With the advent of global energy crisis, use sustainable green has become more and widespread utilization rate photovoltaic industry in high-altitude desert areas is getting higher higher. This article mainly studies intelligent control system area based on microgrid power supply. The uses shielded twisted pair to transmit signals, electrostatic interference electromagnetic induction are effect...

Land use and land cover change have been of great concern in global change research in recent years. Base on comparison with the remote sensing data in1982 and 2000 and field investigation, the results of land cover and land use change were obtained by the method of landscape analysis. Ten types of land use were identified: riparian woods, riparian shrubbery, desert shrubbery, desert grassland,...

The previous researches focused on the influence of anthropogenic greenhouse gases exerting global warming, but not consider whether desert sand may warm the planet, this could be improved by accounting for sand's physical and geometric properties. Here we show, sand particles (because of their geometry) at the desert surface form an extended surface of up to 1 + π/4 times the planar area of th...

The Meteosat Second Generation (MSG) geostationary platform equipped with the Spinning Enhanced Visible and Infrared Imager (SEVIRI) instrument provides observations of the Earth every 15 min since 2004. Based on those measurements, we present a new method called North African Sandstorm Survey (NASCube) to: (i) generate day/night remote sensing images in order to detect sandstorms over the Saha...

in february and march 2005, the archaeological survey of righ saray desert in the northern part of varzaneh was conducted. ancient rigsray is an area which has been buried by the sandy dunes at the western margin of the marsh gavkhoni. during this project nearly 100 archaeological sites were identified and recorded. one of the most important sites identified by the survey is saba 9 which is the...

Desert locust swarms intermittently damage crops and pastures in sixty countries from Africa to western Asia, threatening the food security of 10% of the world’s population. During the 20th century, desert locust control operations began organizing, and nowadays, they are coordinated by the Food and Agriculture Organization (FAO), which promotes a preventative strategy based on early warning an...
