The storage of high level radioactive waste is still an unresolved problem of the nuclear industry, being geological disposal the most favoured option and, naturally, the one requiring the strongest geo-mechanical input. Most conceptual designs for the deep geological disposal of nuclear waste envisage placing the canisters containing the waste in horizontal drifts or vertical boreholes. The em...

Tyrosine and phenolic ring de-iodination of thyroid hormones (TH) is crucial for regulating their physiological activity. Furthermore, reactions such as de-carboxylation to thyronamines (TAM) and de-amination to thyroacetic acids (TAc) produce TH metabolites (THM) with distinct biological properties. This needs to be considered when studying effects of TH and THM. The accurate and precise quant...

By studying the problem-solving techniques that people use to design algor i thms we can learn something about bui ld ing systems that automatical ly derive algor i thms or assist human designers. In this paper we present a model of a lgor i thm design based on our analysis of the protocols of two subjects designing three convex hull algori thms. The subjects work mainly in a data-f low problem...

S[ and Sg are then said to separate (or: to screen) S± and S2. Finally, Sf is called a binary subbase if each linked system S^ (zS^ (i.e., a subcollection S^' of ^ of which any two members meet) satisfies ς\Sf'φ 0. It is well-known that a binary subbase is TΊ (cf. van Mill [9, Lemma 1]), that a space carrying a binary subbase is compact (use Alexander's lemma), and that a space is completely re...

Abstract. About fifty years ago Mahler [M] proved that if α > 1 is rational but not an integer and if 0 < l < 1, then the fractional part of α is > l apart from a finite set of integers n depending on α and l. Answering completely a question of Mahler, we show (Thm. 1) that the same conclusion holds for all algebraic numbers which are not d-th roots of Pisot numbers. By related methods we also ...

background trihalomethanes (thms) are major group of chlorinated by products, potentially hazardous and carcinogenicity of these compounds was recognized. the purpose of this study was survey on thms concentration in ahvaz drinking water. material and methods a descriptive cross-sectional study was based on 36-week sampling program during the winter, spring and summer of 2011 in water distribut...

OBJECTIVES Ideal treatment for achalasia permanently eliminates the dysfunctional lower oesophageal sphincter, relieving dysphagia and regurgitation. The aim of this study was to review the results in a series of patients undergoing video-imaged thoracoscopic Heller's myotomy (THM). METHODS Records of all patients undergoing THM by a single surgeon at one institution were analysed. Follow-up ...

For processes such as water injection in deep geothermal production, heat transfer and fluid flow are coupled affect one another, which leads to numerous challenges wellbore structure safety. Due complicated structures, consisting of casing, cement sheaths, formations under high temperature, pressure, situ stress, the effects thermo-hydro-mechanical (THM) coupling crucial for instability contro...
