Abstract The results reveal statistically significant trends with distinct slopes in quantiles for each station and season so that the changes trend of high values (quantile 0.9) evaporation were more than low 0.1). In spring, medium rates increased northern regions province (the highest slope, 0.15 mm/decade northeast), while they fell (with a slope −0.15 mm/decade) southern regions. But summe...

This study was performed to recognize the loess texture in Golestan Province, Iran using the microstructure analysis according to the electron microscopic images. Loess microstructure study allows for investigating the characteristics of particle shape, fabric, cement and porosity in microscopic images. In recent years, computer analysis has been replaced with manual calculation due to its high...

This research compared the numbers and types of different Mycobacterium species in soil samples taken from 2 areas of Golestan province, Islamic Republic of Iran, 1 with a high prevalence of tuberculosis and 1 with a low prevalence. From 220 samples, 91 grew positive cultures (41.4%) and 161 different strains were diagnosed. The most common species isolated were Mycobacterium fortuitum, M. flav...
