Efficient delineation of conservation areas is a great challenge in maintaining biodiversity. Kernel density estimators (KDEs) are a powerful tool in this perspective, but they have not been applied at the population level on patch-distributed organisms. This would be particularly worthy for species that need broad habitats beyond those where they can be sampled; such as terrestrial lands for p...

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 ...

  Urbanization is one of the most significant global changes. The rapid growth in urban area isimposing high pressure to land and their resources. With regard to various ecological services of the Hyrcanian ecosystems and the necessity to conserve them, this research aimed to investigate the growth trend of urban areas and their impacts on land suitability of the conservational patches in Korga...

Paying attention to the spatial placement of the elements (man-made or natural) based on the landscape pattern and ecological processes in urban design would have a considerable impact on both human and the nature. In a way that the discords in the placement of patchs in respect to each other, or in respect to visual corridors and urban matrixes lead to the unwanted results in the cities. The e...

the support vector machine (svm) is a relatively new machine learning method which is increasingly being applied to engineering problems and have yielded encouraging results. because of complex behavior of elastoplastic of web panels of plate girders under patch loading, almost none of the proposed methods provides consistent and accurate predictions of patch load capacity. consequently, altern...

the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...

background: cutaneous manifestations are commonly observed in the neonatal period. it is important to differentiate physiologic skin lesions from pathologic ones to avoid parents’ concerns. regarding this, the current study aimed to investigate the frequency and localization of salmon patch (sp) and mongolian spot (ms) in iranian newborns to assess the potential relationship between the neonata...

Changes in wetland ecosystems have a critical impact on the local ecology and species diversity. Different development scenarios policies are key factors influencing their changes. Therefore, we studied changes of wetlands middle Yangtze River basin (MYRB) 2001–2020, patch-generated land use simulation (PLUS) model random forest (RF) method were applied to predict analyze under different MYRB f...
