Energy flow assessment can grasp the distribution law of each energy balance term engines and optimize control parameters related structures. In this study, combustion emission performance a Euro-VI heavy-duty diesel engine were tested with different coolant temperature addition n-butanol. Research results shows that under idle high-speed conditions, position maximum in-cylinder pressure (Pmax)...

The modern day lifestyle has witnessed an exposure to different concentrations of n-Butanol in our environment. These compounds are found in different states mostly in dissolved form in aerosols, paints, dyes, medicines and cosmetics etc. However the concentration of environmental exposure in normal conditions is not lethal but it induces a reduced macrophage function in terms phagocytic activi...

Marine derived fungi provide plenty of structurally unique and biologically active secondary metabolites. In our previous study, we screened the marine sediments collected from the different coastal locations of Kanyakumari district, south India. In this study, we identified a new fungal species Aspergillus protuberus SP1 (Gen Bank Accession: HQ 386016). The n-butanol exogenous extract of A.pro...

Declining fossil fuel reserves, coupled with environmental concerns over their continued extraction and exploitation have led to strenuous efforts to identify renewable routes to energy and fuels. One attractive option is to convert glycerol, a by-product of the biodiesel industry, into n-butanol, an industrially important chemical and potential liquid transportation fuel, using Clostridium pas...

BACKGROUND Though n-butanol has been proposed as a potential transportation biofuel, its toxicity often causes oxidative stress in the host microorganism and is considered one of the bottlenecks preventing its efficient mass production. RESULTS To relieve the oxidative stress in the host cell, metallothioneins (MTs), which are known as scavengers for reactive oxygen species (ROS), were engine...

In situ measurements of Brønsted acid sites (by titration with 2,6-di-tert-butyl-pyridine) and reduced centers (by UV–vis spectroscopy) were carried out on WOx–ZrO2 with catalysts at 2.9– 32.3 W/nm2 in order to probe how these species form and act as active sites during 2-butanol dehydration. The rate of 2-butanol dehydration (per W-atom) on WOx–ZrO2 reached maximum values at intermediate WOx s...

PURPOSE To screen for substances with inhibitory effects on the proliferation of hepatocellular carcinoma (HCC) HepG2 cell line from extracts of traditional Chinese medicinal plants including Heliciopsis lobata (Merr.) Sleum, Bidens pilosa, Entada phaseoloides, Plantago major, and Smilax, and unveil their mechanism of action. METHODS 3-(4, 5-Dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium brom...

Motion sickness will not be life-threatening, but it will bring a lot of inconvenience for daily life, also reducing combat effectiveness of military troops or affecting the health and work efficiency of astronauts. In the article, a more effective mice motion sickness model which selected kaolin consumption, food intake and halo response index as evaluation indexes was firstly established. The...

Background: The aromatic plant Stachys mucronata (Lamiaceae) is endemic to the island of Crete (southern Greece), but as opposed to other native Greek members of this family, this species has never been investigated in the past with regard to its polyphenolic composition and antioxidant potency. Methods: Aerial parts of S. mucronata were exhaustively extracted and partly fractionated through pa...
