MATERIALS AND METHODS Sections of brain were obtained at post mortem examination and as soon as possible were either frozen or processed. All autopsies were done within 24 hours of the death of the patient. The filtrates were prepared in the manner described elsewhere (1). Some idea of the uniformity of the human brain filtrates was achieved by nitrogen determi nation of samples of each filtrat...

A study on monitoring of nitrogen (N) leaching was conducted in acidsulfate clayey soil in the central region of Thailand. The objective was to measure the N leaching to shallow groundwater from a tropical paddy field to assess the consequences of agricultural management practices. Mass balance approach was used to estimate the contribution of nitrogen fertilizer to the water environment. The N...

Mahl, M. C. (University of Wisconsin, Madison), P. W. Wilson, M. A. Fife, and W. H. Ewing. Nitrogen fixation by members of the tribe Klebsielleae. J. Bacteriol. 89:1482-1487. 1965.-Strains of species of the tribe Klebsielleae were tested for nitrogen fixation by inoculating actively growing cultures into side-arm flasks containing a medium with a growth-limiting quantity of combined nitrogen (2...

The Goshen Swamp, a fourth order blackwater creek in southeastern North Carolina, was clearcut of 130 acres of riparian and seasonally flooded forest in late May through September 1998. Downstream water quality had been monitored monthly for 212 years before the clearcut, during the clearcut, and for two years following the clearcut. The objective of this paper was to test the hypothesis that c...

Nitrogen and organic matter are part of the pollutant causing eutrophication in freshwater. Textiles industry like Endek is main source matter. Tis paper aims to know degradation process Ammonia-Nitrogen (NH3-N) Chemical Oxygen Demand (COD) with ozone pretreatment operated by different DO level activated sludge. There 2 scenarios treatments this study: (R1) without (R2). Wastewater treatment be...

A simple flow injection (FI) conductometric system with gas diffusion separation was developed for the determination of Kjeldahl nitrogen (or proteins) in milk and chicken meat. The sample was digested according to the Kjeldahl standard method and the digest was diluted and directly injected into the donor stream consisting of 4M NaOH. In alkaline medium, ammonium was converted to ammonia, whic...

The efficiency of a series of wetland colonized with Eichhornia crassipes and Salvinia molesta to treat the effluent of a giant river prawn (Macrobrachium rosenbergii) broodstock pond was evaluated in this study. The experimental design was completely randomized and was performed in 9 rectangular tanks (1.6 m3) with three treatments (constructed wetlands) and three replicates. The treatment typ...

Lagoons have been traditionally used in India for decentralized treatment of domestic sewage. These are cost effective as they depend mainly on natural processes without any external energy inputs. This study focuses on the treatment efficiency of algae-based sewage treatment plant (STP) of 67.65 million liters per day (MLD) capacity considering the characteristics of domestic wastewater (sewag...

The increasing solid waste generation rates and their high collection cost were some of the major problems in India. This paper deals with the effective management of Temple wastes. The temple waste consists of coconut, leaves, flowers, fruits etc which are of biodegradable in nature.It also includes milk products, grains and water, which could facilitate the growth of microorganisms. Such biod...
