The present study examined whether infants show an acceptance for extreme sour tastes and whether acceptance of sour taste is related to infants' fruit intake. Fruit intake of fifty-three infants at 6, 12 and 18 months was assessed using 3 d food records. Sour acceptance of these infants was studied at 18.1 (SD 1.5) months. Acceptance for four solutions differing in citric acid concentrations (...

We here examine the conditions of the two-phase disk model under which magnetic flares arise above the cold accretion disk due to magnetic buoyancy and produce Xrays via Comptonization of the disk’s soft radiation. We find that the disk’s ability to produce strong magnetic flares is substantially diminished in its radiation dominated regions due to the diffusion of radiation into the magnetic f...

Taste cells in taste buds of the mammalian tongue and oral cavity can detect five basic modalities: sweet, bitter, umami, salty, and sour. Each taste cell expresses distinct molecular sensors, such as G protein-coupled receptors or ion channels, which detect tastants (i.e., chemical stimuli that elicit taste sensation) and initiate an intracellular response that culminates in membrane depolariz...

A flare is a combustion device that uses air or steam to burn associated, unwanted or excess gases and liquids released during production or by pressure relief valves during unplanned over-pressuring of plant equipment in many industrial operations, such as oil-gas extraction, refineries, chemical plants, coal industry and landfills. Several environmental problems caused by gas flaring such as ...

Solar flare events of high importance were utilised to study solar latitudinal frequency distribution of the solar flares in northern and southern hemisphere for the solar cycle 22 to recent solar cycle 23. A statistical analysis was performed to obtain their relationship with sudden storm commencement (SSCs) and Forbush decrease events (Fd) of cosmic ray intensity. An 11-year cyclic variation ...

Gamma ray emission lines resulting from accelerated particle bombardment of ambient gas can serve as an important spectroscopic tool for abundance determinations. The method is illustrated by considering the gamma ray line emission observed from solar flares. The observation of similar gamma ray lines from Orion suggests the existence of large fluxes of low energy Galactic cosmic rays. The role...

Abstract. Natural gases containing impurities, namely carbon dioxide (CO2), heavy hydrocarbons, hydrogen sulfide (H2S), and water vapour, need treatment for removing acidic (CO2 H2S) to reduce corrosion enhance the heat capacity of gas. This gas is commercially known as "sour", typically, sour any that contains significant levels sulfide. The presence can affect natural quality, which also lead...

In gas and petroleum industry, the waste gas stream from the sweetening process of a sour natural gas stream is commonly referred as acid gas. Chemical Looping Combustion (CLC) technology has the potential to exploit the combustible fraction of acid gas, H2S, to produce energy obtaining a flue gas highly concentrated on CO2 and SO2, which can be cost-effectively separated for subsequent applica...

In this study, operation of compressor station has been investigated by exergy approach. Exergy analysis is a thermodynamic method which shows the irreversibility of a system quantitatively. Gas compressors are used to compensate the pressure drop along the gas pipeline significantly. The compression process causes temperature rise of gas; in this regard gas cooler is applied to reduce the temp...
