    This report documents tests conducted by Sandia National Laboratories (SNL) on behalf of the U.S. Department of State to evaluate a temporary anti-personnel (TAP) barrier system developed by Mitigation Technologies. For this, the SNL Denial and Structural Assessment department developed a test protocol for the evaluation of the TAP barrier system on the basis of deployment efficiency and barrier effectiveness against a riotous/mob attack threat. The test protocol was then executed by SNL personnel and the results of the testing are documented.

  2. Hyperthermic Laser Ablation of Recurrent Glioblastoma Leads to Temporary Disruption of the Peritumoral Blood Brain Barrier.

    Full Text Available Poor central nervous system penetration of cytotoxic drugs due to the blood brain barrier (BBB is a major limiting factor in the treatment of brain tumors. Most recurrent glioblastomas (GBM occur within the peritumoral region. In this study, we describe a hyperthemic method to induce temporary disruption of the peritumoral BBB that can potentially be used to enhance drug delivery.Twenty patients with probable recurrent GBM were enrolled in this study. Fourteen patients were evaluable. MRI-guided laser interstitial thermal therapy was applied to achieve both tumor cytoreduction and disruption of the peritumoral BBB. To determine the degree and timing of peritumoral BBB disruption, dynamic contrast-enhancement brain MRI was used to calculate the vascular transfer constant (Ktrans in the peritumoral region as direct measures of BBB permeability before and after laser ablation. Serum levels of brain-specific enolase, also known as neuron-specific enolase, were also measured and used as an independent quantification of BBB disruption.In all 14 evaluable patients, Ktrans levels peaked immediately post laser ablation, followed by a gradual decline over the following 4 weeks. Serum BSE concentrations increased shortly after laser ablation and peaked in 1-3 weeks before decreasing to baseline by 6 weeks.The data from our pilot research support that disruption of the peritumoral BBB was induced by hyperthemia with the peak of high permeability occurring within 1-2 weeks after laser ablation and resolving by 4-6 weeks. This provides a therapeutic window of opportunity during which delivery of BBB-impermeant therapeutic agents may be enhanced.ClinicalTrials.gov NCT01851733.

    The influence of reperfusion after profound incomplete forebrain ischemia on blood-brain barrier (BBB) permeability to a small protein tracer was studied in male Sprague-Dawley rats. The mean cortical blood to brain transfer constant (Ki) for /sup 14/C-amino isobutyric acid (AIB) was significantly greater at 3 and 6 h of reperfusion, 2.5 times the mean values of controls (p less than 0.05) (2.5 microliter g-1 min-1 and 1.0 microliters g-1 min-1 respectively), but had returned to control values after reperfusion for 24 h. Analysis of distribution of Ki values showed that following 15 min and 30 min of profound ischemia, there was a significant increase in transfer of AIB across the blood-brain barrier (BBB) after recirculation for up to 6 h, though there was no evidence of protein extravasation as assessed by Evans Blue (EB) dye. After 24 h of reperfusion, the BBB to AIB was restored, and Ki values had returned to control values. It is concluded that following transient global ischemia, the BBB may recover rapidly.

    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....

  8. Temporary internal pacing.

    2014-12-01

    Technology and insertion techniques for cardiac temporary internal pacing have experienced a remarkable development over the last few years. Despite this fact, the procedure continues to have potentially fatal associated complications. Temporary internal pacing is indicated for the treatment of bradyarrhythmias or tachyarrhythmias refractory to conventional treatment, or arrhythmias causing cardiovascular or clinical instability of the patient. On the other hand, the indications of temporary cardiac pacing are far less well defined than those of permanent pacing. Since the decision of implementing temporary pacing is complex and delicate, it should always be carefully considered, and over-indication should be avoided. We must base these decisions on robust knowledge of the arrhythmias that may benefit from temporary internal pacing, and should also acquire the habit of considering external temporary pacing among other less aggressive treatments, and to make the best use of new technologies such as echocardiography that add accuracy to the procedure.

    A temporary face support is proposed. It includes a beam supported by hydraulic jacks on the housing of the cutter-loader with a working tool and rotary pressure regulator. It differs in that to decrease the volume of unsecured roofing in the face space between the leading edge of the beam and the cutting tool of the cutter-loader, the beam is hinged onto the housing of the rotary pressure regulator by a fastened connecting rod, and the hydraulic jacks are provided with additional powered elements with a mechanism that regulates the length of the cut-off plate of the hydraulic pump when the seam pressure changes.

    Because of their temporary nature, work and employment in project based organizations are different from what we used to see in traditional organizational forms. Temporary employment, entailing less stability within the organization changes how employment and work are organized. Temporary systems...... are organized by transcending organization that go beyond the individual firm and replaces what used to be organized inside the firm.

    Temporary foreign workers contribute to economic prosperity in Canada, but they experience forms of structural inequities and have minimal rights, which can contribute to their ill health. The objective of this scoping review is to examine the extent, range and nature of the Canadian literature on the health of temporary foreign workers and their families in Canada. The review was guided by Arksey and O'Malley's five stages for conducting a scoping review. We performed a comprehensive search of seven databases, which revealed 994 studies. In total, 10 published research papers, which focused exclusively on the health of temporary foreign workers in Canada, were included in the study; these 10 papers represented the findings from 9 studies. The majority of the studies involved seasonal agricultural workers in the province of Ontario (n = 8). Major health issues of temporary foreign workers included mental health, occupational health, poor housing and sanitation, and barriers to accessing health care, including fear of deportation and language barriers. These health issues are highly shaped by temporary foreign workers' precarious immigration status in Canada. Findings from this study demonstrate the need to reduce barriers to health care and to conduct more research on other groups of temporary foreign workers, outside the agricultural sector.

    Marickar, Y M Fazil; Salim, Abiya

    2009-12-01

    We have been using a risk index calculation for urolithiasis, which included most of the identifiable factors promoting calculogenesis. However, it was observed that the frequency of a patient getting stone problem was not uniform in spite of similarity of the risk index in the permanent setting. Also, many of the risk indices could be changed by dietary or lifestyle modifications. The objective of this paper was to calculate the temporary risk index of a patient at the time of each visit and correlate with stone activity during such periods, so that appropriate advice could be given on drugs, diet and lifestyle changes. The temporary risk index score was based on four symptoms, namely pain (0, nil; 1, vague pain; 2, mild; 3, moderate; 4, severe; 5, excruciating), haematuria (0, nil; 1, turbid; 2, cloudy; 3, reddish; 4, occasional frank blood; 5, continuous frank blood), burning sensation (0, nil; 1, minimal; 2, moderate; 3, terminal severe; 4, occasional excruciating; 5, continuous excruciating), and dysuria (0, nil; 1, minimal; 2, moderate; 3, terminal severe; 4, occasional excruciating, 5, continuous excruciating), ultrasonography for back pressure (0, nil; 1, mild; 2, moderate; 3, severe kidney and ureter; 4, unilateral total; 5, bilateral total anuria) and eight urine deposit findings (0, nil; 1, +; 2, 2+; 3, 3+; 4, 4+; 5, plenty), red blood cells, pus cells, whewellite crystals, weddellite crystals, phosphate crystals, uric acid/ammonium urate crystals, crystal clumping and crystal aggregation making a total of 13 parameters. Each parameter was given values ranging from 0 to 5. The total score was calculated and chemotherapeutic regimes were decided base on the score, which varied from 0 to 65. Hundred randomly selected patients who had been visiting the stone clinic for a minimum of five occasions were included in the study. The total scores of temporary risk were correlated with the permanent clinical risk score mentioned earlier. The temporary risk of the

    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.

  2. Large capacity temporary visual memory

    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.

    A completely new Administrative Procedure for temporary shielding was developed for use at Commonwealth Edison`s six nuclear stations. This procedure promotes the use of shielding, and addresses industry requirements for the use and control of temporary shielding. The importance of an effective procedure has increased since more temporary shielding is being used as ALARA goals become more ambitious. To help implement the administrative procedure, a personal computer software program was written to incorporate the procedural requirements. This software incorporates the useability of a Windows graphical user interface with extensive help and database features. This combination of a comprehensive administrative procedure and user friendly software promotes the effective use and management of temporary shielding while ensuring that industry requirements are met.

    2006-04-01

    Male boreal toads (Bufo boreas) are thought to return to the breeding site every year but, if absent in a particular year, will be more likely to return the following year. Using Pollock's robust design we estimated temporary emigration (the probability a male toad is absent from a breeding site in a given year) at three locations in Colorado, USA: two in Rocky Mountain National Park and one in Chaffee County. We present data that suggest that not all male toads return to the breeding site every year. Our analyses indicate that temporary emigration varies by site and time (for example, from 1992 to 1998, the probability of temporary emigration ranged from 10% to 29% and from 3% to 95% at Lost Lake and Kettle Tarn, respectively). Although the results provide weak evidence that males are more likely to return after a year's hiatus, a general pattern of state-dependent temporary emigration was not supported. We also hypothesized relationships between temporary emigration and a number of weather variables. While some competitive models included weather covariates, imprecise and variable estimates of the effects of these covariates precluded fully defining their impact on temporary emigration.

  13. Need for adaptation: transformation of temporary houses.

    2017-10-01

    Building permanent accommodation after a disaster takes time for reasons including the removal of debris, the lack of available land, and the procurement of resources. In the period in-between, affected communities find shelter in different ways. Temporary houses or transitional shelters are used when families cannot return to their pre-disaster homes and no other alternative can be provided. In practice, families stay in a standard interim solution for months or even years while trying to return to their routines. Consequently, they adapt their houses to meet their midterm needs. This study analysed temporary houses in Chile and Peru to illustrate how families modify them with or without external support. The paper underlines that guidance must be given on how to alter them safely and on how to incorporate the temporary solution into the permanent structure, because families adapt their houses whether or not they are so designed. © 2017 The Author(s).

  14. Closing a temporary ileostomy within two weeks.

    Hindenburg, Tommy; Rosenberg, Jacob

    2010-06-01

    Temporary ileostomy is frequently constructed to relieve a rectal anastomosis and avoid peritonitis if the anastomosis is leaking. Ostomy is a burden for both the patient and society and early closure is therefore desirable to counteract increased morbidity. Several prospective studies and a single randomized controlled trial have shown that closure in less than two weeks was associated with lower or equal morbidity compared with later closure. Thus, current data support early closure of temporary ileostomy performed to cover rectal anastomosis in routine clinical practice.

It is wiser to learn to work with current structure realizing that supply and demand plays an important role in the survival and success of agencies. Although there are problems associated with temporary nursing staffing, they are surmountable. Orientation programs, performance monitoring, ensuring accountability of both nurse and agency are but a few that can enhance utilization and quality of service.

    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.

    Many highly mobile species are known to use persistent pathways or corridors to move between habitat patches in which conditions are favorable for particular activities, such as breeding or foraging. In the marine realm, environmental variability can lead to the development of temporary periods of anomalous oceanographic conditions that can connect individuals to areas of habitat outside a population's usual range, or alternatively, restrict individuals from areas usually within their range, thus acting as ecological bridges or ecological barriers. These temporary features can result in novel or irregular trophic interactions and changes in population spatial dynamics, and, therefore, may have significant implications for management of marine ecosystems. Here, we provide evidence of ecological bridges and barriers in different ocean regions, drawing upon five case studies in which particular oceanographic conditions have facilitated or restricted the movements of individuals from highly migratory species. We discuss the potential population-level significance of ecological bridges and barriers, with respect to the life history characteristics of different species, and inter- and intra-population variability in habitat use. Finally, we summarize the persistence of bridge dynamics with time, our ability to monitor bridges and barriers in a changing climate, and implications for forecasting future climate-mediated ecosystem change.

    The aim of this study was to evaluate the fracture resistance of various provisional crown materials using an in vitro model test system. In the present study polycarbonate crowns, prefabricated by the manufacturer (3M Polycarbonate Crown), and the temporary crowns, fabricated in the dental laboratory environment, were fabricated using bis-acryl composite (Protemp II), autopolymerizing PMMA resin (BISICO Temp S), and heat-polymerized PMMA resin (Major C&B-V Dentine). All temporary crowns were stored in distilled water for 24 hours at room temperature prior to testing. The crowns were seated on metal dies, fabricated from Cr-Co alloy (AZ Dental, Konstanz, Germany), and then tested using the indenter of a Hounsfield testing machine (Hounsfield Tensometer, Hounsfield Test Equipment, Raydon, England). The tip of the indenter was located at a position one-third of the way down the inciso-palatine surface at 135 masculine. The data were statistically analyzed for differences using one-way analysis of variance (ANOVA) and the Tukey HSD test (P polycarbonate crowns were significantly different from the BISICO Temp S, Protemp II, and Major C&B-V Dentine (P polycarbonate crowns may be preferable to the other types of temporary crowns used in this study.

  16. Temporary refugia for coral reefs in a warming world

    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.

  17. Empirical correlation methods for temporary anions.

    Science.gov (United States)

    Sommerfeld, Thomas; Weber, Rebecca J

    2011-06-23

    A temporary anion is a short-lived radical anion that decays through electron autodetachment into a neutral molecule and a free electron. The energies of these metastable species are often predicted using empirical correlation methods because ab initio predictions are computationally very expensive. Empirical correlation methods can be justified in the framework of Weisskopf-Fano-Feshbach theory but tend to work well only within closely related families of molecules or within a restricted energy range. The reason for this behavior can be understood using an alternative theoretical justification in the framework of the Hazi-Taylor stabilization method, which suggests that the empirical parameters do not so much correct for the coupling of the computed state to the continuum but for electron correlation effects and that therefore empirical correlation methods can be improved by using more accurate electronic structure methods to compute the energy of the confined electron. This idea is tested by choosing a heterogeneous reference set of temporary states and comparing empirical correlation schemes based on Hartree-Fock orbital energies, Kohn-Sham orbital energies, and attachment energies computed with the equation-of-motion coupled-cluster method. The results show that using more reliable energies for the confined electron indeed enhances the predictive power of empirical correlation schemes and that useful correlations can be established beyond closely related families of molecules. Certain types of σ* states are still problematic, and the reasons for this behavior are analyzed. On the other hand, preliminary results suggest that the new scheme can even be useful for predicting energies of bound anions at a fraction of the computational cost of reliable ab initio calculations. It is then used to make predictions for bound and temporary states of the furantrione and croconic acid radical anions.

    1976-04-01

    Strict criteria for the diagnosis of temporary gluten intolerance are formulated in the light of the case of an 8-week-old infant with severe diarrhoea and failure to thrive, who recovered on an elimination diet that was gluten-free. 8 weeks later an oral challenge with 2.5 g twice daily of powdered gluten for one day produced diarrhoea, weight loss, and impaired xylose absorption. Gluten was successfully reintroduced into the diet 9 months later without incident. Jejunal histology remains normal after 26 months of a daily diet that contains 5 to 10 g gluten.

    The color vision has been described as one to be very sensitive to the intake of several chemicals. The present research reviews the published literature that is concerned with color vision impairment due to alcohol. Most of this research considers people under long-term effects of alcohol. However, there is little information about temporary effects of alcohol on color vision. A group of ten volunteers aged 18-40 was studied. During the study levels of alcohol in the body were tested with a standard breathalyzer while color vision were studied using Farnsworth Munsell 100 Hue Color Vision Tests. Keywords: Col

    Singh, Kamlesh; Kumar, Deepak; Jaiswal, Raj Kumar; Bansal, Amol

    2010-01-01

    Orthodontists are accustomed to using teeth and auxiliary appliances, both intraoral and extraoral, to control anchorage. These methods are limited in that it is often difficult to achieve results commensurate with our idealistic goals. Recently, a number of case reports have appeared in the orthodontic literature documenting the possibility of overcoming anchorage limitations via the use of temporary anchorage devices—biocompatible devices fixed to bone for the purpose of moving teeth, with the devices being subsequently removed after treatment. Although skeletal anchorage is here to stay in orthodontics, there are still many unanswered questions. This article describes the development of skeletal anchorage and provides an overview of the use of implants for orthodontic anchorage. PMID:22442547

    A series of tests was carried out to evaluate the performance of a crash barrier designed to protect the occupants of an automobile from serious injury. The JPL barrier design is a configuration of empty aluminum beverage cans contained in a tear-resistant bag which, in turn, is encased in a collapsible container made of plywood and steel. Tests were conducted with a driven vehicle impacting the barrier. The basic requirements of NCHRP Report 153 were followed except that speeds of 30 mph rather than 60 mph were used. Accelerometer readings on the driver's helmet showed that the driver was never subjected to dangerous decelerations, and never experienced more than temporary discomfort. Also, all of the requirements of the cited report were met. An extrapolation of data indicated that the JPL barrier installed in front of a tree or telephone pole along a roadside would also have met the requirements at a speed of 40 mph.

  14. Permanent and temporary pacemaker implantation after orthotopic heart transplantation

    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.

  15. Return to Work After Temporary Disability Pension in Finland.

    2015-09-01

    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.

    Pepłowski, Andrzej; Janczak, Daniel; Krzemińska, Patrycja; Jakubowska, Małgorzata

    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.

    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.

    Part of the local economic impact of a major sporting event comes from the associated temporary tourism expenditures. Typically demand-driven Input-Output (IO) methods are used to quantify the impacts of such expenditures. However, IO modelling has specific weaknesses when measuring temporary tourism impacts; particular problems lie in its treatment of factor supplies and its lack of dynamics. Recent work argues that Computable General Equilibrium (CGE) analysis is more appropriate and this h...

    2008-07-01

    Little is known about the incidence of temporary kidney dysfunction following major vascular surgeries. We aimed to assess the frequency of temporary decreased kidney function following aortic surgeries. In a retrospective study, we assessed 108 hospital records of the patients who had undergone elective open abdominal surgery of aortic aneurysm. Preoperative and postoperative (days 1, 2, and 3) data on estimated glomerular filtration rate (GFR) were collected and evaluated in relation to the patients' clinical characteristics and outcomes. A decline greater than 10% in GFR on day 1 or 2, and then, an increase of GFR to a level of maximum 10% below the baseline value on the third postoperative day was considered as temporary worsening of kidney function. Postoperative alterations of GFR not greater than 10% in relation to the baseline were considered as improved or unchanged kidney function. Two patients with persistent decrease in GFR were excluded. Temporary worsening of kidney function was seen in 25 patients (23.6%). Short-term mortality rate was 44.0% in this group of patients, while it was 17.3% in those without decreased GFR (P = .006). According to the regression analysis, the only predictor of mortality was temporary worsening of kidney function, with a hazard ratio of 4.03 (95% confidence interval, 1.44 to 11.31; P = .008). Nearly 1 out of 4 aortic surgeries results in kidney dysfunction. Albeit temporary in most cases, it seems to be associated with a higher short-term mortality rate.

  8. Temporary jobs and the severity of workplace accidents.

    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.

    Temporary henna tattoos have become increasingly popular as a safe alternative to permanent tattoos among American and European children and teenagers during the summer holidays. Currently, temporary henna tattoos contain not only henna, but also other additives such as para-phemylenediamine (PPD), which is considered to be the chemical agent that most frequently causes skin reactions associated with the use of commercial black henna. In this report, we describe an 11-year-old boy who applied a temporary black henna tattoo on his right arm during the summer holidays in Greece and developed a severe contact dermatitis at the tattoo site with residual hypopigmentation. He had no previous history of contact dermatitis, however he did suffer from seasonal allergic rhinitis and atopic dermatitis. Patch testing revealed a strong reaction to PPD, a substance commonly contained in temporary henna tattoo preparations. Henna tattoos are an increasing problem worldwide since they carry an increased risk of severe skin reactions; therefore we suggest that the use of temporary henna tattoos in children be discouraged.

  11. Temporary Cementitious Sealers in Enhanced Geothermal Systems

    Energy Technology Data Exchange (ETDEWEB)

    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

  12. 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.

  13. Deploying temporary networks for upscaling of sparse network stations

    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.

    The paper involves exposure to noise of the State Police officers connected with the use of firearms. The noise generated by these weapons is of short duration and high intensity. The research was carried out during the sessions of firearm training of State Police officers to assess exposure to noise. The values of the various investigations, both audiometric and phonometric, carried out made it possible to demonstrate a significant exposure and a temporary increase in the threshold, above the frequency of 6000 Hz. Even taking account of the abatement from use of headphones, an exposure was demonstrated that was above the statutory limits, as was confirmed by the temporary hearing threshold shift.

    A temporary demand pacemaker with electrocardiosignal display is introduced in this paper. Double way low-noise electrocardiosignal preamplifier, amplitude limiter, high and low pass filter, 50 Hz notch filter, TTL level generator and stimulating pulse formation circuit are components of the hardware electrocircuit. The demand pacing and the electrocardiosignal display are separately controlled by the software in which the double microcontrollers communications technique is used. In this study, liquid crystal display is firstly used in body surface electrocardiosignal display or intracardial electrophysiologic signal display when the temporary demand pacemaker is installed and put into use. The machine has proven clinically useful and can be of wide appliation.

    2013-08-01

    There is an ongoing debate about the reasons for the growth of temporary employment of registered nurses (RNs). Some argue that efficiency incentives to increase flexibility and reduce labor costs are the principal cause, while others point to shortages of RNs as the stronger determinant. Using hospital-level data from California's Office of Statewide Health Planning and Development, we find a significant trend of increasing demand for agency nurses during the years of RN shortage. Demand rose with inpatient days, patient demand fluctuation, and the level of fringe benefits. Competition between hospitals and unionization, however, did not affect hospitals' demand for temporary RNs. © The Author(s) 2014.

    Full Text Available Temporary henna tattoos have become very popular among children and teenagers in recent years. However, the use of additives to shorten the application time and darken the color of commercial henna, such as para-phenylenediamine, has led to an increased risk of complications due to those tattoos. The most commonly seen complications are allergic contact dermatitis, hypertrophic scarring, keloid formation, hyperpigmentation, and hypopigmentation. Herein; a 13-year-old girl who developed localized hypertrichosis after a temporary henna tattoo application was presented.

  2. Reconsolidated Salt as a Geotechnical Barrier

    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.

  6. 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.

    To compare PermeaDerm to first temporary biosynthetic skin substitute (Biobrane, cleared by the Food and Drug Administration in 1979). Different temporary skin substitutes (Biobrane, PermeaDerm, and PermeaDerm derivatives) were tested for physical differences, impact on healing wounds, inflammatory response, and ability to allow adequate growth of dermal fibroblasts and mesenchymal stem cells without accumulation of excessive scar-forming myofibroblasts. Proliferation of fibroblasts and stem cells on various skin substitutes was measured, and myofibroblast marker accumulation was evaluated by the expression of α-smooth muscle actin and fibronectin. Fibroblast migration was measured by tracking viable cells with MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide] dye. In vivo testing shows PermeaDerm works well as a temporary skin substitute, performing better than Biobrane with respect to inflammation and fluid accumulation. Tissue culture techniques revealed that cells on PermeaDerm grow in a more uniform fashion and migrated to a greater extent than cells on Biobrane. Furthermore, cells grown in the presence of PermeaDerm expressed lower levels of the myofibroblast markers α-smooth muscle actin and fibronectin than cells grown on Biobrane. PermeaDerm with variable porosity possesses all attributes and properties known to be important for a successful temporary skin substitute and enables the clinician to control porosity from essentially zero to what the wound requires. The ability of the clinician to minimize wound desiccation without fluid accumulation is related to the reduction of punctate scarring.

  7. HRE-Pond Cryogenic Barrier Technology Demonstration: Pre- and Post-Barrier Hydrologic Assessment

    Energy Technology Data Exchange (ETDEWEB)

    Moline, G.R.

    1999-06-01

    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 {sup 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{sub 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.

  15. Reducing bias in survival under non-random temporary emigration

    Science.gov (United States)

    Peñaloza, Claudia L.; Kendall, William L.; Langtimm, Catherine Ann

    2014-01-01

    Despite intensive monitoring, temporary emigration from the sampling area can induce bias severe enough for managers to discard life-history parameter estimates toward the terminus of the times series (terminal bias). Under random temporary emigration unbiased parameters can be estimated with CJS models. However, unmodeled Markovian temporary emigration causes bias in parameter estimates and an unobservable state is required to model this type of emigration. The robust design is most flexible when modeling temporary emigration, and partial solutions to mitigate bias have been identified, nonetheless there are conditions were terminal bias prevails. Long-lived species with high adult survival and highly variable non-random temporary emigration present terminal bias in survival estimates, despite being modeled with the robust design and suggested constraints. Because this bias is due to uncertainty about the fate of individuals that are undetected toward the end of the time series, solutions should involve using additional information on survival status or location of these individuals at that time. Using simulation, we evaluated the performance of models that jointly analyze robust design data and an additional source of ancillary data (predictive covariate on temporary emigration, telemetry, dead recovery, or auxiliary resightings) in reducing terminal bias in survival estimates. The auxiliary resighting and predictive covariate models reduced terminal bias the most. Additional telemetry data was effective at reducing terminal bias only when individuals were tracked for a minimum of two years. High adult survival of long-lived species made the joint model with recovery data ineffective at reducing terminal bias because of small-sample bias. The naïve constraint model (last and penultimate temporary emigration parameters made equal), was the least efficient, though still able to reduce terminal bias when compared to an unconstrained model. Joint analysis of several

  16. Temporary Losses of Highway Capacity and Impacts on Performance

    Energy Technology Data Exchange (ETDEWEB)

    Chin, S.M.

    2002-07-31

    Traffic congestion and its impacts significantly affect the nation's economic performance and the public's quality of life. In most urban areas, travel demand routinely exceeds highway capacity during peak periods. In addition, events such as crashes, vehicle breakdowns, work zones, adverse weather, and suboptimal signal timing cause temporary capacity losses, often worsening the conditions on already congested highway networks. The impacts of these temporary capacity losses include delay, reduced mobility, and reduced reliability of the highway system. They can also cause drivers to re-route or reschedule trips. Prior to this study, no nationwide estimates of temporary losses of highway capacity had been made by type of capacity-reducing event. Such information is vital to formulating sound public policies for the highway infrastructure and its operation. This study is an initial attempt to provide nationwide estimates of the capacity losses and delay caused by temporary capacity-reducing events. The objective of this study was to develop and implement methods for producing national-level estimates of the loss of capacity on the nation's highway facilities due to temporary phenomena as well as estimates of the impacts of such losses. The estimates produced by this study roughly indicate the magnitude of problems that are likely be addressed by the Congress during the next re-authorization of the Surface Transportation Programs. The scope of the study includes all urban and rural freeways and principal arterials in the nation's highway system for 1999. Specifically, this study attempts to quantify the extent of temporary capacity losses due to crashes, breakdowns, work zones, weather, and sub-optimal signal timing. These events can cause impacts such as capacity reduction, delays, trip rescheduling, rerouting, reduced mobility, and reduced reliability. This study focuses on the reduction of capacity and resulting delays caused by the temporary

  17. Industrial production and temporary development after the Emilian Earthquake.

    Matteo Scamporrino

    2014-02-01

    Full Text Available The earthquake that on the 20th of May hit Emilia has not been one of the most disastrous in modern Italian history, but it has highlighted the problem of preservation of industrial activities during a reconstruction process. In addition, precisely this system, characterized by great vitality and productivity but also by large seismic vulnerability, was the most affected. Through an analysis of the damages suffered by the industrial facilities, not so much as single buildings but precisely as a system, we want to highlight the challenges imposed by the earthquake: on the one hand, the urgent need to provide for delocalizations and temporary structures to avoid a stop in production in the short­term, and on the other, the re­design and anti­seismic re­planning of productive areas. A proposal was put forward to create temporary zones adjacent to the damaged areas, on which temporary structures should be installed. The latter would allow to limit relocations of medium­long range, which are negative for the territory, and at the same time it would allow the flexibility necessary to re­organize the supply chains. However, in Italy, the management of temporary solutions is seen as a practice too much linked to the emergency and too little to the reconstruction process. The first measures put into place by both the State and the Regions, however, do not seem to show a true understanding of the importance of management and regulations of temporary solutions in the medium­ long term.

  3. Complementary Barrier Infrared Detector

    Ting, David Z.; Bandara, Sumith V.; Hill, Cory J.; Gunapala, Sarath D.

    2009-01-01

    The complementary barrier infrared detector (CBIRD) is designed to eliminate the major dark current sources in the superlattice infrared detector. The concept can also be applied to bulk semiconductor- based infrared detectors. CBIRD uses two different types of specially designed barriers: an electron barrier that blocks electrons but not holes, and a hole barrier that blocks holes but not electrons. The CBIRD structure consists of an n-contact, a hole barrier, an absorber, an electron barrier, and a p-contact. The barriers are placed at the contact-absorber junctions where, in a conventional p-i-n detector structure, there normally are depletion regions that produce generation-recombination (GR) dark currents due to Shockley-Read- Hall (SRH) processes. The wider-bandgap complementary barriers suppress G-R dark current. The barriers also block diffusion dark currents generated in the diffusion wings in the neutral regions. In addition, the wider gap barriers serve to reduce tunneling dark currents. In the case of a superlattice-based absorber, the superlattice itself can be designed to suppress dark currents due to Auger processes. At the same time, the barriers actually help to enhance the collection of photo-generated carriers by deflecting the photo-carriers that are diffusing in the wrong direction (i.e., away from collectors) and redirecting them toward the collecting contacts. The contact layers are made from materials with narrower bandgaps than the barriers. This allows good ohmic contacts to be made, resulting in lower contact resistances. Previously, THALES Research and Technology (France) demonstrated detectors with bulk InAsSb (specifically InAs0.91Sb0.09) absorber lattice-matched to GaSb substrates. The absorber is surrounded by two wider bandgap layers designed to minimize impedance to photocurrent flow. The wide bandgap materials also serve as contacts. The cutoff wavelength of the InAsSb absorber is fixed. CBIRD may be considered as a modified

  4. Temporary Agency Workers—Precarious Workers? Perceived Job Security and Employability for Temporary Agency Workers and Client Organization Employees at a Swedish Manufacturing Plant

    Directory of Open Access Journals (Sweden)

    Kristina Håkansson

    2015-12-01

    Full Text Available The vulnerable situation of temporary agency workers is manifested in previous research that evidences the job insecurity of this group. However, research shows that this insecurity is due to the temporary nature of employment contracts for this group of workers. In Sweden, where temporary agency workers have the same type of employment contracts (i.e., temporary or permanent contracts and are entitled to the same employment protection as other groups of employees, one might expect a different picture. This article examines the situation of temporary agency workers who have the same working conditions as client organization employees. These workers have permanent contracts and are treated like client organization employees. We have chosen to examine this case because we anticipate it to be very likely to contradict statements regarding temporary agency workers’ affiliation with the precariat. This article aims to empirically elucidate the precariousness of temporary agency workers who are highly integrated with client organization employees and who share the same work tasks. Our analysis shows that competence development is crucial to perceptions of job security. However, temporary agency workers lack competence development, both on the part of the employer (the temporary work agency and on the part of the client organization. The client organization has no incentive to invest more than the required competencies, since temporary agency workers only constitute a buffer in case of a downturn. We argue that it is the agency workers’ connection with a buffer that results in a lack of job security. Our results also show that temporary agency workers’ job security could be increased if temporary agencies were to invest in competence development for the agency workers, thus overcoming these workers’ vulnerability in constituting a buffer.

    2012-09-15

    Alopecia after head and neck radiotherapy has been extensively reported in the literature. However, alopecia after endovascular procedures is seldom reported in the dermatological literature. Prolonged fluoroscopic imaging during these procedures may cause serious radiation injuries to the skin, such as dermatitis or alopecia. Radiation-induced temporary alopecia is a peculiar form of radiodermitis that occurs over the areas of the scalp that receive the highest doses of radiation. Although repopulation of alopecic patches occurs spontaneously without treatment, it is important to recognize this disorder to establish a correct diagnosis and inform patients about this transient side effect. We report a 44-year-old woman presenting with temporary alopecia after embolization of an arteriovenous malformation.

It is a synthesis between the ancient origami’s art and the innovative vacuumatics. So SETS is able to switch from two-dimensional configuration, for transportation and storage, to the spatial one, adaptable to several uses (from fashion shows to emergencies. To achieve this goal SETS is based on two qualifying items: a strong geometric control, due to the parametric design tool, and the vacuum technology, that is able to ‘freeze’ it into the chosen configuration. In this article the authors will describe the topics of the first steps of the research, that allowed them to make some physic model in scale. They will also show the program of the following phases, that are addressed to the building of a prototype.

  13. Temporary Life Changes and the Timing of Divorce.

    Science.gov (United States)

    Fallesen, Peter; Breen, Richard

    2016-10-01

    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.

The level of morbidity with temporary disability (MWTD in 100 operating reserve (retired officers amounted to 94 cases. The number of days of temporary disability was equal to 867 days per 100 employed military pensioners. Most long-term treatment (up to 47 days were required for patients with blood diseases. Analysis of the structure of diseases of reserve (retired officers leading to temporary disability, showed that the bulk of the cases (63.7 per cent were diseases of the respiratory organs, in second place were diseases of the circulatory system (24,5%, the third — diseases of the genitourinary system (4.3%. The average number of existing diseases to working military retirees less than idle: 1.9 vs 2.1. The average number of diseases at the single soldiers discharged was significantly more than that of living in family.Conclusion. The features of level and structure, as well as risk factors of MWTD should be considered in the development and adoption of administrative decisions directed on preservation and strengthening of health of reserve (retired officers.

    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,...

  17. Nursing procedure in the temporary transvenous pacemaker implantation

    Directory of Open Access Journals (Sweden)

    Mª Teresa Redecillas Peiró

    2013-05-01

    Full Text Available The temporary transvenous pacemaker (MPTT implantation is a technique that consists in stimulating artificially the heart when the natural pacemaker is unable to maintain the rhythm and the appropiate frequency. This type of electric stimulation is carried out by means of an electrocateter that was implanted in the endocardium through a central vein connected to an external generator, requiring equipment and personal with specific abilities. It is commonly carried out in the intensive care units when a continuous temporary stimulation is suitable and in most cases it is carried out in situations of extreme medical urgency in critical and unstable patients. The nursing professionals play an important role in the whole procedure, becoming essential that they possess knowledge not only about technique and handling of the device but also on the performance in all its phases. This research work intends to be a practical reference that gathers those essential aspects for the development of this assistance practice including, in a detailed way, the nursing performance in the preparation, the implantation and the pursuit of the patients who a temporary transvenous pacemaker was placed in.

  18. 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.

    2005-01-01

    The purpose of this retrospective study was to determine if immediate placement of a stainless steel crown (SSC) after emergency pulpotomies in primary molars would result in a better outcome when compared to different temporary restorations. Records of 94 emergency pulpotomies in primary molars performed at a university pediatric graduate dental clinic between July 2001 and June 2004 were analyzed. Inclusion criteria included: (1) teeth with a positive history of spontaneous or elicited pain; (2) deep caries with close approximation to the pulp; (3) absence of clinical and radiographic signs of pulpal degeneration; (4) abnormal mobility; or (5) swelling. Pulpotomized teeth were temporarily restored with a zinc oxide eugenol-based temporary restoration (IRM) covered with Ketac Molar or with a permanent restoration (SSC). The time interval between emergency and definitive treatment or recall, age, gender, tooth type, and arch were the variables analyzed in the study. Success was determined by record (progress notes and radiographs) verification of SSC placement in case of a temporary restoration and by confirmation of crown presence during recall exam. Data from emergency pulpotomies restored only with IRM was added to the study and included in the statistical analysis. Superior clinical success was obtained when emergency pulpotomies were restored with SSC (86%) when compared to IRM only (61%) or IRM and Ketac Molar combined (77%). Statistical significance was obtained in favor of SSC when survival analysis was performed (P.05). Immediate placement of an SSC tended to improve the chances for success when emergency pulpotomies are performed.

    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.

    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.

    Medical school faculty members are charged with the critical responsibility of preparing the future physician and medical scientist workforce. Recent reports suggest that medical school curricula have not kept pace with societal needs and that medical schools are graduating students who lack the knowledge and skills needed to practice effectively in the 21st century. The majority of faculty members want to be effective teachers and graduate well-prepared medical students, but multiple and complex factors-curricular, cultural, environmental, and financial-impede their efforts. Curricular impediments to effective teaching include unclear definitions of and disagreement on learning needs, misunderstood or unstated goals and objectives, and curriculum sequencing challenges. Student and faculty attitudes, too few faculty development opportunities, and the lack of an award system for teaching all are major culture-based barriers. Environmental barriers, such as time limitations, the setting, and the physical space in which medical education takes place, and financial barriers, such as limited education budgets, also pose serious challenges to even the most committed teachers. This article delineates the barriers to effective teaching as noted in the literature and recommends action items, some of which are incremental whereas others represent major change. Physicians-in-training, medical faculty, and society are depending on medical education leaders to address these barriers to effect the changes needed to enhance teaching and learning. © by the Association of American Medical Colleges.

    Recent studies about the cutaneous barrier demonstrated consistent evidence that the stratum corneum is a metabolically active structure and also has adaptive functions, may play a regulatory role in the inflammatory response with activation of keratinocytes, angiogenesis and fibroplasia, whose intensity depends primarily on the intensity the stimulus. There are few studies investigating the abnormalities of the skin barrier in rosacea, but the existing data already show that there are changes resulting from inflammation, which can generate a vicious circle caused a prolongation of flare-ups and worsening of symptoms. This article aims to gather the most relevant literature data about the characteristics and effects of the state of the skin barrier in rosacea. PMID:26982780

    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.

    The extraction of representations of the fusion barrier distribution from backward-angle, quasi-elastic, elastic and transfer excitation functions is discussed. Such excitation functions have been measured for {sup 16}O, {sup 32}S and {sup 40}Ca projectiles incident on a variety of targets. The results are compared with representations obtained from fusion excitation functions. Varying in their sensitivity, all representations show evidence of the barrier structure. Differences between the scattering and the fusion representations can be related to the effects of coupling to residual, weak reaction channels. (author)

    2017-10-26

    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.

    Full Text Available Khalid H Zawawi Department of Orthodontics, Faculty of Dentistry, King Abdulaziz University, Jeddah, Saudi Arabia Objective: To study the patient’s acceptance, expectation, and experience of pain with ­orthodontic temporary miniscrews. Methods: Questionnaires were distributed to 165 potential temporary orthodontic miniscrew recipients or their parents. Using the numeric rating scale, patients who received miniscrews as part of their orthodontic treatment were also asked to rate the pain or discomfort experience after miniscrew placement.Results: A total of 165 subjects completed the first set of questions. There was a significant relationship between level of education and prior knowledge about orthodontic miniscrews (P=0.029. Even though only 12.7% had heard about miniscrews, 82.4% agreed to have miniscrews placed to facilitate orthodontic tooth movement. Eighty-three subjects who needed miniscrews as part of their orthodontic treatment completed two more sets of questions after 6 and 24 hours of miniscrew insertion. After 6 hours of miniscrew insertion, there was a significant difference in pain perception between men (mean =2.6±2.2 and women (mean =2.1±1.5; P=0.03. After 24 hours, there was no difference between men (0.2±0.4 and women (0.2±0.5; P>0.05. Postplacement, 32.5% did not require any pain medication, while 59.1% required a single dose and only 8.4% required two doses. A total of 76 patients (91.6% said that they would recommend this procedure.Conclusion: Patients do accept miniscrew as a treatment option in orthodontics. Postoperative pain is significantly low. The acceptance of miniscrews was not related to patient’s previous knowledge of the device, and patients preferred miniscrews to extractions.

    The aim of this study is to evaluate the in vitro response of human gingival fibroblasts in primary cultures to two materials for temporary relining of dentures: Temporary Soft (TDV, Brazil) and Trusoft (Bosworth, USA) for 24 hours, 7 and 30 days by using a multi-parametric analysis. Each material sample (TDV, TS, Polystyrene, Latex) was prepared and incubated in a culture medium for 1, 7, and 30 days at 37°C. Human gingival fibroblasts were exposed to the extracts and cell viability was evaluated by a multi-parametric assay, which allowed sequential analysis of mitochondrial activity (XTT), membrane integrity [neutral red (NR)], and cell density [crystal violet dye exclusion (CVDE)] in the same cells. Analysis of variance (ANOVA) was used to test the interactions of the three sources of variation (material, test method, and time) with the proportions of viable cells for each relining material. Both evaluated materials (TDV and TS) had low cytotoxic effects during 1, 7, and 30 days after manipulation of the material, as assessed by all three methods used. A statistical difference was found when comparing the negative control group (latex fragments) with the other groups, which showed high toxicity and low percentage of cell viability in all tests used. There was no significant difference among other materials (p > 0.05). Low cytotoxicity levels were detected by representatives of the major groups of temporary prosthetic relining materials, as evaluated by multiple cellular viability parameters in human fibroblasts. There are various soft materials on the market for relining prostheses; however, the effects of these materials on tissues need to be clarified to avoid problems for patients.

    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

    The aim of this study was to compare the sealing properties of IRM, Coltosol, Cavit G, Adhesor and Clip, which used as temporary filling material in coronal access openings in extracted human primary teeth. Standardized access cavities of 2 x 2 mm were prepared in the eighty-four, caries-free human primary anterior teeth. The teeth were divided randomly into five groups of 16 teeth each. Temporary restorative materials Group A: IRM (Dentsply), Group B: Coltosol (Coltone), Group C: Cavit G (3M), Group D: Adhesor (Spofa Dental) and Group E: Clip (Voco) were applied according to the manufacturer's directions. The specimens were immersed silver nitrate and placed in film developer under fluorescent for 24 hours. The sectioned specimens were evaluated under a digital microscope at x 20 magnifications and blindly scored for microleakage. Clip presented the least microleakage value whereas; Adhesor and IRM presented the higher microleakage values. There were statistically significant differences between Clip and the others groups, while there were no statistically significant differences in microleakage between IRM, Adhesor, Coltosol and Cavit G. However the leakage scores of Clip and Cavit G were congruent (p = 0.454). Amongst the five materials, Clip exhibited a better sealing ability.

    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.

  1. The profound precariousness of work through temporary work agency

    Mihaela-Emilia Marica

    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.

    Schreiber, Lukas; Franke, Rochus Benni; Geldner, Niko; Reina-Pinto, José J.; Kunst, Ljerka

    2013-01-01

    During the development of Arabidopsis and other land plants, diffusion barriers are formed in the apoplast of specialized tissues within a variety of plant organs. While the cuticle of the epidermis is the primary diffusion barrier in the shoot, the Casparian strips and suberin lamellae of the endodermis and the periderm represent the diffusion barriers in the root. Different classes of molecules contribute to the formation of extracellular diffusion barriers in an organ- and tissue-specific manner. Cutin and wax are the major components of the cuticle, lignin forms the early Casparian strip, and suberin is deposited in the stage II endodermis and the periderm. The current status of our understanding of the relationships between the chemical structure, ultrastructure and physiological functions of plant diffusion barriers is discussed. Specific aspects of the synthesis of diffusion barrier components and protocols that can be used for the assessment of barrier function and important barrier properties are also presented.

    To examine the nature and prevalence of the use of temporary nursing staff in intensive care units and relationships between the use of temporary nursing staff and the occurrence of nosocomial infections (central line-associated blood stream infections and ventilator-associated pneumonia). Hiring temporary nurses raises controversial issues with respect to nurse staffing, care processes and patient outcomes, yet empirical findings regarding the use of temporary nurses are mixed. Whether adverse patient outcomes in intensive care units are related to the use of temporary nursing staff remains unexamined. A retrospective longitudinal design was used. Data were collected monthly from 12 intensive care units at six hospitals; 144 ICU-month data points were used for the analysis. Chi-square, anova and logit regression models were used to examine the research questions. The intensive care units used higher levels of temporary nursing staff, but the use of temporary nursing staff was not significantly associated with nosocomial infections. Nurses' perceptions regarding staffing and resource adequacy were significantly associated with nosocomial infections. No evidence was found to link the use of temporary nursing staff and nosocomial infections. Instead, nurses' perceptions of staffing adequacy were related to nosocomial infections. Given the greater use of temporary nursing staff in intensive care units, nurse managers in intensive care units need to monitor the levels of temporary nurse staffing and develop a systematic approach for hospitals to assist in these nurses' adjustment, which can reduce the burden of both temporary and permanent intensive care unit nurses. In addition to quantitative measures of nurse staffing, nurses' perceptions regarding staffing adequacy can be used to measure nurse staffing in relation to adverse patient outcomes. © 2014 John Wiley & Sons Ltd.

  10. 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.

  11. Evaluation Of A Temporary, Immersive Learning Community Based On Worldschooling

    Directory of Open Access Journals (Sweden)

    Aimee FERRARO

    2016-12-01

    Full Text Available Learning communities are a proven method for engaging groups of people who share common goals for personal growth and knowledge acquisition (Gabelnick, MacGregor, Matthews, & Smith, 1990; Taylor, Moore, MacGregor, & Lindblad, 2003. However, little is known about the usefulness of this approach in the context of alternative education. This article describes the evaluation of a temporary, immersive learning community for self-directed teen learners, Project World School (PWS, which was based on a new, pedagogical approach to learning called worldschooling. Findings indicate that regardless of demographic characteristics and personal interests, PWS attendees experienced learning and progress in three main areas: social development, personal development, and experiential academics. The PWS model shows evidence of the benefits of worldschooling and has potential to be successfully replicated and translated to other international settings.

  12. 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.

    2009-11-01

    This study was conducted to describe and compare empowerment, job satisfaction, and organizational commitment between permanent and temporary nurses in Korea. Since Korea's economic crisis of 1997, Korea's labor market has been undergoing dramatic modification, and the rate of temporary nurses employed in health care organizations has gradually increased. However, studies focusing on nurses' employment status, which potentially affect the individual and hospital organization, have been rarely conducted. This was a descriptive comparative study. The convenient sample of 416 nurses from 19 hospitals in Korea completed a structured questionnaire. Overall, permanent nurses presented higher levels of job satisfaction, organizational commitment, and empowerment than did temporary nurses. The results of this study indicated that health care administrators should develop strategies to close the gap of perceptions between permanent and temporary nurses in Korea. The results of this study also imply that such opportunities and compensation plans related with administrative recognition should be made available to the temporary nurses to manage their workforces more efficiently.

  15. 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.

  16. 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.

  17. Temporary ectropion therapy by adhesive taping: a case study

    Directory of Open Access Journals (Sweden)

    Habermann Anke

    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.

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

    Gallart, Francesc; Llorens, Pilar; Cid, Núria; latron, Jérôme; Bonada, Núria; Prat, Narcís

    2017-04-01

    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. [Barrier methods of contraception].

    Goldsmith, A; Edelman, D A

    1982-01-01

    Vaginal methods of contraception were the earliest types used and some references to them date back to antiquity. Most of the vaginal contraceptive agents identified by the ancient Greeks, Indians, Japanese, and Chinese have been found in modern laboratory tests to have spermicidal properties, but it is doubtful that the methods were fully reliable or were used by many people. During the 19th century the condom, vaginal spermicides, and diaphragm became available. The development of nonoxynol-9 and other nonirritating but effective spermicidal agents improved vaginal contraceptives greatly by the 1950s, but starting in the 1960s newer methods began to replace the vaginal methods. Interest in barrier methods has been reawakened somewhat by concern about the health effects of hormonal methods. At present all barrier methods leave something to be desired. Failure rates of 3-30% for barrier methods in general have been estimated, but the higher rates are believed due to incorrect or inconsistent use. Theoretical failure rates of condoms and diaphragms have been estimated at 3/100 women-years, but in actual use failure rates may reach 15 for condoms and 13 for diaphragms used with spermicides. Use-effectiveness rates are greatly influenced by motivation. For a variety of reasons, the acceptability of barrier methods is low, especially in developing countries. New developments in spermicidal agents include sperm inhibitors, which impede the fertilizing capacity of sperm rather than attempting a spermicidal effect; a number of such agents have been studied and have proven more effective in animal tests than conventional spermicides. Neosampoon, a new spermicidal foam, has attracted an increasing number of users, especially in developing countries. A new condom, made of thin polymers and containing a standard dose of nonoxynol-9, has been designed to dissolve in the vaginal fluid. Further studies are needed of its acceptability, efficacy, and side effects before it becomes

  20. 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

  1. Indoor air quality and thermal comfort in temporary houses occupied after the Great East Japan Earthquake.

    Thermal conditions and indoor concentrations of aldehydes, volatile organic compounds (VOCs), and NO2 were investigated in 19 occupied temporary houses in 15 temporary housing estates constructed in Minamisoma City, Fukushima, Japan. The data were collected in winter, spring, and summer in January to July 2012. Thermal conditions in temporary log houses in the summer were more comfortable than those in pre-fabricated houses. In the winter, the indoor temperature was uncomfortably low in all of the houses, particularly the temporary log houses. Indoor air concentrations for most aldehydes and VOCs were much lower than the indoor guidelines, except for those of p-dichlorobenzene, acetaldehyde, and total VOCs. The indoor p-dichlorobenzene concentrations exceeded the guideline (240 μg/m(3)) in 18% of the temporary houses, and the 10(-3) cancer risk level (91 μg/m(3)) was exceeded in winter in 21% due to use of moth repellents by the occupants. Indoor acetaldehyde concentrations exceeded the guideline (48 μg/m(3) ) in about half of the temporary houses, likely originating from the wooden building materials. Indoor NO2 concentrations in the temporary houses were significantly higher in houses where combustion heating appliances were used (0.17 ± 0.11 ppm) than in those where they were not used (0.0094 ± 0.0065 ppm). In the winter, log-house-type temporary houses are comfortable in terms of humidity, dew condensation, and fungi based on the results of questionnaires and measurements, whereas pre-fabricated temporary houses are more comfortable in terms of temperature. In the summer, log-house-type temporary houses are comfortable in terms of temperature and humidity. More comfortable temporary housing in terms of temperature and humidity year-round is needed. Indoor air concentrations of p-dichlorobenzene and NO2 were quite high in some temporary houses due to occupants’ activities, such as use of moth repellents and combustion heating appliances.

    Radiofrequency (RF) technology has improved detection of retained surgical sponges with a reported 100% sensitivity and specificity. However, the potential for interactions of the RF signals emitted by the detection system with cardiac implantable electronic devices (CIEDs) or temporary pacemakers may limit its use in those patients with these devices. This study investigated whether RF detection technology causes interference or clinically significant changes in the programmed settings of implanted pacemakers and defibrillators or temporary epicardial pacemakers. Fifty patients who were scheduled either for CIED removal or placement of a temporary epicardial pacemaker (at the time of open heart surgery) were recruited for this study. Device settings and measurements from separate interrogations before and after scanning with the RF detection system were compared. For the temporary pacemakers, we observed for any changes in hemodynamics or signs of pacing interference. Twenty (40%) pacemakers, 20 (40%) implantable cardioverter defibrillators, and 10 (20%) temporary pacemakers were analyzed in this study. During scanning, no signal interference was detected in any permanent device, and there were no significant changes in programmed settings after scanning with the RF detection system. However, pacing inhibition was detected with temporary pacing systems when programmed to a synchronous mode (DDD). RF detection technology can be safely used to scan for retained surgical sponges in patients with permanent CIEDs and temporary pacemakers set to asynchronous mode. © 2016 Wiley Periodicals, Inc.

  6. Review of the Potential for a Cyber-Physical System Approach to Temporary Structures Monitoring

    Full Text Available Around three quarters of construction workers work on or near temporary structures, whose failures lead to more than 100 deaths, 4500 injuries, and damage costing $90 million each year in the United States. However, few of the temporary structural problems have been well addressed, especially when compared with the increasing improvements in permanent structures. Meanwhile, the review of leading causes of temporary structural failures identifies the need for improved methods, such as Cyber-Physical Systems (CPS, to prevent potential structural hazards. This paper makes the first effort to examine CPS applicability in temporary structures, and potential benefits brought by CPS to temporary structural monitoring. Key definitions and features of CPS, CPS applications in both other industry sectors and the built environment, and applications of CPS enabling technologies in temporary structures are reviewed. It is concluded that CPS provides opportunity to address safety and structural problems of temporary structures. For a clear understanding of how CPS works in structural monitoring, an application scenario of scaffolding system is presented. Finally, system requirements followed by a system architecture are identified.

  7. Countermeasures and barriers

    In 1973 Haddon proposed ten strategies for reducing and avoiding damages based on a model of potential harmful energy transfer (Haddon, 1973). The strategies apply to a large variety of unwanted phenomena. Haddon's pioneering work on countermeasures has had a major influence on later thinking about safety. Considering its impact it is remarkable that the literature offers almost no discussions related to the theoretical foundations of Haddon's countermeasure strategies. The present report addresses a number of theoretical issues related to Haddon's countermeasure strategies, which are: 1) A reformulation and formalization of Haddon's countermeasure strategies. 2) An identification and description of some of the problems associated with the term 'barrier'. 3) Suggestions for a more precise terminology based on the causal structure of countermeasures. 4) Extending the scope of countermeasures to include sign-based countermeasures.

    Adverse events can occur after rabies post-exposure prophylaxis (PEP), and linkage to causality is often difficult to determine. We report a case of recurrent temporary paralysis that began immediately after the initiation of rabies PEP in a man exposed to a bat. The recurrent temporary paralysis first occurred in the patient after his initial dose and then again after day 3 of his rabies PEP. The PEP was terminated prior to a serologic response. The patient continued to experience numerous discrete episodes of temporary paralysis for over two years. © 2014 Blackwell Verlag GmbH.

    The use of removable provisional prosthesis after implant placement is undesirable for many patients. In addition, removable prostheses place unfavorable pressure over implants during the healing period. The use of temporary implants enable greater stability and functionality of the prostheses. This clinical report shows the use of temporary implants in a low density maxilla in conjunction with a fixed provisional prosthesis. The temporary implants contributed to the support of the provisional fixed upper arch prosthesis and to patient comfort with a fixed prosthesis during the healing period.   Fixed provisional prostheses are a potentially desirable alternative treatment strategy. © 2009 Wiley Periodicals, Inc.

    Full Text Available 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.

  11. Homogeneous Reactor Experiment (HRE) Pond cryogenic barrier technology demonstration: Pre-barrier subsurface hydrology and contaminant transport investigation

    Energy Technology Data Exchange (ETDEWEB)

    Moline, G.R.

    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 {sup 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 aim of this paper is to evaluate the role of intervening obstacles, understood as legal and policy barriers blocking immigrant access to foreign labor markets, in the international migration process. To do so, we use Polish international temporary emigrants in the years 2000-2012, which spans both the pre-accession period, when Polish citizens were not entitled to access other EU labor markets, as well as the post - accession period, when certain countries gradually removed intervening obstacles according to the transnational agreements.

    1989-12-01

    In 1986 the Third National Survey on Contraceptive Prevalence took place in Colombia. The results of this article are based on the CPR of Colombia's Atlantic Coast. The information demonstrated the high prevalence of female sterilization in the area, but also the lowest CPR among temporary methods. As a result of these outcomes PROFAMILIA, along with The Futures Group/SOMARC and Johns Hopkins University launched a promotional campaign in the Atlantic Region to increase the CPR. However, prior to the campaign, PROFAMILIA instituted 2 surveys to collect baseline data for the promotional campaign. The initial KAP survey was the 1st of its kind in the Atlantic Coast directed at men (15-59) and women (15-49) in fertile ages; while the 2nd KAP survey was directed at the pharmacists in the region. Focus groups were organized to determine attitudes and practices of individual men and women in the area. The social marketing of condoms and orals took place because of the attitudes of men and women towards childbearing. Most women wanted to have their children quickly followed by getting "disconnected" from childbearing through sterilization. While they are having children, they need the pill to properly space each birth. The outcomes of marketing these 2 methods demonstrated that condoms were easier to market than the pill.

  14. Virtual planning for vertical control using temporary anchorage devices

    Full Text Available The new and innovative technologies are unprecedentedly improving the level of proficiency in orthodontics in the recent history of this area of expertise. The proliferation of advances, such as self-ligating systems, temporary anchorage devices, shape-memory wires, robotically wire bending, intraoral scanners, cone-beam computed tomography, bring the virtual planning, and confection of dental devices through CAD/CAM systems to the real world. In order to get efficiency and efficacy in orthodontics with these new technologies, we must understand the importance of systemically managed clinical information, medical, and dentistry history of the patients, including the images resources, which ensures the use of a communication that is assisted by the technology, with an interdisciplinary team so that the database is able to help and support the process of therapeutic decision-making. This paper presents the clinical case of a borderline patient for orthognathic surgery who had his final treatment planning supported by these new tools for three-dimensional diagnosis and virtual planning.

  15. Open bite treated with extractions and temporary anchorage devices

    2017-01-01

    Full Text Available A 13-year-old female with a chief complaint of continuing treatment presented with Class I skeletal pattern and slight facial asymmetry. Intraorally, she had Class II molar relationship on the right side, class l on the left side and 3mm. of midline discrepancy. Her upper and lower incisors were proclined and slightly crowded. She had 1 mm. overbite and 5mm. overjet in initial mounted casts. Splint therapy was suggested to stabilize mandibular position. After splint wear, a new mounting was made, which resulted in an open bite from left second molars to right second molars. A visual treatment objective was prepared with four first bicuspid extractions. After 9 months, upper second molars were extracted and temporary anchorage devices (TADs were placed in the upper arch for intrusion. Detailing strategies such as bracket repositioning, occlusal adjustment, and elastics were used. The role of segmented models, second molar extraction treatment, and superimposition analysis in patients with discrepancies in mandibular position is discussed. It is concluded that a thorough case workup is needed to provide patients with a successful treatment for open bite cases. This case was treated orthodontically in 2 years with four bicuspid and upper second molar extractions as well as vertical control with TADs.

    2007-06-15

    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.)

  2. K Basins sludge removal temporary sludge storage tank system

    Energy Technology Data Exchange (ETDEWEB)

    Mclean, M.A.

    1997-06-12

    Shipment of sludge from the K Basins to a disposal site is now targeted for August 2000. The current path forward for sludge disposal is shipment to Tank AW-105 in the Tank Waste Remediation System (TWRS). Significant issues of the feasibility of this path exist primarily due to criticality concerns and the presence of polychlorinated biphenyls (PCBS) in the sludge at levels that trigger regulation under the Toxic Substance Control Act. Introduction of PCBs into the TWRS processes could potentially involve significant design and operational impacts to both the Spent Nuclear Fuel and TWRS projects if technical and regulatory issues related to PCB treatment cannot be satisfactorily resolved. Concerns of meeting the TWRS acceptance criteria have evolved such that new storage tanks for the K Basins sludge may be the best option for storage prior to vitrification of the sludge. A reconunendation for the final disposition of the sludge is scheduled for June 30, 1997. To support this decision process, this project was developed. This project provides a preconceptual design package including preconceptual designs and cost estimates for the temporary sludge storage tanks. Development of cost estimates for the design and construction of sludge storage systems is required to help evaluate a recommendation for the final disposition of the K Basin sludge.

  3. Proposed Measures to Protect Temporary Roofs from Unwanted Heat Gains

    Directory of Open Access Journals (Sweden)

    Omar S. Asfour

    2017-06-01

    Full Text Available This study focuses on the uncompleted multi-storey residential buildings located in hot climates. This construction pattern is common in the case of incremental housing, where additional floors are added to the building as housing needs grow. Top roofs in these buildings are usually left without thermal insulation until the rest of upper floors are erected. This causes higher thermal discomfort in the top flats compared to the lower ones. Thus, the aim of this study is to investigate thermal effect of some proposed temporary measures that are intended to protect these roofs from unwanted heat gains until the rest of storeys are constructed. This has been carried out using thermal modelling to find out the effect of these measures on the amount of heat transfer through the roof in both summer and winter times. The analysis showed that it is possible to achieve competent thermal protection of the top roof compared to the layered thermal insulation using simple, cost-effective, and reversible measures. Among the examined measures, covering the roof with white foldable sheets and the use of pergolas have been found to be the most effective measures. In both cases, a reduction of 38% in conductive heat transfer through the top roof in summer was observed compared to the unprotected modelling case.

  5. Epistemological barriers to radical behaviorism.

    Science.gov (United States)

    O'Donohue, W T; Callaghan, G M; Ruckstuhl, L E

    1998-01-01

    The historian and philosopher of science Gaston Bachelard proposed the concept of epistemological barriers to describe the intellectual challenges encountered by scientists in their work. In order to embrace novel ways of approaching a problem in science, scientists must overcome barriers or obstacles posed by their prior views. For example, Einsteinian physics presents scientists with claims that space is curved and that time and space are on the same continuum. We utilize Bachelard's concept of epistemological barriers to describe the differences between the intellectual journeys students pursuing advanced studies face when attempting to accept cognitive psychology or radical behaviorism. We contend that the folk psychological beliefs that students typically hold when entering these studies pose less challenge to cognitive psychology than to radical behaviorism. We also suggest that these barriers may also partly be involved in the problematic exegesis that has plagued radical behaviorism. In close, we offer some suggestions for dealing with these epistemological barriers.

  6. Embryonic Blood-Cerebrospinal Fluid Barrier Formation and Function

    Directory of Open Access Journals (Sweden)

    2014-10-01

    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.

    2017-08-01

    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.

    The increasing use of temporary agency work in Germany has implications for the nature of the employment relationship. The notion of a clearly defined employeremployee relationship becomes difficult to uphold in triangular relationships like in the case of temporary agency work where the agencies employees are working at the site of the client company. The blurring of the boundaries of organisations and of the employment relationship leads to ambiguities that affect Human Resource Management....

    2008-01-01

    This report describes the temporary fixation of a traumatic shoulder luxation in a large-breed dog using a 3.5-mm Locking Round-Hole Reconstruction Plate (LRHRP) to provide stable internal splinting, allowing healing of the injured ligaments, joint capsule, glenohumeral ligaments, tendons, and muscles for restoration of joint stability. The use of a temporary plate with a locking system should be considered as an option in the treatment of canine shoulder joint luxations with severe tissue damage.

    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.

    Full Text Available Russia had few temporary workers in the 1990s, but after the fall of the Soviet Union and the entrance of foreign MNCs, the percent of workers on temporary contracts grew in 2014. In 2016, a new law was implemented that bans hiring temporary workers except through government-accredited agencies, but only for the purpose of substituting for employees who are temporarily absent from the workplace; to assist in the temporary expansion of production or services (for up to a maximum of nine months; and to provide temporary employment to certain approved categories of workers (i.e., fulltime students, single parents, parents of multiple children, and former convicts.This paper will compare and contrast the current labor protections of temporary dispatch workers in the U.S. and Russia, with consideration also of the recent legislative labor protections provided in the East Asian countries of China, South Korea, and Japan.Following the Introduction, the paper, in Part I discusses the phenomena of “fissurization,” in employment relations and its resulting legal implications for the regulation of “dispatch (agency” workers in the above countries. Part II compares and contrasts the regulatory approaches of the U.S. with Russia and the East Asian countries of China, Japan, and South Korea; and the Conclusion follows. Perhaps the menu of regulatory legislation provided in this paper will be useful for those looking for the tools to construct dispatch regulation in the U.S.

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

    Directory of Open Access Journals (Sweden)

    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.

    Objective To evaluate the clinical outcome of a new sutureless approach for a temporary amniotic membrane patch (ProKera; Bio-Tissue, Inc, Miami, Florida) in eyes with acute burns. Methods Retrospective review of 5 eyes of 5 patients with grades I to III acute alkaline burns, receiving ProKera insertion within 8 days of injury. Results These eyes had either total (2 cases) or extensive (60%–75%, 3 cases) corneal epithelial defects with limbal (120°–360°) and conjunctival (30%–60%) epithelial defects. ProKera was inserted within a mean (SD) of 3.7 (3.1) days after burn and repeated 1 to 3 times for 3 cases. Conjunctival defects reepithelialized in 8.2 (5) days (range, 5–17 days), while limbal and corneal defects healed in 13.6 (8.3) days (range, 5–25 days). The latter was completed with circumferential closure of limbal defects followed by centripetal healing of corneal defects. In 3 eyes, early peripheral corneal neovascularization was followed by marked regression on completion of healing. During 16.8 (10.8) months of follow-up, all eyes retained a stable surface with improved corneal clarity, and without limbal deficiency or symblepharon. Conclusion This sutureless application of an amniotic membrane patch allows for early delivery of its biologic actions, which may help preserve remaining limbal stem cells for rapid expansion and prevent late cicatricial complications in eyes with mild and moderate acute alkaline burns.

    2016-01-01

    Background and Objectives Intolerance of uncertainty (IU) is a trans-diagnostic construct involved in anxiety and related disorders. Research focused on cross-sectional reporting, manipulating attitudes toward objective and impersonal events or on treatments designed to reduce IU in clinical populations. The current paper presents an experimental procedure for laboratory manipulations of IU and tests mediation hypotheses following the Intolerance of Uncertainty Model. Methods On pre-test, undergraduate volunteers (Study 1, n = 43;68% women. Study 2, n = 169;83.8% women) were asked to provide an idiosyncratic future negative life event. State-IU, Worry, Positive and Negative Affect were assessed after that a standardized procedure was used to identify event’s potential negative consequences. The same variables were assessed on post-test, after that participants were asked to read-through increasing and decreasing IU statements. Results Temporary changes on IU were consistently reproduced in both studies. Participants receiving increasing IU instructions reported greater state-IU, Worry and Negative Affect than those receiving decreasing IU instructions. However, this latter condition was not different from a control one (Study 2). Both studies revealed significant indirect effects of IU induction instructions on Worry and Negative Affect through state-IU. Limitations Both studies used undergraduate psychology students samples, younger than average population and predominantly female. Experimental manipulation and outcome measures belongs to the same semantic domain, uncertainty, potentially limiting generalizability. Conclusions Results supported the feasibility and efficacy of the proposed IU manipulation for non-clinical sample. Findings parallel clinical research showing that state-IU preceded Worry and Negative Affect states. PMID:27254099

    Temporary hemiepiphysiodesis (TH) with plate fixation is a well-accepted and common treatment for correcting leg malalignment in skeletally immature patients. The purpose of this study was to investigate any soft tissue damage caused during TH at the distal medial femur with a plate and two screws. We hypothesized that correct plate placement can affect the integrity of the medial stabilizing structures of the knee, especially the medial patellofemoral ligament (MPFL), the medial collateral ligament (MCL) or result in arthrotomy of the knee joint itself. In eight cadaveric knees of five adult humans a TH was performed with a plate and two cancellous screws at the distal medial femur using a standardized surgical technique. Subsequently the medial capsular and ligamentous structures were systematically exposed and assessed. Capsular and synovial tissue was also inspected for impingement by the plate or screws. In all knees the MPFL was present. In two specimens the MPFL was intact and the plate was lying over the dorsal part of the MPFL close to the MCL. The MPFL was completely cut in two cases in the central part of the ligament. In four cases the MPFL was partially dissected or perforated by a screw and fixed to the femur by the plate. The MCL was intact and not impinged by the implant in any case. In total four of eight knees the capsule was transected or perforated by a screw or by a part of the plate, resulting in intraarticular implant placement. Standard plate placement during TH on the distal medial femur frequently leads to damage to the MPFL, impingement of the MPFL, the capsular and synovial tissues or exposure of the knee joint.

    The aim of the survey was to obtain information on the treatment plan preferences, mechanics and characteristics of temporary anchorage device (TAD) application using a single case presented to orthodontists in Switzerland. A structured questionnaire to be completed by all study participants with case-specific (treatment plan including mechanics and TAD usage) and general questions (general fixed appliance and TAD usage as well as professional, educational and demographic questions) together with an orthodontic borderline case was utilised. The case was a female adult with dental Class II/2, deep bite and maxillary anterior crowing, who had been treated in childhood with extraction of four premolars and fixed appliance followed by wisdom tooth extraction. The response rate was 24.4% (108 out of 443). The majority (96.3%, 104) proposed comprehensive treatment, while 3.7% (4) planned only alignment of maxillary teeth. 8.3% (9) included a surgical approach in their treatment plan. An additional 0.9% (1) combined the surgical approach with Class II mechanics. 75.1% (81) decided on distalization on the maxilla using TADs, 7.4% (8) planned various types of Class II appliances and 3.7% (4) combined distalization using TADs or headgear with Class II appliances and surgery. Palatal implants were the most popular choice (70.6%, 60), followed by mini-screws (22.4%, 19) and mini-plates on the infrazygomatic crests (7.0%, 6). The preferred site of TAD insertion showed more variation in sagittal than in transversal dimension, and the median size of mini-screws used was 10.0-mm long (interquartile range (IQR) 2.3 mm) and 2.0-mm wide (IQR 0.3 mm). Distalization against palatal implants and then distalization against mini-screws were the most popular treatment plans. Preferred site for TAD insertion varied depending on type and size but varied more widely in the sagittal than in the transversal dimension.

  9. Modified sewage sludge as temporary landfill cover material

    Jun He

    2015-07-01

    Full Text Available In order to study the feasibility of modified sewage sludge as landfill cover material and its performance in a complex landfill environment, strength and hydraulic conductivity tests were conducted. The permeability requirements for daily and interim covers were analyzed first. Based on saturated-unsaturated seepage calculations, it is suggested that approximately 1.0 × 10−4 cm/s and 1.0 × 10−5 cm/s are the appropriate values for the hydraulic conductivities of daily and interim covers, respectively. The strength and permeability requirements of the mixtures, when used as an interim cover, can be met at a sludge:lime:cement:silt:tire-derived aggregate (TDA weight ratio of 100:15:5:70:15. Results also demonstrate that the solid content ratio of modified sewage sludge, which should be greater than 60% when modified sewage sludge is used as a temporary cover material, is crucial to both strength and hydraulic performance. In addition, as the duration of soaking of modified sewage sludge in synthetic leachate increases, the unconfined compressive strength increases, and the hydraulic conductivity decreases slightly or fluctuates between 1.0 × 10−5 cm/s and 1.0 × 10−6 cm/s, still meeting the requirements for an interim cover. The reduction in hydraulic conductivity of modified sewage sludge under the effect of synthetic leachate, as well as the long-term and environmental performance of the modified sewage sludge, should be examined in future studies.

  10. Barriers to organic milk production

    2012-01-01

    Full Text Available This paper describes barriers to production of the organic milk. There was conducted a survey among conventional producers of cow’s milk. Based on the identified barriers to organic milk production and farmers’ opinions on them there were identified the most important barriers. The most important barrier to the production of organic milk in Vysočina region is considered to be the lack of price premiums for organic milk produced. The price premium is currently around 0.40 CZK per litre of organic milk. Farmers require a minimum price premium 1 CZK per litre, respectively 30 % increase of the price of milk. The higher price premium may serve as a motivation, which could eliminate the second major barrier - satisfaction with the current production. Problematic contact with suppliers has been identified as the third most important barrier by surveyed firms. Buyers do not respect the agreed purchase price (premium price. Partial barrier to organic milk production, according to surveyed farmers is the lack of the necessary amount of concentrated feed in the quality of organic milk.

    The Great Barrier Reef extends for 2,000 kilometers along the northeastern coast of Australia. It is not a single reef, but a vast maze of reefs, passages, and coral cays (islands that are part of the reef). This nadir true-color image was acquired by the MISR instrument on August 26, 2000 (Terra orbit 3679), and shows part of the southern portion of the reef adjacent to the central Queensland coast. The width of the MISR swath is approximately 380 kilometers, with the reef clearly visible up to approximately 200 kilometers from the coast. It may be difficult to see the myriad details in the browse image, but if you retrieve the higher resolution version, a zoomed display reveals the spectacular structure of the many reefs.The more northerly coastal area in this image shows the vast extent of sugar cane cultivation, this being the largest sugar producing area in Australia, centered on the city of Mackay. Other industries in the area include coal, cattle, dairying, timber, grain, seafood, and fruit. The large island off the most northerly part of the coast visible in this image is Whitsunday Island, with smaller islands and reefs extending southeast, parallel to the coast. These include some of the better known resort islands such as Hayman, Lindeman, Hamilton, and Brampton Islands.Further south, just inland of the small semicircular bay near the right of the image, is Rockhampton, the largest city along the central Queensland coast, and the regional center for much of central Queensland. Rockhampton is just north of the Tropic of Capricorn. Its hinterland is a rich pastoral, agricultural, and mining region.MISR was built and is managed by NASA's Jet Propulsion Laboratory, Pasadena, CA, for NASA's Office of Earth Science, Washington, DC.

    To describe the design, implementation, and consumer response to a coupon-style intervention aimed to increase Supplemental Nutrition Assistance Program (SNAP) use at a farmers' market (FM) among Temporary Assistance for Needy Families (TANF) participants. A quasi-experimental trial to evaluate redemption response to 2 coupon interventions; baseline surveys characterized coupon redeemers and non-redeemers. Urban. The TANF recipients were assigned to either a plain (n = 124) or targeted marketing coupon intervention (n = 130). Both groups received 10 $2 coupons to double fruit and vegetable SNAP purchases at the FM. The targeted marketing group also received an oral presentation designed to reduce perceived barriers to FM use. Coupon redemption. The researchers used t tests and chi-square/Fisher exact tests to examine associations between redeemers and non-redeemers; logistic regression was used to adjust for the intervention. No male and few female participants redeemed coupons (6.3%). Among women, those with knowledge of vegetable preparation were 3 times more likely to redeem coupons than were those with little or no knowledge (odds ratio = 3.77; 95% confidence interval, 1.03-13.77). Stand-alone coupon incentive programs may not be a high-reach strategy for encouraging FM use among the population using TANF. Complementary strategies to build vegetable preparation knowledge and skills are needed. Copyright © 2017 Society for Nutrition Education and Behavior. Published by Elsevier Inc.

  14. Nature of "superluminal" barrier tunneling.

    Science.gov (United States)

    Winful, Herbert G

    2003-01-17

    We show that the distortionless tunneling of electromagnetic pulses through a barrier is a quasistatic process in which the slowly varying envelope of the incident pulse modulates the amplitude of a standing wave. For pulses longer than the barrier width, the barrier acts as a lumped element with respect to the pulse envelope. The envelopes of the transmitted and reflected fields can adiabatically follow the incident pulse with only a small delay that originates from energy storage. The theory presented here provides a physical explanation of the tunneling process and resolves the mystery of apparent superluminality.

    2017-02-01

    New types of geochemical barriers on which chemical elements are immobilized as a result of combined complex formation and precipitation of barely soluble mineral phases are examined. A significant concentration of major components (Fe, Al) forming more stable complexes than an immobilized component X in the material is a necessary condition for this type of geochemical barriers. Filtration of the solution through a geochemical barrier is accompanied by substitution of X in the complex with a major component. As a result, the activity of X in the free state increases, and one barely soluble mineral phase or another of the component X precipitates when the state of saturation is achieved.

    2014-01-01

    Barrier creams (BCs) represent devices aiming to protect the skin from contact with exogenous hazardous substances, especially under working conditions. By preventing penetration and absorption of contaminants, BCs are designed to reduce the risk of developing both irritant and allergic contact dermatitis. In fact, BCs should improve stratum corneum hydration as well as provide emolliency to maintain skin integrity and to restore and repair the epidermis barrier function. The formulation and ingredients of the available BCs vary widely, and thus the choice of a BC should depend on the kind of contaminants, occupational conditions, and skin dysfunction. Although BCs are commonly recommended to prevent occupational contact dermatitis, their real benefit remains controversial. The aims of this review are to help the choice of appropriate BCs and to analyze the actual effectiveness in maintaining an intact skin barrier, preventing contact dermatitis, and speeding up the healing of barrier-impaired skin.

  2. Is temporary employment damaging to health? A longitudinal study on Italian workers.

    Pirani, Elena; Salvini, Silvana

    2015-01-01

    Working conditions have changed dramatically over recent decades in all the countries of European Union: permanent full-time employment characterized by job security and a stable salary is replaced more and more by temporary work, apprenticeship contracts, casual jobs and part-time work. The consequences of these changes on the general well-being of workers and their health represent an increasingly important path of inquiry. We add to the debate by answering the question: are Italian workers on temporary contracts more likely to suffer from poor health than those with permanent jobs? Our analysis is based on a sample of men and women aged 16-64 coming from the Italian longitudinal survey 2007-2010 of the European Union Statistics on Income and Living Conditions. We use the method of inverse-probability-of-treatment weights to estimate the causal effect of temporary work on self-rated health, controlling for selection effects. Our major findings can be summarized as follows: firstly, we show a negative association between temporary employment and health that results from a statistical causal effect in the work-to-health direction, and does not trivially derive from a selection of healthier individuals in the group of people who find permanent jobs (selection effect). Secondly, we find that temporary employment becomes particularly negative for the individual's health when it is prolonged over time. Thirdly, whereas temporary employment does not entail significant adverse consequences for men, the link between temporary employment and health is strongly harmful for Italian women.

    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.

    Patients with rectal cancer who have a temporary ostomy report good quality of life despite identifying a number of stoma-related difficulties. This study aimed to qualitatively explore the experiences of patients with rectal cancer who have a temporary ileostomy to better understand the discordant findings of previous quantitative quality-of-life studies. We conducted in-depth qualitative interviews with patients with stage I to III rectal cancer who underwent sphincter-preserving surgery that resulted in a temporary ileostomy. Twenty-six patients (54% male, median age 54) participated. Sixty-five percent had stage III disease, and 88% received neoadjuvant therapy. Interviews examined preoperative expectations, overall experience, and stoma impact on quality of life. With the use of grounded theory, 2 investigators independently performed line-by-line content analysis to identify key themes. Analysis continued until data saturation. Two major themes were identified: stoma-related difficulties and perceived response shift. Patients reported difficulty in exercise, sleep, social activities, sexuality, and clothing. Patients' perception of quality of life with a temporary stoma appears to have undergone a response shift through recalibration of their standards for measuring quality of life (internal measurement scale altered by side effects of neoadjuvant/adjuvant treatment, temporary nature of stoma, and accommodation to stoma) and reconceptualization of what "good quality of life" is (stoma difficulties were felt to be less important in comparison with cancer-related mortality). Although qualitative research is, by design, not generalizable, these data support our previous quantitative work. This convergence of findings suggests that our data may be representative. A temporary ileostomy represents significant difficulties for patients with rectal cancer. However, because of response shift, these difficulties may not be perceived as important to overall quality of

    A system and method for generating global asynchronous signals in a computing structure. Particularly, a global interrupt and barrier network is implemented that implements logic for generating global interrupt and barrier signals for controlling global asynchronous operations performed by processing elements at selected processing nodes of a computing structure in accordance with a processing algorithm; and includes the physical interconnecting of the processing nodes for communicating the global interrupt and barrier signals to the elements via low-latency paths. The global asynchronous signals respectively initiate interrupt and barrier operations at the processing nodes at times selected for optimizing performance of the processing algorithms. In one embodiment, the global interrupt and barrier network is implemented in a scalable, massively parallel supercomputing device structure comprising a plurality of processing nodes interconnected by multiple independent networks, with each node including one or more processing elements for performing computation or communication activity as required when performing parallel algorithm operations. One multiple independent network includes a global tree network for enabling high-speed global tree communications among global tree network nodes or sub-trees thereof. The global interrupt and barrier network may operate in parallel with the global tree network for providing global asynchronous sideband signals.

    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.

    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

    2014-01-01

    Background The aim of the survey was to obtain information on the treatment plan preferences, mechanics and characteristics of temporary anchorage device (TAD) application using a single case presented to orthodontists in Switzerland. Methods A structured questionnaire to be completed by all study participants with case-specific (treatment plan including mechanics and TAD usage) and general questions (general fixed appliance and TAD usage as well as professional, educational and demographic questions) together with an orthodontic borderline case was utilised. The case was a female adult with dental Class II/2, deep bite and maxillary anterior crowing, who had been treated in childhood with extraction of four premolars and fixed appliance followed by wisdom tooth extraction. Results The response rate was 24.4% (108 out of 443). The majority (96.3%, 104) proposed comprehensive treatment, while 3.7% (4) planned only alignment of maxillary teeth. 8.3% (9) included a surgical approach in their treatment plan. An additional 0.9% (1) combined the surgical approach with Class II mechanics. 75.1% (81) decided on distalization on the maxilla using TADs, 7.4% (8) planned various types of Class II appliances and 3.7% (4) combined distalization using TADs or headgear with Class II appliances and surgery. Palatal implants were the most popular choice (70.6%, 60), followed by mini-screws (22.4%, 19) and mini-plates on the infrazygomatic crests (7.0%, 6). The preferred site of TAD insertion showed more variation in sagittal than in transversal dimension, and the median size of mini-screws used was 10.0-mm long (interquartile range (IQR) 2.3 mm) and 2.0-mm wide (IQR 0.3 mm). Conclusions Distalization against palatal implants and then distalization against mini-screws were the most popular treatment plans. Preferred site for TAD insertion varied depending on type and size but varied more widely in the sagittal than in the transversal dimension. PMID:24935644

    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

    Gelatine is a recognized tissue simulant in wound ballistic research. The deceleration of a bullet causes a temporary cavity which provokes radial fissures by stretching the gelatine. The evaluation of gelatine destruction was performed with very different methods yet, widely known are the wound profile by Fackler and the total crack length (TCL) method. Aims of the presented experimental study were to cover a wide range of kinetic bullet energy, to gather all destruction associated parameters and to correlate them to energy dissipation. According to recommendations of the Technical Guideline Commission of the German police and to Fackler, a 10% solution of Gelita Ballistic 3 gelatine was moulded in 20 cm × 20 cm × 50 cm dimensioned blocks. In the front of the blocks a 2 mm thin and 8 cm × 8 cm film bag containing about 8 g pasty acryl paint was integrated. The blocks were cooled to 4°C and were shot from a distance of 5m. The bullet's velocity was measured in front of the target. The expanding bullets Silvertip(®) (Winchester) und First Defense(®) (Magtech) were used. Varying calibres, loads and barrel lengths bullet velocities from 250 to 686 m/s were achieved while kinetic energy was spread from 71 up to 1450 J. All projectiles were captured in gelatine and had mushroomed, as expected. The blocks were freshly cut into 1cm-slices which were optically scanned. The evaluation was performed with AxioVision (Zeiss) software and in each slice the following parameters were taken: longest fissure radius, wound profile (addition of the two longest fissures), sum of the three longest cracks, TCL, perimeter and area of the polygon created by linking the fissure ends. All analyzed parameters - either crack length based methods (wound profile and the TCL) or destruction area based methods (polygon method) - showed a strong dependence of the gelatine destruction and the energy dissipated. This regularity could be approximated by linear function (correlation coefficient

    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.

    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.

    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.

    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.

    The purpose of this study was to evaluate the effect of either eugenol-containing or eugenol-free temporary cement removal by excavator or sandblasting on the shear bond strength of ceramic luted to dentin. A self-etching primer system, Panavia F 2.0, Kuraray Medical (PF2), and a total-etch bonding system, Excite/Variolink II, Vivadent (EXV), were used. One hundred and forty human molars, ground to expose dentin surfaces, were divided into 14 groups (seven groups for each adhesive system). For each adhesive system, either a eugenol-containing (Temp bond) or a eugenol-free (Temp bond NE) temporary cement was applied to the dentin surface for 7 days, then removed by an excavator or sandblasting (four groups). Three control groups were studied where fresh dentin was either scratched by excavator or sandblasted, or underwent no surface treatment. After application of the adhesives, ceramic cones (Cerafil inserts) were adhesively luted to standardized dentin areas. After 24 h storage in distilled water, the shear bond strengths were determined at a cross-head speed of 0.75 mm/min. For each adhesive system, neither the method of temporary cement removal nor the type of temporary cement affected the bond strength significantly (Pcements, either containing eugenol or not, does not alter the retentive strength of ceramic restorations luted to dentin using the tested adhesive systems, whether the temporary cements are removed by excavator or sandblasting.

    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.

    The number of temporary migrant workers from rural areas to urban areas in emerging market economies like China has increased dramatically since the early 1980s. Temporary migrant workers have been labeled as the major driving force for the rising incidence of infectious diseases in cities. However, it has not been well recognized that temporary migration indeed may have tremendous impacts on the spread of infectious diseases in migrants' home villages. In this paper, by proposing a delay differential equation model, we provide a framework to study the influence of temporary migration on the transmission of infectious diseases in a migrant workers' home village. The model is shown to admit a unique positive equilibrium which is locally asymptotically stable and is globally asymptotically stable under certain conditions. This implies that the disease always persists at a constant level. Considering tuberculosis as an example, we explore various disease prevention and control strategies numerically to demonstrate how migration related parameters affect the early outbreak of the disease. We find that a single control strategy, such as reducing the migration time period alone, has little effect on reducing the disease endemic level. For disease prevention and control, temporary migrant workers should be identified as the top target group, and a combination of several prevention strategies should be implemented.

    The insertion of temporary hemodialysis catheters is considered to be a core competency of nephrology fellowship training. Little is known about the adequacy of training for this procedure and the extent to which evidence-based techniques to reduce complications have been adopted. We conducted a web-based survey of Canadian nephrology trainees regarding the insertion of temporary hemodialysis catheters. Responses were received from 45 of 68 (66%) eligible trainees. The median number of temporary hemodialysis catheters inserted during the prior 6 months of training was 5 (IQR, 2-11), with 9 (20%) trainees reporting they had inserted none. More than one-third of respondents indicated that they were not adequately trained to competently insert temporary hemodialysis catheters at both the femoral and internal jugular sites. These findings are relevant to a discussion of the current adequacy of procedural skills training during nephrology fellowship. With respect to temporary hemodialysis catheter placement, there is an opportunity for increased use of simulation-based teaching by training programs. Certain infection control techniques and use of real-time ultrasound should be more widely adopted. Consideration should be given to the establishment of minimum procedural training requirements at the level of both individual training programs and nationwide certification authorities.

    2013-05-01

    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.

    Progressing biological evolution is discussed in the framework of nonequilibrium thermodynamics. It is connected with an increase of the mass specific standard metabolism given by coefficient a in the allometric relation (1) between oxygen consumption rate and body mass of an animal. Three “heat barriers” are found in the course of such a bioenergetic evolution. The first heat barrier concerns an animal's overheating during active movement and is overcome by the development of thermoregulation and the appearance of homeothermic animals. A second barrier arises when the coefficient a reaches values connected with lethal body temperatures. The transition across this second heat barrier occurs as result of reasonable activities and the appearance of civilization. The third heat barrier will arise during the further development of human civilization, connected with a highly increased energy production and a fatal warming of the Earth atmosphere. The manner to overcome this barrier will probably depend on the assimilation of space and the establishment of energy consuming industries outside the Earth. The bioenergetic evolution discussed in this paper does not exclude other trends of evolution, e.g. increase of size, and does not mean to be the only aspect of biological evolution.

  7. Barrier screens: a method to sample blood-fed and host-seeking exophilic mosquitoes

    Directory of Open Access Journals (Sweden)

    Burkot Thomas R

    2013-02-01

    Full Text Available Abstract Background Determining the proportion of blood meals on humans by outdoor-feeding and resting mosquitoes is challenging. This is largely due to the difficulty of finding an adequate and unbiased sample of resting, engorged mosquitoes to enable the identification of host blood meal sources. This is particularly difficult in the south-west Pacific countries of Indonesia, the Solomon Islands and Papua New Guinea where thick vegetation constitutes the primary resting sites for the exophilic mosquitoes that are the primary malaria and filariasis vectors. Methods Barrier screens of shade-cloth netting attached to bamboo poles were constructed between villages and likely areas where mosquitoes might seek blood meals or rest. Flying mosquitoes, obstructed by the barrier screens, would temporarily stop and could then be captured by aspiration at hourly intervals throughout the night. Results In the three countries where this method was evaluated, blood-fed females of Anopheles farauti, Anopheles bancroftii, Anopheles longirostris, Anopheles sundaicus, Anopheles vagus, Anopheles kochi, Anopheles annularis, Anopheles tessellatus, Culex vishnui, Culex quinquefasciatus and Mansonia spp were collected while resting on the barrier screens. In addition, female Anopheles punctulatus and Armigeres spp as well as male An. farauti, Cx. vishnui, Cx. quinquefasciatus and Aedes species were similarly captured. Conclusions Building barrier screens as temporary resting sites in areas where mosquitoes were likely to fly was an extremely time-effective method for collecting an unbiased representative sample of engorged mosquitoes for determining the human blood index.

  8. Temporary deafness can impair multisensory integration: a study of cochlear-implant users.

    Science.gov (United States)

    Landry, Simon P; Guillemot, Jean-Paul; Champoux, François

    2013-07-01

    Previous investigations suggest that temporary deafness can have a dramatic impact on audiovisual speech processing. The aim of this study was to test whether temporary deafness disturbs other multisensory processes in adults. A nonspeech task involving an audiotactile illusion was administered to a group of normally hearing individuals and a group of individuals who had been temporarily auditorily deprived. Members of this latter group had their auditory detection thresholds restored to normal levels through the use of a cochlear implant. Control conditions revealed that auditory and tactile discrimination capabilities were identical in the two groups. However, whereas normally hearing individuals integrated auditory and tactile information, so that they experienced the audiotactile illusion, individuals who had been temporarily deprived did not. Given the basic nature of the task, failure to integrate multisensory information could not be explained by the use of the cochlear implant. Thus, the results suggest that normally anticipated audiotactile interactions are disturbed following temporary deafness.

  9. 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.

  10. The Impact of Education and Occupation on Temporary and Permanent Work Incapacity

    DEFF Research Database (Denmark)

    Datta Gupta, Nabanita; Lau, Daniel; Pozzoli, Dario

    This paper investigates whether education and working in a physically demand- ing job causally impact temporary work incapacity, i.e. sickness absence, and permanent work incapacity, i.e. the inflow to disability via sickness absence. Our contribution is to allow endogeneity of both education...... and occupation by estimating a quasi-maximum-likelihood discrete factor model. Data on sickness absence and disability spells for the population of older workers come from the Danish administrative registers for 1998-2002. We generally find an independent role of both education and occupation on temporary work...... incapacity only. Having at least primary education reduces women's (men's) probability of temporary work incapacity by 16% (38%) while working in a physically demanding job increases it by 37% (26%). On the other hand, conditional on sickness absence, the effects of education and occupation on permanent work...

    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

    2007-01-01

    We report the case of an infected nonunion of the proximal femoral in an elderly patient. There was extensive involvement of the entire proximal femur precluding salvage. An impromptu use of a cephalomedullary nail coated with antibiotic-laden bone cement is described, followed by reimplantation with a revision-type proximal femoral prosthesis. The patient had resection of the proximal femur, placement of a temporary functional spacer, and reimplantation after a course of antibiotics, with good success. The method we describe is a reasonable alternative when standard off-the-shelf systems or other methods of temporary spacer creation are not available.

    Concerns have been raised about nephrology fellows' skills in inserting temporary hemodialysis catheters. Less is known about temporary hemodialysis catheter insertion skills of attending nephrologists supervising these procedures. The aim of this study was to compare baseline temporary hemodialysis catheter insertion skills of attending nephrologists with the skills of nephrology fellows before and after a simulation-based mastery learning (SBML) intervention. This pre- post-intervention study with a pretest-only comparison group was conducted at the University of Toronto in September of 2014. Participants were nephrology fellows and attending nephrologists from three university-affiliated academic hospitals who underwent baseline assessment of internal jugular temporary hemodialysis catheter insertion skills using a central venous catheter simulator. Fellows subsequently completed an SBML intervention, including deliberate practice with the central venous catheter simulator. Fellows were expected to meet or exceed a minimum passing score at post-test. Fellows who did not meet the minimum passing score completed additional deliberate practice. Attending nephrologist and fellow baseline performance on the temporary hemodialysis catheter skills assessment was compared. Fellows' pre- and post-test temporary hemodialysis catheter insertion performance was compared to assess the effectiveness of SBML. The skills assessment was scored using a previously published 28-item checklist. The minimum passing score was set at 79% of checklist items correct. In total, 19 attending nephrologists and 20 nephrology fellows participated in the study. Mean attending nephrologist checklist scores (46.1%; SD=29.5%) were similar to baseline scores of fellows (41.1% items correct; SD=21.4%; P=0.55). Only two of 19 attending nephrologists (11%) met the minimum passing score at baseline. After SBML, fellows' mean post-test score improved to 91.3% (SD=6.9%; Pnephrology fellows' skills, with

    A new representation of the distribution of potential barriers present in heavy ion reactions is defined in terms of the elastic scattering excitation function. Its validity is demonstrated for the systems {sup 16}0 + {sup 144,} {sup 154}Sm, {sup 186}W, {sup 208}Pb, for which precise measurements have been made. Compared with fusion barrier distributions, which show structures characteristic of collective inelastic couplings, the elastic distributions are less detailed. This appears to be due to couplings to weaker direct reaction channels. 20 refs., 3 figs.

    2017-10-01

    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.

    2016-04-01

    Every year Canada hosts approximately 40,000 temporary foreign migrant farmworkers (MFWs). They are predominantly Mexican and Caribbean married men or single mothers who leave their families for months at a time over a span of many years. This pilot study investigated their knowledge about HIV/AIDS, attitudes towards condoms and their use, and perceived barriers to accessing sexual health services. A survey (n = 103) and four focus groups (n = 21) were conducted in Ontario's Niagara Region. The results suggest that MFWs commonly face vulnerabilities to HIV/AIDS, STIs and other sexual health issues due to personal, social-cultural, environmental and structural factors. The findings highlight the need for increasing culturally and gender sensitive sexual health education and harm reduction outreach and providing information about local health care systems and resources for MFWs. The study also calls for further community-based research and actions to reduce MFWs' perceived access barriers to health care services.

    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.

    The specific contact resistivity of Cu with ({alpha} + {beta})-Ta, TiN, {alpha}-W, and amorphous-Ta{sub 36}Si{sub 14}N{sub 50} barrier films is measured using a novel four-point-probe approach. Geometrically, the test structures consist of colinear sets of W-plugs to act as current and voltage probes that contact the bottom of a planar Cu/barrier/Cu stack. Underlying Al interconnects link the plugs to the current source and voltmeter. The center-to-center distance of the probes ranges from 3 to 200 {micro}m. Using a relation developed by Vu et al., a contact resistivity of roughly 7 {times} 10{sup {minus}9} {Omega} cm{sup 2} is obtained for all tested barrier/Cu combinations. By reflective-mode small-angle X-ray scattering, the similarity in contact resistivity among the barrier films may be related to interfacial impurities absorbed from the deposition process.

    lipid structures filling the intercellular spaces mainly control the barrier function. The barrier in cholesteatoma epithelium is several times thicker than in unaffected skin but presents distinctive features of a defective barrier as seen in other scaling skin diseases. The intercellular spaces appear...... frequently occur. The corneocytes are shed in clusters, not as single cells. Further, lipid droplets and intracellular membranous material are occasionally seen. In spite of these clear signs of barrier dysfunction, it is unknown whether the thickness of the barrier compensates for the defect in barrier...

    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.

    The presence of firearms in the home increases the risk of suicide for residents. As a result, clinicians and professional organizations recommend counseling about temporary removal of firearms from the home of potentially suicidal individuals. In some states, however, firearm laws may affect the ability to easily transfer a gun temporarily to reduce suicide risk. In particular, universal background check (UBC) laws-which require a background check whenever a gun is transferred, even by non-gun dealers-may also apply to temporary transfers intended to reduce suicide risk. Clinicians have previously reported that confusion regarding state firearm laws and uncertainty over the legality of a temporary transfer have affected their ability to effectively counsel patients. We summarize the laws of all 50 states and specifically examine the relevant firearm laws of 3 representative states with UBCs and different approaches-Maryland, Colorado, and California. We identify both helpful and problematic aspects of state laws regarding temporary transfer of firearms. We provide recommendations for amending UBC laws to make it easier for clinicians and patients to temporarily transfer firearms.

    Kanerva, L; Alanko, K; Estlander, T

    1999-12-01

    Occupational allergic contact dermatitis caused by (meth)acrylates is common in dental personnel, whereas dental acrylic fillings and crowns have rarely been reported to cause problems in dental patients. Here we report on a 48-year-old woman who developed gingivitis, stomatitis, and perioral dermatitis after a temporary crown made of restorative, two-component material had been inserted. The manufacturer stated that the temporary crown base paste and catalyst contained three (meth)acrylates, namely, a proacrylate, which is a modification of 2,2-bis[4-(2-hydroxy-3-methacryloxypropoxy)phenyl]propane (BIS-GMA); a tricyclate, which is a saturated, aliphatic, tricyclic methacrylate; and urethane methacrylate. The manufacturer refused to give more exact information on the (meth)acrylates. Patch testing revealed that the patient was highly allergic to BIS-GMA, other epoxy diacrylates, and (meth)acrylates, as well as to the base paste and catalyst of the temporary crown. Accordingly, it was concluded that the allergic reaction was caused by BIS-GMA, or a cross-reacting (meth)acrylate, or other (meth)acrylates in the temporary crown.

  14. Temporary Catheter Insertions and Complications in Our Nephrology Clinic: Clinical Experience of One Year

    Directory of Open Access Journals (Sweden)

    Özger Akarsu

    2017-06-01

    Full Text Available Aim: Urgent hemodialysis in patients with renal insufficiency is usually provided by catheter insertions. Early complications of hemodialysis catheter insertions can increase morbidity and mortality. In this study, we investigated the characteristics of patients undergoing temporary hemodialysis catheter insertion in our nephrology clinic and complications. Methods: In this study, we reviewed the records of 151 patients in whom temporary hemodialysis catheters were inserted by the nephrologists of our clinic between August 2012 and August 2013. Demographic features, catheter insertion indications, and catheter insertion sites were assessed and complications were noted. Results: A total of 151 patients (94 female and 57 male were included in the study. The average age of the patients was 58.66±16.8 years (minimum: 17, maximum: 92. No complication was observed in 112 (74.2% patients during catheter insertions. Catheter insertion was repeated in 39 (25.8% patients for various reasons. Arterial puncture occurred in 12 (7.9% of 151 patients who had catheter insertions for the first time. None of the patients required surgical intervention. Conclusion: Temporary catheter insertions are required in patients needing urgent hemodialysis. However, they bring along the risk for many complications. Early referral of patients who require hemodialysis to nephrology clinic and application of permanent vascular interventions will reduce the need for temporary catheters and complications.

    Polymerization ability of light-curing devices can affect the light-cured material hardness. The purpose of the present study was to evaluate and compare the hardness of three temporary filling materials that had been light-cured by either a light emitting diode (LED) or a halogen light-curing unit. The temporary filling materials, First Fill, Voco Clip and Bioplic, were placed in wells in a Teflon plate. The 24 specimens of each material were divided into two groups (N.=12/group) for photo-activation by either of the two light-curing units. The LED or halogen device was applied for 40s to the top surface of each specimen. A Knoop hardness test was performed on the top and bottom surface of each specimen, with five measurements per specimen. The highest hardness values for both the LED and halogen treated groups were observed for First Fill and the lowest values were for Voco Clip in top and bottom surfaces. The hardness obtained for the three materials with the halogen unit were significantly higher than the values obtained with the LED unit in both surfaces (Phardness values on the top and bottom surfaces than Voco Clip and Bioplic temporary materials. The hardness of light-cured temporary filling materials can be affected by the type of light-curing unit.

    The purpose of this study was to compare the sealing ability of the temporary restorative materials Cavit-G, Ketac Molar Easymix, and IRM with a new light-curing temporary material, Clip, using a methylene blue dye penetration test. Endodontic access preparations were prepared in 48 intact extracted human premolars. The teeth were divided into 6 groups, including positive and negative control groups. After access preparation, cotton pellets were placed in the pulp chamber so that the space remaining for the restoration was 4 mm. After thermal cycling for 500 cycles (5 degrees C-55 degrees C), the teeth were immersed in 2% methylene blue solution at neutral (pH = 7.0) in an incubator for leakage assessment. The teeth were sectioned, and the greatest depth of dye penetration was recorded. Marginal leakage was evaluated with a stereomicroscope. Positive control sections exhibited complete dye penetration, and negative controls had none. In the experimental groups, the differences in the leakage scores of the Clip and Cavit-G groups and the other 2 groups were very marked. There were no statistically significant difference in marginal leakage between Cavit-G and Clip. The new light-curing temporary material Clip seals against marginal leakage as effectively as Cavit when used as a temporary filling.

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

    Science.gov (United States)

    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.

  18. Evidence of Hydroperiod Shortening in a Preserved System of Temporary Ponds

    Directory of Open Access Journals (Sweden)

    Carola Gómez-Rodríguez

    2010-06-01

    Full Text Available Based on field data simultaneous with Landsat overpasses from six different dates, we developed a robust linear model to predict subpixel fractions of water cover. The model was applied to a time series of 174 Landsat TM and ETM+ images to reconstruct the flooding regime of a system of small temporary ponds and to study their spatio-temporal changes in a 23-year period. We tried to differentiate natural fluctuations from trends in hydrologic variables (i.e., hydroperiod shortening that may threaten the preservation of the system. Although medium-resolution remote sensing data have rarely been applied to the monitoring of small-sized wetlands, this study evidences its utility to understand the hydrology of temporary ponds at a local scale. We show that the temporary ponds in Doñana National Park constitute a large and heterogeneous system with high intra and inter-annual variability. We also evidence that the conservation value of this ecosystem is threatened by the observed tendency to shorter annual hydroperiods in recent years, probably due to aquifer exploitation. This system of temporary ponds deserves special attention for the high density and heterogeneity of natural ponds, not common in Europe. For this reason, management decisions to avoid its destruction or degradation are critical.

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

    Science.gov (United States)

    Fernandes, Daniel Jogaib; Elias, Carlos Nelson; Ruellas, Antônio Carlos de Oliveira

    2015-01-01

    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. PMID:28793582

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

    Directory of Open Access Journals (Sweden)

    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

    2017-04-01

    Each year, the French Special Weapons And Tactics team, Groupe d'Intervention de la Gendarmerie Nationale, recruits new members through a physically demanding 8-week selection process. The goal of this study is to estimate the incidence and the causes for temporary or final interruptions during this process for medical reasons. All of the candidates for the November 2015 selection process were included in this prospective study. The number and reasons for temporary or final interruptions were documented by military general practitioners. The applicants were 48 law enforcement professionals (2 women, mean age 29.4 years, range 22-35). In 14 cases, a temporary interruption was required and in five cases the selection process prematurely ended. Fifty-two per cent of the temporary interruptions were due to sprains, tendinopathies, fractures or muscle tears, 11% were due to burns, wounds or subcutaneous bruises, 16% were due to cranial trauma and 21% were due to medical causes. The high prevalence of minor traumatology that we observed is similar to the ones observed in other cohorts describing initial training for military personnel in the conventional forces. However, the presence of other pathologies in our study, such as cranial trauma or medical causes, is due to the specificity of this internship selection granting access to an elite unit.

  13. 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.

  7. Qualitative haemodynamic validation of a percutaneous temporary aortic valve: a proof of concept study.

    Science.gov (United States)

    Ho, P C

    2011-02-01

    The concept of temporary aortic valves has been suggested in the clinical settings of acute aortic regurgitation and transcatheter aortic valve replacement procedure (TAVR). In TAVR, suggestions have been made to pre-treat or remove the diseased aortic valve prior to implantation of the replacement valve. A successful temporary aortic valve must demonstrate the ability to prevent life-threatening haemodynamics of massive aortic regurgitation. A novel temporary aortic valve (TAV) design, comprised of inflatable balloon elements as a check-valve, can readily be deployed and retrieved via a catheter-system. A simple flow model is set up to test the TAV's performance in severe aortic regurgitation. With induced aortic regurgitation, placement of the TAV is found to increase the distal aortic diastolic pressure, to reduce the widened pulse pressure, to protect proximal aorta-left ventricle from diastolic pressure elevation and to reduce the aortic regurgitant volume. In conclusion, continued development of the TAV system can lead to a successful temporary aortic valve to be used in various appropriate clinical settings.

    Reddy, A.K.N.

    1991-10-01

    To promote energy-efficiency improvements, actions may be required at one or more levels -- from the lowest level of the consumer (residential, commercial, industrial, etc.) through the highest level of the global agencies. But barriers to the implementation of energy-efficiency improvements exist or can arise at all these levels. Taking up each one of these barriers in turn, the paper discusses specific measures that can contribute to overcoming the barriers. However, a one-barrier-one-measure approach must be avoided. Single barriers may in fact involve several sub-barriers. Also, combinations of measures are much more effective in overcoming barriers. In particular, combinations of measures that simultaneously overcome several barriers are most successful. The paper discusses the typology of barriers, explores their origin and suggests measures that by themselves or in combination with other measures, will overcome these barriers. Since most of the barriers dealt with can be found in the ``barriers`` literature, any originality in the paper lies in its systematic organization, synoptic view and holistic treatment of this issue. This paper is intended to initiate a comprehensive treatment of barriers, their origins and the measures that contribute to overcoming them. Hopefully, such a treatment will facilitate the implementation of energy-efficiency improvements involving a wide diversity of ever-changing energy end uses and consumer preferences.

  9. A study on setting of the fatigue limit of temporary dental implants.

    Science.gov (United States)

    Kim, M H; Cho, E J; Lee, J W; Kim, E K; Yoo, S H; Park, C W

    2017-07-01

    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.

  10. Patient advocacy: barriers and facilitators

    Directory of Open Access Journals (Sweden)

    2006-03-01

    Full Text Available Abstract Background During the two recent decades, advocacy has been a topic of much debate in the nursing profession. Although advocacy has embraced a crucial role for nurses, its extent is often limited in practice. While a variety of studies have been generated all over the world, barriers and facilitators in the patient advocacy have not been completely identified. This article presents the findings of a study exploring the barriers and facilitators influencing the role of advocacy among Iranian nurses. Method This study was conducted by grounded theory method. Participants were 24 Iranian registered nurses working in a large university hospital in Tehran, Iran. Semi-structured interviews were used for data collection. All interviews were transcribed verbatim and simultaneously Constant comparative analysis was used according to the Strauss and Corbin method. Results Through data analysis, several main themes emerged to describe the factors that hindered or facilitated patient advocacy. Nurses in this study identified powerlessness, lack of support, law, code of ethics and motivation, limited communication, physicians leading, risk of advocacy, royalty to peers, and insufficient time to interact with patients and families as barriers to advocacy. As for factors that facilitated nurses to act as a patient advocate, it was found that the nature of nurse-patient relationship, recognizing patients' needs, nurses' responsibility, physician as a colleague, and nurses' knowledge and skills could be influential in adopting the advocacy role. Conclusion Participants believed that in this context taking an advocacy role is difficult for nurses due to the barriers mentioned. Therefore, they make decisions and act as a patient's advocate in any situation concerning patient needs and status of barriers and facilitators. In most cases, they can not act at an optimal level; instead they accept only what they can do, which we called 'limited advocacy' in

    An intrusion delaying barrier includes primary and secondary physical structures and can be instrumented with multiple sensors incorporated into an electronic monitoring and alarm system. Such an instrumented intrusion delaying barrier may be used as a perimeter intrusion defense and assessment system (PIDAS). Problems with not providing effective delay to breaches by intentional intruders and/or terrorists who would otherwise evade detection are solved by attaching the secondary structures to the primary structure, and attaching at least some of the sensors to the secondary structures. By having multiple sensors of various types physically interconnected serves to enable sensors on different parts of the overall structure to respond to common disturbances and thereby provide effective corroboration that a disturbance is not merely a nuisance or false alarm. Use of a machine learning network such as a neural network exploits such corroboration.

    This study tested the hypothesis that bond strength of total- and self-etching adhesive systems to dentine is not affected by the presence of remnants from either eugenol-containing (EC) or eugenol-free (EF) temporary cements after standardized cleaning procedures. Thirty non-carious human third molars were polished flat to expose dentine surfaces. Provisional acrylic plates were fabricated and cemented either with EC, EF or no temporary cements. All specimens were incubated for 7 days in water at 37°C. The restorations were then taken out and the remnants of temporary cements were mechanically removed with a dental instrument. The dentine surfaces were cleaned with pumice and treated with either total-etching (TE) or self-etching (SE) dental adhesive systems. Atomic force microscopy was used to examine the presence of remnants of temporary cements before and after dentine cleaning procedures. Composite resin build-ups were fabricated and cemented to the bonded dentine surfaces with a resin luting cement. The specimens were then sectioned to obtain 0.9mm(2) beams for microtensile bond strength testing. Fractographic analysis was performed by optical and scanning electron microscopy. ANOVA showed lower mean microtensile bond strength in groups of specimens treated with EC temporary cement than in groups treated with either no cement or an EF cement (p<0.05). Mean microtensile bond strength was lower in groups employing the SE rather than the TE adhesive system (p<0.001). SE samples were also more likely to fail during initial processing of the samples. There was no evidence of interaction between cement and adhesive system effects on tensile strength. Fractographic analysis indicated different primary failure modes for SE and TE bonding systems, at the dentine-adhesive interface and at the resin cement-resin composite interface, respectively. The use of eugenol-containing temporary cements prior to indirect bonding restorations reduce, to a statistically similar

    Full Text Available Most of the limnological studies in India have focussed on a few taxa of large, permanent water bodies, and pond ecosystems, and related temporary water bodies are neglected.  We present here a faunal inventory, with representative photographs, for a single, small temporary pond, reporting over 125 species of strictly aquatic fauna and 25 species of associated fauna, even though we did not identify some groups such as Protozoa, Diptera and nymphs of Odonata, etc.  The identified species belong to seven taxa of vertebrates and invertebrates together. Arthropoda and Rotifera were the most species rich groups, observed with 83 and 45 representatives, respectively. Coleoptera were the most numerous in terms of species number.  Such a small water body holds some endemics as well as otherwise very rare animals and so deserves better attention.  We also highlight the potential and importance of such habitats for research and conservation.

    The purpose of this study was to investigate the accuracy of temporary fixation with laser welding for fixed partial dentures (FPDs). Five kinds of experimental FPD with different welding/soldering gaps were fabricated (0, 20, 50 microm for welding; 300 microm for soldering). Then, FPDs were temporary-fixed by laser welding or with a self-curing resin. Fixation accuracy was evaluated by the change in distance and the angular deformation between two retainers. The change in distance and the angular deformation between two retainers of the FPD without welding/soldering gap were significantly larger than the other FPDs (pimplants especially in the mesiodistal direction, and by taking into account the inevitable errors of the indirect method, it seemed reasonable to provide a welding space of approximately 20 microm.

    We investigate a time-delayed epidemic model for multi-strain diseases with temporary immunity. In the absence of cross-immunity between strains, dynamics of each individual strain exhibit emergence and annihilation of limit cycles due to a Hopf bifurcation of the endemic equilibrium, and a saddle-node bifurcation of limit cycles depending on the time delay associated with duration of temporary immunity. Effects of all-to-all and non-local coupling topologies are systematically investigated by means of numerical simulations, and they suggest that cross-immunity is able to induce a diverse range of complex dynamical behaviors and synchronization patterns, including discrete traveling waves, solitary states, and amplitude chimeras. Interestingly, chimera states are observed for narrower cross-immunity kernels, which can have profound implications for understanding the dynamics of multi-strain diseases.

    2016-01-01

    Despite the largely maternal inheritance of plastid genomes, the risk of transgene dissemination from transplastomic plants can limit the scope for field cultivation. There is a need for a cost-effective, scalable process to grow large quantities of transplastomic plant biomass for biosynthesis of biopharmaceuticals and other high-value heterologous proteins. Temporary immersion culture is a means of achieving this under fully contained conditions. This method describes the organogenesis of transplastomic Nicotiana tabacum callus in RITA(®) temporary immersion bioreactors to produce rootless leafy biomass, and subsequent total soluble protein extraction, SDS-PAGE, and Western immunoblot analysis of heterologous protein expression. This method can be used for propagation of plastid or nuclear transformants, though is especially suitable for transplastomic biomass, as organogenesis leads to greater expression and accumulation of transplastomic proteins due to increases in chloroplast number and size.

    Full Text Available This case report details a caudal unilateral traumatic elbow luxation in a 4-year-old male neutered Labrador following a road traffic trauma. This is a highly unusual injury in the dog. The pathogenesis and successful treatment by closed reduction followed by stabilisation with a temporary transarticular external skeletal fixator are discussed. The dog was assessed at 4 weeks and 6 months after surgery. Findings at 6 months after treatment demonstrated a normal gait with no pain or crepitation. A mild amount of soft tissue thickening around the elbow was noted. The range of motion of the elbow was limited to 45 degrees of flexion and 150 degrees of extension. This is the first case of a traumatic caudal luxation of the elbow in a dog described in the English veterinary literature and the first report of successful management of an elbow luxation in a dog by closed reduction and temporary transarticular fixation.

    2017-03-01

    Full Text Available The transition from the Fordist to post-Fordist techno-productive model has brought with it a noticeable labor flexibilization from which outsourcing is derived. Peripheral industry, such as the Colombian one that suffered a regression at the end of the last century, does not escape from this phenomenon. The present article seeks to establish the dynamics of fixed-term employment in the manufacturing industry, using information from the Annual Manufacturing Survey (AMS. The analysis found that the use of temporary employment  since the 1990s increased at the expense of permanent employment, until reaching 41.4% in 2013; in the Boyacá region, although it has grown rapidly since the beginning of this century, temporary employment is only about 30%. Direct contracting exceeded indirect hiring, which does not contradict the persistence of the above mentioned trend that has predominated in the most relevant occupational categories of the industrial sector.

    Full Text Available In this article, we study inventory models to determine the optimal special order and maximum saving cost of imperfective items when the supplier offers a temporary discount. The received items are not all perfect and the defectives can be screened out by the end of 100% screening process. Three models are considered according to the special order occurs at regular replenishment time, non-regular replenishment time, and screening time of economic order quantity cycle. Each model has two sub-cases to be discussed. In temporary discount problems, in general, there are integer operators in objective functions. We suggest theorems to find the closed-form solutions to these kinds of problems. Furthermore, numerical examples and sensitivity analysis are given to illustrate the results of the proposed properties and theorems.

    2004-11-01

    Textile dye allergy is frequently caused by azo dyes, which can cross-react with structurally similar compounds, including paraphenylenediamine. A case of allergic contact dermatitis to azo textile dyes, presenting principally as a sock dermatitis, is presented. The patient also gave a history of an episode of scalp dermatitis consistent with contact allergy to paraphenylenediamine in hair dye. It is proposed that paraphenylenediamine sensitization from a temporary skin tattoo may have been the primary sensitizing event for these reactions.

    2017-10-01

    Introduction The need for open abdomen in the treatment of severely ill neonates will increase in time as more complex abdominal procedures are undertaken. However, the experience of temporary closure of an open abdomen using vacuum-assisted closure (VAC) system is still relatively limited in premature and term neonates. The aim of this study is to describe and review our experience in the use of temporary VAC of the open abdomen for neonates with varying pathological processes. Materials and Methods A retrospective folder review of all neonates treated with VAC for open abdomen over the study period of 2010 to 2014 at our institution was performed. Results A total of 15 neonates were included in this study. Mean gestational age and postbirth age at VAC application were 33.6 ± 4.1 (28-40) weeks and 14 ± 10.2 (2-30) days, respectively. Mean weight at VAC application was 1,797.7 ± 730.8 (960-3,200) g. Initial diagnoses were necrotizing enterocolitis (seven), intestinal perforation (three), gastroschisis (two), congenital diaphragmatic hernia (two), and primary abdominal compartment syndrome (ACS) (one). Reasons for VAC application included confirmed ACS (2) and application to prevent ACS (13). Duration of VAC use was 4 ± 3.4 (0-13) days during which 2 ± 1.2 (1-5) applications were performed. Overall survival rate was 80% (12 of 15 patients). One patient with primary ACS died from sepsis with an open abdomen. The only potential VAC-related complication was an enterocutaneous fistula. Conclusion Temporary VAC of the open abdomen is a safe method of temporary abdominal closure to prevent ACS in high-risk postoperative conditions in neonates of any gestational age and birth weight.

    2015-01-01

    Premature loss of primary molars due to dental caries and their complications has been associated with space loss and eruptive difficulties, especially when the loss occurs early. The aim of our study was to determine the impact of premature loss of temporary upper molars upon the longitudinal axis of the first and second upper permanent molar. The study group included 64 patients 6-9 years old with premature loss of primary molars and a control group of 48 patients with intact temporary teeth. It was evaluated the angle between longitudinal axis of first and second upper permanent molars and occlusal plane. The sofware used is Easy Dent 4 Viewer®.The data were analyzed by using the Statistical Package for the Social Sciences (version 20.0; SPSS, Chicago, III). It was observed that premature loss of upper second deciduous molars modifies greater the vertical axis of the permanent molars than the premature loss of first upper primary molar. First upper primary molar loss cause an acceleration eruption of first premolar, which will produce a distal inclintion of the both permanent molars. The use of space maintainers after premature loss of the second upper temporary molar is a last solution in preventing tridimensional lesions in the dental arch and occlusion.

    Full Text Available Digitalis purpurea, is an example of cardiotonic drug. Digoxin and digitoxin are glycosides produced by this plant which are cardiac stimulants with a wide use in the treatment of heart problems. The objective of this investigation was to study the effect of temporary immersion on biomass production and the content of cardiotonic glycosides (digitoxin and digoxin, determined by Liquid Cromatography. Biomass production was favoured by increasing the frequency of immersions. The highest value of fresh weight (106.2 g and lower porcentage of hyperhydricity (27 % were obtained with immersions of 2 minutes every 4 hours. The content of digoxin was always lower than digitoxin. However, the concentration of digoxin increases with 6 and 8 immersions per day, while the accumulation of digitoxin was stable in all treatments. The aeration rates did not increase the biomasss and the concentration of digoxine was nule, nevertheless the concentration of digitoxine increased up to 111μg g.DW. The effect of temporary immersion on glycosides accumulation in shoots of Digitalis purpurea presented in this paper has not been described in the literature till now. temporary immersion Keywords: digitoxin, digoxin, secondary metabolites,

    To explore the significant referents of safety perceptions among permanent and temporary employees in order to identify the boundaries of safety climate in a heterogeneous workforce. Collection of data from semi-structured interviews with employees in manufacturing organizations, using a combination of qualitative and quantitative methods to identify basic safety perceptions. Independent raters used content analysis to examine the data. Analysis of the data revealed differences between safety themes at organization, group and individual levels. Themes relating to the individual were more prevalent among temporary employees, while those relating to the group and the organization prevailed among permanent employees. Permanent employees view organizational and group levels as significant referents of safety perceptions, while temporary employees focus on the individual level. The results challenge the current view of safety climate as a uniform concept for all employees and prescribe boundary conditions for safety climate. It is suggested that organizations should implement "tailor-made" safety-climate practices according to the referents of employee sub-groups. 2009 Elsevier Ltd. All rights reserved.

  4. Staged fracturing of horizontal shale gas wells with temporary plugging by sand filling

    Full Text Available Due to downhole complexities, shale-gas horizontal well fracturing in the Sichuan Basin suffered from casing deformation and failure to apply the technique of cable-conveyed perforation bridge plug. In view of these problems, a new technique of staged volume fracturing with temporary plugging by sand filling is employed. Based on theoretical analyses and field tests, a design of optimized parameters of coiled tubing-conveyed multi-cluster sand-blasting perforation and temporary plugging by sand filling was proposed. It was applied in the horizontal Well ZJ-1 in which casing deformation occurred. The following results are achieved in field operations. First, this technique enables selective staged fracturing in horizontal sections. Second, this technique can realize massive staged fracturing credibly without mechanical plugging, with the operating efficiency equivalent to the conventional bridge plug staged fracturing. Third, full-hole is preserved after fracturing, thus it is possible to directly conduct an open flow test without time consumption of a wiper trip. The staged volume fracturing with temporary plugging by sand filling facilitated the 14-stage fracturing in Well ZJ-1, with similar SRV to that achieved by conventional bridge plug staged fracturing and higher gas yield than neighboring wells on the same well pad. Thus, a new and effective technique is presented in multi-cluster staged volume fracturing of shale gas horizontal wells.

    Six temporary wetlands in the region of Sejenane (Mogods, NW Tunisia) were studied in order to characterize the aquatic flora and fauna and to quantify their spatio-temporal variability. Samplings of aquatic fauna, phytosociological relevés, and measurements of the physicochemical parameters of water were taken during four different field visits carried out during the four seasons of the year (November 2009-July 2010). Despite the strong anthropic pressures on them, these temporary wetlands are home to rich and diversified biodiversity, including rare and endangered species. Spatial and temporal variations affect fauna and flora differently, as temporal variability influences the fauna rather more than the plants, which are relatively more dependent on spatial factors. These results demonstrate the interest of small water bodies for maintaining biodiversity at the regional level, and thus underscore the conservation issues of Mediterranean temporary wetlands that are declining on an ongoing basis currently.

    2018-01-01

    Full Text Available Despite that there is an operating social support system for families, social workers are affected by factors that limit effectiveness of their activities in working with families whose children are taken into temporary custody. The article aims to uncover what hinders social worker to carry out effective work in providing social services for families whose children are in temporary custody. Qualitative research data shows that the research participants’ awareness of social work effectiveness is limited to its individual components. Putting together these components one can get a broad definition of effectivenessof social work though the research participants themselves donot use such a concept. The research data reveals that micro level factors influencing effectiveness of social workers’ activities working with families whose children are in temporary custody are as follows: absence of parental motivation to seek changes and unfavourable environment as well as negative community approach to social risk families. Macro level factors limiting social work effectiveness working with the families at social risk lie in the system of social services. Inadequate management of social work, limited social workers’ access to resources necessary to restore family functions; too high workload for social workers are essential factors limiting social work effectiveness.

    2017-01-01

    Post-test examination and data analysis that followed a two week long vacuum test showed that numerous self-stick thermocouples became detached from the test article. The thermocouples were reattached with thermally conductive epoxy and the test was repeated to obtain the required data. Because the thermocouple detachment resulted in significant expense and rework, it was decided to investigate the temporary attachment methods used around NASA and to perform a test to assess their efficacy. The present work describes the testing that was performed in early and mid-2017. The test article and the temporary thermocouple attachment methods tested are described. During the first test, fully half of the thermocouples detached - although the detachment showed subtly in the data for some. The second test was performed to confirm the data from the first test and to investigate the effect of test article and thermocouple grounding. The results of the testing over temperatures ranging from -150 to 200degF are detailed and preliminary recommendations are made for temporary thermocouple attachment methods.

    The CardioWest temporary total artificial heart serves as a viable bridge to orthotopic heart transplantation in patients who are experiencing end-stage refractory biventricular heart failure. This device is associated with a low, albeit still substantial, risk of thrombosis. Platelet interactions with artificial surfaces are complex and result in continuous activation of contact proteins despite therapeutic anticoagulation. We searched the medical literature (publication dates, January 1962-October 2009) in order to evaluate means of mitigating adverse events that have occurred after implantation of the CardioWest temporary total artificial heart.We conclude that the use of a multitargeted antithrombotic approach, involving anticoagulation (bivalirudin and warfarin) and antiplatelet therapy (dipyridamole and aspirin), can mitigate the procoagulative effects of mechanical circulatory assist devices, particularly those that are associated with the CardioWest temporary total artificial heart. Careful monitoring with use of a variant multisystem approach, involving efficacy tests (thrombelastography and light transmittance aggregometry), safety tests (laboratory analyses), and warfarin genomics, may maximize the therapeutic actions and minimize the bleeding risks that are associated with the multitargeted antithrombotic approach. The development and monitoring of individualized antithrombotic regimens require that informed health professionals appreciate the complexities and grasp the hazards that are associated with these therapies.

    Intramural ectopic pregnancy is a rare type of ectopic pregnancy that may lead to life-threatening hemorrhage. In the present case, a 20-year-old woman at 18.5 weeks of gestation, G1 P0 , was diagnosed with intramural ectopic pregnancy on ultrasound and magnetic resonance imaging, which showed a 14-cm × 14-cm gestational sac on the right posterior lateral side of the uterus fundus, surrounded completely by myometrium. Considering the increased risk of bleeding during surgery, transfemoral temporary aortic balloon occlusion was performed during laparotomy. The intramural ectopic gestational sac was successfully resected without life-threatening obstetric hemorrhage. This procedure could offer an alternative approach to classic uterine artery embolization in reducing intraoperative bleeding thus avoiding blood transfusion. Aortic balloon occlusion is the temporary occlusion of the aorta, therefore it does not influence future fertility. In conclusion, transfemoral temporary aortic balloon occlusion is an effective procedure in the surgical treatment of intramural ectopic pregnancy diagnosed beyond the first trimester. © 2016 Japan Society of Obstetrics and Gynecology.

    Perineal wounds in dogs present a challenge due to limited local availability of skin for closure and constant exposure to fecal contaminants. This report describes temporary rectal stenting in two dogs following severe perineal wounds. Dog 1 presented with a 4 × 4 cm full-thickness perineal slough secondary to multiple rectal perforations. A 12 mm internal diameter endotracheal tube was placed per-rectum as a temporary stent to minimize fecal contamination. The stent was removed 18 days after placement, and the perineal wound had healed at 32 days post-stent placement, when a minor rectal stricture associated with mild, intermittent tenesmus was detected. Long-term outcome was deemed good. Dog 2 presented with multiple necrotic wounds with myiasis, circumferentially surrounding the anus and extending along the tail. A 14 mm internal diameter endotracheal tube was placed per-rectum. The perineal and tail wounds were managed with surgical debridement and wet-to-dry and honey dressings prior to caudectomy and negative pressure wound therapy (NPWT). Delayed secondary wound closure and stent removal were performed on day six without complication. Long-term outcome was deemed excellent. Temporary rectal stenting may be a useful technique for fecal diversion to facilitate resolution of complex perineal injuries, including rectal perforation.

    This study was designed to investigate the fracture strength of endodontically treated teeth temporarily restored with some commonly used interim materials. Of 90 extracted maxillary premolars used in this study, 15 were left intact as the positive control. Endodontic treatment was performed on the remaining 75 teeth. The endodontically treated teeth were then randomly assigned to 5 groups (n = 15). One group was not restored and served as the negative control. In the remaining 4 experimental groups, the teeth were restored with a temporary cement: Zonalin, IRM, Coltosol, or Fuji II LC resin-modified glass ionomer (RMGI). The fracture strengths of all teeth were measured with a universal testing machine. The fracture strength of teeth restored with RMGI was significantly greater than that of other groups (P materials was significantly lower than that of intact teeth (P resistance standpoint, RMGI may be the best choice for short-term temporary restoration of endodontically treated teeth. Other types of temporary restorative material had no reinforcing effect on tooth structure.

  12. Temporary wetland restoration after rice cultivation: is soil transfer required for aquatic plant colonization?

    2013-09-01

    Full Text Available Mediterranean temporary wetlands have considerably declined in recent decades. Today, opportunities arise for the restoration of these wetlands due to land-use changes, such as the abandonment of cultivation. One critical question is whether communities, such as those observed in natural temporary wetlands, can develop alone or if active restoration should be implemented. In a series of experimental mesocosms, we transferred soil from several temporary wetlands chosen as a set of reference ecosystems. Four months after soil transfer, vegetation in transfer mesocosms was compared to that derived from spontaneous colonization (control mesocoms. Transfer mesocosms are colonized by all target hydrophyte species transferred with the soil and the resulting communities are similar to those of reference ecosystems. They also have fewer non-target species than the control mesocosms. Even though the study period was not sufficient to draw any definitive conclusion regarding the utility of forced dispersion by soil transfer, the preliminary results are promising for an application on a larger scale.

    Full Text Available Odonata diversity was assessed in 13 temporary water bodies of Coimbatore and Salem districts in Tamil Nadu. Assessment revealed the presence of 21 species of Odonata (14 species of Anisoptera and seven species of Zygoptera belonging to 17 genera under four families. Libellulidae (Anisoptera was represented by the maximum number of species and individuals. Pantala flavescens (Libellulidae was the most abundant among 21 species. Among the temporary water bodies, the maximum number of individuals as well as species was recorded from Utkulam tank (Coimbatore district. Odonata diversity was higher in Kamalapuram tanks 1 and 2 (Salem district and lower in Ukkadam tank (Coimbatore District. Diplacodes trivialis (Rambur, Orthetrum sabina (Drury and Pantala flavescens (Fabricius were identified as temporary water body specialists because of their presence in all the 13 temporary water bodies sampled.

    To examine the outcomes of vitrectomy in ocular trauma with opaque cornea. This retrospective study included 17 eyes of 16 patients who underwent vitrectomy with temporary keratoprosthesis or endoscopy at Walter Reed Army Medical Center, Washington, DC, from March 2003 to October 2010. A temporary keratoprosthesis was used in 8 eyes (47%) and endoscopy in 9 eyes (53%). Overall, the number of eyes with visual acuity of 20/200 or better improved from 0 at baseline to 5 (29%) at 6 months. The number of eyes with retinal detachment also improved from 10 (59%) at baseline to 3 (18%) at 6 months. Vitrectomy may be safely performed in ocular trauma with opaque cornea using a temporary keratoprosthesis or endoscopy with comparable outcomes. Endoscopy allows earlier diagnosis and treatment of occult pathology and requires less time and fewer procedures to implement than the temporary keratoprosthesis. Copyright 2012, SLACK Incorporated.

    1995-10-01

    Westinghouse, in conjunction with the Department of Energy and Oak Ridge National Laboratory, has embarked upon a program for the development of advanced thermal barrier coatings for industrial gas turbines. Development of thermal barrier coatings (TBC`s) for industrial gas turbines has relied heavily on the transfer of technology from the aerospace industry. Significant differences in the time/temperature/stress duty cycles exist between these two coating applications. Coating systems which perform well in aerospace applications may not been optimized to meet power generation performance requirements. This program will focus on development of TBC`s to meet the specific needs of power generation applications. The program is directed at developing a state-of-the-art coating system with a minimum coating life of 25,000 hours at service temperatures required to meet increasing operating efficiency goals. Westinghouse has assembled a team of university and industry leaders to accomplish this goal. Westinghouse will coordinate the efforts of all program participants. Chromalloy Turbine Technologies, Inc. and Sermatech International, Inc. will be responsible for bond coat and TBC deposition technology. Praxair Specialty Powders, Inc. will be responsible for the fabrication of all bond coat and ceramic powders for the program. Southwest Research Institute will head the life prediction modelling effort; they will also be involved in coordinating nondestructive evaluation (NDE) efforts. Process modelling will be provided by the University of Arizona.

    This study was conducted to explore the prevalence of medical error underreporting and associated barriers. This cross-sectional study was performed from September to December 2012. Five hospitals, affiliated with Hamadan University of Medical Sciences, in Hamedan, Iran were investigated. A self-administered questionnaire was used for data collection. Participants consisted of physicians, nurses, midwives, residents, interns, and staffs of radiology and laboratory departments. Overall, 50.26% of subjects had committed but not reported medical errors. The main reasons mentioned for underreporting were lack of effective medical error reporting system (60.0%), lack of proper reporting form (51.8%), lack of peer supporting a person who has committed an error (56.0%), and lack of personal attention to the importance of medical errors (62.9%). The rate of committing medical errors was higher in men (71.4%), age of 50-40 years (67.6%), less-experienced personnel (58.7%), educational level of MSc (87.5%), and staff of radiology department (88.9%). This study outlined the main barriers to reporting medical errors and associated factors that may be helpful for healthcare organizations in improving medical error reporting as an essential component for patient safety enhancement.

    Full Text Available We investigated the phenomenon of sustained health-supportive behaviors among long-haul commercial truck drivers, who belong to an occupational segment with extreme health disparities. With a focus on setting-level factors, this study sought to discover ways in which individuals exhibit resiliency while immersed in endemically obesogenic environments, as well as understand setting-level barriers to engaging in health-supportive behaviors. Using a transcendental phenomenological research design, 12 long-haul truck drivers who met screening criteria were selected using purposeful maximum sampling. Seven broad themes were identified: access to health resources, barriers to health behaviors, recommended alternative settings, constituents of health behavior, motivation for health behaviors, attitude toward health behaviors, and trucking culture. We suggest applying ecological theories of health behavior and settings approaches to improve driver health. We also propose the Integrative and Dynamic Healthy Commercial Driving (IDHCD paradigm, grounded in complexity science, as a new theoretical framework for improving driver health outcomes.

  2. Improving the safety net for single mothers who face serious barriers to work.

    Blank, Rebecca M

    2007-01-01

    Rebecca Blank explores a weakness of the welfare reforms of the mid-1990s--the failure of the Temporary Assistance to Needy Families program to address the plight of so-called "hard to employ" single mothers and their children. TANF has moved many women on the welfare caseload into work, but the services it provides are not intensive or flexible enough to meet the needs of women with multiple disadvantages who find it difficult to get and keep full-time employment. Blank notes that many of these women have lost welfare benefits because of their failure to find work. Increasingly, studies show that the number of single mothers who are neither working nor on welfare has grown significantly over the past ten years. Such "disconnected" women now make up 20 to 25 percent of all low-income single mothers, and reported income in these families is extremely low. Disconnected women are likely to report multiple and serious barriers to work, including low education, learning disabilities, health problems, or a history of domestic violence or substance abuse. Counting both longer-term welfare recipients and women who are neither working nor on welfare, Blank estimates that about 2.2 million women who head families are not able to find jobs or, if they do, cannot keep them. And almost 4 million children are in the care of these severely challenged single mothers. Blank proposes a Temporary and Partial Work Waiver Program to provide more effective employment assistance and other supports for these women and their children. The program she proposes would recognize that some women might be able to work only part-time or be temporarily unable to work. It would supplement their earnings while also offering referral to services that both address their own work barriers and provide help for their children. The support, however, would be temporary. Women would be regularly reassessed for their readiness to return to work or work more hours. Such a program, Blank notes, would require

  3. Temporary Losses of Highway Capacity and Impacts on Performance: Phase 2

    2004-11-10

    Traffic congestion and its impacts significantly affect the nation's economic performance and the public's quality of life. In most urban areas, travel demand routinely exceeds highway capacity during peak periods. In addition, events such as crashes, vehicle breakdowns, work zones, adverse weather, railroad crossings, large trucks loading/unloading in urban areas, and other factors such as toll collection facilities and sub-optimal signal timing cause temporary capacity losses, often worsening the conditions on already congested highway networks. The impacts of these temporary capacity losses include delay, reduced mobility, and reduced reliability of the highway system. They can also cause drivers to re-route or reschedule trips. Such information is vital to formulating sound public policies for the highway infrastructure and its operation. In response to this need, Oak Ridge National Laboratory, sponsored by the Federal Highway Administration (FHWA), made an initial attempt to provide nationwide estimates of the capacity losses and delay caused by temporary capacity-reducing events (Chin et al. 2002). This study, called the Temporary Loss of Capacity (TLC) study, estimated capacity loss and delay on freeways and principal arterials resulting from fatal and non-fatal crashes, vehicle breakdowns, and adverse weather, including snow, ice, and fog. In addition, it estimated capacity loss and delay caused by sub-optimal signal timing at intersections on principal arterials. It also included rough estimates of capacity loss and delay on Interstates due to highway construction and maintenance work zones. Capacity loss and delay were estimated for calendar year 1999, except for work zone estimates, which were estimated for May 2001 to May 2002 due to data availability limitations. Prior to the first phase of this study, which was completed in May of 2002, no nationwide estimates of temporary losses of highway capacity by type of capacity-reducing event had

    The aim of this study was to evaluate the effects of eugenol-free temporary cement's remnants on the retentive strength of full metal crowns luted via zinc phosphate and resin cement (Maxcem) to the tooth structure. Forty complete standardized Ni-Cr crowns in four groups were cemented by two types of permanent cements: zinc phosphate cement and resin cement (Maxcem). In the two groups before permanent cementation of crowns, temporary acrylic crowns were cemented by eugenol-free temporary cement. Crowns' retention was evaluated by Universal testing machine. All data were analyzed by means of one-way ANOVA test in SPSS software version 11.5 (α=0.05). There was no significant difference in groups with prior using eugenol-free temporary cement and groups with just using two permanents cement (p-value≥0.05). The application of temporary cement before permanent cementation of full metal crowns does not have any adverse effect on retention of full metal crowns, when temporary cements are removed properly.

    Viscoelastic mucus lines all mucosal surfaces of the body and forms a potential barrier to mucosal drug delivery. Mucus is mainly composed of water and mucins; high-molecular weight glycoproteins forming an entangled network. Consequently, mucus forms a steric barrier and due to its negative charge...... and hydrophobic domains, the overall hydrophilic mucus also presents an interactive barrier limiting the free diffusion of components within and through the mucus. Furthermore, mucus is a dynamic barrier due to its continuous secretion and shedding from the mucosal surfaces. Mucus is thus a highly complex gel...... barrier to drug delivery.

    2016-01-12

    The barrier experiments are a variant of the gap test; a detonation wave in a donor HE impacts a barrier and drives a shock wave into an acceptor HE. The question we ask is: What is the trade-off between the barrier material and threshold barrier thickness to prevent the acceptor from detonating. This can be viewed from the perspective of shock initiation of the acceptor subject to a complex pressure drive condition. Here we consider key factors which affect whether or not the acceptor undergoes a shock-to-detonation transition. These include the following: shock impedance matches for the donor detonation wave into the barrier and then the barrier shock into the acceptor, the pressure gradient behind the donor detonation wave, and the curvature of detonation front in the donor. Numerical simulations are used to illustrate how these factors affect the reaction in the acceptor.

    2004-07-01

    Many years' efforts within the energy labelling area have shown large saving potentials in heating and use of electricity in buildings. At the same time it has been proved that these saving potentials, even when economically advantageous, only are cashed to a limited extent. The reason to this is ascribed to barriers that meet the individual building owner who wants to start saving energy. Most barriers are known and a lot of these have been sought overcome for some time. The questions are how many barriers still exist, have new barriers arisen and the character of these barriers. On this background the objective of this survey has been to concretize and study the barriers, which are blocking reasonable energy savings. Focus has especially been on barriers for realisation of heating savings, but through a general evaluation of energy savings of barriers other forms of energy saving methods have been taken into consideration. Special interest has been directed towards houses, typically one family houses, which are affected by the Energy Labelling Scheme. The concept barriers include all kinds of barriers, also barriers that not are acknowledged as barriers by the individual house owner, or that on closer inspection turn out to be something else than actual barriers. This note suggests an alternative inertia model, in order to create an idea of the inertness characteristic of the many house owners who understand the message but fail to act on it. (BA)

    Purpose of Review Transgender persons suffer significant health disparities and may require medical intervention as part of their care. The purpose of this manuscript is to briefly review the literature characterizing barriers to health care for transgender individuals and to propose research priorities to understand mechanisms of those barriers and interventions to overcome them. Recent Findings Current research emphasizes sexual minorities’ self report of barriers, rather than using direct methods. The biggest barrier to health care reported by transgender individuals is lack of access due to lack of providers who are sufficiently knowledgeable on the topic. Other barriers include: financial barriers, discrimination, lack of cultural competence by providers, health systems barriers and socioeconomic barriers. Summary National research priorities should include rigorous determination of the capacity of the United States health care system to provide adequate care for transgender individuals. Studies should determine knowledge and biases of the medical work force across the spectrum of medical training with regard to transgender medical care; adequacy of sufficient providers for the care required, larger social structural barriers and status of a framework to pay for appropriate care. As well, studies should propose and validate potential solutions to address identified gaps. PMID:26910276

    To identify barriers to exercise in Korean colorectal cancer patients and survivors, and to analyze differences in exercise barriers by age, gender, treatment status, and physical activity level. A total of 427 colorectal cancer patients and survivors from different stages and medical status completed a self-administered questionnaire that surveyed their barriers to exercise and exercise participation. The greatest perceived exercise barriers for the sampled population as a whole were fatigue, low level of physical fitness, and poor health. Those under 60-years old reported lack of time (p=0.008), whereas those over 60 reported low level of physical fitness (p=0.014) as greater exercise barriers than their counterparts. Women reported fatigue as a greater barrier than men (pACSM guidelines, cancer-related exercise barriers were additionally reported (p<0.001), compared to those who were. Our study suggests that fatigue, low level of physical fitness, and poor health are most reported exercise barriers for Korean colorectal cancer survivors and there are differences in exercise barriers by age, sex, treatment status, and physical activity level. Therefore, support for cancer patients should be provided considering these variables to increase exercise participation.

    The test method NBI 167/02 Radon membrane: Test of airtightness can be used for determining the airtightness of a radon barrier as a system solution. The test determines the air infiltration through the radon barrier for a number of levels of air pressure differences. The airflow through versus...... of the barrier with the low air pressure, through a well-defined opening, as a modification of the test method in general. Results, obtained using the improved test method, are shown for a number of radon barriers tested....

    Full Text Available Innovation in academic libraries is not a brand new issue. Academic libraries can benefit from successful innovation, since innovation is a key contributor to gaining and sustaining competitive advantage for survival. Building on two case studies, 28 participants from leadership teams to practitioners are involved, the qualitative findings identified the specific two types of barriers that academic libraries face by applying a barriers approach to innovation, that’s, environmental and organizational barriers. Especially, seven dimensions of two types of barriers to innovation are found.

    The objective of the Advanced Turbine Systems (ATS) Program is to develop ultra-high efficient, environmentally superior, and cost competitive gas turbine systems. The operating profiles of these industrial gas turbines are long, less cyclic with fewer transients-compared with those for aircraft gas turbine engines. Therefore, creep rather than thermal fatigue, becomes primary life-limiting for hot section components. Thermal barrier coatings (TBCs) will be used to achieve the objectives of the program. TBCs allow surface temperatures to increase without compromising the structural properties of the alloy. TBCs typically consist of a ceramic insulating layer, deposited onto the substrate with an intervening metallic layer, which imparts oxidation protection to the substrate and provides a surface to which the ceramic layer can adhere.

    A common denominator of sexual reproduction in many eukaryotic species is the exposure of an egg to excess sperm to maximize the chances of reproductive success. To avoid potential harmful or deleterious consequences of supernumerary sperm fusion to a single female gamete (polyspermy), many eukaryotes, including plants, have evolved barriers preventing polyspermy. Typically, these checkpoints are implemented at different stages in the reproduction process. The virtual absence of unambiguous reports of naturally occurring egg cell polyspermy in flowering plants is likely reflecting the success of this multiphasic strategy and highlights the difficulty to trace this presumably rare event. We here focus on potential polyspermy avoidance mechanisms in plants and discuss them in light of analogous processes in animals. Copyright © 2016 The Authors. Published by Elsevier Ltd..

    Full Text Available Artificial cardiac pacing, the use of electrical stimuli to cause contraction of heart muscle, is a sophisticated therapeutic and diagnostic tool. Its rapid technologic improvement since first developed in the late 1930’s by Hyman, has made it possible not only to avoid certain cases of death due to heart block, but also to extend and improve the quality of life. Pacemaker therapy is generally used to treat heart rate or rhythm disturbances, being either tachy- or bradyarrhythmias that produce a detrimental drop in cardiac output. Of the many different types of pacemakers and electrodes currently available, ventricular demand pacing is the most commonly used.
