    Metro Manila is the commercial, industrial, financial, cultural and administrative center of the Philippines, and the world's 100 largest business corporations and 60% of all manufacturing firms. Experts predict that Metro Manila will continue to experience the surging population growth rate it recorded between 1980 and 1985 of about 3.4% annually and then decline to about 2% annually by the year 2000. Metro Manila's population is primarily young, with 35% of its total population under age 15. Although poverty is widespread in Metro Manila, with about 60% of households officially below the poverty line of a paltry $120 a month for a family of 6, Metro Manila still offers most interregional in-migrants a better life. The labor force participation rate has averaged around 54% annually in recent years. As in most cities of the developing world, manufacturing employment is giving way to service - sector employment. The dire need for adequate housing in Metro Manila cannot be overstated; although government spending on housing rose from 260 million to 1.1 billion pesos between 1978 and 1983, public investment could not keep up with the pressing demands of new family formation and in-migration. The most up-to-date analysis of Metro Manila demographics is Population Growth and Policies in Mega-Cities: Metro Manila, published by the UN in 1986.

    The effects of workplace interventions on sickness absence are poorly understood, in particular in ageing workers. To analyse the effects of a senior programme on sickness absence among blue-collar food industry workers of a food company in Finland. We followed up 129 employees aged 55 years or older, who participated in a senior programme (intervention group), and 229 employees of the same age from the same company who did not participate (control group). Total sickness absence days and spells of 1-3, 4-7, 8-21 and >21 days were recorded for the members of the intervention group from the year before joining the programme and for the control group starting at age 54 years. Both groups were followed for up to 6 years. The median number of sickness absence days per person-year increased significantly from baseline in both groups during the follow-up. Compared with the control group, the intervention group had increased risk for 1-3 days spells [rate ratio 1.34 (1.21-1.48)] and 4-7 days spells [rate ratio 1.23 (1.07-1.41)], but the risk for >21 days spells was decreased [rate ratio 0.68 (0.53-0.88)] after participation in the senior programme. A programme to enhance individual work well-being in ageing workers may increase short-term but reduce long-term sickness absence.

    2016-10-01

    Full Text Available Niche dating sites have become a popular trend in the online dating industry; yet, little is known about the specialization strategies these sites use to cater to their users’ needs. Moreover, previous research alludes to the idea that many of these sites may be engaging in pseudo-individualization—a deceptive technique that creates an illusion of specialization. This study focuses on niche dating sites for older adults, one of the fastest growing niches in online dating. Through a qualitative content analysis and close reading of older-adult dating sites, I seek to determine how and to what extent online dating sites that target older adults actually customize their services to benefit this population. Three key findings emerge: (1 the use of mass segmentation, a strategy that combines elements of both mass marketing and market segmentation; (2 a strategic broadening of the boundaries of the older-adult niche; and (3 the use of deceptive advertising to attract users. These findings suggest that older-adult dating sites are, in fact, engaging in pseudo-individualization. They also highlight some of the unique aspects of online media that facilitate this practice. Implications for both online daters and site producers are discussed.

  13. An industrial perspective on the design and development of medicines for older patients.

    An increasing elderly population is leading to a change in the global demographics. This presents a new challenge to society and the pharmaceutical industry. This demographic shift is providing an opportunity for the pharmaceutical industry to meet the specific needs of the changing patient population. One issue that has been identified is defining what is meant by "an older patient", since this definition cannot be simply limited to chronological age. The fundamental purpose of the design and development process is to create a product that can be used by the patient group in a safe and efficacious manner. In the pharmaceutical industry ICH Q8 is used to guide the design and development of medicines. The process leads to the definition of the Quality Target Product Profile (QTPP) for a specific drug product and patient population. One can imagine a product with various presentations described in the QTPP which suit paediatrics, adults and older patients. It is recognised that designing medicines for smaller population groups will result in multiple presentations that could lead to smaller manufacturing batch sizes. In the short to medium term; dose flexibility, easy-to-swallow formulations, and easier access packaging are all factors under consideration. Dose flexibility could be achieved with various dosage forms such as oral liquids, mini-tablets, or multi-particulates. Whilst patient dosage preferences are beginning to be understood, further investigation is needed to balance the needs of the patient, care giver, prescriber, and payer. There also remain a number of challenges with the engineering solutions and delivery device for mini-tablets and multi-particulates (aside from filled capsules) to accurately and robustly deliver the dose, and issues with handling the device and the packaging for an older patient. It is also recognised that there are numerous challenges, not least of which is the definition of the older patient and a generic QTPP for an older

    Full Text Available The subway system is an indispensable part of every modern metropolis. Building a subway is no longer a matter of prestige but a necessity, a consequence of the traffic revolution worldwide. This paper shows four metro studies with specific reference to the Belgrade subway and problems that occurred. The first one was conducted in 1946 by the famous Serbian architect Nikola Dobrovic. This document is indeed the first written record discussing the subway issue in Belgrade. The next study dates back to 1968. This project was the first major study on the possibility of a subway. The third and biggest, this subway study was completed in 1982 and contained a major and comprehensive subway project. This project was officially accepted and enacted by the city government. The fourth project in circulation with regard to the subway is the light city railway project. It came out due to the consequences of the decision that a classical subway was not necessary in Belgrade, so that a replacement for the classical subway system was to be undertaken. The light city railway project was adopted as a part of the General Urban Plan for Belgrade by the year 2021.

    Full Text Available Las grandes ciudades del mundo que han resuelto su problema de transporte público lo han logrado principalmente a la luz de las siguientes dos políticas públicas: una expansión significativa de la red de Metro y trenes urbanos, y una firme regulación en el uso del automóvil. La evidencia empírica a nivel mundial ha permitido constatar que la expansión de redes de Metro genera una reducción mucho más efectiva en el uso del transporte privado que otras medidas como por ejemplo subsidiar la tarifa del transporte público. Adicionalmente, la existencia de una importante red de Metro o trenes urbanos permite aumentar notablemente la efectividad de políticas regulatorias al uso del automóvil, como tarificación vial y gravámenes específicos, entre otras, ya que los automovilistas habituales sí ven en el Metro una alternativa real de transporte, no así en los servicios de buses.Large cities around the world that have successfully addressed their public transport problems have made it mainly through the folio wing two public policies: a significant expansion of the Metro or urban train networks, and a tight regulation of the use of automobiles. Empirical evidence worldwide shows that the expansion of the Metro network produces a much more effective reduction in the use of private transport than alternative policies as for instance subsidizing the tariff of public transport. Besides, the existence of an important Metro or urban train network enlarges the effectiveness of other regulatory policies to the use of automobile, as road pricing and specific taxes, since the users of automobiles see in Metro a reasonable alternative of transport, which is not the case for buses.

    Walnut and almond kernels are highly nutritious mainly due to their high oil contents. In this study, 32 factorial experimental designs were used to optimize processes for oil extraction by screw-pressing at industrial scale. Experimental designs included seed moisture content (SMC), and restriction die (RD) as the main processing parameters. Theoretical models were scanned against experimental data in order to optimize oil extraction conditions. The response variables analyzed were oil yield (OY), fine solid content (FC) in oil, and oil quality parameters. Fitted models for OY indicated maximum predicted values similar to the highest experimental values. Walnut oil extractions showed a maximum OY (84.5 ± 2.3 %) at 7.21% SMC, and 10 mm RD. For almond kernels, maximum OY (71.9 ± 3.5%) was obtained at 9.42% SMC, and 12 mm RD. Chemical quality parameters from both oils were in the ranges stated in Codex (FAO/WHO) standards for virgin (non-refined) oils. [Spanish] La nuez y almendra son frutos sumamente nutritivos debido a su alto contenido de aceite. Mediante un diseño experimental de tipo factorial 32 se optimizó el proceso de extracción de estos aceites con prensa de tornillo a escala industrial. Las variables de proceso analizadas fueron el contenido de humedad de la semilla (CHS) y el diámetro de reducción (DR). Los modelos ajustados para rendimiento de aceite (RA) indicaron valores máximos predichos similares a los valores experimentales. Las extracciones de aceite de nuez mostraron un RA máximo (84,5 ± 2,3%) a 7,21% CHS, y 10 mm DR. Para almendra, se obtuvo un máximo de RA (71,9 ± 3,5%) con 9,42% de CHS y 12 mm de DR. Los parámetros de calidad química de ambos aceites se encontraban en los rangos establecidos en las normas del Codex (FAO / OMS) para aceites vírgenes (no refinados).

This study contributes a complex network analysis of the Guangzhou metro. The metro network has 236 kilometers of track and is the 6th busiest metro system of the world. In this paper topological properties of the network are explored. We observed that the network displays small world properties and is assortative in nature. The network possesses a high average degree of 17.5 with a small diameter of 5. Furthermore, we also identified the most important metro stations based on betweenness and closeness centralities. These could help in identifying the probable congestion points in the metro system and provide policy makers with an opportunity to improve the performance of the metro system.

  7. Levels of particulate air pollution, its elemental composition, determinants and health effects in metro systems

    Nieuwenhuijsen, M. J.; Gómez-Perales, J. E.; Colvile, R. N.

    The aim of this study was to review and summarise the levels of particulate air pollution, its elemental composition, its determinants, and its potential health effects in metro systems. A number of studies have been conducted to assess the levels of particulate matter and its chemical composition in metro systems. The monitoring equipment used varied and may have led to different reporting and makes it more difficult to compare results between metro systems. Some of the highest average levels of particulate matter were measured in the London metro system. Whereas some studies have reported higher levels of particulate matter in the metro system (e.g. London, Helsinki, Stockholm) compared to other modes of transport (London) and street canyons (Stockholm and Helsinki), other studies reported lower levels in the metro system (e.g. Hong Kong, Guangzhou, and Mexico City). The differences may be due to different material of the wheel, ventilation levels and breaking systems but there is no good evidence to what extent the differences may be explained by this, except perhaps for some elements (e.g. Fe, Mn). The dust in the metro system was shown to be more toxic than ambient airborne particulates, and its toxicity was compared with welding dust. The higher toxicity may be due to the higher iron content. Although the current levels of particulate matter and toxic matter are unlikely to lead to any significant excess health effects in commuters, they should be reduced where possible. It will be difficult to introduce measures to reduce the levels in older metro systems, e.g. by introducing air conditioning in London, but certainly they should be part of any new designs of metro systems.

    Full Text Available Metro City is a developing city that attracts many new citizens to come and live in the city of Metro. It affects the density and population growth in the city of Metro so it boils down to the increasing need for energy for fuel such as gas and electricity needs. UU No. 33 of 2007 the government seeks to optimize the role of PEMDA and communities and academics to be able to take advantage of the various potential that may be developed in their respective city in meeting energy needs. The survey results show the picture that the city of Metro has potential in the utilization of biogas energy. The availability of this organic material is quite common in Metro city. But the availability of the material has not been classified in number and variety. For that, we need to do research in mapping biogas potential in every area in Metro city. The research method used is the method of documentation, observation, and interview. As for data analysis techniques, conducted qualitatively and quantitatively through the findings of observations in the form of descriptions, calculation analysis, and tabulation. The results obtained show that the North Metro sub-district has the highest potential for biogas development. The most common materials are animal waste derived from cow dung as much as 84% and biogas from plants that are from rice straw (54% and Tahu/tempe processing waste (38%. Other organic ingredients found are chicken, goat, buffalo, and banana peels. This result shows that the biogas potency of Metro City is best developed that is through the use of cow dung

    This chapter addresses past, ongoing, and short (to 2010) and medium-term (to 2030) future actions that can be taken to mitigate GHG emissions from the manufacturing and process industries. Globally, and in most countries, CO{sub 2} accounts for more than 90% of CO{sub 2}-eq GHG emissions from the industrial sector (Price et al., 2006; US EPA, 2006b). These CO{sub 2} emissions arise from three sources: (1) the use of fossil fuels for energy, either directly by industry for heat and power generation or indirectly in the generation of purchased electricity and steam; (2) non-energy uses of fossil fuels in chemical processing and metal smelting; and (3) non-fossil fuel sources, for example cement and lime manufacture. Industrial processes also emit other GHGs, e.g.: (1) Nitrous oxide (N{sub 2}O) is emitted as a byproduct of adipic acid, nitric acid and caprolactam production; (2) HFC-23 is emitted as a byproduct of HCFC-22 production, a refrigerant, and also used in fluoroplastics manufacture; (3) Perfluorocarbons (PFCs) are emitted as byproducts of aluminium smelting and in semiconductor manufacture; (4) Sulphur hexafluoride (SF{sub 6}) is emitted in the manufacture, use and, decommissioning of gas insulated electrical switchgear, during the production of flat screen panels and semiconductors, from magnesium die casting and other industrial applications; (5) Methane (CH{sub 4}) is emitted as a byproduct of some chemical processes; and (6) CH{sub 4} and N{sub 2}O can be emitted by food industry waste streams. Many GHG emission mitigation options have been developed for the industrial sector. They fall into three categories: operating procedures, sector-wide technologies and process-specific technologies. A sampling of these options is discussed in Sections 7.2-7.4. The short- and medium-term potential for and cost of all classes of options are discussed in Section 7.5, barriers to the application of these options are addressed in Section 7.6 and the implication of

    A campaign was conducted to assess and compare the air quality at the different metro platforms at Shanghai City, focusing on particulate matter (PM) levels, chemical compositions, morphology and mineralogy, as well as species of iron. Our results indicated that the average PM{sub 2.5} concentrations for the three metro lines were 177.7 μg/m{sup 3}, 105.7 μg/m{sup 3} and 82.5 μg/m{sup 3}, respectively, and the average PM{sub 1} concentrations for the three lines were 122.3 μg/m{sup 3}, 84.1 μg/m{sup 3} and 59.6 μg/m{sup 3}, respectively. Fe, Mn, Cr, Cu, Sr, Ba and Pb concentrations in all of the sampling sites were significantly higher than that in the urban ambient air, implicating that these trace metals may be associated with the metro systems working. Individual airborne dusts were studied for morphology and mineralogy characteristics. The results revealed that the presence of most individual particles were with no definite shape and most of them were with a large metal content. Furthermore, Fe-rich particles had significantly higher abundance in the metro systems, which were more frequently encountered in the underground lines than the aboveground line. The 2D distribution map of an interested Fe-rich particle showed an uneven Fe distribution, implying that a hollow or core of other substance exists in the particle center during the formation process. Cluster analysis revealed that Fe-rich particles were possibly a mixture of Fe species. Fitting of X-ray absorption near-edge fine structure spectra (XANES) showed the main iron species within the particles collected from the three contrasting metro lines of Shanghai to be hematite, magnetite, iron-metal and mineral Fe. Hematite and mineral Fe were all found in three lines, while magnetite only existed in aboveground metro line. Iron-metal was determined in both the older and younger underground lines, based on the X-ray diffraction (XRD) analysis. As diverse Fe species have different physical

    Nearly 40 years of research provides an extensive body of evidence about human health, well-being, and improved function benefits associated with experiences of nearby nature in cities. We demonstrate the numerous opportunities for future research efforts that link metro nature, human health and well-being outcomes, and economic values. We reviewed the literature on urban nature-based health and well-being benefits. In this review, we provide a classification schematic and propose potential economic values associated with metro nature services. Economic valuation of benefits derived from urban green systems has largely been undertaken in the fields of environmental and natural resource economics, but studies have not typically addressed health outcomes. Urban trees, parks, gardens, open spaces, and other nearby nature elements-collectively termed metro nature-generate many positive externalities that have been largely overlooked in urban economics and policy. Here, we present a range of health benefits, including benefit context and beneficiaries. Although the understanding of these benefits is not yet consistently expressed, and although it is likely that attempts to link urban ecosystem services and economic values will not include all expressions of cultural or social value, the development of new interdisciplinary approaches that integrate environmental health and economic disciplines are greatly needed. Metro nature provides diverse and substantial benefits to human populations in cities. In this review, we begin to address the need for development of valuation methodologies and new approaches to understanding the potential economic outcomes of these benefits.

    Full Text Available Evaluation of spatial accessibility to public transportation has a weak background in many emerging countries, including Iran. Transit-Oriented Development is of great interest among Iranian planners and academics, but little is known about transit orientation provided by major public transport systems exemplified by the Tehran Metro. Statistical difference tests and polynomial regression done in this study show how residential densities within walking distances of metro stations established at different times after 1998 are significantly different. Both population and employment densities have decreased in more recent stations compared to those opened between 2005 and 2010. Moreover, one-way T-Tests comparing the population and densities of older lines with those of newer lines reveal that, in most cases, densities within walking distances of stations of older lines are higher. The paper concludes that lack of proper site selection and failing to locate new stations near job centers and highly populated areas threatens the transit-friendliness that emerged in the early years after establishing the first metro station in 1998.

    2017-10-01

    The air quality in the subway metro indoor microenvironment has been of particular public concern. With specific reference to the growing demand of green transportation and sustainable development, subway metro systems have been rapidly developed worldwide in last decades. The number of metro commuters has continuously increased over recent years in metropolitan cities. In some cities, metro system has become the primary public transportation mode. Although commuters typically spend only 30-40min in metros, the air pollutants emitted from various interior components of metro system as well as air pollutants carried by ventilation supply air are significant sources of harmful air pollutants that could lead to unhealthy human exposure. Commuters' exposure to various air pollutants in metro carriages may cause perceivable health risk as reported by many environmental health studies. This review summarizes significant findings in the literature on air quality inside metro indoor environment, including pollutant concentration levels, chemical species, related sources and health risk assessment. More than 160 relevant studies performed across over 20 countries were carefully reviewed. These comprised more than 2000 individual measurement trips. Particulate matters, aromatic hydrocarbons, carbonyls and airborne bacteria have been identified as the primary air pollutants inside metro system. On this basis, future work could focus on investigating the chronic health risks of exposure to various air pollutants other than PM, and/or further developing advanced air purification unit to improve metro in-station air quality.

    Full Text Available Transit-oriented development (TOD, as a sustainable supporting strategy, emphasizes the improvement of public transportation coverage and quality, land use density and diversity of around public transportation stations and priority of walking and cycling at station areas. Traffic, environmental and economic problems arising from high growth of personal car, inappropriate distribution of land use, and car-orientation of metropolitan area, necessitate adoption of TOD. In recent years, more researches on urban development and transportation have focused on this strategy. This research considering metro stations as base for development, aims to model metro users' travel behavior and decision-making procedures. In this regard, research question is: what are the parameters or factors affecting in the frequency of travel by metro in half-mile radius from stations. The radius was determine based on TOD definitions and 5 minute walking time to metro stations.  A questionnaire was designed in three sections that including travel features by metro, attitudes toward metro, economic and social characteristics of respondents. Ten stations were selected based on their geographic dispersion in Tehran and a sample of 450 respondents was determined. The questionnaires were surveyed face to face in (half-mile vicinity of metro stations. Based on a refined sample on 400 questionnaires ordered discrete choice models were considered. Results of descriptive statistics show that 38.5 percent of the sample used metro more than 4 times per week. Trip purpose for 45.7 percent of metro users is work. Access mode to the metro stations for nearly half of the users (47.6 percent is bus. Results of ordered logit models show a number of significant variables including: habit of using the metro, waiting time in station, trip purpose (working, shopping and recreation, personal car access mode to the metro station, walking access mode to the metro station and being a housewife.

    Full Text Available While having many positive impacts, a tremendous economic performance and rapid industrial expansion over the last decades in the Philippines has had negative effects that have resulted in unfavorable hydrological and ecological changes in most urban river systems and has created environmental problems. Usually, these effects would not be part of a systematic assessment of urban water benefits. To address the issue, this study investigates the relationship between poor water quality and resident’s willingness to pay (WTP for improved water quality in Metro Manila. By employing a contingent valuation method (CVM, this paper estimates the benefits of the provision of clean water quality (swimmable and fishable in waterbodies of Metro Manila for its residents. Face-to-face interviews were completed with 240 randomly selected residents. Residents expressed a mean WTP of PHP102.44 (USD2.03 for a swimmable water quality (good quality and a mean WTP of PHP102.39 (USD2.03 for fishable water quality (moderate quality. The aggregation of this mean willingness-to-pay value amounted to annual economic benefits from PHP9443 billion to PHP9447 billion (approx. USD190 million per year for all taxpayers in Metro Manila. As expected, these estimates could inform local decision-makers about the benefits of future policy interventions aimed at improving the quality of waterbodies in Metro Manila.

    With the large-scale application of metro MSTP in recent two years, a lot of problems have emerged inevitably. Some more advanced technologies or mechanisms are needed to deal with the application problems of current version MSTP. RPR and MPLS become new focus of enhanced MSTP"s features and the combination of them will boost maturity and further development of enhanced metro MSTP. The MSTP embedded with RPR and MPLS not only find a solution for perfect transport of TDM service, but also improve the support ability for data traffic and bandwidth utilization. With the help of enhanced MSTP, it"s easy for network carriers to provide a reliable, cost-effective, flexible and competitive transport infrastructure delivering various advanced services. RPR firstly solves the conflict between the transport efficiency and QoS of packet service via some mechanisms such as dual counter-rotating ringlet, statistical multiplexing, bandwidth sharing, topology discovery, fairness control etc. Secondly, RPR guarantees the QoS of subscriber by strict service classification and priority. Thirdly, RPR can provide the carrier-class protection within 50ms. On the other hand, MPLS can solve the lack of VLAN ID by LSP labeling and in addition it offers VPN service for different customers then enhances the SLA. Most of all, MPLS provide cross-networking ability, end-to-end service configuration and QoS guarantee, traffic engineering and network optimization. Enhanced MSTP will be applied in convergence or access layer of metro network first. It could have the function of RPR and MPLS at the same time, the reconciliation sub-layer should adopts GFP or LAPS encapsulation, the mapping granularity can be based on VC-12/VC3/VC4-Xc/v and the LCAS should be supported when the transmission channels are configured by virtual concatenation. Enhanced MSTP can be used to build either a single ring network or multi-ring network for improving the ability and quality of Ethernet transportation and

    Villalba Sanchis, I.; Salvador Zuriaga, P.

    2016-07-01

    Nowadays one of the main priorities for metro line operators is the reduction of energy consumption, due to the environmental impact and economic cost. In order to achieve this objective different strategies can be applied, normally focused into rolling stock, infrastructure and/or operation. Considering short-term measures and related to the traffic operation strategies, different approaches are being researched. One of the most effective strategy which reduce net energy consumption is the use of efficient driving techniques. These techniques produces a speed profile between two stations that requires the minimum net energy consumption, without degrading commercial running times or passenger comfort. In this paper, a computer model for calculating the metro vehicles speed profiles minimizing the energy consumption was developed. The equations considered in the model represent the behavior of a single vehicle operated under manual driving, subject to different constraints such as the headway, cycle time, distances and acceleration limits. The proposed model calculates different commands to be systematically executed by the driver. The resulting simulator has been tuned by means of on board measurements of speed, accelerations and energy consumption obtained along different lines in Metro de Valencia network. For this purpose, different scenarios are analyzed to assess the achievable energy savings. In general terms and comparing with the actual energy consumption, the solutions proposed can reduce the net energy consumption around 19%. (Author)

    Bechtel, James H.

    Metro optical networks provide an enticing opportunity for strengthening homeland security. Many existing and emerging fiber-optic networks can be adapted for enhanced security applications. Applications include airports, theme parks, sports venues, and border surveillance systems. Here real-time high-quality video and captured images can be collected, transported, processed, and stored for security applications. Video and data collection are important also at correctional facilities, courts, infrastructure (e.g., dams, bridges, railroads, reservoirs, power stations), and at military and other government locations. The scaling of DWDM-based networks allows vast amounts of data to be collected and transported including biometric features of individuals at security check points. Here applications will be discussed along with potential solutions and challenges. Examples of solutions to these problems are given. This includes a discussion of metropolitan aggregation platforms for voice, video, and data that are SONET compliant for use in SONET networks and the use of DWDM technology for scaling and transporting a variety of protocols. Element management software allows not only network status monitoring, but also provides optimized allocation of network resources through the use of optical switches or electrical cross connects.

    2000-01-01

    Purpose: To evaluate the in vitro cytotoxic and radiopotentiating effects of a novel paclitaxel analog (taxoltere metro) on Chinese hamster ovary (CHO) cells and human colon cancer cells. Methods and Materials: Three cell lines (CHO cells, HCT116 human colon carcinoma cells [paclitaxel-sensitive], and VM46 cells [paclitaxel-resistant subline of HCT116]) were employed in this study. Cell survival was determined using the standard colony-forming assay. The ID 50 value (drug concentrations required to reduce colony formation to 50% of the control value) was determined as a cytotoxic index from each cell survival curve. The sensitizer enhancement ratio (SER) as a radiopotentiating endpoint was determined as the ratio of the D 0 values (with or without drugs) under hypoxic or air conditions. Results: Taxoltere metro was 5-15 times more effective in killing CHO cells than paclitaxel under both hypoxic and euoxic treatment conditions. Cytocidal effects of taxoltere metro on HCT116 cells and VM46 cells were 28 and 70 times higher than those of paclitaxel (p < 0.001), respectively. Taxoltere metro also produced significant radiopotentiating effects on euoxic CHO and HCT116 cells, but not on hypoxic cells. The SER value of taxoltere metro for CHO cells was about 2.3 at a dose of 100 nM. With HCT116 cells, taxoltere metro yielded an SER of 1.2 at the low dose of 10 nM. In contrast, the parent compound paclitaxel yielded little or no radiosensitization with either CHO or HCT116 cells. Conclusion: The results demonstrate that taxoltere metro is significantly more potent than paclitaxel in chemoradiopotentiating CHO cells and HCT116 human colon carcinoma cells. The data strongly suggest that taxoltere metro could be a promising chemoradiopotentiating agent for treatment of cancer

    2016-01-01

    Highlights: • Lighting systems are big energy consumers in underground metro stations. • An adaptive lighting system strategy is developed for underground stations. • Dimming controls are based on station occupancy levels and maintenance cycles. • The k-means clustering technique is used to identify stations’ occupancy patterns. • Savings were found to amount to 255.47 MW h in 2 years for a case study metro network. - Abstract: Lighting systems are usually one of the largest electrical end-uses in underground metro stations. Taking into account that budget restrictions in publicly owned companies hinder energy efficiency retrofit projects that require high initial investments, affordable energy saving strategies are needed. This paper presents a low-cost approach for reducing lighting electricity use in underground stations, without affecting passengers’ comfort or the metro operator’s service. For this purpose, an adaptive lighting strategy of dimming the illuminance levels of artificial light sources has been developed. Dimming controls are based on the occupancy of the station, and the preventive maintenance and cleaning cycles of the luminaires. The stations’ monthly occupancy patterns are defined through the k-means clustering technique. To illustrate its effectiveness, the method was applied to 115 underground stations of the Barcelona metro network. The results revealed overall electricity savings of 255.47 MW h on a biannual basis, which represents 36.22% of the stations’ baseline lighting consumption. Individual energy savings were found to range from 25 to 87.5 MW h/year in the stations of the Barcelona metro network, depending on the number and profile of station users. The research findings will undoubtedly be useful for the future energy efficiency project plans of worldwide metro operators and managers of other underground spaces.

    A modal shift occurs when one mode of transport has a comparative advantage in a similar market over another. The present work concerns with the development of modal shift model for urban travel in Chennai, India. The modal shift model was calibrated using binary logit technique and validated using hold-out sample method. The validated model was used to predict the probability of shift in selected corridor. The recent introduction of metro rail in Chennai has lead to an increasing competition among public transport modes. To study the influence of metro on bus transport, a Stated Preference (SP) survey was conducted among express bus travellers. Using the SP survey data, a modal shift model was calibrated to estimate the plausible shift from bus to metro. Results indicate that variables like fare- difference, age, and income play an important role in the shift behaviour. When metro fare increases with respect to express bus fare, bus passengers are less willing to use metro and vice-versa.

  18. Radon exposure of passengers in the Prague metro

    Sabol, J.

    1996-01-01

    This paper summarises the results of radon concentration monitoring in the carriages and at some stations of the Prague Metro network. The measurements revealed that radon levels in the Metro are relatively low in comparison to those normally encountered in dwellings in the Prague region. On average, the radon concentrations in the air inside the carriages have been found to be about 11 - 12 Bq m -3 while the levels at most stations reached values between 10 and 15 Bq m -3 . The Metro is intensively ventilated by means of powerful blowers and fans; the piston effect of the moving trains also contributes to air exchange. The ventilation rate is typically 3-4 h -1 . The highest rate is in line C, where the air in all underground areas is completely exchanged 6 times within each hour. These results demonstrate that Metro passengers receive about the same effective dose as passengers using surface transport. The doses from radon in the metro are only slightly higher than radon-related doses in the open air, while exposure due to external photon radiation seems to be a few percent lower than dose rates common in typical Czech houses.

    problem have severely hindered the rate of return on the investment from an economical viewpoint, let alone 100Gb/s transmission. In addition, to enable fast turn-up of new services and reduce network operation costs, carriers are also deploying reconfigurable optical add/drop multiplexers (ROADMs) and transparent optical networks. ROADMs impose more impairments to transmitted signals and are important considerations in designing backbone transmission links. Recently, advanced modulation schemes have been investigated in both the academia and industry as ways to improve the spectral efficiency and alleviate transmission impairments. Signal processing techniques familiar to traditional telecommunication engineers are also playing more and more important roles in optical communications because of the fast advance in mixed signal processing and growing abundance of computational power. In this invited talk, we review the current challenges faced in upgrading existing 10Gb/s metro and regional WDM networks and the potential solutions to enable 40 and 100Gb/s wavelength services.

    Urban floods from thunderstorms cause severe problems in Metro Manila due to road traffic. Using Light Detection and Ranging (LiDAR)-derived topography, flood simulations and anecdotal reports, the root of surface flood problems in Metro Manila is identified. Majority of flood-prone areas are along the intersection of creeks and streets located in topographic lows. When creeks overflow or when rapidly accumulated street flood does not drain fast enough to the nearest stream channel, the intersecting road also gets flooded. Possible solutions include the elevation of roads or construction of well-designed drainage structures leading to the creeks. Proposed solutions to the flood problem of Metro Manila may avoid paralyzing traffic problems due to short-lived rain events, which according to Japan International Cooperation Agency (JICA) cost the Philippine economy 2.4billionpesos/day.

    Full Text Available One of the most common and important sources of noise in the residential environments are vehicles such as airplanes and subways. Trafficking of vehicles in streets and highways, psychologically, have damaging impacts on people living close to such areas. The development and expansion of the trading and industrial units is another factor that causes more and more exposure to noise.We have aimed at measuring the noises caused by vibration of subways of the Line of Karaj-Tehran-Mehrshahr and its effect on its surrounding area.To study this effect we designed a mathematical model and put the information of this subway line in the mentioned model. Then we analyzed the findings.This model demonstrated that we can control the harsh noise of the subway by reducing the speed of the train to 60Km/h in some points and increase in other parts to 130Km/h.

    In 1988, former President Corazon Aquino created the Presidential Task Force on Traffic Management to formulate plans and programs to improve the traffic situation in Metro Manila and to address the emerging problem of air pollution and concern on renewable energy sources for transportation. The Task Force formulated the Metro Manila Traffic Improvement Plan (TRIP) which was approved by President Aquino for implementation. TRIP called for the development of a mass urban transport system, which included the expansion of the light rail transit system and the construction and improvement of the Metro Manila road network. Culled mainly from the TRIP proposals, the Updated Transport and Traffic Management Plan for Metro Manila (1993-1998) was developed through interagency discussions, public consultations, data collation and research work. This plan is directed towards the development of a more responsive public transport system, expansion of road network capacity, and improvement of traffic management and enforcement. Constraints may be present along the way but opportunities and potentials exist for the deliverance of daily commuters struggling to make a living.

    2001-01-01

    Results of a four-year study on somatic mutation in peripheral blood lymphocytes among Metro Manila residents as an indicator of exposure to environmental pollution conducted by the Philippine Nuclear Research Institute (PNRI) is presented. The study which involves mutation indexing of 200 blood donors demonstrated very strong correlation between high levels of ambient air pollution and increase incidence of mutation at the specific gene locus in peripheral blood lymphocytes among residents of specific areas in Metro Manila. Using the PNRI adapted protocol to determine incidence of mutation at a specific gene marker, hypoxanthine guanine phosphoribosyl transferase (HGPRT), our database analysis indicated a statistically significant difference between mean mutation index of blood donors residing in an area with lower level of pollution (Las Pinas) compared to those residents living in areas with the highest estimated pollution level (Valenzuela). The results of the statistical analyses should provide regulators the direction in incorporating the data into their pollution abatement program to maximize health impact. Biomarker analysis should play a greater role in the future in the formulation of national environment policies. The temporal variation of these ''aseline data'' as the Philippine moves forward through the next several years in its industrialization program should in itself be a very valuable source of environmental policy instruments.

    2010-01-01

    This paper presents MetroMap, a new graphical representation model for controlling and managing the software development process. Metromap uses metaphors and visual representation techniques to explore several key indicators in order to support problem detection and resolution. The resulting visualization addresses diverse management tasks, such as tracking of deviations from the plan, analysis of patterns of failure detection and correction, overall assessment of change management policies, and estimation of product quality. The proposed visualization uses a metaphor with a metro map along with various interactive techniques to represent information concerning the software development process and to deal efficiently with multivariate visual queries. Finally, the paper shows the implementation of the tool in JavaFX with data of a real project and the results of testing the tool with the aforementioned data and users attempting several information retrieval tasks. The conclusion shows the results of analyzing user response time and efficiency using the MetroMap visualization system. The utility of the tool was positively evaluated.

    Full Text Available In article was formulated and solved the problem of conditional nonlinear technical and economic optimization of the distance between intermediate supports, uniform in height, during the design of the cable metro lines in highly urban-ized city environment. The optimization problem involves a single-criterion objective function that expresses the cost of construction of the cable metro line (total cost of intermediate supports and their foundations, traction and carrying steel cables and technical equipment. The specified objective function subject to minimization by finding the optimal combination of the distance between intermediate supports and tension carrying ropes with accounting constructive, modal, structural and planning constraints in the form of nonlinear inequalities. The optimization algorithm was based on the direct method of optimization type, Hooke-Jeeves, which was modified taking into account the need of varying the height of intermediate supports with a constant step equal to the step of unification. When constructing the objective function were considered three possible forms sagging of carrying ropes, which can be implemented for various values of the efforts of their tension. Analysis was done of the influence of the step unification and minimum size of interme-diate supports on their optimum step, the cost of intermediate supports, the cost of 1 km cable metro line for different values of the angle of the longitudinal slope of the surface relief along the cable metro line. The graph of height of uni-fied supports from the angle of the longitudinal slope of the surface relief has discrete-step type. With the increase of the step unify the discreteness increases: the width of the range of angles of the longitudinal slope of the surface relief within which the height of the supports remains constant, increases.

    2002-02-01

    Full Text Available Piezoelectric ceramic materials have an important number of applications that is continuing increasing. One of these applications is as driving element in the design of an accelerometer. They may be used in monitoring vibration for the automobile and aeroespacial industries and robotic or civil engineering. The cymbal transducer is a good candidate for accelerometer applications due to its high effective piezoelectric charge coefficients. In this work it is shown that changes in the geometry and size of the caps improve the performance of the sensor. The sensitivity of the cymbal accelerometer increases with decreasing cap size. The mechanical vibration response of the cymbal is studied and different properties, like resonant frequency, electromechanical coupling coefficient, and fastest response time are compared.

    Los materiales cerámicos piezoeléctricos presentan un número importante y en continuo aumento de aplicaciones. Entre éstas su utilización como elementos activos en el diseño de acelerómetros posibilita el control de vibraciones en la industria del transporte, aerospacial, robótica e ingeniería civil entre otras. Entre los múltiples diseños como material compuesto destaca, gracias a sus elevados coeficientes de carga efectivos, el denominado tipo címbalo. En este trabajo se comprueba que modificando la geometría y el tamaño de las cápsulas se optimiza el comportamiento del sensor. Concretamente una disminución en el tamaño de las cápsulas se traduce en un aumento de la sensibilidad del acelerómetro. También se muestran los espectros de impedancia y se comparan distintas propiedades como son la frecuencia de resonancia, coeficiente de acoplo electromecánico y tiempo mínimo de respuesta.

  17. Soil Investigation Aspects of a Complex Metro Project in Amsterdam

    Science.gov (United States)

    Herbschleb, Jurgen

    The municipality of Amsterdam wishes to reduce the level of car traffic within the City Centre. As a consequence the public transport is to be extended by a new (bored) North/South Metro line. The excavation depths for the stations will exceed 30 m and will be constructed in difficult soft soil conditions. A further significant aspect is that the building pits are very near (3 to 5 m) to buildings of historical importance. The design philosophy of the station boxes was to determine an acceptable balance between the safety requirements and construction costs. The guidelines for the design, both for the building pits and the bored tunnel, are the predicted deformations of the adjacent building foundations. One of the more important geotechnical risks for this project is incorrect determination of the deformations arising from the building processes alongside the route of the metro. As such it should be realised that advanced finite element programs with second order material models require different geotechnical parameters than analytical models. The careful selection of calculation (soil) models, the level of safety (risk analysis), and site investigation is the start of the determination of the geotechnical parameters. This paper will focus on the interpretation of the site investigation for this complex project and will concentrate on the process followed, the problems encountered with the interpretation, the obtained results, and the used tools for geotechnical risk management.

  19. Measuring Crowdedness between Adjacent Stations in an Urban Metro System: a Chinese Case Study

    Directory of Open Access Journals (Sweden)

    2017-12-01

    Full Text Available The urban metro system has been widely appreciated as the most important component in urban infrastructures. It plays a critical role in promoting urban social and economic development, and particularly in reducing the urban traffic congestion. However, there are various inherent problems with operating metro systems, which typically involve the crowdedness both at stations and inside vehicles. Both policymakers and academic researchers in China have paid little attention to the crowdedness between metro stations. In order to solve the problem of crowdedness, it is necessary to develop a method to evaluate the level of crowdedness. This work establishes a model to measure the crowdedness between adjacent stations in a metro system based on the load factor principle, passenger standing density, and other factors such as the metro operation schedule and estimations of passenger flows. The Chongqing Metro Line 3 in China is used as a case study to demonstrate the application of the evaluation model. The case study reveals that the model introduced in this study can assist with assessing the crowdedness level between adjacent stations in a metro line. The model is an effective tool for helping the metro management and administration understand the level of crowdedness, apply proper methods to mitigate the crowdedness, and thus improve the quality of the service for those utilizing the metro system.

    Flint, Douglas H

    2003-01-01

    This study has two objectives. First, to predict the outcomes of a public sector downsizing; second to measure effects of downsizing at organizational and inter-organizational levels. Primary data to assess the organizational level effects was collected through interviews with senior executives at two of Metro-Toronto's hospitals. Secondary data, to assess the inter-organizational effects, was collected from government documents and media reports. Due to the exploratory nature of the study's objectives a case study method was employed. Most institutional downsizing practices aligned with successful outcomes. Procedures involved at the inter-organizational level aligned with unsuccessful outcomes and negated organizational initiatives. This resulted in an overall alignment with unsuccessful procedures. The implication, based on private sector downsizings, is that the post-downsized hospital system was more costly and less effective.

    This article presents an analysis of social sustainability in comparative theoretical context and as a challenge to the post-political interpretation of sustainability in policy practice at the urban and regional scales. Metro Vancouver provides a case study for improving our understanding of the meaning of social sustainability as a framework for social policy in that it is among the handful of cities around the world currently working to define and enact social sustainability in governance terms. Results of this participant research provide evidence that some cities are politically engaging alternative development pathways using the concept of social sustainability. For sustainable development to retain its promise as an alternative policy framework for cities, social sustainability must be at the forefront.

    Indoor air pollution is an increasing health concern, especially in enclosed environments such as underground subway stations because of increased global usage by urban populations. This study measured the indoor air quality of underground platforms at 10 metro stations of the Taipei Rapid Transit system (TRTS) in Taiwan, including humidity, temperature, carbon monoxide (CO), carbon dioxide (CO₂), formaldehyde (HCHO), total volatile organic compounds (TVOCs), ozone (O₃), airborne particulate matter (PM 10 and PM 2.5 ), bacteria and fungi. Results showed that the CO₂, CO and HCHO levels met the stipulated standards as regulated by Taiwan's Indoor Air Quality Management Act (TIAQMA). However, elevated PM 10 and PM 2.5 levels were measured at most stations. TVOCs and bacterial concentrations at some stations measured in summer were higher than the regulated standards stipulated by Taiwan's Environmental Protection Administration. Further studies should be conducted to reduce particulate matters, TVOCs and bacteria in the air of subway stations.

    enforcements, as well as insufficient user’s knowledge cause our cities inaccessible. Therefore, we have to increase the awareness of our community on accessible city life and transportation systems rather than make laws and hope for recovery. In this context, a case study is intended to examine the approaches on barrier-free design and level of accessibility at metro stations in Turkey. With the scope of this case study, current informative, stimulating and guiding regulations, vertical and horizontal implementations on circulation areas at metro stations are examined by an accessible design control list Accessible design control list consists of 28 questions that have been selected from Turkish Ministry of Family and Social Policies-People with Disabilities and Elderly General Service Accessibility check Lists and Turkish World Handicapped Foundation- Outdoors and Indoors Accessibility Check Lists. With the help of question we can examine the passengers’ expectations on the quality of informative, stimulating and guiding signboards at entrance, circulations and surroundings of metro stations; except the legislations related to the product sizes and constraints that designers or professionals have to obey The questions are answered by disabled passengers who use Kadıkoy Ayrılık Cesme main transmission metro station. Disabled passengers are divided into two subject groups. First subject group consist of 5 visually impaired and partially impaired people. The second subject group consist of 7 wheelchair users. Experimentally, asked all the subject groups to make a journey beginning from the entrance of metro station to the train platforms without getting any help. After they completed their journey, they were requested to answer the questions of control list and describe the positive and negative situations from their experiences. According to the result of examining the approaches on barrier-free design and the level of accessibility at Ayrılıkcesme main transmission

    2015-01-01

    The aim of this pilot study was to present examples of extremely low-frequency (ELF) magnetic fields in a Finnish metro station. The metro trains are powered by 750 V DC voltage supplied through a conductor rail next to the running rails. We measured magnetic fields with a magnetic field meter MFM 3000 in 17 cases when a train was leaving the platform in the same metro station. The maximum measured magnetic field was 5400 nT (at 1 m height and 4.3 m from the conductor rail). The magnetic field stayed at this level for a very short time after the metro left the platform. It is possible that there are also DC magnetic fields near the metro as the train leaves the station because the trains are powered by DC voltage. Therefore, it is also important to measure DC fields and DC currents in the future. (authors)

    To determine the peak bone mass density among residents of Metro Manila using dual x-ray absorptiometry (DEXA).The design used is cross-sectional study. The study include 23 females and 22 males, with 3 to 4 subjects for each age range of 5. The methods used was bone mass density measurements on the lumbar spine and the femur using dual x-ray absorptiometry (DPXI lunar) were taken. The values were also age-matched and matched with that of a young adult based on programmed Caucasian norm provided by Lunar Co. The values were then scattered against age for each sex. Ten (10) cc of blood was also extracted from the patients, with 5 cc of blood separated for future studies. Patients were also interviewed as to their lifestyle, diet, use of contraceptive pill or hormonal replacement treatment, using a Filipino version of the revised questionnaire on the WHO Study on osteoporosis. The mean bone mass density at the L21.4 level for females was 1.12±0.11 g/cm 2 and 0,91±0.11 g/cm 2 at the femur. The highest BMD in both the lumbar spine femoral neck measurements among females was achieved between the ages 30-35 years of age with the lowest BMD occurring between 15-20 yrs. old and incidentally in 2 subjects with ages between 40-44. There seems to be little bone loss among beyond the age 35, unlike in the females. Bone mass density among a sample Metro Manila residents was determined using DEXA and the measurements on the lumbar spine and femoral neck. These were age-matched with that of young adult based on Caucasian norm provided by the Lunar Co. Peak bone mass density in the L2L4 level among the females is reached between the ages 30-35 years old, after which there is progressive bone loss with values in the 45-50 years old approximating the values in the 15-19 years old age range. A similar pattern is seen in the measurements taken at the femoral neck. Among males, the peak BMD is reached during the 30-35 years old, but there seems to be no rapid decline or rapid bone

    Full Text Available The graph theory gives a mathematical representation of transport networks and allows us to study their characteristics effectively. A research of the structure of metro system has been conducted in the study by using the graph theory. The study includes subway systems of 22 European capitals. New indicators have been defined in the research such as a degree of routing, a connectivity of the route, average length per link (which takes into account the number of routes, intensity of the route, density of the route. The new and the existing indicators have been used to analyze and classify the metro networks. The statistical method cluster analysis has been applied to classify the networks. Ten indicators have been used to carry out an analysis. The metro systems in European capitals have been classified in three clusters. The first cluster includes large metro systems, the second one includes small metro networks whereas the third cluster includes metro networks with only one line. The combination of both two methods has been used for the first time in this research. The methodology could be used to evaluate other existing metro networks as well as for preliminary analysis in the design of subway systems.

OBJETIVOS: Verificar a confiabilidade inter e intraexaminadores das medidas realizadas pelo goniômetro e inclinômetro na avaliação da ADM de flexão e extensão de joelho e cotovelo, e determinar o erro padrão da medição (EPM dos instrumentos em questão. MÉTODOS: Foi avaliada ADM de flexão e extensão de cotovelo e joelho, bilateralmente, de uma amostra de indivíduos jovens saudáveis do gênero masculino, com faixa etária entre 18 e 30 anos, utilizando um inclinômetro digital e um goniômetro universal. RESULTADOS: A confiabilidade interexaminador variou de pequena a muito alta para os dois instrumentos, apresentando CCI de 0,24 a 0,96 para as medidas feitas com o goniômetro, e de 0,02 a 0,98 para o inclinômetro. O único movimento que obteve confiabilidade muito alta para ambos os aparelhos e examinadores foi a flexão de joelho. O EPM determinado por meio da goniometria e inclinometria variou entre 0,21 e 12,75 graus. CONCLUSÃO: O inclinômetro digital apresenta melhores índices de confiabilidade que o goniômetro para as medidas de ADM. Apenas quatro medidas obtiveram CCI alto e EPM abaixo de dois graus, e, assim, foram consideradas apropriadas para serem utilizadas clinicamente, todas essas realizadas com o inclinômetro.

    Energy Technology Data Exchange (ETDEWEB)

    2017-05-22

    The U.S. Federal Transit Administration (FTA) funds a variety of research projects that support the commercialization of zero-emission bus technology. To evaluate projects funded through these programs, FTA has enlisted the help of the National Renewable Energy Laboratory (NREL) to conduct third-party evaluations of the technologies deployed under the FTA programs. NREL works with the selected agencies to evaluate the performance of the zero-emission buses compared to baseline conventional buses in similar service. The evaluation effort will advance the knowledge base of zero-emission technologies in transit bus applications and provide 'lessons learned' to aid other fleets in incrementally introducing next generation zero-emission buses into their operations. This report provides preliminary performance evaluation results from a demonstration of three zero-emission battery electric buses at King County Metro in King County, Washington. NREL developed this preliminary results report to quickly disseminate evaluation results to stakeholders. Detailed evaluation results will be published in future reports.

    The Greater Vancouver Regional District (GVRD) developed an air quality management plan (AQMP) in 2005 as a means of addressing air quality issues in the region. The plan required progress reports every 2 years as well as a comprehensive review every 5 years. The AQMP established goals to minimize risk to public health from air pollution, improve visibility, and minimize the region's contributions to global climatic change by reducing emissions; implementing local air quality management programs; and enhancing air quality information and public awareness. The AQMP also included a sustainability framework for GVRD's policies and regulations related to regional growth, service delivery and political leadership. Regional strategies for solid waste and liquid waste management were developed in 2008. The sustainability framework has developed 3 priority goals: (1) to reduce diesel particulates by 75 per cent from Metro Vancouver corporate sources by 2012, (2) to be carbon neutral by 2012 excluding solid waste operations, and (3) to reduce regional GHGs by 15 per cent by 2015, and 33 per cent by 2020. Progress updates on regional planning efforts for the AQMP were presented. The report also outlined trends and performance measures used by the GVRD, and discussed changes in air quality issues and priorities that have occurred since the AQMP was adopted in 2005. 1 tab., 8 figs.

    Full Text Available The main objective of this study was to understand the concerns and problems faced by older people in an industrializing middle-income country, Malaysia, in their process of acquiring products to meet their everyday needs. Respondents aged 55 and over were interviewed in eight states throughout Peninsular Malaysia providing 1356 usable questionnaires; two-thirds from urban and one-third from rural areas. Education, health status, and life satisfaction were recorded. Service patronage behaviour was examined for four main categories of commonly-sought consumer goods: groceries, health supplements, apparel, eating outlets, plus selected services (public transport, vacation packages and financial services. The findings showed that older adults in Malaysia are rather discerning consumers. Many respondents are price conscious and have developed consumer attitudes with regard to attitude of staff and assistance rendered. Many display a good ability to discriminate and to select, especially on the basis of price and durability of products and many appear to be acting as effectively as consumers in any other age group.

    2015-12-01

    Metro depots are where subway trains are parked and where maintenance is carried out. They usually occupy the largest ground areas in metro projects. Due to land utilization problems, Chinese cities have begun to develop over-track buildings above metro depots for people's life and work. The frequently moving trains, when going into and out of metro depots, can cause excessive vibration and noise to over-track buildings and adversely affect the living quality of the building occupants. Considering the current need of reliable experimental data for the construction of metro depots, field measurements of vibration and noise on the ground and inside a nearby 3-story building subjected to moving subway trains were conducted in a metro depot at Guangzhou, China. The amplitudes and frequency contents of velocity levels were quantified and compared. The composite A-weighted equivalent sound levels and maximum sound levels were captured. The predicted models for vibration and noise of metro depot were proposed based on existing models and verified. It was found that the vertical vibrations were significantly greater than the horizontal vibrations on the ground and inside the building near the testing line. While at the throat area, the horizontal vibrations near the curved track were remarkably greater than the vertical vibrations. The attenuation of the vibrations with frequencies above 50 Hz was larger than the ones below 50 Hz, and the frequencies of vibration transmitting to adjacent buildings were mainly within 10-50 Hz. The largest equivalent sound level generated in the throat area was smaller than the testing line one, but the instantaneous maximum sound level induced by wheels squeal, contact between wheels and rail joints as well as turnout was close to or even greater than the testing line one. The predicted models gave a first estimation for design and assessment of newly built metro depots. Copyright © 2015 Elsevier B.V. All rights reserved.

    With the rapid development of urbanization in China, the number and size of metro construction projects are increasing quickly. At the same time, and increasing number of accidents in metro construction make it a disturbing focus of social attention. In order to improve safety management in metro construction, an investigation of the participants' perspectives on safety factors in China metro construction has been conducted to identify the key safety factors, and their ranking consistency among the main participants, including clients, consultants, designers, contractors and supervisors. The result of factor analysis indicates that there are five key factors which influence the safety of metro construction including safety attitude, construction site safety, government supervision, market restrictions and task unpredictability. In addition, ANOVA and Spearman rank correlation coefficients were performed to test the consistency of the means rating and the ranking of safety factors. The results indicated that the main participants have significant disagreement about the importance of safety factors on more than half of the items. Suggestions and recommendations on practical countermeasures to improve metro construction safety management in China are proposed. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Highlights: ► Super-capacitors are used to store regenerative braking energy in a metro network. ► A novel approach is proposed to model easily and accurately the metro network. ► An efficient approach is proposed to calculate the required super-capacitors. ► Maximum energy saving is around 44% at off-peak period and 42% at peak period. ► Benefit/cost analyses are performed for the suggested ESS. - Abstract: In this paper, the stationary super-capacitors are used to store a metro network regenerative braking energy. In order to estimate the required energy storage systems (ESSs), line 3 of Tehran metro network is modeled through a novel approach, in peak and off-peak conditions based on the real data obtained from Tehran metro office. A useful method is proposed to predict the maximum instantaneous regenerative energy which is delivered to each station before applying ESS and based on that the ESS configuration for each station is determined. Finally, the effectiveness of the proposed ESS is confirmed by economic evaluations and benefit/cost analyses on line 3 of Tehran metro network.

    MetroFission project has been looking at solving metrological problems related to a new generation of NPPs. The proposed Gen. IV NPPs are designed to run safely, make efficient use of natural resources, minimize the waste and maintain proliferation resistance. In order to reach these goals, the reactor operation involves higher temperatures, high-energy neutron fluence, different types of fuel where the minor actinides are included etc. The work has focused on improved temperature measurements, investigation of thermal properties of advanced materials, determination of new and relevant nuclear data and development of measurement techniques for radionuclides suitable for Gen. IV NPPs. The improved temperature measurement for nuclear power plant applications includes the development of a new Fe-C fixed point. Robust, repeatable and versatile cells have been constructed and compared with success among the project participants and their melting temperatures have been determined. Methodology of self-validating thermocouples has proven efficient at several fixed point temperatures using different designs. A practical acoustic thermometer has been tested at 1000 deg. C with success thanks to the use of innovative signal processing methods. Mo/Nb thermocouples have been obtained with different sheath materials and tested with the aim to achieve for the first time a reference function determined with the best possible uncertainties. Following reviews of designs and technology proposed for fourth generation nuclear plants effort within this project, with regards to thermal properties of advanced materials for nuclear design, has concentrated on provision of thermodynamic data to support the development of the sodium cooled fast reactor. Data has been critically assessed to represent the potential interaction between the Na coolant and the nuclear fuel taken to be based on (U, Pu)O 2 but incorporating minor actinides such as Np and Am.

No entanto, quando se trata da obtenção da umidade relativa a partir de termopar, o processo se torna mais cauteloso devido a outros fatores envolvidos. Neste estudo, avaliaram-se dois conjuntos psicrômetros de termopar, aspirado e não aspirado, em relação a um conjunto Vaisala, no período de 17 a 31/01/2008 (15 dias. A partir de medidas de temperaturas de bulbos seco e úmido foram obtidas medidas da umidade relativa, e com isso, foi possível compará-las com as medidas obtidas pelo conjunto Vaisala. Os dois tipos de psicrômetros apresentaram precisão e exatidão nas medidas de temperatura do ar, e apenas precisão nas medidas de umidade relativa do ar, sendo que o psicrômetro aspirado foi o mais preciso. Apesar do psicrômetro não aspirado ter apresentado menor precisão nas medidas, ele é mais robusto porque independe do micro-ventilador de 12 VDC, o que faz dele um sensor com menos riscos de medidas inadequadas. Ambos os psicrômetros, aspirado e não aspirado, não medem com exatidão a umidade relativa do ar no período noturno.

    Mexico City is one of the fastest subsiding metropolis in the world. At displacement rates ranging from 0 to -380 [mm/yr], the complex geological setting is subjected to differential subsidence, which has led to damage, operation interruptions, and accidents to the Collective Transport System, or Metro. The Metro plays a critical role in Mexico City, carrying more than four million passengers per day. However, no previous study has focused on the deformation monitoring along the 93 km of the Metro surface railways, mainly because of the limitations of the traditional geodetic techniques. In this study, we use high-resolution Interferometric Synthetic Aperture Radar (InSAR) observations to monitor land subsidence throughout the city and quantify differential subsidence along surface Metro lines. Our analysis is based on 34 TerraSAR-X StripMap scenes acquired from May 2011 to June 2013 and 36 COSMO-SkyMed Stripmap scenes acquired from June 2011 to June 2012. The data were processed using the StaMPS InSAR time series technique, obtaining point densities of up to 4827 points/km2. Our post-processing methodologies include the following two components: (1) Detection of differential subsidence along the metro lines by calculating subsidence gradients, and (2) Detection of apparent uplift—areas subsiding slower than their surroundings—by using spatial frequency filtering. The two analyses allow us to recognize four main consequences of differential subsidence in the Metro system: 1. Deflection in elevated railways, 2. Deflection in street-level railways, 3. Columns with decreased loading capacity, and 4. Apparent uplift affecting surrounding infrastructure. Our results aim at shortening the large gap between scientific geodetic studies and applicable engineering parameters that can be used by local authorities in the city for maintenance and new lines development.

    Full Text Available Suitable selection of the emergency alternatives is a critical issue in emergency response system of Unattended Train Operation (UTO metro system of China. However, there is no available method for dispatcher group in Operating Control Center (OCC to evaluate the decision under emergency situation. It was found that the emergency decision making in UTO metro system is relative with the preferences and the importance of multi-dispatcher in emergency. Regarding these factors, this paper presents a hybrid method to determinate the priority weights of emergency alternatives, which aggregates the preference matrix by constructing the emergency response task model based on the Weighted Ordered Weighted Averaging (WOWA operator. This calculation approach derives the importance weights depending on the dispatcher emergency tasks and integrates it into the Ordered Weighted Averaging (OWA operator weights based on a fuzzy membership relation. A case from train fire is given to demonstrate the feasibility and practicability of the proposed methods for Group Multi-Criteria Decision Making (GMCDM in emergency management of UTO metro system. The innovation of this research is paving the way for a systematic emergency decision-making solution which connects the automatic metro emergency response system with the GMCDM theory.

This paper presents an assessment of the risk due to metro line construction to groundwater in Jinan City using Analytic Hierarchy Process (AHP and Geographic International System (GIS. Based on the characteristics of hydrogeology and engineering geology, the assessment model is established from the perspectives of surface index and underground index. The assessment results show that the high and very high risk levels of surface index exceed 98% in the north region; and high and very high risk levels of underground index exceed 56% in urban center and southern region. The assessment result also shows that about 14% of the urban area belongs to very high risk level; regions of high risk are 20% in urban area, 9% in Changqing County and 43% in Pingyin County. In the high risk region, metro lines R1 to R3, which are under construction, and metro lines L1 to L5, which are planned, have very high and high risk. Therefore, risk control measures are proposed to protect the groundwater seepage path to spring.

    Full Text Available La longitud de rugosidad es un parámetro de escala característico de la capa de superficie, utilizado en estudios micrometeorológicos, de contaminación urbana, de potencial eólico o en los modelos dinámicos de pronóstico del tiempo y el clima. Experimentalmente este parámetro se determina a partir de datos observacionales del perfil de viento bajo condiciones neutrales de estabilidad atmosférica. Sin embargo, existen evidencias de una dependencia del mismo con los cambios en la estabilidad. Utilizando datos observados sobre una superficie con cobertura vegetal y bajo las hipótesis de la teoría de la semejanza de Monin-Obukhov, se estudió la variabilidad del parámetro de rugosidad con la estabilidad atmosférica. Se obtuvieron expresiones empíricas que permitieron estimar esa longitud en función de un parámetro de estabilidad. Se encontraron variaciones en su magnitud de hasta dos órdenes bajo condiciones estables, mientras que en condiciones inestables su variabilidad fue pequeña. Por otra parte, se estudió el impacto que producen las parametrizaciones obtenidas al aplicarlas en un preprocesador meteorológico para un modelo de difusión de contaminantes. Los resultados obtenidos tendrían un impacto directo en el campo de velocidades cercano a superficie

    To compare with the 2G mobile communication, 3G technologies can supply the perfect service scope and performance. 3G is the trend of the mobile communication. So now to build the transmission network, it is needed to consider how the transmission network to support the 3G applications. For the 3G network architecture, it include the 2 part: Utran access network and core network. So the metro optical network should consider how to build the network to adapt the 3G applications. Include the metro core and access layer. In the metro core, we should consider the network should evolved towards the Mesh architecture with ASON function to realize the fast protection and restoration, quick end-to-end service provision, and high capacity cross-connect matrix etc. In the access layer, the network should have the ability to access the 3G services such as ATM interface with IMA function. In addition, the traffic grooming should be provided to improve the bandwidth utility. In this paper, first we present the MCC network situation, the network planning model will be introduced. Then we present the topology architecture, node capacity and traffic forecast. At last, based on our analysis, we will give a total solution to MCC to build their metro optical network toward to the mesh network with the consideration of 3G services.

    Optical coherence tomography (OCT), as an interferometric method, has been studied as a distance ranger. As a technology capable of producing high-resolution, depth-resolved images of biological tissue, OCT had been widely used for the application of ophthalmology and has been commercialized in the market today. Enlightened by the emerging research interest in biomedical domain, the applications of OCT in industrial inspection were rejuvenated by a few groups to explore its potential for characterizing new materials, imaging or inspecting industrial parts as a service solution[3]. Benefiting from novel photonics components and devices, the industrial application of the older concepts in OCT can be re-visited with respect to the unique performance and availability. Commercial OCT developers such as Michelson Diagnostics (MDL; Orpington, U.K.) and Thorlabs (Newton, NJ) are actively exploring the application of OCT to industrial applications and they have outlined meaningful path toward the metrology application in emerging industry[3]. In this chapter, we will introduce the fundamental concepts of OCT and discuss its current and potential industrial applications.

    Older motorcyclists are under-recognised as vulnerable road users. Using Irish data from the Central Statistics Office, the Road Safety Authority and the Healthcare Pricing Office, we explored the trend of ageing riders and factors in older motorcyclist collisions and injuries. In 2005, 17 motorcyclists ≥55 were injured compared to 31 in 2012. Motorcyclists aged between 30 and 49 years and ≥50 have longer lengths of stay compared to riders <30. The percentage of motorcycles with an engine capacity of ≥750cc increased from 39.6% in 2007 to 46.7% in 2015. Older motorcyclists are less likely to be fatally injured in single vehicle collisions. Older motorcyclists are generally safer than younger riders but the proportion of older motorcyclist injury is rising. Irish road safety strategies and trauma services need to incorporate these findings into planning and development of preventive and treatment approaches

    Full Text Available The general focus of the study was to investigate the impact of advertisement on alcoholic beverage consumption at Bantama Sub-Metro in Kumasi. Objectives were to analyse the nature of advertisement of alcoholic beverages, determine factors that influence the consumption of alcoholic beverages and to examine the influence of advertisement on the consumption of alcoholic beverages. A convenient sampling, which is a non-probability sampling, was used to select 220 respondents for the study. Instruments used to collect data were questionnaires. Regression analysis was used to establish the relationship between advertisement and alcohol consumption, which indicated a highly positive correlation. It was revealed that electronic medium was the biggest vehicle through which adverts of alcoholic beverages reach consumers. Again, consumers were more attracted to adverts that made bare the product functions or performances and musicians made the highest impact on consumption patterns of consumers among the celebrities used in adverts of alcoholic beverages among others. The alcohol brewing industries in order to assert themselves well and widen the scope of their products to their target consumers should endeavour to sponsor public events.

  9. The Philippine electricity sector reform and the urban question: How metro Manila's utility is tackling urban poverty

    International Nuclear Information System (INIS)

    Mouton, Morgan

    2015-01-01

    In the early 2000s, the Philippine government reformed its electricity sector following neoliberal principles: unbundling of the power industry, privatisation of assets and commodification of electricity. This paper shows that the reform was primarily driven by the need to secure electricity supply and cut down tariffs. These national objectives ousted other issues, and notably those that find their expression at the urban level, among which the question of access to electricity in Metro Manila's urban poor communities. The central state withdrew its attention from the issue of electrification, and local actors had to react as they were confronted to social tensions and practices of pilferage. As a consequence, city governments and local administrations are getting involved in this issue, which opens the way to participation of civil society. This paper shows how the “rolling back” of the central state led to new partnerships and arrangements between the distribution utility, local governments and community organisations. This movement points to an urbanisation of energy issues, which could bring positive results for end-users provided that it is accompanied by a clearer regulatory framework. - Highlights: • The electricity reform did not take the urban poor into consideration. • The state retreated from issues of electrification. • Decentralisation favoured the emergence of new, local actors for this aspect of energy policy. • The distribution utility is left with an increased power over issues of access to electricity. • Territorially and qualitatively, electrification programs are more diverse

    2018-01-01

    Full Text Available Smart card data provide valuable insights and massive samples for enhancing the understanding of transfer behavior between metro and public bicycle. However, smart cards for metro and public bicycle are often issued and managed by independent companies and this results in the same commuter having different identity tags in the metro and public bicycle smart card systems. The primary objective of this study is to develop a data fusion methodology for matching metro and public bicycle smart cards for the same commuter using historical smart card data. A novel method with association rules to match the data derived from the two systems is proposed and validation was performed. The results showed that our proposed method successfully matched 573 pairs of smart cards with an accuracy of 100%. We also validated the association rules method through visualization of individual metro and public bicycle trips. Based on the matched cards, interesting findings of metro-bicycle transfer have been derived, including the spatial pattern of the public bicycle as first/last mile solution as well as the duration of a metro trip chain.

  11. Inferring Social Functions Available in the Metro Station Area from Passengers’ Staying Activities in Smart Card Data

    2017-12-01

    Full Text Available The function of a metro station area is vital for city planners to consider when establishing a context-aware Transit-Oriented Development policy around the station area. However, the functions of metro station areas are hard to infer using the static land use distribution and other traditional survey datasets. In this paper, we propose a method to infer the functions occurring around the metro station catchment areas according to the patterns of staying activities derived from smart card data. We first define the staying activities by the spatial and temporal constraints of the two consecutive alighting and boarding records from the individual travel profile. Then we cluster and label the whole staying activities by considering the features of duration, frequency, and start time. By analyzing the percentage of different types of aggregated activities happening around each metro station, we cluster and explore the functions of the metro station area. Taking Wuhan as a case study, we analyze the results of Wuhan metro systems and discuss the similarities and differences between the functions and the land use distribution around the station area. The results show that although there exist some agreements, there is also a gap between the human activities and the land uses around the station area. These findings could give us deeper insight into how people act around the stations by metro systems, which will ultimately benefit the urban planning and policy development.

    The thermal environment parameters, like the temperature and air velocity, are measured to investigate the heat comfort status of metro staff working area in winter in Qingdao. The temperature is affected obviously by the piston wind from the train and waiting hall in the lower Hall, and the temperature is not satisfied with the least heat comfort temperature of 16 °C. At the same time, the heat produced by the electrical and control equipments is brought by the cooling air to atmosphere for the equipment safety.

    In connection with the extension of the Copenhagen Metro system, architects and wireless operators met early in the design phase to plan the radio coverage inside the public areas of the metro transport system. Based on common best practice, an initial design for the antenna installations......, and hence radio coverage, was proposed for a distributed antenna system in each of two distinctly different types of underground stations. In this paper, we describe the considerations for the design, and specifically the modelling and analysis of the underground stations by way of a commercial ray......-tracing tool. Radio coverage results are given for different designs, including different number and types of antennas, their configuration and placement, as well as the dependency on frequency and construction materials and presence of trains on the station platforms.

Para simplificar el ajuste de esta función de densidad de probabilidad (fdp se supone que el parámetro de localización (θ es cero en híbridos de Populus; sin embargo, en algunos casos esta simplificación no asegura el mejor ajuste de la fdp, incidiendo en la representación de la estructura horizontal de los híbridos. El objetivo de la investigación fue calcular el parámetro θ que proporcione el mejor ajuste de la fdp lognormal del DAP en los híbridos I-488 e I-63/51. Para este cálculo se utilizó un algoritmo de búsqueda binaria, que minimizó el estadístico Dn de la prueba de Kolmogorov-Smirnov. 38 % de las parcelas presentó un parámetro θ distinto de cero, originando una mejoría del valor de probabilidad (P entre 0.02 y 55.4 %. Se hizo un análisis de varianza no paramétrico de la variable “√n * Dn”, ya que la variable original y múltiples transformaciones no permitieron aceptar los supuestos del análisis paramétrico. El tipo de ajuste presentó diferencias estadísticas altamente significativas con un valor de 17.1 (P0.800 y las edades un valor de 11.2 (P>0.260.

    Full Text Available Metro systems act as fast and efficient transport systems for many modern metropolises; however, enhancing higher usage of such systems often conflicts with providing suitable accessibility options. The traditional approach of metro accessibility studies seems to be an ineffective measure to gage sustainable access in which the equal rights of all users are taken into account. Bangkok Metropolitan Region (BMR transportation has increasingly relied on the role of two mass rapid transport systems publicly called “BTS Skytrain” and “MRT Subway”, due to limited availability of land and massive road congestion; however, access to such transit arguably treats some vulnerable groups, especially women, the elderly and disabled people unfairly. This study constructs a multi-dimensional assessment of accessibility considerations to scrutinize how user groups access metro services based on BMR empirical case. 600 individual passengers at various stations were asked to rate the questionnaire that simultaneously considers accessibility aspects of spatial, feeder connectivity, temporal, comfort/safety, psychosocial and other dimensions. It was interestingly found by user disaggregated accessibility model that the lower the accessibility perceptions—related uncomfortable and unsafe environment conditions, the greater the equitable access to services, as illustrated by MRT — Hua Lumphong and MRT — Petchaburi stations. The study suggests that, to balance the access priorities of groups on services, policy actions should emphasize acceptably safe access for individuals, cost efficient feeder services connecting the metro lines, socioeconomic influences and time allocation. Insightful discussions on integrated approach balancing different dimensions of accessibility and recommendations would contribute to accessibility-based knowledge and potential propensity to use the public transits towards transport sustainability.

    Metro Manila is ranked as one of the world's most polluted cities where air quality levels are 2-3 times higher than the levels set by WHO. Development of diseases could be alleviated if early warning signs as occurrence of gene mutations are detected early enough. The adapted hypoxanthine guanine phosphoribosyl transferase (HGPRT) mutation assay measures the degree of mutation on the HGPRT gene and allows rapid evaluation of the occurrence of mutation in an individual exposed to radiation or mutagens within six months after exposure. The objective of the project is to (1) assay exposure of Metro Manila residents exposed to environmental pollution, (2) determine population groups significantly affected by pollutants and (3) construct an environmental baseline HGPRT mutation data bank specific to area in Metro Manila. A composite table of personal information of donors against mutation index in two barangays in Venezuela is presented. About 30% of the total samples are shown to have mutation index greater than 0.5. So far, the data show a slightly higher mutation rate among donors who are smokers with more than 5 hours outdoor exposure to pollutants per day than the corresponding class of non-smokers.

    Full Text Available With the development of cities and the explosion of information, vast amounts of geo-tagged textural data about Points of Interests (POIs have been generated. Extracting useful information and discovering text spatial distributions from the data are challenging and meaningful. Also, the huge numbers of POIs in modern cities make it important to have efficient approaches to retrieve and choose a destination. This paper provides a visual design combing metro map and wordles to meet the needs. In this visualization, metro lines serve as the divider lines splitting the city into several subareas and the boundaries to constrain wordles within each subarea. The wordles are generated from keywords extracted from the text about POIs (including reviews, descriptions, etc. and embedded into the subareas based on their geographical locations. By generating intuitive results and providing an interactive visualization to support exploring text distribution patterns, our strategy can guide the users to explore urban spatial characteristics and retrieve a location efficiently. Finally, we implement a visual analysis of the restaurants data in Shanghai, China as a case study to evaluate our strategy.

    Full Text Available Skip-stop operation is a low cost approach to improving the efficiency of metro operation and passenger travel experience. This paper proposes a novel method to optimize the skip-stop scheme for bidirectional metro lines so that the average passenger travel time can be minimized. Different from the conventional “A/B” scheme, the proposed Flexible Skip-Stop Scheme (FSSS can better accommodate spatially and temporally varied passenger demand. A genetic algorithm (GA based approach is then developed to efficiently search for the optimal solution. A case study is conducted based on a real world bidirectional metro line in Shenzhen, China, using the time-dependent passenger demand extracted from smart card data. It is found that the optimized skip-stop operation is able to reduce the average passenger travel time and transit agencies may benefit from this scheme due to energy and operational cost savings. Analyses are made to evaluate the effects of that fact that certain number of passengers fail to board the right train (due to skip operation. Results show that FSSS always outperforms the all-stop scheme even when most passengers of the skipped OD pairs are confused and cannot get on the right train.

    Full Text Available In recent years, architectures, devices, and components in telecommunication networks have been challenged by evolutionary and revolutionary factors which are drastically changing the traffic features. Most of these changes imply the need for major re-configurability and programmability not only in data-centers and core networks, but also in the metro-access segment. In a wide variety of contexts, this necessity has been addressed by the proposed introduction of the innovative paradigm of software-defined networks (SDNs. Several solutions inspired by the SDN model have been recently proposed also for metro and access networks, where the adoption of a new generation of software-defined reconfigurable integrated photonic devices is highly desirable. In this paper, we review the possible future application scenarios for software-defined metro and access networks and software-defined photonics (SDP, on the base of analytics, statistics, and surveys. This work describes the reasons underpinning the presented radical change of paradigm and summarizes the most significant solutions proposed in literature, with a specific emphasis to physical-layer reconfigurable networks and a focus on both architectures and devices.

    Considering that metro network expansion brings us with more alternative routes, it is attractive to integrate the impacts of routes set and the interdependency among alternative routes on route choice probability into route choice modeling. Therefore, the formulation, estimation and application of a constrained multinomial probit (CMNP) route choice model in the metro network are carried out in this paper. The utility function is formulated as three components: the compensatory component is a function of influencing factors; the non-compensatory component measures the impacts of routes set on utility; following a multivariate normal distribution, the covariance of error component is structured into three parts, representing the correlation among routes, the transfer variance of route, and the unobserved variance respectively. Considering multidimensional integrals of the multivariate normal probability density function, the CMNP model is rewritten as Hierarchical Bayes formula and M-H sampling algorithm based Monte Carlo Markov Chain approach is constructed to estimate all parameters. Based on Guangzhou Metro data, reliable estimation results are gained. Furthermore, the proposed CMNP model also shows a good forecasting performance for the route choice probabilities calculation and a good application performance for transfer flow volume prediction.

  19. Capitalización anticipada del metro de Santiago en el precio de las viviendas

    Directory of Open Access Journals (Sweden)

    Claudio Agostini

    2008-01-01

    Full Text Available En general, las viviendas que por su ubicación muestran mejores accesos tienen un valor de mercado superior respecto a viviendas de características similares con peores accesos. Esta diferencia se debe a los menores costos de transporte hacia los principales mercados laborales y comerciales de una ciudad. Por esta razón, las inversiones en infraestructura pública de transporte, como por ejemplo la construcción de una nueva línea de metro, se capitalizan total o parcialmente en el precio de los terrenos y de las viviendas. Este trabajo estudia empíricamente el grado de capitalización en el precio de las viviendas que tuvo la construcción de la nueva línea 4 del metro en la ciudad de Santiago. En particular, dado que la nueva línea entra en operación en diciembre de 2005, se estima el grado de capitalización anticipada en el precio de las viviendas ocurrido en el momento del anuncio de la construcción de la nueva línea 4 y en el momento del anuncio de la ingeniería básica que determinó la ubicación de las estaciones. Con una base de datos única, que contiene todas las transacciones de compra y venta de viviendas realizadas en el Gran Santiago entre Diciembre de 2000 y Marzo de 2004. Los resultados muestran que el valor promedio de los departamentos aumentó entre 3.3% y 4.4% en consecuencia del anuncio de construcción y entre 4.5% y 5.7% después del conocimiento de la ubicación de las estaciones. Este aumento no se distribuye en forma uniforme, sino que depende de la distancia a la estación de metro más cercana. Un efecto indirecto de esta capitalización es que la recaudación del impuesto a las propiedades aumentaría si se reavalúan las propiedades de acuerdo a su aumento de valor. Este efecto no es despreciable en magnitud y podría representar al menos entre 14 y 20% de la inversión de la nueva línea de metro, lo cual abre una discusión interesante respecto a la forma de financiar la expansión de la red de metro.

    Full Text Available Purpose. The analysis of the existing studies showed that the increasing of energy efficiency of metro rolling stock becomes especially important and requires timely solutions. It is known that the implementation of regenerative braking systems on rolling stock will allow significantly solving this problem. It was proved that one of the key issues regarding the introduction of the above-mentioned systems is research on efficient use of electric energy of regenerative braking. The purpose of the work is to evaluate the amount of excessive electric power of regenerative braking under normal operation conditions of the rolling stock with regenerative braking systems for the analysis of the energy saving reserves. Methodology. Quantifiable values of electrical energy consumed for traction, returned to the contact line and dissipated in braking resistors (excessive energy are determined using results of experimental studies of energy exchange processes under normal operating conditions of metro rolling stock with regenerative systems. Statistical methods of data processing were applied as well. Findings. Results of the studies analysis of metro rolling stock operation under specified conditions in Sviatoshinsko-Brovarskaia line of KP «Kyiv Metro system» stipulate the following: 1 introduction of regenerative braking systems into the rolling stock allows to return about 17.9-23.2% of electrical energy consumed for traction to the contact line; 2 there are reserves for improving of energy efficiency of rolling stock with regenerative systems at the level of 20.2–29.9 % of electrical energy consumed for traction. Originality. For the first time, it is proved that the most significant factor that influences the quantifiable values of the electrical energy regeneration is a track profile. It is suggested to use coefficients which indicate the amount and reserves of unused (excessive electrical energy for quantitative evaluation. Studies on

    Full Text Available Ao calcular o diâmetro médio ponderado (DMP ou o diâmetro médio geométrico (DMG de uma amostra de solo, ponderam-se o diâmetro médio aritmético (no caso do DMP ou o logarítmico (no caso do DMG de cada classe pela massa de agregados nela retida. A média aritmética de cada classe, multiplicada pela massa de agregados retidos na respectiva classe, apenas é correta, quando ocorrer uma distribuição simétrica de massa de agregados dentro de cada classe, o que é muito pouco provável. O objetivo deste trabalho, desenvolvido no final de 1996 no Departamento de Solos da UFRGS, Porto Alegre, é propor um novo método para o cálculo do diâmetro médio dos agregados, presumindo ser a distribuição dentro de cada classe semelhante à distribuição dos agregados de toda a amostra. Essa proposta pressupõe ser o diâmetro médio da classe mais bem estimado por aquele diâmetro que divide os agregados contidos nela em duas partes de massa igual. Para isso foi apresentado um procedimento de cálculo, e o diâmetro médio assim encontrado foi denominado "diâmetro médio ajustado" (DMA. Para testar o método, utilizaram-se dados existentes de vários solos, condições de manejo do solo e rotações de culturas. Considerando os resultados, justifica-se a utilização do parâmetro DMA no lugar do DMP ou DMG, por representar mais corretamente o diâmetro médio dos agregados de uma amostra de solo.

    Full Text Available No presente trabalho descreve-se um novo tipo de evaporímetro, cujo princípio de funcionamento está baseado em leis físicas que regem o fenômeno de tensão superficial. Neste tipo de evaporímetro a medida da evaporação é feita por processo volumétrieo, dispensando o emprego de mecanismos de precisão e dispendiosos. Foi feita uma análise matemática do princípio de funcionamento do novo evaporímetro, demonstrando-se oferecer exatidão plenamente satisfatória para propósitos práticos. São dados suficientes detalhes construtivos, de instalação e operação, a fim de permitir que pessoas e entidades interessadas possam reproduzi-lo e comprovar as vantagens de seu emprêgo.In this paper is described a new type of evaporimeter, the principle of operation of which is based on physical laws governing the surface tension phenomenon. The measurement of evaporation in, the new evaporimeter, described as Evaporimeter IA-58, is made by simple volumetric procedure, thus avoiding the use of precise and expensive mechanisms. A mathematical analysis of the principle of operation is made, and proves that the new evaporimeter can offer satisfactory xeaults for practical use. The operation of the new evaporimeter is very simple, since only volumetric measurements are made, with a graduated cylinder of 1000 ml, both of the added water to restore the water level to the same initial level and the outflown or excess water. It is believed that enough details are given to allow the understanding of the construction, installation and operation of the new evaporimeter, bo that interested persons or organizations could have the model reproduced and verify the advantage of its use.

    Full Text Available As mãos de três trabalhadores foram irradiadas acidentalmente numa indústria em Camaçari, Estado da Bahia, Brasil. O diagnóstico clínico de radiodermite aguda foi possível, antes mesmo da confirmação dosimétrica da ocorrência, em virtude das manifestações cutâneas exibidas, precedidas por um eritema, e também pelas histórias ocupacionais. As avaliações das doses recebidas pelos acidentados, usando-se restituições com dosímetros termoluminescentes, tiveram boa correlação com as doses estimadas em função das manifestações clínicas. A causa imediata do acidente foi a má manutenção do equipamento que levou a sua janela posterior a ficar permanentemente aberta, porém foram fatores contributórios importantes a falta de informação dos empregados sobre os possíveis efeitos biológicos das radiações ionizantes e o não seguimento dos procedimentos operacionais corretos. A descrição deste acidente é importante, face ao grande número de difratômetros existentes em laboratórios, universidades, centros de pesquisa e indústrias. Tais aparelhos são considerados "virtualmente isentos de risco ocupacional", o que não é verdadeiro, como comprova a ocorrência que descrevemos. A evolução médica dos pacientes tem sido satisfatória, especialmente em virtude da baixa energia do feixe de raios X do difratômetro e, em conseqüência, da sua pequena penetração tissular.

  11. CALIBRAÇÃO DE ERROS SISTEMÁTICOS EM ACELERÔMETROS MEMS

    Directory of Open Access Journals (Sweden)

    Stefanie Von Randow de Souza

    Full Text Available Os sensores inerciais MEMS de baixo custo apresentam grandes vantagens para diversas aplicações em navegação, porém estes dispositivos são caracterizados por diversos tipos de erros. Através de procedimentos específicos como a calibração é possível obter resultados com melhor acurácia. Neste artigo utilizou-se o Método de Calibração Multi-Posições Modificado, que permite determinar erros sistemáticos, tais como deriva, erro de fator de escala e de não-ortogonalidade. O método, o procedimento e as equações desta calibração são brevemente descritos. Primeiramente foi realizada a calibração com diferentes acelerômetros. O desempenho dos parâmetros de calibração foi verificado por meio de um teste em campo, comparando as trajetórias calculadas pelas acelerações antes e após as correções. Após a correção das acelerações com os parâmetros de calibração, foram verificadas algumas discrepâncias nas trajetórias. Ainda assim houve uma melhora significativa na solução final. A vantagem deste método consiste no fato de que este não requer o uso de equipamentos especiais ou de um preciso alinhamento dos sensores, podendo ser aplicado em campo antes da utilização dos sensores.

  12. Radiofrequency electromagnetic radiation exposure inside the metro tube infrastructure in Warszawa.

    2015-09-01

    Antennas from various wireless communications systems [e.g. mobile phones base transceiver stations (BTS) and handsets used by passengers, public Internet access, staff radiophone transmitters used between engine-drivers and traffic operators] emitting radiofrequency electromagnetic radiation (RF-EMR) are used inside underground metro public transportation. Frequency-selective exposimetric investigations of RF-EMR exposure inside the metro infrastructure in Warsaw (inside metro cars passing between stations and on platforms) were performed. The statistical parameters of exposure to the E-field were analyzed for each frequency range and for a total value (representing the wide-band result of measurements of complex exposure). The recorded exposimetric profiles showed the dominant RF-EMR sources: handsets and BTS of mobile communication systems (GSM 900 and UMTS 2100) and local wireless Internet access (WiFi 2G). Investigations showed that the GSM 900 system is the dominant source of exposure - BTS (incessantly active) on platforms, and handsets - used by passengers present nearby during the tube drive. The recorded E-field varies between sources (for BTS were: medians - 0.22 V/m and 75th percentile - 0.37 V/m; and for handsets: medians - 0.28 V/m and 75th percentile - 0.47 V/m). Maximum levels (peaks) of exposure recorded from mobile handsets exceeded 10 V/m (upper limit of used exposimeters). Broadband measurements of E-field, including the dominant signal emitted by staff radiophones (151 MHz), showed that the level of this exposure of engine-drivers does not exceed 2.5 V/m.

    The state of the global industrial garnet industry in 1999 is discussed. Industrial garnet mined in the U.S., which accounts for approximately one-third of the world's total, is usually a solid-solution of almandine and pyrope. The U.S. is the largest consumer of industrial garnet, using an estimated 47,800 st in 1999 as an abrasive and as a filtration medium in the petroleum industry, filtration plants, aircraft and motor vehicle manufacture, shipbuilding, wood furniture finishing operations, electronic component manufacture, ceramics manufacture, and glass production. Prices for crude concentrates ranged from approximately $50 to $110/st and refined garnet from $50 to $215/st in 1999, depending on type, source, quantity purchased, quality, and application.

    2011-01-01

    The purpose of this study was to see whether differences emerge between older whites, older blacks, and older Mexican Americans in 12 measures of prayer. These measures assess four dimensions of prayer: The social context of prayer, interpersonal aspects of prayer, beliefs about how prayer operates, and the content or focus of prayers. Data from two nationwide surveys of older adults suggest that with respect to all four dimensions, the prayer lives of older whites appear be less developed than the prayer lives of older blacks and older Mexican Americans. In contrast, relatively few differences were found in the prayer lives of older African Americans and older Mexican Americans. The theoretical implications of these findings are discussed.

    2012-06-01

    Full Text Available From an environmental perspective, the underground metro system is one of the cleanest forms of public transportation in urban agglomerations. Current studies report contradicting results regarding air quality in the metro systems: whereas some reveal poor air quality, others report PM levels which are lower or of the same order of magnitude than those measured in traffic sites above ground level. The present work assesses summer and winter indoor air quality and passenger exposure in the Barcelona metro, focusing on PM levels and their metal contents. In addition, the impact on indoor air quality of platform screen door systems (automated systems consisting of closed rail track and platforms is evaluated, to determine whether these systems reduce passenger exposure to PM when compared with conventional systems (open tracks and platforms. In the Barcelona metro PM levels inside the trains in summer are amongst the lowest reported for worldwide metro systems (11–32 μg m−3 PM2.5. This is most likely due to the air conditioning system working in all carriages of the Barcelona metro during the whole year. Levels were considerably higher on the platforms, reaching mean levels of 46 and 125 μg m3 in the new (L9 and old (L3 lines, respectively. PM10 data are also reported in the present study, but comparison with other metro systems is difficult due to the scarcity of data compared with PM2.5. Results showed distinct PM daily cycles, with a drastic increase from 06:00 to 07:00 a.m., a diurnal maximum from 07:00 to 10:00 p.m., and marked decrease between 10:00 p.m. and 05:00 a.m. The elements with the highest enrichment were those associated with wheel or brake abrasion products (Ba, Fe, Cu, Mn, Cr, Sb, As, Mo, Co, Sr, among others. Laminar hematite (Fe2O3 was the dominant particle type, being mainly originated by mechanical abrasion of the rail track and wheels.

    Jin, Fanglei; Zhang, Yongsheng; Liu, Shasha

    2017-01-01

    With the rapid development of the Metro network in China, the greatly increased route alternatives make passengers’ route choice behavior and passenger flow assignment more complicated, which presents challenges to the operation management. In this paper, a path sized logit model is adopted to analyze passengers’ route choice preferences considering such parameters as in-vehicle time, number of transfers, and transfer time. Moreover, the “perceived transfer threshold” is defined and included in the utility function to reflect the penalty difference caused by transfer time on passengers’ perceived utility under various numbers of transfers. Next, based on the revealed preference data collected in the Guangzhou Metro, the proposed model is calibrated. The appropriate perceived transfer threshold value and the route choice preferences are analyzed. Finally, the model is applied to a personalized route planning case to demonstrate the engineering practicability of route choice behavior analysis. The results show that the introduction of the perceived transfer threshold is helpful to improve the model’s explanatory abilities. In addition, personalized route planning based on route choice preferences can meet passengers’ diversified travel demands. PMID:28957376

    Full Text Available Urban population in Indian cities is encouraging auto reliance and having unsafe economic, social and environmental consequences. Land-use-change patterns are the outcome of the complex relations between the human and the physical surroundings. To address these issues the planners are moving beyond land use planning to a sustainable development. Transit and Land use planning are important components to achieve sustainable future of urban development. TOD is a planning tool to encourage this integration. This paper discusses the land use scenario and opportunity around four Metro transit stations in Faridabad city. Different methods and various sets of indicators are considered to evaluate and measure TOD index in this study. This study will evaluate and measure the Faridabad city in the context of land use around Metro Stations to support TOD. This paper seeks to answer how to promote walkable communities, compact and transit-oriented development (TOD that incorporates mixed land use development, including neighbourhood schools, retail and business related space and a mix range of housing types within walkable distance. This paper concludes that the stations area which had a low TOD score needs to have policy for improvement. If planned efficiently, TODs can realize the sustainable development with considerable change in the urban development that focuses on pedestrian based neighbourhood planning.

    Chennai metropolis has been growing rapidly. Need was felt of a metro rail system. Two corridors were planned. Corridor 1, of 23 km starting from Washermanpet to Airport. 14.3 km of this would be underground. Corridor 2, of 22 km starting from Chennai Central Railway station to St. Thomas Mount. 9.7 km of this would be underground. Occupational health centre's role involved selection of miners and assessing their fitness to work under compressed air. Planning and execution of compression and decompression, health monitoring and treatment of compression related illnesses. More than thirty five thousand man hours of work was carried out under compressed air pressure ranged from 1.2 to 1.9 bar absolute. There were only three cases of pain only ( Type I) decompression sickness which were treated with recompression. Vigilant medical supervision, experienced lock operators and reduced working hours under pressure because of inclement environmental conditions viz. high temperature and humidity, has helped achieve this low incident. Tunnelling activity will increase in India as more cities will soon opt for underground metro railway. Indian standard IS 4138 - 1977 " Safety code for working in compressed air" needs to be updated urgently keeping pace with modern working methods.

    Full Text Available El crecimiento de población y empleo en la metrópoli de Madrid implica un aumento de la movilidad y de su complejidad. Este trabajo analiza cómo influye esta situación en el planeamiento de los transportes públicos del gobierno de Madrid, cuyo principal esfuerzo inversor se ha centrado desde 1999 en la ampliación de la red de Metro hacia los municipios que rodean la ciudad. El análisis de la eficiencia de estas ampliaciones ofrece los siguientes resultados: i el menor coste de la inversión de metro ligero ha permitido reducir los problemas financieros de los gobiernos madrileños; y ii la demanda por los nuevos servicios de transporte aumenta durante los primeros años, aunque desciende posteriormente. Estas conclusiones sugieren la complejidad de las decisiones económicas y políticas de estas ampliaciones, adaptadas a la evolución policéntrica y dispersa de Madrid.

    This paper addresses the topic of energy and development through a multi-disciplinary and systemic approach that combines environmental considerations with a social understanding of consumption. The focus is on electricity usage in the home and specifically lighting and cooling. Set in the urban mega-polis of Metro Manila, the Philippines, energy consumption is first placed in its biophysical perspective: the energy sources and electricity grid are presented, in relation to the Philippines as well as the region. The research findings then explore the social and cultural drivers behind household electricity consumption, revealing in several examples the strong influence of globalization-understood here as the flow of people, remittances, images and ideas. Policy recommendations are provided, based on the research results, with concluding remarks relevant to other similar contexts. - Research highlights: {yields}Metro Manila household electricity consumption is environmentally significant. {yields}The meaning given to electricity services varies by socio-economic group. {yields}Structural conditions, such as building type, can lock-in energy consumption. {yields}Global flows-people, ideas, remittances-influence local consumption patterns. {yields}Social networks, rather than the individual consumer, can influence change.

Although considerable attention has been paid to travel patterns, the relationship between travel patterns and the functional structure of a city is yet to be well understood. In this research, we study this relationship by analysing metro passenger trip data (in Beijing and Shenzhen in China and London in the United Kingdom), and we present two unprecedented findings. First, through averaging, a linear relationship is found to exist between individual travel distance and the distance between the origin and the city centre. The underlying mechanism is a travel pattern we call "ring aggregation", i.e., the daily movement of city passengers is aggregated into a ring (with approximately equal distances to the city centre). Then, for commuting trips, the daily travel pattern can be regarded as switching between the outer residential ring and the inner work ring. Second, this linear relationship and the ring aggregation pattern seem to be exclusive characteristics of metro systems (and may also fit other moderate- and long-distance transportation modes) but do not apply to short-distance transportation modes, such as bicycles and taxis. This finding implies that the ring aggregation pattern is a product of the relationship between travel patterns and the city functional structure at a large scope.

  1. Understanding household energy consumption patterns: When 'West Is Best' in Metro Manila

    This paper addresses the topic of energy and development through a multi-disciplinary and systemic approach that combines environmental considerations with a social understanding of consumption. The focus is on electricity usage in the home and specifically lighting and cooling. Set in the urban mega-polis of Metro Manila, the Philippines, energy consumption is first placed in its biophysical perspective: the energy sources and electricity grid are presented, in relation to the Philippines as well as the region. The research findings then explore the social and cultural drivers behind household electricity consumption, revealing in several examples the strong influence of globalization-understood here as the flow of people, remittances, images and ideas. Policy recommendations are provided, based on the research results, with concluding remarks relevant to other similar contexts. - Research highlights: →Metro Manila household electricity consumption is environmentally significant. →The meaning given to electricity services varies by socio-economic group. →Structural conditions, such as building type, can lock-in energy consumption. →Global flows-people, ideas, remittances-influence local consumption patterns. →Social networks, rather than the individual consumer, can influence change.

    Marketing has taken on increased importance in the United States' health care industry, especially with respect to Americans aged 55 and older. Given that health care costs account for 14 percent of the GNP of the U.S., and that older Americans represent nearly 25 percent of all health care expenditures, the ability of physicians to assess the perceptions of service quality, service value, and satisfaction and the effects of these variables on patient loyalty with respect to older patients is very important. A comprehensive model of patient behavior is introduced and tested. The results suggest the medical office staff and the expertise of the physician play particularly important roles in older patients' perceptions of service quality. In addition, strong relationships were found between (1) Service Quality and Satisfaction, (2) Satisfaction and Patient Behavior (repeated use of the physician), and (3) Service Quality and Patient Behavior. Conclusions and suggestions for future research are offered.

    Industrial gas companies have fought hard to boost sales and hold margins in the tough economic climate, and investments are well down from their 1989-'91 peak. But 'our industry is still very strong long term' says Alain Joly, CEO of industry leader L'Air Liquide (AL). By 1994, if a European and Japanese recovery follows through on one in the U.S., 'we could see major [investment] commitments starting again,' he says. 'Noncryogenic production technology is lowering the cost of gas-making possible new applications, oxygen is getting plenty of attention in the environmental area, and hydrogen also fits into the environmental thrust,' says Bob Lovett, executive v.p./gases and equipment with Air Products ampersand Chemicals (AP). Through the 1990's, 'Industrial gases could grow even faster than in the past decade,' he says. Virtually a new generation of new gases applications should become reality by the mid-1990s, says John Campbell, of industry consultants J.R. Campbell ampersand Associates (Lexington, MA). Big new oxygen volumes will be required for powder coal injection in blast furnaces-boosting a steel mill's requirement as much as 40% and coal gasification/combined cycle (CGCC). Increased oil refinery hydroprocessing needs promise hydrogen requirements

    RESUMEN

    El presente trabajo expone una visión general de los parámetros inerciales necesarios para el modelado biomecánico del cuerpo humano desde una perspectiva biomecánica, realizando un análisis retrospectivo, situación actual así como tendencias futuras en este ámbito. El modelado del cuerpo humano implica la determinación de una serie de puntos anatómicos y segmentos interconectados, que deben ser complementados con información inercial como es la masa segmentaria, el vector posición del centro de gravedad, los ejes de un sistema de referencia local segmentario, así como los momentos de inercia. La obtención de estos parámetros inerciales se considera imprescindible para el análisis biomecánico ya que permiten obtener algunas variables consideradas como básicas en cualquier análisis cuantitativo del movimiento, como son el centro de gravedad (CG tanto segmentario como corporal, el momento de inercia (I y el momento angular (H segmentario y corporal.

    ABSTRACT

    This work gives a general view of the inertial parameters needed for the biomechanical modelling of the human body from the biomechanical point of view, making an analysis of the past, present situations and future tendencies in this subject. Human body modelling needs to determine several anatomical points and interconnected segments, which should be complemented with inertial information such as the segmentary mass, centre of gravity position vector, axes of the local segmentary reference system, and also the moments of inertia. The process of obtaining this inertial parameters is essential for biomechanical analysis since it enables us to obtain several basic variables needed in any quantitative analysis of movement, for example

    Using the solid waste management programmes of three barangays (the smallest unit of local government in the Philippines) in Quezon City, Metro Manila, as a case study, this research aimed to further the development of efficient organic waste recycling systems through the promotion of urban agricultural activities on green and vacant spaces. First, the quantity of organic waste and compost produced through ongoing barangay projects was measured. The amount of compost that could potentially be utilized on farmland and vacant land within the barangays was then identified to determine the possibility of a local recycling system. The results indicate that, at present, securing buyers for compost is difficult and, therefore, most compost is distributed to large neighbouring farm villages. However, the present analysis of potential compost use within the barangay demonstrates that a more local compost recycling system is indeed feasible.

    Introduction of spatial division multiplexing (SDM) has added a new dimension in an effort to increase optical fiber channel capacity. At the same time, it can also be explored as an advanced optical networking tool. In this paper, we have investigated the resource allocation to end-users in multidimensional networking structure with plurality of spectral and spatial modes actively deployed in different networking segments. This presents a more comprehensive method as compared to the common practice where the segments of optical network are analyzed independently since the interaction between network hierarchies is included into consideration. We explored the possible transparency from the metro/core network to the optical access network, analyzed the potential bottlenecks from the network architecture perspective, and identified an optimized network structure. In our considerations, the viability of optical grooming through the entire hierarchical all-optical network is investigated by evaluating the effective utilization and spectral efficiency of the network architecture.

  4. A Fuzzy Logic-Based Approach for Estimation of Dwelling Times of Panama Metro Stations

    2015-04-01

    Full Text Available Passenger flow modeling and station dwelling time estimation are significant elements for railway mass transit planning, but system operators usually have limited information to model the passenger flow. In this paper, an artificial-intelligence technique known as fuzzy logic is applied for the estimation of the elements of the origin-destination matrix and the dwelling time of stations in a railway transport system. The fuzzy inference engine used in the algorithm is based in the principle of maximum entropy. The approach considers passengers’ preferences to assign a level of congestion in each car of the train in function of the properties of the station platforms. This approach is implemented to estimate the passenger flow and dwelling times of the recently opened Line 1 of the Panama Metro. The dwelling times obtained from the simulation are compared to real measurements to validate the approach.

    While the concept of Software Defined Networking (SDN) has seen a rapid deployment within the data center community, its adoption in telecommunications network has progressed slowly, although the concept has been swiftly adopted by all major telecoms vendors. This paper presents a control plane architecture for SDN-driven converged metro-access networks, developed through the DISCUS European FP7 project. The SDN-based controller architecture was developed in a testbed implementation targeting two main scenarios: fast feeder fiber protection over dual-homed Passive Optical Networks (PONs) and dynamic service provisioning over a multi-wavelength PON. Implementation details and results of the experiment carried out over the second scenario are reported in the paper, showing the potential of SDN in providing assured on-demand services to end-users.

    This paper presents the Time Shared Optical Network (TSON) as metro mesh network architecture for guaranteed, statistically-multiplexed services. TSON proposes a flexible and tunable time-wavelength assignment along with one-way tree-based reservation and node architecture. It delivers guaranteed sub-wavelength and multi-granular network services without wavelength conversion, time-slice interchange and optical buffering. Simulation results demonstrate high network utilization, fast service delivery, and low end-to-end delay on a contention-free sub-wavelength optical transport network. In addition, implementation complexity in terms of Layer 2 aggregation, grooming and optical switching has been evaluated. © 2011 Optical Society of America

    The emergence of cloud computing and big data has rapidly increased the deployment of small and mid-sized data centers. Enterprises and cloud providers require an agile network among these data centers to empower application reliability and flexible scalability. We present a software-defined inter data center network to enable on-demand scale out of data centers on a metro-scale optical network. The architecture consists of a combined space/wavelength switching platform and a Software-Defined Networking (SDN) control plane equipped with a wavelength and routing assignment module. It enables establishing transparent and bandwidth-selective connections from L2/L3 switches, on-demand. The architecture is evaluated in a testbed consisting of 3 data centers, 5-25 km apart. We successfully demonstrated end-to-end bulk data transfer and Virtual Machine (VM) migrations across data centers with less than 100 ms connection setup time and close to full link capacity utilization.

In order to ensure the safety and sustainable development of urban rail transit, the PS-InSAR technology with millimeter deformation measurement accuracy has been widely applied to monitor the deformation of urban rail transit. In this paper, 32 scenes of COSMO-SkyMed descending images and 23 scenes of Envisat ASAR images covering the Shanghai Metro Line 6 acquired from 2008 to 2010 are used to estimate the average deformation rate along line-of-sight (LOS direction by PS-InSAR method. The experimental results show that there are two main subsidence areas along the Shanghai Metro Line 6, which are located between Wuzhou Avenue Station to Wulian Road Station and West Gaoke Road Station to Gaoqing Road Station. Between Wuzhou Avenue Station and Wulian Road Station, the maximum displacement rate in the vertical direction of COSMO-SkyMed images is −9.92 mm/year, and the maximum displacement rate in the vertical direction of Envisat ASAR images is −8.53 mm/year. From the West Gaoke Road Station to the Gaoqing Road Station, the maximum displacement rate in the vertical direction of COSMO-SkyMed images is −15.53 mm/year, and the maximum displacement rate in the vertical direction of Envisat ASAR images is −17.9 mm/year. The results show that the ground deformation rates obtained by two SAR platforms with different wavelengths, different sensors and different incident angles have good consistence with each other, and also that of spirit leveling.

    Os aglomerados globulares são considerados laboratórios astrofísicos para a verificação da teoria de evolução estelar, bem como a trajetória químio-dinâmica das galáxias hospedeiras. Em particular, 47 Tucanae (NGC 104) configura-se como um dos mais extensivamente estudados aglomerados globulares da Galáxia devido a relativa proximidade ao Sol (R¤ = 4.5 kpc) e alta latitute galáctica (b = -44°,89). Neste trabalho, apresentamos a velocidade radial heliocêntrica e os parâmetros atmosféricos (Teff, logg, [Fe/H]) de 5 estrelas gigantes do aglomerado globular 47 Tucanae. Os espectros foram obtidos pelo espectrógrafo UVES (Ultaviolet Visual Echelle Spectrograph) de alta resolução (R = 60000) e alta razão sinal-ruído (S/N > 200), acoplado ao telescópio de 8,2m Kueyen do VLT (Very Large Telescope). Nós encontramos = -22,43 +/- 3,97 km/s, [Fe/H] ~ -0.7, 1,2 estrelas cobrem um intervalo de magnitude 12,2 < V < 14,2.

    Air Particulate matter (APM) is a mixture of different pollutant sources which can be of anthropogenic and/or natural origin, of which the size of great concern with regard to adverse effects on human health are generally less than 10μm (Referred to as PM10). Identification and apportionment of pollutant sources is important to be able to have better understanding of prevailing conditions in the area and thus better air quality management can be applied. APM (PM10) at sampling sites in Metro Manila (Philippines) has been monitored since 1998 for the primary purpose of source identification and source apportionment. APM samples (fractionated into coarse (PM2.5-10) and fine (PM2.5) fractions) were collected using a Gent air sampler. Particulate mass was determined by gravimetry and black carbon by reflectometry organic carbon/elemental carbon by thermal optical reflectance. Elemental concentrations were determined using nuclear and related analytical techniques such as the particle-induced x-ray emission (PIXE) spectrometry and x-ray fluorescence (XRF) spectrometry. Source apportionment of fine air particles was done using PMF2. Result show PM10 levels to be in compliance to the Philippine 1-year guideline value of 60 μg m“-“3 but in exceedance of the US EPA 1-year standard of 15 μg m“-“3 and the WHO 1-year guideline value of 10 μg m“-“3. Annual mean % Fine BC levels range from 33% to 59%, but individual points can reach up to more than 80% of the PM2.5 levels. Pb level in the fine fraction exhibit decreasing trend coinciding with the introduction of unleaded-gasoline starting in 1998 and the eventual phase-out of the use of leaded-gasoline in 2001. Six air pollution sources have been identified in the fine fraction with vehicular emissions making up the bulk at about 50%. Other sources are smoke, secondary S, fine soil and industry. Addressing problems regarding traffic-related activities can greatly reduce the fine particulate pollution problems

    This study examined whether perceived social support predicted adaptive personality change in older adulthood, focusing on the trait of conscientiousness. We tested this hypothesis both at the broad domain level and with respect to the specific lower order facets that comprise conscientiousness: order, self-control, industriousness, responsibility, and traditionalism. A sample of 143 older adults (aged 60-91) completed measures of conscientiousness and social support during 2 assessments 7 months apart. Social support and conscientiousness were positively correlated among older adults. Moreover, older adults who perceived greater social support at baseline were more likely to gain in conscientiousness over time. The magnitude of this effect was relatively similar across the order, self-control, and industriousness facets. Perceived social support provides multiple benefits later in life, and the current results add to this literature by showing that it also promotes conscientiousness. As conscientiousness is linked to a variety of positive outcomes later in life, including health, future research should examine whether conscientiousness change may be an important mechanism through which social support enhances resilience in older adulthood. © The Author 2013.

    Full Text Available The installation of stationary super-capacitor energy storage system (ESS in metro systems can recycle the vehicle braking energy and improve the pantograph voltage profile. This paper aims to optimize the energy management, location, and size of stationary super-capacitor ESSes simultaneously and obtain the best economic efficiency and voltage profile of metro systems. Firstly, the simulation platform of an urban rail power supply system, which includes trains and super-capacitor energy storage systems, is established. Then, two evaluation functions from the perspectives of economic efficiency and voltage drop compensation are put forward. Ultimately, a novel optimization method that combines genetic algorithms and a simulation platform of urban rail power supply system is proposed, which can obtain the best energy management strategy, location, and size for ESSes simultaneously. With actual parameters of a Chinese metro line applied in the simulation comparison, certain optimal scheme of ESSes’ energy management strategy, location, and size obtained by a novel optimization method can achieve much better performance of metro systems from the perspectives of two evaluation functions. The simulation result shows that with the increase of weight coefficient, the optimal energy management strategy, locations and size of ESSes appear certain regularities, and the best compromise between economic efficiency and voltage drop compensation can be obtained by a novel optimization method, which can provide a valuable reference to subway company.

    Directory of Open Access Journals (Sweden)

    2013-01-01

    Full Text Available Based on simulations of passenger transports of two representative types of metro trains in China, this study analyzes efficiencies of energy consumption and passenger transport of a metro train in the effect of its target speed, formation scale (FS (i.e., length and mass of the formation, relative traction capacity (RTC (i.e., ratio of the motoring cars to all its cars, and so forth. It is found that increasing energy cost efficiency of a metro train with decreasing its target speed is evidently accelerated with reducing its RTC below 0.50 at the expense of obviously lowering its passenger transport efficiency. Moreover, if the passenger capacity of the train is sufficiently utilized, increasing its FS for the same RTC is easy to have its passenger transport efficiency improved significantly even for a meanwhile much decreased target speed with consuming energy less intensively. Therefore, metro trains in peak hours may take comparatively big FSs, relatively high target speeds, and RTCs over 0.50 to meet usually urgent and large-scale travel demands in such time. In contrast, trains in nonpeak hours ought to have small FSs, relatively low target speeds, and RTCs smaller than 0.50 for mainly avoiding energy waste.

    The objective of this study was to identify demographic, social and structural factors associated with intake of fruit and vegetables in older adults in New Orleans, Louisiana. A cross-sectional randomly sampled, address-based telephone survey of households in Orleans Parish, Louisiana was conducted with the household's main grocery shopper. All participants were in the New Orleans metro area and were surveyed in 2011. Participants were 2,834 residents identified as the households' main grocery shopper in Orleans Parish, Louisiana. Participants were primarily female (75%), African-American (53%), approximately 10 percent of the sample reported receipt of government assistance. Approximately 37% of the sample was age 65 and older. Measures included a telephone administered survey assessing demographic characteristics, food intake, access to supermarkets and other food sources, transportation, self-reported health, and frequency of grocery shopping. Older adults consumed fewer fresh fruits and vegetables (FV) than younger adults (p<0.01). Bivariate associations with decreased FV included older age, receipt of government assistance, African American race, use of mobility aid, and poorer health. Multivariate factors associated with lower consumption include age, African American race, and poorer self-reported health. Women reported more fruit and vegetable consumption than men. FV consumption is associated with improved health and reduced mortality. Older adults are less likely to consume fruits and vegetables, therefore addressing reduced FV consumption in older adults is a potential target for improving health outcomes in older adults. Specifically targeting African Americans and those with poorer health, as well as males may be an important focus for interventions.

    A Korean urban contamination model METRO-K (Model for Estimates the Transient behavior of RadiOactive materials in the Korean urban environment), which is capable of calculating the exposure doses resulting from radioactive contamination in an urban environment, is taking part in a model testing program EMRAS (Environmental Modelling for RAdiation Safety) organized by the IAEA (International Atomic Energy Agency). For radioactive contamination scenarios of Pripyat districts and a hypothetical RDD (Radiological Dispersal Device), the predicted results using METRO-K were submitted to the EMRAS's urban contamination working group. In this paper, the predicted results for the contamination scenarios of a pripyat district were shown in case of both without remediation measures and with ones. Comparing with the predicted results of the models that have taken part in EMRAS program, a feasibility for decision-making support of METRO-K was investigated. As a predicted result of METRO-K, to take immediately remediation measures following a radioactive contamination, if possible, might be one of the best ways to reduce exposure dose. It was found that the discrepancies of predicted results among the models are resulted from 1) modeling approaches and applied parameter values, 2) exposure pathways which are considered in models, 3) assumptions of assessor such as contamination surfaces which might affect to an exposure receptor and their sizes, 4) parameter values which are related with remediation measures applied through literature survey. It was identified that a Korean urban contamination model METRO-K is a useful tool for decision-making support through the participation of EMRAS program

    Sepsis is a disease that affects primarily the aged. Although mortality is higher in both older septic patients and aged septic mice, the mechanisms underlying decreased survival in older hosts are incompletely understood. New work by Inoue and colleagues demonstrates persistent inflammation and T-cell exhaustion in older septic patients and aged septic mice. The clinical significance of these findings is manifested not only in increased mortality but also in a marked difference in secondary infections in older patients as long as a month following ICU admission.

    The first goal of this study is to see if social relationships in the church influence feelings of gratitude toward God. The second goal is to assess the impact of race and ethnicity on this relationship. The data support the following hypotheses: (1) older people who go to church more often tend to receive more spiritual support from fellow church members; (2) older adults who receive more spiritual support at church will derive a deeper understanding of themselves and others; (3) older people who develop greater insight into themselves and others will derive a greater sense of religious meaning in life; and (4) older adults who develop a deeper sense of religious meaning in life will feel more grateful to God. The results also indicate that the study model explains how feelings of gratitude toward God arise among older blacks and whites, but not older Mexican Americans.

    The first goal of this study is to see if social relationships in the church influence feelings of gratitude toward God. The second goal is to assess the impact of race and ethnicity on this relationship. The data support the following hypotheses: (1) older people who go to church more often tend to receive more spiritual support from fellow church members; (2) older adults who receive more spiritual support at church will derive a deeper understanding of themselves and others; (3) older people who develop greater insight into themselves and others will derive a greater sense of religious meaning in life; and (4) older adults who develop a deeper sense of religious meaning in life will feel more grateful to God. The results also indicate that the study model explains how feelings of gratitude toward God arise among older blacks and whites, but not older Mexican Americans. PMID:23543840

    Study Objective: To determine the peak bone mass density among residents of Metro Manila using dual X-ray absorptiometry (DEXA). Design: Cross-sectional study. Setting: Philippine General Hospital, a university based tertiary care hospital, and St. Luke's Medical Center, a private tertiary care center. Subjects: Forty five (45) healthy subjects aged 15-50 years old, all current residents of Metro Manila, were randomly chosen from among hospital companions were included in the study. There were 23 females and 22 males, with 3 to 4 subjects for each age range of 5. Methods: Bone mass density measurements on the lumbar spine and the femur using dual X-ray absorptiometry (DPXL Lunar) were taken. The values were also age-matched and matched with that of a young adult based on programmed Caucasian norm provided by Lunar Co. The values were then scattered against age for each sex. Ten (10) cc of blood was also extracted from the patients, with the 5 cc of blood separated for future studies. Parathormone assay and biochemistry examinations were also done. Patents were also interviewed as to their lifestyle, diet, use of contraceptive pill or hormonal replacement treatment, using a Filipino version of the revised questionnaire on the WHO Study on Osteoporosis. Dietary content was estimated using a previous day food recall. Results: The mean weight and height for females were 59.48±16.34 kg and 153.52±5.09 cm respectively, and for males, 58.14±10.06 kg and 162.52±6.75 cm respectively. The mean bone mass density at the L 2 L 4 level for females was 1.12±0.11 g/cm 2 and 0.91±0.11 g/cm 2 at the femur. The highest BMD in both the lumbar spine femoral neck measurements among females was achieved among those aged 30-35 years of age with the lowest BMD occurring between 15-19 and 45-50 years of age in the lumbar spine among female subjects. The highest BMD at the lumbar spine and the femoral neck among males was achieved between the ages 30-35 years of age with the lowest IND

    Full Text Available Just as the body and its functions undergo changes with age, in the same way sexuality shares this aging process. However, remember a golden rule that we are sexual since we are born until we die; only possibilities are modified with the passage of the years. This article intends to show the changes that occur in the sexual response of the elderly. If sexual life during youth was pleasant and satisfactory this will condition sexuality in the socalled third age and the elderly seek to maintain it, this is not the case for those who had a dysfunctional past. This article briefly describes the andropause and the SIM, vicissitudes, changes and differences in sexual response and chances to maintain eroticism in the older adult.

    Communication is an essential aspect of life, yet it can be taken for granted. Its centrality to being in the world and in professional practice often becomes evident when nurses and older adults encounter communication difficulties. The factors that can affect nurses' communication with older adults relate to the older adult, the nurse, sociocultural considerations and the environment, and the interactions between these factors. In adopting a person-centred approach to communicating with older adults, it is necessary to get to know the person as an individual and ensure communication meets their needs and abilities. Effective communication is essential in nursing practice and requires professional competence and engagement. This article can be used by nurses to support effective communication with older adults across the continuum of care.

    Dehydration affects 20% to 30% of older adults. It has a greater negative outcome in this population than in younger adults and increases mortality, morbidity, and disability. Dehydration is often caused by water deprivation in older adults, although excess water loss may also be a cause. Traditional markers for dehydration do not take into consideration many of the physiological differences present in older adults. Clinical assessment of dehydration in older adults poses different findings, yet is not always diagnostic. Treatment of dehydration should focus on prevention and early diagnosis before it negatively effects health and gives rise to comorbidities. The current article discusses what has most thoroughly been studied; the best strategies and assessment tools for evaluation, diagnosis, and treatment of dehydration in older adults; and what needs to be researched further.

    Preliminary analyses of waters for uranium and other trace elements from deepwells operated by the Metropolitan Waterworks and Sewerage System (MWSS) in Metro Manila were performed. Uranium, which ranged from 0.2 ppb to 6 ppb, was correlated with saltwater intrusion. Values >=0.8 ppb for uranium were considered indicative of saline water intrusion in the aquifers. Saline water intrusions in Malabon, Navotas, Paranaque, Las Pinas, Bacoor, Imus, Kawit, Pasig, Antipolo, San Mateo, Taguig, Cainta, Taytay, Alabang and Muntinlupa were noted. Most of these areas were also identified by MWSS as being affected by saltwater intrusion. Tritium values ranged from 0 (below detection limits) to 44 tritium units. Except for one well in Muntinlupa, all the values obtained were below the lower limit of detection of 30.83 T.U. Mercury contents in six well locations had values above the maximum limit set by the National Standards for Drinking Water. Four wells exceeded the permissible level for manganese while two wells had iron concentrations greater than the National Standards. Other trace element concentrations such as Cr, Pb, Zn, Co and Ni either did not exceed their permissible levels or were not included in the National Standards. (Auth.). 6 refs.; 1 tab.; 3 figs

    Full Text Available Speech humor in MTGW program is assumed as a "good practice" of pragmatic strategy to entertain, inspire and motivate audience. The focus and objective of this study is to get a description of the pragmatic strategy of harmonizing word choice, sentence, and humorous language in MTGW program. How pragmatic strategies have implications for the use of words, sentences, and language styles so that the audience feel entertained and laughed. This research uses desciptive qualitative approach. Data in the form of humorous languages is collected by listening and recording. The method of analysis is padan and agih. The word data, sentence, and style of the humorous language are linked and compared to other words, sentences, and language styles in terms of humorous sense between sentences produced and comparator sentences. As a result, the pragmatic strategy MT uses in the MTGW program on Metro TV is to harmonize between lingual units of words, sentences, and language styles with humor and courtesy. MT uses a locusive and illocusive strategy with humorous tones and politeness in choosing, organizing and producing every word, sentence, and style of humor. Through the choice of words, sentences, and language style, the MT uses pragmatic strategies in conveying his message as a motivator and the perlocutionary effect is that the audience becomes interested or entertained.

    Full Text Available Haloacetic acids are found in chlorinated water with high organic matter content. An analytical method based on a US EPA method for measuring these compounds in water is described. The optimized method used diethyl ether as extraction solvent with sulphuric acid-methanol as esterification agent and subsequent detection by gas chromatography-electron capture detection. Evaluation of this method showed that it was linear in the concentration range of 10 to 150 µg L-1 and the method detection limits were from 17 to 57 µg L-1. Although the method demonstrated low recoveries (16 to 43%, it is useful in the quantitative determination of monochloroacetic acid as well as the qualitative determination of other haloacetic acids in water. Drinking water samples taken from different areas in Metro Manila serviced by the local treatment plants were analysed using the method. Monochloroacetic acid, monobromoacetic acid, and bromochloroacetic acid were detected in these samples. Monochloroacetic acid was quantified and found in concentrations ranging from 19 to 157 µg L-1. In most of the water samples, the concentration of monochloroacetic acid exceeded the US EPA maximum allowable total concentration of 60 µg L-1 for the five haloacetic acids (monochloro-, dichloro-, trichloro-, monobromo-, and dibromoacetic acids in drinking water. This initial study established the occurrence of potentially harmful haloacetic acids in the local drinking water supplies.

  8. Defining Robust Recovery Solutions for Preserving Service Quality during Rail/Metro Systems Failure

    Directory of Open Access Journals (Sweden)

    Luca D'Acierno

    2016-11-01

    Full Text Available In this paper, we propose a sensitivity analysis for evaluating the effectiveness of recovery solutions in the case of disturbed rail operations. Indeed, when failures or breakdowns occur during daily service, new strategies have to be implemented so as to react appropriately and re-establish ordinary conditions as rapidly as possible. In this context, the use of rail simulation is vital: for each intervention strategy it provides the evaluation of interactions and performance analysis prior to actually implementing the corrective action. However, in most cases, simulation tasks are deterministic and fail to allow for the stochastic distribution of train performance and delays. Hence, the strategies adopted might not be robust enough to ensure effectiveness of the intervention. We therefore propose an off-line procedure for disruption management based on a microscopic and stochastic rail simulation which considers both service operation and travel demand. An application in the case of a real metro line in Naples (Italy shows the benefits of the proposed approach in terms of service quality.

    Ambient fine particulate matter (PM 2 .5) levels at the Metro Manila air sampling stations of the Philippine Nuclear Research Research Institute were found to be above the WHO guideline value of 10 μg m 3 indicating, in general, very poor air quality in the area. The elemental components of the fine particulate matter were obtained using the energy-dispersive x-ray fluorescence spectrometry. Positive matrix factorization, a receptor modelling tool, was used to identify and apportion air pollution sources. Location of probable transboundary air pollutants were evaluated using HYSPLIT (Hybrid Single Particle Lagrangian Integrated Trajectory Model) while location of probable local air pollutant sources were determined using the conditional probability function (CPF). Air pollutant sources can either be natural or anthropogenic. This study has shown natural air pollutant sources such as volcanic eruptions from Bulusan volcano in 2006 and from Anatahan volcano in 2005 to have impacted on the region. Fine soils was shown to have originated from China's Mu US Desert some time in 2004. Smoke in the fine fraction in 2006 show indications of coming from forest fires in Sumatra and Borneo. Fine particulate Pb in Valenzuela was shown to be coming from the surrounding area. Many more significant air pollution impacts can be evaluated with the identification of probable air pollutant sources with the use of elemental fingerprints and locating these sources with the use of HYSPLIT and CPF.

  11. Geological and geotechnical characteristics of Metro Manila volcanic soils and their suitability for landfill soil liner

    Due to the Philippines's island-arc setting, andesitic tuff and volcanic ash constitute two-thirds of the country's agricultural land. In situ weathering of these volcanic sediments produces volcanic soils. Metro Manila volcanic soils were studied to determine their suitability for landfill soil liner. The soils were analyzed using XRD and XRF, and were tested for geotechnical properties. The results show the presence of the smectite group, a swelling variety of clay. The smectite-type clays are weathering products of volcanic glasses which are dominant components of the parental rocks. The high amounts of Al2O3 indicate an Al-rich type of soil. The clay species is either di- or tri-octahedral type, which points to montmorillonite as the main clay species. Swelling clay lowers the permeability of soils and reduces the infiltration and lateral movement of leachates in the ground. Also, geotechnical tests revealed moderate to high plasticity indices and low hydraulic conductivity values. The study shows that the physicochemical characteristics of volcanic soils meet the criteria for a soil liner for future sanitary landfill projects as mandated by RA 9003, a recently ratified solid waste management act of the Philippines. Being widespread, volcanic soils can be viewed as an important resource of the country.

    Worldwide demand for bandwidth has been growing fast for some years and continues to do so. To cover this, mega datacentres need scalable connectivity to provide rich connectivity to handle the heavy traffic across them. Therefore, hardware infrastructures must be able to play different roles according to service and traffic requirements. In this context, software defined networking (SDN) decouples the network control and forwarding functions enabling the network control to become directly programmable and the underlying infrastructure to be abstracted for applications and network services. In addition, elastic optical networking (EON) technologies enable efficient spectrum utilization by allocating variable bandwidth to each user according to their actual needs. In particular, flexible transponders and reconfigurable optical add/drop multiplexers (ROADMs) are key elements since they can offer degrees of freedom to self adapt accordingly. Thus, it is crucial to design control methods in order to optimize the hardware utilization and offer high reconfigurability, flexibility and adaptability. In this paper, we propose and analyze, using a simulation framework, a method of capacity maximization through optical power profile manipulation for inter datacentre links that use existing metropolitan optical networks by exploiting the global network view afforded by SDN. Results show that manipulating the loss profiles of the ROADMs in the metro-network can yield optical signal-to-noise ratio (OSNR) improvements up to 10 dB leading to an increase in 112% in total capacity.

    With a minimum of 6000 tonnes/day municipal waste output, and with NO existing operational sanitary landfill and with incineration illegal, Metro Manila has a very serious solid waste disposal problem. Unsorted municipal waste are being piled in open dumps, the most notorious of which is the Payatas open dump. A recent, tragic garbage-slide in this open dump caused dozens of deaths, news of which were broadcast internationally. Political expediency laced with a lot of corruption, rather than sound science, was the main basis for selecting this site as an open dump. As an example, this dump is situated plastics. Several cross-sections cut across the dump show that the side slopes of the dump are on the average steeper than the pre-dump slopes. The “bedrock” of the Payatas dump are conglomerate members of the Pleistocene volcaniclastic Guadualupe Formation. Studies are still to be done on the extent of pollution on surface and groundwater in the Payatas environs.

  16. Influence of current pulse shape on directly modulated system performance in metro area optical networks

    Due to the fact that a metro network market is very cost sensitive, direct modulated schemes appear attractive. In this paper a CWDM (Coarse Wavelength Division Multiplexing) system is studied in detail by means of an Optical Communication System Design Software; a detailed study of the modulated current shape (exponential, sine and gaussian) for 2.5 Gb/s CWDM Metropolitan Area Networks is performed to evaluate its tolerance to linear impairments such as signal-to-noise-ratio degradation and dispersion. Point-to-point links are investigated and optimum design parameters are obtained. Through extensive sets of simulation results, it is shown that some of these shape pulses are more tolerant to dispersion when compared with conventional gaussian shape pulses. In order to achieve a low Bit Error Rate (BER), different types of optical transmitters are considered including strongly adiabatic and transient chirp dominated Directly Modulated Lasers (DMLs). We have used fibers with different dispersion characteristics, showing that the system performance depends, strongly, on the chosen DML-fiber couple.

  19. What's different about older people.

    Science.gov (United States)

    Crome, Peter

    2003-10-01

    Older people can be regarded as a marginalised group within society from a number of perspectives including that of health. When it comes to the use of medication older people have suffered from a double whammy. Not only are they more at risk from the adverse effects of drugs but also their involvement in clinical trials has been limited so that rational prescribing both to maximise benefit and to reduce risk has been problematic. Their special problems have been recognised formerly by the Department of Health in its NSF for Older People [National Service Framework for Older People. Department of Health, London (2001a)], [Medicines and Older People. Implementing medicines-related aspects of the NSF for Older People. Department of Health (2001b)]. Early studies focussed on compliance, the avoidance of poly-pharmacy and the high prevalence of adverse effects of drugs and the reasons for this. Studies in long-stay patients showed dramatic differences in pharmacokinetics between such older people and young healthy volunteers. Initially such differences were ascribed to age alone and the overall message became "start low and go slow". Studies in healthy older people then revealed that age differences in drug metabolism were, as a rule, not so marked although clearance of renally excreted drugs was reduced in line with the age associated decline in renal function. Including older people in clinical trials poses challenges. Many traditional trialists do not have ready access to older people, co-morbidity and poly-pharmacy are common and most people feel reluctant to ask older people to take part in complex and potentially hazardous trials. Concern about compliance is unwarranted. Adverse events may be more serious. Thus in a younger patient postural hypotension may make a subject unsteady but in an older subject the unsteadiness may lead to a fall, the fall to a fracture, and the fracture to poor recovery. The choice of end-points is crucial. Although reduction of

  20. Industrial irradiation

    International Nuclear Information System (INIS)

    Stirling, Andrew

    1995-01-01

    Production lines for rubber gloves would not appear to have much in common with particle physics laboratories, but they both use accelerators. Electron beam irradiation is often used in industry to improve the quality of manufactured goods or to reduce production cost. Products range from computer disks, shrink packaging, tyres, cables, and plastics to hot water pipes. Some products, such as medical goods, cosmetics and certain foodstuffs, are sterilized in this way. In electron beam irradiation, electrons penetrate materials creating showers of low energy electrons. After many collisions these electrons have the correct energy to create chemically active sites. They may either break molecular bonds or activate a site which promotes a new chemical linkage. This industrial irradiation can be exploited in three ways: breaking down a biological molecule usually renders it useless and kills the organism; breaking an organic molecule can change its toxicity or function; and crosslinking a polymer can strengthen it. In addition to traditional gamma irradiation using isotopes, industrial irradiation uses three accelerator configurations, each type defining an energy range, and consequently the electron penetration depth. For energies up to 750 kV, the accelerator consists of a DC potential applied to a simple wire anode and the electrons extracted through a slot in a coaxially mounted cylindrical cathode. In the 1-5 MeV range, the Cockcroft-Walton or Dynamitron( R ) accelerators are normally used. To achieve the high potentials in these DC accelerators, insulating SF6 gas and large dimension vessels separate the anode and cathode; proprietary techniques distinguish the various commercial models available. Above 5 MeV, the size of DC accelerators render them impractical, and more compact radiofrequency-driven linear accelerators are used. Irradiation electron beams are actually 'sprayed' over the product using a magnetic deflection system. Lower energy beams of

  1. Aluminum industry options paper

    International Nuclear Information System (INIS)

    1999-10-01

    In 1990, Canada's producers of aluminum (third largest in the world) emitted 10 million tonnes of carbon dioxide and equivalent, corresponding to 6.4 tonnes of greenhouse gas intensity per tonne of aluminum. In 2000, the projection is that on a business-as-usual (BAU) basis Canadian producers now producing 60 per cent more aluminum than in 1990, will emit 10.7 million tonnes of carbon dioxide and equivalent, corresponding to a GHG intensity of 4.2 tonnes per tonne of aluminum. This improvement is due to production being based largely on hydro-electricity, and partly because in general, Canadian plants are modern, with technology that is relatively GHG-friendly. The Aluminum Association of Canada estimates that based on anticipated production, and under a BAU scenario, GHG emissions from aluminum production will rise by 18 per cent by 2010 and by 30 per cent by 2020. GHG emissions could be reduced below the BAU forecast first, by new control and monitoring systems at some operations at a cost of $4.5 to 7.5 million per smelter. These systems could reduce carbon dioxide equivalent emissions by 0.8 million tonnes per year. A second alternative would require installation of breaker feeders which would further reduce perfluorocarbon (PFC) emissions by 0.9 million tonnes of carbon dioxide equivalent. Cost of the breakers feeders would be in the order of $200 million per smelter. The third option calls for the the shutting down of some of the smelters with older technology by 2015. In this scenario GHG emissions would be reduced by 2010 by 0.8 million tonnes per year of carbon dioxide equivalent. However, the cost in this case would be about $1.36 billion. The industry would support measures that would encourage the first two sets of actions, which would produce GHG emissions from aluminum production in Canada of about 10.2 million tonnes per year of carbon dioxide equivalent, or about two per cent above 1990 levels with double the aluminum production of 1990.

    The Internet is entering an era of cloud computing to provide more cost effective, eco-friendly and reliable services to consumer and business users and the nature of the Internet traffic will undertake a fundamental transformation. Consequently, the current Internet will no longer suffice for serving cloud traffic in metro areas. This work proposes an infrastructure with a unified control plane that integrates simple packet aggregation technology with optical express through the interoperation between IP routers and electrical traffic controllers in optical metro networks. The proposed infrastructure provides flexible, intelligent, and eco-friendly bandwidth on demand for cloud computing in metro areas.

    We propose and demonstrate a novel optical orthogonal frequency-division multiple access (OFDMA)-based metro-access integrated network with dynamic resource allocation. It consists of a single fiber OFDMA ring and many single fiber OFDMA trees, which transparently integrates metropolitan area networks with optical access networks. The single fiber OFDMA ring connects the core network and the central nodes (CNs), the CNs are on demand reconfigurable and use multiple orthogonal sub-carriers to realize parallel data transmission and dynamic resource allocation, meanwhile, they can also implement flexible power distribution. The remote nodes (RNs) distributed in the user side are connected by the single fiber OFDMA trees with the corresponding CN. The obtained results indicate that our proposed metro-access integrated network is feasible and the power distribution is agile.

  9. Splitting Travel Time Based on AFC Data: Estimating Walking, Waiting, Transfer, and In-Vehicle Travel Times in Metro System

    Full Text Available The walking, waiting, transfer, and delayed in-vehicle travel times mainly contribute to route’s travel time reliability in the metro system. The automatic fare collection (AFC system provides huge amounts of smart card records which can be used to estimate all these times distributions. A new estimation model based on Bayesian inference formulation is proposed in this paper by integrating the probability measurement of the OD pair with only one effective route, in which all kinds of times follow the truncated normal distributions. Then, Markov Chain Monte Carlo method is designed to estimate all parameters endogenously. Finally, based on AFC data in Guangzhou Metro, the estimations show that all parameters can be estimated endogenously and identifiably. Meanwhile, the truncated property of the travel time is significant and the threshold tested by the surveyed data is reliable. Furthermore, the superiority of the proposed model over the existing model in estimation and forecasting accuracy is also demonstrated.

  10. Why does Bogota not have at least one metro line? And the reasons why it will probably not have one

    Full Text Available Although the decision on the first metro line in Bogotá was first sketched out 75 years ago, the city still does not have it, but there is no academic reflection on the reasons for such delay. During this period, the physical and institutional capital dedicated to mobility has deteriorated to the point of capsizing the system of mass passenger transport. The result is visible in the substantial increase in unproductive travel time, traffic congestion, saturation of the fleet intended for collective mobility and personal insecurity to which users are exposed. This article supports the idea that in a metropolis of eight million people, with powerful infrastructure inflexibility, the layout of the priority metro line should be resolved in favor of connecting the most densely populated areas of the city, which would progressively solve investment lags and would provide increased ecological and financial sustainability of the system of mass transit.

  12. Industrial radiography

    International Nuclear Information System (INIS)

    1992-01-01

    Industrial radiography is a non-destructive testing (NDT) method which allows components to be examined for flaws without interfering with their usefulness. It is one of a number of inspection methods which are commonly used in industry to control the quality of manufactured products and to monitor their performance in service. Because of its involvement in organizing training courses in all the common NDT methods in regional projects in Asia and the Pacific and Latin America and the Caribbean and in many country programmes, the Agency is aware of the importance of standardizing as far as possible the syllabi and training course notes used by the many experts who are involved in presenting the training courses. IAEA-TECDOC-628 ''Training Guidelines in Non-destructive Testing'' presents syllabi which were developed by an Agency executed UNDP project in Latin America and the Caribbean taking into account the developmental work done by the International Committee for Non-destructive Testing. Experience gained from using the radiography syllabi from TECDOC-628 at national and regional radiography training courses in the Agency executed UNDP project in Asia and the Pacific (RAS/86/073) showed that some guidance needed to be given to radiography experts engaged in teaching at these courses on the material which should be covered. The IAEA/UNDP Asia and Pacific Project National NDT Coordinators therefore undertook to prepare Radiography Training Course Notes which could be used by experts to prepare lectures for Level 1,2 and 3 radiography personnel. The notes have been expanded to cover most topics in a more complete manner than that possible at a Level 1, 2 or 3 training course and can now be used as source material for NDT personnel interested in expanding their knowledge of radiography.

    2012-11-15

    Attiko Metro S.A., the state company ensuring the development of the Athens Metro network, has recently initiated a new extension of 7.6 km, has planned for line 3 of Athens Metro from Haidari to Piraeus "Dimotikon Theatre" towards "University of Piraeus" (forestation), connecting the major Piraeus Port with "Eleftherios Venizelos" International Airport. The Piraeus extension consists of a Tunnel Boring Machine, 2 tracks and, tunnel sections, as well as 6 stations and a forestation (New Austrian Tunnelling Method) at the end of the alignment. In order to avoid the degradation of the urban acoustic environment from ground borne noise and vibration during metro operation, the assessment of the required track types and possible noise mitigation measures was executed, and for each section and each sensitive building, the ground borne noise and vibration levels will be numerically predicted. The calculated levels were then compared with ground borne noise and vibration level criteria. The necessary mitigation measures were defined in order to guarantee, in each location along the extension, the allowable ground borne Noise and Vibration max. levels inside nearby sensitive buildings taking into account alternative Transfer Functions for ground borne noise diffusion inside the buildings. Ground borne noise levels were proven to be higher than the criterion where special track work is present and also in the case of the sensitive receptor: "Dimotikon Theatre". In order to reduce the ground borne noise levels to allowable values in these sections, the installation of tracks and special track work on a floating slab was assessed and recommended.

    2012-01-01

    Ageist attitudes have been identified across different industries. The nursing profession has a high proportion of older workers. As this facilitates regular contact with, as well as exposure to, older nurses, it may be expected to show less ageism. This study investigated 163 Western Australian nursing recruiters' attitudes toward older nurses. Results showed clear evidence of both negative and positive stereotyping of older nurses. Nursing recruiters indicated that they would be more than likely to hire older nurses and that age was less relevant in making hiring decisions. These findings suggest that enhancing the employability of older workers does not necessarily change ageist attitudes. This is relevant to policy formulation, attitude change interventions, and the well-being of older workers.

    Sexual health is a key public health issue. The older woman faces a number of changes to her sexual health, wellbeing and sexuality. These changes result in many older women having to adapt to a series of complex transitions that can be challenging. This article aims to identify and explore some of these changes and how they can have a significant impact on women's quality of life. Nurses play an important role in assessing and helping women to manage normal and pathological age-related changes in order to improve the sexual health of older women and ensure they receive the advice and support needed at this stage of their life.

    Full Text Available Public bicycle acts as a seamless feeder mode in combination with the citywide public transit, as well as a competitor for the inner-city short trips. The primary objective of this study is to address the layout planning of public bicycle system within the attracted scope of a metro station. Based on the land use function, population, and bicycle mode share, bicycle rental stations are divided into three types, namely, the metro station, district station, and resident station, and later the quantity of bicycle facilities in each rental station is estimated. Then, the service stations are selected from these bicycle rental stations to provide the service of periodical bicycle redistribution. An improved immune algorithm is proposed to determine the number and locations of service stations and the optimal route options for the implement of redistributing strategy. Finally, a case study of Nanjing Tianyin Road metro station is conducted to illustrate the proposed model and clarify some of its implementation details.

    Full Text Available Increasing attention is being paid to the energy efficiency in metro systems to reduce the operational cost and to advocate the sustainability of railway systems. Classical research has studied the energy-efficient operational strategy and the energy-efficient system design separately to reduce the traction energy consumption. This paper aims to combine the operational strategies and the system design by analyzing how the infrastructure and vehicle parameters of metro systems influence the operational traction energy consumption. Firstly, a solution approach to the optimal train control model is introduced, which is used to design the Optimal Train Control Simulator(OTCS. Then, based on the OTCS, the performance of some important energy-efficient system design strategies is investigated to reduce the trains’ traction energy consumption, including reduction of the train mass, improvement of the kinematic resistance, the design of the energy-saving gradient, increasing the maximum traction and braking forces, introducing regenerative braking and timetable optimization. As for these energy-efficient strategies, the performances are finally evaluated using the OTCS with the practical operational data of the Beijing Yizhuang metro line. The proposed approach gives an example to quantitatively analyze the energy reduction of different strategies in the system design procedure, which may help the decision makers to have an overview of the energy-efficient performances and then to make decisions by balancing the costs and the benefits.

    The configuration of urban areas is the result of a cyclic relationship between land use and transportation system: the changes in transportation system arrangements influence the localisation of residence and economic activities, as well as the changes in land use affect transportation system characteristics. In this context, by operating on land use, travel demand can be shift from the individual transportation modes to transit systems. In the literature, many conceptual models were proposed to describe the complex relationship between land use and travel behaviour. In addition to spatial variation, the study of travel demand shows the categorical variation of variables. This work aims to analyse the influence of the categorical variation of variables impacting on transit use. An ordered probit model is proposed for evaluating how transit use depends on variables related to socio-economic characteristics of population, territorial features, accessibility, and transportation system. The study case is Madrid metro network (Spain). The results show a strong influence of characteristics of population and land use variables on daily trips made using metro system and highlighted the aspects that mainly impact on the choice to travel by metro, providing useful suggestions for shifting people from individual transportation mode to transit systems.

    This social science case study examines the sex trafficking of women and girls in Metro Manila through a public health lens. Through key informant interviews with 51 health care and anti-trafficking stakeholders in Metro Manila, this study reports on observations about sex trafficking in Metro Manila that provide insight into understanding of risk factors for sex trafficking at multiple levels of the social environment: individual (for example, childhood abuse), socio-cultural (for example, gender inequality and a "culture of migration"), and macro (for example, profound poverty caused, inter alia, by environmental degradation disrupting traditional forms of labor). It describes how local health systems currently assist sex-trafficking victims, and provides a series of recommendations, ranging from prevention to policy, for how health care might play a larger role in promoting the health and human rights of this vulnerable population.

    Full Text Available In article was formulated and solved the problem of conditional nonlinear optimization of the distance between inter-mediate supports during the design of the cable metro lines in highly urbanized environment, taking into account not the horizontal surface of the terrain. The optimization problem involves a single-criterion objective function that expresses the cost of construction of the cable metro line (total cost of intermediate supports and their foundations, traction and carrying steel cables and technical equipment. The specified objective function subject to minimization by finding the optimal combination of the distance between intermediate supports and tension carrying ropes with accounting con-structive, modal, structural and planning constraints in the form of nonlinear inequalities. When constructing the objec-tive function were considered three possible forms sagging of carrying ropes, which can be implemented for various values of the efforts of their tension. Analysis was done of the influence of the angle of the longitudinal slope of the surface relief along the line of the cable metro on the value of the optimal distance between intermediate supports de-pending on the design and cost of intermediate supports and at the cost of 1 km line of the cable metro. Quantitative calculations showed that with the increase of the longitudinal slope of the surface construction cost also increases with nonlinear increasing rate. The dependence of the cost of 1 km of line underground cable metro from the parameters of the relief is of extreme character with a pronounced minimum at small angles of inclination of the terrain surface about 3...60 degrees. The position of the minimum is quite stable and only slightly changes when enough significant change in the cost of intermediate supports and installed on them technological equipment. The most effective conditions for the construction of the cable metro is the terrain with considerable

  10. Wage determination and discrimination among older workers.

    Quinn, J F

    1979-09-01

    In this study, the determinants of the wage rates of a large sample of individuals aged 58 to 63 are first analyzed. Second, an explanation for the large discrepancies existing between the average wage rates earned by whites and nonwhites and by men and women is attempted. Human capital and geographic variables were found to be important wage determinants. Education, vocational training, years of job tenure, health, region of residence and local cost of living were significant explanators, especially for whites. Differences in these variables, however, cannot completely explain the wage differentials that exist by race and sex. There is a large unexplained component (especially in the male-female comparison) offering evidence of race and sex discrimination among older workers. In the case of sex discrimination, much of the problem appears to be occupational segregation--the crowding of women into low paying industries and occupations.

    Faced with aging societies, there is an immense need to better understand the nature of volunteering outside advanced Western industrial countries. As a case of a rapidly aging society, we identify robust factors associated with elderly volunteering in Korea in terms of a resource framework. Data were derived from the Social Statistics Survey conducted by the Korea National Statistical Office in 1999 (N = 7,135) and 2003 (N = 8,371). We first determined overall and age-related volunteer rates for Korea compared to the United States. Using logistic regression, we then examined the effects of human, cultural, and social capital variables on volunteering. Approximately 6% of Koreans aged 65 years and older participate in volunteer programs. All human capital variables are positively related with volunteering. For cultural capital, those who identify their religion as Buddhism or Catholicism are more likely to volunteer than those who have no religion. But surprisingly, Protestantism does not consistently promote volunteering across both years. For social capital, older adults who live alone or with a spouse are more likely to volunteer than those living with both a spouse and children. In contrast to human capital, cultural and social capital on elderly volunteering appears to be contoured by social contexts.

    The air pollution induced by various transportation means combines the emission of pollutants with the simultaneous presence of people. In this respect, the scientific community has focused its efforts in studying both the air quality within busy streets and inside cars, buses and the underground railway network in order to identify the pollutants' sources and levels as well as the human exposure. The impact of the air pollution on commuters of the underground may be more severe because it is a confined space, extended mostly under heavily trafficked urban streets, relies on mechanical ventilation for air renewal and gathers big numbers of passengers. The purpose of the present work is to monitor the air quality of the city of Athens Metro Network cabins and platforms during the unusually hot summer of 2012. For that cause particulate matter (PM10, PM2.5, PM1), carbon dioxide (CO2), the number of commuters along with temperature (T) and humidity (RH) were recorded inside the Athens Metro Blue Line trains (covering a route from the centre of Athens (Aigaleo) to the Athens International Airport) and on the platforms of a central (Syntagma) and a suburban-traffic (Doukissis Plakentias) station between June and August. The data collection included six different experiments that took place for 2 consecutive working days each, for a time period of 6 weeks from 6:30 am too 7:00 pm in order to account for different outdoor climatic conditions and for morning and evening rush hours respectively. Measurements were taken in the middle car of the moving trains and the platform end of the selected stations. The results show PM concentrations to be higher (approximately 2 to 5 times) inside the cabins and o the platforms of the underground network as compared to the outdoor levels monitored routinely by the Ministry of Environment. Moreover, PM1, PM2.5 and PM10 average concentrations recorded at the Syntagma Station Platform were almost constantly higher reaching 11 μg m-3 47

    In the Philippines, it has been a yearly tradition to welcome the coming of the New Year with the loudest noise as can be achieved. Firecrackers and fireworks have been a necessity for Filipinos during this time despite bans on the use of most of these and despite the Department of Health's campaign to use alternative safe practices to welcome the New Year. Data for PM{sub 1}0 samples (fractionated as PM{sub 1}0-2.5 and PM{sub 2}.5) collected from four PNRI sampling sites in Metro Manila show the air pollution impacts of fireworks on New Year's Eve. Samples were collected from 1998 to 2006 using a Gent dichotomous sampler. Particulate mass was determined by gravimetry. Elemental analysis was done using two multi-elemental non-destructive nuclear analytical techniques: X-ray Fluorescence Spectrometry (XRF) and Particle Induced X-ray Emission (PIXE). Black carbon was analyzed using reflectometry. PM{sub 1}0 values increased by two to four times the usual averages (36.4 to 55.4 {mu} m-{sup 3}) and in 2002 even exceeded the PNAAQ short-term guideline value of 150 {mu}g m-{sup 3}), even many times exceeding US EPA short-term guideline value of 35 {mu}g m-{sup 3}. The increase in the particulate mass of New Year's Day samples can be attributed more to an increase in the elemental pollutants rather than the black carbon, with higher contribution from the fine fraction. Increase in the elemental concentrations of A1, S, CI, K, Ba, Sr, Ti, V, Mn, Cu and Pb were observed with the highest contribution from K. Results show that the usual practices of burning firecrackers and fireworks during New Year's Day celebration is a very strong source of air pollution which contributes significantly high amount of elemental pollutants in the air.

    This study examined differences in food preferences and dietary intake among male and female Filipino adolescents of different nutritional status as measured by body mass index (BMI). One hundred and twenty 13-17-year olds from various schools and communities in Metro Manila, The Philippines were selected through quota sampling with BMI, sex and age as criteria. Data on mean dietary intake and food preference were collected using pretested instruments--a 3-day food record and a food preference questionnaire, respectively. Resulting values were analysed using one-way ANOVA, Bonferroni test and Pearson's product-moment and Spearman's correlation using SAS Enterprise Guide version 2. Preference for cereals prepared with added sugar or fat (p=0.21, p=.0240), and low fat meat (p=0.18, p=0.420) were found to be positively correlated with BMI, while preference for fruits that are high in vitamin A (p=-0.18, p=0.430) was negatively correlated with the said variable. Overweight respondents gave lower and significantly different preference scores to donut (p=.02780), banana cue (p=.0489) and mayonnaise (p=.0291). Respondents of different nutritional status also had statistically different intakes of fibre, calcium and phosphorus, corresponding with the positive correlation of fibre (p=0.25231, p=0.0054), calcium (p=0.2529, p=0.0134) and phosphorus (p=0.25887, p=0.0043) intake with BMI. With respect to sex, male respondents gave statistically higher preference for French fries (p=.0370), tofu (p=.0005), garlic (p=.0190) and mussels (p=.0023). Also, males have significantly higher intakes of energy and carbohydrate than female respondents. Results suggest that food preferences should be considered in the nutritional care management of malnourished adolescents.

    Air particulate samples were collected from two monitoring stations in Metro Manila using a 'Gent' type dichotomous sampler for pollutant source apportionment studies. Samples were collected in two fractions: a fine fraction with aerodynamic diameter, d p p 3 : HCL: HF, 4: 1: 1) for at least 20 minutes with subsequent heating at lower power settings for a total of 20 minutes more, effectively decomposed the sample with complete recovery of the elements. The digests were evaporated to near dryness to eliminate the troublesome effect of HF and HNO 3 and to decrease acidity of the electrolytic solution to pH ≥ 2. At pH 2, the addition of at least 0.01 M KCl was needed to improve sensitivity. The formation of Zn-Cu intermetallic compounds which interfered in the accurate quantitation of zinc was eliminated by addition of gallium as a 'third' element. The amount of gallium needed varied from sample to sample and was affected by the pH of the solution. The DPASV parameters found to be optimum for the analysis of the air particulate samples are as follows: pulse amplitude, 50 mV; scan rate, 10 mV/sec; E dep , - 1.30 V; t dep , 2 min; and RDE rotation rate, 1500 rpm. Detection limits of 0.2 ppb for zinc, 0.6 ppb for lead, and 0.05 ppb for cadmium in the sample matrix were obtained. The standard addition method was found to be reliable for the quantitative determination of the analytes in the sample. All R 2 values obtained were > 0.9900 at 95% confidence level. Validation of the established analytical methodology by analyzing certified reference standards and performing parallel analysis by GF-AAS and flame AAS showed acceptable accuracy of the DPASV measurements.

    Older women make up an increasingly important sector in the labour market. However, we know little about their health-the various influences on their health and the ways in which paid and unpaid work impact on both physical and mental well being. This paper reviews the available literature on older women's health in the workplace, focussing on work-specific and more general risks for older women, including stress, discrimination, physical hazards and the 'double burden' of paid work and caring responsibilities. Databases searched included Web of Science, CAS, CINAHL, Medline and ASSIA, together with UK and European statistical sources. We conclude with a three-point research agenda, calling for more empirical work on the risks faced by older women, studies that take a life-course perspective of women's occupational health and work that explores the interactions between unpaid and paid work in later life.

    Objectives Physician relationships with industry are receiving attention as government and professional organizations move toward restrictive policies and financial transparency. Our objective was to explore attitudes of physicians from all specialties toward gifts from and interactions with the pharmaceutical and device industries. Design Anonymous cross sectional survey. Setting Hospitals in the Mount Sinai School of Medicine consortium, in the New York City metro area Participants Faculty and trainee physicians from all clinical departments Main Outcome Measures Attitudes toward industry interactions and gifts and their appropriateness, measured on 4-point Likert scales. Results Five hundred ninety physicians and medical students completed the survey (response rate=67%); 59% were male, 39% were attendings, and 24% were from surgical specialties. Attitudes toward industry and gifts were generally positive. More than 65% found educational materials and sponsored lunches appropriate, whereas fewer than 25% considered vacations or large gifts appropriate. Surgeons, trainees, and those unfamiliar with institutional policies on industry interactions held more positive attitudes than others and were more likely to deem some gifts appropriate, including industry funding of residency programs and, among surgeons, receiving meals, travel expenses, and payments for attending lectures. Non-attendings held more positive attitudes toward meals in clinical settings, textbooks and samples. Conclusions Physicians continue to hold positive attitudes toward marketing-oriented activities of the pharmaceutical and device industries. Changes in medical culture and physician education focused on surgeons and trainees may align physician attitudes with current policy trends. PMID:20566978

    The Radiation Protection group wishes to remind CERN staff responsible for contractors performing X-ray inspections on the CERN sites that the firms must apply the legislation in force in their country of origin, in particular with regard to the prevention of risks relating to ionizing radiation. Industrial radiography firms called on to work on the CERN sites must also comply with the rules laid down in CERN's Radiation Safety Manual and be registered in the relevant CERN database. Since CERN is responsible for safety on its own site, a number of additional rules have been laid down for this kind of work, as set out in Radiation Protection Procedure PRP30 https://edms.cern.ch/file/346848/LAST_RELEASED/PRP30.pdf The CERN Staff Member responsible for the contract shall register the company and issue notification that an X-ray inspection is to be performed via the web interface at the following address: http://cern.ch/rp-radio

    Full Text Available Resumo: Com o objectivo de identificar parâmetros funcionais respiratórios que contribuam para o diagnóstico diferencial entre asma e DPOC, estudámos 20 asmáticos e 30 bronquíticos, com ou sem enfisema, com os exames usuais de função pulmonar: espirografia, pletismografia e DLCO, pré e pós-broncodilatação para os dois primeiros exames. Os grupos apresentam diferenças significativas na sua constituição. Os asmáticos são mais jovens, média de 48 anos, contra 59 anos no grupo com DPOC, e o grupo é constituído predominantemente por mulheres, 65% contra 40%, respectivamente. Os exames funcionais pulmonares, realizados conforme as directrizes internacionais, mostram, pela espirografia, que os asmáticos têm obstrução mais intensa, VEF1/CVF de 59 versus 66 e maior resposta broncodilatadora pelo VEF1, quer em valor absoluto, quer por variação percentual, do basal (% ou do valor previsto (%P. A DLCO mostra-se, em média, normal entre os asmáticos, 103%P, e diminuída no grupo com DPOC, 69%P. Na pletismografia constatámos que os asmáticos têm maior volume residual (%P e resistência de vias aéreas. Concluímos que vários parâmetros funcionais diferenciam a asma da DPOC, como um grupo; na análise individual, a DLCO é o parâmetro que melhor discrimina as duas doenças, possuindo maior especificidade para o diagnóstico de DPOC, seguida pelas variações de VEF1 na broncodilatação, com maior sensibilidade para o diagnóstico de asma. Desta forma, estes dois exames são destaque no diagnóstico diferencial das doenças obstrutivas.Rev Port Pneumol 2010; XVI (2: 253-272 Abstract: The aim of this study was to identify the respiratory function parameters that help in the accurate diagnosis of asthma and COPD.

    Full Text Available La Directiva 92/72/CE hace referencia al método de análisis descrito en la UNE 77-221:2000 y a que los analizadores de ozono se deben calibrar con un fotómetro UV de referencia o con un patrón transferido.De la necesidad de desarrollar un procedimiento que asegure la calidad y la trazabilidad de las mediciones en España, el Área de Contaminación Atmosférica ha decidido implantar un fotómetro UV de referencia NIST como patrón de ozono.Teniendo en cuenta los procedimientos empleados por EPA y NIST, se ha desarrollado un procedimiento de verificación consistente en la realización de 6 comparaciones del Patrón Transferido frente al Fotómetro UV de Referencia NIST, en días diferentes, analizándose, como mínimo, 5 concentraciones de ozono diferentes. Cada comparación se inicia y se finaliza siempre con una concentración de 0 ppb de O3. De cada comparación se obtiene una regresión lineal.Una vez realizadas las 6 comparaciones se obtiene la Recta de calibración y se calcula la incertidumbre asociada al patrón transferido.Se ha realizado la verificación de 17 patrones transferidos de los que 11 son fotómetros UV, 2 son generadores de ozono y 4 son generadores de ozono de bancos de dilución.De los resultados se concluye que las incertidumbres de los generadores de ozono, en general, son mayores que las de los fotómetros UV, recomendándose estos últimos como patrones transferidos.Destacar que mediante la utilización de los patrones transferidos para la calibración de analizadores de ozono se garantiza tanto la calidad como la trazabilidad de los datos generados.

  16. "Old Oxen Cannot Plow": Stereotype Themes of Older Adults in Turkish Folklore.

    Marcus, Justin; Sabuncu, Neslihan

    2016-12-01

    Although much research has established the nature of attitudes and stereotypes toward older adults, there are conflicting explanations for the root cause of ageism, including the sociocultural view and interpersonal views, that age bias against older adults is uniquely a product of modernity and occurs through social interactions, and the evolutionary view and intraindividual views, that age bias against older adults is rooted in our naturally occurring and individually held fear of death. We make initial investigations into resolving this conflict, by analyzing literature from a society predating the Industrial Revolution, the society of Ottoman Turks. Using Grounded Theory, we analyzed 1,555 Turkish fairy tales of the most well-known older adult in Turkish folklore, Nasreddin Hoca, for stereotype themes of older adults. Using the same method, we then analyzed 22,000+ Turkish sayings and proverbs for the same themes. Results indicated older adults to be viewed both positively and negatively. Positive stereotypes included wisdom, warmth, deserving of respect, and retirement. Negative stereotypes included incompetence, inadaptability, and frailty/nearing of death. Older females were viewed more negatively relative to older males. Results indicated views of older adults to parallel those found in contemporary research. Results have implications for the design of interventions to reduce ageism and on the cross-cultural generalizability of age-based stereotypes. © The Author 2015.

    1989-01-01

    A total of 2,878 unselected subsequent CT examinations carried out in 1984 were analyzed retrospectively. All studies were performed in a university hospital with a centralized department of diagnostic radiology. Most of the patients investigated were hospitalized; there were only 12% outpatients. Of the patients studied 12.6% were older than 65 years and 20.5% older than 60; 17.7% were emergency cases and patients between 16 and 25 years of age represented the largest fraction. In all other age groups the relative distribution between emergency cases and regular studies revealed no significant differences. There was no statistically significant difference between the older age group (patients older than 65 years) and the total population of this study in almost all items investigated, i.e., no differences in CT examination time and no differences in preparation time (time between two CT studies). The rate of abdominal CT examinations was 7% higher in the older age group, while the relative distribution of all other CT examinations was again comparable to the total population under study. Thus, the expected increase in patients in the older age group does not measurably prolong the CT examination time. This statement applies to a major referral center with a high percentage of inpatients. (orig.) [de

    Chronic pain is prevalent among older adults but is underrecognized and undertreated. The approach to pain assessment and management in older adults requires an understanding of the physiology of aging, validated assessment tools, and common pain presentations among older adults. To identify the overall principles of pain management in older adults with a specific focus on common painful conditions and approaches to pharmacologic treatment. We searched PubMed for common pain presentations in older adults with heart failure, end-stage renal disease, dementia, frailty, and cancer. We also reviewed guidelines for pain management. Our review encompassed 2 guidelines, 10 original studies, and 22 review articles published from 2000 to the present. This review does not discuss nonpharmacologic treatments of pain. Clinical guidelines support the use of opioids in persistent nonmalignant pain. Opioids should be used in patients with moderate or severe pain or pain not otherwise controlled but with careful attention to potential toxic effects and half-life. In addition, clinical practice guidelines recommend use of oral nonsteroidal anti-inflammatory drugs with extreme caution and for defined, limited periods. An understanding of the basics of pain pathophysiology, assessment, pharmacologic management, and a familiarity with common pain presentations will allow clinicians to effectively manage pain for older adults. © 2013 Elsevier HS Journals, Inc.

    1992-01-01

    For the last half decade, regulatory expectations of the procurement process for nuclear commercial-grade safety-related materials have increase. The changes have been driven by concern for fraudulent or misrepresented parts and the loss of original equipment manufacturers. The industry responded to these concerns by developing improved procurement programs that changed how parts were specified and received and provided for verification of attributes that were critical to the successful performance of safety functions(s). Like its counterparts, Duquesne Light Company (DLCo), Beaver Valley power station began applying these enhanced requirements to procurements initiated after January 1, 1990, in response to the Nuclear Management and Resources Council initiative on dedication. Procurements prior to this data were not subject to the new requirements

    Full Text Available PURPOSE: To determine calibration errors of Goldmann applanation tonometers in ophthalmic clinics of Brasília, Brazil, and correlate the findings with variables related to tonometers model and utilization. METHODS: Tonometers from ophthalmic clinics in Brasília, Brazil, were checked for calibration errors. A standard Goldmann applanation tonometer checking tool was used to asses the calibration error. Only one trained individual made all verifications, with a masked reading of the results. Data on the model, age, daily use, frequency of calibration checking and the nature of the ophthalmic department - private or public - were collected and correlated with the observed errors. RESULTS: One hundred tonometers were checked for calibration. Forty seven percent (47/100 were out of 1 mmHg range at least at one point checking. Tonometers mounted to slit lamp, with less than 5 years, used in less than 20 patients daily, that had a calibration check on a yearly basis, and those from private office exhibit a lower rate of inaccuracy, but only the first variable was statistically significant. Sixty one percent of tonometers on public hospitals were out of calibration. CONCLUSION: Calibration of tonometers in the capital of Brazil is poor; those from general hospitals are worst, and this fact can lead to inaccurate detection and assessment of glaucoma patients, overall in the population under government assistance.OBJETIVOS: Determinar os erros de calibração dos tonômetros de aplanação de Goldmann em clínicas oftalmológicas de Brasília, Brasil, e correlacioná-los a variáveis relativas ao modelo e à utilização dos aparelhos.

    System-representative commuter air pollution exposure data were collected for the metro systems of Toronto, Montreal, and Vancouver, Canada. Pollutants measured included PM 2.5 (PM = particulate matter), PM 10 , ultrafine particles, black carbon, and the elemental composition of PM 2.5 . Sampling over three weeks was conducted in summer and winter for each city and covered each system on a daily basis. Mixed-effect linear regression models were used to identify system features related to particulate exposures. Ambient levels of PM 2.5 and its elemental components were compared to those of the metro in each city. A microenvironmental exposure model was used to estimate the contribution of a 70 min metro commute to daily mean exposure to PM 2.5 elemental and mass concentrations. Time spent in the metro was estimated to contribute the majority of daily exposure to several metallic elements of PM 2.5 and 21.2%, 11.3% and 11.5% of daily PM 2.5 exposure in Toronto, Montreal, and Vancouver, respectively. Findings suggest that particle air pollutant levels in Canadian metros are substantially impacted by the systems themselves, are highly enriched in steel-based elements, and can contribute a large portion of PM 2.5 and its elemental components to a metro commuter's daily exposure.

    The built environment and social cohesion are increasingly recognized as being associated with older adults' quality of life (QoL). However, limited research in this area still exists and the relationship has remained unexplored in the area of Metro Vancouver, Canada. This study examined the association between the built environment and social cohesion with QoL of 160 community-dwelling older adults (aged ≥ 65 years) on low income from Metro Vancouver. Cross-sectional data acquired from the Walk the Talk (WTT) study were used. Health-related QoL (HRQoL) and capability wellbeing were assessed using the EQ-5D-5L and the ICECAP-O, respectively. Measures of the environment comprised the NEWS-A (perceived built environment measure), the Street Smart Walk Score (objective built environment measure), and the SC-5PT (a measure of social cohesion). The primary analysis consists of Tobit regression models to explore the associations between environmental features and HRQoL as well as capability wellbeing. Key findings indicate that after adjusting for covariates, older adults' capability wellbeing was associated with street connectivity and social cohesion, while no statistically significant associations were found between environmental factors and HRQoL. Our results should be considered as hypothesis-generating and need confirmation in a larger longitudinal study. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Three prominent urban rivers in Metro Cebu were samples and analysed for their physico-chemical properties and their toxicity as to surfactant levels was evaluated using tilapia (Oreochromis niloticus L.). Surfactants in rivers, particularly the linear alkylbenzene sulfonates (LAS), ammonia (NH 3 ), nitrate, nitrite and phosphate were determined colorimetrically using UV-Vis spectrophotometer. Physical parameters such as conductivity, salinity, temperature, pH and Dissolved Oxygen (DO) were determined in situ using a Multi-probe digital meter. Winkler Method was carried out to confirm the levels of DO in water samples. Results revealed that Guadalupe, Mahiga and Butuanon Downstream contain DO levels lower than 5 ppm, which is level needed to support aquatic life. This result further correlates the levels of NH 3 in the samples with Guadalupe containing the highest NH 3 level of 13.09 ppm, followed by, Butuanon Dowstream (8.20 ppm), Mahiga (5.95ppm) and Butuanon Upstream (1.22 ppm) which are all beyond the DENR standard limit of 0.5 ppm. The LAS levels were found high in Butuanon Downstream (3.35 ppm), Guadalupe River (1.51 ppm), followed by Mahiga (1.02 ppm), and Butuanon Upstream (0.42 ppm). All of the river water samples except for Butuanon Upstream were beyond the tolerable limit for surfactants as prescribed by the DENR for surface water which is 0.5 ppm. Nitrate and nitrite levels for all river samples were below the DEBR standard limit of 10.0 ppm. Only Guadalupe (0.91 ppm) and Mahiga (0.52 ppm) failed to meet the DENR standard of 0.4 ppm for phosphate. Definitive Test for toxicity of LAS to Tilapia juveniles after 96 h showed an LC 5 0 of 7.6 ppm. This result was used for risk assessment of the three river systems for LAS. Toxicity Test of river samples showed 100% mortality for Guadalupe, Mahiga and Butuanon Downstream. Predicted Environment Concentrations (PEC) to Predicted No Effect Concentration (PNEC) ratio revealed that all river systems were at

    A storm surge is the sudden rise of sea water over the astronomical tides, generated by an approaching storm. This event poses a major threat to the Philippine coastal areas, as manifested by Typhoon Haiyan on 8 November 2013. This hydro-meteorological hazard is one of the main reasons for the high number of casualties due to the typhoon, with 6300 deaths. It became evident that the need to develop a storm surge inundation map is of utmost importance. To develop these maps, the Nationwide Operational Assessment of Hazards under the Department of Science and Technology (DOST-Project NOAH) simulated historical tropical cyclones that entered the Philippine Area of Responsibility. The Japan Meteorological Agency storm surge model was used to simulate storm surge heights. The frequency distribution of the maximum storm surge heights was calculated using simulation results of tropical cyclones under a specific public storm warning signal (PSWS) that passed through a particular coastal area. This determines the storm surge height corresponding to a given probability of occurrence. The storm surge heights from the model were added to the maximum astronomical tide data from WXTide software. The team then created maps of inundation for a specific PSWS using the probability of exceedance derived from the frequency distribution. Buildings and other structures were assigned a probability of exceedance depending on their occupancy category, i.e., 1% probability of exceedance for critical facilities, 10% probability of exceedance for special occupancy structures, and 25% for standard occupancy and miscellaneous structures. The maps produced show the storm-surge-vulnerable areas in Metro Manila, illustrated by the flood depth of up to 4 m and extent of up to 6.5 km from the coastline. This information can help local government units in developing early warning systems, disaster preparedness and mitigation plans, vulnerability assessments, risk-sensitive land use plans, shoreline

  10. Occupational fatalities due to electrocutions in the construction industry.

    Janicak, Christopher A

    2008-01-01

    Occupational fatalities due to contact with electricity account for approximately 9% of all deaths in the construction industry and is the fourth leading cause of death in this industry. Differences in the proportions of electrocutions in the construction industry are significantly different from other industries based upon the age of the worker and the source of the electricity. This study found that, in the construction industry, the proportion of occupational fatalities due to contact with electric current is significantly higher for workers in the 16 to 19 years old age group. Contact with overhead power lines occurred more frequently with younger workers, while contact with electric wiring, transformers, and related equipment was found to occur more frequently with older workers. The proportion of fatalities due to this event was also found to account for a significantly greater proportion of fatalities in the construction industry overall. The proportions of electrocution fatalities in the construction industry were found to be significantly higher for younger workers when compared to all other industries. Focusing prevention measures toward younger workers who work near overhead power lines could have a significant impact upon death rates. For older workers, the focus should be on those who work on or near transformers, electrical wiring, and components. Across the construction industry, implementation of effective lockout-tagout programs, and verification of energy isolation, can prevent approximately 125 fatalities per year in the construction industry.

    Full Text Available In the current situation of the shortage of suitable donor organs, heart transplantation from older donors is one of the ways to increase the performance of more heart transplants, particularly, in patients with urgent need of transplantation. While planning a heart transplantation from older donor one should consider increased risk of early cardiac allograft dysfunction, preexisting coronary artery disease, accelerated transplant vasculopathy which may adversely affect early and long-term survival of recipients. Subject to careful selection of donor–recipient pairs, effective prevention and treatment of early cardiac allograft dysfunction, pre-existing atherosclerosis and transplant vasculopathy the early and long-term survival of heart transplant recipients from older donors is comparable to heart transplantation from young donors.

    Full Text Available O excesso de tráfego de máquinas pode causar compactação prejudicial ao desenvolvimento da cultura. Uma das maneiras de se obter um indicativo de compactação é a resistência do solo à penetração (RSP. Assim, desenvolveu-se um penetrômetro eletrônico, seguindo a norma S313.2 ASAE (1998, tendo a haste 0,0095 m de diâmetro e o cone de 30° com 0,01283 m de diâmetro na base. Para o desenvolvimento do penetrômetro, utilizou-se um sistema para aquisição de dados, sensor de distância, sensor de força e barras circulares de aço inox para confecção da haste e do cone. O aparelho armazena os dados coletados a campo em uma frequência de 4 Hz, sendo estes posteriormente transferidos para um microcomputador, via interface RS232. Por meio de uma planilha eletrônica, os dados podem ser processados de acordo com a necessidade do usuário. Os sensores apresentaram confiabilidade em sua utilização, os arquivos de dados gerados pelo aparelhoproporcionaram conforto e confiança no processamento de dados e os dados puderam ser reorganizados conforme a necessidade do usuário para, assim, evitar o erro de leitura pelo processo visual.Excess machine traffic can cause compaction that is harmful for crop growth. One way to obtain evidence of soil compaction is to check the mechanical resistance of soil. Thus, an electronic penetrometer was developed according to ASAE (1998 Standard S313.2, featuring a 9.53mm wide diving shaft and a 30° circular stainless steel cone with a 12.83 mm base diameter. The penetrometer was outfitted with a data acquisition system, distance and force sensors, and stainless steel circular bars to construct the diving shaft and cone. The device stores field data collected at a frequency of 4 Hz, which are later transferred onto a microcomputer via a RS232 interface. The collected data can be processed using an electronic spreadsheet according to user needs. The sensors proved reliable during use, and the data files

    Full Text Available O ensaio de consolidação preconiza a utilização de um consolidômetro. Esse equipamento, até então, não era produzido e comercializado no Brasil. Os modelos não automatizados disponíveis para importação, apesar da proposta de baixo custo, ainda são rústicos e necessitam de contínua calibração dos níveis de pressão durante a realização do ensaio. A exclusividade e intervenção de um técnico durante todo o ensaio, associada à precária coleta de dados nesses modelos, ainda são os principais fatores que têm inviabilizado a consolidação desse ensaio na ciência do solo brasileira. Como alternativa a esses problemas, este trabalho teve por objetivos desenvolver e automatizar um consolidômetro a partir de um Controlador Lógico Programável (CLP com interface homem-máquina (IHM. O equipamento é constituído de um gabinete de metal que aloja conjuntos de dispositivos pneumáticos, eletrônico-digital e atuadores de força e posição. O funcionamento de cada dispositivo de forma isolado ou conjugado é gerenciado por meio de um software em linguagem de programação ladder, que, a partir de um CLP com IHM incorporada, possibilita armazenar instruções e implementar funções. A interface entre o PC e o consolidômetro é feita pelo software CA-Linker, v 1.0, projetado especificamente para o equipamento. O uso do CLP com IHM incorporada permitiu o desenvolvimento e a automação do consolidômetro. O desempenho e a eficiência do conjunto de dispositivos (pneumáticos, eletrônico-digital e atuadores de força e pressão foram comprovados pelos excelentes resultados dos valores de deformação e pressão obtidos em função do tempo e, principalmente, do comportamento da curva de compressão, gerada pelos ensaios de compressão.

Reference school requires all staffs to manage and organize the school establishment in accordance with quality management procedure and do their best to improve their competency and qualification. The improvement of their competency and qualification is a supporting factor of the service provided by the school to all stake holders at SMKN 2 Metro. The aim of the research is to improve the performance of the staff at SMKN 2 Metro.It was school action research applied. This research was conducted to improve working situation and process to overcome problems of the school. SMKN 2 Metro is located at Street Yos Sudars, West Metro of Metro Municipal City. The subjcts of the research were staff consist of 13 civil servants (PNS and 20 volunteer (PTT. It was done for three months from February to April 2015.The researcher was able to conclude that staff performance at SMKN 2 Metro improved when variation of leadership approach applied. This conclusion was supported by some findings. There was linear improvement of staff performance both PNS and PTT. The improvement of PTT performance was better than PNS in the beggining of the treatment, bu then they reached the same quality of improvement. Coersive power needed to be apllied more intensive in the beggining although applied with very careful manner. Flexible leadership approach must equip authoritative approach.

  8. Impression Management in the Job Interview: An Effective Way of Mitigating Discrimination against Older Applicants?

    Science.gov (United States)

    Gioaba, Irina; Krings, Franciska

    2017-01-01

    The increasingly aging population in most industrialized societies, coupled with the rather age-diverse current workforce makes discrimination against older employees a prevalent issue, especially in employment contexts. This renders research on ways for reducing this type of discrimination a particularly pressing concern. Drawing on theories of social identity and impression management, our research examines the role of impression management, aimed at refuting common older worker stereotypes, in diminishing bias against older job applicants during the job interview. The study consisted in an experimental hiring simulation conducted on a sample of 515 undergraduate students. Results show that older applicants who used impression management to contradict common older worker stereotypes were perceived as more hirable than those who did not. However, despite this positive effect, discrimination persisted: older applicants were consistently rated as less hirable than their younger counterparts when displaying the same IM behavior. Taken together, this research demonstrates that older job seekers can indeed ameliorate biased interview outcomes by engaging in impression management targeting common age stereotypes; however, it also shows that this strategy is insufficient for overcoming age discrimination entirely. The current study has important implications for theory, by expanding research on the use of impression management in mitigating age discrimination, as well as for practice, by offering older employees a hands-on strategy to reduce bias and stereotyping against them.

    2008-12-01

    This article examined social issues surrounding casino gambling among older adults both nationally and in the state of North Dakota. An exploratory review of gambling trends among older adults and an examination of policies to protect older gamblers revealed that older adults are targeted by the gaming industry as a lucrative market (Singh et al. J Retail Leisure Property 2007, 6(1):61-68). The authors used the national literature to frame their qualitative study, which explored gambling issues among older adults in North Dakota from the perspective of six counselors trained in gambling addiction who provide treatment services in the state. Findings indicated that relatively few policies existed at the state and national levels to protect older, more vulnerable adults who gamble. Further, the six casinos in North Dakota were viewed as very effective in marketing their casino gaming opportunities to older citizens by the gambling treatment providers interviewed. Additionally, barriers to gambling addiction treatment involved lack of available services and distance to receive services in this rural state. Based on the findings of this study, social policy changes which could lead to increased protection for older adult gamblers in the state were included.

    Sexuality is an important part of a person's life continuing into older age. Physiologic changes that occur with aging can affect sexual function and may be exacerbated by comorbid disease. To diagnose sexual dysfunction, providers must obtain a thorough history and physical examination, including psychosocial factors. The causes of sexual dysfunction along with patient preferences within the patient's social system serve as the foundation for developing person-centered strategies to address these concerns. To improve care of older adults with sexual concerns, providers should initiate discussions with, listen to, and work with patients to create a comprehensive management plan.

    Impaired wound healing in the elderly represents a major clinical problem that is growing as our population ages. Wound healing is affected by age and by co-morbid conditions, particularly diabetes and obesity. This is particularly important in Rhode Island as the state has a very high percentage of vulnerable older adults. A multi- disciplinary approach that incorporates the skills of a comprehensive wound center with specialized nursing, geriatric medicine and palliative care will facilitate rapid wound healing, reduce costs and improve outcomes for our older adults that suffer from 'problem wounds'.

    Leisure activities contribute to well-being and health in old age. Community nurses should consequently promote such activities among older persons. To do so they need an understanding of older persons' interest in leisure activities. Social contacts, volunteering and pursuit of hobbies and interests constitute the main aspects of leisure. This study aimed to determine the attitudes of older Germans to these aspects to identify user types of leisure time facilities. A qualitative study was conducted within a community-based project in an industrial town in West Germany. Data were collected with semi-structured guideline interviews and evaluated with qualitative content analysis according to Mayring. With regard to social contacts attitudes ranged from limited need for contacts to being a reliable member in an older persons' club. Social engagement is only found among the latter. Pursuit of hobbies and interest ranged from being a minimal user of leisure time facilities to refined expectations. Inflexible group structures may prevent potential users from participation despite having a programme in accordance with target group needs. Attitudes to leisure activities can be described as a combination of two dimensions: the degree of social involvement and the desired refinement of hobbies and interest. Community nurses who organise social afternoons need to assess these attitudes and should steer social dynamics of in a way that facilitates access for newcomers. © 2012 Blackwell Publishing Ltd.

    2015-12-01

    Storm surge is the abnormal rise in sea water over and above astronomical tides due to a forthcoming storm. Developing an early warning system for storm surges is vital due to the high level of hazard they might cause. On 08 November 2013, Typhoon Haiyan generated storm surges that killed over 6,000 people in the central part of the Philippines. The Nationwide Operational Assessment of Hazards under the Department of Science and Technology was tasked to create storm surge hazard maps for the country's coastal areas. The research project aims to generate storm surge hazard maps that can be used for disaster mitigation and planning. As part of the research, the team explored a scenario wherein a tropical cyclone hits the Metro Manila with strength as strong as Typhoon Haiyan. The area was chosen primarily for its political, economic and cultural significance as the country's capital. Using Japan Meteorological Agency Storm Surge model, FLO2D flooding software, LiDAR topographic data, and GIS technology, the effects of a Haiyan-induced tropical cyclone passing through Metro Manila was examined. The population affected, number of affected critical facilities, and potential evacuation sites were identified. The outputs of this study can be used by the authorities as basis for policies that involve disaster risk reduction and management.

    2010-12-01

    The plight of older adults during catastrophic events is a societal concern. Older persons have an increased prevalence of cognitive disorders, chronic illnesses, and mobility problems that limit their ability to cope. These disorders may result in a lack of mental capacity and the ability to discern when they should evacuate or resolve problems encountered during a catastrophe. Some older persons may have limited transportation options, and many of the elderly survivors are at increased risk for abuse, neglect, and exploitation. Recommendations for future catastrophic events include the development of a federal tracking system for elders and other vulnerable adults, the designation of separate shelter areas for elders and other vulnerable adults, and involvement of gerontological professionals in all aspects of emergency preparedness and care delivery, including training of frontline workers. Preparation through preevent planning that includes region-specific social services, medical and public health resources, volunteers, and facilities for elders and vulnerable adults is critical. Elders need to be protected from abuse and fraud during catastrophic events. A public health triage system for elders and other vulnerable populations in pre- and postdisaster situations is useful, and disaster preparedness is paramount. Communities and members of safety and rescue teams must address ethical issues before an event. When older adults are involved, consideration needs to be given to triage decision making, transporting those who are immobile, the care of older adults who receive palliative care, and the equitable distribution of resources. Nurses are perfectly equipped with the skills, knowledge, and training needed to plan and implement disaster preparedness programs. In keeping with the tradition of Florence Nightingale, nurses can assume several crucial roles in disaster preparedness for older adults. Nurses possess the ability to participate and lead community

    Full Text Available Introduction: The aging population is a rapidly growing demographic in the United States. Isolation, limited autonomy, and declining physical and mental health render many older adults vulnerable to elder mistreatment (EM. The purpose of this study was to assess the prevalence and correlates of EM among a sample of older adults using legal assistance services in Atlanta, Georgia.Methods: Researchers administered surveys to consenting older adults (aged 60þ in 5 metro Atlanta community centers that hosted legal assistance information sessions as part of the Elderly Legal Assistance Program. The surveys screened for risk factors and prevalence of EM risk using valid and reliable measures and included additional questions regarding demographics characteristics and healthcare use behaviors.Results: Surveys were completed by 112 participants. Findings reveal that 32 (28.6% respondents met the criteria for elder abuse / neglect risk; 17 (15.2% respondents met criteria for depression; and 105 (93.7% had visited a healthcare provider during the past 6 months.Conclusion: The rates of EM risk in this sample were higher than those previously reported in research. Findings support continued examination of unique risks that may be present among older adults who may be possibly facing legal issues. Additionally, the reported frequency of healthcare visits among participants reveals a promising opportunity to examine development of a more widespread EM screening approach to be conducted in non-emergency settings. Interdisciplinary collaboration is required to inform screening approaches that account for complexities that EM cases present. [West J Emerg Med. 2013;14(4:309–315.

    Many OECD countries have, or have had, a policy that exempts older unemployed people from the requirement to search for a job. An aging population and low participation by older workers in the labor market increasingly place public finances under strain, and spur calls for policy measures that activate labor force participation by older workers. Introducing job search requirements for the older unemployed aims to increase their re-employment rates. Abolishing the exemption from job search req...

    The domestic petroleum industry faced with outward opening and exchange crisis is put under the most difficult period so far, and costs reduction and securing international competitive power in software field are emerging as important assignments on which the life and death of national key industries depends not only as a restructuring issue of each petroleum company. Required strategy of petroleum industry to solve this effectively this year must be the thorough revamping through restructuring and reform of management standards not the survival exercise through price competition. For this, each petroleum company and distributor should open a new petroleum industry in which fair rules of the game are developed as well as costs reduction through joint efforts and value creation in overall industry. For this, government should support the domestic petroleum industry to stand up straight as a keeper of domestic energy industry by helping it to arm with international competitive power within a short period of time through overall needed system and legal scheme. It is because nobody can deny that energy industry is the key industry on which national existence is at stake.

  6. Prelude to a RIF: older workers, part-time hours, and unemployment.

    Reynolds, Jeremy; Wenger, Jeffrey B

    2010-04-01

    Since the beginning of the most recent recession in December 2007, involuntary part-time employment (part-time for economic reasons) in the United States has increased from 4.2 million workers to 9.1 million, more than doubling. In this paper, we examine whether such increases in involuntary part-time employment have helped combat unemployment in the past or placed a disproportionate burden on older workers. Using Current Population Survey (outgoing rotation group) data from 1983 to 2002, we find that increases in involuntary part-time work in an industry raise the industry unemployment rate. Furthermore, the connection between rising rates of involuntary part-time work and unemployment is stronger among older workers than among younger workers. We conclude that reducing work hours through the use of part-time work does not ameliorate the effects of recessions on workers. Rather, it is a harbinger of unemployment, especially among those older than 55.

    The positive effect of physical activity in the prevention and treatment of many chronic diseases and age-related disabilities, such as mobility-disability, are widely accepted. Mobility is broadly defined as the ability of individuals to move themselves within community environments. These two concepts -physical activity and mobility - are closely linked and together contribute to older adults living healthy, independent lives. Neighborhood destinations may encourage mobility, as older adults typically leave their homes to travel to specific destinations. Thus, neighborhoods with a high prevalence of destinations may provide older adults an attractive opportunity to walk, instead of drive, and thereby obtain incidental physical activity. We know surprisingly little about the specific types of destinations older adults deem relevant and even less about destinations that support the mobility of older adults with low income. Accessible neighborhood destinations may be especially important to older adults with low income as they are more likely to walk as a primary travel mode. Conversely, this population may also be at increased risk of functional impairments that negatively affect their ability to walk. As a means to fill this information gap we aimed to better understand the mobility habits of older adults with low income. Thus, our specific objectives were to: (1) describe the types of destinations older adults with low income most commonly travel to in one week; and (2) determine the association between the prevalence of neighborhood destinations and the number of transportation walking trips these individuals make (average per day). We conducted a cross-sectional study of community-dwelling older adults with low income residing within Metro Vancouver, Canada. We assessed participant travel behavior (frequency, purpose, mode, destination) using seven-day travel diaries and measured the prevalence of neighborhood destinations using the Street Smart Walk Score.

  8. Cancer and reproductive risks in the semiconductor industry.

    2007-01-01

    Although many reproductive toxicants and carcinogens are used in the manufacture of semiconductor chips, and worrisome findings have been reported, no broad epidemiologic study has been conducted to define possible risks in a comprehensive way. With few exceptions, the American semiconductor industry has not supported access for independent studies. Older technologies are exported to newly industrialized countries as newer technologies are installed in Japan, the United States, and Europe. Thus there is particular concern about the many workers, mostly in countries that are still industrializing, who have jobs that use chemicals, technologies, and equipment that are no longer in use in developed countries. Since most countries lack cancer registries and have inadequate reproductive and cancer reporting mechanisms, industry efforts to control exposures to carcinogens are of particular importance. Government agencies, the courts, industry, publishers, and academia, on occasion, collude to ignore or to downplay the importance of occupational diseases. Examples of how this happens in the semiconductor industry are presented.

    RESUMEN

    En el estudio de la estructura temporal de un deporte el primer factor de análisis es el volumen total de trabajo que tiene esa actividad o competición, normalmente reflejado en los juegos deportivos a través del tiempo total de actividad, completado por el tiempo real de juego, y el tiempo de actuación y pausa, como parámetros temporales representativos de la duración de la jugada y del tiempo que transcurre entre ellas, siendo indicativos del esfuerzo y recuperación media del partido. El presente estudio, trata de establecer las diferencias existentes entre el individual masculino y femenino, y los diferentes grupos de nivel nacional (jugadores de las selecciones españolas e internacional (los mejores jugadores del mundo. Los datos de tiempo total en relación a la modalidad y los diferentes grupos de nivel muestran valores mayores en todos los grupos para el individual masculino, explicado por la diferente puntuación, exceptuando el caso del campeonato del mundo. Mientras que en las cuatro competiciones de menor nivel el tiempo de actuación medio en individual masculino fue superior al de individual femenino en más de un segundo, con una media en los partidos de individual masculino de 7,3 1,3 seg., y en los partidos de individual femenino de 6,3 1,3 seg. Según los datos obtenidos en relación a la estructura temporal y teniendo en cuenta el volumen e intensidad de las acciones de juego, podemos sugerir que el bádminton está basado en esfuerzos de tipo explosivo con predominancia del metabolismo de los fosfágenos (ATP y PC, existiendo una gran solicitación de la vía anaeróbica aláctica, 90-95% del total de jugadas, y en menor porcentaje del metabolismo anaeróbico láctico, que dependerá en gran medida de la duración y número de jugadas.

En este estudio se utiliza una versión modificada de un modelo de espacio de estados en tiempo real discreto, que considera los efectos de saturación en la línea de metro. Una vez que el modelo de espacio de estados se ha obtenido, el método directo de Lyapunov se aplica con el fin de analizar la estabilidad del sistema de la línea de metro. Como resultado de este análisis no sólo se propone un nuevo índice de estabilidad, sino también la creación de tres zonas de estabilidad para indicar el estado actual del sistema. Finalmente, se presenta un nuevo algoritmo que permite la reprogramación del calendario de los trenes en tiempo real en presencia de perturbaciones medianas. Abstract: A new Lyapunov-based index for designing a rescheduling algorithm in real time for metro lines has been proposed in this paper. A modified real time discrete space state model which considers saturation effects in the metro line has been utilized in this study. Once the space state model has been obtained, the direct method of Lyapunov is applied in order to analyze the stability of the metro line system. As a result of this analysis not only a new stability index is proposed, but also the establishment of three stability zones to indicate the current state of the system. Finally, a new algorithm which allows the rescheduling of the timetable in the real time of the trains under presence of medium disturbances has been presented.

It is an important aspect of quality of life which is often neglected by people in this age group, attending physicians and the society as a whole. The study was aimed at determining the perception of older adults about sexuality, identify the factors that could militate against sexuality and fill any void in information in this regard. Methods Descriptive study conducted in one hundred older adults. A semi-structured questionnaire was administered to consenting participants between 1st of September 2013 and 31st of March 2014. Results Mean age of respondents was 66.42± 5.77 years. Seventy-eight percent of the male respondents considered engaging in sexual activity as safe compared to 45.8% of the female respondents. More of the women (33.3%) regarded sexuality in the older adults as a taboo when compared to the men (5.4%). However, the men were more favourably disposed to discussing sexual problems than the women with their spouses (42% vs 20%) and Physicians (23.2% vs 0.0%). Major factors responsible for sexual inactivity were participants’ medical ailments (65%), partners’ failing health (15%) as well as anxiety about sexual performance (25%) in the men and dyspareunia (25%) in women. Conclusion There is an urgent need to correct the misconception about sexuality in this age group especially among the women and for the physicians to explore the sexual history of every patient.

    Oftentimes the older adults are assumed to be asexual as few studies explore into the sexuality of this age group worldwide and even in Nigeria. It is an important aspect of quality of life which is often neglected by people in this age group, attending physicians and the society as a whole. The study was aimed at determining the perception of older adults about sexuality, identify the factors that could militate against sexuality and fill any void in information in this regard. Descriptive study conducted in one hundred older adults. A semi-structured questionnaire was administered to consenting participants between 1(st) of September 2013 and 31(st) of March 2014. Mean age of respondents was 66.42 ± 5.77 years. Seventy-eight percent of the male respondents considered engaging in sexual activity as safe compared to 45.8% of the female respondents.

    Fine resolution spatial variability in pneumonia hospitalization may identify correlates with socioeconomic, demographic and environmental factors. We performed a retrospective study within the Fairview Health System network of Minnesota. Patients 2 months of age and older hospitalized with pneumonia between 2011 and 2015 were geocoded to their census block group, and pneumonia hospitalization risk was analyzed in relation to socioeconomic, demographic and environmental factors. Spatial analyses were performed using Esri's ArcGIS software, and multivariate Poisson regression was used. Hospital encounters of 17 840 patients were included in the analysis. Multivariate Poisson regression identified several significant associations, including a 40% increased risk of pneumonia hospitalization among census block groups with large, compared with small, populations of ⩾65 years, a 56% increased risk among census block groups in the bottom (first) quartile of median household income compared to the top (fourth) quartile, a 44% higher risk in the fourth quartile of average nitrogen dioxide emissions compared with the first quartile, and a 47% higher risk in the fourth quartile of average annual solar insolation compared to the first quartile. After adjusting for income, moving from the first to the second quartile of the race/ethnic diversity index resulted in a 21% significantly increased risk of pneumonia hospitalization. In conclusion, the risk of pneumonia hospitalization at the census-block level is associated with age, income, race/ethnic diversity index, air quality, and solar insolation, and varies by region-specific factors. Identifying correlates using fine spatial analysis provides opportunities for targeted prevention and control.

    Eating disorders (EDs) are disturbances that seriously endanger the physical health and often the lives of sufferers and affect their psychosocial functioning. EDs are usually thought of as problems afflicting teenagers. However, the incidence in older women has increased in recent decades. These cases may represent either late-onset disease or, more likely, a continuation of a lifelong disorder. The DSM-5 classification differentiates 4 categories of eating disorder: anorexia nervosa, bulimia nervosa, binge-eating disorders and other specified feeding and eating disorders. The weight loss and malnutrition resulting from EDs have widespread negative consequences for physical, mental and social health. The main risk factors for developing long-term consequences are the degree of weight loss and the chronicity of the illness. Most of the cardiac, neurological, pulmonary, gastric, haematological and dermatological complications of EDs are reversible with weight restoration. EDs are serious illnesses and they should never be neglected or treated only as a manifestation of the fashion for dieting or a woman's wish to achieve an imposed standard feminine figure. Additionally, EDs are associated with high risk of morbidity and mortality. The literature concerning EDs in older, postmenopausal women is very limited. The main aim of this paper is to ascertain the epidemiology and prognosis of EDs in older women, and to review their diagnosis and management. Copyright © 2015 Elsevier Ireland Ltd.

    Full Text Available The aging of the labor force is observed in most developed and developing countries. The employment rate of older employees has been increasing every year and it appears to be not changed in the nearest future. The aging workforce is a serious challenge for organizations due to the prevailing stereotypical approach that older employees are less motivated, demonstrate lower labor productivity, they have more difficulties adopting new information, technologies and the lower ability to adapt to innovations. The aim of the paper is to investigate the impact of the work characteristics on the involvement in the work, the influence of employee’s characteristics on the work engagement, the influence of age and related factors on the involvement in the work and the relationship between age and achievements. The research is based on the analysis and synthesis of scientific literature, investigating to reveal the diversity of the concepts and methodologies and to systematize prevailing issues. The paper integrates the main researches in the field of older employees’ engagement and provides recommendations for future research.

  7. Older men, work and health.

    2010-05-01

    To consider the complex interrelationships between work and health among older men, drawing out the importance of considering gender difference in approaches to occupational medicine. The method used in the literature search was to review national and international research published in English since 1990 on the health and work of older men. Journal articles were the primary source. Databases used included Web of Science, CSA Illumina Social Sciences, CINAHL, Medline and ANGINFO. The review of the evidence was structured in terms of key themes emerging from the literature into which issues of gender, ethnicity, age and socio-economic inequalities were cross cut. The current paper now focuses on two of those themes that have particular relevance to occupational medicine: work-caused and work-related ill-health, and secondly promoting workplace health. It begins by setting the scene with a profile of older men in the labour market. Two key themes emerge from the review, which are of particular significance. One is the central role that work plays in the lives and identity of men and therefore the impact this has on their health, both in and out of work. Secondly, the occupational histories of men expose them to work-related and work-caused ill-health, which has consequences for life expectancy and chronic disease in old age. These findings have implications for future research, policy formulation and implementation, and for public health practice.

  8. Preventing Falls in Older Persons.

    2017-08-15

    The American Geriatrics Society and British Geriatrics Society recommend that all adults older than 65 years be screened annually for a history of falls or balance impairment. The U.S. Preventive Services Task Force and American Academy of Family Physicians recommend exercise or physical therapy and vitamin D supplementation to prevent falls in community-dwelling older adults who are at increased risk of falls. Although the U.S. Preventive Services Task Force and American Academy of Family Physicians do not recommend routine multifactorial intervention to prevent falls in all community-dwelling older adults, they state that it may be appropriate in individual cases. The Centers for Disease Control and Prevention developed an algorithm to aid in the implementation of the American Geriatrics Society/British Geriatrics Society guideline. The algorithm suggests assessment and multifactorial intervention for those who have had two or more falls or one fall-related injury. Multifactorial interventions should include exercise, particularly balance, strength, and gait training; vitamin D supplementation with or without calcium; management of medications, especially psychoactive medications; home environment modification; and management of postural hypotension, vision problems, foot problems, and footwear. These interventions effectively decrease falls in the community, hospital, and nursing home settings. Fall prevention is reimbursed as part of the Medicare Annual Wellness Visit.

  9. Dry mouth and older people.

    Thomson, W M

    2015-03-01

    Dry mouth is more common among older people than in any other age group. Appropriate definition and accurate measurement of dry mouth is critical for better understanding, monitoring and treatment of the condition. Xerostomia is the symptom(s) of dry mouth; it can be measured using methods ranging from single questions to multi-item summated rating scales. Low salivary flow (known as salivary gland hypofunction, or SGH) must be determined by measuring that flow. The relationship between SGH and xerostomia is not straightforward, but both conditions are common among older people, and they affect sufferers' day-to-day lives in important ways. The major risk factor for dry mouth is the taking of particular medications, and older people take more of those than any other age group, not only for symptomatic relief of various age-associated chronic diseases, but also in order to reduce the likelihood of complications which may arise from those conditions. The greater the number taken, the greater the associated anticholinergic burden, and the more likely it is that the individual will suffer from dry mouth. Since treating dry mouth is such a challenge for clinicians, there is a need for dentists, doctors and pharmacists to work together to prevent it occurring. © 2015 Australian Dental Association.

  10. Industrial initiatives in the wind industry

    Edworthy, J.

    1992-01-01

    Industrial initiatives are methods of lobbying and marketing to increase the activity, revenues, profits, and commercial viability of an industry. They may be undertaken by industry individuals or firms, industry groups, government agencies, or combinations of all these. In Canada, one example of an industrial initiative is the Canadian Wind Energy Association. Other initiatives relevant to the wind power industry include Technology Inflow Programs sponsored by External Affairs Canada, used for visiting foreign firms with the view to licensing foreign technology, and Industrial Research Assistance Programs to develop or adapt new technologies in partnership with government. The Conservation/Renewable Energy Council, Small Power Producers of Alberta, and Independent Power Producers Society of Ontario are also active in supporting wind energy initiatives. In other countries, notable initiatives for wind energy include the Danish wind turbine warranty guarantee program. The Western Wind Industry Network of Canada conducts regional lobbying. It is suggested that in Canada, more such networks are needed, as well as joint ventures with utilities and governments, and more work with the regulatory agencies, to promote wind energy

    Attitude of healthcare providers toward older people is very important in the aging world. Neurologists contact older adults very frequently. We aimed to investigate the attitudes of neurologists toward older adults. We recorded participants age; sex; duration of clinical practice in neurology; existence of older adult relatives; and history of geriatrics education, nursing home visits, older adult patient density in their clinical practice, and participation in voluntary public activities. UCLA Geriatrics Attitude Scale was used to evaluate participants' attitudes. A total of 100 neurologists participated in this study. Seventy-seven percent had positive, 3 % had neutral, and 20 % had negative attitudes. Twenty-seven percent of the participants had history of geriatrics education, and these participants tended to have a higher rate of positive attitudes. Neurologists with positive attitudes tended to be older than those with negative attitudes. Participants with history of living with older adult relatives had lower rates of positive attitudes. The most common diagnoses of the patients the participants encountered were stroke and dementia. Independent factors associated with positive attitudes were history of geriatrics education and older age. History of living with older relatives tended to have a negative effect. Most of the negative items of the attitude scale were associated with the natural course and behavior of the common diseases in neurology practice. Generalization of geriatrics education may translate into a better understanding and improved care for older patients. Development of instruments and implementation of qualitative studies to assess attitudes of neurologists toward older adults are needed.

    To describe the nutritional status in older adults and its association with sociodemographic characteristics. A cross-sectional study was conducted. Sampling was probabilistic, stratifi and multistage. Nutritional status was assessed by body mass index (BMI) according to the classifi of nutritional status for the elderly from the Ministry of Health of Peru. The statistical analysis considered the necessary weight for complex samples. The study included 7,267 older adults. 26.8% of participants were underweight, 21.7% overweight, 10.6% obese and 40.8% normal. The average age in the sample was 70.1 ± 8.3 years. Illiteracy (OR 1.9; 95% CI 1.2-3.0), primary education (OR 1.9; 95% CI 1.3-2.9), extreme poverty (OR 2.0; 95% CI 1.6-2.5), living in rural areas (OR 1.8; 95% CI 1.5-2.1), living in the mountains (OR 1.6; 95% CI 1.2-2.2) or jungle (OR 1.6; 95% CI 1.1-2.2) were found associated with underweight. Females (OR 1.8; 95% CI 1.4-2.1), living in urban areas (OR 2.0; 95% CI 1.6-2.5), living in the coastal region (OR 1.5; 95% CI 1.2- 1.8); and not classifi as poor (OR 1.9; 95% CI 1.3-2.9) were associated with overweight. Female sex (OR 3.1; 95% CI 2.3-4.1), primary education (OR 2.4; 95% CI 1.5-4.0) and secondary (OR 2.0; 95% CI 1.2-3.4); live in urban areas (OR 2.2; 95% CI 1.6-2.9), inhabiting the coast (OR 1.8; 95% CI 1.3-2.4), Metro (OR 1.6, 95% CI 1.1-2.2) and jungle (OR 1.6; 95% CI 1.1-2.2), and not classifi as poor (OR 3.5; 95% CI 1.8-7.0) were associated with obesity. The data suggest that both underweight and overweight are common in the elderly population studied.

    The relationship to age of irrational beliefs among psychiatric inpatients has not been explored using the rational-emotive model. This study addressed the following two questions: 1) Do older and younger psychiatric inpatients differ in irrational beliefs? 2) Do older depressives differ from older nondepressives in irrational beliefs? Upon admission to a large medical center, 58 younger (less than 45 years old) and 54 older (greater than 55 years old) subjects were assessed on a battery of psychological tests, including the Idea Inventory and the Beck Depression Inventory. Results showed that older and younger inpatients did not differ on irrational beliefs. Results also showed that older and younger groups of depressives did not differ on the irrationality scores. When a correlational analysis was used, depression was related to irrationality within the older group but not within the younger group.

    Recent research has expanded our understanding of sexual homicide offenders (SHOs). However, little exists beyond case reports for older SHOs. We characterized male SHOs ≥ 55 years, comparing them to typical adult male SHOs who are in their 20s. Analysis of 37 years (1976-2012) of US Supplementary Homicide Reports data provided a large SHO sample (N = 3453). Three case reports provide clinical context for the diverse nature and patterns of older SHOs. Only 32 older male SHOs and no older female SHOs were identified. Murders by older SHOs accounted for only 0.5% of US sexual homicides. Unlike typical SHOs that generally target young adult females, over two-thirds of older SHO victims were ≥40 years, and one-third were ≥55 years. Sexual homicides by older SHOs, like sexual homicide in general, decreased over the study period. These crimes, while exceedingly rare, do occur, warranting special consideration. © 2017 American Academy of Forensic Sciences.

    Full Text Available High-power electrical drives, subsystems, and equipment mounted on board of rolling stock make the internal environment potentially harsh from the point of view of electromagnetic (EM field emissions. In particular, at low frequencies, electronically controlled power drive systems behave as effective emission sources. This paper deals with characterization of electromagnetic field radiated from D.C. railway systems. The D.C. railway system of Tunis’s urban electric metro is described. The magnetic field is measured at different points inside and near the moving D.C. train. Measurement results are presented and analyzed. Analysis of measurement results shows that, within frequency range 100kHz-20MHz, the radiated magnetic field is coming from power electronic systems embedded on the train. In particular, choppers, D.C. motors and their connecting cables represent the most important emitting source of magnetic field in the D.C. tramway.

    MetroBeta is a European project aiming at the improvement of the knowledge of the shapes of beta spectra, both in terms of theoretical calculations and measurements. It is part of a common European program of ionizing radiation metrology. Metallic magnetic calorimeters (MMCs) with the beta emitter embedded in the absorber have in the past proven to be among the best beta spectrometers, in particular for low-energy beta transitions. Within this project, new designs of MMCs optimized for five different beta energy ranges were developed. A new detector module with thermal decoupling of MMC and SQUID chips was designed. An important aspect of the research and development concerns the source/absorber preparation techniques. Four beta spectra with maximum energies ranging from 76 to 709 keV will be measured. Improved theoretical calculation methods and complementary measurement techniques complete the project.

Data was obtained through a survey of 400 households in Marikina City in Metro Manila, Philippines. Results from the empirical analysis indicated that household income, access to credit (borrowing, the use of a flood alarm system, access to safe shelter, membership in a community organisation, adoption of disaster-specific anticipatory measures and adoption of general preventive measures significantly reduced the time it took for affected households to recover from property damage. Evacuation, relief aid, type of housing, education, household size and frequency of flooding in the area did not have significant effects.

    2014-01-01

    Rainfall is a key link in the global water cycle and a proxy for changing climate; therefore, proper assessment of the urban environment's impact on rainfall will be increasingly important in ongoing climate diagnostics and prediction. Aerosol optical depth (AOD) measurements on the monsoon seasons of the years 2008 to 2010 were made over four metro regional hotspots in India. The highest average of AOD was in the months of June and July for the four cities during 3 years and lowest was in September. Comparing the four regions, Kolkata was in the peak of aerosol contamination and Chennai was in least. Pearson correlation was made between AOD with climatic parameters. Some changes in the parameters were found during drought year. Temperature, cloud parameters, and humidity play an important role for the drought conditions. The role of aerosols, meteorological parameters, and their impacts towards the precipitation during the monsoon was studied.

From November 2009 to January 2010, an HIV testing booth was set up adjacent to bars and restaurants in Metro Manila frequented by MSM at night. Participants aged > or =18 years were interviewed using a structured questionnaire. Rapid HIV antibody screening was performed using SD Bioline HIV 1/2 3.0 (Standard Diagnostics). Of 406 MSM included in the study, the mean age was 26.2 years [standard deviation (SD) 5.4]; 96% believed condoms reduced HIV risk but only 3% reported consistent use. The leading reasons for not using condoms were belief that the partner was HIV negative (34.4%), diminished pleasure (32%), and unavailability (23.4%). The HIV prevalence using the rapid test was 11.8% [95% confidence interval (CI): 8.7- 15.0]. All 40 cases who had a confirmatory Western blot test were positive, of whom 24 were business process outsourcing employees (BPOEs). On multivariate analysis, work as a BPOE [adjusted OR (aOR): 3.37; p=0.001], preference for receptive anal sex (aOR: 5.26; p=0.04), and sex while under the influence of excessive alcohol (aOR: 2.71; p=0.04) were independently associated with HIV. The proportion of BPOEs who consistently use condoms when having insertive anal sex with a stranger was significantly lower compared to non-BPOEs (24.5% versus 38.2%; p=0.02). Urgent interventions are needed to address the HIV epidemic in the Philippines.

    Full Text Available O objetivo deste trabalho foi avaliar as propriedades e o comportamento de solos aluviais do perímetro irrigado de Custódia, PE, cujo uso agrícola foi interrompido em virtude de problemas de salinidade/sodicidade. Foram realizadas caracterizações morfológica, física, química e mineralógica de três perfis de solos afetados por sais do referido perímetro irrigado. Os solos foram classificados, de acordo com o Sistema Brasileiro de Classificação de Solos, como Neossolo Flúvico Ta eutrófico solódico, Neossolo Flúvico Sódico salino e Neossolo Flúvico Sódico típico. A estratificação, típica de solos de natureza aluvial, rege o comportamento físico e químico dos solos estudados no sentido vertical. Apesar da presença de minerais que podem contribuir com o processo de salinização/sodificação, tal contribuição deve ser irrisória quando comparada à das águas de rega de baixa qualidade. A reutilização destes solos com agricultura irrigada deve ser precedida do uso de corretivos e da introdução de um eficiente sistema de drenagem que impeça a ascensão do lençol freático e promova a lixiviação do sódio.

    Para la construcción mecánica del sistema, se utilizaron perfiles de aluminio de 60x30 mm. Esta estructura metálica sujeta a una fibra óptica de cuarzo lleva la radiación solar al espectrómetro Ocean Optics USB4000 (200-900 nm. La electrónica del sistema de control, está gobernada por un microcontrolador Arduino UNO, el cual se encarga de sincronizar el movimiento de dos motores PAP bipolares y la toma de datos en el espectrómetro que se activa con un trigger externo. La característica principal del sistema es permitir la medición del espectro de los componentes global y difuso de la radiación solar en diferentes ángulos de incidencia. El sistema mecánico ajusta un extremo de una fibra óptica de 0 a 90 grados en dirección norte, cada nueve grados, midiendo la radiación global y mediante una banda mecánica que produce sombra sobre la fibra óptica, mide la radiación difusa. Las medidas son tomadas cada hora y el rango espectral abarcado es del UVA, VIS y parte del IR cercano. Se realizaron pruebas preliminares en dos ciudades de Bolivia y se demostró que la cantidad de radiación UVA es mayor en el El Alto (4062 msnm, la ciudad con mayor elevación, en comparación con Cochabamba que se encuentra a 2570 msnm.

    Full Text Available Introduction: There has been an increasing secular trend in the prevalence of overweight and obesity in developing countries. The prevalence reported among children and adolescents of some metro cities in India are comparable to that in some developed countries. Westernization of culture, rapid mushrooming of fast food joints, lack of physical activity, and increasing sedentary pursuits in the metro cities are some of the reasons implicated for this. The nutritional changes in small town school children might be following the same pattern of larger cities. Aims and Objectives: To study the prevalence of overweight and obesity among school-going adolescents of Aligarh and to study the sociodemographic and behavioral correlates of the same. Materials and Methods: A cross-sectional study done in two affluent and two nonaffluent schools in Aligarh, taking 330 adolescents from each group (total-660. Study tools included a predesigned and pretested questionnaire, Global Physical Activity Questionnaire, and anthropometric measurement. Overweight and obesity were defined based on World Health Organization 2007 Growth Reference. Chi-square test and multiple logistic regression analysis were done. Results: Prevalence of overweight and obesity was 9.8% and 4.8% among school-going adolescents. The difference in prevalence of overweight and obesity among affluent schools (14.8% and 8.2% and nonaffluent schools (4.8% and 1.5% was significant. Risk factors for overweight and obesity were affluence, higher maternal education, parental history of obesity, frequent fast food intake, and television (TV viewing more than 2 h/day. Conclusion: Overweight and obesity among school-going adolescents is a crisis facing even smaller cities in India. Behavior change communication should be focused to adolescents, especially of the affluent section, toward restricting fast food intake, and TV viewing.

    Full Text Available La actividad industrial, el transporte de combustibles y las fugas de tanques y cañerías provocan frecuentemente derrames de hidrocarburos durante la manipulación y el uso de los mismos, que contaminan el suelo con el riesgo de alcanzar las capas freáticas. Dentro de los métodos de remediación de suelos contaminados, la fitorremediación es una de las técnicas de remoción de contaminantes para recuperar la salud del suelo que combina la acción de las plantas con los microorganismos asociados a ellas. En el presente trabajo se utilizó el proceso de remediación menos costoso, no se emplearon fertilizantes, ni se incorporaron bacterias seleccionadas por su capacidad remediadora, sino que se aprovechó la propia actividad de los microorganismos (atenuación natural. Ciertas propiedades biológicas del suelo pueden emplearse para monitorear la marcha de un proceso fitorremediador. En el experimento se emplearon dos concentraciones de diésel-oil en suelo (1 y 2%, con la presencia de plantas de Spartina argentinensis y Melilotus alba, se evaluaron la respiración, la biomasa microbiana y el cociente respiratorio en dos momentos. Hacia el final del experimento, la producción de CO2 se vio incrementada por la presencia de diésel-oil. La biomasa microbiana aumentó con la menor concentración de diésel-oil pero la mayor concentración provocó probablemente un efecto tóxico sobre los microorganismos, en consecuencia, el mayor estrés causado por la concentración de contaminante (2% de diésel-oil quedó demostrado con el qCO2. La importancia de los parámetros evaluados radica en que permiten conocer la respuesta de las comunidades microbianas del suelo ante la presencia del diésel-oil.

    Full Text Available Esse trabalho tem como objetivo avaliar o incremento em diâmetro da espécie Swietenia machophylla em um sistema Agroflorestal. Em uma área de 1 ha foram alocadas 5 parcelas de 12 x 24 m. As medições foram realizadas em  três ocasiões, sendo: Janeiro de 2014, Janeiro de 2015 e Julho de 2015. Para construção dos histogramas de frequência foram testados os métodos de Sturges e “empírico”. Em um segundo plano histogramas de crescimento foram elaborados tendo em vista a visualização dos diâmetros de cada indivíduo para análise do incremento em diâmetro. O melhor resultado para construção dos histogramas foi o método “empírico”, pois apresentou menor erro. O incremento no DAP médio foi de 0,58 cm entre as três medições, no primeiro período o incremento em diâmetro foi de 11,32, no segundo 11,76 cm e no último 11,90 cm.

    Full Text Available Foram estudadas as correlações lineares simples, múltiplas e não-lineares entre os parâmetros erosividade da chuva, da enxurrada e da chuva-enxurrada e as perdas de solo provocadas por chuvas erosivas num Luvissolo. Os dados correspondentes ao período de 1986-1990 foram obtidos na estação experimental de Sumé (PB, pertencente à Universidade Federal da Paraíba - UFPB. Para determinar os parâmetros erosividade da chuva, da enxurrada e da chuva-enxurrada, foram analisadas chuvas individuais registradas em 136 pluviogramas. O volume de enxurrada isolado ou em combinação com características da chuva contribuiu, de forma significativa, para melhorar a estimativa das perdas de solo de chuvas individuais. Os parâmetros erosividade da chuva-enxurrada a(Vu α I30b; a(Vu α I5b; a(EIAb e da enxurrada a(Vub foram os melhores estimadores das perdas de solo para chuvas individuais. Dentre os parâmetros da erosividade da chuva, os que melhor se correlacionaram com as perdas de solo foram aqueles que incluíram o produto do volume da chuva pela intensidade máxima em trinta minutos a(VrI30.

    Full Text Available Este trabalho apresenta uma retrospectiva do conceito de parâmetro na teoria de Princípios e Parâmetros e mostra que: a no primeiro estágio da teoria, os parâmetros eram concebidos como propriedades associadas a Princípios e b no segundo estágio, como propriedades do léxico, mais especificamente do léxico funcional.. Essa segunda visão também sofreu uma evolução, de um conceito substantivo, para um conceito formal de classes funcionais. O trabalho discute ainda a noção de parâmetros associados a diferentes níveis de representação.This paper presents an overview of the concept of parameter in the Principles and Parameters theory, showing that a in the first stage parameters were conceived as variation associated to the Principles and b in the second stage as properties of the lexicon, and more specifically as properties of functional categories. The latter view has also developed from a substantive conception of functional categories to a more formal abstract characterization of functional heads. The paper also discusses parameters related to different levels of representation.

    Full Text Available En este artículo se aborda la calibración de los parámetros del modelo de Heston, utilizando datos correspondientes al índice IBEX 35. Uno de los parámetros más importantes del modelo, es el relativo a la volatilidad de la varianza instantánea. Los resultados muestran que la estimación correspondiente a dicho parámetro, obtenida con datos de volatilidad realizada para el período anterior a la crisis financiera iniciada en agosto de 2007, es considerablemente inferior al obtenido calibrando el modelo a las opciones cotizadas para dicho mes. Por el contrario, el valor estimado con los datos de volatilidad realizada posteriores al inicio de la crisis, es similar al obtenido utilizando volatilidades implícitas. Este hecho muestra el problema para la correcta valoración y gestión del riesgo derivado de las opciones, que conlleva la estimación de los parámetros exclusivamente en base a datos históricos, sin considerar las expectativas que incorporan las volatilidades implícitas de mercado
