X-ray powder diffractometry/Rietveld refinement was employed to estimate the purity of several chrysotile powders for calibrating standards. α-Corundum powder was mixed into each chrysotile sample as an internal standard. X-ray diffractometry was performed on these mixtures, and the mass fractions of amorphous and impurity phase content were calculated using Rietveld refinement. The chrysotile ...

interest. The glut of milk has enabled the price to the consumer in London to be reduced to 2Jd. per pint, and this will in all probability be maintained for some time to come. It is expected that there will be a daily surplus of considerably over half a million gallons during the next three months, and one way by which the public can serve both their own interests and that of the farmers who a...

This article deals with the evaluation of the chemical purity of iodine-filled absorption cells and the optical frequency references used for the frequency locking of laser standards. We summarize the recent trends and progress in absorption cell technology and we focus on methods for iodine cell purity testing. We compare two independent experimental systems based on the laser-induced fluoresc...

Genetic therapy holds great promise for the treatment of inherited or acquired genetic diseases; however, its breakthrough is hampered by the lack of suitable gene delivery systems. Dumbbell-shaped DNA minimal vectors represent an attractive, safe alternative to the commonly used viral vectors which are fraught with risk, but dumbbell generation appears to be costly and time-consuming. We devel...

The Australian heroin “drought” was a singular event deserving of the considerable scholarly attention it has engendered. The best way to understand market disruption is to examine both supply and demand side indicators, yet data on the former have been relatively neglected. Here we explore a rich data set on heroin and methamphetamine purity from 1998-2002 in Victoria that support monthly and ...

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...

Article history: Received 30 May 2011 Received in revised form 18 October 2012 Accepted 22 October 2012 Available online xxxx Cross-pollination can be caused by birds, insects and wind. Genetically modified (GM) seeds are produced each year in a controlled environment to maintain their purity. However, pollen from the GM crop can be transferred to traditional crops. When the GM crop producers a...
