    This paper is about evolution of vulnerability to hazards related to landslides and floods in Northeast of Medellin between 1960 y 1990, connecting urban planning and politics for informal settlements with land occupation processes which have influenced forming of urban vulnerable communities. Case study analysis shows that vulnerability conditions moved following land occupation trajectories and city expansion according to intrinsic adaptation characteristics of settlement inhabitants to environmental conditions, regional processes and dynamics influenced by city politics. Due to accumulation of vulnerability it is interpreted as an environmental impact of processes that influence its configuration which is not static spatial or temporarily neither it correspond to a cause-effect approach but it is complex and connected to other urban environmental expressions

    This work was carried in order to establish an alternative of ecological corridor for structural connection in the districts 1, 2, 3 and 4, north-eastern area of Medellin, aimed to protect existing green land and to decision making or the generation of new soil, using landscape metrics and geoinformatics tools. An area of 400 m 2w as used as a Minimal Mappable Unit (UMC). There were found 296 ha (19.4%) of green areas on the 1,527 ha of study area, 95.4 with predominantly grass cover; while the wooded area, with an area of 26.1 ha, shows the highest isolation (99.1 m), tall scrub, up to 48.7 ha, had the highest aggregation (16.4 m). Priority for conservation was given to eight (8) fragments, selected through the quality index of the fragment (ICF), totaling 26 ha. The corridor was established with a width of 80 m, giving a total area of 73.2 ha, mostly associated with withdrawals from streams.

    Natural disasters of a geodynamic nature can cause enormous economic and human losses. The economic costs of a landslide disaster include relocation of communities and physical repair of urban infrastructure. However, when performing a quantitative risk analysis, generally, the indirect economic consequences of such an event are not taken into account. A probabilistic approach methodology that considers several scenarios of hazard and vulnerability to measure the magnitude of the landslide and to quantify the economic costs is proposed. With this approach, it is possible to carry out a quantitative evaluation of the risk by landslides, allowing the calculation of the economic losses before a potential disaster in an objective, standardized and reproducible way, taking into account the uncertainty of the building costs in the study zone. The possibility of comparing different scenarios facilitates the urban planning process, the optimization of interventions to reduce risk to acceptable levels and an assessment of economic losses according to the magnitude of the damage. For the development and explanation of the proposed methodology, a simple case study is presented, located in north-eastern zone of the city of Medellín. This area has particular geomorphological characteristics, and it is also characterized by the presence of several buildings in bad structural conditions. The proposed methodology permits to obtain an estimative of the probable economic losses by earthquake-induced landslides, taking into account the uncertainty of the building costs in the study zone. The obtained estimative shows that the structural intervention of the buildings produces a reduction the order of 21 % in the total landslide risk.

    This study analyses the impact of the aerial cable car public transport system, locally known as Metrocable, in Medellín (Colombia), on the reduction in crime. As part of the municipal policies of social urbanism, Metrocable has contributed to the social integration of the population in the outlying neighbourhoods, which has increased safety in Medellín. This case is clearly of great interest from the point of view of Criminal Sciences, demonstrating how crime can be combated by using tools beyond ius puniendi. (Author)

    Full Text Available The widespread impact of criminal violence in Latin America, has led it to be ranked as the most dangerous region in the planet by United Nations Office on Drugs and Crime. This situation, combined with the ineffectiveness of the policies implemented so far to mitigate it has generated an intense debate about how, some classic conflict resolution tools as mediation could be explored to contain the violence associated with drug cartels, militias and gangs. However, which are the principal risks to mediate with criminal groups? This article aims to answer this question, using as a case study the city of Medellin. In 2003, the Antioquian capital experienced a dramatic drop in homicides product of aka Don Berna hegemony over all the armed actors operating in the city and subsequent demobilization of his paramilitary group Cacique Nutibara Block, period best known locally as Donbernability. In this way, based on the Colombian case, this work analyzes, under a qualitative approach, the main constraints faced by Governments to mediate with criminal actors to reduce the levels of lethality, usually in exchange for judicial benefits.

    2012-01-01

    Incorporation of environmental variable (greening) in the daily routine of universities has taken force from the ends of the 20th century and nowadays its implementation in Colombia is a fact. This research project evaluated the grade of incorporation of such a variable in mission purposes of three higher education institutions in Medellin (Colombia). It included two different education levels (professional and technical) and used qualitative techniques (interviews to two teachers in each institution, one hour visits to two courses in each institution, and checklists for every visit as well as for the institutional analysis). In all the three study cases the environment is part of the institutional commitments, including their education, research, management processes, as well as activities with the society. This was reflected in the integration of greening in the curricula, the promotion of the research in environmental topics, the interdisciplinary cooperation and the adoption of internal policies. This work identifies some elements to develop the environmental education as a tool to comprehend the society and its environment as a whole; it constitutes a base for discussions, shows the advance of the three studied institutions, and discovers that shortcomings, that should be addressed, still exist.

    The challenge of rural development in the Municipality of Medellin has to do with a political decision to assess processes based on participation and innovation in rural communities. The authorities have the opportunity to establish a territory in order to guarantee stability and consolidation of the populations considering their many activities when the districts are threatened by rampant urban sprawl. The opportunity exists to rebuild civil society in the territory based on cultural identity and to build new spaces without exclusion.

    The transport sector contributes to climate change, and it has been the target of public interventions to improve quality of life and reduce CO_2 emissions. The Medellin metropolitan area (Colombia) has developed a mass transportation system called Metro de Medellin that integrates train lines, a tram line, BRTs, gondola lift systems, a bicycle-sharing system and hybrid buses to reduce traffic and CO_2 emissions. Despite these efforts, pollution is peaking, and the situation requires new plans. The aim of this paper is to quantify the emissions that will be avoided by the implementation of Medellin's Master Plan, the promotion of telecommuting, and the development of a transport energy model for Medellin between 2010 and 2040. The results indicate that combining the promotion of mass transportation and telecommuting could represent 5.65 MTons of CO_2 equivalent avoided by 2040 (9.4% reduction) and estimated total energy savings of 86,575.55 TJ. Therefore, it is necessary to implement complementary policies in order to achieve the commitment assumed by Colombia at the COP 21. The analytical framework used here could be applied to other regions in order to evaluate environmental and energy mitigation strategies, especially in the developing world where similar policies may be in place. - Highlights: • This paper models Aburra's valley transport sector using LEAP model platform. • Impact analysis includes: telecommuting, massive transport investments. • Implementing a combination of the scenarios decreases emissions by 9.4%. • Aggressive transport policies should be made to achieve mitigation targets.

    The state, condition, and tendencies of the agro-ecosystems (AE) of the Paysandu farming center of the Universidad Nacional de Colombia, sede Medellin were characterized and evaluated by means of parameterization and analysis of the various technological receptivity (RT, after the Spanish initials) and technological intensity (IT), based upon a methodological proposal of Velez and Gasto (1999), in terms of AE diversity and of the uses, management, and technological acceptance, techno-structural and hydro-structural endowment, potential productivity and services to the local, regional, and national society. The results showed that the greater part of the center (72%) has very low RT; which does not permit the establishment of mechanized advanced agro-technological management systems (SMA) however, 69.8% of the area is managed with SMA adequate for the restrictions imposed by the RT sixty-two percent of the area of the center, principally under pasture cover for dairy cattle production, is managed with advanced SMA. As a result of the interaction between RT and the SMA employed, six AE were identified, of which three, that represent 69.8% of the area (100.2 ha.), are managed with technologies adequate for their biophysical conditions or with technological receptivity (adequate IT), and the other three, that represent 28,57% of the are (43.1 ha.) ore managed with technologies that do not correspond to their RT conditions (tradition IT) which leads to a deterioration of their biophysical and ecological conditions

    During the last years the Medellin River has been a constant preoccupation for the inhabitants of the Aburra Valley. When the city began to grow took the river as its shaft and all the tailing produced by the domestic action, commercial and industrial were begun to pour of continuous way to its waters, what has caused the degradation that today is observed. Various industries established to what is long of the Medellin River, as are the metal mechanics, those of tanneries, of photographs, paintings and nutritional products, between other. These industries unload its effluents, without no type of treatment, to the river and to its affluent, became these water bodies in receiving of the industrial and domestic liquids effluents of the city. In the present study was sought to determine the presence of some metals in the water bulk and in the sediments of the Medellin River, such as the cadmium, chrome, copper and zinc. The content of these metals plays a role very important in the pollution of the water bodies, upon causing great impact by its toxicity and bio - accumulation. The investigation was accomplished in the section located between the municipalities of Caldas and Copacabana, in four sampling stations during a period of four months, from August until November of 1996

    A total of 6400 noise measurements were taken in downtown Medellin, a 2km x 2km area to characterize noise levels. The area was divided into a grid of 160 blocks with a length 154 m each; 40 measurements were taken in each block Sampling was conducted for 10 days, with simultaneous measurements in four sampling zones selected randomly and with coverage of four sampling periods 7:00-9:00 AM, 9:30-11:30 AM, 12:00 AM-2:00 PM, y 5:00-7:00 PM). The zone between 44 and 49 streets and between 40 and 49 avenues has the maximum average noise level with 74 dBA (decibels in scale A). Four of the noisiest sites were measured during 48 hours continuously by usage of a dosimeter Auto correlation results allowed use of Geo statistics to built isophones for the tour time periods. Isophones plots over imposed on physical layout of the city shows a good correlation between high noise levels and heavy traffic through main avenues (Avenida Oriental, Calle San Juan, Avenida del Ferrocarril, Bazar de los Puentes, Glorieta de la Minorista). Medellin is a noisy city that does not meet existing national regulations. The proposed methodology based on Geo statistics and experimental design is a feasible and comprehensive approach to manage urban noise

    Industrial residues continuing being and economic problem so companies have to assume high costs to manage them. Such is the case of large amounts of fruit residues produced in Medellin, city and surroundings due to a great number of companies of this groindustrial sector. In this work a scan was made in Medellin and the South of Valle de Aburra to know the current problem of these residues. Subsequently a physical-chemistry characterization of the most representative residues with the purpose to propose different alternative uses. The main residues of the interviewed companies come from orange, guava, guanabana and mango. The main valorization processes include compost, worms culture and obtaining chemical products. Only with the interviewed companies, plants of waste valorization could be mounted with prosecution capacity from 9 to 375 ton/month depending on process. If all of the residues generated in Medellin and the South of the Valle de Aburra were used, the capacity of these valorization plants could multiply for 20.

    Empresas varias de Medellin acquired a composting plant (solid waste treatment plant) in the beginning of the 70's. This plant, manufactured in Spain, using French technology, started operation in 1972. It was bought from the machinery Pascua Hermanos y Compania ltda. Spanish consortium. The total investment cost by 1971 was of about $ 20' 000, 000 Colombian pesos. The composting plant was designed as a partial solution (180t/day) to the disposal of about 400 t/days of solid waste disposal in Medellin city. The operation steps of the plant were: collection cars into one of the three hoppers dumped solid waste. Then recyclable material was picked up by hand in a flat conveyor. Hammer mills, where non-crushable material was separated and collected in a reject conveyor, crushed organic material. Afterwards, organic material was screened and was taken by another conveyor into a rotary trommel where manure and organic wastes from the cattle market Plaza de Ferias, and from the municipal slaughterhouse, was planned to be added (this operation was never implemented). The organic portion was separated magnetically from ferrous materials and then conducted to the fermenting aisle, where it stayed for nine days; oxidation was increased by aeration by Archimedes screws. Product coming from the fermenting aisle was discharged in a screening system to classify the compost by granulometry. Again strange elements where taken away from the compost using collision with a ballistic separator. Finally, weight and size, and using belt conveyors and a rotary distributor classified compost, it was disposed in a open field, where it would stay for about thirty days. Social, technical, marketing, economic and administrative problems made difficult the operation of the plant that was closed down in 1985 and fully dismantled in 1988

    Introduction A strong isolated storm complex with bow echo feature crossed northeastern Slovenia in the late afternoon hours and caused extensive damage due to severe wind gusts near 30m/s, excessive rainfalls and large hail. Synoptic situation On June 16th 2009, an upper-level ridge persists over southern Europe while a positively tilted short-wave trough, connected to a complex deep trough over northern Europe, crosses central Europe. Accompanied by this trough, a cold front is extending southwestwards towards the Alps. A relatively strong jet steak wraps around the trough axis and creates strong shear environment which overlaps with a narrow band of unstable airmass present ahead of the coming frontal boundary. Behind this trough/front over central Europe, a high pressure area is developing with stable conditions. Over Slovenia, strong surface heating was on going through the day but lack of near-surface convergence zones, limited moisture and strong capping inversion surpressed any storm initiation in the afternoon. Presentation of research This case study will go through a research of damaging bow echo which caused extensive damage due to severe winds, excessive rainfalls and large hail over much of northeastern Slovenia. Numerous trees were down or uprooted and numerous roofs were blown off or were seriously damaged due to severe wind gusts near or exceeding 30m/s. At first stages, when an isolated severe storm entered Slovenia, it had classic high precipitation supercell features while it transformed into a powerful bow echo later on. Very large hail up to 6cm in diameter was first observed in southeast Austria and near the border with Slovenia, while later on the main threat was very strong wind gusts and intense rainfalls. This research paper will show a detailed analysis of the synoptic situation including analysis of satellite, radar and surface observations. Radar imagery clearly showed isolated storm trailing along the near-surface frontal boundary as

    Full Text Available The article analyzes the repertoire of the national and foreign troupes of opera, zarzuela and theatre, that visited Medellín city (Colombia between 1850 and 1950. The repertoires were composed mostly by plays of foreigners writers, usually Spanish authors, and in some occasions plays by national playwriters. The local government formed a censor boards since 1909 to maintain a control on the content of represented plays, this censor was kept during the whole studied period. They were in charge of vetoing those theatre plays considered immoral or that attempted against the religious precepts of Medellin dwellers, who also, from their place as spectators approved or disapproved the staging through public demonstrations in the function, or by supporting or absence at the season programed by the troupes. The review of the press, of the main cultic magazines of the studied time, of some funds of the Historical Archives of Medellin and of the represented plays, allowed to reflect on the appropriation and circulation of the social representations stating, which only reproduced the practices and accepted experiences by the intellectuals and political elites of the city.

Spatial distribution of the economy is determined by the natural and social conditions. The natural conditions in terms of the economy are of particular significance relief, climatic and hydrographic conditions, soil... According to degree benefits of natural conditions extracted are three relatively homogeneous regions. That is, which rational production of this part of north-eastern Montenegro, can be organized taking into account the natural conditions and the level of socio-economic development. For collocation and the structure of the economy have an important role in the social conditions which the economy is formed. Our research the records clearly pointed to the forefront some very obvious problems: first, is related to the population, especially in workforce, respectively, for the aging; second, that there is a strong migration of people whose intensive processes of differentiation and left behind an unfavorable structure of the population - age and education what the any negative impact on economic development; third, the characteristics of land area, its small size, inadequate and outdated processing, low technical capacity. The natural resources of this part of north-eastern Montenegro, as well as the population as a factor of economic development need to have met: economic, social, developmental organizational and management dimension to be on benefit the present, but also future generations

    Full Text Available This study investigates the spatial economic structure and inequality in Thailand at the national and regional levels, with a particular focus on the Northeastern region in the period from 1987 to 2007. The study has three main points: 1 examination of the economic structure and inequality at the national level and in the Northeastern region according to the Theil index, 2 determination of regional growth centres and satellite towns by using growth pole theory as a conceptual framework and incorporating spatial interaction analysis and 3 analysis of the relationship between regional growth centres and satellite towns with regard to the impact on growth and inequality. The results show that the Northeastern region is definitely the lagging region in the nation, by both gross domestic product (GDP and gross regional product (GRP per capita. It was therefore selected for a case study. Spatial analysis identified Nakhon Ratchasima, Khon Kaen, Udon Thani and Ubon Ratchathani as regional growth centres. Each of them has its own sphere of influence (or satellite towns, and the total area of regional growth centres and satellite towns are classified as sub-regions. The development of regional growth centres has a direct impact on sub-regional economic growth through economic and social relationships: urbanisation, industrial development, per capita growth, the number of higher educational institutes and so on. However, such growth negatively correlates with economic equality among the provinces in a sub-region. The inequality trend is obviously on an upswing. This study suggests that industrial links between regional growth centres and their satellite towns should be improved in order for regional growth centre development to have a consistently desirable effect on both economic growth and equality. Such a strong process means that the growth of regional growth centres will spread, leading to the development of their surrounding areas.

    Full Text Available We analyzed the Fulni-ô medical system and introduced its intermedical character based on secondary data published in the literature. Then we focused on the medicinal plants known to the ethnic group, describing the most important species, their therapeutic uses and the body systems attributed to them. We based this analysis on the field experience of the authors in the project Studies for the Environmental and Cultural Sustainability of the Fulni-ô Medical System: Office of Medicinal Plant Care. This traditional botanical knowledge was used to corroborate the hybrid nature of local practices for access to health. We show that intermedicality is a result not only of the meeting of the Fulni-ô medical system with Biomedicine but also of its meeting with other traditional systems. Finally, we discuss how traditional botanical knowledge may be directly related to the ethnogenesis process led by the Fulni-ô Indians in northeastern Brazil.

    Full Text Available This report focuses on a fatality involving severe dengue fever and melioidosis in a 28-year-old truck driver residing in Pacoti in northeastern Brazil. He exhibited long-term respiratory symptoms (48 days and went through a wide-ranging clinical investigation at three hospitals, after initial clinical diagnoses of pneumonia, visceral leishmaniasis, tuberculosis, and fungal sepsis. After death, Burkholderia pseudomallei was isolated in a culture of ascitic fluid. Dengue virus type 1 was detected by polymerase chain reaction in cerebrospinal fluid (CSF; this infection was the cause of death. This description reinforces the need to consider melioidosis among the reported differential diagnoses of community-acquired infections where both melioidosis and dengue fever are endemic.

    2012-02-01

    Water plays a significant role in wetlands. Floodwater utilisation in wetlands brings a wide range of wetland services, from goods production and water regulation to animal protection and aesthetics related to water supply in wetlands. In this study, the floodwater utilisation values of wetland services were estimated within the Momoge wetland and Xianghai wetland in western Jilin province of northeastern China. From 2003 to 2008, the floodwater diverted from the Nenjiang and Tao'er River is 381 million m3, which translates into a monetary value of approximately 1.35 billion RMB in 2008 (RMB: Chinese Currency, RMB 6.80 = US 1), and the ratio of economic value, eco-environmental value, and social value is 1:12:2. Besides the monetary value of the water itself, excessive floodwater utilisation may bring losses to wetlands; the threshold floodwater utilisation volumes in wetlands are discussed. Floodwater utilisation can alleviate water shortages in wetlands, and the evaluation of floodwater utilisation in wetland services in monetary terms is a guide for the effective use of the floodwater resources and for the conservation of wetlands.

    Full Text Available Abstract Introduction Scedosporium apiospermum is increasingly recognized as a cause of localized and disseminated mycotic infections in near-drowning victims. Case presentation We report the case of a 59-year-old Japanese woman who was a survivor of a tsunami in northeastern Japan and who had lung and brain abscesses caused by S. apiospermum. Initially, an aspergillus infection was suspected, so she was treated with micafungin. However, computed tomography scans of her chest revealed lung abscesses, and magnetic resonance images demonstrated multiple abscesses in her brain. S. apiospermum was cultured from her bronchoalveolar lavage fluid, and antimycotic therapy with voriconazole was initiated. Since she developed an increase in the frequency of premature ventricular contractions, an adverse drug reaction to the voriconazole was suspected. She was started on a treatment of a combination of low-dose voriconazole and liposomal amphotericin B. After combination therapy, further computed tomography scans of the chest and magnetic resonance images of her brain showed a demarcation of abscesses. Conclusions Voriconazole appeared to have a successful record in treating scedosporiosis after a near drowning but, owing to several adverse effects, may possibly not be recommended. Thus, a combination treatment of low-dose voriconazole and liposomal amphotericin B may be a safe and effective treatment for an S. apiospermum infection. Even though a diagnosis of scedosporiosis may be difficult, a fast and correct etiological diagnosis could improve the patient's chance of recovery in any case.

    Game theory enables the predictive study of the behavior of agents that recognize the mutual interdependence of their decisions and act rationally and strategically to maximize their own gains. In this paper, the extractivism of pequi (Caryocar coriaceum Wittm.) and fava d'anta (Dimorphandra gardneriana Tul.) in an area of common use of the semiarid region of northeastern Brazil is described as a model to illustrate a practical application of game theory in the interpretation of the phenomena analyzed in ethnobiological research. Field research was conducted in the Araripe-Apodi National Forest. Semi-structured interviews were conducted with 55 informants recognized as knowledgeable and experienced in the extractivism of pequi and fava d'anta in the region. In the interviews, information that could contribute to the identification and understanding of the focal points of extractivism in the region was surveyed. Data were analyzed under an analytical/descriptive approach using the "content analysis" technique. There was a logic of competitive entrepreneurship around the commercial extractivism of pequi and fava d'anta in the region. Among the extractivists of pequi, one of the main collection rules refers to the prohibition of removing immature fruits by using sticks or shaking the branches. In the extractivism of fava d'anta, no specific rules have been established by collectors, but there is a predominant behavior of withdrawing all available fruits (pods) on a tree in a single visit. In an analysis guided by game theory, the collection decisions adopted by extractivists to maximize gain from the activity can be considered justifiable from the standpoint of economic rationality. The "game of extractivism" of pequi and fava d'anta operates under conditions similar to the "tragedy of the commons." In this game, the non-cooperative solution is converted to the Nash equilibrium. The approach used in this study contributed to the identification of strategies and

    Full Text Available In the present study the authors try to em-phasize the interdependent relations that are established between space and poverty, as well as the modalities through which poverty policies can be optimized and implemented at the territo-rial systems level in accordance to the polycen-tric development model.The f rst goal of the study is to understand the way in which the complexity of the territory, in its structure and relations, inf uences in un-equal ways the territorial pattern of poverty and development. The concept of territorial poverty that we use in the present study transcends the usual connotation of poverty as a simple lack of different kind of resources towards the incapacity of the system to offer a wide range of impulses and solutions to the encountered problems and thus induce a state of underdevelopment.The second goal is to understand in which ways the polycentric development theory can play a role in reducing poverty. In this sense the authors created a poverty index, and based on this index a polycentric development model was created for the North-Eastern region. This poly-centric development model has direct implica-tions for policy makers, as it highlights the areas that require the most attention and the develop-ment pole that should inf uence its development. By taking into consideration the results of this study, the next logical step for policy makers is to implement the necessary measures by consider-ing the relations between the development pole and the underdeveloped area that is under its in-f uence area. In this respect tailor-f t policies and measures can be applied in the effort to reduce poverty levels.

    Full Text Available Objective: compare the quality of life of older adults in Medellin with two groups. Methodology: comparative descriptive study of secondary information source, using the 82,601 records in the Quality of Life Survey of 2008, distributed into three groups: youth, adults and seniors. The analysis was univariate and bivariate, the demographic, economic, social and health security, together with statistical tests of association. Results: older adults account for 9.2%, with female advantage, marital status was married, with a marked difference in the condition of widowhood and 39% did not record any education. Economically it was found that 34.7% engaged in the home, 34.1% are retired and 9.5% continues to work with an average income of a minimum wage. The 71.4% is affiliated to the contributive regime, preventive medical consultations take place at higher rates than young and 31.3% do not. Only 7.3% fell ill last month and his sufferings were hypertension, stress and depression. Conclusions: the older adult with no differences against the other two groups, but age makes it more vulnerable in economic and health conditions have limited the access to opportunities, by not acceding to the demands that the means of production and society require, forgetting their experience and wisdom gained in the course of his life.

    The purpose of this study was to develop a group fuzzy multi-criteria decision-making method to be applied in rating problems associated with water resources management. Thus, here Chen's group fuzzy TOPSIS method extended by a difference technique to handle uncertainties of applying a group decision making. Then, the extended group fuzzy TOPSIS method combined with a consistency check. In the presented method, initially linguistic judgments are being surveyed via a consistency checking process, and afterward these judgments are being used in the extended Chen's fuzzy TOPSIS method. Here, each expert's opinion is turned to accurate mathematical numbers and, then, to apply uncertainties, the opinions of group are turned to fuzzy numbers using three mathematical operators. The proposed method is applied to select the optimal strategy for the rural water supply of Nohoor village in north-eastern Iran, as a case study and illustrated example. Sensitivity analyses test over results and comparing results with project reality showed that proposed method offered good results for water resources projects.

    Objective To analyze cases of violence against transvestites and transsexuals based on their sociodemographic profile. Method Cross-sectional, descriptive research performed in Cajazeiras / Paraíba, consisting of 16 transvestites and transsexuals. Data collection took place in April 2014 and was analyzed descriptively. Results The typology of violence that victimized transvestites and transsexuals were: verbal (91.96%), psychological (58.33%) and physical (33.33%), often between 24 hours and six months preceding the survey. Regarding the spatiality: the street, school and health services were all scenarios of aggression. With respect to the offending agent, the findings point towards neighbors, family members and health professionals. All forms of violence happened between agents and spaces of aggression. Conclusions Violence among this population, silence around the situations of abuse became more pronounced as did its invisibility in the social and institutional context, reflecting the inhibition of human rights and concealment of reality.

    Human papillomavirus (HPV) is an independent risk factor for development of oral squamous cell carcinoma (OSCC). This study aimed to investigate the role of HPV infection and the trend in percentage of HPV-associated OSCC over a 5-year period in northeastern Thailand. In this case-control study, 91 exfoliated oral cell samples and 80 lesion cell samples from OSCC cases and exfoliated oral cells from 100 age/gender-matched controls were collected. HPV infection was investigated by PCR using GP5+/GP6+ primers followed by HPV genotyping using reverse line blot hybridization. Quantitative RT-PCR was used to evaluate HPV oncogene transcription. Temporal trends of HPV infection were evaluated in archived formalin-fixed paraffin-embedded (FFPE) OSCC tissues using in situ hybridization. HPV DNA was found in 17.5% (14/80) of lesion samples from OSCC cases and 29.7% (27/91) of exfoliated oral cell samples from the same cases. These values were significantly higher than in exfoliated oral cell samples from controls (13%, 13/100). HPV-16 was the genotype most frequently found in OSCC cases (92.8%, 13/14 infected cases). Interestingly, HPV oncogene mRNA expression was detected and correlated with OSCC cases (P cases were positive for HPV E6/E7 mRNA expression. There was a trend of increasing percentage of HPV-associated OSCC from 2005 to 2010. This was especially so for females with well-differentiated tumors in specific tongue sub-sites. We suggest that HPV infection plays an important role in oral carcinogenesis in northeastern Thailand. © 2016 Wiley Periodicals, Inc.

    The solute budget in the upper Medellin - Porce river catchment (Colombia) was obtained through chemical and physical water analyses (rainfall and runoff). Samples were taken every two weeks between 04/07/00 and 16/02/01. Balance was carried out for the dissolved ion concentrations in surface waters averaging rainy and dry seasons values. We estimated that runoff contributes with 88% of the principal dissolved solids that flow out of the catchment (H 2 CO 3 , SiO 2 , Ca+2, Na+, Mg+2 K) relative mobility is Ca> Mg> SiO 2 > Na> K. The percentage of dissolved Mg in the Medellin River duplicated the world average for rivers draining plutonic and metamorphic rocks. A chemical weathering rate estimate of 138 kg/ha/yr was derived for the SiO 2 budget and of 48 kg/ha/yr for the sum of major dissolved cations

    Full Text Available Characterization of the insecticidal and hemolytic activity of solubilized crystal proteins of Bacillus thuringiensis (Bt subsp. medellin (Btmed was performed and compared to solubilized crystal proteins of isolates 1884 of B. thuringiensis subsp. israelensis (Bti and isolate PG-14 of B. thuringiensis subsp. morrisoni (Btm. In general, at acid pH values solubilization of the Bt crystalline parasporal inclusions (CPI was lower than at alkaline pH. The larvicidal activity demonstrated by the CPI of Btmed indicated that optimal solubilization of CPI takes place at a pH value of 11.3, in Bti at pH values from 5.03 to 11.3 and in Btm at pH values from 9.05 to 11.3. Hemolytic activity against sheep red blood cells was mainly found following extraction at pH 11.3 in all Bt strains tested. Polyacrylamide gel electrophoresis under denaturing conditions revealed that optimal solubilization of the CPI in all Bt strains takes place at the alkaline pH values from 9.05 to 11.3. An enriched preparation of Btmed crystals was obtained, solubilized and crystal proteins were separated on a size exclusion column (Sephacryl S-200. Three main protein peaks were observed on the chromatogram. The first peak had two main proteins that migrate between 90 to 100 kDa. These proteins are apparently not common to other Bt strains isolated to date. The second and third peaks obtained from the size exclusion column yielded polypeptides of 68 and 28-30 kDa, respectively. Each peak independently, showed toxicity against 1st instar Culex quinquefasciatus larvae. Interestingly, combinations of the fractions corresponding to the 68 and 30 kDa protein showed an increased toxicity. These results suggest that the 94 kDa protein is an important component of the Btmed toxins with the highest potency to kill mosquito larvae. When crystal proteins of Bti were probed with antisera raised independently against the three main protein fractions of Btmed, the only crystal protein that showed

  11. Applications of Low Altitude Remote Sensing in Agriculture upon Farmers' Requests– A Case Study in Northeastern Ontario, Canada

    2014-01-01

    With the growth of the low altitude remote sensing (LARS) industry in recent years, their practical application in precision agriculture seems all the more possible. However, only a few scientists have reported using LARS to monitor crop conditions. Moreover, there have been concerns regarding the feasibility of such systems for producers given the issues related to the post-processing of images, technical expertise, and timely delivery of information. The purpose of this study is to showcase actual requests by farmers to monitor crop conditions in their fields using an unmanned aerial vehicle (UAV). Working in collaboration with farmers in northeastern Ontario, we use optical and near-infrared imagery to monitor fertilizer trials, conduct crop scouting and map field tile drainage. We demonstrate that LARS imagery has many practical applications. However, several obstacles remain, including the costs associated with both the LARS system and the image processing software, the extent of professional training required to operate the LARS and to process the imagery, and the influence from local weather conditions (e.g. clouds, wind) on image acquisition all need to be considered. Consequently, at present a feasible solution for producers might be the use of LARS service provided by private consultants or in collaboration with LARS scientific research teams. PMID:25386696

    With the growth of the low altitude remote sensing (LARS) industry in recent years, their practical application in precision agriculture seems all the more possible. However, only a few scientists have reported using LARS to monitor crop conditions. Moreover, there have been concerns regarding the feasibility of such systems for producers given the issues related to the post-processing of images, technical expertise, and timely delivery of information. The purpose of this study is to showcase actual requests by farmers to monitor crop conditions in their fields using an unmanned aerial vehicle (UAV). Working in collaboration with farmers in northeastern Ontario, we use optical and near-infrared imagery to monitor fertilizer trials, conduct crop scouting and map field tile drainage. We demonstrate that LARS imagery has many practical applications. However, several obstacles remain, including the costs associated with both the LARS system and the image processing software, the extent of professional training required to operate the LARS and to process the imagery, and the influence from local weather conditions (e.g. clouds, wind) on image acquisition all need to be considered.

    Full Text Available Treatment performances of two wastewater treatment plants (WWTPs, located in North-Eastern Algeria (Souk-Ahras and Sedrata were tested using ASM1 model. The model, to be considered as a decision tool for the appropriate management of activated sludge systems, served for the prediction of both WWTP behaviours under different operating conditions. In Sedrata WWTP the first management scenarios is based on an increase of inflow rate, taking into account a new transfer volume from a nearby zone. In a second scenerio, the ultimate flow of 40 000 m3·d-1 is estimated. Regarding Souk-Ahras WWTP, three scenarios were tested. The first tested the impact of an increase of the extraction flow rate and yielded a reduction by 37% of sludge production. The second dealt with the management of the mass budget of substrata and biomass. Finally, the third application was devoted to the estimation of the plant ultimate capacity, estimated to be 60 000 m3·d-1.

    Describing the characteristics, morbidity and risk behaviour of street children from Medellin. This was a descriptive, retrospective study. The medical charts of children aged less than 17 who sought medical attention in five protection institutions in Medellin during 2008 were reviewed. The analysis included descriptive statistics and bivariate analysis. Age was categorised into two groups: boys/girls (0- 12 years) and adolescents (13-17 years). The following characteristicswere found after reviewing 483 medical charts: being male (73.1 %), adolescent (73.1 %) and living in the streets (44.7 %). The most common diagnoses were for infectious and parasite illnesses (21.8 %), factors that affected health status and contact with health services (13.7 %), respiratory diseases (11.8 %). A total of 81.0 % of all children were engaged in psychoactive substance abuse,smoking marijuana being the most common (80.0 %);84.0 % reported engaging in sexual activity. Infectious diseases, sexual activity and usingpsychoactive substances placed this population in a high vulnerability category. This situation demands that local health-policy makers guarantee thispopulation's constitutional right to health, through health-promotion programmes and sexual and reproductive health strategies to prevent disease and psychoactive substance abuse.

    Full Text Available Introduction: Elderly in Medellin present conditions of economic, social, environmental and gen-eral health vulnerability; in nursing homes shows further deterioration of health related quality of life (HRQOL. Objective: To compare the profile of HRQOL of adults over public and private nursing homes in Medellin. Materials and methods: Across-sectional correlational study in 220 elderly selected using probability sampling. WHOQOL-BREF was used and the clinical data of each individual. We assessed scale reliability using Cronbach’s alpha, internal consistency and discriminant validity using Pearson correlations, analyzes of HRQOL were based on summaries measures and frequencies, non-parametric and parametric tests and lineal regression. Results: We found 50 % hypertension, 23.6 % diabetes mellitus, dislipidemia 22.3 % and 15 % osteoporosis. The WHOQOL-BREF showed excellent reliability, internal consistency and discriminant validity, the best score was the psychological health and worst in social relationships. We found no differ¬ences in HRQOL by type of nursing home. The main factors related to HRQL were satisfaction with family support and participation in social groups. Conclusion: We identified some determinants of HRQOL, this demonstrated its multidimensionality; relevant information for further research and for the implementation of public health policies and clinical actions.

    The purpose of this research project was to study the relationship between drug consumption and sexual practices in teenagers in the city of Medellin, Colombia. A transversal studied was designed in order to identify the variables related to having had sexual intercourse under the effects of drugs or alcohol. The sample was made up of 955 teenagers between 14 and 17, who were in 9th, 10th and 11th grades in public and private schools in the city of Medellin. The results show that the prevalence of drug and alcohol influence in sexual intercourse is 43,67%. The most common drugs used for sexual practices are alcohol, marihuana, popper, cocaine and ecstasy. Consuming alcohol or drugs and having sexual practices shows an associated meaningful statistic (p= .001). The more common sexual practices under psychoactive substances are the exploratory ones (caresses and touching) (71%), vaginal penetration (63.67%), oral sex (45.30%) and masturbation (19.59%). Regarding the protection methods during sexual intercourse under drug or alcohol influence 55,9% always use a condom, 37,3% sometimes use it, and 6,8% never do it. This study proves what had been previously established by other research projects that show a high statistic association between drug consumption and sexual practices, but realizes that there is no statistically significant association between sexual practices under the influence of alcohol or drugs and the use or non-use of protective methods, which is the most important finding.

  18. Urban Conflict Vs. Urban “War:” Another “Key” to Read the Conflict in Medellin

    Directory of Open Access Journals (Sweden)

    Ana María Muñoz Guzmán

    2009-06-01

    Full Text Available The urban conflict in Medellin between 1995 and 2002 has been described, fundamentally, as an urban war that can be explained based on the armed political conflict that took place on a national level. The presence of armed actors linked to the Autodefensas Unidas de Colombia (AUC – essentially the “cacique nutibara” block – and the guerilla groups Fuerzas Armadas Revolucionarias de Colombia FARC and Ejercito de Liberacion Nacional ELN, allowed many analysts to explain the conflict in Medellin as a “local expression” of the conflict that took place on the national stage. This article questions this thesis. Instead it suggests that more than an urban “war,” explainable from the national situation and under a conception of state and instrumental/rational politics and power, Medellin has been living inserted into a multiplicity of conflicts that articulate in specific ways, and which involve much more subjective aspects that can be seen in pre-existing neighborhood dynamics from before the “war,” which because of these circumstances we prefer to call urban conflict instead. On the basis on what we found during the investigation and centered on systematic and extensive fieldwork (workshops, interviews, walkthroughs, images, photographs etc. that took four months to complete, we suggest to the experts on urban violence some new “keys” to interpret the conflict in Medellin. One of those is tied to subjective aspects or dimensions of neighborhood life that intervene significantly in conflict dynamics, including political conflicts

    Full Text Available Viticulture in the Mediterranean region has been improved by agronomic methods based on ecophysiological and genetic knowledge of the species and varieties cultivated. Plant growth, yield and quality are highly dependent on climate. Grape sugar content and wine alcohol content are considered as important quality parameters. The objective of our study is to analyse the effects of the current global change on the percentage of alcohol by volume (ABV in red wines from vineyards located in the Montsant Designation of Origin (DO (Priorat County, north-eastern Spain. We present an annual series of percentage of ABV in red wines over the 1984-2008 period (25 years, which is one of the longest series of this viticultural variable in Spain. We do not detect any significant trend of alcohol levels in red wines from the Montsant DO along the 1984-2004 subperiod, but a sharp increase about 1% (by volume is observed after 2004; we statistically checked that the last four years constitute an outlier period in the series. We consider climate evolution over the 1984-2004 period in the study area in order to find some relation with alcohol levels in red wines. Agronomic practices and land cover changes are also taken into account. Results show that the interannual variability of the alcohol levels in red wines are partially explained by temperature and precipitation conditions few days before the vintage. The high percentages of ABV since 2005 may be associated with new trends in viticulture techniques rather than with climate change.

    The purpose of this study was to identify the characteristics of individuals who committed suicide in Medellín between 2008 and 2010, and to identify variables related to the type of events. A retrospective and descriptive analysis was conducted on data provided by the National Institute of Legal Medicine and Forensic Sciences. In addition, a univariate and bivariate analysis was used to identify the sociodemographic and medical-legal characteristics of the deceased. Multiple correspondence analysis was also used in order to establish typologies. The information was analyzed using STATA 11.0. Of the 389 cases occurring between 2008 and 2010, 84.6% (n=329) were men. The male to female ratio was 5:1; 64% of the cases occurred in people aged 18-45 years; 6.7% occurred in children under 18, with hanging being the method most chosen by the victims (48.3%). Exploratory analysis was used to identify a possible association between the use of violent methods and events occurring in the housing and social strata 1, 2 and 3. Some factors could be associated with suicide, providing data that could consolidate health intervention strategies in our population. Copyright © 2013 Asociación Colombiana de Psiquiatría.

    A genome-wide association study (GWAS) suggested that variants on chromosome 17q21 were associated with childhood-onset asthma in white populations. Two replication studies had been conducted in southern Han Chinese population in 2009 and 2012. However, these two Chinese replication results were inconsistent. To further confirm the role of 17q21 common variants, an association study of 17q21 single nucleotide polymorphisms (SNPs) with the risk of childhood-onset asthma was performed in a Han population from northeastern China. In this study, rs3894194, rs12603332 and rs11650680 were genotyped in 435 asthmatic children and 601 healthy controls by using a SNaPshot method. Our data showed that the allelic frequency of rs12603332 and rs11650680 showed significant differences between asthmatic cases and healthy controls, with an odds ratio (OR) of 1.36 [95% confidence interval (CI) 1.12-1.65, P=0.002] and an OR of 1.36 (95% CI 1.07-1.74, P=0.01). Genotype distribution analysis also showed the significant associations of the above two loci with childhood asthma under dominant, recessive and additive model (dominant OR=1.57, 95% CI 1.04-2.36, P=0.032; recessive OR=1.41, 95% CI 1.09-1.83, P=0.009; additive OR=1.97, 95% CI 1.24-3.14, P=0.004; recessive OR=1.50, 95% CI 1.13-1.98, P=0.005). Besides, linear regression analysis showed that rs3894194 and rs12603332 were also significantly associated with asthma phenotypes such as log10 -transformed immunoglobulin E (IgE) level (IU/ml) and log10 -transformed eosinophil percentage (dominant, P=0.04; additive, P=0.01; recessive, P=0.04; recessive, P=0.03; additive, P=0.02). Collectively, our findings suggest that orosomucoid 1-like 3 (ORMDL3) locus on chromosome 17q21 is a risk factor for childhood-onset asthma in northeastern Han Chinese population. Further studies will be needed to elucidate the pathogenesis that ORMDL3 locus predisposes to childhood-onset asthma. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    The northeastern region of Bangladesh often experiences flash flooding during the pre-harvesting period of the boro rice crop, which is the major cereal crop in the country. In this study, our objective was to delineate the impact of the 2017 flash flood (that initiated on 27 March 2017) on boro rice using multi-temporal Landsat-8 OLI and MODIS data. Initially, we opted to use Landsat-8 OLI data for mapping the damages; however, during and after the flooding event the acquisition of cloud free images were challenging. Thus, we used this data to map the cultivated boro rice acreage considering the planting to mature stages of the crop. Also, in order to map the extent of the damaged boro area, we utilized MODIS data as their 16-day composites provided cloud free information. Our results indicated that both the cultivated and damaged boro area estimates based on satellite data had strong relationships while compared to the ground-based estimates (i.e., r ² values approximately 0.92 for both cases, and RMSE of 18,374 and 9380 ha for cultivated and damaged areas, respectively). Finally, we believe that our study would be critical for planning and ensuring food security for the country.

    The solid waste treatment facility of Empresas Varias de Medellln started operation of the 70's. The total investment in equipment and construction by 1971 was of about $ 36'000. 000 Colombian pesos, that by 1997 was valued at more than seven thousand million pesos $7.000'000. 000). The solid waste treatment facility was able to process 180 t/day, generating compost and recyclable by products (textile fibbers. paper, cardboard, glass, plastics, scrap metals) with commercial value. Operating expenses for the facility in 1972 were $2'187.742 to process 53.300 t/year in 296 working days. Revenues from compost and recyclable by products were $ 8 '791.280, with a positive balance of $ 6 '603.538. For those years debt annual payments were $ 3'919.372, giving a yearly profit of $ 2'684.165. Instead of debt payments a yearly charge of $ 7 '315. 240 can be made to account for equipment and construction costs; in addition land rent of $ 500000 per year should be charged to the plant. in this case the operational loss is of $ 1' 397.663 ($ 26/ t) that has to be covered by solid waste service charges. Under these conditions the project is not economically feasible, especially if taking solid wastes to Moravia has not cost at all. Twenty-five years later situation is different: transportation and final disposal costs in Curva de Rodas amount to more than $ 19. 000/t. expected total revenues for a similar project in 1997 could be $2.778' 000.000 and operational expenses for 365 days are estimated at $ 506' 000.000; yearly annual cost for construction and equipment amounts to $1. 411' 000.000 and land rental of $96'000.000 give a profit of close to $765 '000.000. Under these conditions the project is economically feasible and generates a profit: it may be even more attractive if the solid waste company pays a disposal fee, since it is saving room in Curva de Rodas. In order to obtain fully feasibility of the project requires: compost must be improved and positioned in the market

    The aim of this work is at achieving a better understanding of background concentrations of particle materials in suspension (pst) in Medellin. This will allow certain actions and programs for watching and controlling air pollution in this city. Metals analyzed in particle material were: calcium, chromium, copper, iron, magnesium, nickel and lead. Chromium and nickel were not detected in any station and lead was detected in one station only. It is observed that all metals have a large dispersion, excepting total iron in La America and magnesium in point 2 at Belencito, which demonstrates the high temporal variability of these metals in these places. also It is observed that metals do not have a homogenous variation in their breathable fraction (encountered in pm-10) in relation to the total metals (encountered in PST) which is indication of the different sources contribution to the metals concentration and, in general, of PST and PM - 10

    Having a social phobia may lead to consuming alcohol for greater social assertiveness, running the risk of leading to an abuse disorder or alcohol dependence. The aim of the study was to estimate prevalence of pathological comorbidity between social phobia and alcohol consumption in adults of the city of Medellin, and the behavior of comorbidity by gender, age, presence of a father figure in childhood, and education. Secondary analysis of the database of the first Mental Health Population Survey conducted in the city of Medellin in 2011 and 2012 based on the methodology of the World Mental Health Survey guidelines and coordinated by WHO-HARVARD. The lifetime prevalence of abuse and dependence in people with social phobia was 24.1% and 11.2%, respectively. For people with social phobia the prevalence was 13% for abuse and 4.4% for dependence (OR=2.11 for abuse, OR=2.46 for dependence). Annual prevalence of people with social phobia who abused or were dependent on alcohol was 7.8% and 5.9%, respectively, compared to those who do not suffer from this disorder, with a prevalence of 3.4% and 1.7%, respectively (OR=2.39 for abuse and OR=3.57 for dependence). There was significant correlation in the annual and lifetime prevalence between social phobia and the pathological consumption of alcohol. Statistically significant relationships were found for the variables associated with social phobia, however, more work is needed to confirm or refute these associations.

    Salmonella enterica subsp. enterica serovar Dublin ( Salmonella Dublin) is a host-adapted bacterium that causes high morbidity and mortality in dairy cattle worldwide. A retrospective search of archives at the New York Animal Health Diagnostic Center revealed 57 culture-confirmed Salmonella Dublin cases from New York and Pennsylvania in which detailed histology of multiple tissues was available. Tissues routinely submitted by referring veterinarians for histologic evaluation included sections of heart, lungs, liver, spleen, and lymph nodes. Of the 57 S almonella Dublin-positive cases, all were Holstein breed, 53 were female (93%), and 49 (86%) were 90% (45 of 49) of lungs, 90% (28 of 31) of livers, 50% (11 of 22) of spleens, and 62% (18 of 29) of lymph nodes examined had moderate-to-severe inflammation with or without necrosis. Inconstant lesions were seen in 48% (10 of 21) of hearts examined, and consisted of variable inflammatory infiltrates and rare areas of necrosis. We propose a histopathology case definition of Salmonella Dublin in cattle that includes a combination of pulmonary alveolar capillary neutrophilia with or without hepatocellular necrosis and paratyphoid granulomas, splenitis, and lymphadenitis. These findings will assist in the development of improved protocols for the diagnosis of infectious diseases of dairy cattle.

    An understanding of common pathogens and their antibiotic sensitivity patterns is critical for proper management of sepsis in Emergency Department (ED). The goal of the study was to identify common organisms isolated from blood cultures of patients attended to ED and their antimicrobial susceptibility. Beginning from 2002, all cases of positive blood culture collected by the ED, Hospital Universiti Sains Malaysia (HUSM) were recorded and analysed. Over the period of eight years, we documented 995 cases of positive blood cultures. Of these samples, 549 (55.2%) were Gram-negative bacteria; 419 (42.1%) were Gram-positive bacteria; 10 (1.0%) were anaerobic organisms; 10 (1.0%) were fungus; and 7 (0.7%) cases were mixed organisms. Gram-negative bacteria were observed to develop more resistance to antimicrobial agents, especially those commonly used in an outpatient setting with less than 80% sensitivity to ampicillin, cotrimoxazole and ciprofloxacin. By contrast, there has been no marked change in the sensitivity trends of Gram-positive bacteria over the same period. In conclusion, ED physicians are more equipped to initiate empirical antimicrobial therapy especially when dealing with possibility of Gram-negative sepsis.

    Malnutrition results in serious consequences for growth and cognitive development in children. We studied select child and maternal biologic factors, socioeconomic factors, enteric pathogenic burden and gut function biomarkers in 402 children 6-24 months of age in Northeastern Brazil. In this prospective case-control study, not being fed colostrum [odds ratio (OR): 3.29, 95% confidence interval (CI): 1.73-6.26], maternal age ≥18 years (OR: 1.88, 95% CI: 1.10-3.22) and no electric fan (OR: 2.46, 95% CI: 1.22-4.96) or bicycle (OR: 1.80, 95% CI: 1.10-2.95) in the household were positively associated, and higher birth weight (OR: 0.27, 95% CI: 0.19-0.38), larger head circumference (OR: 0.74, 95% CI: 0.66-0.82) and shortness of breath in the last 2 weeks (OR: 0.49, 95% CI: 0.27-0.90) were negatively associated with malnutrition. Subclinical enteric pathogen infections were common, and enteroaggregative Escherichia coli infections were more prevalent in malnourished children (P = 0.045). Biomarkers such as the lactulose-mannitol test, myeloperoxidase, neopterin and calprotectin were highly elevated in both malnourished and nourished children. Nourished children had a better systemic immune response than the malnourished children, as detected by elevated serum amyloid A-1 and soluble cluster of differentiation protein 14 biomarkers (P malnutrition in children. There was a substantial subclinical enteric pathogen burden, particularly with enteroaggregative E. coli, in malnourished children.

Se realizaron mediciones simultáneas de partículas finas (PM2.5 y respirables (PM10 durante el período de febrero a octubre de 2007 en varios sitios de la ciudad de Medellín, capital del departamento de Antioquia, habitada aproximadamente por 2’250.000 personas. Los resultados del análisis muestran, en la mayoría de los casos, una correlación positiva y lineal entre los dos parámetros. La relación (PM2.5/PM10 promedio para los sitios o zonas bajo consideración en este estudio fue de aproximadamente 0.67, valor bastante considerable que hace pensar que probablemente se puede cumplir con la norma anual para PM10, pero no para PM2.5. Los resultados obtenidos identifican las partículas finas como uno de los principales problemas de contaminación en la ciudad de Medellín.This article shows part of the results from the project called: 'Respiratory pathologies in pre-school children and their relation to atmospheric contamination in Medellin,' carried out by Universidad de Medellin and Universidad CES for Medellin Health Secretariat according to contract No. 4700026668, year 2006. Simultaneous measurements of fine particles (PM2.5 and breathable particles (PM10 were made from February to October, 2007 in several sites of Medellin, the capital city of Antioquia State, where about 2,250,000 inhabitants live.

    Historical land use information is essential to understanding the impact of anthropogenic modification of land use/cover on the temporal dynamics of environmental and ecological issues. However, due to a lack of spatial explicitness, complete thematic details and the conversion types for historical land use changes, the majority of historical land use reconstructions do not sufficiently meet the requirements for an adequate model. Considering these shortcomings, we explored the possibility of constructing a spatially-explicit modeling framework (HLURM: Historical Land Use Reconstruction Model). Then a three-map comparison method was adopted to validate the projected reconstruction map. The reconstruction suggested that the HLURM model performed well in the spatial reconstruction of various land-use categories, and had a higher figure of merit (48.19%) than models used in other case studies. The largest land use/cover type in the study area was determined to be grassland, followed by arable land and wetland. Using the three-map comparison, we noticed that the major discrepancies in land use changes among the three maps were as a result of inconsistencies in the classification of land-use categories during the study period, rather than as a result of the simulation model.

    Full Text Available Objective. To define the presence of lung metastasis in bitches with malignant mammary neoplasms. Materials and methods. Thirty female dogs that were attended at Veterinary Hospital (University of Antioquia, Medellin, Colombia were selected for the study. At consultation clinical variables and grade of mammary and inguinal lymph node compromise were registered. Latero-lateral and ventral-dorsal radiographic images of thorax were done for identification of radiographic lesions suggestive of lung metastasis. At surgery biopsies of affected mammary glands were taken for histopathological study and classification of tumors. Data were analyzed by descriptive statistics. Results. The average (± standard error age at clinical diagnosis was 10.87±2.65 year old. French poodle (46.6% cross-breed (13.3% and Schnauzer (10% were the breeds most frequently affected by mammary tumors. The most frequent tumor found was carcinoma (81%, followed by adenoma (8.1%, and other types (10.8%. The most frequently affected mammary glands by tumors were the right and the left inguinal glands (70% and 66.6%, respectively. Five out of 30 bitches (16.6% had lung metastasis according to radiographic examination. From this group of dogs, 4 out of 5 neoplasms (80% were diagnosed as complex carcinoma by histopathology diagnosis. Conclusions. We provide evidence suggesting that complex carcinoma is the most frequent mammary tumor in bitches in our city and it is highly related to lung metastasis.

    Suicide is a public health problem. In Colombia, teenagers are considered a group at high risk for suicidal behavior. To explore the possible association between suicidal behavior and attention deficit hyperactivity disorder in adolescents of Medellin. Observational, cross-sectional, analytical study. The Composite International Diagnostic Interview was applied to a total of 447 adolescents and the sociodemographic, clinical, familiar, and life event variables of interest were analyzed. The descriptive analysis of qualitative variables are presented as absolute values and frequencies, and the age was described with median [interquartile range]. A logistic regression model was constructed with explanatory variables that showed statistical association. Data were analyzed with SPSS® software version 21.0. Of the total, 59.1% were female, and the median age was 16 [14-18] years. Suicidal behavior was presented in 31% of females and 23% of males. Attention deficit was present in 6.3% of adolescents. The logistic regression analysis showed that the variables that best explained the suicidal behavior of adolescents were: female sex, post-traumatic stress disorder, panic disorder, and cocaine use. The diagnosis and early intervention of attention deficit hyperactivity disorder in children may be a useful strategy in the prevention of suicidal behavior in adolescents.

It brings social, health and nutritional consequences for the mother/son binomial. to assess demographic, socioeconomic, food security, health and nutritional status characteristics in a group of pregnant teenagers and their newborns. a cross sectional analytical study was performed in 294 pregnant teenagers in their third trimester of pregnancy enrolled in the prenatal care programs of the public network of hospitals in Medellin-Colombia between 2011 and 2012. Association between the mother's body mass index, iron nutritional status and newborn's weight at birth using explicative variables was assessed. monthly incomes under a minimum salary were associated with low mother's weight and newborns small for gestational age. Low gestational weight was higher in pregnant women under 15 years of age and with a gynecological age under five years. The prevalence of anemia was low in the first trimester and increased at the end of pregnancy; 5.6% had adequate iron reserves. Low weight at birth was associated with infections and mother's low weight in the third trimester of pregnancy. teenage pregnancy is a complex problem associated with negative effects in the nutritional, health and social status of the girl and their newborn.

    This work was carried out in Palmitas rural area of the municipality of Medellin, located between 1.400 and 3.100 m.a.s.l, with temperatures between 10 grades Celsius and 17 grades Celsius and an average precipitation of 2.400 mm./year. In this area an intensive production of vegetables exists, with a use and intensive handling of agro-chemistries. This situation generates problems in the economic development, environment and human health of the region inhabitants. The present research showed that a widespread ignorance exists on the agro-chemistries manipulation; with empiric preparations of mixtures, in the use of not recommended doses and frequencies; which is aggravated by the remiss attention to the technical recommendations, such as, label information, residuals disposition and containers, type of mixtures, and the use of elements for personal protection. This situation is increased by the ignorance on symptoms and handling of intoxications, for the high level of illiteracy, added to the indefiniteness of the basic information about the products. Equally it was found out that the participation of women and children in the processes of agro-chemistries application is exposing them to health problems. This problem is intimately related with cultural, social, economic and technical factors. It was also stated that the peasants of Palmitas use a wide range of toxic products, showing a preference for the fungicidal Maneb (Carbamato) and for the insecticide Dimetoato (Organo-phosphorate).

    In the last twenty years, Differential Synthetic Aperture Radar Interferometry (DInSAR) techniques have been widely used to investigate geological processes, such as subsidence, earthquakes and landslides, through the evaluation of earth surface displacements caused by these processes. In the study of mass movements, contribution of interferometry can be limited due to the acquisition geometry of RADAR images and the rough morphology of mountain and hilly regions which represent typical landslide-prone areas. In this study, the advanced DInSAR techniques (i.e. Small Baseline Subset and Persistent Scatterers techniques), available in SARscape software, are used. These methods involve the use of multiple acquisitions stacks (large SAR temporal series) allowing improvements and refinements in landslide identification, characterization and hazard evaluation at the basin scale. Potential and limits of above mentioned techniques are outlined and discussed. The study area is the Agno Valley, located in the North-Eastern sector of Italian Alps and included in the Vicenza Province (Veneto Region, Italy). This area and the entire Vicenza Province were hit by an exceptional rainfall event on November 2010 that triggered more than 500 slope instabilities. The main aim of the work is to verify if spatial information available before the rainfall event, including ERS and ENVISAT RADAR data from 1992 to 2010, were able to predict the landslides occurred in the study area, in order to implement an effectiveness forecasting model. In the first step of the work a susceptibility analysis is carried out using landslide dataset from the IFFI project (Inventario Fenomeni Franosi in Italia, Landslide Italian Inventory) and related predisposing factors, which consist of morphometric (elevation, slope, aspect and curvature) and non-morphometric (land use, distance of roads and distance of river) factors available from the Veneto Region spatial database. Then, to test the prediction, the

    Traditional environmental risk factors in inflammatory bowel disease (IBD), ulcerative colitis (UC) and Crohn's disease (CD), were examined as part of the retrospective epidemiologic study conducted in Vukovar-Srijem County, north-eastern Croatia in 2010. The geographical variations in the frequency of IBD in Croatia have been observed, which is also the trend in the Central Eastern European region and Europe as a whole, indicating the influence of environmental and lifestyle factors. However, the data on the spread of environmental IBD risk factors are still limited. The purpose of this study was to analyse the traditional environmental risk factors in IBD on our cohort sample, including measles virus infection and vaccination (MMR vaccine-Mumps, Measles, Rubella), tonsillectomy, appendectomy, current and former cigarette smoking and use of oral contraceptives in women. This retrospective, case-control study was performed as a part of a wider epidemiologic study aimed at assessing the incidence, prevalence and clinical expression of IBD, in Vukovar-Srijem County (population: 204,768; 2001), which is a lesser developed part of the continental Croatia that experienced deep demographic changes in the recent past. IBD patients were identified according to the hospital's patient records. There were 119 UC patients and 31 CD patients of a total of 150 patients in the cohort. A total of 150 individuals, volunteers, not having a diagnosis of IBD, age- and sex-matched, were used as the control group. Information on examined risk factors were obtained from all subjects in a previously conducted interview. Patients were contacted personally or by phone and interviewed by a gastroenterologist. There were no differences in the number of smokers, former smokers and non-smokers, between UC and CD patients and the controls, nor in the duration of smoking (years), in current smokers and ex-smokers. Only marginally significant longer time of non-smoking, in ex-smokers was found in

    To characterize maxillofacial fractures due to traffic accidents in patients attending the Hospital Universitario San Vicente Fundación (Medellin-Colombia) from 1998 to 2010. A descriptive study (n =1609) was carried out with information from the medical records of patients meeting the inclusion criteria established by the general objective of the study. The variables consisted of sex, age, year, type and number of fractures, and type of vehicle. A descriptive analysis of the variables was performed and the frequency of fractures due to traffic accidents was calculated according to year and sex. Crude and adjusted odds ratios (aOR) were estimated to establish associations among age, type of vehicle, and the presence of two or more fractures with stratification by sex. The frequency of maxillofacial fractures due to traffic accidents increased in 2007 (men: n=198, women: n=35) and decreased from 2008 to 2010 in both sexes. Fractures were more frequent in persons aged <35 years (80%) and in men (82%). The highest frequency of fractures was observed in motorists. Male users of motorcycles (aOR=1.41; confidence interval 95% [95%CI]: 1.02- 1.94) and bicycles (aOR=1.61; 95%CI: 1.01- 2.56) were more likely to report two or more fractures compared with pedestrians, after adjustment for other variables. Most maxillofacial fractures occurred in men and in motorists. Future studies should analyze other determinants affecting the epidemiology of maxillofacial fractures. Strategies should be designed to improve the use of protective elements and drivers' knowledge and practices. Copyright © 2014 SESPAS. Published by Elsevier Espana. All rights reserved.

    Dumps are sites where the presence of high heavy metal (HM) concentration is a common occurrence, creating the need for implementing restoration processes immediately after their closure. In the 7.6 ha and 45 m high Morro de Moravia dump, arose from the disposal of Medellin solid wastes from 1974 to 1984, previous studies have demonstrated high contents of contaminants, including HM, prompting the need to identify effective mechanisms to implement its restoration. The objective of this study was to evaluate the adaptation, growth and phytoremediation capacity of Bidens pilosa, Lepidium virginicum, Brachiaria decumbens and Arachis pintoi. Content of HM (mg/kg) in Moravia residue matrix went from 17 to 8193 for Pb, 44 to 564 for Cr, 0.2 to 339 for Cd and 77 to 1679 for Ni. Measurements of plant cover, plant height and dry matter production at all plant species studied suggested adequate growth and adaptation to the Moravia dump conditions. Plant absorption of HM showed the pattern Cr > Cd > Ni > Pb. Estimated bioconcentration factors were generally low, and maximum values were 0.36 in A. pintoi (Cr), 2.96 in B. pilosa (Cd) and 0.26 in B. decumbens (Ni). However, our estimations of the phytoremediation potential of the assayed species, suggested they possess low remediation efficiency. Further investigation should be carried out in order to identify more efficient HM accumulators, and to test the use of technologies such as modification of pH, rhizoremediation or the use of genetically enhanced accumulators to increase HM availability to plants

    Several studies have proposed different tools for analyzing the integration of variable renewable energy into power grids. This study applies an optimization tool to model the expansion of the electric power system in northeastern Brazil, enabling the most efficient dispatch of the variable output of the wind farms that will be built in the region over the next 20 years. The expected combined expansion of wind generation with conventional inflexible generation facilities, such as nuclear plants and run-of-the-river hydropower plants, poses risks of future mismatch between supply and demand in northeastern Brazil. Therefore, this article evaluates the possibility of using a fleet of plug-in hybrid electric vehicles (PHEVs) to regularize possible energy imbalances. Findings indicate that a dedicated fleet of 500 thousand PHEVs in 2015, and a further 1.5 million in 2030, could be recharged overnight to take advantage of the surplus power generated by wind farms. To avoid the initial costs of smart grids, this article suggests, as a first step, the use of a governmental PHEV fleet that allows fleet managers to control battery charging times. Finally, the study demonstrates the advantages of optimizing simultaneously the power and transport sectors to test the strategy suggested here. -- Highlights: ► We evaluated the use of plug-in hybrid electric vehicles (PHEV) to regularize possible energy imbalances in northeastern Brazil. ► This imbalance might result from the large-scale wind power penetration along with conventional inflexible power plants in the region. ► We adapted the MESSAGE optimization tool to the base conditions of the Brazilian power system. ► 500 thousand PHEVs in 2015 and 1.5 million in 2030 could be recharged taking advantage of wind energy surplus.

    Municipal waste management often combines different strategies such as recycling, composting, thermal treatment or landfill disposal. In Colombia, urban solid waste is landfill disposed but, industrial and medical wastes are incinerated. The total medical and pathological wastes generated in this zone are about 1643 ton/year from which 1022 ton/year are incinerated in six plants operating in Medellin metropolitan area. As a result, new regulations governing stack gas emissions have been enforced with the aim of reducing air pollutant emissions. Few incinerators are equipped with a gas-cleaning system and thus, most do not have any cleaning system. Medical waste incineration has been recognized as one of the major known sources of polychlorinated dibenzo-pdioxins and polychlorinated dibenzofurans (PCDD/PCDF). To the best of our knowledge, there are not reports about emissions of dioxins and furans from the incineration sector in Colombia. The first aim of this work was to evaluate PCDD/PCDF emissions from the largest incinerators operating in Medellin (Colombia). In this contribution we report results obtained from three incinerators (A, B and C). The incinerated waste in plant A consisted of polymerization sludge, whereas in plants B and C medical and pathological residues were incinerated. Common medical wastes include dirty bandages, culture dishes, plastic, surgical gloves and instruments (including needles) as well as human tissue.

    Dengue fever is a major impact on public health vector-borne disease, and its transmission is influenced by entomological, sociocultural and economic factors. Additionally, climate variability plays an important role in the transmission dynamics. A large scientific consensus has indicated that the strong association between climatic variables and disease could be used to develop models to explain the incidence of the disease. To develop a model that provides a better understanding of dengue transmission dynamics in Medellin and predicts increases in the incidence of the disease. The incidence of dengue fever was used as dependent variable, and weekly climatic factors (maximum, mean and minimum temperature, relative humidity and precipitation) as independent variables. Expert Modeler was used to develop a model to better explain the behavior of the disease. Climatic variables with significant association to the dependent variable were selected through ARIMA models. The model explains 34% of observed variability. Precipitation was the climatic variable showing statistically significant association with the incidence of dengue fever, but with a 20 weeks delay. In Medellin, the transmission of dengue fever was influenced by climate variability, especially precipitation. The strong association dengue fever/precipitation allowed the construction of a model to help understand dengue transmission dynamics. This information will be useful to develop appropriate and timely strategies for dengue control.

    Large numbers of Nearctic shorebirds migrate and winter along the coast of northeastern Brazil, but there is little information on their migratory flows, foraging ecology, and on the structure of the species assemblages that they form with resident shorebirds. We studied these issues on intertidal flats of Baía de Todos os Santos (Bahia), the second largest bay in Brazil. During a full year cycle we carried out weekly bird counts in an intertidal area of 280 ha divided in sectors, where we also measured environmental parameters. The analyses of weekly counts resulted in a detailed phenology of use of the area by shorebirds. Five species were resident and ten were Nearctic migrants. Several of the latter had clear peaks in numbers in March and October, revealing the use of the bay as a stopover during both the north-bound and south-bound migration flows. A canonical correspondence analysis of the relationship between environmental parameters and bird numbers indicated that the foraging bird assemblage could be divided into five main groups, occupying distinct ecological gradients in the study area. The most important factors driving this structure were invertebrate prey abundance, percentage of fine sediments, area of mangrove cover and distance to channels. Our findings imply that maintenance of the diversity of intertidal habitats in this bay is crucial to satisfy the particular habitat requirements of resident and migrant shorebirds using the northeastern coastal regions of Brazil.

    Renewable distributed electricity generation can play a significant role in meeting today's energy policy goals, such as reducing greenhouse gas emissions, improving energy security, while adding supply to meet increasing energy demand. However, the exact potential benefits are still a matter of debate. The objective of this study is to evaluate the life cycle implications (environmental, economic and energy) of distributed generation (DG) technologies. A complementary objective is to compare the life cycle implications of DG technologies with the centralized electricity production representing the Northeastern American context. Environmental and energy implications are modeled according to the recommendations in the ISO 14040 standard and this, using different indicators: Human Health; Ecosystem Quality; Climate Change; Resources and Non-Renewable Energy Payback Ratio. Distinctly, economic implications are modeled using conventional life cycle costing. DG technologies include two types of grid-connected photovoltaic panels (3 kWp mono-crystalline and poly-crystalline) and three types of micro-wind turbines (1, 10 and 30 kW) modeled for average, below average and above average climatic conditions in the province of Quebec (Canada). A sensitivity analysis was also performed using different scenarios of centralized energy systems based on average and marginal (short- and long-term) technology approaches. Results show the following. First, climatic conditions (i.e., geographic location) have a significant effect on the results for the environmental, economic and energy indicators. More specifically, it was shown that the 30 kW micro-wind turbine is the best technology for above average conditions, while 3 kWp poly-crystalline photovoltaic panels are preferable for below average conditions.

    Renewable distributed electricity generation can play a significant role in meeting today's energy policy goals, such as reducing greenhouse gas emissions, improving energy security, while adding supply to meet increasing energy demand. However, the exact potential benefits are still a matter of debate. The objective of this study is to evaluate the life cycle implications (environmental, economic and energy) of distributed generation (DG) technologies. A complementary objective is to compare the life cycle implications of DG technologies with the centralized electricity production representing the Northeastern American context. Environmental and energy implications are modeled according to the recommendations in the ISO 14040 standard and this, using different indicators: Human Health; Ecosystem Quality; Climate Change; Resources and Non-Renewable Energy Payback Ratio. Distinctly, economic implications are modeled using conventional life cycle costing. DG technologies include two types of grid-connected photovoltaic panels (3 kWp mono-crystalline and poly-crystalline) and three types of micro-wind turbines (1, 10 and 30 kW) modeled for average, below average and above average climatic conditions in the province of Quebec (Canada). A sensitivity analysis was also performed using different scenarios of centralized energy systems based on average and marginal (short- and long-term) technology approaches. Results show the following. First, climatic conditions (i.e., geographic location) have a significant effect on the results for the environmental, economic and energy indicators. More specifically, it was shown that the 30 kW micro-wind turbine is the best technology for above average conditions, while 3 kWp poly-crystalline photovoltaic panels are preferable for below average conditions. Second, the assessed DG technologies do not show benefits in comparison to the centralized Quebec grid mix (average technology approach). On the other hand, the 30 kW micro

    The main objective of this article is to determine key factors that may have a significant effect on the verbal abuse, emotional abuse and physical assault of health care workers in north-eastern Turkey. A self-administered survey was completed by 450 health care workers in three well-established hospitals in Erzurum, Turkey. Because of the discrete and ordered nature of the dependent variable of the survey, the data were analysed using four distinctive ordered response models. Results revealed that several key variables were found to be a significant determinant of workplace violence, such as the type of health institution, occupational position, weekly working hours, weekly shift hours, number of daily patient contacts, age group of the respondents, experience in the health sector, training against workplace violence and current policies of the hospitals and the Turkish Ministry of Health.

    The purpose of this research is to establish urban indicators that can support a diagnosis through the application of CDU (scheme of urban inequalities) in the city of Medellin, Colombia, which has a population of about 1,850 inhabitants. Six (6) different quarters, representing all three (3) different social and economic levels, have been chosen in order to analyze and detect three (3) processes of legal and illegal ground occupation, their predominant use and their compatibility in urban accumulation with their associated production of habitation the first process is characterized by an illegal ground occupation with production of non legal habitation and invasion. The second process, the legal ground occupation with housing developed by the formal market, is associated to the private and official sectors. The third and last process, which occurred during the 80's, is characterized by illegal ground occupation and habitation production in steep areas of the city

    Full Text Available Cry11Bb is an insecticidal crystal protein produced by Bacillus thuringiensis subsp. medellin during its stationary phase; this ¶-endotoxin is active against dipteran insects and has great potential for mosquito borne disease control. Here, we report the first theoretical model of the tridimensional structure of a Cry11 toxin. The tridimensional structure of the Cry11Bb toxin was obtained by homology modelling on the structures of the Cry1Aa and Cry3Aa toxins. In this work we give a brief description of our model and hypothesize the residues of the Cry11Bb toxin that could be important in receptor recognition and pore formation. This model will serve as a starting point for the design of mutagenesis experiments aimed to the improvement of toxicity, and to provide a new tool for the elucidation of the mechanism of action of these mosquitocidal proteins.

    The water balance of wetlands plays an integral role in their function. Developments adjacent to wetlands can affect their water balance through impacts on groundwater flow and increased discharge in the area, and they can cause lowering of the wetland water table. A 430 km2 area was selected for groundwater modelling to asses the effect of underground mining on the water balance of wetlands in north-eastern Estonia. A nature conservation area (encompassing Selisoo bog) is within 3 km of an underground oil-shale mine. Two future mining scenarios with different areal extents of mining were modeled and compared to the present situation. Results show that the vertical hydraulic conductivity of the subsurface is of critical importance to potential wetland dewatering as a result of mining. Significant impact on the Selisoo bog water balance will be caused by the approaching mine but there will be only minor additional impacts from mining directly below the bog. The major impact will arise before that stage, when the underground mine extension reaches the border of the nature conservation area; since the restriction of activities in this area relates to the ground surface, the conservation area’s border is not sufficiently protective in relation to underground development.

  19. Public space and ecology in Medellin: of the indexes of square meters for inhabitant, to the system of urban green spaces

    2002-01-01

    This paper constitutes a critic for green urban areas management from the landscape ecology perspective. In the context of urban public space as a reference, the decree No.1504 (1998) about urban public space in the Colombian land planning, and the agreement No.62 (1999) for the Medellin land planning 2000-2010. In the first part the conceptual limitations (from the ecological point of view) of both the decree and land planning in relation lo green areas and city-nature relationships, are highlighted. Green areas are being treated, in fact, as accessory to the urban public spaces and nowadays constitute a functionally disarticulated complex. In the second part the Medellin land planning is examined in detail to show the above-mentioned limitations especially in the absence of an ecological perspective of the urban landscape together with a lack of articulation of private open spaces and green areas. In the third part the new environmental functions of urban green areas are considered, as well as the importance of taking into account and making feasible the interactions among them, under an ecological functioning perspective. Further than an index of square meters per inhabitant. A system of green urban areas and management policies oriented to a greater naturalization are needed. The last part suggests ways of incorporating ecological criteria to the urban environmental management to the urban public space and of course to the planning and management of Medellin urban green areas and its metropolitan area

    To determine the allelic and genotype frequencies of apolipoproteine E (APOE) gene in a representative sample of the adult population of Medellin in 2010. A representative sample of the adult population of Medellin, was obtained by means of a multi-stage, stratified, conglomerate based sampling method. APOE genotyping was carried out on each of the participants. The sampling design was taken into consideration for the frequencies and association analysis. The frequencies of the APOE alleles E2, E3 and E4 were 3.9, 92.0 and 4.1%, respectively. The frequencies of the different APOE genotypes were as follows: 2/2, 0.2%; 2/3, 6.8%; 2/4, 0.6%; 3/3, 85.0%; 3/4, 7.2%, and 4/4, 0.3%. The allelic and genotype frequencies of APOE in an adult population of Medellin did not differ substantially from other series reported in South America. These data are important to determine the real impact of APOE on the population risk of several psychiatric diseases. Copyright © 2013 Asociación Colombiana de Psiquiatría.

    Early detection of febrile illnesses at community level is essential for improved malaria case management and control. Currently, mobile phone-based technology has been commonly used to collect and transfer health information and services in different settings. This study assessed the applicability of mobile phone-based technology in real-time reporting of fever cases and management of malaria by village health workers (VHWs) in north-eastern Tanzania. The community mobile phone-based disease surveillance and treatment for malaria (ComDSTM) platform, combined with mobile phones and web applications, was developed and implemented in three villages and one dispensary in Muheza district from November 2013 to October 2014. A baseline census was conducted in May 2013. The data were uploaded on a web-based database and updated during follow-up home visits by VHWs. Active and passive case detection (ACD, PCD) of febrile cases were done by VHWs and cases found positive by malaria rapid diagnostic test (RDT) were given the first dose of artemether-lumefantrine (AL) at the dispensary. Each patient was visited at home by VHWs daily for the first 3 days to supervise intake of anti-malarial and on day 7 to monitor the recovery process. The data were captured and transmitted to the database using mobile phones. The baseline population in the three villages was 2934 in 678 households. A total of 1907 febrile cases were recorded by VHWs and 1828 (95.9%) were captured using mobile phones. At the dispensary, 1778 (93.2%) febrile cases were registered and of these, 84.2% were captured through PCD. Positivity rates were 48.2 and 45.8% by RDT and microscopy, respectively. Nine cases had treatment failure reported on day 7 post-treatment and adherence to treatment was 98%. One patient with severe febrile illness was referred to Muheza district hospital. The study showed that mobile phone-based technology can be successfully used by VHWs in surveillance and timely reporting of fever

  2. The effect of secondary apatite on the initial 87Sr/86Sr ratio determination in granitic rocks: a case study of the Tadamigawa pluton, northeastern Japan

    Apatite is a major accessory mineral in igneous rocks. Because Rb contents in apatite are very low, 87Sr/86Sr ratios of magmatic apatite are useful to estimate the initial 87Sr/86Sr ratio (SrI) of igneous rocks. Secondary post-magmatic event such as hydrothermal alteration may also crystallize secondary apatite, which may inhibit the estimation of SrI of igneous rocks. In this study, we examine the effects of secondary apatite on the initial 87Sr/86Sr ratio determination of granitic rocks by using acid leaching technique. Leached apatite samples were first separated from the whole rock powder as a heavy mineral fraction by heavy liquid technique, and the heavy mineral fraction was then leached by 3 M HNO3. The isotopic ratios of Sr and the concentrations of Rb and Sr were analyzed by TIMS and ICP-MS at Kochi Core Center, respectively. The Tadamigawa Older-stage granites, which locate in the Taishaku Mountains at the northeastern part of Japan, intrude into the Ashio Jurassic complex, and the ages of these rocks are late Cretaceous to Paleogene. The U-Pb ages of zircon and the K-Ar ages of biotite for these rocks are c. 100 Ma [1, 2]. Rb-Sr whole-rock isochron age of the pluton is 96.5 ± 1.3 Ma (SrI = 0.70534 ± 0.00003) and it is concordant with other radiometric ages. Rb-Sr mineral isochron ages range from 84.4 to 97.3 Ma and these ages are relatively younger than the Rb-Sr whole-rock isochron age. The difference among radiometric ages may reflect the difference of the closure temperature in each isotopic system. The Tadamigawa Older-stage granites have SrI for Rb-Sr mineral isochron range from 0.7053 to 0.7061 and are very similar to that (0.70534) for Rb-Sr whole-rock isochron. These may suggest that the Tadamigawa Older-stage granites are generated from same parental magma. However, 87Sr/86Sr ratios of the leached apatite samples were 0.70544-0.70856 and are relatively higher than SrI obtained from the Rb-Sr mineral isochrons (0.7053-0.7061). This result

    2007-01-01

    The paper constitutes a reflection around the urban landscape, whit reference to Medellin, likewise around the landscaping and ecological potential that the city has along its terrain, its empty lots, without urbanizing, and especially, thanks to the tree plantation that its streets display. It is questioned the absence of a landscaping dimension in the urban planning; the increasing deterioration of the panoramic qualities; and the gradual loss of green spaces. At the same time, it is emphasized the importance that such tree planting has in the landscape, from the visual, social and environmental point of view. The work discusses the tendency to the artificiality of tree planting on sidewalks and vial road separators, raising conceptual limitations associated to the scale tree to tree, to the lack of incorporation of ecological landscape relations related to its handling, and to the landscaping approach within the framework of the urban designing. The reflection leans on data of the concrete situation, suggesting the complementary role that the vegetation could accomplish in streets and avenues with a perspective of ecological connectivity of the landscape

    Shift work is common in health care settings and has been hypothesized as a risk factor for being overweight or obese. We examined the relation between shift work and being overweight or obese, adjusting for stress and lifestyle habits in Colombian health care workers. The aim of this study was to assess the association between shift work and being overweight/obese in employees of a health care setting in Medellin, Colombia. This cross-sectional study was carried out among 200 workers in a health care setting. Participants completed a demographic, occupational, work-related stress and life style questionnaire. Their Body Mass Index (BMI) and waist to hip ratio were also measured. The study sample consisted of 160 (80%) females and 40 (20%) males. Mean age was 35.1±9.1 years and mean BMI was 25±3.9. After adjusting for potential confounders, multivariate logistic regression revealed no statistically significant association between being overweight, being obese or waist to hip ratio and shift work; 95% CI OR: 1.08 (0.62-1.89), 1.33 (0.44-3.99) and 1.2 (0.8-1.9), respectively. Day workers were statistically more likely to smoke, work more hours, and have a higher educational level than shift workers. No significant associations between shift work and being overweight/obese were observed in health care workers in a Colombian setting. These findings need to be confirmed through longitudinal studies.

    The training strategies targeted at men so as to reflect on the cultural patterns of patriarchy are an alternative in the promotion of human rights, the prevention of violence towards women and the mainstreaming of gender equality in public policies. With a socio-critical pedagogical approach, we conducted a Training Certification Program in gender equality and gender-sensitive masculinities, for a group of 76 male civil servants and civic leaders in the Colombian city of Medellin, for the purpose of questioning their gender socialization in the patriarchal model, directed towards the development and execution of social, educational or communications projects. The projects proposed by the participants criticize the andro-centric, sexist and discriminatory discourses regarding women that circulate in a manner predominant in their academic, workplace and family ambits, with a gender political commitment and respect for diversity.

    Full Text Available Ten possible cases of tropical spastic paraparesis (TSP in Northeastern Brazil (Ceará are presented. They show the typical symptoms and signs of TSP consisting of weakness of the lower limbs, spastic gait, hiperreflexia, bladder dysfunction and variable signs of posterior columns impairment. The laboratory examinations excluded other compressive, infective, degenerative or demyelinating lesions of their spinal cord. Our patients age ranged from 21 to 59 years, all were of black origin and all were of lower social class. There was a slight preponderance of females. An etiological implication of a retrovirus (HTLV-I has been shown for TSP, but for lack of technical conditions we could not determine it in our patients, and that stands as our subsequent step in those and further cases.

    Colonization plays a major role in the epidemiology and pathogenesis of Staphylococcus aureus infections. The child population is one of the most susceptible to colonization; however, community and children studies are limited in Colombia. To assess the clonal relationship of S.aureus strains isolated from colonized children in eight day care centers (DCCs) from Medellin and to determine the presence of epidemiological characteristics in these populations. An observational cross-sectional study was conducted on a sample of 200 children aged from 6 months to 5 years attending eight DCCs in Medellin, Colombia, during 2011. Nasal samples were collected from each nostril. The isolates species and methicillin resistance were molecularly confirmed using nuc and mec genes. Genotypic analysis included SCCmec typing, spa typing, PFGE and MLST. Epidemiological information was obtained from the parents and analyzed using the statistics program SPSS 21.0 RESULTS: The colonization frequency in DCCs ranged from 16.7% (n=3) to 53.6% (n=15). Genetically related isolates were identified inside four DCCs. Half (50%) of the isolates were grouped in 3 clusters, which belonged to the clonal complexes CC45, CC30, and CC121. Molecular typing of isolates from colonized children and comparison among DCCs showed the spread of colonizing strains inside DCCs in Medellin; predominantly the CC45 clone, a successful child colonizer.

    From 1949 through 1989 nuclear weapons testing carried out by the former Soviet Union at the Semipalatinsk Nuclear Test Site (SNTS) resulted in local fallout affecting the residents of Semipalatinsk, Ust-Kamenogorsk and Pavlodar regions of Kazakstan. To investigate the possible relationship between radiation exposure and thyroid gland abnormalities, we conducted a case review of pathological findings of 7271 urban and rural patients who underwent surgery from 1966-96. Of the 7271 patients, 761 (10.5%) were men, and 6510 (89.5%) were women. The age of the patients varied from 15 to 90 years. Overall, a diagnosis of adenomatous goiter (most frequently multinodular) was found in 1683 patients (63.4%) of Semipalatinsk region, in 2032 patients (68.6%) of Ust-Kamenogorsk region and in 1142 patients (69.0%) of Pavlodar region. In the period 1982-96, as compared before, there was a noticeable increase in the number of cases of Hashimoto's thyroiditis and thyroid cancer. Among histological forms of thyroid cancer, papillary (48.1%) and follicular (33.1%) predominated in the Semipalatinsk region. In later periods (1987-96), an increased frequency of abnormal cases occurred among patients less than 40 years of age, with the highest proportion among patients below 20 in Semipalatinsk and Ust-Kamenogorsk regions of Kazakstan. Given the positive findings of a significant cancer-period interaction, and a significant trend for the proportion of cancer to increase over time, we recommend more detailed and etiologic studies of thyroid disease among populations exposed to radiation fallout from the SNTS in comparison to non-exposed population.

    Dengue is an important public health problem worldwide. A vaccine has recently been licensed in some countries of Latin America and Asia. Recommendations for dengue vaccine introduction include endemicity and a high serological prevalence of dengue in the territories considering its introduction. A community-based survey was conducted to estimate dengue seroprevalence and age-specific seroconversion rates in a community in Medellin, Colombia, using a dengue serological test (IgG indirect ELISA). Residents were selected at random and were first screened for dengue infection; they were then followed over 2.5 years. A total of 3684 individuals aged between 1 and 65 years participated in at least one survey. The overall dengue seroprevalence was 61%, and only 3.3% of seropositive subjects self-reported a past history of dengue. Among dengue virus (DENV)-naïve subjects with more than two visits (n=1002), the overall seroconversion rate was 8.7% (95% confidence interval 7.3-10.4) per 1000 person-months, over the study period. Overall, the mean age of DENV prevalent subjects was significantly higher than the mean age of seroconverted subjects. Specifically, DENV seropositivity over 70% was observed in participants over 21 years old. Serotype-specific plaque-reduction neutralization tests (PRNT) revealed that all four dengue serotypes were circulating, with DENV4 being most prevalent. These laboratory-based findings could inform dengue vaccine decisions, as they provide age-specific seroprevalence and seroconversion data, evidencing permanent and ongoing dengue transmission in the study area. This study provides evidence for the existing rates of secondary and heterotypic responses, presenting a challenge that must be addressed adequately by the new vaccine candidates.

    The Cinque Torri group (Cortina d'Ampezzo, Italy) is an articulated system of unstable carbonatic rock monoliths located in a very important tourism area and therefore characterized by a significant risk. The instability phenomena involved represent an example of lateral spreading developed over a larger deep seated gravitational slope deformation (DSGSD) area. After the recent fall of a monolith of more than 10 000 m 3, a scientific study was initiated to monitor the more unstable sectors and to characterize the past movements as a fundamental tool for predicting future movements and hazard assessment. To achieve greater insight on the ongoing lateral spreading process, a method for a quantitative analysis of rotational movements associated with the lateral spreading has been developed, applied and validated. The method is based on: i) detailed geometrical characterization of the area by means of laser scanner techniques; ii) recognition of the discontinuity sets and definition of a reference frame for each set, iii) correlation between the obtained reference frames related to a specific sector and a stable external reference frame, and iv) determination of the 3D rotations in terms of Euler angles to describe the present settlement of the Cinque Torri system with respect to the surrounding stable areas. In this way, significant information on the processes involved in the fragmentation and spreading of a former dolomitic plateau into different rock cliffs has been gained. The method is suitable to be applied to similar case studies.

    Improved indoor air quality (IAQ) is one of the critical components of green building design. Green building tax credit (e.g., New York State Green Building Tax Credit (GBTC)) and certification programs (e.g., Leadership in Energy & Environmental Design (LEED)) require indoor air quality measures and compliance with allowable maximum concentrations of common indoor air pollutants. It is not yet entirely clear whether compliance with these programs results in improved IAQ and ultimately human health. As a case in point, annual indoor air quality measurements were conducted in a residential green high-rise building for five consecutive years by an industrial hygiene contractor to comply with the building's GBTC requirements. The implementation of green design measures resulted in better IAQ compared to data in references of conventional homes for some parameters, but could not be confirmed for others. Relative humidity and carbon dioxide were satisfactory according to existing standards. Formaldehyde levels during four out of five years were below the most recent proposed exposure limits found in the literature. To some degree, particulate matter (PM) levels were lower than that in studies from conventional residential buildings. Concentrations of Volatile Organic Compounds (VOCs) with known permissible exposure limits were below levels known to cause chronic health effects, but their concentrations were inconclusive regarding cancer health effects due to relatively high detection limits. Although measured indoor air parameters met all IAQ maximum allowable concentrations in GBTC and applicable LEED requirements at the time of sampling, we argue that these measurements were not sufficient to assess IAQ comprehensively because more sensitive sampling/analytical methods for PM and VOCs are needed; in addition, there is a need for a formal process to ensure rigor and adequacy of sampling and analysis methods. Also, we suggest that a comprehensive IAQ assessment should

    The population growth and the urban concentration involve a sustained increment in water demand, which requires an adequate effort and management of the ecosystems that provide the liquid to guarantee a plenty future offer. The performance of the entities in charge of the management of such ecosystems and the results obtained in the basins that supply drinkable water to two cities in Colombia are analyzed; financial topics and their relation with the local community are considered. Management is delegated to governmental entities, whose work is insufficient and unsatisfactory. Thus, application of economical, legal and social tools is proposed in order to improve ecosystem's conservation and life quality of farmers that inhabit in their influence areas, partially transferring management to the local community's orbit.

  17. Environmental education strategies for decentralized schools in the Colombian educative system: the Medellin experience

    2008-02-01

    Full Text Available Environmental education is a condition to enable an attitudinal and aptitudinal generation of change, a condition that facilitates the balance between man and his surroundings. Environmental education needs the support of almost every discipline. In order to solve environmental problems, one must count on the active participation of a wide set of people and institutions. This article examines environmental education in Colombia focusing on the case of training programs, making emphasis on a case study that took place in Medellín, capital of the department of Antioquia. Results show there is a lack of clear conceptualization about the reasons and ultimate purposes concerning why environmental education is finally accomplished. That situation has conducted to the formulation of objectives and strategies that are too general to be properly fulfilled, and the implementation of detailed, and isolated actions.Lack of coordination between institutions and groups has resulted in duplicity of functions and efforts, which in turn result in a far from rational use of scarce resources. The conclusion is that environmental education in Colombia is still inefficient and must advance to higher levels, taking into account these three main perspectives: environmental, educative and pedagogic.

  18. Northeastern states sharpen biomass focus

    Wood energy use in the northeastern region of the USA currently replaces an estimated annual equivalent of 45--50 million barrels of oil. Including municipal wastes and recovered methane emissions for regional landfills, total biomass contribution to the energy economy is over 70 million barrels of oil equivalent annually. A reasonable consensus suggests wood alone could replace the equivalent of over 300 million barrels of oil each year on a sustainable basis over the next two decades. Beyond energy security, over 60,000 total jobs are now provided in the region by the wood energy industry. Over 375,000 total jobs could be generated by the wood energy industry, about 65,000 in the harvesting, transportation, and end-use operations of the wood energy industry. Biomass producers must be committed to sustainable development by necessity. Sound forest management practices that keep residual stand damage from wood harvesting to a minimum can create positive impacts on the region's forest. When combined with a balanced energy policy, the conditional use of wood energy can play a modest, but significant, role in reducing air emissions. Depletion of traditional energy resources creates open-quotes bubbleclose quotes benefits which will be exhausted after a generation. Sustainable development of biomass can create inexhaustible wealth for generations, and does not pose the risk of sudden ecological disruption. While the choice between policy options is not mutually exclusive, the interrelationship between energy security, economic growth and environmental quality clearly favors biomass. The environmental benefits and the economic growth impacts of biobased products produced by the northeastern states are considerable. The 11 states located in the northeastern USA should intensify their efforts to work with industry and investors to expand markets for industrial biobased products, either produced from local feedstocks or manufactured by companies operating in the region

    Full Text Available Objective: To explore the possible association between the risk of suicide, depression, consumption of psychoactive and family dysfunction in school adolescents. Methodology: It was administered a self-administered survey to a random sample of 779 adolescents to assess the risk of suicide, depression, psychoactive substance use and family dysfunction, the instruments were used ISO-30, CDI-LA-II CIDI and Family Apgar respectively. The analysis used the technique of case-control method. Results:The prevalence of suicide risk was between 23.0% and 26.5%. Depression and family dysfunction were positively associated with suicide risk, with a disparity ratio of 4.3 and 2.0 respectively. Conclusions: The results show the magnitude of a problem that must take into account the educational authorities, the municipal administration and parents. A priority is to strengthen programs for adolescent depression screening, and also require to the State better treatments for depression (not just limited to the drug. We must promote the strategy of school parents in educational institutions, emphasizing issues related to mental health and stress the importance of communication, cooperation, affection and respect among family members.

    Full Text Available The observation in the city of Medellín within the framework of urban history generated a surprising picture of subjects in hygiene and public health, among which we found the case of mental illness and the control systems proposed by civilian authorities and doctors. In Medellín, between 1880 and 1950, the modernization process went on, turning its pole of attraction on population displacements to the interior of the province of Antioch. As a result of Railroad I, there was a massive mobility of population from the neighboring towns, including some mentally ill people. At the end of the 19th century, the authorities created a house of asylum for these people, which became the Mental Hospital in the middle of the 20th century. The isolation of the mentally ill people reports both medical authority and the beginning of the constitution process and institutionalization of the psychopathology and medicalization of mental diseases in Antioquia at the beginning of the 20th century.

    La observación sobre la ciudad de Medellín en el contexto de la historia urbana, generó un sorprendente cuadro de temas sobre higiene y salud pública, entre los que encontramos el caso de los alienados mentales y los dispositivos de control propuestos por las autoridades civiles y los médicos. De 1880 hasta 1950 Medellín vivió el proceso de modernización, que la convirtió en polo de atracción de los desplazamientos de población al interior de la provincia de Antioquia. El Ferrocarril garantizó desde los pueblos vecinos la movilización masiva de población, entre la que llegaron no pocos alienados mentales. A finales del siglo XIX, las autoridades crearon la Casa de Alienados para dar asilo a estas personas, esta institución se convirtió a comienzos del siglo XX en Manicomio Departamental y a mediados del siglo XX en el Hospital Mental de Antioquia.

    SUMMARY A diphtheria outbreak occurred from February to November 2011 in the village of Kimba and its surrounding settlements, in Borno State, northeastern Nigeria. We conducted a retrospective outbreak investigation in Kimba village and the surrounding settlements to better describe the extent and clinical characteristics of this outbreak. Ninety-eight cases met the criteria of the case definition of diphtheria, 63 (64.3%) of whom were children aged diphtheria. None of the 98 cases received diphtheria antitoxin, penicillin, or erythromycin during their illness. The overall case-fatality ratio was 21.4%, and was highest in children aged 0-4 years (42.9%). Low rates of immunization, delayed clinical recognition of diphtheria and absence of treatment with antitoxin and appropriate antibiotics contributed to this epidemic and its severity.

    Full Text Available Repeated exposure to human immunodeficiency virus (HIV does not always result in seroconversion. Modifications in coreceptors for HIV entrance to target cells are one of the factors that block the infection. We studied the frequency of Delta-32 mutation in ccr5 gene in Medellin, Colombia. Two hundred and eighteen individuals distributed in three different groups were analyzed for Delta-32 mutation in ccr5 gene by polymerase chain reaction (PCR: 29 HIV seropositive (SP, 39 exposed seronegative (ESN and 150 individuals as a general population sample (GPS. The frequency of the Delta-32 mutant allele was 3.8% for ESN, 2.7% for GPS and 1.7% for SP. Only one homozygous mutant genotype (Delta-32/Delta-32 was found among the ESN (2.6%. The heterozygous genotype (ccr5/Delta-32 was found in eight GPS (5.3%, in one SP (3.4% and in one ESN (2.6%. The differences in the allelic and genotypic frequencies among the three groups were not statistically significant. A comparison between the expected and the observed genotypic frequencies showed that these frequencies were significantly different for the ESN group, which indirectly suggests a protective effect of the mutant genotype (Delta-32/Delta-32. Since this mutant genotype explained the resistance of infection in only one of our ESN persons, different mechanisms of protection must be playing a more important role in this population.

  6. In vivo binding of the Cry11Bb toxin of Bacillus thuringiensis subsp. medellin to the midgut of mosquito larvae (Diptera: Culicidae

    Full Text Available Bacillus thuringiensis subsp. medellin produces numerous proteins among which 94 kDa known as Cry11Bb, has mosquitocidal activity. The mode of action of the Cry11 proteins has been described as similar to those of the Cry1 toxins, nevertheless, the mechanism of action is still not clear. In this study we investigated the in vivo binding of the Cry11Bb toxin to the midgut of the insect species Anopheles albimanus, Aedes aegypti, and Culex quinquefasciatus by immunohistochemical analysis. Spodoptera frugiperda was included as negative control. The Cry11Bb protein was detected on the apical microvilli of the midgut epithelial cells, mostly on the posterior midgut and gastric caeca of the three mosquito species. Additionally, the toxin was detected in the Malpighian tubules of An. albimanus, Ae. aegypti, Cx. quinquefasciatus, and in the basal membrane of the epithelial cells of Ae. aegypti midgut. No toxin accumulation was observed in the peritrophic membrane of any of the mosquito species studied. These results confirm that the primary site of action of the Cry11 toxins is the apical membrane of the midgut epithelial cells of mosquito larvae.

    Northeastern Brazil is the most seismic active region in the country. Some earthquakes with magnitude above 5.0 and intensity VII MM associated with swam-like seismic activity lasting for many years are a serious social concern. Since the 1980's macroseismic and instrumental surveys have been carried out in this region and they are an important data archive which allows the composition of a reliable catalogue of seismic activity for this region. Among the many scientific results it was possible to identify the main seismogenic areas, obtain reliable hypocentres and focal mechanisms. As a consequence, it was possible also to analyse the relationship between seismicity and geological features. It was also possible to determined maximum horizontal stress direction for the region. An important induced seismic activity case has also been reported in the area as being a classical example of pore pressure diffusion triggering mechanism. The majority of the results were obtained using analogic data. Recently, a new research project is being conducted and will allow us to provide a regional scale monitoring with 6 broad-band stations and a new portable six station digital seismic network equipped with short- period sensors. Thus, with the continuous seismic activity in the area we trust that the results of this project will increase the present knowledge of seismic activity in northeastern Brazil.

    Psoriasis is an autoimmune disease with genetic and environmental factors. Based on the roles of STATs (signaling transducers and activators of transcription) in autoimmune diseases, it is assumed STAT gene polymorphisms are associated with psoriasis. To study the association between STAT gene polymorphisms and psoriasis in the northeastern Chinese population. Eight single-nucleotide polymorphisms were genotyped: rs2293152, rs3816769, rs4796793, and rs744166 in STAT3, rs7574865 and rs3024866 in STAT4, and rs324011 and rs3024974 in STAT6, using SNaPshot methods. The genotype, allele, and haplotype frequencies were compared between 400 psoriasis patients and 398 healthy individuals in northeastern China. rs744166GG in STAT3 and rs7574865TT in STAT4 had higher frequencies in the case than the control group, suggesting these 2 genotypes increase the susceptibility to psoriasis (p < 0.05). Three haplotypes (H3, H6, and H7) were found to be associated with psoriasis in the study (p < 0.05). These results indicate a role of STAT genes in the pathogenesis of psoriasis. © 2017 S.

In particular, Canis familiaris (or domesticated dogs) are believed to be a major urban reservoir for the parasite causing the disease Leishmania. The average number of human VL cases was 58 per year in the state of Sergipe. The city of Aracaju, capital of Sergipe in Northeastern Brazil, had 159 cases of VL in humans. Correlatively, the percentage of serologically positive dogs ...

    A comprehensive investigation of the typhoon induced upper ocean processes and responses off northeastern Taiwan was conducted. Using the Regional Ocean Modeling System, the upper ocean responses of all typhoons striking Taiwan between 2005 and 2013 were simulated. In addition to Kuroshio intrusion, the present study demonstrates another important mechanism of typhoon induced near-inertial currents over the continental shelf of East China Sea, which can also trigger a distinct cooling (through entrainment mixing) within this region. Results indicate that the processes of typhoon inducing distinct cooling off northeastern Taiwan are conditional phenomena (only ∼12% of typhoons passing Taiwan triggered extreme cooling there). Subsequently, by executing a series of sensitivity experiments and systematic analyses on the behaviors and background conditions of all those typhoon cases, key criteria determining the occurrences of cooling through both mechanisms were elucidated. Occurrences of cooling through the Kuroshio intrusion mechanism are determined mainly by the strength of the local wind over northeastern Taiwan. A distinct cooling triggered by enhanced near-inertial currents is shown to be associated with the process of wind-current resonance. Both processes of Kuroshio intrusion and enhanced near-inertial currents are dominated by wind forcing rather than upper oceanic conditions. Based on the recent findings on the possible dynamic linkage between sea surface temperature near northeast Taiwan and local weather systems, the results elucidated in this study lay the foundation for further improvement in the regional weather prediction surrounding northeast Taiwan.

    There is renewed interest in studying the active and complex northeastern Caribbean plate boundary to better understand subduction zone processes and for earthquake and tsunami hazard assessments [e.g., ten Brink and Lin, 2004; ten Brink et al., 2004; Grindlay et al., 2005]. To study the active tectonics of this plate boundary, the GEOPRICO-DO (Geological, Puerto Rico-Dominican) marine geophysical cruise, carried out between 28 March and 17 April 2005 (Figure 1), studied the active tectonics of this plate boundary.Initial findings from the cruise have revealed a large underwater landslide, and active faults on the seafloor (Figures 2a and 2c). These findings indicate that the islands within this region face a high risk from tsunami hazards, and that local governments should be alerted in order to develop and coordinate possible mitigation strategies.

    Six multichannel seismic-reflection profiles taken across the Atlantic continental margin off the northeastern United States show an excess of 14 km of presumed Mesozoic and younger sedimentary rocks in the Baltimore Canyon trough and 8 km in the Georges Bank basin. Beneath the continental rise, the sedimentary prism thickness exceeds 7 km south of New Jersey and Maryland, and it is 4.5 km thick south of Georges Bank Stratigraphically, the continental slope--outer edge of the continental shelf is a transition zone of high-velocity sedimentary rock, probably carbonate, that covers deeply subsidized basement. The spatial separation of magnetic and gravity anomalies on line 2 (New Jersey) suggests that in the Baltimore Canyon region the magnetic-slope anomaly is due to edge effects and that the previously reported free-air and isostatic gravity anomalies over the outer shelf may be due in part to a lateral increase in sediment density (velocity) near the shelf edge. The East Coast magnetic anomaly and the free-air gravity high both coincide over the outer shelf edge on line 1 (Georges Bank) but are offset by 20 km from the ridge on the reflection profile

    Full Text Available Abstract Palaeonvironment of the Dalichai Formation, northeastern Semnan, is envisaged based on 69 samples studied palynologically. Diverse and well-preserved palynofloras, viz., miospores, dinoflagellate cysts, foraminiferal test linings, acritarchs, wood debris (plant tissue and Amorphous Organic Matters (AOM occur in the material examined. The presence of relatively abundant proximate dinoflagellates and ±laevigate acritarchs in the lower part of the section studied implies sedimentation in a turbulent shallow environment. However, occurrence in the upper part of the section of abundant chorate dinoflagellates as well as notable proportion of blade-shaped to equal dimensional opaque palynomacerals seem to signify marine incursion and accumulation in an open marine setting. In most of the samples examined, prevalence of transparent AOM denotes a low oxygenated environment and slow rate of accumulation. Moreover, incidence of three palynofacies types (II, IV, VI in the pertinent material also corroborates a shallow low oxygenated environment with low sedimentation rate which gradually deepened upward in the section.

  9. Uranium concentrations in groundwater, northeastern Washington

    2018-04-18

    A study of uranium in groundwater in northeastern Washington was conducted to make a preliminary assessment of naturally occurring uranium in groundwater relying on existing information and limited reconnaissance sampling. Naturally occurring uranium is associated with granitic and metasedimentary rocks, as well as younger sedimentary deposits, that occur in this region. The occurrence and distribution of uranium in groundwater is poorly understood. U.S. Environmental Protection Agency (EPA) regulates uranium in Group A community water systems at a maximum contaminant level (MCL) of 30 μg/L in order to reduce uranium exposure, protect from toxic kidney effects of uranium, and reduce the risk of cancer. However, most existing private wells in the study area, generally for single family use, have not been sampled for uranium. This document presents available uranium concentration data from throughout a multi-county region, identifies data gaps, and suggests further study aimed at understanding the occurrence of uranium in groundwater.The study encompasses about 13,000 square miles (mi2) in the northeastern part of Washington with a 2010 population of about 563,000. Other than the City of Spokane, most of the study area is rural with small towns interspersed throughout the region. The study area also includes three Indian Reservations with small towns and scattered population. The area has a history of uranium exploration and mining, with two inactive uranium mines on the Spokane Indian Reservation and one smaller inactive mine on the outskirts of Spokane. Historical (1977–2016) uranium in groundwater concentration data were used to describe and illustrate the general occurrence and distribution of uranium in groundwater, as well as to identify data deficiencies. Uranium concentrations were detected at greater than 1 microgram per liter (μg/L) in 60 percent of the 2,382 historical samples (from wells and springs). Uranium concentrations ranged from less than 1 to

    Full Text Available INTRODUCTION: This communication describes a retrospective study of the epidemiology of snakebite cases that were recorded from 2007 to 2012 in the State of Piauí, northeastern Brazil. METHODS: Data were collected from the Injury Notification Information System database of the State of Piauí's Health Department. RESULTS: A total of 1,528 cases were identified. The cases occurred most frequently in rural areas between January and July. Victims were predominantly male farmers, and were typically 30-39 years old. Most victims were bitten on the foot, and received medical assistance within 1-3h after being bitten. CONCLUSIONS: The epidemiological profile of snakebites in the State of Piauí is similar to that in all of Brazil.

    2013-11-01

    Full Text Available Human cases of West Nile virus (WNV disease have been reported in Italy since 2008. So far, most cases have been identified in north-eastern Italy, where, in 2012, the largest outbreak of WNV infection ever recorded in Italy occurred. Most cases of the 2012 outbreak were identified in the Veneto region, where a special surveillance plan for West Nile fever was in place. In this outbreak, 25 cases of West Nile neuroinvasive disease and 17 cases of fever were confirmed. In addition, 14 WNV RNA-positive blood donors were identified by screening of blood and organ donations and two cases of asymptomatic infection were diagnosed by active surveillance of subjects at risk of WNV exposure. Two cases of death due to WNND were reported. Molecular testing demonstrated the presence of WNV lineage 1 in all WNV RNA-positive patients and, in 15 cases, infection by the novel Livenza strain was ascertained. Surveillance in other Italian regions notified one case of neuroinvasive disease in the south of Italy and two cases in Sardinia. Integrated surveillance for WNV infection remains a public health priority in Italy and vector control activities have been strengthened in areas of WNV circulation.

    Six multichannel seismic-reflection profiles taken across the Atlantic continental margin Previous HitoffTop the northeastern United States show an excess of 14 km of presumed Mesozoic and younger sedimentary rocks in the Baltimore Canyon trough and 8 km in the Georges Bank basin. Beneath the continental rise, the sedimentary prism thickness exceeds 7 km south of New Jersey and Maryland, and it is 4.5 km thick south of Georges Bank. Stratigraphically, the continental slope--outer edge of the continental shelf is a transition zone of high-velocity sedimentary rock, probably carbonate, that covers deeply subsided basement. Acoustically, the sedimentary sequence beneath the shelf is divided into three units which are correlated speculatively with the Cenozoic, the Cretaceous, and the Jurassic-Triassic sections. These units thicken offshore, and some have increased seismic velocities farther offshore. The uppermost unit thickens from a fraction of a kilometer to slightly more than a kilometer in a seaward direction, and velocity values range from 1.7 to 2.2 km/sec. The middle unit thickens from a fraction of a kilometer to as much as 5 km (northern Baltimore Canyon trough), and seismic velocity ranges from 2.2 to 5.4 km/sec. The lowest unit thickens to a maximum of 9 km (northern Baltimore Canyon), and velocities span the 3.9 to 5.9-km/sec interval. The spatial separation of magnetic and gravity anomalies on line 2 (New Jersey) suggests that in the Baltimore Canyon region the magnetic-slope anomaly is due to edge effects and that the previously reported free-air and isostatic gravity anomalies over the outer shelf may be due in part to a lateral increase in sediment density (velocity) near the shelf edge. The East Coast magnetic anomaly and the free-air gravity high both coincide over the outer shelf edge on line 1 (Georges Bank) but are offset by 20 km from the ridge on the reflection profile.

    Tsering Bum ཚེ་རིང་འབུམ།

    Full Text Available Tsering Bum (b. 1985 describes his early life in Amdo in terms of dreams, herding, punishment from a lama, schooling experiences, attending a Kalachakra teaching, a lhatzi gathering, irrigation, his grandfather, archery, and other important moments and influences. Another incredible production from Kevin Stuart's Tibetan English students! Tsering Bum gives us a series of intricately woven vignettes of his childhood and adolescence in a small Tibetan village in Qinghai Province. A Northeastern Tibetan Childhood takes readers into the social and material culture of Tsering's family and fellow villagers. We begin with a home scene on the heated brick hyitsi 'bed', where the family sleeps, meals are taken, and guests are entertained. Through Tsering's writing we taste the noodles his mother makes by hand, know the life of the herders, meet ritualists who communicate with the mountain deity, visit a Kalachakra for blessings, experience an archery contest that ends in singing and drink, swim naked in cold mountain rivers, celebrate Losar, or Tibetan new year festival, visit a nomad festival, enter the transformative world of a county primary school, and hear the accounts of three deaths. The stories take us through a landscape of mountains, rivers, and grasslands to new worlds that for the narrator end with a kindled sense of global vision and self-worth. Mark Bender, Ohio State University I highly recommend this exciting new work. Tsering Bum's account of his life is a quick and pleasant read, full of insights into many aspects of contemporary Tibetan culture. From village rituals associated with death and archery contests to the challenges of modern schooling in rural areas, Tsering Bum leads us quickly through a narrative that links past and present to hopes for the future. Tibetan Buddhism and mountain pilgrimage play a limited but significant role in the story. As a historian, I was most interested in the chapter 'Grandpa' that recounts the

  11. Cenozoic mountain building on the northeastern Tibetan Plateau

    Lease, Richard O.

    2014-01-01

    Northeastern Tibetan Plateau growth illuminates the kinematics, geodynamics, and climatic consequences of large-scale orogenesis, yet only recently have data become available to outline the spatiotemporal pattern and rates of this growth. I review the tectonic history of range growth across the plateau margin north of the Kunlun fault (35°–40°N) and east of the Qaidam basin (98°–107°E), synthesizing records from fault-bounded mountain ranges and adjacent sedimentary basins. Deformation began in Eocene time shortly after India-Asia collision, but the northeastern orogen boundary has largely remained stationary since this time. Widespread middle Miocene–Holocene range growth is portrayed by accelerated deformation, uplift, erosion, and deposition across northeastern Tibet. The extent of deformation, however, only expanded ~150 km outward to the north and east and ~150 km laterally to the west. A middle Miocene reorganization of deformation characterized by shortening at various orientations heralds the onset of the modern kinematic regime where shortening is coupled to strike slip. This regime is responsible for the majority of Cenozoic crustal shortening and thickening and the development of the northeastern Tibetan Plateau.

    The principal area of tropical cyclogenesis in the tropical eastern Pacific Ocean is offshore in the Gulf of Tehuantepec, between 8 and 15 degrees Celsius N, and most of these cyclones move towards the west and northwest during their initial phase. Historical analysis of tropical cyclone data in the Northeastern (NE) Pacific over the last 38 years (from 1966 to 2004) shows a mean of 16.3 tropical cyclones per year, consisting of 8.8 hurricanes 198 and 7.4 tropical storms. The analysis shows great geographical variability of cyclone tracks, and that there were a considerable number of hurricane strikes along the Mexican coast. About 50% of the tropical cyclones formed turned north to northeast. It was rare that any passed further north than 30 degrees Celsius N in latitude because of the cold California Current. Hurricane tracks that affected the NE Pacific may be separated into 5 groups. We compared the historical record of the sea surface temperature (SST), related with the El Nino events with a data set of tropical cyclones, including frequency, intensity, trajectory, and duration. Although the statistical dependence between the frequencies of tropical cyclones of the most abundant categories, 1 and 2, over this region and SST data was not convincing, the percentage of high intensity hurricanes and hurricanes with a long life-time (greater than 12 days) was more during El Nino years than in non-El Nino years.

    Human exploitation of pinnipeds has considerable antiquity but shows increasing impacts on population numbers in the Holocene. Pinnipeds are a rich source of fat as well as protein. A few well-documented cases of regional extirpation of seals and sea lions by non-industrial peoples exist. The northeastern Pacific region, from southern California to Alaska, has yielded archaeological evidence for distributions and abundances of eared seals that differs markedly from historically documented biogeography. This is especially true of the northern fur seal (Callorhinus ursinus), among the most common pinnipeds in many archaeological sites from the Santa Barbara Channel area through to Kodiak Islands. This chapter reviews contemporary eared seal biogeography, evidence for the earlier timing and extent, of occurrence of northern fur seals along the northeastern Pacific coast, zooarchaeological and isotopic evidence for their foraging and probable maintenance of rookeries in lower latitudes, and for their disappearance from the southernmost part of their ancient distribution well before European contact. It also reviews ongoing debates over the behavioral ecology of ancient fur seals and over humans role in contributing to their disappearance.

    To describe the clinical, endoscopic, and serologic features of an outbreak of besnoitiosis in 2 donkey operations in northeastern Pennsylvania and to report the outcome of attempted treatment of 1 naturally infected individual. Observational study. 29 donkeys (Equus asinus) in northeastern Pennsylvania. Donkeys were examined for lesions suggestive of besnoitiosis in an outbreak investigation. Information was collected regarding the history and signalment of animals on each premises. Rhinolaryngoscopy was performed to identify nasopharyngeal and laryngeal lesions. Serum samples were collected for immunofluorescent antibody testing and immunoblotting for Besnoitia spp. Skin biopsy samples were obtained from 8 animals with lesions suggestive of besnoitiosis for histologic examination. Quantitative real-time PCR assay for Besnoitia spp was performed on tissue samples from 5 animals. Besnoitiosis was confirmed in 6 of the 8 suspected cases. The most common lesion site was the nares, followed by the skin and sclera. Donkeys with clinical signs of disease had higher serum antibody titers and tested positive for a greater number of immunoblot bands than did donkeys without clinical signs of disease. All animals evaluated by PCR assay tested positive. Putative risk factors for disease included age and sex. Ponazuril was not effective at treating besnoitiosis in a naturally infected donkey. Knowledge of clinical and serologic features of besnoitiosis in donkeys will assist clinicians in the diagnosis and prevention of this disease in donkey populations. Besnoitiosis may be an emerging disease of donkeys in the United States.

    Full Text Available The semi-arid region of Brazil represents approximately 57% of the northeastern territory. The main economic activity in this region is agriculture and livestock, in most cases, using traditional technologies. However, there is little published information currently available on cattle-raising in this part of Brazil. The objective of this study was to estimate genetic parameters and trends for productive and reproductive traits of Nellore cattle raised in semi-arid region of northeastern Brazil. Data were collected on weight-adjusted at 205 (W205, 365 (W365 and 550 (W550 days of life, age at first calving (AFC, calving interval (CI and scrotal circumference (SC at 550 days of life of cattle born between 1965 and 2011.

    Type 1 diabetes (T1D) is an organ-specific, T-cell-mediated disease resulting from the selective destruction of pancreatic β cells. The signal transducer and activator of transcription 4 (STAT4) gene is one of the most interesting genes for the pathogenesis of autoimmune diseases, including T1D. In this study, a case-control study was conducted in a Han population in northeastern China comparing the genotypes of T1D patients to healthy controls for the presence of two single-nucleotide polymorphisms (SNPs) in the STAT4 gene. The study population comprised of 410 T1D patients and 407 healthy individuals. Two SNPs (rs7574865 and rs3024866) of STAT4 were genotyped with Multiplex SNaPShot method. Data were analyzed with spss 13.0 to determine if a statistical association existed between these genotypes and T1D. One of the two SNPs (rs7574865) was strongly associated with T1D in Northeastern Chinese population compared to healthy controls (P < 0.05), whereas the other tested SNP (rs3024866) demonstrated no significant relationship. In conclusion, the STAT4 gene may play an important role in facilitating susceptibility to T1D in this Han Chinese population. © 2013 John Wiley & Sons A/S.

    Christiane Sampaio de Souza

    Full Text Available Abstract Data collected on large-scale surveys around the seamounts and islands off northeastern Brazil provide information on the hyperiid amphipod populations. Thirty-six species were identified. Most of the species belong to the Infraorder Physocephalata, representing 21 genera and 13 families. Thirteen species (Vibilia australis, L. latissimus, L. macrophthalmus, L. schizogeneios, Phronima atlantica, Phrosina semilunata, Primno brevidens, Eupronoe minuta, Oxycephalus clause, Rhabdosoma whitei, Amphithyrus bispinosus, Leptocotis tenuirostris and Tetrathyrus forcipatus have not previously been recorded in this region. The spatial distribution of the hyperiid amphipods was very patchy. Each area of these amounts and islands off northeastern Brazil has different oceanographic features and can be characterised by a clearly defined group of most abundant species.

    Samples of moss carpets growing in forest vegetation have been used to map radioactive fallout in northeastern Italy. The main factors affecting data variability are the inclination of the carpets, water absorbing power, and their thickness. The best suited bioindicator proved to be Ctenidium molluscum. The results indicate that these carpets were able to intercept most of the radiocesium deposited after the Chernobyl accident, and that the removal half-time in the survey area is of circa 46 months

  16. Issues of Caribou Management in Northeastern British Columbia

    Directory of Open Access Journals (Sweden)

    Scott Harrison

    1996-01-01

    Full Text Available Woodland caribou inhabit most of Northeastern British Columbia. They live across a variety of climatic and geographic gradients and in areas with as many as seven other ungulate species and seven predatory species. This apparent variability in habitat use may suggest that caribou in the Northeast are wide ranging and ecologically plastic. Conversely, caribou in Northeastern B.C. may live in discrete groups that have adapted to local conditions. There are few published data of woodland caribou in Northeastern B.C. Information is lacking on the number of caribou, their seasonal movements, their habitat requirements, and their interactions with other species. Logging, seismic activity, pipeline construction, oil and natural gas drilling, hydro-electric dams, and prescribed burning have all impacted habitat in previously undeveloped areas. The manner and rate at which these activities are changing habitats far exceeds our growth in knowledge of caribou ecology. Given this combination of few data and rapid habitat alteration, resource managers cannot know the impact of these habitat changes. We believe that this jeopardises the conservation of viable caribou populations.

    An earthquake catalogue of instrumental data for northeastern Italy since 1900 is presented. The different types of magnitude, which are the main parameters of the present study, have been evaluated so as to be as homogeneous as possible. Comparisons of the different magnitude values show linear dependence, at least in the medium magnitude range represented by the available data set. Correlations between the magnitude most significant for this region and chosen macroseismic data indicate a methodology for assessing the macroseismic magnitude of historical earthquakes which seems to be stable.

    Full Text Available Background: Thrombophilia is a main predisposition to thrombosis due to a procoagulant state. Several point mutations play key roles in blood-clotting disorders, which are grouped under the term thrombophilia. These thrombophilic mutations are methylenetetrahydrofolate reductase (MTHFR, C677T, and A1298C, factor V Leiden (G1691A, prothrombin gene mutation (factor II, G20210A, and plasminogen activator inhibitor (PAI. In the present study, we assessed the prevalence of the above thrombophilia markers in patients with recurrent pregnancy loss or first and second trimester abortions, infertility, and failed in vitro fertilization (IVF. Methods: This study was conducted among 457 cases those were referred to detect the inherited genetic markers for thrombophilia. Markers for MTHFR, Factor II, and Factor V were assessed by polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP, and PAI was assessed by Amplification Refractory Mutation System (ARMS-PCR. Results: Two hundred sixty cases (56.89% were diagnosed as having at least one thrombophilia marker, whereas 197 cases (43.11% had no thrombophilia markers and were normal. Conclusion: According to the current study, the pattern of abnormal genetic markers for thrombophilia in northeastern Iran demonstrates the importance of genetic evaluations in patients who show clinical abnormalities with recurrent spontaneous abortion (RSA or other serious obstetric complications.

    1998-01-01

    Full Text Available Childhood malnutrition has been a major, long-standing health concern in northeastern Brazil. In response, during 1992_1994, the state government of Ceará, with financial support from the World Bank, established 34 new nutrition centers. During 1996 an evaluation of the centers was conducted to determine their effectiveness in treating children with malnutrition and to identify weaknesses in the system and possible solutions. Also evaluated were the adequacy of resources, admission and discharge criteria, staff training, and community satisfaction. Effectiveness was found to be low. Treatment procedures did not conform with World Health Organization recommendations. Rates of weight gain were inadequate, and the mean duration of rehabilitation-8.7 months-was too long. Case fatality in two centers was unacceptably high, 40% and more. Entry and exit criteria for rehabilitation were ill defined, resulting in some nonmalnourished children being enrolled. Few staff were adequately trained; knowledge was weak, especially about case management; and mothers were not effectively instructed. Recommendations include setting objectives for the centers, improving referral systems, standardizing entry criteria, improving case management, and establishing performance indicators.

    Marine plastic pollution is an increasing, and global, environmental issue. Numerous marine species are affected by plastic debris through entanglement, nest incorporation, and ingestion, which can lead to lethal and sub-lethal impacts. However, in the northeastern Atlantic Ocean, an area of international importance for seabirds, there has been little effort to date to assess information from studies of wildlife and plastic to better understand the spatiotemporal variation of how marine plastic affects different seabird species. To improve our understanding of seabirds and marine plastic in this region, we completed a synthesis of the published and grey literature to obtain information on all known documented cases of plastic ingestion and nest incorporation by this group. We found that of 69 seabird species that commonly occur in the northeastern Atlantic, 25 had evidence of ingesting plastic. However, data on plastic ingestion was available for only 49% of all species, with 74% of investigated species recorded ingesting plastic. We found only three published studies on nest incorporation, for the Northern Gannet (Morus bassanus) and Black-legged Kittiwake (Rissa tridactyla). For many species, sample sizes were small or not reported, and only 39% of studies were from the 21st century, whilst information from multiple countries and years was only available for 11 species. This indicates that we actually know very little about the current prevalence of plastic ingestion and nest incorporation for many species, several of them globally threatened. Furthermore, in the majority of studies, the metrics reported were inadequate to carry out robust comparisons among locations and species or perform meta-analyses. We recommend multi-jurisdictional collaboration to obtain a more comprehensive and current understanding of how marine plastic is affecting seabirds in the northeastern Atlantic Ocean.

    The Centro di Ricerche Sismologiche (CRS, Seismological Research Center) of the Istituto Nazionale di Oceanografia e di Geofisica Sperimentale (OGS, Italian National Institute for Oceanography and Experimental Geophysics) in Udine (Italy) after the strong earthquake of magnitude M=6.4 occurred in 1976 in the Italian Friuli-Venezia Giulia region, started to operate the Northeastern Italy Seismic Network: it currently consists of 17 very sensitive broad band and 18 simpler short period seismic stations, all telemetered to and acquired in real time at the OGS-CRS data center in Udine. Real time data exchange agreements in place with other Italian, Slovenian, Austrian and Swiss seismological institutes lead to a total number of about 100 seismic stations acquired in real time, which makes the OGS the reference institute for seismic monitoring of Northeastern Italy. The southwestern edge of the OGS seismic network stands on the Po alluvial basin: earthquake localization and characterization in this area is affected by the presence of soft alluvial deposits. OGS ha already experience in running a local seismic network in high noise conditions making use of borehole installations in the case of the micro-seismicity monitoring of a local gas storage site for a private company. Following the ML=5.9 earthquake that struck the Emilia region around Ferrara in Northern Italy on May 20, 2012 at 02:03:53 UTC, a cooperation of Istituto Nazionale di Geofisica e Vulcanologia, OGS, the Comune di Ferrara and the University of Ferrara lead to the reinstallation of a previously existing very broad band (VBB) borehole seismic station in Ferrara. The aim of the OGS intervention was on one hand to extend its real time seismic monitoring capabilities toward South-West, including Ferrara and its surroundings, and on the other hand to evaluate the seismic response at the site. We will describe improvements in running the Northeastern Italy Seismic Network, including details of the Ferrara VBB

    Mycoplasma infections can cause significant morbidity and mortality in captive and wild chelonians. As part of a health assessment of endangered bog turtles (Glyptemys muhlenbergii) in the northeastern US, choanal and cloacal swabs from these and other sympatric species, including spotted turtles (Clemmys guttata), eastern box turtles (Terrapene carolina carolina), wood turtles (Glyptemys insculpta), and common snapping turtles (Chelydra serpentina) from 10 sampling sites in the states (US) of Delaware, New Jersey, and Pennsylvania, were tested by PCR for Mycoplasma. Of 108 turtles tested, 63 (58.3%) were PCR positive for Mycoplasma including 58 of 83 bog turtles (70%), three of three (100%) eastern box turtles, and two of 11 (18%) spotted turtles; all snapping turtles (n = 7) and wood turtles (n = 4) were negative. Sequence analysis of portions of the 16S-23S intergenic spacer region and the 16S ribosomal RNA gene revealed a single, unclassified species of Mycoplasma that has been previously reported in eastern box turtles, ornate box turtles (Terrapene ornata ornata), western pond turtles (Emys marmorata), and red-eared sliders (Trachemys scripta elegans). We document a high incidence of Mycoplasma, in the absence of clinical disease, in wild emydid turtles. These findings, along with wide distribution of the identified Mycoplasma sp. across a broad geographic region, suggest this bacterium is likely a commensal inhabitant of bog turtles, and possibly other species of emydid turtles, in the northeastern US.

    In the present study, the K-40, U-238, Ra-226, Pb-210, Ra-228 and Th-228 activity concentrations were measured in 64 samples of wastes generated from shale gas exploration in North-Eastern Poland. The measured samples consist of drill cuttings, solid phase of waste drilling muds, fracking fluids, return fracking fluids and waste proppants. The measured activity concentrations in solid samples vary in a wide range from 116 to around 1100 Bq/kg for K-40, from 14 to 393 Bq/kg for U-238, from 15 to 415 Bq/kg for Ra-226, from 12 to 391 Bq/kg for Pb-210, from a few Bq/kg to 516 Bq/kg for Ra-228 and from a few Bq/kg to 515 Bq/kg for Th-228. Excluding the waste proppants, the measured activity concentrations in solid samples oscillate around their worldwide average values in soil. In the case of the waste proppants, the activity concentrations of radionuclides from uranium and thorium decay series are significantly elevated and equal to several hundreds of Bq/kg but it is connected with the mineralogical composition of proppants. The significant enhancement of Ra-226 and Ra-228 activity concentrations after fracking process was observed in the case of return fracking fluids, but the radium isotopes content in these fluids is comparable with that in waste waters from copper and coal mines in Poland.

    Over 40,000 residents (less than or equal to 40 years of age) in a city (Sendai; the city group), a town (Shiroishi; the town group) and two villages (Wakuya and Tajiri; the village group) in Miyagi prefecture in north-eastern Japan responded in a questionnaire survey on their attitude towards mass health examinations (i.e., whether they underwent in the previous year and if so where) on 4 items of blood pressure measurement, chest x-ray examination and screening tests for stomach and cervical cancer. The coverage rates were about 70% on an average both for blood pressure measurement and for chest x-ray examination, whereas the rates for cancer screening were between 30-40%. As for the opportunity of the former two examinations, the workplace mass examination played a large role in the case of the city and town groups (especially among men but not women) in addition to visit to clinics, in contrast to the case of the village group in which people depended much on regional mass examination service. The trend was essentially reproducible in stomach cancer screening although the over-all coverage rate was low, whereas women in the three groups almost exclusively utilized clinics for cervical cancer screening with one exception that the mobile unit service appeared to be equally accepted in the village group.

    An outbreak characterized by vomiting and rapid progression to unconsciousness and death was reported in Sylhet Distrct in northeastern Bangladesh following destructive monsoon floods in November 2007. We identified cases presenting to local hospitals and described their clinical signs and symptoms. We interviewed patients and their families to collect illness histories and generate hypotheses about exposures associated with disease. An epidemiological study was conducted in two outbreak villages to investigate risk factors for developing illness. 76 patients were identified from 9 villages; 25% (19/76) died. Common presenting symptoms included vomiting, elevated liver enzymes, and altered mental status. In-depth interviews with 33 cases revealed that 31 (94%) had consumed ghagra shak, an uncultivated plant, in the hours before illness onset. Ghagra shak was consumed as a main meal by villagers due to inaccessibility of other foods following destructive monsoon flooding and rises in global food prices. Persons who ate this plant were 34.2 times more likely (95% CI 10.2 to 115.8, p-valuestrumarium, or common cocklebur. The consumption of Xanthium strumarium seedlings in large quantities, due to inaccessibility of other foods, caused this outbreak. The toxic chemical in the plant, carboxyatratyloside, has been previously described and eating X. strumarium seeds and seedlings has been associated with fatalities in humans and livestock. Unless people are able to meet their nutritional requirements with safe foods, they will continue to be at risk for poor health outcomes beyond undernutrition.

    Stabilized eolian deposits, mostly parabolic dunes and sand sheets, cover much of the landscape of northeastern Colorado and adjacent parts of southwestern Nebraska in four geographically distinct dune fields. Stratigraphic and soil-geomorphic relations and accelerator radiocarbon dating indicate that at least three episodes of eolian sand movement occurred between 27 ka and 11 ka, possibly between 11 ka and 4 ka, and within the past 1.5 ka. Thus, eolian sand deposition took place under both glacial and interglacial climatic conditions. In the youngest episodes of eolian sand movement, Holocene parabolic dunes partially buried Pleistocene sand sheet deposits. Late Holocene sands in the Fort Morgan and Wray dune fields, to the south of the South Platte River, have trace element ratios that are indistinguishable from modern South Platte River sands, but different from Ogallala Formation bedrock, which has previously been cited as the main source of dune sand on the Great Plains. Sands in the Greeley dune field, to the north of the South Platte River, have trace element concentrations that indicate a probable Laramie Formation source. Measurements of parabolic dunes indicate paleowinds from the northwest in all dune fields, in good agreement with resultant drift directions calculated for nearby weather stations. Thus, paleowinds were probably not significantly different from present-day winds, and are consistent with a South Platte River source for the Fort Morgan and Wray dune fields, and a Laramie Formation source for the Greeley dune field. Sand accumulated downwind of the South Platte River to form the Fort Morgan dune field. In addition, sand was also transported farther downwind over the upland formed by the calcrete caprock of the Ogallala Formation, and deposited in die lee of the upland on the southeast side. Because of high wind energy, the upland itself served as a zone of sand transport, but little or no sand accumulation took place on this surface. These

  19. Cemented Horizons and Hardpans in the Coastal Tablelands of Northeastern Brazil

    Directory of Open Access Journals (Sweden)

    Full Text Available ABSTRACT Horizons with varying degrees of cementation are a common feature of the soils from the coastal tablelands of Northeastern Brazil. In most cases, these horizons are represented by the following subsurface horizons: fragipan, duripan, ortstein, and placic. The aims of this study were to analyze differences regarding the development and the degree of expression of cementation in soils from the coastal tablelands of Northeastern Brazil: Planossolo Háplico (p-SX, Espodossolo Humilúvico (p-EK, Espodossolo Ferrihumilúvico (p-ESK, and Argissolo Acinzentado (p-PAC pedons. The pedons studied displayed features related to drainage impediments. The cemented horizons from p-SX and p-EK had the same designation (Btgm, displaying a duric character that coincided with gleization features and are under podzolized horizons. In the p-ESK, the podzolization process is of such magnitude that it leads to the cementation of its own spodic horizons, which were both of the ortstein type (Bhsx and Bsm. In the p-PAC cementation is observed in two placic horizons and in the Btx/Bt horizon, as well as in the upper parts of the Bt/Btx horizon. Analysis of the micrographies from the cemented horizons showed predominance of a low porosity matrix. Such porosity is relatively greater in the horizons of “x” subscript than in the horizons with duric character. The Fe segregation lines were notable in the cemented horizons from p-EK and p-PAC, which corroborates the presence of placic horizons in such pedons. The preponderance of kaolinite in the clay fraction was widely verified in all the cemented horizons analyzed. Water immersion tests were the criteria adopted to define the duric character of the Btgm horizons from p-SX and p-EK, and in the Bsm horizon from the p-ESK. These tests were also used to confirm field morphology. In most cases, the maximum values of Fe, Al, and Si, determined by different extractions, occurred in positions overlaying the cemented

    The aim of this study was to detect DNA and antibodies anti-Leishmania spp., Neospora caninum and Toxoplasma gondii in captive and free-range crab-eating fox (Cerdocyon thous) from northeastern Brazil. Twenty-five crab-eating foxes from different states of northeastern Brazil were sampled by this study. Blood samples were collected by cephalic or jugular vein punctures. The whole blood was submitted to PCR, and the sera samples to the serological analysis as follows: MAT for T. gondii, NAT for N. caninum, and ELISA for L. chagasi. The frequence of antibodies anti-T. gondii was 50% and 29.41% for free-range and captive wild canids, respectively. The frequence of antibodies anti-N. caninum observed by this study was 62.50% and 23.52% for free-range and captive wild canids, respectively. The frequence of antibodies anti-L. chagasi was 4.0% for captive wild canids. Co-infections cases were identified as follows: one captive wild canid seropositive for T. gondii and L. chagasi and two free-range animals seropositive for T. gondii and N. caninum. All PCR assays performed were negative for the pathogens analyzed. This study describes the presence of antibodies anti-T. gondii, N. caninum e L. chagasi in wild canids from northeastern Brazil and highlights the necessity of further studies on infectious diseases in free-range and captive wild canids.

    Testing of 1701 water wells in northeastern Pennsylvania shows that methane is ubiquitous in groundwater, with higher concentrations observed in valleys vs. upland areas and in association with calcium-sodium-bicarbonate, sodium-bicarbonate, and sodium-chloride rich waters—indicating that, on a regional scale, methane concentrations are best correlated to topographic and hydrogeologic features, rather than shale-gas extraction. In addition, our assessment of isotopic and molecular analyses of hydrocarbon gases in the Dimock Township suggest that gases present in local water wells are most consistent with Middle and Upper Devonian gases sampled in the annular spaces of local gas wells, as opposed to Marcellus Production gas. Combined, these findings suggest that the methane concentrations in Susquehanna County water wells can be explained without the migration of Marcellus shale gas through fractures, an observation that has important implications for understanding the nature of risks associated with shale-gas extraction.

    With reference to the distribution of radium-226 in the western equatorial and north-eastern deep Atlantic Ocean it was possible to establish structures in the correlations of radium-226 to its chemical homologue Ba and dissolved SiO 2 . An 11-box model of the deep Atlantic Ocean was used to obtain information on the size of the radium-226 and Ba sources. The soil source derives mainly from the dissolution of barite. For the first time, an evaluation of the radium-226 flow resulting from the dissolution of particulate matter is presented. The box model and the radium-226 concentrations measured put down the value as 23-46·10 -21 mol/m 2 s. (DG) [de

    The concentrations of sulfur dioxide (SO 2 ), ammonia (NH 3 ) and particulate matter were measured for a 6-month period and the concentration of gas phase nitric acid (HNO 3 ) was measured for a 1-month period in the North-eastern Mediterranean atmosphere (Kuecuek Calticak, Antalya) using a 'filter pack' system that was developed and optimised in our laboratory. Among all the gas phase pollutants, HNO 3 had the lowest concentration (0.42 μg m -3 ) followed by ammonia. Most of the measured parameters showed variation in time depending on strengths of source regions and meteorological conditions. Nitric acid is found mostly in particulate form, but gas to particulate partitioning of SO 2 shows seasonal variation. Wind trajectory analyses indicate that the major contribution to the observed concentrations come mostly from Eastern Europe and Blacksea regions as well as the southern sector

    The northeastern North Carolina coastal system, from False Cape, Virginia, to Cape Lookout, North Carolina, has been studied by a cooperative research program that mapped the Quaternary geologic framework of the estuaries, barrier islands, and inner continental shelf. This information provides a basis to understand the linkage between geologic framework, physical processes, and coastal evolution at time scales from storm events to millennia. The study area attracts significant tourism to its parks and beaches, contains a number of coastal communities, and supports a local fishing industry, all of which are impacted by coastal change. Knowledge derived from this research program can be used to mitigate hazards and facilitate effective management of this dynamic coastal system.

    Sagitta otolith shape was analysed in twenty sympatric rockfishes off the southern California coast (Northeastern Pacific). The variation in shape was quantified using canonical variate analysis based on fifth wavelet function decomposition of otolith contour. We selected wavelets because this representation allow the identifications of zones or single morphological points along the contour. The entire otoliths along with four subsections (anterior, ventral, posterodorsal, and anterodorsal) with morphological meaning were examined. Multivariate analyses (MANOVA) showed significant differences in the contours of whole otolith morphology and corresponding subsection among rockfishes. Four patterns were found: fusiform, oblong, and two types of elliptic. A redundancy analysis indicated that anterior and anterodorsal subsections contribute most to define the entire otolith shape. Complementarily, the eco-morphological study indicated that the depth distribution and strategies for capture prey were correlated to otolith shape, especially with the anterodorsal zone. © 2014 Wiley Periodicals, Inc.

Para uma caracterização dos recursos hídricos foram obtidos, no período de 1998 a 2000, dados de chuva, de vazão nos riachos do Chuchu e Capoeirão, e de qualidade da água, nos dois cursos d'água e nos três maiores reservatórios existentes no Parque. No estudo de demandas pelo uso da água, ênfase maior foi dada aos conflitos da atividade de irrigação em relação ao uso da água para abastecimento público e à preservação dos ecossistemas locais. Neste trabalho, conclui-se que em Brejo dos Cavalos a precipitação pluviométrica é superior a do seu entorno, devido a razões orográficas e à própria existência da floresta remanescente, mas o desmatamento progressivo tende a alterar as condições microclimáticas locais. Neste contexto, o cultivo do chuchu é o principal consumidor de água no Parque, gerando perda de vazão dos cursos d'água e menor aporte para os reservatórios, os quais já começaram a sofrer assoreamento, devido a processos erosivos gerados sobretudo pelos desmontes na exploração da argila. Tais constatações exigem ação imediata do poder público, principalmente a implantação de um Plano de Manejo para o Parque.Humid areas at high altitude are found in semi-arid region of Pernambuco and Paraíba in Northeastern Brazil. Although the vegetation in the surrounding area is the semi-arid 'caatinga', in these high altitude areas, natural vegetation is similar to that of the

    Full Text Available The aim of our research was to determine the share of physically compromised and physically talented children in northeastern Slovenia. The sample comprised 621 children aged nine to eleven years, among which there were 316 girls (M=10; SD=0.8 and 305 boys (M=10; SD=0.81. In order to assess their motor skills, seven different tests were used, mostly from Eurofit test battery, which covered explosive power, repetitive power balance, eye–hand coordination, speed of simple movements, whole body coordination, and endurance. The assessment was made for each physical fitness test separately. The cut-off points for determination of physically compromised and physically talented children were set at -1SD and +1SD, respectively. The results of all physical fitness tests showed that the share of physically compromised children exceeded ten percent for both genders. The largest number of boys and girls were physically compromised with regard to endurance and balance, respectively. On the other hand, boys proved to be most physically talented with regard to endurance, and girls with regard to explosive power. Gender differences were most obvious with regard to general endurance, as 21 per cent of the boys were physically compromised as opposed to 13 per cent of the girls. As for physical talent, we observed less gender-related differences. The results indicate increasing differences in physical fitness among children from northeastern Slovenia. The implementation of curricular and extracurricular sports activities should aim at reducing the number of physically compromised children. On the other hand, it would make sense to encourage physically talented children to get involved in organized forms of exercise.

    Full Text Available Improving the sustainability of traditional resource-based cities in China has been a core issue and policy-priority for Chinese government to establish long-term ecological civilization, particularly for northeastern China which is recognized as a typical agglomeration area of resources cities. In this study, we establish a three-layer index system consisting of a comprehensive layer, systemic layer, and variable layer, and including 22 indicators which are grouped into economic, social and environmental subsystems. After that, the TOPSIS (Technique for Order Preference by Similarity to Ideal Solution method was applied to measure and rank the sustainability of the selected 15 typical resource-based cities in northeast China, and then a GIS (Geographical Information System technique based on the software of SuperMap was applied to map the sustainability in terms of the spatial effects among these cities. The results reveal that a unilateral improvement of a subsystem did not mean an improvement or contribution to whole system. In detail, during the past 15 years from 2000 to 2015, the comprehensive sustainability of resource-based cities in Northeastern China shows a declining trend in the mass, and the sustainability of the economic subsystem shows increase; the sustainability of the social system remains stable, while the environmental subsystem shows decrease. These situations might result from policy interventions during the past 15 years, therefore, promoting the sustainability of resource-based cities needs a historical approach, which should focus on the coordinated development of its economic, social, and environmental subsystems.

    Tibetan Plateau, the so-called "Roof of the World", is a direct consequence of collision of the Indian plate with the Eurasian plate starting in the early Cenozoic time. The continent-continent collision is still going on. The northeastern margin of Tibetan Plateau is the front part of the Tibetan Plateau extends to mainland and favorable area for studying uplift and deformation of the Tibetan Plateau. In the past decades, a variety of geophysical methods were conducted to study geodynamics and geological tectonics of this region. We assembled satellite-derived free-air gravity anomalies with a resolution of one arc-minute from the Scripps Institution of Oceanography, and reduced them to obtain Complete Bouguer Gravity Anomalies. Then we gridded Complete Bouguer Gravity Anomalies on a regular grid, and subsequently processed them with the preferential continuation method to attenuate high-frequency noise and analyzed regional and residual anomalies. We also calculated tilt-angle derivative of Complete Bouguer Gravity Anomalies to derive clearer geological structures with more details. Then we calculated the depth distribution of the Moho discontinuity surface in this area by 3D density interface inversion. From the results of preliminary processing, we analyzed the main deep faults and geological tectonics in this region. We extracted seven important profiles' data of Complete Bouguer Gravity Anomalies in this area, and then did forward modeling and inversion on each profile with constraints of geological information and other geophysical data. In the future, we will perform 3D constrained inversion of Complete Bouguer Gravity Anomalies in this region for better understanding deep structure and tectonics of the northeastern margin of Tibetan Plateau.

  19. Effects of social change on wildlife consumption taboos in northeastern Madagascar

    Full Text Available In Madagascar, the constellation of taboos serves as a form of informal regulatory institution and is foundational to Malagasy culture, regardless of class, ethnic group affiliation, and educational background. Many researchers have credited rapid social change as a crucial mechanism for disturbing taboos. Others suggest that taboos are innately historical. However, very little empirical research has assessed the effects of social change on taboos or quantified the stability of taboo systems over time. Here, we use a case study of the ensemble of taboos in northeastern Madagascar, still a critical aspect of social life there, as a lens through which we investigate its degree of stability over time. Our aim was: (1 to describe the food taboos of local Malagasy living in northeastern Madagascar, and (2 to quantitatively assess the stability of these taboos to address certain claims regarding cultural erosion using an empirical, hypothesis-driven approach with rich ethnographic material to aid in interpretation. We investigated the temporal stability of taboos and local adherence to the moral framework, finding that approximately 3.0% of 4857 taboos were not adhered to at least once during the course of a 7-yr follow-up study. Additionally, we quantitatively explored the mediating effects of migration, modernization, and the spread of Western religion on number of taboos and level of adherence. We found that the presence of extra-local groups and migration did not decrease the number of taboos abided by locally, but did increase rates of nonadherence. Modernization accompanied by generational shifts tended to increase rather than erode the number of taboos, and younger individuals adhered to taboos to the same degree as older individuals. The effect of Western religion depended on the denomination, but generally reduced the number of taboos, although it did not affect adherence. The ways in which social change affects the stability of taboos are

    In the Borborema Province (Northeastern Brazil), the Brasiliano/Pan-African Cycle is expressed by two prominent and penecontemporaneous features: a regional network of transcurrent shear zones and associated large granitoid magmatism. The Rio Grande do Norte Domain (RGND) is an orogenic domain located in the northeastern part of the Borborema Province, and its tectonic evolution is largely related to the Brasiliano orogeny (ca. 600 Ma). This domain includes four major tectonic terranes, which are represented by two metavolcanosedimentary sequences Jaguaribe-Oeste Potiguar and Serido belts, and its gneiss-migmatite Paleoproterozoic basement the Rio Piranhas and Sao Jose de Campestre massifs (Brito Neves et al., 2000). The rocks have been metamorphosed up to the amphibolite facies. Its deformational fabrics are dominated by extensive Brasiliano ductile shear zones displaying predominantly dextral transcurrent kinematic regime. These structures control the emplacement of several Neoproterozoic granitoid intrusions which are made up mainly by porphyritic granitoid suites with subalkaline monzonitic affinity. These occur as isolated plutons of various sizes or as composite intrusions, associated with basic-tointermediate suites. In the latter case, magma mingling and mixing attest that these are contemporaneous igneous suites. Several features suggest coeval relationships with granitic magmas, possibly implying processes such as assimilation or magma mixing. Field evidence of magma mixing include (i) extensive capture of feldspar phenocrysts of the acid mushes by the basic magmas, (ii) common presence of globular to ellipsoidal basic enclaves in the granitic suites, (iii) stockwork-type features consisting of felsic material veining through a diorite host and (iv) syn-plutonic basic dykes intruded into the porphyritic granites (Jardim de S 1994). In this work, Rb-Sr and Sm-Nd isotopic compositions from six distinct basic-to-intermediate suites were investigated to

    The purpose of the present study was to determine the incidence of inflammatory bowel disease (IBD) and its subgroups in children in northeastern Slovenia (NE Slovenia) during the period 2002-2010, and to assess the phenotypic characteristics at the diagnosis and during the follow-up. A retrospective investigation was conducted on a cohort of newly diagnosed children and adolescents with IBD ages 0 to 18 years between 2002 and 2010 and residing in NE Slovenia. The phenotypic characteristics were determined at presentation and during follow-up. The location of Crohn disease (CD) and ulcerative colitis (UC) was assessed according to the Paris classification at diagnosis, and later in patients who had a follow-up period >2 years. The type of therapy at diagnosis and during follow-up, and the need for surgery were determined. The study covered approximately one-third of the total pediatric population (0-18 years). In total, 107 cases of IBD were diagnosed during the study period. The mean annual incidence (per 100,000) was 7.6 (95% confidence interval [CI] 6.3-9.2) for all IBD, 4.6 (95% CI 3.6-5.9) for CD, and 2.8 (95% CI 1.9-3.8) for UC. The incidences of total IBD, CD, and UC increased from 5.7 (3.8-8.2), 3.9 (2.3-6.1), and 1.8 (0.8-3.5) in the period 2002-2004, respectively, to 8.9 (6.3-12.2), 5.0 (3.1-7.6), and 3.4 (1.9-5.6) in the period 2008-2010, respectively. During the follow-up, the proportion of complicated CD disease behavior (stricturing/penetrating) had doubled. A total of 18.5% of patients with CD underwent bowel surgery. The incidence of childhood IBD in the northeastern part of the country is high and comparable with that reported from the developed western countries of Europe, and is probably still increasing. This increase may be the result of changes in the lifestyle, especially in dietary habits during the last 20 years.

  2. Moho Depth Variations in the Northeastern North China Craton Revealed by Receiver Function Imaging

    2016-12-01

    The North China Craton (NCC), one of the oldest cratons in the world, has attracted wide attention in Earth Science for decades because of the unusual Mesozoic destruction of its cratonic lithosphere. Understanding the deep processes and mechanism of this craton destruction demands detailed knowledge about the deep structure of the region. In this study, we used two-year teleseismic receiver function data from the North China Seismic Array consisting of 200 broadband stations deployed in the northeastern NCC to image the Moho undulation of the region. A 2-D wave equation-based poststack depth migration method was employed to construct the structural images along 19 profiles, and a pseudo 3D crustal velocity model of the region based on previous ambient noise tomography and receiver function study was adopted in the migration. We considered both the Ps and PpPs phases, but in some cases we also conducted PpSs+PsPs migration using different back azimuth ranges of the data, and calculated the travel times of all the considered phases to constrain the Moho depths. By combining the structure images along the 19 profiles, we got a high-resolution Moho depth map beneath the northeastern NCC. Our results broadly consist with the results of previous active source studies [http://www.craton.cn/data], and show a good correlation of the Moho depths with geological and tectonic features. Generally, the Moho depths are distinctly different on the opposite sides of the North-South Gravity Lineament. The Moho in the west are deeper than 40 km and shows a rapid uplift from 40 km to 30 km beneath the Taihang Mountain Range in the middle. To the east in the Bohai Bay Basin, the Moho further shallows to 30-26 km depth and undulates by 3 km, coinciding well with the depressions and uplifts inside the basin. The Moho depth beneath the Yin-Yan Mountains in the north gradually decreases from 42 km in the west to 25 km in the east, varying much smoother than that to the south.

    Many investigators consider children's drawings to be an important test in the evaluation of stress and anxiety, but few studies have examined the reliability and validity of indicators of emotional distress in children's projective drawings. In this report, we describe screening tests in children coming to the Friuli Venezia Giulia region in Northeastern Italy from non-European Union regions and suspected to have celiac disease, the problems involved in diagnosis of the disease, and the "drawn double nostalgia" of Romanian children for both Italian food and traditional Romanian foods. Of 3150 Western European cases, we found 712 with positive antibodies for IgA/IgG antitransglutaminase, 174 with a positive antiendomysium antibody confirmation test, and 20 with an IgA deficit. Of the children examined, 93% were children native to Western Europe, 4% were immigrants from Eastern Europe, and 1.6% originated from Africa. Among these, four Romanian children with celiac disease brought in their drawings, as requested in a hospital questionnaire. The prevalence of celiac disease is destined to increase among immigrants. Economic problems are common, and the twin nostalgia of immigrant children for foods and tastes that are "cozonac" (from the native country) and "panettone" (Italian cake flavor) represents a problem that will be difficult to resolve. Only some children's hospitals in Italy, ie, Burlo Garofolo and Gaslini, public and private foundations, or volunteer associations would be able to deal with this problem.

    Full Text Available The Douro river basin, in north-eastern Portugal, is a very complex region in terms of its geomorphological structure and morphodynamics. More specifically, the region – the Port Wine-growing region, a UNESCO heritage site – is a landslide-prone area resulting from several factors intrinsic to the bedrock and its detritic cover, combined with factors capable of triggering slope instability mechanisms, such as intense rainfall and human activities. Recently, due to intense rainfall and human activities, frequent rock and mud slides occurred, some of them catastrophic, killing people and damaging property. In the last decade (2000–2010, an accurate inventory of these catastrophic events was made, showing that these events occurred near local small towns, Peso da Régua (2001, Armamar (2003 and Carrazeda de Ansiães (2007. In this paper, we present a case study using field data and Geographic Information Systems (GIS tools to evaluate landslide hazard and risk assessment following multicriteria evaluation techniques.

  5. Recent Earthquakes Mark the Onset of Induced Seismicity in Northeastern Pennsylvania

    2017-12-01

    The link between induced seismicity and injection of hydraulic fracturing wastewater has largely been accepted and corroborated through case studies in Colorado, Arkansas, Texas, and Oklahoma. To date, induced seismicity has largely impacted hydrocarbon-producing regions in the Central United States, while the seismic response in Eastern states, like Pennsylvania, has been relatively muted. In recent years, Pennsylvania exponentially increased hydrocarbon production from the Marcellus and Utica Shales and our results indicate that this activity has triggered an onset of induced seismicity in areas of the state where no previous seismic activity was reported. Three recent earthquakes in Northeastern Pennsylvania directly correlate to hydraulic fracturing activity, though USGS NEIC earthquake catalog locations have vertical errors up to 31km. We present signal analysis results of recorded waveforms of the three identified events and results of a high-precision relocation effort and improvements to the regional velocity model aimed at constraining the horizontal and vertical error in hypocenter position. We show that at least one event is positioned directly along the wellbore track of an active well and correlate its timing to the hydraulic fracturing schedule. Results show that in the absence of wastewater disposal in this area, it is possible to confidently make the connection between the hydraulic fracturing process and induced seismicity.

  6. Resistance and Contingent Contestations to Large-Scale Land Concessions in Southern Laos and Northeastern Cambodia

    Full Text Available Over the last decade, there have been considerable concerns raised regarding the social and environmental impacts of large-scale land concessions for plantation development in various parts of the world, especially in the tropics, including in Laos and Cambodia. However, there is still much to learn about the various connections and interactions associated with reactions to what are often referred to as “land grabs”, and the ways they are associated or not associated with broader social movements and networks opposed to land grabbing. There is also the need to develop language for discussing these circumstances, something I aim to contribute to in this article. Here, I present four different cases of types of resistance, or what I refer to as contingent contestations, to land concessions in southern Laos and northeastern Cambodia (two from each country, focusing on the perspectives and associated strategies of smallholder farmers, but without ignoring broader issues. I consider the roles of locals in these contestations, through emphasizing the importance of histories, identities/ethnicities, politics, and geography in determining the types of responses to these land deals that emerge, and the strategies that are adopted for contesting these developments.

    Observations indicate that over the last few decades there has been a statistically significant increase in precipitation in the northeastern United States and that this can be attributed to an increase in precipitation associated with extreme precipitation events. Here a state-of-the-art atmospheric reanalysis is used to examine such events in detail. Daily extreme precipitation events defined at the 75th and 95th percentile from gridded gauge observations are identified for a selected region within the Northeast. Atmospheric variables from the Modern-Era Retrospective Analysis for Research and Applications, version 2 (MERRA-2), are then composited during these events to illustrate the time evolution of associated synoptic structures, with a focus on vertically integrated water vapor fluxes, sea level pressure, and 500-hectopascal heights. Anomalies of these fields move into the region from the northwest, with stronger anomalies present in the 95th percentile case. Although previous studies show tropical cyclones are responsible for the most intense extreme precipitation events, only 10 percent of the events in this study are caused by tropical cyclones. On the other hand, extreme events resulting from cutoff low pressure systems have increased. The time period of the study was divided in half to determine how the mean composite has changed over time. An arc of lower sea level pressure along the East Coast and a change in the vertical profile of equivalent potential temperature suggest a possible increase in the frequency or intensity of synoptic-scale baroclinic disturbances.

  8. Combining Mineral Identification Techniques to Help Homeowners of Northeastern Connecticut Diagnose Pyrrhotite Laced Concrete Foundations

    Gourley, J. R.; Geiss, C. E.

    2017-12-01

    Crumbling concrete linked to the mineral pyrrhotite is an emerging home owner crisis in northeastern Connecticut as new home foundations are failing within only several years. Potentially thousands of homes that have been built between the mid 1980's and 2016 are affected. Homes have been rendered worthless as basement concrete is crumbling and the cost of repair often exceeds the value of the home. In all of the failing concrete cases the presence of pyrrhotite from a local quarry is the common denominator. Testing for pyrrhotite, until now, has been costly and often invasive, with large core samples required. In working with a local advocacy group, The Connecticut Coalition Against Crumbling Basements (CCACB), we have developed a rapid analysis method that uses a combination of magnetic susceptibility and high resolution X-ray diffraction to identify both the mineral pyrrhotite and/or its expansive product mineral, ettringite. The goal of this method to give homeowners a reliable diagnosis that could help in mitigation decisions and/or the determination of the resale value of their homes. The partnership of Trinity College's Environmental Science Program with the CCACB has built a rewarding bridge between education and the community. Faculty, students and local advocates are collaborating to solve a problem that will help homeowners diagnose a potentially devastating non-natural "geo" hazard that can adversely affect home values where concrete is of an unknown provenance.

    Leptospirosis is a worldwide zoonotic disease. Risk factors for the disease may vary among countries. This study was conducted to determine the risk factors of leptospirosis among febrile cases. A hospital-based cross-sectional study was conducted among 999 febrile patients admitted to 10 hospitals in northeastern Malaysia, from August 2010 to February 2011. An interviewer-guided proforma sheet on sociodemography, type of occupation and social history data was distributed to all adult patients with fever on admission. Serum sample for leptospirosis was screened by IgM Enzyme-linked Immunosorbent Assay (IgM ELISA) test and confirmed by Microscopic Agglutination Test (MAT). The cut-off point for positive MAT was ≥ 1:400 titer in single acute specimens. Seroprevalence of leptospirosis was 8.4% (95% CI: 6.8, 10.3) (n=84/999) by MAT. Multiple logistic regression analysis showed that the high risk occupation group (OR: 1.95, 95% CI: 1.22, 3.13) (p=0.005) and history of recent recreational activity (OR: 2.36, 95% CI: 1.46, 3.85) (pMalaysia. Identification of high risk occupational group and history of recent recreational activity will help to increase the index of suspicion to diagnose leptospirosis among febrile inpatients due to its mimicking other common febrile illnesses in Malaysia.

    Full Text Available Wild plants in forests provide valuable living resources for rural communities. The location where local people harvest various species is important to the wise use of forest ecosystem services. Using global positioning system (GPS tracking of harvesters’ activities as well as geographic information system (GIS and a generalized linear model (GLM, this study analyzed the spatial differences among harvesting sites of three popular edible ferns, i.e., ostrich fern (Matteuccia struthiopteris, bracken (Pteridium aquilinum, and royal fern (Osmunda japonica, in mountainous villages of Northeastern Japan. The explanatory variables used were vegetation classes, terrain features, and proximity to roadways. The GLM yielded clear differences in harvesting sites among species that were affected by both the species’ ecological characteristics and human behavior. Ostrich fern was harvested mainly in canopy openings along valley floors, whereas royal fern harvest sites were frequently located in snow avalanche scrublands. Bracken was mainly harvested in deforested areas or young conifer plantations. Whereas ostrich fern and bracken harvest sites were restricted by the accessibility from roadways, this was not the case for royal fern. Potential harvest sites of ferns were estimated with the highest value for bracken. Our results suggest that local harvesters seriously consider various natural and anthropogenic factors to maintain effective and sustainable harvesting.

    Injection of spent (cooled) thermal fluids began in the Tianjin geothermal district, north-eastern China, at the end of the 1990s. Well injectivities declined after 3-4 years because of self-sealing processes that reduced reservoir permeability. The study focuses on the factors that may have caused the observed decrease in permeability, using chemical and isotopic data on fluids (water and gas) and mineral phases collected from production and injection wells. The results of data processing and interpretation indicate that (1) it is very unlikely that calcite and silica precipitation is taking place in the reservoir; (2) the Fe- and Zn-rich mineral phases (e.g. sulfides, hydroxides and silicates) show positive saturation indexes; (3) SEM and XRD analyses of filtered material reveal that the latter mineral phases are common; (4) visual observation of casings and surface installations, and of corrosion products, suggests that a poor quality steel was used in their manufacture; (5) significant quantities of solids (e.g. quartz and feldspar crystals) are carried by the geothermal fluid; (6) seasonal changes in fluid composition lead to a reduction in casing corrosion during the summer. It was concluded that the decrease in injectivity in the Tianjin wells is caused only in part by the oxidation of casings, downhole pumps, and surface installations, triggered by free oxygen in the injected fluids; the utilization of better quality steels should drastically reduce this type of corrosion. Self-sealing of pores and fractures by reservoir formation solids and by the Fe-corrosion products suspended in the injected fluids seems to be a more important phenomenon, whose effect could be greatly reduced by installing filtering devices at all sites.

    Full Text Available The study examined the relationship between microcredit, microenterprises, and the social welfare of the rural poor in north-eastern Trinidad. Guided by the main propositions of social capital theory, the researchers held 45 semi-structured interviews with active participants/clients within a case study research design. The data showed that access to microcredit through Helping Others Prosper Economically (HOPE positively affected their microenterprises and social welfare, though marginally. Findings also revealed that fragmented social relations within the network, conflict, distrust, and the loose structure of the program limited the impact of their access to microcredit on social welfare as well as the financial potential of the lending organisation, that is, HOPE. It is the contention of this paper, therefore, that such questionable social relations dynamics 'hijack' the promise of collective social networks as exercised through goodwill and resource building. Implications of this study and directions for future research are discussed.

    Full Text Available The northeast Atlantic is a key horizontal and vertical crossroads region for the meridional overturning circulation, but basic nutrient and oxygen fluxes are still poorly constrained by observations in the region. A surface to bottom northeast Atlantic Ocean budget for mass, nutrients (nitrate and phosphate and oxygen is determined using an optimization method based on three surveys of the OVIDE transect (from Greenland to Portugal completed with the World Ocean Atlas 2009. Budgets are derived for two communicating boxes representing the northeastern European basin (NEEB and the Irminger Sea.

    For the NEEB (Irminger box, it is found that 30% of the mass import (export across the OVIDE section reach (originate from the Nordic Seas, while 70% are redistributed between both boxes through the Reykjanes Ridge (9.3 ± 0.7 × 109 kg s−1.

    Net biological source/sink terms of nitrate point to both the Irminger and NEEB boxes as net organic matter production sites (consuming nitrate at a rate of –7.8 ± 6.5 kmol s−1 and –8.4 ± 6.6 kmol s−1, respectively. Using a standard Redfield ratio of C : N = 106 : 16, nitrate consumption rates indicate that about 40 TgC yr−1 of carbon is fixed by organic matter production between the OVIDE transect and the Greenland–Scotland Ridge. Nutrient fluxes also induce a net biological production of oxygen of 73 ± 60 kmol s−1 and 79 ± 62 kmol s−1 in the Irminger and NEEB boxes, which points to the region as being autotrophic.

    The abiotic air–sea oxygen flux leads to an oceanic oxygen uptake in the two regions (264 ± 66 kmol s−1 in the north and 443 ± 70 kmol s−1 in the south. The abiotic flux is partitioned into a mixing and a thermal component. It is found that the Irminger Sea oceanic oxygen uptake is driven by an air–sea heat flux cooling increasing the ocean surface

    Carbapenems are frequently used as a last resort to treat infections caused by multidrug-resistant Gram-negative organisms, thus carbapenem-non-susceptible Enterobacteriaceae (CNSE) is an emerging health threat. To assess risk factors and outcomes of CNSE carriage. We conducted a matched case-control study in six hospitals in North-Eastern France. The controls were patients harbouring carbapenem-susceptible Enterobacteriaceae. Fifty-five cases and 110 controls were included. Most of the CNSE isolates were Enterobacter cloacae and Klebsiella pneumoniae . Carbapenemase production was observed in 40% of isolates and they produced OXA-48 only. CNSE carriage was significantly associated with recent antibiotic use ( P =  0.014), particularly carbapenems ( P =  0.03) and fluoroquinolones ( P =  0.016). A multivariate analysis using conditional logistic regression showed that the presence of concomitant infection(s) (OR: 9.83; 95% CI 3.04-21.39, P =  0.0031), nosocomial infections (OR: 7.84; 95% CI 2.00-12.54, P  =   0.0063) and a high age (OR: 1.07; 95% CI 1.01-1.06, P =  0.038) were independently associated with CNSE carriage. Moreover, patients infected with CNSE had worse outcomes: fewer resolved infections at 1 month ( P =  0.02), and they had a higher mortality rate ( P =  0.0004) and longer hospital stays ( P =  0.02). We identified three independent risk factors for CNSE carriage as well as worse outcomes in infected patients in North-Eastern France. This highlights the importance of early detection of CNSE and the need for antimicrobial therapy re-evaluation after bacteriological analysis has been performed. © The Author 2017.

    Full Text Available We report for the first time the occurrence of organic-walled microfossils in Ediacaran limestones and marls of the Frecheirinha Formation, Ubajara Group, and the first Precambrian acritarchs so far reported for northeastern Brazil. The assemblage of the Frecheirinha Formation represents a low-diversity microflora comprising Leiosphaeridia, Lophosphaeridium and subordinated Bavlinella (=Sphaerocongregus. Their thermal alteration index (TAI between 4+ and 5, suggests metamorphic temperatures exceeding 200-250°C. Higher temperatures are probably related to intruding granitic plutons (Meruoca, Mucambo. Reported δ13C values of carbonates of -3.5 ‰ VPDB (Vienna-Peedee Belemnite at the base, passing up section into a positive plateau of up to +3.7 ‰, and corresponding 87Sr/86Sr values between 0.7075 and 0.7080 suggest an Ediacaran age. The acritarch assemblage is comparable to the Late Ediacaran Leiosphere Palynoflora (LELP or Kotlin-Rovno assemblage, in broad agreement with chemostratigraphic data. Macrofossils belonging to the Ediacara fauna were reported from the overlying Jaibaras Group, which would constrain even further the depositional age of the Frecheirinha Formation to within ca. 575-555 Ma. A more comprehensive palynological study of the Frecheirinha Formation is necessary to confirm this age assignment.

    Full Text Available The aim of this paper was to analyze the distribution of chironomids (Diptera, Chironomidae, and determine their substrate preferences, from two hydrosystems located in northeastern Algeria: the Kebir-East and the Seybouse wadis. Sixty-five species were recorded in 49 sampling sites distributed along the main courses of the two hydrographic nets and their tributaries. The majority of taxa comprised cosmopolitan species widely distributed along these two hydrosystems. Cricotopus (Cricotopus bicinctus showed the highest abundance and frequency of occurrence (29.52% and was widespread in almost all the sampling sites. Species richness ranged from 4 to 23, Shannon diversity between 0.15 and 0.90, Evenness from 0.23 to 1. A cluster analysis was carried out to represent the different groups of sites sharing similar species composition. Agglomerative cluster analysis grouped the sampling sites into four clusters according to the community data. An Indval analysis was then carried out to detect indicator species for each group of the sampling sites. Cricotopus (Isocladius sylvestris was indicator of the first group of the sampling sites. Orthocladius pedestris, Rheocricotopus chalybeatus and C. bicinctus were indicators of the second group, and Polypedilum cultellatum of the third group. The fourth group was not characterized by any species. Indval analysis allowed also to determine species preferences for substrate size: Corynoneura scutellata and Dicrotendipes nervosus emphasized a preference to fine gravel, and Glyptotendipes pallens to fine sand.

This study follows a series of studies on the incidence of thalassemia and other hemoglobinopathies with reduced globin chain synthesis, that were performed during the postwar (1939–45 period in Friuli Venezia Giulia following immigration into the region from Istria and Sardinia (regions of northern and central Italy. Current data show that today’s constantly growing immigration into the region differs from previous decades, in terms of origin and quantity of migrants, who mainly come from third world countries. This has a significant impact on health care issues, and more specifically on prospective health screening for foreigners. The authors conclude that scholastic education and hospital services, either public or private, and voluntary associations, may contribute to solving the problem, but only in terms of training and organization, for non-European Union citizens arriving in northern Italy and neighboring areas, especially those from Africa, Asia, Latin America, and eastern Europe.Keywords: immigration, hemoglobinopathy, pregnancy, trisomy, thalassemia trait, Italy

    In the State of Paraiba, Northeastern Brazil, goat mortality occurred with the ingestion of Plumbago scandens. The fresh plant was then given experimentally to 4 goats at 5, 10, 17.5 or 25 g/kg bw. Depression, anorexia, salivation with foamy saliva, bellowing, bruxism, humpbacked posture, bloat, ruminal atony, continuous lateral head movements, tachycardia, dyspnea and dark brown to black urine were observed in the goats given 17.5 or 25 g/kg bw. The goats receiving 5 or 10 g/kg bw had less severe signs. The goat dosed with 25 g/kg bw died after 18-20 h. All others recovered in 3-9 d. At necropsy of the high dose goat, the main lesions were dark violet to black discoloration of the mucosa of the tongue, esophagus, reticulum and ventral sac of the rumen, and gelatinous edema in the visceral ruminal peritoneum. Histologically the reticulum and ventral rumen sac had diffuse epithelial necrosis and severe edema and neutrophilic infiltration of the submucosa. Separation of the ruminal epithelium from the submucosa was observed. Epithelial degeneration and necrosis was also seen in the omasum, esophagus and tongue. Reproduction of the disease with clinical signs similar to those observed by the farmer in the spontaneously affected goats suggests that the clinical mortality was caused by ingestion of Plumbago scandens.

    In order to document medicinal uses of plants in the northeastern of Algeria, preserve traditional heritage and highlighted the risks of excessive human exploitation on flora and biodiversity of the region, an inventory of medicinal species existed in the traditional pharmacopoeia in Skikda region (north-east of Algeria) was made. The survey was carried out during the year (2015-2016), through face to face interviews, using pre-prepared questionnaire. The form contains: sociodemorgaphic profile of each respondent (sex, age, educational level and monthly income), local name of medicinal species used, uses, used parts and methods of preparations. A total of 90 species belonging to 42 botanical families, were listed. The analysis of the obtained results showed that the frequency of use of medicinal plants is related to the age, sex, educational level and monthly income of our respondents. It was recorded that the majority of remedies are prepared in the form of a decoctate from the leaves of the different species, in order to treat a wide range of diseases especially those of the digestive tract. Local population has a rich indigenous knowledge, but is always stays not adequately documented. It should be noted that some listed species are suffering from surexploitation which can subjects to the disappearance of the most vulnerable species. It will be urgent and essential to adopt a sustainable management strategy to avoid the degradation of biodiversity of the region. Copyright © 2017 Elsevier GmbH. All rights reserved.

    A quantitative measure by play fairway analysis in geothermal energy development is an important tool that can present the probability map of potential resources through the uncertainty studies in geology for early phase decision making purpose in the related industries. While source, pathway, and fluid are the three main geologic factors in traditional geothermal systems, identifying the heat paths is critical to reduce drilling cost. Taiwan is in East Asia and the western edge of Pacific Ocean, locating on the convergent boundary of Eurasian Plate and Philippine Sea Plate with many earthquake activities. This study chooses a metamorphic area in the western corner of Yi-Lan plain in northeastern Taiwan with high geothermal potential and several existing exploration sites. Having high subsurface temperature gradient from the mountain belts, and plenty hydrologic systems through thousands of millimeters annual precipitation that would bring up heats closer to the surface, current geothermal conceptual model indicates the importance of pathway distribution which affects the possible concentration of extractable heat location. The study conducts surface lineation analysis using analytic hierarchy process to determine weights among various fracture types for their roles in geothermal pathways, based on the information of remote sensing data, published geologic maps and field work measurements, to produce regional fracture distribution probability map. The results display how the spatial distribution of pathways through various fractures could affect geothermal systems, identify the geothermal plays using statistical data analysis, and compare against the existing drilling data.

    The Frangensko Plateau is located in the northeastern part of Bulgaria and covers an area of 360 km2. On the territory of the plateau there are two protected areas, as well as two areas of the European ecological network NATURA 2000. The study of the medicinal plants on the territory of the Frangensko Plateau is made for the first time. As a result of our research we found 362 species of vascular plants from 242 genera and 80 families. The most of the families and the genera are represented by a small number of inferior taxa. The analysis of their life form indicates that the hemicryptophytes dominate with 39.50%, followed by the phanerophytes (22.10%). The biological types are represented mainly by perennial herbaceous plants (52.21%), annual herbaceous plants (14.09%) and trees (10.50%). There are 8 types of floristic elements divided in 32 groups. The largest percentage of species is of European type (51.93%). Among the medicinal plants, there are two Balkan endemic species, one Bulgarian endemic species and 30 relic species. Thirty four species with protection statute are described. The anthropophytes among the medicinal plants are 242 species (66.85%).

    Full Text Available The dry forests of northeastern Brazil are found near the coastal zone and on low, isolated mountains inland amid semi-arid vegetation. The floristic composition of these dry montane forests, as well as their relationship to humid forests (Atlantic forest sensu stricto and to the deciduous thorn woodlands (Caatinga sensu stricto of the Brazilian northeast are not yet well known. This paper sought to determine if the arboreal plants in a dry forest growing on a low mountain in the semi-arid inland region (Serra Negra, 8° 35’ - 8° 38’ S and 38° 02’ - 38° 04’ W between the municipalities of Floresta and Inajá, state of Pernambuco have the same floristic composition and structure as that seen in other regional forests. In fifty 10 x 20 m plots all live and standing dead trees with trunk measuring > 5 cm diameter at breast height were measured. Floristic similarities between the forest studied and other regional forests were assessed using multivariate analysis. The results demonstrate that the dry forest studied can be classified into two groups that represent two major vegetational transitions: (1 a humid forest/dry forest transition; and (2 a deciduous thorn-woodland/ dry forest transition.

    Full Text Available The objective of this study was to evaluate the population genetic structure of Nellore cattle in northeastern Brazil. Pedigree information was collected from 175,231 animals born from 1967 to 2007. Probability of gene origin, inbreeding, average relatedness coefficient (AR, completeness pedigree, effective population size and generation interval were calculated. Generation interval was high due to the long period of time animals were used as reproducers. The bottleneck effect was evidenced as a result of intensive use of limited breeders over the last years. Low values were observed ​​in the effective number of founder animals (434 and ancestors (427 comparing with the number on the base (175,231 and reference populations (130,038. Generally, the variability explained by the founders and ancestors is considered low. The average coefficient of inbreeding (0.11% and AR (0.14% estimated for this population is considered low and can be partly explained by the increased population effective number in recent periods; however, it may be underestimated by shallow pedigree.

    Full Text Available ABSTRACT Bacterial fruit blotch (BFB of cucurbit plants is caused by Acidovorax citrulli and represents a serious concern to melon (Cucumis melo L. growers worldwide, including those in Brazil. Thirty-four A. citrulli strains from different melon production areas of northeastern Brazil were characterized for their virulence on melon fruits and their substrate utilization and molecular profiles. Based on the analysis of BFB severity on melon fruits, the A. citrulli strains were divided into three groups, classified as mildly, moderately or highly virulent. Although host-related groups were not observed, the watermelon and ‘melão-pepino’ strains exhibited only low or moderate virulence on melon fruit. Substrate utilization profiles revealed that 94 % of the 95 tested compounds were used by A. citrulli strains as a carbon source. Overall, based on substrate utilization, low variability was observed with no relationship to host of origin. The formation of one group of A. citrulli strains based on Repetitive Sequence-based PCR (rep-PCR analysis confirmed the low variability observed in the substrate utilization analyses. Bayesian inference based on the analysis of 23S rDNA partial sequence data resulted in one well-supported clade and clustered the strains with the A. citrulli-type species with high posterior probability support. Based on the markers used, the Brazilian A. citrulli strains belong to a single group, which corresponds to the previously described Group I for this bacterium in the United States.

    Understanding the deep-sea ecosystem functioning is a key issue in the study of ocean sciences. Bringing together researchers from several scientific domains, the BIOMETORE project aims to the increase knowledge on deep-sea ecosystems and biodiversity at the Atlantic seamounts of the Madeira-Tore and Great Meteor geological complexes. The project outputs will provide important information for the understanding and sustainable management of the target seamount ecosystems, thus contributing to fulfill knowledge gaps on their biodiversity, from bacteria to mammals, and food webs, as well as to promote future sustainable fisheries and sea-floor integrity. The plan includes the realization of eight multidisciplinary surveys, four done during the summer of 2015 and another four planned for the same season of 2016, in target seamounts: the Gorringe bank, the Josephine, and others in the Madeira-Tore, and selected ones in the Greta Meteor (northeastern Atlantic Ocean). The surveys cover a number of scientific areas in the domains of oceanography, ecology, integrative taxonomy, geology, fisheries and spatial mapping. We present and discuss BIOMETORE developments, the preliminary results from the four 2015 summer surveys, and the planning of the next four surveys.

    Forests provide important climate forcing through biogeochemical and biogeophysical processes. In this study, we investigated the climatic effects of forest disturbances due to changes in forest biomass and surface albedo in terms of radiative forcing over northeastern China. Four types of forest disturbances were considered: fires, insect damage, logging, and afforestation and reforestation. The mechanisms of the influence of forest disturbances on climate were different. ‘Instantaneous’ net radiative forcings caused by fires, insect damage, logging, and afforestation and reforestation were estimated at 0.53 ± 0.08 W m −2 , 1.09 ± 0.14 W m −2 , 2.23 ± 0.27 W m −2 , and 0.14 ± 0.04 W m −2 , respectively. Trajectories of CO 2 -driven radiative forcing, albedo-driven radiative forcing, and net forcing were different with time for each type of disturbance. Over a decade, the estimated net forcings were 2.24 ± 0.11 W m −2 , 0.20 ± 0.31 W m −2 , 1.06 ± 0.41 W m −2 , and −0.47 ± 0.07 W m −2 , respectively. These estimated radiative forcings from satellite observations provided evidence for the mechanisms of the influences of forest disturbances on climate. (paper)

    Full Text Available An outbreak characterized by vomiting and rapid progression to unconsciousness and death was reported in Sylhet Distrct in northeastern Bangladesh following destructive monsoon floods in November 2007.We identified cases presenting to local hospitals and described their clinical signs and symptoms. We interviewed patients and their families to collect illness histories and generate hypotheses about exposures associated with disease. An epidemiological study was conducted in two outbreak villages to investigate risk factors for developing illness. 76 patients were identified from 9 villages; 25% (19/76 died. Common presenting symptoms included vomiting, elevated liver enzymes, and altered mental status. In-depth interviews with 33 cases revealed that 31 (94% had consumed ghagra shak, an uncultivated plant, in the hours before illness onset. Ghagra shak was consumed as a main meal by villagers due to inaccessibility of other foods following destructive monsoon flooding and rises in global food prices. Persons who ate this plant were 34.2 times more likely (95% CI 10.2 to 115.8, p-value<0.000 than others to develop vomiting and unconsciousness during the outbreak in our multivariate model. Ghagra shak is the local name for Xanthium strumarium, or common cocklebur.The consumption of Xanthium strumarium seedlings in large quantities, due to inaccessibility of other foods, caused this outbreak. The toxic chemical in the plant, carboxyatratyloside, has been previously described and eating X. strumarium seeds and seedlings has been associated with fatalities in humans and livestock. Unless people are able to meet their nutritional requirements with safe foods, they will continue to be at risk for poor health outcomes beyond undernutrition.

    The Centro di Ricerche Sismologiche (CRS, Seismological Research Centre) of the Istituto Nazionale di Oceanografia e di Geofisica Sperimentale (OGS, Italian National Institute for Oceanography and Experimental Geophysics) in Udine (Italy) after the strong earthquake of magnitude M=6.4 occurred in 1976 in the Italian Friuli-Venezia Giulia region, started to operate the North-eastern Italy Seismic Network: it currently consists of 17 very sensitive broad band and 18 simpler short period seismic stations, all telemetered to and acquired in real time at the OGS-CRS data centre in Udine. Real time data exchange agreements in place with other Italian, Slovenian, Austrian and Swiss seismological institutes lead to a total number of about 100 seismic stations acquired in real time, which makes the OGS the reference institute for seismic monitoring of North-eastern Italy. The south-western edge of the OGS seismic network (Fig. 1) stands on the Po alluvial basin: earthquake localization and characterization in this area is affected by the presence of soft alluvial deposits. OGS ha already experience in running a local seismic network in high noise conditions making use of borehole installations in the case of the micro-seismicity monitoring of a local gas storage site for a private company. Following the ML = 5.9 earthquake that struck the Emilia region around Ferrara in Northern Italy on 20 May 2012 at 02:03:53 UTC, a cooperation of Istituto Nazionale di Geofisica e Vulcanologia, OGS, the Comune di Ferrara and the University of Ferrara lead to the reinstallation of a previously existing very broad band (VBB) borehole seismic station in Ferrara. The aim of the OGS intervention was on one hand to extend its real time seismic monitoring capabilities toward South-West, including Ferrara and its surroundings, and on the other hand to evaluate the seismic response at the site. We will describe improvements in running the North-eastern Italy Seismic Network, including details of

    Visceral leishmaniasis (VL) is a systemic disease endemic in tropical countries and transmitted through sand flies. In particular, Canis familiaris (or domesticated dogs) are believed to be a major urban reservoir for the parasite causing the disease Leishmania. The average number of human VL cases was 58 per year in the state of Sergipe. The city of Aracaju, capital of Sergipe in Northeastern Brazil, had 159 cases of VL in humans. Correlatively, the percentage of serologically positive dogs for leishmaniasis increased from 4.73% in 2008 to 12.69% in 2014. Thus, these studies aimed to delineate the spatial distribution and epidemiological aspects of human and canine VL as mutually supportive for increased incidence. The number of human cases of VL and the frequency of canine positive serology for VL both increased between 2008 and 2014. Spatial distribution analyses mapped areas of the city with the highest concentration of human and canine VL cases. The neighbourhoods that showed the highest disease frequency were located on the outskirts of the city and in urbanised areas or subjected to development. Exponential increase in VL-positive dogs further suggests that the disease is expanding in urban areas, where it can serve as a reservoir for transmission of dogs to humans via the sand fly vector.

    Full Text Available Surface vertical deformation includes the Earth’s elastic response to mass loading on or near the surface. Continuous Global Positioning System (CGPS stations record such deformations to estimate seasonal and secular mass changes. We used 41 CGPS stations to construct a time series of coordinate changes, which are decomposed by empirical orthogonal functions (EOFs, in northeastern Tibet. The first common mode shows clear seasonal changes, indicating seasonal surface mass re-distribution around northeastern Tibet. The GPS-derived result is then assessed in terms of the mass changes observed in northeastern Tibet. The GPS-derived common mode vertical change and the stacked Gravity Recovery and Climate Experiment (GRACE mass change are consistent, suggesting that the seasonal surface mass variation is caused by changes in the hydrological, atmospheric and non-tidal ocean loads. The annual peak-to-peak surface mass changes derived from GPS and GRACE results show seasonal oscillations in mass loads, and the corresponding amplitudes are between 3 and 35 mm/year. There is an apparent gradually increasing gravity between 0.1 and 0.9 μGal/year in northeast Tibet. Crustal vertical deformation is determined after eliminating the surface load effects from GRACE, without considering Glacial Isostatic Adjustment (GIA contribution. It reveals crustal uplift around northeastern Tibet from the corrected GPS vertical velocity. The unusual uplift of the Longmen Shan fault indicates tectonically sophisticated processes in northeastern Tibet.

    Future climate change impacts on humans will be determined by the convergence of evolving physical climate and socioeconomic systems. Of particular concern is the intersection of extreme events and vulnerable populations. Rural areas of the Northeastern United States have experienced increased temperature and precipitation extremes, especially over the past three decades, and face unique challenges due to their physical isolation, natural resources dependent economies, and high poverty rates. To explore the impacts of future extreme events on vulnerable, rural populations in the Northeast, we project extreme events and vulnerability indicators to identify where changes in extreme events and vulnerable populations coincide. Specifically, we analyze future (2046-2075) maximum annual daily temperature, minimum annual daily temperature, maximum annual daily precipitation, and maximum consecutive dry day length for Representative Concentration Pathways (RCP) 4.5 and 8.5 using four global climate models (GCM) and a gridded observational dataset. We then overlay those projections with estimates of county-level population and relative income for 2060 to calculate changes in person-events from historical (1976-2005), with a focus on Northeast counties that have less than 250,000 people and are in the bottom income quartile. We find that across the rural Northeast for RCP4.5, heat person-events per year increase tenfold, far exceeding decreases in cold person-events and relatively small changes in precipitation and drought person-events. Counties in the bottom income quartile have historically (1976-2005) experienced a disproportionate number of heat events, and counties in the bottom two income quartiles are projected to experience a greater heat event increase by 2046-2075 than counties in the top two income quartiles. We further explore the relative contributions of event frequency, population, and income changes to the total and geographic distribution of climate change

    Understanding influences of cumulative effects from multiple stressors in marine ecosystems requires an understanding of the sources for and scales of variability. A multidisciplinary ecosystem study in the offshore northeastern Chukchi Sea during 2008-2013 investigated the variability of the study area's two adjacent sub-ecosystems: a pelagic system influenced by interannual and/or seasonal temporal variation at large, oceanographic (regional) scales, and a benthic-associated system more influenced by small-scale spatial variations. Variability in zooplankton communities reflected interannual oceanographic differences in waters advected northward from the Bering Sea, whereas variation in benthic communities was associated with seafloor and bottom-water characteristics. Variations in the planktivorous seabird community were correlated with prey distributions, whereas interaction effects in ANOVA for walruses were related to declines of sea-ice. Long-term shifts in seabird distributions were also related to changes in sea-ice distributions that led to more open water. Although characteristics of the lower trophic-level animals within sub-ecosystems result from oceanographic variations and interactions with seafloor topography, distributions of apex predators were related to sea-ice as a feeding platform (walruses) or to its absence (i.e., open water) for feeding (seabirds). The stability of prey resources appears to be a key factor in mediating predator interactions with other ocean characteristics. Seabirds reliant on highly-variable zooplankton prey show long-term changes as open water increases, whereas walruses taking benthic prey in biomass hotspots respond to sea-ice changes in the short-term. A better understanding of how variability scales up from prey to predators and how prey resource stability (including how critical prey respond to environmental changes over space and time) might be altered by climate and anthropogenic stressors is essential to

  1. Uranium and Thorium in zircon sands processed in Northeastern Brazil

    Zircon the main mineral of zirconium is a silicate mineral product (ZrSiO 4 ) obtained from beach sand deposits, along with other minerals such as kyanite, ilmenite, and rutile. All zircons contain some radioactive impurities due to the presence of uranium, thorium and their respective decay products in the crystalline structure of zircon, as well as potassium-40. Uranium and thorium substitute Zr 4+ in the mineral through an internal process called isomorphous replacement of zirconium. For this study, samples were collected both from a mineral sand processing plant located in the coastal region of Northeastern brazil and from the beach sands used in the process. The aim of this study was to assess the 238 U, 232 Th and 40 K contents in the beach sands and in the mineral products extracted from the sands in that facility, with special emphasis on zircon. Measurements were performed through gamma spectrometry, by using a high-purity germanium detector (HPGe) coupled to a multichannel analyzer. Activity concentration for 238 U and 232 Th in zircon sands ranged from 5462±143 to 19286±46 Bq kg -1 and from 1016±7 to 7162±38 Bq kg -1 , respectively. For 40 K, on the other hand, activity concentration values ranged from 81±14 to 681±26 Bq Kg -1 . The results of the measurements carried out for raw sand samples showed activity concentrations between 2.7±0.6 and 7.9±0.9 Bq kg -1 and 6.5±0.4 and 9.4±0.6 Bq kg -1 for 238 U and 23T h respectively, and from 48.8±3.1 to 76.1±2.4 Bq kg -1 for 40 K. Activity concentrations of 238 U and 232 Th in kyanite, ilmenite and rutile samples were also determined. (author)

  2. Weak positive cloud-to-ground flashes in Northeastern Colorado

    1991-01-01

    The frequency distributions of the peak magnetic field associated with the first detected return stroke of positive and negative cloud-to-ground (CG) flashes were studied using lightning data from northeastern Colorado. These data were obtained during 1985 with a medium-to-high gain network of three direction finders (DF's). The median signal strength of positive flashes was almost two times that of the negatives for flashes within 300 km of the DF's, which have an inherent detection-threshold bias that tends to discriminate against weak signals. This bias increases with range, and affects the detection of positive and negative flashes in different ways, because of the differing character of their distributions. Positive flashes appear to have a large percentage of signals clustered around very weak values that are lost to the medium-to-high gain Colorado Detection System very quickly with increasing range. The resulting median for positive signals could thus appear to be much larger than the median for negative signals, which are more clustered around intermediate values. When only flashes very close to the DF's are considered, however, the two distributions have almost identical medians. The large percentage of weak positive signals detected close to the DF's has not been explored previously. They have been suggested to come from intracloud discharges and thus are improperly classified as CG flashes. Evidence in hand, points to their being real positive, albeit weak CG flashes. Whether or not they are real positive ground flashes, it is important to be aware of their presence in data from magnetic DF networks.

    Interpretation of the aeromagnetic survey of northeastern Cuba at scale 1 50 000 is presented. Mainly ophiolitic rocks are characterized by a high magnetic response. The aeromagnetic data was reduced to the pole and the horizontal and vertical gradients, as well as the upward continuation were calculated. To define areas of serpentinized ultrabasic rocks at surface and depth, the magnetic field transformations were interpreted. We discuss lateral extension of outcrops, thickness variation of the ophiolitic rocks, basement extension and fault zones. Hydrothermal alterations indicate associated precious metal secondary mineralization. Operations are planned to limit damage to mining by siliceous material in Fe+Ni laterites. [Spanish] Cuba, en la cual afloran fundamentalmente rocas ofioliticas caracterizadas por un alto grado de magnetizacion. Los datos aeromagneticos fueron reducidos al polo y luego se realizaron los calculos de gradientes horizontales y verticales y la continuacion analitica ascendente. A partir de los resultados de estas transformaciones se delimitaron zonas donde predominan las rocas ultrabasicas serpentinizadas tanto en superficie como en profundidad, definiendose la extension lateral de estas rocas por debajo de las rocas que afloran en superficie. Tambien se estimaron las variaciones de los espesores de las rocas ofioliticas, el basamento de las rocas que afloran, la presencia de estructuras disyuntivas, y se proponen nuevas estructuras de este tipo. Por ultimo se delimitan las zonas de alteracion hidrotermal, lo cual posee gran importancia, ya que con las mismas se pueden vincular mineralizaciones de metales preciosos. Ademas, su delimitacion en depositos lateriticos permite orientar los trabajos de explotacion minera, teniendo en cuenta el dano que causa al proceso metalurgico la presencia de material silicio en las lateritas Fe+Ni.

    Full Text Available Background: The northeastern region (NER of India is geographically isolated and ethno-culturally different from the rest of the country. There is lacuna regarding the data on causes of blindness and severe visual impairment in children from this region. Aim: To determine the causes of severe visual impairment and blindness amongst children from schools for the blind in the four states of NER of India. Design and Setting: Survey of children attending special education schools for the blind in the NER. Materials and Methods: Blind and severely visually impaired children (best corrected visual acuity < 20/200 in the better eye, aged up to 16 years underwent visual acuity estimation, external ocular examination, retinoscopy and fundoscopy. Refraction and low vision workup was done where indicated. World Health Organization′s reporting form was used to code anatomical and etiological causes of visual loss. Statistical Analysis: Microsoft Excel Windows software with SPSS. Results: A total of 376 students were examined of whom 258 fulfilled the eligibility criteria. The major anatomical causes of visual loss amongst the 258 were congenital anomalies (anophthalmos, microphthalmos 93 (36.1%; corneal conditions (scarring, vitamin A deficiency 94 (36.7%; cataract or aphakia 28 (10.9%, retinal disorders 15 (5.8% and optic atrophy 14 (5.3%. Nearly half of the children were blind from conditions which were either preventable or treatable (48.5%. Conclusion: Nearly half the childhood blindness in the NER states of India is avoidable and Vitamin A deficiency forms an important component unlike other Indian states. More research and multisectorial effort is needed to tackle congenital anomalies.

  6. Epidemiological analysis of human fascioliasis in northeastern Punjab, Pakistan.

    2016-04-01

    A coprological study was performed to assess human fascioliasis in 7200 subjects inhabiting rural communities of localities close to the capital city of Lahore in the northeastern part of the very highly populated Punjab province, Pakistan, a country where human infection had never been reported before 2005. The analysis of 1200 subjects including 50 subjects/month throughout a two-year study in each of six localities surveyed provided an overall prevalence of 1.18%, with a range between 0.67% and 1.75% according to localities. Infection rates did not differ according to gender, excepting a higher rate in females (1.13% vs 0.77%) in one locality. Prevalences according to age groups proved to be higher in 11-20 years with 1.57%, followed by 1.18% in 0-10 years and 0.47% in 21-30 years, while no infection above 30 years. Seasonal prevalences proved to be significantly different when comparing summer and autumn with winter and spring. Monthly prevalences showed two peaks, the highest in August (4.67%) and another in January (2.17%). Correlation studies of monthly prevalences with temperature, humidity, rainfall, and pan evaporation showed significant results only with humidity. Despite prevalences being low, the very high number of inhabitants and population densities of the areas surveyed suggest a wide public health problem potentially infecting up to 150,000 rural people, children included, only in the respective districts. Additionally, the situation becomes of more concern when considering the present climate change trend affecting the Punjab, which indicates a progressively increasing fascioliasis transmission risk in that animal endemic area in the near future.

  7. Grizzly bear predation rates on caribou calves in northeastern Alaska

    Young, Donald D.; McCabe, Thomas R.

    1997-01-01

    During June 1993 and 1994, 11 radiocollared and 7 unmarked grizzly bears (Ursus arctos) were monitored visually (observation) from fixed-wing aircraft to document predation on calves of the Porcupine Caribou (Rangifer tarandus) Herd (PCH) in northeastern Alaska. Twenty-six (72%) grizzly bear observations were completed (???60 min) successfully (median duration = 180 min; ??95% CI = 136-181 min; range = 67-189 min) and 10 were discontinued (duration ???24 min) due to disturbance to the bear, or unfavorable weather conditions. Of the 26 successfully completed observations, 15 (58%) included predatory activity (encounter) directed at caribou calves and 8 (31%) included kills. Of 32 encounters, 9 resulted in kills, for a success rate of 28%. The median duration of encounters was 1 minute (??95% CI = 1-2 min; range = 1-6 min; n = 32;), and the median time spent at a kill was 14 minutes (??95% CI = 9-23 min; range = 6-56 min; n = 9). Sows with young (n = 4) killed more frequently (75%; P = 0.0178) than barren sows, boars, and consorting pairs combined (17%; n = 18). Estimated kill rate was highest for sows with young (6.3 kills/bear/day; n = 4), followed by barren sows (4.6 kills/bear/day; n = 5), boars (1.9 kills/bear/day; n = 5), and, finally, consorting pairs (1.0 kills/bear/day; n = 8). Estimated kill rate obtained via conventional radiotracking point surveys (4.8 kills/bear/day) was higher than that obtained via concurrent bear observations (3.1 kills/bear/day). Our research provides baseline estimates of predation rates by grizzly bears on caribou calves that will enhance the capability of wildlife professionals in managing populations of both predators and their prey.

  8. There is no evidence for a temporal link between pathogen arrival and frog extinctions in north-eastern Australia.

    Directory of Open Access Journals (Sweden)

    Ben L Phillips

    Full Text Available Pathogen spread can cause population declines and even species extinctions. Nonetheless, in the absence of tailored monitoring schemes, documenting pathogen spread can be difficult. In the case of worldwide amphibian declines the best present understanding is that the chytrid fungus Batrachochytrium dendrobatidis (Bd has recently spread, causing amphibian declines and extinction in the process. However, good evidence demonstrating pathogen arrival followed by amphibian decline is rare, and analysis of putative evidence is often inadequate. Here we attempt to examine the relationship between Bd arrival and amphibian decline across north-eastern Australia, using sites where a wave-like pattern of amphibian decline was first noticed and at which intensive research has since been conducted. We develop an analytical framework that allows rigorous estimation of pathogen arrival date, which can then be used to test for a correlation between the time of pathogen arrival and amphibian decline across sites. Our results show that, with the current dataset, the earliest possible arrival date of Bd in north-eastern Australia is completely unresolved; Bd could have arrived immediately before sampling commenced or may have arrived thousands of years earlier, the present data simply cannot say. The currently available data are thus insufficient to assess the link between timing of pathogen arrival and population decline in this part of the world. This data insufficiency is surprising given that there have been decades of research on chytridiomycosis in Australia and that there is a general belief that the link between Bd arrival and population decline is well resolved in this region. The lack of data on Bd arrival currently acts as a major impediment to determining the role of environmental factors in driving the global amphibian declines, and should be a major focus of future research.

  9. Bivergent thrust wedges surrounding oceanic island arcs: Insight from observations and sandbox models of the northeastern caribbean plate

    2009-01-01

    At several localities around the world, thrust belts have developed on both sides of oceanic island arcs (e.g., Java-Timor, Panama, Vanuatu, and the northeastern Caribbean). In these localities, the overall vergence of the backarc thrust belt is opposite to that of the forearc thrust belt. For example, in the northeastern Caribbean, a north-verging accretionary prism lies to the north of the Eastern Greater Antilles arc (Hispaniola and Puerto Rico), whereas a south-verging thrust belt called the Muertos thrust belt lies to the south. Researchers have attributed such bivergent geometry to several processes, including: reversal of subduction polarity; subduction-driven mantle flow; stress transmission across the arc; gravitational spreading of the arc; and magmatic inflation within the arc. New observations of deformational features in the Muertos thrust belt and of fault geometries produced in sandbox kinematic models, along with examination of published studies of island arcs, lead to the conclusion that the bivergence of thrusting in island arcs can develop without reversal of subduction polarity, without subarc mantle flow, and without magmatic inflation. We suggest that the Eastern Greater Antilles arc and comparable arcs are simply crustalscale bivergent (or "doubly vergent") thrust wedges formed during unidirectional subduction. Sandbox kinematic modeling suggests, in addition, that a broad retrowedge containing an imbricate fan of thrusts develops only where the arc behaves relatively rigidly. In such cases, the arc acts as a backstop that transmits compressive stress into the backarc region. Further, modeling shows that when arcs behave as rigid blocks, the strike-slip component of oblique convergence is accommodated entirely within the prowedge and the arc-the retrowedge hosts only dip-slip faulting ("frontal thrusting"). The existence of large retrowedges and the distribution of faulting in an island arc may, therefore, be evidence that the arc is

    Social networks have increased in recent decades, and with them the bullying, causing difficulties in young people's mental health expressed through depressive symptoms, suicidal ideation and suicide attempts. Up next, we present a case that exemplifies this situation. To describe a case report that exemplifies this new outlook in young people and how it affects their mental health. Case report and non-systematic literature review. One case report, treated at a hospital in Medellin due to two suicide attempts related to social networks is presented. Currently, there are multiple social media resources, the advent of internet and smartphones is not only a strategy for improving social interactions, but it also contributes to impair mental health of some vulnerable young people. This case sensitize us, about the relationship between the growing social networking and cyberbullying as well as suicidal thoughts / attempts; thanks to this case and the available literature, we can't establish causality but we could deduce that the internet utter a increased risk for young people who are exposed and more vulnerable.

    While some studies have suggested associations between shift work and obesity, few have been population-based or considered multiple shift schedules. Since obesity is linked with several chronic health conditions, understanding which types of shift work influence obesity is important and additional work with more detailed exposure assessment of shift work is warranted. Using multivariate polytomous logistic regression, we investigated the associations between shift work (evening/night, rotating and other shift schedules) and overweight and obesity as measured by body mass index cross-sectionally among 1561 men. These men had previously participated as population controls in a prostate cancer case-control study conducted in northeastern Ontario from 1995 to 1999. We obtained information on work history (including shift work), height and weight from the existing self-reported questionnaire data. We observed an association for ever (vs. never) having been employed in rotating shift work for both the overweight (OR [odds ratio] = 1.34; 95% CI [confidence interval]: 1.05-1.73) and obese (OR = 1.57; 95% CI: 1.12-2.21) groups. We also observed nonsignificant associations for ever (vs. never) having been employed in permanent evening/night shifts. In addition, we found a significant trend of increased risk for both overweight and obesity with increasing duration of rotating shift work. Both the positive association between rotating shift work and obesity and the suggested positive association for permanent evening/night shift work in this study are consistent with previous findings. Future population-based research that is able to build on our results while examining additional shift work characteristics will further clarify whether some shift patterns have a greater impact on obesity than others.

    Emissions from the potential installation of distributed energy resources (DER) in the place of current utility-scale power generators have been introduced into an emissions inventory of the northeastern United States. A methodology for predicting future market penetration of DER that considers economics and emission factors was used to estimate the most likely implementation of DER. The methodology results in spatially and temporally resolved emission profiles of criteria pollutants that are subsequently introduced into a detailed atmospheric chemistry and transport model of the region. The DER technology determined by the methodology includes 62% reciprocating engines, 34% gas turbines, and 4% fuel cells and other emerging technologies. The introduction of DER leads to retirement of 2625 MW of existing power plants for which emissions are removed from the inventory. The air quality model predicts maximum differences in air pollutant concentrations that are located downwind from the central power plants that were removed from the domain. Maximum decreases in hourly peak ozone concentrations due to DER use are 10 ppb and are located over the state of New Jersey. Maximum decreases in 24-hr average fine particulate matter (PM2.5) concentrations reach 3 microg/m3 and are located off the coast of New Jersey and New York. The main contribution to decreased PM2.5 is the reduction of sulfate levels due to significant reductions in direct emissions of sulfur oxides (SO(x)) from the DER compared with the central power plants removed. The scenario presented here represents an accelerated DER penetration case with aggressive emission reductions due to removal of highly emitting power plants. Such scenario provides an upper bound for air quality benefits of DER implementation scenarios.

    JC Santos

    Full Text Available We report on the richness of galling insects in the altitudinal wetland forests of Pernambuco State, Northeastern Brazil. We found 80 distinct types of insect galls on 49 species of host plants belonging to 28 families and 35 genera. Most of the galled plant species belong to Nyctaginaceae, Fabaceae, Meliaceae, Sapindaceae and Myrtaceae. The most common gall were spheroid and globoid; most galls were glabrous, predominantly green and with one chamber, and on the leaves. Most galls were induced by Cecidomyiidae (Diptera. The results of this study contribute to existing knowledge richness of galling insects and host-plant diversity in the altitudinal wetland forests of Northeastern Brazil.

    Full Text Available ABSTRACT: Milk samples from 16 cows that tested positive on the tuberculin test in the state of Paraíba, northeastern Brazil, were used for mycobacteria isolation and identification. Mycobacteria were isolated from five (31.25% of the 16 milk samples; three samples were classified as M. bovis, and two as belonging to the Mycobacterium genus. This is probably the first study of isolation and identification of M. bovis in milk from cows in Northeastern Brazil, which suggests that humans are at risk of contamination by ingestion.

    Full Text Available During 2015 to 2016, Brazil reported more Zika virus (ZIKV cases than any other country, yet population exposure remains unknown. Serological studies of ZIKV are hampered by cross-reactive immune responses against heterologous viruses. We conducted serosurveys for ZIKV, dengue virus (DENV, and Chikungunya virus (CHIKV in 633 individuals prospectively sampled during 2015 to 2016, including microcephaly and non-microcephaly pregnancies, HIV-infected patients, tuberculosis patients, and university staff in Salvador in northeastern Brazil using enzyme-linked immunosorbent assays (ELISAs and plaque reduction neutralization tests. Sera sampled retrospectively during 2013 to 2015 from 277 HIV-infected patients were used to assess the spread of ZIKV over time. Individuals were georeferenced, and sociodemographic indicators were compared between ZIKV-positive and -negative areas and areas with and without microcephaly cases. Epidemiological key parameters were modeled in a Bayesian framework. ZIKV seroprevalence increased rapidly during 2015 to 2016, reaching 63.3% by 2016 (95% confidence interval [CI], 59.4 to 66.8%, comparable to the seroprevalence of DENV (75.7%; CI, 69.4 to 81.1% and higher than that of CHIKV (7.4%; CI, 5.6 to 9.8%. Of 19 microcephaly pregnancies, 94.7% showed ZIKV IgG antibodies, compared to 69.3% of 257 non-microcephaly pregnancies (P = 0.017. Analyses of sociodemographic data revealed a higher ZIKV burden in low socioeconomic status (SES areas. High seroprevalence, combined with case data dynamics allowed estimates of the basic reproduction number R0 of 2.1 (CI, 1.8 to 2.5 at the onset of the outbreak and an effective reproductive number Reff of <1 in subsequent years. Our data corroborate ZIKV-associated congenital disease and an association of low SES and ZIKV infection and suggest that population immunity caused cessation of the outbreak. Similar studies from other areas will be required to determine the fate of the American

  19. Simulation of water quality for Salt Creek in northeastern Illinois

    Melching, Charles S.; Chang, T.J.

    1996-01-01

    Water-quality processes in the Salt Creek watershed in northeastern Illinois were simulated with a computer model. Selected waste-load scenarios for 7-day, 10-year low-flow conditions were simulated in the stream system. The model development involved the calibration of the U.S. Environmental Protection Agency QUAL2E model to water-quality constituent concentration data collected by the Illinois Environmental Protection Agency (IEPA) for a diel survey on August 29-30, 1995, and the verification of this model with water-quality constituent concentration data collected by the IEPA for a diel survey on June 27-28, 1995. In-stream measurements of sediment oxygen demand rates and carbonaceous biochemical oxygen demand (CBOD) decay rates by the IEPA and traveltime and reaeration-rate coefficients by the U.S. Geological Survey facilitated the development of a model for simulation of water quality in the Salt Creek watershed. In general, the verification of the calibrated model increased confidence in the utility of the model for water-quality planning in the Salt Creek watershed. However, the model was adjusted to better simulate constituent concentrations measured during the June 27-28, 1995, diel survey. Two versions of the QUAL2E model were utilized to simulate dissolved oxygen (DO) concentrations in the Salt Creek watershed for selected effluent discharge and concentration scenarios for water-quality planning: (1) the QUAL2E model calibrated to the August 29-30, 1995, diel survey, and (2) the QUAL2E model adjusted to the June 27-28, 1995, diel survey. The results of these simulations indicated that the QUAL2E model adjusted to the June 27-28, 1995, diel survey simulates reliable information for water-quality planning. The results of these simulations also indicated that to maintain DO concentrations greater than 5 milligrams per liter (mg/L) throughout most of Salt Creek for 7-day, 10-year low-flow conditions, the sewage-treatment plants (STP's) must discharge

    The Qingshui geothermal field is located at the upstream valley of Lanyang Creek, northeastern Taiwan. It is renowned as a geothermal field. The previous studies demonstrated a higher geothermal gradient, 100oC/km warmer than a normal geotherm. However, Qingshui geothermal field has not been well developed due to the higher mining costs. In the recent years, the Taiwan government has been focusing on developing alternative and renewable energy and initiated a 10 year project, Nation Energy Program. This study is part of this project In general, it is very difficult to collect deep downhole samples without considerable change of hydro- and gas- chemistry of water under high temperature and pressure. A new sampling tool, GTF Sampler, was designed by the research team, Green Energy and Environment Laboratories, Industrial Technology Research Institute. This tool can simultaneously collect high quality geothermal water and gas sample and moreover, the sampling depth can reach up to 800 meters. Accordingly, a more accurate measurements can be conducted in the laboratory. In this study, 10 geothermal samples were collected and measured. The results demonstrate that geothermal water samples are characterized with Na(K)-HCO3 water type and located at the mature water area in Giggenbach Na-K-Mg diagram. Several geothermometers, including silica and cation geothermometry, were used to estimate potential temperature in the geothermal reservoir systems. In general, the geothermoters of Na-K and Na-K-Ca obtain reservoir temperatures between 120-190oC and 130-210oC, respectively, but the silica geothermometer indicates a lower reservoir temperature between 90 and 170oC. There is no big difference among them. It is worth to note that all calculated temperatures are lower than those of in-situ downhole measurements; therefore, more detailed and advanced researches would be needed for the inconsistency. To examine the argument about igneous heat source in the previous studies, rare

    structural, gravitational, coastal, alluvial and karst processes were mapped. Particular attention was devoted to the recognition and classification of landslides of different type (in particular block slides and earth flows/slides) which affect large sectors of the north-eastern coast of Gozo. In most cases, landslide accumulations reach the coastline and cover shore platforms. In addition, wide portions of the plateau areas are affected by rock spreading related to the presence of limestones overlying clayey terrains. The climatic conditions, the dense joint systems and the karstification of limestone determine a temporary superficial drainage pattern. Temporary streambeds (wieden in Maltese) were identified in correspondence of V-shaped valleys once occupied by permanent water courses. Karst processes widely affect the Upper Coralline Limestone Formation resulting in caves, diffuse solution pools, grooves and furrows. The geomorphological map output represents a baseline document on which to undertake, first the landslide susceptibility mapping, subsequently the hazard mapping and finally the risk mapping, a critical part of the wider-scoped risk management process of this and similar coastal areas.

    Full Text Available Aim: The aim of this article is to study the satisfaction of patients with laboratory services in outpatient care in Northeastern Bulgaria regarding access and quality of service. Study design: Prospective cohort study Material and methods: The survey was carried out on the territory of Northeastern Bulgaria and covered the districts of Varna, Dobrich and Shumen and thirty municipalities. The following methods were applied in the study: sociological method by applied direct anonymous questionnaire, documentary method and statistical methods for analysis and interpretation of the data in order to reveal the nature of the observed phenomena and their interrelations. Results: The research data show that 24,4% of the respondents live at a distance of more than ten kilometres from the nearest medico-diagnostic laboratory. The larger share of these patients are residents of small settlements in Northeastern Bulgaria. More than half (55% of the respondents are not satisfied with their provision of laboratory services, but the majority of patients claim that the location of the selected laboratory is accessible (69,4% and the quality of the laboratory service is high (83,7%. Conclusion: The main problems in outpatient care are related to the poor provision of medico-laboratory services and specialized outpatient care in the smaller settlements in Northeastern Bulgaria.

    Full Text Available Temperature, nutrients, and salinity are among the important factors constraining the distribution and abundance of microorganisms in the ocean. Marine Group II (MGII belonging to Euryarchaeota commonly dominates the planktonic archaeal community in shallow water and Marine Group I (MGI, now is called Thaumarchaeota in deeper water in global oceans. Results of quantitative PCR (qPCR and 454 sequencing in our study, however, showed the dominance of MGII in planktonic archaea throughout the water column of the northeastern South China Sea (SCS that is characterized by strong water mixing. The abundance of ammonia-oxidizing archaea (AOA representing the main group of Thaumarchaeota in deeper water in the northeastern SCS was significantly lower than in other oceanic regions. Phylogenetic analysis showed that the top operational taxonomic units (OTUs of the MGII occurring predominantly below 200 m depth may be unique in the northeastern SCS based on the observation that they are distantly related to known sequences (identity ranging from 90–94%. The abundance of MGII was also significantly correlated with total bacteria in the whole column, which may indicate that MGII and bacteria may have similar physiological or biochemical properties or responses to environmental variation. This study provides valuable information about the dominance of MGII over AOA in both shallow and deep water in the northeastern SCS and highlights the need for comprehensive studies integrating physical, chemical, and microbial oceanography.

  8. Labor and Employment in Brazilian Northeastern Agriculture: a look at the 2004-2014 period

    Directory of Open Access Journals (Sweden)

    Otavio Valentim Balsadi

    Full Text Available Abstract: The labor market in the Brazilian Northeastern agriculture is characterized by many forms of occupation, ranging from the salaried work to the various forms of family work. In a heterogeneous and diverse agriculture, there is a complex labor market, with changes in recent times. Therefore, it is necessary to keep a watchful eye on important structural features. As a result, this paper aims to analyze the main aspects related to work and employment relations in the Brazilian Northeastern agriculture in the 2004-2014 period. The sources of information are special tabulations from the National Survey by Household Sample (PNAD, conducted by the Brazilian Institute of Geography and Statistics (IBGE. The results pointed to a continuing decline in Northeastern PEA (Economically Active Population occupied in agriculture, partially offset by the growth of Northeastern rural residents occupied in non-agricultural activities, in addition to the people occupied in self-consumption production. Women and young people were the ones who mostly left the agricultural activities, reinforcing the “ageing” process of the occupied PEA. The crops with the largest reduction in the occupied in agricultural PEA were: cassava, rice, coffee, banana, sugarcane, cocoa, vegetables and fruits. On the other hand, the number of occupied people increased in: corn and grape cultivation, services for agriculture, swine and poultry farming and integrated agricultural and livestock production systems. An increase in schooling of the occupied PEA was registered, though it is still below the national average.

    Full Text Available Childhood diarrheal diseases remain highly endemic in northeastern Brazil. The attributable fraction of all diarrheal diseases among children less than 2 years of age due to Escherichia coli was examined in a 2-year prospective study in two large urban centers of Brazil. Between May 1997 and June 1999, fecal E. coli isolates from 237 children with diarrhea (217 acute and 20 persistent cases and 231 children without diarrhea (controls attending two hospitals in Northeast Brazil were tested for their pattern of adherence to HEp-2 cells and for colony hybridization with DNA probes specific for the six pathotypes of diarrheagenic E. coli. Enteroinvasive E. coli, enterotoxigenic E. coli and enterohemorrhagic E. coli were not isolated from any children. Diffusely adherent E. coli (DAEC and enteroaggregative E. coli (EAEC were the most frequent isolates with similar frequencies from children with or without diarrhea. Atypical EPEC (EAF-negative strains were isolated with similiar frequency from both cases (5.5% and controls (5.6%. Enteropathogenic E. coli (typical EPEC strains, characterized by localized adherence pattern of adherence, hybridization with the EAF probe, and belonging to the classical O serogroups, were significantly associated with diarrhea (P = 0.03. These E. coli strains associated with diarrhea accounted for 9% of all children with diarrhea. Collectively, in Northeast Brazil, E. coli strains comprise a small proportion of severe diarrhea prevalence in children.

    Arsenic in drinking water has been shown to increase the risk of urothelial carcinoma and lung cancer. However, the lifetime risk of developing urothelial carcinoma and lung cancer caused by exposure to arsenic in drinking water has not been reported. This study aimed to assess the lifetime risk of urothelial carcinoma and lung cancer caused by arsenic exposure from drinking water and cigarette smoking habit for residents living in the arseniasis-endemic area in Northeastern Taiwan. We recruited 8086 residents in 1991-1994 and monitored them for their newly developed types of cancers, identified by computerized linkage with the national cancer registry profile. There were 37 newly diagnosed urothelial carcinoma cases and 223 new lung cancer cases during the follow-up period (until 2007). The lifetime (35-85 years old) cumulative risk of developing urothelial carcinoma from an arsenic concentration in the drinking water of smoking was associated with an increased risk of urothelial carcinoma and lung cancer, showing the hazard ratio (95% confidence interval) of 2.48 (1.27-4.82) and 3.44 (2.00-5.90) after adjusting for the arsenic concentration in drinking water. After adjusting for cigarette smoking, the hazard ratio (95% confidence interval) of developing urothelial carcinoma caused by the arsenic concentration in drinking water of smoking. It is suggested that people who have had a high exposure to arsenic in drinking water should stop smoking cigarettes to lower their lifetime risk of urothelial carcinoma and lung cancer.

    Outbreaks of cutaneous leishmaniasis are relatively common among soldiers involved in nocturnal activities in tropical forests. We investigated the population dynamics of sand flies in a military training camp located in a remnant of Atlantic rainforest in northeastern Brazil, where outbreaks of cutaneous leishmaniasis have sporadically been described. From July 2012 to July 2014, light traps were monthly placed in 10 collection sites, being nine sites located near the forest edge and one near a sheep and goat stable. Light traps operated from 5:00 pm to 6:00 am, during four consecutive nights. Leishmania infection in sand flies was assessed using a fast real-time PCR assay. Cases of cutaneous leishmaniasis among soldiers were also investigated. In total, 24,606 sand flies belonging to 25 species were identified. Males (n = 12,683) predominated over females (n = 11,923). Sand flies were present during all months, being more numerous in March (n = 1,691) and April 2013 (n = 3,324). Lutzomyia choti (72.9%) was the most abundant species, followed by Lutzomyia longispina (13.8%), Lutzomyia complexa (5.3%), representing together >90% of the sand flies collected. Forty cases of cutaneous leishmaniasis were recorded among soldiers from January 2012 to December 2014. Leishmania isolates were obtained from eight patients and were all characterized as Leishmania braziliensis. Soldiers and anyone overnighting in Atlantic rainforest remnants should adopt preventative measures such as the use of repellents on bare skin or clothes and insecticide-treated tents.

    2010-01-01

    Full Text Available The marine sediment samples collected from the northeastern Brazilian continental shelf, at water depths between 20 and 80 m, consisted mainly of sands with an almost total absence of gravel and granules. Medium, coarse and very coarse sand grains are mostly composed of halimeda, lithothamnium, rodoliths and bioclastic sands with a carbonate content varying between 77 and 96 %. The chemistry in general shows a decreasing content of Ca (86.1 % >Si (6 % > Cl (3.6 % > Sr (0.8 % > K (0.66 % > S (0.62 % > Al (0.6 % > Na (0.55% > Mg (0.43 % > Fe (0.4 % > P (0.2 % > Br (0.04 % in the samples. There was no correlation between CaCO3 and chemical contents and grain size with depth and bio-components. With the exception of Sr of marine origin, all other elements (P, S, Br, Cl, Fe are of continental origin. The lithothamnium of some offshore samples shows higher CaCO3 content, while Mg and Na are present only in halimedas. Bioclastic sands contain no Br, and silt and clay fractions are rare and characterize samples closer to the coast. These marine bioclastic granulates are of very pure biogenic calcium carbonates and are thus highly to be recommended for economic purposes.Os granulados marinhos, da Plataforma Continental do nordeste brasileiro, coletados de profundidades entre 20 e 80 m, são predominantemente areias cascalhosas constituídas de halimedas, litotames, rodolitos e areias bioclásticas, cujos teores de carbonatos variam de 77 a 96 %. A concentração média geral de elementos químicos na ordem decrescente é Ca (86.1 % > Si (6 % > Cl (3.6 % > Sr (0.8 % > K (0.66 % > S (0.62 % > Al (0.6 % > Na (0.55 % > Mg (0.43 % > Fe (0.4 % > P (0.2 % > Br (0,04 %, independentemente da profundidade e tipo de bio-componente.

    Zona Citrícola is an important area for Mexico due to its citriculture activity. Situated in a sub-humid to humid climate adjacent to the Sierra Madre Oriental, this valley hosts an aquifer system that represents sequences of shales, marls, conglomerates, and alluvial deposits. Groundwater flows from mountainous recharge areas to the basin-fill deposits and provides base flows to supply drinking water to the adjacent metropolitan area of Monterrey. Recent studies examining the groundwater quality of the study area urge the mitigation of groundwater pollution. The objective of this study was to characterize the physical and chemical properties of the groundwater and to assess the processes controlling the groundwater's chemistry. Correlation was used to identify associations among various geochemical constituents. Factor analysis was applied to identify the water's chemical characteristics that were responsible for generating most of the variability within the dataset. Hierarchical cluster analysis was employed in combination with a post-hoc analysis of variance to partition the water samples into hydrochemical water groups: recharge waters (Ca-HCO3), transition zone waters (Ca-HCO3-SO4 to Ca-SO4-HCO3) and discharge waters (Ca-SO4). Inverse geochemical models of these groups were developed and constrained using PHREEQC to elucidate the chemical reactions controlling the water's chemistry between an initial (recharge) and final water. The primary reactions contributing to salinity were the following: (1) water-rock interactions, including the weathering of evaporitic rocks and dedolomitization; (2) dissolution of soil gas carbon dioxide; and (3) input from animal/human wastewater and manure in combination with by denitrification processes. Contributions from silicate weathering to salinity ranged from less important to insignificant. The findings suggest that it may not be cost-effective to regulate manure application to mitigate groundwater pollution.

    Leaks in natural gas infrastructure release methane (CH4), a potent greenhouse gas, into the atmosphere. The estimated fugitive emission rate associated with the production phase varies greatly between studies, hindering our understanding of the natural gas energy efficiency. This study presents a new application of inverse methodology for estimating regional fugitive emission rates from natural gas production. Methane observations across the Marcellus region in northeastern Pennsylvania were obtained during a three week flight campaign in May 2015 performed by a team from the National Oceanic and Atmospheric Administration (NOAA) Global Monitoring Division and the University of Michigan. In addition to these data, CH4 observations were obtained from automobile campaigns during various periods from 2013-2015. An inventory of CH4 emissions was then created for various sources in Pennsylvania, including coalmines, enteric fermentation, industry, waste management, and unconventional and conventional wells. As a first-guess emission rate for natural gas activity, a leakage rate equal to 2% of the natural gas production was emitted at the locations of unconventional wells across PA. These emission rates were coupled to the Weather Research and Forecasting model with the chemistry module (WRF-Chem) and atmospheric CH4 concentration fields at 1km resolution were generated. Projected atmospheric enhancements from WRF-Chem were compared to observations, and the emission rate from unconventional wells was adjusted to minimize errors between observations and simulation. We show that the modeled CH4 plume structures match observed plumes downwind of unconventional wells, providing confidence in the methodology. In all cases, the fugitive emission rate was found to be lower than our first guess. In this initial emission configuration, each well has been assigned the same fugitive emission rate, which can potentially impair our ability to match the observed spatial variability

    Venous ulcers account for 70% of chronic leg ulcers and affect about 2-7% of the population, causing much socioeconomic impact and reducing patients' quality of life. In this study we aimed to describe the clinical features of venous ulcers and sociodemographic characteristics of patients with ulcers due to chronic venous disease (CVD). This cross-sectional, observational study was conducted at the Vascular Surgery Service, Universidade Federal de Sergipe, in northeastern Brazil. The study included a consecutive series of 154 patients with active venous ulcers (CEAP C6) in the lower limb due to CVD. Sociodemographic characteristics (age, gender, race, monthly income, education, occupation, and caregiver) and clinical data (affected limb, ulcer site, etiopathogenesis, recurrence, and time elapsed since the first episode of ulcer) were collected. A possible correlation of time elapsed since the first episode of ulcer and number of recurrences with primary or secondary etiology was analyzed by Mann-Whitney U-test. Of the 154 patients analyzed, 79% were female, 94% were ethnically black or brown, 90% had a monthly income less than or equal to minimum wage, 47% were illiterate, 35% had not completed elementary school, 50% had informal jobs, 19.5% were retired, and 18.2% received sick pay from the social security system. The mean age was 53.7 years. Both limbs were affected similarly, and venous ulcers were located predominantly on the medial aspect of the leg (84%). The median time elapsed since the first episode of ulcer was 36 months, being significantly higher in patients with venous ulcers of secondary etiology (P < 0.0003). The prevalence of recurrence was also significantly higher in patients with venous ulcers of secondary etiology (P < 0.001). According to CEAP classification, 65% of ulcers were primary (Ep), 94.1% demonstrated reflux involving the superficial system (As), 92% had incompetent perforators (Ap), 35% demonstrated reflux involving the deep system

    Home births are common in resource poor countries and postnatal practices vary from one community to the other. To determine the proportion of home births, reasons for home delivery, and evaluate postnatal practices in Madagali, north-eastern Nigeria. This was a cross-sectional descriptive study of 400 women of reproductive age, who had put to birth in the past 1 year. The study was carried out over a period of 8 weeks from April to June 2010. The multistage method of sampling was used to select respondents. In the first stage, four of the five health districts were chosen randomly, namely, Gulak, Madagali, Sukur, and Duhu. The questionnaires were evenly distributed among the four health districts. In the second stage, from each district, two villages were chosen by simple random sample. In the third stage, two wards were selected in each village by simple random sampling. Of the 400 respondents interviewed, 289 (72.2%) were aged between 20 and 39 years, and most, 374 (93.5%) were married. Only 14 (3.5%) had tertiary education. Most respondents, 224 (56.0%) were farmers and grandmultiparae, 187 (46.7%). A total of 196 (49.0%) women delivered at home, whereas 204 (51.0%) delivered at the hospital. Of the 196 respondents who delivered at home, the bedroom 142 (72.4%), was the preferred place of birth. The most common reason for home birth was short duration of labor in 71 (36.3%) cases. Delivery was conducted by untrained persons in 50, (25.4%), whereas 99 (50.8%) and 31 (15.5%) deliveries were supervised by Traditional Birth Attendants (TBAs) and Midwives/Nurses, respectively. Postpartum, the majority, 235 (58.7%) respondents used sanitary pads to stanch lochia, whereas 140 (35%) used rags. A significant number of births take place in the home and supervised by unskilled persons. Against the backdrop of poor education and low socio-economic status of respondents, perineal hygiene can be adjudged satisfactory. There is the need to increase on the number of hospital

  1. Contribution of Nutrient Pollution to Water Scarcity in the Water-Rich Northeastern United States

    Most studies of water stress focus on water-scarce regions such as drylands. Yet, even water-rich regions can be water stressed due to local water withdrawals that exceed supply or due to water pollution that makes water unusable. The northeastern United States (NE) is a water-rich region relative to the rest of the country, as it concentrates about 50% of total renewable water of the country. Yes the NE features relatively high water withdrawals, ~50 km3/yr, for thermo-power generation, agriculture, and industry, as well as to support a human population of about 70 million. At the same time, rivers and streams in the NE suffer from nutrient pollution, largely from agricultural and urban land uses. We asked: to what extent is the NE water stressed, and how do water withdrawals and water quality each contribute to water scarcity across the NE? We used information on county-level water withdrawals and runoff to calculate a water scarcity index (WSI) for 200 hydrologic units across the NE from 1987 to 2002. We used data on surface water concentrations of nitrogen to calculate the additional water necessary to dilute surface water pollution to weak, moderate, and strong water quality standards derived from the literature. Only considering withdrawals, we found that approximately 10% of the NE was water stressed. Incorporating a moderate water quality standard, 25% of the NE was water stressed. We calculated a dilution burden by sectors of water users and found that public utilities faced 41% of the total dilution burden for the region, followed by irrigation users at 21%. Our results illustrate that even water rich regions can experience water stress and even scarcity, where withdrawals exceed surface water supplies. Water quality contributes to water stress and can change the spatial patterns of water stress across a region. The common approach to address scarcity has required the use of inter-basin water transfers, or in the case of water quality-caused scarcity

    Predictive tools and a large new dataset for the northeastern Chukchi Sea (NECS) are used here to help identify regional differences and potential future shifts in the magnitude of Hg biomagnification in the Arctic. At the base of the food web in the NECS, concentrations of total mercury (THg) in phytoplankton (20-μm mesh) ranged from 4-42 ng g-1 dry weight, partly in response to variations in algal biomass and water temperature. A >3-fold increase in monomethylmercury (MMHg) was observed in zooplankton (4.3±0.7 ng g-1) relative to phytoplankton (150-fold and from 85%, respectively, from phytoplankton to muscle in the whelk Plicifusus kroeyeri (279 ng g-1, TL 4.5). For muscle tissue in 10 species plus whole phytoplankton and zooplankton, the trophic magnification slope (TMS) for MMHg (log10[MMHg]=m(δ15N)+b; where m=TMS) was 0.23±0.02 (SE). No significant differences in TMS were found for the NECS plus three other studies from the eastern Canadian Arctic (average TMS=0.24±0.02). Nevertheless, all data for MMHg in biota from the NECS plotted below the combined best fit line for all four studies. Results from an ANCOVA showed that statistically different (p=0.001) intercept values (b), not TMS, best explained the >2-fold lower concentrations of MMHg in biota from the NECS (b=-1.85) relative to the same species from the eastern Canadian Arctic (b=-1.29). Future changes that affect bioaccumulation of MMHg in the Arctic may impact the biomagnification equation by shifting the TMS, intercept or both. The intercept is more likely to respond to changes in productivity and concentrations of dissolved Hg whereas the TMS may respond to changing growth rates due to fluctuations in productivity and food availability. In either case, small changes in the intercept or TMS coincide with predictably large increases or decreases in MMHg concentrations in apex predators.

    In late 2005 and early 2006, the WTW Operating, LLC (W.T.W. Oil Co., Inc.) no. 1 Wilson well (T.D. = 5772 ft; 1759.3 m) was drilled for 1826 ft (556.6 m) into Precambrian basement underlying the Forest City Basin in northeastern Kansas. Approximately 4500 of the 380,000 wells drilled in Kansas penetrate Precambrian basement. Except for two previous wells drilled into the arkoses and basalts of the 1.1-Ga Midcontinent Rift and another well drilled in 1929 in basement on the Nemaha Uplift east of the Midcontinent Rift, this well represents the deepest penetration into basement rocks in the state to date. Granite is the typical lithology observed in wells that penetrate the Precambrian in the northern Midcontinent. Although no cores were taken to definitively identify lithologies, well cuttings and petrophysical logs indicate that this well encountered basement metamorphic rocks consisting of schist, gneiss, and amphibolitic gneiss, all cut by aplite dikes.The well was cased and perforated in the Precambrian, and then acidized. After several days of swabbing operations, the well produced shows of low-Btu gas, dominated by the non-flammable component gases of nitrogen (20%), carbon dioxide (43%), and helium (1%). Combustible components include methane (26%), hydrogen (10%), and higher molecular-weight hydrocarbons (1%). Although Coveney and others [Am. Assoc. Petroleum Geologists Bull., v. 71, no, 1, p. 39-48, 1987] identified H 2 -rich gas in two wells located close to the Midcontinent Rift in eastern Kansas, this study indicates that high levels of H 2 may be a more widespread phenomenon than previously thought. Unlike previous results, the gases in this study have a significant component of hydrocarbon gas, as well as H 2 , N 2 , and CO 2 . Although redox reactions between iron-bearing minerals and groundwater are a possible source of H 2 in the Precambrian basement rocks, the hydrocarbon gas does not exhibit the characteristics typically associated with proposed

    The achievement of the Officially Tuberculosis Free (OTF) status in regions with low bovine Tuberculosis (bTB) herd prevalence, as is the case of North-Eastern Spain (Catalonia), might be a likely option in the medium term. In this context, risk-based approaches could be an alternative surveillance strategy to the costly current strategy. However, before any change in the system may be contemplated, a reliable estimate of the sensitivity of the different surveillance components is needed. In this study, we focused on the slaughterhouse component. The probability of detection of a bTB-infected cattle by the slaughterhouses in Catalonia was estimated as the product of three consecutive probabilities: (P1) the probability that a bTB-infected animal arrived at the slaughterhouse presenting Macroscopically Detectable Lesions (MDL); (P2) the probability that MDL were detected by the routine meat inspection process and (P3) the probability that the veterinary officer suspected bTB and sent the sample for laboratory confirmation. The first probability was obtained from data collected through the bTB eradication program carried out in Catalonia between 2005 and 2008, while the last two were obtained through the expert opinion of the veterinary officers working at the slaughterhouses who fulfilled a questionnaire administered during 2014. The bTB surveillance sensitivity of the different cattle slaughterhouses in Catalonia obtained in this study was 31.4% (CI 95%: 28.6-36.2), and there were important differences among them. The low bTB surveillance sensitivity was mainly related with the low probability that a bTB-infected animal arrived at the slaughterhouse presenting MDL (around 44.8%). The variability of the sensitivity among the different slaughterhouses could be explained by significant associations between some variables included in the survey and P2. For instance, factors like attendance to training courses, number of meat technicians and speed of the slaughter chain

    The Fulong-beach dune field is located at the north-eastern coast of Taiwan. Built up of medium and fine grained quartz rich sand, it represents a unique feature of only few kilometres along the east coast of Taiwan. This unique sedimentological regime makes the area most perfectly suitable for age estimations by optically stimulated luminescence (OSL). The dune field is crossed by the Shuangsi-river, which flows into the Pacific Ocean. The coastal area is subjected to very dynamic conditions in the transition zone between land and sea. Due to the constant force of marine and aeolian processes from tides, weather and sediment accumulation by rivers, it is a continuously changing area. Taiwan is located in a very active tectonic zone with high elevation rates, which reach from 4 mm per year at the east coast up to 7 mm per year in the southern parts of the island. Furthermore Taiwan is affected by medial 3.8 typhoons per year and minor earthquakes nearly occur every day (LIN ET AL. 2006). The consequences are high rates of erosion and sediment transport during very short time periods. The Fulong-beach coastal area is densely populated and proud for being a tourism destination. At the northern end of the dune field the Lungmen nuclear power plant is currently under construction. Four separate dune ridges could be identified from a digital elevation model and from field mapping. During the field campaign in October and November 2009 17 samples were taken for OSL-dating (MURRAY ET AL. 1995) out of the four dune ridges as well as out of a more than 30 m high elevated outcrop cut by the Shuangsi-river. The measurement and the evaluation of the OSL-samples will provide us an insight into the duration and intensity of the processes affecting the coastal area of Taiwan during the Holocene. We will give an outline during the poster presentation of the methodical approach and the morphodynamical processes affecting the Fulong-beach dune field in north-eastern Taiwan

    Submicron aerosol particles (PM1) remain a major air pollution concern in the urban areas of northeastern U.S. While SO2 and NOx emission controls have been effective at reducing summertime PM1 concentrations, this has not been the case for wintertime sulfate and nitrate concentrations, suggesting a nonlinear response during winter. During winter, organic aerosol (OA) is also an important contributor to PM1 mass despite low biogenic emissions, suggesting the presence of important urban sources. We use aircraft-based observations collected during the Wintertime INvestigation of Transport, Emissions and Reactivity (WINTER) campaign (Feb-March 2015), together with the GEOS-Chem chemical transport model, to investigate the sources and chemical processes governing wintertime PM1 over the northeastern U.S. The mean observed concentration of PM1 between the surface and 1 km was 4 μg m-3, about 30% of which was composed of sulfate, 20% nitrate, 10% ammonium, and 40% OA. The model reproduces the observed sulfate, nitrate and ammonium concentrations after updates to HNO3 production and loss, SO2 oxidation, and NH3 emissions. We find that 65% of the sulfate formation occurs in the aqueous phase, and 55% of nitrate formation through N2O5 hydrolysis, highlighting the importance of multiphase and heterogeneous processes during winter. Aqueous-phase sulfate production and the gas-particle partitioning of nitrate and ammonium are affected by atmospheric acidity, which in turn depends on the concentration of these species. We examine these couplings with GEOS-Chem, and assess the response of wintertime PM1 concentrations to further emission reductions based on the U.S. EPA projections for the year 2023. For OA, we find that the standard GEOS-Chem simulation underestimates the observed concentrations, but a simple parameterization developed from previous summer field campaigns is able to reproduce the observations and the contribution of primary and secondary OA. We find that

    Full Text Available Background: Although many studies had been conducted on various aspects of canine visceral leishmaniasis (CVL in domestic dogs in the endemic areas of Iran, investigations on CVL in wild canines are rare.Methods: This is a cross-sectional study was conducted from December 2012 to 2013 in northeast of Iran where human VL is endemic. Wild canines were trapped around the areas where human VL cases had been previously identified. Wild canines were collected and examined both clinically and serologically using direct agglutination test (DAT. Microscopically examinations were performed in all the seropositive wild canines for the presence of the amastigote form of Leishmania spp. Some Leishmania sp. which had been isolated from the spleens of wild canines, were examined analyzed by conventional PCR and sequencing techniques using α-tubulin and GAPDH genes.Results: Altogether, 84 wild canines including foxes (Vulpes vulpes, n=21, Jackals (Canis aureus, n=60 and wolves (Canis lupus, n=3 were collected. Four foxes and seven jackals showed anti-Leishmania infantum antibodies with titers of 1:320–1:20480 in DAT. Furthermore, one fox and one jackal were parasitologically (microscopy and culture positive and L. infantum was confirmed by sequence analysis.Conclusion: The present study showed that sylvatic cycle of L. infantum had been established in the studied endemic areas of VL in northeastern Iran.

    Calc-alkalic to high-K calc-alkalic granitoid plutons in the Borborema province, northeastern Brazil, have been studied to constrain depth of emplacement by mineralogical and geological methods and to estimate upward magma transport rate based on partial dissolution of magmatic epidote. Laser-probe incremental heating 40Ar/ 39Ar dating of biotite and hornblende single crystals from the Neoproterozoic Tavares and Brejinho high-K calc-alkalic magmatic epidote (mEp)-bearing plutons reveals age differences of around 60 M.y. between these two minerals in each of these two intrusions. These data suggest solidification at relatively great depth followed by prolonged cooling interval between the closure temperatures of biotite and hornblende. Al-in-hornblende barometry indicates that hornblende in several mEp-bearing plutons in the Transversal Domain of the Borborema province solidified at 5 to 7 kbar, whereas in the Seridó and Macururé terranes, solidification pressures range from 3 to 4 kbar. Partial dissolution of epidote indicates very rapid upward transport. Partial corrosion occurred during 15-35 years (Cachoerinha-Salgueiro terrane), 10-30 years (Alto Pajeú), 15 years (Seridó), and 10 years (Macururé) corresponding to upward transport rates of 450-1300, 650-1050, 1200, and 1800 m/year respectively in these four terranes. Rapid upward magma migration in most cases was probably facilitated by diking simultaneous with regional shearing.

    This study aimed to analyse changes in the spatial distribution of Lutzomyia longipalpis in Posadas, an urban area located in northeastern Argentina. Data were obtained during the summer of 2007 and 2009 through two entomological surveys of peridomiciles distributed around the city. The abundance distribution pattern for 2009 was computed and compared with the previous pattern obtained in 2007, when the first human visceral leishmaniasis cases were reported in the city. Vector abundance was also examined in relation to micro and macrohabitat characteristics. In 2007 and 2009, Lu. longipalpis was distributed among 41.5% and 31% of the households in the study area, respectively. In both years, the abundance rates at most of the trapping sites were below 30 Lu. longipalpis per trap per night; however, for areas exhibiting 30-60 Lu. longipalpis and more than 60 Lu. longipalpis, the areas increased in both size and number from 2007-2009. Lu. longipalpis was more abundant in areas with a higher tree and bush cover (a macrohabitat characteristic) and in peridomiciles with accumulated unused material (a microhabitat characteristic). These results will help to prioritise and focus control efforts by defining which peridomiciles display a potentially high abundance of Lu. longipalpis. PMID:24271040

    Q fever is a worldwide zoonotic disease caused by Coxiella burnetii (C. burnetii), an obligate intracellular bacterium. In ruminants, shedding into the environment mainly occurs during parturition or abortion, but the bacterium is shed also in milk, vaginal mucus, stools and urine. In Italy few surveys have been conducted and reported seroprevalence values ranged between 10% and 60%, even if few human cases have been described. Genotyping of bacteria is crucial for enhancing diagnostic methods and for epidemiological surveillance. The objective of this study was to investigate genotypic differences of C. burnetii genotypes directly in 34 samples, collected during a 3-years survey among 11 dairy cattle and 11 goat farms in the north-eastern part of Italy using a 6-locus multiple loci variable number of tandem repeat analysis (MLVA) method. The samples analysed included 13 bulk tank milk (BTM), 6 individual milk, 11 vaginal swabs and 4 foetal spleens. MLVA-type 2 was determined as the most prevalent in cattle in this study. C. burnetii strains circulating in the studied cattle population are very similar to genotypes previously described, while genotypes from goats showed an important variability. Further investigation are needed to understand the reason of this pattern. Copyright © 2015 Institut Pasteur. Published by Elsevier Masson SAS. All rights reserved.

    The detection of live Mycobacterium leprae in soil and animals other than humans suggests that the environment plays a role in the transmission of leprosy. The objective of this study was to investigate the presence of viable M. leprae in natural water sources used by the local population in five municipalities in the state of Ceará, northeastern Brazil. Samples were collected from 30 different sources. Viable bacilli were identified by reverse transcriptase polymerase chain reaction (PCR) of the M. leprae gyrA gene and sequencing of the PCR products. Physicochemical properties of each water source were also assessed. M. leprae gyrA mRNA was found in 23 (76.7%) of the water sources. No association was found between depth of the water and sample positivity, nor was there any association between the type of water used by the population and sample positivity. An association between viable M. leprae and temperature and pH was found. Georeferencing showed a relation between the residences of leprosy cases and water source containing the bacterium. The finding of viable M. leprae in natural water sources associated with human contact suggests that the environment plays an important role in maintaining endemic leprosy in the study region.

    Full Text Available This study aimed to analyse changes in the spatial distribution of Lutzomyia longipalpis in Posadas, an urban area located in northeastern Argentina. Data were obtained during the summer of 2007 and 2009 through two entomological surveys of peridomiciles distributed around the city. The abundance distribution pattern for 2009 was computed and compared with the previous pattern obtained in 2007, when the first human visceral leishmaniasis cases were reported in the city. Vector abundance was also examined in relation to micro and macrohabitat characteristics. In 2007 and 2009, Lu. longipalpis was distributed among 41.5% and 31% of the households in the study area, respectively. In both years, the abundance rates at most of the trapping sites were below 30 Lu. longipalpis per trap per night; however, for areas exhibiting 30-60 Lu. longipalpis and more than 60 Lu. longipalpis, the areas increased in both size and number from 2007-2009. Lu. longipalpis was more abundant in areas with a higher tree and bush cover (a macrohabitat characteristic and in peridomiciles with accumulated unused material (a microhabitat characteristic. These results will help to prioritise and focus control efforts by defining which peridomiciles display a potentially high abundance of Lu. longipalpis.

  18. Possible Role of Hadley Circulation Strengthening in Interdecadal Intensification of Snowfalls Over Northeastern China Under Climate Change

    Zhou, Botao; Wang, Zunya; Shi, Ying

    This article revealed that strengthening of winter Hadley circulation in the context of climate change may partially contribute to interdecadal increasing of snowfall intensity over northeastern China in recent decades. This hypothesis is well supported by the process-based linkage between Hadley circulation and atmospheric circulations over the Asian-Pacific region on the interdecadal time scale. The strengthening of winter Hadley circulation corresponds to a weakening of the Siberian high, an eastward shifting of the Aleutian low, a reduction of the East Asian trough, and anomalous southwesterly prevailing over northeastern China. These atmospheric situations weaken the East Asian winter monsoon and lead to an increase of air temperature over northeastern China. Increased local evaporation due to the increase of air temperature, concurrent with more water vapor transported from the Pacific Ocean, can significantly enhance atmospheric water vapor content in the target region. Meanwhile, the ascending of airflows is also strengthened over northeastern China. All of these provide favorable interdecadal backgrounds for the occurrence of intense snowfalls, and thus, snowfall intensity is intensified over northeastern China after the 1980s. Further analysis suggests that the circum-Pacific-like teleconnection pattern may play an important role in connecting Hadley circulation strengthening signal and atmospheric circulation anomalies favoring interdecadal intensification of snowfalls over northeastern China.

    Northeastern British Columbia (BC) is undergoing rapid development for oil and gas extraction, largely depending on subsurface hydraulic fracturing (fracking), which relies on available freshwater. Even though this industrial activity has made substantial contributions to regional and provincial economies, it is important to ensure that sufficient and sustainable water supplies are available for all those dependent on the resource, including ecological systems. Further, BC statistics predict that the northeastern region's population will increase by 30% over the next 25 years, thereby amplifying the demands of domestic and industrial water usage. Hence, given the increasing demands for surface water in the complex wetlands of northeastern BC, obtaining accurate long-term water balance information is of vital importance. Thus, this study aims to simulate the 1979-2014 water balance at two boreal watersheds using the MIKE SHE model. More specifically, this research intends to quantify the historical, and regional, water budgets and their associated hydrological processes at two boreal watersheds—the Coles Lake and Tsea Lake watersheds—in northeastern BC. The development of coupled groundwater and surface water model of these watersheds are discussed. The model setup, calibration process, and results are presented, focusing on the water balance of boreal watersheds. Hydrological components within these watersheds are quantified through a combination of intensive fieldwork, observational data, analysis and numerical modeling. The output from the model provides important information for decision makers to manage water resources in northeastern BC. Keywords: Northeastern BC; boreal watershed; water balance; MIKE SHE hydrological model.

    This study demonstrates the importance of accurate extreme discharge input in hydrological and oceanographic combined modeling by introducing two extreme typhoon events. We investigated the effects of extreme freshwater outflow events from river mouths on sea surface salinity distribution (SSS) in the coastal zone of the north-eastern Japan. Previous studies have used observed discharge at the river mouth, as well as seasonally averaged inter-annual, annual, monthly or daily simulated data. Here, we reproduced the hourly peak discharge during two typhoon events for a targeted set of nine rivers and compared their impact on SSS in the coastal zone based on observed, climatological and simulated freshwater outflows in conjunction with verification of the results using satellite remote-sensing data. We created a set of hourly simulated freshwater outflow data from nine first-class Japanese river basins flowing to the western Pacific Ocean for the two targeted typhoon events (Chataan and Roke) and used it with the integrated hydrological (CDRMV3.1.1) and oceanographic (JCOPE-T) model, to compare the case using climatological mean monthly discharges as freshwater input from rivers with the case using our hydrological model simulated discharges. By using the CDRMV model optimized with the SCE-UA method, we successfully reproduced hindcasts for peak discharges of extreme typhoon events at the river mouths and could consider multiple river basin locations. Modeled SSS results were verified by comparison with Chlorophyll-a distribution, observed by satellite remote sensing. The projection of SSS in the coastal zone became more realistic than without including extreme freshwater outflow. These results suggest that our hydrological models with optimized model parameters calibrated to the Typhoon Roke and Chataan cases can be successfully used to predict runoff values from other extreme precipitation events with similar physical characteristics.

    We present evidence of increasing persistence in daily precipitation in the northeastern United States that suggests that global circulation changes are affecting regional precipitation patterns. Meteorological data from 222 stations in 10 northeastern states are analyzed using Markov chain parameter estimates to demonstrate that a significant mode of precipitation variability is the persistence of precipitation events. We find that the largest region-wide trend in wet persistence (i.e., the probability of precipitation in 1 day and given precipitation in the preceding day) occurs in June (+0.9% probability per decade over all stations). We also find that the study region is experiencing an increase in the magnitude of high-intensity precipitation events. The largest increases in the 95th percentile of daily precipitation occurred in April with a trend of +0.7 mm/d/decade. We discuss the implications of the observed precipitation signals for watershed hydrology and flood risk.

    Ngari, Bunyamwera, Ilesha, and Germiston viruses are among the mosquito-borne human pathogens in the Orthobunyavirus genus, family Bunyaviridae, associated with febrile illness. Although the four orthobunyaviruses have been isolated from mosquito and/or tick vectors sampled from different geographic regions in Kenya, little is known of human exposure in such areas. We conducted a serologic investigation to determine whether orthobunyaviruses commonly infect humans in Kenya. Orthobunyavirus-specific antibodies were detected by plaque reduction neutralization tests in 89 (25.8%) of 345 persons tested. Multivariable analysis revealed age and residence in northeastern Kenya as risk factors. Implementation of acute febrile illness surveillance in northeastern Kenya will help to detect such infections.

    Analysis of spatial and temporal variations of sulfur dioxide concentration in planetary boundary layer were conducted. The data were generated by NASA satellite daily from October of 2004 and were obtained through NASA Giovanni. The global monthly mean spatial distribution of sulfur dioxide showed several hot spots including: several spots on some islands in the Pacific Ocean, several spots in central America, and central Africa. Most of these hot spots of sulfur dioxide are related to known active volcanos. The biggest hot spot of sulfur dioxide were observed in Northeastern China. While high concentration sulfur dioxide was still observed in Northeastern China in 2017. The area averaged concentration of sulfur dioxide declined dramatically since its peak in 2008. This temporal trend indicates that sulfur reduction effort has been effective in the last decade or post 2008 financial crisis recovery lead an industry less sulfur dioxide emission.

    Cancer is the second leading cause of death among Native Americans, who have-some of the poorest cancer survival rates of any race/ethnicity nationwide. Considering the cancer burden experienced by Native Americans and the lack of research exploring Northeastern tribal communities' cancer experiences, a qualitative investigation of Native Americans' cancer coping strategies and health education needs was undertaken. Data were collected through group (74) and individual (17) interviews with 91 Native Americans from the Northeast. Relationships between intergenerational mistrust, individual mistrust, and utilization of biomedical health care systems for Northeastern Native Americans are presented. Trust is central to the provider-patient relationship and the foundation for developing and maintaining connections to Native American communities. Intergenerational mistrust, shaped by historical and contemporary issues of prejudice and miscommunication, affect cancer health experiences and views. Approaches for reducing mistrust and building relationships between health care providers and Native communities are highlighted.

    Full Text Available Expanding grain sorghum [Sorghum bicolor (L. Moench] production northward from southeastern Colorado is thought to be limited by shorter growing seasons due to lower temperatures and earlier frost dates. This study used a simulation model for predicting crop phenology (PhenologyMMS to estimate the probability of reaching physiological maturity before the first fall frost for a variety of agronomic practices in northeastern Colorado. Physiological maturity for seven planting dates (1 May to 12 June, four seedbed moisture conditions affecting seedling emergence (from Optimum to Planted in Dust, and three maturity classes (Early, Medium, and Late were simulated using historical weather data from nine locations for both irrigated and dryland phenological parameters. The probability of reaching maturity before the first frost was slightly higher under dryland conditions, decreased as latitude, longitude, and elevation increased, planting date was delayed, and for later maturity classes. The results provide producers with estimates of the reliability of growing grain sorghum in northeastern Colorado.

    Describe community nurses' experiences regarding the meaning and promotion of healthy aging in northeastern Thailand. Data were collected through five focus group interviews with 36 community nurses in northeastern Thailand. Latent content analysis was conducted to analyze the data. Healthy aging was characterized by the interconnection of older persons, older persons' family members, and the community. Healthy aging was associated with two themes: "being strong" and "being a supporter and feeling supported." The nurses' experiences in promoting healthy aging were described by the themes "providing health assessment," "sharing knowledge," and "having limited resources." The findings of this study provide a deeper understanding of the meaning of healthy aging from a holistic viewpoint. Community nurses must pay attention to older persons and their surroundings when planning how to promote healthy aging. Person-centeredness should be applied in practice to promote healthy aging. The current findings contribute useful information that should help policy makers develop healthy aging strategies in Thailand.

    The extent of radioactive disequilibrium between 234 Th- 238 U, 210 Po- 210 Pb and 210 Pb- 226 Ra has been measured in four vertical profiles from the northeastern Arabian Sea, a region characterized by oxygen deficient and denitrification layers at intermediate depths. The most common feature of the data is that the dissolved concentrations of the daughter nuclides are considerably less than those of their parents, exceptions being the near equilibrium or excess concentrations of 210 Po (relative to 210 Pb) at ∼ 100 m and that of 210 Pb relative to 226 Ra in surface waters. These results suggest that scavenging of dissolved 234 Th, 210 Po and 210 Pb occurs throughout the water column in the northeastern Arabian Sea. (Author)

    The deepening of mixed layer and ensuing changes in optical and physicochemical properties of euphotic zone can influence phytoplankton community dynamics in the northeastern Arabian Sea during winter monsoon. The response of picophytoplankton community to such changes during winter convective mixing is not well understood. Herein, we have compared variations in the picophytoplankton community structure during early (November-December 2012), peak (end-January 2014) and late (mid-February 2015) winter monsoon from three separate cruises in the southern northeastern Arabian Sea. The higher Synechococcus abundance owing to entrainment of nutrients in mixed layer was observed during peak winter monsoon, while the concomitant changes in nitrate concentration, light and oxygen environment restricted Prochlorococcus growth resulting in lower abundance during the same period. This highlights the diverse responses of picophytoplankton groups to physicochemical changes of water column during winter convective mixing. The divinyl chlorophyll b/a ratio (marker for Prochlorococcus ecotypes) indicated prevalence of one low-light adapted ecotype (sensitive to light shock) in sub-surface water, one high-light adapted ecotype in surface water during early winter monsoon and both disappeared during intense mixing period in peak winter monsoon. Subsequently, a distinct low-light adapted ecotype, capable to tolerate light shock, was noticed during late winter monsoon and we argue that this ecotype is introduced to southern northeastern Arabian Sea through advection from north by sub-surface circulation. The total picophytoplankton biomass available to microbial loop is restored during late winter monsoon, when stratification begins, with a higher abundance of Synechococcus and the re-occurrence of Prochlorococcus population in the region. These inferences indicate that variability in picophytoplankton community structure and their contribution to the microbial loop are driven by

    An extensive set of volatile organic compounds (VOCs) was measured at the Boulder Atmospheric Observatory (BAO) in winter 2011 in order to investigate the composition and influence of VOC emissions from oil and natural gas (O&NG) operations in northeastern Colorado. BAO is 30 km north of Denver and is in the southwestern section of Wattenberg Field, one of Colorado's most productive O&NG fields. We compare VOC concentrations at BAO to those of other U.S. cities and summertime measurements at two additional sites in northeastern Colorado, as well as the composition of raw natural gas from Wattenberg Field. These comparisons show that (i) the VOC source signature associated with O&NG operations can be clearly differentiated from urban sources dominated by vehicular exhaust, and (ii) VOCs emitted from O&NG operations are evident at all three measurement sites in northeastern Colorado. At BAO, the reactivity of VOCs with the hydroxyl radical (OH) was dominated by C(2)-C(6) alkanes due to their remarkably large abundances (e.g., mean propane = 27.2 ppbv). Through statistical regression analysis, we estimate that on average 55 ± 18% of the VOC-OH reactivity was attributable to emissions from O&NG operations indicating that these emissions are a significant source of ozone precursors.

    Full Text Available The rhomboid fossa of clavicle is used to determine the age and sex in anthropology and forensic sciences. The variant types of rhomboid fossa on inferior surface have been reported in many races except in Thais. This study therefore was aimed at classifying the types of the rhomboid fossa in Northeastern Thais. The identified 476 Northeastern Thais dried clavicles (270 males and 206 females were observed and recorded for the types of rhomboid fossa. The results showed that Thai-rhomboid fossa could be classified into 4 types: Type 1: smooth; Type 2: flat; Type 3: elevated; and Type 4: depressed, respectively. The incidences of rhomboid fossa were as follows: Type 1: 0.21%; Type 2: 19.75%; Type 3: 76.26%; and Type 4: 3.78%, respectively. Additionally, it was found that the percentage of Type 4 (11.84% was much greater than that of female (1.94% compared to other types. This incidence of rhomboid fossa types especially Type 4 may be a basic knowledge to be used in sex identification. The high incidence of rhomboid fossa in both sexes of Northeastern Thai clavicles was Type 3 (elevated type.

    Over the last century, the northeastern United States has warmed by over 1C, with the region of strongest warming found in coastal Massachusetts, Connecticut, and Rhode Island. These states are amongst the fastest warming in the entire country and the region as a whole is also warming faster than the national average. While these records all appear exceptional in the context of the last century, it is not known how these compare on longer time scales, to potential preindustrial late Holocene warm epochs, and in the context of decadal-scale variability in regional climate. Here, we develop a January through August temperature reconstruction using three Chamaecyparis thyoides (Atlantic White Cedar) chronologies in Massachusetts and Maine. The chronologies show a strong winter-spring-summer temperature signal representative of temperature variability from southern New York to northeastern Maine. The reconstruction is skillful and tracks upwards temperature trends since the early 19th century, reproducing decadal scale variability associated with warming from the 1920s through 1940s, cooling in the region from the 1940s until the 1960s, and warming since that time. No year since at least the middle of the 19th century is as warm as the Janaury through August temperatures seen in the exceptionally warm 2012. Recent modeling experiments simulate a range of decadal warming trends for the northeastern United States that is slightly higher than the reconstructed and instrumental trends. Atlantic White Cedar holds the potential to develop multicentury temperature reconstructions from this heavily-populated region.

    The present study was performed to investigate the seroprevalence and risk factors for Dirofilaria immitis infection in cats from Liaoning province, northeastern China. From October 2014 to September 2016, sera of 651 cats, including 364 domestic cats and 287 feral cats (332 females and 319 males) were assessed. They were tested for the presence of D. immitis antigen using SNAP Heartworm RT test kit. In this population, the average prevalence was 4.5%. Age and rearing conditions (feral or domestic) were found to be associated with the prevalence of D. immitis. The prevalence was significantly higher in feral cats compared with domestic cats (8.4% vs 1.4%, P0.05), but older cats (≥3 years old) showed a statistically higher prevalence compared with younger cats (cats (2.4% vs 0.51%, P>0.05), all these results suggest that outdoor exposure time may be one of the most important factors for D. immitis prevalence in cats. Results reveal that D. immitis are prevalence in domestic and feral cats in northeastern China, which indicates that appropriate preventive measures should be taken to decrease the incidence of feline heartworm disease in Liaoning province, northeastern China.

Nine hotels were selected from four provinces in North-eastern Thailand as the research population and the research sample was composed of 86 individuals. Tools used for data collection were survey, observation, interview, focus group discussion and workshop. Results show that hoteliers in North-eastern Thailand developed their businesses as a reaction to the economic crisis and failing trade. To attract more tourists to the region, hotel managers integrated traditional Thai art to their businesses, especially local Isan art. This investigation of nine hotels in Isan identified nine areas in which art has been integrated into hotel businesses. These are paintings, sculptures, architecture, literature, music and dance , the four Buddhist necessities of life (food, accommodation, clothing and medicine, beliefs, customs and ceremonies. By integrating elements of each of these categories into their hotels, business owners and managers have been able to generate extra trade.

    Several literatures have shown the influence of geographic and linguistic factors in shaping genetic variation patterns, but their relative impact, if any, in the very heterogeneous northeastern region of Thailand has not yet been studied. This area, called Isan, is geographically structured in two wide basins, the Sakon Nakorn Basin and the Korat Basin, serving today as home to diverse ethnicities encompassing two different linguistic families, that is, the Austro-Asiatic; Suay (Kui), Mon, Chaobon (Nyahkur), So and Khmer, and the Tai-Kadai; Saek, Nyaw, Phu Tai, Kaleung and Lao Isan. In this study, we evaluated the relative role of geographic distance and barriers as well as linguistic differences as possible causes affecting the maternal genetic distances among northeastern Thai ethnicities. A 596-bp segment of the hypervariable region I mitochondrial DNA was utilized to elucidate the genetic structure and biological affinity from 433 individuals. Different statistical analyses agreed in suggesting that most ethnic groups in the Sakon Nakorn Basin are closely related. Mantel test revealed that genetic distances were highly associated to geographic (r = 0.445, P0.01) distances. Three evolutionary models were compared by Approximate Bayesian Computation. The posterior probability of the scenario, which assumed an initial population divergence possibly related to reduced gene flow among basins, was equal or higher than 0.87. All analyses exhibited concordant results supporting that geography was the most relevant factor in determining the maternal genetic structure of northeastern Thai populations.

    Full Text Available This thoroughly researched and carefully constructed monograph focuses on what is now north-eastern India, an irregularly-shaped region joined only by a narrow neck of land to the remainder of the Indian subcontinent and jostled (or nestled, depending on one's point of view between Bangladesh, Bhutan, Myanmar, Nepal, and Tibet. Crucially, author Gunnel Cederlöf argues, this representation of northeast India on modern maps - an island in constant danger of drifting away from mainland India, held in place only by the "Chicken's Neck" or Siliguri Corridor - bears no relation to the way in which this region was imagined by the British East India Company (EIC in the late eighteenth and early nineteenth centuries. Having obtained revenuefarming rights and judicial duties over the North-Eastern Frontier, as it was then known, through a 1765 diwani grant from the Great Mughal in Delhi, the EIC aspired first and foremost to revive the administration of revenue in the region, adding a monopoly in territory to their existing monopolies in the eastern trade. Given these primarily commercial interests, it should come as no surprise that the EIC's map-makers, their eyes fixed on the web of lucrative trade routes crisscrossing the region, homed in on the North-Eastern Frontier as the central point in "a synoptic vision that connected Bengal to China" (72. ...

    Outbreaks of eastern equine encephalitis observed from May 2008 to August 2009 in the Brazilian states of Pernambuco, Ceará, and Paraíba are reported. The disease occurred in 93 farms affecting 229 equids with a case fatality rate of 72.92%. Main clinical signs were circling, depression or hyperexcitability, ataxia, and progressive paralysis with a clinical manifestation period of 3-15 days. Main histologic lesions were a diffuse lymphocytic encephalomyelitis with neuronal death, satellitosis, neuronophagia, and hemorrhages being more severe in the cerebral gray matter of the telencephalon, diencephalon, and mesencephalon. Some animals also had areas of malacia in the telencephalon, thalamus, and basal nuclei. From 1 case, the virus was isolated by mice inoculation, and in other 13 cases was identified as Eastern equine encephalitis virus by semi-nested reverse transcription polymerase chain reaction. After DNA sequencing, all samples were identified as eastern equine encephalitis through the BLASTn analysis, but samples from the Ceará and Paraíba states corresponded to the same cluster, while the sample from the state of Pernambuco corresponded to a different cluster. © 2011 The Author(s)

    Surface rights issues regarding pipelines and flow lines in the province of British Columbia were discussed. The recent legislative developments in the province regarding the jurisdiction of the Mediation and Arbitration Board with respect to geophysical exploration, were reviewed. Applications to the Board are made when there is a refusal on the part of an owner to grant a surface lease satisfactory to the party seeking access to the land. The Board can then convene a mediation hearing to resolve the matter. Recent Mediation and Arbitration Board decisions were reviewed. Prior to 1995, the Board did not deal with cases relating to seismic operations. However, in 1995, the Board received an application from landowners requesting that a hearing be held to assess compensation for damages caused in the course of seismic operations conducted on the landowner's land. The Board decided that it had jurisdiction to hear the case and assess damages. At present, jurisdiction of the Board does not extend to pipelines., a shortcoming that should be remedied in order that the Board can appropriately deal with all intra-provincial pipeline surface right issues. Text of part 3 of the Petroleum and Natural Gas Act and Part 7 of the Railway Act, relevant to the subject under discussion, are appended

    Full Text Available Outbreaks of cutaneous leishmaniasis are relatively common among soldiers involved in nocturnal activities in tropical forests. We investigated the population dynamics of sand flies in a military training camp located in a remnant of Atlantic rainforest in northeastern Brazil, where outbreaks of cutaneous leishmaniasis have sporadically been described. From July 2012 to July 2014, light traps were monthly placed in 10 collection sites, being nine sites located near the forest edge and one near a sheep and goat stable. Light traps operated from 5:00 pm to 6:00 am, during four consecutive nights. Leishmania infection in sand flies was assessed using a fast real-time PCR assay. Cases of cutaneous leishmaniasis among soldiers were also investigated. In total, 24,606 sand flies belonging to 25 species were identified. Males (n = 12,683 predominated over females (n = 11,923. Sand flies were present during all months, being more numerous in March (n = 1,691 and April 2013 (n = 3,324. Lutzomyia choti (72.9% was the most abundant species, followed by Lutzomyia longispina (13.8%, Lutzomyia complexa (5.3%, representing together >90% of the sand flies collected. Forty cases of cutaneous leishmaniasis were recorded among soldiers from January 2012 to December 2014. Leishmania isolates were obtained from eight patients and were all characterized as Leishmania braziliensis. Soldiers and anyone overnighting in Atlantic rainforest remnants should adopt preventative measures such as the use of repellents on bare skin or clothes and insecticide-treated tents.

    Occult hepatitis B infection (OBI) is considered to be one of the major risks for patients suffering from end-stage renal disease (ESRD) on regular hemodialysis (HD) and patients with chronic hepatitis C virus (HCV) infection. This study compared the prevalence of OBI among these two high-risk groups in the Suez Canal region, Northeastern Egypt, to obtain a better national overview of the magnitude of OBI in this region. Serum samples were collected from 165 HD patients and 210 chronic HCV-infected patients. Anti-HCV antibody, hepatitis B surface antigen (HBsAg), total hepatitis B core (anti-HBc) antibody, and hepatitis B surface antibody (anti-HBs) were detected by enzyme-linked immunosorbent assay (ELISA). HCV RNA was detected using a quantitative real-time RT-PCR assay, and HBV was detected using a nested PCR. All patients were negative for HBsAg. A total of 49.1% and 25.2% of the patients in the HD and HCV groups, respectively, were anti-HBc-positive. In addition, more anti-HBs-positive patients were detected in the HD group compared to the HCV group (52.1% and 11.4%, respectively). Three cases were positive for HBV DNA in the HD group, while eighteen positive cases were detected in the HCV group. Both study groups showed significant differences in serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) level as well as anti-HBc, anti-HBs and HBV-DNA positivity. OBI was more prevalent among chronic HCV patients than HD patients in the Suez Canal region, Egypt, with rates of 8.5% and 1.8%, respectively. However, more precise assessment of this infection requires regular patient follow-up using HBV DNA detection methods.

    The primary objective of this study is to conduct a preliminary dynamic analysis of two realistic hybrid energy systems (HES) including a nuclear reactor as the main baseload heat generator (denoted as nuclear HES or nuclear hybrid energy systems [[NHES]) and to assess the local (e.g., HES owners) and system (e.g., the electric grid) benefits attainable by the application of NHES in scenarios with multiple commodity production and high penetration of renewable energy. It is performed for regional cases not generic examples based on available resources, existing infrastructure, and markets within the selected regions. This study also briefly addresses the computational capabilities developed to conduct such analyses, reviews technical gaps, and suggests some research paths forward.

  1. The Rock Engineering System (RES) applied to landslide susceptibility zonation of the northeastern flank of Etna: methodological approach and results

    2015-04-01

    Ground deformations in the northeastern flank of Etna are well known. Despite only a few landslide events have been documented, these have significantly involved and damaged lifelines and buildings. These events are mainly related to the activity of the volcano-tectonic structures and associated seismicity, as in the case of the 2002 reactivation of the Presa landslide during an increased activity of the Pernicana fault system. In order to highlight the areal distribution of potentially unstable slopes based on a detailed, site-specific study of the factors responsible for landslide, and to ultimately contribute to risk management, a landslide susceptibility analysis of the northeastern flank of Etna in the Pernicana area was carried out, and a susceptibility map at 1:10.000 scale was produced, extending over an area of 168 km2. Different methods are proposed in the literature to obtain the regional distribution of potentially unstable slopes, depending on the problem scale, the slope dynamic evolution in the geological context, and the availability of data. Among semi-quantitative approaches, the present research combines the Rock Engineering System (RES) methodology with parameter zonation mapping in a GIS environment. The RES method represents a structured approach to manage a high number of interacting factors involved in the instability problem. A numerically coded, site-specific interaction matrix (IM) analyzes the cause-effect relationship in these factors, and calculates the degree of interactivity of each parameter, normalized by the overall interactivity of the system (weight factor). In the specific Etna case, the considered parameters are: slope attitude, lithotechnical properties (lithology, structural complexity, soil and rock mass quality), land use, tectonic structures, seismic activity (horizontal acceleration) and hydrogeological conditions (groundwater and drainage). Thematic maps are prepared at 1:10.000 scale for each of these parameters, and

To describe clinical and pathologic characteristics of patients with coccidioidomycosis (CM) who died from 1983-2000 at a hospital in northeastern Mexico, and 2, to know distribution of number of deaths due to CM per year and month. From 4598 autopsies, 31 cases of CM were selected. Clinical chart and autopsy protocols were examined. Distribution of cases was analyzed by contingence table and Kolmogorov-Smirnov tests. There were 10 women and 21 men (aged 4 months to 60 years). In women, pregnancy was present in 40% of cases. In men, chronic renal failure (CRF) (38%) and AIDS (19%) were the pathologic conditions most frequently observed. Variation in distribution of cases throughout 18 years was not observed (p > 0.05). Mortality due to CM was 0.67% and variation in number of deaths was not found. In this endemic area, CM must be included in differential diagnosis of patients with risk factors such as pregnancy, CRF, and AIDS, especially if associated with pneumonia with miliary pattern or septicemia with splenomegaly.

    One of the essential steps in targeting tuberculosis (TB) intervention is early diagnosis and treatment of patients by reducing the reservoir of infection in the community. In the North-Eastern (NE) region of India pulmonary TB and paragonimiasis are overlapping public health issues. We performed a cross-sectional study in 63 remote villages from the two states Arunachal Pradesh (AP) and Assam to determine the prevalence of undiagnosed TB and paragonimiasis cases using cough as a simple indicator. In AP, 2961 individuals aged five years and above were examined and 1108 (37·4%) were found to have cough for one week or more. Of the 417 individuals who provided sputum, 11 (2·64%) were smear positive for acid-fast bacilli (AFB). All these cases were yet undiagnosed, thus the prevalence of new smear positive TB in AP was 0·37%. In Assam on the other hand 331 (23·5%) subjects out of 1410 individuals who were examined had a cough for one week or more and of the 112 individuals who provided sputum, 13 (11·6%) were smear positive for AFB. The prevalence of new smear positive TB cases was 0·78% in Assam. Sero-positivity of paragonimiasis in coughers of AP was 7·6% (n = 1091), which was significantly higher (p NE region of India especially in the remote places and there is need to strengthen early case detection of TB.

    Strontium isotopic ratios of sixty-seven Tertiary volcanic rocks from the northeastern Honshu, Japan, were determined for the purpose of examining the genesis among the volcanic rocks. Two distince suites of volcanic rocks occur in the northeastern Honshu; the rocks older than 16 Ma (Monzen-Daijima Stege) of predominantly intermediate composition and the rocks younger than 16 Ma (Nishikurosawa-Funakawa Stege) with bimodal suite of mafic and felsic composition. Initial values of 87 Sr/ 86 Sr in the Teriary volcanic rocks from the northeastern Honshu, lie in the range from 0.7033 to 0.7068. High ( 87 Sr/ 86 Sr) I ratios are observed for the rocks older than 16 Ma from the Japan Sea side (H zone). It is noteworthy that the rocks younger than 16 Ma show significantly lower ( 87 Sr/ 86 Sr) I ratios in the Dewa Hill, Japan Sea coast and North Akita areas in the northeastern Honshu (L zone). The rocks younger than 16 Ma from the L zone can also be interpreted as having been originated as a mantle-diapir associated with the spreading of the Japan Sea basin. If the basaltic magma was formed from the diapir, the 87 Sr/ 86 Sr ratio would be close to the range from 0.7033 to 0.7037 as the low-Sr isotopic ratio zone (L zone) in the northeastern Honshu, Japan.

    Full Text Available In the treatment of mental disorders, nonadherence to medication, the main cause of psychiatric morbidity, is observed in about 50% of the cases and is responsible for numerous losses. This study evaluated adherence to drug treatment by patients seen in a Psychosocial Care Center (CAPS in northeastern Brazil. Adherence to treatment was evaluated using the Haynes-Sackett and Morisky-Green-Levine tests. All patients registered in the CAPS were included in the study (n= 101. Only 11.88% of the patients adhered to drug treatment. The main reasons not to use medication were: oblivion (68.83%, feeling unwell after taking the medication (54.22%, not having money to buy the medication (43.83%, not finding the medication in the public health service (39.94% and fear of harm that might be caused by the drug (28.90%. Furthermore, 85.1% of the patients did not know their diseases, 88.1% did not know their treatment, 86.4% did not feel good when they took their medication, and 88.1% took their medication incorrectly. The results revealed that the lack of information about diseases and drugs used, the nuisance posed by drug therapy and the low access to medications reduce adherence to treatment and, consequently, treatment effectiveness.No tratamento de desordens mentais, a não-adesão ao tratamento ocorre em cerca de 50% dos casos e é responsável por inúmeros prejuízos, além de ser a principal causa de morbidade psiquiátrica.

    India is like a microcosm of the world in terms of its diversity; religion, climate and ethnicity which leads to genetic variations in the populations. As a highly polymorphic marker, the human leukocyte antigen (HLA) system plays an important role in the genetic differentiation studies. To assess the genetic diversity of HLA class II loci, we studied a total of 1336 individuals from north India using DNA-based techniques. The study included four endogamous castes (Kayastha, Mathurs, Rastogies and Vaishyas), two inbreeding Muslim populations (Shias and Sunnis) from north India and three northeast Indian populations (Lachung, Mech and Rajbanshi). A total of 36 alleles were observed at DRB1 locus in both Hindu castes and Muslims from north, while 21 alleles were seen in northeast Indians. At the DQA1 locus, the number of alleles ranged from 11 to 17 in the studied populations. The total number of alleles at DQB1 was 19, 12 and 20 in the studied castes, Muslims and northeastern populations, respectively. The most frequent haplotypes observed in all the studied populations were DRB1*0701-DQA1*0201-DQB1*0201 and DRB1*1501-DQA1*0103-DQB1*0601. Upon comparing our results with other world populations, we observed the presence of Caucasoid element in north Indian population. However, differential admixturing among Sunnis and Shias with the other north Indians was evident. Northeastern populations showed genetic affinity with Mongoloids from southeast Asia. When genetic distances were calculated, we found the north Indians and northeastern populations to be markedly unrelated.

    Full Text Available Farming is the main occupation of the rural people in Northeastern region of Nigeria. It constitutes 60-75% of the population of the area and involves both male and female alike. However, a postharvest aspect of production is mostly handled by women. Thus the female farmers are more exposed to farming occupational hazards than their male counterparts. The aim of the study was to identify the occupational hazard problems encountered by female farmers in Northeastern region of Nigeria. Specifically, to (i determine the prevalence of injuries and diseases of women farmers; (ii assess types of treatments available to women farmers; and (iii assess the protective measures employed in preventing injuries and diseases. A cross-sectional descriptive study was conducted using a pre-tested questionnaire to collect data. Eight hundred questionnaires were administered. Multistage sample method was used to select the respondents. The results showed that 662 (82.8% of the female farmers interviewed complained of back pains. Six hundred and twenty-four or (78.0% of the respondents suffered lacerations from the usage of farm implements such as hoes, axes, sickles, cutlass, and also from grasses and thorns. Insect stings were the third most prevalent diseases and constitute 59.5% of the respondents. Other diseases prevalence were: sunburns, snake bites, fractures, and injuries from falling trees and branches, which constitute 20.6% of the farmers. The respondents got treatments at homes, traditional healers, and hospitals. The use of chemicals was not popular among the respondents, herbicides, (9.8%, pesticides, (13.1% and insecticides (21.4%. Accordingly, the awareness of the harmful effects of these chemicals was low. Farming activities of the women farmers in northeastern, Nigeria was found to be their means of livelihoods. There is a need to increase agricultural mechanization in order to reduce injuries and pains associated with crude farm tools. Female

    In northeastern Brazil, large swaths of once-productive soils have been severely degraded by soil salinization, but the true extent of the damage has not been assessed. Emerging remote sensing technology based on hyperspectral analysis offers one possibility for large-scale assessment, but it has been unclear to what extent the spectral properties of soils are related to salinity characteristics. The purpose of this study was to characterize the spectral properties of degraded (saline) and non-degraded agricultural soils in northeastern Brazil and determine the extent to which these properties correspond to soil salinity. We took soil samples from 78 locations within a 45,000-km 2 site in Pernambuco State. We used cluster analysis to group the soil samples on the basis of similarities in salinity and sodicity levels, and then obtained spectral data for each group. The physical properties analysis indicated a predominance of the coarse sand fraction in almost all the soil groups, and total porosity was similar for all the groups. The chemical analysis revealed different levels of degradation among the groups, ranging from non-degraded to strongly degraded conditions, as defined by the degree of salinity and sodicity. The soil properties showing the highest correlation with spectral reflectance were the exchangeable sodium percentage followed by fine sand. Differences in the reflectance curves for the various soil groups were relatively small and were not significant. These results suggest that, where soil crusts are not present, significant challenges remain for using hyperspectral remote sensing to assess soil salinity in northeastern Brazil.

    A cross-site analysis was conducted on seven diverse, forested watersheds in the northeastern United States to evaluate hydrological responses (evapotranspiration, soil moisture, seasonal and annual streamflow, and water stress) to projections of future climate. We used output from four atmosphere–ocean general circulation models (AOGCMs; CCSM4, HadGEM2-CC, MIROC5, and MRI-CGCM3) included in Phase 5 of the Coupled Model Intercomparison Project, coupled with two Representative Concentration Pathways (RCP 8.5 and 4.5). The coarse resolution AOGCMs outputs were statistically downscaled using an asynchronous regional regression model to provide finer resolution future climate projections as inputs to the deterministic dynamic ecosystem model PnET-BGC. Simulation results indicated that projected warmer temperatures and longer growing seasons in the northeastern United States are anticipated to increase evapotranspiration across all sites, although invoking CO2 effects on vegetation (growth enhancement and increases in water use efficiency (WUE)) diminish this response. The model showed enhanced evapotranspiration resulted in drier growing season conditions across all sites and all scenarios in the future. Spruce-fir conifer forests have a lower optimum temperature for photosynthesis, making them more susceptible to temperature stress than more tolerant hardwood species, potentially giving hardwoods a competitive advantage in the future. However, some hardwood forests are projected to experience seasonal water stress, despite anticipated increases in precipitation, due to the higher temperatures, earlier loss of snow packs, longer growing seasons, and associated water deficits. Considering future CO2effects on WUE in the model alleviated water stress across all sites. Modeled streamflow responses were highly variable, with some sites showing significant increases in annual water yield, while others showed decreases. This variability in streamflow responses poses a

    Full Text Available BACKGROUND: There is an urgent need for an improved understanding of the sources, distributions and properties of atmospheric aerosol in order to control the atmospheric pollution over northeastern Himalayas where rising anthropogenic interferences from rapid urbanization and development is becoming an increasing concern. METHODOLOGY/PRINCIPAL FINDINGS: An extensive aerosol sampling program was conducted in Darjeeling (altitude approximately 2200 meter above sea level (masl, latitude 27 degrees 01'N and longitude 88 degrees 15'E, a high altitude station in northeastern Himalayas, during January-December 2005. Samples were collected using a respirable dust sampler and a fine dust sampler simultaneously. Ion chromatograph was used to analyze the water soluble ionic species of aerosol. The average concentrations of fine and coarse mode aerosol were found to be 29.5+/-20.8 microg m(-3 and 19.6+/-11.1 microg m(-3 respectively. Fine mode aerosol dominated during dry seasons and coarse mode aerosol dominated during monsoon. Nitrate existed as NH(4NO(3 in fine mode aerosol during winter and as NaNO(3 in coarse mode aerosol during monsoon. Gas phase photochemical oxidation of SO(2 during premonsoon and aqueous phase oxidation during winter and postmonsoon were the major pathways for the formation of SO(4(2- in the atmosphere. Long range transport of dust aerosol from arid regions of western India was observed during premonsoon. The acidity of fine mode aerosol was higher in dry seasons compared to monsoon whereas the coarse mode acidity was higher in monsoon compared to dry seasons. Biomass burning, vehicular emissions and dust particles were the major types of aerosol from local and continental regions whereas sea salt particles were the major types of aerosol from marine source regions. CONCLUSIONS/SIGNIFICANCE: The year-long data presented in this paper provide substantial improvements to the heretofore poor knowledge regarding aerosol chemistry over

    There is an urgent need for an improved understanding of the sources, distributions and properties of atmospheric aerosol in order to control the atmospheric pollution over northeastern Himalayas where rising anthropogenic interferences from rapid urbanization and development is becoming an increasing concern. An extensive aerosol sampling program was conducted in Darjeeling (altitude approximately 2200 meter above sea level (masl), latitude 27 degrees 01'N and longitude 88 degrees 15'E), a high altitude station in northeastern Himalayas, during January-December 2005. Samples were collected using a respirable dust sampler and a fine dust sampler simultaneously. Ion chromatograph was used to analyze the water soluble ionic species of aerosol. The average concentrations of fine and coarse mode aerosol were found to be 29.5+/-20.8 microg m(-3) and 19.6+/-11.1 microg m(-3) respectively. Fine mode aerosol dominated during dry seasons and coarse mode aerosol dominated during monsoon. Nitrate existed as NH(4)NO(3) in fine mode aerosol during winter and as NaNO(3) in coarse mode aerosol during monsoon. Gas phase photochemical oxidation of SO(2) during premonsoon and aqueous phase oxidation during winter and postmonsoon were the major pathways for the formation of SO(4)(2-) in the atmosphere.

    Toxolasma gondii is one of the most important obligate intracellular protozoan parasites. Recently, toxoplasmosis is of increasing concerns because T. gondii not only has a worldwide distribution but also can infect virtually all warm-blooded hosts including donkeys. However, limited information is available concerning the genetic characterization of T. gondii in donkeys in northeastern China. In this study, a total of 302 brain tissue samples collected from donkeys from Jilin (n=108) and Liaoning (n=194) provinces, northeastern China, were examined for T. gondii infection by semi-nested PCR of B1 gene. The positive samples were genotyped at 11 loci (i.e., SAG1, alternative SAG2, 5'-and 3'-SAG2, SAG3, L358, BTUB, c22-8, GRA6, c29-2, PK1 and Apico) using polymerase chain reaction-restriction fragment length polymorphism technology. Of 302 brain tissue samples, 19 (6.29%) were PCR-positive for T. gondii. The prevalence rates of T. gondii were 6.48% (7/108) and 6.19% (12/194) in Jilin Province and Liaoning Province, respectively. The prevalence of T. gondii in different season groups varied from 5.56% to 7.41%. The prevalence of T. gondii in "Cage-free" donkeys was higher than that in "Captive" donkeys. Of the 19 positive samples, only two isolates were successfully genotyped at all loci, three were genotyped at 9 loci. In total, four samples belong to ToxoDB genotype #9, one belong to ToxoDB genotype #10. This is firstly characterized the T. gondii isolates from donkeys in northeastern China. The results of the present study will improve the information of the distribution of T. gondii genotypes in China. Copyright © 2017. Published by Elsevier B.V.

    Stable isotope and radiocarbon data of groundwater stored in Quaternary aquifers in North-Eastern Hungary can not be explained by climatic changes alone. More than two hundred δD, δ 18 O and radiocarbon ages of waters from 79 wells show that the recharge are changed during the time of upper pleniglacial and late glacial. Groundwaters of the studied are can be divided into three categories, which can explain their origin. The data are consistent with geomorphological results giving isotope evidence of hydrology for a geodynamical event during the mentioned periods. (R.P.) 3 refs.; 2 figs

    A study of bottom sediments conducted on the 100th cruise of R/V Professor Shtokman in the northeastern part of the Black Sea along the section from the Kerch Strait to the deep-sea depression allowed estimation of Holocene sulfide sedimentation and consideration of the accompanying diagenetic processes, which involve reactions with C, N, and P. The behavior of dissolved forms of Mn and Fe is considered from the viewpoint of their different solubility and formation of sulfides. The redox system of the Black Sea sediments can significantly be expanded at the expense of the migration methane and hydrogen, which accompanies its anaerobic oxidation.

    This study links models of global climate circulation, ecology, and economic valuation (hedonic travel cost and random utility models) to value the impact of global warming on freshwater sportfishing in the Northeast. An origin-specific linear random utility model (RUM) is introduced. The results of the RUM are shown to be comparable to those of a hedonic travel cost model. A doubling of atmospheric carbon dioxide is predicted to generate between a $4.6 million loss and a $20.5 million net benefit for the Northeastern United States, depending on the climate scenario.

    The Amur Tiger (Panthera tigris altaica) is one of the world's most endangered species. Recently, habitat fragmentation, food scarcity and human hunting have drastically reduced the population size and distribution areas of Amur tigers in the wild, leaving them on the verge of extinction. Presently, they are only found in the north-eastern part of China. In this study, we developed a reference framework using methods and technologies of analytic hierarchy process (AHP), remote sensing (RS), geographic information system (GIS), GAP analysis and Natural Break (Jenks) classification to evaluate the habitat and to set the conservation priorities for Amur tigers in eastern areas of Heilongjiang and Jilin Provinces of northeast China. We proposed a Habitat Suitability Index (HSI) incorporating 7 factors covering natural conditions and human disturbance. Based on the HSI values, the suitability was classified into five levels from the most to not suitable. Finally, according to results of GAP analysis, we identified six conservation priorities and designed a conservation landscape incorporating four new nature reserves, enlarging two existing ones, and creating four linkages for Amur tigers in northeast China. The case study showed that the core habitats (the most suitable and highly suitable habitats) identified for Amur tigers covered 35,547 km(2), accounting for approximately 26.71% of the total study area (1,33,093 km(2)). However, existing nature reserves protected only (7124 km(2) or) 20.04% of the identified core habitats. Thus, enlargement of current reserves is necessary and urgent for the tiger's conservation and restoration. Moreover, the establishment of wildlife corridors linking core habitats will provide an efficient reserve network for tiger conservation to maintain the evolutionary potential of Amur tigers facing environmental changes.

From Moessbauer results, the sample compositions differ from one area to the other. Spectra from both soil samples are dominated by the Fe{sup 3+ } paramagnetic signal. For soil samples from the coastal area, the {alpha}-Fe{sub 2}O{sub 3} contribution is lower, Fe{sub 3}O{sub 4} was not detected, and the relative areas of each spectral contribution are nearly constant with depth. For samples from the inland area, the Fe{sup 3+ } paramagnetic fraction increases up to 82%, mainly at the expense of the magnetically ordered phase. The main observed activity originates from the decay of {sup 40}K (540-750 Bq/kg), followed by {sup 238}U (60-92 Bq/kg) and {sup 232}Th (37-46 Bq/kg) chains. The activity of {sup 235}U was in all the cases lower than the detection limit (L{sub D} = 0.02 Bq/kg). The only determined anthropogenic nuclide was {sup 137}Cs, arising from the fallout of the Southern Hemisphere nuclear weapon tests. Three of the observed differences in the depth distributions can be described by the dispersion-convection model. A correlation between the natural nuclide activities and the Moessbauer relative fractions was found, whereas no correlation was found between the {sup 137}Cs profile and the relative fraction of Fe{sub 3}O{sub 4} or with other iron species.

    The activity concentrations of both natural (238U and 232Th chains and 40K) and anthropogenic (137Cs) radionuclides down along the soil profile have been determined in soil samples collected from inland and coastal areas of the La Plata River, located in the Northeastern region of the Province of Buenos Aires, Argentina. These studies were complemented with 57Fe Mössbauer spectroscopy characterization, pH, texture and organic carbon content measurements. From Mössbauer results, the sample compositions differ from one area to the other. Spectra from both soil samples are dominated by the Fe3+ paramagnetic signal. For soil samples from the coastal area, the α-Fe2O3 contribution is lower, Fe3O4 was not detected, and the relative areas of each spectral contribution are nearly constant with depth. For samples from the inland area, the Fe3+ paramagnetic fraction increases up to 82%, mainly at the expense of the magnetically ordered phase. The main observed activity originates from the decay of 40K (540-750 Bq/kg), followed by 238U (60-92 Bq/kg) and 232Th (37-46 Bq/kg) chains. The activity of 235U was in all the cases lower than the detection limit (LD = 0.02 Bq/kg). The only determined anthropogenic nuclide was 137Cs, arising from the fallout of the Southern Hemisphere nuclear weapon tests. Three of the observed differences in the depth distributions can be described by the dispersion-convection model. A correlation between the natural nuclide activities and the Mössbauer relative fractions was found, whereas no correlation was found between the 137Cs profile and the relative fraction of Fe3O4 or with other iron species.

    :  Streptococcus phocae is a pathogen of marine mammals, although its pathogenicity remains poorly understood. Recovery of this bacterium from asymptomatic carriers suggests that it is an opportunistic pathogen. We investigated the role of S. phocae in naturally occurring disease and its significance as a pathogen based on postmortem investigations. Between 2007 and 2012, 1,696 whole carcasses, tissue samples, or both were submitted from the northeastern Pacific and Arctic Canada for diagnostic testing. Streptococcus phocae was cultured from phocids ( n=66), otariids ( n=12), harbor porpoises ( Phocoena phocoena; n=5), and sea otters ( Enhydra lutris; n=2). Pathologic manifestations of S. phocae-associated disease included localized, as well as systemic, inflammatory lesions with common findings of suppurative bronchopneumonia ( n=17) and bacteremia ( n=27). Lung lesions were frequently culture-positive for S. phocae, suggesting commensal colonization of the oropharynx with subsequent opportunistic infection of the respiratory tract during tissue injury, coinfection, immunosuppression, or other debilitating conditions. The presence of a positive spleen culture, and interpretations at necropsy and histopathology, were used to determine the presence of S. phocae bacteremia. Less frequent lesions that were culture positive for S. phocae included abscesses ( n=9), meningitis ( n=7), and cellulitis ( n=1). The majority of cases with S. phocae lesions featured pre-existing conditions that presumably contributed to some degree of debilitation or immunosuppression, including emaciation ( n=29), liver mercury accumulation ( n=29), trauma ( n=22), severe pulmonary or cardiovascular nematodiasis ( n=9), concurrent bacterial or viral infections ( n=8), or sarcocystosis ( n=6). These findings suggest that S. phocae could be characterized as an opportunistic pathogen, associated with debilitating conditions in stranded and rehabilitating marine mammals.

    Some areas of the Tuzla region (B and H) suffer heavily from the shortage of quality drinking water. The only real long-term water resource in this region is the Lake Modrac, the largest accumulation lake in Bosnia and Herzegovina. Due to the fact that radon is soluble in water it can be transported by water to long distances. In cases of intake of waters rich in radon the most affected are sensitive cells within the abdomen and other internal organs. In order to satisfy the needs for drinking water, people are forced to excavate and drill wells. In the area of Tuzla region and the entire B and H excavated wells are very frequent, and so are drilled wells lately, due to more developed and cheaper technology for soil drilling. Such activities in this area, and the whole of B and H, are carried out in an unorderly manner and without previously completed chemical and radiological analyses of soil and water samples. The University of Tuzla formed the Laboratory for detection of radon in all environments, and the survey displayed in this paper have been the first investigation of that kind in B and H. Here we presented the results of radon survey of drinking waters from excavated and drilled wells in the area of Tuzla region (North-Eastern region of B and H). The measurements were conducted over the period of one year (2006), so as to make possible monitoring of variations of radon concentrations in dependence of meteorological changes. These investigation works showed that radon concentration at most locations was significantly higher in drilled wells than in excavated wells. Mean values of radon concentration in the tested water samples ranged within the interval of 101-4200 Bq/m 3 . Radon activity concentration was measured with the Alpha GAURD radon system (Genitron instruments-Frankfurt). (author)

    The highlands of northeastern Honduras remain under-characterized in terms of biological diversity, as exemplified by the regularity of new amphibian and reptile taxa discoveries. Following the recent description of a new species of Nototriton from the Sierra de Agalta in northeastern Honduras, we report the discovery of a second new species of Nototriton from the nearby Parque Nacional Montaña de Botaderos. This new taxon, Nototriton mime sp. nov., is distinguished from other Nototriton by its distinctive pale brown dorsal coloration in adult males, relatively large nares, a relatively broad head, mitochondrial sequence divergence, and phylogenetic relationships, and is geographically isolated from other populations of Nototriton.

    Full Text Available The settlement of the territory of north-eastern Serbia by the representatives of the Coţofeni culture began during the second half of the IV millennium, probably under the pressure of invading tribes from Euroasian steppe. This territory extended over Transylvania, Banat, Oltenia and Muntenia (Map 2. On the territory of Serbia they settled from the Djrerdap gorge up to the Mlava river to the west, and through Kučajske mountains, Bor, Zaječar and further to the south, up to Niš. Aspecific symbiosis occurred on the territory of Serbia between the Coţofeni and the Kostolac cultures. According to the results of the latest project of re-identification, the number of Coţofeni-Kostolac sites and settlements increased to 76. After all the sites were re-identified and georeferenced, with consideration of the surrounding landscape, hydrography, geomorphology of the terrain and the character of the ceramic production finds, we believe that there is a need for re-analyzing specific aspects of the cultural and geographic development not only of settlements, but of the entire Coţofeni-Kostolac cultural phenomenon. In this paper we considered three archaeological sites in the Nišava valley, given that re-identification work over the past several years yielded new information (Bubanj-Staro Selo, Velika Humska čuka and Donja Vrežina. The topography of Coţofeni-Kostolac settlements on the territory of north-eastern Serbia, the Serbian part of the Danube valley and its hinterland, is characterized by diversity of position (location above sea level and landscape placement, types of houses and economic survival. In the 70’s of the last century sites were identified that are located in very inaccessible terrain, which in particular cases has an slope incline of 45°, where the number of such settlements in the meantime increased to nine.

    A study, using satellite telemetry, was conducted to determine the precise migration patterns and wintering locations of Common Loons (Gavia immer) breeding in the northeastern United States. Transmitters were implanted in 17 loons (16 adults and one juvenile) that were captured on breeding lakes in New York, New Hampshire, and Maine during the summers of 2003, 2004, and 2005. Transmitters from ten of the birds provided adequate location data to document movement to wintering areas. Most adult loons appeared to travel non-stop from breeding lakes, or neighboring lakes (within 15 km), to the Atlantic coast. Adult loons marked in New Hampshire and Maine wintered 152 to 239 km from breeding lakes, along the Maine coast. Adult loons marked in the Adirondack Park of New York wintered along the coasts of Massachusetts (414 km from breeding lake), Rhode Island (362 km), and southern New Jersey (527 km). Most of the loons remained relatively stationary throughout the winter, but the size of individual wintering areas of adult loons ranged from 43 to 1,159 km 2, based on a 95% fixed kernel utilization distribution probability. A juvenile bird from New York made a number of stops at lakes and reservoirs en route to Long Island Sound (325 km from breeding lake). Maximum functional life of transmitters was about 12 months, providing an opportunity to document spring migration movements as well. This work provides essential information for development and implementation of regional Common Loon conservation strategies in the Northeastern U.S.

    Full Text Available The reproductive biology of round sardinella, Sardinella aurita Valenciennes, 1847, was studied for the first time in the north-eastern Mediterranean Sea. Round sardinella has gained much attention lately because of its biomass increase, which might be the result of climatic changes occurring across the Mediterranean Sea. Monthly samples were collected on board commercial purse-seiners for two complete year cycles (September 2000 to August 2002. Round sardinella is a gonochoristic fish. The overall female to male ratio was not statistically different (P=0.34 from unity, although it varied monthly and with the length of the fish. The seasonal changes in the gonadosomatic index and the macroscopic characteristics of gonads showed that round sardinella in the northern Aegean spawns between May and July. Male round sardinella reach first sexual maturity at a smaller total length than females (155.0 and 168.3 mm respectively. Mean absolute fecundity (FA increased exponentially with body length (FA=0.0949xL4.22 and weight (FA=511.19xW1.02, with an average of ~21,000 oocytes produced per spawning female. Relative fecundity (FR ranged between 242 and 681 oocytes/g of body weight (average: 445 oocytes/g. The frequency distribution of oocytes showed that round sardinella produces a single batch of oocytes. In general, the reproductive characteristics of round sardinella in the north-eastern Mediterranean Sea differed when compared to stocks from other areas of its distribution.

    In northeastern China,large area of vegetable land has been simultaneously polluted by cadmium (Cd) and lead (Pb).Joint effects of Cd and Pb on Chinese cabbage (Brassica pekinensis L.) were investigated using the seed germination and sand culture method.Four Chinese cabbage cultivars including Kangbingjinchun (KB),Dongyangchunxia (DY),Qinglvwang (QL) and Qiangshi (QS) from Shenyang in northeastern China were adopted in this study.The results showed that there were positive linear relationships between the inhibitory rate of biomass,root and shoot elongation and the concentrations of Cd and Pb.In particular,root elongation was more sensitive to joint stress of Cd and Pb.The activity of superoxide dismutase (SOD) and the content of malondialdehyde (MDA),soluble protein (SP) and proline (PRO) changed significantly with increasing exposure concentration of Cd and Pb.The decrement in the activity of antioxidative enzymes,the content of SP and accumulation of MDA were relatively low in KB and QS.PRO played an important role in resisting Cd and Pb stress.

    Full Text Available We report here the occurrence of seasonal changes in the pigmentation of colonies of Siderastrea spp. during bleaching events on coastal reefs in northeastern Brazil. Bleached affected almost 50% of coral colonies analyzed in Cabo Branco reefs (Paraiba state in the summer of 2005. The same phenomenon was detected along various coastal reefs in northeastern Brazil during the summer of 2007 and 2008. These events were seasonal, and began with the emergence of pale colonies that became pale-pink and then purple during the rainy months. The patterns and intensity of colonies pigmentation changes varied with the studied sites. The decrease in zooxanthellae density and chlorophyll-a content was quantified in the colonies with their pigmentation pattern altered (bleaching. Microbiological analyses revealed higher densities of bacteria in pink colonies (bleached as compared to brown colonies (normal. Environmental disturbances may lead to the pigmentation changes in Siderastrea spp., but the immediate causes of this phenomenon are not clear and require further investigations.

    Altered atmospheric circulation, reductions in Arctic sea ice, ocean warming, and changes in evaporation and transpiration are driving changes in the global hydrologic cycle. Precipitation isotopic (δ18O and δ2H) measurements can help provide a mechanistic understanding of hydrologic change at global and regional scales. To study the changing water cycle in the northeastern US, we examined the longest (1968-2010) record of precipitation isotope values, collected at the Hubbard Brook Experimental Forest in New Hampshire, US (43o56‧N, 71o45‧W). We found a significant reduction in δ18O and δ2H values over the 43-year record, coupled with a significant increase in d-excess values. This gradual reduction in δ18O and δ2H values unexpectedly occurred during a period of regional warming. We provide evidence that these changes are governed by the interactions among the Atlantic Multidecadal Oscillation, loss of Arctic sea ice, the fluctuating jet stream, and regular incursions of polar air into the northeastern US.

    Extreme hydrologic events pose a present and future threat to cities and infrastructure in the densely populated coastal corridor of the northeastern United States (NE). An understanding of the potential range and return interval of storms, floods, and droughts is important for improving coastal management and hazard planning, as well as the detection and attribution of trends in regional climate phenomena. Here, we examine a suite of evidence for Common Era paleohydroclimate extreme events in the NE. Our study analyzes a network of hydroclimate sensitive trees, subfossil 'drowned' forests and co-located sediment records, using both classical and isotope dendrochronology, radiocarbon analyses, and sediment stratigraphy. Atlantic White cedar (AWC) forests grow along the NE coast and are exposed to severe coastal weather, as they are typically most successful in near-shore, glacially formed depressions. Many coastal AWC sites are ombrotrophic and contain a precipitation or drought signal in their ring widths. Sub-fossil AWC forests are found where near-shore swamps were drowned and exposed to the ocean. Additionally, the rings of coastal AWC may contain the geochemical signature of landfalling tropical cyclones, which bring with them a large influx of precipitation with distinct oxygen isotopes, which can be used to identify these large storms. Dendrochronology, radiocarbon dating, and analysis of sediment cores are used here to identify and date the occurrence of large overwash events along the coastline of the northeastern United States associated with extreme storms.

    Full Text Available The Khok Kruat Formation is the upper part of the Khorat Group, which consists of upper Lower Cretaceous non-marine sedimentary rocks in northeastern Thailand. Many dinosaur footprints have been known from the upper Lower Cretaceous (Aptian–Albian Khok Kruat Formation at the Huai Dam Chum (Tha Uthen site, northeastern Thailand. Approximately 600 tracks occur in thin mudstone layer of the northern part of the outcrop at the Huai Dam Chum track site. Two types of footprints, small-sized theropod and crocodylomorph are imprinted with mud cracks and ripple marks on the thin mud layer. Most of footprints are referred to cf. Asianopodus, and are imprinted by small-sized theropoda, probably ornithomimosauria. Theropod tracks are mainly separated into two groups, Group A and Group B. From ichnological viewpoints, the small-sized theropod track assemblage indicates the herd behaviour and its idiosyncratic group composition. In particular, the histogram of size-frequency measurements of Group A shows the anomalous bimodal distribution. We consider that there are two hypotheses; the first one is due to the male-female difference, and the second is a result of the different growing stage.

    The genus Curcuma is a very important economic plant. Members of this genus were used as food, medicine and ornament plants. The objectives of this study were to examine the geographic distributions and ecological conditions in the natural habitats of Curcuma in Northeastern Thailand. Species diversity was examined using the line transect method. Ecological conditions of the species were examined using a sampling plot of 20 x 20 m. A total of five species were found including Curcuma angustifolia Roxb., C. alismatifolia Gagnep., C. gracillima Gagnep., C. parviflora Wall. and C. rhabdota. These species were in an altitudinal range between 290 m and 831 m above sea level. Four species (C. angustifolia, C. alismatifolia, C. gracillima and C. rhabdota) were distributed in open gaps in dry dipterocarp forest. One species, C. parviflora was found in the contact zone between dry dipterocarp and bamboo (Gigantochloa sp.) forest. C. rhabdota was found only in a habitat with high humidity and shading along the Thailand-Lao PDR border. Significant ecological conditions of the natural habitats of these Curcuma species were identified. Altitude is the most important factor when determining the geographic distributions of these Curcuma species in Northeastern Thailand.

    Wolf (Canis lupus) and moose (Alces americanus) populations in northeastern Minnesota, USA, have fluctuated for decades and, based on helicopter counts, moose numbers declined to a new low from 2006 to about 2012. Other steep declines were found in 1991 and 1998 during periods when moose counts were done with ®xed-wing aircraft; these declines also appeared to be real. Winter wolf numbers, monitored in part of the moose range, had been increasing since about 2002 to the highest population in decades in 2009. However, from 2009 to 2016, wolves decreased precipitously, and the moose-population decline leveled off from 2012 to 2017. Calf:population ratios from 1985 to 1997 and from 2005 to 2016 were inversely related to wolf numbers in the wolf-study area the previous winter both as wolves increased and decreased in abundance. Similarly, log annual growth rates of moose numbers were negatively correlated with counts of wolves in the prior year. Other factors such as nutrition and parasites, and possibly climate change, likely have been involved in the recent moose decline. However, wolves, as in other areas, appear to have contributed to the decline in the northeastern Minnesota moose population at least in part through predation on calves, supporting earlier reports.

    Mercury emissions to the atmosphere from coal-fired power plants and other sources such as waste incineration can be deposited to landscapes in precipitation and in dry fallout. Some mercury reaches watersheds and streams, where it can accumulate in sediments and biota. Human exposure to mercury occurs primarily through fish consumption, and currently mercury fish eating advisories are in place for many of the streams and lakes in the state. Here, we explored mercury in air, soils, water, and biota. To quantify atmospheric mercury deposition, we measured both wet and dry mercury deposition at over 10 locations in Pennsylvania, from which we present variation in mercury deposition and initial assessments of factors affecting the patterns. Further, we simulated mercury deposition at unmonitored locations in Pennsylvania and the northeastern United States over space and time with a high-resolution modeling technique that reflects storm tracks and air flow patterns. To consider mercury accumulation in watersheds, we collected data on soil mercury concentrations in a set of soil samples, and collected baseline data on mercury in streams draining 35 forested watersheds across Pennsylvania, spanning gradients of atmospheric deposition, climate and geology. Mercury concentrations were measured in stream water under base-flow conditions, in streambed sediments, aquatic mosses, and in fish tissues from brook trout. Results indicate that wet and dry atmospheric deposition is a primary source of mercury that is accumulating in watersheds of Pennsylvania and the northeastern United States.

    Understanding forest carbon budget and dynamics for sustainable resource management and ecosystem functions requires quantification of above- and below-ground biomass at individual tree species and stand levels. In this study, a total of 122 trees (9-12 per species) were destructively sampled to determine above- and below-ground biomass of 12 tree species (Acer mandshuricum, Acer mono, Betula platyphylla, Carpinus cordata, Fraxinus mandshurica, Juglans mandshurica, Maackia amurensis, P. koraiensis, Populus ussuriensis, Quercus mongolica, Tilia amurensis and Ulmus japonica) in coniferous and broadleaved mixed forests of Northeastern China, an area of the largest natural forest in the country. Biomass allocation was examined and biomass models were developed using diameter as independent variable for individual tree species and all species combined. The results showed that the largest biomass allocation of all species combined was on stems (57.1%), followed by coarse root (21.3%), branch (18.7%), and foliage (2.9%). The log-transformed model was statistically significant for all biomass components, although predicting power was higher for species-specific models than for all species combined, general biomass models, and higher for stems, roots, above-ground biomass, and total tree biomass than for branch and foliage biomass. These findings supplement the previous studies on this forest type by additional sample trees, species and locations, and support biomass research on forest carbon budget and dynamics by management activities such as thinning and harvesting in the northeastern part of China.

    Full Text Available For decades, historians defined the ukanju, also known as taoren (逃人 in the Chinese-language archives of the Qing Dynasty (1644–1911A.C., as the Manchu’s ethnic Han-Chinese slaves or escapees. However, this definition fails to explain why ukanju served as the catalyst for the Manchu invasions of Chosŏn in 1627 and 1636 and why so many ukanju with considerable ethnic diversity emerged in the first half of the 17th century. Also, the question of what roles the ukanju played in the Ming-Qing transition (1616–1644 A.C. is still unexplored. In this essay, I will redefine ukanju as, rather than merely slaves, a person or group of people who fled from their own country to another place (or crossed the borders. I will also point out the overlooked relationship between the ukanju and the transition of the political order in Northeastern Asia during the 17th century – including the reversal of outcomes in battles between the Qing and the Ming, the legal shift regarding state boundaries and the act of fleeing in the Chosŏn legal code. To achieve this goal, I will utilize Manchu archives as well as Qing and Chosŏn archives written in classical Chinese as the main sources of this essay. This study, therefore, contributes to Korean and Chinese history, international relations in pre-modern Northeastern Asia, and Manchu studies.

    Poland's accession to the European Union contributed to the infrastructure development of the whole country. One of the elements of the modernized infrastructure is the sewage network and facilities on this network, as well as facilities for waste water treatment and disposal of sludge. A wide stream of funds flowing to the country, and consequently also to the north-eastern polish voivodeships (Podlaskie, Warmian-Masurian, Lublin), allowed modernization, organize, and sometimes to build a new sewage management of this part of the country. The main factors and parameters that allow us to evaluate the development of the sewage management in north-eastern Poland are included: percentage of population using sewage treatment plants, number of municipal sewage plants with the division of their type, number of industrial plants, number of septic tanks, amount of sewage purified in a year, amount of sludge produced in the year, design capacity of sewage treatment plant, size of plant in population equivalent (PE). From a number of investments in the field of wastewater management carried out in the discussed area in the period after Poland's accession to the European Union, 9 investments were considered the most important, 3 from each of the voivodeships.

    Full Text Available Thinning trials in lowland plantations in the Veneto Region (North-eastern Italy. More than 234 hectares of new plantations of lowland mixed forest have been realized in the last 20 years in the Veneto Region (North-eastern Italy. In many of these is now needed to start thinning operations, but there is a lack of experience about this topic. Aim of this work was to undertake an experimentation on different types of thinnings. The thinning trial has been performed at Bosco San Marco forest, municipality of Cessalto (Venice, in a very dense hornbeam-oak plantation aged 16. In 2010, three different thinning types were implemented on 9 hectares according to the following layout: geometrical (34% of woody mass removed, selective (15%, mixed geometrical-selective (30%, control plot. Three years later no significant differences between thinning trials in term of diametric growth, geometrical thinning excepted, were observed. These results provide a suite of solutions to the forest manager for choosing the early thinning type in high tree density condition.

    Full Text Available Diagnostic characters of nine species of the genus Channa Scopoli of northeastern India are given. Examination of morphological and osteological characters revealed that the fish under study comprised two phylectic groups: marulius and gachua. The Marulius group is characteristic by having a very prominent V-shaped sharp isthmus, cephalic sensory pores arranged in groups, absence of scales on the lower jaw, a sharp prominent spinelike hypurapophysis, more branchial toothplates than epibranchial, and an elongated urostyle. The Gachua group is characterized by a U-shaped isthmus, cephalic sensory pores evenly arranged in a single row, the presence of one or two large cycloid scales on each side of the lower jaw, absence of a sharp prominent spine-like hypurapophysis, absence or presence of one tooth plate in the epibranchial, and absence of an elongated urostyle. An elongated bone is present in between two last hemal spines of all species examined. A key to known species of Channa of northeastern India is also given

    Full Text Available The vegetational landscape of north-eastern Terai region at the foot hills of Central Himalayas is a mosaic of grassland, old-field, wasteland, and forest ecosystems. Like many other parts of the country, this region is also infested with alien intruders which not only interfere with the growth and production of food crops but also exercise adverse effects on the biodiversity of native species. The present study attempts to catalogue the invasive alien species of the terrestrial vegetation of north-eastern Uttar Pradesh especially with reference to their habit, taxonomic position, and nativity. A total of 1135 plant species within 580 genera under 119 families are so far known to occur in the region. Of these, only 149 species within 100 genera under 41 families have been found to be invasive aliens as evident from their center of origin, past history, nature of aggregation, and invasion observed under field conditions. About 80% of these invaders have been introduced from neotropics. Out of 173 invasive plants across India, this region shares 149 species, out of which 66% of species have come from Tropical America, 14% from African continent, and the rest from other countries. A better planning in the form of early identification and reporting of infestation and spread of noxious weeds is needed for their control.

    Full Text Available This is a qualitative comparison of the distribution of macroalgal-dominated coastal detritic communities from the Western Mediterranean and the Northeastern Atlantic, based on our own data from the Balearic Islands (Western Mediterranean and available data from literature. The macroalgal-dominated coastal detritic bottoms from both regions could be distinguished by the presence of a high number of regional exclusive non-carbonated species, and the presence of a high number of maërl-forming species in the Mediterranean. Further, regional differences in the distribution of some exclusive species allowed the distinction of three zones in the Northeastern Atlantic (United Kingdom, French Brittany and Galicia, while no differences were found within the Western Mediterranean. However, the algal communities considered in the selected literature could not be qualitatively distinguished, and all the samples should be considered as maërl beds. Lithothamnion corallioides and Phymatolithon calcareum were the most widespread maërl forming species in the two regions, while in the Western Mediterranean Spongites fruticulosus was also very frequent. According to the differences in the species composition of the basal and erect strata of these beds, and also in their species richness, five different morphologies of macroalgal-dominated detritic bottoms could be distinguished. Their main characteristic species and their biogeographical distribution are detailed.

  17. Vestiges of an Ancient Border in the Contemporary Genetic Diversity of North-Eastern Europe.

    Directory of Open Access Journals (Sweden)

    Anu M Neuvonen

    Full Text Available It has previously been demonstrated that the advance of the Neolithic Revolution from the Near East through Europe was decelerated in the northernmost confines of the continent, possibly as a result of space and resource competition with lingering Mesolithic populations. Finland was among the last domains to adopt a farming lifestyle, and is characterized by substructuring in the form of a distinct genetic border dividing the northeastern and southwestern regions of the country. To explore the origins of this divergence, the geographical patterns of mitochondrial and Y-chromosomal haplogroups of Neolithic and Mesolithic ancestry were assessed in Finnish populations. The distribution of these uniparental markers revealed a northeastern bias for hunter-gatherer haplogroups, while haplogroups associated with the farming lifestyle clustered in the southwest. In addition, a correlation could be observed between more ancient mitochondrial haplogroup age and eastern concentration. These results coupled with prior archeological evidence suggest the genetic northeast/southwest division observed in contemporary Finland represents an ancient vestigial border between Mesolithic and Neolithic populations undetectable in most other regions of Europe.

    Full Text Available Poland's accession to the European Union contributed to the infrastructure development of the whole country. One of the elements of the modernized infrastructure is the sewage network and facilities on this network, as well as facilities for waste water treatment and disposal of sludge. A wide stream of funds flowing to the country, and consequently also to the north-eastern polish voivodeships (Podlaskie, Warmian-Masurian, Lublin, allowed modernization, organize, and sometimes to build a new sewage management of this part of the country. The main factors and parameters that allow us to evaluate the development of the sewage management in north-eastern Poland are included: percentage of population using sewage treatment plants, number of municipal sewage plants with the division of their type, number of industrial plants, number of septic tanks, amount of sewage purified in a year, amount of sludge produced in the year, design capacity of sewage treatment plant, size of plant in population equivalent (PE. From a number of investments in the field of wastewater management carried out in the discussed area in the period after Poland's accession to the European Union, 9 investments were considered the most important, 3 from each of the voivodeships.

  19. The seasonality of butterflies in a semi-evergreen forest: Gibbon Wildlife Sanctuary, Assam, northeastern India

    Full Text Available A study spanning 3.7 years on the butterflies of Gibbon Wildlife Sanctuary GWS (21km2, a semi-evergreen forest, in Jorhat District of Assam, northeastern India revealed 211 species of butterflies belonging to 115 genera including 19 papilionids and seven ‘rare’ and ‘very rare’ species as per Evans list of the Indian sub-continent (Great Blue Mime Papilio paradoxa telearchus; Brown Forest BobScobura woolletti; Snowy Angle Darpa pteria dealbatahas; Constable Dichorragia nesimachus; Grey Baron Euthalia anosia anosia; Sylhet Oakblue Arhopala silhetensis; Branded Yamfly Yasoda tripunctata. The butterflies showed a strong seasonality pattern in this forest with only one significant peak during the post monsoon (September-October when 118 species were in flight inside the forest which slowly declined to 92 species in November-December. Another peak (102 species was visible after winter from March to April. Species composition showed least similarity between pre-monsoon (March-May and post-monsoon (October-November seasons. The number of papilionid species were greater from July to December as compared from January to June. The findings of this study suggest that the pattern of seasonality in a semi-evergreen forest in northeastern India is distinct from that of the sub-tropical lowland forest in the Himalaya. Favourable logistics and rich diversity in GWS points to its rich potential in promoting ‘butterfly inclusive ecotourism’ in this remnant forest.

  20. Composition and carbon dynamics of forests in northeastern North America in a future, warmer world

    This article provided a synthesis of modelling and scientific DNA which indicated that tree migrations since the last glaciation period were slower than current and predicted climatic warming trends. Air pollution is now offsetting carbon dioxide (CO 2 ) gains in biomass and will predispose many trees to other stresses. Nitrogen and sulfate deposition in the northeastern United States is changing forest nutrient availability, and is reducing the reproductive success and frost hardiness of some species. Acid deposition is also causing physical damage to leaves and changing the behaviour of pests and diseases. It is expected that the interacting stresses will cause declines in tree populations as well as ecosystem disturbances during the transition to warmer climates. Modelling studies have predicted that the warmer climates will increase habitats for most tree species in the northeastern United States. Species with declining habitats in the United States and Canada may migrate northwards. Paleo-ecological studies suggest that local edaphic factors will negatively impact current and future recruitment successes, but may also combine with climatic effect to cause sudden large shifts in vegetation. 83 refs., 2 tabs., 3 figs

    1998-01-01

    A case of pulmonary coccidioidomycosis from the rural zone of Bertolinia, PI, is reported. The patient, a farm worker, attributed his illness to the dust inhaled while digging a water well during the dry season of the year, some weeks before the onset of the clinical manifestations. The main symptoms of the disease were severe chest pain and moderate fever. The diagnosis was made histopathologically: tissue phase fungal organisms--immature spherules and spherules with endospores--were observed in histological sections of a lung fragment obtained by open chest biopsy. This is the twelfth autochthonous case of coccidioidomycosis found so far in Brazil. All of them involved native inhabitants of the semi-arid part of Northeastern Brazil. The hot and dry environment of the region seems to favor the development of C. immitis in the soil. Humans and animals probably acquire the infection by digging the soil, when they become exposed to the conidium-bearing dust raised by this activity.

    In northeastern Italy, according to Italian legislation, authorized public facilities can accept the donation and preservation of cord blood stem cells (CB-SC). Attitudes and knowledge in pregnant women differs between the local and immigrant (non-European Union [EU]) population. In this study we assessed the choices that pregnant women have with respect to the public and private harvesting system and the main reasons driving their decisions. We examined the ethnic origin of the families and compared tests for syphilis screening and leukocyte (WBC) counts in the CB-SC bags that are required for validation of the collection. Out of a population of 3450 pregnant patients at the Institute for Maternal and Child Health of Trieste, northeast Italy, 772 women agreed to cord blood harvesting and the associated lab tests. Of these, 221 women (28.6%) were from immigrant families of non-EU countries. Their ethnic affiliation was recorded, and tests were performed for syphilis screening and for nucleated red blood cell (NRBC) interference with the WBC count in CB-SC bags to assess cellularity and to determine if storage was appropriate. Of the 772 pregnant women, 648 (84.0%) accessed the public collection system, which is free of charge, and 124 (15.0%) accessed the private fee-based system. One woman from the non-EU group opted for the private fee-based system. Of the 3450 pregnant women screened for syphilis at the Institute for Maternal and Child Health, the Treponema pallidum hemagglutination (TPHA) and Venereal Disease Research Laboratory (VDRL) tests were the main tests performed (66.0% of total cases) because many gynecologists in the public harvesting system apply the Italian regulations of the 1988 Decree, while the private system requires tests on syphilis and leaves the option to the lab physicians to select the best determination method. We found that the chemiluminescence method was more specific (97.0%) than the TPHA (83.0%) and nontreponemal rapid plasma reagin

  9. Earthquake Clusters and Spatio-temporal Migration of earthquakes in Northeastern Tibetan Plateau: a Finite Element Modeling

    2017-12-01

    Seismicity in a region is usually characterized by earthquake clusters and earthquake migration along its major fault zones. However, we do not fully understand why and how earthquake clusters and spatio-temporal migration of earthquakes occur. The northeastern Tibetan Plateau is a good example for us to investigate these problems. In this study, we construct and use a three-dimensional viscoelastoplastic finite-element model to simulate earthquake cycles and spatio-temporal migration of earthquakes along major fault zones in northeastern Tibetan Plateau. We calculate stress evolution and fault interactions, and explore effects of topographic loading and viscosity of middle-lower crust and upper mantle on model results. Model results show that earthquakes and fault interactions increase Coulomb stress on the neighboring faults or segments, accelerating the future earthquakes in this region. Thus, earthquakes occur sequentially in a short time, leading to regional earthquake clusters. Through long-term evolution, stresses on some seismogenic faults, which are far apart, may almost simultaneously reach the critical state of fault failure, probably also leading to regional earthquake clusters and earthquake migration. Based on our model synthetic seismic catalog and paleoseismic data, we analyze probability of earthquake migration between major faults in northeastern Tibetan Plateau. We find that following the 1920 M 8.5 Haiyuan earthquake and the 1927 M 8.0 Gulang earthquake, the next big event (M≥7) in northeastern Tibetan Plateau would be most likely to occur on the Haiyuan fault.
