Seghezzo, L. (2004), Anaerobic treatment of domestic wastewater in subtropical regions, Ph.D. thesis, Wageningen University, Wageningen, the Netherlands. In this thesis, the use of upflow anaerobic sludge bed (UASB) reactors for sewage treatment was studied in the city of Salta, northwestern Argentina. The climate in this region can be defined as subtropical with a dry season. Mean ambient temp...

treatment of soils contaminated with heavy metals using plant species is a method which has been widely used in thepast. this method, which is known as phytoremediation, has been applied for pollution treatment using different plantspecies worldwide. the method has been used for remediation of various types of pollutants in laboratory, pilot andindustrial scales. the aim of this study was to co...

STOCK DEFINITION AND GEOGRAPHIC RANGE There are two species of pilot whales in the Western Atlantic — the Atlantic or long-finned pilot whale, Globicephala melas, and the short-finned pilot whale, G. macrorhynchus. These species are difficult to identify to the species level at sea; therefore, some of the descriptive material below refers to Globicephala spp., and is identified as such. The spe...

ing characteristics could be investigated. Finally the pilot plant A single tube plant Kestner evaporator'was set up at was run under 1st effect conditions in order that a comparison Illovo to investigate heat transfer characteristics when could be made with industrial 1st effect evaporators (both simulating different evaporator Tests carried out have Roberts and Kestner). This particular trial...

Teaching planning and decision making in agricultural systems at universities is often theoretically with few practical examples. Regularly there are not enough possibilities to get experience in planning a whole farm business having regard to all enterprises and all kinds of farm planning (production plan, financial plan,...). Making plans of separate parts of the farm without regarding the wh...

1. Auriculotherapy was effective in relieving the symptoms of constipation and improving quality of life for elderly people. 2. Auriculotherapy had a significant time effect in relieving symptoms of constipation, a greater reduction in scores for symptoms of constipation and quality of life, and an increased number of bowel movements per week, compared with controls. 3. The methodology of this ...

Task management (TM) is always performed on the flight deck, although not always explicitly, consistently, or rigorously. Nowhere is TM as important as it is in dealing with non-normal situations. The objective of this study was to analyze pilot TM behavior for non-normal situations. Specifically, the study observed pilots’ performance in a full workload environment in order to discern their TM...

The treatment of municipal landfill's leachate is considered as one of the most significant environmental issues. In this study a laboratory experiment was conducted through land treatment, achieving an efficient and economical method by using Vetiver plant. Moreover, the effects of land treatment of leachate of municipal landfills on the natural reduction of organic and inorganic contaminants ...

Highly toxic industrial effluents are often difficult to treat in biological wastewater treatment plants (BWWTP). Results obtained during a previous pilot-plant study allowed the identification of key parameters needed for the degradation of high concentrations of cyanides, thiocyanates and ammonium[13]. Kinetic models and parameter values were given for the pilot conditions using a synthetic e...
