Author:Lezar, S; Barros, EDate:Sep 2009Mycotoxins are fungal toxins which pose a continuous challenge to the safety and quality of food commodities in South Africa. These toxins can cause unthriftiness, loss of appetite, feed refusal, liver cirrhosis, vomiting, poor weight gain, ...Read more
Author:Kok, E; Van Dijk, J; Voorhuijzen, M; Staats, M; Lommen, A; Venema, D; Pla, M; Barros, Maria ECDate:Sep 2019The objective of this study was to quantitatively assess potato omics profiles of new varieties for meaningful differences from analogous profiles of commercial varieties through the SIMCA one-class classification model. Analytical profiles ...Read more
Author:Theron, BertusDate:Jul 2012In many scientific research environments the popular belief seems to be that scientific research cannot be subject to so-called “quality” management, at least not down to the research operational level. Examples of popular arguments behind ...Read more
Author:Beaumont, PB; Vogel, JCDate:May 2006Located between Danidiskuil and Kuruman in the Northern Cape province of South Africa is Wonderwerk Cave, where excavations from 1978 to 1996 revealed a similar to 6-m depth of deposits made up of nine Major Units (MUs), of which some have ...Read more
Author:Varzinczak, IJDate:Feb 2010As historically acknowledged in the Reasoning about Actions and Change community, intuitiveness of a logical domain description cannot be fully automated. Moreover, like any other logical theory, action theories may also evolve, and thus ...Read more
Author:Shatalov, MDate:Sep 2012The method of lines is a simple and reliable method of numerical analysis of parabolic and hyperbolic problems of mathematical physics. By means of this method mixed initial-boundary problems described by partial differential equations are ...Read more
Author:Shatalov, M; Fedotov, I; Joubert, SDate:May 2006It was shown in 1985 by Acad. V. Zhuravlev that the angular rate of a pure vibrating mode excited in a vibratory gyroscope with spherical symmetry is proportional to an inertial angular rate of the gyroscope. The effect is three dimensional ...Read more
Author:Majozi, T; Stamp, JDate:Oct 2010The use of heat integration in multipurpose batch plants to minimise energy usage has been in the literature for more than two decades. Direct heat integration may be exploited when the heat source and heat sink processes are active over a ...Read more
Author:Lysko, Albert ADate:Nov 2012A circular loop antenna is often numerically modeled using a regular polygon. This approach is simple and robust, yet it alters the circumference of the loop and may thus shift the resonance frequency in the numerical model. This letter ...Read more
Author:Candy, LP; Lasenby, JDate:Apr 2010The orientation vector differential equation was first derived by John Bortz to improve the accuracy of strapdown inertial navigation attitude algorithms. These algorithms previously relied on the direct integration of the direction cosine ...Read more
