Abstract Radon and radon daughters pose significant backgrounds to rare-event searching experiments. Activated carbon, which has very strong adsorption capacity for radon, can be used removal enrichment. The internal 226 Ra concentration ultimately limits its enrichment ability. In order measure the intrinsic background study capability of Saratech activated carbon at various temperatures, a ra...

Attacks that use side channels, such as sound and electromagnetic emanation, to infer keystrokes on physical keyboards are ineffective on smartphones without physical keyboards. We describe a new side channel, motion, on touch screen smartphones with only soft keyboards. Since typing on different locations on the screen causes different vibrations, motion data can be used to infer the keys bein...

In a previous paper* Fr. Sierp and myself have dealt with some of the numerous hot springs in the Bombay Presidency. The favourable reception which that paper has received relieves me of the necessity of dwelling once more on the importance of the subject. The methods used in the present paper in measuring the radio-activity of the water and the gases are the same as in the former investigation...

The decline of pig health status is the effect of a bad air quality inside breeding facilities related to the concentration of biogases derived from the action of faecal microbial flora on urine nitrogen. Bioactivation of the environment with bacterialenzymatic mixtures is able to reduce this chemical emanation. An experimental trial has been performed to evaluate the efficacy of the bioactivat...

Using two lowland rice (Oryza sativa L.) cultivars we found that in both cases submerged-induced elongation early after germination depends on gibberellins (GAs). Submergence increases the content of the active GA 1 by enhancing the expression of GA biosynthesis genes, thus facilitating the seedlings to escape from the water and preventing asphyxiation. However, the two cultivars differ in thei...
