm. The experimental results showed that our proposed decoding algorithm retrieves original data faster than conventional sequential search algorithms. <p class="card-text"><strong>Keywords:</strong> <a
