    West, F.G.; Laughlin, A.W.

    1979-05-01

    Exploration for Hot Dry Rock (HDR) requires the ability to delineate areas of thermal enhancement. It is likely that some of these areas will exhibit various sorts of anomalous conditions such as seismic transmission delays, low seismic velocities, high attenuation of seismic waves, high electrical conductivity in the crust, and a relatively shallow depth to Curie point of Magnetization. The Aquarius Mountain area of northwest Arizona exhibits all of these anomalies. The area is also a regional Bouguer gravity low, which may indicate the presence of high silica type rocks that often have high rates of radioactive heat generation. The one deficiency of the area as a HDR prospect is the lack of a thermal insulating blanket.

    The results of a preliminary environmental assessment of the following geopressured-geothermal prospect areas in the Louisiana Gulf coast region are presented: South Johnson's Bayou, Sweet Lake, Rockefeller Refuge, Southeast Pecan Island, Atchafalaya Bay, and Lafourche Crossing. These prospect areas have been compared to determine their relative environmental acceptability for the test program. Trade-offs among the prospects in terms of potential impacts are highlighted. This assessment was made on the basis of the nature and extent of the proposed testing activities in view of the environmental characteristics of each prospect area: land use, geology and geohydrology, air quality, water resources and quality, ecological systems, and natural hazards. The comparison of prospect areas includes consideration of worst case situations. However, we believe that the test program activities, because they are so small in scale, will not result in major adverse impacts.

    The climatic factors in the coastal areas are cogent in planning a stable and functional solar farm. The experiment performed in this study entails a day-to-day solar radiation pattern in coastal areas. The results show that the solar radiation pattern in coastal region portends danger to the performance of solar photovoltaic (PV) module and its lifecycle. The efficiency of the PV module was tested in the harmattan where dust is a major hindrance. The results were related to meteorological parameters which influences the solar radiation over an area. The solar radiation pattern in coastal areas was traced to the solar sectional shading theory which was summarized and explained.

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

  11. Prospects for Pulsar Studies with the GLAST Large Area Telescope

    Harding, Alice K.

    2007-01-01

    The Large Area Telescope (LAT) on the Gamma-ray Large Area Space Telescope (GLAST), due to launch in November 2007, will have unprecedented sensitivity and energy resolution for gamma-rays in the range of 30 MeV to 200 GeV. GLAST is therefore expected to provide major advances in the understanding of high-energy emission from rotation-powered pulsars. As the only presently known galactic GeV source class; pulsars will be one of the most important sources for study with GLAST. The main science goals of the LAT for pulsar studies include an increase in the number of detected radio-loud and radio-quiet gamma-ray pulsars, including millisecond pulsars, giving much better statistics for elucidating population characteristics, measurement of the high-energy spectrum and the shape of spectral cutoffs and determining pulse profiles for a variety of pulsars of different age. Further, measurement of phase-resolved spectra and energy dependent pulse profiles of the brighter pulsars should allow detailed tests of magnetospheric particle acceleration and radiation mechanisms, by comparing data with theoretical models that have been developed. Additionally, the LAT will have the sensitivity to allow blind pulsation searches of nearly all unidentified EGRET sources, to possibly uncover more radio-quiet Geminga-like pulsars.

    2013-08-01

    Full Text Available The costs of geothermal exploration are very high because technology is still imported from other countries. The local business players in the geothermal sector do not have the ability to compete with global companies. To reduce costs, we need to develop our own equipment with competitive prices. Here in Indonesia, we have started to design a prototype of temperature logging tools for geothermal prospecting areas. This equipment can be used to detect temperature versus depth variations. To measure the thermal gradient, the platinum resistor temperature sensor is moved slowly down along the borehole. The displacement along the borehole is measured by a rotary encoder. This system is controlled by a 16-bit H8/3069F microcontroller. The acquired temperature data is displayed on a PC monitor using a Python Graphical User Interface. The system has been already tested in the Gunung Pancar geothermal prospect area in Bogor.

  16. The Best Combination Methods and Applied Research of Seismic Prospecting for Active Faults in Urban Areas

    2007-01-01

    This paper introduces briefly the basic principles of various seismic prospecting techniques and working methods according to nationwide practices of seismic prospecting of active faults beneath big cities in recent years. Furthermore, it analyzes the application range of different seismic prospecting methods, main achievements and solved problems, and discusses the best combination of seismic exploration methods for detecting crustal structures and locating the faults used in the present stage, that is, to trace faults which are at depths of hundred of meters underground using shallow seismic investigation, to detect the faults which are above basement (at a depth of kilometers) using high resolution refraction sounding, and the deep crustal faults using combined seismic prospecting methods of reflection seismic sounding and wide-angle reflection/refraction sounding, and furthermore, to use the 3-D deep seismic sounding method to obtain 3-D velocity structures beneath urban areas. Thus, we can get information about fault attitude and distribution at different depths and a complete image of faults from their shallow part to deep part using the combined seismic exploration method. Some application examples are presented in the article.

    Prospecting for suitable areas for forestry operations, where the objective is a reduction in production and transportation costs, as well as the maximization of profits and available resources, constitutes an optimization problem. However, fuzzy logic is an alternative method for solving this problem. In the context of prospecting for suitable areas for the installation of wood panel industries, we propose applying fuzzy logic analysis for simulating the planting of different species and eucalyptus hybrids in Espírito Santo State, Brazil. The necessary methodological steps for this study are as follows: a) agriclimatological zoning of different species and eucalyptus hybrids; b) the selection of the vector variables; c) the application of the Euclidean distance to the vector variables; d) the application of fuzzy logic to matrix variables of the Euclidean distance; and e) the application of overlap fuzzy logic to locate areas for installation of wood panel industries. Among all the species and hybrids, Corymbia citriodora showed the highest percentage values for the combined very good and good classes, with 8.60%, followed by Eucalyptus grandis with 8.52%, Eucalyptus urophylla with 8.35% and Urograndis with 8.34%. The fuzzy logic analysis afforded flexibility in prospecting for suitable areas for the installation of wood panel industries in the Espírito Santo State can bring great economic and social benefits to the local population with the generation of jobs, income, tax revenues and GDP increase for the State and municipalities involved. The proposed methodology can be adapted to other areas and agricultural crops. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Full Text Available Language is one of the medium of expressing our ideas, feelings and emotions. And if we think about language in present world then English is one of the most used languages in the world and English is used as a second language in Bangladesh. English is introduced here at the primary level and its inclusion continues till the tertiary level of education. Most of the students of the primary schools in rural areas are weak in English language due to lack of skilled and trained teachers who are familiar to the modern methods and approaches of teaching and lack of materials for teaching in the classroom. Primary level English curriculum implementation is essential in Bangladesh to achieve the set English language competency in the rural areas. Students in the rural areas are performing poorly in English compared to their urban counterparts. Statistics showed that there was a gulf of difference between the facilities enjoyed by rural schools and urban schools. The study explores the challenges of teaching English language in rural areas in context of Bangladesh. This study investigated the factors affecting student’s performance in English language in rural areas. Data were collected using interviews, classroom observation and questionnaire. Result of the study reveals that students were highly motivated to learn English for future expectations such as local and international communication, academic advancement and employment prospects. It also provide a scenario of English teaching system in rural areas of Bangladesh as well as the problems and prospects of English language in perspective of Bangladesh.

  3. Developing satellite communications for public service: Prospects in four service areas

    Science.gov (United States)

    1977-01-01

    The Public Service Satellite Consortium evaluated prospects for satellite telecommunications in four areas of the public service: the U.S. health care system, elementary and secondary education, American libraries, and that sector of the public service which is concerned with the provision of continuing education to health professionals. Three important conclusions were reached. First, throughout the public service there are three recurring needs: improved access, cost containment, and maintenance of quality. Appropriate application of communication satellite systems could ameliorate each of these concerns. Second, there appears to be an enormous latent demand for data communication services throughout the public service. The potential demand in 1982 to support requirements in hospital administration, library services and other information-retrieval activities, equipment maintenance, and environmental monitoring may be in excess of $300 million a year. Third, administrative applications of data communication networks show particular promise, especially in rural areas.

  4. Identifying Potential Area and Financial Prospects of Rooftop Solar Photovoltaics (PV

    Sarawut Ninsawat

    2016-10-01

    Full Text Available In an urban area, the roof is the only available surface that can be utilized for installing solar photovoltaics (PV, and the active surface area depends on the type of roof. Shadows on a solar panel can be caused by nearby tall buildings, construction materials such as water tanks, or the roof configuration itself. The azimuth angle of the sun varies, based on the season and the time of day. Therefore, the simulation of shadow for one or two days or using the rule of thumb may not be sufficient to evaluate shadow effects on solar panels throughout the year. In this paper, a methodology for estimating the solar potential of solar PV on rooftops is presented, which is particularly applicable to urban areas. The objective of this method is to assess how roof type and shadow play a role in potentiality and financial benefit. The method starts with roof type extraction from high-resolution satellite imagery, using Object Base Image Analysis (OBIA, the generation of a 3D structure from height data and roof type, the simulation of shadow throughout the year, and the identification of potential and financial prospects. Based on the results obtained, the system seems to be adequate for calculating the financial benefits of solar PV to a very fine scale. The payback period varied from 7–13 years depending on the roof type, direction, and shadow impact. Based on the potentiality, a homeowner can make a profit of up to 200%. This method could help homeowners to identify potential roof area and economic interest.

    Institute of Scientific and Technical Information of China (English)

    2000-01-01

    The tectonic development of the Tarim block has experienced four stages, i. e. Earth's core accretion and block formation in the Precambrian, margin splitting, opening-closing and piecing up in the Early Palaeozoic, rift formation and plate unification in the Late Palaeozoic, and basin-mountain coupling and landform shaping in the Meso-Cenozoic, forming six ore-bearing formations and ore deposits of various genetic types in the Tianshan Mountains, Kunlun Mountains and Altun Mountains. In the peripheral areas of Tarim there are four giant intercontinental metallogenic belts passing through, the Central Tianshan and southwestern Tianshan belts in the former USSR and the Qinling-Qilian-Kunlun and Palaeo-Tethys belts in China. According to the macro-analysis on the nearly one thousand known deposits (occurrences) and geophysical-geochemical anomalies, and the information from reconnaissance in some areas, the region has very good prospects for mineral resources. Some of the metallogenic belts may well become the reserve bases for exploration of mineral resources in China.

    2012-04-01

    Full Text Available The Kuh Shah prospecting area is located in Tertiary volcano-plutonic belt of the Lut Block. More than seventeen subvolcanic intermediate to acidic intrusive rocks, diorite to syenite in composition, were identified in the study area. The intrusions are related to hydrothermal alteration zones and contain argillic, propylitic, advanced argillic, silicified, quartz-sericite-pyrite, gossan and hydrothermal breccia which overprinted to each other and are accompanied by weathering which made it complicated to distinguish zoning. Mineralization is observed as sulfide (pyrite and rare chalcopyrite, disseminated Fe-oxides and quartz-Fe-oxide stockwork veinlets. Intrusive rocks are metaluminous, calc-alkaline with shoshonitic affinity with high values of magnetic susceptibility. The Kuh Shah intrusive rocks are classified as magnetite-series of oxidant I-type granitoids. Based on zircon U–Pb age dating, the age of these granitoid rocks is 39.7± 0.7 Ma (Middle Eocene. The radioisotope data (initial 87Sr/86Sr and 143Nd/144Nd ratios as well as εNd and geochemical data suggest that the Kuh Shah granitoid rocks formed from depleted mantle in a subduction-related magmatic arc setting. Geochemical anomalies of elements such as Cu, Au, Fe, Pb, Zn, As, Sb, Mo, Bi, Hg and also Mn, Ba, Te and Se, correlated with quartz-sericite-pyrite, gossan-stockwork-hydrothermal breccias, irregular silicified bodies and advanced argillic hydrothermal alteration zones. Geophysical anomalies correlated with hydrothermal alteration and mineralization zones. The interpretation of the results represents complex patterns of sub-circular to ellipsoid shape with north-east to south-west direction. These evidences are similar to the other for known Cu-Au porphyry and Au-epithermal systems in Iran and worldwide.

    Full Text Available The Halak Abad prospect occurs in the northeastern part of Central Iran zone (Sabzevar structural zone. In this investigation, geochemical evolution, age and source of part of northeastern Iran magmatic arc (intrusive bodies in Halak Abad area in the Khorasan Razavi province has been studied. The exposed rocks consist of volcanic rocks with andesite and dacite nature, limestone, plutonic rocks mostly diorite, quartz diorite, monzodiorite, quartz monzonite, granodiorite and granite and sedimentary rocks such as limestone, sandstone and conglomerate. Magnetic susceptibility of intrusive rocks is >100 × 10-5 SI, so they belong to the magnetite-series (oxidized. This magmatism is mainly low-K (tholeiite series and meta-aluminous. The amounts of Zr, Th, Nb and Ti show depletion compared to N-MORB. Trace elements behavior shows a nearly flat pattern. Age of granodiorite body based on U-Pb zircon dating is 99.7±1.8 Ma (Mid-Cretaceous and 87Sr/86Sr initial ratio is 0.7047. The geochemical signature and 87Sr/86Sr initial ratio in the area suggest volcanic arc magmatism in subduction zone. This magmatism has characteristic such as high Na2O (3-7 %, low K2O (0.12-1 %, high CaO (4-5.7%, low Rb (1-20 ppm, low total REE (<40 ppm, high Ba/Nb, Sm/Yb<2, (La/YbN<5, 87Sr/86Sr initial ratio < 0.7045 and εNd: +4.5 show differences with normal granitoids in subduction zones. Geochemical and petrological characteristics indicate melting in relatively low pressure (shallow depth. The lines of evidence demonstrate that formation of this granitoid needs a suprasubduction zone.

    To investigate the effect that panretinal photocoagulation to peripheral areas of retinal vascular nonperfusion has on the visual acuity and injection frequency of ranibizumab in eyes with previous central retinal vein occlusion. Patients enrolled in a prospective study of ranibizumab for central retinal vein occlusion were imaged with wide-field angiography using the Optos P200 system. Laser photocoagulation was carried out and the extent of laser photocoagulation was evaluated with repeat wide-field angiography. Injection of ranibizumab was based on an as needed strategy throughout the study. The injection frequency in the 6 months before laser was compared with a 6-month period starting 2 months after the laser photocoagulation. The visual acuity was measured by Early Treatment Diabetic Retinopathy Study protocol refraction at both the end of the 6-month follow-up period and at the time of laser photocoagulation. There were 10 patients treated in this study with a mean number of 1,757 spots of laser photocoagulation in the peripheral retina. The injection frequency in the 6-month lead-in period was 3.4 and in the 6-month follow-up period was 3.1, a difference that was not significant (P = 0.26). The visual acuity at the time of laser photocoagulation was 54.2 letters (approximate Snellen equivalent of 20/80) and at the end of the observation period was 51.4 letters, a difference that was not significant (P = 0.33). In this small study, laser photocoagulation to peripheral areas of nonperfusion as visualized by wide-field angiography did not result in either decreased injection frequency or improved visual acuity in eyes with central retinal vein occlusion treated with ranibizumab.

    Site The roman town "Caesarea", which was named "Sezer" and used as a citadel in middle ages, is located within the modern town "Shayzar" in the north-west of Syria. The modern buildings, power lines and the streets with a lot of cars cause a very noisy environment for geophysical prospection. A football ground of about 50x90 m was chosen for testing both methods, magnetic and ground penetrating radar (GPR), to detect archaeological structures. Instruments and survey area The magnetic survey was carried out using a fluxgate magnetic acquisition system with 4 sensors in gradient array from the manufacturer FÖRSTER® mounted on a one wheel cart. The cart was developed in our institute and allows to record high quality data in areas with difficult field conditions. An optical distance measurement system on the wheel ensures an exact positioning of the magnetic data. The measurement grid was 50x10 cm. GPR survey was carried out using a NOGGIN system with 250 MHz antenna from the manufacturer Sensors & Software. A new base plate was mounted on the antenna for the easy moving at rough surface conditions. The measurement grid was 50x5 cm. Data processing The magnetic data are processed using the self developed software ApMag. The main steps of the processing are filtering, removing of the line pattern, interpolation to a grid of 10x10 cm, geo-referencing and producing of a grey scale magnetogramm for visualizing in a geographical information system (GIS). The GPR data are automatically processed using the self developed software package ApRadar. Several pre-processing steps were carried out including removing of constant shifts, automatic detection of the starting point (time zero), frequency dependent high-pass filtering and a background removal filter to get the best results for each measurement. There is no gain control algorithm applied to the traces of a section but a statistical correction of each depth-slice for each section. This is equal to an automatic gain

    Full Text Available Collaborative governance of protected areas has emerged as a response to failures of, and ethical concerns about, centralised environmental governance. This paper assesses the governance of the Hin Nam No National Protected Area in central Laos to identify the conditions that support successful collaborative governance. Our analysis is based on the argument that collaborative governance is more likely to be successful under conditions that provide incentives for community engagement, formal mechanisms for power sharing, local ownership of resources, downward accountability, mechanisms for building trust, and an adaptive approach to performance assessment and improvement. We show that collaborative governance in Hin Nam No demonstrates the potential for a more decentralised and democratic system of governance based on customary rights, but requires ongoing political will to consolidate and sustain these arrangements. The findings of this study contribute to the growing literature on collaborative governance of protected areas in Asia and elsewhere.

    CandiUmbul is one of the manifestation locations in Telomoyo geothermal prospect area. This manifestation is warm spring which assumed as outflow. A magnetic study had been conducted in a geothermal prospect area in CandiUmbul, Telomoyo, Central Java. Magnetic method is one of the geophysical methods used to geothermal exploration. Magnetic method measures in the Earth's magnetic field. The purpose of this research has to map the susceptibility distribution in the subsurface due to the geothermal system. Proton Precession Magnetometer (PPM) was used to measure the magnetic field. Data processing started from correcting magnetic data with diurnal and IGRF correction, to achieve the total anomaly magnetic field. Then, the total anomaly magnetic field was reduced to pole. For the quantitative interpretation, we used 2D forward modeling. The 2D forward modeling was conducted to produce the magnetic anomaly modeling with using mag2DC for windows. The result of the quantitative interpretation is the horizontal position of the body due to the anomaly which is located close to the CandiUmbul warm spring. This warm spring was controlled by fault which is the weak zone in this area, so the hot water can easily passed from Telomoyo geothermal reservoir. The research is still ongoing to support the conclusion of qualitative interpretation.

    Recent geologic mapping by the U.S. Geological Survey of more than 2,500 square miles of a relatively little-studied part of central Nevada has outlined four areas favorable for the discovery of metallic mineral deposits. In these areas, lower Paleozoic carbonate rocks crop out below the Roberts Mountains thrust, a widespread fault in central and north-central Nevada. These areas have a stratigraphic and structural setting similar to that of the areas where large, open-pit gold deposits have been discovered recently at Carlin and Cortez in north-central Nevada.

    Background Asbestos related diseases include a number of conditions due to inhalation of asbestos fibres at work, at home or in the environment, such as pleural mesothelioma, asbestosis and calcified pleural plaques. Few epidemiological studies have established the incidence of asbestos related diseases in our area. The present proposal is based on a retrospective study externally funded in 2005 that is currently taking place in the same area and largely carried out by the same research team. The aim of the study is to achieve a comprehensive and coordinated detection of all new cases of Asbestos Related Diseases presenting to primary care practitioners. Methods/design This is a multicentre, multidisciplinary and pluri-institutional prospective study. Setting 12 municipalities in the Barcelona province within the catchment area of the health facilities that participate in the study. Sample This is a population based study, of all patients presenting with diseases caused by asbestos in the study area. Measurements A clinical and epidemiological questionnaire will be filled in by the trained researchers after interviewing the patients and examining their clinical reports. Discussion Data on the incidence of the different Asbestos Related Diseases in this area will be obtained and the most plausible exposure source and space-time-patient profile will be described. The study will also improve the standardization of patient management, the coordination between health care institutions and the development of preventive activities related with asbestos exposure and disease.

    The present distribution of Palaeozoic sediments in the Bornholm area is a consequence of several different tectonic regimes during the Phanerozoic eon. The three main evolutionary phases are: A Caledonian to Variscian phase (with 3 sub-phases) encompassing the Lower Palaeozoic sediments. The sediments are assumed originally to have showed a gradual thickness increase towards the Caledonian Deformation Front located to the south. A syn-rift phase characterized by sedimentation in graben areas and expanding basins commencing in the Rotliegendes and continuing through the Triassic, Jurassic and Lower Cretaceous. This phase was probably initiated by a Late Carboniferous-Early Permian tensional dominated right-lateral wrench fault system within the Sorgenfrei-Tornquest zone. A Post-rift development phase dominated by Late Cretaceous carbonate sedimentation. During Late Cretaceous and Early Tertiary times the Bornholm area was strongly affected by inversion tectonism caused by compressional strike-slip movements. This resulted in reverse faulting and uplift and erosion of former basinal areas. The hydrocarbon potential of the area is based on the maturation of organic matter in the Ordovician Upper Alum Shale. Maturity was mainly achieved during the Silurian to Late Palaeozoic time. The Upper Alum Shale is expected to be overmature in the main part of the study area and mature in the Hanoe Bay Basin. This reflects the assumed primary uniform thickness of the Lower Palaeozoic, with a general thinning towards the northeast. (AB) (4 maps, 81 refs.)

    Background: Cutaneous leishmaniasis (CL) usually occurs in areas with hot and dry climate. In India, the desert areas of Rajasthan, Gujarat, and the plains of Northwestern frontier are endemic for this disorder. Aims and Objectives: The present study was aimed to describe clinicoepidemiological profile of the cases of CL from South Rajasthan, which is a nonendemic area of Rajasthan. Materials and Methods: During a period of 4 years (2010–2014), a total of 23 patients with CL were diagnosed. All the suspected cases of CL were interrogated in detail regarding visit to areas where CL is known to occur. This was followed by clinical examination, relevant investigations, and treatment. All except one patient were treated with azole antifungals. In one patient, CO2 laser ablation was done. Results: There were 12 (52.17%) males and 11 (47.83%) females with age ranging from 3 to 72 years. Duration of disease ranged from 7 days to 10 months. Face (15; 65.22%) and extremities (12; 52.17%) were involved in majority of the patients. Common morphologies were noduloulcerative lesions and crusted plaques. Tissue smear for Leishmania donovani bodies was positive in all except one patient. Conclusion: The present report highlights occurrence of CL in nonendemic area. Further epidemiological studies are required for identification of vector and strain of Leishmania involved. PMID:27688441

    The West Kunlun ore-forming belt is located between the northwestern Qinghai-Tibet Plateau and southwestern Tarim Basin. It situated between the Paleo-Asian Tectonic Domain and Tethyan Tectonic Domain. It is an important component of the giant tectonic belt in central China (the Kunlun-Qilian-Qinling Tectonic Belt or the Central Orogenic Belt). Many known ore-forming belts such as the Kunlun-Qilian Qinling ore-forming zone, Sanjiang (or Threeriver) ore-forming zone, Central Asian ore-forming zone, etc. pass through the West Kunlun area. Three ore-forming zones and seven ore-forming subzones were classified, and eighteen mineralization areas were marked. It is indicated that the West Kunlun area is one of the most favorable region for finding out large and superlarge ore deposits.

    2014-12-01

    Full Text Available Preliminary results of GPR field prospection carried out in the area of the prehistoric mining field Borownia (Ćmielów, Ostrowiec Świętokrzyski District are presented. This mining field forms a belt (30-50 m wide and 700 m long, starting from the valley edge of the Kamienna River southeastwards. Southeastern and western parts of the site have preserved the original post-exploitation relief. Geology of the Borownia mining field was examined and acquired radiograms revealed three distinct zones of anomaly concentrations. The central zone (B is clearly a fragment of the prehistoric mining field, confirmed not only by the GPR sounding but also by archeological surveys. The other two zones have not yet been investigated in detail yet but their surface and archaeological examination may determine only whether their underground structures are natural or have been created by humans. Data obtained during the GPR prospection at the Borownia archaeological site confirmed usefulness of 100, 250 and 500 MHz antennas. The relatively large depth range and good resolution are due to favorable geological conditions.

    Full Text Available Abstract Background Timely vaccination is important to induce adequate protective immunity. We measured vaccination timeliness and vaccination coverage in three geographical areas in South Africa. Methods This study used vaccination information from a community-based cluster-randomized trial promoting exclusive breastfeeding in three South African sites (Paarl in the Western Cape Province, and Umlazi and Rietvlei in KwaZulu-Natal between 2006 and 2008. Five interview visits were carried out between birth and up to 2 years of age (median follow-up time 18 months, and 1137 children were included in the analysis. We used Kaplan-Meier time-to-event analysis to describe vaccination coverage and timeliness in line with the Expanded Program on Immunization for the first eight vaccines. This included Bacillus Calmette-Guérin (BCG, four oral polio vaccines and 3 doses of the pentavalent vaccine which protects against diphtheria, pertussis, tetanus, hepatitis B and Haemophilus influenzae type B. Results The proportion receiving all these eight recommended vaccines were 94% in Paarl (95% confidence interval [CI] 91-96, 62% in Rietvlei (95%CI 54-68 and 88% in Umlazi (95%CI 84-91. Slightly fewer children received all vaccines within the recommended time periods. The situation was worst for the last pentavalent- and oral polio vaccines. The hazard ratio for incomplete vaccination was 7.2 (95%CI 4.7-11 for Rietvlei compared to Paarl. Conclusions There were large differences between the different South African sites in terms of vaccination coverage and timeliness, with the poorer areas of Rietvlei performing worse than the better-off areas in Paarl. The vaccination coverage was lower for the vaccines given at an older age. There is a need for continued efforts to improve vaccination coverage and timeliness, in particular in rural areas.

Here, an independent prospective validation of these results was performed using an overlap-fraction (OF) calculation of various FDG-uptake based threshold

  4. Management of water for irrigation agriculture in semi-arid areas: Problems and prospects

    Science.gov (United States)

    Mvungi, A.; Mashauri, D.; Madulu, N. F.

    Most of the Mwanga district is classified as semi-arid with a rainfall range of 300 and 600 mm. Rainfall patterns in the district are unpredictable and are subject to great fluctuations. Like other semi-arid areas, the district is characterized with land degradation, unreliable rainfall, repeated water shortage, periodic famine, overgrazing, dry land cultivation in the marginal areas and heavy competition for limited biomass between farmers and cattle. Vulnerability here is high due to unreliability of weather. The people of Mwanga are dependent on agriculture for their livelihood. However agriculture is difficult in the area due to inadequate rainfall. For a very long time the people have been dependent on irrigation agriculture to ensure food security. Of late the traditional irrigation system is on the decline threatening food security in the area. This paper examines the state and status of the irrigation canal system in Mwanga district with the view of recommending ways in which it can be improved. The study used participatory, survey and in-depth interviews to obtain both quantitative and qualitative data. The major findings are that social, political, environmental and demographic bases that supported the traditional irrigation system have changed drastically. As a corollary to this, the cultural and religious belief systems that supported and guided the traditional canal system management have been replaced by mistrust and corruption in water allocation. In addition the ownership and management system of the water resources that was vested in the initiator clans has changed and now water user groups own the canals/furrows but they do not own the water sources. This has rendered the control of the water sources difficult if not impossible. Currently the system is faced by a number of problems including shortage of water and poor management as demand for water increases and this has led to serious conflicts among and between crop producers and pastoralists

    2017-02-01

    Effect of vibropercussion plastic strengthening on microhardness and depth of strengthening of tread areas of railway welds is experimentally studied. It is found that improvement of hardness of railway welds requires impact treatment of welds with a unit blow energy of 20 J by an indenter with a cylindrical flat end 55 mm in radius. Under the specified energy impact, a surface layer is formed with the microhardness of 5800–6100 MPa and the strengthened thickness of 1.8–2 mm. The implementation of the technology for vibropercussion plastic strengthening of railway welds needs a moble unit with an electromagnetic drive to be designed.

    1980-02-01

    Information collected and analyzed for a preliminary environmental analysis of geopressured geothermal prospect areas in Colorado and DeWitt Counties, Texas is presented. Specific environmental concerns for each geopressured geothermal prospect area are identified and discussed. Approximately 218 km/sup 2/(85 mi/sup 2/) were studied in the vicinity of each prospect area to: (1) conduct an environmental analysis to identify more and less suited areas for geopressured test wells; and (2) provide an environmental data base for future development of geopressured geothermal energy resources. A series of maps and tables are included to illustrate environmental characteristics including: geology, water resources, soils, current land use, vegetation, wildlife, and meteorological characteristics, and additional relevant information on cultural resources, power- and pipelines, and regulatory agencies. A series of transparent overlays at the scale of the original mapping has also been produced for the purposes of identifying and ranking areas of potential conflict between geopressured geothermal development and environmental characteristics. The methodology for ranking suitability of areas within the two prospect areas is discussed in the appendix. (MHR)

  7. Report on dc soundings over a geothermal prospect in the Bruneau-Grand View area, Idaho

    Energy Technology Data Exchange (ETDEWEB)

    Jackson, D.B.

    1974-01-01

    The d-c sounding survey confirms the presence of a large conductive section of sedimentary and volcanic rocks underlying the low-resistivity AMT anomaly defined by Hoover. Within the conductive section, resistivity boundaries between sedimentary rocks of the Idaho Group, the Banbury Basalt, and Idavada Volcanics appear to be entirely obscured, at least where well data are available. True resistivities near these contacts range from about 3 to 5.5 ohm-m, about 3 to 10 times less than would be expected for similar volcanic rock types saturated with fresh water. Because water samples from wells in the Bruneau-Grand View area are relatively fresh, the greatly decreased resistivities are probably related to a combination of thermal waters and alteration within the volcanic rocks and perhaps also within part of the sedimentary section. The d-c soundings trace the low resistivity zone beyond the limits of the AMT survey to the east as far as the town of Hammett, where a zone of 4.4 ohm-m material 640 m thick is present. To the west the conductive section terminates about 5 km east of Oreana, where truncation of the conductive section appears to be related to decreasing lateral porosity. The 1 to 7 ohm-m conductive section can still be recognized beneath the Snake River Plain between Bruneau and Mountain Home, although the top of the conductor is deeper and the thickness is less than at any other sounding location. The presence of a high-resistivity basement suggests that thermal fluids probably emanate from greater depths than this survey can resolve, rise along fault zones, of which there appear to be many, and then spread laterally through lithologic units that have sufficient porosity. Stratigraphic maps are included.

    Full Text Available A coastal zone is the interface between the land and water that influenced by both of them. Coastal dynamic is influenced by many factors from land and sea, such as sedimentation and current. In order to support marine facility, Marine Geological Institute of Indonesia (MGI plan to build a port. The prospective area is behind MGI office at Cirebon. This study use multi temporal remote sensing data in order to observe trend of coastline change around MGI. Based on the interpretation of the data, there are sedimentation around the MGI water and abrasion due to the presence of Kejawanan’s jetty and Kalijaga River. The result also shows that the current in this region is moving from southeast to northwest. The presence of the Kejawanan’s jetty stymies the movement of sediment. The sediment which is normally moving to the north of the jetty is then trapped on the south side of the structure, so that the sediment precipitates in this region and makes it as the active region of sedimentation and accretion. The presence mangrove conduces to support sedimentation speed and accretion at this region, because of his function as the catchment area. Abrasion occurs in the eastern part of MGI office at the Kalijaga river mouth within the bay. The Kalijaga River mouth is predicted to be the primary source of sedimentation in this area. The coastline change caused by sedimentation will be continuing as long as it is supplied by the sediment. The direction of the sedimentation is parallel to the jetty and it forms ellipsoid, with the sedimentation/accretion region is behind MGI office. The abrasion area is found in Kalijaga River mouth and a small area beside Kalijaga River. In order to build a port, we have to consider this sedimentation process. One of the alternatives to build the port is to make a quay pile model which gives way the current to pass through the other side of the port. Another alternative is to build the port as a pond model but

    Background Clinical diagnosis of Buruli ulcer (BU) due to Mycobacterium ulcerans can be challenging. We aimed to specify the differential diagnosis of skin lesions in a BU endemic area. Method We conducted a prospective diagnostic study in Akonolinga, Cameroon. Patients presenting with a skin ulcer suspect of BU were included. M. ulcerans was detected using swabs for Ziehl-Neelsen staining, PCR and culture. Skin punch biopsies were taken and reviewed by two histopathologists. Photographs of the lesions were taken and independently reviewed by two dermatologists. Final diagnosis was based on consensus, combining the results of laboratory tests and expert opinion. Results/ Discussion Between October 2011 and December 2013, 327 patients with ulcerative lesions were included. Median age was 37 years (0 to 87), 65% were males, and 19% HIV-positive. BU was considered the final diagnosis for 27% of the lesions, 85% of which had at least one positive laboratory test. Differential diagnoses were vascular lesions (22%), bacterial infections (21%), post-traumatic (8%), fistulated osteomyelitis (6%), neoplasia (5%), inflammatory lesions (3%), hemopathies and other systemic diseases (2%) and others (2%). The proportion of BU was similar between HIV-positive and HIV-negative patients (27.0% vs. 26.5%; p = 0.940). Half of children below 15 years of age were diagnosed with BU, compared to 26.8% and 13.9% among individuals 15 to 44 years of age and above, respectively (chi2 p<0.001). Children had more superficial bacterial infections (24.3%) and osteomyelitis (11.4%). Conclusion We described differential diagnosis of skin lesions in a BU endemic area, stratifying results by age and HIV-status. PMID:27074157

    This work is focussed on lithologies occurring at Quinta de São Pedro das Águias, which is located in the Tabuaço prospect (an area of 45 km2 where exploration for W-skarn deposits is taking place, in northern Portugal, close to the Douro valley). At Quinta de São Pedro das Águias several lithologies are recognized: "normal" phyllites, black phyllites (graphite-bearing), marbles, calcsilicate (s.s.) rocks and skarns (sometimes, scheelite-bearing), belonging to the Bateiras Formation, of the Douro Group (one of the two major subdivisions of the Neoproterozoic-Cambrian Dúrico-Beirão Supergroup); Paredes da Beira-Tabuaço granite; several aplitic and pegmatitic bodies. The studied area belongs to the Central Iberian Zone, a geotectonic unit of the Iberian Variscan Chain. Rb-Sr isotope analyses done in the scope of this work, provided a 316 ± 7 Ma whole-rock isochron (MSWD = 1.7; initial 87Sr/86Sr = 0.7146) for the granitoids, using the 87Rb decay constant recently recommended by IUPAC-IUGS (Villa et al., 2015). This date is interpreted here as the emplacement age of those rocks, during a late stage of the Variscan D3. The granite revealed a S-type nature, namely because it is a muscovite granite, it shows a peraluminous composition (average A/CNK = 1.28), and the Sr and Nd isotope fingerprints (-8.9 ≤ ɛNd(316Ma) ≤ -7.8; +0.7105 ≤ 87Sr/86Sr(316Ma) ≤ 0.7182) fit into the composition of metasedimentary crust. The analysed phyllites show the following isotopic compositions: -9.7 ≤ ɛNd(316Ma) ≤ -8.2; +0.7148 ≤ 87Sr/86Sr(316Ma) ≤ 0.7188. Therefore, the isotope signatures, at 316 Ma, of the granite and of the studied metapelites overlap, suggesting that the parental magma was generated by anatexis of Grupo do Douro metasediments. According to their petrographic, geochemical and isotopic features, aplites and pegmatites are viewed as extreme differentiates from the granite. São Pedro das Águias metapelites show biotite zone parageneses

    The geospatial mapping of groundwater prospective zones is essential to support the needs of local inhabitants and agricultural activities in arid regions such as El-Qaà area, Sinai Peninsula, Egypt. The study aims to locate new wells that can serve to cope with water scarcity. The integration of remote sensing, geographic information systems (GIS) and geophysical techniques is a breakthrough for groundwater prospecting. Based on these techniques, several factors contributing to groundwater potential in El-Qaà Plain were determined. Geophysical data were supported by information derived from a digital elevation model, and from geologic, geomorphologic and hydrologic data, to reveal the promising sites. All the spatial data that represent the contributing factors were integrated and analyzed in a GIS framework to develop a groundwater prospective model. An appropriate weightage was specified to each factor based on its relative contribution towards groundwater potential, and the resulting map delineates the study area into five classes, from very poor to very good potential. The very good potential zones are located in the Quaternary deposits, with flat to gentle topography, dense lineaments and structurally controlled drainage channels. The groundwater potential map was tested against the distribution of groundwater wells and cultivated land. The integrated methodology provides a powerful tool to design a suitable groundwater management plan in arid regions.

    The Khunik prospecting area is located 106 km south of Birjand in eastern Iran, and is considered as an epithermal gold prospecting area. The mineralization is related to subvolcanic rocks. There are several outcrops of subvolcanic intrusions in the area which intruded into Paleocene-Eocene volcanic rocks (andesite, trachy-andesite and pyroclastic rocks). Petrographic studies indicate that subvolcanic rocks consist mainly of diorite, monzonite, quartz-monzonite, monzodiorite and quartz-monzodiorite. Mineralogically, these rocks contain plagioclase, K-feldspar, amphibole, pyroxene, biotite and quartz. Geochemically, they have features typical of high-K calk-alkaline to shoshonitic and are metaluminous, and also belong to magnetite granitoid series (I-type). Primitive mantle normalized trace element spider diagrams display enrichment in LILE, such as Rb, Ba, and Cs, compared to HFSE. Chondrite-normalized REE plots show moderately LREE enriched patterns (7.45 < LaN/YbN < 10.54), and no significant Eu anomalies. Tectonic discrimination diagrams also show affinities with modern convergent margin magmas, suggesting that magmas of Khunik area formed in volcanic arc setting related to subduction of the oceanic crust under the Lut Block plate. The initial 87Sr/86Sr ratios (0.704196-0.704772) and εNdi values (+1.3 to +3.3) are compatible with an origin of the parental melts in a supra-subduction mantle wedge. Zircon U-Pb dating by LA-ICP-MS indicates the age of 38 ± 1 Ma (late Eocene) for subvolcanic units that are related to mineralization. A biotite granodiorite porphyry is the testimony of the youngest magmatic activity in the area, with an age of 31 ± 1 Ma (early Oligocene). The represented dates are interpreted as magmatic crystallization ages of subvolcanic intrusions.

    The Shamanikha-Stolbovsky gold cluster is located in the North-East of Russia, in the basin of the Kolyma River. In 1933, gold placers were discovered there, but the search for significant gold targets for more than 50 years did not give positive results. In 2009-2011, geochemical and geophysical studies, mining and drilling were conducted within this cluster. Geochemical exploration was carried out in a modification based on superimposed secondary sorption-salt haloes (sampling density of 250x250 m, 250x50 m, 250x20 m) using the superfine fraction analysis method (SFAM) because of complicated landscape conditions (thick Quaternary sediments, widespread permafrost). The method consists in the extraction of superfine fraction (quartz formation are identified within the anomalous geochemical field core zone. 3. In all these prospects, mining and drilling penetrated gold ore bodies within the identified potentially gold zones. The Nadezhda target now has the status of gold deposit.

    Showings of magnetite, copper, and possible nickel mineralization in the Hindubagh chromite mining district are near Wulgai and Tor Tangi. Several hundred samples of clastic material from dry streambeds in these areas were sieved for the minus-80-mesh fraction and analyzed for copper using 2, 2'-biquinoline and for nickel using alpha-furildioxime. The copper threshold is 75 ppm, and the nickel threshold is 400 ppm. A geochemical map has been prepared that shows nine areas of anomalously high copper and six areas of high nickel. The nickel anomalies may represent secondary dispersion patterns derived from the erosion of nickeliferous ultramafic rocks of the Hindubagh intrusive complex. Copper showings in and near four of the anomalous copper areas indicate that detailed geological investigation and detailed geochemical sampling of rocks, soil, and unconsolidated clastic material are required to determine the source of the anomalies.

    This article presents a detailed analysis of the economic efficiency of peat utilization for generating electricity and heat in Russian rural areas and decentralized power consumption areas on the basis of the comparison of power tariffs (prices) and full costs of peat-based electricity and heat production. The research was performed using the model-information complex detailed with respect to municipal areas and major peat deposits that was developed at the Energy Institute, National Research University Higher School of Economics. It is shown that the firing of lignin helium fuel (LHF) granules that are made from peat extracted by the excavating method according to the new, patented technology is considered most efficient. In nongasified areas, the total cost of heat power that is generated in new boiler houses on the basis of LHF granules is often lower than the total heat cost for the gasification of the area and construction of gas boiler houses. In some cases, the heat cost in gasified areas is lower when using a boiler house based on LHF granules than that provided by the conversion of a boiler house to gas fuel. It is also shown that the construction of peat-based heat sources with the overall power of up to 27600 GJ/h that generate a heat power of up to 167.5 million GJ/year will be economically efficient in the coming years, provided that the tariffs for energy sources remain the same. Taking into account the supportive measures that were accepted on a legislative basis in July 2016, sources with the total power of up to 70 GW may be effective for peat-based plants with combined heat-andpower generation. To stimulate the utilization of peat in decentralized power consumption areas and rural areas located in the vicinity of deposits of this fuel type, it is also suggested to make amendments in the normative legal base.

    Full Text Available We conducted a prospective, longitudinal study of seasonality in a vulnerable population, i.e., African students who migrated to a temperate climate. Consistent with previous cross-sectional studies, we hypothesized lower mood and energy, and higher appetite and weight, in fall/winter than in spring/summer. Four cohorts of African students attending a year-long nursing school program without vacation in Washington, D.C., were assessed monthly for 1 year. Forty-three subjects (mean age = 33.46 ± 6.25, consisting of predominantly females (76.7%, completed the study. The cohorts began their academic program in different seasons (one each in winter, spring, summer, and fall, inherently minimizing confounding influences on seasonality, such as academic and immigration stress, as well as allowing adjustment for an order effect. At each assessment, students completed three 100-mm visual analog scales for mood, energy, and appetite, and were weighed on a digital scale. For each standardized dependent variable, a repeated measure ANOVA was used and, if a significant effect of month was identified, averages for spring/summer and fall/winter were compared using paired ttests. In addition, a mixed model for repeated measures was applied to raw (nonstandardized data. Body weight was significantly higher in fall/winter than in spring/summer (p < 0.01. No seasonal differences in mood, energy, or appetite were found. Benefiting from certain unique features of our cohorts allowing adjustment for order effects, this is the first study to identify a seasonal variation in body weight with a peak in winter using longitudinal monthly measurements.

A new channel, the Yangtze harbor, will be dug out to a depth of 20 m below sea level in order to connect the existing Maasvlakte harbor area with the new harbor area under construction. The upper part of the sediment, which was dredged out in order to create the new channel, consisted mainly of marine offshore sands. In the lower part, at a depth of about 17-22 m below the Dutch Ordnance Datum (NAP), Late Weichselian fluvial and aeolian sands and Early Holocene deltaic deposits of the Rhine - Meuse were present. From earlier dredging activities in the Maasvlakte area it was known that the Late Weichselian / Early Holocene deposits contain Late Paleolithic and Early Mesolithic artefacts. The deepening of the Yangtze harbor would affect the Late-Weichselian / Early Holocene deposits and destroy the archaeologically valuable objects in these layers. The aim of the archaeological Yangtze harbor project was to predict those locations where archaeological heritage from the Stone Age could be found. A geological-geogenetic approach was applied in order to determine the optimal palaeo-environmental locations for man to settle. A 3D palaeolandscape model was constructed of the harbor area; an area which was about 0.5 km wide and 3 km long. Given this palaeolandscape model, the potential archaeological sites were selected. The multidisciplinary prospection research was carried out in several steps. After each research step the strategy of the following research phase was determined

    This paper reviewed existing literatures on land use change since the demonstration phase of the Three Gorges Project and found that reservoir inundation,migration resettlement,urban relocation,and post-supporting construction were first paid more attention to,when analyzing the driving forces of land use change in the migration area.However,at the post-migration period (the end of migration resettlement),above-mentioned drivers had not obviously driven land use change,but the evolutions of "migration demands" replacing them increasingly became the major drivers of land use change in the migration area.Therefore,the future priority fields of land use explanations in the migration area,Three Gorges Project were (1) identifying the corresponding relationships between the spatial distributions of land use change and migration resettlement and indigenous inhabitants; (2) understanding the change of "migration demands" and their causing "indigenous inhabitants' demands"being how to drive land use transforms; (3) finding the driving processes of the conflict and exclusion between immigrants and indigenous inhabitants,and the transfer of immigrants and indigenous inhabitants on land use change; and (4) measuring the dynamic feedback of "migration demands" at different stages on the processes,directions and their corresponding impacts of land use change in order to building the coupling framework among "migration demands",driver behaviors,and land use.This paper presents a new access for the explanation of land use change and also supplies scientific proofs to obtain adaptive decision-making to optimize land use patterns in the migration area,Three Gorges Project.

    Full Text Available Recently, in Indonesia gold exploration activities  are not only focused along volcanic-magmatic belts, but also starting to shift along metamorphic and sedimentary terrains. The study area is located in Rumbia mountains, Bombana Regency, Southeast Sulawesi Province. This paper is aimed to describe characteristics of alteration and ore mineralization associated  with metamorphic rock-related gold deposits.  The study area is found the placer and  primary gold hosted by metamorphic rocks. The gold is evidently derived from gold-bearing quartz veins hosted by Pompangeo Metamorphic Complex (PMC. These quartz veins are currently recognized in metamorphic rocks at Rumbia Mountains. The quartz veins are mostly sheared/deformed, brecciated, irregular vein, segmented and  relatively massive and crystalline texture with thickness from 1 cm to 15.7 cm. The wallrock are generally weakly altered. Hydrothermal alteration types include sericitization, argillic, inner propylitic, propylitic, carbonization and carbonatization. There some precious metal identified consist of native gold and ore mineralization including pyrite (FeS2, chalcopyrite (CuFeS2, hematite (Fe2O3, cinnabar (HgS, stibnite (Sb2S3 and goethite (FeHO2. The veins contain erratic gold in various grades from below detection limit <0.0002 ppm to 18.4 ppm. Based on those characteristics, it obviously indicates that the primary gold deposit present in the study area is of orogenic gold deposit type. The orogenic gold deposit is one of the new targets for exploration in Indonesia

    The typical dysplastic hip joint is characterised by maldirection of the acetabulum and femoral neck, insufficient coverage of the femoral head focally and globally and erosions of the limbus acetabuli (1). An unknown number of persons with hip dysplasia will suffer from pain in hip or groin, decreased hip function and development of osteoarthritis at a young age. The Bernese periacetabular osteotomy is performed to prevent osteoarthritis in patients with hip dysplasia and has been carried out at Aarhus University Hospital, Denmark since 1996 with more than 500 osteotomies performed. Throughout the years, research and quality improvement of the treatment has taken place and this PhD thesis is part of that process. The aims of this PhD thesis were to evaluate outcome aspects after periacetabular osteotomy in terms of I) estimating the projected loadbearing surface before and after periacetabular osteotomy, II) estimating bone density changes in the acetabulum after periacetabular osteotomy, III) developing a technique to precisely and efficiently estimate the thickness of the articular cartilage in the hip joint and IV) examining the stability of the re-orientated acetabulum after periacetabular osteotomy. In study I, we applied a stereologic method based on 3D computed tomography (CT) to estimate the projected loadbearing surface in six normal hip joints and in six dysplastic hips. The dysplastic hips were CT scanned before and after periacetabular osteotomy. We found that the average area of the projected loadbearing surface of the femoral head preoperatively was 7.4 (range 6.5-8.4) cm2 and postoperatively 11 (9.8-14.3) cm2. The area of the projected loadbearing surface was increased significantly with a mean of 49% (34-70%) postoperatively and thus comparable with the load-bearing surface in the normal control group. Double measurements were performed and the error variance of the mean was estimated to be 1.6%. The effect of overprojection, on the projected

    Full Text Available The process of listing a World Heritage Area (WHAc in developing countries is often much more complex than in the West. Often all stakeholders are not taken into consideration and there is a lack of understanding of the concept of World Heritage and what it entails. This is particularly true for stakeholders who live in or adjacent to the proposed WHA, such as local communities. This paper presents a case study of Kokoda and the Owen Stanley Ranges, currently a tentative World Heritage site, to show the complexities in stakeholder collaboration and attribution in the process of World Heritage designation. Six key stakeholders were identified in the study. Upon examination of four attributes of stakeholders: power; legitimacy; urgency; and proximity, it was found that all stakeholders in this case study have a high legitimacy in the listing process however only the local community holds high levels of power, urgency and proximity. Additionally it was found that several stakeholders, like the private sector, have too many weak relationships with other stakeholders, resulting in a lack of communication. These findings present the first step in understanding how it might be possible to improve the listing process of World Heritage Sites in developing countries through effective stakeholder collaboration.

    Atrial fibrillation (AF) is a common form of arrhythmia that is associated with increased risk of stroke and mortality. Detecting AF before the first complication occurs is a recognized priority. No previous studies have examined the feasibility of undertaking AF screening using a telehealth surveillance system with an embedded cloud-computing algorithm; we address this issue in this study. The objective of this study was to evaluate the feasibility of AF screening in nonmetropolitan areas using a telehealth surveillance system with an embedded cloud-computing algorithm. We conducted a prospective AF screening study in a nonmetropolitan area using a single-lead electrocardiogram (ECG) recorder. All ECG measurements were reviewed on the telehealth surveillance system and interpreted by the cloud-computing algorithm and a cardiologist. The process of AF screening was evaluated with a satisfaction questionnaire. Between March 11, 2016 and August 31, 2016, 967 ECGs were recorded from 922 residents in nonmetropolitan areas. A total of 22 (2.4%, 22/922) residents with AF were identified by the physician's ECG interpretation, and only 0.2% (2/967) of ECGs contained significant artifacts. The novel cloud-computing algorithm for AF detection had a sensitivity of 95.5% (95% CI 77.2%-99.9%) and specificity of 97.7% (95% CI 96.5%-98.5%). The overall satisfaction score for the process of AF screening was 92.1%. AF screening in nonmetropolitan areas using a telehealth surveillance system with an embedded cloud-computing algorithm is feasible.

    2016-01-01

    PURPOSE Early loading of implant can be determined by excellent primary stability and characteristic of implant surface. The implant system with recently improved surface can have load application 4-6 weeks after installing in maxilla and mandible. This study evaluated the effect of healing period to the stability of hydrophilic tapered-type implant at maxillary posterior area. MATERIALS AND METHODS This study included 30 patients treated by hydrophilic tapered-type implants (total 41 implants at maxilla) and classified by two groups depending on healing period. Group 1 (11 patients, 15 implants) was a control group and the healing period was 12 weeks, and Group 2 (19 patients, 26 implants) was test group and the healing period was 6 weeks. Immediately after implant placement, at the first impression taking, implant stability was measured using Osstell Mentor. The patients also took periapical radiographs after restoration delivery, 12 months after restoration and final followup period. The marginal bone loss around the implants was measured using the periapical radiographs. RESULTS All implants were survived and success rate was 97.56%. The marginal bone loss was less than 1mm after 1 year postoperatively except the one implant. The stabilities of the implants were not correlated with age, healing period until loading, insertion torque (IT), the diameter of fixture and the location of implant. Only the quality of bone in group 2 (6 week) was correlated with the stability of implant. CONCLUSION Healing period of 6 weeks can make the similar clinical prognosis of implants to that of healing period of 12 weeks if bone quality is carefully considered in case of early loading.

    Full Text Available Eastern Iran has great potential for porphyry copper deposits, as a result of its past subduction zone tectonic setting that lead to extensive alkaline to calc-alkaline magmatic activity in Tertiary time. Maherabad is the first porphyry Cu-Au prospecting area which is discovered in eastern Iran. This is related to a succession o f monzonitic to dioritic porphyries stocks that were emplaced within volcanic rocks. Monzonitic porphyries have basic role in mineralization. Hydrothermal alteration zones are well developed including potassic, sericitic-potassic, quartz-sericite-carbonate-pyrite, quartz-carbonate-pyrite, silicified-propylitic, propylitic, carbonate and silicified zones. Mineralization occurs as Disseminated, stockwork and hydrothermal breccia. Based on early stage of exploration, Cu is between 179- 6830 ppm (ave. 3200 ppm and Au is up to 1000 ppb (ave. 570 ppb. This prospect is gold- rich porphyry copper deposit. Laser-ablation U-Pb dating of two samples from ore-related intrusive rocks indicate that these two monzonitic porphyries crystallized at 39.0 ± 0.8 Ma to 38.2 ± 0.8 Ma, within a short time span of less than ca. 1 Ma during the middle Eocene. This provides the first precise ages for metallogenic episode of porphyry-type mineralization. Also, the initial 87Sr/86Sr and (143Nd/144Ndi was recalculated to an age of 39 Ma. Initial 87Sr/86Sr ratios for monzonitic rocks are 0.7047-0.7048. The (143Nd/144Ndi isotope composition are 0.512694-0.512713. Initial ε Nd isotope values 1.45-1.81. Based on isotopic data the magma had originated beyond the continental crust. The study will be used for tectonic-magmatic setting and evolution of eastern Iran.

    Series regarding the clinical characteristics of molluscum contagiosum (MC) are retrospective and concern small defined populations seen in a hospital setting. We prospectively studied patients under 15 years of age with MC seen in 25 private dermatology practices in the greater Paris area during 1 year. Six hundred fifty patients were included. The mean age was 6 years. Of the patients, 30.5% had had MC in the past, 53% had 5-20 MC, 43% had a history of atopic dermatitis (AD), 5% were using topical steroids, 25.5% had coexistent AD, 13% had giant MC (>5 mm), 21% had inflammatory MC, and 19% had MC surrounded by eczema. Bathing with siblings was associated with a higher number of MC. A history of AD was associated with the presence of MC surrounded by eczema. The use of topical steroids was associated with a higher risk of relapse. There was no relation between environmental factors (MC in surrounding people, going to the swimming pool, sports practice) and the number of lesions or between environmental factors and the number of recurrences. Atypical lesions are frequent. Bathing with siblings is associated with a higher number of MC. Topical steroid use increases the risk of relapses. AD prevalence is higher than in the general population. Copyright © 2011 S. Karger AG, Basel.

    Wide-area transepithelial sampling (WATS) with computer-assisted 3-dimensional analysis is a sampling technique that combines abrasive brushing of the Barrett's esophagus (BE) mucosa followed by neural network analysis to highlight abnormal-appearing cells. We performed a randomized trial of referral BE patients undergoing surveillance at 16 medical centers. Subjects received either biopsy followed by WATS, or vice versa. The primary outcome was rate of detection of HGD/EAC using WATS in conjunction with biopsy compared with biopsy alone using standard histopathologic criteria. Secondary aims included evaluating neoplasia detection rates (1) based on the procedure order (WATS vs biopsy first) (2) of each procedure separately, and (3) the additional time required for WATS. One hundred sixty patients (mean age 63.4 years, 76% male; 95% white) completed the trial. The median circumferential and maximal BE extents were 1.0 (IQR: 0.0-5.0) cm and 4.0 (IQR, 2.0-8.0) cm, respectively. The diagnostic yield for biopsy alone was as follows: HGD/EAC, 7 (4.4%); low-grade dysplasia (LGD), 28 (17.5%); non-dysplastic BE (NDBE), 106 (66.25%); and no BE, 19 (11.9%). The addition of WATS to biopsy yielded an additional 23 cases of HGD/EAC (absolute increase, 14.4%; 95% CI, 7.5%-21.2%). Among these 23 patients, 11 were classified by biopsy as NDBE, and 12 as LGD/IND; 14 received biopsy and 9 WATS first (p=NS) and the majority (n=21; 91.7%) had a prior dysplasia history. WATS added average of 4.5 minutes to the procedure. Results of this multicenter, prospective, randomized trial demonstrate that the use of WATS in a referral BE population increases the detection of HGD/EAC.

    Full Text Available Abstract Background Few studies have investigated how area-level deprivation influences the relationship between individual disadvantage and suicide mortality. The aim of this study was to examine individual measures of material and social disadvantage in relation to suicide mortality in Canada and to determine whether these relationships were modified by area deprivation. Methods Using the 1991-2001 Canadian Census Mortality Follow-up Study cohort (N = 2,685,400, measures of individual social (civil status, family structure, living alone and material (education, income, employment disadvantage were entered into Cox proportional hazard models to calculate hazard ratios (HR and 95% confidence intervals (CI for male and female suicide mortality. Two indices of area deprivation were computed - one capturing social, and the other material, dimensions - and models were run separately for high versus low deprivation. Results After accounting for individual and area characteristics, individual social and material disadvantage were associated with higher suicide mortality, especially for individuals not employed, not married, with low education and low income. Associations between social and material area deprivation and suicide mortality largely disappeared upon adjustment for individual-level disadvantage. In stratified analyses, suicide risk was greater for low income females in socially deprived areas and males living alone in materially deprived areas, and there was no evidence of other modifying effects of area deprivation. Conclusions Individual disadvantage was associated with suicide mortality, particularly for males. With some exceptions, there was little evidence that area deprivation modified the influence of individual disadvantage on suicide risk. Prevention strategies should primarily focus on individuals who are unemployed or out of the labour force, and have low education or income. Individuals with low income or who are living alone in

    The integrity of prospective memory (PM) is likely crucial for independent human behavior. PM refers to the ability to execute an intention after a certain delay. Its impaired functioning may significantly affect the correct execution of common daily activities, such as taking a pill at a certain time or complying with future plans. The results of recent studies indicate that PM is impaired pervasively and early in individuals with mild cognitive impairment (MCI) and Parkinson's disease (PD). In this study, we reviewed studies investigating the characteristics of PM disorders in these individuals and the potential for cognitive rehabilitation. The PM profiles of individuals with MCI and PD indicate that interventions aimed at enhancing the different cognitive processes underlying their PM disorders could be useful. At the current state of the art, however, no evidence-based protocols are available. Therefore, the discussion proposed here should be considered an attempt to identify some valuable perspectives for future research and interventions.

    To detect cervical carotid stenosis as a candidate for carotid endarterectomy (CEA), the authors attempted a prospective trial by exploring stenosis for one year in a rural district with a population of 20,000, employing helical CT angiography which apparently displayed three-dimensional reconstructed images of the carotid bifurcation. Thirty-three patients, 24 males and 9 females, with a mean age of 71.8 years, suffering from TIA, RIND or stroke were investigated for their carotid systems. The clinical symptoms of the patients were briefly as follows: motor weakness in 30 cases, dysarthria in 8 cases and aphasia in 4 cases; and 6 of 22 (27%) stroke cases had previously suffered an episode of TIA. The risk factors of the whole group of patients were hypertension in 13 cases, diabetes mellitus in 6, heart disease in 17, and hypercholesteremia in 4. Helical CT angiography was performed in 11 cases of TIA, 2 cases of RIND, and 16 cases of stroke. Only 3 cases of the TIA group and 3 cases of the stroke group were found to have extracranial carotid stenosis of more than 50%, which subsequently required conventional angiography. For the detection of stenosis, CT angiography was beneficial as well as conventional angiography. Finally, CEA was performed in 2 of 3 cases with severe carotid stonosis in the TIA group, while such cases in the stroke group were only observed. The above results meant that the occurrence of extracranial carotid stenosis was 6 out of 6,589 elderly inhabitants (over 60 years old), although the possible detection rate of candidates for CEA was 2 out of 20,000 population per year.

    Objective:To evaluate inhouse developed SEVA TB peroxidase enzyme immunoassay using cocktail of mycobacterial excretory-secretory antigens (ES-31, ES-43&EST-6) for antibody detection and their affinity purified antibodies for antigen detection in tuberculosis suspected patients. Methods:Inhouse developed SEVA TB peroxidase enzyme immunoassay was evaluated prospectively in 73 suspected pulmonary and 46 extra-pulmonary tuberculosis patients during November 2008~March 2009 in a tertiary hospital located in rural area. Results: Assay on prospective analysis showed 100% correlation of pulmonary tuberculosis (PTB) and extra-pulmonary tuberculosis (EPTB) acid fast bacilli positivity and antitubercular treatment in 11 cases. Thirty nine PTB and 12 EPTB cases showed negative for ELISA test and were also not given antitubercular therapy. However 30 PTB and 27 EPTB cases showing ELISA positivity were neither acid fast bacilli positive nor antitubercular therapy treated. These cases may possibly have dormant infection and need further diagnosis. In EPTB cases ELISA was observed to be more useful than AFB smear test. Conclusions:This inhouse developed user-friendly peroxidase ELISA can be used as an adjunct test of smear microscopy or culture techniques for routine screening of patients suspected of PTB or EPTB.

    Full Text Available In this research, recognition of karstic water-bearing zones using the management of exploration data in Kal-Qorno valley, situated in the Tepal area of Shahrood, has been considered. For this purpose, the sequential exploration method was conducted using geological evidences and applying remote sensing and geoelectrical resistivity methods in two major phases including the regional and local scales. Thus, geological structures and lithological units in regional scale have been investigated for groundwater potential. In this regard, suitable potential maps have been provided in the geographical information system (GIS environment, using fuzzy data-driven and knowledge-driven methods. To obtain the final karstic water potential model, the prepared maps were combined using fuzzy ‘AND’ operator. In the local scale, geoelectrical surveys were conducted in the recognized high potential zones. Consequently, the results of geological investigations, analysis of lineaments extracted from satellite imagery and geoelectrical resistivity data modeling and interpretation were integrated to decide on the position of high yield extraction wells. As a result, karstic water zones in the study area were identified, and based on that, two suitable drilling locations to access and extract karstic groundwater in the study area have been suggested.

    Full Text Available Abstract Background Although causing substantial morbidity, the burden of pneumococcal disease among older children and adults in Africa, particularly in rural settings, is not well-characterized. We evaluated pneumococcal bacteremia among 21,000 persons ≥5 years old in a prospective cohort as part of population-based infectious disease surveillance in rural western Kenya from October 2006-September 2008. Methods Blood cultures were done on patients meeting pre-defined criteria - severe acute respiratory illness (SARI, fever, and admission for any reason at a referral health facility within 5 kilometers of all 33 villages where surveillance took place. Serotyping of Streptococcus pneumoniae was done by latex agglutination and quellung reaction and antibiotic susceptibility testing was done using broth microdilution. We extrapolated incidence rates based on persons with compatible illnesses in the surveillance population who were not cultured. We estimated rates among HIV-infected persons based on community HIV prevalence. We projected the national burden of pneumococcal bacteremia cases based on these rates. Results Among 1,301 blood cultures among persons ≥5 years, 52 (4% yielded pneumococcus, which was the most common bacteria isolated. The yield was higher among those ≥18 years than 5-17 years (6.9% versus 1.6%, p 95%. The crude rate of pneumococcal bacteremia was 129/100,000 person-years, and the adjusted rate was 419/100,000 person-years. Nineteen (61% of 31 patients with HIV results were HIV-positive. The adjusted rate among HIV-infected persons was 2,399/100,000 person-years (Rate ratio versus HIV-negative adults, 19.7, 95% CI 12.4-31.1. We project 58,483 cases of pneumococcal bacteremia will occur in Kenyan adults in 2010. Conclusions Pneumococcal bacteremia rates were high among persons ≥5 years old, particularly among HIV-infected persons. Ongoing surveillance will document if expanded use of highly-active antiretroviral

    In order to discuss effectiveness of physical exploration in the Sakonishi prospect in the Hida area, physical exploration was carried out by utilizing bored wells. This area contains the Kamioka mine, one of the major base metal mines in Japan, where electrical exploration has been attempted several times in the past. No effective results have been obtained, however, because specific resistance contrast between mine beds and base rocks is too small, and the topography is too steep making site workability inferior. As part of the investigations on geological structures over wide areas, electrical logging (specific resistance and natural potential) was performed in fiscal 1995 and 1996 by utilizing the boreholes. Induced polarization logging was also conducted on the same boreholes. A traverse line on the ground with a length of 600 m and boreholes were used to execute specific resistance tomography. Clear extraction was possible on a fault structure which is thought related with limestone distribution and mine bed creation. However, it was not possible to identify upward continuity of zinc ores expected in the exploration. Because of not large a specific resistance contrast between zinc ores and base rocks, it is difficult to find mine bed locations only from the information on the specific resistance. 5 refs., 5 figs., 1 tab.

    Launched with enthusiasm and determination in 1957, The European Atomic Energy Community (EAEC - EURATOM), which aimed to promote the development of a 'powerful nuclear industry' in Europe, has not ultimately fulfilled the wishes of its founding fathers. Rapidly, and on a topic as strategic as the peaceful use of the atom, national reflexes prevailed. The Chernobyl disaster, in 1986, also substantially slowed down the use of nuclear energy in Europe. Nuclear safety and radiation protection have followed two different paths. Backed by Chapter III of the EURATOM treaty, over time the EAEC has developed a substantial legislative corpus on radiation protection. Meanwhile, and strange as it may seem, nuclear safety has remained the poor relation, on the grounds that the treaty does not grant EURATOM competence in the area. It is true that legislation was adopted in reaction to Chernobyl, but for a long time there was no specific regulation of nuclear safety in the EU. The European nuclear safety and radiation protection area owes its construction to Community mechanisms as well as to informal initiatives by safety authorities. Today, more than ever, this centre provides consistency, an overall balance which should both strengthen it and impose it as an international reference. Progress can now be expected on waste management, radiation protection and the safety objectives of new reactors. (author)

    The purpose of this study was to demonstrate clinical outcomes of sandblasted, large-grit, acid-etched (SLA)-surfaced tapered implants when early loaded in partially edentulous spaces in the maxilla. SLA-surfaced implants were placed in participants in the maxillary posterior edentulous area. At the time of definitive restoration, participants were allocated either to group 1 (3-month loading group) or group 2 (6-month loading group). A total of 36 participants (18 people [35 implants] in group 1 and 18 [33 implants] in group 2) were analyzed. Clinical outcomes, including survival rate and peri-implant parameters such as marginal bone loss were measured 1 year after loading. The survival rate was 97.0% in group 1 and 100% in group 2. Marginal bone loss was 0.22 ± 0.34 mm in group 1 and 0.17 ± 0.25 mm in group 2 at 1 year after loading (P = .488). There were no significant differences between groups in keratinized mucosal width (P = .206), Plaque Index (P = .677), or Gingival Index (P = .558). With adequate remaining bone height and primary implant stability achieved, the 3-month early loading of SLA-surface tapered implants may be a viable choice when restoring posterior maxillary edentulous areas.

    The Hatu area, West Junggar, Xinjiang, China, is situated at a potential gold-copper mineralization zone in association with quartz veins and small granitic intrusions. In order to identify the alteration zones and mineralization occurrences in this area, the Landsat Thematic Mapper (TM) and Enhanced Thematic Mapper (ETM+), Quickbird, Hyperion data and laboratory measured spectra were combined in identifying structures, alteration zones, quartz veins and small intrusions. The hue-saturation-intensity (HSI) color model transformation was applied to transform principal component analysis (PCA) combinations from R (Red), G (Green) and B (Blue) to HSI space to enhance faults. To wipe out the interference of the noise, a method, integrating Crosta technique and anomaly-overlaying selection, was proposed and implemented. Both Jet Propulsion Laboratory Spectral Library spectra and laboratory-measured spectra, combining with matched filtering method, were used to process Hyperion data. In addition, high-resolution Quickbird data were used for unraveling the quartz veins and small intrusions along the alteration zones. The Baobei fault and a SW-NE-oriented alteration zone were identified for the first time. This study eventually led to the discovery of four weak gold-copper mineralized locations through ground inspection and brought new geological knowledge of the region’s metallogeny.

    Thirty-nine elements in humus and till matrix were compared at 109 sites overlying Ag-As-Cu-Mo-Pb-Zn mineralized occurrences in northeastern New Brunswick to assess humus for anomaly identification. Humus element concentrations were not consistently correlative with maximum or minimum concentrations found in the underlying till or bedrock. The humus demonstrated significantly higher mean elemental concentrations than the till for six specific elements: 9 times greater for Mn, 6 times greater for Cd, 5 times greater for Ag and Pb, 3 times greater for Hg, and double the concentration of Zn. Spatial dispersal patterns for these elements were much larger for humus content than that exhibited by the till matrix analysis, but did not delineate a point source. For elements in till, the highest concentrations were commonly found directly overlying the underlying mineralized bedrock source or within one km down-glacier of the source. The complexity of the humus geochemical patterns is attributed to the effects of post-glacial biogenic, down-slope hydrodynamic and solifluction modification of dispersed mineralization in the underlying till, and the greater capacity of humus to adsorb cations and form complexes with some elements, relative to the till matrix. Humus sampling in areas of glaciated terrain is considered to be mostly valuable for reconnaissance exploration as elements can be spatially dispersed over a much larger area than that found in the till or underlying bedrock. ?? 2009 Elsevier B.V.

    To evaluate the outcomes with respect to long-term survival and toxicity in patients with nasopharyngeal carcinoma (NPC) treated in a European country with low incidence. A prospective observational study carried out by the AIRO Head and Neck group in 12 Italian institutions included 136 consecutive patients treated with radiotherapy (RT) ± chemotherapy (CHT) for NPC (without distant metastasis) between January 1, 2008 and December 31, 2010. The disease-specific survival (DSS), overall survival (OS), and disease-free survival (DFS) at 5 years were 92 (±2), 91 (±3), and 69 % (±5 %), respectively. Distant failure was the most frequent modality of relapse. The local, regional, and locoregional control at 5 years were 89 (±3), 93 (±3), and 84 % (±4 %), respectively. The incidence of acute and late toxicity and the correlations with different clinical/technical variables were analyzed. Neoadjuvant CHT prolongs radiotherapy overall treatment time (OTT) and decreases treatment adherence during concomitant chemoradiotherapy. An adequate minimum dose coverage to PTV(T) is a predictive variable well related to outcome. Our data do not substantially differ in terms of survival and toxicity outcomes from those reported in larger series of patients treated in countries with higher incidences of NPC. The T stage (TNM 2002 UICC classification) is predictive of DSS and OS. The GTV volume (T ± N) and an adequate minimum PTV(T) coverage dose (D95 %) were also identified as potential predictive variables. Sophisticated technologies of dose delivery (IMRT) with image-guided radiotherapy could help to obtain better minimum PTV(T) coverage dose with increased DFS; distant metastasis after treatment still remains an unresolved issue.

    Full Text Available Introduction The Shah Soltan Ali area is located 85 km southwest of Birjand in the South Khorasan province. This area is part of the Tertiary volcanic-plutonic rocks in the east of the Lut block. The Lut block is bounded to the east by the Nehbandan and associated faults, to the north by the Doruneh and related faults (Sabzevar zone, to the south by the Makran arc and Bazman volcanic complex and to the west by the Nayband Fault. The Lut block is the main metallogenic province in the east of Iran (Karimpour et al., 2012, that comprises of numerous porphyry Cu and Cu–Au deposits, low and high sulfidation epithermal Au deposits, iron oxide deposits, base-metal deposits and Cu–Pb–Zn vein-type deposits. The geology of Shah Soltan Ali area is dominated by volcanic rocks, comprised of andesite and basalt, which are intruded by subvolanic units such as monzonite porphyry, monzodiorite porphyry and diorite porphyry. Materials and methods 1. 170 thin sections of the rock samples as well as 25 polished and thin polished sections were prepared for petrography, alteration and mineralization. 2. Twenty five samples were analyzed for Cu, Pb, Zn, Sb, Mo and As elements by the Aqua regia method in the Zarazama laboratory in Tehran, Iran. 3. Nine samples were analyzed for trace elements [including rare earth elements (REEs]. As a result of these analyses, trace elements and REE were determined by inductively coupled plasma mass spectrometry (ICP-MS in the ACME Analytical Laboratories (Vancouver Ltd., Canada. 4. Ten samples were analyzed for major elements by wavelength dispersive X-ray fluorescence spectrometry in the East Amethyst laboratory in Mashhad, Iran. 5. Five samples were analyzed for Firre Assay analysis in the Zarazma Laboratory in Tehran, Iran. 6. The results of XRD analysis were used for 4 samples. Discussion and results Petrographic studies indicate that subvolcanic rocks consist of diorite porphyry, monzonite porphyry and monzodiorite

    The objective of this study was to examine predictors for readmissions in patients admitted to a general hospital emergency ward for suicide attempts before and after organizational changes potentially affecting the chain of care. Socio-demographic and clinical variables were collected by clinicians from 1997 thru 2007. Data from the periods before and after 2004--when the hospital changed its catchment area--were compared. A substantial increase in readmission rates in the period after the organizational change was observed. This increase was not associated with any of the socio-demographic or clinical patient characteristics. Although no causal connection can be inferred, the observed association between organizational change and readmission rates could indicate that established post-discharge care systems for suicide attempters may be vulnerable to such change.

    Ultrasound measurement of the antral cross-sectional area of the stomach, performed in the supine position, has been described for preoperative assessment of gastric content in the adult, but, to date, no study has determined the cut-off value of the antral area for the diagnosis of an empty stomach in the parturient. Nevertheless, previous studies in parturients have reported that the use of a simple qualitative grading scale (0 to 2) was reliable for the estimation of the gastric fluid volume. However, this qualitative grading score requires turning the parturient into the right lateral decubitus position for the ultrasound examination, something which may not be easily feasible, particularly in the case of an obstetric emergency. To calculate the cut-off value of the antral area, measured in the supine position during established labour, for the diagnosis of 'empty' stomach. A prospective cohort study. Hospices Civils de Lyon, Hôpital Femme Mère Enfant, Lyon, France. Seventy-three women in established labour. For each parturient, ultrasound assessment of gastric contents was performed in the supine and right lateral decubitus position and scored 0 to 3 on a qualitative grading scale. This assessment was followed by ultrasound measurement of the antral cross-sectional area in both the supine and right lateral positions. To assess the performance of the antral area measured in the supine position for the diagnosis of an 'empty' stomach (gastric antrum grade 0), a receiver operating characteristic curve was plotted, and the area under the receiver operating characteristic curve was calculated. Data from 73 women were analysed. For the diagnosis of grade 0, the cut-off value for the antral area measured in the supine position was 381 mm (sensitivity, 81%; specificity, 76% and negative predictive value, 80%). With a parturient lying in the supine position, a single assessment of the antral cross-sectional area may be used for the fast diagnosis of an empty

    Rhesus macaques are found ubiquitously throughout Asia, from Afghanistan to India and Thailand to southern China. They are used for an extraordinary range of biomedical and basic research. Due to their close genetic, physiologic, and metabolic similarity to humans, this species serves as an essential research tool in neuroscience, behavioral biology, reproductive physiology, neuroendocrinology, endocrinology, cardiovascular studies, pharmacology, and many other areas. Macaca mulatta tcheliensis, an endemic subspecies of rhesus macaque to China, are distributed mainly in the southern parts of the Taihangshan and Zhongtiaoshan Mountains area which was the northernmost range of rhesus macaque. These macaques, referred to as the Taihangshan macaque, live in secondary deciduous forests at elevations between 300 m and 1200 m (984 ft and 3937 ft) with a temperate climate and cold, snowy winters similar to the climate of the central, midwestern United States. Rhesus macaque are categorized into Grade II in the list Chinese Key protected animal species. Since early the 1980s, researchers had conducted some works on its population and distribution, morphology (including general morphology and skeleton morphology), ecology, microbiology, diseases, and other fields. In this article, we summarized those published works, and outlined further research needs to be done in the future. We aim to promote effective and long-term conservation on Taihangshan macaques.%猕猴广泛分布于从阿富汗到泰国和中国南部的亚洲地区.分布于中国的猕猴有6个亚种.太行山猕猴为猕猴华北亚种Macaca mulatta tcheliensis,系中国所特有,目前仅分布于河南、山西两省交界的太行山和中条山南端地区,为世界野生猕猴分布最北的种群.自20世纪80年代初期开始,学者们在数量与分布、形态学(包括普通形态学、骨骼系统形态学)、生态学、微观生物学、疾病、实验技术等方面,对太行山猕猴展开了

    Objectives To study characteristics of psychosomatic symptoms related to sterilization,to find out risk factors and their roles ascribed to psychosomatic symptoms, and toestablish a mathematic model for screening out susceptible women.Methods: This study enrolled 776 women in rural area at three counties of Linxiang,Qiyang, Changsha of Hunan province in China between February 1990 and April1992. Brief Neurosis Screening Scale (BNSS), Symptom Checklist 90 (SCL-90),sensitivity to pain, suggestibility were used to indicate subjects' psychological status.Logistic regression model and retrograde discriminant analysis were applied to developa mathematical model.Results: Prevalence of psychosomatic reactions or symptoms was 54. 8% before steril-ization, 26. 6% at three months and 16. 4% at one year after operation respectively.Psychosomatic symptoms were verified to be the result of joint effects of multiple riskfactors. The following risk factors were associated with postoperative symptoms:anger-hostility (RR= 33. 71), high suggestibility (RR= 4. 53), high neuroticism (RR= 3. 44), sensitivity to pain (RR = 2. 14) and operative sites (RR = 2. 05). A mathe-matical model to estimate the probability of developing psychosomatic symptoms in ster-ilization was established.Conclusions: More than half of women suffered from psychosomatic reactions beforeoperation, and some of them did not recover after operation. The postoperative psycho-somatic symptoms are the joint effect of multiple risk factors.

    After the Chernobyl nuclear incident in 1986, children in the Narodichesky region, located 80 km west of the Chernobyl Power Plant, were exposed to 137Cesium (137Cs). Little is known about the effects of chronic low-level radiation on humoral immune responses in children residing in contaminated areas. In four different approaches we investigated the effect of residential 137Cs exposure on immunoglobulins A, G, M, and specific immunoglobulin E in children. In a dynamic cohort (1993-1998) we included 617 children providing 2,407 repeated measurements; 421 and 523 children in two cross-sectional samples (1997-1998 and 2008-2010, respectively); and 25 participants in a small longitudinal cohort (1997-2010). All medical exams, blood collections, and analyses were conducted by the same team. We used mixed linear models to analyze repeated measurements in cohorts and general linear regression models for cross-sectional studies. Residential soil contamination in 2008 was highly correlated with the individual body burden of 137Cs. Serum IgG and IgM concentrations increased between 1993 and 1998. Children with higher 137Cs soil exposure had lower serum IgG levels, which, however, increased in the small cohort assessed between 1997 and 2010. Children within the fourth quintile of 137Cs soil exposure (266-310 kBq/m2) had higher IgM serum concentrations between 1993 and 1998 but these declined between 1997 and 2010. IgA remained stable with median 137Cs exposures related to higher IgA levels, which was corroborated in the cross-sectional study of 2008-2010. Specific IgE against indoor allergens was detected less often in children with higher 137Cs exposure. Our findings show radiation-related alterations of immunoglobulins which by themselves do not constitute adverse health effects. Further investigations are necessary to understand how these changes affect health status.

    Full Text Available Bactrocera fruit fly species are economically important throughout the Pacific. The USDA, ARS U.S. Pacific Basin Agricultural Research Center has been a world leader in promoting biological control of Bactrocera spp. that includes classical, augmentative, conservation and IPM approaches. In Hawaii, establishment of Bactrocera cucurbitae (Coquillett in 1895 resulted in the introduction of the most successful parasitoid, Psyttalia fletcheri (Silvestri; similarly, establishment of Bactrocera dorsalis (Hendel in 1945 resulted in the introduction of 32 natural enemies of which Fopius arisanus (Sonan, Diachasmimorpha longicaudata (Ashmead and Fopius vandenboschi (Fullaway were most successful. Hawaii has also been a source of parasitoids for fruit fly control throughout the Pacific region including Australia, Pacific Island Nations, Central and South America, not only for Bactrocera spp. but also for Ceratitis and Anastrepha spp. Most recently, in 2002, F. arisanus was introduced into French Polynesia where B. dorsalis had invaded in 1996. Establishment of D. longicaudata into the new world has been important to augmentative biological control releases against Anastrepha spp. With the rapid expansion of airline travel and global trade there has been an alarming spread of Bactrocera spp. into new areas of the world (i.e., South America and Africa. Results of studies in Hawaii and French Polynesia, support parasitoid introductions into South America and Africa, where B. carambolae and B. invadens, respectively, have become established. In addition, P. fletcheri is a candidate for biological control of B. cucurbitae in Africa. We review past and more

    Tuberculosis (TB), especially extrapulmonary TB is still the leading cause of fever of unknown origin (FUO) in China. However, diagnosis of TB still remains a challenge. The aim of this study was to evaluate the diagnostic value of T-SPOT.TB for etiological diagnosis of classic FUO in adult patients in a high TB endemic area. We prospectively enrolled patients presenting with classic FUO in a tertiary referral hospital in Beijing, China, to investigate the diagnostic sensitivity, specificity, predictive values and likelihood ratio of T-SPOT.TB. Clinical assessment and T-SPOT.TB were performed. Test results were compared with the final confirmed clinical diagnosis. 387 hospitalized patients (male n = 194, female n = 193; median age 46 (range 29-59) yrs) with classic FUO were prospectively enrolled into this study. These FUOs were caused by infection (n = 158, 40.8%), connective tissue disease (n = 82, 21.2%), malignancy (n = 41, 10.6%) and miscellaneous other causes (n = 31, 8.0%), and no cause was determined in 75 (19.4%) patients. 68 cases were diagnosed as active TB eventually. The sensitivity of T-SPOT.TB for the diagnosis of active TB was 70.6% (95%CI 58.9-80.1%), while specificity was 84.4% (95%CI 79.4-88.4%), positive predictive value was 55.8% (95%CI 45.3-65.8%), negative predictive value was 91.2% (95%CI 86.7-94.2%). Among these 68 active TB patients, 12 cases were culture or histology confirmed (11 cases with positive T-SPOT.TB, sensitivity was 91.7%) and 56 cases were clinically diagnosed (37 cases with positive T-SPOT.TB, sensitivity was 66.1%); 14 cases were pulmonary TB (13 cases with positive T-SPOT.TB, sensitivity was 92.9%) and 54 cases were extrapulmonary TB (35 cases with positive T-SPOT.TB, sensitivity was 64.8%). For patients presenting with classic FUO in this TB endemic setting, T-SPOT.TB appears valuable for excluding active TB, with a high negative predictive value.

    Low and middle-income countries carry over ninety per cent of the burden of injury related mortality and disability. Motorcycles are gradually becoming a major mode of transportation in Cameroon and other African countries in the absence of an organized public transport. Consequently, the contribution of motorcycle crash to injury-related deaths seems to be on the rise. Currently, data addressing motorcycle crash characteristics, pattern, and severity of motorcycle-related injuries in Cameroon are scarce. We hypothesised that head and limb injuries are the most frequent cause of morbidity and mortality and equally affect riders and pillion passengers. This hospital-based prospective pilot cohort analysis involving 405 motorcycle crashes and 621 injury victims was conducted in Laquintinie Hospital, a large centre located in an urban area in Cameroon. All motorcycle riders and passengers received in the emergency department over a 4 months period with an injury following a traffic related crash were included. Crash characteristics and type, anatomical location and severity of injuries were recorded and analysed comparing the pattern of injuries between riders and pillion passengers involved in motorcyclecrashes. This pilot analysis is expected to propose a snapshot of motorcycle injuries in Douala and will be followed by a larger analysis over a longer period. We recorded a majority of motorcycle versus car and motorcycle versus motorcycle collisions. Most of these crashes occurred over the week-end and in the night. Helmet use was almost inexistent. We observed that females aged above 40 years represented the majority of pillion passengers. This accounted for the sex-ratio of 1.1/1. A total of 1311 injuries were identified in our patients, giving a mean of 2.1 injuries per victim. The head and the limbs were the most affected anatomical areas. Riders carried a higher risk of sustaining an injury to head and neck than pillion passengers. Riders and pillion passengers

    Some recent research has suggested that health-related behaviours, such as smoking, might explain much of the socio-economic inequalities in coronary heart disease (CHD) risk. In a large prospective study of UK women, we investigated the associations between education and area deprivation and CHD risk and assessed the contributions of smoking, alcohol consumption, physical activity and body mass index (BMI) to these inequalities. After excluding women with heart disease, stroke or cancer at recruitment, 1,202,983 women aged 56 years (SD 5 years) on average, were followed for first coronary event (hospital admission or death) and for CHD mortality. Relative risks of CHD were estimated by Cox regression, and the extent to which any association could be accounted for by smoking, alcohol, physical inactivity, and BMI was assessed by calculating the percentage reduction in the relevant likelihood-ratio (LR) statistic after adjustment for these factors, separately and together. A total of 71,897 women had a first CHD event (hospital admission or death) and 6032 died from CHD during 12 years follow-up. In analyses adjusted by age, birth cohort and region of residence only, lower levels of education and greater deprivation were associated with higher risks of CHD (P heterogeneity deprivation and for deprivation were found within every level of education. Smoking, alcohol consumption, physical inactivity and BMI accounted for most of the associations (adjustment for all four factors together reduced the LR statistics for education and for deprivation by 76 % and 71 %, respectively, for first CHD event; and by 87 % and 79 %, respectively, for CHD mortality). Of these four factors, adjustment for smoking resulted in the largest reduction in the LR statistic. Given the large reduction in the predictive values of education and deprivation after adjustment for only four health-related behavioural factors recorded just at recruitment, residual confounding might plausibly

    After more than 25 years of development of nuclear power and almost 10 years of research and development in numerous areas of nonnuclear energy, there is now a good basis for judging the future prospects of energy technologies in the Federal Republic of Germany. The development of nuclear power has provided an important and economically advantageous new source of energy. Further efforts are needed to establish the nuclear fuel cycle in all stages and to exploit the potential of advanced reactors. In all other areas of energy technology, including energy conservation, new energy sources, and coal, economics has turned out to be the key problem, even at today's energy prices. Opportunities to overcome these economic problems through additional R & D are limited. There is some potential for special applications, and there are many technologies that could contribute to the energy supply of developing countries. In general, however, progress in energy conservation and the use of renewable energy sources will depend on the degree to which energy policy measures can improve their economic basis. For some technologies, such as solar thermal power stations and coal liquefaction, large-scale economic deployment cannot be foreseen today. Instead of establishing costly demonstration projects, emphasis will be put on improving key components of these technologies with the aim of having the most advanced technology available when the economic parameters are more favorable.

    We can summarize the IPY goals as: (a) make major advances in polar knowledge and understanding; (b) leave a legacy of new or enhanced observational systems, facilities and infrastructure; (c) excite a new generation of polar scientists and engineers, and (d) elicit exceptional interest and participation from polar residents, schoolchildren, the general public, and decision-makers, worldwide. This talk reports on the progress and prospects in each of those areas from an overall international view; separate talks will describe details of future researcher and the IPY outreach efforts. To achieve major advances in knowledge, IPY has entrained the intellectual resources of thousands of scientists, many more than expected, often from 'non- polar' nations, and representing an unprecedented breadth of scientific specialties; integration of those efforts across disciplines to achieve integrated system-level understanding remains a substantial challenge. Many national and international organizations prepare plans to sustain new and improved observational systems, but clear outcomes and the necessary resources remain elusive. International outreach networks gradually build breadth and strength, largely through IPY Polar Science Days and other internationally- coordinated IPY events. A new Association of Polar Early Career Scientists (APECS) devotes talent and energy to shaping the future of polar research. These activities and networks may, with time and with continued international coordination, achieve an exceptional level of interest and participation. In all areas, much work remains.

    2014-01-01

    Prospective memory involves the self-initiated retrieval of an intention upon an appropriate retrieval cue. Cue identification can be considered as an orienting reaction and may thus trigger a psychophysiological response. Here we present two experiments in which skin conductance responses (SCRs) elicited by prospective memory cues were compared to SCRs elicited by aversive stimuli to test whether a single prospective memory cue triggers a similar SCR as an aversive stimulus. In Experiment 2 we also assessed whether cue specificity had a differential influence on prospective memory performance and on SCRs. We found that detecting a single prospective memory cue is as likely to elicit a SCR as an aversive stimulus. Missed prospective memory cues also elicited SCRs. On a behavioural level, specific intentions led to better prospective memory performance. However, on a psychophysiological level specificity had no influence. More generally, the results indicate reliable SCRs for prospective memory cues and point to psychophysiological measures as valuable approach, which offers a new way to study one-off prospective memory tasks. Moreover, the findings are consistent with a theory that posits multiple prospective memory retrieval stages.

    So far ergonomics has been concerned with two categories of activities: correction and design. We propose to add a third category: prospection, and by so doing, we introduce a new series of activities that opens up the future of ergonomics. Corrective ergonomics relates to the past and comes with a demand and a client. It is turned towards the correction of existing situations and aims to reduce or eliminate problems. Here, after delimiting and defining the problem, the challenge is to find the best solution. Ergonomics for design relates to the present and also comes with a demand and a client. It is turned towards the design of new artefacts that have already been identified by a client, and that will allow users to do some activity and attain their goals. Here, after defining the scope of the project and the functional requirements, the challenge is to do the best design. Finally, prospective ergonomics relates to the future and does not come with a demand and a client. It is turned towards the creation of future things that have not been identified yet. Here the challenge is to detect existing user needs or anticipate future ones, and imagine solutions. These three categories of activities overlap and are not exclusive of each other. In this paper we define prospective ergonomics and compare it with corrective ergonomics and ergonomics for design. We describe its origin, goal, and prospects, we analyze its impacts on education and practice, and we emphasize the need of new collaboration between ergonomics and other disciplines.

    The impact of climate change on forests and the feedback of forests to the climate are the focus of study on global change as well as one of the important research topic in forest ecology. The impact of the global change on forests represents significant regional variation. In the arid area of the Central Asia, the mountainous forests are changing notably with the global warming, especially for the change of the alpine trimline. On the north slope of the Tianshan Mountains with clear vegetation spectrum, the climate changed significantly in the latest 50 years, which is the ideal region for researching changes of the alpine trimline. Photogrammetry and interpretation of the satellite images with high resolution are the new techniques and methods to enhance exploration of alpine trimline change in this area, which is helpful for researching the feature and process of the variations occurring near the forest upper and lower limits of the trimline.

    Full Text Available Abstract Background When measuring neighbourhood effects on health, it is both incorrect to treat individuals as if they were static and tied to their residential neighbourhood and to consider neighbourhoods rigid places whose geographical scales can be delineated a priori. We propose here to investigate the effects of residential medical density on health-seeking behaviours, taking into account the mono/polycentric structure of individual activity space (i.e., the space within which people move in the course of their daily activities and exploring various neighbourhood units based on administrative delineations and regular grids. Methods We used data collected in the SIRS cohort study, which was carried out over a 5-year period (2005–2010 among a representative population living in 50 census blocks in the Paris metropolitan area. In the 662 women who lived in the same census blocks during the follow-up period and who had reported a recent cervical screening at baseline, we studied the association between residential medical density and individual activity space and the incidence of delayed cervical screening (> 3 years in multilevel logistic regression models after adjustment for potential confounders. Results Among the 662 women studied, there were 94 instances of delayed cervical screening in 2010 (14%. The women who indicated that their activity space was concentrated within their neighbourhood of residence were significantly more at risk for an incident delayed cervical screening. No significant association was found between residential medical density and the incidence of delayed cervical screening. However, we observed a significant interaction between individual activity space and residential medical density. Indeed, women living in neighbourhoods with a low medical density had a significantly higher risk of delayed screening, but only if they reported that their daily activities were centred within their neighbourhood of residence

    Xiaoshan area is located inside the middle-west part of Xiaoqinling-Xiaoshan-Xiong’ershan-Waifang-shan Au-Ag-Mo polymetallic metallogenic belt in western Henan.However,the measured reserves of gold ores is far less than that of Xiaoqinling area and eastern Xiong’ershan area.Therefore,the prospecting po-tential in Xiaoshan area attracts great attention of related industrial sectors.Combined with previous work, this paper put forth the theory that the gold ores in the area were predominated by fracture zone alteration rock type and quartz vein type.According to the analysis of typical deposits,the paper concluded that the mineralization of gold ores could be divided into four stages from early to late:(1)quartz-pyrite (arsenopy-rite)stage,(2)pyrite-quartz stage,(3)quartz-polymetallic sulfide stage,and (4)quartz-carbonate stage. Among the four stages,stage (2)and (3)are the main stages of mineralization.The author conducted analy-sis on the content,homogenization temperature and S-H-O-Pb isotope composition of the fluid inclusions in the quartz crystals in each ore-forming stage.It indicates that the fluid was CO 2-rich aqueous fluid with nu-merous dissolved Na+ and Ca2 + ions.The homogenization temperature of fluid inclusions ranges from 243℃to 285℃,and it suggests that the gold deposits in Xiaoshan area are mainly intermediate temperate hydro-thermal deposits being short of fluid inclusions of high temperature stage.The δ34 S value of metal sulfide ranges from -0.5‰ to 5.4‰ and it shows the characteristics of deep source sulfur.And its δ1 8 O H2 O value ranges from 0.1‰ to 9.4‰ and δ1 8 D value ranges from - 134.9‰ to 24.3‰,and it shows that the ore-forming fluid occurs mainly as magmatic water with lesser atmospheric precipitation and metamorphic water. Based on the comparison between outcrop area of granitic intrusive rocks in Xiaoshan area and that in Xiao-qinling area,it appears that the unsatisfactory prospecting results in Xiaoshan area

  6. Prospecting for lunar resources

    Science.gov (United States)

    Taylor, G.; Martel, L.

    Large space settlements on the Moon (thousands of people) will require use of indigenous resources to build and maintain the infrastructure and generate products for export. Prospecting for these resources is a crucial step in human migration to space and needs to begin before settlement and the establishment of industrial complexes. We are devising a multi-faceted approach to prospect for resources. A central part of this work is developing the methodology for prospecting the Moon and other planetary bodies. This involves a number of investigations: (1) It is essential to analyze the economics of planetary ore deposits. Ore deposits are planetary materials that we can mine, process, and deliver to customers at a profit. The planetary context tosses in some interesting twists to this definition. (2) We are also making a comprehensive theoretical assessment of potential lunar ore deposits. Our understanding of the compositions, geological histories, and geological processes on the Moon will lead to significant differences in how we assess wh a t types of ores could be present. For example, the bone-dry nature of the Moon (except at the poles) eliminates all ore deposits associated with hydrothermal fluids. (3) We intend to search for resources using existing data for the Moon. Thus, prospecting can begin immediately. We have a wealth of remote sensing data for the Moon. We also have a good sampling of the Moon by the Apollo and Luna missions, and from lunar meteorites. We can target specific types of deposits already identified (e.g. lunar pyroclastic deposits) and look for other geological settings that might have produced ores and other materials of economic value. Another approach we will take is to examine all data available to look for anomalies. Examples are unusual spectral properties, large disagreements between independent techniques that measure the same property, unusual elemental ratios, or simply exceptional properties such as elemental abundances much

  9. Prospecting for coal in China with remote sensing

    With the rapid development of China's economy, coal resources are increasingly in great demand. As a result, the remaining coal reserves diminish gradually with large-scale exploitation of coal resources. Easily-found mines which used to be identiffed from outcrops or were buried under shallow overburden are decreasing, especially in the prosperous eastern regions of China,which experience coal shortages. Currently the main targets of coal prospecting are concealed and unidentified underground coal bodies, making it more and more difficult for coal prospecting. It is therefore important to explore coal prospecting by taking advantage of modern remote sensing and geographic information system technologies. Given a theoretical basis for coal prospecting by remote sensing, we demonstrate the methodologies and existing problems systematically by summarizing past practices of coal prospecting with remote sensing. We propose a new theory of coal prospecting with remote sensing. In uncovered areas, coal resources can be prospected for by direct interpretation. In coal beating strata of developed areas covered by thin Quaternary strata or vegetation, prospecting for coal can be carried out by indirect interpretation of geomorphology and vegetation. For deeply buried underground deposits, coal prospecting can rely on tectonic structures, interpretation and analysis of new tectonic clues and regularity of coal formation and preservation controlled by tectonic structures. By applying newly hyper-spectral, multi-polarization, multi-angle, multi-temporal and multi-resolution remote sensing data and carrying out integrated analysis of geographic attributes,ground attributes, geophysical exploration results, geochemical exploration results, geological drilling results and remote sensing data by GIS tools, coal geology resources and mineralogical regularities can be explored and coal resource information can be acquired with some confidence.

    In the age of asteroid mining the ability to find promising ore-bearing bodies will be valuable. This will give rise to a new discipline- "Applied Astronomy". Just as most geologists work in industry, not in academia, the same will be true of astronomers. Just how rare or common ore-rich asteroids are likely to be, and the skills needed to assay their value, are discussed here, with an emphasis on remote - telescopic - methods. Also considered are the resources needed to conduct extensive surveys of asteroids for prospecting purposes, and the cost and timescale involved. The longer-term need for applied astronomers is also covered.

    1988-07-01

    The impact of economic and technological trends upon the level and structure of labor demand is examined, exploring the methods used to model the labor market and making special reference to demography and technology. Evidence on recent and prospective changes in labor demand is reviewed for France, Germany, Italy, the Netherlands, and the UK. The models used to explore future employment scenarios usually fail to incorporate the linkages required to fully analyze the various demographic-economic interactions. Further, this is not generally viewed as a limitation, given the time frame of most employment projections and their preoccupation with changes in the structure of labor demand. Medium-term multisectoral models tend to pay more attention to both demographic and technical change, but the treatment of both aspects is limited. The projections provide a framework for considering how both socioeconomic behavior and policy might change to achieve different outcomes. The greater a model's behavioral content, as expressed in its relationships between different variables, the greater the insight obtainable from simulation exercises. The 1st half of the 1970s was characterized by a reduction in German employment, representing the severest of European reactions to the oil crisis. The 2nd half of the decade recorded rapid growth in Italy and the Netherlands. The 1980s started with marked declines in Germany and the UK. Overall, the net gains of the 1970s were lost in the recession following the 2nd oil crisis. In none of the 5 countries studied does any realistic prospect emerge of achieving full employment before 2000. The most optimistic outcome is that unemployment will decline only slowly, it at all. The growth of both new forms and areas of employment will not compensate sufficiently for the loss of jobs elsewhere and the growth of labor supply. The industrial sector will continue to experience change in favor of the service sector but at a slower rate than during

    The monograph by A.I.Kiselev, A.A. Medvedev and Y.A.Menshikov, Astronautics: Summary and Prospects, aroused enthusiasm both among experts and the public at large. This is due to the felicitous choice of presentation that combines a simple description of complex space matters with scientificsubstantiation of the sub­ jectmatter described. The wealth of color photos makes the book still more attractive, and it was nominated for an award at the 14th International Moscow Book Fair, being singled out as the "best publication of the book fair". The book's popularity led to a second edition, substantially revised and enlarged. Since the first edition did not sufficiently cover the issues of space impact on ecology and the prospective development of space systems, the authors revised the entire volume, including in it the chapter "Space activity and ecology" and the section "Multi-function space systems". Using the federal monitoring system, now in the phase of system engi­ neering, as an example, the authors consi...

    Prospects for North American tidal power electrical generation are reviewed. Studies by the US Army Corps of Engineers of 90 possible generation schemes in Cobscook Bay, ME, indicated that maximum power generation rather than dependable capacity was the most economic method. Construction cost estimates for 15 MW bulb units in a single effect mode from basin to the sea are provided; five projects were considered ranging from 110-160 MW. Additional tidal power installations are examined for: Half-Moon Cove, ME (12 MW, 18 ft tide); Cook Inlet, AK, which is shown to pose severe environmental and engineering problems due to fish migration, earthquake hazards, and 300 ft deep silt deposits; and the Bay of Fundy, Canada. This last has a 17.8 MW plant under construction in a 29 ft maximum tide area. Other tidal projects of the Maritime Provinces are reviewed, and it is noted that previous economic evaluations based on an oil price of $16/barrel are in need of revision.

Main coal seams have features of shallow buried depth, multiple seams, developed minor structures, thus conventional coalfield seismic acquisition method can only acquire low signal-noise ratio and low resolution, hardly to reach seismic prospecting "3 High" (high signal-noise ratio, resolution and fidelity) requirement. In allusion to Wangjialing area actual characteristics, on the basis of careful survey of near-surface loess velocity layering structure, using integrated key acquisition techniques of well depth roll-along design, source/geophone associated combination, low frequency geophone receiving, large offset/wide coverage field setup, effectively improved seismic data signal-noise ratio and resolution, obtained good continuity reflection of lower coal group, thus laid a foundation for delicate structure identifying and lithologic study.

    2017-01-01

    After the successful operation at the centre-of-mass energies of 7 and 8 TeV in 2010-2012, the LHC was ramped up and successfully took data at the centre-of-mass energies of 13 TeV in 2015 and 2016. Meanwhile, plans are actively advancing for a series of upgrades of the accelerator, culminating roughly ten years from now in the high-luminosity LHC (HL-LHC) project, which will deliver of the order of five times the LHC nominal instantaneous luminosity along with luminosity levelling. The ultimate goal is to extend the dataset from about few hundred fb ‑1 expected for LHC running by the end of 2018 to 3000 fb ‑1 by around 2035 for ATLAS and CMS. The challenge of coping with the HL-LHC instantaneous and integrated luminosity, along with the associated radiation levels, requires further major changes to the ATLAS detector. The designs are developing rapidly for a new all-silicon tracker, significant upgrades of the calorimeter and muon systems, as well as improved triggers and data acquisition. ATLAS is also examining potential benefits of extensions to larger pseudorapidity, particularly in tracking and muon systems. This report summarizes various improvements to the ATLAS detector required to cope with the anticipated evolution of the LHC luminosity during this decade and the next. A brief overview is also given on physics prospects with a pp centre-of-mass energy of 14 TeV.

    ANAIS experiment will look for dark matter annual modulation with large mass of ultra-pure NaI(Tl) scintillators at the Canfranc Underground Laboratory (LSC), aiming to confirm the DAMA/LIBRA positive signal in a model-independent way. Two 12.5 kg each NaI(Tl) crystals provided by Alpha Spectra are currently taking data at the LSC. Present status of ANAIS detectors background and general performance is summarized; in particular, thanks to the high light collection efficiency prospects of lowering the threshold down to 1 keVee are reachable. Crystal radiopurity goals are fulfilled for $^{232}$Th and $^{238}$U chains and $^{40}$K activity, although higher than original goal, could be accepted; however, high $^{210}$Pb contamination out-of-equilibrium has been identified. More radiopure detectors are being built by Alpha Spectra. The ongoing high quantum efficiency PMT tests and muon veto characterization are also presented. Finally, the sensitivity of the experiment for the annual modulation in the WIMP signal,...

    Geologic, geochemical, and geophysical studies together with a review of historic mining and prospecting activities indicate that the Cactus Spring Roadless Area in California has little promise for the occurrence of mineral or energy resources. Marble bodies occur in the northern part of the roadless area and are possible resources for building stone, crushed and quarried aggregate, and lime and magnesium for Portland cement and industrial applications. It is recommended that the terrane of marble be mapped and sampled carefully in order to evaluate the quantity and quality of the carbonate resources.

    Pingran area is located in the Ma Jiang-Xam Nua island arc metallogenic belt, and the metallogenic condition of magmatic copper-nickel sulfide deposits is excellent. 1 ∶ 50 000 stream sediment survey around the Pingran area of Laos revealed an anomaly combination of multiple elements dominated by Cu, Ni and Co accompanied by Cr, V and Ti, reflecting the metallogenic specialization of the basic-ultrabasic rocks. The authors used the method of factor analysis and clustering to analyze the data of 1:50000 stream sedi-ment survey in Pingran area,and made a geological interpretation of the deposit. It is suggested that the anomalies from the geochemical survey are associated with the mineralization along a series of NW-trending fracture zones and the basic-ultrabasic rocks. Cluster analy-sis of the stream sediment geochemical data of Pingran area shows that fifteen kinds of trace elements can be grouped into three types, i.e. Ni, Cr, Cu, V, Co, Zn and Ti belong to the first type,As, Sb and Pb to the second type,and the rest to the third type. The first type reflects elemental distribution, accumulation characteristics and related mineralization information of mafic-ultramafic rocks, whereas the second type reflects the combination of ore-forming elements at low-medium temperature. The primary factor of stream sedi-ment geochemical element F1 may represent Cu, Ni and Co mineralization of mafic-ultramafic rocks. There are 607 samples with the factor F1 scores higher than 2 among all the 3806 samples from Pingran area. Distribution characteristics of the factor F1 score anoma-lies are roughly consistent with those of Au,As and Cu anomalies in Pingran area. Thus,the overlapped portion between the Cu, Ni and Co anomaly area and the area where factor F1 scores are higher than 2 should be the key ore-prospecting target dominated by Cu, Ni and Co.%1∶5万水系沉积物测量显示,平然地区矿化异常是一个以Cu、Ni、Co异常为主,伴随有Cr、V、Ti等的

    Jojoba (Simmondsia chinensis) is a crop that might be cultivated profitably in the arid and semi-arid zones of certain cultivated profitably in the arid and semi-arid zones of certain developing countries. This report assesses the present state of research on the crop and gives an opinion as to its prospects of being of economic benefit to these areas. The report is divided into five sections. In Section 1 the plant and its natural habitats are described and current research and the problems to be overcome in cultivating the crop are outlined. In Section 2 the chemistry of jojoba and other waxes is discussed. In Section 3 consideration is given to the end-use potential of jojoba and an attempt is made to forecast the future market demand and price for jojoba oil, both as a liquid and as a solid wax. In Section 4 the economics of jojoba production are discussed in light of the findings in the earlier sections. Finally, in Section 5, the wider aspects of plant introductions are considered briefly and conclusions drawn regarding jojoba's potential and its future research needs. It will be essential to increase jojoba yield significantly before cultivation will be viable except on a small scale. A satisfactory mechanized harvesting system also needs to be developed. The market for jojoba oil at various levels of production is estimated at production of less than 1000 tons (pounds-sterling 5500- pounds-sterling 7700 per ton); production of 2000 to 5000 tons (pounds-sterling 900- pounds-sterling 950 per ton); and production up to 20,000 tons (pounds-sterling 500-pounds-sterling 600 per ton).

    Distinct functional pathways for processing words and numbers have been hypothesized from the observation of dissociated impairments of these categories in brain-damaged patients. We aimed to identify the cortical areas involved in Arabic number reading process in patients operated on for various brain lesions. Direct cortical electrostimulation was prospectively used in 60 brain mappings. We used object naming and two reading tasks: alphabetic script (sentences and number words) and Arabic number reading. Cortical areas involved in Arabic number reading were identified according to location, type of interference, and distinctness from areas associated with other language tasks. Arabic number reading was sustained by small cortical areas, often extremely well localized (area (Brodmann area 45), the anterior part of the dominant supramarginal gyrus (Brodmann area 40; p area (Brodmann area 37; p areas.

    Luis Barba Laboratorio de Prospección Arqueológica Instituto de Investigaciones Antropológicas Universidad Nacional Autonoma de México The first magnetic survey in archaeological prospection was published in 1958 in the first number of Archaeometry, in Oxford. That article marked the beginning of this applications to archaeology. After that, magnetic field measurements have become one of the most important and popular prospection tools. Its most outstanding characteristic is the speed of survey that allows to cover large areas in short time. As a consequence, it is usually the first approach to study a buried archaeological site. The first attempts in Mexico were carried out in 196. Castillo and Urrutia, among other geophysical techniques, used a magnetometer to study the northern part of the main plaza, zocalo, in Mexico City to locate some stone Aztec sculptures. About the same time Morrison et al. in La Venta pyramid used a magnetometer to measure total magnetic field trying to find a substructure. Some years later Brainer and Coe made a magnetic survey to locate large stone Olmec heads in San Lorenzo Tenochtitlan, Veracruz. Technology development has provided everyday more portable and accurate instruments to measure the magnetic field. The first total magnetic field proton magnetometers were followed by differential magnetometers and more recently gradiometers. Presently, multiple sensor magnetometers are widely used in European archaeology. The trend has been to remove the environmental and modern interference and to make more sensitive the instruments to the superficial anomalies related to most of the archaeological sites. There is a close relationship between the geology of the region and the way magnetometry works in archaeological sites. Archaeological prospection in Europe usually needs very sensitive instruments to detect slight magnetic contrast of ditches in old sediments. In contrast, volcanic conditions in Mexico produce large magnetic contrast

    Full Text Available This article defines a new term, Effective Area, K, of a given territory as a function of four independent parameters: its nominal acreage, A, the intellectual competence of its inhabitants, B, their social competence, C, and their global influence, D, using a simple formalism: K = A x B x C x D. This analysis demonstrates that in our current world any consideration of the physical area of a given territory is meaningless if the quality of its population is ignored. K is a much more useful parameter than A, certainly for political and economical considerations, explaining why claims for territorial expansion are placed low on the national ladder of priorities in the developed countries. In many respects, large geographical areas may become a burden rather than an advantage. Thus, the importance of armed conflicts over geographical territories, which have taken a dominant part of the entire human history, is fading away. Furthermore, although the global acreage is constant, the total effective area of planet Earth keeps growing, providing sufficient room for the growing human population.

    Full Text Available Caries remains the most prevalent non-contagious infectious disease in humans. It is clear that the current approaches to decrease the prevalence of caries in human populations, including water fluoridation and school-based programs, are not enough to protect everyone. The scientific community has suggested the need for innovative work in a number of areas in cariology, encompassing disease etiology, epidemiology, definition, prevention, and treatment. We have pioneered the work on genetic studies to identify genes and genetic markers of diagnostic, prognostic, and therapeutic value. This paper summarizes a presentation that elaborated on these initial findings.

    The Soviet Union produces 20% of world energy but since 1988 this is in decline. Awakening consumerism and a sea-change in the structure of foreign trade and internal investment are placing this key industry into unprecedented uncertainty. The difference between success and failure goes beyond the 1988 peak of six million barrels daily of exports in oil equivalent. The article quantifies the key areas of energy uncertainty as equal in volume to total OPEC output and sees the long-term changes of success more than ever dependent on coordinated planning and investment as well as on market reality.

    In this Geothermal Play Fairways Analysis project we sought to develop new ways to analyze geologic, geochemical, and geophysical data to reduce the risk and increase the prospects of successful geothermal exploration and development. We collected, organized, and analyzed data from southwest New Mexico in the context of an integrated framework that combines the data for various signatures of a geothermal resource into a cohesive analysis of the presence of heat, fluid, and permeability. We incorporated data on structural characteristics (earthquakes, geophysical logs, fault location and age, basement depth), topographic and water table elevations, conservative ion concentrations, and thermal information (heat flow, bottom hole temperature, discharge temperature, and basement heat generation). These data were combined to create maps that indicate structural analysis, slope, geothermometry, and heat. We also mapped discharge areas (to constrain elevations where groundwater may be discharged through modern thermal springs or paleo-thermal springs) and subcrops: possible erosionally- or structurally-controlled breaches in regional-scale aquitards that form the basis of our hydrogeologic windows concept. These two maps were particularly useful in identifying known geothermal systems and narrowing the search for unknown geothermal prospects. We further refined the "prospectivity" of the areas within the subcrops and discharge areas by developing and applying a new method for spatial association analysis to data on known and inferred faults, earthquakes, geochemical thermometers, and heat flow. This new methodology determines the relationships of the location and magnitudes of observations of these data with known geothermal sites. The results of each of the six spatial association analyses were weighted between 0 and 1 and summed to produce a prospectivity score between 0 and 6, with 6 indicating highest geothermal potential. The mean value of prospectivity for all

    2012-07-01

    Clay-based buffer and tunnel backfill materials are important barriers in the KBS- 3 repository concept for final disposal of spent nuclear fuel in Finland. Significant changes can be expected to occur to the properties and behaviour of buffer and backfill, especially during re-saturation and through the thermal period. Reactions will occur in response to thermal and chemical gradients, induced by the thermal output of the spent fuel and at interfaces between different barrier materials, such as cement/clay, steel/clay etc. Processes of ion exchange, mineral dissolution and precipitation, and swelling can lead to significant re-distribution of mass and evolution of physical properties so that reliable predictive modelling of future behaviour and properties must be made. This report evaluates the current status of modelling of buffer and backfill evolution and tries to assess the potential future capabilities in the short- to medium-term (5-10 years) in a number of technical areas: (1) Non-isothermal (T-H-M-C-B) modelling and the potential for cementation, (2) The consistency of models, (3) Swelling pressure, (4) Cement-bentonite interactions, (5) Iron-bentonite interactions, (6) Mechanical (shear) behavior, and (7) Bentonite erosion.

Possibility of success estimation, assuming discovery of hydrocarbons and the potential recoverable quantities range under a commercial development program are the basis of Prospect evaluation activities. The objective was to find the new shallow prospects in reservoir sandstone of I -Formation in Malay basin. The prospects in the study area are mostly consisting of faulted structures and stratigraphic channels. The methodology follows seismic interpretation and mapping, attribute analysis, evaluation of nearby well data i.e., based on well - log correlation. The petrophysical parameters analogue to nearby wells was used as an input parameter for volumetric assessment. Based on analysis of presence and effectiveness, the prospect has a complete petroleum system. Two wells have been proposed to be drilled near the major fault and stratigraphic channel in I-35 reservoir that is O-1 and O-2 prospects respectively. The probability of geological success of prospect O-1 is at 35% while for O-2 is 24%. Finally, for hydrocarbon in place volumes were calculated which concluded the best estimate volume for oil in O-1 prospect is 4.99 MMSTB and O-2 prospect is 28.70 MMSTB while for gas is 29.27 BSCF and 25.59 BSCF respectively.

  8. Lunar Prospecting With Chandra

    Science.gov (United States)

    2003-09-01

    Observations of the bright side of the Moon with NASA's Chandra X-ray Observatory have detected oxygen, magnesium, aluminum and silicon over a large area of the lunar surface. The abundance and distribution of those elements will help to determine how the Moon was formed. "We see X-rays from these elements directly, independent of assumptions about the mineralogy and other complications," said Jeremy Drake of the Harvard-Smithsonian Center for Astrophysics in Cambridge, Mass., at a press conference at the "Four Years with Chandra" symposium in Huntsville, Alabama. "We have Moon samples from the six widely-space Apollo landing sites, but remote sensing with Chandra can cover a much wider area," continued Drake. "It's the next best thing to being there, and it's very fast and cost-effective." The lunar X-rays are caused by fluorescence, a process similar to the way that light is produced in fluorescent lamps. Solar X-rays bombard the surface of the Moon, knock electrons out of the inner parts of the atoms, putting them in a highly unstable state. Almost immediately, other electrons rush to fill the gaps, and in the process convert their energy into the fluorescent X-rays seen by Chandra. According to the currently popular "giant impact" theory for the formation of the Moon, a body about the size of Mars collided with the Earth about 4.5 billion years ago. This impact flung molten debris from the mantle of both the Earth and the impactor into orbit around the Earth. Over the course of tens of millions of years, the debris stuck together to form the Moon. By measuring the amounts of aluminum and other elements over a wide area of the Moon and comparing them to the Earth's mantle, Drake and his colleagues plan to help test the giant impact hypothesis. "One early result," quipped Drake, "is that there is no evidence for large amounts of calcium, so cheese is not a major constituent of the Moon."

    This article provides a critical discussion of prospects of solar thermal hydrogen production in terms of technological and economic potentials and their possible role for a future hydrogen supply. The study focuses on solar driven steam methane reforming, thermochemical cycles, high temperature water electrolysis and solar methane cracking. Development status and technological challenges of the processes and objectives of ongoing research are described. Estimated hydrogen production costs are shown in comparison to other options. A summary of current discussions and today's scenarios of future use of hydrogen as an energy carrier and a brief overview on the development status of end-use technologies characterise uncertainties whether hydrogen could emerge as important energy carrier until 2050. Another focus is on industrial hydrogen demand in areas with high direct solar radiation which may be the main driver for the further development of solar thermal hydrogen production processes in the coming decades.

    Studies of steroid modifications catalyzed by microbial whole cells represent a well-established research area in white biotechnology. Still, advances over the last decade in genetic and metabolic engineering, whole-cell biocatalysis in non-conventional media, and process monitoring raised research in this field to a new level. This review summarizes the data on microbial steroid conversion obtained since 2003. The key reactions of structural steroid functionalization by microorganisms are highlighted including sterol side-chain degradation, hydroxylation at various positions of the steroid core, and redox reactions. We also describe methods for enhancement of bioprocess productivity, selectivity of target reactions, and application of microbial transformations for production of valuable pharmaceutical ingredients and precursors. Challenges and prospects of whole-cell biocatalysis applications in steroid industry are discussed.

    intrusion was analyzed.The results show that these Yanshanian intrusive rocks have geochemical characteristics similar to those of adakite,with features of SiO2 >56% ,high Al content (Al2O3≥ 15% ) ,rich in Sr,Ba and Cr,Ni,high inSr/Y(145-181) and (La/Yb)NS≥21 ratios; with low Y(7.5 ~9.1 μg/g) and Yb (0.68-0.71 μg/g) contents,and no significant Eu anomalies (8Eu =0.96-1.04).The high MgO contents (3.15% -3.36%),Mg(56~66) and Sr/La(56 ~67) ,display characteristics of seawater alteration of MORB.The Yanshanian magmatic rocks in this region are the typical adakites which were derived from subducted oceanic crust,During the emplacement of the rocks,the ore-forming materials were enriched and mineralized in the suitable position.The Shangyaopu magmatic intrusion nearby has similar geochemical features,and thus,should have similar genetic and mineralization background like that of the Chuxian intrusion.Moreover,we found a pulse of silicified shattered dolomite belt with micron pyrite on the north-west side of the Chouxian magmatic body occurring as siliceous vein and polymetallic mineralization around the Shangyaopu magmatic body.Comparing the silicified belt and siliceous vein to the Langyashan copper mineralization skarn,we deduced that they are closely related to the Yanshanian intrusive rocks,the Shangyaopu magmatic body and surrounding areas can be prospective area for copper associated with gold deposit.In conclusion,the authors propose that regional ore exploration should not be limited to the present skarn-type copper-gold deposit while the new type of siliceous veins with polymetallic mineralization be ignored.

    One item on the agenda of future colliders is certain to be the Higgs boson. What is it trying to tell us? The primary objective of any future collider must surely be to identify physics beyond the Standard Model, and supersymmetry is one of the most studied options. it Is supersymmetry waiting for us and, if so, can LHC Run 2 find it? The big surprise from the initial 13-TeV LHC data has been the appearance of a possible signal for a new boson X with a mass ~750 GeV. What are the prospects for future colliders if the X(750) exists? One of the most intriguing possibilities in electroweak physics would be the discovery of non-perturbative phenomena. What are the prospects for observing sphalerons at the LHC or a future collider?

    Research by Raz and his associates has repeatedly found that suggestions for hypnotic agnosia, administered to highly hypnotizable subjects, reduce or even eliminate Stroop interference. The present paper sought unsuccessfully to extend these findings to negative priming in the Stroop task. Nevertheless, the reduction of Stroop interference has broad theoretical implications, both for our understanding of automaticity and for the prospect of de-automatizing cognition in meditation and other altered states of consciousness.

    Most research to date on the role of maltreatment experiences in depression has focused on physical and sexual maltreatment. However, several researchers have theorized that emotional maltreatment may be more strongly linked to depression. Furthermore, prospective studies in this area are lacking. This study addressed these issues by examining whether experiences of current emotional maltreatment predicted the development of new prospective episodes of major (MD) or minor depression (MiD), and the subtype of hopelessness depression (HD) in young adults. It also assessed whether current emotional maltreatment from peers and from authority figures separately predicted the occurrence of depressive episodes. One hundred and sixty-five participants from the Cognitive Vulnerability to Depression Project were followed prospectively for 2.5 years. Current emotional maltreatment and new depressive episodes were assessed with life event and diagnostic interviews administered every 6 weeks. Greater overall emotional maltreatment predicted shorter time to onset of new MD, MiD, and HD episodes. Peer- and authority-perpetrated emotional maltreatment separately predicted shorter time to development of new HD episodes. Greater emotional maltreatment in young adults prospectively predicts onset of depression, particularly HD. These findings highlight the importance of adult emotional maltreatment experiences in determining targets for prevention and treatment. (c) 2009 Wiley-Liss, Inc.

    Background This article presents an overview of the concept of social capital, reviews prospective multilevel analytic studies of the association between social capital and health, and discusses intervention strategies that enhance social capital. Methods We conducted a systematic search of published peer-reviewed literature on the PubMed database and categorized studies according to health outcome. Results We identified 13 articles that satisfied the inclusion criteria for the review. In general, both individual social capital and area/workplace social capital had positive effects on health outcomes, regardless of study design, setting, follow-up period, or type of health outcome. Prospective studies that used a multilevel approach were mainly conducted in Western countries. Although we identified some cross-sectional multilevel studies that were conducted in Asian countries, including Japan, no prospective studies have been conducted in Asia. Conclusions Prospective evidence from multilevel analytic studies of the effect of social capital on health is very limited at present. If epidemiologic findings on the association between social capital and health are to be put to practical use, we must gather additional evidence and explore the feasibility of interventions that build social capital as a means of promoting health.

    In 2006, the United States Geological Survey (USGS) completed a detailed analysis and interpretation of available 2-D and 3-D seismic data, along with seismic modeling and correlation with specially processed downhole well log data for identifying potential gas hydrate accumulations on the North Slope of Alaska. A methodology was developed for identifying sub-permafrost gas hydrate prospects within the gas hydrate stability zone in the Milne Point area. The study revealed a total of 14 gas hydrate prospects in this area.In order to validate the gas hydrate prospecting protocol of the USGS and to acquire critical reservoir data needed to develop a longer-term production testing program, a stratigraphic test well was drilled at the Mount Elbert prospect in the Milne Point area in early 2007. The drilling confirmed the presence of two prominent gas-hydrate-bearing units in the Mount Elbert prospect, and high quality well logs and core data were acquired. The post-drill results indicate pre-drill predictions of the reservoir thickness and the gas-hydrate saturations based on seismic and existing well data were 90% accurate for the upper unit (hydrate unit D) and 70% accurate for the lower unit (hydrate unit C), confirming the validity of the USGS approach to gas hydrate prospecting. The Mount Elbert prospect is the first gas hydrate accumulation on the North Slope of Alaska identified primarily on the basis of seismic attribute analysis and specially processed downhole log data. Post-drill well log data enabled a better constraint of the elastic model and the development of an improved approach to the gas hydrate prospecting using seismic attributes. ?? 2009.

    To examine the prospective, reciprocal association between sleep deprivation and depression among adolescents. A community-based two-wave cohort study. A metropolitan area with a population of over 4 million. 4,175 youths 11-17 at baseline, and 3,134 of these followed up a year later. Depression is measured using both symptoms of depression and DSM-IV major depression. Sleep deprivation is defined as ≤ 6 h of sleep per night. Sleep deprivation at baseline predicted both measures of depression at follow-up, controlling for depression at baseline. Examining the reciprocal association, major depression at baseline, but not symptoms predicted sleep deprivation at follow-up. These results are the first to document reciprocal effects for major depression and sleep deprivation among adolescents using prospective data. The data suggest reduced quantity of sleep increases risk for major depression, which in turn increases risk for decreased sleep.

    The Suwar Cu-Ni sulphide prospect is very highly regarded for its potential to host a major nickel-copper sulphide deposit in Republic of Yemen, a mineral resource lacking country. The ore-hosting intrusion is a lopolith about 6km long and lkm wide and more than 300m deep. There are two types of Cu-Ni mineralizations in the prospect: primary massive chalcopyrite+ pyrrhotite+ pentlandite controlled by gravitational and structural traps while the secondary Cu-Ni mineralization is coarse grained and occur as veins, veinlets, fracture fill, blebs or associated with coarse, re-crystallized carbonate in shear zones and faults. The deposit type of the prospect is believed to be the one associated with the ultramafic component of a large, broadly differentiated noritic, gabbroid intrusive. It is suggested that the prospect and adjacent area possibly contain a similar world class Ni-Cu deposits as that in Jinchuan, China.

    Important applications for x- and ..gamma..-ray spectroscopy are found in prospecting, materials characterization, environmental monitoring, the life sciences, and nuclear physics. The specific requirements vary for each application with varying degrees of emphasis on either spectrometer resolution, detection efficiency, or both. Since no one spectrometer is ideally suited to this wide range of needs, compromises are usually required. Gas and scintillation spectrometers have reached a level of maturity, and recent interest has concentrated on semiconductor spectrometers. Germanium detectors are showing continuing refinement and are the spectrometers of choice for high resolution applications. The new high-Z semiconductors, such as CdTe and HgI/sub 2/, have shown steady improvement but are limited in both resolution and size and will likely be used only in applications which require their unique properties.

    Full Text Available En los cuerpos máficos-ultramáficos del área de Virorco y La Bolsa, bloque central de la sierra de San Luis, se han detectado sulfuros polimetálicos en venillas y diseminados. Como herramienta de prospección geofísica se utilizó el método de autopotencial en combinación con estudios geomagnéticos. Los lentes máfico-ultramáficos están enmarcados por una caja gnéisicamigmatítica de alto grado. Una foliación milonítica de rumbo NNE y buzamiento de alto ángulo al ESE, afecta al basamento y también a los bordes de los cuerpos máfico-ultramáficos. Hacia el interior de estos últimos, alternan sectores que preservan las texturas granulares ígneas y una foliación buzante al oeste, con fajas de cizalla con foliación milonítica buzante al ESE. El estudio geofísico en Virorco indica una correspondencia entre los valores de autopotencial negativos (-150 mV y los máximos de magnetismo terrestre (+350 nT. En la zona de La Bolsa se realizaron dos perfiles de autopotencial, los cuales muestran un núcleo de autopotencial negativo de entre -40 y -55 mV, ligeramente alargado y buzante al ESE. Sobre el margen oriental, un valor de -90 mV constituye el núcleo de una anomalía alargada y también buzante al ESE. La disposición espacial de estas anomalías es coincidente con la orientación de la foliación milonítica. La correspondencia establecida con esta nueva herramienta de prospección, sustenta la removilización y concentración de los sulfuros primarios diseminados durante el evento de milonitización, ya planteada previamente en base a otras técnicas de estudio.In the Virorco and La Bolsa mafic-ultramafic bodies, central block of the Sierra de San Luis, polymetallic sulfides occur in veinlets and disseminated.

    西藏山南明则矿区斑岩型钼矿床主要由一厚大隐伏的钼矿体组成,其上部覆盖着巨厚层的古近系罗布莎群磨拉石建造.矿床赋存于冈底斯-念青唐古拉板片与喜马拉雅板片的结合带附近,赋矿岩石为钾长花岗岩和二长花岗斑岩.自上而下递次出现青盘岩化、泥化、(黄铁)绢云母化或石英钾化带.岩体侵入时代为古近纪渐新世.辉钼矿Re-Os同位素等时线年龄值为30Ma.该矿的发现为冈底斯成矿带南缘寻找同类斑岩型钼(铜)矿提供了新的线索.%The Mingze porphyry molybdenum deposit in Shannan, Tibet, is mainly composed of concealed massive molybdenum orebodies, which are covered by thick Paleogene Luobusa molasse. It lies in the suture zone between the Gangdise - Nyainqentanglha plate and the Himalayan plate. The deposit is hosted in K-feldspar granite and monzonitic granite-porphyry. From the top to the bottom of the orebody, alteration varies from propylitic alteration, argillization, phyllite-like alteration, pyritization to silicifiration and potassic alteration. The age of intrusive rock is Paleogene Oligocene, and the Re-Os isotope age of molybdenite ore is 30Ma. The discovery of the Mingze deposit provides new helpful evidence for prospecting similar porphyry molybdenum (copper) deposit along the southern margin of the Gangdise metallogenic belt.

    The article postulates the actuality of developing the concept of the psychological aspects of institution management as projected into health care area where the medical personnel is working in the conditions of higher responsibility, emotional and intellectual overloads under permanent nervous psychological stress. This contingent of medical institutions stuff very often ignore the positive psychological interventions both due to the poor labor management and the corresponding knowledge lacking. The topicality of this research vector is determined by the deficiency of the human resources' management studies in the public health field. The need in searching the investigation prospective directions is ascertained by the unexploredness of personnel management in national health care.

    The purpose of this study is to know the incidence rate of medication reconciliation at admission and discharge in patients of La Rioja and to improve the patient safety on medication reconciliation. An observational prospective study, part of the Joint Action PaSQ, Work Package 5, European Union Network for Patient Safety and Quality of Care. The study has taken into account the definitions of the Institute for Safe Medication Practices. Any unintended discrepancy in medication between chronic treatment and the treatment prescribed in the hospital was considered as a reconciliation error. A total of 750 patients were included, 9 (1.2%) of whom showed at least one discrepancy. The patients had a total of 3,156 mediations registered: 2,313 prescriptions (73.4%) showed no differences, while 821 prescriptions (26%) were intended discrepancies and 21 prescriptions (0.6%) unintended discrepancies were considered by the physician as reconciliation errors. A percentage of 1.2 of the patients, which represents 0.6% of the medicines (one in 166 medications registered) had reconciliation errors during their hospital stay. A proceeding has been implemented by means of the physician doing the medication reconciliation and reviewing it with the help of a medication reconciliation form. The medication reconciliation is a priority strategic objective to improve the safety of patients. Copyright © 2016 SECA. Published by Elsevier Espana. All rights reserved.

  4. Dual pathways to prospective remembering

    2015-01-01

    According to the multiprocess framework (McDaniel and Einstein, 2000), the cognitive system can support prospective memory (PM) retrieval through two general pathways. One pathway depends on top–down attentional control processes that maintain activation of the intention and/or monitor the environment for the triggering or target cues that indicate that the intention should be executed. A second pathway depends on (bottom–up) spontaneous retrieval processes, processes that are often triggered by a PM target cue; critically, spontaneous retrieval is assumed not to require monitoring or active maintenance of the intention. Given demand characteristics associated with experimental settings, however, participants are often inclined to monitor, thereby potentially masking discovery of bottom–up spontaneous retrieval processes. In this article, we discuss parameters of laboratory PM paradigms to discourage monitoring and review recent behavioral evidence from such paradigms that implicate spontaneous retrieval in PM. We then re-examine the neuro-imaging evidence from the lens of the multiprocess framework and suggest some critical modifications to existing neuro-cognitive interpretations of the neuro-imaging results. These modifications illuminate possible directions and refinements for further neuro-imaging investigations of PM. PMID:26236213

    1984-07-01

    The initial results of a prospective evaluation of myopic keratomileusis are reported. The procedure was attempted on 42 eyes, with an average follow-up of 10 months. The average reductions of myopia were 7.05 D and 11.59 D when measured by keratometry and refraction, respectively. Regular astigmatism increased by 0.50 D on keratometry, but there was no change in the refractive cylinder. The majority of patients had some irregular astigmatism on corneoscopy. The average percent correction, based on refraction, was 94.1 +/- 24%, and the correlation coefficient was 0.43. Visual rehabilitation was rapid. No patient followed for 1 year or more had a decrease in the best-corrected acuity, and 63% of this group had an average improvement of 1.5 lines with as much as five lines. The final refraction may take up to 6 months to stabilize. Complications consisted of epithelium and debris in the interface and focal necrosis of Bowman's membrane. The technique is difficult but may have application in the visual rehabilitation of the high myope.

    2017-08-01

    A green prospective based on the reuse of waste materials such as almond shells, orange peel and used cooking oil to manufacture soap is presented. In Portugal, thousands of tons of waste are generated from used cooking oil and production of nut shells' residues is growing every year. In addition, the high consumption of citrus fruits, oranges in particular, generates large amounts of citrus peel. Therefore, it is necessary to diversify reuse mechanisms of these wastes, in order to make them back into raw materials. Complying with this trend, this work was carried out by processing and grinding almond shells, treating used oil, processing orange peels and extracting limonene, formulating and producing soap, and performing an acceptance study of the final product. Results validated a high potential of the idea in the field of environmental education, so it can be replicated in practical classes. It can also be useful for waste management, and it can support the development of community projects on an ecological approach. Copyright © 2017 Elsevier Ltd. All rights reserved.

  10. Prospect Theory: Contributions to Understanding Actors, Causes and Consequences of Conflict in Africa

    Directory of Open Access Journals (Sweden)

    Wendy Trott

    2013-08-01

    Full Text Available Despite many recognized shortcomings, Rational Choice Theory remains the dominant perspective on decision-making in the literature on African conflict, whether overtly acknowledged or not. Prospect Theory, originally derived from the field of behavioural economics, can complement and advance this perspective not only by explaining the behaviour of actors, but also by allowing for predictions and the devising of strategies to avoid or end on-going conflicts based on a set of systematic biases that influence how actors make decisions. After a brief definition of Prospect Theory, this work will begin with an overview of the existing literature on decision-making as it relates to conflict, examine how Rational Choice is inadequate in explaining much human behaviour and thus how Prospect Theory can fill this gap. It will then move on to give a fuller definition of the various hypotheses derived from Prospect Theory that pertain to the study of conflict. An example of the application of Prospect Theory to a related field in which thorough research has been conducted, Deterrence Theory, will be used to demonstrate the model’s potential for study in other areas. This will be followed by a more in-depth analysis of the ways in which Prospect Theory can contribute to understanding the behaviour of actors in war, the causes of conflict, and the consequences in the African context. It will conclude with a summary and proposition for further research that can advance this analysis.

  11. Aerial thermography in archaeological prospection: Applications & processing

    Science.gov (United States)

    Cool, Autumn Chrysantha

    Aerial thermography is one of the least utilized archaeological prospection methods, yet it has great potential for detecting anthropogenic anomalies. Thermal infrared radiation is absorbed and reemitted at varying rates by all objects on and within the ground depending upon their density, composition, and moisture content. If an area containing archaeological features is recorded at the moment when their thermal signatures most strongly contrast with that of the surrounding matrix, they can be visually identified in thermal images. Research conducted in the 1960s and 1970s established a few basic rules for conducting thermal survey, but the expense associated with the method deterred most archaeologists from using this technology. Subsequent research was infrequent and almost exclusively appeared in the form of case studies. However, as the current proliferation of unmanned aerial vehicles (UAVs) and compact thermal cameras draws renewed attention to aerial thermography as an attractive and exciting form of survey, it is appropriate and necessary to reevaluate our approach. In this thesis I have taken a two-pronged approach. First, I built upon the groundwork of earlier researchers and created an experiment to explore the impact that different environmental and climatic conditions have on the success or failure of thermal imaging. I constructed a test site designed to mimic a range of archaeological features and imaged it under a variety of conditions to compare and contrast the results. Second, I explored a new method for processing thermal data that I hope will lead to a means of reducing noise and increasing the clarity of thermal images. This step was done as part of a case study so that the effectiveness of the processing method could be evaluated by comparison with the results of other geophysical surveys.

    The radon which diffuses in the ground and which migrates in the atmosphere is a natural radioactive tracer. The study of its production can give useful information on the uranium content and structure of the rocks from which it comes. Numerous authors have therefore suggested that uranium deposits be prospected by means of this radon. Three analytic methods have been used successively by the C.E.A.: the method of accumulation in a hole, the method of instantaneous sampling in the ground, and the method of sampling by scanning. Only the last has proved interesting and has been the object of systematic studies. It consists in purging the measurement recipient with air drawn from the probe and in measuring the variations in activity with time and with the volume drawn up, using a portable apparatus producing scintillations in a sulphurated flask. The first series of measurements made it possible to develop an apparatus (flow rate, hole depth, scintillating probe) and to distinguish between tbe activities of the thoron and of the radon by making two measurements at an interval of 54 seconds. A campaign of systematic sampling was then carried out. It made It possible to show the good reproducibility of the results obtained and tbe good agreement with conventional methods. This method is the best one for areas having large overlap. In the appendix the detector and its mode of use are briefly described, and the first results of an emanometric prospecting test in the Vendee mining division are given.

    This document presents site-specific data and sample development schedules for the first plant on line at 30 hydrothermal and 7 geopressured prospective sites (prospects) that are believed to be suited for supporting the geothermal generation of electricity. This report includes many prospects from an earlier METREK report on geothermal development scenarios. The list has been augmented with other sites chosen as development prospects by the division of Geothermal Energy (DGE) of the Energy Research and Development Administration (ERDA). The DGE additions include a general area called ''Cascade Range''. METREK has chosen the following specific Cascade Range Sites in place of that general area: Baker Hot Springs, Mount Hood, Lassen and Glass Mountain/ Diablo. All the prospects have been selected on the basis of current knowledge of hydrothermal and geopressured resources. The selection is intended for program planning purposes. Neither METREK nor the Federal government warrants that any of these sites will necessarily be developed, nor does their selection necessarily imply any commitment on the part of the Federal government to their development.

    Prospective memory is the ability to formulate and carry out actions at the appropriate time or in the appropriate context. This study aimed to identify the effect of hypnosis on prospective memory performance and to analyze the involvement of executive control processes in intention realization in a hypnotically altered state of consciousness. In 1 experiment, manipulating hypnotic instruction in a within-subject fashion, the authors explored the event-based prospective memory performance of 23 volunteers in 3 conditions: baseline, expectation, and execution. The primary result was that executing prospective memory responses, at the same accuracy rate, produced a significantly lower cost of ongoing responses in terms of response latency in the hypnotic state than in wake condition.

    Full Text Available Determination of the perceptions of the prospective teachers for the Information and Communications Technology (ICT terms have a remarkable potential to provide input for technology integration plans and ICT trainings. Within this context, the purpose of this study is to discover the metaphors constructed by prospective teachers for the ICT terms. Data were gathered from 180 prospective teachers through survey. 977 valid metaphors constructed by the participants were grouped into conceptual categories for the six ICT terms. The most common conceptual categories are “developing and changing” for technology, “making life easy” for computers and search engines, “limitless and endless” for the Internet, “means of communication” for social networks, and “addictive items” for video games. Future research should concentrate on investigating the match and mismatches between intended use of the ICT tools and the perception of the prospective teachers.

  4. Prospective Coding by Spiking Neurons.

    Johanni Brea

    2016-06-01

    Full Text Available Animals learn to make predictions, such as associating the sound of a bell with upcoming feeding or predicting a movement that a motor command is eliciting. How predictions are realized on the neuronal level and what plasticity rule underlies their learning is not well understood. Here we propose a biologically plausible synaptic plasticity rule to learn predictions on a single neuron level on a timescale of seconds. The learning rule allows a spiking two-compartment neuron to match its current firing rate to its own expected future discounted firing rate. For instance, if an originally neutral event is repeatedly followed by an event that elevates the firing rate of a neuron, the originally neutral event will eventually also elevate the neuron's firing rate. The plasticity rule is a form of spike timing dependent plasticity in which a presynaptic spike followed by a postsynaptic spike leads to potentiation. Even if the plasticity window has a width of 20 milliseconds, associations on the time scale of seconds can be learned. We illustrate prospective coding with three examples: learning to predict a time varying input, learning to predict the next stimulus in a delayed paired-associate task and learning with a recurrent network to reproduce a temporally compressed version of a sequence. We discuss the potential role of the learning mechanism in classical trace conditioning. In the special case that the signal to be predicted encodes reward, the neuron learns to predict the discounted future reward and learning is closely related to the temporal difference learning algorithm TD(λ.

    The future is uncertain because some forthcoming events are unpredictable and also because our ability to foresee the myriad consequences of our own actions is limited. Here we studied how humans select actions under such extrinsic and intrinsic uncertainty, in view of an exponentially expanding number of prospects on a branching multivalued visual stimulus. A triangular grid of disks of different sizes scrolled down a touchscreen at a variable speed. The larger disks represented larger rewards. The task was to maximize the cumulative reward by touching one disk at a time in a rapid sequence, forming an upward path across the grid, while every step along the path constrained the part of the grid accessible in the future. This task captured some of the complexity of natural behavior in the risky and dynamic world, where ongoing decisions alter the landscape of future rewards. By comparing human behavior with behavior of ideal actors, we identified the strategies used by humans in terms of how far into the future they looked (their "depth of computation") and how often they attempted to incorporate new information about the future rewards (their "recalculation period"). We found that, for a given task difficulty, humans traded off their depth of computation for the recalculation period. The form of this tradeoff was consistent with a complete, brute-force exploration of all possible paths up to a resource-limited finite depth. A step-by-step analysis of the human behavior revealed that participants took into account very fine distinctions between the future rewards and that they abstained from some simple heuristics in assessment of the alternative paths, such as seeking only the largest disks or avoiding the smaller disks. The participants preferred to reduce their depth of computation or increase the recalculation period rather than sacrifice the precision of computation.

    Full Text Available The philosophical foundations of the theory and practice of the creation of cosmic humanity as a process of the evolution of human civilization, the emergence into space, with the prospect of resettlement outside the Earth are considered. There is a connection between myths, fantasies, ideas, concepts and projects aimed at the exploration of outer space, the creation of cosmic humanity. A new and voluminous definition of cosmic humanity in the evolutionary paradigm is given. Cosmic humanity is (essence and 4 stages of evolution: 1. Humanity living on Earth, sensing, knowing, understanding its cosmic origin, relationship with the cosmos and cosmic destiny. 2. Humanity living on Earth, leading aerospace activity for the purposes of exploration and use of aerospace space (Heaven, Space for survival and development. 3. Humanity living on Earth and outside the Earth — in the solar system, preserving the Earth and mastering the Cosmos for survival and development. 4. Humanity, settled and living in the Cosmos. Now humanity is in the process of transition from the second to the third stage. In the process of this evolution, a complex transformation of man and society takes place. The problem-semantic field of cosmic humanity is described and its general model is presented. The meta-goal-setting is the justification of cosmic humanity with the application of the anthropic principle and its “active” super (post anthropic supplement: “Cosmic humanity has an evolutionary purpose to actively manage evolution: change man, humanity and the universe.” The evolution of the “cosmic dream”, goals and technologies of space activities is formalized in the form of a conceptual model. Challenges and negative trends are considered in connection with the crisis of space activity, criticism and attempts to limit the flights of people into space. The prototype of cosmic humanity, its basis and acting model is the cosmonauts’ community. The main

    As gas hydrate energy assessment matures worldwide, emphasis has evolved away from confirmation of the mere presence of gas hydrate to the more complex issue of prospecting for those specific accumulations that are viable resource targets. Gas hydrate exploration now integrates the unique pressure and temperature preconditions for gas hydrate occurrence with those concepts and practices that are the basis for conventional oil and gas exploration. We have aimed to assimilate the lessons learned to date in global gas hydrate exploration to outline a generalized prospecting approach as follows: (1) use existing well and geophysical data to delineate the gas hydrate stability zone (GHSZ), (2) identify and evaluate potential direct indications of hydrate occurrence through evaluation of interval of elevated acoustic velocity and/or seismic events of prospective amplitude and polarity, (3) mitigate geologic risk via regional seismic and stratigraphic facies analysis as well as seismic mapping of amplitude distribution along prospective horizons, and (4) mitigate further prospect risk through assessment of the evidence of gas presence and migration into the GHSZ. Although a wide range of occurrence types might ultimately become viable energy supply options, this approach, which has been tested in only a small number of locations worldwide, has directed prospect evaluation toward those sand-hosted, high-saturation occurrences that were presently considered to have the greatest future commercial potential.

    Prospect theory is widely viewed as the best available descriptive model of how people evaluate risk in experimental settings. According to prospect theory, people make decisions based on the potential value of losses and gains rather than the final outcome. People are risk-averse with respect to gains and risk-seeking with respect to losses, a phenomenon called ``loss aversion''. Despite of the fact that prospect theory has been well studied in behavioral economics at the theoretical level, there exist very few empirical research and most of them has been undertaken with micro-panel data. Here we analyze the trading activities of over 1.5 million members of an online financial trading community over 28 months, aiming to explore the large-scale empirical aspect of prospect theory. By analyzing and comparing the behaviour of ``winners'' and ``losers'', i.e., traders with positive or negative final net profit, we find clear evidence of the loss aversion phenomenon, an essence in prospect theory. This work demonstrates an unprecedented large-scale empirical evidence of prospect theory. It has immediate implication in financial trading, e.g., developing new trading strategies by minimizing the effect of loss aversion. It also provides opportunity to augment online social trading, where users are allowed to watch and follow the trading activity of others, by predicting potential winners based on their historical trading behaviour.

    Full Text Available Abstract Background Randomized, prospective trials involving multi-institutional collaboration have become a central part of clinical and translational research. However, data management and coordination of multi-center studies is a complex process that involves developing systems for data collection and quality control, tracking data queries and resolutions, as well as developing communication procedures. We describe DADOS-Prospective, an open-source Web-based application for collecting and managing prospective data on human subjects for clinical and translational trials. DADOS-Prospective not only permits users to create new clinical research forms (CRF and supports electronic signatures, but also offers the advantage of containing, in a single environment, raw research data in downloadable spreadsheet format, source documentation and regulatory files stored in PDF format, and audit trails. Results Feedback from formal and field usability tests was used to guide the design and development of DADOS-Prospective. To date, DADOS-Prospective has been implemented in five prospective clinical studies at our institution. Four of these studies are still in the CRF creation phase and one study has been entirely launched. Conclusion DADOS-Prospective has significant advantages over existing Web-based data collecting programs. At our institution, it has been demonstrated to be an efficient tool for prospective clinical studies.

    2009-01-01

    A well-defined granular layer 4 is a defining cytoarchitectonic feature associated with sensory areas of mammalian cerebral cortex, and one with hodological significance: the local axons ascending from cells in thalamorecipient layer 4 and connecting to layer 2/3 pyramidal neurons form a major feedforward excitatory interlaminar projection. Conversely, agranular cortical areas, lacking a distinct layer 4, pose a hodological conundrum: without a laminar basis for the canonical layer 4-->2/3 pathway, what is the basic circuit organization? This review highlights current challenges and prospects for local-circuit electroanatomy and electrophysiology in agranular cortex, focusing on the mouse. Different lines of evidence, drawn primarily from studies of motor areas in frontal cortex in rodents, support the view that synaptic circuits in agranular cortex are organized around prominent descending excitatory layer 2/3-->5 pathways targeting multiple classes of projection neurons.

    Full Text Available Jalil Safaei Department of Economics, University of Northern British Columbia, Prince George, BC, CanadaBackground: There is a vast body of literature on deliberative, participative, or engaged democracy. In the area of health care there is a rapidly expanding literature on deliberative democracy as embodied in various notions of public engagement, shared decision-making (SDM, patient-centered care, and patient/care provider autonomy over the past few decades. It is useful to review such literature to get a sense of the challenges and prospects of introducing deliberative democracy in health care.Objective: This paper reviews the key literature on deliberative democracy and SDM in health care settings with a focus on identifying the main challenges of promoting this approach in health care, and recognizing its progress so far for mapping out its future prospects in the context of advanced countries.Method: Several databases were searched to identify the literature pertinent to the subject of this study. A total of 56 key studies in English were identified and reviewed carefully for indications and evidence of challenges and/or promising avenues of promoting deliberative democracy in health care.Results: Time pressure, lack of financial motivation, entrenched professional interests, informational imbalance, practical feasibility, cost, diversity of decisions, and contextual factors are noted as the main challenges. As for the prospects, greater clarity on conception of public engagement and policy objectives, real commitment of the authorities to public input, documenting evidence of the effectiveness of public involvement, development of patient decision supports, training of health professionals in SDM, and use of multiple and flexible methods of engagement leadership suited to specific contexts are the main findings in the reviewed literature.Conclusion: Seeking deliberative democracy in health care is both challenging and rewarding.

    Sudan is the largest country in Africa with an area of about 2.5 million km2; the country hosts a population of about 31 million people. About two-thirds of the country area is located within arid and semi-arid regions. Recently, especially during the last half of the previous century, these regions were subject to various forms of land degradation. This paper discusses the general prospects and constraints of desert agriculture. It also presents a detailed case study of West Omdurman, which is located in a semi-desert climatic zone. The ambitious plans to utilise the area for agricultural production were initiated because of the relatively fertile soil, availability of water and the proximity of the area to marketing and export centres. The paper discusses the different land use systems experienced in the area, reasons for failure are identified and possible remedies discussed. In addition, constraints facing the proposed West Omdurman Canal Project are also discussed. Finally, the paper reviews the major research findings of Rawakeeb Dryland Research Center with regard to promoting agricultural productivity.

    Full Text Available Background: Neurocutaneous syndromes (NCS are a group of genetic disorders that produce a variety of developmental abnormalities of the skin along with an increased risk of neurological complications. Cutaneous manifestations usually appear early in life and progress with time, but neurological features generally present at a later age. There is a paucity of data regarding the evolution of skin lesions and their correlation with the central nervous system involvement in children. Aim: The primary objective was to track the course of skin lesions in various forms of NCS in the pediatric age group. Our secondary aim was to assess whether there was any predictive value of the lesions in relation to the neurological manifestations. Materials and Methods: This prospective longitudinal study was conducted at a tertiary care pediatric dermatology referral clinic of the Institute of Child Health, Kolkata, West Bengal. Children between the age group 0 and 12 years were included in the study on the basis of standard diagnostic criteria for different NCS, during the period from March, 2000 to February, 2004, and each of the enrolled cases were followed up for a duration of six years. Results: The study population comprised of 67 children (35 boys, 32 girls.The mean age of presentation was 33.8±27.8 months (range 10 days to 111 months. The various forms of NCS observed was neurofibromatosis 1(NF1 (n=33, tuberous sclerosis complex (TSC (n=23, Sturge Weber syndrome (n=6, ataxia telangiectasia (n=2, PHACE syndrome (n=1, incontinentia pigmenti (n=1, and hypomelanosis of Ito (n=1. The presentations were varied, ranging from predominantly cutaneous to primarily neurological, depending on the disease entity and age group concerned. There was a significant increase in the number of café au lait macules (CALMs with time (P=0.0002 in NF1, unlike that of hypopigmented macules of TSC (P=0.15.

    Microbial prospecting of hydrocarbons is based on the detection of anomalous population of hydrocarbon oxidizing bacteria in the surface soils, indicates the presence of subsurface oil and gas accumulation. The technique is based on the seepage of light hydrocarbon gases such as C1-C4 from the oil and gas pools to the shallow surface that provide the suitable conditions for the development of highly specialized bacterial population. These bacteria utilize hydrocarbon gases as their only food source and are found enriched in the near surface soils above the hydrocarbon bearing structures. The methodology involves the collection of soil samples from the survey area, packing, preservation and storage of samples in pre-sterilized sample bags under aseptic and cold conditions till analysis and isolation and enumeration of hydrocarbon utilizing bacteria such as methane, ethane, propane, and butane oxidizers. The contour maps for the population density of hydrocarbon oxidizing bacteria are drawn and the data can be integrated with geological, geochemical, geophysical methods to evaluate the hydrocarbon prospect of an area and to prioritize the drilling locations thereby reducing the drilling risks and achieve higher success in petroleum exploration. Microbial Prospecting for Oil and Gas (MPOG) method success rate has been reported to be 90%. The paper presents details of microbial prospecting for oil and gas studies, excellent methodology, future development trends, scope, results of study area, case studies and advantages.

    Full Text Available Com o objetivo de avaliar a junção tiroidiana após uso crônico da amiodarona, em área de deficiência de iodo e endemia chagásica, 24 pacientes foram analisados antes e após três e nove meses de uso da droga. A avaliação constou de exame clínico, dosagem sérica de T4, T3, rT3, TSH, anticorpo antitiroglobulina e TSH 30 minutos após infusão venosa de uma ampola de 200µg de TRH. A captação do iodo radioativo 131 e a cintilografia datiróide foram realizadas antes e aos 9 meses após tratamento. Disfunção tiroidiana ocorreu em 20,8% dos pacientes sendo 12,5% de hipertiroidismo e 8,3% de hipotiroidismo, com anticorpos antitiroglobulina negativos. Captação do iodo radioativo 131 foi positiva em um paciente hipertiroideo com bócio. O diagnóstico de hipertiroidismo foi melhor evidenciado pela resposta reduzida ou bloqueada do TSH ao TRH e não pela concentração do T3 no soro e o de hipotiroidismo pela concentração elevada do TSH. O TSH elevado desde o início do tratamento pode predispor ao aparecimento de bócio. Concluímos que o uso da amiodarona em nossa região deve serjudiciosamente analisado, sendo a função tiroidiana cuidadosamente monitorizada antes e durante o tratamento.In order to evaluate the development of thyroid dysfunction during chronic amiodarone treatment in an area deficient in iodine and endemic for Chagas 'disease, a group of 24patients wasprospectively studied.

    Between 1976 and 1989 the Queensland Department of Mines (now the Department of Resource Industries) drilled 20 widely spaced, fully and partly cored holes in an area south of Emerald between Fairbairn reservoir and Mount Alexander. These holes were drilled to test the coal resource potential of the Permian age Reids Dome beds on the northwestern margin of the Denison Trough, southwest Bowen Basin. Eighteen holes intersected thick coal seams within the Reids Dome beds underlying an area about 8 km wide and 24 km long. Numerous seams up to 11 m thick were intersected at depths ranging from 45 m to 476 m. Analysis indicated these seams to be of high quality, being low ash, low sulphur, high volatile non-coking coal with a high calorific value. The study area has been divided along structural trends into three parts or prospects for the purpose of resource description: Cullin-la-ringo in the north, Gindie Creek in the centre and Minerva in the south. Current borehole spacing in these areas is insufficient to allow more than an inferred estimate of in situ coal resources. A total inferred resource of approximately 3 800 million tonnes in situ has been identified to date. Significant potential exists for further expansion of these resources in the Gindie Creek and Minerva prospects, where little drilling has yet taken place. Some potential for resources amenable to opencut mining is indicated in the Minerva prospect, where areas free of basalt cover have been identified.

    Full Text Available Countries in sub-Saharan Africa are among the least developed in the world and hunger and poverty remains widespread in most of the rural communities. Reducing hunger and chronic under nourishment through the introduction of productive livestock as a source of traction and manure for crop production, transport, milk and meat is deemed to be a fundamental first step towards better rural development. The presence of the tsetse fly in one third of the African continent and the disease trypanosomosis it transmits is considered the major barrier to the development of productive livestock. Despite the yearly administration of 35 million doses of trypanocidal drugs (at US$ 1 per dose, African farmers lose 3 million cattle every year to the disease and annual direct economic losses are estimated at US$ 600 to 1200 million. Tsetse flies mainly affect the rural poor and are rightfully considered 'a root cause of poverty ' in Africa . The most desirable way of containing the disease trypanosomosis is undoubtedly the elimination of entire populations of the vector from delimited geographical areas using an integration of various control tactics, i.e. an areawide integrated pest management (AW-IPM approach. Efficient methods to suppress or even eliminate tsetse populations have been available for the last 50 years and are mostly based on the use of insecticides or entail devices that attract and kill. Nevertheless, despite gigantic efforts in the past century, there are only a few examples where the elimination of tsetse flies has proven to be sustainable, e.g. the elimination of Glossina pallidipes Austen from South Africa in the 1950 's using mainly aerial spraying of residual insecticides or the creation of a zone free of Glossina austeni Newstead on Unguja Island of Zanzibar (1994-1997 through the integration of various control tactics including the release of sterile insects.

    Two common problems affect integration of exploration criteria for mineral prospectivity mapping (MPM) in geographic information system (GIS): (a) stochastic error associated with sufficiency in number of known mineral occurrences (KMOs) used to estimate evidential weights and (b) systemic error associated with subjectivity of expert judgment applied to process, analyze, and assign weights to evidential data. In this paper we used logistic sigmoid (or S-shaped) function to transform continuous-value evidential data into logistic space without using KMOs as in data-driven MPM and without discretization of evidential data into classes by using arbitrary intervals based on expert judgment as in knowledge-driven MPM. We generated a prospectivity model using discretized evidential data as well. Then, we compared the prospectivity models generated using continuous- and discretized-value evidential data and demonstrated that the former is better model for selecting target areas for further exploration.

    2017-09-01

    Nb3Sn superconductors have significant applications in constructing high-field (>10 T) magnets. This article briefly reviews development of Nb3Sn superconductor and proposes prospects for further improvement. It is shown that significant improvement of critical current density (J c) is needed for future accelerator magnets. After a brief review of the development of Nb3Sn superconductors, the factors controlling J c are summarized and correlated with their microstructure and chemistry. The non-matrix J c of Nb3Sn conductors is mainly determined by three factors: the fraction of current-carrying Nb3Sn phase in the non-matrix area, the upper critical field B c2, and the flux line pinning capacity. Then prospects to improve the three factors are discussed respectively. An analytic model was developed to show how the ratios of precursors determine the phase fractions after heat treatment, based on which it is predicted that the limit of current-carrying Nb3Sn fraction in subelements is ∼65%. Then, since B c2 is largely determined by the Nb3Sn stoichiometry, a thermodynamic/kinetic theory is presented to show what essentially determines the Sn content of Nb3Sn conductors. This theory explains the influences of Sn sources and Ti addition on stoichiometry and growth rate of Nb3Sn layers. Next, to improve flux pinning, previous efforts in this community to introduce additional pinning centers to Nb3Sn wires are reviewed, and an internal oxidation technique is described. Finally, prospects for further improvement of non-matrix J c of Nb3Sn conductors are discussed, and it is seen that the only opportunity for further significantly improving J c lies in improving flux pinning.

    Objective: To evaluate the clinical efficacy of polycarboxylate cement as retrograde filling material. Design: A prospective clinical study was made of 25 patients subjected to periapical surgery with ultrasound and magnifying loupes, in which polycarboxylate cement was used as retrograde filling material. Measurements were made of the area and diameter of the lesions pre- and postoperatively, and 6 and 12 months after the operation. The apical resection and retrograde filling areas were also measured, and the prognosis following surgery was recorded. Results: A total of 23 patients with 31 apicoectomized teeth were studied (2 patients being lost to follow-up). The mean area of the periapical lesions before surgery was 52.25 mm2, with a mean major diameter of 6.1 mm and a mean lesser diameter of 4.8 mm. The success rate after 12 months was 54.7%, according to the criteria of Von Arx and Kurt. The prognosis was poorer in females, in larger lesions, and in cases with larger retrograde filling areas. Conclusions: Polycarboxylate cement offers good results, with important bone regeneration after periapical surgery. Key words: Periapical surgery, endodontic treatment, polycarboxylate cement.

    2005-01-01

    Recently, in order to explore the mechanism behind wealth or income distribution, several models have been proposed by applying principles of statistical mechanics. These models share some characteristics, such as consisting of a group of individual agents, a pile of money and a specific trading rule. Whatever the trading rule is, the most noteworthy fact is that money is always transferred from one agent to another in the transferring process. So we call them money transfer models. Besides explaining income and wealth distributions, money transfer models can also be applied to other disciplines. In this paper we summarize these areas as statistical distribution, economic mobility, transfer rate and money creation. First, money distribution (or income distribution) can be exhibited by recording the money stock (flow). Second, the economic mobility can be shown by tracing the change in wealth or income over time for each agent. Third, the transfer rate of money and its determinants can be analyzed by tracing t...

    2017-08-01

    Mental toughness (MT) has become a popular area of investigation and practice within sport and exercise psychology over the past two decades. Since the turn of the twenty first century, there have been hundreds of studies published on mental toughness, yet concerns remain about the conceptualisation and measurement of mental toughness. In this paper, I take stock of past work with the goal of clarifying and elaborating the most fundamental and common aspects of MT. I also look to the future and outline key substantive and methodological issues that may offer the greatest potential for refining the conceptualisation of MT and contributing to theory building on this concept. My hope is that this information will provide a platform from which to foster coherent and systematic scholarly work on MT. Copyright © 2017 Elsevier Ltd. All rights reserved.

    2017-02-01

    Understanding brain organization of speech production has been a principal goal of neuroscience. Historically, brain speech production has been associated with so-called Broca’s area (Brodmann area –BA- 44 and 45), however, modern neuroimaging developments suggest speech production is associated with networks rather than with areas. The purpose of this paper was to analyze the connectivity of BA47 ( pars orbitalis) in relation to language . A meta-analysis was conducted to assess the language network in which BA47 is involved. The Brainmap database was used. Twenty papers corresponding to 29 experimental conditions with a total of 373 subjects were included. Our results suggest that BA47 participates in a “frontal language production system” (or extended Broca’s system). The BA47  connectivity found is also concordant with a minor role in language semantics. BA47 plays a central role in the language production system.

  1. Prospect theory for online financial trading.

    Directory of Open Access Journals (Sweden)

    Yang-Yu Liu

    Full Text Available Prospect theory is widely viewed as the best available descriptive model of how people evaluate risk in experimental settings. According to prospect theory, people are typically risk-averse with respect to gains and risk-seeking with respect to losses, known as the "reflection effect". People are much more sensitive to losses than to gains of the same magnitude, a phenomenon called "loss aversion". Despite of the fact that prospect theory has been well developed in behavioral economics at the theoretical level, there exist very few large-scale empirical studies and most of the previous studies have been undertaken with micro-panel data. Here we analyze over 28.5 million trades made by 81.3 thousand traders of an online financial trading community over 28 months, aiming to explore the large-scale empirical aspect of prospect theory. By analyzing and comparing the behavior of winning and losing trades and traders, we find clear evidence of the reflection effect and the loss aversion phenomenon, which are essential in prospect theory. This work hence demonstrates an unprecedented large-scale empirical evidence of prospect theory, which has immediate implication in financial trading, e.g., developing new trading strategies by minimizing the impact of the reflection effect and the loss aversion phenomenon. Moreover, we introduce three novel behavioral metrics to differentiate winning and losing traders based on their historical trading behavior. This offers us potential opportunities to augment online social trading where traders are allowed to watch and follow the trading activities of others, by predicting potential winners based on their historical trading behavior.

    Mistrík, Ivan; Grundy, John; van der Hoek, André; Whitehead, Jim

    Much work is presently ongoing in collaborative software engineering research. This work is beginning to make serious inroads into our ability to more effectively practice collaborative software engineering, with best practices, processes, tools, metrics, and other techniques becoming available for day-to-day use. However, we have not yet reached the point where the practice of collaborative software engineering is routine, without surprises, and generally as optimal as possible. This chapter summarizes the main findings of this book, draws some conclusions on these findings and looks at the prospects for software engineers in dealing with the challenges of collaborative software development. The chapter ends with prospects for collaborative software engineering.

    Objectives. This study aimed to clarify the relationship between community water fluoridation (CWF) and IQ. Methods. We conducted a prospective study of a general population sample of those born in Dunedin, New Zealand, between April 1, 1972, and March 30, 1973 (95.4% retention of cohort after 38 years of prospective follow-up). Residence in a CWF area, use of fluoride dentifrice and intake of 0.5-milligram fluoride tablets were assessed in early life (prior to age 5 years); we assessed IQ repeatedly between ages 7 to 13 years and at age 38 years. Results. No clear differences in IQ because of fluoride exposure were noted. These findings held after adjusting for potential confounding variables, including sex, socioeconomic status, breastfeeding, and birth weight (as well as educational attainment for adult IQ outcomes). Conclusions. These findings do not support the assertion that fluoride in the context of CWF programs is neurotoxic. Associations between very high fluoride exposure and low IQ reported in previous studies may have been affected by confounding, particularly by urban or rural status.

    The incidence and risk factors for acute diabetes insipidus after severe head injury and the effect of this complication on outcomes have not been evaluated in any large prospective studies. We conducted a prospective study of all patients admitted to the surgical ICU of a Level I trauma center with severe head injury (head Abbreviated Injury Score [AIS] >or= 3). The following potential risk factors with p risk factors for diabetes insipidus and its association with mortality: age, mechanism of injury (blunt or penetrating), blood pressure, Glasgow Coma Scale, Injury Severity Score, head and other body area AIS, skull fracture, cerebral edema and shift, intracranial hemorrhage, and pneumocephaly. There were 436 patients (blunt injuries, 392; penetrating injuries, 44); 387 patients had isolated head injury. Diabetes insipidus occurred in 15.4% of all patients (blunt, 12.5%; penetrating, 40.9%; p diabetes insipidus. Independent risk factors for diabetes insipidus in isolated head injury were Glasgow Coma Scale3. Diabetes insipidus was an independent risk factor for death (adjusted odds ratio, 3.96; 95% CI [1.65, 9.72]; adjusted p value = 0.002). The incidence of acute diabetes insipidus in severe head injury is high, especially in penetrating injuries. Independent risk factors for diabetes insipidus include a Glasgow Coma Scale3. Acute diabetes insipidus was associated with significantly increased mortality.

    The geology of Western Greece is dominated by the most external zones of the Hellenide fold-and-thrust belt, namely the Pre-Apulian (or Paxoi) and Ionian zones. With Western Greece and Albania having undergone, in broad terms, similar geological histories, also the hydrocarbon potentials of both areas may be compared. Likewise, the hydrocarbon potential of Italy's Apulian Platform, adjoining in the westerly offshore, may serve as an analogue. Three basin types within Western Greece that deserve hydrocarbon exploration have been examined and are grouped, correlated to major tectonic features, namely foreland (Ionian thrusts' foreland basin), piggy-back (Ionian thrusts' back-arc basin) and strike-slip basins. Additionally, strike-slip basins are further subdivided into the basin north of the Borsh-Khardhiqit strike-slip fault and the Preveza basin, north of Cephalonia transfer fault. Their filling histories suggest the occurrence of Mesozoic carbonate plays and Oligocene/Miocene sandstone plays both for oil and gas.

  10. Prospects of Nanobiomaterials for Biosensing

    2011-01-01

    Full Text Available Progress and development in biosensor development will inevitably focus upon the technology of the nanomaterials that offer promise to solve the biocompatibility and biofouling problems. The biosensors using smart nanomaterials have applications for rapid, specific, sensitive, inexpensive, in-field, on-line and/or real-time detection of pesticides, antibiotics, pathogens, toxins, proteins, microbes, plants, animals, foods, soil, air, and water. Thus, biosensors are excellent analytical tools for pollution monitoring, by which implementation of legislative provisions to safeguard our biosphere could be made effectively plausible. The current trends and challenges with nanomaterials for various applications will have focus biosensor development and miniaturization. All these growing areas will have a remarkable influence on the development of new ultrasensitive biosensing devices to resolve the severe pollution problems in the future that not only challenges the human health but also affects adversely other various comforts to living entities. This review paper summarizes recent progress in the development of biosensors by integrating functional biomolecules with different types of nanomaterials, including metallic nanoparticles, semiconductor nanoparticles, magnetic nanoparticles, inorganic/organic hybrid, dendrimers, and carbon nanotubes/graphene.

    Reduced memory specificity is associated with depression, post-traumatic stress disorder (PTSD), and some other forms of psychopathology. Reduced memory specificity is also associated with reduced specificity of envisioned future events. Research in this area has mostly relied on cue-word methods that include explicit instructions to develop specific memories of future events. These methods are limited in their ability to assess how participants habitually remember the past and imagine the future when the specificity constraints inherent in the cue-word task are removed. Sentence completions tasks have been developed that can be used to assess habitual patterns of memory and prospection. Little is known about the association of habitual memory and prospection with concurrently and prospectively assessed psychopathology. In the current study 142 participants completed sentence completion tasks tapping habitual memory and prospection at baseline and completed measures tapping psychological symptoms at baseline and 1 year later. Among other things, it was found that reduced memory specificity (but not reduced future specificity) was associated with concurrent and later depression, as well as with symptom levels of PTSD tapped 1 year beyond baseline.

    This paper describes three case studies for monitoring ground water aquifers by electrical prospecting. An example in the Hofu plain, Yamaguchi Prefecture is presented, where the ground water environment has been monitored for more than 30 years from the viewpoint of hydrology. Then, transition from the fresh ground water to sea water is evaluated by a sharp boundary as salt-water wedges through the field survey in a coastal area of a large city for a short term using vertical electrical prospecting. Moreover, streaming potential measurements are described to grasp the real-time behavior of ground water flow. From the long-term monitoring of ground water aquifer, it was found that the variation of ground water streaming can be evaluated by monitoring the long-term successive change in the resistivity of ground water aquifer. From the vertical electrical prospecting, water quality can be immediately judged through data analysis. From the results of streaming potential measurements and vertical electrical prospecting using Schlumberger method, streaming behavior of ground water in the area of spring water source can be estimated by determining three-dimensional resistivity structure. 17 refs., 15 figs.

    Full Text Available The development of the DNA recombinant technology has provided the transfer of a single or several genes within or among species whereby organisms with new traits were developed. Such organisms have been called genetically modified organisms. The first genetically modified varieties of cultivated plants entered the market in 1996 and since then areas sown with such crops has been increasing, amounting to 60 M ha in 2002. During the stated period, genetically modified varieties and hybrids of cultivated plants were developed with a gene introduced for tolerance to herbicides, resistance to insects, prolonged maturity period and improved quality. However, heavy disputes have arisen all over the world relating the possible gain and potential risks from the growth and utilization of modified crops. First of all, there are ethical issues related directly to gene transfer from a species to a species, then effects of the introduced gene on the environment and human health, economical justification of cultivating genetically modified crops, consumers confidence in the legislation, labeling the products encompassing a genetic modification, effects on the global market and ever increasing food requirements. The effect of products derived from genetically modified plants on human health depends on a specific content of a product itself and can potentially be useful if a product contains an increased content of vitamins, with an allergen removed, or potentially harmful, if a new allergen or a toxin were introduced by genetic modifications. Each genetically modified product is subjected to a rigorous testing of its safety prior to its introduction into a food chain. It encompasses molecular, biochemical, toxicological, nutritional and allergenic tests. Many countries apply legislation that stipulates labeling of genetically modified products, whereby the fact that the commodity encompasses products of genetic modification is clearly pointed out. .

    Full Text Available The Northern Sea Route (NSR represents a serious alternative to traditional so-called «southern» sea transportation routes passing through the Suez Canal. Data on the present and on most optimistic prospective scopes of transportation over NSR for different types of goods are presented in the article. Among main factors working for the optimistic perspective with respect of NSR there are measurements stipulated in several Russian governmental decrees, global rise in temperature and feasibility to develop natural resources abundantly available in the arctic areas of Russia. Still, there are negative factors such as the need of massive investment to transportation means and to local infrastructure, risks associated with the probability of particularly severe arctic natural phenomena and provision for safety in many aspects.

    Genome editing is the practice of making predetermined and precise changes to a genome by controlling the location of DNA DSBs (double-strand breaks) and manipulating the cell's repair mechanisms. This technology results from harnessing natural processes that have taken decades and multiple lines of inquiry to understand. Through many false starts and iterative technology advances, the goal of genome editing is just now falling under the control of human hands as a routine and broadly applicable method. The present review attempts to define the technique and capture the discovery process while following its evolution from meganucleases and zinc finger nucleases to the current state of the art: TALEN (transcription-activator-like effector nuclease) technology. We also discuss factors that influence success, technical challenges and future prospects of this quickly evolving area of study and application.

    2014-06-01

    Full Text Available Reports of functional problems are common among Veterans who served post-9/11 (more than 25% report functional difficulties in at least one domain. However, little prospective work has examined the risk and protective factors for functional difficulties among Veterans. In a sample of recently separated Marines, we used stepwise logistic and multiple regressions to identify predictors of functional impairment, including work-related problems, financial problems, unlawful behavior, activity limitations due to mental health symptoms, and perceived difficulty reintegrating into civilian life. Posttraumatic stress disorder symptoms assessed both before and after military separation significantly predicted functional difficulties across all domains except unlawful behavior. Certain outcomes, such as unlawful behavior and activity limitations due to mental health symptoms, were predicted by other or additional predictors. Although several forms of functioning were examined, the list was not exhaustive. The results highlight a number of areas where targeted interventions may facilitate the reintegration of military servicemembers into civilian life.

  19. A topology of mineralization and its meaning for prospecting

    Neuerburg, G.J.

    1982-01-01

    Epigenetic mineral deposits are universal members of an orderly spatial and temporal arrangement of igneous rocks, endomorphic rocks, and hydrothermally altered rocks. The association and sequence of these rocks is invariant whereas the metric relations and configurations of the properties of these rocks are unlimited in variety. This characterization satisfies the doctrines of topology. Metric relations are statistical, and their modes are among the better guides to optimal areas for exploration. Metric configurations are graphically irregular and unpredictable mathematical surfaces like mountain topography. Each mineral edifice must be mapped to locate its mineral deposits. All measurements and observations are only positive or neutral for the occurrence of a mineral deposit. Effective prospecting is based on an increasing density of positive data with proximity to the mineral deposit. This means sampling for maximal numbers of positive data, pragmatically the highest ore-element assays at each site, by selecting rock showing maximal development of lode attributes.

    Loneliness has been linked cross-sectionally to emotional skill deficits (e.g., Zysberg, 2012), but missing from the literature is a longitudinal examination of these relationships. The present study fills that gap by examining the prospective relationships between loneliness and emotional functioning in young adolescents in England. One hundred and ninety-six adolescents aged 11-13 years (90 females) took part in the study and completed the youth version of the Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT-YV) and the peer-related subscale of the Loneliness and Aloneness Scale for Children and Adolescents (LACA) at two time points, which were 10 months apart. Prospective associations were obtained for male and female adolescents separately using cross-lagged statistical techniques. Our results showed prospective links between understanding and managing emotions and loneliness for both females and males. Perceiving and using emotions were prospectively linked to loneliness in males only. Possible explanations and directions for future research are discussed.

    Ligninolytic extracellular enzymes, including lignin peroxidase, are topical owing to their high redox potential and prospective industrial applications. The prospective applications of lignin peroxidase span through sectors such as biorefinery, textile, energy, bioremediation, cosmetology, and dermatology industries. The litany of potentials attributed to lignin peroxidase is occasioned by its versatility in the degradation of xenobiotics and compounds with both phenolic and non-phenolic constituents. Over the years, ligninolytic enzymes have been studied however; research on lignin peroxidase seems to have been lagging when compared to other ligninolytic enzymes which are extracellular in nature including laccase and manganese peroxidase. This assertion becomes more pronounced when the application of lignin peroxidase is put into perspective. Consequently, a succinct documentation of the contemporary functionalities of lignin peroxidase and, some prospective applications of futuristic relevance has been advanced in this review. Some articulated applications include delignification of feedstock for ethanol production, textile effluent treatment and dye decolourization, coal depolymerization, treatment of hyperpigmentation, and skin-lightening through melanin oxidation. Prospective application of lignin peroxidase in skin-lightening functions through novel mechanisms, hence, it holds high value for the cosmetics sector where it may serve as suitable alternative to hydroquinone; a potent skin-lightening agent whose safety has generated lots of controversy and concern. © 2016 The Authors.

    The Paleoproterozoic boron deposits in east Liaoning occur in Mg- rich marble of Li' eryu Formation of Liaohe group. The mineralization was controlled by stratigraphic lithology. The volcano ~ sedimentation is the material base of ore-formation. Boron mainly derived from volcanic source. Boron in Li' eryu formation was activated and transferred by migmatization and then deposited into ore when metasomatism occurrs in Mg - rich marble. Structural deformation reconstructed the boron ore bodies. Meanwhile, ore - bearing hyd~othermal solution produced by structural deformation and remetasomated the host - ore rocks or filled in fissure of ore. Boron deposit is a stratabound deposit, which formed by migmatization and structural deformation mineralization.

    1984-01-01

    A geologic and mineral survey was conducted in the Pyramid Roadless Area, California. The area contains mineral showings, but no mineral-resource potential was identified during our studies. Three granodiorite samples on the west side of the roadless area contained weakly anomalous concentrations of uranium. Two samples of roof-pendant rocks, one metasedimentary rock and one metavolcanic rock, contain low concentrations of copper, and of copper and molybdenum, respectively. Although none was identified, the geologic terrane is permissive for mineral occurrences and large-scale, detailed geologic mapping of the areas of metasedimentary and metavolcanic roof pendants in the Pyramid Roadless Area could define a mineral-resource potential for tungsten and precious metals.

    2012-11-01

    Full Text Available Background: Apathy is common in aging, but the processes underlying its different components are still unclear. The aim of this study was to examine the relationships between apathy and prospective memory (PM, a process involved in the execution of delayed intentions. Methods: Fifty elderly participants completed a PM task and a working memory task. Close relatives of the participants were given the Apathy Inventory, which assesses three dimensions of apathy (lack of initiative, lack of interest, emotional blunting, and a negative mood scale. Results: Correlation analyses showed strong relationships between PM and lack of initiative and interest. These relations remain significant even after controlling for global cognitive functioning, working memory, processing speed and negative mood. Conclusion: This study sheds new light on the cognitive mechanisms associated with apathy in aging and opens up interesting prospects for psychological intervention.

  13. Detection prospects of singlet fermionic dark matter

    CERN Document Server

    Esch, Sonja; Yaguna, Carlos E

    2013-01-01

    A singlet fermion which interacts only with a new singlet scalar provides a viable and minimal scenario that can explain the dark matter. The singlet fermion is the dark matter particle whereas the new scalar mixes with the Higgs boson providing a link between the dark matter sector and the Standard Model. In this paper, we present an updated analysis of this model focused on its detection prospects. Both, the parity-conserving case and the most general case are considered. First, the full parameter space of the model is analyzed, and the regions compatible with the dark matter constraint are obtained and characterized. Then, the implications of current and future direct detection experiments are taken into account. Specifically, we determine the regions of the multidimensional parameter space that are currently excluded and those that are going to be probed by next generation experiments. Finally, indirect detection prospects are discussed and the expected signal at neutrino telescopes is calculated.

  15. Future prospects for secondary-beam production

    CERN Document Server

    Schmidt, K H; Enqvist, T; Junghans, A R; Rejmund, F; Ricciardi, M V

    2002-01-01

    This contribution discusses the characteristics of different types of nuclear reactions and the influence of the beam energy in view of future prospects for secondary-beam production. First, electronic interactions in the target are considered because they define the usable target thickness. Rather high beam energies are advantageous. Secondly, the nuclear-reaction aspects are discussed. Three reaction mechanisms provide the most promising prospects for the production of secondary beams. Fusion is best suited for the production of nuclei near the proton drip line and for the heaviest elements. Fission specifically populates mid-mass neutron-rich isotopes. Fragmentation and spallation reactions represent rather universal production mechanisms for both neutron-deficient and neutron-rich exotic nuclei, since the fluctuations in the N-over-Z ratio are very important. Due to these large fluctuations, this is the most promising reaction mechanism to reach extremely exotic nuclei over the whole mass range, if suffic...

    2005-01-01

    The history, present status and future prospects of adjuvants application in herbicides were briefly reviewed. Adjuvants can be separated into two groups, activator adjuvants and utility adjuvants. The former directly enhances the efficacy of a herbicide through increasement of herbicide absorption, spreading, cuticular penetration, rainfastness and retention enhancement, and photodegradation of the herbicide can also be decreased. And the latter is utilized for improving application characteristics, behaviors and physical properties of herbicides and reducing or minimizing unwanted side effects on application.

    Measurements of the linear polarization of the cosmic microwave background provide a direct window into the physics of inflation. The experimental challenges are daunting: not only is the predicted signal faint compared to the photon noise limit, but it is hidden behind competing foregrounds from both local and cosmic sources. I will discuss the experimental response to these challenges and the prospects for eventual detection and characterization of the inflationary signal.

    Full Text Available As in many other countries, following the 2007-2008 education year when media literacy courses began to be included in the curricula, media literacy has become one of the discussion topics among educators and decision makers in Turkey. Discussion topics related to media literacy have included who is going to give the media literacy courses, what qualifications will be sought out in media literacy education teachers, what will be included in the media literacy curriculum in terms of its content, and at what level the media literacy course will be given. The current study which aims to examine media literacy levels of prospective teachers utilized thesurvey method. The sample of the study included prospective teachers (480 attending Elementary School Education, Social Studies Education and Turkish Language Education departments in the Education Faculty at the Dumlupinar University in the 2008-2009 education year. The results of the study showed that prospective teachers have a low level of reaction to media messages, do not educate people around enough about the effects of media, but make use of different sources of media to gain information, and are cognizant of media literacy.

    Recent research on Prospective Energy and Material Resources on Asteroids. Carefully edited book dedicated to Asteroids prospective energy and material resources. Written by leading experts in the field. The Earth has limited material and energy resources while these resources in space are virtually unlimited. Further development of humanity will require going beyond our planet and exploring of extraterrestrial resources and sources of unlimited power. Thus far, all missions to asteroids have been motivated by scientific exploration. However, given recent advancements in various space technologies, mining asteroids for resources is becoming ever more feasible. A significant portion of asteroids value is derived from their location; the required resources do not need to be lifted at a great expense from the surface of the Earth. Resources derived from Asteroid not only can be brought back to Earth but could also be used to sustain human exploration of space and permanent settlements in space. This book investigates asteroids' prospective energy and material resources. It is a collection of topics related to asteroid exploration, and utilization. It presents past and future technologies and solutions to old problems that could become reality in our life time. The book therefore is a great source of condensed information for specialists involved in current and impending asteroid-related activities and a good starting point for space researchers, inventors, technologists and potential investors. Written for researchers, engineers, and businessmen interested in asteroids' exploration and exploitation.

    2015-01-01

    Protected areas are controversial because they are so important for conservation and because they distribute fortune and misfortune unevenly. The nature of that distribution, as well as the terrain of protected areas themselves, have been vigorously contested. In particular, the relationship between protected areas and poverty is a long-running debate in academic and policy circles. We review the origins of this debate and chart its key moments. We then outline the continuing flashpoints and ways in which further evaluation studies could improve the evidence base for policy-making and conservation practice. PMID:26460124

  9. Transparent meta-analysis of prospective memory and aging.

    Bob Uttl

    Full Text Available Prospective memory (ProM refers to our ability to become aware of a previously formed plan at the right time and place. After two decades of research on prospective memory and aging, narrative reviews and summaries have arrived at widely different conclusions. One view is that prospective memory shows large age declines, larger than age declines on retrospective memory (RetM. Another view is that prospective memory is an exception to age declines and remains invariant across the adult lifespan. The present meta-analysis of over twenty years of research settles this controversy. It shows that prospective memory declines with aging and that the magnitude of age decline varies by prospective memory subdomain (vigilance, prospective memory proper, habitual prospective memory as well as test setting (laboratory, natural. Moreover, this meta-analysis demonstrates that previous claims of no age declines in prospective memory are artifacts of methodological and conceptual issues afflicting prior research including widespread ceiling effects, low statistical power, age confounds, and failure to distinguish between various subdomains of prospective memory (e.g., vigilance and prospective memory proper.

    The future demands on professional archaeological prospection will be its ability to cover large areas in a time and cost efficient manner with very high spatial resolution and accuracy. The objective of the 2010 in Vienna established Ludwig Boltzmann Institute for Archaeological Prospection and Virtual Archaeology (LBI ArchPro) in collaboration with its eight European partner organisations is the advancement of state-of-the-art archaeological sciences. The application and specific further development of remote sensing, geophysical prospection and virtual reality applications, as well as of novel integrated interpretation approaches dedicated to non-invasive spatial archaeology combining near-surface prospection methods with advanced computer science is crucial for modern archaeology. Within the institute's research programme different areas for distinct case studies in Austria, Germany, Norway, Sweden and the UK have been selected as basis for the development and testing of new concepts for efficient and universally applicable tools for spatial, non-invasive archaeology. In terms of geophysical prospection the investigation of entire archaeological landscapes for the exploration and protection of Europe's buried cultural heritage requires new measurement devices, which are fast, accurate and precise. Therefore the further development of motorized, multichannel survey systems and advanced navigation solutions is required. The use of motorized measurement devices for archaeological prospection implicates several technological and methodological challenges. Latest multichannel Ground Penetrating Radar (GPR) arrays mounted in front off, or towed behind motorized survey vehicles permit large-scale GPR prospection surveys with unprecedented spatial resolution. In particular the motorized 16 channel 400 MHz MALÅ Imaging Radar Array (MIRA) used by the LBI ArchPro in combination with latest automatic data positioning and navigation solutions permits the reliable high

  20. Effects of aversive stimuli on prospective memory. An event-related fMRI study.

    Directory of Open Access Journals (Sweden)

    Massimiliano Rea

    Full Text Available Prospective memory (PM describes the ability to execute a previously planned action at the appropriate point in time. Although behavioral studies clearly showed that prospective memory performance is affected by the emotional significance attributed to the intended action, no study so far investigated the brain mechanisms subserving the modulatory effect of emotional salience on PM performance. The general aim of the present study was to explore brain regions involved in prospective memory processes when PM cues are associated with emotional stimuli. In particular, based on the hypothesised critical role of the prefrontal cortex in prospective memory in the presence of emotionally salient stimuli, we expected a stronger involvement of aPFC when the retrieval and execution of the intended action is cued by an aversive stimulus. To this aim BOLD responses of PM trials cued by aversive facial expressions were compared to PM trials cued by neutral facial expressions. Whole brain analysis showed that PM task cued by aversive stimuli is differentially associated with activity in the right lateral prefrontal area (BA 10 and in the left caudate nucleus. Moreover a temporal shift between the response of the caudate nucleus that preceded that of aPFC was observed. These findings suggest that the caudate nucleus might provide an early analysis of the affective properties of the stimuli, whereas the anterior lateral prefrontal cortex (BA10 would be involved in a slower and more deliberative analysis to guide goal-directed behaviour.

    1980-01-01

    In 1969-1979, exploratory and prospecting operations in Hrvatia were conducted at 34 districts which showed promise in terms of the likelihood of oil and gas. Definite advances were achieved both in the area of prospecting and in exploration. Prospecting techniques for non-anticlinal deposits and for testing fissured reservoirs were improved. A significant saving was attained by applying controlled-directional drilling. Discoveries which were made markedly increased the oil and gas reserves in categories A, B, and C. Over the 11-year period, 832 prospecting boreholes were drilled, of which 461 were vertical, 189 inclined, and 182 controlled-directional. The overall length (in meters) of these boreholes amounted to 1,318,272 m; 27.5% of the drilled boreholes were unsuccessful (in the United States, by comparison, in 1969 26.9% of all boreholes did not show positive results). This indicator may be considered acceptable, since Hrvatia deposits are small in size, irregular in shape, and have complicated geological structures. Through the use of controlled-directional drilling, it was possible to retain a large number of already drilled vertical boreholes for subsequent exploitation of producing levels; only 7.24% of the total number of boreholes were eliminated. During this period, a noticeable growth in oil and gas reserves was achieved; within the Pannonnsk basin of Hrvatian, these deposits, increased 51% (oil) and 26% (gas).

    The forest canopy chlorophyll content directly reflects the health and stress of forest. The accurate estimation of the forest canopy chlorophyll content is a significant foundation for researching forest ecosystem cycle models. In the present paper, the inversion of the forest canopy chlorophyll content was based on PROSPECT and SAIL models from the physical mechanism angle. First, leaf spectrum and canopy spectrum were simulated by PROSPECT and SAIL models respectively. And leaf chlorophyll content look-up-table was established for leaf chlorophyll content retrieval. Then leaf chlorophyll content was converted into canopy chlorophyll content by Leaf Area Index (LAD). Finally, canopy chlorophyll content was estimated from Hyperion image. The results indicated that the main effect bands of chlorophyll content were 400-900 nm, the simulation of leaf and canopy spectrum by PROSPECT and SAIL models fit better with the measured spectrum with 7.06% and 16.49% relative error respectively, the RMSE of LAI inversion was 0. 542 6 and the forest canopy chlorophyll content was estimated better by PROSPECT and SAIL models with precision = 77.02%.

    Quantification of spatially and temporally resolved water flows and water storage variations for all land areas of the globe is required to assess water resources, water scarcity and flood hazards, and to understand the Earth system. This quantification is done with the help of global hydrological models (GHMs). What are the challenges and prospects in the development and application of GHMs? Seven important challenges are presented. (1) Data scarcity makes quantification of human water use difficult even though significant progress has been achieved in the last decade. (2) Uncertainty of meteorological input data strongly affects model outputs. (3) The reaction of vegetation to changing climate and CO2 concentrations is uncertain and not taken into account in most GHMs that serve to estimate climate change impacts. (4) Reasons for discrepant responses of GHMs to changing climate have yet to be identified. (5) More accurate estimates of monthly time series of water availability and use are needed to provide good indicators of water scarcity. (6) Integration of gradient-based groundwater modelling into GHMs is necessary for a better simulation of groundwater-surface water interactions and capillary rise. (7) Detection and attribution of human interference with freshwater systems by using GHMs are constrained by data of insufficient quality but also GHM uncertainty itself. Regarding prospects for progress, we propose to decrease the uncertainty of GHM output by making better use of in situ and remotely sensed observations of output variables such as river discharge or total water storage variations by multi-criteria validation, calibration or data assimilation. Finally, we present an initiative that works towards the vision of hyper resolution global hydrological modelling where GHM outputs would be provided at a 1-km resolution with reasonable accuracy.

    As financial pressures drive health care to be more cost-effective and efficient, performing procedures outside the main operating room (MOR) is becoming more common. Pediatric sedation units (PSU) have proven both effective and safe at providing anesthesia for children. However, there is limited data available regarding the PSU and its potential application in pediatric otolaryngology. To evaluate the experience of performing pediatric outpatient procedures in a PSU through a parental satisfaction survey. Pediatric otolaryngology procedures performed in the PSU were prospectively recorded in a database. A prospective survey analysis was performed that measured parental satisfaction with scheduling/registration for surgery, nursing care, surgeon care, facility environment, timing/duration, and overall satisfaction. Parents completed this survey for outpatient procedures performed in either the PSU or in the MOR. The same attending surgeon was involved in all cases, with the only independent variable being the location of the surgery. Fifty surveys were collected for each group, and the surveys scores were statistically compared using nonparametric statistical analysis. Parental satisfaction was high in both the PSU and OR, with mean overall satisfaction scores of 4.8 and 4.9 (respectively) on an ordinal scale from 1 to 5. Parents reported greater clarity in preoperative information in the MOR (mean 4.8) compared to the PSU (mean 4.6) (pparents reported that MOR procedures started on time more often than those in the PSU (90-64%, pparent survey has identified education prior to surgery and timeliness of surgery as two areas to improve to meet the satisfaction standard provided by the OR.

    The Endut geothermal prospect is located in Banten Province, Indonesia. The geological setting of the area is dominated by quaternary volcanic, tertiary sediments and tertiary rock intrusion. This area has been in the preliminary study phase of geology, geochemistry, and geophysics. As one of the geophysical study, the gravity data measurement has been carried out and analyzed in order to understand geological condition especially subsurface fault structure that control the geothermal system in Endut area. After precondition applied to gravity data, the complete Bouguer anomaly have been analyzed using advanced derivatives method such as Horizontal Gradient (HG) and Euler Deconvolution (ED) to clarify the existance of fault structures. These techniques detected boundaries of body anomalies and faults structure that were compared with the lithologies in the geology map. The analysis result will be useful in making a further realistic conceptual model of the Endut geothermal area.

    GPR prospecting in areas of cultural interest can reveal interesting secrets of the past history of the probed monument. In particular, tombs and crypts under the floor of the churches can be revealed [1-2], but also tracks of past restorations and architectural changes occurred in the centuries, or features internal to the walls and the columns as cracks, metallic hinges, walled ciboria and hidden gaps [1, 3-5]. In this contribution, the case history of the church of the Humility in Parabita (Lecce, Italy) is proposed. The church of the Humility is a small and indeed not much well preserved church, deconsecrated many years ago and reused in other ways that have changed its original structure. Nowadays, it is undergoing a further transformation. However, before starting the works, a GPR prospecting has been committed to the Institute for Archaeological and Monumental Heritage IBAM-CNR. The prospecting has been performed with a pulsed Ris Hi-mode system equipped with a double antenna with central frequencies at 200 and 600 MHz, respectively. A first set of measures has been taken along two sets of B-scan, directed after the axis of the (unique) nave and along the orthogonal direction to this. The distance between the lines has been of the order of 40 cm, but some unmovable obstacles have not allowed a constant transect between any two adjacent lines. A second set of measures has been gathered in the area of the altar (not any longer present), here, due to the shape of the area to be prospected, the data have been gathered along a unique direction, but the interline spacing has been chosen equal to 30 cm. Please note that there is a step between the area of the altar and that of the nave, as usual in ancient churches, and this prevented from executing a unique C-scan including the entire floor of the church. The data have been processed according to a standard procedure based on zero timing, background removal, gain variable vs. the depth, one dimensional filtering

Therefore an appropriate thermal management is required for general lighting with LEDdies. One way to avoid overheating and shorter lifetime is the use of many small LED-dies on a large area heat sink (down to 70 μm edge length), so that heat can spread into a large area while at the same time light also appears on a larger area. The handling with such small LED-dies is very difficult because they are too small to be picked with common equipment. Therefore a new concept called collective transfer bonding using a temporary carrier chip was developed. A further benefit of this new technology is the high precision assembly as well as the plane parallel assembly of the LED-dies which is necessary for wire bonding. It has been shown that hundred functional LED-dies were transferred and soldered at the same time. After the assembly a cost effective established PCB-technology was applied to produce a large-area light source consisting of many small LED-dies and electrically connected on a PCB-substrate. The top contacts of the LED-dies were realized by laminating an adhesive copper sheet followed by LDI structuring as known from PCB-via-technology. This assembly can be completed by adding converting and light forming optical elements. In summary two technologies based on standard SMD and PCB technology have been developed for panel level LED packaging up to 610x 457 mm2 area size.

    On the basis of mineral-resource surveys the Selkirk Roadless Area, Idaho has little promise for the occurrence of mineral or energy resources. Molybdenum, lead, uranium, thorium, chromium, tungsten, zirconium, and several rare-earth elements have been detected in panned concentrates from samples of stream sediment, but no minerals containing the first five elements were found in place, nor were any conditions conducive to their concentration found. Zirconium, thorium, and the rare earths occur in sparsely disseminated accessory minerals in granitic rocks and no resource potential is identified. There is no history of mining in the roadless area and there are no oil, gas, mineral, or geothermal leases or current claims.

  15. Airborne geophysical prospecting for ultramafite associated talc, Altermark, northern Norway

    Science.gov (United States)

    Karlsen, Tor Arne; Olesen, Odleiv

    1996-10-01

    Talc-rich rocks in Altermark occur as rims around magnetite bearing serpentinite lenses which are up to about 1 km wide. The content of magnetite in the serpentinite makes magnetic measurements possible as a method for talc-prospecting. In 1991 a helicopter-borne geophysical survey combined with geological and petrophysical mapping was carried out in the Altermark area. Several positive magnetic anomalies were detected. Positive magnetic anomalies with oval shapes, well defined boundaries and smooth anomaly curves were interpreted to be caused by serpentinite lenses. Laboratory measurements revealed susceptibilities for the serpentinites between 0.006-0.36 SI and a Q-value of approximately 0.3. Magnetic modelling of the Nakkan anomaly and subsequent drilling revealed that it was indeed a serpentinite body surrounded by talc rocks which was the cause of the anomaly. The shallowest part was located about 150 m below surface. The geophysical exploration led to the discovery of a talc-carbonate deposit with an anticipated in situ tonnage of more than 1 million tons. The present study consequently proved to be a classical case study where we were able to locate and establish the three-dimensional form of serpentinite bodies associated with talc deposits. We conclude that helicopter-borne geophysical surveying is an effective tool in the exploration of serpentinite cored talc bearing rocks in complex geological areas where exposures are poor or absent and accessibility difficult. The rough topography and dense vegetation in the Altermark area make this type of survey very cost effective.

  16. A Prospect of Earthquake Prediction Research

    CERN Document Server

    Ogata, Yosihiko

    2013-01-01

    Earthquakes occur because of abrupt slips on faults due to accumulated stress in the Earth's crust. Because most of these faults and their mechanisms are not readily apparent, deterministic earthquake prediction is difficult. For effective prediction, complex conditions and uncertain elements must be considered, which necessitates stochastic prediction. In particular, a large amount of uncertainty lies in identifying whether abnormal phenomena are precursors to large earthquakes, as well as in assigning urgency to the earthquake. Any discovery of potentially useful information for earthquake prediction is incomplete unless quantitative modeling of risk is considered. Therefore, this manuscript describes the prospect of earthquake predictability research to realize practical operational forecasting in the near future.

    Literary data and own research results dedicated to bacteriocin investigations have been analysed. Bacteriocins as one of the most widespread factors of bacterial antagonism, which are distinguished by the majority of microorganisms and characterized by bactericidal action in respect of representatives of phylogenetically related species have been considered. Allowing for their high lytic activity and narrow action specificity, the prospects for the use of the bacteriocins as possible alternative antibacterial remedies are examined. The basic approaches to bacteriocin classification, their variety, structure, killer properties and mechanisms of lytic action are presented. The perspective trends of the use and possible significance of these antibacterial substances in medicine are indicated.

    An effective Lagrangian for the technidilaton and its interactions with matter is constructed. Properties of the technidilaton are compared with those of the Higgs boson. Technidilaton decays and production channels are investigated. Main technidilaton decays are suppressed compared to the Higgs boson and the most important production mechanism is due to gluon fusion. Prospects for technidilaton production and detection at $e^+e^-$ colliders and the SSC are examined. LEP 1, LEP 2 and SSC can find or rule out a technidilaton with a mass up to $10~GeV$, $40~GeV$ and $230~GeV$ respectively.

    2010-05-01

    Genetic Programming Applied to Base-Metal Prospectivity Mapping in the Aravalli Province, India Mineral prospectivity mapping of an area involves demarcation of potentially mineralized zones based on geologic features associated with the targeted mineral deposits. These features are sometimes directly observable and mapped; more often, their presence is inferred from their responses in various geoscience datasets, which are appropriately processed, generally in a GIS software environment, to derive their spatial proxies, also called predictor maps layers. Most approaches to mineral prospectivity mapping use mathematical models to approximate the relation between predictor map layers and the presence (or absence) of the targeted mineral deposits and to label unique combinations of spatially coincident predictor map layers as mineralized or barren. Essentially, the procedure involves recognizing and distinguishing the patterns of predictor map layers associated with mineralized locations from those associated with barren locations. Machine learning algorithms such as neural networks, support vector machines, and Bayesian classifiers are highly efficient pattern recognizers and classifiers. They are being increasingly applied to mineral prospectivity mapping, within or outside a GIS environment. However, most of these algorithms have a black-box-type implementation, that is, the output of these models do not generate new conceptual geological knowledge about the relative importance of various variables and their mutual relationships. Genetic Programming (GP) is a category of machine learning algorithms that address this problem effectively. In addition to generating the output classification map, GP also generates a set of rules that reveal the mutual relationships of the predictor variables, based on empirical analyses. These rules can be used to validate conceptual knowledge against empirical data, and also reveal new patterns in the data, resulting in new

    To ensure research and development programs focus on the most pressing environmental restoration and waste management problems at the U.S. Department of Energy (DOE), the Assistant Secretary for the Office of Environmental Management (EM) established a working group in August 1993 to implement a new approach to research and technology development. As part of this new approach, EM developed a management structure and principles that led to the creation of specific Focus Areas. These organizations were designed to focus the scientific and technical talent throughout DOE and the national scientific community on the major environmental restoration and waste management problems facing DOE. The Focus Area approach provides the framework for intersite cooperation and leveraging of resources on common problems. After the original establishment of five major Focus Areas within the Office of Technology Development (EM-50, now called the Office of Science and Technology), the Nuclear Materials Stabilization Task Group (EM-66) followed the structure already in place in EM-50 and chartered the Plutonium Focus Area (PFA). The following information outlines the scope and mission of the EM, EM-60, and EM-66 organizations as related to the PFA organizational structure.

    The US Department of Enregy (DOE) Subsurface Contaminants Focus Area is developing technologies to address environmental problems associated with hazardous and radioactive contaminants in soil and groundwater that exist throughout the DOE complex, including radionuclides, heavy metals; and dense non-aqueous phase liquids (DNAPLs). More than 5,700 known DOE groundwater plumes have contaminated over 600 billion gallons of water and 200 million cubic meters of soil. Migration of these plumes threatens local and regional water sources, and in some cases has already adversely impacted off-site rsources. In addition, the Subsurface Contaminants Focus Area is responsible for supplying technologies for the remediation of numerous landfills at DOE facilities. These landfills are estimated to contain over 3 million cubic meters of radioactive and hazardous buried Technology developed within this specialty area will provide efective methods to contain contaminant plumes and new or alternative technologies for development of in situ technologies to minimize waste disposal costs and potential worker exposure by treating plumes in place. While addressing contaminant plumes emanating from DOE landfills, the Subsurface Contaminants Focus Area is also working to develop new or alternative technologies for the in situ stabilization, and nonintrusive characterization of these disposal sites.

    Prospection is cognitive processes that involve constructing, encoding, and remembering the future. Less is known about the how these processes are evident in the prospective content of conversations. This study sought to identify and describe evidence of the prospective content in the conversations of friends as they transition to adulthood. The present secondary content analysis of the videotaped conversations of 15 young adult friendship dyads (n = 30, 16 females, 14 males, mean age = 21.3 years) in Canada examined these conversations based the following characteristics of prospection: simulation, reasoning about counterfactuals, constructing multiple possible futures, and episodic memory of the past. Four categories of prospective content were evident in these conversations, these processes were used sparingly in all but one conversation, and relatively few of them were collaborative in that dyad partners did not appear to serve to augment, clarify, or disconfirm prospective content.

    This study investigated prospective secondary science teachers' understandings of and intentions to teach about scientific modelling in the context of a model-based instructional module. Qualitative methods were used to explore the influence of instruction using dynamic computer modelling. Participants included 14 secondary science prospective teachers in the USA. Research questions included: (1) What do prospective teachers understand about models and modelling in science? (2) How do their understandings change, following building and testing dynamic computer models? and (3) What are prospective teachers' intentions to teach about scientific models? Scaffolds in the software, Model-IT, enabled participants to easily build dynamic models. Findings related to the process, content, and epistemological aspects of modelling, including: (a) prospective teachers became more articulate with the language of modelling; and (b) the module enabled prospective teachers to think critically about aspects of modelling. Still, teachers did not appear to achieve full understanding of scientific modelling.

  20. Prospects for Supersymmetry at the LHC & Beyond

    CERN Document Server

    AUTHOR|(CDS)2108556

    2015-01-01

    Run 1 of the LHC has provided three new motivations for supersymmetry: the need to stabilize the electroweak vacuum, the mass of the Higgs boson, and the fact that its couplings are Standard Model-like (so far). The prospects for discovering (and measuring) supersymmetry during future runs of the LHC are discussed in the frameworks of the constrained MSSM (CMSSM), models with non-universal soft supersymmetry-breaking contributions to Higgs masses (NUHM1,2) and the phenomenological MSSM with 10 arbitrary soft supersymmetry-breaking parameters (pMSSM10). In addition to the classic searches for missing transverse energy, searches for long-lived charged sparticles may also be promising. If supersymmetry does show up at the LHC, there are good prospects for measurements of the spectrum that can be compared with the indirect indications from other experiments. On the other hand, a higher-energy future circular proton-proton collider may be the best option for discovering supersymmetry if it does not appear at the L...

    1984-01-01

    This study compared two prospective pharmacokinetic dosing methods to predict steady-state concentrations of nortriptyline. One method required multiple determinations of the nortriptyline plasma concentration to estimate the drug's steady-state concentration. The second method required a single nortriptyline concentration drawn at a fixed time, preferably 36 hours, following a nortriptyline test dose. The 36-hour nortriptyline plasma concentrations (NTP 36h) were substituted into the straight-line equation of Cssav = 17.2 + 3.74 (NTP 36h), where Cssav is the average steady-state concentration for a 100 mg/day dose of nortriptyline. No differences were noted between the observed steady-state nortriptyline concentration of 121 +/- 19 ng/ml, the 36-hour single-point prediction mean concentration of 121 +/- 21 ng/ml, or the multiple-point prediction mean concentration of 122 +/- 19 ng/ml. Because of the similar findings between the two methods, the clinical advantages and disadvantages of each kinetic approach are discussed to put these prospective dosing protocols into their proper perspective.

  2. Expression of future prospective in indirect speech

    Directory of Open Access Journals (Sweden)

    Bodnaruk Elena Vladimirovna

    2015-03-01

    Full Text Available The article analyzes the characteristics and use of grammatical semantics and lexical and grammatical means used to create future prospects in double indirect discourse. The material for the study were epic works by contemporary German writers. In the analysis of the empirical material it has been pointed out that indirect discourse has preterial basis and is the kind of most frequent inner speech of characters. The most widely used form with future semantics in preterial indirect speech is conditional I, formally having a conjunctive basis, but is mostly used with the indicative semantics. Competitive to conditional I in indirect speech is preterial indicative. A characteristic feature of the indirect speech is the use of modal verbs, which, thanks to its semantics is usually referred as an action at a later term, creating the prospect of future statements. The most frequent were modal verbs wollen and sollen in the form of the preterite, more rare verbs were m ssen and k nnen. German indirect speech distinguishes the ability to use forms on the basis of conjunctive: preterite and plusquamperfect of conjunctive. Both forms express values similar to those of the indicative. However, conjunctive forms the basis of the data shown in a slightly more pronounced seme of uncertainty that accompanies future uses of these forms in indirect speech. In addition, plusquamperfect conjunctive differs from others by the presence of the seme of completeness.

  3. Refractory status epilepticus: a prospective observational study.

    2010-02-01

    Status epilepticus (SE) that is resistant to two antiepileptic compounds is defined as refractory status epilepticus (RSE). In the few available retrospective studies, estimated RSE frequency is between 31% and 43% of patients presenting an SE episode; almost all seem to require a coma induction for treatment. We prospectively assessed RSE frequency, clinical predictors, and outcome in a tertiary clinical setting. Over 2 years we collected 128 consecutive SE episodes (118 patients) in adults. Clinical data and their relationship to outcome (mortality and return to baseline clinical conditions) were analyzed. Twenty-nine of 128 SE episodes (22.6%) were refractory to first- and second-line antiepileptic treatments. Severity of consciousness impairment and de novo episodes were independent predictors of RSE. RSE showed a worse outcome than non-RSE (39% vs. 11% for mortality; 21% vs. 63% for return to baseline clinical conditions). Only 12 patients with RSE (41%) required coma induction for treatment. This prospective study identifies clinical factors predicting the onset of SE refractoriness. RSE appears to be less frequent than previously reported in retrospective studies; furthermore, most RSE episodes were treated outside the intensive care unit (ICU). Nonetheless, we confirm that RSE is characterized by high mortality and morbidity.

Findings revealed a visit timeframe mean of 40.3 min (range = 25–60; 43.6% of visits were ≤30-min timeframe. Visit and measurement times decreased as clinic staff gained measurement experience; measurement time mean was 17.9 min (range = 16.9–18.9. LBCQ symptoms and LVI were significantly (p < 0.001 correlated to LE referral; six of the nine patients referred (67% displayed both LBCQ symptoms/LVI. Visits with no symptoms reported did not result in referral, demonstrating the importance of using both indicators when assessing early LE. Lower threshold referral provides compelling evidence of potential cost savings over traditional threshold referral with reported costs of: $3755.00 and $6353.00, respectively (40.9% savings.

    In Malaysia, thorium exists in minerals and rare earth elements production residue. The average range of thorium content in Malaysian monazite and xenotime minerals was found about 70,000 and 15,000 ppm respectively. About 2,636 tonnes of Malaysian monazite was produced for a period of 5 years (2006-2010) and based on the above data, it can be estimated that Malaysian monazite contains about 184.5 tonnes of thorium. Although thorium can become a major radiological problem to our environment, but with the significant deposit of thorium in Malaysian monazite, it has a prospect as a future alternative fuel in nuclear technology. This paper will discuss the thorium issues in Malaysia especially its long term radiological risks to public health and environment at storage and disposal stages, the prospect of exploring and producing high purity thorium from our rare earth elements minerals for future thorium based reactor. This paper also highlights the holistic approach in thorium recovery from Malaysian rare earth element production residue to reduce its radioactivity and extraction of thorium and rare earth elements from the minerals with minimum radiological impact to health and environment.

    Full Text Available Background: It is desirable to have skilled midwives to provide competent care in hospital and community setting. Aims and Objectives: The objectives were to assess curriculum adequacy, preparedness and job preferences of prospective nurses. Materials and Methods: A descriptive survey was used for the study. Thestudy was carried out at nursing institutes in Ahmednagar District, Maharashtra, India. The participants were the 200 prospective Nurses(final year Nursing students of General Nursing and B.Sc Nursing Programme, who had undergone midwifery examination. A semi structured questionnaire with self report technique method was used. Results: 20.57% and 89.1% students respectively felt that, thetheory input and allotted clinical hours were adequate. During the clinical posting, 29.7% felt that they did not get the opportunity to work in midwifery sections. 33.1% students expressed that they did not get cases as per the requirement prescribed by Indian NursingCouncil.13.7% and 33.7% students respectively agreed that they lacked confidence to perform abdominal palpation of antenatal cases & conduct deliveries independently. A few (26.2% expressed their inability to resuscitate the newborn. 89.1% said that they needed more experience to work independently as midwives. Everyone felt the need of in-service education and majority (77.2% felt that its duration should be either three months or more. Conclusion: Present study reveals that only 7% of the prospective nurses are ready to work in midwifery section. Only 13.7% of the prospective nurses are ready to work in rural area. Since there is a shortfall of 70.02% forspeciality of obstetrics and gynecology in rural health (GOI, 1997, and there are only 40 qualified nurse midwives per 100,000 births inIndia or only one midwife for 2500 births in rural areas, it is imperative to strengthen midwifery training to bridge this gap.

    A new time-of-flight spectrometer for the chemical analysis of cosmic dust particles in space has been simulated by Simion 7.0. The instrument is based upon impact ionization. This method is a reliable method for in situ dust detection and is well established. Instruments using the impact ionization flew on board of Helios and Galileo and are still in operation on board of the Ulysses and Cassini-Huygens missions. The new instrument has a large sensitive area of 0.1m2 in order to achieve a significant number of measurements. The mass resolution M/{delta}M>100 and the mass range covers the most relevant elements expected in cosmic dust. The instrument has a reflectron configuration which increases the mass resolution. Most of the ions released during the impact are focused to the detector. The ion detector consists of a large area ion-to-electron converter, an electron reflectron and a microchannel plate detector.

    2011-10-01

    Full Text Available Circumpolar areas are associated with prolonged cold exposure where wind, precipitation, and darkness further aggravate the environmental conditions and the associated risks. Despite the climate warming, cold climatic conditions will prevail in circumpolar areas and contribute to adverse health effects. Frostbite is a freezing injury where localized damage affects the skin and other tissues. It occurs during occupational or leisure-time activities and is common in the general population among men and women of various ages. Industries of the circumpolar areas where frostbite occurs frequently include transportation, mining, oil, and gas industry, construction, agriculture, and military operations. Cold injuries may also occur during leisure-time activities involving substantial cold exposure, such as mountaineering, skiing, and snowmobiling. Accidental situations (occupational, leisure time often contribute to adverse cooling and cold injuries. Several environmental (temperature, wind, wetness, cold objects, and altitude and individual (behavior, health, and physiology predisposing factors are connected with frostbite injuries. Vulnerable populations include those having a chronic disease (cardiovascular, diabetes, and depression, children and the elderly, or homeless people. Frostbite results in sequelae causing different types of discomfort and functional limitations that may persist for years. A frostbite injury is preventable, and hence, unacceptable from a public health perspective. Appropriate cold risk management includes awareness of the adverse effects of cold, individual adjustment of cold exposure and clothing, or in occupational context different organizational and technical measures. In addition, vulnerable population groups need customized information and care for proper prevention of frostbites.

    2017-02-01

    Vehicle operation over paved and unpaved roads is an emission source that significantly contributes to air pollution. Emissions are derived from vehicle exhaust pipes and re-suspension of particulate matter generated by wind erosion and tire to road surface interactions. Environmental authorities require a methodology to evaluate road impact areas, which enable managers to initiate counter-measures, particularly under circumstances where historic meteorological and/or air quality data is unavailable. The present study describes an analytical and experimental work developed to establish a simplified methodology to estimate the area influenced by vehicular roads. AERMOD was chosen to model pollutant dispersion generated by two roads of common attributes (straight road over flat terrain) under the effects of several arbitrary chosen weather conditions. The resulting pollutant concentration vs. Distance curves collapsed into a single curve when concentration and distance were expressed as dimensionless numbers and this curve can be described by a beta distribution function. This result implied that average concentration at a given distance was proportional to emission intensity and that it showed minor sensitivity to meteorological conditions. Therefore, road influence was defined by the area adjacent to the road limited by distance at which the beta distribution function equaled the limiting value specified by the national air quality standard for the pollutant under consideration.

  16. Loads and loads and loads: The influence of prospective load, retrospective load, and ongoing task load in prospective memory

    Directory of Open Access Journals (Sweden)

    Beat eMeier

    2015-06-01

    Full Text Available In prospective memory tasks different kinds of load can occur. Adding a prospective memory task can impose a load on ongoing task performance. Adding ongoing task load can affect prospective memory performance. The existence of multiple target events increases prospective load and adding complexity to the to-be-remembered action increases retrospective load. In two experiments, we systematically examined the effects of these different types of load on prospective memory performance. Results showed an effect of prospective load on costs in the ongoing task for categorical targets (Experiment 2, but not for specific targets (Experiment 1. Retrospective load and ongoing task load both affected remembering the retrospective component of the prospective memory task. We suggest that prospective load can enhance costs in the ongoing task due to additional monitoring requirements. Retrospective load and ongoing task load seem to impact the division of resources between the ongoing task and retrieval of the retrospective component, which may affect disengagement from the ongoing task. In general, the results demonstrate that the different types of load affect prospective memory differentially.

    Previous studies have shown that leprosy multi-drug therapy (MDT) does not stop the progression of nerve function impairment. There are no prospective studies investigating the evolution of nerve anatomic abnormalities after treatment. We examined leprosy patients aiming to investigate the evolution of nerve ultrasonography (US) abnormalities and the risk factors for poor outcomes after MDT. We performed bilateral US of the ulnar (U), median (M) and common fibular (CF) nerves in 9 paucibacillary (PB) and 64 multibacillary (MB) patients before and after MDT. Forty-two patients had leprosy reactions (type 1, type 2, acute neuritis) during the study. We analyzed nerve maximum cross-sectional areas (CSA), echogenicity and Doppler signal. Poor outcomes included a post-treatment CSA above normal limits with a reduction of less than 30% (U, M) or 40% (CF) from the baseline, echogenicity abnormalities or intraneural Doppler in the post-treatment study. We found that PB and patients without reactions showed significant increases in CSA at CF, whereas MB and patients with reactions had CSA reduction in some nerves after treatment (p0.05) and in the patients with reactions compared to those without (66.7% and 38.7%; pleprosy classification were not significant risk factors for poor outcomes in CSA, echogenicity or Doppler. US nerve abnormalities can worsen after treatment despite the leprosy classification or the presence of reactions.

    Full Text Available Romania's trade in services has been severely hit by the global financial and economic crisis, and the negative consequences were still felt in 2012. This article aims to analyse the recent trends in Romania's services trade and assess its prospects. Relying on balance of payments statistics provided by the National Bank of Romania, it gives an overall picture on the dynamics, volume, composition and performance of the country’s trade in services over the crisis and post-crisis years. The analysis highlights a number of peculiarities of Romania's services trade, that seem to detache the country from the developments prevailing at the global and European level. The article concludes that: (1 along with a dramatic crisis-induced decline in the volume of services trade, Romania witnessed a sharp reversal of those favourable trends that have spurred the remarkable growth of its services flows in the pre-crisis period, contributing to rapid structural adjustment and improved performance; (2 the recovery of services trade is significantly delayed compared both to the country’s trade in goods and the trends shaping services flows globally and in the EU; (3 hence, Romania's traditional gap in the area of services trade has widened not only in relation to the old and new EU member states, but also to numerous developing countries.

  1. Prospects Of Microfinance Development In Uzbekistan: Issues And Solutions

    Full Text Available Rendering the microfinance services (in the form of microcredits, microloans, microleasing and others to the poor households, micro- and small businesses is still an important tool to reduce poverty as well as create more income generation and employment opportunities in countries with the developing and/or transition economies as Uzbekistan. Due to efforts of the Uzbek Government and international donors for the last 15 years, the microfinance sector could become a separate financial segment and address above-mentioned needs in progressive manner. On the other hand, the sector has relatively small share in the composition of financial mediation and its further development requires also consideration of such socio-economic and administrative factors as urbanization process along with uneven development of microfinance sector, acceleration of workforce growth due to increasing youth, the need for government’s transition away from costly poverty control methods, etc. Based on the sector development analysis by concurrent reviewing of these factors the paper reveals the lack of diversified sources of resources for microfinance institutions (MFIs, stiffness of regulatory framework, the need for improving the sector infrastructure in terms of covering credit risks, building up sector’s capacity in covering operational risks. Beside quantitative indicators for prospective development of the sector the paper also discusses qualitative areas to be stressed on to fill the identified gaps.

    Objectives. We investigated prospective associations among assets (e.g., family communication), which research has shown to protect youths from risk behavior, and successful transition to early adulthood (STEA). Methods. We included participants (n = 651) aged 18 years and older at study wave 5 (2007-2008) of the Youth Asset Study, in the Oklahoma City, Oklahoma, metro area, in the analyses. We categorized 14 assets into individual-, family-, or community-level groups. We included asset groups assessed at wave 1 (2003-2004) in linear regression analyses to predict STEA 4 years later at wave 5. Results. Individual- and community-level assets significantly (P assets participants possessed the better the STEA outcome. There was a gender interaction for family-level assets suggesting that family-level assets were significant predictors of STEA for males but not for females. Conclusions. Public health programming should focus on community- and family-level youth assets as well as individual-level youth assets to promote positive health outcomes in early adulthood.

    During the period from 1.1 to 31.12.90, 86 injuries associated with paragliding were analysed in a prospective study in 12 different Swiss hospitals with reference to causes, patterns, and frequencies. Spine injuries (36%) and lesions of the lower extremities (35%) were diagnosed most frequently. Surprisingly no neurological complications occurred, which is possibly explained by the solitary axial trauma. In 15 cases very severe malleolar fractures required surgical intervention. One accident was fatal due to a lung rupture. 60% of all accidents happened during the landing phase, 26% at launching and 14% at flight. Half of the pilots were affected in their primary training course. Most accidents were due to an in-flight error of judgement, such as incorrect estimation of wind conditions and a choice of unfavourable landing sites. In contrast to early reports of hang-gliding injuries, only one accident was due to an equipment failure, namely a ruptured steering line. In more than a third of all accidents, the used paraglider was not in correct correlation with the pilot's weight and experience. Inspired by the desire for a long flight, gliders of too large surface-areas were often used, leading to a more unstable flight. To reduce the frequency of paragliding injuries, an accurate choice of equipment and increased attention to environmental factors is mandatory. Furthermore education-programs should focus more on intensifying the pilot's mental and practical skills.

    Approximately 440 million people globally are afflicted by hookworm disease, one of the 17 WHO-recognized neglected tropical diseases (NTDs). The iron-deficiency anaemia attributed to this disease contributes to at least 3.2 million disability-adjusted life years (DALYs) according to the Global Burden of Disease Study 2010. The current WHO-recommended control strategies rely primarily on mass drug administration or preventive chemotherapy. However, evidence is starting to accumulate confirming that preventive chemotherapy alone will not be sufficient to reduce the reinfection rates of hookworm, especially in areas of heavy transmission. The global health and research community is currently building a consensus stressing the need for the advancement of research and innovation to bridge the gaps and identify new public health interventions for diseases such as hookworm and other NTDs. This paper presents the strategies used by the Sabin Vaccine Institute Product Development Partnership (Sabin PDP) in their ongoing endeavour for the development of a human hookworm vaccine. Recent updates and the current prospects for success of an effective human hookworm vaccine, as a new technology to be linked to or combined with drug interventions, are presented.

    Full Text Available The article is aimed to identify the models of financial equalization applied in foreign countries, and to substantiate the possibilities for use of foreign experience in terms of financial equalization or individual elements of such models on the territory of Ukraine, for taking into consideration the foreign tools of financial equalization in the context of the State regional policy reforms is a priority and urgent task of the present day. During the generalization and systematization of scientific works by numerous domestic and foreign scientists, models of financial equalization, depending on the form of state structure in the country, have been identified. Determinants of the necessity of financial equalization were analyzed, such as: the imbalance between the own financial security and the level of assigned tasks; the level of fiscal decentralization. Methods of income and expenditures equalization, applied in vertical or horizontal levels for balancing regional development, have been substantiated. Features of expansion of financial security of budgets by using innovative tools for equalization have been determined. A comparison of the models of financial equalization in foreign countries was made and the major tasks for improving the mechanism and organization of financial equalization of budgets in Ukraine were defined. Prospects for further research in this area are diversification of tools for financial equalization, defining the investment component in the structure of budgets' incomes and studying the activities of sub-central authorities in the financial market

  6. Modeling Adversaries in Counterterrorism Decisions Using Prospect Theory.

    2016-04-01

    Counterterrorism decisions have been an intense area of research in recent years. Both decision analysis and game theory have been used to model such decisions, and more recently approaches have been developed that combine the techniques of the two disciplines. However, each of these approaches assumes that the attacker is maximizing its utility. Experimental research shows that human beings do not make decisions by maximizing expected utility without aid, but instead deviate in specific ways such as loss aversion or likelihood insensitivity. In this article, we modify existing methods for counterterrorism decisions. We keep expected utility as the defender's paradigm to seek for the rational decision, but we use prospect theory to solve for the attacker's decision to descriptively model the attacker's loss aversion and likelihood insensitivity. We study the effects of this approach in a critical decision, whether to screen containers entering the United States for radioactive materials. We find that the defender's optimal decision is sensitive to the attacker's levels of loss aversion and likelihood insensitivity, meaning that understanding such descriptive decision effects is important in making such decisions.

    2016-04-01

    The origin of the highest energy cosmic rays at ˜1020 eV is still unknown. Ultra-high energy neutrinos from the GZK process should provide information on the sources and their properties. A promising and cost effective method for observing GZK-neutrinos is based on detection of Askaryan radio pulses with antennas installed in ice. The ARIANNA project aims at instrumenting a 36*36 km2 large area on the Ross Ice Shelf with an array of radio detection stations. The deployment of a test system for ARIANNA, the Hexagonal Radio Array (HRA), was completed in December 2014. The three first stations were installed in 2012. Solar panels are used to drive the < 10 W stations. The system hibernated at sunset in April and all stations returned to operation in September. The site is essentially free of anthropogenic noise. Simple cuts eliminate background and provides for efficient selection of neutrino events. Prospects for the sensitivity of the full ARIANNA array to the flux of GZK neutrinos are shown.

The author connects the need to modernize the Russian economy with the task of doubling GDP, correcting structural imbalances, reducing the technological gap with the developed world, overcoming social polarization in income, fighting inflation and smoothing the growth of inter-regional contrasts. The aim of modernizing the Russian economy is to achieve high competitiveness of the national economy, which would put the Russian Federation in terms of living standards among the most developed countries, and would provide a decent position in the world. The fact that "breakthrough" sectors of the sixth technological structure cannot be the starting point of modernization is substantiated. The concept of national competitiveness is reviewed. The lack of a complete model of modernization in the world is highlighted. Two main areas in relation to the modernization of the Russian Federation are identified: modernization of the commodity sector, which should represent applied modernization based on the comparative advantages of the Russian economy; with respect to functionally interrelated industries (fuel and energy complex and the oil-gas and upgrading of transport infrastructure, which is so effective because of unique transit facilities and prospects of Russia.

    Full Text Available As a recent phenomenon, the BRICS continues to provoke heated discussions about its prospects and its sustainability asa community of like-minded actors. While observers can recognize common goals regarding international financial andeconomic architecture reform, the BRICS security agenda occupies a grey area of uncertainty. Meanwhile, as host of theBRICS in 2015–16, Russia sees as its main priority the transformation of the group from a loose forum into a full-fledgedmechanism for economic and political coordination and cooperation. Peace and security issues are thus included, and atleast lead to a limited conversion at the level of lowest common denominator. This limited conversion derives from a varietyof factors – geographical and geopolitical positions, diverse political historic tradition, different international political statuswithin current political governance system, close economic and political ties and complicated form of cooperation/competitionwith the established western powers, as well as differences in understanding and promoting their own global ambitionsand priorities. In this article, the evolution of Russia’s approaches toward the importance of the BRICS and its place withinRussian foreign policy priorities is considered, with attention given to political security, international law and global governance.While a number of problems would receive only minor attention and are more relevant to only some participants (suchas fighting illegal drugs or maritime security or certain regional conflicts, other issues need to be handled at the lowest commondenominator (such as reform of the United Nations Security Council or non-proliferation.

    2010-01-01

    Although the application of ultrasonic energy to produce or to enhance a wide variety of processes have been explored since about the middle of the 20th century, only a reduced number of ultrasonic processes have been established at industrial level. However, during the last ten years the interest in ultrasonic processing has revived particularly in industrial sectors where the ultrasonic technology may represent a clean and efficient tool to improve classical existing processes or an innovation alternative for the development of new processes. Such seems to be the case of relevant sectors such as food industry, environment, pharmaceuticals and chemicals manufacture, machinery, mining, etc where power ultrasound is becoming an emerging technology for process development. The possible major problem in the application of high-intensity ultrasound on industrial processing is the design and development of efficient power ultrasonic systems (generators and reactors) capable of large scale successful operation specifically adapted to each individual process. In the area of ultrasonic processing in fluid media and more specifically in gases, the development of the steppedplate transducers and other power ge with extensive radiating surface has strongly contributed to the implementation at semi-industrial and industrial stage of several commercial applications, in sectors such as food and beverage industry (defoaming, drying, extraction, etc), environment (air cleaning, sludge filtration, etc...), machinery and process for manufacturing (textile washing, paint manufacture, etc). The development of different cavitational reactors for liquid treatment in continuous flow is helping to introduce into industry the wide potential of the area of sonochemistry. Processes such as water and effluent treatment, crystallization, soil remediation, etc have been already implemented at semi-industrial and/or industrial stage. Other single advances in sectors like mining or energy have

  13. Prospects for Precision Neutrino Cross Section Measurements

    Energy Technology Data Exchange (ETDEWEB)

    Harris, Deborah A. [Fermilab

    2016-01-28

    The need for precision cross section measurements is more urgent now than ever before, given the central role neutrino oscillation measurements play in the field of particle physics. The definition of precision is something worth considering, however. In order to build the best model for an oscillation experiment, cross section measurements should span a broad range of energies, neutrino interaction channels, and target nuclei. Precision might better be defined not in the final uncertainty associated with any one measurement but rather with the breadth of measurements that are available to constrain models. Current experience shows that models are better constrained by 10 measurements across different processes and energies with 10% uncertainties than by one measurement of one process on one nucleus with a 1% uncertainty. This article describes the current status of and future prospects for the field of precision cross section measurements considering the metric of how many processes, energies, and nuclei have been studied.

    Liem, André; Brangier, Eric

    2012-01-01

    In this conceptual article the topic of "Prospective Ergonomics" will be discussed within the context of innovation, design thinking and design processes & methods. Design thinking is essentially a human-centred innovation process that emphasises observation, collaboration, interpretation, visualisation of ideas, rapid concept prototyping and concurrent business analysis, which ultimately influences innovation and business strategy. The objective of this project is to develop a roadmap for innovation, involving consumers, designers and business people in an integrative process, which can be applied to product, service and business design. A theoretical structure comprising of Innovation perspectives (1), Worldviews supported by rationalist-historicist and empirical-idealistic dimensions (2) and Models of "design" reasoning (3) precedes the development and classification of existing methods as well as the introduction of new ones.

  16. PROSPECT - A precision oscillation and spectrum experiment

    2015-01-01

    Segmented antineutrino detectors placed near a compact research reactor provide an excellent opportunity to probe short-baseline neutrino oscillations and precisely measure the reactor antineutrino spectrum. Close proximity to a reactor combined with minimal overburden yield a high background environment that must be managed through shielding and detector technology. PROSPECT is a new experimental effort to detect reactor antineutrinos from the High Flux Isotope Reactor (HFIR) at Oak Ridge National Laboratory, managed by UT Battelle for the U.S. Department of Energy. The detector will use novel lithium-loaded liquid scintillator capable of neutron/gamma pulse shape discrimination and neutron capture tagging. These enhancements improve the ability to identify neutrino inverse-beta decays and reject background events in analysis. Results from these efforts will be covered along with their implications for an oscillation search and a precision spectrum measurement.

    2013-05-01

    Full Text Available Cultured meat, or in vitro meat, is one of the ideas that are being proposed to help solve the problems associated with the ever-growing global meat consumption. The prospect may bring benefit for the environment, climate, and animal ethics, but has also generated doubts and criticism. A discussion of the possible environmental benefit and of animal ethics issues in relation to cultured meat production will be given. A perceived 'unnaturalness' of cultured meat may be one of the strongest barriers for public acceptance. This will be discussed and rejected. As to our relations with nature and animals, it is plausible that cultured meat will lead to improvement rather than to deterioration. The issue of public acceptance and some of the problems of introducing this new product on the market will also be discussed.http://dx.doi.org/10.5324/eip.v7i1.1788

    Guerard, Bruno; Murtas, Fabrizio

    2014-01-01

    Compared to Multi Wires Proportional Chambers (MWPC), Micro-Pattern Gas Detectors (MPGD) used in HEP to detect MIPs offer better spatial resolution, counting rate capability, and radiation hardness; their fabrication is also more reproducible. Provided similar advantages are applicable to detect neutrons, MPGDs might contribute significantly to the development of neutron scientific instrumentation. In order to evaluate the prospects of neutron MPGDs, it is worth knowing the applications which would benefit from a gain in performance, and if they offer a competitive alternative to conventional 3He detectors. These questions have been at the focus of the workshop "Neutron Detection with Micro-Pattern Gaseous Detectors" organized by RD51 in collaboration with HEPTech, which took place at CERN on October 14-15, 2013. The goal of this workshop was to help disseminating MPGD technologies beyond High Energy Physics, and to give the possibility to academic institutions, potential users and industry to meet together. ...

  3. Development and Prospect of Nanoarchitectured Solar Cells

    Bo Zhang

    2015-01-01

    Full Text Available This paper gives an overview of the development and prospect of nanotechnologies utilized in the solar cell applications. Even though it is not clearly pointed out, nanostructures indeed have been used in the fabrication of conventional solar cells for a long time. However, in those circumstances, only very limited benefits of nanostructures have been used to improve cell performance. During the last decade, the development of the photovoltaic device theory and nanofabrication technology enables studies of more complex nanostructured solar cells with higher conversion efficiency and lower production cost. The fundamental principles and important features of these advanced solar cell designs are systematically reviewed and summarized in this paper, with a focus on the function and role of nanostructures and the key factors affecting device performance. Among various nanostructures, special attention is given to those relying on quantum effect.

    We describe a prospective study of histidinaemia. Probands and siblings (n = 21) with typical histidinaemia in 16 families were ascertained by newborn screening; diagnosis was confirmed by appropriate investigations in each subject; none had been treated by low histidine diet. The median age of subjects with histidinaemia was 9.5 y (mean 10.0, SD 3.5, range 6-18). Age-matched sib-pairs and their mothers were studied. IQ scores (Full Scale, Verbal and Performance Scores), Visual-Motor Integration Performance (Bender Gestalt and Koppitz scores), Wide Range Achievement Test (Reading and Mathematics), school performance, and psychological history were evaluated, as well as the medical history (pregnancy, delivery, neonatal, post-natal development). Findings were correlated with biochemical phenotype. CNS development in histidinaemic subjects (mean and distribution of scores) was normal; outlier values did not correlate with degree of histidinaemia. We can conclude that histidinaemia detected by newborn screening is a non-disadaptive phenotype.

    2013-09-04

    Knowledge of spider bites in Central Europe derives mainly from anecdotal case presentations; therefore we aimed to collect cases systematically. From June 2011 to November 2012 we prospectively collected 17 cases of alleged spider bites, and together with two spontaneous notifications later on, our database totaled 19 cases. Among them, eight cases could be verified. The causative species were: Cheiracanthium punctorium (3), Zoropsis spinimana (2), Amaurobius ferox, Tegenaria atrica and Malthonica ferruginea (1 each). Clinical presentation was generally mild, with the exception of Cheiracanthium punctorium, and patients recovered fully without sequelae. In Switzerland, spider bites generally have a benign clinical course, which is characterised by minor effects, with rapid and complete recovery. Since only verified spider bites can be regarded as spider bites, in the case of clinically important arachnidism, the spider should be sent to an expert for identification. Our study may help to diminish spider fear and reassure people who have experienced a bite.

    A medium term view of the prospects for oil production in continental Europe, focusing on the offshore production in UK and Norwegian waters, is presented. The paper begins with a recent history and an overview of current oil production and recent trends. The growth of North Sea production has been important, contributing more than two-thirds of the growth in non OPEC oil production. The development of the Andrew field in the UK North Sea is presented as an example of new management methods succeeding in enhancing the economic viability of oil fields that would otherwise be marginal or non economic The Foinaven field in the new West of Shetlands province illustrates the way in which the combination of technological advances and changes in industry practices is extending the frontiers of commercial viability. Supply projections show North Sea production continuing to grow, but not as rapidly as over the past five years. (author). 7 figs., 8 refs.

    CERN Document Server

    2013-01-01

    The Earth has limited material and energy resources while these resources in space are virtually unlimited. Further development of humanity will require going beyond our planet and exploring of extraterrestrial resources and sources of unlimited power.   Thus far, all missions to asteroids have been motivated by scientific exploration. However, given recent advancements in various space technologies, mining asteroids for resources is becoming ever more feasible. A significant portion of asteroids value is derived from their location; the required resources do not need to be lifted at a great expense from the surface of the Earth.   Resources derived from Asteroid not only can be brought back to Earth but could also be used to sustain human exploration of space and permanent settlements in space.   This book investigates asteroids' prospective energy and material resources. It is a collection of topics related to asteroid exploration, and utilization. It presents past and future technologies and solutions t...

  13. HIGH ENERGY POLARIZATION OF BLAZARS: DETECTION PROSPECTS

    Emission from blazar jets in the ultraviolet, optical, and infrared is polarized. If these low-energy photons were inverse-Compton scattered, the upscattered high-energy photons retain a fraction of the polarization. Current and future X-ray and gamma-ray polarimeters such as INTEGRAL-SPI, PoGOLITE, X-Calibur, Gamma-Ray Burst Polarimeter, GEMS-like missions, ASTRO-H, and POLARIX have the potential to discover polarized X-rays and gamma-rays from blazar jets for the first time. Detection of such polarization will open a qualitatively new window into high-energy blazar emission; actual measurements of polarization degree and angle will quantitatively test theories of jet emission mechanisms. We examine the detection prospects of blazars by these polarimetry missions using examples of 3C 279, PKS 1510-089, and 3C 454.3, bright sources with relatively high degrees of low-energy polarization. We conclude that while balloon polarimeters will be challenged to detect blazars within reasonable observational times (with X-Calibur offering the most promising prospects), space-based missions should detect the brightest blazars for polarization fractions down to a few percent. Typical flaring activity of blazars could boost the overall number of polarimetric detections by nearly a factor of five to six purely accounting for flux increase of the brightest of the comprehensive, all-sky, Fermi-LAT blazar distribution. The instantaneous increase in the number of detections is approximately a factor of two, assuming a duty cycle of 20% for every source. The detectability of particular blazars may be reduced if variations in the flux and polarization fraction are anticorrelated. Simultaneous use of variability and polarization trends could guide the selection of blazars for high-energy polarimetric observations.

  14. MARICULTURE DEVELOPMENT IN INDONESIA: Prospects and Constraints

    Directory of Open Access Journals (Sweden)

    Michael A. Rimmer

    2010-12-01

    Full Text Available Mariculture is an important component of Indonesian fisheries and aquaculture production, directly contributing an estimated US$ 320 million in 2008. Because most mariculture production is focussed on producing for export markets, mariculture production is an important source of foreign earnings for the Indonesian economy. This paper reviews the current status and prospects for continuing development of mariculture in Indonesia. Currently the major mariculture commodity in Indonesia is seaweed for carrageenan production. Seaweed production accounts for 98% of total Indonesian mariculture production and 84% of value. The other major commodity groups are marine finfish and pearl oysters. Commodities being developed for mariculture in Indonesia include abalone and spiny lobsters. Prospects for continued development of mariculture in Indonesia appear positive. Indonesia has several advantages for mariculture development, including many potential mariculture sites, a stable tropical climate, and does not suffer from cyclonic storms. The Government of Indonesia is planning to increase aquaculture production substantially over the next four years, including mariculture production. Globally, demand for seafood products is expanding due to increasing population and increased per capita consumption of fish products. Constraints to the continued development of mariculture in Indonesia include: limited seed supply, particularly of species which cannot be economically produced in hatcheries, such as spiny lobsters; need to develop more efficient production systems for some marine finfish; the need to improve environmental sustainability by improving feeds and reducing environmental impacts; and market issues relating to environmental sustainability.

    2017-04-01

    This paper reviewed some specific conceptions of hydrological experimental areas (catchments) while found that the traditional definition of 'catchment' may be difficult to meet in plain areas. According to the review of development history and current situation of hydrological experimental areas (catchments) in plain areas in China, 4 stages were shown besides the recent 10 years, i.e., 'golden stage(1952-1966)', 'backward stage(1966-1986)', 'short recovery stage(1986-1989)' and 'stagnant stage(1986-2006)'. It gets new impetus since 2006 with some investigation work promoted by the government. Furthermore, some historic problems during establishing experimental areas (catchments) in plain areas were revealed based on the document literature and a few meaningful lessons were drawn from the past. It was also the first time to collect and classify the details of both 11 representative experimental areas in China and abroad, after that a brief comparison about the measurement level and research directions was made between two regions. Additionally, we took the experimental research work in the plain of Taihu Lake Basin as example and introduced the particular research goals and the corresponding establishing process, including how to design the experimental area, eg, size, location, land use type, arranging the measurement instruments et al. We hope such case can provide a reference for newly-building, recovering and extending hydrological experimental areasin plain areas in the future. Finally, this paper prospected the future development in establishment and research in hydrological experimental areas (catchments) in plain areas. It may be more common to see the cooperation between model scientists and field experts. Because of the comprehensive goals in water problems, researchers from various fields would work together in the future experimental research work. Scale study and modelling in plain areas will be a promising branch after some typical experimental areas
