Different colored bell peppers (Capsicum annuum L.), green, red, and yellow were examined for their content of phenolic compounds, ascorbic acid and carotenoids as well as free radical scavenging activity using DPPH assay and antioxidant activity using ß-carotene/linoleic acid assay. Phenolic, ascorbic acid and carotenoid contents varied in different colored bell peppers. Green pepper had highe...

Abstract—Nowadays the red mud generated from Bayer alumina production process seriously threats the environment and human safety. Therefore, reduction and recycling of red mud is an urgent topic in aluminum industry. In this study, the effects of various parameters, ultrasound power, reaction temperature, leaching time, acid concentration, and solid to liquid ratio on the leaching of Fe, Al, an...

Two experiments were conducted to evaluate the effects of chemical composition of wheat shorts and red dog on energy and amino acid digestibility in growing pigs and to establish prediction models to estimate their digestible (DE) and metabolizable (ME) energy content and as well as their standardized ileal digestible (SID) amino acid content. For Exp. 1, sixteen diets were fed to thirty-two gr...

I treat three related subjects: virtual-worlds research-the construction of real-time 3-D illusions by computer graphics; some observations about interfaces to virtual worlds; and the coming application of virtual-worlds techniques to the enhancement of scientific computing. We need to design generalized interfaces for visualizing, exploring, and steering scientific computations. Our interfaces...

In this assessment we summarise advances in our knowledge of how UV-B radiation (280–315 nm), together with other climate change factors, influence terrestrial organisms and ecosystems. We identify key uncertainties and knowledge gaps that limit our ability to fully evaluate the interactive effects of ozone depletion and climate change on these systems. We also evaluate the biological consequen...

Gerade erst wurde das Urlaubsgeld gestrichen und das Weihnachtsgeld gekürzt, kurz darauf wird die Arbeitszeit verlängert – ohne Lohnausgleich. Kein Wunder, dass die Angestellten im Öffentlichen Dienst aufgebracht sind. Als spontane Reaktion auf den Beschluss der Bundesländer zur Arbeitszeitverlängerung hatte es bereits Ende März erste Proteste gegeben. Nun liegen sogar Warnstreiks in der Luft –...

Hidden blood loss typically occurs following total hip arthroplasty (THA) and total knee arthroplasty (TKA) and is thought to be related to free fatty acid (FFA). To study the effect of linoleic acid on red blood cells and to examine the pathogenesis of hidden blood loss in vivo, we generated an animal model by injecting linoleic acid into the tail veins of rats. We collected blood samples and ...

effect of different amounts of sulfur fertilizer (0, 50, 100, 150, 200, 250 kg/ha) and 200 kg/ha of thiobacillus inoculant on yield, quality and storability of two edible onion cultivars red rey and white qom were investigated. the experiments were conducted at experimental field and laboratories of the department of horticulture, seed and plant improvement institute, karaj, iran in 2007-08 cro...

Watermelon is widely propagated through grafting, after which seedlings are subjected to healing under controlled conditions including artificial lighting. Light wavelengths, such as blue, red, and far-red, impose considerable effects on seedlings, possibly carry the mature plants. The aim of present study examine whether different light wavelengths during grafted watermelon variable field cult...
