Cohen (1948a) has reported that during the multiplication of the bacteriophages T2r+ and T4r+ in Escherichia coli, strain B, the ribonucleic acid content of the host remains constant. Similar observations were made by Kozloff et al. (1951) who investigated the origin of the nitrogen of T6r+ multiplying in the same host. Cohen (1948b) also examined the possibility that the ribonucleic acid was u...

Abstract A detailed stratigraphic investigation of the intercalation mechanism when graphite electrodes are immersed inside diluted perchloric (HClO 4 ) and sulfuric (H 2 SO electrolytes is obtained by comparing results crystals simply in same acid solutions. By combining time-of-flight secondary ion mass spectrometry (ToF-SIMS) in-situ atomic force microscopy (AFM), we provide a picture chemic...

The aims of this study was to determine the effect of organic and inorganic Zn and Cu supplements on performance, footpad dermatitis (FPD), carcass characteristics and blood profile in broiler chickens. A total of 336 one-day-old Ross 308 broiler chicks were distributed into 24 floor pen and reared for 42 days. A basal mineral premix (without Zn and Cu) was supplemented with organic or inorgani...

The pH of cheese is an important attribute that influences its quality. Substantial changes in cheese pH are often observed during ripening. A combined effect of calcium, phosphorus, residual lactose, and salt-to-moisture ratio (S/M) of the cheese on the changes in cheese pH during ripening was investigated. Eight cheeses with 2 levels of Ca and P (0.67 and 0.47% vs. 0.53 and 0.39%, respectivel...

OBJECTIVES To describe 6 h urinary lead excretion (6 h PbU) after 1 g intravenous ethylene diamine tetraacetic acid (EDTA) in organolead manufacturing workers with mixed exposure to organic and inorganic lead; to determine the predictors of lead excretion (PbU); and to determine the extent to which internal lead stores and ongoing external exposure govern blood concentrations of lead (PbB). M...

We made environmental measurements to characterize contaminants generated when basaltic lava from Hawaii's Kilauea volcano enters sea water. This interaction of lava with sea water produces large clouds of mist (LAZE). Island winds occasionally directed the LAZE toward the adjacent village of Kalapana and the Hawaii Volcanos National Park, creating health concerns. Environmental samples were ta...
