A novel method for designing the controller of a lcl-Filter-based grid-connected inverter with considering varying system parameters - Nguyen Trung NhanTo test the dynamic response of the proposed control system, the reference current was changed from 7 ampere to 12 ampere (peak) at t = 0.1 s when the system is operating (note that the change occurs when the a-phase current arrives at the zero value). This Figure shows that the dynamic response of the proposed controller is rapid for this case....

Survey of the effects of neem leaf extract on the water quality and phytoplankton community in freshwater catfish pond in Binh Duong province - Nguyen Thanh BinhThe use of active ingredients extracted from neem is capable of affecting the quality of the pond water. At a concentration of 90 mg /L, the extracted from neem leaf have a positive impact on water quality; reduce the concentration of these parameters: COD, N-NO3-, P-PO43-, SD, and SS value. pH value was not affected by adding extract at this co...

Determination of arsenic content in wastewaterfed fish pond in Hoang mai district, Hanoi, Vietnam - Le Thai HaThe total As concentration in the water samples ranged from 23.22 to 45.86 µg/L. The highest levels were found in the inlet water and the lowest were in the outlet water. About 14% of As entered the fish pond in the SPM form. The lower As contents in the outlet sampling point may result from some natural removal processes such as sedimentation a...

The cultivation of spirulina platensis on vertical aeroponic substrates - Nguyen Thi LienAs with all plants, micro-algae photosynthesize, they assimilate inorganic carbon for conversion into organic matter. Although light is an essential substrate for photosynthesis, high light intensity causes a decrease of photosynthetic activity. The growth rate of algae is maximal at saturation intensity and decreases with both increase or decre...

Studies on distribution and fractionation of heavy metals in sediment of cau River, Vietnam - Van Dieu AnhConcentrations of metals in sampling points distributed along Cau River indicated an elevated level with a wide range of variation. At some sampling points the concentration of Cu, Pb exceeded the permitted standards of national technical regulation for water quality and sediment, leading to the risk of heavy metal pollution at local level. Resu...

Study on co-Fermentation of cow dung and giant dirt in semi-continuous anaerobic digester - Nguyen Le PhuongThis pilot scale experiment was performed to develop co-digestion process of cow dung and giant dirt in case of one-stage and two-stage processes. The reactors were fed with mixtures of CD and GD of 100 %CD, 50 %CD + 50 %GD, and 100 %GD (0.8 g VS/L*day for 17 L of substrate) and temperatures were maintained at room temperature. During operation ...
