13. Development of a new process to produce of fatty acids ethyl esters (biodiesel) from castor oil / DESENVOLVIMENTO DE UM NOVO PROCESSO PARA A PRODUÇÃO DE BIODIESEL ETÍLICO DE MAMONA
The present work seeks study the production of fatty acids ethyl esters from Ricinus communis L. by alkaline transesterification of castor oil with ethanol. This methodology will be used to determine the optimum conditions for biodiesel production from castor oil using the minimal number of unit operations with the consequent benefit from economical point of

14. Simplified Gas Chromatographic Procedure for Identification of Bacterial Metabolic Products
A rapid and simple procedure is described for analysis of fermentation products from anaerobic bacteria grown in glucose broth. A 1-ml sample of the culture is drained through cation-exchange resin in a Pasteur pipette. The effluent fluid is directly analyzed isothermally in a gas chromatograph for volatile fatty acids (C2 to C6) as well as for lactic, pyruv

15. Use of prototype automated blood culture system and gas-liquid chromatography for the analysis of continuous ambulatory peritoneal dialysis associated infection.
AIMS: (1) To compare the recovery of organisms from continuous ambulatory peritoneal dialysis (CAPD) effluent fluid obtained from patients with clinical evidence of peritonitis, with an automated system (AS) and the Septichek blood culture system; (2) to evaluate the times to detection of organisms with the two systems; (3) to identify anaerobes from CAPD sa

16. High-Rate Anaerobic Treatment of Wastewater at Low Temperatures
Anaerobic treatment of a volatile fatty acid (VFA) mixture was investigated under psychrophilic (3 to 8°C) conditions in two laboratory-scale expanded granular sludge bed reactor stages in series. The reactor system was seeded with mesophilic methanogenic granular sludge and fed with a mixture of VFAs. Good removal of fatty acids was achieved in the two-sta

17. Evidence for a Role of Free Fatty Acids in the Regulation of Somatostatin Secretion in Normal and Alloxan Diabetic Dogs
To investigate the effect of acute elevation of plasma free fatty acids (FFA) on the secretion of splanchnic somatostatin-like immunoreactivity (SLI), the peripheral venous, pancreatic, and gastric venous effluent levels of SLI were measured in normal and chronic alloxan diabetic dogs before and after the infusion of a fat emulsion supplemented with heparin.

18. Metabolites and biodegradation pathways of fatty alcohol ethoxylates in microbial biocenoses of sewage treatment plants.
The biodegradation of fatty alcohol polyglycol ethers was studied by analyzing the 14C-labeled intermediates isolated from the effluent of a model continuous-flow sewage treatment plant after dosage of either alkyl- or heptaglycol-labeled stearyl alcohol ethoxylate (SA-7EO). In each case, uncharged and carboxylated (mainly dicarboxylated) polyethylene glycol

19. Role of p38 in the Priming of Human Neutrophils by Peritoneal Dialysis Effluent
Peritoneal dialysis effluent (PDE) contains a low-molecular-weight substance that is able to prime human neutrophils for the release of arachidonic acid and superoxide anion. Conventional priming agents, such as tumor necrosis factor alpha (TNF-α), are known to signal via mitogen-activated protein (MAP) kinases; at least one possible substrate for MAP

20. Stimulation of Insulin Secretion by Long-Chain Free Fatty Acids. A DIRECT PANCREATIC EFFECT
A continuous-flow centrifuge was used to infuse sodium salts of oleic, linoleic, lauric, or palmitic acid into the pancreatic artery of anesthetized dogs. In these regional perfusion studies there was no increase in FFA levels in the general circulation. Elevation of pancreatic FFA levels produced an immediate increase in pancreatic venous immunoreactive ins

21. Distribution of Oxytetracycline Resistance Plasmids between Aeromonads in Hospital and Aquaculture Environments: Implication of Tn1721 in Dissemination of the Tetracycline Resistance Determinant Tet A
Oxytetracycline-resistant (OTr) mesophilic aeromonads were recovered from untreated hospital effluent (72 isolates) and from fish farm hatchery tanks (91 isolates) at sites within the English Lake District, Cumbria, England. The transfer of OTr plasmids from these isolates was investigated. Using Escherichia coli J53-1 as a recipient, 11 isolates from the ho
