Soil salinity has been recognized as the most serious problems for agriculture in arid and semi-arid areas of the world. To evaluate the changes in some ?growth parameters ?and chemical composition of two forage sorghum (Sorghum bicolor var. sudanense ?lines (KFS1, KFS2) under salinity stress [0 (control), 3, 6, 9, 12 dS/m of sodium chloride], a pot experiment was carried out at College of Agriculture, Shiraz University, Shiraz, Iran in 2012 ?. The experiment was conducted as factorial arranged in a completely randomized design with three replications. Results showed that increasing salinity levels decreased accumulation of K+, emergence percentage and other growth parameters, and increased Na+, proline and total proteins contents in shoot
Salinity is one of the problems citrus production faces around the world, and the tolerance or resistance mechanism of citrus rootstocks to salinity is not well known. This study investigates the physiological responses of four citrus rootstocks, namely Sour orange (Citrus aurantium L.), Poncirus (Poncirus trifoliate Raf.), Citromelo (Citrumelo), and Citrange (Citranges), to salinity stress in a factorial experiment, based on completely randomized design under in vitro conditions. The explants are prepared from all four rootstocks and transferred in a Murashige and Skoog (MS) solid culture medium, containing 8.9 μM BA and 0.5 μM NAA with different concentrations of sodium chloride (0, 50, 100, and 200 mM) in three replications. Based on t
Reduction in the access to health care services and spread of disease can have a negative effects on the economic growth and welfare of the community by reducing the labor force participation. Increasing government health expenditures is one of the ways to overcome these problems. However, implementing this policy, along with its positive effects, will have a negative impact on the effective labor supply of other sectors. Therefore, the purpose of this study is to investigate these effects using a computable general equilibrium model based on the 2009 social accounting matrix of Iran. The results showed that illness, reduced welfare and real GDP, but increasing government health expenditures, increased welfare in the short run and long run.
Biogenic amines (BAs) are low molecular weight organic bases formed by natural amino acids decarboxylation and trigger an array of toxicological effects in humans and animals. Bacterial amine oxidases enzymes are determined as practical tools to implement the rapid quantification of BAs in foods. Our study set out to obtain a new efficient, amine oxidase enzyme for developing new enzyme-based quantification of histamine. The soils from different sources were screened using histamine as sole carbon and nitrogen sources, and histamine oxidase producing bacteria were selected and identified using specific primers for histamine oxidase (HOD) gene. The HOD gene of six strains, out of 26 isolated histamine-utilizing bacteria, were amplified using
Extended AbstractIntroductionToday, the use of clean and renewable energy in rural areas to provide sustainable energy is a prerequisite for sustainable development. The endless of fossil fuels and their constraints in providing energy and environmental damage caused by the use of fossil fuels, necessitates the use and development of renewable energy applications, in particular solar energy utilization as a The source of sustainable energy and free of environmental pollution. The necessity of using these resources due to the depletion of conventional energy resources and the limitation of fossil resources, the negative environmental impacts of the use of hydrocarbon resources, rising prices of fossil fuels, political conflicts and its impac
In order to evaluation of value for cultivation and use of seven new spring rapeseed cultivars (Foruzan, Mahtab, Zaman, Moj, Dalgan, Z10B, SAN14) and seven commercial cultivars of Rapeseed (Sari Gol, RGS003, Hayola 420, Hayola 308, Hayola 401, Hayola 50, and Zafar) as a Reference collection were carried out in a randomized complete block design with three replications at the Seed and Plant Certification and Registration Institute-Karaj in 2015-2016. The measured agronomic traits were including, 1000-seed weight, number of silique per plant, number of seeds per silique, oil percent, Maturity date and grain yield were determined according to the UPOV instruction. The results show that, hybrid cultivars such as Hyola 50 and Hyola 401 have the
Domestic and global trends indicate that there is a need for investment in health infrastructure. Although in the recent years, large investments have been made in this area in the country, delay and cost overrun, unfinished projects and in some cases redundant facilities denote a problem. Given the experience in the world and comparative studies and case studies, public-private partnership investment models were considered. The success of these models depend on several factors, among them is a good design. With regard to the conditions and presuppositions, three different models were examined: Model type 1 for situations where it is difficult to detect and monitor the quality of health services provided; model type 2 for situations in whic
Proteases are important industrial enzymes used in different areas of industry, mainly detergent, food and leather industries. In this study, novel alkaline protease-producing bacterium was isolated from Geinarje hot spring and examined for maximum protease activity to be utilized in washing-powder. The isolated bacterium was cultured in mineral salt medium including 2% Skim Milk. Proteolytic activity of supernatant was measured by caseinolytic method. The effects of pH, temperature, SDS, Tween 80 and EDTA on protease stability and activity were investigated. The detergent compatibility of protease was assayed. On the basis of phylogenetic analysis and morphological as well as biochemical tests, the isolate was identified as a new strain of
