Models are used in a variety of fields, including land change science, to better understand the dynamics of systems, to develop hypotheses that can be tested empirically, and to make predictions and/or evaluate scenarios for use in assessment activities. Modeling is an important component of each of the three foci outlined in the science plan of the Land-use and -cover change (LUCC) project (Tu...

the present study aimed at estimating the amount of carbon storage and its relationship with other physical and chemical soil properties in four land-use systems including intact, protected, exploited and garden-uses areas in the northern zagros region in west azarbaijan province, iran. thirty sample plots were identified and within each plot, soil samples were taken in each land use and each s...

this research was carried out based on systematic analysis approach for evaluation of ecological resources capability of kasilian representative catchment for agricultural land use. the study area is located in southern of mazandaran province. in this study we used topography digital data, paper maps, climatology data, satellite images and gis, database and spreadsheet software. the process of ...

extended abstractintroductionin recent years, several studies around the world have shown that land use has a strong impact on water quality, and significant correlations exist between water quality parameters and land use types. generally land use types have adverse impacts on water quality, so positive relationships exist between percentages of these land use types and concentrations of water ...

Maintaining a supply–demand balance of ecosystem services (ES) is essential for enhancing the effectiveness restoration. However, inappropriate land use and reforestation practices can negatively impact this balance. In study, ES Saihanba region in China was quantified by integrating use/cover change (LUCC) data, landscape metrics, indicators. The relationship between its driving factors analyz...

Purpose. The incidence of Clostridium difficile-associated diarrhea (CDAD) has steadily increased over the past decade. A multitude of factors for this rise in incidence of CDAD have been postulated, including the increased use of gastric acid suppression therapy (GAST). Despite the presence of practice guidelines for use of GAST, studies have demonstrated widespread inappropriate use of GAST i...

 Abstract Background: Inappropriate prescription of vancomycin has been shown to be asso- ciated with induction of antibiotic resistance. The objective of this study was to deter- mine the incidence of inappropriate use of vancomycin in a tertiary care hospital in Iran. Methods: A descriptive cross-sectional investigation was performed from September 2004 to March 2005 in all units of a general...

in recent decades, as a result of population growth, industrial developments, scarcity of sources, etc. more attention has been paid to spatial planning. spatial planning needs the consideration of different goals, scenarios, criterions and constraints, which leads us to the usage of spatial multi-criteria decision analysis (mcda) methods. the mail goal of this research is to develop a novel mo...
