Iodine is the main ingredient produced by the thyroid hormone, which playa a central role in the metabolism and the immune system. The present study aims to evaluate the effects of feeding Artemia fransiscana enriched with potassium iodide on antioxidant and immune gene expression in zebra fish (Danio rerio). Zebra larvae with an average weight of 2±0.01 mg were randomly distributed into 4 trea...
A brief overview of the concept of power laser beaming in space and its applications are presented. A direct solar-pumped iodine laser with the iodide t C & l lasant is described as an example of the power laser system.
NH(4)(C(6)H(5))(4)B represents a prototypical system for understanding aromatic H bonds. In NH(4)(C(6)H(5))(4)B an ammonium cation is trapped in an aromatic cage of four phenyl rings and each phenyl ring serves as a hydrogen bond acceptor for the ammonium ion as donor. Here the dynamical properties of the aromatic hydrogen bond in NH(4)(C(6)H(5))(4)B were studied by quasielastic incoherent neut...
The effects of different anions on the extent of electrothermal supercharging of proteins from aqueous ammonium and sodium salt solutions were investigated. Sulfate and hydrogen phosphate are the most effective anions at producing high charge state protein ions from buffered aqueous solution, whereas iodide and perchlorate are ineffective with electrothermal supercharging. The propensity for th...
Technetium-99 (Tc) and iodine-129 (I) are two long-lived fission products of high volatility, which makes their study in glass structure challenging. Both technetium and iodine have broad ranging multivalent chemistry and complex reactivity dependent on redox conditions; technetium and iodine redox may vary from Tc to Tc and from I to I. Relatively few studies have been done on their speciation...
PURPOSE To investigate the possibility that cell death in retinal detachment may occur by reactivation of apoptotic programmed cell death mechanisms. METHODS Unilateral retinal detachments were created in adult cats using 0.25% sodium hyaluronate; detached and control retinas were studied at different intervals. Internucleosomal DNA fragmentation (one of the landmarks of apoptosis) was invest...
An experiment was designed to examine a mechanism to improve embryonic survival following maternal thyroid hormone manipulation. Commercial turkey breeder hens were fed diets containing supplemental iodide to mimic changes in the maternal thyroid output during an egg production cycle (32 to 48 wk of age). Dietary iodide treatment depressed maternal blood thyroxine (T4) concentrations in a time-...
Ammonium Nitrate (AN) prilling Process is nonlinear and non stationary in nature. Due to uncertainty created by nonlinear conditions like temperature rise due to exothermic reaction in the neutraliser, level in the evaporator, velocity of the cooling air in prilling tower, temperature and moisture content of prills and size of the prills. Due to these difficulties the degree of automation is qu...
Norlin, E., 2005. Nitrogen Isotope Analysis of Ammonium and Glycine. Method Development for Aqueous Solutions and Soil Extracts. Doctor ́s dissertation. ISSN 1652-6880, ISBN 91-576-6983-X Stable isotope techniques can be used as a tool in nitrogen cycling studies of different ecosystems. The studies are based on measurement of the heavy (N)tolight (N) isotopic ratios of nitrogen in different bio...
