    2009-01-01

    From 1998 through 2007, over 750 surface-water or bed-sediment samples in the Blue River Basin - a largely urban basin in metropolitan Kansas City - were analyzed for more than 100 anthropogenic compounds. Compounds analyzed included nutrients, fecal-indicator bacteria, suspended sediment, pharmaceuticals and personal care products. Non-point source runoff, hydrologic alterations, and numerous waste-water discharge points resulted in the routine detection of complex mixtures of anthropogenic compounds in samples from basin stream sites. Temporal and spatial variations in concentrations and loads of nutrients, pharmaceuticals, and organic wastewater compounds were observed, primarily related to a site's proximity to point-source discharges and stream-flow dynamics. ?? 2009 ASCE.

    To quantify the percentage of patients counseled by community-based pharmacists. Phase I consisted of a 15-minute observational period of pharmacist counseling in 50 randomly selected pharmacies in the Kansas City, MO, area. In phase II, a survey was mailed to the same pharmacies to obtain policies, self-reported rates of counseling, baseline workload, and personnel information, as well as perceived communication barriers. Forty-six of 50 pharmacies were observed in phase I after excluding 10 ineligible pharmacies and adding 6 replacement pharmacies. Pharmacists provided counseling in only 14 of the 46 pharmacies (30%). Nineteen percent (20/106) of all patients received pharmacist-initiated counseling. Pharmacists in independent pharmacies were observed counseling a significantly higher percentage of patients than were pharmacists in chain pharmacies (44% vs. 11%; p = 0.014). Technicians were observed counseling 5 patients in chain pharmacies. Detailed verbal counseling, defined as four or more of a group of major counseling components, was provided to only 8 of the 20 patients who were counseled by a pharmacist (40%; 8% of all patients). In phase II, 31 of 51 surveys (61%) were returned. During the requested survey time period, pharmacies estimated that approximately five prescriptions were filled every 15 minutes, 51.5% of which were new. Pharmacists in chain pharmacies reported dispensing greater numbers of prescriptions than did pharmacists in independent pharmacies. These data and the reported counseling rates indicated that 50% of all patient prescriptions should be counseled. This is a higher rate than actually observed. All pharmacies reported that pharmacists completed the counseling; however, 10% of the respondents reported that technicians also counseled patients. Contrary to the findings in phase I, slightly more than 50% of the pharmacists reported using detailed verbal counseling. The overall observed rate of counseling in community pharmacies is low

    Macroinvertebrates were collected as part of two separate urban water-quality studies from adjacent basins, the Blue River Basin (Kansas City, Missouri), the Little Blue River and Rock Creek Basins (Independence, Missouri), and their tributaries. Consistent collection and processing procedures between the studies allowed for statistical comparisons. Seven Blue River Basin sites, nine Little Blue River Basin sites, including Rock Creek, and two rural sites representative of Missouri ecological drainage units and the area’s ecoregions were used in the analysis. Different factors or levels of urban intensity may affect the basins and macroinvertebrate community metrics differently, even though both basins are substantially developed above their downstream streamgages (Blue River, 65 percent; Little Blue River, 52 percent). The Blue River has no flood control reservoirs and receives wastewater effluent and stormflow from a combined sewer system. The Little Blue River has flood control reservoirs, receives no wastewater effluent, and has a separate stormwater sewer system. Analysis of macroinvertebrate community structure with pollution-tolerance metrics and water-quality parameters indicated differences between the Blue River Basin and the Little Blue River Basin.

    This is the first part of a study that evaluates the influence of nonpoint-source contaminants on the sediment quality of five streams within the metropolitan Kansas City area, central United States. Surficial sediment was collected in 2003 from 29 sites along five streams with watersheds that extend from the core of the metropolitan area to its development fringe. Sediment was analyzed for 16 polycyclic aromatic hydrocarbons (PAHs), 3 common polychlorinated biphenyl mixtures (Aroclors), and 25 pesticide-related compounds of eight chemical classes. Multiple PAHs were detected at more than 50% of the sites, and concentrations of total PAHs ranged from 290 to 82,150 ??g/kg (dry weight). The concentration and frequency of detection of PAHs increased with increasing urbanization of the residential watersheds. Four- and five-ring PAH compounds predominated the PAH composition (73-100%), especially fluoranthene and pyrene. The PAH composition profiles along with the diagnostic isomer ratios [e.g., anthracene/(anthracene + phenanthrene), 0.16 ?? 0.03; fluoranthene/(fluoranthene + pyrene), 0.55 ?? 0.01)] indicate that pyrogenic sources (i.e., coal-tar-related operations or materials and traffic-related particles) may be common PAH contributors to these residential streams. Historical-use organochlorine insecticides and their degradates dominated the occurrences of pesticide-related compounds, with chlordane and dieldrin detected in over or nearly 50% of the samples. The occurrence of these historical organic compounds was associated with past urban applications, which may continue to be nonpoint sources replenishing local streams. Concentrations of low molecular weight (LMW; two or three rings) and high molecular weight (HMW; four to six rings) PAHs covaried along individual streams but showed dissimilar distribution patterns between the streams, while the historical pesticide-related compounds generally increased in concentration downstream. Correlations were noted

  5. Character and Trends of Water Quality in the Blue River Basin, Kansas City Metropolitan Area, Missouri and Kansas, 1998 through 2007

    2009-01-01

    Water-quality and ecological character and trends in the metropolitan Blue River Basin were evaluated from 1998 through 2007 to provide spatial and temporal resolution to factors that affect the quality of water and biota in the basin and provide a basis for assessing the efficacy of long-term combined sewer control and basin management plans. Assessments included measurements of stream discharge, pH, dissolved oxygen, specific conductance, turbidity, nutrients (dissolved and total nitrogen and phosphorus species), fecal-indicator bacteria (Escherichia coli and fecal coliform), suspended sediment, organic wastewater and pharmaceutical compounds, and sources of these compounds as well as the quality of stream biota in the basin. Because of the nature and myriad of factors that affect basin water quality, multiple strategies are needed to decrease constituent loads in streams. Strategies designed to decrease or eliminate combined sewer overflows (CSOs) would substantially reduce the annual loads of nutrients and fecal-indicator bacteria in Brush Creek, but have little effect on Blue River loadings. Nonpoint source reductions to Brush Creek could potentially have an equivalent, if not greater, effect on water quality than would CSO reductions. Nonpoint source reductions could also substantially decrease annual nutrient and bacteria loadings to the Blue River and Indian Creek. Methods designed to decrease nutrient loads originating from Blue River and Indian Creek wastewater treatment plants (WWTPs) could substantially reduce the overall nutrient load in these streams. For the main stem of the Blue River and Indian Creek, primary sources of nutrients were nonpoint source runoff and WWTPs discharges; however, the relative contribution of each source varied depending on how wet or dry the year was and the number of upstream WWTPs. On Brush Creek, approximately two-thirds of the nutrients originated from nonpoint sources and the remainder from CSOs. Nutrient assimilation

    This is the second part of a study that evaluates the influence of nonpoint sources on the sediment quality of five adjacent streams within the metropolitan Kansas City area, central United States. Physical, chemical, and toxicity data (Hyalella azteca 28-day whole-sediment toxicity test) for 29 samples collected in 2003 were used for this evaluation, and the potential causes for the toxic effects were explored. The sediments exhibited a low to moderate toxicity, with five samples identified as toxic to H. azteca. Metals did not likely cause the toxicity based on low concentrations of metals in the pore water and elevated concentrations of acid volatile sulfide in the sediments. Although individual polycyclic aromatic hydrocarbons (PAHs) frequently exceeded effect-based sediment quality guidelines [probable effect concentrations (PECs)], only four of the samples had a PEC quotient (PEC-Q) for total PAHs over 1.0 and only one of these four samples was identified as toxic. For the mean PEC-Q for organochlorine compounds (chlordane, dieldrin, sum DDEs), 4 of the 12 samples with a mean PEC-Q above 1.0 were toxic and 4 of the 8 samples with a mean PEC-Q above 3.0 were toxic. Additionally, four of eight samples were toxic, with a mean PEC-Q above 1.0 based on metals, PAHs, polychlorinated biphenyls (PCBs), and organochlorine pesticides. The increase in the incidence of toxicity with the increase in the mean PEC-Q based on organochlorine pesticides or based on metals, PAHs, PCBs, and organochlorine pesticides suggests that organochlorine pesticides might have contributed to the observed toxicity and that the use of a mean PEC-Q, rather than PEC-Qs for individual compounds, might be more informative in predicting toxic effects. Our study shows that stream sediments subject to predominant nonpoint sources contamination can be toxic and that many factors, including analysis of a full suite of PAHs and pesticides of both past and present urban applications and the origins of

    1989-09-29

    The Environmental Protection Department of the US Department of Energy Kansas City Plant (DOE/KCP) requested that a risk assessment be performed on the potential health effects of discharges of polychlorinated biphenyls (PCBs) from the DOE/KCP to the Blue River Sewage Treatment Plant, Kansas City's largest publicly owned treatment works facility (Kansas City POTW). The major objectives of this risk assessment are (1) to determine the potential health impacts of DOE/KCP's current discharges of PCBs to the Kansas City POTW via all reasonable exposure pathways and (2) to determine a health-based, safe'' discharge level for PCBs to the Kansas City POTW. The present risk assessment considers both occupational and public impacts of PCB discharges from the DOE/KCP. Two occupational exposure scenarios assessed are (1) risk to Kansas City POTW sewer line maintenance workers and (2) risk to Kansas City POTW workers during routine operations of the facility. Both types of workers may be dermally exposed to PCBs in sewage. Public risks considered include risk to populations living within 50 km of the Kansas City POTW via inhalation of PCBs from sludge incinerated at the facility. Additionally, risk to the general public associated with PCB releases from the Kansas City POTW to the Missouri River is assessed. These pathways include ingestion of PCBs in drinking water supplied by the Missouri River, dermal adsorption and accidental ingestion of PCBs while swimming in the Missouri River, and ingestion of PCBs through consumption of fish taken from the Missouri River. Risk to breastfed infants from ingestion of PCBs through mothers' milk is also assessed. 108 refs., 3 figs., 5 tabs.

    1987-02-01

    Big and still growing, Mexico City and its environs is soon to be the world's largest metropolitan area. The lure of city amenties--jobs, health care, schooling, and cheap food--and the hope of a better life bring 1000 rural migrants to Mexico City every day. Between 1950 and 1980, Mexico City grew at an annual average rate of 5.4%. Mexico City is typical of Latin American supercities, holding an impressive portion of the nation's population and commanding the lion's share of the country's economic activities. It is primarily due to the rapid growth in the northern periphery of the municipalities that Mexico City is expected to grow into the world's largest metropolitan area by the year 2000. Given the high proportion of youth relative to the total population, it is not suprising that average household sizes in Mexico City are large. About 60% to 70% of all families have no access to the formal housing market; much of the urban expansion has occurred through the emergence of squatter communities. Water may indeed be the most serious of all of Mexico City's infrastructural problems. Other problems include: 1) the government cannot meet the demands for educational buildings and personnel; 2) in 1982, 10.3% of the metropolitan population lived in extreme poverty and an additional 22.6% were unable to satisfy their basic needs; and 3) transport is a central problem. Demographic sources for Mexico are discussed.

    A pilot carbon dioxide miscible flood was initiated in the Lansing Kansas City C formation in the Hall Gurney Field, Russell County, Kansas. The reservoir zone is an oomoldic carbonate located at a depth of about 2900 feet. The pilot consists of one carbon dioxide injection well and three production wells. Continuous carbon dioxide injection began on December 2, 2003. By the end of June 2005, 16.19 MM lb of carbon dioxide was injected into the pilot area. Injection was converted to water on June 21, 2005 to reduce operating costs to a breakeven level with the expectation that sufficient carbon dioxide was injected to displace the oil bank to the production wells by water injection. By March 7,2010, 8,736 bbl of oil were produced from the pilot. Production from wells to the northwest of the pilot region indicates that oil displaced from carbon dioxide injection was produced from Colliver A7, Colliver A3, Colliver A14 and Graham A4 located on adjacent leases. About 19,166 bbl of incremental oil were estimated to have been produced from these wells as of March 7, 2010. There is evidence of a directional permeability trend toward the NW through the pilot region. The majority of the injected carbon dioxide remains in the pilot region, which has been maintained at a pressure at or above the minimum miscibility pressure. Estimated oil recovery attributed to the CO2 flood is 27,902 bbl which is equivalent to a gross CO2 utilization of 4.8 MCF/bbl. The pilot project is not economic.

    This report discusses a structural load inventory database (LID) which has been developed to support configuration management at the DOE Kansas City Plant (KCP). The objective of the LID is to record loads supported by the plant structures and to provide rapid assessments of the impact of future facility modifications on structural adequacy. Development of the LID was initiated for the KCP`s Main Manufacturing Building. Field walkdowns were performed to determine all significant loads supported by the structure, including the weight of piping, service equipment, etc. These loads were compiled in the LID. Structural analyses for natural phenomena hazards were performed in accordance with UCRL-15910. Software to calculate demands on the structural members due to gravity loads, total demands including both gravity and seismic loads, and structural member demand-to-capacity ratios were also developed and integrated into the LID. Operation of the LID is menu-driven. The LID user has options to review and print existing loads and corresponding demand-to-capacity ratios, and to update the supported loads and demand-to-capacity ratios for any future facility modifications.

    2013-06-10

    Nine different streetlighting products were installed on various streets in Kansas City, Missouri during February, 2011, to evaluate their performance relative to the incumbent high-pressure sodium (HPS) lighting. The applications investigated included 100 W, 150 W, 250 W, and 400 W HPS installations. Initial measurements and comparisons included power, illuminance, and luminance; sample illuminance readings have continued at each of the nine locations at roughly 1,000-hour operating intervals since then. All of the LED products consumed less power than their HPS counterparts—with a mean difference of 39% and a range of 31% to 51%—but they also emitted 31% fewer lumens, on average. The net result is just a 15% increase in mean efficacy. Applying the city’s stringent light loss factors to the initial measured data meant that five of the LED products (and two of the HPS luminaires) were predicted to eventually fail to meet the specified mean illuminance over their lifetimes; however, the specified light loss levels are not expected to be reached by the LED products until some distant future date (between 12 and 30 years after installation according to manufacturer specification sheet estimates). The practical value of designing streetlighting systems to meet illumination requirements more than 15 years in the future is questioned. Numerous sources of variation in field measurements are noted throughout the report, particularly seasonal influences such as ambient temperature and foliage that are evident in the time-series illuminance data.

    In July 1996, the US Department of Energy (DOE) Kansas City Plant (KCP), AlliedSignal Federal Manufacturing and Technologies, and Oak Ridge National Laboratory (ORNL), conducted field-scale tests of in situ soil mixing and treatment technologies within the Northeast Area (NEA) of the KCP at the Former Ponds site. This demonstration, testing, and evaluation effort was conducted as part of the implementation of a deep soil mixing (DSM) innovative remedial technology demonstration project designed to test DSM in the low-permeability clay soils at the KCP. The clay soils and groundwater beneath this area are contaminated by volatile organic compounds (VOCs), primarily trichloroethene (TCE) and 1,2-dichloroethene (1,2-DCE). The demonstration project was originally designed to evaluate TCE and 1,2-DCE removal efficiency using soil mixing coupled with vapor stripping. Treatability study results, however, indicated that mixed region vapor stripping (MRVS) coupled with calcium oxide (dry lime powder) injection would improve TCE and 1,2-DCE removal efficiency in saturated soils. The scope of the KCP DSM demonstration evolved to implement DSM with the following in situ treatment methodologies for contaminant source reduction in soil and groundwater: DSM/MRVS coupled with calcium oxide injection; DSM/bioaugmentation; and DSM/chemical oxidation using potassium permanganate. Laboratory treatability studies were started in 1995 following collection of undisturbed soil cores from the KCP. These studies were conducted at ORNL, and the results provided information on optimum reagent concentrations and mixing ratios for the three in situ treatment agents to be implemented in the field demonstration.

    Energy Technology Data Exchange (ETDEWEB)

    1995-01-01

    The U.S. Department of Energy (DOE) has prepared this Environmental Assessment (EA) to assist the agency in complying with the National Environmental Policy Act (NEPA) of 1969 as it applies to modification of ongoing groundwater treatment at DOE`s Kansas City Plant (KCP), located about 19 km (12 miles) south of the central business district of Kansas City, Missouri. The KCP is currently owned by DOE and is operated by the Kansas City Division of AlliedSignal Inc. The plant manufactures nonnuclear components for nuclear weapons. The purpose of and need for the DOE action is to treat identified toxic organic contaminated groundwater at the KCP to ensure that human health and the environment are protected and to comply with groundwater treatment requirements of the U.S. Environmental Protection Agency (EPA) Resource Conservation and Recovery Act (RCRA) 3008(h) Administrative Order on Consent and the discharge requirements of the Kansas City, Missouri, ordinances for the city sewer system. Four source streams of toxic organic contaminated groundwater have been identified that require treatment prior to discharge to the city sewer system. The toxic organic contaminants of concern consist of volatile organic compounds (VOCS) in the groundwater and polychlorinated biphenyls (PCBS) predominantly associated with some soils near the Main Manufacturing Building. The no-action alternative is to continue with the current combination of treatment and nontreatment and to continue operation of the KCP groundwater treatment system in its current configuration at Building 97 (B97). The DOE proposed action is to collect and treat all identified toxic organic contaminated groundwater prior to discharge to the city sewer system. The proposed action includes constructing an Organics Collection System and Organics Treatment Building, moving and expanding the existing groundwater treatment system, and operating the new groundwater treatment facility.

  11. Upscaling pollutant dispersion in the Mexico City Metropolitan Area

    2012-02-01

    Pollutant emission is an important problem in megacities such as Mexico City, imposing serious threats to human health and economic activity. Public policies oriented to deal with pollutant management ought to be based upon a close understanding of the transport mechanisms involved in the commonly complex network of streets and buildings. Modeling and simulation tools have proved to be useful for understanding field measurements and developing efficient monitoring strategies. The aim of this work is to provide estimations of the (longitudinal and transverse) dispersion coefficients in upscaled models for pollutant transport in the Mexico City Metropolitan Area (MCMA). To this end, we use the method of volume averaging, which allows calculation of the dispersion coefficients by solving the associated closure problems in some representative regions of the MCMA. The results show that local geometry has an important effect upon contaminant dispersion, especially in the direction that is transverse to the pressure gradient. This suggests that, although winds can remove an important amount of atmospheric contaminants, high transversal dispersion can help in a fast spreading of contaminants within the street network.

    2015-04-01

    Full Text Available Background: Adequate dietary calcium intake favours bone mineral accrual. Sparse published data are available on dietary calcium intake of metropolitan city population from south India. Methods: We recorded the dietary intake of calcium and phytates of 524 healthy subjects from Bengaluru, a metropolitan city, by recalling the diet consumed in the previous 5 to 7 days and compared it with dietary intake of calcium of 325 healthy subjects from rural areas around Tirupati, and 508 healthy subjects from urban Tirupati. Results: The dietary calcium intake of the Tirupati rural subjects was the least compared to that of the urban and metropolitan city subjects. In the metropolitan and urban groups the diet was high in calories, milk, milk products and vegetables compared to rural subjects. Dietary calcium intake was significantly lower (p<0.0001 in the rural subjects compared to the urban and metropolitan city subjects. The dietary phytate were significantly different in both the rural, urban as well as the metropolitan city groups (p<0.0001. The dietary phytate/calcium ratio was significantly higher in rural subjects compared to urban and metropolitan city group (p<0.0001. Conclusions: Improving the quality of diet by reducing the phytate and enriching/supplementing with calcium will be of benefit for maintaining bone health.

    Full Text Available Rapid changes in information and communication technologies cause serious developments in marketing field similar to every sector. In parallel with these developments, the social media channels which appear as Web 2.0 applications have a number of advantages in comparison with traditional media channels. Social media gained a place in marketing activities because of its advantages. Social media is added on instruments in line with these developments that countries benefit in marketing activities for attracting more tourists, investment and becoming prominent against the other cities. Cities intensively benefit from social media because of social media’s properties like reaching the large masses, low marketing cost, interaction, receiving feedbacks rapidly, etc. Within this context, the purpose of this research is to determine the use statuses of social media by metropolitan municipalities as part of city marketing. In accordance with this purpose, official social media accounts of 30 metropolitan municipalities are investigated between the dates of 01/09/2016 and 30/09/2016, then their shares in social media channels are investigated in the context of city marketing.It is observed that two metropolitan municipalities do not have official Facebook accounts, four metropolitan municipalities do not have an official Twitter account as well. Again, it is found that 19 metropolitan municipalities do not have an official Instagram account and 17 metropolitan municipalities do not have official YouTube account. In consequence, it is observed that, our metropolitan municipalities do not benefit from social media effectively for city marketing activities.

    1997-12-31

    The introduction of several reformulated gasolines into the Mexico City Metropolitan Zone (MCMZ) in the middle 1986 is an example of using fuel composition to improve, in theory, the air quality. However, although these changes have resulted in an important reduction of lead airborne concentrations, a worsened situation has been created. Ozone levels in the atmosphere MCMZ have presented a sudden rise since the introduction of the first reformulated gasoline, reaching in the 1990`s an annual average of 1,700 exceedances to the Mexican Ozone Air Quality Standard (0.11 ppm not to be exceeded 1 hr. a day one day a year). The authors examine the tendency on ozone air quality in MCMZ in relation with the changes in gasoline composition since 1986. The authors also discuss the importance to perform an air quality impact analysis before the introduction of reformulated gasolines in countries where the local economy do not allow to change the old car fleet not fitted with exhaust treatment devices.

  17. Convective weather hazards in the Twin Cities Metropolitan Area, MN

    Science.gov (United States)

    Blumenfeld, Kenneth A.

    This dissertation investigates the frequency and intensity of severe convective storms, and their associated hazards, in the Twin Cities Metropolitan Area (TCMA), Minnesota. Using public severe weather reports databases and high spatial density rain gauge data, annual frequencies and return-periods are calculated for tornadoes, damaging winds, large hail, and flood-inducing rainfall. The hypothesis that severe thunderstorms and tornadoes are less likely in the central TCMA than in surrounding areas also is examined, and techniques for estimating 100-year rainfall amounts are developed and discussed. This research finds that: (i) storms capable of significant damage somewhere within the TCMA recur annually (sometimes multiple times per year), while storms virtually certain to cause such damage recur every 2-3 years; (ii) though severe weather reports data are not amenable to classical comparative statistical testing, careful treatment of them suggests all types and intensity categories of severe convective weather have been and should continue to be approximately as common in the central TCMA as in surrounding areas; and (iii) applications of Generalized Extreme Value (GEV) statistics and areal analyses of rainfall data lead to significantly larger (25-50%) estimates of 100-year rainfall amounts in the TCMA and parts of Minnesota than those currently published and used for precipitation design. The growth of the TCMA, the popular sentiment that downtown areas somehow deter severe storms and tornadoes, and the prior underestimation of extreme rainfall thresholds for precipitation design, all act to enhance local susceptibility to hazards from severe convective storms.

    1994-11-01

    The Kansas City Division of AlliedSignal Inc. has been investigating the fabrication and use of piezoelectric motors in mechanisms for United States Department of Energy (DOE) weapons applications for about four years. These motors exhibit advantages over solenoids and other electromagnetic actuators. Prototype processes have been developed for complete fabrication of motors from stock materials, including abrasive machining of piezoelectric ceramics and more traditional machining of other motor components, electrode plating and sputtering, electric poling, cleaning, bonding and assembly. Drive circuits have been fabricated and motor controls are being developed. Laboratory facilities have been established for electrical/mechanical testing and evaluation of piezo materials and completed motors. Recent project efforts have focused on the potential of piezoelectric devices for commercial and industrial use. A broad range of various motor types and application areas has been identified, primarily in Japan. The Japanese have been developing piezo motors for many years and have more recently begun commercialization. Piezoelectric motor and actuator technology is emerging in the United States and quickly gaining in commercial interest. The Kansas City Division is continuing development of piezoelectric motors and actuators for defense applications while supporting and participating in the commercialization of piezoelectric devices with private industry through various technology transfer and cooperative development initiatives.

  3. Welcoming Diversity? Symbolic Boundaries and the Politics of Normativity in Kansas City's LGBTQ Communities.

    Vogler, Stefan

    2016-01-01

    Using document analysis and ethnographic field work, this article examines the debate within the LGBTQ community of Kansas City over the decision to hold its Pride festival in the Power and Light District (P&L), a renewed downtown area with a controversial dress code. Despite the developers' and city's goals of creating a cosmopolitan urban space that welcomed diverse populations, the P&L acquired a reputation as an anti-Black, anti-queer space due to its dress code and redevelopment history. I argue that the debate surrounding this controversy reveals limits to notions of diversity and diverging approaches to sexual politics within the LGBTQ community that are normally obscured by political actors within the movement but that work to create symbolic boundaries that exclude "non-respectable" members of the LGBTQ population. Recovering queer perspectives allows us to imagine a more capacious definition of diversity and inclusion, both within the LGBTQ movement and in urban space.

    Barbosa Prieto, A

    1991-12-01

    Metropolitanization has been considered an important problem of regional development in developing countries. Attitudes toward the metropolis have been ambivalent in Latin America. On the 1 hand the metropolis is viewed as an obstacle to development that absorbs resources from the zone of influence and incurs high social costs of urbanization, but on the hand it is also viewed as a form of achieving levels of economic efficiency comparable to those of developed countries. Metropolitan areas should not be viewed as isolated, but rather as important points of demographic and manpower attraction, poles of economic growth and technological and cultural innovation. "Urban areas" and "metropolitan zones" are distinct ways of defining and delimiting urban phenomena. Although there is no consensus as to the exact definitions of these 2 urban units, it is generally accepted that the urban area is the city itself as well as the contiguous built up area reaching in all directions to the onset of nonurban land uses such as forests territorial extension that includes the politico-administrative units with urban characteristics such as work places and residences for nonagricultural workers, and that maintain constant and intense socioeconomic interrelations with the central city. The process of urban planning in the metropolitan zone of Puebla, Mexico, began in institutional form in 1980 with master plans for the population centers of Puebla, Amozoc, San Andres and San Pedro Cholula, and Zacatelco in the state of Tlaxcala. In 1987., an attempt was made by the governments of the states of Puebla and Tlaxcala to develop a plan for the metropolitan zone as a single unit. Population growth was greater within the city of Puebla than in the metropolitan zone from 1960-80, but after 1980 growth in the outlying areas exceeded that in the center city. The population density of the city of Puebla declined from 160/hectare in 1950 to 76/hectare in 1990, the result of progressive dispersion

  8. The Hydro-Economic Interdependency of Cities: Virtual Water Connections of the Phoenix, Arizona Metropolitan Area

    Richard R. Rushforth

    2015-06-01

    Full Text Available Water footprinting has revealed hydro-economic interdependencies between distant global geographies via trade, especially of agricultural and manufactured goods. However, for metropolitan areas, trade not only entails commodity flows at many scales from intra-municipal to global, but also substantial intra-metropolitan flows of the skilled labor that is essential to a city’s high-value economy. Virtual water flows between municipalities are directly relevant for municipal water supply policy and infrastructure investment because they quantify the hydro-economic dependency between neighboring municipalities. These municipalities share a physical water supply and also place demands on their neighbors’ water supplies by outsourcing labor and commodity production outside the municipal and water supply system boundary to the metropolitan area. Metropolitan area communities span dense urban cores to fringe agricultural towns, spanning a wide range of the US hydro-economy. This study quantifies water footprints and virtual water flows of the complete economy of the Phoenix Metropolitan Area’s municipalities. A novel approach utilized journey to work data to estimate virtual water flows embedded in labor. Commodities dominate virtual water flows at all scales of analysis, however labor is shown to be important for intra-metropolitan virtual water flows. This is the first detailed water footprint analysis of Phoenix, an important city in a water-scarce region. This study establishes a hydro-economic typology for communities to define several niche roles and decision making points of view. This study’s findings can be used to classify communities with respect to their relative roles, and to benchmark future improvements in water sustainability for all types of communities. More importantly, these findings motivate cooperative approaches to intra-metropolitan water supply policy that recognize the hydro-economic interdependence of these

    2012-11-01

    Full Text Available Commuting data at a district level and an algorithm designed to delineate self–contained areas show that Mexico City Metropolitan Area (MCMA was organized in 2007 in twelve local labour market areas. Although six exployment subcenters were identified, the MCMA is still clearly dominated by its Central Business District (CBD, being located the remaining five subcenters close to the CBD. Assessment of this spatial structure is not a positive one: diminishing co–location, decrease in speed and increase in commuting time and distance. Nevertheless, the rising percentage of intra–district commuting is a positive sign, even if this trend is not uniform throughout the metropolitan area.

    2016-04-01

    Dhaka Metropolitan City (including Dhaka and five adjacent municipal areas) is one of the fastest developing urban regions in the world. Densely build-up areas in the developed metropolitan area of Dhaka City are subject to extensive restructuring as common six- or lower storied buildings are replaced by higher and heavier constructions. Additional stories are built on existing houses, frequently exceeding the allowable bearing pressure on the subsoil as supported by the foundations. In turn, newly developing city areas are projected in marshy terrains modified by extensive, largely unengineered landfills. In most areas, these terrains bear unfavorable building ground conditions within 30 meters. Within a collaborative technical cooperation project between Bangladesh and Germany, BGR supports GSB in the provision of geo-information for the Capital Development Authority (RAJUK). For general urban planning, RAJUK successively develops a detailed area plan (DAP) at scale 1 : 50000 for the whole Dhaka Metropolitan City area (approx. 1700 km2). Geo-information have not been considered in the present DAP. Within the project, geospatial information in form of a geomorphic map, a digital terrain model and a 3-D subsurface model covering the whole city area have been generated at a scale of 1 : 50000. An extensive engineering geological data base consisting of more than 2200 borehole data with associated Standard Penetration Testing (SPT) and lab data has been compiled. With the field testing (SPT) and engineering geological lab data, the 3-D subsurface model can be parameterized to derive important spatial subsurface information for urban planning like bearing capacity evaluations for different foundation designs or soil liquefaction potential assessments for specific earthquake scenarios. In conjunction with inundation potential evaluations for different flooding scenarios, comprehensive building ground suitability information can be derived to support risk

    The present study was carried out to understand the current contamination status of organochlorine compounds (OCs) in human breast milk from three metropolitan cities in India (New Delhi, Mumbai and Kolkata). Among the OCs analyzed, DDTs were predominant followed by HCHs and PCBs. CHLs and HCB levels were much lower. Contamination patterns were different in human milk found in our previous study in Chennai, a metropolitan city in southern India, indicating region specific exposure routes and variable sources. In comparison with previous data, levels of DDTs and HCHs generally declined with time, implying the effect of various bans and restrictions on their usage. No association between concentrations of OCs and demographic characteristics such as parity and age of mothers was observed which might be due to narrow range of mother's age. Estimated daily intake shows that some infants are exposed to OCs to a greater extent, particularly HCHs than the guideline standard.

    Objective Mold in water-damaged homes has been linked to asthma. Our objective was to test a new metric to quantify mold exposures in asthmatic children’s homes in three widely dispersed cities in the United States. Methods The Environmental Relative Moldiness Index (ERMI) metric was created by the US Environmental Protection Agency, with assistance by the Department of Housing and Urban Development (HUD), to quantify mold contamination in US homes. The ERMI values in homes of asthmatic children were determined for the three widely dispersed cities of Boston, Kansas City, and San Diego. Results Asthmatic children in Boston (n = 76), Kansas City (n = 60), and San Diego (n = 93) were found to be living in homes with significantly higher ERMI values than were found in homes randomly selected during the 2006 HUD American Healthy Homes Survey (AHHS) from the same geographic areas (n = 34, 22, and 28, respectively). Taken together, the average ERMI value in the homes with an asthmatic child was 8.73 compared to 3.87 for the AHHS homes. In addition, Kansas City homes of children with “Mild, Moderate, or Severe Persistent Asthma” had average ERMI value of 12.4 compared to 7.9 for homes of children with only “Mild Intermittent Asthma.” Aspergillus niger was the only mold of the 36 tested which was measured in significantly greater concentration in the homes of asthmatic children in all three cities. Conclusion High ERMI values were associated with homes of asthmatic children in three widely dispersed cities in the United States. PMID:23137280

    Optical and thermal properties of soils are important input data for the meteorological and photochemical modules of air quality models. As development of these models increase on spatial resolution good albedo data become more important. In this paper measurements of surface albedo of UV (295-385 nm) and visible (450-550 nm) radiation are reported for different urban and rural surfaces in the vicinity of Mexico City. It was found for the downtown zone and average albedo value of 0.05 which is in very good agreement with reported values for urban surfaces. Our albedo values measured in UV region for grey cement and green grass are of 0.10 and 0.009, respectively, and quite similar to those found at the literature of 0.11 and 0.008 for those type of surfaces.

    2016-01-01

    Transportation noise is known to have negative impact on both public health and life quality. This study evaluated the relationship between transportation noise and annoyance levels, and also the difference of annoyance levels in two metropolitan cities based on epidemiologic surveys. Two thousand adult subjects living in Seoul and Ulsan were enrolled by stratified random sampling on the basis of noise maps from July 2015 to January 2016. Individual annoyance in accordance with transportation noise levels in two metropolitan cities were surveyed using an 11-point visual analog scale questionnaire. The results show that transportation noise level was significantly correlated with annoyance in both cities. Logistic regression analysis revealed that the risk of being 'highly annoyed' increased with noise level (Ldn, day-night average sound level) in both cities. After adjusting for age, residence period, sociodemographic factors (sex, education, marriage, income, alcohol, smoking, and exercise) and noise sensitivity, the risk of being 'highly annoyed' was increased with noise levels in both cities. In comparison to those of areas with noise levels below 55 dBA, the adjusted odds ratios of 'highly annoyed' for areas with 55-65 dBA and over 65 dBA were 2.056 (95% confidence interval [CI] 1.225-3.450), 3.519 (95% CI 1.982-6.246) in Seoul and 1.022 (95% CI 0.585-1.785), 1.704 (95% CI 1.005-2.889) in Ulsan, respectively. Based on the results of a population study, we showed that transportation noise levels were significantly associated with annoyance in adults. However, there were some differences between the two cities. In this study, there were differences in transportation noise between the two cities. Seoul has complex noise (traffic and aircraft), compared to single road traffic noise in Ulsan. Therefore, single and complex transportation noise may have different effects on annoyance levels.

    On May 4, 2007, Greensburg, Kansas, was hit by a 1.7-mile wide tornado with 200 mph-plus wind speeds. This tornado destroyed or severely damaged 90% of Greensburg?s structures. We discuss the progress made in rebuilding Greensburg, with a focus on the built environment and on meeting Greensburg?s goal of 100% renewable energy, 100% of the time. We also discuss key disaster recovery efforts that enabled Greensburg to reach this goal. Key strategies included a Sustainable Comprehensive Master Plan, an ordinance resolving that city-owned buildings achieve LEED Platinum and 42% energy savings, a strong focus on rebuilding 'right' with an integrated design process, attracting significant and sustained technical experts and national media attention, and linking renewable and energy efficiency technologies to business development. After three years, more than half the homes that have been rebuilt are rated at an average of 40% energy savings. All significant commercial buildings, including the school, hospital, banks, courthouse, and retail buildings, have been rebuilt to LEED Gold and Platinum standards and exceed 40% savings, with many exceeding 50% savings. Greensburg recently constructed a 12.5-MW community wind farm to provide all the remaining energy needed for its energy-efficient buildings and homes.

  1. Naturally occurring arsenic in the groundwater at the Kansas City Plant

    This report describes an investigation concerning the presence of arsenic in concentrations exceeding 0.4 mg/L in the groundwater under the Department of Energy's Kansas City Plant (KCP). The study consisted of four distinct phases: a thorough review of the technical literature, a historical survey of arsenic use at the facility, a laboratory study of existing techniques for determining arsenic speciation, and a field program including water, soil, and sediment sampling. The historical survey and literature review demonstrated that plant activities had not released significant quantities of arsenic to the environment but that similar occurrences of arsenic in alluvial groundwater are widespread in the midwestern United States. Laboratory studies showed that a chromatographic separation technique was necessary to accurately determine arsenic speciation for the KCP groundwater samples. Field studies revealed that naturally occurring reducing conditions prevalent in the subsurface are responsible for dissolving arsenic previously sorbed by iron oxides. Indeed, the data demonstrated that the bulk arsenic concentration of site subsoils and sediments is {approximately}7 mg/kg, whereas the arsenic content of iron oxide subsamples is as high as 84 mg/kg. Literature showed that similar concentrations of arsenic in sediments occur naturally and are capable of producing the levels of arsenic found in groundwater monitoring wells at the KCP. The study concludes, therefore, that the arsenic present in the KCP groundwater is the result of natural phenomena. 44 refs., 8 figs., 14 tabs.

  2. The marketing management of cities and metropolitan areas: from product orientation to marketing orientation

    2003-06-01

    Full Text Available The application of marketing principles in the administration of cities has been usually reduced to the use of the communication tools to try to diffuse the city’s image among the different target publics. At the same time, the development of cities has habitually been based on the endowment of infrastructures and singular buildings, by means of relatively opaque strategic planning processes. From a marketing vision, we consider indispensable to base the development of cities on the active citizenship participation, as well as in the empowerment of the tangible and intangible aspects. In the case of the Metropolitan Bilbao, the strategic plan that has been developed in the last decade was centred on tangible elements, while the new plan puts a special emphasis on the intangible aspects and civic participation.

  3. Climate Change Management Approaches of Cities: A Comparative Study Between Globally Leading and Turkish Metropolitan Cities

    Full Text Available Many studies have focused on climate change policies and action at the national level, but few have studied policies and action at the city level, especially cities in emerging economies. To address this gap, the present study analyzes the management strategies globally leading cities have developed to address climate change and related issues and compares them with the city strategies of one rapidly urbanizing emerging economy, Turkey. In the analysis, the strategic plans of five leading global cities are compared with those of sixteen Turkish cities. While the leading global cities have specific managerial approaches to mitigate climate change, none of the Turkish cities exhibits any comprehensive approach. Furthermore, while leading global cities modify urban services to reduce greenhouse gas (GHG emissions, few Turkish cities adjust any services to address this challenge. Some Turkish cities propose an increased use of renewable energy sources and modification in their transportation system, but the focus in these plans is the current daily needs of their inhabitants. The findings of this study suggest several climate change strategies both for Turkish cities and cities in other developing countries.

    Macías, P; Islas, J

    2010-09-15

    This paper presents an estimate of the externalities produced in the Mexico City Metropolitan Area (MCMA) through the impacts on health caused by secondary pollutants attributed to seven electric power plants located outside this area. An original method was developed to make possible a simplified application of the impact pathway approach to estimate the damage costs in the specified area. Our estimate shows that the annual costs attributed to secondary pollutants total 71 million USD (min/max 20/258 million USD). Finally, this paper discusses basic ideas on the implications for energy policy arising from this exercise in externality valuation.

    Thyroid cancer incidence in New York State has increased rapidly in recent years, particularly in New York City and its surrounding metropolitan area. In 2007 among white non-Hispanics, incidence rates were about 40% higher in the New York City metropolitan area than in the rest of the state. Here we explore the extent to which living in neighborhoods with a high percentage of highly observant Jews may be associated with this pattern. We identify neighborhoods with concentrations of highly observant Jewish persons based on the use of Yiddish among children and the location of Orthodox synagogues. Thyroid cancer risk is modeled as a function of living in such a neighborhood, adjusting for age, sex, and other factors. The model was repeated for small (Jewish neighborhoods and downstate New York. A lesser association was found among those who live in neighborhoods of high levels of people born in Russia, Belarus, or Ukraine. Similar elevated rate ratios were seen for small and large tumors in Jewish neighborhoods, providing evidence against differences in diagnostic practices in this group. Smaller tumors were more pronounced among women and persons diagnosed more recently. The associations found do not seem to be diagnostically driven, but rather due to environmental, genetic, or cultural factors in the highly observant population of New York State.

    The present study was carried out to understand the current contamination status of organochlorine compounds (OCs) in human breast milk from three metropolitan cities in India (New Delhi, Mumbai and Kolkata). Among the OCs analyzed, DDTs were predominant followed by HCHs and PCBs. CHLs and HCB levels were much lower. Contamination patterns were different in human milk found in our previous study in Chennai, a metropolitan city in southern India, indicating region specific exposure routes and variable sources. In comparison with previous data, levels of DDTs and HCHs generally declined with time, implying the effect of various bans and restrictions on their usage. No association between concentrations of OCs and demographic characteristics such as parity and age of mothers was observed which might be due to narrow range of mother's age. Estimated daily intake shows that some infants are exposed to OCs to a greater extent, particularly HCHs than the guideline standard. - Indian infants may be exposed to relatively high levels of DDTs and HCHs through mothers' milk.

    Green infrastructure can be a cost-effective approach for reducing stormwater runoff and improving water quality as a result, but it could also bring co-benefits for air quality: less impervious surfaces and more vegetation can decrease the urban heat island effect, and also result in more removal of air pollutants via dry deposition with increased vegetative surfaces. Cooler surface temperatures can also decrease ozone formation through the increases of NOx titration; however, cooler surface temperatures also lower the height of the boundary layer resulting in more concentrated pollutants within the same volume of air, especially for primary emitted pollutants (e.g. NOx, CO, primary particulate matter). To better understand how green infrastructure impacts air quality, the interactions between all of these processes must be considered collectively. In this study, we use a comprehensive coupled meteorology-air quality model (WRF-CMAQ) to simulate the influence of planned land use changes that include green infrastructure in Kansas City (KC) on regional meteorology and air quality. Current and future land use data was provided by the Mid-America Regional Council for 2012 and 2040 (projected land use due to population growth, city planning and green infrastructure implementation). We found that the average 2-meter temperatures (T2) during summer (June, July and August) are projected to slightly decrease over the downtown of KC and slightly increase over the newly developed regions surrounding the urban core. The planetary boundary layer (PBL) height changes are consistent with the T2 changes: the PBL height is somewhat lowered over the downtown and raised over the newly developed areas. We also saw relatively small decreases in O3 in the downtown area for the mean of all hours as well as for the maximum 8 hour average (MDA8), corresponding with the changes in T2 and PBL height. However, we also found relatively small PM2.5 concentration increases over KC, especially

    1977-10-01

    A high quality limestone is currently being mined from a deep shaft mine (1072 feet) in Middle Devonian rocks (Callaway) within the city limits of Kansas City, Missouri. About 15 acres of essentially dry space (room and pillar) with up to 14-foot ceilings have been developed. There are few natural joints observable in the rock within the mine. Some of these are periodically damp. More than 80% of the mine is dry. Saltwater from aquifers (Pennsylvanian) cut by the shaft accumulates behind the shaft at the pump station at 850 feet and at the bottom of the shaft (Devonian-Ordovician rocks). As long as the pumps lift the water to the surface, the mine can be kept relatively dry. Grouting of the aquifer's rocks in the shaft may seal off that source of water. The Burlington limestone of the Mississippian System is potentially mineable on the property now developed. The Burlington limestone, the Middle Devonian limestone, and the Kimmswick (Middle Ordovician) limestone are all potentially mineable by shaft mining in the northern part of Greater Kansas City and northward into the Forest City Basin.

    Use of secondary-treated municipal wastewater for crop irrigation south of Dodge City, Kansas, where the soils are mainly of silty clay loam texture, has raised a concern that it has resulted in high nitratenitrogen concentrations (10-50 mg/kg) in the soil and deeper vadose zone, and also in the underlying deep (20-45 m) ground water. The goal of this field-monitoring project was to assess how and under what circumstances nitrogen (N) nutrients under cultivated corn that is irrigated with this treated wastewater can reach the deep ground water of the underlying High Plains aquifer, and what can realistically be done to minimize this problem. We collected 15.2-m-deep cores for physical and chemical properties characterization; installed neutron moisture-probe access tubes and suction lysimeters for periodic measurements; sampled area monitoring, irrigation, and domestic wells; performed dye-tracer experiments to examine soil preferential-flow processes through macropores; and obtained climatic, crop, irrigation, and N-application rate records. These data and additional information were used in the comprehensive Root Zone Water Quality Model (RZWQM2) to identify key parameters and processes that influence N losses in the study area. We demonstrated that nitrate-N transport processes result in significant accumulations of N in the thick vadose zone. We also showed that nitrate-N in the underlying ground water is increasing with time and that the source of the nitrate is from the wastewater applications. RZWQM2 simulations indicated that macropore flow is generated particularly during heavy rainfall events, but during our 2005-06 simulations the total macropore flow was only about 3% of precipitation for one of two investigated sites, whereas it was more than 13% for the other site. Our calibrated model for the two wastewater-irrigated study sites indicated that reducing current levels of corn N fertilization by half or more to the level of 170 kg/ha substantially

    Five aromatic hydrocarbons (benzene, toluene, and three isomeric xylenes) were monitored in indoor and outdoor air of 7 public buildings and 54 private homes, located in Barcelona City metropolitan area and in several rural areas of Catalonia. The sampling was carried out over four periods: spring-summer and winter of 2000, and summer and winter of 2001. Passive ORSA 5 Draiger samplers were used for benzene, toluene, and xylenes (BTX) adsorption. BTX were extracted with carbon disulphide and analysed using a gas chromatograph coupled to a FID detector. In Barcelona metropolitan area the outdoor average concentrations of BTX were 3.5, 34.2, and 31.3 μg/m3 in urban areas, and 1.4, 9.2, and 9.2 μg/m3 in rural areas, respectively. Average indoor air concentrations of BTX were respectively 4.3, 64.8, and 47.6 μg/m3 in urban areas and 5.8, 67.0, and 51.4 μg/m3 in rural areas, respectively. A direct connection between the house and garage was one of the most influential factors for indoor BTX concentrations in rural areas. In urban areas, diffuse traffic sources were the predominant BTX source, slightly influenced by tobacco smoke in indoor air.

    Full Text Available A study was conducted by the United States Geological Survey (USGS at three locations in the Twin Cities Metropolitan Area in Minnesota to assess the effect that bioretention areas, or rain gardens, have on water quality. The rain gardens are located at the University of Minnesota Landscape Arboretum (MLA, City of Hugo, and City of Woodbury. These sites were chosen because of their similar ages, differences in design, surrounding land use, precipitation patterns, and geology. This article reports the statistical analysis of six years of data obtained from these three sites. The data characterizes the water quality of the inflow, overflow, vadose zone, and groundwater of each rain garden. Nutrients analyzed included chloride, total suspended solids, ammonia, organic nitrogen, nitrate, and phosphorus. Lysimeters and wells had significantly lower nutrient concentrations compared to inflow for most nutrients. Increased nitrate occurred in the vadose zone at Woodbury and Hugo, suggesting some production of nitrate within the soil profile; however, groundwater beneath the rain gardens contained significantly lower concentrations of nitrate compared to the inflow, providing evidence of nitrate removal at deeper depths. Phosphorus concentrations were reduced in overflow and groundwater, with the exception of dissolved phosphorus at MLA. Rain garden and background wells often contained similar nutrient concentrations, suggesting that the rain gardens had little impact on the local ground water supplies. This unique six year study provides consistent evidence of the ability of these three rain gardens to reduce nutrient concentrations from urban stormwater.

    Similar to most large cities, the transportation sector in the Mexico City Metropolitan Area (MCMA) constitutes the largest source of air pollution emissions, which result in significant impacts on human health. Although the majority of MCMA residents use public transportation, the share of trips in private vehicles is rising and these vehicles have become the largest contributor to mobile emissions. To reduce these emissions, there is an urgent need to improve the current fleet, improve the quality of fuels, and modify the paradigm of private car use, by providing clean, safe, efficient and comfortable public transportation options. Here we present the potential human health benefits of a set of five mobile source control measures that span public and private transportation options: Taxi fleet renovation, Hybrid buses, Metro Expansion, and the introduction of low sulfur gasoline and Tier II vehicles. We also discuss the methodology and preliminary results of the analysis of the implementation of the project for a Bus Rapid Transit system in Mexico City, in terms of its impacts on personal exposures, emissions, and public health.

    Mexico City Metropolitan Zone (MCMZ) represents an example of a megacity where the air pollution problem has reached an important evolution in a very short time, causing a risk in the health of a population of more than 20 million inhabitants. The atmospheric pollution problem in the MCMZ, began several decades ago, but it increased drastically in the middle of the 80`s. It is important to recognize that in the 60`s, 70`s and the first half of the 80`s the main pollutants were sulfur dioxide and total suspended particles. However since the second half of the 80`s until now, ozone is the most important air pollutant besides of the suspended particles (PM{sub 10}) and other toxic pollutants (1--8). The purpose of this paper is to discuss the evolution of the ozone atmospheric pollution problem in the MCMZ, as well as to analyze the results of several implemented air pollution control strategies.

    Quantitative understanding of human communication behavior, one of the fundamental human activities, is of great value in many practical problems, ranging from urban planning to emergency management. Most of the recent studies have focused on human communication under normal situations. Here, we study the temporal patterns of emergency calls, which is a special kind of human communication activity under emergency circumstances, by analyzing a dataset of emergency call records that collected from a metropolitan city in China during a five year period. We find that most individuals rarely make emergency calls. The distribution of inter-call durations decays as double power law along with an exponential tail. We also discover that, comparing with the normal communication activities, the activity of calling the emergency number shows more significant characteristics of burstiness and memory. We further demonstrate that the behavior of calling the emergency number when people encounter extreme events could be explained by an event-driven memory process.

Any two nodes of them can be connected in the network to perform quantum key distribution (QKD). An optical switching module is presented that enables arbitrary 2-connectivity among output ports. Integrated QKD terminals are worked out, which can operate either as a transmitter, a receiver, or even both at the same time. Furthermore, an additional link in another city of 60 km fiber (up to 130 km) is seamless integrated into this network based on a trusted relay architecture. On all the links, we have implemented protocol of decoy state scheme. All of necessary electrical hardware, synchronization, feedback control, network software, execution of QKD protocols are made by tailored designing, which allow a completely automatical and stable running.

    2002-01-01

    Samples were collected from 16 base-flow events and a minimum of 10 stormflow events between July 1998 and October 2000 to characterize the effects of wastewater and combined sewer overflows on water quality in the Blue River Basin, Kansas City, Missouri and Kansas. Waterquality effects were determined by analysis of nutrients, chloride, chemical and biochemical oxygen demand, and suspended sediment samples from three streams (Blue River, Brush Creek, and Indian Creek) in the basin as well as the determination of a suite of compounds known to be indicative of wastewater including antioxidants, caffeine, detergent metabolites, antimicrobials, and selected over-the-counter and prescription pharmaceuticals. Constituent loads were determined for both hydrologic regimes and a measure of the relative water-quality impact of selected stream reaches on the Blue River and Brush Creek was developed. Genetic fingerprint patterns of Escherichia coli bacteria from selected stream samples were compared to a data base of knownsource patterns to determine possible sources of bacteria. Water quality in the basin was affected by wastewater during both base flows and stormflows; however, there were two distinct sources that contributed to these effects. In the Blue River and Indian Creek, the nearly continuous discharge of treated wastewater effluent was the primary source of nutrients, wastewater indicator compounds, and pharmaceutical compounds detected in stream samples. Wastewater inputs into Brush Creek were largely the result of intermittent stormflow events that triggered the overflow of combined storm and sanitary sewers, and the subsequent discharge of untreated wastewater into the creek. A portion of the sediment, organic matter, and associated constituents from these events were trapped by a series of impoundments constructed along Brush Creek where they likely continued to affect water quality during base flow. Concentrations and loads of most wastewater constituents in

    In the town of Santa Ana in the southern part of the Mexico City Metropolitan Area (MCMA) at an approximate height of 370 meters above the Valley of Mexico, a series of criteria pollutants (nitrogen dioxide, ozone, sulfur dioxide, and carbon monoxide) and meteorological parameters (wind speed and direction, temperature and relative humidity) were measured during the MCMA-2003 field campaign during April 2003. Santa Ana is considered a border site, agriculture being the predominant activity. The generated data in Santa Ana was compared with those from two representative atmospheric monitoring stations from the southeast zone (CENICA Supersite) and southwest (Revolucion Station) of Mexico City. The carbon monoxide and ozone concentrations measured in Santa Ana are atypical for a rural area. The sulfur dioxide and nitrogen dioxide concentrations are characteristic of the local activity. The average obtained during the measurement time for carbon monoxide was 0.86 ppm, the presence of the contaminant was within a 0.3 to 1.5 ppm range, 5 to 95 percentile, and does not follow the observed behavior of the monitoring stations that are located inside the urban area, although during the night (10 pm to 6 am) the carbon monoxide in Santa Ana was preset in levels from 0.4 to 1.5 ppm, 5 to 95 percentiles, average 0.92 ppm, above the reported concentrations at Revolucion Station, levels from 0.1 to 1.7 ppm, 5 to 95 percentiles; average 0.72 ppm. The presence of this contaminant can be attributed to transportation and accumulation phenomena. The ozone daytime behavior is similar to the one observed in the CENICA and Revolucion stations, but with a lower magnitude, the daily maximum generally occuring 2 or 3 hours after the urban stations. The one-hour average maximum values were 133 ppb in Santa Ana area and 188 ppb in the city. During the night the average concentrations were 37 ppb in Santa Ana and 17 ppb in the urban area. Nevertheless, the ozone average value in Santa Ana

    Full Text Available Grid models were used to assess urban hospital distribution in Seoul, the capital of South Korea. A geographical information system (GIS based analytical model was developed and applied to assess the situation in a metropolitan area with a population exceeding 10 million. Secondary data for this analysis were obtained from multiple sources: the Korean Statistical Information Service, the Korean Hospital Association and the Statistical Geographical Information System. A grid of cells measuring 1 × 1 km was superimposed on the city map and a set of variables related to population, economy, mobility and housing were identified and measured for each cell. Socio-demographic variables were included to reflect the characteristics of each area. Analytical models were then developed using GIS software with the number of hospitals as the dependent variable. Applying multiple linear regression and geographically weighted regression models, three factors (highway and major arterial road areas; number of subway entrances; and row house areas were statistically significant in explaining the variance of hospital distribution for each cell. The overall results show that GIS is a useful tool for analysing and understanding location strategies. This approach appears a useful source of information for decision-makers concerned with the distribution of hospitals and other health care centres in a city.

Secondary data for this analysis were obtained from multiple sources: the Korean Statistical Information Service, the Korean Hospital Association and the Statistical Geographical Information System. A grid of cells measuring 1 × 1 km was superimposed on the city map and a set of variables related to population, economy, mobility and housing were identified and measured for each cell. Socio-demographic variables were included to reflect the characteristics of each area. Analytical models were then developed using GIS software with the number of hospitals as the dependent variable. Applying multiple linear regression and geographically weighted regression models, three factors (highway and major arterial road areas; number of subway entrances; and row house areas) were statistically significant in explaining the variance of hospital distribution for each cell. The overall results show that GIS is a useful tool for analysing and understanding location strategies. This approach appears a useful source of information for decision-makers concerned with the distribution of hospitals and other health care centres in a city.

    In the interest of improved public safety during flooding, the U.S. Geological Survey, in cooperation with the city of Kansas City, Missouri, completed a flood-inundation study of the Blue River in Kansas City, Missouri, from the U.S. Geological Survey streamflow gage at Kenneth Road to 63rd Street, of Indian Creek from the Kansas-Missouri border to its mouth, and of Dyke Branch from the Kansas-Missouri border to its mouth, to determine the estimated extent of flood inundation at selected flood stages on the Blue River, Indian Creek, and Dyke Branch. The results of this study spatially interpolate information provided by U.S. Geological Survey gages, Kansas City Automated Local Evaluation in Real Time gages, and the National Weather Service flood-peak prediction service that comprise the Blue River flood-alert system and are a valuable tool for public officials and residents to minimize flood deaths and damage in Kansas City. To provide public access to the information presented in this report, a World Wide Web site (http://mo.water.usgs.gov/indep/kelly/blueriver) was created that displays the results of two-dimensional modeling between Hickman Mills Drive and 63rd Street, estimated flood-inundation maps for 13 flood stages, the latest gage heights, and National Weather Service stage forecasts for each forecast location within the study area. The results of a previous study of flood inundation on the Blue River from 63rd Street to the mouth also are available. In addition the full text of this report, all tables and maps are available for download (http://pubs.usgs.gov/sir/2008/5068). Thirteen flood-inundation maps were produced at 2-foot intervals for water-surface elevations from 763.8 to 787.8 feet referenced to the Blue River at the 63rd Street Automated Local Evaluation in Real Time stream gage operated by the city of Kansas City, Missouri. Each map is associated with gages at Kenneth Road, Blue Ridge Boulevard, Kansas City (at Bannister Road), U.S. Highway 71

  4. Risk to a Changing Climate in the Mexico City Metropolitan Area

    The issue of climate change has dominated the atmospheric sciences agenda in recent decades. The concern about an increase in climate related disasters, mainly in large population centers, has led to ask whether they are mainly due to changes in climate or in vulnerability.The Mexico City Metropolitan Area (MCMA) is an example of megalopolis under high climate risk, where floods, landslides, health problems, high air pollution events, socioeconomic droughts are becoming important environmental and social problems. As urbanization spreads and population increases exposure to natural hazards increases, and so the magnitude of risk to a changing climate and the negative impacts. Since the late nineteenth century, in the MCMA an average maximum temperature could be around 22°C, whereas today it is about 24.5ºC. That is, the increase in the average temperature in Mexico City is around 3°C in a hundred years. But there are areas where an increase in the average temperature is similar in only thirty years. The heating rate of the city can vary depending on the change in land use. Areas that conserve forested regions in the process of urbanization tend to warm less than areas where the transformation into concrete and cement is almost complete. Thus, the climate of the MCMA shows important changes mainly in relation to land use changes. Global warming and natural climate variability were also analyzed as possible forcing factors of the observed warming by comparing low frequency variations in local temperature and indices for natural forcing. The hydrological cycle of the MCMA has also changed with urbanization. The "bubble of hot air" over the urban area has more capacity to hold moisture now than before the UHI. However, the increased risk to floods, heat or drought appears to be related not only to more frequent intense climatic hazards induced by the urbanization effect. This process also induces increased vulnerability to a changing climate. The establishment of

    Bathymetric and velocimetric data were collected by the U.S. Geological Survey, in cooperation with the Missouri Department of Transportation, near 8 bridges at 7 highway crossings of the Missouri River in Kansas City, Missouri, from June 2 to 4, 2015. A multibeam echosounder mapping system was used to obtain channel-bed elevations for river reaches ranging from 1,640 to 1,660 feet longitudinally and extending laterally across the active channel from bank to bank during low to moderate flood flow conditions. These bathymetric surveys indicate the channel conditions at the time of the surveys and provide characteristics of scour holes that may be useful in the development of predictive guidelines or equations for scour holes. These data also may be useful to the Missouri Department of Transportation as a low to moderate flood flow comparison to help assess the bridges for stability and integrity issues with respect to bridge scour during floods.

    According to the Mexico City Metropolitan Area (MCMA) authorities the transport sector causes 75% of total pollutant emissions to the atmosphere, that is why to mitigate pollution several programs focus on reducing emissions from mobile sources, one of these programs promotes the use of Natural Gas (NG) in vehicles of the MCMA instead of gasoline or diesel. This work shows the cost-benefit analysis results of this program. The analysis considered the period 1999-2014. Projections for the MCMA vehicular fleet, and for the type and number of vehicles that would switch from gasoline or diesel to NG were made. To obtain the change in exhaust emissions, measurements were performed using the U. S. Federal Test Procedure 75 in vehicles consuming gasoline and NG Vehicle conversion, conversion shops, and gas station costs were considered in the analysis The estimated benefits stemmed from fuel price and efficiency differential, vehicle taxes, maintenance costs, and pollutant emission reductions. The Benefit/Cost ratio found was 3.79, and the vehicles suggested for conversion were those of intensive use circulating exclusively in the MCMA. Even though ozone formation simulations were done using the CIT trajectory model, the changes in ozone concentrations observed were smaller than the model resolution, mainly because the change in ozone precursors due to the fuel change in some of the MCMA vehicles, was less than 1% of total emissions.

    PCE currently used in Bangladesh is based on the values given in Geometric Design of Highways (MoC, 2001, which is the modification of the values given by Webster (1958 on the study performed in the United Kingdom in the 50's and 60's. But now-a-days, the situation is far different both for traffic and road user as the characteristics have changed from that time. Hence, in this paper an empirical study was carried out to determine the PCE of different types of vehicle that reflect the actual traffic conditions of Dhaka Metropolitan City. Data were collected from ten signalized intersections and the headway ratio method was used to estimate the PCE of different types of vehicle. The main vehicle compositions observed during the study period consist of passenger cars, auto-rickshaws, mini-buses and buses. The PCE obtained in this study were compared to the values established earlier. It was found that the estimated PCE are smaller than those being used in Bangladesh.

    Full Text Available The aim of this study is two fold: first, to analyze the spatial distribution of health services that different public institutions offer in the metropolitan peripheral municipalities of Mexico City; and second, give some reasons that explain that distribution. The analysis tries to demonstrate a lack of territorial approach in the construction of the social policy in the particular case of the health sector. The spatial range of health service, coverage and accessibility in the eastern part of the State of Mexico was calculate through variables much as number of doctors, nurses, beds and medical center, that the different public institution particularly IMSS, ISSSTE and ISSEMYM, offer. Results tend to show an unequal distribution of health resources either human or material, as well as a territorial disorden in their distribution with a high concentration in urban areas. Thus, analysis shows that space plays a fundamental role as a structuring factor in the application of health policies and in the planning of such services.

    In this research, the quality of drinking well waters from 14 districts around Seoul metropolitan city, Korea was assessed by measuring a number of parameters with established guideline (e.g., arsenic, fluoride, nitrate nitrogen, benzene, 1,2-dichloroethene, dichloromethane, copper, and lead) and without such criteria (e.g., hardness, chloride ion, sulfate ion, ammonia nitrogen, aluminum, iron, manganese, and zinc). Physical parameters such as evaporation residue (or total dissolved solids) and turbidity were also measured. The importance of each parameter in well waters was examined in terms of the magnitude and exceedance frequency of guideline values established by international (and national) health agencies. The results of this study indicate that among the eight parameters with well-established guidelines (e.g., WHO), arsenic and lead (guideline value of 0.01 mg L(-1) for both) recorded the highest exceedance frequency of 18 and 16 well samples ranging in 0.06-136 and 2-9 mg L(-1), respectively. As such, a number of water quality parameters measured from many well waters in this urban area were in critical levels which require immediate attention for treatment and continuous monitoring.

    Understanding the oxidative capacity of the atmosphere and the formation of secondary pollutants are important issues in atmospheric chemistry. For instance, the photochemical production of tropospheric ozone (O3) is of particular interest due to its detrimental effects on both human health and agricultural ecosystems. A detailed characterization of tropospheric O3 production rates will help in the development of effective control strategies. The 2006 Mexico City Metropolitan Area field campaign (MCMA-2006) was one of four components of MILAGRO (Megacity Initiative: Local And Global Research Observations) intended to collect information on the impact of megacity emissions on local, regional and global scales. In this presentation, rates of production of Ox (Ox = O3 + NO2) species during MCMA-2006 at the supersite T0 (Instituto Mexicano del Petroleo) will be presented using different approaches based on measured and modeled concentrations of ROx (OH + HO2 + RO2) radicals. In addition, we will examine both the reactivity of OH and the contribution of specific peroxy radicals to the oxidation rate of NO to estimate the contribution of groups of VOCs (alkanes, alkenes, aromatics, oxygenated and biogenic VOCs) to the total production rate of Ox species.

    The increase in platinum (Pt) in the airborne particulate matter with size ≤2.5 µm (PM2.5) in urban environments may be interpreted as result of the abrasion and deterioration of automobile catalyst. Nowadays, about four million vehicles in Mexico City use catalytic converters, which means that their impact should be considered. In order to evaluate the contribution of Pt to environmental pollution of the metropolitan area of Mexico City (MAMC), airborne PM2.5 was collected at five different sites in the urban area (NW, NE, C, SW, SE) in 2011 during April (dry-warm season), August (rainy season) and December (dry-cold season). Analytical determinations were carried out using a ICP-MS with a collision cell and kinetic energy discrimination. The analytical and instrument performance was evaluated with standard road dust reference material (BCR-723). Median Pt concentration in the analyzed particulate was is 38.4 pg m(-3) (minimal value 1 pg m(-3) maximal value 79 pg m(-3)). Obtained Pt concentrations are higher than those reported for other urban areas. Spatial variation shows that SW had Pt concentration significantly higher than NW and C only. Seasonal variation shows that Pt median was higher in rainy season than in both dry seasons. A comparison of these results with previously reported data of PM10 from 1991 and 2003 in the same studied area shows a worrying increase in the concentration of Pt in the air environment of MAMC.

    2006-01-01

    The U.S. Geological Survey, in cooperation with the city of Kansas City, Missouri, began a study in 2003 of the lower Blue River in Kansas City, Missouri, from Gregory Boulevard to the mouth at the Missouri River to determine the estimated extent of flood inundation in the Blue River valley from flooding on the lower Blue River and from Missouri River backwater. Much of the lower Blue River flood plain is covered by industrial development. Rapid development in the upper end of the watershed has increased the volume of runoff, and thus the discharge of flood events for the Blue River. Modifications to the channel of the Blue River began in late 1983 in response to the need for flood control. By 2004, the channel had been widened and straightened from the mouth to immediately downstream from Blue Parkway to convey a 30-year flood. A two-dimensional depth-averaged flow model was used to simulate flooding within a 2-mile study reach of the Blue River between 63rd Street and Blue Parkway. Hydraulic simulation of the study reach provided information for the design and performance of proposed hydraulic structures and channel improvements and for the production of estimated flood-inundation maps and maps representing an areal distribution of water velocity, both magnitude and direction. Flood profiles of the Blue River were developed between Gregory Boulevard and 63rd Street from stage elevations calculated from high water marks from the flood of May 19, 2004; between 63rd Street and Blue Parkway from two-dimensional hydraulic modeling conducted for this study; and between Blue Parkway and the mouth from an existing one-dimensional hydraulic model by the U.S. Army Corps of Engineers. Twelve inundation maps were produced at 2-foot intervals for Blue Parkway stage elevations from 750 to 772 feet. Each map is associated with National Weather Service flood-peak forecast locations at 63rd Street, Blue Parkway, Stadium Drive, U.S. Highway 40, 12th Street, and the Missouri River

    Full Text Available The volatile organic compound (VOC distribution in the Mexico City Metropolitan Area (MCMA and its evolution as it is uplifted and transported out of the MCMA basin was studied during the 2006 MILAGRO/MIRAGE-Mex field campaign. The results show that in the morning hours in the city center, the VOC distribution is dominated by non-methane hydrocarbons (NMHCs but with a substantial contribution from oxygenated volatile organic compounds (OVOCs, predominantly from primary emissions. Alkanes account for a large part of the NMHC distribution in terms of mixing ratios. In terms of reactivity, NMHCs also dominate overall, especially in the morning hours. However, in the afternoon, as the boundary layer lifts and air is mixed and aged within the basin, the distribution changes as secondary products are formed. The WRF-Chem (Weather Research and Forecasting with Chemistry model and MOZART (Model for Ozone and Related chemical Tracers were able to reproduce the general features of the daytime cycle of the VOC OH reactivity distribution showing that NMHCs dominate the distribution except in the afternoon hours and that the VOC OH reactivity peaks in the early morning due to high morning emissions from the city into a shallow boundary layer. The WRF-Chem and MOZART models showed higher reactivity than the experimental data during the nighttime cycle, perhaps indicating problems with the modeled nighttime boundary layer height. In addition, a plume was studied in which air was advected out of the MCMA and intercepted downwind with the DOE G1 on 18~March and the NCAR C130 one day later on 19~March. A number of identical species measured aboard each aircraft gave insight into the chemical evolution of the plume as it aged and was transported as far as 1000 km downwind.

    Particle air pollution in urban agglomerations comes mostly from anthropogenic sources, mainly traffic, industrial processes, energy production, domestic and residential emissions, construction, but also a minor contribution from natural sources may be expected (bioaerosols, soil dust, marine aerosol). Once emitted into the atmosphere, this complex mixture of pollutants may be transformed as a function of the ambient conditions and the interaction among the different PM components, and also between PM components and gaseous pollutants. This system is especially complex in mega-cities due to the large emission volumes of PM components and gaseous precursors, the high variability and broad distribution of emission sources, and the possible long range transport of the polluted air masses. Speciation studies help to identify major sources of PM components with the end objective of applying plans and programs for PM pollution abatement. In this framework, concentration levels and compositions of particulate matter (PM2.5, PM10 and TSP) have been measured simultaneously at two sites in the Mexico City Metropolitan Area (T0 and CENICA) and at one site 50 km away from Mexico City (T1) during the MILAGRO campaign (1st to 31st March 2006). Spatial and time (day and night) variations have been analysed. Coarse fraction levels were higher at T1 than at CENICA and T0, contrary to what was expected. This was due to the important soil re-suspension at T1, contributing significantly to the crustal load. Moreover, crustal levels were higher during daytime than during nights at all sites, while some secondary compounds (sulphate and ammonium) presented an opposite trend. Regarding trace elements, levels of Pb, Zn and Cd were higher at T0 than at CENICA and T1, probably due to traffic contribution. Arsenic levels did not show a clear pattern, being alternatively higher at CENICA and T0. Two intense episodes of Hg particulate have been recorded, more noticeable at T1 than at the urban

    Water quality at the City of Olathe Landfill in east-central Kansas was examined in relation to hydrogeologic conditions to help determine the effects of the landfill on shallow ground water. This study focused on the Wyandotte and Plattsburg Limestones underlying the landfill. The Wyandotte Limestone underlies the entire landfill, whereas the overlying Plattsburg Limestone crops out within the landffll boundaries. Little Cedar Creek, an unnamed tributary, and a pond are located in the landfill. Water samples from seven monitoring wells and five surface-water sites in the vicinity of the City of Olathe Landfill were collected for analysis of inorganic and organic constituents. The inorganic constituents in the ground water that are most affected in the vicinity of the landfill are calcium, magnesium, sodium, bicarbonate, ammonia, barium, iron, and manganese. The dissolved- organic-carbon concentration at a seep flowing from the Plattsburg Limestone was 1,400 milligrams per liter, indicating that the landfill is affecting the water quality near the seep. Benzene was detected in all of the water samples, and the largest concentration was in a sample collected upgradient of the landfill. The benzene concentration exceeded the U.S. Environmental Protection Agency's Maximum Contaminant Level (0.005 milligram per liter) for drinking-water supplies. Six of the eight specific organic compounds detected were found in a water sample collected from the Plattsburg Limestone immediately downgradient of the landfill. No organic compoands, except benzene, were detected in samples collected from the Wyandotte Limestone downgradient of the landfill.

    In Korea, the potential of groundwater contamination in urban areas is increasing by industrial and domestic waste waters, leakage from oil storage tanks and sewage drains, leachate from municipal landfill sites and so on. Nowadays, chlorinated organic compounds such as trichloroethylene (TCE) and tetrachloroethylene (PCE), which are driving residential area as well as industrial area, are recognized as major hazardous contaminants. As well known, TCE is wisely used industrial activities such as degreasing, metal stripping, chemical manufacturing, pesticide production, coal gasification plants, creosote operation, and also used in automobile service centers, photo shops and laundries as cleaning solvent. Thus, groundwater protection in urban areas is important issue in Korea This study is to understand groundwater quality and contamination characteristics and to estimate risk assessment in Sasang industrial complex, Busan Metropolitan City. Busan Metropolitan City is located on southeastern coast of the Korean peninsula and is the second largest city in South Korea with a population of 3.8 millions. The geology of the study area is composed of andesite, andesitic tuff, biotite granite and alluvium (Kim et al., 1998). However, geology cannot be identified on the surface due to pavement and buildings. According to drill logs in the study area, the geologic section consists in landfill, fine sand, clay, gravelly clay, and biotite granite from the surface. Biotite granite appears 5.5- 6 m depth. Groundwater samples were collected at twenty sites in Sasang industrial complex. The groundwater samples are plotted on Piper's trilinear diagram, which indicates Ca-Cl2 type. The groundwater may be influenced by salt water because Sasang industrial complex is located near the mouse of Nakdong river that flows to the South Sea. The Ca-Cl2 water type may be partly influenced by anthropogenic contamination in the study area, since water type in granite area generally belongs Ca

    CMAQ/Models3 has been employed to simulate the aerosol distribution and variation during the period from 13 to 16 April 2003 over the Mexico City Metropolitan Area as part of MCMA-2003 campaign. The meteorological fields are simulated using MM5, with three one-way nested grids with horizontal resolutions of 36, 12 and 3 km and 23 sigma levels in the vertical. MM5 3DVAR system has also been incorporated into the meteorological simulations. Chemical initial and boundary conditions are interpolated from the MOZART output. The SAPRC emission inventory is developed based on the official emission inventory for MCMA in 2004. The simulated mass concentrations of different aerosol compositions, such as elemental carbon (EC), primary organic aerosol (POA), secondary organic aerosol (SOA), nitrate, ammonium, and sulfate have been compared to the measurements taken at the National Center for Environmental Research and Training (Centro Nacional de Investigacion y Capacitacion Ambiental, CENICA) super-site. Hydrocarbon-like organic aerosol (HOA) and oxygenated organic aerosol (OOA) are used as observations of POA and SOA, respectively in this study. The preliminary model results show that the temporal evolutions of EC and POA are reasonable compared with measurements. The peak time of EC and POA are basically reproduced, thus validating the emission inventory and its processing through CMAQ/Models3. But the magnitude of EC and POA are underestimated over the entire episode. The modeled nitrate and ammonium concentrations are overestimated on most of the days. There is 1-2 hour difference between the simulated peak time of nitrate and ammonium aerosols compared to observations at CENICA. The simulated mass concentrations of SOA and sulfate are significantly underestimated. The reasons of the discrepancy between simulations and measurements are due to the uncertainties existing in the emission inventory, meteorological fields, and as well as aerosol formation mechanism in the case

    One of the main air quality problems in the Mexico City Metropolitan Area (MCMA) are the high ozone levels, resulting from the photochemical reactions among precursors such as nitrogen oxides and volatile organic compounds. The MCMA air quality monitoring network includes 19 NOx and 19 O3 monitoring sites. However, no routine VOC monitoring is carried out. This work presents results of a field campaign done from September 2005 to September 2006 in the MCMA. 24 hours integrated samples were obtained every six days in five different sites, considered representative of the northwest, northeast, southeast, southwest, and center of the MCMA. Samples were obtained in stainless steel canisters adapted with a programmable flow controller. Analyses were done using a GC-FID to identify 57 VOCs following USEPA-TO-14A. A total of 354 samples were obtained corresponding to 62 sampling days. On the average, highest concentrations were found in the center, whereas lowest concentrations were found at the southwest. However, the overall maximum concentration (741 ppbV) was determined at the northeast site, and the overall minimum concentration (27 ppbV) was determined at the southwest site. At all sites, propane, butane, acetylene and toluene were the compounds found at highest concentrations. The main source for propane and butane is LPG, whereas for acetylene and toluene are combustion and evaporation of gasoline. It was found that southwest site is significantively different from the rest of all sites. A short field campaign was also done during 5 days in November-December 2005 with 3 periods of 3hrs integrated samples.

    In the Mexico City metropolitan area (MCMA), 70% of the water for 18 million inhabitants is derived from the Basin of Mexico regional aquifer. To provide an overview of the quality of the groundwater, a longitudinal study was conducted, in which 30 sites were randomly selected from 1,575 registered extraction wells. Samples were taken before and after chlorine disinfection during both the rainy and dry seasons (2000-2001). Microbiological parameters (total coliforms, fecal coliforms, streptococci, and Vibrio spp.), the presence of Helicobacter pylori, and physicochemical parameters, including the amount of trihalomethanes (THMs), were determined. Although microorganisms and inorganic and organic compounds were evident, they did not exceed current permissible limits. Chlorine levels were low, and the bacterial counts were not affected by chlorine disinfection. Eighty-four bacterial species from nine genera normally associated with fecal contamination were identified in water samples. H. pylori was detected in at least 10% of the studied samples. About 40% of the samples surpassed the THM concentration allowed by Mexican and U.S. regulations, with levels of chloroform being high. The quality of the water distributed to the MCMA varied between the rainy and dry seasons, with higher levels of pH, nitrates, chloroform, bromodichloromethane, total organic carbon, and fecal streptococci during the dry season. This study showed that the groundwater distribution system is susceptible to contamination and that there is a need for a strict, year-round disinfection strategy to ensure adequate drinking-water quality. This situation in one of the world's megacities may reflect what is happening in large urban centers in developing countries which rely on a groundwater supply.

    Full Text Available The volatile organic compound (VOC distribution in the Mexico City Metropolitan Area (MCMA and its evolution as it is uplifted and transported out of the MCMA basin was studied during the 2006 MILAGRO/MIRAGE-Mex field campaign. The results show that in the morning hours in the city center, the VOC distribution is dominated by non-methane hydrocarbons (NMHCs but with a substantial contribution from oxygenated volatile organic compounds (OVOCs, predominantly from primary emissions. Alkanes account for a large part of the NMHC distribution in terms of mixing ratios. In terms of reactivity, NMHCs also dominate overall, especially in the morning hours. However, in the afternoon, as the boundary layer lifts and air is mixed and aged within the basin, the distribution changes as secondary products are formed. The WRF-Chem (Weather Research and Forecasting with Chemistry model and MOZART (Model for Ozone and Related chemical Tracers were able to approximate the observed MCMA daytime patterns and absolute values of the VOC OH reactivity. The MOZART model is also in agreement with observations showing that NMHCs dominate the reactivity distribution except in the afternoon hours. The WRF-Chem and MOZART models showed higher reactivity than the experimental data during the nighttime cycle, perhaps indicating problems with the modeled nighttime boundary layer height.

    A northeast transport event was studied in which air originating in the MCMA was intercepted aloft with the Department of Energy (DOE G1 on 18 March and downwind with the National Center for Atmospheric Research (NCAR C130 one day later on 19 March. A number of identical species measured aboard each aircraft gave insight into the chemical evolution of the plume as it aged and was transported as far as 1000 km downwind; ozone was shown to be photochemically produced in the plume. The WRF-Chem and MOZART models were used to examine the spatial extent and temporal evolution of the plume

    Full Text Available The contribution is part of the studies conducted by the Urban Planning Board, Land Management, Environment Laboratory for the “metropolitan city” and the Big Project “Historic centre of Naples, enhancement of the UNESCO site”. Among the issues under discussion, very important for the 92 municipalities of the Metropolitan City, is the preservation of different urban identities which, although united administratively, are claiming their own cultural profile rooted in the urban space, in the architecture of places and in local resources. The work is based on the principle that the use of local resources affects the quality and perception of urban space and, as evidence of belonging to the place, it is necessary to deal its exploitation under sustainable auspices.

    A large number of unknown patients without any personal, family, or other identification details represent a unique problem in the neurological emergency services of developing countries like India in a context of legal, humanitarian, and treatment issues. These patients pose a diagnostic and management challenge to treating physicians and staff. There are sparse data on these patients. The objective of this study was to know the clinical, socio-demographic, and investigational profile of "unknown" patients. We did retrospective chart review of all "Unknown" patients from January 2002 to December 2011, who was admitted under Neurology Emergency Service at a Tertiary Care Neuropsychiatry Center in South Indian Metropolitan City. Clinical and sociodemographic characteristics and clinical outcome of the sample were analyzed. A total of 151 unknown patients were admitted during the 10 years. Out of these, 134 (88.7%) were males with the mean age of 43.8 ± 14.8 years and 95 (63%) were aged >40 years. Among them, 147 (97.4%) were from the urban vicinity, 126 (83.6%) were brought by police and 75 (49.7%) were registered as medico-legal cases. Out of these, only 3 (2%) patients had normal sensorium, whereas 101 (66.9%) presented with loss of consciousness. Forty-one (27.2%) unknown patients had a seizure disorder, 37 (24.5%) had metabolic encephalopathy, 26 (17.2%) had a stroke, 9 (6%) had neuro-infection, and 17 (11.3%) had a head injury. Deranged liver functions were seen in 65 (43%), renal derangement in 37 (24.5%), dyselectrolytemia in 42 (27.8%), and abnormal brain imaging finding in 95 (62.9%) patients. Furthermore, there were 14 (9.3%) deaths. Our findings demonstrate seizures, metabolic causes, and neuro-infections were the primary reasons for admission of unknown patients to neuro-emergency service. This novel Indian study data show the common causes of admission of unknown patients in neurology. This pattern can be useful to guide the approach of healthcare

    An air quality monitoring in three schools located in the most important industrial zone at the Northeast of the Metropolitan Area of Mexico City (MAMC) was conducted in order to determine the exposure of children to toxics contained in PM10. Particles were analyzed for metals, polycyclic aromatic hydrocarbons (PAH), organic and elemental carbon by ICP-AES, GC-MS and TOT (Sunset lab) respectively. Average concentration of PM10 was 108.4±11.6 μg/m3. Most abundant metals were Fe, Zn and Pb with concentrations ranged by 1.1-5.4 μg/m3, 0.3-2 μg/m3, and 0.18-0.63 μg/m3 respectively; the sum of the seventeen PAHs varied from 1.4 to 3.3 ng/m3 where most abundant PAH were indene[1,2,3-c,d]pyrene, benzo[b]fluoranthene, benzo[a]anthracene, chrysene, and benzo[a]pyrene. The sum of the seven carcinogenic PAH contributed in average with the 48% of the total mixture. Carcinogenic potential of PAH were obtained using toxic equivalent factors determined by Nisbet and La Goy which varied from 0.3 to 0.6 ng/ m3 of benzo[a]pyrene equivalent (BAPeq), this value is lower than the standard proposed for the European Community of 1 ng/ m3, but higher than the standard from the United Kingdom of 0.25 ng/ m3. Principal component analysis for source apportionment showed that vehicular and industrial emissions are the main sources of PM in the zone. In general, the concentrations of particles as well as concentration of metals and PAHs are lower than concentrations measured six year before, showing that the established measures have improved the air quality. Nevertheless these PM10 concentrations exceeded frequently the Mexican Standard and children are especially susceptible due to the higher risk to develop diseases if the exposure occurs at early age.

    The largest urban areas of Mexico cities have witnessed high levels of air pollution in the past few decades. The most important air pollutants are ozone and particulate matter with levels that are still far above current air quality standard, In this work we studied exhaust and evaporative emissions of Mexico City metropolitan area (MAMC) vehicles using fuels in which sulfur content was varied from 89×10-6 to 817×10-6, and calculated the ozone forming potential of emissions as well as the specific reactivity of the exhaust for each average fleet-fuel combinations. Data on emission levels were compared to those obtained in 2000 for the same vintage of vehicles. The almost twofold increase in emissions found could be due to degradation of the exhaust emissions control systems.

    In this paper, we present a hybrid approach, robust principal component geographically weighted regression (RPCGWR), in examining urbanization as a function of both extant urban land use and the effect of social and environmental factors in the Twin Cities Metropolitan Area (TCMA) of Minnesota. We used remotely sensed data to treat urbanization via the proxy of impervious surface. We then integrated two different methods, robust principal component analysis (RPCA) and geographically weighted regression (GWR) to create an innovative approach to model urbanization. The RPCGWR results show significant spatial heterogeneity in the relationships between proportion of impervious surface and the explanatory factors in the TCMA. We link this heterogeneity to the "sprawling" nature of urban land use that has moved outward from the core Twin Cities through to their suburbs and exurbs.

    Full Text Available Even though fewer people die as a result of fire than other natural disasters, such as earthquake, flood, landslide, etc., the average loss of property due to fire is high. Kathmandu Metropolitan City is becoming more vulnerable to fire due to haphazard urbanization and increase in population. To control problems due to fire, systematic studies are necessary, including fire potential mapping and risk assessment. This study applies an Analytic Hierarchy Process (AHP method in Kathmandu Metropolitan City, Nepal for generation of fire potential zonation map. The fire potential zonation map is prepared on the basis of available data of land use, fuel stations, and population density. This map shows that 58.04% of the study area falls under low fire potential zone, 32.92% falls under moderate fire potential zone and 9.04% falls under high fire potential zone. The map is also validated through major past fire incidents. The results show that the predicted fire potential zones are found to be in good agreement with past fire incidents, and, hence, the map can be used for future land-use planning.

    The uncontrolled tipping of mixed urban solid waste in landfill site causes serious negative impacts on the environment. The major issue in this context is the generation of leachate which possesses potential of polluting freshwater ecosystem including groundwater besides associated health hazards and depletion of soil fertility. In this context, a pseudo computation quantitative tool, known as leachate pollution index (LPI), has been developed by some researchers for scaling pollution potential of landfill site owing to emergence of leachate. This paper. deals with the assessment of leachate quality of existing landfill site of Kolkata situated at Dhapa waste dumping ground through evaluation of the LPI from experimental analysis of leachate. The leachate was collected from this site in different seasons. 18 parameters were tested with real leachate samples in the Environmental Engineering Laboratory of Civil Engineering Department of Jadavpur University Kolkata. The results exhibited a very high value of organic pollutants in the leachate with COD as 21,129 mg/L and also values of TDS, Fe2+, Cr, Zn, chloride and ammonical nitrogen. The LPI value of Kolkata landfill site at Dhapa was estimated and also compared with leachate quality data of other metropolitan cities viz. Mumbai, Delhi, Chennai as available in literatures. It is found that LPI of the Kolkata landfill site is highest compared to all other landfill sites of other metropolitan cities in India.

    Full Text Available Abstract Background Several studies conducted during the past two decades suggested increasing trend of childhood allergic diseases in China. However, few studies have provided detailed description of geographic variation and explored risk factors of these diseases. This study investigated the pattern and risk factors of asthma, allergic rhinitis and eczema in eight metropolitan cities in China. Methods We conducted a cross-sectional survey during November-December 2005 in eight metropolitan cities in China. A total of 23791 children aged 6-13 years participated in this survey. Questions from the standard questionnaire of the International Study of Asthma and Allergies in Children (ISAAC were used to examine the pattern of current asthma, allergic rhinitis and eczema. Logistic regression analyses were performed to assess the risk factors for childhood allergies. Results The average prevalence of childhood asthma, allergic rhinitis and eczema across the eight cities was 3∙3% (95% Confidence interval (CI: 3∙1%, 3∙6%, 9∙8% (95% CI: 9∙4%, 10∙2% and 5∙5% (95% CI: 5∙2%, 5∙8%, respectively. Factors related to lifestyle, mental health and socio-economic status were found to be associated with the prevalence of childhood allergies. These risk factors were unevenly distributed across cities and disproportionately affected the local prevalence. Conclusions There was apparent geographic variation of childhood allergies in China. Socio-environmental factors had strong impacts on the prevalence of childhood allergies; but these impacts differed across regions. Thus public health policies should specifically target at the local risk factors for each individual area.

    Bathymetric surveys were conducted by the U.S. Geological Survey, in cooperation with the Missouri Department of Transportation, on the Missouri River in the vicinity of nine bridges at seven highway crossings in Kansas City, Missouri, in March 2010. A multibeam echo sounder mapping system was used to obtain channel-bed elevations for river reaches that ranged from 1,640 to 1,800 feet long and extending from bank to bank in the main channel of the Missouri River. These bathymetric scans will be used by the Missouri Department of Transportation to assess the condition of the bridges for stability and integrity with respect to bridge scour. Bathymetric data were collected around every pier that was in water, except those at the edge of the water or in extremely shallow water, and one pier that was surrounded by a large debris raft. A scour hole was present at every pier for which bathymetric data could be obtained. The scour hole at a given pier varied in depth relative to the upstream channel bed, depending on the presence and proximity of other piers or structures upstream from the pier in question. The surveyed channel bed at the bottom of the scour hole was between 5 and 50 feet above bedrock. At bridges with drilled shaft foundations, generally there was exposure of the upstream end of the seal course and the seal course often was undermined to some extent. At one site, the minimum elevation of the scour hole at the main channel pier was about 10 feet below the bottom of the seal course, and the sides of the drilled shafts were evident in a point cloud visualization of the data at that pier. However, drilled shafts generally penetrated 20 feet into bedrock. Undermining of the seal course was evident as a sonic 'shadow' in the point cloud visualization of several of the piers. Large dune features were present in the channel at nearly all of the surveyed sites, as were numerous smaller dunes and many ripples. Several of the sites are on or near bends in the river

    A series of carbon-14 (14C) radiotracer-based microcosm experiments was conducted to assess the mechanisms and products of degradation of cis-dichloroethene (cis-DCE) and vinyl chloride (VC) in streambed sediments at the U.S. Department of Energy, Kansas City Plant in Kansas City, Missouri. The focus of the investigation was the potential for biotic and abiotic cis-DCE and VC degradation in surficial and underlying hyporheic sediment from the Blue River and its tributaries, Indian Creek and Boone Creek. Substantial degradation of [1,2-14C] cis-DCE and [1,2-14C] VC to 14C-carbon dioxide (14CO2) was observed in all viable surficial sediment microcosms prepared under oxic conditions. No significant accumulation of reductive dechlorination products was observed under these oxic incubation conditions. The results indicate that microbial mineralization processes involving direct oxidation or co-metabolic oxidation are the primary mechanisms of cis-DCE and VC biodegradation in oxic stream sediment at the Kansas City Plant. Substantial mineralization of [1,2-14C] VC also was observed in all viable surficial sediment microcosms incubated in the absence of detectable oxygen (dissolved oxygen concentrations less than 25 micrograms per liter). In general, the accumulation of mineralization products (14CO2 and 14C-methane [14CH4]) predominated with only trace-level detection of the reductive dechlorination product, 14C-ethene. In contrast, microbial degradation of [1,2-14C] cis-DCE by reductive dechlorination or mineralization was not significant in the absence of detectable oxygen. The potential for [1,2-14C] VC biodegradation also was significant in sediments from the deeper hyporheic zones under oxic conditions and in the absence of detectable oxygen. In this study, microbial degradation of [1,2-14C] cis-DCE was not significant in hyporheic sediment treatments under either oxygen condition. Taken together, the results indicate that microbial mineralization processes in

    Concussions can have a negative impact on students' ability to perform in the classroom as well as on their health and well-being. Therefore, timely treatment is especially important. To better understand the scope of the problem in Minnesota, the Minnesota Department of Health piloted an online sports-related concussion reporting system in 36 public high schools in the Twin Cities metropolitan area. In the 2013-2014 academic year, 730 concussions were reported to our system from certified athletic trainers working with those schools, with one out of every 100 athletes sustaining concussions. From this, we estimated that 2,974 sports-related concussions occurred among high school athletes statewide. This information is useful for evaluating and guiding prevention efforts and for informing clinicians on how to treat concussions.

    Near surface aerosol black carbon (BC) concentration data were collected using a seven channel Aethalometer (AE31) during June 2012-May 2013 in Kolkata (22° 34‧E, 88° 22‧N), a metropolitan city located near the land-ocean boundary in Eastern India. BC concentration shows a prominent seasonal and diurnal variation associated with the meteorological parameters. The mean BC concentration varied from 5 μg/m3 to 27 μg/m3 seasonally. The variation of BC mass concentration and its significant association with atmospheric parameters such as temperature profile, relative humidity and wind speed have been studied. Moreover, the influence of the transported air masses on BC concentration at different seasons has also been discussed. An estimation of Angstrom exponent discloses that fossil fuel combustion is a major source of BC at this location.

    An analysis of trends in hospital use and capacity by ownership status and community poverty levels for large urban and suburban areas was undertaken to examine changes that may have important implications for the future of the hospital safety net in large metropolitan areas. Using data on general acute care hospitals located in the 100 largest cities and their suburbs for the years 1996, 1999, and 2002, we examined a number of measures of use and capacity, including staffed beds, admissions, outpatient and emergency department visits, trauma centers, and positron emission tomography scanners. Over the 6-year period, the number of for-profit, nonprofit, and public hospitals declined in both cities and suburbs, with public hospitals showing the largest percentage of decreases. By 2002, for-profit hospitals were responsible for more Medicaid admissions than public hospitals for the 100 largest cities combined. Public hospitals, however, maintained the longest Medicaid average length of stay. The proportion of urban hospital resources located in high poverty cities was slightly higher than the proportion of urban population living in high poverty cities. However, the results demonstrate for the first time, a highly disproportionate share of hospital resources and use among suburbs with a low poverty rate compared to suburbs with a high poverty rate. High poverty communities represented the greatest proportion of suburban population in 2000 but had the smallest proportion of hospital use and specialty care capacity, whereas the opposite was true of low poverty suburbs. The results raise questions about the effects of the expanding role of private hospitals as safety net providers, and have implications for poor residents in high poverty suburban areas, and for urban safety net hospitals that care for poor suburban residents in surrounding communities.

    The University of Kansas School of Medicine established a rural regional campus in Salina, Kansas, in 2011. The creation of a four-year medical campus of only 32 total students in a town of less than 50,000 inhabitants appeared to contradict all previous practices where medical schools have been situated in large metropolitan cities with student bodies frequently in the hundreds. The rationale to open the Salina campus was to attract medical students with a desire to train in a rural environment, hoping that many would eventually elect to practice primary care in rural Kansas. The authors evaluated the admission demographics, academic performance, campus satisfaction, and graduate medical education choices of students at Kansas University School of Medicine-Salina (KUSM-S) during its first four years of existence. To date, the Salina campus has succeeded in its mission to train students from rural communities in a rural environment to eventually become rural-based physicians. KUSM-S students have adjusted well to the rigors of medical school, have shown steady improvement in academic performance as measured by United States Medical Licensing Examination scores, and have been overwhelmingly positive about the Salina medical education program. The initial cohort of students has now successfully graduated and secured residency training positions, and most KUSM-S graduates are either continuing their training in primary care in Kansas or intend to return to Kansas to practice following residency training.

    The Allied-Signal Aerospace Company currently operates a production facility in Kansas City, Missouri, under contract with the US Department of Energy (DOE). Over the years the operation of the DOE Kansas City Plant has resulted in the contamination of groundwater with chlorinated hydrocarbons, including trichloroethene (TCE). One of the plumes of contaminated groundwater, the underground tank farm (UTF) plume, was selected for remediation with an advanced oxidation process (AOP) consisting of simultaneous treatment by ozone (O{sub 3}), ultraviolet (UV) radiation, and hydrogen peroxide (H{sub 2}O{sub 2}). Since the use of AOPs is relatively new for the removal of organics from groundwater, information on design criteria, costs, performance, and operating experience is not well documented in the literature. Therefore, the Oak Ridge National Laboratory (ORNL) was requested to evaluate the treatment process. This report documents the work performed through FY 1989. The results of the initial year of the evaluations, FY 1988, have been published previously, and the evaluation will continue at least through FY 1990. This report first briefly describes the treatment plant and the mechanisms of the treatment process. Next, the methodology and the results from the evaluation are discussed. Finally, conclusions and recommendations are presented. 8 refs., 14 figs., 16 tabs.

    This project was one of three collaborating grants funded by DOE/ASP to characterize the fine particulate matter (PM) and secondary PM precursors in the Mexico City Metropolitan Area (MCMA) during the MILAGRO Campaign. The overall effort of MCMA-2006, one of the four components, focused on i) examination of the primary emissions of fine particles and precursor gases leading to photochemical production of atmospheric oxidants and secondary aerosol particles; ii) measurement and analysis of secondary oxidants and secondary fine PM production, with particular emphasis on secondary organic aerosol (SOA), and iii) evaluation of the photochemical and meteorological processes characteristic of the Mexico City Basin. The collaborative teams pursued the goals through three main tasks: i) analyses of fine PM and secondary PM precursor gaseous species data taken during the MCMA-2002/2003 campaigns and preparation of publications; ii) planning of the MILAGRO Campaign and deployment of the instrument around the MCMA; and iii) analysis of MCMA-2006 data and publication preparation.

    Full Text Available Aerosols play an important role in the atmosphere but are poorly characterized, particularly in urban areas like the Mexico City Metropolitan Area (MCMA. The chemical composition of urban particles must be known to assess their effects on the environment, and specific particulate emissions sources should be identified to establish effective pollution control standards. For these reasons, samples of particulate matter ≤2.5 μm (PM2.5 were collected during the MCMA-2003 Field Campaign for elemental and multivariate analyses. Proton-Induced X-ray Emission (PIXE, Proton-Elastic Scattering Analysis (PESA and Scanning Transmission Ion Microscopy (STIM techniques were done to determine concentrations of 19 elements from Na to Pb, hydrogen, and total mass, respectively. The most abundant elements from PIXE analysis were S, Si, K, Fe, Ca, and Al, while the major emissions sources associated with these elements were industry, wind-blown soil, and biomass burning. Wind trajectories suggest that metals associated with industrial emissions came from northern areas of the city whereas soil aerosols came from the southwest and increased in concentration during dry conditions. Elemental markers for fuel oil combustion V and Ni correlated with a large SO2 plume to suggest an anthropogenic, rather than volcanic, emissions source. By subtracting major components of soil and sulfate determined by PIXE analysis from STIM total mass measurements, we estimate that approximately 50% of non-volatile PM2.5 consisted of carbonaceous material.

    This paper takes metropolitan area of Chongqing Municipally, as an example. Chongqing, located at the tail area of the Three Gorges Reservoir, is a typically in-land hilly city in China. A series of serious eco-environmental hazard affecting hilly city have appeared: the forest landscape has been fragmented; the stability of ecological system has not been maintained; soil erosion has been serious; geological disasters have become more and more frequented; the phenomenon of citv "heat islands" is obvious." and environmental pollution is worsened with low physical self-puri-ficatian. All of the hazards above will affect ecological security of the tail area the the Three Gorges Reservoir and sus-tainable development of Chongqing. In order to guarantee ecological security and health of Chongqing and the Three Gorges Reservoir, the countermeasures for ecological infrastructure construction are put forward: quickly drawing up ecological infrastrueture planning of Chongqing Municipality, strengthening the integration and continuation of hilly, water spatial pattern, maintaining the diversity and stability of local ecosystem, establishing the green space system in-cluding suburban forest farmland and green space, recovering wetland ecosystem, optimizing industrial structure and urrban spatial distribution, developing recycling economy, establishing ecological infrastrucmre monitoring network and information forecast system, carrying out ecological management for Chongqing Municipality and so on.

    Full Text Available In 2008 and 2010, the Philippine government’s National Book Development Board (NBDB and Light Railway Transit Authority (LRTA launched Tulaan sa Tren, a project “designed to provide train passengers with an appreciation for Philippine Literature as they listen to their favorite celebrities reading poems about Manila over the public announcement system of LRT Line 2 stations” (goodnewspilipinas.com. This project also initiated a poetry writing contest and produced poetry anthologies that predominantly depicted views of the city and city life. Part appreciation, part revaluation, part critique, this paper initiates a sensing of: (1 the train as a figure of modern life; (2 NBDB and LRTA’s enterprise as a state measure to bridge the disparity between the public’s reception to Philippine literature and the intelligentsia’s academic way of life; and (3 literary representations of the city in the poetry anthologies this project produced, namely Train of Thought: Poems from Tulaan sa Tren and Off the Beaten Track: Poems from Tulaan sa Tren 2. This paper argues that the institutional intervention of popularizing travel, literature, and the city may be seen as a way of generating a socio-political and literary consciousness among train commuters who are linked to and implicated in the issues and anxieties of their lives in the urban environment. By analyzing the poems in the anthologies, this essay ultimately critiques Tulaan sa Tren’s attempt at nation building, identity making, and city mapping.

    During its relatively short historic period, the Atlantic Seaboard of North America has experienced a few M6+ earthquakes. These events raise the specter of a similar earthquake occurring anywhere along the eastern seaboard, including in the greater New York City (NYC) metropolitan area. Indeed, the NYC Seismic Zone is one of several concentrations of earthquake activity that stand out in the field of epicenters over eastern North America. Various lines of evidence point to a maximum magnitude in the M7 range for metropolitan NYC - a dramatic scenario that is counterbalanced by the low probability of such an event. Several faults mapped near NYC strike NW, sub-normal to the NE-striking structural trends of the Appalachians, and all earthquake sequences with well-established fault sources in the NYC seismic zone originate from NW-striking faults. With funding from the USGS Earthquake Hazard Program, we recently (July 2016) collected 85 km of high-resolution sub-bottom (CHIRP) profiles along the north shore of western Long Island Sound, immediately adjacent to metropolitan NYC. This survey area is characterized by a smooth, 15.5 kyr-old erosional surface and overlying strata with small original relief. CHIRP sonar profiles of these reflectors are expected to resolve fault or fold-related vertical relief (if present) greater than 50 cm. They would also resolve horizontal fault displacements with similar resolution, as may be expressed by offsets of either sedimentary or geomorphic features. No sedimentary cover on the land portion of the metro area offers such ideal reference surfaces, which are continuous in both time and space. Seismic profiles have a spacing of 200 m and have been acquired mostly perpendicular to the NW-striking faults mapped on land. These new data will be analyzed systematically for all resolvable features and then interpreted, distinguishing sedimentary, geomorphic, and tectonic features.

    The air pollution resulting from the intense activity in the city of Mexico is aggravated by the topographical and meteorological conditions which determine its climate. The city is ringed by mountains and the air cannot easily circulate. Moreover, the Valley of Mexico is exposed to high levels of solar radiation which induce photochemical reactions in the pollutants in the atmosphere. The strategies for reducing vehicular pollution are: producing fuels to environmental standards, improving and expanding public transport and discouraging the use of the private car, introducing systems and measures for monitoring polluting vehicles emissions.

    Rail yards serve as major nodes that facilitate delivery of cargo to the consignee. The level of operational efficiency maintained within rail yards determines whether customers receive cargo late. Various external and internal factors can impede the operational efficiency of rail yards. The future growth of rail industry depends on how well it manages a potentially serious problem inherent to all railroads--rail congestion. This study reviews the processes that occur within the Knoche rail yard, which is located in Kansas City, Kansas. In an effort to improve the operational efficiency of the Knoche rail yard or to minimize congestion, the study will reveal the results of analyzing varying strategies to improve the operational efficiency of a single event, the rip track facility, within the Knoche rail yard. This study reveals that the operational efficiency of the Knoche rail yard may be enhanced if the following occur: (1) increase the rip track facility queue population from fifteen to twenty-two, and (2) spot bad order cars directly onto the two tracks leading into the rip track facility. Finally, the amount of double handling by switch engines daily may be decreased by as much as 96% within the rail yard.

    Full Text Available Planning is a crucial element for any development initiative. Planning entails choice making in pursuit of stated goals e.g. improving living conditions for individuals and societies. Planning initiatives are employed within social systems that are governed by institution, and planning intervenes with and may reconfigure these institutions resulting in social change. This paper discusses how urban sustainability can be achieved through strategic action in urban development by analysing the planning process of Khulna city, Bangladesh. This paper reviews different scholarly articles to draw a conceptual framework for identifying the interface of strategic planning, components of strategic action planning and urban sustainability. Based on this conceptual framework this paper identifies the scope of achieving urban sustainability through analysing the current planning practice of Khulna city, Bangladesh. This paper identifies that though the Khulna city plan adopted the approach of strategic planning but it failed to comply with its theoretical notion to achieve the issues related to urban sustainability. Analysis reveals that in terms of social attribute that recognizes the interest of different group of people the exiting planning packages is not sustainable. Similar phenomenon have been observed in terms of recognition of gender and marginalized people in planning, equitable provision of income and employment generation, peoples’ participation in planning and polices for ensuring equitable access to infrastructure services. Therefore the existing planning package of Khulna city failed to achieve the issues of urban sustainability through its adapted strategic planning approach.

    Mexico City is a megalopolis with severe pollution problems caused by vehicles and industrial activity. This condition imposes important risks to human health and economic activity. Based on hourly-sampled data during the last decade, in a recent work (Meraz et al., 2015) we showed that the pollutant dynamics in Mexico City exhibits long-term and scale-dependent persistence effects resulting from the combination of pollutants generation by vehicles and removal by advection mechanisms. In this work, we analyzed the dynamics of ozone, a key component reflecting the degree of atmospheric contamination, to determine if its long-term correlations are asymmetric in relation to the actual concentration trend (increasing or decreasing). The analysis is conducted with detrended fluctuation analysis. The results showed that the average ozone dynamics is uncorrelated when the concentration is increasing. In contrast, the ozone dynamics shows long-term anti-persistence effects when the concentration is decreasing.

    Full Text Available The paper analyses the occupation process of agricultural land with social origin and urban uses in the metropolitan area of the city of Toluca (ZMCT, and the barriers that the population and authorities have to face in order to regularize the settlements. A mixed research method was applied, which included the use of quantitative and qualitative methods, on the basis of a theoretical analysis, to build a methodological research model, which was applied to an empirical case in municipal and metropolitan areas. The analysis of the 14 municipalities that constitute ZMCT shows that the barriers for regularizing settlements in land of social origin are the result of legal/administrative inefficiencies due to the incapability of local city halls to address the collective needs of society.

    Urbanization is an increasingly pervasive form of land transformation that reduces biodiversity of many taxonomic groups. Beetles exhibit a broad range of responses to urbanization, likely due to the high functional diversity in this order. Carrion beetles (Order: Coleoptera, Family: Silphidae) provide an important ecosystem service by promoting decomposition of small-bodied carcasses, and have previously been found to decline due to forest fragmentation caused by urbanization. However, New York City (NYC) and many other cities have fairly large continuous forest patches that support dense populations of small mammals, and thus may harbor relatively robust carrion beetle communities in city parks. In this study, we investigated carrion beetle community composition, abundance and diversity in forest patches along an urban-to-rural gradient spanning the urban core (Central Park, NYC) to outlying rural areas. We conducted an additional study comparing the current carrion beetle community at a single suburban site in Westchester County, NY that was intensively surveyed in the early 1970's. We collected a total of 2,170 carrion beetles from eight species at 13 sites along this gradient. We report little to no effect of urbanization on carrion beetle diversity, although two species were not detected in any urban parks. Nicrophorus tomentosus was the most abundant species at all sites and seemed to dominate the urban communities, potentially due to its generalist habits and shallower burying depth compared to the other beetles surveyed. Variation between species body size, habitat specialization, and % forest area surrounding the surveyed sites also did not influence carrion beetle communities. Lastly, we found few significant differences in relative abundance of 10 different carrion beetle species between 1974 and 2015 at a single site in Westchester County, NY, although two of the rare species in the early 1970's were not detected in 2015. These results indicate that

In this study, we investigated carrion beetle community composition, abundance and diversity in forest patches along an urban-to-rural gradient spanning the urban core (Central Park, NYC) to outlying rural areas. We conducted an additional study comparing the current carrion beetle community at a single suburban site in Westchester County, NY that was intensively surveyed in the early 1970’s. We collected a total of 2,170 carrion beetles from eight species at 13 sites along this gradient. We report little to no effect of urbanization on carrion beetle diversity, although two species were not detected in any urban parks. Nicrophorus tomentosus was the most abundant species at all sites and seemed to dominate the urban communities, potentially due to its generalist habits and shallower burying depth compared to the other beetles surveyed. Variation between species body size, habitat specialization, and % forest area surrounding the surveyed sites also did not influence carrion beetle communities. Lastly, we found few significant differences in relative abundance of 10 different carrion beetle species between 1974 and 2015 at a single site in Westchester County, NY, although two of the rare species in the early 1970’s were not detected in 2015. These results indicate

    Full Text Available The present study measured the community prevalence and risk factors of adult pulmonary tuberculosis (PTB in Chennai city, and also studied geographical distribution and the presence of different M. tuberculosis strains in the survey area.A community-based cross sectional survey was carried out from July 2010 to October 2012 in Chennai city. Prevalence of bacteriologically positive PTB was estimated by direct standardization method. Univariate and multivariate analyses were carried out to identify significant risk factors. Drug susceptibility testing and spoligotyping was performed on isolated M. tuberculosis strains. Mapping of PTB cases was done using geographic positioning systems.Of 59,957 eligible people, 55,617 were screened by X-ray and /or TB symptoms and the prevalence of smear, culture, and bacteriologically positive PTB was estimated to be 228 (95% CI 189-265, 259 (95% CI 217-299 and 349 (95% CI 330-428 per 100,000 population, respectively. Prevalence of smear, culture, and bacteriologically positive PTB was highest amongst men aged 55-64 years. Multivariate analysis showed that occurrence of both culture and bacteriologically positive PTB disease was significantly associated with: age >35 years, past history of TB treatment, BMI <18.5 Kgs/m2, solid cooking fuel, and being a male currently consuming alcohol. The most frequent spoligotype family was East African Indian. Spatial distribution showed that a high proportion of patients were clustered in the densely populated north eastern part of the city.Our findings demonstrate that TB is a major public health problem in this urban area of south India, and support the use of intensified case finding in high risk groups. Undernutrition, slum dwelling, indoor air pollution and alcohol intake are modifiable risk factors for TB disease.

    A continuously growing number of municipalities has optical fiber networks supporting communications at their disposal. These fiber installations can also be utilized to convey low data optical signals from a large number of deployed sensing elements, usually positioned in critical infrastructure locations, providing a variety of useful information. Such information can be used in the context of a "smart city" to provide citizens with higher-level services or even to proactively ensure public security and safety. This work demonstrates a fiber sensing network based on low-cost fiber Bragg grating sensors that are able to appropriately oversee diverse monitoring parameters.

    2017-01-11

    Mexico City Metropolitan Area (MCMA) is the most populated urban area in the country. In 2010, MCMA required 14.8% of total energy domestic demand, but greenhouse gas emissions accounted for 7.7% of domestic emissions. Mexico has massive renewable energy potential that could be harnessed through solar photovoltaic (PV) technology. The problem to explore is the relationship between local and federal public strategies in MCMA and their stance on energy transition concern, social empowerment, new technology appropriation, and the will to boost social development and urban sustainability. A public policy typology was conducted through instruments of State intervention approach, based on political agenda articulation and environmental local interactions. Social equality is encouraged by means of forthright funding and in-kind support and energy policies focus on non-renewable energy subsidies and electric transmission infrastructure investment. There is a lack of vision for using PV technology as a guiding axis for marginalized population development. It is essential to promote economic and political rearrangement in order to level and structure environmental governance. It is essential to understand people's representation about their own needs along with renewable energy.

    In the spring of 2003 (April 1-May 5), a multinational team of experts conducted an intensive, five-week field campaign in the Mexico City Metropolitan Area (MCMA). The overall goal of this effort was to contribute to the understanding of the air quality problem in megacities. As part of the campaign the Aerodyne Mobile Laboratory was equipped with state-of-the-art analytical instruments and deployed for measuring a variety of vehicle emissions in real time including CO2, NO2, NH3, HCHO, VOC's and volatile (at 600 °C) aerosol. The on-road measurement of vehicle VOC emissions were performed using a commercial version of the IONICON PTR-MS modified to operate onboard the mobile lab platform. A summary of the PTR-MS results from these and supporting laboratory experiments will be presented and discussed. In particular, selected chase events will be presented to illustrate the utility of the PTR-MS technique for characterizing vehicle VOC emission profiles in real time. VOC emission profiles for different vehicle engine types which include gasoline, diesel and compressed natural gas will be discussed and compared to the measurements from other high time response instruments deployed on the Aerodyne mobile van.

    2016-09-01

    Full Text Available For realizing sustainable development, EV (Electric Vehicle is currently considered as one of the most promising alternative due to its cleanness and inexhaustibility. However, the development and dissemination of EV has stagnated because it faces major constraints such as battery performance and an excessively long charging time. Thus, this study examined the feasibility of using EVs as taxis by analyzing real data from a pilot project in Daejeon, a metropolitan city in South Korea for proposing the effective way to adopt EV. To reflect reality and improve accuracy, we adopted scenarios and assumptions based on in-depth interviews with groups of experts. The resulting initial benefit-to-cost (B/C ratio for EV taxis is approximately 0.4, which is quite low compared to 0.7 for traditional taxis. However, after incorporating some further assumptions into the calculation, the B/C ratio shifts to approximately 0.7, which is more appropriate for EV adoption. For this improvement to be achieved, the dissemination of a charging infrastructure, improvement of the business model and policy support is strongly needed. Limitations to this work and potential areas for future study are also fully discussed.

    Full Text Available Street dust often contains elevated concentrations of heavy metals and can influence on environment and human health. Therefore, a study on the characteristics of heavy metals in street dusts at different localities was carried out in the metropolitan city of Kathmandu of Nepal. A total of 20 street dusts have been sampled from four sampling sites with various activities or characteristics such as mechanical workshops (MWK, motor parks (MPK, market areas (MKA and residential areas (RDA and analyzed for Zn, Pb, Ni, Cr and Cd using the atomic absorption spectrophotometric method. Results showed that street dust samples contained significant levels of the metals studied compared to the values from the control site. The variation in concentration of most of the heavy metals determined decreased in an order represented as MWK>MPK>MKA>RDA>Control. While the RDA and MKA give the same element abundance order as Zn > Pb > Ni > Cr > Cd, the MPK and MWK show different abundance order in some elemental contents. In all the street dusts, zinc is the most available and labile element followed by lead. From the place of low activity (RDA to the place of high activity (MWK, the metal concentrations in street dusts varied from 55.4-419.3 μg g-1 for Zn, 12.3-116.8 μg g-1 for Pb, 4.9-86.3 μg g-1 for Ni, 1.4-14.3 μg g-1 for Cr and 0.3-39.6 μg g-1 for Cd respectively. Results indicate that the metal pollutants in street dusts could significantly contribute to deteriorate the environmental status of the city of Kathmandu metropolis.

    Full Text Available Transportation planning for any city evolves on the basis of complex interplay between urban activity, transport and land use system to result in varied travel patterns. Travel pattern can be defined at micro level to include individual journey departure and arrival time, journey duration and distances to make way for temporal trip generation and distribution from specific area. Trip generation is the first step of four stages of travel forecasting analysis mostly followed all over the world. Traditionally, it is focused on the prediction of aggregate trip generation by a household rather than the choice of individual activity participation. However, spatial and temporal activity domains are equally important in forecasting process and strategic urban transportation planning. The present paper attempts to develop Activity Based (AB Temporal Trip Generation Models (ABTGM for primary activities to cover work and educational trips considering fast growing Surat city of Gujarat, India as study area. Home interview surveys are carried to provide household and socioeconomic characteristics and the activity travel diary information to focus on the activity based tours rather the trips.

    Full Text Available The right to city begins to be recently consecrated by academic research, presenting several links with the “sustainable development” paradigm. UN documents see our contemporary world as an “urban global world”, confronted with issues as chronic poverty, lack of access to basic urban services, insufficient democratic participation to main decisions regarding the urban management. This new right can be regarded as derived from solidarity rights as the right to a healthy, clean, durable environment, as well as the right to continuous improvement of life quality, but also, it can be seen as a special, distinct kind of human right. Right to have clean, sustainable cities can be recognized, at national, regional, international levels, to individuals, to local groups (as the metropolitan inhabitants of one city or to nations (having at their disposal a collective new right to own prosperous, sustainable cities, as effect of their right to economic development. We consider the right to city as being a dynamic right, in full process of exploration and consecration within academic research, more than necessary for understanding an urban globalized world characterized by proliferation of metropolises, towns, cities, megalopolises that demand new juridical approaches.

    The Blue River Channel Modification project being implemented by the U.S. Army Corps of Engineers (USACE) is intended to provide flood protection within the Blue River valley in the Kansas City, Mo., metropolitan area. In the latest phase of the project, concerns have arisen about preserving the Civil War historic area of Byram's Ford and the associated Big Blue Battlefield while providing flood protection for the Byram's Ford Industrial Park. In 1996, the USACE used a physical model built at the Waterways Experiment Station (WES) in Vicksburg, Miss., to examine the feasibility of a proposed grade control structure (GCS) that would be placed downstream from the historic river crossing of Byram's Ford to provide a subtle transition of flow from the natural channel to the modified channel. The U.S. Geological Survey (USGS), in cooperation with the USACE, modified an existing two-dimensional finite element surface-water model of the river between 63d Street and Blue Parkway (the 'original model'), used the modified model to simulate the existing (as of 2006) unimproved channel and the proposed channel modifications and GCS, and analyzed the results from the simulations and those from the WES physical model. Modifications were made to the original model to create a model that represents existing (2006) conditions between the north end of Swope Park immediately upstream from 63d Street and the upstream limit of channel improvement on the Blue River (the 'model of existing conditions'). The model of existing conditions was calibrated to two measured floods. The model of existing conditions also was modified to create a model that represents conditions along the same reach of the Blue River with proposed channel modifications and the proposed GCS (the 'model of proposed conditions'). The models of existing conditions and proposed conditions were used to simulate the 30-, 50-, and 100-year recurrence floods. The discharge from the calibration flood of May 15, 1990, also

    On October 29, 2012, Hurricane Sandy (Sandy) made landfall in densely populated areas of New York, New Jersey, and Connecticut. Flooding affected 51 square miles (132 square kilometers) of New York City (NYC) and resulted in 43 deaths, many caused by drowning in the home, along with numerous storm-related injuries. Thousands of those affected were survivors of the World Trade Center (WTC) disaster of September 11, 2001 (9/11) who had previously enrolled in the WTC Health Registry (Registry) cohort study. To assess Sandy-related injuries and associated risk factors among those who lived in Hurricane Sandy-flooded areas and elsewhere, the NYC Department of Health and Mental Hygiene surveyed 8,870 WTC survivors, who had provided physical and mental health updates 8 to 16 months before Sandy. Approximately 10% of the respondents in flooded areas reported injuries in the first week after Sandy; nearly 75% of those had more than one injury. Injuries occurred during evacuation and clean-up/repair of damaged or destroyed homes. Hurricane preparation and precautionary messages emphasizing potential for injury hazards during both evacuation and clean-up or repair of damaged residences might help mitigate the occurrence and severity of injury after a hurricane.

    In 1994, public hearings were held in Quebec city concerning a 120 megawatt (MW) gas cogeneration project that was to be coupled with an already existing pulp and paper mill in the downtown area. Cogeneration plants are often described as highly beneficial from the point of view of local environment. It is well known that the burning of natural gas emits far less sulfur dioxide (SO{sub 2}) and particulate matters (PM) than the combustion of oil or coal. The proposed plant would use high pressure vapour from a nearby incinerator plant and natural gas to produce low pressure vapor for the paper mill industry as well as electricity. The cogeneration plant would allow the paper mill to stop burning heavy oil. By using natural gas instead of heavy oil, the new cogeneration-paper mill complex (CPC) is expected to reinforce the recent trend and willingness towards improving downtown air quality. On the other hand, the CPC would emit more CO{sub 2}, due to the production of additional electricity. According to the Rio de Janeiro Agreement ratified in 1988, Canada is committed to stabilize its greenhouse gas emissions by the year 2000. Nevertheless, the cogeneration file is a new option considered by the Quebec Provincial Governement in its last energy triennal plan. However, it must be specified that the Province of Quebec contributes to less than 15 % of the total Canadian CO{sub 2} production although it represents more than 25 % of its population. Furthermore the maximum production of electricity by this file has been set to 250 MW. It is a very small fraction of the total production of electricity in Quebec, which is 200 TW

    The chronic health effects associated with sustained exposures to high concentrations of air pollutants are an important issue for millions of megacity residents and millions more living in smaller urban and rural areas. Particulate matter (PM) and ozone (O3) concentrations close or above their respective air quality standards during the last 20 years affect 24 million people living in the Mexico City Metropolitan Area (MCMA). Herein we discuss PM and O3 trends in MCMA and their possible association with the observed central nervous system (CNS) effects in clinically healthy children. We argue that prenatal and postnatal sustained exposures to a natural environmental exposure chamber contribute to detrimental neural responses. The emerging picture for MCMA children shows systemic inflammation, immunodysregulation at both systemic and brain levels, oxidative stress, neuroinflammation, small blood vessel pathology, and an intrathecal inflammatory process, along with the early neuropathological hallmarks for Alzheimer and Parkinson's diseases. Exposed brains are briskly responding to their harmful environment and setting the bases for structural and volumetric changes, cognitive, olfactory, auditory and vestibular deficits and long term neurodegenerative consequences. We need to improve our understanding of the PM pediatric short and long term CNS impact through multidisciplinary research. Public health benefit can be achieved by integrating interventions that reduce fine PM levels and pediatric exposures and establishing preventative screening programs targeting pediatric populations that are most at risk. We fully expect that the health of 24 million residents is important and blocking pediatric air pollution research and hiding critical information that ought to be available to our population, health, education and social workers is not in the best interest of our children.

    Air and soil sampling was conducted inside a forested area for 22 months. The sampling location is situated to the north of a metropolitan city. Average atmospheric gas and particle concentrations were found to be 180 and 28 pg m(-3) respectively, while that of soil phase was detected to be 3.2 ng g(-1) on dry matter, The congener pairs of PCB#4-10 had the highest contribution to each medium. TEQ concentration was 0.10 pg m(-3), 0.07 pg m(-3), 21.92 pg g(-1), for gas, particle and soil phases, respectively. PCB#126 and PCB#169 contributed to over 99% of the entire TEQ concentrations for each medium. Local sources were investigated by conditional probability function (CPF) and soil/air fugacity. Landfilling area and medical waste incinerator, located to the 8 km northeast, contributed to ambient concentrations, especially in terms of dioxin-like congeners. The industrial settlement (called Dilovasi being to the east southeast of 60 km distant) contributed from southeast direction. Further sources were identified by potential source contribution function (PSCF). Sources at close proximity had high contribution. Air mass transportation from Aliaga industrial region (being to the southwest of 300 km distant) moderately contributed to ambient concentrations. Low molecular weight congeners were released from soil body. 5-CBs and 6-CBs were close to equilibrium state between soil/air interfaces. PCB#171 was close to equilibrium and PCB#180 was likely to evaporate from soil, which constitute 7-CBs. PCB#199, representing 8-CBs deposited to soil. 9-CB (PCB#207) was in equilibrium between soil and air phases.

    Full Text Available Background: The Department of Health (DoH at the City of Johannesburg metropolitan municipality in South Africa develops various health awareness campaigns aimed at creating awareness of general health risks within the Johannesburg area. According to staff members of the DoH, the resources utilised in the current campaigns fail to reach a sufficiently broad audience and the campaigns struggle to deliver the intended messages. Furthermore, the development and implementation of campaigns are time consuming and costly.Objectives: This research focused on how online social networking (OSN can support health awareness campaigns for the DoH in the Johannesburg region. OSN may be regarded as a tool that will assist the DoH to reach a wider audience, send health-related messages and provide a two-way communication channel.Method: The research used an exploratory research design with a purposive non-probability sample. A survey was used as the data collection instrument. Statistical analysis was performed on the data obtained from the surveys.Results: The results indicate that the DoH can benefit from the use of OSN in health promotion campaigns. The benefits include, but are not limited to, an increase in engagement with the target market, ease of use and reach within the specified audience.Conclusion: Although there are numerous advantages associated with the integration of OSN by the DoH, the DoH needs to develop training and development programmes for OSN to encourage its use by DoH staff members. The main aim of the programmes is to create internal OSN capabilities to support the OSN strategy.

    The Mexico City Metropolitan Zone (MCMZ) presents important emissions of hazardous air pollutants. It is well documented that the MCMZ suffers a critical air pollution problem due to high ozone and particulate matter concentrations. However, toxic air pollutants such as benzene and toluene have not been considered. Benzene has accumulated sufficient evidence as a human carcinogen, and the ratio benzene/toluene is an excellent indicator to evaluate control strategies efficiency. In order to evaluate the levels of these two air toxic pollutants in the MCMZ, ambient air samples were collected in canisters and analyzed with a gas chromatograph with a flame ionization detector, according to procedures described in the United States Environmental Protection Agency (USEPA) method TO-15. Quality assurance was performed collecting duplicate samples which were analyzed in replicate to quantify the precision of air-quality measurements. Three different sites located in the Southwestern area in the MCMZ were selected for the sampling: the University campus, a gas station, and a vertical condominium area, in the same neighborhood, which presents different activities. At these sites, grab air samples were collected during the morning hours (7-8 a.m.), while for the University area, 24 h integrated air samples were collected simultaneously, with grab samples. Benzene concentrations (24 h sampling) in the atmosphere around the University campus have similar present levels as in other cities of North America. Mean values in this site were about 1.7 ppb. A significant variation exists between the benzene and toluene concentrations in the studied sites, being the more critical values than those registered at the gas station (an average of 25.8 ppb and a maximum of 141 ppb of benzene). There is a fuel regulation for gasoline in Mexico, which allows a maximum of 1 percent of benzene. However, since more than 60 percent of vehicles do not have catalytic converters (models before 1991

    Aerosols scatter or absorb incoming solar radiation, perturb the temperature structure of the atmosphere, and impact meteorological fields and further the distribution of gas phase species and aerosols. In the present study, the aerosol radiative effects on the meteorology and photochemistry in the Mexico City Metropolitan Area (MCMA) are investigated using the WRF-CHEM model during the period from March 24th to 29th associated with the MILAGRO-2006 campaign. Aerosols decrease incoming solar radiation by up to 20% and reduce the surface temperature by up to 0.5 °C due to scattering and absorbing the incoming solar radiation in Mexico City. The absorption of black carbon aerosols can also enhance slightly the temperature in the planetary boundary layer (PBL). Generally, the change of the PBL height in the city is less than 200 m during daytime due to the aerosol-induced perturbation of temperature profile. Wind fields are also adjusted with the variation of temperatures, but all the aerosol-induced meteorological changes cannot significantly influence the distribution of pollutants in the city. In addition, when convective events occur in the city, the aerosol radiative effects reduce the convective available potential energy (CAPE) and the convective precipitation is generally decreased. Further studies still need to be performed to evaluate the aerosol indirect effect on precipitation in Mexico City.

    With grant funding from the John Templeton Spirituality and Medicine Curricular Award to the George Washington Institute for Spirituality and Health, faculty at Kansas City University of Medicine and Biosciences (KCUMB) developed the "Spirituality in Medicine" curriculum. In developing the curriculum, faculty took into consideration competencies required by the Association of American Medical Colleges and qualitative results from surveys of medical school applicants and enrolled students. Strategies for curriculum delivery included lectures, panel discussions, role-playing, and training in the use of a spirituality assessment tool. A majority of the 250 students who received the training in 2010-2011 were able to demonstrate the following competencies: (1) being sensitive to patients' spiritual and cultural needs, (2) assessing patients' and their own spiritual needs, (3) appropriately using chaplain services for patient care, and (4) understanding the effects of health disparities and ethical issues on patient care. Challenges to implementation included a reduction in chaplain availability due to the economic downturn, a lack of student exposure to direct patient care during shadowing, too little religious diversity among chaplains, and changes in assignment schedules. New competencies required by the National Board of Osteopathic Medical Examiners overlap with and help ensure sustainability of the Spirituality in Medicine curriculum. KCUMB leaders have incorporated the use of the spirituality assessment tool into other parts of the curriculum and into service experiences, and they have introduced a new elective in palliative care. Synergistic efforts by faculty leaders for this initiative were critical to the implementation of this curriculum.

    This project was one of three collaborating grants funded by DOE/ASP to characterize the fine particulate matter (PM) and secondary PM precursors in the Mexico City Metropolitan Area (MCMA) during the MILAGRO Campaign. The overall effort of MCMA-2006, one of the four components, focused on i) examination of the primary emissions of fine particles and precursor gases leading to photochemical production of atmospheric oxidants and secondary aerosol particles; ii) measurement and analysis of secondary oxidants and secondary fine PM production, with particular emphasis on secondary organic aerosol (SOA), and iii) evaluation of the photochemical and meteorological processes characteristic of the Mexico City Basin. The collaborative teams pursued the goals through three main tasks: i) analyses of fine PM and secondary PM precursor gaseous species data taken during the MCMA-2002/2003 campaigns and preparation of publications; ii) planning of the MILAGRO Campaign and deployment of the instrument around the MCMA; and iii) analysis of MCMA-2006 data and publication preparation. The measurement phase of the MILAGRO Campaign was successfully completed in March 2006 with excellent participation from the international scientific community and outstanding cooperation from the Mexican government agencies and institutions. The project reported here was led by the Massachusetts Institute of Technology/Molina Center for Energy and the Environment (MIT/MCE2) team and coordinated with DOE/ASP-funded collaborators at Aerodyne Research Inc., University of Colorado at Boulder and Montana State University. Currently 24 papers documenting the findings from this project have been published. The results from the project have improved significantly our understanding of the meteorological and photochemical processes contributing to the formation of ozone, secondary aerosols and other pollutants. Key findings from the MCMA-2003 include a vastly improved speciated emissions inventory from on

    The U.S. Geological Survey, in cooperation with the U.S. Army Corps of Engineers, monitored suspended sediment within constructed Missouri River chutes during March through October 2012. Chutes were constructed at selected river bends by the U.S. Army Corps of Engineers to help mitigate aquatic habitat lost through the creation and maintenance of the navigation channel on the Missouri River. The restoration and development of chutes is one method for creating shallow-water habitat within the Missouri River to meet requirements established by the amended 2000 Biological Opinion. Understanding geomorphic channel-evolution processes and sediment transport is important for the design of chutes, monitoring and maintenance of existing chutes, and characterizing the habitat that the chutes provide. This report describes the methods used to monitor suspended sediment at two Missouri River chutes and presents the results of the data analysis to help understand the suspended-sediment characteristics of each chute and the effect the chutes have on the Missouri River. Upper Hamburg chute, near Nebraska City, Nebraska, and Kansas chute, near Peru, Nebraska, were selected for monitoring. At each study site, monthly discrete samples were collected from April through October in the Missouri River main-channel transects upstream from the chute inlet, downstream from the chute outlet, at the outlet (downstream transect) of both chutes, and at the inlet (upstream transect) of Kansas chute. In addition, grab samples from all chute sampling locations were collected using autosamplers. Suspended-sediment concentration (SSC) and grain-size metrics were determined for all samples (discrete and grab). Continuous water-quality monitors recorded turbidity and water temperature at 15-minute intervals at the three chute sampling locations. Two acoustic Doppler velocimeters, one within each chute, measured water depth and current velocities continuously. The depth and velocity data were used to

    Water levels during 2003 through 2013 were less than mean water levels for the period 1925–2013 for several lakes in the northeast Twin Cities Metropolitan Area in Minnesota. Previous periods of low lake-water levels generally were correlated with periods with less than mean precipitation. Increases in groundwater withdrawals and land-use changes have brought into question whether or not recent (2003–13) lake-water-level declines are solely caused by decreases in precipitation. A thorough understanding of groundwater and surface-water exchanges was needed to assess the effect of water-management decisions on lake-water levels. To address this need, the U.S. Geological Survey, in cooperation with the Metropolitan Council and the Minnesota Department of Health, developed and calibrated a three-dimensional, steady-state groundwater-flow model representing 2003–13 mean hydrologic conditions to assess groundwater and lake-water exchanges, and the effects of groundwater withdrawals and precipitation on water levels of 96 lakes in the northeast Twin Cities Metropolitan Area.Lake-water budgets for the calibrated groundwater-flow model indicated that groundwater is flowing into lakes in the northeast Twin Cities Metropolitan Area and lakes are providing water to underlying aquifers. Lake-water outflow to the simulated groundwater system was a major outflow component for Big Marine Lake, Lake Elmo, Snail Lake, and White Bear Lake, accounting for 45 to 64 percent of the total outflows from the lakes. Evaporation and transpiration from the lake surface ranged from 19 to 52 percent of the total outflow from the four lakes. Groundwater withdrawals and precipitation were varied from the 2003‒13 mean values used in the calibrated model (30-percent changes in groundwater withdrawals and 5-percent changes in precipitation) for hypothetical scenarios to assess the effects of groundwater withdrawals and precipitation on water budgets and levels in Big Marine Lake, Snail Lake

    Full Text Available The last two decades have seen a growing trend towards the research of voting behavior in post-communist countries. Urban sociology theorists state that not only space structures influence political participation, but also space structures are changing under the influence of global, local, and individual factors. The growing role played by information in the globalised world has accelerated the paradigm shift in urban sociology: from central place model (based on urban-rural distinction and on monocentric metropolitan areas to network society (based on space of flows and polycentric metropolitan areas. However, recent studies have mainly focused on countries with solid democracies, rather than on former communist countries. The present study aims to analyze the extent to which a new emerging spatial structure can be envisaged within a metropolitan area of Romania and its consequences for the political dimensions of social capital.The Transilvania University Ethics Commission approved this study (S1 Aprouval. The research is based upon individual and aggregate empirical data, collected from the areas adjacent to the core city in Brașov metropolitan area. Individual data has been collected during October 2012, using the oral survey technique (S1 Survey, based on a standardized questionnaire (stratified simple random sample, N = 600. The National Institute of Statistics and the Electoral Register provided the aggregate data per locality. Unvaried and multivariate analyses (hierarchical regression method were conducted based on these data.Some dimensions of urbanism, identified as predictors of the political dimensions of social capital, suggest that the area under analysis has a predominantly monocentric character, where the rural-urban distinction continues to remain relevant. There are also arguments favoring the dissolution of the rural-urban distinction and the emergence of polycentric spatial structures. The presence of some influences

  19. Successful recruiting strategies for geoscience degrees and careers at the two-year college: An example from Metropolitan Community College - Kansas City

    Wolfe, B.

    2012-12-01

    The overwhelming majority of students at 2-year colleges take geoscience courses (e.g. physical geology or physical geography) to fulfill part of the general education requirements of the Associates in Arts degree or General Education certificates for transfer to a 4-year school. It is common in community college earth science programs to have a relatively small number of students continuing on to major in geoscience programs at their transfer 4-year institution. To increase interest and retention in geosciences courses, we have developed a two prong approach - one aimed at students looking to transfer to a 4-year institution and the other aimed at students in the often overlooked career and technical education (CTE) programs. In the case of transfer students, we employ a "high touch" approach in introductory Physical Geology courses. This includes raising awareness of geoscience related careers combined with faculty mentor and advisor activities for students who express interest in science on their admission forms or in discussions of potential careers in science in first-year experience courses. Faculty mentorships have been very effective, not only in recruiting students to consider careers in geology, but also in advising a curriculum for students necessary to be successful upon transfer to a 4-year institution (such as completing college level chemistry, physics, and calculus courses prior to transfer). The second approach focuses on students pursuing certificates and degrees in CTE energy-related programs (such as HVAC, industrial engineering technology, electrician, and utility linemen). To increase awareness of vocational related geoscience careers, many of which require a good foundation in the vocational training students are currently pursing, we developed a foundation energy course - Energy and the Environment - which fulfills both the science general education component of the AA degree for students looking to transfer as well as CTE students. The curriculum focuses on fundamental concepts of energy generation and environmental impact, including analysis of energy fundamentals, fossil fuel exploration and use, atmospheric pollution, global climate change, nuclear energy, alternative energy sources, and energy conservation, all of which are directly related to geologic processes. This new course is part of newly created energy certificate programs in Photovoltaics, energy efficiency, and solar thermal - with the intention of expanding to AAS degrees in each.

    Water levels declined from 2003 to 2011 in many lakes in Ramsey and Washington Counties in the northeast Twin Cities Metropolitan Area, Minnesota; however, water levels in other northeast Twin Cities Metropolitan Area lakes increased during the same period. Groundwater and surface-water exchanges can be important in determining lake levels where these exchanges are an important component of the water budget of a lake. An understanding of groundwater and surface-water exchanges in the northeast Twin Cities Metropolitan Area has been limited by the lack of hydrologic data. The U.S. Geological Survey, in cooperation with the Metropolitan Council and Minnesota Department of Health, completed a field and statistical study assessing lake-water levels and regional and local groundwater and surface-water exchanges near northeast Twin Cities Metropolitan Area lakes. This report documents the analysis of collected hydrologic, water-quality, and geophysical data; and existing hydrologic and geologic data to (1) assess the effect of physical setting and climate on lake-level fluctuations of selected lakes, (2) estimate potential percentages of surface-water contributions to well water across the northeast Twin Cities Metropolitan Area, (3) estimate general ages for waters extracted from the wells, and (4) assess groundwater inflow to lakes and lake-water outflow to aquifers downgradient from White Bear Lake. Statistical analyses of lake levels during short-term (2002–10) and long-term (1925–2014) periods were completed to help understand lake-level changes across the northeast Twin Cities Metropolitan Area. Comparison of 2002–10 lake levels to several landscape and geologic characteristics explained variability in lake-level changes for 96 northeast Twin Cities Metropolitan Area lakes. Application of several statistical methods determined that (1) closed-basin lakes (without an active outlet) had larger lake-level declines than flow-through lakes with an outlet; (2

    The objective of this study was to assess the iodine status of pregnant women in a metropolitan city which was stated as iodine sufficient area after salt iodination program. This multicenter, cross-sectional study was carried out on 3543 pregnant women. Age, gestational weeks, smoking, consumption of iodized salt, dietary salt restriction, history of stillbirth, abortus and congenital malformations were questioned. Spot urine samples were analyzed for urine iodine concentration (UIC). The outcomes were: (a) median UIC in three trimesters of pregnancy and (b) frequency of ID among pregnant women. The median UIC was 73 µg/L. The median UIC was 77 µg/L (1-324), 73 µg/L (1-600) and 70 µg/L (1-1650) in three trimesters of pregnancy, respectively (p: 0.14). UIC <50 µg/L was observed in 36.6% (n: 1295) and UIC<150 µg/L was observed in 90.7% (n: 3214) of pregnant women. Only 1% (n: 34) of the pregnant women had UIC levels higher than 500 µg/L. This study showed that more than 90% of the pregnant women in this iodine-sufficient city are facing some degree of iodine deficiency during their pregnancy. A salt iodization program might be satisfactory for the non-pregnant population, but it seems to be insufficient for the pregnant population.

  7. Removal of PM10 by Forests as a Nature-Based Solution for Air Quality Improvement in the Metropolitan City of Rome

    Full Text Available Nature-based solutions have been identified by the European Union as being critical for the enhancement of environmental qualities in cities, where urban and peri-urban forests play a key role in air quality amelioration through pollutant removal. A remote sensing and geographic information system (GIS approach was applied to the Metropolitan City (MC of Rome to assess the seasonal particulate matter (PM10 removal capacity of evergreen (broadleaves and conifers and deciduous species. Moreover, a monetary evaluation of PM10 removal was performed on the basis of pollution externalities calculated for Europe. Deciduous broadleaves represent the most abundant tree functional group and also yielded the highest total annual PM10 deposition values (1769 Mg. By contrast, PM10 removal efficiency (Mg·ha−1 was 15%–22% higher in evergreen than in deciduous species. To assess the different removal capacity of the three functional groups in an area with homogeneous environmental conditions, a study case was performed in a peri-urban forest protected natural reserve (Castelporziano Presidential Estate. This study case highlighted the importance of deciduous species in summer and of evergreen communities as regards the annual PM10 removal balance. The monetary evaluation indicated that the overall PM10 removal value of the MC of Rome amounted to 161.78 million Euros. Our study lends further support to the crucial role played by nature-based solutions for human well-being in urban areas.

  8. Simulation of groundwater flow, effects of artificial recharge, and storage volume changes in the Equus Beds aquifer near the city of Wichita, Kansas well field, 1935–2008

    2013-01-01

    The Equus Beds aquifer is a primary water-supply source for Wichita, Kansas and the surrounding area because of shallow depth to water, large saturated thickness, and generally good water quality. Substantial water-level declines in the Equus Beds aquifer have resulted from pumping groundwater for agricultural and municipal needs, as well as periodic drought conditions. In March 2006, the city of Wichita began construction of the Equus Beds Aquifer Storage and Recovery project to store and later recover groundwater, and to form a hydraulic barrier to the known chloride-brine plume near Burrton, Kansas. In October 2009, the U.S. Geological Survey, in cooperation with the city of Wichita, began a study to determine groundwater flow in the area of the Wichita well field, and chloride transport from the Arkansas River and Burrton oilfield to the Wichita well field. Groundwater flow was simulated for the Equus Beds aquifer using the three-dimensional finite-difference groundwater-flow model MODFLOW-2000. The model simulates steady-state and transient conditions. The groundwater-flow model was calibrated by adjusting model input data and model geometry until model results matched field observations within an acceptable level of accuracy. The root mean square (RMS) error for water-level observations for the steady-state calibration simulation is 9.82 feet. The ratio of the RMS error to the total head loss in the model area is 0.049 and the mean error for water-level observations is 3.86 feet. The difference between flow into the model and flow out of the model across all model boundaries is -0.08 percent of total flow for the steady-state calibration. The RMS error for water-level observations for the transient calibration simulation is 2.48 feet, the ratio of the RMS error to the total head loss in the model area is 0.0124, and the mean error for water-level observations is 0.03 feet. The RMS error calculated for observed and simulated base flow gains or losses for the

    In metropolitan regions,the change in the strength of"flows" between a core city and surrounding cities reflects the range of the core city's influence,while the gravity between core city and other cities reflects the strength of potential relation between them.This article firstly attempts to delimit the boundary of metropolitan regions with the two dimensions measure combining "flows" and gravitation.The former is measured through the flow of people between the core city and surrounding cities,and the latter is measured through both population and gross domestic products (GDP) of the core city and surrounding cities.The hierarchy of the cities within a metropolitan region is classifted in order to emphasize the roles of the cities belonging to the metropolitan regions,different from the general way through population scale and administrative level,and is typical in China.This paper uses the Shanghai metropolitan region as a research case,determining boundary of this metropolitan region clearly and classifying hierarchy of the cities within the region.The final results are significantly different to previous work,even overthrowing the traditional system of urban hierarchy partly.It is helpful to highlight the function of cities in organizing the regional economy,the level structure of metropolitan regions,and each city's relative importance in a metropolitan region,which can be taken as scientific basis for planning integrated regions or urban systems.

    This piece of research deals with the monitoring of a group of emerging contaminants (ECs) in the metropolitan area of Granada, a city representative of the South of Spain, in order to evaluate the environmental management of the wastewater system. With that aim, the spatial and seasonal occurrence and distribution of a group of ECs in groundwater, surface and irrigation water resources from the aquifer "Vega de Granada" (VG) have been investigated for the first time. A set of the most prescribed drugs in Spain (ibuprofen, loratadine, pantoprazole and paracetamol), a pesticide widely used in agriculture (atrazine) and a typical anthropogenic contaminant (caffeine) were included in the study. Water samples were taken from the metropolitan area of the city of Granada inside of the zone of the aquifer, from the downstream of two waste water treatment plants (WWTPs) and from the two main irrigation channels where surface and wastewater are mixed before distribution for irrigation purposes in the crops of the study area. A total of 153 water samples were analyzed through liquid chromatography coupled with mass spectrometry (LC-MS/MS) throughout the study that took place over a period of two years, from July 2011 to July 2013. Results demonstrated the occurrence of four of the six target pollutants. Ibuprofen was detected several times, always in both channels with concentration ranges from 5.3 to 20.8 μg/L. The occurrence of paracetamol was detected in rivers and channels up to 34.3 μg/L. Caffeine was detected in all the water resources up to 39.3 μg/L. Pantoprazole was detected twice in the surface water source near to a WWPT ranging from 0.02 to 0.05 μg/L. The pesticide atrazine and the drug loratadine were not detected in any of the water samples analyzed. These results show evidence of poor environmental management of the wastewater concerning the water quality of the aquifer studied. The groundwater sources seem to receive a very continuous input of wastewater

In October 2009, the U.S. Geological Survey, in cooperation with the city of Wichita, began a study to determine groundwater flow in the area of the Wichita well field, and chloride transport from the Arkansas River and Burrton oilfield to the Wichita well field. Groundwater flow was simulated for the Equus Beds aquifer using the three-dimensional finite-difference groundwater-flow model MODFLOW-2000. The model simulates steady-state and transient conditions. The groundwater-flow model was calibrated by adjusting model input data and model geometry until model results matched field observations within an acceptable level of accuracy. The root mean square (RMS) error for water-level observations for the steady-state calibration simulation is 9.82 feet. The ratio of the RMS error to the total head loss in the model area is 0.049 and the mean error for water-level observations is 3.86 feet. The difference between flow into the model and flow out of the model across all model boundaries is -0.08 percent of total flow for the steady-state calibration. The RMS error for water-level observations for the transient calibration simulation is 2.48 feet, the ratio of the RMS error to the total head loss in the model area is 0.0124, and the mean error for water-level observations is 0.03 feet. The RMS error calculated for observed and simulated base flow gains or losses for the

    This study assessed the prevalence of overweight in public school first graders and the association between overweight and socio-environmental factors in a city in Greater Metropolitan São Paulo, Brazil. Children enrolling in public school first grade in Cajamar in 2005 were assessed. Overweight was defined according to body mass index, by gender and age. Socio-environmental information was obtained using a questionnaire applied to 58.6% of the children's mothers. Poisson regression models were used to evaluate associations between overweight in schoolchildren and socio-environmental variables. Seventeen percent of the children were overweight. Factors associated with overweight were: mother's obesity (PR = 3.54; CI: 2.16-5.80), high consumption of junk food (PR = 2.12; CI: 1.30-3.45), more than 4 hours a day watching TV (PR = 2.08; CI: 1.03-4.20), and daily household per capita availability of vegetal oil (around 3 tablespoons) (PR = 1.52; CI: 1.01-2.31). The family environment has a strong influence on overweight in children entering first grade in public schools. Prevention of childhood overweight should preferably target the parents and other caregivers.

    Full Text Available Objective. To conduct a health impact assessment (HIA to quantify health benefits for several PM and O3 air pollution reduction scenarios in the Mexico City Metropolitan Area (MCMA. Results from this HIA will contribute to the scientific support of the MCMA air quality management plan (PROAIRE for the period 2011-2020. Materials and methods. The HIA methodology consisted of four steps: 1 selection of the air pollution reduction scenarios, 2 identification of the at-risk population and health outcomes for the 2005 baseline scenario, 3 selection of concentration-response functions and 4 estimation of health impacts. Results. Reductions of PM10 levels to 20 μg/m3 and O3 levels to 0.050ppm (98 µg/m3 would prevent 2300 and 400 annual deaths respectively. The greatest health impact was seen in the over-65 age group and in mortality due to cardiopulmonary and cardiovascular disease. Conclusion. Improved air quality in the MCMA could provide significant health benefits through focusing interventions by exposure zones.

    The objectives of this funded project were (a) to further analyze the data collected by our group and collaborators in Mexico City during the MCMA-2003 field campaign, with the goal of further our understanding of aerosol sources and processes; and (b) to deploy several advanced instruments, including the newly developed high-resolution time-of-flight aerosol mass spectrometer (HR-ToF-AMS) and thermal-denuder (TD), during the MILAGRO/MAX-Mex/MCMA-2006 field campaign, and to analyze those data (together with the 2003 data) to provide additional insights on the formation and transformation of aerosols in the Mexico City area. These goals were addressed in collaboration with our project partners, MIT/Molina Center, and Aerodyne Research. Overall this project was very successful, resulting on 22+ journal papers including six “highly cited papers” and three papers that are the most cited in their respective journals (out of several thousand papers) since the year in which they were published. Multiple discoveries, such as the the underestimation of SOA in urban areas even for short photochemical ages, the demonstration that urban POA is of similar or higher volatility than urban SOA, and the first analysis of organic aerosol elemental composition in real-time have been recently published. Several dozen presentations at major US and international conferences and seminars also acknowledged this grant.

    Full Text Available Las grandes ciudades latinoamericanas se debaten actualmente entre dos procesos de transformación socio-territorial convergentes: la densificación y verticalización de las áreas centrales, y la expansión cada vez más difusa y fragmentada de los suburbios. Esta dicotomía entre ciudad compacta y ciudad dispersa parece mostrar procesos singulares en el caso de la región metropolitana de Buenos Aires. A partir de los años dos mil, se han ralentizado los nuevos lanzamientos de urbanizaciones cerradas y, paralelamente, han comenzado a manifestarse algunos casos de revitalización de antiguas subcentralidades del sur de la metrópolis, que habían entrado en una fase de estancamiento y deterioro desde mediados de los años setenta, y actualmente experimentan una aceleración de la producción de vivienda multifamiliar de calidad. Este trabajo explora y muestra algunas experiencias concretas de esta tendencia, con la hipótesis que, al menos en Buenos Aires, los procesos de transformación y reestructuración metrolitana muestran complejidades y diversidades según los contextos temporales y territoriales que se analicen. The large Latin American cities are currently experiencing two convergent socio-territoria transformation processes: the densification and verticalization of central areas, and the increasingly diffuse and fragmented suburban expansion. This dichotomy between the compact city and the dispersed city seems to show unique features in the case of the metropolitan region of Buenos Aires. After the 2000s, the expansion of gated communities has slowed down and at the same time some old subcentralities in the South of the metropolis have begun to revitalize. Since the mid-1970s, they had entered a phase of stagnation and deterioration, and at present the production of quality multifamily housing is rapidly growing. This paper reflects on this trend and show some concrete experiences. Our hypothesis is that in Buenos Aires the process

    Full Text Available New primary and secondary organic aerosol modules have been added to PMCAMx, a three dimensional chemical transport model (CTM, for use with the SAPRC99 chemistry mechanism based on recent smog chamber studies. The new modelling framework is based on the volatility basis-set approach: both primary and secondary organic components are assumed to be semivolatile and photochemically reactive and are distributed in logarithmically spaced volatility bins. This new framework with the use of the new volatility basis parameters for low-NOx and high-NOx conditions tends to predict 4–6 times higher anthropogenic SOA concentrations than those predicted with the older generation of models. The resulting PMCAMx-2008 was applied in Mexico City Metropolitan Area (MCMA for approximately a week during April 2003 during a period of very low regional biomass burning impact. The emission inventory, which uses as a starting point the MCMA 2004 official inventory, is modified and the primary organic aerosol (POA emissions are distributed by volatility based on dilution experiments. The predicted organic aerosol (OA concentrations peak in the center of Mexico City, reaching values above 40 μg m−3. The model predictions are compared with the results of the Positive Matrix Factorization (PMF analysis of the Aerosol Mass Spectrometry (AMS observations. The model reproduces both Hydrocarbon-like Organic Aerosol (HOA and Oxygenated Organic Aerosol (OOA concentrations and diurnal profiles. The small OA underprediction during the rush-hour periods and overprediction in the afternoon suggest potential improvements to the description of fresh primary organic emissions and the formation of the oxygenated organic aerosols, respectively, although they may also be due to errors in the simulation of dispersion and vertical mixing. However, the AMS OOA data are not specific enough to prove that the model reproduces the organic aerosol

    The empirical exploration of mental health problems among bisexual Latino men is scarce. Bisexual men experience stress because of their non-conforming sexuality from multiple-sources. In this study we focus on the family and work environments. We conducted a mixed-methods study to examine the impacts of these social environments among behavioral bisexual Latino men in New York City (N = 142). Using the Brief Symptom Inventory we measured stress, depression, and anxiety, and used specific scales to measure familial and work social environmental stress factors. We also measured four cultural factors to assess their potential influence on our hypothesized stressors. To test our hypothesis we used linear regression with stress, depression and anxiety as the primary outcome variables. Our results indicated that bisexual Latino men experienced negative mental health outcomes due to pressures in their familial and work environments. Stress was the strongest predictor of anxiety and depression among the men in the study. After taking stress into account, familial factors were stronger predictors of negative mental health outcomes than work factors. Cultural factors such as acculturation and length of living in the United States were not associated with negative mental health outcomes in our sample. Our findings suggest the importance of addressing stress, anxiety and depression among behaviorally bisexual men, and suggest that addressing family-based stressors is critical for this population. This research should inform future studies addressing this underserved population and provide mental health providers with a foundation for working with bisexual Latino men.

  2. Site-specific Microzonation Study in Delhi Metropolitan City by 2-D Modelling of SH and P-SV Waves

    Parvez, Imtiyaz A.; Vaccari, F.; Panza, G. F.

    Delhi - the capital of India lies on a severe earthquake hazard threat not only from local earthquakes but also from Himalayan events just 200-250 km apart. The seismic ground motion in a part of Delhi City is computed with a hybrid technique based on the modal summation and the finite-difference scheme for site-specific strong ground motion modelling. Complete realistic SH and #E5/E5#-SV wave seismograms are computed along two geological cross sections, (1) north-south, from Inter State Bus Terminal (ISBT) to Sewanagar and (2) east-west, from Tilak Bridge to Punjabi Bagh. Two real earthquake sources of July 15, 1720 (MMI=IX, M=7.4) and August 27, 1960 (M=6.0) have been used in modelling. The response spectra ratio (RSR), i.e. the response spectra computed from the signals synthesized along the laterally varying section and normalized by the response spectra computed from the corresponding signals, synthesized for the bedrock reference regional model, have been determined. As expected, the sedimentary cover causes an increase of the signal amplitude, particularly in the radial and transverse components. To further check the site-effects, we reversed the source location to the other side of the cross section and recomputed the site amplifications. There are only a few sites where a large amplification is invariant with respect to the two source locations considered. The RSR ranges between 5 to 10 in the frequency range from 2.8 to 3.7 Hz for the radial and transverse components of motion along the NS cross section. Along the EW cross section RSR varies between 3.5 to 7.5 in the frequency range from 3.5 to 4.1 Hz. The amplification of the vertical component is considerable at high frequency (>4 Hz.) whereas it is negligible in lower frequency range.

    A survey was carried out to measure commuters' exposure to PM 2.5, CO, benzene, and the chemical composition of PM 2.5 on different routes and modes of transport in Mexico City. PM 2.5 ( n=62), CO ( n=54) and benzene ( n=22) are presented from morning (6:30-9:30 a.m.) and evening (17:30-20:30) rush hours on minibuses, buses and Metro (underground or subway system). Three routes were selected from a previous commuters' exposure study covering some of the most important thoroughfares of the valley. For PM 2.5, mass concentration was determined for all the samples. Nitrates, sulphates, inorganic elements and carbon fraction were analysed. CO was sampled using electrochemical sensors and 6-l canisters with flow controller devices were used to collect integrated samples for benzene. Minibuses had a slightly higher geometric mean PM 2.5 concentration in the morning than other modes of transport, but the ranking of geometric mean PM 2.5 by mode of transport is opposite in the evening and the variability within modes is approximately double the difference between modes. The highest single measurement was a concentration of 137 μg m -3 on a bus during an evening rush hour. The main component identified in PM 2.5 was carbon. Carbon monoxide levels in this study were approximately 3 times lower than those found in a commuter exposure study conducted in 1991. A strong association was shown between wind speed and PM 2.5 exposure in minibuses ( r2=0.50) and buses ( r2=0.54). The relationship between wind speed and CO exposure was strong only in minibuses ( r2=0.52).

    Black carbon emitted from freight, public transport, and heavy duty trucks sources is linked with adverse effects on human health. In addition, the control of emissions of black carbon, an important short-lived climate forcing agent (SLCF), has recently been considered as one of the key strategies for mitigating regional near-term climate change. Despite the availability of new emissions control technologies for reducing emissions from diesel-powered mobile sources, their introduction is still not widespread in many urban areas and there is a need to characterize real-world emission rates of black carbon from this key source. The emissions of black carbon, organic carbon, and other gaseous and particle pollutants from diesel-powered mobile sources in Mexico were characterized by deploying a mobile laboratory equipped with real-time instrumentation in Mexico City as part of the SLCFs-Mexico 2013 project. From February 25-28 of 2013 the emissions from selected diesel-powered vehicles were measured in both controlled experiments and real-world on-road driving conditions. Sampled vehicles had several emissions levels technologies, including: EPA98, EPA03, EPA04, EURO3-5, and Hybrid. All vehicles were sampled using diesel fuel and several vehicles were measured using both diesel and biodiesel fuels. Additional measurements included the use of a remote sensing unit for the co-sampling of all tested vehicles, and the installation and operation of a Portable Emissions Measurements System (PEMS) for the measurement of emissions from a test vehicle. We will present inter-comparisons of the emission factors obtained among the various vehicle technologies that were sampled during the experiment as well as the inter-comparison of results from the various sampling platforms. The results can be used to

    A study is performed on the impact that the introduction of the electric vehicle (EV) would have in the environmental pollution of the metropolitan area of Mexico City (MAMC) for different penetration scenarios of this technology and the costs of the electric vehicle is analyzed and compared with its counterpart, the gasoline vehicle. The associated emissions of a fleet formed of EV and internal combustion engine vehicles (ICEV) were determined and the emissions reduction of the contaminants considered in the period 1995-2010 produced was analyzed. It was found that the introduction of EV could importantly reduce the carbon monoxide, methane and carbon dioxide and marginally the nitrogen oxides. It was determined that if the EV is massively produced its total cost for its entire useful life would be comparable to the cost of the ICEV. [Espanol] Se realiza un estudio sobre el impacto que tendria la introduccion de vehiculos electricos (VE) en la contaminacion ambiental del area metropolitana de la ciudad de Mexico (AMCM) para diferentes escenarios de penetracion de esta tecnologia y se analiza el costo de los vehiculos electricos en comparacion con su contraparte de gasolina. Se determinaron las emisiones asociadas a una flota compuesta de VE y vehiculos con motor de combustion interna (VMCI) y se analizo la reduccion que producia en las emisiones de los diferentes contaminantes considerados en el periodo 1995-2010. Se encontro que la introduccion de VE podria reducir de manera importante las emisiones de monoxido de carbono, metano y dioxido de carbono y marginalmente las de oxido de nitrogeno. Se determino que si los VE son producidos masivamente su costo total para toda su vida util seria comparable al correspondiente al de los VMCI.

    In the present days, increasing trend of eating disorders are noticed among college students (both male and female) which can disturb their overall physiological and health status. It is more prevalent in metropolitan cities, like Kolkata. But, the existing literature about the physiological and nutritional status of the undergraduate college students of Kolkata is insufficient. Thus, the objective of this small-scale cross-sectional study is to report and compare the prevalence of malnutrition (both obesity and undernutrition) among undergraduate male and female college students of Kolkata, based on body mass index (BMI) and some direct and derived anthropometric measures describing the body composition of the subjects. This cross-sectional study conducted in October-December 2011. The present investigation was carried out in randomly selected male (mean age 20.9 [2.25]) and female college students (mean age 20.3 [2.34]) of Kolkata. A total of 100 students of different colleges has participated, having the age of 18-22 years. Measures included a total of 24 variables which included thirteen direct anthropometric measures and 11 derived variables. Analysis of collected data showed significantly higher BMI, fat mass, body adiposity index, but, lower waist-to-hip ratio, conicity index in female students. Anthropometric data also showed lower waist circumference and abdominal extension in female college students. Conversely, male students showed a higher fat free mass (FFM), mid-upper arm circumference (MUAC) and thigh circumferences (TCs). Based on the findings of the present study, it can be reported that higher body fat distribution and increased propensity of being overweight/obese was observed in female students, though they have shown lower abdominal fat distribution, which is a cue of female physical attractiveness. However, male students are found to have a higher FFM, MUAC and TCs, which is the indicator of strength and energy.

    The city of Wichita, Kansas uses the Equus Beds aquifer, one of two sources, for municipal water supply. To meet future water needs, plans for artificial recharge of the aquifer have been implemented in several phases. Phase I of the Equus Beds Aquifer Storage and Recovery (ASR) Program began with injection of water from the Little Arkansas River into the aquifer for storage and subsequent recovery in 2006. Construction of a river intake structure and surface-water treatment plant began as implementation of Phase II of the Equus Beds ASR Program in 2010. An important aspect of the ASR Program is the monitoring of water quality and the effects of recharge activities on stream conditions. Physical, chemical, and biological data provide the basis for an integrated assessment of stream quality. This report describes protocols for collecting streamflow, water-quality, streambed-sediment, periphyton, macroinvertebrate, fish, and habitat data as part of the city of Wichita's hydrobiological monitoring program (HBMP). Following consistent and reliable methods for data collection and processing is imperative for the long-term success of the monitoring program.

    The Community Multiscale Air Quality Model (CMAQ) with the SAPRC-99 gas phase photochemical mechanism and the AERO5 aerosol module was applied to model gases and particulate matter (PM) concentrations in the Mexico City Metropolitan Zone (MCMZ) and the surrounding regions for March 2006 using the official 2006 emission inventories, along with emissions from biogenic sources, biomass burning, windblown dust, the Tula Industrial Complex and the Popocatépetl volcano. The base case model was capable of reproducing the observed hourly concentrations of O3 and attaining CO, NO2 and NOx performance similar to previous modeling studies. Although the base case model performance of hourly PM2.5 and PM10 meets the model performance criteria, under-prediction of high PM2.5 concentrations in late morning indicates that secondary PM, such as sulfate and secondary organic aerosol (SOA), might be under-predicted. Several potential pathways to increase SOA and secondary sulfate were investigated, including Stabilized Criegee Intermediates (SCIs) from ozonolysis reactions of unsaturated hydrocarbons and their reactions with SO2, the reactive uptake processes of SO2, glyoxal and methylglyoxal on particle surface and higher SOA formation due to higher mass yields of aromatic SOA precursors. Averaging over the entire episode, the glyoxal and methylglyoxal reactive uptake and higher aromatics SOA yields contribute to ∼0.9 μg m-3 and ∼1.25 μg m-3 of SOA, respectively. Episode average SOA in the MCMZ reaches ∼3 μg m-3. The SCI pathway increases PM2.5 sulfate by 0.2-0.4 μg m-3 or approximately 10-15%. The relative amount of sulfate increase due to SCI agrees with previous studies in summer eastern US. Surface SO2 uptake significantly increases sulfate concentration in MCMZ by 1-3 μg m-3 or approximately 50-60%. The higher SOA and sulfate leads to improved PM2.5 and PM10 model performance.

    Full Text Available A field study was carried out from 2003 to 2004 with the aim to develop the PM2.5 emission source profiles from light-duty gasoline and heavy-duty diesel vehicles, as well as emission source profiles from waste incineration, wood burning, LP gas combustion, and meat broiling. Over 25 chemical species were quantified from the fine particles emitted by the different combustion sources investigated, including organic and elemental carbon, ions, and elements. The OC/TC ratio found in the different PM2.5 profiles was dissimilar as well as the sulfate, nitrate, ammonium, soil species, and trace element content. Consequently, these combustion emission profiles could be used in source reconciliation studies for fine particles.

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

    Full Text Available Seoul is transforming into a global city that is competitive with many of the most notable cities in the world such as Tokyo, New York, and London. Seoul's metropolitan governance structure is uniquely suited to the Korean peninsula and has been able to be dynamic in order to adapt to political changes the country has experienced. This article examines the initiatives behind metropolitan governance reforms in Seoul and the factors that play an important role in influencing the current governance structure. The Seoul Metropolitan Government (SMG is set on improving the lives of citizens and ensuring they are happy with their city through transparency, accountability, efficiency, and effectiveness of government among other things. This region has become a strong contributor to the economic growth of the county and helped to create opportunities to attract and retain businesses, implement innovative investment projects and develop a talented workforce. Amongst other reasons, Seoul's solid fiscal system has allowed the city to build the necessary organizational capacity for SMG as well. Additionally, Seoul citizens enjoy a good quality of life because of the educational options, employment opportunities, housing spaces, leisure activities, and cultural experiences found in the city. There are still some challenges ahead but Seoul realizes the importance of civic participation for capacity building and sustainability. One of Seoul's strategies to promoting sustainable living within the city is its ability to engage the public. By promoting citizen participation and feedback, Seoul feels that it will gain new perceptivities during the policy decision-making process. The city's current governance methods continue to succeed because the leaders at SMG understand what is essential to executing successful governance reform: citizens.

    Anthropogenic air pollution is an increasingly serious problem for public health, agriculture, and global climate. Organic material (OM) contributes ~ 20-50% to the total fine aerosol mass at continental mid-latitudes. Although OM accounts for a large fraction of PM2.5 concentration worldwide, the contributions of primary and secondary organic aerosol have been difficult to quantify. In this study, new primary and secondary organic aerosol modules were added to PMCAMx, a three dimensional chemical transport model (Gaydos et al., 2007), for use with the SAPRC99 chemistry mechanism (Carter, 2000; ENVIRON, 2006) based on recent smog chamber studies (Robinson et al., 2007). The new modeling framework is based on the volatility basis-set approach (Lane et al., 2007): both primary and secondary organic components are assumed to be semivolatile and photochemically reactive and are distributed in logarithmically spaced volatility bins. The emission inventory, which uses as starting point the MCMA 2004 official inventory (CAM, 2006), is modified and the primary organic aerosol (POA) emissions are distributed by volatility based on dilution experiments (Robinson et al., 2007). Sensitivity tests where POA is considered as nonvolatile and POA and SOA as chemically reactive are also described. In all cases PMCAMx is applied in the Mexico City Metropolitan Area during March 2006. The modeling domain covers a 180x180x6 km region in the MCMA with 3x3 km grid resolution. The model predictions are compared with Aerodyne's Aerosol Mass Spectrometry (AMS) observations from the MILAGRO Campaign. References Robinson, A. L.; Donahue, N. M.; Shrivastava, M. K.; Weitkamp, E.

    Increased fossil fuel consumption and biomass burning are contributing to significantly larger emissions of black carbon (BC) aerosols to the atmosphere. Together with organic carbon (OC), BC is a major constituent of fine particulate matter in urban air, contributes to haze and has been linked to a broad array of adverse health effects. Black carbon's high light absorption capacity and role in key (in-)direct climate feedbacks also lead to a range of impacts in the Earth system (e.g. warming, accelerated snow melt, changes in cloud formation). Recent work suggests that regulating BC emissions can play an important role in improving regional air quality and reducing future climate warming. However, BC's atmospheric transport pathways, lifetime and magnitudes of emissions by sector and region, particularly emissions from large urban centers, remain poorly constrained by measurements. Contributions of fossil and modern sources to the carbonaceous aerosol pool (corresponding mainly to traffic/industrial and biomass-burning/biogenic sources, respectively) can be quantified unambiguously by measuring the aerosol radiocarbon (14C) content. However, accurate 14C-based source apportionment requires the physical isolation of BC and OC, and minimal sample contamination with extraneous carbon or from OC charring. Compound class-specific 14C analysis of BC remains challenging due to very small sample sizes (5-15 ug C). Therefore, most studies to date have only analyzed the 14C content of the total organic carbonaceous aerosol fraction. Here, we present time-series 14C data of BC and OC from the Los Angeles (LA) metropolitan area in California - one of two megacities in the United States - and from Salt Lake City (SLC), UT. In the LA area, we analyzed 48h-PM10 samples near the LA port throughout 2007 and 2008 (with the exception of summer). We also collected monthly-PM2.5 samples at the University of California - Irvine, with shorter sampling periods during regional wildfire

    Because of the importance of information on the concentration and speciation of Volatile Organic Compounds (VOC) in the atmosphere for the development of regulatory programs or emission control, is necessary to determine the type and the concentrations of reactive and toxic VOC in atmospheric air. The aim of this study is to determine the speciation and quantification of VOC in the atmospheric air of the Mexico City Metropolitan Area (MCMA), from samples obtained in November-December 2011 (cold-dry) and March-April (warm-dry). This study presents the results of characterization of VOC in ambient air in the MCMA conducted during 2011-2012. Sampling of VOC was done in two sampling campaigns: from November 17th to December 11th, 2011, and March 1st to April 6th, 2012 through collection of ambient air each six days in six liters stainless steel SUMMA canisters of 24 hours integrated samples, in three sites (Merced: commercial area with vehicular sources, Pedregal: residential area with vehicular sources and San Agustin: industrial sources with heavy traffic), in the MCMA. The analysis of samples was carried out with two chromatographic systems: 1) method equivalent to the EPA's Method TO-14, and 2) GC/MSD coupled to a preconcentrator ENTECH, for the analysis of the compounds listed in EPA method TO15. It was investigated the concentration of 111 volatile organic compounds, (ozone precursors and toxic compounds). It was found that concentrations of 23 species, constitute 80% of the total VOC concentration tested: ethane, propane, isobutane, n-butane, n-pentane, n-hexane, isopentane, methylcyclopentane, ethylene, propylene, acetylene, benzene, toluene, ethylbenzene, m/p-xylene, o-xylene, 1,2,4-trimethylbenzene, ethyl and isopropyl alcohols, acetone, 2-butanone, MTBE and ethyl acetate. Both in 2011 and 2012, the highest concentrations measured in the three sites were for compounds associated with the combustion of LPG gas: propane, n-butane. The highest concentrations of

    Background The last two decades have seen a growing trend towards the research of voting behavior in post-communist countries. Urban sociology theorists state that not only space structures influence political participation, but also space structures are changing under the influence of global, local, and individual factors. The growing role played by information in the globalised world has accelerated the paradigm shift in urban sociology: from central place model (based on urban-rural distinction and on monocentric metropolitan areas) to network society (based on space of flows and polycentric metropolitan areas). However, recent studies have mainly focused on countries with solid democracies, rather than on former communist countries. The present study aims to analyze the extent to which a new emerging spatial structure can be envisaged within a metropolitan area of Romania and its consequences for the political dimensions of social capital. Methods The Transilvania University Ethics Commission approved this study (S1 Aprouval). The research is based upon individual and aggregate empirical data, collected from the areas adjacent to the core city in Brașov metropolitan area. Individual data has been collected during October 2012, using the oral survey technique (S1 Survey), based on a standardized questionnaire (stratified simple random sample, N = 600). The National Institute of Statistics and the Electoral Register provided the aggregate data per locality. Unvaried and multivariate analyses (hierarchical regression method) were conducted based on these data. Results Some dimensions of urbanism, identified as predictors of the political dimensions of social capital, suggest that the area under analysis has a predominantly monocentric character, where the rural-urban distinction continues to remain relevant. There are also arguments favoring the dissolution of the rural-urban distinction and the emergence of polycentric spatial structures. The presence of some

    Kansas Newman College`s investigate laboratory approach and its partnership with local industries has been motivating precollege students into science since 1990. The Vulcan Chemical Company in Wichita supported our Investigative Summer Science Program for high school juniors where we make science fun and exciting through exploration and testing of ideas, broaden their scientific interests, foster independent scholarship, and with active involvement of community scientists, make them aware of career opportunities and challenges in sciences. Upon completion, 80% to 94% of the participants became interested in pursuing science in college. Our second approach has been to encourage pre-college faculty to have their students present science projects at the annual meeting of Kansas Junior Academy of Science. The Metropolitan Life Foundation has been underwriting all the expenses for promoting participation and hosting of the annual meeting since 1987. The number of science projects/papers has increased from 11 in 1987 to 43 in 1993.

  19. Metropolitan Lima: area profile.

    1986-11-01

    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

    The Equus Beds aquifer in south-central Kansas is a primary water-supply source for the city of Wichita. Water-level declines because of groundwater pumping for municipal and irrigation needs as well as sporadic drought conditions have caused concern about the adequacy of the Equus Beds aquifer as a future water supply for Wichita. In March 2006, the city of Wichita began construction of the Equus Beds Aquifer Storage and Recovery project, a plan to artificially recharge the aquifer with excess water from the Little Arkansas River. Artificial recharge will raise groundwater levels, increase storage volume in the aquifer, and deter or slow down a plume of chloride brine approaching the Wichita well field from the Burrton, Kansas area caused by oil production activities in the 1930s. Another source of high chloride water to the aquifer is the Arkansas River. This study was prepared in cooperation with the city of Wichita as part of the Equus Beds Aquifer Storage and Recovery project. Chloride transport in the Equus Beds aquifer was simulated between the Arkansas and Little Arkansas Rivers near the Wichita well field. Chloride transport was simulated for the Equus Beds aquifer using SEAWAT, a computer program that combines the groundwater-flow model MODFLOW-2000 and the solute-transport model MT3DMS. The chloride-transport model was used to simulate the period from 1990 through 2008 and the effects of five well pumping scenarios and one artificial recharge scenario. The chloride distribution in the aquifer for the beginning of 1990 was interpolated from groundwater samples from around that time, and the chloride concentrations in rivers for the study period were interpolated from surface water samples. Five well-pumping scenarios and one artificial-recharge scenario were assessed for their effects on simulated chloride transport and water levels in and around the Wichita well field. The scenarios were: (1) existing 1990 through 2008 pumping conditions, to serve as a

    This project addresses both fundamental and applied research problems that will help with problems defined by the DOE “20% Wind by 2030 Report”. In particular, this work focuses on increasing the capacity of small or community wind generation capabilities that would be operated in a distributed generation approach. A consortium (KWEC – Kansas Wind Energy Consortium) of researchers from Kansas State University and Wichita State University aims to dramatically increase the penetration of wind energy via distributed wind power generation. We believe distributed generation through wind power will play a critical role in the ability to reach and extend the renewable energy production targets set by the Department of Energy. KWEC aims to find technical and economic solutions to enable widespread implementation of distributed renewable energy resources that would apply to wind.

    2008-12-01

    Full Text Available Within the contexts of globalization and the Atlantic Forest ecoregion, I present a multiscale analysis of anthropogenic landscape dynamics in the Florianópolis city-region, Santa Catarina, southern Brazil. Drawing on field research conducted between 2000 and 2004 and a review of the literature, I examined Brazilian demographic and agricultural census data for the period of 1970 to 1995-1996. I hypothesized that economic restructuring, new institutional arrangements, and the valuation of environmental amenities and ecosystem services have contributed to forest recovery trends and thus a forest transition in the city-region. My results indicate that along with rapid urbanization, in-migration, socioeconomic polarization, and segregation, the city-region has experienced the contraction of private agricultural land area, expansion of protected areas, recovery of forests, and conversion of coastal plain ecosystems to built environments. Future analyses of forest transition dynamics should consider the spatial configurations of socioeconomic inequality in city-regions.

    The Kansas Wind Working Group (WWG) is a 33-member group announced by former Governor Kathleen Sebelius on Jan. 7, 2008. Formed through Executive Order 08-01, the WWG will educate stakeholder groups with the current information on wind energy markets, technologies, economics, policies, prospects and issues. Governor Mark Parkinson serves as chair of the Kansas Wind Working Group. The group has been instrumental in focusing on the elements of government and coordinating government and private sector efforts in wind energy development. Those efforts have moved Kansas from 364 MW of wind three years ago to over 1000 MW today. Further, the Wind Working Group was instrumental in fleshing out issues such as a state RES and net metering, fundamental parts of HB 2369 that was passed and is now law in Kansas. This represents the first mandatory RES and net metering in Kansas history.

    The paper describes the Galatia meteorite found August 1971 approximately 7 km ENE of Galatia, Barton County, Kansas (98 deg 53 min W, 38 deg 39.5 min N). The single stone weighed 23.9 kg and is partially weathered. Olivine (Fa 24.9) and pyroxene (Fs 20.9) compositions indicate L-group classification, and textural observations indicate that the stone is of petrologic type 6. While Galatia is similar in many respects to the Otis L6 chondrite found 20 miles to the west, Galatia does not have the brecciated structure of Otis and is therefore not part of the same fall.

    Metropolitans are a result of fast economic development in China. Many metropolitans have emerged in the eastern part of China. Earthquake disasters in metropolitans are more complicated and serious than those in a smaller city, and the impact of earthquake disaster on the economy and society is large. The characteristics of earthquake disasters and countermeasures to protect against and mitigate disaster in the metropolitan, as well as some key research fields in the earthquake disaster protection and mitigation, are discussed.

    2-(4-Morpholinyl) benzothiazole (24MoBT) and N-cyclohexyl-2-benzothiazolamine (NCBA), which are present in automobile tires, are impurities of the vulcanisation accelerators OBS and CBS, respectively, as defined by the Japan Industrial Standard. To assess 24MoBT and NCBA as markers to trace the usage patterns of OBS and CBS in developing countries, urban dusts were collected from five representative cities of China and India for the analysis of 24MoBT and NCBA. The concentrations in these dust samples were found to be within the range of 3.40-151 ng g-1 for 24MoBT and nd-56.9 ng g-1 for NCBA. The higher levels of 24MoBT may indicate that the traditional accelerator OBS is still used in vehicle tires, whereas the relatively lower contents of NCBA are mainly related to the lesser use of CBS tires. The individual fractions of 24MoBT and NCBA in BTs (24MoBT + NCBA) are compared among cities, and the results show that the fraction sequence is consistent with the number of vehicles and the cities' economic development. This study indicates not only that 24MoBT is presently more suitable for tracing tire wear emissions than NCBA in China but also that there is a potential to assess the impact of traffic sources on urban environments using BTs.

    Traffic jam and air pollution by automobiles are currently getting severe in the Mexico Metropolitan Area. Trolley buses were introduced for improving the environment more than ten years ago. Vehicles become too old for use, and their energy efficiency is low. In this project, 200 highly energy-efficient trolley buses are introduced to replace old inefficient trolley buses, which results in the improved traffic convenience in the City and enhanced energy efficiency. The new energy-efficient trolley buses are made of energy-efficient control VVVF inverters produced and exported by MELCO (Mitsubishi Electric Corporation), energy-efficient motors by MELMEX (Mitsubishi Electric Corporation, Mexico), and bodies by MASA which is a major manufacturer of bus bodies. The objective of this research is to analyze the background of introduction of new energy-efficient trolley buses and the effects of the present project. The results of analysis are going to be utilized for future promotion of the Joint Implementation and Clean Development Mechanism. 30 refs., 30 figs., 24 tabs.

    Full Text Available A mobile laboratory was used to measure on-road vehicle emission ratios during the MCMA-2003 field campaign held during the spring of 2003 in the Mexico City Metropolitan Area (MCMA. The measured emission ratios represent a sample of emissions of in-use vehicles under real world driving conditions for the MCMA. From the relative amounts of NOx and selected VOC's sampled, the results indicate that the technique is capable of differentiating among vehicle categories and fuel type in real world driving conditions. Emission ratios for NOx, NOy, NH3, H2CO, CH3CHO, and other selected volatile organic compounds (VOCs are presented for chase sampled vehicles and fleet averaged emissions. Results indicate that colectivos, particularly CNG-powered colectivos, are potentially significant contributors of NOx and aldehydes in the MCMA. Similarly, ratios of selected VOCs and NOy showed a strong dependence on traffic mode. These results are compared with the vehicle emissions inventory for the MCMA, other vehicle emissions measurements in the MCMA, and measurements of on-road emissions in US cities. Our estimates for motor vehicle emissions of benzene, toluene, formaldehyde, and acetaldehyde in the MCMA indicate these species are present in concentrations higher than previously reported. The high motor vehicle aldehyde emissions may have an impact on the photochemistry of urban areas.

    Full Text Available From the perspective of urbanism, the beginning of the twenty-first century in the metropolitan region of Buenos Aires has been characterized for the emergence of large-scale projects developed by private actors. Among them stand out private cities and commercial and services areas, called new centralities. Both urban designs are in close connection and require effective mobility conditions for its concretion. The intervention of private agents has impacted in the territorial transformations, creating a "parallel urban system" in the region, oriented towards attracting residents with a high socio-economic status. However, the traditional network of cities has not disappeared and, with the juxtaposition of this new system of private urbanism, it deepened the conditions of spatial fragmentation and social segregation. Desde la perspectiva del urbanismo, el comienzo del siglo XXI se caracteriza por la aparición en la región metropolitana de Buenos Aires, de proyectos de gran envergadura desarrollados por agentes privados. Entre ellos sobresalen las ciudades privadas y las áreas comerciales y de servicios, denominadas nuevas centralidades. Ambos diseños urbanos se mantienen en estrecha relación y requieren de eficaces condiciones de movilidad para su concreción y para su exitoso funcionamiento. La intervención de los agentes privados ha impactado en las transformaciones territoriales, creando un “sistema urbano paralelo” en la región, orientado a la captación de residentes con un alto nivel socio-económico. No obstante, la red de ciudades pre-existente no ha desaparecido y con la yuxtaposición de este nuevo sistema de urbanismo privado, se profundizan las condiciones de fragmentación espacial y de segregación social.

    Amoebiasis, caused by Entamoeba histolytica , has a worldwide distribution and is of public health significance in many developing countries. It has a fecal-oral transmission cycle and is most prevalent in developing countries in regions where substandard sanitary conditions exist due to poverty. Little is known about the epidemiology of E. histolytica infection and its presence in different socioeconomic communities in developing countries. We undertook the present study in the city of Lahore, Pakistan, and our prediction was that the prevalence of E. histolytica -like cysts and E. histolytica stool antigen would be lower in patients from upper socioeconomic levels than in individuals from middle or lower socioeconomic levels. We investigated the prevalence of E. histolytica in humans from 3 socioeconomic communities in territories of Lahore, Pakistan. Six hundred fecal samples were collected and examined using both microscopy (triple fecal test) to detect cysts of E. histolytica -like amoeba and ELISA (stool antigen ELISA) to demonstrate diagnostic stool antigens of E. histolytica . Samples were from individuals living under conditions deemed to be upper socioeconomic class (n = 287), middle socioeconomic class (n = 172), and lower socioeconomic class (n = 141). The total prevalence of positive samples was 22.5% (135/600) by triple test and 16.8% (101/600) by stool antigen ELISA in the 600 fecal samples. Statistically, significant (P histolytica antigens than were samples from the other 3 age groups, and that prevalence was significantly higher (P < 0.05) in the summer than in the other 3 seasons. These results highlight the importance of surveillance of this relatively ignored pathogen in this developing metropolitan city in Pakistan.

Emission ratios for NOx, NOy, NH3, H2CO, CH3CHO, and other selected volatile organic compounds (VOCs) are presented for chase sampled vehicles in the form of frequency distributions as well as estimates for the fleet averaged emissions. Our measurements of emission ratios for both CNG and gasoline powered "colectivos" (public transportation buses that are intensively used in the MCMA) indicate that - in a mole per mole basis - have significantly larger NOx and aldehydes emissions ratios as compared to other sampled vehicles in the MCMA. Similarly, ratios of selected VOCs and NOy showed a strong dependence on traffic mode. These results are compared with the vehicle emissions inventory for the MCMA, other vehicle emissions measurements in the MCMA, and measurements of on-road emissions in U.S. cities. We estimate NOx emissions as 100 600±29 200 metric tons per year for light duty gasoline vehicles in the MCMA for 2003. According to these results, annual NOx emissions estimated in the emissions inventory for this category are within the range of our estimated NOx annual emissions. Our estimates for motor vehicle emissions of benzene, toluene, formaldehyde, and acetaldehyde in the MCMA indicate these species are present in concentrations higher than previously reported. The high motor vehicle aldehyde emissions may have an impact on the photochemistry of urban areas.

  16. Investigation of Integrated Subsurface Processing of Landfill Gas and Carbon Sequestration, Johnson County, Kansas

    2007-03-31

    The Johnson County Landfill in Shawnee, KS is operated by Deffenbaugh Industries and serves much of metropolitan Kansas City. Refuse, which is dumped in large plastic-underlined trash cells covering several acres, is covered over with shale shortly after burial. The landfill waste, once it fills the cell, is then drilled by Kansas City LFG, so that the gas generated by anaerobic decomposition of the refuse can be harvested. Production of raw landfill gas from the Johnson County landfill comes from 150 wells. Daily production is approximately 2.2 to 2.5 mmcf, of which approximately 50% is methane and 50% is carbon dioxide and NMVOCs (non-methane volatile organic compounds). Heating value is approximately 550 BTU/scf. A upgrading plant, utilizing an amine process, rejects the carbon dioxide and NMVOCs, and upgrades the gas to pipeline quality (i.e., nominally a heating value >950 BTU/scf). The gas is sold to a pipeline adjacent to the landfill. With coal-bearing strata underlying the landfill, and carbon dioxide a major effluent gas derived from the upgrading process, the Johnson County Landfill is potentially an ideal setting to study the feasibility of injecting the effluent gas in the coals for both enhanced coalbed methane recovery and carbon sequestration. To these ends, coals below the landfill were cored and then were analyzed for their thickness and sorbed gas content, which ranged up to 79 scf/ton. Assuming 1 1/2 square miles of land (960 acres) at the Johnson County Landfill can be utilized for coalbed and shale gas recovery, the total amount of in-place gas calculates to 946,200 mcf, or 946.2 mmcf, or 0.95 bcf (i.e., 985.6 mcf/acre X 960 acres). Assuming that carbon dioxide can be imbibed by the coals and shales on a 2:1 ratio compared to the gas that was originally present, then 1682 to 1720 days (4.6 to 4.7 years) of landfill carbon dioxide production can be sequestered by the coals and shales immediately under the landfill.

    In recent decades, studies in the field of public health have increasingly focused on social determinants that affect the health-illness process. The epidemiological perspective considers oral health to be a reflection of socioeconomic and environmental aspects, and it is particularly influenced by the social context. The aim of the present study was to assess the association between the severity of dental caries among adults aged 35 to 44 years and characteristics on the different levels at which the determinants of caries operate (individual, social structure and social context). A home-based, cross-sectional field study was carried out involving a sample of 1,150 adults (35 to 44 years of age) residing in metropolitan Belo Horizonte, Brazil. The DMFT (decayed, missing, filled tooth) index (≥14) was used to determine the severity of dental caries. Bivariate and multivariate analyses were carried out using the Poisson regression model with the level of significance set at 5% (p caries severity. The rate of high-severity caries in the group between 40 and 44 years of age was 1.15-fold (CI: 1.04-1.26) greater than that among those aged 35 to 39 years. A greater prevalence of high caries severity was found among those who frequently visited the dentist (PR = 1.18; CI: 1.07-1.30), those with a lower income (PR = 1.11; CI: 1.01-1.23), those who reported that their neighborhood did not come together in the previous year to petition political leaders for benefits (PR = 1.16; CI: 1.05-1.28) and those who are unable to make decisions (without empowerment) (PR = 1.12; CI: 1.01-1.24). The present study revealed high dental caries severity in adults, which was associated with individual characteristics, health-related behavior and social structure and contextual variables. These findings underscore the importance of considering social determinants involved in the health-illness process when carrying out epidemiological studies on dental caries.

    Accumulation of trace metals (Fe, Mn, Cr, Cu, Ni, Co, Pb, Zn, Cd) were investigated in water, sediment (n=20) along with six fish of diverse feeding guilds (Sillago sihama, Liza parsia, Etroplus suratensis, Oreochromis mossambicus, Arius parkii and Gerres oyena) from the Ennore creek, northern part of Chennai metropolitan megacity, southeast coast of India. Dissolved trace metals (DTMs) in surface water samples and total trace metals (TTMs) in surface sediments (top 0-10cm) indicate that concentration pattern of metals was higher in the discharge point of the river/channels entering the main creek. The maximum mean values of DTMs exhibited the following decreasing order (expressed in µg/L): Fe (1698)>Mn (24)>Zn (14.50)>Pb (13.89)>Ni (6.73)>Cu (3.53)>Co (3.04)>Cr (2.01) whereas the trend is somewhat different in sediments (µgg(-1)): Fe (4300)>Mn (640)>Cr (383)>Zn (155)>Cu (102)>Ni (35)>Pb (32)>Cd (0.51) are mainly due to the industrial complexes right on the banks of the river/channels. Species-specific heterogeneous patterns of tissue metal loads were apparent and the overall metal enrichment exhibited the following decreasing order (expressed in µgg(-1)): Cu (7.33)>Fe (6.53)>Zn (4.91)>Cr (1.67)>Pb (1.33)>Ni (0.44)>Mn (0.43)>Co (0.36)>Cd (0.11). This indicates that metals are absorbed onto the different organs, which is also endorsed by the calculated values of bioaccumulation factor (BAFs) (avg. muscle 117, gill 126, liver 123, intestine 118) in fishes. The high calculated biota sediment accumulation factor (BSAF) (0.437) for the species Arius parkii is considered to be a potential bioindicator in this region. The enrichment of trace metals is also supported by the association of metals in water, sediments and different body organs (muscle, gill, liver, intestine) of fish samples. Comparative studies with other coastal regions indicate considerable enrichment of DTMs & TTMs in sediments as well as in various organs of fish samples. Holistic spatial, temporal

    2013-12-01

    Full Text Available Metropolitan development succeeds chronologically, as well as structurally urban development, this means a new phase in the urban system development through the extension beyond its initial boundaries. Along with the cities’ surrounding areas population growth, especially through emigration from the cities, but as well as through the attraction of population from other localities, the geographical and the administrative boundaries of the cities become inadequate for the definition of the urban agglomerations that emerge. This extension is generated as well by an ample endogenous process of local economic development that is forcing the association of several local communities around an urban center becoming a growth pole in order to develop its level of competitiveness. Metropolitan development represents thus an administrative and economical challenge regarding the management and the coordination of an increased palette of resources.

  7. Estimation of the mass absorption cross section of the organic carbon component of aerosols in the Mexico City Metropolitan Area (MCMA

    2008-05-01

    Full Text Available Data taken from the MCMA-2003 and the 2006 MILAGRO field campaigns are used to examine the absorption of solar radiation by the organic component of aerosols. Using irradiance data from a Multi-Filter Rotating Shadowband Radiometer (MFRSR and an actinic flux spectroradiometer (SR, we derive aerosol single scattering albedo, π0,λ, as a function of wavelength, λ. We find that in the near-UV spectral range (250 to 400 nm π0,λ is much lower compared to π0,λ at 500 nm indicating enhanced absorption in the near-UV range. Absorption by elemental carbon, dust, or gas cannot account for this enhanced absorption leaving the organic part of the aerosol as the only possible absorber. We use data from a surface deployed Aerodyne Aerosol Mass Spectrometer (AMS along with the inferred π0,λ to estimate the Mass Absorption Cross section (MAC for the organic carbon. We find that the MAC is about 10.5 m2/g at 300 nm and falls close to zero at about 500 nm; values that are roughly consistent with other estimates of organic carbon MAC. These MAC values can be considered as "radiatively correct" because when used in radiative transfer calculations the calculated irradiances/actinic fluxes match those measured at the wavelengths considered here. For an illustrative case study described here, we estimate that the light absorption by the "brown" (organic carbonaceous aerosol can add about 40% to the light absorption of black carbon in Mexico City. This contribution will vary depending on the relative abundance of organic carbon relative to black carbon. Furthermore, our analysis indicates that organic aerosol would slow down photochemistry by selectively scavenging the light reaching the ground at those wavelengths that drive photochemical reactions. Finally, satellite retrievals of trace gases that are used to infer emissions currently assume that the MAC of organic carbon is zero. For trace gases that are

  9. The Evolution of Groundwater Management Paradigms in Kansas, USA

    Science.gov (United States)

    Sophocleous, M. A.

    2011-12-01

    The purpose of this presentation is to trace the evolution of key water-related laws and management practices in Kansas, from the enactment of the Kansas Water Resources Appropriation Act of 1945 to the present, in order to highlight the state's efforts to create a more sustainable water future and in hopes that others will benefit from Kansas' experience. The 1945 Act provides the basic framework of water law (prior appropriation) in Kansas. Progression of groundwater management in the state encompasses local ground-water management districts (GMDs) and their water-management programs, minimum-streamflow and TMDL standards, water-use reporting and water metering programs, use of modified safe-yield policies in some GMDs, the subbasin water-resources-management program, the integrated resource planning/Aquifer Storage and Recovery project of the City of Wichita, the Central Kansas Water Bank, enhanced aquifer subunits management, and various water conservation programs. While these have all contributed to the slowing down of declines in groundwater levels in the High Plains aquifer and in associated ecosystems, they have not yet succeeded in halting those declines. Based on the assumption that the different management approaches have to operate easily within the prevailing water rights and law framework to succeed, a number of steps are suggested here that may help further halt the declines of the High Plains aquifer. These include eliminating the "use it or lose it" maxim in the prior-appropriation framework, broadening the definition of "beneficial use," regulating domestic and other "exempt" wells, encouraging voluntary "sharing the shortage" agreements, and determining to what extent water rights may be regulated in the public interest without a compensable "taking." Further necessary measures include determining to what extent water-rights holders might be subjected to reasonable dictates without having the security of their rights altered.

    Full Text Available Carbon neutrality represents one climate strategy adopted by many cities, including the city of Helsinki and the Helsinki metropolitan area in Finland. This study examines initiatives adopted by the Helsinki metropolitan area aimed at reducing energy-related carbon emissions and achieving carbon neutrality through future actions. Various sectorial energy consumption rates per year and carbon emissions from various sectors within the city of Helsinki and the metropolitan area were extracted from an online database and re-calculated (in GWh, MWh/inhabitant and MtCO2e, KtCO2e/inhabitant. We employed a backcasting scenario method to explore the various carbon reduction measures in the Helsinki metropolitan area. About 96% of the emissions produced in the Helsinki metropolitan area are energy-based. District heating represents the primary source of emissions, followed by transportation and electricity consumption, respectively. We also found that accomplishing the carbon reduction strategies of the Helsinki metropolitan area by 2050 remains challenging. Technological advancement for clean and renewable energy sources, smart policies and raising awareness resulting in behavioral changes greatly affect carbon reduction actions. Thus, strong political commitments are also required to formulate and implement stringent climate actions.

    Water quality of streams in Johnson County, Kansas was evaluated from October 2002 through December 2007 in a cooperative study between the U.S. Geological Survey and the Johnson County Stormwater Management Program. Water quality at 42 stream sites, representing urban and rural basins, was characterized by evaluating benthic macroinvertebrates, water (discrete and continuous data), and/or streambed sediment. Point and nonpoint sources and transport were described for water-quality constituents including suspended sediment, dissolved solids and major ions, nutrients (nitrogen and phosphorus), indicator bacteria, pesticides, and organic wastewater and pharmaceutical compounds. The information obtained from this study is being used by city and county officials to develop effective management plans for protecting and improving stream quality. This fact sheet summarizes important results from three comprehensive reports published as part of the study and available on the World Wide Web at http://ks.water.usgs.gov/Kansas/studies/qw/joco/ .

    An enhanced research paradigm is presented to address the spatial and temporal gaps in fine particulate matter (PM2.5) measurements and generate realistic and representative concentration fields for use in epidemiological studies of human exposure to ambient air particulate concentrations. The general approach for research designed to analyze health impacts of exposure to PM2.5 is to use concentration data from the nearest ground-based air quality monitor(s), which typically have missing data on the temporal and spatial scales due to filter sampling schedules and monitor placement, respectively. To circumvent these data gaps, this research project uses a Hierarchical Bayesian Model (HBM) to generate estimates of PM2.5 in areas with and without air quality monitors by combining PM2.5 concentrations measured by monitors, PM2.5 concentration estimates derived from satellite aerosol optical depth (AOD) data, and Community-Multiscale Air Quality (CMAQ) model predictions of PM2.5 concentrations. This methodology represents a substantial step forward in the approach for developing representative PM2.5 concentration datasets to correlate with inpatient hospitalizations and emergency room visits data for asthma and inpatient hospitalizations for myocardial infarction (MI) and heart failure (HF) using case-crossover analysis. There were two key objective of this current study. First was to show that the inputs to the HBM could be expanded to include AOD data in addition to data from PM2.5 monitors and predictions from CMAQ. The second objective was to determine if inclusion of AOD surfaces in HBM model algorithms results in PM2.5 air pollutant concentration surfaces which more accurately predict hospital admittance and emergency room visits for MI, asthma, and HF. This study focuses on the New York City, NY metropolitan and surrounding areas during the 2004-2006 time period, in order to compare the health outcome impacts with those from previous studies and focus on any

    2011-08-01

    A modified Vicsek-Szalay model is introduced. From this, experiments are performed in order to simulate the spatial morphology of the largest metropolitan area of México: a set of clusters formed by the Valle de México metropolitan area (VMMA), Puebla metropolitan area (PMA) and Toluca metropolitan area (TMA). This case is presented in detail and here is called the Central México metropolitan area (CMMA). To verify the effectiveness of our approach we study two other cases; the set of clusters formed by the Monterrey zone (MZ, formed by the Monterrey metropolitan area and the Saltillo City metropolitan area) and the Chihuahua zone (ChZ, formed by the Chihuahua metropolitan area, Delicias City and Cuauthemoc City ), with acceptable results. Besides we compute three different fractal measures for all our areas of interest (AOI). In this paper, we focus on the global feature of these fractal measures in the description of urban geography and obtained local information which normally comes from inner city structures and small scale human decisions. Finally, we verified that the Zipf law is fulfilled by our simulated urban morphologies, so we know that our model follows it. As is normal for actual city size distributions, the CMMA case is presented in detail. We intend to pave the way in the understanding of population spatial distribution in a geographical space.

  18. Unhappy Cities

    Glaeser, Edward L.; Gottlieb, Joshua D.; Ziv, Oren

    2016-01-01

    There are persistent differences in self-reported subjective well-being across US metropolitan areas, and residents of declining cities appear less happy than others. Yet some people continue to move to these areas, and newer residents appear to be as unhappy as longer-term residents. While historical data on happiness are limited, the available facts suggest that cities that are now declining were also unhappy in their more prosperous past. These facts support the view that individuals do not maximize happiness alone but include it in the utility function along with other arguments. People may trade off happiness against other competing objectives. PMID:27546979

    2010-08-01

    The purpose of this study was to investigate the preferences of elected city officials regarding the need for a statewide clean indoor air law and to analyze the content of local smoking ordinances. A survey of elected officials in 57 larger Kansas cities obtained information on the perceived need for statewide legislation, venues to be covered, and motivating factors. Clean indoor air ordinances from all Kansas cities were analyzed by venue. The survey response rate was 190 out of 377 (50.4%) for elected officials. Over 70% of the respondents favored or strongly favored greater restrictions on indoor smoking. Sixty percent favored statewide legislation. Among these, over 80% favored restrictions in health care facilities, theaters, indoor sports arenas (including bowling alleys), restaurants, shopping malls, lobbies, enclosed spaces in outdoor arenas, and hotel/motel rooms. Officials who had never smoked favored a more restrictive approach. Employee and public health concerns were cited as influential by 76%-79% of respondents. Thirty-eight ordinances, covering over half of the state's population, were examined. They varied considerably in their exemptions. Official's attitudes toward smoking regulations were associated with their smoking status. The examination of existing ordinances revealed a piecemeal approach to smoking regulations.

    Carbon tetrachloride contamination in groundwater at Morrill, Kansas, was initially identified in 1985 during statewide testing of public water supply wells for volatile organic compounds (VOCs). High levels of nitrate were also present in the public water supply wells. The city of Morrill is located in Brown County in the northeastern corner of the state, about 7 mi east of Sabetha (Figure 1.1). The population of Morrill as of the 2010 Census was approximately 230 (down from 277 in 2000). All residents of Morrill now obtain their drinking water from the Sabetha municipal water system via a pipeline constructed in 1991. This document reports the findings concerning the groundwater in Morrill.

  11. Monitoring the Increase in Seismicity in South-Central Kansas

    2016-12-01

    There has been a dramatic increase in seismicity in the Midcontinent over the last five years, which appears to be linked to the injection of large volumes of wastewater from oilfield operations. Injection of fluids into deeper formations causes an increase in pore pressure, which can facilitate slip on existing faults oriented optimally to subsurface stress fields. Very little is known about the stresses within the shallow basement in Southern Kansas which has seen an increase in seismicity. The historical average of 21 M>3 earthquakes a year has increased to 188 M>3 reported earthquakes observed in 2011, in the US midcontinent. Earthquake focal mechanisms were analyzed for western Sumner County, south-central Kansas, from May of 2015 to July of 2016. The Kansas Geological Society (KGS) seismometer array in the Wellington Oil Field and the United States Geological Survey (USGS) portable array in southern Kansas were used to locate the earthquakes. These arrays generated a catalog of events from Mw .4 to Mw 3.5. Analyses of focal mechanisms for nearly 200 earthquakes larger than approximately Mw 2.0 were included in the inversion. Earthquakes of this magnitude were recorded on nearly all stations. The larger magnitude events tend to cluster in Northeast-Southwest and Northwest-Southeast lineations. These local, larger earthquakes provide a better understanding of the stresses that are causing the increased seismicity. The stress tensor was calculated for the region to the west of the city of Wellington, KS, in Sumner County. The primary horizontal stress direction is nearly east. This observation is in agreement with well data that estimates the maximum horizontal stress at approximately 75 degrees.

    Full Text Available The integration of cities and their regions into transnational networks has become a key municipal strategy, with the creation of a metropolitan governance structure being seen in this context as a fundamental element. The Szczecin Metropolitan Area constitutes an example of meagre results in intercommunal cooperation in post-socialist East-Central Europe. This has its repercussions on the task of creating cross-border metropolitan governance structures including adjacent German counties, a task which, in turn, may help to overcome development barriers. This becomes apparent particularly in the process of defining joint development objectives as well as an image for the cross-border metropolitan region

    In the next years, Mexico will face the following challenges: to maintain economic, social and urban rates of growth among others, higher than the demographic ones with the purpose of guaranteeing a better quality of life and mitigating gas discharges of green house effect without jeopardizing the development of the country. In an eminently urban country, these goals are made first in local form as it is the case of the metropolitan zone of the city of Mexico City (ZMCM), with different actions to mitigate the effects of the high development that this region has had. The objective is to try to modify the perception that one has had of it at the beginning of the 90's decade when it was denominated by Time magazine (January 1989) as the waiting room of an ecological Hiroshima and as urban gas chamber. The official answer conformed it: the creation of a Network of Atmospheric Monitoring, the implantation of programs like the Pro Air, the Today Does Not Circulate among others. Even with these actions in mind the objective does not glimpse clearly in the short term to reach a development with environmental sustainability. The work premise is to analyze different actions oriented to diminish in a 20% the emissions of polluting agents using clean and renewable energies such as natural gas and solar, among others, without trying to originate radical changes and that can be applied in other cities of the country. In parallel form one sets out to sustain these actions with the present environmental programs and to quantify the sustainability with three indicators (variation of polluting emissions, the level of fossil resources and costs to the health). The development of the investigation is based on the definition of a reference scenario (on the base of the present tendencies) and another alternative scenario having as analysis tool the computational platform denominated ENPEP (Energy and Power Evaluation Program) developed by National Argonne National Laboratory

    2016-04-06

    The Kansas River is a primary source of drinking water for about 800,000 people in northeastern Kansas. Source-water supplies are treated by a combination of chemical and physical processes to remove contaminants before distribution. Advanced notification of changing water-quality conditions and cyanobacteria and associated toxin and taste-and-odor compounds provides drinking-water treatment facilities time to develop and implement adequate treatment strategies. The U.S. Geological Survey (USGS), in cooperation with the Kansas Water Office (funded in part through the Kansas State Water Plan Fund), and the City of Lawrence, the City of Topeka, the City of Olathe, and Johnson County Water One, began a study in July 2012 to develop statistical models at two Kansas River sites located upstream from drinking-water intakes. Continuous water-quality monitors have been operated and discrete-water quality samples have been collected on the Kansas River at Wamego (USGS site number 06887500) and De Soto (USGS site number 06892350) since July 2012. Continuous and discrete water-quality data collected during July 2012 through June 2015 were used to develop statistical models for constituents of interest at the Wamego and De Soto sites. Logistic models to continuously estimate the probability of occurrence above selected thresholds were developed for cyanobacteria, microcystin, and geosmin. Linear regression models to continuously estimate constituent concentrations were developed for major ions, dissolved solids, alkalinity, nutrients (nitrogen and phosphorus species), suspended sediment, indicator bacteria (Escherichia coli, fecal coliform, and enterococci), and actinomycetes bacteria. These models will be used to provide real-time estimates of the probability that cyanobacteria and associated compounds exceed thresholds and of the concentrations of other water-quality constituents in the Kansas River. The models documented in this report are useful for characterizing changes

    Kansas produces both conventional energy (oil, gas, and coal) and nonconventional (coalbed gas, wind, hydropower, nuclear, geothermal, solar, and biofuels) and ranks the 22nd in state energy production in the U.S. Nonrenewable conventional petroleum is the most important energy source with nonrenewable, nonconventional coalbed methane gas becoming increasingly important. Many stratigraphic units produce oil and/or gas somewhere in the state with the exception of the Salina Basin in north-central Kansas. Coalbed methane is produced from shallow wells drilled into the thin coal units in southeastern Kansas. At present, only two surface coal mines are active in southeastern Kansas. Although Kansas has been a major exporter of energy in the past (it ranked first in oil production in 1916), now, it is an energy importer.

    Barnes, Kansas, is a small rural community (population approximately 150) located in Washington County, in north-central Kansas (Figure 1.1). Barnes is located in Section 9, Township 4 South, Range 5 East, at approximate latitude 39°43'0'' north and longitude 96°52'25'' west (USGS 1968). The city lies in a transition zone between the Flint Hills and the glaciated region. The area’s topography consists of gently sloping hills of Pleistocene loess (< 20 ft) overlying a shale unit and interbedded shale, limestone, and siltstone of the Permian Chase Group. Groundwater for the public water supply is obtained from wells PWS2 and PWS3 at reported depths of 155 ft and 160 ft, respectively, located in the northwestern portion of the city. The water is produced from the bedrock aquifer of the Chase Group. Section 2 summarizes the hydrogeologic conceptual site model. This report summarizes findings for groundwater inspection in Barnes.

  1. Air pollution holiday effect in metropolitan Kaohsiung

    2014-12-01

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

  2. The Edgerton Structure: A Possible Meteorite Impact Feature in Eastern Kansas

    Directory of Open Access Journals (Sweden)

    Daniel F. Merriam

    2009-01-01

    Full Text Available Recognized meteorite impact features are relatively rare in the U.S. Midcontinent region, but recently with increased interest and research, the number has increased dramatically. We add another possibility to the growing list, the Edgerton structure in northwestern Miami County, Kansas. The feature is elliptical (∼5.5 × 6.5 km, slightly elongated east-west with radial surface drainage. The feature was first observed on hillshade maps of digitized topography of 7.5 minute quadrangles. Subsequent magnetic profiles show a higher magnetic value in the center of the ellipse with higher values around the edges; this shape is characteristic of an impact feature. Depth to the anomalous body is estimated to be about 1 km, which puts it in the Precambrian crystalline basement under a cover of Paleozoic sediments. There are no deep boreholes in the vicinity and no seismic profiles are available. If it is an impact structure, it will be the second such feature documented in Kansas, the first being the Brenham meteorite crater at Haviland in Kiowa County in southwestern Kansas. It would be older than the other impact structures identified in the Midcontinent—Manson in Iowa, Ames in Oklahoma, Haswell Hole in Colorado, and possibly Belton in Missouri and Merna in Nebraska. There are at least two other prospective impact features in Kansas: the Goddard ring west of Wichita and Garden City ellipse north-west of Garden City.

    Digital flood-inundation maps for a 6.4-mile upper reach of Indian Creek from College Boulevard to the confluence with Tomahawk Creek, a 3.9-mile reach of Tomahawk Creek from 127th Street to the confluence with Indian Creek, and a 1.9-mile lower reach of Indian Creek from the confluence with Tomahawk Creek to just beyond the Kansas/Missouri border at State Line Road in Johnson County, Kansas, were created by the U.S. Geological Survey in cooperation with the city of Overland Park, Kansas. The flood-inundation maps, which can be accessed through the U.S. Geological Survey Flood Inundation Mapping Science Web site at http://water.usgs.gov/osw/flood_inundation/, depict estimates of the areal extent and depth of flooding corresponding to selected water levels (stages) at the U.S. Geological Survey streamgages on Indian Creek at Overland Park, Kansas; Indian Creek at State Line Road, Leawood, Kansas; and Tomahawk Creek near Overland Park, Kansas. Near real time stages at these streamgages may be obtained on the Web from the U.S. Geological Survey National Water Information System at http://waterdata.usgs.gov/nwis or the National Weather Service Advanced Hydrologic Prediction Service at http://water.weather.gov/ahps/, which also forecasts flood hydrographs at these sites.Flood profiles were computed for the stream reaches by means of a one-dimensional step-backwater model. The model was calibrated for each reach by using the most current stage-discharge relations at the streamgages. The hydraulic models were then used to determine 15 water-surface profiles for Indian Creek at Overland Park, Kansas; 17 water-surface profiles for Indian Creek at State Line Road, Leawood, Kansas; and 14 water-surface profiles for Tomahawk Creek near Overland Park, Kansas, for flood stages at 1-foot intervals referenced to the streamgage datum and ranging from bankfull to the next interval above the 0.2-percent annual exceedance probability flood level (500-year recurrence interval).

    2016-08-01

    Uber and similar rideshare services are rapidly dispersing in cities across the United States and beyond. Given the convenience and low cost, Uber has been characterized as a potential countermeasure for reducing the estimated 121 million episodes of drunk driving and the 10,000 resulting traffic fatalities that occur annually in the United States. We exploited differences in the timing of the deployment of Uber in US metropolitan counties from 2005 to 2014 to test the association between the availability of Uber's rideshare services and total, drunk driving-related, and weekend- and holiday-specific traffic fatalities in the 100 most populated metropolitan areas in the United States using negative binomial and Poisson regression models. We found that the deployment of Uber services in a given metropolitan county had no association with the number of subsequent traffic fatalities, whether measured in aggregate or specific to drunk-driving fatalities or fatalities during weekends and holidays.

    This research examines the larger-scale associations between obesity and food environments in metropolitan areas in the United States (US). The US Census County Business Patterns dataset for 2011 was used to construct various indices of food environments for selected metropolitan areas. The numbers of employees engaged in supermarkets, convenience stores, full service restaurants, fast food restaurants, and snack/coffee shops were standardised using the location quotients, and factor analysis was used to produce two uncorrelated factors measuring food environments. Data on obesity were obtained from the 2011 Behavioral Risk Factor Surveillance System. Individual level obesity measures were linked to the metropolitan area level food environment factors. Models were fitted using generalised estimating equations to control for metropolitan area level intra-correlation and individual level sociodemographic characteristics. It was found that adults residing in cities with a large share of supermarket and full-service restaurant workers were less likely to be obese, while adults residing in cities with a large share of convenience store and fast food restaurant workers were more likely to be obese. Supermarkets and full-service restaurant workers are concentrated in the Northeast and West of the US, where obesity prevalence is relatively lower, while convenience stores and fast-food restaurant workers are concentrated in the South and Midwest, where obesity prevalence is relatively higher. The food environment landscapes measured at the metropolitan area level explain the continental-scale patterns of obesity prevalence. The types of food that are readily available and widely served may translate into obesity disparities across metropolitan areas.

    2016-02-01

    Inman, Kansas, is a rural town located in southwest McPherson County, in sections 8, 9, 16, and 17, Township 21 South, Range 4 West (Figure 1.1). There are 1,377 people in 513 households, as of the census of 2010. The Commodity Credit Corporation of the U.S. Department of Agriculture (CCC/USDA), operated a grain storage facility at the southern edge of the city of Inman, Kansas, from 1954 to 1965. During this time, commercial grain fumigants containing carbon tetrachloride were in common use by the grain storage industry to preserve grain in their facilities. In 1997, trace to low levels of carbon tetrachloride (below the maximum contamination level [MCL] of 5.0 μg/L) were detected in three private wells near the former grain storage facility at Inman, as part of a statewide USDA private well sampling program that was implemented by the Kansas Department of Health and Environment (KDHE) near former CCC/USDA facilities. No public water supply wells were identified within 1 mi of the town by the KDHE in 1998. Carbon tetrachloride is the contaminant of primary concern at sites associated with grain storage operations. To determine whether the former CCC/USDA facility at Inman is a potential contaminant source and its possible relationship to the carbon tetrachloride contamination in groundwater, the CCC/USDA agreed to conduct a multi-phase investigation at Inman. The investigation was performed by the Environmental Science Division of Argonne National Laboratory in accordance with the Intergovernmental Agreement between the KDHE and the Farm Service Agency of the USDA.

    Full Text Available Concepts of national and regional innovation systems can serve as an analytical framework forming the empirical base for innovation policy creation. It is possible to distinguish various types of these systems. One of these typologies is based on the assessment of innovation deficiencies. There are three types of regions: metropolitan, peripheral, and old industrial. Metropolitan regions can be characterized by a high level of research, innovation, and patent activity. The aims of this paper are to find relevant indicators that can be used as the basis for defining metropolitan regional innovation systems and using them for the identification of Czech metropolitan regions. The results of the point method combined with the cluster analysis showed that the capital city, Prague, as well as the South Moravian, Pardubice, Central Bohemian, Pilsen, and Liberec Regions can be defined as metropolitan regions.

    1997-01-01

    A study of urban-related water-qulity effects in the Kansas River, Shunganunga Creek Basin, and Soldier Creek in Topeka, Kansas, was conducted from October 1993 through September 1995. The purpose of this report is to assess the effects of urbanization on instream concentrations of selected physical and chemical constituents within the city of Topeka. A network of seven sampling sites was established in the study area. Samples principally were collected at monthly intervals from the Kansas River and from the Shunganunga Creek Basin, and at quarterly intervals from Soldier Creek. The effects of urbanization werestatistically evaluated from differences in constituent concentrations between sites on the same stream. No significant differences in median concentrations of dissolved solids, nutrients, or metals and trace elements, or median densities offecal bacteria were documented between sampling sites upstream and downstream from the major urbanized length of the Kansas River in Topeka.Discharge from the city's primary wastewater- treatment plant is the largest potential source of contamination to the Kansas River. This discharge increased concentrations of dissolved ammonia, totalphosphorus, and densities of fecal bacteria.Calculated dissolved ammonia as nitrogen concentrations in water from the Kansas River ranged from 0.03 to 1.1 milligrams per liter after receiving treatment-plant discharge. However, most of the calculated concentrations wereconsiderably less than 50 percent of Kansas Department of Health and Environment water- quality criteria, with a median value of 20 percent.Generally, treatment-plant discharge increased calculated total phosphorus concentrations in water from the Kansas River by 0.01 to 0.04 milligrams per liter, with a median percentage increase of 7.6 percent. The calculated median densities of fecal coliform and fecal Streptococci bacteria in water from the Kansas River increased from 120 and 150colonies per 100 milliliters of water

    Full Text Available This research exercise aims to identify all areas affected by what is now known as ‘youthification’ in the Metropolitan Area of Cluj. Broadly speaking, an area touched by youthification witnesses a massive arrival of young adults, who invest in housing, but only remain there until they age. Youthification is usually the second phase within an encompassing process of gentrification. To gain a clearer picture of this phenomenon, we employed a snapshot of the situation recorded by the Population and Housing Census of 2011. Using this image as a starting point, we then applied statistical thresholds aimed at measuring the presence and intensity of youthification within different areas. Thereafter, we looked at areas exhibiting the same level of youthification, in order to find those common traits of their young adult inhabitants that might prove relevant for their choices in matters of housing. Once completed, our efforts resulted in the first map showing the areas affected by youthification within the Metropolitan Area of Cluj. In addition, we reached the following conclusion: Young adults who live in the city are more likely to still be enrolled in a form of education and less likely to be married or to have children than those who live in the suburbs or in rural areas. This observation implies that there might be some hidden dependency relations, which are at work in shaping the choice of housing.

    LaFreniere, L. M.; Environmental Science Division

    2010-01-14

    In 1985, carbon tetrachloride was discovered in the groundwater at Agra, Kansas, during routine sampling of public water supply wells. Two of Agra's four public water supply wells contained low but detectable levels of carbon tetrachloride; the concentrations in wells PWS-3 and PWS-4 exceeded the maximum contaminant level. These wells were removed from service in 1986, although they remain available for uses other than drinking water. Other public wells, outside the area of contamination, supply drinking water for the city of Agra. In 1987-2005, the Kansas Department of Health and Environment (KDHE) and the Commodity Credit Corporation of the U.S. Department of Agriculture (CCC/USDA) conducted investigations to delineate the contaminant plume and to identify source areas for the contamination - which results from the past use of grain fumigants containing carbon tetrachloride. Source areas were identified on the former CCC/USDA grain storage facility property and on the Producers Agricultural Marketing Association, Inc., property located to the south (Argonne 2006). The contaminant plume extends to the southeast, toward well PWS-3, from the identified source areas. Both the CCC/USDA and Pro-Ag Marketing are currently implementing KDHE-approved interim measures (IMs). To address the contamination identified on its former property, the CCC/USDA is implementing a source control IM consisting of large-diameter boreholes (LDBs) coupled with soil vapor extraction (SVE) and air sparging (AS). Pro-Ag Marketing plans to use groundwater extraction to address the downgradient plume. The CCC/USDA and Pro-Ag completed installation of the two interim measures in May 2009 and August 2009, respectively. The performance and assessments of the effectiveness of the IMs are being reported separately by the responsible entities. As part of the IM process, the KDHE (2008) requested the development of a joint sitewide groundwater monitoring plan to allow periodic assessment of the

    2011-01-01

    Although Soviet-era urban-growth controls produced relatively sustainable metropolitan development patterns, low-density suburban sprawl has accelerated markedly in modern Russia. Distinctive features of Moscow's development history are its greenbelt, which dates from 1935 and is becoming increasingly fragmented, proliferation of satellite cities at the urban fringe, conversion of seasonal dachas into full-time residences, the very exclusive Rublevo Uspenskoe Highway development, and today's crippling traffic congestion. The recent economic crisis has slowed development and actually increased the supply of “economy-class” single-family homes, for which there is much pent-up desire but insufficient credit availability to meet the demand. A renewed commitment to sustainability's triple bottom line—environmental quality, equity, and economic prosperity—will require greater government transparency and fairness, stronger planning controls, and an expanded public transportation system.

    2006-01-31

    The Commodity Credit Corporation (CCC), an agency of the U.S. Department of Agriculture (USDA), formerly operated grain storage facilities at two different locations at Everest, Kansas (Figure 1.1). One facility (referred to in this report as the Everest facility) was at the western edge of the city. The second facility (referred to in this report as Everest East) was about 0.5 mi northeast of the town. The CCC/USDA operated these facilities from the early 1950s until the early 1970s, at a time when commercial fumigants containing carbon tetrachloride were in common use by the CCC/USDA and private industry for the preservation of grain in storage. In 1997 the Kansas Department of Health and Environment (KDHE) sampled several domestic drinking water and non-drinking water wells in the Everest area as part of the CCC/USDA Private Well Sampling Program. All of the sampled wells were outside the Everest city limits. Carbon tetrachloride contamination was identified at a single domestic drinking water well (the Nigh well, DW06; Figure 1.1) approximately 3/8 mi northwest of the former Everest CCC/USDA grain storage facility. Subsequent KDHE investigations suggested that the contamination in DW06 could be linked to the former use of grain fumigants at the CCC/USDA facility. For this reason, the CCC/USDA is conducting a phased environmental study to determine the source and extent of the carbon tetrachloride contamination at Everest and to identify potential remedial options. The studies are being performed by the Environmental Research Division of Argonne National Laboratory. Two phases of investigation were completed previously; this report presents the findings of the targeted Phase III investigation at Everest.

    2012-03-31

    On September 30, 2008, the US Department of Energy (DoE), issued a cooperative agreement award, DE-FC26-08NT01914, to the Metropolitan Energy Center (MEC), for a project known as “Kansas Consortium Plug-in Hybrid Medium Duty Certification” project. The cooperative agreement was awarded pursuant to H15915 in reference to H. R. 2764 Congressionally Directed Projects. The original agreement provided funding for The Consortium to implement the established project objectives as follows: (1) to understand the current state of the development of a test protocol for PHEV configurations; (2) to work with industry stakeholders to recommend a medium duty vehicle test protocol; (3) to utilize the Phase 1 Eaton PHEV F550 Chassis or other appropriate PHEV configurations to conduct emissions testing; (4) and to make an industry PHEV certification test protocol recommendation for medium duty trucks. Subsequent amendments to the initial agreement were made, the most significant being a revised Scope of Project Objectives (SOPO) that did not address actual field data since it was not available as originally expected. This project was mated by DOE with a parallel project award given to the South Coast Air Quality Management District (SCAQMD) in California. The SCAQMD project involved designing, building and testing of five medium duty plug-in hybrid electric trucks. SCAQMD had contracted with the Electric Power Research Institute (EPRI) to manage the project. EPRI provided the required match to the federal grant funds to both the SCAQMD project and the Kansas Consortium project. The rational for linking the two projects was that the data derived from the SCAQMD project could be used to validate the protocols developed by the Kansas Consortium team. At the same time, the consortium team would be a useful resource to SCAQMD in designating their test procedures for emissions and operating parameters and determining vehicle mileage.

The sample in this research was 87 metropolitan areas in Europe and was divided into groups, depending on the population and the introduced metropolitan governance model. For each group, a correlation-regression analysis was performed and a weighted average was calculated from the indexes of the economic growth. As the leading index of the economic growth, labor productivity was used, as the final - GDP per capita. Then a comparison was made between the real value of economic growth in each surveyed metropolitan area and

    Low birth weight (LBW) is associated with infant morbidity and mortality. This is the first study of LBW in Kansas using vital statistics to determine maternal and health care system factors associated with LBW. Low birth weight. Determine if prenatal care, maternal socio-demographic or medical factors, or insurance status were associated with LBW. Birth certificate data were merged with Medicaid eligibility data and subjected to logistic regression analysis. Of the 37,081 single vaginal births, LBW rates were 5.5% overall, 10.8% for African Americans, and 5% for White Americans. Lacking private insurance was associated with 34% more LBW infants (AOR 1.34; 95% CI 1.13-1.58), increased comorbidity, and late or less prenatal care. Low birth weight was associated with maternal medical comorbidity and with previous adverse birth outcomes. Insurance status, prenatal care, and maternal health during pregnancy are associated with LBW. Private insurance was consistently associated with more prenatal care and better outcomes. This study has important implications regarding health care reform.

  1. The evolution of groundwater management paradigms in Kansas and possible new steps towards water sustainability

    2012-01-01

    SummaryThe purpose of this paper is to trace the evolution of key water-related laws and management practices in Kansas, from the enactment of the Kansas Water Resources Appropriation Act of 1945 to the present, in order to highlight the state's efforts to create a more sustainable water future and in hopes that others will benefit from Kansas' experience. The 1945 Act provides the basic framework of water law (prior appropriation) in Kansas. Progression of groundwater management in the state encompasses local Groundwater Management Districts (GMDs) and their water-management programs, minimum-streamflow and TMDL standards, water-use reporting and water metering programs, use of modified safe-yield policies in some GMDs, the subbasin water-resources-management program, the integrated resource planning/aquifer storage and recovery project of the city of Wichita, the Central Kansas Water Bank, enhanced aquifer subunits management, and various water conservation programs. While these have all contributed to the slowing down of declines in groundwater levels in the High Plains aquifer and in associated ecosystems, they have not yet succeeded in halting those declines. Based on the assumption that the different management approaches have to operate easily within the prevailing water rights and law framework to succeed, a number of steps are suggested here that may help further diminish or reverse the declines of the High Plains aquifer. These include eliminating the "use it or lose it" maxim in the prior-appropriation framework, broadening the definition of "beneficial use," regulating domestic and other "exempt" wells, encouraging voluntary "sharing the shortage" agreements, and determining to what extent water rights may be regulated in the public interest without a compensable "taking". Further measures include establishing artificial recharge and/or aquifer storage and recovery projects wherever feasible and determining to what extent water-rights holders might be

    Full Text Available The role of Regions appears reconfigured by the "reshaping" of national States. Besides, under a sub-regional scale, forms of governance have been launched, redefining a new territoriality. In Italy, the role of the Regions and Cities is more and more important in the decision-making processes of the territories and it is also characterized by the recent establishment of the metropolitan cities, but still not geo-politically defined. There is, in fact, a constitutional reform process through the region's reorganization legislative autonomy and strengthening of local governments. In this context, some areas are characterized by social unrest that includes new forms of poverty, urban malaise and marginalization, due also to the financial and economic crisis whose signs of recovery are still very weak. In the European Union, the programming decisions considered the policy of development and cohesion also at the local scale. The 2014-2020 EU programming cycle, in fact, has defined the main role of metropolitan cities, but also of cities and internal areas. The contribution will analyze Puglia, region of southern Italy, and the metropolitan area of Bari, the regional capital, in order to verify policies concerning the social field, both through "strategic planning" and launching the so-called "smart city" experience. In the metropolitan city, indeed, there is already an orientation towards the "social innovation" to address the issues of social cohesion and inclusion, consistent to sustainable development.

    Water quality of streams in Johnson County, Kansas was evaluated from October 2002 through December 2007 in a cooperative study between the U.S. Geological Survey and the Johnson County Stormwater Management Program. Water quality at 42 stream sites, representing urban and rural basins, was characterized by evaluating benthic macroinvertebrates, water (discrete and continuous data), and/or streambed sediment. Point and nonpoint sources and transport were described for water-quality constituents including suspended sediment, dissolved solids and major ions, nutrients (nitrogen and phosphorus), indicator bacteria, pesticides, and organic wastewater and pharmaceutical compounds. The information obtained from this study is being used by city and county officials to develop effective management plans for protecting and improving stream quality.

    Full Text Available Cities, main biotope of the Man in the World, glean more and more agricultural lands and natural spaces beyond the distant peripheries. Historic processes such as the mass urbanization or the industrialization based on the exploitation of subsoil resources, have taken over many natural spaces that were destroyed or erased or exploited for economic purposes. The region Nord Pas-de-Calais (France has a rate of arti cialisation of the very high ground, it’s fragmented territory and upset by two world con icts and a intense mining period. So, today, meadows of three quarter of peoples of the region consider that there isn’t enough nature in the heart of their city. Within the framework of the métropolisation, this feeling is accentuated due to urban sprawl, which is more and more important. Since the 1990s, we speak about sustainable development as about a new philosophy that would lead us to a more balanced world between will economic, social, cultural and environmental policies. The region is very invested in the domain, because of the speci cities of its territory. The objective of this investigation was to account for forms that can take the environmental territorial policies and / or whose issues the welfare of citizens through new recreational spaces in nature.

    A dearth of available data on carbon emissions and comparative analysis between metropolitan areas make it difficult to confirm or refute best practices and policies. To help provide benchmarks and expand our understanding of urban centers and climate change, this article offers a preliminary comparison of the carbon footprints of 12 metropolitan areas. It does this by examining emissions related to vehicles, energy used in buildings, industry, agriculture, and waste. The carbon emissions from these sources-discussed here as the metro area's partial carbon footprint-provide a foundation for identifying the pricing, land use, help metropolitan areas throughout the world respond to climate change. The article begins by exploring a sample of the existing literature on urban morphology and climate change and explaining the methodology used to calculate each area's carbon footprint. The article then depicts the specific carbon footprints for Beijing, Jakarta, London, Los Angeles, Manila, Mexico City, New Delhi, New York, Sao Paulo, Seoul, Singapore, and Tokyo and compares these to respective national averages. It concludes by offering suggestions for how city planners and policymakers can reduce the carbon footprint of these and possibly other large urban areas.

    Full Text Available ABSTRACT Social policies, which have gained importance after Industrial Revolution have substantially changed in line with economic understanding. With global oil crisis in the 1970s, the process of transformation in which wealth state enter has also influenced wealth. This process of transformation which can be summarized as passage to free market economy by abandoning Keynesian economic policies, governments come to decentralize their non-fundamental duties to local administrations, private sector or non-governmental organizations. Together with social policy practices of central administrations, local administrations have come to the fore as fundamental social politic actors by moving with the times. The weight of local administrations in social policy systems can vary along countries and in recent years it is seen that municipalities in Turkey has started come to the fore with social policy practices. The concept of social policy is adopted in municipal work as social municipal work. In this context, with social data center project by the Konya Metropolitan Municipality a detailed investigation is carried out on the social fabric of the city. The project aims to inform every relief institution about any relief received in the system, to help those who are indeed need, to prevent repetitive aids and thus abuse, fairly distribute relief supplies, prevent waste of recourses by informing relief institutions to a maximum extend. In this study, the importance of data about social fabric needed to make optimal decisions in conduction of civic services and information obtained was analyzed.

    The atmospheric pollution in the Mexico City Metropolitan Zone (MCMZ), was detected during the 1960's and presents nowadays considerable dimensions. The atmospheric pollution problem evolution in the MCMZ is presented in this paper, considering criteria pollutants as particles and ozone, and hazardous air pollutants as benzene. Successful an unsuccessful experiences looking for improve the air quality in the MCMZ are evaluated. These experiences should be account for in other Mexican cities, as well as in developing countries. The MCMZ air quality evolution is an important case where implemented strategies in order to reduce sulphur dioxide and lead, resulted an increase in levels, frequency and duration of ozone concentrations in the atmosphere. Basic concepts of environmental engineering: prevention, minimization and control, as well as pollution control in the source, must be considered.

    Full Text Available In March 2006, a multiagency field campaign was undertaken in Mexico City called the Megacities Initiative: Local and Global Research Observations (MILAGRO. Two of the five field components of the MILAGRO study focused a major part of their efforts on atmospheric particulate emissions from the Mexico City basin and their effects on radiative balance as a function of time, location and processing conditions. As part of these two MILAGRO components, measurements of aerosol optical properties were obtained at a site located in the northern part of Mexico City (T0 and also at a site located 29 km northwest (T1 to estimate the regional effects of aerosol emissions from the basin.

    Measurements of aerosol absorption and scattering for fine mode aerosols were obtained at both sites. Aerosol absorption at 550 nm was similar at both sites, ranging from 7–107 Mm−1 at T0 and from 3–147 Mm−1 at T1. Aerosol scattering measured at 550 nm at T0 ranged from 16–344 Mm−1 while the aerosol scattering values at T1 were much lower than at T0 ranging from 2–136 Mm−1. Aerosol single scattering albedos (SSAs were calculated at 550 nm for the fine mode aerosols at both sites using these data. The SSAs at T0 ranged from 0.47–0.92 while SSAs at T1 ranged from 0.35–0.86. The presence of these highly absorbing fine aerosols in the lower atmosphere of the Mexico City area will result in a positive climate forcing and a local warming of the boundary layer in the region.

    Broadband UVB intensity was found to be higher at site T0, with an average of 64 μW/cm2 at solar noon, than at site T1, which had an average of 54 μW/cm2 at solar noon. Comparisons of clear-sky modeled UVB intensities with the simultaneous UVB measurements obtained at sites T0 and T1 for cloudless days indicate a larger diffuse radiation field at site T0 than at site T1.

    Full Text Available This unique building, built on a scant 1,560 m2 site, in the downtown area, totals 23,000 m2 of built up area in 20 stories. In a departure from the usual line of office highrises, this building stands out due to the structural solution adopted, a solution which also decisively contributes to the façade design giving a highly individualised architectural character to the building. The most outstanding feature is the way the loads from the 16 upper floors, carried by 24 columns, are transferred to the only 5 piers traversing the lower floors, besides the vertical core. This load transfer is effected in the structure section corresponding to the 4th and 5th storeys and is constituted by 45° triangular shapes forming a trellis which ads an attractive effect to the façade, since this section of the structure is exposed. The all-metal structure, save for the floor construction and the foundations, is also fitted with relatively new fire protection systems and has been specially designed to allow a rather high degree of lateral flexibility in the event of winds in excess of 80 km/hour.

    Esta singular construcción, emplazada en una pequeña parcela de 1.560 m2, en el centro de la ciudad, desarrolla una edificabilidad total de unos 23.000 m2, en sus 20 niveles. Dentro de lo que constituye una respuesta corriente para este tipo de edificios altos destinados a oficinas, en este caso sobresale la solución adoptada para la estructura, solución que, además, contribuye decisivamente en la configuración de las fachadas y confiere una destacada personalidad arquitectónica al edificio. En este sentido, lo más sobresaliente es el método empleado para transferir las cargas de los 16 niveles superiores de la torre, apoyados sobre 24 pilares, a sólo 5 pilares en los niveles inferiores, además del núcleo de enlaces verticales. La estructura de transferencia, que ocupa las plantas 4.ª y 5.ª, se compone de formas triangulares inclinadas 45°, formando retículos que constituyen un atractivo detalle de la fachada, ya que permanecen vistos al exterior. La estructura, enteramente metálica, a excepción del hormigón empleado en los forjados y en las cimentaciones, cuenta además con sistemas de protección contra incendios relativamente nuevos, y ha sido calculado por un sistema especial que permite sensibles desplazamientos laterales en caso de vientos superiores a los 80 km/hora.

    In 1997, low levels of carbon tetrachloride (below the maximum contaminant level [MCL] of 5 {micro}g/L) were detected in groundwater at Inman, Kansas, by the Kansas Department of Health and Environment (KDHE). The 1997 KDHE sampling was conducted under the U.S. Department of Agriculture (USDA) private well sampling program. The Commodity Credit Corporation (CCC), a USDA agency, operated a grain storage facility in Inman from 1954 to 1965. Carbon tetrachloride is the contaminant of primary concern at sites associated with former CCC/USDA grain storage operations. Inman is located in southwest McPherson County, approximately 10 mi southwest of the city of McPherson (Figure 1.1). To determine whether the former CCC/USDA facility at Inman is a potential contaminant source and its possible relationship to the contamination in groundwater, the CCC/USDA has agreed to conduct an investigation at Inman, in accordance with the Intergovernmental Agreement between the KDHE and the Farm Service Agency of the USDA. For this work plan, Argonne compiled historical data related to the previous investigations and grain storage operations at Inman. Through a review of documents acquired from all available sources, other potential contaminant source areas (in addition to the former CCC/USDA facility) have been identified as (1) the commercial grain storage structures northwest of Inman, along the railroad right-of-way, and (2) small former private grain storage facilities west of Main Street and near the former CCC/USDA facility at the southern edge of Inman (Figure 1.2). Previous investigations and the potential source areas are discussed in Section 2.

This project was funded by the Centre for Strategic Urban Research (Realdania Research) and the EU-FP6 integrated research......87 % of the Danish population lives in urban areas and thus urbanisation in Denmark may have come to an end, but urban growth has not. We are continuously using more and more urban land per capita, and the pace is increasing.

    Juracek, Kyle E.; Eng, Ken

    2017-06-26

    An understanding of streamflow alteration in response to various disturbances is necessary for the effective management of stream habitat for a variety of species in Kansas. Streamflow alteration can have negative ecological effects. Using a modeling approach, streamflow alteration was assessed for 129 selected U.S. Geological Survey streamgages in the State for which requisite streamflow and basin-characteristic information was available. The assessment involved a comparison of the observed condition from 1980 to 2015 with the predicted expected (least-disturbed) condition for 29 streamflow metrics. The metrics represent various characteristics of streamflow including average flow (annual, monthly) and low and high flow (frequency, duration, magnitude).Streamflow alteration in Kansas was indicated locally, regionally, and statewide. Given the absence of a pronounced trend in annual precipitation in Kansas, a precipitation-related explanation for streamflow alteration was not supported. Thus, the likely explanation for streamflow alteration was human activity. Locally, a flashier flow regime (typified by shorter lag times and more frequent and higher peak discharges) was indicated for three streamgages with urbanized basins that had higher percentages of impervious surfaces than other basins in the State. The combination of localized reservoir effects and regional groundwater pumping from the High Plains aquifer likely was responsible, in part, for diminished conditions indicated for multiple streamflow metrics in western and central Kansas. Statewide, the implementation of agricultural land-management practices to reduce runoff may have been responsible, in part, for a diminished duration and magnitude of high flows. In central and eastern Kansas, implemented agricultural land-management practices may have been partly responsible for an inflated magnitude of low flows at several sites.

    2015-07-01

    Full Text Available The Metropolitan Area of Oradea has certain directions of development settled in accordance with the objectives of development assumed by The Local Council of Oradea on 10 March 2015 once with the approval of the strategy for development of Oradea Municipality for the period 2016 – 2020. It is very important for for the Municipality of Oradea to become, by quantifiable arguments in a relatively short period of time a real competitor of the great cities surrounding it or of Timişoara, Cluj-Napoca, Arad and Debrecen. Domains, in which Oradea can excel as a clear differentiator in front of its competitor, are closely related to the local traditional specific and resources. Thus, Oradea proposed to be the capital of Art Nouveau and thermal-ism. The fulfilment of this goal would definitely bring more tourists and obviously additional financial resources to the local budget. At this moment, OMA is prepared in what concerns the hotelier infrastructure and utilities for taking the new tourists. In addition, another important objective regarded at macro level for the entire OMA is the assurance of a security comfort for the citizens of the Municipality of Oradea and implicitly of the neighbouring villages. One of the objectives – Oradea, the safest city – is closely linked to another one which represents the follow-up of some successful beginnings in 2012 with the award Oradea – the green city. In the following period an increase of the surfaces covered with green spaces and recreational areas is being planned for the optimum comfort of the inhabitants and tourists of the OMA. The three main objectives mentioned above must be added to the imperative need of completing the necessary investments for the increase of the quality of life. The infrastructure for the assurance of the quality of health and education is reflected by the completed HURO programme accessed by the executive of OMA.

    The aeromagnetic mapping techniques used in a regional aeromagnetic survey of the state are documented and a qualitative regional interpretation of the magnetic basement is presented. Geothermal gradients measured and data from oil well records indicate that geothermal resources in Kansas are of a low-grade nature. However, considerable variation in the gradient is noted statewide within the upper 500 meters of the sedimentary section; this suggests the feasibility of using groundwater for space heating by means of heat pumps.

    Intensive urbanization is swallowing municipal green areas which causes intensification of erosion, decrease in biodiversity and permanent fragmentation of habitats. In the face of these changes, a risk of irreversible damages to urban ecosystems is growing. That is why planning of solutions within the framework of Green Urbanism in metropolitan areas inhabited by over 55% of the global population is of extraordinary importance. The task of the paper is to present patterns of the Green Urbanism using selected examples of metropolitan areas as case studies. The main goal of the research is to make comparison between GU practices in different countries, in various spatial settings. The principles of triple zero framework: zero fossil-fuel energy use, zero waste, zero emissions (from low-to-no-carbon emissions) introduce not only the contemporary trends in theoretical urban planning but are dictated by practical considerations to create a healthy environment for a healthy society with a minimized environmental footprint. The research results help to identify Green Urbanism techniques used for multiple functions, including ecological, recreational, cultural, aesthetic and other uses and present opportunities for implementation of Green Urbanism solutions in metropolitan areas. To achieve healthier society and environment, highly congested and polluted cities have to be recreated through working with the existing landscape, topography and natural resources particular to the site.

    High-resolution near-surface geologic information is essential for seismic hazard reduction in urban areas. Traditionally, a seismic source within the area of study is always desirable for getting the high-resolution information. However, natural earthquake does not usually conveniently occur during periods of seismic observation. Meanwhile, explosive and/or vibrating sources are prohibited to be used in cities. To overcome these limitations for addressing urban seismic hazard reduction, microtremors, the ambient noise of micro-motions in the ground, are becoming valuable sources for extracting the much needed earthquake engineering parameters in urban settings. Using 30 three-component seismometers we have collected microtremor data at more than 1,000 sites in metropolitan Beijing area in the summer of 2007. The data were collected in two ways: 1) along two major roads running roughly orthogonal in NW and NE directions centered in the city center with 200-m seismometer spacing and minimum measurement duration of 1 hour; and 2) seismometer spacing of approximately 1-km that covered the entire area inside Beijing's 5th Beltway. The data are processed with both the horizontal to vertical spectral ratio method (H/V) and space correlation method. The delineated shear wave velocity and the bedrock interface mapping are compared with results by other means. Meanwhile, the newly obtained information on ground motion fundamental frequency and amplification factor will provide further constraints on seismic hazard analysis to those critical structures of the 2008 Summer Olympic Game. This project is supported by the Ministry of Science and Technology of China.

This urban productive process has particular features: the predominance of smallholding, the restricted use of physical space, and the use of recycled materials and organic wastes. The population engaged in agriculture is heterogeneous, and includes women and children. There are a couple of production systems: the suburban, which uses the “chinampa” to produce mainly vegetable and flowers; and the periurban system, which has two sub-systems, the “terraces” producing nopal-vegetable and maize and the “Valleys” producing tuna (fruit and amaranth. The wastes of other systems (straw  and manure are used in these places. The production systems combine pre-hispanic and modern tools, such as the tractor and coa.

    This annual report describes progress during the final year of the project entitled ''Improved Oil Recovery in Mississippian Carbonate Reservoirs in Kansas''. This project funded under the Department of Energy's Class 2 program targets improving the reservoir performance of mature oil fields located in shallow shelf carbonate reservoirs. The focus of the project was development and demonstration of cost-effective reservoir description and management technologies to extend the economic life of mature reservoirs in Kansas and the mid-continent. As part of the project, tools and techniques for reservoir description and management were developed, modified and demonstrated, including PfEFFER spreadsheet log analysis software. The world-wide-web was used to provide rapid and flexible dissemination of the project results through the Internet. A summary of demonstration phase at the Schaben and Ness City North sites demonstrates the effectiveness of the proposed reservoir management strategies and technologies. At the Schaben Field, a total of 22 additional locations were evaluated based on the reservoir characterization and simulation studies and resulted in a significant incremental production increase. At Ness City North Field, a horizontal infill well (Mull Ummel No.4H) was planned and drilled based on the results of reservoir characterization and simulation studies to optimize the location and length. The well produced excellent and predicted oil rates for the first two months. Unexpected presence of vertical shale intervals in the lateral resulted in loss of the hole. While the horizontal well was not economically successful, the technology was demonstrated to have potential to recover significant additional reserves in Kansas and the Midcontinent. Several low-cost approaches were developed to evaluate candidate reservoirs for potential horizontal well applications at the field scale, lease level, and well level, and enable the small

Growth and rankings of MSAs are examined using Pannell's (1974) method. A linear rank-size pattern of cities is revealed, with centers of greatest population growing larger while smaller centers follow with proportionally smaller population changes. A regression model provided some support for the contention that city sizes affect city growth rates. Additional factors in southern metropolitan growth and decline were considered. Introduction of a labor cost factor into the regression model provided moderate support in accounting for variation in MSA growth rates. Several MSAs grew at rates predicted by the regression model while others performed differently than expected. Explanations for variations are presented for selected MSAs." excerpt

  12. [The metropolitan area of Guadalajara. The population growth transition].

    Arroyo Alejandre, J

    1994-01-01

    The Guadalajara metropolitan area, containing approximately three million inhabitants in the municipios of Guadalajara, Zapopan, Tlaquepaque, Tonala, and El Salto, has high rates of population growth due to in-migration, natural increase, and annexation of localities. The average annual rate of growth declined from 6.8% in the 1950s to 2.6% in the 1980s. Despite the decline, which can be considered an indicator of transition, the increase in absolute numbers resulting from a 2.6% rate of growth amounts to 78,000 new inhabitants each year. A change has occurred in recent decades in the migratory patterns and urban spatial distribution of Western Mexico. In-migration to the Guadalajara metropolitan zone has slowed in both absolute and relative terms. Growth of smaller and intermediate sized cities is now more rapid than is that of the metropolitan zone. Surveys in Guadalajara indicate that the proportion of in-migrants from urban areas has increased substantially. Despite the slowing pace of growth, the Guadalajara metropolitan area faces serious problems of housing, land use, transport, and urban infrastructure and services in general. Because of rapid growth and the preponderance of young people among the migrants, the problems are likely to persist for some time. Population projections suggest that 66,000 new jobs will be needed during 1990-95 and 57,000 during 1995-2000, assuming no significant increases in the proportion of women who work. An average of 2500 hectares of land will be needed every five years, nearly equivalent to the total area of the city in 1940. The number of daily trips on urban transit is projected to increase from 6 million at present to 7 million in 2005. The daily load of solid waste is expected to increase from 4000 to 5000 tons in 2005. The economic structure of the city is also changing. Commerce and small and medium-sized manufacturing enterprises have lost their primacy and large national and transnational manufacturing and commercial

  14. Multiplex networks in metropolitan areas: generic features and local effects

    2015-01-01

    Most large cities are spanned by more than one transportation system. These different modes of transport have usually been studied separately: it is however important to understand the impact on urban systems of the coupling between them and we report in this paper an empirical analysis of the coupling between the street network and the subway for the two large metropolitan areas of London and New York. We observe a similar behaviour for network quantities related to quickest paths suggesting the existence of generic mechanisms operating beyond the local peculiarities of the specific cities studied. An analysis of the betweenness centrality distribution shows that the introduction of underground networks operate as a decentralising force creating congestions in places located at the end of underground lines. Also, we find that increasing the speed of subways is not always beneficial and may lead to unwanted uneven spatial distributions of accessibility. In fact, for London -- but not for New York -- there is ...

  15. Status of Groundwater Levels and Storage Volume in the Equus Beds Aquifer Near Wichita, Kansas, January 2009

    Hansen, Cristi V.

    2009-01-01

    Beginning in the 1940s, the Wichita well field was developed in the Equus Beds aquifer in southwestern Harvey County and northwestern Sedgwick County to supply water to the city of Wichita (Williams and Lohman, 1949). In addition to supplying drinking water to the largest city in Kansas, the other primary use of water from the Equus Beds aquifer is to irrigate crops in this agriculture-dominated part of south-central Kansas (Rich Eubank, Kansas Department of Agriculture, Division of Water Resources, oral commun., 2008). The decline of water levels in the aquifer were noted soon after the development of the Wichita well field began (Williams and Lohman, 1949). As water levels in the aquifer decline, the volume of water stored in the aquifer decreases and less water is available to supply future needs. For many years the U.S. Geological Survey (USGS), in cooperation with the city of Wichita, has monitored these changes in water levels and the resulting changes in storage volume in the Equus Beds aquifer as part of Wichita's effort to effectively manage this resource. In 2007, the city of Wichita began using Phase I of the Equus Beds Aquifer Storage and Recovery (ASR) project for large-scale artificial recharge of the Equus Beds aquifer. The ASR project uses water from the Little Arkansas River - either pumped from the river directly or from wells in the riverbank that obtain their water from the river by induced infiltration - as the source of artificial recharge to the Equus Beds aquifer (City of Wichita, 2009).

    Full Text Available Growth dynamics in contemporary cities and their territorial organization are subject to the influence of economic activities associated with creative industries. In this research, we perform a spatial analysis of such creative industries across all metropolitan areas of Mexico during the period. In order to show the spatial relevance that creative industries have over the urban structure, we calculate the employment concentration of each of the sectors and subsectors with respect to the distance from the closest metropolitan area’s Central Business District. We conclude that creative industries tend to localize close to the Metropolitan Areas’ CBD and they are the ones with greater capacity to generate positive externalities on employment growth.

    This paper hopes to fill this gap by working with the notion of environmental justice and by introducing hydrographical systems as an important level of analysis, together with the municipal and metropolitan scales. In that sense, the environment figures as the basis to correlate social, economical....... The ocean front is historically the wealthiest region of the metropolitan area and is visually and physically separated from the Rio de Janeiro suburbs by mountains characterising a schism between two cities: the ocean front extensively provided with environmental amenities and the suburbs marked...... by environmental degradation. This condition is true, but the metropolitan dynamic goes beyond that schism and this analysis reveals the dichotomy and contradictions of the hydrographical systems where wealthy and low income neighbourhoods divide the same ecological system and deal with their environmental...

    When psychiatric hospitalization is over-used, it represents a financial drain and failure of care. We evaluated implementation and cessation of transporting people medically certified for psychiatric hospitalization to a central psychiatric emergency service for management and re-evaluation of hospitalization need. After implementation, the hospitalization rate declined 89% for 346 transported patients; only four of the nonhospitalized patients presented in crisis again in the next 30 days. Following cessation, the hospitalization rate jumped 59% compared to the preceding year. Costs declined 78.7% per diverted patient. The findings indicate that it is possible to reduce hospitalization and costs, and maintain quality care.

    Zhukovsky, Roman; Pomorov, Sergey

    2017-01-01

    The paper is aimed at investigating and compiling systematic knowledge about the factors affecting formation and specificity of urban sub-downtowns (sub-centers). Sub-downtowns are autonomous territories, identical to the downtown and located within one metropolitan area with downtown. Objects corresponding to the concepts of "Edge City", "Edgeless City", "Secondary Business District", "Mixed-Use Development" were investigated as sub-downtowns. Terrestrial and satellite images, as well as functional zoning data of more than 250 metropolitan areas in all world's regions were explored. A special form of sub-downtowns characterized by direct commercial corridor connection with central business district was found and defined as "Total Business District" concept. Eight metropolitan area types were distinguished based on sub-downtown development level criterion. These types were found to have significant relation to the specific world regions. Sub-downtowns are more frequent and diverse in countries with higher level, pace and liberalization of economic development, as well as with higher motorization rate. The closer to the coast or state border the metropolitan area is, the more likely sub-downtowns within it will be developed. In the context of continental, desert, tropical, northern maritime climates sub-downtowns are less common than in subtropical, temperate and Mediterranean or Polynesian climates. In most cases, clustered (not just corridor-like) sub-downtowns are likely to be found in metropolitan areas with a population of more than 1.5-3.5 million people, depending on the geographic region of the world. The research results can improve forecasting the development and master planning of sub-downtowns in specific metropolitan areas.

  2. Groundwater-level and storage-volume changes in the Equus Beds aquifer near Wichita, Kansas, predevelopment through January 2015

    2015-10-01

    Development of the Wichita well field began in the 1940s in the Equus Beds aquifer to provide the city of Wichita, Kansas, a new water-supply source. After development of the Wichita well field began, groundwater levels began to decline. Extensive development of irrigation wells that began in the 1970s also contributed to substantial groundwater-level declines. Groundwater-level declines likely enhance movement of brine from past oil and gas production near Burrton, Kansas, and natural saline water from the Arkansas River into the Wichita well field. Groundwater levels reached a historical minimum in 1993 because of drought conditions, irrigation, and the city of Wichita’s withdrawals from the aquifer. In 1993, the city of Wichita adopted the Integrated Local Water Supply Program to ensure that Wichita’s water needs would be met through the year 2050 and beyond as part of its efforts to manage the part of the Equus Beds aquifer Wichita uses. A key component of the Integrated Local Water Supply Program was the Equus Beds Aquifer Storage and Recovery project. The Aquifer Storage and Recovery project’s goal is to store and eventually recover groundwater and help protect the Equus Beds aquifer from oil-field brine water near Burrton, Kansas, and saline water from the Arkansas River. Since 1940, the U.S. Geological Survey has monitored groundwater levels and storage-volume changes in the Equus Beds aquifer to provide data to the city of Wichita in order to better manage its water supply.

  3. From the metropolitan area to the urban sprawl: the patchiness of the territory

    Directory of Open Access Journals (Sweden)

    Giuseppe Mazzeo

    2010-02-01

    Full Text Available  The paper tackles the phenomenon of the urban expansion through two concepts: metropolitan area and sprawl. The first, heir of the rational and positivist tradition of development, would lead to orderly and efficient metropolis; the second, son of the capitalist individualism and of the environmentalist emergency, considers the expanded city as one of the symbols of the process of unlimited appropriation of the space. Between these two concepts there is the short period of last crisis of the city, the two decades from 1970s to 1980s. From this moment the city is emerged acting out towards three main directions: the first is the expulsion of activities considered unessential; the second is the repossession of abandoned parts of the city and their transformation into high quality urban districts; the third is the search for new meanings and new perspectives, with the following marketing actions that appear to be central in the city’s policies. In this process it is interesting to observe that the actions regarded as positive are physically positioned in different places from the negative ones: when one talk about urban rehabilitation the mind runs to downtown or to semi-central urban areas; the same when one talk about actions on the image of the city. The final section of the paper examines the metropolitan area of Naples. The analysis is conducted by a qualitative point of view (in relation to the functional character of the metropolitan area and by a quantitative point of view (in relation to the changes of the population structure over the past 150 years. In this regard, the “analytical metropolitan area” has nothing to do with the potential administrative boundaries.

    Full Text Available Data from the annual, seasonal, and hourly behavior of the criteria air pollutants CO, NO2, SO2, O3, and PM10 in three Mexican metropolitan areas (the Mexico City Metropolitan Area (MCMA, Guadalajara Metropolitan Area (GMA, and Monterrey Metropolitan Area (MMA over the period 2000–2011 were analyzed; and compliance with Mexican air quality standards was evaluated, highlighting causes of specific episodes of high and low concentrations. Data analyzed were collected from automatic air-monitoring networks located in the MCMA (32 stations, GMA (8 stations, and MMA (5 stations. In the MCMA and MMA, correlations between wind direction and concentrations of SO2 suggest that there was a considerable contribution of trans-boundary transport from outside of these areas. Analysis of annual trends revealed large reductions of CO in the MCMA, and SO2 in the three metropolitan areas. However, the annual mean concentration of O3 increased by 47% and 42% in the GMA and MMA, respectively, from 2000 to 2011, but decreased by 13% in the MCMA from 2005 to 2010. The annual mean concentration of PM10 in the MMA was about 58% and 76% higher than that in the MCMA and GMA, respectively, from 2001 to 2010.

    In this study, migration data compiled by the Internal Revenue Serve (IRS) and the US Census Bureau for 2006-07 were used to analyse internal migration patterns using migration and income effectiveness for the counties containing the 25 most populous cities in the United States. The results indicated that both large metropolitan and rural counties have lost population and income due to migration. Small metropolitan and non-metropolitan counties closer to cities gained population and income. Counties in South Florida attracted a large number of higher-income migrants from the largest cities in the US. In the last 13 years, New York, Los Angeles and Chicago, the three most populous cities in the US, had negative migration effectiveness. Suburban areas and second-tier cities continued to attract people from large metropolitan areas.

    Morandini, James S; Blaszczynski, Alexander; Dar-Nimrod, Ilan; Ross, Michael W

    2015-06-01

    To determine whether lesbian, gay and bisexual (LGB) Australians residing in rural-remote and other non-inner metropolitan localities experience increased levels of minority stress and reduced social support relative to their inner metropolitan counterparts. A convenience sample of (n=1306) LGB Australians completed an online survey that assessed minority stressors, level of connection with other LGB individuals and social isolation. Postcodes provided were coded into three metropolitan and two rural zones. A series of hierarchical regression analyses were undertaken to examine the effect of locality on minority stress and social support independent of sex, age, ethnicity, education and income. Those residing in rural-remote localities reported significantly increased concealment of sexuality from friends, more concern regarding disclosure of sexuality, less LGB community involvement, fewer friendships with other LGB people and, among men, higher levels of internalised homophobia than those residing in inner metropolitan areas. Unexpectedly, those residing in outer metropolitan areas of major cities experienced comparable levels of minority stress and LGB disconnection to those in rural and remote Australia. LGB individuals in rural-remote and outer metropolitan areas of major cities face increased exposure to a number of minority stressors and less LGB community connectedness. These are risk factors associated with psychiatric morbidity in LGB populations. Health promotion targeted at reducing homophobia and discrimination in rural-remote and outer metropolitan communities and additional services to assist LGB Australians struggling with stigma and isolation in non-inner city areas may help mitigate the disadvantages faced by these LGB populations. © 2015 Public Health Association of Australia.

    2010-12-01

    Cities are particularly vulnerable to heat waves, firstly because they concentrate the majority of the population and, secondly because the heat island that characterizes the urban climate exacerbates heat wave effects. This work is part of the interdisciplinary VURCA project (Vulnerability of cities to heat waves), which deals with the evolution of heat wave events in the context of global warming, urban vulnerability and adaptation strategies. The aim of this study is to analyse urban heat wave events in present climate (1950-2009) and their evolution in an enhanced greenhouse gazes future climate (2010-2100). We used daily observations of temperature from several stations covering Paris metropolitan area and climate projections following three different IPCC-SRES scenarios (B1, A1B, A2) and issued from several ENSEMBLES regional climate models. The heat wave definition is based on the indexes of the operational French warning system. A heat wave is detected within observed or simulated time-series by a heat wave peak, when the temperatures exceed the value of the 99.9th percentile. Its duration is determined by all adjacent days to this peak, for which the temperatures are not durably smaller than the 99.9th percentile value minus 2 °C. The 99.9th percentile threshold is inferred from quantile-quantile plots produced for each climate model in comparison with observations for the reference period 1950-2000. Heat waves have been extracted within observations and 12 climatic simulations. The number of heat wave events and cumulated HW days per year have been calculated, the maximum being seven heat waves cumulating more than 60 HW days in one year in the case of the A2 scenario and until 50 days in the case of the more moderate A1B scenario. From 2050, the occurrence of three or four HW events per year is becoming the norm all scenarios taken together. The evolution of heat wave features has been analysed, highlighting the large variability of the climatic

    Full Text Available Au début du xxie siècle, les espaces urbains traversent une période de croissance et de transformation radicale. Les villes s’étendent de plus en plus. Leur configuration spatiale devient de plus en plus décentralisée et fragmentée. La dichotomie traditionnelle entre hiérarchie urbaine et périphérie est en train de disparaître. Les nouveaux espaces métropolitains sont caractérisés par des processus de segmentation et de spécialisation à distance ainsi que par des polarisations sociales qui structurent l’espace. Les tentatives de planification des villes-régions essaient de rééquilibrer ces processus qui font éclater la ville. Cet article explore brièvement les transformations métropolitaines actuelles en utilisant une approche générique. Il se focalise également sur les stratégies des métropoles pour affronter ces défis dans le cadre de situations institutionnelles variées, un peu partout en Europe. En troisième lieu, cet article interroge les effets potentiels des projets urbains sur un rééquilibrage des transformations urbaines. Comment les grands projets urbains sont-ils conceptuellement élaborés ? Comment les alliances d’acteurs qui les soutiennent se forgent-elles ? Comment les citoyens et les groupes sociaux sont-ils impliqués de manière à produire de nouveaux espaces plus intégrés ?At the beginning of the 21st century, urban spaces can be said to be in a stage of growth and radical transformation.

    Yamashita, Shuji

    In this study, the detailed horizontal structure, i.e. cliffs and plateaux of the heat island of the Metropolitan Tokyo area is investigated. According to Oke (1977), cliff is steep temperature gradient at the rural/urban boundary and plateau is a steady but weaker horizontal gradient of increasing temperature towards the city center. However, these features are not always evident, e.g. large city like Tokyo. To elucidate such aspects, moving observations of the horizontal distribution of air temperature from electric trains of the transportation network of Metropolitan Tokyo during late evening or early morning were thus conducted. In total, 16 railroad lines were used for the moving observations. The observations were done in two phases for sectional and horizontal distributions. Results show that three cliffs exist in the heat island of Metropolitan Tokyo, although the location of these cliffs should be taken into consideration for urban planning or urban redevelopment.

    We study how urban quality evolves as a result of carbon dioxide emissions as urban agglomerations grow. We employ a bottom-up approach combining two unprecedented microscopic data on population and carbon dioxide emissions in the continental US. We first aggregate settlements that are close to each other into cities using the City Clustering Algorithm (CCA) defining cities beyond the administrative boundaries. Then, we use data on CO2 emissions at a fine geographic scale to determine the total emissions of each city. We find a superlinear scaling behavior, expressed by a power-law, between CO2 emissions and city population with average allometric exponent β = 1.46 across all cities in the US. This result suggests that the high productivity of large cities is done at the expense of a proportionally larger amount of emissions compared to small cities. Furthermore, our results are substantially different from those obtained by the standard administrative definition of cities, i.e. Metropolitan Statistical Area (MSA). Specifically, MSAs display isometric scaling emissions and we argue that this discrepancy is due to the overestimation of MSA areas. The results suggest that allometric studies based on administrative boundaries to define cities may suffer from endogeneity bias.

    2012-01-01

    Full Text Available At its population peak in the 1950’s, Detroit, Michigan was inhabited by almost two million residents and served as the car capital of the country. Today, however, the population has dropped by more than fifty percent. With the loss of Detroit residents to surrounding cities and counties, the wedge between Detroit and the suburbs has grown wider. Detroit, once considered the crown jewel of the state of Michigan, is now treated as an immovable stain by its surrounding municipalities. What this means for the metro Detroit area is a high level of governmental fragmentation, preventing economic opportunities for both the city and its suburbs. This is especially unfortunate for the economy of the metro Detroit area because of the current economic crisis in the state of Michigan. With the state’s long tradition of home rule and pride in autonomous, municipal decision-making, municipalities in the metro Detroit area might better realize economic opportunities and the relief they can bring to their own local economies by not only collaborating with the city of Detroit, but with neighboring cities as well.

    2017-07-01

    Sudden infant death syndrome (SIDS) is the leading cause of death among infants aged 1 to 12 months. The purpose of this study was to assess prenatal and postnatal physicians' knowledge about SIDS in a county with high rates of SIDS deaths. A cross-sectional survey was conducted of pediatricians, family practitioners, and obstetricians in Sedgwick County, Kansas. Most physicians reported correctly that there were effective measures to reduce SIDS. Most respondents agreed it was important to discuss SIDS with parents. Pediatricians were more likely than family practitioners and obstetricians to recognize that pacifier use is important for infants in their first year to reduce SIDS and 2 to 4 months is the age range for peak incidence of SIDS. Pediatricians, family practitioners, and obstetricians are knowledgeable about SIDS and SIDS risk reduction. However, they are not allocating adequate time for discussing SIDS and SIDS reduction efforts with patients.

    To determine the prevalence of active epilepsy in two southeastern rural Kansas counties. Medical records were abstracted from the emergency rooms, out- and inpatient services and clinics of 9 hospitals, from 10 doctors' offices, and 1 nursing home in and surrounding the two counties. Letters were mailed from hospitals and doctors' offices to invite their potentially eligible patients to participate in an interview. Medical record information and the interview, when available, were used for the final determination of active epilepsy, seizure type, etiology, syndrome, age, and gender in consensus conferences. Prevalence of epilepsy was calculated, and capture-recapture methodology, which estimates prevalence based on what is known about the population, was employed to assess active epilepsy in the two counties. This study identified 404 individuals with active prevalent epilepsy who visited at least one of the 20 facilities during the observation period. The overall prevalence of active epilepsy was 7.2 per 1000. The seizure type for 71.3% of prevalent cases was unknown; among the 76 cases with known and classifiable seizure type, 55.3% had focal with secondary generalized seizures. Among the 222 cases with classifiable etiology, 53.1% were idiopathic/cryptogenic. About 75% (n=301) were captured at only one center, 72% (n=75) of the remaining 103 patients were captured at two centers, and 28 patients were identified at three or more centers. The capture-recapture assessment yielded an estimation of 982 prevalent patients. The overall estimated prevalence of epilepsy in the two Kansas counties using capture-recapture was 17 per 1000. The crude prevalence of epilepsy, using medical record survey methods, was similar to, but on the high end, of other total population prevalence studies in the United States. The capture-recapture assessment suggested that epilepsy prevalence might be considerably higher than the crude prevalence. Copyright © 2014 Elsevier B.V. All

    OBJECTIVE To analyze the correlation between sociodemographic factors and working conditions of bus workers in a metropolitan area and violence against them. METHODS This cross-sectional study used a nonprobabilistic sample estimated according to the number of workers employed in bus companies located in three cities in the Belo Horizonte metropolitan region in 2012 (N = 17,470). Face-to-face interviews were conducted using a digital questionnaire. The factors associated with violence were analyzed in two stages using Poisson regression, according to each level. The magnitude of the association was evaluated using prevalence ratios with robust variance and a statistical significance of 5%, and 95% confidence intervals were obtained. RESULTS The study sample comprised 782 drivers and 691 fare collectors; 45.0% participants reported at least one act of violence in the workplace in the last 12 months, with passengers being predominantly responsible. The age of the bus workers was inversely associated with violence. Chronic diseases, sickness absenteeism, and working conditions were also associated with violence. CONCLUSIONS The findings on the correlation between violence and working conditions are essential for implementing prevention strategies by transportation service managers. PMID:25741657

    Full Text Available Abstract Background Metabolic syndrome (MS is a combination of medical disorders that increase one's risk for cardiovascular disease and diabetes. Little information exists on the prevalence of MS in a general adult population in Taiwan. Methods We did a cross-sectional survey in a representative sample of 2,359 Chinese adults aged 40 years and over who lived in a metropolitan city, Taiwan in 2004–05. MS was defined by Adult Treatment Panel III criteria modified for Asians. Results The prevalence of MetS was 35.32% and 43.23% in men aged 40–64 years and 65 years and over, respectively, and 24.19% and 51.82% in women aged 40–64 years and 65 years and over. Older age, postmenopausal status, higher body mass index, current smoking, low education attainment, low household income, no alcohol consumption, lower level of occupation physical activity, and a family history of diabetes were associated with increased odds of MetS. Conclusion MetS was present in more than 30% of the Taiwan adult population aged 40 years and over in a metropolitan area; there were substantial variations by age and body mass index groups.

    2010-01-01

    A part of the Equus Beds aquifer in southwestern Harvey County and northwestern Sedgwick County was developed to supply water to residents of Wichita and for irrigation in south-central Kansas. Groundwater pumping for city and agricultural use caused water levels to decline in a large part of the aquifer northwest of Wichita. In 1965, the city of Wichita began using water from Cheney Reservoir in addition to water from the Equus Beds aquifer to meet the city's increasing demand for water. Irrigation pumpage in the area increased substantially during the 1970s and 1980s and contributed to the water-level declines. Water-level declines reached their maximum to date in October 1992.

    2012-03-01

    Studies in Philadelphia, New York City, Houston, Washington, DC, and Greenville, North Carolina, have revealed high lead levels in drinking water. Unlike urban areas, lead levels in drinking water in suburban and rural areas have not been adequately studied. In the study described in this article, drinking water in primary schools and preschools in five suburban and rural south central Kansas towns was sampled to determine if any exceeded the U.S. Environmental Protection Agency (U.S. EPA) guidance level for schools and child care facilities of 20 parts per billion (ppb). The results showed a total of 32.1% of the samples had detectable lead levels and 3.6% exceeded the U.S. EPA guidance level for schools and child care providers of 20 ppb. These results indicate that about one-third of the drinking water consumed by children age six and under in the five suburban and rural south central Kansas towns studied has some lead contamination, exposing these children to both short-term and long-term health risks. The authors suggest a need for increased surveillance of children's drinking water in these facilities.

  7. Hardground petrography and carbonate microfacies: Paola Limestone (Upper Pennsylvanian), southeastern Kansas

    Energy Technology Data Exchange (ETDEWEB)

    Dawson, W.C.; Carozzi, A.V.

    1983-03-01

    The Paola Limestone (Missourian) of the Mid-Continent region is the basal carbonate member of the Iola Formation (Kansas City Group). The Paola is a thin (1 to 3 ft; .3 to .9 m) massive layer of bioturbated, fossiliferous (algae, crinoids, and foraminifers) calcilutite containing abundant phosphate nodules. In a NE-SW outcrop trend across Allen County, Kansas, the Paola Limestone forms the initial substrate on which a phylloid algal buildup developed within the Raytown Limestone. The Paola consists of three distinctive carbonate microfacies (described below). Microfacies 2 overlies microfacies 1; this microfacies association occurs only beneath the phylloid algal buildup. Both exhibit petrographic features indicative of submarine lithification. Northeastward, away from the phylloid algal buildup, microfacies 1 and 2 change abruptly into microfacies 3. Prior to lithification, the hardground (microfacies 1) was bioturbated; following lithification it was scoured, encrusted, and bored. The lithification of microfacies 1 is inferred to have occurred in a submarine environment because: (1) it contains a fauna of encrusting marine organisms and (2) petrographic features indicative of subaerial exposure are lacking. Microfacies 2 is interpreted as a firm ground. Microfacies 3 represents a normal, shallow marine subtidal environment. Because petroleum accumulations are commonly associated with diastems, an awareness of these features could provide insights for the location of some obscure hydrocarbon traps. Additionally, hardgrounds can create intraformational permeability barriers; the recognition of such reservoir heterogeneities is essential for optimum hydrocarbon recovery.

    active migrants to the metropolitan areas was the production workers, comprising mostly laborers, building construction workers, and factory operators. 2 other important groups were sales workers and service workers. Rather than concentrating total emphasis on large urban centers, authorities should divert a portion of their developmental efforts to small towns as part of overall comprehensive urban planning. Economic revitalization of the small towns can take many forms, such as encouraging craft industries, investing labor intensive industries, or offering incentives to industries. Small towns should be given a unifying role within the city rural framework.

    Full Text Available This paper analyses the problems derived from the metropolitan cities entities in Italy and the simultaneous reform of the provinces. These two issues are part of a broader and current Italian political debate related to targets for reduction of public spending and have to do with the achievement of a new order of local government different from that established in the Title V of the Italian Constitution after its 2001 reform. After an examination of previous attempts to regulate metropolitan cities entities, the article examines the aspects contained in decree law on spending review (d.l. n. 95/2012. In this way, the article aims to highlight both the difficulties and incoherencies of the identification of administrative functions and of the general structure to be assigned to the new level of government (the metropolitan city, provided in the Italian Constitution in 2001 but not yet established. Consequently, the article considers the effects that this new model has upon the other and already existing levels of government (such as municipalities, as provinces and as regions.

    A hierarchical metropolitan quantum cryptography network upon the inner-city commercial telecom fiber cables is reported in this paper. The seven-user network contains a four-node backbone net with one node acting as the subnet gateway, a two-user subnet and a single-fiber access link, which is realized by the Faraday-Michelson Interferometer set-ups. The techniques of the quantum router, optical switch and trusted relay are assembled here to guarantee the feasibility and expandability of the quantum cryptography network. Five nodes of the network are located in the government departments and the secure keys generated by the quantum key distribution network are utilized to encrypt the instant video, sound, text messages and confidential files transmitting between these bureaus. The whole implementation including the hierarchical quantum cryptographic communication network links and corresponding application software shows a big step toward the practical user-oriented network with high security level.

    Full Text Available A strong collision between the Eurasian and Philippine Sea Plates causes high seismicity in the Taiwan region. A substantial number of cities and large towns exist on thick sediments in western Taiwan. Larger-magnitude inland earthquakes, for example the 1999 Chi-Chi earthquake, can cause serious damage in urban areas. Consequently, urban seismology is of great interest to the local seismological community. The Taipei Metropolitan Area (TMA is the political, economic, and cultural center of Taiwan. It is situated over a region where the Philippine Sea plate subducts the Eurasian plate. Although seismicity in the TMA is lower than other areas of Taiwan, earthquakes still occur. Seismic risk mitigation is of grave concern in the TMA because of its high population, number of tall buildings, mass rapid transit system, and two nearby nuclear power plants. In this article, procedures for seismic risk mitigation, previous studies, core issues for future research and related topics are described and reviewed.

    Full Text Available Few phenomena are more ubiquitous than traffic, and few are more significant economically, socially, or environmentally. Any virtual reality system, including virtual globes and immersive multi-player worlds that are set in a modern or futuristic setting feature traffic systems. Virtual reality models can also aid in addressing the challenges of real-world traffic systems, the ever-present gridlock and congestion in cities worldwide: traffic engineers and planners can diagnose system instabilities and explore control strategies in virtual worlds reconstructed from available sensor data. To create these systems, road network models need to be created and represented. Traffic needs to be realistically and efficiently simulated. To analyze real-world scenarios, the traffic conditions need to be estimated and reconstructed. To create virtual scenarios, such as simulated cities, traffic needs to be intelligently and efficiently routed.

    The results obtained through the application of an air quality model: AQUAMI for the Metropolitan Area of Mexico City, are presented. The model requires of a photochemical mechanism and the information regarding the total amount of nitrogen oxides and hydrocarbons emitted to the air during that time. In this way the maximum concentrations of ozone that can be reached for the possible ratios of hydrocarbons and nitrogen oxides are obtained. The results are plotted and with them it can be determined that if the nitrogen oxide emission can be diminished, this will impact directly on the ozone emission. Furthermore, the evolution of another product derived of the presence of nitrogen oxides, the peroxiacil nitrate, which is irritant to the respiratory mucosa and to the eyes, is also presented. Through this simulation model the impact derived of the actions aimed at reducing the formation of nitrogen oxides and the release of hydrocarbons at the level of the formed ozone by the sunlight effect. With this basis the ecological impact of the actions such as the following, can be discussed: -improve the combustion process in all thermal equipment. -improve the quality of the fossil fuels utilized. -slightly modify the operational habits in the industrial sector trying that the intensive use of fuels be displaced towards the evening and night hours, when the sunlight incidence is less or null.

    To examine geographical imbalances by analyzing new graduate nurses' migration patterns among regions where they grew up, attended nursing school, and had their first employment and to identify factors related to working in non-metropolitan areas. The sample consisted of 507 new graduates working in hospitals as full-time registered nurses in South Korea. Migration patterns were categorized into 5 patterns based on sequential transitions of "geographic origin-nursing school-hospital." Multiple logistic regression analysis was conducted to identify factors associated with working in non-metropolitan hospitals. Nurses who grew up, graduated, and worked in the same region accounted for the greatest proportion (54%). Sixty-five percent had their first employment in the region where they graduated. Nurses tended to move from poor to rich regions and from non-metropolitan to metropolitan areas. Working in non-metropolitan hospitals was related to older age, the father having completed less than 4 years of college education, non-metropolitan origin, non-capital city school graduation, and a diploma (vs. baccalaureate) degree. Admitting students with rural backgrounds, increasing rural nursing school admission capacities, and providing service-requiring scholarships, particularly for students from low-income families, are recommended to address geographical imbalances.

    The downward trend in the sex ratio at birth that has occurred in several countries over the last 30 years was postulated to signal a deterioration in environmental conditions, particularly unfavourable for male conception and fetus survival. In Italy, in contrast, an upward trend has been observed. Assuming that exposure to reproductive hazards occurs mainly in the major cities, we contrasted the 1970-1995 sex ratio trend for the metropolitan area (defined as the four provinces containing the largest Italian cities) with that for the non-metropolitan area (defined as the rest of the country). In the metropolitan area, the proportion of live-born males showed a negative trend significantly different from the positive trend observed in the rest of the country. Moreover, the stillbirth rate among males was constantly and significantly higher in the metropolitan area. Our results suggest that the decrease in the sex ratio at birth observed in the metropolitan area might be interpreted as a signal of increasing exposure to hazardous environmental conditions for male conceptions and neonates.

    The Commodity Credit Corporation of the U.S. Department of Agriculture (CCC/USDA) operated a grain storage facility at Barnes, Kansas, during most of the interval 1949-1974. Carbon tetrachloride contamination was initially detected in 1986 in the town's public water supply wells. In 2006-2007, the CCC/USDA conducted a comprehensive targeted investigation at and near its former property in Barnes to characterize this contamination. Those results were reported previously (Argonne 2008a). In November 2007, the CCC/USDA began quarterly groundwater monitoring at Barnes. The monitoring is being conducted on behalf of the CCC/USDA by Argonne National Laboratory, in accord with the recommendations made in the report for the 2006-2007 targeted investigation (Argonne 2008a). The objective is to monitor the carbon tetrachloride contamination identified in the groundwater at Barnes. The sampling is presently conducted in a network of 28 individual monitoring wells (at 19 distinct locations), 2 public water supply wells, and 1 private well (Figure 1.1). The results of the 2006-2007 targeted investigation and the subsequent monitoring events in November 2007 (Argonne 2008b), March 2008 (Argonne 2008c), and July 2008 (Argonne 2008d) demonstrated the presence of carbon tetrachloride contamination in groundwater at levels exceeding the Kansas Department of Health and Environment (KDHE) Tier 2 risk-based screening level (RBSL) of 5.0 {micro}g/L for this compound. The contaminant plume appears to extend from the former CCC/USDA property northwestward, toward the Barnes public water supply wells. Information obtained during the 2006-2007 investigations indicates that at least one other potential source might have contributed to the groundwater contaminant plume (Argonne 2008a). The former agriculture building owned by the local school district, located immediately east of well PWS3, is also a potential source of the contamination. This current report presents the results of the

    Full Text Available Public water supply management is a complex process that requires the implementation of a series of accountability, coordination and regulatory mechanisms in order to guarantee continual supply of this vital liquid to the maximum number of people, maximizing spatial and hourly coverage. This article examines the case of a Mexican city that has been expanding until reaching the size of a metropolitan zone, i.e. Aguascalientes, analyzing in a critical manner the argument that intermunicipal governance of public services emerges as a response to increasingly complex needs of metropolitan regions, which need to offer quality services to a growing and demanding population.

  8. Metropolitan reform in Allegheny County: the local failure of National Urban Reform Advocacy, 1920-1929.

    Glass, Michael R

    2011-01-01

    During the 1920-1929 period, the Civic Club of Allegheny County supported political consolidation of the county's municipalities and townships. Civic Club leaders sought boundary reform to tackle perceived social problems and political inefficiencies in the Pittsburgh region. This policy was aligned with a national network of Progressive urban reformers, some of whom guided the Civic Club's plans. These reform efforts culminated in the 1929 Metropolitan Charter, which was rejected by Allegheny County voters. Traditional explanations of this failed vote emphasize the high threshold for success of the charter. However, such accounts ignore the apparent disjunction between the national perception of regional problems and the local reception of recommended solutions. Reform advocates were unable to adapt national Progressive theories to the local context of Allegheny County. This article first describes the national network of Progressive Era research that prescribed metropolitan solutions for urban problems in cities such as Pittsburgh. The article then examines attempts by the Civic Club of Allegheny County to introduce these theories to Allegheny County, Pennsylvania. The failure of the 1929 Metropolitan Charter is reevaluated, and the implications of these events for current proponents of metropolitanism and political reform are discussed.

  9. Polycentric Metropolitan Form: Application of a ‘Northern’ Concept in Latin America

    Directory of Open Access Journals (Sweden)

    2014-07-01

    Full Text Available Since the mid 20th century, large urban areas in advanced economies have experienced a fundamental transformation from relatively compact monocentric cities towards more extended polycentric metropolitan areas. By now, it is being commented repeatedly, but not investigated systematically that the concept of polycentricity is also adequate to characterise recent metropolitan dynamics in Latin-America.This paper aims to present a few key-issues for a future research agenda into polycentricity in Latin-American metropolitan areas. These elements are identified from a review of existing literature. Since no clear-cut definition and operationalisation of polycentricity exist yet, we distinguish some key-elements of this phenomenon in North America as a frame of reference for this review. It reveals that ‘polycentricity U.S. style’ is at best dawning in Latin-America. In order to achieve a more appropriate picture of polycentricity of Latin American metropolitan areas, our ideas for a research agenda take into account these areas typical economic, social and spatial conditions.

    Over the last few years new practices of spatial strategy making at different planning scales have emerged. At the metropolitan level, such spatial strategies are reminiscent of national and supranational competitive strategies (e.g. EU policies) as well as ratifications of international...... conventions and agreements. A particular feature that metropolitan spatial strategies seem to have in common is the increasingly discretionary planning practices, often, however, within different institutional contexts. It might be assumed, hence, that the regional authorities may adopt different roles...... other themes to be treated at a lower scale, i.e. to the municipal planning authorities. Early observations of the two individual cases suggest that the focus as well as the orientation of these metropolitan plans merge characteristics associated with project-based and strategy-based spatial plans...

    The U.S. Geological Survey (USGS), in cooperation with Federal, State, and local agencies, maintains a long-term network of hydrologic monitoring sites in Kansas. In 2015, the network included about 200 real-time streamgages (hereafter referred to as “gages”), 12 real-time reservoir-level monitoring stations, and 30 groundwater-level monitoring wells. These data and associated analyses provide a unique overview of hydrologic conditions and help improve the understanding of Kansas’s water resources.Real-time data are verified by the USGS throughout the year with regular measurements of streamflow, lake levels, and groundwater levels. These data are used in protecting life and property; and managing water resources for agricultural, industrial, public supply, ecological, and recreational purposes. Yearly hydrologic conditions are characterized by comparing statistical analyses of current and historical water year (WY) data for the period of record. A WY is the 12-month period from October 1 through September 30 and is designated by the year in which it ends.

    As the urbanization continues worldwide more than half of the Earth's population live in the cities (U.N., 2010). Therefore the vulnerability of the urban environment - the living space for millions of people - to the climate change has to be investigated. It is well known that urban features strongly influence the atmospheric boundary layer and determine the microclimatic features of the local environment, such as urban heat island (UHI). Available temperature observations in cities are, however, influenced by the natural climate variations, human-induced climate warming (IPCC, 2007) and in the same time by the growth and structural modification of the urban areas. The relationship between these three factors and their roles in climate changes in the cities are very important for the climatic forecast and requires better understanding. In this study, we made analysis of the air temperature change and urban heat island evolution within Moscow urban area during decades 1970-2010, while this urban area had undergone intensive growth and building modification allowing the population of Moscow to increase from 7 to 12 million people. Analysis was based on the data from several meteorological stations in Moscow region and Moscow city, including meteorological observatory of Lomonosov Moscow State University. Differences in climate change between urban and rural stations, changes of the power and shape of urban heat island and their relationships with changes of building height and density were investigated. Collected data and obtained results are currently to be used for the validation of the regional climate model COSMO-CLM with the purpose to use this model for further more detailed climate research and forecasts for Moscow metropolitan area.

    Heat island is the main product of urban climate, and one of the important problems of twenty-first century. Cities in tropical countries suffer extensively due to the urban heat island effect, and urban climate studies are necessary to improve the comfort level and city planning. Chennai is the tropical city; it is the fourth largest metropolis in India and one of the fastest growing economic and industrial growth centers in South Asia. The spatial distribution of heat intensity in Chennai Metropolitan Area was studied, and the influence of land use and green cover were analyzed in the present work. Mobile measurements were carried out throughout the study area using a grid network to represent various land use patterns of the city. The study revealed some heat and cool pockets within the city limit; the maximum intensities of temperature were noticed in the central core city and north Chennai, which are distinguished for their commercial centers and densely populated residential areas. In morning time, temperature differences between fringes and central parts of heat packets were in the range of 3-4.5 °C. Land use and green cover play a critical role in microclimate and influences it. Green cover has a significant negative correlation with observed microclimate variations. Thus, the study urges city administration, policy makers, and architects to take up effective mitigation and adaptation strategies in the city to make people more comfortable.

  14. Getting to no: how Kansas advocates derailed the Anthem steamroller.

    2002-01-01

    A battle royale has taken shape in Kansas about the future of its Blue Cross and Blue Shield plan. This past February, Kansas Insurance Commissioner Kathleen Sebelius rocked the corporate health care establishment by refusing to allow Anthem Insurance Company to buy the state's independent Blue Cross and Blue Shield plan. Then in June, a state judge overturned her decision. Now the case is headed to appeals court, where Sebelius will seek to have her decision reinstated. At the heart of the legal wrangling is the unprecedented manner in which advocates have asserted consumer interests, raising issues that will persist long after the courts hand down a final ruling. States of Health looks at how consumer advocates have responded to the proposed Blues transaction, a process that has strengthened the health consumer voice in Kansas--and offers important lessons for advocates in other states as well.

    Full Text Available Based on a representative sociological survey with a sample size of 5.000 respondents carried out in 2014, this study investigates the social well-being of people living in the nine largest Hungarian cities and their metropolitan regions, in comparison with survey results from 2005. In the analysis, particular attention has been paid to the Stiglitz Report’s recommendations, to the multi-dimensional nature of social well-being, as well as to the simultaneous consideration of its objective and subjective factors. In the case of the Hungarian metropolitan regions, the eight dimensions of social well-being identified in the Stiglitz Report are explored: (1 material living standards (income, consumption and wealth, (2 health, (3 education, (4 personal activities including work, (5 political voice and governance, (6 social connections and relationships, (7 environment (present and future conditions, and (8 insecurity (of an economic as well as a physical nature. The empirical analysis revealed that the former core–periphery downward slope of metropolitan regions has clearly changed over the past ten years; whereas city centres are still in a favourable position, and the urban outskirts are getting more and more fragmented, suburban zones have undergone significant restructuring. As a result, developed and underdeveloped suburbs have seen an equalisation in terms of social well-being since 2005.

    Full Text Available This study applied remote sensing technology to analyze how rivers in the urban environment affect the surface temperature of their ambient areas. While surface meteorological stations can supply accurate data points in the city, remote sensing can provide such data in a two-dimensional (2-D manner. The goal of this paper is to apply the remote sensing technique to further our understanding of the relationship between the surface temperature and rivers in urban areas. The 2-D surface temperature data was retrieved from Landsat-7 thermal infrared images, while data collected by Formosat-2 was used to categorize the land uses in the urban area. The land surface temperature distribution is simulated by a sigmoid function with nonlinear regression analysis. Combining the aforementioned data, the range of effect on the surface temperature from rivers can be derived. With the remote sensing data collected for the Taipei Metropolitan area, factors affecting the surface temperature were explored. It indicated that the effect on the developed area was less significant than on the ambient nature zone; moreover, the size of the buffer zone between the river and city, such as the wetlands or flood plain, was found to correlate with the affected distance of the river surface temperature.

    Cuffney, Thomas F.; Falcone, James A.

    2009-01-01

    Two nationally consistent multimetric indices of urban intensity were developed to support studies of the effects of urbanization on streams in nine metropolitan areas of the conterminous United States: Atlanta, Georgia; Birmingham, Alabama; Boston, Massachusetts; Dallas-Fort Worth, Texas; Denver, Colorado; Milwaukee-Green Bay, Wisconsin; Portland, Oregon; Raleigh, North Carolina; and Salt Lake City, Utah. These studies were conducted as a part of the U.S. Geological Survey's National Water-Quality Assessment Program. These urban intensity indices were used to define gradients of urbanization and to interpret biological, physical, and chemical changes along these gradients. Ninety census, land-cover, and infrastructure variables obtained from nationally available databases were evaluated. Only variables that exhibited a strong and consistent linear relation with 2000 population density were considered for use in the indices. Housing-unit density (HUDEN), percentage of basin area in developed land (P_NLCD1_2), and road density (ROADDEN) were selected as the best representatives of census, land-cover, and infrastructure variables. The metropolitan area national urban intensity index (MA-NUII) was scaled to represent urban intensity within each metropolitan area and ranged from 0 (little or no urban) to 100 (maximum urban) for sites within each metropolitan area. The national urban intensity index (NUII) was scaled to represent urban intensity across all nine metropolitan areas and ranged from 0 to 100 for all sites. The rates at which HUDEN, P_NLCD1_2, and ROADDEN changed with changes in population density varied among metropolitan areas. Therefore, these variables were adjusted to obtain a more uniform rate of response across metropolitan areas in the derivation of the NUII. The NUII indicated that maximum levels of urban intensity occurred in the West and Midwest rather than in the East primarily because small inner-city streams in eastern metropolitan areas are

    In September 2005, the Commodity Credit Corporation of the U.S. Department of Agriculture (CCC/USDA) initiated periodic sampling of groundwater in the vicinity of a grain storage facility formerly operated by the CCC/USDA at Morrill, Kansas. The sampling at Morrill is being performed on behalf of the CCC/USDA by Argonne National Laboratory, in accord with a monitoring program approved by the Kansas Department of Health and Environment (KDHE 2005), to monitor levels of carbon tetrachloride contamination identified in the groundwater at this site (Argonne 2004, 2005a). This report provides results for the most recent monitoring event, in October 2008. Under the KDHE-approved monitoring plan (Argonne 2005b), groundwater was initially sampled twice yearly for a period of two years (in fall 2005, in spring and fall 2006, and in spring and fall 2007). The samples were analyzed for volatile organic compounds (VOCs), as well as for selected geochemical parameters to aid in the evaluation of possible natural contaminant degradation (reductive dechlorination) processes in the subsurface environment. During the two-year period, the originally approved scope of the monitoring was expanded to include vegetation sampling (initiated in October 2006) and surface water and stream bed sediment sampling (initiated in March 2007, after a visual reconnaissance along Terrapin Creek [Argonne 2007a]). The analytical results for groundwater sampling events at Morrill in September 2005, March and September 2006, March and October 2007, and April 2008 were documented previously (Argonne 2006a,b, 2007b, 2008a,c). Those results consistently demonstrated the presence of carbon tetrachloride contamination, at levels exceeding the KDHE Tier 2 risk-based screening level (5.0 {micro}g/L) for this compound, in a groundwater plume extending generally south-southeastward from the former CCC/USDA facility, toward Terrapin Creek at the south edge of the town.

    2012-01-01

    Because poverty in rural and urban areas of the US often has different causes, correlates and solutions, effective anti-poverty policies depend on a thorough understanding of the ruralness or urbanness of specific places. This paper compares several widely used classification schemes and the varying magnitudes of poverty that they reveal in the US. The commonly used ‘metropolitan/non-metropolitan’ distinction obscures important socioeconomic differences among metropolitan areas, making our understanding of the geography of poverty imprecise. Given the number and concentration of poor people living in mixed-rural and rural counties in metropolitan regions, researchers and policy-makers need to pay more nuanced attention to the opportunities and constraints such individuals face. A cross-classification of the Office of Management and Budget’s metro system with a nuanced RUDC scheme is the most effective for revealing the geographical complexities of poverty within metropolitan areas.

    Cities have become key players in climate change mitigation policy. To develop their climate policies, cities need good assessments of their current and future emissions. We use publically available national datasets to develop an integrated approach for estimating GHG emissions at the metropolitan level over time, between multiple locations, and across sectors. We estimate consistent production-based GHG emissions for the 100 most populated metropolitan areas in the United States in 2014. We find that total 2014 metropolitan CO2 emissions range from 4.1 million metric tons in Lancaster, Pennsylvania to nearly 170 million metric tons in the Houston, Texas; with an overall average of 27 million metric tons. The top 20 absolute emitters and top 20 per capita emitters only overlap for 9 locations. Per capita emissions also show a wide variation: from 5 metric tons per person in the Tucson, Arizona to 65 metric tons per person in the Baton Rouge, Louisiana; with an overall average of 14 metric tons per person. We also compute estimates for 2002 and 2011 and compare to our 2014 emission estimates. Across all locations analyzed, average total emissions increased by 3% and average per capita emissions decreased by 14%. Where possible, we also compare our emission estimates to those reported by the cities in their climate action plans and find an average absolute difference between our estimates and those reported by the cities of 5.6 metric tons CO2 per person, likely due to temporal and scope differences between the two estimates. Our integrated emission estimation approach complements bottom-up approaches typically employed by municipalities and helps practitioners divert their attention and resources away from continuous emission accounting toward more impactful emission mitigation efforts.

    Numerous studies have demonstrated the detrimental influence of residential segregation on poor inner-city residents. This study examines the impact of residential segregation on the welfare of populations in US metropolitan areas using economic growth as the indicator. Panel data of US metropolitan areas spanning 25 years, 1980 2005, are used to analyze the effect of segregation on economic growth. The results show that both racial and skill segregation have a negative impact on short and long-term economic growth, which have increased over time. Further, the negative impact of the variables associated with spatial mismatch is also revealed. The results clearly point to the need for mobility policies that favor non-White households and comprehensive strategies that promote economic opportunities in low-resource communities in the US.

    Full Text Available In metropolitan areas of China, farmland functions have undergone tremendous changes due to rapid urbanization and rising income per capita in the past three decades. This study examines tempo-spatial changes in the farmland functions, using a case study of the Beijing metropolitan area. The results indicate that: (1 during the past three decades, agricultural production experienced two transitions, in the years 1992 and 2003; (2 In terms of spatial differences, farmland functions of food production in Near Suburb significantly weakened. Middle Suburb produced the largest share of vegetables, while Far Suburb had the highest number of recreational farms. This case study may provide insights for large cities in China or other developing countries.

    The metropolitan area of Mexico City is located in a high altitude basin (2 240 m above sea level) at a latitude of 19 degrees 26'13'' North. It has a population of 15 million inhabitants, and the motor vehicles cruising in the city amount to 1.5 million and around 21% of the total industrial activity of the country is sited in the metropolitan area. All this activity has created an acute air pollution problem in the area which, as a direct result, has resulted in decreased visibility and possible health effects.

    Geymen, Abdurrahman; Baz, Ibrahim

    2008-01-01

    Istanbul is the most populated city of Turkey with a population of around 10.58 M (2000) living on around 5,750 km2. In 1980, the population was only 4.7 M and then it has been more than doubled in only two decades. The population has been increasing as a result of mass immigration. An urbanization process continues and it causes serious increases in urban areas while decreasing the amount of green areas. This rapid, uncontrolled, and illegal urbanization accompanied by insufficient infrastructure has caused degradation of forest and barren lands in the metropolitan area, especially through the last two decades. The watershed basins inside the metropolitan area and the transportation network have accelerated the land-cover changes, which have negative impacts on water quality of the basins. Monitoring urban growth and land cover change will enable better management of this complex urban area by the Greater Istanbul Metropolitan Municipality (GIMM). A temporal assessment of land-cover changes of Istanbul has been documented in this study. The study mainly focuses on the acquisition and analysis of Landsat TM and Landsat GeoCover LC satellite images reflecting the significant land-cover changes between the years of 1990 and 2005. Raster data were converted to vector data and used in Geographic Information Systems (GIS). A database was created for Istanbul metropolitan area to plan, manage, and utilize statistical attribute data covering population, water, forest, industry, and topographic position. Consequently an overlay analysis was carried out and land use/cover changes through years have been detected for the case study area. The capability of Landsat images in determining the alterations in the macro form of the city are also discussed.

  12. Office space bacterial abundance and diversity in three metropolitan areas.

    Full Text Available People in developed countries spend approximately 90% of their lives indoors, yet we know little about the source and diversity of microbes in built environments. In this study, we combined culture-based cell counting and multiplexed pyrosequencing of environmental ribosomal RNA (rRNA gene sequences to investigate office space bacterial diversity in three metropolitan areas. Five surfaces common to all offices were sampled using sterile double-tipped swabs, one tip for culturing and one for DNA extraction, in 30 different offices per city (90 offices, 450 total samples. 16S rRNA gene sequences were PCR amplified using bar-coded "universal" bacterial primers from 54 of the surfaces (18 per city and pooled for pyrosequencing. A three-factorial Analysis of Variance (ANOVA found significant differences in viable bacterial abundance between offices inhabited by men or women, among the various surface types, and among cities. Multiplex pyrosequencing identified more than 500 bacterial genera from 20 different bacterial divisions. The most abundant of these genera tended to be common inhabitants of human skin, nasal, oral or intestinal cavities. Other commonly occurring genera appeared to have environmental origins (e.g., soils. There were no significant differences in the bacterial diversity between offices inhabited by men or women or among surfaces, but the bacterial community diversity of the Tucson samples was clearly distinguishable from that of New York and San Francisco, which were indistinguishable. Overall, our comprehensive molecular analysis of office building microbial diversity shows the potential of these methods for studying patterns and origins of indoor bacterial contamination.
