    The blood-brain barrier (BBB) prevents entry of most drugs into the brain and is a major hurdle to the use of drugs for brain tumors and other central nervous system disorders. Work in small animals has shown that ultrasound combined with an intravenously circulating microbubble agent can temporarily permeabilize the BBB. Here, we evaluated whether this targeted drug delivery method can be applied safely, reliably, and in a controlled manner on rhesus macaques using a focused ultrasound system. We identified a clear safety window during which BBB disruption could be produced without evident tissue damage, and the acoustic pressure amplitude where the probability for BBB disruption was 50% and was found to be half of the value that would produce tissue damage. Acoustic emission measurements seem promising for predicting BBB disruption and damage. In addition, we conducted repeated BBB disruption to central visual field targets over several weeks in animals trained to conduct complex visual acuity tasks. All animals recovered from each session without behavioral deficits, visual deficits, or loss in visual acuity. Together, our findings show that BBB disruption can be reliably and repeatedly produced without evident histologic or functional damage in a clinically relevant animal model using a clinical device. These results therefore support clinical testing of this noninvasive-targeted drug delivery method.

  5. The Temporary Leave Dilemma -

    2010-01-01

    Lone mothers have to take care of a sick child with little or no help from the child’s other parent and have to carry all costs connected to leave-taking. This paper empirically tests whether lone mothers take more temporary parental leave to care for sick children than partnered mothers...... and whether parental leave is associated with a signaling cost. The results from this study of Swedish mothers show that lone mothers use more temporary parental leave than partnered mothers. Further, within the group of lone mothers, those with higher socioeconomic status take less temporary parental leave...... than those with lower socioeconomic status, whereas no such differences are found within the group of partnered mothers. One possible interpretation is that signaling costs negatively influence the utilization of temporary parental leave for lone mothers....

  6. Temporary physical protection systems

    1991-01-01

    Terrorism and other aspects of world political instability have created a high demand for temporary physical protection systems within the nuclear materials management community. They can be used when vehicles carrying important assets are away from their permanent fixed site location, around areas where experiments are being temporarily conducted, around construction areas and one portions of a fixed site physical security system which is temporarily inoperable. Physical security systems can be grouped into four categories: tactical, portable, semi-permanent, and fixed. The resources and experience gained at Sandia National Laboratories in over forty years of developing and implementing security systems for protecting nuclear weapons and fixed nuclear facilities is now being applied to temporary physical security systems. This paper emphasizes temporary physical security systems and their component parts that are presently available and identify additional system-subsystem objectives, requirements, and concepts

  16. A temporary index

    Thomson, Jon; Craighead, Alison

    2015-01-01

    The ongoing management of low, intermediate and high-level nuclear waste is an unresolved issue for humanity, not least because the time-frames in question when dealing with the hazards of radioactive wastes, range from as little as a few tens of years to more than 100 000 years. It is from this starting point that we are beginning the development of an ambitious multifaceted artwork aiming to help us consider our relationship with deep-time and our nuclear legacy. The expressed aim of Temporary Index is to raise general awareness about these long-term management issues, and in doing so, to embed this knowledge into our collective cultural memory so as to transmit useful information about our nuclear waste into the future. We wish to create a series of decorative, real-time numeric counters based on the probabilistic decay (including decay of daughter products) of existing nuclear waste that we identify from the earliest weapons' development programmes in the United States right through to contemporary wastes being produced by nuclear energy production today across the world. Each display will countdown in seconds, showing the time remaining before the given item of waste (or a particular site) is considered safe to humans. A hypothetical example of one counter could be a bottle of sludge containing plutonium discovered in 2004 during an attempted clean-up of the Hanford nuclear site in Washington State, United States. Another example might be the geological storage facility for vitrified nuclear waste at Horonobe in Japan, should it be established in the future. Accident sites, such as Chernobyl or Fukushima Daiichi could also be tagged with counters, as could low-level waste (LLW) repositories such as the one at Drigg near Sellafield in the United Kingdom. Whatever the items identified and this will be a complex process requiring collaboration with experts in the field, it is important that a wide range of short- and long-term counters are established to

    Virtanen, Marianna; Kivimäki, Mika; Joensuu, Matti; Virtanen, Pekka; Elovainio, Marko; Vahtera, Jussi

    2005-06-01

    We aimed to review evidence on the relationship between temporary employment and health, and to see whether the association is dependent on outcome measure, instability of employment, and contextual factors. We systematically searched for studies of temporary employment and various health outcomes and critically appraised 27 studies. The review suggests higher psychological morbidity among temporary workers compared with permanent employees. According to some studies, temporary workers also have a higher risk of occupational injuries but their sickness absence is lower. Morbidity may be higher in temporary jobs with high employment instability and in countries with a lower number of temporary workers and unemployed workers. The evidence indicates an association between temporary employment and psychological morbidity. The health risk may depend on instability of temporary employment and the context. Confounding by occupation may have biased some of the studies. Additional research to clarify the role of employment instability, hazard accumulation, and selection is recommended.

    Full Text Available Among the experimental actions fostered so far by the Compagnia di San Paolo through its Housing Program, committed in handling the complex and fragmented housing discomfort issue, the Temporary Dwellings initiative represents a unique and innovative experience, as it actually offers the chance to activate a proper managerial direction around and about the real estate development processes. In particular, the Temporary Dwellings action is marked by two key aspects: a structured co-planning vision and projects selected through a requests for proposal system. The process in the whole aims on the one hand at reaching an high transparent level of decision making , while, on the other hand, at developing a continuous and mutual monitoring and matching activity between the Housing Program and the group of cross-curricular experts teamed up in the project: technicians, designers, managers, psychologists, contractors, and the other local stakeholders.

  5. Large capacity temporary visual memory

    Science.gov (United States)

    Endress, Ansgar D.; Potter, Mary C.

    2014-01-01

    Visual working memory (WM) capacity is thought to be limited to three or four items. However, many cognitive activities seem to require larger temporary memory stores. Here, we provide evidence for a temporary memory store with much larger capacity than past WM capacity estimates. Further, based on previous WM research, we show that a single factor — proactive interference — is sufficient to bring capacity estimates down to the range of previous WM capacity estimates. Participants saw a rapid serial visual presentation (RSVP) of 5 to 21 pictures of familiar objects or words presented at rates of 4/s or 8/s, respectively, and thus too fast for strategies such as rehearsal. Recognition memory was tested with a single probe item. When new items were used on all trials, no fixed memory capacities were observed, with estimates of up to 9.1 retained pictures for 21-item lists, and up to 30.0 retained pictures for 100-item lists, and no clear upper bound to how many items could be retained. Further, memory items were not stored in a temporally stable form of memory, but decayed almost completely after a few minutes. In contrast, when, as in most WM experiments, a small set of items was reused across all trials, thus creating proactive interference among items, capacity remained in the range reported in previous WM experiments. These results show that humans have a large-capacity temporary memory store in the absence of proactive interference, and raise the question of whether temporary memory in everyday cognitive processing is severely limited as in WM experiments, or has the much larger capacity found in the present experiments.

    Jokela, J.; Olin, J.; Koukkari, H.

    1983-05-01

    This report deals with materials and structures of temporary air-raid shelters. At first, the weapon effects against which the temporary shelters can protect are described. These are, primarily, the fragmentation and blast pressure caused by conventional weapons and those effects of the nuclear weapons which exist outside the total disaster and fire areas. Temporary shelters built into existing buildings can give protection either from radioactive fallout or from fallout and collapse of the building above. For fallout protection heavy materials are needed, which simultaneously protect from fragmentation. In the research report, the methods and materials used for the contruction of a fallout shelter into an apartment house and a small house are introduced. The collapse loads acting on a basement ceiling and the design of additional timber supports are also presented. The use of various materials in the construction of shelters outside the buildings are introduced. Separate shelters can be built either under the ground or on the ground. The same materials can be used in both cases, but the underground shelters have a better level of protection. (author)

    Full Text Available The paper deals with temporary employment in the Russian labour market. The main focus is the gender difference regarding determinants of temporary employment. Unlike most European countries, where women are more likely to have temporary work, in Russia men predominantly have this status, comparable to the situation in many developing countries. This paper seeks to understand why this is the case. The household survey of NOBUS (held in 2003 by State Statistical Centre with World Bank participation is used to answer this question: the results suggest that gender differences in temporary employment do exist, and that the main factors that explain these differences are education, and marital status.

  20. [Temporary disability and its legal implications].

    Science.gov (United States)

    Martin-Fumadó, Carles; Martí Amengual, Gabriel; Puig Bausili, Lluïsa; Arimany-Manso, Josep

    2014-03-01

    Temporary disability is the condition that workers face when, as the result of illness (common or professional) or accident (work-related or not), they are temporarily prevented from performing their work and require health care. The management of temporary disability is a medical act that involves (in addition to a complex clinical assessment) obvious social, occupational and financial connotations and requires continuing medical follow-up from doctors, as well as responses to medical-legal conflicts. The regulatory framework on the subject is extensive in the Spanish setting and highly diverse in the European setting. Beyond the regulatory framework, the repercussions of temporary disability are self-evident at all levels. Although determining temporary disability is a common medical act for practicing physicians, it is not exempt from risks or difficulties arising from the assessment itself and the characteristics of practicing medical care. Established medical-legal conflicts include the processing of health data and the requirements for transferring information related to workers' temporary disability to their company's medical services. The interest and usefulness demonstrated by the data obtained from forensic medicine for public health require the incorporation of these data into general healthcare information, as it could be essential to the surveillance of worker health. The recommendations established by medical societies, as good practice guidelines, are especially useful in this type of conflict. Copyright © 2014 Elsevier España, S.L. All rights reserved.

    A case of temporary quadriplegia following a continuous thoracic paravertebral block in an adult patient scheduled for video-assisted thoracoscopy is presented. An 18-gauge Tuohy needle was inserted under direct vision by the surgeon but the tip of the catheter was not localized. Postoperatively, the patient developed temporary quadriplegia 90 minutes after the start of a continuous infusion of ropivacaine 0.2%. Imaging studies showed that the catheter was localized in the intrathecal space. Copyright © 2012 Elsevier Inc. All rights reserved.

  5. Meaningful radiation worker training for temporary craftsmen

    International Nuclear Information System (INIS)

    Williams, S.L.

    1976-01-01

    The carefully organized Radiation Worker Training Program presented to permanently assigned personnel at a power reactor facility too often falls by the wayside when temporary craftsmen are brought in for an outage. Even though these temporary workers will frequently be assigned to outage jobs with high radiation and/or contamination exposures, their Radiation Worker Training is often squeezed into an already busy schedule, thus reducing its effectiveness. As an aid for evaluating the effectiveness of an existing Radiation Worker Training Program for temporary craftsmen or for setting up a new program, the following guides are presented and discussed in this paper: the training environment; the interest and meaningfulness of the presentation; the method or methods used for presentation of the training information; the use of demonstrations; trainee participation; and, measuring the amount and type of information retained by a trainee. Meaningful Radiation Worker Training for temporary craftsmen can pay big dividends. Craftsmen can be expected to make fewer mistakes, thus reducing radiation exposure and lessening the chance for the spread of contamination. The craftsmen will also benefit by being able to work longer and utility management will benefit by having lower outage costs

    2013-08-01

    There are many issues regarding the use of real patients in objective structured clinical examinations (OSCEs). In dermatology OSCE stations, standardised patients (SPs) with clinical photographs are often used. Temporary transfer tattoos can potentially simulate skin lesions when applied to an SP. This study aims to appraise the use of temporary malignant melanoma tattoos within an OSCE framework. Within an 11-station OSCE, a temporary malignant melanoma tattoo was developed and applied to SPs in a 'skin lesion' OSCE station. A questionnaire captured the opinions of the candidate, SP and examiners, and the degree of perceived realism of each station was determined. Standard post hoc OSCE analysis determined the psychometric reliability of the stations. The response rates were 95.9 per cent of candidates and 100 per cent of the examiners and SPs. The 'skin lesion' station achieved the highest realism score compared with other stations: 89.0 per cent of candidates felt that the skin lesion appeared realistic; only 28 per cent of candidates had ever seen a melanoma before in training. The psychometric performance of the melanoma station was comparable with, and in many instances better than, other OSCE stations. Transfer tattoo technology facilitates a realistic dermatology OSCE station encounter. Temporary tattoos, alongside trained SPs, provide an authentic, standardised and reliable experience, allowing the assessment of integrated dermatology clinical skills. © 2013 John Wiley & Sons Ltd.

  20. Temporary refugia for coral reefs in a warming world

    Science.gov (United States)

    van Hooidonk, R.; Maynard, J. A.; Planes, S.

    2013-05-01

    Climate-change impacts on coral reefs are expected to include temperature-induced spatially extensive bleaching events. Bleaching causes mortality when temperature stress persists but exposure to bleaching conditions is not expected to be spatially uniform at the regional or global scale. Here we show the first maps of global projections of bleaching conditions based on ensembles of IPCC AR5 (ref. ) models forced with the new Representative Concentration Pathways (RCPs). For the three RCPs with larger CO2 emissions (RCP 4.5, 6.0 and 8.5) the onset of annual bleaching conditions is associated with ~ 510ppm CO2 equivalent; the median year of all locations is 2040 for the fossil-fuel aggressive RCP 8.5. Spatial patterns in the onset of annual bleaching conditions are similar for each of the RCPs. For RCP 8.5, 26% of reef cells are projected to experience annual bleaching conditions more than 5 years later than the median. Some of these temporary refugia include the western Indian Ocean, Thailand, the southern Great Barrier Reef and central French Polynesia. A reduction in the growth of greenhouse-gas emissions corresponding to the difference between RCP 8.5 and 6.0 delays annual bleaching in ~ 23% of reef cells more than two decades, which might conceivably increase the potential for these reefs to cope with these changes.

  1. Tocopherol in irradiation of temporary hypoxic tumours

    International Nuclear Information System (INIS)

    Kaagerud, A.; Lund, N.; Peterson, H.I.

    1981-01-01

    The influence of tocopherol on the effect of local irradiation under induced ischaemia by temporary tourniquet of two rat tumours transplanted intramuscularly into one hindleg was evaluated. An impaired retardation of growth rate occurred in tumours irradiated under ischaemia. This effect was eliminated by pretreatment of animals with tocopherol. In separate experiments the method of inducing ischaemia was investigated by MDO-electrode measurements of tumour tissue oxygen pressure. A significant tumour hypoxia was found under tourniquet of the tumour-bearing leg of the animals. Pretreatment with tocopherol did not influence the tumour pO 2 . (Auth.)

  5. Information barriers

    International Nuclear Information System (INIS)

    Fuller, J.L.; Wolford, J.

    2001-01-01

    Full text: An information barrier (IB) consists of procedures and technology that prevent the release of sensitive information during a joint inspection of a sensitive nuclear item, and provides confidence that the measurement system into which it has been integrated functions exactly as designed and constructed. Work in the U.S. on radiation detection system information barriers dates back at least to 1990, even though the terminology is more recent. In January 1999 the Joint DoD-DOE Information Barrier Working Group was formed in the United States to help coordinate technical efforts related to information barrier R and D. This paper presents an overview of the efforts of this group, by its Chairs, as well as recommendations for further information barrier R and D. Progress on the demonstration of monitoring systems containing IBs is also provided. From the U.S. perspective, the basic, top-level functional requirements for the information barrier portion of an integrated radiation signature-information barrier inspection system are twofold: The host must be assured that his classified information is protected from disclosure to the inspecting party; and The inspecting party must be confident that the integrated inspection system measures, processes, and presents the radiation-signature-based measurement conclusion in an accurate and reproducible manner. It is the position of the United States that in the absence of any agreement to share classified nuclear weapons design information in the conduct of an inspection regime, the requirement to protect host country classified warhead design information is paramount and admits no tradeoff versus the confidence provided to the inspecting party in the accuracy and reproducibility of the measurements. The U.S. has reached an internal consensus on several critical design elements that define a general standard for radiation signature information barrier design. These criteria have stood the test of time under intense

    Temporary henna tattoos have become increasingly widespread among children and young people, especially in holiday spots in recent years. Although reactions to henna tattoo are becoming progressively more common, only few cases of a henna pseudo-tattoo resulting in temporary hypertrichosis have been reported so far. Here, we have reported a 5-year-old girl who developed allergic contact dermatitis and localized hypertrichosis on her right arm after application of temporary henna tattoo during summer holiday.

    2014-04-01

    We estimate the nutrient budget in a temporary Mediterranean river basin. We use field monitoring and modelling tools to estimate nutrient sources and transfer in both high and low flow conditions. Inverse modelling by the help of PHREEQC model validated the hypothesis of a losing stream during the dry period. Soil and Water Assessment Tool model captured the water quality of the basin. The 'total daily maximum load' approach is used to estimate the nutrient flux status by flow class, indicating that almost 60% of the river network fails to meet nitrogen criteria and 50% phosphate criteria. We recommend that existing well-documented remediation measures such as reforestation of the riparian area or composting of food process biosolids should be implemented to achieve load reduction in close conjunction with social needs.

  11. Temporary Immersion System for Date Palm Micropropagation.

    Othmani, Ahmed; Bayoudh, Chokri; Sellemi, Amel; Drira, Noureddine

    2017-01-01

    The temporary immersion system (TIS) is being used with tremendous success for automation of micropropagation of many plant species. TIS usually consists of a culture vessel comprising two compartments, an upper one with the plant material and a lower one with the liquid culture medium and an automated air pump. The latter enables contact between all parts of the explants and the liquid medium by setting overpressure to the lower part of the container. These systems are providing the most satisfactory conditions for date palm regeneration via shoot organogenesis and allow a significant increase of multiplication rate (5.5-fold in comparison with that regenerated on agar-solidified medium) and plant material quality, thereby reducing production cost.

  12. Temporary fire sealing of penetrations on TFTR

    International Nuclear Information System (INIS)

    Hondorp, H.L.

    1981-02-01

    The radiation shielding provided for TFTR for D-D and D-T operation will be penetrated by numerous electrical and mechanical services. Eventually, these penetrations will have to be sealed to provide the required fire resistance, tritium sealability, pressure integrity and radiation attenuation. For the initial hydrogen operation, however, fire sealing of the penetrations in the walls and floor is the primary concern. This report provides a discussion of the required and desirable properties of a temporary seal which can be used to seal these penetrations for the hydrogen operation and then subsequently be removed and replaced as required for the D-D and D-T operations. Several candidate designs are discussed and evaluated and recommendations are made for specific applications

    2012-01-01

    The purpose of the study was to examine time to reversal of a temporary ostomy, reasons for delayed closure, and patient satisfaction with the scheduling of their closure and related hospital care. Cross-sectional, descriptive study. The target population comprised patients who underwent creation of a temporary ostomy and reversal surgery within one National Health System Hospital Trust in the United Kingdom. The population served by this Trust are ethnically and socioeconomically diverse, predominantly living in urban areas around Greater London. Sixty-one persons who met inclusion criteria were identified. A two-step analytical process was undertaken. First, a literature review examining incidence and causes of delayed stoma closure was undertaken. Second, a postal survey of all patients who had had their stoma closed in 2009 was conducted. Respondents were allowed 2 weeks to complete and return the questionnaire. The survey instrument was developed locally and subjected to content validation using ostomy patients, surgical and nursing colleagues. It consisted of 9 questions querying time from original surgery to closure, reasons for delaying closure surgery beyond 12 weeks, and satisfaction with care. Twenty-seven patients returned their questionnaires, indicating they consented to participate; a response rate of 44%. Half of the respondents (n = 14 [52%]) underwent closure surgery within 6 months of stoma formation; the remaining 48% waited more than 6 months (median: 6.5 months, range: 1.5-26 months). Thirteen patients (48%) reported a delay in receiving their stoma closure; the main reason cited was the need for a course of adjuvant postoperative chemotherapy. Three quarters of respondents (22 [74%]) were satisfied with the overall care they received. Findings from this study suggest that stoma closure may be associated with fewest complications if performed before 12 weeks.

    2017-06-01

    Full Text Available The aim of this article is to describe and explain the development of temporary employment in Sweden between 1992 and 2010, and to investigate the effect of temporary employment for individuals’ future career on the labor market. The article analyzes temporary employees’ status transitions on the labor market using Swedish Labour Force Survey (LFS data for the period 1992–2010. Each cohort consists of 2-year panels and focuses on changes between the first and last measuring points. The findings indicate that the specific type of temporary employment is crucial as regards whether or not it constitutes a stepping-stone toward permanent employment. The chances are greater in the case of, for example, substitutes, but are considerably less in the case of on-call employment. Certain types of temporary employment thus seem to be used by the employer to screen the employability of the employee, while others are used for achieving flexibility

    2000-01-01

    Full Text Available PURPOSE:To determine the indication for and incidence and evolution of temporary and permanent pacemaker implantation in cardiac transplant recipients. METHODS: A retrospective review of 114 patients who underwent orthotopic heart transplantation InCor (Heart Institute USP BR between March 1985 and May 1993. We studied the incidence of and indication for temporary pacing, the relationship between pacing and rejection, the need for pemanent pacing and the clinical follow-up. RESULTS: Fourteen of 114 (12%heart transplant recipients required temporary pacing and 4 of 114 (3.5% patients required permanent pacing. The indication for temporary pacing was sinus node dysfunction in 11 patients (78.5% and atrioventricular (AV block in 3 patients (21.4%. The indication for permanent pacemaker implantation was sinus node dysfunction in 3 patients (75% and atrioventricular (AV block in 1 patient (25%. We observed rejection in 3 patients (21.4% who required temporary pacing and in 2 patients (50% who required permanent pacing. The previous use of amiodarone was observed in 10 patients (71.4% with temporary pacing. Seven of the 14 patients (50% died during follow-up. CONCLUSION: Sinus node dysfunction was the principal indication for temporary and permanent pacemaker implantation in cardiac transplant recipients. The need for pacing was related to worse prognosis after cardiac transplantation.

    Full Text Available BACKGROUND Contraceptive advice is a component of good preventive healthcare. Socioeconomic factors, education are a few of factors that play vital role in family planning acceptance. To provide this, understanding the attitude and knowledge of patient towards contraception is very much necessary. Objective of this study is to assess the awareness and acceptance of temporary methods of contraception in postpartum primiparas during their first visit to Family Planning OPD, MCH, Kottayam. MATERIALS AND METHODS A hospital-based prospective descriptive study was conducted among the primiparas presented in Family Planning OPD for the first time in postpartum at 6 wks. in MCH during the study period. Informed written consent was obtained from the patients. The study subjects were interviewed with questionnaire to assess the awareness and acceptance of temporary contraceptive methods and the level to which each of them will keep compliance. The questionnaire was to elicit information regarding age, educational status, occupation, knowledge and source of contraceptive methods, attitude of female towards contraception. RESULTS In our study, majority include graduates (37%, but most of study population were unemployed (43.2%. Literate people are more conscious about their own health and that of their families and try to limit their families much more effectively than the illiterates do. The awareness of the group about contraception was 80.5%, mostly through health workers, 39.6%. 53.9% of the study population had accepted any of the temporary contraceptive methods; maximum opted being the barrier contraception, 19%. 60.9% had peer group support. 74.5% had antenatal counselling from a healthcare worker regarding the use of temporary contraceptive methods. Acceptance was maximum among the graduated subjects, 66.9%.The type accepted by graduates include mostly barrier. Contraceptives, 23.2%. 48% of the graduates used for the need of spacing.

    When it is possible that the employee's work ability can be restored through treatment or rehabilitation, disability pension in Finland is granted for a fixed period. We examined which factors are associated with return to work (RTW) after such temporary disability pension. The study included all Finnish residents whose temporary disability pension from the earnings-related pension system started in 2008 (N = 10,269). Competing risks regression analysis was applied to examine register-based determinants for RTW after temporary disability pension due to mental disorders, musculoskeletal diseases, other diseases, and injury over a 4-year follow-up period. The overall cumulative incidence of RTW was 25%. RTW was more probable after temporary disability pension due to injury and musculoskeletal diseases and less probable after temporary disability pension due to mental disorders. Younger age and higher education increased RTW but differences between genders, private and public sector employees, and occupational classes were relatively small. The probability of RTW was higher among those who were employed before their temporary disability pension (subhazard ratio in multivariate analysis 2.41 (95% CI 2.13-2.72) and among the 9% who participated in vocational rehabilitation during their pension [SHR 2.10 (95% CI 1.90-2.31)]. With some exceptions, the results were fairly similar for all diagnostic causes of temporary disability pension. Return to work after temporary disability pension was relatively uncommon. Nevertheless, in all diagnostic groups RTW continued for the whole follow-up period. The low educated and those not employed before temporary disability pension need more support in their RTW. The strong association between vocational rehabilitation and RTW suggests that increasing rehabilitation among those with impaired work ability may promote RTW.

    2016-09-01

    Screen-printed sensor for measuring human pulse was designed and first tests using a demonstrator device were conducted. Various materials and sensors' set ups were compared and the results are presented as the starting point for fabrication of fully functional device. As a screen printing substrate, commercially available temporary tattoo paper was used. Using previously developed nanomaterials-based pastes design of a pressure sensor was printed on the paper and attached to the epidermis. Measurements were aimed at determining sensors impedance constant component and its variability due to pressure wave caused by the human pulse. The constant component was ranging from 2kΩ to 6kΩ and the variations of the impedance were ranging from +/-200Ω to +/-2.5kΩ, depending on the materials used and the sensor's configuration. Calculated signal-to-noise ratio was 3.56:1 for the configuration yielding the highest signal level. As the device's net impedance influences the effectiveness of the wireless communication, the results presented allow for proper design of the sensor for future health-monitoring devices.

    Abstract Electrically interfacing the skin for monitoring personal health condition is the basis of skin‐contact electrophysiology. In the clinical practice the use of stiff and bulky pregelled or dry electrodes, in contrast to the soft body tissues, imposes severe restrictions to user comfort and mobility while limiting clinical applications. Here, in this work dry, unperceivable temporary tattoo electrodes are presented. Customized single or multielectrode arrays are readily fabricated by inkjet printing of conducting polymer onto commercial decal transfer paper, which allows for easy transfer on the user's skin. Conformal adhesion to the skin is provided thanks to their ultralow thickness (Tattoo electrode–skin contact impedance is characterized on short‐ (1 h) and long‐term (48 h) and compared with standard pregelled and dry electrodes. The viability in electrophysiology is validated by surface electromyography and electrocardiography recordings on various locations on limbs and face. A novel concept of tattoo as perforable skin‐contact electrode, through which hairs can grow, is demonstrated, thus permitting to envision very long‐term recordings on areas with high hair density. The proposed materials and patterning strategy make this technology amenable for large‐scale production of low‐cost sensing devices. PMID:29593975

  16. Temporary intestinal ischemia for radiation protection

    International Nuclear Information System (INIS)

    Lote, K.

    1983-01-01

    The most important determinant of cellular radiosensivity is the tissue oxygen content at the time of irradiation. The purpose of the present experimental work was to assess a new iscemia-inducing method in order to reduce normal tissue radiation damage during radiotherapy. Temporary ischemia was induced in a cat small intestine by degraded starch microspheres. Regional arterial and tissue blod flow immediately fell by 85% with subsequent normalization within 26 minutes after microsphere injection. No tendency of small vessel thrombosis caused by starch sphere embolization in combination with previous or current intestinal irradiation was detected. Starch sphere remenants were rapidly engulfed by, and persisted within tissue macrophages for 14 days without causing intestinal inflammatory reactions. In vitro studies showed that human platelets neither adhered to nor were aggregated by starch microspheres. The new method, wich occlude arteriolar vessels distal to the mesentric arterial arcades and thus largely excludes collateral blood flow, seems suited to provide effictive and selective feline small intestinal hypoxic radiation protection. This conclusion may also be valid in man

    The work in the ESDRED In te grated Project Module 4, Temporary Sealing (using low pH cement) Technology, consisted first of designing a low pH cement formulation and then of preparing several concrete designs suitable for the construction of sealing plugs and for rock support using shot crete techniques. Regarding sealing plugs, a short plug was constructed at Aspo in Sweden and it was very quickly loaded to failure i.e. slippage by applying water pressure to one face. A second, full scale plug was subsequently constructed at Grimsel test site in Switzerland. It was loaded using the swelling pressure created by bentonite blocks which were artificially hydrated. At time of writing the targeted pressure on the plug was not reached. As the saturation of the bentonite is taking longer than expected the partners involved agreed to continue with the saturation of the bentonite blocks and the related data monitoring beyond the ESDRED Project. The studies on low-pH shot crete for rock sup port were based on available recipes of low-pH concrete mixtures for use in a repository. Pilot and full scale tests were carried out in Sweden and in Switzerland. (Author) 5 refs.

    To asses the indications and complications of temporary loop ileostomy. This was a prospective cohort study conducted at Isra University Hospital, Hyderabad, Pakistan between February 2003 and August 2006. All patients who had temporary loop ileostomy during that period were included in this study. The indications and various postoperative complications were noted during postoperative hospital stay and subsequently during follow up till stoma were closed. Fifty six patients fulfilled the selection criteria during the study period. Typhoid (enteric) perforation was the most common indication of loop ileostomy accounting for about two thirds of all cases. Other indications were iatrogenic, covering ileostomy for rectal cancers, following resection anastomosis, tuberculosis, blunt abdominal trauma, anastomosis leak and rectovaginal fistula. Post operative skin excoriation was the most common complication while poor siting, transient edema, retraction and high output were other less common complications. Temporary loop ileostomy is the stoma of choice for temporary faecal diversion as most of its complications are manageable conservatively. (author)

    1998-01-01

    Purpose: We describe the results of a preliminary prospective study using different recently developed temporary and retrievable inferior vena cava (IVC) filters.Methods: Fifty temporary IVC filters (Guenther, Guenther Tulip, Antheor) were inserted in 47 patients when the required period of protection against pulmonary embolism (PE) was estimated to be less than 2 weeks. The indications were documented deep vein thrombosis (DVT) and temporary contraindications for anticoagulation, a high risk for PE, and PE despite DVT prophylaxis.Results: Filters were removed 1-12 days after placement and nine (18%) had captured thrombi. Complications were one PE during and after removal of a filter, two minor filter migrations, and one IVC thrombosis.Conclusion: Temporary filters are effective in trapping clots and protecting against PE, and the complication rate does not exceed that of permanent filters. They are an alternative when protection from PE is required temporarily, and should be considered in patients with a normal life expectancy.

    Radionuclides of various half lives have been in use for several years years at different Departments of king Abdulaziz university, the university hospital, and research center. The use of unsealed radionuclides in many laboratories, resulted in considerable amounts of solid and liquid radwaste, mainly radiopharmaceuticals. To avoid accumulation of radwastes in working areas, a temporary radioactive waste storage facility was built. Segregation of radwastes according to type was carried out, followed by collection into appropriate containers and transfer to the storage facility. Average radiation dose rate inside the store was maintained at about 75 {mu} h{sup -1} through use of appropriate shielding. The dose rates at points one meter outside the store walls were maintained at about 15-20 {mu}Sv h{sup -1}. Utilization of radioisotopes during the period of 1991-1995 resulted in a volume of about 1.8 m{sup 3} of solid radwaste and about 200 L of liquid radwaste. Records of the store inventory are maintained in a computer database, listing dates, types, activities and packaging data pertinent to the radwastes delivered to the store. Quality assurance procedures are implemented during the different stages of the radwaste collection, transportation, and storage. Construction and operation of the storage facility comply with radiation safety requirements for the workers handling the radwastes, the public and the environment. The capacity of the storage facility is such that it will accommodate storage of generated radwastes of long half life up to year 2016. Permanent disposal of such radwastes may be indicated afterwards. 2 figs., 3 tabs.

  8. Temporary jobs and the severity of workplace accidents.

    Picchio, Matteo; van Ours, Jan C

    2017-06-01

    From the point of view of workplace safety, it is important to know whether having a temporary job has an effect on the severity of workplace accidents. We present an empirical analysis on the severity of workplace accidents by type of contract. We used microdata collected by the Italian national institute managing the mandatory insurance against work related accidents. We estimated linear models for a measure of the severity of the workplace accident. We controlled for time-invariant fixed effects at worker and firm levels to disentangle the impact of the type of contract from the spurious one induced by unobservables at worker and firm levels. Workers with a temporary contract, if subject to a workplace accident, were more likely to be confronted with severe injuries than permanent workers. When correcting the statistical analysis for injury under-reporting of temporary workers, we found that most of, but not all, the effect is driven by the under-reporting bias. The effect of temporary contracts on the injury severity survived the inclusion of worker and firm fixed effects and the correction for temporary workers' injury under-reporting. This, however, does not exclude the possibility that, within firms, the nature of the work may vary between different categories of workers. For example, temporary workers might be more likely to be assigned dangerous tasks because they might have less bargaining power. The findings will help in designing public policy effective in increasing temporary workers' safety at work and limiting their injury under-reporting. Copyright © 2017. Published by Elsevier Ltd.

  9. Temporary Cementitious Sealers in Enhanced Geothermal Systems

    Energy Technology Data Exchange (ETDEWEB)

    Sugama T.; Pyatina, T.; Butcher, T.; Brothers, L.; Bour, D.

    2011-12-31

    Unlike conventional hydrothennal geothermal technology that utilizes hot water as the energy conversion resources tapped from natural hydrothermal reservoir located at {approx}10 km below the ground surface, Enhanced Geothermal System (EGS) must create a hydrothermal reservoir in a hot rock stratum at temperatures {ge}200 C, present in {approx}5 km deep underground by employing hydraulic fracturing. This is the process of initiating and propagating a fracture as well as opening pre-existing fractures in a rock layer. In this operation, a considerable attention is paid to the pre-existing fractures and pressure-generated ones made in the underground foundation during drilling and logging. These fractures in terms of lost circulation zones often cause the wastage of a substantial amount of the circulated water-based drilling fluid or mud. Thus, such lost circulation zones must be plugged by sealing materials, so that the drilling operation can resume and continue. Next, one important consideration is the fact that the sealers must be disintegrated by highly pressured water to reopen the plugged fractures and to promote the propagation of reopened fractures. In response to this need, the objective of this phase I project in FYs 2009-2011 was to develop temporary cementitious fracture sealing materials possessing self-degradable properties generating when {ge} 200 C-heated scalers came in contact with water. At BNL, we formulated two types of non-Portland cementitious systems using inexpensive industrial by-products with pozzolanic properties, such as granulated blast-furnace slag from the steel industries, and fly ashes from coal-combustion power plants. These byproducts were activated by sodium silicate to initiate their pozzolanic reactions, and to create a cemetitious structure. One developed system was sodium silicate alkali-activated slag/Class C fly ash (AASC); the other was sodium silicate alkali-activated slag/Class F fly ash (AASF) as the binder of temper

    Various methods and systems are provided for smart parking barriers. In one example, among others, a smart parking barrier system includes a movable parking barrier located at one end of a parking space, a barrier drive configured to control positioning of the movable parking barrier, and a parking controller configured to initiate movement of the parking barrier, via the barrier drive. The movable parking barrier can be positioned between a first position that restricts access to the parking space and a second position that allows access to the parking space. The parking controller can initiate movement of the movable parking barrier in response to a positive identification of an individual allowed to use the parking space. The parking controller can identify the individual through, e.g., a RFID tag, a mobile device (e.g., a remote control, smartphone, tablet, etc.), an access card, biometric information, or other appropriate identifier.

  11. Temporary brittle bone disease: fractures in medical care.

    Science.gov (United States)

    Paterson, Colin R

    2009-12-01

    Temporary brittle bone disease is the name given to a syndrome first reported in 1990, in which fractures occur in infants in the first year of life. The fractures include rib fractures and metaphyseal fractures which are mostly asymptomatic. The radiological features of this disorder mimic those often ascribed to typical non-accidental injury. The subject has been controversial, some authors suggesting that the disorder does not exist. This study reports five infants with typical features of temporary brittle bone disease in whom all or most of the fractures took place while in hospital. A non-accidental cause can be eliminated with some confidence, and these cases provide evidence in support of the existence of temporary brittle bone disease.

    Soil observations networks at the national scale play an integral role in hydrologic modeling, drought assessment, agricultural decision support, and our ability to understand climate change. Understanding soil moisture variability is necessary to apply these measurements to model calibration, business and consumer applications, or even human health issues. The installation of soil moisture sensors as sparse, national networks is necessitated by limited financial resources. However, this results in the incomplete sampling of the local heterogeneity of soil type, vegetation cover, topography, and the fine spatial distribution of precipitation events. To this end, temporary networks can be installed in the areas surrounding a permanent installation within a sparse network. The temporary networks deployed in this study provide a more representative average at the 3 km and 9 km scales, localized about the permanent gauge. The value of such temporary networks is demonstrated at test sites in Millbrook, New York and Crossville, Tennessee. The capacity of a single U.S. Climate Reference Network (USCRN) sensor set to approximate the average of a temporary network at the 3 km and 9 km scales using a simple linear scaling function is tested. The capacity of a temporary network to provide reliable estimates with diminishing numbers of sensors, the temporal stability of those networks, and ultimately, the relationship of the variability of those networks to soil moisture conditions at the permanent sensor are investigated. In this manner, this work demonstrates the single-season installation of a temporary network as a mechanism to characterize the soil moisture variability at a permanent gauge within a sparse network.

  13. Temporary sharing prompts unrestrained disclosures that leave lasting negative impressions.

    Science.gov (United States)

    Hofstetter, Reto; Rüppell, Roland; John, Leslie K

    2017-11-07

    With the advent of social media, the impressions people make on others are based increasingly on their digital disclosures. However, digital disclosures can come back to haunt, making it challenging for people to manage the impressions they make. In field and online experiments in which participants take, share, and evaluate self-photographs ("selfies"), we show that, paradoxically, these challenges can be exacerbated by temporary-sharing media-technologies that prevent content from being stored permanently. Relative to permanent sharing, temporary sharing affects both whether and what people reveal. Specifically, temporary sharing increases compliance with the request to take a selfie (study 1) and induces greater disclosure risks (i.e., people exhibit greater disinhibition in their selfies, studies 1 and 2). This increased disclosure is driven by reduced privacy concerns (study 2). However, observers' impressions of sharers are insensitive to permanence (i.e., whether the selfie was shared temporarily versus permanently) and are instead driven by the disinhibition exhibited in the selfie (studies 4-7). As a result, induced by the promise of temporary sharing, sharers of uninhibited selfies come across as having worse judgment than those who share relatively discreet selfies (studies 1, 2, and 4-7)-an attributional pattern that is unanticipated by sharers (study 3), that persists days after the selfie has disappeared (study 5), is robust to personal experience with temporary sharing (studies 6A and 6B), and holds even among friends (studies 7A and 7B). Temporary sharing may bring back forgetting, but not without introducing new (self-presentational) challenges. Copyright © 2017 the Author(s). Published by PNAS.

    From patients of intensive care unit suffering from acute myocardial infarction, decompensated hypertension with left heart insufficiency, severe coronary heart disease, pulmonary infarction, cerebral ischemia 102 were selected with suspicion of hyperthyroidism because of clinical signs. 12 patients fulfilled the criteria of temporary hyperthyroidism, 6 patients revealed persistent hyperthyroidism. Excluding other causes for evoked hyperthyroidism as common etiological factor psychogenic stress is discussed. It is concluded, that increased thyroid hormone concentration in patients of intensive care units should be controlled within a short time in order to delineate temporary hyperthyroidism against permanent hyperthyroidism.

    Eosinophilic cellulitis (Wells’ syndrome) is an uncommon condition of unknown etiology. Wells’ syndrome is usually seen in adulthood but very rare in childhood. Although pathogenesis of the disease is not very clear, it is a hypersensitivity reaction developing against a variety of exogenous and endogenous antigenic stimuli. Paraphenylenediamine is a strong allergen frequently used as a temporary henna tattoo, which makes the color darker. Here, a 9-year-old male patient with Wells’ syndrome is presented, which developed following a temporary henna tattoo and shown by the patch test sensitivity to paraphenylenediamine. PMID:25395929

    This editorial discusses a report on the 1 year experience with temporary pacing, especially in the emergency setting, in several Norwegian district hospitals. The vast majority of the patients received transvenous temporary pacing, and the majority of leads were placed by noncardiologists....... The procedure times were long and complications were frequent. The organization of emergency pacing is discussed, and we suggest that unless qualified physicians can establish transvenous pacing, the patients who need that should be transferred with transcutaneous pacing as back-up during transport...

    F 18 fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT) is a valuable tool in discriminating malignancy from benign lesion. But because various false positive results reduce the diagnostic specificity, nuclear medicine physicians should be familiar with possible false positive cases. Although many cases of high FDG uptake mimicking malignancy have been reported, temporary intense focal FDG uptake of normal spleen has not been reported previously. We report herein a phenomenon of temporary intense focal FDG uptake of normal spleen without evidence of metastasis in a 46 year old woman with a history of anal cancer.

    From patients of intensive care unit suffering from acute myocardial infarction, decompensated hypertension with left heart insufficiency, severe coronary heart disease, pulmonary infarction, cerebral ischemia 102 were selected with suspicion of hyperthyroidism because of clinical signs. 12 patients fulfilled the criteria of temporary hyperthyroidism, 6 patients revealed persistent hyperthyroidism. Excluding other causes for evoked hyperthyroidism as common etiological factor psychogenic stress is discussed. It is concluded, that increased thyroid hormone concentration in patients of intensive care units should be controlled within a short time in order to delineate temporary hyperthyroidism against permanent hyperthyroidism.

  1. The Liminality of Temporary Agency Work: Exploring the Dimensions of Danish Temporary Agency Workers’ Liminal Experience

    Directory of Open Access Journals (Sweden)

    Ingo Winkler

    2015-03-01

    Full Text Available The concept of liminality refers to the experience to be betwixt-and-between social structures and the associated positions, statuses, and roles. We advance the original use of the concept by introducing the various meanings that the experience of being in a liminal state can take. Drawing on political anthropology we identify the dimensions of ‘types of subjects,’ ‘time,’ ‘space,’ and ‘scale’ in order to analytically unlock the liminal experience. Exemplifying our concept we present the findings from an own study of temporary agency workers in Denmark. Exploring the workers’ interpretations allows us to illustrate to what extent their employment situation constitutes a multi-dimensional liminal experience between established social structures and employment categories. The article emphasizes the complexity of the liminal experience. Theoretically and empirically, we show the many meanings along which liminality can unfold in organizational and work-related contexts. We argue that future studies should explore the various dimensions in other contexts of passages from one relatively stable state to another. In doing so, similarities and differences between various liminal experiences and the role the various dimensions play could be identified.

  7. Temporary worker in the nuclear power industry: an equity analysis

    International Nuclear Information System (INIS)

    Melville, M.H.

    1981-01-01

    There are clear indications based both on the statistical data and on empirical evidence that the employment of large numbers of temporary workers has become a permanent and growing characteristic of the industry. It appears that the size of that work force has been seriously underestimated and that it receives a disproportionate share of the occupational radiation. In order to stay within the limits governing individual exposure in the workplace, the risk has been spread among a larger segment of the population. These facts raise important and ongoing issues of societal and employer responsibility. By the reckonings of this study, the total number of workers employed on a temporary basis by the nuclear power industry is eighteen times greater than those much more narrowly defined by the Nuclear Regulatory Commission (NRC) as transient workers: individuals hired and terminating employment with two or more employers in one quarter. It is estimated that the whole temporary work force numbered about 23,520 in 1976, over a third (35%) of the industry total, and absorbed 47.5% of the total occupational radiation dose. The problems, then, are not inconsiderable: they affect thousands of individuals, a significant segment of the nuclear power industry's work force, members of society who are subjected to a disproportionate burden of radiation risk. Among the conclusions is that it may be necessary to establish special standards, limitations, and records for temporary workers to ensure adequate health protection, follow-up, and care

  19. Temporary Agency Work as a Means of Achieving Flexicurity?

    Directory of Open Access Journals (Sweden)

    Kristina Håkansson

    2012-11-01

    Full Text Available After decades of debate about flexibility, flexicurity has become a new buzzword in working life. Flexicurity refers to both the employer’s demand for flexibility and the employee’s demand for security. Thus, the idea is to solve the flexibility–security trade-off. There is also a discussion that mentions temporary agency work as one way of creating a flexicurity system. The flexibility potential is not called into question—numerical flexibility is a quite common motive for using temporary agency workers. However, the security dimension has to be scrutinized. The aim of this article is to analyze the temporary work agency industry’s potential for providing the security dimensions of the flexicurity model in a Swedish context. The study is based on a survey of whitecollar temporary agency workers in Sweden (n = 533. Overall, the vast majority do not perceive security. Our most important result is that both the work agency and the user firm have a dual impact on the agency workers’ perception of security.

  4. Barriers to fusion

    1999-01-01

    The fusion barrier is formed by the combination of the repulsive Coulomb and attractive nuclear forces. Recent research at the Australian National University has shown that when heavy nuclei collide, instead of a single fusion barrier, there is a set of fusion barriers. These arise due to intrinsic properties of the interacting nuclei such deformation, rotations and vibrations. Thus the range of barrier energies depends on the properties of both nuclei. The transfer of matter between nuclei, forming a neck, can also affect the fusion process. High precision data have been used to determine fusion barrier distributions for many nuclear reactions, leading to new insights into the fusion process

  5. Extremal surface barriers

    International Nuclear Information System (INIS)

    We present a generic condition for Lorentzian manifolds to have a barrier that limits the reach of boundary-anchored extremal surfaces of arbitrary dimension. We show that any surface with nonpositive extrinsic curvature is a barrier, in the sense that extremal surfaces cannot be continuously deformed past it. Furthermore, the outermost barrier surface has nonnegative extrinsic curvature. Under certain conditions, we show that the existence of trapped surfaces implies a barrier, and conversely. In the context of AdS/CFT, these barriers imply that it is impossible to reconstruct the entire bulk using extremal surfaces. We comment on the implications for the firewall controversy

  8. Temporary work and depressive symptoms: a propensity score analysis.

    Science.gov (United States)

    Quesnel-Vallée, Amélie; DeHaney, Suzanne; Ciampi, Antonio

    2010-06-01

    Recent decades have seen a tremendous increase in the complexity of work arrangements, through job sharing, flexible hours, career breaks, compressed work weeks, shift work, reduced job security, and part-time, contract and temporary work. In this study, we focus on one specific group of workers that arguably most embodies non-standard employment, namely temporary workers, and estimate the effect of this type of employment on depressive symptom severity. Accounting for the possibility of mental health selection into temporary work through propensity score analysis, we isolate the direct effects of temporary work on depressive symptoms with varying lags of time since exposure. We use prospective data from the U.S. National Longitudinal Survey of Youth 1979 (NLSY79), which has followed, longitudinally, from 1979 to the present, a nationally representative cohort of American men and women between 14 and 22 years of age in 1979. Three propensity score models were estimated, to capture the effect of different time lags (immediately following exposure, and 2 and 4 years post exposure) between the period of exposure to the outcome. The only significant effects were found among those who had been exposed to temporary work in the two years preceding the outcome measurement. These workers report 1.803 additional depressive symptoms from having experienced this work status (than if they had not been exposed). Moreover, this difference is both statistically and substantively significant, as it represents a 50% increase from the average level of depressive symptoms in this population.

  2. Reconsolidated Salt as a Geotechnical Barrier

    Hansen, Francis D. [Sandia National Lab. (SNL-NM), Albuquerque, NM (United States); Gadbury, Casey [USDOE Carlsbad Field Office, NM (United States)

    2015-11-01

    Salt as a geologic medium has several attributes favorable to long-term isolation of waste placed in mined openings. Salt formations are largely impermeable and induced fractures heal as stress returns to equilibrium. Permanent isolation also depends upon the ability to construct geotechnical barriers that achieve nearly the same high-performance characteristics attributed to the native salt formation. Salt repository seal concepts often include elements of reconstituted granular salt. As a specific case in point, the Waste Isolation Pilot Plant recently received regulatory approval to change the disposal panel closure design from an engineered barrier constructed of a salt-based concrete to one that employs simple run-of-mine salt and temporary bulkheads for isolation from ventilation. The Waste Isolation Pilot Plant is a radioactive waste disposal repository for defense-related transuranic elements mined from the Permian evaporite salt beds in southeast New Mexico. Its approved shaft seal design incorporates barrier components comprising salt-based concrete, bentonite, and substantial depths of crushed salt compacted to enhance reconsolidation. This paper will focus on crushed salt behavior when applied as drift closures to isolate disposal rooms during operations. Scientific aspects of salt reconsolidation have been studied extensively. The technical basis for geotechnical barrier performance has been strengthened by recent experimental findings and analogue comparisons. The panel closure change was accompanied by recognition that granular salt will return to a physical state similar to the halite surrounding it. Use of run-of-mine salt ensures physical and chemical compatibility with the repository environment and simplifies ongoing disposal operations. Our current knowledge and expected outcome of research can be assimilated with lessons learned to put forward designs and operational concepts for the next generation of salt repositories.

As a specific case in point, the Waste Isolation Pilot Plant recently received regulatory approval to change the disposal panel closure design from an engineered barrier constructed of a salt-based concrete to one that employs simple run-of-mine salt and temporary bulkheads for isolation from ventilation. The Waste Isolation Pilot Plant is a radioactive waste disposal repository for defense-related transuranic elements mined from the Permian evaporite salt beds in southeast New Mexico. Its approved shaft seal design incorporates barrier components comprising salt-based concrete, bentonite, and substantial depths of crushed salt compacted to enhance reconsolidation. This paper will focus on crushed salt behavior when applied as drift closures to isolate disposal rooms during operations. Scientific aspects of salt reconsolidation have been studied extensively. The technical basis for geotechnical barrier performance has been strengthened by recent experimental findings and analogue comparisons. The panel closure change was accompanied by recognition that granular salt will return to a physical state similar to the halite surrounding it. Use of run-of-mine salt ensures physical and chemical compatibility with the repository environment and simplifies ongoing disposal operations. Our current knowledge and expected outcome of research can be assimilated with lessons learned to put forward designs and operational concepts for the next generation of salt repositories.

    Full Text Available Temporary agency workers are coming under non-standard employments, who have temporary attachment to the working organization. With dynamic business environment and flexible work arrangements, temporary agency employments are also emerged in Sri Lanka. Temporary agency workers are dual committed employees. However, with this dual commitment, organizations face issues in achieving temporary agency workers’ commitment due to low attention of agencies to temporary agency workers. Even though the Client organization provides due attention to temporary agency workers, they fail to receive due commitment due to the lack of attention from agency to temporary agency workers. This study was conducted to identify the agency related factors affecting temporary agency workers’ commitment. This was carried out as a cross sectional field study with a sample of 93 workers from temporary agency works in the ABC (pvt ltd. 93 temporary agency workers were selected as sample. Data were collected via a standard questionnaire that met accepted standards of validity and reliability. Descriptive statistics, Simple ranking, Factor analysis, ANOVA and Independent Sample T-Test technique were performed to analyze data. No of Temporary workers to supervisor (temp to consult ratio is the most influencing factor of temporary agency workers’ commitment in agency context. Job satisfaction, agency support, side bets, interactional justice, lack of alternative employments, procedural justice, distributive justice, reciprocity norm acceptance, socialization, breach of psychological contract, lack of skill transferability are the other factors, which are ordered from most influencing factor to less affecting factor to workers’ organizational commitment . Findings revealed that eleven out of thirteen factors are job related factors, other two are organization related and person related factors. Most client companies provide their attention, while agencies fail to provide

    Marriage is a risky undertaking that people enter with incomplete information about their partner and their future life circumstances. A large literature has shown how new information gained from unforeseen but long-lasting or permanent changes in life circumstances may trigger a divorce. We extend this literature by considering how information gained from a temporary change in life circumstances-in our case, a couple having a child with infantile colic-may affect divorce behavior. Although persistent life changes are known to induce divorce, we argue that a temporary stressful situation allows couples more quickly to discern the quality of their relationship, in some cases leading them to divorce sooner than they otherwise would have. We formalize this argument in a model of Bayesian updating and test it using data from Denmark. We find that the incidence of infantile colic shortens the time to divorce or disruption among couples who would have split up anyway.

    Pacific Gas and Electric (PG and E) Company's Diablo Canyon Power Plant (DCPP), which is located on California's central coast, has access to three sources of raw water: creek water, well water, and seawater. Creek and well water are DCPP's primary sources of raw water; however, because their supply is limited, these sources are supplemented with seawater. The purpose of this paper is to discuss the temporary, rental, reverse osmosis systems used by PG and E to process DCPP's raw water into water suitable for plant makeup. This paper addresses the following issues: the selection of reverse osmosis over alternative water processing technologies; the decision to use vendor-operated temporary, rental, reverse osmosis equipment versus permanent PG and E-owned and -operated equipment; the performance of DCPP's rental reverse osmosis systems; and, the lessons learned from DCPP's reverse osmosis system rental experience that might be useful to other plants considering renting similar equipment

    We discuss the creation of transport barriers in magnetically confined plasmas with non monotonic equilibrium radial profiles. These barriers reduce the transport in the shearless region (i.e., where the twist condition does not hold). For the chaotic motion of particles in an equilibrium electric field with a nonmonotonic radial profile, perturbed by electrostatic waves, we show that a nontwist transport barrier can be created in the plasma by modifying the electric field radial profile. We also show non twist barriers in chaotic magnetic field line transport in the plasma near to the tokamak wall with resonant modes due to electric currents in external coils.

    2017-08-01

    Knowledge of the spatial distribution of temporary and perennial river channels in a whole catchment is important for effective integrated basin management and river biodiversity conservation. However, this information is usually not available or is incomplete. In this study, we present a statistically based methodology to classify river segments from a whole river network (Deva-Cares catchment, Northern Spain) as temporary or perennial. This method is based on an a priori classification of a subset of river segments as temporary or perennial, using field surveys and aerial images, and then running Random Forest models to predict classification membership for the rest of the river network. The independent variables and the river network were derived following a computer-based geospatial simulation of riverine landscapes. The model results show high values of overall accuracy, sensitivity, and specificity for the evaluation of the fitted model to the training and testing data set (≥0.9). The most important independent variables were catchment area, area occupied by broadleaf forest, minimum monthly precipitation in August, and average catchment elevation. The final map shows 7525 temporary river segments (1012.5 km) and 3731 perennial river segments (662.5 km). A subsequent validation of the mapping results using River Habitat Survey data and expert knowledge supported the validity of the proposed maps. We conclude that the proposed methodology is a valid method for mapping the limits of flow permanence that could substantially increase our understanding of the spatial links between terrestrial and aquatic interfaces, improving the research, management, and conservation of river biodiversity and functioning.

    Full Text Available Temporary housing plays an important role in providing secure, hygienic, private, and comfortable shelter in the aftermath of disaster (such as flood, fire, earthquake, etc.. Additionally, temporary housing can also be used as a sustainable form of on-site residences for construction workers. While most of the building components used in temporary housing can be manufactured in a plant, prefabrication technology improves the production efficiency of temporary housing; furthermore, integrated renewable energy systems, for example, solar photovoltaic (PV system, offer benefits for temporary housing operations. In order to assess the environmental impacts of prefabricated temporary housing equipped with renewable energy systems, this study first divides the life cycle of temporary housing into six stages, and then establishes a life cycle assessment (LCA model for each stage. Furthermore, with the aim of reducing the environmental impacts, life cycle carbon reduction measures are proposed for each stage of temporary housing. The proposed methodology is demonstrated using a case study in China. Based on the proposed carbon reduction measures, the LCA of a prefabricated temporary housing case study building equipped with renewable energy systems indicates a carbon emissions intensity of 35.7 kg/m2·per year, as well as a reduction in material embodied emissions of 18%, assembly emissions of 17.5%, and operational emissions of 91.5%. This research proposes a carbon reduction-driven LCA of temporary housing and contributes to promoting sustainable development of prefabricated temporary housing equipped with renewable energy systems.

  15. Inference about density and temporary emigration in unmarked populations

    2011-01-01

    Few species are distributed uniformly in space, and populations of mobile organisms are rarely closed with respect to movement, yet many models of density rely upon these assumptions. We present a hierarchical model allowing inference about the density of unmarked populations subject to temporary emigration and imperfect detection. The model can be fit to data collected using a variety of standard survey methods such as repeated point counts in which removal sampling, double-observer sampling, or distance sampling is used during each count. Simulation studies demonstrated that parameter estimators are unbiased when temporary emigration is either "completely random" or is determined by the size and location of home ranges relative to survey points. We also applied the model to repeated removal sampling data collected on Chestnut-sided Warblers (Dendroica pensylvancia) in the White Mountain National Forest, USA. The density estimate from our model, 1.09 birds/ha, was similar to an estimate of 1.11 birds/ha produced by an intensive spot-mapping effort. Our model is also applicable when processes other than temporary emigration affect the probability of being available for detection, such as in studies using cue counts. Functions to implement the model have been added to the R package unmarked.

  16. The Diaspora and Temporary Migrant Workers: Basic Concepts

    Directory of Open Access Journals (Sweden)

    Marija Krstić

    2016-02-01

    Full Text Available The paper looks at the phenomenon of migrant workers who emigrated to Western European countries after World War II. The labor demands created by the economic reconstruction of these countries, most notably Great Britain, West Germany, France, Switzerland, the Benelux countries, Sweden and Austria, coupled with low birth rates and high death rates, made it necessary for them to hire immigrant workers. On the other hand, poor economic conditions, few employment opportunities and a yearning for a higher standard of living drove workers from Italy, Spain, Portugal, Turkey, Yugoslavia, Greece, Ireland, Finland and North Africa to seek work abroad. These temporary migrant workers represent a link between their countries of origin and their host countries, and, as a group of people maintaining links with their native countries, they can also be considered their countries’ diaspora. However, considering the temporary nature of their residence abroad, it is questionable whether they actually are a diaspora. It is for this reason that the paper juxtaposes the phenomena of the diaspora and temporary migrant workers in order to analyze the question of whether, when and how these workers become a diaspora. In particular, it focuses on migrant workers from Yugoslavia, usually referred to as “gastarbajteri” (gastarbeiter, who in the 1960s and 1970s migrated mostly to West Germany, Austria, Australia, France and Switzerland, and on their political treatment by the Yugoslav state.

  17. Temporary vs. Permanent Sub-slab Ports: A Comparative ...

    Science.gov (United States)

    Vapor intrusion (VI) is the migration of subsurface vapors, including radon and volatile organic compounds (VOCs), from the subsurface to indoor air. The VI exposure pathway extends from the contaminant source, which can be impacted soil, non-aqueous phase liquid, or contaminated groundwater, to indoor air-exposure points. Therefore, contaminated matrices may include groundwater, soil, soil gas, and indoor air. VOC contaminants of concern typically include halogenated solvents such as trichloroethene, tetrachloroethene, and chloroform, as well as petroleum hydrocarbons, such as the aromatic VOCs benzene, toluene, and xylenes. Radon is a colorless radioactive gas that is released by radioactive decay of radionuclides in rock and soil that migrate into homes through VI in a similar fashion to VOCs. This project focused on the performance of permanent versus temporary sub-slab sampling ports for the determination of VI of halogenated VOCs and radon into an unoccupied house. VOC and radon concentrations measured simultaneously in soil gas using collocated temporary and permanent ports appeared to be independent of the type of port. The variability between collocated temporary and permanent ports was much less than the spatial variability between different locations within a single residential duplex. The agreement of the majority of VOC and radon concentrations, 0–36% relative percent difference, and 2–19% relative standard deviation respectively, of each sub-sl

    Moline, G.R.

    1999-01-01

    The Homogeneous Reactor Experiment (HRE) Pond is the site of a former impoundment for radioactive wastes on the Oak Ridge Reservation (ORR) in east Tennessee. The pond received radioactive wastes from 1957 to 1962, and was subsequently drained, filled with soil, and covered with an asphalt cap. The site is bordered to the east and south by an unnamed stream that contains significant concentrations of radioactive contaminants, primarily 90 Sr. Because of the proximity of the stream to the HRE disposal site and the probable flow of groundwater from the site to the stream, it was hypothesized that the HRE Pond has been a source of contamination to the creek. The HRE-Pond was chosen as the site of a cryogenic barrier demonstration to evaluate this technology as a means for rapid, temporary isolation of contaminants in the type of subsurface environment that exists on the ORR. The cryogenic barrier is created by the circulation of liquid CO 2 through a system of thermoprobes installed in boreholes which are backfilled with sand. The probes cool the subsurface, creating a vertical ice wall by freezing adjacent groundwater, effectively surrounding the pond on four sides. The purpose of this investigation was to evaluate the hydrologic conditions within and around the pond prior to, during, and after the cryogenic barrier emplacement. The objectives were (1) to provide a hydrologic baseline for post-banner performance assessment, (2) to confirm that the pond is hydraulically connected to the surrounding sediments, (3) to determine the likely contaminant exit pathways from the pond, and (4) to measure changes in hydrologic conditions after barrier emplacement in order to assess the barrier performance. Because relatively little information about the subsurface hydrology and the actual configuration of the pond existed, data from multiple sources was required to reconstruct this complex system

    The Administrator of the Drug Enforcement Administration is issuing this temporary scheduling order to schedule the synthetic opioids, N-(2-fluorophenyl)-N-(1-phenethylpiperidin-4-yl)propionamide (ortho-fluorofentanyl or 2-fluorofentanyl), N-(1-phenethylpiperidin-4-yl)-N-phenyltetrahydrofuran-2-carboxamide (tetrahydrofuranyl fentanyl), and 2-methoxy-N-(1-phenethylpiperidin-4-yl)-N-phenylacetamide (methoxyacetyl fentanyl), into Schedule I. This action is based on a finding by the Administrator that the placement of ortho-fluorofentanyl, tetrahydrofuranyl fentanyl, and methoxyacetyl fentanyl into Schedule I of the Controlled Substances Act is necessary to avoid an imminent hazard to the public safety. As a result of this order, the regulatory controls and administrative, civil, and criminal sanctions applicable to Schedule I controlled substances will be imposed on persons who handle (manufacture, distribute, reverse distribute, import, export, engage in research, conduct instructional activities or chemical analysis, or possess), or propose to handle, ortho-fluorofentanyl, tetrahydrofuranyl fentanyl, and methoxyacetyl fentanyl.

    The ground vehicle is one of the most effective tools available to an adversary force. Vehicles can be used to penetrate many types of perimeter barriers, transport equipment and personnel rapidly over long distances, and deliver large amounts of explosives directly to facilities in suicide missions. The function of a vehicle barrier system is to detain or disable a defined threat vehicle at a selected distance from a protected facility. Numerous facilities are installing, or planning to install, vehicle barrier systems and many of these facilities are requesting guidance to do so adequately. Therefore, vehicle barriers are being evaluated to determine their stopping capabilities so that systems can be designed that are both balanced and capable of providing a desired degree of protection. Equally important, many of the considerations that should be taken into account when establishing a vehicle barrier system have been identified. These considerations which pertain to site preparation, barrier selection, system integration and operation, and vehicle/barrier interaction, are discussed in this paper

    This study examines stakeholders' perspectives on the health and well-being of temporary foreign workers (TFWs) and their families in Alberta, Canada. We used a critically informed qualitative methodology. We interviewed 13 stakeholders, including service providers and policy makers. Stakeholders involved in providing services to TFWs perceived that the workers experience (1) barriers in accessing mental health services, (2) mental health challenges, (3) family health challenges, (4) occupational health challenges, and (5) income and social status as a social determinant of health. Immigration and class status intersect to influence the health of this vulnerable population in Canada.

    2014-02-01

    Although in the case of subdural collections temporary shunting has been suggested as a viable alternative for definitive drainage of the accumulated fluid until restoration of the normal CSF dynamics, there is no agreement on the best management strategy for pseudomeningocele. The authors performed a retrospective chart review in order to evaluate the clinical outcomes of infants temporarily shunted for pseudomeningocele without encephalocele at our institution (The University of Illinois at Peoria/Illinois Neurological Institute) in the period from 2004 to 2012. The epidemiological characteristics, clinical management, and final outcomes of such subpopulation were compared with a control group which received temporary shunting for subdural hematomas (SDH) during the same period. Four patients (100% male) ranging in age from 8.9 to 27.1 months (mean = 13.88) with pseudomeningocele and 17 patients (64.7% male) ranging in age from 1.9 to 11.8 months (mean = 4.15) with SDH were identified. Although the initial management included sequential percutaneous subdural tapping in 82% of the patients, all children ultimately failed such strategy, requiring either subdural-peritoneal (81% of the cases) or subgaleal-peritoneal (19% of the cases) shunting. The mean implant duration was 201 days for the pseudomeningocele group and 384 days for the SDH one. Mean post-shunt hospitalization was 2 days for patients with pseudomeningocele and 4 days for patients with SDH. There was no statistical difference in terms of complications, length of hospitalization post-shunting, or clinical outcomes between the patients with pseudomeningocele and those with SDH. Temporary shunting of infants with pseudo-meningocele constitutes a viable therapeutic alternative with favorable clinical outcomes and a low risk of shunt dependency similar to those of children with SDH.

  8. Permanent Temporariness? Changes in Social Contracts in Knowledge Work

    Directory of Open Access Journals (Sweden)

    Bente Rasmussen

    2012-02-01

    Full Text Available Many sociologists have argued that work no longer plays the central role in contemporary life experience because we have entered an age of insecurity in relation to employment, and knowledge workers are often pictured as egoistical portfolio workers who are only interested in their careers and no longer loyal to their employers. Cappelli (1999 on the other hand argues that more insecure employment relations is a result of employers’ strategy to buy workers rather than offering them long-term relations. Using case studies from seven different knowledge work contexts in Norway, this article argues that more temporary employment relations is not the result of career-seeking portfolio workers, but of changes in employment practices of their employers. These are not primarily changes in the formal employment contracts from permanent to temporary employment, but in the social contracts as they are practiced by the employers and experienced by the knowledge workers in the different contexts of knowledge work. The reason for more temporary relations was not because work does not matter for knowledge workers. On the contrary, we found that they accepted insecure conditions because work mattered and because they were eager to take on new tasks, learn the trade in new fields, and show that they were able to do the job. When they left their employer, it was because they were not able to do a good job in their positions or because they were increasingly directly exposed to an insecure market that signaled that they were not profitable (enough for their employer. Although changes in employment practices by the employers toward more short-term relations are not caused by disloyal portfolio workers, these practices may produce the problem of disloyal workers who have to secure their employment in the labor market.

    Acceptance of nuclear materials into a monitoring regime is complicated if the materials are in classified shapes or have classified composition. An attribute measurement system with an information barrier can be emplo,yed to generate an unclassified display from classified measurements. This information barrier must meet two criteria: (1) classified information cannot be released to the monitoring party, and (2) the monitoring party must be convinced that the unclassified output accurately represents the classified input. Criterion 1 is critical to the host country to protect the classified information. Criterion 2 is critical to the monitoring party and is often termed the 'authentication problem.' Thus, the necessity for authentication of a measurement system with an information barrier stems directly from the description of a useful information barrier. Authentication issues must be continually addressed during the entire development lifecycle of the measurement system as opposed to being applied only after the system is built.

    Wing, N.R.; Gee, G.W.

    1990-01-01

    Protective barrier and warning marker systems are being developed to isolate wastes disposed of near the earth's surface at the Hanford Site. The barrier is designed to function in an arid to semiarid climate, to limit infiltration and percolation of water through the waste zone to near-zero, to be maintenance free, and to last up to 10,000 yr. Natural materials (e.g., fine soil, sand, gravel, riprap, clay, asphalt) have been selected to optimize barrier performance and longevity and to create an integrated structure with redundant features. These materials isolate wastes by limiting water drainage; reducing the likelihood of plant, animal, and human intrusion; controlling emission of noxious gases; and minimizing erosion. Westinghouse Hanford Company and Pacific Northwest Laboratory efforts to assess the performance of various barrier and marker designs will be discussed

  15. Engineered barriers: current status

    Atkinson, A.; Marsh, G.P.

    1988-01-01

    This report summarises the current state of research relevant to assessing the performance of engineered barriers made of steel and concrete in radioactive waste repositories. The objective of these barriers is to contain the radionuclides within them by providing both physical and chemical impediment to their release. The physical barriers are of most value for highly soluble isotopes with relatively short half-lives (eg 137 Cs), since they can provide containment until a large fraction of the activity has decayed. In addition they can facilitate retrievability for some period after disposal. The chemical barriers operate by beneficial conditioning of the near field groundwater and providing sites for sorption of radionuclides. Both of these reduce the aqueous concentration of radionuclides in the near field. (author)

    2018-02-07

    Safe storage of guns outside the household while someone is at risk for suicide is important for suicide prevention. Some gun retailers offer temporary firearm storage as a community resource. Others may be willing if perceived barriers can be addressed. We invited all gun retailers in eight Mountain West states to respond to a questionnaire about the barriers they perceive in offering temporary, voluntary gun storage for community members. Ninety-five retailers responded (25% response rate). Fifty-eight percent believed federal laws make it harder to store guns and 25% perceived state laws to be obstacles. Over 60% cited legal liability in storing and returning guns as barriers. Other important barriers included cost, space and logistical issues of drop off and pick up. Strategies to reduce legal and other barriers will need to be addressed to better engage gun retailers as a community resource for safe gun storage. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

  1. Defining chemical status of a temporary Mediterranean River.

    Skoulikidis, Nikolaos Th

    2008-07-01

    Although the majority of rivers and streams in the Mediterranean area are temporary, no particular attention is being paid for such systems in the Water Framework Directive (WFD). A typical temporal Mediterranean river, draining an intensively cultivated basin, was assessed for its chemical status. Elevated concentrations of nitrates and salts in river water as well as nutrients and heavy metals in river sediments have been attributed to agricultural land uses and practices and point sources of organic pollution. A scheme for the classification of the river's chemical status (within the ecological quality classification procedure) was applied by combining pollution parameters in groups according to related pressures. In light of the temporal hydrological regime and anthropogenic impacts, sediment chemical quality elements were considered, in addition to hydrochemical ones. Despite the extensive agricultural activities in the basin, the majority of the sites examined showed a good quality and only three of them were classified as moderate. For the classification of the chemical quality of temporary water bodies, there is a need to develop ecologically relevant salinity and sediment quality standards.

    Full Text Available A greenhouse study to evaluate adaptation of 4 herbaceous summer legumes to temporary waterlogging was conducted.  Species evaluated were Desmanthus virgatus and Aeschynomene americana in their vegetative stage, and Macroptilium lathyroides and M. atropurpureum in both vegetative and reproductive stages.  The experimental design was randomized blocks with 5 replications and treatments were:  T0, control; T1, saturation by capillary movement placing pots in buckets of 5 L with 10 cm of permanent water; and T2, flooding, placing pots in buckets of 10 L and a layer of water 5 cm above the soil.  The duration of the water treatments was 7 days. Waterlogging did not affect shoot or root biomass production nor nodulation in A. americana, whereas D. virgatus had its highest dry matter production in saturated soil (T1.  In M. lathyroides flooding tolerance was more evident in the reproductive than in the vegetative stage, probably due to more production of adventitious roots and formation of aerenchymatic tissue.  Macroptilium atropurpureum showed adaptation to temporary flooding.  Survival and quick recovery of these species would confirm their potential as forages for temporarily waterlogged soils.Keywords: Forage legumes, flooding, Aeschynomene americana, Desmanthus virgatus, Macroptilium lathyroides, Northeast Argentina.DOI: 10.17138/TGFT(2278-286

  3. The profound precariousness of work through temporary work agency

    Directory of Open Access Journals (Sweden)

    2016-12-01

    Full Text Available The increase in the number of atypical work contracts in the field of industry relationships, as part of a major European trend towards gaining more flexibility in the labour market, is significant and cannot be overlooked in most member countries of the European Union. This finding is corroborated by the recent surveys conducted across Europe, that reveal the prevalence of these flexible ways of organizing work, over the archetypal template of the individual work contract. However, this range of atypical contractual arrangements and the great number of versions and subcategories they include, are describing a number of negative features that seem to characterize these new forms of employment. Since the field of atypical employment is complex and we cannot analyse the incidence of these negative effects for all the atypical methods of employment, in the following article we will limit ourselves to explore the pressing issues related to the system of temporary work through work agencies. As we shall see, all aspects of the salary field, of health and safety at work and the level of insecurity and instability of labour through temporary work agency reveals a strong character associated with this kind of precarious employment.

  4. Temporary endoscopic metallic stent for idiopathic esophageal achalasia.

    Science.gov (United States)

    Coppola, Franco; Gaia, Silvia; Rolle, Emanuela; Recchia, Serafino

    2014-02-01

    Idiopathic achalasia is a motor disorder of the esophagus of unknown etiology caused by loss of motor neurons determining an altered motility. It may determine severe symptoms such as progressive dysphagia, regurgitations, and pulmonary aspirations. Many therapeutic options may be offered to patients with achalasia, from surgery to endoscopic treatments such as pneumatic dilation, botulinum injection, peroral endoscopic myotomy, or endoscopic stenting. Recently, temporary placement of a stent was proposed by Cheng as therapy for achalasia disorders, whereas no Western authors have dealt with it up to date. The present study reports our preliminary experience in 7 patients with achalasia treated with a temporary stent. Partially covered self-expanding metallic stents (Micro-Tech, Nanjin, China) 80 mm long and 30 mm wide were placed under fluoroscopic control and removed after 6 days. Clinical follow-up was scheduled to check endoscopic success, symptoms release, and complications. The placement and the removal of the stents were obtained in all patients without complications. Mean clinical follow-up was 19 months. Five out of 7 patients referred total symptoms release and 2 experienced significant improvement of dysphagia. The procedure was not time consuming and was safe; no mild or severe complications were registered. In conclusion, our results may suggest a possible safe and effective endoscopic alternative treatment in patients with achalasia; however, further larger studies are necessary to confirm these promising, but very preliminary, data.

    In many countries, including South Korea, labour market changes have led to an increase in unstable, temporary jobs. There is evidence that workers in such jobs may experience poorer mental health than those in more stable employment. To investigate the association between temporary employment and depressive symptoms in South Korean workers. We analysed data from the 2010-2014 Korean Welfare Panel Study (KOWEPS). Employment type was categorized into workers paid per day of labour (day labourers), those on short-term contracts (fixed-term workers) and permanent workers. The association between employment type and depressive symptoms, measured using the Center for Epidemiological Studies Depression scale (CES-D 11), was examined using the generalized estimating equation model. A total of 3756 workers aged 20-59 were included in the 2010 baseline population. Day labourers had the highest mean CES-D 11 score, followed by fixed-term workers and permanent workers. With the day labourer group as reference, fixed-term workers (β: -1.5027, P < 0.001) and permanent workers (β: -2.1848, P < 0.001) showed statistically significant decreases in depression scores. Compared with day labourers, fixed-term workers and permanent workers had progressively lower depression scores. The findings of this study suggest that mental health inequalities based on employment type exist in South Korea. © The Author 2017.

  6. Estimating temporary emigration and breeding proportions using capture-recapture data with Pollock's robust design

    Science.gov (United States)

    Kendall, W.L.; Nichols, J.D.; Hines, J.E.

    1997-01-01

    Statistical inference for capture-recapture studies of open animal populations typically relies on the assumption that all emigration from the studied population is permanent. However, there are many instances in which this assumption is unlikely to be met. We define two general models for the process of temporary emigration, completely random and Markovian. We then consider effects of these two types of temporary emigration on Jolly-Seber (Seber 1982) estimators and on estimators arising from the full-likelihood approach of Kendall et al. (1995) to robust design data. Capture-recapture data arising from Pollock's (1982) robust design provide the basis for obtaining unbiased estimates of demographic parameters in the presence of temporary emigration and for estimating the probability of temporary emigration. We present a likelihood-based approach to dealing with temporary emigration that permits estimation under different models of temporary emigration and yields tests for completely random and Markovian emigration. In addition, we use the relationship between capture probability estimates based on closed and open models under completely random temporary emigration to derive three ad hoc estimators for the probability of temporary emigration, two of which should be especially useful in situations where capture probabilities are heterogeneous among individual animals. Ad hoc and full-likelihood estimators are illustrated for small mammal capture-recapture data sets. We believe that these models and estimators will be useful for testing hypotheses about the process of temporary emigration, for estimating demographic parameters in the presence of temporary emigration, and for estimating probabilities of temporary emigration. These latter estimates are frequently of ecological interest as indicators of animal movement and, in some sampling situations, as direct estimates of breeding probabilities and proportions.

  7. Fuzzy barrier distributions

    International Nuclear Information System (INIS)

    Piasecki, E.

    2009-01-01

    Heavy-ion collisions often produce a fusion barrier distribution with structures displaying a fingerprint of couplings to highly collective excitations [1]. Basically the same distribution can be obtained from large-angle quasi-elastic scattering, though here the role of the many weak direct-reaction channels is unclear. For 2 0N e + 9 0Z r we have observed the barrier structures expected for the highly deformed neon projectile, but for 2 0N e + 9 2Z r we find completely smooth distribution (see Fig.1). We find that transfer channels in these systems are of similar strength but single particle excitations are significantly stronger in the latter case. They apparently reduce the 'resolving power' of the quasi-elastic channel, what leads to smeared out, or 'fuzzy' barrier distribution. This is the first case when such a phenomenon has been observed.(author)

  8. Health Barriers to Learning

    Directory of Open Access Journals (Sweden)

    Delaney Gracy

    2014-01-01

    Full Text Available This article summarizes the results from a 2013 online survey with 408 principals and assistant principals in New York City public elementary and middle schools. The survey assessed three primary areas: health issues in the school, health issues perceived as barriers to learning for affected students, and resources needed to address these barriers. Eighteen of the 22 health conditions listed in the survey were considered a moderate or serious issue within their schools by at least 10% of respondents. All 22 of the health issues were perceived as a barrier to learning by between 12% and 87% of the respondents. Representatives from schools that serve a higher percentage of low-income students reported significantly higher levels of concern about the extent of health issues and their impact on learning. Respondents most often said they need linkages with organizations that can provide additional services and resources at the school, especially for mental health.

  9. Tips for the fabrication of temporary tritium experiments

    International Nuclear Information System (INIS)

    Binning, K.E.; Jenkins, E.M.

    1988-01-01

    The Tritium System Test Assembly (TSTA) is a facility built for the demonstration of tritium handling systems necessary for tritium-burning fusion reactors. The facility has been in operation handling tritium for four years. The current inventory of tritium is approximately one hundred grams, with DOE approval for a maximum inventory of two hundred grams. Not all experiments performed at TSTA require the operation of the main process loop. During the last four years, many small scale experiments have been performed to test the compatibility and operation of tritium processing components in small self-contained experimental packages. These packages are fabricated inside secondary containment gloveboxes and can be operated for hours or months with little monitoring. Construction of these packages need to be tritium compatible, inexpensive, easy to build, and versatile. This paper discusses some of the problems and remedies encountered during the building of temporary experiments

  10. Temporary threshold shift after exposure to pop music.

    Science.gov (United States)

    Axelsson, A; Lindgren, F

    1978-01-01

    Temporary threshold shift (TTS) was studied in pop musicians as well as in listeners. It appears that TTS is less pronounced in pop musicians than in listeners. This can only in part be explained by slightly inferior hearing threshold levels than in the audience before exposure. Further, male listeners showed more TTS than female listeners. After 2 hours of exposure to live pop music a TTS2 appears in pop musicians after an exposure to 98 dB(A) as opposed to listeners where TTS2 appears at 92 dB(A). When the present results are related to the CHABA risk criteria it seems that exposure to live pop music at 100 dB(A) for 2 hours is a limit which should not be exceeded if the risk of permanent hearing loss is to be avoided.

    Background A project is a temporary endeavour undertaken to create a product or service. Projects are frequently used for the testing and development of new approaches in social work. Projects can receive grants from central, often national or international institutions, and allow for more...... experimentation than work placed within existing institutions. Discussion For socially marginalized groups who need continuing support and care, receiving help in a project means that the clients will have to be transferred to other services when the project ends. There is also a risk that clients will experience...... a decline in services, as staff members have to seek new employment towards the end of the project, or begin to focus more on the evaluation than the services. This raises some ethical issues concerning the use of human subjects in projects. Conclusion Project managers should consider ethical issues...

  12. Digital lingual orthodontics and temporary anchorage devices for efficient biomechanics

    2016-01-01

    Full Text Available Adult patients seeking orthodontic treatment at all times present with an esthetic demand even during treatment. The lingual orthodontics, apart from its esthetic values, also presents several other advantages. Currently, it has become a complete system in itself, starting from an accurate diagnosis, treatment protocol, and laboratory procedure to placement of the appliance in the patient′s mouth. With the advent of computer-aided design/computer-aided manufacturing system, the lingual orthodontics is more evolved and made ease operators in respect to more efficient mechanics and reduced archwire adjustments. The present article presents two cases to show the efficiency of lingual orthodontics with temporary anchorage devices and anterior retraction hook.

Several contributions result: First, I challenge our expectation that a short shadow of the future will decrease the likelihood of cooperation by demonstrating how the clan-like tendency to construct common values and aspirations motivated...... cooperative behavior in these groups. Second, I challenge our expectation that a task-oriented over relationship-oriented approach will inevitably dominate work when projects are time-bound and of short duration by describing moments in which these groups chose relationship-oriented activities despite time...

  14. Temporary and circular labour migration and codevelpment: a case estudy

    Directory of Open Access Journals (Sweden)

    Elena Sánchez-Montijano

    2012-05-01

    Full Text Available The search for new ways to manage international migration is one of the main topics at the current political agendas. Within this framework, Temporary and Circular Labour Migration (TCLM as a way of fl ow management on the one hand, and co-development as a set of actions that seek to articulate migration and development on the other, have recently been promoted as double win situations. Both initiatives depart from the assumption that migrants can make important contributions to development, in their countries of destination but also in their countries of origin. The paper explores the opportunities and difficulties that arise when a single initiative attempts tobring together these two types of activities, which have so far been managed by different entities and in separated venues. The study raises the question about the positive and negative effects of this alliance. The article presents the results of a TCLM case study.

    Directory of Open Access Journals (Sweden)

    2008-07-01

    Full Text Available Abstract Introduction Various surgical procedures are available to correct paralytic ectropion, which are applied in irreversible facial paresis. Problems occur when facial paresis has an unclear prognosis, since surgery of the lower eyelid is usually irreversible. We propose a simple method to correct temporary ectropion in facial palsy by applying an adhesive strip. Patients and methods Ten patients with peripheral facial paresis and paralytic ectropion were treated with an adhesive strip to correct paralytic ectropion. We used "Steri-Strips" (45 × 6.0 mm, which were taped on the carefully cleaned skin of the lower eyelid and of the adjacent zygomatic region until the prognosis of the paresis was clarified. In addition to the examiner's evaluation of the lower lacrimal point in the lacrimal lake, subjective improvement of the symptoms was assessed using a visual analogue scale (VAS, 1–10. Results 9 patients reported a clear improvement of the symptoms after adhesive taping. There was a clear regression of tearing (VAS (median = 8; 1 = no improvement, 10 = very good improvement, the cosmetic impairment of the adhesive tape was low (VAS (median = 2.5; 1 = no impairment, 10 = severe impairment and most of the patients found the use of the adhesive strip helpful. There was slight reddening of the skin in one case and well tolerated by the facial skin in the other cases. Conclusion The cause and location of facial nerve damage are decisive for the type of surgical therapy. In potentially reversible facial paresis, procedures should be used that are easily performed and above all reversible without complications. Until a reliable prognosis of the paresis can be made, adhesive taping is suited for the temporary treatment of paralytic ectropion. Adhesive taping is simple and can be performed by the patient.

So on considered in given work irradiated model no condition on descending in not put. Model consists of gaussian chains with (N x m) numbers (from them N - a number of chains and m - a number an beads on chains, which are distinguished one from another by the degree a mobility) potential interaction centres with the surround environment. The interaction carries of inter and intramolecular nature , including and hydrogen bond. Between these centres there are constant and casual contacts. For terminal volume and terminal time possible to neglect influences casual bonds of fluctuation.Let number of constant contacts is equally n. Changing of number of contacts under the action of irradiating carries a kinetic nature and so it is described by the differential equation, which parameters are formation frequencies and destroying the contacts. Decision of this equation allows to calculate a complex module of bounce, on which possible judge on velocities of relaxation process irradiated polymer. At the equality unit a relations of frequencies of formation and destroying of the contact occurs as it were a dynamic balance and spectrum temporary relaxations corresponds a spectrum non radiating models. An accumulation of energy occurs under small energy of irradiating in the in that nodes, which encircled smaller number nodes. So small doses of irradiating a polymer show a wing of spectrum temporary to relaxations in the lion. Comparison of obtained formula with available in literature by data has shown that frequency of forming the contacts much less, than their destruction frequency

  18. TREHS (Temporary Rivers Ecological and Hydrological Status): new software for investigating the degree of hydrologic alteration of temporary streams.

    The evaluation of the hydrological alteration of a stream due to human activities is a first step to assess its overall quality and to design management strategies for its potential restoration. This task is currently made comparing impacted against unimpacted hydrographs, with the help of software tools, such as the IHA (Indicators of Hydrologic Alteration). Then, the environmental evaluation of the hydrological alteration is to be made in terms of its expectable menace for the original biological communities and/or its help for the spread of invasive species. However, when the regime of the target stream is not perennial, there are four main difficulties for implementing methods for assessing hydrological alteration: i) the main hydrological features relevant for biological communities in a temporary stream are not quantitative (discharges) but qualitative (temporal patterns of states such as flowing water, stagnant pools or lack of surface water), ii) stream flow records do not inform on the temporal occurrence of stagnant pools, which act as refugees for many species during the cessation of flow, iii) as most of the temporary streams are ungauged, the evaluation of their regime must be determined by using alternative methods such as remote sensing or citizen science, and iv) the biological quality assessment of the ecological status of a temporary stream must be conducted following a sampling schedule adapted to the flow regime and using adequate reference conditions. In order to overcome these challenges using an operational approach, the TREHS freely available software tool has been developed within the EU LIFE TRIVERS project (LIFE13 ENV/ES/000341). This software allows for the input of information coming from flow simulations obtained using any rainfall-runoff model (to set an unimpacted reference stream regime) and compares them with the information obtained from flow gauging records, interviews made to local citizens, instantaneous observations made by

  19. The Temporal Organization Grid: A New Classification System of Temporary Organizations

    Directory of Open Access Journals (Sweden)

    Vallari Chandna

    2017-03-01

    Full Text Available With the increased recognition of the key role played by time in processes and outcomes, there has been a renewed focus on temporary organizations. Temporary organizational forms tend to receive attention due to certain characteristics that are unique to them, as compared to permanent organizations, with regard to issues like trust, communication, organizational structure, innovation and creativity among others. They have also been known to generate significant benefits for the organizations participating in them. But to study them in detail, a comprehensive classification system of temporary organizations is needed, which has so far been missing in the extant literature. This paper sets forth a classification grid for temporary organizations which is its primary purpose and also examines the different strategically important variables that further define the typological framework and that act as determinants of success of these temporary organizations.

  20. Phosphate Barriers for Immobilization of Uranium Plumes

    Burns, Peter C.

    2004-01-01

    Uranium contamination of the subsurface remains a persistent problem plaguing remedial design at sites across the U.S. that were involved with production, handling, storage, milling, and reprocessing of uranium for both civilian and defense related purposes. Remediation efforts to date have relied upon excavation, pump-and-treat, or passive remediation barriers (PRB?s) to remove or attenuate uranium mobility. Documented cases convincingly demonstrate that excavation and pump-and-treat methods are ineffective for a number of highly contaminated sites. There is growing concern that use of conventional PRB?s, such as zero-valent iron, may be a temporary solution to a problem that will persist for thousands of years. Alternatives to the standard treatment methods are therefore warranted. The core objective of our research is to demonstrate that a phosphorus amendment strategy will result in a reduction of dissolved uranium to below the proposed drinking water standard. Our hypothesis is that long-chain sodium polyphosphate compounds forestall precipitation of sparingly soluble uranyl phosphate compounds, which is paramount to preventing fouling of wells at the point of injection

    A special purpose data base for physical security barriers has been developed. In addition to barriers, the entities accommodated by the Barrier Data Base (BDB) include threats and references. A threat is established as a configuration of people and equipment which has been employed to penetrate (or attempt to penetrate) a barrier. References are used to cite publications pertinent to the barriers and threats in the data base. Utilization and maintenance of the Barrier Data Base is achieved with LIST, QUERY, ENTER, DELETE, and CHANGE commands which are used to manipulate the data base entities

  3. Geophysical characterization of subsurface barriers

    International Nuclear Information System (INIS)

    Borns, D.J.

    1995-08-01

    An option for controlling contaminant migration from plumes and buried waste sites is to construct a subsurface barrier of a low-permeability material. The successful application of subsurface barriers requires processes to verify the emplacement and effectiveness of barrier and to monitor the performance of a barrier after emplacement. Non destructive and remote sensing techniques, such as geophysical methods, are possible technologies to address these needs. The changes in mechanical, hydrologic and chemical properties associated with the emplacement of an engineered barrier will affect geophysical properties such a seismic velocity, electrical conductivity, and dielectric constant. Also, the barrier, once emplaced and interacting with the in situ geologic system, may affect the paths along which electrical current flows in the subsurface. These changes in properties and processes facilitate the detection and monitoring of the barrier. The approaches to characterizing and monitoring engineered barriers can be divided between (1) methods that directly image the barrier using the contrasts in physical properties between the barrier and the host soil or rock and (2) methods that reflect flow processes around or through the barrier. For example, seismic methods that delineate the changes in density and stiffness associated with the barrier represents a direct imaging method. Electrical self potential methods and flow probes based on heat flow methods represent techniques that can delineate the flow path or flow processes around and through a barrier

    Two technical bases of the Northern Fleet were created in the Russian northwest in the 1960s at Andreeva in the Kola Bay and Gremikha village on the coast of the Barents Sea. They maintained nuclear submarines, performing receipt and storage of radioactive waste and spent nuclear fuel. No further stored material was received after 1985. These technical bases have since been re-categorised as sites of temporary storage. It is necessary to note that, during the storage of RW and SNF, certain conditions arose which resulted in failure of the storage barrier system, resulting in release of radionuclides. Remediation activities at the site focus on reduction of major risks associated with most hazardous radioactive source terms. In addition, the long term management of the sites includes consideration of how to remediate contaminated areas, not only because they affect continuing work at the site, but also because this work will influence final radiological status of the sites. The optimum approach to remediation will be affected by how quickly radionuclides could move, both during the remediation works and, so far as any residual activity is concerned, after the works are completed. Present investigations reported here are directed to determination of sorption-desorption parameters of radionuclides in the studied areas, which will affect their underground migration, with the purpose of accounting for regional peculiarities in optimization process of the STSs remediation. The work is being carried out by the TSO State Research Centre - Institute of Biophysics, of Russian Federation, with assistance from western experts. The work forms part of a regulatory collaboration programme on-going between the Norwegian Radiation Protection Authority and the Federal Medical-Biological Agency which is designed to support the development of norms and standards to be applied in the remediation of these sites of temporary storage.

    We study autocorrelation functions in symmetric barrier billiards for golden mean trajectories with arbitrary barriers. Renormalization analysis reveals the presence of a chaotic invariant set and thus that, for a typical barrier, there are chaotic correlations. The chaotic renormalization set is the analogue of the so-called orchid that arises in a generalized Harper equation. (paper)

    To describe the role of temporary retrograde ureteral catheterization at the time of fertility-sparing radical vaginal or abdominal trachelectomy in women with early-stage cervical cancer. We analyzed a prospectively maintained database of all patients with cervical cancer who were explored for radical vaginal or abdominal trachelectomy at our institution. Cystourethroscopy and ureteral catheterization were performed prior to the vaginal or abdominal operation in all patients, except two pediatric ones. Temporary bilateral retrograde ureteral catheters were planned for all patients as part of our routine procedure to facilitate identification of the distal ureters. 5Fr whistle-tip or open-ended catheters were used and usually advanced to approximately 20 cm. Catheters were removed at the end of the operation in all cases. All catheters were inserted by a gynecologic oncology fellow or attending. Between 11/01 and 12/05, 40 patients were taken to the operating room for planned fertility-sparing radical vaginal or abdominal trachelectomy. We previously reported on two pediatric patients; they are excluded from this report. The median age for adult patients was 32 years (mean, 31.6; range, 23-40). International Federation of Gynecology and Obstetrics (FIGO) stage included IB1 (26), IA2 (6), and IA1 with lymphovascular invasion (6). Thirty-four patients underwent radical vaginal trachelectomy and four underwent a radical abdominal trachelectomy. Two (5%) of 38 patients required immediate completion radical hysterectomy due to extensive endocervical disease (one in the vaginal group and one in the abdominal group). Bilateral ureteral catheters were inserted successfully in 37 (97%) of 38 patients and facilitated identification of the distal ureter during the dissection. In one case, the right ureteral orifice could not be successfully catheterized, and the case was completed with unilateral catheterization. The estimated time to perform this part of the operation was

  10. Design of engineered sorbent barriers

    International Nuclear Information System (INIS)

    Jones, E.O.; Freeman, H.D.

    1988-08-01

    A sorbent barrier uses sorbent material such as activated carbon or natural zeolites to prevent the migration of radionuclides from a low-level waste site to the aquifer. The sorbent barrier retards the movement of radioactive contaminants, thereby providing time for the radionuclides to decay. Sorbent barriers can be a simple, effective, and inexpensive method for reducing the migration of radionuclides to the environment. Designing a sorbent barrier consists of using soil and sorbent material properties and site conditions as input to a model which will determine the necessary sorbent barrier thickness to meet contaminant limits. The paper will cover the following areas: techniques for measuring sorption properties of barrier materials and underlying soils, use of a radionuclide transport model to determine the required barrier thickness and performance under a variety of site conditions, and cost estimates for applying the barrier. 8 refs., 6 figs., 1 tab

    A sorbent barrier uses sorbent material such as activated carbon or natural zeolites to prevent the migration of radionuclides from a low-level waste site to the aquifer. The sorbent barrier retards the movement of radioactive contaminants, thereby providing time for the radionuclides to decay. Sorbent barriers can be a simple, effective, and inexpensive method for reducing the migration of radionuclides to the environment. Designing a sorbent barrier consists of using soil and sorbent material properties and site conditions as input to a model which will determine the necessary sorbent barrier thickness to meet contaminant limits. The paper covers the following areas: techniques for measuring sorption properties of barrier materials and underlying soils, use of a radionuclide transport model to determine the required barrier thickness and performance under a variety of site conditions, and cost estimates for applying the barrier

    2009-01-01

    Full text: An IAEA-led international team of nuclear reactor safety experts completed a safety review mission on 18 February at the High Flux Reactor (HFR) at Petten, in the Netherlands. The mission was conducted at the request of the Government of the Netherlands to review a set of previous evaluations made by the Dutch regulatory authority regarding the reactor's safety. The IAEA mission made a series of recommendations to enhance the safety of the year-long temporary restart. The recommendations included: - Performance of the monitoring system for leaks should be rigorously checked during the interim year of operation; - Temporary operation of the HFR cannot be extended beyond 1 March 2010; and - In case of any detected leakage from the coolant pipes, the reactor should be shut down immediately and repaired before restarting. The international team was composed of one IAEA staff member and five external experts from Argentina, Canada, France, India and South Africa. The IAEA's main conclusions and recommendations were presented in The Hague to the Ministry of Housing, Spatial Planning and the Environment and several other ministries. The team also provided a summary of its findings to the Netherlands Regulatory Authority. The team's final report will be submitted within two weeks. The HFR at Petten is one of five research reactors in the world that produces radioactive medical isotopes, used an estimated 40 million times annually for cancer treatment and the diagnosis of heart attacks. Prolonged outages at any of these five reactors have a far-reaching impact on medical treatments and diagnoses for patients around the globe. Since August 2008, the HFR reactor has been in shut-down status due to corrosion of pipes in its primary cooling circuit. The Nuclear Research and Consultancy Group (NRG), the operating organization for Petten, proposed a one-year restart of the HFR reactor, which was approved by the Dutch regulatory body. The reactor then resumed operation

    The Hanford Site Protective Barrier Development Program was jointly developed by Pacific Northwest Laboratory (PNL) and Westinghouse Hanford Company (WHC) to design and test an earthen cover system(s) that can be used to inhibit water infiltration; plant, animal, and human intrusion; and wind and water erosion. The joint PNL/WHC program was initiated in FY 1986. To date, research findings support the initial concepts of barrier designs for the Hanford Site. A fine-soil surface is planned to partition surface water into runoff and temporary storage. Transpiration by vegetation that grows in the fine-soil layer will return stored water to the atmosphere as will surface evaporation. A capillary break created by the interface of the fine-soil layer and coarser textured materials below will further limit the downward migration of surface water, making it available over a longer period of time for cycling to the atmosphere. Should water pass the interface, it will drain laterally through a coarse textured sand/gravel layer. Tested barrier designs appear to work adequately to prevent drainage under current and postulated wetter-climate (added precipitation) conditions. Wind and water erosion tasks are developing data to predict the extent of erosion on barrier surfaces. Data collected during the last year confirm the effectiveness of small burrowing animals in removing surface water. Water infiltrating through burrows of larger mammals was subsequently lost by natural processes. Natural analog and climate change studies are under way to provide credibility for modeling the performance of barrier designs over a long period of time and under shifts in climate. 10 refs., 30 figs

    In this paper a realistic selfconsistent calculation of an abrupt metal-semiconductor junction is presented by means of a tight-binding approach. A specific Si-Ag junction has been considered, and the charge neutrality level as well as the barrier height have been determined in good agreement with experiments. For a generaljunction it is shown that the interface properties depend essentially on the characteristics of the first metal layer and its interaction with the semiconductor. (Author) [pt

    We propose a ground-state approach to realizing quantum computers. This scheme is time-independent and inherently defends against decoherence by possessing an energy barrier to excitation. We prove that our time-independent qubits can perform the same algorithms as their time-dependent counterparts. Advantages and disadvantages of the time-independent approach are described. A model involving quantum dots is provided for illustration

    1997-01-01

    Engineered barriers, both vertical and horizontal, have been used to isolate hazardous wastes from contact, precipitation, surface water and groundwater. The primary objective of this study was to determine the performance of subsurface barriers installed throughout the U.S. over the past 20 years to contain hazardous wastes. Evaluation of Resource Conservation and Recovery Act (RCRA) Subtitle C or equivalent caps was a secondary objective. A nationwide search was launched to select hazardous waste sites at which vertical barrier walls and/or caps had been used as the containment method. None of the sites selected had an engineered floor. From an initial list of 130 sites, 34 sites were selected on the basis of availability of monitoring data for detailed analysis of actual field performance. This paper will briefly discuss preliminary findings regarding the design, construction quality assurance/construction quality control (CQA/CQC), and monitoring at the 34 sites. In addition, the short-term performance of these sites (less than 5 years) is presented since very little long-term performance data was available

    A double Schottky barrier is often formed at the grain boundary in polycrystalline semiconductors. The barrier height is shown to fluctuate in value due to the random nature of the impurity positions. The magnitude of the fluctuations is 0.1 eV, and the fluctuations cause the barrier height measured by capacitance to differ from the one measured by electrical conductivity

    We present a case of a patient with pacemaker dependence secondary to complete heart block who developed loss of capture of her temporary pacemaker. Patient developed torsades de pointes then ventricular fibrillation, requiring CPR and external cardioversion. After patient was stabilized, it was noticed that loss of capture of pacemaker corresponded with nursing care, when the pulse generator was lifted off patient׳s chest wall, and that patient׳s temporary pacing system had been programmed to unipolar mode without knowledge of attending cardiologist. This case highlights the importance of communication ensuring all caregivers are aware of mode of the temporary pacing system.

    A reach at the estuary of Krathis River in Greece was used to assess how in-stream processes alter its hydrologic and biogeochemical regime. Krathis River exhibited high annual flow variability and its transmission losses become significant, especially during the dry months. These transmission losses are enhanced in chemistry due to release of nutrients from river sediments. These fluxes are significant because they correspond to 11% of the dissolved inorganic nitrogen flux of the river. Release of nitrogen species was influenced by temperature, while release of phosphate was not because phosphate levels were below the equilibrium concentration. There is a significant amount of sediments with fine composition that create "hot spot" areas in the river reach. These sediments are mobilized during the first flush events in the fall carrying with them a significant load of nutrient and suspended matter to the coastal zone. The nutrient organic content of sediments was also significant and it was studied in terms of its mineralization capacity. The capacity for mineralization was influenced by soil moisture, exhibiting significant capacity even at moisture levels of 40%. Temporary rivers are sensitive ecosystems, vulnerable to climate changes. In-stream processes play a significant role in altering the hydrology and biogeochemistry of the water and its impacts to the coastal zone.

    The aim of this project is to develop an image guided protocol for placement of a temporary anchorage device without surgically reflecting a mucoperiosteal flap. Eighteen orthodontic cases were selected for skeletal anchorage from the department of orthodontics at Case University. CBCT images of the subjects were taken using the Hitachi CB MercuRay system set at 15 mA, 120 kVp. CBCT images evaluated the ideal location for TAD placement in three dimensions. Horizontal and vertical linear measurements were taken from fixed dental landmarks to clearly define the location for placement. Transverse slices were used to evaluate the thickness of the buccal plate. Using the transverse view, the angle of insertion was determined such that the maximum buccal plate surface area would contact the screw. TADs were placed in the optimum location, with the most appropriate angle of insertion using a closed approach and with minimal local anesthesia and without flap elevation. Results: All TADs were placed without anatomic encroachment and enabled fixed orthodontic anchorage. (orig.)

    Although electroconvulsive therapy (ECT) is generally considered effective against depression, it remains controversial because of its association with retrograde memory loss. Here, we assessed memory after ECT in circumstances most likely to yield strong retrograde amnesia. A cohort of patients undergoing ECT for major depression was tested before and after ECT, and again at 3-months follow-up. Included were 21 patients scheduled to undergo bilateral ECT for severe major depression and 135 controls matched for gender, age, education, and media consumption. Two memory tests were used: a verbal learning test to assess anterograde memory function, and a remote memory test that assessed memory for news during the course of one year. Before ECT the patients' scores were lower than those of controls. They were lower again after treatment, suggesting retrograde amnesia. At follow-up, however, memory for events before treatment had returned to the pre-ECT level. Memory for events in the months after treatment was as good as that of controls. The sample size in this study was not large. Moreover, memory impairment did not correlate with level of depression, which may be due to restriction of range. Our results are consistent with the possibility that ECT as currently practiced does not cause significant lasting retrograde amnesia, but that amnesia is mostly temporary and related to the period of impairment immediately following ECT.

    1998-12-01

    The Mobile Integrated Temporary Utility System (MITUS) integrates portable electrical power along with communications and emergency alarm and lighting capabilities to provide safe, centralized power to work areas that need to be de-energized for decommissioning work. MITUS consists of a portable unit substation; up to twenty portable kiosks that house the power receptacles, communications, and emergency alarm and lighting systems; and a central communications unit. This system makes sequential decommissioning efforts efficient and cost-effective by allowing the integrated system to remain intact while being moved to subsequent work sites. Use of the MITUS also eliminates the need to conduct zero-energy tests and implement associated lock-out/tag-out procedures at partially de-energized facilities. Since the MITUS is a designed system, it can be customized to accommodate unique facility conditions simply by varying kiosks and transformer configurations. The MITUS is an attractive alternate to the use of portable generators with stand-alone communications and emergency system. It is more cost-effective than upgrading or reconfiguring existing power distribution systems

    Radiation therapy can cause corneal and conjuctival abnormalities that sometimes require surgical treatment. Corneal stem cell dysfunction is described, which recovered after the cessation of radiation. Methods - A 44-year-old man developed a corneal epithelial abnormality associated with conjuctival and corneal inflammation following radiation therapy for maxillary cancer. Examination of brush cytology samples showed goblet cells in the upper and lower parts of the cornea, which showed increased fluorescein permeability, and intraepithelial lymphocytes. Impression cytology showed goblet cells in the same part of the cornea. Specular microscopy revealed spindle type epithelial cells. Patient follow up included artificial tears and an antibiotic ophthalmic ointment. The corneal abnormalities resolved after 4 months with improved visual acuity without any surgical intervention, but the disappearance of the palisades of Vogt did not recover at 1 year after radiation. Radiation therapy in this patient caused temporary stem cell dysfunction which resulted in conjunctivalisation in a part of the cornea. Although limbal stem cell function did not fully recover, this rare case suggested that medical options should be considered before surgery. (Author)

    2000-01-01

    The aim of this report is to present an analysis of the geological settings along Kozloduy NPP area from the viewpoint of a natural, protective barrier against unacceptable radionuclides migration in the environment. Possible sources of such migration could be an eventual accident in an active nuclear plant; radioactive releases from decommissioned Power Units or from temporary or permanent radioactive waste repositories. The report is directed mainly to the last case, and especially to the site selection for near surface short lived low and intermediate level (LILW) radioactive repository. The main conclusion of the geological settings assessment and of the many years monitoring is that the Kozloduy NPP area offers good possibilities for site selection of LILW repository. (author)

  14. Barrier mechanisms in the Drosophila blood-brain barrier

    Directory of Open Access Journals (Sweden)

    Samantha Jane Hindle

    2014-12-01

    Full Text Available The invertebrate blood-brain barrier field is growing at a rapid pace and, in recent years, studies have shown a physiologic and molecular complexity that has begun to rival its vertebrate counterpart. Novel mechanisms of paracellular barrier maintenance through GPCR signaling were the first demonstrations of the complex adaptive mechanisms of barrier physiology. Building upon this work, the integrity of the invertebrate blood-brain barrier has recently been shown to require coordinated function of all layers of the compound barrier structure, analogous to signaling between the layers of the vertebrate neurovascular unit. These findings strengthen the notion that many blood-brain barrier mechanisms are conserved between vertebrates and invertebrates, and suggest that novel findings in invertebrate model organisms will have a significant impact on the understanding of vertebrate BBB functions. In this vein, important roles in coordinating localized and systemic signaling to dictate organism development and growth are beginning to show how the blood-brain barrier can govern whole animal physiologies. This includes novel functions of blood-brain barrier gap junctions in orchestrating synchronized neuroblast proliferation, and of blood-brain barrier secreted antagonists of insulin receptor signaling. These advancements and others are pushing the field forward in exciting new directions. In this review, we provide a synopsis of invertebrate blood-brain barrier anatomy and physiology, with a focus on insights from the past 5 years, and highlight important areas for future study.

    We characterize and compare the self-reported physical exposures, work tasks, and OSHA-10 training in a non-probabilistic sample of temporary and payroll construction workers. In June 2016, a total of 250 payroll and temporary general laborers employed at Florida construction sites completed a survey at the job site as part of the falls reported among minority employees (FRAME) study. Workers employed through temp agencies (57.1%) were significantly more likely to report moving or lifting materials more than 100 pounds than payroll workers (38.5%; P < 0.01). Temporary construction workers with 10-hour OSHA training (22.2%) spent significantly less time with intense hand use/awkward hand posture than temporary workers without 10-hour OSHA training (46.9%; P = 0.048). Temp construction workers with OSHA 10-hour training reported less hazardous physical postures than workers without the same training.

    Full Text Available This paper evaluates the size and duration of temporary and permanent stock price innovations on Croatian capital market in the structural VAR (vector autoregression framework with Blanchard and Quah (1989 decomposition. The purpose is to identify the effects of temporary price innovations in order to determine to which extent future stock prices can be predicted. Temporary components present in stock prices are explained throughout the mean-reversion hypothesis. This means that stock prices deviate from the fundamental values, but they will revert to their mean. In that way, to some extent, it is possible to predict future price movements. The results show that for the observed period from January 2000 to September 2013, temporary innovations account for only 2.62% of price variability over a two-year horizon. This means that forecasting the future movements of stock prices on Zagreb Stock Exchange is a difficult task.

  20. Temporary workers in the nuclear power industry: implications for the waste management program

    International Nuclear Information System (INIS)

    Melville, M.H.

    1984-01-01

    The employment of large number of temporary workers has become a growing and permanent characteristic of the nuclear power industry. In order to stay within the limits governing individual exposure to radiation in the workplace, the occupational risk has been spread among a larger segment of the population. Temporary workers, who make up one-third of the industry's work force, bear a disproportionate share of half the total annual occupational radiation dose. At issue is whether temporary workers should be grouped with the public at large or with the nuclear industry's work force, whose maximum limits are at least 10 times higher. This issue is relevant at a time when the search for a way to manage the mounting radioactive wastes will increase both the permanent and temporary work force. 44 references, 4 figures, 4 tables

    The aim of this study is to describe critical care nurses (CCN's) experiences of working with or as temporary agency staff. This explorative qualitative study is based on interviews with five agency CCNs and five regular CCNs, a total of ten interviews, focusing on the interviewees' experiences of daily work and temporary agency staffing. The interviews were analysed manually and thematically following an inductive approach. Four themes that illustrate both similarities and differences between regular and temporary agency CCNs emerged: "working close to patients versus being responsible for everything", "teamwork versus independence", "both groups needed" and "opportunities and challenges". The study findings illustrate the complexity of the working situation for agency and regular staff in terms of the organisation and management of the temporary agency nurses and the opportunities and challenges faced by both groups.

    Urethroplasty is an effective treatment for men with anterior urethral strictures, but is utilized less frequently than ineffective treatments such as internal urethrotomy. We sought to identify provider-level barriers to urethroplasty. An anonymous online survey was emailed to all Mid-Atlantic American Urological Association members. Six scenarios in which urethroplasty was the most appropriate treatment were presented. Primary outcome was recommendation for urethroplasty in ≥ three clinical scenarios. Other factors measured include practice zip code, urethroplasty training, and proximity to a urethroplasty surgeon. Multivariate logistic regression identified factors associated with increased likelihood of urethroplasty recommendation. Of 670 members emailed, 109 (16%) completed the survey. Final analysis included 88 respondents. Mean years in practice was 17.2. Most respondents received formal training in urethroplasty: 43 (49%) in residency, 5 (6%) in fellowship, and 10 (11%) in both; 48 respondents (55%) had a urethroplasty surgeon in their practice, whereas 18 (20%) had a urethroplasty surgeon within 45 minutes of his or her primary practice location. The only covariate that was associated with an increased likelihood of recommending urethroplasty in ≥ three scenarios was formal urethroplasty training. Most members (68%) reported no barriers to referring patients for urethroplasty; the most common barriers cited were long distance to urethroplasty surgeon (n 5 13, 15%) and concern about complications (n 5 8, 9%). Urethroplasty continues to be underutilized in men with anterior urethral strictures, potentially due to lack of knowledge dissemination and access to a urethroplasty surgeon. Appropriate urethroplasty utilization may increase with greater exposure to urethroplasty in training.

  4. Exact Sight Distance Determination on Compound Vertical and Horizontal Curves in the Presence of Road Barriers

    Directory of Open Access Journals (Sweden)

    Chiu Liu, PhD, PE, PTOE

    2013-06-01

    Full Text Available The sight distance (SD on a three-dimensional (3-d compound curve has been studied recently in the absence of obstacles at road sides. Often, physical barriers are installed at road sides or in a roadway median for reducing potential collision severities; these rigid, semi-rigid, or even temporary cushion-type barriers can limit or reduce the driver's sight distance, depending on their horizontal offset distances away from the nearest edge of traveled way (ETW. The closer a barrier to the ETW is, the shorter the driver's sight distance would be. Since most barriers are constructed to prevent running-off road or crossing-median collisions, it is crucial to check whether the installation would reduce the driver's sight distance and potentially cause other traffic collisions such as rear-end or side swipe collisions. In this paper, an exact analytic framework is formulated with derived equations the first time to calculate the sight distance on a 3-d compound curve in the presence of a median barrier, a roadside barrier, or a temporary cushion or barrier used for construction or other maintenance purposes. This framework provides an engineer a handy tool to examine the possible change of SD in the presence of a barrier and choose the required horizontal offset/clearance of a barrier from the nearest traveled way edge to meet certain design criteria or standards. This critical offset distance determined using this framework not only reinforces the importance of having roadside clearance recovery zones on highways but also provides a method to determine its horizontal clearance from a different standpoint. This analytic framework can easily be programmed into an Excel spreadsheet to evaluate the design of a physical barrier and its potential influence on sight distance along a 3-d compound horizontal and vertical curve. Transportation engineers or practitioners may find this design tool handy and useful once the programmed spreadsheet is saved in a

    This study offers a critical look at how corporate-level language management influences front-line language practices among employees in three multinational corporations (MNCs) headquartered in Scandinavia. Based on interview and document data, we examine, firstly, what front-line practices...... employees use to cross language boundaries in their everyday work, and, secondly, how these practices relate to top-down language management in the case companies. Our findings show that employees are often dependent on ad hoc and informal solutions in cross- language situations, which leads us...... to a discussion of how a company’s language policy may be seen as both support and a barrier....

    The Defense Waste Processing Facility is being constructed at The Savannah River Plant for the containerization of high-level nuclear waste in a wasteform for eventual permanent disposal. The waste will be incorporated in molten glass and solidified in type 304L stainless steel canisters, 2-feet in diameter x 9-feet 10-inches long, containing a flanged 6-in.-diam pipe fill-nozzle. The canisters have a minimum wall thickness of 3/8 in. Utilizing the heat from the glass filling operation, a shrink-fit seal for a plug in the end of the canister fill nozzle was developed that: will withstand the radioactive environment; will prevent the spread of contamination, and will keep moisture and water from entering the canister during storage and decontamination of the canister by wet-frit blasting to remove smearable and oxide-film fixed radioactive nuclides; is removable and can be replaced by a new oversize plug in the event the seal fails the pressure decay leakage test ( -4 atm cc/sec helium); will keep the final weld closure clean and free of nuclear contamination; will withstand being pressed into the nozzle without exposing external contamination or completely breaking the seal; is reliable; and is easily installed. The seal consists of: a removable sleeve (with a tapered bore) which is shrink-fitted into the nozzle bore during canister fabrication; and a tapered plug which is placed into the sleeved nozzle after the canister is filled with radioactive molten glass. A leak-tight shrink-fit seal is formed between the nozzle, sleeve, and plug upon temperature equilibrium. The temporarily sealed canister is transferred from the Melt cell to the Decon cell, and the surface is decontaminated. Next it is transferred to the Weld/Test cell where the temporary seal is pressed down into the nozzle, revealing a clean cavity where the canister final closure weld is made

    Open globe injuries are full-thickness injuries sustained to the eye wall (cornea or sclera), which cause immediate drops in intraocular pressure that may lead to retinal detachment and permanent vision loss if not treated rapidly after injury. The current standard of care for open globe injuries consists of suturing the margins closed, but the technique can be time-consuming, requires specialized training and equipment, and can lead to patient discomfort, abrasion, and infection from eye rubbing. We engineered an injectable, thermoresponsive sealant (TRS) and a custom tool to occlude open globe injuries. The smart hydrogel sealant consists of physically cross-linked N -isopropylacrylamide copolymerized with butylacrylate. At low temperatures, it can be injected as a liquid, and when raised to body temperature, a heat-induced gelation converts the hydrogel into a solidified occlusion. The sealant can be repositioned or removed without causing additional trauma via exposure to cold water. In vitro and ex vivo assessments of mechanical adhesion to eye tissue revealed maintenance of intraocular pressure that is five times greater than the physiological range with reversible seal strength comparable to cyanoacrylate (super glue). In vivo assessment in a rabbit model of ocular trauma demonstrated ease of use for TRS deployment, statistically significant improvement in wound sealing, and no evidence of neurotoxicity, retinal tissue degradation, or significant chronic inflammatory response after 30 days of exposure. Given the advantages of body heat-induced gelation, rapid reversible occlusion, and in vivo safety and efficacy, shape-adaptable TRSs have translational potential as smart wound sealants for temporary occlusion of surgical incisions or traumatic injuries.

  13. Atlantic leatherback migratory paths and temporary residence areas.

    Directory of Open Access Journals (Sweden)

    Sabrina Fossette

    Full Text Available BACKGROUND: Sea turtles are long-distance migrants with considerable behavioural plasticity in terms of migratory patterns, habitat use and foraging sites within and among populations. However, for the most widely migrating turtle, the leatherback turtle Dermochelys coriacea, studies combining data from individuals of different populations are uncommon. Such studies are however critical to better understand intra- and inter-population variability and take it into account in the implementation of conservation strategies of this critically endangered species. Here, we investigated the movements and diving behaviour of 16 Atlantic leatherback turtles from three different nesting sites and one foraging site during their post-breeding migration to assess the potential determinants of intra- and inter-population variability in migratory patterns. METHODOLOGY/PRINCIPAL FINDINGS: Using satellite-derived behavioural and oceanographic data, we show that turtles used Temporary Residence Areas (TRAs distributed all around the Atlantic Ocean: 9 in the neritic domain and 13 in the oceanic domain. These TRAs did not share a common oceanographic determinant but on the contrary were associated with mesoscale surface oceanographic features of different types (i.e., altimetric features and/or surface chlorophyll a concentration. Conversely, turtles exhibited relatively similar horizontal and vertical behaviours when in TRAs (i.e., slow swimming velocity/sinuous path/shallow dives suggesting foraging activity in these productive regions. Migratory paths and TRAs distribution showed interesting similarities with the trajectories of passive satellite-tracked drifters, suggesting that the general dispersion pattern of adults from the nesting sites may reflect the extent of passive dispersion initially experienced by hatchlings. CONCLUSIONS/SIGNIFICANCE: Intra- and inter-population behavioural variability may therefore be linked with initial hatchling drift scenarios

    Purpose. To determine the efficacy of celiac plexus block during thermoablation of liver metastases. Methods. Fifty-five consecutive patients underwent thermoablation therapy of liver tumors by laser-induced thermotherapy. Twenty-nine patients received a temporary celiac plexus block, 26 patients acted as control group. In both groups fentanyl and midazolam were administered intravenously upon request of the patient. The duration of the intervention, consumption of opiates, and individual pain sensations were documented. Results. No complications resulting from the celiac plexus block were recorded. Celiac plexus block significantly reduced the amount of pain medication used during thermoablation therapy of liver tumors (with block, 2.45 μg fentanyl per kg body weight; without block, 3.58 μg fentanyl per kg body weight, p < 0.05; midazolam consumption was not reduced) in patients with metastases ≤5 mm from the liver capsule. For metastases farther away from the capsule no significant differences in opiate consumption were seen. Celiac plexus block reduced the time for thermoablation significantly (178 min versus 147 min, p < 0.05) no matter how far the metastases were from the liver capsule. Average time needed to set the block was 12 min (range 9-15 min); additional costs for the block were marginal. As expected (as pain medications were given according to individual patients' needs) pain indices did not differ significantly between the two groups. Conclusion. In patients with liver metastases ≤5 mm from the liver capsule, celiac plexus block reduces the amount of opiates necessary, simplifying patient monitoring. In addition celiac plexus block reduces intervention time, with positive effects on overall workflow for all patients

  15. A comparison of groundwater investigation using temporary points versus permanent monitoring wells

    Groundwater investigation within the environmental industry is most often conducted using permanent monitoring wells. A monitoring well, as the term suggests, is permanent to the extent that it is fixed in place to monitor groundwater quality in its immediate vicinity at any given time over the course of an environmental project. Because monitoring wells are relatively time consuming and expensive to construct, a minimum number of wells is normally installed as part of a single investigation event. The initial information obtained from monitoring wells could also be obtained from temporary groundwater sampling points. Temporary points generally are smaller in diameter than monitoring wells, are installed to provide a one time snap shot of the subsurface, and are removed at the completion of the investigation. Since temporary points are usually easier to install and less expensive than monitoring wells, more temporary points can be installed over a single investigation event and can often reduce or eliminate subsequent assessment(s). A brief discussion of temporary point installation and sampling is offered before considering two case studies within the context of the above advantages to temporary point installation. One case study focuses on vertical delineation of dissolved petroleum hydrocarbons, while the second case study discusses lateral delineation of light nonaqueous phase liquid (LNAPL)

  16. Temporary Workforce Planning with Firm Contracts: A Model and a Simulated Annealing Heuristic

    Directory of Open Access Journals (Sweden)

    Muhammad Al-Salamah

    2011-01-01

    Full Text Available The aim of this paper is to introduce a model for temporary staffing when temporary employment is managed by firm contracts and to propose a simulated annealing-based method to solve the model. Temporary employment is a policy frequently used to adjust the working hour capacity to fluctuating demand. Temporary workforce planning models have been unnecessarily simplified to account for only periodic hiring and laying off; a company can review its workforce requirement every period and make hire-fire decisions accordingly, usually with a layoff cost. We present a more realistic temporary workforce planning model that assumes a firm contract between the worker and the company, which can extend to several periods. The model assumes the traditional constraints, such as inventory balance constraints, worker availability, and labor hour mix. The costs are the inventory holding cost, training cost of the temporary workers, and the backorder cost. The mixed integer model developed for this case has been found to be difficult to solve even for small problem sizes; therefore, a simulated annealing algorithm is proposed to solve the mixed integer model. The performance of the SA algorithm is compared with the CPLEX solution.

  17. Stability of barrier buckets with zero RF-barrier separations

    2005-03-01

    A barrier bucket with very small separation between the rf barriers (relative to the barrier widths) or even zero separation has its synchrotron tune decreasing rather slowly from a large value towards the boundary of the bucket. As a result, large area at the bucket edges can become unstable under the modulation of rf voltage and/or rf phase. In addition, chaotic regions may form near the bucket center and extend outward under increasing modulation. Application is made to those barrier buckets used in the process of momentum mining at the Fermilab Recycler Ring.

  18. Phosphate Barriers for Immobilization of Uranium Plumes

    2005-01-01

    Uranium contamination of the subsurface has remained a persistent problem plaguing remedial design at sites across the U.S. that were involved with production, handling, storage, milling, and reprocessing of fissile uranium for both civilian and defense related purposes. Remediation efforts to date have relied upon excavation, pump-and-treat, or passive remediation barriers (PRB's) to remove or attenuate uranium mobility. Documented cases convincingly demonstrate that excavation and pump-and-treat methods are ineffective for a number of highly contaminated sites. There is growing concern that use of conventional PRB?s, such as zero-valent iron, are a temporary solution to a problem that will persist for thousands of years. Alternatives to the standard treatment methods are therefore warranted. The core objective of our research is to demonstrate that a phosphorus amendment strategy will result in a reduction of dissolved uranium to below the proposed drinking water standard. Our hypothesis is that long-chain polyphosphate compounds forestall precipitation of sparingly soluble uranyl phosphate compounds, which is key to preventing fouling of wells at the point of injection. Our other fundamental objective is to synthesize and correctly characterize the uranyl phosphate phases that form in the geochemical conditions under consideration. This report summarizes work conducted at the University of Notre Dame through November of 2003 under DOE grant DE-FG07-02ER63489, which has been funded since September, 2002. The objectives at Notre Dame are development of synthesis techniques for uranyl phosphate phases, together with detailed structural and chemical characterization of the myriad of uranyl phosphate phases that may form under geochemical conditions under consideration

    Recently, many interesting applications of the barrier RF system in hadron synchrotrons have been realized. A remarkable example of this is the development of longitudinal momentum mining and implementation at the Fermilab Recycler for extraction of low emittance pbars for the Tevatron shots. At Fermilab, we have barrier RF systems in four different rings. In the case of Recycler Ring, all of the rf manipulations are carried out using a barrier RF system. Here, the author reviews various uses of barrier rf systems in particle accelerators including some new schemes for producing intense proton beam and possible new applications

    The transmission of two particles through the same barrier is considered. The limiting cases are compared when the particles are joined together in a single particle with double mass-energy and potential and when they pass the barrier independently. As an intermediate case a pair of particles bound in a quasideuteron of a finite size is considered. It is shown that long-range collective correlations of particles (of the superfluidity type and others) simplify very much for them passing through high potential barriers. This happens due to the transfer of the additional energy from the particles outside the barriers to those inside it

    1998-03-01

    The Homogeneous Reactor Experiment (HRE) Pond is the site of a former impoundment for radioactive wastes that has since been drained, filled with soil, and covered with an asphalt cap. The site is bordered to the east and south by a tributary that empties into Melton Branch Creek and that contains significant concentrations of radioactive contaminants, primarily 90 Sr. Because of the proximity of the tributary to the HRE disposal site and the probable flow of groundwater from the site to the tributary, it is hypothesized that the HRE Pond is a source of contamination to he creek. As a means for temporary containment of contaminants within the impoundment, a cryogenic barrier technology demonstration was initiated in FY96 with a background hydrologic investigation that continued through FY97. Cryogenic equipment installation was completed in FY97, and freezing was initiated in September of 1997. This report documents the results of a hydrologic and geologic investigation of the HRE Pond/cryogenic barrier site. The purpose of this investigation is to evaluate the hydrologic conditions within and around the impoundment in order to meet the following objectives: (1) to provide a pre-barrier subsurface hydrologic baseline for post-barrier performance assessment; (2) to confirm that the impoundment is hydraulically connected to the surrounding sediments; and (3) to determine the likely contaminant exit pathways from the impoundment. The methods of investigation included water level and temperature monitoring in a network of wells and standpipes in and surrounding the impoundment, a helium tracer test conducted under ambient flow conditions, and geologic logging during the drilling of boreholes for installation of cryogenic probes and temperature monitoring wells

    Full Text Available The articles in this collection share a concern for place, space and bodies as frameworks for thinking about and conducting educational research. The authors range in experience from senior academics, independent educators, beginning and emerging new researchers spanning a range of educational sectors. The articles originate from connections forged within and between Australia and northern countries with visits back and forth between 2004 and 2010. Some of the writers have met each other in these travels and others have not. All have encountered and participated in some way in the work of the space place and body research group, which originated in 2007 as a named research ‘node’ at Monash University.   The space place and body group formed as a result of a process designed to re-imagine research in the Faculty of Education at Monash University in order to address ‘the big questions of our time’. As a leading global university with campuses in Asia and Europe as well as several in Australia, the Dean of the Faculty cited recent evidence that the field of educational research had become too narrowly focused and that new approaches were needed to enliven the field and move it forward. Individualistic research was no longer supported and groups were formed organically around coalitions of interest. The purpose of the space place and body group was to come together to generate new conceptual, theoretical and methodological resources within the core concepts of space, place and body by collaborating across our differences. In the early phase of our development we focused on linked identity (ontological and knowledge (epistemological work, at the intersection of postcolonial and poststructural approaches to place in educational research. A specific interest in alternative and creative methodologies emerged from these onto-epistemological activities.   As part of our process we initiated temporary definitions of space, place and body, to

    The river Ehen, NW England, has been designated as a Special Area of Conservation (SAC) as it hosts England's largest population of freshwater pearl mussels (M. margaritifera). One of the Ehen's main headwater tributary, Ben Gill, was diverted to Ennerdale Lake in the 1970s to help increase the volume of water available for abstraction. Concerns over this diversion on the hydrology and sediment dynamics of the Ehen has led to the reconnection of this temporary stream as part of a project designed to improve habitat conditions for mussels in the Ehen. The reconnection has involved the construction of a new section of channel, following the natural (pre-diversion) course of Ben Gill. This paper presents findings of research designed to track the morphological evolution of the newly created Ben Gill channel. The work follows a previous research in which fluvial dynamics in the Ehen were studied before the reconnection of Ben Gill. Morpho-sedimentary dynamics are analysed at multiple scales: from the movement of individual particles, to changes on channel morphology following competent flow events. Changes in the channel's grain size distributions have been investigated in different sections, while bed mobility has been assessed using a combination of radio frequency identification (RFID) tags inserted into representative particles and painted bed patches. Additionally, digital elevation models (DEMs) of the entire new channel have been constructed by means of automatic digital photogrammetry using high resolution aerial photography taken by an unmanned aerial vehicle (UAV). DEMs of difference (DoD) between major flow events have been used to track lateral and longitudinal changes in the channel at a spatial resolution of less than 5cm. Finally, in order to link sedimentological changes in the new channel to its impact on the main stem Ehen, morpho-sedimentary changes of a gravel bar at the confluence have been monitored combining tracers (i.e. RFID) and repeated

    Hairdressers are occupationally and personally exposed to hair dye substances and adverse reactions from the skin are well known. Currently, little is known about personal exposure to hair dye ingredients and temporary black tattoos. To investigate hairdressers' professional and personal risk exposures and to compare the frequency of temporary tattoos among hairdressers and subjects from the general population. A questionnaire was sent to 1679 Copenhagen hairdressers and 1063 (63.3%) responded; 3471 subjects from the general population in Copenhagen were asked about temporary black tattoos. Of the female hairdressers, 38.3% had coloured hair within the previous week. Adverse skin reactions to own hair dye were reported in 29.5%. In the hairdresser population, no significant association was observed between self-reported adverse skin reactions to hair dye and having had a temporary black tattoo when adjusted for sex, age, and atopy. A total of 19.0% of hairdressers (43.5% of apprentices) and 6.3% of participants from the general population had ever had a temporary black tattoo performed at one point. There were no differences in frequency of eczema after temporary tattooing between hairdressers and subjects in the general population. Almost all hairdressers (99.2%) used gloves for hair colouring, 51% for high/low lighting, 39.6% for perming and 21.1% used gloves for shampooing. In conclusion, skin reactions to hair colour are frequent among Copenhagen hairdressers. Temporary black tattoos were more frequent among hairdressers than in a sample of the general population and increased with decreasing age.

    Producing wells are generally not exploited to their full capacity; however, they may be restimulated. In cases where restimulation is viable, applying the process to an old well is more cost effective than exploiting a new well. Fracturing stimulation (refrac) is a challenging process that may be achieved by isolating portions of the reservoir in order to focus refrac treatment energy. Isolation is traditionally accomplished via the use of a physical barrier within the reservoir or by introducing diverting agents into the flow stream to divert the treatment. The current study developed a new technology of diverters for the restimulation of reservoirs. The new technology consists of a self-assembled polymer that is robust, biodegradable and cost-effective. Results show that the new organic diverters temporarily isolated perforation in the near-wellbore region, allowing to significantly increase the oil production and the recovered original oil in place (OOIP) from the reservoir.

    Full Text Available During embryonic development and adult life, brain cavities and ventricles are filled with cerebrospinal fluid (CSF. CSF has attracted interest as an active signaling medium that regulates brain development, homeostasis and disease. CSF is a complex protein-rich fluid containing growth factors and signaling molecules that regulate multiple cell functions in the central nervous system (CNS. The composition and substance concentrations of CSF are tightly controlled. In recent years, it has been demonstrated that embryonic CSF (eCSF has a key function as a fluid pathway for delivering diffusible signals to the developing brain, thus contributing to the proliferation, differentiation and survival of neural progenitor cells, and to the expansion and patterning of the brain. From fetal stages through to adult life, CSF is primarily produced by the choroid plexus. The development and functional activities of the choroid plexus and other blood–brain barrier (BBB systems in adults and fetuses have been extensively analyzed. However, eCSF production and control of its homeostasis in embryos, from the closure of the anterior neuropore when the brain cavities become physiologically sealed, to the formation of the functional fetal choroid plexus, has not been studied in as much depth and remains open to debate. This review brings together the existing literature, some of which is based on experiments conducted by our research group, concerning the formation and function of a temporary embryonic blood–CSF barrier in the context of the crucial roles played by the molecules in eCSF.

    The surface free energy and dentine bond strength of self-adhesive cements were examined after the removal of temporary cements. The labial dentine surfaces of bovine mandibular incisors were wet ground with #600-grit SiC paper. Acrylic resin blocks were luted to the prepared dentine surfaces using HY Bond Temporary Cement Hard (HY), IP Temp Cement (IP), Fuji TEMP (FT) or Freegenol Temporary Cement (TC), and stored for 1 week. After removal of the temporary cements with an ultrasonic tip, the contact angle values of five specimens per test group were determined for the three test liquids, and the surface-energy parameters of the dentine surfaces were calculated. The dentine bond strengths of the self-adhesive cements were measured after removal of the temporary cements in a shear mode at a crosshead speed of 1.0mm/min. The data were subjected to one-way analysis of variance (ANOVA) followed by Tukey's HSD test. For all surfaces, the value of the estimated surface tension component γ(S)(d) (dispersion) was relatively constant at 41.7-43.3 mJm(-2). After removal of the temporary cements, the value of the γ(S)(h) (hydrogen-bonding) component decreased, particularly with FT and TC. The dentine bond strength of the self-adhesive cements was significantly higher for those without temporary cement contamination (8.2-10.6 MPa) than for those with temporary cement contamination (4.3-7.1 MPa). The γ(S) values decreased due to the decrease of γ(S)(h) values for the temporary cement-contaminated dentine. Contamination with temporary cements led to lower dentine bond strength. The presence of temporary cement interferes with the bonding performance of self-adhesive cements to dentine. Care should be taken in the methods of removal of temporary cement when using self-adhesive cements. Copyright © 2011 Elsevier Ltd. All rights reserved.

    Frequent drying of ponded water, and support of unique, highly specialized assemblages of often rare species, characterize temporary wetlands, such as vernal pools, gilgais, and prairie potholes. As small aquatic features embedded in a terrestrial landscape, temporary wetlands enhance biodiversity and provide aesthetic, biogeochemical, and hydrologic functions. Challenges to conserving temporary wetlands include the need to: (1) integrate freshwater and terrestrial biodiversity priorities; (2) conserve entire ‘pondscapes’ defined by connections to other aquatic and terrestrial systems; (3) maintain natural heterogeneity in environmental gradients across and within wetlands, especially gradients in hydroperiod; (4) address economic impact on landowners and developers; (5) act without complete inventories of these wetlands; and (6) work within limited or non-existent regulatory protections. Because temporary wetlands function as integral landscape components, not singly as isolated entities, their cumulative loss is ecologically detrimental yet not currently part of the conservation calculus. We highlight approaches that use strategies for conserving temporary wetlands in increasingly human-dominated landscapes that integrate top-down management and bottom-up collaborative approaches. Diverse conservation activities (including education, inventory, protection, sustainable management, and restoration) that reduce landowner and manager costs while achieving desired ecological objectives will have the greatest probability of success in meeting conservation goals.

  18. Considerations on National and Union Regulations of Work through a Temporary Employment Agent

    Full Text Available The necessity to adapt the organizational structure of economic operators to the competitive European market requirements has imposed measures that have also influenced labor relations. The permanent and full-time employment relationship has been largely replaced by other types of more flexible labor relationships: temporary employment, part-time work. working from home and temporary assignment through an employment agency. All these types of work relationships are characterized by a decrease of guarantees for the employee and by a reduction of trade union power. Thus, they are considered atypical work relationships. The need to make the flexibility of labor relationships compatible with the protection of employees” rights has been a challenge that must be faced by social policies and also by labor law. In this context, the use of a temporary employment agent has been a tool for flexible working relationships both with the economic operators and within the labor market as a whole. The importane and role of this type of working relationship has, therefore, acquired significant legal, economic and social dimensions, which this study intends to analyze. In a European economy hit by the jobs crisis, reliance on work through a temporary employment agent can be a way to reduce unemployment. This happens only if the temporary workers benefit from legal protection and equal treatment as permanent employees.

    Full Text Available Aim. To evaluate the results of temporary fecal diversion in colorectal and perianal Crohn’s disease. Method. We retrospectively identified 29 consecutive patients (14 females, 15 males; median age: 30.0 years, range: 18–76 undergoing temporary fecal diversion for colorectal (n=14, ileal (n=4, and/or perianal Crohn’s disease (n=22. Follow-up was in median 33.0 (3–103 months. Response to fecal diversion, rate of stoma reversal, and relapse rate after stoma reversal were recorded. Results. The response to temporary fecal diversion was complete remission in 4/29 (13.8%, partial remission in 12/29 (41.4%, no change in 7/29 (24.1%, and progress in 6/29 (20.7%. Stoma reversal was performed in 19 out of 25 patients (76% available for follow-up. Of these, the majority (15/19, 78.9% needed further surgical therapies for a relapse of the same pathology previously leading to temporary fecal diversion, including colorectal resections (10/19, 52.6% and creation of a definitive stoma (7/19, 36.8%. At the end of follow-up, only 4/25 patients (16% had a stable course without the need for further definitive surgery. Conclusion. Temporary fecal diversion can induce remission in otherwise refractory colorectal or perianal Crohn’s disease, but the chance of enduring remission after stoma reversal is low.

    Junctional ectopic tachycardia (JET) is a postoperative complication with a mortality rate of up to 14% after surgery for congenital heart disease. This study evaluated the risk factors of JET and explored the association of postoperative temporary third degree atrioventricular (AV) block and the occurrence of JET. Data were collected retrospectively from 1158 patients who underwent surgery for congenital heart disease. The overall incidence of JET was 2.8%. Temporary third degree AV block occurred in 1.6% of cases. Permanent third degree AV block requiring pacemaker implantation occurred in 1% of cases. In all, 56% of patients with JET had temporary AV block (P < 0.001), whereas no case of postoperative JET was reported in patients with permanent AV block (P = 0.56). temporary third degree AV block did not suffer from JET. A correlation between temporary third degree AV block and postoperative JET could be observed. The risk factors identified for JET include younger age groups at the time of surgery, longer aortic cross clamping time and surgical procedures in proximity to the AV node

    In critically ill patients, gastrointestinal function plays an important role in multiple organ dysfunction syndrome. Patients suffering from acute lower gastrointestinal dysfunction need to be performed a temporary fecal diversion after the failure of conservative treatment. This study aims to determine which type of fecal diversion is associated with better clinical outcomes in critically ill patients. Data of critically ill patients requiring surgical decompression following acute lower gastrointestinal dysfunction between January 2008 and June 2013 were retrospectively analyzed. Comparison was made between ileostomy group and colostomy group regarding the stoma-related complications and the recovery after stoma creation. 63 patients consisted of temporary ileostomy group (n = 35) and temporary colostomy group (n = 28) were included in this study. First bowel movement and length of enteral nutrition intolerance after fecal diversion were both significantly shorter in the ileostomy group than in the colostomy group (1.70 ± 0.95 vs. 3.04 ± 1.40; p colostomy group. Both procedures provide an effective defunctioning of the distant gastrointestinal tract with a low complication incidence. We prefer a temporary ileostomy to temporary colostomy for acute lower gastrointestinal dysfunction in critically ill patients.

    When decommissioning a nuclear power plant, it is difficult to make an appropriate plan to ensure sufficient space for temporary placement and conveyance operations of dismantling targets. This paper describes a system to support temporary placement and conveyance operations using augmented reality (AR). The system employs a laser range scanner to measure the three-dimensional (3D) information of the environment and a dismantling target to produce 3D surface polygon models. Then, the operator simulates temporary placement and conveyance operations using the system by manipulating the obtained 3D model of the dismantling target in the work field. Referring to the obtained 3D model of the environment, a possible collision between the dismantling target and the environment is detectable. Using AR, the collision position is presented intuitively. After field workers evaluated this system, the authors concluded that the system is feasible and acceptable to verify whether spaces for passage and temporary storage are sufficient for temporary placement and conveyance operations. For practical use in the future, some new functions must be added to improve the system. For example, it must be possible for multiple workers to use the system simultaneously by sharing the view of dismantling work.

    Full Text Available Objectives The purpose of this study was to evaluate the microleakage of 4 temporary materials in teeth with Class II-type endodontic access preparations by using a glucose penetration model. Materials and Methods Glucose reaction test was performed to rule out the presence of any reaction between glucose and temporary material. Class II-type endodontic access preparations were made in extracted human premolars with a single root (n = 10. Each experimental group was restored with Caviton (GC, Spacer (Vericom, IRM (Dentsply-Caulk, or Fuji II(GC. Microleakage of four materials used as temporary restorative materials was evaluated by using a glucose penetration model. Data were analyzed by the one-way analysis of variance followed by a multiple-comparison Tukey test. The interface between materials and tooth were examined under a scanning electron microscope (SEM. Results There was no significant reaction between glucose and temporary materials used in this study. Microleakage was significantly lower for Caviton and Spacer than for Fuji II and IRM. SEM observation showed more intimate adaptation of tooth-restoration interfaces in Caviton and Spacer than in IRM and Fuji II. Conclusions Compared to IRM and Fuji II, Caviton and Spacer can be considered better temporary sealing materials in Class II-type endodontic access cavities.

    In accordance with the Low-Level Radioactive Waste Policy Amendments Act of 1985, States will become responsible for managing low-level radioactive waste, including mixed waste, generated within their borders as of January 1, 1993. In response to this mandate, many States and compact regions have made substantial progress toward establishing new disposal capacity for these wastes. While this progress is noteworthy, many circumstances can adversely affect States' abilities to meet the 1993 deadline, and many States have indicated that they are considering other waste management options in order to fulfill their responsibilities beyond 1992. Among the options that States are considering for the interim management of low- level radioactive waste is temporary storage. Temporary storage may be either short term or long term and may be at a centralized temporary storage facility provided by the State or a contractor, or may be at the point of generation or collection. Whether States choose to establish a centralized temporary storage facility or choose to rely on generators or brokers to provide additional and problem areas that must be addressed and resolved. Areas with many potential issues associated with the temporary storage of waste include: regulations, legislation, and policy and implementation guidance; economics; public participation; siting, design, and construction; operations; and closure and decommissioning

    Although our understanding of environmental risk assessment in temporary wetlands has been improved by the use of multi-species toxicity testing, we still know little of how landscape variables mediate the strength of, and recovery from, anthropogenic stress in such ecosystems. To bridge this research gap, we provide a theoretical framework of the response of temporary wetlands to anthropogenic disturbance along a habitat-isolation continuum based on island biogeography theory, landscape ecology and dispersal and colonization strategies of temporary wetland organisms. - Environmental risk assessment in temporary wetlands may benefit from consideration of island biogeography theory and landscape structure

  7. Effect of joint mechanism on vehicle redirectional capability of water-filled road safety barrier systems.

    Portable water-filled barriers (PWFBs) are roadside appurtenances that prevent vehicles from penetrating into temporary construction zones on roadways. PWFBs are required to satisfy the strict regulations for vehicle re-direction in tests. However, many of the current PWFBs fail to re-direct the vehicle at high speeds due to the inability of the joints to provide appropriate stiffness. The joint mechanism hence plays a crucial role in the performance of a PWFB system at high speed impacts. This paper investigates the desired features of the joint mechanism in a PWFB system that can re-direct vehicles at high speeds, while limiting the lateral displacement to acceptable limits. A rectangular "wall" representative of a 30m long barrier system was modeled and a novel method of joining adjacent road barriers was introduced through appropriate pin-joint connections. The impact response of the barrier "wall" and the vehicle was obtained and the results show that a rotational stiffness of 3000kNm/rad at the joints seems to provide the desired features of the PWFB system to re-direct impacting vehicles and restrict the lateral deflection. These research findings will be useful to safety engineers and road barrier designers in developing a new generation of PWFBs for increased road safety. Copyright © 2014 Elsevier Ltd.

    The evolution in flat and curved space-time of quantum fields in theories with relative flat potential and its consequences are considered. It is shown that bubble nucleation, a quantum mechanical tunnelling process, may occur in flat space-time, having a bounce solution, even if V(phi) has no barrier. It is shown that bubble nucleation can also occur in curved space-time even though there is no bounce solution in the standard formalism for the bubble nucleation rate in curved space-time. Additionally, bubbles can nucleate during the slow rolling period on the potential in flat and curved space-time, in this case also there is no bounce solution. It is known in the new inflationary scenario that energy density perturbations caused by quantum fluctuations of the scalar field can satisfy the presently observed bounds on density perturbations. Bubble nucleation during the slow rolling period also gives rise to density perturbations. For a model potential density perturbations by bubbles are calculated at the horizon reentering. By applying the bound from the almost isotropic microwave black body radiation on these density perturbations, a constraint on the model potential is obtained. Finally, some further implications on the galaxy formation and applications in more realistic potential are discussed

    Engineered barrier development was carried out into the three research fields : waste form, disposal container, and buffer. The waste form field dealt with long-term leaching tests with borosilicate waste glasses surrounded by compacted bentonite. The leach rate decreased with increasing time, and was higher for the waste specimen rich in U and Na. In the container field, preliminary concepts of disposal containers were recommended by conducting structural analysis, thermal analysis, and shielding analysis, and major properties of stainless steel, copper, and titanium as a container material were surveyed. The sensitization degrees of SUS 316 and316L were lower than those of SUS 304 and 304L, respectively. The crevice corrosion of sensitized stainless steel was sensitive to the content of salt. Researches into the buffer included establishment of its performance criteria followed by investigating major properties of buffer using potential material in Korea. Experiments were made for measuring hydraulic conductivities, swelling properties, mechanical properties, thermal conductivities, pore-water chemistry properties, and adsorption properties was also investigated.

    As an important problem in acoustics, sound insulation finds applications in a great variety of situations. In the existing schemes, however, there has always been a trade-off between the thinness of sound-insulating devices and their ventilating capabilities, limiting their potentials in the control of low-frequency sound in high ventilation environments. Here, we design and experimentally implement an omnidirectional acoustic barrier with a planar profile, subwavelength thickness ( 0.18 λ ), yet high ventilation. The proposed mechanism is based on the interference between the resonant scattering of discrete states and the background scattering of continuous states which induces a Fano-like asymmetric transmission profile. Benefitting from the binary-structured design of the coiled unit and hollow pipe, it maximally simplifies the design and fabrication while ensuring the ventilation for all the non-resonant units with open tubes. The simulated and measured results agree well, showing the effectiveness of our proposed mechanism to block low frequency sound coming from various directions while allowing 63% of the air flow to pass. We anticipate our design to open routes to design sound insulators and to enable applications in traditionally unattainable cases such as those calling for noise reduction and cooling simultaneously.

    1991-07-01

    Previous investigations of the effects of neutralization and reduction on uranium mill tailings pore fluids by the Technical Support Contractor indicated that arsenic, selenium, and molybdenum continue to remain in solution in all but reducing conditions. These hazardous constituents are present in groundwaters as oxyanions and, therefore, are not expected to be removed by adsorption into clays and most other soil constituents. It was decided to investigate the attenuation capacity of two commonly available crystalline iron oxides, taconite and scoria, and a zeolite, a network aluminosilicate with a cage structure. Columns of the candidate materials were exposed to solutions of individual constituents, including arsenic, molybdenum, selenium, and, uranium, and to the spiked tailings pore fluid from the Bodo Canyon disposal cell near Durango, Colorado. In addition to the single material columns, a homogeneous blend of the three materials and layers of the materials were exposed to spiked tailings pore fluids. The results of these experiments indicate that with the exception of molybdenum, the constituents of concern are attenuated by the taconite; however, they are not sufficiently attenuated to meet the groundwater protection standards applicable to the UMTRA Project. Therefore, the candidate barrier materials did not prove to be useful to the UMTRA Project for the cleanup of groundwaters

    Since the Fukushima Daiichi nuclear power plant accident caused by the Tohoku Region Pacific Coast Earthquake on March 11, 2011, decontamination work has been conducted in the surrounding environment within the Fukushima prefecture. Removed contaminants including soil, grass and trees are to be stored safely at temporary storage facilities for up to three years, after which they will be transferred to a planned interim storage facility. The decontamination pilot project was carried out in both the restricted and planned evacuation areas in order to assess decontamination methods and demonstrate measures for radiation protection of workers. Fourteen temporary storage facilities of different technical specifications were designed and constructed under various topographic conditions and land use. In order to support the design, construction and monitoring of temporary storage facilities for removed contaminants during the full-scale decontamination within the prefecture of Fukushima, technical know-how obtained during the decontamination pilot project has been identified and summarized in this paper.

  17. Temporary agency work, migration and the crisis in Greece: labour market segmentation intensified.

    Science.gov (United States)

    Maroukis, Thanos

    2016-05-01

    This article focuses on the under-researched temporary agency employment in Greece. It shows that the development of the temporary employment agency sector has gone hand in hand with the flow of undocumented and exploitable migrant labour in Greece over the past 25 years, reflecting the segmentation of the Greek labour market along ethnic lines. Using empirical research evidence on the operation of temporary employment agencies in the Greek hospitality and health care sectors, the article highlights the precarious or even illicit nature of agency employment in a context in which labour outsourcing and flexible employment are promoted by policy-makers. Last but not least, it suggests that the segmented landscape of the Greek labour market has become more complex during the economic crisis, with more and more Greeks drawn to agency-mediated precarious employment.

  20. Tritium/hydrogen barrier development

    Hollenberg, G.W.; Simonen, E.P.; Kalinen, G.; Terlain, A.

    1994-06-01

    A review of hydrogen permeation barriers that can be applied to structural metals used in fusion power plants is presented. Both implanted and chemically available hydrogen isotopes must be controlled in fusion plants. The need for permeation barriers appears strongest in Li17-Pb blanket designs, although barriers also appear necessary for other blanket and coolant systems. Barriers that provide greater than a 1000 fold reduction in the permeation of structural metals are desired. In laboratory experiments, aluminide and titanium ceramic coatings provide permeation reduction factors, PRFS, from 1000 to over 100,000 with a wide range of scatter. The rate-controlling mechanism for hydrogen permeation through these barriers may be related to the number and type of defects in the barriers. Although these barriers appear robust and resistant to liquid metal corrosion, irradiation tests which simulate blanket environments result in very low PRFs in comparison to laboratory experiments, i.e., <150. It is anticipated from fundamental research activities that the REID enhancement of hydrogen diffusion in oxides may contribute to the lower permeation reduction factors during in-reactor experiments

    Many streams in the Mediterranean Basin have temporary flow regimes. While timing for seasonal drought is predictable, they undergo strong inter-annual variability in flow intensity. This high hydrological variability and associated ecological responses challenge the ecological status assessment of temporary streams, particularly when setting reference conditions. This study examined the effects of flow connectivity in aquatic macroinvertebrates from seven reference temporary streams across the Mediterranean Basin where hydrological variability and flow conditions are well studied. We tested for the effect of flow cessation on two streamflow indices and on community composition, and, by performing random forest and classification tree analyses we identified important biological predictors for classifying the aquatic state either as flowing or disconnected pools. Flow cessation was critical for one of the streamflow indices studied and for community composition. Macroinvertebrate families found to be important for classifying the aquatic state were Hydrophilidae, Simuliidae, Hydropsychidae, Planorbiidae, Heptageniidae and Gerridae. For biological traits, trait categories associated to feeding habits, food, locomotion and substrate relation were the most important and provided more accurate predictions compared to taxonomy. A combination of selected metrics and associated thresholds based on the most important biological predictors (i.e. Bio-AS Tool) were proposed in order to assess the aquatic state in reference temporary streams, especially in the absence of hydrological data. Although further development is needed, the tool can be of particular interest for monitoring, restoration, and conservation purposes, representing an important step towards an adequate management of temporary rivers not only in the Mediterranean Basin but also in other regions vulnerable to the effects of climate change. - Highlights: • The effect of flow connectivity on macroinvertebrate

    2015-01-01

    Temporary agency workers are often portrayed as peripheral workers in organisations. Hence, they present a compelling illustration of the established-outsider theory of Elias and Scotson. According to this theory, differences in social cohesion, group charisma, and power of the members of subgroups within social entities can lead to an established-outsider figuration between these subgroups, which is maintained by processes of stigmatisation and exclusion. Applying a narrative approach, we fo...

  10. Lessons Learned from Missing Flooding Barriers Operating Experience

    International Nuclear Information System (INIS)

    Simic, Z.; Veira, M. P.

    2016-01-01

    Flooding hazard is highly significant for nuclear power plant safety because of its potential for common cause impact on safety related systems, and because operating experience reviews regularly identify flooding as a cause of concern. Source of the flooding could be external (location) or internal (plant design). The amount of flooding water could vary but even small amount might suffice to affect redundant trains of safety related systems for power supply and cooling. The protection from the flooding is related to the design-basis flood level (DBFL) and it consists of three elements: structural, organizational and accessibility. Determination of the DBFL is critical, as Fukushima Daiichi accident terribly proved. However, as the topic of flooding is very broad, the scope of this paper is focused only on the issues related to the missing flood barriers. Structural measures are physically preventing flooding water to reach or damage safety related system, and they could be permanent or temporary. For temporary measures it is important to have necessary material, equipment and organizational capacity for the timely implementation. Maintenance is important for permanent protection and periodical review is important for assuring readiness and feasibility of temporary flooding protection. Final flooding protection element is assured accessibility to safety related systems during the flooding. Appropriate flooding protection is based on the right implementation of design requirements, proper maintenance and periodic reviews. Operating experience is constantly proving how numerous water sources and systems interactions make flooding protection challenging. This paper is presenting recent related operating experience feedback involving equipment, procedures and analysis. Most frequent deficiencies are: inadequate, degraded or missing seals that would allow floodwaters into safety related spaces. Procedures are inadequate typically because they underestimate necessary

    We have studied fusion barrier characteristics of actinide compound nuclei with atomic number range 89 ≤ Z ≤ 103 for all projectile target combinations. After the calculation of fusion barrier heights and positions, we have searched for their parameterization. We have achieved the empirical formula for fusion barrier heights (VB), positions (RB), curvature of the inverted parabola (ħω) of actinide compound nuclei with atomic number range 89 ≤ Z ≤ 103 for all projectile target combinations (6 projectile target combinations. The values produced by the present formula are also compared with experiments. The present pocket formula produces fusion barrier characteristics of actinides with the simple inputs of mass number (A) and atomic number (Z) of projectile-targets.

    International Nuclear Information System (INIS)

    Ida, Katsumi

    1998-01-01

    Experiments on the transport barrier in Helical plasmas are reviewed. There are two mechanisms of transport improvement, that results in the formation of the transport barrier. One is the improvement of neoclassical transport by reducing the ripple loss with radial electric field, which exist only in helical plasma. The other is the improvement of anomalous transport due to the suppression of fluctuations associated with a radial electric field shear both in tokamak and helical plasma. The formation of the transport barrier can be triggered by the radial electric field shear associated with the transition of the radial electric field (L/H transition or ion-electron root transition) or the peaked density or the optimization of magnetic field shear. The mechanisms of transport barrier formation are also discussed. (author). 60 refs

    1989-06-01

    This report summarises the current state of research relevant to assessing the performance of engineered barriers made of steel and concrete in radioactive waste repositories. The objective of these barriers is to contain substantially the radionuclides within them by providing both physical and chemical impediment to their release. The physical barriers are of most value for highly soluble isotopes with relatively short half-lives (eg 137 Cs), since they can provide a measure of containment until a large fraction of the activity has decayed. In addition they can facilitate retrievability for some period after disposal. The chemical barriers operate by beneficial conditioning of the near field groundwater and providing sites for sorption of radionuclides. Both of these reduce the aqueous concentration of radionuclides in the near field. (author)

  15. Numerical simulation of flood barriers

    Science.gov (United States)

    Srb, Pavel; Petrů, Michal; Kulhavý, Petr

    This paper deals with testing and numerical simulating of flood barriers. The Czech Republic has been hit by several very devastating floods in past years. These floods caused several dozens of causalities and property damage reached billions of Euros. The development of flood measures is very important, especially for the reduction the number of casualties and the amount of property damage. The aim of flood control measures is the detention of water outside populated areas and drainage of water from populated areas as soon as possible. For new flood barrier design it is very important to know its behaviour in case of a real flood. During the development of the barrier several standardized tests have to be carried out. Based on the results from these tests numerical simulation was compiled using Abaqus software and some analyses were carried out. Based on these numerical simulations it will be possible to predict the behaviour of barriers and thus improve their design.

  13. Material Barriers to Diffusive Mixing

    Science.gov (United States)

    Haller, George; Karrasch, Daniel

    2017-11-01

    Transport barriers, as zero-flux surfaces, are ill-defined in purely advective mixing in which the flux of any passive scalar is zero through all material surfaces. For this reason, Lagrangian Coherent Structures (LCSs) have been argued to play the role of mixing barriers as most repelling, attracting or shearing material lines. These three kinematic concepts, however, can also be defined in different ways, both within rigorous mathematical treatments and within the realm of heuristic diagnostics. This has lead to a an ever-growing number of different LCS methods, each generally identifying different objects as transport barriers. In this talk, we examine which of these methods have actual relevance for diffusive transport barriers. The latter barriers are arguably the practically relevant inhibitors in the mixing of physically relevant tracers, such as temperature, salinity, vorticity or potential vorticity. We demonstrate the role of the most effective diffusion barriers in analytical examples and observational data. Supported in part by the DFG Priority Program on Turbulent Superstructures.

  14. Economic alternatives for containment barriers

    International Nuclear Information System (INIS)

    Nicholson, P.J.; Jasperse, B.H.; Fisher, M.J.

    1997-01-01

    Fixation, barriers, and containment of existing landfills and other disposal areas are often performed by insitu auger type soil mixing and jet grouting. Cement or other chemical reagents are mixed with soil to form both vertical and horizontal barriers. Immobilization of contaminants can be economically achieved by mixing soil and the contaminants with reagents that solidify or stabilize the contaminated area. Developed in Japan, and relatively new to the United States, the first large scale application was for a vertical barrier at the Jackson Lake Dam project in 1986. This technology has grown in both the civil and environmental field since. The paper describes current United States practice for Deep Soil Mixing (over 12 meters in depth), and Shallow Soil Mixing for vertical barriers and stabilization/solidification, and Jet Grouting for horizontal and vertical barriers. Creating very low permeability barriers at depth with minimal surface return often makes these techniques economical when compared to slurry trenches. The paper will discuss equipment, materials, soil and strength parameters, and quality control

  15. Air barrier systems: Construction applications

    Energy Technology Data Exchange (ETDEWEB)

    Perrault, J.C

    1989-01-01

    An examination is presented of how ordinary building materials can be used in an innovative manner to design, detail, and construct effective air barrier systems for common types of walls. For residential construction, the air drywall approach uses the interior gypsum board as the main component of the wall air barrier system. Joints between the gypsum board and adjacent materials or assemblies are sealed by gaskets. In commercial construction, two different techniques are employed for using gypsum board as air barrier material: the accessible drywall and non-accessible drywall approaches. The former is similar to the air drywall approach except that high performance sealants are used instead of gaskets. In the latter approach, exterior drywall sheathing is the main component of the air barrier system; joints between boards are taped and joints between boards and other components are sealed using elastomeric membrane strips. For various types of commercial and institutional buildings, metal air barrier systems are widely used and include pre-engineered curtain walls or sheet metal walls. Masonry wall systems are regarded as still the most durable, fireproof, and soundproof wall type available but an effective air barrier system has typically been difficult to implement. Factory-made elastomeric membranes offer the potential to provide airtightness to masonry walls. These membranes are applied on the entire masonry wall surface and are used to make airtight connections with other building components. Two types of product are available: thermofusible and peel-and-stick membranes. 5 figs.

    2014-04-01

    In employing the adopted methodology of research, the paper commences by a literature review which aims to set the basic terms and concepts. Consecutively, the paper sets the basic foundations to the provision, design and construction of temporary dwellings. The discussion widens in scope to analyze the qualitative aspects related to the management of temporary dwellings. This part constitutes the basic guidelines which support the following discussions made in the paper. As the subjects keep on unfolding, the concept of contextualization is elaborated with the issue of ‘sensitivity’ to local conditions and circumstances as a prime focus. The paper finally proceeds to analyzing a number of important qualitative aspects related to the design and construction of temporary dwellings with a special focus on temporary houses. The discussion is emphasized through examining several examples to clarify the various needs and implications of the qualitative aspects under investigation. The overall research outcome of the paper is expressed in a number of findings and recommendations in correspondence to the paper structure.

  11. Zooplankton resting egg banks in permanent and temporary tropical aquatic systems

    Directory of Open Access Journals (Sweden)

    Luciana Rabelo Araújo

    Full Text Available AIM: We evaluated zooplankton resting egg banks and active communities in five coastal lagoons and in five temporary pools, aiming to compare the active and the dormant communities in such environments. As they differ in hydroperiod, we expected that pools present richer resting egg banks in comparison to those found in lagoons. METHODS: Zooplankton community was sampled twice in 2006 (lagoons and in 2010 (pools and resting egg banks were sampled once in December 2007 (lagoons and in May 2010 (pools. Resting eggs were isolated from the sediment by applying the sugar flotation method. RESULTS: In opposition to our expectation, species richness in the resting egg banks of pools did not differ from those of lagoons. Additionally, no difference was found between the active and the dormant zooplankton communities in each water body for both temporary and permanent environments. However, similarity between active and dormant communities was greater in permanent environments than it was in temporary environments. CONCLUSIONS: It seems that the diapause strategy observed in certain tropical zooplankton populations cannot be predicted based on the awareness of the environment type (permanent or temporary, since hatching cues may be species-specific.

  12. Temporary Stabilization with External Fixator in 'Tripolar' Configuration in Two Steps Treatment of Tibial Pilon Fractures.

    Daghino, Walter; Messina, Marco; Filipponi, Marco; Alessandro, Massè

    2016-01-01

    The tibial pilon fractures represent a complex therapeutic problem for the orthopedic surgeon, given the frequent complications and outcomes disabling. The recent medical literature indicates that the best strategy to reduce amount of complications in tibial pilon fractures is two-stages procedure. We describe our experience in the primary stabilization of these fractures. We treated 36 cases with temporary external fixation in a simple configuration, called "tripolar": this is an essential structure (only three screws and three rods), that is possible to perform even without the availability of X-rays and with simple anesthesia or sedation. We found a sufficient mechanical stability for the nursing post-operative, in absence of intraoperative and postoperative problems. The time between trauma and temporary stabilization ranged between 3 and 144 hours; surgical average time was 8.4 minutes. Definitive treatment was carried out with a delay of a minimum of 4 and a maximum of 15 days from the temporary stabilization, always without problems, both in case of ORIF (open reduction, internal fixation) or circular external fixation. Temporary stabilization with external fixator in 'tripolar' configuration seems to be the most effective strategy in two steps treatment of tibial pilon fractures. These preliminary encouraging results must be confirmed by further studies with more cases.

  13. Associations between temporary employment and occupational injury: what are the mechanisms?

    2006-06-01

    To determine whether observed higher risks of occupational injury among temporary workers are due to exposure to hazardous working conditions and/or to lack of job experience level. Data systematically recorded for 2000 and 2001 by the Spanish Ministry of Labour and Social Affairs on fatal and non-fatal traumatic occupational injuries were examined by type of employment and type of accident, while adjusting for gender, age, occupation, and length of employment in the company. In the study period there were 1500 fatal and 1 806 532 non-fatal traumatic occupational injuries that occurred at the workplace. Incidence rates and rate ratios (RR) were estimated using Poisson regression models. Temporary workers showed a rate ratio of 2.94 for non-fatal occupational injuries (95% CI 2.40 to 3.61) and 2.54 for fatal occupational injuries (95% CI 1.88 to 3.42). When these associations were adjusted by gender, age, occupation, and especially length of employment, they loose statistic significance: 1.05 (95% CI 0.97 to 1.12) for non-fatal and 1.07 (95% CI 0.91 to 1.26) for fatal. Lower job experience and knowledge of workplace hazards, measured by length of employment, is a possible mechanism to explain the consistent association between temporary workers and occupational injury. The role of working conditions associated with temporary jobs should be assessed more specifically.

  17. Efficacy of balloon temporary occlusion and intraoperative DSA in surgically difficult aneurysm

    International Nuclear Information System (INIS)

    Ezura, Masayuki; Mizoi, Kazuo; Yoshimoto, Takashi; Takahashi, Akira.

    1993-01-01

    A digital subtraction angiographic (DSA) apparatus has been installed in one of our operating rooms since April 1987. We performed intraoperative DSA in 42 aneurysmal surgeries in 38 patients and balloon temporary occlusion in 33 surgeries. The aneurysm was on an internal carotid artery in 26 cases and on the vertebro-basilar system in 16. A heparin-coated catheter (Anthron, Toray, Tokyo), 6 french in diameter, was inserted transfemorally and was put in a parent artery under general anesthesia. A balloon was temporarily inflated to determine inflation volume. The balloon catheter was soon deflated and was drawn back into the introducing catheter to avoid developing microembolus. The patients were not systemically heparinized but the introducing catheters were slowly flushed with heparinized saline during operation. Then a craniotomy was carried out. Next DSA was performed when temporary occlusion or confirmation of clipping was necessary. In cases of balloon temporary occlusion, the operating field was not obstructed as it is when a temporary clip is used, despite adequate flow reduction of the parent artery. After DSA for confirmation of clipping adjustment of it was performed in 12 cases out of 42. No complications occurred due to use of an introducing or a balloon catheter. We conclude that combined intravascular and neurosurgical approach, particularly for the large aneurysms with the difficulty of proximal control, can be a useful method of treatment. (author)

  18. Is temporary employment related to health status? Analysis of the Northern Swedish Cohort.

    Science.gov (United States)

    Waenerlund, Anna-Karin; Virtanen, Pekka; Hammarström, Anne

    2011-07-01

    The aim of this study was to investigate whether temporary employment was related to non-optimal self-rated health and psychological distress at age 42 after adjustment for the same indicators at age 30, and to analyze the effects of job insecurity, low cash margin and high job strain on this relationship. A subcohort of the Northern Swedish Cohort that was employed at the 2007 follow-up survey (n = 907, response rate of 94%) was analyzed using data from 1995 and 2007 questionnaires. Temporary employees had a higher risk of both non-optimal self-rated health and psychological distress. After adjustment for non-optimal self-rated health at age 30 and psychological distress at age 30 as well as for sociodemographic variables, the odds ratios decreased but remained significant. However, after adjustment for job insecurity, high job strain and low cash margin the odds ratio dropped for non-optimal self-rated health but remained significant for psychological distress. Temporary employment may have adverse effects on self-rated health and psychological health after adjustment for previous health status and sociodemographic variables. Our findings indicate that low cash margin and job insecurity may partially mediate the association between temporary employment and health status.

    Full Text Available Summary: The aim of the present investigation was usage of medicamental paste with antibacterial and regeneration action for temporary placement in the treatment of chronic apical periodontitis. Materials and method: The medicamental paste for temporary placement of root canals consists of a mixture of metronidazole, Enterosgel (Silm and Alflutop (Biotehnos S.A., Romania. Thë paste was used for the treatment of 30 teeth with chronic apical periodontitis. Final obturation of the root canals was performed with gutta percha cones and sealer. The efficiency of the treatment was appreciated after examination on the basis of clinical and radiographic findings. Results: During the treatment of the 30 teeth, no exacerbations of the pathological process were recorded. Pain after obturation of the root canals was revealed in only 6 (20% of the treated teeth. No pain, pathologic changes of gingiva, good mastication efficiency in all teeth after treatment were revealed. Conclusions: The high clinical efficiency of the medicamental paste with antibacterial and regeneration action at the level of temporary root canals placement in the treatment of chronic apical periodontitis was shown. Keywords: chronic apical periodontitis, medicamental paste for temporary root canals placement, metronidazole, Enterosgel (Silm and Alflutop (Biotehnos S.A., Romania

  1. Long-term follow-up of children thought to have temporary brittle bone disease

    Directory of Open Access Journals (Sweden)

    Paterson CR

    2011-06-01

    Full Text Available Colin R Paterson1, Elizabeth A Monk21Department of Medicine (retired, 2School of Accounting and Finance, University of Dundee, Dundee, ScotlandBackground: In addition to nonaccidental injury, a variety of bone disorders may underlie the finding of unexplained fractures in young children. One controversial postulated cause is temporary brittle bone disease, first described in 1990.Methods: Eighty-five patients with fractures showing clinical and radiological features of temporary brittle bone disease were the subject of judicial hearings to determine whether it was appropriate for them to return home. Sixty-three patients did, and follow-up information was available for 61 of these. The mean follow-up period was 6.9 years (range 1–17, median 6.Results: We found that none of the children had sustained any further injuries that were thought to represent nonaccidental injury; no child was re-removed from home. Three children had fractures. In each case there was general agreement that the fractures were accidental. Had the original fractures in these children been the result of nonaccidental injury, it would have been severe and repeated; the average number of fractures was 9.1.Conclusion: The fact that no subsequent suspicious injuries took place after return home is consistent with the view that the fractures were unlikely to have been caused by nonaccidental injury, and that temporary brittle bone disease is a distinctive and identifiable disorder.Keywords: fractures, osteogenesis imperfecta, temporary brittle bone disease, nonaccidental injury

    Disasters are recurring to global problems, which results in homelessness. The affected region had economical, environmental and social problems as well. In relief and reconstruction phases, the need for integrated management appeared in order to use the national sources actively and productively. Especially housing implementations had an important role for future development of the affected region. For accelerating the reconstruction of the region and forming a sustainable community, which maintains itself socially, environmentally and economically over time; energy usage for construction should be kept to a minimum. Past research in Turkey shows that the cost of temporary houses (to be used as the short term shelter) had a ratio of 10-15% of the total expenses of whole construction activity. For saving money and protecting the environment and conserving scarce resources, the affected region must consider the option of temporary houses to meet their short and long-term need during the reconstruction process. After the end of usage, temporary houses should be able to be re-used for the same or new function. This study is a test of re-design and re-use of a temporary housing site; by using recycled materials, minimum energy and voluntary participation so that this site can finally become a permanent housing site.

    Several techniques for temporary abdominal closure have been developed. We systematically review the literature on temporary abdominal closure to ascertain whether the method can be tailored to the indication. Medline, Embase, the Cochrane Central Register of Controlled Trials and relevant meeting abstracts until December 2009 were searched using the following headings: open abdomen, laparostomy, VAC (vacuum assisted closure), TNP (topical negative pressure), fascial closure, temporary abdominal closure, fascial dehiscence and deep wound dehiscence. The data were analysed by closure technique and aetiology. The primary end-points included delayed fascial closure and in-hospital mortality. The secondary end-points were intra-abdominal complications. The search identified 106 papers for inclusion. The techniques described were VAC (38 series), mesh/sheet (30 series), packing (15 series), Wittmann patch (eight series), Bogotá bag (six series), dynamic retention sutures (three series), zipper (15 series), skin only and locking device (one series each). The highest facial closure rates were seen with the Wittmann patch (78%), dynamic retention sutures (71%) and VAC (61%). Temporary abdominal closure has evolved from simple packing to VAC based systems. In the absence of sepsis Wittmann patch and VAC offered the best outcome. In its presence VAC had the highest delayed primary closure and the lowest mortality rates. However, due to data heterogeneity only limited conclusions can be drawn from this analysis. © 2012 The Authors.

  15. Reciprocity of temporary and permanent workers: an exploratory study in an industrial company.

    Lopes, Silvia; Chambel, Maria José

    2012-11-01

    The increasing use of temporary work prompts the need to understand to what degree workers with this type of contract differ from permanent workers as to the relationship they establish with the organization they work for. This study used a sample of temporary workers (N = 78) and permanent workers (N = 196) within the same company of electronics in Portugal. The results show that, regardless of the type of contract, the perception of human resource practices was related to the perception of psychological contract fulfillment by the company. Additionally and according to the norm of reciprocity, we verified that when workers thought the company was fulfilling its obligations they responded favorably showing more affective commitment towards the company. However, we found differences between these two groups of workers: for the permanent performance appraisal, training and rewards were human resources practices that were significantly related to psychological contract fulfillment, while for the temporary ones there weren't any specific practices that had a significant relationship with that variable. The practical implications of these findings for the management of temporary workers are discussed.

  16. Influence of Screw Length and Bone Thickness on the Stability of Temporary Implants

    Directory of Open Access Journals (Sweden)

    Daniel Jogaib Fernandes

    2015-09-01

    Full Text Available The purpose of this work was to study the influence of screw length and bone thickness on the stability of temporary implants. A total of 96 self-drilling temporary screws with two different lengths were inserted into polyurethane blocks (n = 66, bovine femurs (n = 18 and rabbit tibia (n = 12 with different cortical thicknesses (1 to 8 mm. Screws insertion in polyurethane blocks was assisted by a universal testing machine, torque peaks were collected by a digital torquemeter and bone thickness was monitored by micro-CT. The results showed that the insertion torque was significantly increased with the thickness of cortical bone from polyurethane (p < 0.0001, bovine (p = 0.0035 and rabbit (p < 0.05 sources. Cancellous bone improved significantly the mechanical implant stability. Insertion torque and insertion strength was successfully moduled by equations, based on the cortical/cancellous bone behavior. Based on the results, insertion torque and bone strength can be estimate in order to prevent failure of the cortical layer during temporary screw placement. The stability provided by a cortical thickness of 2 or 1 mm coupled to cancellous bone was deemed sufficient for temporary implants stability.

  20. Changes in Temporary Disability Reporting Following the Implementation of the Army Medical Readiness Transformation.

    Science.gov (United States)

    Sapp, Jason E; Cody, Matthew J; Douglas, Kevin M

    2018-02-07

    In November 2014, the U.S. Army held a readiness summit to address concerns about the accuracy of medical reporting systems. At the time, soldiers on temporary disability were tracked as a medical readiness classification (MRC) 3A or 3B. MRC 3A soldiers had a medical condition with recovery expected within 30 d and MRC 3B soldiers were expected to take longer than 30 d to recover. Both groups were considered "non-available" and presumably non-deployable. Starting June 1, 2016, with the implementation of the Army Medical Readiness Transformation, soldiers on temporary disability longer than 14 d began to be reported as MRC 3s and are considered "non-deployable." The purpose of this study is to compare the number of soldiers on temporary disability previously reported as MRC 3A and 3B to the number listed as MRC 3 under the new reporting system for a light infantry brigade and to quantify the types and relative percentage of medical conditions leading to temporary disability under the new system. This cross-sectional analysis was conducted between January 1 and December 31, 2016 at Fort Carson, Colorado and included all soldiers assigned to Second Brigade, Fourth Infantry Division. We calculated the average number and proportion of soldiers on temporary disability at any one time for the period prior to implementation of the new reporting system (January 1 through May 31, 2016) and compared this to the period after implementation on June 1, 2016. The difference between the two independent proportions was calculated along with the lower and upper limits of the 95% confidence interval for the difference. Between January 1 and May 31, 2016, the average number of soldiers on temporary disability at any one time was 186, accounting for 4.3% of the authorized unit strength. After June 1, 2016, the average number increased to 244 or 5.7%. The difference in the proportion of temporary profiles was 1.4% (95% confidence interval 0.43-2.3%). From June 1 through December 31

    Many streams in the Mediterranean Basin have temporary flow regimes. While timing for seasonal drought is predictable, they undergo strong inter-annual variability in flow intensity. This high hydrological variability and associated ecological responses challenge the ecological status assessment of temporary streams, particularly when setting reference conditions. This study examined the effects of flow connectivity in aquatic macroinvertebrates from seven reference temporary streams across the Mediterranean Basin where hydrological variability and flow conditions are well studied. We tested for the effect of flow cessation on two streamflow indices and on community composition, and, by performing random forest and classification tree analyses we identified important biological predictors for classifying the aquatic state either as flowing or disconnected pools. Flow cessation was critical for one of the streamflow indices studied and for community composition. Macroinvertebrate families found to be important for classifying the aquatic state were Hydrophilidae, Simuliidae, Hydropsychidae, Planorbiidae, Heptageniidae and Gerridae. For biological traits, trait categories associated to feeding habits, food, locomotion and substrate relation were the most important and provided more accurate predictions compared to taxonomy. A combination of selected metrics and associated thresholds based on the most important biological predictors (i.e. Bio-AS Tool) were proposed in order to assess the aquatic state in reference temporary streams, especially in the absence of hydrological data. Although further development is needed, the tool can be of particular interest for monitoring, restoration, and conservation purposes, representing an important step towards an adequate management of temporary rivers not only in the Mediterranean Basin but also in other regions vulnerable to the effects of climate change.

  2. Simple Words and Fuzzy Zones: Early Directions for Temporary River Research in South Africa

    1997-07-01

    / Although a large proportion of South Africa's rivers are nonperennial, ecological research into these systems has only recently been initiated. Consequently, we have little verified information about the ecological functioning of these rivers or knowledge of how best to manage them. High water demands in a semiarid region results in the flow of most perennial rivers being altered from permanent to temporary in sections, through impoundment, land-use changes, abstraction, etc. Conversely, sections of many temporary rivers are altered to perennial as a result of interbasin transfers or may be exploited for surface water. Effective and appropriate management of these modifications must be based on sound scientific information, which requires intensified, directed research. We anticipate that temporary river research in South Africa will, of necessity, be driven primarily by short-term collaborative efforts and secondarily by long-term ecological studies. At the outset, a simple conceptual framework is required to encourage an appreciation of current views of the spatial and temporal dynamics of nonperennial rivers and of the variability and unpredictability that characterize these systems. We adopt the view that perennial and episodic/ephemeral rivers represent either end of a continuum, separated by a suite of intermediate flow regimes. A conceptual diagram of this continuum is presented. In the absence of a functional classification for temporary rivers, a descriptive terminology has been systematically devised in an attempt to standardize definition of the different types of river regimes encountered in the country. Present terminology lacks structure and commonly accepted working definitions.

    This study analysed interactions between job insecurity and temporary employment and health. We tested the violation hypothesis (whether permanent employment increases the health risk associated with job insecurity) and the intensification hypothesis (whether temporary employment increases the health risk associated with job insecurity) in a longitudinal setting. Previous research on this topic is scarce and based on cross-sectional data. A population cohort (n=1071) was surveyed at age 30 and age 42. Exposure to temporary employment during this 12-year period was elicited with a job-time matrix and measured as the score of 6-month periods. Exposure to job insecurity was measured according to the perceived threat of unemployment. Health at follow-up was assessed as optimal versus suboptimal self-rated health, sleep quality and mental health. In addition to sociodemographics and baseline health, the analyses were adjusted for exposure to unemployment, non-employment and self-employment during the 12-year period. 26% of participants had been exposed to temporary employment. The effect of job insecurity on health was the same in the exposed and unexposed groups, that is the violation hypothesis was not supported. Non-significant interactions between the exposures and all health outcomes also indicated null findings regarding the intensification hypothesis. These findings suggest that perceived job insecurity can lead to adverse health effects in both permanent and temporary employees. Policies should aim to improve work-related well-being by reducing job insecurity. Efforts towards 'flexicurity' are important, but it is equally important to remember that a significant proportion of employees with a permanent contract experience job insecurity.

    A temporary dental implant is a medical device which is temporarily used to support a prosthesis such as an artificial tooth used for restoring patient's masticatory function during implant treatment. It is implanted in the oral cavity to substitute for the role of tooth. Due to the aging and westernization of current Korean society, the number of tooth extraction and implantation procedures is increasing, leading to an increase in the use and development of temporary dental implants. Because an implant performs a masticatory function in place of a tooth, a dynamic load is repeatedly put on the implant. Thus, the fatigue of implants is reported to be the most common causes of the fracture thereof. According to the investigation and analysis of the current domestic and international standards, the standard for fatigue of implant fixtures is not separately specified. Although a test method for measuring the fatigue is suggested in an ISO standard, it is a standard for permanent dental implants. Most of the test standards for Korean manufacturers and importers apply 250 N or more based on the guidance for the safety and performance evaluation of dental implants. Therefore, this study is intended to figure out the fatigue standard which can be applied to temporary dental implants when measuring the fatigue according to the test method suggested in the permanent dental implant standard. The results determined that suitable fatigue standards of temporary dental implants should be provided by each manufacturer rather than applying 250 N. This study will be useful for the establishment of the fatigue standards and fatigue test methods of the manufacturers and importers of temporary dental implants.

    In recent years, there has been a mass migration of Eritreans (many seeking political asylum) into Israel after precarious irregular movement across international borders. This study qualitatively explores the structural barriers to family planning (i.e. contraceptive services) for Eritrean women in Israel that are rooted in their temporary legal status and the patchwork of family planning services. From December 2012 to September 2013, we interviewed 25 key informants (NGO workers, researchers, Eritrean community activists, International NGO representatives and Ministry of Health officials) and 12 Eritrean asylum seekers. We also conducted 8 focus groups with Eritrean asylum seekers. Data were analyzed using both inductive and deductive coding. We identified 7 main barriers to accessing family planning services: (1) distance to health facilities; (2) limited healthcare resources; (3) fragmentation of the healthcare system; (4) cost of contraceptive services; (5) low standard of care in private clinics; (6) discrimination; and (7) language barriers. The political, economic and social marginalization of Eritrean asylum-seeking women in Israel creates structural barriers to family planning services. Their marginalization complicates providers' efforts (NGO and governmental) to provide them with comprehensive healthcare, and hinders their ability to control their sexual and reproductive health. Failure to act on this evidence may perpetuate the pattern of unwanted pregnancies and social and economic disparities in this population.

    Full Text Available The cross-cultural temporary resident population is one of the fastest growing cultural groups in the United States. However, their housing experiences in the new environment have not been extensively studied. Thus, the current study sought to examine meanings of dwelling attributes for cross-cultural temporary residents in the host country. In order to obtain insights into not only functional meanings but also underlying values, a conceptual framework was developed based primarily on Gutman’s (1982 means-end theory and Rapoport’s (1988 three levels of meaning. A case study was conducted using indepth laddering interviews with ten Korean temporary residents in the Lansing, Michigan, area. Seven dwelling attributes emerged from interviews: two satisfactory attributes (i.e., surrounding natural environment and architecture and five unsatisfactory attributes (i.e., carpeted floor, interior lighting, acoustics, bathroom, and entryway. Data were analyzed utilizing the measurement of means-end chain (Gutman, 1982, identifying the lower-level, everyday meanings as well as middle-level, latent meanings of dwelling attributes. A hierarchical value map was used to illustrate the interrelationships among the attributes, consequences, and values. Results revealed that dwelling attributes in participants’ current housing did not effectively satisfy their fundamental needs. In particular, carpeted floor was linked to the greatest number of negative meanings. Moreover, the cultural aspects of Korean housing affected the meanings of dwelling attributes in participants’ current homes. Findings suggest design professionals, facility managers, and policymakers must understand how people from other cultures attach different meanings to the dwelling attributes in their homes and provide more culturally responsive residential environments.

    The invertebrate blood-brain barrier (BBB) field is growing at a rapid pace and, in recent years, studies have shown a physiologic and molecular complexity that has begun to rival its vertebrate counterpart. Novel mechanisms of paracellular barrier maintenance through G-protein coupled receptor signaling were the first demonstrations of the complex adaptive mechanisms of barrier physiology. Building upon this work, the integrity of the invertebrate BBB has recently been shown to require coordinated function of all layers of the compound barrier structure, analogous to signaling between the layers of the vertebrate neurovascular unit. These findings strengthen the notion that many BBB mechanisms are conserved between vertebrates and invertebrates, and suggest that novel findings in invertebrate model organisms will have a significant impact on the understanding of vertebrate BBB functions. In this vein, important roles in coordinating localized and systemic signaling to dictate organism development and growth are beginning to show how the BBB can govern whole animal physiologies. This includes novel functions of BBB gap junctions in orchestrating synchronized neuroblast proliferation, and of BBB secreted antagonists of insulin receptor signaling. These advancements and others are pushing the field forward in exciting new directions. In this review, we provide a synopsis of invertebrate BBB anatomy and physiology, with a focus on insights from the past 5 years, and highlight important areas for future study.

    Full Text Available The art of communication – listening and speaking – is a major life skill, with a thorough influence on every human life. Remaining silent while the interlocutor speaks is not all that there is to the act of listening to messages. True listening is based on an intention to get involved in understanding of the other person, enjoying his or her presence, learning something from the conversation, giving assistance, or comforting the interlocutor. In the article the author describes obstacles (barriers, which render true listening impossible. These barriers have been identified by a group of young adults.

  14. Enhanced tunneling through nonstationary barriers

    Palomares-Baez, J. P.; Rodriguez-Lopez, J. L.; Ivlev, B.

    2007-01-01

    Quantum tunneling through a nonstationary barrier is studied analytically and by a direct numerical solution of Schroedinger equation. Both methods are in agreement and say that the main features of the phenomenon can be described in terms of classical trajectories which are solutions of Newton's equation in complex time. The probability of tunneling is governed by analytical properties of a time-dependent perturbation and the classical trajectory in the plane of complex time. Some preliminary numerical calculations of Euclidean resonance (an easy penetration through a classical nonstationary barrier due to an underbarrier interference) are presented

    Aquatic life in temporary streams is strongly conditioned by the temporal variability of the hydrological conditions that control the occurrence and connectivity of diverse mesohabitats. In this context, the software TREHS (Temporary Rivers' Ecological and Hydrological Status) has been developed, in the framework of the LIFE Trivers project, to help managers for adequately implement the Water Framework Directive in this type of water bodies. TREHS, using the methodology described in Gallart et al (2012), defines six temporal 'aquatic states', based on the hydrological conditions representing different mesohabitats, for a given reach at a particular moment. Nevertheless, hydrological data for assessing the regime of temporary streams are often non-existent or scarce. The scarcity of flow data makes frequently impossible the characterization of temporary streams hydrological regimes and, as a consequence, the selection of the correct periods and methods to determine their ecological status. Because of its qualitative nature, the TREHS approach allows the use of alternative methodologies to assess the regime of temporary streams in the lack of observed flow data. However, to adapt the TREHS to this qualitative data both the temporal scheme (from monthly to seasonal) as well as the number of aquatic states (from 6 to 3) have been modified. Two alternatives complementary methodologies were tested within the TREHS framework to assess the regime of temporary streams: interviews and aerial photographs. All the gauging stations (13) belonging to the Catalan Internal Catchments (NE, Spain) with recurrent zero flows periods were selected to validate both methodologies. On one hand, non-structured interviews were carried out to inhabitants of villages and small towns near the gauging stations. Flow permanence metrics for input into TREHS were drawn from the notes taken during the interviews. On the other hand, the historical series of available aerial photographs (typically 10

    2012-01-01

    Full Text Available Context: Walking bleach technique uses 30% hydrogen peroxide and sodium perborate, and this paste mixture causes loosening of the coronal temporary restorative materials and thus decreasing its clinical effectiveness and causing irritation to the patients oral tissues. In the present study, sealing ability of hygroscopic coronal temporary restorative materials were compared with the other commonly used temporary restorative materials. Aim: To evaluate the effects of walking bleach material on the marginal sealing ability and coronal microleakage of the hydrophilic temporary restorative materials with that of the other commonly used temporary restorative materials in endodontic practice. Materials and Methods: Seventy-five extracted human maxillary central incisor teeth were prepared chemo-mechanically and obturated with gutta-percha in lateral condensation technique. Surface of each tooth was double coated with cyanoacrylate glue. All the teeth were randomly divided in to five groups. Out of 15 teeth in each group, 10 teeth served as experimental specimens, in which bleaching agent was placed in the pulp chamber and 5 teeth served as control, in which no bleaching agent was placed. The access cavities were restored with temporary restorative materials being tested per each group respectively. The specimens were then immersed in 1% India ink dye and subjected to thermo cycling for 7 days. All the teeth were longitudinally sectioned and observed with stereomicroscope and were graded according to the depth of linear dye penetration. Statistical Analysis Used: Mann-Whitney U test and Kruskal-Wallis test. Results: Hydrophilic temporary restorative materials Cavit G and Coltosol F have shown minimal coronal dye leakage with better sealing ability when exposed to walking bleach paste mixture in the dye penetration tests compared to other commonly used temporary restorative materials. Conclusion: Marginal sealing ability of Cavit G and Coltosol F were

    A performance assessment model for multiple barrier packages containing unreprocessed spent fuel has been modified and applied to several package designs. The objective of the study was to develop information to be used in programmatic decision making concerning engineered barrier package design and development. The assessment model, BARIER, was developed in previous tasks of the System Study on Engineered Barriers (SSEB). The new version discussed in this report contains a refined and expanded corrosion rate data base which includes pitting, crack growth, and graphitization as well as bulk corrosion. Corrosion rates for oxic and anoxic conditions at each of the two temperature ranges are supplied. Other improvements include a rigorous treatment of radionuclide release after package failure which includes resistance of damaged barriers and backfill, refined temperature calculations that account for convection and radiation, a subroutine to calculate nuclear gamma radiation field at each barrier surface, refined stress calculations with reduced conservatism and various coding improvements to improve running time and core usage. This report also contains discussion of alternative scenarios to the assumed flooded repository as well as the impact of water exclusion backfills. The model was used to assess post repository closure performance for several designs which were all variation of basic designs from the Spent Unreprocessed Fuel (SURF) program. Many designs were found to delay the onset of leaching by at least a few hundreds of years in all geologic media. Long delay times for radionuclide release were found for packages with a few inches of sorption backfill. Release of uranium, plutonium, and americium was assessed

    To explore oncologists' psychosocial attitudes and beliefs and their perceptions regarding barriers against psychosocial communication. A questionnaire was distributed to oncologists in Sweden (n = 537). Questions covered demography, the Physician Psychosocial Beliefs Scale (PPBS), and barriers against psychosocial communication. Stepwise multiple regression was used to determine what factors contribute the most to the PPBS score and the total number of barriers and barriers affecting clinical practice, respectively. Spearman rank-order correlation was used to determine correlation between PPBS score and number of barriers. Questionnaire response rate was 64%. Mean PPBS value was 85.5 (range, 49 to 123; SD, 13.0). Most oncologists (93%) perceived one or more barriers in communicating psychosocial aspects with patients. On average, five different communication barriers were perceived, of which most were perceived to affect clinical practice. These barriers included insufficient consultation time, lack of resources for taking care of problems discovered, and lack of methods to evaluate patients' psychosocial health in clinical practice. There was a positive correlation (rs = 0.490; P barriers (ie, less psychosocially oriented oncologists perceived more barriers). Oncologists with supplementary education with a psychosocial focus perceived fewer barriers/barriers affecting clinical practice (P barriers affecting psychosocial communication in clinical practice. Interventions aiming to improve psychosocial communication must therefore be multifaceted and individualized to clinics and individual oncologists. It is important to minimize barriers to facilitate optimal care and treatment of patients with cancer.
