In this paper, a wireless power transmission (WPT) using resonant magnetic coupling for mobile phone charger is presented. Solar energy was used as the energy source to address the scarcity of non-renewable energy sources and tackles the constraints of wired charging technology such as lack of universal electrical standard, untidiness and inconvenience of wires and wires' wear and tear. The system includes PV panels and battery, oscillator, transmitting coil and receiving coil and rectifier. Proteus 8.1 was used to simulate before implementing in the hardware. The resonant magnetic coupling resonated at 800 kHz ± 10 kHz. The maximum distance to charge a mobile phone was 4 cm at 3.7 V. All the objectives are achieved within the limited time frame. The significance of the project can help to eradicate the use of wires and the need of power plugs. The
future research includes the study of efficiency, coil design, system with multiple loads.

The aim of the study was to assess the knowledge and compliance level of Edo State Sanitation Management Laws among traders in Benin metropolis. In the study, five research questions were raised and three were hypothesized. This study used the descriptive survey research design to carry out the study.

A self- constructed questionnaire was used for the study and the instrument was validated. To ascertain the reliability of the instrument, test re-test reliability method was used. A pearson correlation coefficient score of 0.78 was observed thus, the instrument is reliable. Data collected were analyzed using descriptive
statistics of frequency count and percentages.Hypotheses were tested using pearson correlation and one way ANOVA. It was discovered in the study that majority of the respondents have moderate knowledge towards Edo State Sanitation Management laws; majority of the respondents indicated that they always dump refuse in gutter whenever they are not been watched or monitored; dropped refuse in open space when there is no waste bin; take interest in picking garbage, sometimes wastes around
my premises. There is a significant weak and negative relationship between knowledge and compliance with Sanitation management laws among traders in Benin metropolis. Educational background influenced the compliance of sanitation management laws of traders in Benin metropolis. Based on the findings of the study, the researcher recommended that there is need for proper sensitization of the traders in order to improve their knowledge towards the environment
sanitation laws amongst others.

Giardiasis is a disease of public health importance, a common cause of acute and chronic human diarrheal. In some developing countries, infection and mortality rates among young children can be quite high. This study was carried out to determine Giardia lamblia infection among children in rural and urban areas in Benin City, Edo State, A comparative study was done, using the microscopy method and ELISA technique, 288 primary school children consisted of (194) males and (94) females were enrolled in this study, Stool specimen was collected from each participant into a sterile universal bottle and sent for analysis to the laboratory department of City of Hope Medical Centre, Benin city. The age of participants ranged from 6-14years. A well-structured questionnaire bothering on the bio-data and socio-demographic characteristics was administered on each participant prior to the collection of Specimen. Informed consent was obtained from the parent or guardian of each participant. The stool specimens were analyzed using microscopy and ELISA technique. A prevalence of 5.6% of Giardia lamblia infection was observed among children in the Study Areas. Comparative studies of the microscopy method and ELISA techniques showed a p-value of < 0.05 (0.001) which was significant. There was a significant difference in the age group 10-11 years old presenting with the highest prevalence of 13.7% in comparison to other age groups with p-value < 0.05 (0.014). Hand hygiene was highly prevalent (12.5%) with p-value <0.05(0.000) which was significant, which showed that those who observed poor hand hygiene are with the high odds of being infected than those who practice good hand hygiene. Epidemiological factors such as Residential locations, settlement type, type of toilet, proximity of kitchen to toilet facility, diarrhoea, and Food source significantly affected the prevalence of G. lamblia infection. Increased Awareness, personal hygiene and good sanitary practices, particularly among mothers and children, should be encouraged as this would curb the spread of giardiasis. ELISA with sensitivity of 95% to 100% and specificity over 90% when compared withdirect microscopy provides a relevant alternative method to the routine ova and parasite examination in diagnosing giardiasis. Based on this, detection of giardiasis should not solely be based on microscopy; more effective methods such as ELISA could be employed.

the experiment was conducted to determine the yield, physical and chemical composition of leaf protein concentrates and bagasse obtained from oil palm leaf using three different processing methods. The process of extraction were heat coagulation, acid coagulation, and alum precipitation methods. The leaf protein concentrates and bagasse obtained were further analysed for their chemical and mineral compositions. The yield of LPC and bagasse obtained from acid coagulation, alum precipitation, and heat precipitation were comparable. But, the yield of OLPC was not significantly (p>0.05) different in the acid and alum processing methods, but was significantly (p<0.05) different for the heat processing method. Result, from the chemical analysis shows that the CP and EE of acid coagulation method were significantly (p<0.05) different from alum and heat processing methods. At the same time, the MC and NFE of OLPC for heat were significantly (p<0.05) different from alum precipitation method and acid coagulation method. From the results obtained from this study, Oil palm leaf protein concentrates obtained using heat coagulation, acid coagulation and alum precipitation methods were comparable but heat coagulation would be preferable as a result of its high Ca (633.0), Cu (15.67), Mn (66.83), Zn (108.77), Na (3.46), Mg (501.63), P (417.67), Fe (154.30)
and Cl (1.307) values.

Boko Haram is a radical Islamist movement shaped by its Nigerian context and reflecting Nigeria’s history of poor governance and extreme poverty in the north. The movement is unique in that it combines a sectarian, radical Islamic agenda with violence. Its stated goal is the establishment of a sharia state, but it shows little interest in actually governing or implementing economic development. It is based on the fundamentalist Wahhabi theological system and opposes the Islam of the traditional northern Nigerian establishment, which is broadly tolerant. Boko Haram, as an extension of the Maitatsineuprising in 1970s and 1980s ,it is not in doubt that Boko Haram is part of the unaddressed issues on religion which the Maitatsine had attempted to raise in the northern parts of the country, starting from Kano more than three decades ago. An offshoot of Islam called the
Yan’ tatsine’ violently rebelled against the authorities and non-members.1 These radical Muslims estimated between 3000 and 5000 were inspired by Mohammed Marwa, an Islamic scholar who migrated from the town of Marwa in
Northern Cameroun to the city of Kano in 1945. Boko Haram and its more radical splinter, are steadily expanding their area of operations. Kidnapping has become a major source of revenue and is widespread, while attacks have occurred in Lagos and Kano. The government’s response has been to treat Boko Haram as a part of the international al- 8 Qaeda movement. Security service abuses are likely a driver of some popular support foror acquiescence to Boko Haram. The struggle between the government and Boko Haram has dire humanitarian consequences. Many people have been internally displaced in
northern Nigeria and many refugees have fled to neighboring countries.

Fuzzy inference systems (FIS) are particularly suited for aggregating multiple data to feed multi-variables decision support systems. Moreover, wine quality is a complex concept that refers to the simultaneous achievement of optimal levels in many parameters, thus single wine attributes spatial data are not adequate to define wine suitability for a specific end use. The aim of this study was to design and implement a fuzzy inference system on wine quality prediction using physiochemical parameters from wine dataset. The proposed system adopted the conventional fuzzy inference system which consists of four major components which are: knowledge acquisition, knowledge base, fuzzy inference engine and a user interface. The dataset is fuzzified into variables that were used to develop rule for the classification of wine quality. The fuzzy inference system followed three transformation stages; fuzzification, rule based and defuzzification processes. The model was implemented using C#, programming language and MYSQL as the relational data base management. The model was developed on window Microsoft system
