In colorectal cancer surgery, inadvertent deep injections during endoscopic tattooing can cause India ink leakage into the peritoneum, leading to complications or to poor visualization of the surgical plane. This ex vivo animal study compared the use of novel shorter, minimum caliber needles versus conventional injection needles for endoscopic tattooing. Four endoscopists used the novel needles and conventional needles to make ten endoscopic tattoos (five tattoos/needle type/endoscopist) in harvested porcine rectum using a saline test-injection method. India ink leakage and the success of the tattoo (i. e. visible, tattoos but for none of the novel needle tattoos ( P  = 0.02). Tattoos created using the novel needles were more successful than those made with the conventional needles: 18/20 (90 %) vs. 11/20 (55 %); P  = 0.01. The use of novel shorter minimum caliber needles may be safe and effective for endoscopic tattooing for preoperative localization prior to colorectal cancer surgery.

Duan, Zhongyan

This paper, under 3-using principle in the philosophy of caliber-oriented education to success (CETS), makes a tentative qualitative study on the application of task-based approach in the teaching of English-Chinese translation based on the web. Translation teaching is characterized by its practicality. Therefore, the task-based approach can be employed to guide the web-based content collection and the process of English translation teaching. In this way, the prospect for enhancing student's translation ability is quite encouraging, which has been verified by one year's teaching.

Inferential methods can be used to integrate experimental informations and molecular simulations. The maximum entropy principle provides a framework for using equilibrium experimental data, and it has been shown that replica-averaged simulations, restrained using a static potential, are a practical and powerful implementation of such a principle. Here we show that replica-averaged simulations restrained using a time-dependent potential are equivalent to the principle of maximum caliber, the dynamic version of the principle of maximum entropy, and thus may allow us to integrate time-resolved data in molecular dynamics simulations. We provide an analytical proof of the equivalence as well as a computational validation making use of simple models and synthetic data. Some limitations and possible solutions are also discussed.

We review here Maximum Caliber (Max Cal), a general variational principle for inferring distributions of paths in dynamical processes and networks. Max Cal is to dynamical trajectories what the principle of maximum entropy is to equilibrium states or stationary populations. In Max Cal, you maximize a path entropy over all possible pathways, subject to dynamical constraints, in order to predict relative path weights. Many well-known relationships of non-equilibrium statistical physics-such as the Green-Kubo fluctuation-dissipation relations, Onsager's reciprocal relations, and Prigogine's minimum entropy production-are limited to near-equilibrium processes. Max Cal is more general. While it can readily derive these results under those limits, Max Cal is also applicable far from equilibrium. We give examples of Max Cal as a method of inference about trajectory distributions from limited data, finding reaction coordinates in bio-molecular simulations, and modeling the complex dynamics of non-thermal systems such as gene regulatory networks or the collective firing of neurons. We also survey its basis in principle and some limitations.

To evaluate the relationship between retinal vascular caliber (RVC), iris color, and age-related macular degeneration (AMD) in elderly Irish nuns. Data from 1233 participants in the cross-sectional observational Irish Nun Eye Study were assessed from digital photographs with a standardized protocol using computer-assisted software. Macular images were graded according to the modified Wisconsin Age-related Maculopathy Grading System. Regression models were used to assess associations, adjusting for age, mean arterial blood pressure, body mass index, refraction, and fellow RVC. In total, 1122 (91%) participants had gradable retinal images of sufficient quality for vessel assessment (mean age: 76.3 years [range, 56-100 years]). In an unadjusted analysis, we found some support for a previous finding that individuals with blue iris color had narrower retinal venules compared to those with brown iris color (P < 0.05), but this was no longer significant after adjustment. Age-related macular degeneration status was categorized as no AMD, any AMD, and late AMD only. Individuals with any AMD (early or late AMD) had significantly narrower arterioles and venules compared to those with no AMD in an unadjusted analysis, but this was no longer significant after adjustment. A nonsignificant reduced risk of any AMD or late AMD only was observed in association with brown compared to blue iris color, in both unadjusted and adjusted analyses. Retinal vascular caliber was not significantly associated with iris color or early/late AMD after adjustment for confounders. A lower but nonsignificant AMD risk was observed in those with brown compared to blue iris color. Copyright 2015 The Association for Research in Vision and Ophthalmology, Inc.

Although complex, inconsistent and fickle, the time-averaged flow over a stationary slender forebody is generally well-understood. However, the nature of unsteady, time-varying flows over slender forebodies - whether due to the natural unsteadiness or forced maneuvering - is not well-understood. This body of work documents three experimental investigations into the unsteadiness of the flow over a 3.5 caliber tangent-ogive cylinder at high angles of incidence.

Full Text Available Gamification, understood as a use of chosen game mechanisms for motivating actors in non-game contexts, is increasingly popular and has become one of the “hot topics” of managerial practice and science. Despite its widespread use in HRM, several barriers preventing its progress in certain types of organizations have been identified. Small and medium enterprises (SMEs, where employees are not accustomed to formal procedures are a specific example, as gamification is based on formal procedures. The goal of the text is to analyze employees’ opinions concerning the incorporation of chosen gaming mechanisms into their motivation systems, to check if not being accustomed to formal procedures is a barrier. Beside “typical” SMEs where the entrepreneur is present, direct relations within a team are also characteristic of company departments which achieve their goals almost without contact with the rest of the organization – as in the case of a discount stores chain. The study bases on two samples to check if being accustomed to formal procedures in the small team facilitates acceptance of gamification. Two questionnaires (one on a sample of 100 employees of a discount store chain, and the second on 73 “typical” SME employees asked respondents to declare their preferences for different types of rewards in motivation systems, including readiness to be involved in two gamification-type solutions: based on (i lotteries, or (ii BLAP gaming with non-material and material prizes. The effects of chosen factors: psychological (risk aversion and situational (dissatisfaction with current incentive system on the perception of two different ways of incorporating gamification into motivational systems, were analyzed. The results show that dissatisfaction with the current incentive system and not being risk-averse favor accepting the incorporation of gamification solutions into motivational systems. The responses of discount store employees and SME

Full Text Available The normal penetration of armor-piercing projectiles into single and multi-layered steel plates has been investigated. An experimental program has been conducted to study the effect of spaced and in-contact layered targets on their ballistic resistance. Armor piercing projectiles with caliber of 7.62 mm were fired against a series of single and multi-layered steel targets. The projectile impact velocities were ranged from 300-600 m/s, whereas the total thicknesses of the tested single, spaced and in-contact layered steel targets were 3 mm. The penetration process of different tested target configurations has been simulated using Autodayn-2D hydrocode. The experimental measurements of the present work were used to discuss the effect of impact velocity, target configurations and number of layers of different spaced and in-contact layered steel targets on their ballistic resistance. In addition, the post-firing examination of the tested targets over the used impact velocity range showed that the single and each layer of spaced and in-contact laminated steel targets were failed by petalling. Finally, the obtained experimental measurements were compared with the corresponding numerical results of Autodyn-2D hydrocode, good agreement was generally obtained.

We report the results of intra-arterial digital subtraction angiography (DSA) in 100 patients with portal hypertension. The portal venous system was evaluated; all patients underwent angiography of the celiac and superior mesenteric arteries before surgery. Forty-four of them were also examined after Warren splenorenal shunts. Therefore, a total of 144 exams was evaluated. The authors always employed low-osmolality ionic and non-ionic contrast media (iodine concentration: 300-350 mg/ml). In 70 cases pure contrast medium was injected (20/25 ml): in the extant 74 cases it was diluted with an equal volume of saline solution (osmolality and iodine concentration reduced by 50%). Intra-arterial DSA always visualized portal venous system, collateral circulation, shunt location and postoperative changes. The mayor advantage of intra-arterial DSA is the smaller amount of contrast medium injected, so that local and systemic side effects are rare. According to our experience, it is best to dilute the contrast medium and inject the same amount as in conventional angiography, at the same rate. Other well-known advantages of intra-arterial DSA are quicker execution, less injury to arteries using smaller caliber catheters, and low cost. The major disadvantage of intra-arterial DSA, as it appeared also in our study, is the field size of the intensifier, which in our case was limited to 6-9 inches. This is an insufficient coverage for the whole portal system to be studied, and some contrast medium injections become therefore necessary. An average of 3 injections were given to each patient. This problem reduces the advantage of less contrast medium per injection. At any rate, even though intra-arterial DSA exhibits this limitation, it can nevertheless yield important information in the pre- and postoperative evaluation of patients with portal hypertension

Forecasting the impact of an 1859-caliber superstorm on geosynchronous Earth-orbiting satellites: Transponder resources

We calculate the economic impact on the existing geosynchronous Earth-orbiting satellite population of an 1859-caliber superstorm event were it to occur between 2008 and 2018 during the next solar activity cycle. From a detailed model for transponder capacity and leasing, we have investigated the total revenue loss over the entire solar cycle, as a function of superstorm onset year and intensity. Our Monte Carlo simulations of 1000 possible superstorms, of varying intensity and onset year, suggest that the minimum revenue loss could be of the order of 30 billion. The losses would be larger than this if more that 20 satellites are disabled, if future launch rates do not keep up with the expected rate of retirements, or if the number of spare transponders falls below ˜30%. Consequently, revenue losses can be significantly reduced below 30 billion if the current satellite population undergoes net growth beyond 300 units during Solar Cycle 24 and a larger margin of unused transponders is maintained.

Despite improvements in sanitation and water supply, cholera remains a serious public health burden. Vaccination is included among recommendations for cholera control. Cultural concepts of illness are likely to affect vaccine acceptance. This study examined social and cultural determinants of anticipated acceptance of an oral cholera vaccine (OCV) prior to a mass vaccination campaign in Zanzibar. Using a cultural epidemiological approach, 356 unaffected adult residents were studied with vignette-based semi-structured interviews. Anticipated acceptance was high for a free OCV (94%), but declined with increasing price. Logistic regression models examined social and cultural determinants of anticipated acceptance at low (USD 0.9), medium (USD 4.5) and high (USD 9) price. Models including somatic symptoms (low and high price), social impact (low and medium) and perceived causes (medium and high) explained anticipated OCV acceptance better than models containing only socio-demographic characteristics. Identifying thirst with cholera was positively associated with anticipated acceptance of the low-priced OCV, but acknowledging the value of home-based rehydration was negatively associated. Concern about spreading the infection to others was positively associated at low price among rural respondents. Confidence in the health system response to cholera outbreaks was negatively associated at medium price among peri-urban respondents. Identifying witchcraft as cause of cholera was negatively associated at medium and high price. Anticipated acceptance of free OCVs is nearly universal in cholera-endemic areas of Zanzibar; pre-intervention assessments of community demand for OCV should not only consider the social epidemiology, but also examine local socio-cultural features of cholera-like illness that explain vaccine acceptance.

Full Text Available Fast progress of information-communication technology, distribution of computer networks and wider usage of Internet are basis for the new industrial revolution. Therefore, e-commerce presents new possibility of gathering competitive advantages on the world market, especially for small and medium companies. In order to determine the current stage of electronic readiness and electronic intensity of using the e-commerce in small and medium companies in Croatia, there was a research carried through micro, small and medium companies on national level. Although the acceptance of Internet technologies and implementation of e-commerce ensures to small and medium companies to compete on the world market with large companies and to have efective infuence on their growth and development, the research showed that Croatian micro, small and medium companies, despite of their high level of electronic readiness and implementation of modern information-communication technologies, are not favorable in their usage in everyday business. It is necessary to figure out the universal model to remove barriers for implementation and acceptance of e-commerce.

Gun buyback programs aim to remove unwanted firearms from the community with the goal of preventing firearm injury and death. Buyback programs are held in many communities, but evidence demonstrating their effectiveness is lacking. The purpose of this study is to compare firearms collected at buyback events to crime guns and firearms used in homicides and suicides. Detailed firearm and case data were obtained from the Hartford Police Department and the Office of the Chief Medical Examiner from January through December of 2015. Information was reviewed for guns collected at buyback events, crime guns confiscated by police, and for weapons associated with firearm fatalities. Detailed firearm data included type, manufacturer, model, and caliber (small, ≤ 0.32 caliber; medium, 0.357 caliber to 9 mm; large, ≥ 0.40 caliber). χ analyses were used for comparisons between groups. In 2015, 224 crime guns were seized by the Hartford Police, 169 guns were collected at four community buyback events, and there were 187 firearm-related deaths statewide (105 suicides, 81 homicides, 1 legal intervention). Comparisons between buyback, crime, and fatality-related firearms are shown in the table below. Medium caliber handguns account for the majority of crime guns and fatalities, and buyback programs collected smaller caliber handguns. The demographics of individuals who turn in guns at buyback events and commit suicide are similar: age (buyback, 63 ± 11; suicide, 52 ± 18; homicide, 34 ± 12 years), sex (buyback, 81%; suicide, 91%; homicide, 84% men), and race (buyback, 80%; suicide, 97%; homicide, 47% white). Handguns account for the majority of crime guns and firearm-related fatalities in Connecticut. Buyback programs are both an opportunity to remove unwanted handguns from the community and to remove firearms from the homes of individuals at increased risk of suicide.

Tanaka, Leonardo Y; Laurindo, Francisco R M

2017-08-01

Vascular remodeling, i.e. whole-vessel structural reshaping, determines lumen caliber in (patho)physiology. Here we review mechanisms underlying vessel remodeling, with emphasis in redox regulation. First, we discuss confusing terminology and focus on strictu sensu remodeling. Second, we propose a mechanobiological remodeling paradigm based on the concept of tensional homeostasis as a setpoint regulator. We first focus on shear-mediated models as prototypes of remodeling closely dominated by highly redox-sensitive endothelial function. More detailed discussions focus on mechanosensors, integrins, extracellular matrix, cytoskeleton and inflammatory pathways as potential of mechanisms potentially coupling tensional homeostasis to redox regulation. Further discussion of remodeling associated with atherosclerosis and injury repair highlights important aspects of redox vascular responses. While neointima formation has not shown consistent responsiveness to antioxidants, vessel remodeling has been more clearly responsive, indicating that despite the multilevel redox signaling pathways, there is a coordinated response of the whole vessel. Among mechanisms that may orchestrate redox pathways, we discuss roles of superoxide dismutase activity and extracellular protein disulfide isomerase. We then discuss redox modulation of aneurysms, a special case of expansive remodeling. We propose that the redox modulation of vascular remodeling may reflect (1) remodeling pathophysiology is dominated by a particularly redox-sensitive cell type, e.g., endothelial cells (2) redox pathways are temporospatially coordinated at an organ level across distinct cellular and acellular structures or (3) the tensional homeostasis setpoint is closely connected to redox signaling. The mechanobiological/redox model discussed here can be a basis for improved understanding of remodeling and helps clarifying mechanisms underlying prevalent hard-to-treat diseases.

Full Text Available The OECD estimates that small and medium enterprises account for 90% of firms and employ 63% of the workforce in the world (Munro: 2013. Small and medium enterprises account for that amount of businesses thatit is senseless the arbitrariness with which they are defined. Language mainly used for definition is numbers, but it is difficult to find two institutions, statistical agencies or countries who speak the same language in terms of small and medium enterprises. Academics, authors, policy makers apply SMEdefinitions in terms of dichotomy between universality and standardization of a unique definition and relativity and sectored specialization. Although qualitative criteria-characteristics of SMEs easily distinguish them from large businesses, quantitative criteria are mainlyused for their dimensional classification. This paper deals with a critical approachto the definition of small and medium enterprises, inconsistencies in criteria and various proposed approaches to the definition towards universal acceptance.

Rib-eye steaks, from 3 forage-finished systems (S1, S2, and S3) and 1 commercial steak (C), either cooked by 1-sided-grilling or 2-sided-grilling, were evaluated for sensory acceptability [overall appearance (ORA) and overall appearance of fat (OAF) for raw steaks; overall appearance (OCA), overall beef aroma (OBA), overall beef flavor (OBF), juiciness, tenderness and overall liking (OL) for cooked steaks] and purchase intent by Hispanic, Asian and U.S. consumers. They also indicated preferred degree of doneness and cooking methods. Cross-cultural differences in preferences and consumer acceptability of rib-eye steaks were observed. Grilling was the most preferred cooking method. Hispanics and Asians preferred medium and/or medium well, while U.S. consumers preferred medium and/or medium rare. For cooked steaks, the population effect was significant for all sensory attributes; Asians generally scored lower than did Hispanics and U.S. consumers. C and S3 generally had higher scores for all sensory attributes across 3 populations. Purchase intent for all forage-finished steaks was higher for Hispanics and U.S. consumers compared to Asians (50.0% to 77.8% compared with 43.2% to 65.9%). Attributes influencing purchase intent of forage-finished steaks differed among populations: tenderness (odds ratio = 1.4) for Hispanics, OCA (odds ratio = 1.5) for Asians, and OBF (odds ratio = 1.3) for U.S. consumers. Overall, this study demonstrated that the type of forage-finished system and ethnic differences influenced sensory acceptability and purchase intent of forage-finished rib-eye steaks. Demand for forage-finished beef has increased worldwide due to its potential health benefits. Little is known regarding the cross-cultural effects on the consumer acceptance of forage-finished beef. We evaluated sensory acceptance and purchase intent of raw and cooked forage-finished rib-eye steaks using Hispanic, Asian, and U.S. (White and African American) populations. This study

To (1) determine diabetes patients' acceptance of Internet-based interventions (IBIs) for depression, to (2) examine the effectiveness of an acceptance facilitating intervention (AFI) and to (3) explore subgroup specific effects. 141 diabetes patients from two inpatient rehabilitation units and one outpatient clinic in Germany were randomly allocated to an intervention (IG) and a no-intervention control group (CG). The IG received an AFI consisting of a personal information session before filling-out a questionnaire on patients' acceptance of IBIs, predictors of acceptance (performance expectancy, effort expectancy, social influence, facilitating conditions, and Internet anxiety) as well as sociodemographic, depression-related and diabetes-related variables. The CG filled out the questionnaire immediately. Patients' acceptance of IBIs was measured with a four-item scale (sum-score ranging from 4 to 20). The CG showed a low (50.7%) to medium (40.8%) acceptance with only 8.5% of all diabetes patients reporting a high acceptance of IBIs for depression. The AFI had no significant effect on acceptance (IG: M=10.55, SD=4.69, n=70; KG: M=9.65, SD=4.27, n=71; d=0.20 [95%-CI: -0.13;0.53]) and the predictors of acceptance. Yet, subgroup analyses yielded a trend for depressed, diabetes-related distressed, female and younger (Internet to profit from the AFI. Diabetes patients show a rather low acceptance toward IBIs for depression. Findings indicate that the AFI is likely to be effective in the subgroup of depressed, diabetes-related distressed, female or younger diabetes patients, but not in the whole target population. Hence, AFIs might need to be tailored to the specific needs of subpopulations. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

Nayantara Padhi

2018-02-01

Full Text Available In the global movement towards open knowledge society, open educational resources (OER have become a prominent contributor as a medium of education, research and training. In India, the phenomenon of OER is still in nascent stage. Although the country has been massively investing on growth and usage of ICT, it still requires acceptance of OER as a medium of education, research or training. Particularly, adoption and usage of OER posses several challenges such as accessibility, reliability, copy right etc. There is plethora of research studies on the ICT usage in education in India, but there is hardly any empirical research evidence on OER in India. With this backdrop, at the first instance it is very much essential to investigate the acceptance and usability of OER in India. This paper focuses on faculty perception by applying Unified Theory of Acceptance and Use of Technology (UTAUT model. Apart from this, the study also identifies the challenges associated with OER. For the purpose of this survey data is collected from 22 Indian universities located pan India. The outcome of this empirical research shall certainly useful and provide guidelines for the policy makers and users of OER in India.

In the past decades, the major focus for nuclear power has been the design and construction of nuclear plants of ever increasing size. This was appropriate for many industrialized countries, which could readily add generation capability to their electrical grids in large increments. However, recently there has been an increasing emphasis on the development of small and medium reactors especially to meet needs in developing countries where electrical grids cannot accept the additional capacity of a large nuclear plant. The paper presents an estimation of the world market for small and medium sized reactors giving the basic assumptions, criteria, scope, methods and important factors. (author)

Full Text Available Abstract:Small and medium hotel companies in the majority of developed tourist countries have dominant role in hotel industry. The same situation is with Serbia. An important precondition for successful business of a hotel is accepting and applying basic pillars of marketing concept i.e. satisfying needs and expectations of guests inorder to achieve profit. Small hotel companies have specific problems in their daily business. Top priority in management and surviving of hotels is cash, because fixed costs are very dominant so hotels earmark more resources for them than for marketing. This means higher engagement and involvement of the state in furtherdevelopment of small and medium hotel companies in Serbia. The state should provide favourable subsidized credit lines for small and medium hotel companies in Serbia, through appropriate support programmes.

Full Text Available Introduction: Human functioning is based on physical, psychological, social and spiritual areas. The emergence of cancer and all types of problems affect these areas. Adapting to cancer is very important for the process of therapy, and acceptance of the disease is its determinant. Aim of the research study : To determine the relationship between oncological patients physical fitness and their acceptance of the disease. Material and methods: The following research techniques and tools have been used: a questionnaire survey, the Repta operation scale for assessing the functionality of patients in the course of the disease, a modified Pain Assessment Worksheet for evaluating the intensity of pain and its impact on daily activities and the AIS scale to assess the degree of acceptance of the disease. Results: Most of the respondents were fully efficient in the field of the activities of daily living. The vast majority of respondents did not feel pain, or felt pain that could be taken lightly. Pain that made daily functioning difficult, particularly in mobility and locomotion, concerned only persons over 60 years old. In the study group there was dominantly an average degree of acceptance of the disease; a small group was marked by a high level, and only a few people showed a lack of acceptance of the disease. Independent people and people in need of assistance accepted the illness at a medium level, and vulnerable patients showed the lowest level of acceptance. Conclusions : The efficiency of patients with cancer affects the level of acceptance of the disease. Cancer for the majority of respondents is not an obstacle in performing basic activities. Most respondents accept the disease, a small part selects a high level, and only a few people show a lack of acceptance of the disease.

Designing the ideal model for assessment of wound contamination after gunshot injuries: a comparative experimental study

2012-04-01

Full Text Available Abstract Background Modern high-velocity projectiles produce temporary cavities and can thus cause extensive tissue destruction along the bullet path. It is still unclear whether gelatin blocks, which are used as a well-accepted tissue simulant, allow the effects of projectiles to be adequately investigated and how these effects are influenced by caliber size. Method Barium titanate particles were distributed throughout a test chamber for an assessment of wound contamination. We fired .22-caliber Magnum bullets first into gelatin blocks and then into porcine hind limbs placed behind the chamber. Two other types of bullets (.222-caliber bullets and 6.5 × 57 mm cartridges were then shot into porcine hind limbs. Permanent and temporary wound cavities as well as the spatial distribution of barium titanate particles in relation to the bullet path were evaluated radiologically. Results A comparison of the gelatin blocks and hind limbs showed significant differences (p Conclusion Gelatin is only of limited value for evaluating the path of high-velocity projectiles and the contamination of wounds by exogenous particles. There is a direct relationship between the presence of gas cavities in the tissue along the bullet path and caliber size. These cavities, however, are only mildly contaminated by exogenous particles.

Common camera calibration methods employed in current laparoscopic augmented reality systems require the acquisition of multiple images of an entire checkerboard pattern from various poses. This lengthy procedure prevents performing laparoscope calibration in the operating room (OR). The purpose of this work was to develop a fast calibration method for electromagnetically (EM) tracked laparoscopes, such that the calibration can be performed in the OR on demand. We designed a mechanical tracking mount to uniquely and snugly position an EM sensor to an appropriate location on a conventional laparoscope. A tool named fCalib was developed to calibrate intrinsic camera parameters, distortion coefficients, and extrinsic parameters (transformation between the scope lens coordinate system and the EM sensor coordinate system) using a single image that shows an arbitrary portion of a special target pattern. For quick evaluation of calibration results in the OR, we integrated a tube phantom with fCalib prototype and overlaid a virtual representation of the tube on the live video scene. We compared spatial target registration error between the common OpenCV method and the fCalib method in a laboratory setting. In addition, we compared the calibration re-projection error between the EM tracking-based fCalib and the optical tracking-based fCalib in a clinical setting. Our results suggest that the proposed method is comparable to the OpenCV method. However, changing the environment, e.g., inserting or removing surgical tools, might affect re-projection accuracy for the EM tracking-based approach. Computational time of the fCalib method averaged 14.0 s (range 3.5 s-22.7 s). We developed and validated a prototype for fast calibration and evaluation of EM tracked conventional (forward viewing) laparoscopes. The calibration method achieved acceptable accuracy and was relatively fast and easy to be performed in the OR on demand.

An emerging trend in Asian higher education is English-medium instruction (EMI), which uses English as the primary instructional language. EMI prepares domestic students for international leadership; however, students report difficulty in learning, and educators have raised questions concerning the effectiveness of EMI. The flipped learning model (FLM), in which lecture and homework activities for a course are reversed, was applied to an English-medium course offered by a college of nursing in Korea. The aims of this study were to: 1) revise an existing English-medium nursing course using the FLM; 2) explore students' learning experiences and their acceptance of the FLM; and 3) identify key factors in the success of FLM. We used a descriptive, cross-sectional, mixed-methods design and the participants were students at one nursing school in Korea. A series of course development meetings with faculties from the nursing school and the center for teaching and learning were used to develop the course format and content. We conducted course evaluations using the Flipped Course Evaluation Questionnaire with open-ended questions and focus group interviews. Students (N=75) in a 15-week nursing course responded to a survey after completing the course. Among them, seven students participated in one of two focus groups. Overall, students accepted and favored the flipped learning strategy, and indicated that the method enhanced lecture content and their understanding of it. Factors associated with effective instruction included structured monitoring systems and motivational environments. The FLM requires sufficient preparation to facilitate student motivation and maximize learning outcomes.

Effective-Medium Models for Marine Gas Hydrates, Mallik Revisited

2011-12-01

Hertz-Mindlin type effective-medium dry-rock elastic models have been commonly used for more than three decades in rock physics analysis, and recently have been applied to assessment of marine gas hydrate resources. Comparisons of several effective-medium models with derivative well-log data from the Mackenzie River Valley, Northwest Territories, Canada (i.e. Mallik 2L-38 and 5L-38) were made several years ago as part of a marine gas hydrate joint industry project in the Gulf of Mexico. The matrix/grain supporting model (one of the five models compared) was clearly a better representation of the Mallik data than the other four models (2 cemented sand models; a pore-filling model; and an inclusion model). Even though the matrix/grain supporting model was clearly better, reservations were noted that the compressional velocity of the model was higher than the compressional velocity measured via the sonic logs, and that the shear velocities showed an even greater discrepancy. Over more than thirty years, variations of Hertz-Mindlin type effective medium models have evolved for unconsolidated sediments and here, we briefly review their development. In the past few years, the perfectly smooth grain version of the Hertz-Mindlin type effective-medium model has been favored over the infinitely rough grain version compared in the Gulf of Mexico study. We revisit the data from the Mallik wells to review assertions that effective-medium models with perfectly smooth grains are a better predictor than models with infinitely rough grains. We briefly review three Hertz-Mindlin type effective-medium models, and standardize nomenclature and notation. To calibrate the extended effective-medium model in gas hydrates, we use a well accepted framework for unconsolidated sediments through Hashin-Shtrikman bounds. We implement the previously discussed effective-medium models for saturated sediments with gas hydrates and compute theoretical curves of seismic velocities versus gas hydrate

Experience has shown that a critical part of the high-heat flux (HHF) plasma-facing component (PFC) is the armour to heat sink bond. An experimental study was performed in order to define acceptance criteria with regards to thermal hydraulics and fatigue performance of the International Thermonuclear Experimental Reactor (ITER) divertor PFCs. This study, which includes the manufacturing of samples with calibrated artificial defects relevant to the divertor design, is reported in this paper. In particular, it was concluded that defects detectable with non-destructive examination (NDE) techniques appeared to be acceptable during HHF experiments relevant to heat fluxes expected in the ITER divertor. On the basis of these results, a set of acceptance criteria was proposed and applied to the European vertical target medium-size qualification prototype: 98% of the inspected carbon fibre composite (CFC) monoblocks and 100% of tungsten (W) monoblock and flat tiles elements (i.e. 80% of the full units) were declared acceptable.

Bridging the Gap between Social Acceptance and Ethical Acceptability.

Science.gov (United States)

Taebi, Behnam

2017-10-01

New technology brings great benefits, but it can also create new and significant risks. When evaluating those risks in policymaking, there is a tendency to focus on social acceptance. By solely focusing on social acceptance, we could, however, overlook important ethical aspects of technological risk, particularly when we evaluate technologies with transnational and intergenerational risks. I argue that good governance of risky technology requires analyzing both social acceptance and ethical acceptability. Conceptually, these two notions are mostly complementary. Social acceptance studies are not capable of sufficiently capturing all the morally relevant features of risky technologies; ethical analyses do not typically include stakeholders' opinions, and they therefore lack the relevant empirical input for a thorough ethical evaluation. Only when carried out in conjunction are these two types of analysis relevant to national and international governance of risky technology. I discuss the Rawlsian wide reflective equilibrium as a method for marrying social acceptance and ethical acceptability. Although the rationale of my argument is broadly applicable, I will examine the case of multinational nuclear waste repositories in particular. This example will show how ethical issues may be overlooked if we focus only on social acceptance, and will provide a test case for demonstrating how the wide reflective equilibrium can help to bridge the proverbial acceptance-acceptability gap. © 2016 The Authors Risk Analysis published by Wiley Periodicals, Inc. on behalf of Society for Risk Analysis.

Full Text Available The International Financial Reporting Standard for Small and Medium-sized entities (IFRS for SMEs was published as a standard by the International Accounting Standards Board (IASB during July 2009. During 2007 South Africa became one of the first countries and the first country in Africa to early accept the proposed accounting standard (exposure draft of an IFRS for SMEs. The accounting standard will probably also be accepted by numerous other countries. The aim of this article is to investigate the applicability of this accounting standard. The results indicated that the IFRS for SMEs remains too comprehensive for the majority of small companies. The IFRS for SMEs does not satisfy the needs of South African users of small company financial statements, and as a result the accounting requirements should be simplified.

As a response to climate change and the desire to gain independence from imported fossil fuels, there is a pressure to increase the proportion of electricity from renewable sources which is one of the reasons why electricity grids are currently being turned into Smart Grids. In this paper, we focus...... on private consumers’ acceptance of having Smart Grid technology installed in their home. We analyse acceptance in a combined framework of the Technology Acceptance Model and the Norm Activation Model. We propose that individuals are only likely to accept Smart Grid technology if they assess usefulness...... in terms of a positive impact for society and the environment. Therefore, we expect that Smart Grid technology acceptance can be better explained when the well-known technology acceptance parameters included in the Technology Acceptance Model are supplemented by moral norms as suggested by the Norm...

Acceptance test for graphite components and construction status of HTTR

International Nuclear Information System (INIS)

Iyoku, T.; Ishihara, M.; Maruyama, S.; Shiozawa, S.; Tsuji, N.; Miki, T.

1996-01-01

In March, 1991, the Japan Atomic Energy Research Institute (JAERI) started to constructed the High Temperature engineering Test Reactor(HTTR) which is a 30-MW(thermal) helium gas-cooled reactor with a core composed of prismatic graphite blocks piled on the core support graphite structures. Two types of graphite materials are used in the HTTR. One is the garde IG-110, isotropic fine grain graphite, another is the grade PGX, medium-to-fine grained molded graphite. These materials were selected on the basis of the appropriate properties required by the HTTR reactor design. Industry-wide standards for an acceptance test of graphite materials used as main components of a nuclear reactor had not been established. The acceptance standard for graphite components of the HTTR, therefore, was drafted by JAERI and reviewed by specialists outside JAERI. The acceptance standard consists of the material testing, non-destructive examination such as the ultrasonic and eddy current testings, dimensional and visual inspections and assembly test. Ultrasonic and eddy current testings are applied to graphite logs to detect an internal flaw and to graphite components to detect a surface flaw, respectively. The assembly test is performed at the works, prior to their installation in the reactor pressure vessel, to examine fabricating precision of each component and alignment of piled-up structures. The graphite components of the HTTR had been tested on the basis of the acceptance standard. It was confirmed that the graphite manufacturing process was well controlled and high quality graphite components were provided to the HTTR. All graphite components except for the fuel graphite blocks are to be installed in the reactor pressure vessel of the HTTR in September 1995. The paper describes the construction status of the HTTR focusing on the graphite components. The acceptance test results are also presented in this paper. (author). Figs

'That proves my point': How mediums reconstrue disconfirmation in medium-sitter interactions.

Science.gov (United States)

Enoksen, Anette Einan; Dickerson, Paul

2018-04-01

Previous research has examined how the talk of mediums attends to the epistemological status of their readings. Such work has identified that mediums frequently use question-framed propositions that are typically confirmed by the sitter, thereby conferring epistemological status on the medium. This study seeks to investigate what happens when the sitter disconfirms the propositions of the medium. The study focuses on the ways in which such disconfirmation can be responded to such that it is reconstrued as evidence of the psychic nature of the medium's reading. Televised demonstrations of psychic readings involving British and US mediums and their sitters are analysed. The results suggest that mediums rework disconfirmation as proof in several ways: first, by emphasizing the different access that sitter and medium have to knowledge (e.g., about the future); second, as evidence that the medium has access to the actual voice of the deceased (and may therefore mishear what the deceased has said to them); and third, as revealing an important truth that has hitherto been concealed from the sitter. The implications of these findings are considered for cases where speakers bring different and potentially competing, epistemological resources to an interaction. © 2018 The British Psychological Society.

This paper discusses about the characteristics of supersonic projectile shock wave in muzzle region during firing of high explosive anti-tank (HEAT) and high explosive (HE) projectiles. HEAT projectiles are fired horizontally at a muzzle velocity of Mach 3.5 from a medium caliber tank gun equipped with a newly designed multi-perforated muzzle brake, whereas HE projectiles are fired at elevation angles at a muzzle velocity of Mach 2 from a large caliber howitzer equipped with a newly designed double-baffle muzzle brake. In the near field, pressure signatures of the N-wave generated from projectiles are measured by 32-microphone ring array wrapped by cotton sheath. Records measured by the microphone array are used to demonstrate several key characteristics of the shock wave of supersonic projectile. All measurements made in this study can be a significant reference for developing guns, tanks, or the chassis of fighting vehicles.

As part of an ongoing development of third-generation advanced high-strength steels with acceptable cost, austenite reversion treatment of medium Mn steels becomes attractive because it can give rise to a microstructure of fine mixture of ferrite and austenite, leading to both high strength and large elongation. The growth of austenite during intercritical annealing is crucial for the final properties, primarily because it determines the fraction, composition, and phase stability of austenite. In the present work, the growth of austenite from as-quenched lath martensite in medium Mn steels has been simulated using the DICTRA software package. Cementite is added into the simulations based on experimental observations. Two types of systems (cells) are used, representing, respectively, (1) austenite and cementite forming apart from each other, and (2) austenite forming on the cementite/martensite interface. An interfacial dissipation energy has also been added to take into account a finite interface mobility. The simulations using the first type of setup with an addition of interfacial dissipation energy are able to reproduce the observed austenite growth in medium Mn steels reasonably well.

Technical problems in case of utilizing uranium of medium enrichment for a research reactor

Usually, highly enriched uranium of 90 - 93% is used for research reactors, but the US government proposed the strong policy to use low enriched uranium of the uranium of medium enrichment in unavoidable case from the viewpoint of the resistance to nuclear proliferation in November, 1977. This policy is naturally applied to Japan also. The export of highly enriched uranium will be permitted only when the President approves it after the technical and economical evaluations by the government. The Kyoto University high flux reactor has the features which are not seen in other research reactors, such as medical irradiation, and it is hard to attain the objectives of researches unless HEU is used. The application for the export of HEU was accepted in February, 1978. The nuclear characteristics of the KUHFR when medium or low enriched uranium is used, the criticality experiment in the KUCA using the uranium of medium enrichment, and the burning test on the uranium fuel plates of medium enrichment are described. The research project to lower the degree of enrichment in the fuel for research and test reactors is expected to be continued down to less than 20%. The MEU of 45% enrichment will be actually used in 1983. (Kako, I.)

In nuclear power generation, the development of large reactors has been promoted as the main energy source in Japan. However, world economy entered low growth age, and the growth of electric power demand slowed down. Accordingly, attention has been paid to the medium and small reactors that can cope with whatever needs by serializing their types in addition to the nuclear power plants of medium output matching to electric power demand. In order to cope with these new needs, the economical efficiency of medium and small reactors must be as close as possible to that of large reactors, and as the countermeasures to the demerits due to small size, those must be made into the plants having simplified systems and the safety easily acceptable to public. Hitachi Ltd. plans to develop the natural circulation type medium and small BWRs of 600 NWe output class, HSBWR-600, on the basis of the nuclear power plant technology based on the rich results of design and operation of BWRs obtained so far, and to rank them as one of the BWR series. The target of their development design, the circumstance of their development, the core design and the thermo-hydraulic characteristics, the reactor pressure vessel and in-core structures, the safety design, system design, building layout and the evaluation are reported.

The acceptance of uncertainty - a move towards an 'ecological' concept of law

International Nuclear Information System (INIS)

Ladeur, K.H.

1986-01-01

Within the framework of a study investigating the law applied as an instrument of global social steering, the author analyses the acceptance of uncertainty and resulting impacts, taking nuclear energy and the problems involved as the example to illustrate his point. The relationship between the law and social knowledge is first explained against the historical background and then in the light of the regulatory system established for the peaceful use of nuclear energy in accordance with the current scientific knowledge. The author tries to show why the reference to science as a medium of ''certainty and unambigiousness'' did not create the acceptance of nuclear energy one had hoped for. The evolution of the structure of social knowledge, i.e. increasing, awareness of uncertainty, enforces new ways and standards of reflection and enhanced need for consensus, because uncertainty is a problem of evaluating of risks, and cannot be solved by scientific or technical information.

There will be growing demands for energy in the coming decades. One aspect of particular importance is that prospects for nuclear energy will to a considerable extent be influenced by developing countries. Since population growth will occur primarily in developing countries nuclear energy cannot play a significant global role without being a viable option in these countries. Since new power plants to be built will have to be compatible with regional electricity grids, this may result in a greater focus on plants in the small and medium range, defined by the International Atomic Energy Agency (IAEA) to produce up to 700 Megawatt of electrical power. This paper first examines the driving forces that could influence the development of nuclear energy in general and of Small and Medium Sized Reactors (SMRs) in particular in the next decades and identifies key factors in that process. Concerns over climate change may to a certain extent influence the discussion on future energy options. Other factors of equal importance for the future of nuclear are a continued emphasis on maintaining high safety standards, the implementation of acceptable solutions for spent fuel and radioactive waste disposal and a globally accepted non-proliferation regime, factors that may in turn have an impact on public acceptance. Economic competitiveness of nuclear energy is an additional important factor, and without being commercially viable, no energy source can in the long run represent a major and stable component in a competitive energy sector. The introduction of SMRs in developing countries poses additional challenges, such as investment limitations. Technology development plays an important role in keeping the nuclear option open for countries wishing to use nuclear reactors to meet their energy needs, and advances in reactor design will be important to enable a significant nuclear component in developing countries. This paper considers the contribution that nuclear science and

Full Text Available Background: Six Sigma is related to product’s characteristics and parameters of actions, needed to obtain these products. On the other hand, it is a multi-step, cyclic process aimed at the improvements leading to global standard, closed to the perfection. There is a growing interest in Six Sigma methodology among smaller organizations but there are still too little publications presented such events in the sector of small and medium enterprises, especially based on good empirical results. It was already noticed at the phase of the preliminary researches, that only small part of companies from this sector in Pomerian region use elements of this methodology. Methods: The companies were divided into groups by the type of their activities as well as the employment size. The questionnaires were sent to 150 randomly selected organizations in two steps and were addressed to senior managers. The questionnaire contained the questions about basic information about a company, the level of the knowledge and the practical application of Six Sigma methodology, opinions about improvements of processes occurring in the company, opinions about trainings in Six Sigma methodology. Results: The following hypotheses were proposed, statistically verified and received the answer: The lack of the adequate knowledge of Six Sigma methodology in SMEs limits the possibility to effectively monitor and improve processes - accepted. The use of statistical tools of Six Sigma methodology requires the broad action to popularize this knowledge among national SMEs - accepted. The level of the awareness of the importance as well as practical use of Six Sigma methodology in manufacturing SMEs is higher than in SMEs providing services - rejected, the level is equal. The level of the knowledge and the use of Six Sigma methodology in medium manufacturing companies is significantly higher than in small manufacturing companies - accepted.

The current study systematically reviews and summarizes the existing literature of game acceptance, identifies the core determinants, and evaluates the strength of the relationships in the extended technology acceptance model. Moreover, this study segments video games into two categories: hedonic and utilitarian and examines player acceptance of these two types separately. Through a meta-analysis of 50 articles, we find that perceived ease of use (PEOU), perceived usefulness (PU), and perceived enjoyment (PE) significantly associate with attitude and behavioral intention. PE is the dominant predictor of hedonic game acceptance, while PEOU and PU are the main determinants of utilitarian game acceptance. Furthermore, we find that respondent type and game platform are significant moderators. Findings of this study provide critical insights into the phenomenon of game acceptance and suggest directions for future research.

Fast, Larissa A; Freeman, C Faith; O'Neill, Michael; Rowley, Elizabeth

2013-04-01

This paper documents current understanding of acceptance as a security management approach and explores issues and challenges non-governmental organisations (NGOs) confront when implementing an acceptance approach to security management. It argues that the failure of organisations to systematise and clearly articulate acceptance as a distinct security management approach and a lack of organisational policies and procedures concerning acceptance hinder its efficacy as a security management approach. The paper identifies key and cross-cutting components of acceptance that are critical to its effective implementation in order to advance a comprehensive and systematic concept of acceptance. The key components of acceptance illustrate how organisational and staff functions affect positively or negatively an organisation's acceptance, and include: an organisation's principles and mission, communications, negotiation, programming, relationships and networks, stakeholder and context analysis, staffing, and image. The paper contends that acceptance is linked not only to good programming, but also to overall organisational management and structures. © 2013 The Author(s).

2017-06-01

Chronic pain places a burden on individuals and the economy. Although there is evidence for the effectiveness of cognitive-behavior therapy, it is recognized that the effects are limited. Acceptance and Commitment Therapy (ACT), which aims to increase valued action in the presence of pain, has been suggested as an alternative approach. The objective of this review was to determine the clinical effectiveness of ACT for chronic pain in adults when compared with control conditions and other active treatments. The searches of this systematic review were conducted in the Cochrane library, MEDLINE, EMBASE, CINAHL Plus (EBSCO), and PsycINFO. Grey literature, reference list, and reverse citation searches were also completed. Eleven trials were included. ACT was favored over controls (no alternative intervention or treatment as usual). Significant, medium to large effect sizes were found for measures of pain acceptance and psychological flexibility, which are typically considered processes of ACT. Significant small to medium effect sizes were found for measures of functioning, anxiety, and depression. Measures of pain intensity and quality of life were not significantly different than zero. Generally effect sizes were smaller at follow-up. ACT was more clinically effective than controls on a number of outcomes. It is possible that methodological limitations, some of which are common to psychological trials, may have led to overestimated effects. Only a few studies compared ACT to active treatments and while the evidence is promising for ACT in the treatment of chronic pain, further methodologically robust trials are required.

A Fourier analysis on the maximum acceptable grid size for discrete proton beam dose calculation

Li, Haisen S.; Romeijn, H. Edwin; Dempsey, James F.

2006-01-01

We developed an analytical method for determining the maximum acceptable grid size for discrete dose calculation in proton therapy treatment plan optimization, so that the accuracy of the optimized dose distribution is guaranteed in the phase of dose sampling and the superfluous computational work is avoided. The accuracy of dose sampling was judged by the criterion that the continuous dose distribution could be reconstructed from the discrete dose within a 2% error limit. To keep the error caused by the discrete dose sampling under a 2% limit, the dose grid size cannot exceed a maximum acceptable value. The method was based on Fourier analysis and the Shannon-Nyquist sampling theorem as an extension of our previous analysis for photon beam intensity modulated radiation therapy [J. F. Dempsey, H. E. Romeijn, J. G. Li, D. A. Low, and J. R. Palta, Med. Phys. 32, 380-388 (2005)]. The proton beam model used for the analysis was a near mono-energetic (of width about 1% the incident energy) and monodirectional infinitesimal (nonintegrated) pencil beam in water medium. By monodirection, we mean that the proton particles are in the same direction before entering the water medium and the various scattering prior to entrance to water is not taken into account. In intensity modulated proton therapy, the elementary intensity modulation entity for proton therapy is either an infinitesimal or finite sized beamlet. Since a finite sized beamlet is the superposition of infinitesimal pencil beams, the result of the maximum acceptable grid size obtained with infinitesimal pencil beam also applies to finite sized beamlet. The analytic Bragg curve function proposed by Bortfeld [T. Bortfeld, Med. Phys. 24, 2024-2033 (1997)] was employed. The lateral profile was approximated by a depth dependent Gaussian distribution. The model included the spreads of the Bragg peak and the lateral profiles due to multiple Coulomb scattering. The dependence of the maximum acceptable dose grid size on the

The light vector mesons ($\\rho$, $\\omega$, and $\\phi$) were produced in deuterium, carbon, titanium, and iron targets in a search for possible in-medium modifications to the properties of the $\\rho$ meson at normal nuclear densities and zero temperature. The vector mesons were detected with the CEBAF Large Acceptance Spectrometer (CLAS) via their decays to $e^{+}e^{-}$. The rare leptonic decay was chosen to reduce final-state interactions. A combinatorial background was subtracted from the invariant mass spectra using a well-established event-mixing technique. The $\\rho$ meson mass spectrum was extracted after the $\\omega$ and $\\phi$ signals were removed in a nearly model-independent way. Comparisons were made between the $\\rho$ mass spectra from the heavy targets ($A > 2$) with the mass spectrum extracted from the deuterium target. With respect to the $\\rho$-meson mass, we obtain a small shift compatible with zero. Also, we measure widths consistent with standard nuclear many-body eff

To examine the associations of body fatness, metabolic and inflammatory markers with retinal vessel calibers among children. We performed a population-based cohort study among 4145 school-age children. At the median age of 6.0 years (95% range 5.8, 8.0 years), we measured body mass index, total and abdominal fat mass, metabolic and inflammatory markers (blood levels of lipids, insulin and C-peptide and C-reactive protein) and retinal vascular calibers from retinal photographs. We observed that compared with normal weight children, obese children had narrower retinal arteriolar caliber (difference -0.21 s.d. score (SDS; 95% confidence interval (CI) -0.35, -0.06)), but not venular caliber. Continuous analyses showed that higher body mass index and total body fat mass, but not android/gynoid fat mass ratio and pre-peritoneal fat mass, were associated with narrower retinal arteriolar caliber (Pfat mass), but not with retinal venular caliber. Lipid and insulin levels were not associated with retinal vessel calibers. Higher C-reactive protein was associated with only wider retinal venular caliber (difference 0.10 SDS (95% CI 0.06, 0.14) per SDS increase in C-reactive protein). This latter association was not influenced by body mass index. Higher body fatness is associated with narrower retinal arteriolar caliber, whereas increased C-reactive protein levels are associated with wider retinal venular caliber. Increased fat mass and inflammation correlate with microvascular development from school-age onwards.

Vu, Kim-Phuong L.; Strybel, Thomas; Chiappe, Dan; Morales, Greg; Battiste, Vernol; Shively, Robert Jay

2014-01-01

Previously, we showed that air traffic controllers (ATCos) rated UAS pilot verbal response latencies as acceptable when a 1.5 s delay was added to the UAS pilot responses, but a 5 s delay was rated as mostly unacceptable. In the present study we determined whether a 1.5 s added delay in the UAS pilots' verbal communications would affect ATCos interactions with UAS and other conventional aircraft when the number and speed of the UAS were manipulated. Eight radar-certified ATCos participated in this simulation. The ATCos managed a medium altitude sector containing arrival aircraft, en route aircraft, and one to four UAS. The UAS were conducting a surveillance mission and flew at either a "slow" or "fast" speed. We measured both UAS and conventional pilots' verbal communication latencies, and obtained ATCos' acceptability ratings for these latencies. Although the UAS pilot response latencies were longer than those of conventional pilots, the ATCos rated UAS pilot verbal communication latencies to be as acceptable as those of conventional pilots. Because the overall traffic load within the sector was held constant, ATCos only performed slightly worse when multiple UAS were in their sector compared to when only one UAS was in the sector. Implications of these findings for UAS integration in the NAS are discussed.

Wherefore a study of consumer attitudes towards mobile advertising can be considered necessary in order to create a lucrative business. Even though this to...

Tracer transfer in consolidated porous medium and fractured porous medium: experimentations and modelling

International Nuclear Information System (INIS)

Dalla Costa, C.

2007-07-01

We try to identify and model physical and chemical mechanisms governing the water flow and the solute transport in fractured consolidated porous medium. An original experimental device was built. The 'cube' consists of an idealized fractured medium reproduced by piling up consolidated porous cubes of 5 cm edge. Meanwhile, columns of the homogeneous consolidated porous medium are studied. The same anionic tracing technique is used in both cases. Using a system analysis approach, we inject concentration pulses in the device to obtain breakthrough curves. After identifying the mass balance and the residence time, we fit the CD and the MIM models to the experimental data. The MIM model is able to reproduce experimental curves of the homogeneous consolidated porous medium better than the CD model. The mobile water fraction is in accordance with the porous medium geometry. The study of the flow rate influence highlights an interference dispersion regime. It was not possible to highlight the observation length influence in this case. On the contrary, we highlight the effect of the observation scale on the fractured and porous medium, comparing the results obtained on a small 'cube' and a big 'cube'. The CD model is not satisfactory in this case. Even if the MIM model can fit the experimental breakthrough curves, it was not possible to obtain unique parameters for the set of experiments.

The use of medium enriched uranium fuel for research reactors

International Nuclear Information System (INIS)

1979-01-01

The evaluation described in the present paper concerns the use of medium enriched uranium fuel for our research reactors. The underlying assumptions set up for the evaluation are as follows: (1) At first, the use of alternative fuel should not affect, even to a small extent, research and development programs in nuclear energy utilization, which were described in the previous paper. Hence the use of lower enrichment fuel should not cause any reduction in reactor performances. (2) The fuel cycle cost for operating research reactors with alternative fuel, excepting R and D cost for such fuel, should not increase beyond an acceptable limit. (3) The use of alternative fuel should be satisfactory with respect to non-proliferation purposes, to the almost same degree as the use of 20% enriched uranium fuel

Small and medium power reactors: the past, present and future

International Nuclear Information System (INIS)

Smith, T.G.G.

1987-01-01

The history of small and medium power reactors (SMPRs) is reviewed. Although the power range goes up to plants with an electricity output of 600MWe, the focus is on plants of 250-300 MWe. The role of the International Atomic Energy Agency in promoting their use for electrical energy production for developing countries is examined. It can be shown that there is a considerable potential market for SMPRs which will increase later this century and into the next. There are, however, a number of problems to be overcome. These are not in the technical aspects but problems of costs and financing. Thus efforts should be made to reduce capital costs, shorten construction time and find potential customers who are acceptable borrowers to the international banking world. Various types of reactor are examined. (U.K.)

Study of preservation dynamics of ureaplasma laboratory strain live cultures and their DNA in transport medium at varying temperature. The study was carried out in laboratory strains Ureaplasma urealyticum serotype 8 and Ureaplasma parvum serotype 1. The quantity of live ureaplasmas was determined by method of tenfold dilutions in liquid medium. The growth of ureaplasmas was registered by changes in the color of the cultivation medium due to its alkalization by metabolism products and expressed in CCU/ml. DNA quantity in samples was determined by real time PCR performed by using Florocenosis-micoplasmas-FL test system produced by ILS. Live ureaplasmas wer shown to be preserved in transport medium at 4 degrees C for 12 - 29 days, at 18 - 22 degrees C--for 9 - 20 days and at 37 degrees C--for only 2 days. In samples incubated at 37 degrees C the quantity of live ureaplasmas increased and then sharply decreased to 0, at lower temperature titers of the cells decreased smoothly. The quantity of ureaplasma DNA in the process of their incubation did not change significantly. Fundamental differences in the duration of survival of U. urealyticum strain and U. parvum strain in transport medium at varying temperature were not detected. Based on the studies performed a practical conclusion can be drawn that in cases of emergency when clinical material transportation is necessary its storage in transport medium for several days is acceptable.

FUZZY ACCEPTANCE SAMPLING AND CHARACTERISTIC CURVES

Directory of Open Access Journals (Sweden)

Ebru Turano?lu

2012-02-01

Full Text Available Acceptance sampling is primarily used for the inspection of incoming or outgoing lots. Acceptance sampling refers to the application of specific sampling plans to a designated lot or sequence of lots. The parameters of acceptance sampling plans are sample sizes and acceptance numbers. In some cases, it may not be possible to define acceptance sampling parameters as crisp values. These parameters can be expressed by linguistic variables. The fuzzy set theory can be successfully used to cope with the vagueness in these linguistic expressions for acceptance sampling. In this paper, the main distributions of acceptance sampling plans are handled with fuzzy parameters and their acceptance probability functions are derived. Then the characteristic curves of acceptance sampling are examined under fuzziness. Illustrative examples are given.

Quantitative microwave impedance microscopy with effective medium approximations

Directory of Open Access Journals (Sweden)

T. S. Jones

2017-02-01

Full Text Available Microwave impedance microscopy (MIM is a scanning probe technique to measure local changes in tip-sample admittance. The imaginary part of the reported change is calibrated with finite element simulations and physical measurements of a standard capacitive sample, and thereafter the output ΔY is given a reference value in siemens. Simulations also provide a means of extracting sample conductivity and permittivity from admittance, a procedure verified by comparing the estimated permittivity of polytetrafluoroethlyene (PTFE to the accepted value. Simulations published by others have investigated the tip-sample system for permittivity at a given conductivity, or conversely conductivity and a given permittivity; here we supply the full behavior for multiple values of both parameters. Finally, the well-known effective medium approximation of Bruggeman is considered as a means of estimating the volume fractions of the constituents in inhomogeneous two-phase systems. Specifically, we consider the estimation of porosity in carbide-derived carbon, a nanostructured material known for its use in energy storage devices.

The Interstellar Medium

Lequeux, James

2005-01-01

Describing interstellar matter in our galaxy in all of its various forms, this book also considers the physical and chemical processes that are occurring within this matter. The first seven chapters present the various components making up the interstellar matter and detail the ways that we are able to study them. The following seven chapters are devoted to the physical, chemical and dynamical processes that control the behaviour of interstellar matter. These include the instabilities and cloud collapse processes that lead to the formation of stars. The last chapter summarizes the transformations that can occur between the different phases of the interstellar medium. Emphasizing methods over results, "The Interstellar Medium" is written for graduate students, for young astronomers, and also for any researchers who have developed an interest in the interstellar medium.

To provide an ideal solution for a specific problem of gastric cancer detection in which low-scattering regions simultaneously existed with both the non- and high-scattering regions, a novel hybrid radiosity-SP3 equation based reconstruction algorithm for bioluminescence tomography was proposed in this paper. In the algorithm, the third-order simplified spherical harmonics approximation (SP3) was combined with the radiosity equation to describe the bioluminescent light propagation in tissues, which provided acceptable accuracy for the turbid medium with both low- and non-scattering regions. The performance of the algorithm was evaluated with digital mouse based simulations and a gastric cancer-bearing mouse based in situ experiment. Primary results demonstrated the feasibility and superiority of the proposed algorithm for the turbid medium with low- and non-scattering regions.

Wire-guided biliary cannulation has been demonstrated to improve cannulation rates and reduce post-ERCP pancreatitis (PEP), but the impact of wire caliber has not been studied. This study compares successful cannulation rates and ERCP adverse events by using a 0.025-inch and 0.035-inch guidewire. A randomized, single blinded, prospective, multicenter trial at 9 high-volume tertiary-care referral centers in the Asia-Pacific region was performed. Patients with an intact papilla and conventional anatomy who did not have malignancy in the head of the pancreas or ampulla and were undergoing ERCP were recruited. ERCP was performed by using a standardized cannulation algorithm, and patients were randomized to either a 0.025-inch or 0.035-inch guidewire. The primary outcomes of the study were successful wire-guided cannulation and the incidence of PEP. Overall successful cannulation and ERCP adverse events also were studied. A total of 710 patients were enrolled in the study. The primary wire-guided biliary cannulation rate was similar in 0.025-inch and 0.035-inch wire groups (80.7% vs 80.3%; P = .90). The rate of PEP between the 0.025-inch and the 0.035-inch wire groups did not differ significantly (7.8% vs 9.3%; P = .51). No differences were noted in secondary outcomes. Similar rates of successful cannulation and PEP were demonstrated in the use of 0.025-inch and 0.035-inch guidewires. (Clinical trial registration number: NCT01408264.). Copyright © 2018.

Tonni, I; Oliver, R G

2013-08-01

The purpose of the study was to highlight students' and mentors' acceptability of a reflective e-portfolio instituted in a postgraduate orthodontic programme in the UK. A reflective e-portfolio was developed on the basis of principles provided by a literature search and was piloted for 2 months with six students and seven mentors. At the end of the experience, mentors' and students' acceptability of the e-portfolio with a reflective component was studied using questionnaires. The data were analysed using basic quantitative and qualitative methods. Students' response highlighted acceptability issues related to each aspect of the e-portfolio derived from the literature: relevance of the e-portfolio reflective part; time required for the process; support and mentoring; the implementation method; and the electronic medium. Mentors showed a more positive attitude towards the e-portfolio, expressing only some concerns about the time involved in using it. Furthermore, the analysis of the data highlighted some other acceptability matters: the specificity of the e-portfolio, the communication amongst students and the relationship between students and mentors. The future successful implementation of the reflective e-portfolio will depend on the productive management of the acceptability issues identified by students and mentors, in particular:(i)the specificity of the e-portfolio that would avoid its overlapping with other part of the programme;(ii)the increasing communication amongst students to improve their knowledge of the reflective writing process; and (iii)the development of a relationship between students and mentors helping to create the appropriate environment for reflection. © 2013 John Wiley & Sons A/S.

The purpose of this study was to evaluate the feasibility of a dry bowel preparation, i.e. without laxative fluids, for virtual CT colonography (VCTC), and its impact on patient acceptance compared with conventional colonoscopy (CC). A randomly chosen patient population scheduled for CC (n=11) was first submitted to VCTC after a dry preparation, consisting of low-residue meals combined with a small amount of a iodinated water-soluble contrast medium during each meal 3 days before VCTC. In different colon segments and between different persons, the degree of tagging in VCTC was evaluated and graded. Patient acceptance and future preference were assessed for both preparations as well as for both investigations. The mixing of the contrast with the intestinal content results in contrast impregnated stool, the tagged feces. The degree of fecal tagging was good in the majority of the patients and the colonic segments, especially in the descending colon and sigmoid. Furthermore, patient acceptance and preference were clearly in favour of VCTC compared with CC merely because of the non-invasiveness of the dry preparation. Dry bowel preparation and VCTC is a promising approach towards a patient-friendly colon cancer-screening setup. (orig.)

The influence of family-related factors on the succession process in small and medium-sized family businesses

Directory of Open Access Journals (Sweden)

E Venter

2014-07-01

Full Text Available In this study family-related factors that can influence the succession process in small and medium-sized family businesses are empirically investigated.  The dependent variable in this study is measured by two underlying dimensions, namely satisfaction with the process and continued profitability of the business.  The empirical results indicate that the family-related factors that influence both the aforementioned dimensions are the mutual acceptance of roles, the relationship between the owner-manager and successor, and family harmony.  The continued profitability of the business is also influenced by the agreement to continue the business. The existence of family harmony in itself influences the relationship between the owner-manager and successor, the agreement to continue the business, as well as the mutual acceptance of roles.  The managerial implications of these empirical findings are discussed and recommendations offered.

One-stoma carinoplasty: right upper sleeve lobectomy with hemicarinectomy for resection of right-tracheobronchial-angle tumors.

Kaya, Seyda Ors; Sevinc, Serpil; Ceylan, Kenan Can; Usluer, Ozan; Unsal, Saban

2013-01-01

Tracheobronchial-angle tumors involve the right main bronchus, the right upper lobar bronchus, and the lateral wall of the lower trachea. Resecting these tumors is one of the most complex procedures in thoracic surgery. In cases of high-caliber mismatch, the selection of a suitable anastomotic technique can be challenging. We found that our use of a one-stoma carinoplasty technique overcame high-caliber mismatch after the resection of these tumors. From 2009 through 2012, 8 men (mean age, 59 ± 6.2 yr; range, 46-66 yr) underwent complete resection of non-small-cell right-tracheobronchial-angle tumors at our institution. In every case, right upper sleeve lobectomy, wedge carinal resection, and one-stoma carinoplasty were applied. After tumor resection, one patient with hemoptysis and bronchopleural fistula underwent a completion pneumonectomy and died 10 days postoperatively. Bronchoscopy was necessary in 2 patients who had atelectasis in the contralateral lung. At a mean follow-up duration of 19.43 ± 8.4 months (range, 0.2-27.1 mo), 6 patients were alive and free of disease. We conclude that our one-stoma carinoplasty technique enables the resection of tumors at the right tracheobronchial angle, with acceptable morbidity and mortality rates. This method saves the unaffected part of the ipsilateral lung and can overcome high-caliber mismatch. Because of these and other advantages, we suggest that using our method first might preclude having to perform a right carinal sleeve pneumonectomy or using Barclay's method.

Tattoo: a multifaceted medium of communication

Directory of Open Access Journals (Sweden)

Christian Wymann

2010-11-01

Full Text Available This article suggests the systems theoretical distinction of form/medium as a useful tool for distinguishing social phenomena that might look as if they stem from the same process. This is shown to be the case for the tattoo and tattooing. The tattoo is conceived as a medium of communication through which different forms of communication emerge. Tattooing is one of these forms of communication that shapes the medium in a particular way. The current article sheds a special light on its intricate, communicational constellation, for which the concept of parallax is suggested. Law, medicine and cosmetics as other forms of communication use the medium of tattoo in their own way as well. The form/medium distinction allows us to grasp these different forms of communication, while it shows that they share the tattoo as medium. The article’s ultimate goal is to illustrate that the tattoo figures as a multifaceted medium of communication.

Effective medium theory for anisotropic metamaterials

KAUST Repository

Zhang, Xiujuan

2015-01-20

Materials with anisotropic material parameters can be utilized to fabricate many fascinating devices, such as hyperlenses, metasolids, and one-way waveguides. In this study, we analyze the effects of geometric anisotropy on a two-dimensional metamaterial composed of a rectangular array of elliptic cylinders and derive an effective medium theory for such a metamaterial. We find that it is possible to obtain a closed-form analytical solution for the anisotropic effective medium parameters, provided the aspect ratio of the lattice and the eccentricity of the elliptic cylinder satisfy certain conditions. The derived effective medium theory not only recovers the well-known Maxwell-Garnett results in the quasi-static regime, but is also valid beyond the long-wavelength limit, where the wavelength in the host medium is comparable to the size of the lattice so that previous anisotropic effective medium theories fail. Such an advance greatly broadens the applicable realm of the effective medium theory and introduces many possibilities in the design of structures with desired anisotropic material characteristics. A real sample of a recently theoretically proposed anisotropic medium, with a near-zero index to control the flux, is achieved using the derived effective medium theory, and control of the electromagnetic waves in the sample is clearly demonstrated.

Acceptance promotion is supposed to be an indispensable premise for a successful realization of an energy concept. The contribution identifies deficiencies of the energy policy, including intransparency, complexity of decision procedures, for instance in case of the so called energy transmission line extension acceleration law, that has caused irritation and anger in the public. The justification of acceptance promotion is questioned in connection with the German nuclear policy reversal following the Fukushima accident. A research program ''public acceptance of large-scale power plants for electricity generation'' is presented. The issues criteria and limits of acceptability are of main importance for this discussion.

In a prospective randomised study three groups of 30 patients each were subjected to CT of the entire abdomen. The oral intestinal contrast media used were iodine solution (2%), barium suspension (1.5%) and paraffin emulsion (25%). The results were evaluated according to imaging, artifacts, assessability of the intestinal wall, taste and side effects. All three contrast media are suitable for marking the gastrointestinal tract; paraffin shows advantages in the upper part of the tract and is the only medium that enables assessment of the wall, while causing the lowest rate of artifacts. Barium has a high acceptance and the best tolerance of all contrast agents. (orig.) [de

RFS or Regles Fondamentales de Surete (Basic Safety Rules) applicable to certain types of nuclear facilities lay down requirements with which compliance, for the type of facilities and within the scope of application covered by the RFS, is considered to be equivalent to compliance with technical French regulatory practice. The object of the RFS is to take advantage of standardization in the field of safety, while allowing for technical progress in that field. They are designed to enable the operating utility and contractors to know the rules pertaining to various subjects which are considered to be acceptable by the Service Central de Surete des Installations Nucleaires, or the SCSIN (Central Department for the Safety of Nuclear Facilities). These RFS should make safety analysis easier and lead to better understanding between experts and individuals concerned with the problems of nuclear safety. The SCSIN reserves the right to modify, when considered necessary, any RFS and specify, if need be, the terms under which a modification is deemed retroactive. The role of this RFS is to define the safety objectives and the basic design philosophy for surface centres for long-term storage of packages of radioactive waste with short or medium half-life and with low or medium specific activity

On risks and acceptability

International Nuclear Information System (INIS)

Watson, S.R.

1981-01-01

A very attractive notion is that it should be possible not only to determine how much risk is associated with any particular activity, but also to determine if that risk is acceptable. Stated boldly this seems an entirely unobjectionable and indeed a very acceptable notion. There is, however, underlying this idea, a mistaken view of risk which we might refer to as the ''phlogiston'' theory of risk. In this paper, presented at the SRP meeting on Ethical and Legal Aspects of Radiological Protection, the phlogiston theory of risk is described; secondly, it will be argued that it is too simple a theory to be realistic or useful; and thirdly, the management of risk will be placed in a wider decision framework. Acceptability, it will be argued is highly dependent on context, and it is not possible, therefore, to lay down generally applicable notions of acceptability. (author)

Intralesional treatment for cutaneous leishmaniasis has been applied for over 30 years at the Oswaldo Cruz Foundation, Rio de Janeiro, with good therapeutic results and without relevant systemic toxicity. Meglumine antimoniate was injected subcutaneously, using a long medium-caliber needle (for example, 30mm × 0.8mm); patients received 1-3 injections, with 15-day intervals. The technique is described in detail sufficient to enable replication. The treatment of cutaneous leishmaniasis with intralesional meglumine antimoniate is a simple, effective, and safe technique, which may be used in basic healthcare settings.

Full Text Available The Student from Prague  (1913 is considered to be the first  film d’art produced in Germany. The film is based on a script by Ha nns Heinz Ewers, writer and ardent advocate of this new medium. With roots in German romantic ism, particularly in regard to motifs in the works by E.T.A. Hoffmann and Adelbert von Chamisso, The Student from Prague explored the optical possibilities offered by the doppelganger character. This literary framework supports the plot, gives credibility to the movie and contribut es to the acceptance of films as an art medium. It also marks the rise of German cinema on an international level, which reached its peak in the 1920s with the movement known as ‘German expressionism’.

The proposed STAM extended previous technology acceptance models and theories by adding age-related health and ability characteristics of older people. The proposed STAM was empirically tested using a cross-sectional questionnaire survey with a sample of 1012 seniors aged 55 and over in Hong Kong. The result showed that STAM was strongly supported and could explain 68% of the variance in the use of gerontechnology. For older Hong Kong Chinese, individual attributes, which include age, gender, education, gerontechnology self-efficacy and anxiety, and health and ability characteristics, as well as facilitating conditions explicitly and directly affected technology acceptance. These were better predictors of gerontechnology usage behaviour (UB) than the conventionally used attitudinal factors (usefulness and ease of use).

Public acceptance of small reactors

International Nuclear Information System (INIS)

McDougall, D.S.

1997-01-01

The success of any nuclear program requires acceptance by the local public and all levels of government involved in the decision to initiate a reactor program. Public acceptance of a nuclear energy source is a major challenge in successful initiation of a small reactor program. In AECL's experience, public acceptance will not be obtained until the public is convinced that the specific nuclear program is needed, safe and economic and environmental benefit to the community. The title of public acceptance is misleading. The objective of the program is a fully informed public. The program proponent cannot force public acceptance, which is beyond his control. He can, however, ensure that the public is informed. Once information has begun to flow to the public by various means as will be explained later, the proponent is responsible to ensure that the information that is provided by him and by others is accurate. Most importantly, and perhaps most difficult to accomplish, the proponent must develop a consultative process that allows the proponent and the public to agree on actions that are acceptable to the proponent and the community

Background. The ATDC5 cell line is regarded as an excellent cell model for chondrogenesis. In most studies with ATDC5 cells, insulin medium (IM) was used to induce chondrogenesis while chondrogenic medium (CM), which was usually applied in chondrogenesis of mesenchymal stem cells (MSCs), was rarely used for ATDC5 cells. This study was mainly designed to investigate the effect of IM, CM, and growth medium (GM) on chondrogenesis of ATDC5 cells. Methods. ATDC5 cells were, respectively, cultured ...

Full Text Available Current technological advances, particularly in information and communications technology (ICT and social media have sparked a phenomenon in the business world. The existence of social commerce (s-commerce, which is a combination of e-commerce and social media, has opened up greater opportunities for SMEs in Malaysia. The use of s-commerce as a medium for marketing and buying and selling is capable of helping SMEs to increase the sales and profitability of their businesses. However, according to studies conducted by SME Corp Malaysia, the usage of e-commerce and social media is still low. Attitude and self-efficacy are variables that are often used in studies related to entrepreneurs and their intention to accept a new business innovation or technology. Therefore, this study was undertaken to identify the internal factors within entrepreneurs, namely attitude and self-efficacy, which influence the acceptance and use of s-commerce among SMEs in Malaysia.

We discuss various aspects of pion physics in the nuclear medium. We first study s-wave pion-nucleus interaction in connection with chiral symmetry restoration and quark condensate in the nuclear medium. We then address the question of p-wave pion-nucleus interaction and collective pionic modes in nuclei and draw the consequences for in medium ππ correlations especially in the scalar-isoscalar channel. We finally discuss the modification of the rho meson mass spectrum at finite density and/or temperature in connection with relativistic heavy ion collisions

Prebiotic water/ice as medium for peptide catlysis and RNA world

DEFF Research Database (Denmark)

Wieczorek, Rafal

The emergence of RNA chains from prebiotic soup is considered a stumbling block in the RNA world theory (Orgel 2004). Both the activation of RNA monomers and their subsequent oligomerization is hard to achieve in accepted early Earth conditions, thus putting doubt on the prebiotic plausibility....... As an environment medium we have used water/ice eutectic phase – conditions believed to be present on the early Earth and many icy moons. In this work we describe a prebiotically plausible system in which L-dipeptides containing a histidine residue, primarily the SerHis dipeptide act as catalyst for the formation...... able to succesfully demonstratate formation of short oligomers of RNA. During the oligomerization, an active intermediate (dipeptide-mononucleotide) is produced, which is the reactive species. Details of the mechanism and kinetics, which could be elucidated with a set of control experiments, further...

Collaborative Manufacturing for Small-Medium Enterprises

Irianto, D.

2016-02-01

Manufacturing systems involve decisions concerning production processes, capacity, planning, and control. In a MTO manufacturing systems, strategic decisions concerning fulfilment of customer requirement, manufacturing cost, and due date of delivery are the most important. In order to accelerate the decision making process, research on decision making structure when receiving order and sequencing activities under limited capacity is required. An effective decision making process is typically required by small-medium components and tools maker as supporting industries to large industries. On one side, metal small-medium enterprises are expected to produce parts, components or tools (i.e. jigs, fixture, mold, and dies) with high precision, low cost, and exact delivery time. On the other side, a metal small- medium enterprise may have weak bargaining position due to aspects such as low production capacity, limited budget for material procurement, and limited high precision machine and equipment. Instead of receiving order exclusively, a small-medium enterprise can collaborate with other small-medium enterprise in order to fulfill requirements high quality, low manufacturing cost, and just in time delivery. Small-medium enterprises can share their best capabilities to form effective supporting industries. Independent body such as community service at university can take a role as a collaboration manager. The Laboratory of Production Systems at Bandung Institute of Technology has implemented shared manufacturing systems for small-medium enterprise collaboration.

Properties of the nuclear medium

International Nuclear Information System (INIS)

Baldo, M; Burgio, G F

2012-01-01

We review our knowledge on the properties of the nuclear medium that have been studied, over many years, on the basis of many-body theory, laboratory experiments and astrophysical observations. Throughout the presentation particular emphasis is placed on the possible relationship and links between the nuclear medium and the structure of nuclei, including the limitations of such an approach. First we consider the realm of phenomenological laboratory data and astrophysical observations and the hints they can give on the characteristics that the nuclear medium should possess. The analysis is based on phenomenological models, that however have a strong basis on physical intuition and an impressive success. More microscopic models are also considered, and it is shown that they are able to give invaluable information on the nuclear medium, in particular on its equation of state. The interplay between laboratory experiments and astrophysical observations is particularly stressed, and it is shown how their complementarity enormously enriches our insights into the structure of the nuclear medium. We then introduce the nucleon–nucleon interaction and the microscopic many-body theory of nuclear matter, with a critical discussion about the different approaches and their results. The Landau–Fermi liquid theory is introduced and briefly discussed, and it is shown how fruitful it can be in discussing the macroscopic and low-energy properties of the nuclear medium. As an illustrative example, we discuss neutron matter at very low density, and it is shown how it can be treated within the many-body theory. The general bulk properties of the nuclear medium are reviewed to indicate at which stage of our knowledge we stand, taking into account the most recent developments both in theory and experiments. A section is dedicated to the pairing problem. The connection with nuclear structure is then discussed, on the basis of the energy density functional method. The possibility of

Probabilistic relationships in acceptable risk studies

Benjamin, J.R.

1977-01-01

Acceptable risk studies involve uncertainties in future events; consequences and associated values, the acceptability levels, and the future decision environment. Probabilistic procedures afford the basic analytical tool to study the influence of each of these parameters on the acceptable risk decision, including their interrelationships, and combinations. A series of examples are presented in the paper in increasing complexity to illustrate the principles involved and to quantify the relationships to the acceptable risk decision. The basic objective of such studies is to broaden the scientific basis of acceptable risk decision making. It is shown that rationality and consistency in decision making is facilitated by such studies and that rather simple relationships exist in many situations of interest. The variation in criteria associated with an increase in the state of knowledge or change in the level of acceptability is also discussed. (Auth.)

The characteristic adventurous spirit that built American technology will eventually lead to American acceptance of nuclear power unless an overpowering loss of nerve causes us to reject both nuclear technology and world leadership. The acceptance of new technology by society has always been accompanied by activist opposition to industralization. To resolve the debate between environmental and exploitive extremists, we must accept with humility the basic premise that human accomplishment is a finite part of nature

Approaches to acceptable risk

International Nuclear Information System (INIS)

Whipple, C.

1997-01-01

Several alternative approaches to address the question open-quotes How safe is safe enough?close quotes are reviewed and an attempt is made to apply the reasoning behind these approaches to the issue of acceptability of radiation exposures received in space. The approaches to the issue of the acceptability of technological risk described here are primarily analytical, and are drawn from examples in the management of environmental health risks. These include risk-based approaches, in which specific quantitative risk targets determine the acceptability of an activity, and cost-benefit and decision analysis, which generally focus on the estimation and evaluation of risks, benefits and costs, in a framework that balances these factors against each other. These analytical methods tend by their quantitative nature to emphasize the magnitude of risks, costs and alternatives, and to downplay other factors, especially those that are not easily expressed in quantitative terms, that affect acceptance or rejection of risk. Such other factors include the issues of risk perceptions and how and by whom risk decisions are made

Acceptance and Commitment Therapy (ACT) has growing support for chronic pain. However, more accessible treatment delivery is needed. This study evaluated the feasibility of online ACT for patients with complex chronic pain in the United Kingdom to determine whether a larger trial is justified. Participants with chronic pain and clinically meaningful disability and distress were randomly assigned to ACT online plus specialty medical pain management, or specialty medical management alone. Participants completed questionnaires at baseline, and 3- and 9-month post-randomization. Primary feasibility outcomes included recruitment, retention and treatment completion rates. Secondary outcomes were between-groups effects on treatment outcomes and psychological flexibility. Of 139 potential participants, 63 were eligible and randomized (45% recruitment rate). Retention rates were 76-78% for follow-up assessments. Sixty-one per cent of ACT online participants completed treatment. ACT online was less often completed by employed (44%) compared to unemployed (80%) participants. Fifty-six per cent of ACT online participants rated themselves as 'much improved' or better on a global impression of change rating, compared to only 20 per cent of control participants. Three-month effects favouring ACT online were small for functioning, medication and healthcare use, committed action and decentring, medium for mood, and large for acceptance. Small-to-medium effects were maintained for functioning, healthcare use and committed action at 9 months. Online ACT for patients with chronic pain in the United Kingdom appears feasible to study in a larger efficacy trial. Some adjustments to treatment and trial procedures are warranted, particularly to enhance engagement among employed participants. This study supports the feasibility of online Acceptance and Commitment Therapy for chronic pain in the United Kingdom and a larger efficacy trial. Refinements to treatment delivery, particularly to

De Nardo, Thales; Gabel, Rodney M; Tetnowski, John A; Swartz, Eric R

2016-01-01

This study explored the relationship between self-acceptance of stuttering and (1) psychosocial factors (self-esteem, hostility towards others, emotional support, and perceived discrimination); (2) treatment history (support group participation, therapy duration, and perceived therapy success); and (3) previously reported variables in self-acceptance of stuttering, which include age and stuttering severity. Participants were 80 adults who stutter who were recruited with assistance from the National Stuttering Association and Board Certified Specialists in Fluency Disorders. Participants completed an electronic survey composed of an acceptance of stuttering scale, psychosocial scales, and a participant information questionnaire. Statistical analysis identified significant correlations between participants' reports of self-acceptance of stuttering and self-esteem, perceived discrimination, hostility towards others, and perceived therapy outcome. Self-esteem was positively correlated with self-acceptance, while hostility towards others and perceived discrimination was negatively correlated with self-acceptance. Participants who perceived their therapy outcome to be successful were significantly more likely to report higher levels of self-acceptance. No significant relationships were found between self-acceptance of stuttering and support group participation, emotional support, stuttering severity, and participant age. This exploratory investigation has provided a foundation for future studies on the self-acceptance of stuttering. The findings indicate common psychosocial variables in self-acceptance of stuttering and of other disabilities. The significant relationships between self-acceptance of stuttering and psychosocial and therapeutic variables found need to be further explored to identify its causalities and clinical implications. The reader will be able to (1) discuss the importance of assessing self-acceptance of stuttering, (2) summarize the literature on self-acceptance

Differentiated influences of risk perceptions on nuclear power acceptance according to acceptance targets: Evidence from Korea

The determinants of the public's nuclear power acceptance have received considerable attention as decisive factors regarding nuclear power policy. However, the contingency of the relative importance of different determinants has been less explored. Building on the literature of psychological distance between the individual and the object, the present study demonstrates that the relative effects of different types of perceived risks regarding nuclear power generation differ across acceptance targets. Using a sample of Korea, our results show that, regarding national acceptance of nuclear power generation, perceived risk from nuclear power plants exerts a stronger negative effect than that from radioactive waste management; however, the latter exerts a stronger negative effect than the former on local acceptance of a nuclear power plant. This finding provides implications for efficient public communication strategy to raise nuclear power acceptance

Full Text Available Purpose: The purpose of this study is to evaluate the effect of transfer of donor corneal tissue from McCarey–Kaufmann (MK medium to Optisol-GS on corneal endothelium. Methods: This was a prospective, randomized comparative study. Twenty paired human donor corneal tissues of optical quality were retrieved. One tissue of the pair was preserved in Optisol-GS preservative medium (Group A and other tissue of the pair in MK medium (Group B at the time of corneoscleral disc excision. Within 12 h of retrieval, each cornea was evaluated using slit-lamp biomicroscopic examination and specular microscopic analysis. Group B corneas were transferred to Optisol-GS medium within 48–53 h of retrieval. Specular analysis of the paired corneas was repeated 3 h after transferring to Optisol-GS. On day 7 of storage, specular analysis of both the tissues was repeated. Results: The average age of the donor at the time of death was 29 years (16–68 years. The reduction in endothelial cell count, from baseline, in Groups A and B was 5.5% and 5.8% (P = 0.938 on the 3rd day and 8.2% and 12.6% (P = 0.025 on the 7th day, respectively, postretrieval. The coefficient of variation (CV increased by 36% (P = 0.021 and hexagonality reduced by 19% (P = 0.007 on day 7. All tissues retained an endothelial cell density higher than the accepted critical level for penetrating keratoplasty. Conclusion: Significant endothelial cell loss was noted while transferring tissues from one medium to another, necessitating the need for reevaluation of transferred tissues before utilization.

Shen Jianqi

2006-01-01

A new scheme to realize simultaneously negative permittivity and permeability in a coherent atomic vapor medium (photonic-resonant material) via a coherent driving mechanism is suggested. It is verified that the atomic system coherently driven by a strong optical field will give rise to a negative refractive index in certain probe frequency ranges. One of the most remarkable features of the present scheme is such that a slab fabricated by the left-handed vapor medium is an ideal candidate for designing perfect lenses since the photonic-resonant atomic vapor cannot only exhibit an isotropic negative refractive index, but also provide a good impedance match at the air-medium interfaces

2016-05-01

This work studies the in vitro degradation of Mg alloys for bioabsorbable implant applications under near physiological conditions. For this purpose, the degradation behaviour of Mg alloys in Dulbecco's modified eagle medium (DMEM) which is a commonly used cell culture medium is analysed. Unfortunately, DMEM can be contaminated by microorganisms, acidifying the medium and accelerating the Mg degradation process by dissolution of protective degradation layers, such as (Mgx,Cay)(PO4)z. In this paper the influence of sterilization by applying UV-C radiation and antibiotics (penicillin/streptomycin) is analysed with two implant material candidates: Mg-Gd and Mg-Ag alloys; and pure magnesium as well as Mg-4Y-3RE as a reference.

Indications for in-medium modifications of hadron properties are reported from photoabsorption and meson production experiments. Strong medium modifications are observed in inclusive photoabsorption experiments and theoretical models investigate the in-medium dynamics of baryon resonances and their coupling to mesons. Recent experiments study the in-medium behavior of scalar and vector mesons where theoretical models expect in-medium modifications of the meson spectral functions that might be connected to partial restoration of chiral symmetry

Computed tomography of the cervical spine with iv injection of contrast medium

Magnaldi, S.; Pozzi-Mucelli, R.S.; Cova, M.A.; De Morpurgo, P.

1989-01-01

Computed Tomography (CT) without contrast medium is largely applied to the study of intervertebral disk pathology in the lumbar spine, but has not been widely accepted in cervical spine, due to technical and anatomical limitations. For these reasons many neuroradiologists still prefer myelography or myelo-CT. CT may yield better results if combined with iv contrast medium injection, which allows a better visualization of disk herniation. This technique is aimed at enhancing the density of the venous plexus which is located close to the intervertebral disk the vertebral bodies and the neural foramina. A better contrast enhancement is thus obtained between the disk and the spinal cord. The authors' experience is based on 61 patients who underwent contrast enhanced CT; in 22 cases myelography and myelo-CT were also performed. The authors describe their technique and the most frequent CT findings of disk hernation: the typical finding includes a focal hypodensity surrounded by a linear blush, due to a posteriorly dislocated epidural vein. The posterior linear blush alone may be present in few cases. Contrast enhanced CT is very useful in the study of disk pathology of the cervical spine, even when compared with myelography and myelo-CT, due the increase in the density of epidural plexus it allows. However, the technique must be very accurate if the same results as those of myelo-CT are to be obtained

Replacement of meat by meat substitutes. A survey on person- and product-related factors in consumer acceptance.

Hoek, Annet C; Luning, Pieternel A; Weijzen, Pascalle; Engels, Wim; Kok, Frans J; de Graaf, Cees

2011-06-01

What does it take to increase the consumption of meat substitutes and attract new consumers? We identified main barriers and drivers by a consumer survey (n=553) in the U.K. and the Netherlands. Person-related factors (food neophobia and food choice motives) and product-related attitudes and beliefs towards meat and meat substitutes were compared between non-users (n=324), light/medium-users (n=133) and heavy-users of meat substitutes (n=96). Consumer acceptance was largely determined by the attitudes and beliefs towards meat substitutes and food neophobia. Key barriers for non-users and light/medium-users were the unfamiliarity with meat substitutes and the lower sensory attractiveness compared to meat. In addition, non-users had a higher tendency to avoid new foods. Hence, the less consumers were using meat substitutes, the more they wanted these products to be similar to meat. Although non-users and light/medium-users did recognize the ethical and weight-control aspects of meat substitutes, this was obviously less relevant to them. Actually, only heavy-users had high motivations to choose ethical foods, which explains their choice for meat substitutes. In order to make meat substitutes more attractive to meat consumers, we would not recommend to focus on communication of ethical arguments, but to significantly improve the sensory quality and resemblance to meat.

Stovas, A.; Alkhalifah, Tariq Ali

2012-01-01

To compute moveout in a transversely isotropic medium with tilted symmetry axis is a very complicated problem. We propose to split this problem into two parts. First, to compute the moveout in a corresponding VTI medium. Second, to map the computed moveout to a TTI medium.

Fractional diffusion equation for heterogeneous medium

Polo L, M. A.; Espinosa M, E. G.; Espinosa P, G.; Del Valle G, E.

2011-11-01

The asymptotic diffusion approximation for the Boltzmann (transport) equation was developed in 1950 decade in order to describe the diffusion of a particle in an isotropic medium, considers that the particles have a diffusion infinite velocity. In this work is developed a new approximation where is considered that the particles have a finite velocity, with this model is possible to describe the behavior in an anomalous medium. According with these ideas the model was obtained from the Fick law, where is considered that the temporal term of the current vector is not negligible. As a result the diffusion equation of fractional order which describes the dispersion of particles in a highly heterogeneous or disturbed medium is obtained, i.e., in a general medium. (Author)

Consumer acceptance of functional foods

DEFF Research Database (Denmark)

Frewer, Lynn J.; Scholderer, Joachim; Lambert, Nigel

2003-01-01

In the past, it has been assumed that consumers would accept novel foods if there is a concrete and tangible consumer benefit associated with them, which implies that those functional foods would quickly be accepted. However, there is evidence that individuals are likely to differ in the extent...... to which they are likely to buy products with particular functional properties. Various cross-cultural and demographic differences in acceptance found in the literature are reviewed, as well as barriers to dietary change. In conclusion, it is argued that understanding consumer's risk perceptions...

Kinetics of intravenous radiographic contrast medium injections as used on CT: simulation with time delay differential equations in a basic human cardiovascular multicompartment model.

Science.gov (United States)

Violon, D

2012-12-01

To develop a multicompartment model of only essential human body components that predicts the contrast medium concentration vs time curve in a chosen compartment after an intravenous injection. Also to show that the model can be used to time adequately contrast-enhanced CT series. A system of linked time delay instead of ordinary differential equations described the model and was solved with a Matlab program (Matlab v. 6.5; The Mathworks, Inc., Natick, MA). All the injection and physiological parameters were modified to cope with normal or pathological situations. In vivo time-concentration curves from the literature were recalculated to validate the model. The recalculated contrast medium time-concentration curves and parameters are given. The results of the statistical analysis of the study findings are expressed as the median prediction error and the median absolute prediction error values for both the time delay and ordinary differential equation systems; these are situated well below the generally accepted maximum 20% limit. The presented program correctly predicts the time-concentration curve of an intravenous contrast medium injection and, consequently, allows an individually tailored approach of CT examinations with optimised use of the injected contrast medium volume, as long as time delay instead of ordinary differential equations are used. The presented program offers good preliminary knowledge of the time-contrast medium concentration curve after any intravenous injection, allowing adequate timing of a CT examination, required by the short scan time of present-day scanners. The injected volume of contrast medium can be tailored to the individual patient with no more contrast medium than is strictly needed.

Optical illusions induced by rotating medium

Zang, XiaoFei; Huang, PengCheng; Zhu, YiMing

2018-03-01

Different from the traditional single-function electromagnetic wave rotators (rotate the electromagnetic wavefronts), we propose that rotating medium can be extended to optical illusions such as breaking the diffraction limit and overlapping illusion. Furthermore, the homogeneous but anisotropic rotating medium is simplified by homogeneous and isotropic positive-index materials according to the effective medium theory, which is helpful for future device fabrication. Finite element simulations for the two-dimensional case are performed to demonstrate these properties.

Sustainability and acceptance - new challenges for nuclear energy

International Nuclear Information System (INIS)

Lensa, W. von

2001-01-01

This paper discusses the concept of sustainability in relation to acceptance of nuclear energy. Acceptance is viewed in terms of public acceptance, industrial acceptance, and internal acceptance/consensus within the nuclear community. It addresses sustainability criteria, the need for innovation, and the different levels of acceptability. The mechanisms of risk perception are discussed along with the technological consequences from risk perception mechanisms leading to specific objections against nuclear energy. (author)

Nuclear Energy and Public Acceptance

International Nuclear Information System (INIS)

Daifuku, K.

2002-01-01

The continued use of nuclear power in the European Union and elsewhere requires an adequate level of public and political acceptance. A lack of acceptance is often mistakenly cited as a reason for the slowdown in nuclear power plant construction in Western Europe and as a justification for abandoning nuclear power. In fact, the reasons for the slowdown have more to do with the following two factors: Plentiful supplies of low-priced natural gas, making gas-fired power plants a more attractive investment choice; more than adequate supplies of electricity which have curbed the need for the construction of new plant of any kind. In general, moves towards a withdrawal from nuclear in certain Community countries have been due to party political pressures and have not been a response to public opposition to nuclear. In addition, opinion polls do not show widespread public opposition to the use of nuclear power. Figures consistently indicate that the use of nuclear power does not come high on the list of most people's main worries. Their main concerns focus on other issues such as crime and financial problems. In the main, electricity is taken for granted in the industrialised world. Electric power only becomes an issue when there is a threat of shortages. So if public acceptance is not the main obstacle, what is? Political acceptance is an integral part of the process in which nuclear becomes acceptable or not. The relationship between public and political acceptance and the role of the industry in this context, on how to foster a better trialogue, will be examined. (author)

Detection of phasic dopamine by D1 and D2 striatal medium spiny neurons.

Science.gov (United States)

Yapo, Cedric; Nair, Anu G; Clement, Lorna; Castro, Liliana R; Hellgren Kotaleski, Jeanette; Vincent, Pierre

2017-12-15

Brief dopamine events are critical actors of reward-mediated learning in the striatum; the intracellular cAMP-protein kinase A (PKA) response of striatal medium spiny neurons to such events was studied dynamically using a combination of biosensor imaging in mouse brain slices and in silico simulations. Both D1 and D2 medium spiny neurons can sense brief dopamine transients in the sub-micromolar range. While dopamine transients profoundly change cAMP levels in both types of medium spiny neurons, the PKA-dependent phosphorylation level remains unaffected in D2 neurons. At the level of PKA-dependent phosphorylation, D2 unresponsiveness depends on protein phosphatase-1 (PP1) inhibition by DARPP-32. Simulations suggest that D2 medium spiny neurons could detect transient dips in dopamine level. The phasic release of dopamine in the striatum determines various aspects of reward and action selection, but the dynamics of the dopamine effect on intracellular signalling remains poorly understood. We used genetically encoded FRET biosensors in striatal brain slices to quantify the effect of transient dopamine on cAMP or PKA-dependent phosphorylation levels, and computational modelling to further explore the dynamics of this signalling pathway. Medium-sized spiny neurons (MSNs), which express either D 1 or D 2 dopamine receptors, responded to dopamine by an increase or a decrease in cAMP, respectively. Transient dopamine showed similar sub-micromolar efficacies on cAMP in both D1 and D2 MSNs, thus challenging the commonly accepted notion that dopamine efficacy is much higher on D 2 than on D 1 receptors. However, in D2 MSNs, the large decrease in cAMP level triggered by transient dopamine did not translate to a decrease in PKA-dependent phosphorylation level, owing to the efficient inhibition of protein phosphatase 1 by DARPP-32. Simulations further suggested that D2 MSNs can also operate in a 'tone-sensing' mode, allowing them to detect transient dips in basal dopamine

Acceptability of GM foods among Pakistani consumers

2016-01-01

ABSTRACT In Pakistan majority of the consumers do not have information about genetically modified (GM) foods. In developing countries particularly in Pakistan few studies have focused on consumers' acceptability about GM foods. Using comprehensive primary dataset collected from 320 consumers in 2013 from Pakistan, this study analyzes the determinants of consumers' acceptability of GM foods. The data was analyzed by employing the bivariate probit model and censored least absolute deviation (CLAD) models. The empirical results indicated that urban consumers are more aware of GM foods compared to rural consumers. The acceptance of GM foods was more among females' consumers as compared to male consumers. In addition, the older consumers were more willing to accept GM food compared to young consumers. The acceptability of GM foods was also higher among wealthier households. Low price is the key factor leading to the acceptability of GM foods. The acceptability of the GM foods also reduces the risks among Pakistani consumers. PMID:27494790

Results from clinical trials indicate that Internet-based psychological pain interventions are effective in treating chronic pain. However, little is known about patients' acceptance of these programs and how to positively influence patients' intention to engage in them. Therefore, the present study aimed (1) to assess patients' acceptance of Internet-based interventions, and (2) to examine whether patients' acceptance can be increased by an acceptance facilitating intervention. A total of 104 patients with chronic pain from 2 pain units were randomly allocated to an intervention group (IG) and a no-intervention control group (CG). The IG was shown a short informational video about Internet-based psychological pain interventions before receiving a questionnaire on patients' acceptance of Internet-based psychological pain interventions and predictors of acceptance (performance expectancy, effort expectancy, social influence, facilitating conditions, Internet usage, and Internet anxiety). The CG filled out the questionnaire immediately. Patients' acceptance was measured with a 4-item scale (sum score ranging from 4 to 20). Baseline acceptance of Internet-based interventions was reported as low (sum-score:4-9) by 53.8%, moderate (10 to 15) by 42.3%, and high (16 to 20) by 3.9% of the patients with chronic pain in the CG. The IG showed a significantly higher acceptance (M = 12.17, SD = 4.22) than the CG (M = 8.94, SD = 3.71) with a standardized mean difference of d = 0.81 (95% CI, 0.41, 1.21). All predictor variables were significantly improved in the IG compared with the CG, except for Internet usage. Patients with chronic pain display a relatively low acceptance of Internet-based psychological pain interventions, which can be substantially increased by a short informational video.

Probing the mechanisms of drug release from amorphous solid dispersions in medium-soluble and medium-insoluble carriers.

Sun, Dajun D; Lee, Ping I

The objective of the current study is to mechanistically differentiate the dissolution and supersaturation behaviors of amorphous drugs from amorphous solid dispersions (ASDs) based on medium-soluble versus medium-insoluble carriers under nonsink dissolution conditions through a direct head-to-head comparison. ASDs of indomethacin (IND) were prepared in several polymers which exhibit different solubility behaviors in acidic (pH1.2) and basic (pH7.4) dissolution media. The selected polymers range from water-soluble (e.g., PVP and Soluplus) and water-insoluble (e.g., ethylcellulose and Eudragit RL PO) to those only soluble in an acidic or basic dissolution medium (e.g., Eudragit E100, Eudragit L100, and HPMCAS). At 20wt.% drug loading, DSC and powder XRD analysis confirmed that the majority of incorporated IND was present in an amorphous state. Our nonsink dissolution results confirm that whether the carrier matrix is medium soluble determines the release mechanism of amorphous drugs from ASD systems which has a direct impact on the rate of supersaturation generation, thus in turn affecting the evolution of supersaturation in amorphous systems. For example, under nonsink dissolution conditions, the release of amorphous IND from medium-soluble carriers is governed by a dissolution-controlled mechanism leading to an initial surge of supersaturation followed by a sharp decline in drug concentration due to rapid nucleation and crystallization. In contrast, the dissolution of IND ASD from medium-insoluble carriers is more gradual as drug release is regulated by a diffusion-controlled mechanism by which drug supersaturation is built up gradually and sustained over an extended period of time without any apparent decline. Since several tested carrier polymers can be switched from soluble to insoluble by simply changing the pH of the dissolution medium, the results obtained here provide unequivocal evidence of the proposed transition of kinetic solubility profiles from the

The purpose of this research is to explore enterprises' acceptance of Audience Response System (ARS) using Technology Acceptance Model (TAM). The findings show that (1) IT characteristics and facilitating conditions could be external variables of TAM. (2) The degree of E-business has positive significant correlation with behavioral intention of employees. (3) TAM is a good model to predict and explain IT acceptance. (4) Demographic variables, industry and firm characteristics have no significant correlation with ARS acceptance. The results provide useful information to managers and ARS providers that (1) ARS providers should focus more on creating different usages to enhance interactivity and employees' using intention. (2) Managers should pay attention to build sound internal facilitating conditions for introducing IT. (3) According to the degree of E-business, managers should set up strategic stages of introducing IT. (4) Providers should increase product promotion and also leverage academic and government to promote ARS.

Acceptability, acceptance and decision making

International Nuclear Information System (INIS)

Ackerschott, H.

2002-01-01

There is a fundamental difference between the acceptability of a civilizatory or societal risk and the acceptability of the decision-making process that leads to a civilizatory or societal risk. The analysis of individual risk decisions - regarding who, executes when which indisputably hazardous, unhealthy or dangerous behaviour under which circumstances - is not helpful in finding solutions for the political decisions at hand in Germany concerning nuclear energy in particular or energy in general. The debt for implementation of any technology, in the sense of making the technology a success in terms of broad acceptance and general utilisation, lies with the particular industry involved. Regardless of the technology, innovation research identifies the implementation phase as most critical to the success of any innovation. In this sense, nuclear technology is at best still an innovation, because the implementation has not yet been completed. Fear and opposition to innovation are ubiquitous. Even the economy - which is often described as 'rational' - is full of this resistance. Innovation has an impact on the pivotal point between stability, the presupposition for the successful execution of decisions already taken and instability, which includes insecurity, but is also necessary for the success of further development. By definition, innovations are beyond our sphere of experience; not at the level of reliability and trust yet to come. Yet they are evaluated via the simplifying heuristics for making decisions proven not only to be necessary and useful, but also accurate in the familiar. The 'settlement of the debt of implementation', the accompanying communication, the decision-making procedures concerning the regulation of averse effects of the technology, but also the tailoring of the new technology or service itself must be directed to appropriate target groups. But the group often aimed at in the nuclear debate, the group, which largely determines political

OTM Machine Acceptance: In the Arab Culture

Rashed, Abdullah; Santos, Henrique

Basically, neglecting the human factor is one of the main reasons for system failures or for technology rejection, even when important technologies are considered. Biometrics mostly have the characteristics needed for effortless acceptance, such as easiness and usefulness, that are essential pillars of acceptance models such as TAM (technology acceptance model). However, it should be investigated. Many studies have been carried out to research the issues of technology acceptance in different cultures, especially the western culture. Arabic culture lacks these types of studies with few publications in this field. This paper introduces a new biometric interface for ATM machines. This interface depends on a promising biometrics which is odour. To discover the acceptance of this biometrics, we distributed a questionnaire via a web site and called for participation in the Arab Area and found that most respondents would accept to use odour.

Prediction of Students’ Use and Acceptance of Clickers by Learning Approaches: A Cross-Sectional Observational Study

Directory of Open Access Journals (Sweden)

Kelvin Wan

2017-12-01

Full Text Available The student response system (a.k.a clickers had been widely used in classrooms for various pedagogical purposes these years. However, few of the studies examine students learning approaches toward both technology and engagement. The present study adopted a cross-sectional study method to investigate the relationship between students’ user acceptance of clickers, learning approaches, and general engagement in the clicker classes. A group of 3371 university students were investigated by an online questionnaire that contained with Unified Theory of Use and Acceptance of Technology, Study Process Questionnaire, and National Survey of Student Engagement across a two-semester span in 2015 and 2016. A regression analysis had been adopted to examine the relationship between those variables. Results indicated that a deep learning approach significantly predicted all user acceptance domains towards using clickers and significantly predicted several engagement domains such as collaborative learning and reflective and integrative learning. We concluded that deep learners tend to share a constructive attitude toward using clickers, especially when their peers are also using the clickers. While deep learners prefer integration of knowledge and skills from various sources and experiences, we hypothesize that their willingness to integrate clicker activities in their learning process stems from seeing clickers as a medium for consolidation in the learning process. Future research is, therefore, necessary to provide more detailed evidence of the characteristic of deep learners on the qualitative arm or in a way of mixed research method.

Improved lipid and biomass productivities in Chlorella vulgaris by differing the inoculation medium from the production medium

Directory of Open Access Journals (Sweden)

Shahrbanoo Hamedi

2016-06-01

Full Text Available Improvement of biomass and lipid productivities is now one of the main concerns in commercialization of microalgae cultivation as a feedstock for algal biofuel production. Conventional photoautotrophic processes using well-studied and rich in oil strain of Chlorella vulgaris are not able to meet such demands. A new strategy of inoculating algae production medium with cells grown in a different medium from the production medium was proposed herein. More specifically, when SH4 was used as production medium and N8 was used as inoculation medium, biomass and lipid productivities increased by 2.33 folds and 1.44 fold, respectively, compared with when the production and inoculation media were the same, such as SH4. The findings of the present investigation showed that this cultivation scheme resulted in 52% increase in cell number and 54% increase in dry weight leading to improved productivities. Although by even considering this improvement, photoautotrophic cultivation of algae can hardly compete with the heterotrophic cultivation, the high cost of hydrocarbon supply required in large-scale heterotrophic processes marks the technique proposed in the present study as a promising approach for commercialization of algal biofuel production.

Jokar, Nargesh Khatun; Noorhosseini, Seyyed Ali; Allahyari, Mohammad Sadegh; Damalas, Christos A

2017-07-31

The shift in consumers' preferences from synthetic to 'natural' products has led to a resurgence of interest in medicinal plants, particularly in developing countries. However, research data about consumers' preferences for particular products is hard to find. The main objective of this study was to contribute to the general understanding of consumers' intention for selecting medicinal herbs for consumption. Factors underpinning consumers' acceptance of medicinal herbs were studied with the technology acceptance model (TAM) in Rasht City of Iran using a structured questionnaire. Most respondents had low to moderate familiarity with consumption of medicinal herbs. However, about half of the respondents (47.5%) showed a high level of acceptance of medicinal herbs. Herbs like spearmint (Mentha spicata L.), spinach (Spinacia oleracea L.), basil (Ocimum basilicum L.), Damask rose (Rosa × damascena Herrm.), saffron (Crocus sativus L.), cinnamon (Cinnamomum verum J.Presl), flixweed [Descurainia sophia (L.) Webb ex Prantl], red feathers (Echium amoenum Fisch. & C.A.Mey.), and green tea [Camellia sinensis (L.) Kuntze] had the highest consumption rate among the majority (over 75%) of citizens of Rasht. The highest rate of perceived usefulness of medicinal herbs was related to their perceived role in healing diseases. The variable of importance of use of medicinal herbs had the strongest direct effect and the variables of perceived usefulness and attitude towards use had the second and third strongest direct effect on the acceptance of medicinal herbs' use at p acceptance of medicinal herbs and may serve as a benchmark for future research and evaluation concerning the use of medicinal herbs over time. For plant producers, more effective and targeted crop development should be encouraged, whereas for retailers better marketing and delivery strategies should be sought.

This method utilizes a newly developed empirical proton radiation-belt model, with the model output scaled by GPS in-situ measurements, to generate proton fluxes that cover a wide range of energies (50keV- 6MeV) and keep temporal features as well. The new proton radiation-belt model is developed based upon CEPPAD proton measurements from the Polar mission (1996 – 2007). Comparing to the de-facto standard empirical model of AP8, this model is not only based upon a new data set representative of the proton belt during the same period covered by GPS, but can also provide statistical information of flux values such as worst cases and occurrence percentiles instead of solely the mean values. The comparison shows quite different results from the two models and suggests that the commonly accepted error factor of 2 on the AP8 flux output over-simplifies and thus underestimates variations of the proton belt. Output fluxes from this new model along the GPS orbit are further scaled by the ns41 in-situ data so as to reflect the dynamic nature of protons in the outer radiation belt at geomagnetically active times. Derived daily proton fluxes along the GPS ns41 orbit, whose data files are delivered along with this report, are depicted to illustrate the trapped proton environment in the Medium-Earth Orbit. Uncertainties on those daily proton fluxes from two sources are evaluated: One is from the new proton-belt model that has error factors < ~3; the other is from the in-situ measurements and the error factors could be ~ 5.

Understanding Retailers’ Acceptance of Virtual Stores

OpenAIRE

Irene Y.L. Chen

2010-01-01

The acceptance of e-commerce among consumers has stimulated the rise of virtual stores. Increasing traditional retailers or people who do not have sufficient capital for maintaining a brick-and-mortar store have considered using virtual stores to reach global market. In the e-commerce literature, there has been rich research evidence concerning consumers’ acceptance of virtual stores. However, rigorous academic research on retailers’ acceptance of virtual stores is relatively scarce today. Th...

Study of niobium corrosion in alkaline medium

International Nuclear Information System (INIS)

Almeida, S.H. de.

1987-01-01

A comparative study of niobium electrochemical behaviour in NaOH and KOH solution, with concentrations between 0,5 and 6,1M is presented. The studies were done through electrochemicals assays, consisting in the corrosion potential and anodic and cathodic polarization curves, complemented by loss of mass experiments. The niobium anodic behaviour in alkaline medium is characterized by passivation occurrence, with a stable film formation. The Na oH solution in alkaline medium are more corrosible to niobium than the KOH solution. The loss of mass assays showed that the corrosion velocit is more dependente of hydroxide concentration in KOH medium than the NaOH medium. (C.G.C.) [pt

To determine perceptions of acceptable conducts amongst under and postgraduate optometry students and to compare them with students from other disciplines. Students (under/postgraduate) of optometry (n=156) and other courses (n=54) from University of Minho participated in a voluntary online questionnaire about perception of conducts, classifying as acceptable or unacceptable 15 academic or professional scenarios. 210 questionnaires were analyzed. Differences in perceptions were found between optometry under and postgraduates in scenario 5, Chi-square(2,156)=4.3, p=0.038, and scenario 7, Chi-square(2,156)=7.0, p=0.008 (both with cheating more acceptable for postgrads). Differences between under and postgraduates from other courses were found in scenario 9 (taking supplies from classroom more acceptable for undergrads), Chi-square(1,54)=5.0, p=0.025, and scenario 14 (forging a signature more acceptable for postgrads), Chi-square(1,54)=3.9, p=0.046. Differences between optometry and other courses undergraduates were observed in scenario 2 (plagiarism more acceptable for optometry undergrads), Chi-square(1,154)=8.3, p=0.004 and scenario 9 (taking supplies from classroom more acceptable for other undergrads), chi-square(1,54)=7.8, p=0.005. Differences between optometry and other courses postgraduates were observed in scenario 7, Chi-square(1,56)=5.8, p=0.016, scenario 10 (both with cheating more acceptable for optometry postgrads), chi-square(1,54)=8.1, p=0.004 and scenario 14 (forging a signature more acceptable for other postgrads), Chi-square(1,54)=6.1, p=0.026. Academic misconducts were mainly considered more acceptable than professional misconducts. Our results show that perceptions of acceptable conducts amongst optometry students are not very different from other students, and, against our initial prediction, do not show a general change in misconduct perception when students become more mature. Universities should pay more attention to this problem and take

1991 Acceptance priority ranking

International Nuclear Information System (INIS)

1991-12-01

The Standard Contract for Disposal of Spent Nuclear Fuel and/or High- Level Radioactive Waste (10 CFR Part 961) that the Department of Energy (DOE) has executed with the owners and generators of civilian spent nuclear fuel requires annual publication of the Acceptance Priority Ranking (APR). The 1991 APR details the order in which DOE will allocate Federal waste acceptance capacity. As required by the Standard Contract, the ranking is based on the age of permanently discharged spent nuclear fuel (SNF), with the owners of the oldest SNF, on an industry-wide basis, given the highest priority. the 1991 APR will be the basis for the annual allocation of waste acceptance capacity to the Purchasers in the 1991 Annual Capacity Report (ACR), to be issued later this year. This document is based on SNF discharges as of December 31, 1990, and reflects Purchaser comments and corrections, as appropriate, to the draft APR issued on May 15, 1991

Identification of permit and waste acceptance criteria provisions requiring modification for acceptance of commercial mixed waste

International Nuclear Information System (INIS)

1994-03-01

In October 1990, representatives of States and compact regions requested that the US Department of Energy (DOE) explore an agreement with host States and compact regions under which DOE would accept commercial mixed low-level radioactive waste (LLW) at DOE's own treatment and disposal facilities. A program for DOE management of commercial mixed waste is made potentially more attractive in light of the low commercial mixed waste volumes, high regulatory burdens, public opposition to new disposal sites, and relatively high cost of constructing commercial disposal facilities. Several studies were identified as essential in determining the feasibility of DOE accepting commercial mixed waste for disposal. The purpose of this report is to identify any current or proposed waste acceptance criteria (WAC) or Resource Conservation and Recovery Act (RCRA) provisions that would have to be modified for commercial mixed waste acceptance at specified DOE facilities. Following the introduction, Section 2 of this report (a) provides a background summary of existing and proposed mixed waste disposal facilities at each DOE site, and (b) summarizes the status of any RCRA Part B permit and WAC provisions relating to the disposal of mixed waste, including provisions relating to acceptance of offsite waste. Section 3 provides overall conclusions regarding the current status and permit modifications that must be implemented in order to grant DOE sites authority under their permits to accept commercial mixed waste for disposal. Section 4 contains a list of references

The aim of this study was to objectively assess the patients' acceptance for awake craniotomy in a group of neurosurgical patients, who underwent this procedure for removal of lesions in or close to eloquent brain areas. Patients acceptance for awake craniotomy under local anesthesia and conscious sedation was assessed by a formal questionnaire (PPP33), initially developed for general surgery patients. The results are compared to a group of patients who had brain surgery under general anesthesia and to previously published data. The awake craniotomy (AC) group consisted of 37 male and 9 female patients (48 craniotomies) with age ranging from 18 to 71 years. The general anesthesia (GA) group consisted of 26 male and 15 female patients (43 craniotomies) with age ranging from 26 to 83 years. All patients in the study were included in the questionnaire analysis. In comparison to GA the overall PPP33 score for AC was higher (p=0.07), suggesting better overall acceptance for AC. The subscale scores for AC were also significantly better compared to GA for the two subscales "postoperative pain" (p=0.02) and "physical disorders" (p=0.01) and equal for the other 6 subscales. The results of the overall mean score and the scores for the subscales of the PPP33 questionnaire verify good patients' acceptance for AC. Previous studies have shown good patients' acceptance for awake craniotomy, but only a few times using formal approaches. By utilizing a formal questionnaire we could verify good patient acceptance for awake craniotomy for the treatment of brain tumors in or close to eloquent areas. This is a novel approach that substantiates previously published experiences. Copyright © 2011 Elsevier B.V. All rights reserved.

Wey, Andrew; Salkowski, Nicholas; Kremers, Walter K; Schaffhausen, Cory R; Kasiske, Bertram L; Israni, Ajay K; Snyder, Jon J

2018-04-01

We developed a kidney offer acceptance decision tool to predict the probability of graft survival and patient survival for first-time kidney-alone candidates after an offer is accepted or declined, and we characterized the effect of restricting the donor pool with a maximum acceptable kidney donor profile index (KDPI). For accepted offers, Cox proportional hazards models estimated these probabilities using transplanted kidneys. For declined offers, these probabilities were estimated by considering the experience of similar candidates who declined offers and the probability that declining would lead to these outcomes. We randomly selected 5000 declined offers and estimated these probabilities 3 years post-offer had the offers been accepted or declined. Predicted outcomes for declined offers were well calibrated (offers been accepted, the probabilities of graft survival and patient survival were typically higher. However, these advantages attenuated or disappeared with higher KDPI, candidate priority, and local donor supply. Donor pool restrictions were associated with worse 3-year outcomes, especially for candidates with high allocation priority. The kidney offer acceptance decision tool could inform offer acceptance by characterizing the potential risk-benefit trade-off associated with accepting or declining an offer. © 2017 The American Society of Transplantation and the American Society of Transplant Surgeons.

Czerw, Aleksandra I; Bilińska, Magdalena; Deptała, Andrzej

2016-01-01

The paper presents the results of examining the level of acceptance of the illness in cancer patients using the Acceptance of Illness Scale (AIS). The study involved cancer patients treated at the Central Clinical Hospital of the Ministry the Interior in Warsaw in 2014. The questionnaire comprised basic demographic questions (socio-economic factors) and the AIS test estimating the level of illness acceptance in patients. For the group of patients in the research group, the arithmetic mean amounted to 27.56 points. The period of time that elapsed between the first cancer diagnosis and the start of the study did not influence the score of accepting illness. The acceptance of illness in patients diagnosed with metastases differed from the acceptance of illness by patients diagnosed with metastatic cancer. Females obtained the average of 29.59 in the AIS test, whereas the average in male patients was 26.17. The patients' age did not impact the AIS test. There were no differences in the AIS test results between a group of people with secondary education and a group of people with higher education. There were no differences in the AIS test results between employed individuals versus pensioners. The inhabitants of cities were characterized by the highest degree of acceptance of their health condition. The lowest degree of acceptance of illness was observed in the group with the lowest average incomes. In the group of married individuals the average degree of acceptance of illness amounted to 27.37 points. The average degree of acceptance of illness in patients that declared themselves as single amounted to 25.75. The average degree of acceptance of illness in the study group was 27.56 points, which is a relatively high level of acceptance of cancer. The main socio-economic factor, which influenced the AIS test results was whether metastases were diagnosed or not. There were no differences between patients in groups where the time that elapsed from the first diagnosis of

Physiologic correlates to background noise acceptance

Tampas, Joanna; Harkrider, Ashley; Nabelek, Anna

2004-05-01

Acceptance of background noise can be evaluated by having listeners indicate the highest background noise level (BNL) they are willing to accept while following the words of a story presented at their most comfortable listening level (MCL). The difference between the selected MCL and BNL is termed the acceptable noise level (ANL). One of the consistent findings in previous studies of ANL is large intersubject variability in acceptance of background noise. This variability is not related to age, gender, hearing sensitivity, personality, type of background noise, or speech perception in noise performance. The purpose of the current experiment was to determine if individual differences in physiological activity measured from the peripheral and central auditory systems of young female adults with normal hearing can account for the variability observed in ANL. Correlations between ANL and various physiological responses, including spontaneous, click-evoked, and distortion-product otoacoustic emissions, auditory brainstem and middle latency evoked potentials, and electroencephalography will be presented. Results may increase understanding of the regions of the auditory system that contribute to individual noise acceptance.

Residential proximinity, perceived and acceptable risk

International Nuclear Information System (INIS)

Rogers, G.O.

1984-01-01

This paper focuses on the relationship between the life experiences associated with residential proximity, and the perception and acceptability of the risks associated with generating electricity in nuclear power plants. Perceived risk is operationally defined in terms of estimated likelihood of occurrence, while acceptability of nuclear power is defined in terms of people's favorable or unfavorable opinions regarding nuclear power plants. In the context of a simple social-structural model of perceived and acceptable risk, four potential explanations for enhanced acceptability among those residentially proximate with nuclear facilities are examined: residents, through the experience of living with hazard, are reinforced toward assigning lower probabilities to the potential risks associated with nuclear facilities; the cognitive dissonance created by the acceptance of the risks associated with nuclear power is decreased by reducing perceived risk; nuclear neighbors are predisposed toward, educated about, and/or economically dependent upon nuclear power hence the more favorable attitudes toward it; nearby residents are systematically more altruistic--other oriented--than the general population and thus more willing to bear the risks associated with nuclear power

Effective medium theory principles and applications

CERN Document Server

Choy, Tuck C

2015-01-01

Effective medium theory dates back to the early days of the theory of electricity. Faraday in 1837 proposed one of the earliest models for a composite metal-insulator dielectric and around 1870 Maxwell and later Garnett (1904) developed models to describe a composite or mixed material medium. The subject has been developed considerably since and while the results are useful for predicting materials performance, the theory can also be used in a wide range of problems in physics and materials engineering. This book develops the topic of effective medium theory by bringing together the essentials of both the static and the dynamical theory. Electromagnetic systems are thoroughly dealt with, as well as related areas such as the CPA theory of alloys, liquids, the density functional theory etc., with applications to ultrasonics, hydrodynamics, superconductors, porous media and others, where the unifying aspects of the effective medium concept are emphasized. In this new second edition two further chapters have been...

We investigate the Casimir effect in the presence of a medium by quantizing the electromagnetic field in the presence of a magnetodielectric medium using the path-integral technique. For a given medium with definite electric and magnetic susceptibilities, explicit expressions for the Casimir force are obtained. The Lifshitz formula is recovered and in the absence of a medium the results tend to the original Casimir force between two conducting parallel plates immersed in the quantum electromagnetic vacuum.

A selective and differential medium for Vibrio harveyi.

Harris, L; Owens, L; Smith, S

1996-01-01

A new medium, termed Vibrio harveyi agar, has been developed for the isolation and enumeration of V. harveyi. It is possible to differentiate V. harveyi colonies from the colonies of strains representing 15 other Vibrio species with this medium. This medium has been shown to inhibit the growth of two strains of marine Pseudomonas spp. and two strains of marine Flavobacterium spp. but to allow the growth of Photobacterium strains. Colonies displaying typical V. harveyi morphology were isolated from the larval rearing water of a commercial prawn hatchery with V. harveyi agar as a primary isolation medium and were positively identified, by conventional tests, as V. harveyi. This agar displays great potential as a primary isolation medium and offers significant advantages over thiosulfate-citrate-bile salts-sucrose agar as a medium for differentiating V. harveyi from other marine and estuarine Vibrio species.

Marco, Iñigo; Feyerabend, Frank; Willumeit-Römer, Regine; Van der Biest, Omer

2016-01-01

This work studies the in vitro degradation of Mg alloys for bioabsorbable implant applications under near physiological conditions. For this purpose, the degradation behaviour of Mg alloys in Dulbecco's modified eagle medium (DMEM) which is a commonly used cell culture medium is analysed. Unfortunately, DMEM can be contaminated by microorganisms, acidifying the medium and accelerating the Mg degradation process by dissolution of protective degradation layers, such as (Mg_x,Ca_y)(PO_4)_z. In this paper the influence of sterilization by applying UV-C radiation and antibiotics (penicillin/streptomycin) is analysed with two implant material candidates: Mg–Gd and Mg–Ag alloys; and pure magnesium as well as Mg–4Y–3RE as a reference. - Highlights: • Contamination of DMEM by microorganisms increases the degradation rate of Mg. • Mg and its alloys show passivation during long term immersion tests in DMEM. • The use of a control sample position is essential to assess H_2 evolution in DMEM.

To test the compatibility of trisodium citrate, a catheter lock solution, with iodinated contrast medium. Iohexol, iobitridol, iodixanol, ioxaglate, ioxithalamate, iomeprol, and iopromide were tested. In all tests, 2 ml of contrast medium were mixed with 2 ml of trisodium citrate solution. Iodixanol and ioxaglate provoked a highly viscous gluelike precipitation when mixed with trisodium citrate. A brief transient precipitate was observed with iohexol, iomeprol, and ioxithalamate. Permanent precipitation occurred with iobitridol and iopromide. One must be aware of the potential for precipitation when contrast medium is mixed with trisodium citrate solution. Before trisodium citrate solution is injected, the catheter should be thoroughly flushed with saline if a contrast medium has previously been injected through it.

We use a Linear Boltzmann Transport (LBT) model coupled to the (3+1)D ideal hydrodynamic evolution in real time with fluctuating initial conditions to simulate both the transport of jet shower partons and jet-induced medium excitation. In this coupled approach, propagation of energetic shower partons are treated in the LBT model with the 3+1D hydrodynamic model providing the evolving bulk medium. Soft partons from both elastic and inelastic processes in the LBT are fed back into the medium as a source term in the 3+1D hydrodynamics leading to induced medium excitation. We study the effect of jet-induced medium excitation via γ-hadron correlation within this coupled LBT-hydro (CoLBT-hydro) approach.

van der Waals interactions in a magnetodielectric medium

2007-01-01

The van der Waals interaction between two ground-state atoms is calculated for two electrically or magnetically polarizable particles embedded in a dispersive magnetodielectric medium. Unlike previous calculations which infer the atom-atom interaction from the dilute-medium limit of the macroscopic, many-body van der Waals interaction, the interaction is calculated directly for the system of two atoms in a magnetodielectric medium. Two approaches are presented, the first based on the quantized electromagnetic field in a dispersive medium without absorption and the second on Green functions that allow for absorption. We show that the correct van der Waals interactions are obtained regardless of whether absorption in the host medium is explicitly taken into account

AN INVESTIGATION INTO MEDIUM-SIZED MULTINATIONAL ENTERPRISES

2013-09-01

Full Text Available The paper provides an investigation of medium-sized Italian industrial enterprises that have become multinational companies. It concetrates on the set of medium and medium-large enterprises who seem to grow more in foreign markets, either through exports or through foreign direct investment. The work also offers a descriptive empirical picture of the performance of medium-sized Italian multinationals, which is compared with the performance of large corporations. From this analysis, which is based on several data sources, it is possible to outline a profile regarding the medium-size italian multinational enterprises; the aim is to understand the complex strategy towards internationalization of these companies, where the dimension of production is important and, therefore, innovation has a key role. Also the commercial dimension is crucial, because it leads to point to the direct supervision of foreign markets and to look very carefully at the customers, offering them a wide range of services. Finally, the paper highlights some critical issues that the medium sized multinational enterprises have to face for competing: namely, the stagnant productivity, the high taxation, the insufficient institutional support for internationalization, the bureaucracy and its high costs, the lack of skilled human capital available in the labor market due to inadequate policy training.

Boothe, Chase; Strawderman, Lesley; Hosea, Ethan

2013-11-01

Inconsistencies among testing methods and results in previous research prompted this study that builds upon a systematic usability testing research framework to better understand how interface medium influences users' abilities to detect usability flaws in applications. Interface medium was tested to identify its effects on users' perceptions of usability and abilities to detect usability problems and severe usability problems. Results indicated that medium has no effect on users' abilities to detect usability problems or perceptions of usability. However, results did indicate an interaction between the medium and the tested application in which users were able to identify significantly more usability problems on a higher fidelity medium using a particular application. Results also indicated that as users' perceptions of an application's usability increases, the users are less able to detect usability problems in that application. Usability testing should begin early in the design process, even if low fidelity mediums will be used. Copyright © 2013 Elsevier Ltd and The Ergonomics Society. All rights reserved.

Differentiated influences of benefit and risk perceptions on nuclear power acceptance according to acceptance levels. Evidence from Korea

International Nuclear Information System (INIS)

Roh, Seungkook; Lee Jinwon

2017-01-01

The perceived benefit and risk of nuclear power generation have received considerable attention as determinants of the public's nuclear power acceptance. However, the contingency of the relative importance of these benefit and risk has been less explored. Using Korea as an example, this study explores the possibility that the relative importance of perceived benefit and risk on nuclear power acceptance depends on acceptance levels. Our results from latent class analysis and multinomial probit show that, in determining whether an individual shows a moderate level of nuclear power acceptance rather than a low level, perceived risk plays a dominant role compared to perceived benefit; however, regarding whether he/she shows a high level of nuclear power acceptance rather than a moderate level, this relative importance is reversed. These results carry practical implications for risk governance of nuclear power, particularly with regard to communication with the public. (author)

Simple Summary The objectives of this study were to compare the acceptance of different dry dog food products by consumers, determine consumer clusters for acceptance, and identify the characteristics of dog food that drive consumer acceptance. Pet owners evaluated dry dog food samples available in the US market. The results indicated that appearance of the sample, especially the color, influenced pet owner’s overall liking more than the aroma of the product. Abstract The objectives of this study were to compare the acceptance of different dry dog food products by consumers, determine consumer clusters for acceptance, and identify the characteristics of dog food that drive consumer acceptance. Eight dry dog food samples available in the US market were evaluated by pet owners. In this study, consumers evaluated overall liking, aroma, and appearance liking of the products. Consumers were also asked to predict their purchase intent, their dog’s liking, and cost of the samples. The results indicated that appearance of the sample, especially the color, influenced pet owner’s overall liking more than the aroma of the product. Overall liking clusters were not related to income, age, gender, or education, indicating that general consumer demographics do not appear to play a main role in individual consumer acceptance of dog food products.

Complications arise in the analysis of gunshot wounds to the maxillofacial region, when neither the projectile nor the gun is found at the crime scene. We simulated 5- and 15-cm firing distances at a human mandible to investigate the external morphology of entrance wounds based on fire range. The ammunition models, .40-caliber S&W, .380-caliber, and 9 × 19-mm Luger, were constructed with free-form NURBS surfaces. In a dynamic simulation, projectiles were fired against mandibular body 3D model at 5 and 15 cm. All entrance wounds presented oval aspect. Maximum diameter and von Mises stress values were 16.5 mm and 50.8 MPa, both for .40-caliber S&W fired at 5 cm. The maximum energy loss was 138.4 J for .40 S&W fired at 15 cm. In conclusion, the mandible was most affected by .40-caliber S&W and morphological differences were observable in holes caused by different incoming projectile calibers fired at different distances. © 2017 American Academy of Forensic Sciences.

Often, eHealth services are not accepted because of factors such as eHealth literacy or trust. Within this study, eHealthMonitor was evaluated in three European countries (Germany, Greece, and Poland) by medical professionals and laypersons with respect to numerous acceptance factors. Questionnaires were created on the basis of factors from literature and with the help of scales which have already been validated. A qualitative survey was conducted in Germany, Poland, and Greece. The eHealth literacy of all participants was medium/high. Laypersons mostly agreed that they could easily become skillful with eHealthMonitor and that other people thought that they should use eHealthMonitor. Amongst medical professionals, a large number were afraid that eHealthMonitor could violate their privacy or the privacy of their patients. Overall, the participants thought that eHealthMonitor was a good concept and that they would use it. The main hindrances to the use of eHealthMonitor were found in trust issues including data privacy. In the future, more research on the linkage of all measured factors is needed, for example, to address the question of whether highly educated people tend to mistrust eHealth information more than people with lower levels of education.

We discuss medium corrections of the nucleon-nucleon (NN) cross sections and their influence on direct reactions at intermediate energies ≳50 MeV/nucleon. The results obtained with free NN cross sections are compared with those obtained with a geometrical treatment of Pauli-blocking and Dirac-Bruecker methods. We show that medium corrections may lead to sizable modifications for collisions at intermediate energies and that they are more pronounced in reactions involving weakly bound nuclei.

Full Text Available HIV related stigma and discrimination is a known barrier for HIV prevention and care. We aimed to assess the relationship between socio-economic status (SES and HIV related stigma in Zimbabwe. This paper uses data from Project Accept, which examined the impact of community-based voluntary counseling and testing intervention on HIV incidence and stigma. Total of 2522 eligible participants responded to a psychometric assessment tool, which assessed HIV related stigma and discrimination attitudes on 4 point Likert scale. The tool measured three components of HIVrelated stigma: shame, blame and social isolation, perceived discrimination, and equity. Participants’ ownership of basic assets was used to assess the socio-economic status. Shame, blame and social isolation component of HIV related stigma was found to be significantly associated with medium [odds ratio (OR=1.73, P<0.01] and low SES (OR=1.97, P<0.01, indicating more stigmatizing attitudes by participants belonging to medium and low SES in comparison to high SES. For HIV related stigma and discrimination programs to be effective, they should take into account the socio-economic context of target population.

Full Text Available The possibility of application of malt extract as a source of carbohydrate in a medium for tea fungus was investigated. The beverage obtained on such medium was compared with that prepared in a traditional way with sucrose medium. The presence of easily adoptable sugars, glucose and fructose, as dominant in malt medium results in a very effective fermentation, which gives much more sour beverage for the same time and makes it possible to reduce the fermentation period. The obtained beverage has satisfactory sensorial characteristics.

The development of safe and efficacious preventive HIV vaccines offers the best long-term hope of controlling the AIDS pandemic. Nevertheless, suboptimal uptake of safe and efficacious vaccines that already exist suggest that HIV vaccine acceptability cannot be assumed, particularly among communities most vulnerable to HIV. The present study aimed to identify barriers and motivators to future HIV vaccine acceptability among low socioeconomic, ethnically diverse men and women in Los Angeles County. Participants completed a cross-sectional survey assessing their attitudes and beliefs regarding future HIV vaccines. Hypothetical HIV vaccine scenarios were administered to determine HIV vaccine acceptability. Two-sided t-tests were performed, stratified by gender, to examine the association between vaccine acceptability and potential barriers and motivators. Barriers to HIV vaccine acceptability differed between men and women. For women, barriers to HIV vaccine acceptability were related to their intimate relationships (p Motivators for women included the ability to conceive a child without worrying about contracting HIV (p Motivators for men included feeling safer with sex partners (p motivator for both men and women (p <0.10). Gender-specific interventions may increase vaccine acceptability among men and women at elevated risk for HIV infection. Among women, interventions need to focus on addressing barriers due to gendered power dynamics in relationships and discrimination in health care. Among men, education that addresses fears and misconceptions about adverse effects of HIV vaccination on health and the importance of vaccination as one component of integrated HIV prevention may increase vaccine acceptability.

The fastidious porcine respiratory pathogen Mycoplasma hyopneumoniae has proven difficult to culture since it was first isolated in 1965. A reliable solid medium has been particularly challenging. Moreover, clinical and pathological samples often contain the fast-growing M. hyorhinis which contaminates and overgrows M. hyopneumoniae in primary culture. The aim of this study was to optimise the culture medium for recovery of M. hyopneumoniae and to devise a medium for selection of M. hyopneumoniae from clinical samples also containing M. hyorhinis. The solid medium devised by Niels Friis was improved by use of Purified agar and incorporation of DEAE-dextran. Addition of glucose or neutralization of acidity in liquid medium with NaOH did not improve the final yield of viable organisms or alter the timing of peak viability. Analysis of the relative susceptibility of M. hyopneumoniae and M. hyorhinis strains to four antimicrobials showed that M. hyopneumoniae is less susceptible than M. hyorhinis to kanamycin. This was consistent in all UK and Danish strains tested. A concentration of 2μg/ml of kanamycin selectively inhibited the growth of all M. hyorhinis tested, while M. hyopneumoniae was able to grow. This forms the basis of an effective selective culture medium for M. hyopneumoniae. Copyright © 2016 The Authors. Published by Elsevier B.V. All rights reserved.

The aim of this work is to describe the relationship between self-esteem and characteristics of self image and acceptance of parents and the characteristics of their images in the perception of patients with anorexia nervosa. The test group consisted of 30 patients diagnosed with anorexia nervosa undergoing a treatment in the Department of Psychiatry of the Medical Academy in Lublin. The average age of the examined patients was 20 years. All patients had secondary education. In my work the ACL Gough and Heilbrun Adjectival Test was used which was completed by the examined women three times following the instruction: "I am", "my mother is", "my father is". As a result the actual images of the patients as well as of their mothers and fathers were obtained. The esteem rates were calculated by comparing the number of positive adjectives to the number of negative adjectives used by the patients to evaluate individual persons. The interdependencies between esteem rates and the characteristics of the actual images of these persons were determined based on the r-Pearson correlation. The results obtained indicated the existence of crucial statistic dependencies between the variables analysed and constituted the basis for the formulation of the following conclusions: 1. Patients are characterised by a low self-esteem and a low acceptance level of their parents. They accept their fathers in the smallest degree, compared to that their self-esteem is higher and the acceptance of their mothers is the highest. 2. Self-esteem is related in a significant way to the characteristics of self image such as: sense of responsibility, autonomy, ability to accomplish life objectives and establishing close relationships with other people. 3. The acceptance of their mothers is related to the characteristics typical of them such as: protectiveness, ability to establish and maintain positive interpersonal relationships, empathy and understanding the motives of their own behaviour and those of

Social risk elicits self-esteem differences in signature social motivations and behaviors during the relationship-initiation process. In particular, the present research tested the hypothesis that lower self-esteem individuals' (LSEs) motivation to avoid rejection leads them to self-protectively underestimate acceptance from potential romantic partners, whereas higher self-esteem individuals' (HSEs) motivation to promote new relationships leads them to overestimate acceptance. The results of 5 experiments supported these predictions. Social risk increased activation of avoidance goals for LSEs on a word-recall task but increased activation of approach goals for HSEs, as evidenced by their increased use of likeable behaviors. Consistent with these patterns of goal activation, even though actual acceptance cues were held constant across all participants, social risk decreased the amount of acceptance that LSEs perceived from their interaction partner but increased the amount of acceptance that HSEs perceived from their interaction partner. It is important to note that such self-esteem differences in avoidance goals, approach behaviors, and perceptions of acceptance were completely eliminated when social risk was removed.

We review chiral perturbation theory in some detail and construct interaction terms involving the Goldstone and the different non-Goldstone fields, in presence of external (classical) fields coupled to currents. The ensemble average of the two-point functions of the currents can now be expanded in terms of Feynman diagrams. We evaluate the one-loop diagrams in the neighbourhood of the respective poles to find the effective couplings and masses of the particles in medium. We also describe the virial formula for the self-energy of a particle in medium, giving its pole position. It proves useful if the scattering amplitude of the particle with particles in medium is known experimentally. (author)

Social acceptability is a determinant factor in the failure or success of the government's decisions about which electricity generation sources will satisfy the growing demand for energy. The main goal of this study was to validate a causal trust-acceptability model for electricity generation sources. In the model, social acceptance of an energy source is directly caused by perceived risk and benefit and also by social trust in regulatory agencies (both directly and indirectly, through perceived risk and benefit). Results from a web-based survey of Chilean university students demonstrated that data for energy sources that are controversial in Chilean society (fossil fuels, hydro, and nuclear power) fit the hypothesized model, whereas data for non conventional renewable energy sources (solar, wind, geothermal and tidal) did not. Perceived benefit had the greatest total effect on acceptability, thus emerging as a key predictive factor of social acceptability of controversial electricity generation sources. Further implications for regulatory agencies are discussed. - Highlights: ► We tested a causal trust-acceptability model for electricity generation sources in Chile. ► Data for controversial energy sources in the Chilean society (fossil fuels, hydro and nuclear power) fit the hypothesized model. ► Data for non conventional renewable energy sources did not fit the data. ► Perceived benefit showed the greatest total effect on acceptability.

There are few health promotion tools for urban Inuit, and there is a specific dearth of evaluations on such tools. The current study used a community-specific approach in the evaluation of a health promotion tool, based on an urban Inuit community's preferences of health knowledge sources and distribution strategies. In partnership with the Tungasuvvingat Inuit Family Health Team in Ottawa, a CD-Rom was developed featuring an Inuk Elder presenting prenatal health messages in both Inuktitut and English. Also, relevant evaluation materials were developed. Using a mixed methods approach, 40 participants completed interviews prior to viewing the CD-Rom and participated in a focus group at follow-up. Questionnaires were also completed pre- and post-viewing to assess changes between expectations and reactions in order to document acceptability. Significant increases were found on satisfaction, acceptability of medium and relevance of content ratings. Qualitative findings also included (a) interest, uncertainty and conditional interest prior to viewing; and (b) positive evaluations of the CD-Rom. This suggests that CD-Rom technology has the potential for health promotion for urban Inuit, and the community-specific evaluation approach yielded useful information.

E-learning is not going to work if the system is not used in accordance with user needs. User Interface is very important to encourage using the application. Many theories had discuss about user interface usability evaluation and technology acceptance separately, actually why we do not make it correlation between interface usability evaluation and user acceptance to enhance e-learning process. Therefore, the evaluation model for e-learning interface acceptance is considered important to investigate. The aim of this study is to propose the integrated e-learning user interface acceptance evaluation model. This model was combined some theories of e-learning interface measurement such as, user learning style, usability evaluation, and the user benefit. We formulated in constructive questionnaires which were shared at 125 English Language School (ELS) students. This research statistics used Structural Equation Model using LISREL v8.80 and MANOVA analysis.

2014-01-01

Across the globe, public acceptance of nuclear power is a crucial factor for governmental establishment of a nuclear energy program. Therefore, it is important to understand the determinants of public acceptance of nuclear power. This study examines the effects of knowledge, trust, risk, and benefit related factors on public acceptance of nuclear power across 19 countries. We consider three levels of public acceptance – strongly accept, reluctantly accept, and oppose – and classify countries into four groups according to the ratio of those three levels of public acceptance. Our results indicate that knowledge of nuclear inspection is more effective than trust in inspection authorities in creating stronger public acceptance among people in the countries with a high level of reluctant acceptance and a low level of strong acceptance, while trust in inspection authorities is more important than knowledge of nuclear inspection for the selection between opposition and reluctant acceptance in countries with a low level of reluctant acceptance and a high level of strong acceptance. Without grouping the countries, we found that trust in inspection authorities is crucial for the decision between opposition and reluctant acceptance. Additionally, the generation of electricity has the most positive effect on public acceptance of nuclear power. - Highlights: • We examine public acceptance (PA) of nuclear power across 19 countries. • Three levels of PA – strongly accept, reluctantly accept, and oppose – are considered. • Knowledge is most effective in creating stronger PA. • Trust is effective in shifting PA from opposition to reluctant acceptance. • Low risk and benefit of electricity generation enhance PA the most

In this article we show that when analyzing attitude towards lying in a cross-cultural setting, both the beneficiary of the lie (self vs other) and the context (private life vs. professional domain) should be considered. In a study conducted in Estonia, Ireland, Mexico, The Netherlands, Poland, Spain, and Sweden (N = 1345), in which participants evaluated stories presenting various types of lies, we found usefulness of relying on the dimensions. Results showed that in the joint sample the most acceptable were other-oriented lies concerning private life, then other-oriented lies in the professional domain, followed by egoistic lies in the professional domain; and the least acceptance was shown for egoistic lies regarding one's private life. We found a negative correlation between acceptance of a behavior and the evaluation of its deceitfulness.

Research purpose: To examine the nature of the relationships that exist between technology acceptance and frequency of mobile commerce usage amongst Generation Y consumers. Motivation for the study: The Generation Y cohort has emerged as an important age-group due to its economic contribution to the economy. It is therefore essential that their attitudes and behaviour continue to receive empirical introspection, particularly since mobile commerce has gathered momentum as an important and arguably, the most popular medium for commercial transactions. In a global space that is technology based, it becomes imperative to investigate the interplay between mobile commerce acceptance dimensions and frequency of use amongst Generation Ys. Research design, approach and method: A survey was conducted with the aid of a structured self-administered questionnaire with a view to collecting primary data from a sample consisting of 204 Generation Y consumers. Main findings: There were positive correlations between frequency of use and five mobile commerce acceptance dimensions. Cronbach Alpha values ranged between 0.714 and 0.898, thereby indicating high internal consistency amongst the subscales as well as within the entire survey instrument. Correlation coefficients ranged between 0.164 and 0.677 at both the p < 0.01 and p < 0.05 significance levels (2-tailed test, indicating very high levels of association amongst the subscales. Predictive validity of the five subscales and the variable frequency of use resulted in positive and statistically-significant results that were established at an adjusted R2 value of 0.674. Practical/managerial implications: Marketers and business practitioners are presented with practical insights into dimensions that enhance frequency of use of mobile commerce technology amongst Generation Y consumers. Furthermore, an increased usage of mobile commerce technologies is projected to have a stimulus effect on profitability, sustainability and loyalty

A dynamic voltage restorer (DVR) with selective harmonic compensation at medium voltage level

DEFF Research Database (Denmark)

Newman, M.J.; Holmes, D.G.; Nielsen, J.G.

2005-01-01

Dynamic voltage restorers (DVRs) are now becoming more established in industry to reduce the impact of voltage sags to sensitive loads. However, DVRs spend most of their time in standby mode, since voltage sags occur very infrequently, and hence their utilization is low. In principle, it would...... be advantageous if the series-connected inverter of a DVR could also be used to compensate for any steady-state load voltage harmonics, since this would increase the power quality "value-added" benefits to the grid system. However, before this can be done, consideration must be given to the control of steady......-state power through the DVR, the increased losses, and the low modulation depths at which the scheme must operate to achieve acceptable harmonic compensation performance. This paper presents a selective harmonic feedback control strategy that can be easily added to medium-voltage DVR systems to provide...

Overview of medium heterogeneity and transport processes

International Nuclear Information System (INIS)

Tsang, Y.; Tsang, C.F.

1993-11-01

Medium heterogeneity can have significant impact on the behavior of solute transport. Tracer breakthrough curves from transport in a heterogeneous medium are distinctly different from that in a homogeneous porous medium. Usually the shape of the breakthrough curves are highly non-symmetrical with a fast rise at early times and very long tail at late times, and often, they consist of multiple peaks. Moreover, unlike transport in a homogeneous medium where the same transport parameters describe the entire medium, transport through heterogeneous media gives rise to breakthrough curves which have strong spatial dependence. These inherent characteristics of transport in heterogeneous medium present special challenge to the performance assessment of a potential high level nuclear waste repository with respect to the possible release of radio nuclides to the accessible environment. Since an inherently desirable site characteristic for a waste repository is that flow and transport should be slow, then transport measurements in site characterization efforts will necessarily be spatially small and temporally short compare to the scales which are of relevance to performance assessment predictions. In this paper we discuss the role of medium heterogeneity in site characterization and performance assessment. Our discussion will be based on a specific example of a 3D heterogeneous stochastic model of a site generally similar to, the Aespoe Island, the site of the Hard Rock Laboratory in Southern Sweden. For our study, alternative 3D stochastic fields of hydraulic conductivities conditioned on ''point'' measurements shall be generated. Results of stochastic flow and transport simulations would be used to address the issues of (1) the relationship of tracer breakthrough with the structure of heterogeneity, and (2) the inference from small scale testing results to large scale and long term predictions

Microbiology laboratories continually strive to streamline and improve their urine culture algorithms because of the high volumes of urine specimens they receive and the modest numbers of those specimens that are ultimately considered clinically significant. In the current study, we quantitatively measured the impact of the introduction of CHROMagar Orientation (CO) medium into routine use in two hospital laboratories and compared it to conventional culture on blood and MacConkey agars. Based on data extracted from our Laboratory Information System from 2006 to 2011, the use of CO medium resulted in a 28% reduction in workload for additional procedures such as Gram stains, subcultures, identification panels, agglutination tests, and biochemical tests. The average number of workload units (one workload unit equals 1 min of hands-on labor) per urine specimen was significantly reduced (P < 0.0001; 95% confidence interval [CI], 0.5326 to 1.047) from 2.67 in 2006 (preimplementation of CO medium) to 1.88 in 2011 (postimplementation of CO medium). We conclude that the use of CO medium streamlined the urine culture process and increased bench throughput by reducing both workload and turnaround time in our laboratories. PMID:23363839

Charmonium propagation through a dense medium

Directory of Open Access Journals (Sweden)

Kopeliovich B.Z.

2015-01-01

Full Text Available Attenuation of a colourless c̄c dipole propagating with a large momentum through a hot medium originates from two sources, Debye screening (melting, and inelastic collisions with surrounding scattering centres (absorption. The former never terminates completely production of a bound charmonium in heavy ion collisions, even at very high temperatures. The latter, is controlled my the magnitude of the dipole cross section, related to the transport coefficient, which is the rate of transverse momentum broadening in the medium. A novel procedure of Lorentz boosting of the Schrödinger equation is developed, which allows to calculate the charmonium survival probability employing the path-integral technique, incorporating both melting and absorption. A novel mechanism of charmonium regeneration in a dense medium is proposed.

We study spatial meson correlation functions consisting of strange quarks, strange and charm quarks and charm quarks in (2 + 1)-flavor QCD using the highly improved staggered quark action. We find that the in-medium modification of the meson correlators decreases with increasing charm quark content and decreasing size. In particular, we find strong in-medium modification of φ and D s meson correlators around the chiral transition temperature T c , while J/ψ and η c correlators show strong in-medium modification only at temperatures of 1.4T c .

Acceptance and marketability of the food irradiation technology

International Nuclear Information System (INIS)

Sivinski, J.S.

1985-01-01

The food irradiation technology has been struggling for forty years for acceptance and utilization. The issue of consumer acceptance is addressed and judged not to be the critical factor in terms of priority and timing. The producing/processing marketing industries must first accept the technology for valid business or social reasons. If they become convinced that they cannot afford to pass up the technology, they will accept the process and offer irradiated products. These industries understand public acceptance and use professionals in market development and advertising to achieve consumption of their products. Consumer acceptance can best be developed by the food industry, while the research and development community, in concert with national and international agencies, can and should provide the industry with every assistance in reaching a consensus on the validity of food irradiation as an appropriate and useful technology

Understanding diversity: the importance of social acceptance.

Science.gov (United States)

Chen, Jacqueline M; Hamilton, David L

2015-04-01

Two studies investigated how people define and perceive diversity in the historically majority-group dominated contexts of business and academia. We hypothesized that individuals construe diversity as both the numeric representation of racial minorities and the social acceptance of racial minorities within a group. In Study 1, undergraduates' (especially minorities') perceptions of campus diversity were predicted by perceived social acceptance on a college campus, above and beyond perceived minority representation. Study 2 showed that increases in a company's representation and social acceptance independently led to increases in perceived diversity of the company among Whites. Among non-Whites, representation and social acceptance only increased perceived diversity of the company when both qualities were high. Together these findings demonstrate the importance of both representation and social acceptance to the achievement of diversity in groups and that perceiver race influences the relative importance of these two components of diversity. © 2015 by the Society for Personality and Social Psychology, Inc.

www.mitigasi-bencana.com as a knowledge management website created based on survey results in April-July 2014 in East Java and Central Java provinces, indicates a gap between the expectations and reality that exist in the services provided by the regional disaster management agency. Based on condition analysis, the gaps that occur can be reduced if the community has the understanding and knowledge of adequate disaster mitigation. The problem that arises later is whether the chosen technology solution is appropriate and acceptable to the public? The methodology used in this study using the Technology Acceptance Model development is the Unified Theory of Acceptance and Utilization of Technology (UTAUT). Feedback obtained from respondents KarangTaruna youth SelogedongBantul, www.mitigasi-bencana.com can be accepted by the respondents, but from processed data is obtained only UTAUT hypotheses on the relationship dimension eligible for Social Expectancy on the Attitude toward technology, which means the higher the perception of the Social Expectancy, the higher the perception of the Attitude toward technology. Because www.mitigasi-bencana.com is new socialized so that society still need time to explore content information and knowledge contained therein. To be accepted by user, a knowledge management application must prepare various aspects of Performance Expectancy, Effort Expectancy, Social Factors, Facilitating Conditions and Attitude.

Medium corrections to nucleon-nucleon interactions

International Nuclear Information System (INIS)

Dortmans, P.J.; Amos, K.

1990-01-01

The Bethe-Goldstone equations have been solved for both negative and positive energies to specify two nucleon G-matrices fully off of the energy shell. Medium correction effects of Pauli blocking and of the auxiliary potential are included in infinite matter systems characterized by fermi momenta in the range 0.5 fm -1 to 1.8 fm -1 . The Paris interaction is used as the starting potential in most calculations. Medium corrections are shown to be very significant over a large range of energies and densities. On the energy shell values of G-matrices vary markedly from those of free two nucleon (NN) t-matrices which have been solved by way of the Lippmann-Schwinger equation. Off of the energy shell, however, the free and medium corrected Kowalski-Noyes f-ratios rate are quite similar suggesting that a useful model of medium corrected G-matrices are appropriately scaled free NN t-matrices. The choice of auxiliary potential form is also shown to play a decisive role in the negative energy regime, especially when the saturation of nuclear matter is considered. 30 refs., 7 tabs., 7 figs

Phase object retrieval through scattering medium

Zhao, Ming; Zhao, Meijing; Wu, Houde; Xu, Wenhai

2018-05-01

Optical imaging through a scattering medium has been an interesting and important research topic, especially in the field of biomedical imaging. However, it is still a challenging task due to strong scattering. This paper proposes to recover the phase object behind the scattering medium from one single-shot speckle intensity image using calibrated transmission matrices (TMs). We construct the forward model as a non-linear mapping, since the intensity image loses the phase information, and then a generalized phase retrieval algorithm is employed to recover the hidden object. Moreover, we show that a phase object can be reconstructed with a small portion of the speckle image captured by the camera. The simulation is performed to demonstrate our scheme and test its performance. Finally, a real experiment is set up, we measure the TMs from the scattering medium, and then use it to reconstruct the hidden object. We show that a phase object of size 32 × 32 is retrieved from 150 × 150 speckle grains, which is only 1/50 of the speckles area. We believe our proposed method can benefit the community of imaging through the scattering medium.

Hanford Site solid waste acceptance criteria

International Nuclear Information System (INIS)

Ellefson, M.D.

1998-01-01

Order 5820.2A requires that each treatment, storage, and/or disposal facility (referred to in this document as TSD unit) that manages low-level or transuranic waste (including mixed waste and TSCA PCB waste) maintain waste acceptance criteria. These criteria must address the various requirements to operate the TSD unit in compliance with applicable safety and environmental requirements. This document sets forth the baseline criteria for acceptance of radioactive waste at TSD units operated by WMH. The criteria for each TSD unit have been established to ensure that waste accepted can be managed in a manner that is within the operating requirements of the unit, including environmental regulations, DOE Orders, permits, technical safety requirements, waste analysis plans, performance assessments, and other applicable requirements. Acceptance criteria apply to the following TSD units: the Low-Level Burial Grounds (LLBG) including both the nonregulated portions of the LLBG and trenches 31 and 34 of the 218-W-5 Burial Ground for mixed waste disposal; Central Waste Complex (CWC); Waste Receiving and Processing Facility (WRAP); and T Plant Complex. Waste from all generators, both from the Hanford Site and from offsite facilities, must comply with these criteria. Exceptions can be granted as provided in Section 1.6. Specific waste streams could have additional requirements based on the 1901 identified TSD pathway. These requirements are communicated in the Waste Specification Records (WSRds). The Hanford Site manages nonradioactive waste through direct shipments to offsite contractors. The waste acceptance requirements of the offsite TSD facility must be met for these nonradioactive wastes. This document does not address the acceptance requirements of these offsite facilities

Jet multiplicity distributions: medium dependence in MLLA

International Nuclear Information System (INIS)

Armesto, Nestor; Pajares, Carlos; Quiroga-Arias, Paloma

2009-01-01

We study the medium dependence of the multiplicity distributions in the modified leading logarithmic approximation. We focus in the enhancement in the number of branchings as the partons travel trough a dense medium created in a heavy-ion collision. We study the effect of a higher number of splittings in some jet observables by introducing the medium as a constant (f med ) in the splitting functions. Having as our ansatz for the quark and gluon jets mean multiplicities left angle n G right angle =e γy and left angle n Q right angle =r -1 e γy , we study in an analytic approach the dependence with the medium (f med ) of the anomalous dimension (γ), the multiplicity ratio (r), and so the mean multiplicities. We also obtain the higher-order moments of the multiplicity distribution, what allows us to study its dispersion. (orig.)

Local acceptance of existing biogas plants in Switzerland

Soland, Martin; Steimer, Nora; Walter, Götz

2013-01-01

After the Swiss government's decision to decommission its five nuclear power plants by 2035, energy production from wind, biomass, biogas and photovoltaic is expected to increase significantly. Due to its many aspects of a direct democracy, high levels of public acceptance are necessary if a substantial increase in new renewable energy power plants is to be achieved in Switzerland. A survey of 502 citizens living near 19 biogas plants was conducted as the basis for using structural equation modeling to measure the effects of perceived benefits, perceived costs, trust towards the plant operator, perceived smell, information received and participation options on citizens’ acceptance of “their” biogas plant. Results show that local acceptance towards existing biogas power plants is relatively high in Switzerland. Perceived benefits and costs as well as trust towards the plant operator are highly correlated and have a significant effect on local acceptance. While smell perception and information received had a significant effect on local acceptance as well, no such effect was found for participation options. Reasons for the non-impact of participation options on local acceptance are discussed, and pathways for future research are presented. - Highlights: • Acceptance of biogas plants by local residents in Switzerland is relatively high. • Local acceptance is highly affected by perceived outcomes and citizens’ trust. • Smell perception increases perceived costs and reduces perceived benefits and trust. • Information offers reduce perceived costs and increase trust and perceived benefits. • Participation offers do not have any effect on local acceptance

Nowadays, the information access in communication networks is widely explored due to the increase of Internet users. In this context, the PLC (Power Line Communication) technology is an alternative for data transmission. This technology is based on the usage of transmission/distribution power lines for data transmission. However there are some problems related to the usage of this technology: adequate data transmission rates and generation of acceptable levels of electromagnetic interference (EMI). This work had the objective of studying the performance of PLC systems in medium voltage electrical networks, through the assess of data transmission rates and the generated EMI. Tests were carried out in a test field that corresponded to a medium voltage electrical network and the obtained results show that, under some circumstances, the PLC system does not reach the existent technical recommendations.

2014-01-01

User acceptance of information technology has been a significant area of research for more than two decades in the field of information technology. This study assessed the acceptance of information technology in the context of Health Information Management (HIM) by utilizing Technology Acceptance Model (TAM) which was modified and applied to assess user acceptance of health information technology as well as viability of TAM as a research construct in the context of HIM. This was a descriptive- analytical study in which a sample of 187 personnel from a population of 363 personnel, working in medical records departments of hospitals affiliated to Tehran University of Medical Sciences, was selected. Users' perception of applying information technology was studied by a researcher-developed questionnaire. Collected data were analyzed by SPSS software (version16) using descriptive statistics and regression analysis. The results suggest that TAM is a useful construct to assess user acceptance of information technology in the context of HIM. The findings also evidenced the perceived ease of use (PEOU) and perceived usefulness (PE) were positively associated with favorable users' attitudes towards HIM. PU was relatively more associated (r= 0.22, p = 0.05) than PEOU (r = 0.014, p = 0.05) with favorable user attitudes towards HIM. Users' perception of usefulness and ease of use are important determinants providing the incentive for users to accept information technologies when the application of a successful HIM system is attempted. The findings of the present study suggest that user acceptance is a key element and should subsequently be the major concern of health organizations and health policy makers.

2009-03-01

In a sample of 170 youngsters, the effect of two versions of a public service announcement (PSA) threat appeal against speeding, placed in four different contexts, on evoked fear, perceived threat (severity and probability of occurrence), perceived response efficacy and self-efficacy, message involvement and anti-speeding attitude and anti-speeding intention is investigated. Evoked fear and perceived threat and efficacy independently influence message involvement. Message involvement is a full mediator between evoked fear, perceived threat and efficacy perception on the one hand, and attitudes towards the message and behavioral intention to accept the message on the other. Speeding experience has a significantly negative impact on anti-speeding attitudes. Message and medium context threat levels and context thematic congruency have a significant effect on evoked fear and to a lesser extent on perceived threat.

Acceptance, acceptability, and energy consensus. Can there still be a consensus on nuclear energy?

International Nuclear Information System (INIS)

Renn, O.

1995-01-01

The question of public acceptance of nuclear energy has for years fueled the discussion on social issues. Denial of this acceptance has without doubt delayed, if not altogether prevented, the further development of nuclear energy during the past two decades. Public perception of nuclear energy is still dominated by resent. In the eyes of the German public it is a dangerous and unacceptable technology that deserves to be substituted as soon as possible. The necessity of this is widely agreed, the only unsettled question being how fast it must happen. Sociologists are often reproached for having only created the acceptance problems they purport to analyse. All sociology can do is describe our reality and make suggestions how to cope with social problems more effectively. The sociologist is the herald of social reality: he should neither gloss over nor dramatise things but rather present a real picture of what is happening. With this premise in mind the author attempts to point out possibilities of and limits to a consensus on the valuation of energy systems, particularly that of nuclear energy. (orig./UA) [de

Medium properties and total energy coupling in underground explosions

International Nuclear Information System (INIS)

Kurtz, S.R.

1975-01-01

A phenomenological model is presented that allows the direct calculation of the effects of variations in medium properties on the total energy coupling between the medium and an underground explosion. The model presented is based upon the assumption that the shock wave generated in the medium can be described as a spherical blast wave at early times. The total energy coupled to the medium is then simply the sum of the kinetic and internal energies of this blast wave. Results obtained by use of this model indicate that the energy coupling is more strongly affected by the medium's porosity than by its water content. These results agree well with those obtained by summing the energy deposited by the blast wave as a function of range

2009-01-01

We undertook a survey to determine the public acceptance of medical radiation exposure throughout Japan, and 1,357 responses (67.9% response rate) were obtained using a two-stage systematic stratified random sampling method. The acceptance of exposure of children was generally similar to that of adults. For each of the attributes, 45-60% of the participants were accepting of exposure for cancer treatment and diagnosis, but only 30% were accepting of exposure for X-ray diagnoses of bone fractures and dental caries. In general, the presence of a child did not markedly affect women's acceptance of exposure. Factor analyses identified 3 factors influencing the acceptance of child exposure: symptomatic diseases to determine treatment, the possibility of high-risk diseases (or major organ diseases), and the association with cancer. Cluster analysis showed 4 clusters: a positive group regarding children's exposure for the diagnosis of bone fractures and dental caries (12.9% of all participants), a positive group for major organ disease and cancer (15.5%), a negative group excluding cancer (55.2%), and a positive group for all cases (16.4%). The cluster distributions revealed that mothers with 10- to 18-year-old firstborn children showed a tendency to accept the medical radiation exposure of their children in all cases. (author)

Toward an acceptable nuclear future

Weinberg, A.M.

1977-11-01

The nuclear option is in danger of being foreclosed. The trend toward antinuclearism may be reversed if concerns about low-level radiation insult can be shown ultimately to be without foundation; evidence for this speculation is presented. Nevertheless it is suggested that the nuclear enterprise itself must propose new initiatives to increase the acceptability of nuclear energy. A key element of an acceptable nuclear future is cluster siting of reactors. This siting plan might be achieved by confining new reactors essentially to existing sites

Hand hygiene (HH) prevents harmful contaminants spreading in settings including domestic, health care and food handling. Strategies to improve HH range from behavioural techniques through to automated sinks that ensure hand surface cleaning. This study aimed to assess user experience and acceptance towards a new automated sink, compared to a normal sink. An adapted version of the technology acceptance model (TAM) assessed each mode of handwashing. A within-subjects design enabled N = 46 participants to evaluate both sinks. Perceived Ease of Use and Satisfaction of Use were significantly lower for the automated sink, compared to the conventional sink (p technology. We provide recommendations for future HH technology development to contribute a positive user experience, relevant to technology developers, ergonomists and those involved in HH across all sectors. Practitioner Summary: The need to facilitate timely, effective hand hygiene to prevent illness has led to a rise in automated handwashing systems across different contexts. User acceptance is a key factor in system uptake. This paper applies the technology acceptance model as a means to explore and optimise the design of such systems.

Factors Potentially Influencing Student Acceptance of Biological Evolution

Science.gov (United States)

Wiles, Jason R.

This investigation explored scientific, religious, and otherwise nonscientific factors that may influence student acceptance of biological evolution and related concepts, how students perceived these factors to have influenced their levels of acceptance of evolution and changes therein, and what patterns arose among students' articulations of how their levels of acceptance of evolution may have changed. This exploration also measured the extent to which students' levels of acceptance changed following a treatment designed to address factors identified as potentially affecting student acceptance of evolution. Acceptance of evolution was measured using the MATE instrument (Rutledge and Warden, 1999; Rutledge and Sadler, 2007) among participants enrolled in a secondary-level academic program during the summer prior to their final year of high school and as they transitioned to the post-secondary level. Student acceptance of evolution was measured to be significantly higher than pre-treatment levels both immediately following and slightly over one year after treatment. Qualitative data from informal questionnaires, from formal course evaluations, and from semi-structured interviews of students engaged in secondary level education and former students at various stages of post-secondary education confirmed that the suspected factors were perceived by participants to have influenced their levels of acceptance of evolution. Furthermore, participant reports provided insight regarding the relative effects they perceived these factors to have had on their evolution acceptance levels. Additionally, many participants reported that their science teachers in public schools had avoided, omitted, or denigrated evolution during instruction, and several of these students expressed frustration regarding what they perceived to have been a lack of education of an important scientific principle. Finally, no students expressed feelings of being offended by having been taught about

2010-12-01

The property of linear and circular birefringence at each point of the optical medium has been evaluated here from differential matrix N using the Jones calculus. This matrix lies on the OAM sphere for l = 1 orbital angular momentum. The geometric phase is developed by twisting the medium uniformly about the direction of propagation of the light ray. The circular birefringence of the medium, is visualized through the solid angle and the angular twist per unit thickness of the medium, k, that is equivalent to the topological charge of the optical element.

Medium energy ion scattering (MEIS)

International Nuclear Information System (INIS)

Dittmann, K.; Markwitz, A.

2009-01-01

This report gives an overview about the technique and experimental study of medium energy ion scattering (MEIS) as a quantitative technique to determine and analyse the composition and geometrical structure of crystalline surfaces and near surface-layers by measuring the energy and yield of the backscattered ions. The use of a lower energy range of 50 to 500 keV accelerated ions impinging onto the target surface and the application of a high-resolution electrostatic energy analyser (ESA) makes medium energy ion scattering spectroscopy into a high depth resolution and surface-sensitive version of RBS with less resulting damage effects. This report details the first steps of research in that field of measurement technology using medium energetic backscattered ions detected by means of a semiconductor radiation detector instead of an ESA. The study of medium energy ion scattering (MEIS) has been performed using the 40 keV industrial ion implanter established at GNS Sciences remodelled with supplementary high voltage insulation for the ion source in order to apply voltages up to 45 kV, extra apertures installed in the beamline and sample chamber in order to set the beam diameter accurately, and a semiconductor radiation detector. For measurement purposes a beam of positive charged helium ions accelerated to an energy of about 80 keV has been used impinging onto target surfaces of lead implanted into silicon (PbSi), scandium implanted into aluminium (ScAl), aluminium foil (Al) and glassy carbon (C). First results show that it is possible to use the upgraded industrial implanter for medium energy ion scattering. The beam of 4 He 2+ with an energy up to 88 keV has been focussed to 1 mm in diameter. The 5 nA ion beam hit the samples under 2 x 10 -8 mbar. The results using the surface barrier detector show scattering events from the samples. Cooling of the detector to liquid nitrogen temperatures reduced the electronic noise in the backscattering spectrum close to zero. A

Isogeometric frictionless contact analysis with the third medium method

Science.gov (United States)

Kruse, R.; Nguyen-Thanh, N.; Wriggers, P.; De Lorenzis, L.

2018-01-01

This paper presents an isogeometric formulation for frictionless contact between deformable bodies, based on the recently proposed concept of the third medium. This concept relies on continuum formulations not only for the contacting bodies but also for a fictitious intermediate medium in which the bodies can move and interact. Key to the formulation is a suitable definition of the constitutive behavior of the third medium. In this work, based on a number of numerical tests, the role of the material parameters of the third medium is systematically assessed. We also assess the rate of spatial convergence for higher-order discretizations, stemming from the regularization of the non-smooth contact problem inherent to the third medium approach. Finally, problems with self contact are considered and turn out to be an attractive application of the method.

Ushida, Yasunori

1993-01-01

Japan Nuclear Fuel Limited, incorporated by mainly ten Japanese utilities, engages in constructing and operating nuclear fuel cycle facilities such as reprocessing, uranium enrichment and low level radioactive waste disposal at Rokkasho village in Aomori prefecture, 600 kilometers north of Tokyo, where is the most northern part of Honshu island. This presentation deals with the situation concerning the Rokkasho project and our public acceptance activities. The expansion of anti nuclear movement was spread not only Aomori prefecture but also all over Japan, affected strongly by the Chernobyl accident. In 1988,16 anti-nuclear groups including labor-union organized a committee for the purpose of a campaign to collect signatures for opposing nuclear fuel cycle facilities. Those groups brought in a lawsuit against the Japan Nuclear Fuel Limited, for stopping the construction of enrichment plant. Facing furious anti nuclear fuel cycle movements in Aomori prefecture, the Federation of Electric Power Companies decided to re strengthen the public acceptance activities and established the Nuclear Fuel Joint head office together with Japan Nuclear Fuel Service Co.and Japan Nuclear Fuel Industry Co. To this new organization many excellent members were dispatched from all electric power companies. The target area for public acceptance activities expanded from the surrounding area to all area of Aomori prefecture. The first policy of public acceptance activities is 'Appealing by face to face' which means the direct personal contact with people being anxious about nuclear fuel cycle facilities. The second main policy is 'Seeing the plant itself is better than persuading orally.' Survey conducted by a newspaper company in respect with the public acceptance of Rokkasho project in July 1989 July 1992 showed a favorable change of the public acceptance. However, one also has to recognize that most of people still have anxiety about the nuclear fuel cycle facilities and we shall

Consumer Acceptance of Dry Dog Food Variations

Directory of Open Access Journals (Sweden)

Brizio Di Donfrancesco

2014-06-01

Full Text Available The objectives of this study were to compare the acceptance of different dry dog food products by consumers, determine consumer clusters for acceptance, and identify the characteristics of dog food that drive consumer acceptance. Eight dry dog food samples available in the US market were evaluated by pet owners. In this study, consumers evaluated overall liking, aroma, and appearance liking of the products. Consumers were also asked to predict their purchase intent, their dog’s liking, and cost of the samples. The results indicated that appearance of the sample, especially the color, influenced pet owner’s overall liking more than the aroma of the product. Overall liking clusters were not related to income, age, gender, or education, indicating that general consumer demographics do not appear to play a main role in individual consumer acceptance of dog food products.

Acceptable-risk decisions are an essential step in the management of technological hazards. In many situations, they constitute the weak (or missing) link in the management process. The absence of an adequate decision-making methodology often produces indecision, inconsistency, and dissatisfaction. The result is neither good for hazard management nor good for society. This report offers a critical analysis of the viability of various approaches as guides to acceptable-risk decisions. This report seeks to define acceptable-risk decisions and to examine some frequently proposed, but inappropriate, solutions. 255 refs., 22 figs., 25 tabs.

Jung, Mary-Louise; Loria, Karla

2010-01-01

Objective: To investigate older people’s acceptance of e-health services, in order to identify determinants of, and barriers to, their intention to use e-health. Method: Based on one of the best-established models of technology acceptance, Technology Acceptance Model (TAM), in-depth exploratory interviews with twelve individuals over 45 years of age and of varying backgrounds are conducted. Results: This investigation could find support for the importance of usefulness and perceived ease of use of the e-health service offered as the main determinants of people’s intention to use the service. Additional factors critical to the acceptance of e-health are identified, such as the importance of the compatibility of the services with citizens’ needs and trust in the service provider. Most interviewees expressed positive attitudes towards using e-health and find these services useful, convenient, and easy to use. Conclusion: E-health services are perceived as a good complement to traditional health care service delivery, even among older people. These people, however, need to become aware of the e-health alternatives that are offered to them and the benefits they provide. PMID:21289860

High-harmonic generation in a dense medium

International Nuclear Information System (INIS)

Strelkov, V.V.; Platonenko, V.T.; Becker, A.

2005-01-01

The high-harmonic generation in a plasma or gas under conditions when the single-atom response is affected by neighboring ions or atoms of the medium is studied theoretically. We solve numerically the three-dimensional Schroedinger equation for a single-electron atom in the combined fields of the neighboring particles and the laser, and average the results over different random positions of the particles using the Monte Carlo method. Harmonic spectra are calculated for different medium densities and laser intensities. We observe a change of the harmonic properties due to a random variation of the harmonic phase induced by the field of the medium, when the medium density exceeds a certain transition density. The transition density is found to depend on the harmonic order, but it is almost independent of the fundamental intensity. It also differs for the two (shorter and longer) quantum paths. The latter effect leads for ionic densities in the transition regime to a narrowing of the harmonic lines and a shortening of the attosecond pulses generated using a group of harmonics

Acceptance of dying: a discourse analysis of palliative care literature.

Science.gov (United States)

Zimmermann, Camilla

2012-07-01

The subject of death denial in the West has been examined extensively in the sociological literature. However, there has not been a similar examination of its "opposite", the acceptance of death. In this study, I use the qualitative method of discourse analysis to examine the use of the term "acceptance" of dying in the palliative care literature from 1970 to 2001. A Medline search was performed by combining the text words "accept or acceptance" with the subject headings "terminal care or palliative care or hospice care", and restricting the search to English language articles in clinical journals discussing acceptance of death in adults. The 40 articles were coded and analysed using a critical discourse analysis method. This paper focuses on the theme of acceptance as integral to palliative care, which had subthemes of acceptance as a goal of care, personal acceptance of healthcare workers, and acceptance as a facilitator of care. For patients and families, death acceptance is a goal that they can be helped to attain; for palliative care staff, acceptance of dying is a personal quality that is a precondition for effective practice. Acceptance not only facilitates the dying process for the patient and family, but also renders care easier. The analysis investigates the intertextuality of these themes with each other and with previous texts. From a Foucauldian perspective, I suggest that the discourse on acceptance of dying represents a productive power, which disciplines patients through apparent psychological and spiritual gratification, and encourages participation in a certain way to die.

2016-04-01

Aerobic production of rhamnolipid by Pseudomonas aeruginosa was extensively studied. But effect of medium composition on anaerobic production of rhamnolipid by P. aeruginosa was unknown. A simplifying medium facilitating anaerobic production of rhamnolipid is urgently needed for in situ microbial enhanced oil recovery (MEOR). Medium factors affecting anaerobic production of rhamnolipid were investigated using P. aeruginosa SG (Genbank accession number KJ995745). Medium composition for anaerobic production of rhamnolipid by P. aeruginosa is different from that for aerobic production of rhamnolipid. Both hydrophobic substrate and organic nitrogen inhibited rhamnolipid production under anaerobic conditions. Glycerol and nitrate were the best carbon and nitrogen source. The commonly used N limitation under aerobic conditions was not conducive to rhamnolipid production under anaerobic conditions because the initial cell growth demanded enough nitrate for anaerobic respiration. But rhamnolipid was also fast accumulated under nitrogen starvation conditions. Sufficient phosphate was needed for anaerobic production of rhamnolipid. SO4(2-) and Mg(2+) are required for anaerobic production of rhamnolipid. Results will contribute to isolation bacteria strains which can anaerobically produce rhamnolipid and medium optimization for anaerobic production of rhamnolipid. Based on medium optimization by response surface methodology and ions composition of reservoir formation water, a simplifying medium containing 70.3 g/l glycerol, 5.25 g/l NaNO3, 5.49 g/l KH2PO4, 6.9 g/l K2HPO4·3H2O and 0.40 g/l MgSO4 was designed. Using the simplifying medium, 630 mg/l of rhamnolipid was produced by SG, and the anaerobic culture emulsified crude oil to EI24 = 82.5 %. The simplifying medium was promising for in situ MEOR applications.

2010-04-01

Full Text Available Abstract Background The aim of this study was to validate a Spanish version of the Chronic Pain Acceptance Questionnaire (CPAQ. Pain acceptance is the process of giving up the struggle with pain and learning to live a worthwhile life despite it. The Chronic Pain Acceptance Questionnaire (CPAQ is the questionnaire most often used to measure pain acceptance in chronic pain populations. Methods A total of 205 Spanish patients diagnosed with fibromyalgia syndrome who attended our pain clinic were asked to complete a battery of psychometric instruments: the Pain Visual Analogue Scale (PVAS for pain intensity, the Hospital Anxiety and Depression Scale (HADS, the Medical Outcome Study Short Form 36 (SF-36, the Pain Catastrophising Scale (PCS and the Fibromyalgia Impact Questionnaire (FIQ. Results Analysis of results showed that the Spanish CPAQ had good test-retest reliability (intraclass correlation coefficient 0.83 and internal consistency reliability (Cronbach's α: 0.83. The Spanish CPAQ score significantly correlated with pain intensity, anxiety, depression, pain catastrophising, health status and physical and psychosocial disability. The Scree plot and a Principal Components Factor analysis confirmed the same two-factor construct as the original English CPAQ. Conclusion The Spanish CPAQ is a reliable clinical assessment tool with valid construct validity for the acceptance measurement among a sample of Spanish fibromyalgia patients. This study will make it easier to assess pain acceptance in Spanish populations with fibromyalgia.

Risk of application of contrast medium in computed tomography

Wende, S.; Speck, U.

1981-06-01

The paper deals with the risk associated with the application of contrast medium in CT. The risk is to be seen in intolerance reactions, such as allergic or circulatory reactions and neurotoxic side-effects. In this paper the problems of renal failure caused by the injection of contrast medium are given special attention. Furthermore an iodine-induced hyperthyreosis might result. Especially the possible disturbance of the kidney function means that contrast medium should not be applied arbitrarily and that the examination should be done only by experienced staff. Furthermore the indication for the application of contrast medium in CT should be strictly qualified.

Stern, David L; Sucena, Elio

2012-01-01

The Drosophila cuticle carries a rich array of morphological details. Thus, cuticle examination has had a central role in the history of genetics. This protocol describes a procedure for mounting adult cuticles in Hoyer's medium, a useful mountant for both larval and adult cuticles. The medium digests soft tissues rapidly, leaving the cuticle cleared for observation. In addition, samples can be transferred directly from water to Hoyer's medium. However, specimens mounted in Hoyer's medium degrade over time. For example, the fine denticles on the larval dorsum are best observed soon after mounting; they begin to fade after 1 week, and can disappear completely after several months. More robust features, such as the ventral denticle belts, will persist for a longer period of time. Because adults cannot profitably be mounted whole in Hoyer's medium, some dissection is necessary.

2011-06-01

The Internet is increasingly used to deliver treatment programs for common mental disorders. However, little is known about the acceptability of online interventions. The present study used an online survey to explore levels of acceptability of Internet-based treatment programs for anxiety and depression. Visitors to websites operated by the Clinical Research Unit for Anxiety and Depression (CRUfAD), were invited to complete an online questionnaire during 16 weeks in 2008. Of 1543 people who began the survey, 1104 (72%) Australian health professionals and lay people completed it. Internet treatment programs for people with mild or moderate symptoms were more acceptable than programs for people with severe symptoms. There were no differences between health professionals and non-health professionals in acceptability ratings. As expected, previous users of Internet treatments reported significantly greater acceptability and preference for Internet treatments than non-users. Respondents rated Internet-based treatment programs as acceptable, with higher ratings from previous users. In order to facilitate implementation, program developers need to implement strategies for increasing knowledge about the efficacy and effectiveness of such programs, and engage therapists and consumers in establishing ethical and professional guidelines for their safe and responsible use.

Pion valence distributions in nuclear medium and vacuum are studied in a light-front constituent quark model. The in-medium input for studying the pion properties is calculated by the quark-meson coupling model. We find that the in-medium pion valence distribution, as well as the in-medium pion valence wave function, are substantially modified at normal nuclear matter density, due to the reduction in the pion decay constant.

Approaches to gaining public acceptance of repository siting

International Nuclear Information System (INIS)

Numark, N.J.; Wonder, E.F.

1989-01-01

An eight-country survey reveals a diversity of strategies that have been followed for siting radioactive waste repositories, as well as a range of levels of public acceptance of siting efforts. Although the strategies are not necessarily interchangeable from country to country, certain inferences may be drawn from worldwide siting experience regarding ways to maximize public acceptance. Furthermore, waste management organizations in these countries have placed varying amounts of stock in technical review by outside experts and in a range of communications strategies as means of improving public acceptance. Our survey of worldwide experience also allows some general observations to be made regarding the effectiveness of these efforts. Combining a strategy that elevates public acceptance to part of the overall mission of siting a waste management facility with strategies for appropriate communications and external technical review may be necessary and sufficient for gaining improvements in public acceptance of proposed repository sites

Improving acceptance in wind power planning

1996-01-01

This paper presents important factors and planning procedures for public acceptance of wind power. Opinion surveys in Sweden show that acceptance is connected to the concept of utility rather than the aesthetic values. If wind turbines are confined by the authorities to marginal areas they will not earn their rightful place in the landscape by being of use. A positive attitude in general promotes positive experience of the effects of wind turbines. It is therefore essential to establish a sense of cooperation between the project management and the public. An open dialogue and continuous information will increase the possibilities for acceptance of future development. We must establish new codes of practice in permit processing because policies today contains idealogical and practical contradictions between the development and preservation of landscapes. (author)

Carlson, James H.

1992-01-01

There are three major components which are normally highlighted when the Civilian Radioactive Waste Management Program is discussed - the repository, the monitored retrievable storage facility, and the transportation system. These are clearly the major physical system elements and they receive the greatest external attention. However, there will not be a successful, operative waste management system without fully operational waste acceptance plans and logistics arrangements. This paper will discuss the importance of developing, on a parallel basis to the normally considered waste management system elements, the waste acceptance and logistics arrangements to enable the timely transfer of spent nuclear fuel from more than one hundred and twenty waste generators to the Federal government. The paper will also describe the specific activities the Program has underway to make the necessary arrangements. (author)

This work studies the in vitro degradation of Mg alloys for bioabsorbable implant applications under near physiological conditions. For this purpose, the degradation behaviour of Mg alloys in Dulbecco's modified eagle medium (DMEM) which is a commonly used cell culture medium is analysed. Unfortunately, DMEM can be contaminated by microorganisms, acidifying the medium and accelerating the Mg degradation process by dissolution of protective degradation layers, such as (Mg{sub x},Ca{sub y})(PO{sub 4}){sub z}. In this paper the influence of sterilization by applying UV-C radiation and antibiotics (penicillin/streptomycin) is analysed with two implant material candidates: Mg–Gd and Mg–Ag alloys; and pure magnesium as well as Mg–4Y–3RE as a reference. - Highlights: • Contamination of DMEM by microorganisms increases the degradation rate of Mg. • Mg and its alloys show passivation during long term immersion tests in DMEM. • The use of a control sample position is essential to assess H{sub 2} evolution in DMEM.

Wilson, E Vance; Lankton, Nancy K

2004-01-01

Health care providers are beginning to deliver a range of Internet-based services to patients; however, it is not clear which of these e-health services patients need or desire. The authors propose that patients' acceptance of provider-delivered e-health can be modeled in advance of application development by measuring the effects of several key antecedents to e-health use and applying models of acceptance developed in the information technology (IT) field. This study tested three theoretical models of IT acceptance among patients who had recently registered for access to provider-delivered e-health. An online questionnaire administered items measuring perceptual constructs from the IT acceptance models (intrinsic motivation, perceived ease of use, perceived usefulness/extrinsic motivation, and behavioral intention to use e-health) and five hypothesized antecedents (satisfaction with medical care, health care knowledge, Internet dependence, information-seeking preference, and health care need). Responses were collected and stored in a central database. All tested IT acceptance models performed well in predicting patients' behavioral intention to use e-health. Antecedent factors of satisfaction with provider, information-seeking preference, and Internet dependence uniquely predicted constructs in the models. Information technology acceptance models provide a means to understand which aspects of e-health are valued by patients and how this may affect future use. In addition, antecedents to the models can be used to predict e-health acceptance in advance of system development.

The elderly prison population is increasing and there is a significant amount of unidentified psychiatric morbidity among elderly prisoners. A sizeable number of elderly subjects are referred to regional forensic units. These units are able to provide advice but are reluctant to admit frail, physically ill and vulnerable elderly into their unit because the ward environment is considered inappropriate for them. A sizeable number of inpatients in medium and high secure units are elderly. This paper is an exploratory audit of referrals from a medium and high secure forensic psychiatry unit to a specialist consultation-only liaison old age psychiatry service, which was specifically developed to service the forensic unit. The demographic and clinical characteristics of the patients seen by this specialist service were similar to elderly inpatients in medium and high secure units. All referrals were judged to be appropriate and new management advice was provided in all cases. Main reasons for referral included diagnostic advice, placement advice and treatment advice. Establishing a diagnosis of dementia was considered important because Alzheimer's disease and Lewy body dementia can be treated with cholinesterase inhibitors. Placement advice was the most difficult to provide because of paucity of residential and nursing homes able and willing to accept patients with a forensic history. There is a need for a comprehensive model of specialist forensic old age psychiatry service at a regional or supraregional level. A consensus needs to be reached on the exact configuration of such a service.

The paper deals with the risk associated with the application of contrast medium in CT. The risk is to be seen in intolerance reactions, such as allergic or circulatory reactions and neurotoxic side-effects. In this paper the problems of renal failure caused by the injection of contrast medium are given special attention. Furthermore an iodine-induced hyperthyreosis might result. Especially the possible disturbance of the kidney function means that contrast medium should not be applied arbitrarily and that the examination should be done only by experienced staff. Furthermore the indication for the application of contrast medium in CT should be strictly qualified. (orig.) [de

2006-10-01

The Idaho Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) Disposal Facility (ICDF) has been designed to accept CERCLA waste generated within the Idaho National Laboratory. Hazardous, mixed, low-level, and Toxic Substance Control Act waste will be accepted for disposal at the ICDF. The purpose of this document is to provide criteria for the quantities of radioactive and/or hazardous constituents allowable in waste streams designated for disposal at ICDF. This ICDF Complex Waste Acceptance Criteria is divided into four section: (1) ICDF Complex; (2) Landfill; (3) Evaporation Pond: and (4) Staging, Storage, Sizing, and Treatment Facility (SSSTF). The ICDF Complex section contains the compliance details, which are the same for all areas of the ICDF. Corresponding sections contain details specific to the landfill, evaporation pond, and the SSSTF. This document specifies chemical and radiological constituent acceptance criteria for waste that will be disposed of at ICDF. Compliance with the requirements of this document ensures protection of human health and the environment, including the Snake River Plain Aquifer. Waste placed in the ICDF landfill and evaporation pond must not cause groundwater in the Snake River Plain Aquifer to exceed maximum contaminant levels, a hazard index of 1, or 10-4 cumulative risk levels. The defined waste acceptance criteria concentrations are compared to the design inventory concentrations. The purpose of this comparison is to show that there is an acceptable uncertainty margin based on the actual constituent concentrations anticipated for disposal at the ICDF. Implementation of this Waste Acceptance Criteria document will ensure compliance with the Final Report of Decision for the Idaho Nuclear Technology and Engineering Center, Operable Unit 3-13. For waste to be received, it must meet the waste acceptance criteria for the specific disposal/treatment unit (on-Site or off-Site) for which it is destined.

The Quiet Rise of Medium-Scale Farms in Malawi

Directory of Open Access Journals (Sweden)

Ward Anseeuw

2016-06-01

Full Text Available Medium-scale farms have become a major force in Malawi’s agricultural sector. Malawi’s most recent official agricultural survey indicates that these account for over a quarter of all land under cultivation in Malawi. This study explores the causes and multifaceted consequences of the rising importance of medium-scale farms in Malawi. We identify the characteristics and pathways of entry into farming based on surveys of 300 medium-scale farmers undertaken in 2014 in the districts of Mchinji, Kasungu and Lilongwe. The area of land acquired by medium-scale farmers in these three districts is found to have almost doubled between 2000 and 2015. Just over half of the medium-scale farmers represent cases of successful expansion out of small-scale farming status; the other significant proportion of medium-scale farmers are found to be urban-based professionals, entrepreneurs and/or civil servants who acquired land, some very recently, and started farming in mid-life. We also find that a significant portion of the land acquired by medium-scale farmers was utilized by others prior to acquisition, that most of the acquired land was under customary tenure, and that the current owners were often successful in transferring the ownership structure of the acquired land to a long-term leaseholding with a title deed. The study finds that, instead of just strong endogenous growth of small-scale famers as a route for the emergence of medium-scale farms, significant farm consolidation is occurring through land acquisitions, often by urban-based people. The effects of farmland acquisitions by domestic investors on the country’s primary development goals, such as food security, poverty reduction and employment, are not yet clear, though some trends appear to be emerging. We consider future research questions that may more fully shed light on the implications of policies that would continue to promote land acquisitions by medium-scale farms.

ANALYSIS OF ROMANIAN SMALL AND MEDIUM ENTERPRISES BANKRUPTCY RISK

Full Text Available Considering the fundamental role of small and medium enterprises in Romanian economy, this paper aims to quantify the level of their bankruptcy risk for 2009 and 2012 period, after debuting of financial crisis. The main reason of selecting this type of companies is that they represent the backbone of national economy. They have an indispensable role, because they offer jobs for great part of population and their contribution for GDP stimulation is considerable. In this paper it was applied two default risk models, namely the well known Altman’s Z-score model, based on five financial ratios and a bankruptcy predictor model developed by Teti et. al (2012 used firstly exclusively for Italian small and medium-sized enterprise for 2006-2009 period. The model proposed by Teti et. is based on the investigation of financially distressed and financially non-distressed Italian small and medium-sized enterprises during the financial crisis by using a discriminant analysis model. They conclude that there are four financial ratios, which characterized well the small and medium-sized enterprises bankruptcy risk. These variables are financial ratios, like: Debt/Total Assets, Return on Sales (ROS, EBIT/Interest Expenses and Working capital/EBIDTA. They consider that small and medium-sized enterprises require a particular approach in terms of bankruptcy risk analysis. In present study I try to compare the efficiency of traditional bankruptcy risk model with a small and medium-sized specific model. The necessary database for present analysis is ensured by simplified financial reports of 120 small and medium-sized enterprises registered in Bihor County. The selected enterprises are operating in manufacturing industry (21,67% and trading (78,33%. Present investigation has an important value in actual economic background, where the healthiness and sustainability of small and medium-sized enterprises is a great issue. The results of study shows contradictory

Australian wine consumers’ acceptance of and attitudes toward the use of additives in wine and food production

Full Text Available Yaelle Saltman, Trent E Johnson, Kerry L Wilkinson, Susan EP Bastian Department of Wine and Food, School of Agriculture, Food and Wine, The University of Adelaide, Waite Campus, Adelaide, SA, Australia. Abstract: Additives are routinely used in food and wine production to enhance product quality and/or prevent spoilage. Compared with other industries, the wine industry is only permitted to use a limited number of additives. Whereas flavor additives are often used to intensify the aroma and flavor of foods and beverages, the addition of flavorings to wine contravenes the legal definition of wine. Given the current legislation, it is perhaps not surprising that the potential use of food additives in wine production has not been explored. This study therefore investigated Australian wine consumers' acceptance of and attitudes toward the use of additives in food and wine production. Consumers (n=1,031 were segmented based on their self-reported wine knowledge (ie, subjective knowledge. Using these ratings, low (n=271, medium (n=528, and high (n=232 knowledge segments were identified. Consumers considered natural flavorings and colors, and additives associated with health benefits (eg, vitamins, minerals, and omega 3 fatty acids, to be acceptable food additives, irrespective of their level of wine knowledge. In contrast, the use of winemaking additives, even commonly used and legally permitted additives such as tartaric acid, preservatives, oak chips, and tannins, were considered far less acceptable, particularly, by less knowledgeable consumers. Surprisingly, natural flavorings were considered more acceptable than currently used winemaking additives. Consumers were therefore asked to identify the flavors they would most prefer in white and red wines. Fruit flavors featured prominently in consumer responses, eg, lemon and apple for white wines and blackcurrant and raspberry for red wines, but vanilla and/or chocolate, ie, attributes typically

Understanding Retailers’ Acceptance of Virtual Stores

Directory of Open Access Journals (Sweden)

Irene Y.L. Chen

2010-09-01

Full Text Available The acceptance of e-commerce among consumers has stimulated the rise of virtual stores. Increasing traditional retailers or people who do not have sufficient capital for maintaining a brick-and-mortar store have considered using virtual stores to reach global market. In the e-commerce literature, there has been rich research evidence concerning consumers’ acceptance of virtual stores. However, rigorous academic research on retailers’ acceptance of virtual stores is relatively scarce today. This study draws upon the theory of planned behavior and information richness theory to propose an integrated theoretical model. A field survey is used to collect data from e-tailers. The data are analyzed to examine the six relationships posited in the research model. Findings of this study provide a further research avenue for e-commerce, and implications for those who are managing or considering using virtual stores.

Working Toward Public Acceptance in Germany

1992-01-01

West German utilities show a typical three level structure: local distributors, regional producers/distributors and some ten nationwide producers/distributors. Only the latter have the necessary financial and organizational means for running nuclear power stations. Public acceptance, on the other hand, does not care for state borders. Today, the leading German electronic media and the relevant print media are being distributed and received nationwide, transporting opinion as well as acceptance or non-acceptance. This paper describes the main projects of 'Nuclear Information Group' and the strategy considerations behind. Information centers at NPP sites can cover local information needs, regional utilities will cope with regional needs. It became obvious at the very beginning of the nuclear controversy, however, that it is also necessary to establish an additional, strictly federal, i. e. central, organisation that takes care of all nationwide information needs

Full Text Available Tension headaches and migraines are the most common types of headaches that severely decline the daily functioning of patients. It seems that drug therapy is not useful by itself for most of these patients. The aim of this study was to evaluate the effect of acceptance and commitment therapy on the acceptance of pain and psychological inflexibility among women with chronic headache. It was a quasi experimental study using pretest- posttest with control group. The study population included women aged 20 to 40 who were suffering from chronic headaches and referred to a pain clinic in Tehran. In the study, 30 patients were selected and randomly divided into experimental and control groups (each group 15 members. Acceptance and Commitment therapy was implemented for eight one and a hours half sessions, once a week. Data collection tool in this study consisted of the questionnaire of pain acceptance and psychological flexibility. The results of this study showed that there was a significant difference in the variables of pain acceptance and psychological inflexibility between the experimental and control groups after the intervention .The results emphasized on the importance of this intervention in psychosomatic diseases to provide new horizons to clinical interventions.

Full Text Available There is increasing evidence that the microcirculation plays an important role in the pathogenesis of cardiovascular diseases. Changes in retinal vascular caliber reflect early microvascular disease and predict incident cardiovascular events. We performed a genome-wide association study to identify genetic variants associated with retinal vascular caliber. We analyzed data from four population-based discovery cohorts with 15,358 unrelated Caucasian individuals, who are members of the Cohort for Heart and Aging Research in Genomic Epidemiology (CHARGE consortium, and replicated findings in four independent Caucasian cohorts (n  =  6,652. All participants had retinal photography and retinal arteriolar and venular caliber measured from computer software. In the discovery cohorts, 179 single nucleotide polymorphisms (SNP spread across five loci were significantly associated (p<5.0×10(-8 with retinal venular caliber, but none showed association with arteriolar caliber. Collectively, these five loci explain 1.0%-3.2% of the variation in retinal venular caliber. Four out of these five loci were confirmed in independent replication samples. In the combined analyses, the top SNPs at each locus were: rs2287921 (19q13; p  =  1.61×10(-25, within the RASIP1 locus, rs225717 (6q24; p = 1.25×10(-16, adjacent to the VTA1 and NMBR loci, rs10774625 (12q24; p  =  2.15×10(-13, in the region of ATXN2,SH2B3 and PTPN11 loci, and rs17421627 (5q14; p = 7.32×10(-16, adjacent to the MEF2C locus. In two independent samples, locus 12q24 was also associated with coronary heart disease and hypertension. Our population-based genome-wide association study demonstrates four novel loci associated with retinal venular caliber, an endophenotype of the microcirculation associated with clinical cardiovascular disease. These data provide further insights into the contribution and biological mechanisms of microcirculatory changes that underlie cardiovascular

The Small and medium integral reactor is developed to be utilized for non-electric areas such as district heating and steam production for desalination and other industrial purposes, and then these applications may typically imply a closeness between the reactor and the user. It requires the reactor to be designed with the adoption of special functional and inherent safety features to ensure and promote a high level of safety and reliability, in comparison with the existing nuclear power plants. The objective of the present study is to establish the bases for the development of regulatory requirements and technical guides to address the special safety characteristics of the small and medium integral reactor. In addition, the study aims to identify and to propose resolutions to the possible safety concerns in the design of the small and medium integral reactor. 34 refs., 20 tabs. (author)

Kornides, Melanie L; McRee, Annie-Laurie; Gilkey, Melissa B

2018-03-01

Parental declination contributes to low human papillomavirus (HPV) vaccination coverage among US adolescents, resulting in missed opportunities for cancer prevention. We sought to characterize parents' acceptance of HPV vaccination after declination ("secondary acceptance"). In September 2016, we conducted an online survey with a national sample of parents of children ages 11 to 17 years. For those who reported having ever declined HPV vaccination for their children (n = 494), our survey assessed whether they accepted the vaccine at a subsequent visit. We used multivariable logistic regression to assess correlates of secondary acceptance. Overall, 45% of parents reported secondary acceptance of HPV vaccination, and an additional 24% intended to vaccinate in the next 12 months. In multivariable analyses, secondary acceptance was associated with receiving follow-up counseling about HPV vaccination from a health care provider (odds ratio, 2.16; 95% confidence interval, 1.42-3.28). However, only 53% of parents overall reported receiving such counseling. Secondary acceptance was also associated with receiving a higher quality HPV vaccine recommendation from a provider during the initial discussion and greater satisfaction with provider communication, as well as higher vaccination confidence. Among the reasons for secondary acceptance, parents most commonly reported the child getting older (45%), learning more about HPV vaccine (34%), and receiving a provider recommendation (33%). Our findings suggest secondary acceptance of HPV vaccination is common, with more than two-thirds of parents in this national sample accepting or intending to accept HPV vaccination after declination. Providers should seek to motivate secondary acceptance by delivering repeated, high-quality recommendations for HPV vaccination. Copyright © 2017 Academic Pediatric Association.

Torres-Moreno, Miriam; Tarrega, Amparo; Costell, Elvira; Blanch, Consol

2012-01-30

Chocolate properties can vary depending on cocoa origin, composition and manufacturing procedure, which affect consumer acceptability. The aim of this work was to study the effect of two cocoa origins (Ghana and Ecuador) and two processing conditions (roasting time and conching time) on dark chocolate acceptability. Overall acceptability and acceptability for different attributes (colour, flavour, odour and texture) were evaluated by 95 consumers. Differences in acceptability among dark chocolates were mainly related to differences in flavour acceptability. The use of a long roasting time lowered chocolate acceptability in Ghanaian samples while it had no effect on acceptability of Ecuadorian chocolates. This response was observed for most consumers (two subgroups with different frequency consumption of dark chocolate). However, for a third group of consumers identified as distinguishers, the most acceptable dark chocolate samples were those produced with specific combinations of roasting time and conching time for each of the cocoa geographical origin considered. To produce dark chocolates from a single origin it is important to know the target market preferences and to select the appropriate roasting and conching conditions.

The objective of this study was to determine if Chardonnay grape seed pomace (GSP), a waste stream of wine production, could be used as a functional ingredient in brewed coffee. Two consumer panels were conducted to assess the acceptance of coffee at coffee replacement (w/w) values of 0% (control), 6.25%, 12.50%, 18.75%, or 25% GSP. The 1st consumer panel (n = 80) assessed the coffee samples served "black." The 2nd panel (n = 67) assessed the coffee samples with adjustment (that is, sweeteners, milk, and cream) options available. Consumer sensory evaluation involved evaluating the 5 treatments individually for acceptance of appearance, aroma, taste/flavor, and overall acceptance using a 9-point hedonic scale. A check-all-that-apply questionnaire surveyed the sensory attributes describing aroma, appearance, and taste/flavor of the samples. Oxygen radical absorbance capacity was used to measure the effects of antioxidant levels in GSP coffee samples. Results showed that GSP could be added at 6.25% replacement without significantly affecting the overall consumer acceptance of coffee compared to the control (0% GSP). Above 6.25% GSP supplementation, the coffee beverage was described as more tan, milky, watery/dilute, and mild, and was generally less accepted by the consumers. GSP also increased the antioxidant capacity of the coffee compared to the control (0% GSP), with no significant differences among replacement values. Therefore, 6.25% GSP replacement is recommended for creating coffee beverages acceptable to consumers. Further in vivo investigation may substantiate the free-radical scavenging capacity of GSP coffee and its potential health benefits. © 2016 Institute of Food Technologists®.

We used genetic deletion of β2-microglobulin to study the influence of CD8(+) T cells on spinal cord demyelination, remyelination, axonal loss and brainstem N-acetyl aspartate levels during the acute and chronic phases of Theiler's murine encephalomyelitis virus (TMEV) infection. We used β2m(-/-) and β2m(+/+) B10.Q mice (of H-2(q) background) normally susceptible to TMEV-induced demyelination. Over the disease course, β2m(+/+) mice had increasing levels of demyelination and minimal late-onset remyelination. In contrast, β2m(-/-) mice had steady levels of demyelination from 45-390 dpi and remyelination was extensive and more complete. Early in the disease, brainstem NAA levels drop in both strains, but accordingly with remyelination and axonal preservation, NAA recover in β2m(-/-) mice despite equivalent brainstem pathology. At 270 dpi, β2m(+/+) mice had significantly fewer spinal cord axons than β2m(-/-) mice (up to 28% less). In addition, β2m(+/+) mice lost axons of all calibers, whereas β2m(-/-) mice had a modest loss of only medium- and large-caliber axons. This study further supports the hypothesis that CD8(+) T cells are involved in demyelination, and axonal loss following Theiler's virus-induced demyelination. © 2012 The Authors; Brain Pathology © 2012 International Society of Neuropathology.

Stoll, Laurie Cooper; Lilley, Terry Glenn; Pinter, Kelly

2017-01-01

The purpose of this article is to explore whether gender-blind sexism, as an extension of Bonilla-Silva's racialized social system theory, is an appropriate theoretical framework for understanding the creation and continued prevalence of rape myth acceptance. Specifically, we hypothesize that individuals who hold attitudes consistent with the frames of gender-blind sexism are more likely to accept common rape myths. Data for this article come from an online survey administered to the entire undergraduate student body at a large Midwestern institution (N = 1,401). Regression analysis showed strong support for the effects of gender-blind sexism on rape myth acceptance. © The Author(s) 2016.

Yao, Yongchang; Zhai, Zhichen; Wang, Yingjun

2014-01-01

The ATDC5 cell line is regarded as an excellent cell model for chondrogenesis. In most studies with ATDC5 cells, insulin medium (IM) was used to induce chondrogenesis while chondrogenic medium (CM), which was usually applied in chondrogenesis of mesenchymal stem cells (MSCs), was rarely used for ATDC5 cells. This study was mainly designed to investigate the effect of IM, CM, and growth medium (GM) on chondrogenesis of ATDC5 cells. ATDC5 cells were, respectively, cultured in IM, CM, and GM for a certain time. Then the proliferation and the chondrogenesis progress of cells in these groups were analyzed. Compared with CM and GM, IM promoted the proliferation of cells significantly. CM was effective for enhancement of cartilage specific markers, while IM induced the cells to express endochondral ossification related genes. Although GAG deposition per cell in CM group was significantly higher than that in IM and GM groups, the total GAG contents in IM group were the most. This study demonstrated that CM focused on induction of chondrogenic differentiation while IM was in favor of promoting proliferation and expression of endochondral ossification related genes. Combinational use of these two media would be more beneficial to bone/cartilage repair.

Cao, Chang-Qi; Cao, Hui; Qin, Ke-Cheng

1996-01-01

Spontaneous radiation in dissipative gas medium such as plasmas is investigated by Langevin equations and the modified Weisskopf-Wigner approximation. Since the refractive index of gas medium is expected to be nearly unity, we shall first neglect the medium polarization effect. We show that absorption in plasmas may in certain case modify the Einstein A coefficient significantly and cause a pit in the A coefficient-density curves for relatively low temperature plasmas and also a pit in the A coefficient-temperature curves. In the next, the effect of medium polarization is taken into account in addition. To our surprise, its effect in certain case is quite significant. The dispersive curves show different behaviors in different region of parameters.

We investigate theoretically the propagation of electromagnetic oscillating soliton in the form of breather in an anisotropic ferromagnetic medium. The interaction of magnetization with the magnetic field component of the electromagnetic (EM) wave has been studied by solving Maxwell's equations coupled with a Landau–Lifshitz equation for the magnetization of the medium. We made a small perturbation on the magnetization and magnetic field along the direction of propagation of EM wave in the framework of reductive perturbation method and the associated nonlinear magnetization dynamics is governed by a generalized derivative nonlinear Schrödinger (DNLS) equation. In order to understand the dynamics of the concerned system, we employ the Jacobi elliptic function method to solve the DNLS equation and deduce breatherlike soliton modes for the EM wave in the medium. - Highlights: • The propagation of electromagnetic oscillating soliton in an anisotropic ferromagnetic medium is investigated in the presence of varying external magnetic field. • The magnetization and electromagnetic wave modulates in the form of breathing like oscillating solitons. • The governing nonlinear spin dynamical equation is studied through a reductive perturbation method. • The magnetization components of the ferromagnetic medium are derived using Jacobi elliptic functions method with the aid of symbolic computation.

Medium Modifications of Hadron Properties and Partonic Processes

Energy Technology Data Exchange (ETDEWEB)

Brooks, W. K.; Strauch, S.; Tsushima, K.

2011-06-01

Chiral symmetry is one of the most fundamental symmetries in QCD. It is closely connected to hadron properties in the nuclear medium via the reduction of the quark condensate , manifesting the partial restoration of chiral symmetry. To better understand this important issue, a number of Jefferson Lab experiments over the past decade have focused on understanding properties of mesons and nucleons in the nuclear medium, often benefiting from the high polarization and luminosity of the CEBAF accelerator. In particular, a novel, accurate, polarization transfer measurement technique revealed for the first time a strong indication that the bound proton electromagnetic form factors in 4He may be modified compared to those in the vacuum. Second, the photoproduction of vector mesons on various nuclei has been measured via their decay to e+e- to study possible in-medium effects on the properties of the rho meson. In this experiment, no significant mass shift and some broadening consistent with expected collisional broadening for the rho meson has been observed, providing tight constraints on model calculations. Finally, processes involving in-medium parton propagation have been studied. The medium modifications of the quark fragmentation functions have been extracted with much higher statistical accuracy than previously possible.

This paper introduces an innovative statistical approach towards understanding how variation impacts the acceptance criteria of quality attributes. Because of more complex stage-wise acceptance criteria, traditional process capability measures are inadequate for general application in the pharmaceutical industry. The probability of acceptance concept provides a clear measure, derived from specific acceptance criteria for each quality attribute. In line with the 2011 FDA Guidance, this approach systematically evaluates data and scientifically establishes evidence that a process is capable of consistently delivering quality product. The probability of acceptance provides a direct and readily understandable indication of product risk. As with traditional capability indices, the acceptance probability approach assumes that underlying data distributions are normal. The computational solutions for dosage uniformity and dissolution acceptance criteria are readily applicable. For dosage uniformity, the expected AV range may be determined using the s lo and s hi values along with the worst case estimates of the mean. This approach permits a risk-based assessment of future batch performance of the critical quality attributes. The concept is also readily applicable to sterile/non sterile liquid dose products. Quality attributes such as deliverable volume and assay per spray have stage-wise acceptance that can be converted into an acceptance probability. Accepted statistical guidelines indicate processes with C pk > 1.33 as performing well within statistical control and those with C pk  1.33 is associated with a centered process that will statistically produce less than 63 defective units per million. This is equivalent to an acceptance probability of >99.99%.

Harz/Vesper: Acceptance Research with Logical Relations and Pragma-Dialectics

Science.gov (United States)

Harz, M.

2012-04-01

We use two different theories for our research on the acceptance of carbon capture and storage (CCS), geothermal energy and shale gas: logical relations and pragma-dialectics. With the theory of logical relations we can describe the structure of the terminus "acceptance" as a three-place or more relationship. We use the Newtonian binominal coefficients order to reflect on the complexity of the concept of acceptance. We are exploring relations between citizens, politicians, scientists, businesses and technologies. The technological-philosophical reflection on the topic "Determinants for acceptance of new technologies" concerns the issues of "Trust", "Security" as well as "Interest and Use" as the essential constituents of acceptance. Trust: Politicians, scientists and entrepreneurs need to understand themselves as advocates of acceptance. Acceptance is not automatic but requires a great effort and continuous personal commitment, as you want to secure acceptance not only for the short-term but for the long-term. The confidence curve follows a hysteresis loop as known from the magnetization of materials: It requires a significant effort. If the existing trust is lost due to erroneous communication or incorrect political action, the restoration effort is significantly greater. Citizens need to understand themselves as being asked for acceptance and as actively influencing the shapes of their life. They may not feel as victims or sufferers from technological developments but should have a realistic feeling of being able to influence - in fact - anything. "Openness creates openness." (H.-J. Bullinger) Security: The advocate promoting acceptance must take into account the security needs of the citizens with regard to the technologies which are supposed to be accepted. Even irrational fears are actual fears that can prevent acceptance. Interests and Goals of Usage: The advocate promoting acceptance must - sincerely and publicly - express his interest in the use and goals

[Acceptance and mindfulness-based cognitive-behavioral therapies].

Science.gov (United States)

Ngô, Thanh-Lan

2013-01-01

Cognitive behavioral therapy (CBT) is one of the main approaches in psychotherapy. It teaches the patient to examine the link between dysfunctional thoughts and maladaptive behaviors and to re- evaluate the cognitive biases involved in the maintenance of symptoms by using strategies such as guided discovery. CBT is constantly evolving in part to improve its' effectiveness and accessibility. Thus in the last decade, increasingly popular approaches based on mindfulness and acceptance have emerged. These therapies do not attempt to modify cognitions even when they are biased and dysfunctional but rather seek a change in the relationship between the individual and the symptoms. This article aims to present the historical context that has allowed the emergence of this trend, the points of convergence and divergence with traditional CBT as well as a brief presentation of the different therapies based on mindfulness meditation and acceptance. Hayes (2004) described three successive waves in behavior therapy, each characterized by "dominant assumptions, methods and goals": traditional behavior therapy, cognitive therapy and therapies based on mindfulness meditation and acceptance. The latter consider that human suffering occurs when the individual lives a restricted life in order avoid pain and immediate discomfort to the detriment of his global wellbeing. These therapies combine mindfulness, experiential, acceptance strategies with traditional behavior principles in order to attain lasting results. There are significant points of convergence between traditional CBT and therapies based on mindfulness meditation and acceptance. They are both empirically validated, based upon a theoretical model postulating that avoidance is key in the maintenance of psychopathology and they recommend an approach strategy in order to overcome the identified problem. They both use behavioral techniques in the context of a collaborative relationship in order to identify precise problems and to

Text recycling: acceptable or misconduct?

Science.gov (United States)

Harriman, Stephanie; Patel, Jigisha

2014-08-16

Text recycling, also referred to as self-plagiarism, is the reproduction of an author's own text from a previous publication in a new publication. Opinions on the acceptability of this practice vary, with some viewing it as acceptable and efficient, and others as misleading and unacceptable. In light of the lack of consensus, journal editors often have difficulty deciding how to act upon the discovery of text recycling. In response to these difficulties, we have created a set of guidelines for journal editors on how to deal with text recycling. In this editorial, we discuss some of the challenges of developing these guidelines, and how authors can avoid undisclosed text recycling.

This qualitative study explored the concept of acceptance of wholegrain foods in an adult population in the UK. Data was generated via focus groups with volunteers from a randomised controlled wholegrain based dietary intervention study (the WHOLEheart study). WHOLEheart volunteers, who did not habitually eat wholegrain foods, were randomised to one of three experimental regimes: (1) incorporating 60 g/day whole grains into the diet for 16 weeks; (2) incorporating 60 g/day whole grains into the diet for 8 weeks, doubling to 120 g/day for the following 8 weeks; (3) a control group. Focus groups to examine factors relating to whole grain acceptability were held one month post-intervention. For participants incorporating whole grains into their diet, acceptance was dependent upon: (a) 'trial acceptance', relating to the taste, preparation and perceived impact of the wholegrain foods on wellbeing, and (b) 'dietary acceptance' which involved the compatibility and substitutability of whole grains with existing ingredients and meal patterns. Barriers to sustained intake included family taste preferences, cooking skills, price and availability of wholegrain foods. Although LDL lowering benefits of eating whole grains provided the impetus for the WHOLEheart study, participants' self-reported benefits of eating wholegrain foods included perceived naturalness, high fibre content, superior taste, improved satiety and increased energy levels provided a stronger rationale for eating whole grains.

The features rendering orodispersible films (ODFs) patient-centric formulations are widely discussed in the scientific literature. However there is a lack of research studies exploring ODF characteristics with a potential impact on end-user acceptability. The aim of this study was to identify the key ODF characteristics affecting end-user acceptability by developing in vitro test methods for the prediction of ODFs acceptability and correlate these formulation characteristics with the data obtained from a human panel study. Four drug-free single-polymer films were prepared by solvent casting. Solutions of poly(vinyl) alcohol (PVOH) 39 KDa (P1), PVOH 197 KDa (P2), carboxymethylcellulose (CMC) 395 KDa (C1), and CMC 725 KDa (C2) were prepared. Texture analysis and Dynamic Mechanical Analysis (DMA) were used to assess film tack. Petri dish and drop methods were used to assess disintegration time. A human panel of 24 healthy young adults was employed to identify end-user acceptability criteria of the four study film samples. Texture analysis data of ODF tack were not found to be in agreement with the in vivo perceived stickiness in the mouth. However, measurement of the area under the adhesive force curve obtained by DMA correlated with in vivo perceived stickiness data for all samples. The disintegration times obtained by drop method were more comparable to human panel data than the petri dish method. Hence DMA and drop methods proved to be promising methodologies for the prediction of the end-user acceptability. The type and molecular weight of the film-forming polymer had a strong influence on stickiness perception, whereas only polymeric molecular weight influenced perceived disintegration time. The human panel study showed that Participant Reported Outcomes (PROs) for the perceived stickiness in the mouth and disintegration time of test films received significantly different scores between samples, and thus were identified as the key attributes with the

With the swift emergence of electronic medical information, the global popularity of mobile health (mHealth) services continues to increase steadily. This study aims to investigate the efficacy factors that directly or indirectly influence individuals' acceptance of mHealth services. Based on the technology acceptance model, this research incorporates efficacy factors into the acceptance decision process. A research model was proposed involving the direct and indirect effects of self-efficacy and response-efficacy on acceptance intention, along with their moderating effects. The model and hypotheses were validated using data collected from a field survey of 650 potential service users. The results reveal that: (1) self-efficacy and response-efficacy are both positively associated with perceived ease of use; and (2) self-efficacy and response-efficacy moderate the impact of perceived usefulness toward adoption intention. Self-efficacy and response-efficacy both play an important role in individuals' acceptance of mHealth services, which not only affect their perceived ease of use of mHealth services, but also positively moderate the effects of perceived usefulness on adoption intention. Our findings serve to provide recommendations that are specifically customized for mHealth service providers and their marketers.

Acceptable risks: occupational health in the nuclear industry

International Nuclear Information System (INIS)

Brown, M.S.

1980-01-01

This thesis examines the risk of working in the nuclear power industry. It reviews the history of the industry, government regulatory activities, and current scientific evidence of the health effects of radiation exposure. A discussion of current controversies over reduction in exposure limits is presented along with an analysis of the issues and problems associated with determinations of acceptable workplace risks. The thesis analyzes the controversy in terms of the acceptability of risk. The question of acceptability does not lend itself to technical evaluations of risks, costs, and benefits but is a social judgment of the necessity of a particular occupation or industry in society. At issue is the level of profits foregone by reductions in risk. This document concludes that the legitimacy of decisions about acceptable risks rests on the informed participation of all interested parties, including workers, in a process of defining socially necessary production. There must be opportunities to refuse higher risk jobs without losing a livelihood and adequate compensation for workers who accept hazardous jobs for the benefit of society

To evaluate the acceptability of different intra-oral and extra-oral orthodontic appliances, to rank orthodontic appliances from the most to the least attractive and to investigate the factors that may affect the acceptance of orthodontic treatment. A random sample of 800 students (schoolchildren and university students) were invited to participate in this study and a total of 688 students were included (86%). A self-administrated structured questionnaire was constructed for the purpose of this study. More than one-half in each age group (53%) claimed that they would accept to have orthodontic treatment. Acceptance of the different orthodontic appliances was affected by gender, age and type of school. Removable appliance was reported as the most acceptable and facemask was reported as the least acceptable orthodontic appliances. Majority of subjects ranked ceramic and facemask appliances as the most and the least attractive orthodontic appliances, respectively. The predictor variables for the acceptance of orthodontic treatment were perceived demand for orthodontic treatment, perceived positive effect of orthodontic treatment and expected benefits from orthodontic treatment. Removable appliance was the most acceptable orthodontic appliance whereas ceramic appliance was ranked as the most attractive one. Facemask was the least acceptable and the least attractive option.

Optical activity is investigated in a chiral medium by employing the four level cascade atomic model, in which the optical responses of the atomic medium are studied with Kerr nonlinearity. Light entering into a chiral medium splits into circular birefringent beams. The angle of divergence between the circular birefringent beams and the polarization states of the two light beams is manipulated with Kerr nonlinearity. In the stationary chiral medium the angle of divergence between the circular birefringent beams is calculated to be 1.3 radian. Furthermore, circular birefringence is optically controlled in a spinning chiral medium, where the maximum rotary photon drag angle for left (right) circularly polarized beam is ±1.1 (±1.5) microradian. The change in the angle of divergence between circular birefringent beams by rotary photon drag is calculated to be 0.4 microradian. The numerical results may help to understand image designing, image coding, discovery of photonic crystals and optical sensing technology. - Highlights: • Coherent control of a circular birefringence in a chiral medium is studied. • Angle of divergence between birefringent beams is modified with Kerr nonlinearity. • Rotary photon drag is controlled for birefringent beams and enhanced with Kerr nonlinearity in a spinning medium. • Rotation of the angle of divergence is observed with mechanical rotation of the medium about an axis and modified with Kerr effect. • A change in the angle of divergence is calculated by about a microradian with rotary photon drag.

The Impact of Rendered Protein Meal Oxidation Level on Shelf-Life, Sensory Characteristics, and Acceptability in Extruded Pet Food.

2016-07-28

Pet foods are expected to have a shelf-life for 12 months or more. Sensory analysis can be used to determine changes in products and to estimate products' shelf-life. The objectives of this study were to (1) investigate how increasing levels of oxidation in rendered protein meals used to produce extruded pet food affected the sensory properties and (2) determine the effect of shelf-life on pet owners' acceptability of extruded pet food diet formulated without the use of preservative. Pet food diets contained beef meat bone meal (BMBM) and chicken byproduct meal (CBPM) in which the oxidation was retarded with ethoxyquin, mixed tocopherols, or none at all, and then extruded into dry pet foods. These samples represented low, medium, and high oxidation levels, respectively. Samples were stored for 0, 3, 6, 9, and 12 months at ambient temperature. Each time point, samples were evaluated by six highly trained descriptive panelists for sensory attributes related to oxidation. Samples without preservatives were chosen for the acceptability test, since the differences in sensory characteristics over storage time were more distinguishable in those samples. Pet owners evaluated samples for aroma, appearance and overall liking. Descriptive sensory analysis detected significant changes in oxidized-related sensory characteristics over storage time. However, the differences for CBPM samples were more pronounced and directional. The consumer study showed no differences in pet owners' acceptability for BMBM samples. However, the noticeable increase in aroma characteristics (rancid aroma 0.33-4.21) in CBPM samples over storage time did have a negative effect on consumer's liking (overall liking 5.52-4.95).

Predicting the acceptance of advanced rider assistance systems.

Science.gov (United States)

Huth, Véronique; Gelau, Christhard

2013-01-01

The strong prevalence of human error as a crash causation factor in motorcycle accidents calls for countermeasures that help tackling this issue. Advanced rider assistance systems pursue this goal, providing the riders with support and thus contributing to the prevention of crashes. However, the systems can only enhance riding safety if the riders use them. For this reason, acceptance is a decisive aspect to be considered in the development process of such systems. In order to be able to improve behavioural acceptance, the factors that influence the intention to use the system need to be identified. This paper examines the particularities of motorcycle riding and the characteristics of this user group that should be considered when predicting the acceptance of advanced rider assistance systems. Founded on theories predicting behavioural intention, the acceptance of technologies and the acceptance of driver support systems, a model on the acceptance of advanced rider assistance systems is proposed, including the perceived safety when riding without support, the interface design and the social norm as determinants of the usage intention. Since actual usage cannot be measured in the development stage of the systems, the willingness to have the system installed on the own motorcycle and the willingness to pay for the system are analyzed, constituting relevant conditions that allow for actual usage at a later stage. Its validation with the results from user tests on four advanced rider assistance systems allows confirming the social norm and the interface design as powerful predictors of the acceptance of ARAS, while the extent of perceived safety when riding without support did not have any predictive value in the present study.

Full Text Available The mixed results of information technology (IT investment have made the investigation of user acceptance of IT increasingly challenging. A growing body of research in user acceptance of IT literature has limited focus on individual professionals as target users. Therefore, this research investigates how external variables, namely individual differences and system characteristics influence lecturers as individual professionals to accept the internet technology. Technology Acceptance Model (TAM and Theory of Planned Behavior (TPB are used as the main reference in this research. Findings of this research indicate that individual differences (computer self-efficacy, knowledge of search domain and system characteristics (terminology, screen design, relevance have indirect impact through perceived ease of use, perceived usefulness, and attitude on lecturers’ intention to use the internet. Specifically, computer self-efficacy and screen design have direct and indirect impact on intention. One issue concerning with the explanatory power of the proposed research model, which is based on TAM and TPB, compared to the rival model, which is called extended TAM, is also analyzed.

Heat transfer in porous medium can be derived from the fundamental laws of flow in porous region ass given by Henry Darcy. The fluid flow and energy transport inside the porous medium can be described with the help of momentum and energy equations. The heat transfer in cylindrical porous medium differs from its counterpart in radial and axial coordinates. The present work is focused to discuss the finite element formulation of heat transfer in cylindrical porous medium. The basic partial differential equations are derived using Darcy law which is the converted into a set of algebraic equations with the help of finite element method. The resulting equations are solved by matrix method for two solution variables involved in the coupled equations.

Effect of acidity of a medium on the spectroscopic characteristics of riboflavin aqueous solutions is investigated by the method of fluorescent and absorption spectroscopy. Significant deformation of the electronic spectra of riboflavin aqueous solutions irradiated with unfiltered light of a PRK-2 lamp is observed. It is established that riboflavin photostability in an acid medium is about twice as much as the photostability in a neutral medium, which is caused by the formation of a protonated species.

Bekier, Marek; Molesworth, Brett R C

2017-06-01

Air navigation service providers worldwide see increased use of automation as one solution to overcome the capacity constraints imbedded in the present air traffic management (ATM) system. However, increased use of automation within any system is dependent on user acceptance. The present research sought to determine if the point at which an individual is no longer willing to accept or cooperate with automation can be manipulated. Forty participants underwent training on a computer-based air traffic control programme, followed by two ATM exercises (order counterbalanced), one with and one without the aid of automation. Results revealed after exposure to a task with automation assistance, user acceptance of high(er) levels of automation ('tipping point') decreased; suggesting it is indeed possible to alter automation acceptance. Practitioner Summary: This paper investigates whether the point at which a user of automation rejects automation (i.e. 'tipping point') is constant or can be manipulated. The results revealed after exposure to a task with automation assistance, user acceptance of high(er) levels of automation decreased; suggesting it is possible to alter automation acceptance.

Coherent neutrino interactions in a dense medium

Motivated by the effect of matter on neutrino oscillations (the MSW effect) we study in more detail the propagation of neutrinos in a dense medium. The dispersion relation for massive neutrinos in a medium is known to have a minimum at nonzero momentum p∼G F ρ/√(2). We study in detail the origin and consequences of this dispersion relation for both Dirac and Majorana neutrinos both in a toy model with only neutral currents and a single neutrino flavor and in a realistic open-quotes standard modelclose quotes with two neutrino flavors. We find that for a range of neutrino momenta near the minimum of the dispersion relation, Dirac neutrinos are trapped by their coherent interactions with the medium. This effect does not lead to the trapping of Majorana neutrinos. copyright 1997 The American Physical Society

Conclusion: Academic misconducts were mainly considered more acceptable than professional misconducts. Our results show that perceptions of acceptable conducts amongst optometry students are not very different from other students, and, against our initial prediction, do not show a general change in misconduct perception when students become more mature. Universities should pay more attention to this problem and take action.

performance in first assessments. 94% of the students participating in tutorials offered in the study year 2013/14 rated the tutorials as "excellent" or "good". An objective benefit has been shown by a significant increase in re-assessment scores with an effect size between the medium and large magnitudes for participants of tutorials compared to non-participants in the years 2012, 2013 and 2014. In addition, significantly higher pass rates of re-assessments could be observed. Acceptance, utilisation and benefit of the assessed peer teaching programme are high. Beyond the support of students, a contribution to the individualisation of studies and teaching is made. Further studies are necessary to investigate possible influences of large-scale peer teaching programmes, for example on the reduction of study length and drop-off rates, as well as additional effects on academic achievements.

2015-01-01

Dose calculation in high dose rate brachytherapy with 192 Ir is usually based on the TG-43U1 protocol where all media are considered to be water. Several dose calculation algorithms have been developed that are capable of handling heterogeneities with two possibilities to report dose: dose-to-medium-in-medium (D m,m ) and dose-to-water-in-medium (D w,m ). The relation between D m,m and D w,m for 192 Ir is the main goal of this study, in particular the dependence of D w,m on the dose calculation approach using either large cavity theory (LCT) or small cavity theory (SCT). A head and neck case was selected due to the presence of media with a large range of atomic numbers relevant to tissues and mass densities such as air, soft tissues and bone interfaces. This case was simulated using a Monte Carlo (MC) code to score: D m,m, D w,m (LCT), mean photon energy and photon fluence. D w,m (SCT) was derived from MC simulations using the ratio between the unrestricted collisional stopping power of the actual medium and water. Differences between D m,m and D w,m (SCT or LCT) can be negligible (<1%) for some tissues e.g. muscle and significant for other tissues with differences of up to 14% for bone. Using SCT or LCT approaches leads to differences between D w,m (SCT) and D w,m (LCT) up to 29% for bone and 36% for teeth. The mean photon energy distribution ranges from 222 keV up to 356 keV. However, results obtained using mean photon energies are not equivalent to the ones obtained using the full, local photon spectrum. This work concludes that it is essential that brachytherapy studies clearly report the dose quantity. It further shows that while differences between D m,m and D w,m (SCT) mainly depend on tissue type, differences between D m,m and D w,m (LCT) are, in addition, significantly dependent on the local photon energy fluence spectrum which varies with distance to implanted sources.

The promise of acceptance as an NGO security management approach.

Science.gov (United States)

Fast, Larissa; Freeman, Faith; O'Neill, Michael; Rowley, Elizabeth

2015-04-01

This paper explores three questions related to acceptance as a security management approach. Acceptance draws upon relationships with community members, authorities, belligerents and other stakeholders to provide consent for the presence and activities of a non-governmental organisation (NGO), thereby reducing threats from these actors. Little is documented about how NGOs gain and maintain acceptance, how they assess and monitor the presence and degree of acceptance, or how they determine whether acceptance is effective in a particular context. Based on field research conducted in April 2011 in Kenya, South Sudan and Uganda, we address each of these three issues and argue that acceptance must be actively sought as both a programme and a security management strategy. In the paper we delineate elements common to all three contexts as well as missed opportunities, which identify areas that NGOs can and should address as part of an acceptance approach. © 2015 The Author(s).

FFTBM and primary pressure acceptance criterion

International Nuclear Information System (INIS)

Prosek, A.

2004-01-01

When thermalhydraulic computer codes are used for simulation in the area of nuclear engineering the question is how to conduct an objective comparison between the code calculation and measured data. To answer this the fast Fourier transform based method (FFTBM) was developed. When the FFTBM method was developed the acceptance criteria for primary pressure and total accuracy were set. In the recent study the FFTBM method was used for accuracy quantification of RD-14M large LOCA test B9401 calculations. The blind accuracy analysis indicated good total accuracy while the primary pressure criterion was not fulfilled. The objective of the study was therefore to investigate the reasons for not fulfilling the primary pressure acceptance criterion and the applicability of the criterion to experimental facilities simulating heavy water reactor. The results of the open quantitative analysis showed that sensitivity analysis for influence parameters provide sufficient information to judge in which calculation the accuracy of primary pressure is acceptable.

Temirkhanova, Z U; Gashimova, P Sh; Safonova, N V; Moroz, A F; Khazenson, L V

1999-01-01

Campylobacter agar, nutrient medium intended for the isolation of bacteria of the genus Campylobacter from clinical material, has been developed. The composition of the medium includes sprat hydrolysate, aerotolerant additive (ferric sulfate--oxide, sodium pyruvate, sodium pyrosulfite), sodium glutaminate, agar. The selective properties of the medium are ensured by introducing the mixture of antibiotics consisting of polymyxin B, rifampicin, amphotericin B, ristomycin. The balanced composition of Campylobacter agar ensures the aerotolerance of Campylobacter organisms and gives the optimal conditions for their growth when the inoculated material is cultivated in the atmosphere made up of the mixture of three gases (5% of oxygen, 10% of carbon dioxide, 85% of nitrogen), as well as under the conditions of a "candle vessel". The medium suppresses the development of the associative microflora diluted 10(-1). As shown in the trial of the quality of Campylobacter agar by the inoculation of material taken from patients with acute enteric infections, agricultural animals and monkeys, the medium has pronounced selective, properties with regard to extraneous microflora, while ensuring the isolation of Campylobacter on the level of the control medium.

Treatments for irritable bowel syndrome: patients' attitudes and acceptability

Roberts Lesley

2008-12-01

Full Text Available Abstract Background Irritable Bowel Syndrome, a highly prevalent chronic disorder, places significant burden on the health service and the individual. Symptomatic distress and reduced quality of life are compounded by few efficacious treatments available. As researchers continue to demonstrate the clinical efficacy of alternative therapies, it would be useful to gain a patient-perspective of treatment acceptability and identify patient's attitudes towards those modalities considered not acceptable. Methods Six hundred and forty-five participants identified from an earlier IBS-prevalence study received a postal questionnaire to evaluate preferences and acceptability of nine forms of treatment. Proportions accepting each form of treatment were calculated and thematic analysis of qualitative data undertaken. Results A total of 256 (39.7% of 645 potential respondents completed the questionnaire (mean age 55.9 years, 73% female. Tablets were most acceptable (84%, followed by lifestyle changes (diet (82%, yoga (77%. Acupuncture (59% and suppositories (57% were less acceptable. When explaining lack of acceptability, patient views fell into four broad categories: dislike treatment modality, do not perceive benefit, general barriers and insufficient knowledge. Scepticism, lack of scientific rationale and fear of CAM were mentioned, although others expressed a dislike of conventional medical treatments. Past experiences, age and health concerns, and need for proof of efficacy were reported. Conclusion Most patients were willing to accept various forms of treatment. However, the reservations expressed by this patient-population must be recognised with particular focus directed towards allaying fears and misconceptions, seeking further evidence base for certain therapies and incorporating physician support and advice.

Lensless ghost imaging through the strongly scattering medium

2016-01-01

Lensless ghost imaging has attracted much interest in recent years due to its profound physics and potential applications. In this paper we report studies of the robust properties of the lensless ghost imaging system with a pseudo-thermal light source in a strongly scattering medium. The effects of the positions of the strong medium on the ghost imaging are investigated. In the lensless ghost imaging system, a pseudo-thermal light is split into two correlated beams by a beam splitter. One beam goes to a charge-coupled detector camera, labeled as CCD2. The other beam goes to an object and then is collected in another charge-coupled detector camera, labeled as CCD1, which serves as a bucket detector. When the strong medium, a pane of ground glass disk, is placed between the object and CCD1, the bucket detector, the quality of ghost imaging is barely affected and a good image could still be obtained. The quality of the ghost imaging can also be maintained, even when the ground glass is rotating, which is the strongest scattering medium so far. However, when the strongly scattering medium is present in the optical path from the light source to CCD2 or the object, the lensless ghost imaging system hardly retrieves the image of the object. A theoretical analysis in terms of the second-order correlation function is also provided. (paper)

Real group velocity in a medium with dissipation

International Nuclear Information System (INIS)

Muschietti, L.; Dum, C.T.

1993-01-01

When a medium is dissipative, the classic expression for the group velocity, dω/dk, is complex with an imaginary part often being far from negligible. To clarify the role of this imaginary term, the motion of a wave packet in a dissipative, homogeneous medium is examined. The integral representation of the packet is analyzed by means of a saddle-point method. It is shown that in a moving frame attached to its maximum the packet looks self-similar. A Gaussian packet keeps its Gaussian identity, as is familiar for the case of a nondissipative medium. However, the central wave number of the packet slowly changes because of a differential damping among the Fourier components: Im(dω/dk)=dγ/dk≠0, where ω≡ω r +iγ. The packet height can be computed self-consistently as integrated damping (or growth). The real group velocity becomes a time-dependent combination of Re(dω/dk) and Im(dω/dk). Only where the medium is both homogeneous and loss free, does the group velocity remain constant. Simple ''ray-tracing equations'' are derived to follow the packet centers in coordinate and Fourier spaces. The analysis is illustrated with a comparison to geometric optics, and by two applications: the case of a medium with some resonant damping (or growth) and the propagation of whistler waves in a collisional plasma

Medium-range dielectric order in systems with collectivized electrons

International Nuclear Information System (INIS)

Ismagilov, A.M.; Kopaev, Yu.V.

1993-01-01

The problem of formation of a medium-range dielectric order (on a scale much larger than the interatomic one) due to electron-electron correlations and to scattering by an impurity in a system near a phase transition into a long-range order state is solved by a microscopic approach. It is shown that for a weak impurity potential the effect of medium-range order formation is stronger than the effect of long-range order suppression related to scattering by an impurity. The influence of medium-range order on the one-particle excitation spectrum and on the density of states is considered. It is found that since the medium-range order in a system is due to correlations of electron and hole states open-quotes coupledclose quotes by a continuous set of inhomogeneity vectors (in contrast to the long-range order formed on a discrete set of such vectors), the density of states varies on an energy scale determined by the mean absolute value of these vectors. Therefore in a system undergoing phase transition into an inhomogeneous state with the modulus q 0 of inhomogeneity vectors the medium-range order forms in the density of states a pseudogap of scale length v F q 0 (v F is the Fermi velocity). This distinguishes such a system substantially from one, which tends to a phase transition into a homogeneous state (q 0 ≡0), where the medium-range order forms a pseudogap of scale length v F /ξ much-lt v F q 0 (ξ is the correlation length). The possible role of medium dielectric order effects in high-T c superconductors is discussed. 30 refs., 6 figs

An approach for determining the acceptable levels of nuclear risk

International Nuclear Information System (INIS)

1978-03-01

The objective of this study was to develop a methodology for determining the acceptable levels of risk with respect to nuclear energy. It was concluded that the Atomic Energy Control Board should identify the interest groups that affect its choice of an acceptable level of risk, determine their expectations, and balance the expectations of the various groups such that the resulting acceptable level of risk is still acceptable to the Board. This would be done by interviewing experts on the subject of nuclear safety, developing and pretesting a public questionnaire, and surveying the public on acceptable cost-risk combinations

The effect of country of origin (local, Switzerland, Argentina, Uruguay), finishing diet (grass, grass plus concentrate, concentrate), and price (low, medium, high) on consumer's beef choice and segmentation was evaluated in Spain, France and United Kingdom. Sensory acceptability of Uruguayan beef from different production systems was also evaluated and contrasted with consumers' beef choices. Origin was the most important characteristic for the choice of beef with preference for meat produced locally. The second most important factor was animal feed followed by price with preference for beef from grass-fed animals and lowest price. The least preferred product was beef from Uruguay, concentrate-fed animals and highest price. Sensory data showed higher acceptability scores for Uruguayan beef from grass-fed animals with or without concentrate supplementation than animals fed concentrate only. Consumer segments with distinct preferences were identified. Foreign country promotion seems to be fundamental for marketing beef in Europe, as well as the development of different marketing strategies to satisfy each consumer segment.

The recent enactment of a law that allows infant euthanasia in Belgium raises questions with varied answers. To contribute to a better understanding of the topic, euthanasia and legislation concepts are described. After a bioethical analysis, we propose as conclusion that children euthanasia could only be acceptable in very exceptional situations in which palliative measures have failed. The answer should be that it is not acceptable in our setting, not until we have public policies, protocols and palliative care services for terminally ill children.

Anti-optic-null medium: Achieving the optic-null medium effect by enclosing an air region with relatively low-anisotropy media

Science.gov (United States)

Sun, Fei; Liu, Yichao; He, Sailing

2016-07-01

A so-called anti-optic-null medium (anti-ONM), which can be utilized to cancel the optic-null medium (ONM) and create many novel optical illusions, is introduced and designed by transformation optics (TO). Optical separation illusions can be achieved with an anti-ONM. With the help of the anti-ONM, we can achieve the same optical illusions where ONM is required via a shelled structure filled with low anisotropic medium, which is easier to realize for some novel optical devices designed by TO and optical surface transformation. The special function of the anti-ONM will lead to a new way to design optical devices or simplify the material requirements. Overlapping illusions, and wave-front reshapers are designed to demonstrate the function of the proposed method.

The national growth mediums were developed for isolating and cultivating of main agents of purulent bacterial meningitis--haemophilus agar, chocolate agar, PBM-agar. The growing and selective characteristics of developed growth mediums are examined. The haemophilus agar ensures growth of Haemophilus influenzae. The chocolate agar, PBM-agar ensure growth of Neisseria meningitidis, Streptococcus pneumoniae and Haemophilus influenzae. By growing characteristics, the national growth mediums match foreign analogues. Under application of growth mediums with selective additions it is possible to achieve selective isolation of main agents of purulent bacterial meningitis with inhibition of growth of microbes-associates.

Acceptance sampling using judgmental and randomly selected samples

Energy Technology Data Exchange (ETDEWEB)

Sego, Landon H.; Shulman, Stanley A.; Anderson, Kevin K.; Wilson, John E.; Pulsipher, Brent A.; Sieber, W. Karl

2010-09-01

We present a Bayesian model for acceptance sampling where the population consists of two groups, each with different levels of risk of containing unacceptable items. Expert opinion, or judgment, may be required to distinguish between the high and low-risk groups. Hence, high-risk items are likely to be identifed (and sampled) using expert judgment, while the remaining low-risk items are sampled randomly. We focus on the situation where all observed samples must be acceptable. Consequently, the objective of the statistical inference is to quantify the probability that a large percentage of the unsampled items in the population are also acceptable. We demonstrate that traditional (frequentist) acceptance sampling and simpler Bayesian formulations of the problem are essentially special cases of the proposed model. We explore the properties of the model in detail, and discuss the conditions necessary to ensure that required samples sizes are non-decreasing function of the population size. The method is applicable to a variety of acceptance sampling problems, and, in particular, to environmental sampling where the objective is to demonstrate the safety of reoccupying a remediated facility that has been contaminated with a lethal agent.

2017-12-01

Photons, as quanta of electromagnetic fields, determine the electromagnetic properties of an extremely hot and dense medium. Considering the properties of the photons in the interacting medium of charged particles, we explicitly calculate the electromagnetic properties such as the electric permittivity, magnetic permeability, refractive index and the propagation speed of electromagnetic signals in an extremely hot and dense background. Photons acquire a dynamically generated mass in such a medium. The screening mass of the photon, the Debye shielding length and the plasma frequency are calculated as functions of the statistical parameters of the medium. We study the properties of the propagating particles in astrophysical systems of distinct statistical conditions. The modifications in the properties of the medium lead to the equation of state of the system. We mainly calculate all these parameters for extremely high temperatures of the early universe.

2017-07-01

Full Text Available Involvement and development of the private sector in boosting the economy nationwide is a main objective of the current program of the government, which means that a good cooperation between small and medium companies, private companies and multinationals and public environment including both public institutions and policies implemented and developed by them, becomes more than necessary. The paper summarizes the findings of a quantitative research based on a self-applied questionnaire which was aimed at Romanian small and medium-sized enterprises and also of a qualitative research that gives an overview of the process of elaborating and implementing a public policy. The involvement of small and medium-sized enterprises in the process of designing and implementing a public policy can become indispensable but it is well know that there is, in fact, a lack of initiative at this level, from both parties. One of the main research questions of this paper is to find out how much do representatives of small and medium-sized enterprises get involved in the process of elaborating a public policy and how much do these actions and measures impact the organizational policies of the companies themselves. A good cooperation between the business environment and the public institutions and a strong correlation of their joint efforts, should become a common practice between both parties, being crucial that this form of cooperation to be initiated from the very beginning. The contribution of this paper is a practical one, given the fact that the paper itself entails the direct responses of small and medium-sized enterprises on the current and future public policies that directly targets them, providing as well an analysis on the effects of public policies on small and medium-sized enterprises. Thus being said, the paper can also be a guide for both small and medium-sized enterprises in providing examples and measures of involvement and favorable public policies

Issues affecting the acceptance of hydrogen fuel

International Nuclear Information System (INIS)

Schulte, I.; Hart, D.; Vorst, R. van der

2004-01-01

While the topic of hydrogen as an alternative vehicle fuel is gaining increasing attention internationally, one significant aspect of its introduction has been given less attention than others: the public acceptance of such a new technology and fuel. After reviewing the existing literature on acceptance, risk perception and customer satisfaction, this paper describes the development of a model that illustrates important aspects in influencing a person's attitude towards a new product. 'Values', 'wants' and 'perception' are the three components found to influence acceptance, they themselves are affected by 'social background' and 'experience'. Suggestions are then given on how to use marketing methods, education projects and product exposure in order to maximise the likelihood of a successful introduction of hydrogen as an alternative fuel.

Smalley, J.L.

1995-01-01

The purpose of this Acceptance Test Procedure is to provide instruction and documentation for acceptance testing of the rotary mode core sample trucks, HO-68K-4600 and HO-68K-4647. The rotary mode core sample trucks were based upon the design of the second core sample truck (HO-68K-4345) which was constructed to implement rotary mode sampling of the waste tanks at Hanford. Acceptance testing of the rotary mode core sample trucks will verify that the design requirements have been met. All testing will be non-radioactive and stand-in materials shall be used to simulate waste tank conditions. Compressed air will be substituted for nitrogen during the majority of testing, with nitrogen being used only for flow characterization

1988-01-01

Non-ionic contrast medium, iopromide (Ultravist), was compared with ionic contrast medium, ioxitalamate (Telebrix), for efficacy and safety in 63 patients undergoing left ventriculography. In all patients, adverse symptoms and signs including pain, heat sense, nausea, vomiting, etc., were checked during and shortly after the injection. Blood pressure, heart rate, EKG and left ventricular pressure were also monitored during the study, and CBC, UA, BUN and creatinine were checked before and 24 hours after the study. The cineangiographic films were analysed and compared by 2 radiologists for the quality. Serious adverse effect did not occur in any case. Minor effects, especially nausea, were lee frequently caused by non-ionic contrast medium than by ionic contrast medium, and heat sense to non-ionic contrast medium was less severe than to ionic contrast medium. Except slightly elevated LVEDP at 1,5 minutes after the study in patients given ionic contrast medium, there was no significant change of electrophysiologic parameters and laboratory findings in both groups. In regard to image quality, there was no significant difference between ionic and non-ionic contrast medium. Thus non-ionic contrast medium, iopromide, appears to be safer for use in left ventriculography than the conventional ionic contrast medium, particularly in those patients at high risk of adverse effects.

2015-01-01

Objective To study patients’ acceptance of corticotomy-assisted orthodontics as a treatment option. Methods Adult patients seeking orthodontic treatment were asked to complete two sets of questionnaires; the first set included questions about age, sex, and level of education and general questions about orthodontic treatment; and the second set was related to the corticotomy-assisted orthodontics. Before answering the corticotomy questions, a brief description of the clinical procedure was explained and photographs of an actual procedure were shown. Results A total of 150 subjects were approached and 129 (86%) agreed to answer the questionnaires (72 male and 57 female patients). Of these, only 3.1% did hear about corticotomy and 7.8% selected corticotomy instead of extraction. Fear from the surgery (53.2%) was the most frequent reason for not selecting corticotomy followed by fear from pain (36.9%). The acceptance of corticotomy between males and females was similar. No relationship was found between the level of education and prior knowledge of the procedure, P=0.857. Prior knowledge about corticotomy was not a factor in selecting it as a treatment option (P=0.556) to reduce the treatment time (P=0.427). Conclusion The acceptance of corticotomy-assisted orthodontics as a treatment option was low. Fear from the surgery was the main reason for not selecting it. The acceptance of corticotomy-assisted orthodontics was not related to patient’s level of education or sex. PMID:26316719

Shoulder dystocia--malpractice or acceptable risk?

Science.gov (United States)

Skolbekken, J A

2000-09-01

In 1988 a new patient insurance system was introduced in Norway. It was initially described as an 'objectified' system, similar to one based on the no-fault principle. Early doubts were raised about the system's status, as it contains rules stating that compensation will not be given if the medical intervention is adequate and the involved risk is acceptable. This study was undertaken to examine the practice of these rules. An archival study was performed on the 41 shoulder dystocia cases that had been closed in the decade from 1988-1997. These cases were selected as shoulder dystocia was found to be the obstetrical event most often leading to a decision on acceptable risk. The most common injury in these cases was Erb's palsy, but fatalities and brain injuries were also observed. Compensation was given in nine cases, whereas it was denied due to an acceptable medical risk in the remaining cases. Indications of inconsistency among the reached decisions were found, and judged to be a result of differences of opinion between expert witnesses on the adequacy of the obstetrical practice. Doubts are raised as to whether similar decisions are reached in similar cases. Shoulder dystocia may be an acceptable risk in the sense that it is hard to predict and prevent. Whether the consequences of such a risk should be compensated, remains a political and economical issue. Present thinking leads to decisions that create a divide between the lucky unlucky and the plainly unlucky.

RX emission of thin astrophysical plasma: interstellar medium and intra-cluster medium

International Nuclear Information System (INIS)

Arnaud, Monique

1984-01-01

As previous publications presented an important discrepancy of ionisation rates in astrophysical plasmas, this research thesis first reports a systematic study (by isoelectric sequence) of ionisation cross sections, based on measurements performed by mono-energetic beams, and on quantum assessments. The author proposes simple analytic fits for ionisation rates, for direct ionisation and for excitation-self-ionisation of ions of interest in astrophysics. He reports a critical review of recombination rates published in the literature, and the calculation of radiative recombination rates for different ions (hydrogen-like, helium-like, and lithium-like). Software have then been developed to determine the ionisation rate at the equilibrium and out of it for thin plasma, and to obtain ion fraction tables for different ions (H, He, C, N, O, Ne, Na, Mg, Al, Si, S, Ar, Ca, Fe, Ni). Then, a software integrating recent data on collisional excitation rates has been used to calculate the emission spectrum of a thin plasma with respect to temperature. These results are then used for the study of the interstellar medium and of supernovae remnants, and finally for the study of the intra-cluster medium [fr

Organic chemistry and biology of the interstellar medium

Sagan, C.

1973-01-01

Interstellar organic chemistry is discussed as the field of study emerging from the discovery of microwave lines of formaldehyde and of hydrogen cyanide in the interstellar medium. The reliability of molecular identifications and comparisons of interstellar and cometary compounds are considered, along with the degradational origin of simple organics. It is pointed out that the contribution of interstellar organic chemistry to problems in biology is not substantive but analogical. The interstellar medium reveals the operation of chemical processes which, on earth and perhaps on vast numbers of planets throughout the universe, led to the origin of life, but the actual molecules of the interstellar medium are unlikely to play any significant biological role.

Sensory analysis of pet foods has been emerging as an important field of study for the pet food industry over the last few decades. Few studies have been conducted on understanding the pet owners’ perception of pet foods. The objective of this study is to gain a deeper understanding on the perception of the visual characteristics of dry dog foods by dog owners in different consumer segments. A total of 120 consumers evaluated the appearance of 30 dry dog food samples with varying visual characteristics. The consumers rated the acceptance of the samples and associated each one with a list of positive and negative beliefs. Cluster Analysis, ANOVA and Correspondence Analysis were used to analyze the consumer responses. The acceptability of the appearance of dry dog foods was affected by the number of different kibbles present, color(s), shape(s), and size(s) of the kibbles in the product. Three consumer clusters were identified. Consumers rated highest single-kibble samples of medium sizes, traditional shapes, and brown colors. Participants disliked extra-small or extra-large kibble sizes, shapes with high-dimensional contrast, and kibbles of light brown color. These findings can help dry dog food manufacturers to meet consumers’ needs with increasing benefits to the pet food and commodity industries.

Grammaticality, Acceptability, and Probability: A Probabilistic View of Linguistic Knowledge.

Science.gov (United States)

Lau, Jey Han; Clark, Alexander; Lappin, Shalom

2017-07-01

The question of whether humans represent grammatical knowledge as a binary condition on membership in a set of well-formed sentences, or as a probabilistic property has been the subject of debate among linguists, psychologists, and cognitive scientists for many decades. Acceptability judgments present a serious problem for both classical binary and probabilistic theories of grammaticality. These judgements are gradient in nature, and so cannot be directly accommodated in a binary formal grammar. However, it is also not possible to simply reduce acceptability to probability. The acceptability of a sentence is not the same as the likelihood of its occurrence, which is, in part, determined by factors like sentence length and lexical frequency. In this paper, we present the results of a set of large-scale experiments using crowd-sourced acceptability judgments that demonstrate gradience to be a pervasive feature in acceptability judgments. We then show how one can predict acceptability judgments on the basis of probability by augmenting probabilistic language models with an acceptability measure. This is a function that normalizes probability values to eliminate the confounding factors of length and lexical frequency. We describe a sequence of modeling experiments with unsupervised language models drawn from state-of-the-art machine learning methods in natural language processing. Several of these models achieve very encouraging levels of accuracy in the acceptability prediction task, as measured by the correlation between the acceptability measure scores and mean human acceptability values. We consider the relevance of these results to the debate on the nature of grammatical competence, and we argue that they support the view that linguistic knowledge can be intrinsically probabilistic.

Technical considerations associated with spent fuel acceptance. Final report

International Nuclear Information System (INIS)

Supko, E.M.

1996-06-01

This study was initiated by the Electric Power Research Institute (EPRI) to identify technical considerations associated with spent fuel acceptance and implementation of a waste management system that includes the use of transportable storage systems, and to serve as an opening dialogue among Standard Contract Holders and the department of Energy's Office of Civilian Radioactive Waste management (OCRWM) prior to the development of waste acceptance criteria or issuance of a Notice of Proposed Rulemaking by OCRWM to amend the Standard Contract. The original purpose of the Notice of Proposed Rulemaking was to address changes to the Standard Contract to implement a multi-purpose canister based system and to address other issues that were not adequately addressed in the standard contract. Even if DOE does not develop a multi-purpose canister based system for waste acceptance, it will still be necessary to develop waste acceptance criteria in order to accept spent fuel in transportable storage systems that are being deployed for at-reactor storage. In this study, technical issues associated with spent fuel acceptance will be defined and potential options and alternatives for resolution of technical considerations will be explored

How much oil will the world consume in 2012? What role will OPEC play in global oil production? Will biofuels become an important part of the oil market? How will the refinery sector cope? The International Energy Agency (IEA) Medium-Term Oil Market Report tackles these questions, adopting a perspective that goes beyond the traditional short-term market analysis provided in the IEA Oil Market Report. Drawing on current futures curves and the investment threshold for upstream projects, the Medium-Term Oil Market Report analyses how global demand and supply balances may develop. By assessing all firmly planned upstream and downstream projects worldwide, this report forecasts supply and demand potential for crude and petroleum products over the next five years. The results provide an invaluable insight into vital issues such as surplus production capacity and product supply. An essential report for all policymakers, market analysts, energy experts and anyone interested in understanding and following oil market trends, the Medium-Term Oil Market Report is a further element of the strong commitment of the IEA to improving and expanding the quality, timeliness and accuracy of energy data and analysis.

Acceptance of sugar reduction in flavored yogurt.

Chollet, M; Gille, D; Schmid, A; Walther, B; Piccinali, P

2013-09-01

To investigate what level of sugar reduction is accepted in flavored yogurt, we conducted a hedonic test focusing on the degree of liking of the products and on optimal sweetness and aroma levels. For both flavorings (strawberry and coffee), consumers preferred yogurt containing 10% added sugar. However, yogurt containing 7% added sugar was also acceptable. On the just-about-right scale, yogurt containing 10% sugar was more often described as too sweet compared with yogurt containing 7% sugar. On the other hand, the sweetness and aroma intensity for yogurt containing 5% sugar was judged as too low. A second test was conducted to determine the effect of flavoring concentration on the acceptance of yogurt containing 7% sugar. Yogurts containing the highest concentrations of flavoring (11% strawberry, 0.75% coffee) were less appreciated. Additionally, the largest percentage of consumers perceived these yogurts as "not sweet enough." These results indicate that consumers would accept flavored yogurts with 7% added sugar instead of 10%, but 5% sugar would be too low. Additionally, an increase in flavor concentration is undesirable for yogurt containing 7% added sugar. Copyright © 2013 American Dairy Science Association. Published by Elsevier Inc.

Full Text Available This paper explores the issues that influence the diffusion of innovation as it relates to the adoption of e-commerce by Small and Medium Enterprises (SMEs. It seeks to identify factors facilitating and inhibiting such adoption across contexts – regional, small city and large city. This analysis is cross cultural so the impact of differing economic and cultural issues also will be identified in this research. Whilst it is generally accepted that the strategic use of information technology (IT is vital in the marketplace, the rate of such uptake between small and large businesses varies. This research seeks to identify the reasons for this variation. It is critical to understand such factors so that steps can be taken to redress inequity of uptake that might be identified. The paper endeavours to explore factors that are needed to facilitate and encourage IT adoption and so positively influence user acceptance and use of IT innovations in SMEs. Reasons for such uptake as well as strategic approach to the adoption of e-commerce, and variations regarding same also will be considered. The paper examines existing theory as it pertains to the diffusion of innovation acknowledging the perspective of regional and urban SMEs in various cultural contexts. Empirical investigation exploring this diffusion, the rate of and approach to the uptake by SMEs is planned using a case study methodology

Stem cell-derived conditioned medium has a promising prospect to be produced as pharmaceuticals for regenerative medicine. To investigate various methods to obtain stem cell-derived conditioned medium (CM) to get an insight into their prospect of application in various diseases. Systematic review using keywords "stem cell" and "conditioned medium" or "secretome" and "therapy." Data concerning treated conditions/diseases, type of cell that was cultured, medium and supplements to culture the cells, culture condition, CM processing, growth factors and other secretions that were analyzed, method of application, and outcome were noted, grouped, tabulated, and analyzed. Most of CM using studies showed good results. However, the various CM, even when they were derived from the same kind of cells, were produced by different condition, that is, from different passage, culture medium, and culture condition. The growth factor yields of the various types of cells were available in some studies, and the cell number that was needed to produce CM for one application could be computed. Various stem cell-derived conditioned media were tested on various diseases and mostly showed good results. However, standardized methods of production and validations of their use need to be conducted.

The review under consideration reports on the acceptance and citizen participation in renewable energies. First of all, the authors define the term acceptance and describe the process of how this term is developed. Subsequently, the authors use the results of a representative survey by TNS Infratest (Munich, Federal Republic of Germany) in order to describe the peculiarity of the technology-specific acceptance of renewable energies in Germany. The facility-related acceptance of renewable energies is described in conjunction with the question whether there is a so-called NIMBY (Not in my backyard effect). Acceptable solutions for the problems of acceptance are presented based on two best practice examples by means of different procedures of the citizen's participation.

Giancarlo Tisi

2013-09-01

Full Text Available PURPOSE: The aim of this study was to evaluate the comprehension and acceptance of HPV vaccination in parents of adolescent boys aged 11 to 15 years. METHODS: A cross-sectional survey was conducted by means of questionnaires sent directly to the homes of all families with young males aged between 11 and 15, residents of three municipalities of the Province of Brescia, Italy. The documentation also contained an informative leaflet summarizing the HPV-related disease characteristics, the burden of disease and the available strategies for prevention and treatment, illustrating the rationale of vaccination and describing the project and its phases. The questionnaire included questions on demographic data, acceptance and motivations for HPV vaccination. The collected data was analyzed using descriptive statistics. At the end of the study, parents who received the questionnaires were also offered the possibility of vaccinating their male sons for free. RESULTS: From a total of 1072 questionnaires sent, 161 where returned from the three selected municipalities (average response rate 15%; 97% of adolescent males involved in the study were Italian and 91% Catholic; 97% of parents declared themselves to be willing to vaccinate their sons: the principal motivation given (92% was prevention of the disease, cancerous or not, related to viral infection. Among the respondents not willing to vaccinate their sons, the motivation was lack of information about the vaccine and the disease. At the end of the study, around 71 boys were vaccinated. DISCUSSION: To our knowledge, this is the first survey in Italy exclusively conducted on parents of adolescent males about the acceptability and feasibility of vaccination against HPV: a very high percentage of respondents was favorable to accept the vaccination for their sons, the main motivation being the fact that parents considered protecting their sons from HPV-related diseases highly important. Of the 161 boys

Recent studies of the gas and dust between the stars, the interstellar medium, reveal a complex chemistry which indicates that prebiotic organic chemistry is ubiquitous. The relationship between this interstellar chemistry and the organic chemistry of the early solar system and the Earth is explored. The interstellar medium is also considered as likely to have a continuing influence upon the climate of the Earth and other planets. Life forms as known are not only descendants of the organic evolution begun in the interstellar medium, but their continuing evolution is also molded through occasional interactions between the interstellar medium, the Sun and the climate on Earth.

Does green consumerism increase the acceptance of wind power?

International Nuclear Information System (INIS)

Thøgersen, John; Noblet, Caroline

2012-01-01

In this paper, we discuss what might be termed an action-based learning approach to promoting important pro-environmental actions, such as support for or acceptance of environmental policy. Such an approach involves promoting simple and easy behaviours as entry points for more radical steps towards sustainability, referred to as “catalytic” or “wedge” behaviours. Despite the obvious need for innovative approaches to promote important pro-environmental behaviour, and sound theoretical backing for such concepts, there is a lack of research testing the key propositions of this approach. In a survey study based on a random sample of residents of the state of Maine, USA, we find that both everyday “green” behaviour and the acceptance of an expansion of wind power are rooted in environmental concern and that everyday “green” behaviour gives a significant contribution to predicting acceptance of wind power when controlling for environmental concern. Hence, the promotion of everyday “green” behaviours may prepare the grounds for increasing acceptance of more far-reaching changes in the population, such as an expansion of wind power. - Highlights: ► Acceptance of wind power increases with environmental concern. ► So does everyday “green” consumerism. ► Green consumerism further increases acceptance of wind power. ► The effect of environmental concern on acceptance is partly mediated through green consumerism. ► Participants in the study are a random sample of residents of Maine, USA.

Full Text Available We study nuclear stopping in central collisions for heavy-ion induced reactions in the Fermi energy domain (15-100 AMeV. Using the large dataset provided by the 4π array INDRA, we determine that stopping can be directly related to the transport properties in the nuclear medium. By looking specifically at protons, we present a comprehensive body of experimental results concerning the mean free path, the nucleon-nucleon cross-section and in-medium effects in nuclear matter.

Measuring medium-induced gluons via jet grooming

Tywoniuk, Konrad; Mehtar-Tani, Yacine

2017-11-01

Jet substructure observables and applications of jet grooming techniques in heavy-ion collisions are still in its infancy and provide new alleys for studying medium modifications of perturbative degrees of freedom. We note that these measurements, given the right transverse momentum range, can be uniquely sensitive to rare medium-induced emissions inside of the jet cone. This corresponds to an infrared enhancement that would, for instance, affect the distribution of the groomed momentum-sharing variable zg measured using the SoftDrop procedure.

Development of Carrot Medium Suitable for Conidia Production of Venturia nashicola

Directory of Open Access Journals (Sweden)

Eu Ddeum Choi

2017-02-01

Full Text Available The causal fungus of pear scab, Venturia nashicola, grows slowly and rarely produces conidia on artificial media in the laboratory, but it produced conidia on the Cheongah medium containing Cheongah powder. V. nashicola grew too slow to produce conidia until 15 days after cultivation but produced conidia with 4 × 10⁴ conidia/plate 30 days after cultivation on the Cheongah medium containing 1% Cheongah powder. V. nashicola showed a peak production of conidia with 4.5 × 10⁵ conidia/plate 60 days after cultivation on the carrot medium containing 2% carrot powder, one of the constituents of Cheongah powder. The carrot medium is considered to be the best medium to obtain conidia of V. nashicola in the laboratory until now. This is the first report on the development of a suitable medium for conidia production of V. nashicola, as far as we know.

Cotyledons from 7-day-old in vitro broccoli seedling were used as explant source in adventitious root induction on MS medium supplemented with 30 g/l sucrose, 1.6 mg/l IBA and 7 g/l agar. Adventitious roots from cotyledons were transferred to liquid medium containing the same components as rooting medium for two weeks, then subcultured to MS medium with diferent sugar, macrominerals and casein hydrolysate concentrations. The best adventitious root growth was observed in half-strength MS medium supplemented with 40 g/l sucrose, 600 mg/l casein hydrolysate and 1.6 mg/l IBA (growth index of 4.00 in about 14 culture days with inoculum density of 1.0 g fresh weight / 30 ml of culture medium). The culturing process can be stopped on the 28th day for root biomass and on the 35th day for glucosinolates.

2015-03-03

To describe the level of overdetection people would find acceptable in screening for breast, prostate, and bowel cancer and whether acceptability is influenced by the magnitude of the benefit from screening and the cancer specific harms from overdetection. Online survey. Women were presented with scenarios on breast and bowel cancer, men with scenarios on prostate and bowel cancer. For each particular cancer, we presented epidemiological information and described the treatment and its consequences. Secondly, we presented two different scenarios of benefit: one indicating a 10% reduction in cancer specific mortality and the second indicating a 50% reduction. Online survey of the population in the United Kingdom. Respondents were part of an existing panel of people who volunteer for online research and were invited by email or online marketing. We recruited 1000 respondents, representative for age and sex for the UK population. Number of cases of overdetection people were willing to accept, ranging from 0-1000 (complete screened population) for each cancer modality and each scenario of benefit. There was large variability between respondents in the level of overdetection they would find acceptable, with medians ranging from 113 to 313 cases of overdetection per 1000 people screened. Across all scenarios, 4-7% of respondents indicated they would accept no overdetection at all compared with 7-14% who thought that it would be acceptable for the entire screened population to be overdetected. Acceptability in screening for bowel cancer was significantly lower than for breast and prostate cancer. People aged 50 or over accepted significantly less overdetection, whereas people with higher education levels accepted more; 29% of respondents had heard of overdetection before. Acceptability of overdetection in cancer screening is variable. Invitations for screening should include clear information on the likelihood and consequences of overdetection to allow people to make an

Temperature distribution in a uniformly moving medium

International Nuclear Information System (INIS)

Mitchell, Joseph D; Petrov, Nikola P

2009-01-01

We apply several physical ideas to determine the steady temperature distribution in a medium moving with uniform velocity between two infinite parallel plates. We compute it in the coordinate frame moving with the medium by integration over the 'past' to account for the influence of an infinite set of instantaneous point sources of heat in past moments as seen by an observer moving with the medium. The boundary heat flux is simulated by appropriately distributed point heat sources on the inner side of an adiabatically insulating boundary. We make an extensive use of the Green functions with an emphasis on their physical meaning. The methodology used in this paper is of great pedagogical value as it offers an opportunity for students to see the connection between powerful mathematical techniques and their physical interpretation in an intuitively clear physical problem. We suggest several problems and a challenging project that can be easily incorporated in undergraduate or graduate courses

These days, most of the Malaysians realize that the consumption of debit card will help them to reduce the household debt. Thus, it is important to analyse the acceptance of debit cards for further enhancement and expanding its market share in Malaysia. In addition, there is lacked of research being conducted on the determinants affecting the acceptance of debit cards among Malaysians. Thus, the study aimed to investigate the factors affecting the acceptance of debit cards. This study focuses on payment methods, consumer attitude, and safety of debit card in acceptance of debit cards. Questionnaires were distributed to the 300 respondents. The sampling procedure adopted was stratified random sampling. The data obtained were analysed using SPSS 20.0 which involves scale reliability, descriptive and regression analysis. The result indicates that payment methods, consumer attitude and safety are the determinants of debit cards acceptance. Safety is the best predictor as most of the customers are confidents to use debit cards because of the security being developed around these debit card transactions. The analyses presented in this study can be used by policymakers and managers as a guide to promote banking products and services. The findings achieved in this study will be of interest for practitioners and academics concerned with developments of the Malaysian banking industry

The acceptable level of radiation risk for public members, that is 10 -5 /y, was proposed by ICRP and other international organizations. We studied to survey basic procedures of deriving this value and to derive an acceptable risk value in Japan by using similar procedures. The basic procedures to derive 10 -5 /y were found as follows; (1) 0.1 percent of annual mortality from all diseases, (2) 0.1 percent of life time risk, (3) one percent of mortality from all causes in each age cohort and (4) corresponding value to 1 mSv annual radiation exposure. From these bases we derived the value of 10 -5 /y as acceptable risk level in Japan. The perception to risk level of 10 -5 /y in conventional life was investigated by means of questionnaires for 1,095 college students living in Tokyo. The risks considered in this study were natural background radiation, coffee, skiing, X-ray diagnosis, spontaneous cancer, passive smoking and air pollution. The most acceptable risk was the risk related with natural background radiation. And the risk of natural background radiation was more easily accepted by the students who had knowledges on natural background radiation. On the other hand, the risk from air pollution or passive smoking was the most adverse one. (author)

When is physician assisted suicide or euthanasia acceptable?

Frileux, S; Lelièvre, C; Muñoz Sastre, M T; Mullet, E; Sorum, P C

2003-12-01

To discover what factors affect lay people's judgments of the acceptability of physician assisted suicide and euthanasia and how these factors interact. Participants rated the acceptability of either physician assisted suicide or euthanasia for 72 patient vignettes with a five factor design--that is, all combinations of patient's age (three levels); curability of illness (two levels); degree of suffering (two levels); patient's mental status (two levels), and extent of patient's requests for the procedure (three levels). Convenience sample of 66 young adults, 62 middle aged adults, and 66 older adults living in western France. In accordance with the functional theory of cognition of N H Anderson, main effects, and interactions among patient factors and participants' characteristics were investigated by means of both graphs and ANOVA. Patient requests were the most potent determinant of acceptability. Euthanasia was generally less acceptable than physician assisted suicide, but this difference disappeared when requests were repetitive. As their own age increased, participants placed more weight on patient age as a criterion of acceptability. People's judgments concur with legislation to require a repetition of patients' requests for a life ending act. Younger people, who frequently are decision makers for elderly relatives, place less emphasis on patient's age itself than do older people.

Considerations for acceptability in Bible translation

Directory of Open Access Journals (Sweden)

Diphus C. Chemorion

2009-09-01

Full Text Available The ministry of Bible translation is an important component of the Great Commission (Matthew 28:18�20 and its mandate is to reach everyone with the word of God. One of the main goals of a Bible translation project is to produce a translation that will be used by the church in a given language group. Bible translation teams believe that the lives of the intended recipients will be changed positively when they gain access to Scripture in their own language. However, recent developments regarding Scripture use have shown that the success of any Bible translation project depends on whether or not its products are acceptable. If a translation is not acceptable to the intended audience, it may not be used, and as a result, it may fail to bring about the desired impact. This article explores the concept of �acceptability� as used in Bible translation and highlights important considerations that translators need to keep in mind in order to enhance the acceptability of their translation products.

Effect of culture medium, host strain and oxygen transfer on recombinant Fab antibody fragment yield and leakage to medium in shaken E. coli cultures

Science.gov (United States)

2013-01-01

Background Fab antibody fragments in E. coli are usually directed to the oxidizing periplasmic space for correct folding. From periplasm Fab fragments may further leak into extracellular medium. Information on the cultivation parameters affecting this leakage is scarce, and the unpredictable nature of Fab leakage is problematic regarding consistent product recovery. To elucidate the effects of cultivation conditions, we investigated Fab expression and accumulation into either periplasm or medium in E. coli K-12 and E. coli BL21 when grown in different types of media and under different aeration conditions. Results Small-scale Fab expression demonstrated significant differences in yield and ratio of periplasmic to extracellular Fab between different culture media and host strains. Expression in a medium with fed-batch-like glucose feeding provided highest total and extracellular yields in both strains. Unexpectedly, cultivation in baffled shake flasks at 150 rpm shaking speed resulted in higher yield and accumulation of Fabs into culture medium as compared to cultivation at 250 rpm. In the fed-batch medium, extracellular fraction in E. coli K-12 increased from 2-17% of total Fab at 250 rpm up to 75% at 150 rpm. This was partly due to increased lysis, but also leakage from intact cells increased at the lower shaking speed. Total Fab yield in E. coli BL21 in glycerol-based autoinduction medium was 5 to 9-fold higher at the lower shaking speed, and the extracellular fraction increased from ≤ 10% to 20-90%. The effect of aeration on Fab localization was reproduced in multiwell plate by variation of culture volume. Conclusions Yield and leakage of Fab fragments are dependent on expression strain, culture medium, aeration rate, and the combination of these parameters. Maximum productivity in fed-batch-like conditions and in autoinduction medium is achieved under sufficiently oxygen-limited conditions, and lower aeration also promotes increased Fab accumulation into

Nowdays, due to the increasing importance of quality care, organizations focuse on the improving provision, management and distribution of health. On one hand, incremental costs of the new technologies and on the other hand, increased knowledge of health care recipients and their expectations for high quality services have doubled the need to make changes in order to respond to resource constraints (financial, human, material). For this purpose, several technologies, such as barcode, have been used in hospitals to improve services and staff productivity; but various factors effect on the adoption of new technologies and despite good implementation of a technology and its benefits, sometimes personnel don't accept and don't use it. This is an applied descriptive cross-sectional study in which all the barcode users in health information management department of the three academic hospitals (Feiz, Al-Zahra, Ayatollah Kashani) affiliated to Isfahan University of Medical Sciences were surveyed by the barcode technology acceptance questionnaire, in six areas as following: barcode ease of learning, capabilities, perception of its usefulness and its ease of use, users attitudes towards its using, and users intention. The finding showed that barcode technology total acceptance was relatively desirable (%76.9); the most compliance with TAM model was related to the user perceptions about the ease of use of barcode technology and the least compliance was related to the ease of learning barcode technology (respectively %83.7 and %71.5). Ease of learning and barcode capability effect of usefulness and perceived ease of barcode technology. Users perceptions effect their attitudes toward greater use of technology and their attitudes have an effect on their intention to use the technology and finally, their intention makes actual use of the technology (acceptance). Therefore, considering the six elements related to technology implementation can be important in the barcode

How Smog Awareness Influences Public Acceptance of Congestion Charge Policies

Directory of Open Access Journals (Sweden)

Lingyi Zhou

2017-09-01

Full Text Available Although various studies have investigated public acceptance of congestion charge policies, most of them have focused on behavioral and policy-related factors, and did not consider the moderating influence that individual concern about smog and perceived smog risk may have on public acceptance. This paper takes the congestion charge policy in China, targeted at smog and traffic control, and checks how smog awareness—including smog concerns and perceived smog risks, besides behavioral and policy-related factors—might influence public acceptance of the policy. In this paper, we found both a direct and moderating causal relationship between smog awareness and public acceptance. Based on a sample of 574 valid questionnaires in Beijing and Shanghai in 2016, an ordered logistic regression modeling approach was used to delineate the causality between smog awareness and public acceptance. We found that both smog concerns, such as perceived smog risk, and willingness to pay (WTP were both directly and indirectly positively correlated with public acceptance. These findings imply that policymakers should increase policy fairness with environmental-oriented policy design and should express potential policy effectiveness of the smog controlling policy to citizens to increase their acceptance level.
