Researchers have done many experiments to improve their dosimetry properties by adding impurities Thermoluminescent (TL) materials. Adding the TL material requires cost, time, and equipment. The purpose of this study was construct Dosimetry (TLD) chips through different thermal processes at temperatures near melting point Lithium Fluoride powder without properties, therefore additional expense ...
Marketing campaigns of organic food emphasize utilitarian benefits and psychological as well consumer culture to enhance environmental sustainability. In order study the purchase intention food, authors developed a model using antecedents like warm glow, subjective norm, attitude perceived behavioral control. This examines for Indian USA samples thus integrated three theories: Theory Planned Be...
Values for ionized [Ca] in squid axons were obtained by measuring the light emission from a 0.1-mul drop of aequorin confined to a plastic dialysis tube of 140-mum diameter located axially. Ionized Ca had a mean value of 20 x 10(-9) M as judged by the subsequent introduction of CaEGTA/EGTA buffer (ratio ca. 0.1) into the axoplasm, and light measurement on a second aequorin drop. Ionized Ca in a...
Glow-worms are bioluminescent fly larvae (Order Diptera, genus Arachnocampa) found only in Australia and New Zealand. Their core habitat is rainforest gullies and wet caves. Eight species are present in Australia; five of them have been recently described. The geographic distribution of species in Australia encompasses the montane regions of the eastern Australian coastline from the Wet Tropics...
Wireless Sensor Networks (WSNs) consists of arbitrarily placed tiny sensors which monitor the target field. Every location of the target field is said to be with at least one sensor. The sensors must be deployed in such a way that every sensor is efficiently used to monitor the target field with less coverage loss. Glow worm Swarm Optimization (GSO) technique is swarm intelligence based techniq...
Electrolyte Cathode Discharge (ELCAD) spectrometry, a novel sensitive multielement direct analytical method for metal traces in aqueous solutions, was introduced in 1993 as a new sensing principle. Since then several works have tried to develop an operational mechanism for this exotic atmospheric glow plasma technique, however these attempts cannot be combined into a valid model description. In...
A low-pressure plasma surface treatment of polymeric powders was carried out in a circulating fluidized bed (CFB) reactor (10 mm-I.D. × 800 mm-high) with CF4 glow discharge. The effects of solid circulation rate, treatment time and radio frequency (rf) power of plasma on fluorination of high-density polyethylene (HDPE) powders have been determined. X-ray photoelectron spectroscopy (XPS) and the...
The transition from Townsend to glow discharge is investigated numerically in one space dimension in full parameter space within the classical model: with electrons and positive ions drifting in the local electric field, impact ionization by electrons (alpha process), secondary electron emission from the cathode (gamma process) and space charge effects. We also perform a systematic analytical s...
This paper provides a full equilibrium characterization of warm-glow giving à la Andreoni (1989, 1990) by extending the Andreoni-McGuire (1993) algorithm. The characterization indexes individuals according to their free-riding or “dropout” levels of the public good. The dropout level is finite for an individual whose donation is always dictated by some altruism. We show that if all individuals ...
The characteristics of post-cathode plasma maintained by a self-made DC short glow-discharge generator with grid electrodes were measured optical emission spectroscopy. discharge existed in an abnormal glow mode at voltage 250–400 V and helium pressure 3–15 Torr gap 3 mm. results indicate that the intensity distribution atom spectral lines space differs from post-anode space. temperature electr...
