    This Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) image of Baltimore was acquired on April 4, 2000, and covers an area of 17 by 20 km. Combining green, red, and near-infrared light to create a false-color composite, the image shows vegetation as red, water as blue, and urban areas as grey. 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. In one week (January 28, 2001), the Baltimore Ravens will play the New York Giants in Super Bowl XXXV, the championship game of the National Football League (NFL).

    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.

    2002-01-01

    Because of concern for heat-related mortality in vulnerable populations, particularly the elderly, practical epidemiologic methods are needed for the assessment of ambient heat exposure on individuals. We used a personal monitor to measure body temperature, ambient temperature, heart rate, and activity level of 42 elderly residents of Baltimore, Maryland, in the summer months of 2000. Each participant was monitored for approximately 48 hr to examine the association between ambient temperature and body temperature, using regression methods that account for highly correlated data within individuals. We also examined the associations of Baltimore temperature data with personal ambient temperature and body temperature. An average 0.15 degrees F [95% confidence interval (CI), 0.05-0.25] increase in median body temperature was found for each 1 degrees F increase in median ambient temperature. Heart rate and activity level were not found to be related to body temperature or ambient temperature, although heart rate was associated with activity level. Median heart rate increased an average of 0.17 (95% CI, 0.13-0.21) beats per minute for every unit increase in median activity level. Personal ambient temperature was slightly lower than Baltimore temperatures, whereas an association was not found between body temperature and Baltimore temperatures. The protocol established in this study for heat exposure assessment could feasibly be applied on a larger scale. PMID:12460801

    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. We also share the early lessons learned in the center’s design. PMID:24028238

    1999-01-01

    The Gwynns Falls watershed has been selected as the primary study area for the Baltimore Ecosystem Study, as part of the National Science Foundation?s Long-Term Ecological Research program. Because the Baltimore Ecosystem Study will be investigating long-term hydrologic changes in the Gwynns Falls watershed, a compilation of existing data resources for the watershed is necessary. This report discusses hydrologic characteristics and presents a compilation of historical data resources for the Gwynns Falls watershed. Tables are presented that list active and discontinued continuous-record streamflow-gaging stations, nontidal crest-stage partial-record stations, low-flow partial-record stations, and water-quality partial-record stations operated by the U.S. Geological Survey, Maryland-Delaware-D. C. District, in the Gwynns Falls watershed. Statistics regarding the number of inventoried ground-water wellsin or bordering the Gwynns Falls watershed also are presented. A summary of additional data resources for the Gwynns Falls watershed is provided. This includes (1) an inventory of selected U.S. Geological Survey studies and reports that contain historical data or basin characteristics for streams in the watershed, (2) a listing of indirect flood-discharge measurements that have been made at several monitoring stations in the watershed, (3) a brief discussion of channel-stability and bridge-scour data collected by the U.S. Geological Survey in the watershed during 1990?95, (4) a listing of climatological data stations in the watershed and in the surrounding regional area, and (5) a listing of other selected reports that include data or information on the Gwynns Falls watershed.

    Ground level ozone, or tropospheric ozone, forms smog and becomes directly harmful to humans by exacerbating respiratory conditions, primarily asthma (Knowlton et al. 2004). As climate change progresses, increased ozone concentrations emerge as a major public health concern (Gardiner et al. 2011). Increasing ground level ozone concentrations have been directly correlated with rising temperatures (Patz et al. 2005). The projected increase in ozone concentration caused by climate induced temperature change is 1-2 ppb in 2020 and 2-7 ppb in 2050, with associated temperature increases of 1-2 degrees Fahrenheit and 2-5.5 degrees Fahrenheit, respectively (UCS, 2011). Those with existing respiratory conditions, children and the elderly, and those who spend a significant amount of time outdoors are the most sensitive to ground level ozone pollution (Schlink et al. 2006). In Maryland, there would be approximately 68,894 occurrences of acute respiratory symptoms associated with a 2 ppb climate penalty in 2020, and the total costs for health impacts associated with this would be approximately $133,398,027 (UCS, 2011). In their 2011 "State of the Air" report, the American Lung Association rated the Washington/Baltimore/Northern Virginia region as one of the 25 most ozone polluted regions nationwide (ALA, 2011). We examine asthma hospital admissions data for the Maryland/DC metropolitan region between 2005 and 2010 and identify possible correlations with the reported ozone measurements provided by the EPA (CASTNET). We examine trends between the archived temperatures from NCEP reanalysis data, the EPA ozone data, and reported asthma cases. We utilize these trends to investigate the future impact of changes in ozone concentration based on the IPCC AR4 and SRES emissions scenarios and attempt to quantify the financial burden of its implications. Visualizations from this data can serve as important educational and planning tools for decision makers in the Maryland, DC, and Virginia regions.

  4. Sediment contributions from floodplains and legacy sediments to Piedmont streams of Baltimore County, Maryland

    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 positively correlated with drainage area. Measured deposition within channels accounted for an average of 46% (28-75%) of gross erosion, with deposition increasingly important in larger drainages. Legacy sediments accounted for 6-90% of bank erosion at individual study segments, represented about 60% of bank height at most exposures, and accounted for 57% (± 16%) of the measured gross erosion. Extrapolated results indicated that first- and second-order streams accounted for 62% (± 38%) of total streambank erosion from 1005 km2 of northern Baltimore County. After accounting for estimated redeposition, extrapolated net streambank sediment yields (72 Mg/km2/y) constituted 70% of estimated average Piedmont watershed yields (104 Mg/km2/y). The results suggest that streambank sediments are a relatively large source of sediment from Piedmont tributaries to the Chesapeake Bay.

  5. Structural vulnerabilities to HIV/STI risk among female exotic dancers in Baltimore, Maryland.

    2015-01-01

    Female exotic dancers (FEDs) are an important, yet understudied group of women who may engage in drug- and sex-related HIV/STI risk behaviors through their work. The study objective was to identify co-occurring indicators of vulnerability (e.g., housing, income, incarceration) associated with HIV/STI risk behavior among FEDs in Baltimore, Maryland. Surveys administered during July 2008-February 2009 captured socio-demographic characteristics, drug use, and sexual practices among dancers (N = 101) aged ≥18 years. Multivariate logistic regression was used to assess the relationship between vulnerability and risk behavior. Dancers with a high vulnerability score (i.e., 2 or more indicators) were more likely to report sex exchange (AOR: 10.7, 95% CIs: 2.9, 39.9) and multiple sex partnerships (AOR: 6.4, 95% CIs: 2.3, 18.3), controlling for demographics and drug use, compared to their less vulnerable counterparts. Findings point to primacy of macro-level factors that need to be addressed in HIV/STI prevention efforts targeting this and other high-risk populations. PMID:25588144

    2012-01-01

    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.

    Objectives. We examined the association between the expansion of methadone and buprenorphine treatment and the prevalence of heroin overdose deaths in Baltimore, Maryland from 1995 to 2009. Methods. We conducted a longitudinal time series analysis of archival data using linear regression with the Newey–West method to correct SEs for heteroscedasticity and autocorrelation, adjusting for average heroin purity. Results. Overdose deaths attributed to heroin ranged from a high of 312 in 1999 to a low of 106 in 2008. While mean heroin purity rose sharply (1995–1999), the increasing number of patients treated with methadone was not associated with a change in the number of overdose deaths, but starting in 2000 expansion of opioid agonist treatment was associated with a decline in overdose deaths. Adjusting for heroin purity and the number of methadone patients, there was a statistically significant inverse relationship between heroin overdose deaths and patients treated with buprenorphine (P = .002). Conclusions. Increased access to opioid agonist treatment was associated with a reduction in heroin overdose deaths. Implementing policies that support evidence-based medication treatment of opiate dependence may decrease heroin overdose deaths. PMID:23488511

  8. Abundance and Characterization of Dissolved Organic Carbon in Suburban Streams of Baltimore, Maryland, USA

    Mora, G.; Fazekas, M.

    2014-12-01

    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.

    During July 2011, NASA's DISCOVER-AQ project conducted flights over the Baltimore metropolitan area. The intent of the project is articulated by its acronym, Deriving Information on Surface Conditions from COlumn and VERtically Resolved Observations Relevant to Air Quality. By collecting concurrent observations at the surface and from aircraft overhead using in situ instruments and remote sensors, the project seeks to characterize the challenge satellites face in separating conditions at the surface from the overlying atmosphere. Detailed information on the composition and vertical structure of the lower atmosphere was collected using NASA's P-3B aircraft, resulting in 254 soundings across 14 different days and 6 surface sites. Soundings were conducted in a spiral pattern generally extending from 1,000 feet above the ground to 10,000 feet, which was almost always high enough to reach the lower free troposphere. While the purpose of these soundings was to document vertical structure, the footprint of the spiral pattern (~5 km in diameter) raises the possibility of significant horizontal structure as well. We introduce a method for diagnosing these horizontal gradients and apply it to the DISCOVER-AQ observations. Specific examples as well as overall statistics on the presence and magnitude of horizontal gradients in the aircraft soundings will be presented. These horizontal gradients have their own significance in that the spiral footprint is comparable to fine resolution models as well as current and future satellite observations.

  10. The Influence of Land Surface Heterogeneities on Heavy Convective Rainfall in the Baltimore-Washington Metropolitan Area

    NASA Astrophysics Data System (ADS)

    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.

  11. Urban Effects on Storm Event Hydrologic Response in Metropolitan Baltimore, MD

    Smith, B. K.; Smith, J. A.; Baeck, M. L.; Villarini, G.

    2011-12-01

    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.

    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 the velocity exponents for all four stations on the Gwynns Falls are larger than the average value of 0.34. For stations 01589300 and 01589352, the exponents for mean velocity are about twice as large as the average value. Analyses of cross-sectional area, channel width, mean channel depth, and mean velocity in conjunction with changes in drainage area and annual mean discharge indicated that channel width is much more responsive to changes in drainage area and annual mean discharge than are mean channel depth or mean velocity. Cross-sectional area, which combines the effects of channel width and mean channel depth, was also found to be highly responsive to changes in drainage area and annual mean discharge.

    Planning and development of expanding metropolitan regions require consideration of earth science issues related to issues involving scale, space (location), geologic terrain and physiographic units, and information transfer. This paper explores these matters with examples from the Salt Lake City, Utah area and Mid-Atlantic region of Baltimore-Washington that include water supply and natural hazards (earthquakes, landslides, and sinkholes.) Information transfer methods using physiographic units at national, regional, local and site scales serve to communicate relevant geologic constraint and natural resource information.

    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.

    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.

    Men who have sex with men (MSM) in Baltimore are at disproportionately high risk for HIV and syphilis infection. 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. PMID:26078117

    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.

    Toxocara species ova were found in 16 of 146 (11 per cent) soil samples collected from backyards and gardens of private residences within Baltimore City. The recovery rate of parasite ova was similar for households regardless of their grouping by pet ownership characteristics or the presence of visible animal feces. The findings demonstrate the common occurrence of these eggs in locations likely to be important in the transmission of visceral larva migrans. PMID:4025663

  3. 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.

  4. Serologic evidence of rickettsialpox (Rickettsia akari) infection among intravenous drug users in inner-city Baltimore, Maryland.

    We tested single serum samples from 631 intravenous (i.v.) drug users from inner-city Baltimore, Maryland for serologic evidence of exposure to spotted fever group rickettsiae. A total of 102 (16%) individuals had titers > or = 64 to Rickettsia rickettsii by an indirect immunofluorescence assay. Confirmation that infection was caused by R. akari was obtained by cross-adsorption studies on a subset of serum samples that consistently resulted in higher titers to R. akari than to R. rickettsii. Current i.v. drug use, increased frequency of injection, and shooting gallery use were significant risk factors for presence of group-specific antibodies reactive with R. rickettsii. There was a significant inverse association with the presence of antibodies reactive to R. rickettsii and antibodies reactive to the human immunodeficiency virus. This study suggests that i.v. drug users are at an increased risk for R. akari infections. Clinicians should be aware of rickettsialpox, as well as other zoonotic diseases of the urban environment, when treating i.v. drug users for any acute febrile illness of undetermined etiology.

    In Chesapeake Bay, Maryland, USA, some of the most contaminated sediments are found in the highly industrialized Baltimore Harbor-Patapsco River area. As part of a comprehensive assessment of sediment quality in this system, sediment toxicity was assessed in 10-d acute tests with the estuarine amphipod Leptocheirus plumulosus. Mean amphipod survival was significantly reduced in 7 of the 25 samples tested despite the occurrence of minor experimental artifacts. The most toxic sediments were collected from Bear Creek; other areas exhibiting toxicity included the Inner Harbor and Colgate Creek. Marginal toxicity was observed in samples from Curtis Creek, Lazeretto Point, and Back River. Negative relationships were detected between survival and concentrations of select sediment-associated contaminants, whereas a very strong positive association existed between survival in laboratory exposures and density of L. plumulosus at the test sites. A weight of evidence approach, including correlation analyses, a model of polycyclic aromatic hydrocarbon bioavailability, and comparisons to benchmark sediment levels, was used to tentatively identify classes of contaminants that contributed to the observed toxicity. Analysis of results suggested that toxicity at stations in Bear Creek and Colgate Creek may have been driven by sediment-associated metals, whereas toxicity at stations in the Inner Harbor was likely due to both metal and organic contaminants. The observed relationships among toxicity test results, concentrations of sediment-associated contaminants, and abundance of L. plumulosus at the test sites suggests that acute toxicity tests with this species are indicative of adverse biological effects in the field.

  6. Gender differences in street economy and social network correlates of arrest among heroin injectors in Baltimore, Maryland.

    In a sample of 761 heroin injectors in Baltimore, Maryland, correlates of arrest for drug-related and non-drug-related criminal offenses, by gender, were examined. This investigation examined gender differences in involvement in the drug economy and correlates of arrest. Correlates included roles in the street drug economy, social network attributes, and economic and demographic variables. Gender differences were found. Selling drugs was strongly associated with drug-related arrests for males. Steering (i.e., publicizing drug brands) was highly associated with drug-related arrests for females. Level of heroin addiction was associated with drug-related arrests for males, but not for females. The associations of social network variables with arrests also differed by gender. For females but not males, a higher number of females in one's network was associated with a lower frequency of arrests. For males, having at least one heroin injector in the personal network was associated with a decreased frequency of arrest, while for females the direction of the association was reversed. These findings suggest the importance of modeling drug behaviors by gender. PMID:12930885

    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

  9. 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.

  10. Occurrence and distribution of microbiological contamination and enteric viruses in shallow ground water in Baltimore and Harford counties, Maryland

    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, somatic coliphage, or bacteriophages of Bacteroides fragilis. About 3 percent of the sam-ples (3 of 87) had oxidized nitrogen concentra-tions that exceeded the U.S. Environmental Protection Agency?s Maximum Contaminant Level of 10.0 milligrams per liter. A statistical analysis showed that no significant relation exists between the presence of bacteria or coliphage and all variables, except the mean temperature of the water sample as measured in the field. Additionally, the concentration of total coliform bacteria had a statistically significant, moderately strong cor-relation with the concentration of sulfate and sample pH as measured at the U.S. Geological Survey National Water-Quality Laboratory in Denver, Colorado.

  11. Hydrogeology, digital solute-transport simulation, and geochemistry of the Lower Cretaceous aquifer system near Baltimore, Maryland

    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 aquifer has a smaller zone of brackish-water contamination that has decreased in size since 1945. Borehole data demonstrate that the Arundel Formation has been breached by Pleistocene river channels near the Harbor district. These erosional channels provide a conduit for brackish water to intrude into the Patuxent aquifer. A two-dimensional areal solute-transport model of the Patuxent aquifer was constructed. This model was designed to estimate the future movement of the brackish-water plume based on alternative scenarios of aquifer use. Model simulations suggest that the plume will remain relatively immobile if 1982 pumping patterns continue into the foreseeable future. However, increased pumpage in the Marley Neck peninsula could draw the plume to the southeast and increase contamination of the Fairfield area. The water quality of the Patuxent aquifer is extremely variable. Because of this variability, it is useful to divide the aquifer into three water-quality zones: Zone 1 -- This zone corresponds to the plume of brackish-water contamination. Zone 2 -- This zone exhibits evidence of urbanization-related contamination such as measurable concentrations of organic chemicals and elevated concentrations of trace elements and total organic carbon. Zone 3 -- Water composition in this zone is controlled exclusively by naturally occurring chemical processes. These processes are dominated by reactions involving dissolved iron. Near the outcrop area, oxidation of pyrite and lignite consumes dissolved oxygen and produces ledges of iron hydroxide-cemented sandstones and conglomerates. The predominant dissolved iron species in oxic water is Fe(OH)2+. Downgradient, the water becomes anoxic and sulfate reduction becomes an important process. The predominant dissolved iron species in anoxic water is Fe2+.

    Data collected from 2002 through 2004 were used to assess geomorphic characteristics and geomorphic changes over time in a selected reach of Minebank Run, a small urban watershed near Towson, Maryland, prior to its physical restoration in 2004 and 2005. Longitudinal profiles of the channel bed, water surface, and bank features were developed from field surveys. Changes in cross-section geometry between field surveys were documented. Grain-size distributions for the channel bed and banks were developed from pebble counts and laboratory analyses. Net changes in the elevation of the channel bed over time were documented at selected locations. Rosgen Stream Classification was used to classify the stream channel according to morphological measurements of slope, entrenchment ratio, width-to-depth ratio, sinuosity, and median-particle diameter of the channel materials. An analysis of boundary shear stress in the vicinity of the streamflow-gaging station was conducted by use of hydraulic variables computed from cross-section surveys and slope measurements derived from crest-stage gages in the study reach. Analysis of the longitudinal profiles indicated noticeable changes in the percentage and distribution of riffles, pools, and runs through the study reach between 2002 and 2004. Despite major changes to the channel profile as a result of storm runoff events, the overall slope of the channel bed, water surface, and bank features remained constant at about 1 percent. The cross-sectional surveys showed net increases in cross-sectional area, mean depth, and channel width at several locations between 2002 and 2004, which indicate channel degradation and widening. Two locations were identified where significant amounts of sediment were being stored in the study reach. Data from scour chains identified several locations where maximum scour ranged from 1.0-1.4 feet during storm events. Bank retreat varied widely throughout the study reach and ranged from 0.2 feet to as much as 7.9 feet. Sequential measurements of bed elevation in selected locations indicated as much as 2 feet of channel degradation in one location during a storm event in May 2004 and identified pulses of sediment that were gradually transported through the study reach during the monitoring period. Particle-size analyses of channel bed materials indicated a median particle diameter of 20.5 millimeters (coarse gravel) for the study reach, with more than 24 percent being sand particles (greater than 0.062 millimeters). Analyses of bank samples showed finer-grained material composing the channel banks, predominantly silt/clay or a mixture of silt/clay (less than 0.062 millimeters) and very fine to coarse sand. The Minebank Run stream channel was classified as a B4c channel, based on morphological descriptions from the Rosgen Stream Classification System. The B4c classification describes a single-thread stream channel with a moderate entrenchment ratio of 1.4 to 2.2; a width-to-depth ratio greater than 12; moderate sinuosity of 1.2 or greater; a water-surface slope of less than 2 percent; and a median-particle diameter in the gravel range of 2 to 64 millimeters. Analysis of boundary shear stress indicated larger mean velocities and boundary shear stress values for Minebank Run when compared to relations for non-urban B channel types developed by Rosgen. The slope of the regression line for mean velocity versus boundary shear stress at Minebank Run was considerably less than slopes developed by Rosgen for non-urban channel types. This indicates that relatively small increases in mean velocity can result in large increases in boundary shear stress in stream channels with highly developed watersheds, such as Minebank Run.

    2001-06-01

    The Integrated Management of Childhood Illness (IMCI) strategy combines improved case management of childhood illness with aspects of nutrition, immunization, disease prevention, and promotion of growth and development. The household and community component of IMCI was formulated to reach the numerous sick children who are ill and often die at home without ever being treated by a trained healthcare practitioner. In January 2001, USAID (Child Health Research Project and BASICS II) and the CORE Group sponsored a meeting in Baltimore, Maryland, to determine the research needed to implement household and community IMCI effectively. This paper summarizes the presentations at that meeting and highlights the research and programme priorities expressed using the three-element approach devised by the CORE Group and USAID (BASICS II and Child Survival Technical Support Project). Research priorities to improve partnerships between health facilities and the communities they serve (Element 1) include finding ways to increase community involvement and management of health facilities, establishing accurate costs for community IMCI services, and formulating cost-recovery mechanisms tailored to local circumstances. Programme priorities in Element 1 include establishment of systems for maintenance of an adequate supply of essential equipment and medicines, while retaining access for the poor and ensuring adequate referral mechanisms for severely-ill patients that include monitoring and incentives for the performance of health workers. Research priorities to increase appropriate, accessible care and information from community-based care providers (Element 2) consist of activities to design simplified IMCI guidelines for use by community health workers (CHWs) and volunteers and evaluation of the impact of using these guidelines on morbidity and mortality. Also a priority item in this category is experimenting with ways to teach mothers and families to care for sick children at home and strategies to improve the practice of medicine in the private sector. More research is also needed to improve the quality of nutritional and preventive health counselling given by CHWs and to find ways to make community IMCI interventions sustainable. Programme priorities in Element 2 include efforts at the national level to establish policies to improve care by traditional and private care providers and to define the position of volunteer workers in the national health system. Research priorities to integrate promotion of key family practices critical for public health (Element 3) are focused on determining which interventions are the most effective in reducing child morbidity and mortality at the household and community levels, finding the best methods of delivering these interventions, and implementing these and scaling up in essential service packages. Particular issues in child health, needing urgent attention from the research and programme communities, are HIV/AIDS and neonatal morbidity and mortality. PMID:11503353

    Seventy-five per cent of 845 Norway rats examined in the Baltimore Zoo for Capillaria hepatica were infected. Nearly all adult rats and 65% of juveniles were infected. Only 8% of 299 infected rats were heavily infected. The prevalence and intensity of infection increased with the size of the host. There were no seasonal differences in infection rates among adults, but juveniles collected during spring had higher infection rates than those collected during winter. Prevalence of C. hepatica infection varied from one place to another. No correlation between infection rate, vegetative cover, soil type, monthly rainfall, mean daily temperature, or food habits of rats was found. The dynamics of rat populations are perhaps the most important factors in the maintenance and dynamics of C. hepatica infections. Rapid population turnover contributes to the rapid release of a great number of eggs into the environment and high recruitment rates provide sufficient numbers of susceptible hosts for the parasite to complete its cycle.

    Tobacco use is the largest preventable cause of death in the United States. Associations between cigarette smoking and HIV risk behaviors were examined among 669 injection drug users (IDU) in the 2006 wave of the National HIV Behavioral Surveillance System in Baltimore, Maryland, using respondent-driven sampling. The adjusted prevalence of smoking among IDU was 92.1%, with 32.7% smoking < 1 pack of cigarettes per day (light smoking) and 59.3% smoking ? 1 packs per day (heavy smoking). Self-reported HIV prevalence decreased as smoking frequency increased (p = 0.001). In multivariate analysis, heavy smokers were more likely to report painkiller use and binge drinking and less likely to report anal sex or health care use in the past year than light smokers. Results suggest that health care use mediates the relationship between heavy smoking and self-reported HIV. Integrating smoking cessation with HIV prevention services could address unmet health needs in IDU. PMID:22468974

    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. PMID:25831575

    An ensemble statistical post-processor (ESP) is developed for the National Air Quality Forecast Capability (NAQFC) to address the unique challenges of forecasting surface ozone in Baltimore, MD. 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. Taking advantage of the ESP, the user not only receives an increase in value over the NAQFC, but also receives value for An ensemble statistical post-processor (ESP) is developed for the National Air Quality Forecast Capability (NAQFC) to address the unique challenges of forecasting surface ozone in Baltimore, MD.

    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

  3. Assessing dietary intake among infants and toddlers 0–24 months of age in Baltimore, Maryland, USA

    2013-01-01

    Objective To characterize food and nutrient intake and develop a population-specific food list to be used as a comprehensive dietary assessment tool for Baltimore infants and toddlers aged 0–24 months. The data were used to inform the Growing Leaps and Bounds (GLB) program, which promotes early obesity prevention among Baltimore infants and toddlers. Research methods & procedures A cross-sectional dietary survey using 24-hour recalls among randomly selected primary caregivers of infants and toddlers was conducted. Results Data were collected from 84 children, (response rate 61%) 45 boys; 39 girls. Mean daily energy intakes were 677 kcal, 988 kcal, and 1,123 kcal for children 0–6 months, 7–12 months and 13–24 months, respectively. Infants 0–6 months had higher percentage of energy from fat (48%) than infants 7–12 months (34%) and 13–24 months (31%). Mean daily intakes for all nutrients among 0–12 months old were ≥ Dietary Reference Intakes (DRI), while toddlers 13–24 months had inadequate vitamins A, D, and E intake. Breastfeeding occurred in 33% of infants and toddlers 0 to 6 months, while less than 3% of those aged 7 to 24 months were breastfed. A 104-item food list with eight food and drink categories was developed. Conclusions Infants were formula fed with a higher frequency than they were breastfed. The consumption of high-sugar and high-fat foods (e.g. sweetened drinks, French fries) increased with each age group, which can increase the risk of childhood obesity. PMID:23622709

    A walk-through survey was conducted at three facilities of McCormick and Co., Baltimore, Maryland, to determine the suitability of the company for inclusion in an industrywide mortality and industrial hygiene study of workers potentially exposed to ethylene-oxide (Et0) in industrial-sterilization processes. Ethylene oxide has been used since 1938 to sterilize spices. Industrial hygiene records, production processes, and personnel records were evaluated. The facilities meet the requirements of being able to contribute at least 400 person years of data to the study, having adequate personnel records to identify past and present workers exposed to EtO, and do not have any serious confounding exposure to a known leukemogen, even though some of the workers were exposed during the 1940s and 1950s to a number of toxic chemicals. Methyl bromide has been used as a fumigant in the plant and may have at times been present in low levels in the air. A possible connection between this compound and carcinoma induced experimentally in rats is noted, but the compound is not known to be a leukemogen.

    Background While urban redevelopment is intended to ameliorate urban decay, some studies demonstrate that it can negatively impact some residents. Few studies have considered its impact on persons with a history of drug use. Methods A convenience sample of 25 current or former injection drug users from Baltimore, Maryland, enrolled in the AIDS Linked to the Intravenous Experience study, and reporting residence in or bordering a redeveloping neighborhood participated in 1-2 semi-structured in-depth interviews from July, 2011-February, 2012. Interviews explored personal experiences with redevelopment and perceptions of community-wide impact. Data were analyzed using the constant comparison method. Results Respondents rarely described urban redevelopment as solely negative or positive. Revitalization and increased security in the redeveloping area were reported as positive consequences. Negative consequences included the lack of redevelopment-related employment opportunities, disruption of social ties, and housing instability among relocated residents. Respondents also said that urban redevelopment led to the displacement of drug markets to adjacent neighborhoods and outlying counties. Residential relocation and displacement of drug markets were reported as beneficial for persons in contemplative and later stages of recovery. Conclusion These findings support a holistic approach to urban redevelopment that increases access to employment opportunities and affordable housing and ensures equitable coverage of public services such as law enforcement.

    This study examined correlates of disclosure of MSM behavior and seropositive HIV status to social network members among 187 African American MSM in Baltimore, MD. 49.7% of participants were HIV-positive, 64% of their social network members (excluding male sex partners) were aware of their MSM behavior, and 71.3% were aware of their HIV-positive status. Disclosure of MSM behavior to network members was more frequent among participants who were younger, had a higher level of education, and were HIV-positive. Attributes of the social network members associated with MSM disclosure included the network member being HIV-positive, providing emotional support, socializing with the participant, and not being a female sex partner. Participants who were younger were more likely to disclose their positive HIV status. Attributes of social network members associated with disclosure of positive serostatus included the network member being older, HIV-positive, providing emotional support, loaning money, and not being a male sex partner.

    Stream restoration efforts have been ongoing in Maryland since the early 1990s. Physical stream restoration often involves replacement of lost sediments to elevate degraded streambeds, re-establishment of riffle-pool sequences along the channel profile, planting vegetation in riparian zones, and re-constructing channel banks, point bars, flood plains, and stream-meanders. The primary goal of many restoration efforts is to re-establish geomorphic stability of the stream channel and reduce erosive energy from urban runoff. Monitoring streams prior to and after restoration could help quantify other possible benefits of stream restoration, such as improved water quality and biota. This report presents general watershed characteristics associated with the Minebank Run watershed; a small, urban watershed in the south-central section of Baltimore County, Maryland that was physically restored in phases during 1999, 2004, and 2005. The physiography, geology, hydrology, land use, soils, and pre-restoration geomorphic setting of the unrestored stream channel are discussed. The report describes a reach of Minebank Run that was selected for the purpose of collecting several types of environmental data prior to restoration, including continuous-record and partial-record stage and streamflow data, precipitation, and ground-water levels. Examples of surface-water data that were collected in and near the study reach during water years 2002 through 2004, including continuous-record streamflow, partial-record stage and discharge, and precipitation, are described. These data were used in analyses of several characteristics of surface-water hydrology in the watershed, including (1) rainfall totals, storm duration, and intensity, (2) instantaneous peak discharge and daily mean discharge, (3) stage-discharge ratings, (4) hydraulic-geometry relations, (5) water-surface slope, (6) time of concentration, (7) flood frequency, (8) flood volume, and (9) rainfall-runoff relations. Several hydrologic characteristics that are typical of urban environments were quantified by these analyses. These include (1) large ratios of peak discharge to daily mean discharge as an indicator of flashiness, (2) consistent shifting of the stage-discharge rating over short periods of time that indicates instability of the stream channel, (3) analyses of hydraulic-geometry relations that indicate mean velocities of 11 feet per second or more while the flow is contained in the stream channel, (4) discharges that are 4 to 5 times larger in Minebank Run for corresponding flood frequency recurrence intervals than in Slade Run, which is a Piedmont watershed of similar size with smaller percentages of urban development, and (5) flood waves that can travel through the stream channel at a velocity of 412 feet per minute, or 6.9 feet per second.

    In early 2005, the University of Maryland at Baltimore County Atmospheric Physics Group (http://alg.umbc.edu) took possession of a Depolarization and Backscatter Unattended Lidar (DABUL2) system. This instrument is the second version of this style lidar developed by National Oceanic and Atmospheric Administration (NOAA) Earth System Research Laboratory (ESRL). Over the past 10 years, the original NOAA DABUL lidar has collected data from a variety of locations all over the world from the Western Pacific tropics to the Arctic Ocean. This type of system is capable of continuous, unattended profiling of cloud and aerosol layers throughout the troposphere and into the lower stratosphere. The DABUL2 lidar consists of a pulsed laser source emitting at a wavelength of 532 nm, that is expanded to a 35 cm diameter beam before exiting the instrument. The large diameter beam maximizes eye-safety, resulting in a power density less than commercially available laser pointers and making the system more practical for unattended operations. Adequate signal-to-noise performance is achieved using a receiver with a narrow field- of-view (FOV), 0.4 nm bandpass filtering, and a high laser pulse repetition rate (2 kHz) to maximize signal averaging for a given time interval. Backscatter polarization properties are obtained by pulse-to-pulse alternating the polarization state of the outgoing laser beam with a Pockels cell and synchronously detecting the range-gated backscatter intensity from the atmosphere. The first measurements obtained at UMBC with the DABUL2 system occurred during spring of 2005. Data were recorded over several days during a variety of cloud and no-cloud conditions, both during day and nighttime background levels. Time coincident lidar data were also compared to a Micro-Pulse Lidar (MPL) system operating 40 km to the southwest, at the NASA Goddard Space Flight Center. The MPL system did not have depolarization capability, but provided elastic scattering measurements that are useful for cross- calibration between the two instruments, as well providing insight into the spatio-temporal evolution of cloud and aerosol layers for regional-scale spatial distances. An analysis of time-coincident cirrus data for a particular case on 30 March 2005 showed a relatively high degree of correlation in cloud structure appearance, despite the significant distance between lidar measurements. Results from this comparison as well as other time-correlated data will be presented. In conjunction with wind trajectory information, multi-point UMBC/DABUL and GSFC/MPL measurements can help to better define spatial variability for different cloud and aerosol features for interpreting satellite data. With two simultaneous lidar measurements separated by 40 km, data from the UMBC/DABUL and GSFC/MPL locations will help assess the spatio-temporal representativeness of cloud features for CALIPSO overpasses in the Washington-Baltimore region and contribute to related trajectory modeling efforts. Furthermore, the depolarization capability of the DABUL2 system will further extend UMBC's role in helping to interpret CALIPSO data.

    Background Syringe distribution policies continue to be debated in many jurisdictions throughout the U.S. The Baltimore Needle and Syringe Exchange Program (NSP) operated under a 1-for-1 syringe exchange policy from its inception in 1994 through 1999, when it implemented a restrictive policy (2000–2004) that dictated less than 1-for-1 exchange for non-program syringes. Methods Data were derived from the Baltimore NSP, which prospectively collected data on all client visits. We examined the impact of this restrictive policy on program-level output measures (i.e., distributed:returned syringe ratio, client volume) before, during, and after the restrictive exchange policy. Through multiple logistic regression, we examined correlates of less than 1-for-1 exchange ratios at the client-level before and during the restrictive exchange policy periods. Results During the restrictive policy period, the average annual program-level ratio of total syringes distributed:returned dropped from 0.99 to 0.88, with a low point of 0.85 in 2000. There were substantial decreases in the average number of syringes distributed, syringes returned, the total number of clients, and new clients enrolling during the restrictive compared to the preceding period. During the restrictive period, 33,508 more syringes were returned to the needle exchange than were distributed. In the presence of other variables, correlates of less than 1-for-1 exchange ratio were being white, female, and less than 30 years old. Discussion With fewer clean syringes in circulation, restrictive policies could increase the risk of exposure to HIV among IDUs and the broader community. The study provides evidence to the potentially harmful effects of such policies. PMID:25919590

    In many older US cities, lead (Pb) contamination of residential soil is widespread; however, contamination is not uniform. Empirically based, spatially explicit models can assist city agencies in addressing this important public health concern by identifying areas predicted to exceed public health targets for soil Pb contamination. Sampling of 61 residential properties in Baltimore City using field portable X-ray fluorescence revealed that 53 % had soil Pb that exceeded the USEPA reportable limit of 400 ppm. These data were used as the input to three different spatially explicit models: a traditional general linear model (GLM), and two machine learning techniques: classification and regression trees (CART) and Random Forests (RF). The GLM revealed that housing age, distance to road, distance to building, and the interactions between variables explained 38 % of the variation in the data. The CART model confirmed the importance of these variables, with housing age, distance to building, and distance to major road networks determining the terminal nodes of the CART model. Using the same three predictor variables, the RF model explained 42 % of the variation in the data. The overall accuracy, which is a measure of agreement between the model and an independent dataset, was 90 % for the GLM, 83 % for the CART model, and 72 % for the RF model. A range of spatially explicit models that can be adapted to changing soil Pb guidelines allows managers to select the most appropriate model based on public health targets. PMID:23775390

    STEP into Action assessed the efficacy of a peer-based HIV prevention intervention in reducing HIV risk behaviors among people who inject drugs (PWIDs) in Baltimore. This analysis examined the effect of the intervention on the change in frequency of conversation about HIV prevention topics over time. 114 participants were randomized into an experimental and 113 into a control group. Data was collected prospectively at 6, 12, and 18 months. The experimental group talked more frequently about HIV prevention topics compared to the control group at 6-month visit. At 18 months relative risk ratios (RRR) remained statistically significant for conversation about the danger of needle sharing (RRR = 3.21) and condom use (RRR = 2.81). The intervention resulted in an increased conversation about HIV prevention among PWIDs, but the sustainability past 6 months remained a challenge; suggesting that interventions should be designed to constantly reinforce communication about HIV prevention among PWIDs.

    Background: There has been limited research regarding the Supplemental Nutritional Assistance Program (SNAP) and recipients’ dietary quality during the days and weeks after benefit disbursement. Objective: We examined the relation between participants’ stages in the SNAP cycle and their macronutrient consumption, Healthy Eating Index (HEI) scores, and fruit and vegetable intake. Design: In this cross-sectional study, we analyzed single 24-h dietary recalls collected from 244 African American SNAP participants recruited near 24 corner stores in Baltimore City. A multiple linear regression analysis and bootstrapping were used. Results: Among participants who received a SNAP benefit ≤15 d before being surveyed, energy intake adjusted for minimum energy requirements (−4.49%; 95% CI: −8.77%, −0.15%) and HEI dairy scores (−0.12; 95% CI: −0.22, −0.01) were lower for each 1-d increase in the time since SNAP distribution (TSSD). Among participants who received SNAP benefits >15 d before being surveyed, energy intake (1.35%; 95% CI: 0.01%, 2.73%), energy intake adjusted for minimum energy requirements (3.86%; 95% CI: 0.06%, 7.96%), total fat intake (1.96%; 95% CI: 0.29%, 3.8%), saturated fat intake (2.02%; 95% CI: 0.23%, 4.01%), and protein intake (2.09%; 95% CI: 0.70%, 3.62%) were higher per each 1-d increase in the TSSD. Conclusions: These findings suggest that the relation between the TSSD and macronutrient intake might be U-shaped, with higher intake of calories, fat, and protein in individuals in the very early and late stages of their SNAP cycles. Foods high in these nutrients might be cheaper, more accessible, and have a longer shelf-life than healthier options, such as fruit, vegetables, and whole grains, for SNAP participants when their benefits run out. Additional efforts are needed to investigate the effect of the TSSD on dietary intake by using a longitudinal design and to improve the quality of dietary intake in African American SNAP participants.

  16. 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.

    Cleveland, Angela Ahlquist; Farley, Monica M.; Harrison, Lee H.; Stein, Betsy; Hollick, Rosemary; Lockhart, Shawn R.; Magill, Shelley S.; Derado, Gordana; Park, Benjamin J.; Chiller, Tom M.

    2015-01-01

    Background Candidemia is common and associated with high morbidity and mortality; changes in population-based incidence rates have not been reported. Methods We conducted active, population-based surveillance in metropolitan Atlanta, Georgia, and Baltimore City/County, Maryland (combined population 5.2 million), during 2008–2011. We calculated candidemia incidence and antifungal drug resistance compared with prior surveillance (Atlanta, 1992–1993; Baltimore, 1998–2000). Results We identified 2675 cases of candidemia with 2329 isolates during 3 years of surveillance. Mean annual crude incidence per 100 000 person-years was 13.3 in Atlanta and 26.2 in Baltimore. Rates were highest among adults aged ≥65 years (Atlanta, 59.1; Baltimore, 72.4) and infants (aged <1 year; Atlanta, 34.3; Baltimore, 46.2). In both locations compared with prior surveillance, adjusted incidence significantly declined for infants of both black and white race (Atlanta: black risk ratio [RR], 0.26 [95% confidence interval {CI}, .17–.38]; white RR: 0.19 [95% CI, .12–.29]; Baltimore: black RR, 0.38 [95% CI, .22–.64]; white RR: 0.51 [95% CI: .29–.90]). Prevalence of fluconazole resistance (7%) was unchanged compared with prior surveillance; 32 (1%) isolates were echinocandin-resistant, and 9 (8 Candida glabrata) were multidrug resistant to both fluconazole and an echinocandin. Conclusions We describe marked shifts in candidemia epidemiology over the past 2 decades. Adults aged ≥65 years replaced infants as the highest incidence group; adjusted incidence has declined significantly in infants. Use of antifungal prophylaxis, improvements in infection control, or changes in catheter insertion practices may be contributing to these declines. Further surveillance for antifungal resistance and efforts to determine effective prevention strategies are needed. PMID:22893576

  16. 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.

  11. Marylanders defeat Philadelphia: yellow fever updated.

    PubMed Central

    Woodward, T. E.; Beisel, W. R.; Faulkner, R. D.

    1976-01-01

    Those strategic points which influence this amateur historian to declare a victory for Baltimore and Maryland over Philadelphia are: I. Based upon clinical and epidemiological data, two Marylanders, Potter and Davidge, were among the first to contest Rush and his contagion theory; they told him so and published their views. To prove this point, Potter went to the extreme of inoculating himself with presumedly infected material. Stubbins Ffirth, a young University of Pennsylvania medical student, did the same four years later. To Rush's credit was ultimate abandonment of his originally held views. II. John Crawford, of Baltimore, although not the originator of the insect concept of transmission of infectious agents, published his concepts in 1811. III. Henry Rose Carter, a Maryland graduate, clearly delineated, in 1898, that after identification of an index case of yellow fever an extrinsic incubation period was necessary before the evolution of secondary cases. IV. James Carroll, another University of Maryland graduate, who worked as Deputy under Walter Reed with Lazear and Agramonte, helped prove Finlay's original concept that the Aedes aegypti mosquito was the natural vector of yellow fever. Carroll himself was the first experimentally induced case. V. Studies in primates provide new approaches for management of yellow fever. Nutritional support and treatment with specific anti-viral agents may be useful for therapy of human yellow fever. Maryland members of the Climatological are mindful of Philadelphia's rich medical heritage and of the many battles won in the City of Brotherly Love. Physicians in colonial and early America experienced The best and worst of times, theirs was an age of foolishness and belief, of incredulity and light, of darkness, despair and hope.

  1. Challenges in Urban Hydrologic Modeling: A Baltimore Case Study

    NASA Astrophysics Data System (ADS)

    Bhaskar, A.; Welty, C.; Maxwell, R. M.

    2009-05-01

    To effectively and sustainably manage water resources in urban areas we need to better understand the effects of urbanization on the hydrologic cycle and conversely, the ways that surface and groundwater quality and quantity can affect humans. We present work on coupled modeling groundwater and surface water in Dead Run, a small urban watershed in Baltimore, Maryland. We use ParFlow, which models three dimensional, variably saturated subsurface - surface flow. This poster reviews some of the challenges that have been encountered in modeling elevations and slopes for overland flow in the Dead Run case. Elevations from a Digital Elevation Model (DEM) in an urban landscape may not be able to adequately define surface flow paths as streams may have been moved, channelized, piped underground, or otherwise modified. Knowledge of the locations of streams may not be adequate, as the surface stream expressions may be disconnected due to piping in between. Here we present the beginnings of ways to deal with the challenges of modeling urban as well as future plans to incorporate urbanization within existing models. This work will be expanded to a regional hydrologic model, which will be coupled with an urban growth model of the Baltimore region to explore the predictions and feedbacks between the two models.

    After thirty years at the U.S. National Cancer Institute (NCI), Robert Gallo, M.D., is leaving to start the Institute of Human Virology, which will be part of the University of Maryland system. The Institute will focus on AIDS, but will also do research in other human viral diseases and in cancer. The Institute's initial funding, $16 million, is from the state, the University of Maryland, the city of Baltimore, and other sources. Gallo hopes the Institute will grow from a staff of 50 to a staff of 250 with an annual budget of $30 million. A major focus will be on basic research, primarily to develop better therapies--specifically gene therapy, antisense, and hormonal control. Gallo, program director of basic research, will share leadership with William Blattner, M.D. in epidemiology, and Robert Redfield, M.D. in clinical research. Gallo also hopes to start a biotechnology company, to be called Virex, which will allow new discoveries to move immediately into drug development. The Institute is slated to begin operations this Fall. PMID:11362512

    2000-03-01

    Baltimore-based Planned Parenthood of Maryland and the Baltimore City Health Department have joined forces in "EC to Go," which distributes free emergency contraceptive pills (ECPs) through the seven affiliate sites of Planned Parenthood and the three family planning centers of the city. The distribution program was started in October 1999 and funds were provided by an undisclosed area foundation. Although the program is still in its infancy, it has recorded some 800 prescriptions of ECPs in the last fiscal year, and 600 prescriptions have been logged in just the first 6 months of the current fiscal year. To inform the public about the program, Planned Parenthood developed newspaper advertisements, a 60-second radio spot, and coupon distributions, all of which emphasize the fact that emergency contraception is a higher dose of birth control, which can prevent pregnancy if taken within 72 hours of unprotected sex.

  17. Baltimore City adopts a proactive approach to zebra mussel control using potassium permanganate

    SciTech Connect

    Balog, G.G.; Neimery, T.F.; Davis, L.S.

    1995-06-01

    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.

  20. Modeling ozone episodes in the Baltimore-Washington region

    NASA Technical Reports Server (NTRS)

    Ryan, William F.

    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.

    1989-01-01

    This report presents groundwater withdrawal data from 1900 through 1980 for Maryland counties lying with the Coastal Plain physiographic province, as well as a summary section for the total Maryland Coastal Plain. The types of water use included are domestic, military, water supplier, industrial/commercial, and irrigation. The data were obtained from state and county reports, biannual pumpage reports submitted to the Maryland Water Resources Administration, communication with individual owners, and estimates based on existing published data. The amount of groundwater withdrawn from aquifers in the Maryland Coastal Plain in 1900 was approximately 26 million gallons per day (Mgal/d) compared to nearly 134 Mgal/d in 1980. Jurisdictions withdrawing more than 10 Mgal/d for most of the 80-year period were Anne Arundel and Baltimore Counties and Baltimore City. The greatest withdrawals for most of the early part of the period were for domestic and industrial/commercial uses; however, water-supplier use dominated after 1965. Groundwater use for irrigation became important in the Coastal Plain around 1960 and increased steadily from approximately 2 Mgal/d in 1960 to nearly 12 Mgal/d in 1980. (USGS)

    2008-01-01

    We investigated regional effects of urbanization and land use change on nitrate concentrations in approximately 1,000 small streams in Maryland during record drought and wet years in 2001-2003. We also investigated changes in nitrate-N export during the same time period in 8 intensively monitored small watersheds across an urbanization gradient in Baltimore, Maryland. Nitrate-N concentrations in Maryland were greatest in agricultural streams, urban streams, and forest streams respectively. During the period of record drought and wet years, nitrate-N exports in Baltimore showed substantial variation in 6 suburban/urban streams (2.9-15.3 kg/ha/y), 1 agricultural stream (3.4-38.9 kg/ha/y), and 1 forest stream (0.03-0.2 kg/ ha/y). Interannual variability was similar for small Baltimore streams and nearby well-monitored tributaries and coincided with record hypoxia in Chesapeake Bay. Discharge-weighted mean annual nitrate concentrations showed a variable tendency to decrease/increase with changes in annual runoff, although total N export generally increased with annual runoff. N retention in small Baltimore watersheds during the 2002 drought was 85%, 99%, and 94% for suburban, forest, and agricultural watersheds, respectively, and declined to 35%, 91%, and 41% during the wet year of 2003. Our results suggest that urban land use change can increase the vulnerability of ecosystem nitrogen retention functions to climatic variability. Further work is necessary to characterize patterns of nitrate-N export and retention in small urbanizing watersheds under varying climatic conditions to improve future forecasting and watershed scale restoration efforts aimed at improving nitrate-N retention. ?? 2008 American Chemical Society.

    PROMISE: Maryland's Alliance for Graduate Education and the Professoriate (AGEP), sponsored by the National Science Foundation, is a consortium that is designed to increase the numbers of underrepresented minority (URM) PhDs in science, technology, engineering, and mathematics fields who will pursue academic careers. A strength of PROMISE is its alliance infrastructure that connects URM graduate students on different campuses through centralized programming for the three research universities in Maryland: the University of Maryland Baltimore County (the lead institution in the alliance), the University of Maryland College Park, and the University of Maryland Baltimore (UMB). PROMISE initiatives cover graduate student recruitment, retention, community building, PhD completion, and transition to careers.Although it is not a fellowship, PROMISE offers professional development and skill-building programs that provide academic and personal support for URM students on all three campuses. PROMISE on UMB's campus includes the School of Medicine, which sponsors tricampus programs that promote health and wellness to accompany traditional professional development programs. PROMISE uniquely and atypically includes a medical school within its alliance. The PROMISE programs serve as interventions that reduce isolation and facilitate degree completion among diverse students on each campus. This article describes details of the PROMISE AGEP and presents suggestions for replicating professional development programs for URMs in biomedical, MD/master's, and MD/PhD programs on other campuses.

  18. Organochlorine pesticide residues in moths from the Baltimore, MD-Washington, DC area

    USGS Publications Warehouse

    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.

    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).

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

    NASA Astrophysics Data System (ADS)

    Smith, B. K.; Smith, J. A.; Baeck, M. L.; Villarini, G.

    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.

Approximately 16% (n=84) of the total sample (N=515) reported using diverted (street) methadone 2–3 times per week for six months or more, and for an average of 7.8 days (SD=10.3) within the past month. The group reporting lifetime use of diverted methadone as compared to the group that did not report such use was less likely to use heroin and cocaine in the 30 days prior to admission (ps < .01) and had lower ASI Drug Composite scores (p < .05). Participants in our qualitative sub-sample (n=22) indicated that street methadone was more widely used than street buprenorphine and that both drugs were largely used as self-medication for detoxification and withdrawal symptoms. Participants reported using low dosages and no injection of either medication was reported. PMID:19874152

    Background Selling of single cigarettes, also known as loosies, is a public health concern. Loosies allow for those with fewer resources to buy cigarettes without having to purchase a pack. Selling of loosies may cue smoking behaviors. In the US, socioeconomically disadvantaged populations have high rates of smoking and illicit drug use and the selling of loosies appears to be linked to the urban informal economy. We examined the proportion and frequency of cigarette selling and roles in the informal economy associated with selling loosies among a sample of urban drug users. Methods There were 801 participants, recruited by community outreach, assessed at baseline, who were enrolled in an HIV prevention intervention for drug users. Results Most (89%) smoked cigarettes in the prior 30 days, of whom 92% smoked daily. Self-reported selling of cigarettes was common with 58% reporting that they had sold cigarettes within the last six months; 20.4% reported selling cigarettes a few times a week and 7.4% reported daily selling of cigarettes. In a stepwise regression model, four sources of income were associated with frequent cigarette selling: providing street security (OR=2.214, 95% CI 1.1774.164), selling food stamps (OR=1.461, 95% CI 1.0032.126), pawning items (OR=2.15, 95% CI 1.4753.135), and selling drugs (OR=1.634, 95% CI 1.0082.648). Conclusion There is a high rate of selling loosies among urban substance users. The wide availability of loosies may promote smoking. Smoking cessation programs with drug treatment and economic development programs may help to reduce economic pressures to sell loosies. PMID:23578589

    Objectives: To examine the sex specific seroprevalence and correlates of herpes simplex virus 2 (HSV-2) and syphilis among a cohort of young drug users. Methods: Drug users aged 15–30 years old who used heroin, cocaine, or crack were recruited between October 1999 and August 2002. Baseline interviews gathered information on sociodemographics, drug use and sexual behaviours. Serum was tested at baseline for HSV-2 and syphilis seroreactivity. For each sexually transmitted infection (STI), infected and non-infected participants were stratified by sex and compared using χ2, Mann-Whitney tests, and logistic regression. Results: Of the 543 participants recruited, 42.4% were female and 39.3% were African-American. The seroprevalence of STIs among females and males, respectively, were HSV-2: 58.7% and 22.0%; syphilis: 4.3% and 0.3%. In multivariate models, older age, African-American race, having over 30 lifetime sex partners, current HIV infection and previous incarceration were independently associated with HSV-2 infection among males. For females, older age, African-American race, sex trade, and daily heroin use were independently associated with HSV-2. For females, only a self reported previous syphilis diagnosis was associated with current syphilis seroreactivity in multivariate analyses. Conclusions: Examination of this cohort revealed a particularly high seroprevalence of HSV-2 and syphilis, especially among female drug users. Few infected participants had been previously diagnosed with these infections. PMID:15923296

    The author has identified the following significant results. Capabilities of Skylab photographic data suggest significant applications for: (1) identification and mapping of all primary, most secondary, and many tertiary land use classes; (2) stratification of the landscape for more detailed sampling; and (3) rapid updating of existing land use and vegetation maps subscaled at 1:25,000 and smaller with manual interpretation techniques. Automated thematic mapping of land use categories with electronic data processing techniques is feasible with the S-192 multispectral scanner, despite the high noise levels in many channels.

    This study utilized multilevel cross-classified models to longitudinally assess the association between neighborhood residential rehabilitation and injection drug use. We also assessed whether relocating between neighborhoods of varying levels of residential rehabilitation was associated with injection drug use. Residential rehabilitation was categorized into three groups (e.g. low, moderate, high), and lagged one visit to ensure temporality. After adjusting for neighborhood and individual-level factors, residence in a neighborhood with moderate residential rehabilitation was associated with a 23% reduction in injection drug use [AOR=0.77; 95% CI (0.67,0.87)]; residence in a neighborhood with high residential rehabilitation was associated with a 26% reduction in injection drug use [AOR=0.74; 95% CI (0.61,0.91)]. Continuous residence within neighborhoods with moderate/high rehabilitation, and relocating to neighborhoods with moderate/high rehabilitation, were associated with a lower likelihood of injection drug use. Additional studies are needed to understand the mechanisms behind these relationships. PMID:24840154

    A gas distribution looping project, in three segments that traversed a complete range of installation and alignment issues, recently was completed by Baltimore Gas and Electric Co. (BG and E) in northern Maryland. The major projects unit in the company`s gas system engineering and design section was responsible for total oversight of the three projects. This included design, engineering, permitting, right-of-way acquisition, construction, testing and restoration, as well as liaison with other company divisions. A specially selected subcontractor team was organized to provide the latest technology. A project management system, comprised mainly of personal computer applications, was implemented to provide: engineering and design coordination; accurate interface among easement, real estate acquisition data, plats, surveys, permitting and design documents; accurate right-of-way identification; data storage and accessibility of all real estate information for use in design and budgeting; an interface of environmental conditions with topography and design; a computer database that is compatible with existing computer libraries and industry-available software, for producing drawings. Controls for projects costs, budget and schedule were provided by the project management system. This was accomplished by interaction of four data systems: real estate, accounting/budget, geographical information system (GIS), global positioning system (GPS). Construction progress was monitored with a scheduling application that ultimately provided justification for contractor progress payments. The amount of pipe laid in any given time span, as documented by field inspector reports, was entered into the scheduling application. The scheduling software calculated the percent completed and provided information for monitoring progress.

    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.

    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 components of smaller transportation packages resembling the NAC Model No. LWT, despite placement within an ISO container, could degrade. USNRC staff evaluated the radiological consequences of the package responses to the Baltimore tunnel fire. Though components in some packages heated up beyond their service temperatures, the staff determined that there would be no significant dose as a result of the fire for any of these and similar packages.

  6. Interorganizational relationships among HIV/AIDS service organizations in Baltimore: a network analysis.

    2001-09-01

    A wide variety of organizations has become involved in providing medical and social services to people living with human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS). Although there is much interest among policymakers, service providers, and clients in coordination among HIV/AIDS service organizations, few studies have used network analytic tools to examine existing systems of HIV-related care. In an effort to fill this gap, this study used network analysis methods to describe several aspects of the interorganizational relationships among 30 HIV/AIDS service agencies in Baltimore, Maryland. Client referrals to other organizations, client referrals from other organizations, exchange of information about shared clients, formal written linkage agreements for client referrals, and joint programs were each examined as a distinct type of network tie, with each the basis of a separate network among these 30 organizations. All of the networks except the one based on joint programs were relatively well connected, with most organizations either directly or indirectly linked. Most of the interorganizational collaboration occurred on a rather ad hoc basis for the purposes of meeting the more immediate needs presented by clients. Highly structured coordination involving substantial investment of resources and ongoing interagency activities appeared to be less common. The findings from this study also suggest that the providers in Baltimore tend to work directly with others as client needs arise rather than negotiating through "clearinghouse" types of organizations. Of the 30 HIV/AIDS service organizations, 5 were highly central in at least four of the five different types of networks. These five organizations--each having a critical role in the continuum of care--may be considered the most central core of the HIV/AIDS service delivery network in Baltimore. These organizations tend to be those that have been created specifically to provide HIV-related services or that specialize in HIV/AIDS care. This research can help policymakers understand how an HIV-related service delivery network may function and delineate key features of a network. In all communities, this type of assessment is critical to designing interventions to promote collaboration that are feasible within the context of existing interorganizational relationships. This type of data also has implications for informing activities to build the capacity of HIV/AIDS service organizations. PMID:11564850

    Personal exposures to particulate and gaseous pollutants and corresponding ambient concentrations were measured for 56 subjects living in Baltimore, Maryland, and 43 subjects living in Boston, Massachusetts. The 3 Baltimore cohorts consisted of 20 healthy older adults (seniors), 21 children, and 15 individuals with physician-diagnosed chronic obstructive pulmonary disease (COPD*). The 2 Boston cohorts were 20 healthy seniors and 23 children. All children were 9 to 13 years of age; seniors were 65 years of age or older; and the COPD participants had moderate to severe physician-diagnosed COPD. Personal exposures to particulate matter with aerodynamic diameters less than 2.5 microm (PM2.5), sulfate (SO(4)2-), elemental carbon (EC), ozone (03), nitrogen dioxide (NO2), and sulfur dioxide (SO2) were measured simultaneously for 24 hours/day. All subjects were monitored for 8 to 12 consecutive days. The primary objectives of this study were (1) to characterize the personal particulate and gaseous exposures for individuals sensitive to PM health effects and (2) to assess the appropriateness of exposure assessment strategies for use in PM epidemiologic studies. Personal exposures to multiple pollutants and ambient concentrations were measured for subjects from each cohort from each location. Pollutant data were analyzed using correlation and mixed-model regression analyses. In Baltimore, personal PM2.5 exposures tended to be comparable to (and frequently lower than) corresponding ambient concentrations; in Boston, the personal exposures were frequently higher. Overall, personal exposures to the gaseous pollutants, especially O3 and SO2, were considerably lower than corresponding ambient concentrations because of the lack of indoor sources for these gases and their high removal rate on indoor surfaces. Further, the impact of ambient particles on personal exposure (the infiltration factor) and differences in infiltration factor by city, season, and cohort were investigated. No difference in infiltration factor was found among the cohorts, which suggests that all subjects were exposed to the same fraction of ambient PM2.5 for a given ambient concentration. In addition, the results show significant correlations between ambient PM2.5 concentrations and corresponding personal exposures over time and provide further indication that ambient gaseous pollutant concentrations may be better surrogates for personal PM2.5 exposures, especially personal exposures to PM2.5 of ambient origin, than their respective personal exposures. These results have important implications for PM health effects studies that use regression models including both ambient PM2.5 and gaseous pollutant concentrations as independent variables, because both parameters may be serving as surrogates for PM2.5 exposures.

    We have deployed Satlantic SUNA optical nitrate sensors and YSI specific conductivity and temperature sensors at 6 USGS stream monitoring stations in a nested watershed design within Dead Run watershed, a highly urbanized catchment in Baltimore County, Maryland, USA, where long-term weekly sampling is also conducted for the Baltimore long-term ecological research (LTER) project. Data are collected every 30 minutes and transmitted to a central location via cellular modem. We have developed web services to enable near-real-time viewing of the data by project personnel from any location. Data from high frequency sensors show patterns and trends that are not discernible from weekly sampling, such as diurnal signals in nitrate and specific conductance observed at base flow and constant discharge. Nitrate exhibits a strong diurnal signal with mean concentrations ranging from 1 to 2 mg/L, with higher concentrations observed in headwater streams. Specific conductance has a wavelength similar to the nitrate signal, with values ranging from 1 to 1.5 mS/cm. During storm events both nitrate and specific conductance are diluted with minimum concentrations occurring at peak stream discharge. As streams recover both nitrate and specific conductance return to pre-storm conditions and the diurnal signals reappear. For storm events, a mixing model can be applied to the specific conductance data to infer old water contributions to stream discharge as a function of scale. Comparing storms across nested watersheds shows that first-order watersheds produce the highest fraction of old water, and that the fraction of old water contribution decreases with increasing watershed scale. Old water contributions increase with decreasing storm size at all watershed scales, with an old water contribution as high as 70 percent in headwater streams for small storms. We have also applied spectral analysis to the high frequency sensor data to compare to the 13-year weekly data record by the Baltimore LTER. Spectral analysis shows that fractal scaling is observed for both weekly and high frequency data and that the nitrate data exhibit the same fractal slope across all frequencies.

  9. Untangling the effects of urban development on subsurface storage in Baltimore

    2015-02-01

    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.

    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. PMID:26526242

    Improvements to hydrologic modeling of urban watersheds are necessary to improve flash flood forecasting, flood hazard assessment, and urban planning. We use the Gridded Surface/ Subsurface Hydrologic Analysis (GSSHA) model to represent the 14.3 square kilometer Dead Run watershed in Baltimore County Maryland. Dead Run is a flashy watershed with extremely high runoff ratios. We strive to represent the watershed with a physically-based watershed model and as little calibration as possible. GSSHA is a gridded model with 2-D overland flow and 1-D stream flow and infiltration processes. Significant efforts are made to accurately represent the effects of detention infrastructure, storm drains, and urban soils within the watershed. High resolution, spatially distributed, Hydro-NEXRAD rainfall fields are used to drive the model, and comparisons are made with a network of rain gages. We utilize USGS instantaneous streamflow data for the watershed outlet and five sub-watershed gaging sites to compare to model output. These nested gaging sites allow us to assess the model's performance throughout the watershed and to ensure that the hydrologic processes in each of the different sub-basins are properly captured.

    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.

    On Sunday, April 28, a category F5 tornado cut an East-West path through La Plata, Maryland, killing 5 and injuring more than 100. These two images acquired by NASA's Terra satellite Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) show a 6-by-17.8-kilometer (3.7-by-11.1-mile) area centered on the town. The top image was acquired on May 12, 2001, and the bottom on May 3, 2002. The bands used for the image portray vegetation in red, and bare fields and urban areas in blue-green. The dark turquoise swath cutting across the 2002 image is the track of the tornado, where the vegetation was ripped up and removed.

    With its 14 spectral bands from the visible to the thermal infrared wavelength region, and its high spatial resolution of 15 to 90 meters(about 50 to 300 feet), ASTER will image Earth for the next six years to map and monitor the changing surface of our planet.

    ASTER is one of five Earth-observing instruments launched December 18,1999, on NASA's Terra satellite. The instrument was built by Japan's Ministry of Economy, Trade and Industry. A joint U.S./Japan science team is responsible for validation and calibration of the instrument and the data products. Dr. Anne Kahle at NASA's Jet Propulsion Laboratory, Pasadena, Calif., is the U.S. science team leader; Bjorn Eng of JPL is the project manager. The Terra mission is part of NASA's Earth Science Enterprise, a long-term research effort dedicated to understanding and protecting our home planet. Through the study of Earth, NASA will help to provide sound science to policy and economic decision makers so as to better life here, while developing the technologies needed to explore the universe and search for life beyond our home planet.

    The broad spectral coverage and high spectral resolution of ASTER will provide scientists in numerous disciplines with critical information for surface mapping and monitoring dynamic conditions and temporal change. Example applications are: monitoring glacial advances and retreats; monitoring potentially active volcanoes; identifying crop stress; determining cloud morphology and physical properties; evaluating wetlands; monitoring thermal pollution; monitoring coral reef degradation; mapping surface temperatures of soils and geology; and measuring surface heat balance.

    2005-05-01

    Diarrheagenic Escherichia coli, which may include the enteropathogenic E. coli and the enterohemorrhagic E. coli, are a significant cause of diarrheal disease among infants and children in both developing and developed areas. Disease outbreaks related to freshwater exposure have been documented, but the presence of these organisms in the urban aquatic environment is not well characterized. From April 2002 through April 2004 we conducted weekly surveys of streams in the metropolitan Baltimore, Md., area for the prevalence of potentially pathogenic E. coli by using PCR assays targeting the tir and stx(1) and stx(2) genes. Coliforms testing positive for the presence of the tir gene were cultured from 653 of 1,218 samples (53%), with a greater prevalence associated with urban, polluted streams than in suburban and forested watershed streams. Polluted urban streams were also more likely to test positive for the presence of one of the stx genes. Sequence analysis of the tir amplicon, as well as the entire tir gene from three isolates, indicated that the pathogenic E. coli present in the stream waters has a high degree of sequence homology with the E. coli O157:H7 serotype. Our data indicate that pathogenic E. coli are continually deposited into a variety of stream habitats and suggest that this organism may be a permanent member of the gastrointestinal microflora of humans and animals in the metropolitan Baltimore area.

    The Baltimore Memory Study is a cohort study of the multilevel determinants of cognitive decline in 50-70-year-old randomly selected residents of specific city neighborhoods. Prior studies have demonstrated that cognitive function differs by race/ethnicity, with lower scores in minorities than in whites, but the underlying basis for these differences is not understood. Studies have differed in the rigor with which they evaluated and controlled for such important confounding variables as socioeconomic status (SES), health-related behaviors, comorbid illnesses, and factors in the physical environment. The goal of this study was to describe differences in neurobehavioral test scores by race/ethnicity, before and after control for a four-dimensional measure of SES and health-related behaviors and health conditions, in a cross-sectional analysis of first visit data. Random samples of households in the study area were selected until enrollment goals were reached. Among the 2,351 persons on whom eligibility was determined, 60.8% were scheduled for an enrollment visit; of these, 1,140 (81.3%) were enrolled and tested. These study participants were 34.3% male and 65.7% female and were from 65 Baltimore, Maryland, neighborhoods. After adjustment for age, sex, and testing technician, there were large and statistically significant differences in neurobehavioral test scores by race/ethnicity, with African-American scores lower than those for whites, for both men and women. After adjustment for individual SES (educational status, household income, household assets, and occupational status), the average difference declined by 25.8%. After additional adjustment for SES, health-related behaviors and health conditions, and blood lead, the average difference declined another 10%, but large differences persisted; African Americans had test scores that averaged 0.43 standard deviation lower than those for whites across all neurobehavioral tests. These differences were present in all cognitive domains, including tests that would not be characterized as susceptible to differential item functioning by race/ethnicity, suggesting that the results are not due to race/ethnicity-associated measurement error.

    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 measurements were conducted on days when severe ozone pollution was forecasted, and these results represent the decreasing trend in high ozone events over the past 15 yr. Back trajectory cluster analysis demonstrates that emissions of air pollutants from Ohio and Pennsylvania through Maryland influence the column abundances of downwind ozone in the lower atmosphere. The trends in air pollutants reveal the success of regulations implemented over the past decades and the importance of region-wide emission controls in the eastern United States.

  2. Metropolitan Lima: area profile.

    Hakkert, R

    This profile of metropolitan Lima, Peru, covers administrative divisions; population growth; age distribution; ethnicity and religion; housing and households; education and health care; economic activity, income, and consumption; transport and communication; and sources of information. Nearly 30% of Peru's entire population and 42% of its urban population live in Lima. The trend continues, yet Lima's urban primacy is waning due to the growth of some regional centers like Trujillo and Chimbote. Lima is still almost 10 times as large as the country's next ranking cities, Trujillo on the northern coast and Arequipa in the south. Peru's main administrative divisions are the 24 departments, of which the Department of Lima is one. These departments are further divided into 156 provinces. Greater Lima consists of 2 such provinces, the province of Lima and the constitutional province of Callao. Although the population of Lima continues to grow, its rate of growth slowed from about 5.5% during the 1960s to about 3.9% in the 1970s. Current projections estimate a metropolitan population of 6.7 million by 1990. On the whole, Lima's age structure is somewhat older than that of the rest of Peru. The median age of the population is 22.3 years, compared to a national figure of 20.4. The proportion of persons over age 65 is only 3.6%, lower than the national average of 4.1%, due to the tendency of in-migration to concentrate people of intermediate ages in the cities. Almost 400,000 inhabitants of greater Lima are bilingual in Spanish and an indigenous language. As elsewhere in Peru, the dominant religion is Roman Catholicism. Lima is a spread out city with few high rise buildings due to the danger of earthquakes. Only 12% of Lima's households are found in apartment buildings. As in other cities of Latin America, the formal housing market is beyond the reach of a major segment of the population. Consequently, much of the urban settlement has occurred through informal self-help construction. Only 2.7% of the metropolitan population over age 15 is illiterate, down from 5.4% in 1972 and 7.7% in 1961. In 1981 Lima had 93 hospitals with a total of 12,640 beds. In addition there were 102 health centers and 10 sanitary posts. Lima's economically active population totaled 1.53 million in 1981, 71% of whom were men. On average, each household has 1.8 income earners, and only 17% have more than 2. A 1978 survey revealed that the families of Lima spend an average of 45.2% of their incomes on food, 15.6% on housing and utilities, 9.8% on transport and communication, 7.4% on education, sports, and cultural activities, 7.3% on clothing, and 7.0% on furniture and housing maintenance.

  3. Incorporation of water-use summaries into the StreamStats web application for Maryland

    Approximately 25,000 new households and thousands of new jobs will be established in an area that extends from southwest to northeast of Baltimore, Maryland, as a result of the Federal Base Realignment and Closure (BRAC) process, with consequent new demands on the water resources of the area. The U.S. Geological Survey, in cooperation with the Maryland Department of the Environment, has extended the area of implementation and added functionality to an existing map-based Web application named StreamStats to provide an improved tool for planning and managing the water resources in the BRAC-affected areas. StreamStats previously was implemented for only a small area surrounding Baltimore, Maryland, and it was extended to cover all BRAC-affected areas. StreamStats could provide previously published streamflow statistics, such as the 1-percent probability flood and the 7-day, 10-year low flow, for U.S. Geological Survey data-collection stations and estimates of streamflow statistics for any user-selected point on a stream within the implemented area. The application was modified for this study to also provide summaries of water withdrawals and discharges upstream from any user-selected point on a stream. This new functionality was made possible by creating a Web service that accepts a drainage-basin delineation from StreamStats, overlays it on a spatial layer of water withdrawal and discharge points, extracts the water-use data for the identified points, and sends it back to StreamStats, where it is summarized for the user. The underlying water-use data were extracted from the U.S. Geological Survey's Site-Specific Water-Use Database System (SWUDS) and placed into a Microsoft Access database that was created for this study for easy linkage to the Web service and StreamStats. This linkage of StreamStats with water-use information from SWUDS should enable Maryland regulators and planners to make more informed decisions on the use of water resources in the BRAC area, and the technology should be transferrable to other geographic areas.

    Despite a substantial evidence base, implementation of pharmacogenetics into routine patient care has been slow due to a number of non-trivial practical barriers. We implemented a Personalized Anti-platelet Pharmacogenetics Program (PAP3) for cardiac catheterization patients at the University of Maryland Medical Center and the Baltimore Veterans Administration Medical Center Patients are offered CYP2C19 genetic testing, which is performed in our Clinical Laboratory Improvement Amendment (CLIA)-certified Translational Genomics Laboratory. Results are returned within five hours along with clinical decision support that includes interpretation of results and prescribing recommendations for anti-platelet therapy based on the Clinical Pharmacogenetics Implementation Consortium guidelines. Now with a working template for PAP3, implementation of other drug-gene pairs is in process. Lessons learned as described in this article may prove useful to other medical centers as they implement pharmacogenetics into patient care, a critical step in the pathway to personalized and genomic medicine.

    Chemically speciated PM2.5 and trace gases were measured at Fort Meade (FME: 39.10°N, 76.74°W; elevation 46 m MSL) during summer 2001 (6/30 through 8/3) as a continuous effort of the Maryland Aerosol Research and CHaracterization study. FME is suburban and within 30 km south of the urban Baltimore supersite. 24-hr PM2.5 mass ranged from 2.1 to 29.5 mg m-3. Major species, by average mass fraction, includes sulfate (37%), organic matter (27%), ammonium (13%), elemental carbon (6%), nitrate (3%), and crustal material (3%). Reconstructed PM2.5 mass, calculated by summing the major species, is generally less than the gravimetric mass but within 10% difference. Visible extinction coefficient (bext) was recorded by an Automated Surface Observing System at the Baltimore Washington International Airport and column aerosol optical depth (AOD) by sun radiometers at the Goddard Space Flight Center to evaluate the conditions of regional haze. Both detectors were located within 20 km from FME. The correlation (r2) between 24-hr bext and PM2.5 is low at 0.25 but increases to 0.51 when the aerosol water content, estimated using an aerosol thermodynamic modal ISORROPIA, is taken into account. Water contributed significantly on hazy days. This correlation suggests a mass extinction efficiency of ~ 9 m2 g-1. The hourly AOD at 500 nm was highly correlated with bext in the early morning and late afternoon (r2 ~ 0.9) but not during mid-day hours (r2 ~ 0.3) when bext is generally lower. This result, along with aircraft and ground lidar measurements, implies aloft fine aerosol mass in mid-day and a potentially stronger radiative forcing for the urban corridor.

    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. PMID:26753881

    The tragic April 19, 2015, death of an African American man injured while in police custody spurred several days of protest and civil unrest in Baltimore City. This article outlines the opportunity and role for a local health department during civil unrest, from the perspective of 2 emergency physicians who also led the Baltimore City Health Department through these recent events. Between April 27 and May 8, 2015, the Health Department was a lead agency in the unrest response and recovery activities. Similar to an emergency medical situation, a "public health code" is proposed as a model for centralizing, reacting to, and debriefing after situations of civil unrest.

    1980-01-01

    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.

    Anal sex is an efficient mode of STI transmission and studies indicate that anal sex is common among heterosexuals, including adolescents. We examined the association between individual, partner, and sexual partnership-level characteristics with anal sex among a household survey of 263 individuals aged 15-24 years in Baltimore City, Maryland. We used weighted multiple logistic regression to examine correlates of anal sex in a heterosexual partnership by gender. Twenty-nine percent of males and 15% of females reported anal sex in a partnership in the past 6 months. For males, anal sex was associated with having two or more partners in the past 3 months (AOR = 13.93, 95% CI 3.87-50.12), having been tested for HIV (AOR = 0.30, 95% CI 0.12-0.72), and oral sex with a partner (AOR = 8.79, 95% CI 1.94-39.78). For females, anal sex was associated with reporting having a main partner (AOR = 6.74, 95% CI 1.74-23.65), partner meeting place (AOR = 3.03, 95% CI 1.04-8.82), partner history of STI (AOR = 0.20, 95% CI 0.05-0.85), and oral sex with a partner (AOR = 8.47, 95% CI 1.08-66.25). Anal sex was associated with inconsistent condom use for both males (OR = 5.77, 95% CI 1.68-19.79) and females (OR = 5.16, 95% CI 1.46-18.30). We conclude that anal sex is a prevalent risk behavior among heterosexual youth and is associated with a range of factors at the individual and partnership levels. These findings provide support for comprehensive sex education that includes information about anal sex; findings from this study can inform public health campaigns targeting youth at risk for STIs.

  14. Baltimore and the Beginnings of the Fluoride Controversy.

    PubMed

    Daws, Steven

    2015-01-01

    The fluoridation of municipal water as a preventive dental health measure has proven to be a contentious issue from its very outset. In 1952, Baltimore became the first major city in the United States to artificially add fluoride to its water supply. This study draws largely on print media sources as a means of discerning public sentiment, in order to evaluate the nature of Baltimore's fluoride controversy in its infancy. Initial response was influenced by prior exposure to the substance within the context of dentistry, as well as a continued trend of conservatism within the community. Logistical issues during implementation due to the necessary upscale of established practices to accommodate Baltimore's population served to further exacerbate concerns. Much of the opposition was predicated on the breadth of the measure, as evidenced by the myriad of personal concerns put forth in objection. Personal concerns developed into demands for personal autonomy, providing a philosophical foundation for the anti-fluoridation movement that persists today. PMID:26930845

    Elevated levels of tropospheric ozone caused by its precursor emissions of NOx and VOCs have a negative impact on human health and crops. Informed regulatory decisions on how to reduce surface ozone in the Baltimore-Washington region can be made with a thorough understanding of urban plume chemistry and climate. The ozone production efficiency (OPE), which is based on the observed ratio of O3 and various nitrogen species, provides a mechanism for quantitatively assessing air quality representation of a key component of the photochemical evolution of urban plumes. We investigate the representation of ozone precursors within the CMAQ (Community Multi-scale Air Quality) air quality model, with a focus on assessing how well the model represents NOx and HOx chemistry. A comprehensive set of atmospheric observations for which OPE can be found and HO2 and RO2can be inferred, is available from NASA's DISCOVER-AQ campaign for July 2011 in the Baltimore-Washington region. Preliminary results show that the OPE as well as the NOx/NOy ratio in the Baltimore-Washington region derived from measurements is twice as high as within CMAQ, and that isoprene and formaldehyde are too low within CMAQ. Implications for policy will be briefly discussed.

    Cunningham, Shayna D.; Kerrigan, Deanna L.; McNeely, Clea A.; Ellen, Jonathan M.

    2016-01-01

    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. Church leaders varied, however, in the extent to which they responded in accordance with or resisted these constraints, highlighting the importance of individual agency influencing churches’ responses to HIV/AIDS.

  17. Environmental Inequality in Metropolitan America

    2009-01-01

    This study compares the environmental hazard burden experienced by Blacks, Hispanics, Pacific Islanders, Native Americans, Asian Americans, and Whites in each of the 329 metropolitan areas in the continental United States, using toxicity-weighted air pollutant concentration data drawn from the Environmental Protection Agency's Risk-Screening Environmental Indicators project to determine whether and to what degree environmental inequality exists in each of these metropolitan areas. After demonstrating that environmental inequality outcomes vary widely across metropolitan areas and that each group in the analysis experiences a high pollution disadvantage in multiple metropolitan areas and a medium pollution disadvantage in many metropolitan areas, the authors test three hypotheses that make predictions about the role that residential segregation and racial income inequality play in producing environmental inequality. Using logistic regression models to test these hypotheses, the authors find that residential segregation and racial income inequality are relatively poor predictors of environmental inequality outcomes, that residential segregation can increase and decrease racial/ethnic group proximity to environmental hazards, and that the roles income inequality and residential segregation play in producing environmental inequality vary from one racial/ethnic group to another.

    Severtson, Stevan Geoffrey; Latimer, William W.

    2009-01-01

    Aim We investigated the moderating effect of impulse control on the association between drug use and incarceration among active injection drug users (IDU). Methods The study sample consisted of 282 IDUs aged 15 to 50 years from the Baltimore metropolitan region who reported injection drug use within the past 6 months and indicated that heroin or speedball was their drug of choice. Impulse control was measured using commission error standardized scores from the Test of Variables of Attention (TOVA). Incarceration was obtained using self-reported lifetime history of incarceration in correctional facilities. Results Findings indicated that impulse control moderated the association between years of injection drug use and incarceration in correctional facilities adjusting for ethnicity, gender, estimated pre-morbid intelligence, and age of first injection use. Specifically, among individuals that were intact in impulse control, four or more years of injection drug use was associated with incarceration (AOR=4.97, 95% CI: 2.02–12.23). This finding was not observed among individuals with impaired impulse control (AOR=0.57, 95% CI: 0.10–3.23). Furthermore, impulse control moderated the association between regular cocaine use and incarceration. Among individuals that had a history of cocaine use, individuals with low impulse control but not impaired were more likely to have reported time in a correctional facility (AOR=6.28, 95% CI: 1.68–23.60). There was no association among individuals with impaired or intact impulse control. Conclusion Results highlight the importance of considering cognitive measures of impulse control in addressing negative outcomes associated with drug use. PMID:18082337

  3. The clinic and elsewhere: illness, sexuality, and social experience among young African American men in Baltimore, Maryland.

    PubMed

    Meyers, Todd; Leonard, Lori; Ellen, Jonathan M

    2004-03-01

    This paper is concerned with how disclosure becomes self-production for young adults within the setting of the sexually transmitted disease (STD) clinic. The STD clinic is a special medical environment where the process of disclosure is not just a way of accessing treatment; it is also a process through which illness, sexuality, and social experience become entangled in telling. Illness according to medical categories is reshaped in the social world, bringing a different set of criteria to bear on the definition of illness. The concern we raise regards how meaning is secured simultaneously through the experience of illness and social relations. Using data from a series of clinic-based ethnographic interviews, we examine the narratives of three young men. Together, the narratives demonstrate the interrelatedness of illness and self-production in various forms. In one case the tension between interpersonal violence and self-preservation is central. In another, the place of knowledge in family relationships renders the entire picture of the social unstable. The paper signals a number of issues absent in clinical and epidemiological depictions of vulnerability, particularly in the context of the urban United States. PMID:15074551

    The authors have identified the following significant results. Field work in Baltimore County revealed that the signature returns of serpentinitic and nonserpentinitic rocks correlates with the vegetation cover and land use pattern. In Maryland Piedmont, bedrock lithology and structure are enhanced only to the extent that land use is geologically dictated. Two prominent sets of linear features are detected on ERTS-1 imagery at N 45 deg E and N 20 deg E. Beaches of Chesapeake Bay are classified as broad and narrow beaches based on the width of the backshore zone. It is shown by comparing historical shorelines of Ocean City, from the inlet to the Maryland-Delaware line that reversal zones of erosion and accretion occur at different locations for different periods. High reflectance levels (high marsh-high topographic areas) for the lower Eastern Shore are found to be distributed as two distinct trending linear ridge systems. Observations of MSS band 5 dated 9 April 1974 exhibited an unique sedimentation pattern for Chesapeake Bay. Following a 1.5 inch rainfall, heavy concentration of suspended sediments is observed on the imagery, particularly in the area of the turbidity maximum.

    Williams, Ron; Creason, John; Zweidinger, Roy; Watts, Randall; Sheldon, Linda; Shy, Carl

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

  4. Baltimore Canyon Trough, a clastic-carbonate system

    SciTech Connect

    Edson, G.M. )

    1990-05-01

    Baltimore Canyon Trough is similar in age, architecture, and sedimentary framework to neighboring marginal basins offshore from eastern North America. The other basins are the Scotian and Georges Bank basins and the Carolina Trough. All contain a Jurassic-earliest Cretaceous clastic-carbonate sedimentary section composed of terrigenous basin fill and a shallow-water limestone platform. In Baltimore Canyon Trough, the platform is believed to be over 10 km thick. Upward through the Jurassic System, the platform progrades seaward and narrows. The platform top is earliest Cretaceous (Berriasian) and only about 5-15 km wide. Width of the base is indeterminate but apparently much wider. At the seaward edge of the platform is a limestone buildup and reef complex that consists of bioclastic wackestones, packstones, grainstones, and sponge-stromatoporoid-algal bindstones. Foreslope deposits are thrombolitic stromatactis-pelletal carbonate mudstones. Landward of the buildup, the platform contains numerous siliciclastic interbeds, consisting of mostly calcareous shale and siltstone with inertinite. The calciclastic lime mudstone beds of the platform contain terrigenous siliciclasts and kerogens. All units are oxidized and show considerable sedimentary reworking. Through the Jurassic System and into the Cretaceous, terrigenous clastic sediments became increasingly dominant in the basin and erosional-depositional cycles continually reworked carbonate, as well as siliciclastic, units.

  5. The Baltimore and Utrecht models for cluster dissolution

    NASA Astrophysics Data System (ADS)

    Lamers, Henny J. G. L. M.

    2009-12-01

    The analysis of the age distributions of star cluster samples of different galaxies has resulted in two very different empirical models for the dissolution of star clusters: the Baltimore model and the Utrecht model. I describe these two models and their differences. The Baltimore model implies that the dissolution of star clusters is mass independent and that about 90% of the clusters are destroyed each age dex, up to an age of about a Gyr, after which point mass-dependent dissolution from two-body relaxation becomes the dominant mechanism. In the Utrecht model, cluster dissolution occurs in three stages: (i) mass-independent infant mortality due to the expulsion of gas up to about 107 yr; (ii) a phase of slow dynamical evolution with strong evolutionary fading of the clusters lasting up to about a Gyr; and (iii) a phase dominated by mass-dependent dissolution, as predicted by dynamical models. I describe the cluster age distributions for mass-limited and magnitude-limited cluster samples for both models. I refrain from judging the correctness of these models.

    Almost 100 years ago, the study of Maryland Mammoth tobacco by Garner and Allard was one in a long series of studies that have led to a better understanding of how plants "decide" when to flower. deciphering how plants "decide" when to flower. The extreme phenotype of Maryland Mammoth tobacco, in which a single recessive mutation changes a day-neutral to a strictly photoperiod-requiring plant, impressively illustrates the action of the photoperiodic pathway of flowering.

    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.

  13. Sedimentological indicators of paleoenvironments and siliciclastic stratigraphic sequences in some Miocene deposits of the Calvert Cliffs, southern Maryland

    USGS Publications Warehouse

    Shideler, G.L.

    1994-01-01

    Middle Miocene siliciclastic deposits comprising the Calvert Cliffs section at the Baltimore Gas and Electric Company's (BG&E) nuclear power plant site in southern Maryland were analyzed in terms of lithostratigraphy, sedimentary structures, and granulometric parameters, to interprete paleo-environments within a sequence-stratigraphic framework. In terms of sequence-stratigraphic models, the BG&E section can be interpreted as consisting of two genetic stratigraphic sequences (Galloway model), namely, a shelf sequence and an overlying deltaic sequence. Using the Exxon model, the section consists of two third-order (1-5 m.y. duration) depositional sequences. The stratigraphic sequences of the BG&E section reflect both relatively short-term eustatic transgressive events, as well as a long-term regressive trend with associated local deltation and coastal progradation. The regression probably signified a regional basinward shift of depocenters within the Salisbury embayment during Miocene time. -from Author

  14. Project-based Modules from two STEM Learning Teams in Howard County, Maryland

    NASA Astrophysics Data System (ADS)

    Griffiths, L. N.; Bradley, L. A.

    2011-12-01

    In 2009, two Maryland school districts-Howard County Public School System and Prince George's County Public Schools-and the Goddard Space Flight Center of the National Aeronautics and Space Administration (NASA) partnered with the National Commission on Teaching and America's Future (NCTAF) to develop NASA 21st Century Learning Studios. In 2010, NCTAF expanded the program to include Learning Studios at two additional Maryland school districts (Anne Arundel County Public Schools and Baltimore County Public Schools), partnering with the United States Naval Academy and the University of Maryland. Overall, the focus of these Learning Studios is to combine the expertise of scientists with that of educators through Learning Teams to improve teaching and learning in science, technology, engineering and mathematics (STEM) fields, while delivering project-based modules to be implemented in other school districts. The focus of this paper is to summarize the experience and outcomes from two Learning Teams from the Howard County Public School System. STEM Learning Teams were established at Centennial High School and Hammond High School in Maryland. Each Team worked together for two years to create interdisciplinary units of study for their students with a focus on Earth Science. To maximize student interest, teachers worked with NASA scientists five times a year to develop four learning modules using practical examples and incorporating real scientific observations. A weathering and erosion module challenges students to collect appropriate field observations and determine erosion and deposition rates in a nearby lake. A plate tectonics module requires students to use measures of plate motion from the National Oceanic and Atmospheric Administration to estimate rates of convergence in southern Asia. A third module for lessons in climate change requires students to find open source climate data, determine changes in the atmosphere and estimate anthropogenic impacts. A follow-up exercise challenges students to find ways to alter their schools, homes and individual activities for reducing carbon footprints. A fourth module requires students to model solar and lunar eclipses in different ways, and to combine this understanding with the personal experiences of a NASA scientist. The intended outcomes from an implementation of these four modules are: to present real-world practical problems to be solved by the students; to expose students to areas of active research; and to expose students to careers in STEM. Such experience should improve their preparations for new opportunities after high school.

  15. Characterization of nested watershed hydrologic response from high-resolution rainfall and runoff data in the Baltimore Ecosystem Study LTER

    2011-12-01

    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 rise and peak at the same time as their tributaries, and in other cases the larger watersheds exhibit a double peak in response to a single rainfall pulse, with the first peak (thought to be derived from local storm drains) occurring before peaks recorded upstream in tributary watersheds. Although there are pronounced differences in patterns of development and extent of stormwater management between the different tributary watersheds, observed hydrologic response does not always conform to the expected effects of these patterns. Hydrograph behavior with the change in scale from 5-6 km2 to 14 km2 is more predictable as a combination of translation and attenuation of the tributary hydrographs.

  16. Impacts of Title IV in Maryland

    1995-12-31

    The Maryland Department of Natural Resources` Power Plant Research Program has evaluated the environmental effects of acid deposition on Maryland`s air, land, water (especially the Chesapeake Bay), and human resources since the mid-1980`s. Title IV of the Clean Air Act Amendments of 1990 (CAAA90) has focused much attention on the mandated reductions of nitrogen oxides (NO{sub x}) and sulfur dioxide (SO{sub 2}) to control acid deposition. Baseline data on acidic deposition and air emissions/pollution control for NO{sub x} and SO{sub 2} acquired through PPRP studies have proved useful in evaluating the impacts of Title IV on Maryland power plants and resources. Three example programs are discussed: The first is an evaluation of SO{sub 2} emissions on ecosystems through the use of critical loads--the amount of acid rain that an ecosystem can tolerate without continuing to acidify. Results support the use of broadly based emissions trading scenarios: The second study is an evaluation of the potential for reducing nitrate loading in the Chesapeake Bay by reducing NO{sub x} emissions. Results indicate substantial NO{sub x} emission reductions could offer significant reductions in nitrate deposition to the Bay: The final study is a review of the impacts of Title IV on the Maryland coal industry and the prospects for coal cleaning and advanced combustion technologies. Current results indicate that Maryland coal will meet Phase 2 SO{sub 2} emission standards using advanced combustion techniques, such as fluidized bed technologies, but that additional emissions controls, such as a scrubber would be required in a conventional boiler.

    An experimental portable lightning mapping array (LMA) operating in the upper VHF TV band (Channels 7-13; 174-216 MHz) was deployed in the Washington DC Metropolitan area during the summer 2006 to locate and monitor the overall lightning activity. The LMA network provides total lightning data to support lightning research as well as proxy data to benefit the development of applications for planned observing systems such as the GOES-R Geostationary Lightning Mapper. The portable LMA hardware is a compactly-housed, easily deployed version of the LMA stations installed North Alabama, Oklahoma, and New Mexico, which operate in the lower VHF TV band (Channels 2-6,54-88 MHz). Real-time LMA data products are provided to the National Weather Service Weather Forecast Office (WFO) in Sterling, VA to aid in their forecast and warning operations. Forecasters at WFO Sterling have already found the lightning data from the Washington DC demonstration network to be very useful in assessing the development of storm systems. On July 4,2006, data from the LMA aided forecasters as they monitored an area of convection that later developed into a line of severe storms that moved southward through the Washington DC metropolitan area across the Washington Mall. Additional applications of lightning mapping data in the Baltimore-Washington DC urban environment will be discussed.

    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.

A total of 325 PM2.5 personal exposure samples were obtained during a 28-day study period using a subject pool of 21 elderly (65+ years of age) residents of an 18-story retirement facility near Baltimore, Maryland. Each sample represented a unique 24-h breathing zone measurement of PM2.5 mass concentration. PM2.5 and PM10 mass concentrations collected from the apartments of the subjects as well as residential and ambient sites were compared to individual and mean PM2.5 personal exposures. Daily PM2.5 personal exposure concentrations ranged from 2.4 to 47.8 microg/m3 with an overall individual study mean of 12.9 microg/m3. Mean PM2.5 personal exposures were determined to be highly correlated to those representing the central indoor (r=0.90) and ambient sites (r=0.89). Subjects reported spending an average of 92% of each day within the confines of the retirement center. Based upon measured and modeled exposures, a mean PM2.5 personal cloud of 3.1 microg/m3 was estimated. Data collected from these participants may be unique with respect to the general elderly population due to the communal lifestyle within the facility and reported low frequency of exposure to sources of PM.

    The land-use and land cover (LULC) history of the Baltimore-Washington region has been intensively studied through a variety of environmental research collaborations and regional partnerships. One such partnership, the Baltimore-Washington Regional Collaboratory, involved multiple Federal and local agencies cooperating on a 200-year urban growth study in the Chesapeake region. Information from this study on pre-1900 and current LULC conditions for the Baltimore-Washington DC area was integrated with data from other sources to construct different lower boundary conditions for a series of simulations using the Colorado State University (CSU) Regional Atmospheric Modeling System (RAMS). We use the RAMS simulations to diagnose the extent and nature of the effect of urban anomalies in surface heat, moisture, and momentum on mid-summer local and regional climate. The experimental design adopted for this study takes advantage of the grid-nesting capability of RAMS. A fine grid with 1km horizontal resolution was nested into a coarser 5 km grid, which extends from southern Pennsylvania, Maryland, to parts of Virginia, and West Virginia. Two sets of month-long simulations for July 2000 were conducted with RAMS running in parallel on a 26-processor cluster of computers at the Cooperative Institute for Research in the Atmosphere (CIRA), CSU. In the first set of simulations, we initially used satellite-derived current land cover data as the lower boundary condition in a 31-day RAMS run. We then replaced this data with the pre-1900 land cover data for the same region and ran a similar RAMS simulation. Identical observed meteorology was retained for the lateral boundary conditions in both cases. The model results for the initial run were validated with July 2000 surface climate data and flux measurements of sensible and latent heat from sites located within the fine grid model domain. Additional simulations were conducted to compare RAMS model performance using prescribed land surface conditions with results from a physically based scheme for urban energy budget coupled to RAMS. The urban surface scheme used here is the Town Energy Budget (TEB) model recently developed at the Center for Meteorological Research (CNRM), France. The TEB model allows for a refinement of model computed radiative budgets, heat and momentum based on a generalization of the classic canyon approach. Results from both sets of simulations, and the implications, for surface climate, of the driving human-induced land cover transformations are discussed.

    2011-01-01

    Major sources of flavonoids were identified, and mean intakes over several decades were reported, among 1638 participants (mean age 62.1 +/− 16.0 y), of the Baltimore Longitudinal Study of Aging (BLSA). Dietary data were collected using 7-day diet records during three time periods (1980s, 1990s and 2000-present), and the USDA flavonoid, proanthocyanidin and isoflavone databases were used to estimate dietary flavonoid intakes. Dietary intake data were divided according to decade of visit. Foods were matched with appropriate foods in the USDA databases. Mixed dishes were disaggregated to individual foods and a similar procedure was followed. Total flavonoids and five sub-classes of flavonoids, including flavonols, flavones, flavanones, flavan-3-ols and anthocyanidins, were computed by summing appropriate compounds. The median intakes of flavonoids and the contributions of various foods to intakes were calculated by decade. Age and sex adjusted mean (SE) daily intakes of flavonoids increased from 250 (7.4) in the 1980s to 280 (9.9) mg in the 2000s. Top contributors of flavonoids were tea, apple/pear (and juices), citrus fruits (and juices), peaches, plums, grapes, nectarines (and juices) and chocolate. The data show an increase in the consumption of flavonoids over the three decades, which appears to be related to intake of fruit. PMID:22228923

    2009-01-01

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

    2009-09-01

    Recent extreme hydroclimatic events in the United States alone include, but are not limited to, the droughts in Maryland and the Chesapeake Bay area in 2001 through September 2002; Lake Mead in Las Vegas in 2000 through 2004; the Peace River and Lake Okeechobee in South Florida in 2006; and Lake Lanier in Atlanta, Georgia in 2007 that affected the water resources distribution in three states - Alabama, Florida and Georgia. This paper provides evidence from previous work and elaborates on the future perspectives that will collectively employ remote sensing and in-situ observations to support the implementation of the water availability assessment in a metropolitan region. Within the hydrological cycle, precipitation, soil moisture, and evapotranspiration can be monitored by using WSR-88D/NEXRAD data, RADARSAT-1 images, and GEOS images collectively to address the spatiotemporal variations of quantitative availability of waters whereas the MODIS images may be used to track down the qualitative availability of waters in terms of turbidity, Chlorophyll-a and other constitutes of concern. Tampa Bay in Florida was selected as a study site in this analysis, where the water supply infrastructure covers groundwater, desalination plant, and surface water at the same time. Research findings show that through the proper fusion of multi-source and multi-scale remote sensing data for water availability assessment in metropolitan region, a new insight of water infrastructure assessment can be gained to support sustainable planning region wide.

    Gamma-ray and neutron background surveys were performed by the Naval Research Laboratory (NRL) in U.S. cities, including Washington, D.C.; Kansas City and St. Louis, Missouri; Chicago, Illinois; Richmond, Virginia; Boston, Massachusetts and Baltimore, Maryland. Measurements covered a range of industrial, residential and commercial areas. Germanium grade gamma-ray data over the energy range of 0.05-3.0 MeV and neutron count rates with unmoderated He-3 sensitivity were recorded as a function of latitude, longitude and elevation in one second intervals. Typical Potassium Uranium Thorium (KUT) backgrounds were seen along with several anomalies. For example, a decrease in the thermal neutron flux in large urban canyons was seen and verified via Monte Carlo simulations. The data were collected to provide natural background models for simulation work. Germanium grade spectroscopy is required, because it provides sufficiently detailed isotopic information of the gamma-ray background. As expected a comparison of the background shows significant differences between the individual cities.

    In July and August 1999 a Northeast Oxidant and Particle Study field campaign was conducted in the Philadelphia metropolitan area to determine causes for episodically high levels of O{sub 3} and particulate matter {<=}2.5 {micro}m in aerodynamic diameter. We report emission estimates, weather information, surface O{sub 3} monitoring data, and aircraft observations, with a focus on 31 July, the last day of an O{sub 3} episode in which concentrations in Philadelphia reached 165 ppb, the highest level observed there in the past 11 years. As is common in the northeastern states, this O{sub 3} episode started with the development of a broad ridge over the central United States and ended with the northeast corridor under the influence of an Appalachian lee trough with airflow from the SW in an along-corridor direction. For a portion of the morning of 31 July, winds were nearly stagnant, allowing local emissions to accumulate. In contrast to typical O{sub 3} episodes in the northeast, transport on 31 July was limited, and O{sub 3} hot spots occurred close to NO{sub x} and volatile organic compound (VOC) emission sources. High O{sub 3} was observed downwind of Baltimore and Philadelphia, both major urban areas. High O{sub 3} was also observed in a less likely region near the Delaware-Pennsylvania border, downwind of Wilmington, Delaware, but near utility and industrial emission sources. Surface O{sub 3} monitoring data and morning aircraft observations show that the residual layer aloft contained 80-100 ppb of O{sub 3} but almost no O{sub 3} precursors. Same-day photochemistry on 31 July caused surface O{sub 3} concentrations to increase by 60-80 ppb. Photochemical model calculations indicate O{sub 3} production rates in excess of 20 ppb h{sup -1} in regions with NO{sub x} > 5 ppb. High NO{sub x} concentrations are a consequence of poor ventilation. Peroxide observations and calculations indicate that O{sub 3} production is VOC limited in the high-NO{sub x} portions of the Philadelphia urban plume. Our results are contrasted against a severe O{sub 3} episode that occurred in 1995. While the 1999 episode had stagnation conditions leading to local O{sub 3} hot spots, there were mesoscale meteorological features in 1995 that favored interregional transport.

  12. Metal concentrations in Maryland`s shellfish: 1970s--1990s

    SciTech Connect

    Murphy, D.L.

    1995-12-31

    Maryland has been monitoring arsenic, cadmium, chromium, copper, lead, mercury and zinc in bivalve shellfish from state waters since the 1960s. The primary bivalve species monitored in Maryland waters are the oyster, Crassostrea virginica and the softshell clam, Mya arenaria. These data have been evaluated for temporal trends. In order to insure that temporal evaluations be based upon data produced using comparable analytical methods, the time period evaluated is not the same for all analytes. For example, while most evaluations are for the period 1974 through 1994, arsenic data were evaluated for the period 1980 through 1994. Data for oyster tissue indicate declines in levels of mercury, cadmium, arsenic, copper and zinc on the order of 70--90%. The major portion of these reductions occurred prior to 1985. These declines are evident from data collected from Maryland`s lower eastern shore, a relatively remote area, as well as from waters closer to larger population centers. Past detection levels for lead and chromium were insufficiently low to detect temporal changes.

  16. A comparison of metropolitan and non-metropolitan employment characteristics: Indications of the size of non-metropolitan mobile communication services user classes

    NASA Technical Reports Server (NTRS)

    Wilcox, R. E.

    1985-01-01

    The similarities and differences between areas inside and outside U.S. metropolitan areas were evaluated in terms of their commercial/industrial and government employment characteristics. The comparison focuses on the levels, shares, and composition of employment in the commercial/industrial and government sectors that represent potential classes of land mobile communications users. The major findings of the analysis are as follows: (1) non-metropolitan commercial/industrial user classes of land mobile communication services exist in significant numbers; (2) the compositions of non-metropolitan and metropolitan commercial/industrial user classes of land mobile communication services closely resemble each other; (3) non-metropolitan areas have significant levels of the government user classes that represent potential markets for land mobile communication services; and (4) non-metropolitan local governments have a significantly larger proportion of their employment in the primary user classes of private land mobile radio service than do metropolitan local governments.

  17. Baltimore WATERS Test Bed -- Quantifying Groundwater in Urban Areas

    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-scale microgravity survey was conducted over this area and will be repeated in spring. Efforts to quantify other components of the water cycle include: (1) deployment of an eddy covariance station for ET measurement; (2) mining flow metering records; (3) evaluation of long-term stream-flow data records; and (4) processing precipitation fields. The objective of the precipitation analysis is to obtain rainfall fields at a spatial scale of 1 sq km for the study area. Analyses are based on rain gage observations and radar reflectivity observations from the Sterling, Virginia WSR-88D radar. Radar rainfall analyses utilize the HydroNEXRAD system. Data is being managed using the CUAHSI HIS Observations Data Model housed on a HIS server. The dataset will be made accessible through web services and the Data Access System for Hydrology.

    Connor, Katherine A; Cheng, Diana; Strobino, Donna; Minkovitz, Cynthia S

    2014-12-01

    Despite current guidelines that all reproductive age women receive preconception care (PCC), most US women do not, especially women with a prior birth. The objective of our study was to identify factors associated with receipt of PCC health promotion counseling among Maryland women and to assess whether prior birth outcome affects receipt of counseling. We analyzed Maryland pregnancy risk assessment monitoring system data for a stratified random sample of women with a live birth in 2009-2010; 3,043 women with PCC data were included in the analysis. The dependent variable was receipt of any PCC counseling, and the primary independent variable, prior pregnancy outcome (no prior live birth, term, preterm). 33.1 % of the weighted sample received PCC. Odds of PCC were similar for women with a history of prior prior preterm birth (aOR 1.00, 95 % CI 0.57-1.78) and no prior live birth, but decreased for women with a prior full term delivery (aOR 0.69, 95 % CI 0.51-0.94). They were decreased for women with unintended births (aOR 0.36, 95 % CI 0.26-0.51) and increased for women with a diagnosis of asthma (aOR 1.74, 95 % CI 1.05-2.89) or diabetes (aOR 2.79, 95 % CI 1.20-6.45), who used multivitamins (aOR 2.58, 95 % CI 1.92-3.47), and had dental cleanings (aOR 1.60, 95 % CI 1.16-2.18). Although selected preventive health behaviors and high-risk conditions were associated with PCC, most women did not receive PCC. Characterization of women who do not receive PCC health promotion counseling in Maryland may assist in efforts to enhance service delivery. PMID:24748212

    During 1954-1960, 2005 mammals of 18 species collected at the Patuxent Wildlife Research Center, Maryland, were examined for trypanosomes. T. cruzi was found in 10 raccoons between October 31 and November 30. Infection occurred in 2 percent of all raccoons sampled, and in 11.3 percent of the 80 raccoons sampled in November. Examination was by direct smears, stained smears and cultures of heart blood. Although, in previous studies, at least two experimentally infected raccoons exhibited extended parasitemia (14 and 8 weeks), no such continuing parasitemia was observed in the natural infections. No trypanosomes were found in any of the other mammals examined.

  5. Maryland striped bass: recruitment declining below replacement

    1985-01-01

    A mathematical technique was developed to examined interrelationships among first-year survival rates, adult fecundity, and adult survival of striped bass Morone saxatilis based on indices of year-class strength. Application of this technique to striped bass in Maryland waters of the Chesapeake Bay provided evidence for reduced survival in the life cycle. If adult fecundity and survival have remained constant, first-year survival declined significantly from 1969 to 1983, and averaged less than that needed for replacement for the last 10 years. Treatment of the individual spawning grounds separately indicated that the downward trend in survival for the pooled data was the result of declines in the upper bay and, to a lesser extent, in the Choptank River. Alternatively, if first-year survival and adult fecundity were assumed to have remained constant, an annual decline of about 1.9% in adult survival would have been required to produce the observed trend in the pooled year-class data. This would be consistent with increased fishing mortality and implies declining recruitment because of declining stock size. Continuing declines in first-year or adult survival would eliminate the Maryland striped bass stock and the fishery it supports. Conversely, an increase in adult survival could offset of the unknown factor or factors responsible for the apparent decline in first-year survival. 25 references, 1 figure, 1 table.

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

    NASA Astrophysics Data System (ADS)

    Obasanjo, Olugbenga Olufemi

    Given the reemergence of Tuberculosis (TB) in the United States (U.S.) in the 1980s and 1990s, several strategies have emerged to combat the disease. A successful tool has been Directly Observed Therapy (DOT). Chaulk, et al. showed that DOT was responsible for the maintaining the decline in TB rates in Baltimore through the corresponding period of an upswing in rates nationally. In this study, we measure the impact of DOT on the geographic pattern of TB in Baltimore. We used Geographical Information System (GIS) methods to compare the geographic patterns of TB in Baltimore before and after the introduction of DOT in the city. We identified both predictors of TB, and differences in geographic units in Baltimore over time. We measured the impact of the introduction of DOT and Rifampin on various treatment outcomes for TB at about the same time. Despite the drop in numbers of TB cases, the spatial distribution of cases generally remained unchanged until 1995. This was confirmed by the fact that similar predictors were identified in all of the years that were analyzed. However, higher proportions of TB cases were found among blacks and females in more recent years. Death rates have increased significantly while corresponding relapse rates and the mean length of therapy have declined significantly. Rifampin was associated with a longer length of therapy before DOT, but with a shorter duration of therapy following the introduction of DOT. In all of the years analyzed, losses to follow-up (LTFU) do not differ from those completing therapy and are not spatially clustered relative to those completing therapy. DOT has been effective in reducing the numbers of TB cases in Baltimore city-wide without an emphasis on so-called "high-risk" patients for LTFU. Thus, any declines in TB case rates are not due to a decline in a particular group or geographic sector of the city. Universal DOT is effective and does not cause a geographic clustering of difficult-to-reach patients. This study effectively quantifies the effect of DOT in ensuring treatment completion for TB. This study also identifies changing patterns of TB disease in the city. These changing patterns, along with a leveling-off in the reduction of the annual incidence of TB in Baltimore, imply that newer approaches to controlling TB in the city need to be developed. Improving case findings through contact tracing and the use of Deoxyribonucleic Acid (DNA) fingerprinting are two strategies that have been added to strengthen and improve the TB control program. This study will provide a mechanism by which to measure the success of these new programs.

    1980-01-01

    Ozone and total oxidant concentrations in a rural atmosphere in Western Maryland were measured for the 2-week period 26 August to 9 September, 1980. Unusually high values for ozone, measured by a chemiluminescence method, and for total oxidant, measured by a colorimetric technique, were observed during both daylight and darkness. The 14-day average diurnal curve showed a minimum of 0.04 ppM ozone at 0845 EST, and a broad maximum of 0.075 ppM ozone at 1300 to 1830 EST. A maximum 15-minute average concentration of 0.13 ppM was measured. The average ozone concentration for the entire 14-day period was 0.059 ppM, while the total oxidant concentration was 0.060 ppM.

    The average number of hawks observed per hour in autumn migration between 1951-1954 and 1958-1961 at White Marsh, Maryland, was compared. The counts indicated that the status of the ten species observed may be divided into three categories: (1) relatively stable species (red-tailed hawk), (2) declining species (sparrow hawk, red-shouldered hawk, osprey, marsh hawk, and broad-winged hawk), and (3) rapidly declining species (peregrine falcon, Cooper?s hawk, bald eagle, and sharp-shinned hawk). The findings from this study are in agreement with the available literature and the status of the populations appears to be related to the food habits of the species.

    1988-01-01

    The Department of Meteorology at the University of Maryland is developing one of the first computer systems in meteorology to take advantage of the new networked computer architecture that has been made possible by recent advances in computer and communication technology. Elements of the department's system include scientific workstations, local mainframe computers, remote mainframe computers, local-area networks,'long-haul' computer-to-computer communications, and 'receive-only' communications. Some background is provided, together with highlights of some lessons that were learned in carrying out the design. In agreement with work in the Unidata Project, this work shows that the networked computer architecture discussed here presents a new style of resources for solving problems that arise in meteorological research and education.

    With its 3,100 miles of tidal shoreline and low-lying rural and urban lands, “The Free State” is one of the most vulnerable to sea-level rise. Historically, Marylanders have long had to contend with rising water levels along its Chesapeake Bay and Atlantic Ocean and coastal bay shores. Shorelines eroded and low-relief lands and islands, some previously inhabited, were inundated. Prior to the 20th century, this was largely due to the slow sinking of the land since Earth’s crust is still adjusting to the melting of large masses of ice following the last glacial period. Over the 20th century, however, the rate of rise of the average level of tidal waters with respect to land, or relative sea-level rise, has increased, at least partially as a result of global warming. Moreover, the scientific evidence is compelling that Earth’s climate will continue to warm and its oceans will rise even more rapidly. Recognizing the scientific consensus around global climate change, the contribution of human activities to it, and the vulnerability of Maryland’s people, property, public investments, and natural resources, Governor Martin O’Malley established the Maryland Commission on Climate Change on April 20, 2007. The Commission produced a Plan of Action that included a comprehensive climate change impact assessment, a greenhouse gas reduction strategy, and strategies for reducing Maryland’s vulnerability to climate change. The Plan has led to landmark legislation to reduce the state’s greenhouse gas emissions and a variety of state policies designed to reduce energy consumption and promote adaptation to climate change.

  12. A Tale of Two City Blocks: Differences in Immature and Adult Mosquito Abundances between Socioeconomically Different Urban Blocks in Baltimore (Maryland, USA)

    2014-01-01

    Infrastructure degradation in many post-industrial cities has increased the availability of potential mosquito habitats, including container habitats that support infestations of invasive disease-vectors. This study is unique in examining both immature and adult mosquito abundance across the fine-scale variability in socio-economic condition that occurs block-to-block in many cities. We hypothesized that abundant garbage associated with infrastructure degradation would support greater mosquito production but instead, found more mosquito larvae and host-seeking adults (86%) in parcels across the higher socio-economic, low-decay block. Aedes albopictus and Culex pipiens were 5.61 (p < 0.001) and 4.60 (p = 0.001) times more abundant, respectively. Most discarded (garbage) containers were dry during peak mosquito production, which occurred during the 5th hottest July on record. Containers associated with human residence were more likely to hold water and contain immature mosquitoes. We propose that mosquito production switches from rain-fed unmanaged containers early in the season to container habitats that are purposefully shaded or watered by mid-season. This study suggests that residents living in higher socioeconomic areas with low urban decay may be at greater risk of mosquito-borne disease during peak mosquito production when local container habitats are effectively decoupled from environmental constraints.

    1995-05-01

    To determine the incidence of and risk factors for human T-lymphotropic virus, type II (HTLV-II) seroconversion among injecting drug users (IDUs), specimens from IDUs recruited into the ALIVE Study in 1988/1989 were assayed at baseline for antibody to HTLV with use of enzyme immunoassay and Western blot. Participants were monitored semiannually with venipuncture and interviews. In 1992, the most recent sera of HTLV-negative participants were tested for HTLV with use of enzyme immunoassay and confirmed and typed by Western blot. For positive cases, assays were then performed for all intervening visits to determine the calendar time of seroconversion. Incidence rates were estimated using person-time. Risk factor analysis used a nested case-control design, with up to seven controls per case matched by time of study entry and duration of follow-up. At baseline, 251 HTLV-positive, 22 indeterminate, and 2,574 HTLV-seronegative IDUs were identified. Follow-up of the seronegative IDUs identified 38 seroconverters (all HTLV-II) over 5,813.6 person-years, for a rate of 0.7/100 person-years. Median lag time for seroconversion was 6.8 months. Factors associated with HTLV-II seroconversion included a specific needle-sharing practice called "backloading" within the previous 6 months [odds ratio (OR) = 6.52; 95% confidence interval (CI) = 1.94-21.95] and a baseline history of receiving money for sex (OR = 3.36; 95% CI = 1.32-8.57). Of those with more than one sex partner in the past 6 months, women were more likely than men to seroconvert (OR = 5.77; 95% CI = 1.33-25.05).(ABSTRACT TRUNCATED AT 250 WORDS) PMID:7712239

    This qualitative study utilized a time-geography framework to explore the daily routines and daily paths of African American men who have sex with men (AA MSM) and how these shape HIV risk. Twenty AA MSM aged 18 years and older completed an in-depth interview. Findings revealed (1) paths and routines were differentiated by indicators of socio-economic status, namely employment and addiction, and (2) risk was situated within social and spatial processes that included dimensions of MSM disclosure and substance use. This study highlights the critical need for future research and interventions that incorporate the social and spatial dimensions of behavior to advance our ability to explain racial disparities in HIV and develop effective public health responses.

    Unity in Diversity was a randomized controlled trial of a culturally tailored HIV prevention intervention for African American men who have sex with men (AA MSM). The intervention condition was six group-based sessions and one individual session. The control condition was a single-session HIV prevention review. Participants were aged 18 years or older, identified as African American/black race, reported having at least two sex partners in the prior 90 days (at least one of whom must be a male partner), unprotected anal sex with male partner in the prior 90 days and willing to test for HIV. Retention exceeded 95% at 3 month follow-up. Results of multivariate logistic regression analysis adjusting for baseline risk, HIV status and health insurance indicate intervention efficacy in decreasing the number of male sex partners and marginal effects on condom use with male partners and HIV negative/unknown partners. Specifically, intervention condition was associated with increased odds of zero male sex partners (AOR=3.03, 95%CI=1.26–7.28), condom use with male partners (AOR=2.64, 95%CI=0.95–7.36) and HIV negative/unknown status partners (AOR=3.19, 95%CI=0.98–10.38) at follow-up. These results contribute to the limited number of culturally appropriate models of HIV prevention intervention that are urgently needed for African American men who have sex with men to address their persistently high rates of HIV.

  13. Origins of fine aerosol mass in the Baltimore-Washington corridor: implications from observation, factor analysis, and ensemble air parcel back trajectories

    Antony Chen, L.-W.; Doddridge, Bruce G.; Dickerson, Russell R.; Chow, Judith C.; Henry, Ronald C.

    Chemically speciated fine particulate matter (PM 2.5) and trace gases (including NH 3, HNO 3, CO, SO 2, NO y) have been sampled at Fort Meade (FME: 39.10°N, 76.74°W; elevation 46 m MSL), Maryland, since July 1999. FME is suburban, located in the middle of the Baltimore-Washington corridor, and generally downwind of the highly industrialized Midwest. The PM 2.5 at FME is expected to be of both local and regional sources. Measurements over a 2-year period include eight seasonally representative months. The PM 2.5 shows an annual mean of 13 μg m -3 and primarily consists of sulfate, nitrate, ammonium, and carbonaceous material. Day-to-day and seasonal variations in the PM 2.5 chemical composition reflect changes of contribution from various sources. UNMIX, an innovative receptor model, is used to retrieve potential sources of the PM 2.5. A six-factor model, including regional sulfate, local sulfate, wood smoke, copper/iron processing industry, mobile, and secondary nitrate, is constructed and compared with reported source emission profiles. The six factors are studied further using an ensemble back trajectory method to identify possible source locations. Sources of local sulfate, mobile, and secondary nitrate are more localized around the receptor than those of other factors. Regional sulfate and wood smoke are more regional and associated with westerly and southerly transport, respectively. This study suggests that the local contribution to PM 2.5 mass can vary from <30% in summer to >60% in winter.

    A combined epidemiological exposure panel study was conducted during the summer of 1998 in Baltimore, Maryland. The objectives of the exposure analysis component of the 28-day study were to investigate the statistical relationships between particulate matter (PM) and related co-pollutants from numerous spatial boundaries associated with an elderly population, provide daily mass concentrations needed for the epidemiological assessment, and perform an extensive personal exposure assessment. Repeated 24-h integrated PM2.5 (n=394) and PM10 (n=170) data collections corresponding to stationary residential central indoor, individual apartment, residential outdoor and ambient monitoring were obtained using the same sampling methodology. An additional 325 PM2.5 personal air samples were collected from a pool of 21 elderly (65+ years of age) subjects. These subjects were residents of the 18-story retirement facility where residential monitoring was conducted. Mean daily central indoor and residential apartment concentrations were approximately 10 microg/m3. Outdoor and ambient PM2.5 concentrations averaged 22 microg/m3 with a daily range of 6.7-59.3 microg/m3. The slope of the central indoor/outdoor PM2.5 mass relationship was 0.38. The average daily ratio of PM2.5/PM10 mass concentrations across the measurement sites ranged from 0.73 to 0.92. Both the central indoor and mean apartment PM2.5 mass concentrations were highly correlated with the outdoor variables (r>0.94). The lack of traditionally recognized indoor sources of PM present within the facility might have accounted for the high degree of correlation observed between the variables. Results associated with the personal monitoring effort are discussed in depth in Part 2 of this article. PMID:11140436

    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.

  19. School placement for human immunodeficiency virus-infected children: the Baltimore City experience.

    1992-05-01

    Over the past 6 years, the city of Baltimore has successfully implemented a school placement policy for human immunodeficiency virus (HIV)-infected children and children with acquired immunodeficiency syndrome (AIDS). Both policy and specific procedures are based on nationally promulgated guidelines. School placement policy is part of an overall AIDS policy that includes education of students and staff and adoption of universal precautions to prevent transmission of communicable diseases in school. Implementation has been marked by excellent collaboration between the departments of health and education. Important policy components include expedited clinical investigation of each case, an interagency review panel, strict protection of confidentiality, a restricted setting for certain children, a school site visit for each placement, and continued monitoring of the school placement by school nurses. Many HIV-infected students need special educational services and/or school health services. The Baltimore City school placement process has avoided the exaggerated publicity endured by some communities, where media reporting has aggravated community fears and invaded the lives of families with HIV-infected children. Baltimore City has succeeded in ensuring access to education, protecting families' confidentiality, and providing special care for HIV-infected students. Local communities should emphasize national guidelines in designing school placement policies for HIV-infected children. School placement policies work best in the context of a comprehensive policy incorporating AIDS education and care. PMID:1579392

    The E.P.A. has declared the Baltimore Harbor as an impaired waterway, due to elevated levels of persistent pollutants. This concern coupled with recent changes to TMDL permitting requirements has made it essential to understand and quantify the sources of organic contamination. To complement ongoing hydrodynamic modeling efforts, an advanced multivariate statistical method was employed to assess the major factors influencing the distribution of organic contaminants in the harbor. Positive Matrix Factorization (PMF) was used to interpret the seasonal and spatial patterns of 30 PAHs and 10 PCB homolog groups in Baltimore Harbor. Both the particulate and dissolved PAH and PCB homolog fractions, as well as, water quality parameters such as POC, DOC and chlorophyll a were incorporated in this three-dimensional analysis. PMF has been used successfully several times to determine sources of atmospheric pollutants, but only once in water quality analysis. PMF offers several advantages over traditional source modeling including constraints on non-negative solutions. The data used in this analysis was collected as part of the Comprehensive Harbor Assessment and Regional Modeling Study (CHARM) in which water and particulate samples were collected from 26 sites in Baltimore Harbor during the fall and winter of 1999 and spring and summer of 2000.

    Background Among Hispanics, lung cancer is the leading cause of cancer-related death for men and the second leading cause of cancer death for women in the United States. Despite recent growth in Baltimore City’s Hispanic population, few data exist on tobacco use behaviors in this group. Objectives The present research sought to explore the social and environmental influences and norms that encourage or discourage tobacco use among Hispanic young adults in Baltimore. Methods In collaboration with several community stakeholders, we conducted focus groups with Hispanic young adults 18 to 24 years old. Participants were recruited from a community-based service organization and invited to take part in one of four focus groups segregated by gender. Results A total of 13 young men and 11 young women participated. Data from these focus groups indicate that cultural identity and gender norms leverage substantial influence in young adults’ decision about whether, where, and with whom to smoke. The data also suggest multiple social and familial influences on their smoking and nonsmoking behaviors. Participants identified smoking practices and clear brand preferences that they feel distinguish Hispanics from other racial and ethnic groups. Despite acknowledging the high price of cigarettes, cost was not mentioned as a factor influential in their smoking decisions. Conclusion These results provide essential guidance for the development of appropriate tobacco prevention and cessation intervention strategies and policy recommendations to eliminate tobacco use among Hispanic young adults in Baltimore.

    This paper evaluates the network architectures, the innovation in optical (WDM) system design, and the related transport technologies that have enabled metropolitan networks to scale to hundreds Gb/s of capacity, and to hundreds km of reach, meeting the diverse service needs of enterprise and residential applications, while maintaining cost lower than traditional long-haul optical transport. The analysis have lead to the development of a multi-service WDM system scalable to more than 300 Gb/s, and 500 km, exceeding the previous related demonstrations in reach and network (OADM) complexity. The most important performance achievements are summarized. The paper finally discusses future important technologies that hold promise to further enhance the cost-effectiveness of metropolitan optical systems.

    Different from Taipei, the metropolitan Kaohsiung which is a coastal and industrial city has the major pollution sources from stationary sources such as coal-fired power plants, petrochemical facilities and steel plants, rather than mobile sources. This study was an attempt to conduct a comprehensive and systematical examination of the holiday effect, defined as the difference in air pollutant concentrations between holiday and non-holiday periods, over the Kaohsiung metropolitan area. We documented evidence of a "holiday effect", where concentrations of NOx, CO, NMHC, SO2 and PM10 were significantly different between holidays and non-holidays, in the Kaohsiung metropolitan area from daily surface measurements of seven air quality monitoring stations of the Taiwan Environmental Protection Administration during the Chinese New Year (CNY) and non-Chinese New Year (NCNY) periods of 1994-2010. Concentrations of the five pollutants were lower in the CNY than in the NCNY period, however, that of O3 was higher in the CNY than in the NCNY period and had no holiday effect. The exclusion of the bad air quality day (PSI > 100) and the Lantern Festival Day showed no significant effects on the holiday effects of air pollutants. Ship transportation data of Kaohsiung Harbor Bureau showed a statistically significant difference in the CNY and NCNY period. This difference was consistent with those found in air pollutant concentrations of some industrial and general stations in coastal areas, implying the possible impact of traffic activity on the air quality of coastal areas. Holiday effects of air pollutants over the Taipei metropolitan area by Tan et al. (2009) are also compared.

    Focusing on micro-level processes of residential segregation, this analysis combines data from the Panel Study of Income Dynamics with contextual information from three censuses and several other sources to examine patterns of residential mobility between neighborhoods populated by different combinations of racial and ethnic groups. We find that despite the emergence of multiethnic neighborhoods, stratified mobility dynamics continue to dominate, with relatively few black or white households moving into neighborhoods that could be considered multiethnic. However, we also find that the tendency for white and black households to move between neighborhoods dominated by their own group varies significantly across metropolitan areas. Black and white households’ mobility into more integrated neighborhoods is shaped substantially by demographic, economic, political, and spatial features of the broader metropolitan area. Metropolitan-area racial composition, the stock of new housing, residential separation of black and white households, poverty rates, and functional specialization emerge as particularly important predictors. These macro-level effects reflect opportunities for intergroup residential contact as well as structural forces that maintain residential segregation. PMID:22753955

    2011-12-01

    The University of Maryland Three Meter Geodynamo experiment is the largest and most powerful in a series of experiments designed to achieve a self-excited magnetic field from a turbulent liquid metal model of a planetary core. The Three Meter experiment consists of concentric, independently rotating spherical boundaries of radius ratio 0.35 with an outer boundary diameter of nearly 3m. The gap between the spheres is filled with 13,000L of liquid sodium metal. The device allows access to regimes of turbulent hydromagnetic flow dominated by rapid rotation (with Ekman number ν /2Ω L2 lower than 10-8) and achieving high magnetic Reynolds number (Rm=UL/η ) exceeding that estimated in Earth's core (300-500). We have undertaken a series of mechanical tests and hydrodynamic investigations in water, including a systematic study of flows forced by the precession of the container axis as Earth rotates. These precession-driven flows are dominated by the spinover inertial mode and exhibit internal shear layers. Additional experiments in the sheared flow of water between the spheres show a wide variety of phenomena, including turbulent bi-stability and unusual angular momentum transport. The hydrodynamic investigations and mechanical tests have been successfully completed, and we have made substantial progress toward experiments with sodium. We report the continuing progress in our campaign to carry out hydromagnetic experiments, hopefully including observation of dynamo action.

    The forests of Maryland have been mapped at a scale of 1:250,000 on the basis of 15 regional associations: (1) tamarack, (2) bald cypress, (3) hemlock-yellow birch-black birch, (4) river birch-sycamore, (5) sycamore-green ash-box elder-silver maple, (6) shingle oak, (7) chestnut oak-post oak-blackjack oak, (8) chestnut oak-bear oak, (9) chestnut oak, (10) loblolly pine, (11) basket oak-lobolly pine, (12) willow oak-loblolly pine, (13) basket oak, (14) sugar maple-basswood, and (15) tulip poplar. The associations differ from each other in species composition and in abundances of species common to many associations. Each was identified in the field by the presence of relatively few common discontinuous tree species referred to as characteristic species. Correlations between forest associations and geologic, topographic, and soils units mapped at a similar scale suggest that patterns of available water are important in controlling distribution of woody species throughout Maryland.

  16. 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 a city-wide intervention in its public markets. PMID:23837722

    This article explores the potential of a GIS-based approach to city management - Baltimore's CitiStat e-government program - for meeting the goals of sustainable urban regeneration. The argument advocated here builds on the widely held recognition that the application of ICTs in general can lead to both new forms of inclusion and exclusion of citizens. Therefore attending to the 'digital divide' is a relevant issue because cities are complex environments where outcomes of interventions are uncertain and widening participative arenas to different actors can increase the possibilities to regenerate declining urban areas in a more democratic way.

  17. Managing multihazards risk in metropolitan USA

    NASA Astrophysics Data System (ADS)

    Aktan, A. Emin; Comfort, Louise K.; Shanis, Donald S.

    2003-07-01

    This proposal outlines an action plan for risk management in the Delaware Valley Metropolitan Region. This plan is consistent with the goals for strengthening homeland security announced by President Bush, and is designed to complement efforts currently under development by Pennsylvania Emergency Management Agency and Department of Health. This plan proposes the formation of a Delaware Valley Risk Management Consortium, representing the critical disciplines and organizations related to risk assessment and management. This group would have membership from academic institutions, government agencies, industry, and nonprofit organizations. This Consortium would develop a systemic scope of work with the appropriate recommendations for technology acquisition, development and integration with risk management policies and procedures. This scope of work would include the development of two related information systems for the Delaware Valley Region. The first would be a comprehensive 'health monitoring' system to assess the continuity of operations, which would use integrated remote sensing and imaging, information gathering, communication, computation, and, information processing and management over wide-area networks covering the entire metropolitan area. The second would use real-time information from the health monitoring system to support interactive communication, search and information exchange needed to coordinate action among the relevant agencies to mitigate risk, respond to hazards and manage its resources efficiently and effectively.

  18. Land-use Effect on Stream Organic Matter Composition in Two Metropolitan Areas in USA

    NASA Astrophysics Data System (ADS)

    Duan, S.; Kaushal, S.; Amon, R. M.; Brinkmeyer, R.

    2011-12-01

    Urbanization is a form of land-use change that is increasing in coastal watersheds and may affect the quantity and quality of organic carbon delivered to streams and coastal ocean. Here, we examine the changes in optical and isotopic characteristics of organic matter in streams (Gwynns Fall and Buffalo Bayou) draining Baltimore and Houston Metropolitan Areas (USA), relative to nearby less affected forested watersheds. A summer longitudinal sampling in Gwynns Fall along a rural-urban gradient showed increases in dissolved organic carbon (DOC) and fluorescent protein to humic ratio but a decrease in specific UV absorption (SUVA). Parallel Factor modeling shows dominance of terrestrial component of DOC, and the ratio of an unknown component to the component of humic substance was high in urban watersheds and it was positively correlated impervious surface cover (an index of urbanization). Incubation experiments with leaves and stream algae suggest origin of decayed leaf leachate of this component. Conversely, DOM in Buffalo Bayou showed higher intensity of protein-like fluorescence, and the intensity increased longitudinal along a rural-urban gradient but decreased from low-flows to a flooding event. The difference in fluorescent organic matter composition between the two streams probably reflected different management of wastewater in watersheds. Surface sediment collected at sites of sub-watersheds of Gwynns Fall showed changes in particle size, elemental and isotopic composition with land use. Sediment incubations showed that higher temperature (due to urban heat island effect) enhanced loss of labile organic matter and release of refractory organic matter into stream water. Release of reactive soluble phosphorus, loss of nitrogen and reduction of sulfate also occurred at high incubating temperatures, along with mineralization of sediment organic matter. Bed sediment collected along Buffalo Bayou displayed a longitudinal decrease in N-15, probably reflecting the displacement of waste water treatment plant in upper watershed. Organic matter compositions of suspended sediment, however, were more related to abundance of phytoplankton biomass.

  19. Selection of western Maryland streams for mitigation of acidification

    SciTech Connect

    Gerritsen, J.; Janicki, A.J.; Kazyak, P.; Heimbuch, D.

    1992-08-01

    A large proportion of streams in western Maryland are subject to acidification and subsequent loss of biological resources. A decision support approach was applied to aid in selecting streams as candidates for liming to mitigate effects of acidification. The objective of mitigation is restoration and protection of balanced populations of indigenous fish and invertebrates. Stream water chemistry, watershed area, and land use information were obtained for 285 stream reaches from three existing surveys (the 1987 Maryland Synoptic Stream Chemistry Survey, the 1989 Western Maryland Stream Survey, and a 1988 USGS Catoctin Stream Study). Reaches selected were concentrated in Garrett County (11 reaches), with four reaches occurring in Frederick County and three reaches in Allegany County.
