Few decisions are more important to an electric utility company than the one to build a nuclear generating facility. This decision will require continuous management attention to the nuclear project for periods of up to ten years on the part of the utility. Effective management of such a large, complex project requires an owner's organization skilled in such areas as engineering, heavy construction, procurement, and project control. The paper describes a method for designing the owner's nuclear organization. Factors considered include the identification of milestone events and phases of the project and identification of key organizational groups and their degree of involvement. A series of important decision milestones is also identified for structuring the organization. A step-by-step analysis involving a set of evaluation criteria results in a recommended organization that can be staffed by the owner according to the degree of involvement desired. This technique of analysis could also be performed using different evaluation criteria resulting in other options for the owner's organization

The bond dogs develop with their owner received increased attention in the last years but no study aimed at characterizing the way in which owners interact with their dogs in their daily life and how this might influence dog behavior. In order to examine how dog owners interact with their dogs, we first analyzed the behavior of 220 dog owners in 8 different standardized situations involving the owner-dog dyad. We extracted 3 behavioral factors related to " Owner Warmth ," " Owner Social Support ," and " Owner Control ." Further, we investigated whether owner personality, gender and age are associated with these three factors. Results indicated that older owners scored lower in " Owner Warmth " and in " Owner Social Support " and higher in " Owner Control " than younger owners. Furthermore, owners scoring high in " Owner Control " scored lower in the personality trait Openness and owners scoring high in " Owner Social Support " scored lower in the personality trait Conscientiousness. Finally, we also analyzed whether the dogs' reaction to an unfamiliar woman's threatening approach was associated with the owners' interaction styles. Results showed that dogs that searched for proximity of their owners during the threatening situation had owners scoring higher in " Owner Warmth ," as compared to dogs that reacted more autonomously, approaching the unfamiliar experimenter. Analogies between dog-owner interaction styles and human parenting styles are discussed considering the implications of the present findings for human social psychology as well as the practical relevance for dog welfare and human safety.

Full Text Available Light-induced degradation (LID of p-type Cz solar cells has plagued the industry for many decades. However, in recent years, new techniques for solving this LID have been developed, with hydrogen passivation of the boron-oxygen defects appearing to be an important contributor to the solution. Advanced hydrogenation approaches involving the control of the charge state for the hydrogen atoms in silicon to enhance their diffusivity and reactivity are developed and evaluated in this work for commercial application using a prototype industrial tool in conjunction with solar cells manufactured on commercial production lines. This prototype tool, unlike the previous successful laser-based laboratory approaches, is based on the use of LEDs for controlling the charge state of the hydrogen atoms. The illumination from the LEDs is also used in this work to passivate process-induced defects and contamination from the respective production lines with significant improvements in both efficiency and stability. The results indicate that the low-cost LED-based industrial tool performs as well as the laser-based laboratory tool for implementing these advanced hydrogen passivation approaches.

During recent years, several studies have revealed that human-dog relationships are based on a well-established and complex bond. There is now evidence suggesting that the dog-human affectional bond can be characterized as an "attachment". The present study investigated possible association between the owners' attachment profile assessed throughout a new semi-projective test (the 9 Attachment Profile) and the owner-dog attachment bond evaluated using a modified version of those used in studyi...

Forest owners' timber sales satisfaction

Pammo, R.; Ripatti, P.

2003-01-01

The TTS Institute has carried out a study concerning forest owners' timber sales. The material was collected in 2002 via a mail inquiry that targeted forest owners who sold timber during the years 1997-1999 and 1999-2002. Three quarters of the forest owners sold timber to the same timber buying company during both periods of 1997-1999 and 1999-2002. The most important reasons for selling to the same buyer were that they purchased all timber assortments, reliability and good timber price. Mainly the same reasons also applied when changing the timber buying company. The most sensitive groups to changing timber buyer were 60-69 year old, entrepreneurs, men, and owners of forest holdings between 20-29 hectares, owners of inherited forests and joint forest ownerships. The forest owners assessed the timber buying company's operations and its staff on the basis of the last timber sale. The forest owners gave best values for the timber buyer's reliability, the purchase of all timber assortments and the timber buyers' reputation. The worst values were given for cross-cutting and response to complaints. No less than 95 percent of forest owners were prepared to recommend their timber trade partner to acquaintances, friends or other forest owners. Yet only half of the forest owners recognized that their last timber sale experience would not affect which company will be selected for the nest timber sale process

2017-03-01

Full Text Available Background The practice of feeding of diets containing raw animal products (RAP to pets (dogs and cats is discouraged by veterinary organizations and governmental public health organizations. Nevertheless, the practice of feeding RAP to pets is increasing in popularity. Pet owner motivations for feeding RAP diets to pets have not been explored and the benefits of RAP diets remain largely anecdotal. We hypothesized that pet owners feeding RAP diets would not rely on veterinary advice in choosing their pet’s diet. We also hypothesized that these owners would have lower levels of trust in veterinary advice with respect to nutrition relative to pet owners not feeding RAP. Methods An anonymous web-based survey was developed to identify pet owner motivations for feeding RAP diets, and to characterize the veterinarian-client relationships of individuals feeding RAP diets. Results There were 2,337 respondents and 2,171 completed surveys. Of survey respondents, 804 reported feeding RAP at the time of the survey. While 20% of pet owners feeding RAP relied on online resources to determine what or how much RAP to feed, only 9% reported consulting with a veterinarian in making decisions about feeding RAP. Pet owners feeding RAP reported lower levels of trust in veterinary advice both ‘in general’ and ‘with respect to nutrition’ than pet owners not feeding RAP. Most pet owners reported that a discussion regarding their pet’s nutrition does not occur at every veterinary appointment. Discussion Pet owners feeding a RAP diet have lower trust in veterinary advice than pet owners not feeding a RAP diet. Owners feeding RAP are more reliant on online resources than their own veterinarian in deciding what and how much RAP to feed. Pet owners perceive that nutrition is not discussed at most veterinary appointments. Therefore, there is room for improvement in the veterinarian-client communication with regards to nutrition.

Controlling Hydrogenation of Graphene on Ir(111)

Balog, Richard; Andersen, Mie; Jørgensen, Bjarke

2013-01-01

Combined fast X-ray photoelectron spectroscopy and density functional theory calculations reveal the presence of two types of hydrogen adsorbate structures at the graphene/ Ir(111) interface, namely, graphane-like islands and hydrogen dimer structures. While the former give rise to a periodic...... pattern, dimers tend to destroy the periodicity. Our data reveal distinctive growth rates and stability of both types of structures, thereby allowing one to obtain well-defined patterns of hydrogen clusters. The ability to control and manipulate the formation and size of hydrogen structures on graphene...

2017-10-01

Owners of free-ranging domestic cats (Felis catus) are under increasing pressure to keep their pet contained within their house or yard, in an effort to reduce adverse impacts on cat welfare, ecosystem biodiversity and neighbourhoods. We conducted a randomised online experiment to assess the effectiveness of two persuasive messages to encourage cat owners to contain their pets. A total of 512 Australian cat owners, who currently do not contain their cats, were randomly assigned to view one of three short video messages: one framed to highlight the negative impact of cats' on wildlife and biodiversity ('wildlife protection' frame), one framed to highlight the health and safety benefits of keeping cats contained ('cat benefit' frame), and a control message focused on general information about cats ('neutral' frame). We assessed the impact of these video messages on two post-treatment outcome variables: (1) the intention of owners to contain their cat; and (2) the adoption of containment practices, based on a 4-week follow-up survey. Mediation analysis revealed both the 'wildlife protection' and 'cat benefit' messages increased owners' motivation to contain their cat and their beliefs that they could effectively contain their cat to achieve the desired outcomes (response efficacy). In turn, higher levels of motivation and response efficacy predicted increased cat containment intentions and increased adoption of cat containment. In addition, the response efficacy effects of the 'cat benefit' message were strengthened by the cat owner's bond to their pet, suggesting audience segmentation may improve the effectiveness of interventions. Implications for future intervention development are discussed. Copyright © 2017 Elsevier B.V. All rights reserved.

Forest owners as fuelwood sellers

International Nuclear Information System (INIS)

Ripatti, P.

2003-01-01

Background features, goals of forest ownership, and forestry behaviour of forest owners who sell fuelwood are considered. The study is based on a sample of 4819 forest holdings collected by mail-inquiry in the 1999. The fuelwood assortments have not been segmented in the data, but fuelwood rerers to chopped firewood, poles, split firewood and chips sold during the period 1994-98. Also, the data does not bring out whether the forest owner has sold his or hers fuelwood straight to the end-user or to a professional trading merchant. The amount of forest owners who sold fuelwood at least once in the years 1994-98 was 33 000, i.e., 11 per cent of all private forest owners. The average sale quantity of fuelwood was 27 stacked cubic metres. The total amount sold fuelwood was 0.9 million stacked cubic metres or approximately 0.6 million solid cubic metres per year. The average size of forest holdings of forest owners who sell firewood was 59 hectares, so they clearly owned larger holdings than on average. The proportion farmers, men and owners who live in rural areas more often were also greater than on average. In addition, proportions of multiobjective, owners who underline both monetary and amenity benefits of their forest ownership, and self-employed forest owners, owners who underline timber sale revenues and self-employment opportunities in their forests, were greater than on average. As a timber sellers and as a silvicultural actors owners who sold fuelwood can be described as a self-initiating and active group of private forest owners. No less than 90 per cent of them made at least one commercial timber sale, and two-thirds at least one delivery sale in the years 1994-98. In addition, 58 per cent of forest holdings owned by fuelwood sellers carried out tending of young stands, and 60 per cent had harvested energy wood. These proportions were clearly greater than for forest holdings as an average. (orig.)

Helms, Timothy D; Bain, Melissa J

2009-04-01

To evaluate whether dog owners who are legally considered guardians are more attached to their dogs than those who are not. Cross-sectional study. Dog owners from northern California. 274 dog owners completed a standardized survey while visiting full-service veterinary and mobile vaccination clinics in a city in which dog owners were legally designated as owner/guardian and in another city in which no such designation was made. Degree of owner attachment to their dog was assessed with a standardized scale. The degree to which owners were attached to their dog was associated with city of residence, owner age, and whether owners were completely satisfied with their dog's behavior. Owners residing in the guardian city had a lower attachment score. There was no significant difference in the percentage of dogs vaccinated against rabies in each city, nor was there any difference in the percentage of licensed dogs. Attachment scores did not differ between participants who visited mobile versus free-standing clinics. Owners with > 1 dog in their household reported a higher degree of attachment to the study dog than did owners of 1 dog. Dog owners residing in a city where owners were legally designated as an owner/guardian were no more attached to their dog than those living in a city without such a designation. Although results did not indicate a negative impact of the term guardian, its use was not associated with an enhanced bond between owner and dog.

Hydrogen control in the System 80+TM ALWR design

International Nuclear Information System (INIS)

Schneider, R.E.; Jacob, M.C.; Carpentino, F.L.; Wachowiak, R.M.

2004-01-01

This paper provides an assessment of the features built into the System 80 +TM Advanced Light Water Reactor (ALWR) design for controlling hydrogen concentration during a hypothetical severe accident. Although the significantly larger System 80 + containment volume serves to passively maintain the global average below detonable limits, the design incorporates a Hydrogen Mitigation System (HMS) to further reduce the local hydrogen concentration. The HMS consists of a large number of hydrogen ignitors distributed within the containment to selectively burn-off hydrogen at low concentrations. The criteria for the placement of these igniters are discussed along with an assessment of the effectiveness of the igniters to control the hydrogen concentrations. This assessment, which was performed using the generalized containment model of the MAAP 4 code, evaluated the potential for hydrogen build-up in the containment and calculated the best-estimate response of the igniters.

Resolution of Unresolved Safety Issue A-48, ''Hydrogen control measures and effects of hydrogen burns on safety equipment''

International Nuclear Information System (INIS)

Ferrell, C.M.; Soffer, L.

1989-09-01

Unresolved Safety Issue (USI) A-48 arose as a result of the large amount of hydrogen generated and burned within containment during the Three Mile Island accident. This issue covers hydrogen control measures for recoverable degraded-core accidents for all boiling-water reactors (BWRs) and those pressurized-water reactors (PWRs) with ice-condenser containments. The Commission and the nuclear industry have sponsored extensive research in this area, which has led to significant revision of the Commission's hydrogen control regulations, given in Title 10, Code of Federal Regulations, Part 50 (10 CFR 50), Section 50.44. BWRs having Mark I and II containments are presently required to operate with inerted containment atmospheres that effectively prevent hydrogen combustion. BWRs with Mark III containments and PWRs with ice-condenser containments are now required to be equipped with hydrogen control systems to protect containment integrity and safety systems inside containment. Industry has chosen to use hydrogen igniter systems to burn hydrogen produced in a controlled fashion to prevent damage. An independent review by a Committee of the National Research Council concluded that, for most accident scenarios, current regulatory requirements make it highly unlikely that hydrogen detonation would be the cause of containment failure. On the basis of the extensive research effort conducted and current regulatory requirements, including their implementation, the staff concludes that no new regulatory guidance on hydrogen control for recoverable degraded-core accidents for these types of plants is necessary and that USI A-48 is resolved

Survey of residential heat pump owner experience in Canada

1985-11-11

Heat pump owners in 7 Canadian cities were surveyed to establish installation costs, repair costs and frequencies, and customer satisfaction with heat pump systems as a function of region, installing contractor, manufacturer, model, year of installation and system type. The following summarizes the major findings of the study. Most Canadian heat pumps are retrofit installations in existing homes. The majority of these heat pumps have either supplemented or replaced an oil furnace. The average age of heat pumps is 2.5 years. The median size of heat pumps installed is 2.5 tons. The three most popular brands by order of prevalence are York, Carrier and General Electric. Only about one-fifth of heat pump owners have purchased service contracts. Two-thirds of the heat pumps have never needed repairs. Eighty-three percent of heat pump owners have never incurred any repair costs; and of those that have, about half spent $100 or less. The most frequent repair problems are refrigerant leaks followed by relays and controls. Corrective actions average about 0.3 per unit year. The owners' evaluation of comfort from their heat pump is generally favourable. About 12% of the owners find the outdoor unit noisy and 10% feel maintenance costs are at a disadvantage. Overall, only 7% of heat pump owners indicated that they would not install a heat pump in their next house. Most heat pump owners are satisfied with their heat pump brand and installer. Owners with systems installed in newer homes are more satisfied with their heat pumps than those who have installed heat pumps in older homes. 3 figs., 93 tabs.

Social referencing in dog-owner dyads?

Science.gov (United States)

Merola, I; Prato-Previde, E; Marshall-Pescini, S

2012-03-01

Social referencing is the seeking of information from another individual to form one's own understanding and guide action. In this study, adult dogs were tested in a social referencing paradigm involving their owner and a potentially scary object. Dogs received either a positive or negative message from the owner. The aim was to evaluate the presence of referential looking to the owner, behavioural regulation based on the owner's (vocal and facial) emotional message and observational conditioning following the owner's actions towards the object. Most dogs (83%) looked referentially to the owner after looking at the strange object, thus they appear to seek information about the environment from the human, but little differences were found between dogs in the positive and negative groups as regards behavioural regulation: possible explanations for this are discussed. Finally, a strong effect of observational conditioning was found with dogs in the positive group moving closer to the fan and dogs in the negative group moving away, both mirroring their owner's behaviour. Results are discussed in relation to studies on human-dog communication, attachment and social learning.

Improved hydrogen monitoring helps control corrosion

International Nuclear Information System (INIS)

Strauss, S.D.

1985-01-01

Hydrogen analyzers have long been used for corrosion monitoring in both fossil-fired boilers and nuclear steam generators. The most recent stimulus for hydrogen monitoring has been provided by cracking of recirculation piping in water reactors. This paper examines the Hydran 202N, which represents an adaption of one instrument that has been used to monitor the degradation of transformer oils and fiberoptic cables. The sensing probe consists of a flow-through cell, an isolating membrane, and a miniature hydrogen/air fuel cell. The use of Hydran 202N at several fossil-fired and nuclear plants is described and the fossilplant application related to the effectiveness of water-chemistry control for a 400 psig oil-fired boiler is examined at a refinery

The efficacy of radioiodine treatment of feline hyperthyroidism is well established; however, limited information is known about owners' perceptions or experiences of radioiodine. This study aimed to examine factors that influence owner treatment choices and their opinions following radioiodine. Surveys were sent to owners of cats referred for radioiodine treatment between 2002 and 2011 (radioiodine group; 264 cats) and owners of non-radioiodine-treated hyperthyroid cats seen at first-opinion practices (control group; 199 cats). The response rate was 67.0% (310 returned: 175 radioiodine, 135 control). Of 135 controls, 72 (53.3%) were unaware of radioiodine as a treatment option. Owners of cats ⩾15 years old and uninsured cats were less likely to pursue radioiodine. Cost of treatment, travel distance, potential human or animal health risks and waiting periods for radioiodine had a low impact on owners' treatment choice. Owners reported a moderate level of concern about treatment hospitalisation length, which included (158 respondents) the possibility of the cat being unhappy 130 (82.3%), owner missing the cat 102 (64.6%), inappetence 50 (31.6%), other pets missing the cat 32 (20.3%), development of co-morbid disease 28 (17.7%) and side effects 25 (15.8%). Owners assessed their cat's quality of life on a scale of 1 (very poor) to 10 (excellent), as 4 (4) (median [interquartile range]) pre-radioiodine (134 respondents) and 9 (2) post-radioiodine (131 respondents). Of 132 respondents, 121 (91.7%) were happy with their decision to choose radioiodine. The results of this questionnaire may assist veterinarians in addressing common owner concerns when discussing radioiodine as a treatment option for hyperthyroidism. © ISFM and AAFP 2014.

We examined the marketing strategies for local vapor stores in a large metropolitan area in Oklahoma. Vapor store owners or managers (n = 33) participated in individual interviews regarding marketing practices in 2014. We asked owners about their marketing strategies and the groups they targeted. We transcribed the interviews and analyzed them for themes. Store owners used a variety of marketing strategies to bring new customers to their stores and keep current customers coming back. These marketing strategies showed many parallels to tobacco industry strategies. Most owners engaged in some form of traditional marketing practices (e.g., print media), but only a few used radio or television advertising because of budget constraints. Owners used social media and other forms of electronic communication, pricing discounts and specials, and loyalty programs. Owners also had booths at local events, sponsored community events, and hosted them in their stores. Owners attempted to target different groups of users, such as college students and long-term smokers. Local vapor store marketing practices closely resemble current and former tobacco industry marketing strategies. Surveillance of marketing practices should include local and Web-based strategies.

Laser controlled magnetism in hydrogenated fullerene films

Makarova, Tatiana L.; Shelankov, Andrei L.; Kvyatkovskii, Oleg E.; Zakharova, Irina B.; Buga, Sergei G.; Volkov, Aleksandr P.

2011-01-01

Room temperature ferromagnetic-like behavior in fullerene photopolymerized films treated with monatomic hydrogen is reported. The hydrogen treatment controllably varies the paramagnetic spin concentration and laser induced polymerization transforms the paramagnetic phase to a ferromagnetic-like one. Excess laser irradiation destroys magnetic ordering, presumably due to structural changes, which was continuously monitored by Raman spectroscopy. We suggest an interpretation of the data based on first-principles density-functional spin-unrestricted calculations which show that the excess spin from mono-atomic hydrogen is delocalized within the host fullerene and the laser-induced polymerization promotes spin exchange interaction and spin alignment in the polymerized phase.

Characteristics of the human-animal bond can be influenced by both owner-related and pet-related factors, which likely differ between species. Three studies adapted the Monash Dog-Owner Relationship Scale (MDORS) to permit assessment of human-cat interactions as perceived by the cat's owner. In Study 1293 female cat owners completed a modified version of the MDORS, where 'dog' was replaced with 'cat' for all items. Responses were compared with a matched sample of female dog owners. A partial least squares discriminant analysis revealed systematic differences between cat and dog owners in the Dog (Cat)-Owner Interaction subscale (MDORS subscale 1), but not for Perceived Emotional Closeness or Perceived Costs (Subscales 2 and 3). Study 2 involved analysis of free-text descriptions of cat-owner interactions provided by 61 female cat owners. Text mining identified key words which were used to create additional questions for a new Cat-Owner Interaction subscale. In Study 3, the resulting cat-owner relationship scale (CORS) was tested in a group of 570 cat owners. The main psychometric properties of the scale, including internal consistency and factor structure, were evaluated. We propose that this scale can be used to accurately assess owner perceptions of their relationship with their cat. A modified scale, combining items from the CORS and MDORS (a C/DORS), is also provided for when researchers would find it desirable to compare human-cat and human-dog interactions.

Owners' direct gazes increase dogs' attention-getting behaviors.

Science.gov (United States)

Ohkita, Midori; Nagasawa, Miho; Kazutaka, Mogi; Kikusui, Takefumi

2016-04-01

This study examined whether dogs gain information about human's attention via their gazes and whether they change their attention-getting behaviors (i.e., whining and whimpering, looking at their owners' faces, pawing, and approaching their owners) in response to their owners' direct gazes. The results showed that when the owners gazed at their dogs, the durations of whining and whimpering and looking at the owners' faces were longer than when the owners averted their gazes. In contrast, there were no differences in duration of pawing and likelihood of approaching the owners between the direct and averted gaze conditions. Therefore, owners' direct gazes increased the behaviors that acted as distant signals and did not necessarily involve touching the owners. We suggest that dogs are sensitive to human gazes, and this sensitivity may act as attachment signals to humans, and may contribute to close relationships between humans and dogs.

Universally applicable design concept of stably controlling an HTGR-hydrogen production system

International Nuclear Information System (INIS)

Hada, Kazuhiko; Shibata, Taiju; Nishihara, Tetsuo; Shiozawa, Shusaku

1996-01-01

An HTGR-hydrogen production system should be designed to have stable controllability because of a large difference in thermal dynamics between reactor and hydrogen production system and such a control design concept should be universally applicable to a variety of hydrogen production processes by the use of nuclear heat from HTGR. A transient response analysis of an HTGR-steam reforming hydrogen production system showed that a steam generator installed in a helium circuit for cooling the nuclear reactor provides stable controllability of the total system, resulting in avoiding a reactor scram. A survey of control design-related characteristics among several hydrogen production processes revealed the similarity of endothermic chemical reactions by the use of high temperature heat and that steam is required as a reactant of the endothermic reaction or for preheating a reactant. Based on these findings, a system design concept with stable controllability and universal applicability was proposed to install a steam generator as a downstream cooler of an endothermic reactor in the helium circuit of an HTGR-hydrogen production system.

Shareholder, stakeholder-owner or broad stakeholder maximization

OpenAIRE

Mygind, Niels

2004-01-01

With reference to the discussion about shareholder versus stakeholder maximization it is argued that the normal type of maximization is in fact stakeholder-owner maxi-mization. This means maximization of the sum of the value of the shares and stake-holder benefits belonging to the dominating stakeholder-owner. Maximization of shareholder value is a special case of owner-maximization, and only under quite re-strictive assumptions shareholder maximization is larger or equal to stakeholder-owner...

Dog obesity: can dog caregivers' (owners') feeding and exercise intentions and behaviors be predicted from attitudes?

Science.gov (United States)

Rohlf, Vanessa I; Toukhsati, Samia; Coleman, Grahame J; Bennett, Pauleen C

2010-01-01

Dog obesity is a common nutritional disorder affecting up to 40% of the companion animal (pet) dog population in Australia and other developed nations. A clear understanding of factors determining relevant caregiver (owner) behaviors underpins effective treatment for this disorder. The theory of planned behavior can be used to understand factors contributing to human behavior. This article describes research informed by this theory. The research examined relationships between owners' behavioral beliefs and barriers, normative beliefs and perceptions of control, owners' feeding and exercise behaviors toward their dogs, and the body condition scores (BCSs) of dogs. The study recruited a sample of 182 dog and owner dyads. The researcher independently assessed BCSs. Owners completed a questionnaire measuring relevant feeding and exercise beliefs and behaviors. This revealed significant correlations between many psychological variables and BCSs and between psychological variables and specific owner behaviors: for example, the relationship of low levels of intentions to feed appropriately to ambivalent beliefs toward feeding appropriately and low perceived control. Careful consideration of the specific variables identified will permit the development of more effective interventions.

Surface Magnetism of Cobalt Nanoislands Controlled by Atomic Hydrogen.

2017-01-11

Controlling the spin states of the surface and interface is key to spintronic applications of magnetic materials. Here, we report the evolution of surface magnetism of Co nanoislands on Cu(111) upon hydrogen adsorption and desorption with the hope of realizing reversible control of spin-dependent tunneling. Spin-polarized scanning tunneling microscopy reveals three types of hydrogen-induced surface superstructures, 1H-(2 × 2), 2H-(2 × 2), and 6H-(3 × 3), with increasing H coverage. The prominent magnetic surface states of Co, while being preserved at low H coverage, become suppressed as the H coverage level increases, which can then be recovered by H desorption. First-principles calculations reveal the origin of the observed magnetic surface states by capturing the asymmetry between the spin-polarized surface states and identify the role of hydrogen in controlling the magnetic states. Our study offers new insights into the chemical control of magnetism in low-dimensional systems.

Shuttle Gaseous Hydrogen Venting Risk from Flow Control Valve Failure

Drummond, J. Philip; Baurle, Robert A.; Gafney, Richard L.; Norris, Andrew T.; Pellett, Gerald L.; Rock, Kenneth E.

2009-01-01

This paper describes a series of studies to assess the potential risk associated with the failure of one of three gaseous hydrogen flow control valves in the orbiter's main propulsion system during the launch of Shuttle Endeavour (STS-126) in November 2008. The studies focused on critical issues associated with the possibility of combustion resulting from release of gaseous hydrogen from the external tank into the atmosphere during assent. The Shuttle Program currently assumes hydrogen venting from the external tank will result in a critical failure. The current effort was conducted to increase understanding of the risk associated with venting hydrogen given the flow control valve failure scenarios being considered in the Integrated In-Flight Anomaly Investigation being conducted by NASA.

Oxytocin blocks pet dog (Canis familiaris object choice task performance being predicted by owner-perceived intelligence and owner attachment

Directory of Open Access Journals (Sweden)

Jessica Lee Oliva

2016-04-01

Full Text Available A positive association has been found between owner-rated dog cognition and owner-perceived closeness to their dog, using the Perceptions of Dog Intelligence and Cognitive Skills (PoDIaCS survey and the Monash Dog Owner Relationship Scale (MDORS. Oxytocin has been positively associated with bonding in mammals and with non-verbal intelligence in humans and could therefore explain this relationship between owner-rated questionnaires. The aims of this study were to ascertain: i whether a pet dog’s performance on an object choice task (OCT, which objectively measures dogs’ ability to use human non-verbal, social gestures to find a food reward, could be predicted by their owners’ scores on three different surveys: (a the MDORS, (b the Pet Attachment Questionnaire (PAQ, which measures levels of anxious and avoidant attachment styles, and (c a modified version of the PoDIaCS, and ii if intranasal administration of oxytocin to dogs, known to enhance dogs’ performance on such tasks, would disable the ability of an owner to predict their dogs’ performance. It was hypothesized that higher ratings of owner-reported closeness to their dog, and higher ratings of owner-perceived intelligence of their dog, would positively predict dog OCT performance after saline, but not after oxytocin. Seventy-five pet dogs and their owners were recruited to participate in two OCTs, 5-15 days apart, once after the dog received intranasal oxytocin and once after receiving saline. Owners completed the PoDIaCS and another survey relating to pet ownership before OCT 1, and the MDORS and PAQ before OCT 2. After saline administration, scores on the anxious subscale of the PAQ were a negative predictor of dog OCT performance using pointing cues, while subscale 6 of the PoDIaCS, ‘contagion of human emotions’, positively predicted performance using gazing cues. None of the questionnaire subscales were predictive of performance on the OCT after oxytocin administration

A comparison of noxious facilities' impacts for home owners versus renters

International Nuclear Information System (INIS)

Clark, D.E.; Nieves, L.A.

1995-01-01

The siting of noxious facilities, such as hazardous waste facilities, is often vigorously opposed by local residents, and thus it is now common for local residents to be compensated for the presence of the facility. One technique that has been employed to implicitly value noxious facilities is the intercity hedonic approach, which examines the wage and land rent premia between cities that result from the presence of the facility. However, most of the focus has been on the behavior of home owners as opposed to renters. Since these two groups of residents vary on numerous dimensions such as marital status, age, sex, and personal mobility, it would not be surprising to find different marginal valuations of local site characteristics. The authors use 1980 Census data to derive separate estimates for owners and renters of the implicit value placed on eight different types of noxious facilities. They find that renters and owners differ in their response to noxious facilities, although the differences are not systematic. Furthermore, the differences between owners and renters are not primarily due to differential mobility or socio-demographic factors. Controlling those factors decreases the differences between renters' and owners' implicit valuations of noxious facilities by less than 10%. Unmeasured differences between the two groups, such as tastes, risk aversion, or commitment to the community, must account for the remaining difference in valuations. These findings suggest that policymakers should separately consider the responses of owners and renters when estimating noxious facility impacts

Seroepidemiological Study of Toxocariasis in the Owners of Domestic Cats and Dogs in Mashhad, Northeastern Iran

2016-10-01

Full Text Available Background: Toxocariasis is the clinical terms applied to infection of human with Ascarid nematodes in the order Ascaridida, named Toxocara canis and T. cati. Because in recent years in Iran many people desire to keep pets (cats and dogs, and lacking of seroepidemiological study of toxocariasis in Mashhad, we decided to determine the seroprevalence of toxocariasis among people who own cats and dogs in comparison with control group.Methods: A serological study for detection antibodies to Toxocara in two groups (93 cat and dog owners and 93 healthy people as control group was conducted from Feb 2013 to Dec 2013. An ELISA method was employed using determination of IgG antibodies against Toxocara. The serum samples were evaluated for anti-Toxocara antibody, using ELISA technique at Parasitology and Immunology Lab of Imam Reza Hospital of Mashhad. Using a questionnaire, epidemiological factors associated with infection were examined. Data were analyzed using Chi-square test.Results: The seroprevalence of Toxocara antibodies in the pet owners and control group was respectively 20.43% and 1.07%.  47.3% of pet owners were female. Conclusion: Presented data showed the significant difference between seroprevalence of toxocariasis among pet owners and control group. Education of society and in particular pet owners consisting of preventing contamination of the environment with Toxocara eggs is advised.

Controlled delamination of metal films by hydrogen loading

Energy Technology Data Exchange (ETDEWEB)

Nikitin, Eugen

2008-11-18

n this work we quantitatively determine the adhesion energy between metal films and their substrates. Therefore a new controlled buckling technique is established, applying the strong compressive in-plane stress that results in thin films clamped on rigid substrates during hydrogen loading. When the elastic energy stored in the H-loaded thin film exceeds the adhesion energy between film and substrate, delamination occurs. At the onset of delamination, a critical hydrogen concentration, a critical stress value and a critical bending of the substrate are present, which are quantitative measures for the adhesion energy and permit its calculation. As the critical values are determined at the onset of delamination, plastic deformation is negligible, which denies the quantitative determination of adhesion energies in conventional test setups. In multilayer-systems, adhesion energies between substrates and films that hardly absorb hydrogen can be measured by the controlled buckling technique, when the films of interest are coated with hydrogen absorbing films (active layer). The measurements are performed easily and can be repeated under the same test conditions, while variables such as the thickness of the coating materials or the boundary surface structure can be varied and optimized. In this work the adhesion energies of different materials on polycarbonate and niobium on sapphire are investigated. (orig.)

Unleashing their potential: a critical realist scoping review of the influence of dogs on physical activity for dog-owners and non-owners.

Science.gov (United States)

Toohey, Ann M; Rock, Melanie J

2011-05-21

Dog-owners tend to be more physically active than non-owners; however, dogs have also been shown to inhibit physical activity for non-owners, under some circumstances. We conducted a scoping review to identify studies pertaining to the influence of dogs on physical activity for both dog-owners and non-owners, and adopted a critical realist orientation to draw inferences about the positive and negative impact of dogs via their affect on physical and social environments. We identified 35 studies from disparate literatures for review. These studies confirm that dog and owner behaviors affect shared physical and social environments in ways that may influence physical activity patterns, not only among dog-owners but also among non-owners. The direction of influence appears to be most positive in neighborhoods exhibiting high levels of social cohesion, socioeconomic status, perceived safety, dominant culture, or all of these. In disadvantaged neighborhoods, the health of women as well as older adults may be disproportionately affected by dog and owner behavior. While dogs have the potential to increase physical activity for both dog-owners and non-owners, the presence or absence of dogs will not have a standard effect across the physical and social environments of all neighborhoods. Dogs' contributions to shared environments in ways that support physical activity for all must be leveraged. Thus, specific contextual factors must be considered in relation to dogs when planning neighborhood-level interventions designed to support physical activity. We suggest this population health topic merits further investigation.

NRC Information No. 89-44: Hydrogen storage on the roof of the control room

International Nuclear Information System (INIS)

Rossi, C.E.

1992-01-01

During the Region V Chemistry Team Inspection at the Trojan Nuclear Plant the week of April 17, 1989, the inspectors identified a potential safety problem concerning the location of the hydrogen storage facility. Hydrogen is used on pressurized water reactor (PWR) plants for (1) providing a cover gas in the volume control tank, and (2) for cooling the main turbine generator. At boiling water reactor (BWR) plants, hydrogen is also used for cooling the main turbine generator and for injection into the feed system for plants which have implemented hydrogen water chemistry. The Trojan hydrogen storage facility is located on the control room roof which is 30-inch-thick reinforced concrete. The Trojan plant hydrogen facility does not meet guidelines from the standpoint of (1) the separation distance needed between a hydrogen pipe break and the control room ventilation intake to prevent buildup of a flammable or explosive gas mixture inside the control room, and (2) the separation distance needed to prevent damage to safety-related structures resulting from the explosion of an 8,000-scf hydrogen tank

Vapor Store Owner Beliefs and Messages to Customers.

Cheney, Marshall K; Gowin, Mary; Wann, Taylor Franklin

2016-05-01

Electronic cigarette (e-cigarette) use is becoming increasingly popular but little is known about the role of the local vapor store in promoting use and influencing customer attitudes and beliefs about vaping. Thirty-three vapor store owners were interviewed about their personal beliefs and attitudes about e-cigarettes and what they told customers about the health impact of using e-cigarettes. Interviews were recorded then transcribed, coded, and analyzed for themes. Vapor store owners used the internet to obtain information about vaping, most often from YouTube and industry sources. Owners often did not have the training to critically evaluate research studies posted on the internet. Owners promoted vaping as a healthier alternative to smoking and often compared it to a medical treatment. Owners considered ingredients in the e-liquid as safe to use if it was safe to eat and discussed other foods vapor ingredients were found in. Owners also discussed the safety of secondhand vapor. Owners described the health impact of nicotine in e-liquid by comparing nicotine to caffeine and promoted the nicotine in e-liquid as coming from vegetables rather than tobacco. Finally, owners talked about vaping as a habit rather than a continued addiction to nicotine. Local store owners are an important source of health information for current and potential e-cigarette users but their messages to customers may be based on incomplete or misinterpreted information. Understanding local store owner messages to customers in addition to internet-based messages is an important area for future public health research. © The Author 2015.

A weight loss protocol and owners participation in the treatment of canine obesity

Directory of Open Access Journals (Sweden)

Carciofi Aulus Cavalieri

2005-01-01

Full Text Available The success of a weight loss program for pets depends on the owners collaboration. Their compliance is fundamental in establishing the correct food management. The objective of this study was to compare the effectiveness of a weight loss program in two groups of dogs, one maintained under experimental conditions and the other with their owners. The same hypocaloric food was used to feed all animals, the amount being restricted to 60% of the estimated maintenance energy requirement for a 15% reduction of the present body weight of the dog. The animals were followed during 90 days. A standard questionnaire was used to study the owners' perception of obesity and its treatment. The protocol and the diet were found to be effective. The control dogs had an average weight loss of 1.39% per week. Dogs with owners lost on average 0.75% of their body weight per week, a statistically lower result (P<0.05, suggesting that the owners did not follow the treatment closely. The owners were clearly satisfied with the results that were obtained, even with this modest weight loss. The questionnaires were shown to be an important tool in determining the causes of canine obesity, as well as in the follow-up of the treatment.

Identification of intrinsic catalytic activity for electrochemical reduction of water molecules to generate hydrogen

KAUST Repository

Shinagawa, Tatsuya

2015-01-01

Insufficient hydronium ion activities at near-neutral pH and under unbuffered conditions induce diffusion-limited currents for hydrogen evolution, followed by a reaction with water molecules to generate hydrogen at elevated potentials. The observed constant current behaviors at near neutral pH reflect the intrinsic electrocatalytic reactivity of the metal electrodes for water reduction. This journal is © the Owner Societies.

[Equine dentistry: Survey on Swiss horse owners].

Schiesser, E; Geyer, H; Kummer, M; Jackson, M

2017-08-01

The interest in equine dentistry has significantly increased in the last 15 years. On the part of the veterinarians as well as of the horse owners there is a strong attention to the topic. The aim of the questionnaire was to investigate amongst horse owners what their level of information and preferences about dental treatment are and how they are implemented. The questionnaire was translated into the three national languages and included 20 questions about level and sources of information, frequency of treatments and the horse owner's stance over sedation of the animals. With a return rate of 45% (1'466 of 3'250 sent questionnaires) significant conclusions could be drawn. Horse owners showed a strong demand for clarification regarding tooth problems, the causes, consequences and methods of treatment. More than half of the owners considered themselves not well informed. The treating person was in 66.7% a veterinarian with a special education. Horse owners indicated that information circulated most frequently by word of mouth recommendations and they explicitly wished information from professional and reliable sources. The questionnaire provided a clear result about current equine dental treatments. We suggest that they should be performed by veterinarians only with a special education.

Experiences of model year 2011 Dodge and Jeep owners with collision avoidance and related technologies.

Science.gov (United States)

Cicchino, Jessica B; McCartt, Anne T

2015-01-01

Crash avoidance technologies have the potential to prevent or mitigate many crashes, but their effectiveness depends on drivers' acceptance and proper use. Owners of 2011 Dodge Charger, Dodge Durango, and Jeep Grand Cherokee vehicles were interviewed about their experiences with their vehicles' technologies. Interviews were conducted in April 2013 with 215 owners of Dodge and Jeep vehicles with adaptive cruise control and forward collision warning and 215 owners with blind spot monitoring and rear cross-path detection. Most owners said that they always keep each collision avoidance technology turned on, and more than 90% of owners with each system would want the technology again on their next vehicle. The majority believed that the systems had helped prevent a collision; this ranged from 54% of drivers with forward collision warning to more than three-quarters with blind spot monitoring and rear cross-path detection. Some owners reported behavioral changes with the systems, but over-reliance on them is not prevalent. Reported use of the systems varied by the age and gender of the driver and duration of vehicle ownership to a greater degree than in previous surveys of luxury Volvo and Infiniti vehicles with collision avoidance technologies. Notably, drivers aged 40 and younger were most likely to report that forward collision warning had alerted them multiple times and that it had prevented a collision and that they follow the vehicle ahead less closely with adaptive cruise control. Reports of waiting for the alert from forward collision warning before braking were infrequent but increased with duration of ownership. However, these reports could reflect confusion of the system with adaptive cruise control, which alerts drivers when braking is necessary to maintain a preset speed or following distance but a crash is not imminent. Consistent with previous surveys of luxury vehicle owners with collision avoidance technologies, acceptance and use remains high among

Supporting CANDU operators-CANDU owners group

International Nuclear Information System (INIS)

Collingwood, B.R.

1997-01-01

The CANDU Owners Group (COG) was formed in 1984 by the Canadian CANDU owning utilities and Atomic Energy of Canada limited (AECL). Participation was subsequently extended to all CANDU owners world-wide. The mandate of the COG organization is to provide a framework for co-operation, mutual assistance and exchange of information for the successful support, development, operation, maintenance and economics of CANDU nuclear electric generating stations. To meet these objectives COG established co-operative programs in two areas: 1. Station Support. 2. Research and Development. In addition, joint projects are administered by COG on a case by case basis where CANDU owners can benefit from sharing of costs

Neutering of cats and dogs in Ireland; pet owner self-reported perceptions of enabling and disabling factors in the decision to neuter

Directory of Open Access Journals (Sweden)

Martin J. Downes

2015-08-01

Full Text Available Background. Failure among pet owners to neuter their pets results in increased straying and overpopulation problems. Variations in neutering levels can be explained by cultural differences, differences in economic status in rural and urban locations, and owner perceptions about their pet. There are also differences between male and female pet owners. There is no research pertaining to Irish pet owner attitudes towards neutering their pets. This paper identified the perceptions of a sample of Irish cat and dog owners that influenced their decisions on pet neutering.Methods. This study was conducted using social science (qualitative methods, including an interview-administered survey questionnaire and focus group discussions. Data was coded and managed using Nvivo 8 qualitative data analysis software.Results. Focus groups were conducted with 43 pet (cats and dogs owners. Two major categories relating to the decision to neuter were identified: (1 enabling perceptions in the decision to neuter (subcategories were: controlling unwanted pet behaviour; positive perceptions regarding pet health and welfare outcomes; perceived owner responsibility; pet function; and the influence of veterinary advice, and (2 disabling perceptions in the decision to neuter (subcategories were: perceived financial cost of neutering; perceived adequacy of existing controls; and negative perceptions regarding pet health and welfare outcomes.Discussion. Pet owner sense of responsibility and control are two central issues to the decision to neuter their pets. Understanding how pet owners feel about topics such as pet neutering, can help improve initiatives aimed at emphasising the responsibility of population control of cats and dogs.

Owens, Kimberly S; Kirwan, Jeral R; Lounsbury, John W; Levy, Jacob J; Gibson, Lucy W

2013-01-01

Drawing on prior occupational choice research on entrepreneurs and self-employed business owners, we examined personality predictors of their occupational business success and work satisfaction. PARTICIPANTS AND PROCEDURES: A sample of 147 small business owners completed a web-based assessment of 14 work-related personality traits--adaptability, autonomy, competitiveness, dependability, emotional resilience, goal-setting, optimism, persistence, risk tolerance, self-promotion, networking, and tolerance for financial insecurity, work-based locus of control, and work drive--and three self-reported indices of business success--revenue growth, profit growth, and income growth--as well as multiple facets of individual satisfaction. Criterion variables included composite business success and overall satisfaction. Ten traits correlated with business success. The top four personality predictors of success--goal-setting, social networking, emotional resilience, and work drive--together accounted for 16% of the variance. Similarly, 12 of 14 personality traits were positively related to overall satisfaction. The top three personality predictors of satisfaction--optimism, work-based locus of control, and work drive--accounted for 29% of the variability in satisfaction. An expectancy analysis revealed that the percent of participants who reported at least a 20% increase in sales and profits the preceding year was 26% versus 54% for individual scoring in the lower and upper third of a personality composite measure. Results carry implications for future research, and have direct, practical applications for prospective and current entrepreneurs and self-employed owners of small businesses.

A model of business success was developed with motivational resources (locus of control, self-efficacy, achievement motivation, and self-reported personal initiative) and cognitive resources (cognitive ability and human capital) as independent variables, business owners' elaborate and proactive planning as a mediator, and business size and growth as dependent variables. Three studies with a total of 408 African micro and small-scale business owners were conducted in South Africa, Zimbabwe, and Namibia. Structural equation analyses partially supported the hypotheses on the importance of psychological planning by the business owners. Elaborate and proactive planning was substantially related to business size and to an external evaluation of business success and was a (partial) mediator for the relationship between cognitive resources and business success. The model carries important implications for selection, training, and coaching of business owners. (c) 2007 APA

This paper gives a control oriented modeling of an electrolyzer, as well as the ancillary system for the hydrogen production process. A Causal Ordering Graph of all necessary equations has been used to illustrate the global scheme for an easy understanding. The model is capable of characterizing the relations among the different physical quantities and can be used to determine the control system ensuring efficient and reliable operation of the electrolyzer. The proposed control method can manage the power flow and the hydrogen flow. The simulation results have highlighted the variation domains and the relations among the different physical quantities. The model has also been experimentally tested in real time with a Hardware-In-the-Loop Simulation before being integrated in the test bench of the active wind energy conversion system. (author)

Surface properties of hydrogenated nanodiamonds: a chemical investigation.

Girard, H A; Petit, T; Perruchas, S; Gacoin, T; Gesset, C; Arnault, J C; Bergonzo, P

2011-06-28

Hydrogen terminations (C-H) confer to diamond layers specific surface properties such as a negative electron affinity and a superficial conductive layer, opening the way to specific functionalization routes. For example, efficient covalent bonding of diazonium salts or of alkene moieties can be performed on hydrogenated diamond thin films, owing to electronic exchanges at the interface. Here, we report on the chemical reactivity of fully hydrogenated High Pressure High Temperature (HPHT) nanodiamonds (H-NDs) towards such grafting, with respect to the reactivity of as-received NDs. Chemical characterizations such as FTIR, XPS analysis and Zeta potential measurements reveal a clear selectivity of such couplings on H-NDs, suggesting that C-H related surface properties remain dominant even on particles at the nanoscale. These results on hydrogenated NDs open up the route to a broad range of new functionalizations for innovative NDs applications development. This journal is © the Owner Societies 2011

Client satisfaction gained great importance in health care as a measurement of service quality. One of the most popular methods to evaluate client satisfaction is the SERVQUAL inquiry which measures service quality by evaluating client expectations and services towards a service in five dimensions: Tangibles, Empathy, Assurance, Reliability and Responsiveness. In order to evaluate if owners of pets with cancer constitute a distinctive group from the general pet owner population and if these differences were perceived by the hospital staff we applied a SERVQUAL questionnaire to 51 owners of pet with cancer, 68 owners from the general pet population and 14 staff members. Owners of oncologic pets had different expectations of an ideal service granting importance to Assurance questions (6.75 vs 6.5, p= 0.045) while showing unmet needs in Reliability and Empathy dimensions. Veterinarians failed to understand these specificities and over evaluated characteristics of Tangible dimension (6.75 vs 6.25, p=0.027). Owners of pet with cancer seem to constitute a specific subpopulation with special needs and veterinary staff should invest resources towards Assurance instead of privileging tangible aspects of veterinary services. By aligning professionals expectations with those of pet owners veterinarians can achieve better client satisfaction, improved compliance and stronger doctor-owner relationships.

Efficient operation results from a proper control strategy. In the operation and performance of a Proton Exchange Membrane Fuel Cell (PEMFC), the hydrogen gas flow rate is one of the most essential control parameter in addition to operating pressure, water management, temperature and humidity. This is because of the high cost and amount of energy are required to produce the purity hydrogen gas. In this paper, a Proportional Integral Derivative (PID) feedback control system is used to control the hydrogen flow rate. A strategy is adapted to balance the hydrogen use based on the loading requirements, especially during start-ups and sudden power demands. This system is implemented using National Instrument (NI) devices powered by the LabVIEW program. This is due to its simplicity and customization flexibility for measuring, processing and recording data. Designed structure allows the real-time implementation of a robust control law that is able to address the related nonlinearities and uncertainties without incurring a heavy computational load for the controller algorithm. While it facilitating a fast sampling rate according to the needs of the power system. Test results from the controller show that the new fuel control system provides good performance by reducing the amount of wasted hydrogen gas compared with that of the previous open loop system by 30 % to over 80 % saved by the varied load. This improvement is beneficial for any PEMFC that experiences fluctuating power demand, especially for vehicle applications. (author)

OBJECTIVE To determine the effect of different types of classical music played during a veterinary visit on dog behavior and owner satisfaction. DESIGN Prospective randomized controlled study. ANIMALS 74 dogs examined at a veterinary teaching hospital. PROCEDURES Dogs examined for a wellness visit, presurgical health evaluation, or nonurgent illness were exposed to 1 of 3 treatments (modified classical music, the same music in its original format, and no music [control]) while in the examination room. Owners completed a standardized survey regarding the dog's behavior and their satisfaction with the visit. Clinicians completed a separate standardized survey regarding the dog's behavior. Information regarding monetary charges, procedures performed, diagnoses, and physiologic variables was obtained from the electronic medical record after the appointment. RESULTS Owners rated their dog's anxiety level in the waiting room greater than that in the examination room regardless of treatment. Mean anxiety and aggression scores of dogs during the physical examination as rated by owners were significantly greater than those assigned by clinicians. Visit satisfaction for owners exposed to original classical music was significantly greater than that for owners not exposed to music. CONCLUSIONS AND CLINICAL RELEVANCE Results suggested placing a pet and its owner into an examination room instead of a waiting room immediately after clinic arrival may ameliorate pet anxiety during the veterinary visit. Playing classical music at a low volume can be a simple and cost-effective way to improve owner satisfaction with the veterinary visit. Further research is necessary to determine the effects of music on pet anxiety.

Full Text Available Abstract Background Little is known about the variables underlying small business owners' behavioural intentions toward workplace health and safety. This project explores the relationship between three mediating variables (Attitude Toward Safety, Subjective Norm and Perceived Behavioural Control and owners' Intentions Toward Safety, following the Theory of Planned Behaviour. We also investigate the role of beliefs underlying each mediating variable. Methods Seven hundred businesses (5–50 employees were randomly selected from 4084 eligible companies in a manufacturing business database (SIC codes 24 to 39. The 348 respondents are on average 51 yrs of age, 86% male, 96% white and have 2 to 4 years of post-secondary school. Results All three mediator variables are significantly correlated with Intentions Toward Safety; Attitude Toward Safety shows the strongest correlation, which is confirmed by path analysis. Owners with higher attitudes toward safety have a higher probability of believing that improving workplace health and safety will make employees' healthier and happier, show that they care, increase employee productivity, lower workers' compensation costs, increase product quality and lower costs. Conclusion These results suggest that interventions aimed at increasing owners' health and safety intentions (and thus, behaviours should focus on demonstrating positive employee health and product quality outcomes.

Maruyama, Ryuichiro

2002-01-01

A membrane electrode assembly (MEA) was fabricated using proton conductive hydrogensulfated fullerenol (C 60 (OSO 3 H) n (OH) n ). Rate-controlled mass flow of hydrogen was performed by applying voltage to both electrodes of the MEA without humidification. The amount of the electrochemically transported hydrogen through the MEA increased as the applied current increased, obeying Faraday's law. Residual gas analysis of the transported hydrogen showed that the transported hydrogen contains trace amounts of water less than 1%

Weekly changes of power supplier - consequences for the network owner

International Nuclear Information System (INIS)

Graabak, Ingeborg

1997-01-01

In Norway, it is expected that owners of electric distribution networks will be required to make it possible for the customers to change supplier each week. This report examines what consequences such a requirement will have for the network owners. An inquiry among nine network owners shows that at present changing supplier implies a great deal of manual work on the part of the network owner since many do not have computer based tools adapted to handle the situation. If the number of weekly changes of suppliers does not increase beyond a few percent of the network owner's total number of customers over 1 to 3 years, the network owner can cope with the situation. However, if for some reason the increase becomes larger, many network owners will have great problems because they lack the necessary computer tools. 1 table

The aim of this study was to evaluate the perceptions and opinions of Canadian pet owners about anaesthesia, pain and surgery in dogs and cats. Six Canadian veterinary hospitals participated. Each practice received 200 copies of a questionnaire that were distributed to pet owners. Questions regarding the use of analgesics, anaesthesia, surgery and onychectomy (cats) were included. Responses were transformed into ordinal scores and analysed with a Cochran-Mantel-Haenszel test. A total of 849 out of 1200 questionnaires were returned. Owners believed more frequently that analgesics are needed for surgical procedures than for the medical conditions. Owners rated as very important/important: "knowing what to expect during illness/injury/surgery" (99·3%), "being assured that all necessary analgesic drugs/techniques will be used" (98·6%), "being informed about procedures/risk" (98·5%), and having a board-certified anaesthesiologist (90·5%). Most owners agreed/partly agreed that pain impacts quality of life (94·2%), and affects their pet's behaviour (89·5%). Most respondents (69%) were women; they were significantly more concerned than men about anaesthesia, pain, cost and client-communication. Cat owners believed that analgesics were necessary for some procedures/conditions significantly more often than canine-only owners. Pet owners with previous surgery disagreed more frequently that "pain after surgery can be helpful" and that "pain in animals is easy to recognize" than those without previous surgery. Most owners think onychectomy should be banned in cats (56·4%). This study identified important areas of client communication regarding pain and its control in pets. © 2017 British Small Animal Veterinary Association.

Analysis of Hydrogen Control Strategy Using Igniter during Severe Accident

Lee, Sung Bok; Kim, Hyeong Taek; Lee, Keo Hyoung

2008-01-01

The Severe Accident Management Guidelines (SAMGs) for the operating pressurized water reactor (PWR) have been completed within 2006. Among the SAMG strategies, mitigation-07 is the most important strategy for managing a severe accident of a PWR in order to reduce containment hydrogen. The fastest way to reduce the containment hydrogen concentration is to intentionally ignite the hydrogen. For this strategy, igniters exist in Optimized Power Reactor 1000 (OPR 1000) to burn hydrogen for a severe accident. For using the igniters during a severe accident, the adverse effects such as the explosion of the hydrogen mixture should be considered for containment integrity. However, an applicable discrimination method to activate the igniters does not exist, so that the hydrogen control strategy using the igniters cannot be chosen during a severe accident. Thus, this study focused on suggesting an applicable discrimination method to carry out the strategy of using the igniters. In this study, the specific plant used for this analysis is Ulchin Unit 5 and 6, OPR 1000 plant, in Korea

Full Text Available Abstract Background External radiation therapy (RT has been available for small animals in Sweden since 2006. This study was designed to obtain information on owner experiences and perceptions related to RT of cancer in their dogs. Another survey was used to determine the attitudes about use of RT in a group of Swedish veterinarians. Their responses were analyzed and compared to their level of knowledge of oncology and RT. Methods Owners of all dogs (n = 23 who had undergone RT for malignancy at Jönköping Small Animal Hospital between March 2006 to September 2007 were interviewed. A questionnaire was given to a selected group of veterinarians. Results All 23 owners responded. All owners thought that their dog did well during RT and most that their dog was also fine during the following phase when acute RT-related skin reactions occur and heal. Three owners stated that their dog had pain that negatively impacted quality of life because of radiation dermatitis. Five owners reported that RT positively impacted quality of life of the dog during the first weeks after RT because palliation was achieved. The owners were not disturbed by the efforts required of them. All but one owner (22 of 23 stated that they would make the same decision about RT again if a similar situation occurred. The most important factor for this decision was the chance to delay occurrence of tumour-related discomfort. The chance for cure was of less importance but still essential, followed by expected side effects. Time commitments, travel, number of treatments required and financial cost; all had low impact. The veterinarian survey showed that less background knowledge of small animal oncology/RT was associated with more negative expectations of RT for small animals. Conclusion The results show that for these owners, RT was a worthwhile treatment modality and that the discomfort for the dog was manageable and acceptable relative to the benefits.

Full Text Available Introduction & Objective: Many Iranian families manage to keep pets at home. Examining psychological consequences and personality traits of pet owners is important. The aim of this study was to examine mental health status and personality traits of pet owners. Materials & Methods: In this descriptive study, 612 pet owners (143 cat owners, 162 dog owners, 155 bird owners and 152 other pet owners were asked to complete General Health Questionnaire (GHQ and IPIP Personality Scale from January to December 2006. Results: Bird owners had the highest (234 cases (38.3% and other pet owners had the lowest (129 cases (42.3% mental health problems. In general, 188 cases (30.7% of all groups had mental health problems. 122 cases (20% of them had somatic compliance, 182 cases (29.7% had anxiety, 149 cases (24.3% had social dysfunction and 84 cases (13.7% had depression. Bird owners had significant high level of social dysfunction than other pet owners. With respect to personality traits, dog owners had low level of agreeableness and openness to experience than other groups. Other pet owners had high level of emotional stability than other groups. Conclusion: Contrary to other countries, it seems that having a pet in home enhances the probability of mental disorders in Iran. It is possible that lower mental health persons were keeping pets in Iran. In personality perspectives, dog owners are more disagreeable people and other pet owners are more emotionally stable ones.

Fertility control is important for population management of owned and unowned cats, provides health benefits at the individual level and can reduce unwanted sexually dimorphic behaviors such as roaming, aggression, spraying and calling. This article reviews the available evidence regarding European and American veterinarian, owner and pedigree cat breeder attitudes toward both surgical sterilization and non-surgical fertility control. It additionally presents new data on veterinarians' and pedigree cat breeders' use of, and attitudes toward, alternative modalities of fertility control. Within the United States and Europe, the proportion of cats reported to be sterilized varies widely. Published estimates range from 27-93% for owned cats and 2-5% for cats trapped as part of a trap-neuter-return (TNR) program. In some regions and populations of cats, non-surgical fertility control is also used. Social context, cultural norms, individual preferences, economic considerations, legislation and professional organizations may all influence fertility control decisions for cats. Particularly in Europe, a limited number of non-surgical temporary contraceptives are available for cats; these include products with regulatory approval for cats as well as some used 'off label'. Non-surgical methods remove the risk of complications related to surgery and offer potential to treat more animals in less time and at lower cost; they may also appeal to pedigree cat breeders seeking temporary contraception. However, concerns over efficacy, delivery methods, target species safety, duration and side effects exist with current non-surgical options. Research is under way to develop new methods to control fertility in cats without surgery. US and European veterinarians place high value on three perceived benefits of surgical sterilization: permanence, behavioral benefits and health benefits. Non-surgical options will likely need to share these benefits to be widely accepted by the veterinary

Dau, G.J.

1988-01-01

A survey was conducted to evaluate the utilities' perspective of the success of efforts of the Electric Power Research Institute (EPRI) and owner groups for the development and implementation of advanced technology. The source of the advanced technology was the result of a joint effort between EPRI and two utility owner groups. The former performs generic research and development (R and D) on behalf of its members drawn from the US electric utility industry. Owner groups are short-term associations of a group of utilities, all confronted with the same problem. Management implications for both EPRI and the utilities are drawn from the results and are summarized. They include recognition that EPRI's reputation for objectivity is an important asset that must be protected. Other implications include assessments of the merits and options for building better utility/NRC relations and strengthening the utility/EPRI relationship. Addressing the implications does not hinge on any major new development. Rather, it depends on EPRI and utility management making the commitment to support efforts to increase the intensity of communication on the baseline program. The resources needed are mainly provision of adequate staff time and attendant travel expenses

The characteristics of the human-animal bond may be influenced by both owner-related and dog-related factors. A study was designed to explore the existence of different dog ownership patterns and their related factors. We created an on line questionnaire that included demographic questions about the dog and the owner, a Spanish version of the Monash Dog Owner Relationship Scale (MDORS) and a validated measure of satisfaction with life (Cantril’s ladder). We collected 1140 valid responses from adult dog owners, who were recruited using the client databases of Spanish veterinary practices. We explored the presence of groups within the population using Principal Components Analysis (PCA) of the MDORS variables combined with Hierarchical Cluster Analysis (HCA). Two groups were found; Group I having a higher level of emotional involvement with their dogs compared with Group II. Binary logistic regression was used to explore demographic factors that influenced group membership. Four variables were significantly associated with membership of Group I (pdog-ownership may be present within a population of owner-dog dyads, and that certain owner characteristics are associated with the type of owner-dog relationship. Future research could apply a similar approach to different types of sample population in order to identify specific patterns of dog-ownership. PMID:28033397

Commercial nuclear power plants in this country can be owned by a number of separate entities, each with varying ownership proportions. Each of these owners may, in turn, have a parent/subsidiary relationship to other companies. In addition, the operator of the plant may be a different entity as well. This report provides a compilation on the owners/operators for all commercial power reactors in the United States. While the utility industry is currently experiencing changes in organizational structure which may affect nuclear plant ownership, the data in this report is current as of July 1996. The report is divided into sections representing different aspects of nuclear plant ownership.

The aim of this article is to assess the role played by both individual and contextual factors in reducing the manager's levels of stress and strain within the workplace setting. This article also highlights the manager's locus of control (LOC) as an internal factor and emphasizes the social support variable as a contextual factor. We use a sample of 332 respondents belonging to Spanish manufacturing and services firms and a structural equation modeling technique (partial least squares path modeling). The results reveal that there are significant differences between managers and owners about stress-strain relationship. The study provides support for the literature on stress management, which emphasizes the importance of a LOC and social support in influencing stress and strain between managers and owners.

Integrated hydrogen control solutions for severe accidents using passive autocatalytic recombiners

International Nuclear Information System (INIS)

Bauer, M.; Tietsch, W.; Sabate Farnos, R.

2012-01-01

In a severe accident or a beyond-design-basis-accident, the reaction of water with zirconium alloy cladding, radiolysis of water, corium-concrete reactions and other corrosion phenomena generate hydrogen (H2). The detonation of this H2 in containment or in auxiliary buildings can result in damage to structures or loss of containment integrity. Identifying the generation and special distribution of hydrogen and controlling its concentration with Passive Autocatalytic Recombiners (PARs) solves this concern. Westinghouse's approach for hydrogen management starts by defining the quantities and transport/distribution of H 2 in-containment and out of containment with analysis tools such as MAAP, MELCOR, GASFLOW or FATE. Based on the results of these analyses, an optimized H2 Control Strategy is proposed in terms of number and location of PARs, and efficient integration with other H 2 management devices like e.g. existing igniters, H 2 monitors, etc.

"Who's been a good dog?" - Owner perceptions and motivations for treat giving.

Complex relationships commonly exist between owners and their companion animals, particularly around feeding behaviour with an owner's affection or love for their animal most pronounced through the provision of food. It is notable that the pet food market is experiencing strong year-on-year growth in sales of dog and cat treats. Recognising the impact of treat giving in pet nutrition, the objective of the study was to investigate owner attitudes and motivations towards feeding treats (shop bought and other) to their dogs. A researcher-mediated questionnaire consisting of both quantitative and qualitative questions was used to interview dog owners (n=280) at two locations: an out-of-town retail park and a country park in the East Midlands. Owners almost unanimously viewed the word 'treat' within a nutritional context, as opposed to a new toy or other pleasure. The majority (96%) of owners interviewed reported feeding treats to their dog, with 69% feeding shop-bought treats on a daily basis. A wide range of treats was reportedly given by owners and the majority of owners interviewed fed multiple treat types. No association was found between owner age and frequency of shop-bought treats fed (P=0.659) nor between owner age and frequency of food given to the dog from the owner's plate (P=0.083). A wide range of foods which would not be considered balanced for the animal's nutritional requirements was viewed as a treat by some dog owners. A range of positive and negative views around the feeding of treats were expressed by dog owners, with some citing beneficial effects while others were clearly aware of the association between treat feeding and potential weight gain/obesity. Owner views included themes around positive reinforcement and responsibility but also reflected relational aspects of the human-animal bond. The results of the study show that treat giving is commonplace in feeding regimes and that treats are embedded in the feeding behaviour of many dog owners

Control Scheme Formulation for the Production of Hydrogen on Demand to Feed an Internal Combustion Engine

Directory of Open Access Journals (Sweden)

Jarniel García Morales

2016-12-01

Full Text Available In this work, a control strategy is presented to produce hydrogen on demand to feed an internal combustion (IC engine. For this purpose, the modeling of the IC engine fueled by gasoline blended with 10 % v/v of anhydrous ethanol (E10 and hydrogen as an additive is developed. It is considered that the hydrogen gas is produced according to the IC engine demand, and that the hydrogen gas is obtained by an alkaline electrolyzer. The gasoline–ethanol blend added into the combustion chamber is determined according to the stoichiometric ratio and the production of hydrogen gas is regulated by a proportional and integral controller (P.I.. The controller reference is varying according to the mass flow air induced into the cylinder, in order to ensure an adequate production of hydrogen gas for any operating condition of the IC engine. The main contribution of this work is the control scheme developed, through simulation, in order to produce hydrogen on demand for any operating point of an internal combustion engine fueled by an E10 blend. The simulation results showed that the use of hydrogen gas as an additive in an E10 blend decreases the E10 fuel consumption 23 % on average, and the thermal efficiency is increased approximately 2.13 % , without brake power loss in the IC engine.

It has been suggested that the way in which owners interact with their dogs can largely vary and influence the dog-owner bond, but very few objective studies, so far, have addressed how the owner interacts with the dog. The goal of the present study was to record dog owners' interaction styles by means of objective observation and coding. The experiment included eight standardized situations in which owners of pet dogs were asked to perform specific tasks including both positive (i.e. playing, teaching a new task, showing a preference towards an object in a food searching task, greeting after separation) and potentially distressing tasks (i.e. physical restriction during DNA sampling, putting a T-shirt onto the dog, giving basic obedience commands while the dog was distracted). The video recordings were coded off-line using a specifically designed coding scheme including scores for communication, social support, warmth, enthusiasm, and play style, as well as frequency of behaviors like petting, praising, commands, and attention sounds. Exploratory Factor Analysis of the 20 variables measured revealed 3 factors, labeled as Owner Warmth, Owner Social Support, and Owner Control, which can be viewed as analogues to parenting style dimensions. The experimental procedure introduced here represents the first standardized measure of interaction styles of dog owners. The methodology presented here is a useful tool to investigate individual variation in the interaction style of pet dog owners that can be used to explain differences in the dog-human relationship, dogs' behavioral outcomes, and dogs stress coping strategies, all crucial elements both from a theoretical and applied point of view.

In recent years there has been an increasing demand to reduce and control the amount of dissolved gases in steel. Hydrogen and nitrogen are two of the most important gases which when dissolved in liquid steel affect its properties significantly. Several steelmaking additions have been investigated in this research for their effect on the hydrogen and nitrogen content of steels. It has been established that calcium hydroxide (hydrated lime) acts as a source of hydrogen. Carburizers, such as metallurgical coke, were found to result in no hydrogen pickup when added to liquid steel. Addition of petroleum coke, on the other hand, increased the hydrogen content of liquid steel. Ferroalloy such as medium carbon ferromanganese when added to the liquid iron was found to increase its nitrogen content, the increase being proportional to the amount of ferroalloy added. Similarly, addition of pitch coke, which had a significant nitrogen impurity, increased the nitrogen content of liquid iron. A mathematical model was developed to quantify the absorption of nitrogen and hydrogen from the air bubbles entrained during tapping of liquid steel. During the bottom stirring of liquid metal in a ladle, the inert gas escaping from the top displaces the slag layer and often forms an open eye. The absorption of atmospheric nitrogen through the spout eye was estimated for different slag thickness and gas flow rate. The ultimate goal of this research was to develop a comprehensive set of equations which could predict the nitrogen and hydrogen pickup from their various sources. Estimates of hydrogen and nitrogen pickup during the steel transfer operations such as tapping and ladle stirring and the predicted pickup from steelmaking additions were integrated into empirical equations. The comprehensive model is designed to predict the gas pickup under varying operating conditions such as the metal oxygen and sulfur content, the total tapping or stirring time, the stirring gas flow rate and the

In order to reduce oxygen impurity and hydrogen recycling, ECR discharge cleaning with hydrogen, glow discharge with helium, and titanium gettering have been applied. The ECR discharge cleaning was found to be effective in reducing oxygen impurities in ECRH discharges. However, it was not sufficiently effective to give a wide operational density range in NBI heated discharges. Titanium gettering is essential for this purpose, and controllable discharges have been achieved in the density range 1-10x10 19 m -3 , with discharge length more than 850 ms with the aid of titanium gettering. Both helium-glow discharge and Ti gettering are useful to control hydrogen recycling even with a stainless steel wall. (orig.)

Control of hydrogen concentration in reactor containment buildings by using passive catalytic recombiners

International Nuclear Information System (INIS)

Wolff, U.

1993-01-01

Severe accidents in nuclear power plants have the potential to generate hydrogen within the reactor containment building in concentrations likely to deflagrate or even detonate. This could endanger the containment integrity. Autocatalytic devices have been developed by the NIS company in Hanau, Germany, to control the hydrogen concentration within the containment. These devices have been tested by the Battelle Institute in Frankfurt, Germany, under conditions relevant to severe accidents. The catalytic device functions as required in a wide band of gas mixtures ranging from inerted conditions with low-hydrogen and/or low-oxygen concentrations up to detonable mixtures. The device starts up quickly, and has a high resistance against catalyst poisons including the effects of oil or cable fires. The device makes a strong contribution to gas mixing in the containment atmosphere. The paper summarizes the development work done and describes the final design of the device. Theoretical tools for analysis and prediction of catalyst performance in containment environments have been developed by the Battelle Institute and the Technical University of Munich. These tools have been verified and validated against experimental data. A phenomenological discussion of accident scenarios is used to explain the functional requirements for the autocatalytic devices in the control of hydrogen. Both the potential for and limitations of such devices for hydrogen control are discussed for large dry containments (PWRs) and for those which are originally inerted (BWRs)

Companion animals have established special relationships with humans, as demonstrated by many studies describing their abilities and bonds to communicate with humans. In this questionnaire-based study, we explored owners' views of pets in terms of their emotional and intellectual functions and their relationship with owners, and compared the results between cat owners and dog owners. We found that although both types of owners most often regarded their pets as "family members," this tendency was weaker in cat owners. Cat owners also scored significantly lower than dog owners for some emotions and intellect they thought their pets might have. Additionally, cat owners who regard their cats as family members tend to attribute "compassion" to their cats more strongly than cat owners who regard their pets as non-family. This study revealed that some aspects of cat owners' views of their pets differ from those of dog owners. These finding may help us to better understand our heterospecific companions and establish good relationships with them. Copyright © 2017 Elsevier B.V. All rights reserved.

A framework for evaluating hydrogen control and management

International Nuclear Information System (INIS)

Lee, Seung Dong; Suh, Kune Yul; Jae, Moosung

2003-01-01

The present paper presents a new framework for assessing accident management strategies using decision trees. The containment event tree (CET) model considers characteristics associated with the implementation of each strategy. It is constructed and quantified using data obtained from NUREG-1150, other probabilistic risk assessments, and the MAAP4 calculations. The proposed framework for evaluating hydrogen control strategies is based on the concept of a measure using a risk triplet. Ulchin units of nuclear power plants 3 and 4 are used as the reference plant. On the basis of best-estimate assessment, it is shown that it is beneficial to execute hydrogen igniters rather than to do nothing with respect to expected value of hydrogen concentration in the containment during an accident. The proposed approach is shown to be flexible in that it can be applied to various accident management strategies based on the timing of mitigation. The advantage of using the CET for assessing an accident management strategy lies with its capability for modeling both the positive and negative aspects associated with progression of the accident, which may in turn affect the containment failure mode

In our previous study, the quenching meshes have been proposed for the control of hydrogen combustion under nuclear severe accident. It has been investigated whether the method of installation of quenching mesh to prevent flame from propagating to the other compartment is proper or not. Schlieren photograph is used to visualize the propagation of flame between two compartments. Without the quenching mesh equipped between the compartments, it has been observed that the flame always propagates from a compartment to the other. The data on quencing distance of hydrogen premixed flames gotten in our previous study is alayzed to setup of optimum quenching mesh, too. Such experimental results establish that the quenching meshes proposed for the control of hydrogen combustion are resonably available

To achieve statistical significance in medical research, biological or data samples from several bio- or databanks often need to be complemented by those of other institutions. For that purpose, IT-based search services have been established to locate datasets matching a given set of criteria in databases distributed across several institutions. However, previous approaches require data owners to disclose information about their samples, raising a barrier for their participation in the network. To devise a method to search distributed databases for datasets matching a given set of criteria while fully maintaining their owner's data sovereignty. As a modification to traditional federated search services, we propose the decentral search, which allows the data owner a high degree of control. Relevant data are loaded into local bridgeheads, each under their owner's sovereignty. Researchers can formulate criteria sets along with a project proposal using a central search broker, which then notifies the bridgeheads. The criteria are, however, treated as an inquiry rather than a query: Instead of responding with results, bridgeheads notify their owner and wait for his/her decision regarding whether and what to answer based on the criteria set, the matching datasets and the specific project proposal. Without the owner's explicit consent, no data leaves his/her institution. The decentral search has been deployed in one of the six German Centers for Health Research, comprised of eleven university hospitals. In the process, compliance with German data protection regulations has been confirmed. The decentral search also marks the centerpiece of an open source registry software toolbox aiming to build a national registry of rare diseases in Germany. While the sacrifice of real-time answers impairs some use-cases, it leads to several beneficial side effects: improved data protection due to data parsimony, tolerance for incomplete data schema mappings and flexibility with regard

Successful veterinary treatment of animals requires owner adherence with a prescribed treatment plan. The aim of our study was to evaluate and compare the level of adherence of the owners of patients presented for behavioural, cardiological, urological, and oncological problems. At the end of the first examination, each owner completed a questionnaire. Then, the owners were called four times to fill out another questionnaire over the phone. With regard to the first questionnaire, statistically significant data concern behavioral medicine and cardiology. In the first area the owner's worry decreases during the follow-up and the number of owners who would give away the animal increases. In cardiology, owners who think that the pathology harms their animal's quality of life decreased significantly over time. With regard to the 9 additional follow-up questions, in behavioural medicine and urology the owner's discomfort resulting from the animal's pathology significantly decreases over time. Assessment of adherence appears to be an optimal instrument in identifying the positive factors and the difficulties encountered by owners during the application of a treatment protocol.

2011-12-01

The overall aim of this study was to examine the nature of the relationship between dog-ownership and canine obesity, explored in two cohorts of overweight/obese or non-overweight dogs (n=125). This paper concentrates on the owners' perception of dog weight. A researcher-mediated questionnaire was used to collect data from dog owners attending a small veterinary practice. Interviewees (n=121) were asked qualitative and quantitative questions, designed to examine the owners' views of their relationship with their dogs. Although a high proportion of owners claimed to have discussed the dog's weight with their veterinarian, some discrepancies were apparent between owner perception of animal weight and the veterinarian's evaluation of body condition score. Owner disagreement was significantly greater for the veterinarian-defined overweight dogs (P=0·005). Owners often provide personal narratives to account for their dog's weight status. This study confirms the important role of the vet in providing information about the issue of dog weight but also suggests that providing verbal information is sometimes insufficient. The study also indicates the potential value of qualitative research methods to further understand client perception of complex animal care issues and highlights the need for further in-depth research. © 2011 British Small Animal Veterinary Association.

Even though the event at Three Mile Island was a bleak moment in the history of nuclear power, many advances in the nuclear industry have evolved as a result. One such advancement involves the establishment of NSSS Vendor Owners Groups. These groups were organized on a voluntary basis with nearly all utilities participating. The main purpose was to achieve mutual benefit, both technical and financial, through joint engineering and plant operation programs. This paper focuses on the Westinghouse Owners Group, which is commonly referred to as the WOG, and how it has benefited and could further benefit utility training. The paper consists of three sections. The first section provides an overview of the WOG structure and how it functions. The second section focuses on the major accomplishments of the WOG with emphasis on the development of the Emergency Response Guidelines (ERGs). The third section provides some recommendations as to how utility training departments can better utilize their owners groups

This qualitative study used a grounded theory methodology to analyze life-story interviews obtained from 10 family business owners regarding their experiences in their businesses with the goal of understanding the complexities of family business succession. The grounded theory that emerged from this study is best understood as a potential web of constraints that can bear on the succession process. Coding of these interviews revealed four key influences, which seem to have the potential to facilitate or constrain the family business owner's approach to succession. Influence 1, "The business within," captures intrapsychic dynamics of differentiation and control. Influence 2, "The marriage," addresses how traditional gender roles shape succession. Influence 3, "The adult children," examines the role of having a natural (accidental, organic, passively groomed) successor. Influence 4, "The vision of retirement," captures the impact of owners' notions of life post-succession. Family therapists frequently encounter family systems in which the family business is facing succession. Even if succession is not the presenting problem, and even if the business owner is in the indirect (rather than direct) system, this research reminds clinicians of the importance of the family's story about the family business. Therefore, clinical implications and recommendations are included. 2011 © FPI, Inc.

2018-07-01

To quantify the proportion of current US gun owners who are new to owning firearms and compare new versus long-standing gun owners with respect to their firearms and firearm-related behaviors. We performed a cross-sectional analysis of a nationally representative probability-based online survey conducted in 2015 in the United States. We defined new gun owners as current firearm owners who acquired all of their firearms within the past 5 years, but who lived in a home without a gun at some time over the past 5 years. We defined long-standing firearm owners as all other current gun owners. New gun owners represented 10% of all current US adult gun owners. In addition to being younger than long-standing gun owners, new gun owners were more likely to be liberal, own fewer guns, own handguns, own guns only for protection, and store guns in a safe manner. Gun ownership is dynamic, with approximately 1 million Americans becoming new gun owners each year. Public Health Implications. Clinical guidelines should be updated to explicitly endorse re-evaluating household firearm status at regular intervals.

To characterize the process by which people who find lost pets search for the owners. Cross-sectional study. Sample Population-188 individuals who found a lost pet in Dayton, Ohio, between March 1 and June 30, 2006. Procedures-Potential participants were identified as a result of contact with a local animal agency or placement of an advertisement in the local newspaper. A telephone survey was conducted to identify methods participants used to find the pets' owners. 156 of 188 (83%) individuals completed the survey. Fifty-nine of the 156 (38%) pets were reunited with their owners; median time to reunification was 2 days (range, 0.5 to 45 days). Only 1 (3%) cat owner was found, compared with 58 (46%) dog owners. Pet owners were found as a result of information provided by an animal agency (25%), placement of a newspaper advertisement (24%), walking the neighborhood (19%), signs in the neighborhood (15%), information on a pet tag (10%), and other methods (7%). Most finders (87%) considered it extremely important to find the owner, yet only 13 (8%) initially surrendered the found pet to an animal agency. The primary reason people did not surrender found pets was fear of euthanasia (57%). Only 97 (62%) individuals were aware they could run a found-pet advertisement in the newspaper at no charge, and only 1 person who was unaware of the no-charge policy placed an advertisement. Veterinarians and shelters can help educate people who find lost pets about methods to search for the pets' owners.

Controlling hydrogenation activity and selectivity of bimetallic surfaces and catalysts

Science.gov (United States)

Murillo, Luis E.

Studies of bimetallic systems are of great interest in catalysis due to the novel properties that they often show in comparison with the parent metals. The goals of this dissertation are: (1) to expand the studies of self-hydrogenation and hydrogenation reactions on bimetallic surfaces under ultra high vacuum conditions (UHV) using different hydrocarbon as probe molecules; (2) to attempt to correlate the surface science findings with supported catalyst studies under more realistic conditions; and (3) to investigate the competitive hydrogenation of C=C versus C=O bonds on Pt(111) modified by different 3d transition metals. Hydrogenation studies using temperature programmed desorption (TPD) on Ni/Pt(111) bimetallic surfaces have demonstrated an enhancement in the low temperature hydrogenation activity relative to that of clean Pt(111). This novel hydrogenation pathway can be achieved under UHV conditions by controlling the structures of the bimetallic surfaces. A low temperature hydrogenation activity of 1-hexene and 1-butene has been observed on a Pt-Ni-Pt(111) subsurface structure, where Ni atoms are mainly present on the second layer of the Pt(111) single crystal. These results are in agreement with previous studies of self-hydrogenation and hydrogenation of cyclohexene. However, a much higher dehydrogenation activity is observed in the reaction of cyclohexene to produce benzene, demonstrating that the hydrocarbon structure has an effect on the reaction pathways. On the other hand, self-hydrogenation of 1-butene is not observed on the Pt-Ni-Pt(111) surface, indicating that the chain length (or molecular weight) has a significant effect on the selfhydrogenation activity. The gas phase reaction of cyclohexene on Ni/Pt supported on alumina catalysts has also shown a higher self-hydrogenation activity in comparison with the same reaction performed on supported monometallic catalysts. The effects of metal loading and impregnation sequence of the metal precursors are

Control of accidental releases of hydrogen selenide in vented storage cabinets

Fthenakis, V. M.; Moskowitz, P. D.; Sproull, R. D.

1988-07-01

Highly toxic hydrogen selenide and hydrogen sulfide gases are used in the production of copper-indium-diselenide photovoltaic cells by reactive sputtering. In the event of an accident, these gases may be released to the atmosphere and pose hazards to public and occupational safety and health. This paper outlines an approach for designing systems for the control of these releases given the uncertainty in release conditions and lack of data on the chemical systems involved. Accidental releases of these gases in storage cabinets can be controlled by either a venturi and packed-bed scrubber and carbon adsorption bed, or containment scrubbing equipment followed by carbon adsorption. These systems can effectively reduce toxic gas emissions to levels needed to protect public health. The costs of these controls (˜0.012/Wp) are samll in comparison with current (˜6/Wp) and projected (˜I/Wp) production costs.

Chromium gettering has been proven to be a trouble-free and efficient method of surface pumping in tokamaks. The impurity control capabilities are excellent and comparable to that of titanium. The hydrogen uptake is reduced to monolayer quantities on the surface. The expansion of the operating space is similar to that seen with titanium without the disadvantage of strongly increased hydrogen fluxes. Possible applications of chromium gettering are: impurity control in contemporary tokamaks; surface pumping in short pulse DT-burning devices to minimize tritium inventory, and wall conditioning of future large machines prior to operation

Kaneko, Megumi

2006-04-01

A multi-method approach was used to examine whether and how companion animals (CA) affect subjective well-being and social networks of Japanese people. In Study 1, a mail survey with a probability sample of 1250 Japanese adults over 40 years old showed that (1) female owners' attachment to CA negatively correlated with subjective well-being, and (2) although younger (under 65) CA owners had more close friends than non-owners, this tendency was reversed for those over 65. In Study 2, in-depth interviews with 27 adults showed that (1) female CA owners reported lower subjective well-being than non-owners, (2) although CA owners were generally successful in interacting with strangers through CA-related behaviors such as dog-walking, those relationships were unlikely to become close, and (3) in contrast to the owners' tendency to portray themselves in positive ways, most non-owners described CA owners negatively, such as being lonely or bad-mannered. Based on the present findings, which sharply contradict those of previous studies in the western societies, future issues are discussed.

In the aftermath of the incident at Three Mile Island Unit 2 (TMI-2), a new and different treatment of the Light Water Reactor (LWR) risks is needed for public safety because of the specific events involving hydrogen generation, transport, and behavior following the core damage. Hydrogen behavior in closed environments such as the TMI-2 containment building is a complex phenomenon that is not fully understood. Hence, an engineering approach is presented for prevention of loss of life, equipment, and environment in case of a large hydrogen generation in an LWR. A six-level defense strategy is described that minimizes the possibility of ignition of released hydrogen gas and otherwise mitigates the consequences of hydrogen release. Guidance is given to reactor manufacturers, utility companies, regulatory agencies, and research organizations committed to reducing risk factors and insuring safety of life, equipment, and environment

Fuzzy logic control for selective hydrogenation of acetylene in ethylene rich streams using visual basic

International Nuclear Information System (INIS)

Malik, S.R.; Suleman, H.; Khan, J.R.

2010-01-01

Presence of acetylene is technically disadvantageous in the ethylene rich gas streams from steam crackers. Acetylene tends to polymerize and inactivates the transition metal catalysts, forming highly explosive compounds. The acetylene content has to be selectively reduced to less than one part per million for such streams. The acetylene hydrogenation unit requires stringent control parameters and needs specialized process control techniques for its operation. This study is concerned with application of Fuzzy Logic Control to manipulate and control the process plant with higher precision and greater simplicity. The control program has been written in visual Basic and entails all major scenarios of work modes for successful hydrogenation of Acetylene. (author)

This qualitative research explored the relationship between dog ownership and dog-related, social environmental and physical environmental factors associated with walking with a dog. Seven focus groups with dog owners (n=51) were conducted. A pre-determined discussion guide was used and transcripts were analysed as group data, using content analysis to identify common themes. Many of the physical environmental barriers and facilitators that influenced dog owners to walk were similar to those found in the literature for general walking. However, a number of key motivators for walking, specific to dog owners, were identified. Dog owners reported that their dog was a strong source of motivation, companionship and social support that encouraged them to walk with their dog. The availability and accessibility of public open space (POS) for dogs and the provision of dog-related infrastructure within POS were also important environmental factors that affected whether owners walked with their dog. Results from this qualitative study were used to develop the Dogs and Physical Activity (DAPA) tool which is now being used to measure the walking behaviour of dog owners.

Full Text Available Successful veterinary treatment of animals requires owner adherence with a prescribed treatment plan. The aim of our study was to evaluate and compare the level of adherence of the owners of patients presented for behavioural, cardiological, urological, and oncological problems. At the end of the first examination, each owner completed a questionnaire. Then, the owners were called four times to fill out another questionnaire over the phone. With regard to the first questionnaire, statistically significant data concern behavioral medicine and cardiology. In the first area the owner’s worry decreases during the follow-up and the number of owners who would give away the animal increases. In cardiology, owners who think that the pathology harms their animal’s quality of life decreased significantly over time. With regard to the 9 additional follow-up questions, in behavioural medicine and urology the owner’s discomfort resulting from the animal’s pathology significantly decreases over time. Assessment of adherence appears to be an optimal instrument in identifying the positive factors and the difficulties encountered by owners during the application of a treatment protocol.

Full Text Available The ability to identify opportunities is the force behind thousands of small and medium enterprises, contributing to the improvement of social and economic performance of a country. The choice between starting an independent business or becoming franchisee seems to depend on different behaviors and attitudes of the entrepreneur. This research aims verify, based on entrepreneurial behavioral characteristics and the theory of planned behavior, whether there are differences in the degree of entrepreneurial attitude of franchisees and independent business owners, especially the food service industry. The issue as to possibility finding different attitudes in this study originated from assumedly less entrepreneurial characteristics of the franchisee, such as greater security and reduced innovation. As a theoretical basis, we dug into the concepts of entrepreneurship, entrepreneur and franchise, besides attitude and planned behavior. To data collect data we used the Instrument of Measure Entrepreneurial Attitude (IMAE proposed by Lopes and Souza Jr. (2005. The study was conducted with thirty occupants of the position of owner, main manager or co-owner of small and medium-sized food enterprises, in the city of Uberlândia, Brazil. Fifteen of them were franchisees and fifteen were independent business owners. Results indicated that, contrary to expectations, the entrepreneurial attitude of franchisees is higher. The most determinant factor in the entrepreneurial attitude differences observed in this study seems to be time in business.

Owners consulting the internet before venturing into a veterinary practice is a real issue in today's technological age, but how often do vets step into the owner's shoes and try to understand why they do so? On the farm, what are the motivations of the farmer, and are these being listened to by the vet? These were just some of the questions raised in a session at the BVA Congress during the London Vet Show last week. Georgina Mills reports. British Veterinary Association.

My owner, right or wrong: the effect of familiarity on the domestic dog's behavior in a food-choice task.

Dogs are strongly influenced by human behavior, and they readily form bonds with specific humans. Yet these lines of inquiry are not often combined. The goal of this study was to investigate whether such bonds would play a role in how dogs behave in response to human signals. Using various types of signals, we compared dogs' use of information from a familiar human (their owner) versus an unfamiliar human when choosing between two food containers. In some conditions, the owner indicated a container that gave food and a stranger indicated a container that did not; in other conditions, this was reversed. Dogs more often chose the container indicated by or nearest to their owner, even when this container never yielded a food reward. In two conditions, dogs chose at chance: a control condition in which both pointers were strangers and a condition in which the owner and stranger sat reading books and provided no social signal. This is the first study to directly compare owners to strangers in a single food-choice situation. Our results suggest that dogs make decisions by attending preferentially to social signals from humans with whom they have become familiar.

North-Karelian forest owners' attitude to nature-emulating forestry work methods

Jouhiaho, A.

1999-01-01

The TTS-Institute conducted a mail-questionnaire study of forest owners' opinions in the Province of North Karelia (Pohjois-Karjala) concerning work methods as applied in silviculture and logging. In addition, the study looked into the matter of the forest owners' willingness to pay for the implementation of nature-emulating silviculture and logging. The response percentage was 57 % with 344 forest owners responding to the questionnaire. The majority of the forest owners understood nature-emulating silviculture and logging as worthwhile objectives and as actions aimed at economically advantageous outcomes. Nature-emulating work methods involve the use of method emulating the natural development dynamics of forest ecosystems and causing minimum disturbance to the ecosystem. The term 'nature-emulating' was also seen to include forest treatment with awareness of landscape management viewpoints. Less than half of the forest owners were willing to pay for the implementation of nature-emulating silviculture and logging. Of those willing to pay, half were prepared to pay an extra 6 - 10 % for sivicultural and 1 - 5 % for logging on top of the costs. (orig.)

Controlled Hydrogen Fleet and Infrastructure Demonstration Project

2010-03-31

This program was undertaken in response to the US Department of Energy Solicitation DE-PS30-03GO93010, resulting in this Cooperative Agreement with the Ford Motor Company and BP to demonstrate and evaluate hydrogen fuel cell vehicles and required fueling infrastructure. Ford initially placed 18 hydrogen fuel cell vehicles (FCV) in three geographic regions of the US (Sacramento, CA; Orlando, FL; and southeast Michigan). Subsequently, 8 advanced technology vehicles were developed and evaluated by the Ford engineering team in Michigan. BP is Ford's principal partner and co-applicant on this project and provided the hydrogen infrastructure to support the fuel cell vehicles. BP ultimately provided three new fueling stations. The Ford-BP program consists of two overlapping phases. The deliverables of this project, combined with those of other industry consortia, are to be used to provide critical input to hydrogen economy commercialization decisions by 2015. The program's goal is to support industry efforts of the US President's Hydrogen Fuel Initiative in developing a path to a hydrogen economy. This program was designed to seek complete systems solutions to address hydrogen infrastructure and vehicle development, and possible synergies between hydrogen fuel electricity generation and transportation applications. This project, in support of that national goal, was designed to gain real world experience with Hydrogen powered Fuel Cell Vehicles (H2FCV) 'on the road' used in everyday activities, and further, to begin the development of the required supporting H2 infrastructure. Implementation of a new hydrogen vehicle technology is, as expected, complex because of the need for parallel introduction of a viable, available fuel delivery system and sufficient numbers of vehicles to buy fuel to justify expansion of the fueling infrastructure. Viability of the fuel structure means widespread, affordable hydrogen which can return a reasonable profit to

The main objective of this study was to evaluate the prevalence of canine obesity and obesity-related metabolic dysfunction (ORMD) in the obesogenic area in Spain. The prevalence of overweight/obesity among owners of obese pets was also evaluated. In the sample population studied (93 client-owned dogs), 40.9% of dogs presented obesity (body condition score 7-9/9), 40.9% of dogs presented hypertension, 20.4% of dogs presented fasting hypertriglyceridemia, 20.4% fasting hypercholesterolemia, and 5.4% of dogs presented fasting hyperglycemia. The overall prevalence of ORMD was of 22.6%. Seventy-eight percent of overweight/obese owners had overweight/obese dogs ( P  canine obesity and ORMD was shown to be elevated and related to the presence of overweight/obesity in owners. All dogs with ORMD were owned by overweight/obese persons. These results provide new inputs for future studies highlighting the relationship between owner and pet obesity and indicating the need of further efforts to control and reduce obesity prevalence in both.

Hydrogen water chemistry for BWRs: A status report on the EPRI development program

International Nuclear Information System (INIS)

Jones, R.L.; Nelson, J.L.

1990-01-01

Many BWRs have experienced extensive intergranular stress corrosion cracking (IGSCC) in their austenitic stainless steel coolant system piping, resulting in serious adverse impacts on plant capacity factors, O and M costs, and personnel radiation exposures. A major research program to provide remedies for BWR pipe cracking was co-funded by EPRI, GE, and the BWR Owners Group for IGSCC Research between 1979 and 1988. Results from this program show that the likelihood of IGSCC depends on reactor water chemistry (particularly on the concentrations of ionic impurities and oxidizing radiolysis products) as well as on material condition and the level of tensile stress. Tests have demonstrated that the concentration of oxidizing radiolysis products in the recirculating water of a BWR can be reduced substantially by injecting hydrogen into the feedwater. Recent plant data show that the use of hydrogen injection can reduce the rate of IGSCC to insignificant levels if the concentration of ionic impurities in the reactor water is kept sufficiently low. This approach to the control of BWR pipe cracking is called hydrogen water chemistry (HWC). This paper presents a review of the results of EPRI's HWC development program from 1980 to the present. In addition, plans for additional work to investigate the feasibility of adapting HWC to protect the BWR vessel and major internal components from potential stress corrosion cracking problems are summarized.

2009-04-01

Although research indicates that second-hand smoke (SHS) harms both human and animal health, data on the percentage of pet owners who smoke or allow smoking in their homes are not readily available. To investigate pet owners' smoking behaviour and policies on smoking in their homes, and the potential for educational interventions to motivate change in pet owners' smoking behaviour. A web-based survey was used with 3293 adult pet owners. The main outcome measures were smoking behaviour of pet owners and their cohabitants; policies on smoking in pet owners' homes; and impact of information about the dangers of pet exposure to SHS on pet owners' smoking intentions. Of respondents, 21% were current smokers and 27% of participants lived with at least one smoker. Pet owners who smoke reported that information on the dangers of pet exposure to SHS would motivate them to try to quit smoking (28.4%) and ask the people with whom they live to quit smoking (8.7%) or not to smoke indoors (14.2%). Moreover, non-smoking pet owners who live with smokers said that they would ask the people with whom they live to quit (16.4%) or not smoke indoors (24.2%) if given this information. About 40% of current smokers and 24% of non-smokers living with smokers indicated that they would be interested in receiving information on smoking, quitting, or SHS. Educational campaigns informing pet owners of the risks of SHS exposure for pets could motivate some owners to quit smoking. It could also motivate these owners and non-smoking owners who cohabit with smokers make their homes smoke-free.

Control of malodorous hydrogen sulfide compounds using microbial fuel cell.

Eaktasang, Numfon; Min, Hyeong-Sik; Kang, Christina; Kim, Han S

2013-10-01

In this study, a microbial fuel cell (MFC) was used to control malodorous hydrogen sulfide compounds generated from domestic wastewaters. The electricity production demonstrated a distinct pattern of a two-step increase during 170 h of system run: the first maximum current density was 118.6 ± 7.2 mA m⁻² followed by a rebound of current density increase, reaching the second maximum of 176.8 ± 9.4 mA m⁻². The behaviors of the redox potential and the sulfate level in the anode compartment indicated that the microbial production of hydrogen sulfide compounds was suppressed in the first stage, and the hydrogen sulfide compounds generated from the system were removed effectively as a result of their electrochemical oxidation, which contributed to the additional electricity production in the second stage. This was also directly supported by sulfur deposits formed on the anode surface, which was confirmed by analyses on those solids using a scanning electron microscope equipped with energy dispersive X-ray spectroscopy as well as an elemental analyzer. To this end, the overall reduction efficiencies for HS⁻ and H₂S(g) were as high as 67.5 and 96.4 %, respectively. The correlations among current density, redox potential, and sulfate level supported the idea that the electricity signal generated in the MFC can be utilized as a potential indicator of malodor control for the domestic wastewater system.

Kotrschal, Kurt; Schöberl, Iris; Bauer, Barbara; Thibeaut, Anne-Marie; Wedl, Manuela

2009-07-01

In the paper we investigate how owner personality, attitude and gender influence dog behavior, dyadic practical functionality and the level of dog salivary cortisol. In three meetings, 12 female and 10 male owners of male dogs answered questionnaires including the Neo-FFI human personality inventory. Their dyadic behavior was video-taped in a number of test situations, and saliva samples were collected. Owners who scored highly in neuroticism (Neo-FFI dimension one) viewed their dogs as social supporters and spent much time with them. Their dogs had low baseline cortisol levels, but such dyads were less successful in the operational task. Owners who scored highly in extroversion (Neo-FFI dimension two) appreciated shared activities with their dogs which had relatively high baseline cortisol values. Dogs that had female owners were less sociable-active (dog personality axis 1) than dogs that had male owners. Therefore, it appears that owner gender and personality influences dyadic interaction style, dog behavior and dyadic practical functionality.

Attachment Style Is Related to Quality of Life for Assistance Dog Owners.

White, Naomi; Mills, Daniel; Hall, Sophie

2017-06-19

Attachment styles have been shown to affect quality of life. Growing interest in the value of companion animals highlights that owning a dog can also affect quality of life, yet little research has explored the role of the attachment bond in affecting the relationship between dog ownership and quality of life. Given that the impact of dog ownership on quality of life may be greater for assistance dog owners than pet dog owners, we explored how anxious attachment and avoidance attachment styles to an assistance dog affected owner quality of life ( n = 73). Regression analysis revealed that higher anxious attachment to the dog predicted enhanced quality of life. It is suggested that the unique, interdependent relationship between an individual and their assistance dog may mean that an anxious attachment style is not necessarily detrimental. Feelings that indicate attachment insecurity in other relationships may reflect more positive aspects of the assistance dog owner relationship, such as the level of support that the dog provides its owner.

Lit, Lisa; Schweitzer, Julie B; Oberbauer, Anita M

2010-07-01

Dog owners were surveyed for observations of social behaviors in their dogs, using questions adapted from the human Autism Diagnostic Observation Schedule (ADOS) pre-verbal module. Using 939 responses for purebred and mixed-breed dogs, three factors were identified: initiation of reciprocal social behaviors (INIT), response to social interactions (RSPNS), and communication (COMM). There were small or no effects of sex, age, breed group or training. For six breeds with more than 35 responses (Border Collie, Rough Collie, German Shepherd, Golden Retriever, Labrador Retriever, Standard Poodle), the behaviors eye contact with humans, enjoyment in interactions with human interaction, and name recognition demonstrated little variability across breeds, while asking for objects, giving/showing objects to humans, and attempts to direct humans' attention showed higher variability across these breeds. Breeds with genetically similar backgrounds had similar response distributions for owner reports of dog response to pointing. When considering these breeds according to the broad categories of "herders" and "retrievers," owners reported that the "herders" used more eye contact and vocalization, while the "retrievers" used more body contact. Information regarding social cognitive abilities in dogs provided by owner report suggest that there is variability across many social cognitive abilities in dogs and offers direction for further experimental investigations.

1997-03-01

The Workshop on the Implementation of Hydrogen Mitigation Techniques was held in Winnipeg, Manitoba,Canada from 1996 May 13 to 15. It was organized in collaboration with the Whiteshell Laboratories of Atomic Energy of Canada Limited (AECL), Ontario Hydro and the CANDU Owner's Group (COG). Sixty-five experts from twelve OECD Member countries and the Russian Federation attended the meeting. Papers presented in the sessions included topics: accident management and analysis, relevant aspects of hydrogen production, distribution and mixing, engineering, technology, possible side-effects consequences and new designs. The objectives of the Workshop were the following: to establish the state of the art of hydrogen mitigation techniques, with emphasis on igniters and catalytic recombiners; to exchange information on Member countries' strategies in managing hydrogen mitigation, and to establish dialogue as to differences in approach; to determine whether there is now an adequate technical basis for such strategies or whether more work is needed; to exchange information on future plans for implementation of hydrogen mitigation techniques.

Field-controlled electron transfer and reaction kinetics of the biological catalytic system of microperoxidase-11 and hydrogen peroxide

Directory of Open Access Journals (Sweden)

Yongki Choi

2011-12-01

Full Text Available Controlled reaction kinetics of the bio-catalytic system of microperoxidase-11 and hydrogen peroxide has been achieved using an electrostatic technique. The technique allowed independent control of 1 the thermodynamics of the system using electrochemical setup and 2 the quantum mechanical tunneling at the interface between microperoxidase-11 and the working electrode by applying a gating voltage to the electrode. The cathodic currents of electrodes immobilized with microperoxidase-11 showed a dependence on the gating voltage in the presence of hydrogen peroxide, indicating a controllable reduction reaction. The measured kinetic parameters of the bio-catalytic reduction showed nonlinear dependences on the gating voltage as the result of modified interfacial electron tunnel due to the field induced at the microperoxidase-11-electrode interface. Our results indicate that the kinetics of the reduction of hydrogen peroxide can be controlled by a gating voltage and illustrate the operation of a field-effect bio-catalytic transistor, whose current-generating mechanism is the conversion of hydrogen peroxide to water with the current being controlled by the gating voltage.

A Matlab-Based Graphical User Interface for Simulation and Control Design of a Hydrogen Mixer

Science.gov (United States)

Richter, Hanz; Figueroa, Fernando

2003-01-01

A Graphical User Interface (GUI) that facilitates prediction and control design tasks for a propellant mixer is described. The Hydrogen mixer is used in rocket test stand operations at the NASA John C. Stennis Space Center. The mixer injects gaseous hydrogen (GH2) into a stream of liquid hydrogen (LH2) to obtain a combined flow with desired thermodynamic properties. The flows of GH2 and LH2 into the mixer are regulated by two control valves, and a third control valve is installed at the exit of the mixer to regulate the combined flow. The three valves may be simultaneously operated in order to achieve any desired combination of total flow, exit temperature and mixer pressure within the range of operation. The mixer, thus, constitutes a three-input, three-output system. A mathematical model of the mixer has been obtained and validated with experimental data. The GUI presented here uses the model to predict mixer response under diverse conditions.

A two-year participatory intervention project with owners to reduce lameness and limb abnormalities in working horses in Jaipur, India.

Full Text Available Participatory methods are increasingly used in international human development, but scientific evaluation of their efficacy versus a control group is rare. Working horses support families in impoverished communities. Lameness and limb abnormalities are highly prevalent in these animals and a cause for welfare concern. We aimed to stimulate and evaluate improvements in lameness and limb abnormalities in horses whose owners took part in a 2-year participatory intervention project to reduce lameness (PI versus a control group (C in Jaipur, India.In total, 439 owners of 862 horses participated in the study. PI group owners from 21 communities were encouraged to meet regularly to discuss management and work practices influencing lameness and poor welfare and to track their own progress in improving these. Lameness examinations (41 parameters were conducted at the start of the study (Baseline, and after 1 year and 2 years. Results were compared with control horses from a further 21 communities outside the intervention. Of the 149 horses assessed on all three occasions, PI horses showed significantly (P<0.05 greater improvement than C horses in 20 parameters, most notably overall lameness score, measures of sole pain and range of movement on limb flexion. Control horses showed slight but significantly greater improvements in four parameters, including frog quality in fore and hindlimbs.This participatory intervention succeeded in improving lameness and some limb abnormalities in working horses, by encouraging changes in management and work practices which were feasible within owners' socioeconomic and environmental constraints. Demonstration of the potentially sustainable improvements achieved here should encourage further development of participatory intervention approaches to benefit humans and animals in other contexts.

2017-12-01

Recently, colored H-doped TiO 2 (H-TiO 2 ) has demonstrated enhanced photoelectrochemical (PEC) performance due to its unique crystalline core-disordered shell nanostructures and consequent enhanced conduction behaviors between the core-shell homo-interfaces. Although various hydrogenation approaches to obtain H-TiO 2 have been developed, such as high temperature hydrogen furnace tube annealing, high pressure hydrogen annealing, hydrogen-plasma assisted reaction, aluminum reduction and electrochemical reduction etc., there is still a lack of a hydrogenation approach in a controlled manner where all processing parameters (temperature, time and hydrogen flux) were precisely controlled in order to improve the PEC performance of H-TiO 2 and understand the physical insight of enhanced PEC performance. Here, we report for the first time a controlled and local rapid thermal annealing (RTA) approach to prepare hydrogenated core-shell H-TiO 2 nanorods grown on F:SnO 2 (FTO) substrate in order to address the degradation issue of FTO in the typical TiO 2 nanorods/FTO system observed in the conventional non-RTA treated approaches. Without the FTO degradation in the RTA approach, we systematically studied the intrinsic relationship between the annealing temperature, structural, optical, and photoelectrochemical properties in order to understand the role of the disordered shell on the improved photoelectrochemical behavior of H-TiO 2 nanorods. Our investigation shows that the improvement of PEC performance could be attributed to (i) band gap narrowing from 3.0 to 2.9 eV; (ii) improved optical absorption in the visible range induced by the three-dimensional (3D) morphology and rough surface of the disordered shell; (iii) increased proper donor density; (iv) enhanced electron-hole separation and injection efficiency due to the formation of disordered shell after hydrogenation. The RTA approach developed here can be used as a suitable hydrogenation process for TiO 2 nanorods

The aim of this study was to analyze the relationships between four personality traits (calmness, trainability, dog sociability and boldness) of dogs (Canis familiaris) and dog and owner demographics on a large sample size with 14,004 individuals. German speaking dog owners could characterize their dog by filling out a form on the Internet. There were five demographic variables for dogs and nine for owners. Two statistical methods were used for investigating the associations between personality and demographic traits: the more traditional general linear methods and regression trees that are ideal for analyzing non-linear relationships in the structure of the data. The results showed that calmness is influenced primarily by the dog's age, the neutered status, the number of different types of professional training courses (e.g. obedience, agility) the dog had experienced and the age of acquisition. The least calm dogs were less than 2.5 years old, neutered and acquired after the first 12 weeks of age, while the calmest dogs were older than 6.9 years. Trainability was affected primarily by the training experiences, the dog's age, and the purpose of keeping the dog. The least trainable dogs had not received professional training at all and were older than 3 years. The most trainable dogs were those who participated in three or more types of professional training. Sociability toward conspecifics was mainly determined by the age, sex, training experience and time spent together. The least sociable dogs were older than 4.8 years and the owners spent less than 3h with the dog daily. The most sociable dogs were less than 1.5 years old. Males were less sociable toward their conspecifics than females. Boldness was affected by the sex and age of the dog and the age of acquisition. The least bold were females acquired after the age of 1 year or bred by the owner. The boldest dogs were males, acquired before the age of 12 weeks, and were younger than 2 years old.

This paper addresses the problem of optimization of hydrogen production in continuous anaerobic digesters using a model predictive control (MPC) strategy. The process is described by a dynamic nonlinear model. The influent concentration of molasses together with the effluent substrate and product concentrations of acetate, propionate, butyrate and biomass were estimated by an asymptotic online observer from measurements of gas composition in H{sub 2} and CO{sub 2} and gas flow rate. The observer was tested experimentally before to apply MPC online. The combined strategy (MPC and observer) was used in order to optimize a bioreactor of 2 L. The hydrogen production was increased by 75% up to 8.27mL{sub H{sub 2}} L{sup -1}min{sup -1}, using the influent flow rate as the main control variable while keeping the conversion of the influent concentration higher than 95% and maintaining the temperature at 37 C and pH at 5.5.

The Japan Atomic Energy Research Institute has a demonstration test plan of a hydrogen production system by steam reforming of methane coupling with the High-Temperature Engineering Test Reactor (HTTR). Prior to the coupling of a hydrogen production plant with the HTTR, simulation tests with a mock-up test facility of the HTTR hydrogen production system (HTTR-H2) is underway. The test facility is a 1/30-scale of the HTTR-H2 and simulates key components downstream from an intermediate heat exchanger of the HTTR. The main objective of the simulation tests is the establishment and demonstration of control technology, focusing on the mitigation of a thermal disturbance to the reactor by a steam generator (SG) and on the controllability of the pressure difference between the helium and process gases at the reaction tube in a steam reformer (SR). It was confirmed that the fluctuation of the outlet helium gas temperature at the SG and the pressure difference in the SR can be controlled within the allowable range for the HTTR-H2 in the case of the system controllability test for the fluctuation of chemical reaction. In addition, a dynamic simulation code for the HTTR-H2 was verified with the obtained test data

Domestic Cats (Felis silvestris catus) Do Not Show Signs of Secure Attachment to Their Owners

Science.gov (United States)

Potter, Alice; Mills, Daniel Simon

2015-01-01

The Ainsworth Strange Situation Test (SST) has been widely used to demonstrate that the bond between both children and dogs to their primary carer typically meets the requirements of a secure attachment (i.e. the carer being perceived as a focus of safety and security in otherwise threatening environments), and has been adapted for cats with a similar claim made. However methodological problems in this latter research make the claim that the cat-owner bond is typically a secure attachment, operationally definable by its behaviour in the SST, questionable. We therefore developed an adapted version of the SST with the necessary methodological controls which include a full counterbalance of the procedure. A cross-over design experiment with 20 cat-owner pairs (10 each undertaking one of the two versions of the SST first) and continuous focal sampling was used to record the duration of a range of behavioural states expressed by the cats that might be useful for assessing secure attachment. Since data were not normally distributed, non-parametric analyses were used on those behaviours shown to be reliable across the two versions of the test (which excluded much cat behaviour). Although cats vocalised more when the owner rather the stranger left the cat with the other individual, there was no other evidence consistent with the interpretation of the bond between a cat and its owner meeting the requirements of a secure attachment. These results are consistent with the view that adult cats are typically quite autonomous, even in their social relationships, and not necessarily dependent on others to provide a sense of security and safety. It is concluded that alternative methods need to be developed to characterise the normal psychological features of the cat-owner bond. PMID:26332470

"She's a dog at the end of the day": Guide dog owners' perspectives on the behaviour of their guide dog.

Directory of Open Access Journals (Sweden)

Peter J Craigon

Full Text Available A guide dog is a domestic dog (Canis familiaris that is specifically educated to provide mobility support to a blind or visually impaired owner. Current dog suitability assessments focus on behavioural traits, including: trainability, reactivity or attention to environmental stimuli, low aggressiveness, fearfulness and stress behaviour, energy levels, and attachment behaviour. The aim of this study was to find out which aspects of guide dog behaviour are of key importance to guide dog owners themselves. Sixty-three semi-structured interview surveys were carried out with guide dog owners. Topics included the behaviour of their guide dog both within and outside their working role, and also focused on examples of behaviour which might be considered outside a guide dog owner's typical expectations. Both positive and negative examples and situations were covered. This allowed for the discovery of new perspectives and emerging themes on living and working with a guide dog. Thematic analysis of the results reveals that a dog's safe behaviour in the face of traffic was the most important positive aspect of a guide dog's behaviour and pulling or high tension on the lead and /or harness was the most discussed negative aspect. Other aspects of guide dog behaviour were highlighted as particularly pleasing or disappointing by owners including attentiveness to the task, work, environment and owner; confidence in work and decision making (with confident dogs resulting in confident owners obedience and control; calmness and locating objectives. The results reveal important areas of behaviour that are not currently considered priorities in guide dog assessments; these key areas were consistency of behaviour, the dog's maturity and the dog's behaviour in relation to children. The survey revealed a large range in what owners considered problematic or pleasing behaviours and this highlights the heterogeneity in guide dog owners and the potential multifarious roles

As Medicare Part D contracts apply pressure on the profitability of independent pharmacies, there is concern about their owners' willingness to sign such contracts. Identifying factors affecting independent pharmacy owners' satisfaction with Medicare Part D contracts could inform policy makers in managing Medicare Part D. (1) To identify influences on independent pharmacy owners' satisfaction with Medicare Part D contracts and (2) to characterize comments made by independent pharmacy owners about Medicare Part D. This cross-sectional study used a mail survey of independent pharmacy owners in 15 states comprising 6 Medicare regions to collect information on their most- and least-favorable Medicare Part D contracts, including satisfaction, contract management activities, market position, pharmacy operation, and specific payment levels on brand and generic drugs. Of the 1649 surveys mailed, 296 surveys were analyzed. The regression models for satisfaction with both the least and the most-favorable Part D contracts were significant (Pequity. For the least-favorable contract, influences were negotiation, equity, generic rate bonus, and medication therapy management (MTM) payment. About one-third of the survey respondents made at least 1 comment. The most frequent themes in the comments were that Medicare Part D reimbursement rate is too low (28%) and that contracts are offered without negotiation in a "take it or leave it" manner (20%). Equity, contending, negotiation, generic rate bonus, and MTM payments were identified as the influences of independent pharmacy owners' satisfaction toward Medicare Part D contracts. Generic rate bonus and MTM payment provide additional financial incentives to less financially favorable contracts and, in turn, contribute to independent pharmacy owner's satisfaction toward these contracts.

Mongillo, Paolo; Pitteri, Elisa; Marinelli, Lieta

2017-07-01

Adaptation in human societies requires dogs to pay attention to socially relevant human beings, in contexts that may greatly vary in social complexity. In turn, such selective attention may depend on the dog's training and involvement in specific activities. Therefore, we recruited untrained pet dogs (N=32), dogs trained for agility (N=32) and for animal assisted interventions (N=32) to investigate differences in attention to the owner in relation to the dogs' training/working experience. Average gaze length and frequency of gaze shifting towards the owner were measured in a 'baseline attention test', where dogs were exposed to the owner walking in and out of the experimental room and in a 'selective attention test', where the owner's movements were mirrored by an unfamiliar figurant. In baseline, gazes to the owner by assistance dogs were longer than gazes by untrained dogs, which were longer than gazes by agility dogs. The latter shifted gaze to the owner more frequently than assistance and untrained dogs. In the selective attention test, assistance dogs showed longer and less frequent gazes towards the owner than untrained dogs, with intermediate values for agility dogs. Correlations were found for gaze length between the baseline and selective attention test for untrained and assistance dogs, but not for agility dogs. Therefore, dogs trained for Animal Assisted Interventions express enhanced sustained attention to their owners, and the lack of similar effects in agility dogs suggests that involvement in specific activities is associated with large differences in the patterns of attention paid by dogs to their handler/owner.

Wood fuel supply as a function of forest owner preferences and management styles

International Nuclear Information System (INIS)

Bohlin, F.; Roos, A.

2002-01-01

The commercial demand for wood fuel is rapidly increasing in Sweden, and the domestic supply comes primarily from private non-industrial forest owners. A model was developed to analyse decision-making among these private forest owners. The model covers five factors: economics, transaction costs, concerns about soil fertility, forestry, and previous experience. It was applied in a survey among forest owners in four communities in central Sweden in 1999. Wood fuels had been sold from 60% of the estates. Analysis suggests that the price paid had little influence on the decision to sell. Transaction costs had been alleviated by the traditional timber buyer organizing the fuel trade, and by minimizing measurement in the forest. The primary reason for selling wood fuel was that the harvesting operation cleared the ground of debris. There is a general concern for loss in soil fertility due to wood fuel harvesting which is why some owners do not sell forest fuels. Two types of fuel-selling forest owners were identified: (1) an active manager seeking different gains from wood fuel harvest, and (2) an owner who primarily relies on the advice of the timber buyer. The findings indicate that large-scale traders of wood fuels have to be active in increasing supply, making direct contact with forest owners, and connecting trade with information on ecological and silvicultural effects. Offering ash recycling may enhance supply more than marginal price increases. (author)

African American barbershops and beauty salons are settings that have been identified as a significant and culturally relevant venue to reach minority populations for health promotion activities. By being located in almost every town in the USA, this setting is a viable means to promote healthy lifestyles among African Americans. The purpose of this formative research project was to assess African American barbershop and beauty salon owners' perceptions of providing health promotion programming in their shops, as well as to obtain information on health topics of interest and strategies for implementation. Interviewees were recruited using snowballing among clientele and owner referrals, between November 2014 and August 2015. A total of 20 barbershop and salon owners, across 11 counties in eastern North Carolina, completed face-to-face interviews. Responses were stratified by barbershops and beauty salons. Across both groups, all owners stated it would be a good idea to have health programs/interventions within the shop setting. Most noted topics of interest included diet and nutrition, hypertension, and (wo)men's reproductive health. When asked further about these desired topics, both benefits and relevance to customers and the African American community were the reasons for their selections. In addition, across barbershops and salons, 90 % of owners stated interest in having a program implemented in their shop. This information will be used to guide the development of shop-based interventions, with the aid of a community advisory board composed of shop owners, individual barbers and stylists and customers.

Do Dog Behavioral Characteristics Predict the Quality of the Relationship between Dogs and Their Owners?

Science.gov (United States)

Hoffman, Christy L; Chen, Pan; Serpell, James A; Jacobson, Kristen C

This paper explores whether dog behavioral characteristics predict the quality of the relationship between dogs and their owners (i.e., owner attachment to dog), and whether relations between dog behavior and owner attachment are moderated by demographic characteristics. In this study, N = 92 children and N = 60 adults from 60 dog-owning families completed questionnaires about their attachment to their pet dog, their level of responsibility for that dog, and their general attitudes toward pets. They also rated their dogs on observable behavioral characteristics. Individuals who held positive attitudes about pets and who provided much of their dog's care reported stronger attachments to their dogs. The strength of owners' attachments to their dogs was associated with dog trainability and separation problems. Relationships between owner attachment and both dog excitability and attention-seeking behavior were further moderated by demographic characteristics: for Caucasians but not for non-Caucasians, dog excitability was negatively associated with owner attachment to dog; and for adults, dog attention-seeking behavior was positively associated with owner attachment, but children tended to be highly attached to their dogs, regardless of their dogs' attention-seeking behaviors. This study demonstrates that certain dog behavioral traits are indeed associated with the strength of owners' attachments to their dogs.

Integrated Cost and Schedule Control Systems for Nuclear Power Plant Construction: Leveraging Strategic Advantages to Owners and EPC Firms

Directory of Open Access Journals (Sweden)

Youngsoo Jung

2015-01-01

Full Text Available As the owners expect that the cost and time for nuclear power plant construction would decrease with new entrants into the market, there will be severer competition in the nuclear industry. In order to achieve performance improvement and to attain competitive advantages under the globalized competition, practitioners and researchers in the nuclear industry have recently exerted efforts to develop an advanced and efficient management methodology for the nuclear mega-projects. Among several candidates, integrated cost and schedule control system is of great concern because it can effectively manage the three most important project performances including cost, time, and quality. In this context, the purpose of this paper is to develop a project numbering system (PNS of integrated cost and schedule control system for nuclear power plant construction. Distinct attributes of nuclear power plant construction were investigated first in order to identify influencing variables that characterize real-world implementation of advanced cost and schedule controls. A scenario was then developed and analysed to simulate a case-project. By using this case-project, proposed management requirements, management methods, measurement techniques, data structure, and data collection methods for integrated cost and schedule PNS were illustrated. Finally, findings and implications are outlined, and recommendations for further research are presented.

2017-04-01

Full Text Available The main objective of this study was to evaluate the prevalence of canine obesity and obesity-related metabolic dysfunction (ORMD in the obesogenic area in Spain. The prevalence of overweight/obesity among owners of obese pets was also evaluated. In the sample population studied (93 client-owned dogs, 40.9% of dogs presented obesity (body condition score 7–9/9, 40.9% of dogs presented hypertension, 20.4% of dogs presented fasting hypertriglyceridemia, 20.4% fasting hypercholesterolemia, and 5.4% of dogs presented fasting hyperglycemia. The overall prevalence of ORMD was of 22.6%. Seventy-eight percent of overweight/obese owners had overweight/obese dogs (P < 0.001 including all dogs diagnosed with ORMD. In conclusion, in the studied obesogenic region of Spain, the prevalence of canine obesity and ORMD was shown to be elevated and related to the presence of overweight/obesity in owners. All dogs with ORMD were owned by overweight/obese persons. These results provide new inputs for future studies highlighting the relationship between owner and pet obesity and indicating the need of further efforts to control and reduce obesity prevalence in both.

LIFE STYLE OF RENTED LAND OWNERS IN UBUD SUBDISTRICT

Full Text Available This present study was intended to analyze the Life Style of the Rented Land Owners at Ubud Subdistrict. The problems of the study are formulated as follows: (1 what is the characteristic of the rented land owners at Ubud Subdistrict like? (2 How has the process of life style of the rented land owners at Ubud Subdistrict  taken place? And (3 what is the implication of the life style of the rented land owners on their lives? Qualitative method was employed in the study. The data were processed using observation, interview and documentary techniques. The workability of the law regulating the demand for land at Ubud Subdistrict motivated the land owners to rent out their land to investors. Apart from that, the internal dimension, which is made up of the economical capital, was the most important element as it could activate small, medium and big enterprises. Another aspect was image which was reflected through perception, cognition, motivation, and attitude of individuals as consumers. As an illustration, they built luxurious houses and showed off luxurious cars to show the image that they were new wealthy people. On the other hand, there was external dimension, namely, the highly rapid development of tourism, which could positively and negatively contribute to the life style of the people living at Ubud Subdistrict. Such an implication could not be avoided. The other aspect was consumerism; the consumers were around the symbol and sign. Mass media were the miracles of the object liturgy; pleasure was defined as the realization of freedom, and the human body was the main object of consumers. The last aspect was the government’s policy which determined that Ubud Subdistrict was a tourist destination. As a result, the local people had the opportunity to rent out their land which was used to expand the industry of tourism and to activate the other economic enterprises.

Formation of polyhedral ceria nanoparticles with enhanced catalytic CO oxidation activity in thermal plasma via a hydrogen mediated shape control mechanism

International Nuclear Information System (INIS)

Zheng Jie; Zhang Yaohua; Song Xubo; Li Xingguo

2011-01-01

Ceria nanoparticles with well defined facets are prepared in argon–hydrogen thermal plasma followed by controlled oxidation. With increasing hydrogen fraction in the plasma, a clear sphere-to-polyhedron shape transition is observed. The heat released during the hydrogenation of cerium, which significantly enhances the species mobility on the surface, favors the growth of well defined facets. The polyhedron ceria nanoparticles, though lower in specific surface area, exhibit superior catalytic performance for CO oxidation over the round particles, which is attributed to the higher density of the reactive {200} and {220} facets on the surface. The hydrogen mediated shape control mechanism provides new insights into the shape control of nanoparticles during thermal plasma processing.

While the source of hydrogen constitutes a significant scientific challenge, addressing issues of hydrogen storage, transport, and delivery is equally important. None of the current hydrogen storage options, liquefied or high pressure H{sub 2} gas, metal hydrides, etc.. satisfy criteria of size, costs, kinetics, and safety for use in transportation. In this context, we have discovered a methodology for the production of hydrogen on demand, in high yield, under kinetic control, from organosilane hydrogen carriers derivatives and methanol as co-reagent under mild conditions catalyzed by a cheap ammonium fluoride salt. Finally, the silicon by-products can be efficiently recycle leading to an environmentally friendly source of energy. (author)

Full Text Available Stray animals with incorrect microchip details are less likely to be reclaimed, and unclaimed strays are at increased risk of euthanasia. A retrospective cohort study was performed using 394,747 cats and 904,909 dogs registered with Australia’s largest microchip database to describe animal characteristics, determine whether annual email reminders increased the frequency that owners updated their information, and to compare frequencies of microchip information updates according to pet and owner characteristics. More than twice as many dogs (70% than cats (30% were registered on the database; the most numerous pure-breeds were Ragdoll cats and Staffordshire Bull Terrier dogs, and the number of registered animals per capita varied by Australian state or territory. Owners were more likely (p < 0.001 to update their details soon after they were sent a reminder email, compared to immediately before that email, and there were significant (p < 0.001 differences in the frequency of owner updates by state or territory of residence, animal species, animal age, and socioeconomic index of the owner’s postcode. This research demonstrates that email reminders increase the probability of owners updating their details on the microchip database, and this could reduce the percentages of stray animals that are unclaimed and subsequently euthanized.

Wind power has been identified as one of the most promising sources of renewable energy. However, its diffusion has not been as rapid as anticipated. The objective here is to analyse attitudes towards wind power among Finnish local residents and owners of second homes. First, we assess their existing knowledge of and level of interest in energy issues and wind power. Second, we analyse potential differences in attitudes between the two stakeholder groups when it comes to wind power in general and the proposed wind farm in particular. The study draws on both quantitative survey data and qualitative interview data. One of the key findings concerns the different perceptions among locals and owners of second homes in a rural area. Both groups were interested in questions of energy production and accepted wind power in general. Nevertheless, the proposed project in Ruokolahti seemed to polarize attitudes. This paper offers new insights into attitudes to wind energy among Finnish locals and owners of second homes in the same area. - Highlights: • Studies acceptability of wind power between local residents and owners of second home. • Survey data complemented with semi-structured interviews. • The attitudes differ between locals and owners of second homes in a rural area. • New information regarding differences in wind energy attitudes between Finnish second home owners and locals

Rodríguez-Piñeros, Sandra; Mayett-Moreno, Yesica

2015-03-01

The use of forest land for ecotourism has been well accepted due to its ability to provide income to local people and to conserve the forest. Preparing the forest with infrastructure to attract and educate visitors has been reported of importance. This study applied Q methodology in a small rural community of the State of Puebla, Mexico, to reveal forest owners' perceptions to build infrastructure in their forest as part of their ecotourism project. It also discloses forest owners' underlying motives to use their forest for ecotourism. Ecotourism is perceived as a complementary activity to farming that would allow women to be involved in community development. Low impact infrastructure is desired due to forest owners' perception to preserve the forest for the overall community well-being.

2014-01-01

This paper presents a novel compact and controllable pneumatic generator that uses hydrogen peroxide decomposition. A fuel micro-injector using a piston-pump mechanism is devised and tested to control the chemical decomposition rate. By controlling the injection rate, the feedback controller maintains the pressure of the gas reservoir at a desired pressure level. Thermodynamic analysis and experiments are performed to demonstrate the feasibility of the proposed pneumatic generator. Using a prototype of the pneumatic generator, it takes 6 s to reach 3.5 bars with a reservoir volume of 200 ml at the room temperature, which is sufficiently rapid and effective to maintain the repetitive lifting of a 1 kg mass

Implement of the Owner Distinction Function for Healing-Type Pet Robots

Science.gov (United States)

Nambo, Hidetaka; Kimura, Haruhiko; Hirose, Sadaki

In recent years, a robotics technology is extremely progressive, and robots are widely applied in many fields. One of the most typical robots is a pet robot. The pet robot is based on an animal pet, such as a dog or a cat. Also, it is known that an animal pet has a healing effect. Therefore, the study to apply pet robots to Animal Assisted Therapy instead of an animal pet has begun to be investigated. We, also, have investigated a method of an owner distinction for pet robot, to emphasize a healing effect of pet robots. In this paper, taking account of implementation into pet robots, a real-time owner distinction method is proposed. In the concrete, the method provides a real-time matching algorithm and an oblivion mechanism. The real-time matching means that a matching and a data acquisition are processed simultaneously. The oblivion mechanism is deleting features of owners in the database of the pet robots. Additionally, the mechanism enables to reduce matching costs or size of database and it enables to follow a change of owners. Furthermore, effectivity and a practicality of the method are evaluated by experiments.

Effect of "owners" selection strategies on autumn weight in reindeer (Rangifer t. tarandus calves

2002-03-01

Full Text Available Many northern indigenous peoples, including the Sami are dependent on reindeer herding for their livelihood. In view of the socio-cultural and economical importance of reindeer herding, emphasis should be put on appropriate herd structure and selection strategies that maximise marketable products, such as meat (the primary marketable product nowadays. Empirical observations reveal that within a herd, some owners seem to have better productivity in term of carcass autumn weight of calves, than others. We hypothesized that there may be an "owner" effect in reindeer herding, i.e. some owners may be applying particular selection strategies that might be beneficial. We investigated this in three reindeer grazing districts in South Norway, using mixed linear models. We found that autumn carcass weight of calves varied significantly with year and "owner" within herd in all three districts. Consistently some particular owners within a herd had higher average autumn carcass weight of their calves than others. We attributed this difference to "individual selection strategies", meaning that some owners may follow more accurately the sex, age and weight-based recommended strategy and in addition, they may make superior choices when selecting animals for slaughtering. We conclude that individual owners have the capability, through appropriate selection decisions to improve the average annual autumn weight of their reindeer calves. This might be an important aspect of "Traditional Ecological Knowledge", in addition to the recommended modern sex, age and weight-based selection criteria.

Reducing the frequency of reactor scrams is an important and highly visible task. Scram frequency is one indicator of how consistently a unit is operated within desired bounds and hence is a key performance indicator. To be successful and efficient in this undertaking, diligent effort by the individual utilities should be complimented by collective action to resolve generic problems. The Babcock and Wilcox (B and W) Owners Group is committed to improving the productivity of its operating units and, in particular, to reducing the number of scrams experienced at the units. Toward this goal, the owners group has undertaken several initiatives to improve the reliability and performance of systems that historically have reactor trips. This paper describes those efforts and how they were identified

Influence of owners' attachment style and personality on their dogs' (Canis familiaris separation-related disorder.

Directory of Open Access Journals (Sweden)

Veronika Konok

Full Text Available Previous research has suggested that owners' attitude to their family dogs may contribute to a variety of behaviour problems in the dog, and authors assume that dogs with separation-related disorder (SRD attach differently to the owner than typical dogs do. Our previous research suggested that these dogs may have an insecure attachment style. In the present study we have investigated whether owners' attachment style, personality traits and the personality of the dog influence the occurrence of SRD in the dog. In an internet-based survey 1508 (1185 German and 323 Hungarian dog-owners filled in five questionnaires: Demographic questions, Separation Behaviour Questionnaire (to determine SRD, Human and Dog Big Five Inventory and Adult Attachment Scale. We found that with owners' higher score on attachment avoidance the occurrence of SRD in the dog increases. Dogs scoring higher on the neuroticism scale were more prone to develop SRD. Our results suggest that owners' attachment avoidance may facilitate the development of SRD in dogs. We assume that avoidant owners are less responsive to the dog's needs and do not provide a secure base for the dog when needed. As a result dogs form an insecure attachment and may develop SRD. However, there may be alternative explanations of our findings that we also discuss.

This study maps communication between veterinary surgeons and dog owners on obesity management in four first-opinion practices in the UK. A total of 74 dog owners who met the study's inclusion criteria and 24 veterinary surgeons were interviewed using oral questionnaires between November 2013 and May 2014. The dog owner questionnaire was based on potential discussion areas that could influence an owner's intention to act (initiate a weight loss regime) based on Ajzen's Theory of Planned Behaviour. The veterinary surgeons' questionnaires assessed perception of canine obesity, their personal communication strategies and current practice-level interventions. The findings identify opportunities for more proactive approaches to obesity management by veterinary surgeons and their practices. British Veterinary Association.

Imputation of Housing Rents for Owners Using Models With Heckman Correction

Directory of Open Access Journals (Sweden)

Beat Hulliger

2012-07-01

Full Text Available The direct income of owners and tenants of dwellings is not comparable since the owners have a hidden income from the investment in their dwelling. This hidden income is considered a part of the disposable income of owners. It may be predicted with the help of a linear model of the rent. Since such a model must be developed and estimated for tenants with observed market rents a selection bias may occur. The selection bias can be minimised through a Heckman correction. The paper applies the Heckman correction to data from the Swiss Statistics on Income and Living Conditions. The Heckman method is adapted to the survey context, the modeling process including the choice of covariates is explained and the effect of the prediction using the model is discussed.

Highlights: Black-Right-Pointing-Pointer Dissolved oxygen monitoring is used for automatic dosage of H{sub 2}O{sub 2} in photo-Fenton. Black-Right-Pointing-Pointer PI with anti-windup minimises H{sub 2}O{sub 2} consumption. Black-Right-Pointing-Pointer The H{sub 2}O{sub 2} consumption was reduced up to 50% with respect to manual addition strategies. Black-Right-Pointing-Pointer Appropriate H{sub 2}O{sub 2} dosage is achieved by PI with anti-windup under disturbances. - Abstract: The solar photo-Fenton process is widely used for the elimination of pollutants in aqueous effluent and, as such, is amply cited in the literature. In this process, hydrogen peroxide represents the highest operational cost. Up until now, manual dosing of H{sub 2}O{sub 2} has led to low process performance. Consequently, there is a need to automate the hydrogen peroxide dosage for use in industrial applications. As it has been demonstrated that a relationship exists between dissolved oxygen (DO) concentration and hydrogen peroxide consumption, DO can be used as a variable in optimising the hydrogen peroxide dosage. For this purpose, a model was experimentally obtained linking the dynamic behaviour of DO to hydrogen peroxide consumption. Following this, a control system was developed based on this model. This control system - a proportional and integral controller (PI) with an anti-windup mechanism - has been tested experimentally. The assays were carried out in a pilot plant under sunlight conditions and with paracetamol used as the model pollutant. In comparison with non-assisted addition methods (a sole initial or continuous addition), a decrease of 50% in hydrogen peroxide consumption was achieved when the automatic controller was used, driving an economic saving and an improvement in process efficiency.

Sphere-like and layer-by-layer growth mechanisms of polypyrrole are controlled by changing pyrrole monomer concentration and using carbon nanotubes (CNT) as template. Pristine polypyrrole has sphere-like structures but remarkable change in types of polypyrrole growth is observed from spherical-like to layer-by-layer structures in the presence of CNT. Acid treatment enhances polypyrrole coverage on CNT surface by preventing agglomeration of polypyrrole due to an increase in surface oxygen groups and sp{sup 2} bonds in CNT structure. The crystallinity of powders comparably decreases after polypyrrole coating due to the amorphous structure of polypyrrole and a sharp decrease in the intensity of 002 peak. The influence of surface functionalization and polymer coating on the structural parameters of multi-walled CNT and their composites is investigated by tailoring the feeding ratio of polypyrrole. The hydrogen sorption measurements at ambient conditions by Intelligent Gravimetric Analyzer demonstrate that hydrogen uptake of CNT/polypyrrole composite is 1.66 wt.% which is almost 3 times higher than that of pristine CNT. Higher hydrogen uptake values are obtained by keeping the mass ratio of pyrrole monomer and CNT equal by using non-functionalized CNT in composite production. Hydrogen adsorption/desorption kinetics of polypyrrole/CNT composites is improved by increasing adsorption sites after polymer coating and acid treatment. The desorption curves of these modified surfaces are higher than their adsorption curves at lower pressures and hysteresis loop is observed in their isotherms since hydrogen is chemically bonded to the modified surfaces by the conversion of carbon atoms from sp{sup 2} to sp{sup 3} hybridization. - Highlights: • Growth mechanisms of polypyrrole are controlled by changing monomer concentration. • Lamellar structure is formed by using pristine CNT at high monomer concentration. • Homogeneous polymer coating is achieved on the surface of

The Japan Atomic Energy Agency has been planning the demonstration test of hydrogen production with the High Temperature Engineering Test Reactor (HTTR). In a HTTR hydrogen production system (HTTR-H2), it is required to control a primary helium temperature within an allowable value at a reactor inlet to prevent a reactor scram. A cooling system for a secondary helium with a steam generator (SG) and a radiator is installed at the downstream of a chemical rector in a secondary helium loop in order to mitigate the thermal disturbance caused by the hydrogen production system. Prior to HTTR-H2, the simulation test with a mock-up test facility has been carried out to establish the controllability on the helium temperature using the cooling system against the loss of chemical reaction. It was confirmed that the fluctuations of the helium temperature at chemical reactor outlet, more than 200 K, at the loss of chemical reaction could be successfully mitigated within the target of ±10 K at SG outlet. A dynamic simulation code of the cooling system for HTTR-H2 was verified with the obtained test data

Control of microbially generated hydrogen sulfide in produced waters

Energy Technology Data Exchange (ETDEWEB)

Burger, E.D.; Vance, I.; Gammack, G.F.; Duncan, S.E.

1995-12-31

Production of hydrogen sulfide in produced waters due to the activity of sulfate-reducing bacteria (SRB) is a potentially serious problem. The hydrogen sulfide is not only a safety and environmental concern, it also contributes to corrosion, solids formation, a reduction in produced oil and gas values, and limitations on water discharge. Waters produced from seawater-flooded reservoirs typically contain all of the nutrients required to support SRB metabolism. Surface processing facilities provide a favorable environment in which SRB flourish, converting water-borne nutrients into biomass and H{sub 2}S. This paper will present results from a field trial in which a new technology for the biochemical control of SRB metabolism was successfully applied. A slip stream of water downstream of separators on a produced water handling facility was routed through a bioreactor in a side-steam device where microbial growth was allowed to develop fully. This slip stream was then treated with slug doses of two forms of a proprietary, nonbiocidal metabolic modifier. Results indicated that H{sub 2}S production was halted almost immediately and that the residual effect of the treatment lasted for well over one week.

One of the IAEA's statutory objectives is to 'seek to accelerate and enlarge the contribution of atomic energy to peace, health and prosperity throughout the world.' One way this objective is achieved is through the publication of a range of technical series. Two of these are the IAEA Nuclear Energy Series and the IAEA Safety Standards Series. According to Article III.A.6 of the IAEA Statute, the safety standards establish 'standards of safety for protection of health and minimization of danger to life and property'. The safety standards include the Safety Fundamentals, Safety Requirements and Safety Guides. These standards are written primarily in a regulatory style, and are binding on the IAEA for its own programmes. The principal users are the regulatory bodies in Member States and other national authorities. The IAEA Nuclear Energy Series comprises reports designed to encourage and assist R and D on, and application of, nuclear energy for peaceful uses. This includes practical examples to be used by owners and operators of utilities in Member States, implementing organizations, academia, and government officials, among others. This information is presented in guides, reports on technology status and advances, and best practices for peaceful uses of nuclear energy based on inputs from international experts. The IAEA Nuclear Energy Series complements the IAEA Safety Standards Series. Nuclear generated hydrogen has important potential advantages over other sources that will be considered for a growing hydrogen share in a future world energy economy. Still, there are technical uncertainties in nuclear hydrogen processes that need to be addressed through a vigorous research and development effort. Safety issues as well as hydrogen storage and distribution are important areas of research to be undertaken to support a successful hydrogen economy in the future. The hydrogen economy is gaining higher visibility and stronger political support in several parts of the

Enhancement of hydrogen production during waste activated sludge anaerobic fermentation by carbohydrate substrate addition and pH control.

Science.gov (United States)

Chen, Yinguang; Xiao, Naidong; Zhao, Yuxiao; Mu, Hui

2012-06-01

The effects of carbohydrate/protein ratio (CH/Pr) and pH on hydrogen production from waste activated sludge (WAS) were investigated. Firstly, the optimal pH value for hydrogen production was influenced by the CH/Pr ratio, which was pH 10, 9, 8, 8, 8 and 6 at the CH/Pr ratio (COD based) of 0.2 (sole sludge), 1, 2.4, 3.8, 5 and 6.6, respectively. The maximal hydrogen production (100.6 mL/g-COD) was achieved at CH/Pr of 5 and pH 8, which was due to the synergistic effect of carbohydrate addition on hydrogen production, the enhancement of sludge protein degradation and protease and amylase activities, and the suitable fermentation pathway for hydrogen production. As hydrogen consumption was observed at pH 8, in order to further increase hydrogen production a two-step pH control strategy (pH 8+pH 10) was developed and the hydrogen production was further improved by 17.6%.

Effects of methanogenic effluent recycle on fermentative hydrogen production

Energy Technology Data Exchange (ETDEWEB)

Kraemer, J.T.; Bagley, D.M. [Toronto Univ., ON (Canada). Dept. of Civil Engineering

2004-07-01

Most research on fermentative hydrogen production has focused on optimizing the process and not on the practicalities of pH control although active pH control in a hydrogen reactor is necessary for stable and efficient performance. Batch experiments have shown that hydrogen ceases to be produced when there is no pH control. This study determined if recycle effluent from the methane reactor of a two-phase hydrogen-producing system would reduce the external alkali needed for pH control in a hydrogen reactor. It also determined if recycle affected the performance of the hydrogen reactor and the overall two-phase system. This paper describes the experimental laboratory-scale, two-phase hydrogen producing system which was operated alternately with and without effluent recycle from a methane reactor to the hydrogen reactor. The two-phase hydrogen producing system yielded 5.7 times more energy recovery than that obtained by the fermentative hydrogen producing reactor alone. The use of effluent from the methane reactor can reduce the operational cost of external alkali for pH control. 6 refs., 5 figs.

Knowledge and disease management skills of cattle owners on East Coast Fever and Foot and Mouth Disease in Kazungula and Livingstone Districts of Zambia

Directory of Open Access Journals (Sweden)

Chisembele, C.

2005-01-01

Full Text Available Effective animal disease control and prevention should be based on accurate information from the field. Part of this field information can be obtained from the cattle owners. In order to assess their disease knowledge, a survey focusing on East Coast Fever (ECF and Foot and Mouth Disease (FMD was organised among 302 cattle owners from the Kazungula and Livingstone Districts of the Southern Province of Zambia. The cattle owners' level of knowledge of ECF was low (34% with most of those able to describe the disease belonging to the endemic zone where ECF caused high death rates in cattle. A larger proportion of the cattle owners (46% were able to give an adequate description of FMD symptoms. It reached up to 61% in the FMD high-risk zone. Reporting to the animal health service providers appeared to be low. The results of the survey showed that attempts should be made to improve the cattle owners' knowledge and response to important diseases by carrying out more extension and sensitization activities. This is especially so in areas of low infection or where the disease was experienced long time ago.

Heliostat-field gain-scheduling control applied to a two-step solar hydrogen production plant

International Nuclear Information System (INIS)

Roca, Lidia; Calle, Alberto de la; Yebra, Luis J.

2013-01-01

Highlights: ► A control system is proposed for a solar reactor system which produces hydrogen. ► The controller chooses which heliostats from the solar field must be focused. ► A gain scheduling scheme is included to deal with different system dynamics. ► The scheme is tested and tunned in simulation. ► Real experiments show the promising results of this work. -- Abstract: This article describes a temperature control structure designed for the interior of a solar hydrogen reactor based on a two-step ferrite-redox technology. Until now, this temperature has been controlled by manual selection of the heliostats to be focused on the receiver targets. However, the strong system dependency on operating conditions suggests that the procedure be automated in order to ensure the desired setpoint change response. The aims are to maintain the desired temperatures and to make the setpoint switch as fast as possible, keeping plant conditions within the margins of safety. The scheme proposed includes a procedure for selecting the heliostats to be focused on the reactor by using a simple model of the solar field and a gain scheduling control system which changes the control tuning parameters to deal with the varying dynamics observed during the process. Real experiments show the promising results of this work.

Small tourism accommodation business owners in Ghana: a factor analysis of motivations and challenges

J Mensah-Ansah

2014-01-01

Full Text Available Five hundred and five small tourism accommodation business owners in Ghana were surveyed to determine their motivation for owning/operating a small tourism business and the challenges they encounter. Tourism accommodation business owners indicated factors such as maintaining lifestyle, being their own bosses, capitalising on a business opportunity, generation of retirement income influence the decision to own/operate a small tourism accommodation businesses. These variables can be categorized as non-economic and economic factors. It was found that though the owners were motivated by commercial enterprise goals, these are subordinated to the pursuit of socially driven lifestyle motivation factors. Small tourism accommodation business owners in Ghana perceive the non-availability of skilled hospitality personnel and limited access to structured hospitality training programmes as the greatest challenge facing their industry.

Steam Generator Owners Group PWR secondary water chemistry guidelines

International Nuclear Information System (INIS)

Welty, C.S. Jr.; Green, S.J.

1985-01-01

In 1981 the Steam Generator Owners Group (SGOG), a group of domestic and foreign pressurized water reactor (PWR) owners, developed and issued the PWR secondary water chemistry guidelines. The guidelines were prepared in response to the growing recognition that a majority of the problems causing reduced steam generator reliability (e.g., denting, wasteage, pitting, etc.) were related to secondary (steam) side water purity. The guidelines were subsequently issued as an Electric Power Research Institute (EPRI) report. In 1984 they were revised to reflect industry experience in adopting the original issuance and to incorporate new information on causes of corrosion damage. The guidelines have been endorsed and their adoption recommended by the SGOG

The objective of this study is to experimentally investigate the potential for autoignition and combustion of hydrogen-sodium mixtures which may be produced in LMFBR accidents. The purpose and ultimate usefulness of this work is to provide data that will establish the validity and acceptability of mechanisms inherent to the LMFBR that could either prevent or delay the accumulation of hydrogen gas to less than 4 percent (V) in the Reactor Containment Building (RCB) under accident conditions. The results to date indicate that sodium and sodium-hydrogen mixtures such as may be expected during LMFBR postulated accidents will ignite upon entering an air atmosphere and that the hydrogen present will be essentially all consumed until such time that the oxygen concentration is depleted

2011-01-01

A model of parental sensitivity in caregiving informs later romantic relationships and is transmitted in caregiving behaviours to children. Differences in parental caregiving contribute to individual differences in infant attachment style. The owner/dog bond mirrors this relationship as dog careseeking activates owner caregiving. The aim of this thesis was to investigate the role of individual differences in owner caregiving on dog attachment style.The first study defined dog attachment style...

Evaluating the effects of local floodplain management policies on property owner behavior

Science.gov (United States)

Bollens, Scott A.; Kaiser, Edward J.; Burby, Raymond J.

1988-05-01

Floodplain management programs have been adopted by more than 85% of local governments in the nation with designated flood hazard areas. Yet, there has been little evaluation of the influence of floodplain policies on private sector decisions. This article examines the degree to which riverine floodplain management affects purchase and mitigation decisions made by owners of developed floodplain property in ten selected cities in the United States. We find that the stringency of such policies does not lessen floodplain property buying because of the overriding importance of site amenity factors. Indeed, flood protection measures incorporated into development projects appear to add to the attractiveness of floodplain location by increasing the perceived safety from the hazard. Property owner responses to the flood hazard after occupancy involve political action more often than individual on-site mitigation. Floodplain programs only minimally encourage on-site mitigation by the owner because most owners have not experienced a flood and many are unaware of the flood threat. It is suggested that floodplain programs will be more effective in meeting their objectives if they are directed at intervention points earlier in the land conversion process.

The thermochemical Copper-Chlorine (Cu-Cl) cycle is an emerging new method of nuclear-based hydrogen production. In the process, water is decomposed into hydrogen and oxygen through several physical and chemical processes. In this paper, a Distributed Control System (DCS) is designed for the thermochemical Cu-Cl cycle. The architecture and the communication networks of the DCS are discussed. Reliability of the DCS is assessed using fault trees. In the assessment, the impact of the malfunction of the actuators, sensors, controllers and communication networks on the overall system reliability is investigated. This provides key information for the selection of control system components, and determination of their inspection frequency and maintenance strategy. The hydrogen reactor unit, which is one of the major components in the thermochemical Cu-Cl cycle, is used to demonstrate the detailed design and analysis. (author)

Examining dog owners' beliefs regarding rabies vaccination during government-funded vaccine clinics in Grenada to improve vaccine coverage rates.

Science.gov (United States)

Thomas, D; Delgado, A; Louison, B; Lefrancois, T; Shaw, J

2013-07-01

Vaccination of domestic pets is an important component of rabies control and prevention in countries where the disease is maintained in a wildlife reservoir. In Grenada, vaccine coverage rates were low, despite extensive public education and advertising of government-sponsored vaccine clinics where rabies vaccine is administered to animals at no cost to animal owners. Information was needed on reasons for decreased dog owner participation in government-funded rabies vaccination clinics. A total of 120 dog owners from 6 different parishes were asked to complete a questionnaire assessing their currently held beliefs about rabies vaccination and perception of the risk posed by rabies. Over 70% of respondents believed that problems in the organization and management of clinic sites could allow for fighting between dogs or disease spread among dogs, while 35% of owners did not believe that they had the ability or adequate help to bring their dogs to the clinic sites. Recommendations for improving vaccine coverage rates included: improved scheduling of clinic sites and dates; increased biosecurity at clinic locations; focused advertising on the availability of home visits, particularly for aggressive dogs or dogs with visible skin-related diseases such as mange; and the recruitment of community volunteers to assist with bringing dogs to the clinic sites.

2017-08-01

Watermarking is the imperceptible embedding of watermark bits into multimedia data in order to use for different applications. Among all its applications, copyright protection is the most prominent usage which conceals information about the owner in the carrier, so as to prohibit others from assertion copyright. This application requires high level of robustness. In this paper, a new blind quantum copyright protection method based on owners's signature in RGB images is proposed. The method utilizes one of the RGB channels as indicator and two remained channels are used for embedding information about the owner. In our contribution the owner's signature is considered as a text. Therefore, in order to embed in colored image as watermark, a new quantum representation of text based on ASCII character set is offered. Experimental results which are analyzed in MATLAB environment, exhibit that the presented scheme shows good performance against attacks and can be used to find out who the real owner is. Finally, the discussed quantum copyright protection method is compared with a related work that our analysis confirm that the presented scheme is more secure and applicable than the previous ones currently found in the literature.

Do Dog Behavioral Characteristics Predict the Quality of the Relationship between Dogs and Their Owners?

Hoffman, Christy L.; Chen, Pan; Serpell, James A.; Jacobson, Kristen C.

2014-01-01

This paper explores whether dog behavioral characteristics predict the quality of the relationship between dogs and their owners (i.e., owner attachment to dog), and whether relations between dog behavior and owner attachment are moderated by demographic characteristics. In this study, N = 92 children and N = 60 adults from 60 dog-owning families completed questionnaires about their attachment to their pet dog, their level of responsibility for that dog, and their general attitudes toward pets. They also rated their dogs on observable behavioral characteristics. Individuals who held positive attitudes about pets and who provided much of their dog’s care reported stronger attachments to their dogs. The strength of owners’ attachments to their dogs was associated with dog trainability and separation problems. Relationships between owner attachment and both dog excitability and attention-seeking behavior were further moderated by demographic characteristics: for Caucasians but not for non-Caucasians, dog excitability was negatively associated with owner attachment to dog; and for adults, dog attention-seeking behavior was positively associated with owner attachment, but children tended to be highly attached to their dogs, regardless of their dogs’ attention-seeking behaviors. This study demonstrates that certain dog behavioral traits are indeed associated with the strength of owners’ attachments to their dogs. PMID:25685855

To evaluate owner experiences and adherence to home-cooked diet recipes for dogs. Clients of a veterinary teaching hospital clinical nutrition service who had a home-cooked diet recipe formulated for their dogs between March 2011 and December 2013 were given a survey by email, postal mail and telephone. Survey questions addressed motivations, positive and negative aspects of feeding home-cooked diets and current feeding practices. Responses were compared to animals' medical records to determine adherence. Of the 93 owners who were contacted, 53 (57%) completed the survey. Of the 53 respondents, 43 owners (81%) reported that they were still feeding an home-cooked diet or had fed an home-cooked diet until the time of their dogs' deaths. The most common motivation for feeding a home-cooked diet was suitability for specific medical needs. Of the 30 surveys that included a complete diet history, only four (13%) demonstrated exact adherence to home-cooked diet recipes. Most respondents liked and continued to feed a home-cooked diet, but few owners adhered to prescribed recipes and many dogs required recipe modifications. It is important to counsel dog owners about benefits and drawbacks of feeding home-cooked diets, importance of recipe adherence and necessity for follow-up after diet formulation with a board-certified veterinary nutritionist. © 2015 British Small Animal Veterinary Association.

Full Text Available The attitude of greenhouse owner as the basis of agricultural production towards sustainable agriculture could be grounds for increasing the sustainability of this type of cultivation system. Therefore, the main purpose of this study is to investigate the factors affecting the attitude of greenhouse owners towards sustainability in the Alborz province. The target population for this study consisted of all active greenhouse owners in the Alborz province (N=366. The sample size was determined by using Cochran’s formula (n=155 and using the proportional stratified random sampling method. The validity was confirmed by a panel of experts and its reliability was established by Cronbach's Alpha coefficient (0.85. The results showed that the attitude of 41 percent of the respondents towards sustainability was positive. Also, there were significant differences between the attitudes of the respondents in the group with related education and unrelated education group. Correlation analysis showed that the there is a positive relation between attitude towards searching behavior and the use of communication channels. In addition, the results of multiple regression analysis indicated that about 40 percent of the attitudes of greenhouse owner towards sustainable agriculture are explained by 4 variables. The result of this study indicate that by using different means of providing information and training, we can change the attitudes of greenhouse owners and lead them to produce more sustainable and healthy product.

Swedish district heating - owners, prices and profitability

International Nuclear Information System (INIS)

Andersson, Sofie; Werner, S.

2001-01-01

Owners, prices and profitability are examined in this report for 152 Swedish district heating companies during 1999. Only public information available has been used: Prices from a national annual consumer study, energy supplied, lengths of district heating pipes installed, and average prices for energy supplied. These companies are responsible for 96 % of all district heat supplied in Sweden. District heating systems owned by municipalities were responsible for 65 % of all district heat supply, while the share of power companies was 34 %. Other private owners accounted for 1 %. Only 12 % of the board members are women and more than 40 % of the companies have no woman in the board. The prices gathered by the annual consumer study are good estimates of the price level of district heating in Sweden. The average revenues are only 4,1 % lower than the effective average of prices gathered. Price of district heating decrease with size and market share. Use of combined heat and power plants decrease prices slightly. Lower prices with size can mainly be explained by lower energy supply costs. Calculated rates of return in relation to calculated replacement values increase slightly by size and are almost independent of age and market share. The purport of these conclusions is that the district heating companies share the cost reduction from size with their customers, while the whole benefit from high market shares is repaid to the customers. Calculated rates of return vary among the owner groups examined. Lower rates are accepted by municipalities, while power companies have higher rates at the average costs used. Total replacement costs for the 152 companies has been estimated to 89 billion Swedish crowns or 10 billion Euro. Only correlation analyses using one dimension have been used in this study. A higher degree of quality can be obtained by using multi-dimensional analyses

To characterize patterns of dog and cat ownership and veterinary service use among Latino dog and cat owners with various degrees of English-language proficiency. DESIGN :Cross-sectional telephone survey. Data from 393 Latino pet owners. Telephone surveys were conducted with Latino dog and cat owners from a random sample of US households to determine the number of dogs and cats owned, factors associated with veterinary service use, and satisfaction with veterinary care. 393 of 1,026 (38.3%) respondents were pet owners. Two hundred fifty-nine of 330 (78.5%) dog owners and 70 of 115 (60.9%) cat owners reported taking their pet to the veterinarian in the past 12 months, most commonly for vaccination or examination or because of illness. Respondents were most satisfied with veterinary care provided, least satisfied with cost, and moderately satisfied with quality of communication. English-language proficiency was not significantly associated with whether owners sought veterinary care. A large proportion of respondents who wanted to receive pet health information in Spanish described themselves as speaking English well or very well. Although having limited proficiency in English was not associated with Latino pet owners seeking veterinary care, opportunities exist for veterinary personnel to improve communications with these clients. Personnel can assess their clients' language needs by asking each about the language in which they would prefer to receive their pet's health information.

2015-11-01

Full Text Available Despite the support extended to the small business sector in South Africa, the growth and survival rates of small, medium, and micro-sized enterprises (SMMEs are lower than expected. This paper investigates business owner and stakeholder perceptions of barriers and enablers of the start-up, survival, and growth of SMMEs in the South African retail sector. A qualitative research design using semi-structured interviews was employed for data collection from samples of stakeholders and business owners. Framework analysis was used to analyse both sets of data. The findings show that the stakeholders and business owners consider the lack of support, competition, skills shortages, and poor internal controls as the key barriers to the start-up, survival, and growth of SMMEs. Stakeholders considered the business environment as the key enabler while the business owners regarded increasing demand as the key enabler. To address the barriers, recommendations relating to skills development, funding, shelter and services, and other business development resources are presented

Born to roam? Surveying cat owners in Tasmania, Australia, to identify the drivers and barriers to cat containment.

McLeod, Lynette J; Hine, Donald W; Bengsen, Andrew J

2015-12-01

Free-roaming domestic cats, Felis catus, are a major public nuisance in neighbourhoods across the world, and have been linked to biodiversity loss and a host of community health problems. Owners who let their cats roam, also place their cats at risk of serious injury. One management strategy that is gaining considerable support involves encouraging cat owners to contain their pets within their property. Contemporary behaviour change models highlight the importance of identifying drivers and barriers that encourage and discourage target behaviours such as cat containment. Results from a random dial phone survey of 356 cat owners in northern Tasmania identified four distinct cat containment profiles: owners who contained their cat all the time, owners who only contained their cat at night, owners who sporadically contained their cat with no set routine, and owners who made no attempt to contain their pet. Our results indicated that cat-owners' decisions to contain or not contain their cats were guided by a range of factors including owners' beliefs about their ability to implement an effective containment strategy and their views about the physical and psychological needs of their cats. The results are discussed in terms of improving the behavioural effectiveness of cat containment interventions by selecting appropriate behavioural change tools for the identified drivers and barriers, and developing targeted engagement strategies and messaging.

2018-03-01

One of major challenge in bio-hydrogen production process by using MEC process is nonlinear and highly complex system. This is mainly due to the presence of microbial interactions and highly complex phenomena in the system. Its complexity makes MEC system difficult to operate and control under optimal conditions. Thus, precise control is required for the MEC reactor, so that the amount of current required to produce hydrogen gas can be controlled according to the composition of the substrate in the reactor. In this work, two schemes for controlling the current and voltage of MEC were evaluated. The controllers evaluated are PID and Inverse neural network (NN) controller. The comparative study has been carried out under optimal condition for the production of bio-hydrogen gas wherein the controller output is based on the correlation of optimal current and voltage to the MEC. Various simulation tests involving multiple set-point changes and disturbances rejection have been evaluated and the performances of both controllers are discussed. The neural network-based controller results in fast response time and less overshoots while the offset effects are minimal. In conclusion, the Inverse neural network (NN)-based controllers provide better control performance for the MEC system compared to the PID controller.

Calls from private well owners to the wellcare® Hotline during 2013 identified key knowledge gaps regarding well stewardship; well owners are generally not testing or maintaining their wells, have questions about well water testing treatment, and concerns about well water contaminants

Fatigue behavior of niobium--hydrogen alloys

International Nuclear Information System (INIS)

Chung, D.W.; Stoloff, N.S.

1978-01-01

The effects of hydrogen on room temperature fatigue behavior of niobium were investigated under both high frequency stress control and low frequency strain control conditions, in air. Hydrogen markedly improved the fatigue life in high frequency tests, while low frequency tests resulted in decreased fatigue life with increasing hydrogen content. Notches in hydrogen-charged alloys reduced high cycle life significantly but had little effect on low cycle tests. Fracture surfaces of annealed niobium mainly exhibited striations, with numerous cracks originating at troughs of striated bands in both stress and strain control tests. The fracture mode for alloys with hydrogen in solution was mixed, with striations interspersed with cleavage facets at high frequencies but generally cleavage steps at low frequencies. For the hydrided alloys, distinctive steps of mixed ductile-brittle appearance were revealed under high frequency conditions, but large cleavage facets only were observed for low frequency tests. The results are discussed in terms of the effects of hydrogen on the cyclic strain hardening rate, as well as on fatigue strength and ductility of niobium

Microcontroller based instrumentation for heater control circuit of tin oxide based hydrogen sensor

International Nuclear Information System (INIS)

Premalatha, S.; Krithika, P.; Gunasekaran, G.; Ramakrishnan, R.; Ramanarayanan, R.R.; Prabhu, E.; Jayaraman, V.; Parthasarathy, R.

2015-01-01

A thin film sensor based on tin oxide developed in IGCAR is used to monitor very low levels of hydrogen (concentration ranging from 2 ppm to 80 ppm). The heater and the sensor patterns are integrated on a miniature alumina substrate and necessary electrical leads are taken out. For proper functioning of the sensor, the heater has to be maintained at a constant temperature of 350°C. The sensor output (voltage signal) varies with H 2 concentration. In fast breeder reactors, liquid sodium is used as coolant. The sensor is used to detect water/steam leak in secondary sodium circuit. During the start up of the reactor, steam leak into sodium circuit generates hydrogen gas as a product that doesn't dissolve in sodium, but escapes to the surge tank containing argon i.e. in cover gas plenum of sodium circuit. On-line monitoring of hydrogen in cover gas is done to detect an event of water/steam leakage. The focus of this project is on the instrumentation pertaining to the temperature control for the sensor heater. The tin oxide based hydrogen sensor is embedded in a substrate which consists of a platinum heater, essentially a resistor. There is no provision of embedding a temperature sensor on the heater surface due to the physical constraints, without which maintaining a constant heater temperature is a complex task

Jin, Rencheng; Chen, Gang; Pei, Jian; Sun, Jingxue; Wang, Yang

2011-09-01

The controlled synthesis of one-dimensional and three-dimensional Sb(2)Se(3) nanostructures has been achieved by a facile solvothermal process in the presence of citric acid. By simply controlling the concentration of citric acid, the nucleation, growth direction and exposed facet can be readily tuned, which brings the different morphologies and nanostructures to the final products. The as-prepared products have been characterized by means of X-ray diffraction, field-emission scanning electron microscopy, transmission electron microscopy (TEM), high-resolution TEM and selected area electron diffraction. Based on the electron microscope observations, a possible growth mechanism of Sb(2)Se(3) with distinctive morphologies including ultralong nanobelts, hierarchical urchin-like nanostructures is proposed and discussed in detail. The electrochemical hydrogen storage measurements reveal that the morphology plays a key role on the hydrogen storage capacity of Sb(2)Se(3) nanostructures. The Sb(2)Se(3) ultralong nanobelts with high percentage of {-111} facets exhibit higher hydrogen storage capacity (228.5 mA h g(-1)) and better cycle stability at room temperature.

THE PARTICULARITIES OF LEADERSHIP STYLES AMONG DUTCH SMALL AND MEDIUM BUSINESS OWNERS

Directory of Open Access Journals (Sweden)

LAURENȚIU-STELIAN MIHAI

2015-12-01

Full Text Available This article aims to analyze the particularities of the leadership styles practiced by the small and medium business owners from a developed western European country, the Netherlands. The three leadership styles that we have used in our research are Autocratic, Democratic and Laissez-faire, the difference between them being the way the leaders make decisions, their involvement in the day to day activities and the degree of freedom and responsibility that their giving their subordinates. The main research instrument used was a 23 questions survey, based on which we could determine the dominant leadership style for each respondent. This survey has been applied on a sample of 128 Dutch small and medium business owners, from which 100 responses could be used for the actual research. The results have shown us that the dominant leadership styles among Dutch SME owners is the democratic one and we have also identified a series of factors, such as the company’s age and the owner’s sex that are having a significant influence upon the practiced style. The results of this research will be used in a future study in which we will make a comparison between the particularities of leadership styles among Romanian and Dutch small and medium business owners.

Border Collie Collapse: Owner Survey Results and Veterinary Description of Videotaped Episodes.

Taylor, Susan; Minor, Katie; Shmon, Cindy L; Shelton, G Diane; Patterson, Edward E; Mickelson, James R

Completed surveys were obtained from owners of 165 border collies experiencing repeated episodes of abnormal gait or collapse during strenuous exercise. Unremarkable veterinary evaluation and lack of disease progression over time made common systemic, cardiac, and neurologic causes of exercise intolerance unlikely. Survey questions addressed signalment, age of onset, description of episodes, and owner perception of factors associated with collapse. Most dogs were young adults (median 2 yr) when episodes began, and they had experienced from 2 to more than 100 episodes (median 6) prior to their owners completing the survey. Retrieving was the activity most commonly associated with episodes (112/165 dogs, 68%), followed by herding stock (39/165 dogs, 24%). Owners reported that high environmental temperatures (111/165 dogs, 67%) and excitement (67/165 dogs, 41%) increased the likelihood of their dog having an episode during strenuous activity. Veterinary evaluation of videotapes of presumed border collie collapse (BCC) episodes (40 dogs) were used to provide a description of the typical features of BCC episodes. Altered mentation, symmetrical ataxia affecting all four limbs, increased pelvic limb extensor tone and toe scuffing or knuckling, truncal swaying, and falling to the side were common features, suggesting that BCC may be an episodic diffuse central nervous system disorder.

Optimizing the Binding Energy of Hydrogen on Nanostructured Carbon Materials through Structure Control and Chemical Doping

Energy Technology Data Exchange (ETDEWEB)

Jie Liu

2011-02-01

The DOE Hydrogen Sorption Center of Excellence (HSCoE) was formed in 2005 to develop materials for hydrogen storage systems to be used in light-duty vehicles. The HSCoE and two related centers of excellence were created as follow-on activities to the DOE Office of Energy Efficiency and Renewable Energy’s (EERE’s) Hydrogen Storage Grand Challenge Solicitation issued in FY 2003. The Hydrogen Sorption Center of Excellence (HSCoE) focuses on developing high-capacity sorbents with the goal to operate at temperatures and pressures approaching ambient and be efficiently and quickly charged in the tank with minimal energy requirements and penalties to the hydrogen fuel infrastructure. The work was directed at overcoming barriers to achieving DOE system goals and identifying pathways to meet the hydrogen storage system targets. To ensure that the development activities were performed as efficiently as possible, the HSCoE formed complementary, focused development clusters based on the following four sorption-based hydrogen storage mechanisms: 1. Physisorption on high specific surface area and nominally single element materials 2. Enhanced H2 binding in Substituted/heterogeneous materials 3. Strong and/or multiple H2 binding from coordinated but electronically unsatruated metal centers 4. Weak Chemisorption/Spillover. As a member of the team, our group at Duke studied the synthesis of various carbon-based materials, including carbon nanotubes and microporous carbon materials with controlled porosity. We worked closely with other team members to study the effect of pore size on the binding energy of hydrogen to the carbon –based materials. Our initial project focus was on the synthesis and purification of small diameter, single-walled carbon nanotubes (SWNTs) with well-controlled diameters for the study of their hydrogen storage properties as a function of diameters. We developed a chemical vapor deposition method that synthesized gram quantities of carbon nanotubes with

Pollard, D; Wylie, C E; Verheyen, K L P; Newton, J R

2017-11-01

Use of owner-reported data could further epidemiological knowledge of equine laminitis. However, owner recognition of laminitis has not previously been assessed. The primary objective was to establish whether cases of owner-suspected laminitis would be confirmed as laminitis by the attending veterinary surgeon. Secondary objectives were to compare owner- and veterinary-reported information from veterinary-confirmed cases of equine laminitis. Cross-sectional study. Twenty-five British veterinary practices were invited to submit laminitis reporting forms (LRFs) for active laminitis cases attended between January 2014 and October 2015; detailing 27 clinical signs, 5 underlying conditions and 7 risk factors associated with laminitis. Owners were invited to independently complete a modified LRF if reason for the veterinary visit was suspicion of laminitis. Differences between paired veterinary and owner LRFs, and between cases where owners did and did not recognise laminitis, were assessed using McNemar's and Fisher's Exact tests, respectively. Veterinary LRFs were received for 93 veterinary-diagnosed laminitis cases. All 51 owner-suspected cases were confirmed by veterinary diagnosis, with the remaining 42 (45.2%) not recognised as laminitis by owners. Undefined lameness, foot abscesses, colic and stiffness were common reasons for owner-requested veterinary visits in owner-unrecognised cases. 'Divergent growth rings' (prevalence difference: +27.3%, P = 0.01) and 'breed type' (prevalence difference: +21.2%, P = 0.04) were more commonly reported by veterinary surgeons in owner-recognised compared to owner-unrecognised cases. 'Difficulty turning', 'shifting weight' and risk factor 'body condition' were more frequently reported by veterinary surgeons whilst 'increased hoof temperature' was reported more frequently by owners. The limited clinical data restricted statistical inferences regarding the secondary objectives. All owner-suspected laminitis cases were confirmed

Proportional-integral control modes for a hydrogen isotope distillation column

International Nuclear Information System (INIS)

Kinoshita, M.; Bartlit, J.R.; Sherman, R.H.

1984-01-01

The dynamics and control of a hydrogen isotope distillation column are discussed. The proportionalintegral (PI) controller parameter setting method previously reported by one of the authors is further investigated and extended by applying the method to two different experimental control modes. The method accounts for the nonlinearity of the column to some extent and allows us to predict the unstable region or the region of the proportional-only control behavior. The method can also be applied to the cases where the measurement of the controlled variable is accompanied by a significant time lag. The mean delay time depends greatly on the controlled variable and manipulated variable chosen and the upset condition assumed, varying by over two orders of magnitude. The PI control presents great stability, and a rather long time lag is permissible in the measurement of the controlled variable if the flow rate of the top product is chosen for the manipulated variable. On the other hand, if the reflux ratio is manipulated for controlling the lightest key element in the bottom product, the great stability is no longer present and the time lag must be adequately short. Once several response curves of the controlled variable are calculated for different magnitudes of the manipulated variable upset, the parameter setting method proposed makes it possible to study how long a time lag is allowable in the measurement of the controlled variable

Pets, Purity and Pollution: Why Conventional Models of Disease Transmission Do Not Work for Pet Rat Owners.

Science.gov (United States)

Robin, Charlotte; Perkins, Elizabeth; Watkins, Francine; Christley, Robert

2017-12-07

In the United Kingdom, following the emergence of Seoul hantavirus in pet rat owners in 2012, public health authorities tried to communicate the risk of this zoonotic disease, but had limited success. To explore this lack of engagement with health advice, we conducted in-depth, semi-structured interviews with pet rat owners and analysed them using a grounded theory approach. The findings from these interviews suggest that rat owners construct their pets as different from wild rats, and by elevating the rat to the status of a pet, the powerful associations that rats have with dirt and disease are removed. Removing the rat from the contaminated outside world moves their pet rat from being 'out of place' to 'in place'. A concept of 'bounded purity' keeps the rat protected within the home, allowing owners to interact with their pet, safe in the knowledge that it is clean and disease-free. Additionally, owners constructed a 'hierarchy of purity' for their pets, and it is on this structure of disease and risk that owners base their behaviour, not conventional biomedical models of disease.

Analysis of Urban Car Owners Commute Mode Choice Based on Evolutionary Game Model

Directory of Open Access Journals (Sweden)

Huawei Gong

2015-01-01

Full Text Available With the aggravation of the traffic congestion in the city, car owners will have to give up commuting with private cars and take the public transportation instead. The paper uses the replication dynamic mechanism to simulate the learning and adjustment mechanism of the automobile owners commuting mode selection. The evolutionary stable strategy is used to describe the long-term evolution of competition game trend. Finally we simulate equilibrium and stability of an evolution of the game under a payoff imbalance situation. The research shows that a certain proportion of car owners will choose public transit under the pressure of public transport development and heavy traffic, and the proportion will be closely related to the initial conditions and urban transportation development policy.

Study of the controllable reactivity of aluminum alloys and their promising application for hydrogen generation

International Nuclear Information System (INIS)

Fan Meiqiang; Sun Lixian; Xu Fen

2010-01-01

The hydrolysis performances of two aluminum alloys are investigated as their reactivity can be controlled via the different additives. The additive of NaCl has the positive effect to improve the hydrolysis properties of the aluminum alloys with quicker hydrolysis kinetic and lower hydrolysis temperature. For examples, in 6 min of hydrolysis reaction, the Al-5 wt%Hg-5 wt%NaCl can produce 971 mL g -1 hydrogen, higher than 917 mL g -1 hydrogen from Al-10 wt%Hg alloy. The Al-In-NaCl alloy has lower hydrolysis temperature about 10 K than that of Al-In alloy. Meanwhile, the reactivity of Al alloys can be improved or reduced via the additive metals. It can be found that the additive cadmium can reduce the reactivity of Al-Hg alloy. The Al-Hg-Cd alloys can keep good stability at the moist atmosphere below 343 K and have excellent hydrolysis performance around 343-373 K. The debased reactivity of Al-Hg-Cd composite comes from the formation of CdHg 2 compounds in the milling process. But the additive Zn and Ga doped into the Al-In-NaCl alloys can quickly increase the reactivity of the alloy which can quickly react with water at room temperature and have high hydrogen yield up to the theoretic value. Therefore, it is a promising possibility that the controllable reactivity of aluminum alloys can be obtained through the different additive according to the practical request, and the Al alloys can produce pure hydrogen for the fuel cell via the hydrolysis reaction.

Hydrogen in oxygen-free, phosphorus-doped copper-Charging techniques, hydrogen contents and modelling of hydrogen diffusion and depth profile

Martinsson, Aasa; Sandstroem, Rolf; Lilja, Christina

2013-01-01

In Sweden spent nuclear fuel is planned to be disposed of by encapsulating in cast iron inserts protected by a copper shell. The copper can be exposed to hydrogen released during corrosion processes in the inserts. If the hydrogen is taken up by the copper, it could lead to hydrogen embrittlement. Specimens from oxygen-free copper have been hydrogen charged using two different methods. The purpose was to investigate how hydrogen could be introduced into copper in a controlled way. The thermal charging method resulted in a reduction of the initial hydrogen content. After electrochemical charging of cylindrical specimens, the measured hydrogen content was 2.6 wt. ppm which should compared with 0.6 wt. ppm before charging. The retained hydrogen after two weeks was reduced by nearly 40%. Recently the paper 'Hydrogen depth profile in phosphorus-doped, oxygen-free copper after cathodic charging' (Martinsson and Sandstrom, 2012) has been published. The paper describes experimental results for bulk specimens as well as presenting a model. Almost all the hydrogen is found to be located less than 100 μm from the surface. This model is used to interpret the experimental results on foils in the present report. Since the model is fully based on fundamental equations, it can be used to analyse what happens in new situations. In this report the effect of the charging intensity, the grain size, the critical nucleus size for hydrogen bubble formation as well as the charging time are analysed

The existence of parenting styles in the owner-dog relationship.

Full Text Available Parents interact with children following specific styles, known to influence child development. These styles represent variations in the dimensions of demandingness and responsiveness, resulting in authoritarian, authoritative, permissive or uninvolved parenting. Given the similarities in the parent to child and owner to dog relationships, we determined the extent to which parenting styles exist in the owner to dog relationship using the existing Parenting Styles and Dimensions Questionnaire for the parent-child relationship and an adapted version for dog owners. Items on the parenting of children/dogs were rated for applicability on a five-point Likert scale by 518 Dutch dog owning parents. Principal Component Analyses grouped parenting propensities into styles, with some marked differences between the findings for children and dogs. Dog-directed items grouped into an authoritarian-correction orientated style, incorporating variation in demandingness and focussing on correcting a dog for behaviour verbally/physically, and in two styles based on authoritative items. An authoritative-intrinsic value orientated style reflected variation in mainly responsiveness and oriented on the assumed needs and emotions of the animal. A second authoritative-item based style, captured variations in demandingness and responsiveness. We labelled this style authoritative-training orientated, as it orientated on manners in teaching a dog how to behave in social situations. Thus, we defined dog-directed parenting styles and constructed a Dog-Directed Parenting Styles and Dimensions Questionnaire along the lines of the existing theoretical framework on parenting styles. We did not find a dog-directed parenting style of being permissive or uninvolved, which we attribute to a study population of devoted dog owners and our findings should be interpreted with this specific study population in mind.

Nabarlek Traditional Owners' perspective on the current state of revegetation

International Nuclear Information System (INIS)

Lewis, B.

2001-01-01

Aboriginal people derive their identity from an ancestral relationship to land mediated through a traditional form of land title. This relationship to country determines a group or individual's place in the complex of law, ceremony, culture, responsibility, status, marriage, income etc (often collectively termed 'culture'), that is the essential corollary of traditional land tenure. In effect, country bestows upon Traditional Owners a place in the scheme of things as do social and occupational status, racial origin, financial position etc upon the Westerner. It is a critical link in the preservation of Aboriginal society, and pressure on or erosion of this relationship imposes further strain on the significant burden to Traditional Owners of cultural maintenance. In order that disenfranchisement does not occur because of the mining process, Traditional Owners must have a guarantee that the country will be returned to a pre-mining state as far as possible. This is certainly a significant part of the initial discussion of any consent (under the Aboriginal Land Rights (Northern Territory) Act, 1976). Among the worst outcomes for Aboriginal people involved in the mining process is the return to them of degraded lands, an indication to them that the Westerners who initially placed such great value on it no longer do so. These people are left with the mess or the scraps and perhaps for them the least traumatic course is to walk away, to pretend that the mined-out country is of no importance to them and that there is no pain. The rehabilitation of Nabarlek is in some ways a special case. There was a fairly long period from 1988 to 1994 in which nothing happened. At the final decision to close the operation much of the infrastructure was no longer useable. Initially there was ascribed certain value to plant and equipment items that did not really eventuate for Traditional Owners. Significant portions of the remnant infrastructure was handed back to Traditional Owners

Forest Owners' Response to Climate Change: University Education Trumps Value Profile.

Science.gov (United States)

Blennow, Kristina; Persson, Johannes; Persson, Erik; Hanewinkel, Marc

2016-01-01

Do forest owners' levels of education or value profiles explain their responses to climate change? The cultural cognition thesis (CCT) has cast serious doubt on the familiar and often criticized "knowledge deficit" model, which says that laypeople are less concerned about climate change because they lack scientific knowledge. Advocates of CCT maintain that citizens with the highest degrees of scientific literacy and numeracy are not the most concerned about climate change. Rather, this is the group in which cultural polarization is greatest, and thus individuals with more limited scientific literacy and numeracy are more concerned about climate change under certain circumstances than those with higher scientific literacy and numeracy. The CCT predicts that cultural and other values will trump the positive effects of education on some forest owners' attitudes to climate change. Here, using survey data collected in 2010 from 766 private forest owners in Sweden and Germany, we provide the first evidence that perceptions of climate change risk are uncorrelated with, or sometimes positively correlated with, education level and can be explained without reference to cultural or other values. We conclude that the recent claim that advanced scientific literacy and numeracy polarizes perceptions of climate change risk is unsupported by the forest owner data. In neither of the two countries was university education found to reduce the perception of risk from climate change. Indeed in most cases university education increased the perception of risk. Even more importantly, the effect of university education was not dependent on the individuals' value profile.

Here, using survey data collected in 2010 from 766 private forest owners in Sweden and Germany, we provide the first evidence that perceptions of climate change risk are uncorrelated with, or sometimes positively correlated with, education level and can be explained without reference to cultural or other values. We conclude that the recent claim that advanced scientific literacy and numeracy polarizes perceptions of climate change risk is unsupported by the forest owner data. In neither of the two countries was university education found to reduce the perception of risk from climate change. Indeed in most cases university education increased the perception of risk. Even more importantly, the effect of university education was not dependent on the individuals' value profile.

On the brink: how business owners experience business-related and other legal problems

OpenAIRE

Balmer, N. J.; Pleasence, P.

Nanodiamond for hydrogen storage: temperature-dependent hydrogenation and charge-induced dehydrogenation.

Science.gov (United States)

Lai, Lin; Barnard, Amanda S

2012-02-21

Carbon-based hydrogen storage materials are one of hottest research topics in materials science. Although the majority of studies focus on highly porous loosely bound systems, these systems have various limitations including use at elevated temperature. Here we propose, based on computer simulations, that diamond nanoparticles may provide a new promising high temperature candidate with a moderate storage capacity, but good potential for recyclability. The hydrogenation of nanodiamonds is found to be easily achieved, in agreement with experiments, though we find the stability of hydrogenation is dependent on the morphology of nanodiamonds and surrounding environment. Hydrogenation is thermodynamically favourable even at high temperature in pure hydrogen, ammonia, and methane gas reservoirs, whereas water vapour can help to reduce the energy barrier for desorption. The greatest challenge in using this material is the breaking of the strong covalent C-H bonds, and we have identified that the spontaneous release of atomic hydrogen may be achieved through charging of hydrogenated nanodiamonds. If the degree of induced charge is properly controlled, the integrity of the host nanodiamond is maintained, which indicates that an efficient and recyclable approach for hydrogen release may be possible.

2009-01-01

It is commonly argued that high tax rates motivate individuals to start a business as it is easier to avoid and evade taxes if self-employed compared to employed. If this is the case we would expect small business owners to be more responsive to tax rate changes than employees. This study investigates how responsive existing small business owners are to tax rate changes by estimating the elasticities of taxable income, gross income and reported income from business ventures for small business...

Initiating nuclear power programmes: Responsibilities and capabilities of owners and operators

International Nuclear Information System (INIS)

2009-01-01

There is an increasing interest in developing nuclear power due to growing energy needs, limitations on natural resources and concern for the environment. However, the introduction and development of nuclear power is a major undertaking. This requires building the necessary national infrastructure to construct and operate nuclear power plants in a safe, secure and technically sound manner. Many IAEA Member States that do not yet have nuclear power programmes have expressed their interest to the IAEA about the possibility of introducing nuclear power plants to help meet their energy needs. To assist these Member States, the IAEA is preparing a series of guides and reports. An overall description of the issues was presented by the IAEA in a brochure entitled Considerations to Launch a Nuclear Power Programme (GOV/INF/2007/2), which was targeted mainly at policy makers. A subsequent IAEA Nuclear Energy Series publication, Milestones in the Development of a National Infrastructure for Nuclear Power (NG-G-3.1), describes 19 infrastructure issues that should be addressed through the three phases of development outlined in the brochure, Considerations to Launch a Nuclear Power Programme. The IAEA is preparing a number of guides addressing these issues. Once a firm decision has been made by a government to proceed with the development of a nuclear programme, a number of organizations must be developed. A key organization for the successful construction and operation of the first nuclear power plant is the owner/operator, who provides ownership and management of the project. The owner/operator must clearly understand what must be done and how it has to act, who are partners and supporters and the corresponding interactions that have to be established. The owner or operator may be state owned or a private company. It may be an existing utility, or a specially established project organization. Its responsibilities include bidding, construction, licensing, commissioning

This retrospective study was undertaken to estimate i) the surveillance coverage for equine infectious anemia (EIA) based on owner-requested testing, and ii) the incidence of case detection from this surveillance activity to inform a review of Canada's national disease control strategy. Based on sample submissions by accredited veterinarians to laboratories CFIA-approved for EIA testing between 2009 and 2012, the estimated national surveillance coverage was 14% for all years, and 72 cases of EIA were detected. The annual national incidence of EIA detection ranged from 0.03 to 0.08 cases/1000 horses. On average, a greater proportion of the horse population was tested in eastern Canada (32%) than in western Canada (6%, P Canada (0.25 cases/1000 horses) than in eastern Canada (0.02 cases/1000 horses, P < 0.0001). This study identified regional differences in owner-requested EIA testing and case detection resulting from this testing activity.

A Decision Model Assessing the Owner and Contractor’s Conflict Behaviors in Construction Projects

Directory of Open Access Journals (Sweden)

Guangdong Wu

2018-01-01

Full Text Available Considering the effects of the contractor’s conflict behaviors on the project benefit, a decision model between the owner and contractor’s conflict behaviors in construction projects was constructed using the principal-agent theory and game theory. The model was analyzed under nonconflicting and conflicting conditions, and a numerical simulation and example analysis were proposed to verify the constructed model’s conclusion. The results showed that the effort levels of the owner and contractor not only relate to benefit-sharing coefficient and effort outcome coefficient but also depend on the contractor’s ability of converting the conflict into benefit and the loss caused by conflict behaviors. A higher ability of converting conflicts into benefits and lower levels of the loss caused by conflict behaviors for the contractor lead to lower levels of the net benefit of the owner, conversely higher levels of the net benefit of the contractor. Balancing the contractor’s ability of converting conflicts into benefits and the loss caused by conflict behaviors lead to a more reasonable risk allocation between the owner and contractor, improving the effort level and net benefit. To add value to the construction project, the owner should establish an impartial and reasonable benefit-sharing mechanism, optimize the owner and contractor’s resource arrangement, maximize the positive effect of conflict on project benefits, and avoid the negative effect of conflict. Few studies to date have investigated the effects of conflict behaviors on project benefits in terms of modeling and simulation in construction projects. As such, this study bridges this gap and contributes significant theoretical and practical insights about managing conflict behaviors in an interorganizational context, thus enhancing performance in construction projects.

become worried that they would run out of fuel before encountering a facility, their motivation to purchase a hydrogen-powered vehicle decreases. At vehicle purchase time, they weigh this experience, as well as other factors such as social influence by their peers, fuel cost, and capital cost of a hydrogen vehicle. Investor agents build full-service hydrogen fueling stations (HFSs) at different locations along the highway network. They base their decision to build or not build a station on their (imperfect) estimates of the sales the station would immediately generate (based on hydrogen-powered vehicle traffic past the location and other factors), as well as the growth in hydrogen sales they could expect throughout their investment horizon. The interaction between driver and investor agents provides the basis for growth in both the number of hydrogen vehicles and number of hydrogen stations. For the present report, we have added to this mix smaller, 'bare-bones' hydrogen dispensing facilities (HDFs) of the type that owners of CHHP facilities could provide to the public. The locations of these stations were chosen to match existing facilities that might reasonably incorporate CHHP plants in the future. Unlike the larger commercial stations, these facilities are built according to exogenously supplied timetables, and no attempt has been made to model the financial basis for the facilities. Rather, our objective is to understand how the presence of these additional stations might facilitate the petroleum-to-hydrogen transition. We discuss a base case in which the HDFs are not present, and then investigate the effects of introducing HDFs in various numbers; according to different timetables; with various production capacities; and with hydrogen selling at prices above, equal to, and below the commercial stations selling price. We conclude that HDFs can indeed be helpful in accelerating a petroleum-to-hydrogen transition. Placed in areas where investors might not be

An optimal hydrogen control analysis for the in-containment refueling storage tank (IRWST) of the Korean next generation reactor (KNGR) containment under severe accidents

Byung-Chul, Lee; Hee-Jin, Ko; Se-Won, Lee

Under severe accidents that a large amount of hydrogen is expected to release, the In-Containment Refueling Water Storage Tank (IRWST) air space has more worse condition with respect to the hydrogen control since, as one of hydrogen source compartment, normally it is separated from the other compartments and has relatively small volume. The hydrogen concentrations in the IRWST gas space, when the hydrogen was directly released into this area, were analyzed using the MAAP4 code in order to investigate if locally very high concentrations could be reduced so that inadvertent detonation or detonation-to-deflagration (DDT) in this area might be prevented. For this purpose, the thermo-hydraulic and combustion phenomena being capable of occurring in the IRWST were also considered. As a result of numerical calculations with 12-compartment containment model, the time duration that the flammable gas mixture was formed was greatly decreased via oxygen-starved or steam-rich conditions, although instantaneously peak concentration itself could not be avoided. Moreover, if the diffusion flame or steam stripping can be occurred in the IRWST, it was expected to have more chance to control the hydrogen in the IRWST gas space. After the hydrogen finished to be rapidly released, the hydrogen in this area could be controlled by the PARs' hydrogen depletion and by igniter's deliberate burning. Especially, the review on the analyses for two typical, but most probable sequences of quite a different hydrogen release modes gives an insight that the flammable gas mixture in the IRWST can be avoid by rapid depressurization operation, which is recommendable for being implemented into accident management program.

Oxytocin and Cortisol Levels in Dog Owners and Their Dogs Are Associated with Behavioral Patterns: An Exploratory Study

Directory of Open Access Journals (Sweden)

Maria Petersson

2017-10-01

Full Text Available We have previously shown that dog–owner interaction results in increasing oxytocin levels in owners and dogs, decreasing cortisol levels in owners but increasing cortisol levels in dogs. The present study aimed to further investigate whether oxytocin and cortisol levels in the previously tested owners and dogs were associated with their behaviors during the interaction experiment. Ten female volunteer dog–owners and their male Labrador dogs participated in a 60 min interaction experiment with interaction taking place during 0–3 min and blood samples for analysis of oxytocin and cortisol were collected at 0, 1, 3, 5, 15, 30, and 60 min. The entire experiment was videotaped and the following variables were noted; the different types (stroking, scratching, patting and activating touch, i.e., scratching and patting combined as well as the frequency of touch applied by the owner, the number of times the owner touched her dog, the dog’s positions and time spent in each position. Correlations were analyzed between the behavioral variables and basal oxytocin levels, maximum oxytocin levels, delta oxytocin levels, basal cortisol levels and cortisol levels at 15 min. Owners with low oxytocin levels before and during the interaction touched their dogs more frequently (0 min: Rs = -0.683, p = 0.042; oxytocin maximum: Rs = -0.783, p = 0.013. The lower the dogs’ oxytocin levels during the interaction, the more stroking they received (Rs = -0.717, p = 0.041. The more frequently activating touch was applied by the owner, the higher the dogs’ cortisol levels became (15 min: Rs = 0.661, p = 0.038. The higher the owners’ maximum oxytocin level the fewer position changes the dogs made (Rs = -0.817, p = 0.007 and the shorter time they spent sitting (Rs = -0.786, p = 0.036, whereas the higher the owners’ basal cortisol levels, the longer time the dogs spent standing (0 min: Rs = 0.683, p = 0.041. In conclusion, oxytocin and cortisol levels, both in

A growing number of early discovery collaborative agreements are being put in place between large pharma companies and partners in which the rights for assets can reside with a partner, exclusively or jointly. Our corporate screening collection, like many others, was built on the premise that compounds generated in-house and not the subject of paper or patent disclosure were proprietary to the company. Collaborative screening arrangements and medicinal chemistry now make the origin, ownership rights and usage of compounds difficult to determine and manage. The Compound Passport Service is a dynamic database, managed and accessed through a set of reusable services that borrows from social media concepts to allow sample owners to take control of their samples in a much more active way.

A qualitative evaluation of owner and worker health and safety beliefs in small auto collision repair shops.

Science.gov (United States)

Parker, David L; Bejan, Anca; Brosseau, Lisa M

2012-05-01

About 223,000 people are employed in approximately 34,500 auto collision repair businesses. In general, employees and owners in these establishments lack knowledge of health and safety practices and do not have the technical expertise to make their place of work safer. Three employee and three owner focus groups were conducted. The goal of these focus groups was to characterize health and safety beliefs of owners and employees and to determine the best methods for motivating safety improvements in collision repair shops. A total of 11 owners and 19 workers participated in these focus groups. Employees and owners were aware of a wide range of hazards. Both groups noted difficulty in staying informed. Employers were hesitant to set and enforce safety and health rules. Employees perceive owners to be unwilling to dedicate the resources to make the workplace safer and provide personal protective equipment. Both groups felt insurance reimbursement practices placed undue pressure on employees. Focus groups provide important insights into intervention development in very small enterprises in general and auto collision shops in specific. Employers were conflicted about allowing employees a certain level of independence while also maintaining a safe workplace. From the employee perspective, owners frequently fail to provide adequate personal protective equipment and make improvements needed to ensure safe work. The unique managerial needs of very small enterprises must be accounted for if health and safety programs are to be implemented in these establishments. Copyright © 2012 Wiley Periodicals, Inc.

Resorts, second home owners and distance: a case study in northern Finland

Directory of Open Access Journals (Sweden)

Pekka Kauppila

2010-11-01

Full Text Available One of the most important factors for the site selection of a second home is the space-time dimension. For example, the popularity of second home tourism in the hinterland of population centres is based on the short distance between second homes and the permanent residence of second home owners. In the case of peripheral resorts, however, the main reason for a large number of second homes is the attractiveness of the area associated with a high level of touristic elements. The study examines the municipalities of residence of the second home owners in four large resorts – Levi, Ruka, Saariselkä and Ylläs – in northern Finland. After analysing the geographical distribution of the owners with maps and diagrams the aim of the paper is to present a distance model for the resorts located in a northern periphery from the viewpoint of the regions of destination. Generally speaking, the model resembles a U-letter. In this respect, the resorts have three zones – day trip, weekend and vacation – and each of them has their own characteristics based on accessibility and regional structure, the number and structure of population (potential owners and land ownership. In the planning context, the proposed model can be utilised as a tool for the marketing of resorts as a second home environment as well as for analysing and comparing the overall attractiveness of resorts.

Merola, Isabella; Prato-Previde, Emanuela; Marshall-Pescini, Sarah

2012-01-01

Social referencing is a process whereby an individual uses the emotional information provided by an informant about a novel object/stimulus to guide his/her own future behaviour towards it. In this study adult dogs were tested in a social referencing paradigm involving a potentially scary object with either their owner or a stranger acting as the informant and delivering either a positive or negative emotional message. The aim was to evaluate the influence of the informant's identity on the dogs' referential looking behaviour and behavioural regulation when the message was delivered using only vocal and facial emotional expressions. Results show that most dogs looked referentially at the informant, regardless of his/her identity. Furthermore, when the owner acted as the informant dogs that received a positive emotional message changed their behaviour, looking at him/her more often and spending more time approaching the object and close to it; conversely, dogs that were given a negative message took longer to approach the object and to interact with it. Fewer differences in the dog's behaviour emerged when the informant was the stranger, suggesting that the dog-informant relationship may influence the dog's behavioural regulation. Results are discussed in relation to studies on human-dog communication, attachment, mood modification and joint attention.

Dogs' social referencing towards owners and strangers.

Directory of Open Access Journals (Sweden)

Isabella Merola

Full Text Available Social referencing is a process whereby an individual uses the emotional information provided by an informant about a novel object/stimulus to guide his/her own future behaviour towards it. In this study adult dogs were tested in a social referencing paradigm involving a potentially scary object with either their owner or a stranger acting as the informant and delivering either a positive or negative emotional message. The aim was to evaluate the influence of the informant's identity on the dogs' referential looking behaviour and behavioural regulation when the message was delivered using only vocal and facial emotional expressions. Results show that most dogs looked referentially at the informant, regardless of his/her identity. Furthermore, when the owner acted as the informant dogs that received a positive emotional message changed their behaviour, looking at him/her more often and spending more time approaching the object and close to it; conversely, dogs that were given a negative message took longer to approach the object and to interact with it. Fewer differences in the dog's behaviour emerged when the informant was the stranger, suggesting that the dog-informant relationship may influence the dog's behavioural regulation.

Factors influencing German house owners' preferences on energy retrofits

International Nuclear Information System (INIS)

Achtnicht, Martin; Madlener, Reinhard

2014-01-01

In this paper, we identify key drivers and barriers for the adoption of building energy retrofits in Germany, which is promoted by public policy as an important measure to address the future challenges of climate change and energy security. We analyze data from a 2009 survey of more than 400 owner-occupiers of single-family detached, semidetached, and row houses in Germany, that was conducted as a computer-assisted personal interview (CAPI). In the survey, respondents were asked directly for reasons for and against retrofitting their homes, but also faced a choice experiment involving different energy retrofit measures. Overall, we find that house owners who are able to afford it financially, for whom it is profitable, and for whom there is a favorable opportunity are more likely to undertake energy retrofit activities. The latter point seems to be of particular importance in explaining the persistent low retrofit rate in Germany. Our results suggest that professional energy advice could stimulate the demand for building energy retrofits. - Highlights: • Survey data of 400 owner-occupiers from Germany is analyzed. • Drivers and barriers for the adoption of building energy retrofits are identified. • Descriptive and econometric results underline the importance of economic factors. • The simulated incentive effect of expert recommendations is notable in magnitude. • Professional energy advice thus may help to stimulate energy retrofit activities

Forest owner representation of forest management and perception of resource efficiency: a structural equation modeling study

Directory of Open Access Journals (Sweden)

Andrej Ficko

2015-03-01

Full Text Available Underuse of nonindustrial private forests in developed countries has been interpreted mostly as a consequence of the prevailing noncommodity objectives of their owners. Recent empirical studies have indicated a correlation between the harvesting behavior of forest owners and the specific conceptualization of appropriate forest management described as "nonintervention" or "hands-off" management. We aimed to fill the huge gap in knowledge of social representations of forest management in Europe and are the first to be so rigorous in eliciting forest owner representations in Europe. We conducted 3099 telephone interviews with randomly selected forest owners in Slovenia, asking them whether they thought they managed their forest efficiently, what the possible reasons for underuse were, and what they understood by forest management. Building on social representations theory and applying a series of structural equation models, we tested the existence of three latent constructs of forest management and estimated whether and how much these constructs correlated to the perception of resource efficiency. Forest owners conceptualized forest management as a mixture of maintenance and ecosystem-centered and economics-centered management. None of the representations had a strong association with the perception of resource efficiency, nor could it be considered a factor preventing forest owners from cutting more. The underuse of wood resources was mostly because of biophysical constraints in the environment and not a deep-seated philosophical objection to harvesting. The difference between our findings and other empirical studies is primarily explained by historical differences in forestland ownership in different parts of Europe and the United States, the rising number of nonresidential owners, alternative lifestyle, and environmental protectionism, but also as a consequence of our high methodological rigor in testing the relationships between the constructs

Nonprofit equine rescue organizations in the United States provide care for relinquished horses and may offer adoption programs. With an estimated 100,000 "unwanted" horses per year and few municipal shelters providing wholesale euthanasia, there is a need to minimize the number of unwanted horses and maximize their successful transition to new caregivers. This study's objectives were to characterize the relinquishing and adoptive owners interacting with nonprofit rescue organizations. Nonprofit organizations (n = 144) in 37 states provided information by survey on 280 horses relinquished between 2006 and 2009, from which 73 were adopted. Results show the majority of relinquishing owners were women, whereas adoptive owners were primarily families or couples. Most relinquishing owners had previous equine experience and had owned the horse for 1 to 5 years; about half owned 1 other horse. Three quarters of the adoptive owners possessed additional horses housed on their property. The primary use for rehomed horses was for riding or driving. These findings will serve to help develop effective education programs for responsible horse ownership and optimize acceptance criteria and successful adoption strategies of horses by nonprofit organizations.

Tritium/hydrogen barrier development

International Nuclear Information System (INIS)

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

1994-06-01

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

Post-operative complications and owner satisfaction following partial caudectomies: 22 cases (2008 to 2013).

To report complications and owner satisfaction for dogs and cats following partial caudectomy. Medical records of dogs and cats (n = 22) that underwent partial caudectomy between 2008 and 2013 were retrospectively reviewed. Signalment, reason for amputation, level of amputation, and complications were recorded. Owners were contacted via telephone to obtain follow-up data. The most common reason for partial caudectomy was tail wounds (16 of 22; 72 · 7%). Complications were typically minor incisional crusting (4 of 20; 20%). Major complications (3 of 20; 15%) included prolonged healing after partial incisional dehiscence, continued self-trauma requiring revision surgery, and severe inflammation with ulceration requiring revision surgery. The majority of owners surveyed (10 of 12; 83 · 3%) were satisfied with the post-operative outcome and would recommend this procedure if warranted. Partial caudectomy is well tolerated in both dogs and cats with no loss of function. Pet owners did not perceive any behavioural changes following partial caudectomy. However, in cases of continued self-mutilation and/or incisional dehiscence, revision procedures may be required. © 2014 British Small Animal Veterinary Association.

Prevalence of periodontal disease in dogs and owners' level of awareness - a prospective clinical trial

Natalia Alves Fernandes

2012-08-01

Full Text Available Periodontal disease (PD is widely known among veterinarians for its high prevalence and serious consequences to the dogs. The objective of this study was to assess the occurrence of PD in dogs that live in the micro-region of Viçosa, treated at the Veterinary Hospital of the Federal University of Viçosa (HVT - Hospital Veterinário da Universidade Federal de Viçosa, as well as to assess how aware of this disease dog owners are. In order to do so, all dogs treated at the HVT from March 10th, 2009 to November 30th, 2009, on alternate days, had their oral cavities examined. Medical history data, such as age, type of food, main complaint and owner consent, halitosis, presence of dental calculus, inflammation and gingival recession and tooth loss, were collected. A prevalence of 88.67% was found for PD in dogs referred to the HVT, and 2.67% were referred due to this disease. Of all the owners who participated in the study, 43.83% knew about periodontal disease and of these 17.46% made use of some type of prevention or treatment. Therefore, periodontal disease is highly prevalent and the owners are not aware of the disease. Thus, a dog owner clarification program on periodontal disease is needed in the area where HVT-UFV operates.

Understanding individual behavioral differences in domestic cats could lead to improved selection when potential cat owners choose a pet with whom to share their lives, along with consequent improvements in cat welfare. Yet very few attempts have been made to elicit cat personality dimensions using the trait-based exploratory approaches applied previously, with some success, to humans and dogs. In this study, a list of over 200 adjectives used to describe cat personality was assembled. This list was refined by two focus groups. A sample of 416 adult cat owners then rated a cat they knew well on each of 118 retained words. An iterative analytical approach was used to identify 29 words which formed six personality dimensions: Playfulness, Nervousness, Amiability, Dominance, Demandingness, and Gullibility. Chronbach's alpha scores for these dimensions ranged from 0.63 to 0.8 and, together, they explained 56.08% of the total variance. Very few significant correlations were found between participant scores on the personality dimensions and descriptive variables such as owner age, cat age and owner cat-owning experience, and these were all weak to barely moderate in strength (r≤0.30). There was also only one significant group difference based on cat sex. Importantly, however, several cat personality scores were moderately (r=0.3-0.49) or strongly (r≥0.5) correlated with simple measures of satisfaction with the cat, attachment, bond quality, and the extent to which the cat was perceived to be troublesome. The results suggest that, with further validation, this scale could be used to provide a simple, tick-box, assessment of an owner's perceptions regarding a cat's personality. This may be of value in both applied and research settings. Copyright © 2017 Elsevier B.V. All rights reserved.

2015-01-01

The loss of a pet may be stressful to the owner. The main objectives of this study were to compare the levels of stress and to explore the correlates of QOL of healthy adults who currently own or who have just lost their dog. The study sample contained 110 current, and 103 bereaved dog owners, all females, who lost their dogs due to euthanasia. QOL was assessed with the WHOQOL-BREF questionnaire and divided into four major domains-Physical, Psychological, Relationship, and Environmental. Demographic variables, stress, health behaviors, and social support from family, friends, and significant other were included in multivariate analysis. Stress levels were significantly higher in bereaved owners. QOL in three of the four domains (Physical, Psychological, and Relationship) of current owners were significantly better than among bereaved owners. Stress was significantly associated with these three domains of QOL. Quality of life was found to be positively associated with social support. Age was related directly only to current owners' QOL. The results suggest that a loss of a dog is associated with stress for the bereaved owner and reduced physical, psychological, and relationship QOL. Lack of social support in the case of death of a companion animal has a strong effect on owners' grief reactions.

McKay, Stacey A; Farnworth, Mark J; Waran, Natalie K

2009-01-01

This study distributed a questionnaire to cat or dog caregivers (owners) throughout Auckland, New Zealand, to investigate the attitudes of human companions toward the sterilization of their cats and dogs and the degree to which this occurs relative to demographic information gathered. A total of 276 recipients returned questionnaires with data pertinent to 477 cats and dogs. Female owners were more likely than were males to sterilize cats or dogs: 90.2% sterilization rate compared with 80%. Statistical trends also suggested that owners with a postschool education had a higher percentage of sterilized nonhuman animals than owners with no postschool or only school-age education. Cats were more likely than dogs to be neutered: 91.7% versus 78.5%. Companion animals not annually vaccinated were more likely to be sterilized than animals who were vaccinated annually: 93.6% and 85.4%. The study also showed gender bias and age differences in owner attitudes toward a number of the statements regarding sterilization, with male owners more likely to be concerned about the effect of neutering or spaying on the sexuality or masculinity of the animal.

ONODERA, Nodoka; UCHIDA, Keiko; KAKUMA, Yoshie

2014-01-01

ABSTRACT A follow-up questionnaire survey was conducted with 29 cat owners who adopted cats from an animal hospital in Japan. Physical characteristics were found to be important factors for the owners when choosing a cat. There were significant differences between impression of the cat for the owners at present and images of their ideal cats, and the levels of aggression and activeness of the cats at present were rated higher than their ideal cats. A significant negative correlation was found between the degree of satisfaction with the cat and occurrence of house soiling; thus, some behavioral problems may deteriorate the relationship between the owner and the cat.

Playing with fire - What is influencing horse owners' decisions to not vaccinate their horses against deadly Hendra virus infection?

Directory of Open Access Journals (Sweden)

Kailiea Arianna Goyen

Full Text Available Hendra virus is a zoonotic paramyxovirus, which causes severe respiratory and neurological disease in horses and humans. Since 2012, the Hendra virus sub-unit G vaccine has been available for horse vaccination in Australia. Uptake of the vaccine has been limited and spill-over events of Hendra virus infection in horses continue to occur. We conducted an online, questionnaire-based cross-sectional study of 376 horse owners belonging to a variety of different equestrian clubs in Queensland, Australia, to identify risk factors for non-vaccination against Hendra virus. A total of 43.1% (N = 162 of horse owners indicated that they currently did not vaccinate against Hendra virus infection, while 56.9% (N = 214 currently vaccinated against Hendra virus infection. A total of 52 risk factors were evaluated relating to equestrian activities, horse management, perceived risk and severity of horse and human infection with Hendra virus, side effects of Hendra vaccination, other vaccinations conducted by horse owners and horse owners' attitudes towards veterinarians. The final multivariable logistics regression model identified the following risk factors associated with increased odds of non-vaccination against Hendra virus: 1 perceived low risk (compared to high of Hendra virus infection to horses (considering the horse owners' location and management practices or horse owners were unsure about the risk of infection, 2 perceived moderate severity (compared to very severe or severe of Hendra virus infection in humans, 3 horse owners non-vaccination of their pets, 4 horse owners non-vaccination against strangles disease in horses, 5 handling of more than three horses per week (compared to one horse only and 6 perceived attitude that veterinarians had a high motivation of making money from Hendra virus vaccination (compared to veterinarians having a low motivation of making money from Hendra virus vaccination.

Full Text Available South African entrepreneurs have a poor skills record, which often leads to business failure. To effectively manage a spaza shop requires applying management functions and some management skills. The implementation of simple systems can assist spaza shop owners to manage their businesses more successfully and even grow. A quantitative study was done, by interviewing sixty spaza shop owners in the township. The empirical results identified the gaps in the management abilities of spaza shop owners in terms of the eight management functions and show that the purchasing, financial and information management function is the most neglected. Guidelines on how each of the functions could or should be applied are given. This research clearly indicates that spaza shops can assist in economic growth and relieve unemployment in the country.

2009-03-02

Platinum nanocubes and nanopolyhedra with tunable size from 5 to 9 nm were synthesized by controlling the reducing rate of metal precursor ions in a one-pot polyol synthesis. A two-stage process is proposed for the simultaneous control of size and shape. In the first stage, the oxidation state of the metal ion precursors determined the nucleation rate and consequently the number of nuclei. The reaction temperature controlled the shape in the second stage by regulation of the growth kinetics. These well-defined nanocrystals were loaded into MCF-17 mesoporous silica for examination of catalytic properties. Pt loadings and dispersions of the supported catalysts were determined by elemental analysis (ICP-MS) and H2 chemisorption isotherms, respectively. Ethylene hydrogenation rates over the Pt nanocrystals were independent of both size and shape and comparable to Pt single crystals. For pyrrole hydrogenation, the nanocubes enhanced ring-opening ability and thus showed a higher selectivity to n-butylamine as compared to nanopolyhedra.

Stephan P van der Merwe

2011-08-01

Full Text Available The primary objective of this study was to analyse small business owner-managers’ perceptions of entrepreneurship and their motives to start their businesses in the Emfuleni district in South Africa. A total of 307 useable questionnaires were gathered and utilised for the statistical analysis. There were three statements that small business owner-managers perceived to be most applicable to them, i.e. entrepreneurs work longer hours and harder than managers in large companies; money is the most important start-up ingredient; and entrepreneurs experience a great deal of stress and as a consequence pay a high price of their health. With regard to the entrepreneurial motives, an Oblimin oblique rotation was performed on the principal components of the exploratory factor analysis. Two factors with eigenvalues greater than one were extracted describing the theoretical dimensions of the entrepreneurial motive and the non-entrepreneurial motive. The owner-managers indicated that the entrepreneurial motives, to have more satisfaction in work, to be independent, and to use own creative skills, were the most important motives for them venturing into entrepreneurship. No practically significant relationship could be found between the extracted factor, the entrepreneurial motive, and the demographical variables in this study. Practical recommendations are offered to entrepreneurs, the government and business educators.

Haiti has historically vaccinated between 100,000 and 300,000 dogs annually against rabies, however national authorities have not been able to reach and maintain the 70% coverage required to eliminate the canine rabies virus variant. Haiti conducts massive dog vaccination campaigns on an annual basis and utilizes both central point and door-to-door methods. These methods require that dog owners are aware of the dates and locations of the campaign. To improve this awareness among dog owners, 600,000 text messages were sent to phones in two Haitian communes (Gonaives and Saint-Marc) to remind dog owners to attend the campaign. Text messages were delivered on the second day and at the mid-point of the campaign. A post-campaign household survey was conducted to assess dog owner's perception of the text messages and the impact on their participation in the vaccination campaign. Overall, 147 of 160 (91.9%) text-receiving dog owners indicated the text was helpful, and 162 of 187 (86.6%) responding dog owners said they would like to receive text reminders during future rabies vaccination campaigns. In areas hosting one-day central point campaigns, dog owners who received the text were 2.0 (95% CI 1.1, 3.6) times more likely to have participated in the campaign (73.1% attendance among those who received the text vs 36.4% among those who did not). In areas incorporating door-to-door vaccination over multiple days there was no significant difference in participation between dog owners who did and did not receive a text. Text message reminders were well-received and significantly improved campaign attendance, indicating that short message service (SMS) alerts may be a successful strategy in low resource areas with large free roaming dog populations.

Intranasal Oxytocin Treatment Increases Eye-Gaze Behavior toward the Owner in Ancient Japanese Dog Breeds

Directory of Open Access Journals (Sweden)

Miho Nagasawa

2017-09-01

Full Text Available Dogs acquired unique cognitive abilities during domestication, which is thought to have contributed to the formation of the human-dog bond. In European breeds, but not in wolves, a dog’s gazing behavior plays an important role in affiliative interactions with humans and stimulates oxytocin secretion in both humans and dogs, which suggests that this interspecies oxytocin and gaze-mediated bonding was also acquired during domestication. In this study, we investigated whether Japanese breeds, which are classified as ancient breeds and are relatively close to wolves genetically, establish a bond with their owners through gazing behavior. The subject dogs were treated with either oxytocin or saline before the starting of the behavioral testing. We also evaluated physiological changes in the owners during mutual gazing by analyzing their heart rate variability (HRV and subsequent urinary oxytocin levels in both dogs and their owners. We found that oxytocin treatment enhanced the gazing behavior of Japanese dogs and increased their owners’ urinary oxytocin levels, as was seen with European breeds; however, the measured durations of skin contact and proximity to their owners were relatively low. In the owners’ HRV readings, inter-beat (R-R intervals (RRI, the standard deviation of normal to normal inter-beat (R-R intervals (SDNN, and the root mean square of successive heartbeat interval differences (RMSSD were lower when the dogs were treated with oxytocin compared with saline. Furthermore, the owners of female dogs showed lower SDNN than the owners of male dogs. These results suggest that the owners of female Japanese dogs exhibit more tension during interactions, and apart from gazing behavior, the dogs may show sex differences in their interactions with humans as well. They also suggest that Japanese dogs use eye-gazing as an attachment behavior toward humans similar to European breeds; however, there is a disparity between the dog sexes when

Controls and diagnostics on a fuseless railgun for solid hydrogen pellet acceleration

International Nuclear Information System (INIS)

King, T.L.; Zhang, J.; Haywood, R.G.; Manns, W.C.; Kim, K.

1993-01-01

A two-stage railgun system has been built incorporating several controls and diagnostics, some including unique features to account for the fact that the projectile is a frozen hydrogen pellet for fusion reactor refueling. A timing circuit has been developed to monitor projectile breech and muzzle velocities and to automatically trigger a sequence of events critical for effective plasma armature railgun operation. This circuit can initiate electrical breakdown of the propellant gas directly behind an incoming projectile, thus enabling fuseless operation. It also triggers a streak camera and a flashlamp for photographing the arc and the outgoing projectile, respectively. The automatic timing circuit is expandable and has been extended to incorporate a trigger for transaugmentation. The timing circuit is immune to mistriggering due to electromagnetic interference or fragmentation of the fragile hydrogen pellets. Railgun diagnostics also include Pearson coils and B probes for monitoring rail and armature currents, respectively. Laser interferometry and optical spectroscopy are also employed to measure plasma density and temperature. Digitizing oscilloscopes are used to acquire data. The data is transferred to a computer via GPIB

Highlights: • A three-dimensional computational model was built and the applicability was discussed. • The formation of helium stratification was further studied. • Three influencing factors on the post-inerting of hydrogen risk were analyzed. - Abstract: In the case of severe accidents, the risk of hydrogen explosion threatens the integrity of the nuclear reactor containment. According to nuclear regulations, hydrogen control is required to ensure the safe operation of the nuclear reactor. In this study, the method of Computational Fluid Dynamics (CFD) has been applied to analyze process of hydrogen stratification and the post-inerting of hydrogen risk in the Large-Scale Gas Mixing Facility. A three-dimensional computational model was built and the applicability of different turbulence models was discussed. The result shows that the helium concentration calculated by the standard k–ε turbulence model is closest to the experiment data. Through analyzing the formation of helium stratification at different injection velocities, it is found that when the injection mass flow is constant and the injection velocity of helium increases, the mixture of helium and air is enhanced while there is rarely influence on the formation of helium stratification. In addition, the influences of mass flow rate, injection location and direction and inert gas on the post-inerting of hydrogen risk have been analyzed and the results are as follows: with the increasing of mass flow rate, the mitigation effect of nitrogen on hydrogen risk will be further improved; there is an obvious local difference between the mitigation effects of nitrogen on hydrogen risk in different injection directions and locations; when the inert gas is injected at the same mass flow rate, the mitigation effect of steam on hydrogen risk is better than that of nitrogen. This study can provide technical support for the mitigation of hydrogen risk in the small LWR containment.

Gaseous and electrolytic hydrogen charging techniques for introducing controlled amount of hydrogen in zirconium alloy is described. Zr-1wt%Nb fuel tube, zircaloy-2 pressure tube and Zr-2.5Nb pressure tube samples were charged with up to 1000 ppm of hydrogen by weight using one of the aforementioned methods. These hydrogen charged Zr-alloy samples were analyzed for estimating the total hydrogen content using inert gas fusion technique. Influence of sample surface preparation on the estimated hydrogen content is also discussed. In zirconium alloys, hydrogen in excess of the terminal solid solubility precipitates out as brittle hydride phase, which acquire platelet shaped morphology due to its accommodation in the matrix and can make the host matrix brittle. The F N number, which represents susceptibility of Zr-alloy tubes to hydride embrittlement was measured from the metallographs. The volume fraction of the hydride phase, platelet size, distribution, interplatelet spacing and orientation were examined metallographically using samples sliced along the radial-axial and radial-circumferential plane of the tubes. It was observed that hydride platelet length increases with increase in hydrogen content. Considering the metallographs generated by Materials Science Division as standard, metallographs prepared by the IAEA round robin participants for different hydrogen concentration was compared. It is felt that hydride micrographs can be used to estimate not only that approximate hydrogen concentration of the sample but also its size, distribution and orientation which significantly affect the susceptibility to hydride embrittlement of these alloys.

With respect to the conventional nickel-hydrogen secondary battery, pulverization of the hydrogen storage alloy due to repetition of charging-discharging cycles can be prevented by using a fluorocarbon resin as a binder in manufacture of the hydrogen storage alloy electrode; however, the inner pressure increase of the battery in case of overcharging can not be fully controlled. The invention relates to control of the inner pressure increase of the nickel-hydrogen secondary battery in case of overcharging. As to the hydrogen storage alloy electrode, the compound comprising the hydrogen storage alloy powder as a main ingredient is supported by a current collector; further, the compound particularly comprises a fluororubber as a binder. The nickel-hydrogen secondary battery equipped with the hydrogen storage alloy electrode can control the inner pressure increase of the battery in case of overcharging, and lessen decrease of the battery capacity due to repetition of charging-discharging cycles over long time. The effects are dependent on the use of the fluororubber as a binder which has good flexibility, and strong binding capacity as well as water repellency. 1 tab.

Analysis of Differences in the Motivation of the Owner-Managers and Hired Managers of Regional Enterprises

Full Text Available The article deals with the differences in the motivation of owner-managers and hired managers. The purpose of the article is to identify the signs of the differences and similarities in the motivation of hired managers and owner-managers on the basis of the analysis of the results of the study of these issues by other authors, as well as with the help of our research. The hypothesis of the study consists in the assumption that the motivational profile of owner-managers differs from the motivational profile of hired managers in greater riskiness and thrift. The research methodology involves conducting a sociological survey of 100 managers of small and medium-sized enterprises in Kemerovo, half of which are employed and the other half are business owners. Questioning was carried out by several methods: oral, by e-mail, in writing through the Center for Business Support and through other means. The data we processed in the SPSS Statistic program. The results of the study unexpectedly have rejected a basic hypothesis: the average data for the degree of risk and thrift of hired managers is highly competitive with the received indices of owner-managers. There is the only difference in the distribution of characteristics. The level of riskiness and thrift of the hired managers tends to the be average among them and has a slight variation in the estimates, while the owner-managers much differ from each other on these parameters, have a large variation in the values of indicators, show a lot of the diametrically opposed estimates. The study of the motives of of owner-managers activity allows to the authorities to develop recommendations on the improvement of the existing and new programmes for the support of small and medium-sized business; on the formation of executive candidate pool. It also can contribute to revealing the categories of population with expressed entrepreneurial and managerial motivational profiles at a stage of professional education

The J-integral was evaluated as a parameter to characterize fracture of stainless steels and as a measure of hydrogen damage. C-shaped specimens of type 304L, 316, and 21-6-9 stainless steels were tested in high pressure helium and hydrogen. The critical force for crack initiation (Jm), and tearing resistance (dJ/da) were decreased by hydrogen in all three alloys. The J-integral appears useful as a measure of hydrogen compatibility because it is sensitive to both test environment and microstructure

Background Controlled generation and removal of hydrogen peroxide play important roles in cellular redox homeostasis and signaling. We used a hydrogen peroxide biosensor HyPer, targeted to different compartments, to examine these processes in mammalian cells. Principal Findings Reversible responses were observed to various redox perturbations and signaling events. HyPer expressed in HEK 293 cells was found to sense low micromolar levels of hydrogen peroxide. When targeted to various cellular compartments, HyPer occurred in the reduced state in the nucleus, cytosol, peroxisomes, mitochondrial intermembrane space and mitochondrial matrix, but low levels of the oxidized form of the biosensor were also observed in each of these compartments, consistent with a low peroxide tone in mammalian cells. In contrast, HyPer was mostly oxidized in the endoplasmic reticulum. Using this system, we characterized control of hydrogen peroxide in various cell systems, such as cells deficient in thioredoxin reductase, sulfhydryl oxidases or subjected to selenium deficiency. Generation of hydrogen peroxide could also be monitored in various compartments following signaling events. Conclusions We found that HyPer can be used as a valuable tool to monitor hydrogen peroxide generated in different cellular compartments. The data also show that hydrogen peroxide generated in one compartment could translocate to other compartments. Our data provide information on compartmentalization, dynamics and homeostatic control of hydrogen peroxide in mammalian cells. PMID:21283738

2011-01-01

Dogs are highly skilled in understanding a large variety of human social cues and use them appropriately to solve a number of different cognitive tasks. They rely on human signals even when these are contradictory or misleading and ultimately prevent them from correctly solving a task. In the following two experiments, we investigated whether the owner and a stranger differently influenced dogs' choices in food discrimination tasks. In Experiment 1, 48 dogs were tested in 3 different conditions: (1) choice between a large and a small amount of dog pellets with no demonstration; (2) choice between a large and a small amount of dog pellets after having witnessed the owner/stranger favouring the small quantity; (3) choice between two single food pellets after observing the owner/stranger choosing one of them. In Experiment 2, 48 dogs could choose between two foods of different palatability: in Condition 1, dogs chose between a slice of sausage and a dry pellet with no demonstration. In Condition 2, the same choice was available but with a person (owner/stranger) showing a preference for the dry pellet. In Condition 3, dogs chose between a single dry pellet and 8 slices of sausage, with the person (owner/stranger) showing a preference for the pellet. In both experiments, dogs conformed to the human's indications even though these led to the selection of the less advantageous option (i.e. the smaller amount of food in Experiment 1 or the low quality food in Experiment 2). However, the owner and the stranger did not differently influence the dogs' behaviour. Results show that dogs are willing to follow a person's indication even when this is visibly (if perhaps only mildly) counterproductive to them and that they are socially prepared to rely equally on cues given by the owner and an unfamiliar friendly person.

Routine use of preventative medicines is advocated as part of responsible dog and cat ownership. However, it has been suggested that the number of owners in the United Kingdom (UK) using preventative medicines to protect their pets is in decline. The aim of this novel study was to use a qualitative methodology to explore the attitudes of pet owners and veterinary surgeons in the UK to using preventative medicine products in dogs and cats. Preventative medicine was defined as "a drug or any other preparation used to prevent disease, illness or injury." Semi-structured interviews were conducted by telephone with owners and veterinary surgeons who had recently participated in a preventative healthcare consultation. Thematic analysis of transcribed recordings of these interviews identified four themes. This paper reports the theme related to motivators and barriers to using preventative medicines. Owners' understanding varied widely about the importance of preventative medicines for pets, as did their confidence in the safety of prescription products. A good relationship with their veterinary surgeon or practice, seeing adverts on the television about specific diseases, advice from a breeder and having personally seen infected animals appeared to be motivators for owners to use preventative medicines. Concern about adverse events and uncertainty about the necessity of using preventative medicines were barriers. Owners who trusted their veterinary surgeons to advise them on preventative medicine products described little use of alternative information sources when making preventative medicine choices. However, owners who preferred to do their own research described reading online opinions, particular in relation to the safety of preventative medicines, which they found confusing. In contrast, veterinary surgeons described broad confidence in the safety and efficacy of prescription preventative medicines and described protection of pet health as a strong motivator for

Small-to-medium enterprises (SMEs) require specialized attention regarding workplace mental health (WMH), but can be challenging to engage in WMH promotion interventions. This cross-sectional study analyzed self-reported motivations of SME owner/managers who engaged in a WMH promotion intervention specifically designed for SMEs. Data from 297 SME owner/managers was thematically coded prior to conducting multinominal logistical regression analyses to determine reasons for engagement based on a series of predictors, including owner/manager psychological distress, recent experience of a stressful work event, and business confidence. Owner/manager psychological distress, experience of a recent stressful workplace, and low 12-month business confidence incident were important predictors of engagement. The findings provide important insights into the uptake of a WMH promotion intervention, which can inform the design and future recruitment strategies for WMH promotion interventions within the SME sector.

This report summarizes the work conducted under U.S. Department of Energy (DOE) under contract DE-FC36-04GO14285 by Mercedes-Benz & Research Development, North America (MBRDNA), Chrysler, Daimler, Mercedes Benz USA (MBUSA), BP, DTE Energy and NextEnergy to validate fuel cell technologies for infrastructure, transportation as well as assess technology and commercial readiness for the market. The Mercedes Team, together with its partners, tested the technology by operating and fueling hydrogen fuel cell vehicles under real world conditions in varying climate, terrain and driving conditions. Vehicle and infrastructure data was collected to monitor the progress toward the hydrogen vehicle and infrastructure performance targets of $2.00 to 3.00/gge hydrogen production cost and 2,000-hour fuel cell durability. Finally, to prepare the public for a hydrogen economy, outreach activities were designed to promote awareness and acceptance of hydrogen technology. DTE, BP and NextEnergy established hydrogen filling stations using multiple technologies for on-site hydrogen generation, storage and dispensing. DTE established a hydrogen station in Southfield, Michigan while NextEnergy and BP worked together to construct one hydrogen station in Detroit. BP constructed another fueling station in Burbank, California and provided a full-time hydrogen trailer at San Francisco, California and a hydrogen station located at Los Angeles International Airport in Southern, California. Stations were operated between 2005 and 2011. The Team deployed 30 Gen I Fuel Cell Vehicles (FCVs) in the beginning of the project. While 28 Gen I F-CELLs used the A-Class platform, the remaining 2 were Sprinter delivery vans. Fuel cell vehicles were operated by external customers for real-world operations in various regions (ecosystems) to capture various driving patterns and climate conditions (hot, moderate and cold). External operators consisted of F-CELL partner organizations in California and Michigan

2018-05-15

Increased globalisation and climate change have led to concern about the increasing risk of arthropod-borne virus (arbovirus) outbreaks globally. An outbreak of equine arboviral disease in northern Europe could impact significantly on equine welfare, and result in economic losses. Early identification of arboviral disease by horse owners may help limit disease spread. In order to determine what horse owners understand about arboviral diseases of horses and their vectors, the authors undertook an open, cross-sectional online survey of UK horse owners. The questionnaire was distributed using social media and a press release and was active between May and July 2016. There were 466 respondents, of whom 327 completed the survey in full. High proportions of respondents correctly identified photographic images of biting midges (71.2 per cent) and mosquitoes (65.4 per cent), yet few were aware that they transmit equine infectious diseases (31.4 per cent and 35.9 per cent, respectively). Of the total number of respondents, only 7.4 per cent and 16.2 per cent correctly named a disease transmitted by biting midges and mosquitoes, respectively. Only 13.1 per cent and 12.5 per cent of participants identified specific clinical signs of African horse sickness (AHS) and West Nile virus (WNV), respectively. This study demonstrates that in the event of heightened disease risk educational campaigns directed towards horse owners need to be implemented, focussing on disease awareness, clinical signs and effective disease prevention strategies. © British Veterinary Association (unless otherwise stated in the text of the article) 2018.

Radtke, Thomas; Fritzsche, Stephan; Surzhykov, Andrey

2005-01-01

Density matrix theory is applied to re-investigate the entanglement in the spin state of pairs of electrons following the photoionization of trapped, hydrogen-like ions. For the ionization of one out of two non-interacting atoms, in particular, we analyzed how the entanglement between the electrons is changed owing to their interaction with the radiation field. Detailed calculations on the concurrence of the final spin-state of the electrons have been performed for the photoionization of hydrogen as well as for hydrogen-like Xe 53+ and U 91+ ions. From these computations it is shown that the degree of entanglement, which is quite well preserved for neutral hydrogen, will be strongly affected by relativistic and non-dipole effects of the radiation field as the nuclear charge of the ions is increased

Finkler, Hilit; Terkel, Joseph

2012-04-01

The attitudes and behaviours of cat owners in regard to treatment of cats may have a cumulative effect on the food availability, reproduction, density and welfare of the free-roaming cat population and thus also on the extent of cat overpopulation. Understanding this is thus a vital step in the a priori planning of cat management programs on any scale, as well as in developing public education programs on this issue. Although recent years have seen an accumulation of knowledge in regard to cat owners' attitudes and behaviours, the findings vary among countries and locations and in Israel this has never been investigated systematically. Using a questionnaire provided to cat owners in veterinary clinics, this study aimed at identifying those attitudes and behaviours that may be contributing to cat overpopulation in Tel Aviv, Israel, and at exploring the socio-economic factors that influence this problem. The findings show that the influential factors can be predicted from the cat owners' socio-economic status, mainly education and income, as well as gender and age. A consistency in those cat owner behaviours that contribute to cat overpopulation was also uncovered, revealing a sub-population of individuals who persist in the undesirable behaviours. Finally, a strong relationship between attitude and consequent behaviour was demonstrated, indicating the importance of education and targeted publicity as a means to influence attitudes and thereby change behaviours in this respect. We propose several measures by which to reduce the current extent of cat owners' contribution to the cat overpopulation: discouraging unwanted owner behaviours such as abandonment of their cats and allowing them to breed; promoting awareness of the neutering option among cat caretakers; and increasing pre-adoption neutering rates in shelters. Regional and national laws promoting responsible pet ownership need to be enacted. By improving the current level of knowledge and awareness among cat

Highlights: •Hydrostatic pressure increases the Volmer and the Heyrovsky reactions rates. •Hydrostatic pressure decreases the Tafel reaction rate. •Hydrogen adsorption conditions change with pressure under −1.2 and −1.3 V SSE . •Under −1.2 and −1.3 V SSE , the Heyrovsky reaction dominates the hydrogen recombination. •Under −1.0 and −1.1 V SSE , the Tafel reaction dominates the hydrogen recombination. -- Abstract: A new electrochemical impedance spectroscopy (EIS) model, which considers both the Tafel recombination and the Heyrovsky reaction under permeable boundary conditions, was developed to characterize the kinetic parameters of the hydrogen evolution reaction (HER) under hydrostatic pressure. The effect of the hydrostatic pressure on the kinetic parameters of the HER and the permeation of A514 steel in alkaline solution were measured using potentiodynamic polarization, the Devanathan cell hydrogen permeation, and EIS. The hydrostatic pressure accelerates the Volmer reaction and inhibits the Tafel recombination, which increases the number of adsorbed hydrogen atoms. On the other hand, the pressure accelerates the Heyrovsky reaction, which decreases the amount of adsorbed hydrogen atoms. At 10 to 40 MPa hydrostatic pressure within the −1.0 to −1.1 V SSE cathodic potential region, the HER is controlled by hydrogen partial pressure, and hydrogen adsorption is the Langmuir type. Within the −1.2 to −1.3 V SSE cathodic potential region, the HER is controlled by the potential, and hydrogen adsorption gradually transfers from the Langmuir type to the Temkin type with increasing hydrostatic pressure.

Fueling our future: four steps to a new reliable, cleaner, decentralized energy supply based on Hydrogen and fuel cells

International Nuclear Information System (INIS)

Evers, A.

2005-01-01

In examining various market strategies, this presentation demonstrates the possible driving factors and necessary elements needed to move Hydrogen and Fuel Cells (H2/FC) to worldwide commercialisation. Focusing not only on the technology itself, this presentation looks at the 'bigger picture' explaining how certain trends have impacted the progress of new technologies developments in the past. The presentation demonstrates how these models can be applied to our present day situation. In this process, the consumer has played and will continue to play the key and leading role. Due to such strong influence, the consumer will ultimately fuel the future of H2/FC commercialisation by a desire for new and not yet discovered products and services. Examining different Distributed Generation scenarios, the catalyst to the Hydrogen Economy may be found through distributed generation via fuel cells. One possible step could be the use of Personal Power Cars equipped with Fuel Cells which not only drive on Hydrogen, but also supply (while standing) electricity /heat to residential and commercial buildings. The incentive for car owners driving and using these vehicles is twofold: either save (at his own home) or earn (at his office) money while their cars are parked and plugged into buildings via smart docking stations available at key parking sites. Cars parked at home in the garage will supply electricity to the homes and additionally, replace the function of the existing boiler. Car owners can earn money by selling the electricity generated (but not needed at that time) to the utilities and feed it into the existing electricity grid. The inter-dependability between supply and consumer-driven demand (or better, demand and supply) and other examples are explained. The steps necessary to achieve a new, reliable, cleaner and decentralized Energy Supply based on H2/FC are also presented and examined. (author)

Is the owner entitled to radiographs taken of his animal?

International Nuclear Information System (INIS)

Hartung, K.

1990-01-01

In the Federal Republic of Germany a veterinarian owns radiographs taken of animals in his practice. They have to be filed like any other results of diagnostic procedures. This is important, because evidence is required in the case of a law suit. On the other hand, it has to be stressed that taking radiographs is the subject of a free contract between owner and veterinarian. So it is possible to take the radiographs solely with the purpose of giving them to the owner, who may have them analysed by any other veterinarian of his choice. This is especially true in hip radiographs, which are evaluated and filed by an adjudicator of the breed association. In any case the radiologist has the obligation to lend the radiographs to another veterinarian on request for inspection. The second veterinarian has to give them back as soon as possible

We investigated the percentage of dogs that could be vaccinated against rabies by conducting a pilot campaign in N'Djaména, Chad. Owners were charged US$4.13 per dog vaccinated, and 24% of all dogs in the three city districts covered by the campaign were vaccinated. Total campaign costs were US$7623, resulting in an average of US$19.40 per vaccinated dog. This is five times more expensive than the cost per animal vaccinated during a previous free vaccination campaign for dog-owners, conducted in the same districts. The free campaign, which vaccinated 2605 more dogs than this campaign, cost an additional US$1.45 per extra dog vaccinated. Campaigns in which owners are charged for vaccinations result in lower vaccination rates than in free campaigns. Public health officials can use these results when evaluating the costs and benefits of subsidizing dog rabies vaccination programmes.

Review of Design Data for Safety Assessment of Tokai Reprocessing Plant. Control of hydrogen gas produced by radiolysis of reprocessing solutions at Tokai Reprocessing Plant

Radioactive materials in aqueous solution at a nuclear fuel reprocessing plant causes radiolytic generation of several gases including hydrogen. Hydrogen accumulating in equipment can be an explosion hazard. In such plants, though the consideration in the design has been fundamentally made in order to remove the ignition source from the equipment, the hydrogen concentration in the equipment should not exceed the explosion threshold. It is, therefore, desired to keep the hydrogen concentration lower than the explosion threshold by dilution with the air introduced into equipment, from the viewpoint which previously prevents the explosion. This report describes the calculation of hydrogen generation, evaluation of hydrogen concentration under abnormal operation and consideration of possible improvement at Tokai Reprocessing Plant. The amount of hydrogen generation was calculated for each equipment from available data on radiolysis induced by radioactive materials. Taking into consideration for abnormal condition that is single failure of air supply and loss of power supply, the investigation was made on the method for controlling so that the hydrogen concentration may not exceed the explosion threshold. Possible means which can control the concentration of hydrogen gas under the explosion threshold have been also investigated. As the result, it was found that hydrogen concentration of most equipment was kept under the explosion threshold. It was also shown that improvement of the facility was necessary on the equipment in which the concentration of the hydrogen may exceed the explosion threshold. Proposals based on the above results are also given in this report. The above content has been described in 'Examination of the hydrogen produced by the radiolysis' which is a part of 'Reviews of Design Data for Safety Assessment of Tokai Reprocessing Plant' (JNC TN8410 99-002) published in February 1999.

Gasper, J.K.

1988-01-01

The Combustion Engineering (C-E) owner group was formed in 1979 to address the technical and regulatory issues for plants with nuclear steam supply systems supplied by C-E that resulted from the accident at the Three Mile Island plant. The group addressed many of the immediate concerns from the accident including the response of C-E owner-group plants to small-break loss-of-coolant accidents, the use of power-operated relief valves, emergency operating procedure upgrades, as well as transient and accident responses. The group was successful in addressing these technical and regulatory issues with the US Nuclear Regulatory Commission in such a manner that C-E owner-group plants were not required to shut down or operate at reduced power levels. In recent years, the group has increasingly pursued programs for the benefit of its members rather than because of a regulatory commitment. The major current activities of the group are programs to support the design basis reconstruction of our member plants, improvements to emergency procedure guidelines, which are the basis for the emergency operating procedures used in our plants, a charging pump performance improvement program, various activities to reduce the number of unplanned reactor scrams at our plants, modeling of steam generator corrosion mechanisms to improve steam generator performance, and leak-before-break justification of reactor coolant system piping

Despite its prevalence in emerging economies, everyday-life business deviance (EBD) and its antecedents have received surprisingly little research attention. Drawing on strain theory and the business-ethics literature, we develop a socio-psychological explanation for this deviance. Our analysis of 741 owners of Chinese small- and medium-sized enterprises (SMEs) suggests that materialism and trust in institutional justice affect EBD both directly and indirectly in a relationship mediated by th...

Hydrogen pumping speeds on panels of molecular sieve types 5A and Na-Y were compared for a variety of sieve (and chevron) temperatures between 10 and 30 K. Although pumping speeds declined with time, probably because of the slow diffusion of hydrogen from the surface of the sieve crystals into the internal regions, the different sieve materials and operating conditions could be compared using time-averaged pump speeds. The (average) pumping speeds declined with increasing temperature. Under some conditions, the Na-Y sieve performed much better than the 5A sieve. Studies of the effect of small concentrations (approx. 4%) of hydrogen on helium pumping indicate that compound cryopumps in fusion reactors will not have to provide complete screening of hydrogen from helium panels. The concentrations of hydrogen did not lower effective helium pumping speeds or shorten the helium operating period between instabilities. Studies of tritium recovery from blankets of liquid lithium focused on design and construction of a flowing-lithium test system and on ultimate removal of tritium from yttrium sorbents. At 505 0 C, tritium release from yttrium behaves as a diffusion-controlled process, but the release rates are very low. Apparently, higher temperatures will be required for effective sorbent regeneration. An innovative technique for separating hydrogen isotopes by using bipolar electrolysis with permeable electrodes was analyzed to determine its potential usefulness in multistage separation

The aims of this descriptive cross-sectional study were to investigate dog and cat acquisition and attitudes toward pet care among residents of the Chicago area (zip codes 60600-60660); to compare data obtained from owners of shelter-acquired pets with those of residents who acquired their pets from other sources; to compare data from dog owners with cat owners; and to compare pet health practices among the respondents of different zip code income groups. In-person surveys administered at five pet store locations collected data from 529 respondents, representing 582 dogs and 402 cats owned or continuously cared for in the past 3 years. Median household income data for represented zip codes was also obtained. Shelters were the most common source of cats (ppet stores, breeders or rescue organizations and to be kept as outdoor-only pets (pPet owners were most commonly 'very likely' (5 on a 1-5/5 Likert scale) to administer all hypothetical treatments discussed, although cat owners were less likely to spend time training their pet (p=0.05). Cat owners were less likely to have taken their pet to a veterinarian for vaccinations or annual physical exams (ppets were at least as willing as other respondents to administer hypothetical treatments and pay ≥$1000 for veterinary treatment. Respondents from site #3 lived in zip codes that had relatively lower median household incomes (ppets than those at the four other sites (ppet owners from all acquisition categories expressed very high levels of attachment (≥8-10/10 on a Likert scale), except for owners of cats acquired as strays (84.9%) or from the 'other' category (75.0%). Survey respondents commonly acquired their pets from shelters and those who did were at least as willing to pay for and provide veterinary care as respondents who owned pets acquired from other sources. The data collected provides a snapshot of the attitudes of survey respondents in the Chicago area toward pet acquisition and care. Copyright © 2014

Some hydrogen-control considerations for ice-condenser nuclear plants

1981-02-01

The proposal of the Tennessee Valley Authority (TVA) for coping with the problem of accident generated hydrogen gas in its Sequoyah ice-condenser plant was to put in place glow-plug igniters so that any hydrogen that is evolved during an accident could be burnt before accumulating into a dangerously large mass. Since it was desired to install these igniters in the Sequoyah and other plants as quickly as possible, the NRC asked the Lawrence Livermore National Laboratory (LLNL) to carry out some experiments on these igniters to delineate the region of their applicability

Prospects for hydrogen storage in graphene.

2013-01-07

Hydrogen-based fuel cells are promising solutions for the efficient and clean delivery of electricity. Since hydrogen is an energy carrier, a key step for the development of a reliable hydrogen-based technology requires solving the issue of storage and transport of hydrogen. Several proposals based on the design of advanced materials such as metal hydrides and carbon structures have been made to overcome the limitations of the conventional solution of compressing or liquefying hydrogen in tanks. Nevertheless none of these systems are currently offering the required performances in terms of hydrogen storage capacity and control of adsorption/desorption processes. Therefore the problem of hydrogen storage remains so far unsolved and it continues to represent a significant bottleneck to the advancement and proliferation of fuel cell and hydrogen technologies. Recently, however, several studies on graphene, the one-atom-thick membrane of carbon atoms packed in a honeycomb lattice, have highlighted the potentialities of this material for hydrogen storage and raise new hopes for the development of an efficient solid-state hydrogen storage device. Here we review on-going efforts and studies on functionalized and nanostructured graphene for hydrogen storage and suggest possible developments for efficient storage/release of hydrogen under ambient conditions.

The elucidation of cell metabolic mechanisms is the modern underpinning of the diagnosis, treatment, and in some cases the prevention of disease. Para-Hydrogen induced polarization (PHIP) enhances magnetic resonance imaging (MRI) signals over 10,000 fold, allowing for the MRI of cell metabolic mechanisms. This signal enhancement is the result of hyperpolarizing endogenous substances used as contrast agents during imaging. PHIP instrumentation hyperpolarizes Carbon-13 ((13)C) based substances using a process requiring control of a number of factors: chemical reaction timing, gas flow, monitoring of a static magnetic field (Bo), radio frequency (RF) irradiation timing, reaction temperature, and gas pressures. Current PHIP instruments manually control the hyperpolarization process resulting in the lack of the precise control of factors listed above, resulting in non-reproducible results. We discuss the design and implementation of a LabVIEW based computer program that automatically and precisely controls the delivery and manipulation of gases and samples, monitoring gas pressures, environmental temperature, and RF sample irradiation. We show that the automated control over the hyperpolarization process results in the hyperpolarization of hydroxyethylpropionate. The implementation of this software provides the fast prototyping of PHIP instrumentation for the evaluation of a myriad of (13)C based endogenous contrast agents used in molecular imaging.

Hydrogen Doping into MoO3 Supports toward Modulated Metal-Support Interactions and Efficient Furfural Hydrogenation on Iridium Nanocatalysts.

As promising supports, reducible metal oxides afford strong metal-support interactions to achieve efficient catalysis, which relies on their band states and surface stoichiometry. In this study, in situ and controlled hydrogen doping (H doping) by means of H 2 spillover was employed to engineer the metal-support interactions in hydrogenated MoO x -supported Ir (Ir/H-MoO x ) catalysts and thus promote furfural hydrogenation to furfuryl alcohol. By easily varying the reduction temperature, the resulting H doping in a controlled manner tailors low-valence Mo species (Mo 5+ and Mo 4+ ) on H-MoO x supports, thereby promoting charge redistribution on Ir and H-MoO x interfaces. This further leads to clear differences in H 2 chemisorption on Ir, which illustrates its potential for catalytic hydrogenation. As expected, the optimal Ir/H-MoO x with controlled H doping afforded high activity (turnover frequency: 4.62 min -1 ) and selectivity (>99 %) in furfural hydrogenation under mild conditions (T=30 °C, PH2 =2 MPa), which means it performs among the best of current catalysts. © 2018 Wiley-VCH Verlag GmbH & Co.

2014-09-05

A new materials analysis particle probe (MAPP) was designed, constructed and tested to develop understanding of particle control and hydrogenic fuel retention in lithium-based plasma-facing surfaces in NSTX. The novel feature of MAPP is an in-situ tool to probe the divertor NSTX floor during LLD and lithium-coating shots with subsequent transport to a post-exposure in-vacuo surface analysis chamber to measure D retention. In addition, the implications of a lithiated graphite-dominated plasma-surface environment in NSTX on LLD performance, operation and ultimately hydrogenic pumping and particle control capability are investigated in this proposal. MAPP will be an invaluable tool for erosion/redeposition simulation code validation.

The article aims to review the different approaches to intrafirm planning of owner's equity in industrial enterprises. Since charter capital, additional capital and reserve capital do not change in the process of enterprise activity, the main interest lies on the field of share repurchases from shareholders and retained earnings within the owner's equity of the enterprise. In order to study the effect of share repurchases on the activities of the enterprise, let us use such mathematical methods as event study and econometric modeling. This article describes the step-by-step algorithm of carrying out event study and justifies the choice of Logit model in econometric analysis. The article represents basic results of conducted regression analysis on the effect of share repurchases on the key financial indicators in industrial enterprises.

Hydrogen behavior in light-water reactors

International Nuclear Information System (INIS)

Berman, M.; Cummings, J.C.

1984-01-01

The Three Mile Island accident resulted in the generation of an estimated 150 to 600 kg of hydrogen, some of which burned inside the containment building, causing a transient pressure rise of roughly 200 kPa (2 atm). With this accident as the immediate impetus and the improved safety of reactors as the long-term goal, the nuclear industry and the Nuclear Regulatory Commission initiated research programs to study hydrogen behavior and control during accidents at nuclear plants. Several fundamental questions and issues arise when the hydrogen problem for light-water-reactor plants is examined. These relate to four aspects of the problem: hydrogen production; hydrogen transport, release, and mixing; hydrogen combustion; and prevention or mitigation of hydrogen combustion. Although much has been accomplished, some unknowns and uncertainties still remain, for example, the rate of hydrogen production during a degraded-core or molten-core accident, the rate of hydrogen mixing, the effect of geometrical structures and scale on combustion, flame speeds, combustion completeness, and mitigation-scheme effectiveness. This article discusses the nature and extent of the hydrogen problem, the progress that has been made, and the important unresolved questions

Hydrogen risk reduction in Nuclear power plant

In case of a severe accident in a nuclear power plant with core melt and hydrogen production, the hydrogen risk is one of the main concerns. It may jeopardize the containment integrity due to violent deflagration that can lead to DDT (Deflagration Detonation Transient) or even detonation of proper hydrogen mitigation means are not available. The design of the EPR (European Pressurized water Reactor) Hydrogen mitigation and control system is based on the lumped parameter code WAVCO and the 3D code GASFLOW. The concept consists of recombiners and igniters to cope with all scenarios including those without steam. The system has been checked to avoid DDT by the 7λ criteria that's implemented in GASFLOW. Future analysis could deal with determining dynamic pressure loads, if appropriate, and some sensitivity studies to check the hydrogen control measures with respect to different source locations and mass flow rates. Also a conditional criterion for determining the likelihood of fast deflagration should be developed. (author)

2017-03-01

In this paper, a performance comparison among three well-known stochastic model predictive control approaches, namely, multi-scenario, tree-based, and chance-constrained model predictive control is presented. To this end, three predictive controllers have been designed and implemented in a real renewable-hydrogen-based microgrid. The experimental set-up includes a PEM electrolyzer, lead-acid batteries, and a PEM fuel cell as main equipment. The real experimental results show significant differences from the plant components, mainly in terms of use of energy, for each implemented technique. Effectiveness, performance, advantages, and disadvantages of these techniques are extensively discussed and analyzed to give some valid criteria when selecting an appropriate stochastic predictive controller.

Hydrogen considerations in light-water power reactons

International Nuclear Information System (INIS)

Keilholtz, G.W.

1976-02-01

A critical review of the literature now available on hydrogen considerations in light-water power reactors (LWRs) and a bibliography of that literature are presented. The subject matter includes mechanisms for the generation of hydrogen-oxygen mixtures, a description of the fundamental properties of such mixtures, and their spontaneous ignition in both static and dynamic systems. The limits for hydrogen flammability and flame propagation are examined in terms of the effects of pressure, temperature, and additives; the emphasis is on the effects of steam and water vapor. The containment systems for pressurized-water reactors (PWRs) and boiling-water reactors (BWRs) are compared, and methods to control hydrogen and oxygen under the conditions of both normal operation and postulated accidents are reviewed. It is concluded that hydrogen can be controlled so that serious complications from the production of hydrogen will not occur. The bibliography contains abstracts from the computerized files of the Nuclear Safety Information Center. Key-word, author, and permuted-title indexes are provided. The bibliography includes responses to questions asked by the U. S. Nuclear Regulatory Commission (NRC) which relate to hydrogen, as well as information on normal operations and postulated accidents including generation of hydrogen from core sprays. Other topics included in the ten sections of the bibliography are metal-water reactions, containment atmosphere, radiolytic gas, and recombiners

Electron Charged Graphite-based Hydrogen Storage Material

The electron-charge effects have been demonstrated to enhance hydrogen storage capacity using materials which have inherent hydrogen storage capacities. A charge control agent (CCA) or a charge transfer agent (CTA) was applied to the hydrogen storage material to reduce internal discharge between particles in a Sievert volumetric test device. GTI has tested the device under (1) electrostatic charge mode; (2) ultra-capacitor mode; and (3) metal-hydride mode. GTI has also analyzed the charge distribution on storage materials. The charge control agent and charge transfer agent are needed to prevent internal charge leaks so that the hydrogen atoms can stay on the storage material. GTI has analyzed the hydrogen fueling tank structure, which contains an air or liquid heat exchange framework. The cooling structure is needed for hydrogen fueling/releasing. We found that the cooling structure could be used as electron-charged electrodes, which will exhibit a very uniform charge distribution (because the cooling system needs to remove heat uniformly). Therefore, the electron-charge concept does not have any burden of cost and weight for the hydrogen storage tank system. The energy consumption for the electron-charge enhancement method is quite low or omitted for electrostatic mode and ultra-capacitor mode in comparison of other hydrogen storage methods; however, it could be high for the battery mode.

Evaluating the Alignment of Organizational and Project Contexts for BIM Adoption: A Case Study of a Large Owner Organization

2015-11-01

Full Text Available Building information modeling (BIM has been presented as a potential solution to current facilities management problems related to information exchange during handover, and facilities information management during operations. However, implementing BIM in an owner organization is a complex challenge that necessitates reconfiguration of work practices and internal structures to fully realize the benefits. Owners are often unsure about how or whether they should go through the challenges related to implementation. Although previous studies have documented the potential benefits of BIM adoption for owners, such as improvements in work order processing, very little research has specifically looked at the transition to BIM and the scale of the effort required for large and diverse owner organizations. This paper presents the results of a long-term embedded case study analysis of a large owner-operator institutional organization that investigated the alignment of facility management (FM practices across organizational and project contexts. The research objective was to examine current organizational practices in order to understand the potential, as well as the challenges, of transitioning from a paper-based to a model-based approach in handover and operations. We describe the current state of handover, information management and facility management practices and developed a framework to characterize the alignment between organizational constructs, available technology, project artifacts and owner requirements. This investigation of the current state of practice enables us to understand the gap between available and required information, processes and technology, and to better understand the enormous challenges owners face when considering the transition to BIM.

The determinants of the readiness to let go among senior generation owner-managers of small and medium-sized family businesses

Directory of Open Access Journals (Sweden)

Stephan P van der Merwe

2010-09-01

Full Text Available The objective of this study was to assess the determinants of the readiness of the senior generation owner-managers to finally transfer the management and control of the family business to the younger generation. Data from 504 questionnaires linked to 81 family businesses were collected and analysed. An Oblimin oblique rotation was carried out on the principal components of the exploratory factor analysis. Five factors with eigen-values greater than one, explaining 62.64 per cent of the variance, were extracted. These five factors describing the theoretical dimensions of the dependent variable were: the senior generation owner-manager’s readiness to let go, and the independent variables of retirement planning, perceived suitability of the successor, estate planning, and the perceived liquidity of the business after the transfer. No significant practical differences relating to these five factors could be found between the perceptions of male and female respondents, the senior and younger generation family members or family members involved in medium-sized or small businesses. Practical recommendations are suggested to ensure a smooth final transfer of the management and control of the business to the younger generation family members.

Hydrogen gas driven permeation through tungsten deposition layer formed by hydrogen plasma sputtering

Highlights: • H permeation tests for W layer formed by H plasma sputtering are performed. • H permeation flux through W layer is larger than that through W bulk. • H diffusivity in W layer is smaller than that in W bulk. • The equilibrium H concentration in W layer is larger than that in W bulk. - Abstract: It is important to evaluate the influence of deposition layers formed on plasma facing wall on tritium permeation and tritium retention in the vessel of a fusion reactor from a viewpoint of safety. In this work, tungsten deposition layers having different thickness and porosity were formed on circular nickel plates by hydrogen RF plasma sputtering. Hydrogen permeation experiment was carried out at the temperature range from 250 °C to 500 °C and at hydrogen pressure range from 1013 Pa to 101,300 Pa. The hydrogen permeation flux through the nickel plate with tungsten deposition layer was significantly smaller than that through a bare nickel plate. This indicates that a rate-controlling step in hydrogen permeation was not permeation through the nickel plate but permeation though the deposition layer. The pressure dependence on the permeation flux differed by temperature. Hydrogen permeation flux through tungsten deposition layer is larger than that through tungsten bulk. From analysis of the permeation curves, it was indicated that hydrogen diffusivity in tungsten deposition layer is smaller than that in tungsten bulk and the equilibrium hydrogen concentration in tungsten deposition layer is enormously larger than that in tungsten bulk at same hydrogen pressure.

Tailoring NIST Security Controls for the Ground System: Selection and Implementation -- Recommendations for Information System Owners

Science.gov (United States)

Takamura, Eduardo; Mangum, Kevin

2016-01-01

. Certain protective measures for the general enterprise may not be as efficient within the ground segment. This is what the authors have concluded through observations and analysis of patterns identified from the various security assessments performed on NASA missions such as MAVEN, OSIRIS-REx, New Horizons and TESS, to name a few. The security audits confirmed that the framework for managing information system security developed by the National Institute of Standards and Technology (NIST) for the federal government, and adopted by NASA, is indeed effective. However, the selection of the technical, operational and management security controls offered by the NIST model - and how they are implemented - does not always fit the nature and the environment where the ground system operates in even though there is no apparent impact on mission success. The authors observed that unfit controls, that is, controls that are not necessarily applicable or sufficiently effective in protecting the mission systems, are often selected to facilitate compliance with security requirements and organizational expectations even if the selected controls offer minimum or non-existent protection. This paper identifies some of the standard security controls that can in fact protect the ground system, and which of them offer little or no benefit at all. It offers multiple scenarios from real security audits in which the controls are not effective without, of course, disclosing any sensitive information about the missions assessed. In addition to selection and implementation of controls, the paper also discusses potential impact of recent legislation such as the Federal Information Security Modernization Act (FISMA) of 2014 - aimed at the enterprise - on the ground system, and offers other recommendations to Information System Owners (ISOs).

Hot Hydrogen Test Facility

2007-01-01

The core in a nuclear thermal rocket will operate at high temperatures and in hydrogen. One of the important parameters in evaluating the performance of a nuclear thermal rocket is specific impulse, ISp. This quantity is proportional to the square root of the propellant's absolute temperature and inversely proportional to square root of its molecular weight. Therefore, high temperature hydrogen is a favored propellant of nuclear thermal rocket designers. Previous work has shown that one of the life-limiting phenomena for thermal rocket nuclear cores is mass loss of fuel to flowing hydrogen at high temperatures. The hot hydrogen test facility located at the Idaho National Lab (INL) is designed to test suitability of different core materials in 2500 C hydrogen flowing at 1500 liters per minute. The facility is intended to test non-uranium containing materials and therefore is particularly suited for testing potential cladding and coating materials. In this first installment the facility is described. Automated Data acquisition, flow and temperature control, vessel compatibility with various core geometries and overall capabilities are discussed

Renewable solar hydrogen production and utilization

2006-01-01

There is a tremendous opportunity to generate large quantities of hydrogen from low grade and economical sources of methane including landfill gas, biogas, flare gas, and coal bed methane. The environmental benefits of generating hydrogen using renewable energy include significant greenhouse gas and air contaminant reductions. Solar Hydrogen Energy Corporation (SHEC LABS) recently constructed and demonstrated a Dry Fuel Reforming (DFR) hydrogen generation system that is powered primarily by sunlight focusing-mirrors in Tempe, Arizona. The system comprises a solar mirror array, a temperature controlling shutter system, and two thermo-catalytic reactors to convert methane, carbon dioxide, and water into hydrogen. This process has shown that solar hydrogen generation is feasible and cost-competitive with traditional hydrogen production. The presentation will provide the following: An overview of the results of the testing conducted in Tempe, Arizona; A look at the design and installation of the scaled-up technology site at a landfill site in Canada; An examination of the economic and environmental benefits of renewable hydrogen production using solar energy

Wilson, Colleen; Bain, Melissa; DePorter, Theresa; Beck, Alexandra; Grassi, Vanessa; Landsberg, Gary

2016-10-01

This study was performed to examine aspects of the cat, environment and scratching post that might influence scratching behavior, in an effort to determine how inappropriate scratching behavior might be refocused on acceptable targets. An internet survey, posted on several public websites, gathered details about scratching behavior, as described by owners in their home environments, from 4331 respondents over a 4 month period. Responses from 39 different countries were analyzed, mostly from the USA, Canada and the UK. Owners offered traditionally recommended scratching substrates including rope, cardboard, carpet and wood. Rope was most frequently used when offered, although carpet was offered most commonly. Most owners provided at least one scratching post; cats scratched the preferred substrate more often when the post was a simple upright type or a cat tree with two or more levels and at least 3 ft high. Narrower posts (base width ⩽3 ft) were used more often than wider posts (base width ⩾5 ft). Intact or neutered cats (males and females) were as likely to scratch inappropriately, and inappropriate scratching decreased with age. Geriatric cats between the ages of 10 and 14 years preferred carpet substrate most frequently; all other ages preferred rope first. Inappropriate scratching decreased as the different types/styles of posts increased in the home. Inappropriate scratching did not increase if the number of cats or dogs increased in the household. Declawed cats were preventatively declawed most often to prevent household item destruction.

The well-known radical and ion scavenger techniques of application in amorphous hydrogenated carbon film deposition studies are investigated in relation to the mechanism of tritium and deuterium co-deposition in carbon-dominated fusion devices. A particularly successful scheme results from the injection of nitrogen into methane/hydrogen plasmas for conditions close to those prevailing in the divertor region of present fusion devices. A complete suppression of the a-C : H film deposition has been achieved for N 2 /CH 4 ratios close to one in methane (5%)/hydrogen DC plasma. The implications of these findings in the tritium retention control in future fusion reactors are addressed. (author). Letter-to-the-editor

The multiphase catalytic decomposition of hydrogen peroxide into water and oxygen is notoriously susceptible to thermal runaway (heat of reaction: -98 kJ mol{sup -1}). The high surface area to volume ratio (S/V) in a microscale packed bed (MPB) reactor (radius 0.5 mm) was investigated for reducing the risk of thermal runaway during hydrogen peroxide decomposition to oxygen intended as a fuel cell oxidant aboard an unmanned undersea vehicle (UUV). A microscale reactor channel with a S/V of {proportional_to}2 x 10{sup 3} m{sup 2} m{sup -3} simulated under convective cooling generated a significant heat rise (T rise {proportional_to} 100 K), whereas a microreactor with a higher S/V ({proportional_to}200 x 10{sup 3} m{sup 2} m{sup -3}) achieved thermal control (T rise < 10 K) over the simulated reaction zone. Although thermal management was successfully accomplished using the higher S/V, experimental conversions of hydrogen peroxide to oxygen (5-18%) measured from the outlet were lower than simulated conversions (38-63%). Simulation assumptions, such as homogeneously dispersed flow and perfect catalyst interaction among other factors, contributed to the discrepancies between the simulated and experimental degrees of peroxide conversion to oxygen. Even though thermal control of the MPB was achieved, this work indicates that mass transfer limitations are a factor in the MPB reactor during a multiphase reaction, like decomposition of hydrogen peroxide to oxygen and water, and suggests means to overcome them even on the microscale level.

Equine injury and disease cause two types of costs for those financially responsible for treating and caring for the infected horse(s); direct costs of treating the horse and indirect cost of lost use of the horse for a period of time to the user of the horse (daily horse use). Indirect costs are more difficult to estimate but pose significant financial implications for equine-owners/caregivers. Additionally, there exists a gap in existing research regarding the valuation of infectious treatment options in horses. To estimate the value a US horse-owner/caregiver places on daily horse use and describe respondents' willingness-to-pay for various attributes of equine treatment options. Online questionnaire survey. An online questionnaire was provided to equine-owners and caretakers, and owner demographic, horse care and horse use information from respondents were requested. Additionally, respondents were presented with hypothetical disease treatment options with the following attributes: daily dosage, number of days of rest required, route of administration and out-of-pocket cost to the owner/caretaker through a choice experiment. Data were analysed using a rank-ordered logit analysis and willingness-to-pay estimates for daily use and treatment options were calculated. Results suggest that the average horse-owner with an uninsured and insured horse is willing to pay $12.07 (95% confidence interval: -$15.01, -$9.69) and $17.95 (95% confidence interval: -$25.30, -$11.20) per day to reduce lost use days required (due to need for rest) respectively. Respondents showed preferences for oral administration over treatments requiring i.m. injections. As this study employed an online survey it was subjected to self-selection bias and a sample size calculation was not performed. Veterinarians and pharmaceutical companies may use these results when promoting various treatment options to horse-owners/caregivers and in product development. Additionally, promotion efforts may be

System design description for SY-101 hydrogen mitigation test project data acquisition and control system (DACS-1)

International Nuclear Information System (INIS)

Truitt, R.W.; Pounds, T.S.; Smith, S.O.

1994-01-01

This document describes the hardware subsystems of the data acquisition and control system (DACS) used in mitigation tests conducted on waste tank SY-101 at the Hanford Nuclear Reservation. The system was designed and implemented by Los Alamos National Laboratory (LANL) and supplied to Westinghouse Hanford Company (WHC). The mitigation testing uses a pump immersed in the waste tank, directed at certain angles and operated at different speeds and time durations. The SY-101 tank has experienced recurrent periodic gas releases of hydrogen, nitrous oxide, ammonia, and (recently discovered) methane. The hydrogen gas represents a danger, as some of the releases are in amounts above the lower flammability limit (LFL). These large gas releases must be mitigated. Several instruments have been added to the tank to monitor the gas compositions, the tank level, the tank temperature, and other parameters. A mixer pump has been developed to stir the tank waste to cause the gases to be released at a slow rate. It is the function of the DACS to monitor those instruments and to control the mixer pump in a safe manner. During FY93 and FY94 the mixer pump was installed with associated testing operations support equipment and a mitigation test project plan was implemented. These activities successfully demonstrated the mixer pump's ability to mitigate the SY-101 tank hydrogen gas hazard

This thesis gives a systematic review of the fundamentals of energy systems, the governing physical and chemical laws related to energy, inherent characteristics of energy system, and the availability of the earth`s energy. It shows clearly why solar-hydrogen systems are one of the most viable options for the future. The main subject discussed is the modelling of SAPS (Stand-Alone Power Systems), with focus on photovoltaic-hydrogen energy systems. Simulation models for a transient simulation program are developed for PV-H{sub 2} components, including models for photovoltaics, water electrolysis, hydrogen storage, fuel cells, and secondary batteries. A PV-H{sub 2} demonstration plant in Juelich, Germany, is studied as a reference plant and the models validated against data from this plant. Most of the models developed were found to be sufficiently accurate to perform short-term system simulations, while all were more than accurate enough to perform long-term simulations. Finally, the verified simulation models are used to find the optimal operation and control strategies of an existing PV-H{sub 2} system. The main conclusion is that the simulation methods can be successfully used to find optimal operation and control strategies for a system with fixed design, and similar methods could be used to find alternative system designs. 148 refs., 78 figs., 31 tabs.

Storing Renewable Energy in the Hydrogen Cycle.

An energy economy based on renewable energy requires massive energy storage, approx. half of the annual energy consumption. Therefore, the production of a synthetic energy carrier, e.g. hydrogen, is necessary. The hydrogen cycle, i.e. production of hydrogen from water by renewable energy, storage and use of hydrogen in fuel cells, combustion engines or turbines is a closed cycle. Electrolysis splits water into hydrogen and oxygen and represents a mature technology in the power range up to 100 kW. However, the major technological challenge is to build electrolyzers in the power range of several MW producing high purity hydrogen with a high efficiency. After the production of hydrogen, large scale and safe hydrogen storage is required. Hydrogen is stored either as a molecule or as an atom in the case of hydrides. The maximum volumetric hydrogen density of a molecular hydrogen storage is limited to the density of liquid hydrogen. In a complex hydride the hydrogen density is limited to 20 mass% and 150 kg/m(3) which corresponds to twice the density of liquid hydrogen. Current research focuses on the investigation of new storage materials based on combinations of complex hydrides with amides and the understanding of the hydrogen sorption mechanism in order to better control the reaction for the hydrogen storage applications.

How life insurance can benefit the business owner

There are many situations when life insurance can fill the financial needs of business owners. Three of the most common needs are business continuation/value conservation (buy-sell agreement), asset conservation upon death or disability of a key employee (replace the value of a key employee upon death or disability), and the reward and retention of selected employees (bonus or deferred compensation). Let's take a closer look to see why life insurance makes sense in these three areas

To determine the prevalence of cross-species sharing of Escherichia coli between healthy dogs and humans living in the same household. Two faecal E. coli isolates from 25 healthy dog-owner pairs and 16 healthy control humans were tested using three fingerprinting methods. The prevalence of within-household sharing of E. coli was 4, 8 and 8% using pulsed-field gel electrophoresis, randomly amplified polymorphic DNA and enterobacterial repetitive intergenic consensus-PCR analyses respectively. Within-household bacterial sharing was more prevalent than across-household sharing (P fingerprinting techniques will help to find ways for reducing the economic impact of E. coli infections. This study support claims that public health concerns regarding the cross-species sharing of E. coli are warranted but this risk is minimal. © 2015 The Society for Applied Microbiology.

Hydrogen in hydrogenated amorphous silicon thick film and its relation to the photoresponse of the film in contact with molybdenum

International Nuclear Information System (INIS)

Sridhar, N.; Chung, D.D.L.

1992-01-01

This paper reports that hydrogenated amorphous silicon films of thickness 0.5-7 μm on molybdenum substrates were deposited from silane by dc glow discharge and studied by mass spectrometric observation of the evolution of hydrogen upon heating and correlating this information with the photoresponse. The films were found to contain two types of hydrogen, namely weak bonded hydrogen, which evolved at 365 degrees C and was the minority, and strongly bonded hydrogen, which evolved at 460-670 degrees C and was the majority. The proportion of strongly bonded hydrogen increased with increasing film thickness and with increasing substrate temperature during deposition. The total amount of hydrogen increased when the substrate temperature was decreased from 350 to 275 degrees C. The strongly bonded hydrogen resided throughout the thickness of the film, whereas the weakly bonded hydrogen resided near the film surface. The evolution of the strongly bonded hydrogen was diffusion controlled, with an activation energy of 1.6 eV. The strongly bonded hydrogen enhanced the photoresponse, whereas the weakly bonded hydrogen degraded the photoresponse

Electrolytic hydrogen offers a promising alternative for long-term energy storage of renewable energies (RE). A stand-alone RE system based on hydrogen production has been developed at the Hydrogen Research Institute and successfully tested for automatic operation with designed control devices. The system is composed of a wind turbine, a photovoltaic (PV) array, an electrolyser, batteries for buffer energy storage, hydrogen and oxygen storage tanks, a fuel cell, AC and DC loads, power conditioning devices and different sensors. The long-term excess energy with respect to load demand has been sent to the electrolyser for hydrogen production and then the fuel cell has utilised this stored hydrogen to produce electricity when there were insufficient wind and solar energies with respect to load requirements. The RE system components have substantially different voltage-current characteristics and they are integrated on the DC bus through power conditioning devices for optimal operation by using the developed Maximum Power Point Tracking (MPPT) control method. The experimental results show that the power gain obtained by this method clearly increases the hydrogen production and storage rate from wind-PV systems. (authors)

Hydrogen economy and nuclear energy

International Nuclear Information System (INIS)

Knapp, V.

Global energy outlooks based on present trends, such as WETO study, give little optimism about fulfilling Kyoto commitments in controlling CO2 emissions and avoiding unwanted climate consequences. Whilst the problem of radioactive waste has a prominence in public, in spite of already adequate technical solutions of safe storage for future hundreds and thousands of years, there s generally much less concern with influence of fossil fuels on global climate. In addition to electricity production, process heat and transportation are approximately equal contributors to CO2 emission. Fossil fuels in transportation present also a local pollution problem in congested regions. Backed by extensive R and D, hydrogen economy is seen as the solution, however, often without much thought where from the hydrogen in required very large quantities may come. With welcome contributions from alternative sources, nuclear energy is the only source of energy capable of producing hydrogen in very large amounts, without parallel production of CO2. Future high temperature reactors could do this most efficiently. In view of the fact that nuclear weapon proliferation is not under control, extrapolation from the present level of nuclear power to the future level required by serious attempts to reduce global CO2 emission is a matter of justified concern. Finding the sites for many hundreds of new reactors would, alone, be a formidable problem in developed regions with high population density. What is generally less well understood and not validated is that the production of nuclear hydrogen allows the required large increases of nuclear power without the accompanied increase of proliferation risks. Unlike electricity, hydrogen can be economically shipped or transported by pipelines to places very far from the place of production. Thus, nuclear production of hydrogen can be located and concentrated at few remote, controllable sites, far from the population centers and consumption regions. At such

This study evaluated dog and cat allergies and their association with allergen avoidance measures in Korean adults. The study population consisted of 537 adults who currently kept dogs or cats and participated in a pet exhibition in Korea. The subjects were asked to complete questionnaires regarding pet ownership, allergen avoidance, and allergy symptoms, and underwent skin prick tests. They were considered to have a dog or cat allergy if they suffered from one or more of allergy symptoms during contact with their pets. In total, 103 of 407 dog owners (25.3%) and 45 of 130 cat owners (34.6%) had a dog or cat allergy, respectively. Dog owners kept 1.3±1.5 dogs; this number did not differ according to the presence of dog allergy. Dog owners with a dog allergy had owned their dogs longer than those without (88.0±72.0 vs 67.5±72.7 months, PCat owners kept 2.1±3.6 cats; this number did not differ according to the presence of cat allergy, nor did the duration of cat ownership. Cat owners with a cat allergy had facial contact and slept with their cats less frequently (8.6±11.9 vs 18.3±27.0 times/day, Pcats shaved and beds cleaned less frequently than those without (1.8±3.3 vs 3.2±4.4 times/year, PCat owners with a cat allergy tried to minimize contact with their cats, but efforts to avoid indoor cat allergens were lower than those without. In comparison, dog owners with a dog allergy had kept their dogs for longer time than those without; however, current contact with their dogs and allergen avoidance measures did not differ between the 2 groups.

Hydrogen peroxide as a sustainable energy carrier: Electrocatalytic production of hydrogen peroxide and the fuel cell

Fukuzumi, Shunichi; Yamada, Yusuke; Karlin, Kenneth D.

2012-01-01

This review describes homogeneous and heterogeneous catalytic reduction of dioxygen with metal complexes focusing on the catalytic two-electron reduction of dioxygen to produce hydrogen peroxide. Whether two-electron reduction of dioxygen to produce hydrogen peroxide or four-electron O 2 -reduction to produce water occurs depends on the types of metals and ligands that are utilized. Those factors controlling the two processes are discussed in terms of metal–oxygen intermediates involved in the catalysis. Metal complexes acting as catalysts for selective two-electron reduction of oxygen can be utilized as metal complex-modified electrodes in the electrocatalytic reduction to produce hydrogen peroxide. Hydrogen peroxide thus produced can be used as a fuel in a hydrogen peroxide fuel cell. A hydrogen peroxide fuel cell can be operated with a one-compartment structure without a membrane, which is certainly more promising for the development of low-cost fuel cells as compared with two compartment hydrogen fuel cells that require membranes. Hydrogen peroxide is regarded as an environmentally benign energy carrier because it can be produced by the electrocatalytic two-electron reduction of O 2 , which is abundant in air, using solar cells; the hydrogen peroxide thus produced could then be readily stored and then used as needed to generate electricity through the use of hydrogen peroxide fuel cells.

2008-01-01

The ability of sulfate-reducing bacteria to produce hydrogen sulfide and the high affinity of sulfide to react with divalent metallic cations represent an excellent option to remove heavy metals from wastewater. Different parameters have been proposed to control the hydrogen sulfide production by anaerobic bacteria, such as the organic and sulfate loading rates and the feed COD/SO 4 2- ratio. This work relates the feed COD/SO 4 2- ratio with the hydrogen sulfide production and dissolved lead precipitation, using ethanol as carbon and energy source in an up-flow anaerobic sludge blanket reactor. A maximum dissolved sulfide concentration of 470 ± 7 mg S/L was obtained at a feed COD/SO 4 2- ratio of 2.5, with sulfate and ethanol conversions of approximately 94 and 87%, respectively. The lowest dissolved sulfide concentration (145 ± 10 mg S/L) was observed with a feed COD/SO 4 2- ratio of 0.67. Substantial amounts of acetate (510-1730 mg/L) were produced and accumulated in the bioreactor from ethanol oxidation. Although only incomplete oxidation of ethanol to acetate was observed, the consortium was able to remove 99% of the dissolved lead (200 mg/L) with a feed COD/SO 4 2- ratio of 1.5. It was found that the feed COD/SO 4 2- ratio could be an adequate parameter to control the hydrogen sulfide production and the consequent precipitation of dissolved lead

We study the behavior of hydrogen molecules between atomic-sized metallic electrodes using the mechanically controllable break junction technique. We focus on the interaction H{sub 2} with monoatomic gold chains demonstrating the possibility of a hydrogen molecule being incorporated in the chain. We also show that niobium is strongly reactive with hydrogen, which enables molecular transport studies between superconducting electrodes. This opens the possibility for a full characterization of the transmission properties of molecular junctions with superconducting subgap structure measurements.

An overview of the hydrogen related research presently undertaken at the Korea Atomic Energy Research Institute are presented. These encompass nuclear hydrogen production, hydrogen storage, and the safe handling of hydrogen, High temperature gas-cooled reactors can play a significant role, with respect to large-scale hydrogen production, if used as the provider of high temperature heat in fossil fuel conversion or thermochemical cycles. A variety of potential hydrogen production methods for high temperature gas-cooled reactors were analyzed. They are steam reforming of natural gas, thermochemical cycles, etc. The produced hydrogen should be stored safely. Titanium metal was tested primarily because its hydride has very low dissociation pressures at normal storage temperatures and a high capacity for hydrogen, it is easy to prepare and is non-reactive with air in the expected storage conditions. There could be a number of potential sources of hydrogen evolution risk in a nuclear hydrogen production facility. In order to reduce the deflagration detonation it is necessary to develop hydrogen control methods that are capable of dealing with the hydrogen release rate. A series of experiments were conducted to assess the catalytic recombination characteristics of hydrogen in an air stream using palladium catalysts. (author)
