Baltimore, Maryland  

NASA Technical Reports Server (NTRS)

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).

Size-resolved fine and ultrafine particle composition in Baltimore, Maryland  

NASA Astrophysics Data System (ADS)

The third-generation real-time single-particle mass spectrometer (RSMS-3) was deployed from March to December 2002 in Baltimore, Maryland, as part of the Baltimore Particulate Matter Supersite. The site was located to the east of the downtown area and northwest of many local industrial emission sites. RSMS-3 actively sampled and analyzed over 380,000 individual particles within the 48-770 nm size range. The resulting positive and negative ion spectra for each particle were classified using a neural network algorithm, adaptive resonance theory ART 2-a. A subset of these data, particles analyzed between 1 April and 30 November 2003, is presented here. Over 99% of these particles could be described by 10 major composition types. Ambient number concentrations were determined for each type and correlated with particle size, wind direction, and time of day/year. On the basis of this information, local and regional sources of different composition classes are postulated. Almost 40% of all particles in the Baltimore aerosol are internally mixed, consisting primarily of organic carbon, ammonium nitrate, and ammonium sulfate. Most of these particles are likely derived from regional sources. The remaining particles appear to be derived mainly from local sources and processes and include elemental carbon (almost 30%), ammonium nitrate (over 10%), and various metals (over 20%). The particle composition types found in Baltimore aerosol are compared to previous measurements in Houston and Atlanta.

An exposure assessment study of ambient heat exposure in an elderly population in Baltimore, Maryland.  

PubMed Central

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.

Creating a transdisciplinary research center to reduce cardiovascular health disparities in Baltimore, Maryland: lessons learned.  

PubMed

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

Urbanization and the Regional Rainfall Climatology of the Baltimore Metropolitan Region  

NASA Astrophysics Data System (ADS)

A 10-year, high-resolution rainfall data set for the Baltimore metropolitan region is used to examine urbanization effects on the regional rainfall climatology and associated elements of the urban water cycle. Rainfall fields are developed at 1 km spatial resolution and 15-minute time resolution based on radar reflectivity observations from the Sterling, VA WSR-88D radar and rain gage observations from diverse networks in the region. The warm season (June - August) rainfall climatology for the Baltimore region exhibits sharp spatial gradients in a diverse array of statistical properties characterizing mean rainfall, rainfall extremes and rainfall occurrence. In addition to urbanization effects, these properties are linked to the effects of mountainous terrain to the west and land-water boundaries to the east. The rainfall data set covers the principal study watersheds of the Baltimore Ecosystem Study (BES; a component of the NSF LTER program). Analyses of urbanization impacts on the storm event water balance are carried out for gaged watersheds in the BES region.

A community care initiative: Maryland and Hopkins students take to the streets in Baltimore City.  

PubMed

Medical students from University of Maryland and Johns Hopkins University, with a grant from the Maryland Chapter of the American College of Physicians, held a free health fair in a Baltimore City neighborhood. The goals were to heighten awareness of common health problems, learn more about a medically underserved community, and increase access to primary care services in that community. The students planned booths to offer information and screening on 19 common health topics. Fair organizers worked with a local clinic, People's Community Health Center, and a neighborhood development organization, the Safe and Smart Center, to create an event that would engage and educate people on relevant issues. Approximately 100 medical students participated in the event and 350 people attended the fair. An optional survey filled out by fair participants revealed that a diverse group of people attended the event. Comments about the day from medical students and fair participants show that the event was enjoyable and offered a tremendous learning opportunity for both groups. This paper also discusses problems that arose during the planning stages as well as suggestions for those interested in planning a similar event. PMID:10048282

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

PubMed

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

"This is Our Sanctuary": Perceptions of Safety among Exotic Dancers in Baltimore, Maryland  

PubMed Central

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.

Scaling properties of air pollution in Athens, Greece and Baltimore, Maryland  

NASA Astrophysics Data System (ADS)

Detrended fluctuation analysis is applied to the Athens air-pollution time-series consisting of hourly observations of ozone, nitrogen oxides, and particulate matter obtained at five air-pollution monitoring stations during 1987-2003. Persistent power-law correlations in the fluctuations of daytime and nighttime ozone concentrations with lag times ranging from 1 week to 5 years were detected with more intense correlations ("stronger memory") during daytime. The fluctuations of nitrogen oxide concentrations exhibit similar behavior. Finally, persistent power-law correlations from about 4 h to 9 months were found in PM10 fluctuations in Athens. Long-range correlations for lag times from about 4 h to 2 weeks were also detected for PM2.5 fluctuations in a 6-month data set collected at the University of Maryland "Supersite" in East Baltimore. Although the origin of the long-range behaviour of air-pollution merits further investigation, these findings presumably, reflect short and longer term source/meteorological features that are probably related to the self-organized critical behavior of the atmosphere. These findings provide power-law relationships which may substantially contribute to the development of more reliable simulating models for the ozone, nitrogen oxides, and particulate matter fluctuations.

Diagnosing horizontal gradients in aircraft soundings over the Baltimore metropolitan area during DISCOVER-AQ  

NASA Astrophysics Data System (ADS)

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.

Income, social stratification, class, and private health insurance: a study of the Baltimore metropolitan area.  

PubMed

Most studies of inequalities and access to health care have used income as the sole indicator of social stratification. Despite the significance of social theory in health insurance research, there are no empirical studies comparing the ability of different models of social stratification to predict health insurance coverage. The aim of this study is to provide a comparative analysis using a variety of theory-driven indicators of social stratification and assess the relative strength of the association between these indicators and private health insurance. Data were collected in a 1993 telephone interview of a random digit dialing sample of the white population in the Baltimore Metropolitan Statistical Area. Indicators of social stratification included employment status, full-time work, education, occupation, industry, household income, firm size, and three types of assets: ownership, organizational, and skill/credential. The association between social stratification and private health insurance was strongest for those having higher household incomes, having attained at least a bachelor's degree, and working in a firm with more than 50 employees, followed by being an owner or manager, and by being employed. The addition of education and firm size improved the prediction of the household income model. The authors conclude that studies of inequalities in health insurance coverage can benefit from the inclusion of theory-driven indicators of social stratification such as human capital, labor market segmentation, and control over productive assets.

Extreme hydrometeorological events and the urban environment: Dissecting the 7 July 2004 thunderstorm over the Baltimore MD Metropolitan Region  

NASA Astrophysics Data System (ADS)

Observational analyses and mesoscale modeling studies, using the Weather Research and Forecasting (WRF) model, are used to dissect the mechanisms associated with record lightning, rainfall, and flooding over the Baltimore metropolitan region on 7 July 2004. Storm evolution on 7 July 2004 exhibited characteristic features of warm season thunderstorms producing flash flooding over the Baltimore-Washington DC metropolitan region. The storm system was initiated along the Blue Ridge mountains, with model simulations suggesting that convergence-induced spin-up of a meso-low was responsible for initial thunderstorm development. Observations and model analyses show that thermal effects associated with Chesapeake Bay had a pronounced impact on storm evolution and rainfall distribution. Analyses of radar reflectivity and lightning observations suggest that the urban environment played a significant role in storm evolution and heavy rainfall distribution. Model analyses show that urban canopy effects from both the Baltimore and Washington DC urban regions play an important role in determining the storm environment associated with heavy rainfall. Urban Heat Island effects did not play a significant role in the storm evolution. Observations of aerosols and drop-size distributions from a vertically pointing LIDAR and a disdrometer and model analyses suggest that the aerosols may have played an important role in stimulating efficient precipitation mechanisms and extreme rainfall rates for the 7 July 2004 storm.

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

NASA Astrophysics Data System (ADS)

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.

CAMx and CMAQ Model Intercomparison for July 2011 in the Baltimore-Washington Metropolitan Region  

NASA Astrophysics Data System (ADS)

A comprehensive set of atmospheric trace gas observations is available for July 2011 in the Baltimore-Washington metropolitan region as part of NASA's DISCOVER-AQ air quality campaign. Observations of trace gases during the campaign include: ozone, volatile organic compounds (VOCs), reactive nitrogen species (NOx and NOy), carbon monoxide (CO), and methane (CH4), among other trace gas species. This dataset is extremely valuable due to the high temporal resolution of observations over a concentrated area. Observations of trace gases have been compared to 12-km simulations of the Community Multiscale Air Quality (CMAQ) model v5.0 and the Comprehensive Air-Quality Model with Extensions (CAMx) v5.40. Both models are initialized with the same WRF meteorology that was completed off-line. Both models also use the same CB05 gas-phase chemical mechanism. The goal of the model intercomparison is to determine how well the two simulations model the amount, transport and lifetime of the precursors to ozone. Preliminary results show that ozone observations over the region during the afternoon match model output with a standard error within 10% from both the CMAQ and CAMx models. However, trace gas measurements of reactive nitrogen (NOy) and isoprene (ISOP) are often off by a factor of 2 in both models. Reasons for these errors will be explored. A model-to-model only intercomparison is also performed and shows some differences especially in urban plumes and convective regions. The two models have different vertical diffusion parameterizations, which may partially account for these disparities.

Solar ultraviolet-B radiation in urban environments: the case of Baltimore, Maryland.  

PubMed

Ultraviolet-B radiation (UV-B, 280-320 nm) has important effects in urban areas, including those on human health. Broadband UV-B radiation is monitored in Baltimore, MD, as part of the Baltimore Ecosystem Study, a long-term ecological research program. We compare broadband UV-B irradiance in Baltimore with UV-B at two nearby locations: a more rural station 64 km southeast and a suburban station 42 km southwest. The monitoring station in Baltimore is on the roof of a 33-m-tall building; there are no significant obstructions to sky view. The U.S. Department of Agriculture UV-B Monitoring and Research Program provided all sensors, which were calibrated at the National Oceanic and Atmospheric Administration Central UV Calibration Facility. UV-B irradiances at the three sites generally were similar. Over all conditions, Baltimore and the suburban site measured 3.4% less irradiance than the rural site. This difference is within the anticipated +/-3% calibration uncertainty of the pyranometers. On 59 days with cloud-free conditions at all three sites, average differences in measured UV-B among the three sites were even smaller; Baltimore measured 1.2% less irradiance than the rural site. High aerosol optical thickness strongly reduced daily UV-B dose, whereas [SO2] had no influence. Surface O3 increased with increasing UV-B dose when [NO2] exceeded 10 ppb. PMID:15623324

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

USGS Publications Warehouse

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.

Superfund Record of Decision (EPA Region 3): Kane and Lombard Site, Baltimore, Maryland (first remedial action), September 1987. Final report  

SciTech Connect

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

Relationships between pediatric asthma and socioeconomic/urban variables in Baltimore, Maryland  

NASA Technical Reports Server (NTRS)

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.

Risks of Recreational Exposure to Waterborne Pathogens Among Persons With HIV/AIDS in Baltimore, Maryland  

PubMed Central

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

Injection drug users' and their risk networks experiences of and attitudes toward drug dealer violence in Baltimore, Maryland  

PubMed Central

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

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

NASA Astrophysics Data System (ADS)

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

Survival during Renal Replacement Therapy among African Americans Infected with HIV Type 1 in Urban Baltimore, Maryland  

PubMed Central

Background African Americans with human immunodeficiency virus type 1 (HIV-1) infection and kidney disease are at increased risk of end-stage renal disease requiring renal replacement therapy (RRT), particularly in urban areas with high rates of poverty and injection drug use. It is unknown how the widespread use of highly active antiretroviral therapy (HAART) has affected survival during RRT in this vulnerable population. Methods African American patients infected with HIV-1 who required RRT were identified from 2 cohorts that included 4509 Africans Americans infected with HIV-1 who were recruited during the period 1988–2004 in Baltimore, Maryland. Survival after initiation of RRT was compared for those who initiated treatment in the pre-HAART and the HAART eras using Kaplan-Meier curves. Cox proportional hazards regression analysis was used to adjust for potential confounders. Results RRT was initiated in 162 patients (3.6%) during 10.6 years of follow-up (119 during the HAART era). Compared with patients who started RRT in the pre-HAART era, those in the HAART era were older (P< .001) and more likely to have CD4 cell counts of ?200 cells/mm3 (P = .01). A total of 126 patients (78%) died during follow-up; among those who initiated RRT during the HAART era, 87 deaths occurred (73%). Median survival time in the pre-HAART era was 22.4 months (95% confidence interval [CI], 9.3–30.7); during the HAART era, it was 19.9 months (95% CI, 14.7–26.5; P = .94). In the multiple Cox regression model, factors independently associated with increased mortality included age (hazard ratio [HR], 1.30; 95% CI, 1.06–1.60; P = .01), lower serum albumin level (HR, 0.72; 95% CI, 0.57–0.91; P< .007), lower CD4 cell count (HR, 0.90; 95% CI, 0.82–0.99; P< .03), and the lack of HAART (HR, 0.52; 95% CI, 0.33–0.82; P = .005). Conclusions Older age, lower serum albumin level, lower CD4 cell count, and the lack of HAART are independent predictors of poor survival among African Americans infected with HIV-1 undergoing RRT in a resource-limited urban area. RRT survival was similar in the pre-HAART and HAART eras, likely reflecting inadequate HIV treatment in this population.

Object-based Land Cover Classification and Change Analysis in the Baltimore Metropolitan Area Using Multitemporal High Resolution Remote Sensing Data  

PubMed Central

Accurate and timely information about land cover pattern and change in urban areas is crucial for urban land management decision-making, ecosystem monitoring and urban planning. This paper presents the methods and results of an object-based classification and post-classification change detection of multitemporal high-spatial resolution Emerge aerial imagery in the Gwynns Falls watershed from 1999 to 2004. The Gwynns Falls watershed includes portions of Baltimore City and Baltimore County, Maryland, USA. An object-based approach was first applied to implement the land cover classification separately for each of the two years. The overall accuracies of the classification maps of 1999 and 2004 were 92.3% and 93.7%, respectively. Following the classification, we conducted a comparison of two different land cover change detection methods: traditional (i.e., pixel-based) post-classification comparison and object-based post-classification comparison. The results from our analyses indicated that an object-based approach provides a better means for change detection than a pixel based method because it provides an effective way to incorporate spatial information and expert knowledge into the change detection process. The overall accuracy of the change map produced by the object-based method was 90.0%, with Kappa statistic of 0.854, whereas the overall accuracy and Kappa statistic of that by the pixel-based method were 81.3% and 0.712, respectively.

Ensemble statistical post-processing of the National Air Quality Forecast Capability: Enhancing ozone forecasts in Baltimore, Maryland  

NASA Astrophysics Data System (ADS)

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 costly decisions that the NAQFC couldn't provide alone.

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

PubMed Central

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.

Reconciling Latent and Sensible Energy Fluxes with Footprints in a Heterogeneous Landscape at an Urban-suburban Tower near Baltimore, Maryland  

NASA Astrophysics Data System (ADS)

Measurements of eddy-fluxes in an urban-suburban landscape may create technical difficulties as latent and sensible energy fluxes in the tower’s footprint are non-uniform. In an earlier study, we have found that the average vegetation cover surrounding the Cub Hill tower was 64 %; ranging from 46 to 77 % among 8 wind directions. We measured latent and sensible energy fluxes using a closed-path eddy-covariance system in the Cub Hill tower near Baltimore, Maryland. Half-hourly values of latent and sensible energy fluxes were stratified according to 24 15-degree bins of wind direction in each of the 16-day compositing periods for Normalized Difference Vegetation Index (NDVI) during 3 years of study (2004 to 2006). We used the daytime latent and sensible energy fluxes in the multivariate regression analyses to model fluxes of water vapor or evapotranspiration (ET) and sensible heat (H) as functions of micrometeorological variables (net radiation, temperature, relative humidity, wind speed, and soil moisture), NDVI, and land cover. Empirical models are developed at 16-day intervals for each of the 24 bins of wind direction to establish the relationships between energy fluxes (i.e., latent and sensible) and footprints (i.e., micrometeorology, NDVI, and land cover) around the Cub Hill tower.

Linking Nocturnal Eddy Fluxes to Land Use-Land Cover in a Heterogeneous Landscape Surrounding the Urban-suburban Tower near Baltimore, Maryland  

NASA Astrophysics Data System (ADS)

Anthropogenic activities in urban ecosystems represent the key driving force for local and regional climate change scenarios, producing the various pollutants that cause environmental change at the global scale: elevated carbon dioxide (CO2), increased ozone and nitrogen deposition, and elevated temperatures. Measurements of eddy fluxes in an urban-suburban landscape pose technical difficulties as sinks and sources of CO2 surrounding the tower are non-uniform. In a recent study, we stratified half-hourly values of eddy fluxes, i.e., carbon dioxide (Fco2), latent energy (LE), and sensible heat (H), according to wind sectors. Additionally, remotely sensed (spatial) data were stratified according to wind sectors around the Cub Hill tower near Baltimore, Maryland. We found that diurnal eddy fluxes were empirically dependent on remotely sensed metrics within the two-kilometer radius surrounding the tower. We hypothesized that nocturnal eddy fluxes, as stratified into wind sectors, will be similarly dependent on the land use-land cover (LULC). In the present study, we pooled the nocturnal half-hourly eddy fluxes during a 6-year period (2004-09) into a single data set, and stratified the data according to 24 wind sectors representing the wind direction during each half-hourly eddy flux measurement. We ask the following questions: 1) Are the nocturnal eddy fluxes inter-dependent with each other? 2) Do the average nocturnal eddy fluxes on a daily basis differ between wind sectors? 3) Which micrometeorological variables determine the differences in eddy fluxes between wind sectors? 4) Do differences in nocturnal eddy fluxes among wind sectors depend upon LULC? 5) Are the relationships between nocturnal eddy fluxes and LULC consistent during Winter, Spring, Summer, and Fall? and 6) How do these nocturnal urban-suburban eddy fluxes compare with the nocturnal eddy fluxes in a nearby mixed deciduous rural forest? Results from the data analyses will be presented and discussed.

Evaluation of 3-D Air Quality System Remotely-Sensed Aerosol Optical Depth for the Baltimore/Washington Metropolitan Air Shed  

NASA Astrophysics Data System (ADS)

Integrating satellite- and ground-based aerosol optical depth (AOD) observations with surface total fine particulate (PM2.5) and sulfate concentrations allows for a more comprehensive understanding of local- and urban-scale air quality. This study evaluates the utility of integrated databases being developed for NOAA and EPA through the 3D-AQS project by examining the relationship between remotely-sensed AOD and PM2.5 concentrations for each platform for the summer of 2004 and the entire year of 2005. We compare results for the Baltimore, MD/Washington, DC metropolitan air shed, incorporating AOD products from the Terra and GOES-12 satellites, AERONET sunphotometer, and ground-based lidar, and PM2.5 concentrations from five surface monitoring sites. The satellite-derived products include AOD from the Moderate Resolution Imaging Spectroradiometer (MODIS) and Multi-angle Imaging Spectroradiometer (MISR), as well as the GOES Aerosol/Smoke Product (GASP). The vertical profile of lidar backscatter is used to retrieve the planetary boundary layer (PBL) height in an attempt to capture only that fraction of the AOD arising from near surface aerosols. Adjusting the AOD data using platform- and season-specific ratios, calculated using the parameters of the regression equations, for two case studies resulted in a more accurate representation of surface PM2.5 concentrations when compared to a constant ratio that is currently being used in the NOAA IDEA product. This work demonstrates that quantitative relationships between remotely-sensed and in-situ aerosol observations in an integrated database can be computed and applied to improve the use of remotely-sensed observations for estimating surface concentrations.

ELF and ALEX SURF WINTER WAVES: Lidar Intercomparison of Aerosol and Water Vapor Measurements in the Baltimore-Washington Metropolitan Area During the Winter Water Vapor Validation Experiments (WAVES) 2008 campaign.  

NASA Astrophysics Data System (ADS)

Elastic and Raman lidar measurements were conducted to measure the vertical distribution of aerosols and water vapor during the Water Vapor Validation Experiments (WAVES) 2008 campaign by the University of Maryland Baltimore County (UMBC) Atmospheric Lidar Group at UMBC, at the same time as measurements at Howard University's Beltsville Research Station (26.5 km distant). The lidar profiles of atmospheric water vapor and aerosols allowed comparison for AURA/Aqua retrieval studies, by performing instrument accuracy assessments and data, generated by various independent active and passive remote sensing instruments for case studies of regional water vapor and aerosol sub-pixel variability. Integration of the lidar water vapor mixing ratios has been carried out to generate a column precipitable water vapor timeseries that can be compared to UMBC's SUOMINET station and Baltimore Bomem Atmospheric Emitted Radiance Interferometer (BBAERI). Changes in atmospheric aerosol concentration and water vapor mixing ratios due to meteorological events observed in the lidar timeseries have been correlated to the vertical temperature timeseries of BBAERI and to modeling of the air mass over the Baltimore-Washington metro area with the Weather Research and Forecasting (WRF) model.

Baltimore Ecosystem Study  

NSDL National Science Digital Library

Many ecologists work to understand how various parts of a given ecological system work or function with other systems in their vicinity, but relatively few attempt to bring together all of this work with major urban areas. One such impressive project is the Baltimore Ecosystem Study, which aims to understand metropolitan Baltimore as an ecological system; and in doing so, bring together researchers from the biological, physical and social sciences to work on this formidable task that is truly interdisciplinary. At the site, visitors can learn about the staff of the project and read about its various thematic areas of inquiry, including biodiversity, education, soil, stream and watershed studies, and vegetation. A good place to start before diving into the numerous research projects would be the research area, which explains the basic goals of the project, the theories that the research team is drawing on, and the central questions of its work. The Baltimore Ecosystem Study has also been approved for use in classrooms by the American Association for the Advancement of Science, and educators will find materials that they can draw on to teach various concepts and ideas here as well.

In Situ Airborne CH2O Measurements Over the Baltimore/Washington DC Metropolitan Region during the DISCOVER-AQ Study  

NASA Astrophysics Data System (ADS)

The first deployment for NASA's Earth Venture campaign DISCOVER-AQ (Deriving Information on Surface conditions from Column and Vertically Resolved Observations Relevant to Air Quality) took place over the Baltimore/Washington DC region during July of 2011. Fast in situ measurements of CH2O were acquired during this study onboard the NASA WP3 aircraft employing a mid-infrared difference frequency generation absorption spectrometer. High resolution, sensitive, airborne measurements from 0.3-km above the surface to ~ 5km were repetitively acquired over 6 different ground monitoring sites at various times of the day. The observations revealed a high degree of variability from site to site, over the course of a day, and between days. In addition, CH2O was highly correlated with water vapor in the boundary layer. This presentation will discuss these observations as well as the derived vertical columns and correlations with CO, and OVOC species.

A comparison of three empirically based, spatially explicit predictive models of residential soil Pb concentrations in Baltimore, Maryland, USA: understanding the variability within cities.  

PubMed

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

Processes Controlling CH2O Over the Baltimore/Washington DC Metropolitan Region: A Box Model Analysis Using Data from DISCOVER-AQ  

NASA Astrophysics Data System (ADS)

The first deployment for NASA's Earth Venture campaign DISCOVER-AQ (Deriving Information on Surface conditions from Column and Vertically Resolved Observations Relevant to Air Quality) took place over the Baltimore/Washington DC region during July of 2011. Observations of CH2O in the lowest kilometer (pressure-altitude) indicate that median concentrations can vary day to day by as much as 5 ppbv. Further, variability within a single day can correlate with a number of species, including H2O, temperature, isoprene, and/or CO. The NASA Langley photochemical box model is used to examine the dominant budget terms for CH2O during DISCOVER-AQ and to diagnose the drivers of the CH2O variability. Modeling results show that the source of CH2O is largely dominated by isoprene. However, the variability of CH2O within single flight days is rarely directly correlated to isoprene. Rather, most often, CH2O variability is correlated to the oxidative capacity of the atmosphere, defined by OH and driven by OH precursors such as H2O, O3 photolysis rates, and NO. Sensitivity model runs where isoprene is held constant to daily medians show excellent ability to predict both the overall CH2O concentration (dominated by isoprene) and the variability of CH2O throughout a day (driven by variations in oxidative capacity).

Analysis of soil moisture patterns in forested and suburban catchments in Baltimore, Maryland, using high-resolution photogrammetric and LIDAR digital elevation datasets  

NASA Astrophysics Data System (ADS)

Field observations of near-surface soil moisture, collected over several seasons in a watershed in suburban Maryland, are compared with values of the topographic soil moisture index generated using digital elevation models (DEMs) at a range of grid cell sizes from photogrammetric and light detection and ranging (LIDAR) data sources. A companion set of near-surface soil moisture observations, DEMs and topographic index values are also presented for a nearby forested catchment. The degree to which topographic index values are an effective indicator of near-surface soil moisture conditions varies in the two environments. The urbanizing environment requires topographic index values from a DEM with a much finer grid cell resolution than the LIDAR data can provide, and the relationship is stronger in wetter conditions. In the forested environment, the DEM resolution required is considerably lower and adequately supported by the photogrammetric data, and the relationship is strong under all moisture conditions. These results provide some insights into the length scales of near-surface hydrological processes in the urbanizing environment, and the resolution of terrain data required to model those processes.

Statistical classification of hydrogeologic regions in the fractured rock area of Maryland and parts of the District of Columbia, Virginia, West Virginia, Pennsylvania, and Delaware  

USGS Publications Warehouse

Hydrogeologic regions in the fractured rock area of Maryland were classified using geographic information system tools with principal components and cluster analyses. A study area consisting of the 8-digit Hydrologic Unit Code (HUC) watersheds with rivers that flow through the fractured rock area of Maryland and bounded by the Fall Line was further subdivided into 21,431 catchments from the National Hydrography Dataset Plus. The catchments were then used as a common hydrologic unit to compile relevant climatic, topographic, and geologic variables. A principal components analysis was performed on 10 input variables, and 4 principal components that accounted for 83 percent of the variability in the original data were identified. A subsequent cluster analysis grouped the catchments based on four principal component scores into six hydrogeologic regions. Two crystalline rock hydrogeologic regions, including large parts of the Washington, D.C. and Baltimore metropolitan regions that represent over 50 percent of the fractured rock area of Maryland, are distinguished by differences in recharge, Precipitation minus Potential Evapotranspiration, sand content in soils, and groundwater contributions to streams. This classification system will provide a georeferenced digital hydrogeologic framework for future investigations of groundwater availability in the fractured rock area of Maryland.

DRAGONs DISCOVER Air Quality over Baltimore  

NASA Astrophysics Data System (ADS)

The AERONET program is addressing issues of high resolution aerosol validation and internal retrieval comparisons by establishing short-term mesoscale networks called Distributed Regional Aerosol Gridded Observation Network or DRAGON. The first, DRAGON-USA, was a mesoscale gridded network of 44 sun and sky scanning spectral photometers established in the Washington - Baltimore Metropolitan area at a grid spacing of approximately 10 km to assess the daytime aerosol spatial distributions during the summer of 2011. Concurrently the first of four Earth Venture Deriving Information on Surface Conditions from Column and VERtically Resolved Observations Relevant to Air Quality (DISCOVER AQ) campaigns, executed an intensive ground and airborne measurement campaign over the Washington-Baltimore I-95 corridor to improve remote sensing capabilities for near surface air quality assessment during July 2011. Contributing elements of this campaign include the NASA Langley airborne HSRL, ground based lidars, PM 2.5 and surface meteorology, and the Langley Aerosol Research Group Experiment (LARGE) in situ measurements on board the NASA P-3B. Repeat profiles were made over 6 supersites with AERONET observations on 14 flight days in July allowing numerous coincidences under a variety of aerosol conditions. Additional in and out of network profiles were flown over AERONET sites by the UMD Cessna 402B aircraft with in situ scattering and absorption measurements. These combined 4-D characterizations of optical, microphysical and chemical aerosol properties provide a comprehensive understanding of the relationships between AERONET derived aerosol properties and in situ measurements for fine mode dominated urban aerosols, assessment of new AERONET aerosol retrievals and further provides a detailed database for high resolution satellite and model validation. Preliminary results indicate a SSA ~0.02 lower along the I-95 corridor on heavily polluted days and AOD gradients highly variable under a variety of conditions including adjacent to moderate convective clouds. These and other comparisons to in situ and RS measurements will be illustrated as well as discussion of future DRAGON campaigns in east Asia.

Marylanders defeat Philadelphia: yellow fever updated.  

PubMed Central

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. This tale of two cities ends in peace. Images Fig. 1 Fig. 2 Fig. 3 Fig. 4 Fig. 5 Fig. 6 Fig. 7 Fig. 8 Fig. 10 Fig. 11

Lidar Measurements of Summer Low Level Jet Events over Baltimore  

NASA Astrophysics Data System (ADS)

Remote sensing of atmospheric aerosols and water vapor, in the lower troposphere, have been carried out at the University of Maryland, Baltimore County (UMBC) by the Atmospheric Lidar Group during summer low level jet events over Maryland for two years and especially during the Water Vapor Variability - Satellite/Sondes (WAVES) campaigns of 2006 and 2007. For lofted layers encountered the aerosol lidar ratio (Sa) was computed to determine the aerosol extinction and subsequently the optical depth. Aerosol stratification and disturbance of nocturnal boundary layer, observed by lidar at UMBC, was confirmed by Maryland Department of the Environment (MDE) wind profiler measurements. The vertical and horizontal distribution of the low level jet was identified with the Weather Research and Forecasting (WRF) model to characterize the nature and possible effects of the incoming low level jet air mass on surface ozone within the boundary layer. Ground measurements from MDE monitoring stations and lidar optical depth are compared to evaluate aerosol loading due to long range transport in the boundary layer.

Cogeneration for a utility-co-owned industrial park. Volume 3. Baltimore Gas and Electric site. Final report  

SciTech Connect

This volume of the report presents the methods and results of a study of one of four proposed industrial parks developed as a cogeneration customer of a utility owned electric generation station. The site is the Baltimore Gas and Electric, Marley Neck Site near Baltimore, Maryland. The concept studied consisted of extracting cold reheat steam from a 620-MW turbine generator cycle for the major share of the thermal energy and burning corporate solid waste and sewage sludge to produce a minor share of the thermal energy. The waste burner primary contribution to the project was in ''tipping fees'' for burning wastes. The concept studied was technically feasible and economically attractive.

Challenges in Urban Hydrologic Modeling: A Baltimore Case Study  

NASA Astrophysics Data System (ADS)

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.

Dissecting the 7 July 2004 storm over Baltimore, MD: Mesoscale modeling and observations  

NASA Astrophysics Data System (ADS)

On 7 July 2004, the Baltimore metropolitan region experienced a thunderstorm system that produced record flooding, rainfall and cloud-to-ground lightning strikes. In this study, model and observational analyses are carried out to analyze the hydrometeorology of the storm and understand the impacts of the urban environment and surrounding topography on storm evolution. Baltimore is an interesting setting for these analyses combining the urban environment with mountainous terrain to the west and the land-water interface to the east. Hydrometeorological analyses are based on volume scan reflectivity observations from the Baltimore International Airport Terminal Doppler Weather Radar and the Sterling, Virginia WSR-88D radar, cloud-to- ground lightning observations from the National Lightning Detection Network, raindrop spectra observations from a Joss-Waldvogel disdrometer and rainfall accumulations from a dense rain gage network operated as a component of the Baltimore Ecosystem Study. Numerical model analyses use the Weather Research Forecast (WRF) mesoscale model to examine the impact of land-use, topography and land-water boundaries on the initiation and evolution of the storm.

An examination of spatial concentrations of sex exchange and sex exchange norms among drug users in Baltimore, MD  

PubMed Central

Baltimore, Maryland consistently ranks highest nationally in rates of sexually transmitted diseases and HIV infection. Prior studies have identified geographic areas where STI and HIV infection in the city is most prevalent. It is well established that sex exchange behavior is associated with HIV and STIs, yet it is not well understood how sex exchangers are spatially distributed within the high-risk areas. We sought to examine the spatial distribution of individuals who report sex exchange compared to those who do not exchange. Additionally we examined the spatial context of perceived norms about sex exchange. Data for the study came from a baseline sample of predominately injection drug users (n=842). Of these, 21% reported sex exchange in the prior 90 days. All valid baseline residential addresses of participants living within Baltimore city boundaries were geocoded. The Multi-Distance Spatial Cluster Analysis (Ripley’s K-function) was used to separately calculate the K-functions for the addresses of participants reporting sex exchange or non-sex exchange, relative to the recruited population. Evidence of spatial clustering of sex exchangers was observed and norms aligned with these clusters. Of particular interest was the high density of sex exchangers in one specific housing complex of East Baltimore, which happens to be the oldest in Baltimore. These findings can inform targeted efforts for screening and testing for HIV and STIs and placement of both individual and structural level interventions that focus on increasing access to risk reduction materials and changing norms about risk behaviors.

Lagrangian sampling of 3-D air quality model results for regional transport contributions to sulfate aerosol concentrations at Baltimore, MD, in summer 2004  

NASA Astrophysics Data System (ADS)

We use ensemble-mean Lagrangian sampling of a 3-D Eulerian air quality model, CMAQ, together with ground-based ambient monitors data from several air monitoring networks and satellite (MODIS) observations to provide source apportionment and regional transport vs. local contributions to sulfate aerosol and PM 2.5 concentrations at Baltimore, MD, for summer 2004. The Lagrangian method provides estimates of the chemical and physical evolution of air arriving in the daytime boundary layer at Baltimore. Study results indicate a dominant role for regional transport contributions on those days when sulfate air pollution is highest in Baltimore, with a principal transport pathway from the Ohio River Valley (ORV) through southern Pennsylvania and Maryland, consistent with earlier studies. Thus, reductions in sulfur emissions from the ORV under the EPA's Clean Air Interstate Rule may be expected to improve particulate air quality in Baltimore during summer. The Lagrangian sampling of CMAQ offers an inexpensive and complimentary approach to traditional methods of source apportionment based on multivariate observational data analysis, and air quality model emissions separation. This study serves as a prototype for the method applied to Baltimore. EPA is establishing a system to allow air quality planners to readily produce and access equivalent results for locations of their choice.

Interaction between urbanization and climate variability amplifies watershed nitrate export in Maryland  

USGS Publications Warehouse

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.

Highly time-resolved organic and elemental carbon measurements at the Baltimore Supersite in 2002  

NASA Astrophysics Data System (ADS)

Organic carbon (OC) and elemental carbon (EC) in fine particles (PM2.5) were measured at the Baltimore Supersite at Ponca Street for 9.5 months in 2002 using a Sunset Laboratory carbon analyzer with 1-hour time resolution. Monthly EC and CO diurnal averages were characterized by pronounced peaks in the early morning commute hours. OC concentration profiles were similar to CO and EC during the morning and evening rush hours, except when high ozone episodes occurred, i.e., generally in summer. Primary and secondary OC contributions were estimated during ozone episodes exceeding 100 ppb (1-hour average). The largest 1-hour ozone concentrations for the entire study period occurred between 11 and 13 August, during which secondary OC contributed, on average, ˜60% of the hourly OC concentrations and a maximum of 82%. Additionally, the annual EC emission rate is estimated for Maryland using published CO emission inventory data and a mean EC/CO ratio (0.0023 ± 0.0008) derived by regressing selected EC and CO measurements for each of the 9.5 months. The result, 2.31 ± 0.80 Gg EC yr-1, is similar to the estimate (2.95 Gg EC yr-1), determined on the basis of the PM2.5 emission inventory for Maryland and the mean EC abundance in PM2.5 measured with a U.S. Environmental Protection Agency speciation monitor in 2002. Finally, the Baltimore Supersite and much of the northeastern United States experienced severe smoke fumigation in early July 2002 owing to uncontrolled forest fires in Quebec, during which time, CO, EC, and OC were predominately associated with the Canadian smoke. During this episode, EC emissions are estimated to be 4.75 Gg EC from Canadian Quebec natural fires in July, and an annual release rate of 9.94 Gg EC yr-1 is estimated for all Canadian boreal forest fires.

First Results from BBAERI: The Baltimore Bomem Atmospheric Emitted Radiance Interferometer  

NASA Astrophysics Data System (ADS)

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).

Water withdrawal and use in Maryland, 1986  

USGS Publications Warehouse

During 1986, about 1,460 million gallons per day of freshwater was withdrawn from the surface-, and groundwater resources of Maryland. In addition, more than 6,240 million gallons per day of saline surface water was withdrawn and used primarily for cooling purposes in the generation of electricity. Most freshwater withdrawals (84%) were from surface water sources and were withdrawn and used in the Potomac drainage basin, whereas most groundwater was withdrawn and used in the Upper Chesapeake drainage basin. The Potomac Group aquifers provided the most groundwater (56 million gallons per day). Ten water use categories comprise the major demands on the surface and groundwater resources of the State: public supply, domestic, commercial, industrial, mining, thermoelectric power generation, hydroelectric power generation, agricultural (non-irrigation), irrigation, and aquaculture. Public-supply systems withdrew the most water in the State (801 million gallon/day) for use by residents, commercial establishments, and industries. Baltimore City had the largest public-supply use in 1986 (about 151 million gallons/day). (USGS)

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

NASA Astrophysics Data System (ADS)

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.

Uses of diverted methadone and buprenorphine by opioid-addicted individuals in Baltimore, Maryland  

PubMed Central

This study examined the uses of diverted methadone and buprenorphine among opiate-addicted individuals recruited from new admissions to methadone programs and from out-of-treatment individuals recruited from the streets. Self-report data regarding diversion were obtained from surveys and semi-structured qualitative interviews. 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.

GIS-based study on spatial growth of bi-polar with corridor in the Baltimore-Washington region in the USA  

NASA Astrophysics Data System (ADS)

The sprawl process in the metropolitan area of the Baltimore-Washington is a typical Bi-polar growing process among corridors. This paper studies the urbanization of Baltimore-Washington region within 200 years. By using the GIS software Mapinfo7.0, we gained the ratio changes of urbanized area to non-urbanized area and the radii of incircle and circumcircle of two regions. Then we took the former as integrated study and the latter as contrastive study. We find that the metropolitan growth has a 30-40-year cycle phenomenon. Both core growth and corridor growth form the urban expansion of Baltimore and Washington, but each of them has different rates and characteristics. This process can be described as "point-line-net-surface growth model". And the urban growth of Baltimore is better than Washington. Usually, traditional studies of spatial sprawls of Bi-polar of growth with Corridor Structures take the Bi-polar of growth with Corridor Structures as a whole to study the expanding process, while this paper tries to reveal the law of the spatial growth of Bi-polar of growth with Corridor Structures by contrasting the growths of cores, the growths of corridors and the growths of core and corridor in two regions. Moreover, this study is built on the GIS platform and takes the GIS as a research base by using GIS software to access and processing of remote sensing data. At the same time, the paper uses the ecological processes model to carry out quantitative study to deepen its understanding on the Bi-polar growing with corridors structure, and this will conducive to scientific urban and regional planning.

AM, administrative software ease complex Maryland job  

SciTech Connect

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.

Early Cretaceous shelf-edge deltas of the Baltimore Canyon Trough: Principal sources for sediment gravity deposits of the northern Hatteras Basin  

NASA Astrophysics Data System (ADS)

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.

Spent Fuel Transportation Package Response to the Baltimore Tunnel Fire Scenario  

SciTech Connect

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.

Analysis of High Frequency Water Quality Data in the Baltimore Ecosystem Study LTER  

NASA Astrophysics Data System (ADS)

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.

Regional Transport Versus Local Production of Ground Level Tropospheric Ozone in the Baltimore Region: a Statistical Analysis  

NASA Astrophysics Data System (ADS)

Significant levels of ozone in the lowest 2000 m of the atmosphere, often above the planetary boundary layer, have been measured from aircraft flights over the eastern US. These elevated amounts of ozone can be mixed down to the ground as the nocturnal inversion breaks down at about 10.00 am. We have observed this downward insertion of ozone in the daily ground based measurements made by the Maryland Department of the Environment. There is a strong correlation between the amount of ozone brought down and the direction of the winds above the boundary layer, agreeing with previous studies of regional transport. The ozone data from seven measurement sites in the Baltimore region over the period 1994 to 2005 has been examined. There is a distinct change in the amount of ozone mixed down between 2002 and 2003. The implications of the results of the analysis to local pollution controls will be discussed.

Site remediation considerations and foundation excavation plan for the Walter Reed Army Institute of Research building, Forest Glen, Maryland  

SciTech Connect

The US Army Corps of Engineers North Atlantic Division, Baltimore District (CENAB), intends to design and construct a medical and dental research facility for the Walter Reed Army Institute of Research (WRAIR) at the Walter Reed Army Medical Center (WRAMC) at Forest Glen, Maryland. Because almost 100% of the proposed building site is located on an uncontrolled landfill that was thought to possibly contain medical, toxic, radioactive, or hazardous waste, it was assumed that remediation of the site might be necessary prior to or in conjunction with excavation. To assess (1) the need for remediation and (2) the potential hazards to construction workers and the general population, the Baltimore District contracted with Argonne National Laboratory to undertake a site characterization and risk assessment and to develop a foundation-excavation plan. The results of the site characterization and a qualitative risk assessment have been presented in a previous report. This report presents the foundation-excavation plan. 38 refs., 16 figs., 11 tabs.

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

NASA Astrophysics Data System (ADS)

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, ground-level observations and long-term aircraft measurements to characterize trends in air pollution. The USEPA Continuous Emissions Monitoring System (CEMS) program reported substantial decreases in point sources resulting from national and regional control measures; these decreases are definitely reflected in the ground-level observations. The decreasing trend of CO column contents is ~8.0 Dobson Unit (DU) decade-1, corresponding to ~350 ppbv decade-1 in the lower troposphere. Satellite observations of long-term, near-surface CO show ~40% decrease over western Maryland between 2000 and 2011, the same magnitude as indicated by aircraft measurements over upwind regions of Baltimore/Washington aished. After compensating for inter-annual temperature variations, historical aircraft measurements suggest the daily net production of tropospheric ozone over Baltimore/Washington area decreases from ~20 ppbv in the late 1990s to ~7 ppbv in the early 2010s during the ozone season. A decrease in the long-term ozone column content is observed as ~2.0 DU decade-1 in the lowest 1500 m, corresponding to ~13 ppbv decade-1 decrease. Back trajectory cluster analysis demonstrates that emissions of air pollutants from Ohio and Pennsylvania through Maryland influence column contents of downwind ozone in the lower atmosphere. The trends of air pollutants reveal the success of regulations implemented over the last decade and the importance of region wide emission controls over the eastern United States.

Ultrafine nitrate particle events in Baltimore observed by real-time single particle mass spectrometry  

NASA Astrophysics Data System (ADS)

Ambient particles in Baltimore, Maryland were characterized from April through November 2002 using the real-time single particle mass spectrometer, RSMS III. When particles containing nitrate were examined, two types of ultrafine particle events were revealed: a large burst of nominally "pure" nitrate particles in the 50-90 nm size range, and a smaller (and less frequent) burst of "pure" particles in the 50-90 nm size range that grew to 110-220 nm with time. Coincident with both of these events was an increase in the number of mixed composition particles containing nitrate, suggesting that they were formed by condensation of ammonium nitrate onto pre-existing particles. Meteorological variables, particle number concentrations and continuous nitrate mass measurements were compared to the single particle data. Number and mass concentrations estimated from RSMS III correlated well with similar measurements with other techniques. Ultrafine nitrate particle events were observed during periods of low temperature and high relative humidity as expected from ammonium nitrate equilibrium considerations. During these events, the partitioning of ammonium nitrate to the particle phase strongly influenced the particle number concentration as well as the chemical composition.

Deformation sequence of Baltimore gneiss domes, USA, assessed from porphyroblast Foliation Intersection Axes  

NASA Astrophysics Data System (ADS)

The NE-SW trending gneiss domes around Baltimore, Maryland, USA, have been cited as classic examples of mantled gneiss domes formed by diapiric rise of migmatitic gneisses [Eskola, P., 1949. The problem of mantled gneiss domes. Quarterly Journal of Geological Society of London 104/416, 461-476]. However, 3-D analysis of porphyroblast-matrix foliation relations and porphyroblast inclusion trail geometries suggests that they are the result of interference between multiple refolding of an early-formed nappe. A succession of six FIA (Foliation Intersection Axes) sets, based upon relative timing of inclusion texture in garnet and staurolite porphyroblasts, revealed 6 superposed deformation phases. The successions of inclusion trail asymmetries, formed around these FIAs, document the geometry of deformation associated with folding and fabric development during discrete episodes of bulk shortening. Exclusive top to NW shear asymmetries of curvature were recorded by inclusion trails associated with the vertical collapsing event within the oldest FIA set (NE-SW trend). This strongly indicates a large NE-SW-striking, NW-verging nappe had formed early during this deformation sequence. This nappe was later folded into NE-SW-trending up-right folds by coaxial shortening indicated by an almost equal proportion of both inclusion trail asymmetries documented by the second N-S-trending FIA set. These folds were then amplified by later deformation, as the following FIA sets showed an almost equal proportion of both inclusion trail asymmetries.

Body burdens of mercury, lead, selenium and copper among Baltimore newborns  

PubMed Central

Umbilical cord blood or serum concentrations of mercury, lead, selenium and copper were measured with inductively coupled plasma mass spectrometry in a population of 300 infants born Baltimore, Maryland. Geometric mean values were 1.37 ?g/L (95% confidence interval: 1.27, 1.48) for mercury; 0.66 ?g/dL (95% CI: 0.61, 0.71) for lead; and 38.62 ?g/dL (95% CI: 36.73, 40.61) for copper. Mean selenium was 70.10 ?g/L (95% CI: 68.69, 70.52). Mercury, selenium and copper levels were within exposure ranges reported among similar populations, whereas the distribution of lead levels was lower than prior reports; only one infant had a cord blood lead above 10 ?g/dL. Levels of selenium were significantly correlated with concentrations of lead (Spearman’s ? = 0.20) and copper (Spearman’s ? = 0.51). Multivariable analyses identified a number of factors associated with one of more of these exposures. These included: increasing maternal age (increased lead); Asian mothers (increased mercury and lead, decreased selenium and copper); higher umbilical cord serum n-3 fatty acids (increased mercury, selenium and copper), mothers using Medicaid (increased lead); increasing gestational age (increased copper); increasing birthweight (increased selenium); older neighborhood housing stock (increased lead and selenium); and maternal smoking (increased lead). This work provides additional information about contemporary prenatal element exposures and can help identify groups at risk of atypical exposures.

Distributed Watershed Modeling for a Small Urban Basin in Baltimore County, MD  

NASA Astrophysics Data System (ADS)

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 Metropolitan Opera  

NSDL National Science Digital Library

The Metropolitan Opera (or the "Met", as it is known to many) is perhaps the most well-known and beloved opera company in the United States, and possibly, the world. The website is a mirror onto the world of the Met's numerous opera productions, its history, and the overall portrait of this delightful melding of words, emotions, and song. Visitors will want to start by perusing the "Discover Opera" section of the site, where they can read plot synopses of Met productions and also look through a entertaining interactive exhibit that covers the Met's history from 1883 to 2004. Here they will learn when the production of Salome offended polite New York society, and continue on to learn about the tenure of Rudolf Bing. Perhaps the most outstanding feature of the site is the Met Opera Database, which give users access to information on every single performance at the Met since 1883, complete with statistics, photos, and set designs.

The history and nature of the Baltimore applications project  

NASA Technical Reports Server (NTRS)

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.

La Plata, Maryland  

NASA Technical Reports Server (NTRS)

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.

Metropolitan Lima: area profile.  

PubMed

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.

Aftermath of the Great Baltimore Fire of 1904  

NSDL National Science Digital Library

Many American cities were devastated by large fires in the late 19th and early 20th centuries. Baltimore was no exception, and this fine digital collection from the Enoch Pratt Free Library offers publications, photos, and other ephemera related to the Great Baltimore Fire of 1904. The online collection includes over 250 images and 13 publications, including the final report of the Burnt District Commission, along with several initial draft reports. The fire was tragic, as it destroyed over 80 city blocks and hundreds of downtown Baltimore businesses. First-time visitors will want to start their journey here by perusing "The Book of the Fire," which can be found on the homepage. The photos are understandably quite dramatic, and they include images of the "New" Carrolton Hotel in ruins and the Baltimore and Ohio Railroad central headquarters, which escaped the conflagration unscathed due to its fireproof construction. The image viewing software used here is quite good, and visitors can zoom in and out as they see fit. Also, visitors can perform an advanced search if they so wish.

Diet reconstruction in antebellum Baltimore: Insights from dental microwear analysis.  

PubMed

Construction in the City of Baltimore during 1996 led to the recovery of human skeletal remains dating from 1792 to 1856. Historical research indicates that the skeletal remains come from two adjacent graveyards: Christ's Church Episcopalian Cemetery and the Potters Field East. The different socioeconomic status of the internees in each cemetery suggests the possibility of marked contrasts in lifestyle, health, and diet. To shed further light on these possibilities, analyses of microscopic wear patterns on teeth, or dental microwear analyses, were undertaken. A sample from Spanish Florida was used to help interpret the results. Epoxy casts of incisor and molar teeth were placed in an SEM and photomicrographs of clean wear facets were taken. The photomicrographs were digitized using the software package Microware 4.02. Statistical analyses of rank transformed data consisted of single-factor ANOVA, followed by post hoc tests. No significant differences were found between Christ's Church and Potters Field East samples for any of the variables examined in either molar or incisor teeth. However, differences between each Baltimore sample and the La Florida samples give suggestions of possible diet differences in antebellum Baltimore. The mosaic of differences between the Baltimore and La Florida samples probably reflects the wide variety of foods available to antebellum Baltimoreans as well as the relative lack of abrasives in their diet.

Chromatographic, ultracentrifugal, and related studies of fibrinogen "Baltimore"  

PubMed Central

Chromatographic, ultracentrifugal, and related studies of the fibrinogen of a patient with a congenital disorder of fibrinogen (fibrinogen “Baltimore” have provided evidence of structural differences from normal. Diethylaminoethyl-cellulose (DEAE-cellulose) gradient elution chromatography demonstrated two major peaks in the elution pattern of fibrinogen Baltimore as was the case for normal fibrinogen. However, the first peak of fibrinogen Baltimore was somewhat broader and more symmetrical and was eluted significantly later in the chromatogram than the corresponding peak of normal fibrinogen. Additionally, in some elution patterns, a shoulder on the ascending limb of peak 1 was present, suggesting the presence of chromatographically “normal” fibrinogen. Thrombin time determinations of eluted column fractions from a chromatogram of propositus fibrinogen supported this conclusion by demonstrating that fibrinogen from the ascending portion of peak 1 behaved functionally more like normal than that later in the chromatogram. Chromatograms of mixtures of propositus and normal fibrinogen confirmed the ability of this technique to distinguish normal from Baltimore fibrinogen. Chromatograms of fibrinogen isolated from two affected daughters displayed the characteristic increased anionic binding of peak 1 fibrinogen. Sedimentation velocity experiments indicated that the So20, [unk] of fibrinogen Baltimore was slightly greater (8.13S vs. 7.85S) than that of normal fraction I-4. Differences in concentration dependence (- 0.65 c vs. - 1.30 c for normal) of the sedimentation coefficient could be attributable in part to spatial conformational differences. Molecular sieving experiments in acrylamide gels indicated that the molecular weight of propositus fraction I-2 was about the same as that of normal fibrinogen of comparable solubility (i.e. I-4, mol wt 325,000). Studies of the UV spectra, tyrosine/tryptophan ratios, sialic acid and hexose content, and N-terminal amino acids demonstrated no consistent significant differences from normal fraction I-4.

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

NASA Astrophysics Data System (ADS)

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.

Environmental Inequality in Metropolitan America  

PubMed Central

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.

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

USGS Publications Warehouse

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.

HIV Testing Behaviors Among Latinos in Baltimore City  

PubMed Central

In the US, HIV disproportionately affects Latinos who often present late in the disease. Baltimore has seen a recent rapid growth in its Latino population paralleled by an increasing impact of HIV/AIDS among Latinos. From 2009 to 2010, we performed a cross-sectional survey of Latinos accessing the Baltimore City Health Department (BCHD) Latino Outreach services to assess self-report of previous HIV testing, with particular attention to migration history and risk behaviors. Of 247 Latinos (46% male) accessing BCHD outreach services, 96% were foreign-born. Self-perceived HIV risk was not associated with actual risk behaviors or HIV testing. In multivariate models, previous HIV testing was correlated with knowledge of HIV transmission modes and knowing that a person with HIV can appear healthy. Consistent with CDC recommendations, HIV screening among Latino immigrants should not be limited to individuals with self-perceived risk for HIV. Promoting key pieces of HIV knowledge may improve HIV testing behaviors.

Variability in Lower Tropospheric CO2 over the DC/Baltimore Metro Area: Insight for Remote CO2 Sensors  

NASA Astrophysics Data System (ADS)

High-resolution in-situ CO2 measurements were recently recorded onboard the NASA P-3B during the July 2011 DISCOVER-AQ field campaign; a mission designed to investigate the ability of space-based observations to accurately assess near surface conditions relating to air quality. DISCOVER-AQ provided a unique opportunity to examine CO2 distributions over the Baltimore/DC metropolitan region via the execution of a repetitive circuitous flight pattern over six ground measurement sites. The flight route included vertical soundings (0.3 to 4.7 km) over each surface site, and low-level runs (0.3 km) over the Baltimore-Washington Parkway, I-95, and the Chesapeake Bay. In this paper, data from 250 vertical soundings are presented highlighting the remarkable diurnal and spatial variability CO2 exhibits within the lower troposphere, a region of maximum sensitivity for both the GOSAT and OCO remote CO2 sensors. Horizontal gradients in CO2 observed at 0.3 km around each surface site (~ 4 km diameter loop) as well as over the entire flight track are also examined to evaluate the scales of variability influencing GOSAT and OCO footprints (spatial resolutions at nadir of 0.5 km and ~1.29 km × 2.25 km, respectively). These data provide insight into the ability of these space-based observations to fully capture the observed variability given their respective 3 and 16-day ground track repeat cycles and inevitably accurately constrain CO2 surface fluxes. Additionally, we investigate influences on the CO2 distributions using recorded meteorological variables, the HYSPLIT model, in concert with other simultaneously measured trace gases such as acetonitrile and isoprene to explore contributions from biogenic and anthropogenic emissions.

Process Evaluation of Baltimore Healthy Stores: A Pilot Health Intervention Program With Supermarkets and Corner Stores in Baltimore City  

PubMed Central

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.

Immigrants in 2010 Metropolitan America  

NSDL National Science Digital Library

The 2010 Census has afforded scholars and public policy experts with a wealth of data on demographics in the United States, and many people have chosen to use this data to look at urban and suburban settlement patterns. As part of their work at the Brookings Institution's Metropolitan Policy Program Jill H. Wilson and Audrey Singer have composed this 13-page paper which looks at the transformation of the immigrant community over the past decade. Released in October 2011, the report notes that the foreign-born population in the United States reached 40 million in 2010 and that immigrant settlement became less concentrated during the 2000s. The report also notes that 51 percent of immigrants lived in the suburbs of large metropolitan areas, up from 48 percent in 2000. The report also includes several graphs and charts that help provide some visual documentation of these various transformations.

Research and investigation of geology, mineral, and water resources of Maryland  

NASA Technical Reports Server (NTRS)

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.

Final results of the Maryland WIC 5-A-Day Promotion Program.  

PubMed Central

OBJECTIVES: This National Cancer Institute-funded study sought to increase fruit and vegetable consumption among women served by the WIC program in Maryland. METHODS: Over a 2-year period, a multifaceted intervention program using a randomized crossover design sought to increase fruit and vegetable consumption at 16 WIC program sites in Baltimore City and 6 Maryland counties. Participants were surveyed at baseline, 2 months postintervention, and 1 year later. RESULTS: Two months postintervention, mean daily consumption had increased by 0.56 +/- 0.11 servings in intervention participants and 0.13 +/- 0.07 servings in control participants (P = .002). Intervention participants also showed greater changes in stages of change, knowledge, attitudes, and self-efficacy. Changes in consumption were closely related to number of nutrition sessions attended, baseline stage of change, race, and education. One year later, mean consumption had increased by an additional 0.27 servings in both intervention and control participants. CONCLUSIONS: Dietary changes to prevent cancer can be achieved and sustained in this hard-to-reach, low-income population. However, many obstacles must be overcome to achieve such changes.

Determining Boundary Layer Mixing State based on NASA DISCOVER-AQ Airborne Soundings over the Baltimore/Washington Area  

NASA Astrophysics Data System (ADS)

The DISCOVER-AQ (Deriving Information on Surface Conditions from Column and Vertically Resolved Observations Relevant to Air Quality) mission conducted its first field deployment in the Washington D.C./Baltimore region during July 2011. The overarching goal is to better understand how remotely-sensed column measurements can be used to diagnose near-surface air quality. To achieve this objective, the DISCOVER-AQ sampling strategy requires extensive probing of the vertical structure of the lower troposphere as it relates to both trace gases and aerosols. This strategy was implemented by using the NASA P-3B aircraft to spiral from 0.3 to ~3 km over 6 MDE (Maryland Department of the Environment) ground monitoring sites. A total of 254 spirals were flown which generated detailed vertical distributions for a large variety of trace gases, aerosol properties, and meteorological variables. This data set allows a detailed assessment of vertical mixing state, which can be estimated by the changes of the measured variables with height within the boundary layer. The data set was further filtered to minimize the influence of the horizontal inhomogeneity. To be presented are cases under different atmospheric stability classes to show the actual observed atmospheric structure and vertical distributions of the aerosols and trace gases which have a wide range of lifetimes.

Functional evaluation of an inherited abnormal fibrinogen: fibrinogen "Baltimore"  

PubMed Central

The rate of clotting and the rate of development and degree of turbidity after addition of thrombin to plasma or purified fibrinogen from a patient with fibrinogen Baltimore was delayed when compared with normal, especially in the presence of low concentrations of thrombin. Optimal coagulation and development of translucent, rather than opaque, clots occurred at a lower pH with the abnormal fibrinogen than with normal. Development of turbidity during clotting of the abnormal plasma or fibrinogen was less than normal at each pH tested, but was maximal in both at approximately pH 6.4. The physical quality of clots formed from fibrinogen Baltimore was abnormal, as demonstrated by a decreased amplitude on thromboelastography. The morphologic appearance of fibrin strands formed from fibrinogen Baltimore by thrombin at pH 7.4 was abnormal when examined by phase contrast or electron microscopy, but those formed by thrombin at pH 6.4 or by thrombin and calcium chloride were similar to, though less compact, than normal fibrin. The periodicity of fibrin formed from fibrinogen Baltimore was similar to normal and was 231-233 Å. A study of the release of the fibrinopeptides from the patient's fibrinogen and its chromatographic subfractions verified the existence of both a normally behaving and a defective form of fibrinogen in the patient's plasma. The defective form differed from normal in three functionally different ways: (a) the rate of release of fibrinopeptides A and AP was slower than normal; (b) no visible clot formation accompanied either partial or complete release of the fibrinopeptides from the defective form in 0.3 M NaCl at pH 7.4; and (c) the defective component possessed a high proportion of phosphorylated, relative to nonphosphorylated, fibrinopeptide A, while the coagulable component contained very little of the phosphorylated peptide (AP). The high phosphate content of the defective component did not appear to be the cause of the abnormality, but may be the result of an associated metabolic or genetic phenomenon. Images

Fibrinogen Baltimore IV: congenital dysfibrinogenemia with delayed fibrin monomer polymerization.  

PubMed

A congenital dysfibrinogenemia, fibrinogen Baltimore IV, has been found in a 56-year-old Caucasian man. Clinical laboratory studies disclosed a slightly prolonged prothrombin time, but were otherwise unremarkable. Release of fibrinopeptides by thrombin occurs normally, as does ligation of the fibrin polymer by Factor XIII. Approximately half of the isolated fibrin monomers polymerize normally, but the remainder polymerize at about 2% of the initial rate. The functional defect is thus limited to a decrease in the rate of fibrin monomer polymerization. PMID:4002201

The Baltimore and Utrecht models for cluster dissolution  

NASA Astrophysics Data System (ADS)

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.

DISCOVER-AQ observations over the Baltimore-DC area during July 2011  

NASA Astrophysics Data System (ADS)

DISCOVER-AQ is one of five NASA Earth Venture-1 airborne science projects scheduled to occur in the 2011-2015 timeframe. These five-year, targeted science investigations are part of NASA's Earth System Science Pathfinder program. The goal of DISCOVER-AQ is to improve the interpretation of satellite observations to diagnose near-surface conditions relating to air quality. Distinguishing between pollution at the surface and aloft is a particularly difficult problem for satellites. The strategy for studying this problem is articulated in the acronym which stands for Deriving Information on Surface conditions from COlumn and VERtically resolved observations relevant to Air Quality. This strategy dictates an observational approach that enables systematic and concurrent observation of column-integrated, surface, and vertically-resolved distributions of aerosols and trace gases relevant to air quality as they evolve throughout the day. This was accomplished over the Baltimore-Washington area during July 2011 as the project completed the first of four planned deployments. Two NASA aircraft were flown over six instrumented ground sites on fourteen days. The NASA UC-12 flew a circuit at high altitude (26 kft) passing over individual ground sites five to six times on each flight day, providing lidar observations of aerosols and passive remote sensing of trace gases. Concurrently, the NASA P-3B conducted in situ sampling of trace gases and aerosols along a circuit that allowed for three profiles of the lower atmosphere over each ground site (typically from 10,500 to 1000 feet) as well as low altitude transects along the I-95 corridor at 1000 feet. The six ground sites were chosen from the long-term monitoring network maintained and operated by the Maryland Department of the Environment. These sites also hosted additional instrumentation that included remote sensors (sunphotometers and trace gas spectrometers), instrumented trailers, ozonesondes, and tethered balloons. Partners also contributed additional airborne observations, ground lidars, ship-based measurements over the Chesapeake Bay, and satellite observations. This presentation will provide details on the scope and breadth of measurements and the extensive contributions from DISCOVER-AQ investigators and partners. Selected data and preliminary findings will be presented as well as an introduction to the data archive which is open to anyone interested in using the data for their own research.

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

USGS Publications Warehouse

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

Print by Print: The Baltimore Museum of Art  

NSDL National Science Digital Library

The Baltimore Museum of Art presents this online exhibition, which amounts to a handy study guide on printmaking, and covers both common topics treated in prints, and the technology of printmaking. The exhibit compares the work of two pairs of printmakers, Albrecht Durer and Odilon Redon, and William Hogarth and Andrew Raftery. The two pairs are separated by wide spans of time and distance - Durer worked in Germany in the 15th century, while Redon worked in 19th century France. William Hogarth is best known for his satirical depictions of urban life in England in the 18th century, while Andrew Raftery portrays 20th and 21st century American life. Redon and Durer's visions of apocalypse are compared here, as are Hogarth's series A Harlot's Progress, 1732, and Raftery's Open House, Five Engraved Scenes, 2008. Two additional sections explore contemporary printmaking, adding the work of six more artists to Raftery's and explaining printmaking techniques.

For this study, SIPM was applied to create a Base Case, 15-year (1981-1995) simulation of the DMOC for the Essex site in Baltimore, MD. The Base Case was used as part of a sensitivity analysis that examined the changes in the DMOC due to prescribed NO x and VOC point and area source emission changes. It was noted that decreasing point or area source NO x emissions up to 75% increased the number of 1-h exceedances relative to that found in the Base Case, and that decreasing total anthropogenic VOC emissions by as little as 6% decreased the number of 1-h exceedances by almost 50%.

Understanding expanded school mental health services in Baltimore City.  

PubMed

This article explores the nature of expanded school mental health (ESMH) services in Baltimore City, which at the time of the study were incorporated into 40% of the city's public schools. A provider survey was distributed to ESMH clinicians to gather information on the characteristics of service providers and recipients, types of services being provided, and their proposed outcomes. Provider reports indicated an impressive service capacity, augmentation of traditional school-based services, and the continual need for increased mental health service hours in their buildings. In addition, the most frequently voiced benefits of the ESMH programs were increased mental health awareness and improved school climate. Implications of the findings for future programming development and research are discussed. PMID:15186511

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

NASA Astrophysics Data System (ADS)

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.

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

NASA Astrophysics Data System (ADS)

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.

Metropolitan Police Service: Crime Mapping  

NSDL National Science Digital Library

Over the past several years, more and more big-city police departments have been able to join crime data with sophisticated geographic-information systems to offer a more detailed portrait of crime patterns for the general public's edification. Recently, the Metropolitan Police of London decided to engage in just such an initiative, and this website contains the helpful results of their concentrated labor. The site is graphics-intensive, but it remains easy to use. Users can use the "Find your area" to browse around by postcode or even select different boroughs from a drop down list. Visitors can zoom in and out as they see fit, and they will also want to consult the detailed key which offers some relative perspective on the various levels of crime throughout the different areas of the city. Overall, it's a very fine resource for aspiring criminologists, students of human behavior, and those who are just interested in London.

The Geography of Metropolitan Carbon Footprints  

SciTech Connect

The world s metropolitan carbon footprints have distinct geographies that are not well understood or recognized in debates about climate change, partly because data on greenhouse gas emissions is so inadequate. This article describes the results of the most comprehensive assessment of carbon footprints for major American metropolitan areasavailable to date, focusing on residential and transportation carbon emissions for the largest 100 metropolitan areas in the United States. These findings are put into the context of effortsacross the country and the globe to characterize carbon impacts and policy linkages.

Satellite exchange in the Baltimore Needle Exchange Program.  

PubMed Central

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

Cation Chemistry in Baltimore Streams: Another Syndrome Symptom?  

NASA Astrophysics Data System (ADS)

Urban streams are degraded due to a variety of physical and chemical factors including impervious surfaces, sewer cross-connections, and multiple chemical contaminants. There is particular interest in the loading of anionic nutrients and heavy metals into urban streams, especially those draining to nutrient sensitive receiving waters. However, there has been less characterization of cation chemistry in urban streams. We examined metal concentrations in archived water samples as part of the stream monitoring program of the Baltimore Ecosystem Study (BES), an urban component of the U.S. National Science Foundation Long Term Ecological Research network. Preliminary analysis suggests sewer cross-connections (storm and sanitary) influence metal concentrations (e.g. Si, Ca, Mg). For example, while silica content is elevated in water draining BES agricultural watersheds, it is also elevated in watersheds with extensive impervious surface coverage, areas with the least water-rock interaction. These results raise questions about the effects of urbanization on chemical weathering, the stoichiometry of urban storm and sewer waters, and the potential for human inputs to function as hydrologic tracers in urban watersheds.

Metals in Baltimore Riparian Sediments: Chemical Legacies in Urban Streams  

NASA Astrophysics Data System (ADS)

Riparian sediments are hot zones of biogeochemical activity, particularly nutrient processing. This has lead to their prominent role in national nutrient management strategies. However, while chemical nutrient processing in these systems is relatively well characterized, our understanding of other geochemical interactions in these zones remains limited, particularly in areas with significant trace metal contamination (e.g., urban and suburban systems). Patterns in trace metal concentrations in riparian sediment profiles from a longitudinal transect along the Gwynns Falls and its tributaries will be presented. This watershed is part of the Baltimore Ecosystem Study, a Long-Term Ecological Research Site. While concentrations of many metals decrease in the urbanized portion of the basin, several metal concentrations increase with urbanization (e.g., Pb, Zn, and Ca concentrations all increase 2-5 times in surface sediments when from rural/suburban to urban land use). We will focus on the relationships between metal concentrations, urbanization gradients, land use history, and local physiography to identify urban processes controlling these metal concentration patterns. Moreover this information may be use to assess potential risk of mobilization to surface water systems, particularly via interaction with organic carbon species.

Whole grain intake: The Baltimore Longitudinal Study of Aging  

PubMed Central

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.

It is regrettably decades too late to hear Ezio Pinza sing "Deh, vieni alla finestra" live from the Metropolitan Opera or Caruso offer his splendid version of "Questa o quello" from Verdi's Rigoletto, but these lovely recordings are alive again on the Met's very enchanting Met Archives website. First-time visitors may wish to read over the introductory essay on the history of the Met, and then proceed to the interactive timeline, "Sights & Sounds of Met History". As mentioned, there are many wonderful audio excerpts available within the "Sounds of the Met"section, and the Met Opera Database allows visitors to search for information on various productions throughout the Met's past. Here you can learn a great deal, including that La Boheme has been performed a total of 1178 times at the Met, while Die Lustigen Weiber Von Windsor by Nicolai-Mosenthal has been performed only once there. Additionally, users can peruse the "Stories of the Operas" area to read brief summaries of such works as Cosi fan tutte, Lulu, and Gotterdammerung.

The character of single particle sulfate in Baltimore  

NASA Astrophysics Data System (ADS)

A major component of PM 2.5 in urban aerosol in the eastern United States is sulfate. The eastern US is heavily influenced by regional sources (e.g. coal combustion in the Ohio River Valley) and also by local sources. From March to December 2002, the Baltimore aerosol was characterized with the real-time single-particle mass spectrometer RSMS III. RSMS III is capable of simultaneous positive/negative ion detection of size selected particles between 45 and 1250 nm in diameter. The negative ion detection ability allows sulfate to be monitored. Particles were first sorted into two groups based on the negative ion spectra: (1) those with sulfate detected and (2) those with no sulfate detected. The two groups were further sub-divided by ART 2-a analysis of the positive ion spectra to determine which particle compositions are most/least likely to contain detectable sulfate. A separate analysis was also performed on the positive ion spectra to determine the presence/absence of specific metals in the group of particles with and without sulfate. The correlation of positive and negative ion spectra in this manner allows particle types that are strongly associated with sulfate to be distinguished from those which are not. Particle types strongly correlated with sulfate are nitrate, organic carbon/nitrate (OCAN) and vanadium. Particle types weakly associated with sulfate include carbon and potassium/sodium. Many particles contain both sulfate and nitrate, which suggests that they are acid neutralized. While laser ablation mass spectrometry has inherent limitations for particulate sulfate detection, the results presented here suggest that sulfate detection by this method is a reasonable indicator of particle source and atmospheric transformation.

Receptor modeling for multiple time resolved species: The Baltimore supersite  

NASA Astrophysics Data System (ADS)

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

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)

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.

Stratigraphic framework and petroleum potential of Northeastern Baltimore Canyon Trough, Mid-Atlantic Outer Continental Shelf  

SciTech Connect

Geologic data from 29 wells in the Baltimore Canyon Trough were released to the public as of 1982, and provide sufficient information for establishing Upper Jurassic through Cenozoic rock-stratigraphic units. The oldest rocks penetrated by exploratory wells are of Late Jurassic age and are correlative to the Scotian Shelf Mohawk, Mic Mac, and Abenaki Formations. The Mohawk(.) sandstone and Mic Mac shale equivalents in the Baltimore Canyon Trough represent lower delta plain to predominantly prodelta environments, and the Abenaki-equivalent limestone represents a shelfmargin carbonate buildup. A destructional phase of the delta is represented by the Naskapi equivalents a calcareous shale. Stratigraphic traps may be present in the Baltimore Canyon Trough Upper Jurassic and Lower Cretaceous deltaic sandstones and shelf-margin carbonates. The deltaic units contain channel and distributary-mouth-bar sandstones, which may be potential reservoirs. The Abenaki stratigraphic-reef trend provides another potential target.

Fibrinogen Baltimore IV: congenital dysfibrinogenemia with a gamma 275 (Arg----Cys) substitution.  

PubMed

The major functional characteristics of fibrinogen Baltimore IV include delayed fibrin monomer polymerization which is not corrected by the addition of calcium, inhibition of normal plasma coagulation upon mixing, and a biphasic polymerization profile in which the abnormal fibrin monomers appear to polymerize at about 2% of the normal rate (Ebert & Bell, Thromb. Res. 38:121-128, 1985). We now report the detection of an abnormal peptide in a comparative peptide map from a cyanogen bromide digest of fibrinogen Baltimore IV. The sequence of this peptide corresponds to the fibrinogen sequence gamma 265-310, except that Arg275 is replaced by Cys. Amino acid analyses of carboxymethylated peptides from control vs. fibrinogen Baltimore IV confirmed the sequencing data. Both the propositus and his affected daughter were heterozygous for the trait. PMID:2617471

Stratigraphic framework and petroleum potential of northeastern Baltimore Canyon Trough, mid-Atlantic outer Continental Shelf  

SciTech Connect

Geologic data from 29 wells in the Baltimore Canyon Trough were released to the public as of 1982, and provide sufficient information for establishing Upper Jurasic through Cenozoic rock-stratigraphic units. Most of the units are lithologically similar to formations on the Scotian Shelf and are, therefore, considered in this study to be the Scotian Shelf homotaxial equivalents. The Mohawk(.) sandstone and Mic Mac shale equivalents in the Baltimore Canyon Trough represent lower delta plain to predominantly prodelta environments, and the Abenaki-equivalent limestone represents a shelf margin carbonate buildup. Inundation by the sea was incomplete, however, and channel and distributary-mouth-bar sands (Logan Canyon equivalent) were deposited. A final marine transgression began during the Late Cretaceous and resulted in the deposition of mudstone, which is considered equivalent to the Scotian Shelf Dawson Canyon Formation. Although both basins exhibit an upward increase in sand content, the Scotian Shelf Cenozoic strata are more sandy than those in the Baltimore Canyon Trough. Stratigraphic traps may be present in the Baltimore Canyon Trough Upper Jurassic and Lower Cretaceous deltaic sandstones and shelf-margin carbonates. The deltaic units contain channel and distributary-mount-bar sandstones, which may be potential reservoirs. Seals may be formed by lateral and vertical contacts against the prodelta, interdistributary bay, and marine shales. The Abenaki stratigraphic-reef trend provides another potential target. Source rocks, reservoir rocks, and traps may be associated with the trend, but its potential can only be defined by future drilling. 16 figures, 2 tables.

Baltimore WATERS Test Bed -- Quantifying Groundwater in Urban Areas  

NASA Astrophysics Data System (ADS)

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.

The University of Maryland Medical System invests in its community's minorities.  

PubMed

As a private, non-state-owned teaching hospital adjacent to a predominately low income African American community in Baltimore, the University of Maryland Medical System (hereafter called the Medical System) in partnership with the state's medical school has historically provided excellent medical care to the community's residents regardless of their ability to pay. Nevertheless, executive leadership recognized that the Medical System needed to be even more socially and economically responsible to the minority community by investing more of the system's resources in that community. Doing so would improve the economic strength of the community, and this strength would help the Medical System to continue to thrive and expand its business in Baltimore City. Therefore, in the late 1980s, the Medical System created a program that focuses on greater inclusion of minorities particularly African Americans, in personnel, construction, purchasing, and community outreach. In the area of personnel, recruitment efforts have focused on increasing the representation of minorities, particularly African Americans, in management and residency positions. The result has been the creation of a more supportive environment for minority personnel throughout the organization as well as for minority patients and vendors who have dealings with the medical system. In the area of construction, minority development efforts have included the establishment of a flexible bid-award policy and a partnership with the minority business community. As a result, total construction dollars spent with minority-owned firms increased from $2 million to $18 million over seven years, and the portion of these dollars spent with African American-owned firms increased sixfold. In the area of purchased goods and services, more creative approaches to improving minority participation have been necessary. These have included partnering minority distributors with major suppliers and literally assisting in the creation of new minority firms capable of effectively responding to the competitive marketplace. As a result, purchasing dollars spent with minority-owned firms increased from $1.5 million to $3.2 million in four years, and the portion of these dollars spent with African American-owned firms nearly tripled. In community outreach, a comprehensive program has emerged that includes education, career development, disease prevention, and health promotion activities. The Medical System has encountered many barriers to success in these efforts but fortunately has overcome many of them. This article outlines the methods the system has used to achieve its minority development goals, with particular emphasis on the difficult area of purchasing. PMID:9125916

Education, Demand, and Unemployment in Metropolitan America  

NSDL National Science Digital Library

What's the biggest challenge facing urban areas these days? Some might say problems with infrastructure, and others might say a lack of adequately trained employees. This paper from September 2011 by staff members at the Brookings Institution takes a close look into the world of economic recovery in metropolitan areas in the United States. Specifically, the work examines the problems involving public investment in education and how "structural unemployment" will continue to hinder the economic recovery in certain metropolitan areas. The paper begins with a series of short "Findings", which can be read as a type of policy brief for those with limited time. The report also contains a set of graphs and methodological appendices for those who might have a particular interest in their research methods and statistical work.

Maryland striped bass: recruitment declining below replacement  

SciTech Connect

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.

The Geographic Scale of Metropolitan Racial Segregation  

PubMed Central

This article addresses an aspect of racial residential segregation that has been largely ignored in prior work: the issue of geographic scale. In some metropolitan areas, racial groups are segregated over large regions, with predominately white regions, predominately black regions, and so on, whereas in other areas, the separation of racial groups occurs over much shorter distances. Here we develop an approach—featuring the segregation profile and the corresponding macro/micro segregation ratio—that offers a scale-sensitive alternative to standard methodological practice for describing segregation. Using this approach, we measure and describe the geographic scale of racial segregation in the 40 largest U.S. metropolitan areas in 2000. We find considerable heterogeneity in the geographic scale of segregation patterns across both metropolitan areas and racial groups, a heterogeneity that is not evident using conventional “aspatial” segregation measures. Moreover, because the geographic scale of segregation is only modestly correlated with the level of segregation in our sample, we argue that geographic scale represents a distinct dimension of residential segregation. We conclude with a brief discussion of the implications of our findings for investigating the patterns, causes, and consequences of residential segregation at different geographic scales.

Forecasted electric power demands for the Baltimore Gas and Electric Company. Volume 1 and Volume 2. Documentation manual  

SciTech Connect

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

Social geographies of African American men who have sex with men (MSM): a qualitative exploration of the social, spatial and temporal context of HIV risk in Baltimore, Maryland.  

PubMed

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.

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

PubMed Central

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.

The University of Maryland Electron Ring Program  

NASA Astrophysics Data System (ADS)

The University of Maryland Electron Ring (UMER) is a unique machine that uses scaled electron beams at nonrelativistic energies (10 keV) to inexpensively model GeV beams of heavy ions over long path lengths (kilometers of transport distance). The UMER beam parameters correspond to space charge tune depressions, at injection, adjustable in the range of 0.14-0.85. Although a ring, many of the intense beam studies on UMER are applicable to linacs. This paper reviews the UMER program, which contains experimental, computational, and theoretical components. We outline the research areas of interest, recent accomplishments, and future plans, emphasizing the relevance to heavy ion drivers. Specific topics include longitudinal induction focusing and beam manipulations; generation and propagation of space charge waves, including large-amplitude solitons; bunch end interpenetration and observation of a multi-stream instability; beam halo studies; and diagnostic development.

The 1998 Baltimore Particulate Matter Epidemiology-Exposure Study: part 1. Comparison of ambient, residential outdoor, indoor and apartment particulate matter monitoring.  

PubMed

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

Mosquitoes (Diptera: Culicidae) of metropolitan Hamburg, Germany.  

PubMed

In Europe, mosquito-related public health concerns are growing due to the increasing spread of invasive mosquito species and the recent emergence of mosquito-borne arboviruses. A vital backbone in the assessment of these issues is detailed knowledge of the mosquito fauna, i.e. regional mosquito inventories. It was therefore decided to intensify nationwide investigations on the occurrence and distribution of mosquitoes in Germany in order to update old records and to detect possible faunal changes. This paper is focussing on a densely populated metropolitan region, the federal state of Hamburg and its adjacent environs, taking two historical baseline inventories into consideration, spanning almost 100 years of mosquito research in Hamburg. In the period between 2010 and 2014, more than 10,000 juvenile, neonate and adult mosquito specimens were sampled and trapped at 105 sites in Hamburg and its environs, of which about 60 % have been identified to species level, resulting in a total of 33 recorded species. Of these, Anopheles algeriensis, Culex modestus, Ochlerotatus caspius, Ochlerotatus nigrinus and Ochlerotatus sticticus are new to the area. The most common species in Hamburg are Culex pipiens/torrentium and Ochlerotatus annulipes/cantans. In contrast, two previously common species, Anopheles atroparvus and Ochlerotatus excrucians, were not detected. Despite substantial environmental changes due to reconstruction, urbanisation and renaturation in the Hamburg metropolitan region in recent decades, there has been remarkably little change within the mosquito fauna during the last century.

Cigarette sales to African-American and white minors in low-income areas of Baltimore.  

PubMed Central

OBJECTIVES: This study documented illegal sales of cigarettes to minors in low-income African-American and White urban areas in East Baltimore. METHODS: Six youths, aged 14 through 16 years, were sent to a random sample of 83 corner stores to attempt to purchase cigarettes. The youths provided the investigators with data on merchant, store, and purchase characteristics. RESULTS: The youths successfully purchased cigarettes in 85.5% of the stores; 58% of the stores displayed five or more cigarette advertisements outside their premises. CONCLUSIONS: Cigarette sales to minors and associated advertising remain prevalent in this urban community.

Individual particle analysis of indoor, outdoor, and community samples from the 1998 Baltimore particulate matter study  

NASA Astrophysics Data System (ADS)

The United States Environmental Protection Agency (US EPA) recently conducted the 1998 Baltimore Particulate Matter (PM) Epidemiology-Exposure Study of the Elderly. The primary goal of that study was to establish the relationship between outdoor PM concentrations and actual human PM exposures within a susceptible (elderly) sub-population. Personal, indoor, and outdoor sampling of particulate matter was conducted at a retirement center in the Towson area of northern Baltimore County. Concurrent sampling was conducted at a central community site. The main objective of this work was to use computer-controlled scanning electron microscopy (CCSEM) with individual-particle X-ray analysis to measure the chemical and physical characteristics of geological and trace element particles collected at the various sampling locations in and around the retirement facility. The CCSEM results show that the relative abundances of some geological and trace element particle classes identified at the outdoor and community locations differ from each other and from the indoor location. Particle images acquired during the computer-controlled analyses played a key role in the identification of certain particle types. Review of these images was particularly useful in distinguishing spherical particles (usually indicative of combustion) from non-spherical particles of similar chemical composition. Pollens and spores were also identified through a manual review of the particle images.

Petroleum geology of the Upper Jurassic and Lower Cretaceous, Baltimore Canyon trough, western North Atlantic Ocean  

SciTech Connect

Numerous hydrocarbon shows, including a noncommercial gas and gas-condensate accumulation, occur in the Baltimore Canyon Trough within sandstone units deposited in prograding coastal-plain and transitional-marine environments located updip of an Oxfordian/Kimmeridgian carbonate shelf edge. The coastal-plain and transitional-marine facies are overlain by a fine-grained deltaic complex dominated by delta-plain shales which collectively form a regionally extensive top seal unit. Wells drilled seaward of the continental shelf edge ( > 1,500 m water depth) tested large structural/stratigraphic closures along the downdip termination of the Upper Jurassic/Lower Cretaceous carbonate shelf edge but encountered no significant hydrocarbon shows. Reservoir rocks in these wells consist of (1) oolite grain-stone, which was deposited within a shoal-water complex located at the Aptian shelf edge, and (2) coral-stromatoporoid grainstone and boundstone. Structural closures having reservoir and top seals are present in both updip and downdip trends. hydrocarbon shows in wells along the shelf interior trend indicate the presence of mature source beds, at least locally. The absence of hydrocarbon shows in downdip carbonate reservoirs and around the Schlee Dome, however, suggests charge/migration mechanisms within the fetch areas of these objectives have failed. Continued development of play concepts in the Baltimore Canyon Trough, therefore, requires identification and mapping of potential source-rock intervals and construction of hydrocarbon expulsion models to time hydrocarbon generation relative to trap formation.

How Metropolitan Areas Can Lead National Export Growth  

NSDL National Science Digital Library

Economists and others realize the tremendous value of metropolitan areas, and recently the Brookings Institution took a close look at this subject in this compelling piece of research. In this 46-page report released in July 2010, three scholars at the Institution (Emilia Istrate, Jonathan Rothwell, and Bruce Katz) took a close look at potential export growth throughout America's metropolitan region. The work notes that metropolitan areas currently product 84 percent of the nation's exports and the 100 largest metropolitan areas alone account for over 64 percent of the nation's exports. The report starts with a basic overview of their findings, and it also includes an executive summary. On the site, visitors can also watch videos of the researchers talking about the work, and its potential policy implications.

Effects of environmental pollutants on Connecticut and Maryland ospreys  

USGS Publications Warehouse

Osprey (Pandion haliaetus) eggs were exchanged between Connecticut and Maryland osprey nests in 1968 and 1969 to test the hypothesis that the decline in reproductive success of Connecticut ospreys was caused by something within the external environment of the eggs. Incubation of 30 Connecticut osprey eggs by Maryland ospreys did not improve the hatching rate. Forty-five Maryland osprey eggs incubated by Connecticut ospreys hatched at their normal rate. The results of the egg exchanges and associated observations indicated that the most probable cause of the poor reproduction of Connecticut ospreys ,was related to contamination of the birds and their eggs. Residues of DDT and its metabolites, dieldrin, and PCBs were generally higher in fish from Connecticut than from Maryland. During 1968-69, average residues (on a nest basis) in osprey eggs from Maryland were: p,p'-DDE, 2.4 ppm; dieldrin, 0.25 ppm; PCB, 2.6 ppm. Average residues in eggs from Connecticut for the same period were: p,p'DDE, 8.9 ppm; dieldrin, 0.61 ppm; PCB, 15 ppm. There were no major changes in residue content of Connecticut eggs collected in 1964 compared with those collected in 1968-B9. One Connecticut osprey had a concentration of dieldrin in its brain which was in the lethal range. The average shell thickness of recently collected osprey eggs from Connecticut had declined 18 percent, and those from Maryland had declined 10 percent from pre-1947 norms. Dieldrin, DDE, and PCB are three environmental pollutants that have most likely been important factors in the greatly reduced reproductive success and rapid population decline of Connecticut ospreys.

Understanding metropolitan patterns of daily encounters  

PubMed Central

Understanding of the mechanisms driving our daily face-to-face encounters is still limited; the field lacks large-scale datasets describing both individual behaviors and their collective interactions. However, here, with the help of travel smart card data, we uncover such encounter mechanisms and structures by constructing a time-resolved in-vehicle social encounter network on public buses in a city (about 5 million residents). Using a population scale dataset, we find physical encounters display reproducible temporal patterns, indicating that repeated encounters are regular and identical. On an individual scale, we find that collective regularities dominate distinct encounters’ bounded nature. An individual’s encounter capability is rooted in his/her daily behavioral regularity, explaining the emergence of “familiar strangers” in daily life. Strikingly, we find individuals with repeated encounters are not grouped into small communities, but become strongly connected over time, resulting in a large, but imperceptible, small-world contact network or “structure of co-presence” across the whole metropolitan area. Revealing the encounter pattern and identifying this large-scale contact network are crucial to understanding the dynamics in patterns of social acquaintances, collective human behaviors, and—particularly—disclosing the impact of human behavior on various diffusion/spreading processes.

Ground-water quality and discharge to Chincoteague and Sinepuxent Bays adjacent to Assateague Island National Seashore, Maryland  

USGS Publications Warehouse

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.

Volunteering: A Physical Activity Intervention for Older Adults--The Experience Corps® Program in Baltimore  

PubMed Central

There is compelling evidence supporting the benefits of increased regular physical activity in older adults. The Experience Corps program in Baltimore MD was designed in part as a community based approach to increasing physical activity that would also appeal to older adults who have historically not utilized health promotion programs. The Baltimore Experience Corps program places older volunteers in public elementary schools for 15 h a week in roles designed to improve the academic outcomes of children and, simultaneously, increase the physical, cognitive and social activity of volunteers. This paper reports on the change in physical activity levels among older adults associated with participation in the Baltimore Experience Corps. In a pilot randomized controlled evaluation, older adults were randomly assigned to Experience Corps (EC participants) or a waiting list control group. Ages ranged from 59–86 years, 96% were African American, 94% were women, and 84% had annual incomes less than $15,000. EC participants were required to serve ?15 h a week. At follow-up after 4–8 months, an analysis of 113 randomized volunteers revealed 53% of the EC participants were more active than the previous year by self-report, as compared to 23% of the controls (p<0.01). When adjusted for age, gender and education, there was a trend toward increased physical activity in the EC participants as calculated by a kilocalorie per week increase of 40%, versus a 16% decrease in the controls (p=0.49). EC participants who reported “low activity” at baseline experienced an average 110% increase in their physical activity at follow-up. Among the controls who were in the “low activity” group at baseline, there was, on average, only a 12% increase in physical activity (p=0.03). Among those who were previously active, there was no significant difference (p=0.30). The pilot results suggest that a high intensity volunteer program that is designed as a health promotion intervention can lead, in the short-term, to significant improvements in the level of physical activity of previously inactive older adult volunteers.
