    Bottled water consumption is increasing worldwide, despite its huge economic and environmental cost. We aim to describe personal and tap water quality determinants of bottled water use in the city of Barcelona. This cross-sectional study used data from the Health Survey of Barcelona in 2006 (N=5417 adults). The use of bottled water to drink and to cook was evaluated in relation to age, gender, educational level, district and levels of trihalomethanes (THMs), free chlorine, conductivity, chloride, sodium, pH, nitrate and aluminium in municipal tap water using Robust Poisson Regression. The prevalence of bottled water use to drink and cook was 53.9% and 6.7%, respectively. Chemical parameters in water had a large variability (interquartile range of THMs concentrations: 83.2-200.8μg/L) and were correlated between them, except aluminium. Drinking bottled water increased with educational level, while cooking with bottled water was higher among men than among women and decreased with age. After adjusting by these personal determinants, a dose-response relationship was found between concentrations of all chemicals except aluminium in tap water and bottled water use. The highest association was found for THMs, with a Prevalence Ratio of 2.00 (95%CI=1.86, 2.15) for drinking bottled water and 2.80 (95%CI=1.72, 4.58) for cooking with bottled water, among those with >150μg/L vs. water. More than half of Barcelona residents regularly drank bottled water, and the main determinant was the chemical composition of tap water, particularly THM level. Copyright © 2017.

    Full Text Available In the face of increasing and differentiating the low-cost housing demand and the trend of establishing new paradigms in the contemporary housing design, the architectural investigation has replaced into its disciplinary statement the topic of housing as central question in research and design experimentation. The city of Barcelona has codified in the last years innovative modalities of public management in social housing, offering interesting points of reflection on the idea of housing and of Mediterranean quality in urban, architectural and constructive terms. The paper proposes a key to the reading on the recent experiences of social housing in Barcelona illustrating the different forms through which architecture interprets the relationship between housing and public space, between innovation and constructive tradition.

    Storm water detention tanks are being implemented at first as a solution to the urban flooding problem and afterwards a second function was added to reduce the pollution of the sewerage waters before its overflow to the receiving bodies because these spills can contribute with up to 50% of the total pollution spilled. These solutions are often cheaper and have less impact on the urban activities than the classical solutions such as trunk sewers. In Spain, Barcelona was the first city to build this tanks to avoid flooding and also to reduce the contamination to the receiving waters, with a total volume of 492.200 m''3, operated by Clavegueram de Barcelona (Clabsa). These works have meant a big improvement in the management of the wet weather flows in Barcelona. These tanks have increased the capacity of the sewerage system and decreased the combined sewer overflows to the receiving waters (Besos river and Mediterranean sea). Another advantage is the protection of WWTP against flow variations. The environmental improvement achieved with the tanks is so hug that can even reduce the contamination spilled to the receiving waters around 30% and avoid the destruction of some ecosystems. Also, the contaminated sediments trapped in the detention tank are sen to to the WWTP so the don't reach the receiving waters. Also. the urban space close to the relieving waters are becoming more appreciated for leisure so the recovery and protection of these waters is a must. (Author)

    In a context of a shifting environmental, economic and social paradigm, European cities face a situation that is at the same time challenge and opportunity: the need for urban rehabilitation of the vulnerable degraded socio residential fabric. Public administrations in big cities and metropolitan areas are confronted with both the undercurrent need of actualization of the built stock and the rise of urban residential vulnerability. The city of Barcelona, as many others, is the result of multiple phenomena with high urban and social consequences. The socio spatial integration of immigrant population, the touristic rise and gentrification processes are current situations simultaneously taking place in the city. In parallel, a framework of economic crisis in which public investments in urban and social matters decrease, provides a temporal juncture that results into an increase of social polarization and socio economic inequality that becomes evident and expressed in the territory. This research focuses in the case of Barcelona, and presents a methodology based on a system of indicators elaborated through the exploitation of statistical data complemented with very specific data supplied by the Barcelona City Council. The accurate knowledge of socio demographic, socioeconomic and residential and urban characteristics is crucial in order to define the very complex urban dynamics that describe in the city neighbourhoods and areas. Residential vulnerability is defined as an assembly of objective conditions that relate to residential space and indicate situations of social discrimination and structural disadvantage of the population, related to a specific time and context. Thus, it is relevant to analyse the concentration of certain indicators of vulnerability in specific places or neighbourhoods, to contrast its effect on the socio-residential situation and its temporal evolution in order to identify tendencies. The present study contributes to the identification of data

    A case-control study on lung cancer and the habit of cigarette smoking was carried out in Barcelona (Spain). Cases were 103 women newly diagnosed with primary lung cancer in 10 hospitals from the study area. Histologic confirmation was given in 101 cases, of which 53 were adenocarcinoma, 19 squamous-cell carcinoma, 9 small-cell carcinoma and 20 other types. Two controls per case were selected, matched by age, residence and hospital. Compared with the never-smokers, the odds ratios (OR), with corresponding 95% confidence intervals (CI), were 1.61 (0.4 to 6.9) for ex-smokers and 3.61 (1.6 to 8.3) for current smokers. The risk of lung cancer showed a good dose-response relationship with duration of the habit, average number of cigarettes smoked daily and cumulative cigarette consumption. The risk of lung cancer increased by 62% for each 10 pack-years. Depth of inhalation also showed a remarkable effect, independently of the intensity of the habit. Although mortality and incidence rates of lung cancer among women in Spain are lower than in other developed countries, the risk of lung cancer is that which would be expected according to the pattern of the smoking habit in Spanish women.

    The use of Enteral Nutrition at Home (ENH) in the Hospital Clínico de Barcelona has grown greatly over the last decade, with a certain trend towards stabilization being observed in the last two years, but still growing at a rate of 9.2% per annum. A transverse analysis of the active patients on our ENH register at a given moment has revealed a total of 315 patients receiving treatment. The retrospective analysis of our series during 1998 gave a figure of 643 new cases. The most frequent indication for ENH was neoplasia (44%), followed by neurological pathology (28%). The administration route most frequently used was oral (66% of cases). In the oral route, oncological diagnoses were dominant (52%), whereas administration by means of a naso-gastric tube was mainly due to neurological disorders (72%). The use of PEG (12.5% of administrations via tube) was distributed between oncological and neurological patients, with a slight predominance of the first. Of those patients completing ENH in the same year, duration was in most cases (67%) less than one month. The decrease of the patient due to the underlying disorder was the main cause of termination, followed by the need for short-term nutritional support following discharge from hospital.

    ensemble of regional models (ENSEMBLES project) have been also considered. Flood events have been obtained from newspapers, reports and insurance data. The role played by prevention measures, particularly in the specific case of Barcelona, which has been recognized by UNISDR (United Nations International Strategy for Disaster Reduction) as resilient city in front of floods, is also presented. Results confirm the strong role played by the increase of urban surface (from less than 15% in 1956 to near 40% in 2009) and explore future adaptation measures in the context of the 2030 Agenda for Sustainable Development. This work has been supported by the Spanish project HOPE and the Metropolitan Area of Barcelona, and developed by an interdisciplinary team that include experts from hydrology, meteorology, geography, environmental sciences and architecture.

    Full Text Available Global sustainability is increasingly an issue of urban sustainability, being essential to encourage more benign trajectories of urbanisation. For this, there is need for a framework that could aid in the process of designing and redesigning (retrofitting cities. The aim of this paper is to present and describe the methodology of urban ecodesign, which is characterized by a systematic incorporation of environmental life cycle considerations into the design of urban systems. The paper presents a case study of neighbourhood ecodesign from the city of Barcelona (Vallbona neighbourhood. This practical experience shows that the inclusion of sustainability criteria at an early stage of the design and planning of urban systems is the best strategy for environmental protection.In addition; a methodological framework is described in order to provide planners with a structured way of designing urban settlements so as to move towards sustainable urban environments.

    Full Text Available The contradictions within the policies of requalification of the City of Barcelona have become more evident in relation to some of the most recent urban transformations, as in the case of the project for the renewal of the Diagonal-Mar area; urban space where the Forum of Cultures 2004 has been held. The Forum turned into a failure, according to the paradigm of the criticisms, on the cultural and, above all, political (or marketing level; in its urban dimension, it has been the expression of the city that mires to the global insertion: it is a urban planning which is prevalently oriented to the external demand. The regeneration of the Diagonal-Mar has shown a scant consideration of social objectives, with the creation of spaces, where the concept of value of exchange predominates over the value of use. The actor (public and above all private investors, that participated to the redaction of the project of urban renewal of the area, produced a great propagandistic effort, presenting it as an open cultural initiative which can assume also the social criticisms.A lot of social and civil organization did not participate, and their proposals have not been accepted, and so, today, urban and social processes, rebound on the success or failure of the urban planning in an important area of the city. From that, what Borja (2005 defines the “urban malaise of Barcelona” starts, over the years of social and economic growth, the inhabitants of Barcelona fell a certain malaise, which is highlighted by the today’s crisis. The big urban projects do not generate any enthusiasm, citizens feel themselves progressively less owners of the own city, the architecture of the “great singular objects” does not represent the element of identity of the society. By scanning those urban imaginaries from a theoretical-conceptual viewpoint, which is formal and empiric, the question emerges, if the punctual urban planning operation of a sector could create evaluations

    Floods are the most important natural hazard in the world. Nowadays, mitigation and adaptation strategies to reduce the impact that climate change will have on them, are a priority in most government agendas. Recent reports from the IPCC (2012, 2014) still show significant uncertainty associated with future projections of precipitation extremes. This uncertainty is higher when referred to floods and even larger when interactions with society and the changes in vulnerability are considered. Consequently, there is now a call to treat floods from a holistic perspective that integrates bottom-up (from impact and vulnerability) and top-down (from hazard) approaches (Hall et al., 2014). The study of flood risk in urban and peri-urban areas is complex and involves multiple factors. This is the case of the Metropolitan Area of Barcelona (AMB), which concentrates 43% of total population of Catalonia in less than 2% of the whole territory. The impervious soil has grown more than 200% from 1956 to 2009 (resulting in higher values of runoff), the population has increased more than 80% in the same period and, simultaneously, an improvement of the drainage system and flood prevention has been developed. As a result, we have seen that the flood risk evolution in the area holds a strong link to these human changes. Actually, floods in this region are usually due to drainage problems, flash floods in ungauged torrential catchments and, only in some occasions, river floods are produced (i.e. the Llobregat River on September 1971). But, in all the cases they are due to heavy precipitations. The main objective of the contribution is assessing the relationship between precipitation in the AMB and the social impacts produced. In order to do it, different impact indicators have been proposed, such as the population affected or the duration of the flood event (Merz et al., 2010). These indicators have been implemented for the different cases analyzed, which affected AMB for the period

    The cleanup of contaminated places with heavy metals is necessary, but environmental remediation strategies are often expensive and energy consuming. Thus, it is important to develop low-cost and environmentally friendly strategies. Phytoremediation-based technologies could provide a long-lasting solution. The study area is located in Sants, a neighbourhood in Barcelona city (Catalonia, Spain). This place was an industrial area in the last century, which was occupied by a metal smelting industry. Nowadays, the neighbours want to cultivate vegetables in this location, but the history of this area suggests that the soil is polluted by elevated concentrations of heavy metals. The aim of this work was to determine heavy metal concentration in: a) soil, to know the degree of the soil pollution; b) roots and leaves of two plant species, Brassica juncea as an accumulator plant and Solanum lycopersicum as a crop plant, to know the capacity of each species to accumulate metals, and c) drainage water, to evaluate the heavy metal mobility. The main pollutants are Cu, Pb and Zn with topsoil total concentrations about 1355, 2230 and 6239 mg•kg-1, respectively. The established background upper limits in this area in mg•kg-1 were: Cu 145, Pb 91 and Zn 326. The same soil elements for available fractions, extracted with DTPA, were slightly elevated (9.6, 5.8 and 6.7 % of total concentration). The environmental pollution implies great extractability, suggesting the plants in these soils have facility with potentially toxic elements absorption. Instead, the concentrations in subsoil are lower than in topsoil. The concentrations of Cu, Pb and Zn in the plants' leaves are greater in B. juncea 170 ± 52.7, 137 ± 46.3 and 2365 ± 860.4 mg•kg-1, than in S. lycopersicum 102.5 ± 7.1, 22.5 ± 1.3 and 1002 ± 85.2 mg•kg-1 respectively. Furthermore, they are also greater in roots than in leaves. All of them are lower than the threshold to be considered like a hyperaccumulator species

    The construction of the public space has become in the last decades something so important and fundamental in the architecture of the cities, that requires a specific discipline and a concrete study that evaluates the characteristics and actions on it. Not already from an urbanistic perspective but from its own design and constructive perspective, with its character as a place for everyone and for everything, must gather a series of elements that are unique to this space. Barcelona is one of the densest cities in the world that, since the end of the s. XX until our days, tries to solve the public space with a design of quality and optimum. The shortage of public space, which also hosts more than eight million tourists each year, makes it necessary to propose a type of meticulous intervention in order to accommodate all types of users and activities. From the first Universal Exhibition of 1888 through 1929 to the 1992 Olympics as the most important stimulus for this renewal of urban space, Barcelona has been rethinking and evolving in the modus operandi in terms of its urban space. From our professional experience as architects both in the municipal, private and university spheres, we believe that it is our responsibility to confer the public space, that is to say, the design of the urban infrastructure with the attributes necessary to consolidate it in a space Suitable for all without exception and as a place of expression of citizenship. Through the projects of public space developed in our office we will analyze this change of procedure in the construction of squares, parks and other spaces in the city of Barcelona.

    Full Text Available Urban gardens have been observed to multiply in response to crises. However, the meaning and motivations behind the emergence of gardening movements varies greatly over space and time. In this paper we argue that bottom up urban gardening initiatives taking place in Southern European countries in form of land occupation and communalization represent forms of resistance that enhance social cohesion and collective action in times of need. Specifically, this research examines the role of urban gardens in (i building community resilience and (ii articulating forms of resistance and contestation to development pressure and commodified urban lifestyles. Our research is based on data collected among 27 urban gardening initiatives in Barcelona, Spain, including 13 self-governed community gardens and 14 public gardens. Data were collected from semi-structured interviews with gardeners and with staff from the Barcelona City Council. Our results show mechanisms through which urban gardens can contribute to build resilience by nurturing social and ecological diversity, generating and transmitting local ecological knowledge, and by creating opportunities for collective action and self-organization. We further examine collectively managed gardens as urban commons that emerge as a form of resistance to the privatization of public urban space, and that offer opportunities to experiment with new models of urban lifestyles. We show how gardening initiatives can be seen to represent an emerging form of urban green commons that provides a suitable ground to ‘sow’ resilience and contestation in times of crises and socio-ecological deterioration.

    Full Text Available The religious revival of the 'North' (Europe, developed by Pentecostal missionaries of the 'South' (Latin America - Brazil, in particular, in the context of the 'reverse mission', is a dynamic process and in significant expansion. From a localized ethnography - conducted between November 2011 and April 2012 - this article analyzes the work of evangelization and gender strategies developed by two emblematic and differentiated Brazilian neo-Pentecostal religious movements, in the metropolitan area of Barcelona (Spain: the evangelical and transnationalised Universal Church of the Kingdom of God and the Catholic Charismatic Renewal group Raboni Ajaray. From a comparative anthropological study of the daily life of these two religious groups, it discusses how a "feminized" and "manly" character, respectively, define important boundaries between Catholics and evangelicals. The ethnographic data demonstrate how certain characteristics of immigrants can act as a source of social differentiation that fosters opportunities and specific doctrinal strategies for men and women, in a context of diaspora.

    Full Text Available Urban fringes set complex landscapes, in transition from rural to natural and urban, with fuzzy boundaries in mutual interdependence. The European Landscape Convention gives notorious importance to everyday landscapes, including those of suburban character. Few landscape evaluation researches are done in suburban areas, which is surprising considering its importance and abundance. This paper shows a methodology, yield on geographical information systems (GIS, for landscape assessment of suburban areas, useful in urban planning. Its main interest lies in a double assessment, which considers both landscape quality and landscape fragility, applied systematically. The procedure is applied in Muntanyes d’Ordal in the metropolitan area of Barcelona (Spain, an area with pronounced regional strengths and contrasted landscape values. Results are of important applicability and indicate a predominance of mean values, both for landscape quality and landscape fragility.

    Models of social influence have explored the dynamics of social contagion, imitation, and diffusion of different types of traits, opinions, and conducts. However, few behavioral data indicating social influence dynamics have been obtained from direct observation in "natural" social contexts. The present research provides that kind of evidence in the case of the public expression of political preferences in the city of Barcelona, where thousands of citizens supporting the secession of Catalonia from Spain have placed a Catalan flag in their balconies and windows. Here we present two different studies. 1) During July 2013 we registered the number of flags in 26% of the electoral districts in the city of Barcelona. We find that there is a large dispersion in the density of flags in districts with similar density of pro-independence voters. However, by comparing the moving average to the global mean we find that the density of flags tends to be fostered in electoral districts where there is a clear majority of pro-independence vote, while it is inhibited in the opposite cases. We also show that the distribution of flags in the observed districts deviates significantly from that of an equivalent random distribution. 2) During 17 days around Catalonia's 2013 national holiday we observed the position at balcony resolution of the flags displayed in the facades of a sub-sample of 82 blocks. We compare the 'clustering index' of flags on the facades observed each day to thousands of equivalent random distributions. Again we provide evidence that successive hangings of flags are not independent events but that a local influence mechanism is favoring their clustering. We also find that except for the national holiday day the density of flags tends to be fostered in facades located in electoral districts where there is a clear majority of pro-independence vote.

    In recent years, GHG inventories of cities have expanded to include extra-boundary activities that form part of the city's urban metabolism and economy. This paper centers on estimating the emissions due to seaports, in such a way that they can be included as part of the city's inventory or be used by the port itself to monitor their policy and technology improvements for mitigating climate change. We propose the indicators GHG emissions per ton of cargo handled or per passenger and emissions per value of cargo handled as practical measures for policy making and emission prevention measures to be monitored over time. Adapting existing methodologies to the Port of Barcelona, we calculated a total of 331,390 tons of GHG emissions (CO{sub 2} equivalents) for the year of 2008, half of which were attributed to vessel movement (sea-based emissions) and the other half to port, land related activities (land-based emissions). The highest polluters were auto carriers with 6 kg of GHG emissions per ton of cargo handled. Knowing the highest emitters, the port can take action to improve the ship's activities within the port limits, such as maneuvering and hotelling. With these results, the port and the city can also find ways to reduce the land-based emissions. - Research highlights: {yields} Adapting existing methodologies to the Port of Barcelona (PoB), we calculated a total of 331,390 tons of GHG emissions for the year of 2008, half of which were attributed to vessel movement (sea-based emissions) and the other half to port, land related activities (land-based emissions) {yields} Emissions per ton of cargo handled is proposed as an indicator to pin point high polluting vessels-a measure independent of the city the port belongs to. For 2008, the highest polluters were auto carriers with 6 kg of GHG emissions per ton of cargo handled. {yields} An additional measure of emissions per value of cargo handled is proposed to complement the emissions per weight

    Full Text Available Participatory evaluation of aspiring sustainable schools and their pedagogical potential has recently come into focus. A few authors have made a significant start in examining schools as both environmentally and socially sustainable environments, which might simultaneously represent the ‘third teacher’. However, discussion around this idea is new in Spain. This paper describes a participatory post-occupancy study conducted with teachers and pupils in Fort Pienc School, Barcelona, Spain. Findings reveal the pedagogical potential of the school’s spaces and fabric, characterised as ‘sustainable’, and highlight the aspects that the research participants feel are performing and underperforming. The paper concludes that if we want sustainable schools to be a strategy for renovating the educational process and for leading us towards a better tomorrow globally and locally,  new models for exploring the pedagogical potential of sustainable schools should be developed and the efforts of all relevant parties synchronised; from architects to governments, from pupils to teachers.

    Different models of social influence have explored the dynamics of social contagion, imitation, and diffusion of different types of traits, opinions, and conducts. However, few behavioral data indicating social influence dynamics have been obtained from direct observation in `natural' social contexts. The present research provides that kind of evidence in the case of the public expression of political preferences in the city of Barcelona, where thousands of citizens supporting the secession of Catalonia from Spain have placed a Catalan flag in their balconies. We present two different studies. 1) In July 2013 we registered the number of flags in 26% of the the city. We find that there is a large dispersion in the density of flags in districts with similar density of pro-independence voters. However, we find that the density of flags tends to be fostered in those electoral district where there is a clear majority of pro-independence vote, while it is inhibited in the opposite cases. 2) During 17 days around Ca...

    Full Text Available Abstract Background Asbestos related diseases include a number of conditions due to inhalation of asbestos fibres at work, at home or in the environment, such as pleural mesothelioma, asbestosis and calcified pleural plaques. Few epidemiological studies have established the incidence of asbestos related diseases in our area. The present proposal is based on a retrospective study externally funded in 2005 that is currently taking place in the same area and largely carried out by the same research team. The aim of the study is to achieve a comprehensive and coordinated detection of all new cases of Asbestos Related Diseases presenting to primary care practitioners. Methods/design This is a multicentre, multidisciplinary and pluri-institutional prospective study. Setting 12 municipalities in the Barcelona province within the catchment area of the health facilities that participate in the study. Sample This is a population based study, of all patients presenting with diseases caused by asbestos in the study area. Measurements A clinical and epidemiological questionnaire will be filled in by the trained researchers after interviewing the patients and examining their clinical reports. Discussion Data on the incidence of the different Asbestos Related Diseases in this area will be obtained and the most plausible exposure source and space-time-patient profile will be described. The study will also improve the standardization of patient management, the coordination between health care institutions and the development of preventive activities related with asbestos exposure and disease.

    la envejecida estructura de edad de los pacientes autóctonos y plantea la necesidad de recuperar el mayor peso de los servicios de ginecología-obstetricia y pediatría. El hecho de que exista menor consumo de recursos por alta hospitalaria en la población inmigrante de países de renta baja contradice la relación esperada de inmigrante-peor situación socioeconómica-mayor intensidad de consumo de recursos por alta hospitalaria. Deben proponerse nuevas hipótesis de trabajo y análisis que permitan explicar esta realidad.Objective: Although the immigrant population in cities such as Barcelona has tripled in the last five years, until now the impact of this group on the health system has not been rigorously evaluated. The aim of this study was to compare hospital resource utilization among the immigrant population with that among the native population through case mix, demographic characteristics and hospital day use. Material and methods: We analyzed 15,057 discharges from Hospital del Mar in Barcelona in 2000. This hospital attends 60% of admissions from the Ciutat Vella district. In 2000, 21% of the population of this district were immigrants. Socio-demographic patient characteristics and case mix were compared between the immigrant and the native population. Hospital resource use was compared according to age, case mix (diagnosis related groups and seriousness (severity, complications and comorbidities of the events requiring medical care. Results: The case mix of the immigrant population differed from that of the autochthonous population due to pronounced ge differences and a higher fertility rate. Thirty-three percent of immigrant admissions were for deliveries. The mean cost of discharge of immigrants from low-income countries was 30% lower than that for the remaining discharges. After adjusting for age, case mix and severity, length of stay among the immigrant population was significantly shorter. A 5% reduction was found after adjusting for case mix and a

    Full Text Available BACKGROUND: The aim of the present study is to evaluate the impact of glucose-lowering agents in the risk of cancer in a large type 2 diabetic population. METHODS: A nested case-control study was conducted within a defined cohort (275,164 type 2 diabetic patients attending 16 Primary Health Care Centers of Barcelona. Cases (n = 1,040 comprised those subjects with any cancer diagnosed between 2008 and 2010, registered at the Cancer Registry of Hospital Vall d'Hebron (Barcelona. Three control subjects for each case (n = 3,120 were matched by age, sex, diabetes duration, and geographical area. The treatments analyzed (within 3 years prior to cancer diagnosis were: insulin glargine, insulin detemir, human insulin, fast-acting insulin and analogues, metformin, sulfonylureas, repaglinide, thiazolidinediones, dipeptidyl peptidase-4 inhibitors, and alpha glucosidase inhibitors. Conditional logistic regressions were used to calculate the risk of cancer associated with the use of each drug adjusted by age, BMI, dose and duration of treatment, alcohol use, smoking habit, and diabetes duration. RESULTS: No differences were observed between case and control subjects for the proportion, dose or duration of exposure to each treatment. None of the types of insulin and oral agents analyzed showed a significant increase in the risk of cancer. Moreover, no cancer risk was observed when glargine was used alone or in combination with metformin. CONCLUSIONS: Our results suggest that diabetes treatment does not influence the risk of cancer associated with type 2 diabetes. Therefore, an eventual increase of cancer should not be a reason for biasing the selection of any glucose-lowering treatment in type 2 diabetic population.

    The nematode Strongyloides stercoralis has a very particular autoinfection life-cycle which leads to chronic infections remaining undetected for decades. However, hyperinfection can occur in patients receiving immunotherapy resulting in high mortality rates. The main objective of this study was to assess the results of a 10-year multicenter surveillance program performed in an area with dense immigration in Barcelona, Spain. From January 2003 to December 2012, all individuals with Strongyloides stercoralis infection attending the four centers with diagnostic capability in the North Metropolitan area of Barcelona were recorded. The annual detection rate was 0.2 new diagnosed cases x10 000 inhabitants/year and 1 case x10 000 immigrants/year. Many patients were immigrants (63; 90.0%), asymptomatic (45; 64.3%) and with a high eosinophil count (63; 90.0%). Immunosuppression was present in 11 (15.7%) patients, among whom two (2.8%) cases of disseminated hyperinfection were recorded. Ivermectin was prescribed in 45 (76.3%) and albendazole in 14 (23.7%). Following treatment seven patients (11.9%) receiving albendazole presented relapse, that is, albendazole failed to clear the parasite in 50% of these drug-treated patients (p Strongyloides stercoralis diagnosed could be considered as imported by immigrants, most being asymptomatic and with eosinophilia. The infection is probably largely underestimated and population-based studies are needed to determine its true prevalence. Meanwhile, diagnosis must be based on active investigation of the helminth (serology and feces culture), especially in immunocompromised patients. The implementation of pre-immunosuppression protocols with the aim of identifying Strongyloides stercoralis is encouraged with empirical treatment with ivermectin being recommended in sites without diagnostic facilities.

    The analytical methodology and the concentration levels of geosmin and other natural compounds in raw water from Llobregat river and tap water from Barcelona is shown. Geosmin, a compound routinely analyzed in our laboratory is the compound causing odor episodes in our samples at levels higher than 10 ng/1. The effectiveness of the treatment in the Sant Joan Despi water works plant has allowed the removal of geosmin at levels below the limit of detection of the method (<5 ng/1). Neither 2-methyl-isoborneol (MIB) nor 2-alkyl-3-methoxypirazines have been detected among other compounds with low odor threshold concentrations (OTC). (Author) 39 refs.

    The 18th biannual conference of GIREP was held in Barcelona from 27 August to 1 September 2000. GIREP stands for Groupe International de Recherche sur l'Enseignement de la Physique. Some 400 delegates from 53 countries attended the conference, whose main concern was Physics Teacher Education beyond 2000. All contributions had to made in English. A conference like this needs to be singularly interesting to keep delegates away from the sunsoaked attractions and delights of one of the most exciting cities in the world - even if some of the excitement comes from wondering whether or not you are going to get your pocket picked. A typical conference day begins with two or three plenary lectures in the morning, with the afternoon given over to a set of nine parallel sessions. These sessions consisted of tightly timetabled 20 minute talks or other types of presentation. This meant that even the most dedicated delegate could get to little more than 10% of the over 200 sessions that were on offer in the afternoons. The event was organized by Catalonian locals working at the conference site, the Universitat Autonoma de Barcelona, and was superbly smooth. The list of organizations supporting the conference is too long to record, but ranged from the European Commission to Barcelona Science Museum. The UK can boast (if that is the right word) just 11 paid-up members of GIREP, which at about £10 per annum is hardly an expensive club - next year it goes up to 20 Euros - and the fee is worth it for the excellently produced book or CD-ROM of the conference proceedings. These contain a great deal of wisdom, plus the fair amount of infuriating rubbish that tends to be generated by educational research. I write here with all the prejudices of an aged ex-teacher, of course. The first morning lecture was given by Jon Ogborn, who used his recent work as organizer of the IoP post-16 Initiative to give some details of the Advancing Physics AS and A2 and make some general points about

The international image of Barcelona has come to be associated with an innovative urban model known as the “Barcelona model”, which dates back to the 1980s. This model is not limited to such central aspects of urban planning as public policies and new economic strategies. Instead, some of its key features are concerned withsocial inclusion, urban culture and citizen participation. However, the model itself has evolved over time and has been the object of heated debates and controversy. The aim of the article is to discuss this model and some of the main praises and criticisms it raised. This is done with a view to contributing to the debate around the following challenge: how are we to achieve an adequate balance between short-term projects and long-term public and private urban planning strategies, as well as between public leadership and social consensus? The authors of the articles included in this issue ofFinisterra – for which this article also serves as an introduction – have undertaken substantial research on the political, economic and social processes that drive this city and its metropolitan area. They highlight some of the complex situations that arise at various scales within the context of this model and they discuss their various consequences.

    The presentation is directed to the description of the actual geodetic infrastructure of Barcelona harbour with three tide gauges of different technologies for sea level determination and contribution to regional sea level rise and understanding past and present sea level rise in the Barcelona harbour. It is intended that the overall system will constitute a CGPS Station of the ESEAS (European Sea Level) and TIGA (GPS Tide Gauge Benchmark Monitoring) networks. At Barcelona harbour there is a MIROS radar tide gauge belonging to Puertos del Estado (Spanish Harbours).The radar sensor is over the water surface, on a L-shaped structure which elevates it a few meters above the quay shelf. 1-min data are transmitted to the ENAGAS Control Center by cable and then sent each 1 min to Puertos del Estado by e-mail. The information includes wave forescast (mean period, significant wave height, sea level, etc.This sensor also measures agitation and sends wave parameters each 20 min. There is a GPS station Leica Geosystems GRX1200 GG Pro and antenna AX 1202 GG. The Control Tower of the Port of Barcelona is situated in the North dike of the so-called Energy Pier in the Barcelona harbor (Spain). This tower has different kind of antennas for navigation monitoring and a GNSS permanent station. As the tower is founded in reclaimed land, and because its metallic structure, the 50 m building is subjected to diverse movements, including periodic fluctuations due to temperature changes. In this contribution the 2009, 2011, 2012, 2013 and 2014 the necessary monitoring campaigns are described. In the framework of a Spanish Space Project, the instrumentation of sea level measurements has been improved by providing the Barcelona site with a radar tide gauge Datamar 2000C from Geonica S.L. in June 2014 near an acoustic tide gauge from the Barcelona Harbour installed in 2013.

    A field study was conducted from July to September 2000 to assess ozone (O{sub 3}) phytotoxicity in Barcelona and surrounding areas of Catalonia (NE Spain) by using tobacco plants Bel-W3 and Populus nigra 'Brandaris' as bioindicators. The study was conducted simultaneously at eight sites where ozone concentrations and meteorological variables were continuously monitored. The ozone levels correlated well with ozone injury on the Bel-W3 cultivar, especially at stations established in the urban area of Barcelona, and in the first months of summer. In the second half of summer plants showed a decreasing efficiency in its biomonitoring capacity. The behaviour of Populus as bioindicator or biomonitor was less satisfactory. For both species it is necessary to improve cultivation conditions since water deficits seem to play an important role in bioindication in the Mediterranean region. (orig.)

    Full Text Available In this paper, the author will reflect on the management of public spaces in Barcelona through the case of sex work. The different ways that the Barcelona City Council has promoted the control and restriction of the free exercise of street sex work will be discussed. Recognising that the spaces are not fully accessible to everyone, the model of "civility" that Barcelona plans to implement will be explained. As a result of former zoning practices, there is a political will to make this activity "invisible", which perpetuates the vulnerability of sex workers themselves. En este artículo la autora reflexionará sobre la gestión del espacio público en Barcelona a través del caso del trabajo sexual. Se analizarán las distintas modalidades que el Ayuntamiento de Barcelona ha promovido para, en definitiva, controlar y restringir el libre ejercicio del trabajo sexual callejero. Partiendo del reconocimiento que los espacios no son plenamente accesibles para todas y todos, se explicará el modelo de “civismo” que Barcelona pretende implementar. Mediante antiguas prácticas de zonificación, se observa una voluntad política de invisibilizar esta actividad al mismo tiempo que se perpetúa la vulnerabilidad de las propias trabajadoras.Download this paper from SSRN: http://ssrn.com/abstract=1953623

    Full Text Available In this paper the catastrophic and extraordinary floods occurring in Barcelona County (Catalonia, NE Spain are studied, in order to characterise the temporal evolution of extreme flash floods in that area and their main features. These events usually cause economical losses and major problems for undertaking daily activity in Barcelona city. This kind of floods is a very common feature in the North-east of Spain and they are recorded every year in some point of Catalonia. This contribution also shows the frequency of those events, within the framework of all the floods that have occurred in Barcelona since the 14th century, but also describes the flooded area, urban evolution, impacts and the weather conditions for any of most severe events. The evolution of flood occurrence shows the existence of oscillations in the earlier and later modern age periods that can be attributed to climatic variability, evolution of the perception threshold and changes in vulnerability. A great increase of vulnerability can be assumed for the period 1850-1900. The analysis of the time evolution for the Barcelona rainfall series (1854-2000 shows that no trend exists, although, due to the changes in urban planning, flash-floods impact has changed over this time. The number of catastrophic flash floods has diminished, although the extraordinary ones have increased.

This article begins by evaluating the extent of the tertiary sector in Barcelona through the development of several macroeconomical indicators. Then we study the centralising tendency in the location of certain tertiary activities, especially those involved in decision and management, and those of the recently growing producer services. Afterwards we look at tertiary activities relevance as an instrument of urban politics in general, and in the case of Barcelona, in particular. Finally, we foresee the situation of certain branches with major potencial growth such as tourism, health or financial services.

    Full Text Available Mastitis is an important disease which causes economic losses in the water buffalo breeding. According to severity, duration and primary, mastitis is generally classified as clinical and subclinical. Because of contamination from other animals in the herd, subclinical mastitis is a important dairy herd problem. However, clinical mastitis is a clinical case created by deformation of udder gland and decreasing milk yield. Staphylococcus aureus, Escherichia coli, Streptococcus agalactia and Streptococcus dysgalactia are in clinical mastitis, but Escherichia coli, Staphylococcus aureus, Pseudomonas, Streptococcus agalactia and Streptococcus dysgalactia are the most common isolated microorganisms in subclinical mastitis. Due to mastitis caused by these microorganisms in Water Buffalo, abnormality in the structure of milk are observed, and it causes economic losses to farmers from reduced production. Therefore, the detection of effective factors on mastitis and taking of the necessary precautions are very important. In this review, mastitis case in water Buffalo and its effects were discussed.

Esta iniciativa surgió de los sectores higienistas y pedagógicos, otorgando una solución a la falta de legislación educativa vigente, que no contemplaba la gimnástica esco-lar. La respuesta del Ayuntamiento se entronca con las demandas regeneracionistas que encuen-tran el apoyo de los profesores de gimnástica. Aunque el proyecto no estuvo exento de dificulta-des, fue un firme paso para manifestar la evidencia de la necesaria oficialización de la educación física en la primera enseñanza.

    Urban groundwater is a valuable resource since its quantity is larger than frequently expected due to additional recharge sources (Lerner, 2002; Vázquez-Suñé et al., 2003). Its interaction with the complex infrastructures network makes the water authorities a challenge to ensure a proper water management. Necessary datasets to ensure a suitable water management have normally different origins and formats. At the same time, the water management of a city involves different decision makers with different knowledges. In this scenario, it is a necessity to create a common environment where different actors would be able to understand and analyze problems in the same way. It should be also necessary to store, analyze and visualize all the required data in the same formats within its geographical context by using standardized specific tools. To apply these recommendations for the urban groundwater management of the Barcelona City Council, we have implemented a software platform developed in a Geographic Information System (GIS) environment. These GIS-based tools will give support to the users for storing, managing, and analyzing geological, hydrogeological and hydrochemical data in 2D and in a 3D context (Velasco et al., 2013). This implementation will improve the groundwater management in Barcelona city optimizing the analysis and decision making processes. References Lerner, D.N., (2002).

  2. Water Quality Protection from Nutrient Pollution: Case ...

    Science.gov (United States)

    Water bodies and coastal areas around the world are threatened by increases in upstream sediment and nutrient loads, which influence drinking water sources, aquatic species, and other ecologic functions and services of streams, lakes, and coastal water bodies. For example, increased nutrient fluxes from the Mississippi River Basin have been linked to increased occurrences of seasonal hypoxia in northern Gulf of Mexico. Lake Erie is another example where in the summer of 2014 nutrients, nutrients, particularly phosphorus, washed from fertilized farms, cattle feedlots, and leaky septic systems; caused a severe algae bloom, much of it poisonous; and resulted in the loss of drinking water for a half-million residents. Our current management strategies for point and non-point source nutrient loadings need to be improved to protect and meet the expected increased future demands of water for consumption, recreation, and ecological integrity. This presentation introduces management practices being implemented and their effectiveness in reducing nutrient loss from agricultural fields, a case analysis of nutrient pollution of the Grand Lake St. Marys and possible remedies, and ongoing work on watershed modeling to improve our understanding on nutrient loss and water quality.

    Using Barcelona and Shanghai as case studies, we examined the nature-based solutions (NBS) in urban settings-specifically within cities experiencing post-industrialization and globalization. Our specific research questions are: (1) What are the spatiotemporal changes in urban built-up land and green space in Barcelona and Shanghai? (2) What are the relationships between economic development, exemplified by post-industrialization, globalization, and urban green space? Urban land use and green space change were evaluated using data derived from a variety of sources, including satellite images, landscape matrix indicators, and a land conversion matrix. The relationships between economic development, globalization, and environmental quality were analyzed through partial least squares structural equation modeling based on secondary statistical data. Both Barcelona and Shanghai have undergone rapid urbanization, with urban expansion in Barcelona beginning in the 1960s-1970s and in Shanghai in the last decade. While Barcelona's urban green space and green space per capita began declining between the 1950s and 1990s, they increased slightly over the past two decades. Shanghai, however, has consistently and significantly improved urban green space and green space per capita over the past six decades, especially since the economic reform in 1978. Economic development has a direct and significant influence on urban green space for both cities and post-industrialization had served as the main driving force for urban landscape change in Barcelona and Shanghai. Based on secondary statistical and qualitative data from on-site observations and interviews with local experts, we highlighted the institution's role in NBS planning. Furthermore, aspiration to become a global or globalizing city motivated both cities to use NBS planning as a place-making tool to attract global investment, which is reflected in various governing policies and regulations.

    To determine the frequency and characteristics of suspected drug-facilitated sexual assault (DFSA) among the victims of sexual assault in Barcelona. Prospective study of every adult consulting an emergency service because of alleged sexual assault and receiving forensic assessment in the city of Barcelona in 2011. A total of 35 of 114 cases (30.7%) met suspected DFSA criteria. Compared with the other victims, suspected DFSA cases were more likely to experience amnesia, to have been assaulted by night, after a social situation and by a recently acquainted man, to have used alcohol before the assault and to be foreigners. In this group ethanol was detected in blood or urine in 48.4% of analyzed cases; their mean back calculated blood alcohol concentration was 2.29g/l (SD 0.685). Also, at least one central nervous system drug other than ethanol was detected in 60,6%, mainly stimulant drugs of abuse. Suspected DFSA is frequent among victims of alleged sexual assault in Barcelona nowadays. The depressor substance most commonly encountered is alcohol, which contributes to victims' vulnerability.

    2014-08-01

    After World War I, members of the teaching profession in Spain were interested in appropriating psychological measurement and bringing it within the expertise of their occupational field, with the intention of upgrading their profession. As professionals devoted to the child, educators attempted to explore the infantile psyche using intelligence tests, with the intention of making scientific contributions to the field of psychology. In the present article we take as a key event one particular application enacted by a Catalan teacher, and insert that case study into the complex local scientific and educational context. It was a context in which the professional interests of teachers competed with those of school physicians, psychologists, and pedologists, at a time when important changes in pedagogical methods and school systems were under way. In the hand of teachers, intelligence testing was mainly seen as a malleable method on which to base daily educational practice on a more individualized and scientific basis. The historical analysis of the case turned out to be instrumental in the identification of common features and particularities attributable to specific local needs. In a society where public schooling competed with private schools, the results of mental testing were used to demonstrate publicly the excellent intellectual level of children attending a public graded primary school in Barcelona.

    Full Text Available Building A creative Barcelona: new actors, new strategies.Barcelona is under the international spotlight. The city that triumphed with the organisation of the Olympic Games in 1992 now wants to become a 21st Century creative city. In order to achieve this goal, the city must establish conditions that facilitate the emergence of a shared discourse around its ability to become an attractive city for creative talent and for businesses. The recognition of the historical-economic heritage, as a starting point for the creative city, along with the driving role played by culture in the generation of a exclusive and distinctive experience, turnBarcelona into a unique city. However, this is not sufficient. The participation and involvement of all the actors in a shared strategy pose significant challenges to Barcelona, as does the need to minimise the negative effects that inevitably accompany success. Companies, institutions and citizens constitute the city’s best assets: they must work in partnership and take advantage of the synergies generated amongst them. Consensus and participation are more than mere utopias in Barcelona: they have become requirements for the city of tomorrow. Moreover, leadership in Barcelona is largely left to public initiative: the emergence of linkages across the needs of the various creative sectors, based on public intervention mechanisms is the best way to ensure success.

    Myopia is one of the major causes of low visual acuity during childhood, and hence of the need for spectacles. It is generally more prevalent in urban areas where children are often less exposed to green spaces than in rural areas. This study evaluated the association between exposure to green space and use of spectacles (as a surrogate measure for myopia) in a cohort of 2727 schoolchildren (7-10 years old) recruited from 39 primary schools in Barcelona (2012-2015). We assessed exposure to green spaces by characterizing outdoor surrounding greenness at home and school and during commuting using satellite data on greenness (Normalized Difference Vegetation Index). We also obtained data on the annual average time children spent playing in green spaces through questionnaires. Cross-sectional analyses were conducted based on prevalent cases of spectacles use at baseline data collection campaign and longitudinal analyses based on incident cases of spectacles use during the three-year period between the baseline and last data collection campaigns. An interquartile range (IQR) increase in exposure to green space at home (500m buffer) and school and during commuting was associated with respectively 14% (95% CI: 2%, 26%), 27% (95% CI: 6%, 44%), and 20% (95% CI: 5%, 33%) decrease in spectacles use in cross-sectional analyses. In longitudinal analyses, we observed a reduction of 23% (95% CI: 4%, 39%) and 34% (95% CI: 2%, 55%) associated with an IQR increase in greenness at home and school, respectively. Moreover, an IQR increase in time playing in green spaces was associated with a 28% (95% CI: 7%, 45%) reduction in the risk of spectacles use in the longitudinal analysis. Our observed reduced risk of spectacles use associated with higher contact with green space calls for more refined studies of the association between green spaces and refractive errors of visions.

    2015-06-01

    Full Text Available The world’s current utilisation of water, allied to the forecasted increase in our dependence on it, has led to the realisation that water as a resource needs to be managed. The scarcity and cost of water worldwide, along with water management practices within Europe, are highlighted in this paper. The heavy dependence of energy generation on water and the similar dependence of water treatment and distribution on energy, collectively termed the water–energy nexus, is detailed. A summary of the recently launched ISO14046 Water Footprint Standard along with other benchmarking measures is outlined and a case history of managing water using the Energy Management Standard ISO50001 is discussed in detail. From this, the requirement for a methodology for improvement of water management has been identified, involving a value system for water streams, which, once optimised will improve water management including efficiency and total utilisation.

    Full Text Available This study aims to explain the 1869 Republican up-rising in Barcelona by adding an evidence unknown to the historiography of republicanism: its confluence with a massive cotton workers strike that paralyzed the first industry of the city from august to October in the aftermath of the armed fighting. So, the 1869 Republican up-rising in Barcelona can be seen as a relevant case study in order to understand some major issues on 1868-1874 Spain: the nature of the rank-and-file/leadership relationship into the republican movement; the social (and not only political sources of popular or plebeian unrest; and the so many faces of the «cuestión obrera» in industrial and liberal societies, as Barcelona had been since the 1830s.

    "Water problems" are fundamentally human problems -- aligning water quality and quantity with human aspirations. In the U.S., however, the few ongoing efforts to repeatedly observe humans in relation to water at large scale are disjointed both with each other and with observing systems for water quality and quantity. This presentation argues for the systematic, coordinated, and on-going collection of primary data on humans, spanning beliefs, perceptions, behaviors, and institutions, alongside the water environments in which they are embedded. Such an enterprise would advance not only water science and related policy and management decisions, but also generate basic insights into human cognition, decision making, and institutional development as they relate to the science of sustainability. In support of this argument, two types of original analyses are presented. First, two case studies using existing data sets illustrate methodological issues involved in integrating natural system data with social data at large scale: one concerns the influence of water quality conditions on personal efforts to conserve water and contribute financially to environmental protection; the other explores relationships between recreation behavior and water quality. Both case studies show how methodological differences between data programs seriously undercut the potential to draw inference about human responses to water quality while also illustrating the scientific potential that could be realized from linking human and scientific surveys of the water environment. Second, the results of a survey of water scientists concerning important scientific and policy questions around humans and water provide insight into data collection priorities for a coordinated program of observation.

  12. Using Case Studies to Teach Interdisciplinary Water Resource Sustainability

    2012-12-01

    Teaching about water resources and often emphasizes the biophysical sciences to understand highly complex hydrologic, ecologic and engineering systems, yet most impediments to improving management emerge from social processes. Challenges to more sustainable management often result from trade-offs among stakeholders (e.g., ecosystem services, energy, municipal use, and agriculture) and occur while allocating resources to competing goals of economic development, social equity, and efficient governance. Competing interests operating across multiple scales can increase tensions and prevent collaborative resolution of resource management problems. Here we discuss using specific, place-based cases to teach the interdisciplinary context of water management. Using a case approach allows instructors to first explore the geologic and hydrologic setting of a specific problem to let students understand where water comes from, then how it is used by people and ecosystems, and finally what conflicts arise from mismatches between water quality, quantity, timing, human demand, and ecosystem needs. The case approach helps students focus on specific problem to understand how the landscape influences water availability, without needing to first learn everything about the relevant fields. We look at geology, hydrology and climate in specific watersheds before addressing the human and ecosystem aspects of the broader, integrated system. This gives students the context to understand what limits water availability and how a water budget constrains possible solutions to sustainability problems. It also mimics the approach we have taken in research addressing these problems. In an example case the Spokane Coeur D'Alene basin, spanning the border between SE Washington and NW Idaho, includes a sole source aquifer system with high exchange between surface water and a highly conductive aquifer. The Spokane River does not meet water quality standards and is likely to face climate driven shifts

  13. The origin of the geothermal anomaly identified in the Barcelona underground (Spain): Future perspectives of this urban geothermal resource

    During the drilling of line 9 of the Barcelona underground (Spain), a geothermal anomaly was detected, in which groundwater temperature was found to be up to 50°C. Previously, during the construction of the Fondo station in Santa Coloma de Gramanet (SCG), temperatures up to 37°C were already detected in this area. To study the feasibility of a future energy exploitation of the geothermal anomaly, a local and regional study is being undertaken. We present the first results of the new study. The objectives of this study were (1) to understand the flux regime of the hydrothermal system on both, local and large scale, (2) to explain the origin of the identified geothermal anomaly in SCG, and (3) to know the quality of the geothermal potential of the underground resources. To achieve these goals, different numerical models of groundwater flow and heat transport were performed. The area of study is constituted mainly of low permeability Palaeozoic granodiorites strongly weathered towards the top (lehm). These materials are affected by two sets of faults: the first one consists of porphyrýs dikes with a SW-NE direction and the second fault family which presents a NW-SE direction (Vázquez-Suñé et al., 2016). In the southeast area, the Quaternary deposits of the Besós River delta overlap these Palaeozoic materials. In spite of being a regional model, all these geological features have been incorporated in a complex mesh with more than 2.5 million finite elements. The results obtained suggest that in the case of SCG, the thermal anomaly found on the surface would have its origin in the rapid ascent of the hot water through these fracturing planes. Understanding the hydrogeothermal operation of the SCG system in detail and its possible temporal evolution will be of great interest for future evaluation, monitoring and management of the geothermal resources found, as well as to understand the interaction of these systems with urban infrastructures.

    The data described in this article were collected daily over the period June 10, 2010, to November 25, 2012, from the website of the Spanish Ministry of Industry, Energy and Tourism. The database includes information about fuel stations regarding to their prices (both gross and net of taxes), brand, location (latitude and longitude), and postal code in the Spanish provinces of Madrid and Barcelona. Moreover, obtaining the postal codes has allowed us to select those stations that are operating within the metropolitan areas of Madrid and Barcelona. By considering those fuel stations that uninterruptedly provided prices during the entire period, the data can be especially useful to explore the dynamics of prices in fuel markets. This is the case of Balaguer and Ripollés (2016), "Asymmetric fuel price responses under heterogeneity" [1], who, taking into account the presence of the potential heterogeneity of the behaviour of fuel stations, used this statistical information to perform an analysis on asymmetric fuel price responses.

    Full Text Available The data presented in this article is an initial contribution to the study of musical score business in Barcelona between 1792 and 1834. It includes information about the places where printed and handwritten musical scores could be purchased as well as about the people involved in this business (booksellers, instrument makers, musicians, copyists and small business owners not specialised in music. It also gives specifics about the commercial system through which the purchases were made (direct sales, subscription, hire, exchange, batches, in notebooks or through music newspapers, the repertoire and, in some cases, the price of the musical score. The intensity of the musical score business, particularly from 1814, once the War of Independence had ended, is a clear sign of the high development of the activity and the musical culture of Barcelona, and demonstrates that Spain formed part of a European distribution network for musical scores.

    Full Text Available Abstract Background Finnish and Swedish waste water systems used by the forest industry were found to be exceptionally heavily contaminated with legionellae in 2005. Case presentation We report two cases of severe pneumonia in employees working at two separate mills in Finland in 2006. Legionella serological and urinary antigen tests were used to diagnose Legionnaires' disease in the symptomatic employees, who had worked at, or close to, waste water treatment plants. Since the findings indicated a Legionella infection, the waste water and home water systems were studied in more detail. The antibody response and Legionella urinary antigen finding of Case A indicated that the infection had been caused by Legionella pneumophila serogroup 1. Case A had been exposed to legionellae while installing a pump into a post-clarification basin at the waste water treatment plant of mill A. Both the water and sludge in the basin contained high concentrations of Legionella pneumophila serogroup 1, in addition to serogroups 3 and 13. Case B was working 200 meters downwind from a waste water treatment plant, which had an active sludge basin and cooling towers. The antibody response indicated that his disease was due to Legionella pneumophila serogroup 2. The cooling tower was the only site at the waste water treatment plant yielding that serogroup, though water in the active sludge basin yielded abundant growth of Legionella pneumophila serogroup 5 and Legionella rubrilucens. Both workers recovered from the disease. Conclusion These are the first reported cases of Legionnaires' disease in Finland associated with industrial waste water systems.

    Full Text Available Fresh water is a finite resource that is critically needed bysociety for a variety of purposes. The demand for freshwater will grow as the world population and global livingstandard increase, and fresh water shortages will becomemore commonplace. This will put significant stress onsociety. It has been argued that fresh water may becomethe next oil, and efforts have to be made to better manageits fresh water consumption by agricultural and domesticusers. Industry also uses large amounts. Surprisingly, onlyrecently is serious attention being directed toward waterrelatedissues. This effort to quantify the water footprint ofa manufactured product represents one of the first initiativesto characterize the role of water in a discrete good.This study employed a life cycle assessment methodologyto determine the water footprint of a pitcher water filter.This particular product was selected because many waterintensivematerials and processes are needed to produceits major components: for example, agricultural processesused to produce activated carbon and petrochemicalprocesses used to produce the polypropylene casing. Inaddition, a large amount of water is consumed during theproduct’s use phase. Water data was obtained from theEcoinvent 2.1 database and categorized as either beingassociated with blue or green water.The blue water footprint (surface water consumption forthe pitcher water filter was 76 gallons per filter: 10 gallonsconsumed for materials extraction, 15 gallons for themanufacturing stage, and 50 gallons during the use phase.The green water footprint (precipitation was associatedwith the cultivation of the coconut tree; activated carbonis obtained from the coconut shells. The green waterfootprint was calculated to be 164 gallons per filter.The overall water footprint was 240 gallons per filter;the filter footprint is heavily dominated by green water(68% rather than blue water (32%.

    While the water dependency of water-scarce nations is well understood, this is not the case for countries in temperate and humid climates, even though various studies have shown that many of such countries strongly rely on the import of water-intensive commodities from elsewhere. In this study we introduce a method to evaluate the sustainability and efficiency of the external water footprint (WF) of a country, with the UK as an example. We trace, quantify and map the UK’s direct and indirect water needs and assess the ‘imported water risk’ by evaluating the sustainability of the water consumption in the source regions. In addition, we assess the efficiency of the water consumption in source areas in order to identify the room for water savings. We find that half of the UK’s global blue WF—the direct and indirect consumption of ground- and surface water resources behind all commodities consumed in the UK—is located in places where the blue WF exceeds the maximum sustainable blue WF. About 55% of the unsustainable part of the UK’s blue WF is located in six countries: Spain (14%), USA (11%), Pakistan (10%), India (7%), Iran (6%), and South Africa (6%). Our analysis further shows that about half of the global consumptive WF of the UK’s direct and indirect crop consumption is inefficient, which means that consumptive WFs exceed specified WF benchmark levels. About 37% of the inefficient part of the UK’s consumptive WF is located in six countries: Indonesia (7%), Ghana (7%), India (7%), Brazil (6%), Spain (5%), and Argentina (5%). In some source countries, like Pakistan, Iran, Spain, USA and Egypt, unsustainable and inefficient blue water consumption coincide. We find that, by lowering overall consumptive WFs to benchmark levels, the global blue WF of UK crop consumption could be reduced by 19%. We discuss four strategies to mitigate imported water risk: become more self-sufficient in food; diversify the import of water-intensive commodities, favouring

    Prioritizing corresponds to the process of selecting and managing health needs identified after diagnosing the community's health needs and assets. Recently, the health needs assessment has been reinforced with the community perspective, providing multiple benefits: it sensitizes and empowers the community about their health, encourages mutual support among its members and promotes their importance by making them responsible for the process of improving their own reality. The objective of this paper is to describe the prioritization of Barcelona Salut als Barris, a community health strategy led by the Barcelona Public Health Agency to promote equity in health in the most disadvantaged neighborhoods of the city.

    The collection of 152 samples from the upper sublittoral zone along the rocky coasts of Catalonia (Northwestern Mediterranean) was carried out in 1999 in order to test the suitability of littoral communities to be used as indicators of water quality in the frame of the European Water Framework Directive. Detrended correspondence analysis were performed to distinguish between different communities and to relate communities composition to water quality. Samples collected in reference sites were included in the analysis. Mediterranean rocky shore communities situated in the upper sublittoral zone can be used as indicators of the water quality: there is a gradient from high to bad status that comprises from dense Cystoseira mediterranea forests to green algae dominated communities. The geographical patterns in the distribution of these communities show that the best areas are situated in the Northern coast, where tourism is the main economic resource of the area, and the worst area is situated close to the metropolitan zone of Barcelona with high population and industrial development. Thus, Mediterranean sublittoral rocky shore communities are useful indicators of water quality and multivariate analysis are a suitable statistical tool for the assessment of the ecological status.

    Full Text Available This article is based on the research I did for my doctoral thesis about voluntarily single motherhood in Barcelona (Catalonia, Spain. It is an anthropological approach to the appearance and the development of voluntarily single motherhood, which is when a woman becomes a mother through adoption or conception previously planned without partner. Within a framework of study carried out from October 2001 to October 2007 in the Barcelona Metropolitan Area, my research is based on in-depth interviews with twelve women from April 2002 to April 2006. The aim of the paper is to understand why women in Barcelona choose to be voluntarily single mothers. The purpose is to point out that the voluntarily single motherhood is a new way of understanding between women and men, resulting from the progressive changes in their respective gender roles. This anthropological research is grounded in a full vital process: from the personal decision of the women to become single mothers to the daily interaction with their children.

    Residential plumbing is critical for the health and safety of populations worldwide. A case study was conducted to understand fixture water use, drinking water quality and their possible link, in a newly plumbed residential green building. Water use and water quality were monitored at four in-building locations from September 2015 through December 2015. Once the home was fully inhabited average water stagnation periods were shortest at the 2nd floor hot fixture (90 percentile of 0.6-1.2 h). The maximum water stagnation time was 72.0 h. Bacteria and organic carbon levels increased inside the plumbing system compared to the municipal tap water entering the building. A greater amount of bacteria was detected in hot water samples (6-74,002 gene copy number/mL) compared to cold water (2-597 gene copy number/mL). This suggested that hot water plumbing promoted greater microbial growth. The basement fixture brass needle valve may have caused maximum Zn (5.9 mg/L), Fe (4.1 mg/L), and Pb (23 μg/L) levels compared to other fixture water samples (Zn ≤ 2.1 mg/L, Fe ≤ 0.5 mg/L and Pb ≤ 8 μg/L). At the basement fixture, where the least amount of water use events occurred (cold: 60-105, hot: 21-69 event/month) compared to the other fixtures in the building (cold: 145-856, hot: 326-2230 event/month), greater organic carbon, bacteria, and heavy metal levels were detected. Different fixture use patterns resulted in disparate water quality within a single-family home. The greatest drinking water quality changes were detected at the least frequently used fixture.

    Full Text Available Overcoming Poverty Trap : The Case of  Water & Sanitation in Indonesia. Poverty trap is a cycle in which poor individuals exhibit low health quality due to malnutrition and limited access to health related facilities. Poor health causes low productivity which eventually cycles back to low income. Indonesia significantly reduced poverty from 15.6% in 1990 to 3.3% in 2010. However, this achievement is not conveyed equally across regions. Using data form RAND Corporation, estimations showed that access to sanitation and clean water play a crucial role in improving one’s health quality.   Keywords: poverty trap, productivity, income, health facility.

    Climate change poses huge challenges for public health, and cities are at the forefront of this process. The purpose of this paper is to present the issues climate change poses for public health in the city of Barcelona, how they are being addressed, and what are the current major challenges, trying to contribute to the development of a baseline understanding of the status of adaptation in cities from a public health perspective. The major issues related to climate change faced by the city are common to other urban centers in a Mediterranean climate: heat waves, water availability and quality, air quality, and diseases transmitted by vectors, and all are reviewed in detail with empirical data. They are not a potential threat for the future, but have actually challenged the city services and infrastructure over the last years, requiring sustainable responses and rigorous planning. © The Author(s) 2016.

  10. Perceptions of water scarcity: The case of Genadendal and outstations

    Science.gov (United States)

    Noemdoe, S.; Jonker, L.; Swatuk, L. A.

    The water resources management regime has shifted from one focusing almost exclusively on augmenting supply to one where ensuring access, equity and sustainability are an integral part of process. It is widely recognized that South Africa will face water scarcity in the near future. But ‘scarcity’, as we show in our case study, is a relative concept. This paper interrogates perceptions of scarcity in the small South African rural community of Greater Genadendal. Using a wide variety of data, we explore the intersection between poverty alleviation and adequate water supply. The results show that notwithstanding sufficient water being available, the community experiences what Mehta [Mehta, L., 2001. The manufacture of popular perceptions of scarcity: dams and water-related narratives in Gujarat, India. World Development 29 (12), 2025-2041] calls ‘manufactured scarcity’. This is due to inadequate infrastructure, institutional incapacity and a history of political inequality. In the case of Greater Genadendal, these forms of scarcity are present simultaneously leading to a very complex situation. Overcoming these types of scarcity, however, require more than just new infrastructure. They require socio-economic and socio-political types of intervention that target the bases for manufactured scarcity: abiding poverty and socio-inequality. However, there appears to be a lack of social capital, in particular the trust that would enable government and local people to work together for improved livelihoods and sustainable water supplies. Joint resource rehabilitation activities may be one way of building social capital and moving toward IWRM in the study area.

  11. Water balance analysis for efficient water allocation in agriculture. A case study: Balta Brailei, Romania

    Balta Brailei is one of the largest agriculture area in the Danube floodplain, located in SE of Romania. An impressive irrigation system, that covered about 53.500 ha and transferred water from the Danube River, was carried out in the period 1960-1980. Even if the water resources for agriculture in this area cover in most of the cases the volumes required by irrigation water users, the irrigation infrastructure issues as the position of the pumping stations against the river levels hinder the use of the water during low flows periods. An efficient optimization of water allocation in agriculture could avoid periods with water deficit in the irrigation systems. Hydrological processes are essentials in describing the mass and energy exchanges in the atmosphere-plant-soil system. Furthermore, the hydrological regime in this area is very dynamic with many feedback mechanisms between the various parts of the surface and subsurface water regimes. Agricultural crops depend on capillary rise from the shallow groundwater table and irrigation. For an effective optimization of irrigation water in Balta Brailei, we propose to analyse the water balance taking into consideration the water movement into the root zone and the influence of the Danube river, irrigation channel system and the shallow aquifer by combining the soil water balance model CRITERIA and GMS hydrogeological model. CRITERIA model is used for simulating water movement into the soil, while GMS model is used for simulating the shallow groundwater level variation. The understanding of the complex feedbacks between atmosphere, crops and the various parts of the surface and subsurface water regimes in the Balta Brailei will bring more insights for predicting crop water need and water resources for irrigation and it will represent the basis for implementing Moses Platform in this specific area. Moses Platform is a GIS based system devoted to water procurement and management agencies to facilitate planning of

    The presentation is directed to the description of the actual situation and relevant information of the geodetic infrastructure of Ibiza and Barcelona sites for sea level determination and contribution to regional sea level rise. Time series are being analysed for mean sea level variations www.puertos.es. .In the framework of a Spanish Space Project, the instrumentation of sea level measurements has been improved by providing the Barcelona site with a radar tide gauge Datamar 2000C from Geonica s.l. near an acoustic tide gauge. Puertos del Estado installed in 2007 a MIROS radar tide gauge and the Barcelona Harbour Authority a GPS referente station in the roof of the new Control Tower situated in the Energy Pier. The radar sensor is over the water surface, on a L-shaped structure which elevates it a few meters above the quay shelf. 1-min data are transmitted to the ENAGAS Control Center by cable and then sent each 1 min to Puertos del Estado by e-mail. There is a GPS station Leica Geosystems GRX1200 GG Pro and antenna 1202. Precision levelling has been made several times in the last two years because the tower is founded in reclaimed land. The measured settlement rate is about 1cm/year that may be could mask the values registered by the tide gauge. A description of the actual infrastructure at Ibiza harbour at Marina de Botafoch, is presented and its applications to sea level monitoring and altimeter calibration in support of the main CGPS at Ibiza harbour. It is described the geometrical precision levelling made in June 2013 between the radar tide gauge and the GPS station. In particular, the CGPS located at Ibiza harbour is essential for its application to the marine campaign Baleares 2013, near Ibiza island. The main objective is to determine the altimeter bias for Jason-2, about 9:09 UTC September 15, 2013, and Saral/AltiKa, about 05:30 UTC September 16, UTC.

    Full Text Available Barcelona is a city, which through the democratization of public space in the second half of the seventies, developed with a noticeable intention of balancing the public and private. The municipalities’ efforts were focused towards the planification and regeneration of dilapidated spaces and the construction of new structures for public benefit. However, since 2007 new phenomena have come to light that emphasise urban problems in which public interests become less important than private investment initiatives. New market priorities, together with tourism and myriad immigration have caused an “expropriation” of the city from its inhabitants.

    The water supply system in Timisoara Municipality is insured with about 25-30 % of the water demand from wells. The underground water headed to the water treatment plant in order to ensure equal distribution and pressure to consumers. The treatment plants used are Urseni and Ronaţ, near Timisoara, in Timis County. In Timisoara groundwater represents an alternative source for water supply and complementary to the surface water source. The present paper presents a case study with proposal and solutions for rehabilitation /equipment /modernization/ automation of water drilling in order to ensure that the entire system can be monitored and controlled remotely through SCADA (Supervisory control and data acquisition) system. The data collected from the field are designed for online efficiency monitoring regarding the energy consumption and water flow intake, performance indicators such as specific energy consumption KW/m3 and also in order to create a hydraulically system of the operating area to track the behavior of aquifers in time regarding the quality and quantity aspects.

  17. Efficiency and acceptance of new water allocation rules - The case of an agricultural water users association.

    2017-12-01

    Water scarcity is one of the major environmental problems in Southern Europe. High levels of water stress and increasing frequency of droughts, along with a greater environmental protection, make it necessary to design water management strategies that are allocative efficient and balance supply and demand. When functioning markets cannot be developed, the allocation rules proposed in the literature of social choice have been recognized as a suitable alternative. However, the application of new water allocation rules can be impaired by a lack of acceptance and implementation problems. This paper examines these obstacles for the case of an agricultural water users association (WUA), situated in the basin of the River Ebro, in relation to the governance structure and collective decision rule of the WUA. It analyzes the extent to which the gains and losses of the farmers affect their acceptance, and examines conditions for building agreements with side payments that provide incentives for the majority of the farmers to form part of a possible agreement. The results show that the uniform and sequential rules improve the allocative efficiency under normal conditions compared to the status quo and the sequential rule even in the case of droughts. In the presence of side payments this rule is likely to be accepted and has only an insignificant impact on distributional inequality. Copyright © 2017 Elsevier B.V. All rights reserved.

    Continental shelves are recognized to play a key role in the biogeochemical cycle of carbon, linking terrestrial and marine carbon reservoirs. In this study we investigate the physical and biogeochemical processes that control the source, transport and fate of organic carbon (OC) in the continental shelf off Barcelona city, in the NW Mediterranean Sea. Surface sediment samples were collected from depths of 10-40 m during late summer and autumn 2012. Grain size and biogeochemical parameters such as OC, its stable isotope δ13C, total nitrogen (TN) and OC/TN ratios were analysed in size-fractionated sediments. The influence of environmental factors over the study area was determined using hydrological and oceanographic time series, together with video images of the Barcelona coast line and nearshore region. We have found a wide range of OC contents, from 0.13 to 8.68%, depending on water depth and sediment particle size. The highest OC concentration was always found in the clay fraction (63 μm) that contained terrestrial plant debris. Wave activity, discharge of the Besòs River and the "Espigó" de Ginebra; outfall were the main mechanisms controlling the sorting of sediments by their grain size and thus the distribution of OC in the inner shelf off Barcelona. In addition, we observed that the organic matter in clay particles was progressively degraded seawards, probably because these particles remain suspended in the water column much more time compared to those that are heavier and, therefore, they are exposed for longer time periods to oxygenated conditions. Both OC/TN ratios and δ13C values found suggest that the organic matter preserved was predominantly land supplied.

    2015-04-01

    Due to climate change, extreme weather conditions such as droughts may have an increasing impact on irrigated agriculture. To cope with the higher demand of water, a new decision support framework is developed which focuses on an integrated management of both irrigation water supply and demand. For modeling the regional water demand, local stochastic water demand functions are used which are derived from optimized agronomic response on farms scale. These functions take into account different soil types, crops, stochastically generated climate scenarios considering different economic conditions, e.g., variable and fixed costs. This generic approach enables the consideration of both multiple crops at farm scale as well as of the aggregated response to water pricing at a regional scale for full and deficit irrigation systems. Within the SAPHIR (SAxonian Platform for High Performance IRrigation) project a prototype of a decision support system is developed and applied for a case study in Saxony which helps to evaluate combined water supply and demand management policies on a regional level.

This study evaluates the effectiveness of intervention with community health workers (CHW to improve contact tracing among immigrants. Methods The study included all TB cases detected by the Barcelona TB Program from 2000 to 2005 and compared a period without CHW intervention (2000-2002 to a period with CHW intervention (2003-2005. The influence on contact tracing of sex, age, hospital of diagnosis, district of residence, birthplace, HIV, homeless and CHW intervention was analysed by logistic regression. Odds ratio (OR and 95% confidence intervals (CI were calculated. Results 960 foreign born TB cases were detected, 388 in the intervention period. Contact tracing was performed on 65,7% of 201 smear-positive cases during the pre-intervention period compared to 81.6% of 152 smear-positive TB cases during the intervention period (p Conclusions The effectiveness of contact tracing for TB control in areas with high immigration can be improved by incorporating CHWs who act as translators, cultural mediators and facilitators who accompany cases and contacts through treatment and follow-up.

  6. The tragedy of the water commons: the case of the Lower Orange water management area

    Full Text Available In the human environment there is a tendency to refer to resources, such as land and water which do not specifically belong to any single individual, as the ‘commons’. Garret Hardin wrote his famous paper called: “The Tragedy of the Commons” in which he highlighted the problem inhabitants of the world face regarding the growing population and depletion of natural resources. He proposed that limits must be placed on the liberal use of natural resources, which usually involve some kind of legislation. South Africa, as a semi-arid country, needs to manage the water as a commons to ensure that all inhabitants of the country have access to safe drinking water as instructed by the Constitution of the Republic of South Africa Act No. 108 of 1996 and subsequently preserved in the National Water Act No 36 of 1998. The significance of Hardin’s theory to South Africa becomes evident in the necessity of the mentioned acts, which involve the establishment of Catchment Management Agencies (CMAs and Water User Associations (WUAs. These institutions must ensure the involvement of all stakeholders and water users to manage the resource optimally. Establishing these institutions, however, proved to be difficult and their efficiency questioned, thus illustrating a “tragedy within the tragedy”. This article considers the case of the Lower Orange Catchment Management Agency and the Upington Islands Water User Association in the //Khara Hais local municipality, to illustrate the thus far failing efforts taken by this region to manage the water resource.

  7. Online modelling of water distribution systems: a UK case study

    Directory of Open Access Journals (Sweden)

    J. Machell

    2010-03-01

    Full Text Available Hydraulic simulation models of water distribution networks are routinely used for operational investigations and network design purposes. However, their full potential is often never realised because, in the majority of cases, they have been calibrated with data collected manually from the field during a single historic time period and, as such, reflect the network operational conditions that were prevalent at that time, and they are then applied as part of a reactive, desktop investigation. In order to use a hydraulic model to assist proactive distribution network management its element asset information must be up to date and it should be able to access current network information to drive simulations. Historically this advance has been restricted by the high cost of collecting and transferring the necessary field measurements. However, recent innovation and cost reductions associated with data transfer is resulting in collection of data from increasing numbers of sensors in water supply systems, and automatic transfer of the data to point of use. This means engineers potentially have access to a constant stream of current network data that enables a new era of "on-line" modelling that can be used to continually assess standards of service compliance for pressure and reduce the impact of network events, such as mains bursts, on customers. A case study is presented here that shows how an online modelling system can give timely warning of changes from normal network operation, providing capacity to minimise customer impact.

    A life cycle assessment (LCA) is performed in this study in order to evaluate the environmental implications of the management of the fermentable fraction of waste in the Barcelona Metropolitan Area (BMA), comparing the present management system with the system proposed for the future. The energy and water consumption were quantified, as well as the used area and the emissions to the atmosphere and water. The software TRACI was used in order to assess the potential impact on the categories of acidification, eutrophication, toxicity and harm to the human health (under the criteria of cancer, non-cancer and pollutants), global warming, depletion of the ozone layer, formation of photochemical smog, water use, land use and fossil fuel use. The results show that the management system proposed for the future reduces 7 out of the 12 potential impacts analyzed, due mainly to the change in the technology of landfill (baling-wrapping landfill). However, this system requires of further research to assess the impacts on a long term. The worst option for biowaste management is the traditional landfill, based on the multibarrier concept. The results of this work suggest that the future biowaste management system is better in environmental terms than the present system. (author)

    Acute hepatitis A is transmitted mainly via the faecal-oral route and/or contaminated aliment. Furthermore, several outbreaks in the men who have sex with men (MSM) population classified hepatitis A as a sexually transmitted disease (STD). We aimed to clarify an ongoing hepatitis A outbreak in Barcelona with respect to patients' characteristics and viral phylogenetic analysis. We prospectively analyzed 46 cases of hepatitis A infection that were registered in our hospital between January and June 2017. We evaluated demographics data, risk factors, presenting symptoms, sexual orientation, comorbidities and further STD infections. The phylogenetic correlation of the current circulating viruses among them and other hepatitis A strains was assessed by sequencing of the VP1/P2A region. Most patients were male (44, 96%) with median age 33.5 years (range 28-50). Thirty-one (67%) were MSM and 18 (39%) required hospitalization. Molecular phylogenetic analyses revealed that all patients were infected by hepatitis A subgenotype IA strains. Moreover, current strains comprised 3 distinct clusters, previously reported in ongoing outbreaks in the United Kingdom, Berlin and the Netherlands. However, these strains were phylogenetically diverse to those previously reported in Barcelona metropolitan region. Ongoing hepatitis A outbreak in Barcelona affects primarily the MSM community and is phylogenetically linked to current hepatitis A outbreaks described in other European countries. As a result of the high admission rate, these outbreaks may impact the admission pattern of referral liver units. Control measures, for example vaccinations programs tailored to the MSM community, must be taken to control further spreading. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Numerous studies showing statistically significant associations between environmental noise and adverse health effects already exist for short-term (over one day at most) and long-term (over a year or more) noise exposure, both for morbidity and (albeit to a lesser extent) mortality. Recently, several studies have shown this association to be independent from confounders, mainly those of air pollutants. However, what has not been addressed is the problem of misalignment (i.e. the exposure data locations and health outcomes have different spatial locations). Without any explicit control of such misalignment inference is seriously compromised. Our objective is to assess the long-term effects of traffic noise on mortality in the city of Barcelona (Spain) during 2004-2007. We take into account the control of confounding, for both air pollution and socioeconomic factors at a contextual level and, in particular, we explicitly address the problem of misalignment. We employed a case-control design with individual data. We used deaths resulting from myocardial infarction, hypertension, or Type II diabetes mellitus in Barcelona between 2004 and 2007 as cases for the study, while for controls we used deaths (likewise in Barcelona and over the same period of time) resulting from AIDS or external causes (e.g. accidental falls, accidental poisoning by psychotropic drugs, drugs of abuse, suicide and self-harm, or injuries resulting from motor vehicle accidents). The controls were matched with the cases by sex and age. We used the annual average equivalent A-weighted sound pressure levels for daytime (7-21h), evening-time (21-23h) and night-time (23-7h), and controlled for the following confounders: i) air pollutants (NO2, PM10 and benzene), ii) material deprivation (at a census tract level) and iii) land use and other spatial variables. We explicitly controlled for heterogeneity (uneven distribution of both response and environmental exposures within an area), spatial dependency

  14. Water resources for urban water and food security: the case of megacity Hong Kong

    2017-04-01

    The extent to which urban dwellers consume resources is key on the path to reaching global SDGs. One of these resources is water, which is consumed in a direct and indirect way by city inhabitants, to achieve water and food security within city borders. In this study, we quantify the water resources required to provide these two essential securities for megacity Hong Kong. During the last years, this city has made large investments to make its urban water supply system more water efficient and sustainable. As such, its municipal water abstraction - often defined as direct water use - has decreased from 355 litres per capita per day (l/cap/d) in 2005 to 326 l/cap/d in 2013. Due to its political history, Hong Kong is unique in the world in data availability on urban food consumption. It is therefore the ideal case study to show typical urban food consumption behaviour and its related indirect water use. The current average diet in Hong Kong is very different to the average Chinese diet. It is characterised by a high intake of water intensive products like animal products and sugar, leading to a food related indirect water use or water footprint (WFcons) of 4727 l/cap/d. According to recommendations from the Chinese Nutrition Society for a healthy diet, the intake of some product groups should be increased (vegetables and fruit) and of other product groups reduced (sugar, crop oils, meat and animal fats). This would result in a reduction of the WFcons of 40% to 2852 l/cap/d. Especially the reduced intake of meat (including offals) from currently 126 kg per capita per year (kg/cap/yr) to the recommended value 27 kg/cap/yr would result in a substantial WFcons reduction. Meat consumption in Hong Kong is extremely high. A pesco-vegetarian diet would result in a reduction of 49% (to 2398 l/cap/d) and a vegetarian diet in a 53% (to 2224 l/cap/d) reduction. Hong Kong citizens can thus save a lot of water by looking at their indirect water use, through a change in their diet

    Full Text Available This work attempts to assess the history of two of the most important prisons of the Franco’s dictactorship, Ventas and Les Corts, corresponding to the most populated Spanish cities, Madrid and Barcelona. We start from the background of the female imprisonment in Spain, branded by an special stamp with the keynote of influence of religious agents, at least until the Republican reforms of 1931. At the same time, we stress the impact of the «civilizatory breach» as a result of the civil war and immediate postwar, in terms of massive imprisonment and spreading of death sentences even among women. Finally, this essay deals with the making up of an specific prisoner culture, closely politicized and distinguished from the male one, the memory of which would be transmitted over the following decades by means of the stories of the political female prisoners.

    Full Text Available THE SOCIAL AND TEMPORAL COSTS OF MOBILITY IN INDUSTRIAL DISTRICTS. THE CASE OF THE BARCELONA METROPOLITAN REGION. Since the 1960s, there has been an increasing tendency towards relocating industrial activities to areas located in the urban peripheries that are destined for that specific purpose. The private car has become the main means of connecting these production spaces with the rest of the urban fabric. This connectivity option entails high mobility costs, which can be analytically divided into operative, environmental, social and temporal costs. This article focuses on both the social and the temporal costs of the journeys to and from industrial estates located in two peripheral municipalities of the Barcelona Metropolitan Region. The main findings of the research highlight the important role played by territorial organisation and transport planning in reducing these costs, as well as their consequent usefulness when adequately embedded into social policies.

Esta discusión teórica da lugar a un marco de evaluación de las prácticas de participación que se aplica al análisis de las 11 experiencias vigentes de presupuestos participativos en la provincia de Barcelona. El análisis pone en evidencia los límites de este tipo de prácticas de participación, los cuales están relacionados con tres factores principales: su posición institucional periférica; el escaso margen de decisión que se concede a la ciudadanía; y la escasa movilización social. Sin embargo, los casos analizados obtienen buenos resultados en dos aspectos importantes: el impacto de las propuestas ciudadanas en la toma de decisiones públicas y la transformación de las actitudes políticas, técnicas y ciudadanas hacia la participación. El marco de evaluación propuesto nos ayuda a identificar ámbitos críticos de mejora de los procesos participativos y de fortalecimiento de su capacidad transformadora.

    2014-01-01

    Finding alternative resources to secure or increase water availability is a key issue in most urban areas. This makes the research of alternative and local water resources of increasing importance. In the context of political tension with its main water provider (Malaysia), Singapore has been implementing a comprehensive water policy for some decades, which relies on water demand management and local water resource mobilisation in order to reach water self-sufficiency by 2060. The production of water from alternative resources through seawater desalination or water reclamation implies energy consumptive technologies such as reverse osmosis. In the context of increasing energy costs and high primary energy dependency, this water self-sufficiency objective is likely to be an important challenge for Singapore. The aim of this paper is to quantify the long-term impact of Singapore's water policy on the national electricity bill and to investigate the impact of Singapore's projects to reduce its water energy footprint. We estimate that 2.0% of the Singaporean electricity demand is already dedicated to water and wastewater treatment processes. If its water-energy footprint dramatically increases in the coming decades, ambitious research projects may buffer the energy cost of water self-sufficiency.

    2014-03-01

    The water footprint by the Water Footprint Network (WF) is an ambitious tool for measuring human appropriation and promoting sustainable use of fresh water. Using recent case studies and examples from water-abundant Fennoscandia, we consider whether it is an appropriate tool for evaluating the water use of forestry and forest-based products. We show that aggregating catchment level water consumption over a product life cycle does not consider fresh water as a renewable resource and is inconsistent with the principles of the hydrologic cycle. Currently, the WF assumes that all evapotranspiration (ET) from forests is a human appropriation of water although ET from managed forests in Fennoscandia is indistinguishable from that of unmanaged forests. We suggest that ET should not be included in the water footprint of rain-fed forestry and forest-based products. Tools for sustainable water management should always contextualize water use and water impacts with local water availability and environmental sensitivity.

  2. Introducing a water quality index for assessing water for irrigation purposes: A case study of the Ghezel Ozan River.

    Rivers are one of the main water resources for agricultural, drinking, environmental and industrial use. Water quality indices can and have been used to identify threats to water quality along a stream and contribute to better water resources management. There are many water quality indices for the assessment and use of surface water for drinking purposes. However, there is no well-established index for the assessment and direct use of river water for irrigation purposes. The aim of this study was to adopt the framework of the National Sanitation Foundation Water Quality Index (NSFWQI) and, with adjustments, apply it in a way which will conform to irrigation water quality requirements. To accomplish this, the NSFWQI parameters for drinking water use were amended to include water quality parameters suitable for irrigation. For each selected parameter, an individual weighting chart was generated according to the FAO 29 guideline. The NSFWQI formula was then used to calculate a final index value, and for each parameter an acceptable range in this value was determined. The new index was then applied to the Ghezel Ozan River in Iran as a case study. A forty five year record of water quality data (1966 to 2010) was collected from four hydrometery stations along the river. Water quality parameters including Na + , Cl - , pH, HCO - 3, EC, SAR and TDS were employed for water quality analysis using the adjusted NSFWQI formula. The results of this case study showed variation in water quality from the upstream to downstream ends of the river. Consistent monitoring of the river water quality and the establishment of a long term management plan were recommended for the protection of this valuable water resource.

    The Annual Congress of the European Society of Cardiology (ESC) was held in Barcelona from 30th August to 3rd September 2014. More than 30,300 attendees from around the world shared the latest original research, including 27 clinical Hot Line studies, 12 basic science Hot Lines, 15 clinical trial updates, 19 registry studies, and 4,597 abstracts. Many important issues were presented, including novel treatment strategies for heart failure, acute coronary syndrome, interventional treatment for structural heart disease, renal denervation, novel anticoagulant therapies, atrial fibrillation and so on. In addition, 5 new ESC clinical practice guidelines (ie, myocardial revascularization, non-cardiac surgery, acute pulmonary embolism, hypertrophic cardiomyopathy, and aortic disease) were launched. It should be noted that Japan has recently been ranked in the top position in terms of the number of abstract submissions. Based on these activities, the ESC Congress has been recognized as the dominant scientific and educational forum for healthcare professionals in cardiology. We report the highlights and several key presentations of the ESC Congress 2014. The scientific activities and growing contributions of Japanese cardiologists or cardiovascular surgeons enhance the favorable relationship between the ESC and the Japanese Circulation Society.

  10. Chlorinated organic pesticides in marketed food: Barcelona, 2001-06

    This paper reports concentration levels of 22 chlorinated organic compounds (both primary compounds and metabolites) in food marketed in the city of Barcelona (Catalonia, Spain) in 2001-06. Samples included meat products, fish and seafood, eggs, milk and dairy, vegetal oils, cereal products and derivates, vegetables, fresh fruits, dry fruits, spices, formula and baby food, tea and wine. Levels of chlorinated organic compounds were determined by gas chromatography with selective detectors: electron capture (ECD), flame photometric (FPD) and confirmation with mass-spectrometry. Chlorinated organic pesticides were detected in 7 of the 1,484 samples analyzed in the 2001-06 period (0.5%): 1 dairy product, 1 fruit, 1 olive oil and 4 vegetables. Specific pesticides detected are lindane and endosulfan {alpha}, {beta} or sulphate. A decrease in both the proportion of samples with detectable residues and in the variety of chlorinated pesticides found is visible when comparing these results with those of the previous 1989-2000 period. These results suggest the gradual disappearance of regulated chlorinated organic pesticides as a consequence of the growing worldwide implementation of current regulatory agreements.

  11. Das Modell Barcelona – Partizipation, Protest und Postpolitik

    Full Text Available Das ‚Modell Barcelona‘ steht für eine Stadtplanung, bei der unterschiedliche Akteur_innen vermeintlich vorbildlich in Entscheidungs- und Entwicklungsprozesse einbezogen sind. Die heutigen formellen Beteiligungsformen werden dabei meist als in der Tradition der nachbarschaftlichen Proteste in den 1970er Jahren stehend gesehen und die zunehmende Formalisierung von Bürger_innenbeteiligung wird als Prozess der Demokratisierung verstanden. In meinem Beitrag wird der Zusammenhang zwischen partizipativen Verfahren und Demokratie grundlegend hinterfragt und dem traditionellen Demokratiebegriff ein emanzipatorisches Verständnis von Demokratie gegenübergestellt, das sich an Theorien der poststrukturalistischen politischen Philosophie orientiert. Anhand einer empirischen Fallstudie zum aktuellen Widerstand gegen den Umbau des Hafengebiets Port Vell in Barcelona wird gezeigt, inwiefern formale Partizipationsmöglichkeiten die Teilhabe der Bevölkerung nicht nur nicht unterstützen, sondern letztlich einschränken oder verhindern. Abschließend wird diskutiert, ob nicht formalisierte Proteste eine Alternative zu formellen Partizipationsverfahren darstellen können.

Acuden a centros terapéuticos gratuitos, aunque pagan por la organización del viaje unos 500 euros. Son jóvenes entre 18 y 30 años y mantienen el contacto con sus familiares. Conocen los riesgos de transmisión de enfermedades, pero suelen reutilizar las jeringas. Es alta la prevalencia de hepatitis C (92% y B (62% y menor la de infección por el VIH (19%. Si no abandonan las drogas, el retorno es un fracaso y tienen dificultades para proseguir los tratamientos con metadona o antirretrovirales. La respuesta asistencial ha de adecuarse a sus necesidades. Se debe procurar la mediación cultural y la información en los lugares de origen, supervisar los centros terapéuticos y diseñar alternativas a los abandonos. Hay que desarrollar la colaboración internacional, estimular programas de disminución de riesgos derivados del consumo y evitar que del tratamiento se haga un comercio.From May 1999 to May 2001, we made contact with injecting drug users from Eastern Europe in the healthcare and prevention service of the Red Cross (servicio de atención y prevención sociosanitaria [SAPS] in Barcelona (Spain.

    The development of an evaluation protocol for assessing the scientific contribution and the impact on medical care of the sabbatical leaves granted in a large Spanish teaching hospital. The sabbatical leaves for all faculty staff of the Hospital Clínic i Provincial of Barcelona (HCPB) were analyzed since 1980 trough 1991. The scientific production analysis was done according to the impact factor (IF) score of the Science Citation Index. Descriptive statistical techniques as well as parametric and non-parametric tests were used for comparisons. A total of 52 sabbatical leaves was analyzed of all 60 leaves granted (87%). Mean duration of the leave was 7.94 +/- 3.86 months. The scientific production includes 89 original articles published in peer-reviewed medical journals, with a total score of 300.82 IF points (mean score: 5.78 +/- 7.12 IF points by leave). There were significant differences in the mean duration, number of papers published and IF points score by sabbatical leave between the Medicine, Surgery and Other Departments. In 16 cases (31%) there was a professional promotion following the sabbatical leave and in 20 cases (39%) an academic promotion. In 27 cases (60%) there was no promotion after the leave. Most of the faculty staff physicians (96%) are still employed in the same institution, and believe that the sabbatical leave has significantly contributed to their promotion (67%). A high percentage (94%) has also been able to develop afterwards the methods and techniques learned during the sabbatical leave. The experience of the Hospital Clinic of Barcelona in granting sabbatical leaves has been highly positive. The scientific performance of the individuals on leave is high. Our institution has been able to add and develop most of the techniques and methods learned overseas. The future of the sabbatical leaves in other Spanish Universities and Hospitals should be regarded as a high priority target. The performance of these leaves is supported by its

    Unerupted supernumerary teeth, depending on the morphology, number and distribution can give rise to various alterations in the eruption and development of those permanent teeth to which they are related. We aimed to make an epidemiological and descriptive study of the clinical characteristics of patients in Barcelona, their surgical treatment and how said treatment was hindered. A descriptive study including 113 supernumerary teeth from 79 healthy pediatric patients between 5 and 19 years of age, which underwent surgery in our hospital during a 2 year period (May 2005 / May 2007), taking into account the variables of personal data, gender, age, location, number, morphology, position-axis, radiological study, surgical treatment, related pathologies, and surgical complications. Male patients (51) were more frequently affected than female (28) patients mainly within the central incisors-mesiodens (53.16%), in which the unique form (68.52%) predominates in conoid morphology (69.62%). Surgical treatment was done by palatal/lingual extraction (49.37%), with few surgical complications (only 1 case of post-surgical bleeding). Incidence in supernumerary teeth is higher among male patients (ratio M:F of 1.82:1). They are most frequently located in the maxilla (82%), specifically, in the premaxilla (77%). Most cases presented only one supernumerary tooth (68.5%) and, in multiple cases, the premolar region is predominant. The conoid shape is the commonest morphology (69.62%). Surgical extraction, was done by palatal/lingual in 49.37% of the cases, as opposed to the vestibular approach in 45.57%.

    Several epidemiological studies have reported associations between increases in summer temperatures and risks of premature mortality. The quantitative implications of predicted future increases in summer temperature, however, have not been extensively characterized. We have quantified these effects for the four main cities in Catalonia, Spain (Barcelona, Tarragona, Lleida, Girona). We first used case-crossover analysis to estimate the association between temperature and mortality for each of these cities for the period 1983 to 2006. These exposure-response (ER) functions were then combined with local measures of current and projected changes in population, mortality and temperature for the years 2025 and 2050. Predicted daily mean temperatures were based on the A1B greenhouse gas emission, "business-as-usual" scenario simulations derived from the ENSEMBLES project. Several different ER functions were examined and significant associations between temperature and mortality were observed for all four cities. For these four cities, the age-specific piecewise linear model predicts 520 (95%CI 340, 720) additional annual deaths attributable to the change in temperature in 2025 relative to the average from the baseline period of 1960-1990. For 2050, the estimate increases to 1,610 deaths per year during the warm season. For Catalonia as a whole, the point estimates for those two years are 720 and 2,330 deaths per year, respectively, or about 2 and 3% of the warm season. In comparing these predicted impacts with current causes of mortality, they clearly represent significant burdens to public health in Catalonia.

  16. Biomedical practices from a patient perspective. Experiences of Polish female migrants in Barcelona, Berlin and London.

    2016-08-01

    This paper focuses on the diversity in patients' experience of bio-medicine and contrasts it with the normative view characteristic of health professionals. Ethnographic fieldwork among Polish migrant women in London, Barcelona and Berlin included interviews about their experiences with local healthcare and health professionals. Themes drawn from the narratives are differences between the cities in terms of communication between patients and health professionals, respect for patients' choices and dignity, attitudes to pregnancy and birth (different levels of medicalization), and paediatric care. It is argued that patients continuously negotiate among their own views and expectations based on previous experiences and knowledge from personal communication; internet forums and publications; and the offer of medical services in the countries of their settlement. Patients experience pluralism of therapeutic traditions within and outside bio-medicine. In turn, representatives of bio-medicine are rarely aware of other medical practices and beliefs and this leads to various misunderstandings. By highlighting the pluralism of medical practices in European countries and the increasing mobility of patients, this case study has useful implications for medical anthropologists and health professionals in a broader Western context, such as raising sensitivity to different communication strategies and a diversity of curing traditions and expectations.

    The cost of municipal water treatment due to diminished water quality represents an important component of the societal costs of water pollution. Here the chemical costs of municipal water treatment are expressed as a function of raw surface water quality. Data are used for a 3-year period for 12 water treatment plants in Texas. Results show that when regional raw water contamination is present, the chemical cost of water treatment is increased by 95 per million gallons (per 3785 m3) from a base of 75. A 1% increase in turbidity is shown to increase chemical costs by 0.25%.

    As part of a case-control study of community-acquired Legionnaires' disease, several factors related to residential water distribution systems and public drinking water systems were studied in the homes of 124 patients with community-acquired Legionnaire's disease and in the homes of 354 controls. The presence of water reservoirs and hot water tanks was studied in residential systems. Factors such as deficient chlorine levels, pipe repairs and other work, water flow interruptions, the use of alternative water sources, inadequate cleaning operations in public water reservoirs, and the position of the home within the public network (and whether this location constituted an endpoint) were studied in public water supply systems. Levels of legionellae in domestic water samples were also measured. Although the use of water reservoirs and hot water tanks promotes colonization by legionellae in residential systems, none of the variables studied seems to increase the incidence of community-acquired Legionnaires' disease.

    2015-01-01

    Climate change is expected to bring increases in average global temperatures (1.4°C-5.8°C [34.52°F-42.44°F] by 2100) and precipitation levels to varying degrees around the globe. The availability and quality of water will be severely affected, and public health threats from the lack of this valuable resource will be great unless water-scarce nations are able to adapt. Saudi Arabia provides a good example of how the climate and unsustainable human activity go hand in hand in creating stress on and depleting water resources, and an example for adaptation and mitigation. A search of the English literature addressing climate change, water scarcity, human health, and related topics was conducted using online resources and databases accessed through the University at Albany, State University of New York library web page. Water scarcity, which encompasses both water availability and water quality, is an important indicator of health. Beyond drinking, water supply is intimately linked to food security, sanitation, and hygiene, which are primary contributors to the global burden of disease. Poor and disadvantaged populations are the ones who will suffer most from the negative effects of climate change on water supply and associated human health issues. Examples of adaptation and mitigation measures that can help reduce the strain on conventional water resources (surface waters and fossil aquifers or groundwater) include desalination, wastewater recycling and reuse, and outsourcing food items or "virtual water trade." These are strategies being used by Saudi Arabia, a country that is water poor primarily due to decades of irresponsible irrigation practices. The human and environmental health risks associated with these adaptation measures are examined. Finally, strategies to protect human health through international collaboration and the importance of these efforts are discussed. International, multidisciplinary cooperation and collaboration will be needed to promote

    Background. The Barcelona Music Reward Questionnaire (BMRQ) questionnaire investigates the main facets of music experience that could explain the variance observed in how people experience reward associated with music. Currently, only English and Spanish versions of this questionnaire are available. The objective of this study is to validate a French version of the BMRQ. Methods. The original BMRQ was translated and adapted into an international French version. The questionnaire was then administered through an online survey aimed at adults aged over 18 years who were fluent in French. Statistical analyses were performed and compared to the original English and Spanish version for validation purposes. Results. A total of 1,027 participants completed the questionnaire. Most responses were obtained from France (89.4%). Analyses revealed that congruence values between the rotated loading matrix and the ideal loading matrix ranged between 0.88 and 0.96. Factor reliabilities of subscales (i.e., Musical Seeking, Emotion Evocation, Mood Regulation, Social Reward and Sensory-Motor) also ranged between 0.88 and 0.96. In addition, reliability of the overall factor score (i.e., Music reward) was 0.91. Finally, the internal consistency of the overall scale was 0.85. The factorial structure obtained in the French translation was similar to that of the original Spanish and English samples. Conclusion. The French version of the BMRQ appears valid and reliable. Potential applications of the BMRQ include its use as a valuable tool in music reward and emotion research, whether in healthy individuals or in patients suffering from a wide variety of cognitive, neurologic and auditory disorders.

    2017-12-01

    Heat-related effects on mortality have been widely analyzed using maximum and minimum temperatures as exposure variables. Nevertheless, the main focus is usually on the former with the minimum temperature being limited in use as far as human health effects are concerned. Therefore, new thermal indices were used in this research to describe the duration of night hours with air temperatures higher than the 95% percentile of the minimum temperature (hot night hours) and intensity as the summation of these air temperatures in degrees (hot night degrees). An exposure-response relationship between mortality due to natural, respiratory, and cardiovascular causes and summer night temperatures was assessed using data from the Barcelona region between 2003 and 2013. The non-linear relationship between the exposure and response variables was modeled using a distributed lag non-linear model. The estimated associations for both exposure variables and mortality shows a relationship with high and medium values that persist significantly up to a lag of 1-2 days. In mortality due to natural causes, an increase of 1.1% per 10% (CI95% 0.6-1.5) for hot night hours and 5.8% per each 10° (CI95% 3.5-8.2%) for hot night degrees is observed. The effects of hot night hours reach their maximum with 100% and lead to an increase by 9.2% (CI95% 5.3-13.1%). The hourly description of night heat effects reduced to a single indicator in duration and intensity is a new approach and shows a different perspective and significant heat-related effects on human health.

    Recent features of a car wash wastewater reclamation system and results from a full-scale car wash wastewater treatment and recycling process are reported. This upcoming technology comprises a new flocculation-column flotation process, sand filtration, and a final chlorination. A water usage and savings audit (22 weeks) showed that almost 70% reclamation was possible, and fewer than 40 L of fresh water per wash were needed. Wastewater and reclaimed water were characterized by monitoring chemical, physicochemical and biological parameters. Results were discussed in terms of aesthetic quality (water clarification and odour), health (pathological) and chemical (corrosion and scaling) risks. A microbiological risk model was applied and the Escherichia coli proposed criterion for car wash reclaimed water is 200 CFU 100 mL(-1). It is believed that the discussions on car wash wastewater reclamation criteria may assist institutions to create laws in Brazil and elsewhere.

    Water scarcity is not just a problem of its own right (hydrological drought) but cascades the hydro-economic system to create problems for crop growth and livestock (agricultural drought) and thus for wellbeing and economic productivity (economic drought). One of these cascades is the impact of reduced water quantity on water quality as a result of non-point source pollutant concentration in water bodies such as rivers, lakes and wetlands. This paper investigates the impact of seasonal water shortages on the quality of supplied water to urban centres with a view to better understanding how land use management can reduce dry-season pollutant spikes. We apply a widely used spatial hydrological model (WaterWorld) and its water quality index (the human footprint on water quality, HFWQ) to examine to what extent HFWQ of water flowing into urban water intakes is affected by flow seasonality and by typical "dry year" events. A global analysis shows trends across climatic and land use gradients and is followed by a regional analysis of the Magdalena basin in Colombia: a large basin with 79% of the countries population and a mixture of intensively farmed and protected lands along a seasonality gradient from South to North. The Magdalena is a case study basin of the EartH2Observe project.

    The real amount of drinking water available per capita is a topic of great interest for human health and the economic and political management of resources. The global market of bottled drinking water, for instance, has shown exponential growth in the last twenty years, mainly due to reductions in production costs and investment in promotion. This paper aims to evaluate how much freshwater is actually consumed when water is drunk in Italy, which can be considered a mature bottled-water market. A Water Footprint (WF) calculation was used to compare the alternatives: bottled and tap water. Six Italian brands of water sold in PET bottles were inventoried, analysed and compared with the public tap water of the city of Siena, as representative of the Italian context. Results showed that more than 3 L of water were needed to provide consumers with 1.50 L of drinking water. In particular, a volume of 1.50 L of PET-bottled water required an extra virtual volume of 1.93 L of water while an extra 2.13 L was necessary to supply the same volume of tap water. These values had very different composition and origin. The WF of tap water was mainly due to losses of water during pipeline distribution and usage, while WF of bottled water was greatly influenced by the production of plastic materials. When the contribution of cooling water was added to the calculation, the WF of bottled water rose from 3.43 to 6.92 L. Different strategies to reduce total water footprint are discussed.

    To estimate the health and economic benefits that would result from two scenarios of improved air quality in 57 municipalities of the metropolitan area of Barcelona. We used attributable fractions and life tables to quantify the benefits for selected health outcomes, based on published concentration-response functions and economic unit values. The mean weighted concentration of PM(10) for the study population was estimated through concentration surface maps developed by the local government. The annual mean health benefits of reducing the mean PM(10) exposure estimated for the population in the study area (50microg/m(3)) to the annual mean value recommended by the World Health Organization (20microg/m(3)) were estimated to be 3,500 fewer deaths (representing an average increase in life expectancy of 14 months), 1,800 fewer hospitalizations for cardio-respiratory diseases, 5,100 fewer cases of chronic bronchitis among adults, 31,100 fewer cases of acute bronchitis among children, and 54,000 fewer asthma attacks among children and adults. The mean total monetary benefits were estimated to be 6,400 million euros per year. Reducing PM(10) to comply with the current European Union regulatory annual mean level (40microg/m(3)) would yield approximately one third of these benefits. This study shows that reducing air pollution in the metropolitan area of Barcelona would result in substantial health and economic benefits. The benefits are probably underestimated due to the assumptions made in this study. Assessment of the health impact of local air pollution is a useful tool in public health.

    Health professionals and authorities strive to cope with heterogeneous data, services, and statistical models to support decision making on public health. Sophisticated analysis and distributed processing capabilities over geocoded epidemiological data are seen as driving factors to speed up control and decision making in these health risk situations. In this context, recent Web technologies and standards-based web services deployed on geospatial information infrastructures have rapidly become an efficient way to access, share, process, and visualize geocoded health-related information. Data used on this study is based on Tuberculosis (TB) cases registered in Barcelona city during 2009. Residential addresses are geocoded and loaded into a spatial database that acts as a backend database. The web-based application architecture and geoprocessing web services are designed according to the Representational State Transfer (REST) principles. These web processing services produce spatial density maps against the backend database. The results are focused on the use of the proposed web-based application to the analysis of TB cases in Barcelona. The application produces spatial density maps to ease the monitoring and decision making process by health professionals. We also include a discussion of how spatial density maps may be useful for health practitioners in such contexts. In this paper, we developed web-based client application and a set of geoprocessing web services to support specific health-spatial requirements. Spatial density maps of TB incidence were generated to help health professionals in analysis and decision-making tasks. The combined use of geographic information tools, map viewers, and geoprocessing services leads to interesting possibilities in handling health data in a spatial manner. In particular, the use of spatial density maps has been effective to identify the most affected areas and its spatial impact. This study is an attempt to demonstrate how web

    Full Text Available Abstract Background Early diagnosis of HIV infection can prevent morbidity and mortality as well as reduce HIV transmission. The aim of the present study was to assess prevalence, describe trends and identify factors associated with late presentation of HIV infection in Barcelona (Spain during the period 2001-09. Methods Demographic and epidemiological characteristics of cases reported to the Barcelona HIV surveillance system were analysed. Late presentation was defined for individuals with a CD4 count below 350 cells/ml upon HIV diagnosis or diagnosis of AIDS within 3 months of HIV diagnosis. Multivariate logistic regression were used to identify predictors of late presentation. Results Of the 2,938 newly diagnosed HIV-infected individuals, 2,507 (85,3% had either a CD4 cell count or an AIDS diagnosis available. A total of 1,139 (55.6% of the 2,507 studied cases over these nine years were late presenters varying from 48% among men who have sex with men to 70% among heterosexual men. The proportion of late presentation was 62.7% in 2001-2003, 51.9% in 2004-2005, 52.6% in 2006-2007 and 52.1% in 2008-2009. A decrease over time only was observed between 2001-2003 and 2004-2005 (p = 0.001 but remained constant thereafter (p = 0.9. Independent risk factors for late presentation were older age at diagnosis (p Conclusion Late presentation of HIV is still too frequent in all transmission groups in spite of a strong commitment with HIV prevention in our city. It is necessary to develop interventions that increase HIV testing and facilitate earlier entry into HIV care.

    Full Text Available The presence of a high prevalence of bronchial hyperresponsiveness and asthma-like symptoms in swimmers has been reported. But, attacks of asthma which is related to chlorinized water is rare. Chlorine, a strong oxidizing agent, is an important toxic gas that the swimmer can breath during swimming and a worker can exposed to chlorine while he or she was using water with chlorine at home. We describe a persistent increase in nonspecific bronchial hyperresponsiveness following chronic exposure to strong respiratory irritant with chlorinized water in two subjects with no past history of asthma or atopy. We conclude that airway hyperresponsiveness can develop or increase after chronic inhalation of high concentrations of irritants such as chlorinized water an indoor irritant factor and that these changes may be prolonged.

    1993-01-01

    The geologic evidence for a water-rich Mars has been reviewed, and it has been concluded that it is consistent with an outgassed inventory of H2O equivalent to global ocean 0.5-1 km deep. The most persuasive support for this conclusion comes from the martian outflow channels, whose distribution, size, and range of ages, suggests that a significant body of ground water was present on Mars throughout much of its geologic history. In this abstract, the thermodynamic implications of the outflow channels are considered. The results of this analysis suggest that if the outflow channels were carved by the discharge of ground water in diffusive and thermodynamic equilibrium with the overlying frozen crust, it implies a minimum planetary inventory of water in excess of 300 m. However, if the global inventory of ground water on Mars at the time of outflow channel formation was as high as the 500 m estimate of other researchers, then the total inventory of water on Mars could well exceed 750 m.

    In present study we investigate the formation and evolution of oceanic wakes generated by obstacle of a real island shape (in our case - Madeira island) but without consideration of bathymetry around it. Numerical simulations using Regional Ocean Modeling System (ROMS) are presented. ROMS is a free-surface, terrain-following, primitive equations ocean model (Shchepetkin and McWilliams, 2005). Numerical models are often used to study the formation and evolution of the leeward, mesoscale and sub-mesoscale flows around of islands (Dietrich et al., 1996; Dong et al., 2007; Heywood et al., 1996). Madeira archipelago is a group of deep-sea islands located at Northeast Atlantic at about 33°N, 17°W. The biggest island of the archipelago is Madeira Island with about 50 km in east-west and 20 km in north-south direction. Its obstruction to the incoming oceanic and atmospheric flows induces leeward wake instabilities. This phenomena is observed using remote sensing and field data (Caldeira et al., 2002). We use the similar methodology to study Madeira island wakes problem as it was presented at Dong et al., 2007. The main difference between their study and ours is that they carried out experiences with an idealized cylindrical obstacle and we are using an island with its real shape at the surface and with vertical sides. The island was centered in a geostrophic channel like configuration with a prescribed surface intensified meridional (southward) inflow at the upstream boundary (i.e., our study is dedicated to the wakes, generated at the eastern and western part of Madeira Island). Eastern and Western channel boundaries were set to slippery-tangential and zero normal conditions, whereas boundaries around the island were set to zero-normal and no-slip flow. A clamped condition with a sponge layer was applied at the southern outflow boundary for outgoing current and density profile. The initial conditions for the entire domain were set equal to the upstream boundary

    Joep F Schyns

    Full Text Available A Water Footprint Assessment is carried out for Morocco, mapping the water footprint of different activities at river basin and monthly scale, distinguishing between surface- and groundwater. The paper aims to demonstrate the added value of detailed analysis of the human water footprint within a country and thorough assessment of the virtual water flows leaving and entering a country for formulating national water policy. Green, blue and grey water footprint estimates and virtual water flows are mainly derived from a previous grid-based (5 × 5 arc minute global study for the period 1996-2005. These estimates are placed in the context of monthly natural runoff and waste assimilation capacity per river basin derived from Moroccan data sources. The study finds that: (i evaporation from storage reservoirs is the second largest form of blue water consumption in Morocco, after irrigated crop production; (ii Morocco's water and land resources are mainly used to produce relatively low-value (in US$/m3 and US$/ha crops such as cereals, olives and almonds; (iii most of the virtual water export from Morocco relates to the export of products with a relatively low economic water productivity (in US$/m3; (iv blue water scarcity on a monthly scale is severe in all river basins and pressure on groundwater resources by abstractions and nitrate pollution is considerable in most basins; (v the estimated potential water savings by partial relocation of crops to basins where they consume less water and by reducing water footprints of crops down to benchmark levels are significant compared to demand reducing and supply increasing measures considered in Morocco's national water strategy.

    Solar domestic hot water (SDHW) systems have been installed on buildings for decades, but because of relatively high costs they have not achieved significant market penetration in most of the country. As more buildings move towards zero net energy consumption, however, many designers and developers are looking more closely at SDHW. In multifamily buildings especially, SDHW may be more practical for several reasons: (1) When designing for zero net energy consumption, solar water heating may be part of the lowest cost approach to meet water heating loads. (2.) Because of better scale, SDHW systems in multifamily buildings cost significantly less per dwelling than in single-family homes. (3) Many low-load buildings are moving away from fossil fuels entirely. SDHW savings are substantially greater when displacing electric resistance water heating. (4) In addition to federal tax incentives, some states have substantial financial incentives that dramatically reduce the costs (or increase the benefits) of SDHW systems in multifamily buildings. With support form the U.S. DOE Building America program, the Consortium for Advanced Residential Buildings (CARB) worked with a developer in western Massachusetts to evaluate a SDHW system on a 12-unit apartment building. Olive Street Development completed construction in spring of 2014, and CARB has been monitoring performance of the water heating systems since May 2014.

    Full Text Available The Water Safety Plan (WSP approach is an iterative method focused on analyzing the risks of water contamination in a drinking water supply system, from catchment to consumer, in order to protect human health. This approach is aimed at identifying and drastically reducing water contamination in the entire drinking water system, through the identification and mitigation or, if possible, elimination of all factors that may cause a chemical, physical, microbiological and radiological risk for water. This study developed a proposal of WSP for the drinking water supply system (DWSS of Mortara, Italy, in order to understand which are the preliminary evaluation aspects to be considered in the elaboration of a WSP. The DWSS of Mortara (a town of 15,500 inhabitants, located in northern Italy consists of three drinking water treatment plants (DWTPs, considering the following main contaminants: arsenic, iron, manganese and ammonia. Potential hazardous events and associated hazards were identified in each part of the water supply system. The risk assessment was carried out following the semi quantitative approach. The WSP proposal for Mortara was very useful not only as a risk mitigation approach, but also as a cost-effective tool for water suppliers. Furthermore, this approach will reduce public health risk, ensure a better compliance of water quality parameters with regulatory requirements, increase confidence of consumers and municipal authorities, and improve resource management due to intervention planning. Further, some new control measures are proposed by the WSP team within this work.

    Full Text Available Aquaponic systems are integrated systems that combine fish farming and different types of plants. It involves a dynamic interaction between fish plants and bacteria. Fish and plants are dependent the equilibrium of dissolved nutrients and water quality. Only by striking a balance between dissolved nutrients and water quality we can achieve a large production of plants and healthy fish. Thus, control of water quality in an aquaponic system is essential in order to obtain performance in raising fish and plants. The experiment was conducted in the laboratory of Fisheries and Aquaculture of the Faculty of Animal Science of the University of Agronomic Sciences and Veterinary Medicine of Bucharest within a period of 30 days. The system used for the experiment was designed and developed in the laboratory mentioned above. The plant used for water treatment in the system was basil (Ocimum basilicum. Fish species grown in the system was culture carp (Cyprinus carpio. Indicators measured to assess water quality in the system were: temperature, pH, dissolved oxygen, total ammonia, nitrites, nitrates and phosphates. The values determined pH 7.4-7.6, dissolved oxygen 8-10 mg / l, NH4 0.05-05 mg/ l, NO2 0.1-3.2 mg / l, NO3 0-80 mg / l, 0.02-0.3 mg, PO4 0.02-0.3 mg/l were not too high. In conclusion it was demonstrated that water quality in the aquaponic system studied is propitious to the growth and welfare of fish the registered values are not to be harmful.

  13. Does Integrated Water Resources Management Support Institutional Change? The Case of Water Policy Reform in Israel

    Directory of Open Access Journals (Sweden)

    Itay Fischhendler

    2010-03-01

    Full Text Available Many international efforts have been made to encourage integrated water resources management through recommendations from both the academic and the aid and development sectors. Recently, it has been argued that integrated water resources management can help foster better adaptation of management and policy responses to emerging water crises. Nevertheless, few empirical studies have assessed how this type of management works in practice and what an integrated water management system implies for institutional adaptation and change. Our assessment of the Israeli water sector provides one view of how they can be shaped by an integrated structure in the water sector. Our analysis of recent efforts to adapt Israel's water management system to new conditions and uncertainties reveals that the interconnectedness of the system and the consensus decision-making process, led by a dominant actor who coordinates and sets the policy agenda, tends to increase the complexity of negotiations. In addition, the physical integration of water management leads to sunk costs of large-scale physical infrastructure. Both these factors create a path dependency that empowers players who receive benefits from maintaining the existing system. This impedes institutional reform of the water management system and suggests that integrated water resources management creates policy and management continuity that may only be amenable to incremental changes. In contrast, real adaptation that requires reversibility and the ability to change management strategies in response to new information or monitoring of specific management outcomes.

    2014-12-01

    The question of "equity." is a vague and relative term in any event, criteria for equity are particularly difficult to determine in water conflicts, where international water law is ambiguous and often contradictory, and no mechanism exists to enforce principles which are agreed-upon. The aim of this study is using the water footprints as a concept to be an indicator or a measuring tool for the Equitable Utilization of shared water resources. Herein Egypt and Ethiopia water resources conflicts in Nile River Basin were selected as a case study. To achieve this study; water footprints, international virtual water flows and water footprint of national consumption of Egypt and Ethiopia has been analyzed. In this study, some indictors of equitable utilization has been gained for example; Egypt water footprint per capita is 1385 CM/yr/cap while in Ethiopia is 1167 CM/yr/cap, Egypt water footprint related to the national consumption is 95.15 BCM/yr, while in Ethiopia is 77.63 BCM/yr, and the external water footprints of Egypt is 28.5%, while in Ethiopia is 2.3% of the national consumption water footprint. The most important conclusion of this study is; natural, social, environmental and economical aspects should be taken into account when considering the water footprints as an effective measurable tool to assess the equable utilization of shared water resources, moreover the water footprints should be calculated using a real data and there is a necessity to establishing a global water footprints benchmarks for commodities as a reference.

    2006-01-01

    As communities grow, greater demands are placed on water supplies, wastewater services, and the electricity needed to power the growing water services infrastructure. Water is also a critical resource for thermoelectric power plants. Future population growth in the United States is therefore expected to heighten competition for water resources. Many parts of the United States with increasing water stresses also have significant wind energy resources. Wind power is the fastest-growing electric generation source in the United States and is decreasing in cost to be competitive with thermoelectric generation. Wind energy can offer communities in water-stressed areas the option of economically meeting increasing energy needs without increasing demands on valuable water resources. Wind energy can also provide targeted energy production to serve critical local water-system needs. The research presented in this report describes a systematic assessment of the potential for wind power to support water utility operation, with the objective to identify promising technical applications and water utility case study opportunities. The first section describes the current situation that municipal providers face with respect to energy and water. The second section describes the progress that wind technologies have made in recent years to become a cost-effective electricity source. The third section describes the analysis employed to assess potential for wind power in support of water service providers, as well as two case studies. The report concludes with results and recommendations.

En el caso de Barcelona, las carreras atléticas gozaron de un notable auge entre la población, erigiéndose en una manifestación deportiva característica de este periodo. Con su carácter popular, estas carreras se impregnaron de elementos constitutivos del momento, tales como la libertad o la democracia. Este artículo se centra en el análisis de las carreras populares en Barcelona como muestra de las transformaciones que vivió el fenómeno deportivo durante la transición política y, a su vez, como fenómeno a partir de la cual comprender algunos de los elementos constitutivos de la realidad social y política del momento. La metodología utilizada ha consistido en el análisis interpretativo de fuentes secundarias y hemerográficas. En este sentido, se pueden diferenciar dos periodos. El primero (1975-1978 permitió la aparición de las primeras carreras con un carácter participativo y festivo, mientras que durante el periodo 1979-1982 se vivió su auge y consolidación.

    2017-06-01

    A questionnaire survey was conducted in order to assess residents' perceptions of water quality for drinking and recreational purposes in a mid-sized city in northcentral West Virginia. Two logistic regression analyses were conducted in order to investigate the factors that influence bottle use and filter use. Results show that 37% of respondents primarily use bottled water and that 58% use a household filter when drinking from the tap. Respondents with lower levels of environmental concern, education levels, and lower organoleptic perceptions were most likely to perceive health risks from tap water consumption, and were most likely to use bottled water. Income, age, and organoleptic perceptions were predictors of water filter use among respondents. Clean water for recreational purposes was not found to be significant with either of these models. Our results demonstrate that bottle use and filter use are explained differently. We argue that more education and better communication about local tap water quality would decrease the use of bottled water.

    Full Text Available Drought and water shortage effects are normally exacerbated due to collateral impacts on water quality, since low streamflow affects water quality in rivers and water uses depend on it. One of the most common problems during drought conditions is maintaining a good water quality while securing the water supply to demands. This research analyses the case of the Turia River Water Resource System located in Eastern Spain. Its main water demand comes as urban demand from Valencia City, which intake is located in the final stretch of the river, where streamflow may become very low during droughts. As a result, during drought conditions concentrations of pathogens and other contaminants increase, compromising the water supply to Valencia City. In order to define possible solutions for the above-mentioned problem, we have developed an integrated model for simulating water management and water quality in the Turia River Basin to propose solutions for water quality problems under water scarcity. For this purpose, the Decision Support System Shell AQUATOOL has been used. The results demonstrate the importance of applying environmental flows as a measure of reducing pollutant's concentration depending on the evolution of a drought event and the state of the water resources system.

    Rivers are one of the most environmentally vulnerable sources for contamination. Since the rivers pass through the cities, industrial and agricultural centers, these have been considered as place to dispose the sewages. This issue is more important when the river is one of the main sources of water supplying for drinking, agricultural and industrial utilizations. The goal of the present study was assessing the physicochemical characteristics of the Tireh River water. The Tireh River is the main river in the Karkheh catchment in the Iran. To this end, 14 sampling stations for measuring the physicochemical properties of Tireh River along the two main cities (Borujerd and Dorud) were measured. The results showed that (except SO4) Mg, Ca and other anions and cations have concentrations under WHO standard limitation. Almost all samples have suitable conditions for drinking with regard to the WHO standard and in comparison with agricultural standard (FAO Standard), and the potential of water is suitable for irrigation purposes. According to Wilcox diagram, 78 % of samples were at the C3-S1 and 21.5 % were at C2-S1 classes. The piper diagram shows that most of samples are bicarbonate and calcic facies.

  10. Everyday politics, social practices and movement networks: daily life in Barcelona's social centres.

    Yates, Luke

    2015-06-01

    The relations between everyday life and political participation are of interest for much contemporary social science. Yet studies of social movement protest still pay disproportionate attention to moments of mobilization, and to movements with clear organizational boundaries, tactics and goals. Exceptions have explored collective identity, 'free spaces' and prefigurative politics, but such processes are framed as important only in accounting for movements in abeyance, or in explaining movement persistence. This article focuses on the social practices taking place in and around social movement spaces, showing that political meanings, knowledge and alternative forms of social organization are continually being developed and cultivated. Social centres in Barcelona, Spain, autonomous political spaces hosting cultural and educational events, protest campaigns and alternative living arrangements, are used as empirical case studies. Daily practices of food provisioning, distributing space and dividing labour are politicized and politicizing as they unfold and develop over time and through diverse networks around social centres. Following Melucci, such latent processes set the conditions for social movements and mobilization to occur. However, they not only underpin mobilization, but are themselves politically expressive and prefigurative, with multiple layers of latency and visibility identifiable in performances of practices. The variety of political forms - adversarial, expressive, theoretical, and routinized everyday practices, allow diverse identities, materialities and meanings to overlap in movement spaces, and help explain networks of mutual support between loosely knit networks of activists and non-activists. An approach which focuses on practices and networks rather than mobilization and collective actors, it is argued, helps show how everyday life and political protest are mutually constitutive. © London School of Economics and Political Science 2014.

  11. Medicine, cinema and literature: A teaching experiment at the Universitat Autónoma de Barcelona

    Full Text Available             In Spain, it is commonly held that medical students spend the entire time of their degree courses obsessed with the MIR (Post-graduate Medical Training/ Medical Residency exam and, when they have sat and passed this, the health system itself together with excessive professional activity foster   what is tantamount to a “hyperspecialisation”, in many cases in detriment to “learning to read” the patient as a complete entity. Upon exercising their profession, physicians should understand patients in their entirety since medicine –when considered as ethical humanism- fails if the patient is merely slotted into the “specialist” pigeon-hole. At the Teaching Unit of the Hospital Universitari Germans Trias i Pujol of the Universitat Autónoma de Barcelona we were prompted to incorporate a subject in the syllabus that would allow students to “both read and see medicine” to an extent far beyond the diagnostic level, that would  provide them with a broader view of diseases, and one that that would become an emotional complement to the material studied in their degree course (and as a direct consequence, to their future profession, which tends to be excessively “biologistic”. What, then, could be better than literature and the cinema to teach students to “read and see medicine”? From previous knowledge that we had culled from other university programs, this would not only be a novel subject per se but should also offer a completely different learning model from traditional teaching contents in the field. This would thus approach the situation in other degree courses, such as in business studies, where similar subjects and models are used.

    Trypanosoma cruzi, the causative agent of Chagas disease, is divided into six Discrete Typing Units (DTUs): TcI-TcVI. We aimed to identify T. cruzi DTUs in Latin-American migrants in the Barcelona area (Spain) and to assess different molecular typing approaches for the characterization of T. cruzi genotypes. Seventy-five peripheral blood samples were analyzed by two real-time PCR methods (qPCR) based on satellite DNA (SatDNA) and kinetoplastid DNA (kDNA). The 20 samples testing positive in both methods, all belonging to Bolivian individuals, were submitted to DTU characterization using two PCR-based flowcharts: multiplex qPCR using TaqMan probes (MTq-PCR), and conventional PCR. These samples were also studied by sequencing the SatDNA and classified as type I (TcI/III), type II (TcII/IV) and type I/II hybrid (TcV/VI). Ten out of the 20 samples gave positive results in the flowcharts: TcV (5 samples), TcII/V/VI (3) and mixed infections by TcV plus TcII (1) and TcV plus TcII/VI (1). By SatDNA sequencing, we classified the 20 samples, 19 as type I/II and one as type I. The most frequent DTU identified by both flowcharts, and suggested by SatDNA sequencing in the remaining samples with low parasitic loads, TcV, is common in Bolivia and predominant in peripheral blood. The mixed infection by TcV-TcII was detected for the first time simultaneously in Bolivian migrants. PCR-based flowcharts are very useful to characterize DTUs during acute infection. SatDNA sequence analysis cannot discriminate T. cruzi populations at the level of a single DTU but it enabled us to increase the number of characterized cases in chronically infected patients.

    2002-12-01

    The XIII International AIDS Conference in Durban, South Africa in July 2000 focused worldwide attention on the problem of accessing treatments in developing countries. In the interim, thanks to the work of activists - from demonstrations to court cases, and from acts of public courage by people living with HIV/AIDS to ongoing lobbying of politicians and trade negotiators - some very significant developments have occurred. But the reality is that the vast majority of people living with HIV/AIDS still lack access to affordable, quality medicines. This article, a summary of a paper presented at "Putting Third First: Vaccines, Access to Treatments and the Law," a satellite meeting held at Barcelona on 5 July 2002 and organized by the Canadian HIV/AIDS Legal Network, the AIDS Law Project, South Africa, and the Lawyers Collective HIV/AIDS Unit, India, explores three approaches for improving access. In the first part, Richard Elliott provides an overview of the state of the right to health as embodied in international human rights law; comments on the experience to date in litigating claims to the right to health; and identifies potential strategies activists can adopt to advance recognition of the right to health. In the second part, Sharan Parmar and Vivek Divan describe price-control and drug-financing mechanisms used by industrialized countries to increase the affordability of medicines; and discuss how some of these mechanisms could be adapted for use in developing countries. Finally, Jonathan Berger describes the use of litigation in the courts by the Treatment Action Campaign in South Africa.

    The main aquifer of the Llobregat Delta (Barcelona, Spain) is affected by seawater intrusion processes since 1970. The Catalan Water Agency is currently promoting several actions of enhanced aquifer recharge, including the construction of a positive hydraulic barrier in order to stop the advance of the seawater intrusion. Such a positive hydraulic barrier works by injecting reclaimed water in 14 wells. This is the first time that a project of this type is performed in Spain, and it is also pioneer in Europe. The positive hydraulic barrier produces the rise of the groundwater head near the coast and avoids seawater penetration inland. The injected reclaimed water comes from the WWTP of the Baix Llobregat after passing through several treatments (ultrafiltration, osmosis and disinfection). The pilot phase of the project has been working during the last 2 years, showing highly positive results. Substantial improvement of the groundwater quality has been observed in wells surrounding the injection points and no clogging has been appeared. The second phase of the project is currently under construction. (Author) 13 refs.

    Full Text Available Iran’s focus on food self-sufficiency has led to an emphasis on increasing water volumes available for irrigation with little attention to water use efficiency, and no attention at all to the role of consumption and trade. To better understand the development of water consumption in relation to food production, consumption, and trade, we carried out the first comprehensive water footprint assessment (WFA for Iran, for the period 1980–2010, and estimated the water saving per province associated with interprovincial and international crop trade. Based on the AquaCrop model, we estimated the green and blue water footprint (WF related to both the production and consumption of 26 crops, per year and on a daily basis, for 30 provinces of Iran. We find that, in the period 1980–2010, crop production increased by 175%, the total WF of crop production by 122%, and the blue WF by 20%. The national population grew by 92%, and the crop consumption per capita by 20%, resulting in a 130% increase in total food consumption and a 110% increase in the total WF of national crop consumption. In 2010, 26% of the total water consumption in the semi-arid region served the production of crops for export to other regions within Iran (mainly cereals or abroad (mainly fruits and nuts. Iran’s interprovincial virtual water trade grew by a factor of 1.6, which was mainly due to increased interprovincial trade in cereals, nuts, and fruits. Current Iranian food and water policy could be enriched by reducing the WFs of crop production to certain benchmark levels per crop and climatic region and aligning cropping patterns to spatial differences in water availability and productivities, and by paying due attention to the increasing food consumption per capita in Iran.

    The accidental inhalation by two people of tritiated water is described. One person incorporated approximately 35 GBq (1 Ci) and was treated by forced diuresis. Her committed effective dose equivalent was approx. 0.4 Sv. The diuresis procedure and physiological monitoring of the patient is described. The other person incorporated only about 1 GBq (0.03 Ci) and accelerated his excretion of tritium by extra drinking. The clearance rates of tritium-in-urine are presented for both subjects and are used to estimate committed effective dose equivalents. These are compared with values from cytogenetic dosimetry derived from repeated blood sampling.

    Full Text Available Abstract Background The objective of this study was to assess trends in cancer mortality by educational level in Barcelona from 1992 to 2003. Methods The study population comprised Barcelona inhabitants aged 20 years or older. Data on cancer deaths were supplied by the system of information on mortality. Educational level was obtained from the municipal census. Age-standardized rates by educational level were calculated. We also fitted Poisson regression models to estimate the relative index of inequality (RII and the Slope Index of Inequalities (SII. All were calculated for each sex and period (1992–1994, 1995–1997, 1998–2000, and 2001–2003. Results Cancer mortality was higher in men and women with lower educational level throughout the study period. Less-schooled men had higher mortality by stomach, mouth and pharynx, oesophagus, larynx and lung cancer. In women, there were educational inequalities for cervix uteri, liver and colon cancer. Inequalities of overall and specific types of cancer mortality remained stable in Barcelona; although a slight reduction was observed for some cancers. Conclusion This study has identified those cancer types presenting the greatest inequalities between men and women in recent years and shown that in Barcelona there is a stable trend in inequalities in the burden of cancer.

  9. Impact of Water Availability on Regional Power System Operations - A Case Study of ERCOT

    2015-12-01

    Impact of water availability on regional power system operations - A case study of ERCOT Thermal power plants are the largest single source of water withdrawals in the United States, mainly for cooling purposes. The amount of water that is required for cooling is highly dependent on a number of factors including the generation technologies being used, the temperature of the input water, and the total electricity load in the system. During summer months, many of these factors coincide to greatly increase the demand for water in a power system. Electricity demand typically reaches its annual peak when temperatures are high due to increased air conditioning loads. Ambient water temperatures also increase, meaning that greater quantities of water are required to provide the same amount of cooling at thermal generation plants. Finally, water availability is generally constrained due to seasonal effects and potential droughts. This raises concerns that water scarcity may lead to forced de-rating at some power plants during periods of peak demand, resulting in a more vulnerable and less reliable energy system. While increasing attention has recently been given to the inexorable link between water and energy, most commercial power models do not explicitly account for water use when optimizing system operation. We apply the AURORAxmp power modeling software to a case study analysis of the ERCOT power system to determine the water requirements of the system during periods of peak power demand. We then analyze water availability by location and time to identify potential supply shortages, which may reduce actual power generation availability. These data are fed back into the power systems model and specific generation units are de-rated as necessitated by water constraints. We then analyze these results to determine how the optimal generation mix, system reliability, and wholesale electricity prices may be affected by when the ERCOT power system is operated under water

  10. Getting into hot water Problematizing hot water service demand: The case of Old Cairo

    Science.gov (United States)

    Culhane, Thomas Henry

    This dissertation analyzes hot water demand and service infrastructure in two neighboring but culturally distinct communities of the urban poor in the inner-city area of central Cairo. The communities are the Historic Islamic Cairo neighborhood of Darb Al Ahmar at the foot of Al-Azhar park, and the Zurayib neighborhood of Manshiyat Nasser where the Coptic Zabaleen Recyclers live. The study focuses on the demand side of the hot water issue and involves consideration of built-environment infrastructures providing piped water, electricity, bottled gas, sewage, and the support structures (wiring and plumbing) for consumer durables (appliances such as hot water heaters, stoves, refrigerators, air conditioners) as well as water pumps and water storage tanks. The study asks the questions "How do poor communities in Cairo value hot water" and "How do cost, infrastructure and cultural preferences affect which attributes of hot water service are most highly preferred?". To answer these questions household surveys based primarily on the World Bank LSMS modules were administered by professional survey teams from Darb Al Ahmar's Aga Khan Trust for Culture and the Zabaleen's local NGO "Spirit of Youth" in their adjacent conununities in and surrounding historic Cairo. In total 463 valid surveys were collected, (231 from Darb Al Ahmar, 232 from the Zabaleen). The surveys included a contingent valuation question to explore Willingness to Pay for improved hot water service; the surveys queried household assets as proxies for income. The dissertation's findings reveal that one quarter of the residents of Darb Al Ahmar and two-thirds of the residents of Manshiyet Nasser's Zabaleen lack conventional water heating service. Instead they employ various types of stoves and self-built contraptions to heat water, usually incurring considerable risk and opportunity costs. However the thesis explores the notion that this is rational "satisficing" behavior; despite the shortcomings of such self

    Urban Health Equity Assessment and Response Tool (HEART) is a tool developed by the World Health Organization whose objective is to provide evidence on urban health inequalities so as to help to decide the best interventions aimed to promote urban health equity. The aim of this paper is to describe the experience of implementing Urban HEART in Barcelona city, both the adaptation of Urban HEART to the city of Barcelona, its use as a means of identifying and monitoring health inequalities among city neighbourhoods, and the difficulties and barriers encountered throughout the process. Although ASPB public health technicians participated in the Urban HEART Advisory Group, had large experience in health inequalities analysis and research and showed interest in implementing the tool, it was not until 2015, when the city council was governed by a new left-wing party for which reducing health inequalities was a priority that Urban HEART could be used. A provisional matrix was developed, including both health and health determinant indicators, which allowed to show how some neighbourhoods in the city systematically fare worse for most of the indicators while others systematically fare better. It also allowed to identify 18 neighbourhoods-those which fared worse in most indicators-which were considered a priority for intervention, which entered the Health in the Barcelona Neighbourhoods programme and the Neighbourhoods Plan. This provisional version was reviewed and improved by the Urban HEART Barcelona Working Group. Technicians with experience in public health and/or in indicator and database management were asked to indicate suitability and relevance from a list of potential indicators. The definitive Urban HEART Barcelona version included 15 indicators from the five Urban HEART domains and improved the previous version in several requirements. Several barriers were encountered, such as having to estimate indicators in scarcely populated areas or finding adequate

    2011-02-01

    Full Text Available Human use of freshwater resources has placed enormous stress on aquatic ecosystems in many regions of the world. At one time, this was considered an acceptable price to pay for economic growth and development. Nowadays, however, many societies are seeking a better balance between healthy aquatic ecosystems and viable economies. Unfortunately, historically, water allocation systems have privileged human uses over the environment. Thus, jurisdictions seeking to ensure that adequate water is available for the environment must typically deal with the fact that economies and communities have become dependent on water. Additionally, they must often layer institutions for environmental water allocation (EWA on top of already complex institutional systems. This paper explores EWA in a jurisdiction – New South Wales (NSW, Australia – where water scarcity has become a priority. Using an in-depth case study of EWA in the Murrumbidgee catchment, NSW, we characterise the NSW approach to EWA with the goal of highlighting the myriad challenges encountered in EWA planning and implementation. Sharing water between people and the environment, we conclude, is much more than just a scientific and technical challenge. EWA in water-scarce regions involves reshaping regional economies and societies. Thus, political and socio-economic considerations must be identified and accounted for from the outset of planning and decision-making processes.

    This study analyzes the production of biogas from aerobic digestion of energy crops. The production of biogas is an important case study because its spread, similar to other sources of bioenergy, creates questions about the environmental effects, the competition in the food market as well as the progressive change of land use. In particular is hereby analyzed the nexus between bioenergy production and water, which plays a key role because water resources are often the limiting factor in energy production from energy crops. The environmental performances of biogas production were analyzed through Water Footprint (WF) and Life cycle assessment (LCA): the integration of LCA and WF represents an attempt of taking advantage of their complementary strengths in environmental assessment, trying to give a comprehensive analysis of bioenergy production sustainability. Eighteen scenarios were considered, trying to figure out the performances of different combinations of locations (north, center, south Italy), crops (maize, sorghum, wheat) and treatments (anaerobic digestion with water dilution or manure co-digestion). WF assessment shows that cultivation phase is the most impacting on water resource use along the entire system life cycle. In particular, water requirements for crop growth shows that sorghum is the more water saver crop (in terms of consumptive water use to produce the amount of crop needed to produce 1 GJ of biogas energy content). Moreover WF investigates the kind of water use and shows that wheat, despite being the most intensive water user, exploits more green water than the other crops.WF was evaluated with respect to water stress indicators for the Italian territory, underlining the higher criticalities associated with water use in southern Italy and identifying consumptive blue water use, in this area, as the main hotspot. Therefore biogas production from energy crops in southern Italy is unsustainable from a water management perspective. At a basin

    In the face of increased pressures on water resources as well as climate change, the need for managing water allocation is important. This study sought to model water allocation under climate change and human pressure. The Loumbila dam located in central Burkina Faso (12°29 N, 01°24 W) plays a great role in the capital's water supply system and is selected as a case study to reconstitute inflows, simulate actual water allocation and predict monthly water allocation under different climate change scenarios using AFR-44-HIRHAM5 bias corrected data. For these purposes, the inflow of the dam was reconstituted through regression method. The water allocation model (WEAP) has been applied to simulate monthly water availability and demand under RCP_8.5 and RCP_4.5 scenarios by 2050. RCMs data bias correction was set up based on delta change method. The assessment of water needs shows an upward trend of water supply meaning that this site will experience great challenges in the near future. The unmet demand for all sites will increase due to the decrease in water availability and increase in water demand. Analysis of the average monthly unmet demands from water supply shows an increase of water need up to 6.5 million of cubic meter in April-May with RCP_8.5 scenarios while scenarios 4.5 simulate a future unmet water supply demand less than 3.5 million of cubic meters in April-May period. Thus both scenarios show increasing unmet water supply demand. The monthly unmet demand from the municipalities needs shows an increase up to 69 000 cubic meters in December under RCP_8.5 scenarios. The analysis shows also an increase of irrigation water need up to 750 000 cubic meters under RCP_8.5 scenarios.

    Full Text Available The aim of this paper is to analyze two Finnish Joint Regional Authorities for Water Supply—namely the Raisio-Naantali Joint Municipal Authority for Water Supply (established in 1957 and the Tuusula Region Joint Municipal Authority for Water Supply (established in 1967—for assessing the development of supra-municipal water governance. The above two cases make it possible to analyze and assess water policies in settings where the owners are groups of municipalities. The analysis is based on two separately conducted case studies. The study data consist of several types of materials: Annual reports, local government documents, etc. The conducted interviews were semi-structured with some themes defined beforehand. The studies describe two authorities in the context of historical development and as a part of local development.

  16. Exploring the Politics of Water Grabbing: The Case of Large Mining Operations in the Peruvian Andes

    Directory of Open Access Journals (Sweden)

    Milagros Sosa

    2012-06-01

    Full Text Available The operations of the large mining company Yanacocha in Cajamarca (Peru provoke and require a fundamental reshuffling of how rights to water are allocated, resulting in changes in the distribution of the benefits and burdens of accessing water. We use this paper to argue that these changes in water use and tenure can be understood as a form of water grabbing, since they result in a transfer of water control from farmers’ collectives and government agencies to the mining company, with the company also assuming de facto responsibility over executing water allocation and safeguarding certain water-quality levels. We illustrate – by using two cases: La Ramada canal and the San José reservoir – the company’s overt and covert strategies to achieve control over water, showing how these are often backed up by neo-liberal government policies and by permissive local water authorities. Next to active attempts to obtain water rights, these strategies also include skilfully bending and breaking the resistance of (some farmers through negotiation and offering compensation. The de facto handing over of water governance powers to a multinational mining company raises troubling questions about longer-term water management, such as who controls the mining company, to whom are they accountable, and what will happen after mining operations stop.

    Human health is greatly affected by inadequate access to sufficient and safe drinking water, especially in low and middle-income countries. Drinking water governance improvements may be one way to better drinking water quality. Over the past decade, many projects and international organizations have been dedicated to water governance; however, water governance in the drinking water sector is understudied and how to improve water governance remains unclear. We analyze drinking water governance challenges in three countries-Brazil, Ecuador, and Malawi-as perceived by government, service providers, and civil society organizations. A mixed methods approach was used: a clustering model was used for country selection and qualitative semi-structured interviews were used with direct observation in data collection. The clustering model integrated political, economic, social and environmental variables that impact water sector performance, to group countries. Brazil, Ecuador and Malawi were selected with the model so as to enhance the generalizability of the results. This comparative case study is important because similar challenges are identified in the drinking water sectors of each country; while, the countries represent diverse socio-economic and political contexts, and the selection process provides generalizability to our results. We find that access to safe water could be improved if certain water governance challenges were addressed: coordination and data sharing between ministries that deal with drinking water services; monitoring and enforcement of water quality laws; and sufficient technical capacity to improve administrative and technical management of water services at the local level. From an analysis of our field research, we also developed a conceptual framework that identifies policy levers that could be used to influence governance of drinking water quality on national and sub-national levels, and the relationships between these levers.

    Quantify the health impacts on morbidity of reduced car trips and increased public transport and cycling trips. A health impact assessment study of morbidity outcomes related to replacing car trips in Barcelona metropolitan (3,231,458 inhabitants). Through 8 different transport scenarios, the number of cases of disease or injuries related to physical activity, particulate matter air pollution population. A 40% reduction in long-duration car trips substituted by public transport and cycling trips resulted in annual reductions of 127 cases of diabetes, 44 of cardiovascular diseases, 30 of dementia, 16 minor injuries, 0.14 major injuries, 11 of breast cancer and 3 of colon-cancer, amounting to a total reduction of 302 Disability Adjusted Life Years per year in travelers. The reduction in PM2.5 exposure in the general population resulted in annual reductions of 7 cases of low birth weight, 6 of preterm birth, 1 of cardiovascular disease and 1 of lower respiratory tract infection. Transport policies to reduce car trips could produce important health benefits in terms of reduced morbidity, particularly for those who take up active transportation. © 2013.

    Climate change may increase the incidence of waterborne diseases due to extreme rainfall events, and consequent microbiological contamination of the water source and supply. As a result of the complexity of the pathways from the surface to the consumer, it is difficult to detect an association between rainfall and human disease. The water supply of a Hungarian city, Miskolc (174,000 inhabitant), is mainly based on karstic water, a vulnerable underground water body. A large amount of precipitation fell on the catchment area of the karstic water source, causing an unusually strong karstic water flow and flooding, and subsequent microbiological contamination. The presence of several potential sources of contamination in the protective zone of the karstic water source should be emphasized. The water supplier was unprepared to treat the risk of waterborne outbreak caused by an extreme weather event. Public health intervention and hygienic measures were taken in line with epidemiological actions, focusing on the protection of consumers by providing safe drinking water. The contamination was identified, and measures were taken for risk reduction and prevention. This case study underlines the increasing importance of preparedness for extreme water events in order to protect the karstic water sources and to avoid waterborne outbreaks.

    Global climate and environmental changes are endangering global water resources; and several approaches have been tested to manage and reduce the pressure on these decreasing resources. This study uses the case study of Xi'an City in China to test reasonable and effective methods to address water resource shortages. The study generated a framework combining ecosystem services and water resource management. Seven ecosystem indicators were classified as supply services, regulating services, or cultural services. Index values for each indicator were calculated, and based on questionnaire results, each index's weight was calculated. Using the Likert method, we calculated ecosystem service supplies in every region of the city. We found that the ecosystem's service capability is closely related to water resources, providing a method for managing water resources. Using Xi'an City as an example, we apply the ecosystem services concept to water resources management, providing a method for decision makers.

    Full Text Available This article briefly elaborates on the uses of water in services and activities related to sun and beach tourism in dry regions such as Guanacaste, in the North Pacific of Costa Rica. The concept of water footprint is used to understand the relationship between tourism and water consumption. This document discusses the implications of this approach of consumption, especially in dry environments that depend on underground extraction of water. The information comes from secondary sources review and its contextualization to the case of Guanacaste. The purpose of this paper is to provide some orientation to the discussions taking place among several involved participants in the area about the usage of water in dry environments and how this orientation should manifest itself in public policies that guide water management.

    Water resources are essential for socio-economic development, enabling, for example, hydropower and irrigation. Water resources management and development are expected to become more complex and challenging and to involve new uncertainties as water development increases and accelerates in different water use sectors and is coupled with increasing population, urbanisation, and climate change. Hence, water resources need to be managed in more integrated and sustainable way, both in Lao PDR and in the whole Mekong Basin area. Integrated Water Resources Management (IWRM) has become a universal paradigm of enhancing and promoting sustainable and equal water resources management and use. However, integrating water functions is a very complex task as it involves many actors with different interests. This research analyses the application of the IWRM approach and the related principles of integration, decentralisation, and participation in the development and management of water resources in Laotian water regime at the water use sectors of hydropower and irrigation. A case study approach was used for the research and for the four appended articles in order to examine hydropower and irrigation sectors, institutional structures, and processes of institutional change - Integrated Water Resources Management (IWRM) at constitutional, organisational, and operational levels. The constitutional level refers to water policy and law, organisational to water resource management, and operational to water use. The Management and Transition Framework (MTF) and one of its components, Institutional Analysis and Development (IAD) framework, have been used for the research to explore processes, institutions, and actors related to water governance reforms including the adoption of the IWRM paradigm, and to increase understanding of the strengths and weaknesses related to different institutional contexts and levels in Laotian water management. Through Action Situations, IAD and MTF have

    Full Text Available Water is an essential element for life, and development would not be possible without its availability. This study identified the main water consumers and their likely impact on water lake level for the case of Issyk-Kul Lake Basin, Kyrgyzstan. Data on precipitation, lake level, irrigation, household and industrial water consumption from 1980 to 2014 were provided by the Department of Water Resources and Irrigation, Ministry of Agriculture and Land Reclamation of the Kyrgyz Republic. The input data was analyzed with OriginPro 8.5 for Statistical Analysis. The results indicated a decreasing irrigation water consumption from 2029.42 to 461.76 million·m3 in 1980 and 2014, respectively. Likewise, households consumed 27.02 million·m3 in 1980 falling to 16.55 million·m3 in 2014, similar to the manufacture’s water consumption. However, it was noted that agriculture is a high water consumer, whose water demand for irrigation rises from April to August, the period during which the precipitation also increases. Nevertheless, manufactures and household water consumption do not have timed limits of use like in agriculture, which in turn affects the lake water level. Therefore, as the rainfall increases by April to August, we suggest to harvest and only use the rainfall water during its abundance period. This would help in restoring the lake’s water level during the time of rainwater uses, and leads to water consumption balance, flood management and lake biodiversity conservation as well.

    Large-scale U.S. dependence on thermoelectric (steam electric) generation requiring water for cooling underscores the need to understand controls on this water use. The study objective was to quantify water consumption and withdrawal for thermoelectric generation, identifying controls, using Texas as a case study. Water consumption for thermoelectricity in Texas in 2010 totaled ∼0.43 million acre feet (maf; 0.53 km3), accounting for ∼4% of total state water consumption. High water withdrawals (26.2 maf, 32.3 km3) mostly reflect circulation between ponds and power plants, with only two-thirds of this water required for cooling. Controls on water consumption include (1) generator technology/thermal efficiency and (2) cooling system, resulting in statewide consumption intensity for natural gas combined cycle generators with mostly cooling towers (0.19 gal/kWh) being 63% lower than that of traditional coal, nuclear, or natural gas steam turbine generators with mostly cooling ponds (0.52 gal/kWh). The primary control on water withdrawals is cooling system, with ∼2 orders of magnitude lower withdrawals for cooling towers relative to once-through ponds statewide. Increases in natural gas combined cycle plants with cooling towers in response to high production of low-cost natural gas has greatly reduced water demand for thermoelectric cooling since 2000.

    2014-05-01

    The latest reports of the intergovernmental panel on climate change explained that the Mediterranean regions are especially vulnerable to the impacts of climate change. These latest are expected to have strong impacts on the management of water resources and on regional economies. The aim of this paper is to discuss impacts of climate changes on the Thau case study in relation to the evolution of water balance, water uses and adaptation to climate change. The Thau coastal lagoon is located in the Mediterranean coast in south of France in the Languedoc-Roussillon Region. Economic activities are diverse from shellfish farming, fertilizers industries to agriculture and tourism. However, tourism and shellfish farming are of major importance for local economy. If tourism is mainly turned to the Sea coast, shellfishes grow within the lagoon and rely on water quality. Previous studies have demonstrated the link between the coastal lagoon water quality and inputs of freshwater from the catchment. Thus, changes in rainfalls, runoff and water balance would not only affect water uses but also water quality. Climate changes projections are presented following the implementation of 4 downscaled climatic models. Impacts on water balance are modelled with SWAT (Soil Water Assessment Tool) for 2041-2070 compared to the 1971-2000 reference period. The decrease of precipitations and water balance will impact discharges and thus decrease the freshwater inputs to the coastal lagoon. A study of water uses conducted in interactions with stakeholders within the Thau area has permitted to assess both current and evolution of water uses. It has revealed local water resources are depleting while water demand is increasing and is planned to continue to increase in the really near future. To prevent water scarcity events, mainly due to the climate change context, the Regional authorities have connected the catchment to the Rhône river to import water. The conclusion of this study is while

    2013-02-01

    Full Text Available The relationships between optical properties and water constituents in highly turbid productivewater were studied on the basis of the multiple bio-optical measurements and samplings of water constituents made during five cruises from 2006 to 2008 in Taihu lake. Taihu lake is a high dynamic ratio [(square root of area/depth] inland shallow lake. The spatial and temporal variation of water constituents and optical properties is significant. The inorganic suspended matter (ISMhas become the primary constituent in Taihu lake: its average percentage can reach 65.21%. The concentration of ISM is highly correlated to the optical properties in Taihu lake due to the sediment resuspension. Consequently, the ISM can be taken into account as an important optically-active constituent in Taihu lake. Resuspended sediments also lead to a poor correlation between scattering optical property and chlorophyll-a concentration (CChl-a. However, empirical relationship between the CChl-a and phytoplankton absorption coefficient at 675 nm is still valid when the package effect is removed. The parameters of linear equation in the present study have slight temporal variation, especially for the relationship between inherent optical properties (IOPs and concentration of total suspended matter (TSM. The relationship between apparent optical property (AOP (diffuse attenuation coefficient of particle, Kdbio and ISM has been examined as well. The Kdbio is strongly affected by ISM, and correlates to it with linear function. Thedifference between specific diffuse attenuation coefficients of organic [K*dOSM(λ] and inorganic [K*dISM(λ] particles is significant. K*dOSM(λ includes the absorption property of chlorophyll-a (chl-a at 675 nm, which is much higher than that of K*dISM(λ. This indicates that the attenuation ability of OSM is stronger than that of ISM although the Kdbio induced by large concentration of ISM is bigger than the Kdbio induced by small concentration of OSM

    Full Text Available In some Chilean cities, levels of arsenic (As in drinking water reached 800 µg/L between 1950 and 1970, while current levels are 40 µg/L. To evaluate the causal role of this exposure in lung and bladder cancers, we conducted a case-control study in Regions I, II, and III of the country. From 1994 to 1996, cases diagnosed as lung cancer and two hospital controls were entered in the study; one control was a patient with a cancer, while the other was a patient without cancer, both conditions unrelated to As. Controls were matched with cases by age and sex. A standard survey containing questions about residence, employment, health history, was administered to study subjects. Data on As concentrations in water were obtained from records of the municipal water companies. A total of 151 lung cancer cases and 419 controls (167 with cancer and 242 without cancer were enrolled. Median level of lifetime As exposure was significantly higher among cases, with a clear dose-response relationship between mean As exposure levels, with an OR (95% CI of: 1, 1.7 (0.5-5.1, 3.9 (1.2-13.4, 5.5 (2.2-13.5, and 9.0 (3.6-22 for strata one to five respectively. This study provides new evidence that As in drinking water can cause internal cancers and gives an estimate of the form of this relationship.

    The aim of this study was to describe the evolution and epidemiologic characteristics of shigellosis patients over a 25 year period in a large city. Shigellosis is a notifiable disease in Spain since 1988. Cases are analyzed in Barcelona residents included in the registry between 1988-2012. A descriptive analysis by sex, age, mode of transmission and Shigella species is presented. Trend analysis and time series were performed. Of the 559 cases analyzed, 60.15% were males. A sustained increase was observed in the trend since 2008 in males (p<0,05), especially at the expense of males who had no history of food poisoning or travel to endemic areas. The increasing tendency was greater in males from 21 to 60 years, both for S. flexneri (since 2009), and for S. sonnei (since 2004). In 2012 it was noted that in the men with S. flexneri, the 63% were men who have sex with men. An increased trend was detected in men who had no history of food poisoning or travel to endemic areas. This increase points to a change in the pattern of shigellosis, becoming predominantly male and its main mechanism probably by sexual transmission.

    The urban air quality in Barcelona in the Western Mediterranean Basin is characterized by overall high particulate matter (PM) concentrations, due to intensive local anthropogenic emissions and specific meteorological conditions. Moreover, on several days, especially in summer, natural PM sources, such as long-range transported Saharan dust from Northern Africa or wildfires on the Iberian Peninsula and around the Mediterranean Basin, may influence the levels and composition of the organic aerosol. In the second half of July 2009, daily collected PM(10) filter samples in an urban background site in Barcelona were analyzed on organic tracer compounds representing several emission sources. During this period, an important PM peak event was observed. Individual organic compound concentrations increased two to five times during this event. Although highest increase was observed for the organic tracer of biomass burning, the contribution to the organic aerosol was estimated to be around 6 %. Organic tracers that could be related to Saharan dust showed no correlation with the PM and OC levels, while this was the case for those related to fossil fuel combustion from traffic emissions. Moreover, a change in the meteorological conditions gave way to an overall increase of the urban background contamination. Long-range atmospheric transport of organic compounds from primary emissions sources (i.e., wildfires and Saharan dust) has a relatively moderate impact on the organic aerosol in an urban area where the local emissions are dominating.

    2009-01-01

    Agro-based pulp and paper mills in India are one of the most polluting industries; in addition, they are high consumers of raw water. Growing scarcity of high quality freshwater as well as stringent regulatory standards is compelling these units to explore appropriate water management options. Based on data obtained through a questionnaire survey and plant visits, this work provides an overview of the water use and effluent treatment status in Indian agro-residue and recycled pulp and paper mills. The challenges faced by this sector are reviewed and practices adopted by progressive units to minimize freshwater use are illustrated through case studies.

  20. Modeling integrated urban water systems in developing countries: case study of Port Vila, Vanuatu.

    Poustie, Michael S; Deletic, Ana

    2014-12-01

    Developing countries struggle to provide adequate urban water services, failing to match infrastructure with urban expansion. Despite requiring an improved understanding of alternative infrastructure performance when considering future investments, integrated modeling of urban water systems is infrequent in developing contexts. This paper presents an integrated modeling methodology that can assist strategic planning processes, using Port Vila, Vanuatu, as a case study. 49 future model scenarios designed for the year 2050, developed through extensive stakeholder participation, were modeled with UVQ (Urban Volume and Quality). The results were contrasted with a 2015 model based on current infrastructure, climate, and water demand patterns. Analysis demonstrated that alternative water servicing approaches can reduce Port Vila's water demand by 35 %, stormwater generation by 38 %, and nutrient release by 80 % in comparison to providing no infrastructural development. This paper demonstrates that traditional centralized infrastructure will not solve the wastewater and stormwater challenges facing rapidly growing urban cities in developing countries.

    To describe knowledge of electronic cigarettes (e-cigarettes) and their perceived harmfulness in the population of Barcelona in 2013-2014. We used participants from a longitudinal study of a representative sample of the adult population in the city of Barcelona (n=736). The field work was conducted between May 2013 and February 2014. Awareness of e-cigarette was 79.2%. The average level of knowledge was 4.4 points out of 10; there were statistically significant differences according to age, educational level, tobacco consumption, and nicotine dependence. Most participants had learned about e-cigarettes through traditional media (57.8%). Nearly half (47.2%) of the participants believed that e-cigarettes are less harmful than conventional cigarettes. Advertising of e-cigarettes in the media should be regulated because there is still scarce scientific evidence about the usefulness and harmful effects of these devices. Copyright © 2014 SESPAS.

    Full Text Available The article reviews peculiarities of the architectural and spatial organization of the Barcelona Pavilion designed by Mies van der Rohe and the reasons for its rehabilitation after a long period of oblivion. The analysis of the display shows that the only exhibit item of the Barcelona Pavilion is its architecture and furniture compositions designed by the author. The characteristics of partitions, screens, glass surfaces and the position of transparent walls of this construction are of special interest. The style of the building designed by Mies van der Rohe may be referred to formalism, rather than the traditional European functionalism. The article shows a special role of this construction in the architect’s creative work

    2007-01-01

    Full Text Available Barcelona is today a city of reference within the world’s tourist map. Created as a process of both an economic evolution towards the third sector as well as a powerful brand image, from the Olympics up to nowadays. Within this scene, Culture and Arts have been pushed at the center of the strategy, building a “cultural spectacle” aimed to differentiate the city’s offer in the market. Furthermore, some specific icons oriented to give it a Catalan, Cosmopolitan and Modern identity are promoted, adding also new symbolic values such as diversity, tolerance or Mediterranean character. Meaning that some range of cultural heritages should be reinforced while others are put aside or even hidden. Barcelona appears then as the result of a perfectly drawn political strategic planning, under the appearance of social consensus and citizens’ involvement

    To describe the prevalence and correlates of safety belt and mobile phone usage in vehicles in the city of Barcelona (Spain). We performed a study using direct observation with a cross-sectional design. We selected 2,442 private cars, commercial vehicles, and taxis from all districts of Barcelona. The prevalence of people not wearing safety belt was 10.5% among drivers, 4.6% among front seat passengers, and 32.2% among some of the rear passengers. It was higher among the passengers than among the drivers, regardless of the type of the vehicle. The prevalence of mobile phone usage while driving during a moment of the trip was 3.8%. Our study shows noticeably high prevalence of people not wearing safety belt in the rear seats. Moreover, four out of one hundred drivers still use the mobile phone while driving during a moment of the trip. Copyright © 2013 SESPAS. Published by Elsevier Espana. All rights reserved.

  5. Multi-level Governance as an Alternative: The Municipality of Barcelona and the Ciutat Refugi Plan

    Ezgi Irgil

    2016-12-01

    Full Text Available This paper analyses the response of the Municipality of Barcelona to the Syrian refugee crisis in Europe as an alternative solution that challenges the national government’s restrictive approach. This response introduces the Ciutat Refugi Plan with a city-to-city network at the municipal level that involves other European cities in creating safe routes for refugees at the local government level. In line with multi-level governance theory, I argue that central governments’ inaction has pressured local governments to take action during the Syrian refugee influx. Relying on the influence of local government networks, the Municipality of Barcelona uses discourse as a tool of action in opening discursive spaces for humanitarian political responses to the refugee crisis. Using critical discourse analysis, I test this argument by examining in-depth interviews, speeches of people in power that have appeared in news articles, and statements on official websites.

  7. Building America Case Study: Assessment of a Hybrid Retrofit Gas Water Heater

    Energy Technology Data Exchange (ETDEWEB)

    2017-06-19

    This project completed a modeling evaluation of a hybrid gas water heater that combines a reduced capacity tankless unit with a downsized storage tank. This product would meet a significant market need by providing a higher efficiency gas water heater solution for retrofit applications while maintaining compatibility with the half-inch gas lines and standard B vents found in most homes. The TRNSYS simulation tool was used to model a base case 0.60 EF atmospheric gas storage water, a 0.82 EF non-condensing gas tankless water heater, an existing (high capacity) hybrid unit on the market, and an alternative hybrid unit with lower storage volume and reduced gas input requirements. Simulations were completed under a 'peak day' sizing scenario with 183 gpd hot water loads in a Minnesota winter climate case. Full-year simulations were then completed in three climates (ranging from Phoenix to Minneapolis) for three hot water load scenarios (36, 57, and 96 gpd). Model projections indicate that the alternative hybrid offers an average 4.5% efficiency improvement relative to the 0.60 EF gas storage unit across all scenarios modeled. The alternative hybrid water heater evaluated does show promise, but the current low cost of natural gas across much of the country and the relatively small incremental efficiency improvement poses challenges in initially building a market demand for the product.

  8. Smallholder Irrigators, Water Rights and Investments in Agriculture: Three Cases from Rural Mozambique

    Directory of Open Access Journals (Sweden)

    Gert Jan Veldwisch

    2013-02-01

    Full Text Available In the context of the prevalent neo-liberal discourse on rural development through improved markets, involvement of companies and a strong reliance on foreign investors this article examines the vulnerable position of smallholder irrigators and their water rights. Through the parallel analysis of three contrasting cases of smallholder irrigation in Mozambique and a comparison with formal Mozambican law, it is shown that a big gap exists between formal water rights and water rights in practice. For each case, it is shown how land and water rights are connected and how a successful defence of land rights provides a good basis for a defence of smallholder water rights. Furthermore, as productivity and efficiency arguments are prominent and influential, those smallholders who are able to turn their use into the production of economic value manage best to materialise their claims on both land and water. The paper concludes with recommendations to strengthen the position of smallholders in response to increasing threats of land and water grabbing.

  9. Developing a national framework for safe drinking water--case study from Iceland.

    Gunnarsdottir, Maria J; Gardarsson, Sigurdur M; Bartram, Jamie

    2015-03-01

    Safe drinking water is one of the fundaments of society and experience has shown that a holistic national framework is needed for its effective provision. A national framework should include legal requirements on water protection, surveillance on drinking water quality and performance of the water supply system, and systematic preventive management. Iceland has implemented these requirements into legislation. This case study analyzes the success and challenges encountered in implementing the legislation and provide recommendations on the main shortcomings identified through the Icelandic experience. The results of the analysis show that the national framework for safe drinking water is mostly in place in Iceland. The shortcomings include the need for both improved guidance and control by the central government; and for improved surveillance of the water supply system and implementation of the water safety plan by the Local Competent Authorities. Communication to the public and between stakeholders is also insufficient. There is also a deficiency in the national framework regarding small water supply systems that needs to be addressed. Other elements are largely in place or on track. Most of the lessons learned are transferable to other European countries where the legal system around water safety is built on a common foundation from EU directives. The lessons can also provide valuable insights into how to develop a national framework elsewhere. Copyright © 2014 Elsevier GmbH. All rights reserved.

  10. Separation of the tumor and brain surface by "water jet" in cases of meningiomas.

    1987-01-01

    In the surgery of meningiomas one of the most delicate problems is the separation of the tumor from the brain surface. The authors generally recommend microsurgery to preserve the brain surface anatomically and functionally. For this purpose we have developed a new surgical technique according to our concepts of tissue care. After excavating the tumor from inside the tumor brain surface was separated by repeated "water jets" into the tumor arachnoideal space. The "water jet" was produced by an ordinary bulb syringe. The front pressure of the jets was 300-1000 mm of water and the side pressure 100-300 mm of water. In the tumor-arachnoideal space the spreading water (phys. NaCl) separates the brain from the tumor with utmost care. We operated on 55 meningiomas of different types with the "water jet" technique. The immediate results were anatomically excellent. Intraoperative and postoperative acute and late edemas appeared only in a few cases. The functions of the nearby brain were generally preserved. The surgery was uneventful when the tumor surface was smooth and the tumor was spherical. When the tumor surface was uneven, one part of the tumor extended under the dura as a thin layer or the tumor was multilobulated with expanded vessels between the lobules, more microseparation was necessary. We compared the results of the "water jet" technique with the results of the "pre-water jet" series. The surgery with the "water jet" technique was much shorter and its results were better than those of microsurgery alone.

    Key similarities exist between marine and Great Lakes coastal environments. Water and nutrient fluxes across lakebeds in the Great Lakes are influenced by seiche and wind set-up and set-down, analogous to tidal influence in marine settings. Groundwater/surface-water interactions also commonly involve a saline-fresh water interface, although in the Great-Lakes cases, it is groundwater that is commonly saline and surface water that is fresh. Evapotranspiration also affects nearshore hydrology in both settings. Interactions between groundwater and surface water have recently been identified as an important component of ecological processes in the Great Lakes. Water withdrawals and the reversal of the groundwater/surface water seepage gradient are also common to many coastal areas around the Great Lakes. As compared to surface water, regional groundwater that discharges to western Lake Erie from Michigan is highly mineralized. Studies conducted by the U.S. Geological Survey at Erie State Game Area in southeastern Michigan, describe groundwater flow dynamics and chemistry, shallow lake-water chemistry, and fish and invertebrate communities. Results presented here provide an overview of recent progress of ongoing interdisciplinary studies of Great Lakes nearshore systems and describe a conceptual model that identifies relations among geologic, hydrologic, chemical, and biological processes in the coastal habitats of Lake Erie. This conceptual model is based on analysis of hydraulic head in piezometers at the study site and chemical analysis of deep and shallow coastal groundwater.

The average amount of catchment water stays around 2.0 m3 Mg 1 of industrial sugarcane stalk. However, in some modern mills which use higher technical level of closed water circuit, the standard goal for sugarcane industry, 1.0 m3 Mg 1 can be reached. In some regions where the uptake water for industrial segment is high as in São Paulo State, water use assessment is desired for sustainable ethanol production. Thus, two regions in São Paulo State with two plants each were taken as a case study aiming to assess ethanol water demand during the industrial phase. Araraquara was the first study region where the water demand was classified as in critical condition in 2010 according to the Water and Electrical Energy Department of São Paulo State (DAEE). The industrial activities were responsible for 50% of the water catchment. Araçatuba was the second study region where water demand was classified as being of concern (DAEE) due to high percentage of catchment water for industrial activities, around 90%. Data regarding the amount of millable cane processed, days of the plant operation, ratio of cane used for ethanol production in 2010/2011 season were used for direct water demand estimation considering different water catchment scenarios of 2.0, 1.0 and 0.7 (technological development prediction scenario) m3 Mg-1 of millable cane.

    2017-08-01

    In the 1980s, a case-control epidemiologic study was conducted in Iowa (USA) to analyze the association between exposure to disinfection by-products (DBPs) and bladder cancer risk. Trihalomethanes (THMs), the most commonly measured and dominant class of DBPs in drinking water, served as a primary metric and surrogate for the full DBP mixture. Average THM exposure was calculated, based on rough estimates of past levels in Iowa. To reduce misclassification, a follow-up study was undertaken to improve estimates of past THM levels and to re-evaluate their association with cancer risk. In addition, the risk associated with haloacetic acids, another class of DBPs, was examined. In the original analysis, surface water treatment plants were assigned one of two possible THM levels depending on the point of chlorination. The re-assessment considered each utility treating surface or groundwater on a case-by-case basis. Multiple treatment/disinfection scenarios and water quality parameters were considered with actual DBP measurements to develop estimates of past levels. The highest annual average THM level in the re-analysis was 156μg/L compared to 74μg/L for the original analysis. This allowed the analysis of subjects exposed at higher levels (>96μg/L). The re-analysis established a new approach, based on case studies and an understanding of the water quality and operational parameters that impact DBP formation, for determining historical exposure.

    In the past three decades, the fast development of economy and urbanization has caused increasingly severe pollutions of urban water bodies in China. Consequently, eutrophication and deterioration of aquatic ecosystem, which is especially significant for aquatic vegetation, inevitably became a pervasive problem across the Yangtze River Basin. To rehabilitate the degraded urban water bodies, vegetation replanting is an important issue to improve water quality and to rehabilitate ecosystem. As a case study, a representative polluted urban river, Nanfeihe River, in Hefei City, Anhui Province, was chosen to be a rehabilitation target. In October 2009 and May 2010, 13 species of indigenous and prevalent macrophytes, including seven species emergent, one species floating leaved, and five species submersed macrophytes, were planted along the bank slopes and in the river. Through 1.5 years' replanting practice, the water quality and biodiversity of the river had been improved. The concentrations of total nitrogen (TN), total phosphorus (TP), and ammonia nitrogen (NH4 (+)-N) declined by 46.0, 39.5, and 60.4 %, respectively. The species of macrophytes increased from 14 to 60, and the biodiversity of phytoplankton rose significantly in the river (p<0.05). The biomasses of zooplankton and benthos were also improved after the vegetation replanting. The study confirmed that vegetation replanting could alleviate the increasing water pollution and rehabilitate the degraded aquatic ecosystem. The case study would be an example for polluted urban waters restoration in the middle-downstream area of Yangtze River Base.

    Water quality monitoring using remote sensing has been studied in Finland for many years. But there are still few discussions on water quality monitoring using remote sensing technology in support of water policy and legislation in Finland under the WFD. In this study, we present water quality monitoring using remote sensing in the Gulf of Finland, and focus on the spatial distribution of water quality information from satellite-based observations in support of water policy by a case study of nitrate concentrations in surface waters. In addition, we briefly describe instruments using a system of river basin districts (RBD), highlighting the importance of integrated water resources and river-basin management in the WFD, and discuss the role of water quality monitoring using remote sensing in the implementation of water policy in Finland under the WFD.

    Full Text Available Burkina Faso is actively pursuing the implementation of Integrated Water Resources Management (IWRM in its development plans. Several policy and institutional mechanisms have been put in place, including the adoption of a national IWRM action plan (PAGIRE and the establishment so far of 30 local water management committees (Comités Locaux de l’Eau, or CLE. The stated purpose of the CLE is to take responsibility for managing water at sub-basin level. The two case studies discussed in this paper illustrate gaps between the policy objective of promoting IWRM on the one hand, and the realities associated with its practical on-the-ground implementation on the other. A significant adjustment that occurred in practice is the fact that the two CLE studied have been set up as entities focused on reservoir management, whereas it is envisioned that a CLE would constitute a platform for sub-basin management. This reflects a concern to minimise conflict and optimally manage the country’s primary water resource and illustrates the type of pragmatic actions that have to be taken to make IWRM a reality. It is also observed that the local water management committees have not been able to satisfactorily address questions regarding access to, and allocation of, water, which are crucial for the satisfactory functioning of the reservoirs. Water resources in the reservoirs appear to be controlled by the dominant user. In order to correct this trend, measures to build mutual trust and confidence among water users 'condemned' to work together to manage their common resource are suggested, foremost of which is the need to collect and share reliable data. Awareness of power relationships among water user groups and building on functioning, already existing formal or informal arrangements for water sharing are key determinants for successful implementation of the water reform process underway.

    Microgrids can provide reliable and cost-effective energy services in a variety of conditions and locations. To date, there has been minimal effort invested in developing energy-water microgrids that demonstrate the feasibility and leverage the synergies associated with designing and operating renewable energy and water systems in a coordinated framework. Water and wastewater treatment equipment can be operated in ways to provide ancillary services to the electrical grid and renewable energy can be utilized to power water-related infrastructure, but the potential for co-managed systems has not yet been quantified or fully characterized. Co-management and optimization of energy and water resources could lead to improved reliability and economic operating conditions. Energy-water microgrids could be a promising solution to improve energy and water resource management for islands, rural communities, distributed generation, Defense operations, and many parts of the world lacking critical infrastructure.The National Renewable Energy Laboratory (NREL) and the University of Arizona have been jointly researching energy-water microgrid opportunities through an effort at the university's BioSphere 2 (B2) Earth systems science research facility. B2 is an ideal case study for an energy-water microgrid test site, given its size, its unique mission and operations, the existence and criticality of water and energy infrastructure, and its ability to operate connected-to or disconnected-from the local electrical grid. Moreover, the B2 is a premier facility for undertaking agricultural research, providing an excellent opportunity to evaluate connections and tradeoffs in the food-energy-water nexus. The research effort at B2 identified the technical potential and associated benefits of an energy-water microgrid through the evaluation of energy ancillary services and peak load reductions and quantified the potential for B2 water-related loads to be utilized and modified to provide

    Contact lenses have been widely used as an alternative to spectacles both in developed and developing countries. However, under certain circumstances, adverse responses can occur during contact lens wear and several microorganisms--including bacteria, fungi, and free living amoebae--can cause several eye infections in wearers. Extended wear of contact lenses is the major risk factor of eye infections such as microbial keratitis, besides contaminated contact lens storage case, contaminated lens care solutions, and inaccurate contact lens handling. In this study, we collected contact lens storage case and domestic tap water samples from 50 asymptomatic contact lens wearers. We determined that total aerobic mesophilic bacteria were isolated in 45 (90 %), Gram negative rod bacteria were isolated in 20 (40 %), Pseudomonas spp. were isolated in 2 (4 %) and fungi were isolated in 18 (36 %) out of 50 contact lens storage cases. Free living amoebae were not detected in investigated contact lens storage cases. At the same time, out of 50, total aerobic mesophilic bacteria were isolated in 34 (68 %), fungi were isolated in 15 (30 %) and free living amoebae were isolated in 15 (30 %) domestic tap water samples. No Gram-negative rod bacteria and Pseudomonas spp. were detected in investigated water samples. Two contact lens case samples and two tap water samples were excluded from the analysis for Pseudomonas spp. for technical reasons. According to our findings, inadequate contact lens maintenance during lens wear may result in the contamination of contact lens storage cases. This situation can lead to severe eye infections in contact lens wearers over time.

    More than 90% of urban water supply and sanitation services in developing countries are provided by public organizations. However, public provision of services has been inherently inefficient. As a result a number of initiatives have emerged in recent years with a common goal to improve service delivery. In Namibia, the water sector reform resulted in the creation of a public utility called the Namibia Water Corporation (NAMWATER) which is responsible for bulk water supply countrywide. Since its inception in 1998, NAMWATER has been experiencing poor financial performance. This paper presents the findings of a case study that compared the management approaches of NAMWATER to the New Public Management (NPM) paradigm. The focus of the NPM approach is for the public water sector to mirror private sector methods of management so that public utilities can accrue the benefits of effectiveness, efficiency and flexibility often associated with private sector. The study tools used were a combination of literature review, interviews and questionnaires. It was found out that NAMWATER has a high degree of autonomy in its operations, albeit government approved tariffs and sourcing of external financing. The utility reports to government annually to account for results. The utility embraces a notion of good corporate culture and adheres to sound management practices. NAMWATER demonstrated a strong market-orientation indicated by the outsourcing of non-core functions but benchmarking was poorly done. NAMWATER’s customer-orientation is poor as evidenced by the lack of customer care facilities. NAMWATER’s senior management delegated operational authority to lower management to facilitate flexibility and eliminate bottlenecks. The lower management is in turn held accountable for performance by the senior management. There are no robust methods of ensuring sufficient accountability indicated by absence of performance contracts or service level agreements. It was concluded that

    Full Text Available In June 2008, the Shenzhen landfill slope failed. This case is used as an example to study the deformation characteristics and failure mode of a slope induced by high water levels. An integrated monitoring system, including water level gauges, electronic total stations, and inclinometers, was used to monitor the slope failure process. The field measurements suggest that the landfill landslide was caused by a deep slip along the weak interface of the composite liner system at the base of the landfill. The high water level is considered to be the main factor that caused this failure. To calculate the relative interface shear displacements in the geosynthetic multilayer liner system, a series of numerical direct shear tests were carried out. Based on the numerical results, the composite lining system simplified and the centrifuge modeling technique was used to quantitatively evaluate the effect of water levels on landfill instability.

    This project completed a modeling evaluation of a hybrid gas water heater that combines a reduced capacity tankless unit with a downsized storage tank. This product would meet a significant market need by providing a higher efficiency gas water heater solution for retrofit applications while maintaining compatibility with the half-inch gas lines and standard B vents found in most homes. The TRNSYS simulation tool was used to model a base case 0.60 EF atmospheric gas storage water, a 0.82 EF non-condensing gas tankless water heater, an existing (high capacity) hybrid unit on the market, and an alternative hybrid unit with lower storage volume and reduced gas input requirements.

    The paper discusses the direct causes of water contamination (the use of fertilisers and pesticides and the presence of cattle and the indirect causes (unclear administrative boundaries, lack of participation and transparency, procedures not followed and limited resources. The negotiation process and its outcomes are described. From this study we conclude that stakeholder communication and transparency are key elements in anticipating and preventing the arising of such situations. Often, these are in short supply when large land deals occur. In this case, ex-post solutions were arrived at. Finally, the paper looks at the broader dimensions of land deals that pollute the water feeding a water supply scheme. Such situations are a clear violation of the human right to safe drinking water – an issue that has not yet been sufficiently documented in the literature and which merits further attention.

    The aims of this multicenter study was to establish the level of primary and acquired drug resistance of M. Tuberculosis strains isolated in Barcelona and to identify possible risk groups using clinical data. All tuberculosis patients with isolation and identification of M. tuberculosis strains from October 1995 to September 1997 were included. Susceptibility tests isoniazid, rifampin, ethambutol, streptomycin and pyrazinamide were performed using the Bactec 460 system and the proportions method on solid medium. Logistic progression was used for statistical analysis. The total number of patients included was 1,749 (1,535 non-treated and 214 previously treated). Primary drug resistance was 5.7% (isoniazid 3.8%; rifampin 1.0%, streptomycin 2.1%, ethambutol 0.3% and pyrazinamide 1.0%). Acquired drug resistance was 20.5% (isoniazid 17.3%, rifampin 9.8%, ethambutol 1.9%, streptomycin 4.7% and pyrazinamide 6.5%). Primary drug resistance was associated with people over 60 years old and women. The low level of drug resistance enables antituberculosis treatment of non-treated patients to start with the standardised three-drug regimes except in the case of foreign people from countries with a high level of drug resistance. Susceptibility tests are recommended on all M. tuberculosis strains isolated, together with controlled studies of drug resistance surveillance.

  13. The Imposition of Participation? The Case of Participatory Water Management in Coastal Bangladesh

    2014-06-01

    Full Text Available Community-based Natural Resources Management (CBNRM has been promoted as part of the development discourse on sustainable natural resources management since the mid-1980s. It has influenced recent water policy in Bangladesh through the Guidelines for Participatory Water Management (GPWM where community-based organisations are to participate in the management of water resources. This paper reviews the extent of success of such participatory water management. It does so by first discussing the changing discourses of participation in Bangladesh’s water policy from social mobilisation to decentralised CBNRM. Second, Bangladesh is used as a case study to draw attention to how the creation of separate water management organisations has been unable to promote inclusive participation. It argues that the current form of decentralisation through a CBNRM framework has not resulted in its stated aims of equitable, efficient, and sustainable management of natural resources; rather it has duplicated existing local government institutions. Finally, it questions the current investments into community-based organisations and recommends that the role of local government in water management be formally recognised.

    Access to safe drinking water is an important issue of health and development at national, regional, and local levels. The concept of safe drinking water assumes greater significance in countries like India where the majority of the population lives in villages with bare infrastructures and poor sanitation facilities. This review presents an overview of drinking water quality in rural habitations of northern Rajasthan, India. Although fluoride is an endemic problem to the groundwater of this region, recently, other anthropogenic chemicals has also been reported in the local groundwater. Recent case studies indicate that about 95% of sites of this region contain a higher fluoride level in groundwater than the maximum permissible limit as decided by the Bureau of Indian Standards. Nitrate (as NO3-) contamination has appeared as another anthropogenic threat to some intensively cultivable rural habitations of this region. Biological contamination has appeared as another issue of unsafe drinking water resources in rural areas of the state. Recent studies have claimed a wide variety of pathogenic bacteria including members of the family Enterobacteriaceae in local drinking water resources. Overall, the quality of drinking water in this area is not up to the safe level, and much work is still required to establish a safe drinking water supply program in this area.

    Water diversion projects are one of the major tools for counteracting water resource shortage in China. Many diversion projects aimed at diverting water from the Yangtze River or other rivers. This study, using one of the lakes receiving Yangtze River water as a case study, illustrated how nutrient, O2, and N2 fluxes across the sediment-water interface (SWI) changed with increasing nitrate loads during in situ benthic chamber incubation. Increasing nitrate loads in the overlying water caused complex changes in the SWI fluxes. Furthermore, responses of the SWI fluxes to increasing nitrate loads were largely driven by season. Dissolved inorganic carbon (DIC), ammonium (NH4(+)), CO2, and N2 fluxes increased with enhanced nitrate loads, likely induced by stimulated anaerobic mineralization. DIC had a stronger response to nitrate additions in late summer versus in winter. Nitrate influxes were enhanced by increasing nitrate loads in winter and showed a similar but stronger response in summer, with a shift from sediment release to influx. Sediment oxygen consumption decreased with increasing nitrate loads in both late summer and, especially, winter. Nitrate addition may have changed the proportions of aerobic and anaerobic respiration, i.e., nitrate competed with O2 as an electron acceptor. With increasing nitrate loads, anaerobic respiration was strengthened in the dark benthic chamber. Water diversion from the heavily polluted Yangtze River to Lake Dazong may be disadvantageous for controlling eutrophication, especially during the summer. Copyright © 2017 Elsevier B.V.

  16. The Water Abstraction License Regime in Italy: A Case for Reform?

    Directory of Open Access Journals (Sweden)

    2016-03-01

    Full Text Available The current Water Abstraction License (WAL regime in Italy is no longer flexible enough to cope with the challenges posed by human-induced climate and global environmental changes. The cornerstones of the current regime were laid down in the 1930s and have remained essentially unchanged ever since. The sole noteworthy reform of the Italian WAL regime was the decentralization of the regulatory competences from the state to the regional authorities in the late 1990s. In this paper, we review the WAL regimes across the administrative regions comprising the Po River Basin District (PRBD, the largest and economically most important in Italy. PRBD’s WAL regime includes a rigid and scattered WAL normative that hinders the performance of bottom-up conflict resolution mechanisms at a basin scale; a water pricing scheme that does not reflect the cost of water conveyance and use, and does not encourage efficient water allocation; and the lack of a central WAL register, which delays and in some cases impedes an environmental impact assessment for issuing new licenses or renewing existing ones, and does not allow prioritizing applications according to their full economic value. We argue these deficiencies may compromise both the integrity of riverine and water dependent ecosystems and the economic uses of water. This paper offers insights that can inform reform of water allocations in the PRBD and elsewhere in Italy and in Europe.

    Cryptosporidium and Giardia pose a threat to human health in rural environments where water supplies are commonly untreated and susceptible to contamination from agricultural animal waste/manure, animal wastewater, septic tank effluents and septage. Our goals for this paper are to: (1) explore the prevalence of these protozoan parasites, where they are found, in what quantities, and which genotypes are present; (2) examine relationships between disease and land use comparing human health risks between rural and urban environments; and (3) synthesize available information to gain a better understanding of risk and risk management for rural water supplies. Our results indicate that Cryptosporidium and Giardia were more prevalent in rural versus urban environments based on the number of positive samples. Genotyping showed that both the human and animal types of the parasites are found in rural and urban environments. Rural areas had a higher incidence of disease compared to urban areas based on the total number of disease cases. Cryptosporidiosis and giardiasis were both positively correlated (p < 0.001) with urban area, population size, and population density. Finally, a comprehensive strategy that creates knowledge pathways for data sharing among multiple levels of management may improve decision-making for protecting rural water supplies.

    To study the evolution of the incidence of early-onset neonatal sepsis (EOS) by Streptococcus agalactiae in the area of Barcelona and to analyze failure of compliance with the prevention protocol. A retrospective review was carried out on EOS cases in 8 Health-Care Centers in the Barcelona area between 2004 and 2010. Forty-nine newborns from 48 mothers were diagnosed with EOS. The incidence was 0.29‰ living newborns (0.18-0.47‰), with no significant differences in the fluctuations along the 7 years. The mortality rate was 8.16%. In 68.5% cases the maternal colonization studies were negative, and in 21% these studies were not performed. No risk factors were detected in 58.3% of pregnant women, and 22.9% of births were premature. In 58% of cases intra-partum antibiotic prophylaxis was not administered because it was not indicated, and in 42% due to failure to follow the protocol (3 strains were resistant to erythromycin). Resistance to clindamycin was 33.3%. The Streptococcus agalactiae serotypes more frequently isolated were iii, v, and ia. No significant changes were detected in the incidence of Streptococcus agalactiae EOS in the 7 years of the study. The increased sensitivity of screening methods with the use of molecular techniques, the performance of susceptibility testing of strains isolated from pregnant women, and the improvement of communication between Health-Care Centers, can contribute to a better implementation of the protocol, as well as to reduce the incidence of EOS.

    Full Text Available Pressurized water systems are designed to guarantee the flow demanded by each user, considering the minimum required pressure. The pressurized water systems have increased water efficiency since their implantation, but they also increased the consumed energy and therefore, the greenhouse gasses emissions. The present manuscript develops the proposal of the sustainable indicators that were selected through deep review. These indicators are related to social-cultural, economic, and environmental criteria. Furthermore as novelty, they were described and applied on a pressurized water network, complementing the energy indexes usually used in the energy audit. To reach the improvement of the sustainability in water systems, new strategies should be developed to improve all sustainability criteria, included the water and energy efficiency. These strategies were developed and analyzed by using of specific hydraulic software (i.e., EPANET and they were based on operation rules to estimate the hydraulic values (pressure and flow. The operation and the regulation strategies were applied on a particular case study, in which, the energy saving was 12.26%, the cost saving was 15.54%, the reduction of energy footprint of water was 15.04%, and the decrease of GHG was 12.26% although the increase of the distributed volume was 9.07%. Besides, the supply guarantee for both irrigation and urban water distribution systems was increased in the new proposal of water management. Finally, the proposal to replace of a pressure reduction valve by a sustainability recovery machine (e.g., pump working as turbine contributed with a generation of renewable energy equal to 103,710 kWh/year.

    Agriculture is the largest freshwater consumer, accounting for 70% of the world's water withdrawal. Water footprints (WFs) are being increasingly used to indicate the impacts of water use by production systems. A new methodology to assess WF of wine was developed in the framework of the V.I.V.A. project (Valutazione Impatto Viticoltura sull'Ambiente), launched by the Italian Ministry for the Environment in 2011 to improve the Italian wine sector's sustainability. The new methodology has been developed that enables different vines from the same winery to be compared. This was achieved by calculating the gray water footprint, following Tier III approach proposed by Hoekstra et al. (2011). The impact of water use during the life cycle of grape-wine production was assessed for six different wines from the same winery in Sicily, Italy using both the newly developed methodology (V.I.V.A.) and the classical methodology proposed by the Water Footprint Network (WFN). In all cases green water was the largest contributor to WF, but the new methodology also detected differences between vines of the same winery. Furthermore, V.I.V.A. methodology assesses water body contamination by pesticides application whereas the WFN methodology considers just fertilization. This fact ended highlights the highest WF of vineyard 4 calculated by V.I.V.A. if compared with the WF calculated with WFN methodology. Comparing the WF of wine produced with grapes from the six different wines, the factors most greatly influencing the results obtained in this study were: distance from the water body, fertilization rate, amount and eco-toxicological behavior of the active ingredients used.

    Estimate the health risks and benefits of mode shifts from car to cycling and public transport in the metropolitan area of Barcelona, Spain. We conducted a health impact assessment (HIA), creating 8 different scenarios on the replacement of short and long car trips, by public transport or/and bike. The primary outcome measure was all-cause mortality and change in life expectancy related to two different assessments: A) the exposure of travellers to physical activity, air pollution to particulate matter traffic fatality; and B) the exposure of general population to PM2.5, modelling by Barcelona Air-Dispersion Model. The secondary outcome was a change in emissions of carbon dioxide. The annual health impact of a shift of 40% of the car trips, starting and ending in Barcelona City, to cycling (n=141,690) would be for the travellers who shift modes 1.15 additional deaths from air pollution, 0.17 additional deaths from road traffic fatality and 67.46 deaths avoided from physical activity resulting in a total of 66.12 deaths avoided. Fewer deaths would be avoided annually if half of the replaced trips were shifted to public transport (43.76 deaths). The annual health impact in the Barcelona City general population (n=1,630,494) of the 40% reduction in car trips would be 10.03 deaths avoided due to the reduction of 0.64% in exposure to PM2.5. The deaths (including travellers and general population) avoided in Barcelona City therefore would be 76.15 annually. Further health benefits would be obtained with a shift of 40% of the car trips from the Greater Barcelona Metropolitan which either start or end in Barcelona City to public transport (40.15 deaths avoided) or public transport and cycling (98.50 deaths avoided).The carbon dioxide reduction for shifting from car to other modes of transport (bike and public transport) in Barcelona metropolitan area was estimated to be 203,251t/CO₂ emissions per year. Interventions to reduce car use and increase cycling and the use of

    2010-03-01

    Full Text Available Participation of stakeholders in planning processes is increasingly seen as an essential element in adaptive and integrated water management and sometimes a policy requirement from higher-level governance bodies. Despite an extensive literature on the advantages and disadvantages of public participation and criteria for effective participation, not much is known about how water managers should proceed in a given context. Water-management agencies have to face the challenge of effectively involving stakeholders in developing their water-management plans and must design and implement a balanced process approach among the available time, finances, organization, and facilitation without compromising their authority. This article presents a participatory planning process designed and implemented at Water Board "Hoogheemraadschap De Stichtse Rijnlanden" (HDSR in the center of The Netherlands. For a period of 2 yrs, these three groups were involved in various ways, participating in different types of meetings and workshops, using a range of participatory tools and techniques. The process and results of the three groups were monitored and evaluated using a tailored evaluation strategy. This paper analyzes the way the design and implementation of the process is perceived by both the conveners and participants and suggests practical lessons for water managers. Based on our case, it is argued that a careful process design, a thorough and continuous stakeholder analysis, building reflective workshops within and after the process, and ensuring experienced and qualified process leaders can greatly enhance the adaptive capacity and successful outcome of the participatory planning process.

    Alberich González, Joan

    2014-06-01

    Full Text Available Barcelona has been since many years ago the functional centre of a vast territory, beyond the strict scope of Catalonia. From this fact, the aim of the study is to determine whether the regional capital of Barcelona and the general process of tertiarisation, two phenomena almost contemporary, have reinforced its centrality and if they have done with greater intensity than in other cities from the Catalan urban system. In agreement with this, we have divided this work into two sections. The first one analyzes the evolution of jobs of Barcelona and the Catalan cities of over 50,000 inhabitants from the late 1980s and the first decade of the 21st century and their distribution by activity branches. The second part, as an example of this tertiarisation process, we analyze the functional change and valorisation of a Barcelona’s old obsolete industrial area for its renewal into an advanced tertiary sector use, known as district 22@.Barcelona es desde hace muchos años el centro funcional de un extenso territorio, que va más allá del ámbito estricto de Cataluña. A partir de esta realidad, el objetivo del trabajo es conocer si la capitalidad autonómica de Barcelona y el proceso general de terciarización, dos fenómenos casi contemporáneos, han reforzado su centralidad y si lo han hecho con mayor intensidad que en otras ciudades del sistema urbano catalán. De acuerdo con este planteamiento, hemos dividido este trabajo en dos apartados. El primero analiza la evolución de los puestos de trabajo y su distribución por ramas de actividad de Barcelona y las ciudades catalanas de más de 50.000 habitantes entre finales de la década de 1980 y la primera década del siglo XXI . La segunda parte, como un ejemplo de este proceso de terciarización, analiza el cambio funcional y la puesta en valor de un antiguo espacio industrial barcelonés en desuso, para su reconversión en uso del terciario avanzado, el llamado distrito 22@.

    2008-12-01

    Full Text Available Although modern European water policy follows a river basin approach where Member States have to cooperate in order to achieve a ‘good status’ of their water bodies, the obligations arising from the European water directives are to be achieved by each Member State individually. This situation creates problems when water pollution and water quantity problems cross borders. It is still unclear whether Member States can be held responsible for not achieving objectives due to causes (partly originating abroad. This article describes some of the legal instruments that water authorities have at their disposal to comply with the European water management obligations in case of transboundary water pollution and floods and thus shape transboundary river management. The article describes instruments to create, implement and enforce transboundary cooperation, and addresses the possibility of transboundary compensation if cooperation fails. Here, the focus is on a civil lawsuit before a domestic court.

  12. Peculiarities of tissue water fractional composition in case of experimental whole-body hyperthermia

    2015-09-01

    Full Text Available The present study, using proton nuclear magnetic resonance relaxation (NMR method, was undertaken to compare the water fractional composition in nature tissues (group 1 with those damaged by experimental whole-body hyperthermia (group 2. We measured longitudinal or “spin-lattice” (T1 and transverse or “spin-spin” (T2 relaxation times of protons of tissues (brain, the atria of the heart, the kidneys and the renal cortex from adult Wistar rats. The differences in T1, T2 and percentage of the intra- and extracellular water between group 1 and 2 were studied to help understand how the water moves in tissues at hyperthermia. The results of this study and the literature data allow to make conclusions about tissue water fractional composition in case of experimental whole-body hyperthermia: (1 fractional composition of water and the distribution of intra- and extracellular fluid in the tissue of the atria of the heart did not change (T1 and T2 relaxation times remained unchanged; (2 the crystalline water fraction increased in brain (longer T1 relaxation rate and shorter T2 relaxation rate. This is obstructing the exchange of protons between free and bound water in brain. Thus, loss of water by brain cells is prevented. The distribution between intra- and extracellular fluid in brain remained unchanged; (3 fraction of free water increased in renal tissue (simultaneous longer T1 and T2 relaxation rates by reducing the volume of extracellular fluid; (4 thick hydration layer of water (longer T1 relaxation rate, T2 remained unchanged was formed in the extracellular fluid of renal cortex. This water layer is formed around the sodium ions which concentration is increased in renal cortex tissue of rats from group 2. Аs a result, the amount of fluid secreted by kidneys is reduced, i.e. there is a retention of water in the body. The relevance of our research for the understanding of high temperatures’ adaptation mechanisms is discussed in this paper.

    2005-12-01

    Application of the Landsat TM/ETM+ signal over aquatic environment requires the retrieval of water-leaving radiance (Lw) from the total radiance recorded at the top-of-the-atmosphere (TOA) and thus of the water constituents' of interests. This paper compares the image-based atmospheric corrections such as empirical line method, COST method, and Spectral Shape Matching Method(SSMM) in the Landsat TM/ETM+ imagery, especially from Case-II waters around Korean peninsula. The SSMM which is simple and easy to implement on any satellite imagery relies on the assumption that spectral form of water-leaving radiance or reflectance for typical turbid or clear waters is nearly stable and provide a way to extract the path signal from the total signal recorded at the top of the atmosphere (LTOA). To assess the potential use of SSMM, several field campaigns were conducted in the Seamangeum area located at central western coastal area, KOREA corresponding with the Landsat-7 satellite's schedules. In situ observations were made from the coastal waters and land objects around the Seamangeum using ASD field spectroradiometer, consisting of Chl, Ap, SS, aDOM, F(d) . Firstly, SSMM was applied using the nearly stable spectrum from ocean area and the results were verified with in situ water-leaving spectra. Secondly, the SSMM was applied using spectra obtained from the land area and the results were compared with that from using stable ocean water-leaving radiance spectra. Finally, the performance of SSMM was compared with Empirical Line Method and COST model. The findings revealed that SSMM produced spectra consistent with in situ data, whereas other two methods sometimes yielded significantly high errors in these areas.

    Polychlorinated biphenyls (PCBs) are a class of aryl halides widely distributed in the environment. Although production has virtually ceased, and most industrial applications (capacitors, transformers, hydraulic fluids, lubricants, etc) are severely restricted, they are one of the most ubiquitous and persistent environmental pollutants. Several toxic effects caused by PCBs have been described including: liver enlargement, hepatomegalocytosis, acne, lymphoid atrophy, immunosuppression, tumor promotion, porphyria. This work continues the authors' previous reports about organochlorine residues in human tissues of some Spanish populations, that showed high levels of some residues, specially of hexachlorobenzene (HCB). PCBs pattern and concentration in the adipose tissue of the inhabitants of an urban and industrial area (Barcelona) were determined.

    Bech, Joan; Sola, Yolanda; Ossó, Albert; Lorente, Jeroni

    2014-05-01

    This study presents an analysis of a 14-year data set of thirty-minute averaged experimental UVI values derived from ground-based broadband irradiance measurements, satellite-derived total ozone observations and total solar radiation recorded in Barcelona (NE Spain). Most maximum daily UVI values do occur at noon (82% of cases between 11:30 to 13:00 UTC). Considering all seasons, the maximum daily UVI presents a bimodal, approximately symmetrical, frequency distribution with a maximum around UVI class 2 (22%) and UVI 7 and 8 classes (23%) while June median presents a value of 8.2. According to attenuation criteria there is a preponderance of Clear sky days (77%) compared to Broken (22%) and Overcast (8%) conditions, which concentrate mostly in October, November and December (reaching 20% of days). An additional classification in terms of World Health Organisation UVI intensity categories indicates that 40% of days exceeded the lower threshold of UVI category Moderate (UVI values above 5.5), from them 21% of days had UVI values considered Very High (above 9.5) and one single case was classified as Extreme (UVI above 10.5). UVI values above 7.5 were found under Broken sky conditions in June, July and August. Additionally UVI diurnal daily cycles have also been analyzed in terms of selected percentile values and maximum levels. Under all sky-conditions UVI median values exceed the lower threshold of category High (5.5) from April to late August around noon (in June from 10:00 to 14:30 UTC). These results provide an exhaustive quantitative description of average and extreme values of experimental UVI values observed in the region and can be of interest for a wide range of applications, including ground-based UV modelling through the use of radiative transfer models, trend analysis or verification of UVI forecasts.

    Sediments have long been recognised as a sink for many contaminants like polycyclic aromatic hydrocarbons (PAHs) and tributyltin (TBT), which by virtue of their nature can strongly adsorb onto sediments affecting the benthic community inhabiting them. Using geographical information systems, this study reports and combines the results of several already existing studies along Barcelona harbour in order to assess the potential ecological impacts of these contaminants on the benthos of the harbour ecosystem. Chemical analysis indicated low to moderate contents of PAHs and high contents of TBT in sediments in Barcelona harbour. Comparison against existing sediment quality guidelines (SQGs) indicated that acutely toxic effects would not be expected for PAHs but for TBT, which represents a serious environmental threat for the benthic community. Benthos surveys revealed a deterioration of the benthic community throughout the harbour, especially in the inner port. - A possible correlation exists between TBT concentration in sediments and ecological effects on benthos in Barcelona harbour.

    Full Text Available With the effective control of point source (PS pollution accomplished, water pollution problems caused by non-point source (NPS pollution have increased in recent years. The worsening agricultural NPS pollution has drawn the attention of the Chinese Government and researcher scientists and has resulted in the often mentioned “three red lines” on water resources management. One of the red lines is to control water pollution within a rational range. The Agricultural NPS pollution, which includes pollution from housing, and from livestock and crop production, is the main source. Based on the NPS pollution statutes, an index system for integrated evaluation of water quality, and a zoning scheme for rural water conservation were established. Using the method of one-dimensional Euclidean distance, this country is divided into 9 sub-zones at the provincial level, which are the first level zones. The zoning themes include natural resources, socio-economic development, water use efficiency, and pollutants emission intensity. According to pollution types of livestock, agriculture, or both, the first level zones are divided into 25 second level zones. The third class zoning is divided also based on pollution intensity of total nitrogen (TN, total phosphorus (TP, ammonia nitrogen (NH3-N, chemical oxygen demand (COD, and biochemical oxygen demand (BOD. On the basis of the second level zoning, there were formed 70 rural water conservation third level zones. This case study in the Ashihe river watershed indicated that the main pollution sources are consistent with the zoning research result, and this zoning has shown a good way to guide the agricultural NPS pollution control in not only the wide rural area of China but also other parts of the world.

    Although the water management sector is often characterized as resistant to risk and change, urban areas across the United States are increasingly interested in creating opportunities to transition toward more sustainable water management practices. These transitions are complex and difficult to predict - the product of water managers acting in response to numerous biophysical, regulatory, political, and financial factors within institutional constraints. Gaining a better understanding of how these transitions occur is crucial for continuing to improve water management. This paper presents a replicable methodology for analyzing how urban water utilities transition toward sustainability. The method combines standardized quantitative measures of variables that influence transitions with contextual qualitative information about a utility's unique decision making context to produce structured, data-driven narratives. Data-narratives document the broader context, the utility's pretransition history, key events during an accelerated period of change, and the consequences of transition. Eventually, these narratives should be compared across cases to develop empirically-testable hypotheses about the drivers of and barriers to utility-level urban water management transition. The methodology is illustrated through the case of the Miami-Dade Water and Sewer Department (WASD) in Miami-Dade County, Florida, and its transition toward more sustainable water management in the 2000s, during which per capita water use declined, conservation measures were enacted, water rates increased, and climate adaptive planning became the new norm.

    Full Text Available This work situates flamenco, anti-flamenquismo, and national identities in Barcelona during the three decades leading up to the Civil War and unravels what the contested musical spaces meant for Catalan nationalists. Through their attacks on cafés cantantes and their promotion of the sardana and choral societies, Catalan nationalists posited an identity that denied the industrial system that Catalans themselves created and that effaced the problems that came with it. In the end, however, the Catalan nationalists’ attempts to render flamenco performers and their performances obsolete failed because foreigners and profit-seeking Catalans and Andalusians kept stoking the flames of an exoticized Barcelona.

    We aimed to analyse the prevalence of having multiple lifestyle risk behaviours (LRB) and the potential relationship between excess weight (including overweight and obesity) and cumulative multiple LRB among adolescents in Barcelona, Spain. A cross-sectional study was performed among a representative sample of 3,114 secondary school students in Barcelona. Height and weight were objectively measured and excess weight was defined in accordance with World Health Organization criteria. Information on screen time, breakfast, physical activity and sleep duration was obtained through a self-administered questionnaire. More than 80% of the students had at least two LRBs. In compulsory schooling, the adjusted prevalence ratio (aPR) of excess weight increased with a higher number of reported LRBs (four LRBs: aPR=1.56; 95% confidence interval: 1.19-2.05). These results highlight the importance of a multiple-behaviour approach in preventive programmes aimed at reducing adolescent obesity. Copyright © 2017 SESPAS. Publicado por Elsevier España, S.L.U.

    Full Text Available Purpose: the work presented is a descriptive, contextual and detailed analysis of the activity, and the conclusions developed in the first international accounting conference held in Barcelona. The 6th International Conference on Accounting which took place in Barcelona coinciding with the International Exhibition of 1929, was organised by the Association Internationale de Comptabilité of Brussels. This association proposed holding regular meetings to discuss and study technical accounting and economic issues related to that time. Approach: the originality of the work lies in being an analytical description of the original documents prepared by the Association of Accountants of Catalonia about the conference. Findings/Originality: this study allows redoing assumptions made in previous works, because the documents before this work were contradictory regarding dates, facts and some of the content covered. Limitations: the biggest limitation of the work comes from the lack of written documentation existing on this conference. Value: the present study continues the research on topics of history of accounting in Catalonia. It is expected to complement this work by a deeper analysis of the contents and the topics covered in the papers presented at the conference, and by linking them with the theoretical accounting lines existing at that time.

    The Food Health Quality Research Program (Investigación de la Calidad Sanitaria de los Alimentos [ICSA]) of the Public Health Agency of Barcelona (Agencia de Salud Pública de Barcelona [ASPB]) was initiated in 1984 to carry out surveillance of certain chemical and microbiological parameters related to the sanitary and safety of foods sold in the city. The present article analyzes the importance of health surveillance and provides details of the uses of the ICSA program. The main aim of this program is to evaluate whether marketed foods comply with the absence and/or established tolerance levels of specific parameters. Nevertheless, the program is able to incorporate or suppress parameters or foods that pose emerging dangers or interests not represented in current legislation. Besides, the program not only obtains a view of the parameters studied at a specific time period in each report, but also accumulates data over time, allowing risk assessment, calculation of dietary intake of contaminants, analysis of tendencies, and evaluation of the effectiveness of regulations to reduce contaminants. The program can also help in the planning of food control programs. The information obtained is disseminated nationally and internationally and is included in dossiers of contaminants issued by national and European health agencies. This demonstrates that a locally-developed surveillance system can have a wider scope and broader objectives and can provide useful information for managers, administrations, economic operators and consumers.

    2016-08-01

    In order to contribute to the sustainability of the outdoor environment, knowledge about the urban thermal bioclimate should be transferred into climatic guidelines for planning. The general framework of this study responds to the need of analyzing thermal bioclimate in Mediterranean climate regions and its influence as an urban design factor. The paper analyzes the background of the urban climate and thermal bioclimate conditions in Barcelona (Spain), through the effect of shade conditions and wind speed variations. Simulations of shade and wind speed variations were performed to evaluate changes in thermal bioclimate due to modifications in urban morphology. Air temperature, relative humidity, wind speed, and solar radiation for the period from January, 2001 to January, 2015 were used to calculate physiologically equivalent temperature (PET) using the RayMan model. The results demonstrate that shade is the most important strategy to improve urban microclimatic conditions. In Barcelona, human thermal comfort conditions can be improved by shade and wind speed increase in terms of PET above 23 °C and by a wind speed decrease for thresholds of PET below 18 °C. Heat stress situations can be mitigated by shade and wind speed increase in conditions above 35 and 45 °C, respectively. The results of the study are an important contribution for urban planners, due to their possibilities and potential for the description of microclimatic conditions in Mediterranean climate regions. The knowledge is useful for improved human thermal comfort conditions, from the suitable configuration of urban form and architecture.

    Full Text Available This paper examines Ildefons Cerdà’s 1860 Plan for the Urban Expansion of Barcelona; specifically, how and why it was conceived in a unique way, in which the provision of services to the population was an important part. Cerdà based his expansion proposal on an in depth socio statistical study of old Barcelona’s population conditions. The high mortality rates of the working class population and poor health and education conditions pushed Cerdà to design a new type of urban planning, which he defined as “urbanism”. In his proposal for the new city, he planned the location of services such as marketplaces, schools and hospitals. The first part of this paper introduces the urban and political preconditions of Barcelona and the statistics on which Cerdà based his contribution. The second part uses location theory and a geographic information system (GIS to analyse the pattern of location and the population served by markets and hospitals. In addition, topographic maps from 1926 and 1975 are used to study the development of the expansion up to when it was fully developed. The evolution of the city differed from Cerdà’s proposal, partly due to unexpected increases in population density, the built environment, and higher amounts of building occupation. Nevertheless, Cerdà’s layout of streets and avenues has prevailed.

    This study is aimed to describe the differences in mortality among the 38 wards of the city of Barcelona for the period 1983-89. Mortality data for years 1983 to 1989 came from the death certificates. The indicators used for the 38 city wards and the 10 city districts were: Comparative Mortality Figure, Ratio, Ratio of Potential Years of Life Lost, and Life Expectancy at birth. A descriptive analysis of these indicators by wards and district is offered; a cluster analysis based on these indicators was also performed. Wards from the same district are considered homogeneous for a given indicator, when all ward's values are higher, equal or lower to district average. The ward with the most unfavourable indicators and worst situation was Montjuïc, an exponent of shanty town problems until few years ago and located near the centre. Next in ranking, from worst to best situation, did appear the four wards of the city centre district, the old historical quarter. Other wards with high mortality rates were some peripheral areas, nearly all built recently such as Ciutat Meridiana, Bon Pastor and Zona Franca, and also other old wards, such as Poble Sec. Cluster analysis classified the wards with higher mortality in several different clusters, clearly split from the other more homogeneous wards. Five of 10 districts have been considered as homogeneous. This study has allowed a deeper knowledge of the geographical distribution of mortality in the city of Barcelona, until now analysed by city districts.

    Full Text Available This paper analyses a case study undertaken in 2001 of a Victorian public sector water utility to examine theimplications of public sector ‘modernisation’ reforms of the 1980s and 1990s for the adoption ofenvironmental accounting (EA procedures within the Victorian water industry. Legislative reforms haveresulted in the allocation of overhead costs for the purpose of segmented reporting and to measure the ‘fullcost’ of departments. This was consistent with the “managerialist”, “marketization” and “strategic” phases ofpublic sector ‘modernisation’ reforms, but did not measure the full economic (environmental cost. Theapplication of full cost recovery for the purpose of efficiency was further evidence of the impact of publicsector modernisation reforms but did not extend to the recovery of externalities. Private environmental costswere traced and integrated into direct cost categories, consistent with the philosophy of managerialism. Costswere measured for the purposes of promoting the contracting out of selected services and functions. Therewas limited adoption of environmental accounting practices, due to the absence of environmental accountingmeasurement guidelines. Staff interviewed recognized the importance of environmental issues, but were yetto appreciate the benefits of adopting EA practices. Subsequent to the case study, the Victorian governmentintroduced legislation that required water authorities to make provisions for environmental contributions, astep towards accounting for environmental externalities. This was the beginning of the “sustainability” phaseof public sector ‘modernisation’ reforms.

    Sudden pressure increases in the penstock or spiral case of a hydraulic turbine are the effect of sudden flow variation that occur during transient processes of type opening / closing or load rejection of the hydro unit. The consequence of the pressure rise in the spiral case and penstock is the water hammer phenomenon, whose effects can be devastating in some cases, up to breaking pipes and calamities produced in the area. This paper aims to analyze the method of calculation of the maximum pressure values that might occur in load rejection situations to a hydraulic turbine, in spiral case and in penstock, conditioned by the limiting of the values of the over speed and measures of limiting the increase in pressure in conjunction with limiting the increase in speed in these specific processes. As an example, we studied and analyzed the situation of a hydroelectric power plant equipped with a 7.8 MW Francis turbine without pressure regulator and the inflow surge. The results of analytical calculation overlaid on the experimental measurements performed during the performance tests of the hydro unit lead to the conclusion that the calculation algorithm proposed has been chosen correctly and the 2-stage closing law of the wicket gate promoted in this case is effective in such situations.

    This document discusses results of applying the Integrated Ground-Water Monitoring Strategy (the Strategy) to actual waste sites using existing field characterization and monitoring data. The Strategy is a systematic approach to dealing with complex sites. Application of such a systematic approach will reduce uncertainty associated with site analysis, and therefore uncertainty associated with management decisions about a site. The Strategy can be used to guide the development of a ground-water monitoring program or to review an existing one. The sites selected for study fall within a wide range of geologic and climatic settings, waste compositions, and site design characteristics and represent realistic cases that might be encountered by the NRC. No one case study illustrates a comprehensive application of the Strategy using all available site data. Rather, within each case study we focus on certain aspects of the Strategy, to illustrate concepts that can be applied generically to all sites. The test sites selected include:Charleston, South Carolina, Naval Weapons Station,Brookhaven National Laboratory on Long Island, New York,The USGS Amargosa Desert Research Site in Nevada,Rocky Flats in Colorado,C-Area at the Savannah River Site in South Carolina, andThe Hanford 300 Area.A Data Analysis section provides examples of detailed data analysis of monitoring data.

    Algal blooms can be harmful and a nuisance in a variety of aquatic ecosystems, including reservoirs and lakes. Cyanobacterial(blue-green algae) harmful algal blooms are notorious for producing both taste-and-odor compounds and potent toxins that may affect human health. Taste–and-odor episodes are aesthetic problems often caused by cyanobacterial-produced organic compounds (geosmin and methylisoborneol) and are common in reservoirs and lakes used as source water supplies. The occurrences of these taste-and-odor compounds and toxins (like microcystin) can be sporadic and vary in intensity both spatially and temporally. Recent publications by the U.S. Geological Survey address this complexity and provide protocols for cyanotoxin and taste-and-odor sampling programs. A case study conducted by the U.S. Geological Survey, in cooperation with Spartanburg Water, monitored two mesotrophic reservoirs that serve as public drinking water supplies in South Carolina. Study objectives were (1) to identify spatial and temporal occurrence of the taste-and-odor compound geosmin and the cyanotoxin microcystin and (2) to assess the associated limnological conditions before, during, and after these occurrences. Temporal and spatial occurrence of geosmin and microcystin were highly variable from 2007 to 2009. The highest geosmin concentrations tended to occur in the spring. Microcystin tended to occur in the late summer and early fall, but occurrence was rare and well below World Health Organization guidelines for finished drinking water and recreational activities. No current U.S. Environmental Protection Agency standards are applicable to cyanotoxins in drinking or ambient water. In general, elevated geosmin and microcystin concentrations were the result of complex interactions between cyanobacterial ⬚community composition, nutrient availability, water clarity, hydraulic residence time, and stratification.

    Full Text Available Contribution of the Danube tributaries in pollution of its water. Case Study: Evaluation of the Eșelnița water river quality. Developed on the south-eastern side of Almãjului Mountains, Eşelniţa drainage basin neighbours upon the following basins: upon S – SV with Mala, upon SV - V with Mraconia, upon V - NV with Berzasca, upon NV - NNE with Nera and on the NNE – SE direction with Cerna. The basin has a surface of 77 km2 and present a 5th degree hydrographic network according to Horton - Strahler ranking system, tributary to Danube by means of Eşelniţa main collector. Developed in a mountain landscape, the basin presents different levels held between minimum altitude of 64 m at the confluence with the Danube and maximum altitude of 1107 m, thus presenting a difference of 1043 m. Geological formations within the basin belong largely the Danubian Domain, so in central and upper courses, these are represented by a crystalline foundation and by magmatic rocks of intrusive nature. But in the lower course, there are both crystalline and the sedimentary formations, last being integrated to Orşova depression and whose presence is related to the evolution of the Danube. The morphometrical indices of Eşelniţa basin allow to distinguish two different sectors: a higher sector, mountainous high energy relief, under the terms of a early fragmentation and a depresional sector with a low energy relief but with a more intense fragmentation on the basis of sedimentary rocks existence.

    Full Text Available The traditional concepts of water resource development and utilization have caused serious hydrological and environmental issues in some regions. In addition, policy issues in China have led to a severe water crisis. The quantitative accounting of water resources is a theoretical approach to solving these problems. In this paper, 13 indicators were selected from four classes, including resources, the environment, society, and efficiency, and a case study of Jinan, Shandong Province, was performed using a set pair analysis model to calculate the water resource assets from 2011–2015. In previous methods of water resource accounting, the water quality was not considered; therefore, the loss coefficient of water resource assets was proposed to improve the reliability of accounting. According to the relationships among the unit price of water, water quantity, and water quality, physical and quantitative accounting methods were used to create water balance sheets from 2011–2015. The calculation results showed that the physical change in water resource assets in Jinan City was −30 million m 3 , and water resource assets initially increased and then decreased. In 2011, 2012, 2013, 2014, and 2015, water resource assets totalled 36.5 million USD, 45.9 million USD, 66.7 million USD, 35.5 million USD, and 37.5 million USD, respectively (at 6.4588, 6.3125, 6.1932, 6.2166, 6.2284 USRMB, respectively. This initial accounting provides quantitative and physical support for the improved management of water resources.

    The North Borneo state of Sabah is known worldwide for its beautiful islands and dive sites. Local hospitals deal with a number of marine-related injuries, including marine fauna envenomation by Scorpaenidae and Synanceiidae families of fish. We report a case of a tourist who presented with excruciating pain on her right foot after stepping on a stonefish. Despite being given parenteral analgesia and regional anaesthesia, the pain persisted. Her pain improved after she soaked her foot in hot water for about 30 minutes. No further treatment was required. We reviewed the literature comparing this inexpensive mode of treatment with other conventional treatments. We also explored the possibility of using hot water immersion for treatment of envenomation by other types of marine animals.

    Full Text Available Water intoxication is a rare condition characterised by overconsumption of water. It can occur in athletes engaging in endurance sports, users of MDMA (ecstasy, and patients receiving total parenteral nutrition. This case outlines water intoxication in a patient with psychogenic polydipsia. When the kidney’s capacity to compensate for exaggerated water intake is exceeded, hypotonic hyperhydration results. Consequences can involve headaches, behavioural changes, muscular weakness, twitching, vomiting, confusion, irritability, drowsiness, and seizures. Cerebral oedema can lead to brain damage and eventual death. In this case, psychogenic polydipsia led to significant hyponatraemia, cerebral oedema, and tonic-clonic seizures. Differential diagnoses for hyponatraemia are outlined. The aetiology of psychogenic polydipsia is uncertain, but postulated hypotheses are explored. Psychogenic polydipsia occurs in up 20% of psychiatric patients and this case serves to remind us to be cognizant of water overconsumption.

    In Ouargla's oasis, which is one of urban conglomerations of Algerian Sahara, the exploitation and/or the overexploitation of the deep aquifers of continental intercalary and of complex terminal that contain waters of mediocre quality (salty and hot), and the rejection of waters of drainage, urban residual waters and non-treated industrial waters are responsible, at the same time, of the degradation of the quality of waters of the groundwater and its upwelling. This situation has led to: (i) the deterioration of the environment and (ii) the deterioration of constructions (houses, roads, etc…). The present paper consists in giving in detail the causes of the water upwelling of phreatic aquifers in our regions, the quality of water of this aquifer and the influence of the quality of phreatic aquifer water on environment and constructions in Ouargla city by analyzing water samples of 10 points of this town.

  13. Fuzzifying historical peak water levels: case study of the river Rhine at Basel

    2016-04-01

    Hydrological information comes from a variety of sources, which in some cases might be non-precise. In particular, this is an important issue for the available information on water stages during historical floods. An accurate estimation of the water level profile, together with an elevation model of the riverbed and floodplain areas is fundamental for the hydraulic reconstruction of historical flood events, allowing the back calculation of flood peak discharges, velocity and erosion fields, damages, among others. For the greatest floods during the last 1700 years, Wetter et al. (2011) reconstructed the water levels and historical discharges at different locations in the old city centre from a variety of historical sources (stone marks, official documents, paintings, etc). This work presents a model for the inherent unpreciseness of these historical water levels. This is, with the arithmetics of fuzzy numbers, described by their membership functions, in a similar fashion as the probability density function describes the uncertainty of a random variable. Additional to the in-site collected water stages from floodmarks and other documentary evidence (e.g. preserved in narratives and newspaper flood reports) are prone to be modeled in a fuzzy way. This study presents the use of fuzzy logic to transform historical information from different sources, in this case of flood water stages, into membership functions. This values might then introduced in the mathematical framework of Fuzzy Bayesian Inference to perform the statistical analyses with the rules of fuzzy numbers algebra. The results of this flood frequency analysis, as in the traditional non-fuzzy way, link discharges with exceedance probabilities or return periods. The main difference is, that the modeled discharge quantiles are not precise values, but fuzzy numbers instead, represented by their membership functions explicitly including the unpreciseness of the historical information used.

    Full Text Available Water Saving Devices (WSDs sustain demands for potable water, soften impacts on supply systems and inflict a positive effect on wastewater treatment systems. This study evaluated the effect of some WSDs in Oman. A questionnaire survey and some case studies were used. The survey results revealed that the pipe line system network for water supply accounted for about 67.7%, whereas the rest mainly use tankers. Around 37.2% of the participants received consumed 25000 - 45000 liters per household per month. Case studies showed no significant difference in household water usage before and after installation of WSDs due to pre-installed aerators. Toilet bags and dual flush toilets were not effective promoting users to flush. However, WSDs were significantly effective in restaurants, mosques, hotels and government buildings. Water consumption in shopping centres and hospitals slightly decreased. Retrofitting programs that involve replacement of existing plumbing equipment and residential water audit programs are recommended.

    The paper analyses the profitability of the use of Drain Water Heat Recovery units. An original simulation model was used for this purpose, and a detached residential building located in Poland was selected as the test facility. The conducted analysis proved that the type of the hot water heater has decisive influence on the profitability level of such an investment. Application of the abovementioned technology is particularly profitable, when water is heated with the use of an electrical device. When the energy source in the system is a gas water heater, the obtained calculation results are not as favourable, and the period of investment return in many cases exceeds the expected service life of these devices. Moreover, the analysis demonstrated that the potential energy savings, and thus also the financial savings, may be in both cases increased as a result of simultaneous intake of water from various water taps.

    During the process of water injection production in oilfield, when water cuts into the mudstone, as a result, large numbers of casings are damaged because of mudstone's creep characteristic. In order to analyze this phenomenon, the uniaxial compression experiments and creep experiments of mudstone from Daqing Oil Field under different saturation conditions were done, it was studied that how the mudstone's mechanical parameters and creep characteristic would change with the increment of water contents. The results indicate that the rock strength and elastic modulus are decreased rapidly with the increment of water contents, on the other hand, the creep strain and steady state creep strain rate are increased with the increment of water contents, and also the steady state creep strain rate is enhanced with the increment of deviatoric stress. Through the creep characteristic curves, a nonlinear creeping constitutive equation of mudstone considering the changes of water contents was established. In the deep stratum of the oilfield, the calculation model of casing-cement sheath-mudstone was built, based on the experiment results of mudstone and its creep constitutive equation, mudstone's creep pressure with time under different water contents was simulated. The simulation results show that the increasing water content accelerates the incremental rate of the creep pressure of mudstone, so the time of reaching yield state of casing will descend greatly, which means service time of casing becomes much shorter.

    2006-01-01

    Full Text Available Every year, flash floods cause economic losses and major problems for undertaking daily activity in the Catalonia region (NE Spain. Sometimes catastrophic damage and casualties occur. When a long term analysis of floods is undertaken, a question arises regarding the changing role of the vulnerability and the hazard in risk evolution. This paper sets out to give some information to deal with this question, on the basis of analysis of all the floods that have occurred in Barcelona county (Catalonia since the 14th century, as well as the flooded area, urban evolution, impacts and the weather conditions for any of most severe events. With this objective, the identification and classification of historical floods, and characterisation of flash-floods among these, have been undertaken. Besides this, the main meteorological factors associated with recent flash floods in this city and neighbouring regions are well-known. On the other hand, the identification of rainfall trends that could explain the historical evolution of flood hazard occurrence in this city has been analysed. Finally, identification of the influence of urban development on the vulnerability to floods has been carried out. Barcelona city has been selected thanks to its long continuous data series (daily rainfall data series, since 1854; one of the longest rainfall rate series of Europe, since 1921 and for the accurate historical archive information that is available (since the Roman Empire for the urban evolution. The evolution of flood occurrence shows the existence of oscillations in the earlier and later modern-age periods that can be attributed to climatic variability, evolution of the perception threshold and changes in vulnerability. A great increase of vulnerability can be assumed for the period 1850–1900. The analysis of the time evolution for the Barcelona rainfall series (1854–2000 shows that no trend exists, although, due to changes in urban planning, flash-floods impact

    2017-04-01

    The impact of extremely warm episodes on health has been analysed by a large number of studies conducted in different countries and cities, showing that heat waves events (HWE) can cause an abrupt increase in mortality. A HWE was defined as a 7-day sequence following a key-day labelled by the 95th percentile of Barcelona daily mortality (see Peña et al., 2015). The aim of this study is to identify synoptic patterns associated to HWE in Barcelona over the 21st century and evaluate the impact and possible mitigations. To achieve it, a multivariate analysis (MVA) integrating different atmospheric levels (sea level pressure, temperature at 850 hPa and geopotential at 500 hPa) was undertaken. The observed data used for this study was the 20th Century Reanalysis. The Max Planck Institute Earth system model was used to study two scenarios (RCP 4.5 and RCP 8.5) during the 21st century. The model was calibrated given the variability in the climate scenario, using the Quantile-Quantile mapping transformation (Q-Q). The MVA applied to the observed period (1990-2015) distinguish three main synoptic patterns: two dynamic configurations produced by southern fluxes related to an Atlantic low, associated with HWE recorded in southern Europe, and a third pattern identified by a stagnation situation related to persistent anticyclone periods. These patterns were also detected in the control simulated period (1961-2005) after the Q-Q calibration, preserving, therefore, the climatic variability: the number of HWE during the warm period (1990-2005) is twice more than during the cold period (1976-1989) due to an intensification of the warm masses. In the RCP 4.5 scenario (2006-2100 period) a positive and significant trend is shown in synoptic patterns which provoke HWE in Barcelona, especially during August; in the RCP 8.5 scenario there is no significant trend, but the intensification of the warm masses is higher.

    Full Text Available Sources and evolution of ultrafine particles were investigated both horizontally and vertically in the large urban agglomerate of Barcelona, Spain. Within the SAPUSS project (Solving Aerosol Problems by Using Synergistic Strategies, a large number of instruments was deployed simultaneously at different monitoring sites (road, two urban background, regional background, urban tower 150 m a.s.l., urban background tower site 80 m a.s.l. during a 4 week period in September–October 2010. Particle number concentrations (N>5 nm are highly correlated with black carbon (BC at all sites only under strong vehicular traffic influences. By contrast, under cleaner atmospheric conditions (low condensation sink, CS such correlation diverges towards much higher N/BC ratios at all sites, indicating additional sources of particles including secondary production of freshly nucleated particles. Size-resolved aerosol distributions (N10–500 as well as particle number concentrations (N>5 nm allow us to identify three types of nucleation and growth events: (1 a regional type event originating in the whole study region and impacting almost simultaneously the urban city of Barcelona and the surrounding urban background area; (2 a regional type event impacting only the regional background area but not the urban agglomerate; (3 an urban type event which originates only within the city centre but whose growth continues while transported away from the city to the regional background. Furthermore, during these clean air days, higher N are found at tower level than at ground level only in the city centre whereas such a difference is not so pronounced at the remote urban background tower. In other words, this study suggests that the column of air above the city ground level possesses the optimal combination between low CS and high vapour source, hence enhancing the concentrations of freshly nucleated

    2014-01-01

    Background Household water treatment (HWT) can improve drinking water quality and prevent disease if used correctly and consistently by vulnerable populations. Over 1.1 billion people report treating their water prior to drinking it. These estimates, however, are based on responses to household surveys that may exaggerate the consistency and microbiological performance of the practice—key factors for reducing pathogen exposure and achieving health benefits. The objective of this study was to examine how HWT practices are actually performed by households identified as HWT users, according to international monitoring standards. Methods and Findings We conducted a 6-month case study in urban (n = 117 households) and rural (n = 115 households) Peru, a country in which 82.8% of households report treating their water at home. We used direct observation, in-depth interviews, surveys, spot-checks, and water sampling to assess water treatment practices among households that claimed to treat their drinking water at home. While consistency of reported practices was high in both urban (94.8%) and rural (85.3%) settings, availability of treated water (based on self-report) at time of collection was low, with 67.1% and 23.0% of urban and rural households having treated water at all three sampling visits. Self-reported consumption of untreated water in the home among adults and children water of self-reported users was significantly better than source water in the urban setting and negligible but significantly better in the rural setting. However, only 46.3% and 31.6% of households had drinking water water quality. The lack of consistency and sub-optimal microbiological effectiveness also raises questions about the potential of HWT to prevent waterborne diseases. PMID:25522371

    Household water treatment (HWT) can improve drinking water quality and prevent disease if used correctly and consistently by vulnerable populations. Over 1.1 billion people report treating their water prior to drinking it. These estimates, however, are based on responses to household surveys that may exaggerate the consistency and microbiological performance of the practice-key factors for reducing pathogen exposure and achieving health benefits. The objective of this study was to examine how HWT practices are actually performed by households identified as HWT users, according to international monitoring standards. We conducted a 6-month case study in urban (n = 117 households) and rural (n = 115 households) Peru, a country in which 82.8% of households report treating their water at home.

    In many Mediterranean islands with limited surface water resources, the growth of agricultural and touristic sectors, which are the main water consumers, highly depends on the sustainable water resources management. This work highlights the crucial role of groundwater footprint (GF) as a tool for the sustainable management of water resources, especially in water scarce islands. The groundwater footprint represents the water budget between inflows and outflows in an aquifer system and is used as an index of the effect of groundwater use in natural resources and environmental flows. The case study presented in this paper is the island of Crete, which consists of 11 main aquifer systems. The data used for estimating the groundwater footprint in each system were groundwater recharges, abstractions through 412 wells, environmental flows (discharges) from 76 springs and 19 streams present in the area of study. The proposed methodology takes into consideration not only the water quantity but also the water quality of the aquifer systems and can be used as an integrated decision making tool for the sustainable management of groundwater resources. This methodology can be applied in any groundwater system. The results serve as a tool for assessing the potential of sustainable use and the optimal distribution of water needs under the current and future climatic conditions, considering both quantitative and qualitative factors. Adaptation measures and water policies that will effectively promote sustainable development are also proposed for the management of the aquifer systems that exhibit a large groundwater footprint.

    Full Text Available Low impact development (LID is a relatively new concept in land use management that aims to maintain hydrological conditions at a predevelopment level without deteriorating water quality during land development. The United States Environmental Protection Agency (USEPA developed the System for Urban Stormwater Treatment and Analysis Integration model (SUSTAIN to evaluate the performance of LID practices at different spatial scales; however, the application of this model has been limited relative to LID modeling. In this study, the SUSTAIN model was applied to a Taiwanese watershed. Model calibration and verification were performed, and different types of LID facilities were evaluated. The model simulation process and the verified model parameters could be used in other cases. Four LID scenarios combining bioretention ponds, grass swales, and pervious pavements were designed based on the land characteristics. For the SUSTAIN model simulation, the results showed that pollution reduction was mainly due to water quantity reduction, infiltration was the dominant mechanism and plant interception had a minor effect on the treatment. The simulation results were used to rank the primary areas for nonpoint source pollution and identify effective LID practices. In addition to the case study, a sensitivity analysis of the model parameters was performed, showing that the soil infiltration rate was the most sensitive parameter affecting the LID performance. The objectives of the study are to confirm the applicability of the SUSTAIN model and to assess the effectiveness of LID practices in the studied watershed.

    The sustainable urban water management system is likely to be characterised by complex and flexible governance arrangements, increased inter-organisational interaction and wide stakeholder participation, which contrasts significantly with the traditional approach. Recently there has been significant financial investment in urban water reform, however the reforms have not been as successful as anticipated and numerous institutional barriers remain. Understanding and assessing institutional capacity is central to addressing institutional impediments. Institutional capacity comprises individual, intra- and inter-organisational and external rules and incentives capacities. This paper reports on the first case study of a social research project that aims to develop an institutional capacity assessment framework. Empirical data from semi-structured interviews with 59 water industry experts in Sydney, Australia, and a broad literature survey were used. The key capacity attributes identified could form the basis of an institutional capacity assessment tool and reveal common and differing attributes across stakeholder groups which provide insight into stakeholder relations. Synthesis of the results revealed that intra- and inter-organisational capacities were facing particular challenges and should be explicitly addressed in reform, policy and capacity development initiatives.

    Nosocomial outbreaks of Legionnaires disease have been linked to contaminated water in hospitals. Immunocompromised patients are particularly vulnerable and, when infected, have a high mortality rate. We report the investigation of a cluster of cases of nosocomial pneumonia attributable to Legionella pneumophila serogroup 1 that occurred among patients on our stem cell transplantation unit. We conducted a record review to identify common points of potential exposure, followed by environmental and water sampling for Legionella species from those sources. We used an air sampler to in an attempt to detect aerosolized Legionella and pulsed-field gel electrophoresis to compare clinical and environmental isolates. The most likely sources identified were the water supply in the patients' rooms and a decorative fountain in the radiation oncology suite. Samples from the patients' rooms did not grow Legionella species. Cultures of the fountain, which had been restarted 4 months earlier after being shut off for 5 months, yielded L. pneumophila serogroup 1. The isolates from both patients and the fountain were identical by pulsed-field gel electrophoresis. Both patients developed pneumonia within 10 days of completing radiation therapy, and each reported having observed the fountain at close range. Both patients' infections were identified early and treated promptly, and both recovered. This cluster was caused by contamination of a decorative fountain despite its being equipped with a filter and ozone generator. Fountains are a potential source of nosocomial Legionnaires disease despite standard maintenance and sanitizing measures. In our opinion, fountains present unacceptable risk in hospitals serving immunocompromised patients.

    2016-12-01

    Domestic hot water (DHW) heating is the second largest energy end use in U.S. buildings, exceeded only by space conditioning. Recirculation systems consisting of a pump and piping loop(s) are commonly used in multifamily buildings to reduce wait time for hot water at faucets; however, constant pumping increases energy consumption by exposing supply and return line piping to continuous heat loss, even during periods when there is no demand for hot water. In this study, ARIES installed and tested two types of recirculation controls in a pair of buildings in order to evaluate their energy savings potential. Demand control, temperature modulation controls, and the simultaneous operation of both were compared to the baseline case of constant recirculation. Additionally, interactive effects between DHW control fuel reductions and space conditioning (heating and cooling) were estimated in order to make more realistic predictions of the payback and financial viability of retrofitting DHW systems with these controls. Results showed that DHW fuel consumption reduced by 7 percent after implementing the demand control technique, 2 percent after implementing temperature modulation, and 15 percent after implementing demand control and temperature modulation techniques simultaneously; recirculation pump runtime was reduced to 14 minutes or less per day. With space heating and cooling interactions included, the estimated annual cost savings were 8 percent, 1 percent, and 14 percent for the respective control techniques. Possible complications in the installation, commissioning and operation of the controls were identified and solutions offered.

    The ad hoc management of natural environmental features and inappropriate social interventions could cause vulnerability of thriving urban ecosystems. For instance sub-aerial exposure, water-related hazards, urban intrinsic sensitivity, urban adaptation ability or flexibility and urban transformability factors could contribute a potential danger. In spite of seasonal climatic changes, the exposure indicates a significant geographical determinism whereas the other factors express its antithesis. The present paper aims to adapt a vulnerability-resilience indicators' multicriteria analysis to show the variability and contribution rate with regard to local water-related risks. The municipality of al-Harrash from Algiers has been selected as a case study. The urban vulnerability-resilience closely tied up with a sum of relevant indicators confirmed by the diagnosis items, which are relevant to the local urban and hydro systems. The cumulative sums are obtained from a classification process referring to several criteria implied in the water-related risks. These were formulated here for the purpose of a multicriteria analysis with the objective of assessing the urban vulnerability-resilience index and subsequently orientating the preventive strategy towards different levels of sustainable measures. With this respect the exposure and sensitivity received a significant score while adaptation ability and transformability scored very low.

    The multi-dimensional relationships that Indigenous peoples have with water are only recently gaining recognition in water policy and management activities. Although Australian water policy stipulates that the native title interests of Indigenous peoples and their social, cultural and spiritual objectives be included in water plans, improved rates of Indigenous access to water have been slow to eventuate, particularly in those regions where the water resource is fully developed or allocated. Experimentation in techniques and approaches to both identify and determine Indigenous water requirements will be needed if environmental assessment processes and water sharing plans are to explicitly account for Indigenous water values. Drawing on two multidisciplinary case studies conducted in Australia's Murray-Darling Basin, we engage Indigenous communities to (i) understand their values and explore the application of methods to derive water requirements to meet those values; (ii) assess the impact of alternative water planning scenarios designed to address over-allocation to irrigation; and (iii) define additional volumes of water and potential works needed to meet identified Indigenous requirements. We provide a framework where Indigenous values can be identified and certain water needs quantified and advance a methodology to integrate Indigenous social, cultural and environmental objectives into environmental flow assessments.

    Access to adequate quantities of water has a protective effect on human health and well-being. Despite this, public health research and interventions are frequently focused solely on water quality, and international standards for domestic water supply minimums are often overlooked or unspecified. This trend is evident in Inuit and other Arctic communities even though numerous transmissible diseases and bacterium infections associated with inadequate domestic water quantities are prevalent. Our objective was to explore the pathways by which the trucked water distribution systems being used in remote northern communities are impacting health at the household level, with consideration given to the underlying social and environmental determinants shaping health in the region. Using a qualitative case study design, we conducted 37 interviews (28 residents, 9 key informants) and a review of government water documents to investigate water usage practices and perspectives. These data were thematically analysed to understand potential health risks in Arctic communities and households. Each resident receives an average of 110 litres of municipal water per day. Fifteen of 28 households reported experiencing water shortages at least once per month. Of those 15, most were larger households (5 people or more) with standard sized water storage tanks. Water shortages and service interruptions limit the ability of some households to adhere to public health advice. The households most resilient, or able to cope with domestic water supply shortages, were those capable of retrieving their own drinking water directly from lake and river sources. Residents with extended family and neighbours, whom they can rely on during shortages, were also less vulnerable to municipal water delays. The relatively low in-home water quantities observed in Coral Harbour, Nunavut, appear adequate for some families. Those living in overcrowded households, however, are accessing water in quantities more

    Climate change is making water supply less predictable, even unreliable, in parts of the world. Urban water providers, especially in already arid areas, will need to diversify their water resources by switching to alternative sources and negotiating trading agreements to create more resilient and interdependent networks. The increasing complexity of these networks will likely require more operational electricity. The ability to document, visualize, and analyze water–energy relationships will be critical to future water planning, especially as data needed to conduct the analyses become increasingly available. We have developed a network model and decision-support tool, WESTNet, to perform these tasks. Herein, WESTNet was used to analyze a model of California’s 2010 urban water network as well as the projected system for 2020 and 2030. Results for California’s ten hydrologic regions show that the average number of water sources per utility and total electricity consumption for supplying water will increase in spite of decreasing per-capita water consumption. Electricity intensity (kWh m‑3) will increase in arid regions of the state due to shifts to alternative water sources such as indirect potable water reuse, desalination, and water transfers. In wetter, typically less populated, regions, reduced water demand for electricity-intensive supplies will decrease the electricity intensity of the water supply mix, though total electricity consumption will increase due to urban population growth. The results of this study provide a baseline for comparing current and potential innovations to California’s water system. The WESTNet tool can be applied to diverse water systems in any geographic region at a variety of scales to evaluate an array of network-dependent water–energy parameters.

    The paper proposes fuzzy logic model that deals with the physico-chemical water analysis of ground water of Chikhli town for determination of Water Quality Index (WQI). The study was carried by collection of ground water samples from about eleven hand pumps located in this town. Ground water quality is studied by systematic collection and analysis of samples. The fuzzy logic is used for the deciding the water quality index on the basis of which, water quality rankings are given to determine the quality of water. The Water Quality Index presented here is a unitless number ranging from 1 to 10. A higher number is indicative of better water quality. Around 81% of samples were found suitable for drinking purpose. It is also observed that all the parameters fall within the permissible limits laid by WHO, ISI, and ICMR, except Total Hardness, Calcium and Magnesium. The quality parameters were compared with standards laid by the World Health Organization (WHO), Indian Standards Institute (ISI) and Indian Council of Medical Research (ICMR) for drinking water quality.

    Full Text Available The rapid development of China’s textile industry has led to consumption and pollution of large volumes of water. Therefore, the textile industry has been the focus of water conservation and waste reduction in China’s 13th Five-Year Plan (2016–2020. The premise of sustainable development is to achieve decoupling of economic growth from water consumption and wastewater discharge. In this work, changes in the blue water footprint, grey water footprint, and the total water footprint of the textile industry from 2001 to 2014 were calculated. The relationship between water footprint and economic growth was then examined using the Tapio decoupling model. Furthermore, factors influencing water footprint were determined through logarithmic mean Divisia index (LMDI method. Results show that the water footprint of China’s textile industry has strongly decoupled for five years (2003, 2006, 2008, 2011, and 2013 and weakly decoupled for four years (2005, 2007, 2009, and 2010. A decoupling trend occurred during 2001–2014, but a steady stage of decoupling had not been achieved yet. Based on the decomposition analysis, the total water footprint mainly increased along with the production scale. On the contrary, technical level is the most important factor in inhibiting the water footprint. In addition, the effect of industrial structure adjustment is relatively weak.

    We evaluated damage to commercial crops caused by the monk parakeet, Myiopsitta monachus, in the Baix Llobregat agricultural area (1,024 ha) bordering the city of Barcelona, Spain. Average crop loss was 0.4% for tomatoes, 28% for corn, 9% for red plums, 36% for round plums, 37% for pears, 17% for persimmons, and 7% for quinces. Our data show that the potential damage to crops by monk parakeets in this invaded area is now a reality. As a wait–and–see approach is likely to be a more costly strategy in the long–term, policy makers should assess issues such as the extent of damage, feasibility/cost benefit analysis, and public opinion so as to avoid greater damage and loss in the future.

    Full Text Available The aim of this paper is to explore the way in which the increase of immigrants arriving in Catalonia has changed the religious map of the region, with specific attention to the city of Barcelona. This paper will discuss the transformations that have taken place in the last 15 years and analyse not just thegrowth of Islam, but other faiths as well. One of the most relevant changes has been the steady increase in the number of places ofworship for non-Catholic religious minorities. This increase is aresult of the appearance of new religions, and the expansion ofpre-existing religions. These changes include the incorporation of new languages and traditions, the provision of new services to meet the specific needs of immigrant populations and, finally, the internal transformation of the communities doctrinal profiles.

First, some antecedents are defined at the very beginnig of xxth Century, looking after to the big transformation of the sixties, the real and late Spanish bourgeois revolution. The next period corresponds to the changes started in 1986, with the integration of Spanish economy into the European Market. An evaluation of the present situation remarks the relevance of the legal constraints and of the relative delay in the development of some modern commercial forms in the City. From the study of some relevants questions on the consumers behaviour a clear conclusion appears relative to the inercia of some local trends in front of the weight of globalization.

Of 891 survivors (72 years or older), 561 (62.9%) oral examinations were completed according to the DMF Index (Decayed, Missing and Filled teeth). 42% of participants were edentate. The individuals of social class IV-V were more likely to be edentate, and to have fewer than 15 teeth compared to those in social class I-II. The DMF Index in dentate individuals (Adjusted mean=16.4) also showed significantly worse dental health for lower social classes (p = 0.001). The results of this study indicate a different level of utilization of dental health services and dental health by social class in home-dwelling seniors. Further research is needed to understand the barriers of access and social inequality.

    Full Text Available El Casc Antic de Barcelona va patir de sobrepoblació, congestió i diversos brots epidèmics fets que van augmentar la vigilància i preocupació per la higiene urbana. Un dels primers intents va començar quan Carles III i Carles IV van emetre reials decrets relatius a l'exhumació dels cementiris. El primer va prohibir de l'enterrament al costat de esglésies i hospitals i va imposar la conversió dels existents en places públiques, i el segon va permetre la construcció de cementiris extramurs lluny de les zones poblades. Això va donar pas a molts dels espais oberts de Barcelona i places de petita escala. La segona ocasió de crear espais públics deriva dels processo de desamortització de béns eclesiàstics, com la Llei d'Álvarez Mendizábal (1834-1837, i la crema de convents de 1835, quan l'Església catòlica va perdre gran part de seus convents, esglésies i col·legis reconvertits en nous edificis, carrers i places. Al segle XIX, Espanya també va ser testimoni d'un moviment higienista i diversos metges i científics van ser prominents incloent Pere Felip Monlau que va discutir a fons la higiene en tots els seus aspectes. Espanya, i Barcelona en particular, van experimentar grans onades d'immigració procedents de les zones rurals a la recerca de treball, i un creixement industrial massiu. A la dècada de 1850 es va convertir en un nucli antic superpoblat, cada vegada més dens , poc saludable i degradat, cau d’una tensió política i social inestable. Bàsicament, el casc antic era sufocant dins de les seves pròpies muralles. Monlau, igual que Cerdà després d'ell, ens descriu en els seus escrits les dràstiques condicions de vida, els espais ocupats i edificis molt alts, la manca d'infraestructura sanitària, aigua potable, llum solar i ventilació. Posa l’èmfasi en la importància de crear espais oberts, places i jardins i el seu impacte en la millora de la higiene urbana. Va cridar a la demolició de la muralla del nucli

  16. Measuring the embodied energy in drinking water supply systems: a case study in the Great Lakes region.

    A sustainable supply of both energy and water is critical to long-term national security, effective climate policy, natural resource sustainability, and social wellbeing. These two critical resources are inextricably and reciprocally linked; the production of energy requires large volumes of water, while the treatment and distribution of water is also significantly dependent upon energy. In this paper, a hybrid analysis approach is proposed to estimate embodied energy and to perform a structural path analysis of drinking water supply systems. The applicability of this approach is then tested through a case study of a large municipal water utility (city of Kalamazoo) in the Great Lakes region to provide insights on the issues of water-energy pricing and carbon footprints. Kalamazoo drinking water requires approximately 9.2 MJ/m(3) of energy to produce, 30% of which is associated with indirect inputs such as system construction and treatment chemicals.

    This report summarizes a preliminary study aimed at estimating the potential of saving potable water, (and the electrical energy used to heat it), that is presently lost directly to the drain while occupants wait for hot water to arrive at the faucet (point of use). Data were collected from five single-family homes in Palo Alto, California. Despite the small sample size in this study, the results make a compelling case for retrofitting homes with hot water recirculation systems to eliminate unnecessary wastage of water at the point of use. Technical as well as behavioral and attitudinal changes towards water conservation are necessary for a fulfilling and successful conservation effort. This report focuses on the technical issues, but behavioral issues are also noted, which may be factored into future studies involving local and state governments and utility companies.

    Full Text Available Due to the geographical location of Oman in an arid zone, agricultural production depends fully on irrigation. The traditional irrigation systems (Aflaj, sing. falaj supply more than one third of water for agriculture. Falaj is defined in the context of this paper as a canal system which provides water for domestic and agricultural uses. Oman has 3,107 active Aflaj producing about 680 Mm3 of water per year. The main objective of this study was to estimate the irrigation performance of Aflaj in Oman. Falaj al-Dariz and al-Nujaid were chosen as case studies. Both Aflaj are located in an extremely arid environment, where the rainfall is low and evapotranspiration is high. The study utilized an approach to estimate the irrigation performance of Aflaj by considering the falaj as a single unit of irrigation. The irrigation demand/supply ratio (D/S was used in the analysis as a tool of evaluation. Date palm, the dominant crop irrigated by Aflaj, was selected for the analysis. In falaj al-Dariz the date palms were slightly under irrigated on a yearly basis. On a monthly basis, in winter, the D/S was below 0.6 and in summer it was above 1.0. On the other hand, falaj al-Nujaid was supplying too much water than the date palms needed all round the year. In winter the D/S ratio was as low as 0.25. Even in summer, the D/S ratio did not much exceed 1.0.

    Breakfast is considered the most important meal of the day in an equilibrated diet. Skipping breakfast has been associated with overweight. This study aimed to describe overweight and obesity among high school students in Barcelona and to analyze their association with eating habits and sedentary behaviors. A cross-sectional study was performed in 2008 on a representative sample of high-school students in Barcelona (Spain). Overweight and obesity were defined using Body Mass Index (BMI), which was calculated from objective measurements. The prevalences of overweight and obesity were determined, and their association with eating habits, sedentary behaviors, and physical activity was analyzed using logistic regression models. A total of 3,089 students were analyzed (52% girls). The prevalence of overweight was 26.1% in boys (6.2% obese) and 20.6% in girls (3.7% obese). In both sexes, overweight was associated with being younger, having breakfast less often, being on a diet, and with a lower frequency of unhealthy food intake. Being on a diet and a lower unhealthy food intake were related to obesity in both sexes. Among boys, obesity was also associated with sedentary behaviors. The results show that overweight and obesity are a serious public health problem and confirm the importance of breakfast to prevent overweight. Moreover, these results allow us to expand our knowledge on the factors associated with overweight and obesity in order to improve current school preventive programs.

    To quantify the concentration of respirable particles equal to or smaller than 2.5μm (PM(2.5)) as a marker of second-hand smoke (SHS) exposure in a sample of hospitality venues in Barcelona 2 years after the Spanish smoking law came into effect. We performed a cross-sectional descriptive study from October to December 2007. The study population consisted of 40 hospitality venues in Barcelona selected by a random route sampling, with representation of the different types of smoking regulation included in the law (smoking allowed, smoking ban and venues with smoking areas). SHS levels were quantified by measuring PM(2.5) concentrations, which were measured using a laser photometer (Side Pack AM 510 Personal Aerosol Monitor). The measurements were carried out for 5 minutes outside the venue and for 30 minutes inside the venue. In addition, observational variables related to the characteristics of the venue and signs of tobacco consumption were recorded. The concentration of PM(2.5) in venues where smoking was still allowed was five times higher than that in venues where smoking was banned (182μg/m(3) and 34μg/m(3), respectively) and exceeded the concentration established by the US Environmental Protection Agency (EPA) as harmful (35μg/m(3)). However, in venues where smoking was banned, the concentration was lower than the EPA standard and there were no significant differences with the outdoor PM(2.5) concentration. Two years after the introduction of the Spanish smoking law, SHS exposure in venues where smoking was allowed was q still very high, representing a significant health risk for hospitality workers.

    Smoking is a preventable cause of early death and the habit starts in adolescence. The aim of this study was to describe tobacco consumption in secondary school students in 2008 and trends in the last 20 years in Barcelona. We analyzed the trend in tobacco consumption by comparing data from 8 surveys carried out between 1987 and 2008 in the 8th (2nd year of Compulsory Secondary Education), 10th (4th year of Compulsory Secondary Education) and 12th (2nd year of Compulsory Secondary Education) years of secondary school. The FRESC questionnaire was used. Data on regular and daily consumption and associated factors in 2008 were gathered and compared with those corresponding to the previous studies. Percentages of annual change were calculated with Joinpoint regression and data were stratified by sex and year of education. In 2008, 6.1% of boys and 4.5% of girls in the 8th year, 15.8% and 20.4% of those in the 10th year, respectively, and 26.1% and 33.1% of those in the 12th year, respectively, were regular smokers. A strong association was noted between regular smoking and cannabis consumption in three school years, as well as with having friends who were smokers and poor school performance. At 15-16 years old, the average annual decrease from 1996 to 2008 was 6.8% in girls and 6.1% in boys. Adolescent smoking has been decreasing in the last few years in Barcelona. There is a strong association between tobacco use and cannabis consumption. Copyright © 2013 SESPAS. Published by Elsevier Espana. All rights reserved.

    To estimate the prevalence of moderate and vigorous physical activity (MVPA), as defined by the World Health Organisation (WHO), and associated factors among teenagers from Barcelona in 2012. Cross-sectional survey to assess risk factors in a representative sample of secondary school students (aged 13-16 years, International Standard Classification of Education [ISCED] 2, n=2,162; and 17-18 years, ISCED 3, n=1016) in Barcelona. We estimated MVPA prevalence overall, and for each independent variable and each gender. Poisson regression models with robust variance were fit to examine the factors associated with high-level MVPA, and obtained prevalence ratios (PR) and 95% confidence intervals (95%CI). Only 13% of ISCED 2 and 10% of ISCED 3 students met the WHO physical activity recommendations. This percentage was lower among girls at both academic levels. MVPA was lower among ISCED 3 compared to ISCED 2 students, and among students with a lower socioeconomic status. Physical activity was associated with positive self-perception of the health status (e.g., positive self-perception of health status among ISCED 2 compared to ISCED 3 students: PR=1.31 [95%CI: 1.22-1.41] and 1.61 [95%CI: 1.44-1.81] for boys and girls, respectively]. The percentage of teenagers who met WHO MVPA recommendations was low. Strategies are needed to increase MVPA levels, particularly in older girls, and students from low socioeconomic backgrounds.

    The aim of this paper was to outline a proposed a new brackish water greenhouse desalination unit powered by geothermal energy for the development of arid and relatively cold regions, using Algeria as a case study. Countries which have abundant sea/brackish water resources and good geothermal conditions are ideal candidates for producing fresh water from sea/brackish water. The establishment of human habitats in these arid areas strongly depends on availability of fresh water. The main advantage of using geothermal energy to power brackish water greenhouse desalination units is that this renewable energy source can provide power 24 h a day. This resource is generally invariant with less intermittence problems compared to other renewable resources such as solar or wind energy. Geothermal resources can both be used to heat the greenhouses and to provide fresh water needed for irrigation of the crops cultivated inside the greenhouses. A review of the geothermal potential in the case study country is also outlined. (author)

    We studied the association between drinking water, agriculture and sporadic human campylobacteriosis in one region of British Columbia (BC), Canada. We compared 2992 cases of campylobacteriosis to 4816 cases of other reportable enteric diseases in 2005-2009 using multivariate regression. Cases were geocoded and assigned drinking water source, rural/urban environment and socioeconomic status (SES) according to the location of their residence using geographical information systems analysis methods. The odds of campylobacteriosis compared to enteric disease controls were higher for individuals serviced by private wells than municipal surface water systems (odds ratio 1·4, 95% confidence interval 1·1-1·8). In rural settings, the odds of campylobacteriosis were higher in November (P = 0·014). The odds of campylobacteriosis were higher in individuals aged ⩾15 years, especially in those with higher SES. In this region of BC, campylobacteriosis risk, compared to other enteric diseases, seems to be mediated by vulnerable drinking water sources and rural factors. Consideration should be given to further support well-water users and to further study the microbiological impact of agriculture on water.

The activities of those opposition groups, and the clandestine revolutionary Committee existing from 1861, are studied through the analysis of A. feliu Codina's memoirs. The outbreak of the revolution in Barcelona, where the committees were mainly neither republicans nor federalists, enhanced the diffusion of the federal republicanism and transformed an initial pronunciamiento into a true democratic revolution, Barcelona becoming the pioneer of the Spanish federal republicanism.

  12. Water and Land Footprints and Economic Productivity as Factors in Local Crop Choice: The Case of Silk in Malawi

    Directory of Open Access Journals (Sweden)

    Rick J. Hogeboom

    2017-10-01

    Full Text Available In deciding what crops to grow, farmers will look at, among other things, the economically most productive use of the water and land resources that they have access to. However, optimizing water and land use at the farm level may result in total water and land footprints at the catchment level that are in conflict with sustainable resource use. This study explores how data on water and land footprints, and on economic water and land productivity can inform micro-level decision making of crop choice, in the macro-level context of sustainable resource use. For a proposed sericulture project in Malawi, we calculated water and land footprints of silk along its production chain, and economic water and land productivities. We compared these to current cropping practices, and addressed the implications of water consumption at the catchment scale. We found that farmers may prefer irrigated silk production over currently grown rain-fed staple crops, because its economic water and land productivity is higher than that for currently grown crops. However, because the water footprint of irrigated silk is higher, sericulture will increase the pressure on local water resources. Since water consumption in the catchment generally does not exceed the maximum sustainable footprint, sericulture is a viable alternative crop for farmers in the case study area, as long as silk production remains small-scale (~3% of the area at most and does not depress local food markets.

    Audobon v. Superior Court is a ''watershed'' case in its integration of the public trust doctrine within traditional water law. The public trust doctrine requires the state to exercise a duty of continued supervision over the taking and use of appropriated water. As a result, the state must periodically balance the economic interests served by the water appropriations with the ecological and recreational interests protected under the public trust. The state can best meet this burden by adopting a balancing procedure that includes comprehensive, long-term planning of the economic effects and ecological interests in water appropriation. 78 references.

    Wetlands can be both a blessing and a curse. They are beneficial sources of safe water and nutrition and places from which humans derive their livelihoods. At the same time, wetlands are known to be sources of disease-causing microorganisms and invertebrates that can threaten human health. Safe water, sanitation and personal hygiene (WASH) are crucial preconditions for the prevention of disease transmission. And of special importance for people living in wetlands, depending on and being exposed to them. WASH should be prioritized especially in those wetlands that are subject to intensive use, that have a poor sanitation infrastructure, and which at the same time only provide limited water resources. However, despite this critical importance, WASH in wetlands is not well characterized in literature. This study therefore aimed at providing insights into the water, sanitation and hygiene conditions and behavioural determinants of households in wetlands by presenting the case of a rural wetland in East Africa. The mixed method approach included a broad set of empirical data collected during a household survey (n=400), an observational WASH assessment (n=397) and in-depth interviews (n=20) conducted from January to March 2015 in Ewaso Narok Swamp in Kenya. Different user groups of the wetland were targeted. The study in Ewaso Narok Swamp showed that wetland users' water supply and storage, sanitation and personal hygiene conditions were inadequate for large parts of the community and significantly differed between groups. Whereas the WASH conditions of people working in the service sector were rather positive, for pastoralists, they were correspondingly negative. The WASH behaviour was also perceived to be inadequate influenced by a variety of determining factors. The observational index as applied in this study indicated to be a valuable, rapid and efficient tool for assessing domestic WASH and for detecting differences between different groups in wetlands.

    Make-up water used for a district heating system in Beijing is about 63 kg/m(2).a, so the total quantity of make-up water is over 10 million m(3) per year. Water deficiency is very serious in Beijing. Using reclaimed water as make-up water is one of the important measures to relieve water crises of the city. This study is mainly on nanofiltration (NF) process. The reclaimed water for the experiment is the effluent of The Sixth Water Plant, an urban reclaimed water plant in Beijing. Micro-filter (MF) and activated carbon filtration are used as pretreatment units to eliminate turbidity, organic matter in reclaimed water to avoid contamination and scale on the surface of NF membrane. Four SAEHAN NE-90 membrane elements with an array of 2-1-1 are selected for the NF unit and the flow rate is controlled around 1 m(3)/h. Through the test, it has been verified that NF membrane has high removal rate to the salt and impurity of reclaimed water. The average salt removal rate of the system is more than 94%, while the rejections of bivalent ions are more than 98%. The removal rates of organic matter, NH(3)-N and TP are 77%, 96% and 84% respectively. Temperature is a main influence of the process. When temperature is increasing, the permeate flux is increasing as well. The operating pressure is an important factor effecting membrane flux also. By the data comparison it is confirmed that the appropriate operating pressure and the water recovery of NF system are 0.75 MPa and 63.5% respectively.

  17. Influence of gravity on the collective molecular dynamics of liquid water: the case of the floating water bridge

    Quantum electrodynamics (QED) produces a picture of liquid water as a mixture of a low density coherent phase and an high density non-coherent phase. Consequently, the Archimedes principle prescribes that, within a gravitational field, liquid water should be made up, at surface, mainly of the coherent fraction, which becomes a cage where the gas-like non-coherent fraction is trapped, acquiring a non-vanishing pressure (vapor tension). Therefore, it is possible to probe the QED picture by observing the behavior of liquid water under reduced gravity conditions. The floating water bridge could be a useful test model.

    Our objective was to evaluate changes in water quality parameters during 1983-2007 in a subtropical drinking water reservoir (area: 7 km(2)) located in Lake Manatee Watershed (area: 338 km(2)) in Florida, USA. Most water quality parameters (color, turbidity, Secchi depth, pH, EC, dissolved oxygen, total alkalinity, cations, anions, and lead) were below the Florida potable water standards. Concentrations of copper exceeded the potable water standard of water quality threshold of 20 μg l(-1). Concentrations of total N showed significant increase from 1983 to 1994 and a decrease from 1997 to 2007. Total P showed significant increase during 1983-2007. Mean concentrations of total N (n = 215; 1.24 mg l(-1)) were lower, and total P (n = 286; 0.26 mg l(-1)) was much higher than the EPA numeric criteria of 1.27 mg total N l(-1) and 0.05 mg total P l(-1) for Florida's colored lakes, respectively. Seasonal trends were observed for many water quality parameters where concentrations were typically elevated during wet months (June-September). Results suggest that reducing transport of organic N may be one potential option to protect water quality in this drinking water reservoir.

    Full Text Available Objectives: To estimate the health and economic benefits that would result from two scenarios of improved air quality in 57 municipalities of the metropolitan area of Barcelona. Methods: We used attributable fractions and life tables to quantify the benefits for selected health outcomes, based on published concentration-response functions and economic unit values. The mean weighted concentration of PM10 for the study population was estimated through concentration surface maps developed by the local government. Results: The annual mean health benefits of reducing the mean PM10 exposure estimated for the population in the study area (50µg/m³ to the annual mean value recommended by the World Health Organization (20µg/m³ were estimated to be 3,500 fewer deaths (representing an average increase in life expectancy of 14 months, 1,800 fewer hospitalizations for cardio-respiratory diseases, 5,100 fewer cases of chronic bronchitis among adults, 31,100 fewer cases of acute bronchitis among children, and 54,000 fewer asthma attacks among children and adults. The mean total monetary benefits were estimated to be 6,400 million euros per year. Reducing PM10 to comply with the current European Union regulatory annual mean level (40µg/m³ would yield approximately one third of these benefits. Conclusions: This study shows that reducing air pollution in the metropolitan area of Barcelona would result in substantial health and economic benefits. The benefits are probably underestimated due to the assumptions made in this study. Assessment of the health impact of local air pollution is a useful tool in public health.Objetivos: Se presenta una estimación de los beneficios para la salud y económicos de dos escenarios de mejora de la calidad del aire ambiental en 57 municipios del área metropolitana de Barcelona.

    Challenges of water and wastewater management in Alaska include the potential need for above-grade and freeze-protected piping, high unit energy costs and, in many rural areas, low population density and median annual income. However, recently developed net-zero water (NZW), i.e., nearly closed-loop, direct potable water reuse systems, can retain the thermal energy in municipal wastewater, producing warm treated potable water without the need for substantial water re-heating, heat pumping or transfer, or additional energy conversion. Consequently, these systems are projected to be capable of saving more energy than they use in water treatment and conveyance, in the temperate USA. In this paper, NZW technology is reviewed in terms of potential applicability in Alaska by performing a hypothetical case study for the city of Fairbanks, Alaska. Results of this paper study indicate that in municipalities of Alaska with local engineering and road access, the use of NZW systems may provide an energy-efficient water service option. In particular, case study modeling suggests hot water energy savings are equivalent to five times the energy used for treatment, much greater savings than in mid-latitudes, due largely to the substantially higher energy needed for heating water from a conventional treatment system and lack of need for freeze-protected piping. Further study of the applicability of NZW technology in cold regions, with expanded evaluation in terms of system-wide lifecycle cost, is recommended.

  1. The role of water vendors in water service delivery in developing countries: a case of Dala local government, Kano, Nigeria

    2017-06-01

    In Nigeria, more than 60 million people are required to meet Millennium Development Goals (MDGs) target for improved water by 2015 and is unlikely to be achieved only by public supply. To cover these water availability gaps water vendors exist and ignoring their role is potentially deceptive. The aim of this paper is to assess the role of water vendors in meeting these peoples' need and elicit household's willingness-to-pay for improved supply. The research includes cross-sectional mixed method in which questionnaire survey was performed to 218 households; and interviews and focus group discussion were conducted with water vendors. Findings reveal that water vendors supplied most households irrespective of season. Retail vendors buy 25 l at ₦4.00 (0.013) from wholesale vendors and resale at ₦20.08 (0.07) during dry and at ₦14.02 (0.05) in wet season. The price is 28 and 40 times the cost of in-house connection from Kano State Water Board (KNSWB) during rainy and dry season, respectively. Vendors who buy from hand-dug wells pay ₦100.00 (0.33) per day and draw as much water within that day. Furthermore, willingness-to-pay for in-house connection was elicited as ₦367.00 (1.20), lower than monthly flat fixed tariff set by KNSWB. The study recommends recognizing vendors formally in form of public private partnership so that technical and financial support be given, thus their activities and charges be regulated. People's perception on water should be changed through education and enlightening. Further research should focus on estimating total volume of water supplied by water vendors.

    Full Text Available The complexity of explaining highly scientific information and juggling a plethora of social values is leading agencies and communities such as those in the Palouse Basin to explore the use of participatory modeling processes using system dynamics. Participatory system dynamics as a methodology creates a transparent nexus of science, policy options, social concerns and local knowledge that enhances discussion of issues surrounding the use of natural resources. The process of developing a systems model uses the tenets of scientific theory, hypothesis testing and clear statements of assumptions. A unique aspect of the Palouse basin project is the use of system dynamics to describe ground water dynamics in a sole source confined aquifer system. There are, as of yet, no standards for analyzing participatory modeling projects, therefore, we use case study analysis to describe the process, insights and qualitative measurements of success.

    Full Text Available Case study of corrosion failure of urban water supply system caused by the harmful effects of stray currents was presented. The failure occurred at a site distant from the sources of these currents namely the tramway and railway traction systems. Diagnosis revealed the stray currents flow to pipeline over a remote distance of 800/1000 m from the point of failure. At the point of failure stray currents flowed from the pipeline to the ground through external insulation defects, causing the process of electrolytic corrosion of the metal. Long distance between the affected section of the pipeline and the sources of stray currents excludes the typical protection against stray currents in the form of electrical polarized drainage. Corrosion protection at this point can be achieved by using the earthing electrodes made of magnesium, which will also provide cathodic current protection as galvanic anode.

    Household water treatment (HWT) can improve drinking water quality and prevent disease, if used correctly and consistently. While international monitoring suggests that 1.8 billion people practice HWT, these estimates are based on household surveys that may overstate the level of consistent use and do not address microbiological effectiveness. We sought to examine how HWT is practiced among households identified as HWT users according to international monitoring standards. Case studies were conducted in urban and rural Zambia. After a baseline survey (urban: 203 households, rural: 276 households) to identify HWT users, 95 urban and 82 rural households were followed up for 6 weeks. Consistency of HWT reporting was low; only 72.6% of urban and 50.0% of rural households reported to be HWT users in the subsequent visit. Similarly, availability of treated water was low, only 23.3% and 4.2% of urban and rural households, respectively, had treated water on all visits. Drinking water was significantly worse than source water in both settings. Only 19.6% of urban and 2.4% of rural households had drinking water free of thermotolerant coliforms on all visits. Our findings raise questions about the value of the data gathered through the international monitoring of HWT practices as predictors of water quality in the home. PMID:26572868

  5. Usefulness of satellite water vapour imagery in forecasting strong convection: A flash-flood case study

    Georgiev, Christo G.; Kozinarova, Gergana

    Using a case study of a severe convective event as an example, a framework for interpreting 6.2 µm channel satellite imagery that enables to indicate upper-level conditioning of the convective environment is presented and discussed. In order to illustrate the approach, all convective cells during the summer of 2007 that produced precipitations over Bulgaria are considered. They are classified regarding the observed moisture pattern in mid-upper levels as well as the low-level conditions of air humidity and convergence of the flow. Water vapour (WV) images are used to study the evolution of the upper-level moist and dry structures. The proposed interpretation is that the role of the upper-level dry boundaries identified in the WV imagery as favoured areas for the initiation of deep moist convection cannot be understood (and hence cannot be forecasted accurately) by considering them in isolation from the dynamic rate at which they are maintained. The paper examines the 23 June 2006 flash flood in Sofia city as a case, in which the operational forecast of the National Institute of Meteorology and Hydrology of Bulgaria based on the mesoscale NWP model ALADIN underestimated the severity of the convective process. A comparison between the satellite water vapour imagery and the corresponding geopotential field of the dynamical tropopause, expressed in terms of potential vorticity (PV), shows an error in the performance of the ARPEGE operational numerical model. There is an obvious mismatch between the PV anomaly structure and the dry zone of the imagery. The forecast field shows underestimation of the tropopause height gradient and displacement of the PV anomaly to the southwest of the real position seen in the satellite image. It is concluded that the observed poor forecast is a result of the ARPEGE failure to treat correctly the interaction between the PV anomaly and the low-level warm anomaly.

  6. Exploiting Policy Obscurity for Legalising Water Grabbing in the Era of Economic Reform: The Case of Maharashtra, India

    2012-06-01

    Full Text Available Since the last two decades, economic reform in India is exerting pressure on limited land and water resources. This article argues that sectoral reforms underway in different areas such as water, electricity, and the export sector are giving rise to a new form of water grabbing in the state of Maharashtra, India. This water grabbing is legitimised by the use, application and redefinition of reform instruments such as the sectoral policy statements and laws. Maharashtra, like many other Indian states, has been a theatre for the play of power among different interest groups over control and access to water resources developed through state funding. Dams were built at the cost of depriving the upland riparian communities of their land, water and other resources. The water provided by the dams – which strengthened the political power of the leaders representing the irrigated plains – is now at the core of a shift in regional power equations. Based on case studies of three dams the paper presents these contemporary developments around water allocation and re-appropriation. These developments pertain to the shift from the erstwhile focus on securing water for irrigation to the new focus of securing water to facilitate international and domestic private investments. The paper concludes by arguing that the state is able to legitimise this form of water grabbing due the emergence of a new and grand political coalition and nexus that has emerged at the behest of the ongoing economic reforms.

    Full Text Available This article aims to analyze some basic criteria for a sustainable use of water in an international watershed shared by Mexico and the United States. The study area comprises the region of Ambos Nogales, which is located inside the Upper Santa Cruz River Basin. This portion of the watershed represents the main ecosystem and the main source of water for urban and rural populations located in this region. Following criteria of sustainability the authors revise and adapt to the case of Ambos Nogales, a set of guidelines proposed by the Pacific Institute for Studies in Development, Environment, and Security. These guidelines include the following elements: basic water requirements needed to maintain quality of life in the population and the health of ecosystems; water quality that meets certain minimum standards; human actions and their impact on long-term renewability of freshwater stocks and flows; collection of data concerning water resources, use and quality of water; institutional mechanisms to prevent and resolve conflicts; and a democratic process of water-planning and decision-making. These twin cities have a long history of cooperation and conflict linked to water resources, which makes available enough information to create a diagnostic about the water management inside a binational arena, and allowing to explore possibilities for a better water resources management under a sustainable regime and from an international perspective. Keywords: Sustainability, binational water management, ambos Nogales region.

    Due to the effects of climate change and the increasing demand on water, sustainable development in term of water resources management has become a major challenge. In this context, the application of simulation models is useful to duel with the uncertainty and complexity of water system by providing stakeholders with the best solution. This paper outlines an integrated management planning network is developed based on Water Evaluation and Planning (WEAP) to evaluate current and future water management system of Langat River Basin, Malaysia under various scenarios. The WEAP model is known as an integrated decision support system investigate major stresses on demand and supply in terms of water availability in catchment scale. In fact, WEAP is applicable to simulate complex systems including various sectors within a single catchment or transboundary river system. To construct the model, by taking account of the Langat catchment and the corresponding demand points, we defined the hydrological model into 10 sub-hydrological catchments and 17 demand points included the export of treated water to the major cities outside the catchment. The model is calibrated and verified by several quantitative statistics (coefficient of determination, R2; Nash-Sutcliffe efficiency, NSE and Percent bias, PBIAS). The trend of supply and demand in the catchment is evaluated under three scenarios to 2050, 1: Population growth rate, 2: Demand side management (DSM) and 3: Combination of DSM and reduce non-revenue water (NRW). Results show that by reducing NRW and proper DSM, unmet demand able to reduce significantly.

    The pollution of waters ecosystems is caused by natural and artificial factors in Tarim River. Temporal and spatial variation of surface runoff is the main reason for changes of coupling relationship between water and salt. In the end of 1950s, mineralization degree was less than 1.0 g.L-1 from the upper reaches to the lower reaches of Tetema Lake in Tarim River. At present, only in July, August and October, mineralization degree is less than 1.0 g.L-1. During the other months, mineralization degree is more than 3.0 g.L-1 in Alaer Lake. In Qiala (the lower reaches of Tarim River), mineralization degree is more than 1.0 g.L-1 except in March. Moreover, mineralization degree is about 5.0 g.L-1 in July and December. It is showed that annual water quality belongs to the fifth seriously polluted water in Alaer, Xinquman and Yingbazha. Meanwhile, annual water quality in Qiala belongs to the fourth polluted water. In a word, water quality state and hydrological chemistry component are the most obviously indicator for coupling relationship between water and salt in Tarim River.

    The process of making surface water fit to drink by means of physicochemical treatments generates an amount of sludge approximately equivalent to 5% of the total volume of the water treated. According to the legislation currently in force, in most cases this sludge should be disposed of in dedicated dumps, which implies major costs for the operator in terms of transport and dumping fees. In Spain, some 120,000 tonnes of such waste are produced every in over 200 water treatment plants. Since 1995, Aguas de barcelona has been working on designing and installing a unit at its treatment plant in Sant Joan Despi, near Barcelona, to transform this waste into a product with value added. Starting out from a conventional sludge treatment installation based on thickening and dehydration by centrifugation, it went a stage further and introduced an innovation consisting of drying the sludge by a process of atomization. This generates a ceramic powder with a humidity of between 3 and 5% that can be sold on the market for use in making quality ceramics. (Author)

    The Department of Energy’s (DOE’s) Light Water Reactor Sustainability Program aims to develop and deploy technologies that will make the existing U.S. nuclear fleet more efficient and competitive. The program has developed a standard methodology for determining the impact of new technologies in order to assist nuclear power plant (NPP) operators in building sound business cases. The Advanced Instrumentation, Information, and Control (II&C) Systems Technologies Pathway is part of the DOE’s Light Water Reactor Sustainability (LWRS) Program. It conducts targeted research and development (R&D) to address aging and reliability concerns with the legacy instrumentation and control and related information systems of the U.S. operating light water reactor (LWR) fleet. This work involves two major goals: (1) to ensure that legacy analog II&C systems are not life-limiting issues for the LWR fleet and (2) to implement digital II&C technology in a manner that enables broad innovation and business improvement in the NPP operating model. Resolving long-term operational concerns with the II&C systems contributes to the long-term sustainability of the LWR fleet, which is vital to the nation’s energy and environmental security. The II&C Pathway is conducting a series of pilot projects that enable the development and deployment of new II&C technologies in existing nuclear plants. Through the LWRS program, individual utilities and plants are able to participate in these projects or otherwise leverage the results of projects conducted at demonstration plants. Performance advantages of the new pilot project technologies are widely acknowledged, but it has proven difficult for utilities to derive business cases for justifying investment in these new capabilities. Lack of a business case is often cited by utilities as a barrier to pursuing wide-scale application of digital technologies to nuclear plant work activities. The decision to move forward with funding usually hinges on

    Full Text Available Water resources planning processes involve different kinds of decisions that are generally evaluated under a stationary climate scenario assumption. In general, the possible combinations of interventions are mutually compared as single alternatives. However, the ongoing climate change requires us to reconsider this approach. Indeed, what have to be compared are not individual alternatives, but families of alternatives, characterized by the same structural decisions, i.e. by actions that have long-term effects and entail irrevocable changes in the system. The rationale is that the structural actions, once they have been implemented, cannot be easily modified, while the management decisions can be adapted to the evolving conditions. This paper considers this methodological problem in a real case study, in which a strategic decision has to be taken: a new barrage was proposed to regulate Lake Maggiore outflow, but, alternatively, either the present barrage can be maintained with its present regulation norms or with a new one. The problem was dealt with by multi-criteria decision analysis involving many stakeholders and two decision-makers. An exhaustive set of indicators was defined in the participatory process, conducted under the integrated water resource management paradigm, and many efficient (in Pareto sense regulation policies were identified. The paper explores different formulations of a global index to evaluate and compare the effectiveness of the classes of alternatives under both stationary and changing hydrological scenarios in order to assess their adaptability to the ongoing climate change.

    Sustainability assessments provide scientific support in decision procedures towards sustainable solutions. However, in order to contribute in identifying and choosing sustainable solutions, the sustainability assessment has to fit the decision context. Two complicating factors exist. First, different stakeholders tend to have different views on what a sustainability assessment should encompass. Second, a plethora of sustainability assessment methods exist, due to the multi-dimensional characteristic of the concept. Different methods provide other representations of sustainability. Based on a literature review, we present a protocol to facilitate method selection together with stakeholders. The protocol guides the exploration of i) the decision context, ii) the different views of stakeholders and iii) the selection of pertinent assessment methods. In addition, we present an online tool for method selection. This tool identifies assessment methods that meet the specifications obtained with the protocol, and currently contains characteristics of 30 sustainability assessment methods. The utility of the protocol and the tool are tested in a case study on the recovery of resources from domestic waste water. In several iterations, a combination of methods was selected, followed by execution of the selected sustainability assessment methods. The assessment results can be used in the first phase of the decision procedure that leads to a strategic choice for sustainable resource recovery from waste water in the Netherlands.

    Ecological assessments of surface water bodies are essential in order to evaluate the level of degradation in freshwater ecosystems and to address the subsequent decline in services they provide. These assessments cover multiple aspects of the aquatic environment, particularly biological elements due to their ability to respond to all pressures within an ecosystem. Such assessments can enable the identification of the multiple pressures which threaten water bodies, facilitating sustainable decisions regarding their management to be identified. Here, the design requirements of the networks which facilitate ecological assessments are presented. A river basin district in England is used as a case study to investigate the number of elements monitored, the number of failing elements and the relationship between failing elements. Findings demonstrate the value of ensuring that monitoring networks are risk based and appropriately designed to meet their objectives. This therefore requires that monitoring is not only for the communicating of compliance but also for use iteratively so that the design of monitoring networks and ultimately management can be continually improved.

The paper explores different formulations of a global index to evaluate and compare the effectiveness of the classes of alternatives under both stationary and changing hydrological scenarios in order to assess their adaptability to the ongoing climate change.

  16. The Three Domains of Conservation Genetics: Case Histories from Hawaiian Waters

    Science.gov (United States)

    2016-01-01

    The scientific field of conservation biology is dominated by 3 specialties: phylogenetics, ecology, and evolution. Under this triad, phylogenetics is oriented towards the past history of biodiversity, conserving the divergent branches in the tree of life. The ecological component is rooted in the present, maintaining the contemporary life support systems for biodiversity. Evolutionary conservation (as defined here) is concerned with preserving the raw materials for generating future biodiversity. All 3 domains can be documented with genetic case histories in the waters of the Hawaiian Archipelago, an isolated chain of volcanic islands with 2 types of biodiversity: colonists, and new species that arose from colonists. This review demonstrates that 1) phylogenetic studies have identified previously unknown branches in the tree of life that are endemic to Hawaiian waters; 2) population genetic surveys define isolated marine ecosystems as management units, and 3) phylogeographic analyses illustrate the pathways of colonization that can enhance future biodiversity. Conventional molecular markers have advanced all 3 domains in conservation biology over the last 3 decades, and recent advances in genomics are especially valuable for understanding the foundations of future evolutionary diversity.

    Based on comprehensive consideration of soil environmental quality, pollution status of river, environmental vulnerability and the stress of pollution sources, a technical method was established for classification of priority area of soil environmental protection around the river-style water sources. Shunde channel as an important drinking water sources of Foshan City, Guangdong province, was studied as a case, of which the classification evaluation system was set up. In detail, several evaluation factors were selected according to the local conditions of nature, society and economy, including the pollution degree of heavy metals in soil and sediment, soil characteristics, groundwater sensitivity, vegetation coverage, the type and location of pollution sources. Data information was mainly obtained by means of field survey, sampling analysis, and remote sensing interpretation. Afterwards, Analytical Hierarchy Process (AHP) was adopted to decide the weight of each factor. The basic spatial data layers were set up respectively and overlaid based on the weighted summation assessment model in Geographical Information System (GIS), resulting in a classification map of soil environmental protection level in priority area of Shunde channel. Accordingly, the area was classified to three levels named as polluted zone, risky zone and safe zone, which respectively accounted for 6.37%, 60.90% and 32.73% of the whole study area. Polluted zone and risky zone were mainly distributed in Lecong, Longjiang and Leliu towns, with pollutants mainly resulted from the long-term development of aquaculture and the industries containing furniture, plastic constructional materials and textile and clothing. In accordance with the main pollution sources of soil, targeted and differentiated strategies were put forward. The newly established evaluation method could be referenced for the protection and sustainable utilization of soil environment around the water sources.

    Large-scale interbasin water transfer, which changes basins by creating new hydrological cycles, has the potential to affect local and regional climate. In this paper, the effects of interbasin water transfer on regional climate are studied based on numerical simulations with the regional climate model RegCM3. The Middle Route of South-to-North Water Transfer Project (MRSNWTP) in China is chosen as a case study to investigate the climatic responses under the three water transfer schemes with the intensities of 74.99, 85.31, and 118.16 billion m3/year (named Scheme 1, Scheme 2, and Scheme 3, respectively) based on the simplifications of the project programming. Four ten-year simulations are performed, which are the control run (MCTL) without water transfer, and three water transfer runs MWT1, MWT2, and MWT3 related to the Schemes 1, 2, and 3, respectively. For the three Schemes compared to the case without water transfer, we find increases of 1.47, 1.71, and 2.32 mm in top-layer soil moisture, and increases of 5.57, 6.40, and 8.99W/m2 in latent heat flux, respectively, as a directly influence for injecting water into the intake area. The increases in latent heat fluxes and those in evaporation are accompanied with the decreases of 4.30, 5.05, and 7.12W/m2 in sensible heat flux, the decreases of 0.11, 0.14, and 0.18 ° in mean air temperature, and the increases of 8.54, 7.89, and 18.2 mm in precipitation in the intake grid cells and even their adjacent ones. The intensity of climatic influences positively relates to the transferred water quantity, has strong seasonal variability, and takes a greater effect in spring and autumn than that in summer and winter. Further analysis shows that the transferred water can reduce both the seasonal temperature range and the diurnal temperature range; the temperature decreasing can diffuse over almost the whole Huabei Plain below 700 hPa, and hence weaken the wind velocity of the easterly breeze. It follows from the analyses on

    Ngwenya, B. N.; Kgathi, D. L.

    This case study investigates access to potable water in HIV/AIDS related home-based care households in five rural communities in Ngamiland, Botswana. Primary data collected from five villages consisted of two parts. The first survey collected household data on demographic and rural livelihood features and impacts of HIV/AIDS. A total of 129 households were selected using a two-stage stratified random sampling method. In the second survey, a total of 39 family primary and community care givers of continuously ill, bed-ridden or non-bed-ridden HIV/AIDS patients were interviewed. A detailed questionnaire, with closed and open-ended questions, was used to collect household data. In addition to using the questionnaire, data were also collected through participant observation, informal interviews and secondary sources. The study revealed that there are several sources of water for communities in Ngamiland such as off-plot, outdoor (communal) and on-plot outdoor and/or indoor (private) water connections, as well as other sources such as bowsed water, well-points, boreholes and open perennial/ephemeral water from river channels and pans. There was a serious problem of unreliable water supply caused by, among other things, the breakdown of diesel-powered water pumps, high frequency of HIV/AIDS related absenteeism, and the failure of timely delivery of diesel fuel. Some villages experienced chronic supply disruptions while others experienced seasonal or occasional water shortages. Strategies for coping with unreliability of water supply included economizing on water, reserve storage, buying water, and collection from river/dug wells or other alternative sources such as rain harvesting tanks in government institutions. The unreliability of water supply resulted in an increase in the use of water of poor quality and other practices of poor hygiene as well as a high opportunity cost of water collection. In such instances, bathing of patients was cut from twice daily to once or

    Full Text Available Participatory research has in recent years become a popular approach for problem-oriented scientific research that aims to tackle complex problems in a real management context. Within the European Union project NeWater, stakeholder processes were initiated in seven case studies to develop approaches for adaptive water management. The Uzbek part of the Amudarya River basin was one of the studied river basins. However, given the current political and cultural context in Uzbekistan, which provides little room for stakeholder participation, it was unclear to what extent participation could be realized there. In this paper, we present an evaluation of the participatory research carried out in the Amudarya case study with respect to (i the choice and application of different participatory methods and their adaptation to the given political, socioeconomic, and cultural environment, (ii their usefulness in improving system understanding and developing strategies and measures to improve water management and monitoring, and (iii their acceptance and suitability for enhancing policy-making processes in the Amudarya River basin context. The main lessons learned from the comparison of the different participatory methods were (1 the stakeholder process provided an opportunity for meetings and discussions among stakeholders from different organizational levels and thus promoted communication between different levels and organizations, and (2 in a context where most stakeholders are not generally involved in policy-making, there is a danger of raising expectations that a research project cannot meet, e.g., of transferring local interests to higher levels. Our experience shows that in order to choose participatory methods and adapt them to the Uzbek cultural and political setting (and most likely this applies to other post-Soviet transition countries as well, four aspects should be taken into account: the time required to prepare and apply the method, good

    In recent years, governmental institutes have started to use citizen science as a form of public participation. The Dutch water authorities are among them. They face pressure on the water governance system and a water awareness gap among the general public, and consider citizen science a possible solution. The reasons for practitioners to engage in citizen science, and in particular those of government practitioners, have seldom been studied. This article aims to pinpoint the various viewpoints of practitioners at Dutch regional water authorities on citizen science. A Q-methodological approach was used because it allows for exploration of viewpoints and statistical analysis using a small sample size. Practitioners (33) at eight different water authorities ranked 46 statements from agree to disagree. Three viewpoints were identified with a total explained variance of 67 %. Viewpoint A considers citizen science a potential solution that can serve several purposes, thereby encouraging citizen participation in data collection and analysis. Viewpoint B considers citizen science a method for additional, illustrative data. Viewpoint C views citizen science primarily as a means of education. These viewpoints show water practitioners in the Netherlands are willing to embrace citizen science at water authorities, although there is no support for higher levels of citizen engagement.

    The post-communist period (after 1989) caused important changes in the functional structure of Iasi municipality. The partly dismantling of the industrial area, the urban sprawl against the periurban and agricultural space, the new infrastructure works, all these determined important changes of soils' physical and morphological properties (e.g. porosity, density, compaction, infiltration rate etc., in the first case, and changes in soil horizons, in the second case etc.). This study aims to prove the variability of physical properties through the combination of statistical and geostatistical methods intended for a correct spatial representation. Water infiltration in urban soils was analyzed in relation to land use and the age of parental materials. Field investigations consisted in measurements of the water infiltration (by the means of Turf Tech infiltrometer), resistance to penetration (penetrologger), moisture deficit (Theta Probe) and resistivity (EC) for 70 equally distanced points (750 m x 750 m) placed in a grid covering more than 33 km2. In the laboratory, there were determined several parameters as density, porosity (air pycnometer), gravimetric moisture and other hydrophysical indicators. Filed investigations results are very heterogeneous, because of the human intervention on soils. The curves of variation for the rate water infiltration in soils indicate a downward trend, from high values in first time interval (one minute), between 5000 and 60 mm/h-1, gradually decreasing to the interval of 5-10 minutes (between 30 and 1000 mm/ h-1 to a general trend of flattening after a large time interval (in the timeframe of 50-60 minutes, the infiltration rate ranges between 4 and 142 mm•h-1). The highest frequency (≥65%) caracterizes the infiltration rates between 20 and 65 mm•h-1. For each analyzed sector (residential areas, industrial areas, degraded lands, recreational areas - parks and botanical gardens, forests heterogeneous agricultural lands), the

    We have compared the Collaborative Risk Informed Decision Analysis(CRIDA) method to traditional Integrated Water Resources Management Planning (IWRM) through a water supply case study in Central Cebu, the Philippines. In 2006 an IWRM planning process was applied to the Central Cebu region with the goal to "meet demand for safe water supply and lay the foundation in addressing the related issues of water quality and watershed protection". The stakeholder led process resulted in the selection of a final water management strategy titled, "Water for all Cebuanos". While the 2006 planning study was successful in selecting a stakeholder approved water management strategy, much advancement has since been made in decision making under uncertainty. The CRIDA approach, combining a bottom up decision scaling approach with adaptation pathways, to planning under uncertainty was applied in hindsight to the same case study. This resulted in updated recommendations for the Central Cebu water supply system. The paper shows how and why by following the CRIDA methodology we may arrive at different recommended pathways for adaptation given the set of decision criteria and the methods used for incorporating long term uncertainty in the evaluation

    What do you use water for?If someone asked you this question you would probably think right away of water for drinking. Then you would think of water for bathing, brushing teeth, flushing the toilet. Your list would get longer as you thought of water for cooking, washing the dishes, running the garbage grinder. Water for lawn watering, for play pools, for swimming pools, for washing the car and the dog. Water for washing machines and for air conditioning. You can hardly do without water for fun and pleasure—water for swimming, boating, fishing, water-skiing, and skin diving. In school or the public library, you need water to wash your hands, or to have a drink. If your home or school bursts into flames, quantities of water are needed to put it out.In fact, life to Americans is unthinkable without large supplies of fresh, clean water. If you give the matter a little thought, you will realize that people in many countries, even in our own, may suffer from disease and dirt simply because their homes are not equipped with running water. Imagine your own town if for some reason - an explosion, perhaps - water service were cut off for a week or several weeks. You would have to drive or walk to a neighboring town and bring water back in pails. Certainly if people had to carry water themselves they might not be inclined to bathe very often; washing clothes would be a real chore.Nothing can live without water. The earth is covered by water over three-fourths of its surface - water as a liquid in rivers, lakes and oceans, and water as ice and snow on the tops of high mountains and in the polar regions. Only one-quarter of our bodies is bone and muscle; the other three-fourths is made of water. We need water to live, and so do plants and animals. People and animals can live a long time without food, but without water they die in a few days. Without water, everything would die, and the world would turn into a huge desert.

This article will discuss nations, the importance of bullfighting and soccer to Iberian cultures, Catalan political parties and their role in the nationalist movement, the vote to prohibit bullfighting and FC Barcelona´s increasing political conscious. I conclude that bullfighting and soccer have been used by political parties and those associated with the nationalist movement to foster feelings of difference with Spain. These feelings have been passed from the top down to the Catalan people and risk alienating those who are not in agreement with the nationalist movement.Resumen: Este trabajo examina el papel que la corrida de toros y el equipo de fútbol FC Barcelona han hecho en el movimiento continuo hacia la independencia en Cataluña.

    To obtain a sustainable water catchment in the dune area of the Flemish west coast, the integration of treated domestic wastewater in the existing potable water production process is planned. The hygienic hazards associated with the introduction of treated domestic wastewater into the water cycle are well recognised. Therefore, the concept of HACCP (Hazard Analysis and Critical Control Points) was used to guarantee hygienically safe drinking water production. Taking into account the literature data on the removal efficiencies of the proposed advanced treatment steps with regard to enteric viruses and protozoa and after setting high quality limits based on the recent progress in quantitative risk assessment, the critical control points (CCPs) and points of attention (POAs) were identified. Based on the HACCP analysis a specific monitoring strategy was developed which focused on the control of these CCPs and POAs.

    Anthropogenic-induced water quality pollution is a major environmental problem in freshwater ecosystems today. As a result of this, eutrophication of lakes occurs. Population and economic development are key drivers of water resource pollution. To evaluate how growth in the riparian population and in the gross domestic product (GDP) with unplanned development affects the water quality of the lake, this paper evaluates Lake Victoria Kenyan waters basin. Waters quality data between 1990 and 2012 were analyzed along with reviews of published literature, papers, and reports. The nitrate-nitrogen (NO3-N), soluble phosphorus (PO4-P), chlorophyll a, and Secchi transparencies were evaluated as they are key water quality indicators. The NO3-N increased from 10 μg l(-1) in 1990 to 98 μg 1(-1) in 2008, while PO4-P increased from 4 μg l(-1) in 1990 to 57 μg l(-1) in 2008. The population and economic growth of Kenya are increasing with both having minimums in 1990 of 24.143 million people and 12.18 billion US dollars, to maximums in 2010 of 39.742 million people and 32.163 billion US dollars, respectively. A Secchi transparency is reducing with time, indicating an increasing pollution. This was confirmed by an increase in aquatic vegetation using an analysis of moderate resolution imaging spectroradiometer (MODIS) images of 2000 and 2012 of Kenyan waters. This study found that increasing population and GDP increases pollution discharge thus polluting lakes. One of major factors causing lake water pollution is the unplanned or poor waste management policy and service.

    Full Text Available The metropolitan city of Istanbul is becoming overcrowded and the demand for clean water is steeply rising in the city. The use of analytical approaches has become more and more critical for forecasting the water supply and demand balance in the long run. In this research, Istanbul’s water supply and demand data is collected for the period during 2006 and 2014. Then, using an autoregressive integrated moving average (ARIMA model, the time series water supply and demand forecasting model is constructed for the period between 2015 and 2018. Three important sustainability metrics such as water loss to supply ratio, water loss to demand ratio, and water loss to residential demand ratio are also presented. The findings show that residential water demand is responsible for nearly 80% of total water use and the consumption categories including commercial, industrial, agriculture, outdoor, and others have a lower share in total water demand. The results also show that there is a considerable water loss in the water distribution system which requires significant investments on the water supply networks. Furthermore, the forecasting results indicated that pipeline projects will be critical in the near future due to expected increases in the total water demand of Istanbul. The authors suggest that sustainable management of water can be achieved by reducing the residential water use through the use of water efficient technologies in households and reduction in water supply loss through investments on distribution infrastructure.

    South Africa is one of the largest ferrochromium (FeCr) producers. Most FeCr is exported to developed countries. Therefore the impact of this industry is of national and international importance. Cr(VI) and conductivity of surface water in four case study areas, near five FeCr smelters were monitored for approximately 1 year. Results indicated that FeCr production in three case study areas had a negative influence on the Cr(VI) concentration and/or the conductivity of surface waters. In the remaining case study areas, drinking water, originating from groundwater, was severely polluted with Cr(VI). The main factors causing pollution were surface run-off and/or seepage, while atmospheric deposition did not seem to contribute significantly. The extinction of diatoms during a severe Cr(VI) surface water pollution event (concentrations up to 216 µg/L) in one of the case study areas was also observed, which clearly indicates the ecological impact of such surface water pollution events.

The effects of interbasin water transfer on local and regional climates were then studied based on numerical simulations conducted using the RegCM3 model. The Middle Route of the South-to-North Water Transfer Project (MRSNWTP) in China was chosen as a case study to investigate the climatic responses under three different water transfer schemes with three intensities. Four 10-year simulations were conducted, a control run (MCTL) without water transfer, and three water transfer runs (MWT1, MWT2, and MWT3) related to the three schemes. In the three water transfer runs, spatial and temporal water transfer data were derived from the schemes under the assumption that the quantity of water to be transferred into a county in the intake area in a year for each scheme was distributed evenly into each time step. Increases in top-layer soil moisture and latent heat flux were observed when compared to the control, and these increases were found to occur as a direct result of injecting water into the intake area. The increases in latent heat flux and evaporation were accompanied with decreases in sensible heat flux, mean air temperature, and increases in precipitation in the intake area. These differences were generally small and statistically insignificant, indicating that the water transfer plays a small role in influencing regional climate in our simulations. However, the climatic influence intensity of a water transfer scheme was found to be positively related to the quantity of water to be transferred, and to have strong seasonal variability, with larger effect being observed in spring and autumn than in summer and winter. We also conducted a water transfer run, MWT4, using the same configuration as MWT3 but under the assumption that the quantity of water was

    Full Text Available La pequeña iglesia de Sant Valenti se halla en el término municipal de Les Cabanyes, muy cerca de Vilafranca del Penedes (Barcelona. El mal estado en que se encontraba el edificio requería una inmediata restauración, de la que se hizo cargo el Servicio de Patrimonio Arquitectónico de la Diputación de Barcelona. Siguiendo la norma de dicho Servicio, antes de la intervención arquitectónica se llevó a cabo una exhaustiva investigación histórica (dirigida por el doctor Alberto López Mullor que comprendió una excavación arqueológica, un estudio documental y un análisis artístico. A nosotros nos correspondió el estudio de las pinturas murales que cubrían buena parte del templo.
