Enzymes are one of the most important biomolecules which has a wide range of applications in industrial as well as biomedical field. They are important due to their many useful properties. Their development, to a great extent, has been possible due to the availability of microbial sources. Microorganisms are of much attention because they can be produced economically and are amenable to genetic...

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...

Based on the combined use of satellite remote sensing and geographical information systems(GIS), as well as field investigation, the land-use change dynamics and the interaction between these changes are analyzed in the Zuli River Basin located in semi-arid Loess Plateau China during the period of 1987-2005, which with typical farming-pastoral region feature of northern China. The land-use chan...

The land cover classes developed under the coordination of the International Geosphere-Biosphere Programme Data and Information System (IGBP-DIS) have been analyzed for a study area that includes the Conterminous United States and portions of Mexico and Canada. The 1-km resolution data have been analyzed to produce a gridded data set that includes within each 20-km grid cell: 1) the three most ...

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...

The history and origins of proficiency testing of clinical laboratories are reviewed. Since the introduction of proficiency testing in the late 1940s, dramatic improvement in laboratory performance has been demonstrated. Nonetheless, the poor performance found two decades earlier was summoned to support the passage of the Clinical Laboratory Improvement Act of 1967 (CLIA '67).

this paper examines the effects of agricultural land productivity improvement on the economy of iran assuming that the domestic and international trade liberalizations will open up the opportunities to expand market access. a 25-sector computable general equi-librium model was developed to simulate the effects of this policy. the simulation results indicate that enhancing agricultural land prod...

This thesis examines, both theoretically and empirically, the effects of land supply restriction on housing price and housing production. The analysis is conducted in the context of a closed city, where any increase in population must be accommodated within the market. The theoretical part of the analysis extends the urban spatial theory by including natural and contrived land supply restrictio...

The Land Administration Domain Model (LADM) is one of the first ISO spatial domain standards, and has been proven one of the best candidates for unambiguously representing 3D Rights, Restrictions and Responsibilities. Consequently, multiple LADM-based country profile implementations have been developed since the approval of LADM as an ISO standard; however, there is still a gap for technical im...

An important government activity of all nation states is building and maintaining a land administration system (LAS) with the primary objective of supporting an efficient and effective land market. This includes cadastral surveys to identify and subdivide land, land registry systems to support simple land trading (buying, selling, mortgaging and leasing land) and land information systems to fac...
