In the Bay of Fundy, Atlantic sturgeon from endangered and threatened populations in the USA and Canada migrate through Minas Passage to enter and leave Minas Basin. A total of 132 sub-adult and adult Atlantic sturgeon were tagged in Minas Basin during the summers of 2010-2014 using pressure measuring, uniquely coded, acoustic transmitters with a four or eight year life span. The aim of this st...
The Electric Power Research Institute conducted a study of Tidal In-Stream Power Production that is one of the best references available and has reports for download. A similar study of River Turbines describes many turbines. The U.S. Department of Energy’s Marine and Hydrokinetic Technology Database provides up-to-date information on marine and hydrokinetic renewable energy, both in the U.S. a...
conclusions in spite of what the parents believe, iron supplements not only do not cause dental carries but also they have preventive and inhibitory effects on them. furthermore, it is highly recommended that supplements containing both iron and zinc elements should be preferred over supplements containing only iron elements. materials and methods the antimicrobial effects of six different type...
teeth and t=permanent teeth) has been increasing from 1957 to 2015 years in iran. the current survey aimed to test the power of health promotion model for predicting the oral health behavior among high-school students. materials and methods: a cross-sectional study was conducted on 482 high school students in gorgan city, iran. multi-cluster sampling was used to recruit the samples. a research...
The ability to accurately evaluate hydrokinetic turbine concepts at small-scale in experimental facilities is important for the development of new devices. Problems introduced by working at lab-scale include operation in a transitional Reynolds number regime and cross-sectional blockage. These factors are shown to influence performance characteristics of a helical cross-flow turbine tested over...
In small-scale hydropower scheme, the most important component is electro-mechanical equipment. Since cost contribution of this component is high because hydrokinetic projects require negligible civil works. Turbine and alternator contribute a major fraction of the hydrokinetic projects. Thus, there is a requirement to estimates the electromechanical equipment cost for a hydrokinetic hydropower...
Numerical Simulation of a Cross Flow Marine Hydrokinetic Turbine.
primary antibody deficiencies (pad) are a group of immune system disorders, associated with decreased levels of secretory and protective immunoglobulins. because of the important role of immunoglobulins in the protection of oral cavity, patients with pads are more susceptible to dental caries or oral manifestations. this study was performed to investigate the oral and dental manifestations o...
fluoride is recognized as an effective agent for dental caries prevention. generally, the main source of fluoride intake is drinking water. in this study, fluoride content in 18 commercial brands of bottled waters was investigated. six samples from each batch of 18 iranian commercial brands of bottled waters were supplied. the fluoride content of samples was analyzed by fluoride ion selective e...
