A rapid, senstive method for NO2 analysis utilizing the chemiluminescence reaction of NO and O3 is provided by the use of the Scott Model 125 Chemiluminescense NO/NOI, Analyzer. Measurement of NO2 in the air sample by reducing it to NO by passage tgrough a converter before it enters the reaction chamber. Thermal converter will also convert, partially or completly, NH3 (and other N-componds) dep...

Policosanol is a drug substance consisting of a mixture of very long chain alcohols (C24-C34) extracted and purified from sugar cane wax. A Gas Chromatographic method using a wide-bore capillary column, and 1-eicosanol as internal standard was developed and validated for determining policosanol in 5 and 10 mg film-coated tablets. The alcohols were analyzed as trimethylsilyl derivatives. The met...

In the I = 0 sector there are more scalar mesons than can fit in one qq nonet. Consequently, many have claimed that there is in fact more than one multiplet, perhaps both qq and qqqq. Such proposals require the existence of at least two strange isodoublets (and their antiparticles). The current PDG Tables list just one state, the K∗ 0 (1430), while fits to data with Breit-Wigner forms and varia...

This paper investigates whether the family status of a company’s top officer affects managerial replacement decisions in UK firms. We report evidence that family firms are characterized by higher levels of board control and weak internal governance in the form of independent company board structures. Consistent with a managerial entrenchment hypothesis, we find evidence that family CEOs are les...

Abstract Due to the high operation temperatures, microstructural changes will occur in tungsten when used as plasma-facing material future fusion reactors. In drawn wires, potassium doping has proven prevent such undesired effectively. This strategy been adapted thin cold-rolled sheets containing 80 ppm potassium. Their texture evolution during annealing is investigated using electron backscatt...

The adrenergic blocking agent methyldopa (Aldomet) is toxic to C-1300 neuroblastoma cells in vivo. Four injections of Aldomet at a dose of 7.5 mg/injection were given over a period of 24 hr to C-1300 neuroblastoma-bearing mice. This treatment killed a significant proportion of the C-1300 neuroblastoma cells. Flow cytometric data suggest that sensitivity of tumor cells to Aldomet is not related ...

Development of solid oxide fuel cell (SOFC) anode with high resistance to coking and sulfur poisoning is highly desirable for the direct application natural gas in SOFC. Herein, a (Cu, Sm)CeO2 anchored Cu nanoparticles has been prepared. Most particle size ranges from 20 50 nm, which can increase conductivity catalytic activity anode. The Cu/CSCO10 supported exhibits maximum power density 404.6...
