The determination of absolute purity by DSC has been an accepted technique since the mid 1960s. One source of error in the purity method, that has limited its applicability and accuracy, is uncorrected thermal lag. New DSC instrumentation incorporates these corrections directly into the heat flow signal. This superior approach leads to improved peak resolution and to more accurate purity analys...

the cytoplasmic male sterile (cms) lines that are used in production of hybrid seeds in three-line system often get contaminated with their maintainer lines. using such impure cms lines in rice hybrid seed production lead to un-uniformity and yield loss in hybrid rice. laborious and time consuming phenotypic evaluations are used for elimination of off-type plants in cms multiplication farms. th...

rna extraction is a prerequisite technique for gene expression studies, analyzing the etiology and disease progression, treatment effects, as well as designing the diagnostic methods. although many rna extraction kits have been commercialized, but these kits are expensive and are not accessible in some countries. many studies have shown that trizol is an applicable material for the rna extracti...

Practical specification languages for imperative and object-oriented programs, such as JML, Eiffel, and Spec#, allow the use of program expressions including method calls in specification formulas. For coherent semantics of specifications, and to avoid anomalies with runtime assertion checking, expressions in specifications and assertions are typically required to be weakly pure in the sense th...

We divide attempts to give the structural proof theory of modal logics into two kinds, those pure formulationswhose inference rules characterise modality completely by means of manipulations of boxes and diamonds, and those labelled formulations that leverage the use of labels in giving inference rules. The widespread adoption of labelled formulations is driven by their ability to model feature...

We give a construction that identifies the collection of pure processes (i.e. those which are deterministic, or without randomness) within a theory containing both pure and mixed processes. Working in the framework of symmetric monoidal categories, we define a pure subcategory. This definition arises elegantly from the categorical notion of a weak factorisation system. Our construction gives th...

Evolution of purity in case of factorizable interaction between an open system and an environment is investigated. We derive a simple expression for purity decrease at the first instants of evolution (when purity is close to unity). We find that purity at very small times is maximal when an initial state of an open system coincides with one of the eigenstates of the interaction operator, no mat...

years. however, the nature and initial factors associated with this serious health problem have not been studied yet. methods: to understand this issue, a cross-sectional study was conducted and sixty treatment and nontreatment seekers who met the diagnostic and statistical manual of mental disorders, 4th ed., text revision (dsm.iv-tr) criteria for drug dependence with mean age of 28.7 (± 8.3) ...

In this paper, we discuss on the existence of filtrations of modules having good properties. In particular, we focus on filtered homomorphisms called strict, and show that there exists a filtration which makes a filtered homomorphism a strict filtered homomorphism. Moreover, by using this result, we study purity for filtered modules over a Gorenstein filtered ring.

Guided by appraisal-based models of the influence of emotion upon judgment, we propose that disgust moralizes--that is, amplifies the moral significance of--protecting the purity of the body and soul. Three studies documented that state and trait disgust, but not other negative emotions, moralize the purity moral domain but not the moral domains of justice or harm/care. In Study 1, integral fee...
