In this paper, we report a geospatial assessment of the selected mine sites in the Plateau State, Nigeria. The aim of this work is to determine the impact of mining on the terrain as well as the Land Use/Land Cover (LULC) of the host communities. The Shuttle Radar Topographic Mission (SRTM) is used for the terrain mapping. The derived impact of mining on LULC between 1975 and 2014 is determined...
The mining and quarrying sector account for 10.6 per cent of the GDP 0.2 employment in 2014, according to records National Bureau Statistics. Relative gross value added sector, its contribution aggregate is small. Meanwhile, unemployment one most pressing macroeconomic problems Nigeria today. It against this background that job absorption capacity was investigated facilitate creation policies s...
Promoting Total Factor Productivity (TFP) is one of the methods to improve the competitiveness in the mining sector. Even so, it is of great importance to find a practical solution for productivity improvement. In this study, value added was measured by an innovative method based on the Divisia quantity index for seven mineral activities for the period 1994-2016. The results of calculating TFP ...
Data mining is a new and rapidly growing field. It draws ideas and resources from multiple disciplines, including machine learning, statistics, database research, high performance computing and commerce. This explains the dynamic, multifaceted and rapidly evolving nature of the data mining discipline. While there is a broad consensus that the abstract goal of data mining is to discover new and ...
BACKGROUND Higher levels of gross motor coordination are positively associated with physical activity in childhood, but little is known about how they relate to sedentary behaviour. The aim of this study was to investigate the longitudinal association between gross motor coordination at childhood and sedentary behaviour in adolescence and adulthood. METHODS Data were from the 1970 British Coh...
This study examined the relationship between motor skill competence, and physical activity in 8–9 years-old girls (N=352). Locomotor and object control skill competence was assessed, using the Test of Gross Motor Development-2, and the Physical Activity Questionnaire for Children was used to assess physical activity. Regression analysis revealed that locomotor proficiency accounted for 20% (P...
This study aims to understand leading and potential sectors in the development of archipelagic area. used time-series data obtained from Statistics Indonesia form Gross Regional Domestic Product (GRDP) East Seram Regency, Maluku Province with location quotient shift share at analysis tools. The results show that Regency has 4 basic – including agricultural, forestry fisheries; mining quarrying;...
Flooded mine workings have good potential as low-enthalpy geothermal resources, which could be used for heating and cooling purposes, thus making use of the mines long after mining activity itself ceases. It would be useful to estimate the scale of the geothermal potential represented by abandoned and flooded underground mines in Europe. From a few practical considerations, a procedure has been...
