Sustainable development requires the decoupling of economic growth from environmental impacts and from the use of natural resources. This article gives an overview of existing approaches to using Information and Communication Technology (ICT) in the service of sustainability: Environmental Informatics, Green ICT, and Sustainable Human-Computer Interaction (HCI). These approaches are then discus...

Computer modelling has been used in the last 15 years as a powerful tool for understanding the behaviour of activated sludge wastewater treatment systems. However, computer models are mainly applied for domestic wastewater treatment plants (WWTPs). Application of these types of models to industrial wastewater treatment plants requires a different model structure and an accurate estimation of th...

If both height and weight are normally distributed, we use the Pearson’s correlation; otherwise Spearman’s correlation coefficient will be presented. Spearman’s correlation is also applicable for two categorical ordinal variables like pain intensity (no, mild, moderate, severe) with burn-surface-area (< 10%, 10% 19%, 20% 29%, ≥ 30%). Table I shows the correlation coefficient between height and ...

Ageing is accompanied by a progressive loss of skeletal muscle mass and strength, leading to the loss of functional capacity and an increased risk for developing chronic metabolic diseases such as diabetes. The age-related loss of skeletal muscle mass results from a chronic disruption in the balance between muscle protein synthesis and degradation. As basal muscle protein synthesis rates are li...

Several studies have reported that polychlorinated biphenyls (PCBs) exhibit estrogenic activity; however, it is not clear if these responses are associated with the polychlorinated hydrocarbon or its hydroxylated metabolite. In order to further test this hypothesis, a battery of in vitro and in vivo assays were used to investigate the estrogenic and antiestrogenic activities of 2,4,6,2',6'-pent...

Growth behavior of Clostridium botulinum type E beluga was studied in Acipenser persicus granular caviar treated with 5% NaCl, 5%NaCl plus 0.3% boric acid and 0.4%borax and 5%NaCl plus 0.15% methyl paraben incubated at temperatures -2, 5 and 15 °C for 224 days. The initial number of inoculated bacterial spore was 5.1×104 cfu/g caviar in each treated sample. The number of bacterial spores in sam...
