background: wearing spectacles is the most common approach in correcting the refractive errors worldwide. due to harmful effects of overexposure to solar ultraviolet radiations, the usage of multi-layer coatings in ophthalmic lenses has recently been increased. these lenses can reduce the reflections and hence increase the transmission of visible light; they can also decrease the transmission o...

Over the last deglaciation there were two transient intervals of pronounced atmospheric CO2 rise; Heinrich Stadial 1 (17.5-15 kyr) and Younger Dryas (12.9-11.5 kyr). Leading hypotheses accounting for increased accumulation in atmosphere at these times invoke deep ocean carbon being released from Southern Ocean an associated decline global efficiency biological pump. Here we present new deglacia...

We present a record of pollen and spores coprophilous fungi from sediment core Auel infilled maar, Eifel, Germany, covering the period 42,000 to 36,000 yr b2k. can show that vegetation cover was dominated by boreal forest with components steppe cold-temperate wood taxa. The proportion taxa higher during interstadials, whereas steppe-vegetation became more prominent stadials. During Heinrich sta...

The chronology of the late Pleistocene glaciation in Massif Central, France, is not well documented and there are divergent hypotheses regarding timing glacial events this area. This study aims at reconstructing fluctuations Aubrac Mountains. We present a new set Be-10 Al-26 exposure ages from twenty erratic boulders embedded six landforms. Glacial landforms were sampled to determine three stad...

A new market based approach for transmission expansion planning in deregulated environments is presented in this paper. In this approach, transmission-planning decisions are made based on the electric power market conditions. The main contribution of this research is 1) Introducing a new probabilistic tool for analyzing the electric market conditions, 2) Defining new criteria for ranking transm...

introduction and aims: until today human stomach is the only recognized habitat of h. pylori . however, recruitment of dna-based methods has made possible the detection of h. pylori in water and oral cavity, thus suggesting faecal-oral and oral-oral routes for transmission of h. pylori , respectively. in this study yeast has been proposed as a common vector for transmission of h. pylori . thus ...

introduction babesiosis is caused by apicomplexa parasites of the genus babesia. humans are commonly infected by babesia through tick bites. there is limited information available about babesia infection of humans in china. the aim of this study was to isolate the pathogen from a patient with severe parasitemia. case presentation blood samples were observed by transmission electron microscopy (...

dendrostellera lessertii (thymelaeaceae) is a toxic plant that grows in parts of iran. the anti-proliferative properties of its crude methanol extract and one of its active components, 3-hydrogenkwadaphnin (3-hk), have been established using several cancer cell lines. methods: in a further attempt to determine the mode of action, two groups of synchronously growing cells were treated with a sin...
