The research aimed to do the inventory and to reveal the diversity of top-soil insects related to the land utilization types in this company, i.e. conservation forest and oil-palm plantation. This study deployed survey method by collecting samples using pitfall traps. The result showed that the conservation forest and palm oil plantation were inhabited by 32 genera, 19 families, and 8 orders of top-soil insects. which mainly constituted of order Coleoptera, Hymenoptera, Collembola, Orthoptera, Diptera, Plecoptera, Hemiptera, and Dermaptera. The highest diversity (H’=3.07) was observed on nocturnal soil insects at the conservation forest, while diurnal soil insects showed the lowest diversity (H’=1.96) at the oil-palm plantation.

Numerical analysis of thermo-hydro-mechanical coupled finite element problems in fractured or porous media involves significant computational resources and parallel computing is a way to enable the use of the necessary computer power of SMP machines or clusters. An interdisciplinary collaboration is essential to port large scale and complex software applications efficiently to parallel platforms with shared or distributed memory. A comprehensive and continuously developed scientific software concept is required to treat the aspects of parallelization. We describe a resourceful and practicable software environment that enables the execution of serial or parallel applications, and which makes a transparent administration of the source code for a scientific group possible. Such software environments are difficult to design and implement, especially when solution adaptive techniques are used and three-dimensional problems on complex geometries are faced, which yield the use of unstructured meshes. In this paper, we present object-oriented software concepts and parallelization methods for serial/parallel runs and coupled/non-coupled schemes on single or multiple processes. Applications of different numerical simulations on different parallel computer platforms are described and compared to demonstrate the computational efficiency of the developed structures and procedures.

A study on the effect of ozonation and coagulation- flocculation processes on kraft pulp mill effluents has been carried out. The objectives were to determine (1)best chemical combination for coagulation-flocculation, (2)optimum pH for ozonation and to evaluate (3)suitability of ozonation as pre and post treatment of coagulation-flocculation. Removal efficiencies of color, turbidity and phenolic compounds were investigated under different conditions. Results indicated that initial acidic pH in the effluent is more favorable for ozonation at the experimented O3 flow rate. Use of 0.1g/L AlCl3.2H2O with 0.05g/L polyacrylamide gives the maximum reductions of color, turbidity and phenolic compounds in the effluent. Coagulation-flocculation followed by ozonation is a better system for the treatment of kraft pulp mill effluent. This system can reduce all the three parameters by about 90%.

This paper clarifies the role of traditional fishermen communities and related changes in natural resource management of the Tam Giang Lagoon. The results of this study show that the “Van”, a traditional community of fishermen, was organized based on geographical closeness, and kinships sharing common experiences of fishing in the Tam Giang Lagoon. The “Van” were self-adjusted, its members able to manage and exploit the fisheries resources of the lagoon. Since resource management has always been associated with the “Van” communities, the government has since come to rely on the “Van” as a nucleus with which to manage the lagoon. The “Doi Moi”, an open-door policy initiated by the Vietnamese Government in 1986 has been fueling rapid changes in the rural society of Vietnam. The most significant change in natural resource management was the establishment of Land Law 1993 which allowed the allocation of lands to households. Consequently, resources which were previously shared by the communities around the lagoon have been changing to household ownership. This increase in private ownership has reduced the common fishing ground of the Sampan people and thus narrowed their access to the natural resources on which they based their livelihood. This is one of the major reasons behind the marginalization of the Sampan people, who have sacrificed their position of being the greatest beneficiaries of the lagoon’s resources, to being the poorest.

Kitchen waste water emerging from Tirumala hills, a world famous piligrim centre was used as a source of nutrients for cultivation of Nostoc muscorum. A complete randomized design (CRD) was created for the experiment which was performed on BG-11 medium, 100% kitchen waste water (100% KW) and 75% kitchen waste water (75% KW). The physicochemical properties of kitchen waste water and the yield of biomass were determined from the cultures harvested every three days for a period of 15 days. After cultivation the kitchen waste water met the standards of safe discharge in India. The organisms could able to remove maximum of 98% of contaminants during its growth in waste water. The highest production of biomass was achieved in BG-11 medium followed by 100% KW and 75% KW.
