  2. Sanitary engineering and water economy in Europe

    PubMed Central

    Krul, W. F. J. M.

    1957-01-01

    The author deals with a wide variety of aspects of water economy and the development of water resources, relating them to the sanitary engineering problems they give rise to. Among those aspects are the balance between available resources and water needs for various purposes; accumulation and storage of surface and ground water, and methods of replenishing ground water supplies; pollution and purification; and organizational measures to deal with the urgent problems raised by the heavy demands on the world's water supply as a result of both increased population and the increased need for agricultural and industrial development. The author considers that at the national level over-all plans for developing the water economy of countries might well be drawn up by national water boards and that the economy of inter-State river basins should receive international study. In such work the United Nations and its specialized agencies might be of assistance. PMID:13472427

  3. Sanitary engineering aspects of nuclear energy developments*

    Kenny, A. W.

    1962-01-01

    So many developments have taken place in the field of nuclear energy since 1956, when the author's previous paper on radioactive waste disposal was published in the Bulletin of the World Health Organization, that a fresh review of the subject is now appropriate. The present paper deals with those aspects of the problem which are of most interest to the sanitary engineer. It considers specific points in the latest recommendations of the International Commission on Radiological Protection in relation to public drinking-water supplies, and examines the problem of fall-out, with special reference to the presence and significance of strontium-90 in drinking-water. A general survey of the various uses of radioactive materials is followed by a discussion of the legislative and control measures necessary to ensure safe disposal of wastes. The methods of waste disposal adopted in a number of nuclear energy establishments are described in detail. The paper concludes with some remarks on solid waste disposal, siting of nuclear energy industries and area monitoring. PMID:14455214

    2004-01-01

    To support development of the Boeing-Rocketdyne RS84 rocket engine, a full-flow, reaction turbine geometry was integrated into the NASA-MSFC turbine air-flow test facility. A mechanical design was generated which minimized the amount of new hardware while incorporating all test and instrumentation requirements. This paper provides details of the mechanical design for this Turbine Air-Flow Task (TAFT) test rig. The mechanical design process utilized for this task included the following basic stages: Conceptual Design. Preliminary Design. Detailed Design. Baseline of Design (including Configuration Control and Drawing Revision). Fabrication. Assembly. During the design process, many lessons were learned that should benefit future test rig design projects. Of primary importance are well-defined requirements early in the design process, a thorough detailed design package, and effective communication with both the customer and the fabrication contractors.

  8. Development and Testing of an Innovative Two-Arm Focal-Plane Thermal Strap (TAFTS)

    NASA Technical Reports Server (NTRS)

    Urquiza, E.; Vasquez, C.; Rodriguez, J.; Van Gorp, B.

    2011-01-01

    Maintaining temperature stability in optical focal planes comes with the intrinsic challenge of creating a pathway that is both extremely flexible mechanically and highly conductive thermally. The task is further complicated because science-caliber optical focal planes are extremely delicate, yet their mechanical resiliency is rarely tested and documented. The mechanical engineer tasked with the thermo-mechanical design must then create a highly conductive thermal link that minimizes the tensile and shear stresses transmitted to the focal plane without design parameters on an acceptable stiffness. This paper will describe the development and testing of the thermal link developed for the Portable Remote Imaging Spectrometer (PRISM) instrument. It will provide experimentally determined mechanical stiffness plots in the three axes of interest. Analytical and experimental thermal conductance results for the two-arm focal-plane thermal strap (TAFTS), from cryogenic to room temperatures, are also presented. The paper also briefly describes some elements of the fabrication process followed in developing a novel design solution, which provides high conductance and symmetrical mechanical loading, while providing enhanced flexibility in all three degrees of freedom.

  14. Narratives of Public Health in Dickens's Journalism: The Trouble with Sanitary Reform.

    PubMed

    Smith, Ralph F

    2015-01-01

    Although Dickens is still known as having been a highly visible supporter of England's well-known nineteenth-century sanitary movement, he became, in fact, deeply troubled by many of this movement's fundamental tenets, as evidenced by journal narratives on fever that he edited and wrote in the mid-nineteenth century. Rather than water and sewer engineering works and a sanitary regime policed by government agencies as envisaged by Edwin Chadwick and other sanitary reformers, Dickens's view by 1855 was that only a massive erasure of the existing social and political systems and their replacement by an utterly new infrastructure would suffice.

  19. Jonathan Taft: dentistry's great forgotten hero.

    PubMed

    Ring, Malvin E

    2006-01-01

    One of the greatest figures in the development of the dental profession to the high status it enjoys today is all but forgotten. Jonathan Taft was dean of the second dental school in the world and wrote the most important clinical textbook of his time, one that was reprinted in many editions over a quarter of a century. Later appointed dean of the new University of Michigan Dental School, he instituted innovations in admission requirements and course of study that were copied by all subsequent schools and are the standards adhered to today. The editor of one of the most important dental journals for 44 years, a record unmatched to this day, he set the standards for modern dental periodical literature that have done so much to elevate dentistry that today it stands on a par with medicine as a truly science-based profession. He served dentistry in many capacities: president of the American Dental Association, founder of the National Association of Dental Faculties, and founder of the National Association of Dental Examiners. Over his lifetime, he published almost 200 professional papers and probably attended and lectured at more dental meetings than anyone of his day and since. His memory should be resurrected, and the profession must be made aware of the great debt it owes to this intrepid fighter for a better dental profession.

    The purpose of the study was to assess the sanitary-and-hygienic state of solid garbage (SG) burial grounds in the Perm Territory in different stage of a life cycle. This paper presents the results of the study of deposited waste, forming dump soil, and SG ground emissions by general sanitary and sanitary-microbiological parameters and their effect on environmental objects. The performed studies of the sanitary-and-hygienic situation on some grounds of the Perm Territory suggest that there is a need for setting up a system for sanitary-and-monitoring of SG ground and for elaborating engineering, organizational, and prophylactic measures to assure the sanitary-and-hygienic safety of objects and to control the quality and quantity of waste to be buried and the currents of emissions (ground body degassing, filtrating sewage drainage and purification).

    After the Crimean War, Florence Nightingale persisted in researching the health conditions of British troops throughout the Empire. Undaunted by geographic limitations, she surveyed and publicized data that documented the mismanagement of living conditions and health care among the occupational forces on the Indian continent. Nightingale proposed widespread changes in the reporting of military health status and biostatistics, in sanitary engineering, and in self-care activities. With dogged persistence, she continued to gather follow-up data to measure the changing health status of soldiers in a land she never saw.

    PubMed

    Sanli, Senem; Akmese, Bediha; Altun, Yuksel

    2013-01-01

    In this study, ionization constant (pKa) values were determined by using the dependence of the retention factor on the pH of the mobile phase for four ionizable drugs, namely, risperidone (RI), clozapine (CL), olanzapine (OL), and sertindole (SE). The effect of the mobile phase composition on the pKa was studied by measuring the pKa at different acetonitrile-water mixtures in an HPLC-UV method. To explain the variation of the pKa values obtained over the whole composition range studied, the quasi-lattice quasi-chemical theory of preferential solvation was applied. The pKa values of drugs were correlated with the Kamlet and Taft solvatochromic parameters. Kamlet and Taft's general equation was reduced to two terms by using combined factor analysis and target factor analysis in these mixtures: the independent term and the hydrogen-bond donating ability a. The HPLC-UV method was successfully applied for the determination of RI, OL, and SE in pharmaceutical dosage forms. CL was chosen as an internal standard. Additionally, the repeatability, reproducibility, selectivity, precision, and accuracy of the method in all media were investigated and calculated.

    Solvate ionic liquids are a relatively new class of liquids produced by combining a coordinating solvent with a salt. They have a variety of uses and their suitability for such depends upon the ratio of salt to coordinating solvent. This work investigates the Kamlet-Taft solvent parameters of, NMR chemical shifts of nuclei in, and thermoelectrochemistry of a selected set of solvate ionic liquids produced from glymes (methyl terminated oligomers of ethylene glycol) and lithium bis(trifluoromethylsulfonyl)imide at two different compositions. The aim is to improve the understanding of the interactions occurring in these ionic liquids to help select suitable solvate ionic liquids for future applications.

    2014-05-01

    Landfills are among the most common sources of pollution in ground water. Their widespread deployment, prolonged usage and the serious damage they cause to all of the elements of the environment are the reasons, which make the study of the problem particularly relevant. Most dangerous of all are the open dumps used until the middle of the twentieth century, from which large amounts of liquid emissions flowed freely (landfill infiltrate). In recent decades, the problem is solved by the construction of sanitary landfills in which they bury waste or solid residue from waste utilization plants. The bottom and the sides of the sanitary landfills are covered with a protective waterproof screen made of clay and polyethylene and the landfill infiltrate is led outside through a drainage system. This method of disposal severely limits any leakage of gas and liquid emissions into the environment and virtually eliminates the possibility of contamination. The main topic in the conducted hydrogeological study was a quantitative assessment of groundwater pollution and the environmental effects of re-landfilling of an old open dump into a new sanitary landfill, following the example of the municipal landfill of Asenovgrad, Bulgaria. The study includes: 1.A set of drilling, geophysical and hydrogeological field and laboratory studies on: -the definition and designation of the spatial limits of the main hydrogeological units; -identification of filtration parameters and migration characteristics of the main hydrogeological units; -clarifying the conditions for the sustentation and drainage of groundwater; -determininng the structure of the filtration field; -identifying and assessing the size and the extent of groundwater contamination from the old open dump . 2.Mathematical numeric models of migration and entry conditions of contaminants below the bottom of the landfill unit, with which the natural protection of the geological environment, the protective effect of the engineering

  3. Ants avoid superinfections by performing risk-adjusted sanitary care.

    PubMed

    Being cared for when sick is a benefit of sociality that can reduce disease and improve survival of group members. However, individuals providing care risk contracting infectious diseases themselves. If they contract a low pathogen dose, they may develop low-level infections that do not cause disease but still affect host immunity by either decreasing or increasing the host's vulnerability to subsequent infections. Caring for contagious individuals can thus significantly alter the future disease susceptibility of caregivers. Using ants and their fungal pathogens as a model system, we tested if the altered disease susceptibility of experienced caregivers, in turn, affects their expression of sanitary care behavior. We found that low-level infections contracted during sanitary care had protective or neutral effects on secondary exposure to the same (homologous) pathogen but consistently caused high mortality on superinfection with a different (heterologous) pathogen. In response to this risk, the ants selectively adjusted the expression of their sanitary care. Specifically, the ants performed less grooming and more antimicrobial disinfection when caring for nestmates contaminated with heterologous pathogens compared with homologous ones. By modulating the components of sanitary care in this way the ants acquired less infectious particles of the heterologous pathogens, resulting in reduced superinfection. The performance of risk-adjusted sanitary care reveals the remarkable capacity of ants to react to changes in their disease susceptibility, according to their own infection history and to flexibly adjust collective care to individual risk.

    The article considers activity of municipal self-governments of Russia concerning support of sanitary epidemiological well-being of cities in the late XIX--early XX centuries. The acuteness of problem of sanitary conditions of urban settlements particularly became visible in post-reform period due to increasing of number of urban population, alteration of setup and rhythm of life in cities, appearance of new forms of worker's daily chores. Al this, against the background of underdevelopment of communal sphere aggravated epidemiological situation in cities. The impulse to improvement and development of sanitary control was made by the city regulations of 1870 presenting to town authorities the right to deal with sanitary issues. The significant input into improvement of cities was made first of all at the expense of construction of water supplies and sewerage and support of sanitary control of these spheres of municipal economy. Under town councils of many cities the sanitary commissions were organized to support permanent sanitary control in town. The development of town sanitation followed the way of specialization. The housing and communal, trade and food, school and sanitary and sanitary and veterinary control were organized.

    PubMed

    Berner, Włodzimierz

    2006-01-01

    At the time of the Second Republic of Poland, Warsaw, the capital of the rebirth country, was a neglected town as regards sanitary conditions. The genesis of this situation dates back to the period of the national bondage by the Russian partitioner, and since 1915 by the German invader who did not care about the problems associated with public health. The sanitary and hygienic conditions worsened significantly in 1916, after incorporating into Warsaw large out-of-town regions whose housing was of the rural character with numerous wooden cottages, field roads, without any sanitary sewage system. Poor municipal sanitary-maintenance conditions and infectious diseases spreading in Warsaw made the Town Authorities implement preventive action and entrust sanitary surveillances with this difficult task. These surveillances were set up at the time of the First World War, and after 1920 were changed into sanitary offices. Their duties included control of acute infectious diseases, sanitary inspection of living quarters, sites of production and selling of food articles, plants, service outlets, shops of a different character, as well as surveillance of food purchased by the inhabitants. In each sanitary office a doctor was employed who supervised the work of one, two or three sanitary inspectors.

    Information about the quality of rural drinking water sources can be used to manage their safety and mitigate risks to health. Sanitary surveys, which are observational checklists to assess hazards present at water sources, are simpler to conduct than microbial tests. We assessed whether sanitary survey results were associated with measured indicator bacteria levels in rural drinking water sources in Kisii Central, Kenya. Overall, thermotolerant coliform (TTC) levels were high: all of the samples from the 20 tested dug wells, almost all (95%) of the samples from the 25 tested springs, and 61% of the samples from the 16 tested rainwater harvesting systems were contaminated with TTC. There were no significant associations between TTC levels and overall sanitary survey scores or their individual components. Contamination by TTC was associated with source type (dug wells and springs were more contaminated than rainwater systems). While sanitary surveys cannot be substituted for microbial water quality results in this context, they could be used to identify potential hazards and contribute to a comprehensive risk management approach.

    The scientific rationale for preventive measures based on sanitary-and-epidemiological surveillance on environmental objects is considered. The sizes of functional zones and space for various types of communal services and amenities and leisure are regulated to ensure good urban vital activities. Multistorey housing causes an increase in the number of negative factors per area units and in their impact on health. A proposal has been made for the standardization of the ranges of urban population upsurge and size, by using the sanitary-and-hygienic rules and norms rather than climatic parameters. A criterion system for assessing the data of statistical observations has been substantiated and 5 levels of analysis and managerial decision-making have been proposed. Cause-and-effect relations may be determined for the parameters of the second level; models of program-oriented studies for the third level, only sanitary-and-epidemiological surveillance is possible for the fourth and fifth levels. The space planning scheme must provide for water supply reserves, generation areas for pure air coming into the town, and waste disposal areas. The general layout may use statistical observation parameters characterizing the second level of occurrence of negative phenomena. The statistical observation parameters characterizing the third and fourth levels of occurrence of negative phenomena may be used for municipal improvements and sanitary maintenance. These characterizing the fourth and fifth level may be used for prevention in therapeutic-and-prophylactic institutions.

    Approximately 30,000 sanitary landfills were in operation in the United States in 1976; today, there are <7,000. The remaining 23,000 closed sites can be reclaimed to actually enhance the surrounding community; cost is the only limiting factor. Abandoned sanitary landfill sites do have problems, namely leachates, methane build-up, and subsidence. However, with modern techniques and planning, these problems can be overcome. Across the nation, old landfills have been converted into golf courses, parks, ski resorts, libraries, and even methane power plants. In some cases, a community's property value has actually increased after reclamation of the local landfill. Shelby County, inmore » southwestern Tennessee, currently has four closed sanitary landfills. Only one site has been fully utilized as a recreational facility. At this site, four soccer fields are home to over 150 league soccer teams. Two sites are home to airplane radio-control clubs, although most land at these sites is currently unused. The fourth site is completely unused and up for sale. All of these closed sanitary landfills have potential use as recreation areas, but, as is often the case, lack of money and initiative is preventing development. 7 refs.« less

The above project was carried out through proper quality control of foods, drinking water as well as a definite care of personal hygiene of all those involved in the catering business (132 restaurants were included). The mentioned report informs only of the work of the National Public Health Laboratory in the Sanitary Epidemiological Program. The following products were analyzed: 133 water samples, 272 animated and nonliving surfaces, and 399 foods. Twenty seven percent of water samples were rejected, as well as 85% of the different surfaces and 60% of the food samples. High counts of mesophilic aerobics, followed by coliforms, S. aureus and Salmonella sp., were the principal specimens encountered. Therefore, it was suggested the permanent development of a sanitary epidemiological program.

    This paper analyzes the Brazilian Sanitary Surveillance System as an arrangement aimed at regulating and reducing health risks associated with consumption of products, use of health services and the environment. Historical, political and tax aspects were considered and their development compared with the National Health Surveillance System, which has received strong international cooperation. The comparison was based on the trajectory of their national systems and related federal agencies, as well as on criteria adopted for decentralization. The central category of analysis is federative coordination and was based on the framework of federalism and intergovernmental relations. The institutional context of health and sanitary surveillance presents strong political competition, instability in the project and probable reduction of the ability of federal coordination after the Pact for Health. The National Sanitary Surveillance System due to its nature of public good and high externality in its field of action requires federal coordination for increasing the regional and local cooperation, also because of the structural heterogeneity of Brazilian municipalities.

  2. Sanitary quality of the Jordan River in Salt Lake County, Utah

    USGS Publications Warehouse

    Thompson, K.R.

    1984-01-01

    This investigation of the sanitary quality of the Jordan River was conducted from July 1980 to October 1982 using indicator bacteria rather than specific pathogens. A serious sanitary problem was identified. Concentrations of total coliform bacteria often exceeded 5,000 colonies per 100 milliliters and concentrations of fecal coliform bacteria often exceeded 2,000 colonies per 100 milliliters in the lower reaches of the river. At times these levels were greatly exceeded. The most conspicuous aspect of the bacteriological data is its extreme variability. Seven waste-water treatment plants, seven major tributaries, numerous storm conduits, irrigation-return flow, and other sources all contribute to the dynamic system that determines the sanitary quality of the river. Because of this variability the sanitary quality of the river cannot be predicted at any one time. In general, concentrations of all three indicator bacteria increased in a downstream direction. Storm runoff from urban areas contributed large concentrations of indicator bacteria to the river. Regression analysis of 9 years of data collected at 1700 South Street showed a significant positive correlation between both fecal coliform and fecal streptococcal concentrations versus time. Concentrations of fecal coliform and fecal streptococci have both been increasing since 1974 at 1700 South Street. (USGS)

    The consumption of street food is an economical and practical alternative for the population. However, concerns regarding the safety of these foods are increasing. Thus, this study aimed to analyze the hygienic and sanitary conditions of the street food trade in Uberaba in the State of Minas Gerais. For this purpose, 30 street vending sites were evaluated using a structured questionnaire and microbiological analysis of food handlers' hands and food contact recipients and surfaces. The findings showed low adequacy of street food regarding hand hygiene and food contact surfaces. With respect to surfaces, the results for mesophilic aerobic microorganisms revealed that only 23.3% had satisfactory sanitary conditions. The level of contamination of hands by fecal thermotolerant coliforms and/or Coagulase positive Staphylococci was unsatisfactory in approximately 47% of food handlers. The conclusion drawn is that the hygienic and sanitary conditions of food handlers in Uberaba are poor. It is therefore necessary to adopt effective and permanent training programs on food safety for food handlers urgently.

    While more attention has been paid in recent years to urban point source pollution control through the establishment of wastewater treatment plants in many developing countries, no considerable planning nor any serious measures have been taken to control urban non-point source pollution (urban stormwater runoff). The present study is a screening analysis to investigate the pollution loads in urban runoff compared to point source loads as a first prerequisite for planning and management of receiving water quality. To compare pollutant loads from point and non-point urban sources, the pollutant load is expressed as the weight of pollutant per hectare area per year (kg/ha.year). Unit loads were estimated in stormwater runoff, raw sanitary wastewater and secondary treatment effluents in Isfahan, Iran. Results indicate that the annual pollution load in urban runoff is lower than the annual pollution load in sanitary wastewater in areas with low precipitation but it is higher in areas with high precipitation. Two options, namely, advanced treatment (in lieu of secondary treatment) of sanitary wastewater and urban runoff quality control systems (such as detention ponds) were investigated as controlling systems for pollution discharges into receiving waters. The results revealed that for Isfahan, as a low precipitation urban area, advanced treatment is a more suitable option, but for high precipitation urban areas, urban surface runoff quality control installations were more effective for suspended solids and oxygen-demanding matter controls, and that advanced treatment is the more effective option for nutrient control.

    Chemical analysis and an in vitro approach were performed to assess elemental composition and genotoxic effects of the samples of landfill leachate taken from Lokva Vidotto sanitary landfill the official landfill for Rovinj town, Croatia. Two samples of landfill leachate were collected and analyzed in order to evaluate macro, micro and trace elements by atomic absorption spectroscopy, energy dispersive X-ray spectrometry and colorimetry. Genotoxicity of sanitary landfill leachate was evaluated in human lymphocytes by the use of the micronucleus test and comet assay. Samples were characterized with relatively low concentrations of heavy metals while organic component level exceeded upper permissible limit up to 39 times. Observed genotoxic effects should be connected with high concentrations of ammonia nitrogen, which exceeded permissible limit up to 180 times. Leachate samples of both sanitary landfills increased the frequency of micronuclei, nucleoplasmic bridges and nuclear buds. Increase of DNA damage in human lymphocytes was also detected by virtue of measuring comet assay parameters. All parameters showed statistically significant difference compared to negative control. Increased micronucleus and comet assay parameters indicate that both samples of sanitary landfill leachate are genotoxic and could pose environmental and human health risk if discharged to an aquatic environment.

    Sanitary conditions are essential for the production of meals and control of the presence of pathogensis important to guarantee the health of customers. The aim of this study was to evaluate the sanitary quality of food services by checking the presence of thermotolerant coliforms, Staphylococcus sp. and evaluate the toxigenic potential from the latter. The analysis was performed on water, surfaces, equipment, ready-to-eat foods, hands and nasal cavity of handlers in seven food services. The water used in food services proved to be suitable for the production of meals. Most food, equipment and surfaces showed poor sanitary conditions due to the presence of thermotolerant coliforms (60.6%). Twenty-six Staphylococcus species were identified from the 121 Staphylococcus isolates tested. Staphylococci coagulase-negative species were predominant in the foods, equipment and surfaces. In food handlers and foods, the predominant species was Staphylococcus epidermidis. Twelve different genotypes were found after PCR for the classical enterotoxin genes. The seb gene (19.8%) was the most prevalent among all Staphylococcus sp. Both coagulase-positive and coagulase-negative Staphylococci showed some of the genes of the enterotoxins tested. We conclude that there are hygienic and sanitary deficiencies in the food services analyzed. Although coagulase-positive Staphylococci have not been present in foods there is a wide dispersion of enterotoxigenic coagulase-negative Staphylococci in the environment and in the foods analyzed, indicating a risk to consumer health.

    The international experience gained during the past two centuries indicates that the most efficient and rational way to ensure the protection of the territories occupied by the therapeutic and health-promotion facilities, spa centres, and health resorts together with their natural medical resources is to set up sanitary (mountainous sanitary) protection districts or zones along the perimeter of these territories. Beginning from 2000, numerous changes and amendments have been annually introduced in the Russian legislation intended to ensure efficacious control over the rational exploitation of the territories of therapeutic and health-promotion value and their natural medical resources. These initiatives have negative effect on the activities of these organizations and the quality of the services they are expected to provide. Taken together these effects lead to the degradation of the spa and health resort business. Bearing in mind the current conditions for economic activities, it is proposed, in contrast to the former global approach, to envisage in the aforementioned projects the establishment of the sanitary (mountainous sanitary) protection districts or zones and determine their borders based on the results of the assessment of their potential for the protection of therapeutic factors and other valuable resources. Equally important is the maximum reduction of the areas of the second and third zones taking into account their relevant objective characteristics. In certain cases, the protective district may coincide with the second zone. As far as the federal health resorts and large territories of special health-promotion value are concerned, some of them may have two or more sanitary (mountainous sanitary) protection districts. Both the owners and the users of these territories should be provided the necessary and sufficient possibilities for the rational nature use at the grounds and in the adjacent water areas suitable for the development of health resort

    The U.S. Army Corps of Engineers and the Metropolitan Water Reclamation District of Greater Chicago regulate flows through control structures along the Lake Michigan lakefront and the Chicago Sanitary and Ship Canal (CSSC) for Lake Michigan diversion accounting, flood control, sanitary, and navigation purposes. This report documents the measurement and computation of flow through the Lockport Controlling Works (LCW) and the Lockport Powerhouse. This analysis aided in evaluation of the ratings at both structures, and the development of new ratings at the controlling works. The LCW structure consists of seven 30-feet (ft) wide sluice gates and is used to divert water from the CSSC and into the Des Plaines River. The flow regimes for the sluice gate included both free and submerged weir. Forty and 491 flow values from U.S. Geological Survey streamflow-gaging stations were used to develop equations describing free- and submerged-weir flow, respectively, through the sluice gates. The equations were developed for canal headwater elevations ranging from -7.0 to -10.5 ft Chicago City Datum (CCD), and tailwater (Des Plaines River at Lockport) to headwater (CSSC-LCW-Base) ratios ranging from 0.31 to 0.66. The Lockport Powerhouse structure consists of nine 9-ft wide by 14-ft high sluice gates and two 10-ft diameter turbines. Both tailwater and no-tailwater effect flow regimes occurred during nine measurements. Also, the canal headwater elevations ranged from -2.74 to -8.45 ft CCD, and the gates were configured six different ways during the measurements.

    To establish a scientific foundation for cosmetic supervision and administration based on the analysis of the sanitary quality of cosmetics in Hunan Province during 2010. According to Cosmetic Sanitary Standards (set by the Ministry of Health, People's Republic of China), 150 random samples of cosmetics in Hunan were assayed both for microbial items (including total plate count, fungus and yeast, fecal coliform, staphylococcus aureus, pseudomonas aeruginosa) and chemical items (including 17 kinds of prohibited substances and 14 kinds of restricted substances). The total rate of cosmetics failing to meet the standards was 22.0% of the 150 samples; specific rates for failing perfumes, skin care products (eye cream) and deodorant products were, relatively, 70.6%, 60.00%, and 44.4%. Four kinds of prohibited substances, including diethyl phthalate, acrylamide, asbestos and neodymium, as well as 2 kinds of restricted substances, including triclosan and formaldehyde, were found to exceed standards. None of microbial items exceeded standard levels. The sanitary quality control of cosmetics is lax. Administrative departments should not only reinforce their post-production supervision with respect to cosmetics, but also consolidate their control over the process of cosmetic production in order to solve the problem of toxic residues or illegal and intentional adulterations.

    This baseline study aims to find out the evaluation of hygienic-sanitary conditions at the level of dental medicine cabinets through the verification of certain hygienic aspects. The study conducted consists in monitoring the hygienic/sanitary conditions at the level of 68 dental medicine cabinets (40 private cabinets and 28 school/university dental cabinets in Iasi county), using sheets for the assessment of the hygienic/sanitary conditions adapted from the control sheets of existing dental medicine cabinets at the level of DSP (Public Health Department) Iasi. The sheets for the assessment of the hygienic/sanitary conditions were evaluated by a specialized team and the results were i llustrated in the specific charts. At the level of all the dental cabinets the study revealed nonconformities regarding the means to carry out cleaning, disinfection operations, including the management of perilous waste, the control of medical personnel. An optimization of the hygienic-sanitary conditions at the level of dental medicine cabinets is still necessary, through participation to the activity of personnel training, who is directly involved in dental medical assistance.

    Urban effluents are rich in nutrients, organic matter, pharmaceuticals and personal care products (PPCPs), pesticides, hydrocarbons, surfactants, and others. Previous studies have shown that oysters Crassostrea gigas accumulate significant levels of linear alkylbenzenes (LABs) in sanitary sewage contaminated sites, but there is little information about its toxicological effects in marine bivalves. The aim of this study was to analyze the transcription of genes in two tissues of C. gigas exposed for 12, 24, and 36 h to LABs or sanitary sewage. Likewise, the activity of antioxidant and biotransformation enzymes was measured in oysters exposed for 36 h in all groups. Oysters exposed to LABs and oysters exposed to sanitary sewage showed different patterns of transcriptional responses. LAB-exposed oysters showed lower level of biological responses than the oysters exposed to sanitary sewage. Despite the ability of the oyster C. gigas to accumulate LABs (28-fold), the data indicate that these contaminants are not the cause for the transcriptional responses observed in oysters exposed to sanitary sewage. Possibly, the biological changes observed in the sanitary sewage-exposed oysters are associated with the presence of other contaminants, which might have caused synergistic, additive, or antagonistic effects. The results show that FABP-like and GST-ω-like messenger RNAs (mRNAs) have a rapid response in tissues of oyster C. gigas exposed to sanitary sewage, suggesting a possible protective response and a role in maintaining homeostasis of these organisms.

    The objective of this study is to create a methodology whereby reductions in off-site odor migrations resulting from operational and design changes in new or expanded sanitary landfills can be evaluated. The Ann Arbor Sanitary Landfill was chosen as a prototype landfill to test a hypothesis for this study. This study is a unique approach to odor prediction at sanitary landfills using surface flux measurements, odor threshold panel measurements, and dispersion modeling. Flux measurements were made at open tipping face, temporary cover, final cover, vents, and composting zones of the Ann Arbor Sanitary Landfill. Surface gas velocities and in-ground concentrationsmore » were determined to allow a quantification of the total and methane gas flow rate. Odor threshold panel measurements were performed to determine the odor intensity in odor units at the corresponding sites. The used the flux and odor panel measurements in the Industrial Source Complex Terrain Model to determine the hourly averaged highest and second highest odor levels at 175 receptors placed at the property boundary and 25 nearby residential locations. Using measured values for velocity, subsurface CH{sub 4} concentration and odor intensity, it was determined that the proposed 1990 operations with a buffer distance of 600 feet provided at least a factor of five protection below 1 o.u. of the odor threshold for all receptors, and dilution protection equal to the historic 1984 operations with a 1,200 feet isolation distance.« less

    2006-01-01

    At the time of the Second Republic of Poland łódź was a city with a very unfavourable sanitary and hygienic situation. It resulted from the long-lasting municipal negligence, dating back to the I World War, which included bad living conditions of the working class, problems with sewers and canalisation, and other shortages associated with the sanitary and maintenance status. All these factors contributed to prevalence of infectious diseases and other health threads. Therefore, the Authorities of łódź were obliged to organise the Sanitary Section at the Department of Public Health. Its executive body, i.e. sanitary surveillances dealt with control of acute infectious diseases, sanitary inspection of living quarters, sites of selling and producing food articles, as well as food surveillance. In each sanitary surveillance a doctor was employed together with a secretary and sanitary inspector subordinated to him.

    Leal, Cristian Oliveira Benevides Sanches; Teixeira, Carmen Fontes de Souza

    2017-10-01

    This is a theoretical essay about the development of the concept of solidarity, a word used in the regulatory framework and in political proposals to reorient the Brazilian Unified Health System (SUS). The methodology consisted of mapping authors addressing human action aspects related to this theme from Durkheim's tradition, linking them to his followers, like Marcel Mauss and authors from the "anti-utilitarianism" movement in social sciences. Solidarity is one way to express a "gift" and appears as a multidimensional action, where duty and freedom, instrumental interest and disinterest interpose and interlace. The planning and execution of sanitary surveillance (VISA) actions requires comprehension of organizational forms and solidary relationship management among agents involved in health risk control, transcending the strongly normative aspect of the prevailing supervision actions. The development of associative actions involving sanitary surveillance professionals, economic agents and consumers, aiming to share the responsibilities in the health risk control of products, services and environments subjected to Sanitary Surveillance action is suggested.

    2010-03-01

    Sanitary landfill leachates are a major environmental problem in South American countries where sanitary landfills are still constructed and appropriate designs for the treatment of these leachates remain problematic. The performance of a lab-scale Gradual Concentric Chamber (GCC) reactor for leachates treatment is presented in this study. Two types of sanitary landfill residuals were evaluated, one directly collected from the garbage trucks (JGL), with high organic strength (84 g COD/l) and the second one, a 6-month-generated leachate (YL) collected from the lagoon of the sanitary landfill in Quito, Ecuador, with an organic strength of 66 g COD/l. Different operational parameters, such as organic loading rate (OLR), temperature, recycling and aeration, were tested. The GCC reactor was found to be a robust technology to treat these high-strength streams with organic matter removal efficiencies higher than 65%. The best performance of the reactors (COD removal efficiencies of 75-80%) was obtained at a Hydraulic Retention Time (HRT) of around 20 h and at 35 degrees C, with an applied OLR up to 70 and 100 g COD/l per day. Overall, the GCC reactor concept appears worth to be further developed for the treatment of leachates in low-income countries.

    Sanitary landfill leachate is one of the major problems arising from disposal of urban waste. Sanitary landfill leachate may, however, have use in agriculture. This study, therefore, aimed to analyze initial plant growth and gas exchange in sunflower seedlings supplemented with sanitary landfill leachate and subjected to drought stress through variables of root fresh mass (RFM), shoot fresh mass (SFM), total fresh mass (TFM), relative chlorophyll content (CL), stomatal conductance (g s ), transpiration rate (E), net photosynthetic rate (A), ratio of internal to external CO 2 concentration (Ci/Ca),water use efficiency (EUA), instantaneous carboxylation efficiency (A/Ci), and electron transport rate (ETR). The experimental design was a completely randomized 2 (irrigated and non-irrigated) × 4 (sand, sand + 100 kg N ha -1 organic fertilizer, sand + 100 kg N ha -1 sanitary landfill leachate, and sand + 150 kg N ha -1 sanitary landfill leachate) factorial with five replicates. Under drought stress conditions, leachate treatment supplemented with 100 kg N ha -1 exhibited higher plant fresh weights than those of the treatment containing 150 kg N ha -1 . Increases in fresh mass in plant treatments supplemented with 100 and 150 kg N ha -1 sanitary landfill leachate were related to higher photosynthetic rates.

    This paper aims to evaluate the hygienic-sanitary conditions of kitchens in philanthropic and public daycare centers in the city of São Paulo using a tool of easy application. Information on the hygienic-sanitary conditions was gathered observing the operational conditions of five public and philanthropic daycare centers in the city of São Paulo. A score was developed for classifying the risks of food contamination. The operational conditions in the kitchens of the studied philanthropic and public daycare centers in the city of São Paulo can result in contamination of the prepared food. Among the most important risk factors for food contamination is the behavior of the workers who handle the food. Training and continuous supervision of the involved personnel are the best and easiest alternatives for assuring the appropriate hygienic-sanitary conditions and quality of the food offered to the children in these daycare centers.

  9. EU Sanitary Regulation on Livestock Disposal: Implications for the Diet of Wolves

    NASA Astrophysics Data System (ADS)

    Lagos, Laura; Bárcena, Felipe

    2015-10-01

    Sanitary and environmental regulations may have indirect effects on the wildlife and ecosystem services beyond their regulatory scope. To illustrate such effects, this paper examines how EU sanitary measures, in conjunction with additional regulations and socio-economic changes, have caused wolf diet to shift in Galicia, northwestern Spain. Prior to the bovine spongiform encephalopathy (BSE) crisis in Europe in 2000, livestock carcasses used to be left on the field and were eaten by scavengers and carnivores. As a result of the BSE crisis, sanitary regulations regarding the disposal of livestock carcasses were introduced. These regulations affected the populations of avian scavengers. We hypothesize that wolf ecology has also been affected by the aforementioned regulations. We analysed wolf diet for the period 2003-2006 and compared the results with those of a previously published study (1974-1978). We found a shift in wolf feeding habits following the implementation of these EU regulations. A decrease in carrion consumption was registered, and wolves increased their feeding on the rising population of wild ungulates, especially on roe deer, and on wild pony. Future regulations should assess their potential indirect effects in the early stages of drafting to allow for the design of proper mitigation measures.

    At the beginning of the First World War the most typical diseases in the Russian Army were typhoid, typhus, diphtheria, cholera, smallpox and other infectious diseases. At the beginning of the First World War the level of infectious morbidity was significantly low, but further increased and pandemic risk arose. Servicemen were mostly ill with typhus, relapsing fever, flux, cholera, smallpox and typhoid. The highest mortality rate was registered in patients with cholera, typhus and typhoid. According the prewar deployment program of the Russian Army anti-epidemiologic facilities were established. By the end of war were established 110 sanitary-and-hygienic and 90 disinfection units. However, organization of anti-epidemiologic security was unsatisfactory. Due to lack of specialists and equipment anti-epidemiologic facilities of units were under strength. Commanders of sanitary units and sanitary service had not enough resources for operational service in the Forces and facilities of rear area.

    2005-01-01

    Throughout history of European agglomerations in the nineteenth and twentieth century the relation between expanding industry and worsening sanitary and epidemiological conditions was seen. These changes, having great impact on public health, were investigated in the present study. Problems related to sanitary and epidemiological conditions in Lodz first emerged during the Russian occupation of Poland in the XIX century. The Russian Governing Council was not overseeing sanitary conditions of the city, and transferred this responsibility to the industrial bourgeoisie of Lodz. In this situation, uncontrolled development of the industry led to serious deterioration in natural environment and increase of risk for acute and chronic infectious diseases. Improvement of the sanitary situation in Lodz commenced in the period of the Second Polish Republic (1918-1939). Sanitary Divisions were created at the Lodz Department of Public Health. Activities in this Department involved, among others, detailed epidemiological examination of potable water, the investigation of manufacturing processes, retail and wholesale groceries, hygienic conditions of public housing. The activity and interventions of Sanitary Divisions contributed substantially to a decrease of incidence of various diseases and improvement of living conditions of the Lodz populations. The improvement of sanitary and epidemiological conditions in Lodz after 1918 was mainly related to the construction of water supply and sewage systems. This led to an approximation of the urban standards of this 500,000 population agglomeration to European standards.

    This interview with Julia Taft, Assistant Secretary of State for Population, Refugees and Migration concerns a wide range of well-being programs for women in the US. The ICPD Program of Action considers family planning and reproductive health in the broader contexts of women's empowerment, girls¿ and boys' education, child health, and social elements (among them economic and environmental elements), that affect the lives of girls and women. US programs and policies encompass the promotion of the whole range of well-being of women and girls, of which family planning and reproductive health are key elements. Congress has passed a law ensuring complete access to reproductive health care services by making it a crime to use force or to interfere with reproductive health providers or their patients. There was also a recent decision to require federal employees' health insurance plans to cover contraceptives. The US supports several international organizations working on population issues such as UNFPA, UNICEF, UNAIDS, WHO, and UNDP. The UN will continually have to evaluate its progress so that in 15 years human rights, civil rights, and proper health care will have been extended to the entire world.

    Accurately assessing the microbiological safety of water sources is essential to reduce waterborne fecal exposures and track progress toward global targets of safe water access. Sanitary inspections are a recommended tool to assess water safety. We collected 1,684 water samples from 902 shallow tubewells in rural Bangladesh and conducted sanitary surveys to assess whether sanitary risk scores could predict water quality, as measured by Escherichia coli. We detected E. coli in 41% of tubewells, mostly at low concentrations. Based on sanitary scores, 31% of wells were low risk, 45% medium risk, and 25% high or very high risk. Older wells had higher risk scores. Escherichia coli levels were higher in wells where the platform was cracked or broken (Δlog10 = 0.09, 0.00–0.18) or undercut by erosion (Δlog10 = 0.13, 0.01–0.24). However, the positive predictive value of these risk factors for E. coli presence was low (< 50%). Latrine presence within 10 m was not associated with water quality during the wet season but was associated with less frequent E. coli detection during the dry season (relative risk = 0.72, 0.59–0.88). Sanitary scores were not associated with E. coli presence or concentration. These findings indicate that observed characteristics of a tubewell, as measured by sanitary inspections in their current form, do not sufficiently characterize microbiological water quality, as measured by E. coli. Assessments of local groundwater and geological conditions and improved water quality indicators may reveal more clear relationships. Our findings also suggest that the dominant contamination route for shallow groundwater sources is short-circuiting at the wellhead rather than subsurface transport. PMID:28115666

    Barbosa, Ana de Oliveira; Costa, Ediná Alves

    2010-11-01

    The term sanitary safety (SS) appeared in the international debate mainly due to the emerging sanitary crisis, although its meaning has remained obscure. This paper aims to analyze the concept of SS brought into the Brazilian sanitary surveillance upon the creation of the National Health Surveillance Agency. An exploratory case study was undertaken with technical data analysis and semi-structured interviews with informants who had taken part in the process of formulating the body's institutional design. The following categories were analyzed: incorporation of the SS term into the institutional mission, the SS concept and SS mechanisms. The SS concept was analyzed in both institutional and technical discursive dimensions. The former elicits the sense of strategy, a reliable relationship and legitimacy whereas the latter shows the sense of an acceptable risk-benefit relationship from the perspective of individual and collective health protection and promotion. The SS concept was found to encompass health-related products, technologies and services, especially those designed for medical diagnosis and treatment, but environmental issues received little mention. The scope of the SS concept was shown to be widening to include the surveillance of hospital infection, drugs and blood.

  5. The health of hospitals and lessons from history: public health and sanitary reform in the Dublin hospitals, 1858-1898.

    PubMed

    Fealy, Gerard M; McNamara, Martin S; Geraghty, Ruth

    2010-12-01

    The aim was to examine, critically, 19th century hospital sanitary reform with reference to theories about infection and contagion. In the nineteenth century, measures to control epidemic diseases focused on providing clean water, removing waste and isolating infected cases. These measures were informed by the ideas of sanitary reformers like Chadwick and Nightingale, and hospitals were an important element of sanitary reform. Informed by the paradigmatic tradition of social history, the study design was a historical analysis of public health policy. Using the methods of historical research, documentary primary sources, including official reports and selected hospital archives and related secondary sources, were consulted. Emerging theories about infection were informing official bodies like the Board of Superintendence of Dublin Hospitals in their efforts to improve hospital sanitation. The Board secured important reforms in hospital sanitation, including the provision of technically efficient sanitary infrastructure. Public health measures to control epidemic infections are only as effective as the state of knowledge of infection and contagion and the infrastructure to support sanitary measures. Today, public mistrust about the safety of hospitals is reminiscent of that of 150 years ago, although the reasons are different and relate to a fear of contracting antimicrobial-resistant infections. A powerful historical lesson from this study is that resistance to new ideas can delay progress and improved sanitary standards can allay public mistrust. In reforming hospital sanitation, policies and regulations were established--including an inspection body to monitor and enforce standards--the benefits of which provide lessons that resonate today. Such practices, especially effective independent inspection, could be adapted for present-day contexts and re-instigated where they do not exist. History has much to offer contemporary policy development and practice reform and

  6. Investigations of perspective technologies, equipment and sanitary - hygienic means for Life-Support System of new generation

    NASA Astrophysics Data System (ADS)

    Shumilina, I. V.

    Creation of optimal sanitary - hygienic conditions allows to keep health and capacity of the crewmembers work at increase of space flight duration. There is a wide application experience of means, methods and equipment for sanitary - hygienic supply, which were developed and experimentally tested for space flights. However, about 800 kg personal hygiene means (napkins and towels are made with water and delivered with the Earth) are necessary for 3 crewmembers per one year. For long orbital and interplanetary flights (without an opportunity of stocks updating) it is necessary to increase a degree of Life-Support System isolation and optimization of goods turnover. Washing combined with water regeneration system is most perspective for sanitary - hygienic procedures. Therefore, creation of space equipment for washing with sanitary - hygienic water (SHW) regeneration system is especially important. The researches have shown, that to processes, which can be applied for SHW regeneration in space conditions and require insignificant quantity of additional materials (as against sorption), concern membrane methods (reverse osmosis, nanofiltration etc.). Two-step membrane unit for SHW regeneration recovered no less than 85 % of permeate with the organic and inorganic selectivity of 82-95 %. The tests of two-step membrane unit for SHW regeneration carried out on mock up solutions and real SHW, containing detergents really used in space flight conditions. The researches on a substantiation of an opportunity of clothing washing, clothing drying and the estimation of an opportunity of application of various detergents for clothing washing are urgent. The tests of water extraction technology from textile materials are carried out. Is established, that at conditional time of contact 1s, humidity of a leaving air flow from clothing drying unit comes nearer to 100 %. It is necessary to solve the problem for creation of Life-Support System of new generation for long-term space

  7. Prospective technologies and equipment for sanitary hygienic measures for life support systems

    NASA Astrophysics Data System (ADS)

    Shumilina, I. V.

    Creation of optimal sanitary hygienic conditions is a prerequisite for good health and performance of crews on extended space missions. There is a rich assortment of associated means, methods and equipment developed and experimentally tested in orbital flights. However, over a one-year period a crew of three uses up about 800 kg of ground-supplied wet wipes and towels for personal needs. The degree of closure of life support systems for long-duration orbital flights should be maximized, particularly for interplanetary missions, which exclude any possibility of re-supply. Washing with regenerated water is the ultimate sanitary hygienic goal. That is why it is so important to design devices for crew bathing during long-term space missions. Investigations showed that regeneration of wash water (WW) using membrane processes (reverse osmosis, nanofiltration etc.), unlike sorption, would not require much additional expendables. A two-stage membrane recovery unit eliminated >85% of permeate from real WW with organic and inorganic selectivity of 82 95%. The two-stage WW recovery unit was tested with artificial and real WW containing detergents available for space crews. Investigations into the ways of doing laundry and drying along with which detergents will be the best fit for space flight are also planned. Testing of a technology for water extraction from used textiles using a conventional period of contact of 1 s or more, showed that the humidity of the outgoing air flow neared 100%. Issues related to designing the next generation of space life support systems should consider the benefits of integrating new sanitary hygienic technologies, equipment, and methods.

    After recalling the numerous peace expeditions of the Italian Armed Forces in foreign countries, the author underlines the several health risk factors that such missions imply. The assessment of the biological risk should be based on the knowledge of the local sanitary situation and on the analysis of the operative characteristics of the mission: prevention is based on vaccinations (with plans based on the operative tasks and destinations) and on antimalaric chemoprophylaxis, carried out following WHO indications. In conclusion, the current organization of military field hospitals is briefly described.

    PubMed

    Biani, Natalia B; Mueller, Ulrich G; Wcislo, William T

    2009-06-01

    Cleaning symbioses represent classic models of mutualism, and some bee mites are thought to perform cleaning services for their hosts in exchange for suitable environments for reproduction and dispersal. These mutual benefits, however, have not been rigorously demonstrated. We tested the sanitary role of bee mites by correlating mite loads with fungal contamination in natural nests of Megalopta genalis and Megalopta ecuadoria and by experimentally manipulating mite loads in artificial cells with developing brood. Field observations revealed significant correlations between the presence of mites and the absence of fungi inside the brood cells, as well as between the absence of mites and increased bee mortality. Likewise, experimental brood cells with mites have fewer fungal colonies than do cells without mites. Field observations and experimental manipulations, therefore, provide clear evidence of the sanitary effect of mites in nests of Megalopta bees. This bee-mite association constitutes one of the few examples of terrestrial cleaning mutualisms.

    An estimated one fifth of all U.S. adult smokers receive health benefits through insurance plans administered by Taft-Hartley Health and Welfare Funds. Most funds do not offer comprehensive tobacco-cessation services to fund participants despite evidence that doing so would be cost effective and save lives. This paper examines the decision-making processes of Minnesota-based fund trustees and advisors to identify factors that influence decisions about modifications to benefits. Formative data about the process by which funds make health benefit modifications were collected in 2007-2008 from 25 in-depth key informant interviews with fund trustees and a cross-section of fund advisors, including administrators, attorneys, and healthcare business consultants. Analyses were performed using a general inductive approach to identify conceptual themes, employing qualitative data analysis software. The most commonly cited factors influencing trustees' decisions about health plan benefit modifications-including modifications regarding tobacco-cessation benefits-were benefit costs, participants' demand for services, and safeguarding participants' health. Barriers included information gaps, concerns about participants' response, and difficulty projecting benefit utilization and success. Advisors wielded considerable influence in decision-making processes. Trustees relied on a small pool of business, legal, and administrative advisors to provide guidance and recommendations about possible health plan benefit modifications. Providing advisors with evidence-based information and resources about benefit design, cost/return-on-investment (ROI), effectiveness, and promotion may be an effective means to influence funds to provide comprehensive tobacco-cessation benefits.

  14. The Application Of Biofilter System For Reduction Of Methane Emissions From Modern Sanitary Landfills

    NASA Astrophysics Data System (ADS)

    Sung, K.; Park, S.

    2007-12-01

    Increased atmospheric concentrations of greenhouse gases (GHG) caused by anthropogenic activities has been related to global climate change. Methane, the second most important GHG after CO2, is 21 times more effective at trapping heat than CO2. Therefore, methane emission control is of utmost importance for global warming reduction. To minimize leachate production and protect groundwater resources, modern sanitary landfills are equipped with composite covers and gas collection systems. Methane from modern sanitary landfills is vented directly to the atmosphere, except for some of the largest landfills where it is recovered as energy and burned at the site. However, the efficiency of energy recovery systems in larger landfills is reduced as the amount of CH4 generated from landfill begins to decrease. In this study, the performance of a lab-scale model biofilter system was investigated to treat CH4 gas emitted from modern sanitary landfills by conducting batch and column experiments using landfill cover soil amended with earthworm cast as the filter bed medium. From the batch experiments to measure the influence of moisture content and temperature of the filter medium on CH4 removal capacity of a biofilter system, the optimum moisture content and temperature were found to be 10-15% by weight and 25-35°C, respectively. The column experiment was conducted to measure the influence of inlet CH4 concentration and CH4 loading rate on CH4 removal capacity of a biofilter system. As the inlet CH4 concentration decreased, the percentage of CH4 oxidized increased. Up to a CH4 loading rate of 2785 g CH4 m3 h- 1 (EBRT = 7.7 min), the CH4 removal efficiency of the biofilter was able to reach 100%. Based on the results of the study, the installation of a properly managed biofilter system should be capable of achieving a reduction in atmospheric CH4 emissions from modern sanitary landfills at low CH4 generation stage.

    Major cities are congested and large sites suitable for landfill development are limited. Methane and other gases are produced at most sanitary landfills and dumps. These gases may migrate horizontally and vertically and have caused fatalities. Monitoring these gases provides data bases for design and construction of safe buildings on and adjacent to landfills. Methods of monitoring include: (1) a portable combustible gas indicator; and (2) glass flasks valved to allow simultaneous exhaust of the flask and aspiration of the sample into the flask. Samples are drawn through tubing from probes as deep as twenty-five feet below the surface.

    This study evaluated the efficiency of a shallow (0.5 m deep) waste stabilization pond series to remove high concentrations of ammonia from sanitary landfill leachate. The pond system was located at EXTRABES, Campina Grande, Paraiba, Northeast Brazil. The pond series was fed with sanitary landfill leachate transported by road tanker to the experimental site from the sanitary landfill of the City of Joao Pessoa, Paraiba. The ammoniacal-N surface loading on the first pond of the series was equivalent to 364 kg ha(-1) d(-1) and the COD surface loading equivalent to 3,690 kg ha(-1) d(-1). The maximum mean ammonia removal efficiency was 99.5% achieved by the third pond in the series which had an effluent concentration of 5.3 mg L(-1) ammoniacal-N for an accumulative HRT of 39.5 days. The removal process was mainly attributed to ammonia volatilization (stripping) from the pond surfaces as a result of high surface pH values and water temperatures of 22-26°C. Shallow pond systems would appear to be a promising technology for stripping ammonia from landfill leachate under tropical conditions.

    In most developing countries, open defecation is the 'way of life'. This practice is considered as the most serious health and environmental hazard. Prime Minister of India launched the "Swachh Bharat Mission" to accelerate the efforts for achieving universal sanitation coverage and to put focus on sanitation. To find the knowledge, attitude and practices of sanitary latrines usage in rural area, Tamil Nadu. This was a cross sectional study conducted among rural population in Kuthambakkam village, Tamil Nadu. There were a total of 1175 households in Kuthambakkam village. These households were serially numbered and of these a sample of 275 households were selected for the study using simple random sampling technique by lottery method. A structured questionnaire was used to collect information regarding the background characteristics, their knowledge, attitude and practices towards sanitary latrines usage. Descriptive statistics were calculated for background variables, the prevalence of sanitary latrines usage and open air defecation. Association between factors responsible for open air defecation was found by using chi square test. The prevalence of usage of household sanitary latrine and community latrines was 62.5% and 4.3% respectively. The prevalence of open air defecation among the study participants was 33.1%.Significant association was found between low standard of living and open air defecation practice. To solve the problem of underutilization of sanitary latrines, planning and conducting Information Education Communication activities is very essential. Effective political and administrative support is needed to scale up the sanitation program.

    2017-01-01

    The use of sanitary inspections combined with periodic water quality testing has been recommended in some cases as screening tools for fecal contamination. We conducted sanitary inspections and tested for thermotolerant coliforms (TTCs), a fecal indicator bacteria, among 7,317 unique water sources in West Bengal, India. Our results indicate that the sanitary inspection score has poor ability to identify TTC-contaminated sources. Among deep and shallow hand pumps, the area under curve (AUC) for prediction of TTC > 0 was 0.58 (95% confidence interval [CI] = 0.53–0.61) and 0.58 (95% CI = 0.54–0.62), respectively, indicating that the sanitary inspection score was only marginally better than chance in discriminating between contaminated and uncontaminated sources of this type. A slightly higher AUC value of 0.64 (95% CI=0.57–0.71) was observed when the sanitary inspection score was used for prediction of TTC > 0 among the gravity-fed piped sources. Among unprotected springs (AUC = 0.48, 95% CI = 0.38–0.55) and unprotected dug wells (AUC = 0.41, 95% CI = 0.20–0.66), the sanitary inspection score performed more poorly than chance in discriminating between sites with TTC < 1 and TTC > 0. Aggregating over all source types, the sensitivity (true positive rate) of a high/very high sanitary inspection score for TTC contamination (TTC > 1 CFU/100 mL) was 29.4% and the specificity (true negative rate) was 77.9%, resulting in substantial misclassification of the sites when using the established risk categories. These findings suggest that sanitary surveys are inappropriate screening tools for identifying TTC contamination at water points. PMID:28115676

    During the Great Patriotic War (1941-1945) there was a real danger of use by German armies of the chemical weapon against staff of Red Army. However German command didn't risked to go on conducting large-scale chemical war against the USSR that rescued from painful death millions person. A principal cause of this decision was well organized and technically provided system of antigas protection in Red Army, including precisely organized actions of sanitary-chemical protection, qualitative preparation of military doctors on these questions and presence at them effective antidotes and other means of treatment of injuries by fighting poison gases.

    In the field of rehabilitation of separate sanitary sewer systems, a large number of technical, environmental, and economic aspects are often relevant in the decision-making process, which may be modelled as a multi-objective optimization problem. Examples are those related with the operation and assessment of networks, optimization of structural, hydraulic, sanitary, and environmental performance, rehabilitation programmes, and execution works. In particular, the cost of investment, operation and maintenance needed to reduce or eliminate Infiltration from the underground water table and Inflows of storm water surface runoff (I/I) using rehabilitation techniques or related methods can be significantly lower than the cost of transporting and treating these flows throughout the lifespan of the systems or period studied. This paper presents a comprehensive I/I cost-benefit approach for rehabilitation that explicitly considers all elements of the systems and shows how the approximation is incorporated as an objective function in a general evolutionary multi-objective optimization model. It takes into account network performance and wastewater treatment costs, average values of several input variables, and rates that can reflect the adoption of different predictable or limiting scenarios. The approach can be used as a practical and fast tool to support decision-making in sewer network rehabilitation in any phase of a project. The fundamental aspects, modelling, implementation details and preliminary results of a two-objective optimization rehabilitation model using a genetic algorithm, with a second objective function related to the structural condition of the network and the service failure risk, are presented. The basic approach is applied to three real world cases studies of sanitary sewerage systems in Coimbra and the results show the simplicity, suitability, effectiveness, and usefulness of the approximation implemented and of the objective function proposed

    Deaths by venomous animals are medical emergencies that can lead to death and thus constitute sanitary problems in some regions of the world. In the South of America, the accidents by these animals are a common sanitary problem especially in warm, tropical or subtropical regions, related with rural work in several countries. Argentina is located in the extreme South of South America and a minor part of the continental surface is in tropical or subtropical regions, where most of the accidents by venomous animals happen. However, in the big cities in the center and South of the country, with no relation to rural work, scorpionism, mostly due to the synanthropic and facultative parthenogenetic scorpion Tityus trivittatus, has become a sanitary problem in the last few decades. This scorpion is present in the biggest cities of Argentina and in the last decades has killed over 20 children in provinces of the center and north of the country, mostly in big cities. In addition, it seems that this species is growing and spreading in new regions of the cities. In this revision, some characteristics of this scorpion regarding its habitat, spreading in Buenos Aires city, combat measures and available treatments are discussed. PMID:24759176

    Due to the 1997 summer flood, the Pomeranian and Gdańsk Bays were polluted with a significant amount of bacteriologically contaminated Oder and Vistula rivers waters. The purpose of this study was to determine the sanitary state of both bays during the flood and directly after it, the range of direction of distribution of the bacteriological contamination brought in by Vistula and Oder waters. On the basis of examination results, the sanitary state of the bays waters was found to be worse, particularly with regard to indicators: total bacterial number (at 20 °C and 37 °C) and Most Probable Number (MPN) of coliform and faecal coliform bacteria. Bacteria of the Pseudomonas group (Pseudomonas aeruginosa, Pseudomonas fluorescens), Enterobacteriaceae group (m.in. Proteus vulgaris), as well as enterococci (Streptoccus) and staphylococci (Staphylococcus) were found in water samples from Pomeranian and Gdańsk Bays. In the Pomeranian Bay the waters spread to the west (due to weather conditions), whereas in Gdańsk Bay they remained mainly in the coastal zone and then moved to the east. An improvement in the sanitary state of both bay waters was observed at the end of August.

    The aim of the present study is to evaluate whether workers in the sanitary fixtures industry are a category at risk of developing cardiovascular diseases, and in particular, whether chronic noise exposure may play a role in cardiovascular effects in exposed workers. Seventy-five employees engaged in sanitation fixtures production and a control group of sixty-four office workers, who were not exposed to agents that could damage the cardiovascular system, participated in our study. The selected workers completed a clinical-anamnestic questionnaire, and underwent a medical examination, blood pressure test, electrocardiogram (ECG), blood tests, and audiometry. Measurements of environmental noise, dust, and lead were also carried out. The exposed workers, in comparison to the control group, showed a higher frequency of hypertension, systolic and diastolic blood pressure (p<0.05, p<0.05), as well as electrocardiographic abnormalities (p<0.05). There was also a higher frequency of hypertension and electrocardiographic abnormalities among subjects with audiometric deficit compared to normoacoustic subjects (p<0.05 and p<0.05). from our study suggest that work activity in the sanitary fixtures industry can have an influence on the cardiovascular system, and noise can be the main cause of damage for the cardiovascular system in exposed workers, as cardiovascular damage seems to be linked to hearing loss.

    Silicosis remains the most prevalent occupational disease worldwide. There have been no specific studies focusing on the association between exposure settings at work and the clinical severity in silicosis patients. In this study, we describe and compare the clinical characteristics and silicosis-associated exposure history at work among workers from several types of ceramic production facilities in Taiwan. We reviewed the medical records of 221 patients who were first diagnosed with silicosis at the Occupational Medicine Clinic of Northern Taiwan in 2012. For each patient, we collected data on demographic characteristics, smoking habits, working history, duration of exposure, and years on the first relevant job. We also retrieved clinical reports of the pulmonary function test and the baseline chest radiography used for silicosis staging. As compared to other ceramic workers, sanitary ceramic workers had a worse X-ray type (p=0.044), more advanced age (p<0.001), longer working duration (p=0.029), and a higher proportion of starting the first relevant job prior to the year 1975 (p=0.003). However, after adjusting for age, work duration, and an initial occupational exposure prior to 1975, sanitary ceramic workers showed a comparable risk for worse X-ray findings to other ceramic workers (adjusted odds ratio=1.18, p=0.704). Results of multivariable regression models on individual lung function parameter also suggested comparably impaired lung function tests between sanitary and other ceramic workers (p>0.05). In this study, we found that sanitary ceramic workers were at a similar risk to other ceramic workers for moderate to severe silicosis when older age and longer working duration were accounted for.

    The sanitary surveillance (Visa) performs several practices, on different objects and its actions are guided by principles and guidelines of the SUS. It was done a critical reflection on the interaction conditions of practice in Visa, with a constitutional proposition of the SUS: integral care. The analysis was based on the theory of structuration (Giddens) that considers mobilization of structural resources as dimensions of social interaction, which would justify the legitimacy exercised since the standards. Have been analyzed the following categories: Visa and its insertion within the SUS; the integral care and the Visa; and political impediments. The Visa has been organized by National Health Surveillance Agency. Nowadays it has as sanitary responsibilities, communication with society and health promotion. The proposal of the literature concerning integral care is based on the assistance issue. The organization of the services in the different federative entities is the sense of integral care most adopted by Visa. Political impediments focus on the institutional renewal, on the conflicts of interest arena, on the distance between formulated policies and established practices and gaps concerning work management and the insufficiency of financial support.

    Lack of basic infrastructure, poor knowledge of hygiene and practices in food service establishments can contribute to outbreaks of foodborne illnesses. The aims of this study were to investigate the food safety knowledge and practices of food handlers and to assess the sanitary conditions of food service establishments in Bahir Dar town. A cross-sectional study was conducted in Bahir Dar in May 2011 and data were collected using questionnaire and observation checklist on employees' knowledge of food hygiene and their practices as well on sanitary conditions of the food service establishments The median age of the food handlers was 22 years and among the 455 subjects 99 (21.8%) have had food hygiene training. Sixty six percent of the establishments had flush toilets whereas 5.9% of the establishment had no toilet. Only 149 (33.6%) of the establishments had a proper solid waste collection receptacle and there was statistically significant association between the sanitary conditions and license status of the establishments (p=0.01). Most of all, knowledge gap in food hygiene and handling practice was observed. In addition, there was statistically significant difference between trained (professional) handlers and non-trained handlers with regard to food hygiene practices (p<0.05). While more than 50% of the handlers prepare meals ahead of the peak selling time, more than 50% of the left over was poorly managed. This study revealed poor sanitary conditions and poor food hygiene practices of handlers. Educational programs targeted at improving the attitude of food handlers and licensing and regular inspections have been recommended.

    Poor menstrual knowledge and access to sanitary products have been proposed as barriers to menstrual health and school attendance. In response, interventions targeting these needs have seen increasing implementation in public and private sectors. However, there has been limited assessment of their effectiveness. Assess the impact of providing reusable sanitary pads and puberty education on girls' school attendance and psychosocial wellbeing outcomes. A cluster quasi-randomised controlled trial was conducted across 8 schools, including 1124 girls, in rural Uganda. Schools were allocated to one of four conditions: the provision of puberty education alone; reusable sanitary pads alone; puberty education and reusable sanitary pads; and a control (no intervention). The primary outcome was school attendance. Secondary outcomes reflected psychosocial wellbeing. At follow-up, school attendance had worsened for girls across all conditions. Per-protocol analysis revealed that this decline was significantly greater for those in the control condition d = 0.52 (95%CI 0.26-0.77), with those in control schools having a 17.1% (95%CI: 8.7-25.5) greater drop in attendance than those in any intervention school. There were no differences between the intervention conditions. High rates of school drop-out and transfer meant the trial suffered from substantial participant drop-out. Intention-to-treat analyses using two different imputation strategies were consistent with the main results, with mean differences of 5.2% attendance in best-case and 24.5% in worst-case imputations. Results were robust to adjustments for clustering. There was no impact of the interventions on girls' self-reported shame or insecurity during menstruation. Results of the trial support the hypothesised positive impact of providing sanitary pads or puberty education for girls' school attendance in a developing country context. Findings must be interpreted with caution in light of poor participant retention

    Municipal sanitary landfills generate leachate that New York State regulations require to be collected and treated to avoid contaminating surface water and groundwater. One option for treating leachate is to haul it to municipal wastewater treatment facility. This option may be expensive, may require excessive energy for transportation, and may require pretreatment to protect the receiving facility`s processes. An alternative is on-site treatment and discharge. Personnel from the Town of Fenton, New York; Hawk Engineering, P.C.; Cornell University; and Ithaca College designed, built, and operated a pilot constructed wetland for treating leachate at the Town of Fenton`s municipal landfill. Themore » system, consisting of two overland flow beds and two subsurface flow beds has been effective for 18 months in reducing levels of ammonia (averaging 85% removal by volatilization and denitrification) and total iron (averaging 95% removal by precipitation and sedimentation), two key constituents of the Fenton landfill`s leachate. The system effects these reductions with zero chemical and energy inputs and minimal maintenance. A third key constituent of the leachate, manganese, apparently passes through the beds with minimal removal. Details and wetland considerations are described.« less

    Trachoma is a major cause of avoidable blindness. It is responsible for about six million blind people worldwide, mostly in the poor communities of developing countries. One of the major strategies advocated for the control of the disease is the application of various environmental sanitary measures to such communities. To assess the evidence for the effectiveness of environmental sanitary measures on the prevalence of active trachoma in endemic areas. We searched the Cochrane Central Register of Controlled Trials - CENTRAL in The Cochrane Library (Issue 2, 2007), MEDLINE (1966 to July 2007), EMBASE (1980 to July 2007), LILACS (July 2007), reference list of trials and the Science Citation Index. We also contacted agencies, experts and researchers in trachoma control. We included randomised and quasi-randomised controlled trials comparing any form of environmental hygiene measures with no measure. These hygiene measures included fly control, provision of water and health education. Participants in the trials were people normally resident in the trachoma endemic areas. Two authors independently extracted data and assessed the quality of trials. Study authors were contacted for additional information. Four trials met the inclusion criteria but meta-analysis was not conducted due to heterogeneity of the studies. Two studies that assessed insecticide spray as a fly control measure found that trachoma is reduced by at least 55% to 61% with this measure compared to no intervention. However, another study did not find insecticide spray to be effective in reducing trachoma. One study found that another fly control measure, latrine provision, reduced trachoma by 29.5% compared to no intervention; this was, however, not statistically significantly different. Another study revealed that health education on personal and household hygiene reduced the incidence of trachoma such that the odds of reducing trachoma in the health education village was about twice that of the no

    Monitoring of environment in regions of the location of waste landfills includes the implementation of the control over a sanitary condition of soils. The main origins of the spread ofpollutants into soils are the solid particles from aerosol emissions from the functioning of landfills transmitted to surrounding territories. Within zones of the impact of three largest waste landfills in the Saratov region (Aleksandrovsky, Guselsky in the city of Saratov and Balakovsky in the city of Balakovo) there were taken 152 soil samples. According to results of the estimation in soil concentration of gross and motile forms of heavy metals of the first (Zn, Cd, Ni) and the second danger classes (Cu, Cr, Pb) there was performed the analysis of coefficients of danger- K0 and total coefficients ofpollution - Zc. There was executed the assessment of both a sanitary and hygienic condition of soils and degree of danger ofpollution. The most contrast areal features of the distribution of the danger coefficient - Ko in soils are characteristic for motile forms of heavy metals. For all three studied objects persistently there is stood out the dangerous and areal pollution of soils by association of Ni and Cu . The danger ofpollution of soils by gross forms of heavy metals is minimum. The coefficient of total pollution of Zc exceeds admissible level on motile forms of heavy metals only for the soils surrounding the Balakovo landfill. In zones of the impact of waste landfills there are located the processed lands with an adverse sanitary and hygienic condition of soils. In the region of the Guselsky object soils of the processed agricultural grounds are dangerously polluted by motile forms of Ni and Cu. In vicinities of the Balakovo waste landfill considerable areas of private gardening enterprises are dangerously polluted by the motile forms of Ni, Cu and Zn.

    Parabens (alkyl esters of p-hydroxybenzoic acid) are widely used as antimicrobial preservatives in personal care products, pharmaceuticals, and foodstuffs. Although parabens have been reported to be used as antimicrobials in certain types of papers (e.g., wet sanitary or hygiene wipes), little is known about the occurrence of these compounds in paper products. In this study, we determined the concentrations of six paraben analogs, methyl (MeP), ethyl (EtP), propyl (PrP), butyl (BuP), benzyl (BzP), and heptyl parabens (HepP), in 253 paper products divided into 18 categories, using liquid chromatography-tandem mass spectrometry (LC-MS/MS). At least one of the six parabens was detected in almost all (detection rate: 98%) paper samples, and the total concentrations (∑PBs; sum of six parabens) ranged from 1.85 to 3,220,000 ng/g (geometric mean (GM): 103; median: 55.1 ng/g). Sanitary wipes contained very high concentrations of ∑PBs (GM: 8300 ng/g). Paper currencies, tickets, business cards, food cartons, flyers, and newspapers contained notable concentrations of ∑PBs, and the GM concentrations in these paper categories were on the order of a few tens to thousands of nanograms per gram. One source of parabens in paper products is the use of these chemicals as antifungal agents. MeP and PrP were the predominant analogs, accounting for approximately 62% and 16% of the total concentrations of parabens, respectively. On the basis of measured concentrations and frequency of handling of paper products, we estimated the daily intake (EDI) of parabens through dermal absorption. The GM and 95th percentile EDI values were 6.31 and 2050 ng/day, respectively, for the general population. Among the paper categories analyzed, sanitary wipes contributed to the majority (>90%) of the exposures. Copyright © 2013 Elsevier B.V. All rights reserved.

  6. Sanitary protection zoning based on time-dependent vulnerability assessment model - case examples at two different type of aquifers

    Delineation of sanitary protection zones of groundwater source is a comprehensive and multidisciplinary task. Uniform methodology for protection zoning for various type of aquifers is not established. Currently applied methods mostly rely on horizontal groundwater travel time toward the tapping structure. On the other hand, groundwater vulnerability assessment methods evaluate the protective function of unsaturated zone as an important part of groundwater source protection. In some particular cases surface flow might also be important, because of rapid transfer of contaminants toward the zones with intense infiltration. For delineation of sanitary protection zones three major components should be analysed: vertical travel time through unsaturated zone, horizontal travel time through saturated zone and surface water travel time toward intense infiltration zones. Integrating the aforementioned components into one time-dependent model represents a basis of presented method for delineation of groundwater source protection zones in rocks and sediments of different porosity. The proposed model comprises of travel time components of surface water, as well as groundwater (horizontal and vertical component). The results obtained using the model, represent the groundwater vulnerability as the sum of the surface and groundwater travel time and corresponds to the travel time of potential contaminants from the ground surface to the tapping structure. This vulnerability assessment approach do not consider contaminant properties (intrinsic vulnerability) although it can be easily improved for evaluating the specific groundwater vulnerability. This concept of the sanitary protection zones was applied at two different type of aquifers: karstic aquifer of catchment area of Blederija springs and "Beli Timok" source of intergranular shallow aquifer. The first one represents a typical karst hydrogeological system with part of the catchment with allogenic recharge, and the second one

    Conventional sanitary landfill leachate treatment has recently been complemented and, in some cases, completely replaced by reverse osmosis technology. Despite the good quality of treated water, the efficiency of the process is low and a large volume of reverse osmosis concentrate has to be either discharged or further treated. In this study, the use of anodic oxidation combined with electro-Fenton processes to treat the concentrate obtained in the reverse osmosis of sanitary landfill leachate was evaluated. The anodic oxidation pretreatment was performed in a pilot plant using an electrochemical cell with boron-doped diamond electrodes. In the electro-Fenton experiments, a boron-doped diamond anode and carbon-felt cathode were used, and the influence of the initial pH and iron concentration were studied. For the experimental conditions, the electro-Fenton assays performed at an initial pH of 3 had higher organic load removal levels, whereas the best nitrogen removal was attained when the electrochemical process was performed at the natural pH of 8.8. The increase in the iron concentration had an adverse impact on treatment under natural pH conditions, but it enhanced the nitrogen removal in the electro-Fenton assays performed at an initial pH of 3. The combined anodic oxidation and electro-Fenton process is useful for treating the reverse osmosis concentrate because it is effective at removing the organic load and nitrogen-containing species. Additionally, this process potentiates the increase in the biodegradability index of the treated effluent. Copyright © 2016 Elsevier Ltd. All rights reserved.

    2010-11-01

    This study analyses law bills towards the sanitary control of alcohol advertisement in the mass media presented to the Brazilian Congress from 1988 to 2004. The sanitary control of this advertising is a controversial issue bringing about an ethical-political debate in which the health-protecting interests conflict with commercial ones even after scientific evidence has established increasing alcohol intake as a health and social issue worldwide. The content analysis of 67 of such law bills was carried out, and these proposals were shown to consist mostly of strategies to both cope with alcohol advertising by dissociating from the product those values that might interfere with the children and teenagers' building of their social identity and limit advertisement contents in the mass media given the higher vulnerability of the subjects in that age range. This study reveals complexes challenges for the control of alcohol advertisement that in turn lead to rethinking the action of the State apparatus in dealing with this major public health issue.

    In the Russian Federation anthrax epizootics are still being registered among animals as well as epidemic foci of the population. This situation is linked to natural reservoirs of the pathogen - numerous anthrax burial sites which belong to class I of dangerous objects. In this connection, a one-kilometer sanitary protective zone is required according to current Russian Federation legislation. As a result, a significant land of the country is unsuitable for any agricultural use. Meanwhile, epizootologo-epidemiological observations indicate to that different anthrax burial sites differ in their characteristics and represent varying degrees of the risk. In connection with the development of the agricultural sector, intensive construction and the development of new and abandoned areas there is a need of creating unified approaches to assess the risk of anthrax burial sites, as well as to determine the size of sanitary protection zones based on the risk assessment. This article represents an original methodology to assess the actual danger of anthrax burial sites. It is based on a comprehensive multi-factor quantity-related risk assessment, described by a model that accounting the importance of each study for natural, social and biological factors. Undertaking this methodology allowed to reveal a degree of danger of anthrax burial sites located in different territories of the Russian Federation, and helped to substantiate the dimensions of their sanitary protection zones.

    Sanitary and hygienic state of the Baltic navy ships in the 18th century was considered as unsatisfactory due to inappropriate habitation conditions answering hygienic requirements. The reason for the low ship habitation of that time was limited technological possibilities of the sail shipbuilding, lack of appropriate labour, and life and rest conditions for navy servicemen. In fact, wooden ships were not suitable for life activity of the navy crew, but contributed to disease increase. Because of the rapid development of the' navy hygiene and improvement of shipbuilding technologies, sanitary and hygienic state of local navy ships had became improving. With a glance on recommendations, developed by physicians D.P.Sinopeus and A.G.Bakherakht, were made following improvements: were implemented ventilators on ships, daily fumigation of ships rooms, monitoring of personal hygiene.

    Tritium content in the leachate of sanitary landfills, in concentrations well above those observed in global precipitation, can be used as a tracer for the evaluation of the contamination of groundwater in piezometers of the landfills and in neighbouring tubular wells. This possibility was first investigated in Brazil for sanitary landfills in the region of Belo Horizonte City. Tritium levels together with the content of metals present in water and the measurement of soil electrical conductivity, proved to be valuable for these studies and also as a tracer for hydrodynamic studies of the surface water in the Ressaca creek.

    This paper reviews the most common health hazards occurring among personnel of peacekeeping and stabilization missions functioning within armed conflicts in the contemporary world. Military operations have been executed in diverse climatic and sanitary conditions, which are frequently unfamiliar for their participants. Some of them, e.g. the UN peacekeeping missions in the Middle East (Lebanon, the Golan Heights), have been carried out in a relatively stable geopolitical environment; whereas, stabilization missions in Iraq and Afghanistan, which are actually combat activities, undoubtedly fall into the group of the most perilous military operations in the world. Hot or cold climate, poor sanitary and hygienic conditions along with warfare facilitate the occurrence of numerous diseases and body injuries not only among the local people but also among peacekeepers, who represent the population of immigrants. Health hazards which pose major epidemiological threats in combat zones are arthropod-borne, food and water-borne, respiratory tract diseases, sexually transmitted diseases, enzootic diseases, battle injuries, and non- -battle injuries, e.g. traffic accidents. Another considerable health problem are psychiatric disorders, which can either appear directly after the occurrence of a traumatic event in a combat zone or indirectly, after some time had elapsed. In addition to the health hazards listed above, environmental factors such as changeable weather conditions and local fauna may also be life threatening.

  8. Isolation of heavy metal influx to the Cookeville sanitary sewer system and impact on municipal sludge management

    DOE Office of Scientific and Technical Information (OSTI.GOV)

    George, D.B.; Borup, M.B.; Adams, V.D.

    The city of Cookeville, Tennessee, has been experiencing problems with municipal sludge management. Of particular concern was the high concentration of regulated trace metals in the sludge. Primarily, cadmium limited the amount of sludge which was spread on the available cropland in 1985. The purpose of this project was to determine the major sources of heavy metal influx to the city's sanitary sewer system and the potential effects of heavy metals on sludge management. In general, the findings of the study indicate that city enforcement of existing State of Tennessee and city industrial pretreatment requirements will most likely extend themore » useful life of the currently available 388 ha land application sites to as much as ten years for certain sites. Cadmium governed the annual sludge application rates to the agricultural land. One plating industry discharged over 90% of the cadmium, copper, nickel, and zinc mass to the sanitary sewer. In addition, during 1986, the average concentration of most of the trace metals monitored in the municipal sludge deceased from levels reported in 1985.« less

    Müller, Gabriel Timm; Giacobbo, Alexandre; Santos Chiaramonte, Edson Abel dos

    Highlights: • Photoelectrooxidation (PEO) emerges as a new technology for leachate treatment. • Aging of sanitary landfills acts on leachate composition and biodegradability. • PEO is applied as leachate pretreatment before the biological processes. • PEO produced significant changes in the leachate matrix, easing biological process. - Abstract: The sanitary landfill leachate is a dark liquid, of highly variable composition, with recalcitrant features that hamper conventional biological treatment. The physical–chemical characteristics of the leachate along the landfill aging, as well as their effects on the efficiency of the conventional treatment, were evaluated at this paper. The feasibility of photoelectrooxidation processmore » as an alternative technique for treatment of landfill leachates was also determined. Photoelectrooxidation experiments were conducted in a bench-scale reactor. Analysis of the raw leachate revealed many critical parameters demonstrating that the recalcitrance of leachate tends to increase with time, directly influencing the decline in efficiency of the conventional treatment currently employed. The effects of current density and lamp power were investigated. Using a 400 W power lamp and a current density of 31.5 mA cm{sup −2}, 53% and 61% efficiency for the removal of ammoniacal nitrogen and chemical oxygen demand were respectively achieved by applying photoelectrooxidation process. With the removal of these pollutants, downstream biological treatment should be improved. These results demonstrate that photoelectrooxidation is a feasible technique for the treatment of sanitary landfill leachate, even considering this effluent’s high resistance to treatment.« less

    2013-01-01

    Through the history of railways, wooden crossties impregnated with potentially hazardous creosote tar, have been used for years. There are six major classes of compounds in the creosote: aromatic hydrocarbons; tar acids/phenolics; tar bases/nitrogen-containing heterocycles; aromatic amines; sulfur-containing heterocycles; and oxygen-containing heterocycles. The creosote molecules applied in railway crossties can be released in the environment and they can bioaccumulate in animals and vegetables. Some constituents (benzo(a)pyrene and phenolics like benzene) are considered as being carcinogenic which renders the entire complex of creosote to be classified as potentially carcinogenic. After several decades of use the railway-ties are been recycled for varies uses like fences, stakes for agriculture and fruit production or bank protection. In this paper are examined some environmental and sanitary risks from wood impregnated with creosote reported in the literature.

    1988-12-01

    A sanitary and technological diagnosis of the goat cheese rural process was carried out. The purpose was to obtain more information for the planning of a program aimed to the improvement of this small agroindustry. Samples of milk, curdle, dry abomasum, rennet, water and cheese of 10% of the small industries of two rural villages in two agricultural seasons, were taken. Moreover, dilutions of the utensils and goat udders were prepared. The samples were subjected to microbiological analysis of mesophilic aerobic bacteria count, most probable number of total and fecal coliforms, and detection of Staphylococcus aureus coagulase (+), Salmonella typhi and Brucella melitensis. Proximate chemical analysis and determinations of sodium chloride and titratible acidity in milk, cheese, dry abomasum and rennet, were carried out. Goat milk was also subjected to analysis of density. It was found that significant sanitary failures are present during th whole goat cheese process, although the highest bacteria contamination occurred at the milking, curdling and filling stages. These are characterized by excessive handling and absolute lack of hygiene. The pathogen B. melitensis was absent; therefore the causes of poisoning were attributed to the toxin produced by S. aureus and to the significant count of fecal coliforms found in the goat cheese. Even though the goats are fed under a poor feeding system, the milk presented a normal physical and chemical composition. Nevertheless, protein and fat matter losses occur during cheese preparation, as a result of handling practices and lack of process control.

  4. Estimating the Prevalence of Potential Enteropathogenic Escherichia coli and Intimin Gene Diversity in a Human Community by Monitoring Sanitary Sewage

    Yang, Kun; Pagaling, Eulyn

    2014-01-01

    Presently, the understanding of bacterial enteric diseases in the community and their virulence factors relies almost exclusively on clinical disease reporting and examination of clinical pathogen isolates. This study aimed to investigate the feasibility of an alternative approach that monitors potential enteropathogenic Escherichia coli (EPEC) and enterohemorrhagic E. coli (EHEC) prevalence and intimin gene (eae) diversity in a community by directly quantifying and characterizing target virulence genes in the sanitary sewage. The quantitative PCR (qPCR) quantification of the eae, stx1, and stx2 genes in sanitary sewage samples collected over a 13-month period detected eae in all 13 monthly sewage samples at significantly higher abundance (93 to 7,240 calibrator cell equivalents [CCE]/100 ml) than stx1 and stx2, which were detected sporadically. The prevalence level of potential EPEC in the sanitary sewage was estimated by calculating the ratio of eae to uidA, which averaged 1.0% (σ = 0.4%) over the 13-month period. Cloning and sequencing of the eae gene directly from the sewage samples covered the majority of the eae diversity in the sewage and detected 17 unique eae alleles belonging to 14 subtypes. Among them, eae-β2 was identified to be the most prevalent subtype in the sewage, with the highest detection frequency in the clone libraries (41.2%) and within the different sampling months (85.7%). Additionally, sewage and environmental E. coli isolates were also obtained and used to determine the detection frequencies of the virulence genes as well as eae genetic diversity for comparison.

    The restructuring of the State Sanitary Inspectorate was determined by the need to adjust the existing system to the new structure- and task-oriented standards introduced by the administrative reforms at the provincial level. This brought about a lot of changes in the way State County Sanitary Inspectors operate. For first few months after the enforcement of the Act of January 23.2009 amending certain acts regarding reorganization and redistribution of competences of the public administration at the provincial level (Journal of Laws, No. 92, item. 753, 2009) brought about a lot of ambiguities and expectations. Such unresolved issues are typical for the initial or transition period after implementation of a new law. The approach to the operation of the State Sanitary Inspectorate at the county level depicted in the article lays the emphasis on the challenges in the legal and task-oriented domain that arose after coming into force of the aforementioned amendment. By way of conclusion, the authors of the article briefly summaries the practical outcomes of the transformations undergone by the State Sanitary Inspectorate at the county level.

    Recognizing how human behaviors affect the milk process can be useful to understand variations in hygienic and sanitary parameters in bulk tank milk. Furthermore, this knowledge could be used to design management programs that guarantee milk quality, favoring the optimization of such processes. Forty-six milkers from the same number of dairy farms in Antioquia province (Colombia) were interviewed to establish the main factors associated to milk quality. Technical knowledge, motivations, and behavior of the personnel and its effect on hygienic and sanitary quality of milk were evaluated. Quality was assessed in terms of colony-forming units (CFU) and somatic cell count (SCC) in bulk tank milk. Two factors from a multivariate mixed data analysis were evaluated. One of those factors explained 9.51% of the total variability, related with in-farm availability and use of tools and the relationships between milker and manager. The other factor, associated with work environment and recognition, explained 6.97% of the total variability. The variables that best explained CFU levels were Knowledge of the udder condition at milking, and Milking type (parlor or pasture). The SCC was associated to knowledge of animal handling, schooling of milkers, milking site, and the groups derived from the cluster analysis by farm. In conclusion, milker attitudes and behaviors can affect CFU and SCC in bulk tank milk. PMID:28926583

    Trachoma is a major cause of avoidable blindness. It is responsible for about six million blind people worldwide, mostly in the poor communities of developing countries. One of the major strategies advocated for the control of the disease is the application of various environmental sanitary measures to such communities. To assess the evidence for the effectiveness of environmental sanitary measures on the prevalence of active trachoma in endemic areas. We searched CENTRAL (which contains the Cochrane Eyes and Vision Group Trials Register) (The Cochrane Library 2011, Issue 9), MEDLINE (January 1950 to September 2011), EMBASE (January 1980 to September 2011), Latin American and Caribbean Literature on Health Sciences (LILACS) (January 1982 to September 2011), the metaRegister of Controlled Trials (mRCT) (www.controlled-trials.com) and ClinicalTrials.gov (www.clinicaltrials.gov). There were no date or language restrictions in the electronic searches for trials. The electronic databases were last searched on 23 September 2011. We checked the reference list of included trials and the Science Citation Index. We also contacted agencies, experts and researchers in trachoma control. We included randomised and quasi-randomised controlled trials comparing any form of environmental hygiene measures with no measure. These hygiene measures included fly control, provision of water and health education. Participants in the trials were people normally resident in the trachoma endemic areas. Two authors independently extracted data and assessed the quality of the included trials. Study authors were contacted for additional information. Six trials met the inclusion criteria but we did not conduct meta-analysis due to heterogeneity of the studies. We included six studies with a total of 12,294 participants from 79 communities. Two studies that assessed insecticide spray as a fly control measure found that trachoma is reduced by at least 55% to 61% with this measure compared to no

    Solid waste disposal were studied in Volusia County to protect the water supply in the area. Highlands in this County are of limited areal extent and, most significantly, the sand hills and ridges are in areas where recharge of the Floridan aquifer occurs. This study proves that well drained soils meeting the current State requirements are of limited areal extent. These areas should not be utilized as sanitary landfill sites! Rather, it is recommended that the Tomoka Farm Road site into the adjacent wetlands be extended. The County site on Rima Ridge recommended by Greenleaf-Telesca as the primary waste burial site in the County should be re-evaluated because of potential danger to the Daytona Beach water supply.

    Increased education of girls in developing contexts is associated with a number of important positive health, social, and economic outcomes for a community. The event of menarche tends to coincide with girls' transitions from primary to secondary education and may constitute a barrier for continued school attendance and performance. Following the MRC Framework for Complex Interventions, a pilot controlled study was conducted in Ghana to assess the role of sanitary pads in girls' education. A sample of 120 schoolgirls between the ages of 12 and 18 from four villages in Ghana participated in a non-randomized trial of sanitary pad provision with education. The trial had three levels of treatment: provision of pads with puberty education; puberty education alone; or control (no pads or education). The primary outcome was school attendance. After 3 months, providing pads with education significantly improved attendance among participants, (lambda 0.824, F = 3.760, p<.001). After 5 months, puberty education alone improved attendance to a similar level (M = 91.26, SD = 7.82) as sites where pads were provided with puberty education (Rural M = 89.74, SD = 9.34; Periurban M = 90.54, SD = 17.37), all of which were higher than control (M = 84.48, SD = 12.39). The total improvement through pads with education intervention after 5 months was a 9% increase in attendance.

    During the second half of the eighteenth century the Dutch East India Company got more and more worried about the worsening sanitary situation aboard its vessels, at the Cape of Good Hope and in Batavia. Several plans were submitted to the directors of the company, aiming at the improvement of this situation. In 1768, J.C.M. Radermacher, a member of the Council of India, proposed the construction of a new hospital at the Cape of Good Hope (based on the building plan of the Hôtel-Dieu in Paris, as well as the improvement of the European hospitals in Batavia, the Buiten-Hospitaal. Nevertheless, the sanitary situation soon worsened again, as a consequence of the impoverishment of the Company.

    An improved understanding of sources and timing of water and nutrient fluxes associated with urban stream restoration is critical for guiding effective watershed management. We investigated how sources, fluxes, and flowpaths of water, carbon (C), nitrogen (N), and phosphorus (P) shift in response to differences in stream restoration and sanitary infrastructure. We compared a restored stream with 3 unrestored streams draining urban development and stormwater management over a 3 year period. We found that there was significantly decreased peak discharge in response to precipitation events following stream restoration. Similarly, we found that the restored stream showed significantly lower monthly peak runoff (9.4 ± 1.0 mm d-1) compared with two urban unrestored streams (ranging from 44.9 ± 4.5 to 55.4 ± 5.8 mm d-1) draining higher impervious surface cover. Peak runoff in the restored stream was more similar to a less developed stream draining extensive stormwater management (13.2 ± 1.9 mm d-1). Interestingly, the restored stream exported most carbon, nitrogen, and phosphorus loads at relatively lower streamflow than the 2 more urban streams, which exported most of their loads at higher and less frequent streamflow. Annual exports of total carbon (6.6 ± 0.5 kg ha-1 yr-1), total nitrogen (4.5 ± 0.3 kg ha-1 yr-1), and total phosphorus (161 ± 15 g ha-1 yr-1) were significantly lower in the restored stream compared to both urban unrestored streams (p < 0.05) and similar to the stream draining stormwater management. Although stream restoration appeared to potentially influence hydrology to some degree, nitrate isotope data suggested that 55 ± 1 % of the nitrate in the restored stream was derived from leaky sanitary sewers (during baseflow), similar to the unrestored streams. Longitudinal synoptic surveys of water and nitrate isotopes along all 4 watersheds suggested the importance of urban groundwater contamination from leaky piped infrastructure. Urban groundwater

    In this research, quasi-spherical-shaped zinc oxide nanoparticles (ZnO NPs) were synthesized by a simple cost-competitive aqueous precipitation method. The engineered NPs were characterized using several validation methodologies: UV–Vis spectroscopy, diffuse reflection UV–Vis, spectrofluorometry, transmission electron microscopy (TEM), nanoparticle tracking analysis (NTA), and Fourier transform infrared (FTIR) spectroscopy with attenuated total reflection (ATR). A procedure was established to coat a landrace of red maize using gelatinized maize starch. Each maize seed was treated with 0.16 mg ZnO NPs (~7.7 × 109 particles). The standard germination (SG) and accelerated aging (AA) tests indicated that ZnO NP-treated maize seeds presented better physiological quality (higher percentage of normal seedlings) and sanitary quality (lower percentage of seeds contaminated by microorganisms) as compared to controls. The application of ZnO NPs also improved seedling vigor, correlated to shoot length, shoot diameter, root length, and number of secondary roots. Furthermore, shoots and roots of the ZnO NP-treated maize seeds showed a marked increment in the main active FTIR band areas, most notably for the vibrations associated with peptide-protein, lipid, lignin, polysaccharide, hemicellulose, cellulose, and carbohydrate. From these results, it is concluded that ZnO NPs have potential for applications in peasant agriculture to improve the quality of small-scale farmers’ seeds and, as a result, preserve germplasm resources.

    The management of menstruation has come to the fore as a barrier to girls' education attainment in low income contexts. Interventions have been proposed and piloted, but the emerging nature of the field means limited evidence is available to understand their pathways of effect. This study describes and compares schoolgirls' experiences of menstruation in rural Uganda at the conclusion of a controlled trial of puberty education and sanitary pad provision to elucidate pathways of effect in the interventions. Semi-structured interviews were undertaken with schoolgirls who participated in the Menstruation and the Cycle of Poverty trial concurrent with the final set of quantitative surveys. A framework approach and cross-case analysis were employed to describe and compare the experiences of 27 menstruating girls across the four intervention conditions; education (n = 8), reusable sanitary pads (n = 8), education with reusable sanitary pads (n = 6), and control (n = 5). Themes included: menstrual hygiene, soiling, irritation and infection, physical experience, knowledge of menstruation, psychological, social and cultural factors, and support from others. Those receiving reusable pads experienced improvements in comfort and reliability. This translated into reduced fears around garment soiling and related school absenteeism. Other menstrual hygiene challenges of washing, drying and privacy remained prominent. Puberty education improved girls' confidence to discuss menstruation and prompted additional support from teachers and peers. Findings have important implications for the development and evaluation of future interventions. Results suggest the provision of menstrual absorbents addresses one core barrier to menstrual health, but that interventions addressing broader needs such as privacy may improve effectiveness. Puberty education sessions should increase attention to body awareness and include strategies to address a wider range of practical menstrual challenges

    GIS is a powerful tool that may help to better manage natural resources. In this paper, we present a GIS model developed for the state of Morelos as an aid to determine whether a potential site, Loma de Mejia, met the Mexican Federal Guidelines. The Mexican Government has established federal guidelines for sanitary landfill site selection (NOM-083-SERMARNAT-2003). These guidelines were translated into a water-based Geographic Information System and applied to the state of Morelos, Mexico. For these examples, we used the SIGAM® (Sistema de Información Geográfico del Agua en México; a water-based GIS for Mexico) which has at least 60 layers from the National Water Commission (CONAGUA), the national mapping agency (INEGI; Instituto Nacional de Estadística, Geografía e Informática), NASA, and academic institutions. Results show that a GIS is a powerful tool that may allow federal, state and municipal policy makers to conduct an initial regional site reconnaissance rapidly. Once potential sites are selected, further characterization must be carried out in order to determine if proposed locations are suitable or not for a sanitary landfill. Based on the SIGAM© software, the Loma de Mejia would not comply with the Mexican Federal Guidelines.

    The demand for better hygiene has increased the need for developing more effective sanitation systems and facilities for the safe disposal of human urine and faeces. Non-Sewered Sanitary systems are considered to be one of the promising alternative solutions to the existing flush toilet system. An example of these systems is the Nano Membrane Toilet (NMT) system being developed at Cranfield University, which targets the safe disposal of human waste while generating power and recovering water. The NMT will generate energy from the conversion of human waste with the use of a micro-combustor; the heat produced will power a Stirling engine connected to a linear alternator to generate electricity. This study presents a numerical investigation of the thermodynamic analysis and operational characteristics of a quasi steady state model of the gamma type Stirling engine integrated into a combustor in the back end of the NMT system. The effects of the working gas, at different temperatures, on the Stirling engine performance are also presented. The results show that with the heater temperature of 390 °C from the heat supply via conduction at 820 W from the flue gas, the Stirling engine generates a daily power output of 27 Wh/h at a frequency of 23.85 Hz.

    In the children and adolescents of the Russian Federation, there is an increase in the incidence of a number of nosological entities, a significant prevalence of chronic diseases, and a reduction in health quality in children. According to the statistical data, in the past 5 years, the overall incidence has increased by 16% in children (aged 0-14 years) (171268 per 100,000 children in 2005) by 18% in adolescents. The incidence of diseases of blood and blood-forming organs, anemias, as well diseases of the respiratory, urogenital, and nervous systems, and congenital anomalies continues to increase. Along with socioeconomic causes, this is all due to the negative influence of environmental factors, dietary defects, and, in some cases, poor upbringing and teaching conditions, which do not comply with the hygienic standards and sanitary rules. Under the established conditions, the maintenance and improvement of children's health is the most important state task, the provision of their sanitary and epidemiological welfare being one of the major constituents in its accomplishment. In the past 3 years, the principal state sanitary inspector has issued 17 regulations on different aspects of the sanitary and epidemiological well-being of children and adolescents. The preparation of the draft "National Program for the Prevention of Adverse Health Influence of Environmental Factors for the Sake of the Future of Children and Adolescents for 2007-2010" has been currently completed.

    his study was undertaken to evaluate the possibility of disposing low-level radioactive waste in sanitary landfills with leachate containment to prevent environmental releases. To meet this objective, two simulated landfills, each 200 l. in volume and containing 55 kg of municipal refuse, were operated in the laboratory with simulated rainfall additions for a 9-month period to observe the extent to which radio-cobalt, -cesium, -strontium and tritium were leached into the liquid phase. One of the units was operated with leachate recycle, the other as a single pass control. Liquid samples were analyzed weekly for 3H, 58Co, 85Sr and 134Cs tracers. Weekly analyses were also performed for approximately 30 parameters to define the degree of stabilization of the waste. Major parameters included BOD, COD, pH and concentrations of specific organics, metals and gases. Concentrations of stable cobalt, strontium and cesium were also measured periodically. Soluble radioactivity levels in both systems were reduced by factors of 50 for 58Co, 5 for 85Sr and 7 for 134Cs, taking radioactive decay and dilution into account. Some radionuclide removal from the liquid phase was associated with major chemical changes in the landfills that occurred within 80 days for the control system and within 130 days for the recycle unit. Observed acid, sulfide, and CO2 concentrations suggested mechanisms for removing some of the radionuclides from leachate. Detection of 3H in the off-gas indicated that less than 1% of tritiated waste became airborne. The waste in the leachate recycle unit was more completely stabilized than in the control unit.

What matters is whether any disposal technology would lead to obvious social benefits. A waste disposal plan which is well linked or integrated with the community will ensure its acceptance. Local authorities will be challenged to identify solid waste disposal sites that are technically appropriate and also socially desirable.

    The Rockefeller Sanitary Commission for the Eradication of Hookworm Disease (1909–1914) fielded a philanthropic public health project that had three goals: to estimate hookworm prevalence in the American South, provide treatment, and eradicate the disease. Activities covered 11 Southern states, and Rockefeller teams found that about 40% of the population surveyed was infected. However, the commission met strong resistance and lacked the time and resources to achieve universal county coverage and meet project goals. We explore how these constraints triggered project changes that systematically reshaped project operations and the characteristics of the counties surveyed and treated. We show that county selectivity reduced the project’s initial potential to affect hookworm prevalence estimates, treatment, and eradication in the American South. PMID:24228676

    Palytoxin (PLTX), one the most potent marine toxins, and/or its analogs, have been identified in different marine organisms, such as Palythoa soft corals, Ostreopsis dinoflagellates, and Trichodesmium cyanobacteria. Although the main concern for human health is PLTXs entrance in the human food chain, there is growing evidence of adverse effects associated with inhalational, cutaneous, and/or ocular exposure to aquarium soft corals contaminated by PLTXs or aquaria waters. Indeed, the number of case reports describing human poisonings after handling these cnidarians is continuously increasing. In general, the signs and symptoms involve mainly the respiratory (rhinorrhea and coughing), skeletomuscular (myalgia, weakness, spasms), cardiovascular (electrocardiogram alterations), gastrointestinal (nausea), and nervous (paresthesia, ataxia, tremors) systems or apparates. The widespread phenomenon, the entity of the signs and symptoms of poisoning and the lack of control in the trade of corals as aquaria decorative elements led to consider these poisonings an emerging sanitary problem. This review summarizes literature data on human poisonings due to, or ascribed to, PLTX-containing soft corals, focusing on the different PLTX congeners identified in these organisms and their toxic potential.

    Microbiological pollution of drinking water is a major health problem in the suburbs of the Albanian capital. Intermittent supply and contamination, resulting in several gastrointestinal manifestations, are the main concerns for the population and health workers. The risk of outbreaks of water-borne diseases is high. Pollution originates from contamination of drinking water with domestic sewage. This research investigated the drinking water cycle from its natural source to the consumer, analysing samples and verifying pollution levels in the microbiological and chemical setting. The most important pollution sources were found in the distribution network, due to cross-contamination with sewers and illegal connections. The second pollution source was found around the extraction wells. This is related to abusive constructions within the sanitary zone around the wells and maybe the highly sewage-contaminated river water which feeds the aquifer.

    1993-03-30

    The Freeway Sanitary Landfill National Priorities List (NPL) site in Burnsville, Minnesota is situated in the Lower Minnesota River Valley. Shallow groundwater beneath the site is contaminated with low levels of volatile organic hydrocarbons and heavy metals. Under current conditions, no human exposures to site-related contaminants are known to occur at levels of health concern. Based on currently available information, the Minnesota Department of Health concludes that the site poses an indeterminate public health hazard under current conditions because exposure to volatile gases released to the air is possible, but cannot be evaluated from the very limited information available. Theremore » are also a few physical hazards on the site which pose a risk of accident or injury if trespassing occurs. Otherwise, there are no indications that people have been, or are being, exposed to site-related contaminants at levels that would be of health concern. The Agency For Toxic Substances and Disease Registry (ATSDR) Health Activities Recommendation Panel has evaluated the Freeway Sanitary Landfill Public Health Assessment for appropriate follow-up activities. The Panel has recommended that health education be considered to assist site workers in better understanding their potential for exposure to landfill gases.« less

  17. Social life and sanitary risks: evolutionary and current ecological conditions determine waste management in leaf-cutting ants

    Adequate waste management is vital for the success of social life, because waste accumulation increases sanitary risks in dense societies. We explored why different leaf-cutting ants (LCA) species locate their waste in internal nest chambers or external piles, including ecological context and accounting for phylogenetic relations. We propose that waste location depends on whether the environmental conditions enhance or reduce the risk of infection. We obtained the geographical range, habitat and refuse location of LCA from published literature, and experimentally determined whether pathogens on ant waste survived to the high soil temperatures typical of xeric habitats. The habitat of the LCA determined waste location after phylogenetic correction: species with external waste piles mainly occur in xeric environments, whereas those with internal waste chambers mainly inhabit more humid habitats. The ancestral reconstruction suggests that dumping waste externally is less derived than digging waste nest chambers. Empirical results showed that high soil surface temperatures reduce pathogen prevalence from LCA waste. We proposed that LCA living in environments unfavourable for pathogens (i.e. xeric habitats) avoid digging costs by dumping the refuse above ground. Conversely, in environments suitable for pathogens, LCA species prevent the spread of diseases by storing waste underground, presumably, a behaviour that contributed to the colonization of humid habitats. These results highlight the adaptation of organisms to the hygienic challenges of social living, and illustrate how sanitary behaviours can result from a combination of evolutionary history and current environmental conditions.

    The aim of this paper is to show sanitary care organization in the 1st infantry battalion of 7th Puma Brigade during attacks at the Dinara mountain in the Winter 94 operation, and to compare it with the general pattern described. The problems encountered and mistakes made in the medical care organization that were caused either by the lack of coordination between the command and military personnel or the lack of equipment, inadequate equipment, geographical characteristics of the area, communication problems, weather conditions or any other reason influencing sanitary care are presented. Based on the analysis of two cases, it is concluded that sanitary care was organizaed according to the echelon principles. During the war, medical care was satisfactory in spite of all the problems and shortcomings, mainly owing to the young, brave and enthusiastic command and medical personnel. Medical care in the Croatian Army during the war was an integral part of the military-civilian health care system. Despite rather common problems and deficiencies, the achievements in taking care of the wounded and sick persons were satisfactory, all the wounded men were properly managed, functionally and cosmetically recovered, and capable of normal living and work. These results were especially gratifying since they were, in general, recorded in young men.

  1. The impact of photoperiod insensitive Ppd-1a mutations on the photoperiod pathway across the three genomes of hexaploid wheat (Triticum aestivum).

    Shaw, Lindsay M; Turner, Adrian S; Laurie, David A

    2012-07-01

    Flowering time is a trait that has been extensively altered during wheat domestication, enabling it to be highly productive in diverse environments and providing a rich source of variation for studying adaptation mechanisms. Hexaploid wheat is ancestrally a long-day plant, but many environments require varieties with photoperiod insensitivity (PI) that can flower in short days. PI results from mutations in the Ppd-1 gene on the A, B or D genomes, with individual mutations conferring different degrees of earliness. The basis of this is poorly understood. Using a common genetic background, the effects of A, B and D genome PI mutations on genes of the circadian clock and photoperiod pathway were studied using genome-specific expression assays. Ppd-1 PI mutations did not affect the clock or immediate clock outputs, but affected TaCO1 and TaFT1, with a reduction in TaCO1 expression as TaFT1 expression increased. Therefore, although Ppd-1 is related to PRR genes of the Arabidopsis circadian clock, Ppd-1 affects flowering by an alternative route, most likely by upregulating TaFT1 with a feedback effect that reduces TaCO1 expression. Individual genes in the circadian clock and photoperiod pathway were predominantly expressed from one genome, and there was no genome specificity in Ppd-1 action. Lines combining PI mutations on two or three genomes had enhanced earliness with higher levels, but not earlier induction, of TaFT1, showing that there is a direct quantitative relationship between Ppd-1 mutations, TaFT1 expression and flowering. © 2012 The Authors.

    Livestock food systems play key subsistence and income generation roles in low to middle income countries and are important networks for zoonotic disease transmission. The aim of this study was to use a value chain framework to characterize the broiler chicken meat system of Nairobi, its governance and sanitary risks. A total of 4 focus groups and 8 key informant interviews were used to collect cross-sectional data from: small-scale broiler farmers in selected Nairobi peri-urban and informal settlement areas; medium to large integrated broiler production companies; traders and meat inspectors in live chicken and chicken meat markets in Nairobi. Qualitative data were collected on types of people operating in the system, their interactions, sanitary measures in place, sourcing and selling of broiler chickens and products. Framework analysis was used to identify governance themes and risky sanitary practices present in the system. One large company was identified to supply 60% of Nairobi's day-old chicks to farmers, mainly through agrovet shops. Broiler meat products from integrated companies were sold in high-end retailers whereas their low value products were channelled through independent traders to consumers in informal settlements. Peri-urban small-scale farmers reported to slaughter the broilers on the farm and to sell carcasses to retailers (hotels and butcheries mainly) through brokers (80%), while farmers in the informal settlement reported to sell their broilers live to retailers (butcheries, hotels and hawkers mainly) directly. Broiler heads and legs were sold in informal settlements via roadside vendors. Sanitary risks identified were related to lack of biosecurity, cold chain and access to water, poor hygiene practices, lack of inspection at farm slaughter and limited health inspection in markets.
 Large companies dominated the governance of the broiler system through the control of day-old chick production. Overall government control was described as

    Polyelectrolytes used in the practice of water supply to the population were comparatively hygienically studied, by using a complex of hazard indices and a new approach to sanitary-and-epidemiological evaluation of the safety of water-soluble polymers is substantiated. The anionic and cationic flocculating agents from different chemical classes, such as Superflok A-100, Fennopol A 321E, Fennopol K 221E, Praestol 2530 TR, VPK-402, Superflok C-577, Saipan, KF-91, Ecosol-401, a low molecular-weight sodium polyacrylate were tested as model compounds. Moreover, the information already available in the scientific literature on the toxicity of synthetic polyelectrolytes was analyzed. The generalized maximum permissible concentrations were substantiated for individual chemical classes of synthetic polyelectrolytes: polyacrylamides, polyamines, polydiallyldimethylammonium chloride.

    Sarcocystis fayeri (S. fayeri) is a newly identified causative agent of foodborne disease that is associated with the consumption of raw horse meat. The testing methods prescribed by the Ministry of Health, Labour and Welfare of Japan are time consuming and require the use of expensive equipment and a high level of technical expertise. Accordingly, these methods are not suitable for use in the routine sanitary control setting to prevent outbreaks of foodborne disease. In order to solve these problems, we have developed a new, rapid and simple testing method using LAMP, which takes only 1 hour to perform and which does not involve the use of any expensive equipment or expert techniques. For the validation of this method, an inter-laboratory study was performed among 5 institutes using 10 samples infected with various concentrations of S. fayeri. The results of the inter-laboratory study demonstrated that our LAMP method could detect S. fayeri at concentrations greater than 10(4) copies/g. Thus, this new method could be useful in screening for S. fayeri as a routine sanitary control procedure.

    The infectious Salmon Anemia virus (ISAv) is a pathogen that mainly affects the Atlantic Salmon (Salmo salar). It was detected in Norway in 1984 and in June 2007 appeared in Chile, producing a drop of more than 30% in the country's production level. It is expected that with certain regularity, outbreaks will continue to appear in Chile without the need of reintroducing the virus from foreign countries. We present a numerical study of the influence of winds and tides in the dispersion of lagrangian particles to simulate the transport of ISAv in the Aysen region, in southern Chile. This study combines the use of numerical models of the ocean and atmosphere, lagrangian tracking and biological aspects of ISAv infections. As in previous results, a wider dispersion of ISAv was observed during spring tides. Temporal changes in wind significantly modified the transport of viral particles from an infected center. Under similar forcing conditions, the areas of risk associated to culture sites separated by a few kilometers could be very different. Our main results remark the importance of the use of a detailed knowledge of hydrographic and atmospheric circulation in the definition of boundaries for sanitary management areas. We suggest that a methodology similar to the one presented in this study should be considered to define sanitary strategies to minimize the occurrence of native outbreaks of ISAv.

    We investigated 33 pharmaceuticals and personal care products (PPCPs) with emphasis on anthelmintics and their metabolites in human sanitary waste treatment plants (HTPs), sewage treatment plants (STPs), hospital wastewater treatment plants (HWTPs), livestock wastewater treatment plants (LWTPs), river water and seawater. PPCPs showed the characteristic specific occurrence patterns according to wastewater sources. The LWTPs and HTPs showed higher levels (maximum 3000 times in influents) of anthelmintics than other wastewater treatment plants, indicating that livestock wastewater and human sanitary waste are one of principal sources of anthelmintics. Among anthelmintics, fenbendazole and its metabolites are relatively high in the LWTPs, while human anthelmintics such as albendazole and flubendazole are most dominant in the HTPs, STPs and HWTPs. The occurrence pattern of fenbendazole's metabolites in water was different from pharmacokinetics studies, showing the possibility of transformation mechanism other than the metabolism in animal bodies by some processes unknown to us. The river water and seawater are generally affected by the point sources, but the distribution patterns in some receiving water are slightly different from the effluent, indicating the influence of non-point sources.

It is established that the in acting regulations the classification of enterprises recycling of non-ferrous metals, fails to take into account such the hazard risks criteria of the enterprise, as volume of emissions of priority substances, the height of their arrival in the atmosphere, etc., and also does not take into account increased significantly in the current time processing volumes. The results of the performed research allowed to offer new positions in the classification of production of secondary lead from used batteries (I to IV class), depending on the volume of production (from 20 000 to 160 000 tons per year), the amount of emissions of lead (0.2 to 1, 6 tons per year) and release height (15 to 60 m).

    The appropriate treatment of sanitary landfill leachate is one of the greatest challenges nowadays due to the large volumes of solid waste generated. Thus, the aim of this study is to evaluate the performance of different routes involving the integration of advanced oxidation processes based on Fenton's reagents (AOP-Fenton) and microfiltration (MF) and nanofiltration (NF) membrane processes for the treatment of landfill leachate. MF module configuration (submerged or sidestream) and MF and NF recovery rate were evaluated. The combination of AOP-Fenton, MF and NF proved to be an effective treatment for landfill leachate. High removal efficiencies of chemical oxidation demand (94-96%) and colour (96-99%) were obtained. The configuration named route 3, composed of MF of raw landfill leachate (MF1), POA-Fenton-MF2 of the MF1 concentrate and NF of both MF1 and MF2 permeates, showed a higher global water recovery and was responsible for lower waste generation. It was considered the best one in terms of environmental, technical and economical aspects.

    Palestinian inhabitants have disposed of their solid wastes at open dumpsites over the past 40 years without an adequate solid waste management (SWM) plans. Recently, the Palestinian Authority initiated SWM planning to establish controlled sanitary landfills, based on a participatory approach. The purpose of this study was to assess public concerns about existing solid waste dumpsites and public perceptions of sanitary landfill site selection. The study will also take into consideration the effect of diverse social, economic, and environmental related factors of the inhabitants on sitting suitable landfill sites in three Palestinian districts in the West Bank, namely, "Nablus," "Salfit," and "Ramallah and Al-Bireh." The results of this study showed that 64.9% of the sample population are aware of the problems and potential impacts associated with random dumpsites, and 41.6% think that they are suffering from the dumps. Among the environmental, socioeconomic, and political factors, the environmental factors, air pollution in particular, are thought be the most important consideration in selecting a landfill site. The "fairness in selecting a landfill site" was chosen to be one of the most important socioeconomic factors, possibly as a reaction to the Israeli occupation and subsequent land use restrictions in the West Bank, Palestinian territory.

    Emergency field medical facilities constructed after a disaster are frequently managed by medical staff even though many of the day-to-day problems of hospital management are unrelated to medicine. In this paper we discuss the short-term management of one of these problems, namely the control and disposal of sanitary wastes. It is aimed at persons in the medical profession who may find themselves responsible for a temporary hospital and have little or no previous experience of managing such situations. The wastes commonly generated are excreta, sullage and refuse. In addition, surface water must also be considered because its inadequate disposal is a potential health hazard. The paper concentrates on short-term measures appropriate for the first six months of the hospital or clinic's existence. Facilities expected to last longer are recommended to install conventional waste management systems appropriate to the local community and conditions. In most situations, wastes should be disposed of underground either by burial (for solids) or infiltration (for liquids). The design, construction and management of appropriate disposal systems are described.

    Autism is a developmental disorder that it is characterized by a qualitative alteration of social interaction, communication and repetitive and stereotyped behaviours, interests and activities. Recent studies about health are showing that people with autism have lower hope of life. Among other causes, difficulty to identify and to communicate uneasiness and resistance to allow medical explorations are important factors to consider. To design and to implant a specific program for people with Autistic Spectrum Disorder (ASD) with the objective of habituating them to the medical explorations so that they admit it and collaborate, facilitating the sanitary personnel's work. Our aim was to evaluate the effectiveness of the program and the maintenance of the potentials improvements. Our sample was formed by twenty-two children with ASD (mean chronological age, 9;10 years). A quasi-experimental design of interrupted temporary series was carried out. two grouping variables (clinical characteristics of the groups about QI and about linguistic abilities) as dependent variable a measure of percentage of success has been used through an observation protocol designed for this program. Improvements in all the groups. Results are not conditioned neither for the level of intellectual abilities (IQ) neither for the existence or not of linguistic abilities. Likewise, it is found that carrying out maintenance sessions in period of seven weeks allows to maintain long term achievements reached by the program. However, we found that those children which were severely impaired could obtain more benefit from more frequent maintenance sessions.

    Wastewater collection systems are an important component of proper management of wastewater to prevent environmental and human health implications from mismanagement of anthropogenic waste. Due to aging and inadequate asset management practices, the wastewater collection assets of many cities around the globe are in a state of rapid decline and in need of urgent attention. Risk management is a tool which can help prioritize resources to better manage and rehabilitate wastewater collection systems. In this study, a risk matrix and a weighted sum multi-criteria decision-matrix are used to assess the consequence and risk of sewer pipe failure for a mid-sized city, using ArcGIS. The methodology shows that six percent of the uninspected sewer pipe assets of the case study have a high consequence of failure while four percent of the assets have a high risk of failure and hence provide priorities for inspection. A map incorporating risk of sewer pipe failure and consequence is developed to facilitate future planning, rehabilitation and maintenance programs. The consequence of failure assessment also includes a novel failure impact factor which captures the effect of structurally defective stormwater pipes on the failure assessment. The methodology recommended in this study can serve as a basis for future planning and decision making and has the potential to be universally applied by municipal sewer pipe asset managers globally to effectively manage the sanitary sewer pipe infrastructure within their jurisdiction.

    Identifying and promoting new management techniques for the descentralized pneumology hospitals or wards was one of the most ambitious objectives of the project "Quality in the pneumology medical services through continuous medical education and organizational flexibility", financed by the Human Resourses Development Sectorial Operational Programme 2007-2013 (ID 58451). The "Medium term Strategy on the specific management of the pneumology hospitals or wards after the descentralization of the sanitary system" presented in the article was written by the project's experts and discussed with pneumology managers and local authorities representatives. This Strategy application depends on the colaboration of the pneumology hospitals with professional associations, and local and central authorities.

    The total amount of solid waste generated in Alexandria is 2820 tons/d which increases to 3425 tons/day during summer. In the past, 77% of the collected solid wastes was open dumped. The open dumping sites did not have the minimum requirements for pollution control. Following the exacerbation of the problem, the Alexandria Governorate contracted a company to carry out the solid waste management. The contracted company transferred 75% of the daily generated solid wastes to a new constructed sanitary lanfill. The site receives a daily average of 1910 tons. The landfilling is performed by trench method in the form of cells. The produced leachate is discharged into two lined aerated lagoons. The biogas formed from biodegradation of landfilled solid wastes is burned and the produced heat is used for drying the lagoons leachate. The remaining residues are relandfilled. The study aims at assessment of the solid waste sanitary landfill leachate characterization and its impacts on the groundwater. The analysis of the collected data confirms that leachates from the landfill are severely contaminated with organics, salts, and heavy metals. The fluctuations in concentration levels of the different parameters were attributed to aging and thickness of waste layers, stage of decomposition, and re-landfilling of the concentrated residues from the drying lagoons. The concentrations of NH4-N (600 mg/l) indicated that the process of stabilization was still in the initial stages and attributed to the compaction process. The high BOD5 results (28,833 mg/l) indicated that the process of stabilization was in the initial stages which were very slow. The high COD results (45,240 mg/l) can be attributed to the compaction of the wastes which also retards the degradation of the solid wastes. The BOD and COD values indicated clearly severe contamination. The BOD5/COD ratio measured in the current study (0.64) indicated that the leachate of the present study was biodegradable and unstabilized

    Larval morphology is documented using both light and scanning electron microscopy for all three instars of the muscid fly Atherigona orientalis (Schiner), which is a species of known sanitary and forensic importance found in tropical and subtropical areas of all biogeographic regions. The unpaired sclerite in a form of a spicule is reported herein in the second and the third instar larvae. Occurrence of this sclerite was hitherto unknown in the second instar larvae of Muscidae and was only known from the third instar of several species, however not in a form of a spicule. Our study is the first report of the occurrence of the "sensory organ X" in all three larval instars of a species representing the family Muscidae. The bubble membrane, previously known only from third instar cyclorrhaphan larvae, is reported herein for the first time in the second instar. Characters allowing for discrimination of A. orientalis larvae from other forensically important Muscidae are summarised. Copyright © 2014 Elsevier B.V. All rights reserved.

    The consumption of lacteal desserts in the province of Santa Cruz de Tenerife is notably high. However, there are no legal standards in Spain regarding microbiological quality. For this reason, we have decided that it would be of interest to carry out a health-sanitary study of these products, with the aim of discovering their microbial content. 330 samples of lacteal desserts on sale in the province of Santa Cruz de Tenerife have undergone analysis. They have been divided into three groups: cream caramel (egg and vanilla) (80), mousse (60) and the third group, known as "other desserts", which includes custard and the rest of lacteal desserts not included in the previous groupings (190). Neither E. coli, Salmonella spp., Shigella spp., nor Staphylococcus aureus have been detected in any of the samples analysed. In spite of the fact that the results obtained do not reflect high microbiological contamination, we consider it necessary to lay down legal standards, with reference values, for these lacteal products, which will guarantee good microbiological quality.

    Quantifying rainfall-derived inflow and infiltration (RDII) in a sanitary sewer is difficult when RDII and overflow occur simultaneously. This study proposes a novel conductivity-based method for estimating RDII. The method separately decomposes rainfall-derived inflow (RDI) and rainfall-induced infiltration (RII) on the basis of conductivity data. Fast Fourier transform was adopted to analyze variations in the flow and water quality during dry weather. Nonlinear curve fitting based on the least squares algorithm was used to optimize parameters in the proposed RDII model. The method was successfully applied to real-life case studies, in which inflow and infiltration were successfully estimated for three typical rainfall events with total rainfall volumes of 6.25 mm (light), 28.15 mm (medium), and 178 mm (heavy). Uncertainties of model parameters were estimated using the generalized likelihood uncertainty estimation (GLUE) method and were found to be acceptable. Compared with traditional flow-based methods, the proposed approach exhibits distinct advantages in estimating RDII and overflow, particularly when the two processes happen simultaneously.

    A study was conducted in 2014–15 by the U.S. Geological Survey (USGS), in cooperation with the Municipality of Caguas, to determine if changes in the stream sanitary quality during base-flow conditions have occurred since 1997–99, when a similar study was completed by the USGS. Water samples were collected for the current study during two synoptic surveys in 2014 and 2015. Water samples were analyzed for fecal and total coliform bacteria, nitrate plus nitrite as nitrogen, nitrogen and oxygen isotopes of nitrate, and human health and pharmaceutical products. Water sampling occurred at 39 stream locations used during the 1997–99 study by the USGS and at 11 additional sites. A total of 151 stream miles were classified on the basis of fecal and total coliform bacteria results.The overall spatial pattern of the sanitary quality of surface water during 2014–15 is similar to the pattern observed in 1997–99 in relation to the standards adopted by the Puerto Rico Environmental Quality Board in 1990. Surface water at most of the water-sampling sites exceeded the current standard for fecal coliform of 200 colonies per 100 milliliters adopted by the Puerto Rico Environmental Quality Board in 2010. The poorest sanitary quality was within the urban area of the Municipality of Caguas, particularly in urban stream reaches of Río Caguitas and in rural and suburban reaches bordered by houses in high density that either have inadequate septic tanks or discharge domestic wastewater directly into the stream channels. The best sanitary quality occurred in areas having little or no human development, such as in the wards of San Salvador and Beatriz to the south and southwest of Caguas, respectively. The concentration of nitrate plus nitrite as nitrogen ranged from 0.02 to 9.0 milligrams per liter, and did not exceed the U.S. Environmental Protection Agency drinking-water standard for nitrate as nitrogen of 10 milligrams per liter. The composition of nitrogen and oxygen

    Highlights: Black-Right-Pointing-Pointer Open dumping is the most common form of waste disposal in neglected small cities. Black-Right-Pointing-Pointer Semi-mechanized landfills can be a sustainable option for small cities. Black-Right-Pointing-Pointer We present the theory of design and operation of semi-mechanized landfills. Black-Right-Pointing-Pointer Villanueva, Honduras has operated its semi-mechanized landfill for 15 years. Black-Right-Pointing-Pointer The cost of operation is USmore » $$4.60/ton with a land requirement of 0.2m{sup 2}/person-year. - Abstract: Open dumping is the most common practice for the disposal of urban solid wastes in the least developed regions of Africa, Asia and Latin America. Sanitary landfill design and operation has traditionally focused on large cities, but cities with fewer than 50,000 in population can comprise from 6% to 45% of a given country's total population. These thousands of small cities cannot afford to operate a sanitary landfill in the way it is proposed for large cities, where heavy equipment is used to spread and compact the waste in daily cells, and then to excavate, transport and apply daily cover, and leachate is managed with collection and treatment systems. This paper presents an alternative approach for small cities, known as the semi-mechanized trench method, which was developed in Villanueva, Honduras. In the semi-mechanized trench method a hydraulic excavator is used for 1-3 days to dig a trench that will last at least a month before it is filled with waste. Trucks can easily unload their wastes into the trench, and the wastes compact naturally due to semi-aerobic biodegradation, after which the trenches are refilled and covered. The exposed surface area is minimal since only the top surface of the wastes is exposed, the remainder being covered by the sides and bottom of the trench. The surplus material from trench excavation can be valorized for use as engineering fill onsite or off. The landfill in

    The U.S. Geological Survey (USGS) is responsible for monitoring flows in the Chicago Sanitary and Ship Canal (CSSC) near Lemont, Illinois, as a part of the Lake Michigan Diversion Accounting overseen by the U.S. Army Corps of Engineers, Chicago District. Lake Michigan Diversion Accounting is mandated by a U.S. Supreme Court decree in order to monitor, and limit, the State of Illinois’ annual diversion of Great Lakes water through the manmade CSSC. Every 5 years, a technical review committee consisting of practicing engineers and academics reviews USGS streamgaging practices in the CSSC near Lemont, Illinois. The sixth technical review committee expressed concern that the index-velocity rating—the method used to estimate mean cross-sectional velocity from a measured index velocity—may be subject to hysteresis at this site because of the unique, unsteady hydraulics of the canal. Hysteresis in index-velocity ratings can occur at sites where the flow distribution in the channel varies significantly between the rising and falling limbs of the hydrograph for the same discharge. Presently, hysteresis in index-velocity ratings has been documented only in tidally affected sites. This report investigates whether hysteresis can occur at this nontidal site, and the conditions under which it is likely to occur, by using both a theoretical approach and a three-dimensional hydrodynamic model. The theoretical analysis investigated the conditions required for hysteresis in the index-velocity rating, and the modeling analysis focused on the effect of the timing of the inflows from the CSSC and the Cal-Sag Channel on the potential for hysteresis and whether highly resolved simulations of actual high-flow events show any evidence of hysteresis. Based on both a theoretical analysis using observed historical data and an analysis using a three-dimensional hydrodynamic model, there is no conclusive evidence for the existence of hysteresis in the index-velocity rating at the USGS

    Background The design and development of school health programmes will require information at demographic characteristics of schoolchildren and the major health burdens of the school-age group, the opportunities for intervention and the appropriateness of the available infrastructure. This study aims to analyse demographic and parasitic infections status of schoolchildren and sanitary conditions of schools in Sanliurfa province of south-eastern Turkey. Method Three primary schools were randomly selected in the shantytown, apartment and rural districts. A total of 1820 schoolchildren between 7–14 years age were took part to the survey of whom 1120 (61.5%) were boys and 700 (38.4%) were girls. A child form (including child's name, sex, age, school grade and parasitic infections) and school survey form (including condition of water supply, condition of latrines, presence of soaps on the basins and presence of garbage piles around to the schools) were used for demographic, parasitic and sanitary surveys. Stool samples were examined by cellophane thick smear technique for the eggs of intestinal helminths. Results The demographic survey showed that number of schoolchildren was gradually decreased as their age's increase in shantytown school. The sex ratio was proportional until the second grade, after which the number of females gradually decreased in children in shantytown and rural schools while, in apartment area, schoolchildren was proportionally distributed between age groups and gender even the high-grade students. The prevalence of helminthic infections was %77.1 of the schoolchildren in shantytown, 53.2% in apartment district and 53.1% of rural area. Ascaris lumbricoides was the most prevalent species and followed by Trichuris trichiura, Hymenolepis nana and Taenia species in three schools. Sanitation survey indicated that the tap water was limited in shantytown school, toilet's sanitation was poor, available no soaps on lavatories and garbage piles were

    In 2016, the U.S. Fish and Wildlife Service, U.S. Geological Survey, and U.S. Army Corps of Engineers undertook a field study in the Chicago Sanitary and Ship Canal near Romeoville, Illinois to determine the influence of tow transit on the efficacy of the Electric Dispersal Barrier System (EDBS) in preventing the passage of juvenile fish (total length < 100 millimeters (mm)). Dual-frequency identification sonar data showed that large schools of juvenile fish (mean school size of 120 fish; n = 19) moved upstream and crossed the electric field of an array in the EDBS concurrent with downstream-bound (downbound) loaded tows in 89.5% of trials. Smaller schools of juvenile fish (mean school size of 98 fish; n = 15) moved downstream and crossed the electric field of an array in the EDBS concurrent with upstream-bound (upbound) loaded tows in 73.3% of trials. Observed fish passages through the EDBS were always opposite to the direction of tow movement, and not associated with propeller wash. These schools were not observed to breach the EDBS in the absence of a tow and showed no signs of incapacitation in the barrier during tow passage. Loaded tows transiting the EDBS create a return current of water flowing between the tow and the canal wall that typically travels opposite the direction of tow movement, and cause a decrease in the voltage gradient of the barrier of up to 88%. Return currents and decreases in voltage gradients induced by tow passage likely contributed to the observed fish passage through the EDBS. The efficacy of the EDBS in preventing the passage of small, wild fish is compromised while tows are moving across the barrier system. In particular, downbound tows moving through the EDBS create a pathway for the upstream movement of small fish, and therefore may increase the risk of transfer of invasive fishes from the Mississippi River Basin to the Great Lakes Basin.

To assess the utility of two ways for measuring satisfaction. Cross-sectional study carried out in people attending the administrative sections of Health Centres for diverse reasons. Just after the interaction with the administrative they were interviewed using two different questions for assessing their opinions and satisfaction with communicational and technical aspects related with their demands. Descriptive analysis. Significant differences among mean was explored by χ(2) test. Open-ended questions were grouped in categories in a process involving three researchers independently. Over than 90% (360) of the attendees declared to be satisfied or very satisfied with the service received from the staff personal. Nevertheless, among 18-36% gave suggestions for improving the service after their consultation. Independently the domain explored, people suggested the communicational, personal capability, quality and quantity of explanations and waiting time as the main aspects to be improved. Surveys with open-ended questions are more useful to assess the quality of the attention the citizens receive from no-sanitary staff in Health Centres. These type of questions are also more useful for detecting problems and planning new interventions. Relational and informative issues seem to be the most prioritary areas to improve in this section of Health Centres. Copyright © 2010 SECA. Published by Elsevier Espana. All rights reserved.

    Governments, multinational organisations, and charities have commenced the distribution of sanitary products to address current deficits in girls' menstrual management. The few effectiveness studies conducted have focused on health and education outcomes but have failed to provide quantitative assessment of girls' preferences, experiences of absorbents, and comfort. Objectives of the study were, first, to quantitatively describe girls' experiences with, and ratings of reliability and acceptability of different menstrual absorbents. Second, to compare ratings of freely-provided reusable pads (AFRIpads) to other existing methods of menstrual management. Finally, to assess differences in self-reported freedom of activity during menses according to menstrual absorbent. Cross-sectional, secondary analysis of data from the final survey of a controlled trial of reusable sanitary padand puberty education provision was undertaken. Participants were 205 menstruating schoolgirls from eight schools in rural Uganda. 72 girls who reported using the intervention-provided reusable pads were compared to those using existing improvised methods (predominately new or old cloth). Schoolgirls using reusable pads provided significantly higher ratings of perceived absorbent reliability across activities, less difficulties changing absorbents, and less disgust with cleaning absorbents. There were no significant differences in reports of outside garment soiling (OR 1.00 95%CI 0.51-1.99), or odour (0.84 95%CI 0.40-1.74) during the last menstrual period. When girls were asked if menstruation caused them to miss daily activities there were no differences between those using reusable pads and those using other existing methods. However, when asked about activities avoided during menstruation, those using reusable pads participated less in physical sports, working in the field, fetching water, and cooking. Reusable pads were rated favourably. This translated into some benefits for self

Serological studies of types A, B, and E botulinal toxins by passive hemagglutination and bentonite flocculation. J. Bacteriol. 91:967–974. 1966.—Formalinized sheep red blood cells (SRBC), sensitized with types A, B, and E botulinal toxoids and toxins by bis-diazotized benzidine (BDB), were tested against A, B, and E antitoxins prepared in horses and rabbits. Type B antitoxin cross-reacted with A toxoid SRBC, but the reciprocal cross-reaction was not observed. E toxin SRBC were specifically agglutinated by E antitoxin. Flocculation of antigen-sensitized bentonite particles was less sensitive in titration of antitoxin than hemagglutination. Also, reciprocal cross-reactions were observed between types A and B antitoxins. Cross-reactions in both serological tests were eliminated by titration of antitoxins in the presence of the heterologous antigens, with no inhibitory effect on the homologous antitoxins. Generally, equine antitoxins were less suitable for agglutinations, especially of antigen-sensitized bentonite particles. Types A, B, and E antitoxins were specifically inhibited by 43, 39, and 245 mouse ld50 of their respective homologous toxins in the hemagglutination-inhibition test. A, B, and E antitoxins were specifically inhibited by 500, 950, and 1,500 mouse ld50 of their respective homologous toxins in bentonite flocculation inhibitions. Formalinized SRBC sensitized with rabbit types A and B antitoxins by BDB were respectively clumped by as little as 0.75 to 1.3 mouse ld50 of A toxin and 2.3 ld50 of B toxin, whereas bentonite particles sensitized by the same antitoxins were specifically clumped by 150 ld50 of A toxin and 630 ld50 of B toxin. E antitoxin sensitization of SRBC or bentonite particles was not successful. Evidence is presented that indicates that the serological procedures are applicable to the detection of botulinal toxins

    Guanabara Bay is the second largest bay in the coast of Brazil, with an area of 384 km2. In its surroundings live circa 16 million inhabitants, out of which 6 million live in Rio de Janeiro city, one of the largest cities of the country, and the host of the 2016 Olympic Games. Anthropogenic interference in Guanabara Bay area started early in the XVI century, but environmental impacts escalated from 1930, when this region underwent an industrialization process. Herein we present an overview of the current environmental and sanitary conditions of Guanabara Bay, a consequence of all these decades of impacts. We will focus on microbial communities, how they may affect higher trophic levels of the aquatic community and also human health. The anthropogenic impacts in the bay are flagged by heavy eutrophication and by the emergence of pathogenic microorganisms that are either carried by domestic and/or hospital waste (e.g., virus, KPC-producing bacteria, and fecal coliforms), or that proliferate in such conditions (e.g., vibrios). Antibiotic resistance genes are commonly found in metagenomes of Guanabara Bay planktonic microorganisms. Furthermore, eutrophication results in recurrent algal blooms, with signs of a shift toward flagellated, mixotrophic groups, including several potentially harmful species. A recent large-scale fish kill episode, and a long trend decrease in fish stocks also reflects the bay’s degraded water quality. Although pollution of Guanabara Bay is not a recent problem, the hosting of the 2016 Olympic Games propelled the government to launch a series of plans to restore the bay’s water quality. If all plans are fully implemented, the restoration of Guanabara Bay and its shores may be one of the best legacies of the Olympic Games in Rio de Janeiro. PMID:26635734

    2008-01-01

    During the eighties a large increase in latex gloves production was observed because of the high demand of gloves in health care settings. In this period a low compliance to minimal quality standard was detected and the poor glove quality was associated with an increase of both irritant and allergic glove-related diseases. Since the second half of nineties health care workers and manufacturers paid more attention to these problems and a trend to a gradual, even if slow, quality improvement was observed. Most frequently powder-free gloves and synthetic gloves were offered on the market. The aim of this study was to highlight what has improved about materials and types of sanitary gloves during the last ten years. The information are based on a review of the scientific literature and practical experiences. Today a large selection of gloves made of different materials are available and they should be addressed to specific tasks. The review of the scientific literature and the analysis of many technical sheets provided by the manufacturers pointed out a trend to a better latex gloves quality (less chemical additives and generally a lower total protein content); sometimes data about a lower extractable latex allergens content are also available. Unfortunately detailed information on glove composition are not usually provided by the manufacturers; purchasers should require the manufacturing company to give comprehensive information and verify their reliability. Moreover the regulation in force should be adapted to higher quality standards. Powder-free and synthetic gloves consumption has improved but the use of synthetic rubber gloves should be further enhanced since some materials (e.g. neoprene and nitrile rubber) have a good biocompatibility and seem to have physical properties and protective efficacy similar to latex. Moreover allergic reactions to synthetic gloves (some chemical additives) are only occasional.

    To maximise the benefits of globalisation, countries and their stakeholders must become familiar with and adhere to the rights and obligations set out by the World Trade Organization under the Agreement on Sanitary and Phytosanitary Measures. Furthermore, for trade in animals and animal products, they must adhere to the standards, guidelines and recommendations established by the OIE (World organisation for animal health), which also encourages participation of countries in the standard-setting process. Only after implementing these requirements and strengthening veterinary infrastructures and surveillance and monitoring systems, will countries be able to fully benefit from the new international trade rules.

    This commentary uses a recent article in the press about the failure of the Gates Foundation's plans to eradicate poliomyelitis in Asia and Africa as a basis for discussing the often limited historical role that vaccines have played in controlling many infectious diseases when compared to increases in living standards. A recent book on the Epidemic Intelligence Service of the Centers for Disease Control and Prevention, USA, is used to illustrate the importance of epidemiological surveillance and public health laboratories in past and present efforts to control infectious diseases. On the basis of these publications, the author discusses and proposes solutions for some of the shortcomings of the Chilean sanitary services demonstrated when dealing with a recent epidemic of more than 26, 000 cases of acute diarrhea in the Northern Chilean city of Antofagasta.

    To compare the interval between death and enucleation (ΔT-O-E), between enucleation and preservation (ΔT-E-P) and the quality of the cornea before and after the implantation of new technique and sanitary rules. A retrospective study that evaluated the records of cornea donors in Sao Paulo's Santa Casa Eye Tissue Bank 2 years before and 2 years after the implementation new sanitary rules. An increase was observed in the absolute number of 205 to 374 donors following the adopted changes. There was no statistically significant difference in Δt-O-E and ΔT-E-P before and after the implemented changes. Of the total of 1,105 donor corneas, 388 donor corneas were observed before the changes and 717 donor corneas after the implemented changes. We observed a statistically significant increase in grading of donor cornea quality from 1.76 ± 0.90 to 1.94 ± 0.88 after the implementation of new standards of resolution. After the changes required by Resolution 347, there was a large increase in the number of donated, taken and preserved corneas. The BTO has not diminished the ΔT O-E and ΔT E-P. Cornea quality presented itself lower after the new rules.

  3. Imaging through ground-level turbulence by Fourier telescopy: Simulations and preliminary experiments

    NASA Astrophysics Data System (ADS)

    Randunu Pathirannehelage, Nishantha

    Fourier telescopy imaging is a recently-developed imaging method that relies on active structured-light illumination of the object. Reflected/scattered light is measured by a large "light bucket" detector; processing of the detected signal yields the magnitude and phase of spatial frequency components of the object reflectance or transmittance function. An inverse Fourier transform results in the image. In 2012 a novel method, known as time-average Fourier telescopy (TAFT), was introduced by William T. Rhodes as a means for diffraction-limited imaging through ground-level atmospheric turbulence. This method, which can be applied to long horizontal-path terrestrial imaging, addresses a need that is not solved by the adaptive optics methods being used in astronomical imaging. Field-experiment verification of the TAFT concept requires instrumentation that is not available at Florida Atlantic University. The objective of this doctoral research program is thus to demonstrate, in the absence of full-scale experimentation, the feasibility of time-average Fourier telescopy through (a) the design, construction, and testing of small-scale laboratory instrumentation capable of exploring basic Fourier telescopy data-gathering operations, and (b) the development of MATLAB-based software capable of demonstrating the effect of kilometer-scale passage of laser beams through ground-level turbulence in a numerical simulation of TAFT.

  4. The development of water services and their interaction with water resources in European and Brazilian cities

    The extension and complexity of large cities creates "urban water" and a related issue: public water services, including public water supply, sewage collection and treatment, and storm water control, had previously become a policy sector separate from water resource allocation issues thanks to water transport and treatment technologies. Large metropolitan areas today cannot take nature for granted anymore, and they need to protect water resources, if only to reduce the long term cost of transporting and treating water. In this paper, we compare the historical development of water services in European and Brazilian metropolitan areas, placing the technological developments in their geographic, socio-economic and political contexts. Our frame is to follow the successive contributions of civil engineering, sanitary engineering, and environmental engineering: the "quantity of water" and civil engineering paradigm allowed to mobilise water in and out of the city, and up the hills or the floors; in the "water quality" and chemical/sanitary engineering paradigm, water treatment gave more freedom to cities to take water from rivers closer to them, but also to reduce sewer discharge impacts; lastly, the environmental engineering paradigm proposes to overcome the supply side perspective, by introducing demand side management, water conservation, water allocation flexibilisation, and an integrated approach to water services, water resources management, and land use policies.

    The study described in this article aimed at establishing a baseline assessment of the sanitary status of ice and guest rooms within Canadian hotels. Collectively, 54 hotel rooms belonging to six different national chains were sampled. High-contact surfaces (comforter, alarm clock, bedside lamp, TV remote, bathroom countertop, faucet, and toilet seat) were sampled using adenosine triphosphate (ATP) swabs and replicate organism detection and counting plates. ATP swab readings ranged from 2.12 to 4.42 log relative light units. Coliforms were recovered from 36% of surfaces with high prevalence being recovered from the comforter, TV remote, bathroom countertop, faucet, and toilet seat. Oxacillin-resistant bacteria were recovered from 19% of surfaces with 46% of isolates confirmed as methicillin-resistant Staphylococcus aureus. Two toxigenic Clostridium difficile isolates were recovered in the course of the study. Collectively, 24% of the ice samples harbored coliforms with a single sample testing positive for E. coli. The authors' study demonstrates that hotel rooms represent a potential source of community-acquired infections and the need for enhanced sanitation practices.

  7. Seasonal trends in vegetation and atmospheric concentrations of PAHs and PBDEs near a sanitary landfill

    NASA Astrophysics Data System (ADS)

    St-Amand, Annick D.; Mayer, Paul M.; Blais, Jules M.

    Spruce needle and atmospheric (gaseous and particulate-bound) concentrations were surveyed near a sanitary landfill from February 2004 to June 2005. The influence of several parameters such as temperature, relative humidity, wind speed and direction, as well as increased domestic heating during the winter was assessed. In general, polybrominated diphenyl ethers (PBDE) and polycyclic aromatic hydrocarbons (PAH) concentrations in spruce needles increased over time and decreased following snowmelt with a minimum coinciding with bud burst of deciduous trees. Atmospheric concentrations of PBDE and PAH, both particulate-bound and gaseous phase, were linked to daily weather events and thus showed more variability than those in spruce needles. Highest PAH concentrations were encountered during the winter, likely reflecting increased emission from heating homes. Pseudo Clausius-Clapeyron plots revealed higher PBDE gaseous concentrations with increasing temperature, but showed no correlation between PAH gaseous concentrations and temperature as this effect was obscured by seasonal emission patterns. Finally, air mass back trajectories and local wind directions revealed that particulate-bound PBDEs, along with both gaseous and particulate-bound PAHs were from local sources, whereas gaseous PBDEs were likely from distant sources.

  8. Post-remediation use of macrophytes as composting materials for sustainable management of a sanitary landfill.

    2017-04-03

    To increase the remediation ability and life expectancy of a leachate channel in a sanitary landfill, the plants used for remediation were composted as a post-remediation management technique. Phragmites australis or Typha angustifolia used for phytoremediation in a landfill leachate channel was harvested and used as a co-composting material with sewage sludge. The macrophyte compost was applied to the slope of a landfill on which plants were introduced for revegetation and to plants grown in pots to test for acute effects of the compost. The compost of the macrophytes successfully increased soil moisture and nutrient contents both on the landfill slope and in the soil of the pot experiment. Additionally, the rates of photosynthesis and the nutrient contents increased for plants grown in macrophyte compost. Thus, the revegetation or restoration management of the landfill would improve with the macrophyte compost used as a soil conditioner. The harvest of the macrophytes has the additional benefit of improving the remediation function of the leachate channel. Therefore, to sustainably manage both the leachate channel and the landfill, the composting of post-remediation macrophytes is an environmentally friendly and economically affordable method.

    The outsourcing informal home practices adopted in jewelry and fashion jewelry chain can cause toxic substance elimination in the effluents and raise a concern for its environmental impact. This study evaluates if this informal work alters the concentration of potentially toxic elements (PTEs: As, Cd, Cr total and Cr-VI, Cu, Hg, Ni, Pb, Sn, and Zn) in the sewage network. The sanitary sewage samples (n = 540) were collected in 15 manholes during two campaigns in three different areas of Limeira-SP, Brazil (industrial area, with informal work and without known industrial/informal activity). The sewage sludge (n = 12), raw (n = 12), and treated sewage (n = 12) were collected in two wastewater treatment plants (WWT: AS and TATU) operating with different treatment process. The PTE determination was performed by ICP-OES, direct mercury analysis, and UV-Vis spectroscopy. Cr-VI, Cu, Ni, and Zn were the only elements above the quantification limit. Four samples exceeded Cu or Zn values permitted to be discharged into sewage system; however, the concentration average was lower than that established by Brazilian legislation. A difference was found between values above and below the 75th percentile for campaign and total organic carbon values (p < 0.015). The AS-treated sewage presented low concentrations of Cu (p < 0.05), Zn (p = 0.02), and Ni (p = 0.01) compared to treated sewage from TATU. In the sludge samples, the Cu means exceeded the limits of the Brazilian legislation (1500 mg kg -1 ) and the Zn results were very close to the limits (2800 mg kg -1 ). The heterogeneity of the results can indicate the sporadic nature of the PTE's sanitary disposal. PTEs used in jewelry and fashion jewelry chain may precipitate on the sludge, where presented high concentrations of Cu and Zn which require controlled destination.

    The import substitution becomes one of the strategic tasks of national economy as a result of prolongation of economic sanctions concerning the Russian Federation of part of the USA, EU countries, Japan and number of other countries. It is not proper to be limited in import substitution only by goods because in conditions ofsanctions when access toforeign technologies is complicated Russia is needed to substitute foreign technologies by national designs in faster manner One of directions of effective import substitution is localization of production of laboratory equipment and consumables for clinical and sanitary microbiology on the territory ofthe Russian Federation and countries of Customs union. In Russia, in the field ofdiagnostic of dangerous and socially significant infections, all components for import substitution to implement gene diagnostic, immune diagnostic. bio-sensory and biochip approaches, isolation and storage of live microbial cultures, implementation of high-tech methods of diagnostic are available. At the same time, national diagnostic instrument-making industry for microbiology is factually absent. The few devices of national production more than on 50% consist of import components. The microbiological laboratories are to be equipped only with import devices of open type for applying national components. The most perspective national designs to be implemented are multiplex polimerase chain reaction test-systems and biochips on the basis of national plotters and readers. The modern development of diagnostic equipment and diagnostic instruments requires supplement of national collections of bacterial and viral pathogens and working-through of organizational schemes of supplying collections with strains. The presented data concerning justification of nomenclature of laboratory equipment and consumables permits to satisfy in fill scope the needs of clinical and sanitary microbiology in devices, growth mediums, consumables of national production

    2000-01-01

    In this study, characterization and anaerobic treatability of leachate from Komurcuoda Sanitary Landfill located on the Asian part of Istanbul were investigated. Time based fluctuations in characteristics of leachate were monitored for an 8 month period. Samples were taken from a 200 m3 holding tank located at the lowest elevation of the landfill. COD concentrations have ranged between 18,800 and 47,800 mg/l while BOD5 between 6820 and 38,500 mg/L. COD and BOD5 values were higher in summer and lower in winter due to dilution by precipitation. On the other hand, it was quite interesting that such a dilution effect was not observed for ammonia. The highest ammonia concentration, 2690 mg/L was in November 1998. BOD5/COD ratio was larger than 0.7 for most samples indicating high biodegradability, and acidic phase of decomposition in the landfill. For anaerobic treatability, three different reactors, namely an upflow anaerobic sludge bed reactor, an anaerobic upflow filter and a hybrid bed reactor, were used. The anaerobic reactors were operated for more than 230 days and were continuing operation when this paper was prepared. Organic loading was increased gradually from 1.3 kg COD/m3.day to 8.2 kg COD/m3.day while hydraulic retention time was reduced from 2.4 days to 2.0 days. All the reactors showed similar performances against organic loadings with efficiencies between 80% and 90%. However the reactors have experienced high ammonia concentrations several times throughout the experimental period, and showed different inhibition levels. Anaerobic filter was the least affected reactor while UASB was the most. Hybrid bed reactor has exhibited a similar performance to anaerobic filter although not to the same degree.

  16. How to model a negligible probability under the WTO sanitary and phytosanitary agreement?

    PubMed

    Powell, Mark R

    2013-06-01

    Since the 1997 EC--Hormones decision, World Trade Organization (WTO) Dispute Settlement Panels have wrestled with the question of what constitutes a negligible risk under the Sanitary and Phytosanitary Agreement. More recently, the 2010 WTO Australia--Apples Panel focused considerable attention on the appropriate quantitative model for a negligible probability in a risk assessment. The 2006 Australian Import Risk Analysis for Apples from New Zealand translated narrative probability statements into quantitative ranges. The uncertainty about a "negligible" probability was characterized as a uniform distribution with a minimum value of zero and a maximum value of 10(-6) . The Australia - Apples Panel found that the use of this distribution would tend to overestimate the likelihood of "negligible" events and indicated that a triangular distribution with a most probable value of zero and a maximum value of 10⁻⁶ would correct the bias. The Panel observed that the midpoint of the uniform distribution is 5 × 10⁻⁷ but did not consider that the triangular distribution has an expected value of 3.3 × 10⁻⁷. Therefore, if this triangular distribution is the appropriate correction, the magnitude of the bias found by the Panel appears modest. The Panel's detailed critique of the Australian risk assessment, and the conclusions of the WTO Appellate Body about the materiality of flaws found by the Panel, may have important implications for the standard of review for risk assessments under the WTO SPS Agreement. © 2012 Society for Risk Analysis.

    This article analyzes the construction of cancer as a sanitary problem and an object of scientific inquiry in Argentina in the first two decades of the twentieth century. It considers the acquisition and circulation of foreign knowledge on the subject, the context in which the first experimental developments arose, the institutional initiatives promoted by the medical profession and the way in which state authorities and civil society were enlisted to further these initiatives. There is a detailed examination of the process of creating the Instituto de Medicina Experimental, a center wholly devoted to the study and treatment of cancer, which was inaugurated in 1922, symbolically ending the first phase of constructing cancer as a problem in the country.

    Two operational-and-tactical factors had the main influence on organization of the surgical care rendered to the casualties on the Northern Caucasus: the fulminant and maneuverable nature of combat operations at the beginning of both armed conflicts and rather small territory of war theatre. The main special features of organization of surgical care to the casualties were the use of Medical Squads of Special Purpose in the combat conditions and maximal approximation of the specialized surgical care to the wounded by echelonment of medical units and wide use of helicopter evacuation. The structure of sanitary losses was characterized by the increase in the frequency of mechanical traumas, thermal and combined injuries, by the high share of the casualties with head injuries. Besides the number of seriously wounded and critical casualties has increased.

    Galicia autonomy received at the turn of the 60s and 70s of the XIX century contributed to the formation of organizational basis for activities in favour of improvement of health in the country, including the biggest city of Austrian partition--Lvov. In this city until the World War I outbreak intensive works concerning construction of sewage and water supply systems were performed, what beneficially affected the sanitary conditions in some districts. At the same time despite strenuous efforts, the attempts to provide cobbled permanent surfaces of the majority of roads were unsuccessful. Serious concerns were expressed in relation to living conditions of the Lvov working class. In the situation, the municipal self-governing health service, developed in 1872, with a few district sanitary physicians (7 in 1914) was not able to significantly decrease the incidence of infectious diseases and disease-related mortality rate, however some improvement in this issue was observed. Among the most dangerous diseases predominated tuberculosis, followed by scarlet fever, diphtheria, measles and whooping cough, typhoid fever and dysentery. At the beginning of the XX century the health service managed to eliminate smallpox due to implementation of annual vaccination of infants.

  1. Far-infrared Spectral Radiance Observations and Modeling of Arctic Cirrus: Preliminary Results From RHUBC

    NASA Astrophysics Data System (ADS)

    Humpage, Neil; Green, Paul D.; Harries, John E.

    2009-03-01

    Recent studies have highlighted the important contribution of the far-infrared (electromagnetic radiation with wavelengths greater than 12 μm) to the Earth's radiative energy budget. In a cloud-free atmosphere, a significant fraction of the Earth's cooling to space from the mid- and upper troposphere takes place via the water vapor pure rotational band between 17 and 33 μm. Cirrus clouds also play an important role in the Earth's outgoing longwave radiation. The effect of cirrus on far-infrared radiation is of particular interest, since the refractive index of ice depends strongly on wavelength in this spectral region. The scattering properties of ice crystals are directly related to the refractive index, so consequently the spectral signature of cirrus measured in the FIR is sensitive to the cloud microphysical properties [1, 2]. By examining radiances measured at wavelengths between the strong water vapor absorption lines in the FIR, the understanding of the relationship between cirrus microphysics and the radiative transfer of thermal energy through cirrus may be improved. Until recently, very few observations of FIR spectral radiances had been made. The Tropospheric Airborne Fourier Transform Spectrometer (TAFTS) was developed by Imperial College to address this lack of observational data. TAFTS observes both zenith and nadir radiances at 0.1 cm-1 resolution, between 80 and 600 cm-1. During February and March 2007, TAFTS was involved in RHUBC (the Radiative Heating in Under-explored Bands Campaign), an ARM funded field campaign based at the ACRF-North Slope of Alaska site near Barrow, situated at 71° latitude. Infrared zenith spectral observations were taken by both TAFTS and the AERI-ER (spectral range 400-3300 cm-1) from the ground during both cloud-free and cirrus conditions. A wide range of other instrumentation was also available at the site, including a micropulse lidar, 35 GHz radar and the University of Colorado/NOAA Ground-based Scanning Radiometer

    2015-03-01

    We evaluated the impact of the New York City restaurant letter-grading program on restaurant hygiene, food safety practices, and public awareness. We analyzed data from 43,448 restaurants inspected between 2007 and 2013 to measure changes in inspection score and violation citations since program launch in July 2010. We used binomial regression to assess probability of scoring 0 to 13 points (A-range score). Two population-based random-digit-dial telephone surveys assessed public perceptions of the program. After we controlled for repeated restaurant observations, season of inspection, and chain restaurant status, the probability of scoring 0 to 13 points on an unannounced inspection increased 35% (95% confidence interval [CI]=31%, 40%) 3 years after compared with 3 years before grading. There were notable improvements in compliance with some specific requirements, including having a certified kitchen manager on site and being pest-free. More than 91% (95% CI=88%, 94%) of New Yorkers approved of the program and 88% (95% CI=85%, 92%) considered grades in dining decisions in 2012. Restaurant letter grading in New York City has resulted in improved sanitary conditions on unannounced inspection, suggesting that the program is an effective regulatory tool.

    The electro-Fenton oxidation of a concentrate from reverse osmosis of a sanitary landfill leachate, with an initial chemical oxygen demand (COD) of 42 g L -1 , was carried out using a carbon-felt cathode and a boron doped diamond anode. The influence of the applied current intensity, initial pH and dissolved iron initial concentration on the electro-Fenton process was assessed. For the experimental conditions used, results showed that the initial pH is the parameter that more strongly influences the current efficiency of the electro-Fenton process, being this influence more pronounced on the oxidation rate than on the mineralization rate of the organic matter. The increase in iron initial concentration was found to be detrimental, since the natural amount of iron present in the effluent, 73 mg L -1 of total iron and 61 mg L -1 of dissolved iron, was sufficient to ensure the electro-Fenton process at the applied intensities - 0.2-1.4 A. For the more favourable conditions studied, initial pH of 3 and natural iron concentration, it was found an increase in the organic load and nitrogen removals with the applied current intensity. For the highest current intensity applied, a COD removal of 16.7 g L -1 was achieved after 8-h experiments. Copyright © 2017 Elsevier Ltd. All rights reserved.

    A worst-case simulation of the mass-balance for metals in the waste deposited during 1 year and the levels of cadmium (Cd), lead (Pb), mercury (Hg), chromium (Cr) and iron (Fe) in the leachate was calculated for four sanitary landfills in Western Norway. Estimates of the levels of metal content in mixed municipal solid waste (MSW) were found by using recent literature values calculated in a mass-balance study at a Norwegian waste incinerator plant. Leachate from the landfills were sampled and analyzed monthly during 1 year, and from these measurements the total annual discharge of the selected metals through the leachate was determined. The levels of the measured heavy metals in the leachate were low. For Cd less than 0.06%, for Pb less than 0.01% and for Hg less than 0.02% of the estimated year's deposited mass of metals were leached from the landfills during the year of investigation. The high retention of these metals are most likely due to sulfide precipitation, but also due to the immobile condition of the metals in their original deposited solid state (plastics, ceramics, etc.). The percentage of Cr leached was relatively higher, but less than 1.0% per year. The mass balance of Fe suggests that this element is more mobile under the prevailing conditions. The percentage of Fe leached varied and was estimated to be between 1.9% and 18%. The present study clearly supports the theory that MSW only to a small extent will lead to discharge of metals if deposited at well-constructed sanitary landfills with top layers.

    Analysis of national health insurance accounts in the Democratic Republic of Congo (DRC) clearly shows the importance of international sanitary aid, particularlyfor thefunding ofgeneral referral hospitals, the management of inpatients with AIDS, administration of health zones andfunding of preventive care providers. It The targeted changes described in this article could possibly optimize the efficiency ofinternational aidfor the DRC population, mainly for disorders considered to be a health care priority (i.e. malaria, AIDS, tuberculosis) as well as in the fight against malnutrition. Recommendations target the implementation of procedures for control offood chain security, changes in lifestyle and dietary habits of the population but also comprise extensive restructuring of the health care administration. A dramatic change of the structure in charge of drug distribution as well as eradication of the transfer of part of public health structure income to public health administrative personnel could result in the allocation of significantfunds to thefight against the most important diseases. Better collaboration between the various departments in charge of health care professional training, together with enhanced responsibility of health care personnel is essential. Independent and respected non-governmental organizations should be involved in an audit process, targeting all aspects of the current DRC health system. Eventually, in an equal opportunity perspective, taking into consideration the very high degree of poverty ofDRC inhabitants, implementation of health insurance programmes, use ofgeneric drugs and generalization ofmicro-credit initiatives should also be implemented.

    Objectives. We evaluated the impact of the New York City restaurant letter-grading program on restaurant hygiene, food safety practices, and public awareness. Methods. We analyzed data from 43 448 restaurants inspected between 2007 and 2013 to measure changes in inspection score and violation citations since program launch in July 2010. We used binomial regression to assess probability of scoring 0 to 13 points (A-range score). Two population-based random-digit-dial telephone surveys assessed public perceptions of the program. Results. After we controlled for repeated restaurant observations, season of inspection, and chain restaurant status, the probability of scoring 0 to 13 points on an unannounced inspection increased 35% (95% confidence interval [CI] = 31%, 40%) 3 years after compared with 3 years before grading. There were notable improvements in compliance with some specific requirements, including having a certified kitchen manager on site and being pest-free. More than 91% (95% CI = 88%, 94%) of New Yorkers approved of the program and 88% (95% CI = 85%, 92%) considered grades in dining decisions in 2012. Conclusions. Restaurant letter grading in New York City has resulted in improved sanitary conditions on unannounced inspection, suggesting that the program is an effective regulatory tool. PMID:25602861

  19. Seismic analysis of the frame structure reformed by cutting off column and jacking based on stiffness ratio

    NASA Astrophysics Data System (ADS)

    Zhao, J. K.; Xu, X. S.

    2017-11-01

    The cutting off column and jacking technology is a method for increasing story height, which has been widely used and paid much attention in engineering. The stiffness will be changed after the process of cutting off column and jacking, which directly affects the overall seismic performance. It is usually necessary to take seismic strengthening measures to enhance the stiffness. A five story frame structure jacking project in Jinan High-tech Zone was taken as an example, and three finite element models were established which contains the frame model before lifting, after lifting and after strengthening. Based on the stiffness, the dynamic time-history analysis was carried out to research its seismic performance under the EL-Centro seismic wave, the Taft seismic wave and the Tianjin artificial seismic wave. The research can provide some guidance for the design and construction of the entire jack lifting structure.

  6. Engineering ethics beyond engineers' ethics.

    PubMed

    Basart, Josep M; Serra, Montse

    2013-03-01

    Engineering ethics is usually focused on engineers' ethics, engineers acting as individuals. Certainly, these professionals play a central role in the matter, but engineers are not a singularity inside engineering; they exist and operate as a part of a complex network of mutual relationships between many other people, organizations and groups. When engineering ethics and engineers' ethics are taken as one and the same thing the paradigm of the ethical engineer which prevails is that of the heroic engineer, a certain model of the ideal engineer: someone both quite individualistic and strong enough to deal with all the moral challenges that could arise. We argue that this is not the best approach, at least today in our interrelated world. We have achieved a high degree of independence from nature by means of technology. In exchange for this autonomy we have become increasingly tied up with very complex systems to which we constantly delegate new tasks and powers. Concerns about safety keep growing everywhere due to the fact that now we have a sensitive awareness of the huge amount of power we are both consuming and deploying, thus, new forms of dialogue and consensus have to be incorporated at different levels, in different forums and at different times. Within these democratic channels of participation not just the needs and interests, but also the responsibilities and mutual commitments of all parties should be taken into account.

  9. Exo-Skeletal Engine: Novel Engine Concept

    NASA Technical Reports Server (NTRS)

    Chamis, Cristos C.; Blankson, Isaiah M.

    2004-01-01

    The exo-skeletal engine concept represents a new radical engine technology with the potential to substantially revolutionize engine design. It is an all-composite drum-rotor engine in which conventionally heavy shafts and discs are eliminated and are replaced by rotating casings that support the blades in spanwise compression. Thus the rotating blades are in compression rather than tension. The resulting open channel at the engine centerline has immense potential for jet noise reduction and can also accommodate an inner combined-cycle thruster such as a ramjet. The exo-skeletal engine is described in some detail with respect to geometry, components, and potential benefits. Initial evaluations and results for drum rotors, bearings, and weights are summarized. Component configuration, assembly plan, and potential fabrication processes are also identified. A finite element model of the assembled engine and its major components is described. Preliminary results obtained thus far show at least a 30-percent reduction of engine weight and about a 10-dB noise reduction, compared with a baseline conventional high-bypass-ratio engine. Potential benefits in all aspects of this engine technology are identified and tabulated. Quantitative assessments of potential benefits are in progress.

    2005-01-01

    Systems Engineering is fundamental to good engineering, which in turn depends on the integration and application of engineering lessons learned. Thus, good Systems Engineering also depends on systems engineering lessons learned from within the aerospace industry being documented and applied. About ten percent of the engineering lessons learned documented in the NASA Lessons Learned Information System are directly related to Systems Engineering. A key issue associated with lessons learned datasets is the communication and incorporation of this information into engineering processes. As part of the NASA Technical Standards Program activities, engineering lessons learned datasets have been identified from a number of sources. These are being searched and screened for those having a relation to Technical Standards. This paper will address some of these Systems Engineering Lessons Learned and how they are being related to Technical Standards within the NASA Technical Standards Program, including linking to the Agency's Interactive Engineering Discipline Training Courses and the life cycle for a flight vehicle development program.

  13. Humanitarian engineering in the engineering curriculum

    NASA Astrophysics Data System (ADS)

    Vandersteen, Jonathan Daniel James

    There are many opportunities to use engineering skills to improve the conditions for marginalized communities, but our current engineering education praxis does not instruct on how engineering can be a force for human development. In a time of great inequality and exploitation, the desire to work with the impoverished is prevalent, and it has been proposed to adjust the engineering curriculum to include a larger focus on human needs. This proposed curriculum philosophy is called humanitarian engineering. Professional engineers have played an important role in the modern history of power, wealth, economic development, war, and industrialization; they have also contributed to infrastructure, sanitation, and energy sources necessary to meet human need. Engineers are currently at an important point in time when they must look back on their history in order to be more clear about how to move forward. The changing role of the engineer in history puts into context the call for a more balanced, community-centred engineering curriculum. Qualitative, phenomenographic research was conducted in order to understand the need, opportunity, benefits, and limitations of a proposed humanitarian engineering curriculum. The potential role of the engineer in marginalized communities and details regarding what a humanitarian engineering program could look like were also investigated. Thirty-two semi-structured research interviews were conducted in Canada and Ghana in order to collect a pool of understanding before a phenomenographic analysis resulted in five distinct outcome spaces. The data suggests that an effective curriculum design will include teaching technical skills in conjunction with instructing about issues of social justice, social location, cultural awareness, root causes of marginalization, a broader understanding of technology, and unlearning many elements about the role of the engineer and the dominant economic/political ideology.

    2012-05-01

    The onset of menstruation is one of the most important physiological changes occurring among girls during the adolescent years. Menstruation heralds the onset of physiological maturity in girls. It becomes the part and parcel of their lives until menopause. Apart from personal importance, this phenomenon also has social significance. In India, menstruation is surrounded by myths and misconceptions with a long list of "do's" and "don'ts" for women. Hygiene-related practices of women during menstruation are of considerable importance, as it may increase vulnerability to Reproductive Tract Infections (RTI's). Poor menstrual hygiene is one of the major reasons for the high prevalence of RTIs in the country and contributes significantly to female morbidity. Most of the adolescent girls in villages use rags and old clothes during menstruation, increasing susceptibility to RTI's. Adolescents constitute one-fifths of India's population and yet their sexual health needs remain largely unaddressed in the national welfare programs. Poor menstrual hygiene in developing countries has been an insufficiently acknowledged problem. In June 2010, the Government of India proposed a new scheme towards menstrual hygiene by a provision of subsidized sanitary napkins to rural adolescent girls. But there are various other issues like awareness, availability and quality of napkins, regular supply, privacy, water supply, disposal of napkins, reproductive health education and family support which needs simultaneous attention for promotion of menstrual hygiene. The current article looks at the issue of menstrual hygiene not only from the health point of view, but also considers social and human rights values attached to it.

    In 1998, a prototype 300 kHz, side-looking Acoustic Doppler Current Profiler (ADCP) was deployed in the Chicago Sanitary and Ship Canal (CSSC) at Romeoville, Illinois. Additionally, two upward-looking ADCP's were deployed in the same acoustic path as the side-looking ADCP and in the reach defined by the upstream and downstream acoustic velocity meter (AVM) paths. All three ADCP's were synchronized to the AVM clock at the gaging station so that data were sampled simultaneously. The three ADCP's were deployed for six weeks measuring flow velocities from 0.0 to 2.5 ft/s. Velocities measured by each ADCP were compared to AVM path velocities and to velocities measured by the other ADCP's.

    2014-11-19

    Treatment of lateral fractures of the clavicle is challenging and has been controversially discussed for a long time due to high non-union rates in non-operative treatment and high complication rates in surgical treatment. Acromioclavicular joint instability due to the injury of the closely neighbored coraco-clavicular ligaments can result in a cranialization of the medial clavicle shaft. A recently developed implant showed a promising functional outcome in a small collective of patients. In this prospective study, 20 patients with a mean age of 40.7 ± 11.3 years with a dislocated fracture of the lateral clavicle (Jäger&Breitner I-III, Neer I-III) were enrolled. All patients were surgically treated using the locking compression plate (LCP) for the superior anterior clavicle (Synthes®). Functional outcome was recorded using the Munich Shoulder Questionnaire (MSQ) allowing for qualitative self-assessment of the Shoulder Pain and Disability Index (SPADI), of the Disability of the Arm, Shoulder and Hand (DASH) score and of the Constant Score. Acromioclavicular joint stability was evaluated using the Taft-Score. The mean follow-up was 14.2 ± 4.0 months. The mean MSQ was 87.0 ± 7.4 points, the mean SPADI 91.1 ± 11.3 points, the mean DASH score 7.6 ± 7.3 points and the mean normative age- and sex-specific Constant Score 85.6 ± 8.0 points. The mean Taft Score resulted in 10.7 ± 1.0 points. The mean Taft Score in lateral clavicular fractures with fracture gap between the coracoclavicular ligaments in combination with a rupture of the conoid ligament (J&B II a, Neer II B; n =11) was with 10.3 ± 0.9 points significantly lower than the mean Taft Score of all other types of lateral clavicle fractures (J&B I, II b, III; n =9) which resulted in 11.3 ± 0.9 points (p<0.05). The Synthes® LCP superior anterior clavicle plate allows for a safe stabilization and good functional outcome with high patient satisfaction in fractures of the lateral clavicle. However, in

    1977-01-01

    A digital computer simulation of a mixed flow, twin spool turbofan engine was assembled to evaluate and improve the dynamic characteristics of the engine simulation to disturbance frequencies of at least 100 Hz. One dimensional forms of the dynamic mass, momentum and energy equations were used to model the engine. A TF30 engine was simulated so that dynamic characteristics could be evaluated against results obtained from testing of the TF30 engine at the NASA Lewis Research Center. Dynamic characteristics of the engine simulation were improved by modifying the compression system model. Modifications to the compression system model were established by investigating the influence of size and number of finite dynamic elements. Based on the results of this program, high frequency engine simulations using finite dynamic elements can be assembled so that the engine dynamic configuration is optimum with respect to dynamic characteristics and computer execution time. Resizing of the compression systems finite elements improved the dynamic characteristics of the engine simulation but showed that additional refinements are required to obtain close agreement simulation and actual engine dynamic characteristics.

    Sander, Erik J.; Gosdin, Dennis R.

    1992-01-01

    Engineers regularly analyze SSME ground test and flight data with respect to engine systems performance. Recently, a redesigned SSME powerhead was introduced to engine-level testing in part to increase engine operational margins through optimization of the engine internal environment. This paper presents an overview of the MSFC personnel engine systems analysis results and conclusions reached from initial engine level testing of the redesigned powerhead, and further redesigns incorporated to eliminate accelerated main injector baffle and main combustion chamber hot gas wall degradation. The conclusions are drawn from instrumented engine ground test data and hardware integrity analysis reports and address initial engine test results with respect to the apparent design change effects on engine system and component operation.

    A notation is described for depicting the relationships between multiple, contemporaneous systems engineering efforts undertaken within a multi-layer system-of-systems hierarchy. We combined the concepts of remoteness of activity from the end customer, depiction of activity on a timeline, and data flow to create a new kind of diagram which we call a "Layered Vee Diagram." This notation is an advance over previous notations because it is able to be simultaneously precise about activity, level of granularity, product exchanges, and timing; these advances provide systems engineering managers a significantly improved ability to express and understand the relationships between many systems engineering efforts. Using the new notation, we obtain a key insight into the relationship between project duration and the strategy selected for chaining the systems engineering effort between layers, as well as insights into the costs, opportunities, and risks associated with alternate chaining strategies.

    2015-11-01

    Metabolic engineering has expanded from a focus on designs requiring a small number of genetic modifications to increasingly complex designs driven by advances in genome-scale engineering technologies. Metabolic engineering has been generally defined by the use of iterative cycles of rational genome modifications, strain analysis and characterization, and a synthesis step that fuels additional hypothesis generation. This cycle mirrors the Design-Build-Test-Learn cycle followed throughout various engineering fields that has recently become a defining aspect of synthetic biology. This review will attempt to summarize recent genome-scale design, build, test, and learn technologies and relate their use to a range of metabolic engineering applications.

  6. Activist engineering: changing engineering practice by deploying praxis.

    PubMed

    Karwat, Darshan M A; Eagle, Walter E; Wooldridge, Margaret S; Princen, Thomas E

    2015-02-01

    In this paper, we reflect on current notions of engineering practice by examining some of the motives for engineered solutions to the problem of climate change. We draw on fields such as science and technology studies, the philosophy of technology, and environmental ethics to highlight how dominant notions of apoliticism and ahistoricity are ingrained in contemporary engineering practice. We argue that a solely technological response to climate change does not question the social, political, and cultural tenet of infinite material growth, one of the root causes of climate change. In response to the contemporary engineering practice, we define an activist engineer as someone who not only can provide specific engineered solutions, but who also steps back from their work and tackles the question, What is the real problem and does this problem "require" an engineering intervention? Solving complex problems like climate change requires radical cultural change, and a significant obstacle is educating engineers about how to conceive of and create "authentic alternatives," that is, solutions that differ from the paradigm of "technologically improving" our way out of problems. As a means to realize radically new solutions, we investigate how engineers might (re)deploy the concept of praxis, which raises awareness in engineers of the inherent politics of technological design. Praxis empowers engineers with a more comprehensive understanding of problems, and thus transforms technologies, when appropriate, into more socially just and ecologically sensitive interventions. Most importantly, praxis also raises a radical alternative rarely considered-not "engineering a solution." Activist engineering offers a contrasting method to contemporary engineering practice and leads toward social justice and ecological protection through problem solving by asking not, How will we technologize our way out of the problems we face? but instead, What really needs to be done?

  7. Using Collaborative Engineering to Inform Collaboration Engineering

    Collaboration is a critical competency for modern organizations as they struggle to compete in an increasingly complex, global environment. A large body of research on collaboration in the workplace focuses both on teams, investigating how groups use teamwork to perform their task work, and on the use of information systems to support team processes ("collaboration engineering"). This research essay presents collaboration from an engineering perspective ("collaborative engineering"). It uses examples from professional and student engineering teams to illustrate key differences in collaborative versus collaboration engineering and investigates how challenges in the former can inform opportunities for the latter.

    The potential for hepatitis B and C virus (HBV/HCV) transmission in nail salons and barbershops has been reported, but a systematic review has not been conducted. These businesses are regulated by state cosmetology or barbering boards, but adequacy of sanitary requirements has not been evaluated. To conduct literature review to assess risk for HBV/HCV transmission in nail salons and barbershops and to evaluate sanitary requirements in HBV/HCV prevention in these businesses in 50 states and District of Columbia. Several search engines were used for literature search. Studies that quantified risks associated with manicuring, pedicuring, or barbering were included. State requirements for disinfection and sterilization were reviewed and evaluated. For literature review, odds ratios, 95% confidence intervals, and confounding adjustment were extracted and evaluated. For regulation review, requirements for disinfection or sterilization for multiuse items in nail salons and barbershops were assessed according to the US federal guidelines. Forty-six studies were identified and 36 were included in this study. Overall, the results were not consistent on risk for HBV/HCV transmission in nail salons and barbershops. For sanitary requirements, disinfection with an Environmental Protection Agency-registered disinfectant is required in 39 states for nail salons and in 26 states for barbershops. Sterilization was described in 15 states for nail salons and in 11 states for barbershops, but the majority of these states listed it as an optional approach. Sanitary requirements are consistent in states where 1 board regulates both businesses but are substantially discrepant in states with separate boards. Current literature cannot confirm or exclude the risk for HBV/HCV transmission in nail salons and barbershops. Existing sanitary requirements are adequate in the majority of states, but compliance is needed to prevent HBV/HCV transmission in these businesses.

  18. Women and the Engineering Profession: the Stereotypical Engineer

    NASA Astrophysics Data System (ADS)

    Cory, Suzanne N.; Rezaie, Bahman

    The paucity of female engineers has been a problem for years, and most universities suffer from a lack of women majoring in engineering. It is possible that the stereotypical image or perceived gender of engineers may deter young women from considering a career in the field. In order to determine whether 1st-year college students held perceptions regarding personality traits and probable gender of an engineer, a survey was developed based on the Personality Factor (PF) questionnaire originally developed by Cattell (1943). Results indicate that personality traits most often associated with engineers were primarily masculine. Also, engineers were most often expected to be male, especially by the females in this study. Perceived personality traits and the probable gender of engineers were compared to those of 5 other professions: accountants, lawyers, physicians, insurance broker/agents, and computer and information systems specialists. Several differences in perceived personality traits were found. In addition, engineers were perceived as more likely to be male than members of all of the other occupations studied except computer and information systems specialists. Possible approaches to begin altering young women's perceptions of personality traits and the probably gender of a stereotypical engineer are discussed.

    2018-05-01

    Ongoing efforts to broaden the participation of women and people of colour in engineering degree programmes and careers have had limited success. This paper describes a different approach to broadening participation that seeks to work with all students and develop inclusive engineering identities. Researchers worked with the instructors of two first-year engineering courses to integrate curriculum activities designed to promote the formation of engineering identities and build an appreciation for how diversity and inclusion strengthen engineering practice. Multilevel modelling results indicated positive effects of the intervention on appreciation for diversity but no effects on engineering identity, and qualitative results indicated students learned the most about diversity not through one of the intervention activities, but through team projects in the courses. We also describe lessons learned in how to teach engineering students about diversity in ways that are relevant to engineering.

    2016-01-01

    Health concerns unique to women are growing with the large number of women venturing into different trades that expose them to hot working environments and inadequate sanitation facilities, common in many Indian workplaces. The study was carried out to investigate the health implications of exposures to hot work environments and inadequate sanitation facilities at their workplaces for women workers. A cross-sectional study was conducted with 312 women workers in three occupational sectors in 2014-2015. Quantitative data on heat exposures and physiological heat strain indicators such as core body temperature (CBT), sweat rate (SwR), and urine specific gravity (USG) were collected. A structured questionnaire captured workers perceptions about health impacts of heat stress and inadequate sanitary facilities at the workplace. Workplace heat exposures exceeded the threshold limit value for safe manual work for 71% women (Avg. wet bulb globe temperature=30°C±2.3°C) during the study period. Eighty-seven percent of the 200 women who had inadequate/no toilets at their workplaces reported experiencing genitourinary problems periodically. Above normal CBT, SwR, and USG in about 10% women workers indicated heat strain and moderate dehydration that corroborated well with their perceptions. Observed significant associations between high-heat exposures and SwR (t=-2.3879, p=0.0192), inadequate toilet facilities and self-reported adverse heat-related health symptoms (χ (2)=4.03, p=0.0444), and prevalence of genitourinary issues (χ (2)=42.92, p=0.0005×10(-7)) reemphasize that heat is a risk and lack of sanitation facilities is a major health concern for women workers. The preliminary evidence suggests that health of women workers is at risk due to occupational heat exposures and inadequate sanitation facilities at many Indian workplaces. Intervention through strong labor policies with gender sensitivity is the need of the hour to empower women, avert further health risks, and

    Engineering changes make an impact on different process chains in and outside the company, and lead to most error costs and time shifts. In fact, 30 to 50 per cent of development costs result from technical changes. Controlling engineering change processes can help us to avoid errors and risks, and contribute to cost optimization and a shorter time to market. This paper presents a method framework for controlling engineering changes at mechanical engineering companies. The developed classification of engineering changes and accordingly process requirements build the basis for the method framework. The developed method framework comprises two main areas: special data objects managed in different engineering IT tools and process framework. Objects from both areas are building blocks that can be selected to the overall business process based on the engineering process type and change classification. The process framework contains steps for the creation of change objects (both for overall change and for parts), change implementation, and release. Companies can select singleprocess building blocks from the framework, depending on the product development process and change impact. The developed change framework has been implemented at a division (10,000 employees) of a big German mechanical engineering company.

    The Chicago Sanitary and Ship Canal (CSSC) links the Great Lakes to the Mississippi River starting in downtown Chicago. In addition to storm water, the CSSC receives water from Chicago's wastewater treatment plants (WWTP). Such effluents are known to be sources of organic pollutants to water and sediment. Therefore in 2013, we collected 10 sediment samples from the CSSC and measured the concentrations of polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), brominated flame retardants, and organophosphate esters (OPEs). Geometric mean concentrations of the summed concentrations of 16 PAHs ranged from 11,000 to 420,000 ng/g dw, with the highest concentrations located at each end of the canal. Total PCB concentrations had a geometric mean of 1,400 ± 500 ng/g dw. Brominated flame retardants were separated into two groups: polybrominated diphenyl ethers (PBDEs) and non-PBDEs. Concentrations of PBDEs and those of the non-PBDE flame retardants had a geometric average of 83 ± 19 and 7.0 ± 5.8 ng/g dw, respectively. The summed concentrations of 8 OPEs ranged from 470 to 2,800 ng/g dw, with the highest concentration detected at a site located downstream of the Stickney water reclamation plant. Using ANOVA results, some hypotheses on sources to the CSSC could be formulated: downtown Chicago is probably a source of PAHs, the Cal-Sag Channel may be a source of PCBs, and neither the WWTP nor the Cal-Sag Channel seem to be significant sources of brominated flame retardants or OPEs.

    Iodine is an essential trace element implicated in synthesis of thyroid hormones. Iodine requirements vary throughout life. This iodine requirement is increased during pregnancy and breastfeeding. In a previous study carried out by our group in 2008, we detected an iodine-deficient area in the province of Huelva, specially in district Sierra de Huelva-Andévalo by means of neonatal TSH determinations. To reinforce the iodine supplementation campaign and its impact on their newborns in order to assess nutrition iodine status in pregnant women using questionnaire and ioduria determination. This study has been jointly carried out by Congenital Hypothyroidism Unit of the Clinical Biochemistry Department of the Virgen Macarena University Hospital (Seville) and the Gynecology and Clinical Analysis Unit of the Río Tinto Hospital (Huelva) during two years. We studied 313 pregnant women. All of them filled out a personal questionnaire to know the iodine nutritional status in their area. Ioduria was determinated by high-resolution liquid chromatography. Data from pregnant women and results of the studied variables were analyzed with SPSS v13.0. Pregnant women from the sanitary district Sierra de Huelva-Andévalo present a median for ioduria which corresponds to an insufficient iodine intake according to the WHO classification. The questionnaires suggest that this iodine deficiency is consequence of an insufficient iodine intake and a low adherence to the treatment.

  1. First-year engineering students' views of the nature of engineering

    NASA Astrophysics Data System (ADS)

    Karatas, Faik O.

    The changing nature of engineering problems and new challenges that result from globalization and new ways of doing business have triggered calls for a revolutionary shift in engineering education. To respond to these challenges, the engineering education paradigm has been revised by adding more design and humanities/social sciences components to it. Philosophy, sociology, and history of engineering are more often cited as a major part of engineering education in this movement. Research on the nature of engineering (NOE), which is derived from philosophy, sociology, and the history of engineering, could have as much potential impact on engineering education as research on the nature of science (NOS) has had on science education. Thus, it is surprising that there has been no noteworthy research on this topic. The purpose of this study is to describe and determine first-year engineering students' views of the NOE and how these students differentiate engineering from science. In this research, an open-ended Views of the Nature of Engineering questionnaire (VNOE) was employed to collect baseline data. Semi-structured interviews based on the VNOE questionnaire were conducted with the second cohort of the participants. Data analysis was guided by a traditional phenomenographic approach, which is a branch of the hermeneutic tradition, coupled to constant comparison technique. The results of this study indicated that the participants' overall views of the nature of engineering were not ill-developed, but rather unarticulated. Moreover, the relationship between engineering and science was considered unidirectional rather than bidirectional. The results of this study could be used to inform engineering educators, first-year engineering coordinators, and policy makers as well as serving as the base for further research and potential implications for future first-year and K-12 engineering education.

    The paper describes an engineering method scenario which categorizes the various activities and tasks into blocks seen as subjects which consume and produce data and information. These methods, tools, and associated utilities interact with other engineering tools by exchanging information in such a way that a relationship between customers and suppliers of engineering data is established clearly, while data exchange consistency is maintained throughout the design process. The events and data transactions are presented in the form of flowcharts in which data transactions represent the connection between the various bricks, which in turn represent the engineering activities developed for the particular task required in the concurrent engineering environment.

    The Enviro-chem site is a former waste recovery/reclamation/brokerage facility in Boone County, Indiana. Adjacent to the site is another Superfund site, the Northside Sanitary Landfill (NSL) which, prior to the Record of Decision (ROD) amendment, was to be remediated in a combined remedy for both sites. Land use in the area is agricultural and residential to the north and west. In May 1982, the State ordered Enviro-Chem to close and environmentally secure the site because it failed to reduce hazardous waste inventories. Subsequently, two emergency removal actions were conducted to remove the major sources of contamination. The ROD amends themore » 1987 ROD and provides a comprehensive site remedy for the Enviro-Chem site addressing source control instead of ground water remediation. The primary contaminants of concern affecting the soil are VOCs including PCE, TCE, toluene; and other organics including phenols. The amended remedial action for the site includes treating contaminated soil onsite using soil vapor extraction with a granulated activated carbon system to control the extracted vapor and implementing a contingent remedy for a subsurface ground water collection and treatment system.« less

    2017-01-01

    In December 2009, during a piscicide treatment targeting the invasive Asian carp in the Chicago Sanitary and Ship Canal, Rhodamine WT dye was released to track and document the transport and dispersion of the piscicide. In this study, two modeling approaches are presented to reproduce the advection and dispersion of the dye tracer (and piscicide), a one-dimensional analytical solution and a three-dimensional numerical model. The two approaches were compared with field measurements of concentration and their applicability is discussed. Acoustic Doppler current profiler measurements were used to estimate the longitudinal dispersion coefficients at ten cross sections, which were taken as reference for calibrating the longitudinal dispersion coefficient in the one-dimensional analytical solution. While the analytical solution is fast, relatively simple, and can fairly accurately predict the core of the observed concentration time series at points downstream, it does not capture the tail of the breakthrough curves. These tails are well reproduced by the three-dimensional model, because it accounts for the effects of dead zones and a power plant which withdraws nearly 80 % of the water from the canal for cooling purposes before returning it back to the canal.

    Questionnaire to ask “mention three names of scientists you know” and “three names of engineers you know” was conducted and the answers from 140 adults were analyzed. The results indicated that the image of scientists is represented by Nobel laureates and that of engineers by great inventors like Thomas Edison and industry founders like Soichiro Honda. In order to reveal the image of engineers among young generation, questionnaire was conducted for pupils in middle and high schools. Answers from 1,230 pupils were analyzed and 226 names mentioned as engineers were classified. White votes reached 60%. Engineers who are neither big inventors nor company founders collected less than 1% of named votes. Engineers are astonishingly invisible from young generation. Countermeasures are proposed.

  12. High Reliability Engine Control Demonstrated for Aircraft Engines

    NASA Technical Reports Server (NTRS)

    Guo, Ten-Huei

    1999-01-01

    For a dual redundant-control system, which is typical for short-haul aircraft, if a failure is detected in a control sensor, the engine control is transferred to a safety mode and an advisory is issued for immediate maintenance action to replace the failed sensor. The safety mode typically results in severely degraded engine performance. The goal of the High Reliability Engine Control (HREC) program was to demonstrate that the neural-network-based sensor validation technology can safely operate an engine by using the nominal closed-loop control during and after sensor failures. With this technology, engine performance could be maintained, and the sensor could be replaced as a conveniently scheduled maintenance action.

    Energy independence and fuel savings are hallmarks of the nation’s energy strategy. The advancement of natural gas reciprocating engine power generation technology is critical to the nation’s future. A new engine platform that meets the efficiency, emissions, fuel flexibility, cost and reliability/maintainability targets will enable American manufacturers to have highly competitive products that provide substantial environmental and economic benefits in the US and in international markets. Along with Cummins and Waukesha, Caterpillar participated in a multiyear cooperative agreement with the Department of Energy to create a 50% efficiency natural gas powered reciprocating engine system with a 95% reduction in NOxmore » emissions by the year 2013. This platform developed under this agreement will be a significant contributor to the US energy strategy and will enable gas engine technology to remain a highly competitive choice, meeting customer cost of electricity targets, and regulatory environmental standard. Engine development under the Advanced Reciprocating Engine System (ARES) program was divided into phases, with the ultimate goal being approached in a series of incremental steps. This incremental approach would promote the commercialization of ARES technologies as soon as they emerged from development and would provide a technical and commercial foundation of later-developing technologies. Demonstrations of the Phase I and Phase II technology were completed in 2004 and 2008, respectively. Program tasks in Phase III included component and system development and testing from 2009-2012. Two advanced ignition technology evaluations were investigated under the ARES program: laser ignition and distributed ignition (DIGN). In collaboration with Colorado State University (CSU), a laser ignition system was developed to provide ignition at lean burn and high boost conditions. Much work has been performed in Caterpillar’s DIGN program under the ARES program. This

    1985-01-01

    By 1990, sanitary sewers in Nassau County Sewage Disposal Districts 2 and 3 and Suffolk County Southwest Sewer District will discharge to the ocean 140 cu ft of water per second that would otherwise be returned to the groundwater system through septic tanks and similar systems. To evaluate the effects of this loss on groundwater levels and streamflow, the U.S. Geological Survey developed a groundwater flow model that couples a fine-scale subregional model to a regional model of a larger scale. The regional model generates flux boundary conditions for the subregional model, and the subregional model provides detail in the area of concern. Results indicate that the water table will decline by as much as 90% from conditions in the early 1970's. This report is one of a three-part series describing the predicted hydrologic effects of sewers in southern Nassau and southwestern Suffolk Counties. (USGS)

    In Task D.6 of the Advanced Engine Study, three primary subtasks were accomplished: (1) design of parametric data; (2) engine requirement variation studies; and (3) vehicle study/engine study coordination. Parametric data were generated for vacuum thrusts ranging from 7500 lbf to 50,000 lbf, nozzle expansion ratios from 600 to 1200, and engine mixture ratios from 5:1 to 7:1. Failure Modes and Effects Analysis (FMEA) was used as a departure point for these parametric analyses. These data are intended to assist in definition and trade studies. In the Engine Requirements Variation Studies, the individual effects of increasing the throttling ratio from 10:1 to 20:1 and requiring the engine to operate at a maximum mixture ratio of 12:1 were determined. Off design engine balances were generated at these extreme conditions and individual component operating requirements analyzed in detail. Potential problems were identified and possible solutions generated. In the Vehicle Study/Engine Study coordination subtask, vehicle contractor support was provided as needed, addressing a variety of issues uncovered during vehicle trade studies. This support was primarily provided during Technical Interchange Meetings (TIM) in which Space Exploration Initiative (SEI) studies were addressed.

  20. Teaching Engineering Practices

    Cunningham, Christine M.; Carlsen, William S.

    2014-03-01

    Engineering is featured prominently in the Next Generation Science Standards (NGSS) and related reform documents, but how its nature and methods are described is problematic. This paper is a systematic review and critique of that representation, and proposes that the disciplinary core ideas of engineering (as described in the NGSS) can be disregarded safely if the practices of engineering are better articulated and modeled through student engagement in engineering projects. A clearer distinction between science and engineering practices is outlined, and prior research is described that suggests that precollege engineering design can strengthen children's understandings about scientific concepts. However, a piecemeal approach to teaching engineering practices is unlikely to result in students understanding engineering as a discipline. The implications for science teacher education are supplemented with lessons learned from a number of engineering education professional development projects.

    A calculation method is presented for a rhombic drive Stirling engine with a tubular heater and cooler and a screen type regenerator. Generally the equations presented describe power generation and consumption and heat losses. It is the simplest type of analysis that takes into account the conflicting requirements inherent in Stirling engine design. The method itemizes the power and heat losses for intelligent engine optimization. The results of engine analysis of the GPU-3 Stirling engine are compared with more complicated engine analysis and with engine measurements.

  2. Engineering and Software Engineering

    NASA Astrophysics Data System (ADS)

    Jackson, Michael

    The phrase ‘software engineering' has many meanings. One central meaning is the reliable development of dependable computer-based systems, especially those for critical applications. This is not a solved problem. Failures in software development have played a large part in many fatalities and in huge economic losses. While some of these failures may be attributable to programming errors in the narrowest sense—a program's failure to satisfy a given formal specification—there is good reason to think that most of them have other roots. These roots are located in the problem of software engineering rather than in the problem of program correctness. The famous 1968 conference was motivated by the belief that software development should be based on “the types of theoretical foundations and practical disciplines that are traditional in the established branches of engineering.” Yet after forty years of currency the phrase ‘software engineering' still denotes no more than a vague and largely unfulfilled aspiration. Two major causes of this disappointment are immediately clear. First, too many areas of software development are inadequately specialised, and consequently have not developed the repertoires of normal designs that are the indispensable basis of reliable engineering success. Second, the relationship between structural design and formal analytical techniques for software has rarely been one of fruitful synergy: too often it has defined a boundary between competing dogmas, at which mutual distrust and incomprehension deprive both sides of advantages that should be within their grasp. This paper discusses these causes and their effects. Whether the common practice of software development will eventually satisfy the broad aspiration of 1968 is hard to predict; but an understanding of past failure is surely a prerequisite of future success.

  3. Engine Lubricant

    1993-01-01

    PS 212, a plasma-sprayed coating developed by NASA, is used to coat valves in a new rotorcam engine. The coating eliminates the need for a liquid lubricant in the rotorcam, which has no crankshaft, flywheel, distributor or water pump. Developed by Murray United Development Corporation, it is a rotary engine only 10 inches long with four cylinders radiating outward from a central axle. Company officials say the engine will be lighter, more compact and cheaper to manufacture than current engines and will feature cleaner exhaust emissions. A licensing arrangement with a manufacturer is under negotiation. Primary applications are for automobiles, but the engine may also be used in light aircraft.

    With the development of metabolic engineering, employment of a selected microbial host for accommodation of a designed biosynthetic pathway to produce a target compound has achieved tremendous success in the past several decades. Yet, increasing requirements for sophisticated microbial biosynthesis call for establishment and application of more advanced metabolic engineering methodologies. Recently, important progress has been made towards employing more than one engineered microbial strains to constitute synthetic co-cultures and modularizing the biosynthetic labor between the co-culture members in order to improve bioproduction performance. This emerging approach, referred to as modular co-culture engineering in this review, presents a valuable opportunity for expanding the scope of the broad field of metabolic engineering. We highlight representative research accomplishments using this approach, especially those utilizing metabolic engineering tools for microbial co-culture manipulation. Key benefits and major challenges associated with modular co-culture engineering are also presented and discussed. Copyright © 2016 International Metabolic Engineering Society.

    The purpose of this ex post facto study was to describe completers and non-completers of associate's degree programs in engineering and engineering technologies and determine whether and to what extent completion in these programs is a function of selected student-related variables and institutional variables. Data from the 2004/2009 Beginning Postsecondary Students Longitudinal Study (BPS: 04/09) of associate's degree completers and non-completers in engineering and engineering technologies were accessed and analyzed through PowerStats, a web-based data analysis tool from National Center for Education Statistics (NCES). Descriptive data indicated that, proportionally, engineering and engineering technologies completers were mostly White, married, middle income, employed part-time, enrolled full-time, did not hold a high school diploma or certificate, completed Trigonometry/Algebra II, had a father who's highest education level was an associate's degree, but did not know their mother's highest level of education, completed remedial coursework, and started college with the goal of earning an associate's degree. While more males enrolled in the programs, males and females demonstrated similar completion rates, proportionally--with females showing a slightly higher percentage of completion. Results from the logistic regression further indicated that the variables significant to completion in associate's degree programs in engineering and engineering technologies were gender and enrollment size. Findings suggested that female students were more likely to earn the degree, and that the larger the institution, the more likely the student would become a completer. However, since a major limitation of the study was the small weighted sample size, the results of the study are inconclusive in terms of the extent to which the findings can be generalized to the population of students in associate's degree programs in engineering and engineering technologies. This study fills a

    This study aimed to determine theoretically, the electrical optimum power of LFG using the maximum net benefit (MNB) methodology, and taking into consideration the economic, demographic, and regional aspects of the Inter municipal Consortium of the Micro-region of the High Sapucaí for Sanitary Landfill (CIMASAS, as acronym in Portuguese), that is located in the southern part of the State of Minas Gerais, Brazil. To this end, the prognosis for a 20-year period of household solid waste generation in this region was estimated and quantified based on population data, in order to estimate the LFG production and the energy that can be generated. From this point, the optimum power for thermal power plant (TPP) by LFG was determined. The results indicated that the landfill in this region could produce more 66,293,282m 3 CH 4 (with maximum power of 997kW in 2036) in twenty years and that there would be no economic viability to generate energy from LFG, because the Net Present Value (NPV) would not be positive. The smallest population to that can achieve a minimum attractiveness rate (MAR) of 15% should be 3,700,000 inhabitants under the conditions studied. Considering the Brazilian National Electric Energy Agency (ANEEL) Resolutions, it would be 339,000 inhabitants with an installed power of 440kW. In addition, the outcome of the CIMASAS case-study demonstrated the applicability of MNB methodology for the determination of TPP optimum power. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Multiparity, risk factor of maternal and foetal morbidity and mortality, is a worldwide public health problem. In Tunisia, in spite of the activities of the national program of maternal and infantile health implanted since 1966, the multiparity is yet observed in some regions of our country. Our objective is to draw up the epidemiological profile of the multipara woman (parity<6) and the grand multipara (parity> or =6) in the sanitary district of Monastir and to study the chronological tendencies of the factors associated during a decade (from 1994 to 2003). In all, 16649 multipara were studied, representing 24% of the total women admitted for childbirth in the public motherhoods of the district. The global means age was 33,3 +/- 4,5 years with a statistical significance between multipara and grand multipara (32,7 and 35,6 respectively). The prenatal follow up was absent or inadequate for 50,2% of multipara and 62,8% of the grand multipara (p <0,001). In the decade, the main chronological tendencies are similar in the two multipara groups. Their frequency decreased from 28,5 to 19% (p<0,001), yet the age and the adequate follow up increased from 32,6 to 34 years and from 37,4 to 57,9% respectively (p<0,001). Although the multiparity is decreasing and its associated factors seem to improve, the vigilance is asked again in order to avoid the inherent risks.

    The 56-acre Muskego Sanitary Landfill site was located in the City of Muskego, Waukesha County, Wisconsin. From the 1950's to 1981, municipal waste, waste oils, paint products, and other waste were disposed of at the site. The site was separated into three disposal areas: the Old Fill Area (38 acres); the Southeast Fill Area (16 acres); and the Non-Contiguous Fill Area (4.2 acres), composed of a drum trench, north and south refuse trenches, and an L-shaped fill area, all containing waste similar to the Old Fill Area. As a result of deteriorating water quality at onsite ground water monitoring wells,more » Waste Management of Wisconsin Inc. (WMWI) and the state conducted numerous investigations that revealed elevated levels of contaminants in the ground water. Two separate areas at the site were discovered to contain buried drums and contaminated soil. The first area was located east of the Non-Contiguous Fill Area. The second area, known as the drum trench, was discovered in a portion of the Non-Contiguous Fill Area and contained 989 drums and 2,500 cubic yards of contaminated soil. The interim ROD addressed the control and remediation of the contamination sources, including landfill waste, contaminated soils, leachate, and landfill gas. The primary contaminants of concern affecting the soil and ground water were VOCs, including benzene, toluene, and xylenes; and other organics, including chlorinated ethanes, ketones, PAHs, PCBs, pesticides, phenols, and phthalates.« less
