high groundwater salinity, a high water table and secondary soil salinization are dominant conditions in eastern isfahan province, iran. this region has a low annual rainfall, high annual evaporation demand, saline soils and limited fresh water supplies. to investigate the effects of irrigation deficit and salinity on cantaloupe (cucumis melo l. var. cantalupensis) production, a field experimen...

minimum profitability of production factors is one of the most important economic features in the rural areas of iran. profitability of production factors such as land, water, capital etc. is in its lowest level in the rural areas of the country. rural economy is dependent to the agricultural economy up to a great extent. the most important factors in keeping profitability of production factors...

many organisms produce lactic acid by fermentation, but most industrially important strains are from the genus lactobacillus and rhizopus oryzae. l(+)-lactic acid is the only optical isomer for use in pharmaceutical and food industries because human body is only adapted to assimilate this form. in this research, six strains of lactobacillus and four strains of r. oryzae (known as high producer)...

Production systems with scrapped and rework items have recently become an interesting subject of research. While most attempts have been focused on finding the optimal production quantity in a simple production system, little work appears on a joint production environment. In this research, two joint production systems in a form of multiproduct singlemachine with and without rework are studied ...

The 2 1 st century challenges for genetic improvement are as they have always been and as they will always be for any century: lkeep it simple; 2harness the theory and the practice of selection into the shaping of an ideal that is economically meaningful within the context of the specific production and marketing environments; 3creatively and effectively combine the available stocks in the shap...

The overall design of an industrial crop production system should optimize the system's global parameters, such as total area required, intensity of cultivation and general production schedule. The key element is the optimal intensity of cultivation for the prevailing climatic and economic environments. A single-state-variable vegetative crop model (e.g. lettuce) was used to optimize a crop pro...

This paper introduces a novel automated camera control method for capturing desktop presentations. For this purpose, we first discuss typical features of shots and their cameraworks that frequently appear in TV programs. To realize those features in our automated video capturing system, we classify the purpose of a camerawork from two points of view: target and aspect-of-target. Then, we consid...

Studies over the last two decades have revealed profound immunomodulatory aspects of vitamin D on various aspects of the immune system. This review will provide an overview of Vitamin D metabolism, a description of dendritic cell subsets, and highlight recent advances on the effects of vitamin D on dendritic cell function, maturation, cytokine production and antigen presentation. The active for...

which dominates most of the economies in the region, relies heavily on the livestock subsector for its contribution to the gross domestic product (GDP), estimated at 32 percent in the last decades for the region as a whole (Winrock International 1992). The region's growing population relies heavily on livestock products for their daily dietary requirement. The provision of draught power and man...
