in order to study the effects of conventional and conservation tillage with management residue on wheat physiological properties, a field experiment was conducted in 2013-2014 at mashhad agricultural and natural resources research center of razavi khorasan province. this experiment was carried out as split plot design based on a randomized complete block design with three replications. main plo...

Anxiety undoubtedly plays an influential role in the experience of foreign language learning. This affective factor has attracted lots of researchers and has been the subject pool of scholarly research worldwide. However, research on the effect of demographic variables on foreign language anxiety (FLA) and the effect of FLA on the learners’ intention to continue their English language education...

Campylobacter jejuni 81116 and A3249 undergo a bidirectional transition between flagellated (Fla+) and aflagellated (Fla-) phenotypes. When measured in culture medium, the Fla+----Fla- transition occurred at a rate of 3.1 X 10(-3) to 5.9 X 10(-3) per cell per generation, and the Fla- to Fla+ transition occurred at a rate of 4.0 X 10(-7) to 8.0 X 10(-7) per cell per generation. However, passage ...

background: free-living amoebae (fla) are a group of ubiquitous protozoan, which are distrib­uted in the natural and artificial environment sources. the main aim of the current study was to identify the presence of fla in the recreational hot springs of sarein in ardebil province of iran. methods: seven recreational hot springs were selected in sarein city and 28 water samples (four from each h...

A photo-induced memory effect (a phenomenon similar to the persistent photoconductivity) was found in the photoinduced polycrystalline films of the In-Si-Se system. The photo-induced polycrystalline process was performed by irradiating the specimen ( the light intensity is 6 m~/cm2) at temperature 70°C. The conductivity drastically increased by irradiation of the light pulse (its intensity is 2...

The survey was carried out to investigate the presence of potentially pathogenic free-living amoebae (FLA) during flood in Chiang Mai, Thailand in 2011. From different crisis flood areas, seven water samples were collected and tested for the presence of amoebae using culture and molecular methods. By monoxenic culture, FLA were detected from all samples at 37 °C incubation. The FLA growing at 3...

This paper proposes an innovative procedure of finding efficient facility location–allocation (FLA) schemes, integrating data envelopment analysis (DEA) and a multi-objective programming (MOP) model methodology. FLA decisions provide a basic foundation for designing efficient supply chain network in many practical applications. The procedure proposed in this paper would be applied to the FLA pr...
