ABSTRACT Interstellar complex organic molecules (iCOMs) have been identified in different interstellar environments including star forming regions as well cold dense molecular clouds. Laboratory studies show that iCOMs can be formed either gas phase or the solid state, on icy grains, from ‘non-energetic’ (atom-addition/abstraction) energetic (UV-photon, particle bombardments) processes. In this...

Communication signals may be energetically expensive or inexpensive to produce, depending on the function of the signal and the competitive nature of the communication system. Males of sexually selected species may produce high-energy advertisement signals, both to enhance detectability and to signal their size and body condition. Accordingly, the proportion of the energy budget allocated to si...

We present experimentally measured adsorption isotherms of CO2, H2, and N2 on a phenol-formaldehyde resin-based activated carbon, which had been previously synthesized for the separation of CO2 in a precombustion capture process. The single component adsorption isotherms were measured in a magnetic suspension balance at three different temperatures (298, 318, and 338 K) and over a large range o...

Measuring of heat flow curves at temperatures near the in-service range have become a standard for stability and compatibility assessments nitrocellulose (NC)-based energetic materials. The typical technique to realise this demand is microcalorimetry. are summarized effect rates all reaction heats in mixture. propellant composition has significant influence on shapes curves. To assess firmer ba...

The main objective of this study was assessment the performance, emissions and combustion characteristics a diesel engine using RME–1-butanol blends. In assessing process, great importance placed on evaluating stability process. Not only were typical COVIMEP indicators assessed, but also non-burnability characteristic stages: ignition delay, time 50% heat release end combustion. evaluation proc...

Young radio pulsars shed vast amounts of rotational energy, sometimes as high as 100,000 times the total energy loss rate from the sun. The wide range of phenomena resulting from this energy loss include: glitches, timing noise, jets, bow shocks, bullets and plerions and are be reviewed from an observational perspective. Past and proposed surveys for young radio pulsars are summarised along wit...

The AMPAC-GaTech Partnership fosters research aimed at opening and developing new avenues and compounds that fit the American Pacific Corporation (AMPAC)’s potential market. Under this umbrella, we are exploring advanced propellants technologies (ionic liquids, energetic polymers), azide chemistry, and applied polymers (agriculture, biomedical). The energetic ionic liquids is one example to ill...

This paper reports a plenary thermodynamic model of a novel solar system for water heating in buildings. Energy and exergy analyses are used to characterize the exergy destruction rate in any component and calculate system overall efficiency. The system consists of a solar evaporator, a heat exchanger to produce hot water, and an auxiliary pump. A computer simulation program using EES software ...

The purpose of this work is to develop two types dietary supplements for celiac (energy-rich and fiber-rich bars) as well optimize the formulations bars made from puffed non-puffed cereals. To combination components, a mixture design was created. Based on sensory evaluation, optimal were selected, which then evaluated in terms biochemical properties, color antioxidant properties. main results i...
