State assets of public water pipelines and sewerage were transferred to towns and municipalities and joint stock companies were established. Two types of companies appeared-operational and ownership companies. The first type is the operational company that operates the infrastructure assets of public water pipelines and sewerage. These assets stay in the ownership of municipalities. A long term operational contract is agreed that solves the relationship between the owners and operators. The second type is the ownership company that directly owns the infrastructure assets of public water pipelines. Towns and municipalities in this case became shareholders of those companies. At the end of nineties, big international companies bought shares of both operational and ownership companies. Municipalities have to, by law, ensure the operation of public water pipelines. However, by the sale of shares they have lost a possibility to participate in decision making. A question about future co-operation between towns and municipalities and ownership companies appears. An example of the North Moravian Water and Sewerage Works Company was used to describe a possible way of co-operation between a private company and the municipalities on whose territory the company operates. Contracts between the ownership company and particular municipalities were agreed. This solution turned out to be complicated, so the municipalities affiliated and established Water Management Association. The objective of the Association is to promote common interests of the municipalities in relation to the water company. A contract was agreed between the Water Management Association and the company about co-operation in the area of water tariff setting and public waterworks' development.

Cases were 151 males with incident, histologically confirmed invasive cancer of the bladder, and controls were 157 males admitted to hospital for acute, non-neoplastic, non-urinary tract, non-smoking-related conditions. With reference to never smokers, ex-smokers had a multivariate odds ratio (OR) of 4.4 [95% confidence interval (Cl) 1.7- [1.7] and current smokers of 6.6 (95% Cl 3.1-13.9). The ORs were 5.4 for 40 years), and inversely related to age at starting (OR of 8.8 for starting <20 years), and inversely related to time since quitting smoking. Compared with never smokers who did not report a clinical history of schistosomiasis, the OR was 9.4 for smokers with a history of schistosomiasis, and 10.7 for smokers ever employed in high-risk occupations compared with non-smokers not reporting such a history. Thus, our results, while not giving indications of an increased bladder cancer risk with habits other than cigarette smoking, found a remarkably strong association with various measures of cigarette smoking that could explain 75% of bladder cancer cases among males from Alexandria. The prevalence of smoking was very low among women, and consequently tobacco was not a relevant risk factor for female bladder cancer.

Production and release of microbial cells by the biofilm affect microbial levels in the water column and in some cases this fact constitutes a public health concern. In this study, we attempt to analyze in which way the existence of different episodes of chlorine depletion affects both biofilm formation and microbial load of an artificial laboratory system. The work was carried out using two parallel packed bed reactors both supplied with running tap water. One of the reactors was used as a control and was permanently exposed to the action of chlorine. In the other reactor, chlorine was neutralized at selected times during the experiment and for periods of variable length. During the experiment the concentration of total and viable cells from the effluent was monitored at the exit of each of the reactors. The data obtained were used to estimate microbial production from the biofilms. As an average, release of microbial cells to the water phase increased tenfold in the absence of chlorine. The results also indicate that disinfectant efficiency against the biofilm was not recovered when chlorine returned to normal levels after each event of chlorine neutralization. Cell viability in the water phase in the presence of chlorine was low at the beginning of the experiment but increased 4 orders of magnitude after five neutralization periods. Therefore, subsequent episodes of chlorine depletion may accelerate the development of microbial communities with reduced susceptibility to disinfection in real drinking water systems.

Pyrolysis of cannabinoids: A model experiment in the study of cannabis smoking	1978	Lab. Organ. Chem., State Univ., Utrecht	Read more...

Pub Date Free Form 1978/ Volume 30 Issue 3 Start Page 55 Other Pages 59 Notes Place of Publication ISSN/ISBN 0007-523X Accession Number Language SubFile DOI Output Language Unknown(0) PMID Abstract Since cannabis products are generally administered by smoking, it is of importance to get a better understanding of the effects of the smoking process on cannabinoids. Several investigators have studied the conversions of cannabinoids during smoking. However, the information available remains limited and even contradictory. Several reasons can be indicated for this discrepancy. The pyrolytic products of the cannabinoids are masked by the bulk of the substrate which is smoked. On the other hand, a relative change in the composition of the cannabinoids after smoking does not necessarily implicate a mutual conversion, which is however, a conclusion generally observed in literature. Moreover, the experimental techniques used by different research groups are very diverse: except for the material which is to be smoked and which is subject to large variations (marijuana, hashish, cannabis extracts mixed with tobacco, which is often pre-treated), the smoking-techniques also differ to a great extent (e.g., cigarette, pipe, water-pipe). The only common feature of these techniques is that cannabis is subjected to a thermal treatment. This situation calls for additional, more fundamental insight into the processes taking place during the smoking of cannabinoids. It was hoped that comparison of the products formed by smoking cannabidiol (I, CBD) through a water-pipe which is the general way of smoking by heavy cannabis users in the eastern countries, and the products formed by treatment of CBD under several pyrolytic conditions may contribute to reach this goal.

The studied variables were extraction solvent type and volume, disperser solvent type and volume, aqueous sample volume and temperature. The optimum experimental conditions of the proposed DLLME method were: a mixture of 10 microL tetrachloroethylene (extraction solvent) and 1 mL acetone (disperser solvent) exposed for 30 s to 10 mL of the aqueous sample at room temperature (20 degrees C). Centrifugation of cloudy solution was carried out at 2300 rpm for 3 min to allow phases separation. Finally, 2 microL of extractant was recovered and injected into the GC-MS instrument. Under the optimum conditions, the enrichment factors ranged between 46 and 316. The calculated calibration curves gave a high-level linearity for all target analytes with correlation coefficients ranging between 0.9967 and 0.9999. The repeatability of the proposed method, expressed as relative standard deviation, varied between 5% and 15% (n=8), and the detection limits were in the range of 1-25 ng L(-1). The LOD values obtained are able to detect these OCPs in aqueous matrices as required by EPA methods 525.2 and 625. Analysis of spiked real water samples revealed that the matrix had no effect on extraction for river, surface and tap waters; however, urban wastewater sample shown a little effect for five out of eighteen analytes.

A two-stage multivariate optimization approach has been developed employing a Plackett-Burman design for screening and selecting the significant factors involved in the USA-DLLME procedure, which was later optimized by means of a circumscribed central composite design. The optimum conditions were: extractant solvent volume, 13 microL; solvent type, chlorobenzene; sample volume, 13 mL; centrifugation speed, 2300 rpm; centrifugation time, 5 min; and sonication time, 2 min. Under the optimized experimental conditions the method gave levels of repeatability with coefficients of variation between 10 and 24% (n=7). Limits of detection were between 0.002 and 1.4 microg L(-1). Calculated calibration curves gave high levels of linearity with correlation coefficient values between 0.991 and 0.9997. Finally, the proposed method was applied for the analysis of wastewater samples. Relative recovery values ranged between 71 and 116% showing that the matrix had a negligible effect upon extraction. To our knowledge, this is the first time that combines LLME and GC-MS for the analysis of methylsiloxanes in wastewater samples.

However, the catheters are subject to be altered by Candida biofilms which increase the risk of invasive nosocomial infections due to the high resistance to antifungal agents. Therefore, the minimum inhibitory concentrations of planktonic (MIC) and sessile cells (CIMS) were evaluated. METHODS: To review the in vivo biofilms structures of Candida sp. formed on the inner and/or external surfaces of collected catheters, we used scanning electron microscopy (SEM). The level of biofilm resistance was assessed against two conventional antifungal agents: amphotericin B (AmB), which belongs to the class of polyenes, and fluconazole (FLZ) which is an azole. RESULTS: The SEM observation of biofilms of Candida sp. reveals complex structures. Compared to MICs, the calculation of CIMS showed an increase of 32 times with AmB and of 128 times with FLZ. CONCLUSION: Catheters offer an ideal surface to Candida sp. to form biofilms. This complex structure induces the increase of the resistance of sessile cells against two antifungal agents, AmB and FLZ.

Our results demonstrate that DGGE fingerprinting and rRNA quantification should allow workers to precisely and rapidly characterize the microbial assemblage in a spontaneous lactic acid fermented food. Lactic acid bacteria (LAB) accounted for 90 to 97% of the total active microflora; no streptococci were isolated, although members of the genus Streptococcus accounted for 25 to 50% of the microflora. Lactobacillus plantarum and Lactobacillus fermentum, together with members of the genera Leuconostoc and Weissella, were the other dominant organisms. The overall activity was more important at the periphery of a ball, where eucaryotes, enterobacteria, and bacterial exopolysacharide producers developed. Our results also showed that the metabolism of heterofermentative LAB was influenced in situ by the distribution of the LAB in the pozol ball, whereas homolactic fermentation was controlled primarily by sugar limitation. We propose that starch is first degraded by amylases from LAB and that the resulting sugars, together with the lactate produced, allow a secondary flora to develop in the presence of oxygen. Our results strongly suggest that cultivation-independent methods should be used to study traditional fermented foods.

The TTGE technique reveals differences in the 16S rDNA V6-V8 regions of these bacteria. DNA was extracted directly from sourdough samples. A specific TTGE fingerprint was determined for 30 bacterial species, including members of the genera Lactobacillus, Leuconostoc and Weissella, all known to be present in sourdough. These sourdoughs contain different species of lactic acid bacteria (LAB) depending on ecological conditions prevailing in the different sourdough fermentations. Only a few LAB species were found to be competitive and became dominant. Lactobacillus sanfranciscensis was observed as the most frequently found species. In sourdough GO, L. sanfranciscensis, Lactobacillus panis and two new species, Lactobacillus nantensis and Lactobacillus hammesii, were detected. Sourdough BF contain L. sanfranciscensis, Lactobacillus spicheri and Lactobacillus pontis. In sourdough VB, which differed in the process temperature, we identified exclusively L. sanfranciscensis and Leuconostoc mesenteroides subsp. mesenteroides. Lactobacillus frumenti, L. hammesii and Lacobacillus paralimentarius became the predominant species in sourdough RF. Compared with conventional bacteriological methods, the use of this new molecular approach to analyze the sourdough ecosystem should therefore allow a more complete and rapid assessment of its specific microbiota.
