With the development of new modularization techniques, such as aspect-oriented programming and feature-oriented programming, assessing and comparing their differences in different circumstances becomes important for the user to chose, compare and synthesize these techniques. Numerous studies have been conducted to assess and compare different software modularization techniques in terms of their...

Despite surface energies dictating complete wetting, it has been classically observed that volatile alkanes do not spread completely on glass substrates, and faster evaporation rates lead to higher contact angles. Here we investigate how substrate thickness influences this behavior. For sufficiently thin find evaporate slower display apparent angles, at odds with the typical explanations involv...

High average rates of economic growth are often seen as evidence of good national leadership. This commonlyused metric substantially upward biases the growth contribution of leaders because transitory shocks also affect average growth rates. The bias is much larger in autocratic countries, because the transitory component of their growth rates tends to be much more volatile. Even identification...

The source of and timing delivery the volatile elements to Earth is a question that fundamental understanding how our planet evolved. Here, we show primitive meteorites have resolved mass-independent Zn isotope anomalies from terrestrial reservoir. Carbonaceous chondrites (CC), likely originating outer Solar System are distinct non-CC, intermediate between these two components. Modelling based ...

UNLABELLED Although widely used in air quality regulatory frameworks, the term "volatile organic compound" (VOC) is poorly defined. Numerous standardized tests are currently used in regulations to determine VOC content (and thus volatility), but in many cases the tests do not agree with each other, nor do they always accurately represent actual evaporation rates under ambient conditions. The pa...

In this work, the performance of dehydratation-desalcoholization system based on an electronic nose coupled to gas chromatography was tested. The system was used for monitoring the volatile compounds produced during a lactic fermentation with a heterofermentative bacteria (Lactobacillus fermentum Ogi E1). The monitoring was carried out with dehydratation and desalcoholization or dehydratation o...

We investigated the origin of unusual pitted terrain on asteroid Vesta, revealed in images from the Dawn spacecraft. Pitted terrain is characterized by irregular rimless depressions found in and around several impact craters, with a distinct morphology not observed on other airless bodies. Similar terrain is associated with numerous martian craters, where pits are thought to form through degass...

BACKGROUND Fungal infection of the skin is a common clinical problem, and laboratory confirmation of the diagnosis is important to ensure appropriate treatment. The identification of the species of fungus is also important, because different fungal species have different modes of transmission, and this may be of importance both in preventing re-infection and in avoidance of infection of others....

The aroma constituents of Chrysanthemum indicum L. were separated by the hydro distillation extraction method using a Clevenger-type apparatus, and were analyzed by gas chromatography-mass spectrometry (GC/MS). The yield of Chrysanthemum indicum L. flower oil was 2.0% (w/w) and the color was light golden yellow. Sixty-three volatile flavor components, which make up 89.28% of the total aroma com...
