the activity concentrations of 226ra, 232th, 40k and 137cs in water and sediment samples from hot springs of mahallat and  soil samples from their neighboring environs  have been determined using two high resolution high purity germanium (hpge) detectors with relative efficiencies 38.5% and 55%. the activity concentrations of 226ra, 232th, 40k and 137cs in sediment samples from hot spring donbe...

IN a recent paper by Cohen & Harris [1937] it is shown that the lignin of maple wood is, to a limited extent, soluble in hot dilute sulphuric acid and also in hot water. That a fraction of lignin is soluble in water has been suspected for many years and recently it has been definitely suggested by Paloheimo [1929]. The solubility of lignin in dilute acids is discussed by Schorger [1926, p. 92] ...

Heat stress is an effective factor on immune responses, body weight, egg production and egg quality of chickens. The major effect of heat stress is due to decreased food intake and alteration in acid-base balance. During the recent years, efforts to improve laying performance at high temperatures have been relatively successful. Supplementation of the diet or drinking water with special nutrien...

The North Borneo state of Sabah is known worldwide for its beautiful islands and dive sites. Local hospitals deal with a number of marine-related injuries, including marine fauna envenomation by Scorpaenidae and Synanceiidae families of fish. We report a case of a tourist who presented with excruciating pain on her right foot after stepping on a stonefish. Despite being given parenteral analges...

Cassia tora seeds, like those of many leguminous species, have hard and impermeable coats. Germination is thought to be enhanced when seeds are scarified or soaked in concentrated sulfuric acid or hot water. This experiment shows the effect of various presown treatments on C. tora with respect to its germination behavior. Germination percentages were significantly affected by different pretreat...

background: electrocoagulation is a technique involving the electrolytic addition of coagulating metal ions directly from sacrificial electrodes. these ions coagulate with turbidity agents in the water, in a similar manner to the addition of coagulating chemicals such as alum and ferric chloride, and allow the easier removal of the pollutants. purpose of this study was to conduct experimental i...

Background: Cotton gin trash (CGT) is a lignocellulosic residue that can be used in the production of cellulosic ethanol. In a previous research, the sequential use of ultrasonication, liquid hot water, and ligninolytic enzymes was selected as pretreatment for the production of ethanol from CGT. However, an increment in the ethanol production is necessary. To accomplish that, this research eval...
