Composting is a useful waste treatment for environmental problem, but composting experiment is challenging due to large-scale requirement. Thus, laboratory-scale reactor is of interest for composting experiment. The capability of laboratory-scale reactor to simulate large-scale composting was determined by assessing the quality of produced compost via germination index.

The study determines the predominant hydrogeological controls on salinity distribution and salinization/freshening, proposing conceptual models to explain the different vertical distributions of groundwater salinity at the coastline. An improved understanding of the sources of salinity and the hydrogeological controls will subsequently provide support for the future management of groundwater in the Western Port Basin, and serve as a template for how to unravel complex salinity distributions in coastal aquifers, and their relationships to palaeo- and recent geomorphological histories.

In this thesis, focus on the wireless links between devices equipped by deployed operating personnel and intermediary access point infrastructure. We use multi-radio (MR) platforms, wireless devices with multiple and diverse transceiver technologies, to produce robust and reliable links through adaptive control of available transceivers. Primarily, we study the application of intelligent control techniques, namely reinforcement learning (RL), for adaptive control over diverse transceivers to achieve the desired robustness and reliability under dynamic environmental conditions.

In this study, we aimed to use ferrate as an all-in-one alternative for the removal of chlorine-consumed compositions such as organic, color, turbidity, iron, and manganese in river water for water supply purposes. Ferrate (FeO42-) was simultaneously employed as coagulant and oxidant for purification of Saigon River water in order to reduce the formation of disinfection byproducts in the produced tap water.

An understanding of soil microorganisms as part of soil system and interactions between the diversity of producers and of decomposers, have major consequences on the functioning of agricultural ecosystems. Soil microorganisms control the transformation and mineralization of natural compounds and xenobiotics. The soil micro biota, existing in high density and diversity, rapidly modify the energetic performance and activity rates to changing environmental conditions.

Pest control practices in the vegetable crops have been heavily dominated by the routine use of broad-spectrum insecticides to control pests. Concerns have emerged about the adverse consequences of over use of pesticide. These consequences include short and longterm health hazards, contamination and environmental degradation. To minimize the pest losses farmers heavily depend on the chemical pesticides and accessing pest management information from the pesticide dealers due to weak state extension support system.

Wastewater Management is one of the most concerns in any urban area. An efficient management contributes to the wealth of a community, never the less a poor management leads to unpredictable hazards related to health, environmental pollution, etc. In developed countries, the issues of water and sanitation are solved, floodings are well controlled.

The p25rum1 is an inhibitor of Cdc2 kinase expressed in fission yeast and plays an important role in cell-cycle control. As its amino-acid sequence suggests that p25rum1 has putative phosphorylation sites for mitogen-activated protein kinase (MAPK), we investigated the ability of MAPK to phosphorylate p25rum1. Direct in vitro kinase assay using GST-fusion proteins of wild-type as well as various mutants of p25rum1 demonstrated that MAPK phosphorylates the N-terminal portion of p25rum1 and residues Thr13 and Ser19 are major phosphorylation sites for MAPK....

The activity of outer membrane phospholipase A (OMPLA) is regulated by reversible dimerization. However, native OMPLA reconstituted in phospholipid vesicles was found to be present as a dimer but nevertheless inactive. To investigate the importance of dimerization for control of OMPLA activity, a covalent OMPLA dimer was constructed and its properties were compared to native OMPLA both in a micellar detergent and after reconstitution in a phospholipid bilayer.

Fructose 2,6-bisphosphate (Fru-2,6-P2 ) plays an important role in the regulation of major carbohydrate fluxes as both allosteric activator and inhibitor of target enzymes. To examine the role of Fru-2,6-P2in the regulation of hepatic carbohydrate metabolism in vivo,Fru-2,6-P2 levels were elevated in ADM mice with adenovirus-mediated overex-pression of a double mutant bifunctional enzyme, 6-phos-phofructo-2-kinase/fructose-2,6-bisphosphatase (n¼6), in comparison to normal control mice (control,n¼6). ...

Humanb2 -glycoprotein I (b2 GPI), also known as apolipo-protein H, has been implicated in haemostasis and the pro-duction ofanti-phospholipid antibodies. There is a wide range ofinterindividual variation in b2GPI plasma levels that is thought to be under genetic control, but itsmolecular basis remains unknown. To understand the genetic basis of b2GPI variation, we analyzed the 5¢ flanking region ofthe b2GPIgene for mutation detection by DHPLC and identi-fied a point mutation at the transcriptional initiation site ()1CfiA) with a carrier frequency of 12.1%. ...
