The investigation of elemental sulfur solubility plays critical roles on sour gas reservoir development. In this paper, the was directly measured by static method with samples from well M1 a in Sichuan Basin. results show that ranges 0.001 g/cm 3 to 0.968 at 40–98.9 MPa and 15–49.8 MPa. increases increasing temperature pressure, especially when pressure is greater than 30 Moreover, H 2 S conten...

compressibility factor and viscosity of natural gasses are of great importance in petroleum and chemical engineering. to calculate the natural gas properties in the pipelines, storage systems and reservoirs, the exact values of gas compressibility factor and viscosity are required. a new method that allows accurate determination of compressibility factor and gas viscosity for all types of: swee...

BACKGROUND The polycystic kidney disease-like ion channel PKD2L1 and its associated partner PKD1L3 are potential candidates for sour taste receptors. PKD2L1 is expressed in type III taste cells that respond to sour stimuli and genetic elimination of cells expressing PKD2L1 substantially reduces chorda tympani nerve responses to sour taste stimuli. However, the contribution of PKD2L1 and PKD1L3 ...

Sour taste is detected by taste receptor cells that respond to acids through yet poorly understood mechanisms. The cells that detect sour express the protein PKD2L1, which is not the sour receptor but nonetheless serves as a useful marker for sour cells. By use of mice in which the PKD2L1 promoter drives expression of yellow fluorescent protein, we previously reported that sour taste cells from...

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 (...

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...

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...
