To provide an appropriate signal, the concept of a "failure" sensor is introduced, in which the output is not necessarily proportional to the input, but is unmistakably affected when an unusual event occurs. The design of this failure sensor is based on the water opacity which can be indicative of an unusual event in a water distribution network. The laboratory work and field trials necessary to design and prove out this type of failure sensor are described here. It is concluded that a low-cost failure sensor of this type has good potential for use in a comprehensive water monitoring and management system based on Artificial Neural Networks (ANN).

Presently, as there seems little prospect of early detection of this cancer, an understanding of the etiological factors may suggest opportunities for its primary prevention. In this paper, we have tried to determine the role of diet and other life-style related factors in the etiology of cancer of esophagus. MATERIAL AND METHODS: A total of 100 confirmed squamous cell carcinoma of esophagus patients were enrolled for the study (Group A). 100 healthy subjects were included as controls (Group B). A predesigned questionnaire dealing with the basic patient data, dietary and smoking habits etc. was distributed among the cases in both groups. The data was thoroughly analyzed to define an association with the development of cancer of esophagus. RESULTS: Group A patients included 71 males and 29 females in the age range of 40-70 years. Majority 37% were farmers, 29% house wives. Of the 72% smokers, 66% smoked hookah. 29% had positive family history. More than 90% took salt-tea at breakfast. Meat consumption was low, 44% took it weekly and 42% on monthly basis. 69% took fish yearly. Group B included 75 males and 25 females of which 35.7% were hookah smokers. CONCLUSION: Poor socio-economic status resulting in fewer intakes of fresh fruits, vegetables and fish in addition to heavy hookah smoking are suspected to be the major risk factors for the development of esophageal cancer.

Cross sectional, observational study. One thousand two hundred and four students from the six medical/dental colleges of Karachi participated in the study. The present study was conducted during April and May of the year 2007. The questionnaire consisted of personal questions like gender, field of study, name, and year of study; smoking habits, frequency and place of smoking, attitude and knowledge about diseases developed due to shisha smoking. Chi-square test was used to find relationship between independent variables i.e. field of study medical/ dental], and year of study 1st], 2nd], 3rd], 4th] and final year] with response variables. The mean age of the participants was 20.2 +/- 1.6 years. Two hundred and seventy three students 22.7%] indicated that they smoke shisha. One hundred and nineteen of the male students 41.2%] and 154 female students 16.8%] indicated positively for shisha smoking. Dental students showed 13% higher prevalence of shisha smoking than medical students p<0.0001]. Eighty percent of respondents selected either restaurants or 'shisha bar' for the place of smoking. Sixty four percent of the respondents were influenced by their friends to adopt this habit. Eighty one percent of the respondents admitted that shisha smoking was harmful. Twenty eight percent of the respondents believed an association between shisha smoking and cancer, and about a quarter related it with heart diseases. Thirty eight percent of the shisha smokers were also involved in cigarette smoking. High prevalence of shisha smoking was observed among medical and dental students. However, most of them had adopted this habit as leisure and for socialization. The awareness about the health hazards due to shisha smoking is needed as an intervention to extricate them from this habit Descriptors Humans, Male, Female, 13 - 19 YEARS, ABO Blood-Group System - 45 YEARS, Smoking, Health Knowledge, Attitudes, Practice, Students, Medical, Cross-Sectional Studies, Students, Dental, Tobacco Use Disorder, Prevalence Links http://pesquisa.bvsalud.org/ghl/resource/en/emro-97334 Book Title Database GHL; http://www.globalhealthlibrary.net/ Publisher Data Source Authors Khan,Nazeer, Siddiqui,Muhamad Umer, Padhiar,Adnan Ahmed, Hashmi,Syed Affanul Haq, Fatima ,Saba, Muzaffar,Sania Original/Translated Title URL Date of Electronic PMCID Editors

Further evaluation of these parameters were performed using Cast Iron Pipe Research Association (CIPRA) soil test method. It was inferred that CIPRA method works accurately in tropical Indian conditions in locating the 'sensitive' sites and these parameters, electrical resistivity and redox potential are dominating parameters in causing corrosion to the buried water pipelines. The electrical resistivity was found to be inversely proportional to the moisture content of the soil causing more corrosive environment.

Radiological hazards of Narghile (hookah, shisha, goza) smoking: activity concentrations and dose assessment	2008		Read more...
Source Type Print(0) Ref Type Journal Article Periodical, Full J Environ Radioact Periodical, Abbrev. J.Environ.Radioact. Pub Date Free Form Volume 99 Issue 12 Start Page 1808 Other Pages 14 Notes ID: 18768240 Place of Publication ISSN/ISBN Accession Number Language en SubFile DOI Output Language Unknown(0) PMID Abstract Narghile (hookah, shisha, goza, "water-pipe") smoking has become fashionable worldwide. Its tobacco pastes, known as moassel and jurak, are not standardized and generally contain about 30-50% (sometimes more) tobacco, molasses/juice of sugarcane, various spices and dried fruits (particularly in jurak) and, in the case of moassel, glycerol and flavoring essences. Tobacco contains minute amounts of radiotoxic elements such as (210)Pb, (210)Po and uranium, which are inhaled via smoking. Only very few data have been published on the concentrations of natural radionuclides in narghile tobacco mixtures. Consequently, the aim of this study was to draw first conclusions on the potential hazards of radioactivity in moassel tobacco in relation to narghile smoking. The results indicate the existence of a wide range in the radioactivity contents where the average (range) activity concentrations of (238)U, (234)Th (226)Ra, (210)Pb, (210)Po, (232)Th and (40)K, in Bq/kg dry weight were 55 (19-93), 11 (3-23), 3 (1.2-8), 14 (3-29), 13 (7-32), 7 (4-10) and 719 (437-1044)Bq/kg dry weight, respectively. The average concentrations of natural radionuclides in moassel tobacco pastes are comparable to their concentration in Greek cigarettes and tobacco leaves, and lower than that of Brazilian tobacco leaves. The distribution pattern of these radionuclides after smoking, between smoke, ash and filter, is unknown, except for (210)Po during cigarette smoking and from one existing study during moassel smoking. Radiological dose assessment due to intake of natural radionuclides was calculated and the possible radio-toxicity of the measured radionuclides is briefly discussed.

Pub Date Free Form 1991/ Volume 11 Issue 2 Start Page 135 Other Pages 140 Notes Place of Publication ISSN/ISBN 0256-4947 Accession Number Language SubFile DOI Output Language Unknown(0) PMID Abstract The effect of jurak smoke condensate on the activities of alkaline phosphatase, glucose 6-phosphatase, 5'-nucleotidase, and cholinesterase of mouse liver and small intestine was investigated. Jurak smoke condensate was administered orally by stomach tube five times weekly over a three-month period. Fifteen animals were used at 1, 2, and 3 months after the start of the administration, with 5 animals killed on days 1, 5, and 9, and the liver and small intestine removed for enzyme assays. The activities of all four enzymes, which are known to be sensitive to toxic agents, were significantly affected. These results indicate that the low content of tobacco leaves in jurak paste and the filtration of the smoke by water in the sheesha reservoir are not sufficient to make the smoke inhaled by smokers risk free.

Capital costs (replacement, rehabilitation and repairing costs), benefits (by the reduction of pumping cost and leakage cost), and hydraulic reliability are used for making an optimal decision for the rehabilitation plan of a water pipe network. KYPIPE is used for checking the hydraulic reliability. A multi-objective optimization model is successfully developed in this study. And the task is tackled using a new meta-heuristic algorithm, Harmony Search, for solving a large optimization problem to which conventional optimization techniques are poorly suited. Five different models with different objective functions are developed and tested according to various conditions considered in this study. These models provide more options for the rehabilitation of pipe network systems compared to previously suggested models in the literature.

Forensic autopsies were carried out on three of the four men, who died soon after the incident. From autopsy findings, the cause of death was diagnosed to be suffocation after aspirating seawater in the three victims. To clarify why the men fell into the lake, a chemical analysis for hydrogen sulfide was carried out using the extractive alkylation technique combined with gas chromatography/mass spectrometry. The sulfide was detected as its derivative, bis(pentafluorobenzyl)sulfide, in body tissues taken from all the victims, and the concentration of hydrogen sulfide gas at the scene was estimated as having been nearly fatal.
