摘要:Metro Manila air particulate samples were collected with a low volume pump and membrane filters. Pb particulate pollution levels were determined by graphite furnace AAS (GFAAS). Experimental parameters were optimized to minimize GFAAS interference effects and low volume air sampl...

摘要:Nitrate is reduced to nitrite by hydrazine sulfate and catalyzed by Cu2+ under alkaline conditions at an elevated temperature of 75°C. The intensely colored azo derivative which is formed upon reaction with a mixed reagent of 3-nitroaniline and N-(1-naphthyl)ethylenediamine ...

摘要:Metallothionein cDNA was detected in the retinas of cynomolgus monkeys (Macaca fascicularis) using RT-PCR. Sequencing of this cDNA showed almost a hundred percent sequence similarity with metallothionein cDNA from rhesus monkey kidneys. There was only a single base substitution (...

摘要:The chloroform extract of the air-dried leaves of Elephantopus scaber afforded six isolates, five of which were tested for antimutagenicity potential by the Micronucleus test. The compounds were obtained by gravity column chromatography (dry packing) and their structures were elu...

摘要:SnO2 optically transparent electrodes (OTE) were sensitized to visible light excitation through the use of copper phthalocyanine tetrasulfonate and cadmium sulfide. These dyes were blended with an ionically conducting polymer (quaternized poly-4-vinylpyridine-QPVP) and then cast ...

摘要:Methanolic extracts of six marine sponges (Spirastrella inconstans, Haliclona sp., Acanthella vulgata, Xestospongia (Petrosia) testudinaria, Clathria fasciculata, and Dysidea herbacea) collected from Matabungkay, Batangas and Guimaras, Iloilo, the Philippines, were examined for a...

摘要:The Jacobi method provides the simplest algorithm to routinely diagonalize real summetric matrices commonly encountered in chemistry courses. While more accurate and efficient procedures exist, it is particularly helpful at least for purposes of instruction. This paper intro...

摘要:A low-cost calorimeter for the determination of heat of combustion of low molecular weight compounds was assembled using easily available materials. A thermistor was employed for the measurement of the temperature change accompanying the combustion reaction. The assembled calorim...

摘要:Side-chain liquid-crystalline polymers are macromolecules consisting of! ow molecular weight mesogens covalently attached as pendant groups to the polymeric backbone through a flexible spacer. They exhibit combined thermo-electro-optical properties of the pendant liquid crystals ...

摘要:Preliminary studies done on the methanol extract of Terminalia chebula Retzius (Combretaceae), or kashi in Japanese, showed that it has a high potential for inhibiting the growth of P388/ADM leukemia cells. Further separation of the methanol extract using solvent systems of ...
