    Baltimore is the largest city in Maryland and one of the busiest ports in the United States. Its economy focuses on research and development, especially in the areas of aquaculture, pharmaceuticals, and medical supplies and services. Before European settlement, the site of Baltimore was inhabited by Native Americans of the Susquehannock tribe. The town was founded in 1729 and named for the barons Baltimore, the British founders of the Maryland Colony. This ASTER image of Baltimore was acquired on April 4, 2000, covers an area of 17 by 20 km, and is located at 39.3 degrees north latitude and 76.7 degrees west longitude.

    Baltimore`s Resource Recovery, an intermediate glass cullet processing facility, is utilizing light-based optical sorting technology to produce a cleaner end product. Resource Recovery, Inc. has found that keeping things simple at its year-and-a-half-old location in Baltimore is making practical economic sense--and dollars and cents. The company would rather put its money into hardware; there`s nothing particularly fancy about the operation. Anyone can crush glass, but the trick to a glass recovery operation is to add value to the cullet by cleaning it up. Intermediate cullet processor Resource Recovery, which buys its glass primarily from materials recovery facilities (MRFs) in the surrounding Baltimore-Washington, DC, area, has found that by utilizing the optical-sensing glass separation system, it cannot only separate glass by color, but can also lower the level of ceramic and other contaminants in its end product to virtually nil.

    2015-01-01

    As intensive vegetable cultivation is rapidly expanding in China and elsewhere worldwide, its environmental consequences on nitrous oxide (N(2)O) and nitric oxide (NO) emissions deserve attention. We measured N(2)O and NO fluxes simultaneously for a full year from Chinese subtropical vegetable fields. Clearly, both N(2)O and NO emissions varied greatly in different vegetable crop seasons within a year, highlighting the importance of whole-year measurement for achieving temporally accurate annual direct emission factors. A revised "hole-in-the-pipe" model well described quantitative relationships between N(2)O plus NO fluxes and soil-specific conditions. Annual background N(2)O and NO emissions were 0.73-5.0 and 0.26-0.56 kg N ha(-1) yr(-1), respectively, for the vegetable cultivations. The farmers' fertilization practice increased N(2)O and NO emissions. Annual direct emission factors for greenhouse and conventional vegetable fields, respectively, were 1.1% and 1.9% for N(2)O, and 0.36% and 0.32% for NO, indicating there is a need to consider a differentiation of emission factors for managed vegetable cultivations.

  4. Comparing Baltimore and Phoenix

    NASA Technical Reports Server (NTRS)

    2002-01-01

    The 'zoom lens' aboard NASA's Terra spacecraft acquired these views of two U.S. cities: Baltimore, Maryland (left), and Phoenix, Arizona (right). Acquired by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER), red in these false-colored images indicates vegetation. The turquoise pixels show paved areas while darker greens and browns show bare earth and rock surfaces. The 'true' constructed nature of these cities is not easy to see. Ecologists now accept human beings and our activities as a significant factor in studying the Earth's ecology. ASTER data are being used to better understand urban ecology, in particular how humans build their cities and affect the surrounding environment. At the recent American Geophysical Union (AGU) meeting in Boston, Will Stefanov of Arizona State University presented the first set of ASTER images of the urban 'skeletons' of the amount of built structures in twelve cities around the world. He also discussed the Urban Environmental Monitoring project, in which scientists are examining 100 urban centers to look for common features (or lack of them) in global city structure as well as to monitor their changes over time.

  5. Initiating population education in Baltimore.

    PubMed

    Cochran, C S; Mccrea, L C

    1974-01-01

    At a 3-day workshop in population education for 50 secondary school teachers, 4 members of the Baltimore City Public School system were appointed with 4 members of Planned Parenthood Association of Maryland to deal with the inherent difficulties of bringing population awareness to city children, many of whom in Baltimore are both poor and black. This group believed that it was essential that racial sensitivities, both black and white, be explored in a realistic and humane manner. After considerable soul-searching, it was decided that the approach would be to talk about the city of Baltimore and then demonstrate that Baltimore and its problems represented a microcosm of the world. A pilot institute for 30 selected Baltimore City public school teachers was held in June 1971. The participants of this institute felt that population education should be included in the public school curriculum, and materials to implement this were requested. On the basis of this experiment, the Rockefeller Foundation gave Planned Parenthood Association of Maryland a grant to continue its work with the Baltimore City school system. Nine 3-day Urban Life Population Education Institutes for 30 teachers each were held during school hours in the 1973-1974 school year. All teachers in the system could apply to attend. During the summer of 1973 nine creative and imaginative classroom teachers who had attended an institute were selected to develop curriculum materials. They adopted 6 basic concepts covering the overall view down to the individual level. With the aid of another grant from the Rockefeller Foundation, the materials developed will be piloted in the Baltimore schools during the 1973-1974 session. 10 more institutes for 300 members of the school system will be held during the 1973-1974 school year.

Modification 2 of this permit authorizes ODFW to take adults for spawning and the production and release of smolts for the Captive and Conventional broodstock programs. This report satisfies the requirement that an annual report be submitted. Herein we report on activities conducted and provide cursory data analyses for the Grande Ronde spring chinook salmon Captive and Conventional broodstock projects from 1 January-31 December 2002. The Grande Ronde Basin Spring Chinook Salmon Captive Broodstock Project is designed to rapidly increase numbers of salmon in stocks that are in imminent danger of extirpation. Parr are captured in Catherine Creek, upper Grande Ronde River and Lostine River and reared to adulthood in captivity. Upon maturation, they are spawned (within stocks) and their progeny reared to smoltification before being released into the natal stream of their parents. This program is co-managed by ODFW, National Marine Fisheries Service, the Nez Perce Tribe and Confederated Tribes of the Umatilla Indian Reservation.

  14. Baltimore Air Toxics Study (BATS)

    SciTech Connect

    Sullivan, D.A.

    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.

    BPA Fish and Wildlife Program Project Number 1998-01-001 provides funding for the Grande Ronde Basin Spring Chinook Salmon Captive Broodstock Program. This report satisfies the requirement that an annual report be submitted for FY 2003. The Grande Ronde Basin Spring Chinook Salmon Captive Broodstock Project is designed to rapidly increase numbers of salmon in stocks that are in imminent danger of extirpation. Parr are captured in Catherine Creek, upper Grande Ronde River and Lostine River and reared to adulthood in captivity. Upon maturation, these fish are spawned (within stocks) and their progeny reared to smoltification before being released into the natal stream of their parents. This program is co-managed by ODFW, National Marine Fisheries Service, Nez Perce Tribe and Confederated Tribes of the Umatilla Indian Reservation. This report covers activities conducted and provides data analyses for the Grande Ronde Spring Chinook Salmon Captive broodstock Program from 1 January--31 December 2003. Since the fiscal year ends in the middle of the spawning period, an annual report based on calendar year is more logical. This document is the FY 2003 annual report. Detailed information on historic and present population status, project background, goals and objectives, significance to regional programs and relationships to other programs, methods and previous results are available in the 1995-2002 Project Status Report (Hoffnagle et al 2003).

    An AGATE Concepts Demonstration was conducted at the Annual National Air Transportation Association (NATA) Convention in 1997. Following, a 5-minute introductory briefing, an interactive simulation of a single-pilot, single-engine aircraft was conducted. The participant was able to take off, fly a brief enroute segment, fly a Global Positioning System (GPS) approach and landing, and repeat the approach and landing segment. The participant was provided an advanced 'highway-in-the-sky' presentation on both a simulated head-up display and on a large LCD head-down display to follow throughout the flight. A single-lever power control and display concept was also provided for control of the engine throughout the flight. A second head-down, multifunction display in the instrument panel provided a moving map display for navigation purposes and monitoring of the status of the aircraft's systems.

A single-lever power control and display concept was also provided for control of the engine throughout the flight. A second head-down, multifunction display in the instrument panel provided a moving map display for navigation purposes and monitoring of the status of the aircraft's systems. An estimated 100 people observed or participated in the demonstration, and 68 surveys were collected. The pilot ratings of the participants ranged from student to Air Transport Rating with an average of 6089 hours total flight time. The overwhelming response was that technologies that simplify piloting tasks are enthusiastically welcomed by pilots of all experience levels. The increase in situation awareness and use of the head-up display were universally accepted and lauded as steps in the right direction.

  17. Hydraulic Geometry Characteristics of Continuous-Record Streamflow-Gaging Stations on Four Urban Watersheds Along the Main Stem of Gwynns Falls, Baltimore County and Baltimore City, Maryland

    USGS Publications Warehouse

    Doheny, Edward J.; Fisher, Gary T.

    2007-01-01

    Four continuous-record streamflow-gaging stations are currently being operated by the U.S. Geological Survey on the main stem of Gwynns Falls in western Baltimore County and Baltimore City, Maryland. The four streamflow-gaging stations drain urban or suburban watersheds with significantly different drainage areas. In addition to providing continuous- record discharge data at these four locations, operation of these stations also provides a long-term record of channel geometry variables such as cross-sectional area, channel width, mean channel depth, and mean velocity that are obtained from physical measurement of the discharge at a variety of flow conditions. Hydraulic geometry analyses were performed using discharge-measurement data from four continuous-record streamflow-gaging stations on the main stem of Gwynns Falls. Simple linear regression was used to develop relations that (1) quantify changes in cross-sectional area, channel width, mean channel depth, and mean velocity with changes in discharge at each station, and (2) quantify changes in these variables in the Gwynns Falls watershed with changes in drainage area and annual mean discharge. Results of the hydraulic geometry analyses indicated that mean velocity is more responsive to changes in discharge than channel width and mean channel depth for all four streamflow-gaging stations on the main stem of Gwynns Falls. For the two largest and most developed watersheds, on Gwynns Falls at Villa Nova, and Gwynns Falls at Washington Boulevard at Baltimore, the slope of the regression lines, or hydraulic exponents, indicated that mean velocity was more responsive to changes in discharge than any of the other hydraulic variables that were analyzed. This was true even when considering changes in cross-sectional area with discharge, which incorporates the combined effects of channel width and mean channel depth. A comparison of hydraulic exponents for Gwynns Falls to average values from previous work indicated that

  20. Solar ultraviolet-B radiation in urban environments: Baltimore, Maryland

    NASA Astrophysics Data System (ADS)

    Heisler, Gordon M.; Grant, Richard H.; Gao, Wei; Slusser, James R.; Ehrlich, Corinne

    2003-06-01

    Ultraviolet radiation from the sun, especially the UVB (280 to 320 nm), has important roles in urban ecosystems, including effects on human health. Broadband UVB radiation is being continuously monitored in the city of Baltimore, MD as part of a long-term ecological research program, the Baltimore Ecosystem Study. This paper compares above-canopy broadband UVB irradiance at the Baltimore station to broadband UVB irradiance at a more-rural station 64 km SE (at Wye Research Center in Queenstown, MD) and a station characterized as suburban within the Baltimore-Washington metropolitan area, 42 km SW (at Beltsville Agricultural Experiment Station). The Baltimore data are from the initial 14 months of measurements there. The solar radiation monitoring station in Baltimore is located on a 33-m-tall building on a high point with no significant obstructions to sky view. The broadband instruments, all of which were provided by the USDA UVB Monitoring and Research Program, were calibrated in the same facility, the NOAA Central UV Calibration Facility in Colorado. In general, UVB irradiances at the three sites were similar. Over all conditions, Baltimore and the suburban site measured 3.4% less irradiance than the rural site. This difference is within the anticipated +/-3% calibration uncertainty of the broadband pyranometers. On the 59 days with cloud-free conditions at all three sites, the average differences between measured UVB at the three sites was even smaller; Baltimore measured 1.2% less irradiance than the rural site. On the clear days, differences between total daily irradiance and the trend of daily irradiance through the year were clearly related to total column ozone as indicated by the EPTOMS satellite. High aerosol optical thickness strongly reduced daily UVB dose; whereas [SO2] had no influence. Surface O3 increased with increasing UVB dose when [NO2] exceeded 10 ppb.

  1. INCARCERATION AND INJECTION DRUG USE IN BALTIMORE, MARYLAND

    AIMS There is limited longitudinal research examining incarceration and subsequent changes in drug use among people who inject drugs (PWID) in the US. 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. DESIGN 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. SETTING Baltimore, Maryland, USA PARTICIPANTS A total of 3,245 participants with 48,738 study visits were included. Participants enrolled from 1988 through 2012 with a median of 13 follow-up visits per participant (interquartile range: 7–25). MEASUREMENTS Incarcerations were defined as any self-reported jail or prison stays in the previous six months that were 7 days or longer. The primary outcome was defined as any self-reported injection drug use in the previous six months. FINDINGS At baseline, 29% were female, 90% African-American, and 33% HIV-positive. Fifty-seven percent of participants experienced at least one incarceration episode. After adjusting for confounders, there was a positive association between incarceration and subsequent injection drug use (AOR=1.48, 95% 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). CONCLUSIONS In the United States, incarceration of people who had previously stopped injecting drugs appears to be associated with an increased risk of subsequent injecting. PMID:25845621

    New well data and a new gravity model across the southern end of Baltimore Canyon Trough provide a more complete history of the basin's tectonic evolution and deep crustal structure than was previously known. The basin, which formed during the separation of North America from Africa, narrows and shallows along strike, as basement depth decreases from about 18 km (59,000 ft) in the north near New York to about 4-6 km (13,123-19,685 ft) in the south near Cape Hatteras. Previous analysis of the Continental Offshore Stratigraphic Test (COST) B2 and B3 wells using backstripping techniques showed a seaward increase in the amount of stretching during the basin's formation. The new biostratigraphic and paleoenvironmental interpretations are from the USGS Island Beach well 1 just landward of the hinge zone in the basin. This well, along with the COST B2 and B3 data, provides a sampling of the sedimentary sections overlying continental, transitional (rift-stage), and oceanic crust. The subsidence histories derived from these data give a cross-sectional view of the basin's evolution. A gravity model of the southern end of the basin, along USGS multichannel seismic line 28, primarily analyzes a 60-mgal shelfedge anomaly. This anomaly reflects the change in bathymetry and more important a change toward the continent in underlying crustal thickness from typical oceanic to thinned continental crust. The crustal thinning is compared to the broad thinning zone to the north. Well-defined rift structures on the landward edge of the basin are modeled as rift grabens near the hinge zone.

  5. An experiment in contingent valuation: Willingness to pay for stormwater management. [Homeowners in Baltimore County

    The contingent valuation (CV) method is a technique used frequently in benefit-cost analysis to estimate the economic value of non-market goods such as environmental quality. In CV, surveys are used to ask people about their willingness to pay for a good in a hypothetical market situation. In this application, homeowners in Baltimore County were asked about their willingness to pay (WTP) for programs to control pollutants in urban stormwater runoff designed to achieve, respectively, 4% and 1% reductions in nutrient loadings to the Chesapeake Bay. The main variation comprised alternate descriptions of the payment vehicle. Tests show that the mean WTP by means of property taxes does not differ significantly from mean WTP via user charges. This result was somewhat surprising because of other evidence that the respondents believe strongly that user charges are fairer than property taxes. A best estimate of the benefits to homeowners in Baltimore County of controlling nutrient loads for urban stormwater is from $1.2 to $4.2 million annually, depending on the reduction objective.

    The Baltimore Applications Project (BAP), an experiment jointly conducted by the City of Baltimore and the National Aeronautics and Space Administration (NASA), was begun in May 1974 in response to a request by the City. The main purpose of the BAP is the identification of technology for beneficial application to the City operations. An independent evaluation, performed after three years of operation, indicates very good project results and confirms the choices of the experiment's basic features. The BAP demonstrates one way to achieve successful intergovernmental transfer of Federal technology.

    2015-04-01

    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 were

    This report presents an illustrative case study using the EPRI technology choice model (TCM). This model is designed to help individual utilities choose technologies and explain their choices. It allows utilities to compare the economic and environmental effects of different technologies using management's judgment about those effects. The study examines technology choice complexities, including multiple objectives, uncertainties, and the significance of timing. The Baltimore Gas and Electric Company (BGE) anticipates increased electricity demand and is considering several new coal-fired technologies for generating 600 MWe at its Perryman site in the 1990s. This case study examines the questions of which coal technology BGE should use and in which year the new facility should be scheduled for service. The technologies considered are a conventional coal-fired facility, an atmospheric fluidized-bed facility, a KILnGAS integrated coal gasification - combined-cycle (IGCC) facility, and a Texaco IGCC facility.

    The NASA/Baltimore Applications Project operating at the Goddard Space Flight Center was called upon by the Housing Authority of Baltimore City to consider the problems of providing low cost public housing because of increased energy costs and suggest methods for correction and alleviation. The first step chosen was to elicit as many different options for solution as possible through means of a Public Housing Energy Workshop held in Easton, Md. in September 1980. A final role for the Workshop was a listing and qualifying of each alternative as to its suitability and cost. Specific areas were examined by three panels: (1) Systems, (2) Conservation and Motivation, and (3) Fuels. Each panel was made up of persons from differing but appropriate backgrounds; membership was not restricted to housing people alone. A summary of their deliberations is given - it will be used as a stepping stone to further selection and implementation of alternatives.

    Studies show that policing, when violent, and community fragmentation have a negative impact on health outcomes. This current study investigates the connection of policing and community fragmentation and public health. Using an embedded case study analysis, semi-structured interviews were conducted with 21 African-American female and male residents, ages 21-64 years of various neighborhoods of high arrest rates and health and socioeconomic depravation in Baltimore City, MD. Baltimore residents' perceptions of policing, stress, community fragmentation, and solutions are presented. Analysis of the perceptions of these factors suggests that violent policing increases community fragmentation and is a public health threat. Approaches to address this public health threat are discussed.

    1993-05-01

    327 school-based and school-linked health clinics in 33 US states and Puerto Rico provide comprehensive adolescent health care and social services to underserved populations. In January 1993, the Laurence Paquin School (grades 7-12) for pregnant students and teenage mothers in Baltimore, Maryland, began a private-funded pilot programs offering students subdermal contraceptive implants as an option. The Baltimore City Health Department wants to offer the implants to students at 5 other high school-based clinics beginning in the autumn of 1993. Teenagers at schools other than Paquin School already receive information about the implants and can be referred to a Baltimore City family planning clinic, a Planned Parenthood clinic, or other health provider. Before the pilot program, the Health Department identified a group of providers who could provide accurate information about implants and dispel misconceptions about insertion and possible side effects in order to guarantee adolescents access to implants. Even though Maryland law does not require parental consent, all Baltimore school-based clinic staff try to involve parents during counseling and treatment. In fact, as of May 1993, all Paquin students accepting Norplant had present at the two mandatory counseling sessions and actual insertion procedure. During the counseling sessions, they heard repeated recommendations to also use condoms to protect against AIDS and sexually transmitted diseases. Students at Paquin received information again prior to insertion, thereby granting them the opportunity to ask more questions or to decide against the implants. The pilot program received negative media, but the students and the principal agreed that the media disregarded the reality of the students' lives. Further, the parents and students asked that the implants be made available and the health department did not impose them on the students as many groups and the media implied. PMID:12286472

    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.

    Reduced access to affordable healthy foods is linked to higher rates of chronic diseases in low-income urban settings. The authors conduct a feasibility study of an environmental intervention (Baltimore Healthy Stores) in seven corner stores owned by Korean Americans and two supermarkets in low-income East Baltimore. The goal is to increase the availability of healthy food options and to promote them at the point of purchase. The process evaluation is conducted largely by external evaluators. Participating stores stock promoted foods, and print materials are displayed with moderate to high fidelity. Interactive consumer taste tests are implemented with high reach and dose. Materials developed specifically for Korean American corner store owners are implemented with moderate to high fidelity and dose. Results indicate that small food store-based intervention programs are feasible to implement and are a viable means of increasing healthy food availability and a good location for point-of-purchase promotions in low-income urban settings.

    Reduced access to affordable healthy foods is linked to higher rates of chronic diseases in low-income urban settings. The authors conduct a feasibility study of an environmental intervention (Baltimore Healthy Stores) in seven corner stores owned by Korean Americans and two supermarkets in low-income East Baltimore. The goal is to increase the availability of healthy food options and to promote them at the point of purchase. The process evaluation is conducted largely by external evaluators. Participating stores stock promoted foods, and print materials are displayed with moderate to high fidelity. Interactive consumer taste tests are implemented with high reach and dose. Materials developed specifically for Korean American corner store owners are implemented with moderate to high fidelity and dose. Results indicate that small food store-based intervention programs are feasible to implement and are a viable means of increasing healthy food availability and a good location for point-of-purchase promotions in low-income urban settings.

    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 North-East Corridor project aims to use a top-down inversion method to quantify sources of Greenhouse Gas (GHG) emissions in the urban areas of Washington DC and Baltimore at approximately 1km2 resolutions. The aim of this project is to help establish reliable measurement methods for quantifying and validating GHG emissions independently of the inventory methods typically used to guide mitigation efforts. Since inversion methods depend on atmospheric observations of GHG, deploying a suitable network of ground-based measurement stations is a fundamental step in estimating emissions from the perspective of the atmosphere with reasonable levels of uncertainty. The purpose of this work is to design a tower based network of measurement stations that can reduce the uncertainty in emissions by 50% in the central areas of DC and Baltimore. To this end, the Weather Research and Forecasting Model (WRF-ARW) was used along with the Stochastic Time-Inverted Lagrangian Transport model (STILT) to derive the sensitivity of hypothetical observations to surface emissions (footprints) for the months of February and July 2013. An iterative selection algorithm, based on k-means clustering method, was applied in order to minimize the similarities between the temporal response of each site and maximize the urban contribution. Afterwards, a synthetic inversion Kalman Filter was used to evaluate the performances of the observing system based on the merit of the retrieval over time and the amount of a priori uncertainty reduced by the network. We present the performances of various measurement networks that consist of different number of towers and where the location of these towers vary. Results show that too compact networks lose spatial coverage whilst too spread networks lose capabilities of constraining uncertainties in the fluxes. In addition, we explore the possibility of using a very high density network of low-cost, low-accuracy sensors characterized by larger uncertainties and

    OBJECTIVE: Our first objective was to develop an index of satellite exchange and then determine whether satellite exchangers (SEs) differed demographically or behaviorally from other injecting drug users (IDUs). Our second objective was to determine the degree that SEs contributed to needle exchange program (NEP) effectiveness. METHODS: We collected data from approximately 5000 Baltimore Needle Exchange Program (BNEP) participants on the number of syringes acquired and returned over the two-year period February 1995 to February 1997. We then conducted one-way ANOVAs and logistic regressions to determine if SEs were different from other IDUs. RESULTS: We classified 9.35% of the IDUs and SEs and showed that SEs reported levels of drug use and risk behavior similar to other BNEP participants. Although SEs represented less than 10% of all BNEP clients, they accounted for more than 64% of all needles distributed by the BNEP. We showed that SEs accessed more wide-ranging drug use networks than non-SE IDUs and thus can act as potential bridges for human immunodeficiency virus (HIV) prevention materials and messages to larger numbers of drug injectors. CONCLUSIONS: SEs can be expressly targeted with specific prevention messages and encouraged to be "ambassadors" for HIV prevention messages. Efforts to curtail the activities of SEs may detract from the effectiveness of NEPs. PMID:9722814

  4. Modeling ozone episodes in the Baltimore-Washington region

    1994-01-01

    Surface ozone (O3) concentrations in excess of the National Ambient Air Quality Standard (NAAQS) continue to occur in metropolitan areas in the United States despite efforts to control emissions of O3 precursors. Future O3 control strategies will be based on results from modeling efforts that have just begun in many areas. Two initial questions that arise are model sensitivity to domain-specific conditions and the selection of episodes for model evaluation and control strategy development. For the Baltimore-Washington region (B-W), the presence of the Chesapeake Bay introduces a number of issues relevant to model sensitivity. In this paper, the specific questions of the determination of model volume (mixing height) for the Urban Airshed Model (UAM) is discussed and various alternative methods compared. For the latter question, several analytic approaches, Cluster Analysis and classification and Regression Tree (CART) analysis are undertaken to determine meteorological conditions associated with severe O3 events in the B-W domain.

    Hydrocoelom and lymphedema are common in amphibians. In the family Dendrobatidae at the National Aquarium, Baltimore, prevalence was 3.19% from 2005 to 2011. Complete review of all cases in dendrobatids from 01 January 2003 to 01 June 2011 at the National Aquarium identified annual incidence rate, associated signs, diagnostic findings, therapeutics, and outcomes using medical record review. Associated etiologies were assessed via available necropsy and histopathology reports. Hydrocoelom was defined as coelomic distention with fluid; lymphedema was defined as fluid accumulation in the lymph spaces. These two syndromes could occur concurrently, and no association between case success (36.5% overall) or etiology was found to contrast hydrocoelom and lymphedema. Species susceptibility varied, with increased prevalence and incidence rate in Adelphobates castaneoticus, Dendrobates auratus, and Phyllobates spp. D. auratus also had reduced case success overall (26.0%). Females experienced hydrocoelom and/or lymphedema at an attack rate more than three times that of males. Fluid aspiration for culture was the most predictive antemortem diagnostic to find infectious etiologies, but antemortem diagnostics were largely noncontributory in identifying other causes of fluid accumulation. Enrofloxacin treatment increased case success more than fivefold when compared to those not treated and was the only treatment positively associated with case success. Infectious etiology, renal disease, and gastrointestinal disease, including parasitism, were seen commonly on postmortem evaluation of cases. These findings underscore the importance of the ability to individually track and treat cases, with fluid culture and initiation of enrofloxacin therapy (10 mg/kg p.o.q. 24 hr) seen as the best first steps after presentation with hydrocoelom or lymphedema.

    This study is one of the first to explore the relevance of trust to the health of adolescents living in a disadvantaged urban setting. The primary objectives were to determine the differences in the sociodemographic characteristics between adolescents who do and do not trust and to examine the associations between trust and health. Data were drawn from the Well-Being of Adolescents in Vulnerable Environments (WAVE) study, which is a cross-sectional global study of adolescents in very low-income urban settings conducted in 2011-2013. This paper focused on 446 adolescents in Baltimore as it was the primary site where trust was explicitly measured. For the main analyses, six health outcomes were examined: (1) self-rated health; (2) violence victimization; (3) binge drinking; (4) marijuana use; (5) post-traumatic stress disorder (PTSD); and (6) condom use at last sex. Independent variables included sociodemographic variables (age, gender, current school enrolment, perceived relative wealth, and family structure) and two dimensions of trust: community trust (trust in individuals/groups within neighborhood) and institutional trust (trust in authorities). The results show that more than half the sample had no trust in police, and a high proportion had no trust in other types of authority. Among girls, those with higher levels of community trust were less likely to be victimized and involved in binge drinking. Meanwhile, girls with higher levels of institutional trust were more likely to use a condom and less likely to have used marijuana. Among boys, those with higher levels of community trust were more likely to use a condom, while those with higher levels of institutional trust were less likely to use marijuana, but more likely binge drink. Overall, this study highlights the importance of trust for adolescent health. Most surprising were the differences in the associations between boys and girls with regard to the type of trust and specific health outcome that was

  8. Receptor modeling for multiple time resolved species: The Baltimore supersite

    A number of advances have been made toward solving receptor modeling problems using advanced factor analysis methods. Most recently, a factor analysis method has been developed for source apportionment utilizing aerosol compositional data with varying temporal resolution. The data used in that study had time resolutions ranged from 10 min to 1 h. In this work, this expanded model is tested using a data set from the Ponca Street site of the Baltimore supersite with time resolutions ranging from 30 min to 24 h. The nature of this data set implies that traditional eigenvalue-based methods cannot adequately resolve source factors for the atmospheric situation under consideration. Also, valuable temporal information is lost if one averaged or interpolated data in an attempt to produce a data set of the identical time resolution. Each data point has been used in its original time schedule and the source contributions were averaged to correspond to the specific sampling time interval. A weighting coefficient, w24, was incorporated in the modeling equations in order to improve data fitting for the 24-h data in the model. A total of nine sources were resolved: oil-fired power plant (2%), diesel emissions (1%), secondary sulfate (23%), coal-fired power plant (3%), incinerator (9%), steel plant (12%), aged sea salt (1%), secondary nitrate (23%), and spark-ignition emissions (26%). The results showed the very strong influence of the adjacent interstate highways I-95 and I-895 as well as the tunnel toll booths located to the south of the sampling site. Most of the sulfate observed was found to be associated with distant coal-fired power plants situated in the heavily industrialized midwestern parts of the United States. The contribution of the steel plant (<10 miles, 141°SE) to the observed PM concentrations (12%) was also significant.

    Background Chlamydia trachomatis (Ct) is the most frequently reported infectious disease in the U.S. This article reports population and subpopulation prevalence estimates of Ct and correlates of infection among 15-35 year-olds in Baltimore, MD, USA. Methods The Monitoring STIs Survey Program (MSSP) monitored STI prevalence among probability samples of residents of Baltimore, a city with high STI rates. MSSP respondents completed telephone audio computer-assisted self-interviews and provided biospecimens for STI testing. Results Among 2120 Baltimore residents aged 15 to 35 years, the estimated prevalence of chlamydia was 3.9% (95% Cl: 2.8, 5.0). Prevalence was 5.8% (95% Cl: 4.1, 7.6) among black MSSP respondents versus 0.7% (95% Cl: 0.0, 1.4) among nonblack respondents; all but four infections detected were among black respondents. Sexual behaviors and other factors associated with infection were far more prevalent among black than nonblack Baltimore residents. Racial disparities persisted after adjustment for sociodemographic, behavioral and health factors. Conclusion The MSSP highlights a higher Ct prevalence among young people in Baltimore than in the U.S. overall, with notable racial disparities in infection and associated risk behaviors. Public health efforts are needed to improve the diagnosis and treatment of asymptomatic infections in this population. PMID:21844726

  11. Sediment accumulation and water volume in Loch Raven Reservoir, Baltimore County, Maryland

    Banks, William S.L.; LaMotte, Andrew E.

    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.

  12. Trends in emissions and concentrations of air pollutants in the lower troposphere in the Baltimore/Washington airshed from 1997 to 2011

    2013-08-01

    Trends in the composition of the lower atmosphere (0-1500 m altitude) and surface air quality over the Baltimore/Washington area and surrounding states were investigated for the period from 1997 to 2011. We examined emissions of ozone precursors from monitors and inventories as well as ambient ground-level and aircraft measurements to characterize trends in air pollution. The US EPA Continuous Emissions Monitoring System (CEMS) program reported substantial decreases in emission of summertime nitrogen oxides (NOx) from power plants, up to ∼80% in the mid-Atlantic States. These large reductions in emission of NOx are reflected in a sharp decrease of ground-level concentrations of NOx starting around 2003. The decreasing trend of tropospheric column CO observed by aircraft is ∼0.8 Dobson unit (DU) per year, corresponding to ∼35 ppbv yr-1 in the lower troposphere (the surface to 1500 m above ground level). Satellite observations of long-term, near-surface CO show a ∼40% decrease over western Maryland between 2000 and 2011; the same magnitude is indicated by aircraft measurements above these regions upwind of the Baltimore/Washington airshed. With decreasing emissions of ozone precursors, the ground-level ozone in the Baltimore/Washington area shows a 0.6 ppbv yr-1 decrease in the past 15 yr. Since photochemical production of ozone is substantially influenced by ambient temperature, we introduce the climate penalty factor (CPF) into the trend analysis of long-term aircraft measurements. After compensating for inter-annual variations in temperature, historical aircraft measurements indicate that the daily net production of tropospheric ozone over the Baltimore/Washington area decreased from ∼20 ppbv day-1 in the late 1990s to ∼7 ppbv day-1 in the early 2010s during ozone season. A decrease in the long-term column ozone is observed as ∼0.2 DU yr-1 in the lowest 1500 m, corresponding to an improvement of ∼1.3 ppbv yr-1. Our aircraft

    2007-12-01

    The purpose of this project is to quantify the urban water cycle, with an emphasis on urban groundwater, using investigations at multiple spatial scales. The overall study focuses on the 171 sq km Gwynns Falls watershed, which spans an urban to rural gradient of land cover and is part of the Baltimore Ecosystem Study LTER. Within the Gwynns Falls, finer-scale studies focus on the 14.3 sq km Dead Run and its subwatersheds. A coarse-grid MODFLOW model has been set up to quantify groundwater flow magnitude and direction at the larger watershed scale. Existing wells in this urban area are sparse, but are being located through mining of USGS NWIS and local well data bases. Wet and dry season water level synoptics, stream seepage transects, and existing permeability data are being used in model calibration. In collaboration with CUAHSI HMF Geophysics, a regional-scale microgravity survey was conducted over the watershed in July 2007 and will be repeated in spring 2008. This will enable calculation of the change in groundwater levels for use in model calibration. At the smaller spatial scale (Dead Run catchment), three types of data have been collected to refine our understanding of the groundwater system. (1) Multiple bromide tracer tests were conducted along a 4 km reach of Dead Run under low-flow conditions to examine groundwater- surface water exchange as a function of land cover type and stream position in the watershed. The tests will be repeated under higher base flow conditions in early spring 2008. Tracer test data will be interpreted using the USGS OTIS model and results will be incorporated into the MODFLOW model. (2) Riparian zone geophysical surveys were carried out with support from CUAHSI HMF Geophysics to delineate depth to bedrock and the water table topography as a function of distance from the stream channel. Resistivity, ground penetrating radar, and seismic refraction surveys were run in ten transects across and around the stream channels. (3) A finer

    Cardiovascular disease (CVD) disparities continue to have a negative impact on African Americans in the United States, largely because of uncontrolled hypertension. Despite the availability of evidence-based interventions, their use has not been translated into clinical and public health practice. The Johns Hopkins Center to Eliminate Cardiovascular Health Disparities is a new transdisciplinary research program with a stated goal to lower the impact of CVD disparities on vulnerable populations in Baltimore, Maryland. By targeting multiple levels of influence on the core problem of disparities in Baltimore, the center leverages academic, community, and national partnerships and a novel structure to support 3 research studies and to train the next generation of CVD researchers.

    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.

    This study assessed the impact of a youth-targeted multilevel nutrition intervention in Baltimore City. The study used a clustered randomized design in which 7 recreation centers and 21 corner stores received interventions and 7 additional recreation centers served as comparison. The 8-month intervention aimed to increase availability and selection of healthful foods through nutrition promotion and education using point-of purchase materials such as posters and flyers in stores and interactive sessions such as taste test and cooking demonstrations. Two hundred forty-two youth-caregiver dyads residing in low-income areas of Baltimore City recruited from recreation centers were surveyed at baseline using detailed instruments that contained questions about food-related psychosocial indicators (behavioral intentions, self-efficacy, outcome expectancies, and knowledge), healthful food purchasing and preparation methods, and anthropometric measures (height and weight). The Baltimore Healthy Eating Zones intervention was associated with reductions in youth body mass index percentile (p = .04). In subgroup analyses among overweight and obese girls, body mass index for age percentile decreased significantly in girls assigned to the intervention group (p = .03) and in girls with high exposure to the intervention (p = .013), as opposed to those in comparison or lower exposure groups. Intervention youth significantly improved food-related outcome expectancies (p = .02) and knowledge (p < .001). The study results suggest that the Baltimore Healthy Eating Zones multilevel intervention had a modest impact in reducing overweight or obesity among already overweight low-income African American youth living in an environment where healthful foods are less available. Additional studies are needed to determine the relative impact of health communications and environmental interventions in this population, both alone and in combination.

  16. Modeling and imaging land-cover influences on air temperature in and near Baltimore, MD

    NASA Astrophysics Data System (ADS)

    Heisler, Gordon M.; Ellis, Alexis; Nowak, David J.; Yesilonis, Ian

    2016-04-01

    Over the course of 1681 hours between May 5 and September 30, 2006, air temperatures measured at the 1.5-m height at seven sites in and near the city of Baltimore, MD were used to empirically model Δ widehat{T} R-p , the difference in air temperature between a site in downtown Baltimore and the six other sites. Variables in the prediction equation included difference between the downtown reference and each of the other sites in upwind tree cover and impervious cover as obtained from 10-m resolution geographic information system (GIS) data. Other predictor variables included an index of atmospheric stability, topographic indices, wind speed, vapor pressure deficit, and antecedent precipitation. The model was used to map predicted hourly Δ widehat{T} R-p across the Baltimore region based on hourly weather data from the airport. Despite the numerous sources of variability in the regression modeling, the method produced reasonable map patterns of Δ widehat{T} R-p that, except for some areas evidently affected by sea breeze from the Chesapeake, closely matched results of mesoscale modeling. Potential applications include predictions of the effect of changing tree cover on air temperature in the area.

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

    SciTech Connect

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

    1995-12-31

    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.

  18. Hot in Baltimore: linking urban form to fine-scale temperature differences

    NASA Astrophysics Data System (ADS)

    Scott, A.; Waugh, D.; Zaitchik, B. F.; Guikema, S.

    2015-12-01

    Better understanding how urban morphology creates microclimates can help policymakers and planners mitigate the effects of heatwaves and other negative urban heat island effects. In Baltimore, where the observed downtown-rural temperature difference (as measured by NOAA stations) can reach 5°C, low-income neighborhoods are almost entirely covered by impervious surfaces like concrete but lack trees and parks. Their urban-rural temperature difference is then expected to exceed the reported one. However, that difference is not well quantified because these areas lack weather station coverage. Additionally, high resolution satellite imagery shows only land surface temperatures (inadequate for policy and health interventions) and may miss severe heat events. To remedy this, a low-cost monitoring network was installed in East Baltimore over summer 2015 aiming to characterize spatial and temporal variability and examine how heat excess varies during heat events. Results confirm that E. Baltimore exceeds downtown temperatures and show that a dense network of low cost sensors can help attribute temperature anomalies to local features such as land cover, building density and tree canopy.

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

    PubMed

    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.

  20. Biological aging and social characteristics: gerontology, the Baltimore city hospitals, and the National Institutes of Health.

    PubMed

    Park, Hyung Wook

    2013-01-01

    The intramural gerontological research program in the National Institutes of Health underwent a substantial growth after its creation within the precincts of the Baltimore City Hospitals in 1940. This paper analyzes its development and the associated problems of its early years. Gerontologists aimed at improving the social and economic life of the elderly through scientific research. With this aim in mind, they conducted various investigations using the indigent aged patients of the Baltimore City Hospitals. Yet the scientists of aging, who hoped to eliminate negative social factors that might bias their research and heighten the confusion between pathology and aging per se, eventually stopped using these patients in the hospital as human subjects. Instead they sought educated affluent subjects in order to eliminate the impact of poverty. By doing so, however, they introduced a new source of social bias to their work, especially within the novel project begun in 1958, the Baltimore Longitudinal Study of Aging. This article thus examines the context of the development of gerontologists' research by analyzing their agenda, institutional environment, and research subjects in the 1940s and the 1950s.

    2014-10-01

    This research project compares laboratory-measured fuel economy of a medium-duty diesel powered hydraulic hybrid vehicle drivetrain to both a conventional diesel drivetrain and a conventional gasoline drivetrain in a typical commercial parcel delivery application. Vehicles in this study included a model year 2012 Freightliner P100H hybrid compared to a 2012 conventional gasoline P100 and a 2012 conventional diesel parcel delivery van of similar specifications. Drive cycle analysis of 484 days of hybrid parcel delivery van commercial operation from multiple vehicles was used to select three standard laboratory drive cycles as well as to create a custom representative cycle. These four cycles encompass and bracket the range of real world in-use data observed in Baltimore United Parcel Service operations. The NY Composite cycle, the City Suburban Heavy Vehicle Cycle cycle, and the California Air Resources Board Heavy Heavy-Duty Diesel Truck (HHDDT) cycle as well as a custom Baltimore parcel delivery cycle were tested at the National Renewable Energy Laboratory's Renewable Fuels and Lubricants Laboratory. Fuel consumption was measured and analyzed for all three vehicles. Vehicle laboratory results are compared on the basis of fuel economy. The hydraulic hybrid parcel delivery van demonstrated 19%-52% better fuel economy than the conventional diesel parcel delivery van and 30%-56% better fuel economy than the conventional gasoline parcel delivery van on cycles other than the highway-oriented HHDDT cycle.

    In 1992, The Baltimore City Department of Public Works initiated aggressive, proactive measures to guard against the infiltration of zebra mussels into local reservoirs and river supplies, which provide raw and finished water to more than 1.6 million people in the City and five neighboring counties. After months of detailed study and planning, Baltimore City appropriated $3.66 million in July 1994 to construct zebra mussel control facilities. Three of the structures will house units that inject controlled doses of potassium permanganate into water intake pipes located in the Liberty and Loch Raven reservoirs and the Susquehanna River. In the event the zebra mussel makes its way into Maryland waters, the chemical would create a hostile environment for the mollusk preventing the mussels` colonization in the more than 20 miles of water tunnels that lead to area filtration plants. Though chlorine is preferred chemical for control in other municipalities, studies indicate that chlorine by-products, known as trihalomethanes, would near or exceed future Environmental Protection Agency standards (a maximum of 80 parts per billion) for drinking water. Consequently, it was decided to use potassium permanganate as the primary control chemical, with chlorine as an emergency backup. In addition, the City plans to construct a thermal control system as the Prettyboy reservoir intake to control the mussel threat without harming the thriving trout population found downstream from the dam. Baltimore City officials have also spearheaded a program using innovative posters to heighten public awareness to the potential harm that can result from the careless transportation of zebra mussels from infested to uninhabited waters. The City`s actions have helped ensure protected waters for Maryland residents and reduced the need for additional public spending to defend against the stealthy intruder.

  6. Development and implementation of the Baltimore healthy carry-outs feasibility trial: process evaluation results

    PubMed Central

    2013-01-01

    Background Prepared food sources, including fast food restaurants and carry-outs, are common in low-income urban areas. These establishments provide foods high in calories, sugar, fat, and sodium. The aims of the study were to (1) describe the development and implementation of a carry-out intervention to provide and promote healthy food choices in prepared food sources, and (2) to assess its feasibility through a process evaluation. Methods To promote healthy eating in this setting, a culturally appropriate intervention was developed based on formative research from direct observation, interviews and focus groups. We implemented a 7-month feasibility trial in 8 carry-outs (4 intervention and 4 comparison) in low-income neighborhoods in Baltimore, MD. The trial included three phases: 1) Improving menu boards and labeling to promote healthier items; 2) Promoting healthy sides and beverages and introducing new items; and 3) Introducing affordable healthier combo meals and improving food preparation methods. A process evaluation was conducted to assess intervention reach, dose received, and fidelity using sales receipts, carry-out visit observations, and an intervention exposure assessment. Results On average, Baltimore Healthy Carry-outs (BHC) increased customer reach at intervention carry-outs; purchases increased by 36.8% at the end of the study compared to baseline. Additionally, menu boards and labels were seen by 100.0% and 84.2% of individuals (n = 101), respectively, at study completion compared to baseline. Customers reported purchasing specific foods due to the presence of a photo on the menu board (65.3%) or menu labeling (42.6%), suggesting moderate to high dose received. Promoted entrée availability and revised menu and poster presence all demonstrated high fidelity and feasibility. Conclusions The results suggest that BHC is a culturally acceptable intervention. The program was also immediately adopted by the Baltimore City Food Policy Initiative as

    Understanding the dynamics of water exchange between Baltimore Harbor and the Chesapeake Bay is essential when evaluating transport and fate of dissolved substances in both of these systems. Conservative artificial tracers are used in this study to investigate transport processes through a three-dimensional hydrodynamic model (CH3D). The model well reproduced the three-layered circulation pattern in Baltimore Harbor. Several numerical experiments are performed to trace the water mass coming from different sources. The results indicate that both the upper and lower layers of the Harbor are the dominant pathways of transporting dissolved substances from Susquehanna River to the Harbor. Such inward transport is intensified (suppressed) during the high-discharge (low-discharge) period. The upper layer inflow transports water mass with high concentrations of dissolved substances while the inflow from the lower layer transports water mass with low concentrations of dissolved substances. The bottom layer is the dominant pathway for transporting dissolved substances from the lower Bay to the Harbor. Lower river discharge and stronger along-Bay pressure gradient (resulting in stronger landward residual flow in the bottom layer of the Bay) facilitate the bottom intrusion of dissolved substances from lower Bay to the Harbor. Once contaminants are transported into the Harbor, they usually stay for a longer time in the mid-depth of the Harbor than those in other layers due to the three-layer circulation in the Harbor. The time needed for the contaminants being transported out of the Harbor during a typical low-discharge period is about 1 month longer than that needed during a typical high-discharge period. The results, from the environmental perspective, provide new insights for quantitative evaluation on the transport processes of the dissolved biogeochemical substances between Baltimore Harbor and Chesapeake Bay.

    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.

    The Forum on Geologic mapping applications in the Washington-Baltimore urban area was convened on April 23, 1997, at Reston, Virginia. The forum was cosponsored by the U.S. Geological Survey and the Maryland Geological Survey, with assistance from the Virginia Division of Mineral Resources. Spatial earth science information in the Washington-Baltimore area provides a scientific framework for environmental assessment, urban planning, and future resource and hazard investigations in this area of the Chesapeake Bay watershed, which has sustained three centuries of urban growth.

  16. Middle and upper jurassic depositional environments at outer shelf and slope of Baltimore Canyon Trough

    1985-04-01

    New CDP data acquired in the Baltimore Canyon Trough during project LASE made it possible to map a continuous Jurassic sedimentary sequence from the continental margin to the abyssal plain without interruption by basement structures. Intense carbonate sedimentation is inferred at the outer shelf during the Middle and Late Jurassic. Carbonate sedimentation probably started during the Middle Jurassic with a platform that prograded seaward with the development of ramps. By the Late Jurassic, a major reef complex had developed at the outer continental shelf. The onset of reef growth can be tentatively dated as 138 Ma by using the J1 reflector dated by the Deep Sea Drilling Project. A well-developed reef-talus deposit can be identified overlying the interface that generates the J1 reflector. A detailed analysis of semblancederived interval velocities in the reef-talus sequence indicates a compressional velocity of 4.3-4.5 km/sec (14,100-14,800 ft/sec) for that interval, which was part of a major barrier reef along the United States eastern margin. After the reef formed, the deep oceanic basin was mostly starved from shelf-derived sediments until the reef died and was buried by clastic sediments. By correlation of our seismic data and COST well information, that in the Baltimore Canyon Trough this reef had terminated by about the end of the Jurassic Period.

    2002-05-01

    We present the first results from the Baltimore Bomem Atmospheric Emitted Radiance Interferometer (BBAERI), a commercial prototype Fourier Transform Infrared Interferometer (FTIR) atmospheric sounding system. Developed by ABB Bomem in collaboration with the University of Wisconsin-Madison (UW), the first prototype was christened BBAERI and deployed to the University of Maryland, Baltimore County (UMBC). With similar operational specifications and capabilities to the AERI's designed and built by UW for the United States Department of Energy (DOE) Atmospheric Radiation Measurement (ARM) Program, BBAERI opens a new window on atmospheric remote sensing. Side-by-side operation of BBAERI with the portable UW AERI-00 deployed at UMBC in August 2001 yielded excellent results and confirmed the radiometric calibration of BBAERI. Temperature and moisture profiles retrieved from BBAERI spectra will be presented and compared to available nearby radiosonde soundings. A basic cloud clearing algorithm which utilizes the BBAERI spectrum to distinguish between clear and cloudy scenes will also be presented. Retrievals of boundary layer and mean free tropospheric carbon monoxide abundances indicate significant local pollution sources, as expected for an urban location, as well as synoptic and seasonal variations. BBAERI started autonomous operation at UMBC on June 22, 2001, and will see field deployments from 2002-2004 to the United States Coast Guard Chesapeake Light lighthouse platform 25~km due east of Virginia Beach, VA for validation of NASA's Atmospheric InfraRed Sounder (AIRS).

    Objectives. We assessed the prevalence of recreational activities in the waterways of Baltimore, MD, and the risk of exposure to Cryptosporidium among persons with HIV/AIDS. Methods. We studied patients at the Johns Hopkins Moore Outpatient AIDS Clinic. We conducted oral interviews with a convenience sample of 157 HIV/AIDS patients to ascertain the sites used for recreational water contact within Baltimore waters and assess risk behaviors. Results. Approximately 48% of respondents reported participating in recreational water activities (fishing, crabbing, boating, and swimming). Men and women were almost equally likely to engage in recreational water activities (53.3% versus 51.3%). Approximately 67% (105 of 157) ate their own catch or that of friends or family members, and a majority (61%, or 46 of 75) of respondents who reported recreational water contact reported consumption of their own catch. Conclusions. Baltimoreans with HIV/AIDS are engaging in recreational water activities in urban waters that may expose them to waterborne pathogens and recreational water illnesses. Susceptible persons, such as patients with HIV/AIDS, should be cautioned regarding potential microbial risks from recreational water contact with surface waters. PMID:19372505

  19. Flood-Producing Rainfall and Storm Event Hydrologic Response in Urban Watersheds near Baltimore, MD

    2012-12-01

    Previous work has shown a spectrum of storm event hydrologic response across watersheds in the Baltimore, MD metropolitan area. Differences in storm event hydrologic response between urban basins cannot be explained by impervious surface or land use alone. We further explore these differences through a closer look at flood-producing rainfall properties and through numerical experimentation using a watershed model. Rainfall analyses utilize a high resolution radar rainfall dataset (1-km and 15-min resolution, processed through Hydro-NEXRAD and bias corrected) for a ten-year period from 2000-2009. Spatial heterogeneities in flood-producing rainfall suggest that some urban basins may be more prone to flooding due to higher rainfall intensities over the basin. For example, Moores Run, the flashiest basin in the contiguous United States, is located near a rainfall maximum to the northeast of Baltimore. Spatial patterns of flood-producing rainfall vary between urban and non-urban basins. We examine contrasts in storm structure and evolution for storms producing flood in urban and non-urban watersheds. Storm event hydrologic response is examined through analyses using a watershed model of the Dead Run basin based on the Gridded Surface/ Subsurface Hydrologic Analysis (GSSHA) model. The model is used to explore the sensitivity of urban storm event hydrologic response to properties of urban soils, surface and storm drain network structure, and detention basin storage.

    The declining size of the Baltimore Harbor black-crowned night heron (Nycticorax nycticorax) colony has been hypothesized to be linked to PCB exposure. In 1998, a 'sample egg' was collected from 65 black-crowned night heron nests (each containing > three eggs) for contaminant analysis, and the remaining eggs in these 65 nests, plus four two-egg nests, were monitored for hatching and fledging success. Eggs were also collected from 12 nests at Holland Island, a reference site in southern Chesapeake Bay. Samples were analyzed for 26 organochlorine pesticides and metabolites, and 145 PCB congeners. Pesticide and metabolite concentrations, including p,p'-DDE, were well below thresholds associated with adverse reproductive effects at both sites. Average concentration of total PCBs, 12 Ah receptor-active PCB congeners, and toxic equivalents in eggs from Baltimore Harbor were greater (up to 35- fold) than that observed in Holland Island samples. Overall nest success at the Baltimore Harbor heronry was estimated by the Mayfield method to be 0.74, and the mean number of young fledged/hen was 2.05, which is within published productivity estimates for maintaining a stable black-crowned night heron population. Using logistic regression, no significant relationships were found between organochlorine contaminant concentrations in sample eggs and hatching, fledging, or overall reproductive success. Processes other than poor reproduction (e.g., low post- fledging survival, emigration, habitat degradation) may be responsible for the declining size of the Baltimore Harbor colony.

    Adkins, Harold E.; Cuta, Judith M.; Koeppel, Brian J.; Guzman, Anthony D.; Bajwa, Christopher S.

    2006-11-15

    On July 18, 2001, a freight train carrying hazardous (non-nuclear) materials derailed and caught fire while passing through the Howard Street railroad tunnel in downtown Baltimore, Maryland. The United States Nuclear Regulatory Commission (USNRC), one of the agencies responsible for ensuring the safe transportation of radioactive materials in the United States, undertook an investigation of the train derailment and fire to determine the possible regulatory implications of this particular event for the transportation of spent nuclear fuel by railroad. Shortly after the accident occurred, the USNRC met with the National Transportation Safety Board (NTSB, the U.S. agency responsible for determining the cause of transportation accidents), to discuss the details of the accident and the ensuing fire. Following these discussions, the USNRC assembled a team of experts from the National Institute of Standards and Technology (NIST), the Center for Nuclear Waste Regulatory Analyses (CNWRA), and Pacific Northwest National Laboratory (PNNL) to determine the thermal conditions that existed in the Howard Street tunnel fire and analyze the effects of this fire on various spent fuel transportation package designs. The Fire Dynamics Simulator (FDS) code, developed by NIST, was used to determine the thermal environment present in the Howard Street tunnel during the fire. The FDS results were used as boundary conditions in the COBRA-SFS and ANSYS® computer codes to evaluate the thermal performance of different package designs. The staff concluded that larger transportation packages resembling the HOLTEC Model No. HI STAR 100 and TransNuclear Model No. TN-68 would withstand a fire with thermal conditions similar to those that existed in the Baltimore tunnel fire event with only minor damage to peripheral components. This is due to their sizable thermal inertia and design specifications in compliance with currently imposed regulatory requirements. The staff also concluded that some

    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.

    2010-05-01

    The U.S. has the highest rate of incarceration in the world, releasing 12 million ex-offenders each year. These ex-offenders are disproportionately male, Black, poor, under-educated, and unhealthy, and return to our nation's poorest neighborhoods. Through a survey questionnaire and focus groups, this study examined the health status, health needs, access to and utilization of health care services among a sample of ex-offenders living in transitional housing in Baltimore City. More than half reported at least two major, chronic health problems. Only 40% had any form of health coverage; even more predictive of the ability to obtain health services was being able to name a specific provider (doctor, clinic or health organization). Recommendations for halting the downward spiral of poverty and sickness for this population and their communities include providing assistance with accessing, understanding, and navigating our complex and consumer-unfriendly health care system.

    Beyer, W.N.; Kaiser, T.E.

    1984-01-01

    Moths were collected with a light trap from 15 sites in the Baltimore, Maryland - Washington, D.C. area and analyzed for organochlorine pesticide residues. On the average, the species sampled contained 0.33 ppm heptachlor-chlordane compounds, 0.25 ppm DDE, and 0.11 ppm dieldrin. There were large differences in the concentrations detected in different species. Concentrations were especially high in moths whose larvae were cutworms, and were virtually absent from moths whose larvae fed on tree leaves. It was concluded that at least some species sampled could be an important source of insecticides to insectivorous wildlife. In some instances moths may be useful indicators of environmental contamination, especially when insectivorous wildlife species cannot be collected. However, the differences in residues observed among species means that only similar species should be compared, and this limits their potential for monitoring.

    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. PMID:27081886

    Maryland (MD) recently became one of fourteen states in the United States to enact a traffic law requiring motor vehicles to pass bicyclists at a distance of greater than three feet. To our knowledge, motorist compliance with the law has never been assessed. This study measured the distance between overtaking motor vehicles and cyclists [e.g. vehicle passing distance (VPD)], to develop baseline metrics for tracking implementation of the three-foot passing law in Baltimore, MD and to assess risk factors for dangerous passes. During September and October 2011, cyclists (n=5) measured VPD using a previously published video technique (Parkin and Meyers, 2010). Cyclists logged a total of 10.8h of video footage and 586 vehicle passes on 34 bicycle commuting trips. The average trip lasted 19.5±4.9 min and cyclists were passed on average 17.2±11.8 times per trip. VPDs of three feet or less were common when cycling in standard lanes (17%; 78 of 451 passes) and lanes with a shared lane marking (e.g. sharrows) (23%; 11 of 47 passes). No passes of three feet or less occurred in bicycle lanes (0 of 88 passes). A multiple linear regression model was created, which explained 26% of the variability in VPD. Significant model variables were lane width, bicycle infrastructure, cyclist identity, and street identity. Interventions, such as driver education, signage, enforcement, and bicycle infrastructure changes are needed to influence driving behavior in Baltimore to increase motorist compliance with the three-foot law.

    The impact of urban development on surface flow has been studied extensively over the last half century, but effects on groundwater systems are still poorly understood. Previous studies of the influence of urban development on subsurface storage have not revealed any consistent pattern, with results showing increases, decreases, and negligible change in groundwater levels. In this paper, we investigated the effects of four key features that impact subsurface storage in urban landscapes. These include reduced vegetative cover, impervious surface cover, infiltration and inflow (I&I) of groundwater and storm water into wastewater pipes, and other anthropogenic recharge and discharge fluxes including water supply pipe leakage and well and reservoir withdrawals. We applied the integrated groundwater-surface water-land surface model ParFlow.CLM to the Baltimore metropolitan area. We compared the base case (all four features) to simulations in which an individual urban feature was removed. For the Baltimore region, the effect of infiltration of groundwater into wastewater pipes had the greatest effect on subsurface storage (I&I decreased subsurface storage 11.1% relative to precipitation minus evapotranspiration after 1 year), followed by the impact of water supply pipe leakage and lawn irrigation (combined anthropogenic discharges and recharges led to a 7.4% decrease) and reduced vegetation (1.9% increase). Impervious surface cover led to a small increase in subsurface storage (0.56% increase) associated with decreased groundwater discharge as base flow. The change in subsurface storage due to infiltration of groundwater into wastewater pipes was largest despite the smaller spatial extent of surface flux modifications, compared to other features.

    Urban areas are responsible for a major component of the anthropogenic greenhouse gas (GHG) emissions. Quantification of urban GHG fluxes is important for establishing scientifically sound and cost-effective policies for mitigating GHGs. Discrepancies between observations and model simulations of GHGs suggest uncharacterized sources in urban environments. In this work, we analyze and quantify fluxes of CO2, CH4, CO (and other trace species) from the Baltimore-Washington area based on the mass balance approach using the two-aircraft observations conducted in February-March 2015. Estimated fluxes from this area were 110,000±20,000 moles s-1 for CO2, 700±330 moles s-1 for CH4, and 535±188 moles s-1 for CO. This implies that methane is responsible for ~20% of the climate forcing from these cities. Point sources of CO2 from four regional power plants and one point source of CH4 from a landfill were identified and the emissions from these point sources were quantified based on the aircraft observation and compared to the emission inventory data. Methane fluxes from the Washington area were larger than from the Baltimore area, indicating a larger leakage rate in the Washington area. The ethane-to-methane ratios, with a mean of 3.3%, in the limited canister samples collected during the flights indicate that natural gas leaks and the upwind oil and natural gas operations are responsible for a substantial fraction of the CH4 flux. These observations will be compared to models using Ensemble Kalman Filter Assimilation techniques.

    Aerosol hygroscopicity was investigated using a novel dryer-humidifier system, coupled to a TSI-3563 nephelometer, to obtain the light scattering coefficient (σscat) as a function of relative humidity (RH) in hydration and dehydration modes. The measurements were performed in Porterville, CA (10 January to 6 February 2013), Baltimore, MD (3-30 July 2013), and Golden, CO (12 July to 10 August 2014). Observations in Porterville and Golden were part of the NASA-sponsored Deriving Information on Surface Conditions from Column and Vertically Resolved Observations Relevant to Air Quality project. The measured σscat under varying RH in the three sites was combined with ground aerosol extinction, PM2.5 mass concentrations, and particle composition measurements and compared with airborne observations performed during campaigns. The enhancement factor, f(RH), defined as the ratio of σscat(RH) at a certain RH divided by σscat at a dry value, was used to evaluate the aerosol hygroscopicity. Particles in Porterville showed low average f(RH = 80%) (1.42) which was attributed to the high carbonaceous loading in the region where residential biomass burning and traffic emissions contribute heavily to air pollution. In Baltimore, the high average f(RH = 80%) (2.06) was attributed to the large contribution of SO42- in the region. The lowest water uptake was observed in Golden, with an average f(RH = 80%) = 1.24 where organic carbon dominated the particle loading. Different empirical fits were evaluated using the f(RH) data. The widely used Kasten (gamma) model was found least satisfactory, as it overestimates f(RH) for RH < 75%. A better empirical fit with two power law curve fitting parameters c and k was found to replicate f(RH) accurately from the three sites. The relationship between the organic carbon mass and the species that are affected by RH and f(RH) was also studied and categorized.

  1. Improvements to lawn and garden equipment emissions estimates for Baltimore, Maryland.

    Lawn and garden equipment are a significant source of emissions of volatile organic compounds (VOCs) and other pollutants in suburban and urban areas. Emission estimates for this source category are typically prepared using default equipment populations and activity data contained in emissions models such as the U.S. Environmental Protection Agency's (EPA) NONROAD model or the California Air Resources Board's (CARB) OFFROAD model. Although such default data may represent national or state averages, these data are unlikely to reflect regional or local differences in equipment usage patterns because of variations in climate, lot sizes, and other variables. To assess potential errors in lawn and garden equipment emission estimates produced by the NONROAD model and to demonstrate methods that can be used by local planning agencies to improve those emission estimates, this study used bottom-up data collection techniques in the Baltimore metropolitan area to develop local equipment population, activity, and temporal data for lawn and garden equipment in the area. Results of this study show that emission estimates of VOCs, particulate matter (PM), carbon monoxide (CO), carbon dioxide (CO2), and nitrogen oxides (NO(x)) for the Baltimore area that are based on local data collected through surveys of residential and commercial lawn and garden equipment users are 24-56% lower than estimates produced using NONROAD default data, largely because of a difference in equipment populations for high-usage commercial applications. Survey-derived emission estimates of PM and VOCs are 24 and 26% lower than NONROAD default estimates, respectively, whereas survey-derived emission estimates for CO, CO2, and NO(x) are more than 40% lower than NONROAD default estimates. In addition, study results show that the temporal allocation factors applied to residential lawn and garden equipment in the NONROAD model underestimated weekend activity levels by 30% compared with survey-derived temporal

  4. Tokamak coordinate conventions: COCOS

    2013-02-01

    Dealing with electromagnetic fields, in particular current and related magnetic fields, yields "natural" physical vector relations in 3-D. However, when it comes to choosing local coordinate systems, the "usual" right-handed systems are not necessarily the best choices, which means that there are several options being chosen. In the magnetic fusion community such a difficulty exists for the choices of the cylindrical and of the toroidal coordinate systems. In addition many codes depend on knowledge of an equilibrium. In particular, the Grad-Shafranov axisymmetric equilibrium solution for tokamak plasmas, ψ, does not depend on the sign of the plasma current Ip nor that of the magnetic field B0. This often results in ill-defined conventions. Moreover the sign, amplitude and offset of ψ are of less importance, since the free sources in the equation depend on the normalized radial coordinate. The signs of the free sources, dp/dψ and dF2/dψ (p being the pressure, ψ the poloidal magnetic flux and F=RBφ), must be consistent to generate the current density profile. For example, RF and CD calculations (Radio Frequency heating and Current Drive) require an exact sign convention in order to calculate a co- or counter-CD component. It is shown that there are over 16 different coordinate conventions. This paper proposes a unique identifier, the COCOS convention, to distinguish between the 16 most-commonly used options. Given the present worldwide efforts towards code integration, the proposed new index COCOS defining uniquely the COordinate COnventionS required as input by a given code or module is particularly useful. As codes use different conventions, it is useful to allow different sign conventions for equilibrium code input and output, equilibrium being at the core of any calculations in magnetic fusion. Additionally, given two different COCOS conventions, it becomes simple to transform between them. The relevant transformations are described in detail.

  5. Interpretation of Conventional Mass

    Lee, Sungjun; Kim, Kwang Pyo

    The conventional mass is not a precise physical quantity but useful virtual one in mass metrology. Because the precise level of conventional mass is related to the OIML class, it is necessary to check if the assignment of weight class is under control. The documents of OIML (International Organization of Legal Metrology) D 28 and R 111 describe the limitation of the quantity in real application. In this presentation, we are trying to interpret and review the concept of conventional mass, for example, by estimating buoyancy deviation and maximum permissible error, in weight calibrations in Korea.

    1980-12-01

    With the recent price increases in imported oil and natural gas and the planned decontrol of domestic prices, geothermal and solar energy becomes competitive for residential space heating throughout most of the country. Geothermal energy could competitively provide about 40% of the national demand for space heat and domestic hot water (about 7 quads based on 1980 demands). Nearly all of the geothermal energy demand would be in high population density areas. Solar energy could competitively provide about 50% (about 9 quads) of the annual demand. Most of the solar energy demand would be concentrated in suburban and rural areas. Conventional energy should remain competitive for about 30% (about 5 quads) of the annual demand. Conventional energy demand would be concentrated in the South and as supplemental energy for solar/conventional systems. Geothermal solar, and conventional energy would be equally competitive for about 20% of the annual demand, which is why the individual market shares add to 120%.

    Sandia National Laboratories has been involved in designing, installing and evaluating security systems for various applications during the past 15 years. A systems approach to security that evolved from this experience was applied to aviation security for the Federal Aviation Administration. A general systems study of aviation security in the United States was concluded in 1987. One result of the study was a recommendation that an enhanced security system concept designed to meet specified objectives be demonstrated at an operational airport. Baltimore-Washington International Airport was selected as the site for the demonstration project which began in 1988 and will be completed in 1992. This article introduced the systems approach to airport security and discussed its application at Baltimore-Washington International Airport. Examples of design features that could be included in an enhanced security concept also were presented, including details of the proposed Ramps Area Intrusion Detection System (RAIDS).

    Poor accessibility to affordable healthy foods is associated with higher rates of obesity and diet-related chronic diseases. We present our process evaluation of a youth-targeted environmental intervention (Baltimore Healthy Eating Zones) that aimed to increase the availability of healthy foods and promote these foods through signage, taste tests and other interactive activities in low-income Baltimore City. Trained peer educators reinforced program messages. Dose, fidelity and reach-as measured by food stocking, posting of print materials, distribution of giveaways and number of interactions with community members-were collected in six recreation centers and 21 nearby corner stores and carryouts. Participating stores stocked promoted foods and promotional print materials with moderate fidelity. Interactive sessions were implemented with high reach and dose among both adults and youth aged 10-14 years, with more than 4000 interactions. Recreation centers appear to be a promising location to interact with low-income youth and reinforce exposure to messages.

    Places where we buy food influence dietary patterns, making local food environments a good example of a mass influence on population diets. Cross-cultural studies, using reliable methods, may help understanding the relationship between food environments and diet-related health outcomes. We aimed to understand cross-national differences in the local food environment between Madrid and Baltimore by comparing an average neighborhood in each city in terms of food store types, healthy food availability, and residents' pedestrian access. During 2012-2013, we assessed one neighborhood (~15,000 residents) in each city selecting median areas in terms of socio-demographic characteristics (segregation, education, aging, and population density). We collected on-field data on (a) number and types of all food stores, (b) overall healthy food availability and (c) specific availability of fruits & vegetables. Throughout a street network analysis (200m, 400m and 800m) of food stores with high healthy food availability, we estimated residents' pedestrian accessibility. We found 40 stores in Madrid and 14 in Baltimore. Small food stores carrying fresh foods in Madrid contrasted with the high presence of corner and chain convenience stores in Baltimore. In Madrid, 77% of the residents lived within less than 200m from a food store with high healthy food availability. In contrast, 95% of Baltimore's residents lived further than 400m from these stores. Our results may help promoting interventions from local city agencies to allocate resources to existing small-sized food stores, and to improve walkable urban environments. These actions may influence food choices, especially for those residents lacking access to private vehicles. PMID:27311334

    2015-04-01

    We perform numerical experiments using the Weather Research and Forecasting model to examine the influence of land surface heterogeneities on heavy convective rainfall in the Baltimore-Washington Metropolitan Area. Numerical experiments are carried out for a storm system (1-2 June 2012) in which heavy rainfall and severe weather were organized in the warm sector ahead of a rapidly moving cold front. As shown in previous studies, the environment is typical of flash flood producing storm systems for urban areas of the eastern US. The storm system produced rainfall accumulations exceeding 80 mm and major flash flooding in Baltimore watersheds. The study region is adjacent to the Chesapeake Bay and includes the second largest urban agglomeration in the eastern US. Numerical experiments examine urban impacts on rainfall using the Princeton Urban Canopy Model and the Noah Land Surface Model. We also examine the role of "Bay Breeze" circulations from the Chesapeake Bay for convective evolution. Rainfall distribution and amount are better represented for experiments using the more realistic urban canopy model. The Bay Breeze plays a central role in formation of convergence lines that are major determinants of convective evolution with the approaching line of convection. The Bay Breeze also interacts with heterogeneous surface fluxes from urban landscapes to determine moisture transport to evolving storm systems. The low-level convergence lines and water vapor transport that are induced and modified by land surface heterogeneities are crucial for the preferred locations of strong convective storms and heavy rainfall over the Baltimore Washington metropolitan area.

    2016-01-01

    Understanding the spatial distribution of soil lead has been a focus of the Baltimore Ecosystem Study since its inception in 1997. Through multiple research projects that span spatial scales and use different methodologies, three overarching patterns have been identified: (1) soil lead concentrations often exceed state and federal regulatory limits; (2) the variability of soil lead concentrations is high; and (3) despite multiple sources and the highly heterogeneous and patchy nature of soil lead, discernable patterns do exist. Specifically, housing age, the distance to built structures, and the distance to a major roadway are strong predictors of soil lead concentrations. Understanding what drives the spatial distribution of soil lead can inform the transition of underutilized urban space into gardens and other desirable land uses while protecting human health. A framework for management is proposed that considers three factors: (1) the level of contamination; (2) the desired land use; and (3) the community’s preference in implementing the desired land use. The goal of the framework is to promote dialogue and resultant policy changes that support consistent and clear regulatory guidelines for soil lead, without which urban communities will continue to be subject to the potential for lead exposure.

  19. Facies specificity of megaporosity in Mesozoic shelf-edge carbonates, Baltimore Canyon basin

    Meyer, F.O.

    1986-05-01

    Cores from three wells drilled by Shell Offshore Inc. provide insight into the evolution and distribution of porosity within the Mesozoic shelf-edge carbonates of the Baltimore Canyon basin. Significant primary and secondary megaporosity was found only in the late Kimmeridgian-Berriasian aggradational part of the paleoshelf-edge deposits. Megaporosity is patchy but shows an overall seaward decrease in abundance, averaging from about 13% in back-reed rocks to about 4% in reef-front deposits. This porosity trend parallels a basinward change from mainly freshwater to predominantly submarine diagenesis. In grain-supported reef-flat rocks, the porosity consists of some primary pores but dominantly is of secondary moldic pores. The secondary pores are fabric selective after former aragonitic fossils. Both primary and secondary pores are partly or completely filled with freshwater cements. These consist of clear, equant calcite crystals distributed as discontinuous or continuous circumgranular crusts and epitaxial rims typical of stabilized grainstones. Cementation was contemporaneous with or postdated leaching, but predated breakage of empty micritic envelopes. In reef-front deposits, megaporosity occurs as delicately dissolved fossils and porosity haloes in cemented packstones and grainstones within constructional reef cavities. These secondary pores are surrounded by at least two generations of cement. The first generation is a synsedimentary marine phase. It consists of both clear-bladed and inclusion-rich radiaxial crystals distributed chiefly as pore-lining crusts. The second generation is nonmarine, similar to the freshwater cements found in the reef-flat facies.

    Waterpipe smoking has been growing in popularity in the United States and worldwide. Most tobacco control regulations remain limited to cigarettes. Few studies have investigated waterpipe tobacco smoke exposures in a real world setting. We measured carbon monoxide (CO), particulate matter (PM)2.5, and airborne nicotine concentrations in seven waterpipe cafes in the greater Baltimore area. Area air samples were collected between two and five hours, with an average sampling duration of three hours. Waterpipe smoking behaviors were observed at each venue. Indoor air samplers for CO, PM2.5, and airborne nicotine were placed in the main seating area 1-2 m above the floor. Indoor airborne concentrations of PM2.5 and CO were markedly elevated in waterpipe cafes and exceeded concentrations that were observed in cigarette smoking bars. Air nicotine concentrations, although not as high as in venues that allow cigarette smoking, were markedly higher than in smoke-free bars and restaurants. Concentrations of PM approached occupational exposure limits and CO exceeded occupational exposure guidelines suggesting that worker protection measures need to be considered. This study adds to the literature indicating that both employees and patrons of waterpipe venues are at increased risk from complex exposures to secondhand waterpipe smoke. PMID:24736103

    Results of exploratory drilling, by Shell Offshore Inc., and its partners, of the Late Jurassic-Early Cretaceous carbonate margin of the Baltimore Canyon (BC) basin can be interpreted directly from the better understood, time-equivalent Nova Scotian (NS) basin stratigraphy. The BC paleomargin was constructed in a depositional cycle of three successive stages: Oxfordian-early Kimmeridgian progradation, Kimmeridgian-Berriasian aggradation, Berriasian-Valanginian drowning. The upper two stages in NS are the Baccaro and Artimon members of the Abenaki formation. The progradation of the lower sequence in BC results from high clastic input and has a parallel (not age equivalent) in NS only in proximity to the Sable Island paleodelta. Both basins have similar, complementary, shelf-edge environments that form a single water-depth-controlled biotic zonation. This zonation is: shallow-water stromatoporoid-hexacoral biostromes and reefs; deeper water stromatactis and thrombolitic mud mounds; and deep-water lithistid sponge reefs. Associated environments are oncolitic reef flats, reef-apron skeletal sands, slope reef debris from sponge and coral reefs, and back-reef mollusk-rich skeletal and skeletal-oolitic sands. Major differences between the basins are the pinnacle reefs of BC and the contrast between the mud-rich skeletal and nonskeletal megafacies of NS versus the dominantly skeletal sand-rich BC sediments. The higher subsidence rates of BC may explain both differences.

    Homeless youth suffer from high rates of health problems, yet little is known about their perceptions of or context for their own health issues. In this study, a combination of qualitative techniques from participatory rural appraisal and rapid assessment procedures was used to investigate the perceptions of health needs of shelter-based youth in Baltimore, MD in the U.S.A. The most common youth-identified health problems included STDs, HIV/AIDS, pregnancy, depression, drug use and injuries. These correlate well with more objective health status data for the same youth. The youth spoke of environmental safety threats of violence and victimization by adults, as well as racism and sexism in their lives. Youth reported that trusted adult figures such as grandmothers are important sources of health advice. Many homeless youth from less than ideal family situations remain in contact with and continue to seek advice from parents and other family members. Health interventions with urban street youth need to acknowledge the primacy of the social context for these youth, as well as the reality of violence as a daily health threat.

    Sphingomyelin metabolism has been linked to several diseases and to longevity. However, few epidemiological studies have quantified individual plasma sphingomyelin species (identified by acyl-chain length and saturation) or their relationship between demographic factors and disease processes. In this study, we determined plasma concentrations of distinct sphingomyelin species in 992 individuals, aged 55 and older, enrolled in the Baltimore Longitudinal Study of Aging. Participants were followed, with serial measures, up to 6 visits and 38 years (3972 total samples). Quantitative analyses were performed on a high-performance liquid chromatography-coupled electrospray ionization tandem mass spectrometer. Linear mixed models were used to assess variation in specific sphingomyelin species and associations with demographics, diseases, medications or lifestyle factors, and plasma cholesterol and triglyceride levels. We found that most sphingomyelin species increased with age. Women had higher plasma levels of all sphingomyelin species and showed steeper trajectories of age-related increases compared to men. African Americans also showed higher circulating sphingomyelin concentrations compared to Caucasians. Diabetes, smoking, and plasma triglycerides were associated with lower levels of many sphingomyelins and dihydrosphingomyelins. Notably, these associations showed specificity to sphingomyelin acyl-chain length and saturation. These results demonstrate that longitudinal changes in circulating sphingomyelin levels are influenced by age, sex, race, lifestyle factors, and diseases. It will be important to further establish the intra-individual age- and sex-specific changes in each sphingomyelin species in relation to disease onset and progression. PMID:25345489

    Increasing interest in the Atlantic continental margin as a future petroleum province has resulted in several recent papers (Emmerich, 1974; Burk and Drake, 1974) that attempt to summarize the structure and stratigraphic framework of this area. Most papers tend to portray the margin as a wedge of Mesozoic and Cenozoic sediment that thins at the edge of the shelf over a "basement ridge" and then thickens again under the continental rise. Off the northeastern United States, the sediment wedge under the shelf attains a thickness of 8-11 km in the Georges Bank basin (Schultz and Glover, 1974; Mattick and others, 1974; Sheridan, 1974b; Behrendt and others, 1974) and 12 km in thickness in the Baltimore Canyon trough off the middle Atlantic states of Delaware, Maryland, Virginia and New Jersey (fig. 1). Seaward of the continental shelf and its sediment prism, Emery and Uchupi (1972, figs. 133-135) infer slump deposits (eroded in some areas) covering a buried ridge thought to extend from the Laurentian Channel to Cape Hatteras, where it splits in two. The lower slope and continental rise are inferred by Drake and later investigators to be a thick prism of deep sea sediment (turbidites, hemipelagic clays, slump deposits) overlying oceanic basement in a welt that parallels the continental edge and reaches a maximum thickness of 6 km (Emery and Uchupi, 1972, fig. 188).

    Understanding the spatial distribution of soil lead has been a focus of the Baltimore Ecosystem Study since its inception in 1997. Through multiple research projects that span spatial scales and use different methodologies, three overarching patterns have been identified: (1) soil lead concentrations often exceed state and federal regulatory limits; (2) the variability of soil lead concentrations is high; and (3) despite multiple sources and the highly heterogeneous and patchy nature of soil lead, discernable patterns do exist. Specifically, housing age, the distance to built structures, and the distance to a major roadway are strong predictors of soil lead concentrations. Understanding what drives the spatial distribution of soil lead can inform the transition of underutilized urban space into gardens and other desirable land uses while protecting human health. A framework for management is proposed that considers three factors: (1) the level of contamination; (2) the desired land use; and (3) the community's preference in implementing the desired land use. The goal of the framework is to promote dialogue and resultant policy changes that support consistent and clear regulatory guidelines for soil lead, without which urban communities will continue to be subject to the potential for lead exposure.

    Waterpipe smoking has been growing in popularity in the United States and worldwide. Most tobacco control regulations remain limited to cigarettes. Few studies have investigated waterpipe tobacco smoke exposures in a real world setting. We measured carbon monoxide (CO), particulate matter (PM)2.5, and airborne nicotine concentrations in seven waterpipe cafes in the greater Baltimore area. Area air samples were collected between two and five hours, with an average sampling duration of three hours. Waterpipe smoking behaviors were observed at each venue. Indoor air samplers for CO, PM2.5, and airborne nicotine were placed in the main seating area 1–2 m above the floor. Indoor airborne concentrations of PM2.5 and CO were markedly elevated in waterpipe cafes and exceeded concentrations that were observed in cigarette smoking bars. Air nicotine concentrations, although not as high as in venues that allow cigarette smoking, were markedly higher than in smoke-free bars and restaurants. Concentrations of PM approached occupational exposure limits and CO exceeded occupational exposure guidelines suggesting that worker protection measures need to be considered. This study adds to the literature indicating that both employees and patrons of waterpipe venues are at increased risk from complex exposures to secondhand waterpipe smoke. PMID:24736103

    As part of a 2009 revision to the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) program, the Department of Agriculture required WIC-authorized stores to stock additional varieties of healthy food. The long-term effects of this policy on access to healthy food are unknown. Using surveys conducted in 118 Baltimore City, Maryland, food stores in 2006 and 2012, we examined associations of the change in healthy food availability with store type, neighborhood demographics, and the 2009 WIC policy change. Overall, healthy food availability improved significantly between 2006 and 2012, with the greatest increases in corner stores and in census tracts with more than 60 percent black residents. On an 11-point scale measuring availability of fruit (3 points), vegetables (4 points), bread (2 points), and milk (2 points), the WIC policy change was associated with a 0.72-point increase in WIC-relevant healthy food availability, while joining WIC was associated with a 0.99-point increase. Stores that carry a limited variety of food items may be more receptive to stocking healthier food than previously thought, particularly within neighborhoods with a majority of black residents. Policies targeting healthy food availability have the potential to increase availability and decrease health disparities.

    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.

    Occupational safety researchers have increasingly recognized the important influence of social and structural factors on safety perception and behaviours in occupational settings. This qualitative study was conducted to explore the nature of the safety climate of exotic dance clubs in Baltimore, Maryland and the mechanisms through which this sexual geography informs dancers’ perceptions of safety and experience of sex work. Structured observations and semi-structured qualitative interviews (N=40) were conducted with club dancers, doormen, managers, and bartenders from May through August, 2009. Data were analyzed using an inductive approach whereby themes emerged from the data itself. Atlas-ti was used for data analysis. Perceptions of safety within exotic dance clubs were born from an interplay between the physical, social, and symbolic environments. These perceptions were closely tied to dancers’ construction of sex work inside versus outside of the club. Understanding the contextual factors, which influence how dancers understand and prioritize risk in their work settings, is crucial for creating policies and programs, which effectively reduce risk in this environment.

    Introduction Self-reported history of endodontic treatment (SRHET) has been used as a simplified method to estimate history of endodontic disease and treatment. This study aimed to quantify the validity of SRHET, as reported in the Baltimore Longitudinal Study of Aging (BLSA), as a method to: 1- identify individuals who experienced endodontic treatment (ET); and 2- identify individuals who present with apical periodontitis (AP). Methods SRHET was collected through the BLSA questionnaire in 247 participants. Data on ET and AP were determined from panoramic radiographs. The total number of ET, AP and missing teeth were recorded for each individual. Validity of SRHET was determined based on ET and AP, separately. Accuracy, efficiency, sensitivity, specificity, positive and negative predictive values (+PV, −PV) and positive and negative likelihood ratios (+LR, −LR) were calculated according to standard methods. Results After exclusions, 229 participants were available for ET analysis and 129 for AP analysis. The SRHET validity values were: sensitivity (ET=0.915; AP=0.782), specificity (ET=0.891; AP=0.689), +PV (ET=0.824; AP=0.353), −PV (ET=0.949; AP=0.936), +LR (ET=8.394; AP=2.514) and −LR (ET=0.095; AP=0.316). Conclusions SRHET was found to be a highly accurate method to predict ET but a weak predictor of the presence of AP among participants in the BLSA. PMID:22515884

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

    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.

  14. Relationships between aerodynamic roughness and land use and land cover in Baltimore, Maryland

    Urbanization changes the radiative, thermal, hydrologic, and aerodynamic properties of the Earth's surface. Knowledge of these surface characteristics, therefore, is essential to urban climate analysis. Aerodynamic or surface roughness of urban areas is not well documented, however, because of practical constraints in measuring the wind profile in the presence of large buildings. Using an empirical method designed by Lettau, and an analysis of variance of surface roughness values calculated for 324 samples averaging 0.8 hectare (ha) of land use and land cover sample in Baltimore, Md., a strong statistical relation was found between aerodynamic roughness and urban land use and land cover types. Assessment of three land use and land cover systems indicates that some of these types have significantly different surface roughness characteristics. The tests further indicate that statistically significant differences exist in estimated surface roughness values when categories (classes) from different land use and land cover classification systems are used as surrogates. A Level III extension of the U.S. Geological Survey Level II land use and land cover classification system provided the most reliable results. An evaluation of the physical association between the aerodynamic properties of land use and land cover and the surface climate by numerical simulation of the surface energy balance indicates that changes in surface roughness within the range of values typical of the Level III categories induce important changes in the surface climate.

    Animal studies have demonstrated that experimentally induced vestibular ablation leads to a decrease in bone mineral density, through mechanisms mediated by the sympathetic nervous system. Loss of bone mineral density is a common and potentially morbid condition that occurs with aging, and we sought to investigate whether vestibular loss is associated with low bone mineral density in older adults. We evaluated this question in a cross-sectional analysis of data from the Baltimore Longitudinal Study of Aging (BLSA), a large, prospective cohort study managed by the National Institute on Aging (N = 389). Vestibular function was assessed with cervical vestibular evoked myogenic potentials (cVEMPs), a measure of saccular function. Bone mineral density was assessed using dual-energy X-ray absorptiometry (DEXA). In two-way t test analysis, we observed that individuals with reduced vestibular physiologic function had significantly lower bone mineral density. In adjusted multivariate linear regression analyses, we observed that older individuals with reduced vestibular physiologic function had significantly lower bone mineral density, specifically in weight-bearing hip and lower extremity bones. These results suggest that the vestibular system may contribute to bone homeostasis in older adults, notably of the weight-bearing hip bones at greatest risk of osteoporotic fracture. Further longitudinal analysis of vestibular function and bone mineral density in humans is needed to characterize this relationship and investigate the potential confounding effect of physical activity.

    In June 1908, James Mark Baldwin, then Professor of Psychology and Philosophy at Johns Hopkins University and at the pinnacle of his career, was arrested in a Baltimore house of prostitution. Although he insisted on both his legal and moral innocence and all legal charges against him were dismissed, the threat of scandal led Hopkins authorities to demand Baldwin's resignation and Baldwin to remove himself and his family permanently to France. While this is one of the most notorious events in the early history of American psychology, almost nothing has been known about the incident itself, because both Baldwin and Hopkins took great pains to keep these details private. Based on court records, contemporary newspaper accounts, and archival materials in the Presidential Records at Hopkins and elsewhere, it is now possible to reconstruct the events of 1908 and their aftermath in detail. This article describes these occurrences; places them in the context of Baldwin's life, personality, and career; presents newly obtained information on the immediate consequences of the arrest, including circumstances leading to Baldwin's forced resignation; and describes the long-term impact of Baldwin's removal from the United States. Although no definitive conclusion with regard to Baldwin's guilt or innocence can be reached, we conclude by contrasting the treatment received at the hands of his colleagues in psychology with the lifelong support received from his wife and family, and suggest that Baldwin may have been the victim of a premature rush to judgment.

    Background We characterized patterns of highly active antiretroviral therapy (HAART) use and predictors of non-structured treatment interruptions (NTIs) among injection drug users (IDUs) in Baltimore, MD. Methods 335 IDUs who initiated HAART from 1996-2006 were studied. NTIs were defined as any subsequent six-month interval where HAART was not reported. Predictors of the first NTI and subsequent restart of HAART were examined using Cox regression. Results 260 (78%) reported ≥1 NTI. Of 215 with ≥1 follow-up visit after the NTI, 44 (20%) never restarted HAART, 62 (29%) restarted and remained on HAART and 109 (51%) reported multiple NTIs. NTIs were less likely among those who initiated HAART in later calendar years and hada recent outpatient visit and more likely among women, persons with detectable HIV RNA at the prior visit and those who reported injecting daily. Among those with NTIs, interuptions occurred earlier in persons who were younger, did not have a prior AIDS diagnosis and were actively injecting; NTIs lasted longer in persons who had higher HIV RNA levels, were incarcerated and drinking alcohol. A recent outpatient visit and not actively injecting were associated with restarting HAART. Conclusions NTIs were common in this population and occurred most frequently in the setting of active drug use and disruption of health care. Effective linkages between primary care for HIV and substance abuse treatment may improve HAART outcomes in this population. PMID:19214124

    The Baltimore Canyon Trough (BCT) and Georges Bank Basin (GBB) formed along the continental edge off the northeastern United States during early Mesozoic extensional rifting between Africa and North America and have continued to subside throughout the late Mesozoic and Cenozoic. The seaward edge of the marginal basins and the western edge of the oceanic crust are marked by the East Coast Magnetic Anomaly (ECMA), which lies between the present Outer Continental Shelf edge and the Upper Continental Rise. The landward edge of the basins is marked by a hinge zone of rotated fault blocks, where the depth to the basement increases abruptly. Sediment deposition within the two basins can be divided into synrift and postrift phases, the base of the relatively undisturbed postrift deposits being marked by a postrift unconformity (PRU). Prerift and synrift deposits (including evaporites) as much as 5 km thick can be seen below the PRU on some seismic profiles, but their base is difficult to resolve on seismic profiles, and their maximum thickness could be much greater. After sea floor spreading began, continued subsidence of the basins due to thermal cooling of the lithosphere and sediment loading resulted in the deposition of as much as 13 km of postrift sedimentary rocks in BCT and 7 km in GBB. Although the Jurassic carbonate shelf-edge system migrated 40 km seaward onto the oceanic crust off northern BCT, shelf edges have generally remained landward of the ECMA and have retreated about 10 to 20 km during the late Cenozoic.

    Medical students from University of Maryland and Johns Hopkins University, with a grant from the Maryland Chapter of the American College of Physicians, held a free health fair in a Baltimore City neighborhood. The goals were to heighten awareness of common health problems, learn more about a medically underserved community, and increase access to primary care services in that community. The students planned booths to offer information and screening on 19 common health topics. Fair organizers worked with a local clinic, People's Community Health Center, and a neighborhood development organization, the Safe and Smart Center, to create an event that would engage and educate people on relevant issues. Approximately 100 medical students participated in the event and 350 people attended the fair. An optional survey filled out by fair participants revealed that a diverse group of people attended the event. Comments about the day from medical students and fair participants show that the event was enjoyable and offered a tremendous learning opportunity for both groups. This paper also discusses problems that arose during the planning stages as well as suggestions for those interested in planning a similar event.

    The City of Baltimore, Maryland, and parts of five surrounding counties obtain their water from Loch Raven and Liberty Reservoirs. A third reservoir, Prettyboy, is used to resupply Loch Raven Reservoir. Management of the watershed conditions for each reservoir is a shared responsibility by agreement among City, County, and State jurisdictions. The most recent (2005) Baltimore Reservoir Watershed Management Agreement (RWMA) called for continued and improved water-quality monitoring in the reservoirs and selected watershed tributaries. The U.S. Geological Survey (USGS) conducted a retrospective review of the effectiveness of monitoring data obtained and analyzed by the RWMA jurisdictions from 1981 through 2007 to help identify possible improvements in the monitoring program to address RWMA water-quality concerns. Long-term water-quality concerns include eutrophication and sedimentation in the reservoirs, and elevated concentrations of (a) nutrients (nitrogen and phosphorus) being transported from the major tributaries to the reservoirs, (b) iron and manganese released from reservoir bed sediments during periods of deep-water anoxia, (c) mercury in higher trophic order game fish in the reservoirs, and (d) bacteria in selected reservoir watershed tributaries. Emerging concerns include elevated concentrations of sodium, chloride, and disinfection by-products (DBPs) in the drinking water from both supply reservoirs. Climate change and variability also could be emerging concerns, affecting seasonal patterns, annual trends, and drought occurrence, which historically have led to declines in reservoir water quality. Monitoring data increasingly have been used to support the development of water-quality models. The most recent (2006) modeling helped establish an annual sediment Total Maximum Daily Load to Loch Raven Reservoir, and instantaneous and 30-day moving average water-quality endpoints for chlorophyll-a (chl-a) and dissolved oxygen (DO) in Loch Raven and Prettyboy

    OBJECTIVE: The goal of this study was to prospectively define the impact of laparoscopy on the management of patients with a presumed diagnosis of appendicitis. SUMMARY BACKGROUND DATA: While the role of laparoscopy in the management of cholelithiasis is well established, its impact on the management of acute appendicitis needs to be objectively defined and compared to that of conventional management. Several authors have predicted that laparoscopic appendectomy will become the preferred treatment for appendicitis. METHODS: Two groups of consecutive patients with similar clinical characteristics of acute appendicitis were compared. Data on the laparoscopic group were compiled prospectively on standardized forms; data on the conventional group were collected retrospectively. Operative time, hospital stay, analgesia, cost, and return to normal activities were noted. RESULTS: Seventeen consecutive patients who underwent appendectomy were compared to 18 consecutive patients who underwent laparoscopy (16 of these 18 had laparoscopic appendectomy). There was no significant difference between the two groups in terms of clinical characteristics and appendiceal histopathology. The mean operative times were 61 +/- 4.1 minutes and 46 +/- 2.9 minutes for the laparoscopy and conventional groups, respectively (p < 0.01). Hospital stay was significantly shorter in the laparoscopic appendectomy group, with 81% of patients being discharged on their first postoperative day (p < 0.001). The laparoscopic appendectomy patients required significantly less narcotic analgesia (p < 0.02). Return to normal activity was not significantly different between the two groups. The average total cost of laparoscopic appendectomy was 30% greater than that of conventional appendectomy. CONCLUSIONS: Laparoscopy is a useful adjunct to the management of patients with a presumed clinical diagnosis of acute appendicitis. PMID:8239785

    Testing and linkage to care are important determinants of hepatitis C virus (HCV) treatment effectiveness. Public health clinics serve populations at high risk of HCV. We investigated their potential to serve as sites for HCV testing, initiation of and linkage to HCV care. Cross-sectional study of patients accessing sexually transmitted infection (STI) care at the Baltimore City Health Department (BCHD) STI clinics, from June 2013 through April 2014 was conducted. Logistic regression was used to assess factors associated with HCV infection and specialist linkage to care. Between 24 June 2013 and 15 April 2014, 2681 patients were screened for HCV infection. Overall, 189 (7%) were anti-HCV positive, of whom 185 (98%) received follow-up HCV RNA testing, with 155 (84%) testing RNA positive. Of 155 RNA-positive individuals, 138 (89%) returned to the STI clinic for HCV RNA results and initial HCV care including counselling regarding transmission and harm reduction in alcohol, and 132 (85%) were referred to a specialist for HCV care. With provision of patient navigation services, 81 (52%) attended an offsite HCV specialist appointment. Alcohol use and lack of insurance coverage were associated with lower rates of specialist linkage (OR 0.4 [95% CI 0.1-0.9] and OR 0.4 [95% CI 0.1-0.9], respectively). We identified a high prevalence of HCV infection in BCHD STI clinics. With availability of patient navigation services, a large proportion of HCV-infected patients linked to off-site specialist care.

    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.

    Background: poor cognitive and motor performance predicts neurological dysfunction. Variable performance may be a subclinical indicator of emerging neurological problems. Objective: examine the cross-sectional association between a clinically accessible measure of variable walking and executive function. Methods: older adults aged 60 or older from the Baltimore Longitudinal Study of Aging (n = 811) with data on the 400-m walk test and cognition. Based on ten 40-m laps, we calculated mean lap time (MLT) and variation in time across ten 40-m laps (lap time variation, LTV). Executive function tests assessed attention and short-term memory (digit span forward and backward), psychomotor speed [Trail Making Test (TMT) part A] and multicomponent tasks requiring cognitive flexibility [TMT part B, part B-A (Delta TMT) and digit symbol substitution test (DSST)]. Multivariate linear regression analysis examined the cross-sectional association between LTV and executive function, adjusted for MLT, age, sex and education, as well as the LTV × MLT interaction. Results: the LTV was univariately associated with all executive function tests except digit span (P < 0.001); after adjustment, the association with TMT part A remained (standardised β = 0.142, P = 0.002). There was an interaction between MLT and LTV; among fast walkers, greater LTV was associated with a greater Delta TMT (β for LTV × MLT = −1.121, P = 0.016) after adjustment. Conclusion: at any walking speed, greater LTV is associated with psychomotor slowing. Among persons with faster walking speed, variation is associated with worse performance on a complex measure of cognitive flexibility. A simple measure of variability in walking time is independently associated with psychomotor slowing. PMID:26082177

    OBJECTIVES To investigate the relationship between vestibular loss associated with aging and age-related decline in visuospatial function. DESIGN Cross-sectional analysis within a prospective cohort study. SETTING Baltimore Longitudinal Study of Aging (BLSA). PARTICIPANTS Community-dwelling BLSA participants with a mean age of 72 (range 26–91) (N = 183). MEASUREMENTS Vestibular function was measured using vestibular-evoked myogenic potentials. Visuospatial cognitive tests included Card Rotations, Purdue Pegboard, Benton Visual Retention Test, and Trail-Making Test Parts A and B. Tests of executive function, memory, and attention were also considered. RESULTS Participants underwent vestibular and cognitive function testing. In multiple linear regression analyses, poorer vestibular function was associated with poorer performance on Card Rotations (P = .001), Purdue Pegboard (P = .005), Benton Visual Retention Test (P = 0.008), and Trail-Making Test Part B (P = .04). Performance on tests of executive function and verbal memory were not significantly associated with vestibular function. Exploratory factor analyses in a subgroup of participants who underwent all cognitive tests identified three latent cognitive abilities: visuospatial ability, verbal memory, and working memory and attention. Vestibular loss was significantly associated with lower visuospatial and working memory and attention factor scores. CONCLUSION Significant consistent associations between vestibular function and tests of visuospatial ability were observed in a sample of community-dwelling adults. Impairment in visuospatial skills is often one of the first signs of dementia and Alzheimer’s disease. Further longitudinal studies are needed to evaluate whether the relationship between vestibular function and visuospatial ability is causal. PMID:26311169

    Since the release of the first Surgeon General's report, the proportion of adult smokers in the U.S. has been reduced by half (U.S. Department of Health and Human Services, 2004). This success has not, however, been equally felt across all social strata. Recent survey data from Baltimore show considerably elevated smoking rates within urban, African-American communities. Of particular concern was that in some communities, over half of the young adults (18-24 years old) smoke cigarettes. As yet, there has been little focus on understanding or preventing cigarette smoking among young adults, particularly for those seeking entry into the workforce rather than being engaged in higher education. In this paper, we explore community factors contributing to high young adult smoking prevalence. Our analysis is based on data from four focus groups conducted in 2004 as part of a community-based participatory research project with two urban education and job training organizations. The focus group data reflect the experiences and opinions of 28 young adult program participants (23 smokers and 5 nonsmokers). The data highlight a normalized practice of buying and selling single cigarettes ("loosies") within the community, with participants describing buying loose cigarettes as a preferred acquisition practice. We apply theories of informal economy and suggest that this alternative purchasing option may influence the smoking behavior of these young adults. We argue that public health efforts need to more closely consider the impact of community structures on program implementation. Overlooking key community characteristics such as the availability of single cigarettes may serve to intensify health disparities.

    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

    We investigate storm event hydrologic response across an array of urban basins through analyses of high-resolution hydrologic observations and numerical experimentation using a watershed model. Nine similarly sized (approximately 10 sq km) basins were chosen in the Baltimore metropolitan area. The basins range from Baisman Run, a forested control basin, to Moores Run, the flashiest basin in the contiguous United States (Smith et al. 2005 J. of Hydroclimatology). Analyses were carried out using high resolution discharge data (1- to 5-min from USGS) and rainfall radar data (1-km and 15-min, processed through Hydro-NEXRAD and bias corrected) for a ten-year period from 2000-2009. The fifty largest storm events were chosen for each basin using a peak over threshold approach to examine the following: variation in hydrologic response timescales, variation in response magnitude, variation of storm event type, clustering of storm events, effects of storm water infrastructure, and effects of impervious surfaces. Analyses point to the possible importance of soils and storage within the urban basin. Some questions - such as the role of antecedent moisture in urban hydrologic response - cannot be fully answered through analyses of available rainfall and discharge data. A watershed model for the Dead Run basin is being created to examine these questions. The Dead Run model is created using the Gridded Surface/ Subsurface Hydraulic Analysis (GSSHA) model from the Army Corps of Engineers. GSSHA is a physically-based, gridded model with 2-D overland flow and 1-D stream flow and infiltration processes. Results of numerical experiments using the Dead Run model will be presented to provide insight into the role of urban soils and elaboration of the drainage network through the strorm drain network for storm event hydrologic response.

    Objective Depression is increasingly recognized as a risk factor for type 2 diabetes, and is also commonly comorbid with anxiety. However, few studies have examined whether anxiety is predictive of diabetes risk. The objectives of this study are to examine the prospective relationship between anxiety disorders (generalized anxiety disorder, panic disorder, social phobia, and agoraphobia) and risk of type 2 diabetes over an 11-year period, and to investigate the association between anxiety and risk of diabetes-related complications among those with prevalent type 2 diabetes. Methods Data come from the 1993/6 and 2004/5 waves of the Baltimore Epidemiologic Catchment Area Study (N=1920), a population-based prospective cohort. Anxiety disorders were assessed using the Diagnostic Interview Schedule. The prospective association between anxiety and incident type 2 diabetes was evaluated using a series of nested multivariable logistic regression models. Results At baseline, 315 participants (21.8%) had an anxiety disorder. The relationship between anxiety and risk of developing type 2 diabetes was not statistically significant after controlling for demographic characteristics (Odds Ratio (OR): 1.28, 95% Confidence Interval (CI): 0.75, 2.18). There was no relationship between anxiety and diabetes risk after controlling for health behaviors and depression status (OR: 1.00, 95% CI: 0.53, 1.89). There was no significant relationship between anxiety and development of diabetes-related complications among those with prevalent type 2 diabetes (OR: 2.02, 95% CI: 0.61, 6.74). Conclusion Anxiety disorders are not associated with increased risk of type 2 diabetes or risk of diabetes complications among those who have diabetes in the present study. PMID:23148808

    The contribution of streams and rivers to the carbon cycle is significant, transporting to the oceans ~1.4 Pg C/yr, with dissolved carbon corresponding to as much as 0.7 Pg C/yr. Changes in land use have the potential effect of modifying this flux, particularly in urban areas where impervious areas are common. To investigate the effect of urbanization on riverine carbon transport, we studied four first-order streams in Towson, a suburb of Baltimore, Maryland, USA. The watersheds from the studied streams exhibit different levels of urbanization as measured by the percentage of impervious areas. Samples from these four streams were taken weekly, and several chemical constituents were measured either in the field or in the laboratory. These constituents included nitrate, dissolved organic nitrogen, pH, dissolved organic carbon (DOC), total carbon, dissolved inorganic carbon (DIC), phosphate, the carbon isotopic compositions of DOC and DIC, and fluorescence intensity of the DOC. Results show that DOC concentrations were consistently below 5 mg C/L regardless of the level of imperviousness of the watershed. Similarly, carbon isotope ratios were consistent across the studied streams, with values centered around -26.4 per mil, thus suggesting a significant influx of soil-derived organic carbon originated from C3 plants that are common in the watersheds. Confirming this interpretation, fluorescence spectroscopy data suggest a humic-like origin for the DOC of the streams, thus pointing to the heterotrophic nature of the streams. The combined results suggest that the studied streams exhibit similar DOC concentrations, carbon isotopic values, and fluorescence spectra, despite their level of impervious surfaces in their watersheds.

    In the drug field the fundamental epidemiological question-why illicit drug use, here, now, among these people-has still not been adequately answered. Drawing on the work of colleagues in medical anthropology, we attempt to move closer to an answer by developing a "trend theory." In this article we analyze a single case: the increase in heroin use and addiction among African Americans in the City of Baltimore in the 1960s. We found that the two most important historical processes behind the epidemic were (1) a changing distribution/supply system and (2) the mix of hope and despair that was part of the early civil rights movement.

Air quality and meteorological data were collected from the eight monitors that constitute the Baltimore forecast region. These data were used to build the ESP using a moving-block bootstrap, regression tree models, and extreme-value theory. The ESP was evaluated using a 10-fold cross-validation to avoid evaluation with the same data used in the development process. Results indicate that the ESP is conditionally biased, likely due to slight overfitting while training the regression tree models. When viewed from the perspective of a decision-maker, the ESP provides a wealth of additional information previously not available through the NAQFC alone. The user is provided the freedom to tailor the forecast to the decision at hand by using decision-specific probability thresholds that define a forecast for an ozone exceedance.

    Background Despite longstanding controversies from animal studies on the relationship between basal metabolic rate (BMR) and longevity, whether BMR is a risk factor for mortality has never been tested in humans. We evaluate the longitudinal changes in BMR and the relationship between BMR and mortality in the Baltimore Longitudinal Study of Aging (BLSA) participants. Methods BMR and medical information were collected at the study entry and approximately every 2 years in 1227 participants (972 men) over a 40-year follow-up. BMR, expressed as kcal/m2/h, was estimated from the basal O2 consumption and CO2 production measured by open-circuit method. Data on all-cause and specific-cause mortality were also obtained. Result BMR declined with age at a rate that accelerated at older ages. Independent of age, participants who died had a higher BMR compared to those who survived. BMR was a significant risk factor for mortality independent of secular trends in mortality and other well-recognized risk factors for mortality, such as age, body mass index, smoking, white blood cell count, and diabetes. BMR was nonlinearly associated with mortality. The lowest mortality rate was found in the BMR range 31.3–33.9 kcal/m2/h. Participants with BMR in the range 33.9–36.4 kcal/m2/h and above the threshold of 36.4 kcal/m2/h experienced 28% (hazard ratio: 1.28; 95% confidence interval, 1.02–1.61) and 53% (hazard ratio: 1.53; 95% confidence interval, 1.19–1.96) higher mortality risk compared to participants with BMR 31.3–33.9 kcal/m2/h. Conclusion We confirm previous findings of an age-related decline of BMR. In our study, a blunted age-related decline in BMR was associated with higher mortality, suggesting that such condition reflects poor health status. PMID:18693224

    Among youth 15 to 24 years of age, homicide and nonfatal shootings are the leading causes of mortality and morbidity. Urban youth's attitudes and perceptions about the use of gun violence to resolve conflict present a major barrier to efforts to reduce gun homicides and nonfatal shootings. The current investigation extends the existing literature on attitudes toward guns and shootings among high-risk youth ages 18 to 24 by measuring perceived norms and viewpoints regarding gun violence in two analogous Baltimore City neighborhoods pre-implementation and 1-year post-implementation of the Safe Streets intervention (adapted from the CeaseFire/Cure Violence intervention). The Safe Streets intervention is designed for communities with high rates of gun violence and utilizes outreach workers to identify and build trusting relationships with youth ages 15 to 24 who are at greatest risk of being involved in gun violence. The outreach workers also position themselves in the community so that they can rapidly intervene in disputes that have the potential to lead to gun violence. Chi-squared tests and exploratory structural equation modeling (ESEM) were used to examine changes in attitudes toward gun violence 1 year after the implementation of the Safe Streets intervention. There was a statistically significantly improvement in 43 % of the attitudes assessed in the intervention community post-intervention compared to 13 % of the attitudes in the control community. There was a statistically significant improvement in the violent attitudes toward personal conflict resolution scale after implementation of the intervention in both the intervention (b = -0.522, p < 0.001) and control community (b = -0.204, p < 0.032). Exposure to the intervention (e.g., seeing stop shooting signs in your neighborhood) was also associated with the nonviolent attitudes toward conflict scale.

Testing and diagnosis are important first steps in receiving treatment and reducing transmission. We analyzed cross-sectional data collected in 2004-2005, 2008, and 2011 among MSM not reporting a previous positive HIV test (n = 1268) in Baltimore, Maryland as part of the National HIV Behavioral Surveillance System to determine the proportion of men tested for HIV and/or syphilis within the previous 12 months and examine the extent to which opportunities for testing were being missed in health care settings. Within the previous 12 months, 54 % of men had received an HIV test; 31 % had received a syphilis test; and only 23 % of men had received testing for both. Among 979 men who did not receive both tests, 72 % had seen a health care provider in the past year, suggesting missed testing opportunities.

    Poor accessibility to affordable healthy foods is associated with higher rates of obesity and diet-related chronic diseases. We present our process evaluation of a youth-targeted environmental intervention (Baltimore Healthy Eating Zones) that aimed to increase the availability of healthy foods and promote these foods through signage, taste tests and other interactive activities in low-income Baltimore City. Trained peer educators reinforced program messages. Dose, fidelity and reach-as measured by food stocking, posting of print materials, distribution of giveaways and number of interactions with community members-were collected in six recreation centers and 21 nearby corner stores and carryouts. Participating stores stocked promoted foods and promotional print materials with moderate fidelity. Interactive sessions were implemented with high reach and dose among both adults and youth aged 10-14 years, with more than 4000 interactions. Recreation centers appear to be a promising location to interact with low-income youth and reinforce exposure to messages. PMID:23766452

    The provision of mechanical ventilation for the support of infants and children with respiratory failure or insufficiency is one of the most common techniques that are performed in the Pediatric Intensive Care Unit (PICU). Despite its widespread application in the PICUs of the 21st century, before the 1930s, respiratory failure was uniformly fatal due to the lack of equipment and techniques for airway management and ventilatory support. The operating rooms of the 1950s and 1960s provided the arena for the development of the manual skills and the refinement of the equipment needed for airway management, which subsequently led to the more widespread use of endotracheal intubation thereby ushering in the era of positive pressure ventilation. Although there seems to be an ever increasing complexity in the techniques of mechanical ventilation, its successful use in the PICU should be guided by the basic principles of gas exchange and the physiology of respiratory function. With an understanding of these key concepts and the use of basic concepts of mechanical ventilation, this technique can be successfully applied in both the PICU and the operating room. This article reviews the basic physiology of gas exchange, principles of pulmonary physiology, and the concepts of mechanical ventilation to provide an overview of the knowledge required for the provision of conventional mechanical ventilation in various clinical arenas.

    In this research, the mathematical models, indicating the capability of various units, such as rapid mixing, coagulation and flocculation, sedimentation, and the rapid sand filtration are used. Moreover, cost functions were used for the formulation of conventional water and wastewater treatment plant by applying Clark's formula (Clark, 1982). Also, by applying dynamic programming algorithm, it is easy to design a conventional treatment system with minimal cost. The application of the model for a case reduced the annual cost. This reduction was approximately in the range of 4.5-9.5% considering variable limitations. Sensitivity analysis and prediction of system's feedbacks were performed for different alterations in proportion from parameters optimized amounts. The results indicated (1) that the objective function is more sensitive to design flow rate (Q), (2) the variations in the alum dosage (A), and (3) the sand filter head loss (H). Increasing the inflow by 20%, the total annual cost would increase to about 12.6%, while 20% reduction in inflow leads to 15.2% decrease in the total annual cost. Similarly, 20% increase in alum dosage causes 7.1% increase in the total annual cost, while 20% decrease results in 7.9% decrease in the total annual cost. Furthermore, the pressure decrease causes 2.95 and 3.39% increase and decrease in total annual cost of treatment plants.

    Rodlets, occurring in shale and coal (uppermost Berriasian to middle Aptian, Lower Cretaceous), were identified from drill cuttings taken from depths between 9330 ft (2844 m) and 11, 460 ft (3493 m) in the Texaco et al., Federal Block 598, No. 2 well, in the Baltimore Canyon Trough. Under the binocular microscope, most of the rodlets appear black, but a few are reddish brown, or brownish and translucent on thin edges. They range in diameter from about 0.4 to 1.7 mm and are commonly flattened. The rodlets break with a conchoidal fracture, and some show an apparent cellular cast on their longitudinal surfaces. When polished and viewed in reflected light, the rodlets appear dark gray and have an average random reflectance of less than 0.1% whereas mean maximum reflectances are 0.48-0.55% for vitrinite in the associated shale and coal. These vitrinite reflectances indicate either subbituminous A or high-volatile C bituminous coal. The rodlets fluoresce dull gray yellow to dull yellow. The scanning electron microscope (SEM) and light microscope reveal the presence of swirl-like features in the rodlet interiors. Minerals associated with the rodlets occur as sand-size grains attached to the outer surface, as finely disseminated interior grains, and as fracture fillings. Electron microprobe and SEM-energy-dispersive X-ray (EDX) anlayses indicate that the minerals are dominantly clays (probably illite and chlorite) and iron disulfide; calcium carbonate, silicon dioxide, potassium aluminum silicate (feldspar), titanium dioxide, zinc sulfide, and iron sulfate minerals have been also identified. The rodlets were analyzed directly for C, H, N, O, and total S and are interpreted as true resins on the basis of C and H contents that range from 75.6 to 80.3 and from 7.4 to 8.7 wt. % (dry, ash-free basis), respectively. Elemental and infrared data support a composition similar to that of resinite from bituminous coal. Elements determined to be organically associated in the rodlets

    In order to utilize satellite-based aerosol measurements for the determination of air quality, the relationship between aerosol optical properties (wavelength-dependent, column-integrated extinction measured by satellites) and mass measurements of aerosol loading (PM2.5 used for air quality monitoring) must be understood. This connection varies with many factors including those specific to the aerosol type, such as composition, size and hygroscopicity, and to the surrounding atmosphere, such as temperature, relative humidity (RH) and altitude, all of which can vary spatially and temporally. During the DISCOVER-AQ (Deriving Information on Surface conditions from Column and Vertically Resolved Observations Relevant to Air Quality) project, extensive in-situ atmospheric profiling in the Baltimore, MD-Washington, DC region was performed during fourteen flights in July 2011. Identical flight plans and profile locations throughout the project provide meaningful statistics for determining the variability in and correlations between aerosol loading, composition, optical properties and meteorological conditions. Measured water-soluble aerosol mass was composed primarily of ammonium sulfate (campaign average of 32 %) and organics (57 %). A distinct difference in composition was observed with high-loading days having a proportionally larger percentage of ammonium sulfate (up to 49 %) due to transport from the Ohio River Valley. This composition shift caused a change in the aerosol water-uptake potential (hygroscopicity) such that higher relative contributions of ammonium sulfate increased the bulk aerosol hygroscopicity. These days also tended to have higher relative humidity causing an increase in the water content of the aerosol. Conversely, low aerosol loading days had lower ammonium sulfate and higher black carbon contributions causing lower single scattering albedos (SSAs). The average black carbon concentrations were 240 ng m-3 in the lowest 1 km decreasing to 35 ng m-3

  18. "A startling new chemotherapeutic agent": pediatric infectious disease and the introduction of sulfonamides at Baltimore's Sydenham Hospital.

    Connolly, Cynthia; Golden, Janet; Schneider, Benjamin

    2012-01-01

    Using pediatric patient records from Baltimore's Sydenham Hospital, this article explores the adoption of sulfa drugs in pediatrics. It discusses how clinicians dealt with questions of dosing and side effects and the impact of the sulfonamides on two diagnoses in children: meningococcal meningitis and pneumonia. The care of infants and children with infectious diseases made demands on physicians and nurses that differed from those facing clinicians treating adult patients. The article demonstrates the need to distinguish between pediatric and adult medical history. It suggests that the new therapeutics demanded more intense bedside care and enhanced laboratory facilities, and as a result paved the way for the adoption of penicillin. Finally, it argues that patient records and the published medical literature must be examined together in order to gain a full understanding of how transformations in medical practice and therapeutics occur.

    1996-12-31

    On December 18, 1991, the City of Baltimore contracted with Wheelabrator Clean Water Systems Inc. (WCWS) (formerly Bio Gro Systems Inc.) for the construction and operation of a 54.8 dry tons per day (dtpd) biosolids dryer/pelletizer facility. The plant has been constructed at the Back River Wastewater Treatment Plant (BRWWTP) in Essex, Maryland and is in the first year of a 20-year operating contract. The facility is the largest indirect biosolids dryer facility in the world and the first of its type in North America. This paper discusses the development of the project and several of the key start-up issues that resulted in successful commercial operation by the end of 1994. Also, some process equipment difficulties that were experienced during start-up and resulting system modifications are reviewed.

    1987-01-01

    Low altitude, oblique and vertical color photography taken from EPA's Enviro-Pod Ka 85 camera system has provided the data for taking an inventory of building surface materials in a test area of downtown Baltimore. Photography was acquired from a gridded flight plan to provide views of all sides of buildings. Color, texture, and linear detail are employed in the photo interpretation aided by contextual reference to a classification of building construction type developed in an earlier study. The work could potentially support a materials inventory initiated by the National Acid Precipitation Assessment Program (NAPAP) by scientists from EPA, Geological Survey, and the Department of Energy. Initial results show the method to be viable. Discrete surface materials such as brick, both bare and painted, stone, and metal are identified.

    Objectives. To investigate whether sensory function declines independently or in parallel with age within a single individual. Methods. Cross-sectional analysis of Baltimore Longitudinal Study of Aging (BLSA) participants who underwent vision (visual acuity threshold), proprioception (ankle joint proprioceptive threshold), vestibular function (cervical vestibular-evoked myogenic potential), hearing (pure-tone average audiometric threshold), and Health ABC physical performance battery testing. Results. A total of 276 participants (mean age 70 years, range 26–93) underwent all four sensory tests. The function of all four systems declined with age. After age adjustment, there were no significant associations between sensory systems. Among 70–79-year-olds, dual or triple sensory impairment was associated with poorer physical performance. Discussion. Our findings suggest that beyond the common mechanism of aging, other distinct (nonshared) etiologic mechanisms may contribute to decline in each sensory system. Multiple sensory impairments influence physical performance among individuals in middle old-age (age 70–79). PMID:27774319

    Nearly fifteen years after the Council of Europe first called for a pan-European convention on issues in bioethics to harmonize disparate national regulations, in November 1996 the council's Committee of Ministers approved the Convention on Human Rights and Biomedicine for formal adoption. The draft convention, released in July 1994, provoked strong public, professional, and governmental debate among European nations, particularly regarding provisions for biomedical research with subjects unable to give informed consent. If ratified, the "bioethics convention" will become the first such document to have binding force internationally.

    Much progress has been made in creating satellite products for tracking the pollutants ozone and NO2 in the troposphere. Yet, in mid-latitude regions where meteorological interactions with pollutants are complex, accuracy can be difficult to achieve, largely due to persistent layering of some constituents. We characterize the layering of ozone soundings and related species measured from aircraft over two ground sites in suburban Washington, DC (Beltsville, MD, 39.05N; 76.9W) and Baltimore (Edgewood, MD, 39.4N; 76.3W) during the July 2011 DISCOVER-AQ (Deriving Information on Surface Conditions from Column and Vertically Resolved Observations Relevant to Air Quality) experiment. First, we compare column-ozone amounts from the Beltsville and Edgewood sondes with data from overpassing satellites. Second, processes influencing ozone profile structure are analyzed using Laminar Identification and tracers: sonde water vapor, aircraft CO and NOy. Third, Beltsville ozone profiles and meteorological influences in July 2011 are compared to those from the summers of 2006-2010. Sonde-satellite offsets in total ozone during July 2011 at Edgewood and Beltsville, compared to the Ozone Monitoring Instrument (OMI), were 3 percent mean absolute error, not statistically significant. The disagreement between an OMIMicrowave Limb Sounder-based tropospheric ozone column and the sonde averaged 10 percent at both sites, with the sonde usually greater than the satellite. Laminar Identification (LID), that distinguishes ozone segments influenced by convective and advective transport, reveals that on days when both stations launched ozonesondes, vertical mixing was stronger at Edgewood. Approximately half the lower free troposphere sonde profiles have very dry laminae, with coincident aircraft spirals displaying low CO (80-110 ppbv), suggesting stratospheric influence. Ozone budgets at Beltsville in July 2011, determined with LID, as well as standard meteorological indicators, resemble those

  4. Concentration, distribution, and bioavailability of mercury and methylmercury in sediments of Baltimore Harbor and Chesapeake Bay, Maryland, USA

    For the Chesapeake Bay, sediments in regions such as Baltimore Harbor have total mercury (Hg) concentrations that exceed environmental effects guidelines. However, fish concentrations do not appear elevated. Indeed, the factors controlling the transfer of sedimentary Hg, especially as monomethylmercury (MMHg), the most bioaccumulative form of Hg, to these aquatic organisms are poorly understood. To examine this, the authors have investigated the distribution and bioavailability of Hg and MMHg to benthic organisms in Baltimore harbor and the Chesapeake Bay, in Maryland, USA. The results discussed here show that sediment concentration for both total Hg and MMHg covaries with sediment organic content and that this parameter is a better predictor, for surface sediments, of concentration than iron content, acid volatile sulfide (AVS), or other factors. Furthermore, correlations between inorganic Hg and MMHg in benthic biota with sediment levels suggest that variation in the bioaccumulation factor (SBAF) for invertebrates is best explained in terms of sediment organic content. thus, the results from this study emphasize the importance of organic matter in regions removed from point source input in controlling both the concentration and bioavailability of MMHg to organisms. Because of the exponential nature of the SBAF/organic content relationship, there is a nonlinear organism response to MMHg in sediments that must be considered in any estimation of the toxic effect of sediment MMHg. Also, as a result of the decoupling between total Hg and MMHg concentration and bioavailability in surface sediments, any remediation evaluation of bioavailability and/or toxicity that is based only on total Hg concentration is unlikely to provide a reliable prediction.

    The competitive outlook for geothermal and solar heating changed dramatically during the past year. With the recent sharp price increases in imported oil and natural gas and the planned decontrol of domestic prices, geothermal and solar energy will become competitive for space heating throughout most of the country. Under these new conditions, geothermal energy could competitively provide about 40% of the national demand for space heat and domestic hot water (about 7 quads based on 1980 demands). Nearly all of the geothermal energy demand would be in high-population-density areas. Solar energy could competitively provide about 50% (about 9 quads) of the annual demand. Most of the solar energy demand would be concentrated in suburban and rural areas. Conventional energy should remain competitive for about 30% (about 5 quads) of the annual demand. Conventional energy demand would be concentrated in the South and as supplemental energy for solar/conventional systems. Geothermal, solar, and conventional energy would be equally competitive for about 20% of the annual demand, which is why the individual market shares add to 120%.

    A needs assessment funded by the Center of Substance Abuse Prevention was conducted in 2005-2006 to determine the HIV/AIDS, substance abuse, and hepatitis prevention needs of Native Americans living in Baltimore, Maryland. We used a community-based participatory approach to gain an in-depth understanding of local Native American health service needs. Community stakeholders and key informants embedded in the local Native American population were consulted at each stage of the research planning process. Two complementary methodologies (focus groups and surveys) produced a holistic assessment of the population's needs, risks, and strengths and uncovered the social and cultural contexts in which health risk behaviors unfold. The use of these methods within a participatory framework produced a more complete portrait of the service needs of the Native American population in Baltimore. Findings from this study support the necessity for future HIV/AIDS, substance abuse, and hepatitis prevention programming for urban Native Americans. PMID:18190277

    The nonlinearity of ozone production has important policy implications as cities continue to decrease NOx, CO, and other important ozone precursors. Observations in the Baltimore/Washington area from 1970 through 2014 demonstrate reductions in NOx and CO emissions due to policy implementation leading to dramatic improvement in air quality. We will analyze the response of the reactivity of ozone, NOx, and VOC to these emission reductions in the Baltimore/Washington area using the University of Washington Chemical Model (UWCMv2.2). This model allows us to evaluate this response using multiple gas-phase chemical mechanisms. With this model, we will also compare and contrast the response of modeled ozone to reduced NOx and CO concentrations across multiple chemical mechanisms.

    Chapelle, Francis H.; with a section compiled by Kean, Tracey M.

    1985-01-01

    This study was made to develop information on the hydrogeology and ground-water geochemistry of the Patuxent and Patapsco aquifers (Lower Cretaceous) near Baltimore, Maryland. This information is needed to evaluate the availability and chemical quality of water from these aquifers. The Patuxent aquifer unconformably overlies Lower Paleozoic and Precambrian basement rocks and consists primarily of medium- to coarse-grained quartz sand. Discontinuous lenses of gravel and silty clay are commonly interbedded with the sand-sized material. The Patuxent aquifer in this area attains a thickness of 250 feet and transmissivities range from 2,000 to 8,000 feet squared per day. The Patuxent is the most productive source of ground water in the Baltimore area. In 1982, approximately 11 million gallons of water per day was produced from this unit. Several cones of depression, ranging from 30 to 50 feet below sea level, have developed in response to this pumping stress. The Arundel Formation conformably overlies the Patuxent aquifer. The Arundel is composed predominantly of clay and ranges from 0 to 150 feet thick. The Arundel exhibits very low vertical hydraulic conductivities that are on the order of 10-9 to 10-11 feet per second. This unit acts as the upper confining bed of the Patuxent aquifer in much of the project area. The Patapsco aquifer unconformably overlies the Arundel Formation and is a medium- to fine-grained quartz sand. The Patapsco functions as a water-table aquifer in much of the project area. Although the Patapsco has been heavily pumped in the past, pumpage from that aquifer in Baltimore was negligible in 1982. Brackish-water contamination of the Patuxent and Patapsco aquifers has been a major water-quality problem since the early 1900's. The Patuxent aquifer presently (1982) contains a circular plume of brackish-water contamination about 5 miles in diameter. This plume is centered on the Harbor district and has enlarged measurably since 1945. The Patapsco

    This presentation reports initial results from analysis of data collected at a set of six stream gages representing three nested watershed scales (1-2 km2, 5-6 km2, 14 km2) in Dead Run, a highly impervious suburban watershed in Baltimore County, MD, USA. Streamflow data collected at 5-minute temporal resolution during the period 2007-2011 are compared with 1-km2 gridded and watershed-average precipitation data with 15-minute temporal resolution provided by the HydroNEXRAD project for the Baltimore metropolitan area. The period of overlapping precipitation and runoff data currently available for all six nested watersheds includes calendar years 2008 and 2009. Analyses include mass balance for monthly time periods as well as individual storm events; comparison of hydrologic response among nested watersheds of similar scale and across scales; and characterization of spatial and temporal patterns in storm-period rainfall, drainage network structure, watershed morphometry, and urban infrastructure as potential influences on patterns of hydrologic response. We attempted to isolate the effects of watershed characteristics by selecting a subset of storm events with a rainfall "pulse" defined by minimum accumulation of ~10 mm and >80% of storm-total rainfall arriving within a one-hour period at all six nested subwatersheds. Hydrographs were compared to assess characteristic shape, runoff ratio, and timing. We also examined several longer, more complex storm events with multiple rainfall pulses in order to observe the response at multiple watershed scales. Despite the constraints imposed on storm structure we find that even slight variations in the spatial and temporal distribution of rainfall may be associated with major differences in watershed response (volume and timing) at the 1-2 km2 and 5-6 km2 scales. Some of these variations would be difficult to explain without availability of high-resolution rainfall data. In multiple events we observe that the 5-6 km2 watersheds

    Floating point multiplication is a critical part in high dynamic range and computational intensive digital signal processing applications which require high precision and low power. This paper presents the design of an IEEE 754 single precision floating point multiplier using asynchronous NULL convention logic paradigm. Rounding has not been implemented to suit high precision applications. The novelty of the research is that it is the first ever NULL convention logic multiplier, designed to perform floating point multiplication. The proposed multiplier offers substantial decrease in power consumption when compared with its synchronous version. Performance attributes of the NULL convention logic floating point multiplier, obtained from Xilinx simulation and Cadence, are compared with its equivalent synchronous implementation. PMID:25879069

    Soaring obesity rates in the United States demand comprehensive health intervention strategies that simultaneously address dietary patterns, physical activity, psychosocial factors and the food environment. Healthy Bodies, Healthy Souls (HBHS) is a church-based, community-participatory, cluster-randomized health intervention trial conducted in Baltimore City to reduce diabetes risk among urban African Americans by promoting healthy dietary intake, increased physical activity and improvement to the church food environment. HBHS was organized into five 3-8-week phases: Healthy Beverages, Healthy Desserts, Healthy Cooking, Healthy Snacking and Eating Out and Physical Activity. A three-part process evaluation was adopted to evaluate implementation success: an in-church instrument to assess the reach, dose delivered and fidelity of interactive sessions; a post-intervention exposure survey to assess individual-level dose received in a sample of congregants and an evaluation form to assess the church food environment. Print materials were implemented with moderate to high fidelity and high dose. Program reach was low, which may reflect inaccuracies in church attendance rather than study implementation issues. Intervention components with the greatest dose received were giveaways (42.0-61.7%), followed by taste tests (48.7-53.7%) and posters (34.3-65.0%). The dose received of general program information was moderate to high. The results indicate successful implementation of the HBHS program. PMID:23525780

    Objectives. We piloted a monitoring mechanism to document police encounters around programs targeting people who inject drugs (PWID), and assessed their demographic predictors at 2 Baltimore, Maryland, needle exchange program (NEP) sites. Methods. In a brief survey, 308 clients quantified, characterized, and sited recent police encounters. Multivariate linear regression determined encounter predictors, and we used geocoordinate maps to illustrate clusters. Results. Within the past 6 months, clients reported a median of 3 stops near NEP sites (interquartile range [IQR] = 0–7.5) and a median of 1 arrest in any location (IQR = 0–2). Three respondents reported police referral to the NEP. Being younger (P = .009), being male (P = .033), and making frequent NEP visits (P = .02) were associated with reported police stops. Among clients reporting arrest or citation for syringe possession, Whites were significantly less likely than non-Whites to report being en route to or from an NEP (P < .001). Reported encounters were clustered around NEPs. Conclusions. Systematic surveillance of structural determinants of health for PWID proved feasible when integrated into service activities. Improved monitoring is critical to informing interventions to align policing with public health, especially among groups subject to disproportionate levels of drug law enforcement. PMID:26180948

    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.

    Objectives Past studies have shown that many individuals who use antidepressants do not have a current or lifetime history of mental disorders. However, recent studies suggest that the one-time retrospective evaluation of mental disorders commonly used in such studies may substantially underestimate the true lifetime prevalence of mental disorders. We examined the prevalence of mental disorders, assessed prospectively over multiple interviews, among individuals currently using antidepressants in a community sample. Methods Using data from the Baltimore Epidemiologic Catchment Area (ECA) Survey Wave 1 (1981) through Wave 4 (2004) (N = 1071), we assessed lifetime prevalence of common mood and anxiety disorders according to the DSM-III and DSM-III-R criteria, based on 4 interviews, among participants who reported current antidepressant use. Furthermore, we examined factors associated with current antidepressant use. Results Thirteen percent of participants at Wave 4 reported currently using antidepressant medications. Among antidepressant users, 69% never met criteria for major depressive disorder (MDD), and 38% never met criteria for MDD, obsessive-compulsive disorder, panic disorder, social phobia, or generalized anxiety disorder in their lifetime. Female gender, Caucasian ethnicity, recent or current physical problems (e.g., loss of bladder control, hypertension and back pain) and recent mental health facility visits were associated with antidepressant use in addition to mental disorders. Conclusions Many individuals who are prescribed and use antidepressant medications may not have met criteria for mental disorders. Our data indicate that antidepressants are commonly used in the absence of clear evidence-based indications. PMID:25188822

    Background A large portion of violence associated with drug use is due to drug dealing. These analyses sought to examine injection drug users' attitudes and experiences of drug dealer violence. Methods The current study used the 18-month follow up data of STEP into Action (STEP) study, an HIV prevention intervention among drug injectors and their risk network members conducted in Baltimore, Maryland. Four scales assessed acceptability of drug dealer violence, willingness to talk to drug users about avoiding drug dealer violence, social norms about reporting drug dealer violence, and intentions to report drug dealer violence to the police. Results Many (44%) of the 373 participants reported witnessing drug dealers' acts of violence within the prior 6 months. Although the majority of participants disagreed with statements on the acceptability of dealers using violence, only a minority indicated that they would call the police if they observed dealer violence. Most participants indicated that they would be interested in talking to drug users about how to avoid violent dealers. Males were more likely to report that violence was acceptable, whereas African Americans were less likely to condone violence. Those who were homeless and had higher incomes were more likely to report witnessing drug dealer violence. Conclusions These results suggest that it may be feasible to train current and former drug users and their risk network members in methods to promote violence reduction among drug dealers.

    The Kane and Lombard site is an 8.4-acre parcel of undeveloped land in Baltimore, Maryland. Dumping and burning of construction debris, domestic trash, and drums occurred at the site from 1962 until 1967 when the city passed an ordinance prohibiting the open burning of refuse. Illegal dumping continued from 1967 until approximately 1984, during which time many citations were issued for illegal burning on the property. In 1980, Maryland State inspectors observed between 400 and 500 drums, the majority of which were rusted, damaged and contained holes. Following an onsite property assessment, EPA authorized the immediate removal of 1,163 drums in 1984. Of those, 822 drums were classified as empty and 341 drums contained contaminants which included: benzene, toluene, xylene, PAHs, PCBs, and heavy metals. Approximately six inches of soil below the drums were removed and disposed offsite. The site was stabilized by regrading, capping and revegetation. Currently, soil and ground water are contaminated with these prior drum contaminants.

    This study used two modelling approaches to predict future urban landscapes for the Baltimore-Washington metropolitan area. In the first approach, we implemented traditional SLEUTH urban simulation model by using publicly available and locally-developed land cover and transportation data. Historical land cover data from 1992, 2001, 2006, and 2011 were used to calibrate the SLEUTH model and predict urban growth from 2011 to 2070. The SLEUTH model achieved 94.8% overall accuracy for validation year 2014. For the second modelling approach, we used a future population projection for 2050, aided by a strong population-imperviousness statistical relationship (R2 ~ 0.95), to predict impervious surface density for each county. These population-predicted impervious surface density values were compared to SLEUTH model output, at the county spatial scale. R2 of 0.84 suggested general agreement of overall pattern, although SLEUTH generated higher impervious surface density values for 36 out of 40 counties. For population-predicted impervious surface density, we further developed a lookup table approach to integrate SLEUTH output and generated a spatially explicit urban map for 2050. This lookup table approach has high potential to integrate population-predicted and SLEUTH-predicted urban landscape, especially when future population can be predicted with reasonable accuracy.

    Over the past several years, the combined utilization of hydraulic fracturing and horizontal drilling has led to a rapid increase in natural gas production, especially from the Marcellus Shale. To explore the impact of this activity downwind on regions with no natural gas production, the Hybrid Single Particle Lagrangian Integrated Trajectory (HYSPLIT) Model was used to generate 48-hour back-trajectories for summer, daytime hours from the years 2007-2014 in the Baltimore, MD and Washington, D.C. areas where hourly ethane measurements are available from Photochemical Assessment Monitoring Stations (PAMS). For each of the years investigated, unconventional well counts were obtained for counties in the surrounding states of Pennsylvania, Ohio, West Virginia, and Virginia, and counties exceeding a threshold of 0.05 wells/km2 were designated as counties with a high density of wells. The back-trajectories for each year were separated into two groups: those which passed through counties containing a high density of wells, and those which did not. Back-trajectories passing through high-density counties were further screened by applying a height criterion where trajectories beyond 10% above the mixing layer were excluded. Preliminary results indicate that air parcels with back-trajectories passing within the boundary layer of counties with a high density of unconventional natural gas wells correspond to significantly greater concentrations of observed ethane at these downwind monitors.

  5. Gait energetic efficiency in older adults with and without knee pain: results from the Baltimore Longitudinal Study of Aging.

    With aging, customary gait patterns change and energetic efficiency declines, but the relationship between these alterations is not well understood. If gait characteristics that develop with aging explain part of the decline in energetic efficiency that occur in most aging individuals, then efforts to modify these characteristics could delay or prevent mobility limitation. This study characterizes gait patterns in older persons with and without knee pain and tests the hypothesis that changes in gait characteristics due to knee pain are associated with increased energetic cost of walking in older adults. Study participants were 364 men and 170 women aged 60 to 96 years enrolled in the Baltimore Longitudinal Study of Aging (BLSA), of whom 86 had prevalent knee pain. Gait patterns were assessed at participant self-selected usual pace in the gait laboratory, and the energetic cost of walking was assessed by indirect calorimetry during self-selected usual pace walking over 2.5 min in a tiled corridor using a portable equipment. Participants with knee pain were less energetically efficient than those without pain (oxygen consumption 0.97 vs. 0.88 ml/(10 m · 100 kg); p = 0.002) and had slower gait speed and smaller range of motion (ROM) at the hip and knee joints (p < 0.05, for all). Slower gait speed and lower knee ROM in participants with knee pain and longer double support time and higher ankle ROM in participants without knee pain were associated with lower energetic efficiency (p < 0.05, for all). Slower gait speed and lower knee ROM were correlates of knee pain and were found to mediate the association between age and oxygen consumption. Although knee pain is associated with a higher energetic cost of walking, gait characteristics associated with energetic efficiency differ by pain status which suggests that compensatory strategies both in the presence and absence of pain may impact gait efficiency.

    Objective To investigate associations between serial measures of glucose intolerance and insulin resistance with in vivo amyloid burden, measured with 11C-PiB, and Alzheimer’s disease (AD) pathology at autopsy in a prospective cohort from the Baltimore Longitudinal Study of Aging. Methods Brain CERAD and Braak scores were correlated with measures of hyperglycemia, hyperinsulinemia, glucose intolerance and insulin resistance in 197 participants who had come to autopsy and had two or more oral glucose tolerance tests (OGTT) during life. Glucose intolerance was measured by fasting and 120-minute post-load glucose values. Insulin resistance was measured by fasting and 120-minute post-load serum insulin values and the ratio of serum glucose to insulin at baseline and following a glucose load. In addition, the same measures of glucose intolerance and insulin resistance were correlated with brain 11C-PiB retention in 53 living subjects. Results There were no significant correlations between measures of brain AD pathology or 11C-PiB derived amyloid load and either glucose intolerance or insulin resistance in subjects who had a mean of 6.4 ± 3.2 (S.D.) OGTT evaluations over 22.1 ± 8.0 (S.D.) years of follow-up. Thirty subjects with frank diabetes on medication also had AD pathology scores that were similar to the cohort as a whole. Conclusions In this prospective cohort with multiple assessments of glucose intolerance and insulin resistance, measures of glucose and insulin homeostasis were not associated with AD pathology.

    Since the release of the first Surgeon General’s report, the proportion of adult smokers in the U.S. has been reduced by half (U.S. Department of Health and Human Services, 2004). This success has not, however, been equally felt across all social strata. Recent survey data from Baltimore show considerably elevated smoking rates within urban, African-American communities. Of particular concern was that in some communities, over half of the young adults (18–24 years old) smoke cigarettes. As yet, there has been little focus on understanding or preventing cigarette smoking among young adults, particularly for those seeking entry into the workforce rather than being engaged in higher education. In this paper, we explore community factors contributing to high young adult smoking prevalence. Our analysis is based on data from four focus groups conducted in 2004 as part of a community-based participatory research project with two urban education and job training organizations. The focus group data reflect the experiences and opinions of 28 young adult program participants (23 smokers and 5 nonsmokers). The data highlight a normalized practice of buying and selling single cigarettes (“loosies”) within the community, with participants describing buying loose cigarettes as a preferred acquisition practice. We apply theories of informal economy and suggest that this alternative purchasing option may influence the smoking behavior of these young adults. We argue that public health efforts need to more closely consider the impact of community structures on program implementation. Overlooking key community characteristics such as the availability of single cigarettes may serve to intensify health disparities. PMID:17431795

    Background Apathy, a complex neuropsychiatric syndrome, commonly affects patients with Alzheimer’s disease. Prevalence estimates for apathy range widely and are based on cross-sectional data and / or clinic samples. This study examines the relationships between apathy and cognitive and functional declines in non-depressed community-based older adults. Methods Data on 1,136 community-dwelling adults age 50 and older from the Baltimore Epidemiologic Catchment Area (ECA) study, with 1 and 13 years of follow-up, were used. Apathy was assessed with a subscale of items from the General Health Questionnaire. Chi-square, t-tests, logistic regression, and Generalized Estimating Equations were used to accomplish the study’s objectives. Results The prevalence of apathy at Wave 1 was 23.7%. Compared to those without, individuals with apathy were on average older, more likely to be female, and have lower MMSE scores and impairments in basic and instrumental functioning at baseline. Apathy was significantly associated with cognitive decline (OR = 1.65, 95% CI = 1.06, 2.60) and declines in instrumental (OR = 4.42; 95% CI = 2.65, 7.38) and basic (OR=2.74; 95%CI= 1.35, 5.57) function at 1 year follow-up, even after adjustment for baseline age, level of education, race, and depression at follow-up. At 13 years of follow-up, apathetic individuals were not at greater risk for cognitive decline but were 2-fold more likely to have functional decline. Incidence of apathy at 1- year follow up and 13- year follow-up was respectively, 22.6% and 29.4%. Conclusions These results underline the public health importance of apathy and the need for further population-based studies in this area. PMID:20478091

    Obesity in older adults is a growing public health problem. Excess weight causes biomechanical burden to lower extremity joints and contribute to joint pathology. The aim of this study was to identify specific characteristics of gait associated with body mass index (BMI). Preferred and maximum speed walking and related gait characteristics were examined in 164 (50-84 years) participants from Baltimore Longitudinal Study of Aging (BLSA) able to walk unassisted. Participants were divided into three groups based on their BMI: normal weight (19< or =BMI<25 kg/m(2)), overweight (25< or =BMI<30 kg/m(2)) and obese (BMI 30< or =BMI<40 kg/m(2)). Total ankle generative mechanical work expenditure (MWE) in the anterior-posterior (AP) plane was progressively and significantly lower with increase in BMI for both preferred (p=0.026) and maximum speed walking (p<0.001). In the medial-lateral (ML) plane, total knee generative MWE was higher in obese participants in the preferred speed task (p=0.002), and total hip absorptive MWE was higher in obese in both preferred speed (p<0.001) and maximum speed (p=0.002) walking task compared to the normal weight participants. Older adults with obesity show spatiotemporal gait patterns that may help in reducing contact impacts. In addition, in obese persons mechanical energy usages tend to be lower in the AP plane and higher in the ML plane. Since forward progression forces are mainly implicated in normal walking, this pattern found in obese participants is suggestive of lower energetic efficiency.

  14. Implementing the chemical weapons convention

    1999-12-07

    In 1993, as the CWC ratification process was beginning, concerns arose that the complexity of integrating the CWC with national law could cause each nation to implement the Convention without regard to what other nations were doing, thereby causing inconsistencies among States as to how the CWC would be carried out. As a result, the author's colleagues and the author prepared the Manual for National Implementation of the Chemical Weapons Convention and presented it to each national delegation at the December 1993 meeting of the Preparatory Commission in The Hague. During its preparation, the Committee of CWC Legal Experts, a group of distinguished international jurists, law professors, legally-trained diplomats, government officials, and Parliamentarians from every region of the world, including Central Europe, reviewed the Manual. In February 1998, they finished the second edition of the Manual in order to update it in light of developments since the CWC entered into force on 29 April 1997. The Manual tries to increase understanding of the Convention by identifying its obligations and suggesting methods of meeting them. Education about CWC obligations and available alternatives to comply with these requirements can facilitate national response that are consistent among States Parties. Thus, the Manual offers options that can strengthen international realization of the Convention's goals if States Parties act compatibly in implementing them. Equally important, it is intended to build confidence that the legal issues raised by the Convention are finite and addressable. They are now nearing competition of an internet version of this document so that interested persons can access it electronically and can view the full text of all of the national implementing legislation it cites. The internet address, or URL, for the internet version of the Manual is http: //www.cwc.ard.gov. This paper draws from the Manual. It comparatively addresses approximately thirty

    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

    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.

    An important component of urban aerosol, diesel soot is a known respiratory irritant and contains mutagenic and carcinogenic organic compounds. To estimate student exposures to soot emitted from public diesel buses during commutes to city high schools, a portion of 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 an Environmental Justice Project. A total of 68.2 g of Ir as iridium(III)-2,4-pentanedionate were used to induce a concentration of 48.5 μg Ir ℓ -1 of fuel. Twenty samples were collected over 10 days while four students commuted on regularly scheduled buses and a fifth student commuted by private car. Individual samples integrated from 1 to 4 round trips. Iridium analyses were performed instrumentally after neutron activation with a detection limit (DL) of about 500 fg. For students commuting by bus and following protocols, Ir tracer concentrations ranged from 53±38 to >1980±49 fg m -3. Concentrations up to 3530±220 fg m -3 were observed for student #5, who sampled only when boarding and disembarking. Exposure were greatest for students commuting through the heavily trafficked central business district. Corresponding estimates of exposures to soot emitted from municipal buses ranged from ⩽3 to 82 ng soot m -3 (⩽145 ng m -3 for student #5), i.e. well below the exposure level of 2-10 μg m -3 total C from all sources, including the more than 30,000 diesel trucks which pass through the city's major toll facilities each day. Ir was undetectable in samples collected by the student commuting by car when its windows were closed, but comparable to those of the other students when commutes were made with windows open. The Ir tracer DL corresponds to about 21 ng soot, about half of which is carbon. This is far below the 230 ng reported for analysis by a highly sensitive thermal-optical technique.

  20. Conventionalism and integrable Weyl geometry

    NASA Astrophysics Data System (ADS)

    Pucheu, M. L.

    Since the appearance of Einstein's general relativity, gravitation has been associated to the space-time curvature. This theory introduced a geometrodynamic language which became a convenient tool to predict matter behaviour. However, the properties of space-time itself cannot be measurable by experiments. Taking Poincaré idea that the geometry of space-time is merely a convention, we show that the general theory of relativity can be completely reformulated in a more general setting, a generalization of Riemannian geometry, namely, the Weyl integrable geometry. The choice of this new mathematical language implies, among other things, that the path of particles and light rays should now correspond to Weylian geodesies. Such modification in the dynamic of bodies brings a new perception of physical phenomena that we will explore.

    Sexual violence and gender-based violence represent a major public health problem causing significant negative mental, physical, and social outcomes for victims. The rapidly growing population of Hispanic women in Baltimore are both more vulnerable to sexual assault and less able to access postassault services. In an effort to assess service utilization and community awareness of the Mercy Medical Center Sexual Assault Forensic Examiners/Forensic Nurse Examiners Program, we conducted a retrospective chart review of 2,322 women who were seen by the program between 2010 and 2013 and found that only 2.5% of the women were identified as Hispanic, about half of what Baltimore City demographic data would predict. This exploratory pilot project, augmented by key informant interviews, reveals that Hispanic women are underutilizing sexual assault services. Multiple barriers exist for Hispanic women in obtaining victim services, including lack of awareness within the community that the services exist, cultural factors, language barriers, lack of awareness of legal rights, and a fear of deportation.

    The Annual Energy Review 2003 is a statistical history of energy activities in the United States in modern times. Data are presented for all major forms of energy by production (extraction of energy from the earth, water, and other parts of the environment), consumption by end-user sector, trade with other nations, storage changes, and pricing. Much of the data provided covers the fossil fuels—coal, petroleum, and natural gas. Fossil fuels are nature’s batteries; they have stored the sun’s energy over millennia past. It is primarily that captured energy that we are drawing on today to fuel the activities of the modern economy. Data in this report measure the extraordinary expansion of our use of fossil fuels from 29 quadrillion British thermal units (Btu) in 1949 to 84 quadrillion Btu in 2003. In recent years, fossil fuels accounted for 86 percent of all energy consumed in the United States. This report also records the development of an entirely new energy industry—the nuclear electric power industry. The industry got its start in this country in 1957 when the Shippingport, Pennsylvania, nuclear electric power plant came on line. Since that time, the industry has grown to account for 20 percent of our electrical output and 8 percent of all energy used in the country. Renewable energy is a third major category of energy reported in this volume. Unlike fossil fuels, which are finite in supply, renewable energy is essentially inexhaustible because it can be replenished. Types of energy covered in the renewable category include conventional hydroelectric power, which is power derived from falling water; wood; waste; alcohol fuels; geothermal; solar; and wind. Together, these forms of energy accounted for about 6 percent of all U.S. energy consumption in recent years.

    Incidents of conventional weapons terror are increasingly part of the reality of the modern world, and in Israel, 19,948 incidents have been reported from September 2000 to December 2003. Most victims are injured in explosions resulting from suicide bombings. Exposure to the blast (primary mechanism of injury) may produce unique injuries affecting gas-containing organs, including perforation of the eardrums (most common injury); pulmonary blast injury, characterized by alveolar capillary disruption and bronchopleural fistulas; and bowel perforation, which is uncommon and may be delayed from 1 to 14 days after the injury. However, most injuries are the result of penetrating trauma (secondary mechanism) resulting from bomb fragments and nails, bolts, and steel pellets embedded in the bomb striking the victim, and blunt trauma (tertiary mechanism) sustained when the victim is propelled against an object by the blast wind. The severity of the injuries is increased when the blast occurs in a confined space. Victims of terror-inflicted injuries have a high Injury Severity Score (30% >16), a high requirement for intensive care unit admission (22.8% in Israel), and have a more prolonged hospital course and higher mortality than victims of any other form of trauma.

    Numerous submarine canyons along the United States middle Atlantic continental margin support enhanced productivity, diverse and unique habitats, active fisheries, and are vulnerable to various anthropogenic disturbances. During two cruises (15 Aug–2 Oct 2012 and 30 Apr–27 May 2013), Baltimore and Norfolk canyons and nearby areas (including two cold seeps) were intensively surveyed to determine demersal fish distributions and habitat associations. Overall, 34 ROV dives (234–1612 m) resulted in 295 h of bottom video observations and numerous collections. These data were supplemented by 40, 30-min bottom trawl samples. Fish observations were assigned to five general habitat designations: 1) sand-mud (flat), 2) sloping sand-mud with burrows, 3) low profile gravel, rock, boulder, 4) high profile, canyon walls, rocks or ridges, and 5) seep-mixed hard and soft substrata, the later subdivided into seven habitats based on amounts of dead mussel and rock cover. The influence of corals, sponges and live mussels (seeps only) on fish distributions was also investigated. Both canyon areas supported abundant and diverse fish communities and exhibited a wide range of habitats, including extensive areas of deep-sea corals and sponges and two nearby methane seeps (380–430 m, 1455–1610 m). All methods combined yielded a total of 123 species of fishes, 12 of which are either new records for this region or have new range data. Depth was a major factor that separated the fish faunas into two zones with a boundary around 1400 m. Fishes defining the deeper zone included Lycodes sp.,Dicrolene introniger, Gaidropsaurus ensis, Hydrolagus affinis, Antimora rostrata, andAldrovandia sp. Fishes in the deep zone did not exhibit strong habitat affinities, despite the presence of a quite rugged, extensive methane seep. We propose that habitat specificity decreases with increasing depth.

    Objective To determine the age- and ethnicity-specific prevalence of decreased visual acuity (VA) in White and African-American preschool aged children. Design Cross-sectional study. Participants The Baltimore Pediatric Eye Disease Study is a population-based evaluation of the prevalence of ocular disorders in children aged 6 through 71 months in Baltimore, Maryland, United States. Among 4,132 children identified, 3,990 eligible children (97%) were enrolled and 2,546 children (62%) were examined. This report focuses on 1,714 of 2,546 examined children (67%) who were aged 30 through 71 months. Methods Field staff identified 63,737 occupied dwelling units in 54 census tracts. Parents or guardians of eligible participants underwent an in-home interview and eligible children underwent a comprehensive eye examination including optotype VA in children aged 30 months and older with protocol-specified retesting of children with VA worse than an age-appropriate standard. Main Outcome Measures The proportion of children aged 30 through 71 months testable for VA and the proportion with decreased VA as defined by preset criteria. Results VA was testable in 1,504 of 1,714 children (87.7%) 30 through 71 months of age. It was decreased at the initial test (wearing glasses if brought to the clinic) in both eyes of 7 of 577 White children (1.21%, 95% Confidence Interval [CI] = 0.49, 2.50) and 13 of 725 African-American children (1.79%, 95% CI = 0.95, 3.08), a difference that is not statistically significant. Decreased VA in both eyes after retesting was found in 3 of 598 White children (0.50%, 95% CI = 0.10, 1.48) and 8 of 757 African-American children (1.06%, 95% CI = 0.45, 2.10), also not statistically significantly different. Uncorrected ametropia explained the decreased VA on initial testing in ten of the twenty children. Conclusions Decreased VA in both eyes of children 30 through 71 months of age at presentation in urban Baltimore was 1.2% among White children and 1.8% among

    A large literature suggests that social norms contribute to HIV and substance use related behaviors. Less attention has been given to neighborhood factors that may contribute to the development of norms about risky behaviors. We examined the cross-sectional associations between perceptions of one’s neighborhood and norms of perceived prevalence of, and peer support for sex exchange and risky injection behaviors. The sample consisted of 719 people who reported injecting heroin and cocaine and did not move in the past 6 months in Baltimore, MD. Living in a neighborhood with disorder was associated with believing that others exchanged sex, practiced risky injection behaviors (descriptive norms) and approved of risky injection behavior (injunctive norms).

    This paper examines the activities of churches in Baltimore, Maryland, concerning the issues of sexuality, whether they potentially stigmatize persons with or at risk for HIV/AIDS, and to what extent individual agency versus institutional forces influence churches in this regard. In-depth interviews were conducted with 20 leaders from 16 churches and analyzed using a grounded theory methodology. Although many churches were involved in HIV/AIDS-related activities, the content of such initiatives was sometimes limited due to organizational constraints.

    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. PMID:24437544

    Commonly used methods for assay of haemoglobin A(1c) (HbA(1c)) are susceptible to interference from the presence of haemoglobin variants. In many systems, the common variants can be identified but scientists and pathologists must remain vigilant for more subtle variants that may result in spuriously high or low HbA(1c) values. It is clearly important to recognize these events whether HbA(1c) is being used as a monitoring tool or, as is increasingly the case, for diagnostic purposes. We report a patient with a rare haemoglobin variant (Hb Sinai-Baltimore) that resulted in spuriously low values of HbA(1c) when assayed using ion exchange chromatography, and the steps taken to elucidate the nature of the variant.

    This study assessed the role of some common mental health conditions as mediators in the pathway between suffering life events and using mental health services. The participants were from the Baltimore Epidemiologic Catchment Area cohort, interviewed in 1993 to 1996 and 2004 to 2005. Longitudinal data analysis was used to identify models with significant mediation. Only alcohol abuse/dependence disorder was a significant mediator in the pathway between suffering a life-threatening illness and using mental health services in a general medical setup. Female gender, being more than 65 years old, prior use of services and availability of health insurance were some of the factors that significantly predicted service use in that model. Some of other factors like social networks and social support, attitudes towards services, and stigma, may play a role in determining service use. Future research should investigate the role of such factors as mediators for mental health service use. PMID:20215995

    We present evidence that the principal sources for Early Cretaceous (Berriasian-Valanginian) gravity-flow deposits of the northern Hatteras Basin were three large shelf-edge deltas located along the outer margin of the Baltimore Canyon Trough, ∼ 100 km southeast of Cape Charles, Virginia, Ocean City, Maryland, and Long Branch, New Jersey. Sedimentary detritus from the central Appalachian highlands and the Maryland-Virginia coastal plain was transported across the Early Cretaceous continental shelf to form the Cape Charles and Ocean City deltas, whereas deposits of the Long Branch delta came chiefly from the Adirondack and New England highlands. Each delta supplied sediment gravity flows to large slope aprons and submarine-fan complexes on the Early Cretaceous continental slope and rise. The most conspicuous distributary of sediment on the Early Cretaceous continental rise extends 500 km basinward from the Ocean City delta, where its distal deposits were cored at Deep Sea Drilling Project Site 603.

    Setting: The Health Sciences and Human Services Library (HS/HSL), University of Maryland, Baltimore (UMB), is located in an urban environment on the west side of downtown Baltimore. Founded in 1813, the library opened its current building in 1998 and is one of the largest health sciences libraries in the United States, with 6 floors and over 180,000 gross square and 118,000 net assignable square feet (NASF). Project: The initial discussions in late 2005 involved moving campus offices into the library. Almost immediately, it was recognized that a much larger renovation was needed due to the scope of the work. The vice president for academic affairs, the library executive director, and campus planners agreed that if the renovation was done thoughtfully, multiple needs could be met, including new office spaces, better user spaces, and synergy with the new campus center being built next door. Planning: The planning, design, and construction process was multifaceted and on a fast track. Although the final piece of the renovation was completed in June 2009, the majority of the planning, design, and construction took place between March 2006 and June 2008. All tenants were involved with office design. Library staff were involved in designing the public spaces and planning the strategy for weeding and shifting. Outcomes: Approximately 8,000 NASF was reallocated to new office space from shelving space, amounting to approximately 6.7% of the building NASF and approximately 10.6% of the public space in the building. The majority of new offices in the building report to the same vice president and are student focused and service oriented, with similar missions to that of the library resulting in a very harmonious cohabitation. Additional units with these missions and reporting structure are located in the new campus center, creating a synergy between the two buildings. PMID:20098653

    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.

    Al-Amoudi, Ismael; Latsis, John

    2014-06-01

    This paper investigates a puzzling feature of social conventions: the fact that they are both arbitrary and normative. We examine how this tension is addressed in sociological accounts of conventional phenomena. Traditional approaches tend to generate either synchronic accounts that fail to consider the arbitrariness of conventions, or diachronic accounts that miss central aspects of their normativity. As a remedy, we propose a processual conception that considers conventions as both the outcome and material cause of much human activity. This conceptualization, which borrows from the économie des conventions as well as critical realism, provides a novel perspective on how conventions are nested and defined, and on how they are established, maintained and challenged.

    2015-09-01

    The clinical and radiographic outcomes of 88 patients who underwent primary total hip arthroplasty with either conventional polyethylene or cross-linked polyethylene (XLPE) from the same manufacturer were compared. There were no significant differences between the 2 subpopulations regarding average age, gender, side affected, or prosthetic stem and cup size. The average follow-up was 104 months (range, 55 to 131 months). To the authors' knowledge, this is the longest follow-up for this particular insert. Clinical and radiographic evaluations were performed at 1, 3, 6, and 12 months and then annually. Results showed that XLPE has a significantly greater wear reduction than that of standard polyethylene in primary total hip arthroplasty. At the longest available follow-up for these specific inserts, XLPE proved to be effective in reducing wear. PMID:26375527

    A conventional bale feedstock design has been established that represents supply system technologies, costs, and logistics that are achievable today for supplying herbaceous feedstocks as a blendstock with coal for energy production. Efforts are made to identify bottlenecks and optimize the efficiency and capacities of this supply system, within the constraints of existing local feedstock supplies, equipment, and permitting requirements. The feedstock supply system logistics operations encompass all of the activities necessary to move herbaceous biomass feedstock from the production location to the conversion reactor ready for blending and insertion. This supply system includes operations that are currently available such that costs and logistics are reasonable and reliable. The system modeled for this research project includes the uses of field-dried corn stover or switchgrass as a feedstock to annually supply an 800,000 DM ton conversion facility.

  2. Annual Cycle Energy System characteristics and performance

    SciTech Connect

    Abbatiello, L.A.

    1980-01-01

    The Annual Cycle Energy System (ACES) provides space heating, air conditioning, and domestic water heating while using substantially less energy than competing systems providing the same services. The ACES is based on an electrically driven, unidirectional heat pump that extracts heat from an insulated tank of water during the heating season. As the heat is extracted, most of the water freezes, and the stored ice provides air conditioning in the summer. A single-family residence near Knoxville, Tennessee is being used to demonstrate the energy conserving features of the ACES. A second similar house, the control house, has been used to compare the performance of the ACES to both an electric resistance heating and hot water with central air conditioning system and an air-to-air heat pump system. The results of the first year's operation from November 1977 through mid-September 1978 showed that the ACES consumed 9012 kWh of electricity while delivering an annual coefficient of performance (COP) of 2.78. The control house consumed 20,523 kWh of electricity while delivering an annual COP of 1.13. The second annual cycle was started on December 1978. The ACES was compared with an air-to-air heat pump during this period. During the ice storage portion of this test year, December 1, 1978 to September 1, 1979, 5705 kWh of electricity was used by the ACES, compared to 12,014 kWh for the control house. The respective COPs are 1.40 for the control house with the heat pump and 2.99 for the ACES house during this period. Annual energy consumption for the test year was 6597 kWh and the annual COPs were 1.41 for the control house and 2.81 for ACES. ACES is achieving its anticipated performance. The ACES concept and its general engineering performance as compared to conventional HVAC system are described and discussed.

  6. Nematode Communities in Organically and Conventionally Managed Agricultural Soils

    PubMed Central

    Neher, Deborah A.

    1999-01-01

    Interpretation of nematode community indices requires a reference to a relatively undisturbed community. Maturity and trophic diversity index values were compared for five pairs of certified organically and conventionally managed soils in the Piedmont region of North Carolina. Available nitrogen (nitrate, ammonium) was estimated at various lag periods relative to times of sampling for nematode communities to determine the strength of correlative relationship between nematode communities and nitrogen availability. Soils were sampled six times yearly in 1993 and 1994 to determine the best time of year to sample. Maturity values for plant parasites were greater in organically than conventionally managed soils, and differences between management systems were greater in fall than spring months. However, other maturity and diversity indices did not differ between the two management practices. Differences in crop species grown in the two systems accounted for most differences observed in the community of plant-parasitic nematodes. Indices of free-living nematodes were correlated negatively with concentrations of ammonium, whereas indices of plant-parasitic nematodes were correlated positively with concentrations of nitrate. Due to the similarity of index values between the two systems, organically managed soils are not suitable reference sites for monitoring and assessing the biological aspects of soil quality for annually harvested crops.

    Microbes and their toxins are biological weapons that can cause disease in humans, animals or plants, and which can be used with hostile intent in warfare and terrorism. Biological agents can be used as weapons of mass destruction and therefore, immense human and social and major economical damage can be caused. Rapid development of life sciences and technologies during the recent decades has posed new challenges to the Biological Weapons Convention. The Convention states that the States Parties to the BWC strive to ensure that the Convention remains relevant and effective, despite changes in science, technology or politics.

    The knee is a common site for bone tumors, whether clinically painful or not. Conventional radiology has been established as the first line of investigation in patients with knee pain and can reveal lesions that often generate questions not only for the generalist physician but also for the radiologist or general orthopedist. History, image examination, and histopathological analysis compose the essential tripod of the diagnosis of bone tumors, and conventional radiology is an essential diagnostic tool in patients with knee pain. This pictorial essay proposes to depict the main conventional radiography findings of the most common bone tumors around the knee, including benign and malignant tumors, as well as pseudo-tumors.

  9. Laser Ablation Trace Element Analysis of Modern and Fossil Desmophyllum dianthus from Norfolk and Baltimore Canyons in Mid-Atlantic Ocean

    Deep-sea cup corals are a promising archive for paleoceanographic reconstructions as they are globally distributed with some fossil specimens living throughout the Holocene and into the Last Glacial period. Here we explore the utility of using laser ablation (LA)- ICP-MS to measure the trace elements and δ11B in solitary scleractinian, cup corals, Desmophyllum dianthus collected in Norfolk and Baltimore Canyons from the Mid-Atlantic Ocean. Twelve modern and twenty-six sub-fossil D. dianthus, were collected between a depth range of 400m - 1400m with ambient seawater pH range of 7.89 - 8.00. Modern seawater column chemistry including radiocarbon, nutrients, total alkalinity and particulate trace elements were measured to calibrate geochemical proxies in the live specimens. Radiocarbon measurements indicate sub-fossil specimens lived as long ago as 800 years. A suite of trace elements including P/Ca, Ba/Ca, and U/Ca were analyzed to reconstruct nutrient changes and carbonate ion concentrations. Using previously published calibration equations, modern coral P/Ca ratios yield dissolved inorganic P values of 0.24 - 1.70 μmol/L in line with measured values of 0.1-2.5 μmol/L in the water column. In addition, Ba/Ca (nutrients) yield dissolved Ba values of 25-137 ±16 nmol/kg and U/Ca results yield carbonate ion concentrations of 40-129 ±29 μmol/kg, which are both consistent with previously published work. This study represents the first ever LA-ICP-MS measurements of δ11B using modern and sub-fossil D. dianthus where the modern corals averaged δ11B=18.15±0.01‰. These results are similar to previously published solution ICP-MS results, but using published pH-δ11B calibration equation yields higher pH values than in-situ pH values suggesting future modern calibration work is necessary. Overall, these results show promise for using sub-fossil D. dianthus to reconstruct biogeochemical processes at intermediate and deep waters in Norfolk and Baltimore Canyons.

    Background Alcohol use is a risk factor for the acquisition of human immunodeficiency virus (HIV) among African American men who have sex with men (MSM). Mobile phone-based ecological momentary assessments (EMA) could minimize bias due to retrospective recall and thus provide a better understanding of the social and structural context of alcohol use and its relationship with HIV-related risk behaviors in this population as well as other highly stigmatized populations. Objective We describe the study design and the implementation, feasibility, reactivity, and acceptability of an EMA study of alcohol use and HIV-related behaviors among African American MSM in Baltimore. Methods Participants were recruited through flyers and word-of-mouth in Baltimore from September 2013 to November 2014. Each participant was loaned an Android smartphone and instructed to respond to multiple prompts from the mobile app for 4 weeks. Data were collected through (1) random prompts delivered three times daily assessing participants’ location, activity, mood, and social context, (2) daily prompts capturing drinking and sex events occurring in the past 24 hours, and (3) event-contingent responses collecting participants’ self-reported episodes of drinking. Results A total of 16 participants enrolled in the study. The current analyses focused on 15 participants who completed at least 24 days of follow-up (mean follow-up time 29 days; range 24-35 days). Study participants (N=15) were a median 38 years of age (range 27-62 years) with low levels of income and educational attainment. Ten individuals self-reported living with HIV/AIDS, over half reported drinking alcohol at least 2-3 times a week, and a third reported binge drinking (ie, 6 or more drinks on one occasion) on a weekly basis. Based on the Alcohol Use Disorders Identification Test (AUDIT) score, nearly half were classified as hazardous drinkers (score 8-15) and a fifth were likely dependent (score ≥16). A total of 140

  11. The association between nutrition transition score and measures of obesity: results from a cross-sectional study among Latina/o immigrants in Baltimore

    Background Studies suggest that US Latinos have a higher prevalence of obesity than White Americans. However, obesity may differ by pre-immigration factors and Latinos’ cultural representations of ideal body image. This paper explores whether country of origin’s stage in the nutrition transition is related to Latino immigrants’ BMI category and self-perception of weight. Methods Primary data originated from a cross-sectional questionnaire of Latina/o immigrants in Baltimore in 2011. A convenience sample of self-identified Latinos, ≥18 years old, living in Baltimore was recruited from a community-based organization. Data for each country represented in the sample were obtained from the WHO Demographic and Health Surveys and the UN Food and Agriculture Organization. Each country was scored for its stage in the nutrition transition using a six-point scoring system. Descriptive statistics were conducted to characterize the sample. Bivariate analyses were conducted to examine the relationship between the outcome variables and the predictors. Multivariate logistic regressions were conducted to examine whether a country’s stage in the nutrition transition increased one’s odds of having an obese BMI score (≥30 kg/cm2) and perceiving one’s weight as overweight, while controlling for socio-demographic variables. Results The sample (n = 149) consisted of immigrants from 12 Latin American countries. Participants lived in the US for x=10.24 years. About 40% of the sample had BMI ≥30 kg/m2 (obese). The longer Latina immigrants’ lived in the US, the less likely their country of origin’s nutrition transition score would increase their odds of having a BMI ≥30 kg/m2 (OR = 0.97 p < 0.04). The higher the country of origin’s nutrition transition score, the more likely BMI influenced Latino immigrants’ perception of their weight as above normal (OR = 1.06, p < 0.04). The effect of the nutrition transition score had a stronger effect
