in order to investigate drought stress and plant density the yield, yield components and protein of spotted bean grain (cultivar talash), an experiment was carried out as split plots in randomized complete blocks with three replications in yasouj, in 2012. factors of the test including irrigation in three levels; without stress (control treatment), water stress in vegetative stage (interrupting...

Pool-breeding amphibian populations operate at multiple scales, from the individual pool to surrounding upland habitat to clusters of pools. When metapopulation dynamics play a role in long-term viability, conservation efforts limited to the protection of individual pools or even pools with associated upland habitat may be ineffective over the long term if connectivity among pools is not mainta...

background: due to the continuous use and also the individual’s different health conditions that use the service, swimming pools may be a suitable place to transfer different types of diseases. it has always been a serious concern from the health point of view. methods: in this descriptive study, the sampling was conducted as non- probable purposive. isfahan health center number 1 including 19 ...

High emissions from soil fumigants increase the risk of detrimental impact on workers, bystanders, and the environment, and jeopardize future availability of fumigants. Efficient and cost-effective approaches to minimize emissions are needed. This study evaluated the potential of surface water application (or water seal) to reduce 1,3-dichloropropene (1,3-D) emissions from soil (Hanford sandy l...

An investigation was carried out during April to December 2000 to study mosquito fauna and ecology in Guilan Province of northern Iran. The mosquito larvae were collected by dipping method and larval habitat characteristics recorded according to hydro-ecological features. In total, 3937 larvae of the genus Culex from 92 larval breeding sites were collected. Six species of the genus Culex; Cx. m...

A pot experiment was conducted to study the influence of various irrigation regimes on some metabolic pools of wheat and alfalfa plants. The photosynthetic pigments and soluble proteins of the tested plants significantly increased when irrigated with sewage amended with Scenedesmus quadricauda or Nostoc sp. On the other hand, soluble carbohydrates decreased in wheat shoots at different treatmen...

Inoculation of plant pathogenic bacteria in field plots has been improved by the use of organosilicone surfactants. Factors, such as cultivars, number of applications, crop stage, plant density, concentration of bacteria, and irrigation application method (overhead spray versus drop hoses), that may affect field screening of cotton cultivars for resistance to bacterial blight caused by Xanthomo...

Yield-loss models were developed for tobacco infected with Meloidogyne incognita grown in microplots under various irrigation regimes. The rate of relative yield loss per initial nematode density (Pi), where relative yield is a proportion of the value of the harvested leaves in uninfected plants with the same irrigation treatment, was greater under conditions of water stress or with high irriga...

background: infections are readily transmitted as a result of bacterial contamination of swimming pools. therefore, hygiene and preventing the contamination of swimming pools is of particular importance. the objective of this study was to determine the amount of bacterial contamination in indoor pools of yazd in 2013. methods: in this descriptive and analytical study, all indoor swimming pools ...
