This concern also applies to filter components and housings. Pall recognizes the importance of proper material selection, cleanliness standards, housing surface preparation, and specialized manufacturing processes with regard to product quality. Our knowledge allowed us to introduce practices that have become industry standards. All Pall Gaskleen filter assemblies are packaged in special double...

introduction: in this study, we evaluated the activity of garlic extract against dermatophytes which is planned to be used instead of chemical durgs. garlic has been widely used as medicine since ancient times for varieties of illnesses, including abdominal pain, parasitic infection, insect and snakebites, hemorrhoid and rheumatism. in the last decades, garlic has been reported to display antib...

introduction: the preparation of seasonal influenza virus vaccines and especially its large-scale production requirement after the emergence or reemergence of a pandemic will need an alternative host cell system due to current suboptimal methods and the insufficiency of embryonated chicken eggs needed for producing them. in response to the vital and increasing demand for alternative means for in...

In this paper, in addition to some elementary facts about the ultra-groups, which their structure based on the properties of the transversal of a subgroup of a group, we focus on the relation between a group and an ultra-group. It is verified that every group is an ultra-group, but the converse is not true generally. We present the conditions under which, for every normal subultra-group of an u...

Ultra- and nanofiltrations are utilized for the separation of polymers proteins. In this study, we have investigated application MgAl2O4 membrane produced by aerosol deposition (AD) method a polymer. A ultrafiltration on porous Al2O3 support layer was with intentionally leaving nano-sized pores instead completely dense membrane. The filtration performance removing 1 million molecular-weight pol...

Hot springs panic grass, Dichanthelium lanuginosum var sericeum (Schmoll), successfully colonizes geo-thermally heated soils that are subject to chronic temperatures ranging from 40 to 50 1C, occurs at altitudes in excess of 2500m, and tolerates low soil moisture content for extended periods of time. We utilized superoxide dismutase (SOD; EC 1.15.1.1) as an indicator of oxidative stress respons...

Exposure to expired particles and droplets carrying infectious viruses is a primary transmission pathway for respiratory diseases. Removal of via filtration from volume can drastically reduce the exposure viruses, but may remain active on surfaces as potential resuspension or fomite risks. Here, we report development macroscopic carbon nanotube air filters synthesized using ultra-thin electrica...

Three polysaccharide fractions (TPS1, TPS2 and TPS3) with different molecular weights were obtained using ultra filtration membranes from crude tea polysaccharide (CTPS) extracted from abandoned lower grade tea leaves. Each fraction contained different contents of neutral sugar, uronic acid, protein, and total polyphenols. These differences provided basis for the antioxidant and free radical sc...
