Indian economy has been experiencing an average annual rate of growth of around 6 per cent since the early 1980s. Though, moderate compared to the performance of several east Asian economies during the same period, this was quite impressive compared to the performance of Indian economy during the preceding three decades when the average growth logged 3.5 per cent per annum. In terms of per capi...

Soil temperature regulates the rate of plant growth and tells us much about climatic characteristics a particular site. Climate variability extremes need to be studied there is large gap in knowledge soil during heat waves. Agricultural land highly dependent on waves, which are becoming longer, more intense frequent, it important monitor temperatures situ understand their changes Therefore, aim...

Malaria is reemerging in most endemic countries of South America. In Ecuador, malaria is endemic on the Pacific coast, in the inter-Andean valleys, and in the Amazon River basin. In the Lower-Napo region of northeastern Ecuador, malaria was considered eliminated in the 1970s, but the disease has reemerged in recent years. Three organizations are involved in malaria-related work in the area, but...

This work develops a statistical model to assess the frost risk in Rafsanjan, one of the largest pistachio production regions in the world. These models can be used to estimate the probability that a frost happens in a given time-period during the year; a frost happens after 10 warm days in the growing season. These probability estimates then can be used for: (1) assessing the agroclimate risk ...

Selecting the right model to simulate a specific watershed has always been a challenge, and field testing of watersheds could help researchers to use the proper model for their purposes. The performance of three popular Geographic Information System (GIS)-based watershed simulation models (European Hydrological System Model (MIKE SHE), Agricultural Policy/Environmental Extender (APEX) and Soil ...

This study deals with estimation of electricity demand of Iran on the basis of economic criteria using a genetic-based approach called Gene Expression Programming (GEP) as an expression-driven approach. The GEP-based mathematical model is provided based on population, gross domestic product, exports, and imports. The proposed model is derived based on available data obtained from 1992 to 2006. ...

CONTEXT The yield of in-hospital stool cultures performed more than 72 hours after admission is low, and a commonly used policy dictates that laboratories reject these cultures to save costs. However, enteropathogenic bacteria other than Clostridium difficile (EPB) may cause nosocomial illness that would be missed by use of such a "3-day rule." OBJECTIVE To develop guidelines for hospital use...

Water-yield assessment is crucial to effectively achieve water supply management at the basin scale. It affected by climate change, and Land Use/Land Cover Change (LULCC). This paper quantifies combined impact of LULCC change on yield over short long-term periods in Haraz basin, Iran. has experienced severe forest degradation, agricultural expansion, urbanization. Most lands are within plains c...
