Streszczenie:

Gas-lift probe is an element of cladding failure detection system of perspective lead cooled reactor. Its function is local measurement of gaseous fission product activity in the coolant and the most defected fuel assembly localization. In the coolant leaving the defected fuel assembly the specific activity of gaseous fission products is higher than the average one in the primary circuit. In the barbotage channel of gas-lift probe gaseous fission products diffuse through the bubble interface surface into the volume of the bubbles. The bubbles deliver gaseous fission product to interface surfac

There are many gaseous substances that need to be monitored for possible damage to health or the environment. This requires many sensors. The solution to reducing the number of sensors is to use one sensor to detect several gaseous substances simultaneously. Efforts to simplify sensor systems thus lead to the use of a sensor with a suitable sensitive layer and to finding a suitable method of detecting individual gaseous substances within one sensor. The aim is to find a suitable method to detect various gaseous substances acting on the sensor. For this purpose, modified impedance spectroscopy

Sorption of pure CO2 and CH4 and CO2/CH4 binary gas mixtures in amorphous glassy Poly(2,6-dimethyl-1,4-phenylene) oxide (PPO) at 35 °C up to 1000 Torr was investigated. Sorption experiments were carried out using an approach that combines barometry with FTIR spectroscopy in the transmission mode to quantify the sorption of pure and mixed gases in polymers. The pressure range was chosen to prevent any variation of the glassy polymer density. The solubility within the polymer of the CO2 present in the gaseous binary mixtures was practically coincident with the solubility of pure gaseous CO2, up

The effect of pulsed nanosecond laser radiation (wavelength 532 nm, pulse duration 14 ns, pulse repetition frequency 6 Hz, the density of laser radiation power 0.2–0.6 J/cm2) on the tableted samples of high volatile C bituminous coal in argon medium is investigated. Among the gaseous products of pyrolysis, H2, CH4, C2H2, CO and CO2 are detected. The volume fractions of gaseous products from sample pyrolysis depending on the laser radiation power density is established. Within the laser radiation power density range 0.2–0.4 J/cm2, the volume of the formed combustible gases per unit mass of the

The behavior of the by-product produced in an exhaust tube by the semiconductor silicon carbide epitaxial growth process was evaluated. The by-product layer was a dark-colored viscous liquid; it captured precursor gases and gaseous by-products, such as hydrogen, monosilane, propane, hydrogen chloride and chlorosilanes. These captured gases were spontaneously emitted in ambient nitrogen at room temperature. By an etching process using a chlorine trifluoride gas at low concentrations in ambient nitrogen, the by-product layer could be safely decomposed to gaseous fluorides of silicon and carbon.

The separation process of atmospheric air into its components by means of cryogenic low-pressure procedure, which takes place in the Oxygen plant in the Copper Mining and Smelting Complex, yields various products of different quantities and purities. Proper assessment of the energy consumption, hence assignments production cost of individual products may present considerable problem. For that goal, the least invested technical operation was adopted as criteria, and was restrained for all costs of production and distribution of specific energy. Case study was carried out in the Oxygen factory b

Investigation of influence of gases nitric oxide and hydrogen sulfide on apoptotic cell death of Jurlat cells and mononuclear leucocytes of healthy donors was conducted. It was shown that 100 mmol sodium nitroprussidi increased the apoptosis of T lymphoblast leukemia cells after 15’ incubation. 10 and 100 mmol donor of hydrogen sulfide caused apoptotic death of Jurkat cells after 15’ incubation. 15’ exposure of nitric oxide and hydrogen sulfide donors did not lead to the changes of cell death of mononuclear leucocytes.

The use of organic waste as bio-sorbent has been carried out by many researchers in the world. Furthermore, the utilization of plants for treating wastewater is also commonly found in various environmental applications. Nevertheless, a review of the ability of banana plants (Musa spp.) as bio-sorbent to eliminate gaseous pollutants is rarely found and has not been fully understood. In this paper, lignocellulosic biomass from banana plants (bark, stem, leaves, peels, etc) was identified and reviewed. Sorption potential was discussed and taken from various literature which then evaluated to disc

Information about the limits of flame propagation within streams of homogeneous gaseous fuel-air mixtures at atmospheric pressure is presented for both low velocity streams, in the presence of pilot jet flame ignition, as well as for high velocity streams when ignited by an electric spark of adequate and constant energy. In addition to methane, representing natural gas, other gaseous fuels were considered that included hydrogen and propane. The roles of the presence of varying concentration of the diluent gases, nitrogen and carbon dioxide, with the methane and changes in the intensity of turb
