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.
裂缝或多孔介质中热-水-机械耦合有限元问题的数值分析涉及大量的计算资源,并行计算是一种使SMP机器或集群能够使用必要的计算机能力的方法。跨学科协作对于将大规模和复杂的软件应用程序有效地移植到具有共享或分布式内存的并行平台是必不可少的。需要一个全面的、持续发展的科学软件概念来处理并行化的各个方面。我们描述了一个资源丰富和实用的软件环境,它使串行或并行应用程序的执行成为可能,并且使科学小组的源代码的透明管理成为可能。这样的软件环境很难设计和实现,特别是当使用解决方案自适应技术和面对复杂几何形状的三维问题时,这会产生非结构化网格的使用。在本文中,我们提出了面向对象的软件概念和并行化方法,用于单进程或多进程的串行/并行运行和耦合/非耦合方案。描述并比较了不同数值模拟在不同并行计算机平台上的应用,以证明所开发的结构和程序的计算效率。

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.

OPTIMIZATION OF COAGULATION-FLOCCULATION AND OZONATION PROCESSES FOR THE TREATMENT OF KRAFT PULP MILL EFFLUENT 混凝-絮凝-臭氧氧化工艺处理硫酸盐纸浆厂废水的优化

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%.
研究了臭氧氧化和混凝-絮凝工艺对硫酸盐纸浆厂废水的处理效果。目的是确定(1)混凝-絮凝的最佳化学组合,(2)臭氧化的最佳pH值,以及评估(3)臭氧化作为混凝-絮凝前处理和后处理的适用性。考察了不同条件下对色度、浊度和酚类化合物的去除率。结果表明,在实验O3流量下,出水初始酸性pH值更有利于臭氧化。使用0.1g/L AlCl3.2H2O和0.05g/L聚丙烯酰胺可最大限度地降低出水中的颜色、浊度和酚类化合物。混凝-絮凝+臭氧氧化是一种较好的处理硫酸盐纸浆厂废水的系统。该系统可将这三个参数降低约90%。

Wastewater-contaminated soil is noticed in many residential and industrial districts in various countries in the world. Domestic and industrial wastewater contains many injurious chemical compositions. Many underground septic tanks have been used to collect domestic wastewater from dwelling buildings in Tahta city, Egypt. Soil samples were taken at the depth of foundation level of the buildings and a series of mineralogical and chemical analysis was carried out for contaminated soil samples. Also, physical engineering properties of soil were identified and analyzed at different periods of wastewater exposure time and at variant distances from the contamination source (septic tank). Results showed significant adverse effects of the contaminated soil on mineralogical, chemical and physical properties.

Malaria is still a serious cases all over the world especially in tropical country with a predict number 300-500 millions people infected per year. The resistence cases of these anti-malaria substance make a new effort to find the new strategy against malaria. This study aim to summarize the potential Piper genus as the source of potential antimalarial compound and recent research of callus induction in piper plant to obtain metabolites.The study of Piper genus represent the 11 Piper species were chemically studied and assayed against the plasmodium. The potential antimalarial compound isolates from several Piper genus were 20,60-Dihydroxy-40-methoxydihydro-chalcone,3-Farnesyl-p-hydroxybenzoic acid, Piperine, Chabamide, Benzoic acid derivatives, Guineensine, pellitorine, brachystamide B, sarmentine, and sermentosine, 5,8-Hydroxy-7-methoxyflavone, Prenylated hydroxybenzoic acid, 4-Nerolidylcatechol, Piperitone, Champor, and Viridiflorol (EO). An effort to propagate necessary antiplasmodial resources especially by callus induction has been conducted for 7 Piper species such as Piper betle, P. colubrinumm, P. crocatum, P. longum, P. nigrum, P. permucronatum and P. solmsianum to obtain higher content of secondary metabolites with a different plant growth hormone (PGR) supplementation while there are most of Piper genus have not been well studied. It conclude that callus culture could be the promising method to obtain antimalarial secondary metabolites as antimalarial.
疟疾仍然是全世界特别是热带国家的一个严重病例,预计每年有3 -5亿人感染。这些抗疟药物的耐药病例为寻找抗疟新策略做出了新的努力。本文旨在综述胡椒属潜在的抗疟化合物来源以及胡椒植物愈伤组织诱导获得代谢产物的最新研究进展。对11种胡椒属进行了化学研究,并测定了其对疟原虫的抗性。从胡椒属中分离到的潜在抗疟化合物有:20,60-二羟基-40-甲氧基二氢查尔酮、3-法尼基对羟基苯甲酸、胡椒碱、Chabamide、苯甲酸衍生物、几内亚碱、pelitorine、短叶胺B、沙门汀和血清托辛、5,8-羟基-7-甲氧基黄酮、戊酰化羟基苯甲酸、4-Nerolidylcatechol、胡椒酮、Champor和Viridiflorol (EO)。为了获得较高的次生代谢物含量,我们对7种辣椒(Piper betle, P. colubrinum, P. crocatum, P. longum, P. nigrum, P. permucronatum和P. solmsium)进行了愈伤组织诱导繁殖,特别是通过添加不同的植物生长激素(plant growth hormone, PGR)来获得必要的抗疟原虫资源,而大部分辣椒属植物的次生代谢物含量还没有得到很好的研究。结果表明,愈伤组织培养可能是获得抗疟次级代谢物的有效方法。

The resistence cases of these anti-malaria substance make a new effort to find the new strategy against malaria. This study aim to summarize the potential Piper genus as the source of potential antimalarial compound and recent research of callus induction in piper plant to obtain metabolites.The study of Piper genus represent the 11 Piper species were chemically studied and assayed against the plasmodium. The potential antimalarial compound isolates from several Piper genus were 20,60-Dihydroxy-40-methoxydihydro-chalcone,3-Farnesyl-p-hydroxybenzoic acid, Piperine, Chabamide, Benzoic acid derivatives, Guineensine, pellitorine, brachystamide B, sarmentine, and sermentosine, 5,8-Hydroxy-7-methoxyflavone, Prenylated hydroxybenzoic acid, 4-Nerolidylcatechol, Piperitone, Champor, and Viridiflorol (EO).
