    In order to determine the influence of the ocean and atmospheric coupling dynamics on upwelling events, caused by Ekman's transport and by continental winds, as well as the possible fertilization effect produced by the increasing of the concentration of inorganic nutrients in coastal waters of Gaira's inlet, Magdalena department, during the minor dry season of 2006, atmospheric, oceanographic, and biological variables were measured by the implementation of the Eurelian method. A total of four samplings were carried out, among which two presented atmospheric and oceanic conditions that evidence the occurrence of upwelling events 48 hours before in response to strong winds coming from northeast (trade winds) and from the continent, whereas the other two samplings presented similar characteristics to those typical of rainy seasons. During this study, wind velocity and direction presented expected values during upwelling events caused by Ekman's transport and by continental winds (≥ 4.5 m/s, 26 Celsius degrade and 120 Celsius degrade, respectively), generating enough stress levels in the sea surface layer that could move it offshore (1.2 dynes/cm 2 ). During the days following the upwelling events, anomalies in water physical and chemical characteristics were observed, presenting low temperatures (26.1 +- 1.1 Celsius degrade), high salinity (36.0 +- 0.5) and, as a consequence, high densities (δ 26.31 +- 0.50), as well as low dissolved oxygen levels (4.04 +- 0.29 mL/L) and predominant subsaturation (84.3 +- 6.1 %) Inorganic nutrient concentration showed a relatively homogeneous behavior, keeping low nitrite (0.35 +- 0.02 μM) and phosphate (0.30 +- 0.01 μM) levels during all samplings, whereas the mean ammonium concentration was relatively high (1.08 +- 0.11 μM). In contrast, nitrate levels were high during all samplings, with higher values corresponding to upwelling events (9.48 +- 0.49 μM), although variation was not statistically significative.

    Full Text Available ABSTRACT To quantify the percentage of unburnt coal in beach sediments from the department of Magdalena,(Colombia a simple procedure was devised to separate the sediment mineral phases according to their density. Sediments were collected from six beaches, at two tidal heights, in November 2012 and February 2013, before and after a spill from a coal barge that occurred on 12 January 2013. Sediments were dried, suspended in an aqueous solution of sodium polytungstate (density: 2.0 g•cm-3 and centrifuged. Because coal has a lower density (1.2-1.9 g•cm-3 than other inorganic minerals and rocks, any coal particle present in a sample concentrated in the suspended fraction, whereas more dense particles settled. To remove organic matter not corresponding to coal, the light fraction was subsequently subjected to a weak oxidation with hydrogen peroxide. To estimate an upper limit for any coal present, weight loss on ignition at 550 °C was determined for whole sediments. For the six beaches examined, the maximum weight loss on ignition was 2.4 % and the weight percentage of the light fraction (with a density 3 g•cm-3, which comprise between 10-70 % of the total sediment dry weight. RESUMEN Con el fin de cuantificar el porcentaje de carbón mineral en playas del departamento del Magdalena, (Colombia se llevó a cabo un procedimiento sencillo para separar el sedimento en fracciones sedimentológicas de acuerdo a su densidad.

    The banana tree production in Colombia constitutes an important line of the economy of the country; it participates actively in the generation of foreign currencies for the high export volumes. However, in the production process, exist a series of inconveniences that if they are not managed appropriately they can affect the production directly. One of those problems is the fertilization of the plantations, the appropriate handling of the soils and the fertilization plans. With the objective of establishing the nutritional state of the soils of the banana area of the Magdalena, was carried out the present study with the purpose of determining the percentage distribution of the soils inside the different ranges of nutritious elements. Equally, with the analysis it could settle down the faulty elements in those soils and the importance of incorporating them appropriately in the fertilization plans

    Full Text Available The appropriate management of minor head injury (MHI in patients receiving oral anticoagulant (OAC is unclear. In this retrospective study, we focused on elderly patients (>65 years treated with OAC, presented to our emergency department with MHI between 2004 and 2010. Three hundred and six patients with MHI were taking OAC: we documented 7.19% hemorrhages at the first computed tomography (C; 18.19% deaths; 50.1% spontaneous reabsorptions; 22.73% deteriorations of intracranial bleeding without surgical intervention (for clinical comorbidity, and 4.55% neurosurgical interventions. We documented a second positive CT scan in 2 patients (1.51% who had no symptoms and remained asymptomatic during observation. In both cases, intracranial bleeding resolved spontaneously. The mean international normalized ratio (INR value was 2.26, higher in the group of patients with bleeding (2.74 than in the group without bleeding (2.19. We found a significant increased risk in patients with posttraumatic loss of consciousness [odds ratio (OR 28.3], diffuse headache (OR 14.79, vomiting (OR 14.2 and neurological signs (OR 5.27. We did not reach significance in patients with post-traumatic amnesia. Our data confirm the need for a CT scan of any patients on OAC with MHI. None of our patients developed any symptoms or signs during observation, and only 2 patients developed an intracranial hemorrhage in the second CT scan with a favorable evolution. Our data need to be confirmed with an observational study, but we suggest that the second CT could be reserved for patients developing symptoms and signs during observation. We also underline the role of the INR in the stratification of risk.

    The purpose of this study was to identify those particular aspects of US Department of Energy (DOE) research participation programs for undergraduate and graduate students that are most associated with attracting and benefiting underrepresented minority students and encouraging them to pursue careers in science, engineering, and technology. A survey of selected former underrepresented minority participants, focus group analysis, and critical incident analysis serve as the data sources for this report. Data collected from underrepresented minority participants indicate that concerns expressed and suggestions made for conducting student research programs at DOE contractor facilities are not remarkably different from those made by all participants involved in such student research participation programs. With the exception of specific suggestions regarding recruitment, the findings summarized in this report can be interpreted to apply to all student research participants in DOE national laboratories. Clearly defined assignments, a close mentor-student association, good communication, and an opportunity to interact with other participants and staff are those characteristics that enhance any educational program and have positive impacts on career development.

    Hydrological distributed modeling is key point for a comprehensive assessment of the feedback between the dynamics of the hydrological cycle, climate conditions and land use. Such modeling results are markedly relevant in the fields of water resources management, natural hazards and oil and gas industry. Here, we employ TopModel (TOPography based hydrological MODEL) for the hydrological modeling of an area in the Middle Magdalena Valley (MMV), a tropical basin located in Colombia. This study is located over the intertropical convergence zone and is characterized by special meteorological conditions, with fast water fluxes over the year. It has been subject to significant land use changes, as a result of intense economical activities, i.e., and agriculture, energy and oil & gas production. The model employees a record of 12 years of daily precipitation and evapotranspiration data as inputs. Streamflow data monitored across the same time frame are used for model calibration. The latter is performed by considering data from 2000 to 2008. Model validation then relies on observations from 2009 to 2012. The robustness of our analyses is based on the Nash-Sutcliffe coefficient (values of this metric being 0.62 and 0.53, respectively for model calibration and validation). Our results reveal high water storage capacity in the soil, and a marked subsurface runoff, consistent with the characteristics of the soil types in the regions. A significant influence on runoff response of the basin to topographical factors represented in the model is evidenced. Our calibrated model provides relevant indications about recharge in the region, which is important to quantify the interaction between surface water and groundwater, specially during the dry season, which is more relevant in climate-change and climate-variability scenarios.

    Two teachers from the town of San Pedro de Atacama, in the northern desert of the South American nation of Chile, arrive in Magdalena, New Mexico, Sunday, January 28, for a two-week visit that is part of a Sister Cities program sponsored by Associated Universities, Inc. (AUI), the nonprofit research corporation that operates the National Radio Astronomy Observatory (NRAO). They will be accompanied by their town's mayor. Myriam Nancy Rivera Mercado, Head of the high school in San Pedro, Gabriela Fernanda Rodriguez Moraleda, a tourism teacher there, and San Pedro Mayor Sandra Berna Martinez will begin a visit that includes classroom observations in the Magdalena schools, a reception hosted by the Magdalena Village Council, and a Mayor's Breakfast with Magdalena Mayor Jim Wolfe. They also will meet local residents, tour the Bosque del Apache National Wildlife Refuge with a second-grade class, visit an area ranch, tour the Very Large Array (VLA) radio telescope, and see Socorro's Community Arts Party. "These teachers will learn much about New Mexico, the United States, and our educational system, and will take this new knowledge back to their students and their community," said NRAO Education Officer Robyn Harrison. The visit is part of a Sister Cities program initiated and funded by AUI, which operates the NRAO for the U.S. National Science Foundation. Radio astronomy is a common link between San Pedro de Atacama and Magdalena. San Pedro is near the site of the Atacama Large Millimeter/submillimeter Array (ALMA), an international telescope project now under construction with funding by major partners in North America, Europe, and Japan. Magdalena is near the site of NRAO's VLA radio telescope. In Magdalena, the Village Council and Mayor Wolfe formalized their participation in the Sister Cities program last September, and San Pedro ratified the program in December. In San Pedro, the ceremony ratifying the agreement was attended by U.S. Ambassador to Chile Craig K

    Over 5 million children attend the Emergency Department (ED) annually in England with an ever-increasing paediatric emergency caseload echoed globally. Approximately 60% of children present with illness and the majority have non-urgent illness creating burgeoning pressures on children's ED and this crisis resonates globally. To date no qualitative systematic review exists that focuses on the parental reasons for childhood attendance at the ED in this sub-group. To identify parental reasons for attending ED for their children presenting with minor illness. A qualitative systematic review was conducted against inclusion/exclusion criteria. Five electronic databases and key journals were searched in June 2015. 471 studies were identified and following study selection, 4 qualitative studies were included. Nine themes were identified e.g. dissatisfaction with family medical services, perceived advantages of ED and 'child suffering' with novel and insightful sub-themes of 'hereditary anxiety', 'taking it off our hands', ED as a 'magical place'. This novel qualitative systematic review examined parental attendance presenting with childhood minor illness of interest to emergency care reformers and clinicians. ED attendance is complex and multifactorial but parents provide vital insight to ED reformers on parental reasons for ED attendance in this sub-group. Copyright © 2017 Elsevier Ltd.

    Among children with asthma, black children are two to four times as likely to have an emergency department (ED) visit and die from asthma, respectively, compared to white children in the United States. Despite the availability of evidence-based asthma management guidelines, minority children are less likely than white children to receive or use effective options for asthma care. The CHICAGO Plan is a three-arm multi-center randomized pragmatic trial of children 5 to 11years old presenting to the ED with uncontrolled asthma that compares: [1] an ED-focused intervention to improve the quality of care on discharge to home, [2] the same ED-focused intervention together with a home-based community health worker (CHW)-led intervention, and [3] enhanced usual care. All children receive spacers for the metered dose inhaler and teaching about its use. The Patient-Reported Outcomes Measurement Information System (PROMIS) Asthma Impact Scale and Satisfaction with Participation in Social Roles at 6months are the primary outcomes in children and in caregivers, respectively. Other patient-reported outcomes and indicators of healthcare utilization are assessed as secondary outcomes. Innovative features of the CHICAGO Plan include early and continuous engagement of children, caregivers, the Chicago Department of Public Health, and other stakeholders to inform the design and implementation of the study and a shared research infrastructure to coordinate study activities. The objective of this report is to describe the development of the CHICAGO Plan, including the methods and rationale for engaging stakeholders, the shared research infrastructure, and other features of the pragmatic clinical trial design.

    The main objective of this study was to evaluate the feasibility of emergency department (ED) point-of-care ultrasound (PoCUS) for rib fracture diagnosis in patients with minor thoracic injury (mTI). Secondary objectives were to 1) evaluate patients' pain during the PoCUS procedure, 2) identify the limitations of the use of PoCUS technique, and 3) compare the diagnosis obtained with PoCUS to radiography results. Adult patients who presented with clinical suspicion of rib fractures after mTI were included. All patients underwent PoCUS performed by emergency physicians (EPs) prior to a rib view X-ray. A visual analogue scale (VAS) ranging from 0 to 100 was used to ascertain feasibility, patients' pain and clinicians' degree of certitude. Feasibility was defined as a score of more than 50 on the VAS. We documented the radiologists' interpretation of rib view X-ray. Radiologists were blinded to the PoCUS results. Ninety-six patients were included. A majority (65%) of EPs concluded that the PoCUS technique to diagnose rib fracture was feasible (VAS score > 50). Median score for feasibility was 63. Median score was 31 (Interquartile range [IQR] 5-57) for patients' pain related to the PoCUS. The main limiting factor of the PoCUS technique was pain during patient examination (15%). PoCUS examination appears to be a feasible technique for a rib fracture diagnosis in the ED.

    1997-01-01

    The chemical composition of 25 crude oils from Tertiary reservoirs and 12 rock extracts from five organic-rich Cretaceous formations in the middle Magdalena Basin, Colombia were studied in detail by geochemical methods in order to understand their genetic relationships. The oils have been geochemically classified into four main groups based on the sulfur content, pristane/phytane, dibenzothiophene /phenanthrene, concentrations of oleanane and terpane distributions. Each group occurs in different geographic locations. Oils were mainly derived from calcareous, siliciclastic and mixture of these two facies of the Upper Cretaceous La Luna Formation. Source-oil correlation is supported by sterane and terpane distributions of and carbon isotope ratios. Some oils in the eastern margin contain relatively higher concentrations of higher plant indicators than the remaining oil samples. The molecular compositions of the oils observed in this study appear to be consistent with the inferred depositional sequence of anoxic marine/pelagic carbonate facies in the north/western sector of the Middle Magdalena, while the eastern sector received a higher proportion of clastic input. This documentation supports the interpretation that the Middle Magdalena oils have been generated 'locally', as opposed to have migrated from the region of the Eastern Cordillera. Biomarker maturity parameters indicate that the majority of oils were generated in the early thermal maturity oil window except the Colorado-38 oil, which was generated in the middle thermal maturity oil window. Oil maturity data also supports the short migration distances of oils from the early-mature source rocks to the reservoir rocks. The composition of some oils (e.g., La Cira, Infantas, Conde and Bonanza) is unusual in that gas chromatographic data contains an n-alkane and isoprenoid distribution normally associated with moderately degraded oils, but they also contain a relatively high abundance of gasoline hydrocarbons

    Of the currently published clinical decision rules for the management of minor head injury (MHI) in children, the Pediatric Emergency Care Applied Research Network (PECARN) rule, derived and validated in a large multicenter prospective study cohort, with high methodologic standards, appears to be the best clinical decision rule to accurately identify children at very low risk of clinically important traumatic brain injuries (ciTBI) in the pediatric emergency department (PED). This study describes the implementation of an adapted version of the PECARN rule in a tertiary care academic PED in Italy and evaluates implementation success, in terms of medical staff adherence and satisfaction, as well as its effects on clinical practice. The adapted PECARN decision rule algorithms for children (one for those younger than 2 years and one for those older than 2 years) were actively implemented in the PED of Padova, Italy, for a 6-month testing period. Adherence and satisfaction of medical staff to the new rule were calculated. Data from 356 visits for MHI during PECARN rule implementation and those of 288 patients attending the PED for MHI in the previous 6 months were compared for changes in computed tomography (CT) scan rate, ciTBI rate (defined as death, neurosurgery, intubation for longer than 24 hours, or hospital admission at least for two nights associated with TBI) and return visits for symptoms or signs potentially related to MHI. The safety and efficacy of the adapted PECARN rule in clinical practice were also calculated. Adherence to the adapted PECARN rule was 93.5%. The percentage of medical staff satisfied with the new rule, in terms of usefulness and ease of use for rapid decision-making, was significantly higher (96% vs. 51%, puse of the adapted PECARN rule in clinical practice was 100% (95% CI=36.8 to 100; three of three patients with ciTBI who received CT scan at first evaluation), while efficacy was 92.3% (95% CI=89 to 95; 326 of 353 patients without ci

    For analyzing basic marine and coastal characteristics we selected the potential sites where shrimp culture could be developed in a large coastal zone, Bahia Magdalena, Baja California Sur, Mexico. Based on our analysis, 6 sites were preselected and field stages of work were then developed to assess the precise suitability of each site in order to develop the proposed aquaculture activities. In ranking the suitability we were able to recommend the most appropriate places to develop shrimp culture in this region. Also, knowing the exact biological, physico-chemical and social environment, we determined the best species to cultivate, the recommended total area and the methodology to be used to lessen the environmental impact and to obtain the maximum profitability Our methodology could be used not only to select appropriate sites for shrimp culture in other coastal lagoons, but it also could be applied to assess the suitability in a quick and accurate way, of any other production activity in coastal zones.

    During night and on weekends, in our emergency department there is no radiologist on duty or on call: thus, X-ray examinations (XR) are evaluated by the orthopaedic surgeon on duty and reported the following morning/monday by radiologists. The aim of our study was to examine the discrepancy rate between orthopaedists and radiologists in the interpretation of imaging examinations performed on patients in our tertiary level orthopaedic institution and the consequences of delayed diagnosis in terms of patient management and therapeutic strategy. We retrospectively reviewed all cases of discrepancy between orthopaedists and radiologists, which were categorized according to anatomical location of injury, initial diagnosis and treatment, change in diagnosis and treatment. We used the Chi square test to compare the frequencies of discrepancies between patients ≤14 and >14years of age. From January to December 2016, 19,512 patients admitted to our emergency department performed at least an imaging examination; among these patients, 13,561 underwent XR in absence of an attending radiologist. A discrepant diagnosis was found in 337/13,561 (2.5%; 184 males; mean age: 36.7±23.7, range 2-95); 151/337 (45%) discrepancies were encountered in the lower limbs, with ankle being the most common site of misdiagnosis (64/151), and 103/337 (30%) in the upper limbs, with the elbow being the most frequent site in this district (35/103). We found 293/337 false negatives (87%) and 44/337 false positives (13%), with 134 and 13 patients needing treatment change, respectively. We found 85/337 discrepancies (25%) in patients ≤14 years of age, and 252/337 (75%) in those >14years. The distribution of discrepancies per anatomic district was significantly different (P<0.001) in these two groups of patients. A low rate of discrepancy between orthopaedists and radiologists in evaluating images of patients admitted to our emergency department was found, although treatment change occurred in about

    In the Upper Magdalena Valley, Colombia, four petroleum systems were identified. Two petroleum systems are located in the Girardot sub-basin and the other two in the Neiva sub- basin. Limestones laterally changing to shales of the lower part of the Villeta Gp, deposited during Albian and Turonian marine flooding events, constitutes the main source rocks of the oil families. These rocks contain 1-4% TOC and type II kerogen. The littoral quartz arenites of the Caballos (Albian) and Monserrate (Maastrichtian) Fms. are the main reservoir rocks. Seal rocks are Cretaceous and Paleocene shales. Overburden includes the Cretaceous rocks and the Tertiary molasse deposited simultaneously with development of two opposite verging thrust systems during Cenozoic time. These deformation events were responsible for trap creation. Except for the Villarrica area, where the source rock reached maturity during the Paleocene, generation occurred during Miocene. Two oil families are identified, each in both sub-basins: One derived from a clay-rich source and the second from a carbonate-rich source rock lithofacies of the lower part of Villeta Gp. Geochemical source-rock to oil correlations are demonstrated for the three of the petroleum systems. Up-dip lateral migration distances are relatively short and faults served as vertical migration pathways. A huge amount of oil was probably degraded at surface, as a result of Miocene deformation and erosion. (author)

    A local Magnitude (ML) scale for Valle Medio del Magdalena (VMM) region was defined by using 514 high quality earthquakes located at VMM area and inversion of 2797 amplitude values of horizontal components of 17 stations seismic broad band stations, simulated in a Wood-Anderson seismograph. The derived local magnitude scale for VMM region was: ML =log(A) + 1.3744 ∗ log(r) + 0.0014776 ∗ r - 2.397 + S Where A is the zero-to-peak amplitude in nm in horizontal components, r is the hypocentral distance in km, and S is the station correction. Higher values of ML were obtained for VMM region compared with those obtained with the current formula used for ML determination, and with California formula. With this new scale ML values are adjusted to local conditions beneath VMM region leading to more realistic ML values. Moreover, with this new ML scale the seismicity caused by tectonic or fracking activity at VMM region can be monitored more accurately.

    Full Text Available The Magdalena River is the most important river in Colombia in terms of economic activities and is home to about 77% of the country’s population. The river faces water resources allocation challenges, which require reliable hydrological assessments. However, hydrological analysis and model simulations are hampered by insufficient and uncertain knowledge of the actual rainfall fields. In this research the reliability of groundbased measurements, different satellite products of rainfall and their combinations are tested for their impact on the discharge simulations of the Magdalena River. Two different satellite rainfall products from the Tropical Rainfall Measuring Mission (TRMM, have been compared and merged with the ground-based measurements and their impact on the Magdalena river flows quantified using the Representative Elementary Watershed (REW distributed hydrological model.

    Forty two samples were acquired from the surface and bottom water profiles along 5 transects spread over Bahia Magdalena lagoon, Baja California Sur to assess the behavior of trace metals in a high influenced upwelling region on the Pacific coast. To elaborate the fate of metals, also the physico-chemical parameters (pH, temperature, salinity, conductivity, dissolved oxygen). Determination of the concentrations of trace metals (Fe, Mn, Cr, Cu, Co, Pb, Ni, Zn, Cd As, Hg) were measured using Atomic absorption spectrometry. The results demonstrated high values of As, Ni and Co which is attributed to the local geology and phosphate deposits. Low values of Fe and Mn are attested to the oxic conditions of the lagoon which are responsible for the oxidation of Fe and Mn. The region witnesses raised temperatures (28.92ºC) and salinities of 35.2 PSU for its arid climatic conditions and high rates of evaporation. In general, the region presented minor quantities of dissolved trace metals due to dispersion and high intense interaction with the open sea. The results were also compared with other studies to understand the enrichment pattern in this side of the pacific coast which experiences various geothermal activities and upwelling phenomenon.

    Faculty diversity is a longstanding challenge in the US. However, we lack a quantitative and systemic understanding of how the career transitions into assistant professor positions of PhD scientists from underrepresented minority (URM) and well-represented (WR) racial/ethnic backgrounds compare. Between 1980 and 2013, the number of PhD graduates from URM backgrounds increased by a factor of 9.3, compared with a 2.6-fold increase in the number of PhD graduates from WR groups. However, the number of scientists from URM backgrounds hired as assistant professors in medical school basic science departments was not related to the number of potential candidates (R2=0.12, p>0.07), whereas there was a strong correlation between these two numbers for scientists from WR backgrounds (R2=0.48, pprofessors and posited no hiring discrimination. Simulations show that, given current transition rates of scientists from URM backgrounds to faculty positions, faculty diversity would not increase significantly through the year 2080 even in the context of an exponential growth in the population of PhD graduates from URM backgrounds, or significant increases in the number of faculty positions. Instead, the simulations showed that diversity increased as more postdoctoral candidates from URM backgrounds transitioned onto the market and were hired.

    Integration of clinical decision support services (CDSS) into electronic health records (EHRs) may be integral to widespread dissemination and use of clinical prediction rules in the emergency department (ED). However, the best way to design such services to maximize their usefulness in such a complex setting is poorly understood. We conducted a multi-site cross-sectional qualitative study whose aim was to describe the sociotechnical environment in the ED to inform the design of a CDSS intervention to implement the Pediatric Emergency Care Applied Research Network (PECARN) clinical prediction rules for children with minor blunt head trauma. Informed by a sociotechnical model consisting of eight dimensions, we conducted focus groups, individual interviews and workflow observations in 11 EDs, of which 5 were located in academic medical centers and 6 were in community hospitals. A total of 126 ED clinicians, information technology specialists, and administrators participated. We clustered data into 19 categories of sociotechnical factors through a process of thematic analysis and subsequently organized the categories into a sociotechnical matrix consisting of three high-level sociotechnical dimensions (workflow and communication, organizational factors, human factors) and three themes (interdisciplinary assessment processes, clinical practices related to prediction rules, EHR as a decision support tool). Design challenges that emerged from the analysis included the need to use structured data fields to support data capture and re-use while maintaining efficient care processes, supporting interdisciplinary communication, and facilitating family-clinician interaction for decision-making.

    Large studies which developed decision rules for the use of Computed tomography (CT) in children with minor head trauma excluded children with late presentation (more than 24h). To assess the prevalence of significant traumatic brain injury (TBI) on CT in infants with head trauma presenting to the emergency department (ED) more than 24h from the injury. A retrospective chart review of infants less than 24 months old referred for head CT because of traumatic brain injury from January 2004 to December 2014 in Assaf-Harofeh medical center was conducted. We used the PECARN definitions of TBI on CT to define significant CT findings. 344 cases were analyzed, 68 with late presentation. There was no significant difference in the age between children with late and early presentation (mean 11.4 (SD 5.6) month vs 10. 5 (SD 7.0) month, P=0.27). There was no significant difference between the groups in the incidence of significant TBI (22% vs 19%, p=0.61). Any TBI on CT (e.g. fracture) was found in 43 (63%) patients with late presentation compared with 116 (42%) patients with early presentation (p=0.002, OR 2.37, 95% CI 1.37-4.1). A similar rate of CT-identified traumatic brain injury was detected in both groups.‏ There was no significant difference in the incidence of significant TBI on CT between the groups.‏ Young children presenting to the ED more than 24 hours after the injury may have abnormal findings on CT.

    2018-02-01

    Fluxes of continental runoff and sediments as well as downstream deposition of eroded soils have severely altered the structure and function of fluvial and deltaic-estuarine ecosystems. The Magdalena River, the main contributor of continental fluxes into the Caribbean Sea, delivers important amounts of water and sediments into Cartagena Bay, a major estuarine system in northern Colombia. Until now, trends in fluvial fluxes into the bay, as well as the relationship between these tendencies in fluvial inputs and associated upstream changes in the Magdalena catchment, have not been studied. Here we explore the interannual trends of water discharge and sediment load flowing from the Magdalena River-Canal del Dique system into Cartagena Bay during the last three decades, forecast future scenarios of fluxes into the bay, and discuss possible connections between observed trends in fluvial inputs and trends in human intervention in the Magdalena River basin. Significant upward trends in annual runoff and sediment load during the mid-1980s, 1990s, and post-2000 are observed in the Magdalena and in the Canal del Dique flowing into Cartagena Bay. During the last decade, Magdalena streamflow and sediment load experienced increases of 24% and 33%, respectively, compared to the pre-2000 year period. Meanwhile, the Canal del Dique witnessed increases in water discharge and sediment load of 28% and 48%, respectively. During 26 y of monitoring, the Canal del Dique has discharged 177 Mt of sediment to the coastal zone, of which 52 Mt was discharged into Cartagena Bay. Currently, the Canal drains 6.5% and transports 5.1% of the Magdalena water discharge and sediment load. By 2020, water discharge and sediment flux from the Canal del Dique flowing to the coastal zone will witness increments of 164% and 260%, respectively. Consequently, sediment fluxes into Cartagena Bay will witness increments as high as 8.2 Mt y- 1 or 317%. Further analyses of upstream sediment load series for 21

    The Magdalena River is the most important river in Colombia, supplying over 70% of the population of fish and drinking water, and it also is the main river transportation way of the country. It receives effluents from multiple sources along its course such as contaminant agricultural and industrial discharges. To evaluate the toxicity profile of Magdalena River sediments through endpoints such as survival, locomotion, and growth, wild type strains of Caenorhabditis elegans were exposed to aqueous extracts of the sediments. To identify changes in gene expression, GFP transgenic strains were used as reporter genes. Physiological and biochemical data were correlated with metal concentration in the sediments, identifying patterns of toxicity along the course of the river. Levels of some metals such as Cd, Cu, and Ni were above TEC and PEC limits. Effects in survival, growth, and locomotion were observed in most of the samples, and changes in gene expression were evident in the genes mtl-2, sod-4, and gst-1 using fluorescence expression. Cadmium and lead were the metals which were primarily associated with sediment toxicity, and the sampling sites with the highest increased expression of stress response genes were Barrancabermeja and Girardot. However, the diverse nature of toxic profiles observed in C. elegans in the study area showed the pervasiveness of different types of discharges throughout the river system. - Highlights: • The Magdalena River has high levels of some metals such as Cd, Cu, and Ni. • Most sediment extracts affected lethality, growth, and locomotion of C. elegans. • Sediment extracts induced expression changes in mtl-2, sod-4, and gst-1. • Sediment toxicity was primarily associated with Cd and Pb. • Highest toxicity was observed for samples collected in mining and industrial areas. - In Magdalena River sediments, Cd and Pb were associated with toxicity in Caenorhabditis elegans and expression of stress response genes were related to

    This study explores the application of an empirical sediment flux model BQART, to simulate long-term sediment fluxes of major tributaries of a river system based on a limited number of input parameters. We validate model results against data of the 1612 km long Magdalena River, Colombia, South America, which is well monitored. The Magdalena River, draining a hinterland area of 257,438 km2, of which the majority lies in the Andes before reaching the Atlantic coast, is known for its high sediment yield, 560 t kg- 2 yr-1; higher than nearby South American rivers like the Amazon or the Orinoco River. Sediment fluxes of 32 tributary basins of the Magdalena River were simulated based on the following controlling factors: geomorphic influences (tributary-basin area and relief) derived from high-resolution Shuttle Radar Topography Mission data, tributary basin-integrated lithology based on GIS analysis of lithology data, 30year temperature data, and observed monthly mean discharge data records (varying in record length of 15 to 60 years). Preliminary results indicate that the simulated sediment flux of all 32 tributaries matches the observational record, given the observational error and the annual variability. These simulations did not take human influences into account yet, which often increases sediment fluxes by accelerating erosion, especially in steep mountainous area similar to the Magdalena. Simulations indicate that, with relatively few input parameters, mostly derived from remotely-sensed data or existing compiled GIS datasets, it is possible to predict: which tributaries in an arbitrary river drainage produce relatively high contributions to sediment yields, and where in the drainage basin you might expect conveyance loss.

    Full Text Available El río Magdalena fue por siglos la principal y casi obligada vía de comunicación desde el interior de Colombia con el Caribe y el mundo, a pesar de que su navegación siempre fue difícil como se muestra en este artículo, basado en testimonios de viaje y otras fuentes. Las dificultades, atribuibles a causas naturales como lo empinado y erosionable de la cuenca, que propician formación de bancos de arena y mucho torrencial, se agravan luego por la deforestación. La navegación colapsará finalmente, por esta y otras causas, en la década de 1960. Pero ya desde el siglo XVIII se exploraban alternativas de transporte que se encontrarán en la salida al Pacífico, mediante ferrocarriles y carreteras empezadas terminando el siglo XIX. Las nuevas vías, y la apertura del Canal de Panamá en 1914, impulsarán el desarrollo de Cali, Buenaventura y del occidente del país, en detrimento del Caribe y especialmente de Barranquilla que, a través del Magdalena, habían sido eje del comercio exterior colombiano. Evidencia científica explica las dificultades naturales; luego, un panorama de la deforestación explica su agravamiento. Actualmente hay proyectos ambiciosos para devolver navegabilidad al río, en un proceso riesgoso donde parece importante recordar que el Magdalena siempre fue un río difícil.

    El río Magdalena fue por siglos la principal y casi obligada vía de comunicación desde el interior de Colombia con el Caribe y el mundo, a pesar de que su navegación siempre fue difícil como se muestra en este artículo, basado en testimonios de viaje y otras fuentes. Las dificultades, atribuibles a causas naturales como lo empinado y erosionable de la cuenca, que propician formación de bancos de arena y mucho torrencial, se agravan luego por la deforestación...

    In order to assess the potential effects of the Magdalena River recommunication with its former delta, we studied the abundance and composition of the rotiferofauna of the Pajarales Complex (PC) during its highest annual zooplankton abundance. We selected the Rotifera phylum, due to its high reproductive rates and the efficiency in energetic transformation process. We sampled the rotifers with a van Dorn bottle, during the second rainy season in 2006. During each sampling we registered salinity, temperature, pH, and dissolved oxygen. We calculated the rotifer diversity using the Shannon-Wiener H (log10) index comparing among sampling sites and sampling dates to establish variations along the study period. The physico-chemical variables were graphically related with the diversity values calculated using 0.05 for ??and 95% for the confidence interval. We found a total of 20 morpho types belonged to Brachionidae, Lecanidae, Filiniidae, Synchaetidae, exarthriidae and Testudinellidae families, been Brachionidae and Lecanidae the most abundant. The relationships between diversity and physico-chemical variables, show salinity as the main responsible of the rotifer diversity; in conclusion, the current rotiferofauna in the PC is most abundant and diverse than 16 years ago, before the recommunication with the Magdalena River. Likewise, dissolved oxygen concentration, pH and salinity of the CP waters were different. Taking into account that salinity was the most influent factor in the rotiferofauna diversity; the river recomommunication probably favored the increment of rotiferofauna diversity in the PC

    Full Text Available El trabajo se propone aportar elementos críticos sobre la cooperación internacional, en particular sobre la cooperación europea, en el Magdalena Medio durante la primera década del siglo XXI. Partiendo de que los flujos de capital de la cooperación internacional para el desarrollo no son políticamente neutros y están condicionadospor los intereses geopolíticos y geoeconómicos de los donantes, sostenemos que la cooperación en esta región ha contribuido a consolidar nuevas espacialidades capitalistas en favor de la acumulación global y en detrimento de las propuestas de desarrollo territorial que han construido las comunidades de esta región. Este proceso ha operado bajo distintas modalidades de acumulación por desposesión en medio de la crisis humanitaria que ha generado el desarrollo del conflicto social y armado. En el Magdalena Medio uno de los escenarios de desposesión más destacados es el de la agroindustria palmera.

    Diversity and the underrepresentation of women, African-Americans, Hispanics and American Indians in the nation's science, technology, engineering and mathematics (STEM) fields are the subjects of the XV: A View from the Gatekeepers—STEM Department Chairs at America's Top 200 Research Universities on Female and Underrepresented Minority Undergraduate STEM Students. Annual public opinion research project commissioned by Bayer Corporation, the Bayer Facts surveys examine science education and science literacy issues. The 15th in the series and the fifth to explore diversity and underrepresentation, this research is a direct outgrowth of last year's results which found 40 percent of the country's female and underrepresented minority (URM) chemists and chemical engineers working today were discouraged from pursuing their STEM career at some point in their lives. US colleges were cited as places where this discouragement most often happened and college professors as the individuals most likely responsible. Does such discouragement still occur in American colleges today? To answer this and other questions about the undergraduate environment in which today's students make their career decisions, the survey polls 413 STEM department chairs at the nation's 200 top research universities and those that produce the highest proportion of female and URM STEM graduates. The survey also asks the chairs about their institutions track record recruiting and retaining female and URM STEM undergraduates, preparedness of these students to study STEM, the impact of traditional introductory STEM courses on female and URM students and barriers these students face pursuing their STEM degrees.

  17. Managing water scarcity in the Magdalena river basin in Colombia.An economic assessment

    2014-05-01

    Key words: global change, water scarcity, river basin In Colombia, serious water conflicts began to emerge with the economic development in the 70ies and 80ies and the term "water scarcity" became a common word in this tropical country. Despite a mean annual runoff of 1840 mm, which classifies Colombia as a water rich country, shortfalls in fresh water availability have become a frequent event in the last two decades. One reason for the manifestation of water scarcity is the long-held perception of invulnerable water abundance, which has delayed technical and political developments to use water more efficiently. The Magdalena watershed is the most important and complex area in Colombia, because of its huge anthropogenic present, economic development and increasing environmental problems. This river basin has a total area of 273,459 km2, equivalent to 24% of the territory of the country. It is home to 79% of the country's population (32.5 million of inhabitants) and approximately 85% of Gross Domestic Product of Colombia is generated in this area. Since the economic development of the 1970s and 1980s, large changes in land cover and related environmental conditions have occurred in the Magdalena basin. These changes include deforestation, agricultural land expansion, soil degradation, lower groundwater and increased water pollution. To assess the consequences of geophysical alteration and economic development, we perform an integrated analysis of water demand, water supply, land use changes and possible water management strategies. The main objective of this study is to determine how global and local changes affect the balance between water supply and demand in the Magdalena river basin in Colombia, the consequences of different water pricing schemes, and the social benefits of public or private investments into various water management infrastructures. To achieve this goal, a constrained welfare maximization model has been developed. The General Algebraic Modeling

    en la parte baja de la cuenca del río Magdalena y en la cuenca del río San Jorge, Colombia, en donde cada vez su comercialización cobra fuerza debido al desplazamiento y disminución en los volúmenes de captura de otras especies como el bagre rayado y bocachico. Lo cual ha llevado a la comúnmente llamada pacora a catalogarse en estado de vulnerabilidad en las cuencas colombianas. Lo anterior, hace necesario la generación de información que sirva de sustento a programas de conservación y uso sostenible de la especie. Una primera aproximación a las poblaciones de P. magdalenae puede ser hecha a través de marcadores moleculares microsatelitales, útiles en trabajos de genética de poblaciones, conservación y manejo de recursos biológicos. Sin embargo, la principal dificultad de los microsatélites es que deben ser aislados de novo para aquellas especies que van a ser evaluadas por primera vez, lo que lleva a la necesidad de obtener primers para la especie. En este trabajo, inicialmente se obtuvo un ADN de buena calidad útil para amplificaciones a partir de muestras de músculo colectadas en cuatro puntos de la cuenca del río San Jorge; posteriormente, se aislaron primers microsatelitales especie-específicos para P. magdalenae mediante amplificación cruzada con primers de otras especies de peces lejanas, entre las cuales se encuentra: Pseudoplatystoma corruscans, Pimelodella chagressi, Prochilodus argenteus y Prochilodus costatus. Para lo anterior, fue necesario modificar y estandarizar protocolos de amplificación mediante cambios en temperatura de alineamiento y concentración de reactivos; y por último se realizó el secuenciamiento de regiones flanqueantes y motivos de repetición en aquellos sistemas que presentaron resultados positivos, de esta forma, se diseñaron primers de regiones microsatélite para la especie. De los trece sistemas evaluados, de las cuatro especies, se obtuvo amplificación positiva de seis. Por medio de la t

    2001-01-01

    Wetlands are ecosystems with environmental and ecological importance that require of a new methodological and legal focus that allows developing conservation policies in agreement with the natural and socio-cultural conditions. In the Magdalena Medio Antioqueno, CORANTIOQUIA region, were recognized 362 wetlands, divided in two main groups; in Puerto Nare and Puerto Berrio to the south prevails herbaceous wetlands without permanent surface water, locally known as Bajos. In Yondo the wetlands have permanent surface water. The environmental dynamic depends from the geomorphologic and hydrological conditions and are affected in a differential way by the human action. The region is the result of a long occupation process that begins in prehistoric times and had changed depending on the different historical moments. This complex social configuration has given origin to diverse perceptions and types of appropriation of the wetlands what explains the identified environmental circumstances

    Full Text Available Previous research on Dengue Fever have involved laboratory tests or study areas with less diverse temperature and elevation ranges than is found in Colombia; therefore, preliminary research was needed to identify location specific attributes of Dengue Fever transmission. Environmental variables derived from the Moderate Resolution Imaging Spectroradiometer (MODIS and Tropical Rainfall Measuring Mission (TRMM satellites were combined with population variables to be statistically compared against reported cases of Dengue Fever in the Río Magdalena watershed, Colombia. Three-factor analysis models were investigated to analyze variable patterns, including a population, population density, and empirical Bayesian estimation model. Results identified varying levels of Dengue Fever transmission risk, and environmental characteristics which support, and advance, the research literature. Multiple temperature metrics, elevation, and vegetation composition were among the more contributory variables found to identify future potential outbreak locations.

    Emotional distress is common in Colombian armed conflict victims. Multiple-victimisation is associated with an increase in emotional distress than victimisation due a single event. However, the association between poly-victimisation and emotional distress among victims of the armed conflict in Colombia has not been documented. To study the association between multiple-victimisation and emotional distress in victims of armed conflict in the State of Magdalena, Colombia. A cross-sectional study was designed, with a secondary analysis of registration of the Psychosocial Care Program and Victim Integral Health (PAPSIVI) in the State of Magdalena, from 2013 to 2014. The profile formula grouped demographic variables, victimising events, and a set of symptoms of emotional distress (perceived discrimination, depressive and anxiety-stress). Odds ratio (OR, 95%CI) were established as measures of association. A total of 943 people were included, with 67.4% women, and ages between18 and 94 years (mean 47.9±14.2). A total of 109 (11.7%) suffered from multiple victimisation. Multiple victimisation events were associated with more emotional distress, depressive symptoms (OR=1.5; 95%CI, 1.3-1.8), perceived stigma (OR=1.3; 95%CI, 1.1-1.5), and anxiety-stress (OR=1.2; 95%CI 1.0-1.4) than a single event. There is more emotional distress in multiple victimisations than in a single victimisation event during armed conflict in this region of Colombia. Further studies are required on this topic.

    The Colombian Andes and its main river basin, the Magdalena, have witnessed dramatic changes in land cover and further forest loss during the last three decades. For the Magdalena River, human activities appear to have played a more prominent role compared to rainfall (climate change) to mobilize sediment. However, environmental authorities in Colombia argue that climate change is the main trigger of erosion and floods experienced during the last decade. Here we present the first regional exercise addressing the following: (1) what are the observed trends of sediment load in the northern Andes during the last three decades? and (2) are sediment load trends in agreement with tendencies in land use change and climate (e.g., precipitation)? We perform Mann-Kendall tests on sediment load series for 21 main tributary systems during the 1980-2010 period. These gauging stations represent 77% of the whole Magdalena basin area. The last decade has been a period of increased pulses in sediment transport as seen by the statistical significant trends in load. Overall, six subcatchments, representing 55% of the analyzed Magdalena basin area, have witnessed increasing trends in sediment load. Also, some major tributaries have experienced changes in their interannual mean sediment flux during the mid- 1990s and 2005. Further analysis of land cover change (e.g., deforestation) indicates that the basin has undergone considerable change. Forest cover decreased by 40% over the period of study, while the area under agriculture and pasture cover (agricultural lands 1 and 2) increased by 65%. The highest peak of forest loss on record in the Magdalena basin, 5106 km2 or 24% of the combined deforestation in Colombia, occurred during the 2005-2010 period. In contrast, Mann-Kendall tests on rainfall series for 61 stations reveal that precipitation shows no regional signs of increasing trends. Also, increasing trends in sediment load match quite well with the marked increase in forest

    The Magdalena-Cauca macrobasin covers 24% of the land area of Colombia, and provides more than half of the country's economic potential. The basin is also home a large proportion of Colombia's biodiversity. These conflicting demands have led to problems in the basin, including a dramatic fall in fish populations, additional flooding (such as the severe nationwide floods caused by the La Niña phenomenon in 2011), and habitat loss. It is generally believed that the solution to these conflicts is to manage the basin in a more integrated way, and bridge the gaps between decision-makers in different sectors and scientists. To this end, inter-ministerial agreements are being formulated and a decision support system is being developed by The Nature Conservancy Colombia. To engage stakeholders in this process SimBasin, a "serious game", has been developed. It is intended to act as a catalyst for bringing stakeholders together, an illustration of the uncertainties, relationships and feedbacks in the basin, and an accessible introduction to modelling and decision support for non-experts. During the game, groups of participants are led through a 30 year future development of the basin, during which they take decisions about the development of the basin and see the impacts on four different sectors: agriculture, hydropower, flood risk, and environment. These impacts are displayed through seven indicators, which players should try to maintain above critical thresholds. To communicate the effects of uncertainty and climate variability, players see the actual value of the indicator and also a band of possible values, so they can see if their decisions have actually reduced risk or if they just "got lucky". The game works as a layer on top of a WEAP water resources model of the basin, adapted from a basin-wide model already created, so the fictional game basin is conceptually similar to the Magdalena-Cauca basin. The game is freely available online, and new applications are being

    Due to its complex hydrological, geomorphological and climatic features, the Chilean fjords region is considered among the most productive areas of the world. The benthic fauna of this region accounts for more than 1600 species showing marked latitudinal biogeographic differences characterizing this as one of the most important hotspot of biodiversity of cold-temperate environments. Despite numerous studies have been conducted to depict the biological characteristics of the fjords, the present situation is strongly unbalanced towards specific taxa. Hence, this study takes into consideration a community approach, highlighting the distribution of six benthic assemblages thriving on vertical walls along the Seno Magdalena fjord (Aysen region). Underwater pictures were used to characterize the trends in abundance and diversity of the main taxa showing distinct responses to salinity and turbidity. Among the less tolerant taxa to high fresh water inputs there are encrusting algae, mainly found in the most external sites lashed by outer currents, far from the estuarine plume. The bathymetric zonation of the assemblages, instead, is characterized by a dense mussel belt in the first 10 m, within a thick layer of low-salinity, nutrient-enriched waters. Rich assemblages of sponges, brachiopods, gorgonians and scleractinians thrive in deeper, marine, clear waters. The evaluation of the ecological role of benthic species leads both to the definition of potential bioindicator taxa responding to anthropic disturbances and to the promotion of protected areas.

    Full Text Available Este estudio debe comenzar en el siglo XVI en las Antillas, refugio de buscadores de oro y guerreros profesionales que allí esperaron el momento de hacer el aporte europeo a nuestra formación. Otro elemento racial nos llegó en los barcos negros. Y el factor básico estuvo representado por el elemento aborigen, que mostraba grupos situados en diversas estapas de evolución. En el actual Departamento del Magdalena se destacaba la cultura tairona, instalada en las faldas de la Sierra Nevada de Santa Marta. Sus miembros llegaron lejos en el progreso humano. Su habitación era estable, pétrea y de cimiento fuerte. Las poblaciones grandes, de varias centenas de casas, quedan aún desparramadas en forma de ruinas por los valles de la Sierra. Esta solidez de las construcciones traduce una organización económica y social de perfiles definidos.

    Full Text Available Los resultados de la investigación realizada en el yacimiento arqueológico de Arrancaplumas, localizado en la zona de raudales del río Magdalena, entre la cuenca alta y media (Honda - Tolima y Puerto Bogotá - Cundinamarca, indican que este lugar fue habitado por largas temporadas anuales entre los siglos V y I A.C. Los pobladores emplearon en sus actividades cotidianas a lo largo de toda la ocupación una misma clase de cerámica y elaboraron una industria lítica que no presenta cambios significativos a través del tiempo.  El predominio de líticos lascados probablemente están relacionados con actividades derivadas de la pesca y la caza. La producción de alimentos vegetales se redujo principalmente al cultivo esporádico de maíz y papaya, y la recolección de frutos de palma. Durante toda la secuencia de ocupación la pesca constituyó la principal actividad de la cual derivaron su subsistencia.

    Full Text Available Se analizaron muestras de zooplancton de 16 campañas oceanógraficas, efectuadas en Bahía Magdalena, Baja California Sur, México, entre agosto de 1997 y marzo de 2001. Se identificó un total de 26 grupos taxonómicos, de los cuales los más abundantes y frecuentes fueron copépodos y quetognatos; en 2000-2001 se observó una tendencia a disminuir entre 10 y 20 el número de grupos de zooplancton. La biomasa zooplanctónica y abundancia de copépodos disminuyeron en el periodo de estudio, en contraste con los quetognatos que tuvieron un ligero aumento. Las fluctuaciones de abundancia de zooplancton no estuvieron relacionadas con la concentración de clorofila-α, a diferencia de los máximos de abundancia de zooplancton, que estuvieron asociados a los cambios de la temperatura superficial del mar. El ciclo estacional de la abundancia del zooplancton en Bahía Magdalena, indicó que en invierno el promedió fue mayor de 65.000 ind 100 m-3 , valor que aumentó en primavera a más de 99.000 ind 100 m-3 , se mantuvo en verano alrededor de 100.000 ind 100 m-3 y en otoño descendió rápidamente a casi 40.000 ind 100 m-3.Zooplankton were studied from 16 oceanographic surveys carried out in Magdalena Bay, Baja California Sur, Mexico, between August 1997 and March 2001. Twenty-six taxonomic groups were identified, the most abundant and frequent of which were copepods and chaetognaths. In 2000-2001, the number of zooplankton groups tended to decrease by 10 to 20. Both zooplankton biomass and copepod abundance declined, unlike chaetognaths, which increased slightly. Fluctuations in zooplankton abundance were independent of the chlorophyll-a concentration, whereas the maximum zooplankton abundances were associated with changes in the sea surface temperature. The seasonal zooplankton abundance cycle in Magdalena Bay indicated that, in winter, the averaged was than 65,000 ind 100 m-3 , a value that increased to more than 99,000 ind 100 m-3 in spring

    Mangrove forests which thrive along the tropical and subtropical regions are the most productive ecosystems in the world with a wide range of ecological and economical services to mankind. With the rapid urbanization across the globe, these forests tend to be destroying at an alarming rate. The area of concern for this study, Bahia Magdalena is very important for the economy of the state as nearly 50% of the artisan fisheries are established in the mangrove zone. Henceforth this study is an attempt for a regional assessment and to accurately quantify the mangroves using LANDSAT imageries for over two decades in Bahia Magdalena, Baja California. Satellite imageries from the year 1986 through 2014 were analysed to assess the prolonged changes taking place in and around the mangrove reserve. Using the estimates of land use/cover for all the years, the spatio - temporal data was validated using ArcGIS software. The results revealed that the spatial extent of mangroves are decreasing until 2005 due to the developmental plans such as tourism, shrimp farming and establishment of industries in this part of the country. During the past 10 years (~ after 2005) there is no much change in the area extent of mangrove reserves due to afforestation and conservation efforts. Thus the unbiased dataset generated may be widely used for an improved understanding of the role of mangrove forests in the socio economic aspects, protection from natural disasters, identify possible areas for conservation, restoration and rehabilitation; and improve estimates of the amount of carbon stored in mangrove vegetation and the associated marine environment. Keywords: Mangroves, LANDSAT, Bahia Magdalena, México.

    2005-01-01

    New branches of scientific disciplines often have a few paradigmatic models that serve as a testing ground for theories and a starting point for new inquiries. In the late 1990s, one of these models found fertile ground in the growing field of econophysics: the Minority Game (MG), a model for speculative markets that combined conceptual simplicity with interesting emergent behaviour and challenging mathematics. The two basic ingredients were the minority mechanism (a large number of players have to choose one of two alternatives in each round, and the minority wins) and limited rationality (each player has a small set of decision rules, and chooses the more successful ones). Combining these, one observes a phase transition between a crowded and an inefficient market phase, fat-tailed price distributions at the transition, and many other nontrivial effects. Now, seven years after the first paper, three of the key players-Damien Challet, Matteo Marsili and Yi-Cheng Zhang-have published a monograph that summarizes the current state of the science. The book consists of two parts: a 100-page overview of the various aspects of the MG, and reprints of many essential papers. The first chapters of Part I give a well-written description of the motivation and the history behind the MG, and then go into the phenomenology and the mathematical treatment of the model. The authors emphasize the 'physics' underlying the behaviour and give coherent, intuitive explanations that are difficult to extract from the original papers. The mathematics is outlined, but calculations are not carried out in great detail (maybe they could have been included in an appendix). Chapter 4 then discusses how and why the MG is a model for speculative markets, how it can be modified to give a closer fit to observed market statistics (in particular, reproducing the 'stylized facts' of fat-tailed distributions and volatility clustering), and what conclusions one can draw from the behaviour of the MG when

    The Magdalena Ridge Observatory Interferometer (MROI), a 10-telescope optical/near-IR interferometer in central NM has been conceived to be the most ambitious optical interferometric array under construction to date. With baselines ranging from 7.8 to 343 meters, and limiting magnitudes of 14 at K band, it will be able to assess many thousands of astronomical targets on spatial scales of 10's to 0.1's of milliarcseconds. After over a decade of funding from NRL and the major partner institutions (NM Tech and Cambridge University), new funding was obtained in late 2015 via a Cooperative Agreement between NM Tech and the Air Force Research Lab (AFRL) to bring the facility to a three-interferometer system capable of observing geosynchronous satellites. However, we still maintain an exciting and compelling astronomical portfolio which will produce statistical samples of: YSOs and their surrounding disks, systems dominated by mass-loss and mass-transfer, pulsational stars and binary systems, and image the environs of AGN in nearby galaxies. An update on the status and plans for MROI for the next 3 years under the current Cooperative Agreement will be presented. In addition, we will present some examples of observational applications feasible with MROI both in the near-term and as we approach the full 10-telescope facility and describe how the astronomical community can become involved in this exciting project.We wish to acknowledge our sponsors in the NM Congressional Delegation and AFRL FA #9453-15-2-0086 for our recent support.

    Full Text Available The zooplankton community structure, including copepods, euphausiids, chaetognaths, and decapod larvae, was monitored during six circadian cycles using Bongo net (500 *m mesh net samples from Bahía Magdalena, on the southwest coast of Baja California, México. Samples were obtained during three oceanographic surveys (March, July, and December 1996 to describe the changes in the zooplankton community structure throughout the main mouth of Bahía Magdalena. The zooplankton community structure showed strong changes with a close relation to environmental conditions. During March, a well-mixed water column with low temperature and salinity indicated an influence of the California Current water and local upwelling processes. During July, temperature increased a nd a wide salinity range was recorded. The stratification of the water column was intense during summer, enhancing the thermocline. The highest temperatures and salinity were recorded in December, related to the presence of the Costa Rica Coastal Current (CRCC. The thermocline deepened as water temperature increased. A typical temperate community structure with low specific richness dominated by Calanus pacificus, Nyctiphanes simplex, and Acartia clausi and high zooplankton biomass (average 9.3 and 5.5 ml 1000 m-3respectively during March and July shifted to a more complex tropical community structure with a low zooplankton biomass in December (average 0.37 ml 1000 m-3. The mouth of Bahía Magdalena has a vigorous exchange of water caused by tidal currents. The zooplankton community structure was not significantly different between the central part of Bahía Magdalena and the continental shelf outside the bay for all months. The results suggest a more dynamic inside-outside interaction of zooplankton assemblages than first thought.La estructura de la comunidad de zooplancton, incluyendo copépodos, eufáusidos, quetognatos y larvas de decápodos, fue monitoriada por seis ciclos circadianos

  11. DESIGN AND TEST OF AN INSTRUMENT FOR MEASURING MICROTHERMAL SEEING ON THE MAGDALENA RIDGE

    We have constructed and operated an automated instrument for measuring ground-level microthermal seeing at the Magdalena Ridge Observatory (MRO). The MRO is located at an altitude of 10500' in the Cibola National Forest in New Mexico, USA. It is the planned site for the MRO Optical Interferometer (MROI) planned for up to 10 collecting elements, each with a diameter of 1.4 m, and baselines eventually up to approximately 400 m. As part of the preparation for construction we deployed a system to characterize the ground-level seeing across the observatory site. The instrument is built largely of off-the-shelf components, with only the sensor head and power supply requiring electronic board assembly. Even in those cases the board architecture is very simple. The first proof-of-concept system was deployed for several weeks in the autumn of 2004, and has since undergone several iterations. The latest configuration operates entirely off batteries, incorporates wireless data acquisition, and is thus able to operate in an area with no shelter, power, or communications. In this paper we present the design of the instrument, and show initial data. The microthermal tower has four sensor pairs at heights from 0.8 to 4.41 m, significantly lower than other microthermal experiments, because of the need to characterize the seeing near the ground. We find significant variation in the contribution of this range of heights to the seeing, contributing up to 0.''3 of the seeing at some times and only 0.''02 at other times. The individual sensor power spectra have a slope in the range of 1.4--1.5, which is lower than the 1.67 slope predicted by Kolmogorov turbulence theory. We measure the well known effect of improved seeing immediately around sunset. While we find significant variation in the microthermal seeing, we did not find a pattern of corresponding variations in weather conditions, suggesting that a complicated set of factors control microthermal turbulence.

A longitudinal design with practice-level measures of access and continuity of care, patient population demographics and use of emergency care for the financial years 2009/10 to 2012/13. The main outcome measures were self-referred discharged ED attendance rate, and combined self-referred discharged ED, self-referred Walk-in Centre (WiC) and self-referred Minor Injuries Unit (MIU) attendance rate per 1000 patients. Multilevel models estimated adjusted regression coefficients for relationships between patients' emergency attendance rates and patients' reported satisfaction with opening hours and waiting time at the practice, proportion of patients having a preferred GP, and use of WiC and MIU, both between practices, and within practices over time. Practice characteristics associated with higher ED attendance rates included lower percentage of patients satisfied with waiting time (0.22 per 1% decrease, 95%CI 0.02 to 0.43) and lower percentage having a preferred GP (0.12 per 1% decrease, 95%CI 0.02 to 0.21). Population influences on higher attendance included more elderly, more female and more unemployed patients, and lower male life-expectancy and urban conurbation location. Net reductions in ED attendance were only seen for practices whose WiC or MIU attendance was high, above the 60th centile for MIU and above the 75th centile for WiC. Combined emergency care attendance fell over time if more patients within a practice were satisfied with opening hours (-0.26 per 1% increase, 95%CI -0.45 to -0.08). Practices with more patients satisfied with waiting time, having a preferred GP, and using MIU and WIC services, had lower ED attendance. Increases over time in attendance at MIUs, and patient satisfaction with opening hours

    The Magdalena river turtle, Podocnemis lewyana, is an endangered and endemic turtle from Colombia. Among the most important information needed to conserve endangered species is to identify, monitor, and protect the sites used by the species to reproduce and grow. In this study we report, for the first time, the reproductive output and the nesting beaches of P. lewyana in the Claro Cocorna Sur River, a tributary of the Magdalena river drainage. We systematically examined a river transect of 8 km with 14 sandy beaches during two nesting seasons in one year. We recorded a yearly production of 47 clutches, 957 eggs, and two preferred nesting beaches: Alto Bonito with 51 %, and Belgica with 28.3 % of this reproductive output. Aafuver, a community-based organization, has led a headstarting program since 2010 to decrease in-situ egg mortality due to predation on nesting beaches. Aafuver collects and incubates the eggs ex-situ, raises the hatchlings for one to five months and then releases them into the same river. To understand potential effects of such egg manipulation, we monitored and compared in-situ and ex-situ incubation temperatures. We found ex-situ temperatures below the pivotal temperature known for P. lewyana and below the temperatures in nesting beaches. Finally, we monitored hatchlings growth under aafuver captive conditions, and found that hatchlings duplicated their body mass during the first three months of age. Egg weight was strongly associated to body weight at hatching; however this association is lost by the third month of age. We strongly encourage supporting this community-based conservation program, and the protection of the Claro Cocorna Sur River as an important nesting and growth habitat for the conservation of P. lewyana.

De 112 taxa identificados, los nauplios de balanos y los cladóceros Penilia avirostris y Pseudevadne tergestina fueron los más comunes y abundantes y con niveles de variación diaria de más del 100%. Los copépodos constituyeron una quinta parte de la abundancia del zooplancton y 7 de las 80 especies encontradas se registran por vez primera en la zona de estudio. La abundancia del zooplancton fue parcialmente coherente con la hidrografía de la bahía, así como con un modelo de retención de partículas. Las 3 especies de copépodos más abundantes fueron más numerosas a inicio de la serie pero tendieron a reducir su densidad hacia el fin del lapso de estudio.

  14. Relationship between petrographic pore types and core measurements in sandstones of the Monserrate Formation, upper Magdalena Valley, Colombia

    Ehrlich, R; Cobaleda, G; Barclay, Ferm

    1997-01-01

    Patterns of porosity in sandstones of the Monserrate Formation (Upper Magdalena Valley) exposed in polished blocks have been digitally recorded using an image processor coupled to a scanning electron microscope operated in back scatter electron mode. Additionally, porosity, permeability and response to mercury injection-capillary pressure tests were measured on some of the imaged samples. Porosity pattern were evaluated via an erosion/dilation-differencing image-processing algorithm and then classified by the self-training classifier, SAWVEC. Changes in the resulting pore type proportions were strongly associated with changes in the mercury porosimetry curves. From the image processing data, five pore types, sufficient to include all of the variability in size and shape of the patterns of porosity, were identified. Variations in the number of pares of each type per unit cross sectional area were related to variations in permeability. The resultant relationships with mercury porosimetry demonstrated that pares of the same type tends to form microcircuits characterized by a limited throat size range. Permeability modeling showed that intergranular Pare Types 2 and 4 (secondary porosity resulting from carbonate dissolution) are responsible for permeability in the 0,01 - 0,1 0 Darcy range. Type 5 pares (large molds) slightly contribute to permeability, except in coarse grained rocks where they are efficiently connected by micro fractures

Firstly I show how, in the late 1850s, the emerging Colombian body of medical doctors elaborated peculiar notions on fevers by articulating the European medical theories (i.e. the miasmatic theory and the climatic determination of diseases with the negative valuation of the hot climate. Secondly, I explain how free trade policies in the mid-1800s, and the economic and ideological impacts of the agricultural export of tobacco and indigo determined doctors' interest in the epidemics occurring in the production centers and also, therefore, the emergence of the notion of 'Magdalena fevers'. I also show how doctors established a causal association between the productive process of those goods and the fevers.

Evaluar la biodiversidad faunística asociada a ganadería vacuna de doble propósito en dos potreros estructurados con Botriochloa pertusa (colosoana como herbácea dominante, uno de ellos plantado con Crescentia cujete (Bignoniaceae como fuente de alimento adicional y otro con escaso y disperso arbolado. Materiales y métodos. El área de estudio está ubicada en el municipio de Pinto, Magdalena. Cada potrero evaluado fue de 10 ha, se mantuvo en cada uno un lote de quince vacas (½ Cebú, ¼ Pardo y ¼ Costeño con Cuernos, la separación entre las áreas muestreadas fue de 500m. Los registros de fauna se condujeron mediante punto fijo de conteo, en diez sitios de avistamiento, durante 20 días continuos, con cubrimiento visual amplio. Al ganado vacuno adulto presente en las dos áreas de trabajo se le realizó un pesaje individual al inicio del trabajo y al final del mismo, con el fin de determinar posibles diferencias entre ellos. Resultados. Estadísticamente el número de individuos y el número de especies presentaron diferencias significativas, siendo mayor la diversidad biológica para el potrero que poseía la plantación de C. cujete, mientras que el peso corporal de las vacas sometidas a pastoreo en las dos áreas no presentó diferencias significativas. Conclusiones. Se demuestra la importancia de este modelo pecuario como promotor de la conservación faunística local al convertirse enrefugio de variadas especies silvestres, al tiempo que mantiene la productividad existente sin alterar el ambiente sustancialmente.

  8. The Trojan minor planets

    Spratt, Christopher E.

    1988-08-01

    There are (March, 1988) 3774 minor planets which have received a permanent number. Of these, there are some whose mean distance to the sun is very nearly equal to that of Jupiter, and whose heliocentric longitudes from that planet are about 60°, so that the three bodies concerned (sun, Jupiter, minor planet) make an approximate equilateral triangle. These minor planets, which occur in two distinct groups, one preceding Jupiter and one following, have received the names of the heroes of the Trojan war. This paper concerns the 49 numbered minor planets of this group.

    Full Text Available Black Sigatoka (Mycosphaerella fijiensis Morelet disease is the greatest limiting factor affecting banana crop production across the world. The pathogen´s severity has reached epidemic levels and is exacerbated by the cultivation of monocultures and genetically uniform clones. In Colombia, losses occur in the exporting regions of Uraba and Magdalena, where its management depends on the use of agrochemicals, without achieving eradication. In the search for methods to reduce the pathogen’s effect within the banana zone of the departamento del Magdalena, Colombia, the relationship between climate, soil properties, and the presence of the disease was determined. Were utilized data from geographic informational systems, digitalized the data from the soil variables reported in the soil study conducted by IGAC (2009, records from weather stations in the region, and data showing the incidence rate of the pathogen. As a result of the study were established three areas (high, medium and low incidence rate and discovered a positive correlation between the incidence rate of the disease with precipitation (r = 0.56, interchangeable magnesium, Mg+2 (r = 0.45, microporosity (r = 0.40, clay content (r = 0.54, and evaporation (r = 0.51. Were observed that there are soil conditions that influence the presence of the disease, variables that should be kept in mind in the management of banana cultivation.

  7. Defining minors' abortion rights.

    Science.gov (United States)

    Rhodes, A M

    1988-01-01

    The right to abortion is confirmed in the Roe versus Wade case, by the US Supreme Court. It is a fundamental right of privacy but not an absolute right, and must consider state interests. During the first trimester of pregnancy abortion is a decision of the woman and her doctor. During the second trimester of pregnancy the state may control the abortion practice to protect the mothers health, and in the last trimester, it may prohibit abortion, except in cases where the mother's life or health are in danger. The states enacted laws, including one that required parents to give written consent for a unmarried minor's abortion. This law was struck down by the US Court, but laws on notification were upheld as long as there was alternative procedures where the minor's interests are upheld. Many of these law have been challenged successfully, where the minor was judged mature and where it served her best interests. The state must enact laws on parental notification that take into consideration basic rights of the minor woman. Health professionals and workers should be aware of these laws and should encourage the minor to let parents in on the decision making process where possible.

For which a random sample of 100 students was taken, who are part of various academic semesters, answered a questionnaire that asked for their views on the process. The main results support the view that students have a huge sense of belonging to the program and believe that it deserves accreditation by the Ministry and, further, this certificate becomes something positive for their careers. We conclude that, despite the apparent acceptance of the conditions of program quality, it is necessary that efforts be brought forward to create a culture of quality throughout the student population and a and a nationwide study is proposed to investigate these perceptions in various universities in Colombia, having as reference the implications of the context to which they belong.

  15. Application of MODIS Products to Infer Possible Relationships Between Basin Land Cover and Coastal Waters Turbidity Using the Magdalena River, Colombia, as a Case Study

    2012-01-01

    Basin development and consequent change in basin land cover have been often associated with an increased turbidity in coastal waters because of sediment yield and nutrients loading. The later leads to phytoplankton abundance further exacerbating water turbidity. This subsequently affects biological and physical processes in coastal estuaries by interfering with sun light penetration to coral reefs and sea grass, and even affecting public health. Therefore, consistent estimation of land cover changes and turbidity trend lines is crucial to design environmental and restoration management plans, to predict fate of possible pollutants, and to estimate sedimentary fluxes into the ocean. Ground solely methods to estimate land cover change would be unpractical and traditional methods of monitoring in situ water turbidity can be very expensive and time consuming. Accurate monitoring on the status and trends of basin land cover as well as the water quality of the receiving water bodies are required for analysis of relationships between the two variables. Use of remote sensing (RS) technology provides a great benefit for both fields of study, facilitating monitoring of changes in a timely and cost effective manner and covering wide areas with long term measurements. In this study, the Magdalena River basin and fixed geographical locations in the estuarine waters of its delta are used as a case to study the temporal trend lines of both, land cover change and the reflectance of the water turbidity using satellite technology. Land cover data from a combined product between sensors Terra and Aqua (MCD12Q1) from MODIS will be adapted to the conditions in the Magdalena basin to estimate changes in land cover since year 2000 to 2009. Surface reflectance data from a MODIS, Terra (MOD09GQ), band 1, will be used in lieu of in situ water turbidity for the time period between 2000 and present. Results will be compared with available existing data.

Somethings that need to be considered in the preparation of the surgery is minor tools, operating rooms and operating tables, lighting, maintenance of tools and equipment, sterilization and desinfection equipment, preparation of patients and anesthesia. In general cysts is walled chamber that consist of fluid, cells and the remaining cells. Cysts are formed not due to inflammation although then be inflamed. Lining of the cysts wall is composed of fibrous tissue and usually coated epithelial cells or endothelial. Cysts formed by dilated glands and closed channels, glands, blood vessels, lymph channels or layers of the epidermis. Contents of the cysts wall consists of the results is serum, lymph, sweat sebum, epithelial cells, the stratum corneum, and hair. /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;}

  17. Quelques aspects de l'évolution géomorphologique quaternaire du haut bassin du Magdalena (Colombie

    Directory of Open Access Journals (Sweden)

    1974-01-01

    Full Text Available Le bassin supérieur du Rio Magdalena présente les caractéristiques suivantes: 1 L'allure générale du bassin montre une influence très nette de la tectonique. Il s'est développé grâce à la présence d'un ensemble de blocs affaissés relativement les uns par rapport aux autres et entourés de blocs soulevés qui forment les limites du bassin. Dans certains cas des édifices volcaniques se superposent à ces blocs (Nevado del Huila, parâmes de Las Papas, par exemple. 2 Dans certaines parties du bassin (Nevado del Huila, environs du rio Mazamoras, et de Pitalito, le volcanisme s'est développé durant tout le Quaternaire. De la sorte, en général on observe un paroxysme volcanique durant la période d'accumulation de QIII dont la position géomorphologique est très semblable à celle du Mindel européen (Nebraska d'Amérique du Nord. Les matériaux volcaniques ont ainsi contribué à la mise en place de l'accumulation QIII mais cette accumulation n'est pas un produit du volcanisme car on l'observe bien développée dans des vallées ou il n'y eut aucune activité volcanique à cette époque. Ainsi, la mise en place du remplissage QIII provient d'une oscillation climatique. La granulométrie très grossière du matériel QIII provient de la combinaison du volcanisme et de cette oscillation climatique. 3 Dans le bassin, les événements morphogénétiques les plus saillants sont les suivants: - une incision extrêmement profonde des talwegs des avant l'accumulation de QIII cette incision a atteint au moins le niveau des rivières actuelles - la fossilisation des cañons incisés durant cette phase par l'accumulation très épaisse du matériel QIII. - postérieurement, a fonctionné une tendance très générale à l'incision uniquement interrompue par les phases d'accumulation QI et QII. Actuellement, cette incision n'est toujours pas arrivée au niveau atteint avant l'accumulation de QIII. Durant cette période d'incision des rivi

    1991-01-01

    The concept of minor actinide burner reactor is proposed as an efficient way to transmute long-lived minor actinides in order to ease the burden of high-level radioactive waste disposal problem. Conceptual design study of minor actinide burner reactors was performed to obtain a reactor model with very hard neutron spectrum and very high neutron flux in which minor actinides can be fissioned efficiently. Two models of burner reactors were obtained, one with metal fuel core and the other with particle fuel core. Minor actinide transmutation by the actinide burner reactors is compared with that by power reactors from both the reactor physics and fuel cycle facilities view point. (author)

    Full Text Available Con miras a evaluar posibles efectos de la recomunicación del río Magdalena con su antiguo delta, se determinó la abundancia y composición de la rotiferofauna del Complejo de Pajarales (CP, durante el período de mayor abundancia anual de zooplancton. El phylum Rotifera fue seleccionado por sus altas tasas reproductivas y eficiencia en procesos de transformación energética. Las muestras se colectaron con botella van Dorn durante la segunda temporada lluviosa de 2006. En cada una de las cuatro estaciones analizadas se registraron la salinidad, temperatura, pH y oxígeno disuelto. La diversidad se calculó empleando el índice de Shannon-Wiener H’ (log10 comparando estaciones y fechas de muestreo para establecer variaciones en el período de estudio. Gráficamente se relacionaron variables fisicoquímicas con valores de diversidad que emplearon un α de 0.05 y 95% de intervalo de confianza. En total, fueron encontrados 20 morfotipos pertenecientes a las familias Brachionidae, Lecanidae, Filiniidae, Synchaetidae, Hexarthriidae y Testudinellidae, siendo Brachionidae y Lecanidae las más abundantes. La relación entre diversidad y variables fisicoquímicas, indica que la salinidad es la principal responsable de la diversidad de rotíferos. En conclusión, la rotiferofauna actual en el CP es más abundante y diversa que hace 16 años, antes de la recomunicación con el río Magdalena. Así mismo, la concentración de oxigeno disuelto, pH y salinidad son diferentes. Teniendo en cuenta que la salinidad es el factor que más influyó en la diversidad de rotíferos, la reapertura de canales probablemente favoreció el incremento en la diversidad de rotíferos en el CP.

  1. BOOK REVIEW: Minority Games

    Science.gov (United States)

    Metzler, R.

    2005-02-01

    New branches of scientific disciplines often have a few paradigmatic models that serve as a testing ground for theories and a starting point for new inquiries. In the late 1990s, one of these models found fertile ground in the growing field of econophysics: the Minority Game (MG), a model for speculative markets that combined conceptual simplicity with interesting emergent behaviour and challenging mathematics. The two basic ingredients were the minority mechanism (a large number of players have to choose one of two alternatives in each round, and the minority wins) and limited rationality (each player has a small set of decision rules, and chooses the more successful ones). Combining these, one observes a phase transition between a crowded and an inefficient market phase, fat-tailed price distributions at the transition, and many other nontrivial effects. Now, seven years after the first paper, three of the key players—Damien Challet, Matteo Marsili and Yi-Cheng Zhang—have published a monograph that summarizes the current state of the science. The book consists of two parts: a 100-page overview of the various aspects of the MG, and reprints of many essential papers. The first chapters of Part I give a well-written description of the motivation and the history behind the MG, and then go into the phenomenology and the mathematical treatment of the model. The authors emphasize the `physics' underlying the behaviour and give coherent, intuitive explanations that are difficult to extract from the original papers. The mathematics is outlined, but calculations are not carried out in great detail (maybe they could have been included in an appendix). Chapter 4 then discusses how and why the MG is a model for speculative markets, how it can be modified to give a closer fit to observed market statistics (in particular, reproducing the `stylized facts' of fat-tailed distributions and volatility clustering), and what conclusions one can draw from the behaviour of the MG

    Lack of adequate information about the taxonomic and evolutionary relationships, ecology, biology, and distribution of several species belonging to the family Potamotrygonidae makes these species vulnerable to anthropic activities, including commercial overexploitation for the ornamental fish market. The aim of this study was to investigate the systematic relationships among genera and species belonging to this family by analyses of three mitochondrial gene regions. Samples were collected from the main river basins in Colombia and Venezuela for four genera and seven species of the family, as well as for what appear to be unidentified species. Three mitochondrial molecular markers COI, Cytb, and ATP6 were amplified and sequenced. Maximum likelihood and Bayesian inference analysis were performed to obtain topologies for each marker and for a concatenated dataset including the three genes. Small dataset may compromise some methods estimations of sequence divergence in the ATP6 marker. Monophyly of the four genera in Potamotrygonidae was confirmed and phylogenetic relationships among members of the Potamotrygon genus were not clearly resolved. However, results obtained with the molecular marker Cytb appear to offer a good starting point to differentiate among genera and species as a tool that could be used for barcoding. The application of this gene as a barcode could be applied for management and regulation of extraction practices for these genera. Sequencing complete mitochondrial genomes would be the next step for testing evolutionary hypothesis among these genera. Population structure analyses should be undertaken for Paratrygon, Potamotrygon magdalenae and motoro.

    Full Text Available Moniliophthora roreri is the fungal pathogen that causes frosty pod rot (FPR disease of Theobroma cacao L., the source of chocolate. FPR occurs in most of the cacao producing countries in the Western Hemisphere, causing yield losses up to 80%. Genetic diversity within the FPR pathogen population may allow the population to adapt to changing environmental conditions and adapt to enhanced resistance in the host plant. The present study developed SNP markers from RNASeq results for 13 M. roreri isolates and validated the markers for their ability to reveal genetic diversity in an international M. roreri collection. The SNP resources reported herein represent the first study of RNASeq-derived SNP validation in M. roreri and demonstrates the utility of RNASeq as an approach for de novo SNP identification in M. roreri. A total of 88 polymorphic SNPs were used to evaluate the genetic diversity of 172 M. roreri cacao isolates resulting in 37 distinct genotypes (including 14 synonymous groups. Absence of heterozygosity for the 88 SNP markers indicates reproduction in M. roreri is clonal and likely due to a homothallic life style. The upper Magdalena Valley of Colombia showed the highest levels of genetic diversity with 20 distinct genotypes of which 13 were limited to this region, and indicates this region as the possible center of origin for M. roreri.

  6. Assessing bovine babesiosis in Rhipicephalus (Boophilus microplus ticks and 3 to 9-month-old cattle in the middle Magdalena region, Colombia

    Directory of Open Access Journals (Sweden)

    Sandra Ríos-Tobón

    Full Text Available Babesia sp. is a protozoan hemoparasite that affects livestock worldwide. The Colombian Middle Magdalena is an enzootic region for babesiosis, but there is no previous research providing detail on its transmission cycle. This study aims to assess some Babesia sp. infection indicators in cattle and ticks from the area, by using direct microscopic and molecular techniques to detect the infection. In the cattle, 59.9% and 3.4 % positivity values for B. bigemina and mixed infection (B. bovis + B. bigemina were found respectively. In ticks, the positivity of B. bigemina reached 79.2% and 9.4% for the mixed infection. The degree of infestation in the region was 3.2 ticks per bovine. There was positive correlation between tick control acaricide frequencies and infestation in bovines. This leads us to infer that control periodicity greater than 90 days, in stable zones, is an abiotic factor that benefits the acquisition of protective immunity in calves, the natural control of the infection and eventual disease absence. It is necessary to monitor the disease by applying new entomological and parasitological indicators showing the complexity of this phenomenon.

  8. Recruitment of minority physicians into careers in internal medicine.

    Potts, J T

    1992-06-15

    Despite some initial success in the early 1970s, the important goal of increasing the numbers of underrepresented minorities in medical school and on medical faculties has stalled short of proportionate representation. To further the current efforts of the Association of Professors in Medicine (APM) and other national medical groups that are devoted to improving the numbers of minorities in medicine, ideas and program information must be shared among institutions. In this spirit, we review our experience at Massachusetts General Hospital. We found that the first step toward this goal must be an institutional commitment based on increased awareness and on special effort focused on housestaff recruitment. Once the numbers of minorities increase, the department chairperson, training program directors, and other involved faculty can work with younger minority physicians; the cooperative relationship thus created can guide the development of a strong minority recruitment program without requiring an undue time commitment from minority trainees and faculty. The APM has a combined goal: to achieve early practical results in individual departments, to play a catalytic role with the community and other national medical organizations, and to increase the number of minorities entering medical school and careers in medicine generally.

  9. Issues in contracting with small minority businesses

    Wood, M.T.; Radford, M.L.; Saari, L.M.; Wright, J.

    1986-04-01

    The focus of this investigation was to identify issues central to increasing the involvement of small minority businesses (MBs) in federal or prime contracts with the Department of Energy (DOE), as a foundation for designing a program to assist buyers of contracted goods and services. The approach to determining issues involved interviewing the owners of 15 MBs, representing a range of businesses, and buyers and purchasing officers from three large DOE prime contractors. The interviewees identified issues related to positive working relationships and rated a predetermined set of 27 potential MB-DOE problems regarding their existence and criticalness. The issues identified by MBs were of two broad types. The predominant issues and barriers were associated with their being small businesses. Secondary issues reflected the disadvantaged status of the business (woman and/or minority-owned).

    Full Text Available The barnacle, Chelonibia testudinaria, is an obligate commensal of sea turtles that may show population variability according to the physical characteristics of the environment and properties of turtle hosts; therefore, we characterized the distributional patterns and the potential effects on health of C. testudinaria on juvenile green turtles in Bahia Magdalena, Mexico. Barnacle attachment position, abundance, and size-class structure were described, while the relationship between barnacle abundance and turtle health condition and size was explored through generalized linear models. Juvenile green turtles of Bahía Magdalena offered an appropriate habitat for C. testudinaria as their frequency of occurrence was high and their abundance was similar to that found in other green turtle populations. Barnacles showed an aggregated distribution that may be facilitating their reproduction during the warm summer months. Barnacle abundance is unaffected by turtle size or seasonality, while their attachment position appears to be influenced by water flow over the turtle carapace and by plastron abrasion by the turtle against the sea floor. Healthier turtles exhibited a decreased barnacle load; therefore we suggest that C. testudinaria abundance may be a useful indicator of health for juvenile green turtles.El balano Chelonibia testudinaria es un comensal obligado de tortugas marinas que puede presentar variaciones poblacionales de acuerdo a características ambientales y de las tortugas que coloniza; por lo tanto, caracterizamos su distribución y el efecto sobre la salud de tortugas verdes (Chelonia mydas juveniles en bahía Magdalena, México. Se describieron la posición de adherencia, la abundancia y la estructura de tallas de C. testudinaria, mientras que la relación entre su abundancia y la salud y el tamaño de las tortugas se exploró a través de modelos lineales generalizados.

  16. Impact of minor actinide recycling on sustainable fuel cycle options

    Energy Technology Data Exchange (ETDEWEB)

    2017-11-01

    The recent Evaluation and Screening study chartered by the U.S. Department of Energy, Office of Nuclear Energy, has identified four fuel cycle options as being the most promising. Among these four options, the two single-stage fuel cycles rely on a fast reactor and are differing in the fact that in one case only uranium and plutonium are recycled while in the other case minor actinides are also recycled. The two other fuel cycles are two-stage and rely on both fast and thermal reactors. They also differ in the fact that in one case only uranium and plutonium are recycled while in the other case minor actinides are also recycled. The current study assesses the impact of recycling minor actinides on the reactor core design, its performance characteristics, and the characteristics of the recycled material and waste material. The recycling of minor actinides is found not to affect the reactor core performance, as long as the same cycle length, core layout and specific power are being used. One notable difference is that the required transuranics (TRU) content is slightly increased when minor actinides are recycled. The mass flows are mostly unchanged given a same specific power and cycle length. Although the material mass flows and reactor performance characteristics are hardly affected by recycling minor actinides, some differences are observed in the waste characteristics between the two fuel cycles considered. The absence of minor actinides in the waste results in a different buildup of decay products, and in somewhat different behaviors depending on the characteristic and time frame considered. Recycling of minor actinides is found to result in a reduction of the waste characteristics ranging from 10% to 90%. These results are consistent with previous studies in this domain and depending on the time frame considered, packaging conditions, repository site, repository strategy, the differences observed in the waste characteristics could be beneficial and help improve

    Dictionary of Minor Planet Names, Fifth Edition, is the official reference for the field of the IAU, which serves as the internationally recognised authority for assigning designations to celestial bodies and any surface features on them. The accelerating rate of the discovery of minor planets has not only made a new edition of this established compendium necessary but has also significantly altered its scope: this thoroughly revised edition concentrates on the approximately 10,000 minor planets that carry a name. It provides authoritative information about the basis for all names of minor planets. In addition to being of practical value for identification purposes, this collection provides a most interesting historical insight into the work of those astronomers who over two centuries vested their affinities in a rich and colorful variety of ingenious names, from heavenly goddesses to more prosaic constructions. The fifth edition serves as the primary reference, with plans for complementary booklets with newl...

    The Magdalena Cauca Macrobasin (MCMB) in Colombia, with an area of about 257,000 km2, is the largest and most important water resources system in the country. With almost 80% of the Colombian population (46 million people) settled in the basin, it is the main source of water for demands including human consumption, agriculture, hydropower generation, industrial activities and ecosystems. Despite its importance, the basin has witnessed enormous changes in land-cover and extensive deforestation during the last three decades. To make things more complicated, the MCMB currently lacks a set of tools to support planning and decision making processes at scale of the whole watershed. Considering this, the MCMB has been selected as one of the six different regional case studies in the eartH2Observe research project, in which hydrological and meteorological reanalysis products are being validated for the period 1980-2012. The combined use of the hydrological and meteorological reanalysis data, with local hydrometeorological data (precipitation, temperature and streamflow) provided by the National Hydrometeorological Agency (IDEAM), has given us the opportunity to implement and test three hydrological models (VIC, WFLOW and a Water Balance Model based on the Budyko framework) at the basin scale. Additionally, results from the global models in the eartH2Observe hydrological reanalysis have been used to evaluate their performance against the observed streamflow data. This paper discusses the comparison between streamflow observations and simulations from the global hydrological models forced with the WFDEI data, and regional models forced with a combination of observed and meteorological reanalysis data, in the whole domain of the MCMB. For the three regional models analysed results show good performances for some sub-basins and poor performances for others. This can be due to the smoothing of the precipitation fields, interpolated from point daily rainfall data, the effect of

Una de las explicaciones a este fenómeno es el aumento de actitudes que promueven los llamados factores de riesgo modificables como el sedentarismo, los malos hábitos alimenticios, el tabaquismo y el alcoholismo; lo anterior sumado a factores no modificables como la herencia y el género, contribuyen al desencadenamiento de las enfermedades cardiovasculares. Adicionalmente estas patologías fueron consideradas casi exclusivas de los países industrializados, sin embargo el problema se está expandiendo a los países en vía de desarrollo como Colombia, esto quizá producto del aumento en el ritmo de vida y a la adquisición de estilos de vida poco saludables El objetivo de este estudio fue investigar la presencia de factores de riesgo asociados con las enfermedades cardiovasculares en un grupo de estudiantes del programa de medicina de la Universidad del Magdalena, como parte de un trabajo de investigación formativa correspondiente a la cátedra de Bioquímica.

The EAA continued this effort by recruiting and providing fellowships to students who aspired to continue their education at the graduate level. The fellowships provided funding for tuition, fees, books, technology, and stipends to assist with room, board, and living expenses during the academic year and salary, transportation, and living expenses to those students who secured internships with the Department of Energy. Additionally the EAA designed and implemented needed support systems to ensure successful completion of the Masters degree programs, including but not limited to membership in professional associations, attendance at industry and academic conferences, and professional development workshops, and tutorial assistance if needed. This program assisted over 80 students directly and society-at-large by helping to educate and develop future physicists, engineers, biostatisticians, and researchers who will have the necessary skillsets to fill the increasing numbers of positions that require such expertise.

  12. Minority workers or minority human beings? A European dilemma

    Science.gov (United States)

    Skutnabb-Kangas, Tove; Phillipson, Robert

    1996-07-01

    "European" identities may be politonymic, toponymic, ethnomyic or linguonymic (Bromley 1984). Each dimension may affect whether migrant minorities are treated as "European", and influence their schooling, integration and rights. Treatment and terminology vary in different states and periods of migration. However, the position for immigrated minorities is that they are still largely seen as workers rather than human beings with equal rights. Lack of success in schools is blamed on the migrants themselves rather than the educational system. This construction of migrants as being deficient is parallel to educational practice which falls within a UN definition of linguistic genocide, and contributes to mis-education. If current efforts in international bodies to codify educational linguistic human rights were to lead to greater support for minorities, this could assist in a redefinition of national identities and a reduction of racism and conflict.

  13. Minors and Sexting: Legal Implications.

    Science.gov (United States)

    Lorang, Melissa R; McNiel, Dale E; Binder, Renée L

    2016-03-01

    Sexting is the sending or forwarding of sexually explicit photographs or videos of the sender or someone known to the sender via cell phone. It has become common practice among young people, as cell phones are being given to adolescents at ever younger ages. Youths often send messages without giving appropriate thought to the content of the images. In studies on the subject, rates of minors who have sent sexual images range from 4 to 25 percent, depending on the age of the youths surveyed, the content of the messages and other factors. Because transferring and viewing sexually explicit material when the subject is a minor can be considered child pornography, there can be serious legal consequences. Several states have enacted legislation to help differentiate between child pornography and sexting by minors. The trend reflected in statutes has been that minors involved in sexting without other exacerbating circumstances should be charged with a less serious offense. There is no clear national consensus on how sexting by minors is adjudicated, and therefore we compared several statutes. Case examples are used to illustrate the range of legal outcomes, from felony charges to no charges. Two sexting episodes that were followed by suicide are described. We also address the role of the forensic mental health professional. © 2016 American Academy of Psychiatry and the Law.

    2017-12-01

    Minorities are in an inferior position in society and therefore vulnerable in many aspects. This study analyzes legislative vulnerability and aims to categorize as "weak" or "strong" the protection conferred by law to the following minorities: elderly, disabled, LGBT, Indians, women, children/ adolescents and black people. In order to do so, it was developed a documental research in 30 federal laws in which legal provisions were searched to protect minorities. Next, the articles were organized in the following categories: civil, criminal, administrative, labor and procedural, to be analyzed afterwards. Legal protection was considered "strong" when there were legal provisions that observed the five categories and "weak" when it did not meet this criterion. It was noted that six groups have "strong" legislative protection, which elides the assertion that minorities are outside the law. The exception is the LGBT group, whose legislative protection is weak. In addition, consecrating rights through laws strengthens the institutional channels for minorities to demand their rights. Finally, it was observed that the legislative protection granted tominorities is not homogeneous but rather discriminatory, and there is an interference by the majority group in the rights regulation of vulnerable groups.

    Denny, W A

    2001-04-01

    Recent work on a number of different classes of anticancer agents that alkylate DNA in the minor groove is reviewed. There has been much work with nitrogen mustards, where attachment of the mustard unit to carrier molecules can change the normal patterns of both regio- and sequence-selectivity, from reaction primarily at most guanine N7 sites in the major groove to a few adenine N3 sites at the 3'-end of poly(A/T) sequences in the minor groove. Carrier molecules discussed for mustards are intercalators, polypyrroles, polyimidazoles, bis(benzimidazoles), polybenzamides and anilinoquinolinium salts. In contrast, similar targeting of pyrrolizidine alkylators by a variety of carriers has little effect of their patterns of alkylation (at the 2-amino group of guanine). Recent work on the pyrrolobenzodiazepine and cyclopropaindolone classes of natural product minor groove binders is also reviewed.

    This article concerns the rights and duties of ethnic minority children in education in Denmark. More specifically, it discusses the policy of compulsory bussing of ethnic minority children based on language screenings that was legalized by the Danish Parliament in 2005. The policy concerns...... the meeting between citizens with an ethnic minority background and the Danish state, represented by welfare institutions, in this case public elementary schools, and changes the character of this meeting for the individuals involved. In the article, I concentrate on two rights at stake in this meeting......, namely the right to free choice of school and the right – or duty? – to obtain more-equal opportunities in education. The policy creates a dilemma between these two rights and furthermore between a right and a duty to obtain better education results. The article discusses whether the bussing policy may...

  20. Happiness and Sexual Minority Status.

    Thomeer, Mieke Beth; Reczek, Corinne

    2016-10-01

    We used logistic regression on nationally representative data (General Social Survey, N = 10,668 and N = 6680) to examine how sexual minority status related to happiness. We considered two central dimensions of sexual minority status-sexual behavior and sexual identity. We distinguished between same-sex, both-sex, and different-sex-oriented participants. Because individuals transition between sexual behavior categories over the life course (e.g., from both-sex partners to only same-sex partners) and changes in sexual minority status have theoretical associations with well-being, we also tested the associations of transitions with happiness. Results showed that identifying as bisexual, gay, or lesbian, having both male and female partners since age 18, or transitioning to only different-sex partners was negatively related to happiness. Those with only same-sex partners since age 18 or in the past 5 years had similar levels of happiness as those with only different-sex partners since age 18. Additional tests showed that the majority of these happiness differences became non-significant when economic and social resources were included, indicating that the lower happiness was a product of structural and societal forces. Our findings clearly and robustly underscored the importance of taking a multi-faceted approach to understanding sexuality and well-being, demonstrating that not all sexual minority groups experience disadvantaged happiness. Our study calls for more attention to positive aspects of well-being such as happiness in examinations of sexual minorities and suggests that positive psychology and other happiness subfields should consider the role of sexual minority status in shaping happiness.

    We used logistic regression on nationally representative data (General Social Survey, N = 10,668 and N = 6,680) to examine how sexual minority status related to happiness. We considered two central dimensions of sexual minority status—sexual behavior and sexual identity. We distinguished between same-sex, both-sex, and different-sex oriented participants. Because individuals transition between sexual behavior categories over the life course (e.g., from both-sex partners to only same-sex partners) and changes in sexual minority status have theoretical associations with well-being, we also tested the effects of transitions on happiness. Results showed that identifying as bisexual, gay, or lesbian, having both male and female partners since age 18, or transitioning to only different-sex partners was negatively related to happiness. Those with only same-sex partners since age 18 or in the past five years had similar levels of happiness as those with only different-sex partners since age 18. Additional tests showed that the majority of these happiness differences became non-significant when economic and social resources were included, indicating that the lower happiness was a product of structural and societal forces. Our findings clearly and robustly underscored the importance of taking a multi-faceted approach to understanding sexuality and well-being, demonstrating that not all sexual minority groups experience disadvantaged happiness.

    Field, petrographic, and geochemical characterization along with U-Pb zircon geochronology of the Jurassic plutons exposed in the Upper Magdalena Valley (Colombia) allowed recognizing distinct western and eastern suites formed in at least three magmatic pulses. The western plutons crop out between the eastern flank of the Central Cordillera and the Las Minas range, being limited by the Avirama and the Betania-El Agrado faults. The western suite comprises a quartz monzonite - quartz monzodiorite - quartz diorite series and subordinate monzogranites. Chemically, the rocks are high-K calc-alkaline I-type granitoids (some reaching the shoshonitic series) with metaluminous of magnesium affinity. Trace-element tectonic discrimination is consistent with magmatism in a continental arc environment. Most rocks of this suite crystallized between 195 and 186 Ma (Early Jurassic, Pliensbachian), but locally some plutons yielded younger ages between 182 and 179 Ma (Early Jurassic, Toarcian). The eastern suite crops out in the eastern margin of the Upper Magdalena Valley, east of the Betania - El Agrado fault. Plutons of this unit belong to the monzogranite series with rock types ranging between syenogranites and granodiorites. They are high-K calc-alkaline continental granitoids, some metaluminous and some peraluminous, related to I-type granites generated in a volcanic arc. Crystallization of the suite was between 173 and 169 Ma (Middle Jurassic, Aalenian-Bajocian), but locally these rocks contain zircon with earlier inherited ages related to the magmatic pulse of the western suite between 182 and 179 Ma (Early Jurassic, Toarcian). The evolution of the Jurassic plutons in the Upper Magdalena Valley is best explained by onset or increase in subduction erosion of the accretionary prism. This explains the eastward migration of the arc away from the trench. Subduction of prism sediments increased the water flux from the subducting slab, decreasing solidus temperatures, therefore

  9. Minority game with SK interactions

    2013-01-01

    A batch minority game with fake random history and additional SK-like quenched interaction is introduced and analysed. A mixing parameter λ quantifies the admixture and dictates the relative dominance of the two contributions: if λ → 0, agent decisions are based on their strategies and point-scores alone, as in the pure minority game, whereas for λ > 0 the agents also communicate with each other directly and update their points accordingly. Keeping the minority game dynamics in which the agents’ points are updated in parallel at each time step, the aim is to understand what happens if instead of simply using the normal strategy-based decisions, the agents also take account of an ‘effective field’ generated by the other agents. It is shown that the SK interaction introduces a ‘noise’ term which is broader than that in the normal minority game and which furthermore kills the normal phase transition. It is also shown that the same effect would occur if, instead of an SK interaction, Gaussian-distributed quenched random fields are added. By calculating order parameters in the time-translational invariant phase we show that the system is persistent in a ergodic phase. Both simulational and analytical results are presented. (paper)

    Minor adolescent patients have a legal right to access certain medical services confidentially without parental consent or notification. We sought to assess physicians' knowledge of these laws, attitudes around the provision of confidential care to minors, and barriers to providing confidential care. An anonymous online survey was sent to physicians in the Departments of Family Medicine, Internal Medicine-Pediatrics, Obstetrics/Gynecology, and Pediatrics at the University of Michigan. Response rate was 40% (259/650). The majority of physicians felt comfortable addressing sexual health, mental health, and substance use with adolescent patients. On average, physicians answered just over half of the legal knowledge questions correctly (mean 56.6% ± 16.7%). The majority of physicians approved of laws allowing minors to consent for confidential care (90.8% ± 1.7% approval), while substantially fewer (45.1% ± 4.5%) approved of laws allowing parental notification of this care at the physician's discretion. Most physicians agreed that assured access to confidential care should be a right for adolescents. After taking the survey most physicians (76.6%) felt they needed additional training on confidentiality laws. The provision of confidential care to minors was perceived to be most inhibited by insurance issues, parental concerns/relationships with the family, and issues with the electronic medical record. Physicians are comfortable discussing sensitive issues with adolescents and generally approve of minor consent laws, but lack knowledge about what services a minor can access confidentially. Further research is needed to assess best methods to educate physicians about minors' legal rights to confidential healthcare services.

    Procedures are common in pediatric emergency departments and frequently cause distress from pain and/or anxiety. The objective of this study was to describe the incidence, types, and magnitude of long-term behavior changes after procedures in the emergency setting. This is a descriptive pilot study to determine if children display negative behavioral changes after a minor emergency department procedure (abscess drainage or laceration repair). Behavior change was measured at 1 week by telephone follow-up using the 27-item Post Hospitalization Behavior Questionnaire, a well-validated instrument that measures behavior changes across 6 categories: general anxiety, separation anxiety, anxiety about sleep, eating disturbances, aggression toward authority, and apathy/withdrawal. Significant behavior change was defined as 5 or more negative behavior changes on the 27-item questionnaire. Twenty percent of children who underwent abscess drainage (n = 30) and 20% who underwent laceration repair (n = 30) displayed significant negative behavior change at 1 week. Children who displayed significant negative behavior change tended to be younger (3.6 vs 5.9 years) and trended toward being more likely to have received anxiolysis or sedation (16.7% vs 8.3%). Separation anxiety, sleep difficulties, and aggression toward authority were the most common behavior changes. In this pilot study, a significant percentage of children undergoing common emergency procedures exhibited an appreciable burden of negative behavior change at 1 week; these results demonstrate the need for further rigorous investigation of predictors of these changes and interventions, which can ameliorate these changes.

  17. Principal minors and rhombus tilings

    2014-01-01

    The algebraic relations between the principal minors of a generic n × n matrix are somewhat mysterious, see e.g. Lin and Sturmfels (2009 J. Algebra 322 4121–31). We show, however, that by adding in certain almost principal minors, the ideal of relations is generated by translations of a single relation, the so-called hexahedron relation, which is a composition of six cluster mutations. We give in particular a Laurent-polynomial parameterization of the space of n × n matrices, whose parameters consist of certain principal and almost principal minors. The parameters naturally live on vertices and faces of the tiles in a rhombus tiling of a convex 2n-gon. A matrix is associated to an equivalence class of tilings, all related to each other by Yang–Baxter-like transformations. By specializing the initial data we can similarly parameterize the space of Hermitian symmetric matrices over R,C or H the quaternions. Moreover by further specialization we can parametrize the space of positive definite matrices over these rings. This article is part of a special issue of Journal of Physics A: Mathematical and Theoretical devoted to ‘Cluster algebras mathematical physics’. (paper)

  9. Minor Actinides Recycling in PWRs

    Delpech, M.; Golfier, H.; Vasile, A.; Varaine, F.; Boucher, L.; Greneche, D.

    2006-01-01

    Recycling of minor actinides in current and near future PWR is considered as one of the options of the general waste management strategy. This paper presents the analysis of this option both from the core physics and fuel cycle point of view. A first indicator of the efficiency of different neutron spectra for transmutation purposes is the capture to fission cross sections ratio which is less favourable by a factor between 5 to 10 in PWRs compared to fast reactors. Another indicator presented is the production of high ranking isotopes like Curium, Berkelium or Californium in the thermal or epithermal spectrum conditions of PWR cores by successive neutron captures. The impact of the accumulation of this elements on the fabrication process of such PWR fuels strongly penalizes this option. The main constraint on minor actinides loadings in PWR (or fast reactors) fuels are related to their direct impact (or the impact of their transmutation products) on the reactivity coefficients, the reactivity control means and the core kinetics parameters. The main fuel cycle physical parameters like the neutron source, the alpha decay power, the gamma and neutrons dose rate and the criticality aspects are also affected. Recent neutronic calculations based on a reference core of the Evolutionary Pressurized Reactor (EPR), indicates typical maximum values of 1 % loadings. Different fuel design options for minor actinides transmutation purposes in PWRs are presented: UOX and MOX, homogeneous and heterogeneous assemblies. In this later case, Americium loading is concentrated in specific pins of a standard UOX assembly. Recycling of Neptunium in UOX and MOX fuels was also studied to improve the proliferation resistance of the fuel. The impact on the core physics and penalties on Uranium enrichment were underlined in this case. (authors)

    Suyama, Kenya

    2005-01-01

    Minor actinide (MA) is generated in nuclear fuel during the operation of power reactor. For fuel design, reactivity decrease due to it should be considered. Out of reactors, MA plays key role to define the property of spent fuel (SF) such as α-radioactivity, neutron emission rate, and criticality of SF. In order to evaluate the calculation codes and libraries for predicting the amount of MA, comparison between calculation results and experimentally obtained data has been conducted. In this report, we will present the status of PIE data of MA taken by post irradiation examinations (PIE) and several calculation results. (author)

Se realizaron censos de aves acuáticas en 329 segmentos de habitat de la línea de costa interna del complejo lagunar, desde febrero 2002 hasta febrero 2003. La densidad de aves fue mayor en invierno y otoño en las tres lagunas del área de estudio; de las zonas, la densidad fue mayor en la costa insular; y de los habitats en playa arenosa y dunas pero en los pocos segmentos de sustrato antrópico la densidad fue alta. La diversidad fue significativamente mayor en otoño; en Canal Santo Domingo; en la costa peninsular; y de los habitats en manglar-dunas y manglar. La modificación del habitat natural costero y el disturbio por tránsito de embarcaciones no tuvieron influencia en la densidad o diversidad de aves acuáticas, pero la riqueza acumulada mayor ocurrió en las costas bien conservadas y sin disturbio. El análisis de la composición de especies mostró diferencias entre las asociaciones de Canal Santo Domingo y Bahía Magdalena. El ambiente pelágico y el manglar tuvieron diferencia mayor en la composición de especies con respecto a las asociaciones de los demás habitats, tales diferencias en elencos de especies por habitat sugieren que la comunidad de aves está estructurada de acuerdo a los recursos naturales disponibles de las lagunas, zonas y habitats, en relación con la complejidad estructural de las unidades de paisaje.

    2006-03-01

    To date there have been no studies of how both sex and ethnicity might affect the incidence of both sexual and ethnic harassment at work. This article represents an effort to fill this gap. Data from employees at 5 organizations were used to test whether minority women are subject to double jeopardy at work, experiencing the most harassment because they are both women and members of a minority group. The results supported this prediction. Women experienced more sexual harassment than men, minorities experienced more ethnic harassment than Whites, and minority women experienced more harassment overall than majority men, minority men, and majority women.

In the presence of methionine there was some growth for 2 to 3 days, but by 5 days most of the plants appeared to be dead. When lysine and threonine were added together, there was no growth at all, and the plants were dead after 5 days. This effect of lysine + threonine could be reversed by adding methionine or homoserine to the growth medium. The isolated aspartokinase from Lemna showed inhibition by lysine and higher concentrations of threonine. When these amino acids were added together at low concentrations, there was a concerted inhibition of the aspartokinase. It is suggested that some effects of amino acids on the growth of L. minor can be explained on the basis of a concerted feedback control of aspartokinase. Images PMID:16658324

  15. Work and minor work contracts

    1999-01-01

    The Work and Minor Work contracts are all of the result-oriented type. The work is specified by CERN and the contractor is given full responsibility for its performance. The contracts are thus very similar to supply contracts. The re-tendering of the existing contracts is almost complete, except for some building maintenance contracts. A new cycle of re-tendering for some activities will be launched in the next twelve months. The total estimated expenditure in the year 2000 for the contracts referred to in this document is 27 750 000 Swiss francs at 1999 prices. The Finance Committee is invited: - to approve the proposed expenditure for the extension of contracts for which the estimated amount for the year 2000 exceeds 750 000 Swiss francs, namely those under references 1, 2, 3, 5, 7, 8, 9 and 23, highlighted in Table I; - to take note that all Work and Minor Work contracts have been tendered since 1 January 1994, except the small contracts shown under references 12 and 16 in Table I; - to take note that the ...

    2013-01-01

    The aim of this work was to find palynological markers which permit differentiate honeys from the departments of Boyaca, Cundinamarca, Santander and Magdalena, by its geographical and botanical origin. Melissopalynological analyses were made of 184 honey samples obtained from 131 localities. A discriminant analysis and comparisons between the species composition of honey samples were made to find geo-graphical and botanical origin differences. A total of 297 pollen species distributed in 69 families was found, being Mimosa sp., Cecropia sp., Eucalyptus sp., Piper sp. and Quercus humboldtii the most representatives. The major families were Fabaceae, Asteraceae, Myrtaceae, Rubiaceae, Fagaceae and Melastomataceae. Six honey groups differentiated by its geographical origin were found: Altiplano Cundiboyacense, Medio Chicamocha, Sumapaz, Bajo Chicamocha, Sierra Nevada de Santa Marta and Comunera Province. In a broader scale, honeys from the Andean and sub-Andean regions could be differentiated as well. Between the honey types differentiated by its botanical origin, the most important were monofloral honeys of Trifolium pratense, Coffea arabica, Eucalyptus sp., Inga sp. and Heliocarpus americanus, Asteraceae oligofloral honeys and mixtures of Q. humboldtii honeydew and floral nectar (Eucalyptussp., Brassicaceae Type, Asteraceae). This information in addition to the obtained by physico-chemical and sensorial analysis, may be the basis to acquire honeys' origin denomination.

  18. Minority game with arbitrary cutoffs

    Science.gov (United States)

    Johnson, N. F.; Hui, P. M.; Zheng, Dafang; Tai, C. W.

    1999-07-01

    We study a model of a competing population of N adaptive agents, with similar capabilities, repeatedly deciding whether to attend a bar with an arbitrary cutoff L. Decisions are based upon past outcomes. The agents are only told whether the actual attendance is above or below L. For L∼ N/2, the game reproduces the main features of Challet and Zhang's minority game. As L is lowered, however, the mean attendances in different runs tend to divide into two groups. The corresponding standard deviations for these two groups are very different. This grouping effect results from the dynamical feedback governing the game's time-evolution, and is not reproduced if the agents are fed a random history.

  19. Resistance to minor groove binders.

    Science.gov (United States)

    Colmegna, Benedetta; Uboldi, Sarah; Erba, Eugenio; D'Incalci, Maurizio

    2014-03-01

    In this paper multiple resistance mechanisms to minor groove binders (MGBs) are overviewed. MGBs with antitumor properties are natural products or their derivatives and, as expected, they are all substrates of P-glycoprotein (P-gp). However, a moderate expression of P-gp does not appear to reduce the sensitivity to trabectedin, the only MGB so far approved for clinical use. Resistance to this drug is often related to transcriptional mechanisms and to DNA repair pathways, particularly defects in transcription-coupled nucleotide excision repair (TC-NER). Therefore tumors resistant to trabectedin may become hypersensitive to UV rays and other DNA damaging agents acting in the major groove, such as Platinum (Pt) complexes. If this is confirmed in clinic, that will provide the rationale to combine trabectedin sequentially with Pt derivates.

    Full Text Available Los modelos hidrológicos e hidráulicos han permitido grandes avances en los estudios de las cuencas hidrográficas, la utilización de modelos como HEC RAS y HEC HMS los cuales han recibido una gran acogida por la comunidad mundial de ingenieros que se desempeñan en el área de la meteorología, hidrología, hidráulica y otras áreas relacionadas con el manejo del recurso hídrico. Gracias a sus grandes aproximaciones los modelos de HEC RAS y HEC HMS fueron seleccionados para realizar las modelaciones para determinar el comportamiento hidrológico e hidráulico de la cuenca del río Frío ubicada en el municipio de Zona Bananera, departamento del Magdalena como producto de las inundaciones que se han presentado en los últimos años. En este artículo se expone una cantidad de análisis cuantitativos y cualitativos que posibilitan la obtención de la información de entrada de los modelos de simulación, posteriormente, dicha información fue introducida a los modelos para lograr determinar el comportamiento bajo escenarios extremos a los que la cuenca del río Frío puede ser sometida. De acuerdo con los resultados obtenidos las áreas donde se presentan los principales inconvenientes de carácter hidráulico e hidrológico, se deben principalmente a la configuración geométrica de la batimetría del río y al desarrollo de actividades agrícolas y ganaderas que han generado cambios en el uso del suelo, modificando los números de curva y aumentando la escorrentía hacia los afluentes y finalmente hacia el río principal. Frente a esta situación se relacionan una serie de recomendaciones que buscan corregir el régimen hidrológico y comportamiento hidrodinámico para evitar nuevas inundaciones que pongan en riesgo a la población que se encuentra en las inmediaciones del río Frío en el municipio de la Zona Bananera Departamento del Magdalena.

  2. Energy policy: Comparative effects on minority population groups

    Energy Technology Data Exchange (ETDEWEB)

    Poyer, D.A.; Henderson, L.

    1995-06-01

    For a number of years, analyses of minority household energy demand have been supported by the United States Department of Energy (DOE), Office of Economic Impact and Diversity (formerly the Office of Minority Economic Impact). The intention of these analyses has been to characterize patterns of energy demand by various demographic, regional and socioeconomic groups and to develop analytical tools to assess the distributive impact of energy prices and policy on these groups. The model supports strategic objectives outlined by the Department of Energy to explicitly recognize and promote equity in state public utility commission decisions and to assess the potential impact of federal and state energy policy on demographically diverse groups as reported in the Department`s Annual Energy Outlook and the upcoming National Energy Policy Plan. The legislation mandating the Office of Economic Impact and Diversity had been premised on the assumption that patterns of energy demand for minority households are different from the population as a whole. Determining the validity of this premise and its potential economic impact on different population groups has been a major objective of these analyses. Consequently, the recripriocal impacts of energy policy on demographic groups and energy consumption and expenditure dynamics on policy formulation and strategy is a central objective of these studies. Residential energy demand research has been substantial in the past twenty years. Insightful and useful research has been done in this area. However, none of this research has addressed the potential differences in the residential energy demand structure among various population groups. Recent work does compare energy and electricity demand elasticities for non-Latino Whites, with the demand elasticities for Latinos and Blacks. This research is particularly important for examination of questions related to the economic welfare implications of national energy policy.

    Since the minor planets are believed to consist of primordial matter dating from the time of the formation of the solar system there is great interest in determining their composition. It is therefore necessary to calculate their densities, for which we need accurate masses and sizes. On the rare occasions when a minor planet occults a star, timed observations of the event from a number of observing sites enable an accurate size of the minor planet to be determined. (Auth.)

  10. Major events and minor episodes

    International Nuclear Information System (INIS)

    Amaldi, U.

    2014-01-01

    Bruno Pontecorvo was a freshly graduated twenty one years old physicist when he joined, in the summer of 1934, the research group led by Enrico Fermi. In October the Panisperna boys would make their most important discovery – radioactivity induced by slow neutrons – and shortly thereafter would be parted by personal and historical events. This paper describes some episodes of those early years and of later periods, sketching a portrait of the team: starting from the extraordinary human and scientific experience of via Panisperna, up to the patent negotiations in USA, to which Pontecorvo’s flight to URSS put an end with unexpected consequences; getting to his first return in Italy, allowed by the sovietic government in 1978, on the occasion of the conference celebrating Edoardo Amaldi’s 70. anniversary. That was the first of several encounters of the author of this paper with Bruno Pontecorvo, which are here briefly recounted, as minor episodes giving a personal perspective on the man.

  11. Geology and mineral deposits of an area in the Departments of Antioquia and Caldas (Subzone IIB), Colombia

    Feininger, Tomas; Barrero L., Dario; Castro, Nestor; Hall, R.B.

    1973-01-01

    The Inventario Minero National (IMN), a four-year cooperative geologic mapping and mineral resources appraisal project, was accomplished under an agreement between the Republic of Colombia and the U. S. Agency for International Development from 1964 through 1969. Subzone IIB, consisting essentially of the east half of Zone comprises nearly 20,000 km2 principally in the Department of Antioquia but including also small parts of the Departments of Caldas and Tolima. The rocks in IIB range from Precambrian to Holocene. Precambrian feldspar-quartz gneiss occupies a mosaic of fault-bounded blocks intruded by igneous rocks between the Oto fault and the Rio Magdalena. Paleozoic rocks are extensive, and include lightly metamorphosed graptolite-bearing Ordovician shale at Cristalina, and a major suite of graphitic quartz-mica schist, feldspathic and aluminous gneiss, quartzite, marble, amphibolite, and other rocks. Syntectonic intrusive gneiss included many of the older rocks during a late Paleozoic(?) orogeny, which was accompanied by Abukuma-type metamorphosing from lowermost greenschist to upper amphibolite facies. A Jurassic diorite pluton bounded by faults cuts volcanic rocks of unknown age east of the Otu fault. Cretaceous rocks are major units. Middle Cretaceous carbonaceous shale, sandstone, graywacke, conglomerate, and volcanic rocks are locally prominent. The Antioquian batholith (quartz diorite) of Late Cretaceous age cuts the middle Cretaceous and older rocks. A belt of Tertiary nonmarine clastic sedimentary rocks crops out along the Magdalena Valley. Patches of Tertiary alluvium are locally preserved in the mountains. Quaternary alluvium, much of it auriferous, is widespread in modern stream valleys. Structurally IIB constitutes part of a vast complex synclinorium intruded concordantly by syntectonic catazonal or mesozonal felsic plutons, and by the later epizonal post-tectonic Antioquian batholith. Previously unrecognized major wrench faults are outstanding

    Osuna, Eduardo

    2010-06-01

    One of the pillars of healthcare provision is respect for the autonomy of the patient's wishes, which is given substance by the process of obtaining informed consent. Minors deserve special protection, entitled to basic rights and increasingly autonomous as they develop. In certain situations, minors are deemed matures and able to consent to treatment without the involvement of a parent or guardian. The assessment of competence would be based on the child's functional ability, not on age or outcome of the decision. This manuscript includes a brief analysis of legal perspectives on informed consent of minors, and minors' capacities to make medical decisions. Remaining questions of how to evaluate capacity and balance parental and minor autonomy are explored. Considerations on informed consent in different situations as refusing treatment and termination of pregnancy by female children are analyzed.

  14. Multiple Minority Stress and LGBT Community Resilience among Sexual Minority Men.

    McConnell, Elizabeth A; Janulis, Patrick; Phillips, Gregory; Truong, Roky; Birkett, Michelle

    2018-03-01

    Minority stress theory has widespread research support in explaining health disparities experienced by sexual and gender minorities. However, less is known about how minority stress impacts multiply marginalized groups, such as lesbian, gay, bisexual, and transgender people of color (LGBT POC). Also, although research has documented resilience in the face of minority stress at the individual level, research is needed that examines macro-level processes such as community resilience (Meyer, 2015). In the current study, we integrate minority stress theory and intersectionality theory to examine multiple minority stress (i.e., racial/ethnic stigma in LGBT spaces and LGBT stigma in one's neighborhood) and community resilience (i.e., connection to LGBT community) among sexual minority men of different racial/ethnic groups who use a geosocial networking application for meeting sexual partners. Results showed that Black sexual minority men reported the highest levels of racial/ethnic stigma in LGBT spaces and White sexual minority men reported the lowest levels, with Asian and Hispanic/Latino men falling in between. Consistent with minority stress theory, racial/ethnic stigma in LGBT spaces and LGBT stigma in one's neighborhood were associated with greater stress for sexual minority men of all racial/ethnic groups. However, connection to LGBT community played more central role in mediating the relationship between stigma and stress for White than POC sexual minority men. Results suggest that minority stress and community resilience processes may differ for White and POC sexual minority men. Potential processes driving these differences and implications for minority stress theory are discussed.

  15. Minor actinide transmutation - a waste management option

    International Nuclear Information System (INIS)

    Koch, L.

    1986-01-01

    The incentive to recycle minor actinides results from the reduction of the long-term α-radiological risk rather than from a better utilization of the uranium resources. Nevertheless, the gain in generated electricity by minor actinide transmutation in a fast breeder reactor can compensate for the costs of their recovery and make-up into fuel elements. Different recycling options of minor actinides are discussed: transmutation in liquid metal fast breeder reactors (LMFBRs) is possible as long as plutonium is not recycled in light water reactors (LWRs). In this case a minor actinide burner with fuel of different composition has to be introduced. The development of appropriate minor actinide fuels and their properties are described. The irradiation experiments underway or planned are summarized. A review of minor actinide partitioning from the PUREX waste stream is given. From the present constraints of LMFBR technology a reduction of the long-term α-radiological risk by a factor of 200 is deduced relative to that from the direct storage of spent LWR fuel. Though the present accumulation of minor actinides is low, nuclear transmutation may be needed when nuclear energy production has grown. (orig.)

  16. CRIMINALITY AT MINORS WITH MENTAL DEFICIENCY

    Full Text Available The aim of this paper is to present, from penological aspect, the involvement and structure of recidivism at minors with mental deficiency within the whole area of juvenile criminality in Macedonia. The research covers 62 subjects who pay the penalty in juvenile penitentiary or institutional measure directing to correctional institution for minors. Of the total number of minors who hold one of the above-mentioned sanctions, minors with lower average IQ are presented with 56.4%. The shown involvement is in penological terms (refers to minors who hold institutional measure correctional institution for minors or penalty - juvenile penitentiary which does not mean that this category of juvenile delinquents participate in such percent in the total number of reported, accused and convicted minors. According to the research results it can be concluded that falling behind in intellectual development is an indicator for delinquent behavior but in no case it can be crucial or the most important factor for criminality. Of the total number of juvenile delinquents with intellectual deficit, 80% are repeat offenders in criminal legal sense. It is of great concern that 56% of the under average juvenile delinquents defied the law for the first time before the age of 14 years that is as children.

    Full Text Available The paper analyses the Minority Game and focuses on analysis and computational modelling of several variants (variable payoff, coalition-based and ternary voting of Minority Game using UAREI (User-Action-Rule-Entities-Interface model. UAREI is a model for formal specification of software gamification, and the UAREI visual modelling language is a language used for graphical representation of game mechanics. The URAEI model also provides the embedded executable modelling framework to evaluate how the rules of the game will work for the players in practice. We demonstrate flexibility of UAREI model for modelling different variants of Minority Game rules for game design.

    2006-10-01

    Case records of leishmaniasis of the years 1997 to 2003 of the department of Boyaca showed that since the year 2000 the department experienced an unusual rise in the incidence of cutaneous leishmaniasis that might correspond to an epidemic outbreak in the western region of the department. Age and gender distribution of cases supported a domestic transmission. This research was designed to identify the vectors of cutaneous leishmaniasis in the municipalities of Otanche and Pauna through their presence in dwellings and their natural infection with the same species of Leishmania isolated from patients. Sampling of sand flies was done with CDC traps in and around dwellings. Samples from patients and pooled females of the most abundant species of Lutzomyia were used to identify the parasite by PCR. Monoclonal antibody typing was also used to confirm the identification of the parasite in samples from patients. In both municipalities L. trapidoi was the most abundant anthropophilic species of Lutzomyia indoors and around dwellings. L. hartmanni and L. yuilli were also abundant in Otanche, and L. gomezi and L. panamensis in Pauna. Leishmania (V) panamensis was identified both in patients and in the sand flies: L. yuilli, L. gomezi and L. panamensis.. Our findings prove the presence of infected vectors of Leishmania panamensis within dwellings in the towns of Otanche and Pauna in Western Boyacá. Since L. trapidoi was the most abundant species, it may be considered as the principal vector of Leishmania (V.) panamensis. The evidence of transmission within human dwellings warrants vector control at least in this environment.

The main objective is to highlight the heterogeneity of juvenile migratory phenomenon, achieving a prospective of analyses which focuses not only on international law aimed at protecting minors but also on the flaws of European systems which ignore too often the importance of the superior interests of the child. Mainly the Convention on the Rights of the Child, signed in New York in 1959, provides a generalized protection of minor figure and it represents the legal basis for all rules directed towards children and thus to minor immigrants.

    2013-02-01

    To test Music Marker Theory (MMT) positing that early adolescents' preferences for nonmainstream types of popular music indicate concurrent and later minor delinquency. MMT was tested in a 4-year longitudinal study (n = 309). The results showed that early fans of different types of rock (eg, rock, heavy metal, gothic, punk), African American music (rhythm and blues, hip-hop), and electronic dance music (trance, techno/hardhouse) showed elevated minor delinquency concurrently and longitudinally. Preferring conventional pop (chart pop) or highbrow music (classic music, jazz), in contrast, was not related to or was negatively related to minor delinquency. Early music preferences emerged as more powerful indicators of later delinquency rather than early delinquency, indicating that music choice is a strong marker of later problem behavior. The mechanisms through which music preferences are linked to minor delinquency are discussed within the framework of MMT.

  20. Chest radiography after minor chest trauma

    Energy Technology Data Exchange (ETDEWEB)

    Rossen, B.; Laursen, N.O.; Just, S.

    The results of chest radiography in 581 patients with blunt minor thoracic trauma were reviewed. Frontal and lateral views of the chest indicated pathology in 72 patients (12.4%). Pneumothorax was present in 16 patients; 4 had hemothorax. The physical examination and the results of chest radiography were not in accordance because in 6(30%) of the 20 patients with hemo/-pneumothorax the physical examination was normal. Consequently there is wide indication for chest radiography after minor blunt chest trauma.

    To study the clinical features of minor salivary gland tumors and to discuss the treatment modalities for these tumors. Retrospective analysis of 54 cases with minor salivary gland tumor operated in our hospital from 1997 to 2004. Among 54 cases with minor salivary gland tumors in this series, 16 patients lost of follow up. Among the remaining 38 patients, 2 patients with nasal cavity adenoid cystic carcinoma died of tumor recurrence 2 and 3 years after the surgery respectively, one patient with laryngeal myoepithelial carcinoma died of tumor recurrence 3 years after the surgery and one patient with paranasal sinus mucoepidermoid carcinoma died of recurrence 17 months after the surgery. Two patients with paranasal sinus adenoid cystic carcinoma recurred after the primary surgery and were survived without tumor after salvage surgery. The other patients survived with no tumor recurrence. While different histopathology of minor salivary gland tumors were found in this group, malignant tumors were predominant, accounting for 81.4%. The choice of treatment for minor salivary gland tumors depends upon the location and the histopathology of the tumors. The treatment policy for benign tumors is simple tumor excision, while that for malignant tumors is surgery combined with pre- or post-operative radiation therapy. Complete surgical resection of tumor masses and tumor free margin is essential for successful treatment of malignant minor salivary gland tumors.

    2009-01-01

    One of the strategies to control tobacco is to limit purchase of cigarettes to minors. To understand the attitudes of Italian adults towards regulations to prevent minors from purchasing tobacco products, we added specific questions to the annual survey on smoking in Italy. During March-April 2007, we conducted a survey on smoking on 3,057 subjects representative of the Italian population aged > or = 15 years. Two specific questions were included, one investigating the attitudes towards the proposed legislation prohibiting purchase of tobacco to individuals under 18 years of age (instead of 16 years) as a policy to reduce smoking prevalence and consumption. The second question asked whether the current tobacco sales-to-minors law was observed. Overall, 78% of Italians believed that a restriction of the current tobacco sales-to-minors law could be moderately to extremely effective as a strategy to decrease smoking prevalence and consumption. More than 90% of Italians reported that they had never seen in their lifetime a retailer refusing to sell cigarettes to an adolescent or requesting the minor's identification or age. A restriction of the legislation, increasing to 18 years the minimum age for purchasing tobacco, would limit access to tobacco products by minors, only if adopted together with systematic and effective enforcement measures.

    Full Text Available Studies on the physical and chemical effects of extensive grazing on soils have been performed in Colombia, but the effects of dairy cattle rearing on the biological properties of soils are not well known. The objective of this study was to evaluate microorganisms in 48 soils from livestock farms in the highland and lowland tropics in the Northern and Magdalena Medio subregions of the Department of Antioquia (Colombia. Principal component analysis demonstrated differences in the edaphic compositions of the soils, with increased percentages of root colonization by arbuscular mycorrhizal fungi and the density of microorganisms in farms that have soils with moderate phosphorus and nitrogen contents, low potassium content, and a moderately acidic pH. Agglomerative cluster analysis showed two groups for the highland tropic soils and six groups for the lowland tropic soils based on their population densities and interactions with the studied parameters. These results represent a first attempt to describe the density of microorganisms and the effect of soil physicochemical parameters on colonization by arbuscular mycorrhizal fungi in areas with determinant agroecological conditions, microbial functional diversity, and the presence of mycorrhizal fungi in livestock farm soils in Colombia.

    Lehavot, Keren; Simoni, Jane M

    2011-04-01

    We examined the direct and indirect impact of minority stress on mental health and substance use among sexual minority women. A combination of snowball and targeted sampling strategies was used to recruit lesbian and bisexual women (N = 1,381) for a cross-sectional, online survey. Participants (M age = 33.54 years; 74% White) completed a questionnaire assessing gender expression, minority stressors (i.e., victimization, internalized homophobia, and concealment), social-psychological resources (i.e., social support, spirituality), and health-related outcomes. We used structural equation modeling to test associations among these factors, with gender expression as an antecedent and social-psychological resources as a mediator between minority stress and health. The final model demonstrated acceptable fit, χ²(79) = 414.00, p accounting for significant portions of the variance in mental health problems (56%) and substance use (14%), as well as the mediator social-psychological resources (24%). Beyond indirect effects of minority stress on health outcomes, direct links emerged between victimization and substance use and between internalized homophobia and substance use. Findings indicate a significant impact of minority stressors and social-psychological resources on mental health and substance use among sexual minority women. The results improve understanding of the distinct role of various minority stressors and their mechanisms on health outcomes. Health care professionals should assess for minority stress and coping resources and refer for evidence-based psychosocial treatments. (c) 2011 APA, all rights reserved.

    Full Text Available The breakdown of the former Yugoslavia has resulted in formation of new independent states while the former co-citizens and constitutive people have found themselves in new roles. Some have become a majority while some have become a minority, with an aspiration to affirm the status in the public sphere. As a country with a large numbers of immigrants from the former Yugoslavia, Slovenia is facing a challenge of the confirmation of ethnic pluralism within its borders, along with solutions and appropriate places for 'new' minorities (the usual appellation for ethnic groups formed by the members of the former Yugoslavia, where the Serbs are outnumbering the rest. At the same time, the new minorities face a challenge of constitution foundation of their own associations, that is, formation of their own identity and public affirmation in the new context. This paper discusses these ongoing processes with a special attention to the Serbian ethnic group.

In this way, it came out of the scope of its actions. Leading people in independent media believe that the role of the public service is crucial in protecting national minorities.But the media can not do it alone. First of all, the state must regulate, and respect what it has brought.

  16. The minor collagens in articular cartilage

    DEFF Research Database (Denmark)

    Luo, Yunyun; Sinkeviciute, Dovile; He, Yi

    2017-01-01

    Articular cartilage is a connective tissue consisting of a specialized extracellular matrix (ECM) that dominates the bulk of its wet and dry weight. Type II collagen and aggrecan are the main ECM proteins in cartilage.

    Hickey, Kathryn

    2007-01-01

    In the past, minors were not considered legally capable of making medical decisions and were viewed as incompetent because of their age. The authority to consent or refuse treatment for a minor remained with a parent or guardian. This parental authority was derived from the constitutional right to privacy regarding family matters, common law rule, and a general presumption that parents or guardians will act in the best interest of their incompetent child. However, over the years, the courts have gradually recognized that children younger than 18 years who show maturity and competence deserve a voice in determining their course of medical treatment. This article will explore the rights and interests of minors, parents, and the state in medical decision making and will address implications for nursing administrators and leaders.

    Most of the information in Chile about health and wellbeing of sexual minorities refers to risk behaviors. To assess health and wellbeing in a sample of Chilean homosexual men and women. Spanish versions of the Satisfaction With Life Scale and Outcome Questionnaire-45 (OQ-45) were answered by 191 homosexual women and 256 homosexual men aged 18 to 67 years, from four Chilean cities. Lesbian women have better levels of satisfaction with life and adjustment in personal relationships than homosexual men. Eight percent of respondents had suicidal thoughts in some moment of their life. The information gathered in this work could help in the development of mental health policies for sexual minorities.

    1987-01-01

    The results of chest radiography in 581 patients with blunt minor thoracic trauma were reviewed. Frontal and lateral views of the chest indicated pathology in 72 patients (12.4%). Pneumothorax was present in 16 patients; 4 had hemothorax. The physical examination and the results of chest radiography were not in accordance because in 6(30%) of the 20 patients with hemo/-pneumothorax the physical examination was normal. Consequently there is wide indication for chest radiography after minor blunt chest trauma. (orig.)

    The management of patients with acute transient ischemic attack (TIA) or minor stroke is highly variable. Whether hospitalization of such patients significantly improves short-term clinical outcome is unknown. We assessed the short-term clinical outcome associated with inpatient versus outpatient management of patients with TIA or minor stroke. We evaluated a consecutive series of patients with acute TIA or minor ischemic stroke (NIH Stroke Scale score ≤ 3) presenting to a single emergency department (ED). We randomized patients to either hospital-based or outpatient-based management. All patients underwent interview and examination 7-10 days following the index event. This study included 100 patients, 41 with TIA and 59 with minor stroke. Nineteen (46%) of the TIA patients and 29 (49%) of the minor stroke patients randomized to hospital management, and the remaining 22 TIA patients and 30 minor stroke patients randomized to outpatient-based management. In the patients with a minor stroke, neurologic worsening occurred in 6 out of 29 (21%) in the inpatient arm compared with 3 out of 30 (10%) in the outpatient arm ( p = 0.3). In none of these cases was acute interventional therapy or need for urgent admission considered medically appropriate. In the patients with a TIA, recurrence of a TIA occurred in 2 out of 19 (11%) in the inpatient arm compared with 2 out of 22 (9%) in the outpatient arm ( p = 1). None of the patients with a TIA randomized to the inpatient arm experienced a stroke compared with 1 out of 22 in the outpatient arm ( p = 1). There were no deaths in either group. Routine hospitalization of all patients with TIA or minor ischemic stroke may not positively affect short-term clinical outcome.

    To investigate whether past-30 day illicit drug use among sexual minority youth was more common in neighborhoods with a greater prevalence of hate crimes targeting lesbian, gay, bisexual, and transgender (LGBT, or sexual minority) individuals. We used a population-based survey of public school youth in Boston, Massachusetts, consisting of 1292 9th-12th grade students from the 2008 Boston Youth Survey Geospatial Dataset (sexual minority n=108). Data on LGBT hate crimes involving assaults or assaults and battery between 2005 and 2008 were obtained from the Boston Police Department and linked to youths' residential address. Youth reported past-30 day use of marijuana and other illicit drugs. Wilcoxon-Mann-Whitney tests and corresponding p-values were computed to assess differences in substance use by neighborhood-level LGBT assault hate crime rate among sexual minority youth (n=103). The LGBT assault hate crime rate in the neighborhoods of sexual minority youth who reported current marijuana use was 23.7 per 100,000, compared to 12.9 per 100,000 for sexual minority youth who reported no marijuana use (p=0.04). No associations between LGBT assault hate crimes and marijuana use among heterosexual youth (p>0.05) or between sexual minority marijuana use and overall neighborhood-level violent and property crimes (p>0.05) were detected, providing evidence for result specificity. We found a significantly greater prevalence of marijuana use among sexual minority youth in neighborhoods with a higher prevalence of LGBT assault hate crimes. These results suggest that neighborhood context (i.e., LGBT hate crimes) may contribute to sexual orientation disparities in marijuana use. Copyright © 2013 Elsevier Ireland Ltd.

  11. A Department of Atmospheric and Planetary Sciences at Hampton University

    2006-12-01

    With this presentation we discuss the status of plans for a Department of Atmospheric and Planetary Sciences at Hampton University. Hampton University is a privately endowed, non-profit, non-sectarian, co-educational, and historically black university with 38 baccalaureate, 14 masters, and 4 doctoral degree programs. The graduate program in physics currently offers advanced degrees with concentration in Atmospheric Science. The 10 students now enrolled benefit substantially from the research experience and infrastructure resident in the university's Center for Atmospheric Sciences (CAS), which is celebrating its tenth anniversary. Promoting a greater diversity of participants in geosciences is an important objective for CAS. To accomplish this, we require reliable pipelines of students into the program. One such pipeline is our undergraduate minor in Space, Earth, and Atmospheric Sciences (SEAS minor). This minor concentraton of study is contributing to awareness of geosciences on the Hampton University campus, and beyond, as our students matriculate and join the workforce, or pursue higher degrees. However, the current graduate program, with its emphasis on physics, is not necessarily optimal for atmospheric scientists, and it limits our ability to recruit students who do not have a physics degree. To increase the base of candidate students, we have proposed creation of a Department of Atmospheric and Planetary Sciences, which could attract students from a broader range of academic disciplines. The revised curriculum would provide for greater concentration in atmospheric and planetary sciences, yet maintain a degree of flexibility to allow for coursework in physics or other areas to meet the needs of individual students. The department would offer the M.S. and Ph.D. degrees, and maintain the SEAS minor. The university's administration and faculty have approved our plan for this new department pending authorization by the university's board of trustees, which will

    OAK-B135 Minority Undergraduate Training for Energy-Related Careers (MUTEC). First, all the co-investigators would like to thank the Department of Energy's Minority Impact Office for awarding FIU with the MUTEC grant for the past five years. We believe it has made a difference, especially in the creation of a new, streamlined curriculum that began with the Mechanical Engineering Program and has now become college wide. Second, we have given 774 students an introduction to engineering, something that did not exist 3 years ago. Third, we have given FLAME the opportunity to participate in this program through the equivalent introduction to engineering course. Over 150 of those students have participated and have a 100% record of completing the program once, they start. Over 80% of those students have gone on to college. Fourth, we have aided 32 undergraduates continue in their engineering studies. Of those half have already graduated, and half of those have gone on to graduate school. One of these graduate school students has graduated with an MSME and another has won an NSF Scholarship. Fifth, we have created a bank of 51 2-hour tapes in 10 science and engineering science areas and covered the spectrum of math courses from geometry/trigonometry to differential equations. Sixth, we have created two examinations for use in preparation for entry into the engineering programs and in preparation for the EIT. Seventh, we have created a streamlined curriculum and four options, two of which are energy related. From these points, we believe that the program was very successful and for that we wish to thank the Department of Energy and specifically Ms. Estela Romo for her unwavering support

The influence of the social networks like instrument of communication is not exempt from risks for the quantity of information that is facilitated and is shared. The lack of a specific regulation that he contemplates from the point of view of the Law which is the protection that a minor must have, does that there take place situations of abandonment of the rights of the same ones.The opportunity of regulation has been left to escape in the future law of protection of the infancy, nowadays in phase of preliminary design, since it does not refer to the social networks since it had been desirable. The current procedure as for minors, as well as those of protection of information, between others, do not turn out to be sufficient to contemplate all the situations of risk that can be given in the above mentioned area. In the present work we propose to think on minors and social networks raising some legal questions, and trying to contribute some response to the problematics that appears in the juridical area.

  9. Partitioning and Transmutation of minor actinides

    Koch, L.; Wellum, R.

    1991-01-01

    The partitioning of minor actinides from spent fuels and their transmutation into short-lived fission products has been the topic of two dedicated meetings organized jointly by the European Commission and the OECD. The conclusion of the last meeting in 1980, in short, was that partitioning and transmutation of minor actinides, especially in fast reactors, seemed possible. However, the incentive, which would be a reduction of the radiological hazard to the public, was too small if long-lived fission products were not included. Furthermore this meeting showed that minor actinide targets or possible nuclear fuels containing minor actinides for transmutation had not yet been developed. The European Institute for Transuranium Elements took up this task and has carried it out as a small activity for several years. Interests expressed recently by an expert meeting of the OECD/NEA (Paris, 25 April 1989), which was initiated by the proposed Japanese project Omega, led us to the conclusion that the present state of knowledge should be looked at in a workshop environment. Since the Japanese proposal within the project Omega is based on a broader approach we needed this evaluation to assess the relevance of our present activity and wanted to identifiy additional studies which might be needed to cover possible future demands from the public. This workshop was therefore organized, and participants active in the field from EC countries, the USA and Japan were invited

  10. Multiculturalism and legal autonomy for cultural minorities

    Directory of Open Access Journals (Sweden)

    Morten Ebbe Juul Nielsen

    2013-11-01

    Full Text Available Does multiculturalism imply that certain cultural minorities – nomos groups, whose cultural conceptions extend in important ways into views about the law – should have forms of legal autonomy that go beyond normal multicultural accommodations such as exemptions and special protection? In other words: should we allow «minority jurisdictions» for multicultural reasons and give certain minorities powers of legislation and adjudication on certain issues? The paper sketches how one might arrive at such a conclusion given some standard multicultural reasoning, and then proceeds by examining eight key rejoinders to such a proposal. None of these rejoinders provide by themselves knockdown arguments against extending multicultural rights to forms of legal autonomy, but together they do provide a basis for some skepticism about the cogency and desirability of at least more ambitious forms of legal autonomy for cultural minorities within a liberal framework.http://dx.doi.org/10.5324/eip.v7i2.1798

    2016-09-01

    Full Text Available The article tries to explore the practical application of the soft law, in concrete terms, the documents adopted by the Organization for Security and Co-operation in Europe, referring to the models of participation of national minorities in public life in the case of Bosnia and Herzegovina. The objective of the research was to assess the legal and political grounds for functioning national minority councils as participation and consultative mechanisms, scope of responsibilities and capacities in relation to their effectiveness and impact and to identify relevant good practices on such mechanisms. The political and decision-making structures in Bosnia and Herzegovina demonstrated lack of actual commitment to the realization of the rights of minorities referring to participation in decision-making processes. Bearing in mind formal position within parliaments, visibility, and a significant promotional capacity for presence in the public sphere, the councils on national minorities may represent a significant body and channel for the minority – majority dialogue. However, at the moment, the national minority councils’ capacity to ensure participation of national minorities in Bosnian political life and their influence in decision-making process remains insufficient. In general, the consultative mechanisms, within their mandated responsibilities, have had insignificant and minimal impact on the practical, political and legislative segment.

We describe sextortion incidents from a large sample of victims (n = 1,385) and examine whether incidents occurring to minors (n = 572) are more or less serious than those experienced by young adults (n = 813). We ran advertising campaigns on Facebook to recruit victims of sextortion, ages 18-25, for an online survey. We use cross tabulations and logistic regression to analyze incidents that began when 18- and 19-year-old respondents were minors (ages 17 and younger) and compare them with incidents that began at ages 18-25 years. Most minor victims were female (91%) and aged 16 or 17 when incidents started (75%). Almost 60% of respondents who were minors when sextortion occurred knew perpetrators in person, often as romantic partners. Most knowingly provided images to perpetrators (75%), but also felt pressured to do so (67%). About one-third were threatened with physical assaults and menaced for >6 months. Half did not disclose incidents, and few reported to police or websites. Perpetrators against minors (vs. adults) were more likely to pressure victims into producing initial sexual images, demand additional images, threaten victims for >6 months, and urge victims to harm themselves. Sextortion incidents were serious victimizations, and often co-occurred with teen dating violence. We describe resources so that practitioners can help victims find support and legal advice and remove posted images. Copyright © 2017 The Society for Adolescent Health and Medicine.

    2004-01-01

    Over the past 30 years the importance of vaccines for minor use and minor species has changed for multinational animal health companies. The major reasons for this are being reviewed, with a particular focus on technical, financial and business aspects. Key regulatory obstacles to the development of new products for minor uses and minor species are identified, and examples of vaccines falling into the various categories are provided. A number of proposals are offered with the intention of resolving the medicines availability problem between all the stakeholders involved. Finally, based on the presented scientific and regulatory considerations, ideas are shared as to where the legal and economical framework would need to change to reach a viable solution.

    To report on an Israeli academic nursing project, aimed at supporting the integration of Ethiopian immigrants into nursing studies. The representation of ethnic minorities within nursing is crucial for the provision of efficient care in diverse societies. Nevertheless, successful integration of minority students in nursing programs is not a simple task and needs developing support systems that will attract and retain students from minorities. Ethiopian Jewish immigrants and their descendants in Israel form a community of 120,000 people. Their participation in the national workforce is low, as well as their average income. The paper is based on formative evaluation, using action research, of an academic nursing program in Israel. Four main strategies identify this project: (1) a policy of institutional commitment, (2) personal relations with staff, (3) personal tutoring, and (4) cultural safety education. The project has reached success in terms of attraction, retention and students' satisfactions. The project's two main challenges, which need further concern, are: (1) giving support without labelling and (2) supporting without creating dependency. CONCLUSIONS AND INTERNATIONAL POLICY IMPLICATIONS: Appropriate strategies can enable success of minority students. Nevertheless, the amount of support needed for such programs raises two major questions: (1) To what extent should individual nursing departments be expected to bear solutions to this widely experienced problem? (2) How does focusing on one minority affect cultural safety of the overall group? © 2013 The Authors. International Nursing Review © 2013 International Council of Nurses.

    Full text: The Department's continuing interest is centered on the mechanisms of mutagenesis and DNA repair. Part of the studies concerns the effects of the interdependence of mutator and antimutator genes on the response of E. coli cells to various mutagens. The phenomenon of mutation frequency decline (MFD) was studied and recently distinct response of this system to UV light and to alkylating agents was shown. Studies on the isfA gene, which is involved in the regulation of the SOS response, including its precise localization on the bacterial chromosome, were continued. Also, studies on the mechanism of DNA replication-independent mutagenesis in lambda phage were continued. Halogen light mutagenesis and the role of the hem gene in the near UV and UVA irradiation mutagenesis were investigated. New experimental approaches were adapted to study adaptive mutations. Another part of the studies was focused on the relation between the structure of DNA bases adducts and their coding and mutagenic properties, as well as their properties as substrates for DNA repair enzymes. These studies include instrumental methods, such as NMR, MS, HPLC and GC/MS, to investigate structure and the kinetics of formation and excision of adducts, and organic chemistry methods to synthesize adducts. The coding and mutagenic properties of several oxidized and alkylated bases (including imidazole-ring opened purines) were determined by employing in vitro enzymatic and phage/bacteria systems. The sites of reaction of chloroacetaldehyde, a metabolite of carcinogenic vinyl chloride, with a fragment of human p53 gene, were studied using the method of polymerase fingerprint analysis. Ethenoadducts, the products of the reaction of chloroacetaldehyde with adenine and cytosine, and also products of solvolytic degradation of ethenoadenine, were studied as substrates of various DNA glycosylases. Several purine and pyrimidine derivatives were synthesized and tested as inhibitors of DNA glycosylases

    According to the family stress model (Conger & Donnellan, 2007), low socioeconomic status (SES) predicts less-than-optimal parenting through family stress. Minority families generally come from lower SES backgrounds than majority families, and may experience additional stressors associated with their minority status, such as acculturation stress. The primary goal of this study was to test a minority family stress model with a general family stress pathway, as well as a pathway specific to ethnic minority families. The sample consisted of 107 Turkish-Dutch mothers and their 5- to 6-year-old children, and positive parenting was observed during a 7-min problem-solving task. In addition, mothers reported their daily hassles, psychological distress, and acculturation stress. The relation between SES and positive parenting was partially mediated by both general maternal psychological stress and maternal acculturation stress. Our study contributes to the argument that stressors specific to minority status should be considered in addition to more general demographic and family stressors in understanding parenting behavior in ethnic minority families.

    Background Sexual minorities are more likely than heterosexuals to engage in unhealthy eating behaviors. Purpose To examine sexual minority stressors and internalizing symptoms as predictors of unhealthy eating behaviors among sexual minority youth. Methods We used longitudinal data from 1461 sexual minority youth in the Growing Up Today Study, across ages 14-28 years. We hypothesized that sexual minority stressors would predict unhealthy eating behaviors, in part due to internalizing symptoms. Linear regression models fit via generalized estimating equations were stratified by gender and sexual orientation. Results Significant positive and inverse associations between stressors and eating behaviors were detected among females and males, with more significant associations among females. Associations were attenuated by up to 71% for females and 12% for males when internalizing symptoms were added to the models. Conclusions Sexual minority stressors predicted unhealthy eating behaviors overall and more so for some sexual orientation and gender groups; associations were partially explained by internalizing symptoms. The conceptual model appears to best describe the experiences of bisexual females. Findings have clinical implications for adolescent health. PMID:26156678

    While much attention has been directed at improving the quality of care at the end of life, few studies have examined what determines a good death in different individuals. We sought to identify common domains that characterize a good death in a diverse range of community-dwelling individuals, and to describe differences that might exist between minority and non-minority community-dwelling individuals' views. Using data from 13 focus groups, we identified 10 domains that characterize the quality of the death experience: 1) physical comfort, 2) burdens on family, 3) location and environment, 4) presence of others, 5) concerns regarding prolongation of life, 6) communication, 7) completion and emotional health, 8) spiritual care, 9) cultural concerns, 10) individualization. Differences in minority compared to non-minority views were apparent within the domains of spiritual concerns, cultural concerns, and individualization. The findings may help in efforts to encourage more culturally sensitive and humane end-of-life care for both minority and non-minority individuals.

    Full Text Available Abstract Previous studies about unaccompanied refugee minors (URMs showed that they are a highly vulnerable group who have greater psychiatric morbidity than the general population. This review focuses on mental health issues among URMs. Articles in databases PsycINFO, Medline and PubMed from 1998 to 2008 addressing this topic were reviewed. The literature had a considerable emphasis on the assessment of PTSD symptoms. Results revealed higher levels of PTSD symptoms in comparison to the norm populations and accompanied refugee minors. In several studies, age and female gender predicted or influenced PTSD symptoms. The existing literature only permits limited conclusions on this very hard to reach population. Future research should include the analysis of long-term outcomes, stress management and a more thorough analysis of the whole range of psychopathology. Additionally, the development of culturally sensitive norms and standardized measures for diverse ethnic groups is of great importance.

    The purpose of this study was to examine the relationships of sexual minority youth and their siblings. The participants were 56 lesbian, gay, bisexual, or transgender individuals ranging in age from 18 to 24 years, who reported information about a total of 107 siblings. Respondents completed a demographic data questionnaire as well as adapted versions of the Sibling Closeness Scale (SCS) and the Sibling Approval of Sexual Behavior Scale (SASBS) to describe their relationship with each of their siblings. Analyses examined birth order and gender in relation to outness to siblings as well as sibling closeness and approval. Results provide information about disclosure of LGBT status to siblings, elements of closeness and acceptance in sibling relationships of sexual minority youth, and the significance of gender and birth order in these sibling relationships.

    2015-07-01

    Transmutation of radioactive waste, the legacy of nuclear energy use, gains rising interest. This includes the development of facilities able to transmute minor actinides (MA) into stable or short-lived isotopes before final disposal. The most common proposal is to use a double-strata approach with accelerator-driven-systems (ADS) for the efficient transmutation of MA and power reactors to dispose plutonium. An ADS consists of a sub-critical core that reaches criticality with neutrons supplied by a spallation target. An MCNP model of the ADS system Multi Purpose Research Reactor for Hightech Applications will be presented. Depletion calculations have been performed for both standard MOX fuel and transmutation fuel with an increased content of minor actinides. The resulting transmutation rates for MAs are compared to published values. Special attention is given to selected fission products such as Tc-99 and I-129, which impact the radiation from the spent fuel significantly.

    The Primary objective of the proposed project is to apply and extend the latest advancements in LWR fuel management optimization to the design of advanced boiling water reactor (BWR) fuel assemblies specifically for the recycling of minor actinides (MAs). A top-level objective of the Advanced Fuel Cycle Systems Analysis program element of the DOE NERI program is to investigate spent fuel treatment and recycling options for current light water reactors (LWRs). Accordingly, this project targets to expand the traditional scope of nuclear fuel management optimization into the following two complementary specific objectives: (1) To develop a direct coupling between the pin-by-pin within-bundle loading control variables and core-wide (bundle-by-bundle) optimization objectives, (2) to extend the methodology developed to explicitly encompass control variables, objectives, and constraints designed to maximize minor actinide incineration in BWR bundles and cycles. The first specific objective is projected to 'uncover' dormant thermal margin made available by employing additional degrees of freedom within the optimization process, while the addition of minor actinides is expected to 'consume' some of the uncovered thermal margin. Therefore, a key underlying goal of this project is to effectively invest some of the uncovered thermal margin into achieving the primary objective.

    The earth is warming, and it is warming quickly. Epidemiological studies have demonstrated that global warming is correlated with the frequency of pollen-induced respiratory allergy and allergic diseases. There is a body of evidence suggesting that the prevalence of allergic diseases induced by pollens is increasing in developed countries, a trend that is also evident in the Mediterranean area. Because of its mild winters and sunny days with dry summers, the Mediterranean area is different from the areas of central and northern Europe. Classical examples of allergenic pollen-producing plants of the Mediterranean climate include Parietaria, Olea and Cupressaceae. Asia Minor is a Mediterranean region that connects Asia and Europe, and it includes considerable coastal areas. Gramineae pollens are the major cause of seasonal allergic rhinitis in Asia Minor, affecting 1.3-6.4 % of the population, in accordance with other European regions. This article emphasizes the importance of global climate change and anticipated increases in the prevalence and severity of allergic disease in Asia Minor, mediated through worsening air pollution and altered local and regional pollen production, from an otolaryngologic perspective.

  15. Solar-wind minor ions: recent observations

    Bame, S.J.

    1982-01-01

    During the years following the Solar Wind Four Conference at Burghausen our knowledge of the solar wind ion composition and dynamics has grown. There have been some surprises, and our understanding of the evolution of the solar wind has been improved. Systematic studies have shown that the minor ions generally travel with a common bulk speed and have temperatures roughly proportional to their masses. It has been determined that the 3 He ++ content varies greatly; 3 He ++ / 4 He ++ ranges from as high as 10 2 values to below 2 x 10 - 4 . In some solar wind flows which can be related to energetic coronal events, the minor ions are found in unusual ionization states containing Fe 16 + as a prominent ion, showing that the states were formed at unusually high temperatures. Unexpectedly, in a few flows substantial quantities of 4 He + have been detected, sometimes with ions identifiable as O 2 + and O 3 + . Surprisingly, in some of these examples the ionization state is mixed showing that part of the plasma escaped the corona without attaining the usual million-degree temperatures while other parts were heated more nearly in the normal manner. Additionally, detailed studies of the minor ions have increased our understanding of the coronal expansion. For example, such studies have contributed to identifying near equatorial coronal streamers as the source of solar wind flows between high speed streams

    Full text: The activities of Department was engaged in the selected topics in nuclear fission reactor science and engineering. Present and future industry competitiveness, economic prosperity and living standards within the world are strongly dependent on maintaining the availability of energy at reasonable prices and with security of supply. Also, protection of man and the environment from the harmful effects of all uses of energy is an important element of the quality of life especially in Europe. It is unrealistic to assume that the technology for renewable (hydro, wind, solar and biomass) available within a 20-30 year perspective could provide the production capacity to replace present use of nuclear power and at the same time substantially reduce the use of fossil fuels, especially when considering that energy demand in industrialized countries can be expected to continue to increase even within a framework of overall energy conservation and continued improvement of efficiency in energy usage. In the area of nuclear fission, we continue support to maintain and develop the competence needed to ensure the safety of existing and future reactors and other nuclear installations. In addition support is given to explore the potential for improving present fission technology from a sustainable development point of view.

    Sexual minority youth (youth who are attracted to the same sex or endorse a gay/lesbian/bisexual identity) report significantly higher rates of depression and suicidality than heterosexual youth. The minority stress hypothesis contends that the stigma and discrimination experienced by sexual minority youth create a hostile social environment that can lead to chronic stress and mental health problems. The present study used longitudinal mediation models to directly test sexual minority-specific victimization as a potential explanatory mechanism of the mental health disparities of sexual minority youth. One hundred ninety-seven adolescents (14-19 years old; 70 % female; 29 % sexual minority) completed measures of sexual minority-specific victimization, depressive symptoms, and suicidality at two time points 6 months apart. Compared to heterosexual youth, sexual minority youth reported higher levels of sexual minority-specific victimization, depressive symptoms, and suicidality. Sexual minority-specific victimization significantly mediated the effect of sexual minority status on depressive symptoms and suicidality. The results support the minority stress hypothesis that targeted harassment and victimization are partly responsible for the higher levels of depressive symptoms and suicidality found in sexual minority youth. This research lends support to public policy initiatives that reduce bullying and hate crimes because reducing victimization can have a significant impact on the health and well-being of sexual minority youth.

    Lesbian, gay, and bisexual (LGB) individuals report higher levels of depression and anxiety than heterosexual people. Genetic factors may be a 'common cause' of sexual minority status and psychological distress. Alternatively, these may be correlated because of non-genetic environmental factors (e.g. minority stressors). This study investigated minority stressors and distress in monozygotic twins discordant for sexual minority status. This design provides a test of the role of non-shared environmental factors while minimizing differences due to genetics. Thirty-eight twin pairs in which one was heterosexual and the other was LGB completed a survey. Differences between twin pairs in minority stressors, rumination, psychological distress, and gender non-conformity were examined. Associations between these variables were also tested. Although there were no significant group differences for distress, LGB twins had higher rumination, a vulnerability factor for distress, than heterosexual co-twins. LGB twins also had higher scores than heterosexual co-twins on expectations of rejection, active concealment, self-stigma, prejudice events, childhood gender non-conformity, and lower scores on sexual orientation disclosure. Differences between twin pairs in rumination were positively associated with differences in acceptance concerns and self-stigma. Finally, self-stigma was positively associated with rumination in the full sample of heterosexual co-twins and microaggressions were positively associated with rumination when looking at exclusively heterosexual co-twins. These results support environmental factors as a causal explanation for disparities in rumination between LGB and heterosexual individuals. These factors likely include minority stressors. Rumination may also be associated with minority stressors in heterosexual MZ co-twins of LGB individuals.

    Our aim was to assess: (1) medical trainee and practicing physician awareness about domestic sex trafficking of minors; and (2) whether respondents believe that awareness of trafficking is important to their practice. We designed an anonymous electronic survey, and a convenience sample was collected from June through October 2013. Voluntary participants were 1648 medical students, residents, and practicing physicians throughout the United States. Data were analyzed for correlations between study cohort characteristics and: (1) agreement with the statement: "knowing about sex trafficking in my state is important to my profession"; (2) knowledge of national statistics regarding the sex trafficking of minors; and (3) knowledge of appropriate responses to encountering a trafficked victim. More practicing physicians than residents or medical students: (1) agreed or strongly agreed that knowledge about human trafficking was important to their practice (80.6%, 71.1%, and 69.2%, respectively; P = .0008); (2) correctly estimated the number of US trafficked youth according to the US Department of State data (16.1%, 11.7%, and 7.9%, respectively; P = .0011); and (3) were more likely to report an appropriate response to a trafficked victim (40.4%, 20.4%, and 8.9%, respectively; P = .0001). Although most medical trainees and physicians place importance on knowing about human trafficking, they lack knowledge about the scope of the problem, and most would not know where to turn if they encountered a trafficking victim. There exists a need for standardized trafficking education for physicians, residents, and medical students. Copyright © 2015 North American Society for Pediatric and Adolescent Gynecology.

  10. Russian Minorities in the Former USSR

    Directory of Open Access Journals (Sweden)

    Ángel Pérez González

    2000-12-01

    Full Text Available The end of the Soviet Empire has brought out the importance of the nationalities problem and the contradictory results produced by the various formulas applied since 1922 for resolving it. Two characteristics conditioned the evolution of this problem in the Soviet Union: the choice of a territorial model which would give a important role to the Empire’s non-Russian peoples; and the contradiction between the theoretical base established by Lenin and Stalin for solving the problem and actual practice, which followed traditional channels. The result was a new territorial structure endowed with the external elements characteristic of a state but cancelled out by the superiority of a party and by a policy ofprotecting minorities deliberately designed to make the new national entities nonviable. The lack of an adequately institutionalized state was at the root, of the virtual disappearance, after the collapse of the Communist Party, of links between the center and the periphery, a situation that nationalism, where it existed, exploited to gain powerand that governing minorities, meaningless outside the framework created by the USSR, exploited to stay in power. The result was none other than the appearance of new ethnically heterogeneous states with imprecise borders, bereft of the systems of interethnic equilibriumthe Soviet administration had created, and willing to consolidate their independence and identity at the expense of minorities such as the Russians, which have been discriminated against at times and excluded from political and cultural life at others. This phenomenonhas reduced the chances for the new states’ integration on an international level, placed a burden on the incipient democratic systems and made for tense relations with Russia.

  11. Operational safety evaluation for minor reactor accidents

    International Nuclear Information System (INIS)

    Wang, O.S.

    1981-01-01

    The purpose of this paper is to address a concern of applying conservatism in analysing minor reactor incidents. A so-called ''conservative'' safety analysis may exaggerate the system responses and result in a reactor scram tripped by the reactor protective system (RPS). In reality, a minor incident may lead the reactor to a new thermal hydraulic steady-state without scram, and the mitigation or termination of the incident may entirely depend on operator actions. An example on a small steamline break evaluation for a pressurized water reactor recently investigated by the staff at the Washington Public Power Supply System is presented to illustrate this point. A safety evaluation using mainly the safety-related systems to be consistent with the conservative assumptions used in the Safety Analysis Report was conducted. For comparison, a realistic analysis was also performed using both the safety- and control-related systems. The analyses were performed using the RETRAN plant simulation computer code. The ''conservative'' safety analysis predicts that the incident can be turned over by the RPS scram trips without operator intervention. However, the realistic analysis concludes that the reactor will reach a new steady-state at a different plant thermal hydraulic condition. As a result, the termination of the incident at this stage depends entirely on proper operator action. On the basis of this investigation it is concluded that, for minor incidents, ''conservative'' assumptions are not necessary, sometimes not justifiable. A realistic investigation from the operational safety point of view is more appropriate. It is essential to highlight the key transient indications for specific incident recognition in the operator training program

    D'hulst, R.; Rodgers, G. J.

    2000-04-01

    We investigate the dynamics of the choice of an active strategy in the minority game. A history distribution is introduced as an analytical tool to study the asymmetry between the two choices offered to the agents. Its properties are studied numerically. It allows us to show that the departure from uniformity in the initial attribution of strategies to the agents is important even in the efficient market. Also, an approximate expression for the variance of the number of agents at one side in the efficient phase is proposed. All the analytical propositions are supported by numerical simulations of the system.

  17. ISLAM AND MINORITIES: Managing Identity in Malaysia

    Directory of Open Access Journals (Sweden)

    Ahmad Suaedy

    2010-02-01

    Full Text Available The Malaysian general election in March 2008 raised an interesting and new phenomenon. For the first time since independence in 1957, the ruling alliance known as the National Front (Barisan Nasional, BN failed to secure two thirds of seats in parliament and lost control of five of Malaysia’s 13 states. This was due to the challenge presented by the new opposition alliance known as the Alternative Front (Barisan Alternatif, BA or the People’s Alliance (Pakatan Rakyat, PK which won more than 36% of seats in parliament and gained control of the five states. In the 2004 election, BN secured the largest ever percentage of seats in parliament with 91%. What is interesting is that it seems that this significant increase in support for the opposition is  due to their offer to change the way minorities and ethnicity is managed. They  propose a move from “Bumiputera Supremacy”, or affirmative action for the approximately 65% of “Bumiputera” Malaysians (the rest being largely of Chinese or Indian ethnicity, to “The People’s Supremacy”, which involves eradicating affirmative action based on ethnicity, basing it instead on need, for  instance need due to poverty. This would potentially increase the likelihood  of justice and equality for all ethnic or racial groups. This paper connects the phenomenon of change, as seen in the about turn in the results between the  2004 and 2008 elections, to the more global trend in which minorities are standing up to demand their rights in this era of globalization, and to the challenge multiculturalism presents to parts of the Muslim world such as Malaysia. Malaysia, a Muslim majority nation that has formally declared Islam the official state religion with Yang di-Pertuan Agong (the King as  Head of the State and symbol of Islam, is one example, though not necessarily  representative, of how Islam and Muslims manage minorities and identity or  multiculturalism within the process of globalization

  20. Future goal setting, task motivation and learning of minority and non-minority students in Dutch schools.

    Andriessen, Iris; Phalet, Karen; Lens, Willy

    2006-12-01

    Cross-cultural research on minority school achievement yields mixed findings on the motivational impact of future goal setting for students from disadvantaged minority groups. Relevant and recent motivational research, integrating Future Time Perspective Theory with Self-Determination Theory, has not yet been validated among minority students. To replicate across cultures the known motivational benefits of perceived instrumentality and internal regulation by distant future goals; to clarify when and how the future motivates minority students' educational performance. Participants in this study were 279 minority students (100 of Turkish and 179 of Moroccan origin) and 229 native Dutch students in Dutch secondary schools. Participants rated the importance of future goals, their perceptions of instrumentality, their task motivation and learning strategies. Dependent measures and their functional relations with future goal setting were simultaneously validated across minority and non-minority students, using structural equation modelling in multiple groups. As expected, Positive Perceived Instrumentality for the future increases task motivation and (indirectly) adaptive learning of both minority and non-minority students. But especially internally regulating future goals are strongly related to more task motivation and indirectly to more adaptive learning strategies. Our findings throw new light on the role of future goal setting in minority school careers: distant future goals enhance minority and non-minority students' motivation and learning, if students perceive positive instrumentality and if their schoolwork is internally regulated by future goals.

  3. Trabectedin – the DNA minor groove binder

    Directory of Open Access Journals (Sweden)

    G. A. Belitsky

    2015-01-01

    Full Text Available Trabectedin (ET-743, Yondelis is an alkaloid that was originally isolated from the Caribbean Sea squirt, Ecteinascidia turbinata and is now produced synthetically. Its chemical structure consists in three fused tetrahydroisoquinoline rings. Two of them, A and B, binds covalently to guanine residues in the minor groove of the DNA double helix to bend the molecule toward the major groove and the third ring C protrudes from the DNA duplex, apparently allowing interactions with several nuclear proteins. Binding to the minor groove of DNA, trabectedin trigger a cascade of events that interfere with several transcription factors, DNA binding proteins, and DNA repair pathways in particular nucleotide excision repair. It acts both as a DNA-alkylating drug and topoisomerase poison. Trabectedin-DNA adduct traps the nucleotide excision repair proteins repairing the DNA damage in transcribing genes and induces DNA strand breaks. Cells deficient in homologous recombination pathway which repairs these double-strand breaks show increased sensitivity to trabectedin. The most sensitive of them were myxoid liposarcomas. Trabectedin is also effective in chemotherapy-experienced patients with advanced, recurrent liposarcoma or leiomyosarcoma as well as in women with ovarian cancer and breast cancer with BRCAness phenotype. Besides of tumor cells Trabectedin inhibits inflammatory cells by affecting directly monocytes and tumorassociated macrophages and indirectly by inhibiting production of inflammatory mediators, the cytokines and chemokines. It inhibits also the MDR-1 gene, which is responsible for the resistance of cancer cells to chemotherapeutic agents and strikes tumor angiogenesis.

  4. Assessment of acculturation in minority health research.

    Fox, Molly; Thayer, Zaneta; Wadhwa, Pathik D

    2017-03-01

    Acculturation represents an important construct in the context of health disparities. Although several studies have reported relationships between various aspects of acculturation and health in minority populations, crucial inconsistencies remain. One likely reason for these inconsistencies may relate to limitations in the conceptualization and operationalization of acculturation, particularly in the context of health research. The acculturation construct underwent major conceptual and operational change when it was adapted from anthropology to psychology, and we argue another major shift is now required for use of this construct in health research. Issues include determining whether acculturation measures should focus on an individual's internal attitudes or overt behaviors; whether they should characterize cultural orientation status at a given point in time or change over time; whether measures should be culture-specific or more global in nature; how the issue of multiculturalism should be addressed; how measures can optimally incorporate multiple dimensions of acculturation; and whether proxy measures should be used. These issues are important in the context of health research because of their implications for determining the direct and indirect effects of cultural change on health-related biological and behavioral processes. We elaborate on and address each of these issues from a perspective that spans multiple disciplines across the biological and social sciences, and offer concrete recommendations with the ultimate goal of achieving a better understanding of the role of acculturation in minority health and health disparities.

    2010-01-01

    This article summarizes data from a qualitative study investigating the ways in which female youth perceive and respond to challenges related to the interplay of late adolescence and a minority sexual orientation. Fifteen sexual minority females in late adolescence were interviewed individually and in focus groups. The interviews focused on participants' perceptions of challenges, the impact those stressors have in their lives, and methods they utilize to cope with them. The most common negative experiences reported were isolation, lack of acceptance, harassment, and violence. Sub-themes include: hearing negative messages about gender and sexual orientation, pressures to conform to a variety of cultural norms including gender norms, fears of future violence, and pressure to identify sexual orientation. Collectively, the participants described these negative consequences of experiences of heterosexism, sexism, and racism as their most difficult experiences. The most common responses to these stressors reported by participants were finding support in relationships, engaging in coping responses, pursuing education and activism, rebellion and resistance, and avoidance and deferment.

  7. Minority games, evolving capitals and replicator dynamics

    International Nuclear Information System (INIS)

    Galla, Tobias; Zhang, Yi-Cheng

    2009-01-01

    We discuss a simple version of the minority game (MG) in which agents hold only one strategy each, but in which their capitals evolve dynamically according to their success and in which the total trading volume varies in time accordingly. This feature is known to be crucial for MGs to reproduce stylized facts of real market data. The stationary states and phase diagram of the model can be computed, and we show that the ergodicity breaking phase transition common for MGs, and marked by a divergence of the integrated response, is present also in this simplified model. An analogous majority game turns out to be relatively void of interesting features, and the total capital is found to diverge in time. Introducing a restraining force leads to a model akin to the replicator dynamics of evolutionary game theory, and we demonstrate that here a different type of phase transition is observed. Finally we briefly discuss the relation of this model with one strategy per player to more sophisticated minority games with dynamical capitals and several trading strategies per agent

    Charity, Pamela C.; Klein, Paul B.; Wadhwa, Bhushan

    1995-01-01

    The Cleveland State University Minority Engineering Program Pipeline consist of programs which foster engineering career awareness, academic enrichment, and professional development for historically underrepresented minority studies. The programs involved are the Access to Careers in Engineering (ACE) Program for high school pre-engineering students: the LINK Program for undergraduate students pursuing degree which include engineering; and the PEP (Pre-calculus Enrichment Program) and EPIC (Enrichment Program in Calculus) mathematics programs for undergraduate academic enrichment. The pipeline is such that high school graduates from the ACE Program who enroll at Cleveland State University in pursuit of engineering degrees are admitted to the LINK Program for undergraduate level support. LINK Program students are among the minority participants who receive mathematics enrichment through the PEP and EPIC Programs for successful completion of their engineering required math courses. THese programs are interdependent and share the goal of preparing minority students for engineering careers by enabling them to achieve academically and obtain college degree and career related experience.

    2013-10-01

    In line of the development of a food composition database for Bangladesh, 10 minor indigenous fruits were analysed for their nutrient composition comprising ascorbic acid, carotenoids and mineral values. Nutrient data obtained have been compared with published data reported in different literatures, book and United States Department of Agriculture-National Nutrient Database for Standard Reference. Ascorbic acid was highest in Wood apple and lowest in Roselle. Monkey jack contained the highest amount of carotenoids, zinc and copper. Content of calcium, magnesium and phosphorous were found highest in Antidesma velutinum. Potassium was the highest in Wood apple followed by in Moneky jack. It was noted that most of the minor fruits have much higher amount of ascorbic acid than the national fruit - Jack fruit ripe, the king fruit - Mango ripe of Bangladesh and exotic fruits - Apple and Grapes. The nutrient values of these minor fruits would make awareness among the people for their mass consumption for healthy life and to grow more minor fruit trees from extinction in order to maintain biodiversity.

    2001-12-01

    Since 1971, the American Geological Institute (AGI) Minority Participation Program (MPP) has supported scholarships for underrepresented minorities in the geosciences at the undergraduate and graduate levels. Some of our MPP scholars have gone on to hugely successful careers in the geosciences. MPP scholars include corporate leaders, university professors, a NASA scientist-astronaut and a National Science Foundation (NSF) CAREER awardee. Yet as ethnic minorities continue to be underrepresented in the geosciences, AGI plans to expand its efforts beyond its traditional undergraduate and graduate scholarships to include diversity programs for secondary school geoscience teacher internships, undergraduate research travel support, and doctoral research fellowships. Funding for the MPP has come from multiple sources, including industry, scientific societies, individuals, and during the last 10 years, the NSF. College-level students apply for the MPP awards or award renewals, and the MPP Advisory Committee selects scholarship recipients based upon student academic performance, financial need, and potential for success as a geoscience professional. Mentoring is a long-standing hallmark of the AGI MPP. Every AGI MPP scholar is assigned a professional geoscientist as a mentor. The mentor is responsible for regular personal contacts with MPP scholars. The MPP Advisory Committee aims to match the profession of the mentor with the scholar's academic interest. Throughout the year, mentors and scholars communicate about possible opportunities in the geosciences such as internships, participation in symposia, professional society meetings, and job openings. Mentors have also been active in helping younger students cope with the major changes involved in relocating to a new region of the country or a new college culture. We believe that AGI is well-positioned to advance diversity in the geosciences through its unique standing as the major professional organization in the

  4. Management of minor salivary gland carcinomas

    Parsons, James T.; Mendenhall, William M.; Stringer, Scott P.; Cassisi, Nicholas J.; Million, Rodney R.

    1996-01-01

    Purpose: To assess the role of radiotherapy alone or in combination with surgery in the treatment of patients with malignant minor salivary gland carcinomas. Methods and Materials: Between October 1964 and November 1992, 95 patients with minor salivary gland carcinomas of the head and neck received radiotherapy with curative intent. Eighty-seven patients were previously untreated, and 8 were treated for postsurgical recurrence. Fifty-one patients were treated with radiotherapy alone, and 44 were treated by surgical resection plus radiotherapy. Patients were staged according to the 1983 American Joint Committee on Cancer (AJCC) staging criteria for squamous cell carcinomas. Results: The 20-year actuarial rate of local control was 57% with no significant difference according to histologic type. When tumor stage was taken into consideration, there were no significant differences in local control according to tumor site. The 12-year actuarial probability of distant metastases was 40% (19% as the only site of failure). In multivariate analyses, local control was significantly affected only by tumor stage and treatment type (combined therapy better than radiotherapy alone); tumor stage was a significant predictor of cause-specific survival and freedom from relapse. Freedom-from-relapse rates were higher for patients who received combined treatment (p = 0.068). Conclusions: Treatment of minor salivary gland carcinomas is usually by combined surgery and radiotherapy, but there are situations where surgery alone or radiotherapy alone may be used. The ability to control these tumors with radiotherapy alone is not widely recognized. In the present series, the tumor was locally controlled in 20 patients with previously untreated primary lesions after radiotherapy alone (2.5 to 21 years) and in 4 other patients who were treated by radiotherapy alone for postsurgical recurrent tumor (3.5 to 14 years after radiotherapy). Contrary to the widely held belief that local recurrence

    Black sexual minority women are triply marginalized due to their race, gender, and sexual orientation. We compared three dimensions of discrimination—frequency (regularity of occurrences), scope (number of types of discriminatory acts experienced), and number of bases (number of social statuses to which discrimination was attributed)—and self-reported mental health (depressive symptoms, psychological well-being, and social well-being) between 64 Black sexual minority women and each of two groups sharing two of three marginalized statuses: (a) 67 White sexual minority women and (b) 67 Black sexual minority men. Black sexual minority women reported greater discrimination frequency, scope, and number of bases and poorer psychological and social well-being than White sexual minority women and more discrimination bases, a higher level of depressive symptoms, and poorer social well-being than Black sexual minority men. We then tested and contrasted dimensions of discrimination as mediators between social status (race or gender) and mental health outcomes. Discrimination frequency and scope mediated the association between race and mental health, with a stronger effect via frequency among sexual minority women. Number of discrimination bases mediated the association between gender and mental health among Black sexual minorities. Future research and clinical practice would benefit from considering Black sexual minority women's mental health in a multidimensional minority stress context. PMID:26424904

    We study a cost function for the aggregate behavior of all the agents involved in the minority game (MG) or the bar attendance model (BAM). The cost function allows us to define a deterministic, synchronous dynamic that yields results that have the main relevant features than those of the probabilistic, sequential dynamics used for the MG or the BAM. We define a temperature through a Langevin approach in terms of the fluctuations of the average attendance. We prove that the cost function is an extensive quantity that can play the role of an internal energy of the many-agent system while the temperature so defined is an intensive parameter. We compare the results of the thermal perturbation to the deterministic dynamics and prove that they agree with those obtained with the MG or BAM in the limit of very low temperature.

  13. Towards the Enhancement of "MINOR" Archaeological Heritage

    Morandi, S.; Tremari, M.; Mandelli, A.

    2017-02-01

    The research is an analysis of the recording, reconstruction and visualisation of the 3D data of a XVIII century watermill, identified in an emergency archaeological excavation during the construction of the mini-hydroelectric plant on the bank of the Adda river in the municipality of Pizzighettone (Cremona, Lombardy, Italy). The work examines the use and the potentials of modern digital 3D modelling techniques applied to archaeological heritage aimed to increase the research, maintenance and presentation with interactive products. The use of three-dimensional models managed through AR (Augmented Reality) and VR (Virtual Reality) technologies with mobile devices gives several opportunities in the field of study and communication. It also improves on-site exploration of the landscape, enhancing the "minor" archaeological sites, daily subjected to numerous emergency works and facilitating the understanding of heritage sites.

  14. Dynamics of a spherical minority game

    International Nuclear Information System (INIS)

    Galla, T; Coolen, A C C; Sherrington, D

    2003-01-01

    We present an exact dynamical solution of a spherical version of the batch minority game (MG) with random external information. The control parameters in this model are the ratio of the number of possible values for the public information over the number of agents, and the radius of the spherical constraint on the microscopic degrees of freedom. We find a phase diagram with three phases: two without anomalous response (an oscillating versus a frozen state) and a further frozen phase with divergent integrated response. In contrast to standard MG versions, we can also calculate the volatility exactly. Our study reveals similarities between the spherical and the conventional MG, but also intriguing differences. Numerical simulations confirm our analytical results

    Many dynamical systems produce large quantities of data. How can the system be understood from the output data? Often people are simply overwhelmed by the data. Traditional tools such as tables and plots are often not adequate, and new techniques are needed to help people to analyze the system. In this paper, we propose the use of two spacefilling visualization tools to examine the output from a complex agent-based financial model. We measure the effectiveness and performance of these tools through usability experiments. Based on the experimental results, we develop two new visualization techniques that combine the advantages and discard the disadvantages of the information visualization tools. The model we use is an evolutionary version of the Minority Game which simulates a financial market.

    Science.gov (United States)

    Burgos, E.; Ceva, Horacio; Perazzo, R. P. J.

    2001-05-01

    We study the bar attendance model (BAM) and a generalized version of the minority game (MG) in which a number of agents self organize to match an attendance that is fixed externally as a control parameter. We compare the probabilistic dynamics used in the MG with one that we introduce for the BAM that makes better use of the same available information. The relaxation dynamics of the MG leads the system to long lived, metastable (quenched) configurations in which adaptive evolution stops in spite of being far from equilibrium. On the contrary, the BAM relaxation dynamics avoids the MG glassy state, leading to an equilibrium configuration. Finally, we introduce in the MG model the concept of annealing by defining a new procedure with which one can gradually overcome the metastable MG states, bringing the system to an equilibrium that coincides with the one obtained with the BAM.

    Galla, Tobias; De Martino, Andrea

    2008-01-01

    The existence of a phase transition with diverging susceptibility in batch minority games (MGs) is the mark of informationally efficient regimes and is linked to the specifics of the agents' learning rules. Here, we study how the standard scenario is affected in a mixed population game in which agents with the 'optimal' learning rule (i.e. the one leading to efficiency) coexist with those whose adaptive dynamics is sub-optimal. Our generic finding is that any non-vanishing intensive fraction of optimal agents guarantees the existence of an efficient phase. Specifically, we calculate the dependence of the critical point on the fraction q of 'optimal' agents focusing our analysis on three cases: MGs with market impact correction, grand-canonical MGs and MGs with heterogeneous comfort levels

  19. The Hamming distance in the minority game

    Science.gov (United States)

    D'hulst, R.; Rodgers, G. J.

    1999-08-01

    We investigate different versions of the minority game, a toy model for agents buying and selling a commodity. The Hamming distance between the strategies used by agents to make decisions is introduced as an analytical tool to determine several properties of these models. The success rate of the agents in an adaptive version of the game is compared with the rate from a stochastic version. It is shown numerically and analytically that the adaptive process is inefficient, increasing the success rate of the unused strategies while decreasing the success rate of the strategies used by the agents. The agents do not do as well as if they were forced to use only one strategy permanently. A version of the game in which the agents strategies evolve is also analysed using the notion of distance. The agents evolve into a state in which they are all using one strategy, which is again the state that yields the maximum success rate.

  20. Own education institutions as an option for minority groups

    1998-03-01

    Full Text Available In this article the introductory part deals with Christian guidelines regarding the rights of minority groups. In the ensuing part the provision of education according to the unique educational needs of minority groups is discussed within the context of the presented guidelines. It is indicated that own education is internationally accepted as one of the major rights of minority groups. Within the international context, for example in the treaties of Unesco and in the educational provision of several countries, it is accepted that minority groups also prefer their own education institutions in order to effectively provide in their unique educational needs. In this article the more general requirements, regarding the characteristics of the education institution needed to meet the unique educational needs of a particular minority group are also identified. The impending problems in South Africa regarding own education schools for minorities are discussed briefly. In order to find possible solutions the situation in the Netherlands regarding "bijzondere scholen” to provide in the unique educational needs of particular interest groups and particularly religious groups is analysed. The conclusion arrived at is that the mentioned situation does not oppose Christian guidelines if minorities need each other to influence educational change, that the acknowledgement of the educational rights of minority groups promotes national unity, that the educational rights of minorities should imply freedom of establishment, denomination and institution and that the educational rights of minorities are fully realised if their education is financially supported by government on an equal basis to that of the majority.

    Highlights: • Key issues associated with MA transmutation are the appropriate loading pattern. • Commercial PWRs are the only choice to transmute MAs in large scale currently. • Considerable amount of MA can be loaded to PWR without disturbing k eff markedly. • Loading MA to PWR burnable poison rods for transmutation is an optimal loading pattern. - Abstract: Minor actinides are the primary contributors to long term radiotoxicity in spent fuel. The majority of commercial reactors in operation in the world are PWRs, so to study the minor actinide transmutation characteristics in the PWRs and ultimately realize the successful minor actinide transmutation in PWRs are crucial problem in the area of the nuclear waste disposal. The key issues associated with the minor actinide transmutation are the appropriate loading patterns when introducing minor actinides to the PWR core. We study two different minor actinide transmutation materials loading patterns on the PWR burnable poison rods, one is to coat a thin layer of minor actinide in the water gap between the zircaloy cladding and the stainless steel which is filled with water, another one is that minor actinides substitute for burnable poison directly within burnable poison rods. Simulation calculation indicates that the two loading patterns can load approximately equivalent to 5–6 PWR annual minor actinide yields without disturbing the PWR k eff markedly. The PWR k eff can return criticality again by slightly reducing the boric acid concentration in the coolant of PWR or removing some burnable poison rods without coating the minor actinide transmutation materials from PWR core. In other words, loading minor actinide transmutation material to PWR does not consume extra neutron, minor actinide just consumes the neutrons which absorbed by the removed control poisons. Both minor actinide loading patterns are technically feasible; most importantly do not need to modify the configuration of the PWR core and

  10. A Climate Change Minor that gets Physics Students talking to Philosophy Students

    We started a Climate Change Studies Minor at the University of Montana in 2008. The curriculum is divided into three Sections: Science, Society and Solutions. Faculty from at least 8 different departments offer courses. The Science curriculum is what you would expect, however we worked hard to build the Society Section to include courses in political science, ethics, economics, communication, international policy. The Solutions Section introduces a variety of sustainability, renewable energy and green business courses, and internships and practicums with local organizations and businesses. Our goal has been a Minor that can be taken by students from any major on campus. The high point for me is watching the AGU type geeks interacting with philosophy majors, business students, and pre-law students.

    Full Text Available Full medical evaluation is paramount for all trauma patients. Minor traumas are often overlooked, as they are thought to bear low injury potential. In this case report, we describe the case of a 48-year-old man presenting to our Emergency Department with mild to moderate right-sided shoulder and scapular pain following a fall from his own height ten days previously. Clinical and paraclinical investigations (CT revealed diffuse right shoulder pain, with crepitations on palpation of the neck, right shoulder, and right lateral chest wall. Computed tomography (CT demonstrated right-sided costal fractures (ribs 7 to 9, with diffuse subcutaneous emphysema and pneumomediastinum due to laceration of the visceral and parietal pleura and the adjacent lung parenchyma. In addition, a small ipsilateral pneumothorax was found. Surprisingly, the clinical status was only minimally affected by mild to moderate pain and minor functional impairment.

  12. Departments as Agents of Change

    Higher education is changing because it has no choice. And, for the most part, outside influences are dictating the processes of change. The more fortunate institutions have had a flat budget during this period, but most have been forced to deal with a declining revenue stream as well. Legislators seem bent on micromanaging state-supported institutions, even as they cut their support. Regulators demand greater institutional accountability. Students and their parents expect more service at lower prices and increased flexibility. Technological advances have dramatically affected the availability and accessibility of extant knowledge. It is no longer a question of whether institutions will change, but rather, who will control the change. Most institutions possess long-standing academic traditions, but these are placed at risk in an increasingly competitive market that holds little sympathy for such traditions and may even see them as obstacles or barriers. As a result, the change agents will undoubtedly have a profound effect on the very nature of academic institutions. From the academic point of view, it would seem prudent to attempt to manage the changes that will inevitably occur. A number of concerned observers, notably the Pew Higher Education Roundtable and the American Association for Higher Education, argue persuasively that the academic department is the logical focus for responding to the current winds of change. Using a marketing metaphor, the academic department has been likened to a "producers' cooperative" of services that consumers seek. Thus, the department should be held accountable for the quality of teaching delivered by its members, for the coherence of its major, for its contributions to the general education curriculum, and for supervising and rewarding its individual faculty members. If departments are to be held accountable, it is surely in their best interest to act in such a way that they are accountable. Expecting academic departments to be

  13. NATIONAL MINORITIES IN THE LAW OF THE EC/EU

    Full Text Available In the law of the EC/EU the protection of national minorities is still a marginal matter. The EU has relied on general international law and on a European regional system of international law and, in case of necessity, accepted their norms. But in the 1990s there began a process of “de-economisation of the European integration” and the importance of national minorities became higher. Protection of the national minorities has not become a generally accepted legally binding principle of the EU, although in several legal acts issues of national minorities are mentioned. On the other hand, the political relevance of national minorities´ protection is very high. The importance of protection of national minorities in future will probably grow. It is a result of the adoption of the Charter of Fundamental Rights of the EU (2000 and of the discussions regarding the European constitution and the Treaty of Lisbon.

  14. Low velocity encounters of minor bodies with the outer planets

    Previous studies of close encounters of minor bodies with Jupiter have shown that the perturbations are stronger either if the encounter is very deep or if the velocity of the minor body relative to the planet is low. In the present research the author investigates the effects of low velocity encounters between fictitious minor bodies and the four outer planets. Two possible outcomes of this type of encounter are the temporary satellite capture of the minor body by the planet, and the exchange of perihelion with aphelion of the minor body orbit. Different occurrence rates of these processes are found for different planets, and the implications for the orbital evolution of minor bodies in the outer Solar System are discussed. (Auth.)

RESULTS: Individuals with a high number of minor physical anomalies developed schizophrenia spectrum disorders significantly more often than they developed a no mental illness outcome. Further, individuals with a high number of minor physical anomalies tended to develop schizophrenia......OBJECTIVE: The authors prospectively assessed the relationship between minor physical anomalies identified in childhood and adult psychiatric outcome. METHOD: In 1972, minor physical anomalies were measured in a group of 265 Danish children ages 11-13. The examination was part of a larger study...... spectrum disorders more often than other psychopathology. Among individuals at genetic high risk, higher numbers of minor physical anomalies may interact with pre-existing vulnerabilities for schizophrenia to increase the likelihood of a schizophrenia spectrum disorder outcome. CONCLUSIONS: Minor physical...

    It is well documented that, in the presence of substantial fixed costs, markets offer preference majorities more variety than preference minorities. This fact alone, however, does not demonstrate the market outcome is in any way biased against preference minorities. In this paper, we clarify the sense in which the market outcome may in fact be biased against preference minorities, and we provide some conditions for such bias to occur. We then estimate the degree of bias in a particular indust...

    This chapter offers an analysis of majority vs. minority influence using the Heuristic-Systematic Model of persuasion (HSM). We evaluate evidence for and against leading perspectives such as Conversion Theory. Next, research and theory is reviewed suggesting that majority vs. minority influence differentially affect the processing of persuasive arguments. A dual-role interpretation of majority and minority influence is presented. First, numerical support for discrepant messages affects the de...
