What are the perceptions of parents of children with physical disabilities about the home exercise programs that physiotherapists prescribe? How do these perceptions affect adherence to home exercise programs? Qualitative study using focus groups and a modified grounded theory approach. Parents of children with physical disabilities who have been prescribed a home exercise program by physiotherapists. Twenty-eight parents participated in the focus groups. Two key themes that related to adherence to home exercise programs in young children with physical disabilities were identified: the characteristics of the home exercise program; and the characteristics of the physiotherapist's teaching style. In the first theme, the participants described their experiences regarding their preference for exercises, which was related to the perceived effects of the exercises, their complexity, and the number of exercises undertaken. These factors determined the amount of time spent performing the exercises, the effect of the exercises on the family's relationships, and any sense of related burden. In the second theme, participants revealed that they adhered better to prescribed exercises when their physiotherapist made an effort to build their confidence in the exercises, helped the parents to incorporate the home exercise program into their daily routine, provided incentives and increased motivation. Parents perceive that their children's adherence to home-based exercises, which are supervised by the parents, is more successful when the physiotherapist's style and the content of the exercise program are positively experienced. These findings reveal which issues should be considered when prescribing home exercise programs to children with physical disabilities.

Extracellular vesicles or microparticles exhibiting procoagulant and thrombogenic activity may contribute to the haemostatic potential of fresh frozen plasma. Fresh frozen plasma was prepared from platelet-rich plasma at 20 °C (Group-1 donors) or directly from whole blood at 4 °C (Group-2 donors). Each unit was aseptically divided into three parts, stored frozen for specific periods of time, and analysed by flow cytometry for procoagulant activity immediately after thaw or following post-thaw storage for 24 h at 4 °C. Donors' haematologic, biochemical and life-style profiles as well as circulating microparticles were analysed in parallel. Circulating microparticles exhibited a considerable interdonor but not intergroup variation. Fresh frozen plasma units were enriched in microparticles compared to plasma in vivo. Duration of storage significantly affected platelet- and red cell-derived microparticles. Fresh frozen plasma prepared directly from whole blood contained more residual platelets and more platelet-derived microparticles compared to fresh frozen plasma prepared from platelet-rich plasma. Consequently, there was a statistically significant difference in total, platelet- and red cell-derived microparticles between the two preparation protocols over storage time in the freezer. Preservation of the thawed units for 24 h at 4 °C did not significantly alter microparticle accumulation. Microparticle accumulation and anti-oxidant capacity of fresh frozen plasma was positively or negatively correlated, respectively, with the level of circulating microparticles in individual donors. The preparation protocol and the duration of storage in the freezer, independently and in combination, influenced the accumulation of microparticles in fresh frozen plasma units. In contrast, storage of thawed units for 24 h at 4 °C had no significant effect on the concentration of microparticles.

Physicochemical properties, sensory traits, and protein surface hydrophobicity of Chinese-style meatball (20% fat) processed from various combinations of xylooligosaccharides (XOS) and sucrose were investigated. No significant differences in pH and water-holding capacity were noted for treatments following cooking and frozen storage. Sensory springiness, hardness, chewiness, and overall acceptability of all treatments were found not significantly different. Water-soluble protein and total extractable protein concentrations of XOS4 (4% xylooligosaccharides) containing treatments were higher than other treatments at any frozen storage period (0, 4, 8, and 12 weeks). Addition of xylooligosaccharides or sucrose singly or in combination at levels investigated in this experiment resulted in Chinese meatballs with comparable quality. Substitution of sucrose with varying amounts (1, 2, and 4%) of xylooligosaccharides functioned equally on the quality of Chinese-style meatball. Copyright © 2011 Elsevier Ltd. All rights reserved.

Relationships between child-rearing styles and child behavior over time.

We investigate the hypothesis that "authoritarian" styles of child rearing will lead to more home and school problems than will "accommodative" styles. One hundred thirty-five children have been followed up from age 2 into first grade. Follow-up observations show no significant differences between groups on any of the scores indicating malfunctioning for boys or girls at home or school. However, the home behavior of boys being raised with accommodative styles was described in more positive terms by their mothers than those raised with authoritarian styles. The accommodatively raisded girls were described in more positive terms by their first grade teachers. We found no evidence in this study that the permissive style is producing large numbers of "spoiled brats" nor that the authoritarian styles are producing large numbers of overly aggressive or inhibited children. The way parents handle authority relationships is not sufficientyl predictive of later problems to warrant any widespread attempts by physicians to change them. The physician should respect individual differences in child-rearing syle and only intervene where there is substantial evidence that a particular approach is having a harmful effect.

Komer, Anne C; Jason, Leonard A; Harvey, Ronald; Olson, Brad

Oxford House recovery homes are unusual compared to most recovery homes in that they function entirely without the use of staff; instead members are elected to officer positions. The aim of this study was to perform preliminary analysis of the types of leadership styles utilized by members of oxford house. Twentynine house residents of five Oxford Houses were asked to rate their own leadership styles using the leader behavior description questionnaire and the multifactor leader questionnaire. Results showed that participants were more likely to use person-oriented behaviors above task-oriented actions. Transformational leadership was associated with higher outcomes than Transactional leadership. Implications for future research are discussed.

Despite the critical importance of successful recruitment and retention to study integrity, reporting of recruitment and retention strategies along with factors associated with successful recruitment and retention of participants in health-related interventions remain rare, especially for health and obesity prevention programs. Thus, the purpose of this article is to retrospectively examine the recruitment and retention marketing plan used in the online HomeStyles randomized controlled trial (RCT) and discuss outcomes associated with completion of the intervention. The HomeStyles RCT is an online intervention developed to motivate parents of young children to gain the skills and self-confidence needed to shape home environments and lifestyles to be protective against childhood obesity. Using the seven Ps of services marketing (i.e., people, place, product, physical evidence, price, promotion, and process), a comprehensive and systematic plan for recruitment and retention was implemented and outcomes assessed. A total of 489 parents with a young child aged 2 to attractiveness, interestingness, and usefulness. Despite all the retention efforts, the average monthly recruitment accrual rate of ~ 33 eligible enrolled participants at baseline (i.e., 489 participants/15-month recruitment period), declined to ~ 18, 11, 9, and 8 remaining recruited participants/month at midpoint, post, follow-up, and long-term follow-up surveys, respectively. In general, survey completers were significantly more likely to be female and perceived their child's health status to be better, and they were significantly less likely to be restrictive of their child's food intake. The findings of the present study highlight the need for far-reaching, concentrated, and varied recruitment strategies; sufficient time in the research plan for recruitment and retention activities; and creative, tireless, flexible, persistent project staff for health-related interventions.

In this study magnetic resonance was used to investigate magnetic fluid samples frozen under zero and non-zero (15 kG) external fields. The magnetite-based sample containing 2x10 17 particle/cm 3 was investigated from 100 to 400 K. Analysis of the temperature dependence of the resonance field revealed bigger magnetic structures in the frozen state than in the liquid phase. Also, differences in the mesoscopic organization in the frozen state may explain the data obtained from samples frozen under zero and non-zero fields

The global increase in childhood overweight and obesity has been ascribed partly to increases in children's screen time. Parents have a large influence on their children's screen time. Studies investigating parenting and early childhood screen time are limited. In this study, we investigated associations of parenting style and the social and physical home environment on watching TV and using computers or game consoles among 5-year-old children. This study uses baseline data concerning 5-year-old children (n = 3067) collected for the 'Be active, eat right' study. Children of parents with a higher score on the parenting style dimension involvement, were more likely to spend >30 min/day on computers or game consoles. Overall, families with an authoritative or authoritarian parenting style had lower percentages of children's screen time compared to families with an indulgent or neglectful style, but no significant difference in OR was found. In families with rules about screen time, children were less likely to watch TV>2 hrs/day and more likely to spend >30 min/day on computers or game consoles. The number of TVs and computers or game consoles in the household was positively associated with screen time, and children with a TV or computer or game console in their bedroom were more likely to watch TV>2 hrs/day or spend >30 min/day on computers or game consoles. The magnitude of the association between parenting style and screen time of 5-year-olds was found to be relatively modest. The associations found between the social and physical environment and children's screen time are independent of parenting style. Interventions to reduce children's screen time might be most effective when they support parents specifically with introducing family rules related to screen time and prevent the presence of a TV or computer or game console in the child's room.

Objectives were to characterize differences in pork bellies that were stored frozen for different durations prior to processing and characterize sensory properties of the bacon derived from those bellies when stored in either retail or food service style packaging. Bellies (n = 102) were collected from 4 different time periods, fresh bellies (never frozen) and bellies frozen for 2, 5, or 7 mo, and manufactured into bacon under commercial conditions. Food service bacon was packaged in oxygen-permeable polyvinyl lined boxes layered on wax-covered lined paper and blast frozen (-33 °C) for 45 or 90 d after slicing. Retail bacon was vacuum-packaged in retail packages and refrigerated (2 °C) in the dark for 60 or 120 d after slicing. At the end of respective storage times after slicing, bacon was analyzed for sensory attributes and lipid oxidation. Off-flavor and oxidized odor of bacon increased (P food service packaged bacon from frozen bellies, but was unchanged (P ≥ 0.07) with time in food service packaged bacon from fresh bellies. Lipid oxidation was also unchanged (P ≥ 0.21) over time in retail packaged bacon, with the exception of bellies frozen for 5 mo, which was increased from day 0 to day 90. Overall, off-flavor, oxidized odor, and lipid oxidation increased as storage time after processing increased. Freezing bellies before processing may exacerbate lipid oxidation as storage time after processing was extended. Bacon can be packaged and managed several different ways before it reaches the consumer. This research simulated food service (frozen) and retail packaged (refrigerated) bacon over a range of storage times after slicing. Off-flavor and oxidized odor increased as storage time after processing increased in both packaging types. Lipid oxidation increased as storage time after slicing increased to a greater extent in food service packaging. © 2014 Institute of Food Technologists®

Smart metering and in-home energy feedback; enabling a low carbon life style

Energy Technology Data Exchange (ETDEWEB)

Elburg, Henk van (SenterNovem (Netherlands)). e-mail: h.van.elburg@senternovem.nl

2009-07-01

Backed by raising energy demands, volatile oil prices and threat of climate change, the use of automated meter management (AMM), often referred to as 'smart metering', is rapidly gaining momentum across the world. Europe is expected to become a world leading centre of this development, thanks to the European Services Directive (ESD) of the European Commission. This Directive requires energy suppliers to provide consumers with competitively priced, accurate individual (smart) meters with information on time-of-use and accurate billing. Large scale deployments of smart meters have already been decided in Italy (Sweden) and The Netherlands. Serious considerations of implementing full smart metering penetration take place in countries like France, Ireland, Denmark and Finland. Oddly enough from an energy efficient life style point of view, a residential smart metering coverage alone does not automatically mean successful consumer involvement in general and enabling a lower carbon lifestyle in particular. These advantages require additional automation technologies 'beyond the meter', such as intuitive, aesthetic and affordable in-house displays and customized applications on web pages, cell phone or TV. To accelerate the development of contemporary 'add-on' information systems to keep pace with the deployment of smart meters, the technical and commercial in-home feedback innovations are being permanently reviewed in a worldwide selection of pioneering countries. At the eceee 2009 poster session, the latest insights regarding in-home communication to facilitate a modern energy efficient lifestyle will be revealed and an appealing, trendy and above all enabling in-house device will be presented.

Full Text Available Background. Assisted reproductive techniques have been used in China for more than 20 years. This study investigates the attitudes of surplus embryo holders towards embryos storage and donation for medical research. Methods. A total of 363 couples who had completed in vitro fertilization (IVF treatment and had already had biological children but who still had frozen embryos in storage were invited to participate. Interviews were conducted by clinics in a narrative style. Results. Family size was the major reason for participants’ (discontinuation of embryo storage; moreover, the moral status of embryos was an important factor for couples choosing embryo storage, while the storage fee was an important factor for couples choosing embryo disposal. Most couples discontinued the storage of their embryos once their children were older than 3 years. In our study, 58.8% of the couples preferred to dispose of surplus embryos rather than donate them to research, citing a lack of information and distrust in science as significant reasons for their decision. Conclusions. Interviews regarding frozen embryos, including patients’ expectations for embryo storage and information to assist them with decisions regarding embryo disposal, are beneficial for policies addressing embryo disposition and embryo donation in China.

Prajapati, Bhavna; Dunne, Mark; Bartlett, Hannah; Cubbidge, Robert

2011-01-01

This cross-sectional study was designed to determine whether the academic performance of optometry undergraduates is influenced by enrollment status, learning style or gender. Three hundred and sixty undergraduates in all 3 years of the optometry degree course at Aston University during 2008-2009 were asked for their informed consent to participate in this study. Enrollment status was known from admissions records. An Index of Learning Styles (http://www4.nscu.edu/unity/lockers/users/f/felder/public/Learning-Styles.html) determined learning style preference with respect to four different learning style axes; active-reflective, sensing-intuitive, visual-verbal and sequential-global. The influence of these factors on academic performance was investigated. Two hundred and seventy students agreed to take part (75% of the cohort). 63% of the sample was female. There were 213 home non-graduates (entrants from the UK or European Union without a bachelor's degree or higher), 14 home graduates (entrants from the UK or European Union with a bachelor's degree or higher), 28 international non-graduates (entrants from outside the UK or European Union without a bachelor's degree or higher) and 15 international graduates (entrants from outside the UK or European Union with a bachelor's degree or higher). The majority of students were balanced learners (between 48% and 64% across four learning style axes). Any preferences were towards active, sensing, visual and sequential learning styles. Of the factors investigated in this study, learning styles were influenced by gender; females expressed a disproportionate preference for the reflective and visual learning styles. Academic performance was influenced by enrollment status; international graduates (95% confidence limits: 64-72%) outperformed all other student groups (home non graduates, 60-62%; international non graduates, 55-63%) apart from home graduates (57-69%). Our research has shown that the majority of optometry students

Full Text Available Frank Schmid, Vladimir Jiranek School of Agriculture, Food and Wine, The University of Adelaide; and Wine Innovation Cluster, The Waite Campus, Glen Osmond, South Australia, Australia Background: This paper firstly examines the validity of using laboratory-scale fermentations as a means of correlating winemaking outcomes with larger industrial scale fermentations. Secondly, conventional and blast-freezing of whole bunches were investigated for their relative suitability as methods of preservation as determined by the nature of the resulting wines. Methods: Red must fermentations were compared at the laboratory 80 kg scale, and the more industrially representative 500 kg pilot scale. Fermentation profiles and duration for both scales were found to be very similar. Whole bunches were either slow/conventionally frozen (−20°C, or quickly/blast-frozen (−25°C. Results: Wines made from frozen grapes compared well with the wine made from the fresh must. Color and chemical analyses of the wines revealed few differences. A duo-trio sensory evaluation showed that wine from blast-frozen grapes was more similar to the fresh wines than wines from conventional frozen grapes. Conclusion: The findings of this research suggest that whole-bunch blast-freezing of grapes is preferable to conventional freezing. Keywords: wine color, research winemaking, frozen grapes

van der Horst, Klazine; Sleddens, Ester F C

2017-01-01

Toddlers' eating behaviors are influenced by the way parents interact with their children. The objective of this study was to explore how five major constructs of general parenting behavior cluster in parents of toddlers. These parenting clusters were further explored to see how they differed in the use of feeding strategies (i.e. feeding styles and food parenting practices) and by reported child eating styles. An online survey with 1005 mothers/caregivers (legal guardians) with at least one child between 12 and 36 months old was conducted in the United States in 2012, assessing general parenting behavior, feeding style, food parenting practices and the child eating styles. A three cluster solution of parenting style was found and clusters were labelled as overprotective/supervising, authoritarian, and authoritative. The clusters differed in terms of general parenting behaviors. Both overprotective and authoritative clusters showed high scores on structure, behavioral control, and nurturance. The overprotective cluster scored high on overprotection. The 'authoritarian' cluster showed lowest levels of nurturance, structure and behavioral control. Overprotective and authoritative parents showed very similar patterns in the use of food parenting practices, e.g. monitoring food intake, modeling, and promoting healthy food intake and availability at home. Overprotective parents also reported higher use of pressure to eat and involvement. Authoritarian parents reported high use of giving the child control over their food behaviors, emotion regulation, using food as a reward, and controlling food intake for weight control. Children's eating styles did not largely vary by parenting cluster. This study showed that a relatively new parenting style of overprotection is relevant for children's eating behaviors. Overprotective parents reported food parenting practices that are known to be beneficial for children's food intake, such as modelling healthy food intake, as well as

The clusters differed in terms of general parenting behaviors. Both overprotective and authoritative clusters showed high scores on structure, behavioral control, and nurturance. The overprotective cluster scored high on overprotection. The 'authoritarian' cluster showed lowest levels of nurturance, structure and behavioral control. Overprotective and authoritative parents showed very similar patterns in the use of food parenting practices, e.g. monitoring food intake, modeling, and promoting healthy food intake and availability at home. Overprotective parents also reported higher use of pressure to eat and involvement. Authoritarian parents reported high use of giving the child control over their food behaviors, emotion regulation, using food as a reward, and controlling food intake for weight control. Children's eating styles did not largely vary by parenting cluster.This study showed that a relatively new parenting style of overprotection is relevant for children's eating behaviors. Overprotective parents reported food parenting practices that are known to be beneficial for children's food intake, such as modelling healthy food

Parenting style influences a child's overall diet quality and establishes food preferences. Parenting style and "food rules" for children differ by eating at home or away from home. Eating meals away from home is increasing despite associations with consumption of unhealthy foods and higher weight status. The objective of the current study was to compare parenting practices and decision-making at restaurants versus at home. A mixed methods approach was utilized: facilitated, individual interviews to explore decision-making and parenting practices; written questionnaires for socio-demographic information; and body mass index. Summaries and emergent themes were generated based on examination of tapes and transcripts. Descriptive statistics were computed for questionnaire data. Twenty-five mothers of children of five to eight years who ate at restaurants at least two times per week participated. Mothers reported more permissive food rules at restaurants yet maintained higher behavioral expectations. Mothers were also more likely to make decisions about whether they eat out, where to eat, and children's meal selections than their children. The findings suggest that parenting practices toward overall behavior and food choices may differ at restaurants than at home, highlighting the importance of healthy menu options, further research, and educational strategies.

The Eccentric Behavior of Nearly Frozen Orbits

Science.gov (United States)

Sweetser, Theodore H.; Vincent, Mark A.

2013-01-01

Frozen orbits are orbits which have only short-period changes in their mean eccentricity and argument of periapse, so that they basically keep a fixed orientation within their plane of motion. Nearly frozen orbits are those whose eccentricity and argument of periapse have values close to those of a frozen orbit. We call them "nearly" frozen because their eccentricity vector (a vector whose polar coordinates are eccentricity and argument of periapse) will stay within a bounded distance from the frozen orbit eccentricity vector, circulating around it over time. For highly inclined orbits around the Earth, this distance is effectively constant over time. Furthermore, frozen orbit eccentricity values are low enough that these orbits are essentially eccentric (i.e., off center) circles, so that nearly frozen orbits around Earth are bounded above and below by frozen orbits.

Relationships between parenting style, feeding style and feeding practices and fruit and vegetable consumption in early childhood.

Science.gov (United States)

Blissett, Jackie

2011-12-01

Despite substantial evidence suggesting that a diet high in fruit and vegetables (FV) is associated with reduced risk of cancer, only 21% of children in the UK consume the recommended 5 portions of fruit or vegetables a day. This review examines the role of parenting style, feeding style and feeding practices in FV consumption in early childhood. Whilst inconsistencies in concepts and terminology cloud this literature, overall the evidence suggests that the context of an authoritative parenting and feeding style is associated with better FV consumption in the childhood years. This context is typified by emotional warmth but high expectations for children's dietary adequacy and behaviour, accompanied by specific feeding practices such as modeling consumption of FV, making FV available within the home, covertly restricting unhealthy alternative snack foods, and encouraging children to try FV. Further longitudinal and intervention studies are required to determine the efficacy of modification of parenting style and feeding practice on children's FV intake. Copyright © 2011 Elsevier Ltd.

2014-02-01

In the past, several studies have suggested the existence of a "periarthritic personality" in patients with frozen shoulder. We conducted a study to determine differences in personality traits in patients with primary and secondary frozen shoulders. We prospectively evaluated 118 patients (84 women and 34 men; mean age, 53.8 years; SD 7.56) with a frozen shoulder. Of these patients, 48 had an idiopathic frozen shoulder and 70 had a secondary frozen shoulder. Personality traits were determined by the NEO Five-Factor Inventory (NEO-FFI) scale. This questionnaire measures the 5 major personality traits and is based on the norms determined in a neutral test situation for 2415 controls. Compared with healthy controls, no differences in personality traits were found in patients with primary and secondary frozen shoulder, except for Conscientiousness and Extraversion, for which patients with secondary frozen shoulder scored significantly higher than healthy controls. Patients with primary frozen shoulder scored significantly higher on Openness to Experience than did patients with secondary frozen shoulder; on the other 4 Big Five personality traits, no significant differences were found between patients with primary and secondary frozen shoulder. More specifically, patients with idiopathic frozen shoulder did not score higher on the trait Neuroticism as would be expected from previous publications. Our study results do not indicate that patients with an idiopathic frozen shoulder have a specific personality compared with healthy controls. Only a few differences were found in personality traits when the entire frozen shoulder group was compared with healthy controls and between patients with primary and secondary frozen shoulders. The results of this study suggest that these differences are not sufficient to speak about a specific "frozen shoulder personality."

Full Text Available The final quality of fish meat depends on the chemical and microbiological quality of fish at the time of freezing as well as on other factors including storage temperature and freezing rate. Analysis of chemical composition (water, protein and fat content, expressible drip, total volatile nitrogen levels, microbiological analyses (total viable counts, Enterobacteriaceae, psychrotrophic bacteria and histological examinations on dorsal skeletal muscles were carried out to distinguish fresh, frozen and double frozen rainbow trout (Oncorhynchus mykiss. Significantly higher expressible drip and total volatile base nitrogen concentrations (P Enterobacteriaceae and psychrotrophic bacteria were determined in double frozen trout. The light microscopy of fresh trout muscles did not show any microstructural changes, whereas deformations of muscle fibres and optically empty areas were found in frozen trout. Remarkable defects of the muscle structure in double frozen trout were demonstrated and total disruption of muscle fibres was found. The freezing of trout resulted in various structural changes in the dorsal skeletal musculature. This is a first study comparing changes in fresh, frozen and repeatedly frozen trout. Chemical, microbiological and subsequent histological examinations can be used for revealing the foul practices confusing the consumer with offering thawed fish instead of fresh cooled fish.

To observe the biomechanical properties difference between fresh frozen bone and fresh frozen pasteurized bone process Thirty eight femurs bones taken from 6 years old primate.(macaca fascicularis) from Primate Nursery Center LIPI Bogor, 20 bones were 6 cm cut for bending test and 18 remains were 3 cm cut for compression test. All bones were frozen and then divided into two groups for each biomechanical study. First group (I 0 bones for bending test and 9 bones for compression test) were undergone fresh frozen procession only. The second group with the same amount was undergone fresh frozen and pasteurized on 60 degree C for three hours. Bending test was done until the bones were broken on control group and pasteurized group and the result was compared, the same procedure was done for compression test. The study was done in room temperature. The biomechanical test result was analyzed by two independent T tests. The bending test control group has ( mean 0.097 N / mm sup 2 (SD = 0.007) and the pasteurized group ( mean 0. I 0 1 N / mm sup 2 (SD = 0.0 1 3), there was no significant difference (p 0.399). The compression test control group has ( = mean 0.71 N / mm sup 2 (SD=0.128)where as the pasteurized group has(mean 0.50N/mm sup 2 (SD=0.111),there was significant difference (p =0.004) From the result biomechanical study on bending test, there was no significant difference of bone strength, whereas on compression test the fresh frozen with pasteurized bone group is 125% stronger than control group. The result of this study will be very useful for reconstruction bone allograft

Reading Processes and Parenting Styles.

Carreteiro, Rui Manuel; Justo, João Manuel; Figueira, Ana Paula

Home literacy environment explains between 12 and 18.5 % of the variance of children's language skills. Although most authors agree that children whose parents encourage them to read tend to develop better and earlier reading skills, some authors consider that the impact of family environment in reading skills is overvalued. Probably, other variables of parent-child relationship, like parenting styles, might be relevant for this field. Nevertheless, no previous studies on the effect of parenting styles in literacy have been found. To analyze the role of parenting styles in the reading processes of children. Children's perceptions of parenting styles contribute significantly to the explanation of statistical variance of children's reading processes. 110 children (67 boys and 43 girls), aged between 7 and 11 years (M [Formula: see text] 9.22 and SD [Formula: see text] 1.14) from Portuguese schools answered to a socio-demographic questionnaire. To assess reading processes it was administered the Portuguese adaptation (Figueira et al. in press) of Bateria de Avaliação dos Processos Leitores-Revista (PROLEC-R). To assess the parenting styles Egna Minnen av Barndoms Uppfostran-parents (EMBU-P) and EMBU-C (children version) were administered. According to multiple hierarchical linear regressions, individual factors contribute to explain all reading tests of PROLEC-R, while family factors contribute to explain most of these tests. Regarding parenting styles, results evidence the explanatory power about grammatical structures, sentence comprehension and listening. Parenting styles have an important role in the explanation of higher reading processes (syntactic and semantic) but not in lexical processes, focused by main theories concerning dyslexia.

After five years of using our unique "school style" technique, we were able to increase the number of home discharges and decrease the number of days spent in the facility. In order to identify the factors underlying these results, a survey was conducted regarding changes of the physical and cognitive function while in the facility. The subjects included 41 patients who newly began using our facility. All subjects participated in both group and individual programs and were evaluated using the Mini Mental State Examination (MMSE), Frontal Assessment Battery at the bedside (FAB), Vitality Index and Functional Independence Measure (FIM) determined monthly starting the first day of entry into our facility. We compared the results using the Friedman test. The rate of participation in the group program was 81.9%. The average duration of participation in functional training as an individual program was 5.94 days, while that for Kumon learning therapy was 3.27 days. Effective improvements were noted in all four evaluation measurements: MMSE・FAB・Vitality Index・FIM. Improvements in the physical and cognitive function were obtained despite the status of the subjects as elderly individuals with chronic disease. Against this background, we applied interventions with rehabilitation using an intensive program for individuals and noted a pleasant experience during all activities in our unique "school style" protocol, which seeks to improve the subject's motivation. These factors are therefore important for improving the physical and cognitive function.

Cerina, Veronica; Fornara, Ferdinando; Manca, Sara

2017-09-01

The purpose of this study was to analyse the effects of residential facilities' design features on older adults' psychosocial responses. Participants ( N  = 192) were over 65-year-old residents who were randomly exposed to different experimental scenarios concerning a hypothetical residential facility for older adults, using a 3 × 2 between-subjects design (i.e. home-like vs. hotel-like vs. usual-standard architectural style; presence vs. absence of green spaces). After the experimental session, participants were asked to fill in a questionnaire that measured their attitudes towards short- and long-term relocation, anticipated residential satisfaction with the facility, and feelings of broken home attachment. The results showed (1) more positive responses to "home-like" and "hotel-like" architectural styles than the usual-standard type and (2) the positive impact of green spaces on the assessment of the facilities. These design features should thus play a role in both reducing the stressful impact of leaving home and promoting beneficial patterns, hence fostering "successful ageing".

Fertility test of frozen boar semen.

1976-10-01

The fertility results of two experiments are presented. In experiment 1, the semen was frozen in tris-fructose-EDTA or BF3 diluents at 0-25 X 10(9)/ml sperm concentration and extended after thawing with either seminal plasma (SP) or the freezing medium (FM) containing no cryoprotective agent. In the second experiment the semen was glycerolated by two methods, frozen at 1-0 X 10(9)/ml sperm concentration, and extended wtih FM before insemination. Fertility after double insemination within one oestrus with semen frozen in tris-fructose-EDTA or BF3 diluents varied depending on the medium used for extension of thawed semen. The farrowing rates for semen frozen in the former diluent with FM and SP post-thawing media were 4/8 and 1/8 respectively, and for semen frozen BF3 diluent with FM and SP post-thawing extenders 1/8 and 5/8. The mean farrowing for the 32 animals inseminasted was 34-4%. Pregnancies for semen frozen in tris-fructose-EDTA and glycerolated at 30 or 5 degrees C were 5/12 and 4/12 respectively, and for single and double inseminations 6/12 and 3/12 respectively. Of 24 animals inseminated 37-5% farrowed.

This study examined the effectiveness of manipulation under ultrasound-guided brachial plexus block in patients with recalcitrant idiopathic frozen shoulder and diabetic secondary frozen shoulder (diabetic frozen shoulder). Forty-four idiopathic frozen shoulders and 10 diabetic frozen shoulders with failed conservative treatment for at least 3 months were included in this study. The manipulation was performed under ultrasound-guided brachial plexus block and visual analogue scale, range of motion, and Constant scores were measured before manipulation and at the last follow-up examination. No major complications were observed during the procedure. Sufficient improvement was not obtained in two patients during the procedure and to avoid complications, the procedure was discontinued and subsequently arthroscopic capsular release was performed. Visual analogue scale, range of motion towards all directions, and Constant scores were significantly improved after the manipulation in both the idiopathic frozen shoulder and diabetic frozen shoulder groups, however the diabetic group showed inferior results compared with those of the idiopathic group. This manipulation was effective and shortened the duration of symptoms in most of the idiopathic and diabetic frozen shoulders without major complications during the procedure. Diabetic frozen shoulder showed inferior clinical results and difficulty in recovery in range of motion, which indicated that diabetic frozen shoulder should be discussed as a different entity.

Leadership, staffing and quality of care in nursing homes

2011-01-01

Background Leadership and staffing are recognised as important factors for quality of care. This study examines the effects of ward leaders' task- and relationship-oriented leadership styles, staffing levels, ratio of registered nurses and ratio of unlicensed staff on three independent measures of quality of care. Methods A cross-sectional survey of forty nursing home wards throughout Norway was used to collect the data. Five sources of data were utilised: self-report questionnaires to 444 employees, interviews with and questionnaires to 13 nursing home directors and 40 ward managers, telephone interviews with 378 relatives and 900 hours of field observations. Separate multi-level analyses were conducted for quality of care assessed by relatives, staff and field observations respectively. Results Task-oriented leadership style had a significant positive relationship with two of the three quality of care indexes. In contrast, relationship-oriented leadership style was not significantly related to any of the indexes. The lack of significant effect for relationship-oriented leadership style was due to a strong correlation between the two leadership styles (r = 0.78). Staffing levels and ratio of registered nurses were not significantly related to any of the quality of care indexes. The ratio of unlicensed staff, however, showed a significant negative relationship to quality as assessed by relatives and field observations, but not to quality as assessed by staff. Conclusions Leaders in nursing homes should focus on active leadership and particularly task-oriented behaviour like structure, coordination, clarifying of staff roles and monitoring of operations to increase quality of care. Furthermore, nursing homes should minimize use of unlicensed staff and address factors related to high ratios of unlicensed staff, like low staff stability.

2003-08-01

The importance of the social environment for dietary behaviour has been highlighted in the past decade. A type of environmental influence that has received increasing research attention in recent years is the influence that parents can have on their children's dietary behaviour through food-related parenting practices. Much of the work done so far, however, has reported inconsistent findings and poorly understood mechanisms of influence. The present study aimed to explore the possible environmental influence of general parenting style on adolescent food choice patterns. Data were collected at schools (N=643; mean age 16.5 years), using self-administered questionnaires on parenting style, fruit intake behaviour and fruit-specific cognitions. Consistent and theoretically predictable differences were found between adolescents who described their parents as authoritative, authoritarian, indulgent or neglectful. Fruit consumption and fruit-specific cognitions were most favourable among adolescents who were being raised with an authoritative parenting style. Children of parents with indulgent parenting styles consumed more fruit than adolescents from authoritarian or neglectful homes. Consequences of these results for the interpretation of earlier studies on the influence of parenting practices are discussed, and a research model is proposed for future studies of parental influences on adolescent dietary behaviours.

Frozen section diagnosis provides critical information for immediate surgical management decision making. Over the last several years, there have been some significant advances in treatment of genitourinary cancer, particularly with regard to surgical techniques. These changes in turn impact the type and frequency of intraoperative frozen section requests. In this review, we describe the main indications and diagnostic challenges of frozen section diagnosis during surgeries of each genitourinary organ system including prostate, kidney, bladder, testis, and penis. The pitfalls and approaches to different diagnostic situations are discussed. It is also stressed that pathologists must not only be familiar with the histological diagnosis, but also understand the limitations of frozen section diagnosis and communicate with urologists during the intraoperative treatment decision making process.

We propose and test a model connecting women's attachment styles, intimate relationship quality, workplace supervisor relationships, and well-being. The factors that lead to women's successful interaction patterns at home with a partner are suggested to be similar to successful interactions at work and are suggested to be related to well-being. A model was tested with data from 209 working women across various U.S. organizations. Women with an avoidance attachment style tended to have intimate relationships that were low in satisfaction and cohesion as well as low-quality relationships with their supervisors. Women in cohesive intimate relationships were likely to be satisfied with their job, experience low conflict at work, and report few physical symptoms. Women who had quality relationships with their superiors also had low conflict at work and were satisfied with their jobs. Results show important associations among social relationships at home and work related to quality of life.

The possible use of gamma irradiation at doses of 1.6 to 4.0 kGy to improve bacteriological quality of frozen chicken was investigated. The effects of gamma irradiation on salmonella viability in frozen chicken and on sensory quality of frozen chicken were also evaluated. D 10 -values for different isolated strains of salmonella in frozen chicken varied from 0.41 to 0.57 kGy. A dose of 4 kGy is required for a seven log cycle reduction of salmonella contamination in frozen chicken. Approximately 21 per cent of frozen chicken examined were contaminated with salmonella. Salmonella typhimurium, salmonella virchow, and salmonella java were predominant. Irradiation of frozen chicken at a minimum dose of 3.2 kGy eliminated salmonella, coliform, Escherichia coli, and Staphylococcus aureus and, in addition, reduced baterial load by 2 log cycles. Faecal streptococci was still present in a 3.2 kGy samples but in a very small percentage and the count was not over 100 colonies per g. Discoloring of chicken meat was noted after a 2 kGy treatment. The sensory quality of frozen chicken irradiated at 3 and 4 kGy tended to decrease during frozen storage but was within the acceptable range on a nine point hedonic scale even after eight months of frozen storage. Dosage at 3.2 kGy appeared to be sufficient for improving bacteriological quality of frozen chicken

Exposure of frozen mincemeat samples to gamma radiation reduced the initial total bacterial count (8.5x10 5 ) by 0.6, 1.5, 2.9 and 3.6 log cycles, when 2, 4, 6 and 8 kGy doses were applied, respectively. Irradiation, even at the lowest dose applied (2 kGy). destroyed almost the pathogenic and indicator bacteria contaminated mincemeat samples. During frozen storage (-18 degree), the microbial population slightly decreased. No organoleptic of spoilage were detected throughout the storage period (6 months) in irradiated samples receiving doses up to 8 kGy and frozen storage (-18 degree C) of mincemeat for 6 months had no effect on the major constituents of these products (moisture, protein and lipids). Irradiation dose could be increased up to 8 kGy in case of deep frozen mincemeat stored for long period, without any detectable effect upon the acceptability of the product. In the same time 8 kGy is considered quite sufficient to decontaminate potentially pathogens from frozen mincemeat samples. On the basis of economic consideration and the results of this study, 4 kGy could be recommended for irradiation of frozen mincemeat

The frozen pie production has a lot of defects resulting in high production cost. Failure mode and effect analysis (FMEA) technique has been applied to improve the frozen pie process. Pareto chart is also used to determine the major defects of frozen pie. There are 3 main processes that cause the defects which are the 1st freezing to glazing process, the forming process, and the folding process. The Risk Priority Number (RPN) obtained from FMEA is analyzed to reduce the defects. If RPN of each cause exceeds 45, the process will be considered to be improved and selected for the corrective and preventive actions. The results showed that RPN values decreased after the correction. Therefore, the implementation of FMEA technique can help to improve the performance of frozen pie process and reduce the defects approximately 51.9%.

Full Text Available BACKGROUND The aim of this prospective randomized control study is to compare the functional outcome between hydrodilatation and intraarticular steroid injection in patients with primary frozen shoulder. MATERIALS AND METHODS A total number of 52 patients who attended the orthopaedic outpatient between November 2014 and January 2016 were included in this study. The patients were categorized into two groups. Group I patients were treated with hydrodilatation method and Group II patients were treated with intra-articular steroids. Both the group of patients were advised to perform home exercise programs. The patients were assessed at baseline (before the procedure at two weeks, six weeks, three months and six months. All patients were evaluated for functional improvement by measuring the range of active movements and Constant and Murley shoulder outcome scores. RESULTS Up to three months patients treated with hydrodilatation have significantly better functional outcome as evaluated by active range of movements and Constant and Murley score. But at six months there is no significant difference in functional outcome between two methods of treatment. CONCLUSION There was improvement in functional outcome in both the methods of treatment. But patients treated by hydrodilatation showed more significant increase in functional outcome for the first three months. Home exercise forms an integral part in the management of primary frozen shoulder.

Full Text Available Because of technological advancements and the popularity of the Internet, online shopping has become an important shopping channel for consumers. Because people increasingly eat out, more consumers shop online, and food products are collected from convenience stores, or frozen food home delivery services are used. This study used questionnaire surveys to analyze the consumption habits of residents who shop online for frozen foods in the urban areas of northern Taiwan (Taipei City and New Taipei City. We distributed and collected 548 questionnaires, of which 484 were valid. Descriptive statistics, a chi-square test, and logistics regression analysis were used to analyze consumer characteristics, as well as important influential factors. The research results indicated that most online shoppers were women, and the top 3 factors influencing their purchasing decisions were freshness, delivery convenience, and ordering convenience. Participants in the age group of 40-49 years old, living in the urban area of New Taipei City, without junior college education, and with less than 10,000 NTD monthly incomes, were less likely to purchase frozen foods using low-temperature logistics services.

Death rates due to hypertension in low and middle income countries are higher compared to high income countries. The present study is designed to combine life style modification and home blood pressure monitoring for control of hypertension in the context of low and middle income countries. The study is a two armed, parallel group, un-blinded, cluster randomized controlled trial undertaken within lower income areas in Kuala Lumpur. Two housing complexes will be assigned to the intervention group and the other two housing complexes will be allocated in the control group. Based on power analysis, 320 participants will be recruited. The participants in the intervention group (n = 160) will undergo three main components in the intervention which are the peer support for home blood pressure monitoring, face to face health coaching on healthy diet and demonstration and training for indoor home based exercise activities while the control group will receive a pamphlet containing information on hypertension. The primary outcomes are systolic and diastolic blood pressure. Secondary outcome measures include practice of self-blood pressure monitoring, dietary intake, level of physical activity and physical fitness. The present study will evaluate the effect of lifestyle modification and peer support home blood pressure monitoring on blood pressure control, during a 6 month intervention period. Moreover, the study aims to assess whether these effects can be sustainable more than six months after the intervention has ended.

Parenting styles influence a child's risk for obesity. The goals of this study are to evaluate the influence of (i) parenting style on children's health behaviors (physical activity and dietary intake), (ii) children's sociodemographic characteristics on parenting style and on children's health behaviors and (iii) parents' sociodemographic characteristics on their use of controlling styles to promote a healthy home environment. Survey and anthropometric data were collected from a community sample of Latino parents (n = 812) and their children in kindergarten through second grade. Parental use of positive reinforcement and monitoring was associated with children's healthy eating and exercise. Also, parents' use of appropriate disciplining styles was associated with healthier eating, while parental use of control styles was associated with unhealthy eating. The daughters of parents who used controlling styles ate more unhealthy foods than did the sons. Older, employed and more acculturated parents used less controlling styles than their counterparts. Parenting interventions targeting children's dietary intake and physical activity should encourage parents to use more positive reinforcement and monitor their children's health behaviors as these parenting styles are associated with healthier behaviors. Moreover, intervention researchers may want to encourage Latino parents to use less controlling styles with girls as this parenting style increased girls' risk for unhealthy eating.

Full Text Available The present study examined the relationships between dispositional approach and avoidance motives, humor styles, and happiness. In keeping with previous research, approach motives and the two positive humor styles (self-enhancing and affiliative positively correlated with happiness, whereas avoidance motives and the two negative humor styles (self-defeating and aggressive negatively correlated with happiness. Also, we found support for three new hypotheses. First, approach motives correlated positively with self-enhancing and affiliative humor styles. Second, avoidance motives correlated positively with self-defeating humor style, and third, the positive relationship between approach motives and happiness was mediated by self-enhancing humor style.

To examine (1) the relationships between job satisfaction and task- and relationship-oriented leadership and (2) the direct and moderating effects on job satisfaction of three ward-level factors: workload, use of teams and staff stability. Job satisfaction in nursing homes is vital to meeting the challenges related to recruitment and turnover. Cross-sectional design. A multilevel analysis approach was used to recognise a hierarchal structure of determined factors and to capture variation in job satisfaction at the individual and ward level. A questionnaire was sent to 444 registered nurses, auxiliary nurses and unskilled nursing assistants. Structured interviews were administered to 40 ward managers and 13 directors, and 900 hours of field observations was conducted in 40 nursing home wards throughout Norway. We found a significant relationship between job satisfaction and task-oriented and relationship-oriented leadership styles, with a stronger effect for task orientation. The effect of the two leadership styles varied significantly across wards. Furthermore, staff stability had both a significant positive direct effect and a moderating effect on job satisfaction, whereas the two other ward-level predictors yielded no significant contributions. The relatively stronger effect of task-oriented leadership on job satisfaction, particularly in wards with low staff stability, is in contrast to most previous studies and suggests that there may be specific conditions in nursing homes that favour the use of this leadership style. The varying effect of both leadership styles indicates that staff in different nursing home wards could benefit from the use of different leadership styles. The study highlights the importance of using different leadership behaviour and the importance of high staff stability to ensure job satisfaction among nursing home personnel. © 2011 Blackwell Publishing Ltd.

2010-03-01

Full Text Available In this study, a frozen soil parameterization has been modified and incorporated into a distributed biosphere hydrological model (WEB-DHM. The WEB-DHM with the frozen scheme was then rigorously evaluated in a small cold area, the Binngou watershed, against the in-situ observations from the WATER (Watershed Allied Telemetry Experimental Research. First, by using the original WEB-DHM without the frozen scheme, the land surface parameters and two van Genuchten parameters were optimized using the observed surface radiation fluxes and the soil moistures at upper layers (5, 10 and 20 cm depths at the DY station in July. Second, by using the WEB-DHM with the frozen scheme, two frozen soil parameters were calibrated using the observed soil temperature at 5 cm depth at the DY station from 21 November 2007 to 20 April 2008; while the other soil hydraulic parameters were optimized by the calibration of the discharges at the basin outlet in July and August that covers the annual largest flood peak in 2008. With these calibrated parameters, the WEB-DHM with the frozen scheme was then used for a yearlong validation from 21 November 2007 to 20 November 2008. Results showed that the WEB-DHM with the frozen scheme has given much better performance than the WEB-DHM without the frozen scheme, in the simulations of soil moisture profile at the cold regions catchment and the discharges at the basin outlet in the yearlong simulation.

Frozen orbit realization using LQR analogy

Science.gov (United States)

Nagarajan, N.; Rayan, H. Reno

In the case of remote sensing orbits, the Frozen Orbit concept minimizes altitude variations over a given region using passive means. This is achieved by establishing the mean eccentricity vector at the orbital poles i.e., by fixing the mean argument of perigee at 90 deg with an appropriate eccentricity to balance the perturbations due to zonal harmonics J2 and J3 of the Earth's potential. Eccentricity vector is a vector whose magnitude is the eccentricity and direction is the argument of perigee. The launcher dispersions result in an eccentricity vector which is away from the frozen orbit values. The objective is then to formulate an orbit maneuver strategy to optimize the fuel required to achieve the frozen orbit in the presence of visibility and impulse constraints. It is shown that the motion of the eccentricity vector around the frozen perigee can be approximated as a circle. Combining the circular motion of the eccentricity vector around the frozen point and the maneuver equation, the following discrete equation is obtained. X(k+1) = AX(k) + Bu(k), where X is the state (i.e. eccentricity vector components), A the state transition matrix, u the scalar control force (i.e. dV in this case) and B the control matrix which transforms dV into eccentricity vector change. Based on this, it is shown that the problem of optimizing the fuel can be treated as a Linear Quadratic Regulator (LQR) problem in which the maneuver can be solved by using control system design tools like MATLAB by deriving an analogy LQR design.

Currently, the progresses on treatment of musculoskeletal diseases with the evolving of artificial implants and the success of tissue transplantation between genetically different individuals have conducted to an increase in radiosterilization. Regarding to tissue transplantation, it is essential to have sterile tissue and many tissue banks use radiosterilization as an effective method to sterilize these tissues. However, high doses of ionizing radiation and the preservation method may induce structural modifications in the tissues, as degradation of structural scaffold, decreasing its mechanical properties. Particularly, cartilage have been preserved in high concentrations of glycerol or deep-frozen at -70 degree C for storage after radiosterilization. Therefore, it is important to study the modifications induced in cartilage by preservation methods and by radiosterilization to determine the appropriated parameters for high quality of human allografts. Costal cartilages were obtained from cadaveric donors and were frozen at -20 degree C for 2 years long in order to compare with previous studies for fresh, deep-frozen and glycerolised cartilages. The mechanical tests were carried out in a universal testing machine until sample failure. According our results, there is no significant statistical difference between stress at break of fresh, long-term - 20 degree C frozen cartilages and deep-frozen cartilage. This early result suggests, regarding to tensile property, that long-term - 20 degree C frozen cartilages corresponds to glycerolised costal cartilages irradiated with 25 kGy or deep-frozen cartilages irradiated with 25 and 50 kGy. Thus, this long-term frozen cartilages may be used for tissue banks, but more studies about effects of ionizing radiation are necessary. (author)

Nowadays, consumer demand is driving better and more nutritious dairy products. Changing from traditional to new lactose-free products poses technological challenges for the food industry in order to maintain or improve their food characteristics and consumer preferences. This study investigates the production of lactose-free frozen yogurt by enzymati- cally hydrolysis of lactose, and its influence on the final product characteristics. In the case of lactose-free products, commercial Ha-lactase® was used for hydrolysis, and the reaction occurred simultaneously with fermentation. The effect of lactose hydrolysis on the physicochemical properties, texture, viscosity, overrun and sensory attributes in the final product was investigated. After yogurt maturation, the acidity of the lactose-free product was significantly higher than in the control, suggesting that breaking down lactose enhances the fermentation process. Lactose-free frozen yogurt had significantly lower hardness and stickiness and higher viscosity than control frozen yogurt. Moreover, lactose hydrolysis promoted a smooth and creamy consistency, whereas in the case of conventional prod- ucts a coarse structure, due to the presence of large ice crystals, was identified. Hydrolysis of lactose also improved the sweetness and brightness of frozen yogurt. The improved textural properties of lactose-free product results from the fact that monosaccharides produced during lactose hydrolysis depress the freezing point of the mix, which enables product with softer structure and bigger resistance to ice recrystallization to be obtained. The study showed that lactose-free frozen yogurt may be used successfully for production of novel lactose-free frozen desserts. Lactose hydrolysis improves the texture and viscosity of the product,     as well as enhancing its sensory quality.

To better understand whether the parental food controlling practices pressure and restriction to eat are obesity preventing or obesity promoting, this study examined whether these parenting practices are related to other (food or non-food) areas that are generally regarded as obesogenic or leptogenic. Are these foods controlling practices more indicative of obesogenic or leptogenic child life style behaviors? In a sample of 7-12-year-old boys and girls (n = 943) the perceived parental food controlling practices were related to various measures for unhealthy life style. Using factor analysis we assessed whether there is a constellation of lifestyle behaviors that is potentially obesogenic or leptogenic. Remarkably, perceived parental restriction and pressure loaded on two different factors. Perceived parental restriction to eat had a negative loading on a factor that further comprised potential obesogenic child life style behaviors, such as snacking (positive loading), time spend with screen media (television or computer) (positive loadings) and frequency of fruit consumption (negative loading). Perceived parental pressure to eat had a positive loading on a factor that further comprised potential leptogenic life style behaviors such as frequency of eating a breakfast meal and sporting (positive loadings). It is concluded that low perceived parental restriction in regard to food may perhaps be a sign of more uninvolved 'neglecting' or indulgent parenting/obesogenic home environment, whereas high perceived parental pressure to eat may be sign of a more 'concerned' leptogenic parenting/home environment, though more research into style of parenting is needed.

A prolonged outbreak of Salmonella enterica serotype Enteritidis occurred in northern France between December 2014 and April 2015. Epidemiological investigations following the initial notification on 30 December 2014 of five cases of salmonellosis (two confirmed S. Enteritidis) in young children residing in the Somme department revealed that all cases frequented the same food bank A. Further epidemiological, microbiological and food trace-back investigations indicated frozen beefburgers as the source of the outbreak and the suspected lot originating from Poland was recalled on 22 January 2015. On 2 March 2015 a second notification of S. Enteritidis cases in the Somme reinitiated investigations that confirmed a link with food bank A and with consumption of frozen beefburgers from the same Polish producer. In the face of a possible persistent source of contamination, all frozen beefburgers distributed by food bank A and from the same origin were blocked on 3 March 2015. Microbiological analyses confirmed contamination by S. Enteritidis of frozen beefburgers from a second lot remaining in cases' homes. A second recall was initiated on 6 March 2015 and all frozen beefburgers from the Polish producer remain blocked after analyses identified additional contaminated lots over several months of production.

Modeling snowmelt infiltration in seasonally frozen ground

Budhathoki, S.; Ireson, A. M.

2017-12-01

In cold regions, freezing and thawing of the soil govern soil hydraulic properties that shape the surface and subsurface hydrological processes. The partitioning of snowmelt into infiltration and runoff has also important implications for integrated water resource management and flood risk. However, there is an inadequate representation of the snowmelt infiltration into frozen soils in most land-surface and hydrological models, creating the need for improved models and methods. Here we apply, the Frozen Soil Infiltration Model, FroSIn, which is a novel algorithm for infiltration in frozen soils that can be implemented in physically based models of coupled flow and heat transport. In this study, we apply the model in a simple configuration to reproduce observations from field sites in the Canadian prairies, specifically St Denis and Brightwater Creek in Saskatchewan, Canada. We demonstrate the limitations of conventional approaches to simulate infiltration, which systematically over-predict runoff and under predict infiltration. The findings show that FroSIn enables models to predict more reasonable infiltration volumes in frozen soils, and also represent how infiltration-runoff partitioning is impacted by antecedent soil moisture.

Background Research on family meals in the last decade has shown a positive association between family meal frequency and adolescent healthy dietary intake. However, less is known about factors within the home environment, such as parenting style, which may be associated with family meal patterns. Objective The purpose of this study is to test cross-sectional and five-year longitudinal associations between parenting styles (authoritative, authoritarian, permissive, neglectful) and the frequency of family meals among adolescents. Study Design Data were from Project EAT (Eating Among Teens), a population-based study comprised of youth from diverse ethnic/racial and socioeconomic backgrounds. Two cohorts of adolescents (middle school, high school) completed in-class surveys in 1999 (Time 1) and mailed surveys in 2004 (Time 2). Multiple linear regression models were used to predict mean frequency of family meals at Time 1 and Time 2 from adolescent report of parenting style (both mother and father) at Time 1. Cross-sectional analyses included both adolescent cohorts (n = 4,746) and longitudinal analyses included only the younger cohort (n = 806) because family meal frequency was not assessed in the older cohort at Time 2. Results Cross-sectional results for adolescent girls indicated a positive association between maternal and paternal authoritative parenting style and frequency of family meals. For adolescent boys, maternal authoritative parenting style was associated with more frequent family meals. Longitudinal results indicated that authoritative parenting style predicted higher frequency of family meals five years later, but only between opposite sex parent/adolescent dyads. Conclusions Future research should identify additional factors within the home environment that are associated with family meal frequency in order to develop effective interventions that result in increased family meals for youth. Also, future research should investigate the mealtime behaviors

Cross-sectional results for adolescent girls indicated a positive association between maternal and paternal authoritative parenting style and frequency of family meals. For adolescent boys, maternal authoritative parenting style was associated with more frequent family meals. Longitudinal results indicated that authoritative parenting style predicted higher frequency of family meals 5 years later, but only between opposite sex parent/adolescent dyads. Future research should identify additional factors within the home environment that are associated with family meal frequency to develop effective interventions that result in increased family meals for youth. Also, future research should investigate the mealtime behaviors of authoritative parents and identify specific behaviors that dietetics

Nursing homes are becoming increasingly complex clinical environments because of rising resident acuity and expansion of postacute services within a context of historically poor quality performance. Discrete quality markers have been linked to director of nursing (DON) leadership behaviors. However, the impact of DON leadership across all measured areas of DON jurisdiction has not been tested using comprehensive domains of quality deficiencies. The aim of this study was to examine the effects of DON leadership style including behaviors that facilitate the exchange of information between diverse people on care quality domains through the lens of complexity science. Three thousand six hundred nine DONs completed leadership and intent-to-quit surveys. Quality markers that were deemed DON sensitive included all facility survey deficiencies in the domains of resident behaviors/facility practices, quality of life, nursing services, and quality of care. Logistic regression procedures estimated associations between variables. The odds of deficiencies for all DON sensitive survey domains were lower in facilities where DONs practiced complexity leadership including more staff input and shared decisional authority. DON quit intentions were aligned with higher odds of facility deficiencies across all domains. Results supported the hypotheses that DONs using complexity leadership approaches by interacting more freely with staff, discussing resident issues, and sharing decision making produced better care outcomes from every DON sensitive metric assessed by Centers for Medicare and Medicaid Services. The mechanism linking poor quality with high DON quit intentions is an area for future research. Encouraging DON use of complexity leadership approaches has the potential to improve a broad swath of quality outcomes.

Frozen dairy products have characteristics of both yogurt and ice cream and could be the persuasive carriers of probiotics. Functions of the frozen yogurt containing viable bifidobacterial cells are recognized and favored by the people of all ages. We developed a kind of yogurt supplemented by Bifidobacterium species. Firstly, five strains of Bifidobacterium spp. ( Bifidobacterium bifidum ATCC 11547, Bifidobacterium longum ATCC 11549, Bifidobacterium infantis ATCC 11551, Bifidobacterium adolescentis ATCC 11550, and Bifidobacterium breve ATCC 11548) were evaluated based on the feasibility criteria of probiotics, comprising acid production, bile tolerance, and adhesion to epithelial cells. Formerly, we combined the optimum strains with yogurt culture ( Lactobacillus delbrueckii subsp. bulgaricus EMCC 11102 and Streptococcus salivarius subsp. thermophilus EMCC 11044) for producing frozen yogurt. Finally, physiochemical properties and sensory evaluation of the frozen yogurt were investigated during storage of 60 days at -18°C. Results directed that Bifidobacterium adolescentis ATCC 11550 and Bifidobacterium infantis ATCC 11551 could be utilized with yogurt culture for producing frozen yogurt. Moreover, the frozen yogurt fermented by two bifidobacterial strains and yogurt culture gained the high evaluation in the physiochemical properties and sensory evaluation. In summary, our results revealed that there was no significant difference between frozen yogurt fermented by Bifidobacterium spp. and yogurt culture and that fermented by yogurt culture only.

Frozen southern bluefin tuna meat discolors easily and sometimes contracts when thawed caused by thaw rigor. These phenomenon often become problematic in the transaction or handling of this kind of frozen tuna. Frozen meat blocks of southern Bluefin tuna were thawed separately by air thawing, running water thawing and microwave thawing. Changes occurring during thawing were checked for meat color by met-myoglobin ratio determination and for contract by microscopic observation. Results are as follows : (1) Discoloration scarcely occurred in the process of running water thawing (at 10°C for 50 min, or at 0°C for 6 hr). (2) No contraction was observed during thawing with running water described above and air thawing (at 18-20°C for 6 hr). (3) Discoloration and contraction seemed to be minimized, as to latently contractile blocks, when meat temperature passed through rapidly between -10°C and -5°C, and slowly (for 5-6 hr) between -5°C and -1°C. When the block was originally not contractile, discloration was minimized by rising meat temperature rapidly from -10°C to -l°C.

2004-03-01

A 4-year-review was carried out on intraoperative frozen section consultations in Sultanah Aminah Hospital, Johor Bahru. Two hundred and fifteen specimens were received from 79 patients in the period between January 1999 and December 2002. An average of 2.72 specimens per patient was received. The overall diagnostic accuracy was high, 97.56%. The diagnoses were deferred in 4.65% of the specimens. False positive diagnoses were made in 3 specimens (1.46%) and false negative diagnoses in 2 specimens (0.98%). This gave an error rate of 2.44%. The main cause of error was incorrect interpretation of the pathologic findings. In the present study, frozen sections showed good sensitivity (97.98%) and specificity (97.16%). Despite its limitations, frozen section is still generally considered to be an accurate mode of intraoperative consultation to assist the surgeon in deciding the best therapeutic approach for his patient at the operating table. The use of frozen section with proper indications was cost-effective as it helped lower the number of reoperations. An audit of intraoperative frozen section from time to time serves as part of an ongoing quality assurance program and should be recommended where the service is available.

Researches on the Constitutive Models of Artificial Frozen Silt in Underground Engineering

Directory of Open Access Journals (Sweden)

Yugui Yang

2014-01-01

Full Text Available The researches on the mechanical characteristic and constitutive models of frozen soil have important meanings in structural design of deep frozen soil wall. In the present study, the triaxial compression and creep tests have been carried out, and the mechanical characteristic of frozen silt is obtained. The experiment results show that the deformation characteristic of frozen silt is related to confining pressure under conventional triaxial compression condition. The frozen silt presents strain softening in shear process; with increase of confining pressure, the strain softening characteristic gradually decreases. The creep curves of frozen silt present the decaying and the stable creep stages under low stress level; however, under high stress level, once the strain increases to a critical value, the creep strain velocity gradually increases and the specimen quickly happens to destroy. To reproduce the deformation behavior, the disturbed state elastoplastic and new creep constitutive models of frozen silt are developed. The comparisons between experimental results and calculated results from constitutive models show that the proposed constitutive models could describe the conventional triaxial compression and creep deformation behaviors of frozen silt.

To present a case of ligneous conjunctivitis where the recurrence of membranous conjunctivitis was prevented by subconjunctival and topical instillation of fresh frozen plasma. Interventional case report. A case of ligneous conjunctivitis with multiple recurrences since the age of 3 years developed recurrent membranous conjunctivitis after transconjunctival levator recession. Blood plasminogen activity was determined. The membrane was excised, and the membrane reappeared 4 days later. The patient was treated with excision of the membrane and subconjunctival injection of fresh frozen plasma and topical fresh frozen plasma. Plasminogen activity of the fresh frozen plasma was normal. Plasminogen blood functional activity was 52% (normal is 80%-120%). The patient had complete remission with no recurrences of membranous conjunctivitis after topical and subconjunctival fresh frozen plasma. Prophylactic use of topical and subconjunctival fresh frozen plasma may help in the prevention of membranes in susceptible patients with plasminogen deficiency.

Twelve samples of imported frozen shrimps were used in this study. The total aerobic bacteria were at 2 × 10 4 to 6 × 10 6 per gram. A few of Vibrio parahaemolyticus, V. mimicus, V. alginolyticus, V. vulnificus, V. fluvialis and Listeria monocytogenes were isolated from many samples. However, Salmonella was not detected in any of the samples. After exposure to 4-5 kGy of gamma-rays, the total aerobic bacteria in frozen shrimps were reduced by approximately 2-3 log cycles. The dose necessary to reduce the vibrio isolates and Aeromonas hydrophila at a level of below 10 -4 per gram was about 3 kGy in frozen shrimps, whereas about 3.5 kGy was required for L. monocytogenes and Salmonella typhimurium. In this study, unpleasant off-odor was clearly detected in the non-frozen shrimps irradiated at 2.5 kGy. On the other hand, off-odor was negligible in the frozen product below 5 kGy irradiation. No remarkable changes of peroxide values were also obtained up to 9 kGy of irradiation in the frozen shrimps. However peroxide values of non-frozen shrimps were clearly increased even irradiated at 4 kGy. Trimethylamine content was not changed at doses below 10 kGy in both of frozen and non-frozen shrimps. Shelf-life of defrosted shrimps were extended ca. 2 times under non-frozen market conditions.

the aim of this study was to identify the incidence of surgical treatment for frozen shoulder in a western population. patients included in this study all resided within a well-defined area in the North West of England, all had surgery for frozen shoulder over a 3-year period and were identified from theatre logbooks of two local hospitals. Cases having surgery for shoulder stiffness other than frozen shoulder were excluded. Local and national population size estimates were based on data obtained from the UK Office for National Statistics. 117 patients underwent surgery for frozen shoulder during the period examined; of these 101 had arthroscopic arthrolysis and 16 had manipulation under anaesthesia. The overall incidence of frozen shoulder surgery was calculated at 2.67 procedures per 10,000 general population per year, and at 7.55 for those aged 40-60. surgical intervention for frozen shoulder is common, estimated at over 14,180 cases per year in England. Given the variation in costs associated with arthroscopic arthrolysis and manipulation under anaesthesia, comparative studies of the cost effectiveness of the two procedures would be of great value. 2C (outcome research).

Gas pipelines buried in permafrost are subjected to the mechanisms of frost heave and thaw settlement which induce movement in the pipe. The magnitude of loads depend on the relative displacement and the load-displacement characteristics of the surrounding soils. This paper presented the results of laboratory tests that investigated the geomechanical properties and uplift resistance of frozen Calgary silt. Compacted soil was frozen 24 hours prior to the uplift testing. A thick-wall steel pipe was laid down and more soil was subsequently placed and compacted around and above the pipe until the desired burial depth was achieved. The temperature of the frozen soil was monitored along with deformations of the soil surface in order to determine the impact of loading rate, ice content and freezing direction. The geomechanical tests included triaxial compression tests as well as tensile and creep tests. The stiffness, tensile strain limits and time dependent behaviour of the frozen soil were also defined. The issue of crack development in the frozen soil was addressed and a numerical model was developed based on measured load-displacement relationships and geomechanical properties of the frozen soil. Bilinear stress-strain relationships were consistently noted for the frozen samples under triaxial compression. The stress-strain behaviour was found to be independent of the confining stress. The measured tensile limits were found to be in good agreement with published literature. Peak uplift resistance and post-peak decreases were consistently noted in the uplift resistance. Tensile fractures were observed vertically above the crown of the pipe. Uplift resistance was highly affected by the loading rate, but the load-displacement curve prior to the peak was not affected by radial freezing or ice lenses. A new peak uplift resistance was reached following the freeze/thaw cycle, suggesting the healing of the tensile fractures. 9 refs., 1 tab., 11 figs.

Full Text Available Learner diversity that exists in the classroom plays a role in influencing the teaching and learning process in the classroom. It should be acknowledged in order for the teaching and learning process to be a meaningful and effective process. Thus, this study examined the learning styles preference of engineering students and the teaching styles preferences of their Technical Communication lecturers. The study also looked at whether the students’ learning styles preferences were influenced by their field of study, gender and ethnic backgrounds. Felder and Solomon’s Index of Learning Styles was administered to 588 engineering students while Grasha and Riechmann-Hruska’s Teaching Style Survey was administered to 10 Technical Communication lecturers. The findings revealed that the students have a marked preference for the visual learning style but balanced preferences for the other learning styles dimensions. The students’ field of study, gender and ethnic backgrounds did not seem to influence the students’ learning styles preferences. As for their Technical Communication lecturers, they seem to favour the student-centered teaching approach. All the data support the notion of adopting a balanced teaching approach in the Technical Communication classroom.

Sometimes, drug product for parenteral administration is stored in a frozen state (e.g., -20 °C or -80 °C), particularly during early stages of development of some biotech molecules in order to provide sufficient stability. Shipment of frozen product could potentially be performed in the frozen state, yet possibly at different temperatures, for example, using dry ice (-80 °C). Container closure systems of drug products usually consist of a glass vial, rubber stopper, and an aluminum crimped cap. In the frozen state, the glass transition temperature (Tg) of commonly used rubber stoppers is between -55 and -65 °C. Below their Tg, rubber stoppers are known to lose their elastic properties and become brittle, and thus potentially fail to maintain container closure integrity in the frozen state. Leaks during frozen temperature storage and transportation are likely to be transient, yet, can possibly risk container closure integrity and lead to microbial contamination. After thawing, the rubber stopper is supposed to re-seal the container closure system. Given the transient nature of the possible impact on container closure integrity in the frozen state, typical container closure integrity testing methods (used at room temperature conditions) are unable to evaluate and thus confirm container closure integrity in the frozen state. Here we present the development of a novel method (thermal physical container closure integrity) for direct assessment of container closure integrity by a physical method (physical container closure integrity) at frozen conditions, using a modified He leakage test. In this study, different container closure systems were evaluated with regard to physical container closure integrity in the frozen state to assess the suitability of vial/stopper combinations and were compared to a gas headspace method. In summary, the thermal physical container closure integrity He leakage method was more sensitive in detecting physical container closure

Role of frozen section in surgery of benign thyroid

2007-04-01

Full Text Available Background: Fine-needle aspiration biopsy can very reliably discriminate between benign and malignant thyroid tumors. The role of additional intraoperative frozen section to guide intraoperative management was questioned.Methods: A retrospective analysis of all thyroid resections at our department between 2000 and 2004 was performed.Results: 420 patients with benign thyroid lesions underwent surgical resections. 169 lobectomies and 251 total thyroidectomies were performed and 57 (13.5 % thyroid cancers discovered (mostly papillary carcinomas. 54 frozen sections were performed and sensitivity rate of 11.1 % and specificity rate of 97.8 % was estimated.Conclusions: Our data supports the fact that intraoperative frozen section is not sensitive enough to substantially add to preoperative fine-needle aspiration biopsy, even with more selective use. We conclude that routine use of frozen section is not cost-effective in surgery of the benign thyroid and can therefore be abandoned.

Hypervelocity Launching and Frozen Fuels as a Major Contribution to Spaceflight

Science.gov (United States)

Cocks, F. H.; Harman, C. M.; Klenk, P. A.; Simmons, W. N.

Acting as a virtual first stage, a hypervelocity launch together with the use of frozen hydrogen/frozen oxygen propellant, offers a Single-Stage-To-Orbit (SSTO) system that promises an enormous increase in SSTO mass-ratio. Ram acceleration provides hypervelocity (2 km/sec) to the orbital vehicle with a gas gun supplying the initial velocity required for ram operation. The vehicle itself acts as the center body of a ramjet inside a launch tube, filled with gaseous fuel and oxidizer, acting as an engine cowling. The high acceleration needed to achieve hypervelocity precludes a crew, and it would require greatly increased liquid fuel tank structural mass if a liquid propellant is used for post-launch vehicle propulsion. Solid propellants do not require as much fuel- chamber strengthening to withstand a hypervelocity launch as do liquid propellants, but traditional solid fuels have lower exhaust velocities than liquid hydrogen/liquid oxygen. The shock-stability of frozen hydrogen/frozen oxygen propellant has been experimentally demonstrated. A hypervelocity launch system using frozen hydrogen/frozen oxygen propellant would be a revolutionary new development in spaceflight.

It was shown that ice storage of muscle samples before they were frozen and thawed resulted in a major freezing-induced activation of cytochrome oxidase activity. The enzyme may therefore be used...... as an indicator of frozen fish to determine if the fish has been stored on ice before freezing. Cytochrome oxidase activity showed also potential as an indicator of frozen storage, as it was possible to distinguish between the frozen storage temperatures -9, -20, and -40 degreesC....

Cooking time, yield, and palatability of paired beef, pork, and lamb roasts cooked from the frozen and thawed states were compared. Cooking time for all roasts averaged from 3 to 22 min. per pound longer for meat cooked from the frozen state. The longer cooking time from the frozen state. The longer cooking time from the frozen state was greater for roasts with a large amount of bone and for cuts cooked by braising than for less bony roasts and cuts cooked by roasting. Except for thawed beef rump roasts, which had a higher yield of cooked lean meat, yield of cooked lean meat from the various cuts of beef, pork, and lamb was not affected by the state at the start of cooking. Collectively, all pork roasts had a higher yield of cooked lean meat when cooked from the frozen state. Juiciness and natural flavor of the roasts were not affected by the state at the start of cooking. Lamb leg and rib roasts were more tender when cooked from the thawed state.

Quality of non-irradiated and irradiated frozen shrimp after shipping trial from Thailand to the Netherlands were investigated. Commercial frozen shell on headless shrimp and pre-cooked and peeled shrimp were irradiated with 0, 2, and 3 kGy at the Office of Atomic Energy for Peace (OAEP), Thailand, and transported by sea to the International Facility for Food Irradiation Technology (IFFIT), the Netherlands. It was found that both types of frozen shrimp before shipment are of good quality. Radiation with 3 kGy resulted in 2-3 log cycles reduction of mesophilic and psychrotrophic colony counts and caused no significant change in sensory quality. The irradiated products were found to be free from coliforms, faecal coliforms, Escherichia coli, salmonella, vibrio parahaemolyticus and Staphylococcus aureus. There was no increase in bacterial count in irradiated frozen shrimps after two months of transportation. The results of flora analysis show that radiation does not present any hazard resulting from a shift in the microflora. The surviving microflora in both types of irradiated frozen shrimp consisted mainly of Micrococcus spp.. Besides, irradiation with dose of 3 kGy did not affect the sensory quality of the frozen shrimp within duration of transportation. It can be concluded that irradiation improves the bacteriological quality of frozen shrimp for transportation to the Netherlands

-analysis. A mixed-treatment comparison (MTC) was also undertaken. An economic decision model was intended, but was found to be implausible because of a lack of available evidence. Resource use was estimated from clinical advisors and combined with quality-adjusted life-years obtained through mapping to present tentative cost-effectiveness results. Thirty-one clinical effectiveness studies and one economic evaluation were included. The clinical effectiveness studies evaluated steroid injection, sodium hyaluronate, supervised neglect, physical therapy (mainly physiotherapy), acupuncture, MUA, distension and capsular release. Many of the studies identified were at high risk of bias. Because of variation in the interventions and comparators few studies could be pooled in a meta-analysis. Based on single RCTs, and for some outcomes only, short-wave diathermy may be more effective than home exercise. High-grade mobilisation may be more effective than low-grade mobilisation in a population in which most patients have already had treatment. Data from two RCTs showed that there may be benefit from adding a single intra-articular steroid injection to home exercise in patients with frozen shoulder of analysis was based on only a subset of the evidence, which may explain why the findings are only partly supportive of the main analysis. No studies of patients' views about the treatments were identified. Average costs ranged from £36.16 for unguided steroid injections to £2204 for capsular release. The findings of the mapping suggest a positive relationship between outcome and European Quality of Life-5 Dimensions (EQ-5D) score: a decreasing visual analogue scale score (less pain) was accompanied by an increasing (better) EQ-5D score. The one published economic evaluation suggested that low-grade mobilisation may be more cost-effective than high-grade mobilisation. Our tentative cost-effectiveness analysis suggested that steroid alone may be more cost-effective than steroid plus

In June this year, delegates from more than 30 Antarctic Treaty nations met and agreed on a set of rules under the 'Convention on the Regulation of Antartic Mineral Resource Activities'. The convention presents a legal basis for mining which previously did not exist but it requires the two-third approval of a regulatory committee comprising countries both with and without territorial claims. However, the environment of the Antarctic is so harsh that very few in the international mining industry consider mining in the frozen continent a viable proposition.

Full Text Available Fresh date fruits, especially Barhi cultivar, are favored and widely consumed at the Khalal maturity stage (first color edible stage. These fruits are seasonal and perishable and there is a need for extending their shelf life. This study evaluates two different freezing methods, namely cryogenic freezing using liquid nitrogen and conventional deep freezing on preserving the quality and stability of date fruits (cv. Barhi at Khalal maturity stage. Fresh date fruits (cv. Barhi at Khalal stage were frozen utilizing the two methods. The produced frozen dates were stored under frozen storage conditions for nine months (at −20 °C and −40 °C for the conventional and cryogenic freezing, respectively. Color values, textural properties (hardness, elasticity, chewiness and resilience, and nutrition attributes (enzymes and sugars for fresh dates before freezing and for the frozen dates were measured every three months during the frozen storage. Color values of the frozen dates were affected by the freezing method and the frozen storage period. There are substantial differences in the quality of the frozen fruits in favor of cryogenic freezing compared to the conventional slow freezing. The results revealed a large disparity between the times of freezing of the two methods. The freezing time accounted to 10 min in the cryogenic freezing method, whereas it was 1800 min for the conventional slow freezing system.

The occurrence of yeasts on ripe fruits and frozen pulps of pitanga (Eugenia uniflora L), mangaba (Hancornia speciosa Gom.), umbu (Spondias tuberosa Avr. Cam.), and acerola (Malpighia glaba L) was verified. The incidence of proteolytic, pectinolytic, and mycocinogenic yeasts on these communities was also determined. A total of 480 colonies was isolated and grouped in 405 different strains. These corresponded to 42 ascomycetous and 28 basidiomycetous species. Candida sorbosivorans, Pseudozyma antarctica, C. spandovensis-like, C. spandovensis, Kloeckera apis, C. parapsilosis, Rhodotorula graminis, Kluyveromyces marxianus, Cryptococcus laurentii, Metchnikowia sp (isolated only from pitanga ripe fruits), Issatchenkia occidentalis and C. krusei (isolated only from mangaba frozen pulps), were the most frequent species. The yeast communities from pitanga ripe fruits exhibited the highest frequency of species, followed by communities from acerola ripe fruits and mangaba frozen pulps. Yeast communities from frozen pulp and ripe fruits of umbu had the lowest number of species. Except the yeasts from pitanga, yeast communities from frozen pulp exhibited higher number of yeasts than ripe fruit communities. Mycocinogenic yeasts were found in all of the substrates studied except in communities from umbu ripe fruits and pitanga frozen pulps. Most of the yeasts found to produce mycocins were basidiomycetes and included P. antarctica, Cryptococcus albidus, C. bhutanensis-like, R. graminis and R. mucilaginosa-like from pitanga ripe fruits as well as black yeasts from pitanga and acerola ripe fruits. The umbu frozen pulps community had the highest frequency of proteolytic species. Yeasts able to hydrolyse casein at pH 5.0 represented 38.5% of the species isolated. Thirty-seven percent of yeast isolates were able to hydrolyse casein at pH 7.0. Pectinolytic yeasts were found in all of the communities studied, excepted for those of umbu frozen pulps. The highest frequency of

Style in Music

Science.gov (United States)

Dannenberg, Roger B.

Because music is not objectively descriptive or representational, the subjective qualities of music seem to be most important. Style is one of the most salient qualities of music, and in fact most descriptions of music refer to some aspect of musical style. Style in music can refer to historical periods, composers, performers, sonic texture, emotion, and genre. In recent years, many aspects of music style have been studied from the standpoint of automation: How can musical style be recognized and synthesized? An introduction to musical style describes ways in which style is characterized by composers and music theorists. Examples are then given where musical style is the focal point for computer models of music analysis and music generation.

Full Text Available Objective The study aimed at assessing the effects of frozen storage duration on quality characteristics, lipid oxidation and sensory quality of various horse muscles. Methods Five representative muscles: longissimus dorsi (LD, gluteus medius (GM, semimembranosus (SM, biceps femoris (BF, and triceps brachii (TB at 24 h post-mortem obtained from 28-mo-old Jeju female breed horses (n = 8 were used in the present investigation. The muscles were vacuum-packaged and frozen at −20°C for 120, 240, and 360 days. All the samples were analyzed for thawing and cooking losses, pH, Warner–Bratzler shear forces (WBSF, color traits, total volatile basic nitrogen (TVBN, thiobarbituric acid reactive substances (TBARS and sensory traits. The muscle samples analyzed on day 0 of frozen storage (fresh, non-frozen were used for comparison. Results Results revealed that thawing and cooking losses significantly (p<0.05 increased in all the muscles after 120 days and then remained unchanged up to 360 days of frozen storage. The TBARS and TVBN contents significantly increased as increasing frozen storage time up to 360 days (p<0.05. While, significant decreases in WBSF values were observed for all the muscles with increased frozen storage time (p<0.05. Frozen storage variously affected the color traits of the muscles for instance; the redness of LD, GM, and BF muscles showed a decreasing tendency during frozen storage while it was not changed in TB and SM muscles. Furthermore, the frozen storage did not produce detrimental effects on sensory quality as it did not cause flavor and juiciness defects whereas it partially improved the tenderness of all the muscles studied. Conclusion Based on the results obtained from our work, it is concluded that frozen storage could be applied to increase the long-term shelf life of horsemeat while still retaining its sensory quality.

Little research exists about the factors influencing the foods available at family meals. This study examines the home food environment factors contributing to the presence of fruit and vegetables at family meals. Home food inventory (HFI) and survey data were collected from low-income, minority families (n = 120) with children 6-12 years old. Observations from video-recorded family dinner meals, totaling 800 videos, were used to measure the frequency at which fruit and vegetables were served. Multiple regression was used to investigate how the fruit and vegetables in the HFI and other home food environment factors were related to the number of days fruit and vegetables were served at dinner during the observation period. Availability and accessibility of fruit and vegetables in the home were each found to be significantly associated with the presence of fruits and vegetables at family dinners. Of the fruit and vegetable categories (i.e., fresh, canned, or frozen), having fresh fruit and vegetables available in the home was found to be most strongly associated with serving fruit and vegetables at dinner, respectively. Higher parent intake of vegetables was associated with the presence of vegetables at dinners, and parent meal planning was associated with the presence of fruit at dinners. Increasing the availability and accessibility of fresh fruit and vegetables in the home may be an effective approach to increasing the presence of fruits and vegetables at family dinners, especially among low-income, minority households. It is also essential to understand why families are not using all fruits and vegetables (e.g., canned and frozen) available in the home for family meals. Family meals are a place to promote the increased presence of both fruit and vegetables. Copyright © 2015 Elsevier Ltd. All rights reserved.

Frozen shoulder has not previously been shown to be associated with infection. The present study set out to confirm the null hypothesis that there is no relationship between infection and frozen shoulder using two modern scientific methods, extended culture and polymerase chain reaction (PCR) for bacterial nucleic acids. A prospective cohort of 10 patients undergoing arthroscopic release for stage II idiopathic frozen shoulder had two biopsies of tissue taken from the affected shoulder joint capsule at the time of surgery, along with control biopsies of subdermal fat. The biopsies and controls were examined with extended culture and PCR for microbial nucleic acid. Eight of the 10 patients had positive findings on extended culture in their shoulder capsule and, in six of these, Propionibacterium acnes was present. The findings mean that we must reject the null hypothesis that there is no relationship between infection and frozen shoulder. More studies are urgently needed to confirm or refute these findings. If they are confirmed, this could potentially lead to new and effective treatments for this common, painful and disabling condition. Could P. acnes be the Helicobacter of frozen shoulder?

Experimental Analysis and Discussion on the Damage Variable of Frozen Loess

Directory of Open Access Journals (Sweden)

Cong Cai

2017-01-01

Full Text Available The damage variable is very important to study damage evolution of material. Taking frozen loess as an example, a series of triaxial compression and triaxial loading-unloading tests are performed under five strain rates of 5.0 × 10−6–1.3 × 10−2/s at a temperature of −6°C. A damage criterion of frozen loess is defined and a damage factor Dc is introduced to satisfy the requirements of the engineering application. The damage variable of frozen loess is investigated using the following four methods: the stiffness degradation method, the deformation increase method, the dissipated energy increase method, and the constitutive model deducing method during deformation process. In addition, the advantages and disadvantages of the four methods are discussed when they are used for frozen loess material. According to the discussion, the plastic strain may be the most appropriate variable to characterize the damage evolution of frozen loess during the deformation process based on the material properties and the nature of the material service.

Just the word “telecommuter” is enough to make many managers start to sweat. When faced with the prospect of managing an employee they cannot even see, basic managerial knowledge often becomes hazy, resulting in a confusing arrangement for both manager and employee. As more and more of our world revolves around technology and an increasing number of jobs can be executed from an office at home , managers must learn how to adapt their leadership style to cater to both remote employees, and those working in the office.(1)   As the policy concerning working from home is described in the Operational Circular No 7(2), I will not describe it in detail but rather focus on the pros and cons of such a work arrangement, and most importantly on the discussion following a request and on the necessary mutual confidence between the manager and the employee.

Stiffness Evolution in Frozen Sands Subjected to Stress Changes

KAUST Repository

Dai, Sheng; Santamarina, Carlos

2017-01-01

Sampling affects all soils, including frozen soils and hydrate-bearing sediments. The authors monitor the stiffness evolution of frozen sands subjected to various temperature and stress conditions using an oedometer cell instrumented with P-wave transducers. Experimental results show the stress-dependent stiffness of freshly remolded sands, the dominant stiffening effect of ice, creep after unloading, and the associated exponential decrease in stiffness with time. The characteristic time for stiffness loss during creep is of the order of tens of minutes; therefore it is inevitable that frozen soils experience sampling disturbances attributable to unloading. Slow unloading minimizes stiffness loss; conversely, fast unloading causes a pronounced reduction in stiffness probably attributable to the brittle failure of ice or ice-mineral bonding.

The authors monitor the stiffness evolution of frozen sands subjected to various temperature and stress conditions using an oedometer cell instrumented with P-wave transducers. Experimental results show the stress-dependent stiffness of freshly remolded sands, the dominant stiffening effect of ice, creep after unloading, and the associated exponential decrease in stiffness with time. The characteristic time for stiffness loss during creep is of the order of tens of minutes; therefore it is inevitable that frozen soils experience sampling disturbances attributable to unloading. Slow unloading minimizes stiffness loss; conversely, fast unloading causes a pronounced reduction in stiffness probably attributable to the brittle failure of ice or ice-mineral bonding.

Objective: To investigate the relationship between parenting styles and family communication patterns with adolescent's quality of life. Methods: The cross-sectional study was carried out on 439 randomly selected adolescents in the city of Zahedan, Iran, from January to July 2011. The subjects were asked to complete the KIDSCREEN-52 health-related quality of life questionnaire, while their parents were asked to complete the Diana Brinder's Test to show their parenting styles. SPSS 15 was used to analyse data. Results: Most parents had authoritative parenting style (n=380; 86.6%). Pluralistic (n=170; 38.7%) and consensual (n=152; 34.6%) patterns were the most frequent styles of communication in families. Data suggested a significant relationship between parenting style and some dimensions of quality of life, including physical well-being, psychological well-being, social support and peers, and autonomy (p<0.05). There was also a significant relationship between family communication patterns and parent relation and home life (p<0.001) as well as autonomy (p<0.006). Conclusion: Families play a critical role in increasing adolescents, health-related quality-of-life. Effort should be made to address problems facing parents while raising their children. (author)

This study was carried out to evaluate the chemical changes in short-bodied mackerel during chilled (4 degree Celcius) and frozen (-18 degree Celicus) storage for 18 days. The chemical changes were monitored at three days interval using Peroxide Value (PV), Thiobarbituric Acid (TBA), Total Volatile Base Nitrogen (TVBN) and Trimethylamine (TMA) tests. The PV of both chilled and frozen mackerel significantly increased (p<0.05) with storage time and the rate was significantly higher in chilled than frozen mackerel. Based on the results, the chilled and frozen mackerel started to become rancid at day 15 and day 18, respectively. Similar trend was observed for TBA value, where the malonaldehyde content significantly increased (p<0.05) for both chilled and frozen mackerel with storage time, and the rate of increase was higher in chilled than frozen mackerel. The TVBN and TMA of chilled mackerel increased significantly during storage time, but the values declined in frozen mackerel which might be due to inhibitory effects of freezing on the bacterial activities and hence avoid accumulation of TMA. Based on the chemical analyses, chilled mackerel spoiled rapidly compared to frozen mackerel. (author)

Accuracy of frozen section in borderline ovarian tumor

Full Text Available Borderline ovarian tumor or low malignant ovarian tumor presents in 10-15% of all ovarian cancers, which usually affects younger women and have favorable prognosis even with conservative surgery, in which fertility can be preserved. Lack of reliable diagnostic tool to indicate the type of malignancy before or at the time of surgery makes the borderline ovarian tumor one of the most controversial topics in gynecology. This might lead to many overtreatment cases with radical surgery or undertreatment with conservative surgery with the higher rate of overtreatment compared to under treatment.In this review article, we extensively searched for all reported data regarding the accuracy of frozen section in borderline ovarian tumor. Reviewing the results of six studies, which specifically considered the accuracy of frozen section in borderline ovarian tumors, revealed an accuracy of 60% with an agreement between final pathology and frozen section results. Overall, 24.5% of under-diagnosed malignant cases interpreted to be benign and 4.9% overdiagnosed cases with benign tumor considered as a malignant. Frozen section is a reliable tool to exclude benign tumor from borderline and malignant but underdiagnosed percentage is higher. There are limitations in this review including the small number of enrolled cases, different time of diagnosis and different investigated countries and the discrepancies between the studied articles in this review.

Crystallization of Trehalose in Frozen Solutions and its Phase Behavior during Drying

To study the crystallization of trehalose in frozen solutions and to understand the phase transitions during the entire freeze-drying cycle. Aqueous trehalose solution was cooled to -40 C in a custom-designed sample holder. The frozen solution was warmed to -18 C and annealed, and then dried in the sample chamber of the diffractometer. XRD patterns were continuously collected during cooling, annealing and drying. After cooling, hexagonal ice was the only crystalline phase observed. However, upon annealing, crystallization of trehalose dihydrate was evident. Seeding the frozen solution accelerated the solute crystallization. Thus, phase separation of the lyoprotectant was observed in frozen solutions. During drying, dehydration of trehalose dihydrate yielded a substantially amorphous anhydrous trehalose. Crystallization of trehalose, as trehalose dihydrate, was observed in frozen solutions. The dehydration of the crystalline trehalose dihydrate to substantially amorphous anhydrate occurred during drying. Therefore, analyzing the final lyophile will not reveal crystallization of the lyoprotectant during freeze-drying. The lyoprotectant crystallization can only become evident by continuous monitoring of the system during the entire freeze-drying cycle. In light of the phase separation of trehalose in frozen solutions, its ability to serve as a lyoprotectant warrants further investigation.

This paper presents an empirical model for classifying frozen/unfrozen soils in the entire Bras d Henri River watershed (167 km 2 ) near Quebec City (Quebec, Canada). It was developed to produce frozen soil maps under snow cover using RADARSAT-1 fine mode images and in situ data during three winters. Twelve RADARSAT-1 images were analyzed from fall 2003 to spring 2006 to discern the intra- and inter annual variability of frozen soil characteristics. Regression models were developed for each soil group (parent material-drainage-soil type) and land cover to establish a threshold for frozen soil from the backscattering coefficients (HH polarization). Tilled fields showed higher backscattering signal (+3 db) than the untilled fields. The overall classification accuracy was 87% for frozen soils and 94% for unfrozen soils. With respect to land use, that is, tilled versus untilled fields, an overall accuracy of 89% was obtained for the tilled fields and 92% for the untilled fields. Results show that this new mapping approach using RADARSAT-1 images can provide estimates of surface soil status (frozen/unfrozen) at the watershed scale in agricultural areas.

Reduction in working hours, streamlined training schemes and increasing use of endovascular techniques has meant a reduction in operative experience for newer vascular surgical trainees, especially those exposures which are not routinely performed such as thoracoabdominal, thoracotomy and retroperitoneal aortic, for example. This paper describes an Advanced Anatomy of Exposure course which was designed and convened at the Clinical Training & Evaluation Centre in Western Australia and uses fresh frozen cadavers. Feedback was obtained from the participants who attended over three courses by questionnaire. Feedback was strongly positive for the course meeting both its learning outcomes and personal learning objectives, and in addition, making a significant contribution to specialty skills. Most participants thought the fresh frozen cadaveric model significantly improved the learning objectives for training. The fresh frozen cadaver is an excellent teaching model highly representative of the living open surgical scenario where advanced trainees and newly qualified consultants can improve their operative confidence and consequently patient safety in vascular surgery. An efficient fresh frozen cadaver teaching programme can benefit many health professionals simultaneously maximizing the use of donated human tissue. © 2013 Royal Australasian College of Surgeons.

Objective To determine whether frozen shoulder heals equally well in patients with and without diabetes and whether dependency on insulin affects the outcome. Methods We retrospectively examined 178 patients with idiopathic frozen shoulder; 27 patients had diabetes. We evaluated range of motion, pain, and functional results. The mean follow-up was 9.7 years (SD, 7.1 years). Results In the presence of frozen shoulder, range of motion did not differ between patients with and without diabetes. At follow-up, range of motion in all directions of both the affected and unaffected shoulders of patients with diabetes was inferior to that of patients without diabetes. Among patients with diabetes, range of motion of the once-frozen shoulder reached the level of the unaffected shoulder. Patients with and without diabetes experienced similar pain except during exertion. The Constant–Murley score was not significantly different between the two groups, and insulin dependency did not lead to worse outcomes. Conclusion Frozen shoulder heals well in patients with diabetes. PMID:27856934

Acute invasive fungal rhinosinusitis (AIFRS) represents a fulminant, potentially fatal, disease process in immunocompromised patients. The diagnosis often rests on high index of clinical suspicion, with relative paucity of data on the diagnostic and therapeutic implications of intraoperative frozen sections. Retrospective review was performed for 18 cases undergoing endoscopic sinus surgery for AIFRS. Reliability of intraoperative frozen section diagnosis was evaluated for all patients using final pathology as the gold standard. A total of 66 frozen sections were performed. Diagnostic accuracy of frozen sections illustrated sensitivity of 72.7% (95% confidence interval [CI], 0.57 to 0.85), specificity of 100% (95% CI, 0.85 to 1.00), positive predictive value (PPV) of 100% (95% CI, 0.89 to 1.00), and negative predictive value (NPV) of 64.7% (95% CI, 0.46 to 0.80). There was no statistically significant difference in sensitivity of frozen sections in cases of Mucor and Aspergillus at 68.8%% and 76.2%, respectively (p = 0.61). This study represents the largest series assessing the diagnostic accuracy of frozen section analysis in AIFRS. Frozen section analysis is an effective tool for guiding intraoperative decision making in patients with AIFRS with a high PPV. A Low NPV underscores the importance of clinical suspicion and intraoperative decision making based on endoscopic findings when negative frozen section results are encountered. Further, frozen section analysis appears to be equally effective in detecting either Mucor or Aspergillus. © 2017 ARS-AAOA, LLC.

Frozen ground degradation resulting from climate warming on the Tibetan Plateau has aroused wide concern in recent years. In this study, the maximum thickness of seasonally frozen ground (MTSFG) is estimated by the Stefan equation, which is validated using long-term frozen depth observations. The permafrost distribution is estimated by the temperature at the top of permafrost (TTOP) model, which is validated using borehole observations. The two models are applied to the upper Yellow River Basin (UYRB) for analyzing the spatio-temporal changes in frozen ground. The simulated results show that the areal mean MTSFG in the UYRB decreased by 3.47 cm/10 a during 1965-2014, and that approximately 23% of the permafrost in the UYRB degraded to seasonally frozen ground during the past 50 years. Using the climate data simulated by 5 General Circulation Models (GCMs) under the Representative Concentration Pathway (RCP) 4.5, the areal mean MTSFG is projected to decrease by 1.69 to 3.07 cm/10 a during 2015-2050, and approximately 40% of the permafrost in 1991-2010 is projected to degrade into seasonally frozen ground in 2031-2050. This study provides a framework to estimate the long-term changes in frozen ground based on a combination of multi-source observations at the basin scale, and this framework can be applied to other areas of the Tibetan Plateau. The estimates of frozen ground changes could provide a scientific basis for water resource management and ecological protection under the projected future climate changes in headwater regions on the Tibetan Plateau.

Disinfected water and/or disinfectants are commonly used by the freezing industry in such processes as sanitising, washing, blanching, cooling and transporting the final product. For this reason, disinfection by-products (DBPs) can be expected in frozen foods. This study focused on the presence of DBPs in a wide variety of frozen vegetables, meats and fish. For this purpose, the 14 halogenated DBPs more prevalent in disinfected water were selected (four trihalomethanes, seven haloacetic acids, two haloacetonitriles and trichloronitromethane). Up to seven DBPs were found in vegetables, whereas only four DBPs were present in meats and fish, and at lower concentrations, since their contact with disinfected water is lower than in frozen vegetables. It is important to emphasise that trichloronitromethane (the most abundant nitrogenous DBP in disinfected water) was found for the first time in foods. Finally, it was concluded that the freezing process can keep the compounds stable longer than other preservation processes (viz. sanitising, canning) and, therefore, frozen foods present higher DBP concentrations than other food categories (minimally processed vegetables, or canned vegetables and meats).

Freezing of herring (Clupea harengus) for human consumption is increasing in the Nordic herring industry, either onboard the fishing vessels or right after landing. The quality of frozen herring as a raw material does not only depend on the frozen storage conditions applied, but also...... on compositional features, something which in turn can vary with season and catching ground. To unravel the link between biological variations, basic muscle composition, and sensory properties of frozen herring, a unique herring raw material was caught by commercial fishing vessels at three locations: around...... the utilization of herring for frozen storage for human consumption....

This paper presents a new precooling method which reduces the temperature of mixed concrete by mixing it with sand frozen by liquid nitrogen. The authors tried to clarify the properties of both the frozen sand and the concrete mixed with the frozen sand. The results of a series of experimental studies indicate that the temperature of mixed concrete can be reduced about 25degC, which is a larger reduction quantity than that achieved by conventional precooling methods; and that this method contributes to improvement of the consistency and the compressive strength of the concrete. Furthermore, the advantageous effect of this precooling method is confirmed from the results of laboratory tests using massive concrete members. (author)

1989-04-01

For γN→ΠN and γd→pn scattering experiments at the PHOENICS detector, a new 'bonn frozen spin target' (BOFROST) is developed. The target with a maximum volume of 30 cm 3 is cooled in a vertical 3 He- 4 He dilution kryostat. The lowest temperature of the dilution kryostat in the frozen spin mode should be 50 mk. In a first stage, the magnet system consist of two superconducting solenoids: A polarisation magnet with a maximum field of 7 T with a homogenity of 10 -5 over the target area and a 'vertical holding' magnet with a maximum field in the target area of 0.57 T. This work describes the construction and the set-up of the 'frozen spin target' in the laboratory and the first tests of the dilution kryostat and the superconducting magnet system. (orig.) [de

Full Text Available Calcific tendinitis of the shoulder is a process that involves calcium deposition in the rotator cuff tendons. It is usually a self-limiting process and is often chronic in nature. However, it can lead to acute pain resulting in frozen shoulder syndrome. We report 32 cases in which frozen shoulder was associated with calcific tendinitis of the supraspinatus. The aim of this study was to use arthroscopic brisement of the glenohumeral joint and make multiple punctures in the calcific spot to treat the frozen shoulder associated with calcific tendinitis of the supraspinatus. In our study, 30 patients had satisfactory results after a 2-year follow-up. Five patients experienced some postoperative calcium shadows, but there was also greater improvement in the range of motion and pain relief in this study compared with other reports in the literature of frozen shoulder cases.

This document describes the various styles which are recommended for Starlink documents. It also explains how to use the templates which are provided by Starlink to help authors create documents in a standard style. This paper is concerned mainly with conveying the ``look and feel" of the various styles of Starlink document rather than describing the technical details of how to produce them. Other Starlink papers give recommendations for the detailed aspects of document production, design, layout, and typography. The only style that is likely to be used by most Starlink authors is the Standard style.

The home environment is likely to influence children's diet and activity patterns and ultimately, their weight trajectories. Identifying family characteristics associated with a more 'obesogenic' home can provide insight into the determinants, and has implications for targeting and tailoring strategies to promote healthier lifestyles. The present study examined maternal characteristics associated with a more obesogenic home environment in 1113 families with preschool children. Primary caregivers (99% mothers) from the Gemini cohort completed the Home Environment Interview (HEI) when their children were 4 years old. Maternal demographics and BMI were assessed in the Gemini baseline questionnaire when the children were on average 8 months old. Maternal eating style was assessed when the children were on average 2 years old, using the Dutch Eating Behaviour Questionnaire (DEBQ). Responses to the HEI were standardised and summed to create a composite score of the obesogenic quality of the home; this was categorised into tertiles. Multivariate ordinal logistic regression showed that mothers who were younger (adjusted OR; 95% CI = 0.96; 0.94-0.98), less educated (1.97; 1.40-2.77), and had lower incomes (1.89; 1.43-2.49) at baseline were more likely to live in an obesogenic home environment at 4 years, as were mothers who scored higher on the DEBQ External Eating scale (1.40; 1.16-1.70) at 2 years, and had a higher baseline BMI (1.05; 1.02-1.08). Using a novel, composite measure of the home environment, this study finds that families who are more socio-economically deprived, and where the mothers are themselves heavier and have a more food responsive eating style, tend to provide a home environment with the hallmarks of a higher risk of weight gain.

Detection method of prawn irradiated in frozen state using tyrosine isomers as a marker

International Nuclear Information System (INIS)

Oikawa, H.; Satomi, M.; Omura, Y.; Yano, Y.

2001-01-01

Internationally the use of food irradiation has been expanding. And therefore a method is needed to detect whether food has been irradiated or not. We examined the content of the tyrosine isomers, m-tyrosine and omicron-tyrosine, of prawns irradiated in the frozen state (< -30 deg C) as a marker of the detection method. The tyrosine isomer content linearly increased with increasing dose, and the level of tyrosine isomers in the frozen-irradiated prawn was 50 - 60 % of the un frozen ones. But the difference in the content of tyrosine isomers between non-irradiated and irradiated at 5.0 kGy, that is the approved dose for frozen shellfish in countries where this technique is approved, is enough for discrimination. In addition, the content of tyrosine isomers showed little change during the frozen storage for 120 days. So we think the method using tyrosine isomers is suitable for practical use in Japan for imports of many kinds of frozen shellfish

Frozen shoulder is a potential complication after shoulder surgery. It is a clinical condition that is often associated with marked disability and can have a profound effect on the patient's quality of life. The incidence, etiology, pathology and prognostic factors of postoperative frozen shoulder after shoulder surgery are not known. The purpose of this explorative study was to determine the incidence of postoperative frozen shoulder after various operative shoulder procedures. A second aim was to identify prognostic factors for postoperative frozen shoulder after shoulder surgery. 505 consecutive patients undergoing elective shoulder surgery were included in this prospective cohort study. Follow-up was 6 months after surgery. A prediction model was developed to identify prognostic factors for postoperative frozen shoulder after shoulder surgery using the TRIPOD guidelines. We nominated five potential predictors: gender, diabetes mellitus, type of physiotherapy, arthroscopic surgery and DASH score. Frozen shoulder was identified in 11% of the patients after shoulder surgery and was more common in females (15%) than in males (8%). Frozen shoulder was encountered after all types of operative procedures. A prediction model based on four variables (diabetes mellitus, specialized shoulder physiotherapy, arthroscopic surgery and DASH score) discriminated reasonably well with an AUC of 0.712. Postoperative frozen shoulder is a serious complication after shoulder surgery, with an incidence of 11%. Four prognostic factors were identified for postoperative frozen shoulder: diabetes mellitus, arthroscopic surgery, specialized shoulder physiotherapy and DASH score. The combination of these four variables provided a prediction rule for postoperative frozen shoulder with reasonable fit. Level II, prospective cohort study.

Frozen reaction fronts in steady flows: A burning-invariant-manifold perspective

Mahoney, John R.; Li, John; Boyer, Carleen; Solomon, Tom; Mitchell, Kevin A.

2015-12-01

The dynamics of fronts, such as chemical reaction fronts, propagating in two-dimensional fluid flows can be remarkably rich and varied. For time-invariant flows, the front dynamics may simplify, settling in to a steady state in which the reacted domain is static, and the front appears "frozen." Our central result is that these frozen fronts in the two-dimensional fluid are composed of segments of burning invariant manifolds, invariant manifolds of front-element dynamics in x y θ space, where θ is the front orientation. Burning invariant manifolds (BIMs) have been identified previously as important local barriers to front propagation in fluid flows. The relevance of BIMs for frozen fronts rests in their ability, under appropriate conditions, to form global barriers, separating reacted domains from nonreacted domains for all time. The second main result of this paper is an understanding of bifurcations that lead from a nonfrozen state to a frozen state, as well as bifurcations that change the topological structure of the frozen front. Although the primary results of this study apply to general fluid flows, our analysis focuses on a chain of vortices in a channel flow with an imposed wind. For this system, we present both experimental and numerical studies that support the theoretical analysis developed here.

Diagnosis of fruit sensitisation by skin prick test (SPT) is fast and easy to perform. Nevertheless, some fruit is not available throughout the year. Freezing aliquots of these fresh fruits to be defrosted would be a good solution to perform SPT at any time. To compare the reproducibility of SPT with Rosaceae and Cucurbitaceae frozen fruit with fresh and commercial fruit extracts. SPT with the following fruit were performed: apricot, cherry, strawberry, nectarine, Japanese medlar, peach, (peel and pulp), yellow and red plum, melon and watermelon. We compared fresh fruit, commercial extract and fruit which had been frozen at -18 degrees C. Results were read by planimetry (Inmunotek prick-film) after 15 minutes. The study group comprised 48 patients (9 males, 39 females) with a mean age of 31, 6 +/- 2.0 years. Concordance of positive and negative results was extremely high and significant in all cases. Correlation between frozen fruit and commercial extract, frozen fruit and fresh and commercial extract and fresh fruit was statistically significant in all cases except for strawberry. The use of frozen fruit is a valid method, as the performance of the SPT is similar to that of fresh fruit. This enables diagnostic procedures with seasonal fruit at any time of the year.

A frozen spin polarized target, constructed at Jefferson Lab for use inside a large acceptance spectrometer, is described. The target has been utilized for photoproduction measurements with polarized tagged photons of both longitudinal and circular polarization. Protons in TEMPO-doped butanol were dynamically polarized to approximately 90% outside the spectrometer at 5 T and 200-300 mK. Photoproduction data were acquired with the target inside the spectrometer at a frozen-spin temperature of approximately 30 mK with the polarization maintained by a thin, superconducting coil installed inside the target cryostat. A 0.56 T solenoid was used for longitudinal target polarization and a 0.50 T dipole for transverse polarization. Spin relaxation times as high as 4000 hours were observed. We also report polarization results for deuterated propanediol doped with the trityl radical OX063.

Analytical procedures for bulk frozen-hydrated biological tissues

The main advantage of using solid frozen samples for elemental x-ray microanalysis is the ease with which they may be prepared and maintained in the frozen-hydrated state. Within the limits imposed by the reduced spatial resolution of the method, the morphological identification of the tissue components is comparatively easy. Bearing in mind these limitations, the authors have carried out an analysis for several elements in the developing root tips of Lemna minor L (Duckweed). Fresh root tips of Lemna minor L, briefly encapsulated in a polymeric cryoprotectant, are quench frozen in melting nitrogen at ca. 70 0 K and transferred to the pre-cooled cold stage of an AMray Biochamber. The analysis was carried out by means of a Kevex energy-dispersive detector by use of the peak-to-background ratio method. These procedures allow the authors to obtain flat fracture faces in which they have been able to measure the relative concentrations of various elements at the various stages of differentiation in the root tissue

2015-02-01

Branchial cleft cysts occur because of a failure of involution of the second branchial cleft. However, as well-differentiated squamous cell carcinoma can mimic branchial cleft cysts, there is a lack of consensus on the appropriate management of cystic neck lumps. To report our experience of fine needle aspiration cytology and frozen section examination in the management of cystic neck lumps. Retrospective case note review of patients managed in the Southern General Hospital, Scotland, UK. The sensitivity of fine needle aspiration cytology and frozen section for detecting branchial cleft cysts was 75 per cent and 100 per cent respectively. Two patients who did not undergo intra-operative frozen section examination were either over- or under-treated, which is discussed. Adult patients subjected to surgical excision of a suspected branchial cyst should undergo intra-operative frozen section analysis regardless of clinical suspicion for malignancy. This part of management is critical to ensure patients are offered appropriate treatment.

Reactions of recoil 38 Cl, 80 Br and 128 I have been studied in crystalline systems of 5-halouracil, 5-halo-2'-deoxyuridine and 5-halouridine as well as liquid and frozen aqueous solutions of these halogenated biomolecules. In all systems expect crystalline 5-iuodouracil the major product was the radio-labelled halide ion. There was no evidence for other halogen inorganic species. The major labelled organic product was the parent molecule. A recoil atom tracer technique was developed to acquire site information of the biomolecule solutes in the liquid and frozen aqueous systems. For all liquid and frozen aqueous systems, the halogenated biomolecules tended to aggregate. For liquid systems, the tendency for aggregation diminished as the solute concentration approached zero, where the probable state of the solute approached a monomolecular dispersion. Unlike the liquid state, the frozen ice lattice demonstated a ''caging effect'' for the solute aggregates which resulted in constant product yields over the whole concentration range. (orig.)

Full Text Available : Chilled and frozen chicken breast and thigh meat were stored at +4±1 oC and - 20±1 oC, respectively. Maillard reaction between ribose and meat proteins of the chicken samples was initiated. The changes in the ribose-induced Maillard reaction rate during chilled and frozen storage of chicken meat were evaluated on the bases of corrected absorbance values (A420* and bovine melanoidin equivalent values (mg BME/g. Application of BME as a measure of ribose-induced Maillard reaction rate enables comparability of the data obtained by different spectrophotometers. It was found that the BME values of chicken meat frozen stored for more than 15 days were significantly (P<0.05 lower than BME values of chilled-stored samples. According to the suggested threshold limit values the chicken thigh and breast meat with BME values lower than 30 mg BME/g and 51 mg BME/g, respectively could be classified as frozen-thawed.

Intraoperative consultation plays an important role in the management of soft tissue sarcomas, such as rhabdomyosarcoma. In this study, we aimed to draw attention to the important points during frozen section interpretation, and analyse the accuracy of frozen diagnosis in rhabdomyosarcoma patients. The cases, both diagnosed as rhabdomyosarcoma or followed with a history of rhabdomyosarcoma, and interpreted with intraoperative consultation (frozen section) between 2000 and 2013 were culled from pathology archives. The diagnoses were confirmed by desmin and myogenin, immunohistochemically. The frozen and final diagnoses were noted of 21 biopsy specimens of 19 patients. Sensitivity and specificity of intraoperative consultation were calculated regarding to the major diagnostic discrepancies leading to a change in surgical management of the patient, after exclusion of the cases deferred to paraffin section. Of the evaluated 21 biopsy material, 3 (14%) were misdiagnosed: Of the 2 false negative embryonal rhabdomyosarcoma cases, sample was not representative of the tumor, and there was chemo/radiotherapy induced changes in the other case. In the only false positively diagnosed case with a known history of rhabdomyosarcoma, inflammatory cells were misinterpreted as small round cell neoplasm. In 5 (29%) of 21 biopsies, a frozen diagnosis could not be given, and the diagnosis was deferred. Six cases (29%) were evaluated with cytological squash or imprint preparation; none of the misdiagnosed cases was evaluated with adjunct cytological preparation. Six of 8 misdiagnosed or deferred biopsies showed morphological changes secondary to radiotherapy and/or chemotherapy. Sensitivity, specificity, positive predictive value, and negative predictive value were calculated as 85%, 67%, 92% and 50%, respectively. Intraoperative consultation for rhabdomyosarcoma is a reliable tool with high sensitivity and fair specificity. Cases with treatment effect may lead to diagnostic difficulties

The distribution of cryoprotectant (10% glycerol) and ice along the frozen plastic straw (the most useful container for freezing mammalian semen, oocytes and embryos) was studied by Raman scattering technique. Raman spectroscopy being a contactless, non-invasive tool was applied for the straws filled with the cryoprotectant solution and frozen by controlled rate programs commonly used for mammalian embryos freezing. Analysis of Raman spectra measured at different points along the straw reveals a non-uniform distribution of the cryoprotectant. The ratio between non-crystalline solution and ice was found to be increased by several times at the bottom side of the solution column frozen by the standard freezing program. The increase of the cryoprotectant fraction occurs in the area where embryos or oocytes are normally placed during their freezing. Possible effects of the cooling rate and the ice nucleation temperature on the cryoprotectant fraction at the bottom side of the solution column were considered. Our findings highlight that the ice fraction around cryopreserved embryos or oocytes can differ significantly from the averaged one in the frozen plastic straws. Copyright © 2016 Elsevier Inc.

Style over substance: What can parenting styles tell us about ownership styles and obesity in companion animals?

Science.gov (United States)

German, Alexander J

2015-01-01

Obesity is a major medical concern in human subjects, and most concerning is the rapid recent increase in childhood obesity. Children are more likely to be obese if their parents are obese, an effect that is mediated both by genetics and environment, most notably parental influence. Four major parenting styles have been recognised: authoritative; authoritarian; indulgent; uninvolved. Too much parental control, as with the authoritarian style, is associated with a higher weight status in children. Conversely, indulgent feeding styles can also have negative consequences and, where control is too lax, a poor relationship with food develops, which may also lead to weight gain. Obesity is also a growing concern in companion animals, and it has parallels with obesity in children. For instance, overweight people are more likely to own overweight dogs. Furthermore, the care that people provide for their pets mirrors that which parents provide for children, and pets are commonly viewed as child substitutes. These similarities raise obvious questions about whether different styles of pet ownership exist, and what part they may play in attitudes to feeding as well as predisposition to obesity in pets. Future work could focus on determining to what extent styles of pet ownership mirror parenting styles, whether there are links to obesity in dogs and cats. Knowledge regarding the owner-pet bond might provide comparative insights into the links between parenting styles and childhood obesity.

Experiential learning theory (ELT), a theory developed by David Kolb that considers experience to be very important for learning, classifies learners into four categories: Divergers, Assimilators, Convergers, and Accommodators. Kolb used his Learning Style Inventory (LSI) to validate ELT. Knowing the learning styles of students facilitates their understanding of themselves and thereby increases teaching efficiency. Few studies have been conducted that investigate learning preferences of students in the field of dentistry. This study was designed to distinguish learning styles among Saudi dental students and interns utilizing Kolb's LSI. The survey had a response rate of 62 percent (424 of 685 dental students), but surveys with incomplete answers or errors were excluded, resulting in 291 usable surveys (42 percent of the student population). The independent variables of this study were gender, clinical experience level, academic achievement as measured by grade point average (GPA), and specialty interest. The Diverging learning style was the dominant style among those in the sample. While the students preferred the Assimilating style during their early preclinical years, they preferred the Diverging style during their later clinical years. No associations were found between students' learning style and their gender, GPA, or specialty interest. Further research is needed to support these findings and demonstrate the impact of learning styles on dental students' learning.

Full Text Available The aim of study is to confirm a new technique that can crush the frozen soil and/or ice block using underwater shock wave generated by the underwater explosion of explosive. This technique can lead to the earlier sowing, which can have the larger harvest because the duration of sunshine increases. Especially, in Hokkaido prefecture, Japan, if the sowing is carried out in April, we can expect to have 150% of harvest in the ordinary season. In the case of small processing area such as road repairing, frozen soil is thawed by using the heat of gas burner and/or the electric heater. It is not a suitable plan to apply these heating methods to agriculture, from the point of view enormous amount of processing area. Thawing technique for frozen soil is effective against the cold regions, for example, Russia, Norway, and Sweden, etc. At first, we carried out experiments using a detonating fuse and ice block. The propagation process of shock wave into the ice block was observed by means of a high-speed camera. In order to check about that influence we tried to give an actual frozen soil a shock wave. We could get a result that existence of water layer serves an important role in promotion of thawing by the shock loading to the frozen soil.

Lactobacillus bulgaricus cells were entrapped in beads of calcium alginate and evaluated for their ability to survive freezing processes. Cells survived freezing (without agitation) in ice milk mix much better than in distilled water, and more entrapped cells survived than did cells that were not entrapped. Glycerol and mannitol were cryoprotective, but glucose was not, when each was added (6%) separately to the beads. Entrapment protected the lactobacilli in batch frozen and continuously frozen ice milk mixes. The percentage of survival for entrapped and unentrapped cells in continuously frozen ice milk approximated 90 and 40%, respectively. Lactobacilli survived better in beads with mean diameters > 30 microns than in those averaging 15 microns. Addition of entrapped lactobacilli had no measurable effect on the sensory characteristics of the ice milk.

Bacteriological surveillance is little applied in management of equine frozen semen but it is quite important to verify the microbial contamination in order to find out the chance of transmission of pathology to the mare in AI. Authors describe a qualitative and quantitative analysis for bacterial contamination on long time (3-17 years) equine frozen semen stored in liquid nitrogen. The semen checked, produced in Italy and in another Europe country, was cryopreserved in liquid nitrogen inside sealed plastic straws. One hundred and ten straws were checked out for pathogenic and no pathogenic bacteria, aerobes and anaerobes and fungi (moulds and yeasts). The Total Microbial Charge was quite variable with an average of about 1.4 x 10(5)CFU/ml. Mostly the microbial agents identified were fungi (17.5%), Enterobacter-coccus spp. (15%), Pseudomonas spp. (6.25%), Stenothophomonas maltophila (6.25%) and anaerobic bacteria like Propionibacterium granulosum (7.5%) and Clostridium spp. (3.75%). 3.75% were unidentified Gram-negative rod and cocci. Streptococcus spp., Staph. aureus, E. coli, Th. equigenitalis and Mycoplasma spp. were not detected. The most represented species were Enterobacter-coccus spp. (1.1 x 10(5)CFU/ml), St. maltophila (8 x 10(4)CFU/ml) and Pr. granulosum (7 x 10(4)CFU/ml) while yeast and even more moulds were little abundant (4.7 x 10(4) and 3.4 x 10(4)CFU/ml respectively). The knowledge of equine frozen semen microbial quality is essential to check out transmission of venereal disease and improve the quality of cryopreserved germplasm.

1996-01-01

Phosphate buffer suspensions of three strains of Escherichia coli were irradiated with gamma-rays at room temperature and deep frozen conditions. They were inoculated on MacConkey agar plates to see the comparative sensitivities to the irradiation. Compared to the irradiation at room temperature, the sensitivities of the strains decreased by irradiation at deep frozen conditions. Addition of glycerol to the E. coli suspensions decreased the sensitivities of E. coli to gamma-rays not only at room temperature but also at deep frozen conditions. These phenomena were elucidated by the decrease of production and mobility of OH radicals at deep frozen conditions. (author)

Styles and Style-Stretching: How are They Related to Successful Learning?

Griffiths, Carol; İnceçay, Görsev

2016-06-01

Although the learning style construct has aroused much interest over the years, questions remain regarding basic issues such as definition, the validity and/or reliability of various measurement instruments, and the relationship between learning style and successful learning. Furthermore, although maintaining stylistic flexibility is recommended by many authors, few studies have attempted to relate the style-stretching concept to successful learning. This study therefore attempted to address these questions. According to results, conducted among 106 Turkish university students, using an original instrument constructed using elements from established questionnaires, a small group of styles was significantly correlated with exam results, accounting for about a quarter of the variance (considered a large effect size in social science). In addition, higher-scoring students reported a more eclectic range of styles, suggesting more willingness to style-stretch, while lower-scoring students reported a more limited range. Pedagogical implications as well as areas for ongoing research are suggested.

The main aim of this study was to explore the associations between appraised leadership styles, psychosocial work factors and musculoskeletal pain among subordinates in four different public service sectors from an epidemiological perspective. A cross-sectional questionnaire study was conducted; data from 2,403 public sector employees in subordinate positions (86% women) were analysed. The appraised leadership styles were measured through items from a modified version of the CPE questionnaire (C change, P production/structure, E employee/relation). The structure validity of the CPE-model was examined by principal component analysis (PCA). Univariate and multivariate analyses of associations between levels of musculoskeletal pain and appraised leadership styles and with psychosocial work factors were conducted. Odds ratios (ORs) with confidence intervals (CIs) of 95% were used as a measure of associations. There were small variations in the appraisals of the immediate manager among the subordinates. However, the associations between musculoskeletal pain and leadership styles varied according to sector. Poor appraisals (low scores) on "change" and "employee relation" dimensions were associated with high levels of musculoskeletal pain in two sectors: home and health care services. In the domestic catering services, poor appraisals of managers in the "production/structure" dimension had the strongest association with high levels of pain. In general, poor appraisals of the "change" dimension was most strongly associated with high levels of musculoskeletal pain. "High work demands" had the strongest association with high levels of pain, particularly among the men. Poor appraisals of managers and their leadership styles were associated with high levels of musculoskeletal pain among both female and male subordinates in different public service sectors. There is therefore a great need of further studies of the mechanisms behind the relationships between the leadership

Research suggests an inverse association between parental rules and screen time in pre-adolescents, and that parents' style of communication with their children is related to the children's time spent watching TV. The aims of this study were to examine associations of parental rules and parental style of communication with children's screen time and perceived excessive screen time in five European countries. UP4FUN was a multi-centre, cluster randomised controlled trial with pre- and post-test measurements in each of five countries; Belgium, Germany, Greece, Hungary and Norway. Questionnaires were completed by the children at school and the parent questionnaire was brought home. Three structural equation models were tested based on measures of screen time and parental style of communication from the pre-test questionnaires. Of the 152 schools invited, 62 (41 %) schools agreed to participate. In total 3325 children (average age 11.2 years and 51 % girls) and 3038 parents (81 % mothers) completed the pre-test questionnaire. The average TV/DVD times across the countries were between 1.5 and 1.8 h/day, while less time was used for computer/games console (0.9-1.4 h/day). The children's perceived parental style of communication was quite consistent for TV/DVD and computer/games console. The presence of rules was significantly associated with less time watching TV/DVD and use of computer/games console time. Moreover, the use of an autonomy-supportive style was negatively related to both time watching TV/DVD and use of computer/games console time. The use of a controlling style was related positively to perceived excessive time used on TV/DVD and excessive time used on computer/games console. With a few exceptions, results were similar across the five countries. This study suggests that an autonomy-supportive style of communicating rules for TV/DVD or computer/ games console use is negatively related to children's time watching TV/DVD and use of computer/games console time

This paper deals with the direct numerical simulation of quasi-stationary (frozen) wave formation at the interface of two immiscible fluids with large viscosity contrast, in a rectangular container subjected to the horizontal vibrations of finite frequency and amplitude. The critical conditions for the origination of a frozen wave as well as the dependences of the frozen wave height and wavelength on the vibration intensity are obtained. The time-evolution of the interface shape during the vibration period is analyzed. Numerical results are found to be in a good agreement with known experimental and linear stability results. The average deformation of the interface and the structure of average flows are calculated for different vibration intensities. It is shown that a change in the dependencies of the frozen wave characteristics on the vibration intensity follows a change in average flow structure. (paper)

Intelligent home is becoming the hot spot of social attention in the 21st century. When it is in China, it is a really new industry. However, there is no doubt that Intelligent home will become a new economic growth point of social development; it will change the life-style of human being. To develop the intelligent home, we should keep up with the development trend of technology. This is the reason why I talk about the intelligent home control system here. In this paper, intelligent home control system is designed for alarm and remote control on gas- leaking, fire disaster, earthquake prediction, etc., by examining environmental changes around house. When the Intelligent home control system has detected an accident occurs, the processor will communicate with the GSM module, informing the house keeper the occurrence of accident. User can receive and send the message to the system to cut the power by mobile phone. The system can get access to DCCthrough ARM10 JTAG interface, using DCC to send and receive messages. At the same time, the debugger on the host is mainly used to receive the user’s command and send it to the debug component in the target system. The data that returned from the target system is received and displayed to the user in a certain format.

The objective of this study was to investigate the quality of frozen-thawed semen from different bull breeds. Commercial frozen-thawed bull semen samples (26 per breed, 130 totally) of five breeds (Holstein [Η], Brown Swiss [BS], Limousin [L], Belgian Blue [BB], Blonde d' Aquitaine [BA]) were used. After thawing, each semen sample was subjected to thermal resistance test (TR) for 0.5 and 1 hr at 38°C and hypo-osmotic swelling test (HOST) for 1 hr at 150 mOsm at 37°C. Additionally, all samples were evaluated at times 0 hr (thawing), 0.5 hr (TR), 1 hr (TR) for kinetics by CASA [progressive, immotile, rapid, medium, slow moving spermatozoa, curvilinear velocity (VCL), average path velocity (VAP), straight line velocity (VSL), linearity (LIN), straightness (STR), beat cross-frequency (BCF), amplitude of lateral head displacement (ALH), wobble (WOB)]. Moreover, directly after thawing, all semen samples were evaluated for morphometry, morphology, viability and DNA fragmentation. Statistical analysis was conducted using a mixed model for repeated measures. The results showed (a) higher VCL after thawing in H, L breeds compared to BB and BA, (b) higher VAP after thawing in L compared to BB, BA, (c) higher values of progressive spermatozoa after TR in H, BS compared to BB, BA, (d) higher values of rapid spermatozoa after thawing and 0.5 hr of TR in H, BS, L compared to BB, BA, (e) lower viability in BA after thawing compared to H, BS, BB, (f) lower morphological abnormalities in H compared to L, BB, (g) higher head length in Η compared to BB. No significant differences were observed in the results from HOST and DNA fragmentation between breeds. In conclusion, quality characteristics of frozen-thawed bull semen are dependent on the breed. Frozen semen from BB and BA breeds should be handled more carefully after thawing, as it is more sensitive to stress. © 2016 Blackwell Verlag GmbH.

The addition of Orvus ES paste (OEP) to extender may be essential for preparing frozen dog semen. The major ingredient of OEP is sodium lauryl sulfate (SLS). In this study, we compared the effect of SLS on frozen dog semen with that of OEP. There were no significant differences between the 2-mg/ml SLS group and OEP group concerning sperm motility, viability and the percentage of viable sperm with intact acrosomes after freeze-thawing. These results suggest that the effectiveness of frozen dog semen extender containing 2 mg/ml of SLS is similar effective to that demonstrated for OEP.

To explain the role of arthroscopic release in intractable frozen shoulders. We used different questionnaires and measuring tools to understand whether arthroscopic release is the superior modality to treat patients with intractable frozen shoulders. Between 2007 and 2013, in a prospective study, we enrolled 80 patients (52 females and 28 males) with recalcitrant frozen shoulder, who underwent arthroscopic release at Ghaem Hospital, a tertiary referral center, in Mashhad, Iran. Before operation, all patients filled out the Disability of Arm, Shoulder and Hand (DASH), Constant, University of California Los Angeles (UCLA), ROWE and Visual Analogue Scale (VAS) for pain questionnaires. We measured the difference in range of motion between both the normal and the frozen shoulders in each patient. The average age of the patients was 50.8±7.1 years. In 49 patients, the right shoulder was affected and in the remaining 31 the left side was affected. Before surgery, the patients were suffering from this disease on average for 11.7±10.3 months. The average time to follow-up was 47.2±6.8 months (14 to 60 months). Diabetes mellitus (38%) and history of shoulder trauma (23%) were the most common comorbidities in our patients. We did not find any significant differences between baseline characteristics of diabetics patients with non-diabetics ones. After surgery, the average time to achieve maximum pain improvement and range of motion were 3.6±2.1 and 3.6±2 months, respectively. The VAS score, constant shoulder score, Rowe score, UCLA shoulder score, and DASH score showed significant improvement in shoulder function after surgery, and shoulder range of motion improved in all directions compared to pre-operation range of motion. According to our results, arthroscopic release of recalcitrant frozen shoulder is a valuable modality in treating this disease. This method could decrease pain and improve both subjective and objective mid-term outcomes.

Full Text Available Background: To explain the role of arthroscopic release in intractable frozen shoulders. We used different questionnaires and measuring tools to understand whether arthroscopic release is the superior modality to treat patients with intractable frozen shoulders. Methods: Between 2007 and 2013, in a prospective study, we enrolled 80 patients (52 females and 28 males with recalcitrant frozen shoulder, who underwent arthroscopic release at Ghaem Hospital, a tertiary referral center, in Mashhad, Iran. Before operation, all patients filled out the Disability of Arm, Shoulder and Hand (DASH, Constant, University of California Los Angeles (UCLA, ROWE and Visual Analogue Scale (VAS for pain questionnaires. We measured the difference in range of motion between both the normal and the frozen shoulders in each patient. Results: The average age of the patients was 50.8±7.1 years. In 49 patients, the right shoulder was affected and in the remaining 31 the left side was affected. Before surgery, the patients were suffering from this disease on average for 11.7±10.3 months.  The average time to follow-up was 47.2±6.8 months (14 to 60 months. Diabetes mellitus (38% and history of shoulder trauma (23% were the most common comorbidities in our patients. We did not find any significant differences between baseline characteristics of diabetics patients with non-diabetics ones. After surgery, the average time to achieve maximum pain improvement and range of motion were 3.6±2.1 and 3.6±2 months, respectively.

Full Text Available The main purpose of this study is to explore the relation between decision-making styles which are measured by the General decision-making style (GDMS test and information processing styles which are often termed cognitive styles and are, in this study, measured by Cognitive Style Inventory. The authors directed a survey research on 162 Iranian students. Structural equation modeling techniques were used to measure the impact of cognitive styles on decision-making styles. The authors found that cognitive styles have a positive impact on decision-making styles. In spite of the abundant research on factors that affect decision-making styles, few researches have tested the relationship between cognitive styles and decision-making styles. This study examines the impact of cognitive styles on decision-making styles in Iran. This study, like most research paper studies, cannot easily be generalized. Furthermore, the results of this study could be affected by economic conditions.

Park, Eun Young; Jang, Sung-Bum; Lim, Seung-Taik

2016-12-15

The baking quality of frozen doughs containing different levels of fructo-oligosaccharides (FO) or isomalto-oligosaccharides (IMO) (3-9%, w/w flour), and stored for 0-8weeks at -18°C, was examined. The addition of FO or IMO increased the proof volume of the dough and the loaf volume of bread prepared from frozen dough. A 6% addition of FO or IMO was optimum, giving the highest proof volume and bread loaf volume, but a higher concentration than 6% induced low baking quality including lower proof volume and bread loaf volume. The bread crumb was moister and softer after the addition of FO or IMO before, and even after, frozen storage. Darker crumb colour was observed in the bread after the addition of FO or IMO. The oligosaccharides added to the frozen dough were effective in improving the quality of bread made from frozen dough, except for resulting in a darker bread crumb. Copyright © 2016.

Organochlorine (OC) contaminants are transported to the Polar Regions, where they have the potential to bioaccumulate, presenting a threat to the health of wildlife and indigenous communities. They deposit onto snowpack during winter, and accumulate until spring, when they experience prolonged solar irradiation until snowmelt occurs. Photochemical degradation rates for aldrin and dieldrin, in frozen aqueous solution made from MilliQ water, 500 {mu}M hydrogen peroxide solution or locally-collected melted snow were measured in a field campaign near Barrow, AK, during spring-summer 2008. Significant photoprocessing of both pesticides occurs; the reactions depend on temperature, depth within the snowpack and whether the predominant phase is ice or liquid water. The effect of species present in natural snowpack is comparable to 500 {mu}M hydrogen peroxide, pointing to the potential significance of snowpack-mediated reactions. Aldrin samples frozen at near 0 deg. C were more reactive than comparable liquid samples, implying that the microenvironments experienced on frozen ice surfaces are an important consideration. - Highlights: > Photodegradation rates for aldrin and dieldrin in frozen aqueous solutions made from MilliQ water, H{sub 2}O{sub 2} or melted snow are reported. > Photoprocessing depends on temperature, depth beneath the snowpack surface and dominant phase. > Species present in natural snowpack have a photosensitizing effect comparable to 500 {mu}M H{sub 2}O{sub 2}. > Aldrin samples frozen at near 0 deg. C were more reactive than comparable liquid samples. > Collectively we find that frozen aqueous surfaces play a unique role in aldrin and dieldrin photochemistry. - A field study finds that frozen aqueous solutions of aldrin and dieldrin undergo photochemical degradation under arctic snowpack conditions. The reactions are enhanced in frozen systems and by natural snowpack constituents.

Xanthogranuloma of the sellar region diagnosed by frozen section

Full Text Available Xanthogranuloma (XG of the sellar region is uncommon and is difficult to diagnose based on intraoperative frozen sections. This study is a case presentation and review of the literature, highlighting the need to explore underlying diseases in order to guarantee an accurate patient diagnosis. Herein, we presented the case of a 43-year-old woman who was afflicted with xanthogranuloma of the sellar region; the patient had a history of headache and lengthened menstrual cycles over the 6 months prior to presentation. Endocrinology tests revealed that the patient’s levels of prolactin were high and the MRI of the patient showed a clearly defined sellar mass. As a result, the patient was considered to have prolactinoma prior to undergoing surgery. The tumor was completely removed using a transsphenoidal approach, and intraoperative frozen section revealed histology similar to xanthogranuloma. When the tumor was removed by surgical operation, the patient’s visual field defects and headache were relieved. Although intraoperative frozen section should provide some guidance with regard to the diagnosis, a pathological study is conducted to confirm the actual diagnosis.

A new frozen-spin target has been developed, that allows the detection of emitted particles in an angular acceptance of almost 4π in the laboratory frame. The central part of this new target represents a 3 He/ 4 He dilution refrigerator that is installed horizontally along the beam axis. The refrigerator includes an internal superconducting holding coil to maintain the nucleon polarization in the frozen-spin mode longitudinally to the beam. The design of the dilution refrigerator and the use of an internal holding coil enabled for the first time the measurement of a spin-dependent total cross section in combination with a polarized solid state target. This new frozen-spin target was used successfully to measure the helicity asymmetry of the total photoabsorption cross-section at the Mainz accelerator facility MAMI. This experiment has been performed in order to verify for the first time the GDH sum rule

Full Text Available An inquiry of the National Statistics Institute of Spain shows that 74% of the Spanish population with disabilities suffers some kind of limitation performing Daily Basic Activities, while 1.39 million cannot perform them at all without the assistance of specialized personnel. Digital Home Systems could mitigate disabled people’s difficulties to carry out those activities, giving the opportunity to manage home appliances through a single control. Digital Home Systems have to provide specific and adapted control interfaces based on Augmentative and Alternative Communication languages in order to be an efficient solution to the problem and to allow most vulnerable groups of people with disabilities to reach the highest level of autonomy.  This paper describes a Digital Home Interface capable of adapting layouts, styles and contents to device capability, user preferences and appliances’ features; designed with a combination of web technologies, standard languages for abstract interface definition and AAC systems.

Privacy, modesty, hospitality, and the design of Muslim homes: A literature review

Directory of Open Access Journals (Sweden)

Zulkeplee Othman

2015-03-01

Full Text Available Traditional Islamic teachings and traditions involve guidelines that have direct applications in the domestic sphere. The principles of privacy, modesty, and hospitality are central to these guidelines; each principle has a significant effect on the design of Muslim homes, as well as on the organization of space and domestic behaviors within each home. This paper reviews literature on the privacy, modesty, and hospitality within Muslim homes. Nineteen publications from 1986 to 2013 were selected and analyzed for content related to the meaning of privacy, modesty, and hospitality in Islam and the design of Muslim homes. Despite the commonly shared guidelines for observing privacy, modesty, and hospitality within each home, Muslims living in different countries are influenced by cultural factors that operate within their country of residence. These factors help to shape the architectural styles and use of space within Muslim homes in different ways. Awareness of the multifactorial nature of the influences on the Muslim perception of home and the use of space is necessary for architects, building designers, engineers, and builders to be properly equipped to meet the needs of clients.

Frozen shoulder : long-term outcome following arthrographic distension.

Clement, Rhys G E; Ray, Andrew G; Davidson, Colin; Robinson, C Mike; Perks, Fergus J

2013-08-01

Arthrographic distension of the glenohumeral joint was adopted as a mainstream treatment for frozen shoulder before any randomised controlled trials were performed. Interpretation of the effectiveness of this procedure rests mostly on data from cohort studies of which there are few of high quality. Papers reporting long-term results have either excluded diabetic patients or failed to report patient orientated outcomes. The authors present a long-term prospective cohort study of 51 patients (12 diabetics and 39 non-diabetics), with 53 frozen shoulders, who had an arthrographic distension performed by a single radiologist as a primary intervention. Oxford shoulder score (OSS), visual analogue pain score (VAS), and range of movement (ROM) were recorded pre-distension, at 2 days and 1 month post-distension. OSS and VAS were recorded again at a mean of 14 months post distension (range : 8-26 months). OSS improved from a pre-distension mean of 22.3 by 16.9 points at final follow-up (p diabetic patients was the same as in non-diabetic patients. Arthrographic distension is a safe and effective treatment for frozen shoulder; it is also effective in diabetic patients. It gives long-term improvement. The authors believe that the low number of patients requiring a secondary procedure makes arthrographic distension preferable to manipulation under anaesthesia.

Baking quality of frozen dough is negatively affected by dough weakening and by a reduction in both yeast viability and activity during freezing and frozen storage. The objective of this study was to investigate effects of different enzymes, such as α-amylase, xylanase, celluase, glucose oxidase, and lipase on the texture and sensory quality of bread after frozen storage, as well as on dough properties, in terms of fermentation characteristics, freezable water contents and microstructure. Except for α-amylase, other enzymes improved the bread sensory quality and got higher overall acceptability, especially xylanase. Dough fermentative behavior showed that the maximum heights of frozen dough were increased by 33.2, 19.7 and 7.4%, respectively with xylanase, cellulase and lipase. Cellulase lowered gas holding ability of dough. Thermodynamic properties indicated that addition of enzyme decreased the freezable water contents in frozen dough. Scanning electronic microscopy revealed that freezing and frozen storage disrupted dough gluten network causing separation of starch granules from the gluten matrix. Inclusion of cellulase, xylanase and lipase made the frozen dough having a more continuous gluten network and smoother surface, and glucose oxidase increased the stability of the gluten work.

Identity style and coping strategies.

Science.gov (United States)

Berzonsky, M D

1992-12-01

This study examined the relationship between identity style and strategies used to cope with stressors that potentially threaten one's sense of identity. Identity style refers to differences in the way individuals construct and revise or maintain their sense of identity. An informational style involves actively seeking out, evaluating, and utilizing self-relevant information. A normative style highlights the expectations and standards of significant others. A diffuse/avoidant style is characterized by procrastination and situation-specific reactions. Late-adolescent college subjects were administered measures of identity style, ways of coping with academic stressors, and test anxiety. Within this self-as-student context, subjects with diffuse and normative identity styles employed avoidant-oriented coping strategies (wishful thinking, distancing, and tension reduction). An informational style was associated with deliberate, problem-focused coping. Findings are discussed in terms of a process model of identity development.

This article uses the concept of style to rethink sustainable entrepreneurship. Our point of departure is the conceptual distinction between organization as style made durable and entrepreneurship as the disruption of style. We show that style is not simply an aesthetic category, but rather what...... enable the creation of new styles. In order to conceptualize this creative process, we explore how play can create disharmonies within the organization, but we also maintain that any new practice will remain marginal without a collective assemblage capable of adopting it. On this basis, we argue...... that sustainable entrepreneurship consists of making an environmentally friendly and socially conscious style durable, but also of disrupting such a style. In order to illustrate our argument, we use the example of the sustainable smartphone producer Fairphone. In conclusion, we argue that the concept of style may...

Fink, U.; Sill, G. T.

1982-01-01

Since Whipple's dirty snowball model of comet nuclei, it has been generally accepted that volatile ices help to explain cometary phenomena. The infrared spectral properties of many substances that are potential candidates for frozen volatiles in the solar system are being pursued; indeed some of these frozen materials have been found in the solar system: H2O, CO2, and SO2. A review of laboratory spectra in the range 1 to 20 microns of H2O, CO2, SO2, CH4, NH3, H2S, CO, NH4HS and NH3.H2O is presented. Both reflection spectra of thick frosts and transmission spectra of thin films are shown, and their main characteristics are described. Hydrates, clathrates, and composite spectra are discussed. When it is possible to observe the nuclei of comets at close range, it may be possible to identify frozen volatiles by their infrared spectra.

Full Text Available Abstract Background Artificial insemination (AI using frozen-thawed semen is well established and routinely used for breeding in various mammalian species. However, there is no report of the birth of elephant calves following AI with frozen-thawed semen. The objective of the present study was to investigate the fertilizing ability of chilled and frozen-thawed semen in the Asian elephant following artificial insemination (AI. Methods Semen samples were collected by from 8 bulls (age range, 12-to 42-years by manual stimulation. Semen with high quality were either cooled to 4°C or frozen in liquid nitrogen (-196°C before being used for AI. Blood samples collected from ten elephant females (age range, 12-to 52-years were assessed for estrus cycle and elephants with normal cycling were used for AI. Artificial insemination series were conducted during 2003 to 2008; 55 and 2 AI trials were conducted using frozen-thawed and chilled semen, respectively. Pregnancy was detected using transrectal ultrasonography and serum progestagen measurement. Results One female (Khod inseminated with chilled semen became pregnant and gave birth in 2007. The gestation length was 663 days and the sex of the elephant calf was male. One female (Sao inseminated with frozen-thawed semen showed signs of pregnancy by increasing progestagen levels and a fetus was observed for 5 months by transrectal ultrasonography. Conclusion This is the first report showing pregnancy following AI with frozen-thawed semen in the Asian elephant. Successful AI in the Asian elephant using either chilled or frozen-thawed semen is a stepping stone towards applying this technology for genetic improvement of the elephant population.

The diabetic frozen shoulder: arthroscopic release.

Ogilvie-Harris, D J; Myerthall, S

1997-02-01

Seventeen patients who were diabetics developed frozen shoulders which failed to respond to conservative management. They had persistent pain, stiffness, and limited function. An arthroscopic release was performed by progressively releasing the anterior structures from superior to inferior. Starting from the interval area we progressed to the anterior superior glenohumeral ligament, the intra-articular portion of the subscapularis, the anterior capsule, and the inferior capsule. Postoperatively physiotherapy was carried out daily to maintain the range of movement. At a follow up of 1 to 5 years the patients were assessed using the American Shoulder Society scheme. In addition the patients were assessed preoperatively and postoperatively on four criteria; pain, external rotation, abduction, and function. We found that the patients were statistically significantly improved in all four categories. Thirteen of the 17 patients had no pain, full range of motion compared with the opposite side, and full function. There was one poor result with no improvement. The remaining three patients had improved but still had residual abnormalities. We consider arthroscopic release to be an effective treatment for the resistant diabetic frozen shoulder.

Parenting styles, feeding styles, and their influence on child obesogenic behaviors and body weight. A review.

Science.gov (United States)

Vollmer, Rachel L; Mobley, Amy R

2013-12-01

With recommendations to include parents as targets for childhood obesity interventions, there is a need to review the relationship of general parenting influences on childhood obesity. Therefore, the aim of this review is to examine the existing literature regarding the influence of parenting style and/or feeding styles on childhood obesogenic behaviors and body weight. Research articles related to parenting style (n=40) and parental feeding style (n=11) were identified and reviewed. An authoritative style appears to be the most protective parenting and feeding style while the indulgent feeding style is consistently associated with negative health outcomes. Overall, results for parenting style studies are inconsistent due to differences in conceptualization and measurement, while the results for feeding styles are much more cohesive. The literature is lacking in the ability to describe the interplay between parenting and feeding styles and child obesity risk. Recommendations for future research and interventions are discussed in regards to feeding style and influences on childhood obesity. Copyright © 2013 Elsevier Ltd. All rights reserved.

Determination of blood cell subtype concentrations from frozen whole blood samples using TruCount beads.

In many studies it would be advantageous if blood samples could be collected and analyzed using flow cytometry at a later stage. Ideally, sample collection should involve little hands-on time, allow for long-term storage, and minimally influence the samples. Here we establish a flow cytometry antibody panel that can be used to determine granulocytes, monocytes, and lymphocyte subset concentrations in fresh and frozen whole blood using TruCount technology. The panel can be used on fresh whole-blood samples as well as whole-blood samples that have been frozen after mixing with 10% DMSO. Concentrations in frozen and fresh sample is highly correlated both when frozen within 4 h and the day after collection (r ≥ 0.98), and the estimated concentration in frozen samples was between 91 and 94% of that in fresh samples for all cell types. Using this method whole-blood samples can be frozen using a simple preparation method, and stored long-term before accurate determination of cell concentration. This allows for standardized analysis of the samples at a reference laboratory in multi-center studies. © 2016 International Clinical Cytometry Society. © 2016 International Clinical Cytometry Society.

Studies on Rapidly Frozen Suspensions of Yeast Cells by Differential Thermal Analysis and Conductometry

Science.gov (United States)

Mazur, Peter

1963-01-01

Few, if any, yeast cells survived rapid cooling to -196°C and subsequent slow warming. After rapid freezing, the suspensions absorbed latent heat of fusion between -15° and 0°C during warming, and the relation between the amount of heat absorbed and the concentration of cells was the same as that in equivalent KCl solutions, indicating that frozen suspensions behave thermally like frozen solutions. The amount of heat absorbed was such that more than 80 per cent of the intracellular solution had to be frozen. The conductometric behavior of frozen suspensions showed that cell solutes were still inside the cells and surrounded by an intact cell membrane at the time heat was being absorbed. Two models are consistent with these findings. The first assumes that intracellular freezing has taken place; the second that all freezable water has left the cells and frozen externally. The latter model is ruled out because rapidly cooled cells do not shrink by an amount equal to the volume of water that would have to be withdrawn to prevent internal freezing. PMID:13934216

Previous studies have identified a predominant learning style in trainees from different specialties, more recently in otolaryngology residents. The purpose of our study was to determine a predominant learning style within otolaryngology fellowships and to identify any differences between otolaryngology fellows and residents. We conducted a survey of otolaryngology fellows at 25 otolaryngology fellowship programs accredited by the Accreditation Council for Graduate Medical Education. We emailed Kolb's Learning Style Index version 3.1 to 16 pediatric otolaryngology (PO) and 24 otology/neurotology (ON) fellows. This index is a widely used 12-item questionnaire. The participants answered each item in the questionnaire as it applied to their preferred learning style: accommodating, converging, diverging, or assimilating. Results were then analyzed and compared between each subspecialty and the previously reported preferred styles of otolaryngology residents. Ten PO and 20 ON fellows completed the survey, with an overall response rate of 75%. PO and ON fellows (60% of each group) preferred a learning style that was "balanced" across all four styles. For ON fellows, 35% preferred converging and 5% preferred accommodating styles. For PO fellows, converging and accommodating styles accounted for 20% each. It was previously reported that 74.4% of otolaryngology residents prefer either converging or accommodating styles. We believe that the fellowship training environment calls for fellows to use more than one learning style to become proficient physicians, hence the trend toward potentially developing a balanced style when at this level.

This study examined long-term follow-up effects of participation in the HomeStyles RCT, using Social Cognitive Theory constructs, on physical activity cognitions, home environment, and lifestyle behavioral practices of families with preschool children (ages 2 to 5 years). Parents were systematically randomized to experimental or attention control group at baseline. Those completing all surveys that comprised of valid, reliable measures were the analytic sample (n = 61 experimental, n = 63 control; mean age 32.8 ± 5.9SD years). Repeated measures ANCOVA, controlling for prognostic variables (e.g., parent sex) revealed that variables assessing modeling of physical activity for children increased significantly (P ≤ .01) in both groups with no significant time by group effects. Paired t-tests indicated the experimental group's self-efficacy for keeping children's weight healthy and performing health promoting behaviors increased significantly over time whereas the control group did not but with no significant time by group effects. Self-regulation paired t-test findings indicated that total screentime the experimental group allowed children decreased significantly over time with no significant time by group effect. The value parents placed on physical activity for children increased over time in both groups with a significant time effect. The experimental group over time had significantly greater increases in the availability of physical activity space and supports inside the home than the control group. Improvements noted have the potential to help protect children and parents from excess weight gain, yet findings indicate considerable opportunity for continued improvement as well as elucidation of factors affecting concomitant changes in both study groups.

2018-02-01

Cuttlefish ink is consumed as a delicacy worldwide. The current study is the first assessment of heavy metal concentrations in cuttlefish ink versus mantle under different storage methods. A total of 212 samples (64 of fresh mantle, 42 of frozen mantle, 64 of fresh ink, and 42 of frozen ink) were analyzed for the detection of the following heavy metals: arsenic (As), chromium (Cr), iron (Fe), lead (Pb), mercury (Hg), and cadmium (Cd). The median As concentrations were 12.9 mg/kg for fresh mantle, 8.63 mg/kg for frozen mantle, 10.8 mg/kg for frozen ink, and 0.41 mg/kg for fresh ink. The median Cr concentrations were 0.06 mg/kg for fresh mantle and frozen ink, 0.03 mg/kg for frozen mantle, and below the limit of quantification (LOQ) for fresh ink. The median Fe concentrations were 4.08 mg/kg for frozen ink, 1.51 mg/kg for fresh mantle, 0.73 mg/kg for frozen mantle, and below the LOQ for fresh ink. The median Pb concentrations of almost all samples were below the LOQ; only two frozen ink, one fresh ink, one frozen mantle, and one fresh mantle sample exceeded the limit stipulated by the European Union. The Hg concentrations were statistically similar among the four categories of samples; the median Hg concentrations were below the LOQ, and the maximum concentrations were found in frozen ink, at 1.62 mg/kg. The median Cd concentrations were 0.69 mg/kg for frozen ink and 0.11 mg/kg for frozen mantle, fresh mantle and fresh ink concentrations were below the LOQ, and in 11.3% of the tested samples, Cd concentrations were higher than the European Union limit. The probability of samples having a Cd concentration above the legal limit was 35.75 times higher in frozen than in fresh products. Fresh ink had significantly lower concentrations of As, Cr, Fe, and Cd, but the concentrations of Hg and Pb were not significantly different from those of other products. Frozen ink had significantly higher concentrations of Cd, Cr, and Fe, but concentrations of As were lower than those in

Style and creativity in design

CERN Document Server

Chan, Chiu-Shui

2015-01-01

This book looks at causative reasons behind creative acts and stylistic expressions. It explores how creativity is initiated by design cognition and explains relationships between style and creativity. The book establishes a new cognitive theory of style and creativity in design and provides designers with insights into their own cognitive processes and styles of thinking, supporting a better understanding of the qualities present in their own design.  An explanation of the nature of design cognition begins this work, with a look at how design knowledge is formulated, developed, structured and utilized, and how this utilization triggers style and creativity. The author goes on to review historical studies of style, considering a series of psychological experiments relating to the operational definition, degree, measurement, and creation of style. The work conceptually summarizes the recognition of individual style in products, as well as the creation of such styles as a process before reviewing studies on cr...

Hua Zhang

2017-01-01

Full Text Available In this paper, the effects of Bamboo shoot dietary fiber (BSDF on the mechanical properties, moisture distribution, and microstructure of frozen dough were investigated. The state and distribution of water in frozen dough was determined by differential scanning calorimetry (DSC and low-field nuclear magnetic resonance (LNMR spectroscopy. The microstructure of frozen dough was studied. The structure of the gluten protein network found in wheat flour dough was studied by scanning electron microscopy (SEM. The result showed that the BSDF could significantly improve the viscoelasticity and extensibility of frozen dough after thawing in a dose-dependent manner. It was significantly improved with the increase in the addition amount of BSDF (P<0.05. DSC analysis showed that the freezable water content and thermal stability of frozen dough were increased after the addition of BSDF. LNMR analysis showed that the appropriate (<0.1% addition amount of BSDF could significantly (P<0.05 decline the contents of bound water. Meanwhile, the loose bound water and free water were raised significantly (P<0.05 after the addition of BSDF. Moreover, the addition of BSDF induces arrangement of starch granule and gluten network in frozen dough. BSDF can be used as a novel quality improver of frozen dough.

2009-01-01

Limited data are available to evaluate the accuracy of frozen section analysis and ultrasound- guided core needle biopsy of the breast. In a retrospective analysis data of 120 consecutive handheldultrasound- guided 14- gauge automated core needle biopsies (CNB) in 109 consecutive patients with breast lesions between 2006 and 2007 were evaluated. In our outpatient clinic120 CNB were performed. In 59/120 (49.2%) cases we compared histological diagnosis on frozen sections with those on paraffin sections of CNB and finally with the result of open biopsy. Of the cases 42/59 (71.2%) were proved to be malignant and 17/59 (28.8%) to be benign in the definitive histology. 2/59 (3.3%) biopsies had a false negative frozen section result. No false positive results of the intraoperative frozen section analysis were obtained, resulting in a sensitivity, specificity and positive predicting value (PPV) and negative predicting value (NPV) of 95%, 100%, 100% and 90%, respectively. Histological and morphobiological parameters did not show up relevance for correct frozen section analysis. In cases of malignancy time between diagnosis and definitive treatment could not be reduced due to frozen section analysis. The frozen section analysis of suspect breast lesions performed by CNB displays good sensitivity/specificity characteristics. Immediate investigations of CNB is an accurate diagnostic tool and an important step in reducing psychological strain by minimizing the period of uncertainty in patients with breast tumor

Loureiro, Elizabete; McIntyre, Teresa; Mota-Cardoso, Rui; Ferreira, Maria Amélia

2008-01-01

Different studies have demonstrated that there are significant changes in the health and habits/life-style of university students, and it seems that Medical students also reveal a significant vulnerability to the adoption of health risk behaviours. The present study aims to (1) characterize the main sources of academic stress of the Medical School students of the University of Porto as well as the intensity with which they are experienced, (2) investigate the variations in academic stress and psychosocial variables, due to gender, year of course and displacement from home and (3) contribute, for the first time, to the understanding of stress and life-style of medical students in Portugal. The empirical study included a sample of 251 students from all 6 years of the course (160 females and 91 males), evaluated by the following instruments: (1) The Inventory of Sources of Academic Stress in Medical Education (ISASME), and the Portuguese versions of (2) the Brief Personal Survey (BPS), (3) the General Health Questionnaire 12 (GHQ-12), and (4) the Interpersonal Behaviour Survey-Brief (ICIBrief). In terms of overall levels of stress (GHQ-12), a prevalence of 58.2% of clinically significant stress symptoms was found, with the students from the basic cycle and those who are living away from home, presenting higher levels of stress. In terms of life-style, 47% of the students revealed health risk behaviours, with eating habits, physical exercise, alcohol and drug consumption, and body image being the main problem areas. Gender and year of course seem to have a significant influence on the variables studied, being the female students those who present higher levels of academic stress, stress responses (pressure/overload, physical distress, anxiety, anger/frustration, inefficiency, depression and loss of control), and low levels of coping confidence; the students of the basic cycle reveal higher levels of stress in managing their life-style (academic stress), general stress

Bechmann, Iben Ellegaard; Jensen, H.S.; Bøknæs, Niels

1998-01-01

Physical, chemical and sensory quality parameters were determined for 115 cod (Gadus morhua) samples stored under varying frozen storage conditions. Five different process parameters (period of frozen storage, frozen storage. temperature, place of catch, season for catching and state of rigor) were...... varied systematically at two levels. The data obtained were evaluated using the multivariate methods, principal component analysis (PCA) and partial least squares (PLS) regression. The PCA models were used to identify which process parameters were actually most important for the quality of the frozen cod....... PLS models that were able to predict the physical, chemical and sensory quality parameters from the process parameters of the frozen raw material were generated. The prediction abilities of the PLS models were good enough to give reasonable results even when the process parameters were characterised...

Socioeconomic Status, Parenting, and Externalizing Problems in African American Single-Mother Homes: A Person-Oriented Approach

2016-01-01

African American youth, particularly those from single-mother homes, are overrepresented in statistics on externalizing problems. The family is a central context in which to understand externalizing problems; however, reliance on variable-oriented approaches to the study of parenting, which originate from work with intact, middle-income, European American families, may obscure important information regarding variability in parenting styles among African American single mothers, and in turn, variability in youth outcomes as well. The current study demonstrated that within African American single-mother families: (a) a person-, rather than variable-, oriented approach to measuring parenting style may further elucidate variability; (b) socioeconomic status may provide 1 context within which to understanding variability in parenting style; and (c) 1 marker of socioeconomic status, income, and parenting style may each explain variability in youth externalizing problems; however, the interaction between income and parenting style was not significant. Findings have potential implications for better understanding the specific contexts in which externalizing problems may be most likely to occur within this at-risk and underserved group.

The crucial role of the micro caregiving environment: Factors associated with attachment styles in alternative care in Chile.

Science.gov (United States)

Garcia Quiroga, Manuela; Hamilton-Giachritsis, Catherine

2017-08-01

The distribution of attachment styles has been shown to differ between groups of children living with their parents and children placed in alternative care (AC), defined as residential or foster. However, this is the first study in Latin America to explore possible factors affecting the quality of attachment in children living in both residential and foster care. Two groups of children (N=57) were compared: one group living in Residential Homes (RC) and the other in Foster Care (FC) in Chile. Children's, caregivers' and structural factors (e.g., child: caregiver ratios) and their links with attachment styles were investigated. The micro caregiving environment (i.e., the specific individual child caregiver relationship), especially the caregivers' engagement, sensitivity, disciplinary control and affection, as well as some structural factors (i.e., child: caregiver ratios), were linked to attachment security in children. Specifically, better emotional caregiving and lower child-caregiver ratios were associated with higher rates of secure attachment. The association between quality of care (as measured by the HOME inventory) and attachment styles seems to be influenced by caregiver relationships (as measured by CCSERSS). Caregiver relationship factors (i.e., affection, engagement and sensitivity) directly impact the quality of the attachment children establish with them while living in AC. However, the relationships that caregivers establish with children under their care can be facilitated by good quality structural factors, particularly child-caregiver ratios.

Gakumon-Ryoku and japanese style of management- does our management style matter?

Directory of Open Access Journals (Sweden)

Oba Hiroyuki

2010-05-01

Full Text Available This paper highlights a new style of development learning, the so-called “Gakumon-ryoku”, and its application to the Japanese style of management. “Gakumon-ryoku” is the capability and commitment or free-will to awaken and share freedom lifestyles by learning and asking about our thoughts and feelings through the Value-Conscious Matrix VC Matrix or simply VCM for short.This enlightens and vitalizes our thoughts and feelings, and can transform us by creating a new identity for us as Development of Co-creative Alive Beings, or D-CAB. This eye-opening experience was examined with the Japanese style of management (JM in short and has brought us to become aware of the essence of JM spirit of TO BE ONE. To the question, “does our management style matter”, this paper has answered “Yes”, not because this is not economically or rationally efficient, but because it has been confined to it and has not been examined in the light of the JOY criterion including efficiency. What really matters is not whether or not to follow the Japanese style, but the fact that the quality of life, or Joyful or not matters in our management style. We learn that the Japanese style of management has both unique and universal features, and we, as human beings, can share its universal value of JOY of service.

Frozen shoulder contracture syndrome - Aetiology, diagnosis and management.

Science.gov (United States)

Lewis, Jeremy

2015-02-01

Frozen shoulder is a poorly understood condition that typically involves substantial pain, movement restriction, and considerable morbidity. Although function improves overtime, full and pain free range, may not be restored in everyone. Frozen shoulder is also known as adhesive capsulitis, however the evidence for capsular adhesions is refuted and arguably, this term should be abandoned. The aim of this Masterclass is to synthesise evidence to provide a framework for assessment and management for Frozen Shoulder. Although used in the treatment of this condition, manipulation under anaesthetic has been associated with joint damage and may be no more effective than physiotherapy. Capsular release is another surgical procedure that is supported by expert opinion and published case series, but currently high quality research is not available. Recommendations that supervised neglect is preferable to physiotherapy have been based on a quasi-experimental study associated with a high risk of bias. Physiotherapists in the United Kingdom have developed dedicated care pathways that provide; assessment, referral for imaging, education, health screening, ultrasound guided corticosteroid and hydro-distension injections, embedded within physiotherapy rehabilitation. The entire pathway is provided by physiotherapists and evidence exists to support each stage of the pathway. Substantial on-going research is required to better understand; epidemiology, patho-aetiology, assessment, best management, health economics, patient satisfaction and if possible prevention.

Sterile ice cream and frozen yogurt were offered to immunosuppressed patients recovering from bone marrow transplantation. To obtain sterile products, two of the dairy desserts (prepackaged ice cream and frozen yogurt bars) were exposed to 40 kGy of cobalt 60 irradiation. Four different flavors of ice cream were aseptically prepared under a laminar airflow hood using commercially sterilized ingredients. A commercially sterile, frozen milk-based drink on the low-microbial menu served as the control. Ratings of the seven products by 17 patients indicated that a frozen vanilla milk-based drink and aseptically prepared chocolate ice cream were highly acceptable to recovering immunosuppressed patients who have difficulty eating most foods. However, the seven desserts received higher ratings from a sensory panel of healthy individuals than from the patient panel, confirming that new foods for the low-microbial diet should be ''market-tested'' by the targeted patient population before inclusion in the menu

Izutsu, Ken-ichi; Rimando, Annie; Aoyagi, Nobuo; Kojima, Shigeo

2003-06-01

The effect of sodium tetraborate (Na(2)B(4)O(7), borax) on the thermal property of frozen aqueous sugar and polyol solutions was studied through thermal analysis. Addition of borax raised the thermal transition temperature (glass transition temperature of maximally freeze-concentrated solutes; T(g)') of frozen sucrose solutions depending on the borax/sucrose concentration ratios. Changes in the T(g)' of frozen mono- and disaccharide solutions suggested various forms of complexes, including those of a borate ion and two saccharide molecules. Borax exerted the maximum effect to raise the oligosaccharide and dextran T(g)'s at borax/saccharide molar ratios of approximately 1-2 (maltose and maltooligosaccharides), 2 (dextran 1060), 5 (dextran 4900), and 10 (dextran 10200). Further addition of borax lowered T(g)'s of the saccharide solutions. Borax also raised T(g) and T(g)' temperatures of frozen aqueous glycerol solutions. The decreased solute mobility in frozen solutions by the borate-polyol complexes suggested higher collapse temperature in the freeze-drying process and improved stability of biological systems in frozen solutions.

The objective of this study was to investigate the effect of freeze-thaw cycles, which may occur in the cold chain, on colour (Lab, Total Colour Differences (TCD, chroma and hue angle and vitamin C (ascorbic and dehydroascorbic acids content of frozen strawberries (Fragaria ×ananassa, Duschesne, cv. Selva. A plan of temperature abuses (TAs was established, based on a real situation, and applied to frozen strawberries during a four month frozen storage period. The results showed that the lightness (L was the only parameter that was not significantly affected by range of TAs studied. The colour showed some variation on the parameters a, b, TCD, chroma and hue angle. During TAs, ascorbic acid decreased about 75% and dehydroascorbic acid increased 73%. The non-abused strawberry samples showed better overall appearance than the abused samples. This work contributes to an understanding of the quality changes of frozen strawberries that might occur during frozen storage and cold chain distribution.

Style representation in design grammars

Ahmad, Sumbul; Chase, Scott Curland

2012-01-01

The concept of style is relevant for both the analysis and synthesis of designs. New styles are often formed by the adaptation of previous ones based on changes in design criteria and context. A formal characterization of style is given by shape grammars, which describe the compositional rules...... underlying a set of designs. Stylistic change can be modelled by grammar transformations, which allow the transformation of the structure and vocabulary of a grammar that is used to describe a particular style. In order for grammars to be useful beyond a single application, they should have the capability...... to be transformed according to changing design style needs. Issues of formalizing stylistic change necessitate a lucid and formal definition of style in the design language generated by a grammar. Furthermore, a significant aspect of the definition of style is the representation of aesthetic qualities attributed...

Effect of freezing temperature on the color of frozen salmon.

Ottestad, Silje; Enersen, Grethe; Wold, Jens Petter

2011-09-01

New freezing methods developed with the purpose of improved product quality after thawing can sometimes be difficult to get accepted in the market. The reason for this is the formation of ice crystals that can give the product a temporary color loss and make it less appealing. We have here used microscopy to study ice crystal size as a function of freezing temperature by investigating the voids in the cell tissue left by the ice crystals. We have also investigated how freezing temperature affects the color and the visible absorption spectra of frozen salmon. Freezing temperatures previously determined to be the best for quality after thawing (-40 to -60 °C) were found to cause a substantial loss in perceived color intensity during frozen state. This illustrated the conflict between optimal freezing temperatures with respect to quality after thawing against visual appearance during frozen state. Low freezing temperatures gave many small ice crystals, increased light scattering and an increased absorption level for all wavelengths in the visible region. Increased astaxanthin concentration on the other hand would give higher absorption at 490 nm. The results showed a clear potential of using visible interactance spectroscopy to differentiate between poor product coloration due to lack of pigmentation and temporary color loss due to light scattering by ice crystal. This type of measurements could be a useful tool in the development of new freezing methods and to monitor ice crystal growth during frozen storage. It could also potentially be used by the industry to prove good product quality. In this article we have shown that freezing food products at intermediate to low temperatures (-40 to -80 °C) can result in paler color during frozen state, which could affect consumer acceptance. We have also presented a spectroscopic method that can separate between poor product color and temporary color loss due to freezing. © 2011 Institute of Food Technologists®

2012-05-01

Full Text Available Frozen yogurt is a frozen fermented dessert which presents structural characteristics similar to ice cream and nutritional and sensorial properties which resemble to yogurt. The acidification of ice cream mix by means of lactic bacteria can influence the properties of frozen yogurt. For that reason, the present work aimed to evaluate the influence of pH on the physicochemical and sensorial characteristics of strawberry frozen yogurt. The formulation consisted of 6 % of milk fat, 10 % of milk solids-not-fat, 11 % of sucrose, 3 % of corn syrup, 0.3 % of emulsifiers and 0.5 % of stabilizers. The frozen yogurt mixes were made with different fermentation endpoints, pH values of 4.5, 5.0 and 5.5. The strawberry fruit mixture was added to the fermented frozen yogurt mix at a level of 4 % (w/w. According to the results, the pH of the frozen yogurt mix did not influence the concentrations of protein, fat and ash whereas the contents of acidity, reducing, non-reducing and total sugars underwent influence of pH due to fermentation. The acceptability of frozen yogurt in relation to the attributes flavor, texture, overall acceptance and ideal acidity was evaluated. It was found that pH influenced the acceptance of frozen yogurt; the treatments with final pH of 5.0 and 5.5 presented higher acceptability for all the treatments evaluated and acidity close to the ideal.

Full Text Available On the sample by 121 perspective young athletes was carried out the researching in the aim to establish the behavior style of coaches. The relevant information was obtained through the validated questionnaires of Chelladura and Saleha (1980. The questionnaire contains 40 questions which directly determine 5 behavior styles of coaches. All questions possess the scale by 5 levels with possible statements: (always, often, periodically, rarely and never. The true answer is only one statement on one question. It is word about five degrees 'Likert's scale'. It was carried out extensive and complex statistics processing of date, where the input qualitative categorical variables were transformed into quantitative. In the next step, transformed categorical variables were exposed in classical and neoclassical statistical methodology. On the base of exact indications which were obtained by using relevant invariant and multivariate statistical methods and tests, dominant behavior style of coaches is 'Instructive'. This behavior style of coach is the most desirable. According to this researching at the last position is behavior style which is the autocratically and it is also at the same time the least desirable. The results of Analysis of variance (ANOVA and Canonic discriminative analysis show the general statistical significant difference in the representation of the behavior styles. Instructive and Autocratic behavior style of coach mostly influences on the total (general discrimination i.e. difference. For above mentioned styles, it could be said that they are paradigm of contrasts in every way. Values of Tukey - HSD test explicitly shows that there are not statistical significant difference between Instructive Style and style Awarded - Feedback as well as between Democratically and style of Social Support. The other combinations i.e. couples of behavior styles are statistical significantly different.

Psychrophiles and astrobiology: microbial life of frozen worlds

Science.gov (United States)

Pikuta, Elena V.; Hoover, Richard B.

2003-01-01

Most bodies of our Solar System are "Frozen Worlds" where the prevailing surface temperature remains at or below freezing. On Earth there are vast permanently frozen regions of permafrost, polar ice sheets, and glaciers and the deep oceans and deep-sea marine sediments have remained at 2 - 4°C for eons. Psychrophilic and psychrotrophic microbiota that inhabit these regimes provide analogs for microbial life that might inhabit ice sheets and permafrost of Mars, comets, or the ice/water interfaces or sediments deep beneath the icy crusts of Europa, Callisto, or Ganymede. Cryopreserved micro-organisms can remain viable (in a deep anabiotic state) for millions of years frozen in permafrost and ice. Psychrophilic and psychrotrophic (cold-loving) microbes can carry out metabolic processes in water films and brine, acidic, or alkaline chanels in permafrost or ice at temperatures far below 0°C. These microbes of the cryosphere help define the thermal and temporal limits of life on Earth and may provide clues to where and how to search for evidence of life elsewhere in the Cosmos. Astrobiologists at the NASA Marshall Space Flight Center have collected microbial extremophiles from the Pleistocene ice wedges and frozen thermokarst ponds from the Fox Permafrost Tunnel of Alaska. Microbes have also been isolated from samples of Magellanic Penguin guano from Patagonia; deep-sea marine muds near hydrothermal vents; snow and permafrost from Siberia, and deep ice cores, ice-bubble and cryoconite rocks of the Central Antarctic Ice Sheet. These samples have yielded microbial extremophiles representing a wide variety of anaerobic bacteria and archaea. These microbes have been isolated, cultured, characterized and analyzed by phylogenetic and genomic methods. Images were obtained by Phase Contrast, Environmental, Field Emission Scanning and Transmission Electron Microscopes to study the ultra-microstructure and elemental distribution in the composition of these micro-organisms.

Valeria Califano

2017-12-01

Full Text Available Candida rugosa lipase (CRL was deposited by matrix assisted pulsed laser evaporation (MAPLE in order to immobilize the enzyme with a preserved native conformation, which ensures its catalytic functionality. For this purpose, the composition of the MAPLE target was optimized by adding the oil phase pentane to a water solution of the amino acid 3-(3,4-dihydroxyphenyl-2-methyl-l-alanine (m-DOPA, giving a target formed by a frozen water-lipase-pentane microemulsion. Fourier transform infrared (FTIR spectroscopy and atomic force microscopy (AFM were used to investigate the structure of MAPLE deposited lipase films. FTIR deconvolution of amide I band indicated a reduction of unfolding and aggregation, i.e., a better preserved lipase secondary structure in the sample deposited from the frozen microemulsion target. AFM images highlighted the absence of big aggregates on the surface of the sample. The functionality of the immobilized enzyme to promote transesterification was determined by thin layer chromatography, resulting in a modified specificity.

Full Text Available Background and purpose: Learning style is the processing of information and comprehension. If teachers present contents in a style that matches a student’s preferred learning style, academic performance and success will improve. If content retention improves it will result in an increase in thetest scores. It is also important to determine if students, as a group, fit into a particular style or a particular cycle as they move through an educational program.Methods: The study is a descriptive analytical research. Nursing Students at Isfahan Medical Sciences University completed a questionnaire  formulated to assess learning styles. Analysis of variance was used to investigate the possible relationship between learning cycle and student’s grades in the curriculum (i.e. freshman, sophomore, junior, or senior. Cross tabulation was used to test for a relationship between learning style and student academic year of study in the curriculum.Results: 294 students received the Kolb LSI questionnaire. The data demonstrated that juniors preferred a converger learning style and the senior students were in the abstract conceptualization cycle of learning. There were no relationships demonstrated between other groups in the study.Conclusion: The junior and senior students appear to prefer the stage of learning involving thinking and problem analysis. When a group of students demonstrate a preference for particular learning style teachers can develop their curriculum along their learning styleKey words: LEARNING STYLES, NURSING STUDENTS, FRESHMAN, SOPHOMORE, JUNIOR, SENIOR

We assessed the rate of recovery of fluoroquinolone-resistant and fluoroquinolone-susceptible Escherichia coli isolates from culture of frozen perirectal swab samples compared with the results for culture of the same specimen before freezing. Recovery rates for these 2 classes of E. coli were 91% and 83%, respectively. The majority of distinct strains recovered from the initial sample were also recovered from the frozen sample. The strains that were not recovered were typically present only in low numbers in the initial sample. These findings emphasize the utility of frozen surveillance samples.

The home care workforce, already at 2.7 million caregivers, will become the nation's fastest growing occupation by 2024 as the senior boom generation accelerates the demand for in home services to meet its long-term care needs. The physically challenging work of assisting clients with intimate, essential acts of daily living places home care workers (HCWs) at risk for musculoskeletal disorders (MSDs); yet, HCWs typically receive little formal job training and may lack appropriate assistive devices. In this qualitative pilot study, HCW focus groups described workplace MSD risk factors and identified problem-solving strategies to improve ergonomic conditions. The results revealed that HCWs rely on their behavioral insights, self-styled communications skills and caring demeanor to navigate MSD risks to themselves and increase clients' physical independence of movement. We suggest changes in employer and government policies to acknowledge HCWs as valued team members in long-term care and to enhance their effectiveness as caregivers.

Backman, Annica; Sjögren, Karin; Lövheim, Hugo; Edvardsson, David

2018-04-01

To explore the association between nursing home managers' leadership, job strain and social support as perceived by direct care staff in nursing homes. It is well known that aged care staff experience high levels of job strain, and that aged care staff experiencing job strain are exposed to increased risk for adverse health effects. Leadership styles have been associated with job strain in the literature; however, the impact of perceived leadership on staff job strain and social support has not been clarified within nursing home contexts. This study had a cross-sectional design. Participating staff (n = 3,605) completed surveys which included questions about staff characteristics, valid and reliable measures of nursing home managers' leadership, perceived job strain and social support. Statistical analyses of correlations and multiple regression analysis with interaction terms were conducted. Nursing home managers' leadership were significantly associated with lower level of job strain and higher level of social support among direct care staff. A multiple regression analysis including an interaction term indicated individual and joint effects of nursing home managers' leadership and social support on job strain. Nursing home managers' leadership and social support were both individually and in combination associated with staff perception of lesser job strain. Thus, nursing home managers' leadership are beneficial for the working situation and strain of staff. Promoting a supporting work environment through leadership is an important implication for nursing home managers as it can influence staff perception of job strain and social support within the unit. By providing leadership, offering support and strategies towards a healthy work environment, nursing home managers can buffer adverse health effects among staff. © 2017 John Wiley & Sons Ltd.

Frozen blood products: clinically effective and potentially ideal for remote Australia.

2013-01-01

The development of effective cryopreservation techniques for both red blood cells and platelets, which maintain ex vivo biological activity, in combination with frozen plasma, provides for a unique blood banking strategy. This technology greatly enhances the storage life of these products. The rationale and potential advantages of using cryopreservation techniques for the provision of blood products to remote and military environments have been effectively demonstrated in several conflicts over the last decade. Current haemostatic resuscitation doctrine for the exsanguinating patient supports the use of red blood cells, platelets and frozen plasma early in the resuscitation. We believe an integrated fresh-frozen blood bank inventory could facilitate provision of blood products, not only in the military setting but also in regional Australia, by overcoming many logistic and geographical challenges. The processes involved in production and point of care thawing are sufficiently well developed and achievable to make this technology a viable option. The potential limitations of cryopreservation and subsequent product thawing need to be considered if such a strategy is to be developed. A substantial body of international experience using cryopreserved products in remote settings has already been accrued. This experience provides a template for the possible creation of an Australian integrated fresh-frozen blood bank inventory that could conceivably enhance the care of patients in both regional Australia and in the military setting.

The objective of this study was to investigate serial changes for histology of joint capsule and range of motion of the glenohumeral joint after immobilization in rats. We hypothesized that a rat shoulder contracture model using immobilization would be capable of producing effects on the glenohumeral joint similar to those seen in patients with frozen shoulder. Sixty-four Sprague-Dawley rats were randomly divided into one control group (n = 8) and seven immobilization groups (n = 8 per group) that were immobilized with molding plaster for 3 days, or for 1, 2, 3, 4, 5, or 6 weeks. At each time point, eight rats were euthanized for histologic evaluation of the axillary recess and for measurement of the abduction angle. Infiltration of inflammatory cells was found in the synovial tissue until 2 weeks after immobilization. However, inflammatory cells were diminished and fibrosis was dominantly observed in the synovium and subsynovial tissue 3 weeks after immobilization. From 1 week after immobilization, the abduction angle of all immobilization groups at each time point was significantly lower than that of the control group. Our study demonstrated that a rat frozen shoulder model using immobilization generates the pathophysiologic process of inflammation leading to fibrosis on the glenohumeral joint similar to that seen in patients with frozen shoulder. This model was attained within 3 weeks after immobilization. It may serve as a useful tool to investigate pathogenesis at the molecular level and identify potential target genes that are involved in the development of frozen shoulder.

Full Text Available In order to motivate their group members to perform certain tasks, leaders use different leadership styles. These styles are based on leaders' backgrounds, knowledge, values, experiences, and expectations. The one-dimensional styles, used by many world leaders, are autocratic and democratic styles. These styles lie on the two opposite sides of the leadership spectrum. In order to precisely define the leadership styles on the spectrum between the autocratic leadership style and the democratic leadership style, leadership theory researchers use two dimensional matrices. The two-dimensional matrices define leadership styles on the basis of different parameters. By using these parameters, one can identify two-dimensional styles.

2002-06-01

To investigate whether parenting style is an independent risk factor of smoking initiation and experimentation among adolescents, and whether there is a relationship between parenting style and readiness to quit, or nicotine dependence among smokers. The 84-item Health and Smoking Questionnaire, which assesses demographics, smoking status and smoking history, perceptions of risk and risk reduction, risk factors for tobacco use, and parenting style, was administered to 816 adolescents in grades 7 to 12 (mean age, 15.1 years) of whom 22.6% (n = 182) were smokers. Parenting style was measured by the brief, non-retrospective version of the Family of Origin Scale (FOS). Higher scores on the FOS indicated more positive perceived parenting style with high levels of intimacy and autonomy, characteristics of healthy parent-child relationships. Data were analyzed using a model-building approach to logistic regression with demographic and other psychosocial variables in the first two steps, and with parenting style as the last step. Results from two logistic regression models indicate that although parenting style is not a significant risk factor for smoking experimentation [odds ratio (OR) =.998; confidence interval (CI) =.977-1.019; p =.820], it is a significant independent risk factor for smoking initiation (OR =.950; CI =.930-.970; p =.000). Smokers who were more ready to quit had higher parenting style scores than those who were not ready to quit, and smokers who had made a serious quit attempt (an indicator of nicotine addiction) had higher parenting style scores than those who had not made a quit attempt. Moreover, nonsmokers who reported they would smoke a cigarette if their best friend offered had significantly lower parenting style scores than those who reported they would not smoke a cigarette. Additional research on parenting style and its impact on adolescent smoking with a more economically and ethnically diverse sample is warranted. If future research confirms

2008-09-01

Historically, artificial insemination (AI) using frozen semen has been perceived to have poorer success rates and be more labour intensive than using chilled semen. A retrospective study was therefore conducted to compare the conception rate achieved by AI between chilled and frozen semen, using fixed time insemination protocols over 2 breeding seasons. Artificial insemination using chilled semen produces a higher conception rate than that achieved with frozen semen. Mares (n = 251) were inseminated with either chilled (n = 112) or frozen (n = 139) semen in the 2006 and 2007 northern hemisphere breeding season. Per rectum ultrasonography of the mare's reproductive tract determined the timing of insemination, and deslorelin acetate was used to induce ovulation. Chilled semen insemination was performed using a single preovulatory dose delivered into the uterine body. Frozen semen was administered as 2 doses (pre- and post ovulation) using a deep uterine insemination technique. Pregnancy was detected ultrasonographically at 15 days post insemination. Conception rates were compared using a Chi-squared test. Insemination with frozen semen produced a significantly (P = 0.022) higher seasonal conception rate (82.0%) than that achieved with chilled semen (69.6%). Insemination with frozen semen can achieve conception rates equal to those with chilled semen, enabling the mare owner a greater selection of stallions.

OBJECTIVE To determine whether stored (cooled or frozen-thawed) jejunal segments can be used to obtain dependable leak pressure data after enterotomy closure. SAMPLE 36 jejunal segments from 3 juvenile pigs. PROCEDURES Jejunal segments were harvested from euthanized pigs and assigned to 1 of 3 treatment groups (n = 12 segments/group) as follows: fresh (used within 4 hours after collection), cooled (stored overnight at 5°C before use), and frozen-thawed (frozen at -12°C for 8 days and thawed at room temperature [23°C] for 1 hour before use). Jejunal segments were suspended and 2-cm enterotomy incisions were made on the antimesenteric border. Enterotomies were closed with a simple continuous suture pattern. Lactated Ringer solution was infused into each segment until failure at the suture line was detected. Leak pressure was measured by use of a digital transducer. RESULTS Mean ± SD leak pressure for fresh, cooled, and frozen-thawed segments was 68.3 ± 23.7 mm Hg, 55.3 ± 28.1 mm Hg, and 14.4 ± 14.8 mm Hg, respectively. Overall, there were no significant differences in mean leak pressure among pigs, but a significant difference in mean leak pressure was detected among treatment groups. Mean leak pressure was significantly lower for frozen-thawed segments than for fresh or cooled segments, but mean leak pressure did not differ significantly between fresh and cooled segments. CONCLUSIONS AND CLINICAL RELEVANCE Fresh porcine jejunal segments or segments cooled overnight may be used for determining intestinal leak pressure, but frozen-thawed segments should not be used.

AUTOMATIC ARCHITECTURAL STYLE RECOGNITION

Directory of Open Access Journals (Sweden)

M. Mathias

2012-09-01

Full Text Available Procedural modeling has proven to be a very valuable tool in the field of architecture. In the last few years, research has soared to automatically create procedural models from images. However, current algorithms for this process of inverse procedural modeling rely on the assumption that the building style is known. So far, the determination of the building style has remained a manual task. In this paper, we propose an algorithm which automates this process through classification of architectural styles from facade images. Our classifier first identifies the images containing buildings, then separates individual facades within an image and determines the building style. This information could then be used to initialize the building reconstruction process. We have trained our classifier to distinguish between several distinct architectural styles, namely Flemish Renaissance, Haussmannian and Neoclassical. Finally, we demonstrate our approach on various street-side images.

2011-09-01

The purpose of present study was to create and test a model that illustrates variables that influence the development of addiction susceptibility and determine how different styles of parenting may indirectly influence the addiction susceptibility of children through the mediators of attachment style and self-regulation. Using random cluster sampling, 508 adolescent high school boys and girls aged 14-19 years were enrolled. Data were analyzed using structural equations modeling (path analysis). The results showed that authoritative and permissive parenting styles were associated with secure attachment whereas authoritarian and neglectful parenting styles were associated with insecure attachment. Insecure attachment was associated with a low level of self-regulation whereas secure attachment was associated with a high level of self-regulation. We found that a low level of self-regulation increased the adolescent's addiction susceptibility whereas a high level of self-regulation decreased their addiction susceptibility. The findings of present study suggest the authoritative and permissive parenting styles as the most efficient styles and authoritarian and neglectful parenting styles as the most inefficient styles in terms of addiction susceptibility. Accordingly, efficient parenting style training to parents should be the main goal of drug demand reduction program.

Supervising away from home: clinical, cultural and professional challenges.

Science.gov (United States)

Abramovitch, Henry; Wiener, Jan

2017-02-01

This paper explores some challenges of supervising clinical work of trainees, known as 'routers', who live in countries with diverse cultural, social and political traditions, and the analysts who travel to supervise them. It is written as an evolving dialogue between the authors, who explore together the effects of their own culture of origin, and in particular the legacy and values of their own training institutes on the styles and models of analytic supervision. Their dialogue is framed around the meaning of home and experiences of homesickness for analysts working away from home in an interactive field of strangeness in countries where analytical psychology is a relatively new discipline. The authors outline the findings from their own qualitative survey, where other supervisors working abroad, and those they have supervised, describe their experiences and their encounters with difference. The dialogue ends with both authors discussing what they have learned about teaching and supervising abroad, the implications for more flexible use of Jungian concepts, and how such visits have changed their clinical practice in their home countries. © 2017, The Society of Analytical Psychology.

The aim of this study was to determine the chemical changes in muscle tissue of shortfin scad during storage at chilled (4 degree Celcius) and frozen (-18 degree Celcius) conditions for 18 days. The chemical changes were monitored every three days for Thiobarbituric acid (TBA), Peroxide value (PV), Total Volatile Base Nitrogen (TVBN) and Trimethylamine (TMA) content. Results show that there was a significant difference (p<0.05) in peroxide and TBA values between chilled and frozen shortfin scad starting from day 3. The highest PV values occured in chilled and frozen shortfin scad at day 12 (1.57 mEq/ kg and 1.13 mEq/ kg, respectively), and then decreased due to decomposition of hydroperoxides to secondary products such as aldehydes, alcohols and ketones. In contrast, TBA reached the highest values at day 15 for both chilled and frozen shortfin scad. For TVBN content, only the chilled sample shows significant increased (p<0.05) with storage time. The TVBN values declined significantly (p<0.05) for frozen shortfin scad. The TMA values for both chilled and frozen shortfin scad increased during storage. However, the TMA values increased at a faster rate in chilled compared to frozen shortfin scad. Based on the PV, TBA, TVBN and TMA values, chilled shortfin scad undergoes spoilage at a faster rate compared to the frozen shortfin scad. (author)

Coleopterofauna found on fresh and frozen rabbit carcasses in Curitiba, Paraná, Brazil

Directory of Open Access Journals (Sweden)

KM. Mise

Full Text Available Many arthropod species are associated with carrion and some of them can be used as forensic indicators in murder investigations to estimate the time of death. Different physical conditions of cadavers may influence the fauna and the importance of freezing and thawing is unknown. The present paper sought to survey the Coleoptera species encountered in frozen and fresh rabbit carcasses, at a forest in Curitiba, Brazil. Four rabbit carcasses, two of them fresh and the other frozen were used. The coleopterofauna was sampled daily, and analyzed using non-parametric tests. A total of 666 beetles were sampled, belonging to 28 species in 10 families. Most of the beetles captured were larvae of Oxelytrum spp. (433 which are known to be necrophagous. The two frozen carcasses accounted for most of the beetles (338 and 180 in comparison with the two fresh carcasses (103 and 45. The tests were based on the most abundant species. Oxelytrum spp. median differed significantly between carcasses (H = 12.47844; p = 0.0059. The two fresh carcasses differed significantly (U = 190.0; p = 0.00019, but there was no significant difference between the frozen carcasses (U = 336.0; p = 0.29755. The data indicate that the freezing process prevents certain species to colonize carcasses, in this case with the dominance of species of Oxelytrum. These data also indicate that careful attention is necessary before using frozen carcasses in forensic entomology studies.

ABSTRACT Objective: Surgical treatment options should be discussed in cases of frozen shoulder, which is usually treated in a conservative manner. In this study, we evaluated the efficacy of manipulation and arthroscopic release in cases of frozen shoulder which resisted conservative treatment. Methods: A total of 32 patients who underwent manipulation and arthroscopic capsular release in 34 shoulders were included in the study. The average follow-up period was 49.5 months (range: 24-90 months). No reason for onset could be found in 8 (25%) patients, who were classified as primary frozen shoulder; twenty-four (75%) patients were classified as secondary frozen shoulder due to underlying pathologies. The average pre-operative complaint period was 11 months (range: 3-24 months). After arthroscopic examination, manipulation was performed first, followed by arthroscopic capsular release. The range of motion in both shoulders was compared before the procedure and in the last follow-up visit. Constant and Oxford classifications were used to assess functional results, and the results were assessed statistically. Results: Patient values for passive elevation, abduction, adduction-external rotation, abduction-external rotation, and abduction-internal rotation increased in a statistically significant manner between the preoperative assessment and follow-up evaluation (p<0.01). The average change of 47.97±21.03 units observed in the patients’ values obtained in the control measurements against the pre-op Constant scores was determined to be statistically significant (p<0.01). According to the Oxford classification, 29 shoulders were sufficient. Conclusion: Successful results can be obtained with arthroscopic release performed after manipulation in patients with frozen shoulder resistant to conservative treatment.

2017-02-01

In pigs, acrosin activity in extended semen is correlated with reproductive performance and has recently been identified as a freezability marker. Reduced glutathione (GSH) is known to decrease sperm cryodamage and increase the reproductive performance of frozen-thawed boar spermatozoa. However, the effects of GSH on the acrosin activity of good and poor freezability ejaculates (GFE and PFE, respectively) is yet to be examined. The present study investigated how supplementing cryopreservation media with GSH affected acrosin activity in GFE and PFE, as well as the relationship between acrosin activity and reproductive performance in frozen-thawed boar spermatozoa. In addition, we examined whether the increase in fertility rates and litter sizes observed after the addition of 2mM GSH to cryopreservation extenders was related to acrosin activity. Supplementing freezing media with 2mM GSH partially counteracted the cryopreservation-related decrease in acrosin activity in GFE but not PFE. Acrosin activity was found to be significantly correlated with in vivo reproductive performance of frozen-thawed boar semen. In conclusion, the effects of adding GSH to freezing extenders on the acrosin activity of frozen-thawed boar spermatozoa rely on the intrinsic freezability of the ejaculate. Furthermore, the maintenance of proper acrosin activity could contribute to the increase in reproductive performance mediated by GSH.

2006-10-01

Experiments were conducted to evaluate in vitro fertilization (IVF) of in vitro matured (IVM) bitch oocytes using dog spermatozoa frozen in three different extenders. Sperm-rich fraction from eight ejaculates of five dogs was frozen in each one of three egg yolk Tris extenders with additional: (A) 1.4 g citric acid and 0.8 g glucose; (B) 0.7 g citric acid and 3.5 g glucose; or (C) 1.4 g citric acid and 0.8 g fructose (all with 5% glycerol in 100 mL milliQ water). Thawed sperm were co-incubated with IVM bitch oocytes for 6 h. Oocytes were fixed and evaluated under an epifluorescence microscope; penetrated oocytes were defined as those having sperm heads in the perivitelline space or in the oocyte cytoplasm. Higher penetration rates (P < 0.05) were obtained in oocytes cultured with spermatozoa frozen in extenders B and C than those frozen in extender A (33.1, 34.2 and 26.4%, respectively).

To evaluate the risk of ectopic pregnancy of embryo transfer. A retrospective cohort study on the incidence of ectopic pregnancy in fresh and frozen-thawed embryo transfer cycles from January 1 st , 2010, to January 1 st , 2015. Infertile women undergoing frozen-thawed transfer cycles or fresh transfer cycles. In-vitro fertilization, fresh embryo transfer, frozen-thawed embryo transfer, ectopic pregnancy. Ectopic pregnancy rate and clinical pregnancy rate. A total of 69 756 in vitro fertilization-embryo transfer cycles from 2010 to 2015 were analyzed, including 45 960 (65.9%) fresh and 23 796 (34.1%) frozen-thawed embryo transfer cycles. The clinical pregnancy rate per embryo transfer was slightly lower in fresh embryo transfer cycles compared with frozen-thawed embryo transfer cycles (40.8% vs 43.1%, P cycles, blastocyst transfer shows a significantly lower incidence of ectopic pregnancy (0.8% vs 1.8%, P = .002) in comparison with day 3 cleavage embryo transfer. The risk of ectopic pregnancy is lower in frozen-thawed embryo transfer cycles than fresh embryo transfer cycles, and blastocyst transfer could further decrease the ectopic pregnancy rate in frozen-thawed embryo transfer cycles.

Progress in quantitative X-ray microanalysis of frozen-hydrated bulk biological samples

International Nuclear Information System (INIS)

Marshall, A.T.

1988-01-01

The analysis of bulk frozen-hydrated biological samples has developed now to a level where practical application of the technique is possible. Provided the sample is carefully coated with a conductive metal, the development of a space charge capable of causing a significant distortion of the electron diffusion volume does not seem to occur, and analytical resolution can be conveniently held to approximately 2 micron (both depth and lateral resolution). Two valid quantitative methods are available, and two methods of determining dry weight fractions are also available. An area where further research could lead to improvement in analysis of frozen-hydrated bulk samples is in the investigation of fracturing methods. If fracture planes that were flat and reproducible could be easily obtained, some of the difficulties of analysing frozen-hydrated bulk samples would be considerably reduced

Parenting style is one of the most important and effective factors in training and growth of children and adolescents and the method that parents communicate with their children is an effective factor on family contact models. The aim of this study was to determine the impact of group training about parenting styles on maternal attitudes that were admitted to Isfahan Imam Ali (AS) health care center in 2013. This was an experimental study, which was conducted on a random sample of 25 mothers referred to this health care center. They were divided into two groups (experimental and control). The experimental group received five sessions of group training, and the control group received a booklet about parenting styles. The used tool in this study was the Bamerind Parenting Style Questionnaire that was completed by the mothers before and after the intervention and finally, their obtained scores were compared with each other. The results of the present study showed that the mean score of attitude toward easy-going style in test group was less than the control group after intervention (P = 0.045). The mean score of attitude toward authoritative style in the experimental group was less than control group after intervention (P = 0.037) and the mean score of attitude toward authoritative style in the experimental group was more than the control group after intervention (P = 0.011). Group training can be an appropriate method in changing maternal attitudes toward parenting styles.

2005-09-01

Irradiation of locally produced and imported food products was approved in the Kingdom of Saudi Arabia (KSA) in 2002. SureBeam Middle East (SME) has constructed the first food irradiation facility in Riyadh, KSA and will begin production irradiation in Q4 of 2005. In an effort to find efficient and cost effective means of irradiating frozen whole body chickens, SME has sponsored dose mapping studies using a 10 MeV dual electron beam processing system at the Electron Beam Food Research Facility at Texas A and M University (TAMU). Frozen chickens available to consumers in KSA range in size from nominal 600 grams to 1400 grams. Poultry processors typically provide retailers with equal weight birds packaged ten to a box (2 rows of 5 birds). Areal densities of the packages increase with the weight of the birds. For this study equivalent size birds were grown and processed by the Department of Poultry Science at TAMU and packaged in the same manner as in KSA. The goal of this investigation was to determine which size birds could be processed at a minimum dose of 2.5 kGy and not have the maximum dose exceed the level where negative sensory effects become noticeable. The minimum dose was chosen to reduce the population of any salmonella contamination by more than a factor of 1000. A description of the experimental set up and results of the dose mapping of frozen whole body chickens are reported herein, as are the results which indicate that electron beam processing of frozen chickens up to approximately 1000 grams can be readily accomplished and that processing of chickens up to 1400 grams may be possible Salmonella

Surgical Tips in Frozen Abdomen Management: Application of Coliseum Technique.

Science.gov (United States)

Kyriazanos, Ioannis D; Manatakis, Dimitrios K; Stamos, Nikolaos; Stoidis, Christos

2015-01-01

Wound dehiscence is a serious postoperative complication, with an incidence of 0.5-3% after primary closure of a laparotomy incision, and represents an acute mechanical failure of wound healing. Relatively recently the concept of "intentional open abdomen" was described and both clinical entities share common pathophysiological and clinical pathways ("postoperative open abdominal wall"). Although early reconstruction is the target, a significant proportion of patients will develop adhesions between abdominal viscera and the anterolateral abdominal wall, a condition widely recognized as "frozen abdomen," where delayed wound closure appears as the only realistic alternative. We report our experience with a patient who presented with frozen abdomen after wound dehiscence due to surgical site infection and application of the "Coliseum technique" for its definitive surgical management. This novel technique represents an innovative alternative to abdominal exploration, for cases of "malignant" frozen abdomen due to peritoneal carcinomatosis. Lifting the edges of the surgical wound upwards and suspending them under traction by threads from a retractor positioned above the abdomen facilitates approach to the peritoneal cavity, optimizes exposure of intra-abdominal organs, and prevents operative injury to the innervation and blood supply of abdominal wall musculature, a crucial step for subsequent hernia repair.

2009-01-01

To assess the relationship between life styles and eating habits with the overweight and obesity prevalence in a Spanish adult population. A population-based, cross-sectional study conducted on 2640 subjects older than 15 years, in Cádiz (Spain). Surveys were conducted in subjects' homes to obtain life styles, eating habits, and anthropometric data. Logistic regression has been used to study the association between the life style variables and overweight and obesity. Prevalence of overweight and obesity in Cadiz is 37% and 17%, respectively; higher in males and increases with age. BMI has an inverse relationship with educational level (PR = 2.3, 1.57-2.38). The highest levels of obesity are associated with daily alcohol consumption (PR = 1.39, 1.29-1.50), greater consumption of television,and sedentary pursuit (PR 1.5, 1.07-1.24). A lower prevalence of obesity is observed among those with active physical activity (10.9% vs 21.6%), with differences between sex. Following a slimming diet is more frequent in the obese and in women but dedicate more hours than men to passive activities. In men is greater the consumption of alcohol, high energy foods and snacks. Overweight and obesity is associated with the male sex (OR = 3.35 2.75-4.07), high consumption of alcohol (OR = 1.38 1.03-1.86) and watching television (OR = 1.52 1.11-2.07), and foods likes bread and cereals (OR = 1.47 1.13-1.91). Exercise activities is a protective factor (OR = 0.76 0.63-0.98). Life styles factors associated with overweight and obesity present different patterns in men and women and is necessary to understand them to identify areas for behavioural intervention in overweight and obesity patients.

BACKGROUND: The purpose of present study was to create and test a model that illustrates variables that influence the development of addiction susceptibility and determine how different styles of parenting may indirectly influence the addiction susceptibility of children through the mediators of attachment style and self-regulation. METHODS: Using random cluster sampling, 508 adolescent high school boys and girls aged 14-19 years were enrolled. Data were analyzed using structural equations modeling (path analysis). RESULTS: The results showed that authoritative and permissive parenting styles were associated with secure attachment whereas authoritarian and neglectful parenting styles were associated with insecure attachment. Insecure attachment was associated with a low level of self-regulation whereas secure attachment was associated with a high level of self-regulation. We found that a low level of self-regulation increased the adolescent's addiction susceptibility whereas a high level of self-regulation decreased their addiction susceptibility. CONCLUSIONS: The findings of present study suggest the authoritative and permissive parenting styles as the most efficient styles and authoritarian and neglectful parenting styles as the most inefficient styles in terms of addiction susceptibility. Accordingly, efficient parenting style training to parents should be the main goal of drug demand reduction program. PMID:22973379

Mathematical modeling and analysis of heat pipe start-up from the frozen state

International Nuclear Information System (INIS)

Jang, J.H.; Faghri, A.; Chang, W.S.; Mahefkey, E.T.

1989-08-01

The start-up process of a frozen heat pipe is described and a complete mathematical model for the start-up of the frozen heat pipe is developed based on the existing experimental data, which is simplified and solved numerically. The two-dimensional transient model for the wall and wick is coupled with the one-dimensional transient model for the vapor flow when vaporization and condensation occur at the interface. A parametric study is performed to examine the effect of the boundary specification at the surface of the outer wall on the successful start-up from the frozen state. For successful start-up, the boundary specification at the outer wall surface must melt the working substance in the condenser before dry-out takes place in the evaporator

Review: The procurement, storage and quality assurance of frozen blood and tissue biospecimens

Directory of Open Access Journals (Sweden)

2014-05-01

Full Text Available The preserved frozen biospecimens are ideal for evaluating the genome, transcriptome, and proteome. Here we present a current overview of experimental data regarding procurement, storage, and quality assurance that can informthe handling of frozen biospecimens. Degradation of frozen biospecimens can be affected by collecting methodology, premortem agonal changes and warm ischemic time during surgery.  Tissue storage at− 80 °C can preserve DNA and protein but RNA show degradation at 5 years, therefore storage at − 150 °C provides significant advantages.  Histologic quality assurance of tissue biospecimens is typically performed at the time of surgery but should also be conducted on the aliquot to be distributed because of tissue heterogeneity.Additional qualityassurance testing should be dictated by the anticipated downstream applications.

Uniaxial compression tests on diesel contaminated frozen silty soil specimens

International Nuclear Information System (INIS)

Chenaf, D.; Stampli, N.; Bathurst, R.; Chapuis, R.P.

1999-01-01

Results of a uniaxial, unconfined compression test on artificial diesel-contaminated and uncontaminated frozen silty soils are discussed. The testing program involved 59 specimens. The results show that for the same fluid content, diesel contamination reduced the strength of the frozen specimens by increasing the unfrozen water content. For example, in specimens containing 50 per cent diesel oil of the fluid content by weight the maximum strength was reduced by 95 per cent compared to the strength of an uncontaminated specimen. Diesel contamination was also shown to contribute to the slippage between soil particles by acting as a lubricant, thus accelerating the loss of compressive strength.13 refs., 18 figs

Education styles in a family versus life aims and values preferred by young people [Style wychowania w rodzinie a preferowane przez młodzież cele życiowe i wartości

Directory of Open Access Journals (Sweden)

2017-11-01

Full Text Available The socio-cultural, economic and political outlook changes visible in the contemporary world provoke deep transformations in all fields of life. The social conditions of life have been also deeply changing, often causing changes in views, expectations, behaviour patterns and life standards. In such a situation a young person experiences chaos and the feeling of being lost and looses the feeling of influence on their life. In an uncertain situation and with the feeling of being lost, and with difficulties connected with the adolescent crisis, young people need support from people being close to them. The special role plays family in that case. Family is the first social environment, integrally fulfilling different needs of a child and influencing his development in all areas of his life. All socialization processes developing in a family influence the shape of opinion and attitudes, patterns, traditions and accepted values. The correct one shapes proper, real and rational ideas of future life in children. The responsible parental function and shaping the proper social system in children is based on education styles that are very important for children. These styles are influenced mainly by parents, their views, educational aims, personal experience and patterns from their home. Education styles in a family decide mainly the level of psychological and social needs fulfillment, they shape the behaviour patterns in a family and can be internalized on different levels by imitation and identification, allowing for the adoption of values and standards. The article includes the source of research concerning the declared system of values and aims in life by the respondents. The results of behaviour styles in a family research have been discussed-all meanings, the frequency of particular education styles. The author also tried to show the connection between the family functioning and values chosen by children.

Radiation decontamination of frozen chicks

International Nuclear Information System (INIS)

Khan, M.; Akhtar, T.; Sattar, A.; Khan, I.

1992-07-01

In this report decontamination of frozen chicken has been discussed. The pathogenic bacteria present in poultry meats causes food infectious diseases. The spoilage microorganisms in poultry meat quickly render the meat unacceptable due to decomposition of the products resulting in off-odour and development of slime. Irradiation (2-5 kGy) and freezing has been found effective in eliminating various pathogens. These combination treatments were tested in local environment. The results indicated that radiation followed by freezing greatly protected quality of poultry meat during storage for 6 months. (A.B.)

2016-01-01

The present study examined the relationships between four personality traits, humor styles, and happiness. Replicating previous research, happiness was positively correlated with four personality traits: extraversion, locus of control, self-esteem, and optimism. Further, happiness positively related to self-enhancing and affiliative humor styles; it related negatively to self-defeating and aggressive humor styles. Thus, happy people habitually engage in positive uses of humor and avoid engaging in negative uses of humor in daily life. We also found support for our hypothesis. People high in extraversion, locus of control, self-esteem, and optimism are happier because they engage in positive humor in daily life. PMID:27547251

Fill and spill drives runoff connectivity over frozen ground

Science.gov (United States)

Coles, A. E.; McDonnell, J. J.

2018-03-01

Snowmelt-runoff processes on frozen ground are poorly understood at the hillslope scale. This is especially true for hillslopes on the northern Great Plains of North America where long periods of snow-covered frozen ground with very shallow slopes mask any spatial patterns and process controls on connectivity and hillslope runoff generation. This study examines a 4.66 ha (46,600 m2) hillslope on the northern Great Plains during the 2014 spring snowmelt season to explore hillslope runoff processes. Specifically, we explore the spatial patterns of runoff production source areas and examine how surface topography and patterns of snow cover, snow water equivalent, soil water content, and thawed layer depth - which we measured on a 10 m grid across our 46,600 m2 hillslope - affect melt water partitioning and runoff connectivity. A key question was whether or not the controls on connectivity are consistent with the fill and spill mechanism found in rain-dominated and unfrozen soil domains. The contrast between the slow infiltration rates into frozen soil and the relatively fast rates of snowmelt delivery to the soil surface resulted in water accumulation in small depressions under the snowpack. Consequently, infiltration was minimal over the 12 day melt period. Instead, nested filling of micro- and meso-depressions was followed by macro-scale, whole-slope spilling. This spilling occurred when large patches of ponded water exceeded the storage capacity behind downslope micro barriers in the surface topography, and flows from them coalesced to drive a rapid increase in runoff at the hillslope outlet. These observations of ponded water and flowpaths followed mapable fill and spill locations based on 2 m resolution digital topographic analysis. Interestingly, while surface topography is relatively unimportant under unfrozen conditions at our site because of low relief and high infiltrability, surface topography shows episodically critical importance for connectivity and

One of social problems which has affected our society and resulted in problems for different groups of people is drug abuse. This issue indicates a serious psychological, physical and social problem in community. Social skills have positive and successful influences in prevention of substance abuse. This includes the ability to explain events correctly and then appropriate decision making. This study compares decision making styles and attributional styles between addicted and non addicted men to recognize their role in addiction. In this study, 200 addicted and non addicted men were randomly selected. Decision-making style and attributional style questionnaires were used. Data analysis was performed by independent Student's t and Pearson correlation tests. The study population included 81 addicted and 90 non-addicted men. Addicted and non addicted men were significantly different in rational decision-making style (P rational decision making and optimistic attribution style (r = -0.305, P rational decision making and learned helplessness (r = 0.309, P rational in decision making and addicts that developed learned helplessness were less rational and did not have optimistic attribution style. These issues show that addiction institutions and therapists have to pay attention to cognitive factors for addiction prevention.

Robson, Shannon M; Crosby, Lori E; Stark, Lori J

2016-01-01

This study sought to understand barriers and facilitators for preparing and eating dinner at home in families who report eating dinner away from home ≥3 times per week. Cross-sectional, mixed methods (focus groups, questionnaires) study. Twenty-seven parents with a child 3-10 years-old who reported eating dinner away from home ≥3 times per week from a pediatric medical center in the Midwest participated. The key concepts analytic framework guided focus group analysis. Descriptive statistics were used to characterize parent demographics, anthropometrics, attitudes and confidence toward cooking, perceptions of dinner costs and portions, and parent and child dinners. Parents reported confidence in cooking a home prepared meal, but that eating away from home was reinforcing because it provided quality family time and diminished barriers such as picky eating and perceived costs. Home cooking was also hindered by early school lunch and after-school sports as children were not hungry or home at the typical dinner hour and parents did not want to cook after 8pm. Parents estimated preparing and eating a meal at home took significantly more time than driving and eating out (80.7 min vs. 30.3 min, p < 0.001). Parents significantly (F (3, 104) = 8.80, p < 0.001) overestimated the cost of home-prepared meals compared to take-out and frozen meals. Portion size was also overestimated for a protein serving. Findings are limited to predominantly married, female parents whom are highly educated and working. To reduce eating out, interventions should address family factors (e.g., time management, quality time) and child behavior (e.g., picky eating). Innovative interventions that include experiential cooking opportunities that incorporate time management, address picky eating and enthusiasm for cooking with education on decreasing costs may be particularly beneficial for middle-to high-income families.

Ruch, Willibald; Heintz, Sonja

2016-08-01

The Humor Styles Questionnaire (HSQ; Martin et al., 2003) is one of the most frequently used questionnaires in humor research and has been adapted to several languages. The HSQ measures four humor styles (affiliative, self-enhancing, aggressive, and self-defeating), which should be adaptive or potentially maladaptive to psychosocial well-being. The present study analyzes the internal consistency, factorial validity, and factorial invariance of the HSQ on the basis of several German-speaking samples combined (total N = 1,101). Separate analyses were conducted for gender (male/female), age groups (16-24, 25-35, >36 years old), and countries (Germany/Switzerland). Internal consistencies were good for the overall sample and the demographic subgroups (.80-.89), with lower values obtained for the aggressive scale (.66-.73). Principal components and confirmatory factor analyses mostly supported the four-factor structure of the HSQ. Weak factorial invariance was found across gender and age groups, while strong factorial invariance was supported across countries. Two subsamples also provided self-ratings on ten styles of humorous conduct (n = 344) and of eight comic styles (n = 285). The four HSQ scales showed small to large correlations to the styles of humorous conduct (-.54 to .65) and small to medium correlations to the comic styles (-.27 to .42). The HSQ shared on average 27.5-35.0% of the variance with the styles of humorous conduct and 13.0-15.0% of the variance with the comic styles. Thus-despite similar labels-these styles of humorous conduct and comic styles differed from the HSQ humor styles.

Little is known about mother-child feeding interactions and how this is associated with food intake and linear growth. To characterize mother-child feeding styles and investigate their associations with accepted mouthful and linear growth in west Gojam, rural Ethiopia. Two, in-home, meal observations of children aged 12-23 months (n = 100) were video-taped. The number of mouthful accepted was counted and the caregiver/child feeding styles were coded into positive/negative categories of self-feeding, responsive-feeding, active-feeding, social-behavior and distraction. Data on socio-demographic characteristics, child feeding practices, perception about child's overall appetite, and strategies adopted to overcome food refusal were collected through questionnaire-based interviews. Child and mothers' anthropometric measurements were also taken. Stunting was highly prevalent (48%) and the number of mouthful accepted was very low. Offering breastmilk and threatening to harm were the main strategies adopted to overcome food refusal. Although all forms of feeding style were present, active positive feeding style was dominant (90%) and was positively associated with mouthful accepted. Talking with non-feeding partner (64%), and domestic animals (24%) surrounding the feeding place were common distractions of feeding. Feeding was mostly terminated by caregivers (75%), often prematurely. Overall, caregivers of stunted children had poorer complementary- and breast-feeding practices and were less responsive to child's hunger and satiation cues (P responsive feeding behaviors were associated with child's number of mouthful accepted (r = 0.27; P = 0.007) and stunting (r = 0.4; P feeding style and stunting. Nutrition interventions that reinforce messages of optimal infant and young child feeding and integrate the promotion of responsive feeding behaviors are needed. Copyright © 2017 Elsevier Ltd.

To investigate whether fruit and vegetable (F&V) intake in 11-year-olds, and social-environmental correlates of F&V intake such as parental modelling and encouragement, family food rules and home availability, differ according to general parenting styles in Belgium, The Netherlands, Portugal and Spain. Cross-sectional study. Primary schools in four countries. Pupils and one of their parents completed questionnaires to measure F&V intake, related social-environmental correlates and general parenting styles. The sample size was 4555 (49.3 % boys); 1180 for Belgium, 883 for The Netherlands, 1515 for Portugal and 977 for Spain. Parenting styles were divided into authoritative, authoritarian, indulgent and neglectful. No differences were found in F&V intake across parenting styles and only very few significant differences in social-environmental correlates. The authoritarian (more parental encouragement and more demands to eat fruit) and the authoritative (more availability of fruit and vegetables) parenting styles resulted in more favourable correlates. Despite earlier studies suggesting that general parenting styles are associated with health behaviours in children, the present study suggests that this association is weak to non-existent for F&V intakes in four different European countries.

2014-10-01

The aim of this study was to evaluate the efficiency of different media in the in vitro culture of bovine preantral follicles that were used either fresh or following slow freezing treatment. Frozen and fresh noncultured or cultured ovarian fragments were processed for histological, viability, and cell proliferation analyses. For cryopreservation, a solution containing 1.5 M ethylene glycol was frozen in a programmable biological freezer. After thawing, a portion of the samples was destined for frozen controls. The remainder were cultured in vitro for 5 days in three media: α-MEM, McCoy, or M199. Samples from these culture media were collected on days 1 and 5 for quantification of reactive oxygen species (ROS) and for hormonal assays. In fresh-cultured tissues, the percentage of morphologically normal follicles was significantly higher when cultured in M199 compared to that in the other media. In frozen-cultured tissues, McCoy medium was significantly superior to the other media, and was the only treatment that helped in maintaining the viability similar to fresh and frozen controls. Upon quantification of the nucleolus organizer region, we observed greater proliferation of granulosa cells in the frozen-cultured tissues with McCoy medium, and lesser proliferation in fresh-cultured tissues only with α-MEM. In frozen-cultured tissues, ROS levels were highest at day 1 and progressively reduced during culture, independent of the media used. In conclusion, under the conditions used in this study, the M199 and McCoy media are recommended for the culture of follicles derived from fresh and frozen ovarian tissues, respectively.

Humor and creative life styles.

Science.gov (United States)

Richman, J

2001-01-01

This paper is based upon the writings of William James in the late 19th century, and Alfred Adler and Sigmund Freud in the 20th, enriched by the contributions of later personality and role theorists. The self is defined as the unique organization of each person; a style is the self in action. Different life styles and their components are expressed in different situations. I posit that humor and positive thinking, combined with meaning and purpose, are vital components of all constructive life styles. The knowledge of life styles cuts through diagnostic labels to reveal our universal humanity. It can be fruitfully applied to patients and nonpatients alike and, I found, for the self-understanding of therapist. The clinical application of life styles is illustrated through numerous vignettes.

Conclusion: Although the sample size of the studied population was small but our study results support the previous data and suggest that in early stages and low grade tumors, gross examination and frozen section diagnosis are conveniently predictive of lymph node metastasis. These data might be useful for prediction of tumor invasion using frozen section and gross examination in low grade tumors and early stages and for doing complete surgical staging and lymph node sampling. However the im-portance of surgical staging always must be considered in patients who need systemat-ic lymphadenectomy. In overall these data might help to come up with new guidelines for surgical risk assessment in endometrial cancer.

QUALIY PARAMETERS AND SHELF LIFE OF GAME MEAT DURING FROZEN STORAGE

Directory of Open Access Journals (Sweden)

M. Spaziani

2011-01-01

Full Text Available This study examined the effect of the duration of frozen storage at –20°C on the game meat quality parameters, namely the pH, colour, thawing and cooking losses. The oxidative stability of game meat was evaluated by the production of thiobarbituric acid reactive substances (TBARS. Frozen storage duration did not extensively influence either the quality properties, or the oxidative stability of game meat. Therefore, it was hypothesized that the higher amount of a- tocopherol in the muscles of game compared to pellet-fed animals could be mainly responsible for the lower lipid oxidation and longer shelf life.

1999-03-01

Ikaite, calcium carbonate hexahydrate, has by means of X-ray diffraction analyses of frozen samples been identified as the mineral component of the white spots formed in the shell of frozen shrimp during storage. When the shrimp thaw and the shell material is dried and kept at room temperature, ikaite rapidly transforms into a mixture of anhydrous calcium carbonate forms. X-ray diffraction analyses and Raman spectra of synthetic ikaite as well as the dehydration product confirm the assignments, and the rate constant for dehydration is approximately 7 x 10(-)(4) s(-)(1) at ambient temperature. Differential scanning calorimetry showed that dehydration of synthetic ikaite is an entropy-driven, athermal process and confirms that a single first-order reaction is rate-determining. Ikaite is found to be stable in aqueous solution at temperatures below 5 degrees C and in the shell of frozen shrimps but decomposes on thawing to form anhydrous calcium carbonates.

Fatigue effect in ferroelectric crystals: Growth of the frozen domains

Shur, V. Ya.; Akhmatkhanov, A. R.; Baturin, I. S.

2012-06-01

The model of the fatigue effect during cyclic switching caused by growth of the frozen domain area with charged domain walls has been proposed. It was claimed on the basis of the previous experimental results that for switching in increasing field the frozen domain area started to grow at the given sub-threshold field value and stopped at the threshold field. The influence of the shape and frequency of the field pulses used for cyclic switching has been considered. The uniaxial ferroelectric stoichiometric lithium tantalate single crystals produced by vapor transport equilibration with record low value of coercive field have been chosen as a model material for experimental verification of the model. The formation of the charged domain walls as a result of cyclic switching has been revealed by analysis of the domain images obtained by optical and Raman confocal microscopy. It has been shown that the fatigue degree is equal to the fraction of the frozen domain area. The experimental dependence of the switched charge on the cycle number has been successfully fitted by modified Kolmogorov-Avrami formula. The experimentally observed frequency independence of fatigue profile for rectangular pulses and frequency dependence for triangular pulses has been explained by proposed model.

To determine whether frozen-thawed blastocyst transfer pregnancy rates (PR) are lower in African-American compared with white women. Retrospective review of frozen blastocyst cycles. University-based assisted reproductive technology (ART) program. All patients who underwent a frozen blastocyst transfer between 2003 and 2008. None. Live birth rate. One hundred sixty-nine patients underwent transfer of a frozen-thawed blastocyst. African-American women had a higher incidence of leiomyoma (40% vs. 10%) and tubal and uterine factor infertility. There was no difference in the live birth rate for African-American patients (28.0%) compared with white patients (30.2%). Of the patients who underwent a frozen-thawed blastocyst transfer, 58% (n=98) had their fresh, autologous IVF cycle, which produced the cryopreserved blastocyst, at Walter Reed Medical Center. A higher peak serum E2 level was noted in African-American patients (5,355 pg/mL) compared with white patients (4,541 pg/mL). During the fresh cycle, the live birth rates between African-American and white patients were significantly different at 16.7% versus 39.7%, respectively. Live birth rates after frozen blastocyst transfer are not different between African-American and white women despite a fourfold higher incidence of leiomyomas in African-American women.

Impact of water extractable arabinoxylan from rye bran on frozen steamed bread dough quality was investigated in terms of the bread characteristics, ice crystallization, yeast activity as well as the gluten molecular weight distribution and glutenin macropolymer content in the present study. Results showed that water extractable arabinoxylan significantly improved bread characteristics during the 60-day frozen storage. Less water was crystallized in the water extractable arabinoxylan dough during storage, which could explain the alleviated yeast activity loss. For all the frozen dough samples, more soluble high molecular weight (Mw ≈ 91,000-688,000) and low molecular weight (Mw ≈ 91,000-16,000) proteins were derived from glutenin macropolymer depolymerization. Nevertheless, water extractable arabinoxylan dough developed higher glutenin macropolymer content with lowered level of soluble low molecular weight proteins throughout the storage. This study suggested water extractable arabinoxylan from rye bran had great potential to be served as an effective frozen steamed bread dough improver. Copyright © 2016 Elsevier Ltd.

2006-01-01

We examine to what extent the popularity of an investment style can be attributed to style investing. The style investing hypothesis predicts that assets in the same style show strong comovement with respect to their underlying fundamentals and that reclassifying assets into a new style raises its correlation with that style. We test this prediction by studying how comovement varies with proxies of popularity. We use different kinds of data, such as data on stocks, mutual funds, IPO?s and fin...

Altered explorative strategies and reactive coping style in the FSL rat model of depression

Directory of Open Access Journals (Sweden)

Salvatore eMagara

2015-04-01

Full Text Available Modeling depression in animals is based on the observation of behaviors interpreted as analogue to human symptoms. Typical tests used in experimental depression research are designed to evoke an either-or outcome. It is known that explorative and coping strategies are relevant for depression, however these aspects are generally not considered in animal behavioral testing. Here we investigate the Flinders Sensitive Line (FSL, a rat model of depression, compared to the Sprague-Dawley (SD rat in three independent tests where the animals are allowed to express a more extensive behavioral repertoire. The multivariate concentric square field™ (MCSF and the novel cage tests evoke exploratory behaviors in a novel environment and the home cage change test evokes social behaviors in the re-establishment of a social hierarchy. In the MCSF test, FSL rats exhibited less exploratory drive and more risk-assessment behavior compared to SD rats. When re-exposed to the arena, FSL, but not SD rats, increased their exploratory behavior compared to the first trial and displayed risk-assessment behavior to the same extent as SD rats. Thus, the behavior of FSL rats was more similar to that of SDs when the rats were familiar with the arena. In the novel cage test FSL rats exhibited a reactive coping style, consistent with the reduced exploration observed in the MCSF. Reactive coping is associated with less aggressive behavior. Accordingly, FSL rats displayed less aggressive behavior in the home cage change test. Taken together, our data show that FSL rats express altered explorative behavior and reactive coping style. Reduced interest is a core symptom of depression, and individuals with a reactive coping style are more vulnerable to the disease. Our results support the use of FSL rats as an animal model of depression and increase our understanding of the FSL rat beyond the behavioral dimensions targeted by the traditional depression-related tests.

This study examined the associations between parenting styles, teacher interactional styles, and children's reading and spelling skills. The sample consisted of 864 Finnish-speaking children and their parents (864 mothers, 864 fathers) and teachers (N=123). Children's risk for reading disabilities and reader status were assessed in kindergarten. Children were also tested on reading and spelling skills in Grades 1 and 2. Parenting styles and teacher interactional styles were measured using parents' and teachers' self-reports in Grade 1. First, the results indicated that both an authoritative parenting style and authoritative teacher interactional style positively predicted children's spelling skill development. Second, authoritative parenting was particularly beneficial for the spelling skill development of children who were at risk for reading disabilities. Third, authoritative teaching promoted spelling skill development particularly among children who were nonreaders in kindergarten but had no risk for reading disabilities. Finally, some evidence was found that authoritative teaching could compensate for the negative impact of nonauthoritative parenting on reading development among kindergarten nonreaders.

Researchers are engaged in finding the precursors for innovation. Drawing on Kirton's Adaption-Innovation (KAI) Inventory, we explicitly test Kirton's central premise that cognitive styles differentiate between preferences for producing ideas in a certain way. We argue that the generation of either a magnitude or original ideas is governed by different underlying cognitive styles. In a study with 191 individuals, we find that the cognitive style originality associates with ideational fluency ...

Full Text Available Analysis of preference of educational styles is highly relevant, since it points out both to the more general underlying value orientations and the expected or desired effects of socialization process. This paper deals with the level of acceptance and factors of valuing the autonomous and conformist educational styles among Serbian citizens, operationalised through estimation of importance of qualities that children should learn at home. Based on the three waves of World Values Survey, the analysis of data from Serbia was performed in longitudinal perspective in the period from 1996 to 2006 (total N=3700, as well as in comparative perspective, when the data obtained in Serbia were compared with the data collected in the European countries that participated in the last, fifth wave of World Values Survey (total N=23941. The results indicate that, in the observed period, on the average two thirds of citizens (64% are characterized by preference of autonomous educational style, while respondents' education and population size of settlement figure as the most important factors of preference. However, according to the level of acceptance of autonomy, Serbia is placed 16th out of 21 analyzed European countries, and therefore, in comparative perspective, valuing of autonomy in the country is on a relatively low level. The results imply that by a non-selective encouragement of autonomy in all students, by cooperation with parents or a more general promotion of knowledge, school may play an important role in this process.

Full Text Available BACKGROUND: Physiological changes and chronic diseases arising during aging process increase risk of accident of the elderly, especially the elderly living alone at their homes. Home accidents are the most commonly health problem in the elderly. This study was carried out to describe home safety of the elderly living in a city or rural area using a home safety checklist. MEDHODS: 512 living in Turkey (330 in city; 182 in rural area were evaluated via face-to-face interview using a home safety checklist during a period between December and March in 2007. In addition to sociodemographics, a questionnaire including home characteristics and life style of participants was applied. To describe home safety level, Home Safety Checklist was used. RESULTS: 51.8% of the participants living in a city and 42.8% living in rural area were aged 65-69 years. Of the participants living in a city, 59.4% were living with their partners (61.5% of the participants living in rural area. While 63.9% of the participants living in a city reported that they had a private room in their homes, 53.8% of the participants living in rural area reported that they had a private room in their homes. 2.1% of participants living in a city had an excellent home safety score. Percentage for participants living in rural area was 0.5. CONCLUSION: The results obtained from this study show that majority of houses of the elderly living in Turkey were unsafe and hazardous. Therefore, health providers and architects should work together to prevent home accidents. [TAF Prev Med Bull 2008; 7(4.000: 297-300

The per cent viability of Bacillus popilliae after lyophilization of liquid nitrogen frozen cells was determined. Lyophilization of 9- to 12-hr cells which had been suspended in 5% sodium glutamate plus 0.5% gum tragacanth, frozen in liquid nitrogen vapor, and dried 4 to 5 hr with the ampoules exposed to room temperature resulted in survival of 64.6% of the original cells. After storage of these lyophilized preparations for 6 months at room temperature, 10.5% of the original cells were still viable. PMID:6031431

Nurse managers who can observe their own behaviour and its effects on employees can adjust to a better leadership style. The intention of this study was to explore nurses' and supervisors' perceptions of nurse managers' leadership styles. Open-ended interviews were conducted with 11 nurses and 10 superiors. The data were analysed by content analysis. In the study, six leadership styles were identified: visionary, coaching, affiliate, democratic, commanding, and isolating. Job satisfaction and commitment as well as operation and development work, cooperation, and organizational climate in the work unit were the factors, affected by leadership styles. The nurse managers should consider their leadership style from the point of view of employees, situation factors, and goals of the organization. Leadership styles where employees are seen in a participatory role have become more common.

2010-04-01

This study evaluated the effect of freezing method (FM) (air blast freezer, freezing tunnel, or nitrogen chamber) and frozen storage duration (FSD) (1, 3, or 6 months) on the instrumental measurements of quality of thawed lamb, aged for a total of 72 h, throughout a 10-d display period, compared to the quality of fresh meat. pH, colour, lipid oxidation, thawing, and cooking losses in Longissimus thoracis and lumborum muscle, were determined following standard methods. FM affected yellowness, FSD redness and thawing losses, and both affected oxidation (increased as freezing rate decreased and/or as storage duration increased). When compared with fresh meat, the main differences appeared on oxidation (where a significant interaction between treatment (3FM x 3FSD + fresh meat) with display duration was detected), and on total losses (thaw + cook losses). Oxidation was lower in fresh meat, but values were not significantly different from those stored frozen for 1 month. Fresh meat had smaller total losses than did thawed meat, but losses were not significantly different from meat frozen in the freezing tunnel and stored frozen for 1 month. Display duration had a greater effect on instrumental quality parameters than did FM or FSD. pH, b*, and oxidation increased, and L* and a* decreased with an increase in the number of days on display. In conclusion, neither freezing method nor frozen storage up to 6 months influenced extensively the properties of lamb when instrumental measurements of quality were measured in meat that had been displayed for 1d after thawing. The small deterioration shown in this study should not give consumers concerns about frozen meat. 2009 Elsevier Ltd. All rights reserved.

Monitoring recharge in areas of seasonally frozen ground in the Columbia Plateau and Snake River Plain, Idaho, Oregon, and Washington

Science.gov (United States)

Mastin, Mark; Josberger, Edward

2014-01-01

Seasonally frozen ground occurs over approximately one‑third of the contiguous United States, causing increased winter runoff. Frozen ground generally rejects potential groundwater recharge. Nearly all recharge from precipitation in semi-arid regions such as the Columbia Plateau and the Snake River Plain in Idaho, Oregon, and Washington, occurs between October and March, when precipitation is most abundant and seasonally frozen ground is commonplace. The temporal and spatial distribution of frozen ground is expected to change as the climate warms. It is difficult to predict the distribution of frozen ground, however, because of the complex ways ground freezes and the way that snow cover thermally insulates soil, by keeping it frozen longer than it would be if it was not snow covered or, more commonly, keeping the soil thawed during freezing weather. A combination of satellite remote sensing and ground truth measurements was used with some success to investigate seasonally frozen ground at local to regional scales. The frozen-ground/snow-cover algorithm from the National Snow and Ice Data Center, combined with the 21-year record of passive microwave observations from the Special Sensor Microwave Imager onboard a Defense Meteorological Satellite Program satellite, provided a unique time series of frozen ground. Periodically repeating this methodology and analyzing for trends can be a means to monitor possible regional changes to frozen ground that could occur with a warming climate. The Precipitation-Runoff Modeling System watershed model constructed for the upper Crab Creek Basin in the Columbia Plateau and Reynolds Creek basin on the eastern side of the Snake River Plain simulated recharge and frozen ground for several future climate scenarios. Frozen ground was simulated with the Continuous Frozen Ground Index, which is influenced by air temperature and snow cover. Model simulation results showed a decreased occurrence of frozen ground that coincided with

Do emergency medicine residents and faculty have similar learning styles when assessed with the Kolb learning style assessment tool?

Fredette, Jenna; O'Brien, Corinne; Poole, Christy; Nomura, Jason

2015-04-01

Experiential learning theory and the Kolb Learning Style Inventory (Kolb LSI) have influenced educators worldwide for decades. Knowledge of learning styles can create efficient learning environments, increase information retention, and improve learner satisfaction. Learning styles have been examined in medicine previously, but not specifically with Emergency Medicine (EM) residents and attendings. Using the Kolb LSI, the learning styles of Emergency Medicine residents and attendings were assessed. The findings showed that the majority of EM residents and attendings shared the accommodating learning style. This result was different than prior studies that found the majority of medical professionals had a converging learning style and other studies that found attendings often have different learning styles than residents. The issue of learning styles among emergency medical residents and attendings is important because learning style knowledge may have an impact on how a residency program structures curriculum and how EM residents are successfully, efficiently, and creatively educated.

Convergent validity of two decision making style measures

Directory of Open Access Journals (Sweden)

Berisha, Gentrit

2018-04-01

Full Text Available Decision making research has witnessed a growing number of studies on individual differences and decision making styles, yet the lack of comprehensive frameworks and widely accepted measures has hindered research for a long time. There is an ongoing debate on whether individuals’ styles dynamically change across time and situations according to circumstances. Furthermore, it is an open question whether these styles are mutually exclusive. Decision style measures seek to determine one’s dominant style as well as less used styles. To our knowledge this is the first study of the convergent validity of two widely used decision making style measures: The Decision Style Inventory (DSI and the General Decision Making Style (GDMS. The direction and strength of correlation between directive, analytical, conceptual and behavioral styles as measured by DSI and rational, intuitive, dependent, avoidant and spontaneous styles as measured by GDMS have been tested. Results of the current study are compared with previous studies that have used one or both of the instruments. Correlations between styles are consistent with findings from other studies using one of the decision style measures, but the strength of correlations indicates that there is no convergent validity between DSI and GDMS.

Full Text Available In this study, oxidative stability of frozen chicken breast and thigh muscle after application of feed mixtures enriched by phytogenic additives was investigated. The 150 pieces one-day-old chicks of Cobb 500 hybrid combination were divided into three groups: C - control group, G1 – experimental group with addition 1000 mg kg-1 Biostrong 510 + FortiBac and G2 – experimental group with addition 1000 mg kg-1 Agolin Acid.  The broiler chickens were fed during 42 days by ad libitum. Samples of chicken breast and thigh muscle were analysed in the 1st day and after 1st, 2nd, 3rd, 4th, 5th and 6th month of frozen storage at -18 °C. During testing period we recorded positive influence of phytogenic additives on oxidative stability of chicken meat in experimental groups (G1, G2. After 6th month of frozen storage, we found higher malondialdehyde (MDA values and lower oxidative stability of breast muscle in control group (0.167 mg.kg-1 compared to experimental groups G1 (0.149 mg.kg-1 and G2 (0.145 mg.kg-1. Similar tendency of oxidative changes as in the breast muscle was recorded in the thigh muscle. At the end of frozen storage MDA average values of thigh muscle were higher in control group (0.181 mg.kg-1 compared to experimental groups (G1 - 0.163 mg.kg-1 and G2 - 0.160 mg.kg-1.  Based on the obtained results we can stated, that phytogenic additives applied in chicken nutrition had positive influence of, namely on oxidation stability of fatty substances.

Rearing Styles, Parents' Attachment Mental State,and Children's Social Abilities: The Link to Peer Acceptance

Grazia Attili

2011-01-01

Full Text Available This paper examines the discriminant effect of mothers' and fathers' attachment working models, the quality of their relationships in everyday settings, and children's social abilities on children's peer acceptance. Participants were thirty-four 7–9 year olds, their mothers, and fathers. Interactions were observed at home and coded on global measures of positive, negative, controlling, disconfirming, correcting behaviors, and neutral conversation. Parents' IWM were assessed by the AAI. Children's peer acceptance and behavioral orientations as a measure of a child's social competence at school were assessed by sociometric techniques. By using both traditional statistical analyses and a multidimensional scaling approach (MDS, in terms of “similarity structure analysis (SSA” and the “external variables as points technique,” it emerged that children's lack of success among peers associated with social behaviors which were linked to parents' rejecting/neglecting and directive interactive styles, mainly to negative, disconfirming, and a few positive interactions. These parenting styles were significantly affected by adults' insecure IWM.

Nijhof, Karin S; Engels, Rutger C M E

2007-10-01

The present study examined the role of parenting styles in the experience and expression of homesickness, and the way of coping with the feelings involved. Using a sample of 670 first year college and university students, aged 16 to 25, we tested three hypotheses: (1) authoritarian, permissive as well as uninvolved parenting are associated with the experience of homesickness, contrary to students with authoritative parents who are less likely to have feelings of homesickness; (2) students with authoritarian, permissive or uninvolved parents show their homesickness by internalizing and externalizing problems; and (3) students raised by authoritative or permissive parents use more effective coping strategies to deal with homesickness. Results indicated that students raised by authoritative and permissive parents experienced more homesickness with stronger feelings of homesickness than students raised by authoritarian or uninvolved parents. However, they hardly express homesickness by internalizing or externalizing problems when they use effective ways of coping, namely support-seeking and/or problem-solving. Students with parents endorsing an authoritarian or uninvolved parenting style, on the other hand, showed more internalizing and externalizing problems in reaction to feelings of homesickness. They also use less effective coping strategies. The results revealed the importance of a loving and accepting home environment for the development and expression of homesickness, as well as the importance of the way in which students learn to cope with their problems.

2003-01-01

The purpose of this retrospective review was to evaluate the effectiveness of a hydraulic distention technique (hydroplasty) combined with a therapy program for treatment of idiopathic frozen shoulder. Over a two-year period, 60 patients with idiopathic frozen shoulder were identified as having undergone the hydroplasty procedure and therapy protocol at the authors' hand center. Distention of the glenohumeral joint was achieved by an injection of a 10-mL combination of bupivacaine (Marcaine), lidocaine (Xylocaine), and corticosteroid followed by injection of 30 mL of chilled sterile normal saline. Therapy was initiated immediately after the surgeon had completed the hydroplasty. The mean active range of motion improvement was as follows: flexion 28 degrees, abduction 42 degrees, internal rotation 22 degrees, and external rotation 26 degrees. There was no significant difference in outcomes between diabetics and nondiabetics or subjects with symptoms less than six months' duration compared with subjects with symptom duration greater than six months. At discharge, only two (3%) of the subjects reported persistent pain during sleep. The hydroplasty procedure combined with a therapy program is a successful treatment for idiopathic frozen shoulder.

Strategic Style in Pared-Down Poker

Science.gov (United States)

Burns, Kevin

This chapter deals with the manner of making diagnoses and decisions, called strategic style, in a gambling game called Pared-down Poker. The approach treats style as a mental mode in which choices are constrained by expected utilities. The focus is on two classes of utility, i.e., money and effort, and how cognitive styles compare to normative strategies in optimizing these utilities. The insights are applied to real-world concerns like managing the war against terror networks and assessing the risks of system failures. After "Introducing the Interactions" involved in playing poker, the contents are arranged in four sections, as follows. "Underpinnings of Utility" outlines four classes of utility and highlights the differences between them: economic utility (money), ergonomic utility (effort), informatic utility (knowledge), and aesthetic utility (pleasure). "Inference and Investment" dissects the cognitive challenges of playing poker and relates them to real-world situations of business and war, where the key tasks are inference (of cards in poker, or strength in war) and investment (of chips in poker, or force in war) to maximize expected utility. "Strategies and Styles" presents normative (optimal) approaches to inference and investment, and compares them to cognitive heuristics by which people play poker--focusing on Bayesian methods and how they differ from human styles. The normative strategy is then pitted against cognitive styles in head-to-head tournaments, and tournaments are also held between different styles. The results show that style is ergonomically efficient and economically effective, i.e., style is smart. "Applying the Analysis" explores how style spaces, of the sort used to model individual behavior in Pared-down Poker, might also be applied to real-world problems where organizations evolve in terror networks and accidents arise from system failures.

Leadership = Communication? The Relations of Leaders' Communication Styles with Leadership Styles, Knowledge Sharing and Leadership Outcomes.

de Vries, Reinout E; Bakker-Pieper, Angelique; Oostenveld, Wyneke

2010-09-01

PURPOSE: The purpose of this study was to investigate the relations between leaders' communication styles and charismatic leadership, human-oriented leadership (leader's consideration), task-oriented leadership (leader's initiating structure), and leadership outcomes. METHODOLOGY: A survey was conducted among 279 employees of a governmental organization. The following six main communication styles were operationalized: verbal aggressiveness, expressiveness, preciseness, assuredness, supportiveness, and argumentativeness. Regression analyses were employed to test three main hypotheses. FINDINGS: In line with expectations, the study showed that charismatic and human-oriented leadership are mainly communicative, while task-oriented leadership is significantly less communicative. The communication styles were strongly and differentially related to knowledge sharing behaviors, perceived leader performance, satisfaction with the leader, and subordinate's team commitment. Multiple regression analyses showed that the leadership styles mediated the relations between the communication styles and leadership outcomes. However, leader's preciseness explained variance in perceived leader performance and satisfaction with the leader above and beyond the leadership style variables. IMPLICATIONS: This study offers potentially invaluable input for leadership training programs by showing the importance of leader's supportiveness, assuredness, and preciseness when communicating with subordinates. ORIGINALITY/VALUE: Although one of the core elements of leadership is interpersonal communication, this study is one of the first to use a comprehensive communication styles instrument in the study of leadership.

Frozen soil barrier technology. Innovative technology summary report

International Nuclear Information System (INIS)

1995-04-01

The technology of using refrigeration to freeze soils has been employed in large-scale engineering projects for a number of years. This technology bonds soils to give load-bearing strength during construction; to seal tunnels, mine shafts, and other subsurface structures against flooding from groundwater; and to stabilize soils during excavation. Examples of modern applications include several large subway, highway, and water supply tunnels. Ground freezing to form subsurface frozen soil barriers is an innovative technology designed to contain hazardous and radioactive contaminants in soils and groundwater. Frozen soil barriers that provide complete containment (open-quotes Vclose quotesconfiguration) are formed by drilling and installing refrigerant piping (on 8-ft centers) horizontally at approximately 45 degrees angles for sides and vertically for ends and then recirculating an environmentally safe refrigerant solution through the piping to freeze the soil porewater. Freeze plants are used to keep the containment structure at subfreezing temperatures. A full-scale containment structure was demonstrated from May 12 to October 10, 1994, at a nonhazardous site on SEG property on Gallaher Road, Oak Ridge, Tennessee

2015-03-01

The effect of final baking in convection oven (FBC), microwave oven (FBM), and microwave oven with susceptor packaging material (FBMS) on partially baked (PB) frozen gluten-free bread characteristics was investigated. Specific volume and crust color of loaves were measured at day 0. Bread moisture, water activity, and crumb and crust texture (at 15, 45, and 90 min after baking) were analyzed at day 0 and after 28 d of frozen storage (-18 °C). Volatile compounds from breads baked in convection oven or microwave oven with susceptor packaging material were also evaluated. Bread finally baked in convection oven or in microwave oven with susceptor packaging increased crust browning. Crumb and roll hardness increased with time after final baking (measured at 15, 45, 90 min) and after 28 d of frozen storage. Bread finally baked in microwave oven was the hardest, due to high water losses. At day 0, bread finally baked in convection oven had softer crumb than bread finally baked in microwave oven with susceptor packaging but, after 28 d of frozen storage, there were no differences between them. Moreover, FBC and FBMS rendered gluten-free breads that could not be distinguished in a triangular test and had the same volatile compounds profile. In conclusion, FBMS could be an alternative to FBC. © 2015 Institute of Food Technologists®

Hard tissue decalcification can cause variation in the constituent protein characteristics. This paper describes a method of preparating of frozen mouse head sections so as to clearly observe the nature of the constituent proteins. Frozen sections of various green fluorescent protein (GFP) transgenic mouse heads were prepared using the film method developed by Kawamoto and Shimizu. This method made specimen dissection without decalcification possible, wherein GFP was clearly observed in an undamaged state. Conversely, using the same method with decalcification made GFP observation in the transgenic mouse head difficult. This new method is suitable for observing GFP marked cells, enabling us to follow the transplanted GFP marked cells within frozen head sections

Full Text Available Severe discharge of sewage and industrial effluents into the Persian Gulf leads to the deposition of various types of heavy metals, especially lead and mercury, in the muscles of fish. Total mercury and methylmercury contents were determined in the edible parts (muscle tissue, fillet of two different most popular frozen fish species from the Persian Gulf to ascertain whether the concentrations exceeded the maximum level fixed by the European Commission or not. During the period from October 2015 to June 2016, a total of 150 frozen fish packaged samples were randomly collected from the recognized supermarkets in Tehran province, Iran. The mercury (Hg concentration of samples was determined by atomic absorption spectrophotometer using a mercuric hydride system (MHS 10 and also by direct mercury analyzer (DMA. High concentration of total Hg was found in a Carcharhinus dussumie brand (0.91 ± 0.12 μg/g while the lowest level was detected in Pomadasys furcatus (0.29 ± 0.02 μg/g. In current study the mean concentrations of Mercury in all studied frozen fish samples were 0.79 ± 0.11 µg/g that means Hg levels were above 0.5 μg/g, which is the maximum standard level recommended by Joint FAO/WHO/Expert Committee on Food Additives (JECFA. In 13% of Pomadasys and in 47.2 % of Carcharhinus fish samples total mercury concentrations exceeded the maximum level fixed by the European Commission. All samples had also mean Hg concentrations that exceeded EPA's established safety level of 0.3 μg/g.

Urine provides a convenient non-invasive alternative to blood sampling for measurement of certain hormones. Urinary luteinizing hormone (LH) measurements have been used for endocrinology research and anti-doping testing. However, the commercially available LH immunoassays are developed and validated for human blood samples but not urine so that LH assays intended for use with urine samples need thorough validation. Therefore, the present study evaluated the measurement of urinary LH immunoreactivity using previously validated immunofluorometric (IF) and immunochemiluminometric (ICL) LH assays after prolonged frozen storage. LH was measured in serial urine samples following administration of a single injection of one of two doses of recombinant human chorionic hormone (rhCG) with assays run at the end of study (2008) and again after four years of frozen (-20 °C) storage where samples were stored without adding preservatives. The ICL assay showed quantitatively reproducible LH measurements after prolonged -20 °C storage. However, the IF immunoassay gave consistently lower LH levels relative to ICL (2008) with a further proportionate reduction after four years of sample storage (2012). Yet, both the assays displayed similar patterns of the time-course of urine LH measurement both before and after four years of frozen storage. In conclusion, we found that both immunoassays are suitable for urinary LH measurements with ICL assay being more robust for quantitative urinary LH measurement such as for anti-doping purposes, whereas the IF could be applicable for research studies where urine LH levels are compared within-study but not in absolute terms.

The aim of the study was to analyse the parental bonding profiles in patients with eating disorders (ED), as well as the relationship among the different styles of parenting and some psychological and psychopathological variables. In addition, the association between the perceived parental bonding and different coping strategies was analysed. Perception of parenting styles was analysed in a sample of 70 ED patients. The Parental Bonding Instrument, Self-Esteem Scale of Rosenberg, Coping Strategies Inventory, State-Trait Anxiety Inventory, Beck Depression Inventory and Eating Disorders Inventory-2 were used. Kruskal-Wallis test (comparisons), Spearman correlation coefficients (association among different variables) and χ(2)-test (parental bonding profiles differences) were applied. The stereotyped style among ED patients is low care-high control during the first 16 years, and the same can be said about current styles of the mothers. Between 8.6% and 12.9% of the patients perceive their parents' styles as neglectful. The neglectful parenting is the style mainly involved in the specific ED symptoms as drive for thinness, body dissatisfaction and bulimia. In order to achieve a better balanced parents' role during the treatment, it would be necessary to improve the role of the mothers as caregivers, decreasing their role mainly based on the overprotection. © 2011 Blackwell Publishing.

How do people with different attachment styles balance work and family? A personality perspective on work-family linkage.

Science.gov (United States)

Sumer, H C; Knight, P A

2001-08-01

This study explored whether different models of work-family relationship were possible for individuals with different attachment styles. A mail survey was conducted using employees (N = 481) at a midwestern university in the United States. Results suggested that (a) individuals with a preoccupied attachment pattern were more likely to experience negative spillover from the family/home to the work domain than those with a secure or dismissing style, (b) securely attached individuals experienced positive spillover in both work and family domains more than those in the other groups, and (c) preoccupied individuals were much less likely to use a segmentation strategy than the other 3 attachment groups. However, when the conventional job satisfaction life satisfaction relationship was examined, the data provided unique support for the spillover model. Implications of the findings for both attachment and work family relationship literatures are discussed.

A ‘frozen volume’ transition model and working mechanism for the shape memory effect in amorphous polymers

Lu, Haibao; Wang, Xiaodong; Yao, Yongtao; Qing Fu, Yong

2018-06-01

Phenomenological models based on frozen volume parameters could well predict shape recovery behavior of shape memory polymers (SMPs), but the physical meaning of using the frozen volume parameters to describe thermomechanical properties has not been well-established. In this study, the fundamental working mechanisms of the shape memory effect (SME) in amorphous SMPs, whose temperature-dependent viscoelastic behavior follows the Eyring equation, have been established with the considerations of both internal stress and its resulted frozen volume. The stress-strain constitutive relation was initially modeled to quantitatively describe effects of internal stresses at the macromolecular scale based on the transient network theory. A phenomenological ‘frozen volume’ model was then established to characterize the macromolecule structure and SME of amorphous SMPs based on a two-site stress-relaxation model. Effects of the internal stress, frozen volume and strain rate on shape memory behavior and thermomechanical properties of the SMP were investigated. Finally, the simulation results were compared with the experimental results reported in the literature, and good agreements between the theoretical and experimental results were achieved. The novelty and key differences of our newly proposed model with respect to the previous reports are (1). The ‘frozen volume’ in our study is caused by the internal stress and governed by the two-site model theory, thus has a good physical meaning. (2). The model can be applied to characterize and predict both the thermal and thermomechanical behaviors of SMPs based on the constitutive relationship with internal stress parameters. It is expected to provide a power tool to investigate the thermomechanical behavior of the SMPs, of which both the macromolecular structure characteristics and SME could be predicted using this ‘frozen volume’ model.

Frozen: The Potential and Pitfalls of Ground-Penetrating Radar for Archaeology in the Alaskan Arctic

Directory of Open Access Journals (Sweden)

Thomas M. Urban

2016-12-01

Full Text Available Ground-penetrating radar (GPR offers many advantages for assessing archaeological potential in frozen and partially frozen contexts in high latitude and alpine regions. These settings pose several challenges for GPR, including extreme velocity changes at the interface of frozen and active layers, cryogenic patterns resulting in anomalies that can easily be mistaken for cultural features, and the difficulty in accessing sites and deploying equipment in remote settings. In this study we discuss some of these challenges while highlighting the potential for this method by describing recent successful investigations with GPR in the region. We draw on cases from Bering Land Bridge National Preserve, Cape Krusenstern National Monument, Kobuk Valley National Park, and Gates of the Arctic National Park and Preserve. The sites required small aircraft accessibility with light equipment loads and minimal personnel. The substrates we investigate include coastal saturated active layer over permafrost, interior well-drained active layer over permafrost, a frozen thermo-karst lake, and an alpine ice patch. These examples demonstrate that GPR is effective at mapping semi-subterranean house remains in several contexts, including houses with no surface manifestation. GPR is also shown to be effective at mapping anomalies from the skeletal remains of a late Pleistocene mammoth frozen in ice. The potential for using GPR in ice and snow patch archaeology, an area of increasing interest with global environmental change exposing new material each year, is also demonstrated.

Frozen ground has an important role in regional hydrological cycles and ecosystems, particularly on the Qinghai-Tibetan Plateau (QTP), which is characterized by high elevations and a dry climate. This study modified a distributed, physically based hydrological model and applied it to simulate long-term (1971-2013) changes in frozen ground its the effects on hydrology in the upper Heihe basin, northeastern QTP. The model was validated against data obtained from multiple ground-based observations. Based on model simulations, we analyzed spatio-temporal changes in frozen soils and their effects on hydrology. Our results show that the area with permafrost shrank by 8.8 % (approximately 500 km2), predominantly in areas with elevations between 3500 and 3900 m. The maximum depth of seasonally frozen ground decreased at a rate of approximately 0.032 m decade-1, and the active layer thickness over the permafrost increased by approximately 0.043 m decade-1. Runoff increased significantly during the cold season (November-March) due to an increase in liquid soil moisture caused by rising soil temperatures. Areas in which permafrost changed into seasonally frozen ground at high elevations showed especially large increases in runoff. Annual runoff increased due to increased precipitation, the base flow increased due to changes in frozen soils, and the actual evapotranspiration increased significantly due to increased precipitation and soil warming. The groundwater storage showed an increasing trend, indicating that a reduction in permafrost extent enhanced the groundwater recharge.

Acrosin release and acrosin activity during incubation in capacitating media using fresh and frozen-thawed dog sperm

Mónica de los Reyes

2011-01-01

Full Text Available We evaluated the effect of time and temperature on acrosin release from the acrosomal cap and the activity of this enzyme during in vitro capacitation in fresh and frozen/thawed dog sperm. Sperm-rich fractions of six ejaculates from three dogs were processed as fresh and frozen samples. Each sperm sample was incubated in canine capacitation medium (CCM for 0, 1, 2 and 3 h at 20°C and at 37°C. After incubation, the samples were assessed by the indirect immunofluorescent staining technique. The probability of having unlabeled sperm (PUS, indicating acrosin loss, was modelled by a binomial distribution using logistic regression. There was a linear relationship between PUS and time at both temperatures (p<0.001; however, a major percentage of unlabeled sperm was observed in frozen/thawed samples soon after incubation, indicating that the release of acrosin was affected by capacitation time, mainly in frozen samples. Temperature influenced acrosin release only in cryopreserved sperm (p<0.05. Acrosin activity was measured by digestion halos on slides coated with gelatin-substrate film during each time period; a significant increase in the number of large halos was observed in fresh samples throughout the experiment, whereas frozen/thawed sperm showed a decreased rate of halo diameters during culture. Thus, there appears to differences between fresh and frozen dog sperm in terms of acrosin release and the level of acrosin activity in the course of in vitro capacitation.

Petroleum hydrocarbon remediation in frozen soil using a meat and bonemeal biochar plus fertilizer.

Science.gov (United States)

Karppinen, Erin M; Stewart, Katherine J; Farrell, Richard E; Siciliano, Steven D

2017-04-01

Petroleum hydrocarbon (PHC) degradation slows significantly during the winter which substantially increases the time it takes to remediate soil in Arctic landfarms. The aim of this laboratory trial was to assess the potential of a meat and bonemeal (MBM) biochar to stimulate PHC degradation in contaminated soil collected from Iqaluit, Canada. Over 90 days, 3% (w/w) MBM biochar significantly increased F3- (equivalent nC 16 -C 34 ) PHC degradation rate constants (k) in frozen soils when compared to the fertilizer (urea and monoammonium phosphate) control. Taking into consideration extensive variability within treatments and negative k values, this difference may not reflect significant remediation. Decreasing C 17 /Pr and C 18 /Ph ratios in the frozen soil suggest that this reduction is a result of microbial degradation rather than volatilization. Amendment type and application rate affected the immediate abiotic losses of F2 and F3-PHC in sterile soils, with the greatest losses occurring in compost-amended treatments in the first 24 h. In frozen soils, MBM biochar was found to increase liquid water content (θ liquid ) but not nutrient supply rates. Under frozen but not thawed conditions, genes for aromatic (C2,3O and nahAc) but not aliphatic (alkB) PHC degradation increased over time in both biochar-amended and control treatments but total viable PHC-degrading populations only increased in biochar-amended soils. Based on these results, it is possible that PHC degradation in biochar-amended soils is active and even enhanced under frozen conditions, but further investigation is required.

1991-01-01

The authors have sometimes experienced cases of frozen gait without any other manifestations of parkinsonisms in the elderly, so we examined these cases using MR imaging and SPECT imaging. The group with frozen gait (4 cases, aged 78 to 82 years) which failed to respond to L-dopa therapy, had no limb-kinetic apraxia or frontal signs, but did exhibit 'kinesie paradoxale'. The clinical symptoms of case 4 were consistent with so-called 'pure akinesia'. CT findings in this group failed to elucidate the pathogenesis of frozen gait. MR imaging of all of the cases except for the case of pure akinesia (case 4) revealed a high signal intensity areas in subcortical lesions (especially the frontal area). Case 4 had only a few spotty high-signal intensity areas. We then compared 6 cases which have the same lesions (on MRI) as cases 1∼3 without frozen gait in cases 1∼3 using 123 I-IMP SPECT. Relatively low accumulation of radionuclide in the frontal area was observed in these cases. Case 4 had a slightly low perfusion area in the frontal lobe. However in the patient treated with L-threo-DOPS, accumulation of radionuclide in the frontal area increased slightly after L-threo-DOPS therapy. It appears that one of the reasons for frozen gait in the elderly is incomplete infarct of the subcortical white matter with a low perfusion area in the frontal cortex. Furthermore, in some cases of frozen gait it is difficult to distinguish between cases with white matter disorders and cases of pure akinesia on the basis of clinical symptons and CT alone. (author)

Today’s high performance green homes are reaching previously unheard of levels of airtightness and are using new materials, technologies and strategies, whose impacts on Indoor Air Quality (IAQ) cannot be fully anticipated from prior studies. This research study used pollutant measurements, home inspections, diagnostic testing and occupant surveys to assess IAQ in 24 new or deeply retrofitted homes designed to be high performance green buildings in California. Although the mechanically vented homes were six times as airtight as non-mechanically ventilated homes (medians of 1.1 and 6.1 ACH₅₀, n=11 and n=8, respectively), their use of mechanical ventilation systems and possibly window operation meant their median air exchange rates were almost the same (0.30 versus 0.32 hr^-1, n=8 and n=8, respectively). Pollutant levels were also similar in vented and unvented homes. In addition, these similarities were achieved despite numerous observed faults in complex mechanical ventilation systems. More rigorous commissioning is still recommended. Cooking exhaust systems were used inconsistently and several suffered from design flaws. Failure to follow best practices led to IAQ problems in some cases. Ambient nitrogen dioxide standards were exceeded or nearly so in four homes that either used gas ranges with standing pilots, or in Passive House-style homes that used gas cooking burners without venting range hoods. Homes without active particle filtration had particle count concentrations approximately double those in homes with enhanced filtration. The majority of homes reported using low-emitting materials; consistent with this, formaldehyde levels were approximately half those in conventional, new CA homes built before 2008. Emissions of ultrafine particles (with diameters <100 nm) were dramatically lower on induction electric cooktops, compared with either gas or resistance electric models. These results indicate that high performance homes can achieve

The variability observed in nanoparticle (NP) dispersions can affect the reliability of the results obtained in short-term tests, and mainly in long-term experiments. In addition, obtaining a good dispersion is time-consuming and acts as a bottleneck in the development of high-throughput screening methodologies. The freezing of different aliquots from a stock dispersion would overcome such limitations, but no studies have explored the impact of freezing thawing the samples on the physico-chemical and biological properties of the nanomaterial (NM). This work aims to compare fresh-prepared and frozen MWCNT, ZnO-, Ag-, TiO 2- and CeO 2 -NP dispersions, used as models. NP characterization (size and morphology by TEM), hydrodynamic size and zeta potential were performed. Viability comparisons were determined in BEAS-2B cells. Cellular NP uptake and induced ROS production was assessed by TEM and flow cytometry, respectively. The obtained results show no important differences between frozen and fresh NP in their physico-chemical characteristics or their biological effects. This study is the first to demonstrate that there is no scientific evidence to dismiss the use of frozen NP, opening the door to the development of short- and long-term experiments with higher consistency, accuracy and reproducibility in a much shorter time and using a simplified procedure.

Frozen Soil Barrier. Subsurface Contaminants Focus Area. OST Reference No. 51

International Nuclear Information System (INIS)

1999-01-01

Problem: Hazardous and radioactive materials have historically been disposed of at the surface during operations at Department of Energy facilities. These contaminants have entered the subsurface, contaminating soils and groundwater resources. Remediation of these groundwater plumes using the baseline technology of pump and treat is expensive and takes a long time to complete. Containment of these groundwater plumes can be alternative or an addition to the remediation activities. Standard containment technologies include slurry walls, sheet piling, and grouting. These are permanent structures that once installed are difficult to remove. How It Works: Frozen Soil Barrier technology provides a containment alternative, with the key difference being that the barrier can be easily removed after a period of time, such as after the remediation or removal of the source is completed. Frozen Soil Barrier technology can be used to isolate and control the migration of underground radioactive or other hazardous contaminants subject to transport by groundwater flow. Frozen Soil Barrier technology consists of a series of subsurface heat transfer devices, known as thermoprobes, which are installed around a contaminant source and function to freeze the soil pore water. The barrier can easily be maintained in place until remediation or removal of the contaminants is complete, at which time the barrier is allowed to thaw.

Parenting style and parental support and modeling of physical activity and healthy dietary intake have been linked to youth weight status, although findings have been inconsistent across studies. Furthermore, little is known about how these factors co-occur, and the influence of the coexistence of these factors on adolescents' weight. This article examines the relationship between the co-occurrence of various parenting characteristics and adolescents' weight status. Data are from Project EAT (eating among teens), a population-based study of 4,746 diverse adolescents. Theoretical and latent class groupings of parenting styles and parenting practices were created. Regression analyses examined the relationship between the created variables and adolescents' BMI. Having an authoritarian mother was associated with higher BMI in sons. The co-occurrence of an authoritarian mother and neglectful father was associated with higher BMI for sons. Daughters' whose fathers did not model or encourage healthy behaviors reported higher BMIs. The co-occurrence of neither parent modeling healthy behaviors was associated with higher BMIs for sons, and incongruent parental modeling and encouraging of healthy behaviors was associated with higher BMIs in daughters. Although, further research into the complex dynamics of the home environment is needed, findings indicate that authoritarian parenting style is associated with higher adolescent weight status and incongruent parenting styles and practices between mothers and fathers are associated with higher adolescent weight status.

The growth and fertility of a female calf obtained from a frozen-thawed bovine oocyte was assessed. The birth weight of the calf was lower than the mean birth weight of calves from in vitro fertilized embryos (IVF-controls) and calves obtained by artificial insemination (AI-controls). The growth rate of the calf up to 6 months was slower than that of the IVF-controls, but similar to that of the AI-controls. When the calf developed into a heifer (200 kg), she was inseminated with frozen semen and 280 days later delivered a male calf. The chromosoms of this cow were normal. These findings suggest that the growth and fertility of the calf derived from the frozen oocyte are normal.

Formalin-fixed, paraffin-embedded (FFPE) pathology specimens represent a potentially vast resource for transcriptomic-based biomarker discovery. We present here a comparison of results from a whole transcriptome RNA-Seq analysis of RNA extracted from fresh frozen and FFPE livers. The samples were derived from rats exposed to aflatoxin B1 (AFB1 ) and a corresponding set of control animals. Principal components analysis indicated that samples were separated in the two groups representing presence or absence of chemical exposure, both in fresh frozen and FFPE sample types. Sixty-five percent of the differentially expressed transcripts (AFB1 vs. controls) in fresh frozen samples were also differentially expressed in FFPE samples (overlap significance: P < 0.0001). Genomic signature and gene set analysis of AFB1 differentially expressed transcript lists indicated highly similar results between fresh frozen and FFPE at the level of chemogenomic signatures (i.e., single chemical/dose/duration elicited transcriptomic signatures), mechanistic and pathology signatures, biological processes, canonical pathways and transcription factor networks. Overall, our results suggest that similar hypotheses about the biological mechanism of toxicity would be formulated from fresh frozen and FFPE samples. These results indicate that phenotypically anchored archival specimens represent a potentially informative resource for signature-based biomarker discovery and mechanistic characterization of toxicity.

Relevant to the study of epileptogenesis is learning processing, given the pivotal role that neuroplasticity assumes in both mechanisms. Recently, evoked potential analyses showed a link between analytic cognitive style and altered neural excitability in both migraine and healthy subjects, regardless of cognitive impairment or psychological disorders. In this study we evaluated analytic/global and visual/auditory perceptual dimensions of cognitive style in patients with epilepsy. Twenty-five cryptogenic temporal lobe epilepsy (TLE) patients matched with 25 idiopathic generalized epilepsy (IGE) sufferers and 25 healthy volunteers were recruited and participated in three cognitive style tests: "Sternberg-Wagner Self-Assessment Inventory", the C. Cornoldi test series called AMOS, and the Mariani Learning style Questionnaire. Our results demonstrate a significant association between analytic cognitive style and both IGE and TLE and respectively a predominant auditory and visual analytic style (ANOVA: p values <0,0001). These findings should encourage further research to investigate information processing style and its neurophysiological correlates in epilepsy. Copyright © 2017 Elsevier Inc. All rights reserved.

Management styles and motivation.

Science.gov (United States)

Shearer, Dana Ann

2012-01-01

According to a review of the current literature, common managerial styles are transformational, transactional, and laissez-faire. When managers expand their leadership skills to improve the staff's morale, they must use a combination of transformational leadership behaviors and transactional contingent rewards to maximize their effectiveness on employees. A motivation theory such as Herzberg and Maslow enhances employees' motivation, morale, and satisfaction. Being able to motivate, empower, and influence staff improves satisfaction and retention levels among the team. A manager's leadership style influences motivation, morale, and retention in staff. Leaders are influenced by their educational development and the organizational culture. Organizational culture has an impact on a manager's style, which is forwarded to their followers.

Frozen pre-stuffed turkeys from 12 week females were conductively cooked at 163°C to an 85°C internal breast end-point. Bread cubes having 50% added water filled crop and body cavity to 20% of weight the turkeys were then frozen. Each of 4 treatments employed 7 carcasses: one was thawed to +5°C with repetitions at -5, -15, and -25°C enabling a regression analysis. Time to attain breast end-point was 44 min when the starting temperature was +5°C, which increased to 63 min at -5°C, and 69 min at -25°C (P cooking was initiated at +5°C and increased to 84°C as the starting temperatures fell to -25°C (P cooking, thereafter decreasing to 59 and 60°C when at -5 and -15°C, respectively, before returning to 65°C for the -25°C case (P cooking was initiated at +5°C. This increased to 22.6% at -25°C (P cooking averaged 23.7% however, the percentage of fat in the drip increased from 51.1% when using +5°C, to 57.2% with carcasses at -25°C (P cooked after thawing, particularly for crop (59.4% using +5°C vs. 55.8% frozen, P cooking from the frozen state, while cavity stuffing consistently failed to attain a safe temperature. © 2015 Poultry Science Association Inc.
