The geological and hydrogeophysical assessment of the groundwater prospect/potential in Angwan Zakara and its environs, Karu Local Government, Nasarawa State, North-Central, Nigeria has been carried out in this study. The study area covers 25km2.The area is underlain by the Basement Complex of the North-Central Nigeria consisting of Medium grained biotite granite, biotite gneiss, phyllite and un-mappable muscovite schist with structural features such as joints, veins, foliation, faults, and xenoliths trending NW-SE direction. Forty Nine (49) Vertical Electrical Sounding were carried out in the study area using Omega Resistivity Terrameter, GPS12 Garmix with a maximum cable spread of AB/2=100m and MN/2=5m. The results obtained from the field data were interpreted using IXID Software for quantitative analysis. True resistivity map, piezometric map, basement resistivity map and depth to basement map were prepared and interpreted using computer software for qualitative analysis (SURFER 8). From the IXID interpreted results, five (5) curve types were obtained from the acquired data namely A, H, KH, AH, and HK curve types are the dominant. The study area showed depth to basement ranges from 20-90m. That revealed good groundwater potential. The study area revealed 4-7 lithologic sequences consisting of top soil, laterite, clay, weathered/ fractured basement however the host rocks in the study area are biotite granite, quartzite and schistose-gneiss. The results obtained shows that the direction of water flows revealed five ridges R1-R5 and four depressions D1-D4 with receptacles trends of the ridges are R1 and R2:NW-SE; R3 N-S, R4 : NE-SW and R5; E-W. The geoelectric sections were produced and correlated with the geology of the study area and it was found to be in conformity with the each other. Based on this, the study area is zoned into three namely good, moderate and poor groundwater potential zones.

The purpose of this article is to identify characteristics of the work situation that could encourage or increase the commitment of teachers and curriculum is defined according to two modalities characterizing the organization of teaching work in the school facility: cellular versus integrated. A process for evaluating teachers’ and school administrations’ conceptions is then developed with reference to this organization of school career paths. The empirical study focuses on 5 primary school teams trained for three years in the development and evaluation of their collective arrangements. An analysis of the responses (N == 64) to a questionnaire enabled us to compare the trainees’ conceptions with those of other teachers. The results show that the tested system modifies the perceptions of the practitioners in order to better take into account the inputs of the two professional groups (teachers and principals) involved in the curriculum, the diversity of the learners and the inclusion of a personal practice improvement dynamic.

The Place and Pedagogical Function of the Scientific Image in Morocca Life and Earth Sciences Textbooks (Published)

The discovery of details, knowledge of the structures and composition of biological and geological elements is a very important step in the understanding of the scientific phenomena programmed in the SVTs lessons. Thus, scientific evolution has made it possible to explore different levels of organisation at ever deeper levels, whether in biology or geology, through the innovation of instruments and tools for exploration and observation, ranging from a simple magnifying glass to sophisticated techniques such as tomography or medical imaging. Textbooks transpose the results of these observations into scientific images that help learners to understand the phenomena under study as well as to develop a critical mind towards the proposed contents and to problematize their own knowledge within the framework of a competency-based approach that is adopted by the Moroccan education system. With the aim of evaluating the place and functions of scientific images of order: microscopic, magnifying observations and medical imaging, we analysed a corpus of 12 textbooks from the Moroccan educational system. We selected one copy of different accredited textbooks from each level of education. These are the textbooks for scientific awakening for the six years of primary education, three textbooks for middle school and three for high school. The analysis is carried out with the help of a self-developed grid which takes into account the percentages of each type of scientific images studied and their functions. The results showed that there is an evolution in the appearance of the scientific images studied as one progresses towards the second year of the baccalaureate: almost the majority of primary school textbooks do not include microscopic or magnifying observations or medical images, but they appear in the other levels with percentages that differ from one textbook to another. Microscopic observations are the most abundant among the other types of scientific images studied. Thus, scientific images with an illustrative function predominate, while those with a heuristic function and recommended in the competency-based approach are present in only a small percentage.

Air Quality Index Assessment in Some Parts of Porthacourt Metropolis, Nigeria (Published)

The assessment determines the air quality status in some parts of Port Harcourt city and environs. The amount of air pollutants emitted into the environment are measured and described in relation to seasonal variations in the concentration levels of gases in the air sample with a view to assess the air quality status in Port Harcourt. Some industries within the study area include Pabod Breweries, plastcom in Transamadi axis, Fibow, dulfil in Choba axis, eleme Petrochemical in the oilmil/eliozu axis just mention but a few. Pollutants such as TSPM, SOx, CO and Pb in wet and dry seasons were measured in association with meteorological parameters.  Air monitoring gadgets such as Kestrel 4500 Compound weather Tracker (for measurement of metrological parameters and Digit 970 hand- held gas analyser for measuring the gasses) were employed in the monitoring.  The average wind speed within the dry season was 0.78m/s, while the average wind speed at wet season is 1.53m/s.  Average temperature observed within the study area is 26.350C in wet season and 33.20C in dry season. From the analysis of the result gotten from data collation in this work, the measured concentration of TSPM was high at 95.83ug/m3 in the wet season while it1661 ug/m3 was in the dry season. For CO, Rumuomasi was the location with a high value of 4.57 ppm in the wet season while Oil mill with a value of 32.37 ppm was highest in dry season. Similarly, SO2 had a high value of 0.74 ppm in the wet season and 1.26 ppm in the dry season. Finally, Lead (Pb), had Oil mill as its hotspot with a value of 0.77 ppm in wet season and high around Trans Amadi area with a value of 0.91 ppm in the dry season. A detailed analysis of the result observed that a mean concentration of the gaseous pollutants was higher in the dry season than the wet season. They were found to have exceeded the permissible limits as given by the FMEnv, NAAQS and FEPA with dominant pollutants like Pb, and CO having hotspots in Trans-Amadi, Choba and Oil mil  areas. The only area that had limited air pollutant exposures was at Air Port Juction, OMAGWA mapped as a control area for this assessment

Assessment of Anthropogenic Activities and Their Impact on Ngong Hills Forest in Kajiado County, Kenya: A Remote Sensing Approach (Published)

Human beings are dependent on forests for various livelihood needs. Forests offer a variety of benefits, including ecological, social as well as economic benefits. As such, the development and conservation of forests around the world is vital. Monitoring of the forest ecosystem is mandatory in order to detect any changes in the ecosystem. Forest cover change detection gives an opportunity to track the productivity, health and the forest cover as well over the years so as to enable proper management, promote conservation and enhance functionality. Optical and radar remote sensors make it possible to monitor changes by use of various analytical techniques that include visual interpretations. The study investigated how remote sensing can be applied to detect change in forest ecosystem and to assess the rate of change of Ngong Hills Forest in Kenya. The project sought to determine whether anthropogenic activities are the major cause of the change in Ngong Hills Forest. Data from satellite images was analysed from 1984 to 2019 to identify the changes that have occurred on the ecosystem. Landsat and Rapid-Eye images were used to inform on change detection. In this case, rapid eye data was found to be better than Landsat data in informing on change detection because of its high resolution thus high precision and better results. The changes depicted by the remotely sensed data were mapped for ease of analysis and visualization. The research depicted a massive decrease in the forest cover despite the afforestation efforts by the Kenya Forest Service (KFS) in the 1990s. The forest has been depreciating massively from 1995 depicting greater deforestation rates between the years 2010 and 2019. This depreciation has been acknowledged by the KFS as it is said to be occurring due to the anthropogenic activities mainly settlement and logging. The means of detecting change by use of remote sensing is thus able to identify the exact areas that change has occurred and thus provide insight for the Kenya Forest Service and other ecosystem protection bodies on the most affected areas and the extent of change. Once the study area is mapped, it is possible to calculate the areas that have decreased in vegetation quantity, areas where increase has occurred as well as the areas that have remained unchanged. The findings of the study make it possible for management agencies to enforce conservation because of the presence of reliable data.
