Abstract Formaldehyde is a common emission from furniture and indoor decorations. Although the concentration of formaldehyde gas not too high in environment, it highly toxic carcinogenic. The removal potential novel type green safe nano-porous materials, Metal-Organic Frameworks (MOFs), with surface-to-volume ratio, strong adsorption capacity, low regeneration temperature was investigated. To d...

the sip gene encoding for a conserved highly immunogenic surface protein of streptococcus agalactiae was amplified using polymerase chain reaction (pcr) and subcloned into prokaryotic expression vector pet32a (+) and expressed as a recombinant protein in e. coli bl21 (de3). an indirect enzyme linked immunosorbent assay (elisa) was developed using the purified sip protein as a coating antigen, w...

Perforation of a hollow viscus is an acute abdominal drama and the accurate diagnosis highly depends on demonstration of free intra­pritoneal air. The importance of adequate examination in the demonstration of ,tiny amount ()ff air is stressed and the value of an upright chest film when the horizontal beam is tangential to the top of the diaphragm is mentioned. Before standing for chest x-ray t...

CPU performance is increasingly limited by thermal dissipation, and soon aggressive power management will be beneficial for performance. Especially, temporarily idle parts of the chip (including the caches) should be powergated in order to reduce leakage power. Current CPUs already lose their cache state whenever the CPU is idle for extended periods of time, which causes a performance loss when...

We outline a scenario of galaxy formation in which the gas in galaxy-forming regions was preheated to high entropy by vigorous energy feedback associated with the formation of stars in old ellipticals and bulges and with AGN activity. Such preheating likely occurred at redshifts z ∼ 2 – 3, and can produce the entropy excess observed today in low-mass clusters of galaxies without destroying the ...

Abstract Research on the application of liquid fuels to continuously rotating detonation was conducted. A new method mixture preparation proposed. special system fuel injection designed and tested which is based injecting into chamber a preheated partially mixed with hot air at conditions higher than rich flammability limit. The specially selected allow all evaporate in supply but prevent it fr...

This work focuses on the nonlinear control of instabilities in the combustion of a diluted dimethyl ether (DME) / air mixture under low temperature conditions. A nonlinear model predictive control (NMPC) is utilized to stabilize the combustion in simulation with the aim to specify minimum actuation dynamic requirements and develop control strategies for an existing experimental chemical reactor.

In line with the decarbonisation of power sector, carbon-free fuels are currently being investigated. particular, green ammonia or e-ammonia is a candidate fuel which will be playing key role in many energy-intensive industries. It calls for an in-depth understanding eFuels combustion characteristics flexible combustors. Therefore, present work first time numerically investigates regimes steam-...

Exposure to airborne beryllium can lead to adverse health effects in humans. Consequently, many countries have legislation in place to ensure the health and safety of workers and the wider environment. Because even very low concentrations of Be in air constitute a toxic threat to health, analytical methodology that is capable of extremely high-sensitivity measurement is required. Although trace...
