Driving in urban centers and neighborhoods at high speed without regard to safety of the inhabitants brought about the emergence of the use of speed bumps and other traffic devices. Road bumps play a crucial goal in enforcing speed limits, thereby
preventing over speeding of vehicles. The use of this device overtime had resulted in series of debate worldwide. While some
are complaining of the inconvenience caused by this device, others are calling for more of this device. This study therefore seek to investigate the use of speed bumps on Nigeria highway with specific reference to Warri-Sapele road, Warri, Delta State.
Using quantitative research method, 50 units of questionnaires were designed and administered to drivers, motorist and residents at various reference points on the road section to sought information about the effectiveness of the devices. measurement of the height, width, length and spacing of the device were carried out with the aid of equipment in Geomatics engineering and this data were compared to the city of Bakersfield, California standard for speed bump parameter. The result shows that 84.4% of the existing speed bumps were of spacing below the LATM standard of 60-90(m), 26.7% had width less than the accepted value of 300mm and 100% had height exceeding the standard of 60mm. The result of the speed bumps parameters shows that the bumps were built with no recourse to specification as the height, width, length and spacing keeps changing from one bump to the other due to its instantaneous demand.

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 a 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.

Does class classification of students affect the study habits of public secondary school students in Oredo Local Government Area of Edo State? How does the type of school affect the study habits of public secondary school students in Oredo Local Government Area of Edo State? What are the steps students can take to manage their time properly? The Descriptive survey design was used for the study. A total population of 245 respondents consisting of all the students in public secondary school in Oredo Local Government Area of Edo State were used. A Likert scale questionnaire was used to elicit information from respondents, a total number of 245 (100%) questionnaires was administers and all of it (245) were properly completed and found useful for the study. Analysis and discussion of data collected for the study were descriptively done using frequency and percentage. Based on the findings of this study, the researcher reached the following conclusions: that to improve and maintain their study habits, students take notes and
concentrate during classes and do their homework regularly: understand how to manage their time properly using means such as clock alerts and reminders mostly as well as preparing a weekly study schedule and carrying out difficult academic tasks first. On that, recommendations were made as follows; School academic and extracurricular activities should be planned in a way that students will still have time to study on their own and within themselves as study groups. Government and public policy experts should make education free for all to lift the burden of financial implications from poor parents. Regular feeding of students should be practiced ensuring they are well nourished and consume foods that will improve their brain power especially. Schools through government provisions should have a standard library with enough historic and contemporary books for every subject area and an e-centre for e-reading

L’Afrique est un continent qui couvre 6% de la surface de la terre et 20%de la surface des terres émergées. L'Afrique est le deuxième continent le plus peuplé après l'Asie. Elle représente 16,4% de la population de la planète avec plus de 1,3 billion d'habitants. Le Continent est bordé par la Mer Méditerranéen au Nord, Le canal de Suez et la Mer Rouge au Nord-est, l'océan indien au Sud-est et l'océan Atlantique à l'ouest. Le partage de l'Afrique est tenu dans la conférence de Berlin de 1884 à 1885. L'Afrique est partagée ainsi: La Belgique a pris la République démocratique du Congo, l'Angola et la Mozambique sont pris par le Portugal, l'Afrique du sud, le Soudan, le Nigeria, le Kenya et l'Ouganda ont été pris par la Grand Bretagne, la France a pris le présent Sénégal, le Mali, le Niger et le Chad. L'Afrique est divisée en cinq régions principales : Afrique du Nord, Afrique de l'Ouest, Afrique Centrale, Afrique de l'Est et Afrique Australe. C'est ainsi que les pays africains étaient partagés

The primary aim of this research was to examine the effect of electronic tax payment operations in Nigeria using Edo State as a case study. The research adopted both primary and secondary data; primary data were collected through the use of questionnaire. The study adopts the survey research design. The population of the study consists of Edo State board of Internal Revenue and branches of commercial banks in Edo State. The findings revealed that there are effects of electronic tax payments system on rates collection in Edo State, findings also revealed that electronic tax payments system has prevented and curb fraud in Edo State and it was recommended that Government should support with everything in their disposal the establishment of e-tax administration so as to start reaping the benefit of high rate of compliance among taxpayers.

The soils of Owan East Local Government Area of Edo State were studied in order to update the classification, mapping and suitability evaluation done by Federal Department of Agricultural Land Resources (FDALR 1985). Soil mapping was at the reconnaissance scale; soil classification was according to the USDA and WRB systems while suitability evaluation was patterned after FAO guidelines, as modified by several scientists for rubber, oil palm, cacoa, maize and cassava. Reliability of the soil maps were
determined by the variability indices of: Coefficient of Variation (CV), Variance Ratio Test (VRT), Inter – class Correlation Coefficient (P1), Relative variance (RV) and its Complement (1 – RV). Validation of the updated work was done through a free soil survey procedure and suitability assessment for rubber on the 17.7 ha parcel of land for RRIN within the project area. The study revealed that six major mapping units were found and classified as Alfisols/Lixisols, (occupying some 66,160.26 ha), Inceptisols/Cambisols (37,803.07 ha) and Entisols/Arenosols (19,471.17 ha). The FDALR work showed two mapping units classified as Alfisol/Lixisol and without areal distribution of the units. In terms of the reliability of the soil maps for the study area, the results showed that the findings in this study is quite superior to that of the FDALR. In terms of suitability for the selected crops, for the current findngs, 70,201.5 ha (56.87%) was best suited for maize, cassava and cocoa, while 26, 624.49ha (21.57 %) was best suited for cocoa only. An area of 19,471.17 ha (15.77%) was best suited for maize, cassava and rubber while an area of 7,137ha was found not suitable for any of the 5 crops under study. The FDALR study had the same tree crops examined for their suitability, no area was
rated unsuitable and only one map was used to represent all the crops, while for arable crops, no specific crop was mentioned and it had only one map and two suitability classes. For Indices of variability: FDALR study had 46 % homogeneity within mapping units by CV while it was 87 % for the 2019 findings. For variance ratio test (VRT), no property was significantly different for the 1985 study while for the 2019, 13 properties were significantly different; Intra class correlation coefficient (pi) , in the 1985
work only CEC was accurately predicted (pi > 0.5) while in the 2019 work 7 properties were accurately predicted (pi > 0.7); for Relative variance only one property, CEC was accurately predicted compared with 9 properties (RV = 0.26 – 0.53) - 1985 and 2019 respectively. The results of the 17.71ha classification and suitability ratings agreed with that of the updated findings – being largely Inceptisol/Cambisol and only marginally suitable for rubber cultivation. Thus it can be concluded that while the FDALR study served its purpose as a pioneering attempt and hence overdue for updating. The study was highly necessary for accurate prediction of crop performance and sustainable management of the study location.

Ruderals are plants that have capacity to strive and grow in disturbed and polluted environment such as roadsides. Eleusine indica is an example of a ruderal found along the roadside. It is very widely distributed and very invasive weed. It has shown to have ability to withstand pollution created by vehicles. Automobiles usage in cities has greatly increase with development and urbanization. These pollutions include air pollutants such as NOx, SO2, O3and particulate matters like Pb, Hg and other heavy metals. The experiments were carried out to investigate the impact of these aggravated pollution as a result increase in traffic in Benin city, Edo state, Nigeria. In carrying out the experiment samples were collected along the major roads in Benin city. Ten sites were selected and these were Aduwawa market road sides, Auchi bypass roadside, Agbor road market roadside, Asaba bypass roadside, S and T Barracks market roadside, Lagos bypass roadside, Santana market roadside, Sapele bypass road, Ekenwan bypass roadside, Okhokhugbo market roadside. The comparative analysis between the sizes, numbers and structure of the stomata and epidermal cells of Eleusine indica found in polluted environment (roadsides) and less or zero polluted environment (farmland) was carried out. It was observed that an increase in the number of stomatal in the adaxial layer of the leave at sample site as against the control whereas in the abaxial layer of the cell there was a decrease in the number of stomata as compared to the control. The size of the guard cells diameter of the epidermal cells and thickness of the stomata found at both the lower and upper layers of the polluted samples decreased in relation to the samples from the less polluted environment. The anatomical modification of the epidermal cells are the potentials used by the Eleusine indica for extraction of pollution from automobile, improving the capacity for phytoremediation.

Well testing involves carrying out investigation to ascertain the condition of a well which is intended for further production. These tests are carried out at various stages of life of the well to detect well problems which affect the productivity of a well. It simply involves measuring the parameter affecting a well and how these parameters changes with time. This is then used to predict the future performance of the well and how to best enhanced such performance. It is pertinent to carry out test on well for efficient management of the well and to be able to make better decisions as regards field operations. Several well problems such as damaged permeability, skin effect, coning problem, reduction in pressure, etc. affect the productivity of a well. The research work was carried out to determine the problems associated with a well whose history was given. The given well data was used with mathematical models to detect the state or condition of the well. Several factors affecting the life of the well were computed and these were used to improve the productivity of well From analysis of the well test data, it was seen that the well had impairment which was due to reduced permeability and thus, required stimulation for improved recovery of the hydrocarbons present. Also, there was high sand and water production which also reduced the productivity of the well. Matrix acidizing and hydraulic fracturing are two suitable stimulation methods suitable for improving the well recovery
