It is challenging to perform spatial geochemical modelling due to the spatial heterogeneity features of geochemical variables. Meanwhile, high quality geochemical maps are needed for better environmental management. Soil organic C (SOC) distribution maps are required for improvements in soil management and for the estimation of C stocks at regional scales. This study investigates the use of a g...
در نواحی خشک و نیمه خشک کاهش کیفیت آب آبیاری در اثر خشکسالی، پیشروی آب شور، بهره برداری بیش از حد و افت سطح آب زیرزمینی تاثیر مستقیم بر بازدهی محصولات دارد لذا از اهمیت خاصی برخوردار است. در این تحقیق پهنه بندی کیفی آب آبیاری بر اساس آنالیز پارامترهای هیدروشیمیایی وسدیم %na، ec، sar ،کلر cl و rsc و نمودار ویلکوکس در 47 چاه دشت ارسنجان انجام شده است . پهنه بندی توسط سیستم اطلاعات جغرافیایی (gis)...
In alpha-1 antitrypsin deficiency (AATD), the Z allele is present in 98% of cases with severe disease, and knowledge of the frequency of this allele is essential from a public health perspective. However, there is a remarkable lack of epidemiological data on AATD worldwide, and many of the data currently used are outdated. Therefore, the objective of this study was to update the knowledge of th...
Abstract In Wrocław over the past 20 years, recorded increase in average ambient air temperature is approx. 0.5 °C. addition, urbanisation has created a phenomenon called Urban Heat Island (UHI). The combined effect of UHI and climate change can influence groundwater by penetrating underground. elevated temperatures urban areas Subsurface (SSUHI). This study focuses on spatial distribution shal...
Air quality is one of the major issues within an urban area that affect people's living environment and health conditions. Existing observations are not adequate to provide a spatiotemporally comprehensive air information for vulnerable populations plan ahead. Launched in 2017, TROPOspheric Monitoring Instrument (TROPOMI) provides high spatial resolution (~5 km) tropospheric measurement capture...
The main reason for technological developments is to make human life more comfortable. Bioclimatic comfort areas are where people feel the most comfortable and in terms of climate. As a result global climate changes, temperature world increasing day by moreover increase living our country other countries which need spaces increases all seasons. needed summer months. However, average seasons due...
Groundwater is germane to human existence. The study assessed the physicochemical attributes of groundwater for domestic and irrigation applications. This was conducted by collecting subjecting thirty (30) samples analysis. Thirteen parameters such as pH, electrical conductivity, total dissolved solids, hardness, magnesium, calcium, sodium, iron, fluoride, chloride, sulphate, nitrate, phosphate...
Precipitation data provide a crucial input for examining hydrological issues, including watershed management and mitigation of the effects floods, drought, landslides. However, they are collected frequently from scarce often insufficient network ground-based rain-gauge stations to generate continuous precipitation maps. Recently, maps derived satellite have not been sufficiently linked rain gau...
Dust storms are a common phenomenon in arid and semi-arid areas, and their impacts on both physical and human environments are of great interest. Number of studies have associated atmospheric PM pollution in urban environments with origin in natural soil/dust, but less evaluated the dust spatial patterns over a city. We aimed to analyze the spatial-temporal behavior of PM concentrations over th...
Human immunodeficiency virus (HIV) and acquired immunodeficiency syndrome (AIDS) (HIV I AIDS) is a major public health problem in Zambia. Despite some evidence that the pandemic may have reached a plateau or perhaps has begun to decline at the national level, HIV continues to increase in different sub-populations such as adults above 19 years old. The characterization of the spatial patterns of...
