Uranium minerals were discovered in the Pumpkin Buttes area, Campbell and Johnson Counties, Wyo., by the U. S. Geological Survey in October 1951. From June to November 1952, an area of about 750 square miles was examined for uranium deposits, and 211 localities having abnormally high radioactivity were found; uranium minerals are visible at 121 of these localities. All known uranium mineralization in the area is restricted to sandstones of the Wasatch formation, except sparsely disseminated uranium in the sandstone of the White River formation, which caps the Pumpkin Buttes, mid several localities on the Great Pine Ridge southwest of the Pumpkin Buttes where iron-saturated sandstone and clinker in the Fort Union formation have above-normal radioactivity. The uranium occurrences in the Wasatch formation are in a red sandstone zone 450 to 900 feet above the base of the formation and are of two types: small concretionary masses of uranium, iron, manganese and vanadium minerals in sandstone, and irregular zones in which uranium minerals are disseminated in sandstone. The second type is usually larger but of lower grade than the first. Most of the localities at which uranium occurs are in a north-trending belt about 60 miles long and 18 miles in maximum width.

Regulating the disposal of cigarette butts as toxic hazardous waste.

Science.gov (United States)

Barnes, Richard L

2011-05-01

The trillions of cigarette butts generated each year throughout the world pose a significant challenge for disposal regulations, primarily because there are millions of points of disposal, along with the necessity to segregate, collect and dispose of the butts in a safe manner, and cigarette butts are toxic, hazardous waste. There are some hazardous waste laws, such as those covering used tyres and automobile batteries, in which the retailer is responsible for the proper disposal of the waste, but most post-consumer waste disposal is the responsibility of the consumer. Concepts such as extended producer responsibility (EPR) are being used for some post-consumer waste to pass the responsibility and cost for recycling or disposal to the manufacturer of the product. In total, 32 states in the US have passed EPR laws covering auto switches, batteries, carpet, cell phones, electronics, fluorescent lighting, mercury thermostats, paint and pesticide containers, and these could be models for cigarette waste legislation. A broader concept of producer stewardship includes EPR, but adds the consumer and the retailer into the regulation. The State of Maine considered a comprehensive product stewardship law in 2010 that is a much better model than EPR. By using either EPR or the Maine model, the tobacco industry will be required to cover the cost of collecting and disposing of cigarette butt waste. Additional requirements included in the Maine model are needed for consumers and businesses to complete the network that will be necessary to maximise the segregation and collection of cigarette butts to protect the environment.

Mentoring relationships, for all medical school faculty members, are an important component of lifelong development and education, yet an understanding of mentoring among medical school clinical faculty members is incomplete. This study examined associations between formal mentoring relationships and aspects of faculty members' engagement and satisfaction. It then explored the variability of these associations across subgroups of clinical faculty members to understand the status of mentoring and outcomes of mentoring relationships. The authors hypothesised that academic clinical faculty members currently in formal mentoring relationships experience enhanced employee engagement and satisfaction with their department and institution. Medical school faculty members at 26 self-selected USA institutions participated in the 2011-2014 Faculty Forward Engagement Survey. Responses from clinical faculty members were analysed for relationships between mentoring status and perceptions of engagement by faculty members. Of the 11 953 clinical faculty respondents, almost one-third reported having a formal mentoring relationship (30%; 3529). Most mentored faculty indicated the relationship was important (86%; n = 3027), and over three-fourths were satisfied with their mentoring experience (77%; n = 2722). Mentored faculty members across ranks reported significantly higher levels of satisfaction and more positive perceptions of their roles in the organisation. Faculty members who were not receiving mentoring reported significantly less satisfaction with their workplace environment and lower overall satisfaction. Mentored clinical faculty members have significantly greater satisfaction with their department and institution. This multi-institutional study provides evidence that fostering mentoring opportunities may facilitate faculty members' satisfaction and engagement, which, in turn, may help medical schools retain high-quality faculty staff committed to the multidimensional

The American Thoracic Society (ATS), in collaboration with George Mason University, surveyed a random sample of ATS members to assess their perceptions of, clinical experiences with, and preferred policy responses to climate change. An e-mail containing an invitation from the ATS President and a link to an online survey was sent to 5,500 randomly selected U.S. members; up to four reminder e-mails were sent to nonrespondents. Responses were received from members in 49 states and the District of Columbia (n = 915); the response rate was 17%. Geographic distribution of respondents mirrored that of the sample. Survey estimates' confidence intervals were ±3.5% or smaller. Results indicate that a large majority of ATS members have concluded that climate change is happening (89%), that it is driven by human activity (68%), and that it is relevant to patient care ("a great deal"/"a moderate amount") (65%). A majority of respondents indicated they were already observing health impacts of climate change among their patients, most commonly as increases in chronic disease severity from air pollution (77%), allergic symptoms from exposure to plants or mold (58%), and severe weather injuries (57%). A larger majority anticipated seeing these climate-related health impacts in the next 2 decades. Respondents indicated that physicians and physician organizations should play an active role in educating patients, the public, and policy makers on the human health effects of climate change. Overall, ATS members are observing that human health is already adversely affected by climate change and support responses to address this situation.

Botkin, J

2001-01-10

The recent controversy at Virginia Commonwealth University involving research ethics raises important and complex issues in survey and pedigree research. The primary questions are whether family members of survey respondents themselves become subjects of the project and if they are subjects whether informed consent must be obtained for investigators to retain private information on these individuals. This article provides an analysis of the ethical issues and regulatory standards involved in this debate for consideration by investigators and institutional review boards. The analysis suggests that strong protections for the rights and welfare of subjects and their family members can be incorporated into survey and pedigree research protocols without hindering projects with extensive consent requirements.

A study of fatigue life distribution of butt-welded joints

International Nuclear Information System (INIS)

Sakai, Tatsuo; Fujitani, Keizo; Kikuchi, Toshiro; Tanaka, Takao.

1981-01-01

Various kinds of welded joints are being used in many structures such as ships, bridges and constructions. It is important in reliability analysis of such structures to clarify the statistical fatigue property of the welded joints. In this study, fatigue tests were carried out on the butt-welded joints of SM50A steel and a theoretical interpretation on the fatigue life distribution was attempted, assuming that a butt-welded joint is composed of a number of sliced specimens with different fatigue strengths. Main results obtained are summarized as follows; (1) The median crack initiation life of the butt-welded joint specimens coincided with that of the sliced specimens, when the crack initiation was defined by a 0.2 mm crack in the sliced specimens or the equivalent state of stress intensity factor in the joint specimens. (2) The distribution of crack initiation lives of the butt-welded joints can be theoretically derived by combining the concept of extreme distribution and the distribution model on the number of fatigue cracks. The theoretical distribution of crack initiation lives of the joints is in good agreement with the general trend of the experimental results. (3) If the distribution of crack initiation lives and the crack growth law are given experimentally, one can obtain analytically the distribution of final fatigue lives. The fatigue life distribution of the sliced specimens can be explained by the theory established in this study. (author)

Predicting health plan member retention from satisfaction surveys: the moderating role of intention and complaint voicing.

Science.gov (United States)

Huppertz, John W

2008-01-01

Many health plans have tried to increase member retention by improving their scores on customer satisfaction surveys. However, prior research has demonstrated weak relationships between member satisfaction and retention, suggesting that other variables are needed to understand how satisfaction impacts member retention. In a longitudinal study 4,806 health plan members who completed satisfaction surveys were re-assessed three years later; we compared measures of satisfaction, intention, and complaining behavior from voluntary disenrollees and retained members. The relationship between satisfaction and retention was moderated by members' intentions to disenroll. The findings suggest that health plans can enhance the predictive validity of their satisfaction surveys by including measures of both satisfaction and intentions.

This work deals with the effects of laser beam power, focus position and advance speed on the geometry, microstructure and mechanical properties such as the tensile strength and microhardness of autogenously fibre laser beam welded Ti-6Al-2Sn-4Zr-2Mo (denoted as Ti-6242) butt joints used for high temperature applications. The Ti-6242 sheet employed here is characterized by a globular (α+β) microstructure. Laser beam welded butt joints consisted of a martensitic fusion zone, inhomogeneous heat affected zones and equiaxed base materials. The microhardness increased from 330 HV 0.3 in base material to 430 HV 0.3 in fusion zone due to the martensitic transformation. Butt joints showed the base material level of strength in tensile test. The local increase in microhardness provided a shielding effect that protected the Ti-6242 butt joint against mechanical damage during the static tensile load test. The predicted critical total underfill depth that does not reduce the tensile strength of the weld was determined to be 25% of the specimen thickness. - Highlights: • Autogenous fibre LBW of Ti-6242 was successfully achieved. • Butt joints showed low levels of porosity and an appropriate seam geometry. • Base material level of strength achieved for tensile strength. • Predicted critical underfill depth is 25% of the specimen thickness.

Cigarettes butts and the case for an environmental policy on hazardous cigarette waste.

Science.gov (United States)

Novotny, Thomas E; Lum, Kristen; Smith, Elizabeth; Wang, Vivian; Barnes, Richard

2009-05-01

Discarded cigarette butts are a form of non-biodegradable litter. Carried as runoff from streets to drains, to rivers, and ultimately to the ocean and its beaches, cigarette filters are the single most collected item in international beach cleanups each year. They are an environmental blight on streets, sidewalks, and other open areas. Rather than being a protective health device, cigarette filters are primarily a marketing tool to help sell 'safe' cigarettes. They are perceived by much of the public (especially current smokers) to reduce the health risks of smoking through technology. Filters have reduced the machine-measured yield of tar and nicotine from burning cigarettes, but there is controversy as to whether this has correspondingly reduced the disease burden of smoking to the population. Filters actually may serve to sustain smoking by making it seem less urgent for smokers to quit and easier for children to initiate smoking because of reduced irritation from early experimentation. Several options are available to reduce the environmental impact of cigarette butt waste, including developing biodegradable filters, increasing fines and penalties for littering butts, monetary deposits on filters, increasing availability of butt receptacles, and expanded public education. It may even be possible to ban the sale of filtered cigarettes altogether on the basis of their adverse environmental impact. This option may be attractive in coastal regions where beaches accumulate butt waste and where smoking indoors is increasingly prohibited. Additional research is needed on the various policy options, including behavioral research on the impact of banning the sale of filtered cigarettes altogether.

Achieving adequate response rates from family members of critically ill patients can be challenging, especially when assessing psychological symptoms. To identify factors associated with completion of surveys about psychological symptoms among family members of critically ill patients. Using data from a randomized trial of an intervention to improve communication between clinicians and families of critically ill patients, we examined patient-level and family-level predictors of the return of usable surveys at baseline, three months, and six months (n = 181, 171, and 155, respectively). Family-level predictors included baseline symptoms of psychological distress, decisional independence preference, and attachment style. We hypothesized that family with fewer symptoms of psychological distress, a preference for less decisional independence, and secure attachment style would be more likely to return questionnaires. We identified several predictors of the return of usable questionnaires. Better self-assessed family member health status was associated with a higher likelihood and stronger agreement with a support-seeking attachment style with a lower likelihood, of obtaining usable baseline surveys. At three months, family-level predictors of return of usable surveys included having usable baseline surveys, status as the patient's legal next of kin, and stronger agreement with a secure attachment style. The only predictor of receipt of surveys at six months was the presence of usable surveys at three months. We identified several predictors of the receipt of surveys assessing psychological symptoms in family of critically ill patients, including family member health status and attachment style. Using these characteristics to inform follow-up mailings and reminders may enhance response rates. Copyright © 2017 American Academy of Hospice and Palliative Medicine. Published by Elsevier Inc.

Multipass circumferential butt-welding of stainless steel pipes is simulated numerically in a non-linear thermo-mechanical FE-analysis. In particular, the through-thickness variation at the weld and heat affected zone, of the axial and hoop stresses and their sensitivity to variation in weld parameters are studied. Recommendations are given for the through thickness variation of the axial and hoop stresses to be used when assessing the growth of surface flaws at circumferential butt welds in nuclear piping system. 31 refs, 12 tabs, 54 figs.

Analysis and Prediction of the Billet Butt and Transverse Weld in the Continuous Extrusion Process of a Hollow Aluminum Profile

Science.gov (United States)

Lou, Shumei; Wang, Yongxiao; Liu, Chuanxi; Lu, Shuai; Liu, Sujun; Su, Chunjian

2017-08-01

In continuous extrusions of aluminum profiles, the thickness of the billet butt and the length of the discarded extrudate containing the transverse weld play key roles in reducing material loss and improving product quality. The formation and final distribution of the billet butt and transverse weld depend entirely on the flow behavior of the billet skin material. This study examined the flow behavior of the billet skin material as well as the formation and evolution of the billet butt and the transverse weld in detail through numerical simulation and a series of experiments. In practical extrusions, even if the billet skin is removed by lathe turning shortly before extrusion, billet skin impurities are still distributed around the transverse weld and in the billet butt. The thickness of the scrap billet butt and the length of the discarded extrudate containing the transverse weld can be exactly predicted via simulation.

Narang, H. K.; Mahapatra, M. M.; Jha, P. K.; Biswas, P.

2014-05-01

Autogenous arc welds with minimum upper weld bead depression and lower weld bead bulging are desired as such welds do not require a second welding pass for filling up the upper bead depressions (UBDs) and characterized with minimum angular distortion. The present paper describes optimization and prediction of angular distortion and weldment characteristics such as upper weld bead depression and lower weld bead bulging of TIG-welded structural steel square butt joints. Full factorial design of experiment was utilized for selecting the combinations of welding process parameter to produce the square butts. A mathematical model was developed to establish the relationship between TIG welding process parameters and responses such as upper bead width, lower bead width, UBD, lower bead height (bulging), weld cross-sectional area, and angular distortions. The optimal welding condition to minimize UBD and lower bead bulging of the TIG butt joints was identified.

1983-01-01

An attempt is made to develop a radiographic technique for examining K-type full penetration butt joints in heavy duty crane girders. The existing standard techniques of radiographic examination is found to be unsuitable to assess the internal defects properly. The examination technique reported here is successful in detecting not only the nature of the internal defects but also their degree of severities - from which clues for avoiding the most probable defects can be found out. The results of radiographic examination applied on the K-type butt joints of heavy duty crane girders have been discussed and it is specified that the acceptable limit of the defects must lie between 'blue' and 'green' according to the IIW colour code. Much work is yet to be done before standard specifications regarding the acceptibility of the defects in the actual job can be formulated. (author)

The purpose of this study was to document current practices among pediatric and general dentists who are members of the American Academy of Pediatric Dentistry (AAPD) regarding the use of local anesthesia (LA) on children undergoing dental rehabilitation under general anesthesia (GA). A survey was administered via e-mail to AAPD members to document the use of LA during dental rehabilitations under GA and the rationales for its use. A total of 952 of 5,599 members responded to this survey; 79 percent of respondents use LA at least part of the time during dental rehabilitations under GA. "Improved patient recovery" was the most commonly cited rationale for administering LA. Extraction of permanent and primary teeth were the two most common procedures cited for the use of LA, respectively. There is no consensus among the respondents on the use of local anesthesia during dental rehabilitation under general anesthesia, but the majority responded that it does play a role in their perioperative patient management.

A survey for low-mass stellar and substellar members of the Hyades open cluster

Context. Unlike young open clusters (with ages 2MASS JHKs photometry Results: We present a photometric and proper motion survey covering 23.4 deg2 in the Hyades cluster core region. Using optical/IR colour-magnitude diagrams, we identify 66 photometric cluster member candidates in the magnitude range 14.m7 < I < 20.m5. The proper motion measurements are based on several all-sky surveys with an epoch difference of 60-70 yr for the bright objects. The proper motions allowed us to discriminate the cluster members from field objects and resulted in 14 proper motion members of the Hyades. We rediscover Hy 6 as a proper motion member and classify it as a substellar object candidate (BD) based on the comparison of the observed colour-magnitude diagram with theoretical model isochrones. Conclusions: With our results, the mass function of the Hyades continues to be shallow below 0.15 M⊙ indicating that the Hyades have probably lost their lowest mass members by means of dynamical evolution. We conclude that the Hyades core represents the "VLM/BD desert" and that most of the substeller objects may have already left the volume of the cluster.

Incorporation of cigarette butts into nests reduces nest ectoparasite load in urban birds: new ingredients for an old recipe?

Birds are known to respond to nest-dwelling parasites by altering behaviours. Some bird species, for example, bring fresh plants to the nest, which contain volatile compounds that repel parasites. There is evidence that some birds living in cities incorporate cigarette butts into their nests, but the effect (if any) of this behaviour remains unclear. Butts from smoked cigarettes retain substantial amounts of nicotine and other compounds that may also act as arthropod repellents. We provide the first evidence that smoked cigarette butts may function as a parasite repellent in urban bird nests. The amount of cellulose acetate from butts in nests of two widely distributed urban birds was negatively associated with the number of nest-dwelling parasites. Moreover, when parasites were attracted to heat traps containing smoked or non-smoked cigarette butts, fewer parasites reached the former, presumably due to the presence of nicotine. Because urbanization changes the abundance and type of resources upon which birds depend, including nesting materials and plants involved in self-medication, our results are consistent with the view that urbanization imposes new challenges on birds that are dealt with using adaptations evolved elsewhere.

High-density polyethylene (HDPE) piping, which has recently been applied to safety class III piping in nuclear power plants, can be butt-joined through the thermal fusion process, which heats two fused surfaces and then subject to axial pressure. The thermal fusion process generates bead shapes on the butt fusion. The stress concentrations caused by the bead shapes may reduce the fatigue lifetime. Thus, investigating the effect of the thermal butt fusion beads on fatigue behavior is necessary. This study examined the fatigue behavior of thermal butt fusion via a tensile fatigue test under stress-controlled conditions using finite element elastic stress analysis. Based on the results, the presence of thermal butt fusion beads was confirmed to reduce the fatigue lifetime in the low-cycle fatigue region while having a negligible effect in the medium- and high-cycle fatigue regions.

In nondestructive testing the evaluation of austenitic steel welds with ultrasound is a commonly used method. But, since the wave propagation, scattering, and diffraction effects in such complicated media are hardly understood, computer simulations are very helpful to increase the knowledge of the physical phenomena in such samples. A particularly powerful numerical time domain modeling tool is the well established Elastodynamic Finite Integration Technique (EFIT). Recently, EFIT has been extended to simulate elastic waves in inhomogeneous anisotropic media. In this paper, the step-by-step evaluation of ultrasonic wave propagation in inhomogeneous anisotropic media will be described and the results will be validated against measurements. As a simplified model, a V-butt weld with perpendicular grain structure is investigated. The coincidence between the B Scans of the simulation and the measurement of an idealized V-butt weld is remarkable and even effects predicted by theory and simulation - the appearance of two coupled quasi-SV waves - can be observed. As a next step, an improved and more realistic model of the grain orientation inside the V-butt weld is introduced. This model has been implemented in the EFIT code and has been validated against measurements. For this verification, measured and simulated B-Scans for a real-life V-butt weld have been compared and a significant coincidence has been observed. Furthermore, the main pulses in the B-Scans are interpreted by analyzing the snapshot-movies of the wavefronts

Preliminary geologic map of the Sleeping Butte volcanic centers

Crowe, B.M.; Perry, F.V.

The Sleeping Butte volcanic centers comprise two, spatially separate, small-volume ( 3 ) basaltic centers. The centers were formed by mildly explosive Strombolian eruptions. The Little Black Peak cone consists of a main scoria cone, two small satellitic scoria mounds, and associated lobate lava flows that vented from sites at the base of the scoria cone. The Hidden Cone center consists of a main scoria cone that developed on the north-facing slope of Sleeping Butte. The center formed during two episodes. The first included the formation of the main scoria cone, and venting of aa lava flows from radial dikes at the northeast base of the cone. The second included eruption of scoria-fall deposits from the summit crater. The ages of the Little Black Peak and the Hidden Cone are estimated to be between 200 to 400 ka based on the whole-rock K-Ar age determinations with large analytical undertainty. This age assignment is consistent with qualitative observations of the degree of soil development and geomorphic degradation of volcanic landforms. The younger episode of the Hidden Cone is inferred to be significantly younger and probably of Late Pleistocene or Holocene age. This is based on the absence of cone slope rilling, the absence of cone-slope apron deposits, and erosional unconformity between the two episodes, the poor horizon- development of soils, and the presence of fall deposits on modern alluvial surfaces. Paleomagnetic data show that the centers record similar but not identical directions of remanent magnetization. Paleomagnetic data have not been obtained for the youngest deposits of the Hidden Cone center. Further geochronology, soils, geomorphic, and petrology studies are planned of the Sleeping Butte volcanic centers 20 refs., 3 figs

To identify differences among faculty members in various health professional training programs in perceived benefits and challenges of implementing interprofessional education (IPE). A 19-item survey using a 5-point Likert scale was administered to faculty members across different health disciplines at a west coast, multicollege university with osteopathic medicine, pharmacy, and physician assistant programs. Sixty-two of 103 surveys (60.2%) were included in the study. Faculty members generally agreed that there were benefits of IPE on patient outcomes and that implementing IPE was feasible. However, group differences existed in belief that IPE improves care efficiency (p=0.001) and promotes team-based learning (p=0.001). Program divergence was also seen in frequency of stressing importance of IPE (p=0.009), preference for more IPE opportunities (p=0.041), and support (p=0.002) within respective college for IPE. Despite consensus among faculty members from 3 disciplines that IPE is invaluable to their curricula and training of health care students, important program level differences existed that would likely need to be addressed in advance IPE initiatives.

Mazierski, P.F.; King, J.S.

1987-01-01

The emplacement history and petrochemical evolution of the volcanics associated with Pine Butte, Crater Butte, and other nearby vents are developed and described. Four major vents were identified in the study area and their associated eruptive products were mapped. All of the vents show a marked physical elongation or linear orientation coincident with the observed rift set. Planetary exploration has revealed the importance of volcanic processes in the genesis and modification of extraterrestrial surfaces. Interpretation of surface features has identified plains-type basaltic volcanism in various mare regions of the Moon and the volcanic provinces of Mars. Identification of these areas with features that appear analogous to those observed in the Pine Butte area suggests similar styles of eruption and mode of emplacement. Such terrestrial analogies serve as a method to interpret the evolution of volcanic planetary surfaces on the inner planets

The European Gaucher Alliance (EGA) was established in 1994 and constituted in 2008 as an umbrella group supporting patient organisations for Gaucher disease. Every two years, the EGA conducts a questionnaire survey of member associations to help develop its priorities and annual work programme. Results of the latest survey are presented. Between June 2012 and April 2013, the 36 members and associate members of the EGA were asked to complete a questionnaire detailing membership numbers, disease specific treatments used by patients, means of access to treatment, availability of treatment centres and home infusions, sources of support for patients with Gaucher disease, patient organisations' activities, collaborations, funding sources and any issues of concern. Questionnaires completed in 2012 were revised in January 2013 and responses analysed between July and September 2013. Thirty three members returned data on one or more questions. Findings identified inequalities in access to treatment both within and between members' countries. Three of 27 countries, for which data were available, relied totally on humanitarian aid for treatment and 6% of untreated patients in 20 countries were untreated because of funding issues, a situation many feared would worsen with deteriorating economic climates. Access to treatment and reimbursement represented 45% of members' concerns, while 35% related to access to specialist treatment centres, home infusions and doctors with expertise in Gaucher disease. Member associations' main activities centred on patient support (59% of responses) and raising awareness of Gaucher disease and patients' needs amongst the medical community, government and healthcare decision makers and the general public (34% of responses). Twenty one (78% of respondents) indicated they were the only source of help for Gaucher disease patients in their country. For many, activities were constrained by funds; two members had no external funding source. Activities

For better welding quality, accurate path teaching for actuators must be achieved before welding. Due to machining errors, assembly errors, deformations, etc., the actual groove position may be different from the predetermined path. Therefore, it is significant to recognize the actual groove position using machine vision methods and perform an accurate path teaching process. However, during the teaching process of a narrow butt joint, the existing machine vision methods may fail because of poor adaptability, low resolution, and lack of 3D information. This paper proposes a 3D path teaching method for narrow butt joint welding. This method obtains two kinds of visual information nearly at the same time, namely 2D pixel coordinates of the groove in uniform lighting condition and 3D point cloud data of the workpiece surface in cross-line laser lighting condition. The 3D position and pose between the welding torch and groove can be calculated after information fusion. The image resolution can reach 12.5 μm. Experiments are carried out at an actuator speed of 2300 mm/min and groove width of less than 0.1 mm. The results show that this method is suitable for groove recognition before narrow butt joint welding and can be applied in path teaching fields of 3D complex components.

A Demonstration System for Capturing Geothermal Energy from Mine Waters beneath Butte, Montana

Energy Technology Data Exchange (ETDEWEB)

Blackketter, Donald [Montana Tech of the Univ. of Montana, Butte, MT (United States)

2015-06-01

Executive Summary An innovative 50-ton ground-source heat pump (GSHP) system was installed to provide space heating and cooling for a 56,000 square foot (5,200 square meter) building in Butte Montana, in conjunction with its heating and chiller systems. Butte is a location with winter conditions much colder than the national average. The GSHP uses flooded mine waters at 78F (25C) as the heat source and heat sink. The heat transfer performance and efficiency of the system were analyzed using data from January through July 2014. This analysis indicated that for typical winter conditions in Butte, Montana, the GSHP could deliver about 88% of the building’s annual heating needs. Compared with a baseline natural-gas/electric system, the system demonstrated at least 69% site energy savings, 38% source energy savings, 39% carbon dioxide emissions reduction, and a savings of $17,000 per year (40%) in utility costs. Assuming a $10,000 per ton cost for installing a production system, the payback period at natural gas costs of $9.63/MMBtu and electricity costs of $0.08/kWh would be in the range of 40 to 50 years. At higher utility prices, or lower installation costs, the payback period would obviously be reduced.

Episodic Holocene eruption of the Salton Buttes rhyolites, California, from paleomagnetic, U-Th, and Ar/Ar dating

In the Salton Trough, CA, five rhyolite domes form the Salton Buttes: Mullet Island, Obsidian Butte, Rock Hill, North and South Red Hill, from oldest to youngest. Results presented here include 40Ar/39Ar anorthoclase ages, 238U-230Th zircon crystallization ages, and comparison of remanent paleomagnetic directions with the secular variation curve, which indicate that all domes are Holocene. 238U-230Th zircon crystallization ages are more precise than but within uncertainty of 40Ar/39Ar anorthoclase ages, suggesting that zircon crystallization proceeded until shortly before eruption in all cases except one. Remanent paleomagnetic directions require three eruption periods: (1) Mullet Island, (2) Obsidian Butte, and (3) Rock Hill, North Red Hill, and South Red Hill. Borehole cuttings logs document up to two shallow tephra layers. North and South Red Hills likely erupted within 100 years of each other, with a combined 238U-230Th zircon isochron age of: 2.83 ± 0.60 ka (2 sigma); paleomagnetic evidence suggests this age predates eruption by hundreds of years (1800 cal BP). Rock Hill erupted closely in time to these eruptions. The Obsidian Butte 238U-230Th isochron age (2.86 ± 0.96 ka) is nearly identical to the combined Red Hill age, but its Virtual Geomagnetic Pole position suggests a slightly older age. The age of aphyric Mullet Island dome is the least well constrained: zircon crystals are resorbed and the paleomagnetic direction is most distinct; possible Mullet Island ages include ca. 2300, 5900, 6900, and 7700 cal BP. Our results constrain the duration of Salton Buttes volcanism to between ca. 5900 and 500 years.

A Semi-analytical model for creep life prediction of butt-welded joints in cylindrical vessels

International Nuclear Information System (INIS)

Zarrabi, K.

2001-01-01

There have been many investigations on the life assessment of high temperature weldments used in cylindrical pressure vessels, pipes and tubes over the last two decades or so. But to the author's knowledge, currently, there exists no practical, economical and relatively accurate model for creep life assessment of butt-welded joints in cylindrical pressure vessels. This paper describes a semi-analytical and economical model for creep life assessment of butt-welded joints. The first stage of the development of the model is described where the model takes into account the material discontinuities at the welded joint only. The development of the model to include other factors such as geometrical stress concentrations, residual stresses, etc will be reported separately. It has been shown that the proposed model can estimate the redistributions of stresses in the weld and Haz with an error of less than 4%. It has also been shown that the proposed model can conservatively predict the creep life of a butt-welded joint with an error of less than 16%

A new method to butt weld pipes with laser at different angles

International Nuclear Information System (INIS)

Gualini, M.M.S.

1999-01-01

Laser butt welding of pipes at different angles may be cumbersome and may require very expensive tooling. The pipe size may not allow using the laser for large volume throughputs. We propose a rotary optical head composed by an adjustable focus lens system and two reflecting mirrors. The laser beam is bent at 90 deg. C. so that weld can be performed inwards outwards. The optic head design compensates the rotary backlash and vibrations, like a penta prism thus ensuring a perfect follow up of the weld track. The optic head can be inclined at 45 deg. C. to laser butt weld pipe each other at 90 deg. C. In this case the laser beam focus position is computer controlled in order to keep the focus point always on the elliptical weld profile. The paper covers theoretical and practical aspects of the proposed device. (author)

To gauge consensus regarding a proposed definition for refractory migraine proposed by Refractory Headache Special Interest Section, and where its use would be most appropriate. Headache experts have long recognized that a subgroup of headache sufferers remains refractory to treatment. Although different groups have proposed criteria to define refractory migraine, the definition remains controversial. The Refractory Headache Special Interest Section of the American Headache Society developed a definition through a consensus process, assisted by a literature review and initial membership survey. A 12-item questionnaire was distributed at the American Headache Society meeting in 2007 during a platform session and at the Refractory Headache Special Interest Section symposium. The same questionnaire was subsequently sent to all American Headache Society members via e-mail. A total of 151 responses from AHS members form the basis of this report. The survey instrument was designed using Survey Monkey. Frequencies and percentages of the survey were used to describe survey responses. American Headache Society members agreed that a definition for refractory migraine is needed (91%) that it should be added to the International Classification of Headache Disorders-2 (86%), and that refractory forms of non-migraine headache disorders should be defined (87%). Responders believed a refractory migraine definition would be of greatest value in selecting patients for clinical drug trials. The current refractory migraine definition requires a diagnosis of migraine, interference with function or quality of life despite modification of lifestyle factors, and adequate trials of acute and preventive medicines with established efficacy. The proposed criteria for the refractory migraine definition require failing 2 preventive medications to meet the threshold for failure. Although 42% of respondents agreed with the working definition of refractory migraine, 43% favored increasing the

We report on the properties of pre-main-sequence objects in the Taurus molecular clouds as observed in seven mid- and far-infrared bands with the Spitzer Space Telescope. There are 215 previously identified members of the Taurus star-forming region in our ∼44 deg 2 map; these members exhibit a range of Spitzer colors that we take to define young stars still surrounded by circumstellar dust (noting that ∼20% of the bona fide Taurus members exhibit no detectable dust excesses). We looked for new objects in the survey field with similar Spitzer properties, aided by extensive optical, X-ray, and ultraviolet imaging, and found 148 new candidate members of Taurus. We have obtained follow-up spectroscopy for about half the candidate sample, thus far confirming 34 new members, three probable new members, and 10 possible new members, an increase of 15%-20% in Taurus members. Of the objects for which we have spectroscopy, seven are now confirmed extragalactic objects, and one is a background Be star. The remaining 93 candidate objects await additional analysis and/or data to be confirmed or rejected as Taurus members. Most of the new members are Class II M stars and are located along the same cloud filaments as the previously identified Taurus members. Among non-members with Spitzer colors similar to young, dusty stars are evolved Be stars, planetary nebulae, carbon stars, galaxies, and active galactic nuclei.

This study assesses interest in international volunteer work by members of the American Pediatric Surgical Association (APSA) and attempts to identify demographics, motivations, obstacles, and institutional issues of the respondents. An online survey service was used to send a 25-question survey to all APSA members with email addresses in November 2009. An answer to all questions was not required. Written comments were encouraged. The survey was sent to 807 members of whom 316 responded, for a response rate of 39%. International work had been done previously by 48% of respondents, whereas 95% stated that they were interested or perhaps interested in doing so. Most (83%) were interested in operating with local surgeons to teach them how to perform procedures. Altruism was the chief motivation in 75% of respondents. Primary obstacles to doing international work were family obligations and lack of time, although 37% stated that a lack of information about volunteer opportunities was an issue. A significant number of respondents (48%) stated that their institution had no established international collaborations. This study suggests that there is interest in international volunteerism among many members of APSA. Understanding the issues surrounding surgical volunteerism may facilitate humanitarian involvement among pediatric surgeons. Copyright © 2011 Elsevier Inc. All rights reserved.

Vision and spectroscopic sensing for joint tracing in narrow gap laser butt welding

Science.gov (United States)

Nilsen, Morgan; Sikström, Fredrik; Christiansson, Anna-Karin; Ancona, Antonio

2017-11-01

The automated laser beam butt welding process is sensitive to positioning the laser beam with respect to the joint because a small offset may result in detrimental lack of sidewall fusion. This problem is even more pronounced in case of narrow gap butt welding, where most of the commercial automatic joint tracing systems fail to detect the exact position and size of the gap. In this work, a dual vision and spectroscopic sensing approach is proposed to trace narrow gap butt joints during laser welding. The system consists of a camera with suitable illumination and matched optical filters and a fast miniature spectrometer. An image processing algorithm of the camera recordings has been developed in order to estimate the laser spot position relative to the joint position. The spectral emissions from the laser induced plasma plume have been acquired by the spectrometer, and based on the measurements of the intensities of selected lines of the spectrum, the electron temperature signal has been calculated and correlated to variations of process conditions. The individual performances of these two systems have been experimentally investigated and evaluated offline by data from several welding experiments, where artificial abrupt as well as gradual deviations of the laser beam out of the joint were produced. Results indicate that a combination of the information provided by the vision and spectroscopic systems is beneficial for development of a hybrid sensing system for joint tracing.

Fawcett, Jacqueline

2012-04-01

Nurses have long attempted to secure a unique identity for the profession. Many scholars are now promoting an interdisciplinary framework for nursing practice. Fawcett is convinced that interdisciplinary practice poses a danger for nursing to lose its identity and that interdisciplinary practice cannot be successful if members of each discipline do not understand the conceptual models, practice, and research of their own discipline. Dr. Janie Butts and Dr. Karen Rich interviewed Dr. Jacqueline Fawcett about her views related to discipline-specific knowledge and nursing's future. The authors conclude that Fawcett's scientific foundation gives nursing the solidarity and power necessary to determine the unique internal goods of its practice.

This semiannual status report describes activities conducted by the Principal Investigator during the first half of this third year of the NASA High Resolution Microwave Survey (HRMS) Investigator Working Group (IWG). As a (HRMS) Team Member with primary interest in the Sky Survey activity, this investigator attended IWG meetings at NASA/Ames and U.C.-Santa Cruz in Apr. and Aug. 1992, and has traveled independently to NRAO/Kitt Peak, Arizona (April 1993) and Woodbury, Georgia (July 1993). During the July 1993 visit to the Georgia Tech Research Corporation/Woodbury Research Facility, an experiment was conducted to study the effects of interference from C-band (3.7 - 4.2 GHz) geostationary spacecraft on the Sky Survey operation in that band. At the first IWG meeting in April of this year, results of a SETI observation conducted at the 203 GHz positronium hyperfine resonance using the NRAO facility at Kitt Peak, AZ, were presented, as well as updates on the development of the spaceborne RFI data bases developed for the project. At the second meeting, results of the study of interference from C-band geostationary spacecraft were presented. Likewise, a presentation was made at the accompanying 1993 Bioastronomy Symposium describing the SETI observation at the positronium hyperfine resonance.

The 2006 Canadian Dermatology Association (CDA) member survey tracked the Canadian dermatology workforce. Information on use of nondermatologist extenders, impact of financial burden on practice style, and wait times was collected in the survey. To survey Canadian dermatologists for specialty-specific physician resource information including demographics, workload, and future career plans and compare it to results from the 2001 survey. In addition, to explore three other areas not covered in the previous survey: patient access to dermatologic care through wait times, the use of nondermatologist extenders, and potential impact of educational financial debt on practice styles. CDA members in 2006 were surveyed by mail. Follow-up mailings were done for nonresponders. Survey results were compared to those of the 2001 survey. Thirty-six percent (216 of 602) of Canadian dermatologists responded (70% in 2001). The national distribution was identical between surveys. The median age increased to 55 years; two-thirds of dermatologists are male. The median retirement age remained at 65 years. There was a shift from rural to urban practice locations; 78% practice in private offices. Three-fifths of dermatologists do mainly medical dermatology, a decrease between surveys. Pediatric dermatology decreased 10%, whereas surgical dermatology increased 52% between surveys. Fewer practitioners perform noninsured services, and half as many perform research or hospital consultations or teach medical students. Financial debt burden had no impact on selection of practice style. Median wait times for nonurgent consultations doubled from 5 to 10 weeks; follow-up visits increased from 4 to 5 weeks; noninsured consultations increased from 4 to 5 weeks. The national median wait time for a third available consultation appointment was 42 days (range 7-161 days). Seventeen percent of dermatologists reported using nondermatologist extenders. Training programs produce only 60% of new practitioners

The American Thoracic Society (ATS), in collaboration with George Mason University, surveyed international members of the society to assess perceptions, clinical experiences, and preferred policy responses related to global climate change. A recruitment email was sent by the ATS President in October 2015 to 5,013 international members. Subsequently, four reminder emails were sent to nonrespondents. Responses were received from 489 members in 68 countries; the response rate was 9.8%. Half of respondents reported working in countries in Asia (25%) or Europe (25%), with the remainder in South America (18%), North America (Canada and Mexico) (18%), Australia or New Zealand (9%), and Africa (6%). Survey estimate confidence intervals were ± 5% or smaller. A high percentage of international ATS survey respondents judged that climate change is happening (96%), that it is driven by human activity (70%), and that it is relevant to patient care ("a great deal"/"a moderate amount") (80%). A majority of respondents also indicated they are already observing health impacts of climate change among their patients; most commonly as increases in chronic disease severity from air pollution (88%), allergic symptoms from exposure to plants or mold (72%), and severe weather injuries (69%). An even larger majority anticipated seeing these climate-related health impacts in the next two decades. Respondents further indicated that physicians and physician organizations should play an active role in educating patients, the public, and policy makers on the human health effects of climate change. International ATS respondents, like their counterparts in the U.S., observed that human health is already adversely affected by climate change, and support responses to address this situation.

Kim, J; Jeong, K; Chung, H; Jeong, H; Ji, M; Yun, C; Lee, J

2015-01-01

This paper examines the characteristics of butt welding joint shrinkage for shipbuilding and marine structures main plate. The shrinkage strain of butt welding joint which is caused by the process of heat input and cooling, results in the difference between dimensions of the actual parent metal and the dimensions of design. This, in turn, leads to poor quality in the production of ship blocks and reworking through period of correction brings about impediment on improvement of productivity. Through experiments on butt welding joint's shrinkage strain on large structures main plate, the deformation of welding residual stress in the form of I, Y, V was obtained. In addition, the results of experiments indicate that there is limited range of shrinkage in the range of 1 ∼ 2 mm in 11t ∼ 21.5t thickness and the effect of heat transfer of weld appears to be limited within 1000 mm based on one side of seam line so there was limited impact of weight of parent metal on the shrinkage. Finally, it has been learned that Shrinkage margin needs to be applied differently based on groove phenomenon in the design phase in order to minimize shrinkage. (paper)

Metal loading in Soda Butte Creek upstream of Yellowstone National Park, Montana and Wyoming; a retrospective analysis of previous research; and quantification of metal loading, August 1999

2001-01-01

Acid drainage from historic mining activities has affected the water quality and aquatic biota of Soda Butte Creek upstream of Yellowstone National Park. Numerous investigations focusing on metals contamination have been conducted in the Soda Butte Creek basin, but interpretations of how metals contamination is currently impacting Soda Butte Creek differ greatly. A retrospective analysis of previous research on metal loading in Soda Butte Creek was completed to provide summaries of studies pertinent to metal loading in Soda Butte Creek and to identify data gaps warranting further investigation. Identification and quantification of the sources of metal loading to Soda Butte Creek was recognized as a significant data gap. The McLaren Mine tailings impoundment and mill site has long been identified as a source of metals but its contribution relative to the total metal load entering Yellowstone National Park was unknown. A tracer-injection and synoptic-sampling study was designed to determine metal loads upstream of Yellowstone National Park.A tracer-injection and synoptic-sampling study was conducted on an 8,511-meter reach of Soda Butte Creek from upstream of the McLaren Mine tailings impoundment and mill site downstream to the Yellowstone National Park boundary in August 1999. Synoptic-sampling sites were selected to divide the creek into discrete segments. A lithium bromide tracer was injected continuously into Soda Butte Creek for 24.5 hours. Downstream dilution of the tracer and current-meter measurements were used to calculate the stream discharge. Stream discharge values, combined with constituent concentrations obtained by synoptic sampling, were used to quantify constituent loading in each segment of Soda Butte Creek.Loads were calculated for dissolved calcium, silica, and sulfate, as well as for dissolved and total-recoverable iron, aluminum, and manganese. Loads were not calculated for cadmium, copper, lead, and zinc because these elements were infrequently

2010-05-01

A total of 22 family members, whose deceased loved ones had used the services of a hospice palliative care volunteer, responded to a brief survey designed to assess the importance of the different kinds of support offered to them (family members) by the volunteer, their impressions of the volunteers' personal qualities/characteristics, their general experiences with the volunteer, and their overall satisfaction with the volunteer services. The kind of support that received the highest importance rating from family members was the opportunity to take a much-needed break from the demands of caring for their loved one, closely followed by emotional support, the volunteer spending time with them, and the volunteer providing them with information. Family members rated volunteers highly on a list of qualities/characteristics that exemplify individuals who are effective in this role. In all, 85% of the family members felt that their volunteer was well trained and 95% did not feel that their or their loved one's privacy had been invaded by having a volunteer. Overall, family members were very satisfied with the volunteer support they received. Some limitations of the study are discussed.

2015-01-01

This study presents the microstructure of the aluminum A5083 butt joint surface after it has been joined by friction stir welding (FSW) process. The FSW process is a unique welding method because it will not change the chemical properties of the welded metals. In this study, MILKO 37 milling machine was modified to run FSW process on 4 mm plate of aluminum A5083 butt joint. For the experiment, variables of travel speed and tool rotational speed based on capability of machine were used to run FSW process. The concentrated heat from the tool to the aluminum plate changes the plate form from solid to plastic state. Two aluminum plates is merged to become one plate during plastic state and return to solid when concentrated heat is gradually further away. After that, the surface and cross section of the welded aluminum were investigated with a microscope by 400 x multiplication zoom. The welding defect in the FSW aluminum was identified. Then, the result was compared to the American Welding Society (AWS) FSW standard to decide whether the plate can be accepted or rejected

Stress Distribution in the Dissimilar Metal Butt Weld of Nuclear Reactor Piping due to the Simulation Technique for the Repair Welding

International Nuclear Information System (INIS)

Lee, Hweeseung; Huh, Namsu; Kim, Jinsu; Lee, Jinho

2013-01-01

During welding, the dissimilar metal butt welds of nuclear piping are typically subjected to repair welding in order to eliminate defects that are found during post-weld inspection. It has been found that the repair weld can significantly increase the tensile residual stress in the weldment, and therefore, accurate estimation of the weld residual stress due to repair weld, especially for dissimilar metal welds using Ni-based alloy 82/182 in nuclear components, is of great importance in order to assess susceptibility to primary water stress corrosion cracking. In the present study, the stress distributions of dissimilar metal butt welds in nuclear reactor piping subjected to repair weld were investigated based on detailed nonlinear finite element analyses. Particular emphasis was placed on the variation of the stress distribution in the dissimilar metal butt weld according to the finite element welding analysis sequence for the repair welding process

Full Text Available Cigarette butts (tobacco product waste (TPW are the single most collected item in environmental trash cleanups worldwide. This brief descriptive study used an online survey tool (Survey Monkey to assess knowledge, attitudes, and beliefs among individuals representing the Framework Convention Alliance (FCA about this issue. The FCA has about 350 members, including mainly non-governmental tobacco control advocacy groups that support implementation of the World Health Organization’s (WHO Framework Convention on Tobacco Control (FCTC. Although the response rate (28% was low, respondents represented countries from all six WHO regions. The majority (62% have heard the term TPW, and nearly all (99% considered TPW as an environmental harm. Most (77% indicated that the tobacco industry should be responsible for TPW mitigation, and 72% felt that smokers should also be held responsible. This baseline information may inform future international discussions by the FCTC Conference of the Parties (COP regarding environmental policies that may be addressed within FCTC obligations. Additional research is planned regarding the entire lifecycle of tobacco’s impact on the environment.

2014-01-01

The elk herd that frequents Fossil Butte National Monument, a subset of the West Green River elk population, provides visitors with seasonal opportunities to view an iconic species of the western United States. Throughout the year, these elk range across a variety of private, State, and Federal lands within close proximity to the Monument. These lands are managed differently for various uses which can create challenging wildlife-management issues and influence the herd’s seasonal movements and distribution. Research lead by the USGS investigates some of the factors associated with these seasonal changes.

2017-09-18

This study was based on a survey to investigate perceptions of hadrontherapy of the members of the Italian Association of Medical Physics (AIFM). The survey was digitally submitted to the 991 members between the end of January and the beginning of April 2016. A 19-item questionnaire was designed focusing on advantages and disadvantages of hadrontherapy, current status and possible future improvements, and need and opportunities for future investments in Italy and abroad. Information about professional qualifications, main fields of clinical involvement and specific competencies of the respondents was also collected. The survey was completed by 121 AIFM members (response rate 12.2%). In the answers collected, it was shown that medical physicists expressed interest in hadrontherapy mainly for reasons of personal interest rather than for professional needs (90% ± 2.5% vs. 52% ± 4.3% of the respondents, respectively), with a good knowledge of the related basic aspects as well as of the pros and cons of its application. However, poor knowledge of the current status of hadrontherapy was observed among the medical physicists not directly involved at a professional level, who were less than 3% of the physicists working in radiotherapy. In light of these results, the implementation of new training and education initiatives should be devised to promote a deeper and global knowledge of hadrontherapy-related issues, not only from a theoretical point of view but also in practical terms. Moreover, a close collaboration between highly specialized medical physicists employed in hadrontherapy centers and others in oncology hospitals should be -encouraged.

2017-09-01

This study examined the prevalence of perceived stress and depressive symptoms in cancer survivors and their family members compared with subjects without cancer and without family members with cancer. The subjects of this cross-sectional study were adults ≥19 years old who participated in the 2012 Korea Community Health Survey. Stress and depressive symptoms in cancer survivors and their family members were assessed and compared to symptoms in control groups by chi-square tests and multiple logistic regression analyses. Of the 6783 cancer survivors, 26.9% and 8.7% reported having stress and depressive symptoms, respectively, and 27.7% and 5.9% of family members of cancer survivors reported having stress and depressive symptoms, respectively. Cancer survivors showed higher adjusted odds ratio (aOR) for stress (aOR = 1.26, 95% confidence interval (CI) = 1.16-1.37) and depressive symptoms (aOR = 1.82, 95% CI = 1.57-2.11) than subjects without cancer history. Family members of cancer survivors showed a higher OR for stress and depressive symptoms than subjects without a family member who survived cancer. Cancer survivors and family members of cancer survivors had more stress and depressive symptoms than controls. Careful management for cancer patients and their family members should include screening for stress and depression to improve mental health associated with cancer survivorship.

Use of pulsed arc welding for butt joint fabrication

International Nuclear Information System (INIS)

Merkulov, B.A.

1977-01-01

A technology of pulsed-arc butt welding with periodic wire feed to the welding zone has been developed. The pulsed arc is suitable both for submerged and gas-shielded weldings. The technology proposed has some advantages over the stationary-arc welding. Control of the amplitude-frequency characteristics of the process enables one to affect melting and crystallization conditions of the welding crater, weld shape, relation between melting and deposited metal section areas, etc., as well as to reduce heat contribution to the base metal. The new process is shown to be applicable in power engineering. Automatic submerged welding conditions are given for low-carbon and pearlitic heat-resistant steels

Effect of the weld groove shape and pass number on residual stresses in butt-welded pipes

International Nuclear Information System (INIS)

Sattari-Far, I.; Farahani, M.R.

2009-01-01

This study used finite element techniques to analyze the thermo-mechanical behaviour and residual stresses in butt-welded pipes. The residual stresses were also measured in some welds by using the Hole-Drilling method. The results of the finite element analysis were compared with experimentally measured data to evaluate the accuracy of the finite element modelling. Based on this study, a finite element modelling procedure with reasonable accuracy was developed. The developed FE modelling was used to study the effects of weld groove shape and weld pass number on welding residual stresses in butt-welded pipes. The hoop and axial residual stresses in pipe joints of 6 and 10 mm thickness of different groove shapes and pass number were studied. It is shown that these two parameters may have significant effects on magnitude and distribution of residual stresses in welded pipes.

Wrought stainless steel butt-welding fittings: including reference to other corrosion resistant materials - approved 1971

International Nuclear Information System (INIS)

Anon.

1975-01-01

ANSI B16.9 is the American Standard for steel butt-welding fittings and although not so stated, it is implied that its scope deals primarily with the schedules of wall thicknesses which are common to carbon steel and the grades of alloy steel piping that are selected for pressure and temperature considerations. The purpose of this standard is to provide industry with a set of dimensional standards for butt-welding fittings that can be used with these light wall pipes of corrosion resisting materials. The center-to-end dimensions of all fittings are identical with those in ANSI B16.9 which give to industry the advantage of uniform design room practice and a maximum utilization of existing die equipment. The only departure from this is in the lap-joint stub end where for purposes of economy the face-to-end of the product has been reduced for use with thin wall piping

Quality improvement and cost containment initiatives in health care increasingly involve interdisciplinary teams of providers. To understand organizational functioning, information is often needed from multiple members of a leadership team since no one person may have sufficient knowledge of all aspects of the organization. To minimize survey burden, it is ideal to ask unique questions of each member of the leadership team in areas of their expertise. However, this risks substantial missing data if all eligible members of the organization do not respond to the survey. Nursing home administrators (NHA) and directors of nursing (DoN) play important roles in the leadership of long-term care facilities. Surveys were administered to NHAs and DoNs from a random, nationally representative sample of U.S. nursing homes about the impact of state policies, market forces, and organizational factors that impact provider performance and residents' outcomes. Responses were obtained from a total of 2,686 facilities (response rate [RR] = 66.6%) in which at least one individual completed the questionnaire and 1,693 facilities (RR = 42.0%) in which both providers participated. No evidence of nonresponse bias was detected. A high-quality representative sample of two providers in a long-term care facility can be obtained. It is possible to optimize data collection by obtaining unique information about the organization from each provider while minimizing the number of items asked of each individual. However, sufficient resources must be available for follow-up to nonresponders with particular attention paid to lower resourced, lower quality facilities caring for higher acuity residents in highly competitive nursing home markets. © The Author(s) 2014.

The need to regulate physician-assisted suicide (PAS) and organizations offering assisted suicide has been controversially debated in Germany. Before the German parliament voted on various drafts in November 2015, the German Association for Palliative Medicine surveyed its members on their attitudes and experiences regarding PAS. Items for the survey were derived from the literature and consented in a focus group. 2005-2015 - PubMed: PAS [Title/Abstract] UND survey (all countries), grey literature. We invited 5152 members of the DGP to participate in the online/paper survey. Descriptive quantitative and content analytic qualitative analysis of data using SPSS and MaxQDA. We obtained 1811 valid data sets (response rate 36.9%). 33.7% of the participants were male, 43.6% were female, and 0.4% identifed as other. Physicians accounted for 48.5% of the respondents, 17.8% nurses, other professions 14.3%, and about 20% of the data was missing socio-demographic information. More than 90% agreed that "wishes for PAS may be ambivalent" and "are rather a wish to end an unbearable situation". Of the 833 participating physicians, 56% refused participating in PAS and 74.2% had been asked to perform PAS. PAS was actually performed by 3%. Of all participating members, 56% approved of a legal ban of organizations offering assisted suicide. More than 60% of all professions agreed that PAS is not a part of palliative care. The respondents show a broad spectrum of attitudes, only partly supporting statements of relevant bodies, such as DGP. Because many are confronted with the issue, PAS is relevant to professionals in palliative care.

A Precise Visual Method for Narrow Butt Detection in Specular Reflection Workpiece Welding

Directory of Open Access Journals (Sweden)

Jinle Zeng

2016-09-01

Full Text Available During the complex path workpiece welding, it is important to keep the welding torch aligned with the groove center using a visual seam detection method, so that the deviation between the torch and the groove can be corrected automatically. However, when detecting the narrow butt of a specular reflection workpiece, the existing methods may fail because of the extremely small groove width and the poor imaging quality. This paper proposes a novel detection method to solve these issues. We design a uniform surface light source to get high signal-to-noise ratio images against the specular reflection effect, and a double-line laser light source is used to obtain the workpiece surface equation relative to the torch. Two light sources are switched on alternately and the camera is synchronized to capture images when each light is on; then the position and pose between the torch and the groove can be obtained nearly at the same time. Experimental results show that our method can detect the groove effectively and efficiently during the welding process. The image resolution is 12.5 μm and the processing time is less than 10 ms per frame. This indicates our method can be applied to real-time narrow butt detection during high-speed welding process.

Special metallurgy - the electrical butt-welding by flashing of sintered magnesium-magnesium oxide composites (1963)

International Nuclear Information System (INIS)

Charleux, J.

1963-01-01

Electrical resistance welding has become quite important since World War II because of the need of a high yield in aeronautical production. Progress has been due in particular to the improvements made in electronically controlled apparatus making possible the automatic control of welding. For the butt-welding of sections requiring either a high production rate or a high quality weld, the flash butt-welding system has been very much developed these last few years. The use of this welding method is of great importance in the field of the bonding of oxidisable metals such as magnesium or aluminium and its alloys, because the welded joint is free from oxides. This study consists of general considerations on the flash-welding process with regard to temperature distribution in the parts during welding, and to electrical phenomena connected with flashing. Besides this general or theoretical section, we have applied the welding process to the bonding of sintered magnesium, a magnesium-magnesium oxide composite, whose use as a structural element in nuclear reactors is considered.

Assessment of NDE Methods on Inspection of HDPE Butt Fusion Piping Joints for Lack of Fusion with Validation from Mechanical Testing

International Nuclear Information System (INIS)

2010-01-01

Studies at the Pacific Northwest National Laboratory (PNNL) in Richland, Washington, are being conducted to evaluate nondestructive examinations (NDE) coupled with mechanical testing of butt fusion joints in high-density polyethylene (HDPE) pipe for assessing lack of fusion. The work provides information to the U.S. Nuclear Regulatory Commission (NRC) on the effectiveness of volumetric inspection techniques of HDPE butt fusion joints in Section III, Division 1, Class 3, buried piping systems in nuclear power plants. This paper describes results from preliminary assessments using ultrasonic and microwave nondestructive techniques and mechanical testing with the high-speed tensile impact test and the side-bend test for determining joint integrity. A series of butt joints were fabricated in 3408, 12-in. IPS DR-11 HDPE material by varying the fusion parameters to create good joints and joints containing a range of lack-of-fusion conditions. Six of these butt joints were volumetrically examined with time-of-flight diffraction (TOFD), phased-array (PA) ultrasound, and the Evisive microwave system. The outer-diameter weld beads were removed for the microwave inspection. In two of the four pipes, both the outer and inner weld beads were removed and the pipe joints re-evaluated. The pipes were sectioned and the joints destructively evaluated with the side-bend test by cutting portions of the fusion joint into slices that were planed and bent. The last step in this limited study will be to correlate the fusion parameters, nondestructive, and destructive evaluation results to validate the effectiveness of what each NDE technology detects and what each does not detect. The results of the correlation will be used in identifying any future work that is needed.

In-process monitoring and adaptive control for gap in micro butt welding with pulsed YAG laser

International Nuclear Information System (INIS)

Kawahito, Yousuke; Kito, Masayuki; Katayama, Seiji

2007-01-01

A gap is one of the most important issues to be solved in laser welding of a micro butt joint, because the gap results in welding defects such as underfilling or a non-bonded joint. In-process monitoring and adaptive control has been expected as one of the useful procedures for the stable production of sound laser welds without defects. The objective of this research is to evaluate the availability of in-process monitoring and adaptive control in micro butt welding of pure titanium rods with a pulsed neodymium : yttrium aluminium garnet (Nd : YAG) laser beam of a 150 μm spot diameter. It was revealed that a 45 μm narrow gap was detected by the remarkable jump in a reflected light intensity due to the formation of the molten pool which could bridge the gap. Heat radiation signal levels increased in proportion to the sizes of molten pools or penetration depths for the respective laser powers. As for adaptive control, the laser peak power was controlled on the basis of the reflected light or the heat radiation signals to stably produce a sound deeply penetrated weld reduced underfilling. In the case of a 100 μm gap, the underfilling was greatly reduced by half smaller than those made with a conventional rectangular pulse shape in seam welding as well as spot welding with a pulsed Nd : YAG laser beam. Consequently, the adaptive control of the laser peak power on the basis of in-process monitoring could reduce the harmful effects due to a gap in micro butt laser welding with a pulsed laser beam

Noble Gas Isotope Evidence for Mantle Volatiles in the Cu-Mo Porphyry and Main Stage Polymetallic Veins at Butte, Montana

Hofstra, A. H.; Rusk, B. G.; Manning, A. H.; Hunt, A. G.; Landis, G. P.

2017-12-01

Recent studies suggest that volatiles released from mafic intrusions may be important sources of heat, sulfur, and metals in porphyry Cu-Mo-Au and epithermal Au-Ag deposits associated with intermediate to silicic stocks. The huge Cu-Mo porphyry and Main Stage polymetallic vein deposits at Butte are well suited to test this hypothesis because there is no geologic or isotopic evidence of basaltic intrusions in the mine or drill holes. The Butte porphyry-vein system is associated with quartz monzonite stocks and dikes within the southwest part of the Late Cretaceous Boulder batholith. The Boulder batholith was emplaced into Mesoproterozoic to Mesozoic sedimentary rocks and Late Cretaceous volcanic rocks. The Boulder batholith and Butte intrusions have Sri and eNd values indicative of crustal contamination. Eu and Ce anomalies in zircon from Butte intrusions provide evidence of oxidation due to magma degassing. To ascertain the source of volatiles in this system, 11 samples from the Cu-Mo porphyry and 16 from Main Stage veins were selected. The isotopic composition of Ar, Ne, and He extracted from fluid inclusions in quartz, magnetite, pyrite, chalcopyrite, sphalerite, galena, enargite, and covellite were determined. Helium isotopes exceed blank levels in all samples and Ne and Ar in some samples. On a 38Ar/36Ar vs. 40Ar/36Ar diagram, data plot near air. On a 20Ne/22Ne vs. 21Ne/22Ne diagram, data extend from air along the trajectories of OIB and MORB. On a 36Ar/4He vs. 3He/4He RA diagram, data extend from crust toward the air-mantle mixing line. The maximum 3He/4He RA values in the Cu-Mo porphyry (2.86) and Main Stage veins (3.46) are from pyrite and these values correspond to 36 and 43 % mantle helium. The Ne and He results show that fluid inclusions contain volatiles discharged from mantle magmas and that these volatiles were diluted by groundwater containing He derived from country rocks. Despite the lack of mafic intrusions in the Butte magmatic center, noble gas

Reich, Shani S; Null, Robert C; Timoney, Peter J; Sokol, Jason A

To assess current members of the American Society of Ophthalmic Plastic and Reconstructive Surgery (ASOPRS) regarding preference in surgical techniques for orbital decompression in Graves' disease. A 10-question web-based, anonymous survey was distributed to oculoplastic surgeons utilizing the ASOPRS listserv. The questions addressed the number of years of experience performing orbital decompression surgery, preferred surgical techniques, and whether orbital decompression was performed in collaboration with an ENT surgeon. Ninety ASOPRS members participated in the study. Most that completed the survey have performed orbital decompression surgery for >15 years. The majority of responders preferred a combined approach of floor and medial wall decompression or balanced lateral and medial wall decompression; only a minority selected a technique limited to 1 wall. Those surgeons who perform fat decompression were more likely to operate in collaboration with ENT. Most surgeons rarely remove the orbital strut, citing risk of worsening diplopia or orbital dystopia except in cases of optic nerve compression or severe proptosis. The most common reason given for performing orbital decompression was exposure keratopathy. The majority of surgeons perform the surgery without ENT involvement, and number of years of experience did not correlate significantly with collaboration with ENT. The majority of surveyed ASOPRS surgeons prefer a combined wall approach over single wall approach to initial orbital decompression. Despite the technological advances made in the field of modern endoscopic surgery, no single approach has been adopted by the ASOPRS community as the gold standard.

Um, Tae-Hwan; Lee, Chin-Hyung; Chang, Kyong-Ho; Nguyen Van Do, Vuong

2018-04-01

Duplex stainless steel finds increasing use as an alternative to austenitic stainless steel, particularly where chloride or sulphide stress corrosion cracking is of primary concern, due to the excellent combination of strength and corrosion resistance. During welding, duplex stainless steel does not create the same magnitude or distribution of weld-induced residual stresses as those in welded austenitic stainless steel due to the different physical and mechanical properties between them. In this work, an experimental study on the residual stresses in butt-welded duplex stainless steel is performed utilizing the layering technique to investigate the characteristics of residual stresses in the weldment. Three-dimensional thermos-mechanical-metallurgical finite element analysis is also performed to confirm the residual stress measurements.

Innovative deceased donor intervention strategies have the potential to increase the number and quality of transplantable organs. Yet there is confusion over regulatory and legal requirements, as well as ethical considerations. We surveyed transplant surgeons (n = 294), organ procurement organization (OPO) professionals (n = 83), and institutional review board (IRB) members (n = 317) and found wide variations in their perceptions about research classification, risk assessment for donors and organ transplant recipients, regulatory oversight requirements, and informed consent in the context of deceased donor intervention research. For instance, when presented with different research scenarios, IRB members were more likely than transplant surgeons and OPO professionals to feel that study review and oversight were necessary by the IRBs at the investigator, donor, and transplant center hospitals. Survey findings underscore the need to clarify ethical, legal, and regulatory requirements and their application to deceased donor intervention research to accelerate the pace of scientific discovery and facilitate more transplants. © Copyright 2015 The American Society of Transplantation and the American Society of Transplant Surgeons.

Analytical model of stress field in submerged arc welding butt joint with thorough penetration

Directory of Open Access Journals (Sweden)

Winczek Jerzy

2018-01-01

Full Text Available Analytical model of temporary and residual stresses for butt welding with thorough penetration was described assuming planar section hypothesis and using integral equations of stress equilibrium of the bar and simple Hooke’s law. In solution the effect of phase transformations (structure changes and structural strains has been taken into account. Phase transformations during heating are limited by temperature values at the beginning and at the end of austenitic transformation, depending on chemical composition of steel while the progress of phase transformations during cooling is determined on the basis of TTT-welding diagram. Temperature values at the beginning and at the end of transformation are conditioned by the speed of heating. Kinetics of diffusional transformation is described basing on Johnson-Mehl-Avrami-Kolmogorov equation, while martensitic transformation, basing on Koistinen-Marburger equation. Stresses in elasto-plastic state are determined by iteration, using elastic solutions method with changeable longitudinal modulus of elasticity, conditioned by stress-strain curve. Computations of stress field have been conducted for one-side butt welded of two steel flats made from S235 steel. It has enabled a clear interpretation of influence of temperature field and phase transformation on stresses caused by welding using Submerged Arc Welding (SAW method.

A novel weld seam detection method for space weld seam of narrow butt joint in laser welding

Science.gov (United States)

Shao, Wen Jun; Huang, Yu; Zhang, Yong

2018-02-01

Structured light measurement is widely used for weld seam detection owing to its high measurement precision and robust. However, there is nearly no geometrical deformation of the stripe projected onto weld face, whose seam width is less than 0.1 mm and without misalignment. So, it's very difficult to ensure an exact retrieval of the seam feature. This issue is raised as laser welding for butt joint of thin metal plate is widely applied. Moreover, measurement for the seam width, seam center and the normal vector of the weld face at the same time during welding process is of great importance to the welding quality but rarely reported. Consequently, a seam measurement method based on vision sensor for space weld seam of narrow butt joint is proposed in this article. Three laser stripes with different wave length are project on the weldment, in which two red laser stripes are designed and used to measure the three dimensional profile of the weld face by the principle of optical triangulation, and the third green laser stripe is used as light source to measure the edge and the centerline of the seam by the principle of passive vision sensor. The corresponding image process algorithm is proposed to extract the centerline of the red laser stripes as well as the seam feature. All these three laser stripes are captured and processed in a single image so that the three dimensional position of the space weld seam can be obtained simultaneously. Finally, the result of experiment reveals that the proposed method can meet the precision demand of space narrow butt joint.

Monogenetic volcanoes fed by interconnected dikes and sills in the Hopi Buttes volcanic field, Navajo Nation, USA

Muirhead, James D.; Van Eaton, Alexa R.; Re, Giuseppe; White, James D. L.; Ort, Michael H.

2016-01-01

Although monogenetic volcanic fields pose hazards to major cities worldwide, their shallow magma feeders (networks. Analysis of vent alignments using the pyroclastic massifs and other eruptive centers (e.g., maar-diatremes) shows a NW-SE trend, parallel to that of dikes in the region. We therefore infer that dikes fed many of the eruptions. Dikes are also observed in places transforming to transgressive (ramping) sills. Estimates of the observable volume of dikes (maximum volume of 1.90 × 106 m3) and sills (minimum volume of 8.47 × 105 m3) in this study reveal that sills at Hopi Buttes make up at least 30 % of the shallow intruded volume (∼2.75 × 106 m3 total) within 350 m of the paeosurface. We have also identified saucer-shaped sills, which are not traditionally associated with monogenetic volcanic fields. Our study demonstrates that shallow feeders in monogenetic fields can form geometrically complex networks, particularly those intruding poorly consolidated sedimentary rocks. We conclude that the Hopi Buttes eruptions were primarily fed by NW-SE-striking dikes. However, saucer-shaped sills also played an important role in modulating eruptions by transporting magma toward and away from eruptive conduits. Sill development could have been accompanied by surface uplifts on the order of decimeters. We infer that the characteristic feeder systems described here for the Hopi Buttes may underlie monogenetic fields elsewhere, particularly where magma intersects shallow, and often weak, sedimentary rocks. Results from this study support growing evidence of the important role of shallow sills in active monogenetic fields.

Control of Precambrian basement deformation zones on emplacement of the Laramide Boulder batholith and Butte mining district, Montana, United States

Berger, Byron R.; Hildenbrand, Thomas G.; O'Neill, J. Michael

2011-01-01

What are the roles of deep Precambrian basement deformation zones in the localization of subsequent shallow-crustal deformation zones and magmas? The Paleoproterozoic Great Falls tectonic zone and its included Boulder batholith (Montana, United States) provide an opportunity to examine the importance of inherited deformation fabrics in batholith emplacement and the localization of magmatic-hydrothermal mineral deposits. Northeast-trending deformation fabrics predominate in the Great Falls tectonic zone, which formed during the suturing of Paleoproterozoic and Archean cratonic masses approximately 1,800 mega-annum (Ma). Subsequent Mesoproterozoic to Neoproterozoic deformation fabrics trend northwest. Following Paleozoic through Early Cretaceous sedimentation, a Late Cretaceous fold-and-thrust belt with associated strike-slip faulting developed across the region, wherein some Proterozoic faults localized thrust faulting, while others were reactivated as strike-slip faults. The 81- to 76-Ma Boulder batholith was emplaced along the reactivated central Paleoproterozoic suture in the Great Falls tectonic zone. Early-stage Boulder batholith plutons were emplaced concurrent with east-directed thrust faulting and localized primarily by northwest-trending strike-slip and related faults. The late-stage Butte Quartz Monzonite pluton was localized in a northeast-trending pull-apart structure that formed behind the active thrust front and is axially symmetric across the underlying northeast-striking Paleoproterozoic fault zone, interpreted as a crustal suture. The modeling of potential-field geophysical data indicates that pull-apart?stage magmas fed into the structure through two funnel-shaped zones beneath the batholith. Renewed magmatic activity in the southern feeder from 66 to 64 Ma led to the formation of two small porphyry-style copper-molybdenum deposits and ensuing world-class polymetallic copper- and silver-bearing veins in the Butte mining district.

2016-05-15

The long term-durability and the soundness of the plastic pipe have been sufficiently verified through use of the plastic pipe during the past several decades. Recently, as the pipe material have been constantly developed, the application of the plastic pipe is expanded to various industrial fields, such as an increase of a use pressure, the bigger diameter of the pipe, etc. In a nuclear power plant where a carbon steel pipe and a stainless steel pipe are mainly used as a safety class III buried pipe, safety in an operation is seriously threatened by abrasion, heat deterioration or the like, frequently generated in a metal pipe. Therefore, in order to provide an alternate to this problem there is a rising interest on using high-density polyethylene (HDPE) pipes which are known to provide much enhanced corrosion, abrasion and impact resistant properties. With polyethylene piping, one of the issue that is being looked into is the integrity of butt-fusion joint. At the present time the Referencing Code and Standard for the NDT technology of for butt fusion joint of the plastic pipe have not yet established. An optimum inspection parameters were determined according to the thickness of the HDPE pipe. It was also confirmed that most of the detection results of two techniques have matched with each other. In the PAUT, it is easy to distinguish signals with from the flaws made by the thin plate and the void. Also the resolving power of PAUT on the detection in the depth direction has been demonstrated to be satisfactory.

Of 429 Central Association of Obstetricians and Gynecologists members, 268 (62%) responded, with 192 (78%) filling out the survey online. Nearly 90% of those queried believed that shoulder dystocia was unpredictable and unpreventable. Thirty-seven percent felt that an elective cesarean delivery should be offered for an estimated fetal weight of 4,500 g among nondiabetics. Just 40% would have allowed a trial of labor with a documented history of shoulder dystocia. Slightly more than half answered that they never used either lateral or excessive traction and obstetrician-gynecologists were more likely than maternal-fetal medicine specialists to conclude that traction applied by the clinician doing the delivery was the cause of shoulder dystocia-related brachial plexus palsy (36% compared with 12%, P=.005). Maternal-fetal medicine specialists were more likely to believe that 40-50% of brachial plexus palsies occur without concomitant shoulder dystocia (21% compared with 9%, P=.015). Differences in practice patterns exist among with regard to management recommendations of the American College of Obstetricians and Gynecologists' Practice Bulletin on shoulder dystocia. III.

As part of a major research programme to investigate the influence of butt welds on the life expectancy of tubular components, a series of internal-pressure, stress-rupture tests have been carried out. Thick walled 1/2Cr 1/2Mo 1/4V tube specimens were welded with mild steel, 1Cr 1/2Mo steel, 2 1/4Cr 1Mo steel or nominally matching 1/2Cr 1/2Mo 1/4V steel to give a wide range of weld metal creep strengths relative to the parent tube. The weldments were tested at 565 0 C at two values of internal pressure, and gave failure lives of up to 44,000 hrs. Finite element techniques have been used to determine the stationary state stress distribution in the weldment which was represented by a three material model. Significant stress redistribution was indicated and these results enabled the position and orientation of cracking and the rupture life to be predicted. The theoretical and experimental results have been used to highlight the limitations of current design methods which are based on the application of the mean diameter hoop stress to the parent material stress rupture data.

The purpose of this survey was to assess the opinions of members of the German Society of Gynecologic Endoscopy (AGE) regarding the laparoscopic treatment of ovarian malignancies and current practice at their institutions. Between February and October 2015, the AGE sent an anonymous online survey via mail to its members. The questionnaire solicited participants' opinions about the laparoscopic treatment of ovarian cancers according to T stage and borderline tumors, and information about current practice at their institutions. Participants were also asked their opinions on currently available data on this issue. Of 228 AGE members who completed the survey, 132 (58%) were fellows or attending physicians and 156 (68%) worked at university hospitals or tertiary referral centers. Most [212 (93%)] respondents stated that < 10% of all ovarian cancer cases were currently treated laparoscopically at their institutions. Most participants indicated that T1 (a, b, c) tumors [145 (64%)] and ovarian borderline tumors [206 (90%)], but not T2 [48 (21%)] or T3/4 [9 (4%) ovarian tumors] should or could be treated laparoscopically. One hundred seventy-two (75%) participants considered currently available data on this topic to be insufficient and 152 (66%) stated that they would take part in a clinical trial assessing a laparoscopic approach to T1/2 ovarian cancer. According to this survey, to the opinion of the majority of AGE members, laparoscopy might be a considerable option for the treatment of early ovarian malignancies and borderline tumors and should be evaluated further in future studies.

Research highlights: → Friction stir weld-defect forming mechanisms of thick butt-joints. → Relationship between weld-defects and friction stir welding process parameters. → Multiple non-destructive testing methods applied to friction stir welds. → Empirical criterion basing on mass-conservation for inner material-loss defects. → Nonlinear correlation between weld strengths and root-flaw lengths. -- Abstract: The present study focused on the relationship between primary friction stir welding process parameters and varied types of weld-defect discovered in aluminum 2219-T6 friction stir butt-welds of thick plates, meanwhile, the weld-defect forming mechanisms were investigated. Besides a series of optical metallographic examinations for friction stir butt welds, multiple non-destructive testing methods including X-ray detection, ultrasonic C-scan testing, ultrasonic phased array inspection and fluorescent penetrating fluid inspection were successfully used aiming to examine the shapes and existence locations of different weld-defects. In addition, precipitated Al 2 Cu phase coarsening particles were found around a 'kissing-bond' defect within the weld stirred nugget zone by means of scanning electron microscope and energy dispersive X-ray analysis. On the basis of volume conservation law in material plastic deformation, a simple empirical criterion for estimating the existence of inner material-loss defects was proposed. Defect-free butt joints were obtained after process optimization of friction stir welding for aluminum 2219-T6 plates in 17-20 mm thickness. Process experiments proved that besides of tool rotation speed and travel speed, more other appropriate process parameter variables played important roles at the formation of high-quality friction stir welds, such as tool-shoulder target depth, spindle tilt angle, and fixture clamping conditions on the work-pieces. Furthermore, the nonlinear correlation between weld tensile strengths and weld crack

The purpose of surgical literature is to publish the latest study results and to provide continuing medical education to readers. For optimal allocation of resources, institutional subscribers, professional societies and scientific publishers require structured data on reading and subscription preferences of potential readers of surgical literature. To obtain representative data on the preferences of German general and visceral surgeons regarding reading of and subscription to scientific journals. All members of the German Society for General and Visceral Surgery (DGAV) were invited to participate in a web-based survey. Questions were asked on the affiliation and position of the member, individual journal subscriptions, institutional access to scientific journals, preferences regarding electronic or print articles and special subscriptions for society members. Answers were descriptively analyzed. A total of 630 out of 4091 (15 %) members participated in the survey and 73 % of the respondents had at least 1 individual subscription to a scientific journal. The most frequently subscribed journal was Der Chirurg (47 % of respondents). The institutional access to journals was deemed insufficient by 48 % of respondents, predominantly in primary care hospitals and outpatient clinics. Almost half of the respondents gave sufficient importance to reading printed versions of articles for which they would pay extra fees. A group subscription for society members was perceived as advantageous as long as no relevant extra costs were incurred. This structured survey among members of the DGAV provides data on preferences regarding reading of and subscription to scientific journals. Individual subscriptions to journals are still common, possibly due to suboptimal institutional access particularly at smaller non-academic institutions. In an age of online publications it seems surprising that many respondents place a high value on printed versions. The results are relevant for

A Methodology for the Assessment of Unconventional (Continuous) Resources with an Application to the Greater Natural Buttes Gas Field, Utah

International Nuclear Information System (INIS)

Olea, Ricardo A.; Cook, Troy A.; Coleman, James L.

2010-01-01

The Greater Natural Buttes tight natural gas field is an unconventional (continuous) accumulation in the Uinta Basin, Utah, that began production in the early 1950s from the Upper Cretaceous Mesaverde Group. Three years later, production was extended to the Eocene Wasatch Formation. With the exclusion of 1100 non-productive ('dry') wells, we estimate that the final recovery from the 2500 producing wells existing in 2007 will be about 1.7 trillion standard cubic feet (TSCF) (48.2 billion cubic meters (BCM)). The use of estimated ultimate recovery (EUR) per well is common in assessments of unconventional resources, and it is one of the main sources of information to forecast undiscovered resources. Each calculated recovery value has an associated drainage area that generally varies from well to well and that can be mathematically subdivided into elemental subareas of constant size and shape called cells. Recovery per 5-acre cells at Greater Natural Buttes shows spatial correlation; hence, statistical approaches that ignore this correlation when inferring EUR values for untested cells do not take full advantage of all the information contained in the data. More critically, resulting models do not match the style of spatial EUR fluctuations observed in nature. This study takes a new approach by applying spatial statistics to model geographical variation of cell EUR taking into account spatial correlation and the influence of fractures. We applied sequential indicator simulation to model non-productive cells, while spatial mapping of cell EUR was obtained by applying sequential Gaussian simulation to provide multiple versions of reality (realizations) having equal chances of being the correct model. For each realization, summation of EUR in cells not drained by the existing wells allowed preparation of a stochastic prediction of undiscovered resources, which range between 2.6 and 3.4 TSCF (73.6 and 96.3 BCM) with a mean of 2.9 TSCF (82.1 BCM) for Greater Natural Buttes

Gadolinium-based contrast agents (GBCAs) have been used for magnetic resonance (MR) imaging over the last three decades. Recent reports demonstrated gadolinium retention in patients' brains following intravenous administration. Since gadolinium is a highly toxic heavy metal, there is a potential for adverse effects from prolonged retention or deposition, particularly in children. For this reason, the Society (SPR) for Pediatric Radiology Quality and Safety committee conducted a survey to evaluate the current status of GBCAs usage among pediatric radiologists. To assess the usage of GBCAs among SPR members. An online 15-question survey was distributed to SPR members. Survey questions pertained to the type of GBCAs used, protocoling workflow, requirement of renal function or pregnancy tests, and various clinical indications for contrast-enhanced MRI examinations. A total of 163 survey responses were compiled (11.1% of survey invitations), the majority of these from academic institutions in the United States. Ninety-four percent reported that MR studies are always or usually protocoled by pediatric radiologists. The most common GBCA utilized by survey respondents were Eovist (60.7%), Ablavar (45.4%), Gadovist (38.7%), Magnevist (34.4%) and Dotarem (32.5%). For several clinical indications, survey responses regarding GBCA administration were concordant with American College of Radiology (ACR) Appropriateness Criteria, including seizures, headache and osteomyelitis. For other indications, including growth hormone deficiency and suspected vascular ring, survey responses revealed potential overutilization of GBCAs when compared to ACR recommendations. Survey results demonstrate that GBCAs are administered judiciously in children, yet there is an opportunity to improve their utilization with the goal of reducing potential future adverse effects.

Science, new technology, patient care, dental reimbursement and government regulations all affect today's dental practitioners. To find out more about how such challenges may affect current private practitioners, the American Dental Association conducted the 2000 Membership Needs and Opinions Survey. A questionnaire was sent to 6,310 ADA members in January 2000 with follow-up mailings in February, March and April 2000. Data collection was completed in July 2000. The survey included questions on critical professional issues, and on perceptions of the ADA and ADA priorities. A total of 3,558 completed surveys were received for an adjusted response rate of 59.5 percent. Members rated the identified issues' level of importance to them. The top three issues included "maintaining my ability to recommend the treatment option I feel is most appropriate for my patients," "receiving fair reimbursement for the dental services I provide," and "protecting myself, my staff and my patients from communicable diseases." New dentists found other items to be more significant to them compared with members overall. Although ADA members as a whole had similar views on critical issues facing dentistry and ADA priorities, there were significant differences regarding some issues. New dentists were far more concerned about securing funds for their practice and paying off debt than were all ADA members. Minority dentists expressed greater levels of concern about certain issues than did all ADA members. When planning and implementing ADA activities, the Association should continue to take into account members' relative rankings of professional issues and note issues of special interest to selected membership subgroups.

This report documents the findings of a survey of patients who received radioactive iodine therapy and their family members. The main objective of the survey was to gain an understanding of the experience of receiving radioactive iodine from the patient and family's perspective. The data from this study helped to inform the ARCP and GMA as they developed AC-9 - Principles of the management of radionuclide therapies. A survey was distributed to 700 patients and family members through physicians at 8 sites across Canada. Locations included: Newfoundland, Nova Scotia, Ontario (2 sites), Quebec (2 sites), Manitoba and British Columbia. A total of 190 patients and 140 family members returned completed surveys. Data was analyzed separately for individuals treated as inpatients and those treated as outpatients. The results of the survey provided a perspective from patients and families about their experiences regarding radioactive iodine therapy. The data indicate variation in patients' and family members' perspectives about how precautions are to be implemented. Both patients and family members expressed the desire for more information regarding many aspects of the treatment experience. The results have implications for the development of patient information, continuing education (in particular in the areas of precaution), the provision of access to supportive and counselling services, and the importance of looking at the individual situations of patients and their families.

2014-01-01

Background Although several studies have been conducted to investigate the relationship between perceived organizational support (POS) and job performance (JP), it remains unclear whether this relationship is appropriate for faculty members at Chinese universities. The objectives of this study were to (a) examine the correlation between POS andJP; (b) identify the predictors of POS, including demographic and organizational characteristics among faculty members at a Chinese university; (c) investigate the influence of mediating factors between POS and JP; and (d) compare the findings of this study with related studies. Methods A cross-sectional questionnaire survey was used in this study. The questionnaire was administered to 700 faculty members who were randomly selected from all faculty members at six universities. A total of 581 questionnaires were obtained. A statistical model for JP was developed based on the literature review. Results The analysis results indicated that the relationship between POS and JP was mediated by job satisfaction (JS), positive affectivity (PA), and affective commitment (AC). In addition, procedural and distributive justice contribute to POS. Conclusions The study concludes that the relationship between POS and JP is mediated by JS, PA, and AC and is influenced by POS. These results can provide evidence for university administrators to improve POS and increase the JP of faculty members at universities. PMID:24624932

A wide V-groove butt weld was fabricated from Alloy 690 plates using Alloy 152 filler material, maximum allowable heat input, and very stiff strong-backs. Alloy 690 heat affected zones (HAZ) was characterized in terms of microstructure and plastic strains induced by weld shrinkage. Crack initiation tests were carried out in pure hydrogenated steam at 400 C. degrees for 4000 h. Crack growth rate tests were performed in simulated PWR primary water at a temperature of 360 C. degrees. A maximum plastic strain around 5% was measured in the vicinity of the fusion line, which decreased almost linearly with the distance from the fusion line. Crack initiation tests on Alloy 690 HAZ specimens as well as on 30% cold-rolled Alloy 690 specimens were performed in pure hydrogenated steam at 400 C. degrees (partial pressure of hydrogen = 0.7 bar) for a total of 4000 h using cylindrical notched tensile specimens, reverse U-bends and flat micro-tensile specimens. No crack initiation was detected. Stress corrosion propagation rates revealed extremely low SCC (Stress Corrosion Cracking) growth rates both in the base metal and in the HAZ region whose magnitudes are of no engineering significance. Overall, the results indicated limited plastic strain induced by weld shrinkage in butt weld HAZ, and to no particular susceptibility of primary water stress corrosion cracking. (authors)

The polytraumatic nature of traumatic brain injury (TBI) makes diagnosis and treatment difficult. To (1) characterise information needs among Veterans Health Administration (VHA) polytrauma care team members engaged in the diagnosis and treatment of TBI; (2) identify sources used for TBI related information; and (3) identify barriers to accessing TBI related information. Cross-sectional online survey of 236 VHA polytrauma care team members. Most respondents (95.8%) keep at least somewhat current regarding TBI, but 31.5% need more knowledge on diagnosing TBI and 51.3% need more knowledge on treating TBI. Respondents use VHA affiliated sources for information, including local colleagues (81.7%), VHA offsite conferences/meetings (78.3%) and onsite VHA educational offerings (73.6%); however, limited time due to administrative responsibilities (50.9%), limited financial resources (50.4%) and patient care (50.4%) were prominent barriers. Medical librarians are in a unique position to develop information services, resources and other electronic tools that reflect the clinical context in which polytrauma care team members practice, and the different tasks they perform. Polytrauma care team members could benefit from additional information regarding the diagnosis and treatment of TBI. Addressing their information needs and supporting their information seeking requires a mulit-pronged approach to time and financial constraints. Published 2017.

A worldwide consensus for timing and criteria for return to sport after anterior cruciate ligament (ACL) reconstruction is lacking. The aim of the study was to survey among the Italian Society of Knee, Arthroscopy, Sport, Cartilage and Orthopaedic Technologies (SIGASCOT) members in order to evaluate their approaches to the return to sport after ACL reconstruction regarding timing and criteria. A web survey among the SIGASCOT members was performed, including 14 questions regarding technical and graft preferences, timing for return to training and competitive activity for contact and non-contact sports and criteria to allow return to sport. Totally, 123 members completed the questionnaire. Return to training sports was allowed within 6 month by 87 % for non-contact sports and by 53 % for contact sports. Return to competitive activity was allowed within 6 months by 48 % for non-contact sports and by 13 % for contact sports. Full ROM (77 %), Lachman test (65 %) and Pivot-Shift test (65 %) were the most used criteria to allow return to sport. The 90 % used at least one clinical score. The SIGASCOT members showed various approaches in the return to sport after ACL reconstruction, with differences between return to training or competitive activity, and between contact and non-contact sports. Six months was generally considered adequate by most of the members for the most demanding activities. The most used criteria to allow return to sport were manual testing. A clear definition of sport activities and more objective criteria for the return to sport are needed. Level V, expert opinion.

Context: Prior studies have shown common use of post-operative bracing, despite advances in modern day instrumentation rigidity and little evidence of brace effectiveness. To document current practice patterns of brace use after degenerative cervical spine surgeries among members of the Cervical Spine Research Society (CSRS), to evaluate trends, and to identify areas of further study. A questionnaire survey METHODS: A 10 question survey was sent to members of the Cervical Spine Research Society to document current routine bracing practices after various common degenerative cervical spine surgical scenarios, including fusion and non-fusion procedures. The overall bracing rate was 67%. This included 8.4% who used a hard collar in each scenario. Twenty-two percent of surgeons never used a hard collar, while 34% never used a soft collar, and 3.6% (3 respondents) did not use a brace in any surgical scenario. Bracing frequency for specific surgical scenarios varied from 39% after foraminotomy to 88% after multi-level corpectomy with anterior & posterior fixation. After one, two and three level anterior cervical discectomy & fusion (ACDF), bracing rates were 58%, 65% and 76% for an average of 3.3, 4.3 and 5.3 weeks, respectively. After single level corpectomy, 77% braced for an average of 6.2 weeks. After laminectomy and fusion, 72% braced for an average of 5.4 weeks. Significant variation persists among surgeons on the type and length of post-operative brace usage after cervical spine surgeries. Overall rates of bracing have not changed significantly with time. Given the lack evidence in the literature to support bracing, reconsidering use of a brace after certain surgeries may be warranted. Copyright © 2018. Published by Elsevier Inc.

Phased Array Ultrasonic Testing (PAUT) utilizes arrays of piezoelectric elements that are embedded in an epoxy base. The benefit of having such kind of array is that beam forming such as steering and focusing the beam front possible. This enables scanning patterns such as linear scan, sectorial scan and depth focusing scan to be performed. Ultrasonic phased array systems can potentially be employed in almost any test where conventional ultrasonic flaw detectors have traditionally been used. Weld inspection and crack detection are the most important applications, and these tests are done across a wide range of industries including aerospace, power generation, petrochemical, metal billet and tubular goods suppliers, pipeline construction and maintenance, structural metals, and general manufacturing. Phased arrays can also be effectively used to profile remaining wall thickness in corrosion survey applications. The benefits of PAUT are simplifying inspection of components of complex geometry, inspection of components with limited access, testing of welds with multiple angles from a single probe and increasing the probability of detection while improving signal-to-noise ratio. This paper compares the result of inspection on several specimens using PAUT as to digital radiography. The specimens are welded plates with single V-butt weld made of carbon steel. Digital radiography is done using blue imaging plate with x-ray source. PAUT is done using Olympus MX2 with 5 MHz probe consisting of 64 elements. The location, size and length of defect is compared.

Introduction There are few studies on the experiences of spouses of military members, with most focused on adverse impacts of deployment. Responses to an open-ended question in a survey of spouses' health and wellbeing enabled access to perceptions and insights on a broad range of topics. The objective of this investigation was to examine how respondents used the open-ended question and what they discussed, in aim of informing support service agencies and spouses of military members. Methods Thematic analysis was conducted on responses to the open-ended question. Descriptive analysis was performed on the demographics, military member characteristics and self-reported health of respondents and non-respondents to the open-ended question. Findings Over a quarter (28.5%) of the 1,332 survey participants answered the open-ended question, with respondents having a significantly higher level of education than non–respondents. Respondents expressed negative and positive experiences and insights on military life, provided personal information, commented on the survey, and qualified their responses to closed-ended questions. Topics included ‘inadequate support’, ‘deployment impacts’, ‘suggestions for supporting agencies’, ‘appraisal of experiences’ and ‘coping strategies’. Conclusions This investigation uncovered issues of importance to spouses of military members that were not included or identified in a quantitative study. The findings provide a platform from which to explore these issues further, particularly the impact of military life on the non-serving spouse's career. The findings also provide support agencies with evidence to strengthen their services and they give spouses an opportunity to reflect on their own and others' feelings and evaluations of military life.

Concern for the integrity of stainless steel butt-weldments in boiling-water-reactor (BWR) piping systems has stimulated study of the conditions that cause stress corrosion cracking (SCC) in the heat-affected zones (HAZ) of the weldments. It is generally agreed that a high stress exceeding the initial yield strength is one of the essential elements for crack initiation. Since design procedures usually ensure that load stresses are below initial yield, the source of the high stresses necessary to produce SCC is thought to be the residual stresses due to welding. To examine the level of residual stresses in the weldments of interest, bulk residual stresses were measured on 100 mm (4-in.) and 254 mm (10-in.) diameter Schedule 80 piping weldments using strain relief techniques. Both laboratory welded specimens and field welded specimens from reactors in service were studied. Axial bulk residual stress distributions were obtained at 45 0 intervals around the circumference. At each azimuthal position, the residual stresses were measured at seven axial positions: on the weld centerline and 13, 20, and 25 mm on either side of the weld centerline on both the inside and outside surfaces

Nursing is the largest health care profession, and Institute of Medicine (IOM) nurse members have the potential to contribute to health policy through IOM activities. We studied reported activities of IOM nurse members. To describe activities of IOM nurse members within the IOM. An e-mail survey was conducted that asked nurse IOM members to assess self-reported IOM activities. Of 57 members, 47 had functioning e-mail addresses, and 33 usable responses were received. The survey consisted of 9 questions dealing with roles and responsibilities undertaken in the previous 5 years. Data analyses were descriptive. The data suggest that nurses have made considerable contributions to the IOM and their participation seems to be as high, or higher, than other disciplines. In an era of health care reform, there is additional opportunity for nurse IOM members to enhance their work in the IOM. Copyright © 2012 Elsevier Inc. All rights reserved.

This material give a 90, 110, 125 ampere with SMAW AC electrode diameter 3,2 mm x 350 mm with V root and 600 angle In the fabrication of mild steel products, components or equipment, manufacturers employ welding as the principal joining method. Mild steel are weldable materials, and a welded joint can provide optimum corrosion resistance, strength, and fabrication economy. However, designers should recognize that any metal, including stainless steels, may undergo certain changes during welding. It is necessary, therefore, to exercise a reasonable degree of care during welding to minimize or prevent any deleterious effects that may occur, and to preserve the same degree of corrosion resistance and strength in weld zone that is an intheren part of the base metal

Calls for disaster medical assistance teams (DMATs) are likely to continue in response to international disasters. As part of a national survey, this study was designed to evaluate Australian DMAT experience in relation to the human resources issues associated with deployment. Data was collected via an anonymous mailed survey distributed via State and Territory representatives on the Australian Health Protection Committee, who identified team members associated with Australian DMAT deployments from the 2004 South East Asian Tsunami disaster. The response rate for this survey was 50% (59/118). Most personnel had deployed to the Asian Tsunami affected areas with DMAT members having significant clinical and international experience. While all except one respondent stated they received a full orientation prior to deployment, only 34% of respondents (20/59) felt their role was clearly defined pre deployment. Approximately 56% (33/59) felt their actual role matched their intended role and that their clinical background was well suited to their tasks. Most respondents were prepared to be available for deployment for 1 month (34%, 20/59). The most common period of notice needed to deploy was 6-12 hours for 29% (17/59) followed by 12-24 hours for 24% (14/59). The preferred period of overseas deployment was 14-21 days (46%, 27/59) followed by 1 month (25%, 15/59) and the optimum shift period was felt to be 12 hours by 66% (39/59). The majority felt that there was both adequate pay (71%, 42/59) and adequate indemnity (66%, 39/59). Almost half (49%, 29/59) stated it was better to work with people from the same hospital and, while most felt their deployment could be easily covered by staff from their workplace (56%, 33/59) and caused an inconvenience to their colleagues (51%, 30/59), it was less likely to interrupt service delivery in their workplace (10%, 6/59) or cause an inconvenience to patients (9%, 5/59). Deployment was felt to benefit the affected community by nearly all

An aperture through a biological shield is sealed by a flexible sheath having a beading at one end located on an annular member slidable in the aperture such that the beading bears in sealing engagement against the sides of the aperture. The annular member is retained by a retractable latch and can be rejected by pushing it out of the aperture using a replacement annular member with a replacement sheath thereon to butt against the annular member to be rejected. The replacement annular member may be mounted on a tubular device having an outer co-axial member for operating the latch when the replacement annular member butts against the annular member to be rejected. Applications include effecting a seal between a remote handling equipment and a wall through which the equipment extends. (author)

Residual stress in a thick section high strength T-butt weld

International Nuclear Information System (INIS)

Pearce, S.V.; Linton, V.M.; Oliver, E.C.

2008-01-01

Residual stresses in a structure are generated as a result of the various fabrication and welding processes used to make the component. Being able to quantify these residual stresses is a key step in determining the continuing integrity of a structure in service. In this work, the residual stresses around a high strength, quenched and tempered steel T-butt web to curved plate weld have been measured using neutron strain scanning. The results show that the residual stresses near the weld were dominated by the welding residual stresses, while the stresses further from the weld were dominated by the bending residual stresses. The results suggest that the combination of welding-induced residual stress and significant pre-welding residual stress, as in the case of a thick bent section of plate can significantly alter the residual stress profile from that in a flat plate

Analysis of willingness for postmortem cornea donation by professionals in ophthalmology and their motives in favor of or against donation. 3887 members of the German Ophthalmological Society received an anonymous questionnaire concerning sociodemographic background, physical health, experiences with organ explantation and their former engagement and motives concerning organ and cornea donation. 722 of the questionnaires were partially and 533 completely answered with an average willingness for cornea donation of 79.4%. Significant parameters for cornea donation were gender, former experience with organ explantation, ophthalmological health and fear of false diagnosis of brain death, worse medical treatment or organ commercialization. Of the participants 53.9% suggested the internet as a favorite source of information in this matter. The factors which had a significant impact on cornea donation in this survey seem to be mainly a result of insufficient information. Detailed information regarding this topic should preferentially be presented on internet pages of professional societies and could probably increase donation approval of DOG members.

Objective. The objective of this survey was to explore the attitudes towards plagiarism of faculty members and medical students in Pakistan. Methods. The Attitudes Toward Plagiarism questionnaire (ATP) was modified and distributed among 550 medical students and 130 faculty members in 7 medical colleges of Lahore and Rawalpindi. Data was entered in the SPSS v.20 and descriptive statistics were analyzed. The questionnaire was validated by principal axis factoring analysis. Results. Response rate was 93% and 73%, respectively. Principal axis factoring analysis confirmed one factor structure of ATP in the present sample. It had an acceptable Cronbach’s alpha value of 0.73. There were 421 medical students (218 (52%) female, 46% 3rd year MBBS students, mean age of 20.93 ± 1.4 years) and 95 faculty members (54.7% female, mean age 34.5 ± 8.9 years). One fifth of the students (19.7%) trained in medical writing (19.7%), research ethics (25.2%) or were currently involved in medical writing (17.6%). Most of the faculty members were demonstrators (66) or assistant professors (20) with work experience between 1 and 10 years. Most of them had trained in medical writing (68), research ethics (64) and were currently involved in medical writing (64). Medical students and faculty members had a mean score of 43.21 (7.1) and 48.4 (5.9) respectively on ATP. Most of the respondents did not consider that they worked in a plagiarism free environment and reported that self-plagiarism should not be punishable in the same way as plagiarism. Opinion regarding leniency in punishment of younger researchers who were just learning medical writing was divided. Conclusions. The general attitudes of Pakistani medical faculty members and medical students as assessed by ATP were positive. We propose training in medical writing and research ethics as part of the under and post graduate medical curriculum. PMID:26157615

Effective communication enhances team building and is perceived to improve the quality of team performance. A recent publication from the Resuscitation Council (UK) has highlighted this fact and recommended that cardiac arrest team members make contact daily. We wished to identify how often members of this team communicate prior to a cardiopulmonary arrest. A questionnaire on cardiac arrest team composition, leadership, communication and debriefing was distributed nationally to Resuscitation Training Officers (RTOs) and their responses analysed. One hundred and thirty (55%) RTOs replied. Physicians and anaesthetists were the most prominent members of the team. The Medical Senior House Officer is usually nominated as the team leader. Eighty-seven centres (67%) have no communication between team members prior to attending a cardiopulmonary arrest. In 33%, communication occurs but is either informal or fortuitous. The RTOs felt that communication is important to enhance team dynamics and optimise task allocation. Only 7% achieve a formal debrief following a cardiac arrest. Communication between members of the cardiac arrest team before and after a cardiac arrest is poor. Training and development of these skills may improve performance and should be prioritised. Team leadership does not necessarily reflect experience or training.

A 1.55 μm InGaAsP/InGaAsP multiple-quantum-well electro-absorption modulator (EAM) monolithically integrated with a distributed feedback laser (DFB) diode has been realized based on a novel butt-joint scheme by ultra-low metal-organic vapour phase epitaxy for the first time. The threshold current of 25 mA and an extinction ratio of more than 30 dB are obtained by using the novel structure. The beam divergence angles at the horizontal and vertical directions are as small as 19.3 deg. x 13 deg., respectively, without a spot-size converter by undercutting the InGaAsP active region. The capacitance of the ridge waveguide device with a deep mesa buried by polyimide was reduced down to 0.30 pF

We present the results of a direct imaging survey for very large separation (>100 au), low-mass companions around 95 nearby young K5-L5 stars and brown dwarfs. They are high-likelihood candidates or confirmed members of the young (≲150 Myr) β Pictoris and AB Doradus moving groups (ABDMG) and the TW Hya, Tucana-Horologium, Columba, Carina, and Argus associations. Images in I\\prime and z\\prime filters were obtained with the Gemini Multi-Object Spectrograph (GMOS) on Gemini South to search for companions down to an apparent magnitude of z\\prime ˜ 22-24 at separations ≳20″ from the targets and in the remainder of the wide 5.‧5 × 5.‧5 GMOS field of view. This allowed us to probe the most distant region where planetary-mass companions could be gravitationally bound to the targets. This region was left largely unstudied by past high-contrast imaging surveys, which probed much closer-in separations. This survey led to the discovery of a planetary-mass (9-13 {M}{Jup}) companion at 2000 au from the M3V star GU Psc, a highly probable member of ABDMG. No other substellar companions were identified. These results allowed us to constrain the frequency of distant planetary-mass companions (5-13 {M}{Jup}) to {0.84}-0.66+6.73% (95% confidence) at semimajor axes between 500 and 5000 au around young K5-L5 stars and brown dwarfs. This is consistent with other studies suggesting that gravitationally bound planetary-mass companions at wide separations from low-mass stars are relatively rare.

Reduced funding to public health care systems during economic downturns is a common phenomenon around the world. The effect of health care cost on family members of the patients has not been established. This paper aims to explore the relationship between affordability of health care and vulnerability of family members to distress levels. Data of a total of 262,843 participants were obtained from 17 waves (1997-2013) of the United States National Health Interview Survey. Multinomial logistic regression was used to investigate psychological distress level as a result of having family members who experienced unmet medical needs due to cost. Among participants without family members who experienced unmet needs for medical care due to cost, risks of having 'moderate' (score of 5-12) or 'serious' (score of 13 or above) level of psychological distress were 1.0% and 11.5%, respectively. Risks of having 'moderate' or 'serious' level of psychological distress were 3.1% and 23.4%, respectively among participants with family members who experienced unmet needs. The adjusted relative risk ratio of 'moderate' and 'serious', as compared to 'normal' level of psychological distress, were 1.58 (95% confidence interval: 1.47-1.69) and 2.09 (95% confidence interval: 1.78-2.45) if one's family members experienced unmet medical needs. Unmet medical needs due to cost increases risk of distress levels experienced by family members. Careful planning and adequate funding to public health care system could be implemented to prevent any unnecessary detrimental effect on mental health among family members of the unwell and any further increment of the prevalence of mental illnesses. This recommendation aligns with the World Health Organization Mental Health Action Plan 2013-2020.

Wired for success: A history of the Butte, Anaconda & Pacific Railway, 1892--1985

Science.gov (United States)

Mutschler, Charles Vincent

The Butte, Anaconda & Pacific Railway (BA&P) was a standard gauge common carrier short line railroad within the state of Montana. A subsidiary of the Anaconda Copper Mining Company, the BA&P was built to carry ore from mines at Butte, Montana to Anaconda, twenty-six miles away, for concentrating and smelting. Other freight and passenger business was of secondary importance. In 1912, when General Electric contracted to convert the BA&P from steam to electric operation, the short line became a proving ground for main line railroad electrification, and the center of attention from advocates for electric power. Electric operation was demonstrated to be mechanically superior to the use of steam locomotives on the BA&P. Immediately after the BA&P proved the technological feasibility of high voltage direct current for moving heavy freight trains, the Chicago Milwaukee & St. Paul (CM&St.P) electrified over 600 miles of transcontinental main line using the basic technology demonstrated on the BA&P. However, on long distances of track with relatively few trains such as the CM&St.P, the capital cost of the electric distribution system exceeded the operational savings obtained by use of electric locomotives. Steam locomotives remained the primary form of railroad motive power in the United States until the 1950's, when the diesel-electric locomotive combined the mechanical efficiency of electric motors with an on-board diesel generating plant, eliminating the need for expensive electric power supply and distribution wires of conventional electrics. The BA&P purchased three diesels in the early 1950's, but relied primarily on its electric locomotives until 1967, when diesel operation became less costly than continued use of electric motive power. The BA&P offers a microcosmic view of the transformation of one industry in response to technological and economic forces as the United States moved from reliance on coal-burning steam power to electric power and internal combustion

Background/Significance Initial therapy for craniopharyngioma remains controversial. Population-based datasets indicate that traditional algorithms (GTR versus STR +/− XRT) are often not employed. We investigated neurosurgical practice patterns. Methods A ten-question survey was electronically distributed to members of the American Association of Neurological Surgeons. Responses were analyzed using standard statistical techniques. Results One hundred-two responses were collected, with a median 25 craniopharyngiomas managed per respondent. 36% estimated their practice included ≥75% pediatrics and 61% had an academic practice. 36% would recommend observation or radiation therapy for a suspected craniopharyngioma in the absence of a tissue diagnosis, with 46% of these indicating this recommendation in ≥10% of cases. Following STR, 35% always recommend XRT and 59% recommend it in over half of cases. However, following STR or biopsy alone, 18% and 11% never recommend XRT. There was no association between type of practice (i.e. academic or ≥75% pediatrics) and practice patterns. Conclusions This survey verifies that deviation from established algorithms is common, underscoring the clinical complexity of these patients and recent secondary data analyses This should influence clinical researchers to investigate outcomes for patients treated using alternative methods. This will lend insight into appropriate treatment options and contribute to quality of life outcomes studies for craniopharyngioma. PMID:24577430

Purpose: To assess current education, practices, attitudes, and perceptions pertaining to ethics and professionalism in medical physics. Methods: A link to a web-based survey was distributed to the American Association of Physicists in Medicine (AAPM) e-mail membership list, with a follow-up e-mail sent two weeks later. The survey included questions about ethics/professionalism education, direct personal knowledge of ethically questionable practices in clinical care, research, education (teaching and mentoring), and professionalism, respondents’ assessment of their ability to address ethical/professional dilemmas, and demographics. For analysis, reports of unethical or ethically questionable practices or behaviors by approximately 40% or more of respondents were classified as “frequent.” Results: Partial or complete responses were received from 18% (1394/7708) of AAPM members. Overall, 60% (827/1377) of the respondents stated that they had not received ethics/professionalism education during their medical physics training. Respondents currently in training were more likely to state that they received instruction in ethics/professionalism (80%, 127/159) versus respondents who were post-training (35%, 401/1159). Respondents’ preferred method of instruction in ethics/professionalism was structured periodic discussions involving both faculty and students/trainees. More than 90% (1271/1384) supported continuing education in ethics/professionalism and 75% (1043/1386) stated they would attend ethics/professionalism sessions at professional/scientific meetings. In the research setting, reports about ethically questionable authorship assignment were frequent (approximately 40%) whereas incidents of ethically questionable practices about human subjects protections were quite infrequent (5%). In the clinical setting, there was frequent recollection of incidents regarding lack of training, resources and skills, and error/incident reporting. In the educational setting

The purpose of this study was to examine the association between members' perceptions of staffs behaviors, motivational climate, their own behaviors, commitment to future exercise, and life satisfaction in a group-fitness setting. The theory-driven hypothesized mediating role of perceptions of the climate was also tested. Members (N = 5,541) of a national group-fitness studio franchise completed a survey regarding their class experiences. The survey included questions that measured participants' perceptions of the motivational climate (caring, task-involving, ego-involving), perceptions of staff's behaviors, their own behaviors, commitment to exercise, and life satisfaction. Structural equation modeling was used to assess both the association between variables and the theoretically driven predictive relationships. The participants perceived the environment as highly caring and task-involving and low ego-involving. They reported high exercise commitment and moderately high life satisfaction and perceived that the staffs and their own behaviors reflected caring, task-involving characteristics. Structural equation modeling demonstrated that those who perceived a higher caring, task-involving climate and lower ego-involving climate were more likely to report more task-involving, caring behaviors among the staff and themselves as well as greater commitment to exercise. In addition, a theory-driven mediational model suggested that staff behaviors may be an antecedent to members' exercise experiences by impacting their perceptions of the climate. The results of this study give direction to specific behaviors in which staff of group-fitness programs might engage to positively influence members' exercise experiences.

Effect of post-weld heat treatment on the weld microstructure, texture, and its correlation to the toughness of flash butt welded joints were investigated. Upon flash butt welding, the α and γ-fiber in the parent material converted to Goss (110)[001], rotated Goss (110)[1 \\bar{1} 0], and rotated cube (001)[1 \\bar{1} 0], (001)[ \\overline{11} 0] textures along the fracture plane. Formation of these detrimental texture components was a result of shear deformation and recrystallization of austenite at temperatures above T nr resulting in a drop of toughness at the weld zone. Inter-critical and sub-critical annealing cycles proved to be less effective in reducing the Goss (110)[001], rotated Goss (110)[1 \\bar{1} 0], and rotated cube (001)[1 \\bar{1} 0], (001)[ \\overline{11} 0] texture components, and therefore, toughness values remained unaffected. Post-weld heat treatment in the austenite phase field at 1000 °C for 5 seconds resulted in the formation of new grains with different orientations leading to a reduction in the texture intensities of both Goss and rotated Goss components and therefore improved weld zone toughness. Prolonged annealing time was found to be ineffective in improving the toughness due to grain growth.

Cigarette butts and other postconsumer products from tobacco use are the most common waste elements picked up worldwide each year during environmental cleanups. Under the environmental principle of Extended Producer Responsibility, tobacco product manufacturers may be held responsible for collection, transport, processing and safe disposal of tobacco product waste (TPW). Legislation has been applied to other toxic and hazardous postconsumer waste products such as paints, pesticide containers and unused pharmaceuticals, to reduce, prevent and mitigate their environmental impacts. Additional product stewardship (PS) requirements may be necessary for other stakeholders and beneficiaries of tobacco product sales and use, especially suppliers, retailers and consumers, in order to ensure effective TPW reduction. This report describes how a Model Tobacco Waste Act may be adopted by national and subnational jurisdictions to address the environmental impacts of TPW. Such a law will also reduce tobacco use and its health consequences by raising attention to the environmental hazards of TPW, increasing the price of tobacco products, and reducing the number of tobacco product retailers.

Polycarbonate sheets, 3 mm thick, were successfully friction stir welded in butt joint configuration. Aiming to study the feasibility of the process and the influence of the process parameters joints under different processing conditions, obtained by varying the tool rotational speed and the tool travel speed, were realized. Tensile tests were carried out to characterize the joints. Moreover the forces arising during the process were recorded and carefully studied. The experimental outcomes proved the feasibility of the process when the process parameters are properly set, joints retaining more than 70% of the UTS of the base material were produced. The trend of the forces was described and explained, the influence of the process parameters was also introduced.

Full Text Available  Ischemic stroke secondary to aortic dissection is not uncommon. We present a patient with left hemiplegia secondary to Stanford type A aortic dissection extending to the supra-aortic vessels, which was precipitated by rifle butt recoil chest injury. The diagnosis of aortic dissection was delayed due to various factors. Finally, the patient underwent successful Bentall procedure with complete resolution of symptoms. This case emphasizes the need for caution in the use of firearms for recreation and to take precautions in preventing such incidents. In addition, this case illustrates the need for prompt cardiovascular physical examination in patients presenting with stroke.

Females currently make up 15% of U.S. military service members. Minimal attention has been paid to families of female National Guard members who have been deployed and their subsequent reintegration challenges. This cross-sectional Internet-based survey of female members of four National Guard units compared those who were and were not deployed. Instruments, guided by the variables of the Family Resilience Model, measured individual, family, and deployment-related factors. Bivariate analysis and ordinal logistic regression were done to assess differences between the groups. Of the 239 National Guard members surveyed, deployed women (n = 164) had significantly higher levels of posttraumatic stress disorder (PTSD; p family functioning were higher among deployed when compared with never deployed women. Results indicate community interventions that focus on strengthening coping skills of female Guard members would be useful for this population. © The Author(s) 2016.

Busted Butte Phase 2: Introduction and Analytical Modeling of Nonreactive Tracer and Lithium Breakthrough

International Nuclear Information System (INIS)

Turin, H.J.; Soll, W.E.

2002-01-01

The Busted Butte Unsaturated-Zone Transport Test Facility is located approximately 8 km southeast of Yucca Mountain, and was designed to address uncertainties associated with flow and transport in the UZ site-process models for Yucca Mountain. Busted Butte Phase 2 consisted of a 10m x 10m x 7m test block. From July 1988 through October 2000, complex tracer mixtures were injected continuously at 77 discrete points located along eight parallel 10-m boreholes arranged in two horizontal planes. In August 1999, iodide was added to the tracer mixture to explore the effects of initial hydraulic transients. During the course of the experiment, porewater samples were collected at regular intervals using sorbing-paper collection pads, emplaced into fifteen horizontal and inclined 10-m collection boreholes, oriented perpendicular to the injection boreholes. Potential travel distances ranged from 20 cm to over 500 cm. Nonreactive tracer and weakly sorbing lithium breakthrough was observed at most of the collection points during the injection period. Following termination of injection, approximately 800 rock samples were collected using overcore and mineback techniques, and analyzed for tracer concentration. Rock analyses are discussed in a subsequent paper. To complement complex 3-dimensional finite-element modeling of the entire block, bromide, iodide, and lithium breakthrough onto the collection pads has been modeled with CXTFIT. This simple 1-dimensional analytical code uses a non-linear curve-fitting routine to estimate transport parameters including apparent velocity, dispersivity, and field retardation factors. Preliminary results show that: (1) Bromide and iodide behaved similarly, despite the fact that bromide was injected in a strongly transient flow field, while iodide injection began after flow had approached steady state conditions. (2) With the exception of the closest collection points, tracer velocities remained relatively constant, indicating that transport was

Graphical abstract: Three different microstructural zones formed at different distances from the joint interface in resistance upset butt welding of 304 austenitic stainless steel. Highlights: → Evaluation of microstructure in resistance upset welding of 304 stainless steel. → Evaluation of welding parameters effects on mechanical properties of the joint. → Introducing the optimum welding condition for joining stainless steel bars. -- Abstract: Resistance upset welding (UW) is a widely used process for joining metal parts. In this process, current, time and upset pressure are three parameters that affect the quality of welded products. In the present research, resistance upset butt welding of 304 austenitic stainless steel and effect of welding power and upset pressure on microstructure, tensile strength and fatigue life of the joint were investigated. Microstructure of welds were studied using scanning electron microscopy (SEM). X-ray diffraction (XRD) analysis was used to distinguish the phase(s) that formed at the joint interface and in heat affected zone (HAZ). Energy dispersive spectroscopy (EDS) linked to the SEM was used to determine chemical composition of phases formed at the joint interface. Fatigue tests were performed using a pull-push fatigue test machine and the fatigue properties were analyzed drawing stress-number of cycles to failure (S-N) curves. Also tensile strength tests were performed. Finally tensile and fatigue fracture surfaces were studied by SEM. Results showed that there were three different microstructural zones at different distances from the joint interface and delta ferrite phase has formed in these regions. There was no precipitation of chromium carbide at the joint interface and in the HAZ. Tensile and fatigue strengths of the joint decreased with welding power. Increasing of upset pressure has also considerable influence on tensile strength of the joint. Fractography of fractured samples showed that formation of hot spots at

The technique of chemical tagging uses the elemental abundances of stellar atmospheres to 'reconstruct' chemically homogeneous star clusters that have long since dispersed. The GALAH spectroscopic survey - which aims to observe one million stars using the Anglo-Australian Telescope - allows us to measure up to 30 elements or dimensions in the stellar chemical abundance space, many of which are not independent. How to find clustering reliably in a noisy high-dimensional space is a difficult problem that remains largely unsolved. Here, we explore t-distributed stochastic neighbour embedding (t-SNE) - which identifies an optimal mapping of a high-dimensional space into fewer dimensions - whilst conserving the original clustering information. Typically, the projection is made to a 2D space to aid recognition of clusters by eye. We show that this method is a reliable tool for chemical tagging because it can: (i) resolve clustering in chemical space alone, (ii) recover known open and globular clusters with high efficiency and low contamination, and (iii) relate field stars to known clusters. t-SNE also provides a useful visualization of a high-dimensional space. We demonstrate the method on a data set of 13 abundances measured in the spectra of 187 000 stars by the GALAH survey. We recover seven of the nine observed clusters (six globular and three open clusters) in chemical space with minimal contamination from field stars and low numbers of outliers. With chemical tagging, we also identify two Pleiades supercluster members (which we confirm kinematically), one as far as 6° - one tidal radius away from the cluster centre.

Family members are often the primary caregiver for autistic adults and this responsibility may impact on the carer's wellbeing and quality of life. 109 family members of autistic adults completed an online survey assessing their wellbeing relating to their caring role for their autistic relative. Family members who were supporting an autistic relative with co-occurring mental health difficulties and who they reported as unprepared for the future, self-reported higher levels of worry, depression, anxiety and stress, and poorer quality of life. These findings emphasise the importance of support for family members of autistic adults, whether through external services to support their relative or individual mental health support for the carer.

On detection and automatic tracking of butt weld line in thin wall pipe welding by a mobile robot with visual sensor

International Nuclear Information System (INIS)

Suga, Yasuo; Ishii, Hideaki; Muto, Akifumi

1992-01-01

An automatic pipe welding mobile robot system with visual sensor was constructed. The robot can move along a pipe, and detect the weld line to be welded by visual sensor. Moreover, in order to make an automatic welding, the welding torch can track the butt weld line of the pipes at a constant speed by rotating the robot head. Main results obtained are summarized as follows: 1) Using a proper lighting fixed in front of the CCD camera, the butt weld line of thin wall pipes can be recongnized stably. In this case, the root gap should be approximately 0.5 mm. 2) In order to detect the weld line stably during moving along the pipe, a brightness distribution measured by the CCD camera should be subjected to smoothing and differentiating and then the weld line is judged by the maximum and minimum values of the differentials. 3) By means of the basic robot system with a visual sensor controlled by a personal computer, the detection and in-process automatic tracking of a weld line are possible. The average tracking error was approximately 0.2 mm and maximum error 0.5 mm and the welding speed was held at a constant value with error of about 0.1 cm/min. (author)

Purpose: Sixty-seven patients with early-stage breast cancer were treated in a Phase I/II clinical trial using a 103 Pd permanent breast seed implant as adjuvant radiotherapy after breast-conserving surgery. We report the dose received by family members living with these patients and compare measured doses with theoretical worst-case scenario estimates. Methods and Materials: Exposure-rate measurements were taken at 1 m from the patient by using a calibrated low-energy survey meter. Landauer (Landauer Inc., Glenwood, IL) Luxel badges, with sensitivity of 0.01 mSv, were given to family members to wear after the implantation. Badge readings for 33 spouses and 28 other family members were used to estimate effective doses, and these were compared with theory. Results: Average preimplantation planning target volume from computed tomography was 50.3 ml (range, 18.0-96.7 ml), and average preimplantation distance between the skin and the most anterior planning target volume margin was 0.57 cm. The average maximum exposure rate was measured to be 2.4 ± 1.1 mR/h, and average measured dose to a spouse was 0.99 ± 1.0 mSv. The calculated exposure rates and spousal doses using preimplantation computed tomography scan data overestimated those measured. Average measured family member dose (excluding spouses) was 0.20 ± 0.58 mSv. Conclusions: Based on measured and calculated spousal doses, a permanent breast seed implant using 103 Pd is safe for the public. However, it is recommended that extra precautions in the way of a breast patch be used when patients with an implant will be in the vicinity of toddlers or pregnant women

Prevalence and interest in the practice of scratch testing for contact urticaria: a survey of the American contact dermatitis society members.

Contact urticaria (CU) is the development of a wheal and flare on the skin after topical exposure to a particular chemical or compound. It can be diagnosed through a variety of techniques. Many chemicals that cause a type IV allergy can also cause CU. The incidence of CU to these chemicals is unknown. The aim of this study was to evaluate the opinions of the American Contact Dermatitis Society members regarding CU and scratch testing. We distributed an electronic survey to the American Contact Dermatitis Society members regarding observed prevalence of CU, frequency of scratch testing in clinical practice, and interest in learning about scratch testing in diagnosing CU and other skin contact conditions. We distributed 508 surveys and received 133 responses. Seventeen percent reported that CU was extremely rare, 32% reported that CU was rare, and 38.9% reported that CU was infrequent. Alternatively, 10.7% believed that CU was common, and 1.5% believed that CU was extremely common. A minority, 19.1%, performed scratch testing on patients with suspected CU. Most respondents, 54.6%, were interested in learning about scratch testing. Additional education regarding scratch testing could increase comfort and use of scratch testing in clinical practice. Further studies are needed to evaluate the prevalence of CU in the general population and better guide the use of testing for dermatologic patients.

Bush, Nigel E; Wheeler, William M

2015-04-01

Although personal electronic devices, such as mobile phones, computers, and tablets, increasingly are being leveraged as vehicles for health in the civilian world, almost nothing is known about personal technology use in the U.S. military. In 2012 we conducted a unique survey of personal technologies used by U.S. military service members. However, with the rapidly growing sophistication of personal technology and changes in consumer habits, that knowledge must be continuously updated to be useful. Accordingly, we recently surveyed new samples of active duty service members, National Guard and Reserve, and veterans. We collected data by online surveys in 2013 from 239 active, inactive, and former service members. Online surveys were completed in-person via laptop computers at a large military installation and remotely via Web-based surveys posted on the Army Knowledge Online Web site and on a Defense Center Facebook social media channel. We measured high rates of personal technology use by service members at home across popular electronic media. The most dramatic change since our earlier survey was the tremendous increase in mobile phone use at home for a wide variety of purposes. Participants also reported moderate non-work uses of computers and tablets while on recent deployment to Iraq and Afghanistan, but almost no mobile phone use, ostensibly because of military restrictions in the war zone. These latest results will enable researchers and technology developers target their efforts on the most promising and popular technologies for psychological health in the military.

Composite Sunrise Butte pluton: Insights into Jurassic–Cretaceous collisional tectonics and magmatism in the Blue Mountains Province, northeastern Oregon

The composite Sunrise Butte pluton, in the central part of the Blue Mountains Province, northeastern Oregon, preserves a record of subduction-related magmatism, arc-arc collision, crustal thickening, and deep-crustal anatexis. The earliest phase of the pluton (Desolation Creek unit) was generated in a subduction zone environment, as the oceanic lithosphere between the Wallowa and Olds Ferry island arcs was consumed. Zircons from this unit yielded a 206Pb/238U age of 160.2 ± 2.1 Ma. A magmatic lull ensued during arc-arc collision, after which partial melting at the base of the thickened Wallowa arc crust produced siliceous magma that was emplaced into metasedimentary rocks and serpentinite of the overthrust forearc complex. This magma crystallized to form the bulk of the Sunrise Butte composite pluton (the Sunrise Butte unit; 145.8 ± 2.2 Ma). The heat necessary for crustal anatexis was supplied by coeval mantle-derived magma (the Onion Gulch unit; 147.9 ± 1.8 Ma).The lull in magmatic activity between 160 and 148 Ma encompasses the timing of arc-arc collision (159–154 Ma), and it is similar to those lulls observed in adjacent areas of the Blue Mountains Province related to the same shortening event. Previous researchers have proposed a tectonic link between the Blue Mountains Province and the Klamath Mountains and northern Sierra Nevada Provinces farther to the south; however, timing of Late Jurassic deformation in the Blue Mountains Province predates the timing of the so-called Nevadan orogeny in the Klamath Mountains. In both the Blue Mountains Province and Klamath Mountains, the onset of deep-crustal partial melting initiated at ca. 148 Ma, suggesting a possible geodynamic link. One possibility is that the Late Jurassic shortening event recorded in the Blue Mountains Province may be a northerly extension of the Nevadan orogeny. Differences in the timing of these events in the Blue Mountains Province and the Klamath–Sierra Nevada Provinces suggest that

2017-10-01

This study surveyed the antibiotic prescribing practices of endodontists, and data were compared with previous surveys conducted in 1994 and 1999. A 17-question survey was sent via www.surveymonkey.com to 3000 active members of the American Association of Endodontists for responses about antibiotic prescribing practices and demographics. The data were analyzed using descriptive statistics, chi-square tests, and linear regression analyses. Six hundred eighty-six participants (22.86%) completed the survey. The most frequently prescribed antibiotics were amoxicillin (60.71%) followed by penicillin V (30.43%) and clindamycin for patients with allergies (95.4%). Respondents reported prescribing antibiotics for irreversible pulpitis with mild symptoms (1.75%), irreversible pulpitis with moderate symptoms (6.41%), necrotic pulp with symptomatic apical periodontitis (43.59%), chronic apical abscess without (10.50%) or with symptoms (29.74%), acute apical abscess (95.92%), avulsion (70.26%), endodontic surgery (41.69%), retreatment (silver point [23.76%] or gutta-percha [15.60%]), postoperative pain after instrumentation or obturation (12.39%), and perforation repair (5.98%). The type of practice (solo/group) and geographic region (Southeast) were significant predictors of increased antibiotic prescribing; 36.89% of respondents reported prescribing antibiotics that are not necessary, most commonly because of patient expectations. Since 1999, there has been a significant shift from prescribing penicillin V to amoxicillin as endodontists' first choice of antibiotic and a significant increase in the use of clindamycin for penicillin-allergic patients. Antibiotics continue to be prescribed in clinical situations for which they are typically not indicated, most commonly because of patient expectations. Regional differences in antibiotic prescribing practices by endodontists exist in the United States. Copyright © 2017 American Association of Endodontists. Published by Elsevier

Aluminum 6060-T6 friction stir welded butt joints: fatigue resistance with different tools and feed rates

International Nuclear Information System (INIS)

Baragetti, S.; D'Urso, G.

2014-01-01

The fatigue behavior of AA6060-T6 friction stir welded butt joints was investigated. The joints were produced by using both a standard and a threaded tri-flute cylindrical-tool with flat shoulder. The friction stir welding process was carried out using different feed rates. Preliminary tensile tests, micrograph analyses and hardness profile measurements across the welds were carried out. Welded and unwelded fatigue samples were tested under axial loading (R = 0.1) with upper limits of 10 4 and 10 5 cycles, using threaded and unthreaded (standard) tools at different feed rates. The best tensile and fatigue performance was obtained using the standard tool at low feed rate.

Large coal reserves are present in three areas located between 12 and 20 miles southeast of Riverton, Fremont County, central Wyoming. Coal in two of these areas, the Alkali Butte coal field and the Big Sand Draw coal field, is exposed on the surface and has been developed to some extent by underground mining. The Beaver Creek coal field is known only from drill cuttings and cores from wells drilled for oil and gas in the Beaver Creek oil and gas field.These three coal areas can be reached most readily from Riverton, Wyo. State Route 320 crosses Wind River about 1 mile south of Riverton. A few hundred yards south of the river a graveled road branches off the highway and extends south across the Popo Agie River toward Sand Draw oil and gas field. About 8 miles south of the highway along the Sand Draw road, a dirt road bears east and along this road it is about 12 miles to the Bell coal mine in the Alkali Butte coal field. Three miles southeast of the Alkali Butte turn-off, 3 miles of oiled road extends southwest into the Beaver Creek oil and gas field. About 6 miles southeast of the Beaver Creek turn-off, in the valley of Little Sand Draw Creek, a dirt road extends east 1. mile and then southeast 1 mile to the Downey mine in the Big Sand Draw coal field. Location of these coal fields is shown on figure 1 with their relationship to the Wind River basin and other coal fields, place localities, and wells mentioned in this report. The coal in the Alkali Butte coal field is exposed partly on the Wind River Indian Reservation in Tps. 1 and 2 S., R. 6 E., and partly on public land. Coal in the Beaver Creek and Big Sand Draw coal fields is mainly on public land. The region has a semiarid climate with rainfall averaging less than 10 in. per year. When rain does fall the sandy-bottomed stream channels fill rapidly and are frequently impassable for a few hours. Beaver Creek, Big Sand Draw, Little Sand Draw, and Kirby Draw and their smaller tributaries drain the area and flow

The aims of this study were to estimate the prevalence of smoking among SEPAR members, and their approach to smoking cessation in their patients. An online survey was completed by 640 members (496 pulmonologists, 45 nurses, 34 thoracic surgeons, 37 physiotherapists, and 28 other specialists). Of the members interviewed, 5% confessed that they were smokers: 3.5% pulmonologists; 8.9% nurses; 8.8% thoracic surgeons, and 13.5% physiotherapists. A total of 96% of members assign a lot or quite a lot of importance to setting an example; 98% of members always or often ask their patients about their smoking habit. The most effective anti-smoking intervention, according to 77% of members, is a combination of drugs and psychological support. These results are an indicator of the awareness and commitment of SEPAR members to smoking and its cessation. Copyright © 2016 SEPAR. Publicado por Elsevier España, S.L.U. All rights reserved.

Massachusetts Medicaid members that smoked in 2008: Characteristics associated with smoking status in 2014.

Directory of Open Access Journals (Sweden)

Alexis D Henry

Full Text Available The smoking rate among non-elderly Medicaid enrollees is more than double the rate for those privately insured; smoking-related conditions account for 15% of Medicaid expenditures. Under state health reform, Massachusetts Medicaid (MassHealth made tobacco cessation treatment available beginning in 2006. We used surveys conducted in 2008 and 2014 to examine changes in smoking abstinence rates among MassHealth members identified as smokers and to identify factors associated with being a former smoker. Members previously identified as smokers were surveyed by mail or phone; 2008 and 2014 samples included 3,116 and 2,971 members, respectively. Surveys collected demographic and health information, asked members whether they smoked cigarettes "every day, some days or not at all', and asked questions to assess smoking intensity among current smokers. The 2014 survey included an open ended-question asking members "what helped the most" in quitting or quit attempts. We observed a significant decrease in members reporting smoking "every/some days" of 15.5 percentage points (p < .0001 from 2008 to 2014, and a significant decrease in smokers reporting smoking "more than 10 cigarettes on days smoked" of 16.7 percentage points (p < .0001. Compared to smokers, former smokers more frequently reported health concerns, the influence of family members, and the use of e-cigarettes as helping the most in quitting. Expanded access to tobacco cessation treatment under the Affordable Care Act may have help to reduce the high smoking rates among Medicaid enrollees. Additionally, smokers' concerns about health and the influence of family and friends provide opportunities for targeted intervention and messaging about quitting.

Current organizational guidelines regarding use of antibiotics during urinary tract catheterization are based on limited evidence and are not directly applicable to the pediatric urology population. We seek to improve understanding of this population by first evaluating current practices. This study aims to investigate practice patterns and attitudes of pediatric urologists regarding the use of antibiotics in the setting of urinary tract catheterization. An online survey was sent to members of the Society for Pediatric Urology. Questionnaire sections included demographics, general questions about antibiotic use with catheterization, and specific clinical scenarios. Descriptive statistics were used, and chi-square analysis was performed to examine associations between demographics and specific responses. Of 448 pediatric urologists surveyed, 154 (34%) responded to the survey. A majority of surveyed urologists (78%) prescribe daily prophylactic antibiotics with a hypospadias stent in place, but extensive variation in use of antibiotics was reported with other catheters and tubes. Extensive variation in practice patterns was also reported for three case scenarios regarding antibiotic prophylaxis with catheterization. Urologists > 50 years of age and fellowship-trained urologists were more likely to prescribe antibiotics for hypospadias stents (p = 0.02, p = 0.03), but no other significant associations between demographic characteristics and antibiotic use were found. There is substantial variation in practice patterns among surveyed pediatric urologists regarding prophylactic antibiotic use with urinary catheterization. This variation, combined with a lack of objective data and increasing pressure to decrease infectious complications and combat antibiotic resistance, highlights the need for development of management guidelines for this unique population.

Public Stigma Toward Mental Illness in Jordan: A Cross-Sectional Survey of Family Members of Individuals With Schizophrenia, Depression, and Anxiety.

Science.gov (United States)

Hasan, Abd Al-Hadi; Musleh, Mahmoud

2017-06-01

Stigma affects family members of individuals with mental illness. A survey of 640 family members of individuals with mental illness was conducted. Three factors were found to influence stigma regarding schizophrenia, depression, and anxiety: (a) preconceived stereotypes, (b) a sense of personal responsibility or blame for the condition, and (c) perceptions of the patient's inability to recover from the condition. A stronger association between negative stereotypes and inability to recover was found with schizophrenia than depression or anxiety. Conversely, depression and anxiety were found to be correlated with personal responsibility or blame for the condition. The public perception of mental health conditions (e.g., depression, anxiety, schizophrenia) has a crucial role in deriving programs for reducing stigma and raising awareness. Personalized and efficacious treatment regimens may be facilitated by understanding these perceptions and the underlying explanations for why they exist.

Thailand, like all nations, has a responsibility to initiate environmental actions to preserve marine environments. Low- and middle-income countries face difficulties implementing feasible strategies to fulfill this ambitious goal. To contribute to the revitalization of Thailand's marine ecosystems, we investigated the level of tobacco product waste (TPW) on Thailand's public beaches. We conducted a cross-sectional observational survey at two popular public beaches. Research staff collected cigarette butts over two eight-hour days walking over a one-kilometer stretch of beach. We also compiled and analyzed data on butts collected from sieved sand at 11 popular beaches throughout Thailand's coast, with 10 samples of sieved sand collected per beach. Our survey at two beaches yielded 3067 butts in lounge areas, resulting in a mean butt density of 0.44/m². At the 11 beaches, sieved sand samples yielded butt densities ranging from 0.25 to 13.3/m², with a mean butt density of 2.26/m² (SD = 3.78). These densities show that TPW has become a serious problem along Thailand's coastline. Our findings are comparable with those in other countries. We report on government and civil society initiatives in Thailand that are beginning to address marine TPW. The solution will only happen when responsible parties, especially and primarily tobacco companies, undertake actions to eliminate TPW.

Our group has assembled a sample of 14,000 stars of spectral types B9-M9 with measured UVW Galactic space velocities and lying within 125 pc of Earth. We have identified candidate members of three nearby young (less than 100 Myr) moving groups. For stars of spectral types G5 and later, we have used the Kast spectrometer on the Shane 3m telescope at Lick Observatory to measure lithium abundance in order to determine stellar ages. With the data we have obtained from this run, we will be able to establish whether our candidates are bona fide members of the moving groups in question. I will be presenting the preliminary results from this survey, including spectra of the ~50 stars observed thus far. These nearby young stars will make excellent targets for direct imaging followup surveys, since any giant planets around young stars will still be warm, and will therefore be bright enough to detect with instruments like GPI.

Prediction of residual stresses and distortions due to laser beam welding of butt joints in pressure vessels

International Nuclear Information System (INIS)

Moraitis, G.A.; Labeas, G.N.

2009-01-01

A two-level three-dimensional Finite Element (FE) model has been developed to predict keyhole formation and thermo-mechanical response during Laser Beam Welding (LBW) of steel and aluminium pressure vessel or pipe butt-joints. A very detailed and localized (level-1) non-linear three-dimensional transient thermal model is initially developed, which simulates the mechanisms of keyhole formation, calculates the temperature distribution in the local weld area and predicts the keyhole size and shape. Subsequently, using a laser beam heat source model based on keyhole assumptions, a global (level-2) thermo-mechanical analysis of the LBW butt-joint is performed, from which the joint residual stresses and distortions are calculated. All the major physical phenomena associated to LBW, such as laser heat input via radiation, heat losses through convection and radiation, as well as latent heat are accounted for in the numerical model. Material properties and particularly enthalpy, which is very important due to significant material phase changes, are introduced as temperature-dependent functions. The main advantages of the developed model are its efficiency, flexibility and applicability to a wide range of LBW problems (e.g. welding for pressure vessel or pipework construction, welding of automotive, marine or aircraft components, etc). The model efficiency arises from the two-scale approach applied. Minimal or no experimental data are required for the keyhole size and shape computation by the level-1 model, while the thermo-mechanical response calculation by the level-2 model requires only process and material data. Therefore, it becomes possible to efficiently apply the developed simulation model to different material types and varying welding parameters (i.e. welding speed, heat source power, joint geometry, etc.) in order to control residual stresses and distortions within the welded structure

A Study on the Saving Method of Plate Jigs in Hull Block Butt Welding

Ko, Dae-Eun

2017-11-01

A large amount of plate jigs is used for alignment of welding line and control of welding deformations in hull block assembly stage. Besides material cost, the huge working man-hours required for working process of plate jigs is one of the obstacles in productivity growth of shipyard. In this study, analysis method was proposed to simulate the welding deformations of block butt joint with plate jigs setting. Using the proposed analysis method, an example simulation was performed for actual panel block joint to investigate the saving method of plate jigs. Results show that it is possible to achieve two objectives of quality accuracy of the hull block and saving the plate jig usage at the same time by deploying the plate jigs at the right places. And the proposed analysis method can be used in establishing guidelines for the proper use of plate jigs in block assembly stage.

Due to gendered inequalities in the division of domestic work, women with paid employment and family caregiving responsibilities can feel extremely tired with general distress and depression. Therefore, the purpose of this study was to examine the association between the number of family members and stress level by gender among Korean adults using a nationally representative dataset. We used a sample of 6,293 subjects aged 19 or older (3,629 female and 2,264 male) from the fifth Korea National Health and Nutrition Examination Survey. A multivariable logistic regression analysis with sociodemographic and health-related characteristics was conducted. Because there were gender differences, a stratified analysis was performed for each gender. Age, number of family members, education level, occupational status, depression, self-rated health status, and chronic diseases were found to have a significant association with stress level in the study subjects (pstress increased among females from family with two members (OR 1.521), three family members (OR 1.893), or four or more family members without spouse (OR 2.035) compared to those who live alone. We found that unmarried women are more likely to be stressed as the number of family members increases. Gender expectations giving women the main responsibility for domestic and care work may become a source of stress. Reconciliation of family and work remains women's responsibility in Korea. As family problems are recently becoming a big issue, our study shows the importance of considering gender difference in studies on stress according to family roles and functions.

Is a management degree worth the investment for physicians? A survey of members of the American College of Physician Executives.

Science.gov (United States)

Weeks, William B; Lazarus, Arthur; Wallace, Amy E

2008-01-01

In a survey of 568 physician members of the American College of Physician Executives (ACPE), most of whom had advanced management degrees (MBA, MMM, MPH), approximately 90% of respondents reported that their investment in the education was "worth it." The return on investment was independent of the quality of the academic institution, although primary care physicians stood to gain more relative to specialists. Salary comparisons showed that female physicians had approximately 20% lower incomes than male physicians, confirming the presence of a "glass ceiling" for female physician executives as seen in other medical specialties. These findings have implications for early and mid-career physicians and physician recruiters.

Thermo-mechanical FE-analysis of butt-welding of a Cu-Fe canister for spent nuclear fuel

International Nuclear Information System (INIS)

Josefson, B.L.; Karlsson, L.; Lindgren, L.E.; Jonsson, M.

1992-10-01

In the Swedish nuclear waste program it has been proposed that spent nuclear fuel shall be placed in composite copper-steel canisters. These canisters will be placed in holes in tunnels located some 500 m underground in a rock storage. The canisters consists of two cylinders of 4850 mm length, one inner cylinder made of steel and one outer cylinder made of copper. The outer diameter of the canister is 880 mm and the wall thickness for each cylinder is 50 mm. At the storage, the steel cylinder, which contains the spent nuclear fuel, is placed inside the copper cylinder. Thereafter, a copper end is butt welded to the copper cylinder using electron beam welding. To obtain penetration through the thickness with this weld method a backing ring is placed at the inside of the copper cylinder. In the present paper, the temperature, strain and stress fields present during welding and after cooling after welding are calculated numerically using the FE-code NIKE-2D. The aim is to use the results of the present calculations to estimate the risk for creep fracture during the subsequent design life. A large strain formulation is employed for the calculation of transient and residual stresses in the canister based on the calculated history of the temperature field present in the canister during the welding process. The contact algorithm available in NIKE-2D is used to detect possible contact between the steel and copper cylinders during the welding. To simplify the numerical calculations and reduce the computational time, rotational symmetry is assumed. For large gap distances between the steel and copper cylinders the residual stress field is calculated to have a shape similar to that observed in butt welded pipes with maximum axial stress values at the yield stress level. For small gap distances the backing ring will come in contact with the steel cylinder which leads to large residual stresses in the backing ring. The maximum accumulated plastic strain in the weld metal and

In sub-Saharan Africa, chronic kidney disease (CKD) is being recognized as a non-communicable disease (NCD) with high morbidity and mortality. In countries like Tanzania, people access many sources, including traditional medicines, to meet their healthcare needs for NCDs, but little is known about traditional medicine practices among people with CKD. Therefore, we sought to characterize these practices among community members with CKD in northern Tanzania. Between December 2013 and June 2014, we administered a previously-developed survey to a random sample of adult community-members from the Kilimanjaro Region; the survey was designed to measure traditional medicine practices such as types, frequencies, reasons, and modes. Participants were also tested for CKD, diabetes, hypertension, and HIV as part of the CKD-AFRiKA study. To identify traditional medicines used in the local treatment of kidney disease, we reviewed the qualitative sessions which had previously been conducted with key informants. We enrolled 481 adults of whom 57 (11.9 %) had CKD. The prevalence of traditional medicine use among adults with CKD was 70.3 % (95 % CI 50.0-84.9 %), and among those at risk for CKD (n = 147; 30.6 %), it was 49.0 % (95 % CI 33.1-65.0 %). Among adults with CKD, the prevalence of concurrent use of traditional medicine and biomedicine was 33.2 % (11.4-65.6 %). Symptomatic ailments (66.7 %; 95 % CI 17.3-54.3), malaria/febrile illnesses (64.0 %; 95 % CI 44.1-79.9), and chronic diseases (49.6 %; 95 % CI 28.6-70.6) were the most prevalent uses for traditional medicines. We identified five plant-based traditional medicines used for the treatment of kidney disease: Aloe vera, Commifora africana, Cymbopogon citrullus, Persea americana, and Zanthoxylum chalybeum. The prevalence of traditional medicine use is high among adults with and at risk for CKD in northern Tanzania where they use them for a variety of conditions including other NCDs. Additionally, many of these same people

Test usage surveys consistently find that sentence completion tests (SCTs) are among the most popular personality assessment instruments used by practitioners. What is not noted is which SCTs practitioners are using, why these tests are so popular, and whether practitioners are using formal scoring. We surveyed a random selection of 100 members of the Society for Personality Assessment. With a 60% return rate on a single mailing, we found that most psychologists who use incomplete sentence tests use the Rotter (1951) Incomplete Sentences Blank with children (18%), adolescents (32%), and adults (47%). Most practitioners said they do not read stems aloud and record answers themselves, and even fewer said they use formal scoring. The most common reasons for using an SCT are (a) to use it as part of an assessment battery (41 endorsements), (b) to determine personality structure (18 endorsements), and (c) to elicit quotable quotes (17 endorsements). Implications for practitioners and training suggestions for academicians who prepare future psychologists are noted.

Petrographic Analysis and Geochemical Source Correlation of Pigeon Peak, Sutter Buttes, CA

Science.gov (United States)

Novotny, N. M.; Hausback, B. P.

2013-12-01

The Sutter Buttes are a volcanic complex located in the center of the Great Valley north of Sacramento. They are comprised of numerous inter-intruding andesite and rhyolite lava domes of varying compositions surrounded by a shallow rampart of associated tephras. The Pigeon Peak block-and-ash flow sequence is located in the rampart and made up of a porphyritic Biotite bearing Hornblende Andesite. The andesite blocks demonstrate a high degree of propylization in hornblende crystals, highly zoned plagioclase, trace olivine, and display a red to gray color gradation. DAR is an andesite dome located less than one mile from Pigeon Peak. Of the 15 to 25 andesite lava domes within four miles from Pigeon Peak, only DAR displays trace olivine, red to grey color stratification, low biotite content, and propylitized hornblende. These characteristic similarities suggest that DAR may be the source for Pigeon Peak. My investigation used microprobe analysis of the DAR and Pigeon Peak feldspar crystals to identify the magmatic history of the magma body before emplacement. Correlation of the anorthite zoning within the feldspars from both locations support my hypothesis that DAR is the source of the Pigeon Peak block-and-ash flow.

Natural resource professionals have frequently criticized universities for poorly preparing graduates to succeed in their jobs. We surveyed members of the American Fisheries Society to determine which job skills and knowledge of academic topics employers, students, and university faculty members deemed most important to early-career success of fisheries professionals. Respondents also rated proficiency of recently hired, entry-level professionals (employers) on how well their programs prepared them for career success (students and faculty) in those same job skills and academic topics. Critical thinking and written and oral communication skills topped the list of important skills and academic topics. Employers perceived recent entry-level hires to be less well-prepared to succeed in their careers than either university faculty or students. Entry-level hires with post-graduate degrees rated higher in proficiency for highly important skills and knowledge than those with bachelor's degrees. We conclude that although universities have the primary responsibility for developing critical thinking and basic communication skills of students, employers have equal or greater responsibility for enhancing skills of employees in teamwork, field techniques, and communicating with stakeholders. The American Fisheries Society can significantly contribute to the preparation of young fisheries professionals by providing opportunities for continuing education and networking with peers at professional conferences.

The purpose of this study was to report in acute childhood idiopathic thrombocytopenic purpura (ITP) the current practices of French paediatric hematologists and to compare them to recent publications of American and British teams. A questionnaire was sent online to the members of the French Society of Pediatric Hematology/Immunology (SHIP). This questionnaire, adapted from a similar american study conducted in 2001, asked 16 questions based on the clinical presentation of a 5-year-old boy referred for an acute ITP. 59/123 SHIP members responded to the survey. In response to question regarding initial treatment, 86% of physicians would be given active treatments and only 9% would rarely or never administer any drug. When asked which agent would be used in case of treatment, 68% would choose to prescribe intravenous immunoglobulins and 32% corticosteroids, nobody recommended the use of anti-D immunoglobulins. Furthermore, 83% would usually hospitalize such a child. Finally, this study allowed us to update the current French management of treating pediatric ITP which is almost comparable among this subset of pediatric hematologists, but showed some discrepancies comparatively to the American and British studies.

Every member of the site can see all the data reported by every other member, view aggregated reports, identify “patients like them,” and learn about treatment options in order to live better with their condition. In previous studies, members reported benefits such as improved condition knowledge, increased medication adherence, and better management of side effects. However, the site evolved in 2011 from condition-specific “vertical” communities consisting only of people with the same disease to a “generalized platform,” in which every patient could connect with every other patient regardless of condition and with generic, rather than condition-specific, data tools. Some, but not all, communities received further custom tracking tools. Objective We aimed to understand (1) whether members of PatientsLikeMe using the generalized platform still reported similar benefits and (2) assess factors associated with benefits, such as community customization, site use, and patient activation. Methods A cross-sectional retrospective custom survey was fielded to 377,625 members between 2016 and 2017 including the Patient Activation Measure (PAM). A benefit index was developed for comparability across conditions. Results The invitation was viewed by 26,048 members of whom 11,915 did not respond, 5091 opted out, 1591 provided partial data, and 17 were screened out. Complete responses were received from 7434 participants. Users perceived greatest benefit in understanding how their condition may affect them (4530/6770, 66.91% participants, excluding “does not apply” answers), understanding what might help them live better with their condition (4247/6750, 62.92%), which treatments were available (4143/6898, 60.06%), understanding treatment side effects (4182/6902, 60.59%), and

INTRODUCTIONS AND AIMS: Research from western countries indicates that family members of addiction patients report heightened stress and psychological morbidity. This current study aimed to examine stress, coping behaviours, related morbidity and subsequent resource utilisation among family members of patients attending a national treatment program in Singapore. The study used a matched case-control design. One hundred family members of addiction patients attending treatment and 100 matched controls completed a semi-structured interview with a researcher. This included the Beck Depression Inventory-II, Short-Form Health Survey-36, General Health Questionnaire-28, Perceived Stress Scale, Family Member Impact Scale and Coping Questionnaire, and also assessed service utilisation. T-tests revealed significantly greater depression, stress and psychiatric morbidity and poorer overall well-being (Short-Form Health Survey-36) among family members compared with controls. Despite the apparent negative impact on mental health, their physical morbidity did not differ from controls and services utilisation was low. Tolerant-inactive coping was found to be most strongly correlated with psychological well-being. Multivariate analysis indicated that perceived stress was the strongest predictor of overall strain (General Health Questionnaire), but this was not moderated by coping style. Subjective appraisal of stress and coping responses are essential factors affecting the morbidity of family members. Family members demonstrated a need and willingness to engage in formal treatment/counselling for their own problems that were attributed to living with an addiction patient. This provides an opportunity for stress management and brief interventions to modify coping styles, thereby minimizing the potential negative mental health impact on family members. © 2011 Australasian Professional Society on Alcohol and other Drugs.

A national sample of 500 members of Gamblers Anonymous was surveyed by mail in order to gather information on suicidal history. One hundred sixty two usable surveys were returned representing 32.4% of the original sample. Compulsive gamblers who had a history of suicidal preoccupation began gambling at an earlier age than nonsuicidal gamblers and were more likely to have stolen to support their gambling. They also tended to have addicted relatives and children more than nonsuicidal gamblers did. The data suggest that those gamblers who had been suicidal tend to be more serious gamblers than nonsuicidal respondents.

Current international and national guidelines promote the use of emergency echocardiography in patients with cardiogenic shock. We assessed whether these recommendations are followed in clinical practice of infarct-related cardiogenic shock patients. For this purpose we conducted a web-based survey among all members of the German Society of Medical Intensive Care and Emergency Medicine (DGIIN); 40% of the DGIIN members completed the survey. Participants reported that in their department emergency echocardiography/ultrasound is performed on most patients in infarct-related cardiogenic shock presenting to the emergency department/chest pain unit or intensive care unit (58.6% versus 81.4%). Only 33% stated that on patients admitted directly to the catheterization laboratory emergency ultrasound/echocardiography is applied in their institution. Local availability of a standardized algorithm was lacking in the majority of departments (77.2%). A great proportion (38.3%) of participants stated that they personally had no formal training in emergency ultrasound. In order to meet the demands of the current guidelines, in addition to integration of ultrasound examinations into diagnostic algorithms, a structured training of all emergency and intensive care physicians is necessary.

In recent years, the number and scope of outsourced activities in the pharmaceutical industry have increased heavily. In addition, also the type of outsourcing has changed significantly in that time. This raises the question of whether and how sponsors retain the capability to select and to control the contract research organizations (CROs) involved and what expertise still has to be present in the development department as well as other relevant departments to ensure adequate oversight, also in line with the expectations of regulators and health authorities. In order to answer these questions, a survey was conducted among the German vfa member companies. The survey describes the latest developments and experiences in outsourcing by 18 German vfa member companies. It concentrates on measures how to implement Quality Assurance (QA) when performing outsourced clinical studies. This study shows that the majority of companies apply a full-outsourcing, preferred-provider model of clinical trial services, with the clinical research department playing the major role in this process. A large amount of guiding documents, processes and tools are used to ensure an adequate oversight of the services performed by the CRO(s). Finally the guiding principles for all oversight processes should be transparent communication, a clearly established expectation for quality, a precise definition of accountability and responsibility while avoiding silo mentality, and a comprehensive documentation of the oversight's evidence. For globally acting and outsourcing sponsors, oversight processes need to be aligned with regards to local and global perspectives. This survey shows that the current implementation of oversight processes in the participating companies covers all relevant areas to ensure highest quality and integrity of the data produced by the outsourced clinical trial.

The aim of this study was to explore family members' satisfaction with care and decision-making during the intensive care units stay and their follow-up needs after the patient's discharge or death. A cross-sectional survey study was conducted. Family members of patients recently treated in an ICU were participating. The questionnaire contented of background variables, the instrument Family Satisfaction in ICU (FS-ICU 24) and questions about follow-up needs. Descriptive and non-parametric statistics and a multiple linear regression were used in the analysis. A total of 123 (47%) relatives returned the questionnaire. Satisfaction with care was higher scored than satisfaction with decision-making. Follow- up needs after the ICU stay was reported by 19 (17%) of the participants. Gender and length of the ICU stay were shown as factors identified to predict follow-up needs.

Trade Union Cooperation in the EU: Views Among Swedish Trade Unions and Their Members

Directory of Open Access Journals (Sweden)

Bengt Furåker

2013-09-01

Full Text Available This article compares views among Swedish trade unions with those of their members regarding cross-national union cooperation in Europe or the EU. Data are derived from two different surveys, one among trade unions in 2010–2011 and the other among employees in 2006. It turns out that trade unions are generally more affirmative than their members to transnational union cooperation. In the employee survey, differences appear between members of the three peak-level organizations—the LO (manual workers, the TCO (white-collar workers, and Saco (professionals. However, controlling for education, these differences cannot be verified statistically. Higher education—which above all Saco members have—is linked to more positive attitudes toward transnational union cooperation. The gap between the organizations and their affiliates concerning engagement in European issues appears to be larger in the LO than in Saco, with the TCO somewhere in the middle.

To describe pharmacy faculty members' use of the online social network Facebook and compare the perspectives of faculty members with and without Facebook profiles regarding student/faculty relationships. An electronic survey instrument was sent to full-time faculty members (n = 183) at 4 colleges of pharmacy in Ohio seeking their opinions on student/faculty relationships on Facebook. If respondents answered "yes" to having a Facebook profile, they were asked 14 questions on aspects of being "friends" with students. If respondents answered "no," they were asked 4 questions. Of the 95 respondents (52%) to the survey instrument, 44 faculty members (46%) had a Facebook profile, while 51 faculty members (54%) did not. Those who had a profile had been faculty members for an average of 8.6 years, versus 11.4 years for those who did not have a Facebook profile. Seventy-nine percent of faculty members who used Facebook were not "friends" with their students. The majority of respondents reported that they would decline/ignore a "friend" request from a student, or decline until after the student graduated. Although a limited number of faculty members had used Facebook for online discussions, teaching purposes, or student organizations, the majority of universities did not have policies on the use of social networking sites. Online social network sites are used widely by students and faculty members, which may raise questions regarding professionalism and appropriate faculty/student relationships. Further research should address the student/preceptor relationship, other online social networking sites, and whether students are interested in using these sites within the classroom and/or professional organizations.

2017-06-01

At Indiana University School of Dentistry, a New Clinical Faculty Training (NCFT) program was created with the primary goals of informing new part-time faculty members of clinical policies and assessment guidelines and thus developing qualified and satisfied faculty members. The aim of this study was to determine if participation in the training program improved the participants' satisfaction and competence in comparison to their colleagues who did not participate in the program. Two cohorts were compared: a control group of part-time faculty members who did not receive formal training when they were hired (n=21; response rate 58.3%); and the intervention group, who had participated in the NCFT program (n=12; response rate 80%). A survey of faculty members in the control group gathered information on their experiences when initially hired, and a pretest was administered to measure their knowledge of clinical policies. After the control group was given an overview of the program, their feedback was collected through post surveys, and a posttest identical to the pretest was given that found statistically significant increases on questions one (p=0.003) and four (p=0.025). In February 2014, 15 new faculty members participated in the pilot implementation of the NCFT program. Of those 15, 12 (the intervention group) completed follow-up surveys identical to the pre survey used with the control group. Statistically significant differences were found for the factors clinical teaching (p=0.005) and assessment training (p=0.008) with better responses for the NCFT group. These results suggest that participation in the program was associated with improved clinical teaching knowledge and job satisfaction.

Full Text Available Cigarette butts are consistently the most collected items in litter clean-up efforts, which are a costly burden to local economies. In addition, tobacco waste may be detrimental to our natural environment. The tobacco industry has conducted or funded numerous studies on smokers’ littering knowledge and behavior, however, non-industry sponsored research is rare. We sought to examine whether demographics and smokers’ knowledge and beliefs toward cigarette waste as litter predicts littering behavior. Smokers aged 18 and older (n = 1,000 were interviewed about their knowledge and beliefs towards cigarette waste as litter. Respondents were members of the Research Now panel, an online panel of over three million respondents in the United States. Multivariate logistic regressions were conducted to determine factors significantly predictive of ever having littered cigarette butts or having littered cigarette butts within the past month (p-value < 0.05. The majority (74.1% of smokers reported having littered cigarette butts at least once in their life, by disposing of them on the ground or throwing them out of a car window. Over half (55.7% reported disposing of cigarette butts on the ground, in a sewer/gutter, or down a drain in the past month. Those who did not consider cigarette butts to be litter were over three and half times as likely to report having ever littered cigarette butts (OR = 3.68, 95%CI = 2.04, 6.66 and four times as likely to have littered cigarette butts in the past month (OR = 4.00, 95%CI = 2.53, 6.32. Males were significantly more likely to have littered cigarette butts in the past month compared to females (OR = 1.49, 95%CI = 1.14, 1.94. Holding the belief that cigarette butts are not litter was the only belief in this study that predicted ever or past-month littering of cigarette waste. Messages in anti-cigarette-litter campaigns should emphasize that cigarette butts are not just litter but are toxic

The psychological effect of alopecia areata (AA) is well documented, but group interaction may help lessen this burden. We aimed to determine factors that draw patients with AA and their families to group events. Surveys were administered at the annual alopecia areata bowling social in 2015 and 2016. This event is a unique opportunity for children with AA and their families to meet others with the disease and connect with local support group resources from the Minnesota branch of the National Alopecia Areata Foundation. Data from 2015 and 2016 were combined. Comparisons of subgroups were performed using Fisher exact tests for response frequencies and percentages and two-sample t tests for mean values. An equal number of men and women participated in the study (n = 13 each). The average age was 41.1 years. There were no significant differences (p > 0.05) in survey responses based on respondent age or sex. Twenty-three (88.5%) attendees sought to connect with others with AA and met three or more people during the event. Seventeen (65.4%) also attended other support group events. Twelve respondents (46.2%) came to support a friend or family member. One hundred percent of attendees identified socializing with others with AA as important. Group interaction is an important source of therapeutic support for people with AA and their families. © 2017 Wiley Periodicals, Inc.

Salt-impacted soils occur in floodplains, wetlands and backswamps in arid climates. These soils become sinks or temporary storage sites for soluble salts and contaminants including agricultural chemicals, industrial pollutants and radionuclides such as 129 I. The vertical distribution of I in the Black Butte soil series along the Virgin river was assessed and the distribution of I between I - , IO 3 - and organically bound I was determined. The speciation of I was compared to the organic C content, specific components of the organic C, and clay content. This study indicates that organic I was the most abundant form of I in these soil samples and that the content of organic I generally correlated to total organic matter and lignin (as measured by chemolysis) of the samples

2014-04-17

To explore the potential of tablet technology to address the specific workload challenges of pharmacy practice faculty members and to evaluate tablet usage after a department-wide iPad initiative. After conducting a needs assessment to determine pharmacy faculty attitudes towards tablet technology and to identify potential usage scenarios, all faculty members in a department of pharmacy practice received an iPad. After iPad distribution, training sessions and virtual tutorials were provided. An anonymous survey was administered to evaluate the pilot. The needs assessment survey revealed positive attitudes towards iPad technology, identified use scenarios, and led to a department-wide iPad pilot program. Most faculty members used iPads for connectivity with students (86%), paper/project annotation (68%), assessment (57%), and demonstration of tools used in practice (36%). For teaching, 61% of faculty members used iPads in seminars/laboratories, 57% used iPads in the experiential setting, and 43% used iPads in the classroom. Use of iPads for patient-care activities varied and depended on site support for mobile technology. The 23 faculty members with external practice sites used iPads to a greater extent and had more positive attitudes towards this technology compared with campus-based faculty members. Integration of tablet technology into the pharmacy education setting resulted in faculty-reported increased productivity and decreased paper waste. It also allowed faculty members to experiment with new teaching strategies in the classroom and experiential setting. Administrators at institutions exploring the use of tablet technology should allocate resources based on faculty needs and usage patterns.

This study is performed to check the three dimensional characteristics of residual stress in the dissimilar metal weld. Although two dimensional analysis has been widely used for the assessment of weld residual stress, it has limitations to understand the stress distribution of the third direction. 3-D analysis was done to understand residual stress distribution of the welded plate. A simple butt-welded plate was considered to show the stress variation on all direction. A mock-up plate weldment was fabricated with SA-508 and F316L, which are widely used in nuclear power plants. The analysis results were validated with the measured values in the mock-up.

This paper investigates the capability of linear thermal elastic numerical analysis to predict the welding distortion that occurs due to GMAW process. Distortion is considered as the major stumbling block that can adversely affect the dimensional accuracy and thus lead to expensive corrective work. Hence, forecast of distortion is crucially needed and ought to be determined in advance in order to minimize the negative effects, improve the quality of welded parts and finally to reduce the production costs. In this study, the welding deformation was simulated by using relatively new FEM software WELD PLANNER developed by ESI Group. This novel Welding Simulation Solution was employed to predict welding distortion induced in butt and T-joints with thickness of 4 mm. Low carbon steel material was used for the simulation and experimental study. A series of experiments using fully automated welding process were conducted for verification purpose to measure the distortion. By comparing between the simulation and experimental results, it was found out that this program code offered fast solution analysis time in estimating weld induced distortion within acceptable accuracy

IE Information No. 86-104: Unqualified butt splice connectors identified in qualified penetrations

International Nuclear Information System (INIS)

Jordan, E.L.

1992-01-01

During an NRC equipment qualification (EQ) inspection at Dresden Nuclear Power Station, May 19--23, 1986, a deficiency was discovered concerning a lack of similarity between tested and installed nylon insulated butt splices in EQ qualified GE electrical penetrations. commonwealth Edison sent four sample splices removed from Quad Cities Nuclear Power Station to Wyle Laboratory to further substantiate their qualification for use in a harsh environment. These splices were identical to those installed at Dresden. During the testing performed at Wyle Laboratory December 4--5, 1986, all four samples exhibited excessive leakage currents to ground when exposed to a steam environment. Commonwealth Edison consequently declared the splices unqualified and shut down its Quad Cities Unit 1 to rework the splices by wrapping them with previously qualified tape. Dresden Unit 2 has similarly reworked the splices by wrapping them with tape. Duane Arnold Energy Center also has commenced a shutdown in order to make repairs. The short circuits that occurred appeared to start by condensation entering the splice between the wire insulation and the nylon tubing. The arcing caused insulation degradation that then allowed arcs to pass through the insulation to the enclosure

To implement and evaluate a private Facebook group for members of a large Ontario multisite Family Health Team (FHT) to facilitate improved communication and collaboration. Program implementation and subsequent survey of team members. A large multisite FHT in Toronto, Ontario. Health professionals of the FHT. Usage patterns and self-reported perceptions of the Facebook group by team members. At the time of the evaluation survey, the Facebook group had 43 members (37.4% of all FHT members). Activity in the group was never high, and posts by team members who were not among the researchers were infrequent throughout the study period. The content of posts fell into two broad categories: 1) information that might be useful to various team members and 2) questions posed by team members that others might be able to answer. Of the 26 team members (22.6%) who completed the evaluation survey, many reported that they never logged into the Facebook page (16 respondents), and never used it to communicate with team members outside of their own site of practice (19 respondents). Only six respondents reported no concerns with using Facebook as a professional communication tool; the most frequent concerns were regarding personal and patient privacy. The use of social media by health care practitioners is becoming ubiquitous. However, the issues of privacy concerns and determining how to use social media without adding to provider workload must be addressed to make it a useful tool in health care.

Over half of general anesthetics in the UK involve supraglottic airway devices (SADs). The National Audit Project 4 undertaken by the Royal College of Anaesthetists demonstrated that aspiration was the most frequent complication relating to SAD use. SADs designed to reduce this risk (second-generation devices) are increasingly recommended in both adults and children. As well as routine use, SADs are recommended for use in cases of 'difficult airway'. This survey assessed current usage of SADs in routine practice and difficult airways. Sixteen questions, approved by the Association of Paediatric Anaesthetists of Great Britain and Ireland (APAGBI) survey committee, were distributed to all its members. Two hundred and forty-four members responded. Eighty-eight percent preferentially use first-generation rather than second-generation devices. The most important design feature was the availability of a complete range of sizes (84%). Seventy-seven percent felt that randomized controlled trials assessing SAD safety in children are needed. In cases of failed intubation, classically shaped SADs are preferred (79%). Three percent of responders intubate via an SAD routinely. Eighteen percent have employed this technique in an emergency. Thirty-six percent of responders have found an SAD to function poorly. Pediatric anesthesiologists appear slow to embrace second-generation SADs. The role of SADs in the management of difficult airways is widely accepted. Research currently has little influence over the choice of which SAD to use, which is more likely determined by personal choice and departmental preference. There is a risk that some SADs are unsafe. © 2013 John Wiley & Sons Ltd.

To quantify the effects of varying clinical communication styles (verbal and pictorial) on the ability of orthopaedic trauma surgeons in understanding an injury and formulate an initial management plan. A Research Electronic Data Capture survey was e-mailed to all OTA members. Respondents quantified (5-point Likert scale) how confident they felt understanding an injury and establishing an initial management plan based on the information provided for 5 common orthopaedic trauma scenarios. Three verbal descriptions were created for each scenario and categorized as limited, moderate, or detailed. The questions were repeated with the addition of a radiographic image and then repeated a third time including a clinical photograph. Statistical evaluation consisted of descriptive statistics and Kruskal-Wallis analyses using STATA (version 12.0). Of the 221 respondents, there were a total of 95 who completed the entire survey. Nearly all were currently taking call (92/95 = 96.8%) and the majority were fellowship trained (79/95 = 83.2%). Most practice at a level I trauma center (58/95 = 61.1%) and work with orthopaedic residents (62/95 = 65.3%). There was a significant increase in confidence scores between a limited, moderate, and detailed description in all clinical scenarios for understanding the injury and establishing an initial management plan (P 0.05). The addition of images in the form of radiographs and/or clinical photographs greatly improves the confidence of orthopaedic trauma surgeons in understanding injuries and establishing initial management plans with limited verbal information (P communicating providers.

This report describes the status of the Busted Butte Unsaturated Zone Transport Test (UZTT) and documents the progress of construction activities and site and laboratory characterization activities undertaken in fiscal year 1998. Also presented are predictive flow-and-transport simulations for Test Phases 1 and 2 of testing and the preliminary results and status of these test phases. Future anticipated results obtained from unsaturated-zone (UZ) transport testing in the Calico Hills Formation at Busted Butte are also discussed in view of their importance to performance assessment (PA) needs to build confidence in and reduce the uncertainty of site-scale flow-and-transport models and their abstractions for performance for license application. The principal objectives of the test are to address uncertainties associated with flow and transport in the UZ site-process models for Yucca Mountain, as identified by the PA working group in February 1997. These include but are not restricted to: (1) The effect of heterogeneities on flow and transport in unsaturated and partially saturated conditions in the Calico Hills Formation. In particular, the test aims to address issues relevant to fracture-matrix interactions and permeability contrast boundaries; (2) The migration behavior of colloids in fractured and unfractured Calico Hills rocks; (3) The validation through field testing of laboratory sorption experiments in unsaturated Calico Hills rocks; (4) The evaluation of the 3-D site-scale flow-and-transport process model (i.e., equivalent-continuum/dual-permeability/discrete-fracture-fault representations of flow and transport) used in the PA abstractions for license application; and (5) The effect of scaling from lab scale to field scale and site scale

Full Text Available This paper presents an empirical investigation to study the effects of institutional ownership, internal audit system, the number of non-executive board members and having differentiation between chair and general managers’ responsibilities on the likelihood of stock price crash on 110 listed firms on Tehran Stock Exchange over the period 2004-2011. The study uses Chen’ model (2001 [Chen, J., Hong, H., & Stein, J. C. (2001. Forecasting crashes: Trading volume, past returns, and conditional skewness in stock prices. Journal of Financial Economics, 61(3, 345-381.] to perform the investigation. Based on the results of the survey, there is a negative and meaningful relationship between stock price crash and institutional ownership when the level of significance is ten percent. In addition, as the number of non-executive board members increases, the chance of stock price crash decreases when the level of significance is five percent. However, separation between the responsibility of chair and general managers did not seem to influence on stock price and also having internal audit system had no impact on the likelihood of stock price change.

Salt-impacted soils occur in floodplains, wetlands and backswamps in arid climates. These soils become sinks or temporary storage sites for soluble salts and contaminants including agricultural chemicals, industrial pollutants and radionuclides such as {sup 129}I. The vertical distribution of I in the Black Butte soil series along the Virgin river was assessed and the distribution of I between I{sup -}, IO{sub 3}{sup -} and organically bound I was determined. The speciation of I was compared to the organic C content, specific components of the organic C, and clay content. This study indicates that organic I was the most abundant form of I in these soil samples and that the content of organic I generally correlated to total organic matter and lignin (as measured by chemolysis) of the samples.

Full Text Available The Joint United Nations Programme on HIV and AIDS (UNAIDS 90-90-90 targets have reinforced the importance of functioning laboratory services to ensure prompt diagnosis and to assess treatment efficacy. We surveyed the availability and utilization of technologies for HIV treatment monitoring and early infant diagnosis (EID in World Health Organization (WHO Member States.The survey questionnaire included 14 structured questions focusing on HIV testing, cluster of differentiation 4 (CD4 testing, HIV viral load (VL testing, and EID and was administered annually from 2012 to 2014 through WHO country offices, with each survey covering the previous 12-mo period. Across 127 targeted countries, survey response rates were 60% in 2012, 67% in 2013, and 78% in 2014. There were encouraging trends towards increased procurement of CD4 and VL/EID instruments in reporting countries. Globally, the capacity of available CD4 instruments was sufficient to meet the demand of all people living with HIV/AIDS (PLWHA, irrespective of treatment status (4.62 theoretical tests per PLWHA in 2013 [median 7.33; interquartile range (IQR 3.44-17.75; median absolute deviation (MAD 4.35]. The capacity of VL instruments was inadequate to cover all PLWHA in many reporting countries (0.44 tests per PLWHA in 2013 [median 0.90; IQR 0.30-2.40; MAD 0.74]. Of concern, only 13.7% of existing CD4 capacity (median 4.3%; IQR 1.1%-12.1%; MAD 3.8% and only 36.5% of existing VL capacity (median 9.4%; IQR 2.3%-28.9%; MAD 8.2% was being utilized across reporting countries in 2013. By the end of 2013, 7.4% of all CD4 instruments (5.8% CD4 conventional instruments and 11.0% of CD4 point of care [POC] and 10% of VL/EID instruments were reportedly not in use because of lack of reagents, the equipment not being installed or deployed, maintenance, and staff training requirements. Major limitations of this survey included under-reporting and/or incomplete reporting in some national programmes and

Goebel, L.; Bonten, C.

2014-05-01

The material development in the field of bioplastics is steadily increasing. It is important to examine the processability but the Investigation of further process steps is also very important. In this paper the weldability of bioplastics is discussed. Compounds of Polylactide (PLA) and Polybutyleneadipate-terephthalate (PBAT) are produced by a twin screw extruder with different mixing ratios. Tensile specimens are produced by injection moulding and the tensile tests are carried out. In order to verify the weldability, some tensile specimens are cut in halfes and butt welded. Afterwards a tensile test is performed with the welded samples and the results are compared with the values of the unwelded samples. For understanding the results, the morphology of the welds were examined and correlated. It has been found that blends with a mixing ratio of 50:50 have the lowest welding factor, because of the immiscibility of PLA and PBAT. Weld images show segregated areas that reduce the force transmission.

Full Text Available The 10 mm thick Aluminum 6061 plates have been corner joined using varied design and those were 45° Corner Butt and Corner Lap Joints (CB-45 & CL. Friction tool was hardened EMS 45. True experimental method was used with independent parameters is feed rate which varied at 10 mm/min, 15 mm/min and 30 mm/min respectively. Other parameter such as rotating speed was kept constant. Experiment results show that, CB-45 yields better properties than CL. The tensile strength of CB-45 reaches 163.7 MPa for 10 mm/min feed rate. Whilst CL produces joint with tensile strength equal 120 MPa for equal parameters. Microstructure observation showed that CB-45 produces fine and homogenous appearance of MgO compared to CL. This phenomenon is caused by the pin of CB-45 joint which fully penetrates the nugget zone which is not found in CL design. This microstructure in turn promotes higher tensile strength of CB-45.

The Dickinson Quadrangle, North Dakota, was evaluated to a depth of 1500 m to identify environments and delineate areas favorable for uranium deposits. Criteria used in the evaluation were developed for the National Uranium Resource Evaluation program. The evaluation primarily consisted of a surface study, subsurface investigation, and an in-house ground-water geochemical study. These studies were augumented by aerial radiometric and hydrogeochemical and stream-sediment studies. The evaluation results indicate that the Sentinel Butte and Tongue River Members of the Fort Union Formation have environments favorable for uraniferous lignite deposits. The Sentinel Butte, Tongue River, and Ludlow Members of the Fort Union Formation are favorable for sandstone uranium deposits. Environments unfavorable for uranium deposits are the remaining Cenozoic rocks and all the rocks of the Cretaceous

The objective of the survey was to describe the practices of clinical laboratories in terms of cultures in medical mycology. We have implemented this project within the members of the French Society for Medical Mycology (SFMM) to evaluate the analytical processes of the mycological examination in our laboratories. This preliminary study would help to suggest the future French guidelines. A questionnaire regarding the processing of mycology analysis was sent to the 227 members of the SFMM in 2009. The data involved 21 types of samples, direct microscopic examination with or without colouring and the reagents, the number of culture media, the types of media (Sabouraud, Sabouraud antibiotic, Sabouraud cycloheximide and chromogenic medium), temperature and duration of the incubation (days) and the existence of a first result before the end of the incubation period. The analytical processes were compared to an accredited laboratory according to EN ISO 15189. A great heterogeneity was observed in the 36 forms from 27 (75%) laboratories belonging to university hospitals among the 38 existing in France. As for deep samples, two microscopic exams were performed, only one was usually done. A more sensitive technique was preferred to the wet-mount for some samples. Routine samples are often inoculated on a chromogenic media. For deep samples two medium are inoculated (chromogenic media, Sabouraud and antibiotics). If the temperature of incubation is unique, 30°C was chosen. A temperature of 37°C was preferred for samples where Candida spp. is selected. When there are two temperatures of incubation, 27°C and 37°C were preferred. Each biologist can compare his proceedings to the other laboratories and to a laboratory already accredited. The question is to find the best strategies for each medical mycology specimen. They will aid the process of accreditation according to EN ISO 15189, which now applies in all laboratories in Europe.

Full Text Available On the occasion of CALA’s 40th anniversary in 2014, the 2013 Board of Directors appointed a Self-Assessment Task Force to conduct an assessment survey with special focuses on members’ awareness of CALA’s organizational structure and policies, its services to members, the extent of participation in events sponsored by CALA, and the level of satisfaction with CALA leadership. Although only one-fifth of the active members responded to the survey, the answers and feedback have identified areas for organizational improvement and have shown how active members view the current state of CALA. Some essential findings from the survey include: 1 the growth of overseas membership as a demographic trend, 2 a need to recruit student members, 3 a high percentage of CALA members not aware of CALA’s Mission/Vision/Goal, 4 conflicting data on CALA’s leadership, 5 discovery of low ratings (10-30% of respondents on eleven out of twelve rating questions, and 6 strong support for CALA as a representative organization of Chinese American librarians in North America. The findings of the survey will serve as a valuable reference for future strategic planning and for carrying out CALA’s long term goals.

AN INFRARED/X-RAY SURVEY FOR NEW MEMBERS OF THE TAURUS STAR-FORMING REGION

International Nuclear Information System (INIS)

Luhman, K. L.; Allen, P. R.; Mamajek, E. E.; Cruz, K. L.

2009-01-01

We present the results of a search for new members of the Taurus star-forming region using data from the Spitzer Space Telescope and the XMM-Newton Observatory. We have obtained optical and near-infrared spectra of 44 sources that exhibit red Spitzer colors that are indicative of stars with circumstellar disks and 51 candidate young stars that were identified by Scelsi and coworkers using XMM-Newton. We also performed spectroscopy on four possible companions to members of Taurus that were reported by Kraus and Hillenbrand. Through these spectra, we have demonstrated the youth and membership of 41 sources, 10 of which were independently confirmed as young stars by Scelsi and coworkers. Five of the new Taurus members are likely to be brown dwarfs based on their late spectral types (>M6). One of the brown dwarfs has a spectral type of L0, making it the first known L-type member of Taurus and the least massive known member of the region (M ∼ 4-7 M Jup ). Another brown dwarf exhibits a flat infrared spectral energy distribution, which indicates that it could be in the protostellar class I stage (star+disk+envelope). Upon inspection of archival images from various observatories, we find that one of the new young stars has a large edge-on disk (r = 2.''5 = 350 AU). The scattered light from this disk has undergone significant variability on a timescale of days in optical images from the Canada-France-Hawaii Telescope. Using the updated census of Taurus, we have measured the initial mass function for the fields observed by XMM-Newton. The resulting mass function is similar to previous ones that we have reported for Taurus, showing a surplus of stars at spectral types of K7-M1 (0.6-0.8 M sun ) relative to other nearby star-forming regions, such as IC 348, Chamaeleon I, and the Orion Nebula Cluster.

To examine faculty members' and students' use and perceptions of lecture recordings in a previously implemented lecture-capture initiative. Patterns of using lecture recordings were determined from software analytics, and surveys were conducted to determine awareness and usage, effect on attendance and other behaviors, and learning impact. Most students and faculty members were aware of and appreciated the recordings. Students' patterns of use changed as the novelty wore off. Students felt that the recordings enhanced their learning, improved their in-class engagement, and had little effect on their attendance. Faculty members saw little difference in students' grades or in-class engagement but noted increased absenteeism. Students made appropriate use of recordings to support their learning, but faculty members generally did not make active educational use of the recordings. Further investigation is needed to understand the effects of lecture recordings on attendance. Professional development activities for both students and faculty members would help maximize the learning benefits of the recordings.

We present a search for stellar members of young associations within 150 pc of the Sun, based on TGAS and an updated version of the BANYAN Σ software to determine Bayesian membership probabilities that includes Gaia–2MASS color-magnitude diagrams. We identify 32 new F0–M3-type bona fide members of the 10–200 Myr old Sco-Cen, Carina, Tucana-Horologium, Columba, and Octans associations and the AB Doradus, β Pictoris, and Carina-Near moving groups. These new bona fide members have measurements of their full kinematics and literature data consistent with a young age. We also confirm the membership of 66 previously known candidate members using their Gaia–Tycho trigonometric distances or new literature radial velocities, and identify 219 additional new candidate members, most of which do not yet have a radial velocity measurement. This work is the first step toward a completeness-corrected survey of young association members based on Gaia DR2 in the near future.

Spectral image analysis of the Hopi Buttes volcanic field, Arizona, U.S.A

Gabelman, J.W.; Wescott, T.F.

1987-01-01

The possibility of economic deposits, the semi-arid environment and the youth of applied remote-sensing technology suit the Hopi Buttes volcanic field as a test site for the application of multispectral image analysis to geologic interpretation and uranium evaluation. All possible enhancements of seasonal images were created in the General Electric interactive multispectral analyzer, model 100, and photographed for study. Contrast and directional edge-enhancement excellently delineated the patterns of megafractures and lineaments which are obscure to ground observation, but may control vent positions. Two sets of orthogonal groups of megafractures are oriented in the cardinal and diagonal directions; they suggest rotation of the stress ellipsoid, or the overlap of stresses from a differently oriented ellipsoid in a neighboring region. A megacircle of vents suggests a deep cylindrical fracture zone and possible incipient cauldron. Other circular areas with unusually abundant travertine maars or volcanic-material-free pipes suggest incipient collapse. Band ratios, density slices and histogram stretches selectively enhanced and differentiated stratigraphic formations, limburgite, tuff, travertine, gypsum-argillized rock and Fe-enriched rock. These were portrayed successfully on thematic map-images. A signature was derived for uraniferous travertine-marl and used to map its distribution. 30 refs.; 24 figs

2013-01-01

Objective To survey the Society for Vascular Surgery (SVS) membership with regard to practice trends related to work effort, employment status, practice ownership, endovascular cases, and anticipated changes in practice in the near future. Methods A survey questionnaire was developed to gather information about member demographics and practice, hours worked, full-time (FT) or part-time status, employment status, practice ownership, competition for referrals, proportion of endovascular vs open procedures, and anticipated changes in practice in the next 3 years. We used SurveyMonkey and distributed the survey to all active vascular surgeon (VS) members of the SVS. Results The response rate was 207 of 2230 (10.7%). Two thirds were in private practice, and 21% were in solo practice. Twenty-four percent were employed by hospitals/health systems. Those VS under the age of 50 years were more likely to exclusively practice vascular surgery compared with VS over the age of 50 years (P = .0003). Sixty-eight of the physicians (32.7%) were between 50 and 59 years old, 186 (90.3%) were men, 192 (92.8%) worked FT (>36 hours of patient care per week), and almost two thirds worked >60 hours per week. Those in physician-owned practices worked >40 hours of patient care per week more often than did FT employed VS (P = .012). Younger VS (age 50% of their workload being endovascular compared with older VS (age ≥50 years; P 40 hours of patient care per week than are FT employed VS. Longitudinal surveys of SVS members are imperative to help tailor educational, training, and practice management offerings, guide governmental activities, advocate for issues important to members, improve branding initiatives, and sponsor workforce analyses.

R. Sivasankari

2015-09-01

Full Text Available Magnetically impelled arc butt (MIAB welding is a pressure welding process used for joining of pipes and tubes with an external magnetic field affecting arc rotation along the tube circumference. In this work, MIAB welding of low alloy steel (T11 tubes were carried out to study the microstructural changes occurring in thermo-mechanically affected zone (TMAZ. To qualify the process for the welding applications where pressure could be up to 300 bar, the MIAB welds are studied with variations of arc current and arc rotation time. It is found that TMAZ shows higher hardness than that in base metal and displays higher weld tensile strength and ductility due to bainitic transformation. The effect of arc current on the weld interface is also detailed and is found to be defect free at higher values of arc currents. The results reveal that MIAB welded samples exhibits good structural property correlation for high pressure applications with an added benefit of enhanced productivity at lower cost. The study will enable the use of MIAB welding for high pressure applications in power and defence sectors.

2011-02-01

This paper presents work to identify factors affecting effectiveness of agri-business ventures (A-BVs) on the side of providers as perceived by their members. A survey was conducted among 95 members of A-BVs in Zanjan province, Iran. To collect data, a questionnaire was designed. Two distinct groups of A-BVs with low (group 1) and high (group 2) perceived (evaluated) levels of effectiveness were revealed. The study showed that there were significant differences between the two groups on important characteristics of A-BVs and their members. The study also found that there were statistically significant relationships between A-BVs' governance structure and capacity, management and organization characteristics and the perceived effectiveness, whereas there were no statistically significant relationships between A-BVs' advisory methods characteristic applied by members and the perceived effectiveness. Logistic regression results also showed that level of application of rules encouraging members' active participation in important decision makings, clear terms of reference to guide contracting procedures, roles, and responsibilities of parties involved, type of people served and geographical area of program coverage, and members' ability to use Information and Communication Technologies (ICTs) were predictors of the perceived (evaluated) effectiveness of A-BVs. The study showed that evaluation of members of effectiveness of A-BVs would not be the same. It is suggested that Iranian public agricultural extension organization, as responsible organization for monitoring and evaluating services conducted by A-BVs, considered these differences between members with different levels of some important variables. 2010 Elsevier Ltd.

2016-03-01

Full Text Available Objectives: Accidental hypothermia (AH is a potentially life-threatening condition that can lead to significant morbidity and life-long effects. Navy personnel are always at a greater risk of AH due to frequent outdoor work, wilderness exposure, prolonged immobility and exhaustion. The purpose of the survey was to assess Chinese Navy members’ awareness of AH and to make recommendations with regard to better measures for improving it. Methods: 111 Navy members completed a written questionnaire that was subsequently analyzed. Results: 30.6% of the respondents have experienced AH and 64.9% rated their knowledge of AH as “low” or “none”. Over half of them identified the initial symptom of AH as obvious shivering (69.4% and apathy (45.0%. As for the aggravate symptoms, 60.9% chose the wrong answer of more obvious shivering instead of the right one—absence of shivering (5.4%. In the case of the treatment of mild AH, more than half of the respondents chose the wrong answers. Conclusions: This study suggests that the basic skills of recognition and treatment of AH are inadequate in the Chinese Navy. Further work is required to develop a systematical, comprehensive and corresponding education method that would promote correct actions during AH.

We present two new late-type brown dwarf candidate members of the TW Hydrae association (TWA): 2MASS J12074836-3900043 and 2MASS J12474428-3816464, which were found as part of the BANYAN all-sky survey (BASS) for brown dwarf members of nearby young associations. We obtained near-infrared (NIR) spectroscopy for both objects (NIR spectral types are respectively L1 and M9), as well as optical spectroscopy for J1207-3900 (optical spectral type is L0γ), and show that both display clear signs of low gravity, and thus youth. We use the BANYAN II Bayesian inference tool to show that both objects are candidate members to TWA with a very low probability of being field contaminants, although the kinematics of J1247-3816 seem slightly at odds with that of other TWA members. J1207-3900 is currently the latest-type and the only isolated L-type candidate member of TWA. Measuring the distance and radial velocity of both objects is still required to claim them as bona fide members. Such late-type objects are predicted to have masses down to 11-15 M {sub Jup} at the age of TWA, which makes them compelling targets to study atmospheric properties in a regime similar to that of currently known imaged extrasolar planets.

To measure workers' attitudes towards and experiences of exposure to secondhand smoke (SHS) in the workplace. A stratified random sample of members from the Victorian Branch of the Australian Liquor, Hospitality and Miscellaneous Workers Union (LHMU) was interviewed by telephone in September 2001. Of the 1,078 respondents surveyed (77% response rate), hospitality workers comprised 49% of the sample, while the remainder comprised community services, property services and manufacturing workers. Overall, 54% of union members were employed in workplaces that did not completely ban smoking and 34% reported being exposed to SHS during their typical working day. Workplaces with total smoking bans had a high level of compliance with these restrictions, with no workers in these settings indicating exposure to SHS at work. Compared with other workers, hospitality workers reported working in environments that had more permissive smoking policies. Consistent with this, 56% of hospitality workers said they were exposed to SHS during a typical day at work compared with 11% of other workers. Overall, 79% of workers expressed concern about exposure to SHS, including 66% of smokers. Compared with other workers, hospitality workers reported a higher level of concern about exposure to SHS at work. These findings provide evidence that many workers, and especially those employed in the hospitality sector, are exposed to SHS during their working day and are concerned about the effects of such exposure on their health. These findings indicate that workplace smoke-free policies are effective in reducing worker exposure to SHS and demonstrate support for the extension of smoke-free policies to hospitality workplaces.

Due to recent legislations on euthanasia and its current practice in the Netherlands and Belgium, issues of end-of-life medicine have become very vital in many European countries. In 2002, the Ethics Working Group of the German Association for Palliative Medicine (DGP) has conducted a survey among its physician members in order to evaluate their attitudes towards different end-of-life medical practices, such as euthanasia (EUT), physician-assisted suicide (PAS), and terminal sedation (TS). An anonymous questionnaire was sent to the 411 DGP physicians, consisting of 14 multiple choice questions on positions that might be adopted in different hypothetical scenarios on situations of "intolerable suffering" in end-of-life care. For the sake of clarification, several definitions and legal judgements of different terms used in the German debate on premature termination of life were included. For statistical analysis t-tests and Pearson-correlations were used. The response rate was 61% (n = 251). The proportions of the respondents who were opposed to legalizing different forms of premature termination of life were: 90% opposed to EUT, 75% to PAS, 94% to PAS for psychiatric patients. Terminal sedation was accepted by 94% of the members. The main decisional bases drawn on for the answers were personal ethical values, professional experience with palliative care, knowledge of alternative approaches, knowledge of ethical guidelines and of the national legal frame. In sharp contrast to similar surveys conducted in other countries, only a minority of 9.6% of the DGP physicians supported the legalization of EUT. The misuse of medical knowledge for inhumane killing in the Nazi period did not play a relevant role for the respondents' negative attitude towards EUT. Palliative care needs to be stronger established and promoted within the German health care system in order to improve the quality of end-of-life situations which subsequently is expected to lead to decreasing requests

Establishment of the Canadian Institutes of Health Research (CIHR) in 2000 resulted in increased funding for health research in Canada. Since 2001, the number of proposals submitted to CIHR that, following peer review, are judged to be of scientific merit to warrant funding, has grown by 77%. But many of these proposals do not receive funding because of budget constraints. Given the role of Members of Parliament in setting government funding priorities, we surveyed Members of Parliament about their knowledge of and attitudes toward health research, health research funding and CIHR. All Members of Parliament were invited to participate, or to designate a senior aide to participate, in a 15-minute survey of knowledge of and attitudes toward health research, health research funding and CIHR. Interviews were conducted between July 15, 2006, and Dec. 20, 2006. Responses were analyzed by party affiliation, region and years of service as a Member of Parliament. A total of 101 of 308 Members of Parliament or their designated senior aides participated in the survey. Almost one-third of respondents were senior aides. Most of the respondents (84%) were aware of CIHR, but 32% knew nothing about its role. Participants believed that health research is a critical component of a strong health care system and that it is underfunded. Overall, 78% felt that the percentage of total government spending directed to health research funding was too low; 85% felt the same way about the percentage of government health care spending directed to health research. Fifty-four percent believed that the federal government should provide both funding and guidelines for health research, and 66% believed that the business sector should be the primary source of health research funding. Participants (57%) most frequently defined health research as study into cures or treatments of disease, and 22% of participants were aware that CIHR is the main federal government funding organization for health

Anger toward God is a common form of spiritual struggle, one that people often experience when they see God as responsible for severe harm or suffering. The aim of this study was to assess the prevalence, correlates, and preferred coping strategies associated with anger toward God among family members of hospice patients. Teams from a large hospice in the midwestern United States distributed surveys, one per household, to family members of home-care patients. The survey assessed feelings toward God (anger/disappointment and positive feelings), depressive symptoms, religiosity, and perceived meaning. Participants also rated their interest in various strategies for coping with conflicts with God. Surveys (n=134) indicated that 43% of participants reported anger/disappointment toward God, albeit usually at low levels of intensity. Anger toward God was associated with more depressive symptoms, lower religiosity, more difficulty finding meaning, and belief that the patient was experiencing greater pain. Prayer was the most highly endorsed strategy for managing conflicts with God. Other commonly endorsed strategies included reading sacred texts; handling the feelings on one's own; and conversations with friends, family, clergy, or hospice staff. Self-help resources and therapy were less popular options. Anger toward God is an important spiritual issue among family members of hospice patients, one that is commonly experienced and linked with depressive symptoms. It is valuable for hospice staff to be informed about the issue of anger toward God, especially because many family members reported interest in talking with hospice team members about such conflicts.

Butt-fusion welding process is used to join the polymeric pipes. Recently, some researchers suggest the curved surface to enhance a welding quality. We investigated how curved welding surface affects heat and flow behaviors of polymer melt during the process in 2D axisymmetric domain with finite element method, and discussed the effect to the welding quality. In this study, we considered HDPE pipes. In heat soak stage, curved phase interface between the melt and solid is shown along the shape of welding surface. In jointing stage, squeezing flow is generated between curved welding surface and phase interface. The low shear rate in fusion domain reduces the alignment of polymer to the perpendicular direction of pipes, and then this phenomenon is expected to help to enhance the welding quality.

Full Text Available Background: Achieving high participation of communities representative of all sub-populations is needed in order to ensure broad applicability of biobank study findings. This study aimed to understand potentially mutable attitudes and opinions commonly correlated with biobank participation in order to inform approaches to promote participation in biobanks. Methods: Adults from two University of Maryland (UMD Faculty Physicians, Inc. outpatient practices were invited to watch a video and complete a survey about a new biobank initiative. We used: Chi-square to assess the relationship between willingness to join the biobank and participant characteristics, other potentially mutable attitudes and opinions, and trust in the UMD. We also used t-test to assess the relationship with trust in medical research. We also prioritize proposed actions to improve attitudes and opinions about joining biobanks according to perceived responsiveness. Results: 169 participants completed the study, 51% of whom indicated a willingness to join the biobank. Willingness to join the biobank was not associated with age, gender, race, or education but was associated with respondent comfort sharing samples and clinical information, concerns related to confidentiality, potential for misuse of information, trust in UMD, and perceived health benefit. In ranked order, potential actions we surveyed that might alleviate some of these concerns include: increase chances to learn more about the biobank, increase opportunities to be updated, striving to put community concerns first, including involving community members as leaders of biobank research, and involving community members in decision making. Conclusions: This study identified several attitudes and opinions that influence decisions to join a biobank, including many concerns that could potentially be addressed by engaging community members. We also demonstrate our method of prioritizing ways to improve attitudes and opinions

Autogenous Tungsten Inert Gas (TIG) welding has been conducted on aluminum alloy A1100. The purpose of this research is to determine the proper current and speed of autogenous TIG welding with butt joint pattern. Variations on welding current are 150 A, 155 A, and 160 A with the variations on welding speed are 1 mm/seconds, 1.1 mm/seconds, 1.2 mm/seconds. The welded results were tested using non-destructive test (NDT) method using X-Ray radiography. After the test, it is found that the appropriate current for the best result without porosity can be achieved using the welding parameter of welding current of 160 A and the welding speed of 1.1 mm seconds.

Design: Program implementation and subsequent survey of team members. Setting: A large multisite FHT in Toronto, Ontario. Participants: Health professionals of the FHT. Main outcome measures: Usage patterns and self-reported perceptions of the Facebook group by team members. Results: At the time of the evaluation survey, the Facebook group had 43 members (37.4% of all FHT members. Activity in the group was never high, and posts by team members who were not among the researchers were infrequent throughout the study period. The content of posts fell into two broad categories: 1 information that might be useful to various team members and 2 questions posed by team members that others might be able to answer. Of the 26 team members (22.6% who completed the evaluation survey, many reported that they never logged into the Facebook page (16 respondents, and never used it to communicate with team members outside of their own site of practice (19 respondents. Only six respondents reported no concerns with using Facebook as a professional communication tool; the most frequent concerns were regarding personal and patient privacy. Conclusion: The use of social media by health care practitioners is becoming ubiquitous. However, the issues of privacy concerns and determining how to use social media without adding to provider workload must be addressed to make it a useful tool in health care.

As a continuing effort to enhance the quality of palliative care for the dying, this study examined (1) the prevalence of spirituality among hospice interdisciplinary team (IDT) members; (2) whether spirituality is related to job satisfaction; and (3) the structural path relationships among four variables: spiritual belief, integration of spirituality at work, self actualization and job satisfaction. The study surveyed 215 hospice IDT members who completed the Jarel Spiritual Well-Being Scale, the Chamiec-Case Spirituality Integration and Job Satisfaction Scales. Multiple regression and structural path modeling methods were applied to explain the path relationships involving all four variables. The IDT members surveyed were: nurses, 46.4%; home health aids, 24.9%; social workers, 17.4%; chaplains, 4.2%; physicians, 2.3%; and other, 4.8%. Ninety-eight percent of the respondents viewed themselves as having spiritual well-being. On a 0-100 scale, IDT staff reported high spiritual belief (mean = 89.4) and they were self-actualizing (mean = 82.6). Most reported high job satisfaction (mean = 79.3) and spiritual integration (mean = 67.9). In multiple regression, spirituality, integration and self-actualization explained 22% of the variation in job satisfaction (R = 0.48; adjusted R(2) = 0.218; df = 3,175; F = 17.2; p = 0.001). Structural path models revealed that job satisfaction is more likely to be realized by a model that transforms one's spirituality into processes of integrating spirituality at work and self actualization (chi(2) = 0.614; df = 1; p = 0.433) than a model that establishes a direct path from spirituality to job satisfaction (chi(2) = 1.65; df = 1; p = 0.199). Hospice IDT member's integration of their spirituality at work and greater self actualization significantly improve job satisfaction.

Food banks provide supplemental food to low-income households, yet little is known about the cardiovascular health of food banks members. This study therefore described cardiovascular disease (CVD) risk factors among food bank members and explored associations between food insecurity and CVD risk. Adults ≥18 years (n = 77) from three food bank sites in metro Vancouver, British Columbia completed surveys and physical assessments examining a range of socio-demographic variables and CVD risk factors. A composite measure of myocardial infarction (MI) risk called the INTERHEART score was assessed and household food insecurity was measured using the Household Food Security Survey Module. Regression models were used to explore associations between food insecurity and CVD risk measures, including the INTERHEART score. Ninety-seven percent of food bank members reported experiencing food insecurity, 65% were current smokers, 53% reported either chronic or several periods of stress in the past year, 55% reported low physical activity levels and 80% reported consuming fewer than five servings of fruit and vegetables daily. Prevalence of self-reported diabetes and hypertension were 13% and 29% respectively. Fifty-two percent of the sample were at high risk of non-fatal MI. No statistically significant associations were found between increased severity of food insecurity and CVD risk factors among this sample where both severe food insecurity and high CVD risks were prevalent. Food bank members were at elevated risk for CVD compared with the general population. Strategies are needed to reduce prevalence of food insecurity and CVD risk factors, both of which disproportionately affected food bank members.

We developed a hospital-based cardiopulmonary resuscitation (CPR) training model focused on the target population (family members of patients with potential risks for cardiac arrest) and compared the outcome of CPR training between target and non-target populations for validity. Family members of patients in training were divided into three groups on the basis of patients' diseases, as follows: 1) the cardio-specific (CS) risk group, including family members of patients with cardiac disease at risk of cardiac arrest; 2) the cardiovascular (CV) risk group, including family members of patients with risk factors for cardiovascular disease; and 3) the no-risk group. Pre- and posttraining surveys and skill tests as well as a post-training 3-month telephone survey were conducted. Educational outcomes were analyzed. A total of 203 family members were enrolled into 21 CPR training classes. The CS group (n=88) included elderly persons and housewives with a lower level of education compared with the CV (n=79) and no-risk groups (n=36). The CS group was motivated by healthcare professionals and participated in the training course. The CS, CV, and no-risk groups showed improvements in knowledge, willingness to perform CPR, and skills. Despite the older age and lower level of education in the CS group, the effects of education were similar to those in the other groups. A high rate of response and secondary propagation of CPR training were observed in the CS group. Family members of patients with heart disease could be an appropriate target population for CPR training, particularly in terms of recruitment and secondary propagation. Targeted intervention may be an effective training strategy to improve bystander CPR rates.

Whalen, Mathilde Logan; Loper, Ann Booker

2014-03-01

This study examines the association between the incarceration of a household member and adolescent pregnancy, and evaluates whether this association extends beyond that of other variables associated with sexual health. We used data from 12 waves of the National Longitudinal Survey of Youth: Child and Young Adult. After eliminating males and individuals who did not respond to key questions, a sample of 1,229 girls (ages 14-19) was analyzed. Girls who experienced the incarceration of a household member faced more demographic and family environment risk factors than those who did not. Regression analyses demonstrated that the addition of a household incarceration variable afforded superior prediction of teenage pregnancy relative to the prediction based on demographic and family features alone. Programs that are directed toward reducing teen pregnancy will benefit from attention to the home situation of the at-risk girl, particularly the experience of household member incarceration and related family dynamics.

Do patient surveys work? The influence of a national survey programme on local quality-improvement initiatives.

2008-12-01

To assess current attitudes towards the national patient survey programme in England, establish the extent to which survey results are used and identify barriers and incentives for using them. Qualitative interviews with hospital staff responsible for implementing the patient surveys (survey leads). National Health Service (NHS) hospital organisations (trusts) in England. Twenty-four patient survey leads for NHS trusts. Perceptions of the patient surveys were mainly positive and were reported to be improving. Interviewees welcomed the surveys' regular repetition and thought the questionnaires, survey methods and reporting of results, particularly inter-organisational benchmark charts, were of a good standard. The survey results were widely used in action planning and were thought to support organisational patient-centredness. There was variation in the extent to which trusts disseminated survey findings to patients, the public, staff and their board members. The most common barrier to using results was difficulty engaging clinicians because survey findings were not sufficiently specific to specialties, departments or wards. Limited statistical expertise and concerns that the surveys only covered a short time frame also contributed to some scepticism. Other perceived barriers included a lack of knowledge of effective interventions, and limited time and resources. Actual and potential incentives for using survey findings included giving the results higher weightings in the performance management system, financial targets, Payment by Results (PbR), Patient Choice, a patient-centred culture, leadership by senior members of the organisation, and boosting staff morale by disseminating positive survey findings. The national patient surveys are viewed positively, their repetition being an important factor in their success. The results could be used more effectively if they were more specific to smaller units.

The aim of the present study was to investigate whether job satisfaction mediates between leader-member exchange and nurse turnover intentions. Limited knowledge is available on the mediating role of job satisfaction between leader-member exchange and turnover intentions in the nursing field. This is a cross-sectional survey study. Data were collected in a US hospital. Higher leader-member exchange was associated with lower turnover intentions (β=-0.41, PLeader-member exchange was positively related to one's job satisfaction (β=0.50, Pleader-member exchange and job satisfaction were both controlled for, the link between leader-member exchange and turnover intentions was no longer significant (β=-0.12, P>0.05). Job satisfaction mediates the link between leader-member exchange and turnover intentions. The present study reinforces the significant role of managers. Nurse managers can try to cultivate a good relationship with the nurses. This can enhance nurses' job satisfaction and in turn lower their turnover intentions. © 2010 The Authors.

Field performance of wood-burning and coal-burning appliances in Crested Butte during the 1989-90 heating season. Final report

International Nuclear Information System (INIS)

Jaasma, D.R.; Champion, M.R.; Gundappa, M.

1991-10-01

The field performance of woodburning and coalburning appliances in and around Crested Butte, CO, has been evaluated. Measurements included particulate matter (PM), carbon monoxide (CO), and weekly average burn rates. Woodburning appliances included conventional airtight stoves, EPA-certified catalytic stoves, and EPA-certified noncatalytic stoves. Compared to the emissions measured from conventional stoves, the certified stoves reduced PM emission factors (g/kg) by 53% and CO emission factors by 49%. Coalburning appliances included a commercial scale boiler, a residential stoker, and hand-fired coalstove. The coalburning appliances were compared to conventional woodstoves on a grams of pollutant per joule of heat output basis. The automatically stoked coal appliances reduced PM and CO emissions by roughly 84% and 85%, respectively. The hand-fired stove was cleaner than expected, reducing PM by 55% and CO by 27%

Feasibility evaluations for the integration of laser butt welding of tubes in industrial pipe coil production lines

Penasa, Mauro; Colombo, Enrico; Giolfo, Mauro

1994-09-01

Due to the good performance shown by laser welded joints, to the quality and repeatability achievable by this welding technique and to its high process productivity, a feature inherent to the laser technology which, together with its high flexibility, allows different operations to be performed by a single source, consistent savings in a production line may be obtained. Therefore laser welding techniques may be of high relevance for industrial applications, provided that a sufficient attention is paid to avoiding a low utilization time to the operating laser source. The paper describes a feasibility study for the integration of a laser source as an automatic unit for circumferential butt welding of tubes in production lines of pipe coils, just before the cold bending station. Using a 6 kW CO2 source, thickness ranging from 3.5 to 11.2 mm in carbon, low alloyed Cr-Mo and austenitic stainless steels, have been successfully welded. Cr-Mo steels require on line preheating treatment, which however can be achieved by laser defocused passes just before welding. The results of the preliminary qualification performed on laser welded joints of the involved topologies of product (materials, diameters and thicknesses) are described together with technological tests required for approval: laser circumferential butt welding of tubes has proven to be effective, with satisfactory and repeatable results and good joint performances. An exhaustive comparison with current welding techniques (TIG, MIG) is then carried out, along with a detailed analysis of the potential advantages and benefits which may be expected by using the laser welding technique, as well as with a first estimation of the investments and running costs. Since laser productivity is saturated only at a rough 35% during the year, an accurate analysis of other possible applications and of a possible lay out of a laser working cell integrated in the factory production lines is performed. Usually little attention is

To gather and evaluate the perceptions of students, faculty members, and administrators regarding the frequency and appropriateness of classroom technology use. Third-year pharmacy students and faculty members at 6 colleges and schools of pharmacy were surveyed to assess their perceptions about the type, frequency, and appropriateness of using technology in the classroom. Upper-level administrators and information technology professionals were also interviewed to ascertain overall technology goals and identify criteria used to adopt new classroom technologies. Four hundred sixty-six students, 124 faculty members, and 12 administrators participated in the survey. The most frequently used and valued types of classroom technology were course management systems, audience response systems, and lecture capture. Faculty members and students agreed that faculty members appropriately used course management systems and audience response systems. Compared with their counterparts, tech-savvy, and male students reported significantly greater preference for increased use of classroom technology. Eighty-six percent of faculty members reported having changed their teaching methodologies to meet student needs, and 91% of the students agreed that the use of technology met their needs. Pharmacy colleges and schools use a variety of technologies in their teaching methods, which have evolved to meet the needs of the current generation of students. Students are satisfied with the appropriateness of technology, but many exhibit preferences for even greater use of technology in the classroom.

This study aimed to identify and compare predictors of job satisfaction between instructional and clinical faculty members. A 61-item faculty job satisfaction survey was distributed to 1898 academic faculty members at the University of Michigan Medical School. The anonymous survey was web-based. Questions covered topics on departmental organisation, research, clinical and teaching support, compensation, mentorship, and promotion. Levels of satisfaction were contrasted between faculty members on the two tracks, and predictors of job satisfaction were identified using linear regression models. Response rates for the instructional and clinical faculty groups were 43.1% and 46.7%, respectively. Clinical faculty members reported being less satisfied with how they were mentored and fewer reported understanding the process for promotion. There was no significant difference in overall job satisfaction between the two faculty groups. Surprisingly, clinical faculty members with mentors were significantly less satisfied with how they were mentored and with career advancement, and were significantly less likely to choose an academic career if they had to do it all over again compared with instructional faculty mentees. Additionally, senior-level clinical faculty members were significantly less satisfied with their opportunities to mentor junior faculty members compared with senior-level instructional faculty staff. Significant predictors of job satisfaction for both groups included areas of autonomy, meeting career expectations, work-life balance, and departmental leadership. In the clinical track only, compensation and career advancement variables also emerged as significant predictors of overall job satisfaction. Greater emphasis must be placed on faculty members' well-being at both the institutional level and the level of departmental leadership. Efforts to enhance job satisfaction and improve retention are more likely to succeed if they are directed by locally designed

Smoking cessation following lung cancer diagnosis has been found to improve several patient outcomes. Electronic cigarette (e-cigarette) use is now prevalent within Great Britain, however, use and practice among patients with lung cancer has not as yet been explored. The current study aims to explore e-cigarette use among patients and examine current practice among clinicians. The results have important implications for future policy and practice. Members of The British Thoracic Oncology Group (BTOG) were contacted via several e-circulations (N = 2,009), requesting them to complete an online survey. Of these, 7.7 % (N = 154) completed the survey, which explored participant demographics and smoking history, perceptions of patient e-cigarette use, practitioner knowledge regarding sources of guidance pertaining to e-cigarettes, and practitioner advice. Practitioners frequently observed e-cigarette use among patients with lung cancer. The majority of practitioners (81.4 %) reported responding to patient queries pertaining to e-cigarettes within the past year; however, far fewer (21.0 %) felt confident providing patients with e-cigarette advice. Practitioner confidence was found to differentiate by gender (p = 0.012) and employment speciality (p = 0.030), with nurses reporting particularly low levels of confidence in advising. The results also demonstrate extensive variability regarding the practitioner advice content. The results demonstrate that patients refer to practitioners as a source of e-cigarette guidance, yet few practitioners feel confident advising. The absence of evidence-based guidance may have contributed towards the exhibited inconsistencies in practitioner advice. The findings highlight that training should be delivered to equip practitioners with the knowledge and confidence to advise patients effectively; this could subsequently improve smoking cessation rates and patient outcomes.

2015-11-01

Full Text Available In despite of extensive research of franchising in the scientific community, there are a lot of unresolved issues relating to franchising, in particular its regulation at the national level and at the level of the European Union that is why the purpose of the paper is to summarise and present the difference between state regulation of franchising in the EU member states and to research the basic principles of state regulation of franchising in the EU also to analyze legislation of the franchise relationship. Methodology. The survey is based on a comparison of data from all EU member countries and analisis of the legal framework of each country in particular and in general EU legislation. The article is devoted to a detailed analysis of main features of the franchise business in Europe. The mechanism of implementation of franchise relations between EU member states are studied. Government regulation of franchising in the EU member states are investigated. The rate of growth of franchising in Europe are analized. Results. By comparing different state laws and regulations of franchising we have identified the most effective and productive. We divided counties into two groups due to their regulation of franchising: countries which do not have a special government regulation of franchising; the countries which have state regulation of franchising; countries which have government regulation of franchising and it is governed by EU law, countries in which regulation is carried out in accordance with EU law. Thus, results of the survey showed that government regulation of franchising, as well as its regulation at the level of EU institutions have a positive impact on the development of franchising relationships. Practical implications of the results of the paper will help to develop well known network of franchise bussiness without legislative interference. Value/originality. It is first time we have grouped countries due to the main aspects of state

Modern military missions place numerous demands on service members, including tactical, personal, and cultural challenges. The purpose of this study was to explore how domains of multicultural personality (cultural empathy, open-mindedness, social initiative, emotional stability, and flexibility) and combat exposure relate to posttraumatic stress disorder (PTSD) in service members. Participants (N = 163) completed the Multicultural Personality Questionnaire, Combat Exposure Scale, and PTSD Checklist-Military as part of an online survey. The majority of participants were Caucasian (87%), mean age was 33 years, and all were deployed at least once to Iraq or Afghanistan Regression results indicated that higher levels of combat exposure and open-mindedness and lower levels of flexibility and emotional stability were significant predictors of higher PTSD severity. The interactions between combat exposure and flexibility and combat exposure and openness were also significant. Higher levels of flexibility and emotional stability seem particularly important in their association with lower PTSD severity for service members. © 2014 Wiley Periodicals, Inc.

Approval of the research proposal by an ethical review committee from both sponsoring and host countries is a generally agreed requirement in externally sponsored research.However, capacity for ethics review is not universal. Aim of this study was to identify opinions and views of the members serving in ethical review and ethics committees in Sri Lanka on informed consent, essential components in the information leaflet and the consent form. We obtained ethical approval from UK and Sri Lanka. A series of consensus generation meetings on the protocol were conducted. A task oriented interview guide was developed. The interview was based on open-ended questionnaire. Then the participants were given a WHO checklist on informed consent and requested to rate the items on a three point scale ranging from extremely important to not important. Twenty-nine members from ethics committees participated. Majority of participants (23), believed a copy of the information leaflet and consent form, should accompany research proposal. Opinions about the items that should be included in the information leaflets varied. Participants identified 18 criteria as requirements in the information leaflet and 19 for the consent form. The majority, 20 (69%), believed that all research need ethical approval but identified limited human resource, time and inadequate capacity as constraints. Fifteen (52%) believed that written consent is not required for all research. Verbal consent emerged as an alternative to written consent. The majority of participants rated all components of the WHO checklist as important. The number of themes generated for the consent form (N = 18) is as many as for the information leaflet (N = 19) and had several overlaps. This suggests that the consent form should be itemized to reflect the contents covered in the information leaflet. The participants' opinion on components of the information leaflets and consent forms proved to be similar with WHO checklist on informed

We have compiled photometry at 3.4, 4.6, 12, and 22 μm from the all-sky survey performed by the Wide-field Infrared Survey Explorer (WISE) for all known members of the Taurus complex of dark clouds. Using these data and photometry from the Spitzer Space Telescope, we have identified members with infrared excess emission from circumstellar disks and have estimated the evolutionary stages of the detected disks, which include 31 new full disks and 16 new candidate transitional, evolved, evolved transitional, and debris disks. We have also used the WISE All-Sky Source Catalog to search for new disk-bearing members of Taurus based on their red infrared colors. Through optical and near-infrared spectroscopy, we have confirmed 26 new members with spectral types of M1-M7. The census of disk-bearing stars in Taurus should now be largely complete for spectral types earlier than ∼M8 (M ≳ 0.03 M ☉ ).

Slug tests are a widely used method to measure saturated hydraulic conductivity, or how easily water flows through an aquifer, by perturbing the piezometric surface and measuring the time the local groundwater table takes to re-equilibrate. Saturated hydraulic conductivity is crucial to calculating the speed and direction of groundwater movement. Therefore, it is important to document data variance from in situ slug tests. This study addresses two potential sources of data variability: different users and different types of slug used. To test for user variability, two individuals slugged the same six wells with water multiple times at a stream meander on the East River near Crested Butte, CO. To test for variations in type of slug test, multiple water and metal slug tests were performed at a single well in the same meander. The distributions of hydraulic conductivities of each test were then tested for variance using both the Kruskal-Wallis test and the Brown-Forsythe test. When comparing the hydraulic conductivity distributions gathered by the two individuals, we found that they were statistically similar. However, we found that the two types of slug tests produced hydraulic conductivity distributions for the same well that are statistically dissimilar. In conclusion, multiple people should be able to conduct slug tests without creating any considerable variations in the resulting hydraulic conductivity values, but only a single type of slug should be used for those tests.

2016-03-01

Although client preferences are an integral component of evidence-based practice in psychology (American Psychological Association, 2006), relatively little research has examined what potential mental health consumers value in the psychotherapy they may receive. The present study was conducted to examine community members' preferences for the scientific and relational aspects of psychotherapy for different types of presenting problems, and how accurately therapists perceive these preferences. Community members (n = 200) were surveyed about the importance of scientific (e.g., demonstrated efficacy in clinical trials) and relational (e.g., therapist empathy) characteristics of psychotherapy both for anxiety disorders (e.g., obsessive-compulsive disorder) and disorder-nonspecific issues (e.g., relationship difficulties). Therapists (n = 199) completed the same survey and responded how they expected the average mental health consumer would. Results showed that although community members valued relational characteristics significantly more than scientific characteristics, the gap between these two was large for disorder-nonspecific issues (d = 1.24) but small for anxiety disorders (d = .27). Community members rated scientific credibility as important across problem types. Therapists significantly underestimated the importance of scientific characteristics to community members, particularly in the treatment of disorder-nonspecific issues (d = .74). Therapists who valued research less in their own practice were more likely to underestimate the importance of scientific credibility to community members. The implications of the present findings for understanding the nature of client preferences in evidence-based psychological practice are discussed. Copyright © 2015 Elsevier Ltd.

Microstructure feature of friction stir butt-welded ferritic ductile iron

International Nuclear Information System (INIS)

Chang, Hung-Tu; Wang, Chaur-Jeng; Cheng, Chin-Pao

2014-01-01

Highlights: • Defect-free ferritic ductile iron joints is fabricated by FSW. • The welding nugget is composed of graphite, martensite, and recrystallized ferrite. • The graphite displays a striped pattern in the surface and advancing side. • The ferritic matrix transforms into martensite structure during welding. • High degree of plastic deformation is found on the advancing side. - Abstract: This study conducted friction stir welding (FSW) by using the butt welding process to join ferritic ductile iron plates and investigated the variations of microsturcture in the joined region formed after welding. No defects appeared in the resulting experimental weld, which was formed using a 3-mm thick ductile iron plate and tungsten carbide alloy stir rod to conduct FSW at a rotational speed of 982 rpm and traveling speed of 72 mm/min. The welding region was composed of deformed graphite, martensite phase, and dynamically recrystallized ferrite structures. In the surface region and on the advancing side (AS), the graphite displayed a striped configuration and the ferritic matrix transformed into martensite. On the retreating side (RS), the graphite surrounded by martensite remained as individual granules and the matrix primarily comprised dynamically recrystallized ferrite. After welding, diffusion increased the carbon content of the austenite around the deformed graphite nodules, which transformed into martensite during the subsequent cooling process. A micro Vickers hardness test showed that the maximum hardness value of the martensite structures in the weld was approximately 800 HV. An analysis using an electron probe X-ray microanalyzer (EPMA) indicated that its carbon content was approximately 0.7–1.4%. The peak temperature on the RS, 8 mm from the center of the weld, measured 630 °C by the thermocouple. Overall, increased severity of plastic deformation and process temperature near the upper stir zone (SZ) resulted in distinct phase transformation

In this study, to investigate the shape of the back bead as a weld quality parameter and to select the optimal condition of the root-pass TIG welding of a horizontal butt-joint, an experimental design and the response surface method (RSM) have been employed. Three parameters are used as input variables, which include the base current, peak current, and welding speed. The back bead width is selected as an output variable representing the weld quality, the target value of the width is 5.4 mm. Conducting the experiments according to the Box-Behnken experimental design, a 2nd regression model for the back bead width was made, and the validation of the model was confirmed by using the F-test. The desirability function was designed through the nominal-the-best formula for the appropriate back bead width. Finally, the following optimal condition for welding was selected using the RSM: base current of 0.9204, peak current of 0.8676, and welding speed of 0.3776 in coded values. For verification, a test welding process under the optimal condition was executed and the result showed the back bead width of 5.38 mm that matched the target value well.

Technical Letter Report - Preliminary Assessment of NDE Methods on Inspection of HDPE Butt Fusion Piping Joints for Lack of Fusion

International Nuclear Information System (INIS)

2008-01-01

The U.S. Nuclear Regulatory Commission (NRC) has a multi-year program at the Pacific Northwest National Laboratory (PNNL) to provide engineering studies and assessments of issues related to the use of nondestructive evaluation (NDE) methods for the reliable inspection of nuclear power plant components. As part of this program, there is a subtask 2D that was set up to address an assessment of issues related to the NDE of high density polyethylene (HDPE) butt fusion joints. This work is being driven by the nuclear industry wanting to employ HDPE materials in nuclear power plant systems. This being a new material for use in nuclear applications, there are a number of issues related to its use and potential problems that may evolve. The industry is pursuing ASME Code Case N-755 entitled 'Use of Polyethylene (PE) Plastic Pipe for Section III, Division 1, Construction and Section XI Repair/Replacement Activities' that contains the requirements for nuclear power plant applications of HDPE. This Code Case requires that inspections be performed after the fusion joint is made by visually examining the bead that is formed and conducting a pressure test of the joint. These tests are only effective in general if gross through-wall flaws exist in the fusion joint. The NRC wants to know whether a volumetric inspection can be conducted on the fusion joint that will reliably detect lack-of-fusion conditions that may be produced during joint fusing. The NRC has requested that the work that PNNL is conducting be provided to assist them in resolving this inspection issue of whether effective volumetric NDE can be conducted to detect lack of fusion (LOF) in the butt HDPE joints. PNNL had 24 HDPE pipe specimens manufactured of 3408 material to contain LOF conditions that could be used to assess the effectiveness of NDE in detecting the LOF. Basic ultrasonic material properties were measured and used to guide the use of phased arrays and time-of-flight diffraction (TOFD) work that was

Safety of Sports for ICD Patients. The safety of sports participation for patients with implantable cardioverter defibrillators (ICDs) is unknown, and recommendations among physicians may vary widely. The purposes of this study were to determine current practice among patients with ICDs and their physicians regarding sports participation, and to determine how many physicians have cared for patients who have sustained adverse events during sports participation. A survey was mailed to all 1,687 U.S. physician members of the Heart Rhythm Society. Among 614 respondent physicians, recommendations varied widely. Only 10% recommended avoidance of all sports more vigorous than golf. Seventy-six percent recommended avoidance of contact, and 45% recommend avoidance of competitive sports. Most (71%) based restrictions on patients' underlying heart disease. Regardless of recommendations, most physicians (71%) reported caring for patients who participated in sports, including many citing vigorous, competitive sports, most commonly cited were basketball, running, and skiing. ICD shocks during sports were common, cited by 40% of physicians. However, few adverse consequences were reported. One percent of physicians reported known injury to patient (all but 3 minor); 5%, injury to the ICD system, and weightlifting and golf. Physician recommendations for sports participation for patients with ICDs varies widely. Many patients with ICDs do participate in vigorous and even competitive sports. While shocks were common, significant adverse events were rare.

Mears, Kim; Bandy, Sandra L

2017-04-01

The role of health sciences librarians has expanded in the scholarly communications landscape as a result of the increase in federal public access mandates and the continued expansion of publishing avenues. This has created the need to investigate whether academic health sciences libraries should have scholarly communications positions to provide education and services exclusively related to scholarly communication topics. A nine-question online survey was distributed through the Association of Academic Health Sciences Libraries (AAHSL) email discussion list to gather preliminary findings from and opinions of directors of health sciences libraries on the need for scholarly communications positions. The survey received a 38% response rate. The authors found that AAHSL members are currently providing scholarly communications services, and 46% of respondents expressed the need to devote a full-time position to this role. Our survey reveals a juxtaposition occurring in AAHSL member libraries. While administrators acknowledge the need to provide scholarly communications services, they often experience budget challenges in providing a full-time position for these services.

We conducted an Internet-based survey of European Society of Clinical Microbiology and Infectious Diseases members and affiliates, collecting data on hospital characteristics, ID management infrastructure, ID/IC-related activities and the ratio of physicians per 100 hospital beds. Regression analyses were conducted to examine factors associated with the physician-bed ratio. Five hundred sixty-seven hospital responses were collected between April and June 2015 from 61 countries, 81.2% (384/473) from Europe. A specialized inpatient ward for ID patients was reported in 58.4% (317/543) of hospitals. Rates of antibiotic stewardship programmes (ASP) and surveillance activities in survey hospitals were high, ranging from 88% to 90% for local antibiotic guidelines and 70% to 82% for programmes monitoring hospital-acquired infections. The median ID/CM/IC physician per 100 hospital beds ratio was 1.12 (interquartile range 0.56-2.13). In hospitals performing basic ASP and IC (including local antibiotic guidelines and monitoring device-related or surgical site infections), the ratio was 1.21 (interquartile range 0.57-2.14). Factors independently associated with higher ratios included compliance with European Union of Medical Specialists standards, smaller hospital size, tertiary-care institution, presence of a travel clinic, beds dedicated to ID and a CM unit. More than half of respondents estimated that additional staffing is needed for appropriate IC or ID management. No standard of physician staffing for ID/CM/IC in hospitals is available. A ratio of 1.21/100 beds will serve as an informed point of reference enabling ASP and infection surveillance. Copyright © 2016 European Society of Clinical Microbiology and Infectious Diseases.

Full Text Available It is important that married couples seek legal advice with regard to the assets falling within their joint estate, more particularly their retirement benefits. This article reflects on the entitlement (if any of non-member spouses to their spouses' retirement fund benefits. Pension benefits can be due before, during or after divorce, and parties to the marriage should be aware of their rights with regard to the accruing pension benefits of their spouses. While it is settled law that non-member spouses are entitled to receive a portion of their member spouses' pension benefits (known as "pension interest" immediately on divorce, it is not particularly clear whether non-member spouses are also entitled to receive the same before or sometime after divorce. In this article I provide a contextual understanding of the entitlements (if any which spouses or former spouses of members of pension funds have on such member spouses' retirement benefits. Furthermore, it shown in this article that various divisions of South African High Courts have been inconsistent in how they have approached the issue of the pension interest between divorcing spouses or divorced ex-spouses.

Effective leadership in salient groups: revisiting leader-member exchange theory from the perspective of the social identity theory of leadership.

Two studies compared leader-member exchange (LMX) theory and the social identity theory of leadership. Study 1 surveyed 439 employees of organizations in Wales, measuring work group salience, leader-member relations, and perceived leadership effectiveness. Study 2 surveyed 128 members of organizations in India, measuring identification not salience and also individualism/collectivism. Both studies provided good support for social identity predictions. Depersonalized leader-member relations were associated with greater leadership effectiveness among high-than low-salient groups (Study 1) and among high than low identifiers (Study 2). Personalized leadership effectiveness was less affected by salience (Study 1) and unaffected by identification (Study 2). Low-salience groups preferred personalized leadership more than did high-salience groups (Study 1). Low identifiers showed no preference but high identifiers preferred depersonalized leadership (Study 2). In Study 2, collectivists did not prefer depersonalized as opposed to personalized leadership, whereas individualists did, probably because collectivists focus more on the relational self.

Laughing off the Stereotypes: Age and Aging in Seniors' Online Sex-Related Humor.

Science.gov (United States)

Nimrod, Galit; Berdychevsky, Liza

2017-05-17

Focusing on sex, the most salient topic featured in ageist jokes, this study aims at exploring the extent to which seniors' own humor reflects common ageist stereotypes or rather echoes contemporary consumer society representations of seniors' sexuality. The study was based on a quantitative content analysis of 300 humorous sex-related messages posted during one full year by members of 14 leading online communities for seniors. Findings indicated that whereas the portrayal of older adults in humor typically relied on negative ageist stereotypes, their representation in seniors' online sex-related humor depended on the social identity of the butt of this humor. If it was an in-group member (oneself, another community member, or the community as a whole), the portrayal was rather positive, but when the butt belonged to the out-group (older adults in general), the depiction was far more ageist. Nonetheless, the representation of older butts of humor was generally more positive than that of the younger ones. These findings suggest that seniors tend to identify with current cultural representations of sexuality in later life and use sex-related humor as a personal means of resisting ageism. They apply two principal strategies: Distancing-reproducing certain ageist stereotypes by ascribing them to other older adults, but less so to their own group and even less than that to themselves-and equalizing older and younger individuals, even according the former an advantage regarding sexuality. © The Author 2017.

Amry Amin Abas; Noorhazleena Azaman; Mohd Yusnisyam Mohd Yusoff

2016-01-01

Ultrasonic testing is a proven reliable method which is able to detect and measure the size of defects in butt welds with acceptable tolerance. Recent advancement of technology has introduced a computerized technique which is phased array. Phased array employs focal law that enable focusing and steering of beam at the active aperture axis. This enables one line scanning but covering the whole weld volume as compared to conventional technique which employs aster scan and multiple probes to completely cover the whole weld volume. Phased array also gives multiple data view which assist the interpreter. This paper is about the study of these two techniques and technical analysis of comparison between the two. The conventional technique is performed using GE USM GO with 4 MHz 45 degrees shear wave probe. The phased array technique uses OLYMPUS OMNISCAN MX2 with 5L64 linear array probe with 16 elements aperture and 55 degrees wedge emitting shear wave into the specimen. Sensitivity of both techniques are based on 1.5 mm Side Drilled Hole. The results are compared and analysis such as defect sizing and defect type determination are performed. (author)

Discrimination and support from friends and family members experienced by people with mental health problems: findings from an Australian national survey.

Morgan, Amy J; Reavley, N J; Jorm, A F; Beatson, R

2017-11-01

To investigate the scope and nature of discrimination and positive treatment experienced by adults with mental health problems from their friends and family in a population-based survey. An Australian telephone-survey of 5220 adults included 1381 individuals who reported a mental health problem or scored high on a screening questionnaire. Respondents were interviewed about their experience of discrimination and positive treatment from their friends, spouse and other family members. Descriptions of experiences were content-analysed to identify key characteristics. Mental health diagnoses were primarily depression or anxiety disorders, and just over half had received treatment in the last 12 months. Positive treatment from family and friends was far more common than discrimination, reported by 74.1% of respondents. This was primarily characterised by providing emotional support and maintaining contact, as well as checking on their mental health and being a good listener. Nevertheless, discriminatory behaviours from friends and family were reported by 25.8% of respondents, with reducing or cutting contact being by far the most common. Friends and family also commonly dismissed that mental illness was real or caused suffering and showed a lack of understanding about mental health problems or treatments and how they can impact behaviour and functioning. This nationally representative study of real life experiences highlights the potential for harm or benefit from a person's social support network. Despite positive experiences being common, there is an ongoing need to reduce mental illness stigma and improve understanding of how to support a loved one with a mental health problem.

E-survey with researchers, members of ethics committees and sponsors of clinical research in Brazil: an emerging methodology for scientific research.

Dainesi, Sonia Mansoldo; Goldbaum, Moisés

2012-12-01

The growth of Internet users enables epidemiological studies to be conducted electronically, representing a promising methodology for data collection. Members of Ethics Committees, Clinical Researchers and Sponsors were interviewed using questionnaires sent over the Internet. Along with the questionnaire, participants received a message explaining the survey and also the informed consent. Returning the questionnaire meant the consent of the participant was given. No incentive was offered; two reminders were sent. The response rate was 21% (124/599), 20% (58/290) and 45% (24/53) respectively for Ethics Committees, Researchers and Sponsors. The percentage of return before the two reminders was about 62%. Reasons for non-response: participant not found, refusal to participate, lack of experience in clinical research or in the therapeutic field. Characteristics of participants: 45% of Ethics Committee participants, 64% of Researchers and 63% of Sponsors were male; mean age (range), respectively: 47 (28-74), 53 (24-72) and 40 (29-65) years. Among Researchers and Sponsors, all respondents had at least a university degree and, in the Ethics Committees group, only two (1.7%) did not have one. Most of the questionnaires in all groups came from the Southeast Region of Brazil, probably reflecting the highest number of clinical trials and research professionals in this region. Despite the potential limitations of a survey done through the Internet, this study led to a response rate similar to what has been observed with other models, efficiency in obtaining responses (speed and quality), convenience for respondents and low cost.

Influences of post weld heat treatment on tensile strength and microstructure characteristics of friction stir welded butt joints of AA2014-T6 aluminum alloy

Science.gov (United States)

Rajendran, C.; Srinivasan, K.; Balasubramanian, V.; Balaji, H.; Selvaraj, P.

2016-08-01

Friction stir welded (FSWed) joints of aluminum alloys exhibited a hardness drop in both the advancing side (AS) and retreating side (RS) of the thermo-mechanically affected zone (TMAZ) due to the thermal cycle involved in the FSW process. In this investigation, an attempt has been made to overcome this problem by post weld heat treatment (PWHT) methods. FSW butt (FSWB) joints of Al-Cu (AA2014-T6) alloy were PWHT by two methods such as simple artificial aging (AA) and solution treatment followed by artificial aging (STA). Of these two treatments, STA was found to be more beneficial than the simple aging treatment to improve the tensile properties of the FSW joints of AA2014 aluminum alloy.

2007-06-01

Community-driven, collaborative approaches to health promotion have the potential to enhance skills among community members and, in turn, increase community capacity. This study uses data from an evaluation of the California Healthy Cities and Communities (CHCC) Program to examine whether, and how, community problem-solving and collaboration skills are improved among coalition members and local coordinators in 20 participating communities. Methods include semi-structured interviews with coordinators and mailed surveys with coalition members (n=330 in planning phase and n=243 in implementation phase). The largest number of coordinators reported skill improvement in defining health broadly and assessing needs and assets. Similarly, coalition members reported greatest skill improvement for defining health broadly, assessing needs and assets and setting priorities and developing action plans. Modest correlations were observed between number of roles played in the local healthy cities and communities project and each skill area assessed. Time committed to the local CHCC coalition and its activities was not meaningfully correlated with any of the skills. Types of skill-building opportunities may be more important than number of hours devoted to meetings and activities in strengthening community problem-solving and collaboration skills among coalition members.

Regional anesthesia practice in China: a survey.

Science.gov (United States)

Huang, Jeffrey; Gao, Huan

2016-11-01

Neuraxial anesthesia has been widely used in China. Recently, Chinese anesthesiologists have applied nerve stimulator and ultrasound guidance for peripheral nerve blocks. Nationwide surveys about regional anesthesia practices in China are lacking. We surveyed Chinese anesthesiologists about regional anesthesia techniques, preference, drug selections, complications, and treatments. A survey was sent to all anesthesiologist members by WeChat. The respondents can choose mobile device or desktop to complete the survey. Each IP address is allowed to complete the survey once. A total of 6589 members read invitations. A total of 2654 responses were received with fully completed questionnaires, which represented an overall response rate of 40%. Forty-one percent of the respondents reported that more than 50% of surgeries in their hospitals were done under regional anesthesia. Most of the participants used test dose after epidural catheter insertion. The most common drug for test dose was 3-mL 1.5% lidocaine; 2.6% of the participants reported that they had treated a patient with epidural hematoma after neuraxial anesthesia. Most anesthesiologists (68.2%) performed peripheral nerve blocks as blind procedures based on the knowledge of anatomical landmarks. A majority of hospitals (80%) did not stock Intralipid; 61% of the respondents did not receive peripheral nerve block training. The current survey can serve as a benchmark for future comparisons and evaluation of regional anesthesia practices in China. This survey revealed potential regional anesthesia safety issues in China.

The goal of the Strong4Life School Nutrition Program is to promote healthy eating in school cafeterias in Georgia by training school nutrition managers and staff members to implement changes in the cafeteria to nudge children to make healthier choices. The objective of our study was to evaluate program effect on (1) school nutrition manager and staff member knowledge of evidence-based strategies and their self-efficacy to make positive changes, (2) the school cafeteria environment, and (3) National School Lunch Program participation. We assessed changes in participant knowledge, beliefs, and self-efficacy by administering a survey before and after training (February-July 2015); a follow-up survey (3 school months posttraining) assessed changes in the cafeteria. A total of 842 school nutrition managers and staff members were trained and completed pre- and posttraining surveys; 325 managers completed the follow-up survey. We used cafeteria records from a subsample of the first schools trained (40 intervention and 40 control) to assess National School Lunch Program participation. From pretraining to posttraining, we found a significant increase in manager and staff member (n = 842) knowledge of strategies for enhancing taste perception through the use of creative menu item names (from 78% to 95%, P managers (n = 325) reported increased use of evidence-based serving strategies: visibility (from 84% to 96% for placing healthy options in >2 locations, P managers and staff members in Smarter Lunchrooms Movement techniques may be an effective way to make changes in the school cafeteria environment to encourage healthier choices among students. Additional studies allowing time for more complex changes to be implemented are needed to assess the full effect of the program.

Cadzow, Renee B; Craig, Mary; Rowe, Jimmy; Kahn, Linda S

2013-01-01

The purpose of this study was to evaluate a community-based diabetes education pilot project. The Neighborhood Health Talker project aimed to train and implement cultural health brokers primarily targeting communities of color to improve community members' diabetes knowledge and diabetes self-management skills. A secondary aim was to establish diabetes resource libraries accessible to communities that normally experience barriers to these resources. Recruited community members completed 1 week of formal training developed by a multidisciplinary team in Buffalo, NY. The effect of training was evaluated through the use of baseline surveys, a pretest/posttest covering all training content, and daily quizzes evaluating knowledge relevant to each of the five training modules. Trained NHTs then held at least five community conversations in various locations and administered anonymous postconversation surveys to participants. Descriptive statistics and qualitative analysis techniques were used to summarize test, quiz, and survey results. Twelve women and 1 man completed the training program. Working alone as well as in pairs, each held at least five community conversations reaching over 700 community members of all ages over 3 months and established 8 diabetes resource libraries in the community. All trainees increased their diabetes knowledge and confidence as well as their abilities to perform the tasks of a cultural health broker. Trainees also indicated that the goals they set at training initiation were met. The training was successful in increasing trainee knowledge and confidence about diabetes prevention and self-management. Participants not only developed proficiency in discussing diabetes, they also made important lifestyle changes that demonstrated their commitment to the cause and the project. Low-cost initiatives like this are easily reproducible in other communities of color and could be modified to meet the needs of other communities as well.

2018-02-01

Our main objective was to assess patient and family members' perception of bad news communication in the emergency department (ED) and compare these with physicians' perceptions. This is a cross-sectional study carried out at the ED of a tertiary teaching hospital. To compare physicians' and receivers' (patient and/or family member) perceptions, we created a survey based on the six attributes derived from the SPIKES protocol. The surveys were applied immediately after communication of bad news occurred in the ED. We analyzed agreement among participants using κ-statistics and the χ-test to compare proportions. A total of 73 bad news communication encounters were analyzed. The survey respondents were 73 physicians, 69 family members, and four patients. In general, there is a low level of agreement between physicians' and receivers' perceptions of how breaking bad news transpired. The satisfaction level of receivers, in terms of breaking bad news by doctors, presented a mean of 3.7±0.6 points. In contrast, the physicians' perception of the communication was worse (2.9±0.6 points), with P value less than 0.001. Doctors and receivers disagree in relation to what transpired throughout bad news communications. Discrepancies were more evident in issues involving emotion, invitation, and privacy. An important agreement between perceptions was found in technical and knowledge-related aspects of the communication.

Stress experiences of family members of registered sex offenders.

Science.gov (United States)

Tewksbury, Richard; Levenson, Jill

2009-01-01

The collateral consequences of sex offender registration and notification (SORN) have been well established, although little evidence has supported the efficacy of SORN. Based on the belief that family members provide some of the most consistent, important, and intense forms of support for criminal offenders in general and registered sex offenders (RSOs) more specifically, the experiences of sanctions, losses, and stresses of these individuals is examined. Using survey responses from 584 individuals known to visit online support and advocacy groups for RSOs and their loved ones, this study identifies the stress levels and stressors experienced by this population. Findings show that family members of RSOs experience high levels of social isolation, fear, shame, property damage, and forced residential relocation. Perceived stress is significantly higher for those who are of lower economic means, feel isolated, have high levels of fear and shame/embarrassment, or were forced to move.

2018-01-01

Surveys of bereaved family members are increasingly being used to evaluate end-of-life (EOL) care and to measure organizational performance in EOL care quality. The Bereaved Family Survey (BFS) is used to monitor EOL care quality and benchmark performance in the Veterans Affairs (VA) health-care system. The objective of this study was to develop a case-mix adjustment model for the BFS and to examine changes in facility-level scores following adjustment, in order to provide fair comparisons across facilities. We conducted a cross-sectional secondary analysis of medical record and survey data from veterans and their family members across 146 VA medical centers. Following adjustment using model-based propensity weighting, the mean change in the BFS-Performance Measure score across facilities was -0.6 with a range of -2.6 to 0.6. Fifty-five (38%) facilities changed within ±0.5 percentage points of their unadjusted score. On average, facilities that benefited most from adjustment cared for patients with greater comorbidity burden and were located in urban areas in the Northwest and Midwestern regions of the country. Case-mix adjustment results in minor changes to facility-level BFS scores but allows for fairer comparisons of EOL care quality. Case-mix adjustment of the BFS positions this National Quality Forum-endorsed measure for use in public reporting and internal quality dashboards for VA leadership and may inform the development and refinement of case-mix adjustment models for other surveys of bereaved family members.

Purpose: The main objective of this survey is to describe the current practice of thoracic anesthesia in the Middle Eastern (ME) region. Methods: A prospective online survey. An invitation to participate was e-mailed to all members of the ME thoracic-anaesthesia group. A total of 58 members participated in the survey from 19 institutions in the Middle East. Questions concerned ventilation strategies during one-lung ventilation (OLV), anesthesia regimen, mode of postoperative analgesia, use of lung isolation techniques, and use of i.v. fluids. Results: Volume-controlled ventilation was favored over pressure-controlled ventilation (62% vs 38% of respondents, Panesthesia practice. Failure to pass a DLT and difficult airway are the most commonly cited indications for BB use. Regarding postoperative analgesia, the majority 61.8% favor thoracic epidural analgesia over other techniques (P<0.05). Conclusions: Our survey provides a contemporary snapshot of the ME thoracic anesthetic practice. PMID:23162388

Marine environmental radioactivity surveys at nuclear submarine berths 2001

Cowling, E.; Ball, R.; Simpson, C.

2002-01-01

This report presents the results of the marine environmental radioactivity monitoring surveys of intertidal and underwater areas around nuclear submarine berths which were carried out by DRPS during 2001. Also included are results of smaller scale intertidal surveys carried out by local staff but co-ordinated by DRPS. Cobalt-60, the nuclide of major importance in naval discharges, was detected in a number of samples but in many cases was attributable to discharges by other operators. Concentrations in any case were found to be low, and at no survey location did the calculated annual radiation dose commitment to the most exposed members of the general public due to the presence of cobalt-60 exceed 1% of the ICRP principal dose limit for members of the public (1000μSv). These results are consistent with those obtained in the independent monitoring programmes as reported in the Radioactivity in Food and the Environment (RIFE) annual reports. It is concluded that existing discharge arrangements are providing effective control over environmental levels of radioactivity, and that there has been no radiological hazard to any member of the general public during 2001 from the operation of nuclear powered submarines.

To assess the current practice patterns of radiologists who perform transthoracic needle biopsy (TNB). An email survey of 71 questions on TNB was sent to 240 members of the Korean Society of Thoracic Radiology. The answers to multiple-choice questions (n = 56) were analyzed. Of 60 respondents, 45% had 10 or more years of experience in chest radiology, and 70% had 5 or more years of experience in TNB. For the question on the most frequently used diagnostic method for lesions with high probability of being resectable-stage lung cancer, 70% of respondents answered that TNB is initially used, with or without bronchoscopy. In patients at high-risk of TNB-related complications, the proportion of the respondents who consistently declined TNB was only 5%. The number of rebiopsies was said to be increased; molecular analysis for an established target therapy (43.6%) and clinical trial of a new drug (28.2%) were the two most common reasons for it. The most popular needle type was the coaxial cutting needle (55%), and the popular guiding modality was conventional computed tomography (CT) (56.7%). In addition, 15% of respondents have encountered air embolism. Despite high variation in how TNB is being performed in Korea, some patterns were noted. It is common for patients with resectable-stage lung cancer to undergo TNB prior to surgery. Rebiopsy is now more common than before, with personalized medicine as the most important reason for it. The most popular type of needle is the coaxial system; the most popular modality for guidance is still CT

Full Text Available Background and purpose: Evaluation of faculty members is a kind of educational evaluation to determine success of faculty members in reaching the educational goals. Regarding the controversy about the validity of this kind of evaluation, this study was done to examine faculty members and students view point about content and implementation of evaluation of faculty members by students and feedback of the results in the second term of academic year 2003-4 in Birjand University of Medicine.Methods: All faculty members and students participated in this descriptive study. Their opinions were studied using two questionnaires for students and faculty members separately, whose content validity were confirmed after a survey from specialists and pilot study and reliability of results werestudied through calculating Cronbach’s alpha coefficient for internal consistency .Data were analyzed through calculating frequencies and K2-test, α=0.05.Results: Of all faculty members, 95% ( 30 from clinical and 30 from non clinical departments were aware of having been evaluated by students, 81.7% of them recognize educational development center of the University as the responsible body for evaluation. 91.7% of them received the feedback of the evaluation results. 45% of them agreed that announcement of evaluation results was helpful to improve teaching. 40% believed that questionnaires were responded without dutifulness andcarefulness by students.Conclusion: The aim of teaching evaluation is to improve teaching by faculty members. But it seems that many faculty members do not regard this evaluation tool so valid for measuring their teaching activities. The inappropriateness of most of the questionnaires, unfair judgment of student, and careless selection of the sample of students who answer the questionnaires are major issues for further development.Key words: EVALUATION, FACULTY MEMBER, STUDENT, MEDICAL UNIVERSITY OF BIRJAND

The aim of this study was to compare the learning preferences of millennial dental hygiene students (born between 1982 and 2002) in the U.S. with the teaching methods used by their non-millennial instructors. Cross-sectional surveys were developed with 21-item, five-point Likert scales to examine students' preferences for and faculty use of lecture, collaborative activities, technology, independent work, and group discussion. Surveys were emailed to U.S. dental hygiene program directors in September 2015. The respondents totaled 800 students and 343 faculty members-approximately 5% of all dental hygiene students and 6.8% of all dental hygiene faculty members in the U.S. The results showed that the responding faculty members (88.7%) used case studies more than the students (61.2%) preferred and that the students (71.4%) preferred games when learning more than the faculty members (57.2%) used them (pStudent respondents (82.1%) preferred handouts for lecture more than did the faculty respondents (58.8%; pstudents to read before class 39.3% more than student respondents read (pStudent respondents preferred study guides for exams 39.2% more than the faculty respondents provided them (pstudents work in groups more than these students preferred (57.8%), and 92% of these faculty members used group activities in class (pstudents in this study were consistent with previous research on millennial traits. This study found areas of disagreement between students and faculty members on the use of case studies, study guides, and group work. Although these students stated they preferred lecture over group work, trends in education stress using active learning over lecture.

Cappell, Sylvain; Rosenberg, Jonathan

2014-01-01

Surgery theory, the basis for the classification theory of manifolds, is now about forty years old. The sixtieth birthday (on December 14, 1996) of C.T.C. Wall, a leading member of the subject''s founding generation, led the editors of this volume to reflect on the extraordinary accomplishments of surgery theory as well as its current enormously varied interactions with algebra, analysis, and geometry. Workers in many of these areas have often lamented the lack of a single source surveying surgery theory and its applications. Because no one person could write such a survey, the editors ask

There are currently no evidence-based indications for surgical stabilization of rib fractures (SSRF) in patients without flail chest. The purpose of this survey was to identify patients for whom there is relative equipoise (operative vs. non-operative) in order to assist in designing a randomized clinical trial. Members of the Chest Wall Injury Society were sent an online survey, in which 18 patient scenarios were presented. The baseline patient had ≥ three displaced, contiguous fractures and had no other contraindications for surgery. This default scenario was then varied based upon patient age, degree of traumatic brain injury (TBI), fracture series location, and number of abnormal pulmonary physiologic variables (oxygen requirement, respiratory rate, incentive spirometry ability, cough, and numeric pain score). Thirty respondents provided a total of 540 answers. Overall, the majority of responses were in favor of SSRF (n = 413, 84.1%). Furthermore, the vast majority of responses indicated that some degree of pulmonary compromise was necessary to recommend SSRF (n = 44, 90.4%), with ≥ two abnormal parameters being the most common threshold (n = 156, 31.8%). Decision to recommend SSRF varied significantly by number of abnormal clinical variables, age, and degree of TBI, but not by fracture series location. Patients aged 85 years old and those with moderate TBI were the least likely to be recommended for SSRF, regardless of abnormal pulmonary physiologic variables. The most appropriate cutoff for equipoise appeared to be a patient aged 21-79 years old, with no or mild TBI, ≥ two abnormal pulmonary parameters, and regardless of fracture location (44.8% consensus for SSRF). SSRF was recommended for most patients with non-flail, displaced rib fractures. However, this recommendation was contingent upon patient age, degree of TBI, and pulmonary clinical status. Results of this survey may be used to inform inclusion criteria for a future randomized

: Failure mode and effects analysis (FMEA) is a commonly used prospective risk assessment approach in health care. Failure mode and effects analyses are time consuming and resource intensive, and team performance is crucial for FMEA success. We evaluate FMEA team members' perceptions of FMEA team performance to provide recommendations to improve the FMEA process in health care organizations. : Structured interviews and survey questionnaires were administered to team members of 2 FMEA teams at a Midwest Hospital to evaluate team member perceptions of FMEA team performance and factors influencing team performance. Interview transcripts underwent content analysis, and descriptive statistics were performed on questionnaire results to identify and quantify FMEA team performance. Theme-based nodes were categorized using the input-process-outcome model for team performance. : Twenty-eight interviews and questionnaires were completed by 24 team members. Four persons participated on both teams. There were significant differences between the 2 teams regarding perceptions of team functioning and overall team effectiveness that are explained by difference in team inputs and process (e.g., leadership/facilitation, team objectives, attendance of process owners). : Evaluation of team members' perceptions of team functioning produced useful insights that can be used to model future team functioning. Guidelines for FMEA team success are provided.

To achieve high safety levels, mere compliance with safety regulations is not sufficient; employees must be proactive and demonstrate safety citizenship behaviors. Trust is considered as a mechanism for facilitating the effects of a leader on employee citizenship behaviors. Increasingly research has focused on the role of trust in a safety context; however, the role of coworker trust has been overlooked. The mediating role of coworker trust in the relationship between the leader-member exchange and safety citizenship behavior is the focus of this field study. Front-line employees from an air traffic control center and an airline maintenance department completed surveys measuring leader-member exchange, co-worker trust, and safety citizenship behavior. Structural Equation Modeling revealed affective and cognitive trust in coworkers is influenced by leader-member exchange. A trust-based mediation model where cognitive trust and affective trust mediate the relationship between the leader-member exchange and safety citizenship behavior emerged. Results of this study add to our understanding of the relationship between leader-member exchange and safety behavior. The effect of co-worker trust and the extent to which employees participate in workplace safety practice were identified as critical factors. The findings show that managers need to focus on developing cognitive and affective coworker trust to improve safety citizenship behaviors.

Bullock, Emma

2017-01-01

Background A growing number of online communities have been established to support those who self-harm. However, little is known about the therapeutic affordances arising from engagement with these communities and resulting outcomes. Objective The aim of this study was to explore the presence of therapeutic affordances as reported by members of self-harm online support communities. Methods In total, 94 respondents (aged 13-63 years, mean=23.5 years; 94% female) completed an online survey exploring their experiences of engaging with a self-harm online support community. Respondents varied in terms of how long they had been accessing an online community, with 22% (21/94) accessing less than 1 year, 39% (37/94) 1 to 2 years, 14% (13/94) 2 to 3 years, and 24.5% (23/94) more than 3 years. Responses were analyzed using deductive thematic analysis. Results The results of our analysis describe each of the five therapeutic affordances that were present in the data, namely (1) connection, the ability to make contact with others who self-harm for the purposes of mutual support and in so doing reduce feelings of loneliness and isolation; (2) adaptation, that is, how use of online support varies in relation to the personal circumstances of the individual user; (3) exploration, that is, the ability to learn about self-harm and learn about strategies to reduce or stop self-harming behavior; (4) narration, that is, the ability to share experiences, as well as read about the experiences of others; and (5) self-presentation, that is, how and what users present about themselves to others in the online community. Conclusions Our findings suggest that engagement with self-harm online support communities may confer a range of therapeutic benefits for some users, which may serve to minimize the psychosocial burden of self-harm and promote positive coping strategies. In addition, the online nature of the support available may be helpful to those who are unable to access face

A natural radiation survey of a cross-section of homes in the UK has been under way for over a year. Members of the public are contacted by post by the NRPB and asked whether they would be willing to have dosemeters in their homes for 12 months. To date the survey has elicited approximately 50% positive response for over a year which is encouragingly high compared to response rates of postal surveys in general. The survey has attracted notable media attention; in the main the tenor of the stories has been accurate and informative and only a handful could be described as sensational.

Education methods have undergone transformation over the centuries. Use of technology is the cornerstone for innovation in teaching methods. Hence, blended learning which includes face to face and online modalities is being increasingly explored as effective method for learning. This pilot study determines the perceptions of faculty members in a private international university on barriers influencing adoption of technology for teaching and learning. A cross-sectional survey was conducted through a self-reported questionnaire using 'survey monkey'. The data was entered and analyzed using Statistical Package for the Social Sciences (SPSS version 20). Frequencies and proportions are reported. Findings indicated that 51.6% faculty members perceived the importance of integration of technology in their teaching. Around 54% of the participants recognized that they do possess the ability and accessibility to integrate information communication technology (ICT) in teaching and learning, but there is a need to hone the basic information technology (IT) skills to initiate technology driven teaching. Findings revealed that 55% faculty members acknowledged the constraint of not getting protective time to develop and deliver technology driven courses. Further, results showed that 45% faculty members perceived that their innovation efforts in terms of teaching as blended learning do not count towards their professional promotion or recognition, as usually priority is given to research over teaching innovation. The findings also indicated that 54.5% participants asserted that university lack mentorship in the field of blended learning. Therefore, study suggests that universities should provide adequate mentorship programmes for the faculty members in enhancing their skills of integrating technology in their teaching.

2012-11-01

The United States has the highest incarceration rate in the world, yet there is relatively little information on how the removal of these adults from households impacts the youth who are left behind. This study used a child-centered lens to examine the impact of incarceration on the school outcomes of youth who resided with a family member or family associate who was incarcerated prior to the youth's 18th birthday. We used data from 11 waves of the National Longitudinal Survey of Youth: Child and Young Adult (n = 3,338, 53 % female). Initial analyses indicated that youth who experienced a household members' incarceration evidenced more socioeconomic challenges, more frequent home adversities, and lower cognitive skills relative to youth who did not experience a household members' incarceration. Results also revealed that youth who had experienced a household member's incarceration were more likely to report extended absence from school and were less likely to graduate from high school relative to those youth who did not experience a household members' incarceration. Counter to our hypotheses, results revealed the incarceration of an extended family member being in the household was the only relation significantly associated with worse school outcomes. Plausibly, families who allow non-immediate criminally involved individuals to reside in the household are experiencing a more pervasive chaotic home environment than those with a parent or sibling incarcerated. Our study suggests that efforts to address the needs of children with incarcerated parents need to be widened to those who experience the loss of any household member due to incarceration.

To evaluate possible variability in chest radiologists' interpretations of the Lung Imaging Reporting and Data System (Lung-RADS) on difficult-to-classify scenarios. Ten scenarios of difficult-to-classify imaginary lung nodules were prepared as an online survey that targeted Korean Society of Thoracic Radiology members. In each question, a description was provided of the size, consistency, and interval change (new or growing) of a lung nodule observed using annual repeat computed tomography, and the respondent was instructed to choose one answer from five choices: category 2, 3, 4A, or 4B, or 'un-categorizable.' Consensus answers were established by members of the Korean Imaging Study Group for Lung Cancer. Of the 420 answers from 42 respondents (excluding multiple submissions), 310 (73.8%) agreed with the consensus answers; eleven (26.2%) respondents agreed with the consensus answers to six or fewer questions. Assigning the imaginary nodules to categories higher than the consensus answer was more frequent (16.0%) than assigning them to lower categories (5.5%), and the agreement rate was below 50% for two scenarios. When given difficult-to-classify scenarios, chest radiologists showed large variability in their interpretations of the Lung-RADS categories, with high frequencies of disagreement in some specific scenarios.

Euphorbiaceae represents flowering plants family of tropical and sub-tropical region rich in secondary metabolites of economic importance. To understand and assess the genetic makeup among the members, this study was undertaken to characterize and compare SSR markers from publicly available ESTs and GSSs of nine selected species of the family. Mining of SSRs was performed by MISA, primer designing by Primer3, while functional annotation, gene ontology (GO) and enrichment analysis were performed by Blast2GO. A total 12,878 number of SSRs were detected from 101,701 number of EST sequences. SSR density ranged from 1 SSR/3.22 kb to 1 SSR/15.65 kb. A total of 1873 primer pairs were designed for the annotated SSR-Contigs. About 77.07% SSR-ESTs could be assigned a significant match to the protein database. 3037 unique SSR-FDM were assigned and IPR003657 (WRKY Domain) was found to be the most dominant FDM among the members. 1810 unique GO terms obtained were further subjected to enrichment analysis to obtain 513 statistically significant GO terms mapped to the SSR containing ESTs. Most frequent enriched GO terms were, GO:0003824 for molecular function, GO:0006350 for biological process and GO:0005886 for cellular component, justifying the richness of defensive secondary metabolites and phytomedicine within the family. The results from this study provides tangible insight to genetic make-up and distribution of SSRs. Functional annotation corresponded many genes of unknown functions which may be considered as novel genes or genes responsible for stress specific secondary metabolites. Further studies are required to understand stress specific genes accountable for leveraging the synthesis of secondary metabolites.

Full Text Available Introduction: Development of information literacy is considered a required factor for instructors of higher education system due to its impact on educational and research activities, and performance of educational academic members is a main factor that affects the output of system. The aim of this study was to report and compare the information literacy among the academic members of departments of clinical and basic biomedical sciences in 2011. Methods: A cross-sectional survey was performed using a valid and reliable questionnaire distributed among 48 full-time equivalent academic members of Zabol University of Medical Sciences in both clinical (19 members and basic biomedical departments (29 members. Data were analyzed using Fisher, Mann-Whitney and Chi-square statistics in SPSS 17. Results: Information literacy of the members was at an average level at both knowledge and attitude levels but it was low at the practice. There was a significant difference between two groups in terms of awareness about information resources; however, the difference was not significant for the utilization of information resources. Conclusion: Members of department of basic biomedical sciences were more aware than those of clinical department about the information resources but such awareness has not resulted in more use of resources in the educational and research activities. Despite positive attitude of all members towards the application of electronic information resources in both educational and research activities, their awareness of information literacy skills and practicing were not satisfying in educational and research sections. As a final point, Information literacy is hence suggested as a part of continuing medical education courses.

The quality of communication with patients and family members in intensive care units (ICUs) is a focus of current interest for clinical care improvement. Electronic communication portals are commonly used in other healthcare settings to improve communication. We do not know whether patients and family members desire such portals in ICUs, and if so, what functionality they should provide. To define interest in and desired elements of an electronic communication portal among current and potential ICU patients and their family members. We surveyed, via an Internet panel, 1,050 English-speaking adults residing in the United States with a personal or family history of an ICU admission within 10 years (cohort A) and 1,050 individuals without a history of such admission (cohort B). We also administered a survey instrument in person to 105 family members of patients currently admitted to ICUs at an academic medical center in Boston (cohort C). Respondents, especially current ICU family members, supported an electronic communication portal, including access via an electronic tablet. They wanted at least daily updates, one-paragraph summaries of family meetings including a list of key decisions made, and knowledge of the role and experience of treating clinicians. Overall, they preferred detailed rather than "big picture" information. Respondents were generally comfortable sharing information with their family members. Preferences regarding a communication portal varied significantly by age, sex, ethnicity, and prior experience with ICU hospitalization. Electronic communication portals appear welcome in contemporary ICUs. Frequent updates, knowledge about the professional qualifications of clinicians, detailed medical information, and documentation of family meetings are particularly desired.

North American optometry and ophthalmology faculty members and vision science librarians were surveyed online (14% response rate) about teaching evidence-based practice (EBP). Similar to studies of other health care programs, all five EBP steps (Ask, Acquire, Appraise, Apply, Assess) were taught to varying degrees. Optometry and ophthalmology EBP educators may want to place further emphasis on (1) the Apply and Assess steps, (2) faculty- and student-generated questions and self-assessment in clinical settings, (3) online teaching strategies, (4) programmatic integration of EBP learning objectives, and (5) collaboration between faculty members and librarians.

Survey of industrial radioisotope savings

International Nuclear Information System (INIS)

1965-01-01

Only three decades after the discovery of artificial radioactivity and two after radioisotopes became available in quantity, methods employing these as sources or tracers have found widespread use, not only in scientific research, but also in industrial process and product control. The sums spent by industry on these new techniques amount to millions of dollars a year. Realizing the overall attitude of industry to scientific progress - to accept only methods that pay relatively quickly - one can assume that the economic benefits must be of a still larger order of magnitude. In order to determine the extent to which radioisotopes are in daily use and to evaluate the economic benefits derived from such use, IAEA decided to make an 'International Survey on the Use of Radioisotopes in Industry'. In 1962, the Agency invited a number of its highly industrialized Member States to participate in this Survey. Similar surveys had been performed in various countries in the 1950's. However, the approaches and also the definition of the economic benefits differed greatly from one survey to another. Hence, the Agency's approach was to try to persuade all countries to conduct surveys at the same time, concerning the same categories of industries and using the same terms of costs, savings, etc. In total, 24 Member States of the Agency agreed to participate in the survey and in due course they submitted contributions. The national reports were discussed at a 'Study Group Meeting on Radioisotope Economics', convened in Vienna in March 1964. Based upon these discussions, the national reports have been edited and summarized. A publication showing the administration of the Survey and providing all details is now published by the Agency. From the publication it is evident that in general the return of technical information was quite high, of the order of 90%, but, unfortunately the economic response was much lower. However, most of the reports had some bearing on the economic aspects

The evaluations on institutionalized care facilities from family members, after their loved ones moved into such services, are very different from culture to culture, family to family and person to person. According to a recent survey in the United States and China, it is found that different cultures and the different health conditions of the residents strongly influence family member's viewpoints on institutionalized care services. It is also found that the availability of the institutionalized care facilities plays a significant role, which strongly affects family members' evaluations on nursing home services.

Deployment affects not just the service members, but also their family members back home. Accordingly, this study examined how resilient family processes during a deployment (i.e., frequency of communication and household management) were related to the personal reintegration of each family member (i.e., how well each family member begins to "feel like oneself again" after a deployment), as well as several indicators of subjective well-being. Drawing from the family attachment network model (Riggs & Riggs, 2011), the present study collected survey data from 273 service members, their partners, and their adolescent children. Resilient family processes during the deployment itself (i.e., frequency of communication, household management), postdeployment positive and negative personal reintegration, and several indicators of well-being were assessed. Frequency of communication was related to personal reintegration for service members, while household management was related to personal reintegration for nondeployed partners; both factors were related to personal reintegration for adolescents. Negative and positive personal reintegration related to a variety of subjective well-being outcomes for each individual family member. Interindividual (i.e., crossover) effects were also found, particularly between adolescents and nondeployed partners. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

When subjected to temperature changes and restrained from free movement, a member develops stresses. Restrained members are sometimes assumed to act independently of other members. A method of analysis and design for thermal stresses in such members is provided. The method of analysis, based on the ultimate strength concept, greatly reduces the computational efforts for determining thermal effects in concrete members. Available charts and tables and the recommendations given herein simplify the design. (Auth.)

We present the results of SPT-GMOS, a spectroscopic survey with the Gemini Multi-Object Spectrograph (GMOS) on Gemini South. The targets of SPT-GMOS are galaxy clusters identified in the SPT-SZ survey, a millimeter-wave survey of 2500 deg 2 of the southern sky using the South Pole Telescope (SPT). Multi-object spectroscopic observations of 62 SPT-selected galaxy clusters were performed between 2011 January and 2015 December, yielding spectra with radial velocity measurements for 2595 sources. We identify 2243 of these sources as galaxies, and 352 as stars. Of the galaxies, we identify 1579 as members of SPT-SZ galaxy clusters. The primary goal of these observations was to obtain spectra of cluster member galaxies to estimate cluster redshifts and velocity dispersions. We describe the full spectroscopic data set and resulting data products, including galaxy redshifts, cluster redshifts, and velocity dispersions, and measurements of several well-known spectral indices for each galaxy: the equivalent width, W , of [O ii] λλ 3727, 3729 and H- δ , and the 4000 Å break strength, D4000. We use the spectral indices to classify galaxies by spectral type (i.e., passive, post-starburst, star-forming), and we match the spectra against photometric catalogs to characterize spectroscopically observed cluster members as a function of brightness (relative to m ⋆ ). Finally, we report several new measurements of redshifts for ten bright, strongly lensed background galaxies in the cores of eight galaxy clusters. Combining the SPT-GMOS data set with previous spectroscopic follow-up of SPT-SZ galaxy clusters results in spectroscopic measurements for >100 clusters, or ∼20% of the full SPT-SZ sample.

2017-08-01

Community coalitions have proliferated as a means of addressing a range of complex community problems. Such coalitions often consist of a small paid staff and volunteer members. The present study examines one likely contributor to coalition effectiveness: the degree of agreement on role expectations between paid staff and volunteer members. Role confusion occurs when paid staff and volunteers differ in their expectations of who is responsible for accomplishing specific tasks. Staff and volunteer members from 69 randomly selected Drug Free Coalitions in the United States as well as 21 Drug Free Coalitions in Connecticut were asked to respond to an online survey asking about 37 specific coalition tasks critical for effective coalition functioning and the degree to which paid staff and/or voluntary members should be responsible for accomplishing each. Our final sample consisted of 476 individuals from 35 coalitions. Using coalitions as the unit of analysis, we found significant differences between paid staff and volunteer coalition members on nine tasks reflecting four domains: meeting leadership and participation, (2) planning and implementation leadership, (3) publicity/media relations, and (4) logistical functions. Implications of these differences and ways that evaluators could help coalitions deal with differing role expectations were discussed. Copyright © 2017 Elsevier Ltd. All rights reserved.

This paper presents results from the inaugural Scope of Practice Survey of Optometry Australia members conducted in October 2015. The survey gathered information related to confidence in detecting and diagnosing key ocular conditions, grading diabetic retinopathy, prescribing scheduled medicines, access to equipment, confidence using equipment, incidence of patients requiring therapeutic management, referral practices and services provided. The survey was developed, piloted, modified and administered to members of Optometry Australia (excluding student and retired members), who had a current email address. Results were collated and analysed using Microsoft Excel. Of the 587 optometrists in clinical practice who responded, 254 (43 per cent) had therapeutic endorsement of registration. The majority of respondents practised in a major city or surrounding suburbs (63 per cent). Independent practice was the most frequently cited practice type (58 per cent). The estimated average number of patients seen in a week was 48; there was a steady decrease in the number of patients per week with increasing age, from 53 for optometrists in their 20s to 27 for optometrists aged over 70. There was very high confidence (over 93 per cent) in ability to grade diabetic retinopathy and diagnose a range of ocular conditions. Confidence in performance of more advanced techniques was higher for endorsed than non-endorsed optometrists. Approximately 12 per cent of patients required a Schedule 4 therapeutic prescription. The most frequently recommended over-the-counter medications were for dry eye for both endorsed and non-endorsed optometrists. The most frequently prescribed Schedule 4 medications were anti-inflammatories. The most challenging conditions to prescribe for were glaucoma, microbial keratitis and uveitis. Approximately one in six therapeutically endorsed optometrists reported unexpected side effects of medications they had prescribed. Information from the survey will guide

Identifying ways to efficiently maximize the response rate to surveys is important to survey-based research. However, evidence on the response rate effect of donation incentives and especially altruistic and egotistic-type text appeal interventions is sparse and ambiguous. By a randomized survey...... experiment among 6,162 members of an online survey panel, this article shows how low-cost incentives and cost-free text appeal interventions may impact the survey response rate in online panels. The experimental treatments comprise (a) a cash prize lottery incentive, (b) two donation incentives equating...... survey response with a monetary donation to a good cause, (c) an egotistic-type text appeal, and (d) an altruistic-type text appeal. Relative to a control group, we find higher response rates among the recipients of the egotistic-type text appeal and the lottery incentive. Donation incentives yield lower...

A survey in Latin America;Survey of atomic energy needs

An eight-member mission of the International Atomic Energy Agency visited Brazil and Venezuela last summer to survey their atomic energy needs and the conditions that may have a bearing on the fulfilment of these needs. The head of the mission and two members also visited Argentina to make a study in a more restricted sphere. While the mission's work in Brazil and Venezuela covered all aspects of atomic energy development, the investigations in Argentina were concerned specifically with the exploration, mining and processing of nuclear raw materials. The members of the mission held extensive discussions with the national authorities in charge of atomic energy development who acquainted them with their plans and the progress of work already undertaken. The IAEA experts also visited different centres of work to gain a first-hand knowledge of conditions and needs. They were thus able to advise the national authorities on lines of further development and assist them in formulating requests for technical assistance from the Agency. The information contained in the mission's reports may serve as a broad guide to the present state and future needs of atomic energy development in the three countries

The COOPRA LPSD working group is charged with the responsibility to assess their Member country's plant operations at Low Power and Shutdown (LPSD) conditions. The sharing of information is expected to provide each of the Member country the means from which to render informed regulatory decisions for the benefit of public health and safety. Each organization had developed a questionnaire to gather information from Member countries on LPSD PSAs experiences. The responses cover a broad spectrum of LPSD PSA topics, and identifies work for improving risk-informed trade-off decisions, using PSA techniques, between LPSD and full power operational states. Each organization recognized potential benefit for improving the state-of-the-art by combining the wealth of experiences from the questionnaire responses into a common report. This report provides a summary of the current LPSD PSAs in Member countries, covering the elements which make up the PSAs. This report identifies the uses of the LPSD PSAs, summarizes current approaches, aspects, and good practices, identifies and defines differences between methods and data in full power and LPSD PSAs, and identifies guidance, methods, data, and basic research needs to address the differences. The responses to the questionnaires are provided in the Appendixes. The information contained in this report was gathered from two surveys, one by COOPRA and the other by WGRisk, which were performed over several years. Volume 2 of this report contains the responses from the CSNI / WGRisk Survey; Volume 3 contains the responses from the COOPRA Survey

IDENTIFICATION OF MEMBERS IN THE CENTRAL AND OUTER REGIONS OF GALAXY CLUSTERS

Serra, Ana Laura; Diaferio, Antonaldo

The caustic technique measures the mass of galaxy clusters in both their virial and infall regions and, as a byproduct, yields the list of cluster galaxy members. Here we use 100 galaxy clusters with mass M 200 ≥ 10 14 h –1 M ☉ extracted from a cosmological N-body simulation of a ΛCDM universe to test the ability of the caustic technique to identify the cluster galaxy members. We identify the true three-dimensional members as the gravitationally bound galaxies. The caustic technique uses the caustic location in the redshift diagram to separate the cluster members from the interlopers. We apply the technique to mock catalogs containing 1000 galaxies in the field of view of 12 h –1 Mpc on a side at the cluster location. On average, this sample size roughly corresponds to 180 real galaxy members within 3r 200 , similar to recent redshift surveys of cluster regions. The caustic technique yields a completeness, the fraction of identified true members, f c = 0.95 ± 0.03, within 3r 200 . The contamination, the fraction of interlopers in the observed catalog of members, increases from f i =0.020 +0.046 -0.015 at r 200 to f i =0.08 +0.11 -0.05 at 3r 200 . No other technique for the identification of the members of a galaxy cluster provides such large completeness and small contamination at these large radii. The caustic technique assumes spherical symmetry and the asphericity of the cluster is responsible for most of the spread of the completeness and the contamination. By applying the technique to an approximately spherical system obtained by stacking the individual clusters, the spreads decrease by at least a factor of two. We finally estimate the cluster mass within 3r 200 after removing the interlopers: for individual clusters, the mass estimated with the virial theorem is unbiased and within 30% of the actual mass; this spread decreases to less than 10% for the spherically symmetric stacked cluster.

Pharmacy and therapeutics (P&T) committees are responsible for managing drug formularies in numerous health care settings. Although pharmacy practice and health care organizations provide general recommendations of responsibilities and skills for members and nonmember contributors of P&T committees, the study investigators hypothesized that there is diversity in the training, responsibilities, and practices of these members and contributors. To describe the training, responsibilities, and practices of members and nonmember contributors of P&T committees in a variety of health care settings, using an online survey. In December 2015, an online survey was delivered to clinicians who were considered likely to be involved in P&T committee service from hospitals ranked by U.S. News & World Report and a convenience sample of clinicians practicing in managed care settings. The survey instrument was designed to assess various domains and perceptions of P&T committee processes. Sixty-nine respondents representing various health care delivery settings in the United States were eligible for and completed the survey. The majority of the respondents were pharmacists (94.2%), and 72.5% of the respondents were P&T committee members. The remainder of the respondents were nonmember P&T committee contributors. Approximately 60% of the respondents had served in P&T committee roles for ≥ 10 years. Specialized postgraduate training incorporating literature evaluation and formulary management was possessed by 21.7% and 17.4% of the respondents, respectively; however, most of the respondents received on-the-job training. Approximately half of the respondents were responsible for preparation of P&T committee documents, and 58% reported that nonmember contributors typically write and prepare these documents. Skill in literature evaluation was the most important criterion in selecting authors of P&T committee documents, while 10.1% of the respondents indicated that their committees did not

The Energy Efficiency and Renewable Energy Network (EREN) Customer Satisfaction Survey was developed and executed in support of EREN`s continuous quality improvement (CQI) plan. The study was designed to provide information about the demographic make up of EREN users, the value or benefits they derive from EREN, the kinds and quality of services they want, their levels of satisfaction with existing services, their preferences in both the sources of service and the means of delivery, and to provide benchmark data for the establishment of continuous quality improvement measures. The survey was performed by soliciting voluntary participation from members of the EREN Users Group. It was executed in two phases; the first being conducted by phone using a randomly selected group; and the second being conducted electronically and which was open to all of the remaining members of the Users Group. The survey results are described.

Assessment of role of metamorphic remobilization in genesis of uranium ores from Ralston Buttes area, Colorado

International Nuclear Information System (INIS)

Chatterjee, S.K.

1984-01-01

The Ralston Buttes mining district, the principal source of commercial uranium in the Front Range since the late 1940s, is located northeast of Golden and southeast of the Front Range mineral belt. Uranium ore occurs in veins emplaced in fault breccia in Precambrian metamorphic rocks. The progenitors of the metamorphic rocks are a possible source for the uranium. Hornblende gneisses of the Idaho Springs Formation is the major rock type in the area, thus its origin is a major consideration in assessing the quantity of uranium that might have been contributed by metamorphic processes. To evaluate this, 41 rock samples (19 hornblende gneisses, 7 biotite gneisses, 5 chlorite gneisses, and 10 metapelites) were analyzed for major elements, and 3 rock samples (16 hornblende gneisses, 8 biotite gneisses, 4 chlorite gneisses, and 5 mica schists) were analyzed for trace metals (Rb, Sc, Zr, V, Ni, Co, Cr, Ba, U, and Th). Four samples of hornblende gneiss and 1 sample of mica schists were also analyzed for rare earth elements. Major elements are rare earth data indicate that the hornblende gneiss was derived from sediments and tholeiitic basalts. Trace element data suggest a volcanic provenance for these sediments. Rare earth patterns and uranium and thorium abundances of metapelites are similar to average North American shales. Low uranium and thorium values and low thorium-uranium ratios in hornblende gneisses and mica schists preclude large-scale uranium remobilization during metamorphism of these source rocks

-II disorder (DSM IV criteria) was present in 11% of FA-OCD and 16% of PSY-OCD. Furthermore using the Hypomania Checklist showed that BP-II disorder rate (score > or = 10) was higher: 32% of in both populations. Cyclothymic rate was also globally higher, but significant difference was obtained: 56% of FA-OCD versus 45% of PSY-OCD (p = 0.02). Moreover, mood switching rate under anti-OCD drugs was equivalent in both OCD populations (respectively 38% and 33%, p = ns). In case of BP comorbidity, patients had presented a greater number of concurrent major depressive episodes and suicidal attempts. When concurrent depression was considered, the rate diagnosis of soft bipolarity was 2.5 fold, and the number of suicidal attempts augmented by 7 fold (by comparison versus non-depressed OCD). Despite very early descriptions (since the beginning of the last century) of particular relationships between so-called "psychasthenia, folie de doute, folie raisonnante" and "circular and intermittent madness or cyclothymia", a few attention has been devoted to this complex pattern of comorbidity. The comparative data deriving from the collaborative survey with patients who are members of AFTOC and with a cohort of psychiatric outpatients, confirm the reality of bipolar-OCD comorbidity, which is largely under-recognized in clinical practice. More in depth analyses are now undertaken in order to investigate the characteristics of "bipolar OCD" by comparison to "non bipolar OCD".

A growing number of online communities have been established to support those who self-harm. However, little is known about the therapeutic affordances arising from engagement with these communities and resulting outcomes. The aim of this study was to explore the presence of therapeutic affordances as reported by members of self-harm online support communities. In total, 94 respondents (aged 13-63 years, mean=23.5 years; 94% female) completed an online survey exploring their experiences of engaging with a self-harm online support community. Respondents varied in terms of how long they had been accessing an online community, with 22% (21/94) accessing less than 1 year, 39% (37/94) 1 to 2 years, 14% (13/94) 2 to 3 years, and 24.5% (23/94) more than 3 years. Responses were analyzed using deductive thematic analysis. The results of our analysis describe each of the five therapeutic affordances that were present in the data, namely (1) connection, the ability to make contact with others who self-harm for the purposes of mutual support and in so doing reduce feelings of loneliness and isolation; (2) adaptation, that is, how use of online support varies in relation to the personal circumstances of the individual user; (3) exploration, that is, the ability to learn about self-harm and learn about strategies to reduce or stop self-harming behavior; (4) narration, that is, the ability to share experiences, as well as read about the experiences of others; and (5) self-presentation, that is, how and what users present about themselves to others in the online community. Our findings suggest that engagement with self-harm online support communities may confer a range of therapeutic benefits for some users, which may serve to minimize the psychosocial burden of self-harm and promote positive coping strategies. In addition, the online nature of the support available may be helpful to those who are unable to access face-to-face support. ©Neil S Coulson, Emma Bullock, Karen Rodham

Laser welding input parameters play a very significant role in determining the quality of a weld joint. The joint quality can be defined in terms of properties such as weld bead geometry, mechanical properties and distortion. Therefore, mechanical properties should be controlled to obtain good welded joints. In this study, the weld bead geometry such as depth of penetration (DP), bead width (BW) and tensile strength (TS) of the laser welded butt joints made of AISI 904L super austenitic stainless steel were investigated. Full factorial design was used to carry out the experimental design. Artificial Neural networks (ANN) program was developed in MatLab software to establish the relationships between the laser welding input parameters like beam power, travel speed and focal position and the three responses DP, BW and TS in three different shielding gases (Argon, Helium and Nitrogen). The established models were used for optimizing the process parameters using Genetic Algorithm (GA). Optimum solutions for the three different gases and their respective responses were obtained. Confirmation experiment has also been conducted to validate the optimized parameters obtained from GA.

Lead exposure and blood lead levels (BLLs) in the United States have declined dramatically since the 1970s as many widespread lead uses have been discontinued. Large scale mining and mineral processing represents an additional localized source of potential lead exposure in many historical mining communities, such as Butte, Montana. After 25 years of ongoing remediation efforts and a residential metals abatement program that includes blood lead monitoring of Butte children, examination of blood lead trends offers a unique opportunity to assess the effectiveness of Butte's lead source and exposure reduction measures. This study examined BLL trends in Butte children ages 1-5 (n= 2796) from 2003-2010 as compared to a reference dataset matched for similar demographic characteristics over the same period. Blood lead differences across Butte during the same period are also examined. Findings are interpreted with respect to effectiveness of remediation and other factors potentially contributing to ongoing exposure concerns. BLLs from Butte were compared with a reference dataset (n=2937) derived from the National Health and Nutrition Examination Survey. The reference dataset was initially matched for child age and sample dates. Additional demographic factors associated with higher BLLs were then evaluated. Weights were applied to make the reference dataset more consistent with the Butte dataset for the three factors that were most disparate (poverty-to-income ratio, house age, and race/ethnicity). A weighted linear mixed regression model showed Butte geometric mean BLLs were higher than reference BLLs for 2003-2004 (3.48vs. 2.05µg/dL), 2005-2006 (2.65vs. 1.80µg/dL), and 2007-2008 (2.2vs. 1.72µg/dL), but comparable for 2009-2010 (1.53vs. 1.51µg/dL). This trend suggests that, over time, the impact of other factors that may be associated with Butte BLLs has been reduced. Neighborhood differences were examined by dividing the Butte dataset into the older area called "Uptown

Community health workers (CHWs) are members of a growing profession in the United States. Studying this dynamic labor force is challenging, in part because its members have more than 100 different job titles. The demand for timely, accurate information about CHWs is increasing as the profession gains recognition for its ability to improve health outcomes and reduce costs. Although numerous surveys of CHWs have been conducted, the field lacks well-delineated methods for gaining access to this hard-to-identify workforce. We outline methods for surveying CHWs and promising approaches to engage the workforce and other stakeholders in conducting local, state, and national studies. We also highlight successful strategies to overcome challenges in CHW surveys and future directions for surveying the field.

Full Text Available This study examined faculty members’ perceptions of blended teaching from several perspectives. A total of 73 faculty members in Turkish Higher Education context participated in the study by completing an online survey that combined quantitative and qualitative approaches. Based on a data analysis, the faculty members’ perceptions were sorted into six categories: (a satisfaction with blended teaching, (b perceived impact on the role of the faculty, (c perceived impact on student learning, (d perceived impact on student motivation, (e advantages of blended teaching, and (f disadvantages of blended teaching. Findings indicated that faculty members were likely to agree that blended teaching provides a high degree of satisfaction and that it requires more time and commitment from the faculty. The faculty members perceived that blended teaching improves student learning and, to some extent, improves motivation. The faculty members also emphasized the importance of institutional support and the use of technology to mitigate student problems. This study presents these faculty members’ perceptions, which are helpful for those planning to implement a blended teaching approach, and makes suggestions for trouble-shooting and taking advantage of the opportunities in a blended environment successfully.

In order to create safe, healthy and wealthy places to live in, it is vital that we understand our planet. At national level the collection of information on the state of the solid Earth and its processes is normally mandated to Geological Surveys. In fact, a Geological Survey is the national institution responsible for the geological inventory, monitoring, knowledge and research for the security, health and prosperity of the society. And EuroGeoSurveys (EGS) is the organisation representing the Geological Surveys from 33 countries around Europe. With one member for each country of the European Union and beyond, including the Russian Federation and Ukraine, the EGS network covers the whole continent. EGS'principal purpose is to provide geoscientific knowledge that underpins European policies and regulations for the benefit of society. Naturally, in our day-to-day activities, we contribute to the merging of economic, environmental and social agendas. Engaging a joint workforce of several thousands of geoscientists, also involving regional geological surveys in Germany, Italy and Spain, we strive to be the first body to be contacted when there is an international need for European geodata, or'geo-help'. For this reason we work on a daily basis with the EU institutions, and are considered the natural source of information on Earth science issues and relevant downstream applications in Europe. Our General Secretariat is based in the European Quarter of Brussels close to the European Commission, the EU Council, the European Parliament, and the political seat of NATO. Our operational strategy is based on the cooperation between national institutions, which enables to synergistically integrate both information and activities of our member organisations. This has allowed us to make significant progress over the years, permitting geology to become a topic deserving great attention on the European agenda.

Introduction: According to the Royal College objectives of training in urology, urologic surgical procedures are divided as category A, B and C. We wanted to determine the level of proficiency required and achieved by urology training faculty for Royal College accreditation. Methods: We conducted a survey that was sent electronically to all Canadian urology training faculty. Questions focused on demographics (i.e., years of practice, geographic location, subspecialty, access to robotic surgery), operating room contact with residents, opinion on the level of proficiency required from a list of 54 surgical procedures, and whether their most recent graduates attained category A proficiency in these procedures. Results: The response rate was 43.7% (95/217). Among respondents, 92.6% were full timers, 21.1% practiced urology for less than 5 years and 3.2% for more than 30 years. Responses from Quebec and Ontario formed 69.4% (34.7% each). Of the respondents, 37.9% were uro-oncologists and 75.7% reported having access to robotic surgery. Sixty percent of faculty members operate with R5 residents between 2 to 5 days per month. When respondents were asked which categories should be listed as category A, only 8 procedures received 100% agreement. Also, results varied significantly when analyzed by sub-specialty. For example, almost 50% or more of uro-oncologists believed that radical cystectomy, anterior pelvic exenteration and extended pelvic lymphadenectomy should not be category A. The following procedures had significant disagreement suggesting the need for re-classification: glanular hypospadias repair, boari flap, entero-vesical and vesicovaginal fistulae repair. Overall, more than 80% of faculty reported that their recent graduating residents had achieved category A proficiency, in a subset of procedures. However, more than 50% of all faculty either disagreed or were ambivalent that all of their graduating residents were Category A proficient in several procedures

The geometry of the weld beads is characterized by the overhead, the width and the penetration. These values are indices of the behavior of the welded joint and therefore, they can be considered as factors that control the process. This work is performed to optimize the GMAW process of the aluminum alloy AA 6063-T5 by means of the response surface methodology (RSM). The variables herein considered are the arc voltage, the welding speed, the wire feed speed and the separation between surfaces in butt joints. The response functions that are herein studied are the overhead, the width, the penetration and the angle of the bead. The obtained results by RSM show high grade of agreement with the experimental values. The procedure is experimentally validated by welding for the theoretically obtained optimized technological conditions and a wide agreement between theoretical and experimental values is found.

Biodiversity conservation is a required co-benefit of REDD+. Biodiversity monitoring is therefore needed, yet in most areas it will be constrained by limitations in the available human professional and financial resources. REDD+ programs that use forest plots for biomass monitoring may be able to take advantage of the same data for detecting changes in the tree diversity, using the richness and abundance of canopy trees as a proxy for biodiversity. If local community members are already assessing the above-ground biomass in a representative network of forest vegetation plots, it may require minimal further effort to collect data on the diversity of trees. We compare community members and trained scientists' data on tree diversity in permanent vegetation plots in montane forest in Yunnan, China. We show that local community members here can collect tree diversity data of comparable quality to trained botanists, at one third the cost. Without access to herbaria, identification guides or the Internet, community members could provide the ethno-taxonomical names for 95% of 1071 trees in 60 vegetation plots. Moreover, we show that the community-led survey spent 89% of the expenses at village level as opposed to 23% of funds in the monitoring by botanists. In participatory REDD+ programs in areas where community members demonstrate great knowledge of forest trees, community-based collection of tree diversity data can be a cost-effective approach for obtaining tree diversity information.

To explore the ageing stereotypes held by health students and faculty members in three health science schools in Chile. This cross-sectional study surveyed 284 students and faculty members from the dental, physical therapy and speech therapy schools of the University of Talca, Chile. A validated 15-question questionnaire about negative stereotypes was used (CENVE). The questions were divided into three categories: (i) health, (ii) social factors and motivation and (iii) character and personality. The scores for each category were grouped into the following categories: (i) positive, (ii) neutral and (iii) negative. Negative stereotypes were compared across genders, socio-economic status levels, classes, positions (student or faculty member) and schools. The majority of the participants held neutral stereotypes towards ageing, followed by positive perceptions. No differences were detected between the genders, schools or classes. While most of the students had neutral perceptions about ageing, the faculty's perceptions were rather positive (p = 0.0182). In addition, people of lower-middle socio-economic status held more positive stereotypes about ageing than the participants of high and middle status (p = 0.0496). Stereotypes about ageing held by health-related students and faculty members appear to be rather neutral. The stereotypes seem to be better among students with some clinical experience, students of lower socio-economic status and faculty members. © 2013 John Wiley & Sons A/S and The Gerodontology Society.

We began with the newly assembled catalog of literature lithium measurements reported by Barrado et al. (2016, J/A+A/596/A113), who accepted only stars with membership probability >0.75. A small number of Pleiads lie behind an HI cloud, and are thus far more extincted than the rest (e.g., Gordon & Arny 1984AJ.....89..672G); for simplicity, we discard these members. We then cross-correlated this sample with the famous UBV photometric catalog of Johnson & Mitchell (1958ApJ...128...31J), who produced homogeneous photometry for a large sample of Pleiades members. We further selected stars with measured rotation rates, either from the HATNet collaboration (Hartman et al. 2010, J/MNRAS/408/475), or the recent analysis of K2 data (Rebull et al. 2016, J/AJ/152/113, J/AJ/152/114; Stauffer et al. 2016, J/AJ/152/115), preferring the latter for joint detections. Finally, we queried VizieR (http://vizier.u-strasbg.fr/) to obtain KS-band magnitudes from the Two-Micron All-Sky Survey (2MASS) catalog (Skrutskie et al. 2006, Cat. VII/233), which detected every star in our reduced sample. These criteria produced a total of 83 high-probability cluster members, stretching from early-F to late-K type. (3 data files).

Full Text Available Introduction: The research considers safety climate in a warehouse and wants to analyze the Leader–Member Exchange (LMX role in respect to safety performance. Griffin and Neal’s safety model was adopted and Leader-Member Exchange was inserted as moderator in the relationships between safety climate and proximal antecedents (motivation and knowledge of safety performance constructs (compliance and participation.Materials and Methods: Survey data were collected from a sample of 133 full-time employees in an Italian warehouse. The statistical framework of Hayes (2013 was adopted for moderated mediation analysis.Results: Proximal antecedents partially mediated the relationship between Safety climate and safety participation, but not safety compliance. Moreover, the results from the moderation analysis showed that the Leader–Member Exchange moderated the influence of safety climate on proximal antecedents and the mediation exist only at the higher level of LMX.Conclusion: The study shows that the different aspects of leadership processes interact in explaining individual proficiency in safety practices.Practical Implications: Organizations as warehouses should improve the quality of the relationship between a leader and a subordinate based upon the dimensions of respect, trust, and obligation for high level of safety performance.

Public Attitudes towards Monetary Integration in Seven New Member States of the EU

Szőcs Csongor-Ernő

2015-04-01

Full Text Available Existing work on euro support has provided insights into the dynamics of preferences, but most of these studies focus on older member states that already form an integral part of the Eurozone. This article inquires into public attitudes towards monetary integration in new member states of the EU: Poland, the Czech Republic, Romania, Hungary, Croatia, Bulgaria and Lithuania. Focusing on the cross-sectional variation of preferences, it applies multilevel logit regression to test three perspectives – economic, conceptual and political – using individual-level survey data and NUTS-2 regional statistical data from seven countries for 2013. One of its novel findings is that beliefs such as the one that European Monetary Union (EMU adherence will cause a spiral in economic inflation are powerful disincentives to euro support in these countries.

To ascertain-1) the prevalence of depression and psychosocial characteristics in alcoholics who are members of teetotal societies, and 2) the relationship between depression and psychosocial factors. A self-report questionnaire survey was conducted of 184 alcoholic members of seven teetotal societies in a prefecture in Japan. Questionnaires consisted of items on demographics, the self-rating depression scale (SDS), family environment in childhood, self-esteem, coping, and sense of coherence (SOC). 1) The mean SDS score was 31.8 points in males and 35.8 points in females. Depression level for the male sample was equivalent to that for male employees. Coping behavior characterized by escape and resignation was more prevalent in the employees. Mean scores of both self-esteem (33.3 points) and SOC (118.7 points) were lower than in general. 2) SDS was significantly related to length of time spent within a teetotal society, self-esteem, SOC, coping behavior characterized by resignation and positive approaches to problem solving. The shorter the time within the teetotal society, the lower the scores for self-esteem, SOC, and coping behavior typified by positive approaches to problem solving; and the higher the score for coping behavior characterized by resignation, the higher the SDS score. The findings of this study suggested that depression in alcoholic members of teetotal societies occurred at similar levels to that for the general population, but that self-esteem, sense of coherence, and suitable coping behaviors were reduced. It was suggested that depression in alcoholics who are members of teetotal societies may be associated with short history of membership in the group, low sense of coherence, low self-esteem, and inappropriate coping behavior.

  Evaluations of faculty members are widely used to identify excellent or substandard teaching performance. In order to enable such evaluations to be properly interpreted and used in faculty development, it is essential to understand the factors that influence resident doctors' (residents) evaluations of the teaching qualities of faculty members and their perceptions of faculty members as role-model specialists.   We carried out a cross-sectional survey within a longitudinal study of the System for Evaluation of Teaching Qualities (SETQ) of clinical teachers. The study sample included 889 residents and 1014 faculty members in 61 teaching programmes spanning 22 specialties in 20 hospitals in the Netherlands. Main outcome measures included residents' (i) global and (ii) specific ratings of faculty member teaching qualities, and (iii) global ratings of faculty members as role-model specialists. Statistical analysis was conducted using adjusted multivariable logistic generalised estimating equations.   In total, 690 residents (77.6%) completed 6485 evaluations of 962 faculty members, 848 (83.6%) of whom also self-evaluated. More recently certified faculty members, those who had attended a teacher training programme, and those who spent more time teaching than seeing patients or conducting research were more likely to score highly on most teaching qualities. However, faculty members who had undergone teacher training were less likely to be seen as role models (odds ratio [OR] 0.72, 95% confidence interval [CI] 0.59-0.88). In addition, faculty members were evaluated slightly higher by male than female residents on core teaching domains and overall teaching quality, but were less likely to be seen as role models by male residents (OR 0.80, 95% CI 0.67-0.97). Lastly, faculty members had higher odds of receiving top scores in specific teaching domains from residents in the first 4 years of residency and were less likely to be considered as role models by more

Full Text Available Fibreoptic intubation, high frequency jet ventilation, and videolaryngoscopy form part of the Royal College of Anaesthetists compulsory higher airway training module. Curriculum delivery requires equipment availability and competent trainers. We sought to establish (1 availability of advanced airway equipment in UK hospitals (Survey I and (2 if those interested in airway management (Difficult Airway Society (DAS members had access to videolaryngoscopes, their basic skill levels and teaching competence with these devices and if they believed that videolaryngoscopy was replacing conventional or fibreoptic laryngoscopy (Survey II. Data was obtained from 212 hospitals (73.1% and 554 DAS members (27.6%. Most hospitals (202, 99% owned a fiberscope, 119 (57.5% had a videolaryngoscope, yet only 62 (29.5% had high frequency jet ventilators. DAS members had variable access to videolaryngoscopes with Airtraq 319 (59.6% and Glidescope 176 (32.9% being the most common. More DAS members were happy to teach or use videolaryngoscopes in a difficult airway than those who had used them more than ten times. The majority rated Macintosh laryngoscopy as the most important airway skill. Members rated fibreoptic intubation and videolaryngoscopy skills equally. Our surveys demonstrate widespread availability of fibreoptic scopes, limited availability of videolaryngoscopes, and limited numbers of experienced videolaryngoscope tutors.

To assess the opinion on structured reporting (SR) and its usage by radiologist members of the Italian Society of Medical Radiology (SIRM) via an online survey. All members received an email invitation to join the survey as an initiative by the SIRM Imaging Informatics Chapter. The survey included 10 questions about demographic information, definition of radiological SR, its usage in everyday practice, perceived advantages and disadvantages over conventional reporting and overall opinion about SR. 1159 SIRM members participated in the survey. 40.3 % of respondents gave a correct definition of radiological SR, but as many as 56 % of them never used it at work. Compared with conventional reporting, the most appreciated advantages of SR were higher reproducibility (70.5 %), better interaction with referring clinicians (58.3 %) and the option to link metadata (36.7 %). Risk of excessive simplification (59.8 %), template rigidity (56.1 %) and poor user compliance (42.1 %) were the most significant disadvantages. Overall, most respondents (87.0 %) were in favour of the adoption of radiological SR. Most radiologists were interested in radiological SR and in favour of its adoption. However, concerns about semantic, technical and professional issues limited its diffusion in real working life, encouraging efforts towards improved SR standardisation and engineering. (orig.)

We conducted a survey of member facilities of the Japan Society of Ningen Dock to elucidate the actual status of chest computed tomography (CT) screening and the reasons for not being able to change to low-dose CT. We sent a questionnaire consisting of 9 items to 531 member facilities in July 2010, response by facsimile to obtain an analysis. The prevalence rate of low-dose CT lung cancer screening slightly increased to 35% in comparison with the former survey done in November 2008. Some facilities indicated some shift in tube current to a lower range even though this was insufficient to meet the definition of low-dose CT. This reflects their thinking of ''Even with knowledge, there is strong hesitation to change to low-dose CT''. Among the reasons why they did not change to low-dose CT, a priority for high quality images was the top reason among problems of devices and performance. Informed consent was not yet adequate. It is necessary for manufactures to develop better technology to improve the image quality of low-dose CT and to report enough information to clinicians. On the medical side, perception of the necessity for appropriate reduction of radiation dose and the decision to move to low-dose CT would be of crucial significance for facility heads as well as radiologists and technicians.

Report on the Survey on Regulation of Site Selection and Preparation

International Nuclear Information System (INIS)

Webster, Philip

2010-01-01

At its first meeting in May 2008, the Working Group discussed a task to 'Prepare a report reviewing the various practices used by regulators in the regulation of nuclear power plant siting. The report should consider regulator practices on sites where a mixture of activities are taking place (e.g. operating units, new construction, decommissioning, etc) including organization of the regulators organisation, methods, systems, etc.'. Following discussion, the Working Group assigned an Action 1-5 to 'develop a survey on the regulation of nuclear sites including seismicity issues, security issues, multi-units aspects and regulator practices on sites where a mixture of activities are taking place (e.g. operating units, new construction, decommissioning, etc.)'. The Survey was prepared and issued by the NEA in July 2008 with a request to the member states to provide their responses by the next meeting of the Working Group in October 2008. In addition to addressing the specific topics actioned by the Working Group, the Survey also investigated the broader context of siting, in order to address the Mandate that had been approved by the CNRA. The questions in the survey therefore covered the topics of site evaluation, site selection, regulatory approval, site preparation and regulatory oversight. A topic of particular interest was to what extent IAEA guidance on site evaluation was followed. The survey considered the possibility that a body other than the safety regulator may approve the choice of site or permit the applicant to start to prepare it. The survey also investigated the existence of formal requirements and informal expectations, recognizing that these both form part of the regulatory tool-kit. Responses were received from all twelve member states that were then members of the Working Group. The responses were reviewed at the second meeting of the Working Group in October 2008. In general, it could be stated that new reactors are licensed in

Plainly, part-time/adjunct faculty members now play a vital role in educating the nation's college students. Even so, the data and research on part-time/adjunct faculty members have tended to be pretty spotty. This survey, conducted by Hart Research Associates on behalf of the American Federation of Teachers, is one of the first nationwide…

Little is known about the differences between gang members and gang affiliates-or those individuals who associate with gangs but are not gang members. Even less is known about how these groups compare with other violent populations. This study examined how gang members, gang affiliates, and violent men compare on mental health symptoms and traumatic experiences. Data included a sample of 1,539 adult males, aged 19 to 34 years, taken from an earlier survey conducted in the United Kingdom. Participants provided informed consent before completing questionnaires and were paid £5 for participation. Logistic regression analyses were conducted to compare participants' symptoms of psychiatric morbidity and traumatic event exposure. Findings showed that, compared to violent men and gang affiliates, gang members had experienced more severe violence, sexual assaults, and suffered more serious/life-threatening injuries. Compared to violent men, gang members and gang affiliates had made more suicide attempts; had self-harmed more frequently; and had experienced more domestic violence, violence at work, homelessness, stalking, and bankruptcy. Findings further showed a decreasing gradient from gang members to gang affiliates to violent men in symptom levels of anxiety, antisocial personality disorder, pathological gambling, stalking others, and drug and/or alcohol dependence. Depression symptoms were similar across groups. The identified relationship between gang membership, affiliation, and adverse mental health indicates that mental health in gang membership deserves more research attention. Findings also indicate that criminal justice strategies need to consider gang members' mental health more fully, if gang membership is to be appropriately addressed and reduced.

To identify characteristics and quality indicators of best practices for leadership and advocacy development in pharmacy education, a national task force on leadership development in pharmacy invited colleges and schools to complete a phone survey to characterize the courses, processes, and noteworthy practices for leadership and advocacy development at their institution. The literature was consulted to corroborate survey findings and identify additional best practices. Recommendations were derived from the survey results and literature review, as well as from the experience and expertise of task force members. Fifty-four institutions provided information about lecture-based and experiential curricular and noncurricular components of leadership and advocacy development. Successful programs have a supportive institutional culture, faculty and alumni role models, administrative and/or financial support, and a cocurricular thread of activities. Leadership and advocacy development for student pharmacists is increasingly important. The recommendations and suggestions provided can facilitate leadership and advocacy development at other colleges and schools of pharmacy. PMID:24371344

Geologic map of the Strawberry Butte 7.5’ quadrangle, Meagher County, Montana

Reynolds, Mitchell W.; Brandt, Theodore R.

2017-06-19

The 7.5′ Strawberry Butte quadrangle in Meagher County, Montana near the southwest margin of the Little Belt Mountains, encompasses two sharply different geologic terranes.  The northern three-quarters of the quadrangle are underlain mainly by Paleoproterozoic granite gneiss, across which Middle Cambrian sedimentary rocks rest unconformably.  An ancestral valley of probable late Eocene age, eroded northwest across the granite gneiss terrane, is filled with Oligocene basalt and overlying Miocene and Oligocene sandstone, siltstone, tuffaceous siltstone, and conglomerate.  The southern quarter of the quadrangle is underlain principally by deformed Mesoproterozoic sedimentary rocks of the Newland Formation, which are intruded by Eocene biotite hornblende dacite dikes.  In this southern terrane, Tertiary strata are exposed only in a limited area near the southeast margin of the quadrangle.  The distinct terranes are juxtaposed along the Volcano Valley fault zone—a zone of recurrent crustal movement beginning possibly in Mesoproterozoic time and certainly established from Neoproterozoic–Early Cambrian to late Tertiary time.  Movement along the fault zone has included normal faulting, the southern terrane faulted down relative to the northern terrane, some reverse faulting as the southern terrane later moved up against the northern terrane, and lateral movement during which the southern terrane likely moved west relative to the northern terrane.  Near the eastern margin of the quadrangle, the Newland Formation is locally the host of stratabound sulfide mineralization adjacent to the fault zone; west along the fault zone across the remainder of the quadrangle are significant areas and bands of hematite and iron-silicate mineral concentrations related to apparent alteration of iron sulfides.  The map defines the distribution of a variety of surficial deposits, including the distribution of hematite-rich colluvium and iron-silicate boulders.  The southeast

A complex tracer mixture was injected continuously for over two years into a 10 x 10 x 7 m block of tuff as part of the unsaturated-zone (UZ) tracer test at Busted Butte. The test was designed to address uncertainties associated with flow and transport models within the Topopah Springs and Calico Hills tuffs. The tracer mixture included nonreactive (Br, I, and FBAs) and reactive tracers (Li, Ce, Sm, Ni, Coy and Mn) and synthetic colloids. Once injection was completed, samples from the block were collected in two ways. Overcores were taken from around and below injection holes. Then, the entire block was excavated via mineback--during which progressive vertical planes of the block were exposed. Samples from the overcores and mineback were analyzed to determine the distribution of tracers on different spatial scales than available from collection borehole data. Rock analyses confirmed collection pad results that the nonreactive tracers, Br and FBAs, moved several meters. Furthermore, Br and FBAs are observed above and lateral to the injector planes suggesting that capillarity was an important process for tracer movement. Lithium, the most mobile of the metals, was transported on a scale of meters. This is consistent with laboratory sorption measurements and observed breakthrough on the collection pads. Co and Ni show transport distances of tens of cm, while Sm and Ce moved far less, possibly due to precipitation and sorption effects. Colloid transport was assessed using 1 ft3 blocks extracted from the BB Phase 2 block. In the Calico Hills material, after 15 L of water was injected over 3.5 months, less than 1% of the colloids injected were recovered. Flow patterns in the block indicate that water injected at the center imbibed outward from the injection point. In a block taken from a boundary of the Calico Hills ashfall layer, breakthrough was observed only due to fractures formed during drying of the block. The colloid transport module for FEHM was tested against
