The design, optimization and better control of refinery processes become possible via dynamic simulation. In this article, a methanol distillation unit with three columns has been simulated to separate methanol from its impurities and water in steady and dynamic states, using commercial softwares. Moreover, it investigates, employing simulink/matlab software, the effect of variable changes on p...

Atomicity-checking is a powerful approach for finding subtle concurrency errors in shared-memory multithreaded code. The goal is to verify that certain code sections appear to execute atomically to all other threads. This paper extends Farzan and Madhusudan’s recent work on causal atomicity [1], which uses a translation to Petri nets to avoid much of the imprecision of type-system based approac...

Today it is commonplace for historical Jesus scholars to emphasize Jesus’ Jewishness. at the same time most new Testament scholars deny that he cared about the Jewish purity system, which was a central aspect of early Judaism. This article examines how such a reconstruction of the historical Jesus would influence his Jewishness, arguing that it indeed would make such a Jesus figure ‘less Jewish...

Many people judge suicide to be immoral. We have found evidence that these moral judgments are primarily predicted by people's belief that suicide taints the soul and by independent concerns about purity. This finding is inconsistent with accounts that define morality as fundamentally based upon harm considerations. In this commentary, we respond to a critique of our finding, and we provide fur...

Objective: Technetium-99m-sestamibi (-1"'Tc-MIBI) is a radiopharmaceutical imaging agent useful for assessing myocardial perfusion. We present a simple, rapid and accurate SepPak® method to confirm the radiochemical purity of "'Tc-MIBI. Methods: Technetium-99m-MIBI preparations of high (>95%), intermediate (83-90%) and low (25-43%) radiochemical purity were evaluated by the recommended thinlaye...

We explore several variations of the notion of purity for the action of Frobenius on schemes defined over finite fields. In particular, we study how these notions are preserved under certain natural operations like quotients for principal bundles and also geometric quotients for reductive group actions. We then apply these results to study the cohomology of quiver moduli. We prove that a natura...

objective(s): predegeneration is a standard technique to obtain mitotically activated and enriched cultures of schwann cells (scs). this study, for the first time, evaluated the impact of various duration of predegeneration on cell yield and enrichment of scs from dog peripheral nerve. materials and methods: dog sural nerves were subjected to 5, 10, 15 day-long in vitro predegeneration. the tot...

New Zealand Aluminium Smelters Ltd operates a smelting facility at Tiwai Point near Invercargill. The smelter produces aluminium by the electrolytic reduction of alumina in 650 cells. The cells are laid out in long lines and are grouped into tapping bays. The purity of the aluminium varies from cell to cell depending on a number of factors including the age of the cell, the purity of the alumin...

the question of the purity or impurity of non-muslims has always attracted the attention of the islamic jurists. the importance of this question has been due to the fact that the social and political interactions between muslims and non-muslims were quite inevitable. the present article is concerned first to examine the notion of purity and impurity as viewed by the sunni and shiite jurists and...
