abstract geopedology is a systematic approach of geomorphic analysis for soil mapping which focuses the field operation mainly on sample area. the purpose of this study is to determine the credibility of generalization of the results of geopedological approach for similar landforms in the borujen region, using diversity and similarity indices in a soil taxonomic hierarchical structure. after a ...
The degradation rate of Mediterranean steppes, especially in North Africa is 1% per year, and this considered a high rate of degradation. This study conducted in 2014 in the south slope of the Al-Jabal Al-Akhdar, northeast Libya to quantify the vegetation recovery rate and assess selected Vegetation Indices (VIs) for mapping rangelands degradation status using remote sensing technology. Throug...
Marine protected areas are commonly seen as the most effective strategy for protecting mangroves from external human pressures but little is known about the role of public land-tenure contexts (dense settlements, agricultural or range lands and wild anthromes) on clearing rates, patch properties, and ecological condition. We addressed the following questions using a peri-urban to wild gradient ...
BACKGROUND AND AIM: We sought to carry out a systematic review and meta-analysis of the diagnostic value of epicutaneous patch testing in patients with oral lichenoid lesions (OLLs). METHODS: Bibliographic searches were conducted in electronic databases such as PubMed, the Cochrane library, EBSCO, Scopus, Web of knowledge and Google scholar from January 1990 to December 2011. Search terms re...
background: management of lymphedema is a challenging issue in surgery. a variety of operations have been used, albeit with little success. objective: to investigate the efficacy of testicular patch as a lymphatic conduit. methods: an incision was made on the inguinal area of 10 dogs and all lymph nodes of inguinal area were excised. the tunica albuginea and parenchyma near the hilum of testes...
The formation of an anisotropic landscape is influenced by natural and/or human 2 processes, which can then be inferred on the basis of geometric indices. In this 3 study, two minimal bounding rectangles in consideration of the principles of 4 mechanics (i.e. minimal width bounding (MWB) box and moment bounding 5 (MB) box) were introduced. Based on these boxes, four novel shape indices, 6 namel...
here we report a novel approach for preparation of a 6-day transdermal drug delivery system (tdds) as treatment for mild to moderate alzheimer’s disease. the spray drying method was used to prepare microparticles containing the anti-alzheimer drug. the content of the drug was determined by high performance liquid chromatography (hplc) method. the morphology and size range of the microparticles ...
In this paper, we tested the use of active and passive sensor fusion for relating forest fire history to landscape spatial patterns. Principal Components Analysis (PCA) was implemented to combine Landsat Thematic Mapper (TM) and Shuttle Imaging Radar (SIR-C) data from October 1994. Resulting PCs were converted to landscape patch maps. Plots with known fire history were delineated using a fire a...
Understanding the development of landscape patterns over broad spatial and temporal scales is a major contribution to ecological sciences and is a critical area of research for forested land management. Boreal forests represent an excellent case study for such research because these forests have undergone significant changes over recent decades. We analyzed the temporal trends of four widely-us...
Here we report a novel approach for preparation of a 6-day transdermal drug delivery system (TDDS) as treatment for mild to moderate Alzheimer’s disease. The spray drying method was used to prepare microparticles containing the anti-Alzheimer drug. The content of the drug was determined by High Performance Liquid Chromatography (HPLC) method. The morphology and size range of the microparticles ...
