    SURVEY OF APPLE GROWING, HARVESTING, AND CIDER MANUFACTURING PRACTICES IN WISCONSIN: IMPLICATIONS FOR SAFETY

    JOURNAL OF FOOD SAFETY, Issue 2 2000
    HEIDI E. ULJAS
    ABSTRACT To evaluate the safety of current apple growing, harvesting and cider manufacturing practices in Wisconsin, cider manufacturers were contacted in a three-phase survey. Results revealed that seasonal, small-scale production was characteristic of the industry. Most cider mills produced less than 5,000 gal/year; only 6% produced more than 20,000 gal/year. Most cider makers used only tree picked apples (86%), inspected apples before washing (94%), washed (93%) and brushed (87%) apples, but only 16% of mills sanitized washed apples. Most mills (92%) sanitized cider making equipment after each use; however, only a few sanitized between custom pressing apples from different customers. Respondents reported that they strived to improve cider safety by pasteurization (43% of all cider), UV light treatment (4%), use of preservatives (30%), and HACCP (17%). For 31% of all cider, however, processors relied solely on refrigeration and/or freezing. These results show that most cider mills practice many steps believed to enhance cider safety, but results also identify procedures that must be addressed to further improve cider safety. [source]

    Growing up Charismatic: Morality and Spirituality among Children in a Religious Community

    ETHOS, Issue 4 2009
    Thomas J. Csordas
    The first question has to do with the problem of how charisma can be successfully transferred to the second generation of a prophetic community. The second question has to do with how children come to be, and to act as, moral and spiritual beings. These questions converge in a particular way in the ethnographic setting of The Word of God Community: it is founded on a charismatic spirituality closely intertwined with a moral imperative, such that its viability depends on reproduction of that morality and spirituality among children of the founding generation. Data come from interviews with 38 children across three age groups (5,7, 10,12, and 15,17 years), conducted over a four-week period subsequent to a community schism, which left members in a state of reflection, self-examination, and openness. We focus on children's responses to a series of culturally specific vignettes designed to present various dilemmas of moral reasoning. In this highly charged context moral and spiritual life are based on an active engagement characterized by dynamic and contested processes, and it is through these processes that individuals make meaning out of and reconstruct the moral code of their culture.

    Growing Up in Guerrilla Camp: The long-Term Impact of Being a Child Soldier in El Salvador's Civil War

    ETHOS, Issue 4 2002
    Julia Dickson-Gõmez
    Many recent wars are characterized by high levels of civilian casualties, a large proportion of whom are women and children. Furthermore, an estimated 300,000 children are actively participating in 36 ongoing or recently ended conflicts around the world. However, there is a dearth of research on the long-term effects of war trauma experienced in childhood or children's active participation in armed conflicts. This article explores the long-term effects of children's active participation in the war in El Salvador by examining four young adults who fought with the guerrilla army as children and adolescents. Comparing these four cases with members of the community who joined and fought with the guerrilla as adults, it will be argued that traumatic experiences were even more devastating when they occurred in early childhood as they destroyed the ability to establish basic trust in competent and nurturing caretakers. Becoming a soldier created additional conflicts as these adolescent soldiers behaved in ways they felt were morally incorrect. Adolescent soldiers were also not given the opportunity to develop autonomy and learn adult peace-time roles. Both the psychological trauma suffered as children as well as continued economic scarcity and violence contribute to these campesinos' difficulties in creating meaningful lives as adults. [source]


    Synthesis and Optical Properties of KYF4/Yb, Er Nanocrystals, and their Surface Modification with Undoped KYF4,

    ADVANCED FUNCTIONAL MATERIALS, Issue 19 2008
    Helmut Schäfer
    Abstract KYF4/Yb3+, Er3+ nanocrystals with a mean diameter of approximately 13,nm were synthesized at 200,°C in the high boiling organic solvent N -(2-hydroxyethyl)ethylenediamine (HEEDA). The particles crystallize in the cubic phase known from , -NaYF4 and form transparent colloidal solutions in tetraethylene glycol (TEG) or propanol. Solutions containing 1,wt % of the nanocrystals in TEG display visible upconversion emission upon continuous wave (CW) excitation at 978,nm. Growing undoped KYF4 on the surface of the KYF4/Yb3+, Er3+ nanocrystals increases the upconversion efficiency by more than a factor of 20. The XRD data of these particles, display a slight increase in the mean particle size from 13 to 15.5,nm, indicating that only a part of the subsequently added KYF4 shell material is deposited onto the particle surface. Nevertheless the performed surface modification obviously leads to core/shell structured particles. [source]

Eight iridoid glucosides, catalpol, globularicisin, globularin, globularidin, globularinin, globularimin, lytanthosalin, and alpinoside, a flavon glycoside, 6-hydroxyluteolin 7- O -sophoroside, a lignan glycoside, syringaresinol 4,- O - , -glucopyranoside, and a phenylpropanoid glycoside, syringin, were also obtained and characterized. The structures of the isolates were elucidated on the basis of 1D- and 2D-NMR experiments as well as HR-MALDI-MS. [source]


    Temperature as a Single On-Off Parameter Controlling Nanoparticles Growing, Stabilization and Fast Disentanglement

    ADVANCED MATERIALS, Issue 38 2010
    Paula M. López-Pérez
    Thermoresponsive nanoparticles are synthesized from ionic random terpolymer precursors. A distinct temperature-dependent aggregation-redissolution behavior is observed within a subtle balance between polymer ionic charge and hydrophobic content, which is used for colloidal synthesis of nanoparticles in aqueous medium and without surfactants. The solution thermal history provides a robust mean to customize the size of nanoparticles that can be disentangled on command. [source]


    Growing up in a dangerous developmental milieu: The effects of parenting processes on adjustment in inner-city African American adolescents

    JOURNAL OF COMMUNITY PSYCHOLOGY, Issue 1 2006
    Alexander T. Vazsonyi
    The current longitudinal study examined the protective effects of parenting processes on measures of adolescent adjustment (health-compromising and violent behaviors) in a sample of high-risk, inner-city, poor African American youth ( N = 2,867). Parenting processes played an important role in this dangerous developmental milieu. For male adolescents, they accounted for 26 to 37% in health-compromising behaviors and 16 to 24% of the total variance in violent behaviors over time. Multigroup SEM analyses by sex and age groups (early, middle, and late adolescents) indicated no differences of these effects across groups. Findings provided evidence that parenting processes are salient for a high-risk, inner-city minority population in understanding and predicting health-compromising and violent behaviors. © 2006 Wiley Periodicals, Inc.

    Genetic and Pathogenic Variation Among Tobacco Black Shank Strains of Phytophthora parasitica var. nicotianae from the Main Tobacco Growing in China

    JOURNAL OF PHYTOPATHOLOGY, Issue 5 2003
    X. G. Zhang
    Abstract Pathogenic and genetic variability among seven populations of Phytophthora parasitica var. nicotianae from individual tobacco fields (Yunnan, Shandong, Henan, Heilongjiang, Shanxi, Fujian and Sichuan provinces) were investigated using pathogenicity and randomly amplified polymorphic DNA (RAPD) analyses; 63 strains were isolated from different fields of seven tobacco growing regions, using tobacco cv. Hongda as a baiting host. Pathogenic variability was evaluated in greenhouse studies using five tobacco cultivars that have different levels of resistance to tobacco black shank; 75 and 73% of the strains were pathogenic on M3 and M4, 29 and 33% on M1 and M2, and 94% were pathogenic on M5, respectively. Disease severity incited by different strains varied significantly on individual tobacco cultivars. The percentage of strains pathogenic on different cultivars varied among locations. Genotypic variation among 63 strains was evaluated by RAPD analysis. Ten primers detected 89 polymorphic bands. Cluster and principal coordinates analysed cluster groups. the minor group contained 26 strains, and major group contained 37 strains. Estimates of genetic diversity based on RAPD analysis ranged from 0.24 to 0.34 within populations to 0.36 among all strains from all populations. Phytophthora parasitica var. nicotianae populations were genotypically and phenotypically variable, but no distinct genotypic differences were identified among populations from the seven locations.

    Issues in Growing a Family Business: A Strategic Human Resource Model

    JOURNAL OF SMALL BUSINESS MANAGEMENT, Issue 1 2001
    Sandra W. King
    The conceptual literature on family businesses suggests that family businesses have difficulty managing their human resources, especially when it concerns a family member or the transition from the founder to the successor. The authors empirically examined the assumptions raised in the conceptual literature regarding whether family businesses were experiencing human resource problems in growing their business and what factors enabled or constrained the ability of their businesses to grow. The authors used in-depth interviewing to collect data in order to emphasize the depth of the issue. Using content analysis with subject matter experts coding the data, the authors sought to mine the richness of data. Finally, the authors analyzed the data using Elliot Jaques' Stratified Systems Theory as a model to examine the strategic human resource issues and to draw some tentative conclusions. [source]

    Wennergren G, Ekerljung L, Alm B, Eriksson J, Lötvall J, Lundbäck B. Asthma in late adolescence , farm childhood is protective and the prevalence increase has levelled off. Pediatr Allergy Immunol 2010: 21: 806,813. © 2010 John Wiley & Sons A/S While the prevalence of and risk factors for asthma in childhood have been studied extensively, the data for late adolescence are more sparse. The aim of this study was to provide up-to-date information on the prevalence of and risk factors for asthma in the transitional period between childhood and adulthood. A secondary aim was to analyze whether the increase in asthma prevalence has levelled off. A large-scale, detailed postal questionnaire focusing on asthma and respiratory symptoms, as well as possible risk factors, was mailed to 30 000 randomly selected subjects aged 16,75 in Gothenburg and the surrounding western Sweden region. The present analyses are based on the responses from 1261 subjects aged 16,20 (560 men and 701 women). The prevalence of physician-diagnosed asthma was 9.5%, while 9.6% reported the use of asthma medicine. In the multivariate analysis, the strongest risk factors for physician-diagnosed asthma and other asthma variables were heredity for asthma and heredity for allergy, particularly if they occurred together. Growing up on a farm significantly reduced the prevalence of physician-diagnosed asthma and the likelihood of using asthma medication, OR 0.1 (95% CI 0.02,0.95). Smoking increased the risk of recurrent wheeze, long-standing cough, and sputum production. In conclusion, the prevalence of physician-diagnosed asthma and the use of asthma medication in the 16- to 20-yr age group support the notion that the increase in asthma prevalence seen between the 1950s and the 1990s has now levelled off. In line with the hygiene hypothesis, a farm childhood significantly reduced the likelihood of asthma. The adverse effects of smoking could already be seen at this young age. [source]

    Morphological, Small Subunit rRNA, and Physiological Characterization of Trimyema minutum (Kahl, 1931), an Anaerobic Ciliate from Submarine Hydrothermal Vents Growing from 28°C to 52°C

    THE JOURNAL OF EUKARYOTIC MICROBIOLOGY, Issue 3 2002
    MANUELA BAUMGARTNER
    ABSTRACT. A thermophilic strain of Trimyema minutum was isolated from the hydrothermally heated sea floor at Vulcano Island (Italy) and cultivated monoxenically on Marinobaaer sp. and Methanococcus thermolithotrophicus. It can be propagated strictly an aerobically and is sensitive to oxygen: if exposed to air at 48°C all cells die within 60 min. It grows from 0.45,7.2% (w/v) salt and at pH 6.0,8.0. The isolate is the most extreme thermophilic ciliate which ever has been cultivated, exhibiting an optimal growth temperature of 48°C (doubling time 6 h). Growth occurs between 28°C and 52°C. Trimyema minutum is redescribed using live observation and silver impregnation. Its morphology and the small subunit ribosomal RNA sequence is distinctly different from that of T. compressum, but morphology is highly similar to that of T. shoalsiaNerad et al. 1995, which is thus probably a junior synonym of T. minutum. To stabilize the bewildering species taxonomy in Trimyema. we suggest to recognize our population as a neotype of T. minutum. [source]


    Recruiting and Retaining Physicians in Very Rural Areas

    THE JOURNAL OF RURAL HEALTH, Issue 2 2010
    Carolyn M. Pepper PhD
    Abstract Context: Recruiting and retaining physicians is a challenge in rural areas. Growing up in a rural area and completing medical training in a rural area have been shown to predict decisions to practice in rural areas. Little is known, though, about factors that contribute to physicians' decisions to locate in very sparsely populated areas. Purpose: In this study, we investigated whether variables associated with rural background and training predicted physicians' decisions to practice in very rural areas. We also examined reasons given for plans to leave the study state. Methods: Physicians in the State of Wyoming (N = 693) completed a questionnaire assessing their background, current practice, and future practice plans. Findings: Being raised in a rural area and training in nearby states predicted practicing in very rural areas. High malpractice insurance rates predicted planning to move one's practice out of state rather than within state. Conclusions: Rural backgrounds and training independently predict practice location decisions, but high malpractice rates are the most crucial factor in future plans to leave the state. [source]


    Histological Studies of Growing and Mature Antlers of Red Deer Stags (Cervus elaphus)

    ANATOMIA, HISTOLOGIA, EMBRYOLOGIA, Issue 3 2009
    M. Cegielski
    Summary This study aims at presenting histology of growing and mature antlers in red deer stag (Cervus elaphus). Growing antlers constitute a model organ for examining regeneration processes of tissues because they are the only mammalian appendages capable of regeneration. Histological study revealed that the tip of a growing antler consists of hairy skin, perichondrium, mesenchyme and chondroprogenitors area. By performing immunochistochemistry, we found that cell expressing Ki-67 and PCNA antigens were localized in basal layer of epidermis, skin glands and beneath their secretory sections, mesenchyme as well as within and in the vicinity of central blood vessels. Ultrastructurally, cells from chondroprogenitors zone have chondroblast-like morphology and take part in producing of collagen fibres followed by the process of cartilage mineralization. However, mature antlers also consist of lamellar osseous tissue. [source]


    The Effect of Testosterone on Gastrocnemius Muscle Fibres in Growing and Adult Male and Female Rats: A Histochemical, Morphometric and Ultrastructural Study,

    ANATOMIA, HISTOLOGIA, EMBRYOLOGIA, Issue 2 2003
    . Üstünel
    Summary In this study, the effect of testosterone on gastrocnemius muscle fibres in growing and adult rats (male and female) was examined using histochemical, morphometric and ultrastructural techniques. After physiological saline (PS), olive oil (OvO) or olive oil + testosterone (OvOT) injections on 72 rats (growing and mature, 36 male and 36 female), the sample tissues of fibre types of the gastrocnemius muscle taken were examined by histochemical [alkaline adenosine triphosphatase (alk-ATPase), acid ATPase (ac-ATPase)], morphometric and ultrastructural techniques. In PS-injected control groups, the gastrocnemius muscle of both sexes contained all the fibre types studied [slow-oxidative muscle fibres (type I), fast-oxidative glycolytic muscle fibres (type IIA) and fast-glycolytic muscle fibres (type IIB)]. The type I fibres had the smallest diameter, type IIA had a medium diameter and type IIB fibres had the largest diameter. In OvO-injected groups, it was observed that the OvO had little effect on the gastrocnemius muscles of either sex, although there was significant enlargement of type IIB fibres. After the injection of OvOT, hypertrophy of muscle fibres was determined by morphometric study. The biggest increase in diameter was on type I fibres. In addition, degenerations on some mitochondria, accumulation of lipid droplets on type I and type II fibres, an increase in glycogen particles, bifurcation of myofibrils, an increase in the number and diameter of units resembling T tubules and an increase in ribosomal content were also observed in the same group by transmission electron microscope. Consequently, it was determined that testosterone can induce protein synthesis in gastrocnemius muscle fibres, and induces changes in shape and size, and also can change the appearance and the number of fibres.

    The influence of ultraviolet radiation on growth, photosynthesis and phenolic levels of green and red lettuce: potential for exploiting effects of ultraviolet radiation in a production system

    ANNALS OF APPLIED BIOLOGY, Issue 3 2010
    E. Tsormpatsidis
    Studies have shown that natural ultraviolet (UV) radiation increases secondary products such as phenolics but can significantly inhibit biomass accumulation in lettuce plants. In the work presented here, the effect of UV radiation on phenolic concentration and biomass accumulation was assessed in relation to photosynthetic performance in red and green lettuce types. Lettuce plants in polythene clad tunnels were exposed to either ambient (UV transparent film) or UV-free conditions (UV blocking film). The study tested whether growth reduction in lettuce plants exposed to natural UV radiation is because of inhibition of photosynthesis by direct damage to the photosynthetic apparatus or by internal shading by anthocyanins. Ambient levels of UV radiation did not limit the efficiency of photosynthesis suggesting that phenolic compounds may effectively protect the photosynthetic apparatus. Growth inhibition does, however, occur in red lettuce and could be explained by the high metabolic cost of phenolic compounds for UV protection. From a commercial perspective, UV transparent and UV blocking films offer opportunities because, in combination, they could increase plant quality as well as productivity. Growing plants continuously under a UV blocking film, and then 6 days before the final harvest transferring them to a UV transparent film, showed that high yields and high phytochemical content can be achieved complementarily.

    Repeated Growing and Annealing Towards ZnO Film by Metal-Organic CVD,

    CHEMICAL VAPOR DEPOSITION, Issue 7-9 2009
    Chia-Cheng Wu
    Abstract ZnO deposited on sapphire substrate is investigated as a function of growth temperature in the range 350,650,°C. The surface morphology of ZnO structures changes significantly with increasing growth temperature. Though ZnO crystal quality and optical property can be improved under high growth temperature, ZnO is inclined to form nanostructures. Therefore, we propose the repeated growing and annealing (RGA) growth mode as a reliable and reproducible way for the growth of ZnO film. The RGA growth mode is performed at a growth temperature of 450,°C for 8,min, an anneal temperature of 650,°C for 20,min, and repeatedly switched between growing and annealing. Meanwhile, we compare the effects of annealing under Ar, N2, and O2, and found that a low resistivity of 3.4,×,10,3,, cm and a high mobility of 85.2,cm2 V,1 s,1 can be obtained annealing under N2.

    Pulmonary Function and Ventilatory Limitation to Exercise in Congenital Heart Disease

    CONGENITAL HEART DISEASE, Issue 1 2009
    Paolo T. Pianosi MD
    ABSTRACT Pulmonary function in older children and adolescents following surgical repair of congenital heart disease is often abnormal for various reasons. Many of these patients report symptoms of exercise intolerance although the reason(s) for this symptom can be complicated and sometimes interrelated. Is it simply deconditioning due to inactive lifestyle, chronotropic or inotropic insufficiency? or could there indeed be ventilatory limitation to exercise? These are the questions facing the clinician with the increasing frequency of patients undergoing repair early in life and growing into adulthood. Understanding pulmonary functional outcomes and means of determining ventilatory limitation to exercise is essential to thoroughly address the problem. This article reviews pulmonary function in patients with congenital heart disease and then describes a newer technique that should be applied to determine ventilatory limitation to exercise.

    Preparation of shuttle-like Sb2S3 nanorod-bundles via a solvothermal approach under alkaline condition

    CRYSTAL RESEARCH AND TECHNOLOGY, Issue 2 2010
    Ling Zhang
    Abstract Uniform shuttle-like Sb2S3 nanorod-bundles were synthesized via a polyvinylpyrrolidone (PVP) assisted solvothermal approach under alkaline condition, using antimony chloride (SbCl3) and thiourea (CH4N2S, Tu) as the starting materials in ethanol. The phase structure, composition and morphology of the product were characterized by means of X-ray diffraction (XRD), energy dispersive X-ray spectrometry (EDS), transmission electron microscopy (TEM), and high-resolution transmission electron microscopy (HRTEM). XRD and EDS results confirm that the synthesized Sb2S3 nanorod-bundles have an orthorhombic structure and an atomic ratio of 3:2 for S:Sb. TEM and HRTEM results show that the shuttle-like Sb2S3 bundles are composed of nanorods with a size distribution of 20-40 nm and growing along c-axis. Furthermore, experiments under different reaction conditions were carried out and the mechanism for the growth of nanorod-bundles was discussed (© 2010 WILEY-VCH Verlag GmbH & Co.
