of priesthood, to inviolable secrecy, whatever may be the nature of the information communicated by our patients. A crime, e.g., cannot be allowed to be perpetrated, so to speak, in our presence and with our cognizance during attendance on a household, and we must not, on any account, allow ourselves to be entrapped into being made unconscious confidants of some one who is bent on mischief. It ...
A method of gas analysis is described for estimating carbon dioxide in the presence of nitrous oxide, using a modified Lloyd-Haldane apparatus. Some of the sample, after scrubbing with soda-lime, bubbles through the potash and this eliminates the solubility effect of nitrous oxide by equilibrating the standard potash solution with nitrous oxide at the tension of the sample analysed and eliminat...
three granitoid bodies, shirkuh batholith, kaffe abad and ader bolandan are exposed in nw yazd, cutting across the naiband formation (upper triassic), and overlain by cretaceous formations. shirkuh batholith is most likely of jurassic age. it seems to be the first and the most significant episode of magmatism in studied area which occurred in middle jurassic (late cimmerian) time. on the other ...
The catalytic oxidation of sulfur dioxide to sulfur trioxide over several binary (MxOy/TiO2) and ternary (V2O5/MXOY/TiO2) supported metal oxide catalysts was systematically investigated. The supported metal oxide components were essentially 100% dispersed as surface metal oxide species, as confirmed by Raman spectroscopy characterization. The sulfur dioxide oxidation turnover frequencies of the...
We present results of laboratory investigation slag-like artifacts, found on an archaeological site near Boršice, known by occurrence artifacts from the Early Neolithic (5 700–5 000 BC), Bronze and Medieval Ages. The grey-coloured foamy reach up to 5 cm in size often display original lava-like surface. These slags are formed especially strongly potassic (15–23 wt. % K2O) silicic (54–72 SiO2) gl...
A consideration of fertilizer materials furnishing the three' major plant foods reveals the fact that sources of phosphoric acid and potash have remained almost constant while the sources of nitrogen have undergone decided changes. Superphosphate has been, and probably will continue to be, our main source of phosphoric acid in most fertilizer mixtures. In the year 1900, 79.8 per cent. of the to...
Cocoa (Theobroma cacao L) is an understorey plant that highly sensitive to drought, especially at the seedling stage. In Ghana, only 20% cocoa seedlings survive dry spells within 24 months after transplanting. Potassium (K) known enhance growth of plants root increase water uptake under drought conditions. This study assessed effect different levels K fertilizer in enhancing recovery and surviv...
Effects of chemical fertilizers (urea, super phosphate and potash) on toxicities of two carbamate insecticides, carbaryl and carbofuran, individually to the N2-fixing cyanobacterium, Cylindrospermum sp. were studied in vitro at partially lethal levels (below highest permissive concentrations) of each insecticide. The average number of vegetative cells between two polar heterocysts was 16.3 in c...
Chloride is a relatively unreactive plant nutrient that has long been used as a biogeochemical tracer but also can be a pollutant causing aquatic biology impacts when concentrations are high, typically from rock salt applications used for deicing roads. Chloride inputs to watersheds are most often from atmospheric deposition, road salt, or agricultural fertilizer, although studies on agricultur...
