Background: Learning Management System (LMS) is a web-based system designed to support teaching and learning at an institution. The capabilities of any LMS are required to be evaluated to detect the room for improvement. This study aimed at discovering the students’ perceptions of the functions of the LMS at Iran University of Medical Sciences (IUMS).   Methods: This qualitative s...

To improve software engineering practice it is essential to observe the socio-technical realities that surround software development within an industrial context. There is a lack of empirical knowledge of security verification and validation practice within an SME context. When coupled with the recognised importance, and inherent complexities, of such practice, it appears fundamentally sound to...

Human population pressures upon land resources have increased the need to assess impacts of land use change on soil quality. In order to assess effects of land use changes on soil quality properties in a tropical forest ecosystem of Bangladesh, soil samples were collected from adjacent well-stocked Shorea robusta natural forest, land reforested with Acacia, grassland and cultivated land. Land u...

OBJECTIVE China's food production has increased 6-fold during the past half-century, thanks to increased yields resulting from the management intensification, accomplished through greater inputs of fertilizer, water, new crop strains, and other Green Revolution's technologies. Yet, changes in underlying quality of soils and their effects on yield increase remain to be determined. Here, we provi...

Land cover maps are fundamental materials for resource management and change detection. Remote sensing technology is crucial for fast mapping with low cost. However, besides the inherent classification errors in the land cover products, numerous illogical transitions exist between the neighboring time points. In this study, we introduce a series of logical codes for all the land cover types acc...
