Relationship between work–family conflict and a sense of coherence among Japanese registered nurses
Authors: TAKEUCHI Tomoko , YAMAZAKI Yoshihiko 
Published: August 2010

AbstractAim:  Work–family conflict (WFC) refers to the conflict that arises between a person's work and family life. Previous studies have reported workload, job demands, and irregular working shifts as related to the WFC among nurses and have clarified that WFC is a predictor of job satisfaction, morale, and turnover intention. Very few studies have investigated WFC among Japanese nurses and no study has taken into consideration the sense of coherence (SOC) that helps nurses to cope with stress. The present study aimed to determine the relationship between WFC and SOC and to clarify how WFC and a SOC influence the mental and physical health of nurses in order to suggest ways of establishing work environments that enable nurses to achieve a balance between their work and family life.Methods:  A self‐report questionnaire survey of 388 Japanese female nurses was conducted. The data from 138 nurses who were a mother and/or wife were analyzed.Results:  Work–family conflict was significantly related to the SOC. It had a larger impact on the physical and mental health of nurses than their work and family characteristics. The SOC also had a major influence on the physical and mental health of nurses, while having a buffering effect on WFC with respect to depression.Conclusions:  Our findings underscore the importance of taking organizational steps to create work environments that contribute to an enhanced SOC in order to reduce the WFC among nurses.

Abstract
2M1938+4603 (KIC 9472174) displays a spectacular light curve dominated by a strong reflection effect and rather shallow, grazing eclipses. The orbital period is 0.126 d, the second longest period yet found for an eclipsing sdB+dM, but still close to the minimum 0.1-d period among such systems. The phase-folded Kepler light curve was used to detrend the orbital effects from the data set. The amplitude spectrum of the residual light curve reveals a rich collection of pulsation peaks spanning frequencies from ∼50 to 4500 μHz. The presence of a complex pulsation spectrum in both the p- and g-mode regions has never before been reported in a compact pulsator.
Eclipsing sdB+dM stars are very rare, with only seven systems known and only one with a pulsating primary. Pulsating stars in eclipsing binaries are especially important since they permit masses derived from seismological model fits to be cross-checked with orbital mass constraints. We present a first analysis of this star based on the Kepler 9.7-d commissioning light curve and extensive ground-based photometry and spectroscopy that allow us to set useful bounds on the system parameters. We derive a radial-velocity amplitude K1 = 65.7 ± 0.6 km s −1, inclination angle , and find that the masses of the components are M1 = 0.48 ± 0.03 M⊙ and M2 = 0.12 ± 0.01 M⊙.

Abstract
We report the discovery of a very cool, isolated brown dwarf, UGPS 0722−05, with the United Kingdom Infrared Telescope Deep Sky Survey (UKIDSS) Galactic Plane Survey. The near-infrared spectrum displays deeper H2O and CH4 troughs than the coolest known T dwarfs and an unidentified absorption feature at 1.275 μm. We provisionally classify the object as a T10 dwarf but note that it may in future come to be regarded as the first example of a new spectral type. The distance is measured by trigonometric parallax as d = 4.1+0.6−0.5 pc, making it the closest known isolated brown dwarf. With the aid of Spitzer/Infrared Array Camera (IRAC) we measure H − [4.5] = 4.71. It is the coolest brown dwarf presently known – the only known T dwarf that is redder in H−[4.5] is the peculiar T7.5 dwarf SDSS J1416+13B, which is thought to be warmer and more luminous than UGPS 0722−05. Our measurement of the luminosity, aided by Gemini/T-ReCS N-band photometry, is L = 9.2 ± 3.1 × 10−7 L⊙. Using a comparison with well-studied T8.5 and T9 dwarfs we deduce Teff = 520 ± 40 K. This is supported by predictions of the Saumon & Marley models. With apparent magnitude J = 16.52, UGPS 0722−05 is the brightest of the ∼90 T dwarfs discovered by UKIDSS so far. It offers opportunities for future study via high-resolution near-infrared spectroscopy and spectroscopy in the thermal infrared.

AbstractThe purpose of this study was to evaluate the accuracy of electronic apex locators Digital Signal Processing (DSP) and ProPex, for root canal length determination in primary teeth. Fifteen primary molars (a total of 34 root canals) were divided into two groups: Group I – without physiological resorption (n = 16); and Group II – with physiological resorption (n = 18). The length of each canal was measured by introducing a file until its tip was visible and then it was retracted 1 mm. For electronic measurement, the devices were set to 1 mm short of the apical resorption. The data were analysed statistically using the intraclass correlation coefficient (ICC). Results showed that the ICC was high for both electronic apex locators in all situations – with (ICC: DSP = 0.82 and Propex = 0.89) or without resorption (ICC: DSP = 0.92 and Propex = 0.90). Both apex locators were extremely accurate in determining the working length in primary teeth, both with or without physiological resorption.
Water demand management: implementation principles and indicative case studies
Authors: Kampragou Eleni , Lekkas Demetris F. , Assimacopoulos Dionysis 
Published: August 2010

AbstractCurrent practices for the efficient use and management of water resources are based on the conjunctive application of water supply and demand measures. Even though options for the augmentation of water supply are widely analysed and assessed, water demand management remains an open field for study, as it is highly dependent on the socio‐economic features of a region and has a site‐specific character. This paper summarizes the guiding principles of demand management and presents some successful application examples of demand management measures from regions that cover a wide range of socioeconomic and environmental conditions in an effort to identify the critical factors for the efficient planning and implementation of demand management plans.
Arsenic removal from aqueous solutions by adsorption on magnetite nanoparticles
Authors: Chowdhury Saidur Rahman , Yanful Ernest K. 
Published: August 2010

AbstractMagnetite nanoparticles were used to treat arsenic‐contaminated water. Because of their large surface area, these particles have an affinity for heavy metals by adsorbing them from a liquid phase. The results of the study showed that the maximum arsenic adsorption occurred at pH 2, with a value of approximately 3.70 mg/g for both As(III) and As(V) when the initial concentration of both arsenic species was maintained at 2 mg/L. The study showed that, apart from pH, the removal of arsenic from contaminated water also depends on the contact time, the initial concentration of arsenic, the phosphate concentration in the water and the adsorbent concentration. The results suggest that arsenic adsorption involved the formation of weak arsenic–iron oxide complexes at the magnetite surface. At a fixed adsorbent (magnetite nanoparticles) concentration of 0.4 g/L, percent arsenic removal decreased with increasing phosphate concentration. Magnetite nanoparticles removed <50% of arsenic from water containing >6 mg/L phosphate. In this case, an optimum design for achieving high arsenic removal by magnetite nanoparticles may be required.

International Journal of Older People Nursing7, 105–116 doi: 10.1111/j.1748‐3743.2010.00243.xAim and objectives.  To describe and compare the individualised care perceptions of older orthopaedic patients’ and patients of working age.Background.  Age has been found to influence perceptions of care and although individualised care is highlighted in the literature, it is seldom studied from an older person’s perspective.Design.  Descriptive and comparative.Methods.  Data were collected using the Individualised Care Scale from orthopaedic patients (n = 420, response rate 84%). The participants were divided into two groups: those 65 and over (n = 149) and those under 65 and working (n = 271). Data analysis used descriptive and inferential statistics.Results.  Patients expressed a desire for individualised care, and gave relatively good evaluations about the perceived support for their individuality and the realisation of individualised care. Differences in the perceptions of individualised care were found between, but not within, the two groups. The older patients were more positive in their evaluations.Conclusions.  There is a need for programmes of individualised care that are age‐adjusted.Relevance to clinical practice.  As the older population rises worldwide individualised care becomes more important in the care of older people. These findings provide baseline data for the development of individualised nursing care from the patients’ perspective.

Please cite this paper as: McKinley et al. (2010) The pathogenesis of H3N8 canine influenza virus in chickens, turkeys and ducks. Influenza and Other Respiratory Viruses 4(6), 353–356.Background  Canine influenza virus (CIV) of the H3N8 subtype has emerged in dog populations throughout the United States where it has become endemic in kennels and animal shelters in some regions. It has not previously been determined whether the canine‐adapted H3N8 influenza virus can be transmitted to chickens, turkeys or ducks which are economically important animals that are susceptible to type A influenza virus from numerous species.Methods  Four‐week‐old specific pathogen–free (SPF) chickens, 3‐week‐old SPF turkeys and 2‐week‐old commercial Pekin ducks were inoculated with 105·2 50% tissue culture infectious doses of CIV per bird by the intra‐choanal route. The birds were observed daily, and at 2 and 4 days post‐inoculation (DPI), two inoculated birds and one sham‐inoculated control bird were euthanized and necropsied to evaluate gross lesions and to collect tissues for microscopic examination. Cloacal and oral swabs were collected at 2, 4 and 7 DPI to evaluate virus shed by real‐time RT‐PCR (rRT‐PCR). Two weeks post‐infection, sera were collected from all remaining birds for type A influenza antibody detection by hemagglutination inhibition assay.Results  Clinical signs and gross lesions were not observed in any of the birds of any species nor did any seroconvert. Oral and Cloacal swab material was negative for virus by rRT‐PCR.Conclusions  Chickens, turkeys and Pekin ducks are not susceptible to infection with CIV by simulated respiratory exposure route with the dose administered.

Please cite this paper as: Vahlenkamp et al. (2010) Systemic influenza virus H5N1 infection in cats after gastrointestinal exposure. Influenza and Other Respiratory Viruses 4(6), 379–386.Background  Highly pathogenic avian influenza virus (HPAIV) H5N1 infections in felids have been reported in several countries. Feeding on infected birds has been suggested as potential source of infection.Objectives  The study aimed to verify gastrointestinal infection as possible portal of entry for HPAIV H5N1 in cats.Methods  Four cats were infected oculo‐nasopharyngeally with 106 50% egg infectious dose (EID50) of HPAIV H5N1 A/cat/Germany/R606/2006. Two cats were infected intravenously with 106 EID50 and two cats were inoculated orally with 107 EID50 HPAIV embedded in gelatine capsules to mimic gastrointestinal exposure and to avoid virus contact to oropharyngeal or respiratory tissues. Cats were monitored for 6 days by physical examination, virus excretion, and peripheral blood lymphocyte counts. Blood chemical parameters (including AST, ALT, CPK, and TBIL) and viral excretion using pharyngeal and rectal swabs were analyzed.Results  Infected cats showed elevated body temperature up to 41·3°C starting from day 1 or 2 p.i. All infected cats excreted virus in pharyngeal swabs within 2 days p.i. co‐inciding with the development of clinical signs (anorexia, depression, and labored breathing) irrespective of the infection route. Virus dissemination occurred through cell‐free and cell‐associated viremia. Infected cats developed lymphopenia, hepatic necrosis, pneumonia, and significantly elevated levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), creatine phosphokinase (CPK), and TBIL.Conclusions  The experiments show that the gastrointestinal tract can serve as portal for the entry of HPAIV H5N1 into cats. Infection routes used did not influence viral tissue tropism and course of disease.

Published: August 2010

AbstractSudden unexpected death in epilepsy (SUDEP) is the most frequent epilepsy‐related cause of death and is characterized by an absence of any identifiable cause of death at post‐mortem, suggesting an underlying arrhythmogenic predisposition. This study sought to identify SUDEP cases in a review of post‐mortem records and to undertake genetic studies in key familial long QT syndrome (LQTS) genes. All autopsies performed from 1993‐2009 at a forensic centre in Sydney, Australia were reviewed and SUDEP cases identified. DNA was extracted from post‐mortem blood and the three most common LQTS genes, ie,KCNQ1,KCNH2 (HERG)andSCN5A, were amplified and analyzed. Sixty‐eight SUDEP cases were identified (mean age of 40 ± 16 years). Genetic analysis revealed 6 (13%) non‐synonymous (amino acid changing) variants inKCNH2(n = 2) andSCN5A(n = 4), all previously reported in LQTS patients. Specifically,KCNH2Arg176Trp andSCN5APro1090Leu were identified once in SUDEP cases and absent in control alleles. Both DNA variants have been previously identified in the pathogenesis of LQTS. The cause of SUDEP is currently unknown. Our results indicate that investigation of key ion channel genes should be pursued in the investigation of the relationship between epilepsy and sudden death.

AbstractProtease‐resistant prion protein (PrPSc) is diagnostic of prion disease, yet its detection is frequently difficult. Here, we describe a patient with a PRNP P105T mutation and typical familial prion disease. Brain PrPSc was undetectable by conventional Western blotting and barely detectable after phosphotungstate precipitation, where it displayed an atypical pattern suggestive of noncanonical conformation. Therefore, we used a novel misfolded protein assay (MPA) that detects PrP aggregates independently of their protease resistance. The MPA revealed the presence of aggregated PrP in similar amounts as in typical sporadic Creutzfeldt‐Jakob disease. These findings suggest that measurements of PrP aggregation with the MPA may be potentially more sensitive than protease‐based methodologies.

Abstract:  The aim of this study was to characterize the quality of celery petioles (Apium graveolens L. cv Golden Clause) from the external, middle, and internal zones of each plant. Harvest dates were 93 (HD1) and 124 (HD2) days after transplantation. Total weight (TW), total length (TL), total leaves number (LN), and petiole length of leaves (PL) for the 3 zones were measured. Physicochemical (color, b* and h; texture; total soluble solids, TSS; titratable acidity, TA; water content, WC), nutraceutical (ascorbic acid, AA; total quinones, TQ; browning potential, BP), and sensorial analysis (flavor, fibrosity, crunchiness) were done at harvest on petioles of each zone. No differences between harvesting dates were found in TW, TL, LN, and PL. Middle leaves had the highest PL. Harvest dates were not different in b*, h, TA, AA, and WC. Texture, TSS, BP, and TQ resulted higher in petioles of HD2 than in HD1. Similar TSS and TA were found in leaves of different plant zones. The yellow color of both external and internal zones was significantly higher than in the middle zone. The texture and BP was similar between the external and middle zones but the WC was lower in the external zone. Similarly, the AA content as well as the TQ was also lower than in the middle zone. Harvest delay improved the nutraceutical value in terms of BP and TQ, even though it also resulted in pithiness and fibrosity of the leaves. This study therefore suggests that the petioles of the middle zone when harvested at HD1 are the most suitable for consumption.Practical Application:  Celery is a vegetable reduced in calories, has a high nutritional value and its fresh petioles are mainly consumed in salads. The texture and flavor are the most important attributes that define consumers’ acceptability. As nutritional value, texture, and flavor may change with plant age and different zones of the plant, harvest date plays an important role on quality. Results indicate that harvest delay improved the nutraceutical value even though it also resulted in pithiness and fibrosity of the stalks. Petioles of the middle zone, when harvested at 93 d after transplanting, are the most suitable for consumers’ consumption.
Process Optimization and Consumer Acceptability of Salted Ground Beef Patties Cooked and Held Hot in Flavored Marinade
Authors: Shrestha Subash , Cornforth Daren , Nummer Brian A. 
Published: August 2010

Abstract:  Food safety is paramount for cooking hamburger. The center must reach 71 °C (or 68 °C for 15 s) to assure destruction of E. coli O157:H7 and other food pathogens. This is difficult to achieve during grilling or frying of thick burgers without overcooking the surface. Thus, the feasibility of partially or completely cooking frozen patties in liquid (93 °C water) together with hot holding in liquid was investigated. Initial studies demonstrated that compared to frying, liquid cooking decreased (P < 0.05) patty diameter (98 compared with 93 mm) and increased (P < 0.05) thickness (18.1 compared with 15.6 mm). Liquid cooked patties had greater weight loss (P < 0.05) immediately after cooking (29 compared with 21%), but reabsorbed moisture and were not different from fried patties after 1 h hot water holding (61 °C). Protein and fat content were not affected by cooking method. However, liquid cooked patties were rated lower (P < 0.05) than fried patties for appearance (5.7 compared with 7.5) and flavor (5.9 compared with 7.5). An 8‐member focus group then evaluated methods to improve both appearance and flavor. Salted, grill‐marked patties were preferred, and caramel coloring was needed in the marinade to obtain acceptable flavor and color during liquid cooking or hot holding. Patties with 0.75% salt that were grill‐marked and then finish‐cooked in hot marinade (0.75% salt, 0.3% caramel color) were rated acceptable (P < 0.05) by consumers for up to 4 h hot holding in marinade, with mean hedonic panel ratings > 7.0 (like moderately) for appearance, juiciness, flavor, and texture. Practical Application: Grill‐marked and marinade‐cooked ground beef patties reached a safe internal cooking temperature without overcooking the surface. Burgers cooked using this method maintained high consumer acceptability right after cooking and for up to 4 h of hot holding. Consumers and foodservice operations could use this method without specialized equipment, and instead use inexpensive and common equipment such as a soup pot or a restaurant steam table. Use of marinades (salt/caramel color or others) in this cooking and holding method provides a nearly endless culinary flavoring opportunity.
Recovery of Salmonella enterica Serovars Typhimurium and Tennessee in Peanut Butter after Electron Beam Exposure

Abstract:  The effect of electron beam (e‐beam) radiation on the recovery of Salmonella serotypes Tennessee (ATCC 10722) and Typhimurium (ATCC 14028) in creamy peanut butter over a 14‐d storage period at 22 °C was studied. Each Salmonella type was independently inoculated into peanut butter and subjected to e‐beam doses that ranged from 0 to 3.1 kGy, confirmed by film dosimetry. After 2‐, 4‐, 6‐, 8‐, and 14‐d of storage, microbial analyses were conducted. Survivors were recovered on growth and selective media using standard spread‐plating methods. Microbial counts (CFU/g) were log‐converted and differences were determined by ANOVA and Tukey's Honestly Significant Differences test. When samples were not e‐beam‐treated, there were no significant changes (P > 0.05) in microbial numbers over time. In e‐beamed samples, microbial numbers decreased over time; however, reductions were not always significant. Initial recovery rates (R‐rates) 2 d after e‐beam treatment were significantly different for the 2 strains of Salmonella and between recovery media (P < 0.05); however, these differences did not persist for the remainder of the storage period (P > 0.05) indicating that injured cells were not able to survive in the high‐fat, low‐water activity peanut butter environment. R‐rates for both strains of Salmonella were maintained until day 14 when there were significant reductions in Salmonella Typhimurium (P < 0.05). These results indicate that Salmonella Tennessee and Salmonella Typhimurium will survive in peanut butter when exposed to nonlethal doses of e‐beam irradiation. Practical Application: Electron beam (e‐beam) irradiation is an alternative to thermal processing; this technique inactivates microorganisms and insects that might be present in a food by generating radiation by accelerated electrons that inactivate organisms directly because of interaction with cell components and indirectly by producing free radicals that disrupt integrity of the cell membrane. E‐beam radiation will reduce the number of probable microbiological hazards that could be present while the food remains generally unaffected in texture, taste, and nutritional value. A recent study showed e‐beam irradiation to be effective at reducing both Salmonella Tennessee and Typhimurium in peanut butter by one log after exposure to less than 1 kGy, highlighting the need to explore this process further.
