    1996-06-01

    This summary gives the major points of the Draft Environmental Impact Statement (EIS) prepared for the Nez Perce Tribal Hatchery by the Nez Perce Tribe (NPT), the Bonneville Power Administration (BPA), the Bureau of Indian Affairs (BIA), and other interested parties. The Nez Perce once were one of the largest Plateau tribes in the Northwest and occupied a territory that included north central Idaho, southeastern Washington and northeastern Oregon. Salmon and other migratory fish species are an invaluable food resource and an integral part of the Nez Perce Tribe`s culture. Anadromous fish have always made up the bulk of the Nez Perce tribal diet and this dependence on salmon was recognized in the treaties made with the Tribe by the US. The historic economic, social, and religious significance of the fish to the Nez Perce Tribe continues to this day, which makes the decline of fish populations in the Columbia River Basin a substantial detrimental impact to the Nez Perce way of life. The Nez Perce Tribal Hatchery is a supplementation program that would rear and release spring, summer, and fall chinook (Oncorhynchus tshawytscha), biologically similar to wild fish, to reproduce in the Clearwater River Subbasin. Program managers propose techniques that are compatible with existing aquatic and riparian ecosystems and would integrate hatchery-produced salmon into the stream and river environments needed to complete their life cycle.

    1996-08-01

    The Nez Perce Tribe has proposed to build and operate the Nez Perce Tribal Hatchery (NPTH) in the Clearwater River subbasin of Idaho for the purpose of restoring self-sustaining populations of spring, summer, and fall chinook salmon to their native habitats. The project comprises a combination of incubation and rearing facilities, satellite rearing facilities, juvenile and adult collection sites, and associated production and harvest management activities. As currently conceived, the NPTH program will produce approximately 768,000 spring chinook parr, 800,000 summer chinook fry, and 2,000,000 fall chinook fry on an annual basis. Hatchery fish would be spawned, reared, and released under conditions that promote wild-type characteristics, minimize genetic changes in both hatchery and wild chinook populations, and minimize undesirable ecological interactions. The primary objective is to enable hatchery-produced fish to return to reproduce naturally in the streams in which they are released. These and other characteristics of the project are described in further detail in the Nez Perce Tribal Hatchery Master Plan, the 1995 Supplement to the Master Plan, and the Nez Perce Tribal Hatchery Program Environmental Impact Statement. The report in hand is referred to in project literature as the NPTH Monitoring and Evaluation (M&E) Plan. This report describes monitoring and evaluation activities that will help NPTH managers determine whether they were successful in restoring chinook salmon populations and avoiding adverse ecological impacts.

    Johnson, David B.; Larson, Roy Edward; Walker, Grant W.

    2001-08-17

    This report consists of activities/events conducted in response to the Objectives and Tasks described in the 1999 contract Statement Of Work for the Planning and Planning and Design (P and D) and Maintenance (O and M) activities of the Nez Perce Tribal Hatchery (NPTH). The report follows the format of the contract for ease in finding accomplishments. Although specific emphasis will be placed on activities related directly to the NPTH, activities from other artificial production related projects might also be noted because of overlap in staff duties and production facilities. Additionally, the project leader's role has evolved as other Tribal fisheries projects have been developed and assigned to the Production Division, Department of Fisheries Resource Management (DFRM), and Nez Perce Tribe (NPT). Thus, implementation of the project leader role for the NPTH actually entails specific duties of the Production Division Director and the Production Division Coordinator, as well as the Hatchery Division Coordinator.

    1992-04-01

    In 1984, the Nez Perce National forest and the Bonneville Power Administration entered into a contractual agreement which provided for improvement of spring chinook salmon and summer steelhead trout habitat in south Fork Clearwater River tributaries. Project work was completed in seven main locations: Crooked River, Red River, Meadow Creek Haysfork Gloryhole, Cal-Idaho Gloryhole, Fisher Placer and Leggett Placer. This report describes restoration activities at each of these sites.

    United States. Bonneville Power Administration; Nez Perce Tribal Hatchery (Idaho).

    1996-06-01

    Bonneville Power Administration, the Bureau of Indian Affairs, the Nez Perce Tribe propose a supplementation program to restore chinook salmon to the Clearwater River Subbasin in Idaho. The Clearwater River is a tributary to the Snake River, which empties into the Columbia River. The Nez Perce Tribe would build and operate two central incubation and rearing hatcheries and six satellite facilities. Spring, summer and fall chinook salmon would be reared and acclimated to different areas in the Subbasin and released at the hatchery and satellite sites or in other watercourses throughout the Subbasin. The supplementation program differs from other hatchery programs because the fish would be released at different sizes and would return to reproduce naturally in the areas where they are released. Several environmental issues were identified during scoping: the possibility that the project would fail if mainstem Columbia River juvenile and adult passage problems are not solved; genetic risks to fish listed as endangered or threatened; potential impacts to wild and resident fish stocks because of increase competition for food and space; and water quality. The Proposed Action would affect several important aspects of Nez Perce tribal life, primarily salmon harvest, employment, and fisheries management.

    1992-03-01

    This report describes the findings that have resulted from the effort to create a proposed Nez Perce Tribal Hatchery (NPTH) in northern Idaho. This effort has been undertaken because of low population densities of salmon in the Clearwater and Salmon River Basins. The Northwest Power Planning Council (Council) has approved the NPTH concept. For the NPTH to proceed, the Council must approve a master plan and amend the Columbia Basin Fish and Wildlife Program (CBFWP). Requirements of the National Environmental Policy Act (NEPA) also must be met. The goals of NPTH are to: (1) develop, increase, and reintroduce natural populations of spring, summer, and fall chinook in the Clearwater and Salmon River Basins; (2) sustain long-term preservation and genetic integrity of target fish populations; (3) keep the ecological and genetic impacts of nontarget fish populations within acceptable limits; and, (4) provide harvest opportunities for both tribal and non-tribal anglers.

    The Nez Perce Tribal Hatchery (NPTH) responds directly to a need to mitigate for naturally-reproducing salmon in the Clearwater River subbasin. The overall goal is to produce and release fish that will survive to adulthood, spawn in the Clearwater River subbasin and produce viable offspring that will support future natural production and genetic integrity. Several underlying purposes of fisheries management will be maintained through this program: (1) Protect, mitigate, and enhance Columbia River subbasin anadromous fish resources. (2) Develop, reintroduce, and increase natural spawning populations of salmon within the Clearwater River subbasin. (3) Provide long-term harvest opportunities for Tribal and non-Tribal anglers within Nez Perce Treaty lands within four generations (20 years) following project completion. (4) Sustain long-term fitness and genetic integrity of targeted fish populations. (5) Keep ecological and genetic impacts to non-target populations within acceptable limits. (6) Promote Nez Perce Tribal Management of Nez Perce Tribal hatchery Facilities and production areas within Nez Perce Treaty lands. Nez Perce Tribal Hatchery is a supplementation program that will rear and release spring, fall, and early-fall stocks of chinook salmon. Two life stages of spring chinook salmon will be released: parr and presmolts. Fall and early-fall chinook salmon will be released as subyearling smolts. The intent of NPTHC is to use conventional hatchery and Natural Rearing Enhancement Systems (NATURES) techniques to develop, increase and restore natural populations of spring and fall chinook salmon in the Clearwater River subbasin.

    This report fulfills the contract obligations based on the Statement of Work (SOW) for the project as contracted with Bonneville Power Administration (BPA). Nez Perce Tribal Hatchery (NPTH) Year-2001 annual report combines information from two contracts with a combined value of $2,336,491. They are identified by Bonneville Power Administration as follows: (1) Operations and Maintenance--Project No. 1983-350-00, Contract No. 4504, and (2) Planning and Design--Project No. 1983-350-00, Contract No. 4035. The Operations and Maintenance (O&M) budget of $2,166,110 was divided as follows: Facility Development and Fish Production Costs--$860,463; and Equipment Purchases as capital cost--$1,305,647 for equipment and subcontracts. The Planning and Design (P&D) budget of $170,381 was allocated to development of a Coho master planning document in conjunction with Nez Perce Tribal Hatchery. The O&M budget expenditures represent personnel and fish production expenses; e.g., administration, management, coordination, facility development, personnel training and fish production costs for spring Chinook and Coho salmon. Under Objective 1: Fish Culture Training and Education, tribal staff worked at Clearwater Anadromous Hatchery (CAFH) an Idaho Department of Fish and Game (IDFG) facility to produce spring Chinook smolt and parr for release that are intended to provide future broodstock for NPTH. As a training exercise, BPA allowed tribal staff to rear Coho salmon at Dworshak National Fish Hatchery, a U.S. Fish and Wildlife Service (USFWS) facility. This statement of work allows this type of training to prepare tribal staff to later rear salmon at Nez Perce Tribal Hatchery under Task 1.6. As a subset of the O&M budget, the equipment purchase budget of $1,305,647 less $82,080 for subcontracts provides operational and portable equipment necessary for NPTH facilities after construction. The equipment budget for the year was $1,223,567; this year's purchases amounted $287,364.48 (see

    2009-06-10

    The Nez Perce Tribal Hatchery (NPTH) program has the following goals (BPA, et al., 1997): (1) Protect, mitigate, and enhance Clearwater Subbasin anadromous fish resources; (2) Develop, reintroduce, and increase natural spawning populations of salmon within the Clearwater Subbasin; (3) Provide long-term harvest opportunities for Tribal and non-Tribal anglers within Nez Perce Treaty lands within four generations (20 years) following project initiation; (4) Sustain long-term fitness and genetic integrity of targeted fish populations; (5) Keep ecological and genetic impacts to non-target populations within acceptable limits; and (6) Promote Nez Perce Tribal management of Nez Perce Tribal Hatchery Facilities and production areas within Nez Perce Treaty lands. The NPTH program was designed to rear and release 1.4 million fall and 625,000 spring Chinook salmon. Construction of the central incubation and rearing facility NPTH and spring Chinook salmon acclimation facilities were completed in 2003 and the first full term NPTH releases occurred in 2004 (Brood Year 03). Monitoring and evaluation plans (Steward, 1996; Hesse and Cramer, 2000) were established to determine whether the Nez Perce Tribal Hatchery program is achieving its stated goals. The monitoring and evaluation action plan identifies the need for annual data collection and annual reporting. In addition, recurring 5-year program reviews will evaluate emerging trends and aid in the determination of the effectiveness of the NPTH program with recommendations to improve the program's implementation. This report covers the Migratory Year (MY) 2007 period of the NPTH Monitoring & Evaluation (M&E) program. There are three NPTH spring Chinook salmon treatment streams: Lolo Creek, Newsome Creek, and Meadow Creek. In 2007, Lolo Creek received 140,284 Brood Year (BY) 2006 acclimated pre-smolts at an average weight of 34.9 grams per fish, Newsome Creek received 77,317 BY 2006 acclimated pre-smolts at an average of 24

    1987-11-01

    For the purposes of the Nuclear Waste Policy Act, the Confederated Tribes and Bands of the Yakima Indian Nation, the Confederated Tribes of the Umatilla Indian Reservation, and the Nez Perce Tribe have been accorded the status of ''Affected Indian Tribe'' and have become party to the proceedings to determine a suitable location for the nation's first commercial waste repository. Each of the Tribes has expressed concerns about the suitability of the Hanford Site in eastern Washington. These concerns, in general, address the proposed repository's effects on traditional spiritual beliefs and cultural practices, on tribal sovereignty and the Tribes' right to self-government, on the natural resources under tribal management jurisdiction, and on the health and socioeconomic characteristics of the Tribes' reservation communities. The Yakima, Umatilla, and Nez Perce have distinctive cultural traditions that may be adversely affected by activities related to the Basalt Waste Isolation Project (BWIP). Further, the Tribes enjoy a unique relationship with the federal government. Because of their distinctive cultures and governmental status, particular attention will be paid to expressed interests of the Tribes, and to ways in which these interests may be affected by the repository program. Monitoring is needed to describe current conditions among the Affected Tribes' populations, to describe BWIP site characterization activities affecting the Tribes, and to measure any changes in these conditions that may occur as a direct result of site characterization. This paper reports our first efforts at gathering historical information. It summarizes materials contained in two sources: the reports of field agents to the Commissioner of Indian Affairs (1854-1936), and the dockets of the Indian Claims Commission. 24 refs., 3 figs.

    2005-09-01

    White sturgeon in the Hells Canyon reach (HCR) of the Snake River are of cultural importance to the Nez Perce Tribe. However, subsistence and ceremonial fishing opportunities have been severely limited as a result of low numbers of white sturgeon in the HCR. Hydrosystem development in the Columbia River Basin has depressed numbers and productivity of white sturgeon in the HCR by isolating fish in impounded reaches of the basin, restricting access to optimal rearing habitats, reducing the anadromous forage base, and modifying early life-history habitats. Consequently, a proactive management plan is needed to mitigate for the loss of white sturgeon production in the HCR, and to identify and implement feasible measures that will restore and rebuild the white sturgeon population to a level that sustains viability and can support an annual harvest. This comprehensive and adaptive management plan describes the goals, objectives, strategies, actions, and expected evaluative timeframes for restoring the white sturgeon population in the HCR. The goal of this plan, which is to maintain a viable, persistent population that can support a sustainable fishery, is supported by the following objectives: (1) a natural, stable age structure comprising both juveniles and a broad spectrum of spawning age-classes; (2) stable or increasing numbers of both juveniles and adults; (3) consistent levels of average recruitment to ensure future contribution to reproductive potential; (4) stable genetic diversity comparable to current levels; (5) a minimum level of abundance of 2,500 adults to minimize extinction risk; and (6) provision of an annual sustainable harvest of 5 kg/ha. To achieve management objectives, potential mitigative actions were developed by a Biological Risk Assessment Team (BRAT). Identified strategies and actions included enhancing growth and survival rates by restoring anadromous fish runs and increasing passage opportunities for white sturgeon, reducing mortality rates

    The goal this project was to accelerate the deployment of innovative solar cell and module technologies that reduce the cost of PERC-based modules to best-in-class. New module integration technology was to be used to reduce the cost and reliance on conventional silver bus bar pastes and enhance cell efficiency. On the cell manufacturing front, the cost of PERC solar cells was to be reduced by introducing advanced metallization approaches to increase cell efficiency. These advancements will be combined with process optimization to target cell efficiencies in the range of 21 to 21.5%. This project will also explore the viability of a bifacial PERC solar cell design to enable cost savings through the use of thin silicon wafers. This project was terminated on 4/30/17 after four months of activity due financial challenges facing the recipient.

    2014-12-17

    The precise investigation of the weak interaction in free neutron decay allows to intensively test the Standard Modell and find physics beyond. In this work, the magnet system of the bright and clean proton- and electron source PERC (Proton-Electron-Radiation-Channel) was developed. It will be installed in 2016 at the research reactor FRM II. Due to improvements in systematics and statistics in comparison to its predecessor PERKEO III, observables of free neutron decay can be determined with the worldwide best precision of 10{sup -4}. In this thesis, the technical and physical properties of the magnet system will be discussed. As a major part of this work, an efficient geometry for a back-scatter detector was developed. Undetected back-scatter events for electrons would disturb the spectra in the order of 10{sup -3} for a plastic scintillator. Here, the geometry will be introduced and back-scatter events will be analyzed by simulations. For the experimental part of the present work, titanium sublimation pumps and ion getter pumps were constructed and tested. As components of the over 12 m long ultra-high vacuum system of PERC they can effectively reduce the pressure to the order of 10{sup -9} mbar over the complete length. Therefore collisions of electrons and protons with gas particles will be strongly suppressed.

    Full Text Available Crystalline silicon PERCs with dot or line openings on rear surface were studied here. By measuring the minor carrier lifetimes of the PERCs with dot and line openings, passivation effects of rear surface with dot and line openings were discussed. The performance affected by dot and line openings was analyzed in detail by testing the open-circuit voltages, short-circuit current densities, fill factors, and conversion efficiencies of the PERCs. The results show that the wider space resulted in better minor carrier lifetimes on the rear surface. And the cells with a line opening space of 0.5 mm had an average of 0.22% improvement of conversion efficiency, compared with the cells with full-area Al-BSF. On the other hand, the dot opening PERCs exhibited only a conversion efficiency of 17.4%, although there had been good rear surface reflectivity. The bad Al-Si alloy layer and large hollow densities in dot Al-contacts resulted in bad performance of the PERCs with dot openings.

  1. Juan Ramón Jiménez and Nietzsche

    Directory of Open Access Journals (Sweden)

    John P. Devlin

    1983-01-01

    Full Text Available The young Juan Ramón Jiménez shared the enthusiasm for the writings of Nietzsche prevalent among his contemporaries. More significant are the interest in and affinity with Nietzsche which persisted into the poet's maturity. Jiménez found in Nietzsche not only a man of ideas but a poet who claimed to be a potent spiritual force. Both writers held that the modern age could recover a sense of spiritual integrity through the will of the individual to live and interpret human existence as an aesthetic phenomenon. Nietzsche's views on the nature of art and the role of the artist helped to sustain Jiménez' exalted and elitist view of poetry and the poet's mission. Jiménez felt an ethical kinship with the philosopher who asserted the absolute uniqueness of the creative individual, the end of whose existence was self-realization through his art. Nietzsche's doctrine of heroic vitalism as an antidote to chronic spiritual malaise corresponds to Jiménez' revitalized vision of the poetic word proclaimed in the Diario and elaborated in subsequent verse and prose writings.

    2012-06-01

    Full Text Available O risco é uma entidade omnipresente nos locais de trabalho. Esta é uma situação que todos os trabalhadores têm de enfrentar no seu quotidiano laboral, embora cada atividade, profissão ou indivíduo detenha um grau de risco específico, normalmente distinto nas diversas ocupações laborais e que está associado às suas tarefas concretas. É através da enorme multiplicidade de riscos no trabalho, variável em cada universo laboral, que chegamos aos acidentes de trabalho. Cada acidente só ocorre porque a montante existe um qualquer conjunto de riscos laborais que se transformou em acidente. Os riscos laborais são assim a causa única dos acidentes de trabalho. É neste contexto que nos parece pertinente considerar a forma como os próprios trabalhadores percebem os riscos aos quais se encontram expostos nos seus locais de trabalho, visto que se um trabalhador não consegue identificar (ou identifica de forma inadequada os seus riscos laborais, aparentemente, estará mais vulnerável a sofrer um acidente de trabalho. O estudo sobre as perceções de riscos é um campo de observação científica relativamente recente; talvez por esse motivo ainda não se tenha chegado a resultados totalmente conclusivos – embora já saibamos algumas tendências - sobre como são geradas as perceções de riscos dos trabalhadores, bem como qual a influência que efetivamente detêm na ocorrência dos acidentes de trabalho. Ao longo deste artigo iremos abordar esta temática.

    The aim of this study was to report a single surgeon series of consecutive patients with moderate hallux valgus managed with a percutaneous extra-articular reverse-L chevron (PERC) osteotomy. A total of 38 patients underwent 45 procedures. There were 35 women and three men. The mean age of the patients was 48 years (17 to 69). An additional percutaneous Akin osteotomy was performed in 37 feet and percutaneous lateral capsular release was performed in 22 feet. Clinical and radiological assessments included the type of forefoot, range of movement, the American Orthopedic Foot and Ankle (AOFAS) score, a subjective rating and radiological parameters. The mean follow-up was 59.1 months (45.9 to 75.2). No patients were lost to follow-up. The mean AOFAS score increased from 62.5 (30 to 80) pre-operatively to 97.1 (75 to 100) post-operatively. A total of 37 patients (97%) were satisfied. At the last follow up there was a statistically significant decrease in the hallux valgus angle, the intermetatarsal angle and the proximal articular set angle. The range of movement of the first metatarsophalangeal joint improved significantly.. There was more improvement in the range of movement in patients who had fixation of the osteotomy of the proximal phalanx. Preliminary results of this percutaneous approach are promising. This technique is reliable and reproducible. Its main asset is that it maintains an excellent range of movement. The PERC osteotomy procedure is an effective approach for surgical management of moderate hallux valgus which combines the benefits of percutaneous surgery with the versatility of the chevron osteotomy whilst maintaining excellent first MTPJ range of motion. ©2016 The British Editorial Society of Bone & Joint Surgery.

  9. Low Cost Local Contact Opening by Using Polystyrene Spheres Spin-Coating Method for PERC Solar Cells

    Directory of Open Access Journals (Sweden)

    Chia-Hsun Hsu

    2016-07-01

    Full Text Available The passivated emitter and rear cell (PERC concept is one of the most promising technologies for increasing crystalline silicon solar cell efficiency. Instead of using the traditional laser ablation process, this paper demonstrates spin-coated polystyrene spheres (PS to create local openings on the rear side of PERCs. Effects of PS concentration and post-annealing temperature on PERC performance are investigated. The experimental results show that the PS are randomly distributed on wafers and no PS are joined together at a spin rate of 2000 rpm. The PS can be removed at a temperature of 350 °C, leaving holes on the passivation layers without damaging the wafer surfaces. As compared to the laser opening technique with the same contact fraction, the PS opening technique can yield a higher minority effective lifetime, a higher implied open-circuit voltage, and a slightly higher short-circuit current. Although the fill factor of the PS opening technique is lower owing to non-optimized distribution of the openings, the conversion efficiency of the devices is comparable to that of devices prepared via the laser opening process.

This implies that the low-temperature equilibrium shapes of many metal crystals should be heavily faceted. The predicted ins...... instability of vicinal metal surfaces is at variance with the almost generally observed stability of these surfaces. We argue that the unstable orientations undergo a defaceting transition at relatively low temperatures, driven by the high vibrational entropy of steps....

    The ability of the pulmonary embolism rule-out criteria (PERC) to exclude pulmonary embolism without further testing remains debated outside the USA, especially in the population with suspected pulmonary embolism who have a high prevalence of the condition. Our main objective was to prospectively assess the predictive value of negative PERC to rule out pulmonary embolism among European patients with low implicit clinical probability. We did a multicentre, prospective, observational study in 12 emergency departments in France and Belgium. We included consecutive patients aged 18 years or older with suspected pulmonary embolism. Patients were excluded if they had already been hospitalised for more than 2 days, had curative anticoagulant therapy in progress for more than 48 h, or had a diagnosis of thromboembolic disease documented before admission to emergency department. Physicians completed a standardised case report form comprising implicit clinical probability assessment (low, moderate, or high) and a list of risk factors including criteria of the PERC rule. They were asked to follow international recommendations for diagnostic strategy, masked to PERC assessment. The primary endpoint was the proportion of patients with low implicit clinical probability and negative PERC who had venous thromboembolic events, diagnosed during initial diagnostic work-up or during 3-month follow-up, as externally adjudicated by an independent committee masked to the PERC and clinical probability assessment. The upper limit of the 95% CI around the 3-month thromboembolic risk was set at 3%. We did all analyses by intention to treat, including all patients with complete follow-up. This trial is registered with ClinicalTrials.gov, number NCT02360540. Between May 1, 2015, and April 30, 2016, 1773 consecutive patients with suspected pulmonary embolism were prospectively assessed for inclusion, of whom 1757 were included. 1052 (60%) patients were classed as having low clinical probability

    Full Text Available The article entitled Francisco Ibarra Martínez: reformer of Cuban Pedagogy, is first of all a well deserved homage to one of the most important pedagogues of the republican period. His thought and his work are approached, from his initial stage of academic formation to his contributions to the educational cuban thought. Stands out his social dimension of his pedagogic work, his integration to the civic life of the city, his reforming vision of the practice of sports and study of the history of his country. Likewise, we refer to his contributions to the historiography as a science, the journalism and his concern for the social and political destination of the country. For this reason this work has among its contributions the treatment to the local history from the specific fild of pedagogy and education, modestly contributing to the rescue of historic memory.

  8. Juan Ramón Jiménez: Of Naked Poetry and The Master Poet (1916-1936

    Directory of Open Access Journals (Sweden)

    1983-01-01

    Full Text Available The phrase naked poetry was coined by Juan Ramón Jiménez in 1916 and represents a style which influenced an outstanding generation of poets in twentieth-century Spain, among them Jorge Guillén, Pedro Salinas, Rafael Alberti, Luis Cernuda, Vicente Aleixandre and many others. This symbol is rooted in a sublimated concept of the essential naked woman, his wife, loved and possessed by the poet. At the same time it represents an essential poetry, devoid of all external adornment. It was used by Jiménez immediately after his marriage in a short poem which traces a parallel between the evolution of his poetic style and the sentimental episodes of his love life. It is related to disrobing ( desnudar , a verb which originated in Spain with a mystical connotation meaning "to give up," "to deprive oneself," "to renounce." In the poetic career of Jiménez it is the point of departure for an artistic asceticism which leads to the neomystic union with a divinity described in Animal de fondo (Animal of the Depth , his last major work, of 1949. In the years of the preeminence of Jiménez (1916-1936, Spanish and foreign critics had great trouble explaining his new style. They called it stark, stripped, cryptic; they said that it created, aesthetically, a sense of incompleteness; that it turned sensations into concepts; that it expressed all which in nature is incapable of concrete realization. A review of this early criticism helps to convey the character of Jiménez' naked poetry in the years when he became the master poet of Spain.

    The bioaccumulation mechanism expresses an increment of mercury concentration along the lifetime of each individual. It is generally investigated along the age or size range of organisms from a same population. Water chemistry and trophic position are important factors that may influence the emergence of bioaccumulation patterns. In order to detect the influence of these parameters on fish mercury bioaccumulation patterns, we explored the relations between mercury concentration, size and isotopic trophic position of fish populations of six species (three non piscivorous and three piscivorous) in three rivers of the Iténez basin (Bolivia) with different sediment load in water and anthropogenic impact. Fishes of the Iténez basin showed fairly lower mercury contamination in relation to the regional context. They presented lower total mercury concentrations in unperturbed clear water river (average of 0.051 μg g(-1) for non piscivores; 0.088 μg g(-1) for piscivores), intermediate values (average of 0.05 and 0.104 μg g(-1)) in unperturbed white water river, whereas the highest values (average of 0.062 and 0.194 μg g(-1)) were found in the perturbed clear water river. Piscivore and invertivore species showed significant positive bioaccumulation patterns in the perturbed river and in the unperturbed white water river. No positive pattern was detected in the unperturbed clear water river. Positive patterns could not be attributed to differences in trophic condition and mean fish mercury concentration between populations. Bioaccumulation seems not to be the main factor to explain increased mercury concentrations in fish from the perturbed river. Copyright © 2012 Elsevier Inc. All rights reserved.

    Introduction Computerized decision support decreases the number of computed tomography pulmonary angiograms (CTPA) for pulmonary embolism (PE) ordered in emergency departments, but it is not always well accepted by emergency physicians. We studied a department-endorsed, evidence-based clinical protocol that included the PE rule-out criteria (PERC) rule, multi-modal education using principles of knowledge translation (KT), and clinical decision support embedded in our order entry system, to decrease the number of unnecessary CTPA ordered. Methods We performed a historically controlled observational before-after study for one year pre- and post-implementation of a departmentally-endorsed protocol. We included patients > 18 in whom providers suspected PE and who did not have a contraindication to CTPA. Providers entered clinical information into a diagnostic pathway via computerized order entry. Prior to protocol implementation, we provided education to ordering providers. The primary outcome measure was the number of CTPA ordered per 1,000 visits one year before vs. after implementation. Results CTPA declined from 1,033 scans for 98,028 annual visits (10.53 per 1,000 patient visits (95% CI [9.9–11.2]) to 892 scans for 101,172 annual visits (8.81 per 1,000 patient visits (95% CI [8.3–9.4]) p<0.001. The absolute reduction in PACT ordered was 1.72 per 1,000 visits (a 16% reduction). Patient characteristics were similar for both periods. Conclusion Knowledge translation clinical decision support using the PERC rule significantly reduced the number of CTPA ordered. PMID:29085542

    La lepra es una enfermedad que se caracteriza por la insidia de su presencia, su lenta evolución y la progresiva incapacidad que en sus víctimas causa.

    Esto y el temor que ha infundido desde tiempos bíblicos, han hecho que ante ella se haya mantenido una actitud ambivalente de negación hasta donde es posible y de rechazo irracional a quien la padece, por temor al contagio.

    Ejemplo de ello es el aura de sagrado misterio que envuelve la leyenda de los padecimientos del Adelantado don Gonzalo Jiménez de Quesada (1509-1579, conquistador del Nuevo Reino de Granada y fundador de Santafé de Bogotá en el año de 1538, muerto a la edad, avanzada para la época, de setenta años.

    No se puede afirmar, en forma definitiva, que el conquistador fuera leproso. Se acepta, acogiendo el argumento de autoridad que tiene el primer historiador médico entre nosotros, don Pedro María Ibáñez, quien escribió en 1884, en las Memorias para la Historia de la Medicina en Santa Fe, que en “1579 falleció en la ciudad de Mariquita, y de mal de lepra o elefancía de los

    Eduardo Martínez Alonso was of Spanish and Uruguyan extraction and was born in Vigo in Galicia in 1903. Due to his father's occupation, he was educated in the UK and qualified from the University of Liverpool. He returned to Madrid to practise and during the Civil War he found himself in the Republican zone where his connections with the Royal Family brought him under suspicion. Threatened with execution, he escaped to serve as a surgeon in the Nationalist Army. Being bilingual, he was medical adviser to the British Embassy during World War II; because of his allegiance to this country and acting from humanitarian motives, he became a ringleader in a plot to smuggle fugitives from Nazi-occupied Europe across a pro-Axis Spain to safety. When the Gestapo was closing in on him, he was smuggled to the UK via Portugal. He underwent training as a potential undercover agent should Franco take Spain into the war but, when hostilities ceased, he returned to Madrid and became a leading thoracic surgeon.

Participaram do estudo 217 acadêmicos, com média de 20.6 anos de idade (DP = 0.6, sendo 54.8% do sexo masculino. Coletaram-se informações sobre perceção da imagem corporal por meio da escala de silhuetas de Stunkard et al. (1983. O nível de escolaridade dos pais e dados sociodemográficos foram coletados por questionário autoadministrado. Empregaram-se a estatística descritiva e a regressão logística multinomial, adotando-se nível de significância de 5%. Em relação à perceção da imagem corporal, 41% dos alunos estavam insatisfeitos por magreza e 28.1% por excesso de peso. As chances de insatisfação por excesso de peso foram de sete a oito vezes maiores nos acadêmicos com escolaridade materna superiores a quatro anos de escolaridade, independentemente de sexo, idade, situação conjugal, nível econômico e curso.

Este carácter si bien puede albergar dudas, no debe transformase en un fatalismo inmovilizador, que permite la actualización constante del libre mercado como institución hegemónica. Antes que una utopía a denunciar desde una visión “realista”, se trata de construir una economía que combine mecanismos de mercado regulados socio-políticamente y relaciones de reciprocidad y redistribución. El texto explora, en pos de la argumentación, algunos de los elementos que conforman la economía social y solidaria.This article represents the author's response to critical commentary made in this section in the last edition by Luciano Martinez. The author maintains that the social and solidarity economy is a sphere under construction, in which several strands can be found. All of these approaches aim to move towards a different type of economy. This character as a developing realm can prompt doubts; this, however, should not lead to a paralyzing fatalism which allows the constant updating of the free market as a hegemonic institution. Far from a utopia to be denounced from a “realistic” viewpoint of economy, its concerns the construction of an economy that combines socio-politically regulated market mechanisms as well as relations of reciprocity and redistribution. The text also explores some of the elements that make up the solidarity and social economy.

  9. Self-assembled nanostructures on vicinal surfaces

    Petrovykh, Dmitri Yourievich

    2000-10-01

    One of the first methods for visualizing crystal planes and atomic steps has been step decoration with gold on alkali-halide surfaces. An impressive body of work has been conducted since then on the role of steps in controlling surface diffusion and adsorption rates, catalytic and chemical activity, and other physical and chemical surface properties. Due to these special characteristics, vicinal surfaces offer an approach for creating self-assembled structures with one or more dimensions on nanometer scale. The storage and communications industries have been revolutionized by applications of two-dimensional electron gas confined in thin films, so an interest in one and zero-dimensional systems is not surprising. This work demonstrates how macroscopic amounts of low-dimensional structures can be produced by self-assembly using stepped surfaces as nanometer-scale templates. High-quality templates of step arrays can be prepared on vicinal Si(111) surfaces. Sub-monolayer CaF2/Si(111) heteroepitaxial growth is examined in a series of experiments. A new growth mode is observed in addition to the ones typical in three dimensions. With increasing coverage, the growth front changes from rough to smooth geometry, driven by the elastic interactions between the multiple growth fronts and the surface steps. The mechanism is thus unique to the two-dimensional growth on stepped surfaces. The possible arrangements of the CaF2 self-assembled nanostructures are arrays of stripes or islands, both interesting as potential masks for silicon nanolithography. Anisotropic surface reconstructions, such as Ca and Au induced 3 x 1 and 5 x 2 on Si(111), are effectively self-assembled one-dimensional atomic chains. Reconstructions are single-domain on vicinal surfaces and with odd electron count a metallic one-dimensional state is expected in both the above examples. However in angular-resolved photoemission both appear as semiconductors, and Au-Si(111)5 x 2 exhibits a continuous one

    The aim of this study was to evaluate whether clinical improvement is noticeable after a minimally invasive procedure such as that used with the Aperius PercLID System in patients with degenerative lumbar spinal stenosis (DLSS) and neurogenic intermittent claudication (NIC). The patients were treated with the aforementioned system at 3 different centers. The initial requirement to be included in the study was a minimum follow-up of 12 months. The authors studied 40 cases of DLSS in patients with NIC (age 72.7 +/- 8.08 years). Symptom severity, physical function, quality of life, and self-rated pain were assessed preoperatively and at the 12-month follow-up using the Zurich Claudication Questionnaire (ZCQ) and a visual analog scale. The procedure was conducted under spinal (35 patients) or local (5 patients) anesthesia, using biplanar fluoroscopy for visualization. Single-level treatment was performed in 28 patients and 2-level treatment was performed in 12 patients. Based on time recordings in 24 cases, the mean procedural time was 19.9 +/- 5.0 minutes. The mean pain visual analog scale score improved significantly from 8.1 +/- 2.19 at baseline to 3.44 +/- 2.89 at the 1-year follow-up. The ZCQ score for patient satisfaction showed 90% of the patients being satisfied with the procedure. The mean rates of improvement in ZCQ score for symptom severity and physical function at 1 year were 38.7 +/- 33.3% and 33.8 +/- 29.7%, respectively, and both proved to be statistically significant. Most improvement was seen in mobility, pain/discomfort, and ability for self-care. In this preliminary study, the Aperius system provided clinically significant improvement after 1 year of follow-up in patients older than 65 years with DLSS and NIC.

    The past several years have seen a rapidly growing interest in the use of advanced quantitative methodologies and formalisms adapted from the natural sciences to study a broad range of social phenomena. The research field of computational social science [1,2], for example, uses digital artifacts of human online activity to cast a new light on social dynamics. Similarly, the studies reviewed by D'Orsogna and Perc showcase a diverse set of advanced quantitative techniques to study the dynamics of crime. Methods used range from partial differential equations and self-exciting point processes to agent-based models, evolutionary game theory and network science [3].

    The Valencian engraver Crisóstomo Martínez (ca. 1638-1694) arrived in Paris in July 1687, commissioned to create an anatomical atlas. Impressed by Govard Bidloo's Anatomia humani corporis (1685), Martínez decided to make a comparable work on osteology. His unpublished atlas of anatomy was exceptional in its choice of topic, its quality, and its overall visual approach. Martínez's work revolves around the dissolving effects of microscopic study on the traditional understanding of the connections between parts and whole. Underlying his investigation into the most effective composition of an anatomical atlas was the idea of the self-organizing and complex nature of the body as itself a composition, an idea rooted in the way observation and judgment, the seen and the unseen, and notions about collections and communities were connected in the vanitas culture. This essay explores the links between Martínez's work and the cultures of a time in which observation and interpretation of the processes of death, decay, and fragmentation played a primary role in defining a common human nature around which notions of destiny could be articulated.

    One generally expects the properties of a vicinal surface to be independent of the existence of steps as soon as these steps overlap, i.e. when their mutual distance is smaller than their width. By using the roughening theory by Nozières and Gallet [1], we show that, at least for surfaces weakly coupled to the lattice, this overlap occurs for distances significantly larger than the commonly defined width. Our prediction is supported by an analysis of the various measurements of the angular variation of the surface stiffness of helium crystals, which were performed by Wolf et al. [2], Andreeva et al. [3] and Babkin et al. [4]. As a consequence, the interaction between crystal steps should be studied on vicinal surfaces with a much smaller tilt angle than previously thought. This article is also an opportunity to return to the relation between the step width and the correlation length on smooth surfaces, as well as to the treatment of the various finite size effects which occur in the problem of roughening. We finally reconsider how the weak coupling hypothesis applies to the case of helium crystals. On s'attend généralement à ce que les propriétés d'une surface vicinale ne soient plus contrôlées par l'existence des marches lorsque celles-ci se recouvrent, donc lorsque leur distance mutuelle devient inférieure à leur largeur. En reprenant la théorie de la transition rugueuse élaborée par Nozières et Gallet [1], nous montrons que, pour des surfaces faiblement couplées au réseau cristallin, ce recouvrement doit se produire pour des distances nettement plus grandes que la largeur (telle qu'elle est habituellement définie). Notre prédiction est confirmée par l'analyse des différentes mesures de la variation angulaire de la rigidité de surface des cristaux d'hélium réalisées par Wolf et al. [2], Andreeva et al. [3] and Babkin et al. [4]. Il s'ensuit que l'étude de l'interaction entre marches cristallines doit être effectuée sur des surfaces

    The purpose of this intern`s project was to: education the Nez Perce people of the Hanford situation; begin researching into past and present health effects from the Hanford site; and inform and educate the Nez Perce people of the Hanford site and past exposures. The specific objectives were to begin researching the history of Nez Perce people and Hanford; create an understanding for the importance of this research; define the radiation and risks and how they occur; inform the Nez Perce people of the issue; and write the paper so it is easy to understand. This intern report contains a copy of the final paper written for the Nez Perce people. Because the dose reconstruction for Hanford is not complete, the health effects section is informative, but not definitive.

    2006-12-01

    Full Text Available In 1830, the philologist Pedro Martínez López was forced to go into exile in France for political reasons. In 1832, he published Representación a Fernando VII, rey de España, a lampoon in which he made a whole string of accusations against the tyrant. At the end of the following year, he published España en 1833, al expirar Fernando VII, another lampoon in which he blamed the king's despotic reign for the country's disastrous situation and asserted that such abuses and injustices could only be remedied by re-establishing the Constitution of Cádiz of 1812. In 1834, he ceased to rail against his political enemies, changed strategy, and using his considerable imagination, wrote a kind of fable entitled Una noche en el infierno, vista entre sueños. With a mixture of humour and acid wit, it told of how all the devils in the Kingdom of Darkness, embracing the «sacred» cause of liberalism, vented their anger on the deceased Ferdinand and his followers, who were still in power. It would appear that the work was a success, since it was republished in 1836. In 1835, disillusioned with the tepid and conservative liberal regime of the Estatuto Real, Martínez López wrote another story, Las Brujas en Zugarramurdi, in which different satanic creatures, this time sorceresses, take it upon themselves to defeat moderantismo and establish a progressive regime. After this, he ceased to publish lampoons and political parables and devoted himself to producing learned works, bringing out various dictionaries and grammars which were republished several times. | En 1830, el filólogo Pedro Martínez López tuvo que exiliarse a Francia por motivos políticos.

    Directory of Open Access Journals (Sweden)

    Jaume Garau

    2015-11-01

    Full Text Available Throughout his works, Bartolomé Jiménez Patón mentions Portugal and some of its writers on a number of occasions. In the books that have been recovered of his Comentarios de erudición (1621, he cites authors such as Fernando López de Castañeda or Joao de Barros, who are associated with the popular vogue of the period for portentous works, of which the Spanish Humanist was so fond of. A large number of his commentaries concerning Portugal center on justifying dynastic unity, based on his interpretation of the history of Gregorio López Madera, who he admired so much, which has as its background the image of Hispania. To a certain extent, the new government of Olivares would try to carry out this policy. Of no less interest is his description of the city of Lisbon in which he presents the idea of ‘exemplariness’, a notion he has in common with other descriptions by Mateo Alemán, Cervantes or Tirso, although in Patón’s, such exemplariness appears in contrast with the picturesque depiction of the rogues of the Rua Nova.

    Arizona. Outcrop analogs are found in the stratigraphically equivalent Navajo Sandstone of southern Utah which displays large-scale dunal cross-strata with excellent reservoir properties and interdunal features such as oases, wadi, and playa lithofacies with poor reservoir properties. Hydrocarbons in the Paradox Formation are stratigraphically trapped in carbonate buildups (or phylloid-algal mounds). Similar carbonate buildups are exposed in the Paradox along the San Juan River of southeastern Utah. Reservoir-quality porosity may develop in the types of facies associated with buildups such as troughs, detrital wedges, and fans, identified from these outcrops. When combined with subsurface geological and production data, these outcrop analogs can improve (1) development drilling and production strategies such as horizontal drilling, (2) reservoir-simulation models, (3) reserve calculations, and (4) design and implementation of secondary/tertiary oil recovery programs and other best practices used in the oil fields of Utah and vicinity. During this quarter, technology transfer activities consisted of exhibiting the project plans, objectives, and products at a booth at the 2003 annual convention of the American Association of Petroleum Geologists.

    fractured and sealed by overlying argillaceous and non-fractured units. The best outcrop analogs for Twin Creek reservoirs are found at Devils Slide and near the town of Peoa, Utah, where fractures in dense, homogeneous non-porous limestone beds are in contact with the basal siltstone units (containing sealed fractures) of the overlying units. The shallow marine, Mississippian Leadville Limestone is a major oil and gas reservoir in the Paradox Basin of Utah and Colorado. Hydrocarbons are produced from basement-involved, northwest-trending structural traps with closure on both anticlines and faults. Excellent outcrops of Leadville-equivalent rocks are found along the south flank of the Uinta Mountains, Utah. For example, like the Leadville, the Mississippian Madison Limestone contains zones of solution breccia, fractures, and facies variations. When combined with subsurface geological and production data, these outcrop analogs can improve (1) development drilling and production strategies such as horizontal drilling, (2) reservoir-simulation models, (3) reserve calculations, and (4) design and implementation of secondary/tertiary oil recovery programs and other best practices used in the oil fields of Utah and vicinity. In the southern Green River Formation play of the Uinta Basin, optimal drilling, development, and production practices consist of: (1) owning drilling rigs and frac holding tanks; (2) perforating sandstone beds with more than 8 percent neutron porosity and stimulate with separate fracture treatments; (3) placing completed wells on primary production using artificial lift; (4) converting wells relatively soon to secondary waterflooding maintaining reservoir pressure above the bubble point to maximize oil recovery; (5) developing waterflood units using an alternating injector--producer pattern on 40-acre (16-ha) spacing; and (6) recompleting producing wells by perforating all beds that are productive in the waterflood unit.

    As poliovirus eradication draws closer, alternative Inactivated Poliovirus Vaccines (IPV) are needed to overcome the risks associated with continued use of the Oral Poliovirus Vaccine and of neurovirulent strains used during manufacture of conventional (c) IPV. We have previously demonstrated the susceptibility of the PER.C6(®) cell line to cIPV strains; here we investigated the suspension cell culture platform for growth of attenuated poliovirus strains. We examined attenuated Sabin strain productivity on the PER.C6(®) cell platform compared to the conventional Vero cell platform. The suitability of the suspension cell platform for propagation of rationally-attenuated poliovirus strains (stabilized Sabin type 3 S19 derivatives and genetically attenuated and stabilized MonoCre(X) strains), was also assessed. Yields were quantified by infectious titer determination and D-antigen ELISA using either serotype-specific polyclonal rabbit sera for Sabin strains or monoclonal cIPV-strain-specific antibodies for cIPV, S19 and MonoCre(X) strains. PER.C6(®) cells supported the replication of Sabin strains to yields of infectious titers that were in the range of cIPV strains at 32.5°C. Sabin strains achieved 30-fold higher yields (pIPV vaccines needed for achieving and maintaining poliovirus eradication. Copyright © 2015 Elsevier Ltd. All rights reserved.

    This study aimed to characterize environmental hazards of pesticides from pineapple production in riparian communities along the Jiménez River watershed. To achieve our objectives riparian ecological quality indices on riparian habitat and macroinvertebrate assemblages were combined with toxicity assays, fish biomarkers, physico-chemical water analysis and pesticide environmental hazards. During two consecutive years and two periods (July and October), three reference and four impacted sites were monitored. The ecological quality of benthic macroinvertebrates and of riparian habitats deteriorated from the reference sites downstream to the polluted reaches along the Jiménez River area affected by pineapple plantations. The toxicity of water to Daphnia magna also increased towards downstream reaches. Biomarkers of fish of the species Poecilia gillii and Bryconamericus scleroparius transplanted across the studied sites evidenced a clear anticholinergic effect towards downstream sites as well as increased levels of lipid peroxidation. Different pesticide residues were frequently detected in water samples collected across the Jiménez River watershed with herbicides (ametryn, bromacil, diuron), organophosphorus insecticides (diazinon and ethoprophos) and triazole fungicides being the greatest reaching levels above 1 μg L(-1) in downstream sites. Principal component and environmental hazard analysis of physico-chemical and biological responses established clear relationships among habitat deterioration and the ecological quality of macroinvertebrate communities, high levels of herbicides and poor plant growth, high levels of organophosphorus insecticides in water and anticholinesterase effects on fish, D. magna mortality and deterioration of macroinvertebrate communities. Fungicide and herbicide residue levels were also related with high levels of lipid peroxidation and high activities of glutathione S transferase in fish liver, respectively. These results indicated

    On the centenary of the foundation of the Paediatrics Society of Madrid, a tribute is presented to rural medical practice of that time, although there are few documents on the history of rural medicine. The main objective is to describe the context of the rural medical practice in the late 19th and beginning 20th century, while presenting a historical biographical review of Manuel Martínez Saldise, who was medical specialist from Cazalegas (Toledo). He was appointed an Honorary Member by the Paediatrics Society of Madrid in 1927. A search was carried out in repositories of digitized media, web portals of history of medicine, PubMed, IME files of local councils and medical colleges. The family archives were reviewed with the collaboration of his descendants. The hiring of rural doctors was carried out by the municipalities, and the salary largely depended on private practice as well as "retainers". Specialist physicians took part in epidemics, legal medicine, and in hygiene measures. They also had disputes with mayors, chiefs, with colleagues and with protectionism. A summary of the biography and occupational activity of Manuel Martínez Saldise is presented. Rural doctors were subjected to the society of their time, with the issues that arose, denouncing the shortcomings of the local administrations, dedicated efforts to their family and the most disadvantaged.

Slightly increased concentrations of I-131 in Richland drinking water were observed during the last two weeks of the month. Radioiodine detected in several milk samples (maximum 25 pCi/l) was attributed to fallout from an announced nuclear weapons test of December 24, 1967. Increased beta activities on air filters were also attributed to fallout.

    Full Text Available A LA COSTA DE LUIS A. MARTINEZ : LA DEFENSE D’UN PROJET LIBERAL POUR L’ÉQUATEUR ? A la Costa est souvent analysé comme une peinture de moeurs, témoignage de la réalité sociale et politique de l´Équateur de la fin du XIX et du début du XX. En effet, ce roman prétend décrire le conflit traditionnel qui oppose socialement, économiquement et politiquement les Andes et la Côte. Mais il se présente aussi et surtout comme la défense d´un projet libéral pour l´Équateur et développe une démonstration idéologique systématique. En outre, il propose une lecture du sens de la vie et une réflexion sur le devenir de l´homme dont la portée dépasse largement l´argumentation idéologique. Ce sont sans aucun doute ces nuances, introduites tout au long de la narration, qui permettent à l´oeuvre d´échapper à son statut exemplaire, simple témoignage d´une époque, pour proposer une vision personnelle et créative. Muchos han visto en A la Costa una novela de tendencia costumbrista, testimonio de la realidad social y política del Ecuador a finales del siglo XIX y comienzos del XX. En efecto, la novela pretende describir el conflicto tradicional social, económico, político entre Sierra y Costa. Pero es también, y ante todo, la defensa de un proyecto liberal para Ecuador, desarrollando una sistemática demostración ideológica. Además, propone una lectura del sentido de la vida y una reflexión sobre el porvenir del hombre cuyo alcance va más allá de la defensa de un proyecto ideológico. Sin duda son estos matices, introducidos a lo largo de la narración, los que permiten que la obra escape del estatuto de novela ejemplar y testimonial para proponer una visión autónoma y creativa.

    Full Text Available The biography of Joaquín Ruiz-Giménez is a virtual paradigm of two historical phenomena which distinguished the last two decades of the Franco regime and, to a large extent, paved the way for the future democracy: on the one hand, the rift between Catholic and Falangist intellectuals and the regime which they had enthusiastically helped to establish after the civil war; and on the other, the secularization of its political thinking and practice. Ruíz-Giménez, ambassador and minister under Franco, was an exception among the Catholic laity that collaborated with the dictatorship, in that he held high government positions and, despite all the reservations concerning his personal development, for many of his peers as well as many aspiring figures of the coming generations, he symbolized the definitive renunciation of all legitimacy of power based on victory in battle or on Catholic natural law, and the definitive adoption of the language of human rights and democracy. | La biografía de Joaquín Ruiz-Giménez representa casi de manera paradigmática dos fenómenos históricos que caracterizaron las dos últimas décadas del franquismo y sentaron, en buena medida las bases de la futura democracia: por un lado, el alejamiento de los intelectuales católicos y falangistas respecto al régimen que habían contribuido a levantar con entusiasmo tras la guerra civil; por otro, la secularización de su pensamiento y práctica política. Ruiz-Giménez, embajador y ministro de Franco, fue una excepción entre los seglares católicos que colaboraron con la dictadura desempeñando altas responsabilidades de gobierno y, pese a todas las cautelas de su evolución personal, simbolizó para bastantes compañeros de su generación, así como para muchos jóvenes alumnos de las nuevas generaciones, la renuncia definitiva a toda legitimación del poder basada en la victoria de las armas o en el iusnaturalismo católico y la adopción irreversible del lenguaje de

  8. Towards a Poetry of Silence: Stéphane Mallarmé and Juan Ramón Jiménez

    Directory of Open Access Journals (Sweden)

    Mervyn Coke-Enguídanos

    1983-01-01

    Full Text Available In an era of apparent dissolution, "la Obra" of Juan Ramón Jiménez, like "l'Oeuvre" of Stéphane Mallarmé, has for its goal the attainment of timelessness. In both poets, the concept of absolute Time—the timelessness of eternal Time—is yoked with the ideal of silence. But this is no ordinary silence, and certainly not the kind that results from inadequacy of expression. It is the silence of perfection, the expression of the ineffable: pure Poetry. Since the poetic language is the silent language of thought, both Mallarmé and Juan Ramón seek to convey the pure idea. In so doing, both must stringently eliminate whatever is not essential in their poetry. The astonishing paradox, central to Mallarmé and Juan Ramón alike, is the urge to create an "unwritten" poetry.

    Directory of Open Access Journals (Sweden)

    Andrew P. Debicki

    1983-01-01

    Full Text Available Both Juan Ramón Jiménez and Salinas reveal in their poems a striving to capture the essences of things, continuing in this quest a tradition coming to them from symbolist poetry. By examining several poems written by them, however, we discover a basic difference in their way of embodying this striving. Juan Ramón, concerned with the perfection of form, remains within a logocentric tradition in which the poem attempts to embody its meanings objectively; Salinas, on the other hand, writes poems the meanings of which evolve with successive readings and reflect the theme of reality's fleetingness. A close analysis of the texts exemplifies this difference and also suggests that in spite of it the poems of both authors remain subject to possible "deconstructions" on the part of the reader.

  15. What can we learn from the deadly flash floods? Post Event Review Capability (PERC) analysis of the Bavaria and Baden-Wurttemberg flood events in Summer 2016

    Science.gov (United States)

    Szoenyi, Michael

    2017-04-01

    In May/June 2016, stationary low pressure systems brought intense rainfall with record-braking intensities of well above 100 mm rain in few hours locally in the southern states of Baden-Wurttemberg and Bavaria, Germany. In steep terrains, small channels and creeks became devastating torrents impacting, among others, the villages of Simbach/Inn, Schwäbisch-Gmünd and Braunsbach. Just few days prior, France had also seen devastating rainfall and flooding. Damage in Germany alone is estimated at 2.8 M USD, of which less than 50% are insured. The loss of life was significant, with 18 fatalities reported across the events. This new forensic event analysis as part of Zurich's Post Event Review Capability (PERC) investigates the flash flood events following these record rainfalls in Southern Germany and tries to answer the following questions holistically, across the five capitals (5C) and the full disaster risk management (DRM) cycle, which are key to understanding how to become more resilient to such flood events: - Why have these intense rainfall events led to such devastating consequences? The EU Floods directive and its implementation in the various member states, as well as the 2002 and 2013 Germany floods, have focused on larger rivers and the main asset concentration. The pathway and mechanism of the 2016 floods are very different and need to be better understood. Flash floods and surface flooding may need to become the new focus and be much better communicated to people at risk, as the awareness for such perils has been identified as low. - How can the prevalence for such flash floods be better identified and mapped? Research indicated that affected people and decision makers alike attribute the occurrence of such flash floods as arbitrary, but we argue that hotspots can and must be identified based on an overlay of rainfall intensity maps, topography leading to flash flood processes, and vulnerable assets. In Germany, there are currently no comprehensive hazard

    2012-06-01

    Full Text Available In the manuscript of El virtuoso discreto [The Virtuous Discreet Man], the humanist and grammarian Bartolomé Jiménez Patón reveals himself to be a zealous defender of orthodoxy. This work, formulated as a complement to his pedagogical duties as Professor of Eloquence, manifests its author’s purpose of participating in the religious controversy of his times, particularly in those fundamental aspects that distance Tridentine Catholicism from Lutheranism. Thus, part of the work is dedicated to a reflection on the concept of the Church, free will and theological justification, the doctrine of which was central to the development of the Council of Trent and the seven sacraments. No less important in this manuscript is Patón’s impassioned condemnation of illuministic heresy, the only genuinely Spanish doctrine of this sort in the Modern Age, whose members were also known in Spanish as alumbrados or agapetas.En el ms. de El virtuoso discreto, el humanista y gramático Bartolomé Jiménez Patón se muestra como un receloso defensor de la ortodoxia. La obra, concebida como un complemento a su enseñanza en su cátedra de Elocuencia, evidencia el propósito de su autor de participar en la controversia religiosa de su tiempo, particularmente en aquellos aspectos fundamentales que distancian al catolicismo tridentino del luteranismo. Así, parte de la obra se ocupa en reflexionar sobre el concepto de Iglesia, el libre albedrío y la justificación, cuya doctrina fue central en el desarrollo del concilio de Trento, y los siete sacramentos. No menor importancia presenta su apasionada condena de la herejía iluminista, la única genuinamente española en la Edad Moderna, cuyos miembros fueron también conocidos como alumbrados o agapetas.

    We analyze the effect of scheme transformations in the vicinity of an exact or approximate infrared fixed point in an asymptotically free gauge theory with fermions. We show that there is far less freedom in carrying out such scheme transformations in this case than at an ultraviolet fixed point....... We construct a transformation from the $\\bar{MS}$ scheme to a scheme with a vanishing three-loop term in the $\\beta$ function and use this to assess the scheme dependence of an infrared fixed point in SU($N$) theories with fermions. Implications for the anomalous dimension of the fermion bilinear...

    Full Text Available Landfill sites are the easiest, the cheapest and the most common way of waste management and disposal. In the face of the increasing amount of waste, the dynamics of globalization and urbanization process, waste management is an important issue of ecological policy in highly developed countries. Landfill sites intensify environmental threats for the neighborhood and give rise to toxic substances which impair human health being released from the landfills. These are persistent organic pollutants (POPs, heavy metals and also biological gas, bioaerosols, bacteria and viruses. Scientists have conducted a lot of research to evaluate the impact of landfill sites on human health living in their vicinity. They found increased occurrence of congenital anomalies, increased risk of certain cancers and low birth weight of infants. The results of the studies didn’t deliver absolute proof of relation between the impact of landfill sites on the induction of cancer and other diseases. There is a necessity to conduct further research to evaluate the impact of landfill sites on people health living in the vicinity

  20. Energetic particle fluxes in vicinity of Jupiter's moon Europa

    Podzolko, Mikhail; Getselev, Igor; Gubar, Yuriy; Veselovsky, Igor

    Currently several projects of sending research space vehicles to Jupiter and its Galilean moons in 2020 are being developed. In particular, Russian Space Agency proposed the project of Europa lander. During the mission the spacecraft will be affected by charged particles of various origins. The greatest hazard will originate from powerful Jupiter's radiation belts, especially during the time of spacecraft operation near Europa and on its surface. The absorbed radiation dose during 2 months in Europa's orbit under shielding compared to that for "Galileo" spacecraft will amount to almost 1 megarad, the major contribution to it will originate from relativistic electrons. However, near Europa part of the charged particle flux will be shaded by the moon. Obviously, fluxes of particles of all energies on its surface will be lower by at least 2 times, than in the same point of space without Europa. But furthermore, the reduction of the fluxes in vicinity of Europa is nonuniform, and differs for the surface and the low-altitude orbit. This is caused by several factors: the complexity of particle trajectories near Europa and in Jupiter's magnetosphere in general, difference of Europa's orbital plane from Jupiter's geomagnetic equator plane, certain disturbance of Jupiter's magnetic field in vicinity of Europa, possible influence of electric fields and Europa's tenuous atmosphere. In the current study computations of energetic particle flux distribution near Europa and on its surface are made, taking into account several of the above-mentioned factors.

    2015-01-01

    Predicting and quantifying the capability of mapping orbits in the vicinity of primitive bodies is challenging given the complex orbit geometries that exist and the irregular shape of the bodies themselves. This paper employs various quantitative metrics to characterize the performance and relative effectiveness of various types of mapping orbits including terminator, quasi-terminator, hovering, ping pong, and conic-like trajectories. Metrics of interest include surface area coverage, lighting conditions, and the variety of viewing angles achieved. The metrics discussed in this investigation are intended to enable mission designers and project stakeholders to better characterize candidate mapping orbits during preliminary mission formulation activities. The goal of this investigation is to understand the trade space associated with carrying out remote sensing campaigns at small primitive bodies in the context of a robotic space mission. Specifically, this study seeks to understand the surface viewing geometries, ranges, etc. that are available from several commonly proposed mapping orbits architectures

    Guiding center orbit following code in a tokamak edge geometry is developed which connects straight field line coordinate system (away from the separatrix) and Cartesian coordinate system (in the vicinity of the separatrix) smoothly in the equation of motion. In the presence of magnetic stochasticity charged particles in the closed magnetic field line region can be transported to the open field line region and then hit the divertor plates within several toroidal transits. Our preliminary studies suggest finite heat load both on the inner and outer divertor plates. Energy spectrum of particles reaching the plates (which differs from that of the bulk plasma) as function of imposed magnetic stochasticity, is analyzed. This work is supported by Taiwan MOST 104-2112-M-006-019.

Lo interesante es que el libro no es la respuesta a un llamado a enviar artículos que más o menos se acomoden a unos temas y problemas, sino el resultado de lecturas conjuntas, debates y reflexiones que le permitió compartir a los autores lo que en su momento entendían por historia conceptual y por cultura política. Así, decidieron formular preguntas que no solo dieran cuenta de la semántica histórica sino que además, como lo plantean en la introducción, indagan por las experiencias que alimentaron los sentidos dados a un concepto y las expectativas que despertaron entre quienes lo usaron. Los conceptos a trabajar fueron escogidos, entendiendo que tenían esa calidad precisamente por haber estado en el centro de los debates por el sentido y el significado de los acontecimientos; porque fue con esos conceptos que los contemporáneos reflexionaron y elaboraron las experiencias vividas.

  11. Landsat - SRTM Shaded Relief Comparison, Los Angeles and Vicinity

    Science.gov (United States)

    2002-01-01

    Digital elevation models (DEMs), such as those produced by the Shuttle Radar Topography Mission (SRTM), allow user-controlled visualization of the Earth's landforms that is not possible using satellite imagery alone. This three-view comparison shows Los Angeles, Calif., and vicinity, with a Landsat image (only) on the left, a shaded relief rendering of the SRTM DEM on the right, and a merge of the two data sets in the middle. Note that topographic expression in the Landsat image alone is very subtle due to the fairly high sun angle (63 degrees above the horizon) during the satellite overflight in late morning of a mid-Spring day (May 4, 2001). In contrast, computer generated topographic shading of the DEM provides a pure and bold image of topographic expression with a user specified illumination direction. The middle image shows how combining the Landsat and DEM shaded relief can result in a topographically enhanced satellite image in which the information content of both data sets is merged into a single view.Landsat has been providing visible and infrared views of the Earth since 1972. SRTM elevation data matches the 30-meter (98-foot) resolution of most Landsat images and helps in analyzing the large and growing Landsat image archive, managed by the U.S. Geological Survey (USGS).Elevation data used in this image was acquired by the Shuttle Radar Topography Mission (SRTM) aboard the Space Shuttle Endeavour, launched on Feb. 11, 2000. SRTM used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on the Space Shuttle Endeavour in 1994. SRTM was designed to collect 3-D measurements of the Earth's surface. To collect the 3-D data, engineers added a 60-meter (approximately 200-foot) mast, installed additional C-band and X-band antennas, and improved tracking and navigation devices. The mission is a cooperative project between NASA, the National Imagery and Mapping Agency (NIMA) of the U

    Full Text Available The authors observed the feeding and defecation times of the nymphs of T. melanosoma Martínez, Olmedo & Carcavallo, 1987. Two groups were studied, one maintained under controlled conditions of temperature and humidity, and the other under ambient conditions. There was no significant difference in the number of bloodmeals accomplished by the nymphs of the two groups. Until the fourth instar the nymphs needed less than two bloodmeals to reach the subsequent instar, and only in the fifth instar did they require more than three bloodmeals to reach adulthood. This species demonstrated great avidity to feed; in about 70% of the observed cases the insects initiated feeding in less than one minute. Full engorgement was also reached quickly; more than 70% of the bloodmeals lasted for 5 to 15 minutes. In the first three instars more than 70% of defecation was observed immediately after feeding, demonstrating a good vectorial potential. The differences in the conditions under which the insects were maintained, were insufficient to cause a significant difference in the results observed between the two groups studied.

    Full Text Available En el Instituto de Botánica del Nordeste (IBONE se hallaron valiosos datos inéditos sobre la etnobotánica moqoit que fueron documentados en la década de 1960 en la provincia del Chaco por Raúl Martínez Crovetto. Se propone sistematizar y difundir esta información histórica, contextualizarla espacio-temporal y socioculturalmente y analizar en términos generales los usos asignados a las plantas. Se emplea la metodología propia de la “etnobotánica histórica” que considera a los datos del pasado como una fuente de información primaria. Se registró un total de 400 datos etnobotánicos asignados a 231 especies. El 95% de las plantas resultaron nativas. Las especies con mayor cantidad de usos registrados por Martínez Crovetto fueron P. alba, Copernicia alba, Zea mays, P. nigra, B. serra y Schinus fasciculatus. El 49% de aplicaciones fueron medicinales, el 23% alimenticias y el resto de las categorías utilitarias agrupaba menos del 5% de los datos. Esta valiosa información representa uno de los antecedentes más importantes sobre la etnobotánica moqoit publicados hasta el momento.

  15. Unidirectional lateral nanowire formation during the epitaxial growth of GaAsBi on vicinal substrates

    Collar, Kristen N.; Li, Jincheng; Jiao, Wenyuan; Kong, Wei; Brown, April S.

    2018-01-01

    We report on enhanced control of the growth of lateral GaAs nanowires (NWs) embedded in epitaxial (100) GaAsBi thin films enabled by the use of vicinal substrates and the growth-condition dependent role of Bi as a surfactant. Enhanced step-flow growth is achieved through the use of vicinal substrates and yields unidirectional nanowire growth. The addition of Bi during GaAsBi growth enhances Ga adatom diffusion anisotropy and modifies incorporation rates at steps in comparison to GaAs growth yielding lower density but longer NWs. The NWs grown on vicinal substrates grew unidirectionally towards the misorientation direction when Bi was present. The III/V flux ratio significantly impacts the size, shape and density of the resulting NWs. These results suggest that utilizing growth conditions which enhance step-flow growth enable enhanced control of lateral nanostructures.

    We propose an experimental-based tool for dealing with fluorescence modulation close to nanoparticles for application in studies of fluorophores in the vicinity of gold nanoparticles (AuNPs), typically addressed via theoretical models. We performed a photophysical characterization of fluorophores in the vicinity of AuNPs, showing that correct {Phi}{sub F} determination suffers from a local pH effect, and address the observed radiative enhancement. Our approach is based on the experimental assurance that the reference fluorophores are in the same optical conditions as those of the AuNP-fluorophore conjugates. We demonstrate the relevance for introducing corrections for the inner filter effect and the reabsorption of the emitted light caused by AuNPs. The proposed approach could circumvent the need for theoretical based corrections and allow for more accurate determination of fluorescence emission in the vicinity of gold nanoparticles.

    This paper explores the costs and performance required to deliver a small-sized payload package (CubeSat-sized, for instance) to various transportation nodes en route to Mars and near-Mars destinations (such as Mars moons, Phobos and Deimos). Needed is a contemporary assessment and summary compilation of transportation metrics that factor both performance and affordability of modern and emerging delivery capabilities. The paper brings together: (a) required mass transport gear ratios in delivering payload from Earths surface to the Mars vicinity, (b) the cyclical energy required for delivery, and (c) the affordability and availability of various means of transporting material across various Earth-Moon vicinity and Near-Mars vicinity nodes relevant to Mars transportation. Examples for unit deliveries are computed and tabulated, using a CubeSat as a unit, for periodic near-Mars delivery campaign scenarios.

    In this paper we offer a general view of the life and work of Olayo Diaz Giménez (1810-1885, especially during his stage in the city of Murcia, where he lived from 1862 to his death. The paper is divided into four sections. After providing a biographical account of Olayo Díaz, his work as a teacher is approached, with emphasis on his role in the creation of the Physics Cabinet at the Provincial Institute (Secondary School. The following section highlights his activity in promoting the science of his time through his collaborations in the local newspapers and his involvement in the introduction of evolutionism in Murcia. Finally, we look at his period in charge of the Meteorological Office, with emphasis on both his observations as his book on the weather of Murcia. As a result of our study, Olayo Diaz appears as one of the key-scientists in the Murcia of the XIXth century, and as a typical representative of so-called «intermediate scientists», or those that, without possessing an outstanding work of their own, collaborated decisively to create and maintain the necessary conditions to promote scientific activity in Spain.

    2009-11-01

    In order to control the ion density and energy distribution in the vicinity of plasma sheath independently, the inductively coupled plasma and its glow discharge mechanism in the vicinity of plasma sheath were studied by means of optical emission spectroscopy (OES) under different RF power, different discharge and different substrate DC bias voltage. It was shown that the ion density is higher and the electron temperature is lower in the vicinity of inductively coupled plasma sheath according to the ionic line and atomic line. With changing the discharge pressure and RF power, the spectral characteristics analysis shows that the ion density in the vicinity of plasma sheath linearly increases with the RF power and rises with the pressure under the low pressure. The atomic spectral intensity of low excitation states increases rapidly. The atomic spectral intensity of high excitation states rises slowly and the intensity of ion spectrum increases not obviously. By applying the DC bias voltage to substrate, the intensity of emission spectroscopy was analyzed. The result shows that the intensity of spectra rises with the increase in positive bias voltage, while first reduces then increases with the increase in negative bias voltage, and is the weakest in the case of DC bias at -30 V. This shows that the fast ions and the electrons are the main source of energy for Ar ionization and excitation.

    Full Text Available The levels of non-ionizing radiation (electric and magnetic fields at power frequency, which occur near 110/x kV substations are analyzed in this paper. The results of electric field strength and magnetic flux density measurements in the vicinity of three typical substations of the aforementioned voltage level are shown. With the purpose of estimating the exposure of the population to these fields, the obtained results were compared to the reference maximum levels set for increased sensitivity areas, which amount to 2 kV/m for electric field and 40 μT for magnetic flux density. The objective of the conducted analysis is to reach general conclusions on the levels of electric and magnetic fields, which may occur in the vicinity of the substations mentioned above, and evaluate their compliance with the national regulations on the population protection from non-ionizing radiation.

    The temperature dependence of magnetic anisotropy of ultrathin Fe film with different thickness epitaxially grown on vicinal Si(111) substrate has been quantitatively investigated using the anisotropic magnetoresistance(AMR) measurements. Due to the effect of the vicinal substrate, the magnetic anisotropy is the superposition of a four-fold, a two-fold and a weakly six-fold contribution. It is found that the temperature dependence of the first-order magnetocrystalline anisotropies coefficient follows power laws of the reduced magnetization m(T)(=M(T)/M(0)) being consistent with the Callen and Callen's theory. However the temperature dependence of uniaxial magnetic anisotropy (UMA) shows novel behavior that decreases roughly as a function of temperature with different power law for samples with different thickness. We also found that the six-fold magnetocrystalline anisotropy is almost invariable over a wide temperature range. Possible mechanisms leading to the different exponents are discussed.

  13. Impact of nucleation on step-meandering instabilities during step-flow growth on vicinal surfaces.

    Step-meandering instabilities can manifest during step-flow growth on vicinal surfaces [Bales and Zangwill, Phys. Rev. B 41, 5500 (1990); Pierre-Louis, D'Orsogna, and Einstein, Phys. Rev. Lett. 82, 3661 (1999)]. A phase diagram based on the various growth regimes of a vicinal surface allows us to study the impact of nucleation on these meanders and to predict a meandering instability caused by the nucleation and the coalescence of both islands and steps. Using an accelerated kinetic Monte Carlo method, we find that the coalescence of islands with steps produces large protrusions and deep ripples and that the resulting meandering instability is reinforced by the growth of the islands at almost the same positions from one monolayer to the other. A coarsening phenomenon occurs for the instability wavelength until mounds appear, favored by a large Ehrlich-Schwoebel barrier. Such a meandering instability could be exploited for periodic self-assembly.

    In present work we have investigated magnetostrictive ultrasound generation by spiral magnets in the vicinity of magnetic field induced phase transition from spiral to collinear state. We found that such magnets may generate transverse sound waves with the wavelength equal to the spiral period. We have examined two types of spiral magnetic structures: with inhomogeneous exchange and Dzyaloshinskii–Moriya interactions. Frequency of the waves from exchange-caused spiral magnetic structure may reach some THz, while in case of Dzyaloshinskii–Moriya interaction-caused spiral it may reach some GHz. These waves will be emitted like a sound pulses. Amplitude of the waves is strictly depends on the phase transition speed. Some aspects of microwaves to hypersound transformation by spiral magnets in the vicinity of phase transition have been investigated as well. Results of the work may be interesting for investigation of phase transition kinetics as well, as for various hypersound applications. - Highlights: • Magnetostrictive ultrasound generation by spiral magnets at phase transition (PT) is studied. • Spiral magnets during PT may generate transverse sound with wavelength equal to spiral period. • Amplitude of the sound is strictly depends on the phase transition speed. • Microwave-to-sound transformation in the vicinity of PT is investigated as well.

La narración de los hechos de la historia incaica, en especial aquellos relativos a la conquista española, generaron el mito de la muerte del Inca2, a la cual habrán contribuido colonizados y colonizadores. Durante el siglo XVIII serán numerosas las representaciones teatral-musicales de estos hechos.

    Miniaturization in percutaneous surgery has seen its zenith in microperc. Technological advances have enabled us to treat renal lithiasis through a 4.8 Ch. caliper percutaneous access. According to published literature, the technique is reproducible and when applied to small and medium size renal lithiasis has a high success rate keepin a low complication rate. Its main advantage is the absence of tract dilatation, diminishing the bleeding risk inherent to percutaneous access, postoperative pain and hospital stay. Nevertheless, it presents a series of technical limitations: low maneuverability and versatility, impossible extraction of significant fragments, limited vision and high intrarenal pressure. Does microperc have a place among proven techniques such as SWL, flexible ureteroscopy or minipercutaneous surgery? In our article we try to answer this question by reviewing the available literature, and review all technical features, advantages and limitations of the procedure at the same time.

  6. Telling Tales of War to Teens: Ignacio Martínez de Pisón's Una guerra africana and Morocco as "Open Wound" in the Spanish National Imaginary

    2006-01-01

    Full Text Available Exactly ten years after its traumatic defeat in the Spanish-American War of 1898, Spain appeared to find some compensation for the loss of its last colonies by undertaking the invasion of Morocco in 1908. The enterprise proved difficult when the forces of Abd-el-Krim defeated the Spanish army in the summer of 1921. This terrible loss was metaphorized as an "open wound" and entered the collective imagination by becoming a theme in novels such as José Díaz Fernández's El blocao (1928, Ramón Sender's Imán (1930, and Arturo Barea's series La forja de un rebelde (1941-1944. Known as the "Disaster of Annual," the defeat appeared to be almost forgotten until a series of narratives in the late twentieth and early twenty-first centuries obsessively returned to this particular moment of Spanish history. I focus on how one such narrative, Martínez de Pisón's Una guerra africana (2000, revisits this war as adolescent literature ("novelas juveniles" and within the literary genre of the "novels of the War in Africa," and by so doing, contributes to the articulation of a Spanish collective identity with the historical memory of the feared Moroccan Other.

The wind velocity u10,M (7, at which the concentration on a given place in the surrounding of the pollution source attains a maximal value, is calculated. The relation (8 for a calculation of the place with the maximal concentration for a given class of air stability (Table 1 and 2 and for a given wind velocity is derived. According to equation (3 and Table 3, a thermal capacity of EVO1 and EVO2 is calculated, considering a flat country in the vicinity of the sources (x3 = 0 in relation (1. Subsequently, it is also considered that the wind direction has the direction joining the source and the place of concentration calculation (x2 = 0. The calculations of concentration are performed for the 5th class of air stability. As to this class, favourable conditions for the pollutants dispersion are there. Thus, the maximum concentration is in a relatively small distance from the source with a sharp concentration maximum. As to other classes of the air stability (Table 1 and 2, the maximum concentration is located in larger distances from the source, i.e. about 10 km, as it is considered in Table 4 and 5. The theoretical calculation of NOX concentration in the vicinity of the sources, EVO1 and EVO2, shows (Table 4 and 5 that it does not exceed the allowable limit of 150 µg.m-3.

    Among chemical industries, petroleum refineries have been identified as large emitters of a wide variety of pollutants. Benzene, toluene, ethylbenzene, and xylene (BTEX) form an important group of aromatic volatile organic compounds (VOCs) because of their role in the troposphere chemistry and the risk posed to human health. A very large crude oil refinery of the Baltic States (200,000 bbl/day) is situated in the northern, rural part of Lithuania, 10 km from the town of Mažeikiai (Lithuania). The objectives of this study were: (1) to determine of atmospheric levels of BTEX in the region rural and urban parts at the vicinity of the crude oil refinery; and (2) to investigate the effect of meteorological parameters (wind speed, wind direction, temperature, pressure, humidity) on the concentrations measured. The averaged concentration of benzene varied from 2.12 ppbv in the rural areas to 2.75 ppbv in the urban areas where the traffic was determined to be a dominant source of BTEX emissions. Our study showed that concentration of benzene, as strictly regulated air pollutant by EU Directive 2008/50/EC, did not exceed the limit of 5 ppbv in the region in the vicinity of the crude oil refinery during the investigated period. No significant change in air quality in the vicinity of the oil refinery was discovered, however, an impact of the industry on the background air quality was detected. The T/B ratio (0.50-0.81) that was much lower than 2.0, identified other sources of pollution than traffic.

  10. Monitoring the ordering in biomolecular films on vicinal silicon surfaces by reflectance difference/anisotropy spectroscopy

    2006-05-01

    DNA base molecules, adenine, thymine, guanine, and cytosine may be employed as charge transport molecules in biomolecular electronic devices. Their electronic properties are comparable with those of inorganic wide bandgap materials, e.g. GaN with the absorption onset in the near ultra-violet (UV) range. A recent field effect transistor study based on a modified DNA base revealed that the prototype bio-transistor gives rise to a better voltage gain compared to one based on carbon nanotubes (CNTs) [G. Mauricio, P. Visconti, V. Arima, S. D'Amico, A. Biasco, E. D'Amone, R. Cingolani, R. Rinaldi, Nanoletters 3 (2003) 479]. Here, in situ reflectance difference/anisotropy spectroscopy (RDS/RAS) is employed under ultra-high vacuum (UHV) conditions for monitoring the growth of DNA base molecules on vicinal hydrogen passivated Si(1 1 1) surfaces. Such vicinal substrates consisting of steps and terraces may serves as suitable templates for molecular ordering. Indeed, RDS/RAS measurements reveal information about molecular ordering of DNA bases induced by the density of steps on silicon surfaces. All four molecules, however, behave differently on the vicinal substrates. The first transition dipole moments corresponding to adenine and thymine molecules align mainly perpendicular to the step edge direction while for guanine and cytosine they align parallel to this direction, however, only in very thin layers. The RDS/RAS signal of the guanine and cytosine layers with thicknesses above 20 nm saturates due to a loss of ordering at higher coverages. Additionally, time-resolved RDS/RAS measurements at the silicon E 2 (4.25 eV) critical point (CP) demonstrate the sensitivity to the biomolecular/inorganic interface formation.

    The anisotropy of the spin-orbit interaction, <<{lambda}{sub a}> , in vicinal Co films has been measured using x-ray magnetic linear dichroism (XMLD). A linear increase in <{lambda}{sub a}> with Co step density is found using a new sum rule and represents the first experimental confirmation that XMLD probes the magnetocrystalline anisotropy energy (MAE). X-ray magnetic circular dichroism is used to confirm that the XMLD arises from changes in the local step-edge electronic structure. The XMLD sum rule gives a larger MAE compared to macroscopic values and is discussed with respect to other local probes of the MAE.

    We consider the current-phase relation (CPR) in Josephson junctions with complex insulator-superconductor-ferromagnetic interlayers in the vicinity of the 0-π transition. We find a strong impact of the second harmonic on the CPR of the junctions. It is shown that the critical current can be kept constant in the region of 0-π transition, while the CPR transforms through multivalued hysteretic states depending on the relative values of tunnel transparency and magnetic thickness. Moreover, the CPR in the transition region has multiple branches with distinct ground states.

    The problem of light propagation is treated in a geocentric reference system with the goal of ensuring picosecond accuracy for time transfer techniques using electromagnetic signals in the vicinity of the Earth. We give an explicit formula for a one way time transfer, to be applied when the spatial coordinates of the time transfer stations are known in a geocentric reference system rotating with the Earth. This expression is extended, at the same accuracy level of one picosecond, to the special cases of two way and LASSO time transfers via geostationary satellites.

    New Shell Model calculations for even-even isotopes {sup 104-108}Sn and {sup 106,108}Te, in the vicinity of {sup 100}Sn have been performed. The calculations have been carried out using the windows version of NuShell-MSU. The two body matrix elements TBMEs of the effective interaction between valence nucleons are obtained from the renormalized two body effective interaction based on G-matrix derived from the CD-bonn nucleon-nucleon potential. The single particle energies of the proton and neutron valence spaces orbitals are defined from the available spectra of lightest odd isotopes of Sb and Sn respectively.

    Published and new data for chemical and isotopic samples from wells and springs on Kilauea Volcano and vicinity are presented. These data are used to understand processes that determine the chemistry of dilute meteoric water, mixtures with sea water, and thermal water. Data for well and spring samples of non-thermal water indicate that mixing with sea water and dissolution of rock from weathering are the major processes that determine the composition of dissolved constituents in water. Data from coastal springs demonstrate that there is a large thermal system south of the lower east rift of Kilauea. Samples of thermal water from shallow wells in the lower east rift and vicinity have rather variable chemistry indicating that a number of processes operate in the near surface. Water sampled from the available deep wells is different in composition from the shallow thermal water, indicating that generally there is not a significant component of deep water in the shallow wells. Data for samples from available deep wells show significant gradients in chemistry and steam content of the reservoir fluid. These gradients are interpreted to indicate that the reservoir tapped by the existing wells is an evolving vapor-dominated system.

    China is suffering from severe pollution accidents which may have catastrophic impacts on the local population and environment. Some questions are unclear to local governments and industry operators like "who are vulnerable to the chemical risks?" and "what is the magnitude of vulnerability?". This paper concentrates on exploring the concepts of human vulnerability and the methodology of analyzing human vulnerability to chemical accidents in the vicinity of chemical industry parks. A conceptual model of human vulnerability to chemical accidents is developed, revealing the roots of human vulnerability and emphasizing its role in risk management. A geographical information system (GIS)-based methodology for mapping vulnerability is proposed and applied to the Nanjing Chemical Industry Park in China. By combining physical vulnerability and social vulnerability spatially, the total vulnerability is revealed to better respond to accidents. It is proposed to improve traffic lines and allocation of medical services, and include vulnerability assessment in land-use planning to reduce future risks. In other words, it seems feasible and effective to reveal physical, social and total vulnerability of residents in the vicinity of chemical risk sources. 2010 Elsevier B.V. All rights reserved.

  3. Neutron diffraction analysis of residual strain/stress distribution in the vicinity of high strength welds

    Full Text Available Residual stresses resulting from non homogeneous heat distribution during welding process belong to most significant factor influencing behavior of welded structures. These stresses are responsible for defect occurrence during welding and they are also responsible for crack initiation and propagation at the either static or dynamic load. The significant effect of weld metal chemical composition as well as the effect of fatigue load and local plastic deformation on residual stress distribution and fatigue life have been recognized for high strength steels welds. The changes in residual stress distribution have then positive effect on cold cracking behavior and also on fatigue properties of the welds [1-3]. Several experimental methods, both destructive and non-destructive, such as hole drilling method, X-ray diffraction, neutron diffraction and others, have been used to examine residual stress distribution in all three significant orientations in the vicinity of the welds. The present contribution summarizes the results of neutron diffraction measurements of residual stress distribution in the vicinity of single-pass high-strength-steel welds having different chemical composition as well as the influence of fatigue load and local plastic deformation. It has been observed that the chemical composition of the weld metal has a significant influence on the stress distribution around the weld. Similarly, by aplying both cyclic load or pre-stress load on the specimens, stress relaxation was observed even in the region of approximately 40 mm far from the weld toe.

    This paper describes a new technique employing fluorescent quantum dots as temperature probes for measuring the temperature rise in the proximity of nanoparticles heated by a radio frequency (rf) electromagnetic field. The remote heating of nanoparticles by an rf field is a promising approach to control biological transformations at the molecular level. In principle, the heat dissipated by each nanoparticle might produce a temperature increase in its proximity, facilitating a change in the molecules directly attached to it but not in the others. Although this method has been demonstrated to provide control over biological transformations, the proposed mechanism involves producing and maintaining large temperature differences across small distances, in the range of several degrees Celsius across tens of nanometers. Existing theories for heat generation and transfer in rf heated nanoparticle systems cannot account for these gradients. To better understand the limitations of local heating, the temperature in the vicinity of rf heated nanoparticles was measured. Dilute aqueous suspensions of gold and magnetite nanoparticles were remotely heated by an rf field between 600-800 kHz. Two systems were investigated: a control sample consisting of quantum dots mixed with nanoparticles and a solution of quantum dots covalently linked to nanoparticles. The temperature of the fluorescent probes represents the average temperature in the former and the local temperature in the later. For the experimental conditions employed in this study, the measured temperature rise in the vicinity of rf heated nanoparticles were similar to the average or "bulk" temperature, in agreement with theoretical predictions.

    This work treats the impact of vibrational coherence on the quantum efficiency of a dissipative electronic wave packet in the vicinity of a conical intersection by monitoring the time-dependent wave packet projection onto the tuning and the coupling mode. The vibrational coherence of the wave packet is tuned by varying the strength of the dissipative vibrational coupling of the tuning and the coupling modes to their thermal baths. We observe that the most coherent wave packet yields a quantum efficiency of 93%, but with a large transfer time constant. The quantum yield is dramatically decreased to 50% for a strongly damped incoherent wave packet, but the associated transfer time of the strongly localized wave packet is short. In addition, we find for the strongly damped wave packet that the transfer occurs via tunneling of the wave packet between the potential energy surfaces before the seam of the conical intersection is reached and a direct passage takes over. Our results provide direct evidence that vibrational coherence of the electronic wave packet is a decisive factor which determines the dynamical behavior of a wave packet in the vicinity of the conical intersection.

    Vicinal Ge(001) is the standard substrate for the fabrication of high-performance solar cells by metal-organic vapour phase epitaxy, where growth of the III-V material on single domain Ge surfaces, with a single dimer orientation, minimizes the formation of anti-phase domain defects. Reflectance anisotropy spectroscopy has proved to be a powerful and sensitive optical probe of such anisotropic surface structures, but moving beyond fingerprinting to atomic structure determination from the optical spectra has been held back by the high computational cost. It is shown that an empirical, local-orbital-based hybrid density functional theory approach produces very good agreement between the theory and the experiment for (2 × 1)-As and (2 × 1)-Sb structures grown on vicinal Ge(001). These results, when taken together with previous work on Si interfaces, show that this computationally efficient approach is likely to prove to be an important general technique for determining the structure of anisotropic semiconductor surfaces and interfaces by comparing the experimental and calculated optical spectrum.

    Self-organization is a promising method within the framework of bottom-up architectures to generate nanostructures in an efficient way. The present work demonstrates that self-organization on the length scale of a few to several tens of nanometers can be achieved by a proper combination of a large (organic) molecule and a vicinal metal surface if the local bonding of the molecule on steps is significantly stronger than that on low-index surfaces. In this case thermal annealing may lead to large mass transport of the subjacent substrate atoms such that nanometer-wide and micrometer-long molecular stripes or other patterns are being formed on high-index planes. The formation of these patterns can be controlled by the initial surface orientation and adsorbate coverage. The patterns arrange self-organized in regular arrays by repulsive mechanical interactions over long distances accompanied by a significant enhancement of surface stress. We demonstrate this effect using the planar organic molecule PTCDA as adsorbate and Ag(10 8 7) and Ag(775) surfaces as substrate. The patterns are directly observed by STM, the formation of vicinal surfaces is monitored by high-resolution electron diffraction, the microscopic surface morphology changes are followed by spectro-microscopy, and the macroscopic changes of surface stress are measured by a cantilever bending method. The in situ combination of these complementary techniques provides compelling evidence for elastic interaction and a significant stress contribution to long-range order and nanopattern formation.

    Titanium dioxide finds versatile applications in various technical fields including gas sensing, coatings, pigments, heterogeneous catalysis, photocatalytic degradation of pollutants, and solar cells. TiO2 is found in three main crystallographic phases: rutile, anatase and brookite. Rutile is the thermodynamically most stable form and is considered a model system for basic research. However, anatase TiO2 is often considered to be catalytically more active than rutile for reasons not yet completely understood. In this work, using scanning tunneling microscopy (STM) and low energy electron diffraction (LEED), the structure of the anatase TiO2(5 14) surface, ˜10 vicinal to the -- lowest energy -- (101) plane, has been studied. The surface was found to facet into a structure composed of ridges with a uniform width of 5 lattice units. Based on atomically-resolved STM and electron counting rules, it is proposed that the sides of the ridges are parallel to (1 10) and (112) planes. These sides might be reconstructed to stabilize the microfaceted structure. Vapor-deposited gold shows pronounced clustering between the ridges, indicating a one-dimensional template effect of the vicinal surface, which supports denser and more uniformly sized Au clusters, as compared to the flat (101) surface.

    Theoretical predictions and experimental results for nanosized modification of metal (Au), semiconductor (Si), or dielectric (soda lime glass) substrates using near-electromagnetic field enhancement in the vicinity of gold nanoparticles are presented. The near field properties for the system consisting of an isolated gold nanoparticle or nanoparticle aggregate deposited on the substrates, which is irradiated by electromagnetic wave, are investigated using Finite Difference Time Domain Simulation technique. The influence of the substrate material on the near field distribution characteristics is predicted. The results reveal that the field on the substrate surface is enhanced in the three investigated cases, but its spatial distribution and magnitude depend on the substrate material. In the case of the metal and semiconductor substrate the enhanced near field is strongly localized in the vicinity of the contact point with the particle, in an area with diameter smaller than the particle's one. The intensity of the enhanced field on the glass is more than an order of magnitude lower than the case of using silicon substrate. The properties of the near field on the substrate surface also depend on the particle arrangement. For a two-dimensional gold nanoparticle array, when the particles are closely arrayed, the intensity of the enhanced field on the substrate surface is minimal. With the increase of the interparticle distance the near field intensity increases. The validity of the obtained theoretical results is confirmed experimentally.

    Cd and Pb contents were determined in 699 samples of fruiting bodies of 55 mushrooms species, collected in the period 2000–2007 in the vicinity of the largest Slovenian thermal power plant (the Šalek Valley) and near an abandoned lead smelter (the Upper Meža Valley). The present study is the first regarding lead and cadmium in mushrooms from those exposed areas. Therefore, there was a significant lack of prior data. Among 55 studied mushroom species 36 species are edible and important from an ecotoxicological perspective. However, the remaining non-edible species are important for bioindication and allowed us to compare our results with other studies carried out in other polluted areas in Europe. The highest contents of Cd were found in Agaricus arvensis Schff.: Fr. (117 mg/kg dw) and Agaricus silvicola L.: Fr. (67.9 mg/kg dw), while the highest contents of Pb were found in Macrolepiota procera (Scop.) Singer (53.8 mg/kg dw) and Lycoperdon perlatum Pers. (50 mg/kg dw), respectively. Considering the high contents of both metals in fruiting bodies of edible fungi, together with FAO/WHO directives on tolerable levels of weekly intake of Pb/Cd by humans, it is evident that consumption of some mushroom species originating from both study areas may pose a significant human health risk. A. arvensis Schff.: Fr., A. silvicola L.: Fr. and Cortinarius caperatus (Pers.) Fr. originating from the Šalek Valley, and Armillaria mellea Vahl. P. Kumm., Boletus edulis Bull., L. perlatum Pers., Leccinum versipelle (Fr. and Hök) Snell, and M. procera (Scop.) Singer originating from the Upper Meža Valley should not be consumed at all. Our findings are consistent with some other studies, which emphasized that mushrooms from heavily polluted areas, such as in the vicinity of smelters, accumulate extremely high amounts of metals, and should therefore be omitted from human consumption. - Highlights: ► The Pb contents were higher in saprophytic fungi in comparison with mycorrhizal

    Full Text Available The dynamics of the polar cap boundary and auroral oval in the nightside ionosphere are studied during late expansion and recovery of a substorm from the region between Tromsø (66.6° cgmLat and Longyearbyen (75.2° cgmLat on 27 February 2004 by using the coordinated EISCAT incoherent scatter radar, MIRACLE magnetometer and Cluster satellite measurements. During the late substorm expansion/early recovery phase, the polar cap boundary (PCB made zig-zag-type motion with amplitude of 2.5° cgmLat and period of about 30 min near magnetic midnight. We suggest that the poleward motions of the PCB were produced by bursts of enhanced reconnection at the near-Earth neutral line (NENL. The subsequent equatorward motions of the PCB would then represent the recovery of the merging line towards the equilibrium state (Cowley and Lockwood, 1992. The observed bursts of enhanced westward electrojet just equatorward of the polar cap boundary during poleward expansions were produced plausibly by particles accelerated in the vicinity of the neutral line and thus lend evidence to the Cowley-Lockwood paradigm. During the substorm recovery phase, the footpoints of the Cluster satellites at a geocentric distance of 4.4 RE mapped in the vicinity of EISCAT measurements. Cluster data indicate that outflow of H+ and O+ ions took place within the plasma sheet boundary layer (PSBL as noted in some earlier studies as well. We show that in this case the PSBL corresponded to a region of enhanced electron temperature in the ionospheric F region. It is suggested that the ion outflow originates from the F region as a result of increased ambipolar diffusion. At higher altitudes, the ions could be further energized by waves, which at Cluster altitudes were observed as BBELF (broad band extra low frequency fluctuations.

    In the nearest future, by 2020, about 4% of electricity in Europe will be supplied by sea stations operating from renewable sources: ocean thermal energy, wave and tidal energy, wind farms. By now the wind stations located in the coastal zone, provide the most part of electricity in different European countries. Meanwhile, effects of wind farms on the environment are not sufficiently studied. We report results of laboratory simulations aimed at investigation of hydrodynamic fields arising in the vicinity of wind farm masts under the action of currents and surface waves. The main attention is paid to modeling the resonance effects when the amplitude of velocity pulsations in the vicinity of the masts under the joint action of currents and harmonic waves demonstrate significant growth. This resonance can lead to an increase in Reynolds stress on the bottom, intensification of sediment transport and sound generation. The experiments are performed in the 17 meters hydrodynamical channel of laboratory Morphodynamique Continentale et Côtière UMR CNRS 6143. Mast are modeled by vertical cylinder placed in a steady flow. Behind the cylinder turbulent Karman vortex street occurs. Results are obtained in interval of Reynolds numbers Re=103 - 104(Re=Ud/v, where U is the velocity of the flow, d is diameter of the cylinder, ν is cinematic viscosity). Harmonic surface waves of small amplitude propagating upstream are excited by computer controlled wave maker. In the absence of surface waves, turbulent Karman street with averaged frequency f is observed. It is revealed experimentally that harmonic surface waves with a frequencies closed to 2f can synchronize vortex shedding and increase the amplitude of velocity fluctuations in the wake of the cylinder. Map of regimes is found on the parameter plane amplitude of the surface wave - wave frequency. In order to distinguish the synchronization regimes, we defined phase of oscillations using the Hilbert transform technique. We

El muestreo se efectuó en diciembre 2011, en 19 estaciones oceanográficas de ~55 m de profundidad. Los registros del microperfilador permitieron detectar la formación de escaleras termohalinas que caracterizan la formación de la DDC. Por medio del ángulo de Turner se confirmó que debajo de una capa superficial fuertemente estratificada (7-10 m se registraron eventos de DDC a profundidades entre 15 y 45 m. La DDC fue débil en la mayoría de los registros pero se evidenciaron eventos fuertes entre 15 y 40 m. En la capa subsuperficial, su origen se debió al intercalamiento de las masas aguas estuarinas (aguas frías y menos saladas encima de las oceánicas (aguas más cálidas y saladas, mientras que en la superficie la interacción océano-atmósfera favoreció su ocurrencia. La DDC en conjunto con el viento, las mareas y las ondas internas, puede constituir un mecanismo importante para la mezcla vertical, influenciando los flujos de calor, el hábitat de las especies marinas en estas profundidades y la exportación de carbono hacia los sedimentos.

Comparison was made between the QDs grown on a substrate with a vicinal tilt of 2 in the [111] direction and those on an on-axis substrate. We have studied the evolution of lineshapes of QD photoluminescence spectra under the improved condition of spatial resolution. It was found that the use of a substrate with the vicinal surface leads to the suppression of excitonic PL emitted from a wetting layer. The PL studies revealed that the thermo-stability up to 150 K was obtained in the sample on the on-axis substrate, whereas rapid temperature-induced quenching starting from 6 K was observed in that grown on the vicinal substrate.

    GOES satellite data was used to examine the ageostrophic flow in the vicinity of severe weather outbreaks along the Red River between Texas and Oklahoma in April 1979. The observations were part of the NASA AVE-SESAME I data on atmospheric states close to severe weather conditions. The Barnes Objective Analysis Technique was employed to analyze the data on a 100 km grid. The ageostrophic wind was defined on a regional scale from satellite data on different levels of cloud wind vectors, with a height change signalling a short-wave system in a long-wave trough. The percentage of deviation of the subgeostrophic winds from the geostrophic wind was calculated, and maximum departure corresponded with the region of greatest storm development. Time cross sections of additions to the ageostrophic flow were made as a function of pressure at 100 mb intervals from 900-100 mb. The ageostrophic acceleration was consistently twice the geostrophic acceleration.

    Full Text Available The last three years of archaeological investigations at the site Ru`ana in Banjsko Polje, in the immediate vicinity of Bor, have provided new evidence regarding the role of non-ferrous metallurgy in the economy of the prehistoric communities of north-eastern Serbia. The remains of metallurgical furnaces and a large amount of metallic slags at two neighbouring sites in the mentioned settlement reveal that locations with many installations for the thermal processing of copper ore existed in the Bronze Age. We believe, judging by the finds of material culture, that metallurgical activities in this area also continued into the Iron Age and, possibly, into the 4th century AD.

    2007-10-21

    Based on high-resolution electron energy loss spectroscopy and temperature-programmable desorption, benzene chemisorption on vicinal and nominally flat Si(100) surfaces has been studied for various adsorption, annealing, and site blocking treatments. Three different chemisorbed benzene (C6H6 and C6D6) phases with distinct thermal desorption characteristics and different vibrational spectra have been separated and characterized on both substrates. All three phases are identified as 1,4-cyclohexadiene-like structures with butterfly geometry. Whereas the dominant phase is di-sigma bonded to the two Si atoms of a single Si-Si dimer, the benzene orientation (double bond orientation) in the other phases is rotated. Di-sigma bonding to Si atoms of adjacent Si-Si dimer for the latter cases is most likely. Coverage and temperature dependent conversions between the different phases have been addressed by vibrational spectroscopy.

    A survey of the vascular flora of Yucca Mountain and vicinity, Nye County, Nevada, was conducted from March to June 1994, and from March to October 1995. An annotated checklist of recorded taxa was compiled. Voucher plant specimens were collected and accessioned into the Herbarium at the University of Nevada, Las Vegas. Collection data accompanying these specimens were entered into that herbarium`s electronic data base. Combined results from this survey and the works of other investigators reveal the presence of a total of 375 specific and intraspecific taxa within the area these allocated to 179 genera and 54 families. No taxon currently listed as threatened or endangered under the Endangered Species Act was encountered during this study. Several candidate species for listing under this Act were present, and distributional data for these were recorded. No change in the status of these candidate species is recommended as the result of this study.

    Monitoring of radioactive substances around Finnish nuclear power plants continued in 1993-1994 in accordance with the regular programmes. Some 1000 samples are analysed annually from the terrestrial and aquatic environments of the two power plant sites. Trace amounts of activation products originating from airborne releases from the local power plants were detected in several air, deposition and soil samples. Discharged nuclides were more abundant in the aquatic environment, especially in samples of indicator organisms, sinking matter and sediments. However, the concentrations were so low that they did not significantly increase the radiation burden in the environment. The dominant artificial radionuclides in the vicinity of the power plants remained the cesium isotopes, especially {sup 137}Cs but also {sup 134}Cs, originating from the Chernobyl accident.

    We present a joint experimental-theoretical study of the reflectance anisotropy of clean and gold-covered Si(557), a vicinal surface of Si(111) upon which gold forms quasi-one-dimensional (1D) chains parallel to the steps. By means of first-principles calculations, we analyse the close relationship between the various surface structural motifs and the optical properties. Good agreement is found between experimental and computed spectra of single-step models of both clean and Au-adsorbed surfaces. Spectral fingerprints of monoatomic gold chains and silicon step edges are identified. The role of spin-orbit coupling (SOC) on the surface optical properties is examined, and found to have little effect. (Copyright copyright 2012 WILEY-VCH Verlag GmbH and Co. KGaA, Weinheim)

    Water quality data have been collected since 1974 from established surface and groundwater stations at and in the vicinity of Fenton Hill (Hot Dry Rock Geothermal Demonstration Site) located in the Jemez Mountains. This is part of a continued program of environmental studies. There has been a slight variation in chemical quality of water from the surface and groundwater stations; however, these variations are within normal seasonal fluctuations. Water supply at the site is pumped from the aquifer in the Abiquiu Tuff. Cumulative production from 1976 through 1984 has been 41.5 x 10/sup 6/ gal. The water level in the supply well declined from 365 ft in 1976 to 379 ft in 1984.

    The mechanism of the molybdenum-catalyzed deoxydehydration (DODH) of vicinal diols has been investigated using density functional theory. The proposed catalytic cycle involves condensation of the diol with an Mo(VI) oxo complex, oxidative cleavage of the diol resulting in an Mo(IV) complex, and extrusion of the alkene. We have compared the proposed pathway with several alternatives, and the results have been corroborated by comparison with the molybdenum-catalyzed sulfoxide reduction recently published by Sanz et al. and with experimental observations for the DODH itself. Improved understanding of the mechanism should expedite future optimization of molybdenum-catalyzed biomass transformations. © 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

    2001-07-16

    Two-level magnetic switching of a bilayer epitaxial Fe film grown on a graded stepped W(100) surface is observed using the magneto-optic Kerr effect. Hysteresis loops produced by the film at a location on the curved W(100) surface corresponding to a vicinal angle of 6.4{sup o} exhibit two abrupt jumps in magnetization following spin orientation perpendicular to the steps resulting from surface-step-induced anisotropy. The two-step process can be understood in terms of abrupt depinning of spins in two inequivalent microdomains associated with the stepped surface. The results suggest a new realm of ultrathin film micromagnetics in which characteristic dimensions of 20--30{angstrom} can play a dominant role.

    Coal, like most materials found in nature, contains natural radionuclides and their products in small quantities. Therefore, depending on their concentration in the coal, a coal-fired power plant might potentially contaminate the environment. Indoor Rn-222 concentration in 100 houses located in the vicinity of Yatagan coal-fired power plant in the southwestern part of Turkey were measured using solid state nuclear track detectors. The time-integrated Rn-222 concentrations in the houses ranged from 10 to 120 Bq m{sup -3}. This corresponds to an annual effective dose equivalent ranging from 0.6 to 7/3 mSv. In 96% of the homes, an Rn-222 concentration of 100 Bq m{sup -3} (taken as the limit for future buildings, recommended by ICRP) was not exceeded.

    The possibility of excitation of Surface Plasmon Polaritons (SPP) in the vicinity of the tip of a gold covered optical fiber is investigated when the tip is in the medium with a certain dielectric permittivity. In the experiment the medium was a solution consisting of dimethyl sulfoxide and ethanol liquids in which, as a result of evaporation, a smooth changing of the dielectric permittivity of the solution was taking place. During the evaporation a peak of the power of output radiation was observed from the tip of the fiber, which is explained by the resonant excitation of SPP. This mechanism of SPP excitation in the region of the tip of the optical waveguide opens up new possibilities for increasing the resolution of the nanometric scanning optical microscope and for creation of a new type of optochemical fiber sensors.

    Distribution profiles of marine crenarchaeota group I in the vicinity of deep-sea hydrothermal systems were mapped with culture-independent molecular techniques. Planktonic samples were obtained from the waters surrounding two geographically and geologically distinct hydrothermal systems, and the abundance of marine crenarchaeota group I was examined by 16S ribosomal DNA clone analysis, quantitative PCR, and whole-cell fluorescence in situ hybridization. A much higher proportion of marine crenarchaeota group I within the microbial community was detected in deep-sea hydrothermal environments than in normal deep and surface seawaters. The highest proportion was always obtained from the ambient seawater adjacent to hydrothermal emissions and chimneys but not from the hydrothermal plumes. These profiles were markedly different from the profiles of epsilon-Proteobacteria, which are abundant in the low temperatures of deep-sea hydrothermal environments.

    Full Text Available The following paper will discuss the problems of Eneolithic settlements of Baden and Kostolac culture at Vinča near Belgrade. Eneolithic horizons from Vinča site were scarcely published owing to the fact that both Baden and Kostolac layers are not well stratified because of heavy medieval devastations. In spite of all post-depositional destructions Eneolithic settlements at Vinča show enormous significance for understanding the life of the period, both on the micro and macro-regional scale. At the same time, this work is a sort of an insight into the results of ongoing analysis of material culture and socio-economic patterns of Eneolithic period settlements in Belgrade and its vicinity.

    Vicinal substrates of sapphire with miscut angle of 10 deg. from the (0 0 1) planes towards the [1 1 0] direction have been annealed in air in the range from 1000 to 1500 deg. C. The behaviour of these surfaces has been characterized as a function of the temperature and the thermal treatment time by Atomic Force Microscopy observations. A thermal treatment at 1250 deg. C allows to stabilize a surface made of periodically spaced nanosized step-bunches. Such stepped surfaces were used as template to grow self-patterned epitaxial oxide nanoparticles by thermal annealing of yttria-stabilized zirconia thin films produced by sol-gel dip-coating. Grazing Incidence Small Angle X-ray Scattering and High-Resolution Transmission Electron Microscopy were used to study the morphology of the nanoparticles and their epitaxial relationships with the substrate.

    2017-04-01

    We study the electron dynamics in monocrystalline Cu, Au and Pd surfaces with stepped vicinal structures modeled in a Kronig-Penney scheme. The unoccupied bands of the surface is resonantly excited via the charge transfer interaction of the surface with a moving hydrogen anion. The interaction dynamics are simulated in a quantum mechanical wavepacket propagation approach that used parallel computations. The survival probability of the interacting ion is calculated as well as the electron probability density at all times during the interaction. Animated videos are produced of the electron probability density which show that, when the electron is transferred to the metal, the first two image states are the most likely locations of the electron as it evolves through the superlattice. The survival probability shows peaks at those energies that produce standing waves between the steps on the surface when the electron is in the image state subbands. The work is supported by the XSEDE allocation Grant for high performance computation.

    Multiple approaches have been applied to better understand the characteristics of geologic units exposed at the surface and buried at depth in the vicinity of US Ecology (USE), a low-level commercial waste site in the northern Amargosa Desert, Nevada. Techniques include surficial geologic mapping and interpretation of the subsurface using borehole data. Dated deposits at depth were used to estimate rates of sediment accumulation. The subsurface lithologies have been modeled in three dimensions. Lithologic cross sections have been created from the three-dimensional model and have been compared to resistivity data at the same location. Where deposits appear offset, a fault was suspected. Global Positioning System elevation transects were measured and trenches were excavated to locate a strand of the Carrara Fault. The presence of the fault helps to better understand the shape of the potentiometric surface. These data will be used to better understand the hydrologic parameters controlling the containment of the waste at US Ecology.Quaternary geologic units exposed at the surface, in the vicinity of US Ecology, are derived from the alluvium shed off the adjacent range front and the Amargosa River. These deposits vary from modern to early Pleistocene in age. At depth, heterogeneous sands and gravel occur. Observed in deep trenches and boreholes, the subsurface deposits are characterized as fining-upward sequence of sediment from 5- to 8-meters thick. No volcanic units or fine-grained playa deposits were described in the boreholes to a depth of 200 meters. Based on Infrared Stimulated Luminescence dated core samples, short-term rates of sediment accumulation (Ecology successfully exposed offset Quaternary deposits on a splay of the Carrara Fault. Holocene deposits do not appear to be faulted, however, a fault zone does intersect middle and late Pleistocene aged units.

    1994-10-05

    The primary objective of this research in the vicinity of the proposed Yucca Mountain Nuclear Waste Repository is the detection of episodes of increased runoff and groundwater discharge in this presently arid area. Ancient, inactive spring deposits in nearby valley bottoms (Haynes, 1967; Quade, 1986; Quade and Pratt, 1989), evidence for perennial water in presently dry canyons (Spaulding, 1992), and recent claims for extraordinary increases in precipitation during the last glacial age (Forester, 1994), provide good reason to further investigate both lowland spring-discharge habitats, and upland drainages. The ultimate purpose is to assess the long-term variability of the hydrologic system in the vicinity of Yucca Mountain in response to naturally occurring climatic changes. The data generated in the course of this study are derived from radiocarbon dated packrat (Neotoma) middens. This report presents the results of an initial assessment of the hydrologic stability of the candidate area based on a limited suite of middens from localities that, on geomorphic and hydrologic grounds, could have been close to ancient stream-side or spring environments. Paleoclimatic reconstructions are another means of studying the long-term climatic hydrologic stability of the Candidate Area include, and are also generated from packrat midden data. A different flora characterized the Candidate Area during the last glacial age in response to a cooler and wetter climate, and the plant species that comprised this flora can be used to reconstruct specific components of past climatic regimes. Thus, a secondary objective of this study is to compare the plant macrofossil data generated in this study to other records from the Candidate Area (Spaulding, 1985; Wigand, 1990) to determine if these new data are consistent with prior reconstructions. 66 refs., 4 figs., 13 tabs.

  17. Step density waves on growing vicinal crystal surfaces - Theory and experiment

    2017-01-01

    The Burton, Cabrera and Frank (BCF) theory plays a key conceptual role in understanding and modeling the crystal growth of vicinal surfaces. In BCF theory the adatom concentration on a vicinal surface obeys to a diffusion equation, generally solved within quasi-static approximation where the adatom concentration at a given distance x from a step has a steady state value n (x) . Recently, we show that going beyond this approximation (Ranguelov and Stoyanov, 2007) [6], for fast surface diffusion and slow attachment/detachment kinetics of adatoms at the steps, a train of fast-moving steps is unstable against the formation of steps density waves. More precisely, the step density waves are generated if the step velocity exceeds a critical value related to the strength of the step-step repulsion. This theoretical treatment corresponds to the case when the time to reach a steady state concentration of adatoms on a given terrace is comparable to the time for a non-negligible change of the step configuration leading to a terrace adatom concentration n (x , t) that depends not only on the terrace width, but also on its "past width". This formation of step density waves originates from the high velocity of step motion and has nothing to do with usual kinetic instabilities of step bunching induced by Ehrlich-Schwoebel effect, surface electromigration and/or the impact of impurities on the step rate. The so-predicted formation of step density waves is illustrated by numerical integration of the equations for step motion. In order to complete our previous theoretical treatment of the non-stationary BCF problem, we perform an in-situ reflection electron microscopy experiment at specific temperature interval and direction of the heating current, in which, for the first time, the step density waves instability is evidenced on Si(111) surface during highest possible Si adatoms deposition rates.

    The influence of vicinal sapphire substrates on the growth of N-polar GaN films by metal-organic chemical vapor deposition is investigated. Smooth GaN films without hexagonal surface feature are obtained on vicinal substrate. Transmission electron microscope results reveal that basal-plane stacking faults are formed in GaN on vicinal substrate, leading to a reduction in threading dislocation density. Furthermore, it has been found that there is a weaker yellow luminescence in GaN on vicinal substrate than that on (0001) substrate, which might be explained by the different trends of the carbon impurity incorporation.

    The Nez Perce Tribe Department of Fisheries Resource Management, Watershed Division approaches watershed restoration with a ridge-top to ridge-top approach. The Nez Perce Tribe (NPT) and the Nez Perce National Forest (NPNF) have formed a partnership in completing watershed restoration activities, and through this partnership more work is accomplished by sharing funding and resources in our effort. The Nez Perce Tribe began watershed restoration projects within the Red River Watershed of the South Fork Clearwater River in 2001. Progress has been made in restoring the watershed through road decommissioning and culvert replacement. From completing a watershed assessment to two NEPA efforts and a final stream restoration design, we will begin the effort of restoring the mainstem channel of Red River to provide spawning and rearing habitat for anadromous and resident fish species. Roads have been surveyed and prioritized for removal or improvement as well as culverts being prioritized for replacement to accommodate fish passage throughout the watershed. Another major, and extremely, important component of this project is the Red River Meadow Conservation Easement. We have begun the process of pursuing a conservation easement on approximately 270 acres of prime meadow habitat (Red River runs through this meadow and is prime spawning and rearing habitat).

    We report on the growth of epitaxial Fe1+δ Se0.5Te0.5 thin films on 0°, 5°, 10°, 15° and 20° vicinal cut CaF2 single crystals by pulsed laser deposition. In situ electron and ex situ x-ray diffraction studies reveal a tilted growth of the Fe1+δ Se0.5Te0.5 films, whereby under optimized deposition conditions the c-axis alignment coincides with the substrate [001] tilted axis up to a vicinal angle of 10°. Atomic force microscopy shows a flat island growth for all films. From resistivity measurements in longitudinal and transversal directions, the ab- and c-axis components of resistivity are derived and the mass anisotropy parameter is determined. Analysis of the critical current density indicates that no effective c-axis correlated defects are generated by vicinal growth, and pinning by normal point core defects dominates. However, for H∣∣ab the effective pinning centers change from surface defects to point core defects near the superconducting transition due to the vicinal cut. Furthermore, we show in angular-dependent critical current density data a shift of the ab-planes maxima position with the magnetic field strength.

    2008-01-01

    Ground- and surface-water samples were collected in the vicinity of the Standard Mine in west-central Colorado in order to characterize the local ground-water flow system, determine metal concentrations in local ground water, and better understand factors controlling the discharge of metal-rich waters from the mine. The sampling program included a one-time sampling of springs, mine adits, and exploration pits in Elk Basin and Redwell Basin; repeated sampling throughout one year of Standard Mine Level 1 discharge and Elk Creek near its confluence with Coal Creek; and a one-time sampling of underground sites in Levels 3 and 5 of the Standard Mine. Samples were analyzed for major ions and trace elements, stable isotopes of hydrogen (2H/1H) and oxygen (18O/16O), strontium isotopes, and tritium and dissolved noble gases (including helium isotopes) for tritium/helium-3 age dating. No clear correlations were observed between natural ground-water discharge locations and map-scale faults and lithology. Surface observations and the location of ground-water discharge suggest that simple topography, rather than large-scale geologic features, primarily controls the occurrence and flow of shallow ground water in Elk Basin. Discrete inflows from cross faults or other features were not observed in Levels 3 and 5 of the Standard Mine. Instead, water entered the mine as relatively persistent dripping from gouge and breccia within the Standard fault, which both tunnels follow. Therefore, the Standard fault itself is probably the main pathway of ground-water flow from the shallow subsurface to the mine workings. Low pH (as low as 3.2) and elevated concentrations of zinc, lead, cadmium, copper, and manganese (commonly exceeding water-quality standards for Elk Creek) were measured in samples located within or immediately downgradient of areas where sulfides are abundant, including the Standard fault, the Elk Lode portal, and the breccia pipe in Redwell Basin. Concentrations of these

  2. Characterizing the air quality in the vicinity of a fast-growing Asian airport

    Science.gov (United States)

    Wang, C.; Juang, J.

    2010-12-01

    Many studies have shown that air quality in the vicinity of major airports could be directly influenced by aircraft emissions, airport activities, and other forms of intense transportation in proximity to airports. There are two types of pollutants emitted within the confines of airports: one is directly emitted from aircraft engines, and the other is from ground support equipment (GSE). Such pollutants include aromatic hydrocarbon, ultrafine particles (UFP) , black carbon (BC) , nitrogen oxides, carbon monoxides, and sulfides and could immiately impact the air quality in areas downwind. Although the impact of airport emissions on surrounding communities has been studied in some major airports in North America and Europe, scant attention has been paid to airport pollution issues in Asia despite the surging growth of air travel and of airports. Commercial air traffic in Taiwan has been dramatically growing in the last two decades because of rapid economic growth and is expected to continue surging into the next decades due to increasing trade and travel with China and other countries. In this study, the air quality in the vicinity of Taiwan’s Taoyuan International Airport (TPE Airport) is analyzed to further characterize air quality in the region of a fast-growing Asian airport. Monitoring data from the Taiwanese Environmental Protection Administration (EPA) is used in the study to investigate long-term trends in air quality. The first step of this research is to analyze the data from six stations close to TPE Airport during the last ten years and to filter the attributes (wind field, geography, and so on) which could impact that air quality. Second, we characterize the relationship between data from different monitoring stations by using cluster analysis and then use the air pollution model (Industrial Source Complex-ISC3 and Cal-Puff) to identify why serious pollution events occur. Finally, we use model binds with a GIS system containing population-activity and

  3. Seismic Structure in the Vicinity of the Inner Core Boundary beneath northeastern Asia

    Science.gov (United States)

    Ibourichene, A. S.; Romanowicz, B. A.

    2016-12-01

    The inner core boundary (ICB) separates the solid inner core from the liquid outer core. The crystallization of iron occurring at this limit induces the expulsion of lighter elements such as H, O, S, Si into the outer core, generating chemically-driven convection, which provides power for the geodynamo. Both the F layer, right above the ICB, and the uppermost inner core, are affected by this process so that their properties provide important constraints for a better understanding of core dynamics and, ultimately, the generation and sustained character of the earth's magnetic field. In this study, we investigate the evolution of model parameters (P-velocity, density and quality factor) with depth in the vicinity of the ICB. For this purpose, we combine observations of two body wave phases sensitive to this region: the PKP(DF) phase refracted in the inner core and the PKiKP reflected on the ICB. Variations in the PKP(DF)/PKiKP amplitude ratio and PKP(DF)-PKiKP differential travel times can be related to structure around the ICB. We use waveform data from earthquakes located in Sumatra and recorded by the dense USArray seismic network, which allows us to sample ICB structure beneath northeastern Asia. Observed waveforms are compared to synthetics computed using the DSM method (e.g., Geller et Takeuchi, 1995) in model AK135 (e.g., Montagner & Kennett, 1996) in order to measure amplitude and travel time anomalies. Previous studies (e.g., Tanaka, 1997 ; Cao and Romanowicz, 2004, Yu and Wen, 2006; Waszek and Deuss, 2011) have observed an hemispherical pattern in the vicinity of the ICB exhibiting a faster and more attenuated eastern hemisphere compared to the western hemisphere. The region studied is located in the eastern hemisphere. We find that, on average, travel time anomalies are consistent with previous studies of the eastern hemisphere, however, amplitude ratios are not. We conduct a parameter search for the 1D model that best fits our data. We also consider

  4. Characterization of geologic deposits in the vicinity of US Ecology, Amargosa Basin, southern Nevada

    Taylor, Emily M.

    2010-01-01

    Multiple approaches have been applied to better understand the characteristics of geologic units exposed at the surface and buried at depth in the vicinity of US Ecology (USE), a low-level commercial waste site in the northern Amargosa Desert, Nevada. Techniques include surficial geologic mapping and interpretation of the subsurface using borehole data. Dated deposits at depth were used to estimate rates of sediment accumulation. The subsurface lithologies have been modeled in three dimensions. Lithologic cross sections have been created from the three-dimensional model and have been compared to resistivity data at the same location. Where deposits appear offset, a fault was suspected. Global Positioning System elevation transects were measured and trenches were excavated to locate a strand of the Carrara Fault. The presence of the fault helps to better understand the shape of the potentiometric surface. These data will be used to better understand the hydrologic parameters controlling the containment of the waste at US Ecology. Quaternary geologic units exposed at the surface, in the vicinity of US Ecology, are derived from the alluvium shed off the adjacent range front and the Amargosa River. These deposits vary from modern to early Pleistocene in age. At depth, heterogeneous sands and gravel occur. Observed in deep trenches and boreholes, the subsurface deposits are characterized as fining-upward sequence of sediment from 5- to 8-meters thick. No volcanic units or fine-grained playa deposits were described in the boreholes to a depth of 200 meters. Based on Infrared Stimulated Luminescence dated core samples, short-term rates of sediment accumulation (data, when compared to lithologic cross sections, generally are consistent with lithology grain size and probable soil carbonate accumulations. Surface resistivity displays a fining-upward sequence of sediments at the surface with a soil carbonate imprint. Finally, trenching north of US Ecology successfully exposed

    Cd and Pb contents were determined in 699 samples of fruiting bodies of 55 mushrooms species, collected in the period 2000-2007 in the vicinity of the largest Slovenian thermal power plant (the Šalek Valley) and near an abandoned lead smelter (the Upper Meža Valley). The present study is the first regarding lead and cadmium in mushrooms from those exposed areas. Therefore, there was a significant lack of prior data. Among 55 studied mushroom species 36 species are edible and important from an ecotoxicological perspective. However, the remaining non-edible species are important for bioindication and allowed us to compare our results with other studies carried out in other polluted areas in Europe. The highest contents of Cd were found in Agaricus arvensis Schff.: Fr. (117 mg/kg dw) and Agaricus silvicola L.: Fr. (67.9 mg/kg dw), while the highest contents of Pb were found in Macrolepiota procera (Scop.) Singer (53.8 mg/kg dw) and Lycoperdon perlatum Pers. (50 mg/kg dw), respectively. Considering the high contents of both metals in fruiting bodies of edible fungi, together with FAO/WHO directives on tolerable levels of weekly intake of Pb/Cd by humans, it is evident that consumption of some mushroom species originating from both study areas may pose a significant human health risk. A. arvensis Schff.: Fr., A. silvicola L.: Fr. and Cortinarius caperatus (Pers.) Fr. originating from the Šalek Valley, and Armillaria mellea Vahl. P. Kumm., Boletus edulis Bull., L. perlatum Pers., Leccinum versipelle (Fr. & Hök) Snell, and M. procera (Scop.) Singer originating from the Upper Meža Valley should not be consumed at all. Our findings are consistent with some other studies, which emphasized that mushrooms from heavily polluted areas, such as in the vicinity of smelters, accumulate extremely high amounts of metals, and should therefore be omitted from human consumption.

  7. Infrared spectroscopy of one-dimensional metallic nanostructures on silicon vicinal surfaces

    Energy Technology Data Exchange (ETDEWEB)

    Hoang, Chung Vu

    2010-06-23

    Vicinal silicon(111) surfaces are used as templates for the growth of lead nanowires as well as gold and indium atom chains. The morphology of the Au atom chains was studied by use of Scanning Tunneling Microscopy (STM) and Reflection High Energy Electron Diffraction (RHEED). The In chains were investigated by infrared spectroscopy with the electrical field component of the IR light polarized either parallel or perpendicular to the wires. It is shown that at room temperature, In atom-chains display a plasmonic absorption feature along the chain but not in the perpendicular direction. Furthermore, upon cooling down to liquid nitrogen temperature, a metal to insulator transition is observed. A structural distortion is also confirmed by RHEED. As for the result of Pb nanowires, by means of infrared spectroscopy, it is now possible to control the average length of parallel nanowire arrays by monitoring four experimental parameters that influence on the nucleation density; namely: Pb coverage, evaporation rate, substrate temperature and the surface itself. The system shows an enhancement of the absorption at the antenna frequency in the low temperature regime. This scenario is assigned to the reduction of electron-phonon scattering due to low temperature. (orig.)

    This analysis compares the rates of spontaneous abortion among women living in the vicinity of a lead smelter with those of women living in a town where blood lead levels were low. Data derive from the obstetric histories of both groups of women obtained while seeking prenatal care for a later pregnancy. A total of 639 women (304 exposed, 335 unexposed) had at least one previous pregnancy and lived at the same address since their first pregnancy. The geometric mean blood lead concentrations in the sample at the time of the interviews were 0.77 mumol/L in the exposed town and 0.25 mumol/L in the unexposed town. The rates of spontaneous abortions in first pregnancies were similar, with 16.4 percent of women in the exposed town and 14.0 percent in the unexposed town reporting loss. The adjusted odds ratio relating town of residence to spontaneous abortion was 1.1 (95% CI = 0.9, 1.4). This analysis represents the first systematic attempt to seek an association between environmental lead exposure and spontaneous abortion. As such, the failure to find a positive association strongly suggests that at the levels of exposure represented in our sample, such an association does not exist.

  9. The Bolgary IX settlement – a site of the Ananyino finale in the vicinity of Perm

    2015-06-01

    Full Text Available The article presents materials recovered from the Bolgary IX settlement, attributed to the late Ananyino group of sites, discovered in the vicinity of the city of Perm on the left bank of the Kama River. The structures thus found were interpreted by the authors as, presumably, a dwelling (? and a cult building. The pre-Ananyino cult buildings are well known by two hillforts – Zuevy Klychi-1 on the Lower Kama and Argyzh on the Vyatka River. Small clay figurines, arrow heads, spindle whorls, small oblational cups and household ceramics were found within the cult buildings. Household ceramics are represented by some typical late Ananyino vessel forms: mainly bowls with a closed throat, sometimes with profiled pronounced neck. Some vessels have a collar on the rim. Ornamentation of the vessels includes versatile corded, combed and recessed compositions. The Bolgary IX material culture is considered in complex with simultaneous Protasy burial ground, which is located on a nearby promontory and has similar ceramics among the grave goods. This complex of sites (the settlement and the burial ground is dated back to 3rd-2nd centuries BC and is related by the authors to the period of transition from the Ananyino to the Glyadenovo cultures in the Kama River region.

  10. On the equatorial confinement of thermal plasma generated in the vicinity of the rings of Saturn

    Science.gov (United States)

    Ip, W.-H.

    1984-01-01

    Consideration of the force balance of the ring plasma generated by meteoroid impact in the rotating ionosphere of Saturn is extended to include the magnetic mirroring effect. It is found that there are modifications to the so-called siphon flow limit derived for charged particles with zero magnetic moment if the ionospheric plasma has a thermal temperature exceeding a few electron volts. The nature of the force balance is such that, instead of a sharp division between complete loss and complete reabsorption, a transition zone of partial loss appears. If part of the ions near the rings are produced by ionization of the neutral atmosphere in the vicinity of the ring system (also generated by meteoroid impact vaporization), another theoretical limit dividing the upward flow from the equatorially confined motion is located near the observed boundary between the B ring and the C ring. This new limit is very sharp, as required to explain the B-C ring boundary, which has not yet been explained by gravitational theory.

    Multipole spectral expansion based theory of energy transfer interactions between a donor and an acceptor molecule in the vicinity of a core-shell (nanoshell or core@shell) based plasmonic nanostructure is developed. In view of the diverse applications and rich plasmonic features such as tuning capability of surface plasmon (SP) frequencies, greater sensitivity to the change of dielectric environment, controllable redirection of electromagnetic radiation, closed form expressions for Energy Transfer Rate Enhancement Factor (ETREF) near core-shell particle are reported. The dependence of ETREF on different parameters is established through fitting equations, perceived to be of key importance for developing appropriate designs. The theoretical approach developed in the present work is capable of treating higher order multipoles, which, in turn, are also shown to play a crucial role in the present context. Moreover, closed form expressions derived in the present work can directly be used as formula, e.g., for designing SP based biosensors and estimating energy exchange between proteins and excitonic interactions in quantum dots.

  12. "Killer" Microcapsules That Can Selectively Destroy Target Microparticles in Their Vicinity.

    Science.gov (United States)

    Arya, Chandamany; Oh, Hyuntaek; Raghavan, Srinivasa R

    2016-11-02

    We have developed microscale polymer capsules that are able to chemically degrade a certain type of polymeric microbead in their immediate vicinity. The inspiration here is from the body's immune system, where killer T cells selectively destroy cancerous cells or cells infected by pathogens while leaving healthy cells alone. The "killer" capsules are made from the cationic biopolymer chitosan by a combination of ionic cross-linking (using multivalent tripolyposphate anions) and subsequent covalent cross-linking (using glutaraldehyde). During capsule formation, the enzyme glucose oxidase (GOx) is encapsulated in these capsules. The target beads are made by ionic cross-linking of the biopolymer alginate using copper (Cu(2+)) cations. The killer capsules harvest glucose from their surroundings, which is then enzymatically converted by GOx into gluconate ions. These ions are known for their ability to chelate Cu(2+) cations. Thus, when a killer capsule is next to a target alginate bead, the gluconate ions diffuse into the bead and extract the Cu(2+) cross-links, causing the disintegration of the target bead. Such destruction is visualized in real-time using optical microscopy. The destruction is specific, i.e., other microparticles that do not contain Cu(2+) are left undisturbed. Moreover, the destruction is localized, i.e., the targets destroyed in the short term are the ones right next to the killer beads. The time scale for destruction depends on the concentration of encapsulated enzyme in the capsules.

  13. Variability of cohesive sediment transport in vicinity of Sihwa tidal power plant

    Science.gov (United States)

    Ha, H. K.; Kim, J. W.; Woo, S. B.

    2016-12-01

    To investigate the disturbance of sediment dynamics in the world's largest Sihwa tidal power plant (TPP), two mooring observations have been conducted. The mooring results show that the velocity and suspended sediment concentration (SSC) were significantly disturbed over the various time scales. For the short-term (flood vs. ebb) time scale, the resuspension of bottom sediment is mainly controlled by the strong jet-flow (>2 m s-1) and resultant anticlockwise rotating vortex associated with the artificial discharge. During ebb phase, the strong flow resulted in the suspension of high-concentration near-bed sediment, transporting the suspended sediment seaward. After turning into flood phase, the vortex produced the secondary peaks of the SSC, transporting the suspended sediment toward the Sihwa TPP. The most active suspension of bed sediment predominantly occurred during 1-2 hr immediately after the start of artificial discharge. For the fortnight (spring vs. neap) time scale, the SSC during spring tide was approximately 2-5 times higher than that during neap tide. During the combined period of ebb and spring tides, in particular, the periodic artificial discharge can enhance the responses of SSC in the vicinity of Sihwa TPP.

    The purposes of this report are two-fold: (1) to define the hydrogeologic conditions in the vicinity of the defense waste processing facility (DWPF) and, (2) to evaluate the potential for movement of a concentrated salt-solution waste if released at or near the DWPF. These purposes were accomplished by assembling and evaluating existing hydrogeologic data; collecting additional geologic, hydrologic, and water-quality data; developing a local geologic framework; developing a conceptual model of the local ground-water flow system; and by performing laboratory experiments to determine the mobility of salt-solution waste in surface and near-surface sediments. Although the unconsolidated sediments are about 1000 ft thick in the study area, only the Tertiary age sediments, or upper 300 ft are discussed in this report. The top of the Ellenton Formation acts as the major confining unit between the overlying aquifers in Tertiary sediments and the underlying aquifers in Cretaceous sediments; therefore, the Ellenton Formation is the vertical limit of our hydrogeologic investigation. The majority of the hydrologic data for this study come from monitoring wells at the saltstone disposal site (SDS) in Z Area (fig. 3). No recent water-level data were collected in S Area owing to the removal of S Area monitoring wells prior to construction at the DWPF. 46 refs., 26 figs., 7 tabs.

    A new gravimetric geoid with 1 arc minute spatial resolution has been computed for Alaska and its vicinity, ranging from 49N to 72N in latitude and 172E to 234E in longitude. More than 3 million gravity data collected by NGS (National Geodetic Survey) and other agencies such as NGA (National Geospatial-Intelligence Agency), NRCan (Natural Resources Canada), and DNSC (Danish National Space Center) are gridded into 1'x1' mean gravity anomalies, which are combined with the EGM08 coefficient model, up-to degree and order 2160, by a modified Stokes's Kernel. In addition to the improvement on the spatial resolution, the new gravimetric geoid shows about 3cm precision improvement over EGM08, compared with the geoid heights at 199 GPS leveling benchmarks in this region. Finally, a better than 2cm accurate hybrid geoid model is generated by removing both the systematic errors and the correlated signals in the differences of the gravimetric geoid at these GPS leveling benchmarks, which are modeled by a linear system and a multi-matrix covariance (Roman et. al., 2004) function,respectively.

    We investigate the acceleration of electrons and positrons by magnetic-field-aligned electric fields in the polar funnel of an accreting black hole (BH). Applying the pulsar outer-gap theory to BH magnetospheres, we find that such a lepton accelerator arises in the immediate vicinity of the event horizon due to frame-dragging, and that their gamma-ray luminosity increases with decreasing accretion rate. Furthermore, we demonstrate that the gamma-ray flux is enhanced along the rotation axis by more than an order of magnitude if the BH spin increases from a = 0.90M to a = 0.9999M. As a result, if a ten-solar-mass, almost-maximally rotating BH is located within 3 kpc, when its accretion rate is between 0.005 and 0.01 per cent of the Eddington rate, its high-energy flare becomes detectable with the Fermi/Large Area Telescope, provided that the flare lasts longer than 1.2 months and that we view the source nearly along the rotation axis. In addition, its very high energy flux is marginally detectable with the Cherenkov Telescope Array, provided that the flare lasts longer than a night and that our viewing angle is about 45 deg with respect to the rotation axis.

    In 2007, the California Ocean Protection Council initiated the California Seafloor Mapping Program (CSMP), designed to create a comprehensive seafloor map of high-resolution bathymetry, marine benthic habitats, and geology within the 3-nautical-mile limit of California's State Waters. The CSMP approach is to create highly detailed seafloor maps through collection, integration, interpretation, and visualization of swath sonar data, acoustic backscatter, seafloor video, seafloor photography, high-resolution seismic-reflection profiles, and bottom-sediment sampling data. The map products display seafloor morphology and character, identify potential marine benthic habitats, and illustrate both the surficial seafloor geology and shallow (to about 100 m) subsurface geology. The Hueneme Canyon and vicinity map area lies within the eastern Santa Barbara Channel region of the Southern California Bight. The area is part of the Western Transverse Ranges geologic province, which is north of the California Continental Borderland. Significant clockwise rotation - at least 90° - since the early Miocene has been proposed for the Western Transverse Ranges, and the region is presently undergoing north-south shortening. This geologically complex region forms a major biogeographic transition zone, separating the cold-temperate Oregonian province north of Point Conception from the warm-temperate California province to the south. The map area, which is offshore of the Oxnard plain and west of and along the trend of the south flank of the Santa Monica Mountains, lies at the east end of the Santa Barbara littoral cell, characterized by west-to-east littoral transport of sediment derived mainly from coastal watersheds. The Hueneme Canyon and vicinity map area in California's State Waters is characterized by two major physiographic features: (1) the nearshore continental shelf, and (2) the Hueneme and Mugu Submarine Canyon system, which, in the map area, includes Hueneme Canyon and parts

    Scenario development for the system performance assessment of the Yucca Mountain Site Characterization Project defines a scenario as a well-posed problem connecting an initiating event with radionuclide release to the accessible environment by a logical and physically possible combination or sequence of features, events, and processes. Drawing on the advice and assistance of the Project`s principal investigators (PIs), a collection of release scenarios initiated by the nominal ground-water flow occurring in the vicinity of the potential Yucca Mountain high-level-waste repository is developed and described in pictorial form. This collection of scenarios is intended to provide a framework to assist PIs in recognizing essential field and calculational analyses, to assist performance assessment in providing guidance to site characterization, and to continue the effort to exhaustively identify all features, events, and processes important to releases. It represents a step in the iterative process of identifying what details of the potential site are important for safe disposal. 67 refs.

    Full Text Available In the east and northwest necropoles of Sirmium were discovered painted tombs which were not published until now. Painting in them is from the 4th century. The grave next to the north-west wall of basilica of St. Iraeneus (east necropolis was painted with tied garlands and stem, and partly saved frescoes from the tomb around the basilica of St. Sineros (north-west necropolis point to the conclusion that this is a funeral procession, the scene which is represented in its entirety in the tomb in neighboring Beška. These three tombs belong to the pagan population of Sirmium and its vicinity. On the west wall of the tomb in Mike Antića Street (periphery of the east necropolis is represented the motif of scales with fillings, while on its south and north wall are represented the episodes from Jonah’s cycle. Painting in the tomb shows that the buried person was a Christian. Of Christian character is also the burial in the tomb from the village Čalma, not far from Sirmium. On its longitudinal walls is schematically represented the railing, made of parts between which there were the columns carrying the herms, and which has the symbolical meaning of the “railing of Paradise”.

    Full Text Available Due to deposition of birds’ guano, eggshells or feathers, the vicinity of a large seabirds’ breeding colony is expected to have a substantial impact on the soil’s physicochemical features as well as on diversity of vegetation and the soil invertebrates. Consequently, due to changing physicochemical features the structure of bacterial communities might fluctuate in different soil environments. The aim of this study was to investigate the bacterial assemblages in the Arctic soil within the area of a birds’ colony and in a control sample from a topographically similar location but situated away from the colony’s impact area. A high number of OTUs found in both areas indicates a highly complex microbial populations structure. The most abundant phyla in both of the tested samples were: Proteobacteria, Acidobacteria, Actinobacteria and Chloroflexi, with different proportions in the total share. Despite differences in the physicochemical soil characteristics, the soil microbial community structures at the phylum level were similar to some extent in the two samples. The only share that was significantly higher in the control area when compared to the sample obtained within the birds’ colony, belonged to the Actinobacteria phylum. Moreover, when analyzing the class level for each phylum, several differences between the samples were observed. Furthermore, lower proportions of Proteobacteria and Acidobacteria were observed in the soil sample under the influence of the bird’s colony, which most probably could be linked to higher nitrogen concentrations in that sample.

    The impact of ferrochrome smelter on the contamination of its environment with toxic hexavalent chromium, Cr(VI), was assessed by analyzing smelter dusts, soil, grass and tree barks. For the separation of Cr(VI) from Cr(III), solid samples were treated with 0.1 M Na{sub 2}CO{sub 3} and filtered through hydrophilic PDVF 0.45 {mu}m filter prior to the determination of Cr(VI) by electrothermal atomic absorption spectrometry (ET-AAS). Ferrochrome smelter dust was found to contain significant levels of Cr(VI), viz. 43.5 {mu}g g{sup -1} (cyclone dust), 2710 {mu}g g{sup -1} (fine dust), and 7800 {mu}g g{sup -1} (slimes dust) which exceeded the maximum acceptable risk concentration (20 {mu}g g{sup -1}). The concentration of Cr(VI) in environmental samples of grass (3.4 {+-} 0.2), soil (7.7 {+-} 0.2), and tree bark (11.8 {+-} 1.2) collected in the vicinity of the chrome smelter were higher as compared with the same kind of samples collected from uncontaminated area. The results of the investigation show that ferrochrome smelter is a source of environmental pollution with contamination factors of Cr(VI) ranging between 10 and 50.

    A survey of the vascular flora of Yucca Mountain and vicinity, Nye County, Nevada, was conducted from March to June 1994. An annotated checklist of recorded taxa was compiled. Voucher plant specimens were collected and accessioned into the Herbarium at the University of Nevada, Las Vegas. Collection data accompanying these specimens were entered into that herbarium`s electronic data base. Combined results from this survey and the works of other investigators reveal the presence of a total of 325 specific and intraspecific taxa within the area, these allocated to 162 genera and 53 families. Owing to drought conditions prevalent throughout the area, the annual floristic component was largely absent during the period of study, and it is likely much under-represented in the tabulation of results. No taxon currently listed as threatened or endangered under the Endangered Species Act was encountered during this study. Several candidate species for listing under this Act were present, and distributional data for these were recorded. No change in the status of these candidate species is recommended as the result of this survey.

    Full Text Available A near surface repository for low and intermediate-level short-lived radioactive waste will be built on the Stabatiškės site in the vicinity of Ignalina NPP during decommissioning works. The reservoir can also be used for the waste stored in the temporary repositories of the Ignalina NPP. Engineering and nature protective barriers are used in the repository for radioactive waste, however, radionuclides can spread into the environment, extend in the biosphere and cause (define the external power light exposure of the environment due to the natural and premature (prescheduled degradation of the engineering barriers of the repository. The properties of the soil (acidity, quantity of organic substances, humidity are being investigated for estimating the possible migration and dispersion of radionuclides. The activity of radionuclides in the soil is also estimated before building the repository. Natural and artificial radionuclides make the pollution of the soil, and therefore the accumulation and vertical migration of artificial (137Cs, 60Co and natural (226Ra, 232Th, 40K radionuclides are being researched in the soil on the Stabatiškės site.Article in Lithuanian

    Full Text Available An increasing importance of the social functions of the forest entails the necessity to modify forestry management in a way which would ensure its social acceptance. This mainly concerns those parts of the forest that are “most visible”, in the surroundings of roads, tourist trails, as well as water bodies. The article discusses the importance of view analyses in forest landscaping. On the basis of the adopted methodological assumptions, the assessment of landscape resources of the forest in the vicinity of a water reservoir in the Kielce Forest District (Radom Regional Forest Directorate has been made. Available ortophotomaps and aerial photographs taken by UAVs were used for view analyses together with elevation data collected through airborne laser scanning. The results obtained allow to make recommendations for the protection of the reservoir exposure as well as engineering forest management and silviculture. Consequently, the inclusion of visual analyses into the planning stage enables verification of the quality of forest management plans.

    Lunar Infrared Spectrometer (LIS) is an experiment onboard Luna-Globe (Luna 25) and Luna-Resurce (Luna 27) Russian surface missions. It is a pencil-beam spectrometer to be pointed by a robotic arm of the landing module, and is intended for study of the lunar surface composition in the vicinity of the lander. The instrument’s field of view (FOV) of 1(°) is co-aligned with the FOV (45(°) ) of a stereo TV camera. The spectrometer will provide measurements of selected surface areas in the spectral range of 1.15-3.3 mum. The spectral selection is provided by acousto-optic tunable filter (AOTF), which scans the spectral range sequentially. Electrical command of the AOTF allows selecting the spectral sampling, and permits a random access if needed. The spectral resolution is better than 25 cm (-1) . The instrument’s mass is 1.3 kg. The primary goal of the experiment is to detect the regolith hydration at 3mum, identifying its form from the shape of the spectrum, and to follow its changes during the day/shadow pattern. Also, LIS will allow to study the mineralogical composition from mineral signatures within the spectral range, and will serve for selection of samples to be analyzed by other instruments.

    Land-use planning, as concerns the prevention and limitation of the consequences of possible major accidents from industrial installations, is an essential mechanism for dealing with actual or potential conflicts between sources of risk, such as potentially hazardous industrial developments, and surrounding land-uses. The objective of this paper is to present a decision making methodology that is suitable for assisting urban and spatial planning in the vicinity of hazardous installations and therefore covers the directions of Article 12 of the European Council Directive 96/82/EC (the so-called SEVESO II directive). The proposed methodology was designed to address the particularities of the Greek case, regarding the type and availability of risk and spatial data. It incorporates a broad set of multiple and conflicting criteria that arise in land-use planning decisions, through the application of a well known multi-criteria decision analysis method (ELECTRE TRI). Additionally, it is easy to use (comprised of simple steps) and can be readily incorporated into Geographical Information System based platforms. 2010 Elsevier B.V. All rights reserved.

    Full Text Available Tehran as the biggest city of Iran with a population of more than 10 millions has potentially high pollutant exposures of gas oil and gasoline combustion from vehicles that are commuting in the highways every day. The vehicle exhausts contain polycyclic aromatic hydrocarbons, which are produced by incomplete combustion and can be directly deposited in the environment. In the present study, the presence of polycyclic aromatic hydrocarbons contamination in the collected samples of a western highway in Tehran was investigated. The studied location was a busy highway in Tehran. High performance liquid chromatography equipped with florescence detector was used for determination of polycyclic aromatic hydrocarbons concentrations in the studied samples. Total concentration of the ten studied polycyclic aromatic hydrocarbons compounds ranged from 11107 to 24342 ng/g dry weight in the dust samples and increased from 164 to 2886 ng/g dry weight in the soil samples taken from 300 m and middle of the highway, respectively. Also the average of Σ PAHs was 1759 ng/L in the water samples of pools in parks near the highway. The obtained results indicated that polycyclic aromatic hydrocarbons contamination levels were very high in the vicinity of the highway.

    A laser-induced fluorescence technique for the detection and measurement of ionized barium atoms near the vicinity of an oxide-coated electrode in a low-pressure discharge lamp is presented. Ionized Ba atoms are produced by the ionization of neutral Ba atoms in the electrode fall region of the discharge. Radiation at 455.4 nm obtained from a pulsed dye laser was used to excite Ba ii from the ground state, 62S1/2, to the resonance level, 62P3/2, and the fluorescence radiation at 614.2 nm for the 62P3/2→52D5/2 transition was measured. The number density of Ba ii atoms as determined from the measured intensity of the fluorescence signal (614.2 nm) is dependent on the discharge current, and the polarity of the neighboring electrode. It is found to be larger when it is acting as an anode than when it is a cathode.

    The collection of borehole geophysical logs and images and continuous water-level data was conducted by the U.S. Geological Survey South Atlantic Water Science Center in the vicinity of the GMH Electronics Superfund site near Roxboro, North Carolina, during December 2012 through July 2015. The study purpose was part of a continued effort to assist the U.S. Environmental Protection Agency in the development of a conceptual groundwater model for the assessment of current contaminant distribution and future migration of contaminants. Previous work by the U.S. Geological Survey South Atlantic Water Science Center at the site involved similar data collection, in addition to surface geologic mapping and passive diffusion bag sampling within monitoring wells (Chapman and others, 2013). The continued data compilation efforts included the delineation of more than 900 subsurface features (primarily fracture orientations) in 10 open borehole wells. Geophysical logs, borehole imagery, pumping data, and heat-pulse flow measurements were collected and are presented within this data release.

    During the first months of observations, the Magnetospheric Multiscale Fly's Eye Energetic Particle Spectrometer instrument has observed several instances of electron acceleration up to greater than 100 keV while in the vicinity of the dayside reconnection region. While particle acceleration associated with magnetic reconnection has been seen to occur up to these energies in the tail region, it had not yet been reported at the magnetopause. This study reports on observations of electron acceleration up to hundreds of keV that were recorded on 19 September 2015 around 1000 UT, in the midst of an X-line crossing. In the region surrounding the X-line, whistler-mode and broadband electrostatic waves were observed simultaneously with the appearance of highly energetic electrons which exhibited significant energization in the perpendicular direction. The mechanisms by which particles may be accelerated via reconnection-related processes are intrinsic to understanding particle dynamics among a wide range of spatial scales and plasma environments.

    Tritium is the radioactive isotope of hydrogen. It can be integrated into most biological molecules. Even though its radiotoxicity is weak, the effects of tritium can be increased following concentration in critical compartments of living organisms. For a better understanding of tritium circulation in the environment and to highlight transfer constants between compartments, we studied the tritiation of different agricultural matrices chronically exposed to tritium. Milk is one of the most frequently monitored foodstuffs in the vicinity of points known for chronic release of radionuclides firstly because dairy products find their way into most homes but also because it integrates deposition over large areas at a local scale. It is a food which contains all the main nutrients, especially proteins, carbohydrates and lipids. We thus studied the tritium levels of milk in chronic exposure conditions by comparing the tritiation of the main hydrogenated components of milk, first, component by component, then, sample by sample. Significant correlations were found between the specific activities of drinking water and free water of milk as well as between the tritium levels of cattle feed dry matter and of the main organic components of milk. Our findings stress the importance of the metabolism on the distribution of tritium in the different compartments. Overall, dilution of hydrogen in the environmental compartments was found to play an important role dimming possible isotopic effects even in a food chain chronically exposed to tritium.

  12. Model of spatial distribution of relativistic electron fluxes in vicinity of Jupiter's moon Europa

    Podzolko, Mikhail; Veselovsky, Igor; Getselev, Igor; Gubar, Yury

    This research was made as a part of a project of future space mission to the system of Jupiter, being developed by Russian Federal Space Agency. Currently several mission strategies are being considered, including placing the spacecraft into the low-altitude orbit around Jupiter’s moon Europa and possibly landing on its surface. In the region of Europa’s orbit the spacecraft will be affected by very strong radiation from the Jupiter’s radiation belts. The absorbed dose during 2 months under shielding compared to that for “Galileo” spacecraft will amount to almost 1 megarad. The major contribution to the dose will originate from relativistic electrons. However, near Europa part of the charged particle flux will be shaded by the moon. This reduction of the fluxes is nonuniform, depends on the particle energy and pitch-angle and differs for the surface and the low-altitude orbit. It is caused by a number of factors: complexity of particle trajectories relative to Europa, the flux anisotropy, variations of Europa’s position relative to Jupiter’s magnetic equator plane, magnetic and electric field disturbance in vicinity of Europa, the tenuous atmosphere of the moon. In the current study modeling of relativistic electron flux spatial distribution near Europa and on its surface and computation of the radiation doses have been made, taking into account several of mentioned above factors.

    Water quality data have been collected since 1974 from established surface and groundwater stations at and in the vicinity of Fenton Hill (Hot Dry Rock Geothermal Demonstration Site) located in the Jemez Mountains. This is part of a continuing program of environmental studies. Data on chemical quality of water were determined for samples collected from 13 surface water and 19 groundwater stations in 1985 and 1986. There were slight variations in the chemical quality of the ground and surface water in 1985 and 1986 as compared with previous analyses; however, these variations are within normal seasonal fluctuations. Chemical uptake in soil, roots, and foliage is monitored in the canyon, which receives intermittent effluent release of water from tests in the geothermal circulation loop and occasional fluids from drilling operations. The chemical concentrations found in soil, roots, and vegetation as the result of effluent release have shown a decrease in concentration down-canyon and also have decreased in concentration with time since the larger releases that took place in the late 1970s and early 1980s. 18 refs., 7 figs., 9 tabs.

    The main aim of this study was to evaluate the vulnerability of groundwater to contamination in the vicinity of Ramtha wastewater treatment plant using a modified DRASTIC method in a GIS environment. A groundwater pollution potential map was prepared using modified DRASTIC method by adding lineaments and land use/land cover parameters. The values of the modified DRASTIC index were classified into three categories: low, moderate and high. About 36.5 % of the study area is occupied by the high vulnerability class, 56.5 % is occupied by the moderate vulnerability class and 9 % is occupied by the low vulnerability class. Chemical analysis of the water samples collected from wells distributed in the study area and tapping Umm Rijam aquifer indicated that the nitrate concentration ranges from 20 to 193 mg/L with an average 65.5 mg/L. Nitrate exceeded the permissible limits of WHO and Jordanian standards in 69 and 54 % of the NO3 - samples, respectively. The modified DRASTIC model was validated using nitrate concentration. Results showed a good match between nitrate concentrations level and the groundwater vulnerability classes.

    Potchefstroom and the neighbouring cities rely mostly on the Mooi River and Vaal River for their water needs. These rivers flow through the gold mining areas and farms, and are therefore likely to be contaminated with substantial amounts of inorganic pollutants. Water was collected along the rivers network, streams, canals and dams in Potchefstroom and the vicinity. The samples were characterized for geochemical parameters, metals and anions concentrations. The results showed high concentrations of potentially toxic elements such as As (4.53 mg/L - 5.74 mg/L), Cd (0.25 mg/L - 0.7 mg/L), Pb (1.14 mg/L - 5.13 mg/L) and U (0.04 mg/L - 0.11 mg/L) which were predominantly found around the mining areas. Elevated concentrations of anions such SO42- and CN- were detected around mining areas while NO3- was dominant near farms. The relatively high levels of anions and metals in the surface water made it unfit for domestic or agricultural use. The study showed that contaminants in mining and agricultural facilities were potentially mobilised, thus impacting the nearby water systems.

    We report mesospheric electronic field structure in the vicinity of noctilucent clouds (NLC) and polar mesospheric summer echoes (PMSEs) measured on the DECIMALS-B rocket payload launched during the international rocket-radar campaign NLC-91 from Esrange, Sweden on August 10, 1991. Unusually large vertical E- fields, E(sub Z), about 100-300 mV/m on ascent and greater than 1 V/m on descent were detected at 82.5-84.5 km. The region of the large E(sub Z) was clearly limited by the NLC layer on the bottom and by the distinctly separated PMSE layer on the top. A narrow negative peak in the E(sub Z) height profile observed on ascent in the lower part of the NLC layer was apparently caused by the interaction of the field mill with impacting NLC particles possibly carrying negative charge. If the impact signature is due to single particles, their size is estimated to at least 0.5 microns and their concentration about 10(exp -4)/cu cm locally. Based on the light-scattering properties of NLC such massive particles can only be a minor part of the NLC population.

    Full Text Available Measurements of activity concentrations of natural radionuclides in and around Obajana cement factory, North Central Nigeria have been carried out in this study to determine the activity levels of natural radionuclides in different environmental matrices in order to assess the radiological health hazards associated with the use of these matrices by the local population. A low-background Pb-shielded gamma spectroscopic counting assembly utilizing NaI (Tl detector was employed for the measurements. The results show that sediment samples have the highest activity concentrations of all the radionuclides relative to soil, farmland soil, and rock samples. The radium equivalent activity and indoor gamma dose rates together with the corresponding annual effective indoor doses evaluated were found to be lower than their permissible limits. It suffices to say, that contrary to age-long fear of radiation risks to the population in the vicinity of the cement factory, no excessive radiological health hazards either indoors and/or outdoors is envisaged. Therefore, the environmental matrices around the factory could be used without any restrictions.

    Hydrodeoxygenation of cyclic vicinal diols such as 1,4-anhydroerythritol was conducted over catalysts containing both a noble metal and a group 5-7 transition-metal oxide. The combination of Pd and WOx allowed the removal of one of the two OH groups selectively. 3-Hydroxytetrahydrofuran was obtained from 1,4-anhydroerythritol in 72 and 74% yield over WOx -Pd/C and WOx -Pd/ZrO2 , respectively. The WOx -Pd/ZrO2 catalyst was reusable without significant loss of activity if the catalyst was calcined as a method of regeneration. Characterization of WOx -Pd/C with temperature-programmed reduction, X-ray diffraction, and transmission electron microscopy/energy-dispersive X-ray spectroscopy suggested that Pd metal particles approximately 9 nm in size were formed on amorphous tungsten oxide particles. A reaction mechanism was proposed on the basis of kinetics, reaction results with tungsten oxides under an atmosphere of Ar, and density functional theory calculations. A tetravalent tungsten center (W(IV) ) was formed by reduction of WO3 with the Pd catalyst and H2 , and this center served as the reductant for partial hydrodeoxygenation. © 2014 WILEY-VCH Verlag GmbH & Co.

    Pickup ion detection at Titan is challenging because ion cyclotron waves are rarely detected in the vicinity of the moon. In this work, signatures left by freshly produced pickup heavy ions (m/q ˜ 16 to m/q ˜ 28) as detected in the plasma data by the Cassini Plasma Spectrometer/Ion Mass Spectrometer (CAPS/IMS) instrument on board Cassini are analyzed. In order to discern whether these correspond to ions of exospheric origin, one of the flybys during which the reported signatures were observed is investigated in detail. For this purpose, ion composition data from time-of-flight measurements and test particle simulations to constrain the ions' origin are used. After being validated, the detection method is applied to all the flybys for which the CAPS/IMS instrument gathered valid data, constraining the region around the moon where the signatures are observed. The results reveal an escape region located in the anti-Saturn direction as expected from the nominal corotation electric field direction. These findings provide new constraints for the area of freshly produced pickup ion escape, giving an approximate escape rate of 3.3-2+3×1023 ions· s-1.

    MODIS dark-target (DT) algorithm retrieves aerosol optical depth (AOD) using a Look Up Table (LUT) approach. Global comparison of AOD (Collection 6 ) with ground-based sun photometer gives an Estimated Error (EE) of +/-(0.04 + 10%) over ocean. However, EE does not represent per-retrieval uncertainty. For retrievals that are biased high compared to AERONET, here we aim to closely examine the contribution of biases due to presence of clouds and per-pixel retrieval uncertainty. We have characterized AOD uncertainty at 550 nm, due to standard deviation of reflectance in 10 km retrieval region, uncertainty related to gas (H2O, O3) absorption, surface albedo, and aerosol models. The uncertainty in retrieved AOD seems to lie within the estimated over ocean error envelope of +/-(0.03+10%). Regions between broken clouds tend to have higher uncertainty. Compared to C6 AOD, a retrieval omitting observations in the vicinity of clouds (< or = 1 km) is biased by about +/- 0.05. For homogeneous aerosol distribution, clear sky retrievals show near zero bias. Close look at per-pixel reflectance histograms suggests retrieval possibility using median reflectance values.

    A thorough examination of the results of a time-dependent computer model of a dipole thunderstorm revealed that there are numerous similarities between the time-averaged electrical properties and the steady-state properties of an active thunderstorm. Thus, the electrical behavior of the atmosphere in the vicinity of a thunderstorm can be determined with a formulation similar to what was first described by Holzer and Saxon (1952). From the Maxwell continuity equation of electric current, a simple analytical equation was derived that expresses a thunderstorm's average current contribution to the global electric circuit in terms of the generator current within the thundercloud, the intracloud lightning current, the cloud-to-ground lightning current, the altitudes of the charge centers, and the conductivity profile of the atmosphere. This equation was found to be nearly as accurate as the more computationally expensive numerical model, even when it is applied to a thunderstorm with a reduced conductivity thundercloud, a time-varying generator current, a varying flash rate, and a changing lightning mix.

  2. Turbulent flow in the vicinity of the well during the recovery state

    This paper investigates turbulent flow in the vicinity of the well and focuses on the recovery state. A finite difference solution is developed for transient radially convergent Forchheimer flow to a well based on {Journal of Hydraulic Engineering, 'Approximate Solutions for Forchheimer flow to a well', Mathias S. A., Butler P. A., Zhan H., Sep. 2008}. The implications of turbulence during the recovery state are investigated. Most of the numerical models assume that turbulent head losses dissipate immediately when pumping ends. This approach does not correspond to reality. During the recovery (after the ceasing of pumping) turbulent head losses still continue to exist and there are cases where they can not be assumed negligible. This behaviour can have an important effect to the estimation of the aquifer's parameters based on the analysis of the data during the recovery area. In this paper, the time needed to pass, after the termination of pumping, for the aquifer to reach laminar flow conditions is estimated away from the well-bore to avoid borehole storage effects, based on {'Turbulent Flow to Wells', Dimitriadis P., MSc 'Hydrology for Environmental Management' dissertation, Department of Civil and Environmental Engineering, Imperial College, London, supervisor Dr. A. P. Butler, 2007}. Moreover, a methodology for the estimation of the aquifer's parameters (such as transmissivity, storativity and effective radius) based only in the recovery area is presented for discussion and two step drawdown tests are analyzed and simulated.

    We consider the growth of a vicinal crystal surface in the presence of a step-edge barrier. For any value of the barrier strength, measured by the length ℓES , nucleation of islands on terraces is always able to destroy asymptotically step-flow growth. The breakdown of the metastable step-flow occurs through the formation of a mound of critical width proportional to Lc˜1/ℓES , the length associated to the linear instability of a high-symmetry surface. The time required for the destabilization grows exponentially with Lc . Thermal detachment from steps or islands, or a steeper slope increase the instability time but do not modify the above picture, nor change Lc significantly. Standard continuum theories cannot be used to evaluate the activation energy of the critical mound and the instability time. The dynamics of a mound can be described as a one dimensional random walk for its height k ; attaining the critical height (i.e., the critical size) means that the probability to grow (k→k+1) becomes larger than the probability for the mound to shrink (k→k-1) . Thermal detachment induces correlations in the random walk, otherwise absent.

    Full Text Available There are 18 known pulsating subdwarf B stars in the field of view of the Kepler spacecraft during phase one. The majority of them were observed in the short cadence mode and have been successfully investigated via asteroseismic methods. Since these stars are important for the stellar evolution theory, we performed a search for blue stars in the vicinity of the open cluster NGC 6791, which was observed by the Kepler in the long cadence mode in the so-called super apertures. We used Q1-Q17 LC data and performed pixel analysis using PyKE and our customized scripts. We preliminary tagged 23 objects and we calculated amplitude spectra to look for periodic signal which exist in the data. We found four stars with significant signal in the amplitude spectra with none of them classified as gravity modes in pulsating hot subdwarfs. Likely, all four objects are binaries, though, spectroscopic observations are needed to sort out our hypothesis.

    Full Text Available During Cold War, the region of Eastern Europe was formed by European states that were behind the Iron Curtain.Once the communism has fallen and former Warsaw's Pact members have joined EU in 2004 and 2007 along with the Baltic republics, a New Eastern Europe comprising Ukraine, Republic of Moldova and the Caucasian Republics emerged at the border of EU. The north, west and south maritime frontiers of European Union are opposite with Eastern territorial one that are more difficult to control and defend against asymmetrical threats as: organized crime, drugs traffic, arms proliferation and illegal immigration. this paper aims to demonstrate that EU's policies initiated in the framework of Eastern Partnership (EaP that wanted to bring peace in the Eastern neighborhood did not succeed to fulfill the desired goals. One explanation is that EU did not take in consideration the Russian dream of redesigning its sphere of influence in Eastern Europe. Another one is that the cultural, political and social differences between EU and its EaP partners led to the failure of the project. Thus, European Union's actions toward Eastern vicinity led to a clash between two civilizations: East and West as well as to a geopolitical competition between Russian Federation and EU over their shared neighborhood.

    In response to a request for a cultural resources review from Westinghouse Hanford Company for the Action Plan for Characterization of McGee Ranch Soil, Pacific Northwest Laboratory`s Hanford Cultural Resources Laboratory (HCRL) conducted an archaeological survey of the McGee Ranch vicinity, located in the northwest portion of the Hanford Site. Staff members covered 8.4 km{sup 2} and recorded 42 cultural resources; 22 sites, and 20 isolated artifacts. Only 2 sites and 3 isolates were attributed to a prehistoric Native American occupation. The historic sites date from the turn of the century to the 1940s and are representative of the settlement patterns that occurred throughout the Columbia Basin. In addition to an archaeological pedestrian survey of the project area, we conducted literature and records searches and examined available aerial photographs. Records kept at HCRL were reviewed to determine if any archaeological survey had been conducted previously within the project area. Although no survey had been conducted, portions of the area adjacent to project boundaries were surveyed in 1988 and 1990. During those surveys, historic and prehistoric cultural resources were observed, increasing the possibility that similar land usage had taken place within the current project boundaries. Literature searches established a general historical sequence for this area. Aerial photographs alerted researchers to homesteads and linear features, such as roads and irrigation ditches, that might not be apparent from ground level.

  8. Characterization of the hydrogeology and stress state in the vicinity of the homestake mine, Lead, SD

    Science.gov (United States)

    Ebenhack, Johnathan Foss

    changed the hydrology and stress state in the vicinity of the Homestake mine. Dewatering reduces the hydraulic head and changes the flow systems in the vicinity of the mine. Four major hydrogeologic zones are recognized: 1.) a Shallow Flow System in the upper few hundred meters that dominates recharge and discharge to streams, 2.) a Recharge Capture Zone where water that has entered the region as recharge since mining began is captured by the mine, 3.) a Storage Capture Zone where water from storage in the host rock around the mine is captured, and 4.) a Mine Workings Zone where rock has been removed. Water enters the system at the top of the Shallow Flow System and either discharges to the streams or flows downward and becomes recharge to the lower capture zones. The Recharge Capture Zone grows with time as regions of storage are depleted and new recharge enters, and eventually it is assumed that the entire capture zone for the mine will become the Recharge Capture Zone. Fluxes from the Shallow Flow System to the Recharge Capture Zone typically range from 1x10-9 to 4x10-9 m/s. The largest recharge fluxes from the Shallow Flow System to the Recharge Capture Zone occur above the shallowest portions of the mine. Recharge flux also occurs above areas adjacent to the mine, and when projected to the surface the Recharge Capture Zone creates a roughly elliptical shape that is 6 km x 3.6 km. The Storage Capture Zone extends out beyond and below the Recharge Capture Zone and when projected to the surface creates a roughly elliptical region that is approximately 8.3 km x 6.6 km and extends down to depths of almost 5 km. Hydraulic heads and flow paths have been affected beyond the Storage Capture Zone but this water had not reached the mine by 135 years and therefore these regions are not included in the capture zones. The model was calibrated using in-situ stress data at various points in the mine to improve its ability to estimate the stress state and mechanical deformation

    The airborne immissions in the eastern surroundings to the new Munich airport have been investigated by means of different analytical methods between 1992 and 1995. For a detection of environmental impacts, bioindicators were applied to determine the pollution by PAH and to quantify the pollution by photooxidants. In addition, the PAH content in the upper soil layer was determined. During high pressure weather periods in summer the actual air pollution was invetigated in the course of seven measuring compaigns. The PAH pollution of the soil is typical for rural background sites with highest concentrations in the close vicinity of busy roads, and exhibits no temporary trend. The actual input of PAH does not differ from the typical situation of rural regions in Bavaria at any measuring sites at all. Road traffic can be identified as the main PAH source in summer, whereas the considerably higher pollution in winter can be related to domestic heating. The pollution by photooxidants was found to be rather homogeneous throughout the eastern surroundings to the airport, being lowest at the sites directly influenced by road traffic. The pollution by volatile hydrocarbons at a busy road junction in the city of Erding is considerably higher than in the rural vicinity of the airport. The concentrations exhibit distinct daily courses which, among other things, can be related to atmospheric photooxidation. The hydroperoxides as secondary air pollutants exhibit an inverse course similar to that of ozone, with maximum values in the afternoon. (orig.)

    The area described in this report covers approximately 2,600 square miles in west-central South Carolina and includes the site of the Savannah River Plant, a major production facility of the U.S. Atomic Energy Commission. The climate, surface drainage, and land forms of the study area are typical of the southern part of the Atlantic Coastal Plain. Precipitation is normally abundant and fairly evenly distributed throughout the year, and the mean annual temperature is moderately warm (64?F). The major streams that drain the area (the Savannah, Salkehatchie, and Edisto Rivers) have low gradients and flow in a southeasterly direction toward the Atlantic Ocean. Surface features of the area include narrow, flat-bottomed, steep-sided valleys and broad gently rolling interfluvial areas. Those parts of the Coastal Plain included within the report area can be subdivided into the Aiken Plateau, the Congaree Sandhills, and the Coastal Terraces. The area is underlain by a sequence of unconsolidated and partly consolidated sediments of Late Cretaceous, Tertiary, and Quaternary age. The unconsolidated sediments were deposited unconformably on a basement of igneous and metamorphic rocks of Precambrian and Paleozoic age and sedimentary rocks of Triassic age. The basement rocks are similar to the granite-diorite complex of the Charlotte Belt, the metamorphosed rocks of the Carolina Slate Belt, and the consolidated sediments of the Newark Group. The unconsolidated sediments strike about N. 60 ? E. and dip 6-20 feet per mile to the southeast. They form a wedge-shaped mass that increases in thickness toward the southeast to slightly more than 1,200 feet in the vicinity of Allendale, S.C., on the southeast or downdip side of the study area. The oldest or lowermost unconsolidated sedimentary unit, the Tuscaloosa Formation of Late Cretaceous age, is overlain in the subsurface by beds that are also probably Late Cretaceous in age and that herein are named the Ellenton Formation.

    The Deep Underground Science and Engineering Laboratory (DUSEL) is an underground facility planned for the workings of the former Homestake gold mine in the northern Black Hills, South Dakota. The mine workings cover several km2 in plan and extend to a depth 2.4 km. The area is underlain by Proterozoic metamorphic rocks that were deformed into regional-scale folds whose axes plunge approximately 40o to the SSE. A conceptual model and preliminary numerical analysis of the hydrogeology of the area indicates that permeability depends on effective stress, with values ranging from 0.1 mD at a depth of 2 km to 100 mD at depths of 100m. A deep ground water flow system is contained within a surface-truncated ellipsoid roughly 8 km by 4 km in plan view and 5.5 km deep with its short-axis aligned to the strike of the workings. The deep flow system consists of a zone of relatively rapid flow from the ground surface to the workings overlying the southern part of the mine, and a much larger ellipsoidal zone extending up to several km from the workings where water has been removed from storage. Numerical analyses of the ground water flow and poroelastic deformation in the vicinity of Homestake DUSEL have been refined by sharpening the 3-D resolution of important features. Mine workings have been resolved into three to four major regions where relatively large densities of rock were removed. These mined regions are shaped roughly like plunging ellipsoids with minor axes of several hundred m and major axes up to more than 2 km. They are treated in the simulations as highly permeable regions with an average elastic modulus significantly less than the intact rock; e.g. like soft, permeable inclusions. Recent field investigations and evaluation of the mine database indicate the presence of a relatively large fault that strikes approximately N20W, roughly parallel to the mined out regions. The Homestake fault dips 60NE, cutting the top of one mined region and extending beneath and

    Full Text Available With oil and gas exploration transferring to deeper and more ancient marine strata, more researches have been conducted about the Meso–Neoproterozoic and Cambrian microbial carbonate rocks by petroleum geologists. The Cambrian deposits experienced the first transgression of the Paleozoic, with shallow marine facies depositing in most areas, which are favorable for different kinds of biological reproduction. The Lower Cambrian in Beijing area is lithologically dominated by purple red shales interbedded with limestones, the Middle Cambrian is mainly composed of thick oolitic limestones, and the Upper Cambrian consists of thin limestones and flat-pebble conglomerates. Two beds of microbial carbonate rocks were discovered in the Cambrian outcrops in the vicinity of Beijing. One is from the Zhangxia Formation of Middle Cambrian, and the other is from the Gushan Formation of Upper Cambrian. The microbialites are characterized by combination of multiple stromatolites forming different bioherms. The bioherms are mostly in oval shape and with different sizes, which are 3–4 m long, and 1–3 m high. The surrounding strata beneath the bioherms are oolitic limestones. A central core of flat-pebble conglomerates occurred within each bioherm. Wavy or columnar stromatolites grow on the basis of flat-pebble conglomerates, with dentate erosional surfaces. The bioherm carbonate rocks are interpreted as products from a deep ramp sedimentary environment where potential oil and gas reservoirs can be found. The analysis of sedimentological characteristics of bioherm carbonate rocks and its lithofacies palaeogeography has significant implication for petroleum exploration. Research on geological record of microbialites is beneficial to investigating the Earth evolution, biodiversity, palaeoenvironment and palaeoclimate change, as well as biological extinction event during geological transitions. It also gives warning to human beings of modern biological crisis.

    Hydroboration of dimesitylnorbornenylphosphane with Piers' borane [HB(C6F5)2] gave the frustrated Lewis pair (FLP) 4 in good yield. It has the -PMes2 Lewis base attached at the 2-endo position and the -B(C6F5)2 group 3-exo oriented at the norbornane framework. The vicinal FLP 4 was shown by X-ray diffraction and by spectroscopy to be a rare example of an intramolecular noninteracting pair of a Lewis acid and Lewis base functionality. The FLP 4 rapidly splits dihydrogen heterolytically at ambient temperature to yield the phosphonium/hydrido borate zwitterion 5. It adds to the carbonyl group of benzaldehyde and to carbon dioxide to yield the adducts 6 and 7, respectively. Compounds 5-7 were characterized by X-ray diffraction. Compound 4 adds to the S═O function of sulfur dioxide to give a pair of diastereomeric heterocyclic six-membered ring products due to the newly formed sulfur chirality center, annulated with the norbornane skeleton, which were investigated by (31)P/(11)B single and double resonance solid state NMR experiments. Compound 8 was also characterized by X-ray diffraction. The FLP 4 undergoes a clean N,N-addition to nitric oxide (NO) to give a norbornane annulated five-membered heterocyclic persistent FLP-NO aminoxyl radical 12 (characterized, e.g., by X-ray diffraction and EPR spectroscopy). Additionally, the FLP radical was characterized by (1)H solid state NMR spectroscopy. The radical 12 undergoes a H-atom abstraction reaction with 1,4-cyclohexadiene to yield the respective diamagnetic FLP-NOH product 13, which was also characterized by X-ray diffraction and solid state NMR spectroscopy.

    Full Text Available The structural state of GexSi1-x films grown on Si substrates with the vicinal orientation (1 1 13 has been studied. The (1 1 13 orientation has been obtained by rotating the singular plane (001 around the [1 1 ¯0] axis. The x parameter of GexSi1-x films in different samples ranged from 0.083 to 0.268. Triclinic distortions arising in film crystal lattice have been analyzed using our technique developed for the determination of epitaxial layer structural parameters based on the X-ray diffractometry data. It has been established that during the epitaxial process the film lattice turns around the direction of surface steps due to the introduction of misfit dislocations into the interface. Dislocations with Burgers vector a/2〈110〉 which is not parallel to the interface create an analog of a tilt boundary. The turning angle value ψ is proportional to the misfit dislocation density. This phenomenon is associated with a decrease of the interface symmetry that leads to a change in the efficiency of stress relieving by dislocations belonging to different families. The influence of these families on the low-angle boundary formation is considered. Experimental values of the ψ angle and shear strain for the [13 13 2¯] and [1¯ 1 0] directions lying in the interface (1 1 13 have been defined. A comparison of the experimental and calculated values of ψ for the [13 13 2¯] direction is provided.

    No previous studies have simultaneously measured the biomarkers of environmental exposure and metabolome perturbation in residents affected by industrial pollutants. This study aimed to investigate the metabolic effects of environmental pollutants such as vanadium and polycyclic aromatic hydrocarbons (PAHs) on residents in the vicinity of a petrochemical complex. The study subjects were 160 residents, including 80 high-exposure subjects exposed to high levels of vanadium and PAHs and 80 age- and gender-matched low-exposure subjects living within a 40-km radius of a petrochemical complex. The exposure biomarkers vanadium and 1-hydroxypyrene and four oxidative/nitrosative stress biomarkers were measured in these subjects. Plasma samples from the study subjects were also analyzed using {sup 1}H NMR spectroscopy for metabolic profiling. The results showed that the urinary levels of vanadium and 1-hydroxypyrene in the high-exposure subjects were 40- and 20-fold higher, respectively, than those in the low-exposure subjects. Higher urinary levels of stress biomarkers, including 8-OHdG, HNE-MA, 8-isoPF2α, and 8-NO{sub 2}Gua, were also observed among the high-exposure subjects compared with the low-exposure subjects. Partial least squares discriminant analysis of the plasma metabolome demonstrated a clear separation between the high- and low-exposure subjects; the intensities of amino acids and carbohydrate metabolites were lower in the high-exposure subjects compared with the low-exposure subjects. The exposure to vanadium and PAHs may cause a reduction in the levels of amino acids and carbohydrates by elevating PPAR and insulin signaling, as well as oxidative/nitrosative stress. - Highlights: • Metabolic effects when exposure to pollutants near a petrochemical complex • V and PAHs exposure associated with elevated oxidative/nitrosative stress responses • V and PAHs exposure related to reduced amino acid and carbohydrate levels • V and PAHs affect metabolic

    The objective of this work was to provide a chemical characterization of atmospheric particles collected in the vicinity of a steelmaking industry and to identify the sources that affect PM{sub 10} levels. A total of 94 PM samples were collected in two sampling campaigns that occurred in February and June/July of 2011. PM{sub 2.5} and PM{sub 2.5–10} were analyzed for a total of 22 elements by Instrumental Neutron Activation Analysis and Particle Induced X-ray Emission. The concentrations of water soluble ions in PM{sub 10} were measured by Ion Chromatography and Indophenol-Blue Spectrophotometry. Positive Matrix Factorization receptor model was used to identify sources of particulate matter and to determine their mass contribution to PM{sub 10}. Seven main groups of sources were identified: marine aerosol identified by Na and Cl (22%), steelmaking and sinter plant represented by As, Cr, Cu, Fe, Ni, Mn, Pb, Sb and Zn (11%), sinter plant stack identified by NH{sub 4}{sup +}, K and Pb (12%), an unidentified Br source (1.8%), secondary aerosol from coke making and blast furnace (19%), fugitive emissions from the handling of raw material, sinter plant and vehicles dust resuspension identified by Al, Ca, La, Si, Ti and V (14%) and sinter plant and blast furnace associated essentially with Fe and Mn (21%). - Highlights: • Emissions from steelworks are very complex. • The larger steelworks contribution to PM{sub 10} was from blast furnace and sinter plant. • Sinter plant stack emissions contributed for 12% of the PM{sub 10} mass. • Secondary aerosol from coke making and blast furnace contributed for 19% of the PM{sub 10}. • Fugitive dust emissions highly contribute to PM{sub 10} mass.

    The groundwater flow system in the Culebra Dolomite Member (Culebra) of the Permian Rustler Formation is a potential radionuclide release pathway from the Waste Isolation Pilot Plant (WIPP), the only deep geological repository for transuranic waste in the United States. In early conceptual models of the Culebra, groundwater levels were not expected to fluctuate markedly, except in response to long-term climatic changes, with response times on the order of hundreds to thousands of years. Recent groundwater pressures measured in monitoring wells record more than 25 m of drawdown. The fluctuations are attributed to pumping activities at a privately-owned well that may be associated with the demand of the Permian Basin hydrocarbon industry for water. The unprecedented magnitude of drawdown provides an opportunity to quantitatively assess the influence of unplanned anthropogenic forcings near the WIPP. Spatially variable realizations of Culebra saturated hydraulic conductivity and storativity were used to develop groundwater flow models to estimate a pumping rate for the private well and investigate its effect on advective transport. Simulated drawdown shows reasonable agreement with observations (average Model Efficiency coefficient = 0.7). Steepened hydraulic gradients associated with the pumping reduce estimates of conservative particle travel times across the domain by one-half and shift the intersection of the average particle track with the compliance boundary by more than two kilometers. The value of the transient simulations conducted for this study lie in their ability to (i) improve understanding of the Culebra groundwater flow system and (ii) challenge the notion of time-invariant land use in the vicinity of the WIPP.

    Water-quality data have been collected since 1974 from established surface- and ground-water stations at, and in the vicinity of, Fenton Hill (site of the Laboratory's Hot Dry Rock Geothermal Project). The site is located on the southwest edge of the Valles Caldera in the Jemez Mountains. To determine the chemical quality of water, data were collected in 1987 and 1988 from 13 surface-water stations and 19 ground-water stations. The classification of the water quality is made on the basis of predominated ions and total dissolved solids. There are four classifications of surface water (sodium and chloride, calcium and bicarbonate, calcium and sulfate, and sodium and bicarbonate) and three classifications of ground water (sodium and chloride, calcium and bicarbonate, and sodium and bicarbonate). Variations in the chemical quality of the surface and ground water in 1987 and 1988 are apparent when data are compared with each other and with previous analyses. These variations are not considered significant, as they are in the range of normal seasonal changes. Cumulative production since 1976 from the supply well at Fenton Hill has been about 63 {times} 10{sup 6} gal, with a decline in the water level of the well of about 14 ft, or about 1.4 ft/yr. The aquifer penetrated by the well is still capable of reliable supply to the site for a number of years, based on past production. The quality of water from the well has deteriorated slightly; however, the water quality is in compliance with drinking water standards. The effects of discharge from the storage ponds into an adjacent canyon have been monitored by trace metal analyses of vegetation and soil. The study indicates minimal effects, which will be undetectable in a few years if there are no further releases of effluents into the canyon. 19 refs., 6 figs., 3 tabs.

    Since the arrival of Rosetta at comet 67P, numerous pictures have been delivered by the cameras onboard both the main spacecraft and the Philae lander. They revealed, at the nucleus' surface and inside the walls of the deep pits, few-meters scale repeating structures, thus providing hints about the internal structure of the nucleus, and suggesting that primordial 'cometesimals' may be objects around 3m in size. The CONSERT (Comet Nucleus Sounding Experiment by Radiowave Transmission) experiment is a radar that has been designed to specifically sound the interior of the nucleus and to provide information on the nucleus internal structure. The work presented here is based on the CONSERT data collected during the First Science Sequence (FSS) and marginally during Philae's Separation Descent and Landing (SDL) for comparison. During FFS, the smaller lobe of the nucleus in the vicinity of Abydos has been actually sounded by CONSERT's electromagnetic waves at 90 MHz with a spatial resolution around 10 m. The propagation delays measured during FSS are consistent with a very low bulk permittivity value for the investigated cometary material, which confirms the high porosity of the nucleus. The sharp shape of the received pulses indicates that the electromagnetic waves suffered weak scattering when propagating through the nucleus. This suggests that the sounded part nucleus is thus fairly homogeneous on a spatial scale of tens of meters. We will present further results on the variation of the CONSERT's pulse shape transmitted through the small lobe of the nucleus. For a more accurate analysis and interpretation of the data, we split the FSS data into two distinct sets corresponding to soundings performed West and East of Philae in order to investigate potential differences. Tentative interpretation in terms of nucleus internal structure based on propagation simulations performed in non-homogeneous nucleus numerical models will be presented.

    Continuous-coverage multibeam bathymetric models and sidescan-sonar imagery have been verified with high-resolution seismic-reflection profiles, sediment sampling, and bottom photography. Together these data layers provide detailed base maps that yield topographic, compositional, and environmental perspectives of the sea floor in the vicinity of Woods Hole, an important harbor and major passage between the Elizabeth Islands and Cape Cod, Massachusetts. Tidally dominated high-energy environments within Woods Hole have prevented deposition of Holocene marine sediments, exposed underlying glacial drift of the Buzzards Bay moraine, and winnowed finer grained sediments, leaving lag deposits of boulders and gravel. These conditions have also enlarged and preserved depressions in the moraine surface that were originally kettle holes and formed ebb-tidal deltas at the entrances to passages. Fields of transverse and barchanoid sand waves dominate across the southern part of the study area in Vineyard Sound, where benthic environments are characterized by processes associated with coarse-bedload transport. Transverse sand waves dominate near shoals where sediment supply is greater and have asymmetries that indicate that the shoals are shaped and maintained by clockwise gyres of net sediment transport. Barchanoid sand waves, which are most common where Holocene sediments are thinner, commonly align into elongate fields that have smaller isolated waves concentrated at the eastern ends and that progressively widen and have waveforms that increase in amplitude, wavelength, and complexity westward. The northern, protected parts of the Little and Inner Harbors are characterized by muddy sediment and processes associated with deposition. A pockmark field in Little Harbor and the muddy, organic-rich sediments that form a scarp along the edge of Parker Flat are evidence for the presence of submerged marsh deposits formed during the Holocene rise in sea level.

  3. Concept for the Emergency Protection in the Vicinity of Nuclear Power Plants

    1998-03-01

    In 1991, the Swiss Federal Nuclear Safety Inspectorate (HSK) issued a concept of the regulations for the cloud phase 1 of an nuclear power plant accident in Switzerland valid at that time in co-operation with the Federal Commission for AC Protection (KOMAC) and the Swiss Federal Nuclear Safety Commission (KSA). This concept replaced the version of 1977, which then formed the basis for emergency preparedness in Switzerland. Legal changes, such as the civil protection legislation and the ordinance on the distribution of iodine tablets to the population, as well as experience gained from the emergency exercises necessitated a revision of the existing concept. The present concept is issued by the Federal Commission for AC Protection (KOMAC) and deals with all phases of an accident sequence in a Swiss nuclear power plant focussing on the pre- and cloud phase. It also gives an overview of responsibilities and alert procedures for accidents at foreign nuclear power plants and other nuclear installations, as well as of accidents in connection with transportation of radioactive materials. The concept is designed to help the federal and cantonal authorities in the vicinity of nuclear power plants in charge of emergency protection in preparing their emergency procedure specifications, and in the realisation of the readiness for emergencies. Furthermore, it shall serve the cantons as a guideline for the preparation of emergency specifications for the communities. The concept is based on the assumption that the executive bodies and emergency forces provided for the general civil protection are employed in case of an accident at a nuclear power plant.

    We demonstrate a self-selective metal adsorption and pattern transformation process on vicinal Si(111) surfaces. When Au atoms are deposited onto the self-organized periodic Si(111) surface patterns, the Au atoms self-select to adsorb predominantly onto one of the two distinct domains, the Si(111) terrace or the step-bunched facet at different Au coverage. This leads to a systematic transformation of the surface pattern, whose domain population changes while its periodicity remains intact with the increasing Au coverage. A stress-domain model is used to explain the observed phenomenon. Our findings suggest a unique method for controlled functionalization of surfaces at the nanoscale, as illustrated further by domain-selective self-assembly of uniform CoSi2 nanoclusters on the Au-functionalized vicinal Si(111) surface.

    Full Text Available Amelanotic melanoma (AMM presenting as pyogenic granuloma and occurring in the vicinity of acquired melanocytic nevi is rare. Herein, we report such a manifestation in a 68-year-old male who presented with the painful red nodule and multiple pigmented patches involving the left great toe. Histopathological examination of skin biopsy taken from the nodule with an immunohistochemical study using HMB45 and S-100 confirmed the diagnosis of AMM. Biopsy from the pigmented patch near the nodule showed features of melanocytic nevus. Investigative work up revealed metastatic deposits in the left inguinal lymph node with no evidence of systemic involvement, placing him in malignant melanoma Stage IIIC of American Joint Committee on Cancer (AJCC tumor node metastasis system. The development of AMM in the vicinity of acquired melanocytic nevi and manifesting as granuloma pyogenicum is unique in this case.

    Efficacy of bioassays of "aberrant cells frequency" and "proliferative activity" in root meristem of Allium cepa L. is studied in the present work for a cyto- and genotoxicity assessment of natural waters contaminated with 90Sr and heavy metals in the vicinity of the radioactive waste storage facility in Obninsk, Kaluga region. The Allium-test is shown to be applicable for the diagnostics of environmental media at their combined pollution with chemical and radioactive substances. The analysis of aberration spectrum shows an important role of chemical toxicants in the mutagenic potential of waters collected in the vicinity of the radioactive waste storage facility. Biological effects are not always possible to explain from the knowledge on water contamination levels, which shows limitations of physical-chemical monitoring in providing the adequate risk assessment for human and biota from multicomponent environmental impacts.

    A method for determining magnetic anisotropy parameters of a thin single-crystal film on vicinal (111) substrate as well as substrate miscut angles from angular dependence of ferromagnetic resonance field has been proposed. The method is based on the following: (i) a new approach for the solution of the system of nonlinear equations for equilibrium and resonance conditions; (ii) a new expression of the objective function for the fitting problem. The study of the iron silicide films grown on vicinal Si(111) substrates with different miscut angles confirmed the efficiency of the method. The proposed method can be easily generalized to determine parameters of single-crystal films grown on substrates with an arbitrary cut.

    We study current-induced step bunching and wandering instabilities with subsequent pattern formations on vicinal surfaces. A novel two-region diffusion model is developed, where we assume that there are different diffusion rates on terraces and in a small region around a step, generally arising from local differences in surface reconstruction. We determine the steady state solutions for a uniform train of straight steps, from which step bunching and in-phase wandering instabilities are deduce...

    Thermal pollution from industrial processes can have negative impacts on the spawning and development of cold-water fish. Point sources of thermal effluent may need to be managed to avoid affecting discrete populations. Correspondingly, we examined fine-scale ecological and genetic population structure of two whitefish species (Coregonus clupeaformis and Prosopium cylindraceum) on Lake Huron, Canada, in the immediate vicinity of thermal effluent from nuclear power generation. Niche metrics using δ13C and δ15N stable isotopes showed high levels of overlap (48.6 to 94.5%) in resource use by adult fish captured in areas affected by thermal effluent compared to nearby reference locations. Isotopic niche size, a metric of resource use diversity, was 1.3- to 2.8-fold higher than reference values in some thermally affected areas, indicative of fish mixing. Microsatellite analyses of genetic population structure (Fst, STRUCTURE and DAPC) indicated that fish captured at all locations in the vicinity of the power plant were part of a larger population extending beyond the study area. In concert, ecological and genetic markers do not support the presence of an evolutionarily significant unit in the vicinity of the power plant. Thus, future research should focus on the potential impacts of thermal emissions on development and recruitment.

    A prospective calculation of disease-related social and economic costs due to night-time aircraft noise in the vicinity of Frankfurt/Main airport was performed for the calendar years 2012-2021. It was based on risk estimates for a variety of diagnostic entities (cardiovascular disease, depression, psychosis, diabetes mellitus, dementia and Alzheimer's disease, all cancers except malignancies of the respiratory system) from a previous case-control study on more than 1 million persons enrolled in compulsory sickness funds in the vicinity of the Cologne-Bonn airport, on disease-related cost estimates performed by the German Federal Statistical Office for the calender years 2002-2008, and calculations of the population exposed to night-time aircraft noise in the vicinity of Frankfurt/Main airport (2005 aircraft routes and flight frequencies). Total estimated costs came to more than 1.5 billion € with an excess of 23 400 cases of diseases treated in hospitals and of 3 400 subsequent deaths. © Georg Thieme Verlag KG Stuttgart · New York.

Increasing the lateral range of investigation of VSP (vertical seismic profiling and the calibration of surface seismic profiles with well geological horizons can be improved by combining a surface seismic profile having a specific implementation (with a fixed receiving base called WVP (well vicinity profiling and a vertical seismic profile. In this combined implementation, the drilling rig is immobilized only for the acquisition time of the VSP. The use of a fixed seismic receiving base makes the implementation of the WVP stack light and inexpensive. The results obtained show that the vertical resolutions of the WVP stack and of the VSP are the same. The lateral range of investigation of this mixed implementation is several hundred meters no matter what the depth may be. This methodological research was done in collaboration with Gaz de France.

  19. On the solar origin of interplanetary disturbances observed in the vicinity of the Earth

    Directory of Open Access Journals (Sweden)

    Full Text Available The solar origin of 40 interplanetary disturbances observed in the vicinity of the Earth between January 1997 and June 1998 is investigated in this paper. Analysis starts with the establishment of a list of Interplanetary Mass Ejections or ICMEs (magnetic clouds, flux ropes and ejecta and of Interplanetary Shocks measured at WIND for the period for which we had previously investigated the coupling of the interplanetary medium with the terrestrial ionospheric response. A search for associated coronal mass ejections (CMEs observed by LASCO/SOHO is then performed, starting from an estimation of the transit time of the inter-planetary perturbation from the Sun to the Earth, assumed to be achieved at a constant speed (i.e. the speed measured at 1 AU. EIT/SOHO and Nançay Radioheliograph (NRH observations are also used as proxies in this identification for the cases when LASCO observations do not allow one to firmly establish the association. The last part of the analysis concerns the identification of the solar source of the CMEs, performed using a large set of solar observations from X-ray to radio wavelengths. In the present study, this association is based on a careful examination of many data sets (EIT, NRH and H images and not on the use of catalogs and of Solar Geophysical Data reports. An association between inter-planetary disturbances and LASCO/CMEs or proxies on the disk is found for 36 interplanetary events. For 32 events, the solar source of activity can also be identified. A large proportion of cases is found to be associated with a flare signature in an active region, not excluding of course the involvement of a filament. Conclusions are finally drawn on the propagation of the disturbances in the interplanetary medium, the preferential association of disturbances detected close to the Earth’s orbit with halos or wide CMEs and the location on the solar disk of solar sources of the interplanetary disturbances during that period

  20. Platinum and associated elements at the New Rambler mine and vicinity, Albany and Carbon Counties, Wyoming

    1968-01-01

    Platinum-group metals in the Medicine Bow Mountains were first identified by W. C. Knight in 1901. In the Medicine Bow Mountains, these metals are commonly associated with copper, silver, or gold in shear zones that cut a series of mafic igneous and metamorphic rocks. At the New Rambler mine, where the initial discovery was made, about 50,000 tons of mine and mill waste contain an average of 0.3 percent copper, 7 ppm (parts per million) silver, 1 ppm platinum plus palladium, and 0.7 ppm gold. This material is believed to be from a low-grade envelope around the high-grade pod of complex ore that was mined selectively in the old workings. Soil samples in the vicinity of the New Rambler mine exhibit a wide range of content of several elements associated with the ore. Most of the variation can be attributed to contamination, from the mine workings. Even though soil samples identify a low-level copper anomaly that persists to the limit of the area sampled, soils do not offer a promising medium for tracing mineralization owing to the blanket of transported overburden. Stream sediments, if preconcentrated for analysis, do reveal anomalies not only in the contaminated stream below the New Rambler mine, but in adjacent drainage and on Dave Creek. Examination of a spectrum of elements in heavy-mineral concentrates from stream sediment may contribute to knowledge of the nature of the mineralization and of the basic geology of the environment. The sampling of bedrock exposures is not particularly fruitful because outcrops are sparse and the exposed rocks are the least altered and mineralized. Bedrock sampling does, however, provide information on the large size and provincial nature of the platinum-rich area. We feel that a properly integrated program of geological, geophysical, and geochemical exploration in the Medicine Bow Mountains and probably in the Sierra Madre to the west has a reasonable probability of successfully locating a complex ore body.

    Butanediol dehydrogenase (Bdh1p) from Saccharomyces cerevisiae belongs to the superfamily of the medium-chain dehydrogenases and reductases and converts reversibly R-acetoin and S-acetoin to (2R,3R)-2,3-butanediol and meso-2,3-butanediol, respectively. It is specific for NAD(H) as a coenzyme, and it is the main enzyme involved in the last metabolic step leading to (2R,3R)-2,3-butanediol in yeast. In this study, we have used the activity of Bdh1p in different forms-purified enzyme, yeast extracts, permeabilized yeast cells, and as a fusion protein (with yeast formate dehydrogenase, Fdh1p)-to transform several vicinal diketones to the corresponding diols. We have also developed a new variant of the delitto perfetto methodology to place BDH1 under the control of the GAL1 promoter, resulting in a yeast strain that overexpresses butanediol dehydrogenase and formate dehydrogenase activities in the presence of galactose and regenerates NADH in the presence of formate. While the use of purified Bdh1p allows the synthesis of enantiopure (2R,3R)-2,3-butanediol, (2R,3R)-2,3-pentanediol, (2R,3R)-2,3-hexanediol, and (3R,4R)-3,4-hexanediol, the use of the engineered strain (as an extract or as permeabilized cells) yields mixtures of the diols. The production of pure diol stereoisomers has also been achieved by means of a chimeric fusion protein combining Fdh1p and Bdh1p. Finally, we have determined the selectivity of Bdh1p toward the oxidation/reduction of the hydroxyl/ketone groups from (2R,3R)-2,3-pentanediol/2,3-pentanedione and (2R,3R)-2,3-hexanediol/2,3-hexanedione. In conclusion, Bdh1p is an enzyme with biotechnological interest that can be used to synthesize chiral building blocks. A scheme of the favored pathway with the corresponding intermediates is proposed for the Bdh1p reaction. Copyright © 2016, American Society for Microbiology. All Rights Reserved.

    Based on the data of bottom trawl surveys in the vicinity of Pearl River estuary in August (summer), October (autumn), December (winter) 2006, and April (spring) 2007, the faunal characteristics and distribution pattern of crustaceans were analyzed. A total of 54 species belonging to 25 genera, 17 families, and 2 orders were collected, including 22 species of shrimps, 22 species of crabs, and 10 species of squills. Most of the crustaceans were tropical-subtropical warm-water species, a few of them were eurythermal species, and no warm-water and cold-water species occurred. Euryhaline species were most abundant, followed by halophile species, and the low-salinity species were the least. Most of the crustacean species belonged to the fauna of Indian Ocean-western Pacific Ocean. The faunal assemblages were closer to those of the East China Sea, Philippine Sea, Indonesia Sea, and the Japan Sea, and estranger with those of the Yellow Sea, Bohai Sea, and Korea Sea. The dominant species were Metapenaeus joyner, Oratosquilla oratoria, Charybdis miles, Portunus sanguinolentus, Harpiosquilla harpax, Charybdis feriatus, Charybdis japonica, Oratosquilla nepa, Solenocera crassicornis, Portunus trituberculatus, and Calappa philargius. The crustaceans had the largest species number (33) in autumn and the least one (26) in spring, and the highest stock density at the water depth of < 40 m, especially at 10-20 m. The average stock density of the crustaceans was estimated to be 99.60 kg x km(-2), with the highest (198.93 kg x km(-2)) in summer and the lowest (42.35 kg x km(-2)) in spring. Of the 3 species groups, crabs had the highest stock density (41.81 kg x km(-2)), followed by shrimps (38.91 kg x km(-2)), and squills (18.88 kg x km(-2)). The stock densities of the 3 species groups showed an obvious seasonal variation. Shrimps had the highest stock density (120.32 kg x km(-2)) in summer and the lowest density (0.67 kg x km(-2)) in spring, while crabs and squills had the highest

    Los Angeles and vicinity seen from space, as viewed by the Landsat 7 satellite from an altitude of 437 miles on May 4, 2001. North is at the top. Topographic shading has been enhanced using an elevation data set acquired by the Space Shuttle Endeavour in February 2000. Downtown Los Angeles is just south of the image center, with L.A. and Long Beach harbors to the south, Santa Monica Bay to the west, San Fernando Valley to the northwest, San Gabriel Valley to the east, and Orange County to the southeast. The San Andreas fault forms the straight diagonal mountain front bordering the Mojave Desert at the top of the image. At full resolution, features on the ground as small as 15 meters (49 feet) across can be distinguished, including street patterns and large buildings, as well as boats and their wakes on the ocean. More than ten million people live within this scene.This image was generated by first geographically matching the Landsat scene to a Shuttle Radar Topography Mission (SRTM) elevation model. A measure of topographic slope along a southeast-northwest trend was then calculated, such that southeast facing slopes appear bright and northwest facing slopes appear dark. This slope image was then added to the enhanced Landsat scene in order to intensify the appearance of topography. Topographic shading was subtle in the original Landsat scene due to the fairly high sun angle (63 degrees above the horizon) during the satellite overflight in late morning of a mid-Spring day.Landsat has been providing visible and infrared views of the Earth since 1972. SRTM elevation data matches the 30-meter (98-foot) resolution of most Landsat images and helps in analyzing the large and growing Landsat image archive, managed by the U.S. Geological Survey (USGS).Elevation data used in this image was acquired by the Shuttle Radar Topography Mission (SRTM) aboard the Space Shuttle Endeavour, launched on Feb. 11, 2000. SRTM used the same radar instrument that comprised the Spaceborne

    Populations living in the vicinity of oil refinery sludge deposition sites may be at greater risk of potential exposure to polycyclic aromatic hydrocarbons (PAHs) through inhalation, ingestion, and direct contact with contaminated media. Three Indian oil refinery sludge deposition sites (at Haldia, Barauni and Guwahati) were chosen for study. Soil samples were collected from three different locations at each site. Mild solvent extraction by butanol and exhaustive extraction by acetone/hexane have been conducted to estimate the bioaccessible PAHs beside the total extractable PAHs content of the soil samples. Concentrations of 13 PAHs in the soils were found to be in a range of 67.02-95.21μg/g and bioaccessible PAHs were in a range of 19.296-36.657μg/g. A probabilistic health risk assessment with bioaccessibility considerations was carried out using Monte Carlo simulations for the estimation of the cancer risk exposed to the PAHs. The 90th percentiles cancer risks with bioaccessibility considerations of soil PAHs for children is 6.506E-05 and for the adults the risk is 6.609E-05. Risk assessments on extracted PAHs from exhaustive solvent extraction can overestimate the risk by 2.87-2.89 folds at 90% confidence level with respect to the biomimetic mild extraction procedure using butanol. According to USEPA above 1×10(-6) extra risk of cancer is an alarm towards management. So, public health issues due to PAHs is imminent in these oil refinery vicinity areas. Sensitivity analysis revealed exposure duration (ED) and relative skin adherence factor for soil (AF) as the most influential parameters of the assessment. The profiling and risk assessment study with bioaccessibility considerations of PAHs from soil indicates that high PAHs concentration can lead to higher cancer risk for the vicinity area residents and local government should take immediate management actions.

  15. Odd-parity superconductivity in the vicinity of inversion symmetry breaking in spin-orbit-coupled systems

    Science.gov (United States)

    Kozii, Vladyslav; Fu, Liang; Massachusetts institute of technology Team

    We study superconductivity in spin-orbit-coupled systems in the vicinity of inversion symmetry breaking. We find that due to the presence of spin-orbit coupling, fluctuations of the incipient parity-breaking order generate an attractive pairing interaction in an odd-parity pairing channel, which competes with the s-wave pairing. We show that Coulomb repulsion or an external Zeeman field suppresses the s-wave pairing and promotes the odd-parity superconducting state. Our work provides a new mechanism for odd-parity pairing and opens a route to novel topological superconductivity. This work is supported by the David and Lucile Packard foundation.

    The multi-nucleon transfer reaction mechanism was used to produce and study nuclei in the vicinity of 208Pb. This mass region is a test case for the nuclear shell model. The mass identification of the fragments was performed with the large acceptance magnetic spectrometer VAMOS++ coupled to the AGATA γ-tracking array. This experiment aimed to determine both lifetimes and gyromagnetic ratios of excited states with the Cologne plunger device. The analysis indicates promising results with the possibility to determine several new lifetimes in this region.

    The U.S. Geological Survey monitored water levels in wells in the vicinity of the Waste Isolation Pilot Plant, a storage facility constructed in bedded salts in which defense-associated transuranic wastes will be deposited, in southeastern New Mexico during 1977 to 1985. A variety of methods was used to measure water levels. The particular method utilized at a given time depended on several factors, including the amount of condensation in the well, well-head configuration, depth to water, rate of water level change, and availability of equipment. The five methods utilized were: air line, Lynes pressure sentry system, M-scope, steel tape, and winch. (Lantz-PTT)

    Full Text Available The export of phytal material from the eutrophic Szczecin Lagoon into the Pomeranian Bay creates excellent trophic conditions forthe local benthic fauna in the vicinity of the mouth of the river Swina, where the bottom macrofauna is abundant but highly variable.The changes in the bottom macrofauna biomass of selected taxa, chlorophyll a and nutrient concentrations were tested for associations. The biomasses of selected taxa varied in significant concordance, which suggests that these changes have common causes.Despite the importance of trophic enrichment to faunal abundance, no relationships between faunal biomass and chlorophyll a concentration changes were established. The presence of organic matter enables macrofauna to attain a high biomass, but populationfluctuations are controlled by numerous factors. The significant relationship between the changes in the annual averagephosphate levels and chlorophyll a concentrations in the Szczecin Lagoon indicates the importance of this nutrient to primaryproduction processes in the Lagoon and to the trophic conditions for benthic macrofauna in the vicinity of the Swina mouth.

    As part of a multidisciplinary program to assess the potential long-term impacts of offshore oil and gas exploration and production activities in the Gulf of Mexico, sediment chemical analyses and porewater toxicity tests were conducted in the vicinity of five offshore platforms. Based on data from sea urchin fertilization and embryological development assays, toxicity was observed near four of the five platforms sampled; the majority of the toxic samples were collected within 150 m of a platform. There was excellent agreement among the results of porewater tests with three different species (sea urchin embryological development, polychaete reproduction, and copepod nauplii survival). The sediment concentrations of several metals were well in excess of sediment quality assessment guidelines at a number of stations, and good agreement was observed between predicted and observed toxicity. Porewater metal concentrations compared with EC50, LOEC, and NOEC values generated for water-only exposures indicated that the porewater concentrations for several metals were high enough to account for the observed toxicity. Results of these studies utilizing highly sensitive toxicity tests suggest that the contaminant-induced impacts from offshore platforms are limited to a localized area in the immediate vicinity of the platforms.

    To ascertain solid tumor mortality in towns near Spain's four nuclear power plants and four nuclear fuel facilities from 1975 to 1993, we conducted a mortality study based on 12,245 cancer deaths in 283 towns situated within a 30-km radius of the above installations. As nonexposed areas, we used 275 towns lying within a 50- to 100-km radius of each installation, matched by population size and sociodemographic characteristics (income level, proportion of active population engaged in farming, proportion of unemployed, percentage of illiteracy, and province). Using log-linear models, we examined relative risk for each area and trends in risk with increasing proximity to an installation. The results reveal a pattern of solid-tumor mortality in the vicinity of uranium cycle facilities, basically characterized by excess lung [relative risk (RR) 1.12, 95% confidence interval (CI), 1.02-1.25] and renal cancer mortality (RR 1.37, 95% CI, 1.07-1.76). Besides the effects of natural radiation, these results could well be evincing the influence on public health exerted by the environmental impact of mining. No such well-defined pattern appeared in the vicinity of nuclear power plants. Monitoring of cancer incidence and mortality is recommended in areas surrounding nuclear fuel facilities and nuclear power plants, and more specific studies are called for in areas adjacent to installations that have been fully operational for longer periods. In this regard, it is important to use dosimetric information in all future studies.

    Snow-cap can be used as a simple and effective indicator of industrial air pollution. In this study snow-cap samples were collected from 11 sites located in the vicinity of an oil refinery in Mazeikiai, a region in the north-west of Lithuania, in the winter of 2011. Analysis of snowmelt water and snow-dust was used to determine anthropogenic pollutants such as: sulphates and chlorides, nitrites, nitrates, ammonium nitrogen, total carbon, total nitrogen; heavy metals: lead (Pb), copper (Cu), chromium (Cr), cadmium (Cd). Concentrations of heavy metals in snow-dust were detected thousands of times higher than those in the snowmelt water. In this study, analysis of heavy metal concentration was conducted considering different distances and the wind direction within the impact zone of the oil refinery. The sequence of heavy metals according to their mean concentrations in the snow-dust samples was the following: Pb > Cr > Cu > Cd. Heavy metals highly correlated among each other. The load of snow-dust was evaluated to determine the pollution level in the study area. The highest daily load of snow-dust was 45.81 +/- 12.35 mg/m2 in the north-western direction from the oil refinery. According to classification of the daily load of snow-dust a lower than medium-risk level of pollution was determined in the vicinity of the oil refinery.

    This digital geologic map of the Nevada Test Site (NTS) and vicinity, as well as its accompanying digital geophysical maps, are compiled at 1:100,000 scale. The map compilation presents new polygon (geologic map unit contacts), line (fault, fold axis, metamorphic isograd, dike, and caldera wall) and point (structural attitude) vector data for the NTS and vicinity, Nye, Lincoln, and Clark Counties, Nevada, and Inyo County, California. The map area covers two 30 x 60-minute quadrangles-the Pahute Mesa quadrangle to the north and the Beatty quadrangle to the south-plus a strip of 7.5-minute quadrangles on the east side-72 quadrangles in all. In addition to the NTS, the map area includes the rest of the southwest Nevada volcanic field, part of the Walker Lane, most of the Amargosa Desert, part of the Funeral and Grapevine Mountains, some of Death Valley, and the northern Spring Mountains. This geologic map improves on previous geologic mapping of the same area (Wahl and others, 1997) by providing new and updated Quaternary and bedrock geology, new geophysical interpretations of faults beneath the basins, and improved GIS coverages. Concurrent publications to this one include a new isostatic gravity map (Ponce and others, 1999) and a new aeromagnetic map (Ponce, 1999).

    Exponential industrialization and rapid urbanization have resulted in contamination of soil by metals from anthropogenic sources in Dongguan, China. The aims of this research were to determine the concentration and distribution of various metals (arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu), mercury (Hg), nickel (Ni), lead (Pb) and zinc (Zn)) in soils and identify their potential health risks for local residents. A total of 106 soil samples were collected from the vicinity of industrial sites in Dongguan. Two types of samples were collected from each site: topsoil (0-20 cm, TS) and shallow soil (20-50 cm, SS). Results showed that the soils were contaminated by metals and pollution was mainly focused on TS. The geoaccumulation index (Igeo) and pollution indexes (PI) implied that there was a slight increase in the concentrations of Cd, Cu, Hg, Ni, and Pb, but the metal pollution caused by industrial activities was less severe, and elements of As and Cr exhibited non-pollution level. The risk assessment results suggested that there was a potential health risk associated with As and Cr exposure for residents because the carcinogenic risks of As and Cr via corresponding exposure pathways exceeded the safety limit of 10(-6) (the acceptable level of carcinogenic risk for humans). Furthermore, oral ingestion and inhalation of soil particles are the main exposure pathways for As and Cr to enter the human body. This study may provide basic information of metal pollution control and human health protection in the vicinity of industrial regions.

    Full Text Available Marketing system of fresh fruits and vegetable in the context of the rapidly growing dynamic markets in Jakarta and the vicinity was studied. Unstructured interviews and observations of key persons, and panels were conducted, primarily in three main wholesale markets in Jakarta and the vicinity and some supermarkets. It was found that the availability of management services and associated facilities are not yet fully compatible with modern markets. Their role, therefore, in catering to the supermarkets is limited, in particular for vegetables due to requirements on quality and delivery schedules. In general, supermarkets procure their supply directly from production centers through special/dedicated suppliers, which currently amounts to about 1% to 5% of total production from production centers. If policy and conducive economic incentive are available, wholesale markets are not only domain of public investment anymore, but also private investments alike. The newly established wholesale markets show that they now have a higher rate of utilization than in the years before. It is therefore for the local government and the central government to furthers devise conducive policy and regulatory measures, and for the private to take this opportunity in terms of investment in developing the economy of the region.

    Rapid population growth since the 1930s in Ocean County and vicinity, New Jersey, has placed increasing demands upon the area’s freshwater resources. To examine effects of groundwater withdrawals, a three-dimensional groundwater-flow model was developed to simulate the groundwater-flow systems of five area aquifers: the unconfined Kirkwood-Cohansey aquifer system and Vincentown aquifer, and three confined aquifers— the Rio Grande water-bearing zone, the Atlantic City 800-foot sand, and the Piney Point aquifer. The influence of withdrawals is evaluated by using transient groundwater-flow model simulations that incorporate three withdrawal schemes. These are (1) no-withdrawal conditions; (2) 2000–03 withdrawal conditions, using reported monthly withdrawals at all production wells from January 2000 through December 2003; and (3) maximum-allocation withdrawal conditions using the maximum withdrawal allowed by New Jersey Department of Environmental Protection permits at each well. Particle tracking analysis, using results from model simulations, delineated particle flow paths from production wells to the point of recharge, and estimated particle travel times.Compared with no-withdrawal conditions, 2000–03 withdrawal conditions reduced the amount of groundwater flow out of the Kirkwood-Cohansey aquifer system into streams, increased the net flow of water into other layers, reduced net flow into or out of storage, and reduced flow from the Kirkwood-Cohansey aquifer system to constant head cells.Freshwater discharging to the Barnegat Bay-Little Egg Harbor estuary from streams and groundwater is essential to maintaining the ecology of the bay. Examination of selected stress periods indicates that simulated base flow in streams flowing into the Barnegat Bay-Little Egg Harbor estuary is reduced by as much as 49 cubic feet per second for 2000 to 2003 withdrawal conditions when compared with no-withdrawal conditions.In the three confined aquifers, water levels during

    IntroductionIn 2007, the California Ocean Protection Council initiated the California Seafloor Mapping Program (CSMP), designed to create a comprehensive seafloor map of high-resolution bathymetry, marine benthic habitats, and geology within the 3-nautical-mile limit of California’s State Waters. The CSMP approach is to create highly detailed seafloor maps through collection, integration, interpretation, and visualization of swath bathymetry data, acoustic backscatter, seafloor video, seafloor photography, high-resolution seismic-reflection profiles, and bottom-sediment sampling data. The map products display seafloor morphology and character, identify potential marine benthic habitats, and illustrate both the surficial seafloor geology and shallow subsurface geology.The Monterey Canyon and Vicinity map area lies within Monterey Bay in central California. Monterey Bay is one of the largest embayments along the west coast of the United States, spanning 36 km from its northern to southern tips (in Santa Cruz and Monterey, respectively) and 20 km along its central axis. Not only does it contain one of the broadest sections of continental shelf along California’s coast, it also contains Monterey Canyon, one of the largest and deepest submarine canyons in the world. Note that the California’s State Waters limit extends farther offshore between Santa Cruz and Monterey so that it encompasses all of Monterey Bay.The coastal area within the map area is lightly populated. The community of Moss Landing (population, 204) hosts the largest commercial fishing fleet in Monterey Bay in its harbor. The map area also includes parts of the cities of Marina (population, about 20,000) and Castroville (population, about 6,500). Fertile lowlands of the Salinas River and Pajaro River valleys largely occupy the inland part of the map area, and land use is primarily agricultural.The offshore part of the map area lies completely within the Monterey Bay National Marine Sanctuary.

    A pollution gradient was observed in tree foliage sampled in the vicinity of a large aluminium production facility in Patagonia (Argentina). Leaves of Eucalyptus rostrata, and Populus hybridus and different needle ages of Pinus spec. were collected and concentrations of aluminium (Al) and sulphur (S) as well as physiological parameters (chlorophyll and lipid oxidation products) were analyzed. Al and S concentrations indicate a steep pollution gradient in the study showing a relationship with the physiological parameters in particular membrane lipid oxidation products. The present study confirms that aluminium smelting results in high Al and sulphur deposition in the study area, and therefore further studies should be carried out taking into account potentially adverse effects of these compounds on human and ecosystem health.

    As a result of dense installations of public mobile base station, additional electromagnetic radiation occurs in the living environment. In order to determine the level of radio-frequency radiation generated by base stations, extensive electromagnetic field strength measurements were carried out for 664 base station locations. Base station locations were classified into three categories: indoor, masts and locations with installations on buildings. Having in mind the large percentage (47 %) of sites with antenna masts, a detailed analysis of this location category was performed, and the measurement results were presented. It was concluded that the total electric field strength in the vicinity of base station antenna masts in no case exceeded 10 V m(-1), which is quite below the International Commission on Non-Ionizing Radiation Protection reference levels. At horizontal distances >50 m from the mast bottom, the median and maximum values were <1 and 2 V m(-1), respectively.

    2017-01-01

    Full Text Available Multinucleon transfer in low-energy nucleus-nucleus collisions is widely discussed as a method of production of yet-unknown neutron-rich nuclei hardly accessible (or inaccessible by other methods. Modeling of complicated dynamics of nuclear reactions induced by heavy ions is done within a multidimensional dynamical model of nucleus-nucleus collisions based on the Langevin equations. The model gives a continuous description of the system evolution starting from the well-separated target and projectile in the entrance channel of the reaction up to the formation of final reaction products. In this paper, rather recent sets of experimental data for the 136Xe+198Pt,208Pb reactions are analyzed together with the production cross sections for neutron-rich nuclei in the vicinity of the N = 126 magic shell.

  16. Temperature Changes in the Vicinity of Thermally Loaded Structure Embedded in the Soil: Effect of Sand Content and Saturation Degree

    Różański, Adrian

    2017-06-01

    Due to the rapid development of geothermal technologies, the problem of efficient and proper evaluation of soil thermal conductivity becomes extremely important. Factors mostly affecting the soil conductivity are the conductivity of solid phase and the degree of saturation. The former one is mainly affected by the mineral composition, in particular, by the content of quartz whose conductivity is the highest one among all the minerals forming soil skeleton. Organic matter, because of its relatively low conductivity, influences the solid conductivity as well. The problem addressed in the paper is the influence of mentioned factors on temperature changes in the vicinity of thermally loaded structure embedded in the soil medium. Numerical simulations are carried out for different values of soil thermal conductivity resulting from various quartz contents and degrees of saturation. In addition, a weak coupled - heat and water transport - problem is considered.

    We investigate LiVS2 and LiVSe2 with a triangular lattice as itinerant analogues of LiVO2 known for the formation of a valence-bond solid (VBS) state out of an S=1 frustrated magnet. LiVS2, which is located at the border between a metal and a correlated insulator, shows a first order transition from a paramagnetic metal to a VBS insulator at Tc approximately 305 K upon cooling. The presence of a VBS state in the close vicinity of insulator-metal transition may suggest the importance of itinerancy in the formation of a VBS state. We argue that the high temperature metallic phase of LiVS2 has a pseudogap, likely originating from the VBS fluctuation. LiVSe2 was found to be a paramagnetic metal down to 2 K.

    2016-03-01

    Full Text Available A series of new fluorescent dye bearing monomers, including glycomonomers, based on maleamide and maleic esteramide was synthesized. The dye monomers were incorporated by radical copolymerization into thermo-responsive poly(N‑vinyl-caprolactam that displays a lower critical solution temperature (LCST in aqueous solution. The effects of the local molecular environment on the polymers’ luminescence, in particular on the fluorescence intensity and the extent of solvatochromism, were investigated below as well as above the phase transition. By attaching substituents of varying size and polarity in the close vicinity of the fluorophore, and by varying the spacer groups connecting the dyes to the polymer backbone, we explored the underlying structure–property relationships, in order to establish rules for successful sensor designs, e.g., for molecular thermometers. Most importantly, spacer groups of sufficient length separating the fluorophore from the polymer backbone proved to be crucial for obtaining pronounced temperature regulated fluorescence responses.

    To determine the level of radiofrequency radiation generated by base stations of Global System for Mobile Communications and Universal Mobile Telecommunication System, extensive electromagnetic field strength measurements were carried out in the vicinity of 664 base station locations. These were classified into three categories: indoor, masts, and locations with installations on buildings. Although microcell base stations with antennas installed indoors typically emit less power than outdoor macrocell base stations, the fact that people can be found close to antennas requires exposure originating from these base stations to be carefully considered. Measurement results showed that maximum recorded value of electric field strength exceeded International Commission on Non-Ionizing Radiation Protection reference levels at 7% of indoor base station locations. At the same time, this percentage was much lower in the case of masts and installations on buildings (0% and 2.5%, respectively). © 2015 Wiley Periodicals, Inc.

    Geologic mapping, the collection of borehole geophysical logs and images, and passive diffusion bag sampling were conducted by the U.S. Geological Survey North Carolina Water Science Center in the vicinity of the GMH Electronics Superfund site near Roxboro, North Carolina, during March through October 2011. The study purpose was to assist the U.S. Environmental Protection Agency in the development of a conceptual groundwater model for the assessment of current contaminant distribution and future migration of contaminants. Data compilation efforts included geologic mapping of more than 250 features, including rock type and secondary joints, delineation of more than 1,300 subsurface features (primarily fracture orientations) in 15 open borehole wells, and the collection of passive diffusion-bag samples from 42 fracture zones at various depths in the 15 wells.

    This paper examines the viability of using Canoparmelia texana lichen species as a bioindicator of air pollution by radionuclides and rare earth elements (REEs) in the vicinity of a tin and lead industry. The lichen and soil samples were analyzed for uranium, thorium and REEs by instrumental neutron activation analysis. The radionuclides {sup 226}Ra, {sup 228}Ra and {sup 210}Pb were determined either by Gamma-ray spectrometry (GRS) (soils) or by radiochemical separation followed by gross alpha and beta counting using a gas flow proportional counter (lichens). The lichens samples concentrate radionuclides (on the average 25-fold higher than the background for this species) and REEs (on the average 10-fold higher), therefore they can be used as a fingerprint of contamination by the operation of the tin industry.

    One dimensional electron gas (1DEG) arrays in vicinal GaN/AlGaN heterostructures have been studied. The steps at the interface would lead to the lateral barriers and limit the electron movement perpendicular to such steps. Through a self-consistent Schrödinger-Poisson approach, the electron energy levels and wave functions were calculated. It was found that when the total electron density was increased, the lateral barriers were lowered due to the screening effects by the electrons, and the electron gas became more two-dimension like. The calculated 1DEG densities were compared to the experimental values and good agreements were found. Moreover, we found that a higher doping density is more beneficial to form 1-D like electron gas arrays.

    Gridded multibeam bathymetry covers approximately 10.4 square kilometers of sea floor in the vicinity of Cross Rip Channel in Nantucket Sound, offshore southeastern Massachusetts. Although originally collected for charting purposes during National Oceanic and Atmospheric Administration hydrographic survey H12007, these acoustic data, and the sea-floor sediment sampling and bottom photography stations subsequently occupied to verify them, show the composition and terrain of the seabed and provide information on sediment transport and benthic habitat. This report is part of an expanding series of cooperative studies by the U.S. Geological Survey, National Oceanic and Atmospheric Administration, and Massachusetts Office of Coastal Zone Management that provide a fundamental framework for research and resource-management activities (for example, windfarms, pipelines, and dredging) along the inner continental shelf offshore of Massachusetts.

    We report a direct observation of magnetic domain evolution near the Verwey transition (TV) in Fe3O4 films. We found the stripe domains in the Fe3O4/Mg2TiO4 film while the irregular domains in the Fe3O4/MgO film and the similar characters of magnetic domains in the vicinity of TV for both samples: the bigger domain size and the higher contrast of the phase signal below TV and the more disordered domain images at TV. Remarkably, the magnetic behaviors can be well understood and the domain-wall energy and the demagnetizing energy can be calculated from the magnetic domains near TV in the Fe3O4/Mg2TiO4 film. Our work presents a demonstration of the low-temperature magnetic domains and gives a new perspective to understand the Verwey transition in Fe3O4 thin films.

    During the period April 21-23, 1953, a pumping test was made on several irrigation wells penetrating alluvium about a mile southwest of Orovada, Nev., in order to determine the hydraulic characteristics of the aquifers commonly penetrated by wells in that vicinity. The test was made by the writer, engineer, and J.L Poole, geologist, United States Geological Survey, as part of an investigation of the ground-water resources of Nevada being by the U.S Geological Survey in cooperation with the State Engineer. Much recent interest in the development of underground water by pumping in the Orovada area made it desirable to make the pumping test in order to obtain data that might be helpful in the proper planning of future development.

    Chimneys convey exhaust gas produced in domestic heat appliances to the external environment and to do this they have to pass through elements such as roofs and floors. If these elements are made up of flammable materials the fire hazard may occur. In some European countries the number of roof fire is very high and they affect also certified chimneys, that is, tested following the prescription of the related standards. The aim of this paper is to highlight that the certification procedure does not allow to test chimneys in the worst condition, therefore, chimney installed following the manufacturer prescriptions may in some cases cause the overheating and subsequent roof fire. To do this, experimental tests have been performed for measuring the temperature on roofs in the vicinity of a certified chimney. The results show that the certification procedure should be revised.

    Aguirre-Valderrama, Alonso; Dobado, José A

    2008-12-01

    Here, we present a free web-accessible application, developed in the JAVA programming language for the calculation of vicinal coupling constant (3J(H,H)) of organic molecules with the H-Csp3-Csp3-H fragment. This JAVA applet is oriented to assist chemists in structural and conformational analyses, allowing the user to calculate the averaged 3J(H,H) values among conformers, according to its Boltzmann populations. Thus, the CAL3JHH program uses the Haasnoot-Leeuw-Altona equation, and, by reading the molecule geometry from a protein data bank (PDB) file format or from multiple pdb files, automatically detects all the coupled hydrogens, evaluating the data needed for this equation. Moreover, a "Graphical viewer" menu allows the display of the results on the 3D molecule structure, as well as the plotting of the Newman projection for the couplings.

    Recent radiochemical evidence from groundwater characterization and monitoring wells in the vicinity of the TYBO and BENHAM underground nuclear tests in Area 20 of the Nevada Test Site, suggests that migration of radionuclides within groundwater beneath this portion of Area 20 may be more rapid than previously thought. In order to gain a better understanding of the hydrogeologic conditions in the TYBO-BENHAM area for more accurate flow and transport modeling, a reevaluation of the subsurface geologic environment in the vicinity of the two underground tests was conducted. Eight existing drill holes provided subsurface control for the area. These holes included groundwater characterization and monitoring wells, exploratory holes, and large-diameter emplacement holes used for underground nuclear weapons tests. Detailed and consistent geologic descriptions of these holes were produced by updating existing geologic descriptions with data from petrographic, chemical, and mineralogic analyses, and current stratigraphic concepts of the region. The updated descriptions, along with surface geologic data, were used to develop a detailed geologic model of the TYBO-BENHAM area. This model is represented by diagrams that correlate stratigraphic, lithologic, and alteration intervals between holes, and by isopach and structure maps and geologic cross sections. Regional data outside the TYBO-BENHAM area were included in the isopach and structure maps to better evaluate the geology of the TYBO-BENHAM area in a regional context. The geologic model was then evaluated with regard to groundwater flow and radionuclide migration to assess the model's implications for flow and transport modeling. Implications include: (1) confirmation of the general hydrogeology of the area described in previous studies; (2) the presence of two previously unrecognized buried faults that could act as zones of enhanced permeability within aquifers; and (3) secondary alteration within tuff confining

    Most of the patients in the Intensive Care Unit for Children are new-borns and infants having an infection of the central nervous system, with systemic septic and respiratory infections. Therefore, mobile X-ray equipment is routinely used for diagnosis of the respiratory tract, heart and endovascular catheterization. The aim of this work was to determine the radiation exposure to children in the vicinity of the exposed patient in the same or next room. The mobile X-ray unit is a Phillips Practix 100 model, including mobile shields (made by the firm Weimer Strahlenschutz) for radiation protection of patients and personal. For dose measurements, a thermoluminescent dosimetry system with TLD-700 detectors (manufactured by Harshaw) and a microprocessor controlled TOLEDO 654 reader were used. Three measurement runs were carried out. In the first one, the dosimeters were placed on the bed, without the patient, and the x-ray unit was operated as for thoracic x-ray. The results show the adequate homogeneity of the irradiation field. In the second measurement run, dosimeters were placed on the neighbouring bed behind the shield as well as on the glass wall of the room at various heights and distances from the X-ray tube. The results show that doses are very low, practically in the range of the lowest detectable dose, about 5 {mu}Sv. In the 3rd measurement run, the configuration of dosimeters in the surroundings were the same, but the irradiation was carried out with a 2 year old female patient and the distribution of the patient's surface dose was measured. The entrance dose on the breast was found to be 0.17 mSv. The results of this study show that the exposure of children to radiation in the vicinity of the exposed patient in the same or next room is not measurable. Therefore there is no basis for the risk estimation of genetic, leukemogenic and cancerogenic detriment. (author)

  11. An atomistic mechanism study of GaN step-flow growth in vicinal m-plane orientations.

    Elucidation of homoepitaxial growth mechanisms on vicinal non-polar surfaces of GaN is highly important for gaining an understanding of and control thin film surface morphology and properties. Using first-principles calculations, we study the step-flow growth in m-plane GaN based on atomic row nucleation and kink propagation kinetics. Ga-N dimer adsorption onto the m-plane is energetically more favorable than that of Ga and N isolated adatoms. Therefore, we have treated the dimers as the dominant growth species attached to the step edges. By calculating the free energies of sequentially attached Ga-N dimers, we have elucidated that the a-step edge kink growth proceeds by parallel attachment rather than by across the step edge approach. We found a series of favorable configurations of kink propagation and calculated the free energy and nucleation barriers for kink evolution on five types of step edges (a, +c, -c, +a + c, and -a - c). By changing the chemical potential μ Ga and the excess chemical potential Δμ, the growth velocities at the five types of edges are controlled by the corresponding kink pair nucleation barrier E* in their free energy profiles. To explore the kink-flow growth instability observed at different Ga/N flux ratios, calculations of kink pairs on the incompact -c and +c-step edges are further performed to study their formation energies. Variations of these step edge morphologies with a tuned chemical environment are consistent with previous experimental observations, including stable diagonal ±a ± c-direction steps. Our work provides a first-principles approach to explore step growth and surface morphology of the vicinal m-plane GaN, which is applicable to analyze and control the step-flow growth of other binary thin films.

  12. Chemical evolution of 244Pu in the solar vicinity and its implications for the properties of r-process production

    Meteoritic abundances of r-process elements are analyzed to deduce the history of chemical enrichment by the r-process, from the beginning of disk formation to the present time in the solar vicinity. Our analysis combines the abundance information from short-lived radioactive nuclei such as 244Pu with the abundance information from stable r-process nuclei such as Eu. These two types of nuclei can be associated with one r-process event and an accumulation of events until the formation of the solar system, respectively. With the help of the observed local star formation (SF) history, we deduce the chemical evolution of 244Pu and obtain three main results: (I) the last r-process event occurred 130-140 Myr before the formation of the solar system; (II) the present-day low 244Pu abundance as measured in deep-sea reservoirs results from the low recent SF rate compared to ˜4.5-5 Gyr ago; and (III) there were ˜15 r-process events in the solar vicinity from the formation of the Galaxy to the time of solar system’s formation and ˜30 r-process events to the present time. Then, adopting the hypothesis that a neutron star (NS) merger is the r-process production site, we find that the ejected r-process elements are extensively spread out and mixed with interstellar matter, with a mass of ˜ 3.5× {10}6 M⊙, which is about 100 times larger than that for supernova ejecta. In addition, the event frequency of r-process production is estimated to be 1 per ~1400 core-collapse supernovae, which is identical to the frequency of NS mergers estimated from the analysis of stellar abundances.

    2008-03-10

    Within the scope of the present work, two main goals have been achieved: Firstly, the coincident Doppler broadening spectrometer (CDBS) at the high intense positron source NEPOMUC has been elaborately improved in order to increase the spatial resolution for defect mapping measurements and to investigate samples with shallow positron trapping sites which are present e. g. in magnesium. Secondly, as an application, the chemical vicinity of defects in the industrially used magnesium based alloy AZ31 has been examined by means of the detailed investigation of ion-irradiated specimen with positron annihilation spectroscopy. Detailed simulations with the finite-element simulation tool COMSOL were used to optimize the focal diameter of the positron beam at the sample position in order to increase the spatial resolution. With a value of 0.3 mm, sub-mm resolution has now been reached. The CDBS has been furthermore equipped with a sample cooling unit in order to reach liquid nitrogen temperature, maintaining the feature of scanning the sample for defect mapping. Defects and their chemical surrounding in ion irradiated magnesium and the magnesium based alloy AZ31 were then investigated on an atomic scale with the CDBS. In the respective spectra the chemical information and the defect contribution have been thoroughly separated. For this purpose, samples of annealed Mg were irradiated with Mg-ions in order to create exclusively defects. In addition Al- and Zn-ion irradiations on Mg-samples were performed in order to create samples with both defects and impurity atoms. The ion irradiated area on the samples was investigated with laterally and depth resolved positron Doppler broadening spectroscopy (DBS) and compared with SRIM-simulations of the vacancy distribution. The investigation of the chemical vicinity of crystal defects in AZ31 was performed with CDBS on Mg-ion irradiated AZ31 with Mg-ion irradiated Mg.

    Submarine volcanic vents are being used as natural laboratories to assess the effects of increased ocean acidity and carbon dioxide (CO2) concentration on marine organisms and communities. However, in the vicinity of volcanic vents other factors in addition to CO2, which is the main gaseous component of the emissions, may directly or indirectly confound the biota responses to high CO2. Here we used for the first time the expression of antioxidant and stress-related genes of the seagrass Posidonia oceanica to assess the stress levels of the species. Our hypothesis is that unknown factors are causing metabolic stress that may confound the putative effects attributed to CO2 enrichment only. We analyzed the expression of 35 antioxidant and stress-related genes of P. oceanica in the vicinity of submerged volcanic vents located in the islands of Ischia and Panarea, Italy, and compared them with those from control sites away from the influence of vents. Reverse-transcription quantitative polymerase chain reaction (RT-qPCR) was used to characterize gene expression patterns. Fifty-one percent of genes analyzed showed significant expression changes. Metal detoxification genes were mostly down-regulated in relation to controls at both Ischia and Panarea, indicating that P. oceanica does not increase the synthesis of heavy metal detoxification proteins in response to the environmental conditions present at the two vents. The up-regulation of genes involved in the free radical detoxification response (e.g., CAPX, SODCP and GR) indicates that, in contrast with Ischia, P. oceanica at the Panarea site faces stressors that result in the production of reactive oxygen species, triggering antioxidant responses. In addition, heat shock proteins were also activated at Panarea and not at Ischia. These proteins are activated to adjust stress-accumulated misfolded proteins and prevent their aggregation as a response to some stressors, not necessarily high temperature. This is the first

    Full Text Available Abstract Background A previous study revealed an environmental contamination by heavy metals in the vicinity of two non-ferrous metal plants in Ath, Belgium. The purpose of the current cross-sectional study was to estimate exposure of the population to heavy metals in the vicinity of the plants, in comparison with population living further away. Methods We did a random sampling in the general population of Ath in two areas: a central area, including the plants, and a peripheral area, presumably less exposed. We quantified cadmium, lead, nickel, chromium and cobalt in blood and/or urine of children and adults in three age groups: (i children aged 2.5 to 6 years (n = 98, (ii children aged 7 to 11 years (n = 74, and (iii adults aged 40 to 60 years (n = 106. We also studied subclinical health effects by quantifying retinol-binding protein and microalbuminuria, and by means of a Strengths and Difficulties Questionnaire. Results We obtained a participation rate of 24 %. Blood lead levels were significantly higher in young children living in the central area (18.2 μg/l ; 95 % CI: 15.9–20.9 compared to the peripheral area (14.8 μg/l ; 95 % CI: 12.6–17.4. We observed no other significant mean difference in metal concentrations between the two areas. In the whole population, blood lead levels were higher in men (31.7 μg/l ; 95 % CI: 27.9–36.1 than in women (21.4 μg/l ; 95 % CI: 18.1–25.3. Urine cadmium levels were 0.06 μg/g creatinine (95 % CI: 0.05–0.07, 0.21 μg/g creatinine (95 % CI: 0.17–0.27, and 0.25 μg/g creatinine (95 % CI: 0.20–0.30 for children, men, and women, respectively. Conclusions Despite higher blood lead levels in young children living close to the plants, observed metal concentrations remain in the range found in other similar biomonitoring studies in the general population and are below the levels of concern for public health.

    The Nez Perce Tribe Department of Fisheries Resource Management, Watershed Division approaches watershed restoration with a ridge-top to ridge-top approach. Watershed restoration projects within the Lolo Creek watershed are coordinated with the Clearwater National Forest and Potlatch Corporation. The Nez Perce Tribe began watershed restoration projects within the Lolo Creek watershed of the Clearwater River in 1996. Fencing to exclude cattle for stream banks, stream bank stabilization, decommissioning roads, and upgrading culverts are the primary focuses of this effort. The successful completion of the replacement and removal of several passage blocking culverts represent a major improvement to the watershed. These projects, coupled with other recently completed projects and those anticipated in the future, are a significant step in improving habitat conditions in Lolo Creek.

    2015-01-01

    Full Text Available To estimate the tritium doses of the residents living in the vicinity of a nuclear power plant, urine samples of 34 adults were collected from residents living near the Qinshan nuclear power plant. The tritium-in-urine (HTO plus OBT was measured by liquid scintillation counting. The doses of tritium-in-urine from participants living at 2, 10 and 22 km were in a range of 1.26–6.73 Bq/L, 1.31–3.09 Bq/L and 2.21–3.81 Bq/L, respectively, while the average activity concentrations of participants from the three groups were 3.53 ± 1.62, 2.09 ± 0.62 and 2.97 ± 0.78 Bq/L, respectively. The personal committed effective doses for males were 2.5 ± 1.7 nSv and for females they were 2.9 ± 1.3 nSv. These results indicate that tritium concentrations in urine samples from residents living at 2 km from a nuclear power plant are significantly higher than those at 10 km. It may be the downwind direction that caused a higher dose in participants living at 22 km. All the measured doses of tritium-in-urine are in a background level range.

    This report presents information used to characterize the groundwater-flow system in the Puyallup River Watershed and vicinity, and includes descriptions of the geology and hydrogeologic framework; groundwater recharge and discharge; groundwater levels and flow directions; seasonal groundwater level fluctuations; interactions between aquifers and the surface-water system; and a water budget. The study area covers about 1,220 square miles in northern Pierce and southern King Counties, Washington; extends north to the Green River and Auburn Valley and southwest to the Puyallup River and adjacent uplands; and is bounded on the south and east by foothills of the Cascade Range and on the west by Puget Sound. The area is underlain by a northwest-thickening sequence of unconsolidated glacial and interglacial deposits, which overlie sedimentary and volcanic bedrock units that crop out in the foothills along the southern and eastern margin of the study area. Geologic units were grouped into 13 hydrogeologic units consisting of aquifers, confining units, and an underlying bedrock unit. A surficial hydrogeologic unit map was developed and used with well information from 1,012 drillers’ logs to construct 8 hydrogeologic sections, and unit extent and thickness maps.

  6. Geology, hydrology, and water quality of the glacial drift aquifer in the vicinity of the Nelson landfill near Yorkville, Illinois

    2006-01-01

    The geologic and hydrologic characteristics of the sand-and-gravel deposits that compose the glacial drift aquifer in the vicinity of the Nelson Landfill site in Yor-kville, Illinois indicate that the aquifer could be devel-oped as a source of public water supply. The geology of these deposits within the Newark Bedrock Valley is com-plex, however, and a detailed investigation of their water bearing and transmitting properties will be required to successfully locate high-capacity wells. Volatile organic compounds, pesticides, and cyanide were not detected in ground water during this investiga-tion. Metals and nitrogen compounds were not detected at concentrations above their Maximum Contaminant Level. Iron, manganese, and aluminum were detected at concentrations above their Secondary Maximum Con-taminant Level and various constituents were detected at concentrations above background levels downgradi-ent of the landfill. Nitrate and ammonia, presumably derived from agricultural practices, also were detected in samples from locations hydraulically upgradient of the landfill. Oxidation-reduction conditions in the aquifer become more reducing with depth. This change is reflected by a change in the type of nitrogen compound detected and the concentration of dissolved oxygen and iron in the glacial drift aquifer. Concentrations of some of the major ions and metals may be affected by disso-lution of carbonate minerals in the aquifer and perhaps road salts.

    This work presents an experimental and modeling study of the electromagnetic environment in the vicinity of a high voltage substation located in eastern Algeria (Annaba city) specified with a very high population density. The effects of electromagnetic fields emanating from the coupled multi-lines high voltage power systems (MLHV) on the health of the workers and people living in proximity of substations has been analyzed. Experimental Measurements for the Multi-lines power system proposed have been conducted in the free space under the high voltage lines. Field's intensities were measured using a referenced and calibrated electromagnetic field meter PMM8053B for the levels 0 m, 1 m, 1.5 m and 1.8 m witch present the sensitive's parts as organs and major functions (head, heart, pelvis and feet) of the human body. The measurement results were validated by numerical simulation using the finite element method and these results are compared with the limit values of the international standards. We project to set own national standards for exposure to electromagnetic fields, in order to achieve a regional database that will be at the disposal of partners concerned to ensure safety of people and mainly workers inside high voltage electrical substations.

    Full Text Available A study of the environmental impacts on the coral resources in the vicinity of the Saint Martin Island Bangladesh was conducted with a view to making an assessment of the current status of coral resources in the island and identifying major natural and anthropogenic environmental threats to the future sustainability of these resources. It is evident that the coral resources have been reduced significantly and currently only 41 coral species are available. The existing environmental condition assessed by pH salinity turbidity and temperature in the island is not found responsible for the survival of the corals. The study also reveals that the major anthropogenic interventions are responsible for the gradual depletion of the coral resources. The major anthropogenic threats to the coral resources are coral collection and overfishing. In addition coral extraction is identified as a potential threat to the future integrity of coral communities in the island. Environmental threats from anthropogenic activities related to sedimentation land erosion and pollution are also the concerns for the coral communities in the island. For the conservation of the coral population no coral monitoring cell has been established in this island.

    Examinations of various features of gunshot residue (GSR) collected from targets in a function of the shooting distance as well as from hands and the forearm, front and back parts of the upper clothing of the shooting person were performed with SEM-EDX. GSR samples were obtained using Walther P-99 pistol and Luger 9 mm ammunition of Polish production. The experiments were designed in such a manner that the substrates for collecting GSR reminded the ones usually obtained for examinations within criminal cases. Results of the performed examinations in the form of parameters describing GSR particles: the number of GSR, proportions of their chemical classes as well as their sizes revealed a dependence on the shooting distance both, in the direction of shooting and backwards, i.e. on the shooting person. The analysis of the distribution of particles in the vicinity of the shooting gun may be utilised in description of the general rules of the dispersion of GSR as well as in the reconstruction of a real shooting case.

    To clarify the time evolution of water origins in the vicinity of a tropical cyclone (TC)'s center, we have simulated Typhoon Man-yi (July 2007) in our case study, using an isotopic regional spectral model. The model results confirm that the replacement of water origins occurs successively as the TC develops and migrates northward over the western North Pacific. It is confirmed that, in this case, a significant proportion of total precipitable water around the cyclone center comes from external regions rather than the underlying ocean during the mature stage of a TC. Similar features can also be seen in the proportion of each oceanic origin to total condensation. Indian Ocean, South China Sea, and Maritime Continent water vapors begin to increase gradually at the developing stage and reach their peak at the decay stage when the TC approaches southwestern Japan. These remote ocean vapors are transported to the east of the cyclone via the moisture conveyor belt, a zone characterized by distinct low-level moisture flux that stretches from the Indian Ocean to the TC, and are further supplied into the inner region of the TC by inflow within the boundary layer associated with its secondary circulation. Since it takes time to undergo these two dynamic processes, the delayed influence of remote ocean vapors on the TC appears to become evident during the mature stage.

    The small-scale structure of the interstellar magnetic field in the vicinity of the Herbig-Haro objects HH 7-11/HH 12 and HH 33/40 is derived from CCD imaging polarimetry of stars nearby to these young stellar object driven outflows. The outflow associated with SVS 13/HH 7-11 lies approximately parallel to the local field direction. The outflow mapped by HH 33/HH 40 is also well aligned with the local magnetic field. However, the orientation of the outflow associated with HH 12 located 2 arcmin to the north of HH 7-11 is offset from the inferred magnetic field direction by 60 deg. These results taken together with those of previous studies suggest: (1) magnetic fields are directly or indirectly responsible for the observed orientation of outflows associated with newborn stars in the majority of cases; and (2) in some cases, the flow properties may depend upon other characteristics of the parent cloud core.

    We have systematically studied the evolution of magnetic properties, especially the coercivity and the remanence ratio in the vicinity of the Verwey transition temperature (TV), of high-quality epitaxial Fe3O4 thin films grown on MgO (001), MgAl2O4 (MAO) (001), and SrTiO3 (STO) (001) substrates. We observed rapid change of magnetization, coercivity, and remanence ratio at TV, which are consistent with the behaviors of resistivity versus temperature [ρ (T )] curves for the different thin films. In particular, we found quite different magnetic behaviors for the thin films on MgO from those on MAO and STO, in which the domain size and the strain state play very important roles. The coercivity is mainly determined by the domain size but the demagnetization process is mainly dependent on the strain state. Furthermore, we observed a reversal of remanence ratio at TV with thickness for the thin films grown on MgO: from a rapid enhancement for 40-nm- to a sharp drop for 200-nm-thick film, and the critical thickness is about 80 nm. Finally, we found an obvious hysteretic loop of coercivity (or remanence ratio) with temperature around TV, corresponding to the hysteretic loop of the ρ (T ) curve, in Fe3O4 thin film grown on MgO.

    Full Text Available The study was conducted to evaluate soil quality and impact of brick kiln on different physicochemical parameters of soils of agricultural field, located in the vicinity of Bhaktapur, Nepal. The study was carried out by determining the physicochemical characteristics of soil, soil fertility, and heavy metal contamination of soil. During the entire study period, water absorptivity of soil ranged from 2.4 to 3.3 mg/L, pH varies from 5.885 to 7.64, and organic carbon content and organic matter varied from 0.277 to 0.93%, from 0.477% to 1.603%, respectively. Nutrient content, that is, sulfate and nitrate concentration, in the soil ranged from 0.829 to 3.764 mol/L and from 0.984 to 29.99 mol/L, respectively. The findings revealed that concentrations of heavy metals (chromium and lead were within permissible limit, although the levels were higher in soil at 50 m and decrease farther from brick kiln. However, the physical parameters and nutrient content were deficient in soil at 50 m while increasing gradually at distances of 100 m and 150 m. The variation of result obtained for physical parameters supports the fact that quality of soil in terms of heavy metal content and nutrient content was directly proportional to the distance from the kiln; that is, the quality of soil increased with increasing distance.

  14. Stimulated bacterioplankton growth and selection for certain bacterial taxa in the vicinity of the ctenophore Mnemiopsis leidyi

    Full Text Available Episodic blooms of voracious gelatinous zooplankton, such as the ctenophore Mnemiopsis leidyi, affect pools of inorganic nutrients and dissolved organic carbon by intensive grazing activities and mucus release. This will potentially influence bacterioplankton activity and community composition, at least at local scales; however, available studies on this are scarce. In the present study we examined effects of M. leidyi on bacterioplankton growth and composition in incubation experiments. Moreover, we examined community composition of bacteria associated with the surface and gut of M. leidyi. High release of ammonium and high bacterial growth was observed in the treatments with M. leidyi relative to controls. Deep 454 pyrosequencing of 16S rRNA genes showed specific bacterial communities in treatments with M. leidyi as well as specific communities associated with M. leidyi tissue and gut. In particular, members of Flavobacteriaceae were associated with M. leidyi. Our study shows that M. leidyi influences bacterioplankton activity and community composition in the vicinity of the jellyfish. In particular during temporary aggregations of jellyfish, these local zones of high bacterial growth may contribute significantly to the spatial heterogeneity of bacterioplankton activity and community composition in the sea.

    As a result of dense deployment of public mobile base stations, additional electromagnetic (EM) radiation occurs in the modern human environment. At the same time, public concern about the exposure to EM radiation emitted by such sources has increased. In order to determine the level of radio frequency radiation generated by base stations, extensive EM field strength measurements were carried out for 664 base station locations, from which 276 locations refer to the case of base stations with antenna system installed on buildings. Having in mind the large percentage (42 %) of locations with installations on buildings, as well as the inevitable presence of people in their vicinity, a detailed analysis of this location category was performed. Measurement results showed that the maximum recorded value of total electric field strength has exceeded International Commission on Non-Ionizing Radiation Protection general public exposure reference levels at 2.5 % of locations and Serbian national reference levels at 15.6 % of locations. It should be emphasised that the values exceeding the reference levels were observed only outdoor, while in indoor total electric field strength in no case exceeded the defined reference levels. © The Author 2015.

    Vicinal oxygen chelate proteins (VOC) are members of the metalloenzyme superfamily, which plays roles in many biological reactions. Some members of the VOC superfamily have been systematically characterized but not in Brassica napus. In this study, 38 VOC genes were identified based on their conserved domains. The present results revealed that most of the BnaVOC genes have few introns, and all contained the typical VOC structure of βαβββ modules. The BnaVOC genes are distributed unevenly across 15 chromosomes in B. napus and occur as gene clusters on chromosomes C5 and A6. The synteny and phylogenetic analyses revealed that the VOC gene family is a consequence of mesopolyploidy events that occurred in Brassica evolution, and whole-genome duplication and segmental duplication played a major role in the expansion of the BnaVOC gene family. The expression profile analysis indicated that the expression of most BnaVOCs was increased in the leaves and late stage seeds. Further results indicated that seeds of B. napus with a high oil content show higher expression levels under drought stress conditions, suggesting that BnaVOCs not only respond to abiotic stress but may also affect lipid metabolism in drought stress. This present study provides a comprehensive overview of the VOC gene family and provides new insights into their biological function in B. napus evolution. PMID:28536594

    The magnetocaloric effect in the vicinity of the martensitic transformation for a single crystalline alloy with a composition close to the stoichiometric Ni{sub 2}MnGa has been determined indirectly by M(T,H) magnetization measurements. It has an inverse character. The magnetocaloric parameters, i.e., the magnetic entropy change, refrigeration capacity and various hysteretic effects have been calculated from the M(T,H) dependences. Besides the martensitic transition a weak entirely separated intermartensitic transition was observed. These two successive magneto-structural transformations give contributions to the observed magnetocaloric effect. Unusual dependence of entropy change as a function of magnetic field has been explained as arising because of two different mechanisms. Additionally, to confirm that studied martensitic transformation is a first order phase transition electrical resistivity and thermoelectric power measurements have been performed. - Highlights: • Inverse magnetocaloric effect in Ni{sub 50.4}Mn{sub 24.9}Ga{sub 24.7} single crystal was measured. • The martensitic and separated intermartensitic transition were investigated. • Anisotropy of measured magnetocaloric effect was discussed.

    This work presents indoor radon measurements in 42 dwellings in the city of Megalopolis, Southern Greece, located in the vicinity of 2 lignite-fired power plants and examines the effect of season, floor level and age of the dwellings on indoor radon concentration. The radon measurements have been carried out using the LR-115, type II and CR-39 alpha track detectors in 'closed-can' geometry. The average annual indoor radon concentration (GM) was found to be 52 Bq m{sup -3}, which is well below the recommended action level of the European Union. This value corresponds to an annual effective dose to the population of 1.3 {+-} 0.4 mSv. Season and age of the examined dwellings represent factors that affected significantly the indoor radon in Megalopolis, while the effect of floor level appeared to be not significant. Radium activity concentration values, measured by gamma-ray spectrometry in 20 sub-samples of six soil cores (60-135 cm depth), collected from the surrounding area of the city, were found to be consistent with the Greek and world average values. Based on the results of this study, it is concluded that the effect of the lignite-fired power plants on indoor radon concentration in Megalopolis' dwellings was not significant.

    To estimate the tritium doses of the residents living in the vicinity of a nuclear power plant, urine samples of 34 adults were collected from residents living near the Qinshan nuclear power plant. The tritium-in-urine (HTO plus OBT) was measured by liquid scintillation counting. The doses of tritium-in-urine from participants living at 2, 10 and 22 km were in a range of 1.26-6.73 Bq/L, 1.31-3.09 Bq/L and 2.21-3.81 Bq/L, respectively, while the average activity concentrations of participants from the three groups were 3.53 ± 1.62, 2.09 ± 0.62 and 2.97 ± 0.78 Bq/L, respectively. The personal committed effective doses for males were 2.5 ± 1.7 nSv and for females they were 2.9 ± 1.3 nSv. These results indicate that tritium concentrations in urine samples from residents living at 2 km from a nuclear power plant are significantly higher than those at 10 km. It may be the downwind direction that caused a higher dose in participants living at 22 km. All the measured doses of tritium-in-urine are in a background level range.

    Full Text Available The results of the application of an unsupervised learning (neural network approach comprising a Self Organizing Map (SOM, to distinguish micro-earthquakes from quarry blasts in the vicinity of Istanbul, Turkey, are presented and discussed. The SOM is constructed as a neural classifier and complementary reliability estimator to distinguish seismic events, and was employed for varying map sizes. Input parameters consisting of frequency and time domain data (complexity, spectral ratio, S/P wave amplitude peak ratio and origin time of events extracted from the vertical components of digital seismograms were estimated as discriminants for 179 (1.8 < Md < 3.0 local events. The results show that complexity and amplitude peak ratio parameters of the observed velocity seismogram may suffice for a reliable discrimination, while origin time and spectral ratio were found to be fuzzy and misleading classifiers for this problem. The SOM discussed here achieved a discrimination reliability that could be employed routinely in observatory practice; however, about 6% of all events were classified as ambiguous cases. This approach was developed independently for this particular classification, but it could be applied to different earthquake regions.

    Trace metal contamination is a major environmental and health problem virtually in all countries. The present study was aimed to estimate the lead content of pot marigold (Calendula officinalis L.) inflorescences and leaves collected from a nonpolluted test field. The lead content in dry pot marigold inflorescences was 9.34 ± 0.79 µg/g, in dry leaves 11.57 ± 0.47 µg/g, and in soil 0.649 ± 0.012 µg/g. The distance of pot marigold collection beds (30-220 m from the motorway) had no effect on lead content. There was a strong positive correlation between the amount of precipitations and lead content of pot marigold leaves but not inflorescences indicating the soil as primarily the source of increased lead content. In conclusion, no effect of motorway vicinity was found for pot marigold inflorescences or leaves lead content; however, as a precaution, it is not recommended to collect the plants during or just after showers.

    Full Text Available The North Brazil Current Rings (NBCR penetration into the Caribbean Sea is being investigated by employing a merged altimeter-derived sea height anomaly (TOPEX/Poseidon, Jason-1 and ERS-1, 2, the ocean surface color data (SeaWiFS and Global Drifter Program information. Four strategies are being applied to process the data: (1 calculations of the Okubo-Weiss parameter for NBCR identification, (2 longitude-time plots (also known as Hovmöller diagrams, (3 two-dimensional Radon transforms and (4 two-dimensional Fourier transforms.

    A twofold NBCR structure has been detected in the region under investigation. The results have shown that NBC rings mainly propagate into the Caribbean Sea along two principal pathways (near 12° N and 17° N in the ring translation corridor. Thus, rings following the southern pathway in the fall-winter period can enter through very shallow southern straits as non-coherent structures. A different behavior is observed near the northern pathway (~17° N, where NBC rings are thought to have a coherent structure during their squeezing into the eastern Caribbean, i.e. conserving the principal characteristics of the incident rings. We attribute this difference in the rings' behavior to the vertical scales of the rings and to the bottom topography features in the vicinity of the Lesser Antilles.

    A finite-element model of the groundwater flow system in the vicinity of Yucca Mountain at the Nevada Test Site was developed using parameter estimation techniques. The model simulated steady-state ground-water flow occurring in tuffaceous, volcanic , and carbonate rocks, and alluvial aquifers. Hydraulic gradients in the modeled area range from 0.00001 for carbonate aquifers to 0.19 for barriers in tuffaceous rocks. Three model parameters were used in estimating transmissivity in six zones. Simulated hydraulic-head values range from about 1,200 m near Timber Mountain to about 300 m near Furnace Creek Ranch. Model residuals for simulated versus measured hydraulic heads range from -28.6 to 21.4 m; most are less than +/-7 m, indicating an acceptable representation of the hydrologic system by the model. Sensitivity analyses of the model 's flux boundary condition variables were performed to assess the effect of varying boundary fluxes on the calculation of estimated model transmissivities. Varying the flux variables representing discharge at Franklin Lake and Furnace Creek Ranch has greater effect than varying other flux variables. (Author 's abstract)

  5. The Sociocultural Value of Upland Regions in the Vicinity of Cities in Comparison With Urban Green Spaces

    2016-11-01

    Full Text Available Mountain and upland regions provide a wide range of ecosystem services to residents and visitors. While ecosystem research in mountain regions is on the rise, the linkages between sociocultural benefits and ecological systems remain little explored. Mountainous regions close to urban areas provide numerous benefits to a large number of individuals, suggesting a high social value, particularly for cultural ecosystem services. We explored and compared visitors' valuation of ecosystem services in the Pentland Hills, an upland range close to the city of Edinburgh, Scotland, and urban green spaces within Edinburgh. Based on 715 responses to user surveys in both study areas, we identified intense use and high social value for both areas. Several ecosystem services were perceived as equally important in both areas, including many cultural ecosystem services. Significant differences were revealed in the value of physically using nature, which Pentland Hills users rated more highly than those in the urban green spaces, and of mitigation of pollutants and carbon sequestration, for which the urban green spaces were valued more highly. Major differences were further identified for preferences in future land management, with nature-oriented management preferred by about 57% of the interviewees in the Pentland Hills, compared to 31% in the urban parks. The study highlights the substantial value of upland areas in close vicinity to a city for physically using and experiencing nature, with a strong acceptance of nature conservation.

    2016-10-01

    We studied the optical anisotropy of InGaAs quantum wire (QWR) arrays on vicinal (111)B GaAs. Polarized photoluminescence (PL) studies showed that the PL is polarized preferentially along [1-10], where the polarization degree ρ is about 9.4%. We also theoretically investigated the electronic states of the InGaAs QWR arrays to clarify how the optical anisotropy is affected by (1) the corrugated structure, (2) the strain effect including piezoelectricity, and (3) the thickness difference of the InGaAs layers on the two facets of the corrugated structure. While ρ for the corrugated structure is almost the same as that for a flat quantum well structure, the strain effects and the thickness difference result in the increases of ρ by about 1.9 and 2.5 times. The calculated results were compared to the experimental data. It was found that the effects of the strain and the thickness difference are important to explain the optical anisotropy of the InGaAs QWR arrays.

    This report describes earthquake activity within approximately 65 km of Yucca Mountain site during the October 1, 2004 to September 30, 2006 time period (FY05-06). The FY05-06 earthquake activity will be compared with the historical and more recent period of seismic activity in the Yucca Mountain region. The relationship between the distribution of seismicity and active faults, historical patterns of activity, and rates of earthquakes (number of events and their magnitudes) are important components in the assessment of the seismic hazard for the Yucca Mountain site. Since October 1992 the University of Nevada has compiled a catalog of earthquakes in the Yucca Mountain area. Seismicity reports have identified notable earthquake activity, provided interpretations of the seismotectonics of the region, and documented changes in the character of earthquake activity based on nearly 30 years of site-characterization monitoring. Data from stations in the seismic network in the vicinity of Yucca Mountain is collected and managed at the Nevada Seismological Laboratory (NSL) at the University of Nevada Reno (UNR). Earthquake events are systematically identified and cataloged under Implementing Procedures developed in compliance with the Nevada System of Higher Education (NSHE) Quality Assurance Program. The earthquake catalog for FY05-06 in the Yucca Mountain region submitted to the Yucca Mountain Technical Data Management System (TDMS) forms the basis of this report.

    The 1984 Windscale study raised concern about a possible association between living in the vicinity of nuclear power plants and childhood cancer. No such effect for all cancers was seen in ecological studies in Germany (1980-1995). Results from exploratory analyses led to a new study. Pre-selected areas around all 16 major nuclear power plants in Germany formed the study area. The design is a matched case-control study; cases are all cancers under five years diagnosed in 1980-2003: 1592 cases, and 4735 controls. Inverse distance of place of residence to the nearest nuclear power plant at the time of diagnosis was used as the independent variable in a conditional logistic regression model. Results show an increased risk for childhood cancer under five years when living near nuclear power plants in Germany. The inner 5-km zone shows an increased risk (odds ratio 1.47; lower one-sided 95% confidence limit 1.16). The effect was largely restricted to leukaemia. The results are compatible with the corresponding subgroups in the previous German ecological studies, with which this study shares most of the cases. They contrast with the lack of an effect observed or expected from other studies due to low doses from routine nuclear power plant operation.

  9. Differential Evolution Algorithm with Diversified Vicinity Operator for Optimal Routing and Clustering of Energy Efficient Wireless Sensor Networks.

    2015-01-01

    Due to large dimension of clusters and increasing size of sensor nodes, finding the optimal route and cluster for large wireless sensor networks (WSN) seems to be highly complex and cumbersome. This paper proposes a new method to determine a reasonably better solution of the clustering and routing problem with the highest concern of efficient energy consumption of the sensor nodes for extending network life time. The proposed method is based on the Differential Evolution (DE) algorithm with an improvised search operator called Diversified Vicinity Procedure (DVP), which models a trade-off between energy consumption of the cluster heads and delay in forwarding the data packets. The obtained route using the proposed method from all the gateways to the base station is comparatively lesser in overall distance with less number of data forwards. Extensive numerical experiments demonstrate the superiority of the proposed method in managing energy consumption of the WSN and the results are compared with the other algorithms reported in the literature.

    Molecular-dynamics simulations of water-benzene mixtures at 573 K and pressures in the 85-140 bars range have been performed to examine local structure and dynamics of the mixtures, which exhibit anomalously large volume expansion on mixing as recently found by in situ near-infrared measurements. Fractional charges for a simple-point-charge-type potential of water were adjusted so as to reproduce liquid densities and the gas-to-liquid transition pressure of neat water at 573 K. A Lennard-Jones-type potential for benzene was used and the Lorentz-Berthelot combination rule was applied to the water-benzene interaction. Simulations with a N-P-T ensemble of 800-molecule system have been performed and the results reproduce well the anomalous volumetric behavior of the mixtures with the mole fraction of benzene in the 0.3-0.8 range. Pair distribution functions, coordination numbers, and self-diffusion coefficients for the mixtures are calculated, and it is suggested that the local structure around water molecules undergoes drastic change by dissolution of benzene in the vicinity of the critical region, but that around benzene molecules seems to be understood as that of ordinary liquid mixtures.

    The Northwest Power Planning Council (NPPC) identified supplementation as a high priority to achieve its goal of increasing runs of anadromous fish in the Columbia Basin. Supplementation activities in the Lostine River and associated monitoring and evaluation conducted by the Nez Perce Tribe relate directly to the needs addressed in the Columbia River Basin Fish and Wildlife Program (NPPC 1994). Measure 7.4L.1 of the Program mandates that appropriate research accompany any proposed supplementation. In addition, measure 7.3B.2 of the Program stresses the need for evaluating supplementation projects to assess their ability to increase production. Finally, Section 7.4D.3 encourages the study of hatchery rearing and release strategies to improve survival and adaptation of cultured fish. In 1997, Oregon Department of Fisheries and Wildlife (ODFW) requested a modification of Permit 1011 to allow the take of adult spring chinook salmon. In 1998, the Nez Perce Tribe also requested a permit specific to activities on Lostine River. The permit was issued in 2000. A special condition in the permits required the development of a long term management plan for the spring chinook salmon of the Grande Ronde Basin. The Nez Perce Tribe, ODFW, and the Confederated Tribes of the Umatilla Indian Reservation (CTUIR) completed a formal long range plan entitled ''Grande Ronde Basin Endemic Spring Chinook Salmon Supplementation Program''. The program proposes to increase the survival of spring chinook salmon in the Grand Ronde Basin through hatchery intervention. Adult salmon from the Lostine River, Catherine Creek, and the Upper Grande Ronde River are used for a conventional supplementation program in the basin. The Nez Perce program currently operates under the ESA Section 10 Permit 1149.

    The antinutritional factors (ANFs) present in Vicia spp. seeds are a major constraint to the wider utilization of these crops as grain legumes. In the case of faba bean (Vicia faba L.), a breeding priority is the absence vicine and convicine (v-c); responsible for favism in humans and for the reduced animal performance or low egg production in laying hens. The discovery of a spontaneous mutant allele named vc-, which induces a 10-20 fold reduction of v-c contents, may facilitate the process. However, the high cost and difficulty of the chemical detection of v-c seriously restricts the advances in breeding-selection. To identify random amplified polymorphic DNA (RAPD) markers linked to this gene, we have analysed an F(2 )population derived from a cross between a line with high v-c content (Vf6) and the vc- genotype (line 1268). Quantification of v-c was done by spectrophotometry on the parents and the F(2 )population (n = 136). By using bulked segregant analysis (BSA), two RAPD markers linked in coupling and repulsion phase to the allele vc- were identified and further converted into sequence characterized amplified regions (SCARs). Amplification of SCARS was more consistent, although the initial polymorphism between pools was lost. To recover the polymorphisms several approaches were explored. Restriction digestion with HhaI (for SCAR SCH01(620)) and RsaI (for SCAR SCAB12(850)) revealed clear differences between the parental lines. The simultaneous use of the two cleavage amplified polymorphism (CAP) markers will allow the correct fingerprinting of faba bean plants and can be efficiently used in breeding selection to track the introgression of the vc- allele to develop cultivars with low v-c content and improved nutritional value.

    In 1996, construction of a hazardous waste incinerator (HWI) was initiated in Constanti, Tarragona, Spain. Because this facility was the first, and up to date, the only HWI in Spain, the concern about its potential environmental impact and health risks has been considerable in the public opinion. Regular operations in the facility started in 1999. In order to establish the potential health risks of PCDD/PCDF exposure on the general population living near the new HWI, a biological monitoring program was designed. Samples of blood, breast milk and adipose tissue were obtained during the construction period of the HWI from subjects living in the neighborhood of the facility and analyzed for baseline levels of PCDD/PCDF. Moreover, taking into account that food is the main route of exposure to PCDD/Fs, the assessment of the dietary intake of these pollutants by the population living in the area under potential influence of the HWI was also included in the monitoring program. Approximately 4 years after the new HWI began regular operations (2003), biological samples from individuals living in the same area were again collected, and PCDD/PCDF concentrations determined. The update of PCDD/PCDF intake from food is essential in order to establish clearly if any potential increase in the levels of these compounds in biological tissues of individuals living in the area under influence of the HWI could be due to environmental emissions of PCDD/PCDF by the facility or to increases of the levels of these pollutants in food. In this paper, we present the concentrations of PCDD/PCDF in biological human samples from subjects living in the vicinity of the HWI. The dietary intake of these compounds by the population in this area, after 4 years of regular operations, is also shown. Results were compared with baseline PCDD/PCDF levels obtained in 1999.

    Background: Installations that burn fossil fuels to generate power may represent a health problem due to the toxic substances which they release into the environment. Objectives: To investigate whether there might be excess mortality due to tumors of lung, larynx and bladder in the population residing near Spanish combustion installations included in the European Pollutant Emission Register. Methods: Ecologic study designed to model sex-specific standardized mortality ratios for the above three tumors in Spanish towns, over the period 1994-2003. Population exposure to pollution was estimated on the basis of distance from town of residence to pollution source. Using mixed Poisson regression models, we analyzed: risk of dying from cancer in a 5-kilometer zone around installations that commenced operations before 1990; effect of type of fuel used; and risk gradient within a 50-kilometer radius of such installations. Results: Excess mortality (relative risk, 95% confidence interval) was detected in the vicinity of pre-1990 installations for lung cancer (1.066, 1.041-1.091 in the overall population; 1.084, 1.057-1.111 in men), and laryngeal cancer among men (1.067, 0.992-1.148). Lung cancer displayed excess mortality for all types of fuel used, whereas in laryngeal and bladder cancer, the excess was associated with coal-fired industries. There was a risk gradient effect in the proximity of a number of installations. Conclusions: Our results could support the hypothesis of an association between risk of lung, laryngeal and bladder cancer mortality and proximity to Spanish combustion installations.

    Composition of three types of honey (mixed forest honey and monofloral-black locust and rapeseed honeys) originated from the vicinity of an industrial town (Košice, Slovak Republic) was compared. Higher content of minerals including toxic metals in forest honey (1358.6 ng Ni/g, 85.6 ng Pb/g, and 52.4 ng Cd/g) than in rapeseed and black locust honeys confirmed that botanical origin rather than the distance for eventual source of pollution (steel factory) affects metal deposition. Benzoic acid derivatives were typically more accumulated in forest but cinnamic acid derivatives and some flavonoids in rapeseed honey (in free and/or glycoside-bound fraction). In terms of quantity, p-hydroxybenzoic and p-coumaric acids were mainly abundant. Total phenols, thiols, and proteins were abundant in forest honey. Some metals and phenols contributed to separation of honeys based on principal component analysis (PCA). Native amount of 5-(hydroxymethyl)furfural was not related to honey type (~11 μg/g) and was elevated after strong acid hydrolysis (200-350 μg/g) but it did not interfere with the assay of phenols by Folin-Ciocalteu reagent. This is the first report of metals and metabolites in the same study, and data are discussed with available literature. We conclude that black locust (acacia) honey is the most suitable for daily use and that central European monofloral honeys contain lower amounts of toxic metals in comparison with other geographical regions.

    We present a detailed investigation of the γ-ray emission in the vicinity of the supernova remnant (SNR) W28 (G6.4–0.1) observed by the Large Area Telescope (LAT) on board the Fermi Gamma-ray Space Telescope. We detected significant γ-ray emission spatially coincident with TeV sources HESS J1800–240A, B, and C, located outside the radio boundary of the SNR. Their spectra in the 2-100 GeV band are consistent with the extrapolation of the power-law spectra of the TeV sources. We also identified a new source of GeV emission, dubbed Source W, which lies outside the boundary of TeV sources and coincides with radio emission from the western part of W28. All of the GeV γ-ray sources overlap with molecular clouds in the velocity range from 0 to 20 km s{sup –1}. Under the assumption that the γ-ray emission toward HESS J1800–240A, B, and C comes from π{sup 0} decay due to the interaction between the molecular clouds and cosmic rays (CRs) escaping from W28, they can be naturally explained by a single model in which the CR diffusion coefficient is smaller than the theoretical expectation in the interstellar space. The total energy of the CRs escaping from W28 is constrained through the same modeling to be larger than ∼2 × 10{sup 49} erg. The emission from Source W can also be explained with the same CR escape scenario.

    Chronic industrial fluoride toxicosis in the forms of dental, skeletal and non-skeletal fluorosis was investigated in 162 villagers (94 males and 78 females) above 15 years of age living in the vicinity of superphosphate fertilizer plants located approximately 12 km south of Udaipur city of Rajasthan, India. Out of these villagers, 90 (55.5%) and 29 (18.0%) were found to be afflicted with mild to severe dental and skeletal fluorosis, respectively. Dental fluorosis characterized with light to deep-brownish bilaterally striated horizontal lines, pits or patches and fine dots or granules was noted on incisor teeth of villagers. Irregular wearing, excessive corrosions (abrasions), dark-brownish pigmentation of exposed cementum and dentine material, diastem as between teeth, pronounced loss of tooth supporting bone with recession and bulging of gingiva (gum) were also present in subjects of older age group (>55 years). Among 29 (18.0%) individuals, mild to moderate manifestations of skeletal fluorosis such as crippling, kyphosis, invalidism and genu-varum syndrome were found. In these fluorotic subjects pain/rigidity in major joints viz. neck, back, hip, knee and shoulder was also found. None of the fluorotic subjects showed evidence of genu-valgum syndrome. Other signs of chronic industrial fluoride intoxication in soft tissues (non-skeletal fluorosis) included colic, intermittent diarrhoea or constipation, bloating, polyuria and polydipsia. These findings indicate that surrounding environment of superphosphate fertilizer plants is contaminated with fluoride emission, which in turn is causing diverse ill health effects in humans which are discussed.
