ANALYSIS OF LAND-USE/LAND-COVER CHANGE IN ZARIA URBAN AREA: TOWARDS ATTAINING SUSTAINABLE DEVELOPMENT[]


Land-use and Land-cover change are major issues in the studies of sustainable development and integrated assessment of environmental problems. Information on the rate and kind of changes in the use of land resources is essential for proper planning, management and to regulate the use of such resources. This study assessed land-use and land-cover change in Zaria urban area. A combination of remote sensing and geographic information system (GIS) were employed for the study. The period covered is from 1986 to 2016. Four imageries (Landsat TM 1986, Landsat TM 1996, Landsat ETM+ 2006 and Landsat TM 2016) were compared to ascertain the rate and extent of change in the land-use and-land cover change of the study area. Findings from the study revealed that Zaria urban area has experienced a significant decrease in vegetation cover as a result of increase in land uses (residential, commercial, industrial institutional, etc.) as well as increase in bare land (an indication of desert encroachment) over these years. The decrease in vegetation cover poses a great threat to sustainable development within and around Zaria urban centre.


Evaluation of the Assumptions of the Linear Regression Model on the Quantile Regression Model[]


The Robustness of QRM over Linear Regression Model LRM was examined and it shows that quantile regression model contains more information than LRM. Moreover, both the LRM and QRM could not meet all the model assumptions, and this is where the robustness of QRM lies, because while LRM requires total transformation of the data or elimination of the problem variables, the QRM does not require those stringent assumptions to be met before it can be used for inference and estimation.


Is it Curse or Philosophy? A Critique[]


Frederick Nietzsche as a prominent philosopher of his time is known for his attack on Christian values and morality on the one hand and he concluded as Christianity as a source for the sickly socio-moral values as a result of the fake priests grievance during their competition with noble men. I argue that his total claim on it is a result of either misunderstanding of Christian values or a deliberate retreat of Nietzsche to cope up with the values of Christianity at least in theory. As a result, his total philosophy on Christianity and morality would even contradict or totally fail.


Application of Fourier Transform Infrared (FTIR) Spectroscopy in Study of some Irrigated edible Crops and Fish at Galena Mining Area of Nahuta, Alkaleri Local Government Area, Bauchi State, Nigeria[]


Fourier Transformation Infra-red spectroscopy analysis was used to analyze the presence of sulphur compounds in Irrigated edible crops (Beans, Maize, rice, Okro and tomatoes) and Fish. Absorption band showed C-S (800-600 cm-1); SO3 (1260-1150 cm-1);SO2 symmetric (1160-1120 cm-1); S=O (11060-1040 cm-1) stretching bonds because of absorbed dissolved sulphur ions from the soil into their shoot system.
