    Full Text Available We report an outbreak of contagious ecthyma (CE in a herd of goats at Paso Canoas quarantine station, Panama. The goats were adult intact females. Visible clinical signs became apparent from day 13 after the start of quarantine. We performed clinical examination. Serum biopsy and scabs were collected from crusted lesions in the epithelium of the lips, nose and eyelid corners. Samples were studied by histopathology,complement fixation test, transmission electron microscopy (TEM, DAS-ELISA, viral isolationand nucleic acid amplification tests. Histopathology revealed ortho and parakeratotic hyperkeratosis, epithelial hyperplasia, viral inclusion bodies, keratinocytes with balonoid degeneration, vesicles with neutrophils and degenerated cells, in superficial dermis there is marked neovascularization. Complement fixation test, DAS-ELISA and nucleic acid amplification tests resulted positive for contagious ecthyma. TEM showed viral particles, consistent with Parapoxvirus. Clinical and laboratory findings were consistent with poxvirus infection in the quarantine goat herd.

    Baltimore City was faced with two potential measles outbreaks in 2015. Both cases occurred in the wake of national media attention paid to the Disneyland outbreaks of the same year. A comparative case study approach was used applying qualitative data to elicit best practices in infectious disease protocols in the age of social media. The research also used search engine data from Google Trends to track constituent engagement over time. Across the two case studies, the Baltimore City Health Department identified a number of best practices to inform the public via social media and minimize levels of misinformation and panic. These practices included clarity in messaging across platforms and public health jurisdictions; pre-emptor alerts of potential measles cases to control and shape the media messaging; and targeted, in-person outreach to engage groups in a culturally competent manner. The Baltimore City Health Department's response drew out a critical need for re-examining infectious disease protocols in the age of social media (e.g. contact notification, quarantine, media sensitivity) and anti-vaccination movements that pose new obstacles to government intervention. The benefits and challenges of greater connectivity between providers, patients, and public health officers are discussed. © The Author 2016.

  6. Ionizing radiation quarantine treatments

    OpenAIRE

    Hallman, Guy J.

    1998-01-01

    Irradiation is a viable quarantine disinfestation treatment which has been studied for 40 years although it has received very little commercial use. Two principal obstacles to commercial application, 1) the fact that insects are not killed immediately, and 2) consumer opposition to irradiation, have been allayed to some extent, but the remaining impediment to large-scale commercial use is development of approved protocols by government regulatory agencies in importing countries. The United St...

    1991-01-01

    The use of irradiation as an alternative treatment for commodities subject to infestation by pests of quarantine importance is outlined in this article. A dose of 300 Gy or less has been found to prevent adult emergence when insect eggs or larvae are irradiated and research has shown that such doses will not affect the quality of most commodities. The use of gamma rays from cobalt-60 or caesium-137 sources, as well as electrons or X-rays from linear accelerators, has been approved for food irradiation. Irradiation facilities must meet regulations promulgated by nuclear, health and agricultural quarantine agencies with regard to location, facility design, sources, operation, personnel, dosimetry and other requirements. Education of industry operators and the general public is needed in order to gain acceptance of irradiation as a quarantine treatment. (author). 21 refs, 1 tab

    1996-12-31

    The Baltimore Air Toxics Study is one of the three urban air toxics initiatives funded by EPA to support the development of the national air toxics strategy. As part of this project, the Air Quality Integrated Management System (AIMS) is under development. AIMS is designed to bring together the key components of urban air quality management into an integrated system, including emissions assessment, air quality modeling, and air quality monitoring. Urban area source emissions are computed for a wide range of pollutants and source categories, and are joined with existing point source emissions data. Measured air quality data are used to evaluate the adequacy of the emissions data and model treatments as a function of season, meteorological parameters, and daytime/nighttime conditions. Based on tested model performance, AIMS provides the potential to improve the ability to predict air quality benefits of alternative control options for criteria and toxic air pollutants. This paper describes the methods used to develop AIMS, and provides examples from its application in the Baltimore metropolitan area. The use of AIMS in the future to enhance environmental management of major industrial facilities also will be addressed in the paper.

  11. An overview of quarantine for fruit flies

    International Nuclear Information System (INIS)

    Frampton, E.R.

    2000-01-01

    What is meant by 'quarantine for fruit flies'? The Collins dictionary describes 'quarantine' as a period of isolation or detention, especially of persons or animals arriving from abroad, to prevent the spread of disease. In providing an overview of quarantine for fruit flies, a broader definition needs to be applied, that is, the combination of activities required to maintain the fruit fly status of a particular geographical area - perhaps better referred to as a 'quarantine system'. Familiarity with New Zealand's quarantine system for fruit flies (Diptera: Tephritidae) provides a useful basis for subsequent comparison with other countries' systems where some fruit fly species may be present. But, why have 'quarantine for fruit flies'? The multivoltine life history of many species. combined with a relatively long-lived adult stage and highly fecund females, results in a high potential for rapid population increase (Bateman 1979, Fletcher 1987). These factors and the close association of fruit flies with harvested fruit or vegetables explain the high quarantine profile of these insects. However, there is no international requirement for a country to have a quarantine system and unless there are natural quarantine barriers (e.g., mountain range, oceans, deserts) that can be utilised, effective quarantine by an individual country may be an impossible task. The implementation of a successful quarantine system is very expensive and therefore, it would be expected that any benefits attained outweigh the costs (Ivess 1998). Ivess (1998) listed the following benefits from the implementation of an effective quarantine system: minimising production costs (including post harvest treatments), maintaining competitive advantages for market access due to the ongoing freedom from particular pests of quarantine significance, an environment free from many pests harmful to plant health, the maintenance of ecosystems

  18. Food irradiation as a quarantine treatment

    International Nuclear Information System (INIS)

    Ignatowicz, S.

    1998-01-01

    Because of multiplicity of invertebrate pests of fresh and durable agricultural products which are treaded internationally there are frequent instances were products are unacceptable without an approved prior disinfestation treatment. The majority of these pests are regulated by quarantine inspections at the ports of exit and entry. Where there is risk of rejection of products if quarantine pests are found at inspection it is frequently prudent to apply a disinfestation treatment. Control of these pests in agriculture produce by fumigation is no longer desirable from the points of human health and global environment. Irradiation could be feasible and practical alternative with a broad applicability to commodities and pests. Quarantine disinfestation of most agricultural products seems to be achievable at the recommended generic dose of 300 Gy. Because irradiation applied at doses ranging about 300 Gy does not cause immediate mortality of all insects, mites or nematodes, live pests could be present after treatment of agricultural produce intended for international trade. In such case a marker of irradiation that is easily applied may be very useful in allaying concerns of some quarantine inspectors that inevitably occur when a living insect of quarantine importance is found in a shipment.

    We study the critical effect of quarantine on the propagation of epidemics on an adaptive network of social contacts. For this purpose, we analyze the susceptible-infected-recovered (SIR) model in the presence of quarantine, where susceptible individuals protect themselves by disconnecting their links to infected neighbors with probability w, and reconnecting them to other susceptible individuals chosen at random. Starting from a single infected individual, we show by an analytical approach and simulations that there is a phase transition at a critical rewiring (quarantine) threshold wc separating a phase (w =wc) where the disease does not spread out. We find that in our model the topology of the network strongly affects the size of the propagation, and that wc increases with the mean degree and heterogeneity of the network. We also find that wc is reduced if we perform a preferential rewiring, in which the rewiring probability is proportional to the degree of infected nodes.

    Treatment and quarantine are efforts to cure as well as to overcome the spread of diseases including measles. The spread of measles can be expressed by mathematical modelling in the form of nonlinear dynamical systems. In this study was conducted on the spread of measles by considering the effect of treatment and quarantine on the infected individuals. By using the basic reproduction number of the model, can be analyzed the effects of treatment and quarantine to reduce the spread of measles. Basic reproduction number of models is monotonically descreasing as treatment and quarantine increasing. Numerical simulations conducted on the analysis of the results. The results showed that treatment and quarantine was given to infected individuals who were infectious has a major influence to eliminate measles from the system.

  15. Ionizing radiation quarantine treatments against tephritid fruit flies: a review

    Energy Technology Data Exchange (ETDEWEB)

    Hallman, G. J. [USDA-ARS, Weslaco, TX (United States)

    1999-06-15

    Fruit flies of the family Tephritidae are considered the most important insect pest risk carried by exported fruits worldwide. Fruits suspected of harboring fruit fly eggs and larvae must be treated to control virtually 100% of any tephritids present. Irradiation is unique among quarantine treatments in that it is the only treatment used which does not cause acute mortality; instead, insects are prevented from maturing or are sterilized. Tephritids have been the most studied group of quarantined pests as far as irradiation; minimum absorbed doses confirmed with large-scale testing to provide control to the probit 9 level (99.9968%) have ranged from 50 to 250 Gy. Considerable work has been done with the Mediterranean fruit fly, Ceratitis capitata (Wiedemann), one of the most important quarantined pests worldwide, and doses suggested to provide quarantine security have varied widely. The fact that insects are still alive for some time after irradiation has been one of the major obstacles to its use. Irradiation may be the most widely applicable quarantine treatment from the standpoint of fruit quality. However, some important fruits shipped across quarantine barriers (mangoes, Mangifera indica L., and citrus) may suffer from doses as low as 150 Gy when applied on a commercial scale where much of the fruit load may receive 300 Gy. Fortunately, some of the important tephritids attacking these fruits, such as Anastrepha spp., can be controlled with lower doses. Mainland USA has begun to use irradiation as a quarantine treatment for some fruits imported from Hawaii since April 1995 and remains the only country using irradiation as a quarantine treatment, although on a very limited basis. Irradiation offers some additional risk abatement advantages over other quarantine treatments. © 1999 Published by Elsevier Science B.V. All rights reserved. (author)

    We study the critical effect of quarantine on the propagation of epidemics on an adaptive network of social contacts. For this purpose, we analyze the susceptible-infected-recovered model in the presence of quarantine, where susceptible individuals protect themselves by disconnecting their links to infected neighbors with probability w and reconnecting them to other susceptible individuals chosen at random. Starting from a single infected individual, we show by an analytical approach and simulations that there is a phase transition at a critical rewiring (quarantine) threshold w(c) separating a phase (wspread out. We find that in our model the topology of the network strongly affects the size of the propagation and that w(c) increases with the mean degree and heterogeneity of the network. We also find that w(c) is reduced if we perform a preferential rewiring, in which the rewiring probability is proportional to the degree of infected nodes. ©2011 American Physical Society

  8. The use of radiation in quarantine on insects

    International Nuclear Information System (INIS)

    Al-Oraby, M. N. A.

    2012-01-01

    With world trade in agricultural commodities increasing, the introduction of exotic insects into new areas, where they become pests, will increase. The development and application of quarantine treatments or other mitigation approaches to prevent pest introduction in traded commodities raise many research and regulatory issues. The probit 9 standard for quarantine treatment efficacy has given way to risk based alternatives. Development of generic treatments to control broad groups of insects or insects in all commodities can expedite new trade in agricultural products. An innovative technique using radio-frequency (RF) and Microwave (MW) heating treatments was proposed as an alternative quarantine treatment in nuts. The practical future application in industry should be possible after solving their problems of high cost, non-uniform heating and quality damage. (author)

    The City of Baltimore, like any city, is the sum of its component neighborhoods, institutions, businesses, cultures, and, ultimately, its people. It is also an organism in its own right, with distinct geography, history, infrastructure, and environments that shape its residents even as it is shaped by them. Sometimes these interactions are obvious but often they are not; while basic economic patterns are widely documented, the distribution of socio-spatial and environmental connections often hides below the surface, as does the potential that those connections hold. Here we present results of a collaborative initiative on the geography, design, and policy of socio-environmental dynamics of Baltimore. Geospatial data derived from satellite imagery, demographic databases, social media feeds, infrastructure plans, and in situ environmental networks, among other sources, are applied to generate an interactive portrait of Baltimore City's social, health, and well-being dynamics. The layering of data serves as a platform for visualizing the interconnectedness of the City and as a database for modeling risk interactions, vulnerabilities, and strengths within and between communities. This presentation will provide an overview of project findings and highlight linkages to education and policy.

  12. Loop-mediated Isothermal Amplification Assay to Rapidly Detect Wheat Streak Mosaic Virus in Quarantined Plants

    2015-12-01

    Full Text Available We developed a loop-mediated isothermal amplification (LAMP method to rapidly diagnose Wheat streak mosaic virus (WSMV during quarantine inspections of imported wheat, corn, oats, and millet. The LAMP method was developed as a plant quarantine inspection method for the first time, and its simplicity, quickness, specificity and sensitivity were verified compared to current reverse transcription-polymerase chain reaction (RT-PCR and nested PCR quarantine methods. We were able to quickly screen for WSMV at quarantine sites with many test samples; thus, this method is expected to contribute to plant quarantine inspections.

  13. NAA of an iridium tracer to determine soot exposure of students commuting on Baltimore`s buses

    Epidemiologic studies suggest that short-term increases in indices of particulate air pollution are associated with increased mortality and morbidity from respiratory and cardiovascular diseases. An important component of urban aerosol, diesel soot, is a known respiratory irritant and contains mutagenic and carcinogenic organic compounds. In the United States, motor vehicles are thought to be the largest single source of atmospheric soot and account for {approximately}36% of the annual anthropogenic emission of toxic polynuclear aromatic hydrocarbons (PAH). Much of the motor-vehicle-derived PAH originates from diesel-powered vehicles because their PAH emissions are up to 50-fold greater than those from gasoline engines. In Baltimore, city high school students take public buses to school and, often, must stand at bus stops while many diesel buses pass or stop before their own buses arrive. To estimate student exposures to soot emitted from public diesel buses (MTA) during commutes to city high schools, the Baltimore municipal fuel supply was tagged with an iridium tracer, and exposure was monitored during commutes with personal aerosol monitors as a part of the Baltimore Environmental Justice Project.

  9. Quarantine disinfestation of tropical fruits: non-chemical options

    International Nuclear Information System (INIS)

    Heather, N.W.

    1994-01-01

    Residue-free methods of disinfestation of tropical fruits against pests of quarantine significance are reviewed. The most important of these pests in fruits to be exported are fruit flies, and the basic methods which are non-chemical and hence meet a residue-free criterion are physical treatments with heat, cold, and irradiation. Worldwide, there are more than 30 species of fruit flies of the family Tephritidae which are of major importance as quarantine pests. There are however a number of pests other than fruit flies which are also of major quarantine importance. Treatments must have very high levels of efficacy to be fully effective, typically in the range of 99.99 percent to 99.996 percent (Probit 8.7-9). At these levels they must not cause unacceptable damage to fruit. Fruits differ in their tolerance of treatments and there is thus scope to choose and manipulate treatments for the best outcomes in economic terms and product quality. Combinations of methods are possible or even a holistic, systems approach in which the contribution of all influences on pest survival in the growing and handling system are taken into account

  10. Quarantine, exports and animal disease in Australia 1901-2010.

    Science.gov (United States)

    Turner, Aj

    2011-09-01

    The Constitution forming the Australian Commonwealth Government on 1 January 1901 provided that animal and animal products imported into and exported from Australia would be under the authority of the national government. By mutual agreement, the Quarantine Act 1908 provided for the states to continue the delivery of services under contract until 1995 when the Commonwealth took back full responsibility for quarantine services. In the 1940s, 50s and 60s there were world pandemics of livestock diseases and Australia ceased the import of many species. By the 1970s, the livestock industries sought relaxation of import restrictions to gain access to diversified genetic stock. By the use of new technologies, many species can now be imported into Australia through tight importation protocols. With the advent of the World Trade Organization and implementation of the Sanitary Phytosanitary Agreement, Australia has developed a risk-based framework to support the development of import conditions for animals and animal products. Australia's 'Acceptable Level of Protection' has been set to provide a low likelihood of disease entry. Being an island continent, Australia can apply strong controls over imports and exports of all commodities and relatively few outbreaks of exotic animal diseases have occurred by breach of quarantine, but the outbreaks of rinderpest in 1923 and equine influenza in 2007 were notable exceptions. © 2011 The Author.

    Irradiation quarantine was mainly used on food and fruit for sterilization to be qualified for import. Irradiation parameters were formulated based on the bacterial content and other factors. The goods usually have short shelf-life and with the time growing, the bacterial content is increasing. Therefore reducing the residence time of the goods in the factory and further reducing the difficulty of processing are significantly important. Because irradiation industry has special requirement for safety, how to guarantee the safety of the stuff, and irradiation dose precision are also need to pay attention to while optimizing logistics.

    An engineer and a computer expert from Goddard Space Flight Center were assigned to provide technical assistance in the design and installation of a computer assisted system for dispatching and communicating with fire department personnel and equipment in Baltimore City. Primary contributions were in decision making and management processes. The project is analyzed from four perspectives: (1) fire service; (2) technology transfer; (3) public administration; and (5) innovation. The city benefitted substantially from the approach and competence of the NASA personnel. Given the proper conditions, there are distinct advantages in having a nearby Federal laboratory provide assistance to a city on a continuing basis, as is done in the Baltimore Applications Project.

    The Apollo 11 mission, the first manned lunar mission, launched from the Kennedy Space Center, Florida via a Saturn V launch vehicle on July 16, 1969 and safely returned to Earth on July 24, 1969. The Saturn V vehicle was developed by the Marshall Space Flight Center (MSFC) under the direction of Dr. Wernher von Braun. Aboard were Neil A. Armstrong, commander; Michael Collins, Command Module (CM) pilot; and Edwin E. Aldrin Jr., Lunar Module (LM) pilot. The CM, piloted by Michael Collins remained in a parking orbit around the Moon while the LM, named 'Eagle'', carrying astronauts Neil Armstrong and Edwin Aldrin, landed on the Moon. Armstrong was the first human to ever stand on the lunar surface, followed by Edwin (Buzz) Aldrin. During 2½ hours of surface exploration, the crew collected 47 pounds of lunar surface material for analysis back on Earth. The recovery operation took place in the Pacific Ocean where Navy para-rescue men recovered the capsule housing the 3-man Apollo 11 crew. The crew was taken to safety aboard the USS Hornet, where they were quartered in a mobile quarantine facility. Shown here is the Apollo 11 crew inside the quarantine facility as prayer is offered by Lt. Commander John Pirrto, USS Hornet Chaplain accompanied by U.S. President Richard Nixon (front right). With the success of Apollo 11, the national objective to land men on the Moon and return them safely to Earth had been accomplished.

    Gittelsohn, Joel; Zonderman, Alan B.; Evans, Michele K.; Gary-Webb, Tiffany L.

    2011-01-01

    Objectives. To investigate the association between walkability and obesity, we studied adults residing in Baltimore City, Maryland, in neighborhoods of varying racial and socioeconomic composition. Methods. We conducted a cross-sectional study of 3493 participants from the study Healthy Aging in Neighborhoods of Diversity across the Life Span. We used the Pedestrian Environment Data Scan to measure neighborhood walkability in 34 neighborhoods of diverse racial and socioeconomic composition in which the study participants lived. Confirmatory factor analysis was used to determine walkability scores. Multilevel modeling was used to determine prevalence ratios for the association between walkability and obesity. Results. Among individuals living in predominately White and high-socioeconomic status (SES) neighborhoods, residing in highly walkable neighborhoods was associated with a lower prevalence of obesity when compared with individuals living in poorly walkable neighborhoods, after adjusting for individual-level demographic variables (prevalence ratio–[PR] = 0.58; P = walkability and obesity for individuals living in low-SES neighborhoods was not significant after accounting for main mode of transportation (PR = 0.85; P = .060). Conclusions. Future research is needed to determine how differences in associations by neighborhood characteristics may contribute to racial disparities in obesity. PMID:21164099

    2010-01-01

    The Baltimore Longitudinal Study of Aging (BLSA) was established in 1958 and is one the oldest prospective studies of aging in the USA and the world. The BLSA is supported by the National Institute of Aging (NIA) and its mission is to learn what happens to people as they get old and how to sort out changes due to aging and from those due to disease or other causes. In 1986, an autopsy program combined with comprehensive neurologic and cognitive evaluations was established in collaboration with the Johns Hopkins University Alzheimer’s Disease Research Center (ADRC). Since then, 211 subjects have undergone autopsy. Here we review the key clinical neuropathological correlations from this autopsy series. The focus is on the morphological and biochemical changes that occur in normal aging, and the early neuropathological changes of neurodegenerative diseases, especially Alzheimer’s disease (AD). We highlight the combined clinical, pathologic, morphometric, and biochemical evidence of asymptomatic AD, a state characterized by normal clinical evaluations in subjects with abundant AD pathology. We conclude that in some individuals, successful cognitive aging results from compensatory mechanisms that occur at the neuronal level (i.e., neuronal hypertrophy and synaptic plasticity) whereas a failure of compensation may culminate in disease.

    Our objective was to identify major dietary sources of whole grains and to describe the construction of a database of whole grain content of foods. Dietary information was collected with 7-d food records from men and women in the Baltimore Longitudinal Study of Aging, mean age 62.1 +/- 16.0 years, who participated in the dietary assessment portion of the study (n = 1516), and estimates of whole grain intake were obtained from a newly developed database. The Pyramid Servings database and 1994-1996 Continuing Survey of Food Intakes by Individuals (CSFII) recipe ingredients database were then used to calculate both servings and gram weights of whole grain intakes. Mean intakes of whole grains, refined grains, and total grains, as well as frequency of intake for major whole grain food groups and whole grain content for each group, were calculated. Top contributors of whole grains were ready-to-eat breakfast cereals (made with whole grain as well as bran), hot breakfast cereals (made with whole grain), multi-grain bread, and whole wheat bread. While more research is needed to better understand the benefits of whole grains, the development of research tools, including databases to accurately assess whole grain intake, is a critical step in completing such research.

  14. The philosophy of quarantine treatment as related to low-dose radiation

    1985-01-01

    The purpose for quarantine treatment is to prevent establishment of exotic pest populations from quarantined areas to nonquarantined areas through movement of host commodities. Quarantine treatment schedules approved by the Animal Plant Health Inspection Service (APHIS), U.S. Dept. of Agriculture (USDA), appear in its ''Plant Protection and Quarantine Programs Treatment Manual.'' These treatment schedules were developed through research demonstrating that when followed to the letter, quarantine security or negligible pest risk would be achieved. Negligible pest risk is currently synonymous with probit 9, the level of security at which no more than 3.2 pests per 100,000 treated will survive. Probits are based on mortality; therefore, relatively high dosages will be required and in some instances could damage the commodity at the dosage necessary to kill the pest. If the purpose of quarantine treatment is to prevent perpetuation of the pest species into nonquarantined areas, the criterion should be based on the ability of the treated pests to reproduce. The criteria currently being discussed by APHIS and the Agricultural Research Service are presented. Two key criteria are a redefinition of negligible pest risk and the concept of a two-stage quarantine treatment schedule

  16. The borderline of 'empire': Japanese maritime quarantine in Busan c.1876-1910.

    Science.gov (United States)

    Kim, Jeong-Ran

    2013-04-01

    This paper seeks to balance the regional and thematic focus of cholera historiography by examining maritime quarantine in Busan, as it was devised and implemented by Japanese officials and doctors during the pre-colonial period. It also places the relationship between Korea and Japan in the context of relations with China, Russia and Britain. This paper shows that quarantine measures in Busan and other Korean ports reflected the rise of Japanese imperial power and the increasing desire on the part of the Japanese to establish an effective borderline for their regional empire. From 1879 Japan began to impose maritime quarantine in Busan, where Japanese influence was very strong even before the colonial period, though at that time Japan was unable to perform quarantine in its own ports independently due to the objections of Western powers, particularly Britain. Victories in the Sino-Japanese and Russo-Japanese wars established Japan as a regional power on equal terms with the West, and as the dominant power in Korea and Eastern Asia. With the acquisition of the right to impose quarantine in its homeland, Japan strengthened and extended the range of quarantine from Japan to Korea, China and Russia. Now quarantine screened Japan from potentially harmful agents – pathogenic and political – and its functions diversified further as modernisation and imperial expansion gathered pace. The reliance which Japan placed upon quarantine in maintaining its empire explains why it was increasingly out of step with other powers regarding international sanitary precautions. The Japanese maritime quarantine in Busan during this period therefore shows many aspects of Japan’s ‘national empire’.

    Quarantine treatment enables export of avocado fruit (Persea americana) to parts of the world that enforce quarantine against fruit fly. The recommended cold-based quarantine treatment (storage at 1.1°C for 14 days) was studied with two commercial avocado cultivars 'Hass' and 'Ettinger' for 2 years. Chilling injuries (CIs) are prevalent in the avocado fruit after cold-quarantine treatment. Hence, we examined the effect of integrating several treatments: modified atmosphere (MA; fruit covered with perforated polyethylene bags), methyl jasmonate (MJ; fruit dipped in 2.5 μM MJ for Hass or 10 μM MJ for Ettinger for 30 s), 1-methylcyclopropene (1-MCP; fruit treated with 300 ppb 1-MCP for 18 h) and low-temperature conditioning (LTC; a gradual decrease in temperature over 3 days) on CI reduction during cold quarantine. Avocado fruit stored at 1°C suffered from severe CI, lipid peroxidation, and increased expression of chilling-responsive genes of fruit peel. The combined therapeutic treatments alleviated CI in cold-quarantined fruit to the level in fruit stored at commercial temperature (5°C). A successful therapeutic treatment was developed to protect 'Hass' and 'Ettinger' avocado fruit during cold quarantine against fruit fly, while maintaining fruit quality. Subsequently, treated fruit stored at 1°C had a longer shelf life and less decay than the fruit stored at 5°C. This therapeutic treatment could potentially enable the export of avocado fruit to all quarantine-enforcing countries. Similar methods might be applicable to other types of fruit that require cold quarantine.

    The research vessel Chikyu is expanding new frontiers in science, technology, and international collaboration through deep-sea expedition. The Chikyu (length: 210 m, gross tonnage: 56752 tons) has advanced and comprehensive scientific research facilities. One of the scientific purposes of the vessel is to investigate into unexplored biosphere (i.e., undescribed extremophiles) on the Earth. Therefore, "the onboard laboratory" provides us systematic microbiological protocols with a physical containment situation. In parallel, the onboard equipments provide sufficient space for fifty scientists and technical support staff. The helicopter deck also supports various logistics through transporting by a large scale helicopter (See, http://www.jamstec.go.jp/chikyu/eng/). Since the establishment of Panel on Planetary Protection (PPP) in Committee on Space Research (COSPAR), we have an international consensus about the development and promulgation of planetary protection knowledge, policy, and plans to prevent the harmful effects of biological contamination on the Earth (e.g., Rummel, 2002). However, the matter to select a candidate location of initial quarantine at BSL4 level is often problematic. To answer the key issue, we suggest that international waters can be a meaningful option with several advantages to conduct initial onboard-biological quarantine investigation. Hence, the research vessel Chikyu is promising for further PPP requirements (e.g., Enceladus sample return project: Tsou et al., 2012).

  20. Early to middle Jurassic salt in Baltimore Canyon trough

    A pervasive, moderately deep (5-6 s two-way traveltime), high-amplitude reflection is traced on multichannel seismic sections over an approximately 7500 km² area of Baltimore Canyon Trough. The layer associated with the reflection is about 25 km wide, about 60 m thick in the center, and thins monotonically laterally, though asymmetrically, at the edges. Geophysical characteristics are compatible with an interpretation of this negative-polarity reflector as a salt lens deposited on the top of a synrift evaporite sequence. However, alternative interpretations of the layer as gas-saturated sediments, an overpressured shale, or a weathered igneous intrusion are also worthy of consideration.Geophysical analyses were made on three wavelet- and true-amplitude processed multichannel seismic dip lines. The lens-shaped layer demarked by the reflection has a velocity of 4.4 km/s; the lens lies within strata having velocities of 5.3 to 5.7 km/s. A trough marking the onset of the lens has an amplitude that is 10 to 20 db greater than reflections from the encasing layers and an apparent reflection coefficient of -0.24. Using amplitude versus offset analysis methods, we determined that observed reflection coefficients, though variable, decrease consistently with respect to increasing offset. Linear inversion yields a low density, about 2.2 g/cc. Integration of one of the true-amplitude-processed lines and one-dimensional modeling of the layer provide data on the impedance contrast and interference patterns that further reinforce the salt lens interpretation.The thin, horizontal salt lens was probably deposited or precipitated during the Jurassic in a shallow, narrow (peripheral) rift basin, as rifting progressed down the North Atlantic margin. Unlike thicker deposits in other areas that deformed and flowed, often into diapir structures, this thin lens has remained relatively undisturbed since deposition.

    There is limited longitudinal research examining incarceration and subsequent changes in drug use among people who inject drugs (PWID) in the United States. The objective of the current study was to characterize the frequency of incarceration and estimate the association between incarceration and subsequent injection drug use among current and former PWIDs in one US city. ALIVE (AIDS Linked to the Intravenous Experience) is a prospective cohort study of current and former PWIDs, with semi-annual follow-up occurring since 1988. Baltimore, Maryland, USA. A total of 3245 participants with 48 738 study visits were included. Participants enrolled from 1988 to 2012 with a median of 13 follow-up visits per participant (Interquartile range = 7-25). Incarcerations were defined as any self-reported jail or prison stays in the previous 6 months that were ≥7 days or longer. The primary outcome was defined as any self-reported injection drug use in the previous 6 months. At baseline, 29% were female, 90% African American and 33% HIV-positive. Fifty-seven per cent of participants experienced at least one incarceration episode. After adjusting for confounders, there was a positive association between incarceration and subsequent injection drug use [adjusted odds ratio (AOR) = 1.48, 95% confidence interval (CI) = 1.37-1.59]; however, stratified analysis showed that the effect was restricted to those who were not injecting at the time of incarceration (AOR = 2.11, 95% CI = 1.88-2.37). In the United States, incarceration of people who had previously stopped injecting drugs appears to be associated with an increased risk of subsequent injecting. © 2015 Society for the Study of Addiction.

    With the development of modern information technology, the traditional teaching mode becomes more deficient for the requirement of modern education. Plant Quarantine has been accepted as the common course for the universities of agriculture in China after the entry of WTO. But the teaching resources of this course are not enough especially for most universities with lack base. The characteristic of e-learning is regarded as one way to solve the problem of short teaching resource. PQRTS (Plant Quarantine Remote Teaching System) was designed and developed with JSP (Java Sever Pages), MySQL and Tomcat in this study. The system included many kinds of plant quarantine teaching resources, such as international glossary, regulations and standards, multimedia information of quarantine process and pests, ppt files of teaching, and training exercise. The system prototype implemented the functions of remote learning, querying, management, examination and remote discussion. It could be a tool for teaching, teaching assistance and learning online.

  4. Summary report on the use of irradiation as a quarantine treatment of agricultural commodities

    International Nuclear Information System (INIS)

    1985-01-01

    Considerable data are available to demonstrate that gamma irradiation is an effective quarantine treatment for papaya infested with fruit fly species found in Hawaii. These data are acceptable to the USDA-APHIS as a quarantine treatment for this commodity. However, its practical application can be realized only when FDA approves the use of irradiation, either for this purpose alone or as a process of food preservation. Additional data are needed to develop quarantine treatment schedules for irradiation of other commodities such as citrus, stone fruits, tropical fruits, etc., against these and other insect species. For this reason, a Consultant Meeting was convened at the East-West Center, University of Hawaii, Honolulu, Hawaii from 21 to 23 November, 1983, to evaluate existing data and to define future activities to establish the possible use of irradiation as an acceptable quarantine treatment

    1999-01-01

    Baltimore City and its metropolitan area are supplied with water from three reservoirs, Liberty Reservoir, Prettyboy Reservoir, and Loch Raven Reservoir. Prettyboy and Loch Raven Reservoirs are located on the Gunpowder Falls (figure 1). The many uses of the reservoir system necessitate coordination and communication among resource managers. The 1996 Amendment to the Safe Drinking Water Act require States to complete source-water assessments for public drinking-water supplies. As part of an ongoing effort to provide safe drinking water and as a direct result of these laws, the City of Baltimore and the Maryland Department of the Environment (MDE), in cooperation with other State and local agencies, are studying the Gunpowder Falls Basin and its role as a source of water supply to the Baltimore area. As a part of this study, the U.S. Geological Survey (USGS), in cooperation with the Maryland Geological Survey (MGS), with funding provided by the City of Baltimore and MDE, is examining sediment accumulation in Loch Raven Reservoir. The Baltimore City Department of Public Works periodically determines the amount of water that can be stored in its reservoirs. To make this determination, field crews measure the water depth along predetermined transects or ranges. These transects provide consistent locations where water depth, or bathymetric, measurements can be made. Range surveys are repeated to provide a record of the change in storage capacity due to sediment accumulation over time. Previous bathymetric surveys of Loch Raven Reservoir were performed in 1943, 1961, 1972, and 1985. Errors in data-collection and analysis methods have been assessed and documented (Baltimore City Department of Public Works, 1989). Few comparisons can be made among survey results because of changing data-collection techniques and analysis methods.

    Quarantine strategies are frequently used to control or reduce the transmission risks of epidemic diseases such as SARS, tuberculosis and cholera. In this paper, we formulate a susceptible-exposed-infected-quarantined-recovered model on a scale-free network incorporating the births and deaths of individuals. Considering that the infectivity is related to the degrees of infectious nodes, we introduce quarantined rate as a function of degree into the model, and quantify the basic reproduction number, which is shown to be dependent on some parameters, such as quarantined rate, infectivity and network structures. A theoretical result further indicates the heterogeneity of networks and higher infectivity will raise the disease transmission risk while quarantine measure will contribute to the prevention of epidemic spreading. Meanwhile, the contact assumption between susceptibles and infectives may impact the disease transmission. Furthermore, we prove that the basic reproduction number serves as a threshold value for the global stability of the disease-free and endemic equilibria and the uniform persistence of the disease on the network by constructing appropriate Lyapunov functions. Finally, some numerical simulations are illustrated to perform and complement our analytical results.

    In Indonesia there are many breeders of cattle that are actually used as a livelihood so that Indonesia is prone to the spread of anthrax disease. This disease can be transmitted through indirect contacts such as deep impurities, saliva and the like. Anthrax disease is a type of disease caused by bacteria and there is a link between livestock and humans as the host. Anthrax disease with quarantine special factors can be modelled with SEIQR where existed from susceptible, exposed, symptomatic infected, quarantine and recovered compartment with research method used that is quantitative method, so different with disease models caused by bacteria in general.In this study we will determine the qualitative analysis of the anthrax disease distribution model with goal of research are to obtain model transmission Anthrax, to find equilibrium point of model and to find the basic reproduction number R 0, where R0 aims to determine the spread of disease or the absence of disease spread through endemic equilibrium stability analysis. The goal from this research is compare stability analysis between model with quarantine and model without quarantine use Routh-Hurwitz criteria to prove that E 1 and E 2 are asymptotic stability equilibrium so from this research conclude that quarantine population can speed up recovered population to be free disease condition from Anthrax.

    2016-03-01

    Quarantine is designed primarily to prevent the introduction of transmissible diseases to zoological collections. Improvements in preventive medicine, disease eradication, and comprehensive pathology programs call into question current industry quarantine standards. Disease risk analysis was used at the San Diego Zoo (SDZ) and the SDZ Safari Park to eliminate quarantine isolation and transmissible disease testing for animals transferred between the two institutions. To determine if a risk-based approach might be valid between other institutions and SDZ, we reviewed quarantine data for animals arriving at SDZ from 81 Association of Zoos and Aquariums (AZA)-accredited and 124 other sources (e.g., non-AZA-accredited institutions, private breeders, private dealers, governmental bodies) over a 5-yr period (2009-2013). No mammal or herptile failed quarantine due to transmissible diseases of concern. Approximately 2.5% of incoming birds failed quarantine due to transmissible disease; however, all 14 failed individuals were obtained from three nonaccredited sources (private breeders, confiscation). The results of our study suggest that a risk-based approach could be used to minimize or eliminate quarantine for the transfer of animals from institutions with comprehensive disease surveillance programs and/or preshipment testing practices. Quarantine isolation with testing remains an essential defense against introducing transmissible diseases of concern when there is a lack of health knowledge about the animals being received.

    Full Text Available Phytophthora ramorum is a quarantine pathogen that causes leaf blight and shoot dieback of the crown, bark cankers and death on a number of both ornamental and forest trees, especially in North America and northern Europe, where it has produced severe outbreaks.In Italy it was first reported in 2002, on Rhodondendron yakushimanum in a Piedmont nursery; after that it seemed to have disappeared, only to re-emerge in 2013 when numerous isolates were detected on batches of Viburnum tinus plants growing in some nurseries in the Pistoia area (Tuscany, which is an important district in the trade of nursery plants world-wide. This work reports on a number of laboratory tests that were carried out on isolates from infected plant samples. The micromorphological and macromorphological characteristics of the pathogen growing on carrot agar (CA, corn meal agar (CMA, malt extract agar (MEA potato dextrose agar, and V8 agar with added PARPNH (see text were determined, as was the growth rate at 10º, 15º, 20º, 25°, 30º, 32º and 35ºC. Molecular analysis was employed to identify the isolates more precisely. Inoculation trials under the bark were also carried out to ascertain the isolate virulence and the Koch’s Postulates.The Plant Protection Service of the Tuscan Region (SFR, Servizio Fitosanitario Regionale was alerted as soon as the pathogen infection was detected and it took the prescribed steps to eradicate the infection in the field and prevent the recurrence of an epidemic.

  16. Accepted monitoring or endured quarantine? Ebola contacts' perceptions in Senegal.

    2017-04-01

    During the 2014-2016 West Africa Ebola epidemic, transmission chains were controlled through contact tracing, i.e., identification and follow-up of people exposed to Ebola cases. WHO recommendations for daily check-ups of physical symptoms with social distancing for 21 days were unevenly applied and sometimes interpreted as quarantine. Criticisms arose regarding the use of coercion and questioned contact tracing on ethical grounds. This article aims to analyze contact cases' perceptions and acceptance of contact monitoring at the field level. In Senegal, an imported case of Ebola virus disease in September 2014 resulted in placing 74 contact cases in home containment with daily visits by volunteers. An ethnographic study based on in-depth interviews with all stakeholders performed in September-October 2014 showed four main perceptions of monitoring: a biosecurity preventive measure, suspension of professional activity, stigma attached to Ebola, and a social obligation. Contacts demonstrated diverse attitudes. Initially, most contacts agreed to comply because they feared being infected. They adhered to the national Ebola response measures and appreciated the empathy shown by volunteers. Later, acceptance was improved by the provision of moral, economic, and social support, and by the final lack of any new contamination. But it was limited by the socio-economic impact on fulfilling basic needs, the fear of being infected, how contacts' family members interpreted monitoring, conflation of contacts as Ebola cases, and challenging the rationale for containment. Acceptance was also related to individual aspects, such as the professional status of women and health workers who had been exposed, and contextual aspects, such as the media's role in the social production of stigma. Ethnographic results show that, even when contacts adhere rather than comply to containment through coercion, contact monitoring raises several ethical issues. These insights should contribute to

    The object is to provide a method of operating a dual purpose power station so that the steam supply system is operated at a high load factor. The available steam not required for electricity generation is used to provide process heat and the new feature is that the process plant capacity is determined to make the most economic use of the steam supply system, and not to match the passout capacity of the turbine of the turbogenerator. The product of the process plant should, therefore, be capable of being stored. A dual-purpose power station with a nuclear-powered steam source, turbogenerating means connected to the steam source and steam-powered process plant susceptible to wide variation in its rate of operation is described.

    2012-01-01

    Full Text Available SEIQR (Susceptible, Exposed, Infectious, Quarantined, and Recovered models for the transmission of malicious objects with simple mass action incidence and standard incidence rate in computer network are formulated. Threshold, equilibrium, and their stability are discussed for the simple mass action incidence and standard incidence rate. Global stability and asymptotic stability of endemic equilibrium for simple mass action incidence have been shown. With the help of Poincare Bendixson Property, asymptotic stability of endemic equilibrium for standard incidence rate has been shown. Numerical methods have been used to solve and simulate the system of differential equations. The effect of quarantine on recovered nodes is analyzed. We have also analyzed the behavior of the susceptible, exposed, infected, quarantine, and recovered nodes in the computer network.

  1. The Quarantine Protection of Sub-Antarctic Australia: Two Islands, Two Regimes

    2007-11-01

    Full Text Available Sub-Antarctic Heard Island and Macquarie Island are among Australia’s offshore properties susceptible to colonization by species introduced by humans. While both islands share World Heritage status and are IUCN Category Ia Protected Areas (Strict Nature Reserves, different quarantine protection regimes are in operation. Macquarie Island’s biosecurity appears to be less catered for while the means and likelihood of introductions are greater. The administrative, political, practical and geographical contexts within which quarantine management planning takes place variously impact on the level of quarantine protection provided to both islands. These and other remote sites of high conservation value are unlikely to receive heightened protection until the issues associated with such management contexts receive greater attention.

  2. Mother Nature versus human nature: public compliance with evacuation and quarantine.

    2011-04-01

    Effectively controlling the spread of contagious illnesses has become a critical focus of disaster planning. It is likely that quarantine will be a key part of the overall public health strategy utilised during a pandemic, an act of bioterrorism or other emergencies involving contagious agents. While the United States lacks recent experience of large-scale quarantines, it has considerable accumulated experience of large-scale evacuations. Risk perception, life circumstance, work-related issues, and the opinions of influential family, friends and credible public spokespersons all play a role in determining compliance with an evacuation order. Although the comparison is not reported elsewhere to our knowledge, this review of the principal factors affecting compliance with evacuations demonstrates many similarities with those likely to occur during a quarantine. Accurate identification and understanding of barriers to compliance allows for improved planning to protect the public more effectively. © 2011 The Author(s).

    Tognotti, Eugenia

    2013-02-01

    In the new millennium, the centuries-old strategy of quarantine is becoming a powerful component of the public health response to emerging and reemerging infectious diseases. During the 2003 pandemic of severe acute respiratory syndrome, the use of quarantine, border controls, contact tracing, and surveillance proved effective in containing the global threat in just over 3 months. For centuries, these practices have been the cornerstone of organized responses to infectious disease outbreaks. However, the use of quarantine and other measures for controlling epidemic diseases has always been controversial because such strategies raise political, ethical, and socioeconomic issues and require a careful balance between public interest and individual rights. In a globalized world that is becoming ever more vulnerable to communicable diseases, a historical perspective can help clarify the use and implications of a still-valid public health strategy.

    The present review deals with recent advances showing a notable increase in research and application of nuclear science, with a special, rather renewed focus on use of different types of radiation for their lethal/sterilizing potential against pests of stored products and quarantine as there is an urgent need to reduce the negative impacts of chemical pest control methods on the treated commodities and environment. Various types of radiation have some limitations, but their pragmatic disinfestation potential at postharvest and quarantine level, with possible modifications are discussed. (author)

  5. The geographic epidemiology of Mycobacterium tuberculosis disease in Baltimore, 1971-1995

    Science.gov (United States)

    Obasanjo, Olugbenga Olufemi

    Given the reemergence of Tuberculosis (TB) in the United States (U.S.) in the 1980s and 1990s, several strategies have emerged to combat the disease. A successful tool has been Directly Observed Therapy (DOT). Chaulk, et al. showed that DOT was responsible for the maintaining the decline in TB rates in Baltimore through the corresponding period of an upswing in rates nationally. In this study, we measure the impact of DOT on the geographic pattern of TB in Baltimore. We used Geographical Information System (GIS) methods to compare the geographic patterns of TB in Baltimore before and after the introduction of DOT in the city. We identified both predictors of TB, and differences in geographic units in Baltimore over time. We measured the impact of the introduction of DOT and Rifampin on various treatment outcomes for TB at about the same time. Despite the drop in numbers of TB cases, the spatial distribution of cases generally remained unchanged until 1995. This was confirmed by the fact that similar predictors were identified in all of the years that were analyzed. However, higher proportions of TB cases were found among blacks and females in more recent years. Death rates have increased significantly while corresponding relapse rates and the mean length of therapy have declined significantly. Rifampin was associated with a longer length of therapy before DOT, but with a shorter duration of therapy following the introduction of DOT. In all of the years analyzed, losses to follow-up (LTFU) do not differ from those completing therapy and are not spatially clustered relative to those completing therapy. DOT has been effective in reducing the numbers of TB cases in Baltimore city-wide without an emphasis on so-called "high-risk" patients for LTFU. Thus, any declines in TB case rates are not due to a decline in a particular group or geographic sector of the city. Universal DOT is effective and does not cause a geographic clustering of difficult-to-reach patients. This

    The two-volume report presents the results of an econometric forecast of peak load and electric power demand for the Baltimore Gas and Electric Company (BG ampersand E) through the year 2009. Separate energy sales models were estimated for residential sales in Baltimore City, residential sales in the BG ampersand E service area excluding Baltimore City, commercial sales, industrial sales, streetlighting sales, and Company use plus losses. Econometric equations were also estimated for electric space heating and air conditioning saturation in Baltimore City and in the remainder of the BG ampersand E service territory. In addition to the energy sales models and the electric space conditioning saturation models, econometric models of summer and winter peak demand on the BG ampersand E system were estimated

    2004-01-01

    Spatial relationships between clinical data for pediatric asthmatics (hospital and emergency department utilization rates), and socioeconomic and urban characteristics in Baltimore City were analyzed with the aim of identifying factors that contribute to increased asthma rates. Socioeconomic variables and urban characteristics derived from satellite data explained 95% of the spatial variation in hospital rates. The proportion of families headed by a single female was the most important variable accounting for 89% of the spatial variation. Evidence suggests that the high rates of hospital admissions and emergency department (ED) visits may partially be due to the difficulty of single parents with limited resources managing their child's asthma condition properly. This knowledge can be used for education towards mitigating ED and hospital events in Baltimore City.

    Liverman, James L.

    1978-04-01

    An allocation of naphtha feedstock up to 2,186,000 barrels per year to Baltimore Gas and Electric Company (BG and E) to operate its synthetic natural gas (SNG) facility is being considered. The allocation would enable BG and E to produce 10,800,000 mcf of SNG during a 180 day period. Operation of the plant at design capacity is expected to result in annual pollution emissions as follows: 626.4 tons of sulfur oxides, 168.5 tons of nitrogen oxides and 21.6 tons of particulate matter. Incremental emissions due to plant operations relative to existing emissions in Baltimore County are less than 1%. All Federal and State air quality standards should be met. Treated effluent is to be discharged into the Patapasco River where the environmental impacts are not expected to be significant. The SNG facility has been designed to be in compliance with all applicable Federal, State and local effluent standards. Water consumption requirements of 335,000 gallons per day are not expected to significantly tax the area's water resources. Sound generated by the SNG facility will be inaudible or imperceptible. All other operational impacts on land use, population, visual quality, roadways, community facilities and services and ecological systems were judged to be minimal. Environmental impacts resulting from various alternatives ranging from full allocation through denial of an allocation are discussed.

  13. Contaminant levels and toxicity of sediments and water of Baltimore Harbor and Back River, Maryland

    Logan, D.T.; Jacobs, F.; Mehrotra, N.

    1995-01-01

    The Patapsco and Back River Watershed drains the Baltimore metropolitan area, Maryland's most heavily industrialized and urbanized region. Due to the intensive development and industrialization of the Baltimore metropolitan area over the past 250 years, high levels of contaminants have been discharged into Baltimore Harbor on the Patapsco River and into the Back River. Pollutants historically discharged include heavy metals, petroleum hydrocarbons, pesticides, cyanide, sewage, other organic chemicals, and nutrients. Sources have included industrial and municipal discharges, sewerage overflows, urban runoff, and leaks and spills from vessels and on-land facilities. The Maryland Department of the Environment undertook this study of ambient conditions as part of a developing strategy to assess and improve conditions in the Chesapeake Bay and its tributaries. Past studies were compiled, evaluated, and synthesized to identify the areas of degraded conditions and contaminants of possible concern. Sediment contaminant levels were assessed using historical sediment chemistry data, Effects Range Low and Median concentrations (ER-L and ER-M) as toxicological benchmarks, and a sum of toxicity units approach for multiple contaminants. Data on toxicity testing and biological monitoring was compared to sediment and water quality data. Fish tissue data were used to examine bioaccumulated chemicals. A computerized Geographical Information System (GIS) was used to manipulate and display complex geographical data. The final identification of areas and chemicals of potential concern relied on a syntheses of these results as well as information on present and past contaminant loadings

  14. How can a successful multi-family residential recycling programme be initiated within Baltimore City, Maryland?

    Science.gov (United States)

    Schwebel, Michael B

    2012-07-01

    Baltimore City formally began recycling in 1989 with all neighbourhoods having residential collection by 1992. Although the city of 637 000 has recycled for approximately 20 years, almost all residents in multi-family residential (MFR) housing have been and are still barred from participating at their residences. Discussions with City officials and residents have verified this antiquated policy of exclusion within MFR housing. Yet, the policy is still observed by the Department of Public Works even though the updated single-stream Code states that the 'Director of Public Works must collect all. . .recyclable materials. . .from all dwellings, including multiple-family dwellings'. The purpose of this study's is to provide policies, regulations, and recommendations for implementing requisite MFR recycling within Baltimore City. The study's methodology follows a case study approach by examining three cities in the United States that currently mandate MFR recycling: Chicago, Illinois; Boston, Massachusetts; and Arlington, Virginia. Post-analysis suggests that while some cities' MFR programmes perform poorly, each city's strengths aid in creating specific proposals that can produce a successful MFR recycling program in Baltimore City. These tenets of a future MFR recycling program form the basis of a successful MFR recycling program that will allow all city residents to participate via initiatives in the categories of both programme, accessibility, and informing and self-review.

  7. Evaluation of predicted Medfly (Ceratitis capitata quarantine length in the United States utilizing degree-day and agent-based models [version 1; referees: 2 approved

    Directory of Open Access Journals (Sweden)

    Full Text Available Invasions by pest insects pose a significant threat to agriculture worldwide. In the case of Ceratitis capitata incursions on the US mainland, where it is not officially established, repeated detections are followed by quarantines and treatments to eliminate the invading population. However, it is difficult to accurately set quarantine duration because non-detection may not mean the pest is eliminated. Most programs extend quarantine lengths past the last fly detection by calculating the amount of time required for 3 generations to elapse under a thermal unit accumulation development model (“degree day”. A newer approach is to use an Agent-Based Simulation (ABS to explicitly simulate population demographics and elimination. Here, predicted quarantine lengths for 11 sites in the continental United States are evaluated using both approaches. Results indicate a strong seasonality in quarantine length, with longer predictions in the second half of the year compared with the first; this pattern is more extreme in degree day predictions compared with ABS. Geographically, quarantine lengths increased with latitude, though this was less pronounced under the ABS. Variation in quarantine lengths for particular times and places was dramatically larger for degree day than ABS, generally spiking in the middle of the year for degree day and peaking in second half of the year for ABS. Analysis of 34 C. capitata quarantines from 1975 to 2017 in California shows that, for all but two, quarantines were started in the second half of the year, when degree day quarantine lengths are longest and have the highest uncertainty. For a set of hypothetical outbreaks based on these historical quarantines, the ABS produced significantly shorter quarantines than degree day calculations. Overall, ABS quarantine lengths were more consistent than degree day predictions, avoided unrealistically long values, and captured effects of rare events such as cold snaps.

  8. The potential for optical beam shaping of UV laser sources for mass scale quarantine disinfection applications

    Recent events concerning H1N1 "swine flu", have demonstrated to the world the significant potential of rapid increases in death and illness among all age groups and even among the healthy population [1] when a highly infectious influenza virus is introduced. In terms of mass casualties due to a pandemic, preparedness and response planning must be done. One course of action to prevent a pandemic outbreak or reduce the impact of a bioterrorist event is the use of isolation or quarantine facilities. The first level of isolation or quarantine is within the personal residence of the person exposed or infected. In the case where, the specific virus is extremely contagious and its onset of symptoms is rapid and severe, there will be a need for the deployment and setup of larger self contained quarantine facilities. Such facilities are used to house infectious individuals to minimize the exposure of susceptible individuals to contagious individuals, especially when specialized care or treatment is required and during the viral shedding period (5 to 7 days). These types of facilities require non-shared air conditioning, heating and ventilating systems where 100% of air is vented to the outside through a series of disinfection systems and staged filters. Although chemical disinfection is possible, there is a desire to incorporate intense UV radiation as a means to deactivate and disinfect airborne virus within hospital settings and isolated mass scale quarantine facilities. UV radiation is also being considered for disinfection of contaminated surfaces, such as table tops, walls and floors in hospitals and temporary quarantine facilities. In such applications the use of UV bulb technology can create many problems, for instance bulb technology requires numerous bulbs to treat a large volume of air, generates significant heat, uses significant power and does not produce large fluxes of UV light efficiently. This paper provides several methods of creating quarantine level

    The Australian state of Victoria, with 5.2 million residents, enforced home quarantine during a H1N1 pandemic in 2009. The strategy was targeted at school children. The objective of this study was to investigate the extent to which parents' access to paid sick leave or paid carer's leave was associated with (a) time taken off work to care for quarantined children, (b) household finances, and (c) compliance with quarantine recommendations. We conducted an online and telephone survey of households recruited through 33 schools (85% of eligible schools), received 314 responses (27%), and analysed the subsample of 133 households in which all resident parents were employed. In 52% of households, parents took time off work to care for quarantined children. Households in which no resident parent had access to leave appeared to be less likely to take time off work (42% vs 58%, p=0.08) although this difference had only borderline significance. Among parents who did take time off work, those in households without access to leave were more likely to lose pay (73% vs 21%, pparent lost pay due to taking time off work, 42% experienced further financial consequences such as being unable to pay a bill. Access to leave did not predict compliance with quarantine recommendations. Future pandemic plans should consider the economic costs borne by households and options for compensating quarantined families for income losses.

    Trust is often cited as a necessary predecessor of social engagement, and a public-health good. We question those suppositions through analysis of the life histories of lower-income older adults aging in place in Baltimore. These people desired to continue living independently, but also expressed a complex mix of trust and mistrust in their neighbors, neighborhoods, and broader environments. This was the product of interrelated processes of multilevel physical and social changes over time and space - and, we argue, often featured a "healthy mistrust" that pushed participants to pursue personally meaningful forms of social engagement, whether new or continued.

    2016-01-01

    Heat response plans are becoming increasingly more common as US cities prepare for heat waves and other effects of climate change. Standard elements of heat response plans exist, but plans vary depending on geographic location and distribution of vulnerable populations. Because heat events vary over time and affect populations differently based on vulnerability, it is difficult to compare heat response plans and evaluate responses to heat events. This article provides an overview of the Baltimore City heat response plan, the Code Red program, and discusses the city's response to the 2012 Ohio Valley/Mid Atlantic Derecho, a complex heat event. Challenges with and strategies for evaluating the program are reviewed and shared.

    On September 30, 2014, the Bong County health officer notified the county Ebola task force of a growing outbreak of Ebola virus disease (Ebola) in Mawah, a village of approximately 800 residents. During September 9-16, household quarantine had been used by the community in response to a new Ebola infection. Because the infection led to a local outbreak that grew during September 17-20, county authorities suggested community quarantine be considered, and beginning on approximately September 20, the Fuamah District Ebola Task Force (Task Force) engaged Mawah leaders to provide education about Ebola and to secure cooperation for the proposed measures. On September 30, Bong County requested technical assistance to develop strategies to limit transmission in the village and to prevent spread to other areas. The county health team, with support from the Task Force and CDC, traveled to Mawah on October 1 and identified approximately two dozen residents reporting symptoms consistent with Ebola. Because of an ambulance shortage, 2 days were required, beginning October 1, to transport the patients to an Ebola treatment unit in Monrovia. Community quarantine measures, consisting of restrictions on entering or leaving Mawah, regulated river crossings, and market closures, were implemented on October 1. Local leaders raised concerns about availability of medical care and food. The local clinic was reopened on October 11, and food was distributed on October 12. The Task Force reported a total of 22 cases of Ebola in Mawah during September 9-October 2, of which 19 were fatal. During October 3-November 21, no new cases were reported in the village. Involving community members during planning and implementation helped support a safe and effective community quarantine in Mawah.

    To pre-establish an alternative technique to the toxic fumigant, methyl bromide which is the current quarantine measure of agricultural products for export and import, some selected agricultural products, such as chestnut, acorn, red bean and mung bean, were subjected to a preliminary study to confirm the comparative effects of gamma irradiation and MBr fumigant on their disinfestation and quality, thereby preparing the basic data for the practical approach. Current quarantine activities were examined and the related limitations were investigated. Quarantine-related pests were investigated on their radiosensitivity and disinfestation effects by both treatments. The pests in chestnut and acorn, Curculio skkimensis Heller, Curculio dentipes Roelofs, and Dichocrocis punctiferalis Guenee showed an increased mortality when exposed to above 0.5 kGy irradiation, resulting in 100% of mortality three weeks later. Callosobruchus chinensis Linne from both red and mung beans revealed a apparent mortality at around 10 days after irradiation of 1 to 3 kGy. Current fumigation was perfect in its disinfesting capability, but it caused the detrimental effects on physical quality of agricultural produce. Whereas, irradiation doses suitable for controlling the pests did not induce any significant changes in the quality of the samples. (author). 53 refs., 74 figs., 138 tabs.

    Fresh blueberries (Vaccinium spp.) are considered one of the richest sources of phenolic compounds and are appreciated for their high antioxidant capacity. But they are hosts in Argentina of the quarantine pests Ceratitis capitata and Anastrepha fraterculus, and have to be treated to avoid its spreading. Irradiation is being introduced in the Agricultural World trade, increasing exponentially on the last years. In order to guarantee the success of this process, it is required previous to the rutinary treatment, to define the irradiation dose range to be applied. The minimum dose for these pests has been already approved in the IPPC standard 28. The maximum dose depends on the tolerance of the fruit cultivars, maturity, pre-harvest conditions, harvest time, storage conditions, and interactions among these factors. The postharvest quality of Argentina´s blueberry treated with irradiation doses of 150 (generic quarantine dose used for fruit flies) and 300 Gy (to evaluate tolerance) was evaluated. The studies included blueberries from different harvest seasons 2009-2012). Misty, O'Neal and Emeral varieties were chosen, because they represent the biggest volume of exported blueberry from Argentina. The results indicated that irradiation at 150 Gy and 300 Gy did not significantly affect the postharvest quality and slightly improved shelf life of the different blueberries varieties. Therefore, it is possible to use irradiation as an alternative quarantine treatment for Argentina´s blueberries, establishing a dose range appropriate to be applied on a commercial irradiation facility.

    Reverse Innovation has been endorsed as a vehicle for promoting bidirectional learning and information flow between low- and middle-income countries and high-income countries, with the aim of tackling common unmet needs. One such need, which traverses international boundaries, is the development of strategies to initiate and sustain community engagement in health care delivery systems. In this commentary, we discuss the Baltimore "Community-based Organizations Neighborhood Network: Enhancing Capacity Together" Study. This randomized controlled trial evaluated whether or not a community engagement strategy, developed to address patient safety in low- and middle-income countries throughout sub-Saharan Africa, could be successfully applied to create and implement strategies that would link community-based organizations to a local health care system in Baltimore, a city in the United States. Specifically, we explore the trial's activation of community knowledge brokers as the conduit through which community engagement, and innovation production, was achieved. Cultivating community knowledge brokers holds promise as a vehicle for advancing global innovation in the context of health care delivery systems. As such, further efforts to discern the ways in which they may promote the development and dissemination of innovations in health care systems is warranted. Trial Registration Number: NCT02222909 .

    This study used a qualitative approach in which participants were asked to write about their experiences in recruiting older women into either one of two exercise intervention studies that are part of the Baltimore Hip Studies. The sample included 8 researcher nurses all women, White, and 42-53 years of age. Older adults, particularly older women, are less likely to participate in research studies when compared to their younger counterparts. The purpose of this study was to explore the techniques successfully used by research nurses in the Baltimore Hip Studies to recruit older women after hip fracture into exercise intervention studies. Data analysis was performed using basic content analysis (Crabtree & Miller, 1992; Miles & Huberman, 1984) "in vivo" coding (Dowd, 1991), or "grounded" coding (Glaser & Strauss, 1967), which involves using the informants' own words to capture a particular idea. A total of 16 codes were identified and reduced to nine themes. Seven themes focused on techniques that facilitated recruitment: (a) caring for individuals; (b) emphasizing benefits; (c) eliciting support from others; (d) being an expert; (e) using role models; (f) using good timing; and (g) giving good first impressions. The remaining two themes identified barriers to recruitment: (a) time commitment and (b) lack of support. Based on these themes, specific recruitment techniques are recommended. Ongoing research, however, is needed to establish the most effective recruitment procedures with older women.

    The objective of the Syphilis Elimination Project was to decrease the incidence of syphilis in the Hispanic community of Baltimore City through a culturally appropriate health initiative. Both qualitative and quantitative methods were used in the study design. Surveillance data were used to collect testing information. Comparisons at the start and end of the project measured change in individual knowledge about syphilis. Cross-sectional data from interviews with business owners and qualitative comments from outreach workers evaluated perception of program effectiveness. The local health department collected surveillance data. A convenience sample of 63 Hispanic community members, 12 business owners/managers, and 8 outreach workers was utilized throughout the evaluation process. The project was a culturally appropriate approach to health promotion with street and business outreach. Post intervention there was a statistically significant increase in knowledge about syphilis within the Hispanic community and an increase in testing behaviors. The Syphilis Elimination Project was created in response to a marked increase in syphilis in Baltimore among the Hispanic population and a health disparity that existed within the city. It increased community members' knowledge of syphilis and positively influenced testing behaviors.

    Less than 6% of U.S. medical school applicants are African-American. The lack of diversity among physicians, by race as well as other measures, confers a negative impact on the American healthcare system because underrepresented minority (URM) physicians are more likely to practice in underserved communities and deliver more equitable, culturally competent care. MERIT (Medical Education Resources Initiative for Teens) is a nonprofit organization based in Baltimore, Maryland, USA. MERIT prepares URM high school students for health careers by providing a holistic support system for seven consecutive years. The program model, which utilizes weekly Saturday sessions, summer internships, and longitudinal mentoring, is built on four foundational pillars: (1) Ignite the Fire, (2) Illuminate the Path, (3) Create the Toolkit, and (4) Sustain the Desire. Since 2011, MERIT has supported 51 students in the Baltimore City Public School System. For the past two years, 100% (n = 14) of MERIT seniors enrolled in universities, compared to only 20.2% of Baltimore City students overall. While it is too early to know whether MERIT alumni will realize their goals of becoming healthcare professionals, they are currently excelling in universities and over 75% (n = 17) are still planning to pursue graduate degrees in health-related fields. After piloting an effective program model, MERIT now has three key priorities moving forward: (1) Creating a sustainable and thriving organization, (2) increasing the number of scholars the program supports in Baltimore, and (3) expanding MERIT to other cities.

  13. Efficiency of quarantine and self-protection processes in epidemic spreading control on scale-free networks

    Science.gov (United States)

    Esquivel-Gómez, Jose de Jesus; Barajas-Ramírez, Juan Gonzalo

    2018-01-01

    One of the most effective mechanisms to contain the spread of an infectious disease through a population is the implementation of quarantine policies. However, its efficiency is affected by different aspects, for example, the structure of the underlining social network where highly connected individuals are more likely to become infected; therefore, the speed of the transmission of the decease is directly determined by the degree distribution of the network. Another aspect that influences the effectiveness of the quarantine is the self-protection processes of the individuals in the population, that is, they try to avoid contact with potentially infected individuals. In this paper, we investigate the efficiency of quarantine and self-protection processes in preventing the spreading of infectious diseases over complex networks with a power-law degree distribution [ P ( k ) ˜ k - ν ] for different ν values. We propose two alternative scale-free models that result in power-law degree distributions above and below the exponent ν = 3 associated with the conventional Barabási-Albert model. Our results show that the exponent ν determines the effectiveness of these policies in controlling the spreading process. More precisely, we show that for the ν exponent below three, the quarantine mechanism loses effectiveness. However, the efficiency is improved if the quarantine is jointly implemented with a self-protection process driving the number of infected individuals significantly lower.

    Most tropical fruits for export must be treated with an approved quarantine treatment. Three and a half decades of research have demonstrated the efficacy of irradiation as a quarantine treatment in terms of efficiency, effectiveness, and product quality retention. The USFDA and the USDA-APHIS approved irradiation to disinfest fresh foods/fresh papayas in 1986 and 1989, respectively. In early 1995, the Hawaii Department of Agriculture was granted a special permit from USDA-APHIS allowing untreated Hawaiian fruits to be irradiated on the US mainland. The objectives were to gain experience in commercial irradiation as a quarantine treatment and to gather data on shipping and handling procedures, and on product quality. In April 1995, the first shipment of Hawaiian fruit was irradiated at a minimum quarantine dose of 0.25 kGy in an Isomedix plant near Chicago, and then distributed to supermarkets in Illinois and Ohio. Continuous shipments, irradiation, and marketing of various tropical fruits in the US have shown commercial efficacy, quality retention, and excellent consumer acceptance. A commercial e-beam/converted X-ray facility was installed by Titan Corp. on the Island of Hawaii and was operational by late July 2000. Hawaii has become the first place in the world to use irradiation as a quarantine treatment of fruits.

    Disparity between watershed erosion rates and downstream sediment delivery has remained an important theme in geomorphology for many decades, with the role of floodplains in sediment storage as a common focus. In the Piedmont Province of the eastern USA, upland deforestation and agricultural land use following European settlement led to accumulation of thick packages of overbank sediment in valley bottoms, commonly referred to as legacy deposits. Previous authors have argued that legacy deposits represent a potentially important source of modern sediment loads following remobilization by lateral migration and progressive channel widening. This paper seeks to quantify (1) rates of sediment remobilization from Baltimore County floodplains by channel migration and bank erosion, (2) proportions of streambank sediment derived from legacy deposits, and (3) potential contribution of net streambank erosion and legacy sediments to downstream sediment yield within the Mid-Atlantic Piedmont. We calculated measurable gross erosion and deposition rates within the fluvial corridor along 40 valley segments from 18 watersheds with drainage areas between 0.18 and 155 km2 in Baltimore County, Maryland. We compared stream channel and floodplain morphology from lidar-based digital elevation data collected in 2005 with channel positions recorded on 1:2400 scale topographic maps from 1959-1961 in order to quantify 44-46 years of channel change. Sediment bulk density and particle size distributions were characterized from streambank and channel deposit samples and used for volume to mass conversions and for comparison with other sediment sources. Average annual lateral migration rates ranged from 0.04 to 0.19 m/y, which represented an annual migration of 2.5% (0.9-4.4%) channel width across all study segments, suggesting that channel dimensions may be used as reasonable predictors of bank erosion rates. Gross bank erosion rates varied from 43 to 310 Mg/km/y (median = 114) and were

    Personal exposures to particulate and gaseous pollutants and corresponding ambient concentrations were measured for 56 subjects living in Baltimore, Maryland, and 43 subjects living in Boston, Massachusetts. The 3 Baltimore cohorts consisted of 20 healthy older adults (seniors), 21 children, and 15 individuals with physician-diagnosed chronic obstructive pulmonary disease (COPD*). The 2 Boston cohorts were 20 healthy seniors and 23 children. All children were 9 to 13 years of age; seniors were 65 years of age or older; and the COPD participants had moderate to severe physician-diagnosed COPD. Personal exposures to particulate matter with aerodynamic diameters less than 2.5 microm (PM2.5), sulfate (SO(4)2-), elemental carbon (EC), ozone (03), nitrogen dioxide (NO2), and sulfur dioxide (SO2) were measured simultaneously for 24 hours/day. All subjects were monitored for 8 to 12 consecutive days. The primary objectives of this study were (1) to characterize the personal particulate and gaseous exposures for individuals sensitive to PM health effects and (2) to assess the appropriateness of exposure assessment strategies for use in PM epidemiologic studies. Personal exposures to multiple pollutants and ambient concentrations were measured for subjects from each cohort from each location. Pollutant data were analyzed using correlation and mixed-model regression analyses. In Baltimore, personal PM2.5 exposures tended to be comparable to (and frequently lower than) corresponding ambient concentrations; in Boston, the personal exposures were frequently higher. Overall, personal exposures to the gaseous pollutants, especially O3 and SO2, were considerably lower than corresponding ambient concentrations because of the lack of indoor sources for these gases and their high removal rate on indoor surfaces. Further, the impact of ambient particles on personal exposure (the infiltration factor) and differences in infiltration factor by city, season, and cohort were investigated

    Research on efficacy of quarantine treatments for horticultural crops has been conducted in the United States of America by scientists of the U.S. Department of Agriculture, Agricultural Research Service (ARS), and by scientists in various state research organizations for many years. ARS scientists have been investigating effectiveness of fumigation using volatile chemicals such as ethylene dibromide, methyl bromide, phosphine and others; physical methods including cold, heat, modified atmosphere and gamma irradiation; and biological methods such as host susceptibility and host inspection as treatments for commodities infested by fruit flies and other pests. ARS and state scientists are studying possible adverse effects of such treatments on the commodities. This research also involves cooperation with the U.S. Department of Energy and its contractors, Sandia Laboratories, CH 2 M Hill, and Battelle Pacific Northwest Laboratories. (author)

  19. Investigating stakeholders' perceptions of the link between high STD rates and the current Baltimore City Public Schools' sex education curriculum

    Bolden, Shenell L. T.

    The purpose of this exploratory study was to examine key stakeholders' perceptions of the current Baltimore City Public Schools' (BCPS) sex education curriculum and to gain insight into how they believe the curriculum could be modified to be more effective. A mixed methods approach using qualitative and quantitative data collection consisting of a survey, focus group interview, and individual interviews was conducted to gather information on stakeholders' perceptions. The stakeholders included: (1) former students who received their sex education courses in the Baltimore City Public School system (BCPS); (2) teachers in BCPS who were affiliated with the sex education curriculum; (3) health care professionals who screened and/or treated East Baltimore City residents for a sexually transmitted disease (STD) and; (4) one policy maker who was responsible for creating sex education curriculum at the national level. Analysis of the quantitative data from former Baltimore City Public School students revealed a general satisfaction with the current sex education curriculum. However, qualitative data from the same group of stakeholders revealed several changes they thought should be implemented into the program in an effort to improve the current curriculum. Findings from the other groups after qualitative analysis of the interviews suggest three major themes in support of curriculum change: (1) a blended curriculum that integrates both the cognitive and affective learning domains; (2) knowledge of prevention of STD's and pregnancy; and (3) authentic teaching and learning. Results from this study strongly suggest that the Baltimore City Public School system is apathetic to the sexual health needs of students and, therefore, is inadvertently contributing to the high rate of sexually transmitted diseases among young people.

    Female injection drug users {IDU} who report sex with women are at increased risk for HIV and social instability, but it is important to assess whether these disparities also exist according to sexual minority identity rather than behaviorally defined categories. Within a sample of current IDU in Baltimore, about 17% of female study participants (n=307) identified as gay/lesbian/bisexual. In controlled models, sexual minorities were three times as likely to report sex exchange behavior and four times as likely to report a recent STI. Injection risk did not differ significantly, but sexual minority women reported higher prevalence of socio-economic instability, negative health indicators, and fewer network financial, material, and health support resources. There is a need to identify and address socio-economic marginalization, social support, and health issues among female IDUs who identify as lesbian or bisexual. PMID:25504312

    The selection of an incinerator by the University of Maryland at Baltimore was carried out under a demonstration grant from the Department of Energy (DOE). The system selected is a 300 lb per hour dual-chambered, controlled air incinerator. The cost of the unit was $130,000, excluding installation. The interior is lined with high temperature brick rather than a castable refractory. The burners in the upper and lower chambers are ''oversized'' to insure responsive temperature control of 2.5 million Btu/h in the upper chamber and 1.3 million Btu/h in the lower. The prescribed operating temperatures are 1900 to 2100 0 F in the upper chamber and 900 to 1200 0 F in the lower chamber. The system has a rated capacity of 300 lbs/h of type IV, pathological waste, but operational experience has limited our feed rate to 150 lbs/h

    The food environment is associated with obesity risk and diet-related chronic diseases. Despite extensive research conducted on retail food stores, little is known about prepared food sources(PFSs). We conducted an observational assessment of all PFSs(N = 92) in low-income neighborhoods in Baltimore. The most common PFSs were carry-outs, which had the lowest availability of healthy food choices. Only a small proportion of these carry-outs offered healthy sides, whole wheat bread, or entrée salads (21.4%, 7.1%, and 33.9%, respectively). These findings suggest that carry-out-specific interventions are necessary to increase healthy food availability in low-income urban neighborhoods.

  3. Quality of 'Brightwell' and 'Tifblue' blueberries after gamma irradiation for quarantine treatment

    1996-01-01

    Blueberries must be subjected to a quarantine treatment of methyl bromide fumigation when shipped to certain domestic or export markets. The principle insects that inhibit distribution of blueberries are the apple maggot [Rhagoletis pomonella (Walsh)], blueberry maggot (R. mendax Curran), and plum curculio [Conotrachelus nenuphar (Herbst)]. Methyl bromide fumigation is the only approved quarantine treatment for blueberries and it is scheduled to be phased out by the year 2001. Highbush blueberries’ tolerance to low-dose irradiation is cultivar-dependent (Eaton et al., 1970). Two main cultivars grown in Florida, ‘Climax’ and ‘Sharpblue’, will tolerate irradiation up to 0.75 kGy without loss of fruit market quality (Miller et al., 1994a, 1994b, 1995). A 1.0-kGy dose is the maximum allowed (U.S. Food and Drug Administration, 1986) for treatment of fresh fruit or vegetables, and reportedly (personal communications, J. Sharp and G. Hallman) »0.3 kGy is sufficient for control of blueberry insects requiring quarantine certification. Two or three times the minimum dose may, however, be required to assure that the minimum dose is absorbed by all berries during commercial application. Therefore, it is most important to determine the tolerance of berries to irradiation stress. The purpose of this research was to determine the effects of low-dose irradiation on the quality and condition of ‘Brightwell’ and ‘Tifblue’, two major rabbiteye cultivars grown in Georgia. The data were subjected to analysis of variance (P £ 0.05) on a split-block experimental design, with harvest dates for ‘Brightwell’, and randomized sample sets as replications for ‘Tifblue’ berries. The data were tested for the main effect of irradiation dosage on quality attributes

    Phenacoccus solenopsis is an aggressively invasive species that targets agricultural and ornamental plants, thereby threatening the world cotton industry and other crops. P. solenopsis has been listed as a quarantine insect in Europe and China. The utilization of phytosanitary irradiation as a potential treatment for disinfesting agricultural commodities in trade has expanded rapidly in recent years. A reasonable dose of radiation to eliminate P. solenopsis needs to be determined, taking into account the side effects of radiation on agricultural products and the species-specific tolerance of the insect to radiation. We applied radiation ranging from 50 to 200 Gy to P. solenopsis to determine the optimal dose. Both the radiation dose and the developmental stage of the insect were independent variables. Higher doses of radiation or lesser mature insect stages provided more effective treatment. In nymphs, a radiation dose of 100 Gy caused extinction of the irradiated population by disrupting ovary development, while 150 Gy caused 100% mortality. In adults, all tested doses of irradiation did not affect longevity, but we were able to prevent reproduction with high (150 and 200 Gy) doses. In P. solenopsis, a 100 Gy dose of radiation could eliminate the irradiated population in two generations. The mortality curve showed a steep slope beyond 150 Gy; thus, if killing all of the insects in a shorter amount of time is necessary, 200 Gy may be a reasonable dose for the quarantine treatment of the solenopsis mealybug. - Highlights: • Both ‘radiation dose’ and ‘irradiated insect stage’ are important factors. • 100-Gy irradiation could achieve population extinction in two generations. • 200 Gy should be a reasonable dose in the quarantine treatment

    Full Text Available The Shield (FX 2002-08 and The Wire (HBO 2002-08 are two of the most ever critically acclaimed TV-shows and they both can be seen as the finest developed film noir proposals produced in television. The Wire transcends the cop-show genre by offering a multilayered portrait of the whole city of Baltimore: from police work to drug dealing, getting through stevedores’ union corruption, tricks of local politics, problems of the school system and some unethical journalism practices. On the other, The Shield offers a breathtaking cop-show that features in the foreground the moral ambiguity that characterizes the noir genre. Both series display complementary realist strategies (a neorealist aesthetic in The Wire; a cinéma vérité pastiche in The Shield that highlight the importance of city landscape in their narrative. Baltimore and Los Angeles are portrayed not only as a dangerous and ruined physical places, but are also intertwined with moral and political issues in contemporary cities, such as race, class, political corruption, social disintegration, economical disparities, the limitations of the system of justice, the failure of the American dream and so on. The complex and expanded narrative of The Wire and The Shield, as Dimemberg has written for film noir genre, “remains well attuned to the violently fragmented spaces and times of the late-modern world”. Therefore, this article will focus on how The Wire and The Shield (and some of their TV heirs, such as Southland and Justified reflect and renew several topics related to the city in the film noir tradition: the sociopolitical effects of showing the ruins of the centripetal industrial metropolis, the inferences of filming in actual places, the dramatic presence of what Augé coined as “no-places”, the bachelardian opposition between home and city, or the streets as an urban jungle where danger lurks in every corner.

    Addressing record high rates of Chlamydia trachomatis incidence in the United States requires the utilization of effective strategies, such as expedited partner therapy, to reduce reinfection and further transmission. Expedited partner therapy, which can be given as a prescription or medication, is a strategy to treat the sexual partners of index patients diagnosed with a sexually transmitted infection without prior medical evaluation of the partners. There are multiple steps in the prescription-expedited partner therapy cascade, and we sought to identify pharmacy-level barriers to implementing prescription-expedited partner therapy for Chlamydia trachomatis treatment. We used spatial analysis and ArcGIS, a geographic information system, to map and assess geospatial access to pharmacies within Baltimore, MD, neighborhoods with the highest rates of Chlamydia trachomatis (1180.25-4255.31 per 100,000 persons). Expedited partner therapy knowledge and practices were collected via a telephone survey of pharmacists employed at retail pharmacies located in these same neighborhoods. Cost of antibiotic medication in US dollars was collected. Census tracts with the highest Chlamydia trachomatis incidence rates had lower median pharmacy density than other census tracts (26.9 per 100,000 vs 31.4 per 100,000, P barriers to implementing prescription-expedited partner therapy. Although most Baltimore pharmacists were unaware of expedited partner therapy, they were generally receptive to learning about and filling expedited partner therapy prescriptions. This finding suggests the need for wide dissemination of educational material targeted to pharmacists. In areas with limited geographic access to pharmacies, expedited partner therapy strategies that do not depend on partners physically accessing a pharmacy merit consideration.

    Introduction Pre-exposure prophylaxis (PrEP) safely and effectively prevents HIV in populations at high risk, including men who have sex with men (MSM). PrEP scale-up depends upon primary care providers and community-based organizations (CBOs) sharing PrEP information. This study aimed to determine whether healthcare provider or CBO contact was associated with PrEP awareness among Baltimore MSM. Methods This study used 2014 Baltimore MSM National HIV Behavioral Surveillance data, which included data on health care, HIV and sexually transmitted infection testing, and receipt of condoms from CBOs. In 2015, associations were estimated between healthcare contacts and PrEP awareness through logistic regression models controlling for age, race, and education and clustering by venue. Comparative analyses were conducted with HIV testing as outcome. Results There were 401 HIV-negative participants, of whom 168 (42%) were aware of PrEP. Visiting a healthcare provider in the past 12 months, receiving an HIV test from a provider, and having a sexually transmitted infection test in the past 12 months were not significantly associated with PrEP awareness. PrEP awareness was associated with being out to a healthcare provider (OR = 2.97, 95% CI=1.78, 4.96, p<0.001); being tested for HIV (OR=1.50, 95% CI = 1.06, 2.13, p = 0.023); and receiving condoms from an HIV/AIDS CBO (OR = 2.59, 95% CI = 1.43, 4.64, p = 0.001). By contrast, HIV testing was significantly associated with most forms of healthcare contact. Conclusions PrEP awareness is not associated with most forms of healthcare contact, highlighting the need for guidelines and trainings to support provider discussion of PrEP with MSM. PMID:27662698

    The main objective of this paper is to understand the role of the family on the sexual experiences of adolescents from urban, disadvantaged settings in Baltimore and Johannesburg. Data were collected as part of the WAVE study, a global study of disadvantaged youth in five cities. Qualitative data were based on key informant interviews, a Photovoice exercise, community mapping, focus groups and in-depth interviews with adolescents. Quantitative data were gathered from an ACASI survey that was administered to approximately 450-500 adolescents per site. Results from the qualitative data revealed that while parents were viewed as important sources of information for sexual and reproductive health, they were often not present in the adolescents' lives. This lack of parental presence was perceived to result in adolescents feeling an overall lack of adult support and guidance. The impact of parental presence and support on adolescent sexual experience was further examined from the quantitative data and revealed a complex picture. In both Baltimore and Johannesburg, female adolescents who were raised by other relatives were less likely to report having had sex compared to those raised by two biological parents, which was not observed for males. In Johannesburg, female adolescents who were paternal orphans were less likely to have had sex compared to non-orphans; the opposite was true among males. Finally, in both sites, female adolescents who had been exposed to violence were more likely to have had sex compared to those who had not; for males, there was no significant relationship. The study demonstrates the powerful influence of both context and gender for understanding the influences of the family on adolescent sexual behaviors. Programs aiming to reduce adolescent sexual risk behaviors the need to understand the complex influences on risk behaviors in different settings and in particular, the role of mothers and fathers. Prevention strategies need to also understand

    The Peach rosette mosaic virus (PRMV) is a plant pathogen of the genus Nepovirus, and has been designated as a controlled quarantine virus in Korea. In this study, a specific reverse transcription (RT)-PCR marker set, nested PCR marker set, and modified-plasmid positive control were developed to promptly and accurately diagnose PRMV at plant-quarantine sites. The final selected PRMV-specific RT-PCR marker was PRMV-N10/C70 (967 bp), and the nested PCR product of 419 bp was finally amplified. The modified-plasmid positive control, in which the SalI restriction-enzyme region (GTCGAC) was inserted, verified PRMV contamination in a comparison with the control, enabling a more accurate diagnosis. It is expected that the developed method will continuously contribute to the plant-quarantine process in Korea.

    Carambolas infested with the Caribbean fruit fly Anastrepha suspensa (Loew), eggs and larvae were exposed to ionizing gamma radiation. Probit 9 was estimated to be 22.95 Gy (95% fiducial limits 16.68 Gy - 49.73 Gy). Over 100,000 immature A. suspensa infesting carambolas were treated at 50 Gy with no adult survivors. This dose did not cause any observable damage to the fruit. The 50 Gy dose satisfies quarantine requirements for treatment of fruits exposed from fruit fly infested areas. (author) [es

    1985-01-01

    Treatment of Queensland fruit fly, Dacus tryoni, eggs, and larvae with a dose of 75 Gy of radiation prevents the emergence of adult flies, although many insects develop to the pupal stage. This has been demonstrated with large numbers of insects present in oranges and avocados, two entirely different fruit types. The aim of such a commodity treatment should be to prevent the establishment of an insect pest in a new environment. This low-dose treatment should, therefore find acceptance with quarantine authorities, since the nonemergence of adult files effectively breaks the life cycle of the insect. This paper provides details of the experimental approach and the results of these efficacy studies

    1994-01-01

    Radiation is one of the techniques used to effectively rid fresh produce of insect pests and efficacy of radiation dose on food is measured by a probit 9 (99.9968% mortality) quarantine security. Present of suitable biochemical markers for irreversible radiation injury in insect pests could be used as convincing proofs of the efficacy of radiation dose. A biochemical marker (designated Gs-protein) for radiation injury in Oriental fruit fly, Dacus dorsalis, was detected in the SDS-PAGE profile of two-day old pupae and adult insect stage. Gs-protein is not observed in larvae and eggs. An apparent molecular weight of 109 kDa was calculated. A tyrosinase enzyme activity was observed in the soluble fraction of pupal total homogenate and SDS-PAGE-isolated Gs-protein; however, no tyrosinase activity was measured in irradiated sample. The optical absorbance of the soluble fraction from unirradiated pupal total homogenate measured at 360 nm was found to increase with time. From the results of the studies, the apparent loss of Gs-protein in irradiated larvae is likely the result of loss of melanization capability in irradiated larvae which is linked to the absence of tyrosinase enzyme. The data presented seems to establish the role of Gs-protein as a biomarker for gamma-irradiation induced deactivation of pupal development and as a convenient indicator of the effectiveness of gamma radiation as a quarantine treatment.

    The U.S. Department of Agriculture in February 2012 approved the import of fresh pomegranates subjected to irradiation as a quarantine procedure with a minimum absorbed dose of 0.4kGy against different pests. This study evaluated the application of different gamma-irradiation doses (0.4, 1, and 2kGy) in fresh pomegranate fruits and their effect on the chemical and sensory characteristics. The total soluble solids, titratable acidity, and pH values remained unaffected up to 1kGy treatment. Irradiation caused a significant decrease in the total anthocyanins and phenolic content. A strong positive correlation was observed among the antioxidant activities, total phenolics and anthocyanin contents. In general, a stronger preference was shown by sensory panelists for the juice from irradiated fruits. This study provides research-based information about the application of irradiation as a quarantine disinfestation treatment to enhance the marketing and consumer acceptance of pomegranates.

    The citrus black fruit fly (Aleurocanthus woglumi Ashby) is an important pest of citrus originated in Southeast Asia and its first record in the new world was in Jamaica in 1913. In Brazil, it was detected in 2001 in the state of Para and more recently it was detected in Sao Paulo in 2008. This pest that attacks over 300 species of plants, but its main host are citrus. It is an A2 quarantine pest, because it is not spread throughout the country. The objective of this study was to test doses of 0 (control), 25, 50, 75, 100, 125, 150, 175 and 200 Gy of gamma irradiation for disinfection of eggs of the citrus black fruit fly in leaves of citrus plants. Treatment consisted of 5 replicates with 60 eggs each. Evaluations were performed in the following periods: 1, 3, 5, 7 and 10 days after irradiation. Under the conditions assayed, it could be concluded that a dose of 200 Gy caused 100% mortality of Aleurocanthus woglumi Ashby eggs and could be recommended as a successful quarantine processing against infested plants.

    The world now faces the dreadful possibility of biological weapons attacks by terrorists. Healthcare systems would have to cope with such emergencies should all preemptive measures fail. Information gained from the Global Mercury exercise and the SARS outbreak has shown that containing an outbreak at the start is more effective than reacting to it once it has spread and that containment should be treated both nationally and internationally. On the national level this entails developing rapid and effective methods to detect and identify infected cases, and implementing isolation and control measures to lower the risk of further transmission of the disease while assuring the safety of medical teams and laboratory workers. Strategic contingency plans should incorporate well-defined procedures for hospitalization and isolation of patients, providing regional backup of medical personnel and equipment and maintaining close cooperation between the various bodies in the healthcare system. Quarantine is an effective containment measure, especially if voluntarily imposed. Modern communication systems can help by sending professional teams timely instructions and providing the public with information to reduce panic and stress during quarantine procedures. Informing the public poses a dilemma: finding a balance between giving advance warning of an imminent epidemic outbreak and ascertaining the likelihood of its occurrence. Containment of international bioterrorist attacks depends entirely on close international cooperation to implement national and international strategic contingency plans with free exchange of information and recognition of procedures.

  9. Efficacy of irradiation vs thermal methods as quarantine treatments for tropical fruits

    Ionizing radiation can be effectively applied to fruits and vegetables for several purposes. The most feasible and potentially useful application is probably for disinfestation as a quarantine treatment. All stages of a fruit fly will become sterile upon being irradiated at a minimum dose of 0.15 kGy, the dose level approved by the USDA in January 1989 for treating Hawaiian papayas as a quarantine procedure. Research on irradiation of several tropical fruits such as papayas, mangoes, lychees showed that the chemical, sensory and nutrient qualities of these fruits were well retained at 1.0 kGy, and the fruits would ripen normally or slightly delayed. Irradiation studies have proved the efficacy of the process to disinfest tropical fruits of fruit flies. Market test of irradiated Hawaiian papayas in 1987 showed that consumers preferred irradiated papayas over hot water treated papayas by 11 to 1. Thus the only hurdle to overcome in using irradiation for tropical fruits is to convince the consumers that irradiated fruits are wholesome and safe for human consumption, which has been proven with scientific data obtained during the past three decades, and further proven with the marketing of irradiated fruits in the U.S.A. since early 1992.

    Cut flower, an important export commodity of Malaysia in international trade, is often subjected to infestation by various pests such as mites, scales and thrips. The use of low ionizing radiation has been suggested as an alternative to methyl bromide fumigation, the current pest disinfestations treatment for cut flower but which is being phased out due to environmental concerns. The criterion for efficacy of radiation as a quarantine treatment will be inability of treated mites to reproduce at a new location rather than causing immediate mortality. A dose of 200 Gy prevented reproduction in female adult of Tetranychus piercie by inducing sterility while a much higher dose of 5 kGy is required to produce instant mortality. Based on the results obtained gamma irradiation of dose range 300-500 Gy may be applied as a quarantine treatment for Tetranycus piercie. However, this dose range is only suitable for chrysanthemum (in 4% sucrose solution) but not roses, carnations and orchids which showed phytotoxic symptoms at dose range of 100-400 Gy. (Author)

    Full Text Available To detect five plant viruses (Beet black scorch virus, Beet necrotic yellow vein virus, Eggplant mottled dwarf virus, Pelargonium zonate spot virus, and Rice yellow mottle virus for quarantine purposes, we designed 15 RT-PCR primer sets. Primer design was based on the nucleotide sequence of the coat protein gene, which is highly conserved within species. All but one primer set successfully amplified the targets, and gradient PCRs indicated that the optimal temperature for the 14 useful primer sets was 51.9°C. Some primer sets worked well regardless of annealing temperature while others required a very specific annealing temperature. A primer specificity test using plant total RNAs and cDNAs of other plant virus-infected samples demonstrated that the designed primer sets were highly specific and generated reproducible results. The newly developed RT-PCR primer sets would be useful for quarantine inspections aimed at preventing the entry of exotic plant viruses into Korea.

    Cut flower, an important export commodity of Malaysia in international trade, is often subjected to infestation by various pests such as mites, scales and thrips. The use of low ionising radiation has been suggested as an alternative to methyl bromide fumigation, the current pest disinfestation treatment for cut flower but which is being phased out due to environmental concerns. The criterion for efficacy of radiation as a quarantine treatment will be the inability of treated mites to reproduce at a new location rather than causing immediate mortality. Irradiating red spider mite Tetranychus piercie at a dose of 300 and 400 Gy produced sterile female adults from irradiated protonymph and deutonymph respectively. A lower dose of 200 Gy induced sterility in female adults developed from the less immature stages of irradiated egg and larva. Deteriorating effects caused by irradiation treatment were reflected in immatures by their reduced emergence rate/mortality in subsequent developmental stages. A dose of 240 Gy prevented reproduction in female adult of T piercie by inducing sterility while a much higher dose of 5 kGy is required to produce instant mortality. Based on the results obtained gamma irradiation of dose range 300-400 Gy may be applied as a quarantine treatment against Tetranychus piercie. However, this dose range is only suitable for chrysanthemum (in 4% sucrose solution) but not roses, carnations and orchids which showed phytotoxic symptoms at dose range of 100-300 Gy

    2015-01-01

    Disparity between watershed erosion rates and downstream sediment delivery has remained an important theme in geomorphology for many decades, with the role of floodplains in sediment storage as a common focus. In the Piedmont Province of the eastern USA, upland deforestation and agricultural land use following European settlement led to accumulation of thick packages of overbank sediment in valley bottoms, commonly referred to as legacy deposits. Previous authors have argued that legacy deposits represent a potentially important source of modern sediment loads following remobilization by lateral migration and progressive channel widening. This paper seeks to quantify (1) rates of sediment remobilization from Baltimore County floodplains by channel migration and bank erosion, (2) proportions of streambank sediment derived from legacy deposits, and (3) potential contribution of net streambank erosion and legacy sediments to downstream sediment yield within the Mid-Atlantic Piedmont.We calculated measurable gross erosion and deposition rates within the fluvial corridor along 40 valley segments from 18 watersheds with drainage areas between 0.18 and 155 km2 in Baltimore County, Maryland. We compared stream channel and floodplain morphology from lidar-based digital elevation data collected in 2005 with channel positions recorded on 1:2400 scale topographic maps from 1959–1961 in order to quantify 44–46 years of channel change. Sediment bulk density and particle size distributions were characterized from streambank and channel deposit samples and used for volume to mass conversions and for comparison with other sediment sources.Average annual lateral migration rates ranged from 0.04 to 0.19 m/y, which represented an annual migration of 2.5% (0.9–4.4%) channel width across all study segments, suggesting that channel dimensions may be used as reasonable predictors of bank erosion rates. Gross bank erosion rates varied from 43 to 310 Mg/km/y (median = 114) and

    2002-01-01

    Ceratitis capitata is a quarantine pest. Spanish citrus exports to countries such as the USA or Japan are subjected to a mandatory quarantine treatment consisting of exposure of fruits to a low temperatures. Some citrus (''Fino'' lemon, ''Fortune'' mandarin) are very sensitive to this kind of treatment and can not be treated this way. Therefore, alternative treatments are necessary. In this study, high energy electrons were investigated as an alternative quarantine treatment against C. capitata in citrus. Survival of the different instars (egg to old pupae) of C. capitata reared in an artificial medium was assessed when exposed to different doses between 0 and 1 kGy. Both pupariation and adult emergence were almost prevented at 0.25 kGy, and no viable adults were obtained at 0.50 kGy. When artificially infested fruits (in both ''Fino'' lemon and ''Fortune'' mandarin) were exposed to 1 kGy, 100% mortality was obtained. Finally, quality (texture, color index, maturity index, juice yield, ethanol and acetaldehyde contents, physiological alterations and organoleptic characteristics) of irradiated (1 kGy) and non irradiated fruit were compared. High energy electron irradiation resulted in unacceptable damage to ''Fortune'' mandarin, but quality of ''Fino'' lemon resulted unaltered even when evaluated one month after irradiation. Therefore high energy electrons could be a useful alternative to cold quarantine treatment for ''Fino'' lemons. (author) [es

    Many individuals with HIV in the USA are unaware of their diagnosis, and therefore cannot be engaged in treatment services, have worse clinical outcomes and are more likely to transmit HIV to others. Mobile van testing may increase HIV testing and diagnosis. Our objective was to characterise risk factors for HIV seroconversion among individuals using mobile van testing. A case cohort study (n=543) was conducted within an HIV surveillance dataset of mobile van testing users with at least two HIV tests between September 2004 and August 2009 in Baltimore, Maryland. A subcohort (n=423) was randomly selected; all additional cases were added from the parent cohort. Cases (n=122 total, two from random subcohort) had documented seroconversion at the follow-up visit. A unique aspect of the analysis was use of Department of Corrections data to document incarceration between the times of initial and subsequent testing. Multivariate Cox proportional hazards models were used to compare HIV transmission risk factors between individuals who seroconverted and those who did not. One hundred and twenty-two HIV seroconversions occurred among 8756 individuals (1.4%), a rate higher than that in Baltimore City Health Department's STD Clinic clients (1%). Increased HIV seroconversion risk was associated with men who have sex with men (MSM) (HR 32.76, 95% CI 5.62 to 191.12), sex with an HIV positive partner (HR 70.2, 95% CI 9.58 to 514.89), and intravenous drug use (IDU) (HR 5.65, 95% CI 2.41 to 13.23). HIV testing is a crucial first step in the HIV care continuum and an important HIV prevention tool. This study confirmed the need to reach high-risk populations (MSM, sex with HIV-positive individuals, individuals with IDU) and to increase comprehensive prevention services so that high-risk individuals stay HIV uninfected. HIV testing in mobile vans may be an effective outreach strategy for identifying infection in certain populations at high risk for HIV. © Article author(s) (or

  5. Implications of the Baltimore Rail Tunnel Fire for Full-Scale Testing of Shipping Casks

    International Nuclear Information System (INIS)

    Halstead, R. J.; Dilger, F.

    2003-01-01

    The U.S. Nuclear Regulatory Commission (NRC) does not currently require full-scale physical testing of shipping casks as part of its certification process. Stakeholders have long urged NRC to require full-scale testing as part of certification. NRC is currently preparing a full-scale casktesting proposal as part of the Package Performance Study (PPS) that grew out of the NRC reexamination of the Modal Study. The State of Nevada and Clark County remain committed to the position that demonstration testing would not be an acceptable substitute for a combination of full-scale testing, scale-model tests, and computer simulation of each new cask design prior to certification. Based on previous analyses of cask testing issues, and on preliminary findings regarding the July 2001 Baltimore rail tunnel fire, the authors recommend that NRC prioritize extra-regulatory thermal testing of a large rail cask and the GA-4 truck cask under the PPS. The specific fire conditions and other aspects of the full-scale extra-regulatory tests recommended for the PPS are yet to be determined. NRC, in consultation with stakeholders, must consider past real-world accidents and computer simulations to establish temperature failure thresholds for cask containment and fuel cladding. The cost of extra-regulatory thermal testing is yet to be determined. The minimum cost for regulatory thermal testing of a legal-weight truck cask would likely be $3.3-3.8 million

    Renal disease has been associated with greater risk of dementia and greater cognitive impairment. However, the relationship of lower renal function with long-term decline in specific domains of cognitive function remains unclear among community-dwelling, non-demented individuals. Stroke- and dementia-free participants (n = 2,116) were enrolled in the Baltimore Longitudinal Study of Aging, a community-based, prospective, longitudinal study. Renal function was estimated by the inverse of serum creatinine adjusted for age, sex and race and (in sensitivity analyses) estimated glomerular filtration rate (eGFR) using the MDRD formula. Outcome measures were changes in scores on 6 cognitive tests encompassing a range of cognitive functions, measured at 2-year intervals. Mixed-effects regression models examined the longitudinal relations of renal function with cognitive functions after adjusting for demographics, comorbidity and other potential confounders. Mean age at initial testing was 53.9 years (SD 17.1), and 94 participants (4.4%) had an eGFR age, longitudinal increases in creatinine concentrations were associated with more rapid decline in performance on several cognitive measures, including the learning slope of the California Verbal Learning Test, a test of verbal learning (p renal function independently associated with greater long-term declines in visual memory and verbal memory and learning. © 2015 National Institutes of Health (NIH).

    Full Text Available In this article, we explore the relationship between public recreation policy and planning and the transformation of urban governance in the context of the Police Athletic League centers in Baltimore, Maryland. In light of contemporary discussions of the role of youth programs for sport and physical activity within post-industrial cities, the origination, development, and eventual demise of Baltimore’s network of Police Activity League centers is an instructive, if disheartening, saga. It illustrates the social and political rationales mobilized in justifying recreation policy and programming, the framing of sport and physical activity as preventative measures towards crime and juvenile delinquency, and the precarity of such initiatives given the efficiency-driven orthodoxies of neoliberal urban entrepreneurialism (Harvey, 1989. This analysis emphasizes how the PAL centers were designed to ‘fill the void’ left by a declining system of public recreation, thereby providing an example of a recreation program as part of the “social problems industry” (Pitter & Andrews 1997.

    Supermarket-based interventions are one approach to improving the local food environment and reducing obesity and chronic disease in low-income populations. We implemented a multicomponent intervention that aimed to reduce environmental barriers to healthy food purchasing in a supermarket in Southwest Baltimore. The intervention, Eat Right-Live Well! used: shelf labels and in-store displays promoting healthy foods, sales and promotions on healthy foods, in-store taste tests, increasing healthy food products, community outreach events to promote the intervention, and employee training. We evaluated program implementation through store environment, taste test session, and community event evaluation forms as well as an Employee Impact Questionnaire. The stocking, labeling, and advertising of promoted foods were implemented with high and moderate fidelity. Taste test sessions were implemented with moderate reach and low dose. Community outreach events were implemented with high reach and dose. Supermarket employee training had no significant impact on employees' knowledge, self-efficacy, or behavioral intention for helping customers with healthy purchasing or related topics of nutrition and food safety. In summary, components of this intervention to promote healthy eating were implemented with varying success within a large supermarket. Greater participation from management and employees could improve implementation. © 2015 Society for Public Health Education.

    The Baltimore Therapeutic Equipment (BTE) work simulator is routinely used by occupational therapists in functional capacity evaluation. Currently, there is a lack of normative data for various attachments on this instrument. The purposes of this study were to (a) establish norms for the biomechanical and physiological responses during three tasks on the BTE work simulator, namely, wheel-turn, push-pull, and overhead-reach; (b) compare these responses during the three tasks, and (c) examine the interrelationships of these responses during the tasks. Twenty healthy men completed five testing sessions: (a) task familiarization on the BTE work simulator to identify the work intensity, which was perceived as hard on the Borg scale; (b) an incremental arm ergometer exercise test to determine their peak oxygen uptake (pVO2) and peak heart rate (pHR); and (c) one of the three tasks on the BTE work simulator for 4 min in each of the next three sessions. Analysis of variance indicated that torque, work, and power during the overhead-reach were significantly higher (p = .000) compared with the wheel-turn and push-pull tasks. However, no significant differences (p > .05) were observed among the tasks for the VO2 and HR, which were approximately 50% and 70% of pVO2 and pHR respectively. Although there was a significant relationship (p batteries, and that there is no consistent relationship between cardiorespiratory fitness and performance of various tasks on the BTE work simulator.

    Fires and burns are a leading cause of unintentional injury death in the USA. Although it has been anecdotally reported that vacant dwellings are at a higher risk for fire, the association between vacancy and fire risk at the individual household level has not been empirically measured. In this cross-sectional study, geocoded residential vacant properties (VP) and fire events are analysed in Baltimore City at the census tract level and the individual household level. On average, a 10% increase in the proportion of vacancies in a census tract was associated with a 9.9% increase in fires (95% CI: 5% to 15%). Random-effects Poisson models, controlling for housing and neighbourhood conditions, found contagion effects. The risk of fire in an occupied dwelling increased by 8% (95% CI: 1% to 10%) for every vacant structure within 10 m, and the risk of fire decreased by half (95% CI: 45% to 62%) for every km between an occupied dwelling and vacant building. Close proximity to VP was associated with trash fires within dwellings (p=0.039) and structure fires (p=0.012). We believe that this is the first study to demonstrate increased risk posed by nearby VP at the household level, confirming earlier ecological analyses of the role of VP as strong correlates of home fires. Measurement of this risk can motivate property owners, policy makers and insurers to invest in risk reduction measures that include building maintenance and trash removal.

    The commercially packed samples of raisins, dried figs and dried apricots were irradiated using doses in the range of 0.5-1.0 kGy for disinfestation and 0.5-5.0 kGy for sensory analysis with the dose rate ranging from 1.44 to 1.92 kGy/h. Pests on dried fruits were evaluated after 0, 1, 2 and 3 months of storage for irradiated dried figs and 1, 3, 6 and 12 months of storage for raisins and dried apricots. Sensory analysis of dried figs, dried apricots and raisins were carried out after 0, 1, 3, 6 and 12 months of storage. The results indicated that radiation processing at low doses (∼1.0 kGy) is an effective post-harvest treatment and quarantine control for these products with no adverse effects on sensory (marketing) attributes

    In many countries strict phytosanitary controls have been established to prevent the entry of foreign insect species. The recent interdiction of ethylene dibromide fumigation in USA led to the search of new methods of quarantine control among which irradiation was considered as the more convenient. In different countries such as USA, Australia, New Zeland, studies were conducted to determine the dose of irradiation efficient for controlling different insect species and to verify that irradiation had no noxious effect on the fruits. At the present time the papaya harvested in Hawaii and irradiated against fruit flies are allowed to enter in the continent of USA. In France the irradiation of apples against Leucoptera malifoliella is under study to promote the exportation of apples to America [fr

    The objectives of this study were to evaluate effect of three dosages of ionizing radiation in combination with cold storage (0-2 0 C), and the effect of cold storage without irradiation, establishing time curves for eclosion of eggs and mortality of juvenile and adult stages, and adult oviposture. An experimental Cs-137 Brookhaven Portable Cesium Development Irradiator (BPCDI N. 3) at the Chilean Nuclear Energy Commission, located in the La Reina Commune of Santiago, Chile, was used at dosages of 0.500, 1.000, and 1,500 Gy (with a dosage rate of 28.95 Gy/min), combined with pretreatment cold (0-2 0 C) during 24 h, and 15 days of cold storage postirradiation, to simulate the duration of a grape shipment to the U.S., onto 1-4 and 1-4 and ≥ 4 day-old eggs, juveniles and adult stages. The initial stages of development were more susceptible to radiation when combined with cold storage. The mortality of both egg development stages, juveniles and adults, with dosages from 500-1.500; 1.000-1.500; and 1500 Gy, respectively, satisfied the probity 9 (99.9968%) quarantine security level requirement. The few survivors from treated juveniles and adults were unable to continue their cycle, and did not present quarantine risk. All dosages used produced 100% mortality. Apparently, cold storage has a synergic effect when used in combination with radiation. Cold storage of stages not irradiated somewhat the population dynamics. (author). 58 refs, 24 figs, 12 tabs

    The black flower thrips, Frankliniella australis (Morgan), a Chilean species, causes quarantine rejections of fresh fruits for export. Today, fumigation with CH3Br is efficient to avoid these rejections, but is questioned because it affects the ozone layer, irradiation of foods being an alternative. The effect of gamma irradiation was studied in the laboratory on F. australis adults, at dosages of 250, 500, 750, and 1000 Gy, followed by storage at 0-5 deg C to simulate shipping conditions. Mortality immediately after irradiation was low (1.5 to 22.3% at 250 and 1000 Gy, respectively), but increased an hour later (15.8, 33.4, 44.5, and 51.7% with 250, 500, 750, and 1000 Gy, respectively). In this evaluation, mortality with the greatest dosage was significantly larger than with 500 and 250 Gy, while results with 750 and 500 Gy were not different between them but different with the smallest dosage. At 24 hours, mortality with all dosages surpassed 91%, although only that at 1000 Gy was significantly greater than at 250 Gy. At day 4th (96 hours) there was at least 98.8% mortality for the irradiation treatments, with significant differences with the control, which then presented only 12.8% mortality. Using logit regression with results up to day 4, a probit 9 (LD99.9968) for adults was estimated at 188 Gy. This dosage is slightly less to those indicated in the literature for control of other thrips, which may be explained because of the combined use of cold storage, although more studies are necessary of this technology under commercial conditions to verify its applicability for quarantine control of F. australis.

    This work was carried out to evaluate the effect of thermal treatments (vapour heat and hot water) and irradiation on Ceratitis capitata eggs and larvae (first, second and third instars), in 'Valencia' oranges; the relation between temperature and exposition time to vapour heat and hot water on fruit fly immature; the relation among the different doses of radiation on fruit fly immature and evaluate the effect of the treatments (thermal treatments and irradiation) on the chemical composition of the fruits. It was evaluated the heat absorption and loose of heat by the fruit. For thermal treatments it was used temperatures of 44 and 46 deg C for 15,30,60, 90 and 120 minutes and a control. For irradiation were used the doses: 10,20, 30, 40, 50, 100, 150 and 200 Gy. By the results obtained it is possible to conclude that: to the control of eggs and larvae (first, second and third instars) the treatment with vapour heat was less efficient than the hot water treatment; the thermal treatments of C. capitata eggs and larvae (first and second and third instars) can be recommended with vapor heat at 46 deg C at 152.2 minutes or with hot water at 46 deg C at 84.8 minutes, achieving the quarantine request; third instar larvae are more tolerant to the thermal and irradiation treatments; the treatment with irradiation can be recommended for quarantine treatment of ali immature stages evaluated with the dose of 72.88 Gy; the dose of 50 Gy causes sterility to the adults emerged from ali immature stages irradiated; treatments do not cause any change in the chemical proprieties in the orange fruits var.

    Full Text Available Invasions by pest insects pose a significant threat to agriculture worldwide. In the case of Ceratitis capitata incursions on the US mainland, where it is not officially established, repeated detections are followed by quarantines and treatments to eliminate the invading population. However, it is difficult to accurately set quarantine duration because non-detection may not mean the pest is eliminated. Most programs extend quarantine lengths past the last fly detection by calculating the amount of time required for 3 generations to elapse under a thermal unit accumulation development model (“degree day”. A newer approach is to use an Agent-Based Simulation (ABS to explicitly simulate population demographics and elimination. Here, predicted quarantine lengths for 11 sites in the continental United States are evaluated using both approaches. Results indicate a strong seasonality in quarantine length, with longer predictions in the second half of the year compared with the first; this pattern is more extreme in degree day predictions compared with ABS. Geographically, quarantine lengths increased with latitude, though this was less pronounced under the ABS. Variation in quarantine lengths for particular times and places was dramatically larger for degree day than ABS, generally spiking in the middle of the year for degree day and peaking in second half of the year for ABS. Analysis of 34 C. capitata quarantines from 1975 to 2017 in California shows that, for all but two, quarantines were started in the second half of the year, when degree day quarantine lengths are longest and have the highest uncertainty. For a set of hypothetical outbreaks based on these historical quarantines, the ABS produced significantly shorter quarantines than degree day calculations. Overall, ABS quarantine lengths were more consistent than degree day predictions, avoided unrealistically long values, and captured effects of rare events such as cold snaps.

    Fresh horticultural produce from tropical and sub-tropical areas often harbours insects and mites and are quarantined by importing countries. Such commodities cannot gain access to countries which have strict quarantine regulations such as Australia, Japan, New Zealand and the United States of America unless treated by an approved method/procedure to eliminate such pests. Current approved methods include fumigation by methyl bromide, hot water dip, vapour heat, dried heat and irradiation. Methyl bromide is being phased out globally under the Montreal Protocol in view of its strong ozone depleting properties. Countries such as the USA and those of the European Union are required to phase out the production of this chemical by the year 2005. Among other phytosanitary treatments, irradiation appears to have an edge as it is more versatile in controlling various pests and causes insignificant changes in quality of the treated products. The CRP on Irradiation as a Quarantine Treatment of Mites, Nematodes and Insects other than Fruit Flies, in operation between 1992 and 1997, attempted to fill the gap of information on the effectiveness of irradiation against other quarantine pests. Significant data were generated by this CRP to demonstrate that a minimum dose of between 200 and 400 Gy would render a number of non-fruit fly insects and mites sterile, thus meeting quarantine requirements. However, only a limited species of insects and mites were studied. Additional data are required to provide conclusive evidence that such a dose would render most, if not all, species of non-fruit fly insects and mites sterile. Plant parasitic nematodes appear to be resistant to irradiation as the dose required to render them sterile would cause damage to fresh horticultural commodities. Irradiation would be a useful quarantine treatment against this pest only for durable commodities such as pot soil, wood products, etc. This publication presents the research results of the CRP presented

    Daitao Zhang

    Full Text Available As the pandemic (H1N1 2009 progressed, the Ministry of Health of China advised cases with mild symptoms to remain home for isolation and observation, which may have increased the risk for infection among other household members. Describing the transmission characteristics of this novel virus is indispensable to effectively controlling the spread of disease; thus, the aim of this study was to assess risk factors associated with household transmission of pandemic H1N1 from self-quarantined patients in Beijing, the capital city of China. A 1:2 case-control study with 54 case households and 108 control households was conducted between August 1 and September 30, 2009 in Beijing. Cases were households with a self-quarantined index patient and a secondary case, while controls were households with a self-quarantined index patient and a close contact. Controls were also matched to cases for sex and age of index case-patient. A structured interview guide was used to collect the data. Conditional logistical models were employed to estimate Odds Ratios (OR with 95% confidence intervals (95% CI. Results indicated that higher education level (OR 0.42; 95% CI 0.22-0.83, sharing room with an index case-patient (OR 3.29; 95%CI 1.23-8.78, daily room ventilation (OR 0.28; 95%CI 0.08-0.93, and hand washing ≥ 3/d (OR 0.71; 95%CI 0.48-0.94 were related to the household transmission of pandemic H1N1 from self-quarantined patients. These results highlight that health education, as well as the quarantine of the index case-patient immediately after infection, frequent hand hygiene, and ventilation are critical to mitigating household spread of pandemic H1N1 virus and minimizing its impact. Household contacts should be educated to promote these in-home practices to contain transmission, particularly when household members are quarantined at home.

    To determine the association between personality domains and 11-year cognitive decline in a sample from a population-based study. Data from Waves 3 (1993-1996) and 4 (2003-2004) of the Baltimore cohort of the Epidemiologic Catchment Area (ECA) study were used for analyses. The sample included 561 adults (mean age ± SD: 45.2 ± 10.78 years) who completed the NEO Personality Inventory-Revised prior to Wave 4. Participants also completed the Mini-Mental State Examination (MMSE) and immediate and delayed word recall tests at Wave 3, and at Wave 4, 10.9 ± 0.6 years later. In models adjusted for baseline cognitive performance, demographic characteristics, medical conditions, depressive symptoms, and psychotropic medication use, each 10-point increase in Neuroticism T-scores was associated with a 0.15-point decrease in MMSE scores (B = -0.15, 95% confidence interval [CI]: -0.30, -0.01), whereas each 10-point increase in Conscientiousness T-scores was associated with a 0.18-point increase on the MMSE (B = 0.18, 95% CI: 0.04, 0.32) and a 0.21-point increase in immediate recall (B = 0.21, 95% CI: 0.003, 0.41) between baseline and follow-up. Findings suggest that greater Neuroticism is associated with decline, and greater Conscientiousness is associated with improvement in performance on measures of general cognitive function and memory in adults. Further studies are needed to determine the extent to which personality traits in midlife are associated with clinically significant cognitive outcomes in older adults, such as mild cognitive impairment and dementia, and to identify potential mediators of the association between personality and cognitive trajectories.

    The North-East Corridor project aims to use a top-down inversion methodology to quantify sources of Greenhouse Gas (GHG) emissions over urban domains such as Washington DC / Baltimore with high spatial and temporal resolution. Atmospheric transport of tracer gases from an emission source to a tower mounted receptor are usually conducted using the Weather Research and Forecasting (WRF) model. For such simulations, WRF employs a parameterized turbulence model and does not resolve the fine scale dynamics generated by the flow around buildings and communities comprising a large city. The NIST Fire Dynamics Simulator (FDS) is a computational fluid dynamics model that utilizes large eddy simulation methods to model flow around buildings at length scales much smaller than is practical with WRF. FDS has the potential to evaluate the impact of complex urban topography on near-field dispersion and mixing difficult to simulate with a mesoscale atmospheric model. Such capabilities may be important in determining urban GHG emissions using atmospheric measurements. A methodology has been developed to run FDS as a sub-grid scale model within a WRF simulation. The coupling is based on nudging the FDS flow field towards that computed by WRF, and is currently limited to one way coupling performed in an off-line mode. Using the coupled WRF / FDS model, NIST will investigate the effects of the urban canopy at horizontal resolutions of 10-20 m in a domain of 12 x 12 km. The coupled WRF-FDS simulations will be used to calculate the dispersion of tracer gases in the North-East Corridor and to evaluate the upwind areas that contribute to tower observations, referred to in the inversion community as influence functions. Results of this study will provide guidance regarding the importance of explicit simulations of urban atmospheric turbulence in obtaining accurate estimates of greenhouse gas emissions and transport.

    Black churches are an important community resource and a potentially powerful actor in adolescent health promotion. However, limited research exists describing the factors that may influence the successful implementation of evidence-based adolescent sexual health programs in churches. In the present study, a multi-informant approach was used to identify facilitators and barriers to implementing adolescent sexual health programs in black churches. Nine Black churches located in Baltimore, MD, were recruited to participate in this study. The senior pastor and youth minster from each congregation participated in an in-depth interview (N = 18). A total of 45 youth (ages 13-19 years) and 38 parents participated in 15 focus groups. Qualitative data were transcribed verbatim and analyzed using a qualitative content analytic approach. Participants agreed that comprehensive adolescent sexual health education should be available for youth in black churches. They also believed that abstaining from sex should be discussed in all adolescent sexual health programs. Three facilitators were discussed: widespread endorsement of church-based adolescent sexual health education, positive influence of youth ministers on youth, and life lessons as teaching tools. Four barriers are described: perceived resistance from congregants, discomfort among youth, lack of financial resources, and competing messages at home about sexual health. Our findings suggest that churches are a preferred place for adolescent sexual health education among some parents and youth. Study findings also reinforce the feasibility and desirably of church-based adolescent sexual health programs. Copyright © 2016 Society for Adolescent Health and Medicine. Published by Elsevier Inc.

    1999-01-01

    The heavily urbanized and industrialized Baltimore Harbor/Patapsco River/Back River system is one of the most highly contaminated regions of the Chesapeake Bay. In June 1996, surficial sediments were collected at 80 sites throughout the subestuarine system, including historically undersampled creek sand embayments. The samples were analyzed for a suite of hydrophobic organic contaminants (HOCs) consisting of 32 polycyclic aromatic hydrocarbons (PAHs) and 113 polychlorinated biphenyl (PCB) congeners. Total PAH and total PCB concentrations ranged from 90 to 46,200 and 8 to 2,150 ng/g dry weight, respectively. There was enormous spatial variability in the concentrations of HOCs, which was not well correlated to grain size or organic carbon content, suggesting nonequilibrium partitioning and/or proximity to sources as important factors explaining the observed spatial variability. High concentrations of both classes of HOCs were localized around major urban stormwater runoff discharges. Elevated PAH concentrations were also centered around the Sparrow's Point Industrial Complex, most likely a result of the pyrolysis of coal during the production of steel. All but 1 of the 80 sites exceeded the effects range-low (ERL) for total PCBs and, of those sites, 40% exceeded the effects range-medium (ERM), suggesting toxicity to marine benthic organisms would frequently occur. Using principal component analysis, differences in PAH signatures were discerned. Higher molecular weight PAHs were enriched in signatures from sediments close to suspected sources (i.e., urban stormwater runoff and steel production complexes) compared to those patterns observed at sites further from outfalls or runoff. Due to varying solubilities and affinities for organic matter of the individual PAHs, partitioning of the heavier weight PAHs may enrich settling particles with high molecular weight PAHs. Lower molecular weight PAHs, having lower affinity for particles, may travel from the source to a

    Neighborhood characteristics have been proposed to influence birth outcomes through psychosocial and behavioral pathways, yet empirical evidence is lacking. Using data from an urban, low-income sample, this study examined the impact of the neighborhood environment on birthweight and evaluated mediation by psychosocial and behavioral factors. The sample included 726 women who delivered a live birth at Johns Hopkins Hospital in Baltimore, Maryland, USA between 1995 and 1996. Census-tract data were used to create a principal component index of neighborhood risk based on racial and economic stratification (% Black, % poverty), social disorder (violent crime rate), and physical deterioration (% boarded-up housing) (alpha=0.82). Information on sociodemographic, psychosocial, and behavioral factors was gathered from a postpartum interview and medical records. Random intercept multilevel models were used to estimate neighborhood effects and assess potential mediation. Controlling for sociodemographic characteristics, a standard deviation increase in neighborhood risk conferred a 76g birthweight decrement. This represents an approximate 300g difference between the best and worst neighborhoods. Although stress (daily hassles), perceived locus-of-control, and social support were related to birthweight, their adjustment reduced the neighborhood coefficient by only 12%. In contrast, the neighborhood effect was reduced by an additional 30% and was no longer statistically significant after adjustment for the behavioral factors of smoking, drug use, and delayed prenatal care. These findings suggest that neighborhood factors may influence birthweight by shaping maternal behavioral risks. Thus, neighborhood level interventions should be considered to address multiple maternal and infant health risks. Future studies should examine more direct measures of neighborhood stress, such as perceived neighborhood disorder, and evaluate alternative mechanisms by which neighborhood factors

    Experience Corps (EC) represents a high-intensity, intergenerational civic engagement activity where older adults serve as mentors and tutors in elementary schools. Although high-intensity volunteer opportunities are designed to enhance the health and well being of older adult volunteers, little is known about the negative and positive aspects of volunteering unique to intergenerational programs from the volunteer's perspective. Stressors and rewards associated with volunteering in EC were explored in 8 focus group discussions with 46 volunteers from EC Baltimore. Transcripts were coded for frequently expressed themes. Participants reported stressors and rewards within 5 key domains: intergenerational (children's problem behavior, working with and helping children, observing/facilitating improvement or transformation in a child, and developing a special connection with a child); external to EC (poor parenting and children's social stressors); interpersonal (challenges in working with teachers and bonding/making social connections); personal (enjoyment, self-enhancement/achievement, and being/feeling more active); and structural (satisfaction with the structural elements of the EC program). Volunteers experienced unique intergenerational stressors related to children's problem behavior and societal factors external to the EC program. Overall, intergenerational, interpersonal, and personal rewards from volunteering, as well as program structure may have balanced the stress associated with volunteering. A better understanding of stressors and rewards from high-intensity volunteer programs may enhance our understanding of how intergenerational civic engagement volunteering affects well being in later life and may inform project modifications to maximize such benefits for future volunteers and those they serve. © The Author 2014.

    Estuarine sediments in regions with prolonged histories of industrial activity are often laden to significant depths with complex contaminant mixtures, including trace metals and persistent organic pollutants. Given the complexity of assessing risks from multi-contaminant exposures, the direct measurement of impacts to biological receptors is central to characterizing contaminated sediment sites. Though biological consequences are less commonly assessed at depth, laboratory-based toxicity testing of subsurface sediments can be used to delineate the scope of contamination at impacted sites. The extent and depth of sediment toxicity in Bear Creek, near Baltimore, Maryland, USA, was delineated using 10-day acute toxicity tests with the estuarine amphipod Leptocheirus plumulosus, and chemical analysis of trace metals and persistent organic pollutants. A gradient of toxicity was demonstrated in surface sediments with 21 of 22 tested sites differing significantly from controls. Effects were most pronounced (100% lethality) at sites proximate to a historic industrial complex. Sediments from eight of nine core samples to depths of 80 cm were particularly impacted (i.e., caused significant lethality to L. plumulosus) even in locations overlain with relatively non-toxic surface sediments, supporting a conclusion that toxicity observed at the surface (top 2 cm) does not adequately predict toxicity at depth. In seven of nine sites, toxicity of surface sediments differed from toxicity at levels beneath by 28 to 69%, in five instances underestimating toxicity (28 to 69%), and in two instances overestimating toxicity (44 to 56%). Multiple contaminants exceeded sediment quality guidelines and correlated positively with toxic responses within surface sediments (e.g., chromium, nickel, polycyclic aromatic hydrocarbon (PAH), total petroleum hydrocarbon). Use of an antibody-based PAH biosensor revealed that porewater PAH concentrations also increased with depth at most sites. This

    Social, ecological, and climatic factors interact creating a heterogeneous matrix that determines the spatiotemporal distribution of mosquitoes and human risks of exposure to the diseases they transmit. We explore linkages between the social and institutional processes behind residential abandonment, urban ecology, and the interactions of socio-ecological processes with abiotic drivers of mosquito production. Specifically, we test the relative roles of infrastructure degradation and vegetation for explaining the presence of Aedes albopictus Skuse 1894 to better predict spatial heterogeneity in mosquito exposure risk within urban environments. We further examine how precipitation interacts with these socially underpinned biophysical variables. We use a hierarchical statistical modeling approach to assess how environmental and climatic conditions over 3 years influence mosquito ecology across a socioeconomic gradient in Baltimore, MD. We show that decaying infrastructure and vegetation are important determinants of Ae. albopictus infestation. We demonstrate that both precipitation and vegetation influence mosquito production in ways that are mediated by the level of infrastructural decay on a given block. Mosquitoes were more common on blocks with greater abandonment, but when precipitation was low, mosquitoes were more likely to be found in higher-income neighborhoods with managed container habitat. Likewise, although increased vegetation was a negative predictor of mosquito infestation, more vegetation on blocks with high abandonment was associated with the largest mosquito populations. These findings indicate that fine spatial scale modeling of mosquito habitat within urban areas is needed to more accurately target vector control. © The Authors 2017.

    2017-10-01

    Despite evidence for the efficacy of buprenorphine treatment in primary care, few studies have identified factors associated with treatment success, nor have such factors been evaluated in community settings. Identifying correlates of treatment success can facilitate the development of treatment models tailored for distinct populations, including low-income communities of color. The current study examined client-level socio-demographic factors associated with treatment success in community-based buprenorphine programs serving vulnerable populations. Data were abstracted from client records for participants (N=445) who met DSM-IV criteria for opioid dependence and sought treatment at one of Behavioral Health Leadership Institute's two community-based recovery programs in Baltimore City from 2010 to 2015. Logistic regression estimated the odds ratios of treatment success (defined as retention in treatment for ≥90days) by sociodemographic predictors including age, race, gender, housing, legal issues and incarceration. The odds of being retained in treatment ≥90days increased with age (5% increase with each year of age; pfactors. Clients who reported unstable housing had a 41% decreased odds of remaining in treatment for 90 or more days compared to clients who lived independently at intake. Treatment success did not significantly differ by several other client-level characteristics including gender, race, employment, legal issues and incarceration. In vulnerable populations, the age factor appears sufficiently significant to justify creating models formulated for younger populations. The data also support attention to housing needs for people in treatment. Findings from this paper can inform future research and program development. Copyright © 2017 Elsevier Ltd.

    The stress responses of the hypothalamic-pituitary-adrenal axis can produce adverse effects on the brain. Previous studies have concluded that an elevated level of cortisol is a risk factor for cognitive dysfunction and decline in aging but have been limited by sex exclusion, restricted cognitive batteries, and small sample sizes. To examine associations among salivary cortisol metrics and cognitive domain scores in an urban adult population. A cross-sectional analysis was conducted using data from a longitudinal study involving 1140 Baltimore, Maryland, residents aged 50 to 70 years. Four salivary cortisol samples were obtained from 967 participants across 1 study visit (before, during, and after cognitive testing as well as at the end of the visit) from which 7 cortisol metrics were created. We examined associations of cortisol metrics with cognitive performance using multiple linear regression. Performance on 20 standard cognitive tests was measured and combined to form summary measures in 7 domains (language, processing speed, eye-hand coordination, executive functioning, verbal memory and learning, visual memory, and visuoconstruction). Higher levels of pretest and mean cortisol as well as the area under the curve of cortisol over the study visit were associated with worse performance (P executive functioning, verbal memory and learning, and visual memory). For instance, an interquartile range increase in the area under the curve was equivalent to a decrease in the language score expected from an increase in 5.6 (95% confidence interval, 4.2-7.1) years of age. Elevated cortisol was associated with poorer cognitive function across a range of domains in this large population-based study. We believe the findings are consistent with the hypothesis that hypothalamic-pituitary-adrenal axis dysregulation may be a risk factor for poorer cognitive performance in older persons.

    This abbreviated data report presents results of ground water, surface water, and stream sediment reconnaissance in the National Topographic Map Series (NTMS) Baltimore 1 0 x 2 0 NTMS quadrangle. Surface sediment samples were collected at 993 sites. Ground water samples were collected at 777 sites. Neutron activation analysis (NAA) results are given for uranium and 16 other elements in sediments, for uranium and 8 other elements in ground water, and for uranium and 9 other elements in surface water. Field measurements and observations are reported for each site. Analytical data and field measurements are presented. Data from ground water sites include: (1) water chemistry measurements (pH, conductivity, and alkalinity), (2) physical measurements, where applicable (water temperature, well description, etc.), and (3) elemental analyses (U, Al, Br, Cl, Dy, F, Mn, Na, and V). Data from sediment sites include: (1) stream water chemistry measurements (pH, conductivity and alkalinity), and (2) elemental analyses for sediment samples (U, Th, Hf, Al, Ce, Dy, Eu, Fe, La, Lu, Mn, Sc, Sm, Na, Ti, V, and Yb). Sample site descriptors (stream characteristics, vegetation, etc.) are also tabulated. Areal distribution maps, histograms, and cumulative frequency plots for most elements and for U/Th and U/Hf ratios are included on the microfiche. Key data from stream water sites include: (1) water quality measurements (pH, conductivity and alkalinity) and (2) elemental analyses (U, Al, Br, Cl, Dy, F, Mg, Mn, Na, and V). Uranium concentrations in the sediments that were above detection limits ranged from up to 38.7 ppM. The samples with high uranium values also have high thorium values, suggesting that most of the uranium is held within resistate minerals. The north-northeast trend of the geologic units is clearly reflected in the data

    Space Station Freedom operations management concepts must be responsive to the unique challenges presented by the permanently manned international laboratory. Space Station Freedom will be assembled over a three year period where the operational environment will change as significant capability plateaus are reached. First Element Launch, Man-Tended Capability, and Permanent Manned Capability, represent milestones in operational capability that is increasing toward mature operations capability. Operations management concepts are being developed to accomodate the varying operational capabilities during assembly, as well as the mature operational environment. This paper describes operations management concepts designed to accomodate the uniqueness of Space Station Freedoom, utilizing tools and processes that seek to control operations costs.

    The export markets for tropical fruit from Thailand are presently limited to Hong Kong, Singapore, Malaysia, Europe and the Middle East where plant quarantine regulations are not as rigorous as they are in other parts of the world. Attempts are being made to open up new market in Japan, Australia and the United States of America. However, in order to gain access to these markets the produce must be completely free of restricted quarantine pests such as oriental fruit fly (Dacus dorsalis) and melon fruit fly (D. Cucurbitae). Many importing countries to restrict use of chemicals in agricultural produce by fumigation, the use of irradiation technology for pest problems appears to be an acceptable alternative

    Researches using gamma radiation for disinfestation of Oriental fruit fly in 'Carabao' ('Manila Super') mangoes were undertaken using the Probit 9 or 99.9968% mortality test. The results showed that the mature larvae of the fruit fly are the most tolerant stage of this insect to irradiation with the eggs as the most sensitive. On treating more than 100,000 mature larvae in mangoes, a minimum dose of 100 Gy was found to prevent emergence of adult fruit flies and maintain quarantine security or a complete elimination of the possibility of introducing this pest into the importing country. Therefore, the use of 100-Gy irradiation as a quarantine treatment against Oriental fruit fly in the mature green Philippine 'carabao' mango fruits is recommended

    The Shippingport Atomic Power Station was located on the Ohio River in Shippingport Borough (Beaver County), Pennsylvania, USA. The US Atomic Energy Commission (AEC) constructed the plant in the mid-1950s on a seven and half acre parcel of land leased from Duquesne Light Company (DLC). The purposes were to demonstrate and to develop Pressurized Water Recovery technology and to generate electricity. DLC operated the Shippingport plant under supervision of (the successor to AEC) the Department of Energy (DOE)-Naval Reactors (NR) until operations were terminated on October 1, 1982. NR concluded end-of-life testing and defueling in 1984 and transferred the Station's responsibility to DOE Richland Operations Office (RL), Surplus Facility Management Program Office (SFMPO5) on September 5, 1984. SFMPO subsequently established the Shippingport Station Decommissioning Project and selected General Electric (GE) as the Decommissioning Operations Contractor.

    In the present work, survival of the Mediterranean fruit fly Ceratitis capitata (Wiedemann) (Diptera: Tephritidae) on artificially infested 'Clemenules' clementine mandarins (Citrus reticulata Blanco) was assessed on fruit subjected to integrated quarantine treatments consisting of irradiation with X-rays at doses of 0 (control), 30, 54, and 164 Gy followed by exposure to 1 deg C for 0 (control), 3, 6, 9, or 12 days. Additionally, physico-chemical (rind color, firmness, and physiological disorders, soluble solids concentration, titratable acidity, maturity index, juice yield, and ethanol and acetaldehyde content) and sensory (sweetness, acidity, sensory maturity index, off-flavors, and mandarin-like flavor) fruit quality of 'Clemenules' clementines were assessed on X-irradiated fruit exposed to 1 deg C for 0 (control), 6, or 12 days. Complete insect mortality with no negative effects on fruit quality after 7 days at 20 deg C of shelf life was obtained on clementines firstly X-irradiated at 30 Gy and subsequently exposed to 1 deg C for 2 days. This combination of treatments considerably reduced quarantine time if compared to standard cold quarantine treatments (1.1-2.2 deg C for 14-18 days) and therefore showed promise as a potential commercial treatment for Spanish citrus exports [es

    Aware of the increasing impact of human activities on the Earth system, Belgian Science Policy Office (Belspo) launched in 1997 a research programme in support of a sustainable development policy. This umbrella programme included the Belgian Scientific Programme on Antarctic Research. The International Polar Foundation, an organization led by the civil engineer and explorer Alain Hubert, was commissioned by the Belgian Federal government in 2004 to design, construct and operate a new Belgian Antarctic Research Station as an element under this umbrella programme. The station was to be designed as a central location for investigating the characteristic sequence of Antarctic geographical regions (polynia, coast, ice shelf, ice sheet, marginal mountain area and dry valleys, inland plateau) within a radius of 200 kilometers (approx.124 miles) of a selected site. The station was also to be designed as "state of the art" with respect to sustainable development, energy consumption, and waste disposal, with a minimum lifetime of 25 years. The goal of the project was to build a station and enable science. So first we needed some basic requirements, which I have listed here; plus we had to finance the station ourselves. Our most important requirement was that we decided to make it a zero emissions station. This was both a philosophical choice as we thought it more consistent with Antarctic Treaty obligations and it was also a logistical advantage. If you are using renewable energy sources, you do not have to bring in all the fuel.

    Brazil is one of the largest mango producers and the third largest mango exporter worldwide. Irradiation treatment and its commercial feasibility have been studied in our country to make it possible to develop new markets and, consequently, to compete with the major exporters of mangoes, Mexico and India. This work was designed to compare irradiation treatment with the hot water dip treatment in mangoes cv. Tommy Atkins for export and to verify that the main attributes for acceptance, color and texture, as well as carbohydrate and organic acid contents, were maintained. In this study, the fruit was divided into groups: control, hot water dip-treated (46 °C for 90 min), and irradiation-treated at doses of 0.4 kGy and 1.0 kGy. The fruit was stored at low temperature (11 °C±2) for 14 days and then at room temperature (23 °C±2) until the end of the study. The results indicated that the fruit given a dose of 1.0 kGy remained in a less advanced stage of ripening (stage 3) throughout the storage period, but experienced a greater loss of texture in the beginning of the experiment. It was noted that only the control group had higher levels of citric acid and succinic acid on the last day of the experiment. There were no significant differences in the total sugar content between any treatment groups. Gamma radiation can be used as a quarantine treatment and does not interfere negatively with the quality attributes of mangoes. - Highlights: ► In Brazil, one of the largest producers and exporters of mangoes, tropical fruits are routinely treated with a hot water dip. ► Results from this study demonstrate that irradiation is a good alternative to this conventional quarantine treatment. ► Carbohydrate and organic acid results are presented for irradiation and hot water dip treatments. ► Texture measurements are shown as a function of storage time for each of these treatments.

    Baltimore, Philadelphia, and Washington, DC are geographically proximate cities with high HIV prevalence, including among black men who have sex with men (BMSM). Using data collected among BMSM in CDC's National HIV Behavioral Surveillance project, we compared socio-demographic characteristics, HIV risk behaviors, and service utilization to explore similarities and differences that could inform local and regional HIV intervention approaches. BMSM were recruited through venue time location sampling, June-December, 2011. Participants completed identical socio-behavioral surveys and voluntary HIV testing. Analyses were conducted among the full sample and those aged 18-24. Participants included 159 (DC), 364 (Baltimore), and 331 (Philadelphia) eligible BMSM. HIV prevalence was 23.1% (DC), 48.0% (Baltimore), 14.6% (Philadelphia) with 30.6%, 69.0%, 33.3% unrecognized HIV infection, respectively. Among BMSM 18-24, HIV prevalence was 11.1% (DC), 38.9% (Baltimore), 9.6% (Philadelphia) with unrecognized HIV infection 0.0%, 73.8%, 60.0% respectively. Compared with the other 2 cities, Baltimore participants were less likely to identify as gay/homosexual; more likely to report unemployment, incarceration, homelessness, sex exchange; and least likely to use the internet for partners. DC participants were more likely to have a college degree and employment. Philadelphia participants were more likely to report gay/homosexual identity, receptive condomless anal sex, having only main partners, and bars/clubs as partner meeting places. Sexually transmitted disease testing was universally low. Analyses showed especially high HIV prevalence among BMSM in Baltimore including among young BMSM. Socio-demographic characteristics and HIV infection correlates differed across cities but unrecognized HIV infection and unknown partner status were universally high.

    Green gram (Vigna radiata (L.) Wilkzec) an important legume crop in India is grown in 33.4 lakh hectares. India accounts for ∼ 60% of the world's green gram area but contributes only 47% of its production. Major constraint in storage is the pulse beetle Callosobruchus maculatus Fab. (Coleoptera: Bruchidae), which may cause damage upto 100%. It is widespread throughout tropics and sub-tropics with wide host range and also has different strains. Fumigation with methyl bromide (MB) has been the most widely applied management practice for its control. However, the ozone depleting effect of MB has led to restrictions in its use. Therefore, there is a need for an alternative strategy for controlling the pests. Irradiation, an approved technology by International Plant Protection Convention, seems to be a viable non-chemical, residue-free strategy. Therefore, present studies were conducted to see the efficacy of electron beam (EB) irradiation as quarantine disinfestation treatment against green gram seeds infested with different stages of the target pest, C. maculatus

    In Brazil the tomato-fruit-borer is responsible up to 45% for the loss of the production. The objective of the present report is evaluate the effects of gamma radiation ( 60 Co) on life cycle (eggs and larvae) of Neoleucinodes elegantalis in tomato fruits. The insects were irradiated at doses of 0 (control), 50, 100, 150, 200, 250, 300 and 400 Gy, in a Gammacell 220 source at dose rate of 1.4 kGy/h. Each treatment consists of four repetitions containing 10 insects, totaling 50 insects. After irradiation, the insects were maintained under controlled conditions of 25±3 deg C and relative humidity from 65 to 75%. The evaluations were done daily, counted the number of died insects, eggs and emerged larvae. With the obtained results, we could determine the lethal and sterilizing doses for all phases of cycle life in N. elegantalis for a possible quarantine treatment to export tomato fruits. These results permit conclude that the dose capable to avoid further development of stage of eggs and larvae were doses of 100 and 200 Gy. (author)

    Molecular diagnostic assays offer both exquisite sensitivity and the ability to test a wide variety of sample types. Various types of environmental sample, such as detritus and concentrated water, might provide a useful adjunct to sentinels in routine zebrafish health monitoring. Similarly, antemortem sampling would be advantageous for expediting zebrafish quarantine, without euthanasia of valuable fish. We evaluated the detection of Mycobacterium chelonae, M. fortuitum, M. peregrinum, Pseudocapillaria tomentosa, and Pseudoloma neurophilia in zebrafish, detritus, pooled feces, and filter membranes after filtration of 1000-, 500-, and 150-mL water samples by real-time PCR analysis. Sensitivity varied according to sample type and pathogen, and environmental sampling was significantly more sensitive than zebrafish sampling for detecting Mycobacterium spp. but not for Pseudocapillaria neurophilia or Pseudoloma tomentosa. The results of these experiments provide strong evidence of the utility of multiple sample types for detecting pathogens according to each pathogen's life cycle and ecological niche within zebrafish systems. In a separate experiment, zebrafish subclinically infected with M. chelonae, M. marinum, Pleistophora hyphessobryconis, Pseudocapillaria tomentosa, or Pseudoloma neurophilia were pair-spawned and individually tested with subsets of embryos from each clutch that received no rinse, a fluidizing rinse, or were surface-disinfected with sodium hypochlorite. Frequently, one or both parents were subclinically infected with pathogen(s) that were not detected in any embryo subset. Therefore, negative results from embryo samples may not reflect the health status of the parent zebrafish. PMID:28724491

    The western flower thrips, Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae), is an important pest of fresh horticultural produce and as such is considered a biosecurity risk in many countries from which it is absent. Information is needed on the radiation tolerance of important surface pests of quarantine importance such as F. occidentalis so that phytosanitary irradiation treatments for exported fresh commodities can be lowered to below the 400 Gy generic treatment currently approved for most insects in the United States and Australia. Lowering the dose will help minimize any product quality problems, reduce costs, and shorten treatment time. In large-scale confirmatory trials conducted in two independent laboratories in Hawaii and Australia, a dose of 250 Gy (measured doses 222-279 Gy) applied to adult F. occidentalis on green beans resulted in no reproduction in 5,050 treated individuals. At 250 Gy, the effective dose is significantly below the 400 Gy generic dose, demonstrating that irradiation at this lowered level is an effective method for the disinfestation of F. occidentalis from fresh horticultural produce.

    For the purpose of developing new quarantine procedure alternative to fumigation, electron beam irradiation was examined in the disinfestation of arthroped pests that infest cut flowers. Immature and adult two-spotted spider mites, Tetranychus urticae, which is a typical pest in horticulture due to high fertility, parthenogenesis and chemical resistance, were irradiated at a Van de graaf electron accelerator (2.5 MeV) at 0.2 - 1.4 kGy. They decreased radiosensitivity with aging. Female was much more tolerant than male throughout their life. Irradiation controlled the fertility of both sexes, and also feeding and behavioral activities. Cut flowers irradiated with the Dynamitron accelerator (5 MeV) showed various responses according to species, cultivars and tissues of plants. Carnations, tulips and gladioluses were tolerant in disinfesting or sterilizing, but some cultivars of chrysanthemum and rose showed the symptom of injury, in which flowering was delayed at low dose, and the failure of flowering and the chlorosis of leaves occurred at high dose. Floral organs were much more sensitive to radiation than others. Sensitive plants also showed the reduced production of ethylene. (K.I.)

    The objective of this work has been to determine the lethal dose of gamma radiation of Cobalt-60 for the Stenoma catenifer eggs. For the irradiation of the eggs an irradiador Gammacell-220 (CO60) was utilized, (Rate dose: 1.054 kGY/h). The doses were: 0, 25, 50, 75, 100, 125 and 150 Gy, 90 eggs/dose (six repetitions). The number of caterpillars emerged was evaluated, and the survivors growed in seeds of avocado. The adults obtained were coupled with normal insects, growed in boxes with double face paper containing the food (10% honey) and a fruit of avocado. The experimental design was totally random, being the data submitted to the analysis of the varianza and the averages compared by the test of Tukey (P=5%). The emergence of caterpillars from the treated eggs with dose of 0, 25 and 50 Gy was verified. The dose of 50 Gy caused deformation in the caterpillars emerged. The effect of the gamma radiation in the viability of the eggs was proportional to the dose increase. The adults from the eggs dealt with 25 Gy presented non viabilty of 92,85 and 100% for male and female, respectively. A radiation gamma of 75 Gy is recommended for treatment quarantine for avocado fruits infested with of S. catenifer eggs

    Medicine and religion worked in close synchronisation during the leprosy outbreak of New Caledonia (1890-1950). Once isolation of leprosy-affected people became mandatory doctors and missionaries came together to promote a particular form of medical practice that tied charitable zeal with cutting-edge medical research, developing a sophisticated set of medical practices that catered for the soul as well as the body. Such practices went hand-in-hand with ideas developed by doctors in the earlier stages of the epidemic about the way in which the disease had entered the Kanak (local Melanesian) population. Doctors and missionaries admitted that immoral colonial channels had upset the delicate balance of local social and biological rhythms. Yet they also believed that the highly contagious nature of the outbreak was linked to the inferior state of Kanak. This paper aims to highlight the way in which the leprosaria system in New Caledonia represented a double-edged moral high-ground within the French medical colonial narrative. It tracks the complex way in which emotionally charged arguments about contagion, science and spirituality constructed an ideology of humanitarian quarantine which was used to justify a highly aggressive form of medical biocontrol.

    The weakness of small island electrical grids implies a handicap for the electrical generation with renewable energy sources. With the intention of maximizing the installation of photovoltaic generators in the Canary Islands, arises the need to develop a solar forecasting system that allows knowing in advance the amount of PV generated electricity that will be going into the grid, from the installed PV power plants installed in the island. The forecasting tools need to get feedback from real weather data in "real time" from remote weather stations. Nevertheless, the transference of this data to the calculation computer servers is very complicated with the old point to point telecommunication systems that, neither allow the transfer of data from several remote weather stations simultaneously nor high frequency of sampling of weather parameters due to slowness of the connection. This one project has developed a telecommunications infrastructure that allows sensorizadas remote stations, to send data of its sensors, once every minute and simultaneously, to the calculation server running the solar forecasting numerical models. For it, the Canary Islands Institute of Technology has added a sophisticated communications network to its 30 weather stations measuring irradiation at strategic sites, areas with high penetration of photovoltaic generation or that have potential to host in the future photovoltaic power plants connected to the grid. In each one of the stations, irradiance and temperature measurement instruments have been installed, over inclined silicon cell, global radiation on horizontal surface and room temperature. Mobile telephone devices have been installed and programmed in each one of the weather stations, which allow the transfer of their data taking advantage of the UMTS service offered by the local telephone operator. Every minute the computer server running the numerical weather forecasting models receives data inputs from 120 instruments distributed

    Young adults are generally overlooked in tobacco control initiatives, even though they are critical to sustained success. African American young adults who are not in higher education or working are particularly vulnerable to harmful tobacco use, given high smoking rates and limited access to cessation services. Guided by community-based participatory research (CBPR) principles, we sought to identify program and community-level strategies to reduce tobacco use among African American young adults in Baltimore. We describe the challenges and opportunities for integrating effective tobacco control into community-based education and job training programs for unemployed young adults. As part of a longstanding community-research partnership in Baltimore, we conducted fourteen semistructured key informant interviews with leaders from city government and education and job training programs for young adults. The research design, data collection, analysis, and dissemination all included dialogue between and active contribution by both research and community partners. Interview data were structured into opportunities (mindset for change and desire for bonds with a trusted adult), challenges (culture of fatalism, tobacco as a stress reliever, and culture of tobacco use among young adults), and possible tobacco control solutions (tobacco education designed with and for program staff and participants and integration of tobacco issues into holistic program goals and policies). The emergent themes enhance our understanding of how tobacco is situated in the lives of unemployed young adults and the potential for building sustainable, community-based public health solutions.

    Urban regions are often impacted more by heat than adjacent rural areas, which is a phenomenon known as the urban heat island (UHI) effect. Urban areas are also highly heterogeneous and notoriously difficult to monitor using standard meteorological protocols—the hottest microclimates within a city often occur in locations that lack open, representative installation sites that are an adequate distance from buildings and direct heat sources. To investigate the challenges of monitoring urban heat, this study examines the sensitivity of temperature and humidity sensors currently used in a Baltimore UHI monitoring network to differences in sun exposure, material on which the data collecting instrument is attached, and land cover class of the vicinity. Sensitivity to sun exposure and attachment site can be interpreted as sources of uncertainty for urban heat monitoring, while sensitivity to land cover may reflect a true source of local temperature and humidity variability. In this study, we present results from a test deployment designed to assess the sensitivity of heat measurements to each of these three factors. We then apply these results to interpret measurements taken across the entire Baltimore UHI monitoring network. These results can then be used to improve heat measurements and more accurately represent and quantify the UHI effect on a broader scale, such as in neighborhoods or urban centers.

    Hydrogen fueling stations are an essential element in the practical application of hydrogen as a vehicle fuel, and a number of issues such as safety, efficiency, design, and operating procedures can only be accurately addressed by a practical demonstration. Regardless of whether the vehicle is powered by an internal combustion engine or fuel cell, or whether the vehicle has a liquid or gaseous fuel tank, the fueling station is a critical technology which is the link between the local storage facility and the vehicle. Because most merchant hydrogen delivered in the US today (and in the near future) is in liquid form due to the overall economics of production and delivery, we believe a practical refueling station should be designed to receive liquid. Systems studies confirm this assumption for stations fueling up to about 300 vehicles. Our fueling station, aimed at refueling fleet vehicles, will receive hydrogen as a liquid and dispense it as either liquid, high pressure gas, or low pressure gas. Thus, it can refuel any of the three types of tanks proposed for hydrogen-powered vehicles -- liquid, gaseous, or hydride. The paper discusses the fueling station design. Results of a numerical model of liquid hydrogen vehicle tank filling, with emphasis on no vent filling, are presented to illustrate the usefulness of the model as a design tool. Results of our vehicle performance model illustrate our thesis that it is too early to judge what the preferred method of on-board vehicle fuel storage will be in practice -- thus our decision to accommodate all three methods.

    Power stations are characterized by a wide variety of mechanical and electrical plant operating with structures, liquids and gases working at high pressures and temperatures and with large mass flows. The voltages and currents are also the highest that occur in most industries. In order to achieve maximum economy, the plant is operated with relatively small margins from conditions that can cause rapid plant damage, safety implications, and very high financial penalties. In common with other process industries, power stations depend heavily on control and instrumentation. These systems have become particularly significant, in the cost-conscious privatized environment, for providing the means to implement the automation implicit in maintaining safety standards, improving generation efficiency and reducing operating manpower costs. This book is for professional instrumentation engineers who need to known about their use in power stations and power station engineers requiring information about the principles and choice of instrumentation available. There are 8 chapters; chapter 4 on instrumentation for nuclear steam supply systems is indexed separately. (Author)

    Studies on helminthfauna of marsh deer Blastocerus dichotomus Illiger, 1815 are rare, although helminthic diseases are an important cause of mortality in these animals. Fifteen male and female adult marsh deer from Sergio Motta's hydroelectric power station flooding area at Paraná River which died during the capture and quarantine procedures, between 1998 and 1999, were necropsied. Three trematodes species, Paramphistomum cervi, Balanorchis anastrofus and Zygocotyle lunatum, all belonging to superfamily Paramphistomoidea, were identified. The obtained trematodes were identified, counted and their respectives descriptors of infection were determined. All necropsied animals were infected by helminths. Paramphistomum cervi was the most prevalent species, while Zygocotyle lunatum was found in only one animal.

    The loss of stored grain caused by insects generates a problem of economic order of importance, due to concern about the increased supply of food for the world population is expanding. Associated with this fact, there is the problem of nutritional deficiency due to lack of protein, especially for the less privileged populations. The use of ionizing radiation in grains and products stored without a doubt can solve the problem of the losses in these products, since it does not induce resistance to insects and leaves no toxic residue in the products, and is considered an effective and safe method. The aim of the experiment was to determine the effect of ionizing radiation from cobalt-60 as a quarantine treatment for the different stages of development of Callosobruchus maculatus (Fabr., 1972) (Coleóptera, Chysomilidae) in bean Vigna sinensis. The experiment was conducted in the laboratory of Radiobiology and Environment CENA/USP, Piracicaba, SP, Brazil. Bean samples infested with eggs, larvae, pre-pupae and pupae C. maculatus, the experiment consisted of 4 replicates for each stage of the insect's life cycle, and each repetition consisted of 20 individuals (eggs, larvae, pre-pupae and pupae), a total of 200 subjects per treatment which were irradiated with doses of 0 (control), 25, 50, 75 and 100 Gy, a source of cobalt-60, Gammabeam-650 type, in a rate dose of 1.3 kGy / h. The experiment was conducted in a room with a relative of 25 ± 2 ° C temperature and humidity of 70 ± 5%. After 35 days of irradiation process were carried out evaluations of the number of insects emerged in each repetition within the treatments. From the results obtained it was concluded that the dose lethal to eggs and larvae was 25 Gy, while for pre-pupae was 50 Gy, to pupae 100 Gy was not sufficient to control the adult emergence.

    Pests like beetles, moths, fungus and mites normally attack stored products such as grains, spices, flours, brans and tobacco in bale. Among these pests the Sitophilus zeamais is one of the most important pests due its elevated potential of reproduction, infesting a great number of products, inducing great damages. This work had as objective to determine the efficacy of gamma radiation from Cobalt-60 as quarantine treatment for S. zeamais. The insects used in this experiment were reared in maize grains, at the Laboratorio de Artropodes of the Instituto Biologico/SP, on climatic room with 27 ± 2 deg C of temperature and relative humidity of 70 ± 5%. Samples containing 25 adult insects were put in acrylic recipients measuring 2.8cm x 2.8cm. Each treatment had four repetitions, in a total of 100 insects for treatment. They were irradiated with growing doses of gamma radiation: 0 (control); 0,25; 0,5; 0,75; 1,0; 1,25; 1,5; 1,75; 2,0; 2,25 2,5; 2,75; 3,0; 3,5 e 4,0 kGy, in a experimental irradiator of Cobalt-60, model Gammacell-220, located at the Centro de Tecnologia da Radiacoes - CTR of the Instituto de Pesquisas Energeticas e Nucleares - IPEN/CNEN/SP. After irradiation, the samples were transferred to plastic recipients measuring 3,5cm x 10cm, with perforated lids (to allow gaseous exchanges). After the irradiation the samples were kept in climatic room (27 ± 2 deg C and 70 ± 5%). The mortality of insects was evaluated 1 hour after the irradiation and also on the next 7 days. By the results obtained we can conclude that was the dose of 2.75 kGy that induced the immediate mortality for adult insects of the specie S. zeamais. (author)

    Brazil is one of the largest mango producers and the third largest mango exporter worldwide. Irradiation treatment and its commercial feasibility have been studied in our country to make it possible to develop new markets and, consequently, to compete with the major exporters of mangoes, Mexico and India. This work was designed to compare irradiation treatment with the hot water dip treatment in mangoes cv. Tommy Atkins for export and to verify that the main attributes for acceptance, color and texture, as well as carbohydrate and organic acid contents, were maintained. In this study, the fruit was divided into groups: control, hot water dip-treated (46 °C for 90 min), and irradiation-treated at doses of 0.4 kGy and 1.0 kGy. The fruit was stored at low temperature (11 °C±2) for 14 days and then at room temperature (23 °C±2) until the end of the study. The results indicated that the fruit given a dose of 1.0 kGy remained in a less advanced stage of ripening (stage 3) throughout the storage period, but experienced a greater loss of texture in the beginning of the experiment. It was noted that only the control group had higher levels of citric acid and succinic acid on the last day of the experiment. There were no significant differences in the total sugar content between any treatment groups. Gamma radiation can be used as a quarantine treatment and does not interfere negatively with the quality attributes of mangoes.

    Visual inspection is the most commonly used method for detecting quarantine pests in agricultural cargo items at ports. For example, solid wood packing material (SWPM) at ports may be a pathway for wood pests and is a frequent item of inspection at ports. The inspection process includes examination of the external surface of the item and often destructive sampling to detect internal pest targets. There are few tools available to inspectors to increase the efficiency of inspection and reduce the labor involved. Ion mobility spectrometry (IMS) has promise as an aid for inspection. Because pests emit volatile organic compounds (VOCs) such as hormone like substances, Ion Mobility Spectrometry (IMS) was investigated for possible utility for detecting pests during inspection. SWPM is a major pest pathway in trade, and fumigation of many kinds of wood, including SWPM, with methyl bromide (MeBr) following a published schedule1 is regularly conducted for phytosanitary reasons prior to shipment to the United States. However, the question remains as to how long the methyl bromide remains in the wood samples after fumigation such that it could act as an interferent to the detection of pest related VOC emissions. This work investigates the capability of ion mobility spectrometry to detect the presence of residual methyl bromide in fumigated maple and poplar wood samples at different times post fumigation up to 118 days after fumigation. Data show that MeBr can be detected in the less dense poplar wood up to 118 days after fumigation while MeBr can be detected in the denser maple wood 55 days after fumigation.

    Bamboo (genera Bambusa and Phyllstachys) is one of the fastest growing and economically important plants in the world, and it is cultivated widely throughout southern China. China annually exports to the United States significant quantities of bamboo garden stakes (Bambusa spp.). In recent years, Plant Protection and Quarantine officers of the U.S. Department of Agriculture-Animal and Plant Health Inspection Service have made numerous interceptions of the bamboo borer, Chlorophorus annularis Fairmaire (Coleoptera: Cerambycidae), in bamboo products from China. This species is considered to have high pest risk potential in the trade of bamboo products. As a fumigant, sulfuryl fluoride (SF) would be a practical alternative to methyl bromide (MeBr) fumigation. Here, we report the results of SF fumigation tests for C. annularis in bamboo poles at three doses--96 g/m3 at 15.9 degrees C, 80 g/m3 at 21.5 degrees C, and 64 g/m3 at 26.0 degrees C--in glass test chambers. Commercial standard fumigations were also conducted in a standard 6.1-m-long, 33.2-m3 (standard height, 20-feet) marine general cargo container loaded to 80% (vol:vol) with similar bamboo poles, and sufficient levels of SF were obtained during the 24-h fumigations. During the course of these tests, 2424 larvae, 90 pupae, and 23 adults in total were killed, with no survivors. A treatment schedule using SF is proposed for bamboo as an alternative to MeBr at several temperatures tested.

    The loss of stored grain caused by insects generates a problem of economic order of importance, due to concern about the increased supply of food for the world population is expanding. Associated with this fact, there is the problem of nutritional deficiency due to lack of protein, especially for the less privileged populations. The use of ionizing radiation in grains and products stored without a doubt can solve the problem of the losses in these products, since it does not induce resistance to insects and leaves no toxic residue in the products, and is considered an effective and safe method. The aim of the experiment was to determine the effect of ionizing radiation from cobalt-60 as a quarantine treatment for the different stages of development of Callosobruchus maculatus (Fabr., 1972) (Coleóptera, Chysomilidae) in bean Vigna sinensis. The experiment was conducted in the laboratory of Radiobiology and Environment CENA/USP, Piracicaba, SP, Brazil. Bean samples infested with eggs, larvae, pre-pupae and pupae C. maculatus, the experiment consisted of 4 replicates for each stage of the insect's life cycle, and each repetition consisted of 20 individuals (eggs, larvae, pre-pupae and pupae), a total of 200 subjects per treatment which were irradiated with doses of 0 (control), 25, 50, 75 and 100 Gy, a source of cobalt-60, Gammabeam-650 type, in a rate dose of 1.3 kGy / h. The experiment was conducted in a room with a relative of 25 ± 2 ° C temperature and humidity of 70 ± 5%. After 35 days of irradiation process were carried out evaluations of the number of insects emerged in each repetition within the treatments. From the results obtained it was concluded that the dose lethal to eggs and larvae was 25 Gy, while for pre-pupae was 50 Gy, to pupae 100 Gy was not sufficient to control the adult emergence.

    The study is aimed at the optimization of gamma irradiation treatment of sun-dried apricots for quality maintenance and quarantine purposes. Sun-dried apricots pre-treated with potassium meta-bisulphite (KMS) at 2.5% w/v were procured from progressive apricot grower of district Kargil, Ladakh region of Jammu and Kashmir state. The sun-dried apricots were packed in 250 gauge polyethylene packs and gamma irradiated in the dose range 1.0-3.0 kGy. The gamma irradiated fruit including control was stored under ambient (15±2-25±2 o C, RH 70-80%) conditions and periodically evaluated for physico-chemical, sensory and microbial quality parameters. Radiation treatment at dose levels of 2.5 and 3.0 kGy proved significantly (p≤0.05) beneficial in retention of higher levels of β-carotene, ascorbic acid, total sugars and color values without impairing the taste as perceived by the sensory panel analysists. The above optimized doses retained the β-carotene content of sun-dried apricots to the extent of 71.2% and 72.6% compared to 63.9% in control samples after 18 months of storage. Irradiation treatment facilitated the release of residual sulfur dioxide in KMS pre-treated sun-dried apricots significantly (p≤0.05) below the prescribed limit for dried products. During storage, two-fold decrease in sulfur dioxide content was recorded in irradiated samples (3.0 kGy) as compared to 16.9% in control. The above optimized doses besides maintaining the higher overall acceptability of sun-dried apricots resulted in 5 log reductions in microbial load just after irradiation and 1.0 and 1.3 log reductions in yeast and mold and bacterial count after 18 months of ambient storage.

    Hydrogen is an environmentally attractive transportation fuel that has the potential to displace fossil fuels. The Freedom CAR and Freedom FUEL initiatives emphasize the importance of hydrogen as a future transportation fuel. Presently, Las Vegas has one hydrogen fueling station powered by natural gas. However, the use of traditional sources of energy to produce hydrogen does not maximize the benefit. The hydrogen fueling station developed under this grant used electrolysis units and solar energy to produce hydrogen fuel. Water and electricity are furnished to the unit and the output is hydrogen and oxygen. Three vehicles were converted to utilize the hydrogen produced at the station. The vehicles were all equipped with different types of technologies. The vehicles were used in the day-to-day operation of the Las Vegas Valley Water District and monitoring was performed on efficiency, reliability and maintenance requirements. The research and demonstration utilized for the reconfiguration of these vehicles could lead to new technologies in vehicle development that could make hydrogen-fueled vehicles more cost effective, economical, efficient and more widely used. In order to advance the development of a hydrogen future in Southern Nevada, project partners recognized a need to bring various entities involved in hydrogen development and deployment together as a means of sharing knowledge and eliminating duplication of efforts. A road-mapping session was held in Las Vegas in June 2006. The Nevada State Energy Office, representatives from DOE, DOE contractors and LANL, NETL, NREL were present. Leadership from the National hydrogen Association Board of Directors also attended. As a result of this session, a roadmap for hydrogen development was created. This roadmap has the ability to become a tool for use by other road-mapping efforts in the hydrogen community. It could also become a standard template for other states or even countries to approach planning for a hydrogen

    The United States provides an example of a country with (a) legal tobacco/nicotine products (e.g., snus, other smokeless tobacco, cigarettes) differing greatly in risks to health and (b) respected health information websites that continue to omit or provide incorrect differential risk information. Concern for the principles of individual rights, health literacy, and personal autonomy (making decisions for oneself), which are key principles of public health ethics, has been countered by utilitarian arguments for the use of misleading or limited information to protect public health overall. We argue that omitting key health relevant information for current or prospective consumers represents a kind of quarantine of health-relevant information. As with disease quarantines, the coercive effects of quarantining information on differential risks need to be justified, not merely by fears of net negative public health effects, but by convincing evidence that such measures are actually warranted, that public health overall is in imminent danger and that the danger is sufficient to override principles of individual autonomy. Omitting such health-relevant information for consumers of such products effectively blindfolds them and impairs their making informed personal choices. Moral psychological issues that treat all tobacco/nicotine products similarly may also be influencing the reluctance to inform on differential risks. In countries where tobacco/nicotine products are legally sold and also differ greatly in disease risks compared to cigarettes (e.g., smokeless tobacco and vape), science-based, comprehensible, and actionable health information (consistent with health literacy principles) on differential risks should be available and only reconsidered if it is established that this information is causing losses to population health overall.

    Road traffic injuries are a leading killer of youth (aged 15-29) and are projected to be the 7th leading cause of death by 2030. To better understand road traffic crash locations and characteristics in the city of Baltimore, we used police and census data, to describe the epidemiology, hotspots, and modifiable risk factors involved to guide further interventions. Data on all crashes in Baltimore City from 2009 to 2013 were made available from the Maryland Automated Accident Reporting System. Socioeconomic data collected by the US CENSUS 2010 were obtained. A time series analysis was conducted using an ARIMA model. We analyzed the geographical distribution of traffic crashes and hotspots using exploratory spatial data analysis and spatial autocorrelation. Spatial regression was performed to evaluate the impact of socioeconomic indicators on hotspots. In Baltimore City, between 2009 and 2013, there were a total of 100,110 crashes reported, with 1% of crashes considered severe. Of all crashes, 7% involved vulnerable road users and 12% had elderly or youth involvement. Reasons for crashes included: distracted driving (31%), speeding (6%), and alcohol or drug use (5%). After 2010, we observed an increasing trend in all crashes especially from March to June. Distracted driving then youth and elderly drivers were consistently the highest risk factors over time. Multivariate spatial regression model including socioeconomic indicators and controlling for age, gender and population size did not show a distinct predictor of crashes explaining only 20% of the road crash variability, indicating crashes are not geographically explained by socioeconomic indicators alone. In Baltimore City, road traffic crashes occurred predominantly in the high density center of the city, involved distracted driving and extremes of age with an increase in crashes from March to June. There was no association between socioeconomic variables where crashes occurred and hotspots. In depth analysis of

    Litchi (Litchi chinensis) has a very short shelf life of 2-3 days at ambient temperature limiting its marketability. Gamma radiation processing in combination with low temperature storage was explored as a method to achieve shelf life extension and fulfill quarantine requirement for export during storage physics, biochemical, microbiological, organoleptic, antioxidant and radioprotective properties of two major commercially grown Indian cultivars of litchi, 'Shahi' and 'China', were analysed. Radiation treatment reduced microbial load in a dose dependent manner. Radiation (0.5kGy) treated and low temperature stored fruits retained the 'good' organoleptic rating till 28 days of storage while maintaining other quality attributes. (author)

    Social, emotional, and behavioral skills are foundational to learning and long-term success. However, poverty and exposure to adverse childhood experiences reduce the chances of children entering kindergarten socially-behaviorally ready to learn. This study examined the unique impact of 5-year-old children (N = 11,412) entering kindergarten not socially-behaviorally ready on three costly school outcomes by fourth grade in Baltimore City Public Schools: being retained in grade, receiving services and supports through an IEP or 504 plan, and being suspended/expelled. Controlling for all other types of school readiness, students not identified as socially-behaviorally ready for kindergarten were more likely to experience all three school outcomes. Findings underscore the importance of early prevention and intervention strategies targeting parents and social-behavioral readiness skills during the first 5 years of life.

    1997-12-01

    This paper discusses the concept of battery charging stations (BCSs), designed to service rural owners of battery power sources. Many such power sources now are transported to urban areas for recharging. A BCS provides the opportunity to locate these facilities closer to the user, is often powered by renewable sources, or hybrid systems, takes advantage of economies of scale, and has the potential to provide lower cost of service, better service, and better cost recovery than other rural electrification programs. Typical systems discussed can service 200 to 1200 people, and consist of stations powered by photovoltaics, wind/PV, wind/diesel, or diesel only. Examples of installed systems are presented, followed by cost figures, economic analysis, and typical system design and performance numbers.

    Sex partner meeting places may be important locales to access men who have sex with men (MSM) and implement targeted HIV control strategies. These locales may change over time, but temporal evaluations have not been performed. The objectives of this study were to describe the frequency of report of MSM sex partner meeting places over time and to compare frequently reported meeting places in the past 5 years and past year among newly HIV-diagnosed MSM in Baltimore City, Maryland. Public health HIV surveillance data including partner services information were obtained for this study from the Baltimore City Health Department from May 2009 to June 2014. A total of 869 sex partner meeting places were reported, including 306 unique places. Bars/clubs (31%) and Internet-based sites (38%) were the most frequently reported meeting place types. Over the 5-year period, the percentage of bars/clubs decreased over time and the percentage of Internet-based sites increased over time. Among bars/clubs, 4 of 5 of those most frequently reported in the past 5 years were also most frequently reported in the most recent year. Among Internet-based sites, 3 of 5 of those most frequently reported in the past 5 years were also in the top 5 most frequently reported in the past year. This study provides a richer understanding of sex partner meeting places reported by MSM over time and information to health departments on types of places to access a population at high risk for HIV transmission.

  14. The Impact of Drainage Network Structure on Flooding in a Small Urban Watershed in Metropolitan Baltimore, MD

    2006-12-01

    The impact of urban development on watershed-scale hydrology is examined in a small urban watershed in the Metropolitan Baltimore area. Analyses focus on Dead Run, a 14.3 km2 tributary of the Gwynns Falls, which is the principal study watershed of the Baltimore Ecosystem Study. Field observations of rainfall and discharge have been collected for storms occurring in the 2003, 2004, and 2005 warm seasons including the flood of record for the USGS Dead Run at Franklintown gage (7 July 2004), in which 5 inches of rain fell in less than 4 hours. Dead Run has stream gages at 6 locations with drainage areas ranging from 1.2 to 14.3 km2. Hydrologic response to storm events varies greatly in each of the subwatersheds due to the diverse development types located there. These subwatersheds range in land use from medium-density residential, with and without stormwater management control, to commercial/light industrial with large impervious lots and an extensive network of stormwater management ponds. The unique response of each subwatershed is captured using field observations in conjunction with the EPA Stormwater Management Model (SWMM), which routes storm runoff over the land surface and through the drainage network of a watershed. Of particular importance to flood response is the structure of the drainage network (both surface channels and storm drain network) and its connectivity to preferential flow paths within the watershed. The Dead Run drainage network has been delineated using geospatial data derived from aerial photography and engineering planning drawings. Model analyses are used to examine the characteristics of flow paths that control flood response in urban watersheds. These analyses aim to identify patterns in urban flow pathways and use those patterns to predict response in other urban watersheds.

  4. An assessment of the benefits of yellow Sigatoka (Mycosphaerella musicola control in the Queensland Northern Banana Pest Quarantine Area

    Directory of Open Access Journals (Sweden)

    David Cook

    2013-09-01

    Full Text Available The banana leaf spotting disease yellow Sigatoka is established and actively controlled in Australia through intensive chemical treatments and diseased leaf removal. In the State of Queensland, the State government imposes standards for de-leafing to minimise the risk of the disease spreading in 6 banana pest quarantine areas. Of these, the Northern Banana Pest Quarantine Area is the most significant in terms of banana production. Previous regulations imposed obligations on owners of banana plants within this area to remove leaves from plants with visible spotting on more than 15 per cent of any leaf during the wet season. Recently, this leaf disease threshold has been lowered to 5 per cent. In this paper we examine the likely impact this more-costly regulation will have on the spread of the disease. We estimate that the average net benefit of reducing the diseased leaf threshold is only likely to be $1.4million per year over the next 30 years, expressed as the annualised present value of tightened regulation. This result varies substantially when the timeframe of the analysis is changed, with shorter time frames indicating poorer net returns from the change in protocols. Overall, the benefit of the regulation change is likely to be minor.

  5. Investigation of the effects of irradiation for quarantine treatment purposes on food quality and hygiene in citrus fruits

    2010-01-01

    Mediterranean fruit fly (Ceratitis capitata) is a major problem in citrus production sector in Turkey. In order to overcome this problem, required irradiation doses were investigated for the quarantine treatment for 'Yafa' orange (Citrus sinensis (L) Osb.), 'Star ruby' grapefruit (Citrus paradisi Macf.); 'Satsuma' tangerine (Citrus reticulata Blanco) in this project. Chemical, physical and microbiological properties of unirradiated and irradiated (0.5, 1.0 and 1.5 kGy) fruits were determined in terms of weight loss, water soluble dry matter, pH, titratable acidity, alcohol insoluble pectin, apparent color of fruits, reducing sugar, total carotenoid, flavonoid, vitamin C contents, sensory properties of fruits, total aerob mesophilic bacteria and total yeast and mould counts of fruits. Results showed that, 0.1 kGy gamma irradiation dose is sufficient for effective quarantine treatment against the Mediterranean fruit fly in citrus fruits, low dose irradiation (≤1.0 kGy) applications had no detrimental effects on citrus fruits' quality except tangerines, microbial load of fruits were seriously affected by irradiation at 1.0 kGy. In addition, under this work we noticed that, irradiated citrus fruits could be detected by using DNA comet analysis method.

    The orbit maintenance problem is examined for two low-earth-orbiting space station concepts - the large, manned Space Operations Center (SOC) and the smaller, unmanned Science and Applications Space Platform (SASP). Atmospheric drag forces are calculated, and circular orbit altitudes are selected to assure a 90 day decay period in the event of catastrophic propulsion system failure. Several thrusting strategies for orbit maintenance are discussed. Various chemical and electric propulsion systems for orbit maintenance are compared on the basis of propellant resupply requirements, power requirements, Shuttle launch costs, and technology readiness.

    2014-01-01

    Autonomous Underwater Vehicles (AUVs) are becoming increasingly important for military surveillance and mine detection. Most AUVs are battery powered and have limited lifetimes of a few days to a few weeks. This greatly limits the distance that AUVs can travel underwater. Using a series of submerged AUV charging stations, AUVs could travel a limited distance to the next charging station, recharge its batteries, and continue to the next charging station, thus traveling great distances in a relatively short time, similar to the Old West “Pony Express.” One solution is to use temperature differences at various depths in the ocean to produce electricity, which is then stored in a submerged battery. It is preferred to have the upper buoy submerged a reasonable distance below the surface, so as not to be seen from above and not to be inadvertently destroyed by storms or ocean going vessels. In a previous invention, a phase change material (PCM) is melted (expanded) at warm temperatures, for example, 15 °C, and frozen (contracted) at cooler temperatures, for example, 8 °C. Tubes containing the PCM, which could be paraffin such as pentadecane, would be inserted into a container filled with hydraulic oil. When the PCM is melted (expanded), it pushes the oil out into a container that is pressurized to about 3,000 psi (approx equals 20.7 MPa). When a valve is opened, the high-pressure oil passes through a hydraulic motor, which turns a generator and charges a battery. The low-pressure oil is finally reabsorbed into the PCM canister when the PCM tubes are frozen (contracted). Some of the electricity produced could be used to control an external bladder or a motor to the tether line, such that depth cycling is continued for a very long period of time. Alternatively, after the electricity is generated by the hydraulic motor, the exiting low-pressure oil from the hydraulic motor could be vented directly to an external bladder on the AUV, such that filling of the bladder

    A 16-year-old boy presented with a number of asymptomatic pigmented macules on the volar aspect of his index fingers. Dermoscopy of each macule revealed a parallel ridge pattern of homogenous reddish-brown pigment. We propose that these lesions were induced by repetitive trauma from a Sony PlayStation 3 (Sony Corporation, Tokyo, Japan) vibration feedback controller. The lesions completely resolved following abstinence from gaming over a number of weeks. Although the parallel ridge pattern is typically the hallmark for early acral lentiginous melanoma, it may be observed in a limited number of benign entities, including subcorneal haematoma.

    1986-01-01

    A wide variety of space station applications for tethers were reviewed. Many will affect the operation of the station itself while others are in the category of research or scientific platforms. One of the most expensive aspects of operating the space station will be the continuing shuttle traffic to transport logistic supplies and payloads to the space station. If a means can be found to use tethers to improve the efficiency of that transportation operation, it will increase the operating efficiency of the system and reduce the overall cost of the space station. The concept studied consists of using a tether to lower the shuttle from the space station. This results in a transfer of angular momentum and energy from the orbiter to the space station. The consequences of this transfer is studied and how beneficial use can be made of it.

    Draper Station Analysis Tool (DSAT) is a computer program, built on commercially available software, for simulating and analyzing complex dynamic systems. Heretofore used in designing and verifying guidance, navigation, and control systems of the International Space Station, DSAT has a modular architecture that lends itself to modification for application to spacecraft or terrestrial systems. DSAT consists of user-interface, data-structures, simulation-generation, analysis, plotting, documentation, and help components. DSAT automates the construction of simulations and the process of analysis. DSAT provides a graphical user interface (GUI), plus a Web-enabled interface, similar to the GUI, that enables a remotely located user to gain access to the full capabilities of DSAT via the Internet and Webbrowser software. Data structures are used to define the GUI, the Web-enabled interface, simulations, and analyses. Three data structures define the type of analysis to be performed: closed-loop simulation, frequency response, and/or stability margins. DSAT can be executed on almost any workstation, desktop, or laptop computer. DSAT provides better than an order of magnitude improvement in cost, schedule, and risk assessment for simulation based design and verification of complex dynamic systems.

  13. Wind turbine power stations

    The Countryside Council for Wales (CCW's) policy on wind turbine power stations needs to be read in the context of CCW's document Energy:Policy and perspectives for the Welsh countryside. This identifies four levels of action aimed at reducing emission of gases which contribute towards the risk of global warming and gases which cause acid deposition. These are: the need for investment in energy efficiency; the need for investment in conventional power generation in order to meet the highest environmental standards; the need for investment in renewable energy; and the need to use land use transportation policies and decisions to ensure energy efficiency and energy conservation. CCW views wind turbine power stations, along with other renewable energy systems, within this framework. CCW's policy is to welcome the exploitation of renewable energy sources as an element in a complete and environmentally sensitive energy policy, subject to the Environmental Assessment of individual schemes and monitoring of the long-term impact of the various technologies involved.

    Pig (Sus sp.) and pig by-products are considered as najasa (impurities) in Islam and forbidden in Muslim consumer products. Animals fed on najasa are categorised as al-jallālah (contaminated animals) which are allowed to be consumed as long as they have been quarantined for a certain period of time. During this quarantine period the animals will have undergone a natural purification process or istihālah. African catfish (Clarias gariepinus) are commonly consumed in Malaysia and may be fed on najasa. This study was carried out to estimate the istihālah period for catfish after feeding with pig offal, based on the absence of pig DNA in catfish gut and to suggest the quarantine period in catfish fed with pig offal. The results indicated that the maximum istihālah period could reach 36h in the stomach, 6h in the midgut and less than 2h in the hindgut although in many cases shorter periods were observed. Based on these results it is estimated that the minimum quarantine period for catfish fed with pig offal is 1.5days. Copyright © 2012 Elsevier Ltd. All rights reserved.

    Argentina has quarantine restrictions in some markets due to the presence of two quarantine fruit fly pests: Ceratitis capitata and Anastrepha fraterculus. One alternative is the use of cold quarantine treatments during transport of the commodities. Since 1996, the Estacion Experimental Agroindustrial Obispo Colombres (EEAOC), Tucuman, Argentina, has developed different cold quarantine treatments for citrus. In the present work we present all the data the EEAOC generated in the last ten years in order to facilitate the development of such cold treatments. Fruit flies were obtained from the colonies reared at EEAOC. Four citrus species were analyzed: lemon, grapefruit, orange and tangerines. Different varieties were analyzed for each fruit species. Sensitivity trials aiming at determine the most tolerant stage as well as to asses if there is any influence of varieties on cold tolerance were performed. Finally we compared the tolerance to cold between the two species. Sensitivity trials showed that mature larvae (L3) are the most tolerant stage for both fruit fly species. There was no effect of the varieties and the two fruit fly species were equally sensible to cold. Our results provide strong evidence in favor of concluding that any cold treatment developed for C. capitata is effective for A. fraterculus. (author)

    The FAO/IAEA Program on 'Irradiation as a Quarantine Treatment of Mites, Nematodes and Insects other than Fruit Fly' has been implemented in 1992, and lasted up to the end of 1997. The Coordination Research Program put emphasis on the following aspects of research: (1) Determine criteria, e.g. inability to reproduce, for accepting irradiation as a quarantine treatment against quarantine pests; (2) Determine the effete of irradiation on the most resistant stage of these quarantine pests at the time of treatment; (3) Evaluate the quality of agricultural commodities irradiated at 2-3 times the dose(s) required to meet quarantine requirements; (4) Develop method(s) for identifying insects/other pests which were subjected to irradiation at a dose required for quarantine purposes. The followings are the most important achievements of the CRP: Generic dose for sterilization of both males and females of spider mites (Tetranychidae) was determined to be 320 Gy. With regard to insects other than fruit flies, it appears that a minimum dose of 300 Gy would cause either no adult emergence or sterility of most species of insects studied. Radiation doses required to cause complete mortality to various infective stages of plant parasitic nematodes is higher than 6 kGy. The minimum dose required to prevent gall development and reproduction of these nematodes is largely over 2 kGy, which is too high for most fresh plant materials. Thus, irradiation should be considered as an alternative to methyl bromide fumigation to control nematodes in non-perishable materials. While many fresh fruits and vegetables could tolerate radiation doses required for quarantine purposes, the response of various types of cut-flowers to irradiation varied widely. Some cut-flowers and ornamentals such as ferns, phoenix leaf, narcissus, tulips, carnation or red ginger were tolerant to radiation up to 700 Gy and more, others such as chrysanthemum, rose, lily, anthurium, dendrobium, gerbera did not tolerate

    We investigated the spatial distribution of heavy metal above-background (anthropic) contents of Cd, Co, Cu, Cr, Fe, Mn, Ni, Pb, Ti, V, and Zn in Baltimore City surface soils and related these levels to potential contaminating sources. Composite soil samples (0-10 cm depth) were digested using a nitric and hydrochloric extraction technique. Slightly more than 10% of plots exceeded United States Environmental Protection Agency screening guidelines for Pb. In a principal component analysis, the first component corresponded to Co, Cr, and Fe, which are constituents of local mafic rocks. The second component corresponded to Cu, Pb, and Zn which were significantly higher within than beyond a 100 m buffer of the major roads within the city; furthermore, Pb and Zn were higher in older residential lots. - Spatial distribution of metals in soils of an older US city (Baltimore) was affected by parent material, proximity to major roads, and housing age

    This paper describes research concerning the effects of human engineering design at local control stations (i.e., operator interfaces located outside the control room) on human performance and plant safety. The research considered both multifunction panels (e.g. remote shutdown panels) as well as single-function interfaces (e.g., valves, breakers, gauges, etc.). Changes in performance shaping factors associated with variations in human engineering at LCSs were estimated based on expert opinion. By means of a scaling procedure, these estimates were used to modify the human error probabilities in a PRA model, which was then employed to generate estimates of plant risk and scoping-level value/impact ratios for various human engineering upgrades. Recent documentation of human engineering deficiencies at single-function LCSs was also reviewed, and an assessment of the current status of LCSs with respect to human engineering was conducted

    In relation to modern demographic trends, evolving technologies and environment-friendly solutions increases the potential of rail considered as sustainable form of public transport. Contemporary tendencies of designing railway stations in Europe are focused on lowering energy consumption and reducing carbon emission. The main goal of the designers is to create a friendly and intuitive space for its users and at the same time a building that uses renewable energy sources and minimizes negative impact on the environment by the increase of biologically active areas, reuse of rainwater and greywater, innovative heating and cooling solutions and reduction of energy losses. The optimisation of a life circle in railway architecture introduces new approach to passenger service. Examples mentioned in the content of this article help to synthesize changes in approach to the design within the context of sustainability.

  2. Bradwell Nuclear Power Station

    1987-01-01

    When built, the Magnox reactors were expected to have operating lifetimes of 20-25 years. In order to satisfy the licensing authorities of their continued safety, long term safety reviews (LTSRs) are being carried out as the reactors reach 20 years of operation. This is the Nuclear Installations Inspectorate's (NII) summary report on Bradwell nuclear power station. The objectives of the LTSR are stated. A description of the plant is followed by an explanation of the statutory position on licensing. The responsibilities of the Central Electricity Generating Board (CEGB) and the NII are defined. From the examination of the CEGB's LTSR it is concluded that this generally confirms the validity of the existing safety case for present operation. However, some recommendations are made as to work required for reactor operation up to 1992. A summary of the NII findings is presented. This includes the reactor pressure circuit integrity, effects of ageing and in-service wear and radiation doses. (U.K.)

    The microfluidic probe (MFP) consists of a flat, blunt tip with two apertures for the injection and reaspiration of a microjet into a solution--thus hydrodynamically confining the microjet--and is operated atop an inverted microscope that enables live imaging. By scanning across a surface, the microjet can be used for surface processing with the capability of both depositing and removing material; as it operates under immersed conditions, sensitive biological materials and living cells can be processed. During scanning, the MFP is kept immobile and centered over the objective of the inverted microscope, a few micrometers above a substrate that is displaced by moving the microscope stage and that is flushed continuously with the microjet. For consistent and reproducible surface processing, the gap between the MFP and the substrate, the MFP's alignment, the scanning speed, the injection and aspiration flow rates, and the image capture need all to be controlled and synchronized. Here, we present an automated MFP station that integrates all of these functionalities and automates the key operational parameters. A custom software program is used to control an independent motorized Z stage for adjusting the gap, a motorized microscope stage for scanning the substrate, up to 16 syringe pumps for injecting and aspirating fluids, and an inverted fluorescence microscope equipped with a charge-coupled device camera. The parallelism between the MFP and the substrate is adjusted using manual goniometer at the beginning of the experiment. The alignment of the injection and aspiration apertures along the scanning axis is performed using a newly designed MFP screw holder. We illustrate the integrated MFP station by the programmed, automated patterning of fluorescently labeled biotin on a streptavidin-coated surface.

    eggs were found for the carmine spider mite and the two-spotted spider mite, respectively. In general, viability of eggs produced by mites irradiated as young females and old females was similar. The higher the dose of gamma radiation applied to adults of the spider mites, the higher the mortality of offspring during their embryonic development. However, a dose of 0.3 kGy did not cause complete sterility. To determine a sterilizing dose for both sexes, spider mites were irradiated with the following doses: 0.3, 0.31, 0.32, 0.33, 0.34, 0.35, and 0.4 kGy. When mites were treated with 0.30 and 0.31 kGy, a few eggs hatched. Data obtained indicate that a dose of 0.32 kGy is the lowest dose causing complete sterility in the carmine spider mite and the two-spotted spider mite, when both males and females were irradiated. This dosage could be used for irradiation as a quarantine treatment of horticultural products infested with spider mites. (author)

    Efforts to create more sustainable cities are evident in the proliferation of sustainability policies in cities worldwide. It has become widely proposed that the success of these urban sustainability initiatives will require city agencies to partner with, and even cede authority to, organizations from other sectors and levels of government. Yet the resulting collaborative networks are often poorly understood, and the study of large whole networks has been a challenge for researchers. We believe that a better understanding of citywide environmental governance networks can inform evaluations of their effectiveness, thus contributing to improved environmental management. Through two citywide surveys in Baltimore and Seattle, we collected data on the attributes of environmental stewardship organizations and their network relationships. We applied missing data treatment approaches and conducted social network and comparative analyses to examine (a) the organizational composition of the network, and (b) how information and knowledge are shared throughout the network. Findings revealed similarities in the number of actors and their distribution across sectors, but considerable variation in the types and locations of environmental stewardship activities, and in the number and distribution of network ties in the networks of each city. We discuss the results and potential implications of network research for urban sustainability governance.

The lifting condensation level (LCL heights were calculated and compared with the CBH. The monthly average observations show that PM2.5 decreases from 2007 to 2014 while there is no significant trend found for CBH and LCL. The variability of the LCL height agrees well with CBH but LCL height is systematically lower than CBH (~180 m lower. There was a significant negative correlation found between CBH–LCL and PM2.5. All of the cloud cases were separated into polluted and clean conditions based on the distribution of PM2.5 values. The distributions of CBH–LCL in the two groups show more cloud cases with smaller CBH–LCL in polluted conditions than in clean conditions.

    Trees and other vegetation absorb and capture air pollutants, leading to the common perception that they, and trees in particular, can improve air quality in cities and provide an important ecosystem service for urban inhabitants. Yet, there has been a lack of empirical evidence showing this at the local scale with different plant configurations and climatic regions. We studied the impact of urban park and forest vegetation on the levels of nitrogen dioxide (NO2) and ground-level ozone (O3) while controlling for temperature during early summer (May) using passive samplers in Baltimore, USA. Concentrations of O3 were significantly lower in tree-covered habitats than in adjacent open habitats, but concentrations of NO2 did not differ significantly between tree-covered and open habitats. Higher temperatures resulted in higher pollutant concentrations and NO2 and O3 concentration were negatively correlated with each other. Our results suggest that the role of trees in reducing NO2 concentrations in urban parks and forests in the Mid-Atlantic USA is minor, but that the presence of tree-cover can result in lower O3 levels compared to similar open areas. Our results further suggest that actions aiming at local air pollution mitigation should consider local variability in vegetation, climate, micro-climate, and traffic conditions.

    A 17-day pilot study investigating potential PM exposures of an elderly population was conducted near Baltimore, Maryland. Collection of residential indoor, residential outdoor, and ambient monitoring data associated with the subjects living at a common retirement facility was integrated with results from a paired epidemiological pilot study. This integration was used to investigate the potential pathophysiological health effects resulting from daily changes in estimated PM exposures with results reported elsewhere. Objectives of the exposure study were to determine the feasibility of performing PM exposure assessment upon an elderly population and establishing relationships between the various exposure measures including personal monitoring. PM 2.5 was determined to be the dominant outdoor size fraction (0.83 PM 2.5/PM 10 mass ratio by dichot monitoring). Individual 24-h PM 1.5 personal exposures ranged from 12 to 58 μg m -3. Comparison of data from matched sampling dates resulted in mean daily PM 1.5 personal, PM 2.5 outdoor, and PM 1.5 indoor concentrations of 34, 17, and 17 μg m -3, respectively. Activity patterns of the study population indicated a generally sedentary population spending a mean of 96% of each day indoors. Future studies would benefit from the use of a consistent sampling methodology across a larger number of PM measurement sites relevant to the elderly subjects, as well as a larger personal PM exposure study population to more successfully collect data needed in matched epidemiological-exposure studies.

    Abdominal fat is a major determinant of metabolic diseases in older individuals. Obesity and diabetes are associated with low serum amylase (SA) levels, but the association between SA and metabolic disease is poorly understood. We investigated the association of low SA with diabetes and sex-specific associations of serum amylase with abdominal fat in older adults. In community-dwelling volunteers from the Baltimore Longitudinal Study of Aging (778 participants, age 66.8±13.6years), we assessed abdominal fat by computed tomography and diabetes status using the American Diabetes Association criteria. Linear regression analyses assessed the cross-sectional associations between abdominal fat and SA, and logistic regression assessed the odds of diabetes, given low SA. In unadjusted analyses, individuals in the lowest SA quartile (abdominal subcutaneous adipose tissue (SAT, dm(2)) or BMI. In adjusted analyses, VAT and SAT were significantly associated with SA in both sexes. Among women, SA was more strongly associated with VAT than with SAT or BMI; VAT (β=-0.117±0.048, Pabdominal visceral fat. In women, SA was more strongly associated with VAT than with BMI or SAT. These findings provide motivation for future mechanistic studies on SA's role in metabolic diseases. Published by Elsevier Ireland Ltd.

    African American adults achieve smaller amounts of weight loss than their white counterparts when exposed to the same intervention and are more likely to regain weight during long-term follow-up. To identify perceived motivators, barriers, and facilitators to weight loss and behavior change among African American adults. Two focus groups were conducted between April and May 2015 at an urban community health center in Baltimore City, Maryland. A total of 13 participants took part in the discussions. Eligible participants were obese (BMI 30+) African American adults aged 21-70 who had at least one obesity-related comorbidity. Discussion questions were designed to identify the personal, social, and environmental factors that influence weight loss and behavior change among urban minority populations. Statements were first classified as a motivator, barrier, or facilitator, then divided further as a personal, social, or environmental factor influencing weight loss and behavior change. Among the findings, several novel motivators (reducing or eliminating medication, improving physical intimacy) and barriers (personal transportation, lack of access to scales) emerged that were not previously characterized in the existing literature. This study was intended to provide preliminary evidence that may be used to guide the development of innovative and culturally relevant weight-loss interventions in the future. Results are applicable to similar urban minority populations. Copyright © 2017 National Medical Association. Published by Elsevier Inc. All rights reserved.

  16. Calibrating and Validating a Simulation Model to Identify Drivers of Urban Land Cover Change in the Baltimore, MD Metropolitan Region

    2014-09-01

    Full Text Available We build upon much of the accumulated knowledge of the widely used SLEUTH urban land change model and offer advances. First, we use SLEUTH’s exclusion/attraction layer to identify and test different urban land cover change drivers; second, we leverage SLEUTH’s self-modification capability to incorporate a demographic model; and third, we develop a validation procedure to quantify the influence of land cover change drivers and assess uncertainty. We found that, contrary to our a priori expectations, new development is not attracted to areas serviced by existing or planned water and sewer infrastructure. However, information about where population and employment growth is likely to occur did improve model performance. These findings point to the dominant role of centrifugal forces in post-industrial cities like Baltimore, MD. We successfully developed a demographic model that allowed us to constrain the SLEUTH model forecasts and address uncertainty related to the dynamic relationship between changes in population and employment and urban land use. Finally, we emphasize the importance of model validation. In this work the validation procedure played a key role in rigorously assessing the impacts of different exclusion/attraction layers and in assessing uncertainty related to population and employment forecasts.

    When information on plans to build a power station in Trebisov first appeared reactions differed. A 40-billion investment in a town with more than 20% unemployment seemed attractive. But some people did not like the idea of having a power plant located in the town. Around one year after the investment was officially announced TREND returned to Trebisov. In the meantime the investor has managed to overcome one of the biggest obstacles on its way to building a new power plant. The ministry responsible gave the environmental study a positive rating. But objectors are still not sure that everything is fine. They claim that the study misinterprets data and that the ministry did not show expertise when evaluating it. 'Is it possible that a coal power plant located in a town would have twice as many positive effects on peoples' health than negative ones? Why don't we build them everywhere?'asked the chairman of the civic society, Trebisov nahlas, Gejza Gore. The developer of the project, Ceskoslovenska energeticka spolocnost (CES), Kosice is fighting back and claims that their counterpart lacks professional arguments. In the meantime it is preparing for area management proceedings. Trebisov is also involved in the discussion and claims that the town planning scheme does not include such a project. The Ministry of Construction has a different opinion. In the opinion of the Ministry the town planning scheme allows a 885-megawatt power plant to be built only a few hundred meters away from housing estates. (author)

    Stote, J.J.

    1988-01-01

    At the Shippingport Station Decommissioning Project, the central idea of the communications program that was developed for use was purposely designed to be as uncomplicated as possible. The central theme, that was developed and communicated, is that all nuclear plants will someday need to be retired and also decommissioned. The Shippingport Plant, originally constructed as a demonstration nuclear power plant, was now being decommissioned as a demonstration to the world-wide nuclear industry that this evolution can be done in a safe and cost-effective manner. Furthermore, the technology currently exists to complete this process. The new phase of the communications program was initiated even before the responsibility for the plant was transferred from Duquesne Light to GE. With such a change forthcoming, it was necessary to inform local officials of these plans, and the reasons for them. Equally important was the need to inform a variety of agencies and offices in the three-state area of the changes, and the continuing need to involve them in the Site Emergency Plan. This document was also revised in recognition of changing site conditions, as well as the changes in responsibility. 1 ref

    A description is given of the design, construction and initial testing of two types of Seismometer Array Station Processor (SASP), one to work with data stored on magnetic tape in analogue form, the other with data in digital form. The purpose of a SASP is to detect the short period P waves recorded by a UK-type array of 20 seismometers and to edit these on to a a digital library tape or disc. The edited data are then processed to obtain a rough location for the source and to produce seismograms (after optimum processing) for analysis by a seismologist. SASPs are an important component in the scheme for monitoring underground explosions advocated by the UK in the Conference of the Committee on Disarmament. With digital input a SASP can operate at 30 times real time using a linear detection process and at 20 times real time using the log detector of Weichert. Although the log detector is slower, it has the advantage over the linear detector that signals with lower signal-to-noise ratio can be detected and spurious large amplitudes are less likely to produce a detection. It is recommended, therefore, that where possible array data should be recorded in digital form for input to a SASP and that the log detector of Weichert be used. Trial runs show that a SASP is capable of detecting signals down to signal-to-noise ratios of about two with very few false detections, and at mid-continental array sites it should be capable of detecting most, if not all, the signals with magnitude above msub(b) 4.5; the UK argues that, given a suitable network, it is realistic to hope that sources of this magnitude and above can be detected and identified by seismological means alone.

  5. The Trencin water power station

    International Nuclear Information System (INIS)

    2005-01-01

    This leaflet describes the Trencin water power station. The Trencin water power station was built seven years after the Dubnica nad Vahom water power station started its operation and was the last stage of the first and the oldest derived cascade of water power stations on the Vah River. After completing water power stations at Ladce (1936), Ilava (1946) and Dubnica nad Vahom (1949) and before constructing the Trencin water power station, the whole second derived cascade of water power stations including water power stations at Kostolna, Nove Mesto nad Vahom and Horna Streda was built as soon as possible mainly because the need to get compensation for discontinued electricity supplies as well as energetic coal from the Czech Republic. Hereby, experiences from the construction of previous grades were used, mainly as far as the dimensioning was concerned, as the fi rst installed power stations had, in comparison with the growing requirements on the electricity supplies, very low absorption capacity - only 150 m 3 .s -1 . Thus the Trencin power station (original name was the Skalka power station) was already dimensioned for the same absorption capacity as the cascade located downstream the river, that is 180 m 3 .s -1 . That was related also to growing demands on electricity supplies during the peaks in the daily electric system load diagram, and thus to the transfer from continuous operation of the water power station to semi-peak or even peak performance. According to the standards of power station classification, the Trencin water power station is a medium size, low pressure, channel power station with two units equipped by Kaplan turbines and synchronous hydro-alternators. The water power station installed capacity is 16.1 MW in total and its designed annual production of electrical energy for medium water year is 85,000 MWh, while the average annual production during the last 30 years is 86,252 MWh. Installed unit has a four-blade Kaplan turbine with the diameter

    Propulsion system requirements to support Low Earth Orbit (LEO) manned space station development and evolution over a wide range of potential capabilities and for a variety of STS servicing and space station operating strategies are described. The term space station and the overall space station configuration refers, for the purpose of this report, to a group of potential LEO spacecraft that support the overall space station mission. The group consisted of the central space station at 28.5 deg or 90 deg inclinations, unmanned free-flying spacecraft that are both tethered and untethered, a short-range servicing vehicle, and a longer range servicing vehicle capable of GEO payload transfer. The time phasing for preferred propulsion technology approaches is also investigated, as well as the high-leverage, state-of-the-art advancements needed, and the qualitative and quantitative benefits of these advancements on STS/space station operations. The time frame of propulsion technologies applicable to this study is the early 1990's to approximately the year 2000.

    Objective To investigate risk factors associated with esotropia or exotropia in infants and young children. Design Population-based cross-sectional prevalence study. Participants Population-based samples of 9970 children ages 6 to 72 months from California and Maryland. Methods Participants were preschool African-American, Hispanic, and non-Hispanic white children participating in the Multiethnic Pediatric Eye Disease Study and the Baltimore Eye Disease Study. Data were obtained by parental interview and ocular examination. Odd ratios and 95% confidence intervals were calculated to evaluate the association of demographic, behavioral, and clinical risk factors with esotropia and exotropia. Main Outcome Measures Odds ratios (ORs) for various risk factors associated with esotropia or exotropia diagnosis based on cover testing. Results In multivariate logistic regression analysis, esotropia was independently associated with prematurity, maternal smoking during pregnancy, older preschool age (48–72 months), anisometropia, and hyperopia. There was a severity-dependent association of hyperopia with the prevalence of esotropia, with ORs increasing from 6.4 for 2.00 Diopters (D) to strabismus, female sex, astigmatism (OR 2.5 for 1.50 to <2.50 D, and 5.9 for ≥ 2.5 D of astigmatism), and aniso-astigmatism in the J0 component (OR ≥ 2 for J0 aniso-astigmatism ≥ 0.25 D). Conclusions Prematurity and maternal smoking during pregnancy are associated with a higher risk of having esotropia and exotropia. Refractive error is associated in a severity-dependent manner to the prevalence of esotropia and exotropia. Because refractive error is correctable, these risk associations should be considered when developing guidelines for the screening and management of refractive error in infants and young children children.

    The W.R. Grace Company, Davison Chemical Division, conducted developmental research and extraction of thorium from monazite ore at its Curtis Bay facility in Baltimore, Maryland, during the 1950s under contract to the Atomic Energy Commission (AEC). Only one of the numerous buildings on the site was used for these operations. A 1979 aerial survey of the site for the Department of Energy (DOE) indicated that a comprehensive ground survey was required to determine whether or not any contamination remained from the AEC activities in that building. A radiological scoping survey performed later that year for DOE by a team from the Measurement Applications and Development Group of the Health and Safety Research Division, Oak Ridge National Laboratory (ORNL), disclosed surface contamination (alpha) levels in excess of DOE criteria on all five levels of the building. As a result of this finding, two additional surveys were performed in 1986 by ORNL at the request of DOE to evaluate any present or potential health risk. They are detailed in this report. The results of the 1986 surveys revealed several areas having elevated levels of radiation as a result of significant quantities of thorium on some building surfaces such as floors and ceiling beams. Most areas were small spots and in locations of low occupancy; thus, the possibility for significant exposure to workers was judged to be low. To confirm this evaluation, annual radiation exposure estimates for workers frequenting the few, larger contaminated areas on the site were derived using ORNL survey data and occupancy factors provided by the W.R. Grace Company. Estimates ranged from 27 to 41 mrem/yr or a maximum of 41% of the basic dose limit of 100 mrem/yr for members of the general public. 2 refs., 14 figs., 8 tabs

    Urban streams receive a myriad of chemical inputs from the surrounding landscape due to altered lithology (asphalt, concrete), leaky sewage infrastructure, and other human activities (road salt, fertilizer, industrial wastes, wastewater effluent), potentially leading to multiple chemical stressors occurring simultaneously. To evaluate potential drivers of water chemistry change, we used approximately 20 years of weekly water chemistry monitoring data from streams in the Baltimore Ecosystem Study (BES) to quantify trends of annual loads and flow-weighted concentrations for multiple solutes of interest, including nitrate (NO3-), phosphate (PO43-), total nitrogen (TN), total phosphorus (TP), chloride (Cl-), and sulfate (SO42-) and subsequently examined various gray and green infrastructure characteristics at the watershed scale. For example, we quantified annual volume and duration of reported sanitary sewer overflows (SSO) and cumulative storage volume and area of various best management practices (BMPs). Site- and solute-specific trends differed, but across our monitoring network we found evidence for decreasing annual export for multiple solutes. Additionally, we found that changes in gray- and green-infrastructure characteristics were related to changes in water quality at our most downstream (most urban) monitoring site. For example, annual NO3- loads increased with longer cumulative SSO duration, whereas annual PO43- and TP loads decreased with a cumulative BMP area in the watershed. Further, we used same long-term water chemistry data and multivariate analyses to investigate whether urban streams have unique water chemistry fingerprints representing the multiple chemical stressors at a given site, which could provide insight into sources and impacts of water-quality impairment. These analyses and results illustrate the major role gray and green infrastructure play in influencing water quality in urban environments, and illustrate that focusing on a variety of

    The 2000 Pew reports became the impetus for the National Environmental Public Health Tracking (EPHT) Program, but there was no mention that Spanish-speaking persons are at increased risk of exposure to environmental hazards. To undertake successful EPHT outreach on Spanish-speaking persons (Hispanics), it is necessary to better understand their environmental health profile and barriers to health care access. Behavioral Risk Factor Surveillance System (BRFSS) survey questions were administered orally in Spanish to Spanish-speaking study participants. Volunteers were tested at a non-for-profit social service and referral agency in Baltimore. To control for acculturation, only Spanish-speaking persons who had lived in the United States for less than 10 years were selected. Responses to 40 BRFSS survey questions asked during the assessment and completion of 3 intervention activities. This study provides new information about Spanish-speaking persons, most of whom (85.3%) would not have been included in the landline administration of the BRFSS survey. Although 29.9% of the participants reported indoor pesticide use and another 9.2% reported outdoor pesticide use, lifetime (3.5%) and current (1.2%) asthma prevalence was significantly lower than asthma prevalence reported by Maryland Hispanics and all Maryland residents. There were significantly lower cholesterol screening (21.5%) and a significantly higher prevalence of diabetes (12.5%) in Spanish-speaking participants than in Maryland Hispanics and all Maryland residents. Among study participants, only 7.8% had health insurance and 39.9% reported that they could not see a doctor. Of the 3 outreach efforts completed, the most promising one involved asking Spanish-English-speaking health care professionals to distribute Spanish comic books about pesticides exposures and health outcomes in community settings where Spanish-only speakers and children were found.

    There has been a dramatic increase in drug overdose deaths in the United States. In the current study, the authors examined factors associated with witnessing a drug overdose. A sample of 450 substance users in Baltimore, Maryland, were recruited for a behavioral intervention and were administered a survey. Multinomial logistic regression models were used to compare participants who never witnessed a drug overdose with those who witnessed one in the prior 6 months and those who witnessed an overdose over 6 months ago. Most (58%) participants were male, 40% experienced homelessness in the prior 6 months, 63% reported a history of heroin injecting, 84% had snorted heroin, 75% reported witnessing a drug overdose, and 38% experienced an overdose. In multinomial logistic regression models, witnessing an overdose in the past 6 months was associated with number of different types of places where drugs were used (adjusted odds ratio [aOR] = 1.34), history of experiencing an overdose (aOR = 1.80), injecting heroin and/or speedball (aOR = 1.78), and snorting heroin (aOR = 1.54). Witnessing an overdose more than 6 months ago was associated with number of different places where drugs were used (aOR = 1.25), history of experiencing an overdose (aOR = 1.61), snorting heroin (aOR = 1.42), and injecting heroin or speedball (aOR = 1.47). These data suggest that people who engage in more public and frequent drug use, and hence are more likely to witness an overdose, should be targeted for interventions to prevent and treat drug overdose.

  13. Gamma irradiation as a quarantine treatment of apples infested with diapausing eggs of the European red spider mite, Panonychus ulmi (Koch) (Acarina: Tetranychidae)

    1997-01-01

    Viable eggs of the European red mite, Panonychus ulmi (Koch), on apples have been the concern of several importing countries and exports require preshipment, phytosanitary treatment to reduce or eliminate live eggs. Because fumigation is often detrimental to the commodity appearance and shelf-life, resulting in a loss of commercial value, there is a need for alternatives for chemical pest control as a quarantine treatment, and irradiation could be a new strategy method. The data obtained indicate that a dose of gamma radiation equal to or higher than 0.15 kGy seems to be adequate to prevent post-diapause hatching of wintering eggs of the European red mite. Thus, this dose is suggested for quarantine treatment of apples infested with wintering eggs of the European red mite. (author)

    To pre-establish an alternative technique to the toxic fumigant, methyl bromide which is the current quarantine measure of agricultural products for export, some selected agricultural products, such as apple and pear, were subjected to a preliminary study to confirm the comparative effects of gamma irradiation and MeBr fumigant on their disinfestation and quality, thereby preparing the basic data for the practical approach. Current quarantine activities were examined and the related limitations were investigated. Quarantine-related pests were investigated on their radiosensitivity and disinfestation effects by both treatments. The pests in apple and pear, Tetranychus urticae Koch, Panonychus ulmis Koch revealed a 100% mortality at around 17 days after irradiation of 3 kGy but it was too high dose for apple and pear. Tetranychus urticae Koch, Panonychus ulmi Koch from both apple and pear showed an increased mortality when exposed to 1 {approx} 2 kGy irradiation, resulting in apparent mortality 1 month later. 1 {approx} 2 kGy irradiation could be recommended for apple and pear. Current fumigation was perfect in its disinfesting capability, but it caused the detrimental effects on physical quality of agricultural produce. Whereas, irradiation doses suitable for controlling the pests did not induce any significant changes in the quality of the samples. 40 refs., 64 figs., 160 tabs. (Author)

    The scope of this project was changed during the course of the project. Phase I of the project was to construct a site similar to the site at Central West Virginia Regional Airport in Charleston, WV to show that duplication of the site was a feasible method of conducting hydrogen stations. Phase II of the project was necessitated due to a lack of funding that was planned for the development of the station in Morgantown. The US Department of Energy determined that the station in Charleston would be dismantled and moved to Morgantown and reassembled at the Morgantown site. This necessitated storage of the components of the station for almost a year at the NAFTC Headquarters which caused a number of issues with the equipment that will be discussed in later portions of this report. This report will consist of PHASE I and PHASE II with discussions on each of the tasks scheduled for each phase of the project.

    Anthropogenic activities alter the urban surface and surface atmosphere, generating heat and pollutants that have known detrimental impacts on health. Monitoring these environmental variables in urban environments is made difficult by the spatial heterogeneity of urban environments, meaning that two nearby locations may have significantly different temperatures, humidities, or gas concentrations. Thus, urban monitoring often requires more densely placed monitors than current standards or budgets allow. Recent advances in low-cost sensors and Internet of Things (IoT) enabled hardware offer possible solutions. We present an autonomous wireless, open-source, IoT-enabled environmental monitor called a WeatherCube, developed for the Greater Baltimore Open Air project, funded in part by the EPA SmartCity Challenge. The WeatherCube is suitable for urban monitoring and capable of measuring meteorological variables (temperature and humidity) as well as air quality (ozone, nitrogen dioxide, and sulfur dioxide). The WeatherCube devices were built in collaboration with Johns Hopkins University, local government, and community members, including through an innovative job training program. Monitors are hosted by community partners and libraries throughout Baltimore city and surrounding communities. We present the first wave of data collected by the Greater Baltimore Open Air project and compare it to data collected by the Maryland Department of the Environment (MDE). Additionally, we will provide an overview of our experience engaging with the local makers, citizen scientists, and environmental groups to improve their urban environmental monitoring. By developing low-cost devices tailored for urban environmental monitoring, we present an innovative model for both conducting research and community outreach.

Cost estimating methodologies and the way in which operations costs affect the design and development process are examined.

  11. Advances in power station construction

    International Nuclear Information System (INIS)

    Anon.

    1986-01-01

    This book is about power stations - specifically about the construction of modern power stations by the Central Electricity Generating Board in England and Wales over the past decade. It describes the work of the CEGB's Generation Development and Construction Division, perhaps better known throughout the world as simply 'Barnwood' where it has its Headquarters in Gloucester, UK. Barnwood was formed in the early 1970s to concentrate the CEGB's then dispersed engineering construction resources to cope with the smaller number but greatly increased size and complexity of modern power station projects. Perhaps uniquely over the ten years since its formation Barnwood has managed the construction of all types of station; coal-fired, oil-fired, nuclear, pumped storage and hydro. This book tells the story of these various projects and gives detailed descriptions of the respective stations. However, it is not intended as a comprehensive description of power station technology. Rather it is intended to convey the scale of such projects and the many decisions and compromises which have to be made in the course of managing their construction

  14. The Miksova water power station

    International Nuclear Information System (INIS)

    2005-01-01

    This leaflet describes the Miksova water power station. The Miksova water power station is part of the second derived cascade of hydro power stations on the river Vah. It was built at the end of a huge development in Slovak hydro-energy in the late 1950's and the beginning of the 1960's. It is the second water power station on this derived cascade, which is situated downstream the Hricov reservoir and water power station. At the power station, three turbine sets with vertical Kaplan turbines are installed with a total power output of 3 x 31.2 = 93.6 MW. With this power output the Miksova water power station (Miksova I) was the biggest water power station in the Slovak Republic until the construction of Pumping water power station Liptovska Mara. And it is still the biggest channel water power station on the Vah so far. It was put into operation during the period 1963 to 1965. There are three turbine sets with Kaplan turbines from CKD Blansko, with a synchronous hydro-alternator installed in the power station. Their installed capacity is 93.6 MW in total and the projected annual production of electrical energy is 207 GWh. The turbines are fi ve-bladed (on the Hricov and Povazska Bystrica water power stations they are four-bladed) and the impeller wheel has a diameter of 4800 mm. They are designed for extension of the head from 24.1 to 22.21 m and each of them has an absorption capacity of 134 m 3 .s -1 nd a nominal operating speed of 2.08 m 3 .s -1 , runaway speed 4.9 m 3 .s -1 . Each synchronous hydro-alternator has a maximum power output of 31.2 MW, a nominal voltage of 10.5 kV and power factor cos φ of 0.8. Power from the power station is led out through 110 kV switchgear. The water power station operates under automatic turbine mode of operation with remote indication and control from the Dispatch Centre at Vodne elektrarne, in Trencin. From start of operation until the end of 2003 all three turbine sets operated for a total of 450,500 running hours and the

    2015-12-01

    As objectives of development are high for renewable energies (they are supposed to cover 50 per cent of new energy needs by 2035), pumped energy transfer stations are to play an important role in this respect. The author first discusses the consequences of the development of renewable energies on the exploitation of electric grids: issue of intermittency for some of them, envisaged solutions. Then, he addresses one of the solutions: the storage of electric power. He notices that increasing the potential energy of a volume of water is presently the most mature solution to face massive needs of the power system. Dams and pumped energy transfer stations represent now almost the whole installed storage power in the world. The author then presents these pumped energy transfer stations: principle, brief history (the first appeared in Italy and Switzerland at the end of the 1890's). He indicates the various parameters of assessment of such stations: maximum stored energy, installed power in pumping mode and turbine mode, time constant, efficiency, level of flexibility. He discusses economic issues. He describes and comments the operation of turbine-pump groups: ternary groups, reversible binary groups. He discusses barriers to be overcome and technical advances to be made for varying speed groups and for marine stations. He finally gives an overview (table with number of stations belonging to different power ranges, remarkable installations) of existing stations in China, USA, Japan, Germany, Austria, Spain, Portugal, Italy, Switzerland, France and UK, and indicate predictions regarding storage needs at the world level. Some data are finally indicated for the six existing French installations

    Utilization of phytosanitary irradiation as a potential treatment to disinfest agricultural commodities in trade has expanded rapidly in the recent years. In this study, red mites (Tetranychus sp) isolated from cut Chrysanthemums were treated by electron beam irradiation at doses of 100, 200, 300 and 400 Gy. After irradiation, they were kept at room temperature to determine the effects of electron beam irradiation on red mite at different developmental stages (eggs, nymphs and adults) and the reproduction of female adults. The results showed that the pattern of tolerance to irradiation in red mite was eggs < 2nd instars < adults, in which the adults were the most tolerance stage. The number of eggs laid by the irradiated female mites and the hatching rate significantly decreased when the irradiation dose increased. The hatching rate of eggs at 300 Gy was 4.25% and no larvae F_1 survived during observation time. It could be concluded that 300 Gy is the effective quarantine dose for red mite infesting on cut chrysanthemums. (author)

    The tebo worms or butterworms (Chilecomadia moorei) are widely used in Chile in fishing, and so are in the international markets although there are some countries, that use these species, to a less extent for preparing food reptiles. Some foreign countries requirements demand, from the exporters, to carry out quarantine treatments related to the sterilization by ionizing energy, however customers need to make sure about their products safety and that is why it is compulsory to establish limits in connection with worms' irradiation resistance. The irradiation effect on a worms sample using doses of 0.3; 0.45; 0.6 and 0.9 kGy was studied macroscopically, after 1 hour, and then 30, 60 and 90 days after the treatment. One of the equipment utilized had a Cobalt 60 source, where as the other one had Cesium 137 irradiators, with a dose rate of 42.7 Gy minute (min) -1 and 37.1 Gy min -1 , respectively. The results concluded that tebo worms can resist more than 3 times the doses suggested by the meta countries without reducing the population drastically, nevertheless it is required to increase the number of worms to be analyzed in order to validate the findings.

    2005-01-01

    Khapra beetle, Trogoderma granarium everts is apparently native to India. Current quarantine regulations for the US recognize 25 countries as harboring endemic populations of khapra beetle: Afghanistan, Algeria, Bangladesh, Burkina Faso, Cyprus, Egypt, India, Iran, Iraq, Israel, Libya, Mali, Mauritania, Morocco, Myanmar, Niger, Nigeria, Pakistan, Saudi Arabia, Senegal, Sri Lanka, Sudan, Syria, Tunisia and Turkey. The beetle has developed resistance to many insecticides particularly to phosphine alone and malathion. Fumigation with methyl bromide provides good control in a variety of commodities, however, its production and importation has been restricted since it is an ozone depleting substance. Further, for effective treatment of storage facilities and ships require use of high concentrations, which has raised concerns among the public. Potential alternatives to the use of methyl bromide may need to be tested for effectiveness against this beetle prior to implementation. In view of this, studies were undertaken to record the effectiveness of different doses of gamma radiation (40-100, 250, 500, 750 and 1000 Gy) for the control of this important pest in grain storage.

    Full Text Available Phytophthora infestans (mont de Bary is a pathogen of great concern across the globe, and accurate detection is an important component in responding to the outbreaks of potential disease. Although the molecular diagnostic protocol used in regulatory programs has been evaluated but till date methods implying direct comparison has rarely used. In this study, a known area soil samples from potato fields where light blight appear every year (both A1 and A2 mating type was assayed by soil bait method, PCR assay detection and quantification of the inoculums. Suspected disease symptoms appeared on bait tubers were further confirmed by rapid PCR, inoculums were quantified through Real Time PCR, which confirms presence of P. infestans. These diagnostic methods can be highly correlated with one another. Potato tuber baiting increased the sensitivity of the assay compared with direct extraction of DNA from tuber and soil samples. Our study determines diagnostic sensitivity and specificity of the assays to determine the performance of each method. Overall, molecular techniques based on different types of PCR amplification and Real-time PCR can lead to high throughput, faster and more accurate detection method which can be used in quarantine programmes in potato industry and diagnostic laboratory.

  1. The response of longan fruit to cold and gamma irradiation treatments for quarantine eradication of exotic pests

    McGuire, R.G.

    1998-01-01

    In separate treatments, fruit of Dimocarpus longan Lour. were subjected to 15 d at 1.1°C or to gamma irradiation from a 60 Co source. Cold-treated fruit were not significantly different from untreated fruit in characteristics including decay susceptibility, firmness, and the percentage of total soluble solids and acids in the pulp, but treatment produced patches of bronze discolouration on the pericarp. Gamma irradiation at 100, 200, or 300 Gy did not significantly affect susceptibility to decay or injure fruit, nor were firmness or external and interior colour reduced. Irradiated fruit, however, had lower percentages of total soluble solids and acids, with a concomitantly higher pH, but sensory evaluations could not differentiate these fruits from untreated ones. Due primarily to the injurious effects of cold treatment on the longan pericarp, irradiation at 100 to 300 Gy would be preferable for maintaining quality of longans that require quarantine treatment for the eradication of exotic pests and are destined for the fresh market.

    Full Text Available The mixture (MX of acetic acid (AA and lactic acid (LA was examined for its effectiveness in the control of the pine wood nematode Bursaphelenchus xylophilus contaminated in cymbidium culture medium. Nematode mortality in vitro was nearly 100% in AA and MX at the concentrations of 5.0-1.0% (pH 2.6 – 4.2 and in LA only at 5.0% (pH 3.5, but lowered at concentrations of 0.5-0.1% (pH 5.1-6.9 more significantly in LA than AA and MX. MX of most concentrations caused higher nematode mortality than the average response to AA and LA. All treatments of MX (0.5% and 0.25%, fosthiazate (standard and double concentrations and culture dilution of Paenibacillus polymyxa GBR-1 (107colony-forming units/ml reduced significantly the nematode populations in the cymbidium culture medium, compared to non-treatment control, with no significant difference among the treatments. No phytotoxicity occurred in all treatments. pH of the medium with the time after treatment and growths of 2-year-old cymbidium were not significantly different among treatments. Considering the safety and price of the organic acids, use of MX in the processes for culturing cymbidium may be a practically reliable and eco-friendly way in the control of the quarantine nematode in cymbidium.

    Banks, William S.L.; Battigelli, David A.

    2002-01-01

    The U.S. Geological Survey, in cooperation with the Maryland Department of the Environment and the Wisconsin State Laboratory of Hygiene, conducted a study to characterize the occurrence and distribution of viral contamination in small (withdrawing less than 10,000 gallons per day) public water-supply wells screened in the shallow aquifer in the Piedmont Physiographic Province in Baltimore and Harford Counties, Maryland. Two hundred sixty-three small public water-supply wells were in operation in these counties during the spring of 2000. Ninety-one of these sites were selected for sampling using a methodology that distributed the samples evenly over the population and the spatial extent of the study area. Each site, and its potential susceptibility to microbiological contamination, was evaluated with regard to hole depth, casing interval, and open interval. Each site was evaluated using characteristics such as on-site geology and on-site land use.Samples were collected by pumping between 200 and 400 gallons of untreated well water through an electropositive cartridge filter. Water concentrates were subjected to cell-culture assay for the detection of culturable viruses and reverse-transcription polymerase chain reaction/gene probe assays to detect viral ribonucleic acid; grab samples were analyzed for somatic and male-specific coliphages, Bacteroides fragilis, Clostridium perfringens, enterococci, Escherichia coli, total coliforms, total oxidized nitrogen, nitrite, organic nitrogen, total phosphate, ortho-phosphate, calcium, magnesium, sodium, potas-sium, chloride, sulfate, iron, acid-neutralizing capacity, pH, specific conductance, temperature, and dissolved oxygen.One sample tested positive for the presence of the ribonucleic acid of rotavirus through poly-merase chain-reaction analysis. Twenty-nine per-cent of the samples (26 of 90) had bacterial con-tamination. About 7 percent of the samples (6 of 90) were contaminated with either male-specific coliphage

    To determine whether living in a food swamp (≥4 corner stores within 0·40 km (0·25 miles) of home) or a food desert (generally, no supermarket or access to healthy foods) is associated with consumption of snacks/desserts or fruits/vegetables, and if neighbourhood-level socio-economic status (SES) confounds relationships. Cross-sectional. Assessments included diet (Youth/Adolescent FFQ, skewed dietary variables normalized) and measured height/weight (BMI-for-age percentiles/Z-scores calculated). A geographic information system geocoded home addresses and mapped food deserts/food swamps. Associations examined using multiple linear regression (MLR) models adjusting for age and BMI-for-age Z-score. Baltimore City, MD, USA. Early adolescent girls (6th/7th grade, n 634; mean age 12·1 years; 90·7 % African American; 52·4 % overweight/obese), recruited from twenty-two urban, low-income schools. Girls' consumption of fruit, vegetables and snacks/desserts: 1·2, 1·7 and 3·4 servings/d, respectively. Girls' food environment: 10·4 % food desert only, 19·1 % food swamp only, 16·1 % both food desert/swamp and 54·4 % neither food desert/swamp. Average median neighbourhood-level household income: $US 35 298. In MLR models, girls living in both food deserts/swamps consumed additional servings of snacks/desserts v. girls living in neither (β=0·13, P=0·029; 3·8 v. 3·2 servings/d). Specifically, girls living in food swamps consumed more snacks/desserts than girls who did not (β=0·16, P=0·003; 3·7 v. 3·1 servings/d), with no confounding effect of neighbourhood-level SES. No associations were identified with food deserts or consumption of fruits/vegetables. Early adolescent girls living in food swamps consumed more snacks/desserts than girls not living in food swamps. Dietary interventions should consider the built environment/food access when addressing adolescent dietary behaviours.

  5. Comparing MODIS-Terra and GOES surface albedo for New York City NY, Baltimore MD and Washington DC for 2005

    The NOAA GOES Aerosol and Smoke Product (GASP) is a product displaying the Aerosol Optical Depth (AOD) over the United States. The GASP retrieval involves discriminating the upwelling radiance from the atmosphere from that of the variable underlying surface. Unlike other sensors with more visible and near- infrared spectral channels such as MODIS, the sensors on GOES 8 through 12 only have one visible and a several far infrared channels. The GASP algorithm uses the detection of the second-darkest pixel from the visible channel over a 28-day period as the reference from which a radiance look-up table gives the corresponding AOD. GASP is reliable in capturing the AOD during large events. As an example, GASP was able to precisely show the Alaska and British Columbia smoke plume advecting from Alaska to the northeastern U.S. during the summer of 2004. Knapp et al. (2005) has shown that the AOD retrieval for GOES- 8 is within +/-0.13 of AERONET ground data with a coefficient of correlation of 0.72. Prados (this meeting) will update that study. However, GASP may not be as reliable when it comes to observing smaller AOD events in the northeast where the surface brightness is relatively high. The presence of large cities, such as New York, increases the surface albedo and produces a bright background against which it may be difficult to deduce the AOD. The Moderate Resolution Imaging Spectroradiometer (MODIS) sensor on the Earth Observing System Terra and Aqua platforms provides an independent measurement of the surface albedo at a resolution greater than available on GOES. In this research, the MODIS and GOES surface albedo product for New York, Washington and Baltimore are compared in order to see how we can improve the AOD retrieval in urban areas for air quality applications.

    1985-01-01

    The U.S. Department of Energy is in the process of decommissioning the Shippingport Atomic Power Station located on the Ohio River, 30 miles northwest of Pittsburgh, Pennsylvania. The Shippingport Station is the first commercial size nuclear power plant to undergo decommissioning in the United Staes. The plant is located on approximately 7 acres of land owned by the Duquesne Light Company (DLC) and leased to the U.S. Government. DLC operates two nuclear power plants, Beaver Valley 1 and 2, located immediately adjacent to the site and the Bruce Mansfield coal-fired power plant is also within the immediate area. The Station was shutdown in October, 1982. Defueling operations began in 1983 and were completed by September, 1984. The Shippingport Station consists of a 275' x 60' fuel handling building containing the reactor containment chamber, the service building, the turbine building, the radioactive waste processing building, the administration building and other smaller support buildings. The Station has four coolant loops and most of the containment structures are located below grade. Structures owned by the U.S. Government including the fuel handling building, service building, contaminated equipment room, the boiler chambers, the radioactive waste processing building and the decontamination and laydown buildings will be dismantled and removed to 3 feet below grade. The area will then be filled with clean soil and graded. The turbine building, testing and training building and the administration building are owned by DLC and will remain

    As the first stage in the construction of the Paks Nuclear Power Station, two units of 440 MW(e) each will be built. They are operated with two coolant loops each. The reactor units are VVER 440 type water-moderated PWR type heterogeneous power reactors designed in the Soviet Union and manufactured in Czechoslovakia. Each unit operates two Soviet-made K-220-44 steam turbines and Hungarian-made generators of an effective output of 220 MW. The output of the transformer units - also of Hungarian made - is 270 MVA. The radiation protection system of the nuclear power station is described. Protection against system failures is accomplished by specially designed equipment and security measures especially within the primary circuit. Some data on the power station under construction are given. (R.P.)

    2013-03-01

    Full Text Available The last Hungarian repeat station survey was completed between October 2010 and February 2011. Declination, inclination and the total field were observed using one-axial DMI fluxgate magnetometer mounted on Zeiss20A theodolite and GSM 19 Overhauser magnetometer. The magnetic elements of the sites were reduced to the epoch of 2010.5 on the basis of the continuous recordings of Tihany Geophysical Observatory. In stations located far from the reference observatory, the observations were carried out in the morning and afternoon in order to decrease the effect of the distant temporal correction. To further increase the accuracy, on-site dIdD variometer has also been installed near the Aggtelek station, in the Baradla cave, during the survey of the easternmost sites. The paper presents the technical details and the results of our last campaign. The improvement of the accuracy of the temporal reduction by the use of the local variometer is also reported.

    The purpose of the invention is to create a process for undelayed automated detection and monitoring of accidents in the operation of nuclear power stations. According to the invention, this problem is solved by the relevant local measurements, such as radiation dose, components and type of radiation and additional relevant meteorological parameters being collected by means of wellknown data collection platforms, these being transmitted via transmission channels by means of satellites to suitable worldwide situated receiving stations on the ground, being processed there and being evaluated to recognise accidents. The local data collection platforms are used in the immediate vicinity of the nuclear power station. The use of aircraft, ships and balloons as data collection systems is also intended. (HWJ)

    Howles, L.R.

    1976-01-01

    For measurement of nuclear power station achievement against original purchase the usual gross output figures are of little value since the term loosely covers many different definitions. An authentically designed output figure has been established which relates to net design output plus house load at full load. Based on these figures both cumulative and moving annual load factors are measured, the latter measuring the achievement over the last year, thus showing trends with time. Calculations have been carried out for all nuclear stations in the Western World with 150 MW(e) gross design output and above. From these are shown: moving annual load factor indicating relative station achievements for all the plants; cumulative load factors from which return of investment can be calculated; average moving annual load factors for the four types of system Magnox, PWR, HWR, and BWR; and a relative comparison of achievement by country in a few cases.

    Hashimoto, H. [National Space Development Agency of Japan, Tokyo (Japan)

    1996-03-05

    This paper introduces the Japanese experiment module (JEM) in developing a space station. The JEM consists of systems of a pressurizing section, an exposure section, a pressurizing portion of a supply section, a manipulator and an exposure portion of the supply section. The pressurizing section circulates and controls air so that crews can perform experiments under pressurized environment. The exposure section is a part in which experiments are carried out under exposure environment. The supply section runs between a station and the ground, with required devices loaded on it. The manipulator performs attaching a payload for the exposure section and replaces experimental samples. The JEM undergoes a schedule of fabricating an engineering model, testing for a certification a prototype flight model, and putting the model on a flight. The pressurizing section, exposure section and manipulator are at the stage of system tests. Surveillance of the JEM and control of the experiments are carried out at the Tsukuba Space Center. The Center is composed of a space experiment building, a zero-gravity environment testing building, an astronaut training building, a space station operating building, and a space station testing building. 7 figs., 2 tabs.

    A personal hygiene system is currently under development for Space Station application that will provide capabilities equivalent to those found on earth. This paper addresses the study approach for specifying both primary and contingency personal hygiene systems and provisions for specified growth. Topics covered are system definition and subsystem descriptions. Subsystem interfaces are explored to determine which concurrent NASA study efforts must be monitored during future design phases to stay up-to-date on critical Space Station parameters. A design concept for a three (3) compartment personal hygiene facility is included as a baseline for planned test and verification activities.

    Pedersen, K.

    1986-01-01

    In assessing the prospects of the NASA Space Station program, it is important to take account of the long term perspective embodied in the proposal; its international participants are seen as entering a complex web of developmental and operational interdependence of indefinite duration. It is noted to be rather unclear, however, to what extent this is contemplated by such potential partners as the ESA, which has its own program goals. These competing hopes for eventual autonomy in space station operations will have considerable economic, technological, and political consequences extending well into the next century.

    Full Text Available This house is situated on a site whose slope has been exploited in order to arrange the two levels of the building according to the following distribution. Ground floor: boiler room, operator's quarters with bathroom, garage and stables. Main floor: this contains the main living space and has two wings, whose internal arrangement is as follows. On the right, the living room, dining room and kitchen; on the left a family room, six bedrooms and services. The rough simplicity of the Hooper house is reminiscent of the proud and solid tradition of the older buildings of this district, yet in spite of its apparent austerity it conveys a peculiarly pleasant and enjoyable atmosphere. Breuer's style becomes evidently manifest in this design through his powerful and original manner in the treatment of external forms, care and appropriateness of the building medium, elegance and carefully ellaborated distribution.Está ubicada en un terreno, cuyo desnivel ha sido aprovechado para organizar la edificación en dos plantas: La inferior aloja: el cuarto de calefacción, habitación del mecánico con baño, garaje y establos. La superior contiene las áreas de vivir, y presenta dos alas: la derecha, ocupada por el estar, comedor y cocina; la izquierda, constituida por la sala familiar, seis dormitorios y servicios. La ruda simplicidad de la casa Hooper le confiere la arrogante y sólida tradición de las casas del pasado —de la región— y determina sea una casa, en la, que, a pesar de una aparente austeridad, se disfruta de una atmósfera peculiar agradable. El estilo de Breuer se manifiesta aquí de manera inconfundible con su impronta, poderosa y única, en cuanto a tratamiento de exteriores, cuidado y propiedad de materiales empleados, elegancia y estudiada distribución.

  16. Single-Station Sigma for the Iranian Strong Motion Stations

    In development of ground motion prediction equations (GMPEs), the residuals are assumed to have a log-normal distribution with a zero mean and a standard deviation, designated as sigma. Sigma has significant effect on evaluation of seismic hazard for designing important infrastructures such as nuclear power plants and dams. Both aleatory and epistemic uncertainties are involved in the sigma parameter. However, ground-motion observations over long time periods are not available at specific sites and the GMPEs have been derived using observed data from multiple sites for a small number of well-recorded earthquakes. Therefore, sigma is dominantly related to the statistics of the spatial variability of ground motion instead of temporal variability at a single point (ergodic assumption). The main purpose of this study is to reduce the variability of the residuals so as to handle it as epistemic uncertainty. In this regard, it is tried to partially apply the non-ergodic assumption by removing repeatable site effects from total variability of six GMPEs driven from the local, Europe-Middle East and worldwide data. For this purpose, we used 1837 acceleration time histories from 374 shallow earthquakes with moment magnitudes ranging from M w 4.0 to 7.3 recorded at 370 stations with at least two recordings per station. According to estimated single-station sigma for the Iranian strong motion stations, the ratio of event-corrected single-station standard deviation ( Φ ss) to within-event standard deviation ( Φ) is about 0.75. In other words, removing the ergodic assumption on site response resulted in 25% reduction of the within-event standard deviation that reduced the total standard deviation by about 15%.

    Giudici, R.J.

    1985-01-01

    Issues governing the selection of power systems for long-term manned Space Stations intended solely for earth orbital missions are covered briefly, drawing on trade study results from both in-house and contracted studies that have been conducted over nearly two decades. An involvement, from the Program Development Office at MSFC, with current Space Station concepts began in late 1982 with the NASA-wide Systems Definition Working Group and continued throughout 1984 in support of various planning activities. The premise for this discussion is that, within the confines of the current Space Station concept, there is good reason to consider photovoltaic power systems to be a venerable technology option for both the initial 75 kW and 300 kW (or much greater) growth stations. The issue of large physical size required by photovoltaic power systems is presented considering mass, atmospheric drag, launch packaging and power transmission voltage as being possible practicality limitations. The validity of searching for a cross-over point necessitating the introduction of solar thermal or nuclear power system options as enabling technologies is considered with reference to programs ranging from the 4.8 kW Skylab to the 9.5 gW Space Power Satellite

    2011-04-01

    In the early phase of the emergence of influenza A (H1N1) 2009 abroad, quarantine detention measures based on exposure assessment of infected persons at airports were enacted in Japan. Detention, while being a step needed to protect safety and health of citizens, restricts healthy individuals' activities for several days until they can be confirmed to be not infected. Thus, the number of persons detained must be minimized in the interest of human rights. In this study, we reviewed factors to be considered in decision-making to carry out optimal detention in the early phase of emergence of a novel influenza virus in the future. We reviewed manuscripts on contagiousness of influenza, cases of infections in public transportation such as airplanes, and the effectiveness of detention, and interviewed persons who were involved in detentions in the early phase of the influenza A(H1N1) 2009 pandemic. When a decision is made about detention, it is essential to assess the necessity of detention, the measures for minimizing the scope of individuals to be detained, the measures for ensuring the human rights of individuals affected, and possible means to substitute for detention. Assessment of the necessity of detention should cover the following: (1) whether or not the novel influenza is a sufficiently severe threat to public health to justify detention; (2) whether or not detention at a given point of time can delay the beginning of a domestic epidemic; and (3) who is responsible and how revision of the once decided detentions should be made. Regarding measures for minimizing the scope of individuals to be detained, discussions are needed as to: (1) giving advice to the nation to refrain from getting aboard an airplane when aware of flu-like symptoms so that exposure of people to infected individuals may be avoided; and (2) whether or not selection of individuals to be detained is going to be made, taking into account the level of exposure to infected individuals. To ensure

  8. Irradiation as a quarantine treatment against the invader fruit fly (Bactrocera Invadens, Drew) in mangoes (Mangifera Indica L,)

    International Nuclear Information System (INIS)

    Odai, B.T.

    2010-06-01

    The detection of the African invader fly, Bactrocera invadens Drew, Tsuruta and White, in Ghana has led to limitations in the export of mango fruits from Ghana to other countries. The limitations ranging from increased control costs to outright rejection of exports has necessitated a study in the area of quarantine treatment. A study was conducted to ascertain the effectiveness of gamma radiation for control of Bactrocera invadens in fruit destined for export. Pupae were obtained from the incubation of mango fruits collected from various locations. Adults were reared and infestation levels were determined after fruits were exposed to 5, 10, 20 females in different cages. Late instar larvae in fruits were irradiated at 15, 25, 35, 45, 50, 60 and 75 Gy to determine an effective dose for B. invadens. The mortality of the fly was determined at the various doses to obtain a probit 9 figure of 68.06 Gy (rounded to 70 Gy). The confirmatory test for 3050 larvae endorsed the effective dose as the probit 9 dose. Non-infested mature green export grade mango fruits were irradiated with 0, 70 and 150 Gy to determine its effect on ascorbic acid and total acidity content, sweetness, colour, juiciness, sourness, aroma and firmness of the mango fruits. Ascorbic acid and total acidity were not irradiation dependent. Varietal differences (p 0.05) by irradiation. Varietal differences did not affect the acceptability of the sweetness, sourness and colour of the fruits (p>0.05). Storage days significantly affected (p<0.05) the acceptability of all the sensory attributes. (au)

    1990-01-01

    An ergonomic integration of controls, displays, and associated interfaces with an operator, whose body geometry and dynamics may be altered by the state of weightlessness, is noted to rank in importance with the optimal positioning of controls relative to the layout and architecture of 'body-ported' work/control stations applicable to the NASA Space Station Freedom. A long-term solution to this complex design problem is envisioned to encompass the following features: multiple imaging, virtual optics, screen displays controlled by a keyboard ergonomically designed for weightlessness, cursor control, a CCTV camera, and a hand-controller featuring 'no-grip' vernier/tactile positioning. This controller frees all fingers for multiple-switch actuations, while retaining index/register determination with the hand controller. A single architectural point attachment/restraint may be used which requires no residual muscle tension in either brief or prolonged operation.

    The country-of-origin labeling (COOL) law requires United States grocers to indicate the origin and procurement method (farm-raised or wild-caught) for seafood. This study explored the presentation of COOL on fresh, frozen, packaged, and unpackaged seafood in Baltimore City grocery stores. Eight stores were visited bi-monthly to photograph seafood labels, and circulars were collected weekly from fourteen stores over three months. Ninety-six percent of products were labeled correctly. Forty-eight percent of advertisements included COOL. While in-store labels did not highlight COOL, advertising featured references to domestic and wild-caught seafood, signaling to customers that these are high-value product qualities.

    ELECTRICITE DE FRANCE currently operates 51 generating stations with 900 and 1300 MW Pressurized Water Reactors while, only 15 years ago, France possessed only a very small number of such stations. It was therefore vital to set up a major training organization to produce staff capable of starting, controlling and maintaining these facilities with a constant eye to improving quality and safety. Operator and maintenance staff training is based on highly-structured training plans designed to match both the post to be filled and the qualifications possessed by the person who is to fill it. It was essential to set up suitable high-performance training resources to handle this fast growth in staff. These resources are constantly being developed and allow EDF to make steady progress in a large number of areas, varying from the effects of human factors to the procedures to be followed during an accident

    The findings from the Skylab missions are discussed as they relate to the operations planning of future space stations such as Spacelab and the proposed Space Operations Center. Following a brief description of the Skylab spacecraft, the significance of the mission as a demonstration of the possibility of effecting emergency repairs in space is pointed out. Specific recommendations made by Skylab personnel concerning capabilities for future in-flight maintenance are presented relating to the areas of spacecraft design criteria, tool selection and spares carried. Attention is then given to relevant physiological findings, and to habitability considerations in the areas of sleep arrangements, hygiene, waste management, clothing, and food. The issue of contamination control is examined in detail as a potential major system to be integrated into future design criteria. The importance of the Skylab results to the designers of future space stations is emphasized.

    The optimized conceptual engineering design of a space station tethered elevator is presented. The tethered elevator is an unmanned, mobile structure which operates on a ten-kilometer tether spanning the distance between Space Station Freedom and a platform. Its capabilities include providing access to residual gravity levels, remote servicing, and transportation to any point along a tether. The report discusses the potential uses, parameters, and evolution of the spacecraft design. Emphasis is placed on the elevator's structural configuration and three major subsystem designs. First, the design of elevator robotics used to aid in elevator operations and tethered experimentation is presented. Second, the design of drive mechanisms used to propel the vehicle is discussed. Third, the design of an onboard self-sufficient power generation and transmission system is addressed.

    1990-01-01

    The feasibility of directly converting solar energy for crew water heating on the Space Station Freedom (SSF) and other human-tended missions such as a geosynchronous space station, lunar base, or Mars spacecraft was investigated. Computer codes were developed to model the systems, and a proof-of-concept thermal vacuum test was conducted to evaluate system performance in an environment simulating the SSF. The results indicate that a solar water heater is feasible. It could provide up to 100 percent of the design heating load without a significant configuration change to the SSF or other missions. The solar heater system requires only 15 percent of the electricity that an all-electric system on the SSF would require. This allows a reduction in the solar array or a surplus of electricity for onboard experiments.

    In the United Kingdom the Electricity Boards, the United Kingdom Atomic Energy Authority (UKAEA) and BNFL cooperate on all matters relating to the decommissioning of nuclear plant. The Central Electricity Generating Board's (CEGB) policy endorses the continuing need for nuclear power, the principle of reusing existing sites where possible and the building up of sufficient funds during the operating life of a nuclear power station to meet the cost of its complete clearance in the future. The safety of the plant is the responsibility of the licensee even in the decommissioning phase. The CEGB has carried out decommissioning studies on Magnox stations in general and Bradwell and Berkeley in particular. It has also been involved in the UKAEA Windscale AGR decommissioning programme. The options as to which stage to decommission to are considered. Methods, costs and waste management are also considered. (U.K.)

  19. Stage measurement at gaging stations

    Science.gov (United States)

    Sauer, Vernon B.; Turnipseed, D. Phil

    2010-01-01

    Stream and reservoir stage are critical parameters in the computation of stream discharge and reservoir volume, respectively. In addition, a record of stream stage is useful in the design of structures that may be affected by stream elevation, as well as for the planning for various uses of flood plains. This report describes equipment and methodology for the observation, sensing, and recording of stage in streams and reservoirs. Although the U.S. Geological Survey (USGS) still uses the traditional, basic stilling-well float system as a predominant gaging station, modern electronic stage sensors and water-level recorders are now commonly used. Bubble gages coupled with nonsubmersible pressure transducers eliminate the need for stilling wells. Submersible pressure transducers have become common in use for the measurement of stage in both rivers and lakes. Furthermore, noncontact methods, such as radar, acoustic, and laser methods of sensing water levels, are being developed and tested, and in the case of radar, are commonly used for the measurement of stage. This report describes commonly used gaging-station structures, as well as the design and operation of gaging stations. Almost all of the equipment and instruments described in this report will meet the accuracy standard set by the USGS Office of Surface Water (OSW) for the measurement of stage for most applications, which is ±0.01 foot (ft) or 0.2 percent of the effective stage. Several telemetry systems are used to transmit stage data from the gaging station to the office, although satellite telemetry has become the standard. These telemetry systems provide near real-time stage data, as well as other information that alerts the hydrographer to extreme or abnormal events, and instrument malfunctions.

    Health data for free-living eastern box turtles (Terrapene carolina carolina) at the Maryland Zoo in Baltimore were analyzed. One hundred and eighteen turtles were captured on or near zoo grounds over the course of 15 yr (1996-2011), with recapture of many individuals leading to 208 total evaluations. Of the 118 individuals, 61 were male, 50 were female, and 7 were of undetermined sex. Of the 208 captures, 188 were healthy, and 20 were sick or injured. Complete health evaluations were performed on 30 turtles with physical examination records, complete blood counts (CBCs), and plasma biochemistry profiles. Eight animals were sampled more than once, yielding 40 total samples for complete health evaluations of these 30 individuals. The 40 samples were divided into healthy (N=29) and sick (N=11) groups based on clinical findings on physical examination. Samples from healthy animals were further divided into male (N=17) and female (N= 12) groups. CBC and biochemistry profile parameters were compared between sick and healthy groups and between healthy males and females. Sick turtles had lower albumin, globulin, total protein (TP), calcium, phosphorous, sodium, and potassium than healthy animals. Sick turtles also had higher heterophil to lymphocyte ratios. Healthy female turtles had higher leukocyte count, eosinophil count, total solids, TP, globulin, cholesterol, calcium, and phosphorous than healthy males. Banked plasma from all 40 samples was tested for antibodies to Mycoplasma agassizii and Mycoplasma testudineum via enzyme-linked immunosorbent assay. One sample from a clinically healthy female was antibody positive for M. agassizii; none were positive for M. testudineum. This study provides descriptive health data for eastern box turtles and CBC and biochemistry profile information for T. carolina carolina at and near the Maryland Zoo in Baltimore. It also reports low serologic evidence of exposure to mycoplasmosis.

  3. Pumps for nuclear power stations

    International Nuclear Information System (INIS)

    Ogura, Shiro

    1979-01-01

    16 nuclear power plants are in commercial operation in Japan, and nuclear power generation holds the most important position among various substitute energies. Hereafter also, it is expected that the construction of nuclear power stations will continue because other advantageous energy sources are not found. In this paper, the outline of the pumps used for BWR plants is described. Nuclear power stations tend to be large scale to reduce the construction cost per unit power output, therefore the pumps used are those of large capacity. The conditions to be taken in consideration are high temperature, high pressure, radioactive fluids, high reliability, hydrodynamic performances, aseismatic design, relevant laws and regulations, and quality assurance. Pumps are used for reactor recirculation system, control rod driving hydraulic system, boric acid solution injecting system, reactor coolant purifying system, fuel pool cooling and purifying system, residual heat removing system, low pressure and high pressure core spraying systems, and reactor isolation cooling system, for condensate, feed water, drain and circulating water systems of turbines, for fresh water, sea water, make-up water and fire fighting services, and for radioactive waste treating system. The problems of the pumps used for nuclear power stations are described, for example, the requirement of high reliability, the measures to radioactivity and the aseismatic design. (Kako, I.)

  4. Optimization of station battery replacement

    International Nuclear Information System (INIS)

    Jancauskas, J.R.; Shook, D.A.

    1994-01-01

    During a loss of ac power at a nuclear generating station (including diesel generators), batteries provide the source of power which is required to operate safety-related components. Because traditional lead-acid batteries have a qualified life of 20 years, the batteries must be replaced a minimum of once during a station's lifetime, twice if license extension is pursued, and more often depending on actual in-service dates and the results of surveillance tests. Replacement of batteries often occurs prior to 20 years as a result of systems changes caused by factors such as Station Blackout Regulations, control system upgrades, incremental load growth, and changes in the operating times of existing equipment. Many of these replacement decisions are based on the predictive capabilities of manual design basis calculations. The inherent conservatism of manual calculations may result in battery replacements occurring before actually required. Computerized analysis of batteries can aid in optimizing the timing of replacements as well as in interpreting service test data. Computerized analysis also provides large benefits in maintaining the as-configured load profile and corresponding design margins, while also providing the capability of quickly analyze proposed modifications and response to internal and external audits

  5. CNG Fuelling Stations Design Philosophy

    International Nuclear Information System (INIS)

    Radwan, H.

    2004-01-01

    I. Overview (a) Compressed Natural Gas - CNG:- Natural Gas, as an alternative fuel for vehicles, is supplied from the Natural Gas Distribution Network to the CNG fuelling stations to be compressed to 250 bars. It is then dispensed, to be stored on board of the vehicle at about 200 bars in a cylinder installed in the rear, under carriage, or on top of the vehicle. When the Natural Gas is required by the engine, it leaves the cylinder traveling through a high pressure pipe to a high pressure regulator, where the pressure is reduced close to atmospheric pressure, through a specially designed mixer, where it is properly mixed with air. The mixture then flows into the engine's combustion chamber, and is ignited to create the power required to drive the vehicle. (b) CNG Fuelling Stations General Description: as Supply and Metering The incoming gas supply and metering installation primarily depend on the pressure and flow demands of the gas compressor. Natural Gas Compressor In general, gas compressors for natural gas filling stations have relatively low flow rates

    2006-01-01

    The working report for the spent fuel canister docking station presents a design for the operation and structure of the docking equipment located in the fuel handling cell for the spent fuel in the encapsulation plant. The report contains a description of the basic requirements for the docking station equipment and their implementation, the operation of the equipment, maintenance and a cost estimate. In the designing of the equipment all the problems related with the operation have been solved at the level of principle, nevertheless, detailed designing and the selection of final components have not yet been carried out. In case of defects and failures, solutions have been considered for postulated problems, and furthermore, the entire equipment was gone through by the means of systematic risk analysis (PFMEA). During the docking station designing we came across with needs to influence the structure of the actual disposal canister for spent nuclear fuel, too. Proposed changes for the structure of the steel lid fastening screw were included in the report. The report also contains a description of installation with the fuel handling cell structures. The purpose of the docking station for the fuel handling cell is to position and to seal the disposal canister for spent nuclear fuel into a penetration located on the cell floor and to provide suitable means for executing the loading of the disposal canister and the changing of atmosphere. The designed docking station consists of a docking ring, a covering hatch, a protective cone and an atmosphere-changing cap as well as the vacuum technology pertaining to the changing of atmosphere and the inert gas system. As far as the solutions are concerned, we have arrived at rather simple structures and most of the actuators of the system are situated outside of the actual fuel handling cell. When necessary, the equipment can also be used for the dismantling of a faulty disposal canister, cut from its upper end by machining. The

    Work station layout in the ideal way has been made. The dimension of the work station is 9.4 m x 7.1 m. The workers to be stationed should feel comfort. This can be done by honoring the dimensions and the sum of the tools that should be stationed and also the free space that should be mention between the tools as state in EPRI, NP-2411. (author)

    Full Text Available The model of pavilion lazaretto was built above the scientific basis established during the hospital reform process held in France on the lasts decades of Eighteenth Century. The morphological solutions adopted for the new quarantine taxonomy has not been given by the example borrowed by the new typology of hospital as resulted in this discussion, but by existing quarantine and detention facilities in general. In this paper we will analyse all factors that have influenced in the configuration of this model of lazarettos.

    El modelo de lazareto pabellonario se configuró a partir de las bases científicas establecidas durante el proceso de reforma hospitalaria acaecido en Francia en el último tercio del setecientos. La adopción de soluciones que dieran forma a la nueva tipología cuarentenaria no vino dada precisamente por el ejemplo prestado por los nuevos tipos de hospital resultantes de este debate sino por el de otras instalaciones de cuarentena y, en general, de encierro, ya existentes. En este artículo se analizarán todos los factores que influyeron en la configuración de este modelo de lazaretos.

  13. Quarantine as a public health measure against an emerging infectious disease: syphilis in Zurich at the dawn of the modern era (1496–1585

    Full Text Available Syphilis is considered as one of the most devastating sexually transmitted diseases in human history. Based on historical records, the (German for spread through Europe after 1495 and shared symptoms with what we know today as syphilis. Many cities took measures to protect their population. Here, transliterations of archival documents from the 15 and 16 century (provided in the appendix are used to trace the steps taken by the governing authorities in Zurich to deal with this emerging infectious disease. One of the central measures taken by the city was to establish a quarantine facility referred to as the The city doctors, including the well-known physician and naturalist Conrad Gessner, oversaw the obligatory quarantine and treatment of patients with symptoms. Treatment could range from better nutrition, herbal remedies and skin ointments to aggressive heat therapy and “smoking”. Furthermore, the affliction was suspected as a sexually acquired disease, hence prostitutes and infected foreigners were extradited from the city. Meanwhile, the church used its social influence to promote a more “Christian” behavior. In several respects, the public health measures taken in the 16 century against a new and menacing epidemic do not diverge in their basic rationale from approaches used during the 20 century and today.

    The objective of this study was to evaluate the fruit fly infestation on coffee and citrus, and also to determine gamma radiation doses for immature stages of Ceratitis capitata and Anastrepha fraterculus, in order to satisfy quarantine regulations. Coffee arabica varieties Icatu Vermelho, Catuai Amarelo, Mundo Novo and Sarchimor showed the highest infestation indices (pupa/berry): 0.53; 0,41; 0.33 and 0.36. respectively Icatu Vermelho and Catuai Vermelho showed the highest values of pupa/berry weight (0.49 and 0.39, respectively), and Robusta (Coffea canephora) presented the lowest index (0.01). The following fruit flies were found in coffee berries: C. capitata (76.6%) Anastrepha spp. (7.4%) and Lonchaeidae (17.0%). In area near coffee plantation, fruit fly infestation indices in sweet oranges were of 4.77 larvae/kg and 0.55 larva/fruit. The infestation indices for sweet orange, collected from five regions of the State of Sao Paulo ranged from 0.73 to 7.60 pupa/kg and 0.12 to 1.27 pupa/fruit. The same species of fruit flies were found in oranges. In the case of C. capitata eggs with 24-48 hours old, 20 Gy prevented completely adult emergence (artificial diet and orange). No emergence of adult occurred when C. capitata larvae of third instar were irradiated at 20 Gy in their rearing medium. But at 25 Gy, the number of adults was reduced by 54% and 97% from larval infestation in oranges and grapefruit, respectively. A dose of 30 Gy was required to prevent medfly emergence from third instar larvae in grapefruit. A dose of 15 Gy was required for third instar, to prevent adult emergence of A. fraterculus. No adult emerged from C third instar, to prevent adult emergence of A. fraterculus. No adult emerged from C capitata pre-pupa irradiated at 30 Gy. One medfly adult emerged from pupa (3-4 days after pupating) irradiated at 120 Gy. At the same dose, sixteen A. fraterculus adults emergency from irradiated pupa with 5-6 days old. (author)
