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.

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%. ...

Soybean 4-kDa peptide, a hormone-like peptide, is a ligand for the 43-kDaprotein in legumes that functions as aprotein kinase and controls cell proliferation and differentiation. As this peptide stimulates proteinkinase activity, the interaction between the 4-kDa peptide (leginsulin) and the 43-kDa protein is considered important for signal transduction. However, the mechanism of interaction between the 4-kDa peptide and the 43-kDa protein is not clearly understood.

Prothoracicotropic hormone (PTTH) plays a central role in controlling molting, metamorphosis, and diapause termination in insects by stimulating the prothoracic glands to synthesize and release the molting hormone, ecdysone. Using Autographa californicanucleopolyhedrovirus (AcNPV)-mediated transient gene transfer into the central nervous sytem (CNS) of the silkworm, Bombyx mori, we identified two cis-regulatory elements that participate in the decision and the enhancement ofPTTHgene expression in PTTH-producing neurosecretory cells (PTPCs). ...

The surface charge as well as the electrochemical properties and ligand binding abilities of the Gram-positive cell wall is controlled by the d-alanylation of the lipoteichoic acid. The incorporation of d-Ala into lipoteichoic acid requires the d-alanine:d-alanyl carrier protein ligase (DltA) and the carrier protein (DltC). We have heterologously expressed, purified, and assayed the substrate selectivity of the recombinant proteins DltA with its substrate DltC.

The budding yeastSaccharomyces cerevisiaepossesses a very flexible and complex programme of gene expression when exposed to a plethora of environmental insults. Therefore, yeast cell homeostasis control is achieved through a highly coordinated mechanism of transcription regulation invol-ving several factors, each performing specific functions. Here, we present our current knowledge of the function of the yeast activator protein family, formed by eight basic-leucine zipper trans-activators, which have been shown to play an important role in stress response....

Post-translational modifications, such as phosphorylation and acetylation of the tumour suppressor protein p53, elicit important effects on the func-tion and the stability of the resultant protein. However, as phosphorylation and acetylation are dynamic events subject to complex controls, elucidating the relationships between phosphorylation and acetylation is difficult.

The Wnt pathway controls biological processes via the regulation of target gene expression. The expression of direct Wnt target genes, e.g.cyclin D1 and MYC, is activated by the transcription factor TCF, which binds to specific sequence motifs in the promoter. Indirect target genes are regulated via transcription regulators, which are targets of the Wnt pathway.

The bacterial Lsm protein, host factor I (Hfq), is an RNA chaperone involved in many types of RNA transactions such as replication and stabil-ity, control of small RNA activity and polyadenylation. In this latter case, Hfq stimulates poly(A) synthesis and binds poly(A) tails that it protects from exonucleolytic degradation. We show here, that there is a correlation between Hfq binding to the 3¢ end of an RNA molecule and its ability to stimulate RNA elongation catalyzed by poly(A)polymerase I.

Mitochondrial biogenesis is a complex and highly regulated process that requires the controlled expression of hundreds of genes encoded in two separated genomes, namely the nuclear and mitochondrial genomes. To identify regulatory proteins involved in the transcriptional control of key nuc-lear-encoded mitochondrial genes, we have performed a detailed analysis of the promoter region of theasubunit of the Drosophila melanogasterF1F0 ATP synthase complex.
