The influence of sodium fumarate on rumen fermentation was investigated in vitro using batch and semi-continuous cultures of mixed rumen micro-organisms taken from three sheep receiving a basal diet of hay, barley, molasses, fish meal and a mineral-vitamin supplement (500, 299.5, 100, 91 and 9.5 g/kg DM respectively). Batch cultures consisted of 10 ml strained rumen fluid in 40 ml anaerobic buf...
New regulations by the California Air Resources Board (CARB) demand a stringent 0.02 g/hp-hr tailpipe NO x limit year 2027, requiring Selective Catalytic Reduction (SCR) catalysts to provide high conversions even at low (below 200°C) exhaust temperatures. This work describes utilizing an Electrically Heated Mixer System (EHM system) upstream of Light-Off (LO-SCR) catalyst followed conventional ...
چکیده زمینه و هدف: سوسری آلمانی (Blattella germanica, Blattodea: Blattellidae) از آفات منازل مسکونی، بیمارستانها، خوابگاهها و هتلها محسوب می شود که ناقل انواع قارچها، ویروسها، باکتریهای بیماری زا می باشد. هدف از این مطالعه، بررسی مکانیسمهای مقاومت سوسری آلمانی نسبت به سموم بندیوکارب و کارباریل به روش In vivo در شهر تهران می باشد. روش بررسی: در این مطالعه سوشهای سوسری آلمانی پس از جمع آوری ا...
This paper is concerned with the type analysis of logic programs where, by type, we mean a property closed under instantiation. We define a chain of abstractions from Herbrand constraints to logical formulas via the set of their solutions. Every step of the chain is an instance of abstract interpretation. The use of logical formulas for type analysis is a generalization of the traditional Boole...
Delayed Ettringite Formation (DEF), is one of the different Internal Sulfate Attack (ISA), a slow chemical reaction that can be responsible for degradation cementitious materials, through swelling material followed by crack diffusion in structure. The objective this study experimental characterization at local scale (10 x 10 30 mm3 samples) concrete reached DEF. composite samples, consist 15 mm...
An extension of the transferable potentials for phase equilibria united-atom (TraPPE-UA) force field to thiol, sulfide, and disulfide functionalities and thiophene is presented. In the TraPPE-UA force field, nonbonded interactions are governed by a Lennard-Jones plus fixed point charge functional form. Partial charges are determined through a CHELPG analysis of electrostatic potential energy su...
Emerging and hazardous environmental pollutants like phthalic acid esters (PAEs) are one of the recent concerns worldwide. PAEs are considered to have diverse endocrine disrupting effects on human health. Industrial wastewater has been reported as an important environment with high concentrations of PAEs. In the present study, four short-chain PAEs including diallyl phthalate (DAP), diethyl pht...
Phthalate esters (PEs), especially di-n-butyl phthalate (DBP) and di-(2-ethylhexyl) phthalate (DEHP) were detected in various water samples such as river water, well water and tap water. On degradation tests of PEs, Tempaku River water degraded almost 100% of diethyl phthalate (DEP), di-isobutyl phthalate and DBP, and approximately 70% of DEHP. All eight isolates from Tempaku River water (R1-R7...
Sponges, which constitute the phylum Porifera, are the most primitive of the multicellular animals, among all marine organisms screened. Marine sponges produce the largest number of structurally diversified natural products. In this study we investigated in vitro antimicrobial activity of Ircinia mutans collected from the Kish Island in the Persian Gulf against strains of bacteria Escherichia c...
