Solar and wind energy potential assessment for Razavi Khorasan Province in Iran

This study aims to evaluate the solar and wind energy potential across Razavi Khorasan Province,Iran,with a specific focus on the Khaf region.A preliminary assessment of mean solar radiation,mean wind speeds,and Weibull distribution parameters was conducted for different towns and zones within the province.The findings showed that Khaf has favorable characteristics for further analysis.The solar and wind energy metrics examined include global horizontal irradiance,clearness index,wind rose patterns,and turbulence intensity.At a height of 40 m,Khaf’s wind power density reached 1650 W/m^(2),indicating exceptional wind energy generation potential.Additionally,Khaf received an average annual solar radiation of 2046 kW·h/m^(2),representing significant solar energy potential.Harnessing these substantial renewable resources in Khaf could allow Razavi Khorasan Province to reduce reliance on fossil fuels,improve energy sustainability,and mitigate climate change impacts.This research contributes an in-depth assessment of Razavi Khorasan's solar and wind energy potential,particularly for the promising Khaf region.Further work may examine optimal sites for renewable energy projects and grid integration strategies to leverage these resources.

Economic Geology Study with Focus on Cu Mineralization (Fath Abad Area, Khorasan Razavi)

The study area is located in south of Khorasan-Razavi province. This region is part of central Iran, which is of high significance due to existence of metal and non-metal deposits. Considering the location of the study area, the lithology and metal-mineral indices of Dolat-Abad sheet, it can be said that their metallic deposits are economically feasible. Hence, this region is considered promising for exploration of metallic deposits. In order to achieve this goal, at first, the region’s alterations were detected by using OLI-ASTER images in ENVI software. After processing the lithogeochemical data in SPSS and GIS software, anomaly map of studied elements was obtained. Using geological map, different layers such as lithology, faults and indices were obtained. Eventually, by preparing the layers and incorporating those using the index overlay GIS modeling, promising mineralization areas in the region were identified. Results show that a significant Cu-Au mineralization has occurred in the south western region of the study area.

Seroepidemiology of bluetongue disease in small ruminants of northeast of Iran

Objective:To estimate the prevalence and distribution of bluetongue vims antibody in sheep and goats in 25 townships of Khorasan Razavi.Bluetongue is an infectious,non-contagious,arthropod born viral disease of ruminants and has been reported from most of the tropical and subtropical regions of the world.Methods:A total number of 1034 serum samples from sheep and goats were collected and transmitted to Serological Laboratory of Veterinary Council of Khorasan Razavi.Serums were screened for the presence of group-specific bluetongue virus antibody using competitive Enzyme Linked Immuno Sorbent Assay(c-ELISA).Kesults:The seropositivitv of sheep and goats for bluetongue was found to be 89.2%.The highest prevalence rate was seen in Taybad.Khalil-abad and Torbat-jam(100%)and the least prevalence rate was seen in Jovein(55%).Conclusions:The results showed that the majority of animals in the north-east of Iran are infected with bluetongue vims.High correlation between abortion history and seroposivity emphasize the economical importance of bluetongue virus in the sheep herds of the region.
