Mbata, Raymond; Mr. Anthony, Enwin DUrbanization is the new trend in human migration and population growth. In the quest for good jobs and economic growth, sustainable cities and communities and ongoing implementation of the sustainable development goals (SDG) 2030, building professionals, government, key decision-makers and stakeholders are sensibly adapting to the rapid growth in urbanization. Urban growth expansion also comes with its challenges which could result in over-concentration, overconsumption and unhealthy competitions etc. New policies, frameworks and strategies are needed for mitigation and total prevention. This research paper presents a new model for the approach of mixed-used development. It reveals how a mixed-used development strategy can be used to reshape a city and attain sustainable urbanization. The Authors did a study of Daning neighbourhood, china which could serve as case study for modern day mixed-used development. This paper further entails the history and importance of mixed-use facility and development for a successful urban migration, revitalization and redevelopment.
Potentiation of FSH-like effects of the extracts and fractions of Senecio biafrae (Oliv. & Hiern) J. Moore (Asteraceae) by a subthreshold dose of PMSG [PDF]
Landry LIENOU LIENOU, Marie Stephanie CHEKEM GOKA, Gildas TETAPING MBEMYA, Nathalie JIATSA DONFACK, Anne Rosalie NGANE NGONO, Phélix Bruno TELEFOThe FSH-like effect of Senecio biafrae can be potentiated by reproductive hormones to accelerate the awakening of the Hypothalamus-Pituitary-Gonad axis in immature animals. This research evaluated the synergistic effect between Pregnant Mare Serum Gonadotrophin (PMSG) and the extracts and fractions of S. biafrae (EFSb) in boosting sexual maturation. Various PMSG doses were administered to immature female rats during 5 consecutive days. Its highest dose without effect on ovary and uterus was co-administered with 4, 8, 32, 64 and 128 mg/kg doses of aqueous, ethanol and methanol/methylene chloride extracts as well as hexane, ethyl acetate and n-butanol fractions of S. biafrae during five days. Ovarian and uterine masses, proteins and cholesterol, serum FSH, LH, estradiol, progesterone levels and ovarian follicle numbers were evaluated. The subthreshold value of PMSG was 0.011 UI/rat/day. Its co-administration with EFSb led to a significant drop (p<0.05) in ovarian mass, but to an increase tendency in ovarian proteins and cholesterol. Uterine mass and proteins significantly increased in almost all treated animals. FSH, LH and estradiol significantly increased while progesterone was decreasing. Primary and secondary follicle presented high counts in almost all treated groups (p<0.05). Co-administration of EFSb and PMSG led to successful stimulation of the reproductive axis.

JOYREM J. ONDRADA*, MAURICE D. JIMENEA, ANA HAZEL D. BARISON, JERAH MAE B. GRANDE, ANABELLE J. VILLAR, AIRENE J. FERNANDEZ, JASON A. IBAŇEZ, FRANCIS D. PABONThe study focused on the phytochemical screening and brine shrimp lethality assay of the Billy goat weed (Ageratum conyzoides Linn.). Dried leaves of the A. conyzoides were prepared as a sample for phytochemical composition analysis. The ethanolic crude extract of A. conyzoides was obtained for phytochemical screening using the test tube method. The same crude extracts were used for the detection of cytotoxic activity using brine shrimp lethality assay (BSLA) against brine shrimp eggs (nauplii). The phytochemicals detected were alkaloids, saponins, glycosides, flavonoids, phenols, terpenes, coumarins, steroids, tannins, cardiac glycosides, and resins. These phytochemicals were expected to possess pharmacological activities, anti-allergic, anti-oxidant, anti-inflammatory, and anti-bacterial properties. The toxicity level was found out to be active with LC50 of 56.23µg/mL. Different solvents are explored in order to optimize the phytochemical screening and cytotoxic level of Billy goat weed (Ageratum conyzoides Linn.).
AN ASSESSMENT OF THE IMPACT OF SOCIAL MEDIA USE IN THE WORKPLACE ON PUBLIC SECTOR SERVICE DELIVERY: A CASE OF ZIMBABWE GOVERNMENT DEPARTMENTS IN HWANGE DISTRICT [PDF]
Bernard NgwenyaZimbabwe has witnessed a phenomenal growth in social media use over the past few years. The use of these social networking sites has infiltrated the workplace, with a potential impact on employee productivity and work quality. Employees are spending more time on social media engaging in non – work-related activities. The study sought to assess the impact of social media use in the workplace on service delivery in the public sector. Specifically, the study set out to establish the extent of social media use in the workplace by public sector employees, and examine policy initiatives that the respective departments were taking on the use of social media in the workplace. The study was conducted in Hwange district, Zimbabwe, with a population frame of 351 public sector employees. Data were collected using the questionnaire and interview schedule and analysed using Microsoft Excel both qualitatively and quantitatively. The study found out that the civil servants in Zimbabwe visit social media sites while at work engaging in non-work-related activities, mainly through their own devices. None of the public sector departments had a social media policy in place to regulate the use of social media in the workplace. The frequent use of social media in the workplace by government employees compromises public sector service delivery. The study recommends that the Zimbabwe government should come up with a social media policy to guide the use of social media in the workplace.
Public Debt and Incidence of Poverty in Sub-Saharan Africa: The role of Institutional Quality [PDF]
Abdullahi Sani, Adamu YahayaAbstract
The continuous accumulation of public debt and ever increasing incidence of poverty in Sub-Saharan African (SSA) has been investigated by various researchers. This study aims at investigating the role of institutional quality in the public debt, incidence of poverty relationship. Using the Generalized Method of Moment (GMM) approach on a sample of 42 SSA countries, the link between public debt and incidence of poverty was examined over the period 2011 to 2019. The findings of this study revealed that the relationship between the public debt and Household Final Consumption Expenditure Per capital is negative, and this shows that public debt accumulation is one of the leading causes of poverty in SSA. However, the result of the interaction term of public debt and institutional quality confirms that this negative relationship can be averted or even reversed if the quality of the institutions improves in the region. This indicates that, while public debt accumulation aggravates the incidence of poverty, such an appalling trend can be reverted or even prevented. The study therefore, recommends the need for governments to take a determined stand of not only minimizing public debt accumulation but also ensuring comprehensive improvement of institutional qualities to alleviate the incidence of poverty in SSA.
HERITAGE FRUITS CONSUMED BY THE PEOPLE OF THE NYONG AND KELLE DIVISION: CAMEROON [PDF]
Bayi Joseph, Ngah Esther, Megueni ClautildeThe present work aims to show the heritage fruits consumed by the people of the Nyong and Kelle division. Heritage fruits are fruits which come from an area and are consumed by the people of this area for many years; these fruits are bequeathed to the next generation. A systematic survey was carried out to identify heritage fruits in the markets, crop farms and forest of the study area. With modernization heritage fruits are been abandoned by the present generation in the way that if nothing is done some of these heritage fruits will disappear from the consumption chain if they are not bequeathed to the next generation, this will lead to the loss of food identity and acculturation of the population of the study area. In all 34 heritage fruits were encountered and they fell under 21 botanical families according to the Linear Angiosperm Phylogeny Group III classification. Nine of these fruits were not consumed directly but are dried and transformed into spices to season meals. 90 % of these heritage fruit had a market value and are a source of income to this population. The physico- sensory properties of these fruits were given with the largest part of fruit having a humid nature; the color of the pulp was reddish, brownish, greenish and whitish. Most of the fruit tasted sweet, the large part of the shape was ovoid. Some of these heritage fruits trees are used in folk medicine by the population to relief from certain illnesses. The present study promotes heritage fruits, sustainable development and empowerment of the rural population.
How Global Leaders Can Actively Shape the Future by their Present Actions and Choices [PDF]
Kehinde David FolarinABSTRACT
Today’s global organizations exert much more influence than they wielded just a few decades ago. In a relatively short period of time, the world marketplace has undergone industrialization, mechanization, urbanization, and a technology boom. On the heels of these technological advancements, we have witnessed the deterioration of moral and ethical values, corruption, financial irresponsibility, and disregard for social responsibility in the United States and in other countries. In juxtaposition with these changes stakeholders; investors, individuals, environmental groups, expectations of organizations have greatly expanded to necessitate the need for universal truths and morality as the foundation of business practices. This paper discusses the driving forces affecting the future of global organizations, how important transformational leadership driving strategic thinking and planning based upon the foundation of biblical principles will transform the global organization into one of great moral value and sustainability.
Keywords. Industrialization, urbanization, technology, mechanization, global organizations, technological advancement, transformational leadership, biblical principles, moral values, and sustainability.
Leaders- Followers Communication [PDF]
Kehinde David FolarinABSTRACT
Communication has always been one of the greatest tools for people to interact with each other. Taking into consideration that the easiness of interacting with people all over the world was never easier, one can see that, today, we have more different channels, languages, and ways of how to communicate than ever before.
But globalization also means that our communication and understanding are changing. Globalization asks for adaptation of our old and beloved perception of communication, and creates synergies of our understanding, coming from all over the world. As the world is moving and changing, we are moving and communication plays an important role for us, to recognize and understand what is actually going on around us. Organizations are facing confused employees and leaders do not know how to handle their followers. This change is the reason why communication so to say is a pillar for a world of interacting people. I see great importance, causing threats, and at the same time, I see opportunities for improvements with this pillar, which organizations, individuals, as well as groups, should be aware of. To understand the necessity of this pillar, this project tries to analyze their importance by relating and presenting their effects to and on people’s interactions. As it is a project within the field of business and leadership it will mainly deal with the perspectives of organizations and the people involved.
Furthermore, it will be tried to narrow down the topic, even more, going into detail of internal communication of the modern world, meaning the younger generations using all new methods of communication.

STUDY OF THE EFFECT OF ANNEALING TEMPERATURE ON Zn DOPED TiO2 NANOCRYSTAL STRUCTURES PREPARED BY SOL-GEL METHOD [PDF]
Rabin Siwakoti, Dr. Suresh Kumar Dhungel, Dr. Surendra Kumar Gautam, Sanjit karki, Kebindra Shrestha, Prashanta sharmaThe advancement of TiO2 has always been serious concern for the better performance of photo- catalytic behavior even in unsuitable intensity of light. For this issue, the doping of TiO2 with transition metals has attracted serious attention for the researchers. Zn2+ metal ion is more effective among other transition metal ions such as Fe2+, Mn2+, Cu2+, Zn2+ etc., because the ionic radii of Zn2+ (0.074 nm) and of Ti4+ (0.075 nm) are similar to each other and hence, it is easier for substituting Ti4+ ion by Zn2+ ion without destroying crystal structure. For the preparation of zinc ion doped titania nanoparticles very useful Sol- Gel synthesis tool has been used during this research. Zn2+ ion was doped on titania varying the concentration of Zn2+ (from 0.1 M to 0.5 M). The prepared samples were characterized by XRD and SEM tools. The prepared samples were found to be having 7 nm average grain size after the determination of sample diameter by applying Debye- Scherrers formula. While the XRD data for specific sample (A2), of which SEM analysis was carried out, was found to be 12.32 nm and was supported by the information derived from SEM (11.90 nm). On comparison between annealing temperature and size of nanocrystals, it was found that on increasing annealing temperature the crystal size also increases gradually. The variation in annealing temperature above 5000C results in the transformation of anatase TiO2 crystals into rutile crystals.

FARMERS COMPETENCE AND CHALLENGES IN FOOD CROP MANAGEMENT IN THE NDOP PLAIN [PDF]
Kometa Sunday Shende and Tafuh Desmond ForbahAgriculture is one of the sectors with the potentials to enhance people’s standard of living. Severe hunger and poverty affects nearly one billion people around the world and as a result, the demand for food necessitates improvement in planning and management techniques of food crop production. Given that food crop cultivation remains crucial for livelihood sustenance, management techniques by farmers are largely unsustainable. With continuous increase in population, the demand for food crops remains a threat to the community as the inputs of farmers into the farms does not reflect their output in the Ndop Plain. The supply of food crops is becoming unsecured in view of the post-harvest losses incurred by farmers. Farmers Competence in Food Crop Management holds promises to increase food crop production and minimise post harvest losses. This holds that farmers success in food crop management requires a certain level of knowledge, skills, attitudes and experience acquired through formal and informal training. The study intends to investigate farmers’ competence and challenges in food crop management in the Ndop Plain. The study makes use of primary and secondary data collection in which purposive random sampling was used in administering the questionnaires. Primary sources of data collection used in the study include field observation, interview and administration of questionnaires. Direct interviews with resource persons such as the Divisional Delegate of Agriculture and Rural Development, the director of UNVDA, the Mayor of Ndop Centre, Babessi and Balikumbat Councils and the director of Rural Development Consultancy helped to identify farmer’s competency in pre and post-harvest management activities that ensures food security in the Ndop Plain. A total of two hundred and fifty three (253) questionnaires were randomly sampled to household directly or indirectly involve in the agricultural sector in the Ndop Plain. With a total agricultural population of 141757 farmers and a sample size of 14176, a sample population size was selected according to the agricultural population of each village in the Ndop Plain. In the Ndop Plain, farmers competency was determined by evaluating farmers level of education, skills in food crop management, experience in food crop production and attitudes towards training in food crop management. The Factor Analysis reveal that challenges of farmers’ competence in food crop Management is strongly significant by contributing 63% drawbacks in farmers’ livelihood in the Ndop Plain. The study concluded that challenges of farmers competence in food crop Management account for poor food crop production in the Ndop Plain. The study recommends that effective implementation of innovative programs, farmers’ education and sensitization on environmental changes and agrarian development programs vis-a-vis food security should be created at all levels.
TURBOCHARGER OPTIMIZATION FOR GENSET ENGINE [PDF]
Omprakash Yadav (M.Te ch Scholar), Ajay Kumar (Asst. Professor LIET Alwar), Dr. Manvijay Singh (Prof. LIET Alwar)In general, the internal combustion engine requires air and fuel as input and gives mechanical power output. The air quantity depends on the engine cylinder size and volumetric efficiency. Limited power can be generated from a particular size of engine due to limitation of air availability for combustion. Turbocharger is required to increase air quantity for same size of engine. Turbocharging technique is more and widely employed on CI and SI internal combustion engines to improve performance of same size of engine. Diesel engine operates with excess air and can be operated with higher compression and peak firing pressure. SI engines compression pressure limitation due to knocking. Turbocharger is more advantageous for CI engines to increase power and improve fuel consumption and exhaust emissions. Turbocharger is a significant contributor to meet fuel consumption and stringent emission norms. Turbocharger optimization required a systematic approach for best optimum results. Selection of a proper turbocharger is very important for engine performance and emissions.

Factors in security agents’ homicide: Implications crime management in Nigeria. [PDF]
Eraye Christopher MICHAELThe study explores homicide among security agents and its obvious implications on crime prevention and control in Nigeria. The rate of gruesome and violent death of security persons is becoming alarming. It was uncovered that violent challenge from armed robbers and kidnappers, mob action an inter-agency clashes were the dimension of security agents homicide. The study further revealed recklessness and carelessness, weak intelligence-gathering capacity and armed proliferation are some of the factors that promote security agents homicide. The upsurge in security agents homicide has resulted in the demise of some skillful and experience officers and reduction in security persons which affect crime management. It was recommended that there is need for security organizations to ensure that officers are properly train on intelligence-gathering, technological and other facilities required for intelligence-gathering should be provided for the personnel. There should be a strong legislation mandating all security agencies to share intelligence information with others Security agencies, that government must not relent in its effort to provide essential facilities such as arms and ammunitions and other modern crime fighting equipment for security persons this will inevitably improve security agents’ efficiency and effectiveness in crime prevention and control.
Comparative Analysis of Three methods for Inverse problems applied in Imaging [PDF]
Viateur IRAKARAMANowadays, a core technology for solving image processing problems such as denoising and deblurring is regularization. Image pro-cessing is an interdisciplinary research area which has profound applications in many areas of science, technology, engineering and medicine. We plan to present a comparative analysis of three methods for commonly used regularization method namely total varia-tion regularization. The three methods are the well-known Split Bregman algorithms, the Alternating Direction Method of Multipliers and the Rudin Osher Fatemi denoising model on the graph (ROF model on the graph) which is very recent. The analysis is performed through experimental results on multiple test images both synthetic and real. We observe that they are all comparable in many cases; however the ROF model on the graph achieves a prescribed tolerance in fewer iterations than the other methods.

IMPACTS OF PARTICIPATORY FOREST MANAGEMENT ON RURAL HOUSE-HOLDS’ LIVELIHOODS: THE CASE OF BONGA PARTICIPATORY FOREST MANAGEMENT PROJECT, SOUTH WEST, ETHIOPIA [PDF]
Participatory Forest Management (PFM) is a typical forest management approach that critically requires the active participation of the local community for the wise exploitation of forest products while protecting the forest from any unplanned intervention. PFM started in Ethiopia in the mid-1990s and proved to be successful practice in benefiting the local people and improving forest conditions. PFM has been practiced in Bonga forest, South West Ethiopia. There are no adequate site-specific empirical studies on the effectiveness of PFM approaches through the use of rigorous and scientifically valid impact assessment methods in this study area. This paper assessed the impacts of the PFM on the livelihoods of rural households’ of PFM member of Bonga PFM sites. A total of 269 households, 141 from PFM member and 128 from Non-PFM members were randomly selected for household survey to collect socio-economic data. Key informant interview and focus group discussion was also employed. The collected cross-sectional data were analyzed using the propensity score matching (PSM) model. The result revealed that PFM increased the forest income of PFM members by 3466.60 ETB and the number of consumption assets by 1.25. PFM had also decreased livestock holding in TLU by 1.44 and household income from the crop by 4827.68 ETB. We conclude that PFM has a positive impact on rural households’ livelihoods and recommend that other livelihood strengthening interventions should be integrated with PFM to enhance the performance of PFM.

VOLTAGE STABILITY STUDIES OF PHED IN IKWERRE ROAD DIOBU AXIS OF PORT HARCOURT, NIGERIA [PDF]
Albert Ehimhen Eigbe, Prof. Christopher Okwuchukwu Ahiakwo, Dr. Sepiribo Lucky BraideIn this research, numerical iterative techniques were used to conduct voltage stability analysis of Port Harcourt Electricity Distribution (PHED) in Ikwerre Road, Diobu axis of Port Harcourt in Nigeria, with the view of addressing the system overload on the power system components such as transformer, undersize cable/conductor bus bar feeder links, etc. The application of reactive power support by capacitor compensation can help minimize the cost of distribution loss in the power supply to Ikwerre Road, Diobu axis Port Harcourt. The objectives focus on the following areas: compensation of capacitor bank before penetration to improve the system reliability, penetration of voltage stability indices values with different Distributed Generator (DG) size, increasing the DG size on voltages of dif-ferent load point, increasing the DG size of power flow with different DG and without DG size, increasing the DG size as a result of maximum loading point, increasing the DG size on the penetration level from the Load, increasing the DG size on power losses. The tendency of studying the analysis of voltage instability in power system operation and planning is to strongly identify, monitor, plan, and predict the gradual increase in power system demand and voltage profile of the Ikwerre Road, Diobu axis of Port-Harcourt. Elec-trical Transient Analyzer Program (ETAP) software was used for the simulation of the system. The simulation of the existing system case shows inequality and overload conditions on the system components. From the simulation, it showed that increasing the size of DG unit on power flow causes a reduction in real power generated by The Power Holding Company of Nigeria (PHCN) due to the in-stalled DG unit at Gambia street, Port Harcourt. Also, the maximum value of the loading parameter of the power system increased when the size of DG increases. Maximum load ability changes from 3.1217 to 4.0125 when the DG generates 60% from the load, thus the increase is by 0.8908. The increment in the value of Maximum load ability is due to the install DG. The results also showed that Reduction in the cost of power distribution and consumption in the network improves the system voltage profile and power system quality.
Integrated Nutrient Management in Rice- A Critical Review [PDF]
Shamal S. Kumar, Ashraf Sultan, Adiba Ejaz, J Radha Krishna4Rice (Oryza sativa L.) is a staple food for nearly half of the world’s population. Being an agricultural commodity it is the third-highest worldwide produced commodity after sugarcane and maize. At present the current world population is 7.3 billion which is expected to reach 8.5 billion by 2030. As a result the global demand towards grain is projected to double but the challenge to achieve even higher rice production level still remains. In order to meet the global demand of the growing population, rice production must be substantially increased with the adoption of the concept of Integrated Nutrient Management (INM) which must be given top-most priority. Integrated nutrient management is the maintenance or adjustment of soil fertility, plant nutrient supply to an optimum level for sustaining the desired productivity through optimization of the benefits from all possible sources of plant nutrients in an integrated manner. This concept is of very much importance since it involves the use of inorganic fertilizers along with organic sources that are applied to soil for increasing the quality and yield of plants in a sustainable manner without harming the natural ecosystem. With the use of integrated nutrient management in rice it has increasingly improved the overall respondents on the grain crop which leads to maximum growth characteristics and yield attributes.

1) Innocent MUHIMBA , 2) Dr. Emmanuel MUVANDIMWE, 3) Msc. Michael HABTUABSTRACT
Early ANC attendance promotes early detection and treatment of complications which result in proper management during delivery and puerperium. The research aimed to examine the factors behind late ANC services among pregnant women in Rwanda. This research was a cross-sectional study using a mixed research approach. The study population was included pregnant women in the age group of 15–49 years coming for ANC services from February to March 2020 in the seven health centers from Mugonero District Hospital catchment area. For quantitative data, a sample size of 140 respondents were selected using a two-stage randomized cluster sampling procedure from the study population. For qualitative data, 23 key informants were involved in the research and 8 FGDs and were selected using purposive sampling technique. Data were collected through structured questionnaire from quantitative data and through interview guide for qualitative data. Quantitative data were coded and analyzed using SPSS version 21 while qualitative data were transcripted from the key informants and FGDs for their deep understanding. The research findings revealed that the prevalence of late ANC utilization was 57.1%. The multivariate analysis showed that ANC late was 2.1 times higher among pregnant women with primary education level (AOR = 2.1, 95% CI: [1.32-2.60]), 1.85 times higher among housewives compared to mothers who were employed (AOR = 1.85, 95% CI: [1.36-3.82]), 1.90 times higher among mothers who paid themselves transport cost (AOR
= 1.90, 95% CI: [1.25-2.18]), and was 2 times higher among mothers who previously attended
ANC and failed to be served compared to well served mothers when previously attended ANC services (AOR = 2.0, 95% CI: [1.82-3.16]) keeping other variables constant. Qualitative result from the seven FGDs indicated that the main barriers for ANC utilization were the absence of their husbands, fear to go for ANC while pregnancy not visible, payment for laboratory tests, long distances to go to health facility, waiting time at health facility while waiting for ANC services, all of these were declared as the factors limiting the pregnant mothers to attend in time, while for the sources of information on antenatal care services, all groups pinpointed the community health workers and health facility staff. The key informants suggested that health care providers have to increase the number of health care providers, field outreach by approaching women for ANC, training of workers on ANC, health education to women about antenatal services, presence of various partners in ANC related services and avail free of charge for ANC service. The district health offices should work closely with CHWs on creating awareness about the benefits of early attendance of ANC both for the mother and the fetus. It is also better to make the service closer to mothers who need to travel long distances. The researcher recommended to the Ministry of Health to strengthen health education on ANC among women to guarantee that the late utilization of ANC service is eliminated.
