The n-butanol/n-octanol fueled reactivity-controlled compression ignition engine was numerically studied based on the KIVA-CHEMKIN code. First, knocking combustion characteristics were analyzed while functioning with a premixed n-butanol percentage of 20% (B20), since it exhibited most severe knocking. Ten local regions monitored to obtain data, such as pressure and heat release rate. oscillati...

The current exploration is conceded on VCR diesel engine. It run with cotton seed oil as alternative fuel. Initially operate the engine base fuel, later blends B10, B20, B30 at different loads. From obtained results observed higher Brake Thermal efficiency (BTE) than other of B10 and B30. pure releases high amount HC emissions all stages. fuel blend release lesser emissions. that combustion don...

The higher biodiesel content blended into diesel fuel gives the lower calorific value that may affect economy. To determine effect of using 30% mixed in (B30) compared to B20, especially on economy automotive vehicles, a road test was conducted 4 brands passenger vehicles for 50,000 km. daily route this consisted 10.6% general road, 49.9% climbing-downhill and 39.5 % highway which covers distan...

The insulin gene mutation c.137G>A (R46Q), which changes an arginine at the B22 position of the mature hormone to glutamine, causes the monogenic diabetes variant maturity-onset diabetes of the young (MODY). In MODY patients, this mutation is heterozygous, and both mutant and wild-type (WT) human insulin are produced simultaneously. However, the patients often depend on administration of exogen...

Diesel vehicles contribute substantially to emissions of NOx, an ozone precursor, and to particulate matter. Real-world in-use on-road emissions of selected diesel vehicles, fueled with B20 biodiesel and petroleum diesel, were measured during normal duty cycles using a portable emissions measurement system. Four categories of dump trucks were tested, including: (1) single rear axle with Tier 1 ...

Bacillus sp. strain UFRGS-B20 was isolated in 2012 from Brazilian land-farming soil contaminated with petrochemical oily sludge. This strain was subjected to hydrocarbon biodegradation tests, showing degradation rates of up to 60%. Here, we present the 6.82-Mb draft genome sequence of the strain, which contains 2,178 proteins with functional assignments.

PURPOSE To quantify the effectiveness of anti-VEGF antibodies (bevacizumab and B20-4.1.1) as mitigators of radiation-induced, central nervous system (brain) necrosis in a mouse model. EXPERIMENTAL DESIGN Cohorts of mice were irradiated with single-fraction 50- or 60-Gy doses of radiation targeted to the left hemisphere (brain) using the Leksell Perfexion Gamma Knife. The onset and progression...

کاهش ذخایر سوخت¬های فسیلی، افزایش قیمت نفت و آلودگی هوا استفاده از انرژی¬های تجدیدپذیر را گسترش داده است. بیودیزل سوختی جایگزین سوخت¬های فسیلی است که از روغن¬های گیاهی و حیوانی تولید می¬شود. در تحقیق حاضر اثر استفاده از سوپر شارژر بر عملکرد و آلایندگی موتور دیزل، با مخلوط¬های سوختی 0 – 20 – 35 و 50 درصد حجمی بیودیزل و سوخت دیزل، مورد بررسی قرار گرفت. برای تولید بیودیزل خالص از روغن پسماند خوراک...
