Different methods have been designed to calculate the air quality index in form of mathematical formula. But the formula designed by Central Pollution Control Board in 2014 is more robust to find out the air quality category. The index has been calculated based upon four parameters like particulate matters (PM10, PM2.5), sulfur oxide and nitrogen oxide. The study area has affected by different ...

Cooperative substation records of hail and thunder incidences have been used as a source of data to devclop more accurate and detailed average patterns of these phenomena. Since the accuracy and completeness of records by volunteer observers are generally considered questionable, a method of determining accurate substation records of thunder and hail was devised. The evaluation method relies st...

Water resources provided by alpine glaciers are an important pillar for people in the arid regions of west China. In this study, the Hydrologiska Byrans Vattenavdelning (HBV) light model was applied to simulate glacier mass balance (GMB) and runoff in the Koxkar River Basin (KRB) on the south slope of Mount Tumur, in the western Tianshan Mountains. Daily temperature and precipitation were calcu...

The Argentine ant is well known for its affinity for honeydew and is often associated with hemipteran outbreaks in agricultural and urban environments. It has been suggested that Argentine ants may be controlled by restricting access to honeydew, thereby forcing the ants to move or by encouraging increased liquid toxicant intake. We tested this possible control strategy by restricting Argentine...

Rapidly deployable wireless networks consist of mobile base stations and less powerful mobile hosts. The mobile base stations have to maintain wireless connectivity while on the move along pre-de ned paths. Physical obstructions and wireless range limitations may prevent a pair of mobile base stations from establishing a wireless link. We study situations of distance-constrained mobility, and f...

This paper investigates the nature of competition in the retail gasoline market using a two year panel data of weekly prices for gas stations in San Diego county. The primary dimension of product differentiation in the retail gasoline market is spatial in the sense that a gas station’s market power depends on the locations of all other gas stations. In contrast to previous empirical studies, I ...

a rain gauge network should serve general as well as specific purposes such as water supply, hydropowergeneration, flood forecasting, irrigation, and flood control. the level of accuracy a network can achieve depends onthe number and locations of gauges in the network. in this study, a rain gauge network was designed for hormozganprovince in the south of iran. monthly rainfall totals from 124 r...
