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 ...

Abstract Cretaceous formation in the western Tabei Uplift is significant petroleum pay zone Tarim Basin, NW China. For complex relationship between tectonic movement and depositional environment, sequence stratigraphic filling model of whole has not been established yet. Using well logs seismic data this article, evolution process are interpreted involving paleo-uplift, sedimentary water-level....

Using JERS-1 and PALSAR radar images provided by JAXA, we built regional and continental scale mosaics of Sahara that allowed to discover major geological features. The unique capability of L-band SAR to map subsurface structures in arid areas revealed several impact craters and paleo-rivers in

aptamers, or single stranded oligonucleotides, are produced by systematic evolution of ligands by exponential enrichment, abbreviated as selex. in the amplification and regeneration step of selex technique, dsdna is conversed to ssdna. asymmetric pcr is one of the methods used for the generation of ssdna. the purpose of this study was to design a random dna library for selection of aptamers wit...

deregulation policy has caused some changes in the concepts of power systems reliability assessment and enhancement. in this paper, generation reliability is considered, and a method for its assessment using intelligent systems is proposed. also, because of power market and generators’ forced outages stochastic behavior, monte carlo simulation is used for reliability evaluation. generation reli...
