under the contemporary scenario of global climate change and increasing coastal eutrophication, baseline studies of phytoplankton diversity and distribution in relation to habitat conditions constitute the first approach to evaluate potential shifts at the base of the food webs. here we present data of phytoplankton species composition and environmental variables in winter 2006 in a temperate e...

in this study, flow field and heat transfer of al2o3-cu/water micropolar hybrid nanofluid is investigated in a permeable channel using the least square method. the channel is encountered to chemical reaction, and a constant magnetic field is also applied. the bottom wall is hot and coolant fluid is injected into the channel from the top wall. the effects of different parameters such as the reyn...

Laboratory experiments and numerical simulations were utilized in this study to assess the impact of aquifer stratification on saltwater intrusion. Three homogeneous six layered aquifers investigated. Image processing algorithms facilitated precise calculation wedge toe length, width mixing zone, angle It was concluded that length intrusion stratified is predominantly a function permeability co...

multiple sclerosis (ms) is a disease with high disabling disorders and considerable social and economic impacts. this study was conducted to analyze the spatial distribution of ms disease in tehran, iran during 2001-2012.the existing information in the ms patients' medical files who had registered in iranian ms society (imss), located in tehran office, was used for analysis. the relationship be...

Hypothalamic histaminergic tuberomammillary (TM) neurons express nicotinic acetylcholine receptors (nAChRs) with kinetic and pharmacological properties resembling those of highly Ca(2+) permeable alpha7 nAChRs. However, the Ca(2+) permeability of TM nAChR channels has not been determined. To directly evaluate the Ca(2+) permeability of TM nAChRs, patch-clamp recordings were conducted using non-...

It is well known that in the practice of the drinking water as well as of the wastewater treatment especially for the processes of pH-regulation, flocculation, precipitation or disinfection, the dosing of reagents is necessary. The costs of the automatic dosing stations are comparatively high. For the smaller water treatment plants these stations are uneconomical and charged with maintenance pr...

Glutathione is the major cellular thiol present in mammalian cells and is critical for maintenance of redox homeostasis. However, current assay systems for glutathione lack application to intact animal tissues. To map the levels of glutathione in intact brain with cellular resolution (acute tissue slices and live animals), we have used two-photon imaging of monochlorobimane fluorescence, a sele...

Thick, heterogeneous unsaturated zones away from large streams in desert areas have not previously been considered suitable for artificial recharge from ponds. To test the potential for recharge in these settings, 1.3 x 10(6) m(3) of water was infiltrated through a 0.36-ha pond along Oro Grande Wash near Victorville, California, between October 2002 and January 2006. The pond overlies a regiona...

buckle folds are common traps for hydrocarbon in several contractional provinces. buckle folds form where stratified sequences rest a top salt or some other utterly weak rock as a decollemet zone in units with high competency contrasts by a compressive stress which acted along the length of the rock layers. an important parameter affecting buckle folding of a competent zone above a mobile decol...
