in this study, the neutral monosaccharide composition of the extracellular polysaccharide (eps), extracted from thermal bacillus, was determined by liquid chromatography-mass spectrometry and high performance liquid chromatography. our analysis indicated that the eps consisted of rhamnose, mannose, galactose, glucose, fructose, arabinose and xylose. in addition to the neutral sugars in the eps,...

EVAL is a widely used yet frequently misunderstood SAS macro language function due to its seemingly simple form. However, when its actual argument is a complex macro expression interlaced with special characters, mixed arithmetic and logical operators, or macro quotation functions, its usage and result become elusive and problematic. In this paper, we aim to explore and demystify the intricate ...

Transforming text into executable code with a function such as JavaScript’s eval endows programmers with the ability to extend applications, at any time, and in almost any way they choose. But this expressive power comes at a price. Reasoning about the dynamic behavior of programs that use this features becomes difficult. Any ahead-of-time analysis, to remain sound, is forced to make pessimisti...

understanding the performance and role of each formation in a petroleum play is crucial for the efficient and precise exploration and exploitation of trapped hydrocarbons in a sedimentary basin. the lorestan basin is one of the most important hydrocarbon basins of iran, and it includes various oil-prone potential source rocks and reservoir rocks. previous geochemical studies of the basin were n...

ion and function application employ the notion of substitution. Recall the inference rule and its representation in LF: e1 ↪→ lam x. e1 e2 ↪→ v2 [v2/x]e1 ↪→ v ev app e1 e2 ↪→ v ev app : ΠE1:exp. ΠE2:exp. ΠE′ 1:exp→ exp. ΠV2:exp. ΠV :exp. eval E1 (lam E′ 1) → eval E2 V2 → eval (E′ 1 V2) V → eval (app E1 E2) V. As before, we transcribe this (and the trivial rule for evaluating λ-expressions) into...

The aim of the research presented in this article was to analyse processes source-rock decomposition, including kinetic parameters pyrolysis, relation type organic matter and its maturity. examined source rocks were Menilite shales from several units within Flysch Carpathians (Poland). samples analysed with use thermal methods, Rock-Eval thermogravimetry coupled an FTIR detector. Kinetic determ...

PURPOSE To determine physical characteristics of mixtures of ethylene vinyl alcohol copolymer (EVAL) and metrizamide dissolved in dimethyl sulfoxide, liquid materials developed for embolization of arteriovenous malformations. METHODS EVAL and dimethyl sulfoxide were mixed in various proportions and sterilized. The viscosity and density of each mixture was measured. Precipitation times were de...
