Today, the principles of sustainable development lead us to think over longer time frames, to take into account new issues and the operating costs of green energy. DR Congo (sub-Saharan Africa) still suffers from the unusability of certain bio-sourced materials (such as bamboo, branches, etc.) and the lack of energy, i.e. 9% of the population has access to electricity and 21% of access to water. Ecoconstruction involves the energy performance of buildings which carry out a dynamic thermal simulation, which targets the different assumptions and conventional parameters (weather, occupancy, materials, thermal comfort, green energies, etc.). The objective of this article is to remedy the thermal, economic and technical artisanal problems in an aqueous environment in the city of Kinshasa. In order to establish a behavioral model to mitigate environmental impacts on architectural modifications and low-cost eco-construction through the approach of innovation and design thinking. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=thermal%20comfort" title="thermal comfort">thermal comfort</a>, <a href="https://publications.waset.org/abstracts/search?q=bio-sourced%20material" title=" bio-sourced material"> bio-sourced material</a>, <a href="https://publications.waset.org/abstracts/search?q=eco-architecture" title=" eco-architecture"> eco-architecture</a>, <a href="https://publications.waset.org/abstracts/search?q=eco-construction" title=" eco-construction"> eco-construction</a>, <a href="https://publications.waset.org/abstracts/search?q=squatting" title=" squatting"> squatting</a>, <a href="https://publications.waset.org/abstracts/search?q=design%20thinking" title=" design thinking"> design thinking</a> </p> <a href="https://publications.waset.org/abstracts/176499/modeling-comfort-by-thermal-inertia-in-eco-construction-for-low-income-people-in-an-aqueous-environment-in-the-face-of-sustainable-development-in-sub-saharan-africa-case-of-the-city-of-kinshasa-dr-congo" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/176499.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">87</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">45</span> Challenges of Technical and Engineering Students in the Application of Scientific Cancer Knowledge to Preserve the Future Generation in Sub-Saharan Africa</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20Shaloom%20Mbambu">K.

Two-girls on five are private of Global Education, which represents a real loss to the development of communities and countries. Cultural traditions, poverty, violence, early and forced marriages, early pregnancies, and many other gender inequalities were the causes of this cancer development. Namely, "it is no more efficient development tool that is educating girls." The non-schooling of girls and their lack of supervision by liberal professions have serious consequences for the life of each of them. To improve the conditions of their inferior status, girls to men introduce poverty and health risks. Raising awareness among parents and communities on the importance of girls' education, improving children's access to school, girl-boy equality with their rights, creating income, and generating activities for girls, girls, and girls learning of liberal trades to make them self-sufficient.

The model is based on nonlinear partial differential equations, using the Yakam Matrix to account for the interaction between solid, liquid, and solid phases. This framework incorporates the influence of environmental factors, particularly water or rain on the runway, on braking performance and aircraft stability. Given the absence of exact analytical solutions, our approach enhances the understanding of key physical phenomena, including Coulomb friction forces, hydrodynamic effects, and the deformation of the pavement under the aircraft's load. Additionally, the dynamics of aquaplaning are simulated numerically to estimate the braking performance limits on wet surfaces, thereby contributing to strategies aimed at minimizing risk during landing on wet runways. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aircraft" title="aircraft">aircraft</a>, <a href="https://publications.waset.org/abstracts/search?q=modeling" title=" modeling"> modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=yakam%20matrix" title=" yakam matrix"> yakam matrix</a>, <a href="https://publications.waset.org/abstracts/search?q=contact" title=" contact"> contact</a>, <a href="https://publications.waset.org/abstracts/search?q=wet%20runway" title=" wet runway"> wet runway</a> </p> <a href="https://publications.waset.org/abstracts/194905/solid-liquid-solid-interface-of-yakam-matrix-mathematical-modeling-of-the-contact-between-an-aircraft-landing-gear-and-a-wet-pavement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/194905.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">7</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">42</span> Oil Reservoirs Bifurcation Analysis in the Democratic Republic of Congo: Fractal Characterization Approach of Makelekese MS-25 Field</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Leonard%20Mike%20McNelly%20Longwa">Leonard Mike McNelly Longwa</a>, <a href="https://publications.waset.org/abstracts/search?q=Divine%20Kusosa%20Musiku"> Divine Kusosa Musiku</a>, <a href="https://publications.waset.org/abstracts/search?q=D.%20Nahum%20Kabeya"> D.

Recommender systems are starting to incorporate reinforcement learning since it easily satisfies this goal of increasing a user’s reward every session. In this paper, we examine the most effective Reinforcement Learning agent tactics on the Movielens (1M) dataset, balancing precision and a variety of recommendations. The absence of variability in final predictions makes simplistic techniques, although able to optimize ranking quality criteria, worthless for consumers of the recommendation system. Utilizing the stochasticity of Leonard-Ornstein processes, our suggested strategy encourages the agent to investigate its surroundings.

As a postmodern composer, Bernstein was open about his social activism, yet did not consider his compositional portrayal of female characters as part of that activism. Using discretization as an analysis tool, this thesis explores the melodic contours of male and female songs in West Side Story to show differences in complexity between male and female characterisation. The analysis explores the intervallic relationship between the vocal line and melodic color in relation to the accompaniment harmony, taking into consideration the use of consonance and dissonance. West Side Story is commonly known for its distinct use of the tritone motif and its inherent dissonance. It is evident when reviewing the findings of this study that there is a distinct disparity between male-led and female-led music. The male-led numbers consistently adhere to a dissonant aesthetic with the tritone motif implemented in all of the extracted songs. By contrast, the female songs remain consonant with simple intervallic movements. By examining the results of this study through the lens of Equality Feminism, this thesis finds that Bernstein has simplified the characterisations of the female leads. The thesis further proposes that without cognisant consideration of the compositional portrayal of women, the musical theatre will continue to reinforce gender stereotypes, as evident through this study of Bernstein’s West Side Story. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=music%20theatre" title="music theatre">music theatre</a>, <a href="https://publications.waset.org/abstracts/search?q=gender%20bias" title=" gender bias"> gender bias</a>, <a href="https://publications.waset.org/abstracts/search?q=composition" title=" composition"> composition</a>, <a href="https://publications.waset.org/abstracts/search?q=Leonard%20Bernstein" title=" Leonard Bernstein"> Leonard Bernstein</a> </p> <a href="https://publications.waset.org/abstracts/144878/i-feel-pretty-using-discretization-to-unpack-gender-disparity-in-musical-theatre-a-study-of-leonard-bernsteins-west-side-story" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144878.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">161</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">38</span> Trions in Semiconductor Quantum Dot System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jayden%20Leonard">Jayden Leonard</a>, <a href="https://publications.waset.org/abstracts/search?q=Nguyen%20Que%20Huong"> Nguyen Que Huong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this work, we study the Trion state in a spherical quantum dot of a direct band gap semiconductor with a shell of organic material.

These benefits include task completion rates, overall cost, and better forecasting. Business leaders are often unaware of the challenges that can accompany AI, such as data center costs, access to data, employee acceptance, and privacy concerns. In addition to the benefits and challenges of AI, it is important to practice AI ethics to ensure the safe creation of AI. AI ethics include aspects of algorithm bias, limits in transparency, and surveillance.

Shortest path is one of the most essential measures as it reveals the relations between two nodes in a network.

Many variations to compute top-k shortest paths have been studied. In this paper, we apply an efficient top-k shortest distance routing algorithm to the link prediction problem and test its efficacy.

Thermosalient compounds, colloquially known as ‘jumping crystals’ are promising materials for fabrication of actuators that are also being considered as materials for clean energy conversion because of their capabilities to convert thermal energy into mechanical motion directly. Herein, an organic aminonitrile and its derivatives have been probed by a combination of structural, microscopic and thermoanalytical techniques. Crystals of these compounds were analysed by means of single crystal XRD and hotstage microscopy in the temperature range of 100 to 298 K and found to exhibit the thermosalient effect. We also carried out differential scanning calorimetric analysis at the temperature corresponding to that at which the crystal jumps as observed under a hotstage microscope. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aminonitrile" title="aminonitrile">aminonitrile</a>, <a href="https://publications.waset.org/abstracts/search?q=jumping%20crystal" title=" jumping crystal"> jumping crystal</a>, <a href="https://publications.waset.org/abstracts/search?q=self%20actuation" title=" self actuation"> self actuation</a>, <a href="https://publications.waset.org/abstracts/search?q=thermosalient%20effect" title=" thermosalient effect"> thermosalient effect</a> </p> <a href="https://publications.waset.org/abstracts/34386/thermosalient-effect-of-an-organic-aminonitrile-and-its-derivatives" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34386.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">434</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">33</span> Implementation and Performance Analysis of Data Encryption Standard and RSA Algorithm with Image Steganography and Audio Steganography</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20C.%20Sharma">S.

Cryptographic algorithms scramble the data so that intruder will not able to retrieve it; however steganography covers that data in some cover file so that presence of communication is hidden. This paper presents the implementation of Ron Rivest, Adi Shamir, and Leonard Adleman (RSA) Algorithm with Image and Audio Steganography and Data Encryption Standard (DES) Algorithm with Image and Audio Steganography. The coding for both the algorithms have been done using MATLAB and its observed that these techniques performed better than individual techniques. The risk of unauthorized access is alleviated up to a certain extent by using these techniques. These techniques could be used in Banks, RAW agencies etc, where highly confidential data is transferred.

From the results it is evident that the seismic hazard reaches its maximum level (i.e. PGA≈1g for 475 yr return period) at the Huon Peninsula and southern New Britain regions. Disaggregation analysis revealed that moderate to large earthquakes occurring along the New Britain Trench mainly control the level of hazard at these locations. The open-source computer program OpenQuake developed by Global Earthquake Model foundation was used for the seismic hazard computations.

Elliptic Curve Cryptography (ECC), which allows smaller key length as compared to conventional public key crypto systems, has thus become a very attractive choice for many applications. This paper describes implementation of an elliptic curve cryptography (ECC) encryption engine on a FPGA. The system has been implemented in 2 different key sizes, which are 131 bits and 163 bits. Area and timing analysis are provided for both key sizes for comparison. The crypto system, which has been implemented on Altera’s EPF10K200SBC600-1, has a hardware size of 5945/9984 and 6913/9984 of logic cells for 131 bits implementation and 163 bits implementation respectively. The crypto system operates up to 43 MHz, and performs point multiplication operation in 11.3 ms for 131 bits implementation and 14.9 ms for 163 bits implementation.

This study investigated the process conditions for optimum peroxidase production by Ensifer sp, new ligninolytic proteobacteria with peroxidase production potential. Also, some agricultural residues were valorized for peroxidase production under solid state fermentation. Peroxidase production was optimum at an initial medium pH 7, incubation temperature of 30 °C and agitation speed of 100 rpm using alkali lignin fermentation medium supplemented with guaiacol as the most effective inducer and ammonium sulphate as the best inorganic nitrogen. Optimum peroxidase production by Ensifer sp. was attained at 48 h with specific productivity of 12.76 ± 1.09 U mg⁻¹. Interestingly, probable laccase production was observed with optimum specific productivity of 12.76 ± 0.45 U mg⁻¹ at 72 h. The highest peroxidase yield was observed with sawdust as solid substrate under solid state fermentation. In conclusion, Ensifer sp. possesses the capacity for enhanced peroxidase production that can be exploited for various biotechnological applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=catalase-peroxidase" title="catalase-peroxidase">catalase-peroxidase</a>, <a href="https://publications.waset.org/abstracts/search?q=enzyme%20production" title=" enzyme production"> enzyme production</a>, <a href="https://publications.waset.org/abstracts/search?q=peroxidase" title=" peroxidase"> peroxidase</a>, <a href="https://publications.waset.org/abstracts/search?q=polymerase%20chain%20reaction" title=" polymerase chain reaction"> polymerase chain reaction</a>, <a href="https://publications.waset.org/abstracts/search?q=proteobacteria" title=" proteobacteria"> proteobacteria</a> </p> <a href="https://publications.waset.org/abstracts/76806/optimization-of-process-parameters-for-peroxidase-production-by-ensifer-species" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76806.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">29</span> Challenges in Experimental Testing of a Stiff, Overconsolidated Clay</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maria%20Konstadinou">Maria Konstadinou</a>, <a href="https://publications.waset.org/abstracts/search?q=Etienne%20Alderlieste"> Etienne Alderlieste</a>, <a href="https://publications.waset.org/abstracts/search?q=Anderson%20Peccin%20da%20Silva"> Anderson Peccin da Silva</a>, <a href="https://publications.waset.org/abstracts/search?q=Ben%20Arntz"> Ben Arntz</a>, <a href="https://publications.waset.org/abstracts/search?q=Leonard%20van%20der%20Bijl"> Leonard van der Bijl</a>, <a href="https://publications.waset.org/abstracts/search?q=Wouter%20Verschueren"> Wouter Verschueren</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The shear strength and compression properties of stiff Boom clay from Belgium at the depth of about 30 m has been investigated by means of cone penetration and laboratory testing. The latter consisted of index classification, constant rate of strain, direct, simple shear, and unconfined compression tests. The Boom clay samples exhibited strong swelling tendencies. The suction pressure was measured via different procedures and has been compared to the expected in-situ stress. The undrained shear strength and OCR profile determined from CPTs is not compatible with the experimental measurements, which gave significantly lower values. The observed response can be attributed to the presence of pre-existing discontinuities, as shown in microscale CT scans of the samples. The results of this study demonstrate that the microstructure of the clay prior to testing has an impact on the mechanical behaviour and can cause inconsistencies in the comparison of the laboratory test results with in-situ data. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=boom%20clay" title="boom clay">boom clay</a>, <a href="https://publications.waset.org/abstracts/search?q=laboratory%20testing" title=" laboratory testing"> laboratory testing</a>, <a href="https://publications.waset.org/abstracts/search?q=overconsolidation%20ratio" title=" overconsolidation ratio"> overconsolidation ratio</a>, <a href="https://publications.waset.org/abstracts/search?q=stress-strain%20response" title=" stress-strain response"> stress-strain response</a>, <a href="https://publications.waset.org/abstracts/search?q=swelling" title=" swelling"> swelling</a>, <a href="https://publications.waset.org/abstracts/search?q=undrained%20shear%20strength" title=" undrained shear strength"> undrained shear strength</a> </p> <a href="https://publications.waset.org/abstracts/144267/challenges-in-experimental-testing-of-a-stiff-overconsolidated-clay" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144267.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">146</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">28</span> Integrating Computational Thinking into Classroom Practice – A Case Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Diane%20Vassallo.">Diane Vassallo.</a>, <a href="https://publications.waset.org/abstracts/search?q=Leonard%20Busuttil"> Leonard Busuttil</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Recent educational developments have seen increasing attention attributed to Computational Thinking (CT) and its integration into primary and secondary school curricula. CT is more than simply being able to use technology but encompasses fundamental Computer Science concepts which are deemed to be very important in developing the correct mindset for our future digital citizens. The case study presented in this article explores the journey of a Maltese secondary school teacher in his efforts to plan, develop and integrate CT within the context of a local classroom. The teacher participant was recruited from the Malta EU Code week summer school, a pilot initiative that stemmed from the EU Code week Team’s Train the Trainer program. The qualitative methodology involved interviews with the participant teacher as well as an analysis of the artefacts created by the students during the lessons. The results shed light on the numerous challenges and obstacles that the teacher encountered in his integration of CT, as well as portray some brilliant examples of good practices which can substantially inform further research and practice around the integration of CT in classroom practice. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=computational%20thinking" title="computational thinking">computational thinking</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20citizens" title=" digital citizens"> digital citizens</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20literacy" title=" digital literacy"> digital literacy</a>, <a href="https://publications.waset.org/abstracts/search?q=technology%20integration" title=" technology integration"> technology integration</a> </p> <a href="https://publications.waset.org/abstracts/143616/integrating-computational-thinking-into-classroom-practice-a-case-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143616.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">27</span> E-Consumers’ Attribute Non-Attendance Switching Behavior: Effect of Providing Information on Attributes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Leonard%20Maaya">Leonard Maaya</a>, <a href="https://publications.waset.org/abstracts/search?q=Michel%20Meulders"> Michel Meulders</a>, <a href="https://publications.waset.org/abstracts/search?q=Martina%20Vandebroek"> Martina Vandebroek</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Discrete Choice Experiments (DCE) are used to investigate how product attributes affect decision-makers’ choices. In DCEs, choice situations consisting of several alternatives are presented from which choice-makers select the preferred alternative. Standard multinomial logit models based on random utility theory can be used to estimate the utilities for the attributes. The overarching principle in these models is that respondents understand and use all the attributes when making choices. However, studies suggest that respondents sometimes ignore some attributes (commonly referred to as Attribute Non-Attendance/ANA). The choice modeling literature presents ANA as a static process, i.e., respondents’ ANA behavior does not change throughout the experiment. However, respondents may ignore attributes due to changing factors like availability of information on attributes, learning/fatigue in experiments, etc. We develop a dynamic mixture latent Markov model to model changes in ANA when information on attributes is provided. The model is illustrated on e-consumers’ webshop choices. The results indicate that the dynamic ANA model describes the behavioral changes better than modeling the impact of information using changes in parameters. Further, we find that providing information on attributes leads to an increase in the attendance probabilities for the investigated attributes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=choice%20models" title="choice models">choice models</a>, <a href="https://publications.waset.org/abstracts/search?q=discrete%20choice%20experiments" title=" discrete choice experiments"> discrete choice experiments</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20models" title=" dynamic models"> dynamic models</a>, <a href="https://publications.waset.org/abstracts/search?q=e-commerce" title=" e-commerce"> e-commerce</a>, <a href="https://publications.waset.org/abstracts/search?q=statistical%20modeling" title=" statistical modeling"> statistical modeling</a> </p> <a href="https://publications.waset.org/abstracts/117427/e-consumers-attribute-non-attendance-switching-behavior-effect-of-providing-information-on-attributes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/117427.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">140</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">26</span> Entrepreneurship as a Strategy for National Development and Attainment of Millennium Development Goals (MDGs)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Udokporo%20Emeka%20Leonard">Udokporo Emeka Leonard</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The thrust of this paper is to examine how entrepreneurship can assist in the attainment of the first goal among the MDGs – eradication of extreme poverty and hunger in Nigeria. The paper discusses how national development can be driven through employment creation and wealth generation that can lead to reduction in widespread poverty so as to attain one crucial target, in fewer years. The task before Nigeria is certainly a herculean one; it is, in fact a race against time. However, in view of the clear and present danger that the increasing rate of poverty portends for our democracy and our nation, is a race we must; for it is a time bomb on our hands. The paper has been structured into sections; with the introduction as section one. Section two discusses the concept of entrepreneurship; Section three examines the link between entrepreneurship and economic development, while section four examines the challenges facing entrepreneurship in Nigeria. In section five, measures and recommendations to boost entrepreneurship that can drive economic development that translates into poverty reduction and employment creation in Nigeria are suggested. This work is a literature review with some understanding of current trends and situations. It outlines some of the difficulties facing entrepreneurship in Nigeria as the operating environment, inadequate understanding and skewed incentive. It also makes recommendations on possible ways to significantly reduce poverty in 2015. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=development" title="development">development</a>, <a href="https://publications.waset.org/abstracts/search?q=entrepreneur" title=" entrepreneur"> entrepreneur</a>, <a href="https://publications.waset.org/abstracts/search?q=Nigeria" title=" Nigeria"> Nigeria</a>, <a href="https://publications.waset.org/abstracts/search?q=poverty" title=" poverty"> poverty</a> </p> <a href="https://publications.waset.org/abstracts/41092/entrepreneurship-as-a-strategy-for-national-development-and-attainment-of-millennium-development-goals-mdgs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41092.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">287</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">25</span> An Overview of the Current Status of Lake Jipe and Its Biodiversity Dilemma</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mercy%20Chepkirui">Mercy Chepkirui</a>, <a href="https://publications.waset.org/abstracts/search?q=Paul%20Orina"> Paul Orina</a>, <a href="https://publications.waset.org/abstracts/search?q=Robin%20Abell"> Robin Abell</a>, <a href="https://publications.waset.org/abstracts/search?q=Leonard%20Akwany"> Leonard Akwany</a>, <a href="https://publications.waset.org/abstracts/search?q=Tonny%20Orina"> Tonny Orina</a>, <a href="https://publications.waset.org/abstracts/search?q=Mercy%20Matuma"> Mercy Matuma</a>, <a href="https://publications.waset.org/abstracts/search?q=Rasowo%20Joseph"> Rasowo Joseph</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Lake jipe, a shared water resource between Kenya and Tanzania located at the East African Coast, is under multiple pressures. The lake has receded from 30Km2 to 27.32Km2 due to prolonged dry spells and intensified water abstraction for irrigation and re-route to Mungu ya Nyumba Dam in Tanzania. Agricultural activities have significantly (90%) contributed to the lake levels decline and further affected the lakes’ aquatic biodiversity. Among the most affected are the commercially important endemic fish species of the lake, of which Oreochromis jipe has experienced the greatest decline. Overfishing, use of illegal unreported and unregulated fishing gears, intensified fishing along protected fish breeding areas as well as poor management and uncoordinated conservation efforts have significantly contributed to the decline of fish catches from 348 kg of O. jipe in 2016 to 90 kg daily catches in 2022. Therefore, the lake is on the verge of extinction if no action is taken. This calls for awareness of the significance of the L. Jipe ecosystems and its immediate and long-term benefits. Further, there is a need to revive alternative economic activities, including aquaculture and sustainable agriculture, to offer alternative livelihood to local communities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biodiversity" title="biodiversity">biodiversity</a>, <a href="https://publications.waset.org/abstracts/search?q=ecosystem" title=" ecosystem"> ecosystem</a>, <a href="https://publications.waset.org/abstracts/search?q=conservation" title=" conservation"> conservation</a>, <a href="https://publications.waset.org/abstracts/search?q=fisheries" title=" fisheries"> fisheries</a> </p> <a href="https://publications.waset.org/abstracts/166100/an-overview-of-the-current-status-of-lake-jipe-and-its-biodiversity-dilemma" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166100.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">180</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">24</span> Enhanced Peroxidase Production by Raoultella Species</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ayodeji%20O.%20Falade">Ayodeji O.

Over the years, actinomycetes have been the major peroxidase-producing bacteria. Consequently, other classes of bacteria with peroxidase production potentials are underexplored. This study, therefore, sought to enhance peroxidase production by a Raoultella species, a new ligninolytic proteobacteria strain, by determining the optimum culture conditions (initial pH, incubation temperature and agitation speed) for peroxidase production under submerged fermentation using the classical process of one variable at a time and supplementing the fermentation medium with some lignin model and inorganic nitrogen compounds. Subsequently, the time-course assay was carried out under optimized conditions. Then, some agricultural residues were valorized for peroxidase production under solid state fermentation. Peroxidase production was optimal at initial pH 5, incubation temperature of 35 °C and agitation speed of 150 rpm with guaiacol and ammonium chloride as the best inducer and nitrogen supplement respectively. Peroxidase production by the Raoultella species was optimal at 72 h with specific productivity of 16.48 ± 0.89 U mg⁻¹. A simultaneous production of a non-peroxide dependent extracellular enzyme which suggests probable laccase production was observed with specific productivity of 13.63 ± 0.45 U mg⁻¹ while sawdust gave the best peroxidase yield under solid state fermentation.

In Tanzania, m-Government services usage is in the early stages, and factors that influence its adoption are yet to be known. This study seeks to identify and understand the critical success factors (CSFs) that influence citizens’ behavioural intention (BI) to adopt m-Government services in Tanzania. The study employed the mobile services acceptance model (MSAM) and extends it with external factors relevant in the Tanzanian context. A survey questionnaire was used to collect primary data from users of m-Government services in Dar es salaam and Dodoma cities, and 253 responses were received. Data were analyzed by IBM-SPSS AMOS 23.0 software using structural equation modeling (SEM). The findings of the study indicate that perceived usefulness, trust, perceived mobility, power distance, quality of service, awareness, perceived cost, personal initiatives, and characteristics significantly influence the BI to adopt m-Government services. However, perceived ease of use was found statistically insignificant to predict BI. Furthermore, the interplay between CSFs, discussion on theoretical and practical implications that follow from the results are presented. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adoption" title="adoption">adoption</a>, <a href="https://publications.waset.org/abstracts/search?q=critical%20success%20factors" title=" critical success factors"> critical success factors</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20equation%20modeling" title=" structural equation modeling"> structural equation modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=m-Government" title=" m-Government"> m-Government</a>, <a href="https://publications.waset.org/abstracts/search?q=MSAM" title=" MSAM"> MSAM</a>, <a href="https://publications.waset.org/abstracts/search?q=Tanzania" title=" Tanzania"> Tanzania</a> </p> <a href="https://publications.waset.org/abstracts/131567/an-empirical-study-of-critical-success-factors-for-the-adoption-of-m-government-services-in-tanzania" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/131567.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">149</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">22</span> COVID-19 Pandemic and Disruptions in Nigeria’s Domestic Economic Activities: A Pre-post Empirical Investigation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amaefule">Amaefule</a>, <a href="https://publications.waset.org/abstracts/search?q=Leonard%20Ifeanyi"> Leonard Ifeanyi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study evaluated the disruptions in Nigeria’s domestic economic activities occasioned by the COVID-19 pandemic: a pre and post-pandemic investigation approach. Domestic economic activities were measured with composite manufacturing purchasing managers index (PMI) and composite non-manufacturing PMI. Production and employment levels indices were proxies for composite manufacturing PMI, while business activities and employment level indices were proxies for non-manufacturing PMI. Data for these indices were sourced from monthly and quarterly publications of the Central Bank of Nigeria for periods covering fifteen (15) months before and 15 months after the outbreak of the virus in Nigeria. Test of equality of means was employed in establishing the significance of the difference of means between the pre and post-pandemic domestic economic activities. Results from the analysis indicated that a significant negative difference exists in each of the measures of domestic economic activities between the pre and post-pandemic periods. These findings, therefore, offer empirical evidence that the COVID-19 pandemic has disrupted domestic economic activities in Nigeria; thus, it exerts a negative influence on the measures of the nation’s domestic economic activities. The study thus recommended (among other things) that the Nigerian government should focus on policies that would enhance domestic production, employment and enhance business activities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=COVID-19" title="COVID-19">COVID-19</a>, <a href="https://publications.waset.org/abstracts/search?q=domestic%20economic%20activities" title=" domestic economic activities"> domestic economic activities</a>, <a href="https://publications.waset.org/abstracts/search?q=composite%20manufacturing%20indices" title=" composite manufacturing indices"> composite manufacturing indices</a>, <a href="https://publications.waset.org/abstracts/search?q=composite%20non-manufacturing%20indices" title=" composite non-manufacturing indices"> composite non-manufacturing indices</a> </p> <a href="https://publications.waset.org/abstracts/142632/covid-19-pandemic-and-disruptions-in-nigerias-domestic-economic-activities-a-pre-post-empirical-investigation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142632.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">178</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">21</span> When Sex Matters: A Comparative Generalized Structural Equation Model (GSEM) for the Determinants of Stunting Amongst Under-fives in Uganda</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vallence%20Ngabo%20M.">Vallence Ngabo M.</a>, <a href="https://publications.waset.org/abstracts/search?q=Leonard%20Atuhaire"> Leonard Atuhaire</a>, <a href="https://publications.waset.org/abstracts/search?q=Peter%20Clever%20Rutayisire"> Peter Clever Rutayisire</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The main aim of this study was to establish the differences in both the determinants of stunting and the causal mechanism through which the identified determinants influence stunting amongst male and female under-fives in Uganda.

Specifically, studies in Uganda indicate that being a male child is positively associated with stunting, while being a female is negatively associated with stunting. Data for 904 males and 829 females under-fives was extracted form UDHS-2016 survey dataset. Key variables for this study were identified and used in generating relevant models and paths. Structural equation modeling techniques were used in their generalized form (GSEM). The generalized nature necessitated specifying both the family and link functions for each response variable in the system of the model. The sex of the child (b4) was used as a grouping factor and the height for age (HAZ) scores were used to construct the status for stunting of under-fives. The estimated models and path clearly indicated that the set of underlying factors that influence male and female under-fives respectively was different and the path through which they influence stunting was different. However, some of the determinants that influenced stunting amongst male under-fives also influenced stunting amongst the female under-fives. To reduce the stunting problem to the desirable state, it is important to consider the multifaceted and complex nature of the risk factors that influence stunting amongst the under-fives but, more importantly, consider the different sex-specific factors and their causal mechanism or paths through which they influence stunting. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=stunting" title="stunting">stunting</a>, <a href="https://publications.waset.org/abstracts/search?q=underfives" title=" underfives"> underfives</a>, <a href="https://publications.waset.org/abstracts/search?q=sex%20of%20the%20child" title=" sex of the child"> sex of the child</a>, <a href="https://publications.waset.org/abstracts/search?q=GSEM" title=" GSEM"> GSEM</a>, <a href="https://publications.waset.org/abstracts/search?q=causal%20mechanism" title=" causal mechanism"> causal mechanism</a> </p> <a href="https://publications.waset.org/abstracts/149264/when-sex-matters-a-comparative-generalized-structural-equation-model-gsem-for-the-determinants-of-stunting-amongst-under-fives-in-uganda" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149264.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">140</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">20</span> Prediction of Distillation Curve and Reid Vapor Pressure of Dual-Alcohol Gasoline Blends Using Artificial Neural Network for the Determination of Fuel Performance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Leonard%20D.%20Agana">Leonard D.

Distillation curve and Reid vapor pressure were predicted using artificial neural networks (ANN) with macroscopic properties such as boiling points, RVP, and molecular weights as the input layers. The ANN consists of 5 hidden layers and was trained using Bayesian regularization. The training mean square error (MSE) and R-value for the ANN of RVP are 91.4113 and 0.9151, respectively, while the training MSE and R-value for the distillation curve are 33.4867 and 0.9927. Fuel performance analysis of the dual alcohol–gasoline blends indicated that highly volatile gasoline blended with dual alcohols results in non-compliant fuel blends with D4814 standard. Mixtures of low-volatile gasoline and 10% methanol or 10% ethanol can still be blended with up to 10% C3 and C4 alcohols. Intermediate volatile gasoline containing 10% methanol or 10% ethanol can still be blended with C3 and C4 alcohols that have low RVPs, such as 1-propanol, 1-butanol, 2-butanol, and i-butanol.

Online support programmes may prove effective in addressing the mental health and well-being needs of family carers. This study sought to test the acceptability of a newly developed online support programme for carers of people with intellectual disabilities called Carers-ID. Methods A sequential mixed-methods explanatory design was utilised. An adapted version of the Acceptability of Health Apps among Adolescents (AHAA) Scale was distributed to family carers who had viewed the Carers-ID.com intervention. Following this, participants were invited to take part in an online interview. Interview questions focused on participants’ experiences of using the programme and its acceptability. Qualitative and quantitative data were analysed separately and then brought together through the triangulation protocol developed by Farmer et al (2006). Findings: Seventy family carers responded to the acceptability survey, whilst 10 took part in interviews. Six themes were generated from interviews with family carers. Based on our triangulation, four areas of convergence were identified, these included, programme usability and ease, attitudes towards the programme, perceptions of effectiveness, and programme relatability. Conclusions: In order to be acceptable, online interventions for carers of people with ID need to be accessible, understandable and easy to use, as carers time is precious. Further research is needed to investigate the effectiveness of online interventions for family carers, specifically considering which carers the intervention works for, and for whom it may not. <p
