    2012-07-01

    In March 2008 the ground breaking project financing of the 95 MW Havsnaes wind farm was completed. Havsnaes represents one of the cornerstones in portfolio of Venus Vind, controlled by HgCapital, where sustainable Scandinavian strength is build through industrial scale wind farms with local presence. At the time, Havsnaes represented the largest energy project financing in the market, it is also the first true project financing of a major Swedish wind farm. The aim of this study is to highlight the process of project financing and additional lessons learnt from the Havsnaes transaction. Investment in renewable energy projects often includes international investors. We welcome the growing Swedish wind market, banks and other financial institutions, politicians and other relevant decision makers to take part of our findings. Sponsorship provided by the Swedish Energy Agency has enabled the completion of this study.

    On-farm biosecurity is an important part of disease prevention and control, this applies to live animal contacts as well as indirect contacts e.g. via professionals visiting farms in their work. The objectives of this study were to investigate how professionals visiting animal farms in Sweden in their daily work perceive the on-farm conditions for biosecurity, the factors that influence their own biosecurity routines and what they describe as obstacles for biosecurity. Suggestions for improvements were also asked for. Questionnaires were distributed to professionals visiting farms in their daily work; veterinarians, livestock hauliers, artificial insemination technicians, animal welfare inspectors and cattle hoof trimmers. The sample was a convenience sample, based on accessibility to registers or collaboration with organisations distributing the questionnaire. Respondents were asked about the availability of certain biosecurity conditions related to farm visits, e.g. if facilities for hand washing were available, how important different factors were for their own routines and, through open ended questions, to describe obstacles and suggestions for improvement. After data cleaning, there were responses from 368 persons. There was a difference in the proportion of visited farms reported to have certain biosecurity measures in place related to animal species present on the farm. In general, visited pig farms had a higher proportion of biosecurity measures in place, whereas the conditions were poorer on sheep and goat farms and horse farms. There were also differences between the visitor categories; the perceived conditions for biosecurity varied between the groups, e.g. livestock hauliers did not have access to hand washing facilities as often as veterinarians did. In all groups, a majority of the respondents perceived obstacles for on-farm biosecurity, among veterinarians 66% perceived that there were obstacles. Many of the reported obstacles related to the very

    Full Text Available Gendered relations in resource access and farming are two important intersecting themes of gender studies in a northern rural context. However, conventional analysis and perceptions of the economy conceal the contribution of women within families, in businesses and in the labor market. This article demonstrate the significance of capital to farming women’s engagement with agriculture using a Swedish case study, based on descriptive analyses of data from the Federation of Swedish Farmers. To disclose the embodiment of family farming, gendered control of land, business activities and farm incomes is analyzed. On this empirical basis, we argue for reconstitution of farm-related entrepreneurial research, rural development policies and rural gender studies from a new material feminist approach. Access to resources, typically land, together with social forces and embodied experiences constitute the basis of strategic focus and agency. We demonstrate that acknowledgement of access to resources in the research process and in the understanding of social relations, resistance and situated knowledge are essential.

  8. Forecasting Production Losses at a Swedish Wind Farm

    DEFF Research Database (Denmark)

    Production loss due to icing has been identified as a problem both when siting turbines in cold climates, and when making forecasts of energy production for wind park management and energy markets. The Makkonen icing model (Makkonen, 2000), driven by output from the WRF mesoscale model, has been...... shown to predict periods of icing at a wind farm in northern Sweden (Davis et al, 2012) with improved skill compared to persistence and threshold models. Based on these results, we have developed a statistical model to estimate the loss of production at the wind park due to these icing periods. We...... compared this statistical model with a simpler method that does not rely on a physical icing model. In that method meteorological icing is identified as periods when WRF forecasts clouds and the temperature is below freezing. During these periods it is assumed that there is no production from the turbines...

  9. Production conditions of bioenergy in Swedish agriculture; Produktionsfoerutsaettningar foer biobraenslen inom svenskt jordbruk

    Energy Technology Data Exchange (ETDEWEB)

    Boerjesson, Paal

    2007-05-15

    The overall aim of this report is to analyse and describe the production conditions of bioenergy in Swedish agriculture and how these conditions can vary due to different factors. The conclusion is that the potential for producing bioenergy in Swedish agriculture will vary significantly depending on which energy crops are cultivated, which type of agricultural land is utilised and the geographical location of the production. Furthermore, different crop residues and other by-products from agriculture, utilised for energy purposes, will affect the bioenergy potential. To which extent this physical/biological potential will be utilised in the future depends mainly on economic conditions and financial considerations. These aspects are not included in this study. The report starts with a description of current crop production in Sweden, expressed in energy terms, the energy needed for this production and the regional variation in crop yields. The local variations in cultivation conditions are also analysed, as well as variations over the area of a single farm. Another aspect discussed is the production conditions of energy crops on previous farm land not currently utilised. The report includes an analysis of the potential supply of crop residues and other by-products for energy purposes, such as straw, tops and leaves of sugar beets, manure etc, as well as the regional variation of these residues and by-products. A similar analysis is made of the regional production conditions and potential biomass yields of traditional crops and new energy crops. These analyses also include energy balance calculations showing the energy input needed for different production systems in relation to the harvested biomass yield, and the potential for increased biomass yields in the future. Based on the findings of these various analyses, calculations are made showing some examples of how much bioenergy Swedish agriculture can deliver, depending on how much agricultural land is utilised for

  11. Psychosocial working conditions and cognitive complaints among Swedish employees.

    Directory of Open Access Journals (Sweden)

    Cecilia U D Stenfors

    Full Text Available BACKGROUND: Cognitive complaints involving problems with concentration, memory, decision-making and thinking are relatively common in the work force. The sensitivity of both subjective and objective cognitive functioning to common psychiatric conditions, stress levels and to cognitive load makes it plausible that psychosocial working conditions play a role in cognitive complaints. Thus, this study aimed to test the associations between psychosocial work factors and cognitive complaints in nationally representative samples of the Swedish work force. Cross-sectional (n = 9751 and prospective (n = 3644; two time points two years apart sequential multiple regression analyses were run, adjusting for general confounders, depressive- and sleeping problems. Additional prospective analyses were run adjusting for baseline cognitive complaints. CROSS/SECTIONAL RESULTS: High quantitative demands, information and communication technology (ICT demands, under qualification and conflicts were positively associated with cognitive complaints, while social support, good resources at work and over qualification were negatively associated with cognitive complaints in all models. Skill discretion and decision authority were weakly associated with cognitive complaints. Conflicts were more strongly associated with cognitive complaints in women than in men, after adjustment for general confounders. PROSPECTIVE RESULTS: Quantitative job demands, ICT demands and under qualification were positively associated with future cognitive complaints in all models, including when adjusted for baseline cognitive complaints. Decision authority was weakly positively associated with future cognitive complaints, only after adjustment for depressive- and sleeping problems respectively. Social support was negatively associated with future cognitive complaints after adjustment for general confounders and baseline cognitive complaints. Skill discretion and resources were negatively

  12. A survey of straw use and tail biting in Swedish pig farms rearing undocked pigs.

    Tail biting is a common problem in intensive pig farming, affecting both welfare and production. Although routine tail docking is banned within the EU, it remains a common practice to prevent tail biting. Straw as environmental enrichment has been proposed as an alternative to tail docking, but its effectiveness against tail biting and function in manure handling systems have to be considered. The aim of the study was to survey how pigs with intact tails are raised and how tail biting is handled in Sweden, where tail docking is banned through national legislation. The study emphasises straw usage and its association with tail biting pigs and problems in the manure handling system. The expectation is that this information could be conveyed to the rest of the EU to reduce the need for tail docking. In a telephone survey of randomly selected Swedish pig farmers (46 nursery and 43 finishing pig units) with at least 50 sows or 300 finishing places, it was found that straw was used by 98% of the farmers. The median daily straw ration provided was 29 g/pig for nursery and 50 g/pig for finishing pigs in systems with partly slatted flooring. The reported prevalence of tail biting was 1.6% at slaughter. The majority of farmers reported that they never had manure handling problems caused by straw (56% of nursery units and 81% of finishing pig units). A proportion of farmers (37%) also provided with additional material apart from straw on some occasions, which may have affected tail biting prevalence and manure handling problems. Swedish farmers rear undocked pigs without large problems with tail biting. Straw is the main manipulable material used, and additional manipulable material is used to various extents. The low incidence of straw obstructing the manure handling systems implies that it is indeed possible to use straw in partly slatted flooring systems, reducing the need for tail docking. The impact of using additional manipulable material is unknown and requires more

    There is a lack of knowledge in women's and men's experience of miscarriage. The Revised Impact of Miscarriage Scale (RIMS) has been used in United States to measure the experiences after miscarriage. The first objective was to test the consistency of RIMS for Swedish conditions. The second purpose of this study was to compare Swedish and American couples' experience of miscarriage by use of the RIMS. Forward and back translation was used for translating RIMS into Swedish. This is a hospital-based comparative study including Swedish couples (n = 70) and American couples (n = 70). The couples were matched by the women's age, week of miscarriage and number of children. All participants answered socio-demographic, fertility and depression-scale questions in addition to RIMS. Cronbach's alpha analysis was above 0.650, the mean value was 0.824. There was no significant difference between the Swedish and American participants on the factors 'Isolation/Guilt' and 'Devastating event', but the Swedish women and men scored significantly lower on the factor 'Loss of baby' than the American women and men. The men, Swedish and American combined, scored lower than the women in all factors but the correlation within the couples was similar for both Swedish and American couples. The high consistency between the countries suggests that the RIMS questionnaire is reliable for both women and men to be used in both countries and two of three factors were similar between the two countries.

    Pena Diaz, Alfredo; Hahmann, Andrea N.; Mann, Jakob

    The net annual energy production (AEP) of the Hanstholm Wind Farm is 158 GWh per year for the Siemens SWT-3.6-120 turbine and 140 GWh for the Vestas V112-3.0 turbine. These values have an uncertainty (standard deviation) of 6%. This result is mainly based on the data for Risø DTU’s test station...... at Høvsøre where wind speeds are measured at approximately the same height as the turbines at Hanstholm and where the terrain is similar. On top of that meso-scale modeling has been used to extrapolate the climatology from Høvsøre to Hanstholm increasing the AEP by almost 6% compared to just using...... the Høvsøre climatology directly. This method of extrapolation is rather new, but several older investigations indicate that the wind resource at Hanstholm is slightly higher than at Høvsøre.

    In recent years reports from a number of countries, including Sweden, describe problems with diarrhoea in newborn piglets despite the use of previously effective preventive measures. This seemingly altered disease pattern of neonatal porcine diarrhoea (NPD) warrants investigations on the magnitude and manifestation of the problem. The aim of the present study was to investigate the herd-level prevalence of NPD in Sweden and to describe disease characteristics and intervention strategies used in affected herds. To obtain this information a questionnaire was developed and sent out to 170 randomly selected herds. The presence of NPD in the herds was specified as "Yes", "No" or "Occasional cases" during the preceding year. A response rate of 58% (98/170) was achieved. The total prevalence of farmer experienced NPD, including occasional cases was 79.6% (95% CI 70.6-86.4%). Most herds (85%; 83/98) employed maternal vaccination against enterotoxigenic Escherichia coli (ETEC). The most common treatment regimens used in affected herds included antimicrobials only (43%; 18/42) or antimicrobials in combination with supplementary fluids (33%; 14/42). Trimethoprim in combination with a sulphonamide was the drug of choice in 57% (24/42) of the affected herds whereas the remaining herds used a broad range of other antimicrobials (neomycin, amoxicillin, fluoroquinolones, penicillin, and tylosin). Furthermore, the risk of experiencing NPD was found to be higher in herds with >200 sows (OR = 4.0) compared to herds with <200 sows and in herds where more ambitious efforts (such as providing supplemental colostrum or practicing split-suckling) were made to save weak-born piglets (OR = 4.4). The results of the present study indicate that Swedish farmers commonly experience NPD in their herds, often despite vaccination against ETEC. Considering the extent of this problem and its contribution to antimicrobial usage, improving alternative control strategies for NPD needs to be

    Falls in National Hunt races is a tragic part of the sport. The present study focuses on the relation between racing track conditions and the number of falls in Swedish jump racing. The assumption was that more horses fell on heavy or soft going than on good or firm going. Results from all jump...... races at Täby Racecourse (1992-2001) were recorded. Parameters registered were: type and number of races, racing surface and condition, total time to finish the race, number of starting horses and number of falls. In this period 212 races, corresponding to 1,556 horse starts, were registered. Falls were...... registered in 42 races and in total 61 horses fell. The fall frequency on horse level was significantly higher in steeplechases than in hurdle races (odds ratio =3.69; 95% confidence interval (CI) = 1.99-6.85). For the steeplechases recorded in this study, significantly more falls were seen in long distance...

    2005-01-01

    The most important issues in the European energy sector today are how to increase competitiveness on the energy markets, reduce both CO2 emissions and dependence on imported fuels. These issues are also important aspects of Swedish energy policy. In Sweden, the district heating (DH) sector has commonly been used to achieve Swedish energy policy goals. However, the ongoing integration and deregulation of the energy markets in Europe now means that the Swedish DH sector can also play an important role in achieving international targets. This thesis investigates the extent to which the Swedish DH sector can contribute to compliance with current energy policy targets, both international and Swedish. The study consisted of simulations of the Swedish DH sector response to various policy instruments in a model that takes the local features of virtually all Swedish DH systems into account. The findings show, for example, that there is great potential for combined heat and power (CHP) generation in the Swedish DH sector. By exporting this CHP electricity to other European countries with less effective and fossil dependent power generation plants, the CO2 emissions from the European energy sector could be substantially reduced. This would also result in increased security of supply and competitiveness in the EU, since fuel use would be more effective. In Sweden, increased CHP generation would also be a way of maintaining an effective national security of supply of power

    2015-01-01

    Leaders and co-workers in Swedish public sector organizations are exposed to demanding psychosocial working conditions; more knowledge about workplace-based interventions in this sector of working life is needed. To compare co-workers' and leaders' self-ratings of health and psychosocial working conditions, and investigate how prevention and rehabilitation in Swedish public sector workplaces affects these ratings. The longitudinal panel data consisted of 311 individuals (20 leaders, 291 co-workers) at 19 workplaces. Based on questionnaire data, statistical analyses were performed using Mann-Whitney U-Test, pair-wise Spearman correlations, a mixed between-within subjects ANOVA and Friedman's test. Results indicate differences in how the leaders and the co-workers judge their health and psychosocial working conditions. Leaders report work content that is more varied and interesting as well as more possibilities for personal development through work, yet they also report more tiredness, concern over managing their work situation and time pressure at work. Comparisons of mean values for used indicators show some improvements after one year, but also several non-significant or negative time trends two years after the interventions were initiated. The study provides some support for experienced differences between co-workers' and leaders' health and psychosocial working conditions in public sector workplaces, indicating the importance of different workplace-oriented prevention and rehabilitation interventions for these two categories of employees.

    Two migrant farm labor camps were observed during two summer harvesting seasons. A part of the observations consisted of interviews with 104 farm laborers, with 16 of them being interviewed intensively. Migrant farm workers were exploited by the crew boss and the farm owner, and they in turn exploited each other. Consequently, many workers left farm work. Those who remained in the camps adapted their attitudes and their views to the conditions. Though they had a begrudging respect for the crew boss, they showed an overriding concern with exploitation. They conveyed a numbness about life, themselves, and their place in society; this numbness was combined with self criticism and an attempt to maintain some self-respect. They expressed distrust for and suspicion of others, and though they could not articulate it very well, they felt great fear and anxiety. In order to diagnose and treat disorder in migrant farm workers, psychiatrists must understand the exploitive social setting of migrant farm work and the adaptations of workers to that setting.

    All changes in the regulation of pharmacies have an impact on the work carried out in pharmacies and also on patient safety, regardless of whether this is the intention or not. To compare staff apprehension regarding some aspects of patient safety and quality in community pharmacies prior to and after the 2009 changes in regulation of the Swedish community pharmacy market. Questionnaires targeted at pharmacy staff before and after the changes in regulation (in 2008, 2011/12, and 2012/13 respectively) used four identical items, making comparisons of some aspects possible. All four items demonstrated a significant decrease in the first survey after the changes as compared to before. In the second survey significant differences were found on the two items representing safety climate whereas the items representing team climate and management showed no significant differences. The comparison carried out in this study indicates a negative effect in Swedish community pharmacies on safety and quality issues, as experienced by pharmacy staff. It is recommended that the possible effects of healthcare reforms are assessed before implementation, in order to counteract conceivable decline in factors including patient safety and working conditions.

    Severe weather conditions have two primary impacts on wind farm operations. The first relates to understanding potential damage to the turbines themselves and what actions are required to mitigate the effects. The second is recognizing what conditions may lead to a full or partial shutdown of the wind farm with sufficient lead time to determine the likely inability to meet energy generation committments. Ideally, wind forecasting suitable for wind farm operations should be of sufficient fidelity to resolve features within the boundary layer that lead to either damaging conditions or useful power generation. Given the complexity of the site-specific factors that effect the boundary layer at the scale of typical land-based wind farm locations such as topography, vegetation, land use, soil conditions, etc., which may vary with turbine design and layout within the farm, enabling reliable forecasts of too little or too much wind is challenging. A potential solution should involve continuous updates of alert triggering criteria through analysis of local wind patterns and probabilistic risk assessment for each location. To evaluate this idea, we utilize our operational mesoscale prediction system, dubbed “Deep Thunder”, developed at the IBM Thomas J. Watson Research Center. In particular, we analyze winter-time near-surface winds in upstate New York, where four similar winds farms are located. Each of these farms were built at roughly the same time and utilize similar turbines. Given the relative uncertainty associated with numerical weather prediction at this scale, and the difference in risk assessment due to the two primary impacts of severe weather, probabilistic forecasts are a prerequisite. Hence, we have employed ensembles of weather scenarios, which are based on the NCAR WRF-ARW modelling system. The set of ensemble members was composed with variations in the choices of physics and parameterization schemes, and source of background fields for initial

    Full Text Available The paper presents economic analysis of growing of legume-cereal intercropping in conditions of organic farming. Results of the analysis are based on data monitoring in chosen organic farms that grow LCI. In the paper there is also compared economic efficiency of LCI grown in organic and conventional farming system. Methodological solution results from costingness and earnings monitoring of LCI production in five chosen organic farms in the period 2007–2008.When evaluating costs existing in individual variants of LCI growing it is necessary to say that the selection of individual machines and machine aggregations represents the most important factor of influencing direct costs, namely with regard to the size of organic farms and to the area of individual field blocks. Under conditions of organic farms, the LCI production is also significantly influenced also by agrotechnical (tillage operations. As compared with conventional farms, the final yield of both green fodder and grain is lower by 14–38%. Total direct costs per hectare of harvested LCI acreage ranged in case of fodder production from 9.249 CZK to 11.620 CZK per hectare. In case of grain production, the corresponding costs ranged from 8.848 to 9.970 CZK per hectare. In case of LCI, the direct costs of organic farms per unit of production of both fodder and grain consist mainly of material costs, which represent 63–76% and 61–68% of total expenses associated with production of fodder and grain, respectively. These direct costs are influenced also by higher prices of inputs.

    In Bangladesh, highly pathogenic avian influenza H5N1 is endemic in poultry. This study aimed to understand the biosecurity conditions and farmers' perception of avian influenza biosecurity in Bangladeshi small commercial chicken farms. During 2011-2012, we conducted observations, in-depth interviews and group discussions with poultry farmers in 16 farms and in-depth interviews with seven local feed vendors from two districts. None of the farms were completely segregated from people, backyard poultry, other animals, households, other poultry farms or large trees. Wild birds and rodents accessed the farms for poultry feed. Farmers usually did not allow the buyers to bring egg trays inside their sheds. Spraying disinfectant in the shed and removing feces were the only regular cleaning and disinfection activities observed. All farmers sold or used untreated feces as fish feed or fertilizer. Farmers were more concerned about Newcastle disease and infectious bursal disease than about avian influenza. Farmers' understanding about biosecurity and avian influenza was influenced by local vendors. While we seldom observed flock segregation, some farmers used measures that involved additional cost or effort to protect their flocks. These farmers could be motivated by interventions to protect their investment from diseases they consider harmful. Future interventions could explore the feasibility and effectiveness of low-cost alternative biosecurity measures.

    1. A cross-sectional study was conducted from September 2015 to July 2016 in South Tyrol, Northern Italy to examine the prevalence of gastrointestinal helminths in free-range laying hens under mountain farming production conditions. 2. A total of 280 laying hens from 14 free-range mountain farms (4 organic, 10 conventional) were randomly collected at the end of the laying period. Faecal samples were taken to analyse faecal egg counts (FEC) and faecal oocyst counts (FOC). The gastrointestinal tracts were removed post mortem and examined for the presence of helminths. 3. In faeces, FEC values averaged 258 eggs per g of faeces, which were dominated by Ascaridia galli and Heterakis gallinarum. Mean FOC was 80 oocysts/g. In the gastrointestinal tract, at least one nematode species was found in 99.3% of the examined hens. H. gallinarum was the most prevalent nematode (95.7%), followed by Capillaria spp. (66.8%) and A. galli (63.6%). Thirty per cent of the chickens were infected with cestodes (tapeworms). Correlation coefficients between worm counts of H. gallinarum, Capillaria spp. and A. galli ranged from 0.41 to 0.51. 5. The helminth prevalence did not differ between conventional and organic farms, whereas total worm burden was higher in organic compared with conventional farms (318.9 vs. 112.0). Prevalence and infection intensity did not differ between farms that used anthelmintic treatments and those that did not. 6. In conclusion, free-range laying hens under the studied mountain farming conditions are at high risk of nematode infection, especially in organic systems. The vast majority of hens are subclinical infected with at least one helminth species.

    Full Text Available In 2009 productivity data from 95 kindling to finishing rabbit farms in France were analysed to identify rearing factors and health conditions that influenced their productivity. Farm productivity, expressed on a yearly basis, was described with 4 productivity indices: doe fertility and prolificacy, viability of young rabbits in the nest and mortality during the fattening period. The productivity data were obtained with the technical support of the farm and expressed in a standardised way. The average numerical productivity observed in the sample of farms was 50.9 rabbits produced per doe and per year (CI95% [49.6-52.2]. The husbandry management and health conditions were described based on a questionnaire filled out during an interview with the farmer and a farm visit. Explanatory data were organised into meaningful blocks relative to biosecurity measures, del using a Partiamaternity management, the sanitary context and the farm structure. The relationship between the 4 thematic blocks and the productivity indices was studied in a single mol Least Squares (PLS regression model. Fertility (81.0%, CI95% [80.0-82.0] and viability of young at nest (85.1%, CI95% [85.0-85.3] and mortality rate during fattening: 7.2%, CI95% [6.4-7.9] were significantly associated with common factors relative to maternity management and the health context whereas prolificacy (9.7 live kits per parturition, CI95% [9.5-9.9] was mostly influenced by a specific set of variables pertaining to those 2 blocks. Farm structure and biosecurity measures had a limited impact on fertility and on kit viability before weaning. The health conditions of the doe herd and the fattening rabbits were found to be significantly associated with several productivity indexes, but their impacts on productivity were as high as the impact of the other blocks. Genetic strain of the females, doe replacement strategy and nursing and weaning practices appeared to significantly influence reproductive

    The study was conducted to determine yeasts present in the gastrointestinal tract (GIT) of piglets kept under experimental farm (EF) and commercial farm (CF) conditions. Ninety five German Landrace full- and half-sibling piglets were sacrificed at 39 days of age. Sixty eight piglets were weaned at 28th day of life, when they were offered one diet ad libitum. Twenty seven piglets remained unweaned by their dams. None of the piglets received any creep feed before weaning. Digesta samples were collected from 1/3 distal small intestine (SI), caecum and proximal colon. One hundred seventy three colonies of isolated yeasts were characterized by sequence analysis of the PCR-amplified D1/D2 domain of the 26S rRNA gene with following alignment of the recovered sequences to GenBank entries. From the 17 phylotypes found, isolates most closely related to Galactomyces geotrichum, Kazachstania slooffiae and Candida catenulata dominated in the GIT of CF piglets. Kazachstania slooffiae and Candida glabrata dominated in GIT of EF piglets. Sørenson and Morisita-Horn similarity indices between farms were low (0.44 and 0.54 respectively) and the Simpson diversity index was higher for EF (7.58) than for CF (4.34). The study brings new data on yeasts composition in the pig GIT and shows differences in yeasts biodiversity between farms operated at different hygiene conditions.

    Full Text Available The purpose of this study was to investigate the influence of the task conditions on 20-m side foot-kick accuracy among Swedish first league women’s soccer players. Twenty-three players performed three side foot-kick tests under different task conditions: stationary ball using match-relevant ball speed (SBRS and maximal ball speed (SBMS and a 5-m run with the ball from different approach angles (0°, 30°, and 60° to a predetermined position, where passing of the ball on the move was executed using match-relevant ball speed (RBRS. With each test, the players performed 30 side-foot kicks, alternating between kicking legs with the aim of hitting a target stick. The accuracy was determined using video analysis. The side foot-kick accuracy was significantly greater for SBRS, compared to RBRS and SBMS. For all three test variables, the preferred leg displayed greater accuracy. The preferred leg’s accuracy was greater for the approach angle of 30° compared to both 0° and 60°. A significant deviation from the target stick was found for the straight-ahead approach, in which the right-foot and left-foot kicks deviated to respectively the left and right of the stick; in contrast, for the approach angle of 60°, the deviation from the target stick was on the opposite side of the approach side for both legs.

    Full Text Available One of the activities of the Ministry of Agriculture and Forestry, Fishery and Mediterranean Agriculture Directorate, i. e. Fishery Directorate to be more specific, is the monitoring of conditions in freshwater fish farming. The objective of this work is to show conditions in freshwater fish farming during 1999. and to provide a production plan for 2000. It will also provide detailed insight into the present conditions in freshwater fish farming and into the production trends of this field. Regarding this issue, the »Questionnaire for the Monitoring of Conditions in Freshwater Fish Farming«, was sent to fish farmers aroud the country data was processed from 22 cap ponds and 13 trout ponds. Roughe estimates of conditions were conducted for 2 fish farms, since they haven’t yet returned the mandatoruy questionnaire, i. e. the necessary data. This work features data on the number of employees in fish farms, as well as their qualifications, on the actual production and distribution of farmed freshwater fish, on the areas where production was conducted and on the overall yield. Fish food, raw materials, used tools and incentive funds paid were also taken into consideration. The difficulties faced in this branch of the economy are also inicated. Compared to 1998, a slight decrease in the number of employees of freshwater fish farms has been recorded. The total number of employees in 1999 was 655, of which 555 were on carp ponds and 100 on trout ponds. Data on the qualifications of employees for 1999 show that most of them were unskilled workers, while highly skilled workers make up a minority in this work force. The total production of freshwater in 1999. amoounted to 6.185,51 tons. Of this amount 5.592,52 tons were warm-water fish specied and 592,99 tons were cold-water fish species. Compared to 1998, production decreased by 4,89 percent. Production for 2000 has been planned to increase by 22,15 percent, i. e. the production quantity is projected

    Full Text Available This paper shows the economic situation of economically weak farms in 8 countries of Central and Eastern Europe(CEE in 2010. The data were obtained from the survey on EU farms carried out under the FADN system. The studyincluded countries in which economically weak farms were the dominant farm type (i.e. Bulgaria, Estonia, Hungary,Latvia, Lithuania, Poland, Romania and Slovakia. The aim of the study was to assess the economic performance ofthose farms and indicate advantages of the competing farm types. The analysis was performed in terms of totalfactor productivity, income levels, assets and debt level. The influence of CAP instruments on managementefficiency was also demonstrated. The study found a high diversity in terms of production potential as well asfinancial condition of farms in particular countries, whereas one point of correspondence between farms is theprevalence of fixed assets, i.e. an excessive assets-to-area ratio, and the dominance of own capital in financingthose assets. Romanian, Polish and Bulgarian farms are characterised by the highest efficiency of use of currentoutlays and, in turn, a lower cost of the production unit, which accounted for 66%, 86% and 87% of the outputvalue respectively. In Latvia, Estonia and Slovenia, the costs exceeded the output value by 6%, 7% and 23%respectively and, as a result, the income of those farms was generated exclusively due to subsidies.

    More than 11 million Thai people (38%) work in agriculture, but since most are in the informal sector, government enforcement and support are very limited. As a result, working conditions on Thai farms vary greatly, putting the health of many agricultural workers at risk. A cross-sectional study in three Thai provinces collected information on the work activities and conditions of 424 farmers representing five farm types: rice, vegetable, flower, rice/vegetable, and flower/vegetable. The agricultural workers were mainly women (60%); their average age was 53 but ranged from 18 to 87 years. More than 64% worked more than 5 days/week. Seventy-four percent of them had only primary school education. A number of the health and hazardous working conditions surveyed were significantly different by farm type. Rice farmers were found to have the highest prevalence of allergies, nasal congestion, wheezing, and acute symptoms after pesticide use, while flower farmers had the lowest prevalence of these health outcomes. Rice farmers reported the highest prevalence of hazardous working conditions including high noise levels, working on slippery surfaces, sitting or standing on a vibrating machine, spills of chemicals/pesticides, and sharp injuries. The lowest prevalence of these working conditions (except noise) was reported by flower farmers. Vegetable farmers reported the highest prevalence knee problems, while rice farmers had the lowest prevalence. Among these farmers, more than 27 different types of pesticides were reported in use during the past year, with the majority reporting use once a month. The flower/vegetable farming group reported the highest frequency of good exposure prevention practices during pesticide use. They were the most likely to report using cotton or rubber gloves or a disposable paper masks during insecticide spraying. Those farmers who only grew vegetables had the lowest frequency of good exposure prevention practices, including use of personal

    Full Text Available In this paper the essential elements concerning cattle and swine rearing and growing conditions were given in order to establish welfare and biosecurity standards. These elements were formed according to detailed annual investigations on 11 cattle and 5 swine farms and include relevant spatial, microclimate and hygienic conditions. In order to establish welfare standards, certain spatial conditions have higher importance, such as correct construction and maintenance of beds, pens and yards, and type and quality of materials used to build beds and walls. It is necessary to enable movement of animals in stables and yards as basic physiological and ethologic needs, according to latest scientific data. Also, optimal temperature, relative humidity and air velocity insuring have to be considered, as well as quality ventilation in order to establish and preserve optimal microclimate conditions. Also, it must be pointed out that hygiene maintenance of stable surfaces and animal bodies on a regular bases is essential. Basic principles and criteria for welfare level assessment are given in this paper. According to results obtained in previous investigations, special attention is given to possibilities to correct rearing and growing conditions in cattle and swine farms in our country. .

    The objectives of this study were to identify and describe the demographics and social conditions as well as characteristics of the places of death in a randomly selected sample that died in a county in Sweden during 2001. The present study reports part of the findings from a larger study undertaken during 2003 using a survey design of retrospective reviews of death certificates, medical records, and nursing records. Among several noteworthy findings are: first, an examination of these individuals' living arrangements reveal not only a large and vulnerable group that lives alone at the end-of-life but also a group living separated from their partners near end-of-life; second, individuals differ with respect to residence prior to death, that is private homes versus residential care facilities, imparting highly different contexts of care at the end-of-life; and third, a high prevalence of institutionalized deaths demonstrates that places of death other than hospitals and residential care facilities are uncommon, if not rare. It is concluded that increased attention to the social circumstances of the time period surrounding individuals' at the end-of-life is essential. There is need to develop more integrated models of care for dying people. Contemporary services available are not designed to meet a wide range of peoples' needs at the end-of-life. Home-based care, residential care and hospital care must be adapted to the changing patterns of dying. The services available should be organized to the benefit of the users rather than around the providers. This is the first study of its kind of a Swedish sample and while the data are limited to one county in Sweden its findings may contribute to a deeper understanding of demographic and social patterns at the end-of-life in general.

    Full Text Available The rearing of poultry for meat production (broilers is an agricultural food industry with high relevance to the economy and development of some countries. Periodic episodes of extreme climatic conditions during the summer season can cause high mortality among birds, resulting in economic losses. In this context, ventilation systems within poultry houses play a critical role to ensure appropriate indoor climatic conditions. The objective of this study was to develop a multisensor system to evaluate the design of the ventilation system in broiler houses. A measurement system equipped with three types of sensors: air velocity, temperature and differential pressure was designed and built. The system consisted in a laptop, a data acquisition card, a multiplexor module and a set of 24 air temperature, 24 air velocity and two differential pressure sensors. The system was able to acquire up to a maximum of 128 signals simultaneously at 5 second intervals. The multisensor system was calibrated under laboratory conditions and it was then tested in field tests. Field tests were conducted in a commercial broiler farm under four different pressure and ventilation scenarios in two sections within the building. The calibration curves obtained under laboratory conditions showed similar regression coefficients among temperature, air velocity and pressure sensors and a high goodness fit (R2 = 0.99 with the reference. Under field test conditions, the multisensor system showed a high number of input signals from different locations with minimum internal delay in acquiring signals. The variation among air velocity sensors was not significant. The developed multisensor system was able to integrate calibrated sensors of temperature, air velocity and differential pressure and operated succesfully under different conditions in a mechanically-ventilated broiler farm. This system can be used to obtain quasi-instantaneous fields of the air velocity and

    The condition detection of wind turbine is always an important issue which attract more and more attentions because of the rapid development of wind farm. And the on-line data analysis is also difficult since a lot of measured data is collected. In this paper, the abnormal data rejection and normal condition evaluation of wind turbine is processed. At first, since there are large amounts of abnormal data in the normal operation of wind turbine, which is probably caused by fault, maintenance downtime, power-limited operation and failure of wind speed sensor, a novel method is proposed to reject abnormal data in order to make more accurate analysis for the wind turbine condition. The core principle of this method is to fit the wind power curves by using the scatter diagram. The data outside the area covered by wind power curves is the abnormal data. The calculation shows that the abnormal data is rejected effectively. After the rejection, the vibration signals of wind turbine bearing which is a critical component are analyzed and the relationship between the vibration characteristic value and the operating condition of wind turbine is discussed. It will provide powerful support for the accurate fault analysis of wind turbine.

    The importance of farm yard manure and green manuring is well established for better crop production. The availability of farm yard manure is becoming difficult due to mechanized farming. An experiment was conducted with farm yard manure application in less quantity i.e. 5000 kg per hectare through fermenter with irrigation water as concentrated solution of farm yard manure. Four levels of nitrogen i.e. 0, 50, 100 and 150 kg/ha were applied through soil to Cotton crop planted on bed-furrows. Two years average results indicated that application of FYM at the rate of 5 metric ton per hectare through fermenter with 0, 50, 100 and 150 kgN/ha through soil increased seed cotton by 7 percent, on over all average basis of all fertilizer levels, as compared with no farm yard manure application. There was 6 percent increase with first 50 kgN/ha in the presence of FYM where as 100 kgN/ha gave 15% increase in seed cotton yield over no nitrogen application. It indicated that the efficiency of nitrogen at the rate of 100 kg/ha in the presence of farm yard manure was increased. There was 7, 15 and 20 percent increase in seed cotton with 50, 100 and 150 kgN/ha over no nitrogen on over all average basis of farm yard manure variables. Benefit cost ratio was more with FYM application alone.(author)

    1996-11-01

    The organization of the Swedish electricity market has been in a state of continual change since the electricity market reform was started in the early 1990s. The conditions for the development of the electricity market have changed since the new Electricity Act came into force on 1 January 1996. The purpose of the reform is to introduce greater competition on the electricity market and provide the consumers with greater freedom of choice and, by open trade in electricity, to create the conditions for more efficient pricing. Being the central energy authority, the Swedish National Board for Industrial and Technical Development, NUTEK, was entrusted by the Government with the task of following developments on the Swedish electricity market. The Network Authority, which has the supervisory function for the new electricity market, were entrusted by the Government with the task of following developments on the Swedish electricity market and regularly compiling and reporting current market information. The new electricity market has now been operative for ten months. The Network Authority has submitted to the Government a detailed report entitled `Developments on the electricity market`, dealing with the experience gained from the electricity market reform. The purpose of the publication is to provide the players on the electricity market - the decision makers, the media and the general public - with comprehensive and easily accessible information on the market conditions. The publication includes summaries of information on electricity production and use in recent years, the structure of the electricity market from the perspective of a player, electricity trade in Sweden and in northern Europe, electricity prices in Sweden and other countries, and the impact of the electricity sector on the environment

    Phosphorus flows in Swedish agriculture and food chain were studied by material flow analysis. The system studied included agriculture, food consumption, related waste and wastewater from private households and municipal wastewater treatment plants. Swedish farmland had net annual phosphorus inputs of ~12, 600 metric tons (4.1 kg P ha(-1)) in 2008-2010. The total import of phosphorus in food and feed to Sweden exceed imports of phosphorus in fertilizers. Despite strict animal density regulations relating to manure phosphorus content, phosphorus is accumulating on Swedish animal farms. The total quantity of manure produced greatly exceeds imported mineral phosphorus fertilizer and almost equals total phosphorus inputs to Swedish farmland.

    To investigate the possible influence of attendance at cultural events, reading books or periodicals, making music or singing in a choir as determinants for survival. A simple random sample was drawn of 15,198 individuals aged 16-74 years. Of these, 85% (12,982) were interviewed by trained non-medical interviewers between 1982 and 1983 about cultural activities. They were followed up with respect to survival until 31 December 1991. Swedish interview survey of living conditions comprising a random sample of the adult Swedish population. 12,675 people interviewed between 1982 and 1983. Survival of subjects after controlling for eight confounding variables: age, sex, education level, income, long term disease, social network, smoking, and physical exercise. 6,301 men and 6,374 women were followed up; 533 men and 314 women died during this period. The control variables influenced survival in the expected directions except for social network for men; a significant negative effective was found when the analysis was made separately for men and women. We found an influence on mortality when the eight control variables were controlled for in people who rarely attended events compared with those attending most often, the relative risk being 1.57 (95% confidence interval 1.18 to 2.09). Attendance at cultural events may have a positive influence on survival. Long term follow up of large samples with confounders that are well controlled for and with the cultural stimulation more highly specified should be used to try to falsify the hypothesis before experiments start.

    2011-09-01

    Full Text Available Abstract Background Internal control genes with highly uniform expression throughout the experimental conditions are required for accurate gene expression analysis as no universal reference genes exists. In this study, the expression stability of 24 candidate genes from Triticum aestivum cv. Cubus flag leaves grown under organic and conventional farming systems was evaluated in two locations in order to select suitable genes that can be used for normalization of real-time quantitative reverse-transcription PCR (RT-qPCR reactions. The genes were selected among the most common used reference genes as well as genes encoding proteins involved in several metabolic pathways. Findings Individual genes displayed different expression rates across all samples assayed. Applying geNorm, a set of three potential reference genes were suitable for normalization of RT-qPCR reactions in winter wheat flag leaves cv. Cubus: TaFNRII (ferredoxin-NADP(H oxidoreductase; AJ457980.1, ACT2 (actin 2; TC234027, and rrn26 (a putative homologue to RNA 26S gene; AL827977.1. In addition of these three genes that were also top-ranked by NormFinder, two extra genes: CYP18-2 (Cyclophilin A, AY456122.1 and TaWIN1 (14-3-3 like protein, AB042193 were most consistently stably expressed. Furthermore, we showed that TaFNRII, ACT2, and CYP18-2 are suitable for gene expression normalization in other two winter wheat varieties (Tommi and Centenaire grown under three treatments (organic, conventional and no nitrogen and a different environment than the one tested with cv. Cubus. Conclusions This study provides a new set of reference genes which should improve the accuracy of gene expression analyses when using wheat flag leaves as those related to the improvement of nitrogen use efficiency for cereal production.

    Because farm labor supervisors (FLSs) are responsible for ensuring safe work environments for thousands of workers, providing them with adequate knowledge is critical to preserving worker health. Yet a challenge to offering professional training to FLSs, many of whom are foreign-born and have received different levels of education in the US and abroad, is implementing a program that not only results in knowledge gains but meets the expectations of a diverse audience. By offering bilingual instruction on safety and compliance, the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) FLS Training program is helping to improve workplace conditions and professionalize the industry. A recent evaluation of the program combined participant observation and surveys to elicit knowledge and satisfaction levels from attendees of its fall 2012 trainings. Frequency distributions and dependent- and independent-means t-tests were used to measure and compare participant outcomes. The evaluation found that attendees rated the quality of their training experience as either high or very high and scored significantly better in posttraining knowledge tests than in pretraining knowledge tests across both languages. Nonetheless, attendees of the trainings delivered in English had significantly higher posttest scores than attendees of the trainings delivered in Spanish. As a result, the program has incorporated greater standardization of content delivery and staff development. Through assessment of its program components and educational outcomes, the program has documented its effectiveness and offers a replicable approach that can serve to improve the targeted outcomes of safety and health promotion in other states.

  1. Gravity Waves and Wind-Farm Efficiency in Neutral and Stable Conditions

    Allaerts, Dries; Meyers, Johan

    2018-02-01

    We use large-eddy simulations (LES) to investigate the impact of stable stratification on gravity-wave excitation and energy extraction in a large wind farm. To this end, the development of an equilibrium conventionally neutral boundary layer into a stable boundary layer over a period of 8 h is considered, using two different cooling rates. We find that turbulence decay has considerable influence on the energy extraction at the beginning of the boundary-layer transition, but afterwards, energy extraction is dominated by geometrical and jet effects induced by an inertial oscillation. It is further shown that the inertial oscillation enhances gravity-wave excitation. By comparing LES results with a simple one-dimensional model, we show that this is related to an interplay between wind-farm drag, variations in the Froude number and the dispersive effects of vertically-propagating gravity waves. We further find that the pressure gradients induced by gravity waves lead to significant upstream flow deceleration, reducing the average turbine output compared to a turbine in isolated operation. This leads us to the definition of a non-local wind-farm efficiency, next to a more standard wind-farm wake efficiency, and we show that both can be of the same order of magnitude. Finally, an energy flux analysis is performed to further elucidate the effect of gravity waves on the flow in the wind farm.

  2. Is the Modern High Potential Dairy Cow Suitable for Organic Farming Conditions?

    Directory of Open Access Journals (Sweden)

    Harðarson Grétar H

    2002-03-01

    Full Text Available It is not acceptable to compromise animal welfare in any system of farming. Feeding should be aimed at meeting the nutritional requirements at the various stages of production. This paper deals with the detrimental effects that organic, extensive or low input farming systems may have on the energy status in early lactation of the high potential dairy cow. Bovine ketosis is the most important disease resulting from insufficient energy intake in early lactation. It is also important to realize that ketosis is a part of the so-called periparturient disease complex, which includes milk fever, mastitis, retained placenta, endometritis and poor fertility also. All these diseases are interrelated and reflect to a large extent the nutritional status of the animal. If organic dairy farming is to be successful the breeding programmes have to divert from selection for high yields as a main goal, to more emphasis on a flatter lactation curve, less production diseases and longevity.

    Full Text Available Left displaced abomasum (LDA is a severe metabolic disease of cattle with a strong negative impact on production efficiency of dairy farms. Metabolic and inflammatory alterations associated with this disease have been reported in earlier studies, conducted mostly in large dairy farms. This research aimed to: (1 evaluate metabolic and inflammatory responses in dairy cows affected by LDA in small-scaled dairy farms; and (2 establish an Animals 2015, 5 1022 association between lactation number and milk production with the outcome of metabolic variables. The cows with LDA had lower serum calcium (Ca, but greater concentrations of non-esterified fatty acids (NEFA and beta-hydroxy-butyrate (BHBA, in particular when lactation number was >2. Cows with LDA showed elevated levels of aspartate aminotransferase, glutamate dehydrogenase, and serum amyloid A (SAA, regardless of lactation number. In addition, this study revealed strong associations between milk yield and the alteration of metabolic profile but not with inflammation in the sick cows. Results indicate metabolic alterations, liver damage, and inflammation in LDA cows kept under small-scale farm conditions. Furthermore, the data suggest exacerbation of metabolic profile and Ca metabolism but not of inflammation and liver health with increasing lactation number and milk yield in cows affected by LDA.

    Full Text Available A number of mutilating procedures, such as dehorning in cattle and goats and beak trimming in laying hens, are common in farm animal husbandry systems in an attempt to prevent or solve problems, such as injuries from horns or feather pecking. These procedures and other practices, such as early maternal separation, overcrowding, and barren housing conditions, raise concerns about animal welfare. Efforts to ensure or improve animal welfare involve adapting the animal to its environment, i.e., by selective breeding (e.g., by selecting “robust” animals adapting the environment to the animal (e.g., by developing social housing systems in which aggressive encounters are reduced to a minimum, or both. We propose adapting the environment to the animals by improving management practices and housing conditions, and by abandoning mutilating procedures. This approach requires the active involvement of all stakeholders: veterinarians and animal scientists, the industrial farming sector, the food processing and supply chain, and consumers of animal-derived products. Although scientific evidence about the welfare effects of current practices in farming such as mutilating procedures, management practices, and housing conditions is steadily growing, the gain in knowledge needs a boost through more scientific research. Considering the huge number of animals whose welfare is affected, all possible effort must be made to improve their welfare as quickly as possible in order to ban welfare-compromising procedures and practices as soon as possible.

    Full Text Available Farming of native carnivore fish species has drawn attention due to their promising use in aquaculture. Among these species, tucunaré of the genus Cichla stand out, them being of high economical interest for sport fishing and Amazon's industry of ornamental fish. The present study describes the weight-length relationship (WLR, relative condition factor (Kn, red blood cell parameters, thrombocytes and leukocytes count of Cichla temensis Humboldt, 1821, farmed in central Amazon. Fish that underwent food training during fingerling culture received extruded ration containing 45% of crude protein during fattening, and had Kn with values from 0.925-1.199, which indicated good health condition during the culture. The equation obtained from the WLR was W = 0.0073Lt3.1435, indicating an isometric growth, which is the desirable for fish of fish farm. Red blood cell counts, total thrombocyte and leukocyte counts, hematocrit, hemoglobin concentration, mean corpuscular volume (MCV, concentration of mean corpuscular hemoglobin (MCHC, lymphocytes, monocytes and neutrophils had intra-specific variation. A significant (p<0.001 positive correlation of the red blood cells number with the hemoglobin concentration and hematocrit was found. These are the first sets of blood parameters for C. temensis and could be used as reference for comparison in further studies to evaluate the health status of this fish in different environments, because assessment of these parameters may be used as quick tool for diagnosing diseases, stress and malnutrition.

The methods of treatment are mainly realized by cultivation of green manure crop and fertilizing by organic fertilizers. The aim of the long-term experiment was to evaluate the effect of different localities and different organic fertilizers on crop yield in organic farming.

Green manure + renewable external sources + auxiliary substances, 5. Green manure + farm fertilizers, 6. Green manure + farm fertilizers + auxiliary substances. The experiment started by sowing of winter wheat so green manure crop was not grown in the first experimental year. The highest yield of winter wheat grain coming from the first year of the experiment was observed on the variant with renewable external sources (digestate. Average grain yield on this variant was about 7.12 t/ha (up to 0.74 t/ha increased than the unfertilized control. Average yield of potatoes from the second year of the experiment was the highest after combination with green manure + renewable external sources (compost + digestate + auxiliary substances. This variant achieved yield about 34.08 t/ha, which is increased by 9.35 t/ha compared to the control variant. Results from this two-year experiment showed that the most suitable combination of fertilization with or without green manure crop is compost + digestate. These results were probably caused by higher content of nitrogen in organic fertilizers (compost + digestate used in this variant compared to other variants. Statistical difference of achieved yields was observed between each experimental station in both experimental years.

    During the last decades the shipping industry has undergone rapid technical developments and experienced hard economic conditions and increased striving for profitability. This has led to reduced staffing and changes in task performance, which has been reported to increase workload for the remaining seafarers. The working conditions on board have a number of distinct and in many ways unique characteristics, which makes the job demands and resources for seafarers unique in several ways. The purpose of this study was to assess how engine room staff perceives how these major technical and organizational changes in the shipping industry have affected job demands as well as resources. The study compiled individual interviews and focus groups interviews with engine crew members where they were asked to elaborate on the psychosocial work environment and the major changes in the working conditions on board. Engine crew describes a work situation where they feel a lack of resources. The content of the work has changed, staffing has been reduced, new tasks are being added but the organization of the crew and the design of the work place remains unaltered.

    The aim of the investigation was to analyse physico-chemical characteristics, nutrient composition and consumer acceptability of wheat varieties grown under organic and inorganic farming conditions. The seeds of five varieties of wheat (C-306, WH-283, WH-711, WH-896 and WH-912) grown under organic and inorganic farming conditions were ground in a Junior Mill to pass through 60-mesh sieves and were stored in air-tight containers until use. Standard methods were used to estimate the physico-chemical characteristics and nutrient composition. Consumer acceptability was studied by carrying out the organoleptic evaluation of wheat chapatis, a common item in diets of the Indian population. The results of study revealed that inorganically grown wheat varieties had significantly higher 1,000-grain weight and more grain hardness as compared with organically grown wheat varieties, and a non-significant difference was observed in their gluten content, water absorption capacity and hydration capacity. On average, wheat varieties grown under inorganic conditions contained significantly higher protein and crude fibre content as compared with varieties grown under organic conditions. WH-711 variety had maximum protein content. Protein fractions (i.e. albumin, globulin, prolamin and glutelin) were significantly higher in varieties grown under inorganic conditions than those of varieties grown under organic conditions. The variety WH-711 had the highest total soluble sugars and variety WH-912 had the highest starch content. Phytic acid and polyphenol contents were significantly higher in inorganically grown wheat varieties as compared with organically grown wheat varieties. The wheat varieties grown under organic conditions had significantly higher protein and starch digestibility than the wheat grown under inorganic conditions. The data revealed that there were significant differences in total calcium and phosphorus contents of wheat varieties grown under organic and inorganic

    Today, we can see a trend toward increased psychosocial strain at work among home-care managers and staff. The aim of this study is to describe home care managers' views on their own psychosocial working conditions and on how to promote workplace health and safety in a municipality in northern Sweden. A mixed-methods design was used, including questionnaire and qualitative focus group data. The qualitative data were analyzed by manifest content analysis. The results indicate that most managers perceived increased variety in work and opportunities for development at work, but at the same time increased demands. The managers suggested that workplace health and safety could be improved by risk assessment and improved communication, a clear communication chain by a real as well as a virtual platform for communication. In summary, workplace health and safety could be improved by risk assessments and by a physical as well as a virtual platform for communication.

  17. Attitudes of livestock farmers and sensitivity of livestock farming systems to drought conditions in the French Alps

    Full Text Available Livestock farming systems in the French Alps are particularly exposed to the predicted climate change and most of them have already experienced periods of drought since the beginning of the 2000s. Faced with this risk, livestock farmers have put in place a certain number of measures and envisage introducing others in the future. For the present study, surveys were conducted among livestock farmers to identify these measures and analyses were carried out to characterise the attitudes of livestock farmers to drought conditions and to evaluate changes in the sensitivity of their livestock farming systems. With the exception of those farms with extensive irrigated areas, all the farms are seeking solutions to deal with the risks arising from droughts. One solution is to purchase fodder to compensate for the decrease in the harvests that normally provide animal feed in the winter; the amounts purchased vary with the length of wintering required. For the grazing periods, the high mountain livestock breeders and the dairy systems of the Northern Alps rely above all on extending and over-sizing the pasture areas in relation to the needs of the herds. The livestock farms of the Southern Alps also rely on the diversity of vegetation areas and a certain flexibility in the practices used to adapt to conditions experienced during the year. A succession of dry years could result in more radical breakdowns in the livestock systems. It should also be remembered that climate change is only one of the factors influencing the types of changes taking place on farms.Les systèmes d'élevage des Alpes françaises sont fortement exposés au changement climatique annoncé et la plupart subissent déjà des épisodes de sécheresse depuis le début des années 2000. Face à ces aléas, les éleveurs ont mis en œuvre un certain nombre de leviers et envisagent d'en activer d'autres à l'avenir. Des enquêtes en exploitation ont permis d’identifier ces leviers. Leur

    The specific problems associated with the work on board within the merchant fleet are well known and have over the years been a topic of discussion. The work conditions in the engine room (ER) are demanding due to, e.g. the thermal climate, noise and awkward working postures. The work in the engine control room (ECR) has over recent years undergone major changes, mainly due to the introduction of computers on board. In order to capture the impact these changes had implied, and also to investigate how the work situation has developed, a total of 20 engine officers and engine ratings were interviewed. The interviews were semi-structured and Grounded Theory was used for the data analysis. The aim of the present study was to describe how the engine crew perceive their work situation and working environment on board. Further, the aim was to identify areas for improvements which the engine crew consider especially important for a safe and effective work environment. The result of the study shows that the design of the ECR and ER is crucial for how different tasks are performed. Design which does not support operational procedures and how tasks are performed risk inducing inappropriate behaviour as the crew members' are compelled to find alternative ways to perform their tasks in order to get the job done. These types of behaviour can induce an increased risk of exposure to hazardous substances and the engine crew members becoming injured. Copyright © 2010 Elsevier Ltd and The Ergonomics Society.

    The main goal of this study was to create a database that ultimately serves further studies on riparian vegetation and flow response guilds in the boreal region and on transferability of results across different regions. To achieve this aim, we compiled traits for all woody riparian species in northern Sweden which, directly or indirectly, underlie their responses to hydrological and hydraulic conditions, between October 2012 and April 2015. Consulted sources of information were diverse, ranging from scientific to informative and whose accuracy might or might not be verified. They were focused on particular or several traits and species from concrete areas to a worldwide perspective. Sources were characterized by different degrees of accessibility and showed a wide variety of descriptions, categorical and ordinal classifications, and numerical information for each trait. Our effort was to synthesize information for each trait from all sources into the common frame of our own database, following own defined criteria so that comparisons between species are congruent. Therefore, this data set is unique in that it comprehensively combines and homogenizes morphological, phenological, reproductive, and ecological data for 59 woody, riparian, boreal species and from 118 sources of information, that would otherwise be scattered and hardly available. © 2016 by the Ecological Society of America.

    To test the hypothesis that certain individual, environmental and lifestyle factors are positively associated with beneficial health investment behaviours and oral/periodontal health among adolescents. Five hundred and six randomly selected 19-year old subjects living in two different areas (Fyrbodal and Skaraborg) in the county council of Västra Götaland, Sweden participated in a clinical examination and answered questionnaires covering psycho-social and health behavioural issues. Two oral-health models were estimated with gingivitis score as an objective and self-perceived oral health as a subjective indicator. Three health- investment behaviour models were designed with indicators directly related to oral health and two with indicators related to general health as well. The explanatory variables included gender, upper secondary education programme, native country, living area, general self-efficacy and parents' education level. In the objective oral-health model, theoretical studies and living in the Skaraborg area were both positively associated with a lower gingivitis score. For the subjective oral-health indicator, none of the explanatory variables showed statistical significance. In the investment-behaviour model with 'tooth-brushing ≥ 2 times daily' as a health indicator, female gender and theoretical studies showed statistically significant associations. With the indicators 'no/few missed dental appointments', 'no tobacco use' and 'weekly exercise', theoretical studies were statistically significant and positively associated. In the investment model with 'perceived oral health care attention' as an indicator, a high score of general self-efficacy was significantly associated with the feeling of taking good care of the teeth. Individual, environmental and lifestyle factors are associated with young individuals' oral health investment behaviours and gingival health conditions.

    In a first part, this report presents some characteristics and key aspects of the anaerobic digestion process. It highlights its environmental benefits, notices that energy production from breeding effluents is not optimal, that this energy is easily exportable, but that this process does not process nitrogen and phosphorus surpluses. It gives an overview of the status of practices in France, in Germany where incentive policies have promoted the development of on-farm anaerobic digestion for many years, in Denmark, in Sweden and in Switzerland where the gas feeds directly the network. It presents the legal and regulatory framework for installations classified with respect to the protection of the environment, for the digestate approval and standardization, for the connection to the electric network, for bio-gas transportation and injection in networks, and for taxes. It proposes an economic analysis: investments and scale effects, cogeneration and electricity sale, perspectives for biogas direct sale, waste and digestate value, and so on. It proposes a review of research and development works in this domain, and finally addresses some issues of economic and regional development

    The aim of the experiment was to study the effect of feeding system on meat quality characteristics of Small East African (SEA) goats and their crosses with Norwegian (SEA×N) goats finished under small scale farming conditions. Twenty four castrated goats at the age of 18 months with live body weight of 16.7±0.54 kg from each breed (SEA and SEA×N) were distributed in a completely randomized design in a 2×3 factorial arrangement (two breed, and three dietary treatments). The dietary treatments were; no access to concentrate (T0), 66% access to ad libitum concentrate allowance (T66) and 100% access to ad libitum concentrate allowance with 20% refusal (T100) and the experimental period was for 84 days. In addition, all goats were allowed to graze for 2 hours daily and later fed grass hay on ad libitum basis. Daily feed intakes were recorded for all 84-days of experiment after which the animals were slaughtered. Feed intake of T100 animals was 536 g/d, which was 183 g/d higher than that of T66 group. Supplemented goats had significantly (pconversion efficiency. The SEA had higher (p0.05) for dressing percentage and carcass conformation among supplemented goats except fatness score, total fat depots and carcass fat which increased (pgoats fed concentrate declined rapidly and reached below 6 at 6 h post-mortem but temperature remained at 28°C. Cooking loss and meat tenderness improved (pgoats and their crosses with Norwegian breeds finished under small scale farming conditions in rural areas. Therefore, concentrate supplementation of goats of both breeds improves meat quality attributes.

    In order to gain more knowledge on the stress responses of gilhead seabream (Sparus aurata) under extreme conditions, this study investigated the functional properties of the hemoglobin system and globin gene expression under hypoxia and low salinity. The oxygen affinity for the two hemoglobin components present inside the S. aurata erythrocyte was practically identical as was the influence of protons and organic phosphates (Root effect). The quantification of S. aurata hemoglobin fractions performed by HPLC and the data on gene expression of globin chains assayed by PCR indicate that under hypoxia and low salinity there is a change in the ratio between the two different hemoglobin components. The result indicating that the distinct hemoglobins present in S. aurata erythrocyte have almost identical functional properties, does not explain the adaptive response (expression change) following exposure of the animal to hypoxia or low salinity on the basis of their function as oxygen transporter. We hypothesize that other parallel biological functions that the hemoglobin molecule is known to display within the erythrocyte are involved in adaptive molecular mechanisms. The autoxidation-reduction cycle of hemoglobin could be involved in the response to particular living conditions

    The current review seeks to highlight the concerns that have been raised on pre-slaughter stress, contributing factors and its consequent effects on cattle behavioural responses and the quality of beef; inter-linking the activities involved from birth to slaughter. Such information is crucial in light of the consumer concerns on overall animal welfare, quality of meat and food security. Slaughter animals are exposed to different conditions during production and transportation to abattoirs on a daily basis. However; the majority of studies that have been done previously singled out different environments in the meat production chain, while conclusions have been made that the welfare of slaughter animals and the quality of meat harvested from them is dependent on the whole chain. Behaviour is a critical component used to evaluate the animals’ wellbeing and it has been reported to have an effect on product quality. Apart from the influence of on-farm, transportation and abattoir conditions, the genetic background of the animal also affects how it perceives and responds to certain encounters. Stress activates the animals’ hypothalamic-pituitary-adrenal activity, triggering release of various stress hormones such as catecholamines and cortisol, thus glycogen depletion prior slaughter, elevated ultimate pH and poor muscle-meat conversion. Pre-slaughter stress sometimes results to cattle attaining bruises, resulting to the affected parts of the carcass being trimmed and condemned for human consumption, downgrading of the carcass and thus profit losses.

    The stochastic behaviors of rainfall pose serious limitations for sustained and profitable crop production in rainfed areas; farmers hesitate to apply fertilizers when they are not sure about rainfall. In view of these limitations a research study was conducted for three years (2003-2006) at field station of Water Resources Research Institute (WRRI), National Agricultural Research Centre(NARC), Islamabad to examine the effects of supplemental irrigation (SI) on wheat production and water use efficiency (WUE). Irrigation treatments employed under the experiment were: i) Rainfed without irrigation and fertilizer application (I/sub 0/); ii) SI of 25 mm was applied to non-fertilizer field at 75% management allowed deficit (MAD)(I/sub 1/); iii) Rainfed with fertilizer application at sowing time (I/sub 2/); and iv) SI of 25 mm was applied at 75% MAD and at the time of fertilizer application as top dressing (I/sub 3/). Supplemental irrigation increased the crop yield during the years 2003-2006 under both fertilizer and non-fertilizer conditions. Increased in grain yield under non-fertilizer conditions (I/sub 1/) ranges between 770-980 kg/ha, which is 27 to 48% higher than the rainfed yield (I/sub 0/). Supplemental irrigation and split application of fertilizer (treatment I/sub 3/) increased in grain yield within the range of 1000-1350 kg/ha, which is 27-49% higher than yield under treatment I/sub 2/. Whereas, due to synergetic effect of supplemental irrigation and fertilizer application, increased in grain yield ranges between 1550-2030 kg/ha, which is 49% to 100% higher than the rainfed and non-fertilizer field. WUE was calculated for rain (WUE/sub r/) for total water (grass: previous soil water storage + rain + irrigation) (WUE/sub g/), for SI water only (WUE/sub si/) and for synergetic effect (SI water + fertilizer application) (WUE/sub sis/) Water use efficiencies namely the WUE/sub r/, WUE/sub g/ and WUE/sub si/ during the period of three years under non fertilizer

    2018-01-01

    Full Text Available Operation and maintenance costs are a major contributor to the Levelized Cost of Energy for electricity produced by offshore wind and can be significantly reduced if existing corrective actions are performed as efficiently as possible and if future corrective actions are avoided by performing sufficient preventive actions. This paper presents an applied and generic diagnostic model for fault detection and condition based maintenance of offshore wind components. The diagnostic model is based on two probabilistic matrices; first, a confidence matrix, representing the probability of detection using each fault detection method, and second, a diagnosis matrix, representing the individual outcome of each fault detection method. Once the confidence and diagnosis matrices of a component are defined, the individual diagnoses of each fault detection method are combined into a final verdict on the fault state of that component. Furthermore, this paper introduces a Bayesian updating model based on observations collected by inspections to decrease the uncertainty of initial confidence matrix. The framework and implementation of the presented diagnostic model are further explained within a case study for a wind turbine component based on vibration, temperature, and oil particle fault detection methods. The last part of the paper will have a discussion of the case study results and present conclusions.

The usual hematological indices values, determinate in the end of the experiments evidenced the fact that, in two variant taken under study both the levels of Hb, Ht and the number of red blood cells behave the oscillations between normal limits for C1+ cyprinids, with notable differences between three species. In common carp, the values of all three indices from the research variant maintained with 11-12% lower than in the control variant, to the antipodes being bighead carp, in which all indices have in variant of research the bigger values with 11-32% than the control. This suggests that in common carp, respiratory functions accommodation is canalized less on quantitative line, rising on Hb quantity and more on qualitative line, the Hb capacity rise to bound the oxygen, and in bighead carp the tendency is reverse. In silver carp, the Hb values and the erythrocytes number are less with 8-23% in variant of research than to the control, while the hematocryte is with 13% elder than to the control variant, in correlation with the MCV values, which are with 43% bigger than to the lot of research.

    Full Text Available The polychaete Capitella sp. A, collected in a NW Mediterranean fish farm (Les Cases d’Alcanar, Tarragona, Spain, was cultured for the first time under experimental conditions with different organically enriched sediments to study the differences in development and growth. The species proved to be dioecious and had lecithotrophic development. Sizes of individuals and duration of the developmental stages varied widely, as in most known species of Capitella. In organically enriched sediments, the juveniles were seen one day after hatching and immature females (i.e. with yellow ovaries after 52 days. Females may reach maturity (i.e. show white intra-coelomic oocytes at about 64 days old, and the species had a life span of 167 days. According to its development, Capitella sp. A differs from all known lecithotrophic species of the genus. The results also proved that organically enrichment enhanced growth and survival, whereas lowering food can cause morphological alterations such as reduced size in male genital spines.

    Full Text Available Recent years have seen significant developments in the ability to continuously propagate organoids derived from intestinal crypts. These advancements have been applied to mouse and human samples providing models for gastrointestinal tissue development and disease. We adapt these methods for the propagation of intestinal organoids (enteroids from various large farm and small companion (LF/SC animals, including cat, dog, cow, horse, pig, sheep and chicken. We show that LF/SC enteroids propagate and expand in L-WRN conditioned media containing signaling factors Wnt3a, R-spondin-3, and Noggin (WRN. Multiple successful isolations were achieved for each species, and the growth of LF/SC enteroids was maintained to high passage number. LF/SC enteroids expressed crypt stem cell marker LGR5 and low levels of mesenchymal marker VIM. Labeling with EdU also showed distinct regions of cell proliferation within the enteroids marking crypt-like regions. The ability to grow and maintain LF/SC enteroid cell lines provides additional models for the study of gastrointestinal developmental biology as well as platforms for the study of host-pathogen interactions between intestinal cells and zoonotic enteric pathogens of medical importance.

In this study, we assessed the potential for wine production in Sweden. The estimated annual costs varied from €15.1/per L for production of 1800 L wine per ha to €41.9 for 525 L per ha. For an annual production of 1800 L per ha potentially achieved in an established vineyard, the capital requirement is €730,000. It would take 6 years for the investment to be paid off if the wine was sold for €37.5 per L. The high production costs mean that the only viable option for success is to orientate production towards the exclusive upper segment.Keywords: cold climate conditions, wine production costs, wine quality

    Among Swedish pregnant teenage girls it is unusual to continue pregnancy and to choose to have a baby. Swedish teenage mothers can therefore be expected to differ from adult mothers, at a group level. The aim of this study was to describe and compare teenage mothers who were giving birth in hospital with adult mothers as to sociodemographic background, perception of health and social support. A descriptive comparative study was conducted over one year, in a county in south-western Sweden, which comprised a group of all teenage mothers aged 15-19, who gave birth at hospital (study group n=97) and the same number of adult mothers aged 25-29, matched for parity and birth of a baby closest to the index mother (reference group). Both groups answered a questionnaire regarding sociodemographic variables, lifestyle, health, self-esteem, depressive symptoms, and support. Information on the mothers' pregnancy and delivery was obtained from their maternal health and delivery charts. Teenage mothers had more often been exposed to a difficult family situation, had more often experienced school failure than adult mothers, and showed health-risk behavior. Teenage mothers perceived less support, had lower self-esteem, and more depressive symptoms than adult mothers. Teenage mothers differed from adult mothers regarding family situation and health behavior as well as perception of support, self-esteem, and depressive symptoms, which may negatively influence their ability to cope with parenthood. Efforts should be made early in pregnancy to meet both health and support needs of teenage mothers.

  20. Barriers to Business Model Innovation in Swedish Agriculture

    2015-02-01

    Full Text Available Swedish agricultural companies, especially small farms, are struggling to be profitable in difficult economic times. It is a challenge for Swedish farmers to compete with imported products on prices. The agricultural industry, however, supports the view that through business model innovation, farms can increase their competitive advantage. This paper identifies and describes some of the barriers Swedish small farms encounter when they consider business model innovation. A qualitative approach is used in the study. Agriculture business consultants were interviewed. In a focus group led by the researchers, farmers discussed business model innovation, including the exogenous and endogenous barriers to such innovation. The paper concludes many barriers exist when farmers consider innovation of agricultural business models. Some barriers are caused by human factors, such as individuals’ attitudes, histories, and traditions. Other barriers are more contextual in nature and relate to a particular industry or company setting. Still other barriers, such as government regulations, value chain position, and weather, are more abstract. All barriers, however, merit attention when Swedish agricultural companies develop new business models.

For the farmer, the ability to predict energy balance for individual cows on-farm without having to measure feed intake would......Precise energy balance estimates for individual cows are of great importance to health, reproduction and feed management. Energy balance is usually calculated as energy input minus output (EBalinout), requiring measurements of feed intake and energy output sources (milk, maintenance, activity......, growth and pregnancy). Except milk yield, direct measurements of these are difficult to obtain in practice, and estimates involve considerable error sources, so limiting on-farm use. Alternatively, energy balance can be estimated from body reserve changes (EBalbody) using body weight (BW) and body...

    Full Text Available Purpose. To analyze the results of morphometric measurements and dates of aquaculture-biological characteristics of the young-of-the-year and age-1+ rainbow trout reared under industrial technology at instable conditions of the fish farm “Sloboda-Banyliv”. Methodology. The study has been performed at the industrial fish farm “Sloboda-Banyliv”, Chernivtsi region. The materials for the study were young-of-the-year and age-1+ rainbow trout obtained from the eggs of autumn-spawning form rainbow trout. The young-of-the-year were reared in a 216 m2 tank with stocking density of 255 ind./m2, age-1+ fish were reared in 108 m2 tank with a stocking density of 33 ind./m2 according to generally accepted methods in trout culture. Morphometric measurements of fish were performed according to I.F. Pravdin. Statistical processing of data was carried out in Microsoft Office Excel (2003. The analysis of values was done in the system of absolute values. The analyzed criteria of the measured parameters were their mean values and standard errors (M±m, deviation (σ, variability coefficient (Cv. Fish were fed with the artificial feed with high protein content manufactured by “Biomar” (Denmark. Findings. The studies on rainbow trout rearing under industrial conditions showed that fish body proportions did not change with age, however, the length of their fins decreased. The slenderness coefficient in age-1+ fish decreased insignificantly that is typical with increasing body depth. Despite instable rearing conditions, both young-of-the-year and age-1+ fish were characterized by moderate growth rate and high feed-conversion efficiency. Originality. For the first time, in conditions of Ukraine, a study on the formation of rainbow trout brood stocks in a fish farm with instable rearing conditions was performed with the use of the analysis of phenotypical and productive features.

Cross-sectional data from a community household sample (n = 591 describe the alcohol use patterns of adult males and females, and farm workers vs. others. Data reveal that men were more likely to be current drinkers than women, 75.1% vs. 65.8% (p = 0.033; farm laborers were more likely to be current drinkers than individuals in other occupations 83.1% vs. 66.8% (p = 0.004.

The legacy of “Dop” contributes to current risky drinking behaviors. Farm owners or managers were interviewed on 11 farms, they described working conditions on their farms and how the legacy of “Dop” is reflected in the current use of alcohol by their workers. “Dop” was given to farm workers in the past on six of the 11 farms, but was discontinued for different reasons. There is zero tolerance for coming to work intoxicated; farm owners encourage responsible use of alcohol and assist farm workers in getting help for alcohol problems when necessary. The farm owners report some positive initiatives, were ahead of the movement to provide meaningful wages, and provide other important amenities. Further research is needed to assess whether progressive practices on some farms will reduce harmful alcohol use.

    Early life conditions play an important role in determining adult body size. In particular, childhood malnutrition and disease can elicit growth delays and affect adult body size if severe or prolonged enough. In the earliest stages of farming, skeletal growth impairment and small adult body size are often documented relative to hunter-gatherer groups, though this pattern is regionally variable. In Central/Southeast Europe, it is unclear how early life stress, growth history, and adult body size were impacted by the introduction of agriculture and ensuing long-term demographic, social, and behavioral change. The current study assesses this impact through the reconstruction and analysis of mean stature, body mass, limb proportion indices, and sexual dimorphism among 407 skeletally mature men and women from foraging and farming populations spanning the Late Mesolithic through Early Medieval periods in Central/Southeast Europe (~7100 calBC to 850 AD). Results document significantly reduced mean stature, body mass, and crural index in Neolithic agriculturalists relative both to Late Mesolithic hunter-gatherer-fishers and to later farming populations. This indication of relative growth impairment in the Neolithic, particularly among women, is supported by existing evidence of high developmental stress, intensive physical activity, and variable access to animal protein in these early agricultural populations. Among subsequent agriculturalists, temporal increases in mean stature, body mass, and crural index were more pronounced among Central European women, driving declines in the magnitude of sexual dimorphism through time. Overall, results suggest that the transition to agriculture in Central/Southeast Europe was challenging for early farming populations, but was followed by gradual amelioration across thousands of years, particularly among Central European women. This sex difference may be indicative, in part, of greater temporal variation in the social status afforded

    Occupations and psychosocial working conditions have rarely been investigated as predictors of disability pension in population-based samples. This study investigated how occupational groups and psychosocial working conditions are associated with future disability pension due to musculoskeletal diagnoses, accounting for familial factors in the associations. A sample of 24,543 same-sex Swedish twin individuals was followed from 1993 to 2008 using nationwide registries. Baseline data on occupations were categorized into eight sector-defined occupational groups. These were further used to reflect psychosocial working conditions by applying the job strain scores of a Job Exposure Matrix. Cox proportional hazard ratios (HR) were estimated. During the 12-year (average) follow-up, 7% of the sample was granted disability pension due to musculoskeletal diagnoses. Workers in health care and social work; agriculture, forestry and fishing; transportation; production and mining; and the service and military work sectors were two to three times more likely to receive a disability pension than those in the administration and management sector. Each single unit decrease in job demands and each single unit increase in job control and social support significantly predicted disability pension. Individuals with high work strain or an active job had a lower hazard ratio of disability pension, whereas a passive job predicted a significantly higher hazard ratio. Accounting for familial confounding did not alter these results. Occupational groups and psychosocial working conditions seem to be independent of familial confounding, and hence represent risk factors for disability pension due to musculoskeletal diagnoses. This means that preventive measures in these sector-defined occupational groups and specific psychosocial working conditions might prevent disability pension due to musculoskeletal diagnoses.

  12. Toward a Satellite-Based System of Sugarcane Yield Estimation and Forecasting in Smallholder Farming Conditions: A Case Study on Reunion Island

    2014-07-01

    Full Text Available Estimating sugarcane biomass is difficult to achieve when working with highly variable spatial distributions of growing conditions, like on Reunion Island. We used a dataset of in-farm fields with contrasted climatic conditions and farming practices to compare three methods of yield estimation based on remote sensing: (1 an empirical relationship method with a growing season-integrated Normalized Difference Vegetation Index NDVI, (2 the Kumar-Monteith efficiency model, and (3 a forced-coupling method with a sugarcane crop model (MOSICAS and satellite-derived fraction of absorbed photosynthetically active radiation. These models were compared with the crop model alone and discussed to provide recommendations for a satellite-based system for the estimation of yield at the field scale. Results showed that the linear empirical model produced the best results (RMSE = 10.4 t∙ha−1. Because this method is also the simplest to set up and requires less input data, it appears that it is the most suitable for performing operational estimations and forecasts of sugarcane yield at the field scale. The main limitation is the acquisition of a minimum of five satellite images. The upcoming open-access Sentinel-2 Earth observation system should overcome this limitation because it will provide 10-m resolution satellite images with a 5-day frequency.

    Full Text Available Naked oats is varietal variation of oats, whose potential is necessary to examine for the various agricultural regions in Bulgaria. The objective of this experiment is to track down and to determine opportunities for growing Bulgarian naked oat variety "Mina", in ecological conditions of Sakar agricultural region. The surveys were carried out during the period 2009-2011 in experimental base for the Sakar mountain of ISSAPP "N. Pushkarov" Sofia. Under the too specific conditions of Sakar agricultural region and grown in organic farming the naked oats variety "Mina" shows good adaptability for growth and development. The vegetation period lasts 93-115 days. In the initial phases of its development the naked oats grew by 1.9 – 7.6 cm, in the phases of the active growing season grew by 8.3-12.3 cm. For the vegetation period the naked oats variety "Mina" grew by 64.9-74.2 cm

  16. Biomass and Swedish energy policy

    International Nuclear Information System (INIS)

    Johansson, Bengt

    2001-01-01

    The use of biomass in Sweden has increased by 44% between 1990 and 1999. In 1999 it was 85 TWh, equivalent to 14% of the total Swedish energy supply. The existence of large forest industry and district heating systems has been an essential condition for this expansion. The tax reform in 1991 seems, however, to have been the most important factor responsible for the rapid bioenergy expansion. Through this reform, the taxation of fossil fuels in district heating systems increased by approximately 30-160%, depending on fuel, whereas bioenergy remained untaxed. Industry is exempted from the energy tax and pays reduced carbon tax. No tax is levied on fossil fuels used for electricity production. Investment grants have existed for biomass-based electricity production but these grants have not been large enough to make biomass-based electricity production economically competitive in a period of falling electricity prices. Despite this, the biomass-based electricity production has increased slightly between 1990 and 1999. A new taxation system aiming at a removal of the tax difference between the industry, district heating and electricity sectors has recently been analysed by the Swedish government. One risk with such a system is that it reduces the competitiveness for biomass in district heating systems as it seems unlikely that the taxes on fossil fuels in the industry and electricity sectors will increase to a level much higher than in other countries. A new system, based on green certificates, for supporting electricity from renewable energy sources has also been proposed by the government.

    Nine adult Asiatic black bears (Ursus thibetanus) previously rescued from illegal bile farming in Vietnam were examined via abdominal ultrasound and exploratory laparoscopy for liver and gall bladder pathology. Three bears demonstrated notable gall bladder pathology, and minimally invasive cholecystectomies were performed using an open laparoscopic access approach, standard 10 to 12 mmHg carbon dioxide pneumoperitoneum and a four-port technique. A single bear required insertion of an additional 5 mm port and use of a flexible liver retractor due to the presence of extensive adhesions between the gall bladder and quadrate and left and right medial liver lobes. The cystic duct was dissected free and this and the cystic artery were ligated by means of extracorporeal tied Meltzer knot sutures. The gall bladder was dissected free of the liver by blunt and sharp dissection, aided by 3.8 MHz monopolar radiosurgery. Bears that have had open abdominal cholecystectomies are reported as taking four to six weeks before a return to normal activity postoperatively. In contrast, these bears demonstrated rapid unremarkable healing, and were allowed unrestricted access to outside enclosures to climb trees, swim and interact normally with other bears within seven days of surgery.

    Rates of disability pension are greatly increased among people with low education. This study examines the extent to which associations between education and disability pensions might be explained by differences in working conditions. Information on individuals at age 13 years was used to assess confounding of associations. Two nationally representative samples of men and women born in 1948 and 1953 in Sweden (22 889 participants in total) were linked to information from social insurance records on cause (musculoskeletal, psychiatric, and other) and date (from 1986-2008) of disability pension. Education data were obtained from administrative records. Occupation data were used for measurement of physical strain at work and job control. Data on paternal education, ambition to study, and intellectual performance were collected in school. Women were found to have higher rates of disability pension than men, regardless of diagnosis, whereas men had a steeper increase in disability pension by declining educational level. Adjustment of associations for paternal education, ambition to study, and intellectual performance at age 13 had a considerable attenuating effect, also when disability pension with a musculoskeletal diagnosis was the outcome. Despite this, high physical strain at work and low job control both contributed to explain the associations between low education and disability pensions in multivariable models. Working conditions seem to partly explain the increased rate of disability pension among men and women with lower education even though this association does reflect considerable selection effects based on factors already present in late childhood.

    The Organization of Estonian energetic economy is aimed at cutting the usage of oil, gas and coal and increasing the local resources firewood, oil-shale and peat for fuel. The resources of low-valued firewood-brushwood, fallen deadwood etc. are available during the following 10-15 years, but in the future the cultivation of energy forest (willow) plantations will be actual. During the last 20 years the Swedish scientists have been extensively studying the willow forest selection, cultivation and use in energetics and waste water purification systems. A Swedish-Estonian energy forest research project was started in 1993 between the Swedish Agricultural University on one hand and Toravere Observatory, Institute of Zoology and Botany, Estonian Academy of Sciences and Estonian Potato Processing Association on the other hand. In spring 5 willow plantations were established with the help of Swedish colleagues and obtained from Sweden 36000 willow cuttings. The aim of the project: a) To study experimentally and by means of mathematical modelling the biogeophysical aspects of growth and productivity of willow plantations in Sweden and Estonian climatological conditions. b) To study the possibility of using the willow plantations in waste waters purification. c) To study the economical efficiency of energy forest as an energy resource under the economic and environmental conditions of Estonia. d) To study the economic efficiency of willow plantations as a raw material for the basket industry in Estonia. e) To select the most productive and least vulnerable willow clones for practical application in energy plantations. During 1993 in all five plantations detailed analysis of soil properties has been carried out. In the plantation at Toravere Observatory phytometrical measurements were carried out - the growth of plant biomass leaf and stem area, vertical distribution of dry matter content, biomass and phyto area separately for leaves and stems has been performed.

    A study was conducted to evaluate the effect of bovine somatotropin (BST) supplementation in twelve lactating dairy cows maintained in cold environmental conditions. Six cows were injected daily with 25 mg of BST; the other six were injected with a control vehicle. Cows were maintained under standard dairy management during mid-winter for 30 days. Milk production was recorded twice daily, and blood samples were taken weekly. Animals were then transferred to environmentally controlled chambers and exposed to cycling thermoneutral (15° to 20° C) and cycling cold (-5° to +5° C) temperatures for 10 days in a split-reversal design. Milk production, feed and water intake, body weights and rectal temperatures were monitored. Blood samples were taken on days 1, 3, 5, 8 and 10 of each period and analyzed for plasma triiodothyronine (T3), thyroxine (T4), cortisol, insulin and prolactin. Under farm conditions, BST-treated cows produced 11% more milk than control-treated cows and in environmentally controlled chambers produced 17.4% more milk. No differences due to BST in feed or water intake, body weights or rectal temperatures were found under laboratory conditions. Plasma T3 and insulin increased due to BST treatment while no effect was found on cortisol, prolactin or T4. The results showed that the benefits of BST supplementation in lactating dairy cows were achieved under cold environmental conditions.

    After the introduction of a law prohibiting the start-up of any new nuclear power plant until the utility had shown that the waste produced by the plant could be taken care of in an absolutely safe way, the Swedish nuclear utilities in December 1976 embarked on the Nuclear Fuel Safety Project, which in November 1977 presented a first report, Handling of Spent Nuclear Fuel and Final Storage of Vitrified Waste (KBS-I), and in November 1978 a second report, Handling and Final Storage of Unreprocessed Spent Nuclear Fuel (KBS II). These summary reports were supported by 120 technical reports prepared by 450 experts. The project engaged 70 private and governmental institutions at a total cost of US $15 million. The KBS-I and KBS-II reports are summarized in this document, as are also continued waste research efforts carried out by KBS, SKBF, PRAV, ASEA and other Swedish organizations. The KBS reports describe all steps (except reprocessing) in handling chain from removal from a reactor of spent fuel elements until their radioactive waste products are finally disposed of, in canisters, in an underground granite depository. The KBS concept relies on engineered multibarrier systems in combination with final storage in thoroughly investigated stable geologic formations. This report also briefly describes other activities carried out by the nuclear industry, namely, the construction of a central storage facility for spent fuel elements (to be in operation by 1985), a repository for reactor waste (to be in operation by 1988), and an intermediate storage facility for vitrified high-level waste (to be in operation by 1990). The R and D activities are updated to September 1981.

    Full Text Available From all cereals the oats is the culture that due to dietary and healthy impact on the human body becomes more sought after in the market. The residual products of oats after harvesting the grain such as straw and chaff are sought after for animal feed. The aim of this research is to test the potential opportunities of the spring naked oats variety "Mina", Bulgarian selection, grown on the principles of organic farming. The research is carried out in real ecological environment under field conditions of Sakar agro-ecological region. In ecological environment and without using of pesticides and mineral fertilizers the vegetative development of the spring naked oats variety "Mina" passes normally. The duration of the vegetation period ranges from 93 to 115 days. For this period the oats grew by an average of 69.7 cm. Under the ecological conditions of Sakar agro-region average yields of grain are 1292.830 kg/ha, and the quantity of straw is 1515.500 kg/ha. The yields of grain of spring naked oat variety "Mina" grown in ecological conditions are lower compared to the average yields of oats in the country for the same period with 452.50 kg/ha. This difference is not alarming considering the fact that the production of this variety oats is ecological clean and there is market demand for dietetic foods.

    Antimicrobial resistance is an increasing problem and reducing AM use is critical in limiting its severity. The underlying causes of antimicrobial use at pig farm level must be understood to select effective reduction measures. We previously showed that antimicrobial use on Swedish pig farms is comparatively low but varies between farms, although few farms are high users. In the present survey of a convenience sample of 60 farrow-to-finish herds in Sweden, we investigated farmers' attitudes to antimicrobials and the influence of information provided by veterinarians about antimicrobial resistance. Farm characteristics were also recorded. We had previously quantified antimicrobial use for different age categories of pigs during one year, as well as external and internal biosecurity. Risk factors based on hypothetical causal associations between these and calculated treatment incidence (TI) for the different age categories were assessed here in a linear regression model. There were no significant associations between biosecurity and TI for any pig age category. Increasing farmer age was associated with higher TI for suckling piglets and fatteners. For suckling piglets, the age group with the highest frequency of treatment, TI was also significantly associated with farmer and education of the staff, where female farmers, and university educated staff was associated with a higher TI. Larger farms were associated with a higher TI in fatteners. In the investigated Swedish pig farms, factors that influenced antimicrobial usage were more related to characteristics of the individual farmer and his/her staff than to biosecurity level, other management factors or farmers' attitudes to antimicrobials.

    The incidence of hip fracture in Sweden is substantially lower in immigrants than in the population born in Sweden. Thus, the use of a FRAX® model in immigrants overestimates the risk of fracture, and the use of country of origin-specific models may be more appropriate. Age-specific fracture and mortality rates vary between countries so that FRAX tools are country-specific. In the case of immigrants, it is not known whether the model for the original or the new country is most appropriate. The aim of this study was to compare the incidence of hip fractures in foreign-born and Swedish-born individuals residing in Sweden. We studied the incidence of hip fracture in all men and women aged 50 years or more in Sweden between 1987 and 2002. The population comprised 2.8 million Swedish-born and 270,000 foreign-born individuals. Incident hip fractures occurred in 239,842 Swedish-born and 12,563 foreign-born individuals. The hip fracture incidence rose with age for both groups and was higher for women than men amongst both Swedish-born and foreign-born individuals. The hip fracture incidence for the Swedish-born cohort was approximately twice that of immigrants. For example, at the age of 70 years, the annual hip fracture incidence (per 100,000) was 450 (95 % CI 446-454) for a Swedish-born woman and 239 (95 % CI 223-257) for a foreign-born woman at the time of immigration. The hip fracture incidence rose slowly with time from immigration (0.6 % per annum, 95 % CI 0.5-0.8 %) but remained significantly lower than for Swedish-born individuals even after 40 years of residence. The incidence of hip fracture in Sweden is substantially lower in immigrants than in the population native to Sweden. Although there was a small rise in age- and sex-specific incidence after immigration, the incidence remained markedly lower than that observed in Swedish-born individuals. Thus, the use of a FRAX model for Sweden will overestimate the risk of fracture for foreign-born individuals living

    Full Text Available Obstetric thromboprophylaxis is difficult. Since 10 years Swedish obstetricians have used a combined risk estimation model and recommendations concerning to whom, at what dose, when, and for how long thromboprophylaxis is to be administrated based on a weighted risk score. In this paper we describe the background and validation of the Swedish guidelines for obstetric thromboprophylaxis in women with moderate-high risk of VTE, that is, at similar or higher risk as the antepartum risk among women with history of thrombosis. The risk score is based on major risk factors (i.e., 5-fold increased risk of thromboembolism. We present data on the efficacy of the model, the cost-effectiveness, and the lifestyle advice that is given. We believe that the Swedish guidelines for obstetric thromboprophylaxis aid clinicians in providing women at increased risk of VTE with effective and appropriate thromboprophylaxis, thus avoiding both over- and under-treatment.

    This guide has been developed by Nordisk Vindkraft in co-operation with Energimyndigheten (the Swedish Energy Agency). The main purpose is to raise the attention to work environment matters when developing, constructing and operating large-scale wind farms in the northern parts of Sweden. The Swedish wind industry is relatively young. Work Environment Management and legal awareness has been identified by the Swedish Government as one crucial factor for ensuring sound and rapid development of the industry. Havsnaes is to date the largest onshore wind farm in Sweden. Whilst developing this project, Nordisk Vindkraft has gained extensive experience and developed a profound understanding of the prerequisites for the Swedish large-scale wind industry. The wind farm's size, complexity and geographical location near Stroemsund in Jaemtland qualify the project as an excellent pilot study. Preventing accidents and ill-health largely depends on your knowledge, competence and the resources you are able and willing to spend. The key for success is a pro-active approach. During the Havsnaes project, Nordisk Vindkraft has spent considerable amount of time and effort on the management of Work Environment. We hope our gained experience will be beneficial for our industry as a whole.

  4. Classification of real farm conditions Iberian pigs according to the feeding regime with multivariate models developed by using fatty acids composition or NIR spectral data

    Full Text Available Multivariate Classification models to classify real farm conditions Iberian pigs, according to the feeding regime were developed by using fatty acids composition or NIR spectral data of liquid fat samples. A total of 121 subcutaneous fat samples were taken from Iberian pigs carcasses belonging to 5 batches reared under different feeding systems. Once the liquid sample was extracted from each subcutaneous fat sample, it was determined the percentage of 11 fatty acids (C14:0, C16:0, C16:1, C17:0, C17:1, C18:0, C18:1, C18:2, C18:3, C20:0 and C20:1. At the same time, Near Infrared (NIR spectrum of each liquid sample was obtained. Linear Discriminant Analysis (LDA was considered as pattern recognition method to develop the multivariate models. Classification errors of the LDA models generated by using NIR spectral data were 0.0% and 1.7% for the model generated by using fatty acids composition. Results confirm the possibility to discriminate Iberian pig liquid samples from animals reared under different feeding regimes on real farm conditions by using NIR spectral data or fatty acids composition. Classification error obtained using models generated from NIR spectral data were lower than those obtained in models based on fatty acids composition.Se han desarrollado modelos multivariantes, generados a partir de la composición en ácidos grasos o datos espectrales NIR, para clasificar según el régimen alimenticio cerdos Ibéricos producidos bajo condiciones no experimentales.

  5. The Swedish National Defence Research Establishment and the plans for Swedish nuclear weapons

    2001-03-01

    This study analyses the Swedish nuclear weapons research since 1945 carried out by the Swedish National Defence Research Establishment (FOA). The most important aspect of this research was dealing with protection in broad terms against nuclear weapons attacks. However, another aspect was also important from early on - to conduct research aiming at a possible production of nuclear weapons. FOA performed an extended research up to 1968, when the Swedish Government signed the Non-Proliferation Treaty (NPT), which meant the end of these production plans. Up to this date, five main investigations about the technical conditions were made, 1948, 1953, 1955, 1957 and 1965, which all together expanded the Swedish know-how to produce a bomb. The Swedish plans to procure nuclear weapons were not an issue in the debate until the mid 50's. The reason for this was simple, prior to 1954 the plans were secretly held within a small group of involved politicians, military and researchers. The change of this procedure did take place when the Swedish Supreme Commander in a public defence report in 1954 favoured a Swedish Nuclear weapons option. In 1958 FOA had reached a technical level that allowed the Parliament to make a decision. Two programs were proposed - the L-programme (the Loading Programme), to be used if the parliament would say yes to a production of nuclear weapons, and the S-programme (the Protection Programme), if the Parliament would say no. The debate on the issue had now created problems for the Social Democratic Government. The Prime Minister, Tage Erlander, who had earlier defended a procurement of nuclear weapons, was now forced to reach a compromise. The compromise was presented to the parliament in a creative manner that meant that only the S-programme would be allowed. The Government argued that the technical level did allow a 'freedom of action' up to at least the beginning of the 60's when Sweden was mature to make a decision on the issue. During this period

    The aim of this study was to determine possible relationships between farm climate conditions, recorded from day 0 to day 40 post-artificial insemination (AI), and late embryo/early fetal loss in high producing dairy cows. Pregnancy was diagnosed by rectal ultrasonography between 28 and 34 days post-AI. Fetal loss was registered when a further 80- to 86-day diagnosis proved negative. Climate variables such as air temperature and relative humidity (RH) were monitored in the cubicles area for each 30-min period. Temperature-humidity indices (THI); cumulative stressful values and episodes of acute change (defined as the mean daily value 1.2 times higher or lower than the mean daily values of the 10 previous days) of the climate variables were calculated. The data were derived from 759 cows in one herd. A total of 692 pregnancies (91.2%) carried singletons and 67 (8.8%) carried twins. No triplets were recorded. Pregnancy loss was recorded in 6.7% (51/759) of pregnancies: 5.6% (39/692) in single and 17.9% (12/67) in twin pregnancies. Using logistic regression procedures, a one-unit increase in the daily cumulative number of hours for the THI values higher than 85 during days 11-20 of gestation caused a 1.57-fold increase in the pregnancy loss, whereas the likelihood of fetal loss increased by a factor of 1.16 for each additional episode of acute variation for the maximum THI values during gestation days 0-40. THI values higher than 85 and episodes of acute variation for the maximum THI values were only recorded during the warm and cool periods, respectively. The presence of twins led to a 3.98-fold increase in pregnancy loss. In conclusion, our findings show that cumulative stressful and episodes of acute variation of climatic conditions can compromise the success of gestation during both the cool and warm periods of the year. Twin pregnancy was confirmed as a main factor associated with pregnancy loss.

  9. Social-Natural Landscape Reorganised: Swedish Forest-edge Farmers and Wolf Recovery

    Directory of Open Access Journals (Sweden)

    Sjolander-Lindqvist Annelie

    2009-01-01

    Full Text Available The politics and the underlying reasons behind the recovery of the Scandinavian wolf population are increasingly contested. According to official policy, wolves should be guaranteed a place in the Swedish natural world. However, the conflict over whether Sweden should host a wolf population sets views on biodiversity and sustainable development against the perspective that local traditions and livelihoods are threatened by the return of wolves. These diverging environmental visions can be seen as competing interests and understandings of nature and wildlife. The desire of the state and nature conservation organisations to implement measures to provide conditions fostering wolf survival are counterbalanced by local action groups and community residents struggling to maintain conditions for conserving summer pastures, opportunities for hunting with sporting dogs, and other recreational activities such as mushroom- and berry-picking. Not only are these activities considered to have high natural and cultural value, the European Union (EU has stated that small-scale farming is important for maintaining the landscape and safeguarding the survival of values associated with ′agri-environmental′ habitats. The conflict between the interest groups is essentially about the access to and use of environmental resources. Squeezed between policies safeguarding wolf populations, preventing cruelty to animals and implementing activities required by the EU agricultural programme, farmers in areas with resident wolf populations have come to take part in processes that may reinforce rural identity.

    The purpose of this study was to investigate economic conditions for farm-scale biogas production in Sweden and to calculate the nutrient and greenhouse gas benefits of such systems. To give a more general description of the agricultural sector's possibilities to produce biogas, a comparison is carried out for 3 different scales of production as follows: Alternative 1: Digestion of a small amount of liquid manure from cattle. Evolved biogas is used for heat production which is used to provide space heating and hot water for one or two cottages on the farm. Alternative 2: Digestion of a larger amount of liquid manure from pig production. The biogas is used for co-generation of heat and electricity. The heat produced is used to provide space heating and hot water on 3-4 cottages at the farm. Alternative 3: Production of approx. 6 GWh biogas/year for direct sale on the external gas market. The plant co-digests energy crops, manure and vegetable waste. In this case the following energy crops are compared: a) ensiled ley crop, ensiled maize and c) grain. In the economic analysis, most of the data used comes from German sources. Based on the current market prices for energy in Sweden, only plant alternatives where the biogas is upgraded for use as vehicle fuel are profitable for the farmer. However, one significant barrier is that there is currently no significant market for vehicle fuel-grade biogas in Sweden, makes it difficult for farmers building up new local market. The purchase price of electricity from biogas is lower in Sweden than the most countries in Europe. The current prevailing market price for electricity is on the other hand quite volatile and future price increases are likely. The debate about how to reduce GHG emissions from the agricultural has recently attracted increased interest in wider circles. It is also likely that the Swedish government will start an investment program for farm scale biogas production from year 2009. Taken together, this

    Between 1949 and 1957, 10 engineers of the Mining research and exploitation department of the CEA visited 17 Swedish mines during 5 field trips. This paper presents a compilation of the information gathered during these field trips concerning the different underground mining techniques used in Swedish iron mines: mining with backfilling (Central Sweden and Boliden mines); mining without backfilling (mines of the polar circle area). The following techniques are described successively: pillar drawing and backfilled slices (Ammeberg, Falun, Garpenberg, Boliden group), sub-level pillar drawing (Grangesberg, Bloettberget, Haeksberg), empty room and sub-level pillar drawing (Bodas, Haksberg, Stripa, Bastkarn), storage chamber pillar drawing (Bodas, Haeksberg, Bastkarn), and pillar drawing by block caving (ldkerberget).

  16. Swedish earthquakes and acceleration probabilities

    Slunga, R.

    1979-03-01

    A method to assign probabilities to ground accelerations for Swedish sites is described. As hardly any nearfield instrumental data is available we are left with the problem of interpreting macroseismic data in terms of acceleration. By theoretical wave propagation computations the relation between seismic strength of the earthquake, focal depth, distance and ground accelerations are calculated. We found that most Swedish earthquake of the area, the 1904 earthquake 100 km south of Oslo, is an exception and probably had a focal depth exceeding 25 km. For the nuclear power plant sites an annual probability of 10 -5 has been proposed as interesting. This probability gives ground accelerations in the range 5-20 % for the sites. This acceleration is for a free bedrock site. For consistency all acceleration results in this study are given for bedrock sites. When applicating our model to the 1904 earthquake and assuming the focal zone to be in the lower crust we get the epicentral acceleration of this earthquake to be 5-15 % g. The results above are based on an analyses of macrosismic data as relevant instrumental data is lacking. However, the macroseismic acceleration model deduced in this study gives epicentral ground acceleration of small Swedish earthquakes in agreement with existent distant instrumental data. (author)

    At present, suggestions as for how a JI system would be designed and implemented are being worked out on a national level in Sweden and other countries. An important question in international and national climate policy and thus in work related to JI is how to engage companies. In order to make companies interested in investing and participating in JI, the mechanisms must be compatible with the ways in which companies work. Hence, knowledge and concern of conditions for those who are supposed to implement the politics in practice would be a key issue for the institutions that shape climate policy and JI systems. Given this background and the present situation regarding JI, this report aims at providing a business perspective on the prerequisites for implementing JI in Sweden. The main question addressed in the report is: What would make Swedish companies participate in JI projects? The study underlying this report covered three workshops where representatives of in all 15 Swedish companies from different industry sectors, by working in group, determined and discussed opportunities and obstacles for participation of companies in JI as well as concrete measures as for enabling such participation. From the empirical data collected we have found that Swedish companies, if not directly opposed to JI, play a waiting game at present regarding investments and participation in specific JI projects. According to the data, companies would invest and participate in JI projects if and only if it is found to be the most competitive of different alternatives for the company to meet its carbon dioxide emission restrictions or a profitable project. The former condition applies for companies with considerable CO{sub 2} emissions, the latter for companies with low or no such emissions. However, JI is currently perceived of as risky and associated with large uncertainties. The perceived uncertainties associated with JI participation are mainly related to indistinct and ambiguous

    Livestock-associated methicillin resistant Staphylococcus aureus (LA-MRSA) is an emerging zoonotic agent that can be transmitted to people exposed to contaminated farms. This study was performed to evaluate the efficacy of a commercial farm disinfectant in reducing LA-MRSA contamination under...... applications of the disinfectant. MRSA load was measured in samples from pigs, bedding material and air and analysed statistically. While pigs remained positive with variable MRSA counts, the amount of MRSA in the air and bedding material increased significantly during the first week and then was gradually...... reduced in both groups. MRSA couldn’t be isolated from air and bedding material in the treatment group after seven applications and the load of MRSA increased immediately after discontinuation of treatment. This study suggests that this type of disinfectant is not able to eradicate LA-MRSA from animals...

  19. Evaluation of Growth and Species Composition of Weeds in Maize-Cowpea Intercropping based on Additive Series under Organic Farming Condition

    Directory of Open Access Journals (Sweden)

    2016-11-01

    Full Text Available Introduction Weeds are main factors reducing crops yield, especially under organic farming conditions (. It has been reported that weed populations are more in organic farming compared to conventional cropping systems, resulting in more reduction of growth and yield. Although the chemical control is a fast and effective way for controlling weed populations, some negative impacts of the recent weed management on public health and the natural environment, increased the concerns of using weed chemical compositions. Thus, non-chemical weed control is in high importance. Intercropping, an agronomical operation in which two or more crops are grown simultaneously in the same field, is one of the most important methods for increasing biodiversity in agricultural ecosystems (Amosse et al., 2013; Rostami et al., 2009; Yuan-Quan et al., 2012. Therefore, the current research was aimed to evaluate the possible non chemical controlling of weeds in a maize-cowpea intercropping system. Materials and methods A field experiment was conducted in the north of Khuzestan during the growing season 2013-2014. The experiment was based on a randomized complete block design with three replications. Maize and cowpea were planted in two sole crop systems and four intercropping systems based on an additive series, including T1:100 percent maize+25 percent cowpea, T2: 100 percent maize+50 percent cowpea, T3: 100 percent maize+75 percent cowpea and T4: 100 percent maize+100 percent cowpea. No chemical materials (fertilizer and pesticide were used during growing season. Environmental usage by intercropping patterns was evaluated by measuring photosynthetically active radiations (PAR (mean of five points in each plot, selected randomly and soil moisture content at three stages. At harvest time, all plants of each plot were harvested and grouped and weighed according to their species type. Complementary effect of intercropping in using environmental resources was calculated using

    2017-01-01

    Full Text Available Farmers’ production decisions and agricultural practices directly and indirectly influence the quantity and quality of natural resources, some being depleted common resources such as groundwater. Representing farming systems while accounting for their flexibility is needed to evaluate targeted, regional water management policies. Farmers’ decisions regarding investing in irrigation and adopting cropping systems are inherently dynamic and must adapt to changes in climate and agronomic, economic and social, and institutional, conditions. To represent this diversity, we developed a typology of Indian farmers from a survey of 684 farms in Berambadi, an agricultural watershed in southern India (state of Karnataka. The survey provided information on farm structure, the cropping system and farm practices, water management for irrigation, and economic performances of the farm. Descriptive statistics and multivariate analysis (Multiple Correspondence Analysis and Agglomerative Hierarchical Clustering were used to analyze relationships between observed factors and establish the farm typology. We identified three main types of farms: (1 large diversified and productivist farms; (2 small and marginal rainfed farms, and (3 small irrigated marketing farms. This typology represents the heterogeneity of farms in the Berambadi watershed.

    The first Swedish offshore wind farm Bockstigen is operating since March 1998 near the coast of Gotland. It was built as a demonstration project by the Swedish wind farm developer Vindkompaniet, the Danish wind turbine manufacturer Wind World and the British offshore construction company Seacore and partly funded under the EU-THERMIE program. Bockstigen is the fourth offshore wind farm world-wide. While at previous wind farms the main emphasis laid on the demonstration of the technical feasibility of offshore wind energy utilisation, Bockstigen was aimed at demonstrating its economic viability. A number of innovative concepts have been employed: Drilled monopile foundations were used to save costs. A new construction method has been applied making use of a jack-up barge. A new control system for the turbines and the whole wind farm was developed, which controls the maximum power output, the flicker and the reactive power consumption depending on online measurements of the actual grid state. These new developments have been implemented successfully. A substantial cost reduction compared to previous offshore projects could be achieved. (au)

    1989-01-01

    Full text: The Swedish mutation research programme in barley began about 50 years ago and has mainly been carried out at Svaloev in co-operation with the institute of Genetics at the University of Lund. The collection has been produced from different Swedish high-yielding spring barley varieties, using the following mutagens: X-rays, neutrons, several organic chemical compounds such as ethyleneimine, several sulfonate derivatives and the inorganic chemical mutagen sodium azide. Nearly 10,000 barley mutants are stored in the Nordic Gene Bank and documented in databases developed by Udda Lundquist, Svaloev AB. The collection consists of the following nine categories with 94 different types of mutants: 1. Mutants with changes in the spike and spikelets; 2. Changes in culm length and culm composition; 3. Changes in growth types; 4. Physiological mutants; 5. Changes in awns; 6. Changes in seed size and shape; 7. Changes in leaf blades; 8. Changes in anthocyanin and colour; 9. Resistance to barley powdery mildew. Barley is one of the most thoroughly investigated crops in terms of induction of mutations and mutation genetics. So far, about half of the mutants stored at the Nordic Gene Bank, have been analysed genetically; They constitute, however, only a minority of the 94 different mutant types. The genetic analyses have given valuable insights into the mutation process but also into the genetic architecture of various characters. A number of mutants of two-row barley have been registered and commercially released. One of the earliest released, Mari, an early maturing, daylength neutral, straw stiff mutant, is still grown in Iceland. The Swedish mutation material has been used in Sweden, but also in other countries, such as Denmark, Germany, and USA, for various studies providing a better understanding of the barley genome. The collection will be immensely valuable for future molecular genetical analyses of clone mutant genes. (author)

    Full Text Available Teaching about the Holocaust and other genocides is emphasized in Swedish History teaching. In Sweden there is a public authority commisioned to work with issues related to tolerance, democracy and human rights. It is this context and under these conditions, that Swedish History teachers select a variety of topics for their students to learn, as part of the History curriculum. In addition to the Holocaust, they teach about crimes against humanity committed under communist regimes, the genocide of Tutsies in Rwanda, and mass murder and ethnic cleansing in former Yugoslavia. Teachers use a multiplicity of uses of history and teaching methods. They conduct a scientific use of history when focusing on the historical contexts and explaining the background, motives and consequences of genocide. Teachers also stress the students’ personal reflections and standpoints in a moral use of history. The teaching aims at developing understanding and empathy among students.

    2008-01-01

    The purpose of this study was to investigate the psychosocial work environment for employed dairy and pig farmworkers in southern Sweden and to identify potential risk factors related to the psychosocial work environment for the development of musculoskeletal disorders (MSDs). Thirty-seven workers on 10 dairy farms and 30 workers on 10 pig farms participated in the study. The study was based on a Swedish translation of the short version of the Copenhagen Psychosocial Questionnaire (COPSOQ) for analyses of self-perceived psychosocial work environment and the general Nordic questionnaire for analyses of self-perceived MSDs. In general, the psychosocial work environment was assessed as "good" by both the dairy and pig farmworkers. However, the dairy and pig farmworkers experienced lower work demands, poorer general and mental health, and poorer vitality (physical and mental strength, vigor, and energy) compared to other occupations. Furthermore, the results indicated that the quality of leadership, feedback, and social support at work were poorer at the dairy farms than at the pig farms. No significant risk factors related to the psychosocial work environment were identified for MSDs in "the back" and in the "upper extremities." This study indicates that the psychosocial work environment for the dairy and pig farmworkers may well be improved in order to promote these workplaces as attractive and healthful. This especially seems to be the case concerning the quality of leadership, feedback, and social support at work for the dairy farmworkers. Furthermore, the present study suggests the probability that physical factors are more likely to lead to MSDs among employed livestock workers than factors related to the psychosocial work environment.

  10. Occurrence and Spread of Quinolone-Resistant Escherichia coli on Dairy Farms

    2016-01-01

    ABSTRACT Quinolone-resistant Escherichia coli (QREC) is common in feces from young calves, but the prevalence and genetic diversity of QREC in groups of cattle of other ages and the farm environment are unknown. The aims of the study were to obtain knowledge about the occurrence of QREC on dairy farms, the genetic diversity of QREC within and between farms, and how these relate to the number of purchased animals and geographic distances between farms. We analyzed the within-sample prevalence of QREC in individual fecal samples from preweaned dairy calves and postpartum cows and in environmental samples from 23 Swedish dairy farms. The genetic diversity of the QREC isolates on 10 of these farms was assessed. In general, QREC was more prevalent in the dairy farm environment and in postpartum cows if QREC was commonly found in calves than if QREC was rare in calves. In particular, we found more QREC organisms in feed and water troughs and in environments that may come into contact with young calves. Thus, the results suggest that QREC circulates between cattle and the farm environment and that calves are important for the maintenance of QREC. Some genotypes of QREC were widespread both within and between farms, indicating that QREC has spread within the farms and likely also between farms, possibly through purchased animals. Farms that had purchased many animals over the years had greater within-farm diversity than farms with more closed animal populations. Finally, animals on more closely located farms were more likely to share the same genotype than animals on farms located far apart. IMPORTANCE This study investigates the occurrence of a specific type of antimicrobial-resistant bacterium on dairy farms. It contributes to increased knowledge about the occurrence and spread of these bacteria, and the results pave the way for actions or further studies that could help mitigate the spread of these bacteria on dairy farms and in the community as a whole.

  15. Heterogeneous Boundary Layers through the Diurnal Cycle: Evaluation of the WRF Wind Farm Parameterization using Scanning Lidar Observations and Wind Turbine Power Measurements during a Range of Stability Conditions

    Science.gov (United States)

    Lundquist, J. K.

    2015-12-01

    As wind energy deployment increases, questions arise regarding impacts on local climates and how these impacts evolve with the diurnal cycle of the boundary layer. Satellite observations suggest nocturnal increases of surface temperatures, and measurements of turbine wakes document stronger and more persistent reductions of wind speed and increases in turbulence downwind of turbines during stable conditions. Validations of mesoscale parameterizations of these effects have been constrained to idealized conditions defined by neutrally-stratified conditions and/or limited wind directions and wind speeds, or by comparison to idealized large-eddy simulations. Synthesis of conventional meteorological measurements and unconventional measurements can offer unique insights for validating models over a large heterogeneous domain. The CWEX-13 field experiment provides an extensive dataset for such validation at spatial scales on the order of 10 km in a range of atmospheric stability and wind conditions. CWEX-13 took place within a 300 MW wind farm in central Iowa during summer 2013 and featured strong diurnal cycles. The wind turbines are sited irregularly, creating a heterogenous "canopy". Three profiling lidars, numerous surface flux stations, and a scanning lidar sampled wakes from multiple turbines. Further, the wind farm owner/operator has provided access to turbine power production and wind speed measurement data for model validation, providing ~ 200 measurements of proxies that integrate the wind profile over the rotor disk, from 40 m to 120 m above the surface. Building on previous work that identified optimal physics options, grid configurations, and boundary condition data sets by comparison to lidar wind profile measurements, we execute simulations with the WRF Wind Farm Parameterization for a ten-day period featuring moderate winds and strong diurnal cycles. We evaluate simulations with different modeling choices (e.g., vertical resolution, approaches to

    2009-05-01

    The aim of this study was to elucidate the predominant discourse in the field of Swedish nursing in 2000, 25 years after nursing was introduced as an academic discipline in Sweden. The method used was content analysis and deconstructive analysis of discourses. Laws, statutes, regulations, and examination requirements, including official reports, recruitment campaigns, and media coverage, were analyzed. The findings uncovered competing discourses striving to gain hegemony. In the public sector, official requirements competed against the media fixation on gender stereotypes and the realities of local recruitment campaigns. Media has a major role in disseminating prevailing conceptions and conventions pertaining to the nursing profession. As a result, decision makers, students, patients, and family members could get lower expectations of the professional competence of nursing practitioners than would otherwise have been the case in the absence of media exposure.

  17. Studies in Swedish Energy Opinion

    Energy Technology Data Exchange (ETDEWEB)

    Holmberg, Soeren; Hedberg, Per

    2012-07-01

    the 1970s, energy production was politicized big time in the industrialized world. The birth of the environmental movement, the oil crises in 1973 - 74 and the beginning conflict surrounding civilian nuclear power, put energy issues center stage on the political agenda. Energy policies - especially related to the development of nuclear power - came to dominate election campaigns, like in Sweden in 1976 or be the subject of referendums, like in Austria in 1978 or in Sweden in 1980. Critical voices toward the peaceful use of nuclear power - having started in America before being exported to Europe - gained real strength and public support all over the Western world by the nuclear accident at the Three Mile Island plant in Harrisburg, Pennsylvania in 1979. The energy genie was out of the bottle and out to stay. Fueled by the nuclear meltdowns in Chernobyl in 1986 and in Fukushima in 2011 and supplemented by conflicts over how to reduce the use of oil and coal, how to sensibly exploit the waste gas reserves, and how to develop renewable energy sources based on sun, wind and waves – have made all kinds of energy issues the focal point of political contentions ever since the early 1970s. In Sweden, as in many other countries, energy policies - often with nuclear power in the center - have been one of the most fought-over policy areas during the last thirty-forty years. And the contentious character of energy policies is not limited to the elite level of politics - to politicians, to media pundits or to lobbyists. It is also manifest among ordinary citizens. Energy issues - nuclear power and wind power in particular - are highly polarizing among voters as well. Given this historic background, starting in the 1970s, it was rather natural that energy questions - featuring most prominently questions related to nuclear power - would be important parts of the voter surveys performed by the Swedish National Elections Studies (SNES) at the Univ. of Gothenburg.

    2012-04-01

    Full Text Available The view on enterococci has over the years shifted from harmless commensals to opportunistic but important pathogens mainly causing nosocomial infections. One important part of this development is the emergence of vancomycin resistance enterococci (VRE. The term VRE includes several combinations of bacterial species and resistance genes of which the most clinically important is Enterococcus faecium with vanA type vancomycin resistance. This variant is also the most common VRE among farm animals. The reason for VRE being present among farm animals is selection by extensive use of the vancomycin analog avoparcin for growth promotion. Once the use of avoparcin was discontinued, the prevalence of VRE among farm animals decreased. However, VRE are still present among farm animals and by spread via food products they could potentially have a negative impact on public health. This review is based on the PhD thesis Vancomycin Resistant Enterococci in Swedish Broilers – Emergence, Epidemiology and Elimination and makes a short summary of VRE in humans and food producing animals. The specific situation regarding VRE in Swedish broiler production is also mentioned.

    Abstract. This paper gives an answer to important questions such as: “what is sustainability of farms?” and “how to assess sustainability of farms?”. First, evolution of the “concept” and the major approaches for assessing sustainability of farms is discussed. More adequate definition of the farm sustainability is suggested as ability of a particular farm to maintain its governance, economic, social and ecological functions in a long term. Next, a specific for the conditions of Bulgarian farm...

    Increased suicide rates for military personnel suffering from post-traumatic stress disorders have been reported in various countries. Although it is known that some peacekeepers are exposed to potentially traumatic events and are thus at risk of suffering from post-traumatic stress reactions, only a few studies have examined suicide rates in this group. Therefore, the aim of this study was to investigate the suicide rate among former Swedish peacekeeping personnel. We compared 39,768 former Swedish peacekeepers to the general population in the National General Population Registry and the Cause-of-Death Registry. A lower number of suicides was found among former Swedish peacekeepers than in the general population. In conclusion, Swedish personnel serving in international peace-keeping operations do not show a higher suicide rate than the general population. Unique problems associated with this research area are discussed.

    Nitrogen (N) application significantly increases maize yield; however, the unreasonable use of N fertilizer is common in China. The analysis of crop yield gaps can reveal the limiting factors for yield improvement, but there is a lack of practical strategies for narrowing yield gaps of household farms. The objectives of this study were to assess the yield gap of summer maize using an integrative method and to develop strategies for narrowing the maize yield gap through precise N fertilization. The results indicated that there was a significant difference in maize yield among fields, with a low level of variation. Additionally, significant differences in N application rate were observed among fields, with high variability. Based on long-term simulation results, the optimal N application rate was 193 kg ha -1 , with a corresponding maximum attainable yield (AY max ) of 10 318 kg ha -1 . A considerable difference between farmers' yields and AY max was observed. Low agronomic efficiency of applied N fertilizer (AE N ) in farmers' fields was exhibited. The integrative method lays a foundation for exploring the specific factors constraining crop yield gaps at the field scale and for developing strategies for rapid site-specific N management. Optimization strategies to narrow the maize yield gap include increasing N application rates and adjusting the N application schedule. © 2016 Society of Chemical Industry. © 2016 Society of Chemical Industry.

    policy on its programme got the Prime Minister chair. Four years later, 1980, the Swedish parliament decided, after a national referendum, that nuclear power under certain conditions would be phased out by the year 2010. The decision in parliament means that the phase-out of nuclear power shall start within half a year and the reasons given are purely political. One 600 MW unit at the Barsebaeck nuclear power plant shall be closed by 1 s July 1998 a few months before the next general election, and the second twin unit at Barsebaeck three years later. A precondition for the closing down the second unit is that the resulting loss of electricity production can be compensated by new power sources and more efficient use of electricity. There are no dates fixed for the closure of the remaining ten Swedish reactors. Thus the old decision from 1980 to phase-out the whole nuclear programme by 2010 has now been abandoned. The closing of nuclear power plants would mean higher electricity prices. This would be a threat to the Swedish electricity intensive industry (paper and steel mills), because of the sharp international competition. The Swedish industry and the trade unions (closely connected to the social-democratic party) have therefore for a long time been opposing the new energy policy. The result is that the public is well aware of the need for the continued use of nuclear power and a great majority would prefer the continued use of a the twelve nuclear reactors

  7. Use and non-use values as motivational construct dimensions for farm animal welfare: impacts on the economic outcome for the farm.

    Hansson, H; Lagerkvist, C J; Azar, G

    2018-01-24

    This study explored how farmers' motivation in terms of use values and/or non-use values to work with farm animal welfare are associated with the economic outcome for the farm. Use values in farm animal welfare refer to economic value derived from productivity and profitability considerations. Non-use values in farm animal welfare refer to economic value derived from good animal welfare, irrespective of the use the farmer derives from the animal, currently or in the future. The analysis was based on detailed information about the income statements of a sample of Swedish dairy farmers, obtained from the Swedish Farm Economic Survey, complemented with survey information about their perceived use and non-use values in farm animal welfare. The findings suggest that farm economic outcome is significantly associated with motivation in terms of use values, but not so much with motivation in terms of non-use values. This is interesting from a policy point of view, because it indicates that farmers with different approaches to farm animal welfare may experience different economic outcomes for their farms. Findings can, for instance, be used to strengthen farmers' engagement in various private quality assurance standards, which generally focus on values of non-use type, by pointing to that realisation of such values will not impair the economic outcome of the farms. Moreover, findings also suggest that farmers' economic incentives for engagement in such standards may need to be further strengthened in order to become more attractive, as findings point to that a focus on non-use values generally is not associated with more favourable economic outcomes.

  13. Estimating Swedish biomass energy supply

    International Nuclear Information System (INIS)

    Johansson, J.; Lundqvist, U.

    1999-01-01

    Biomass is suggested to supply an increasing amount of energy in Sweden. There have been several studies estimating the potential supply of biomass energy, including that of the Swedish Energy Commission in 1995. The Energy Commission based its estimates of biomass supply on five other analyses which presented a wide variation in estimated future supply, in large part due to differing assumptions regarding important factors. In this paper, these studies are assessed, and the estimated potential biomass energy supplies are discusses regarding prices, technical progress and energy policy. The supply of logging residues depends on the demand for wood products and is limited by ecological, technological, and economic restrictions. The supply of stemwood from early thinning for energy and of straw from cereal and oil seed production is mainly dependent upon economic considerations. One major factor for the supply of willow and reed canary grass is the size of arable land projected to be not needed for food and fodder production. Future supply of biomass energy depends on energy prices and technical progress, both of which are driven by energy policy priorities. Biomass energy has to compete with other energy sources as well as with alternative uses of biomass such as forest products and food production. Technical progress may decrease the costs of biomass energy and thus increase the competitiveness. Economic instruments, including carbon taxes and subsidies, and allocation of research and development resources, are driven by energy policy goals and can change the competitiveness of biomass energy

  16. Safety Assessment - Swedish Nuclear Power Plants

    International Nuclear Information System (INIS)

    Kjellstroem, B.

    1996-01-01

    After the reactor accident at Three Mile Island, the Swedish nuclear power plants were equipped with filtered venting of the containment. Several types of accidents can be identified where the filtered venting has no effect on the radioactive release. The probability for such accidents is hopefully very small. It is not possible however to estimate the probability accurately. Experiences gained in the last years, which have been documented in official reports from the Nuclear Power Inspectorate indicate that the probability for core melt accidents in Swedish reactors can be significantly larger than estimated earlier. A probability up to one in a thousand operating years can not be excluded. There are so far no indications that aging of the plants has contributed to an increased accident risk. Maintaining the safety level with aging nuclear power plants can however be expected to be increasingly difficult. It is concluded that the 12 Swedish plants remain a major threat for severe radioactive pollution of the Swedish environment despite measures taken since 1980 to improve their safety. Closing of the nuclear power plants is the only possibility to eliminate this threat. It is recommended that until this is done, quantitative safety goals, same for all Swedish plants, shall be defined and strictly enforced. It is also recommended that utilities distributing misleading information about nuclear power risks shall have their operating license withdrawn. 37 refs

    Full Text Available Poverty alleviation and environmental preservation are very important issues to many governments. Alley farming is beneficial to the environment because it conserves soil and sustains yields over time. Specifically, alley farming reduces soil erosion, which is a major problem in Thailand. Alley farming was conducted on a farmer’s field at Khaokwan Thong, a village in Uthaithani Province, Northern Thailand. We did a two-by-two factorial with and without alley farming, and with and without fertilizer. From this study, we observed that the two species used, Leucaena leucocephala and Acacia auriculiformis, grow well in Thailand, and that alley farming is suitable for Thailand. Few Thai farmers have heard about alley farming. However, it is nevertheless useful to know that there is potential for alley farming in Thailand using the two species. These plants, based upon the diameter and height measurements provided, grew well.

  1. Air quality in Swedish cities; Luftkvalitet i taetorter

    Air quality in Swedish cities has improved considerably over the last decades as a result of reduced emissions from traffic, industrial activity and households. The situation is however far from acceptable, and no further improvement is seen during recent years. Urban air pollution is considered to contribute to the death of more than a thousand people in Sweden each year. Measurements of air quality in Swedish cities are carried out since many years. The measurements have shown that concentrations of all serious air pollutants but ozone have decreased strongly since the 1980s. The improvement is attributed to reduced emissions from motor traffic by means of catalytic converters and cleaner fuels as well as decreased emissions from industrial activity and energy production in Sweden and neighbouring countries. The present report does however show no further downward trend for concentrations of air pollutants in Swedish cities since the late 1990s, and the concentrations of the winter 2002/2003 were higher than several previous winters. This information is gained from measurements done by around forty municipalities and gathered within the so called URBAN-measurement-net managed by the IVL Swedish Environmental Research Institute, and additional information from around ten municipalities which perform own measurements. Climatic variability may play an important role for the increase seen in the winter of 2002/2003, but it is also probable that continuously increasing traffic have counteracted some of the ameliorative environmental effects of improved exhaust emission control and cleaner petrol and diesel fuels. Measurements of the winter 2002/2003 show that air quality conditions are unacceptable in perhaps half of the Swedish cities, and that they run the risk of not being able to attain environmental quality standards for one or more substances. The standards for particulate matter and nitrogen dioxide are those most difficult to manage within the time limits set

    Within the next few decades, wind farms with an extension of many square kilometres probably will be built in Swedish coastal waters. These installations may affect the ecological communities in various ways, e.g.; by the already known reef-effect, by changing the population structure of key predators such as fish and birds and thereby cause trophic cascades down into the benthic community or by causing changes in the hydrology that may benefit some species, mainly soft bottom species, while others may be disadvantaged. How the wind farms will affect the ecological communities depends probably very much on the initial conditions. During the period 2005-2009 a study was carried out with the aim to investigate the benthic community structure on hard bottoms, before and after larger wind farms have been constructed. The areas explored were Skottarevet in Kattegat, Lillgrund in Oeresund, Utgrunden II in southern Kalmar Strait, Kaarehamn off north-eastern Oeland and Klasaadern off south-western Gotland. For legal and economic reasons, only one farm, Lillgrund was constructed during the project period. Significant differences were found at both species and functional level. The largest divergence was found between the Kattegat and the Baltic Sea with large differences in species composition and in part also with other functional groups. Furthermore, between the Baltic Sea sites, significant differences were also found. The natural communities in the two straits had significantly higher biomass of blue mussels (M. edulis) per square meter compared with the open areas at Gotland and Oeland. In addition,the algal flora differed significantly. Filamentous brown algae favoured by eutrophication dominated the substrate in the straits while the bottoms along the open coastlines were covered with perennial red algae. The wind farm at Lillgrund affected the benthic communities moderately but significant. Mussels and barnacles colonized the surface of the towers and the granite

    In a first part, this report presents some characteristics and key aspects of the anaerobic digestion process. It highlights its environmental benefits, notices that energy production from breeding effluents is not optimal, that this energy is easily exportable, but that this process does not process nitrogen and phosphorus surpluses. It gives an overview of the status of practices in France, in Germany where incentive policies have promoted the development of on-farm anaerobic digestion for many years, in Denmark, in Sweden and in Switzerland where the gas feeds directly the network. It presents the legal and regulatory framework for installations classified with respect to the protection of the environment, for the digestate approval and standardization, for the connection to the electric network, for bio-gas transportation and injection in networks, and for taxes. It proposes an economic analysis: investments and scale effects, cogeneration and electricity sale, perspectives for biogas direct sale, waste and digestate value, and so on. It proposes a review of research and development works in this domain, and finally addresses some issues of economic and regional development

    2009-02-15

    The purpose of this report is to describe the environmental monitoring measures performed for the Lillgrund Offshore Wind Farm and to summarize the results and conclusions. Construction work started in 2006 and the plant was energized in December 2007. At the time of construction Lillgrund was the third largest wind farm offshore in the world and the first large offshore wind farm in Sweden. The purpose of the environmental monitoring is to ensure that there are no negative impacts on the environment stemming from construction of the Lillgrund wind farm as well as to ensure that the conditions stated by the authorities and the Company's commitments are met. The aim is also to collect more information and knowledge on the possible environmental impact for future offshore wind farm projects. For the Lillgrund project, all monitoring programs were included in one document, Monitoring Program - Lillgrund. It was included as part of the procedures to ensure that the Swedish legal requirements on operators control were followed. The authorities approved the document before construction started. The monitoring measures performed during the construction phase included: - A feedback and monitoring program on dredging and spillage; - A feedback and monitoring program on flora and fauna; - Studies and inspections of the refilling and re-establishment of the sea bottom; - Procedure for operators control. The mean measured sediment spillage, as part of the monitoring program on dredging and spillage, varied between 4.6 - 4.8% depending on dredger used. The maximum value allowed by the conditions is 5%. In general, the calculated values for suspended material were limited and the critical value of 0.01 kg/m3 was exceeded only in minor areas for a very limited time. No corrective actions were required. The deposition of sediment was very low and even at the most effected sites it was only just over 1 mm. The largest dredging volumes were for the foundation work, in total 82

    Objectives Children and young people growing up in a farm environment run a greater risk of being injured or dying in an accident than their non-farming counterparts. This study examines farming parents’ attitudes and experiences of having their children grow up on farms, one of the most dangerous work environments as their home, everyday environment and playground. Method Data were collected using two ethnological methods, a question list and interviews, with a study population of 20 parents. The data were analysed phenomenologically. Results The analysis pursued four themes: i) the most dangerous places and situations on the farm; ii) children’s tasks on the farm; iii) children as a safety risk on the farm; and iv) farm risk education for children. Conclusions Most parents know the risks on their farm, but are sometimes careless when working under stress or exhaustion. Some parents wanted more information and some wanted compulsory preventative or safety measures by manufacturers, e.g. a safety belt as standard on the extra seat in tractors. Children’s friends were described as one of the greatest risks for injury due to peer pressure. Some parents mentioned that people who grow up on farms are sometimes ‘blind’ to the dangers. Other parents seemed to overlook the risks and had their children carrying out tasks for which they were not mentally or physically equipped. Some of the tasks the children reportedly carried out on farms contravened Swedish legislation. It is thus important for farming parents to be repeatedly reminded of the risks to their children and to increase their awareness of how to prevent and eliminate risks in order to avoid accidents on the farm. The situation for farm children is highlighted in a critical discussion. PMID:27362751

BCS assessed visually with 2-week intervals was also smoothed. EBbody was calculated from BW changes only, and in conjunction with BCS...... to be developed for breeds and parities. These standard body protein change functions allow EBbody to be estimated from frequent BW measurements alone, that is, in the absence of BCS measurements.

  13. Medium fidelity modelling of loads in wind farms under non-neutral ABL stability conditions – a full-scale validation study

    DEFF Research Database (Denmark)

    Larsen, Gunner Chr.; Larsen, Torben J.; Chougule, A.

    2017-01-01

    The aim of the present paper is to demonstrate the capability of medium fidelity modelling of wind turbine component fatigue loading, when the wind turbines are subjected to wake affected non-stationary flow fields under non-neutral atmospheric stability conditions. To accomplish this we combine...... the classical Dynamic Wake Meandering model with a fundamental conjecture stating: Atmospheric boundary layer stability affects primary wake meandering dynamics driven by large turbulent scales, whereas wake expansion in the meandering frame of reference is hardly affected. Inclusion of stability (i.e. buoyancy......) in description of both large- and small scale atmospheric boundary layer turbulence is facilitated by a generalization of the classical Mann spectral tensor, which consistently includes buoyancy effects. With non-stationary wind turbine inflow fields modelled as described above, fatigue loads are obtained using...

  14. IRT analyses of the Swedish Dark Triad Dirty Dozen

    Directory of Open Access Journals (Sweden)

    Danilo Garcia

    2018-03-01

    Full Text Available Background: The Dark Triad (i.e., Machiavellianism, narcissism, and psychopathy can be captured quickly with 12 items using the Dark Triad Dirty Dozen (Jonason and Webster, 2010. Previous Item Response Theory (IRT analyses of the original English Dark Triad Dirty Dozen have shown that all three subscales adequately tap into the dark domains of personality. The aim of the present study was to analyze the Swedish version of the Dark Triad Dirty Dozen using IRT. Method: 570 individuals (nmales = 326, nfemales = 242, and 2 unreported, including university students and white-collar workers with an age range between 19 and 65 years, responded to the Swedish version of the Dark Triad Dirty Dozen (Garcia et al., 2017a,b. Results: Contrary to previous research, we found that the narcissism scale provided most information, followed by psychopathy, and finally Machiavellianism. Moreover, the psychopathy scale required a higher level of the latent trait for endorsement of its items than the narcissism and Machiavellianism scales. Overall, all items provided reasonable amounts of information and are thus effective for discriminating between individuals. The mean item discriminations (alphas were 1.92 for Machiavellianism, 2.31 for narcissism, and 1.99 for psychopathy. Conclusion: This is the first study to provide IRT analyses of the Swedish version of the Dark Triad Dirty Dozen. Our findings add to a growing literature on the Dark Triad Dirty Dozen scale in different cultures and highlight psychometric characteristics, which can be used for comparative studies. Items tapping into psychopathy showed higher thresholds for endorsement than the other two scales. Importantly, the narcissism scale seems to provide more information about a lack of narcissism, perhaps mirroring cultural conditions. Keywords: Psychology, Psychiatry, Clinical psychology

  15. Household Metabolism in the Five Cities. Swedish National Report - Stockholm

    International Nuclear Information System (INIS)

    Carlsson-Kanyama, Annika; Karlsson, Rebecka

    2002-08-01

    The study present results from a European project, ToolSust, in which direct and indirect energy use of household consumption is quantified. The focus is on households in Stockholm and how their spending contributes to energy use. A Dutch energy analyses programme, EAP, was modified to portray Swedish conditions, and analyses of more than 300 consumer goods were performed. These data were matched with information about family expenditure patterns from 1996. Six households were analysed, Swedish average, Stockholm City average and four households from Stockholm City. The results show that it is possible to portray households' total energy use, even the indirect one, with the help of the EAP programme and Swedish statistics. Further, indirect energy use may account for more than half of households total energy use and therefore it needs to be considered in policy making. The total primary energy use for the average households varied from 240 to 260 GJ during 1996. Heating, food and transportation were large contributors. The energy efficiency of total household spending varied from 8.8 MJ per Euro 13 MJ per Euro. Information about the energy efficiency on spending is valuable but cannot be presented and used without considering basic needs and quality of life. The total energy use per person varied from 50 to 350 GJ per year, a difference of factor seven. The analyses of energy efficiency of spending, MJ per SEK, indicate important opportunities for less energy demanding spending patterns, but those with low incomes have fewer opportunities than those with high incomes. The energy profiles for different households show that the individual ones may differ a lot from the average picture. There is a need for individual household advice about how to find more energy efficient spending patterns. Large cuts in household energy use means substantial changes in both energy intensity of goods and services and expenditure profiles. Expenditure levels should also be questioned

  16. Swedish students' interpretations of food symbols and their perceptions of healthy eating. An exploratory study.

    Neuman, Nicklas; Persson Osowski, Christine; Mattsson Sydner, Ylva; Fjellström, Christina

    2014-11-01

    This study used focus group discussions to investigate how a group of Swedish University students (24 women and five men) interpret symbols with claims about health and/or symbols with information about nutrition. The participants mostly talked about farming methods and food processes when asked about health and nutrition symbols. The Swedish Keyhole was the most familiar symbol to the participants but they had scant knowledge of its meaning. Symbols that were judged to be the most useful in guiding food choices were, according to the participants, symbols showing information about number of calories and/or nutrients. However, the most striking finding is still that the food experts' medical discourse, i.e. the focus on physical health and nutritional effects on the individual body, seems to be inconsistent with the participants' perceptions of healthy eating and risk. The participants rather used what we call an "inauthenticity discourse" where health and risks are judged in relation to farming methods, industrial food production, additives and other aspects of the food that are unknown to the individual. Despite limitations considering the number of participations and their relative homogeneity, these findings contribute to a further understanding of the gap between experts and the public when it comes to perceptions of healthy eating and risks. If this is a broader phenomenon, then we argue that this must be acknowledged if information about health and risk is to be communicated successfully. Copyright © 2014 Elsevier Ltd.

    Selection lines of sheep with low and high CH yield (g/kg DMI; CH/DMI) are being developed on the basis of feeding pelleted alfalfa hay at 2.0 times maintenance ME requirements in respiration chambers, but their divergence under predominant grazing conditions, as in New Zealand, is not known. The objectives of this study were to determine CH emissions and rumen fermentation characteristics in sheep from low and high CH/DMI selection lines while grazing pasture. Two grazing experiments were conducted with 42 selection line ewes in March 2013 (Exp. 1) and 98 selection line progeny ewe hoggets in October/November 2014 (Exp. 2), with CH emissions estimated by the SF tracer technique and DMI estimated by titanium oxide in combination with natural long-chain -alkanes. Total daily CH production (g/d) was similar between high and low CH/DMI selection line sheep in Exp. 1 and lower for low CH/DMI progeny compared with high CH/DMI progeny in Exp. 2 ( sheep compared with high CH/DMI selection line sheep in Exp. 1 ( sheep compared with high CH/DMI selection line sheep in both experiments. The current study indicates that differences in CH/DMI and VFA concentrations in selection line sheep, previously established on alfalfa pellets, are also present to a similar magnitude when grazing pasture.

  3. Science communication and the Swedish acrylamide "alarm".

    Science.gov (United States)

    Lofstedt, Ragnar E

    2003-01-01

    On April 24, 2002 the Swedish National Food Administration along with a group of researchers at the University of Stockholm raised an alarm regarding potential health risks associated with eating fried and baked foods such as potatoes and bread. Scientists had found high levels of acrylamide (up to 500 times more acrylamide than that allowed in drinking water by the World Health Organisation), a substance widely believed to cause cancer, in cooked high starch foods. The outcomes of this "alarm" were immediate. In Sweden sales of chips fell by 30-50 percent over a 3-day period following the press conference, and share prices among several fried food manufacturers fell substantially, as stock analysts were fearful that consumption of fried foods would decrease significantly. Four days after the press conference, however, consumers began eating fried food as normal and a number of researchers and journalists in Sweden and elsewhere took the view that the alarm had been both exaggerated and ill placed. In this study, I evaluate the science communication process associated with the scare, based on a content analysis of a select group of Swedish broad sheets from just previous to the April 2002 press conference to the present time (December 2002). In addition, the study is based on interviews with the various Swedish regulators involved in the process itself (in particular at the Swedish National Food Administration) as well as with the scientists responsible for the study at Stockholm University and relevant journalists and politicians.

  7. SWEDISH CRIME FICTION AS SOCIALLY INVOLVED LITERATURE

    Directory of Open Access Journals (Sweden)

    Monika Samsel-Chojnacka

    2011-01-01

    Full Text Available Swedish crime novel has been transforming for many years to become more socially involved. The ambition of many writers is not only to entertain the readers but also to participating in the social debate, criticizing the political and economical system, focusing on important issues such as violence against women, exploitation of working class by the privileged ruling class, the problems of a modern family and the situation of immigrants. Since the moment when in the mid 60’s two journalists Maj Sjöwall and Per Wahlöö decided to use popular literature to spread social matters many other Swedish writers have decided to follow their way. Some of them are journalists – like Liza Marklund, Börge Hellström and Anders Roslund or Stieg Larsson. Their novels as well as the ones written by Henning Mannkel on Kurt Wallander have become crucial evidence of changes of Swedish society in the past twenty years. Modern Swedish crime fiction illustrates the population in the model fashion that is the reason why it can become one of the interests of the sociology of literature.

  11. Prevalence of footrot in Swedish slaughter lambs

    Directory of Open Access Journals (Sweden)

    Nyman Ann-Kristin J

    2011-04-01

    Full Text Available Abstract Background Footrot is a world-wide contagious disease in sheep and goats. It is an infection of the epidermis of the interdigital skin, and the germinal layers of the horn tissue of the feet. The first case of footrot in Swedish sheep was diagnosed in 2004. Due to difficulties in distinguishing benign footrot from early cases of virulent footrot and because there is no possibility for virulence testing of strains of Dichelobacter nodosus in Sweden, the diagnosis is based of the presence or absence of clinical signs of footrot in sheep flocks. Ever since the first diagnosed case the Swedish Animal Health Service has worked intensively to stop the spread of infection and control the disease at flock level. However, to continue this work effectively it is important to have knowledge about the distribution of the disease both nationally and regionally. Therefore, the aims of this study were to estimate the prevalence of footrot in Swedish lambs at abattoirs and to assess the geographical distribution of the disease. Methods A prevalence study on footrot in Swedish lambs was performed by visual examination of 2000 feet from 500 lambs submitted from six slaughter houses. Each foot was scored according to a 0 to 5 scoring system, where feet with score ≥2 were defined as having footrot. Moreover, samples from feet with footrot were examined for Dichelobacter nodosus by culture and PCR. Results The prevalence of footrot at the individual sheep level was 5.8%, and Dichelobacter nodosus was found by culture and PCR in 83% and 97% of the samples from feet with footrot, respectively. Some minor differences in geographical distribution of footrot were found in this study. Conclusions In a national context, the findings indicate that footrot is fairly common in Swedish slaughter lambs, and should be regarded seriously.

    Full Text Available Linseed varieties were studied in variety trials and under farm conditions in south-western Finland in the years 2007−2010. The variation in yield, oil, protein, SDG lignan, cadmium and lead contents were studied in 8 oil and 2 fibre linseed varieties. Genotypic, environmental and genotype x environment interaction variance estimates were calculated. Fibre varieties ‘Belinka’ and ‘Martta’ had higher protein and lower oil contents than oil linseed varieties.The SDG lignan contents of linseed varieties varied between 3635−9560 mg kg-1. Rather high genotypic variance was found in yield, oil, protein and SDG lignan contents. Variety ‘Laser’ had lower SDG lignan content. ‘Abacus’, ‘Helmi’ and ‘Martta’ had the highest SDG lignan contents. Variation in cadmium and lead contents were caused by environmental effects. The highest cadmium contents, 0.82−1.69 mg kg-1, were found in soils fertilized by wastewater sludge about 20 years ago and at fields with low bottom soil pH (4.1−4.5.

    1987-01-01

    The Swedish assessment of RELAP5/MOD2 is a part of the International Code Assessment program which is organized by the US NRC. The major part of the experimental data used for assessment is of Swedish origin. The data encompass critical flow and level swell data from the Marviken facility. A part of the agreed assessment matrix has been completed. Comparison with BWR integral test data shows that the major phenomena which control the core cooling during intermediate and large break LOCA are qualitatively reproduced by RELAP5. Assessment against separate and integral experiments shows that the dominant uncertainty in prediction of clad temperatures is due to a poor calculation of dryout. Predicted post dryout wall temperatures, given the experimental dryout location as input parameter, generally agree well with data. Simulations of level swell following depressurization of the large diameter Marviken vessel showed that RELAP5/MOD2 was able to calculate overall axial void profiles in fair agreement with data. The assessment indicated that increasing the modeling detail could give rise to numerical instabilities. Assessment against large scale critical flow data revealed that the agreement with data was somewhat dependent on upstream fluid conditions and modeling. Low quality two phase flow was, in general, accurately predicted while subcooled liquid flow and saturated steam flow were generally overpredicted if no discharge coefficient was applied

    The objectives of this study are to describe dairy farm demographic and socioeconomic conditions in the top 100 counties in the United States for dairy sales in 2007, and to describe the association of dairy farm demographics with socioeconomic conditions. The top 100 counties were responsible for 56% of all US dairy sales in 2007 with a median growth rate of 78% compared with 1997. Counties varied widely for farm demographics with as few as 5 very large dairy farms that averaged $17,924,000 in dairy sales per farm to as many as 1,730 dairy farms with less than $250,000 in dairy sales per farm. Most of the top 100 dairy counties had higher illiteracy rates, a higher proportion of residents without a high school degree, and lower median incomes than state averages, but unemployment rates were similar to the state average. The socioeconomic measures were from public records and not collected specifically for this research. Nevertheless, the top dairy counties in the western states tended to have poorer socioeconomic conditions than the top dairy counties in other regions, and significant associations were observed between dairy farm demographics and socioeconomic conditions. Having many dairy farms was associated more favorably with county socioeconomic conditions than having high dairy sales. Copyright © 2011 American Dairy Science Association.

    Biosecurity routines at herd level may reduce the probability of introduction of disease into the herd, but some measures may be regarded as expensive and cumbersome for the farmers. Custom-made measures based on individual farm characteristics may aid in improving the actual application of on-farm biosecurity. The aim of the study was to provide a tool for calculating the effects of different biosecurity measures and strategies on the individual farm level. A simple model was developed to assess the risk of disease introduction and the need for biosecurity measures in individual farms. To illustrate the general applicability of the tool, it was applied to theoretical examples of Swedish cattle and pig farms and diseases endemic in those animal species in the EU, in two scenarios with different between-farm contact patterns. The model illustrated that the most important factors affecting the risk, and the effect of biosecurity measures such as quarantine routines and protective clothing, were the frequency of between-farm contacts and prevalence of the disease. The risk of introduction as well as the effect of biosecurity measures differed between farm types and disease transmission routes. Adapting contact patterns to mitigate a specific disease risk was as important as biosecurity measures for some farm types, but the largest effect was seen when combining biosecurity measures with more planned contact patterns. The risk assessment model proved useful for illustrating the risk of introduction of endemic diseases and the mitigating effect of different biosecurity measures on farm level. Model outputs could be used to justify prioritisation of measures or adapting contact patterns. The theoretic exercise of adjusting model inputs and comparing outputs may help veterinary advisors to understand farm-specific risks and motivate farmers to improve biosecurity in their individual farm, as it can be tailored to each farmer's needs and preferences.

    To psychometrically evaluate the Satisfaction with Life Scale in two cohorts of first-episode psychosis patients in the Danish National Schizophrenia Project and in the Swedish Parachute Project. Four properties of the Satisfaction with Life Scale were examined in the Danish cohort (explorative investigation) and then confirmed in the Swedish cohort: (1) the factor structure; (2) correlations between subscales; (3) internal consistencies of subscales; and (4) main tendencies (arithmetic means) and variations (standard deviations) of subscales. The relations between the Satisfaction with Life Scale and various life conditions were investigated in the Swedish cohort. For both samples, the analysis indicated that the obtained four-dimensional 11-item scale had satisfactory properties. Moderately high scores were obtained in the four subscales: "living," "social relationships," "self and present life" and "work." They correlated positively with each other, the internal consistencies of the subscales were acceptable and the means for the subscales indicated no apparent floor or ceiling effects. The four dimensions obtained seem relevant and presented good face validity. The dimensions were confirmed in the Swedish sample. The Satisfaction with Life Scale shows satisfactory psychometric properties and seems valid and useful among first-episode psychosis patients.

  3. Heat cost in a Swedish agrothermal plant

    International Nuclear Information System (INIS)

    Christensen, J.

    1978-01-01

    Low-grade heat is of rapidly increasing importance in Sweden and, therefore, so is the economic evaluation of such heat. The present heat cost is based on a detailed feasibility study of large-scale heated horticulture combined with electricity production from a Swedish boiling water reactor power plant. To estimate judiciously the cost of heat from a dual-purpose plant--such as a large-scale horticultural installation combined with and using low-grade waste heat from an electric power plant--is an almost classical problem: a measure of arbitrarity is unavoidable. The opportunity cost approach shown has presumably some new features. It results in an estimated cost of heat delivered from the turbine condenser heater in the power plant of 1.4 $/GJ (or 6.1 Swedish Crwn/GJ) in 1980, which is less than one-third of the cost of fuel only with conventional oil-fired heaters

This study set out to examine the effects of Swedish massage on blood pressure. Healthy males were given massage treatment at the Karolinska Hospital, Stockholm, Sweden. Treatment was over a 12-week period divided into three parts, each consisting of 4 weeks. Two treatment periods contained massage treatment either on back, neck and chest (BNC), or leg, arm and face (LAF), with an in between washout period. The first treatment period with massage decreased systolic blood pressure directly after treatment (BNC: Pmassage decreased systolic (Pmassage (Pmassage on the BNC resulted in a minor decrease in blood pressure possibly due to sympathetic inhibition. It may be suggested that massage may be tried as a complementary therapy in patients suffering from increased blood pressure due to stress.

    Quinolone-resistant Escherichia coli (QREC) is common in feces from young calves, but the prevalence and genetic diversity of QREC in groups of cattle of other ages and the farm environment are unknown. The aims of the study were to obtain knowledge about the occurrence of QREC on dairy farms, the genetic diversity of QREC within and between farms, and how these relate to the number of purchased animals and geographic distances between farms. We analyzed the within-sample prevalence of QREC in individual fecal samples from preweaned dairy calves and postpartum cows and in environmental samples from 23 Swedish dairy farms. The genetic diversity of the QREC isolates on 10 of these farms was assessed. In general, QREC was more prevalent in the dairy farm environment and in postpartum cows if QREC was commonly found in calves than if QREC was rare in calves. In particular, we found more QREC organisms in feed and water troughs and in environments that may come into contact with young calves. Thus, the results suggest that QREC circulates between cattle and the farm environment and that calves are important for the maintenance of QREC. Some genotypes of QREC were widespread both within and between farms, indicating that QREC has spread within the farms and likely also between farms, possibly through purchased animals. Farms that had purchased many animals over the years had greater within-farm diversity than farms with more closed animal populations. Finally, animals on more closely located farms were more likely to share the same genotype than animals on farms located far apart. This study investigates the occurrence of a specific type of antimicrobial-resistant bacterium on dairy farms. It contributes to increased knowledge about the occurrence and spread of these bacteria, and the results pave the way for actions or further studies that could help mitigate the spread of these bacteria on dairy farms and in the community as a whole.

    New spirometric reference equations for Swedish adults are required. Three different older sets of reference equations clinically used in Sweden have various drawbacks and the recently published 'The Global Lung Function 2012 (GLI) equations' have been shown not to be adequate for Swedish normal, healthy non-smokers. We have recently concluded that a piecewise linear model presented by Lubinski and Gólczewski accurately describes the distribution of spirometric variables in a large Swedish random population sample. This piecewise linear model also offers the important advantage of implementing easily physiologically interpretable coefficients. The present study aimed at presenting piecewise linear reference equations for Swedish adults based on a random population sample of 6685 individuals aged 25-75 years. Predicted normal values by the piecewise linear reference equations and lower limit normal (LLN) were compared with the three reference equations frequently used clinically in Sweden and the GLI equations. We found predicted normal values according to the present piecewise linear reference equations close to 100% predicted normal as expected, whereas the other equations either overestimated or underestimated normal subjects. Concerning LLN, the present equations, i.e. 1·645 × RSD, showed the least deviation from the expected 5% and, e.g., the GLI equations systematically identified too few subjects below LLN. We conclude that the present piecewise linear reference equations, based on a relatively large general population sample, ought to be considered for clinical use in Sweden. Application of 1·645 × RSD below predicted value gave an acceptably accurate LLN. © 2016 Scandinavian Society of Clinical Physiology and Nuclear Medicine. Published by John Wiley & Sons Ltd.

  13. Swedish reactor safety. Barsebaeck risk assessment

    International Nuclear Information System (INIS)

    1978-01-01

    probabilistic safety analysis of the Barsebaeck reactor, a Swedish-designed Boiling Water Reactor (BWR), was done using design and reliability information from Barsebaeck and similar Swedish reactors. The methodology of the Reactor Safety (WASH-1400) was employed to the extent possible to determine the probability of major accidents at Barsebaeck. It is concluded that an accident at the Barsebaeck nuclear plant could potentially affect a large segment of the population of Sweden and of neighbouring countries. The risk consists not only of potential harm to the current population, but of possible harm to future population due to the very long lives of the radioactive materials involved. However the complexity of nuclear systems, the relatively scant data base on which to make long-term predictions of equipment reliability, and little experience in accident consequences make the uncertainty bounds of this typype of studies very broad. Thus, in the end, the decision on the question of continuation of the Swedish nuclear power program must be made outside of, but with the assistance of, the technical community. The acceptance of nuclear power as an energy source in a country becomes a decision of social acceptability and, of necessity, must be made by the social structure's appointed representatives.

    Global health education is increasingly acknowledged as an opportunity for medical schools to prepare future practitioners for the broad health challenges of our time. The purpose of this study was to describe the evolution of global health education in Swedish medical schools and to assess students' perceived needs for such education. Data on global health education were collected from all medical faculties in Sweden for the years 2000-2013. In addition, 76% (439/577) of all Swedish medical students in their final semester answered a structured questionnaire. Global health education is offered at four of Sweden's seven medical schools, and most medical students have had no global health education. Medical students in their final semester consider themselves to lack knowledge and skills in areas such as the global burden of disease (51%), social determinants of health (52%), culture and health (60%), climate and health (62%), health promotion and disease prevention (66%), strategies for equal access to health care (69%) and global health care systems (72%). A significant association was found between self-assessed competence and the amount of global health education received (pcurriculum. Most Swedish medical students have had no global health education as part of their medical school curriculum.

    Agriculture is one of the most hazardous industries worldwide. The number of serious accidents on farms, despite sophisticated technology, development of effective prevention methods, and high-quality training and improved skill levels of farmers, is still very high. The purpose of this study was to develop and apply a generic farm safety protocol to hazards that have been identified in previously published literature and demonstrate the potential benefits of such a protocol with a view to raising awareness of farm safety. Hazards in agriculture were categorized, and literature highlighting the risks associated with hazards was collated. A protocol was developed and applied to establish the likelihood of a hazard causing injury and the consequence of that injury should adverse effects of hazards be realized. The results indicated farm ownership, farm being used as a primary residence, and missing rollover protective structures as the greatest farm risks with expected likelihood and extreme consequence such as death or permanent disablement. Other hazards that require immediate attention while developing mitigation strategies include accident history and existing medical conditions of the farmer, working environment (i.e., alone and isolated), water bodies in the proximity of the farm, lack of periodic machine maintenance, uncovered power take-off and other rotating parts of the tractor, missing safety decals, auger entanglements, and unprotected use of pesticides. Intervention strategies may be guided by considering the results presented in this study. Moreover, farm safety specialists should increase their efforts to promote effective injury prevention methods and enforce safe work environments. The developed protocol addresses almost all common aspects of farming hazards and can be used to mitigate risks associated with hazards in any farm setting.

    Shawon, Mohammad Hasanuzzaman

    Renewable energy has been playing an important role to meet power demand and 'Green Energy' market is getting bigger platform all over the world in the last few years. Due to massive increase in the prices of fossil fuels along with global warming issues, energy harvesting from renewable energy sources has received considerable interest, nowadays, where extensive researches are going on to ensure optimum use of renewable sources. In order to meet the increasing demand of electricity and power, integration of renewable energy is getting highest priorities around the world. Wind is one of the most top growing renewable energy resources and wind power market penetration is expected to reach 3.35 percent by 2013 from its present market of about 240 GW. A wind energy system is the most environmental friendly, cost effective and safe among all renewable energy resources available. Another promising form of renewable energy is ocean energy which covers 70 % of the earth. Ocean energy can be tapped from waves, tides and thermal elements. Offshore Wind farm (OWF) has already become very popular for large scale wind power integration with the onshore grid. Recently, marine current farm (MCF) is also showing good potential to become mainstream energy sources and already successfully commissioned in United Kingdom. However, squirrel cage induction generator (SCIG) has the stability problem similar to synchronous generator especially during fault location to restore the electromagnetic torque. Series dynamic braking resistor (SDBR) has been known as a useful mean to stabilize fixed speed wind generator system. On the other hand, doubly fed induction generator (DFIG) has the capability of coupling the control of active and reactive power and to provide necessary reactive power demand during grid fault conditions. Series dynamic braking resistor (SDBR) can also be employed with DFIG to limit the rotor over current. An integration of wind and tidal energy represents a new

  3. Whole farm quantification of GHG emissions within smallholder farms in developing countries

    2014-01-01

    The IPCC has compiled the best available scientific methods into published guidelines for estimating greenhouse gas emissions and emission removals from the land-use sector. In order to evaluate existing GHG quantification tools to comprehensively quantify GHG emissions and removals in smallholder conditions, farm scale quantification was tested with farm data from Western Kenya. After conducting a cluster analysis to identify different farm typologies GHG quantification was exercised using the VCS SALM methodology complemented with IPCC livestock emission factors and the cool farm tool. The emission profiles of four farm clusters representing the baseline conditions in the year 2009 are compared with 2011 where farmers adopted sustainable land management practices (SALM). The results demonstrate the variation in both the magnitude of the estimated GHG emissions per ha between different smallholder farm typologies and the emissions estimated by applying two different accounting tools. The farm scale quantification further shows that the adoption of SALM has a significant impact on emission reduction and removals and the mitigation benefits range between 4 and 6.5 tCO 2  ha −1  yr −1 with significantly different mitigation benefits depending on typologies of the crop–livestock systems, their different agricultural practices, as well as adoption rates of improved practices. However, the inherent uncertainty related to the emission factors applied by accounting tools has substantial implications for reported agricultural emissions. With regard to uncertainty related to activity data, the assessment confirms the high variability within different farm types as well as between different parameters surveyed to comprehensively quantify GHG emissions within smallholder farms.

    2016-03-01

    Full Text Available Data Farming is a process that has been developed to support decision-makers by answering questions that are not currently addressed. Data farming uses an inter-disciplinary approach that includes modeling and simulation, high performance computing, and statistical analysis to examine questions of interest with a large number of alternatives. Data farming allows for the examination of uncertain events with numerous possible outcomes and provides the capability of executing enough experiments so that both overall and unexpected results may be captured and examined for insights. Harnessing the power of data farming to apply it to our questions is essential to providing support not currently available to decision-makers. This support is critically needed in answering questions inherent in the scenarios we expect to confront in the future as the challenges our forces face become more complex and uncertain. This article was created on the basis of work conducted by Task Group MSG-088 “Data Farming in Support of NATO”, which is being applied in MSG-124 “Developing Actionable Data Farming Decision Support for NATO” of the Science and Technology Organization, North Atlantic Treaty Organization (STO NATO.

    The siting of wind farms is becoming an increasingly important issue in the Netherlands. This paper gives an overview of the current situation concerning the planning of wind farms. We will pay attention to: Wind energy in official Dutch planning policy. To select the optimal sites, the government has made an administrative agreement with the 7 windy provinces. Nevertheless, wind energy is still fighting for a rightful position in physical planning policy. Some examples will illustrate this. Studies on siting and siting problems in the Netherlands. In order to gain more insight into aspects of wind farming several studies have been executed. In this paper special attention will be paid to the results of a study on the potential impact of large windturbine clusters on an existing agricutural area. Experiences with siting of wind farms in the Netherlands. Based on experiences with the planning and realization of farms, this paper gives the main problems. In the final part of the paper we present some general conclusions. Generally speaking, the knowledge is available for selecting optimal sites in the Netherlands. The basic problems for wind farming nowadays seem to be the visual impact and actually obtaining the ground. Nevertheless, there do seem to be enough sites for realizing the goals in the Netherlands.

    2001-03-01

    This study analyses the Swedish nuclear weapons research since 1945 carried out by the Swedish National Defence Research Establishment (FOA). The most important aspect of this research was dealing with protection in broad terms against nuclear weapons attacks. However, another aspect was also important from early on - to conduct research aiming at a possible production of nuclear weapons. FOA performed an extended research up to 1968, when the Swedish Government signed the Non-Proliferation Treaty (NPT), which meant the end of these production plans. Up to this date, five main investigations about the technical conditions were made, 1948, 1953, 1955, 1957 and 1965, which all together expanded the Swedish know-how to produce a bomb. The Swedish plans to procure nuclear weapons were not an issue in the debate until the mid 50's. The reason for this was simple, prior to 1954 the plans were secretly held within a small group of involved politicians, military and researchers. The change of this procedure did take place when the Swedish Supreme Commander in a public defence report in 1954 favoured a Swedish Nuclear weapons option. In 1958 FOA had reached a technical level that allowed the Parliament to make a decision. Two programs were proposed - the L-programme (the Loading Programme), to be used if the parliament would say yes to a production of nuclear weapons, and the S-programme (the Protection Programme), if the Parliament would say no. The debate on the issue had now created problems for the Social Democratic Government. The Prime Minister, Tage Erlander, who had earlier defended a procurement of nuclear weapons, was now forced to reach a compromise. The compromise was presented to the parliament in a creative manner that meant that only the S-programme would be allowed. The Government argued that the technical level did allow a 'freedom of action' up to at least the beginning of the 60's when Sweden was mature to make a decision on the issue

    A very large share of the total raw material potential for biogas production will be found within the agriculture. The raw material potential of manure in Sweden amounts to 4 - 6 TWh. Within the agriculture there is moreover a big potential in the form of residues from plant cultivation and non-food crops (approximately 7 TWh) that can to be used for biogas production. The potential for biogas production from only residues and manure is around 8-10 TWh. An increased biogas production within the agriculture would give significant environmental effects. Among other things manure, that today is leaking methane gas to the atmosphere, can be fermented, and trough this process the methane losses will be reduced. When the produced biogas replaces fossil fuel, an overall environmental effect will be reached, that is highly significant. This manual deals with biogas plants for agriculture and such plants that do not have extensive transports of different raw materials, as manure, wastes etc. One of the starting points for this manual's set-up is a course plan that Biogas Syd made for the courses they give to farmers, advisors and others. The manual illustrates important aspects in planning and construction of biogas plants, from raw material and technology to dimensioning of plant, use of biogas and planning of local gas grids. We also think it is important to illustrate the legislation that encompasses construction work and operation of a biogas plant. Investment costs are also illustrated, but the book does not give any extensive economic calculations, since we believe that such calculations need their own manual in the form of calculation examples, based on various conditions. The final section is called 'Biogas on farm - from idea to reality' where the entire process from analysis and pre-planning to monitoring and control of plant during operation is briefly described

  13. Swedish Chemists and Discovery of the Elements

    Science.gov (United States)

    Thomsen, Volker

    1996-10-01

    All of the elements not already known from antiquity were discovered in Europe and North America. So which country ranks number one on the discovery list? The question occurred to me while leafing through reference 1 in search of thermodynamic data on silicon. Never having seen such a tabulation, I wondered if it might prove useful in teaching. The question has a sports-related flavor that will appeal to many students. Personally, I picked England or Germany for #1. The actual result is surprising. The ranking considering only up to atomic number 103 is as follows: Note: Where two or more independent discoveries have been made, each country is credited. In the "others" category Austria and Denmark each has two discoveries. The remaining countries, with one each, are Finland, Italy, Mexico, Poland, Romania, Russia, and Spain. The high place for the USA is primarily due to the work done at Berkeley and Los Alamos on the transuranics. Without these discoveries, the US would have tied with Switzerland at three elements. Perhaps the most interesting aspect of this tabulation is that Swedish chemists have discovered the most elements. Four chemists alone account for twelve of the 20 discoveries: Baron Jöns Jakob Berzelius (1779-1848) is credited with four elements. His pupil, friend, and assistant, Carl Gustav Mosander (1797-1858) discovered three. P. T. Cleve also found three elements and Karl Wilhelm Scheele (1742-1786) discovered two. Biographical research on the Swedish chemists is a suitable assignment at the introductory level. Reasons for the predominance of Swedish chemists presents a challenging student research topic in the history of chemistry. Another interesting question at the introductory level is, transuranics aside, who discovered the most elements? At the more advanced level the question becomes, why? Literature Cited: 1. Emsley, J.

    To perform an ergonomic analysis of work and machinery-related risks in a group of Swedish older farmers, investigating farmers' attitudes and perceptions about: 1) health status and work motivation, 2) physical and cognitive workload and difficulties in the interaction with machinery and technological innovations, and 3) risks and safety practices. Nine Swedish male farmers aged 65+ were administered a semi-structured interview and a questionnaire. Participants perceived themselves as being in good health and considered farming as a good proxy of their health status. They reported an increased physical workload but did not describe any cognitive workload. Technology was reported to have low usability, and thus its benefits cannot be fully exploited. Older farmers acknowledged the existence of "new risks" related to the aging process and mainly referred to the common sense and previous experience as the best safety practices. Multilevel interventions focused on the capabilities and limits of the older farmers should be developed, involving both training activities and design solutions for the machinery that can support older farmers' health and safety.

    In recent years the agricultural sector has experienced historical levels of economic challenges. Yet, the effects of these economic conditions on the physical safety of farm work environments remain poorly understood. We studied these possible etiological relationships in a cross-sectional analysis. A baseline survey of 2390 Saskatchewan farm operations was conducted in 2007. A single respondent from each farm provided information about the farm operation, its residents, perceptions of worry surrounding farm economic conditions, and the presence of six types of physical hazards. Binomial regression analyses were used to study the focal relationships between economics and safety while simultaneously adjusting for confounders at the farm level. Farms with high perceived levels of economic worry experienced elevations in risk for: the absence of well maintained buildings (RR 1.52; 95% CI: 1.27-1.87), the absence of safety shields on combines (RR 1.41; 95% CI: 1.05-1.89), and the absence of safety shields on augers (RR 1.15; 95% CI: 1.02-1.30). No apparent differences were observed by level of economic worry for the presence of ROPS on tractors, ladder safety cages on grain bins, and barriers around water hazards. We observed that financial conditions on farms appear to contribute to the decisions that farm operators make about safety. These are not innocuous choices as they in turn affect the health and safety of the entire population that works and lives in these occupational environments. Farm operators need to be supported in decisions to invest the physical safety of their farms. They also require evidence that investments in safety are indeed economically sensible and healthy management decisions. Copyright © 2013 Elsevier Ltd. All rights reserved.

    The ability is demonstrated to calculate wind farm wakes on the basis of ambient conditions that were calculated with an atmospheric model. Specifically, comparisons are described between predicted and observed ambient conditions, and between power predictions from three wind farm wake models and power measurements, for a single and a double wake situation. The comparisons are based on performance indicators and test criteria, with the objective to determine the percentage of predictions that fall within a given range about the observed value. The Alpha Ventus site is considered, which consists of a wind farm with the same name and the met mast FINO1. Data from the 6 REpower wind turbines and the FINO1 met mast were employed. The atmospheric model WRF predicted the ambient conditions at the location and the measurement heights of the FINO1 mast. May the predictability of the wind speed and the wind direction be reasonable if sufficiently sized tolerances are employed, it is fairly impossible to predict the ambient turbulence intensity and vertical shear. Three wind farm wake models predicted the individual turbine powers: FLaP-Jensen and FLaP-Ainslie from ForWind Oldenburg, and FarmFlow from ECN. The reliabilities of the FLaP-Ainslie and the FarmFlow wind farm wake models are of equal order, and higher than FLaP-Jensen. Any difference between the predictions from these models is most clear in the double wake situation. Here FarmFlow slightly outperforms FLaP-Ainslie.

    2011-03-01

    Full Text Available Abstract Background Rural Australians face a higher mental health and lifestyle disease burden (obesity, diabetes and cardiovascular disease than their urban counterparts. Our ongoing research reveals that the Australian farming community has even poorer physical and mental health outcomes than rural averages. In particular, farm men and women have high rates of overweightness, obesity, abdominal adiposity, high blood pressure and psychological distress when compared against Australian averages. Within our farming cohort we observed a significant association between psychological distress and obesity, abdominal adiposity and body fat percentage in the farming population. Presentation of hypothesis This paper presents a hypothesis based on preliminary data obtained from an ongoing study that could potentially explain the complex correlation between obesity, psychological distress and physical activity among a farming population. We posit that spasmodic physical activity, changing farm practices and climate variability induce prolonged stress in farmers. This increases systemic cortisol that, in turn, promotes abdominal adiposity and weight gain. Testing the hypothesis The hypothesis will be tested by anthropometric, biochemical and psychological analysis matched against systemic cortisol levels and the physical activity of the subjects. Implications of the hypothesis tested Previous studies indicate that farming populations have elevated rates of psychological distress and high rates of suicide. Australian farmers have recently experienced challenging climatic conditions including prolonged drought, floods and cyclones. Through our interactions and through the media it is not uncommon for farmers to describe the effect of this long-term stress with feelings of 'defeat'. By gaining a greater understanding of the role cortisol and physical activity have on mental and physical health we may positively impact the current rates of psychological

    Good animal health is a notion that is germane to organic dairy production, and it is expected that such herds would pay significant attention on the health of their animals. However, it is not known if the applied animal disease management is actually more adequate in organic dairy cattle herds than in conventional dairy herds. A questionnaire study on biosecurity and animal disease management activities was therefore conducted among Swedish farmers with organic and conventional dairy cattle herds. A total of 192 useable questionnaires were returned; response rates of 30.3 and 20.2% for organic and conventional farmers, respectively. Herd characteristics of the two herd types were very similar, except that pipeline/tie-stall systems were less common in organic farms and that organic farmers had a higher education level than their conventional counterparts. Also, very few systematic differences in general or specific disease management activities were observed between the two types of farms. The main exceptions being how milk from cows during antibiotic treatment was used, views on policy actions in relation to antibiotic use, and attitudes towards calling for veterinary support. Using milk from cows during antibiotic treatment was more common in conventional herds, although it was mainly given to bull calves. Farmers of organic herds were more positive to policy actions to reduce the use and need for antibiotics, and they reported waiting longer before contacting a veterinarian for calves with diarrhoea and cows with subclinical mastitis. The stated biosecurity and animal disease management was relatively equal in Swedish organic and conventional dairy herds. Our results thus indicate that animal health is as important in conventionally managed dairy herds in Sweden as in organically managed herds.

    Full Text Available Several studies have quantified the energy consumption associated with crop production in various countries. However, these studies have not compared the energy consumption from a broad range of farming practices currently in practice, such as zero tillage, conventional tillage and irrigated farming systems. This study examines direct on-farm energy use for high value grain crops grown under different farming practices in Australia. Grain farming processes are identified and “typical” farming operation data are collected from several sources, including published and unpublished literature, as well as expert interviews. The direct on-farm energy uses are assessed for 27 scenarios, including three high value grain crops―wheat, barley and sorghum―for three regions (Northern, Southern and Western Australia under three farming conditions with both dryland (both for conventional and zero-tillage and irrigated conditions. It is found that energy requirement for farming operations is directly related to the intensity and frequency of farming operations, which in turn is related to tillage practices, soil types, irrigation systems, local climate, and crop types. Among the three studied regions, Western Australia requires less direct on-farm energy for each crop, mainly due to the easily workable sandy soils and adoption of zero tillage systems. In irrigated crops, irrigation energy remains a major contributor to the total on-farm energy demand, accounting for up to 85% of total energy use.

    The exposure to agrochemicals during farming activities affects the function of the reproductive system, as revealed by the increasing worldwide evidence of male infertility amongst farmers. The main objective of this study was to untangle the link between agricultural practices and male reproductive impairment due to chronic exposure to xenobiotics (such as agrochemicals) in conventional and organic farming environments. For this purpose, male wild mice (Mus musculus) populations from sites representing two distinct farming practices (conventional and organic farming systems) were used as bioindicators for observable effects of testicular damage, namely on a set of histological and cellular parameters: (i) relative volumetric density of different spermatogenic cells and interstitial space; (ii) damage in the seminiferous tubules and (iii) apoptotic cells in the germinal epithelium. Results showed that mice from the conventional farming site bioaccumulated higher Pb hepatic loads, while mice from the organic farming site tend to bioaccumulate higher Cd hepatic loads. In general, for the analyzed testicular damage related parameters, mice from the organic farming site showed a similar performance than mice from the reference site. Mice from the conventional farming site stood out not only by underperforming in most studied parameters, while displaying an association between Pb hepatic loads and the observed testicular structural and functional disruption, but also by the increased stress index (Integrated Biomarker Response value). This study highlights the potential damaging effects of conventional farming practices on testicular structure and function, under natural conditions, raising concern about ensuing fertility risks for farmers.

    2017-12-01

    Full Text Available Previous research has documented lower disability retirement and mortality rates of Swedish speakers as compared with Finnish speakers in Finland. This paper is the first to compare the two language groups with regard to the receipt of sickness allowance, which is an objective health measure that reflects a less severe poor health condition. Register-based data covering the years 1988-2011 are used. We estimate logistic regression models with generalized estimating equations to account for repeated observations at the individual level. We find that Swedish-speaking men have approximately 30 percent lower odds of receiving sickness allowance than Finnish-speaking men, whereas the difference in women is about 15 percent. In correspondence with previous research on all-cause mortality at working ages, we find no language-group difference in sickness allowance receipt in the socially most successful subgroup of the population.

    2009-07-01

    "The Good Work" (Det goda arbetet) was established as a highly praised and established concept in the Swedish working life debate in the middle of the 1980s. In this paper, we are going to discuss the concept in relation to the massive introduction of lean production in Swedish industry. The aim of this paper is to restore the theory of the good work into the industrial society of today. We will search for a model for 'good work' in balance between the demands from production and good conditions for a learning environment. The theoretical base for this paper will be found in both organisational research and research on production technology systems. We identify three strong trends in Swedish industrial companies giving both pitfalls and possibilities for the good work; the learning focus as a way to increase productivity and improve working conditions; Lean Production in most cases imply narrow short-cyclic work tasks; and the global market that reduces national discretion. As a result, we formulate a new set of criteria for "the good work".

  5. Environmental Orientation in Swedish Local Governments

    Directory of Open Access Journals (Sweden)

    2018-02-01

    Full Text Available This study explores the environmental orientation in Swedish local governments. Environmental concerns over potential risk factors have become more important and popular among public organizations and environmental improvement efforts are made to create a sustainable ecosystem for the actors doing business, living and working in the area. Prior research indicates that public organizations have started to become more environmentally oriented in order to take on more responsibilities for reducing their own environmental impact as well as influencing the citizens and local businesses in the direction of a more sustainable way of living and working. Through a survey of Swedish local governments we conclude that they are taking on a key role in developing a sustainable ecosystem through becoming more environmentally oriented. This includes developing a framework for setting environmental goals, identifying suitable environmental indicators and reporting to a wide range of stakeholders. A factor that explains the increasing environmental orientation in the public sector is the implementation of digitalized performance measurement systems. We find that the environmental performance measurements are used to motivate different internal and external stakeholders in the efforts to create a multi-actor ecosystem.

    The following systems and facilities are currently in operation and under implementation: a sea transportation system for all kinds of nuclear waste, a central facility for interim storage of spent fuel (CLAB) and a central underground repository for final disposal of low and medium level reactor waste (SFR). For the remaining steps - final disposal of highly active and longlived radioactive residues - a concept, based on encapsulation of the fuel elements in copper canisters and final storage of the canisters in a repository situated 500 m down in crystalline rock (KBS-3), has been developed and approved by the government in accordance with the Swedish nuclear legislation. Although a feasible method for final disposal of the highly active residues has been shown, the Swedish legislation requires that research be carried out to reach the best possible base for the final decision around the year 2000. In parallel with this a geological investigation programme is carried out to find a suitable site for a final repository. The final site selection is foreseen at the end of the 1990's. All costs for the management of radioactive waste from the nuclear power plants are carried by a fee determined annually. The fee is 0.019 SEK/kWh for 1986

  10. Modelling Farm Animal Welfare

    Science.gov (United States)

    Collins, Lisa M.; Part, Chérie E.

    2013-01-01

    Simple Summary In this review paper we discuss the different modeling techniques that have been used in animal welfare research to date. We look at what questions they have been used to answer, the advantages and pitfalls of the methods, and how future research can best use these approaches to answer some of the most important upcoming questions in farm animal welfare. Abstract The use of models in the life sciences has greatly expanded in scope and advanced in technique in recent decades. However, the range, type and complexity of models used in farm animal welfare is comparatively poor, despite the great scope for use of modeling in this field of research. In this paper, we review the different modeling approaches used in farm animal welfare science to date, discussing the types of questions they have been used to answer, the merits and problems associated with the method, and possible future applications of each technique. We find that the most frequently published types of model used in farm animal welfare are conceptual and assessment models; two types of model that are frequently (though not exclusively) based on expert opinion. Simulation, optimization, scenario, and systems modeling approaches are rarer in animal welfare, despite being commonly used in other related fields. Finally, common issues such as a lack of quantitative data to parameterize models, and model selection and validation are discussed throughout the review, with possible solutions and alternative approaches suggested.

    To investigate the use of data from national quality registries (NQRs) in local quality improvement as well as purported key factors for effective clinical use in Sweden. Comparative descriptive: a web survey of all Swedish hospitals participating in three NQRs with different levels of development (certification level). Heads of the clinics and physician(s) at clinics participating in the Swedish Stroke Register (Riksstroke), the Swedish National Registry of Gallstone Surgery and Endoscopic Retrograde Cholangiopancreatography (GallRiks) and the Swedish Lung Cancer Registry (NLCR). Individual and unit level use of NQRs in local quality improvement, and perceptions on data quality, organizational conditions and user motivation. Riksstroke data were reported as most extensively used at individual and unit levels (x̅ 17.97 of 24 and x̅ 27.06 of 35). Data quality and usefulness was considered high for the two most developed NQRs (x̅ 19.86 for Riksstroke and x̅ 19.89 for GallRiks of 25). Organizational conditions were estimated at the same level for Riksstroke and GallRiks (x̅ 12.90 and x̅ 13.28 of 20) while the least developed registry, the NLCR, had lower estimates (x̅ 10.32). In Riksstroke, the managers requested registry data more often (x̅ 15.17 of 20). While there were significant differences between registries in key factors such as management interest, use of NQR data in local quality improvement seems rather prevalent, at least for Riksstroke. The link between the registry's level of development and factors important for routinization of innovations such as NQRs needs investigation. © The Author 2017.

  13. Outbreaks of Influenza A Virus in Farmed Mink (Neovison vison) in Denmark: Molecular characterization of the involved viruses

    DEFF Research Database (Denmark)

    Larsen, Lars Erik; Breum, Solvej Østergaard; Trebbien, Ramona

    Influenza in mink (Neovison vison) is assumed to be rare, but outbreaks have previously been reported in farmed mink. The first report was from Swedish mink farms in 1984 and the second was reported from Canadian mink farms. In 2009, influenza A of the subtype H3N2 was detected in several Danish...... or was circulating in Danish pigs. In 2010 and 2011, influenza virus was again diagnosed in diseased mink in a few farms. The genetic typing showed that the virus was similar to the pandemic H1N1 virus circulating in humans and swine. The H3N2 virus was not detected in 2010 and 2011. Taken together, these findings...

  14. Transfer of 137Cs from Chernobyl debris and nuclear weapons fallout to different Swedish population groups.

    Data from measurements on the body burden of (134)Cs, (137)Cs and (40)K in various Swedish populations between 1959 and 2001 has been compiled into a national database. The compilation is a co-operation between the Departments of Radiation Physics in Malmö and Göteborg, the National Radiation Protection Authority (SSI) and the Swedish Defense Research Agency (FOI). In a previous study the effective ecological half time and the associated effective dose to various Swedish populations due to internal contamination of (134)Cs and (137)Cs have been assessed using the database. In this study values of human body burden have been combined with data on the local and regional ground deposition of fallout from nuclear weapons tests (only (137)Cs) and Chernobyl debris (both (134)Cs and (137)Cs), which have enabled estimates of the radioecological transfer in the studied populations. The assessment of the database shows that the transfer of radiocesium from Chernobyl fallout to humans varies considerably between various populations in Sweden. In terms of committed effective dose over a 70 y period from internal contamination per unit activity deposition, the general (predominantly urban) Swedish population obtains 20-30 microSv/kBq m(-2). Four categories of populations exhibit higher radioecological transfer than the general population; i.) reindeer herders ( approximately 700 microSv/kBq m(-2)), ii.) hunters in the counties dominated by forest vegetation ( approximately 100 microSv/kBq m(-2)), iii.) rural non-farming populations living in sub-arctic areas (40-150 microSv/kBq m(-2)), and iv.) farmers ( approximately 50 microSv/kBq m(-2)). Two important factors determine the aggregate transfer from ground deposition to man; i.) dietary habits (intakes of foodstuff originating from natural and semi-natural ecosystems), and ii.) inclination to follow the recommended food restriction by the authorities. The transfer to the general population is considerably lower

  15. Shrimp Farms, Ecuador

    2006-01-01

    In many parts of the world, wetlands are being converted to shrimp ponds in order to farm these crustaceans for food and sale. One example is on the west coast of Ecuador, south of Guayaquil. The 1991 Landsat image on top shows a coastal area where 143 square kilometers of wetlands were converted to shrimp ponds. By the time ASTER acquired the bottom image in 2001, 243 square kilometers had been converted, eliminating 83% of the wetlands. These scenes cover an area of 30 x 31 km, and are centered near 3.4 degrees south latitude and 80.2 degrees west longitude. With its 14 spectral bands from the visible to the thermal infrared wavelength region, and its high spatial resolution of 15 to 90 meters (about 50 to 300 feet), ASTER images Earth to map and monitor the changing surface of our planet. ASTER is one of five Earth-observing instruments launched December 18, 1999, on NASA's Terra satellite. The instrument was built by Japan's Ministry of Economy, Trade and Industry. A joint U.S./Japan science team is responsible for validation and calibration of the instrument and the data products. The broad spectral coverage and high spectral resolution of ASTER provides scientists in numerous disciplines with critical information for surface mapping, and monitoring of dynamic conditions and temporal change. Example applications are: monitoring glacial advances and retreats; monitoring potentially active volcanoes; identifying crop stress; determining cloud morphology and physical properties; wetlands evaluation; thermal pollution monitoring; coral reef degradation; surface temperature mapping of soils and geology; and measuring surface heat balance. The U.S. science team is located at NASA's Jet Propulsion Laboratory, Pasadena, Calif. The Terra mission is part of NASA's Science Mission Directorate.

    2006-01-01

    The fact that Sweden has been spared from war on its soil for almost 200 years, has not stopped Swedish citizens from participating in conflicts worldwide during this period. This has been described, especially from the soldiers perspective. The contribution of Swedish physicians has not been written about to the same extent. When Mussolini's Italy in October 1935 invaded the poor and underdeveloped country of Ethiopia (former Abyssinia) an ambulance was immediately organized by the Swedish Red Cross. To lead such an expedition, a great knowledge of Ethiopian culture och maybe most importantly, of the weather and geographical conditions, was undoubtedly demanded. Therefore, the Swedish Red Cross turned to two Ethiopian veterans. Doctor Fride Hylander, a missionary-son who had been working on a hospital project in the Ethiopian province of Harrar and his friend since school years, doctor Gunnar Agge, were assigned the leadership of the ambulance. Dr Agge had also participated in improving the Ethiopian health care both in Harrar and later as civilian and military doctor in the province of Ogaden, where he was medically responsible for the more than 9 000 men strong army that the Ethiopian emperor had stationed there after Italian provocations. Most of the other members of the ambulance were handpicked by these two leaders and many of them had, just like themselves, a stong religious belief. A money-raise was immediately initiated and in less than six weeks 700 000 Swedish crowns had been collected, more then twice the sum the ambulance was calculated to cost. In early november 1935 the ambulance was clear to go. Their primary objective was to travel through British Somaliland and establish a field-hospital in the province of Harrar. However, the Ethiopian emperor had other things in mind. He wanted to reorganize the ambulance and divide it in two and place it closer to the front line. The ambulance decided to go along with his wish. Both groups started eventually

  18. Safety and Radiation Protection at Swedish Nuclear Power Plants 2005

    2006-05-15

    In 2005, no severe events occurred which challenged the safety at the Swedish nuclear power plants. However, some events have been given a special focus. The 'Gudrun' storm, which occurred in January 2005, affected the operation of the reactors at Ringhals and Barsebaeck 2. At Ringhals, the switchyards were affected by salt deposits and, at Barsebaeck, the 400kV grid was subjected to interruptions. The long-term trend is that the total number of fuel defects in Swedish reactors is decreasing. The damage that occurs nowadays has mainly been caused by small objects entering the fuel via the coolant and fretting holes in the cladding. To reduce the number of defects of this type, fuel with filters is successively being introduced to prevent debris from entering the fuel assemblies and cyclone filters in the facility which cleans the coolant. Since the mid-nineties, the pressurised water reactors, Ringhals 2, 3 and 4, have had problems with fuel rod bowing in excess of the safety analysis calculations. Ringhals AB (RAB) has adopted measures to rectify the bowing. Follow-up work shows that the fuel rod bowing is decreasing. The followup in 2005 of damaged tubes in the Ringhals 4 steam generators indicates a continued slow damage propagation. Tubes with defects of such a limited extent that there are adequate margins to rupture and loosening have been kept in operation. Damaged tubes with insufficient margins have plugged. During the year, previously observed minor leakage from the reactor containment in Ringhals 2 was investigated in greater detail and repaired. The investigations showed extensive corrosion attack caused by deficiencies in connection with containment construction. The ageing of electrical cables and other equipment in the I-C systems has been examined by SKI. Regulatory supervision has so far shown that these issues are largely handled in a satisfactory manner by the licensees but that certain supplementary investigations and other measures

    We estimate jointly three types of discrete-choice labor decisions of farm couples: farm work, off-farm work, and hired farm labor. Using a 16-choice multinomial logit model, we find that operators' and spouses' farm labor are substitutes. Hired farm labor increases with farmers' qualifications, perhaps substituting for the couples' labor inputs. Other adults in the households substitute for the farm labor input of the farm couple and hired workers.

    Despite similar living conditions among the Finnish-speaking majority and the Swedish-speaking minority in Finland, the latter is a more advantaged group e.g. in terms of socioeconomic status and health. This study investigated (1) the level of sense of coherence (SOC), (2) the structure of generalized resistance resources (GRRs), and (3) associations of GRRs with SOC among Finnish- and Swedish-speaking Finns. The data derived from the Health and Social Support (HeSSup) Study. The sample comprised 22,937 Finnish men and women aged 20-54, including an additional sample from the Swedish-speaking population (n = 2,967). The response rate was 40%. Ordinary regression analysis was used. Swedish-speaking women scored 0.9 (p = 0.005) and men 0.6 (p = 0.05) points higher on SOC scale compared with Finnish-speaking respondents. The minor difference in the SOC level between the language groups was explained by Finnish speakers' worse psychosocial living conditions in childhood and working conditions in adulthood. Only one interaction was found: parents' divorce during childhood was associated with a significant decrease of SOC scores only for Finnish speakers. Otherwise the same GRRs had similar effects on both Finnish- and Swedish-speaking men's and women's SOC. The only key difference between Finnish- and Swedish-speaking Finns concerned the unequal distribution of GRRs. An increase in GRRs among Finnish speakers would probably strengthen their SOC. However, the slightly stronger level of SOC among Swedish-speaking compared with Finnish-speaking Finns is unlikely to explain the possible differences in well-being between the two language groups.

    Phosphorus (P) losses from dairy farms can severely damage aquatic ecosystems, so it is important to have tools to assess overfeeding of P. This study screened P intake and faecal excretion of different P fractions in dairy cows on conventional and organic farms, compared the P feeding level of the herds against the recommendations and analysed different sampling and analysis methods for assessing the general status of P feeding on the farms. The organic (n=14) and conventional farms (n=15) were of comparable size and were located in southern Sweden. On each farm, feed intake was registered for 10 cows representing four different lactation stages and their P intake was calculated and related to current recommendations. Faecal samples taken from the same cows were analysed for total P (TP) and soluble P. Milk production data for the cows were obtained from the Swedish official milk recording scheme. TP was determined in one slurry sample per farm. More than 70% of the cows studied, representing both conventional and organic herds, consumed P in excess of the recommendations. Conventional herds had higher P content in the ration than organic herds, and lactating cows in conventional herds had higher faecal concentrations of total and soluble P than those in organic herds. However in dry cows, the P content of the ration and soluble P and TP in faeces did not differ between the two management systems. Soluble P was well correlated to TP in faeces, and both were good indicators of P overfeeding.

    This report concerning Swedish nuclear waste management has been produced as part of a cross national research project: CARL - A Social Science Research Project into the Effects of Stakeholder involvement on Decision-Making in Radioactive Waste Management. Besides Sweden, the participating countries are Belgium, Canada, Finland, Slovenia and United Kingdom. A social science research team, working for three years, is in the first phase conducting research in their own countries in order to produce 6 country reports. During the next years the focus will shift to comparisons of stakeholder involvement practices in the participating countries. The report addresses current practices of Swedish nuclear waste management and their historical development. The main focus is on past, current and emerging patterns of stakeholder involvement in the siting of a deep repository for the final disposal of Sweden's spent nuclear fuel. The general questions attended to in the report are: Who are the main stakeholders, and how have they emerged and gained recognition as such? What are the issues currently subject to stakeholder involvement and how have these been decided upon? How is stakeholder involvement organized locally and nationally and how has this changed over time? How has stakeholder involvement gained acceptance as an activity of value in the siting of major waste facilities? The report have attempted to show the development of stakeholder involvement in the siting of a final repository for Sweden's spent nuclear fuel as resembling something other than a straightforward linear process of improvement and refinement. Stakeholder involvement has developed, over the past 15 years or so, into something more like a patchwork of different shapes and forms. Some of the forces that may well contribute to the further elaboration of the patchwork of stakeholder involvement have been pointed out, contingently modifying once more its overall colour and orientation.

    2014-01-01

    Altogether, 369 pathogenic Yersinia enterocolitica isolates from 1,118 fecal samples collected from 22 pig farms of different production types were characterized by biotyping, serotyping, and genotyping using multiple-locus variable-number tandem repeats analysis. We investigated the distribution of the different genotypes at the farm level and their association with different farm conditions. Pigs were found to carry and transmit Y. enterocolitica between farms, because the same genotypes were found on farms that had previously transported the pigs between them. The purchase of new animals for the farms associated significantly with the number of different multiple-locus variable-number tandem repeats analysis types of Y. enterocolitica found within a farm. Some genotypes seemed to persist on farms for years. The results of this study show that pigs purchased from infected herds transmit Y. enterocolitica infection between farms. Certain pig farms may act as long-term sources of infection.

    Full Text Available This paper examines the development of taxation in Sweden from 1862 to 2010. The examination includes six key aspects of the Swedish tax system, namely the taxation of labor income, capital income, wealth, inheritances and gifts, consumption and real estate. The importance of these taxes varied greatly over time and Sweden increasingly relied on broad-based taxes (such as income taxes and general consumption taxes and taxes that were less visible to the public (such as payroll taxes and social security contributions. The tax-to-GDP ratio was initially low and relatively stable, but from the 1930s, the ratio increased sharply for nearly 50 years. Towards the end of the period, the tax-to-GDP ratio declined significantly.

    Mass media are influential mediators of information, knowledge, and narratives of health and illness. In this article, we report on an examination of personal accounts of illness as presented in three Swedish newspapers, focusing on the gendered representation of laypersons' experiences of depression. A database search identified all articles mentioning depression during the year 2002. Twenty six articles focusing on personal experiences of depression were then subjected to a qualitative content analysis. We identified four themes: displaying a successful facade, experiencing a cracking facade, losing and regaining control, and explaining the illness. We found both similarities and differences with regard to gendered experiences. The mediated accounts of depression both upheld and challenged traditional gender stereotypes. The women's stories were more detailed, relational, emotionally oriented, and embodied. The portrayal of men was less emotional and expressive, and described a more dramatic onset of depression, reflecting hegemonic patterns of masculinity.

    During 1997 the PWRs in Ringhals performed extremely well (capability factors 85-90%), the unit Ringhals 2 reached the best capability factor since commercial operation started in 1976. The BWRs made an average 76% capability, which is somewhat less than in 1996. The slightly reduced capability derives from ongoing modernization projects at several units. At the youngest plants, Forsmark 3 and Oskarshamn 3, capability and utilization were very high. Events and data for 1997 are given for each reactor, together with operational statistics for the years 1990-1997. A number of safety-related events are reported, which occurred st the Swedish plants during 1997. These events are classified as level 1 or higher on the international nuclear event scale (INES).

    This study identified perceived employability trajectories and their associations with sleeping difficulties and depressive symptoms over time. The sample was part of the Swedish Longitudinal Survey on Health from 2008 to 2014 (n=4,583). Two stable trajectories (high and low perceived employability over time) and three trajectories with changes (increasing, decreasing, and V-shaped perceived employability over time) were identified. Workers with stable low perceived employability reported more sleeping difficulties and depressive symptoms than those who perceived high or increasing employability. Perceived employability is a rather stable personal resource, which is associated with well-being over time. However, changes in perceived employability do not seem to be echoed in well-being, at least not as immediately as theoretically expected.

    Full Text Available This article is a reflection of cultural differences recorded by the author during her research visit to Sweden in the year 2017 (February-March month. The objectives of the research visit included understanding official dialects of both countries, existing education system and work environments, variant food habits, family structure and associations, available transport systems, sustainable living options and cultural exchange within India and Sweden. The information was first collected through existing literature and was supported by information collected through observation method, informal discussions and interactions with the Swedish people. It can be concluded that both countries are culturally very different and different parts of each country further exhibit alteration in cultural practices, languages and food preferences. Some variations are also due to population size in both countries. For instance, transportation is very well developed in developed countries due to the availability of advanced technology and less population.

  11. Energy balance in olive oil farms: comparison of organic and conventional farming systems.

    Moreno, Marta M.; Meco, Ramón; Moreno, Carmen

    2013-04-01

    The viability of an agricultural production system not only depends on the crop yields, but especially on the efficient use of available resources. However, the current agricultural systems depend heavily on non-renewable energy consumption in the form of fertilizers, fossil fuels, pesticides and machinery. In developed countries, the economic profitability of different productive systems is dependent on the granting of subsidies of diverse origin that affect both production factors (or inputs) and the final product (or output). Leaving such external aids, energy balance analysis reveals the real and most efficient form of management for each agroclimatic region, and is also directly related to the economic activity and the environmental state. In this work we compare the energy balance resulting from organic and conventional olive oil farms under the semi-arid conditions of Central Spain. The results indicate that the mean energy supplied to the organic farms was sensitively lower (about 30%) in comparison with the conventional management, and these differences were more pronounced for the biggest farms (> 15 ha). Mean energy outputs were about 20% lower in the organic system, although organic small farms (benefits it provides, which are not usually considered in the conventional management on not valuing the damage it produces to the environment. Organic farming would improve the energy efficiency in these environmental conditions, offering a sustainable production with minimal inputs.

  12. Perspectives on implementing energy efficiency in existing Swedish detached houses

    International Nuclear Information System (INIS)

    Joelsson, Anna; Gustavsson, Leif

    2008-01-01

    In this study, we first analyse energy-efficiency measures in existing electrically heated houses in Sweden from a societal economic perspective. Measures to a house envelopes and to energy supply chains are evaluated through a system analysis approach and we include the external costs of climate change and the effect of different Swedish climatic zones. We find that in a typical house from the 1970s, conversion from electric heating is highly motivated since the mitigation cost of conversion is lower than the estimated external costs of emitted CO 2 . Both conversions and house envelope measures are more motivated in the northern part of the country, where there is a higher heat demand. A successful implementation of changes requires them to be attractive for consumers to adopt. We therefore secondly analyse the economic conditions for Swedish house owners to implement societal economic cost-efficient measures. We include the economic influence of an investment subsidy for heating system conversion, an income tax deduction for changing windows, customer electricity tax, real estate tax and of the cost of purchased energy from different energy suppliers. Apart from the economics, several other factors affect a house owner's decision to change heating systems. We therefore thirdly analyse house owners' perceptions of different heating supply alternatives based on the results of two comprehensive questionnaires. These different perspectives are combined in a discussion whether the studied policy instruments encourage house owners to implement changes in accordance with the energy-efficiency goals of decision makers. We find that the investment subsidy could be useful to break the lock-in effect of resistance heaters, which house owners seemed to experience. The electricity tax makes heating systems in line with national goals more competitive and efficiency measures to the house envelope more profitable. The reduction of the electricity tax in the northern part of

    Background To clarify the role of genetic and environmental factors in criminal behavior (CB), we examined all CB and violent and non-violent subtypes (VCB and NVCB, respectively) in a Swedish national sample of adoptees and their relatives. Method CB was defined by a conviction in the Swedish Crime Register with standard definitions for VCB and NVCB subtypes. We examined adoptees born 1950–1991 (n=18070) and their biological (n=79206) and adoptive (n=47311) relatives. Results The risk for all CB was significantly elevated in the adopted-away offspring of biological parents of which at least one had CB [odds ratio (OR) 1.5, 95% confidence interval (CI) 1.4–1.6] and in the biological full and half-siblings of CB adoptees (OR 1.4, 95% CI 1.2–1.6 and OR 1.3, 95% CI 1.2–1.3, respectively). A genetic risk index (including biological parental/sibling history of CB and alcohol abuse) and an environmental risk index (including adoptive parental and sibling CB and a history of adoptive parental divorce, death, and medical illness) both strongly predicted probability of CB. These genetic and environmental risk indices acted additively on adoptee risk for CB. Moderate specificity was seen in the transmission of genetic risk for VCB and NVCB between biological parents and siblings and adoptees. Conclusions CB is etiologically complex and influenced by a range of genetic risk factors including a specific liability to CB and a vulnerability to broader externalizing behaviors, and by features of the adoptive environment including parental CB, divorce and death. Genetic risk factors for VCB and NVCB may be at least partially distinct. PMID:24180693

    Swedish nuclear power plants have over the last 20 years of operation modernised or exchanged several systems and components of the electrical power system. Within these works, new components based on digital technology have been employed in order to realize functionality that was previously achieved by using electro-mechanical or analogue technology. Components and systems such as relay protection, rectifiers, inverters, variable speed drives and diesel-generator sets are today equipped with digital components. Several of the systems and components fulfil functions with a safety-role in the NPP. Recently, however, a number of incidents have occurred which highlight deficiencies in the design or HMI of the equipment, which warrants questions whether there are generic problems with some applications of digital components that needs to be addressed. The use of digital components has presented cost effective solutions, or even the only available solution on the market enabling a modernisation. The vast majority of systems using digital components have been operating without problems and often contribute to improved safety but the challenge of non-detectable, or non-identifiable, failure modes remain. In this paper, the extent to which digital components are used in Swedish NPP power systems will be presented including a description of typical applications. Based on data from maintenance records and fault reports, as well as interviews with designers and maintenance personnel, the main areas where problems have been encountered and where possible risks have been identified will be described. The paper intends to investigate any 'tell-tales' that could give signals of unwanted behaviour. Furthermore, particular benefits experienced by using digital components will be highlighted. The paper will also discuss the safety relevance of these findings and suggest measures to improve safety in the application of digital components in power systems. (authors)

    Solomon, Morse B.; Eastridge, Janet S.; Paroczay, Ernest W.

    Conventional science to improve muscle and meat parameters has involved breeding strategies, such as selection of dominant traits or selection of preferred traits by cross breeding, and the use of endogenous and exogenous hormones. Improvements in the quality of food products that enter the market have largely been the result of postharvest intervention strategies. Biotechnology is a more extreme scientific method that offers the potential to improve the quality, yield, and safety of food products by direct genetic manipulation. In the December 13, 2007 issue of the Southeast Farm Press, an article by Roy Roberson pointed out that biotechnology is driving most segments of U.S. farm growth. He indicated that nationwide, the agriculture industry is booming and much of that growth is the result of biotechnology advancements.

  17. Particularities of farm accounting

    Directory of Open Access Journals (Sweden)

    Lapteș, R.

    2012-01-01

    Full Text Available Nowadays, agriculture has become one of the most important fields of activity, significant funds being allotted within the EU budget to finance the European agriculture. In this context, organising the accounting of economic entities which carry out their activity in the agricultural sector has acquired new meanings. The goal of the present study is to bring into the light the particularities of the farm accounting on two levels: on the one hand, from the perspective of the international accounting referential and, on the other hand, in compliance with the national accounting regulations. The most important conclusion of this work is that, in post-1990 Romania, no interest was further manifested for the refinement of aspects specific to farm accounting.

    The objective of this study was to estimate the prevalence of current asthma and the proportion of current asthma that is related to work on the farm among primary farm operators. The 2011 Farm and Ranch Safety Survey data were used to produce estimates and prevalence odds ratios. An estimated 5.1% of farm operators had asthma. Of these, 15.4% had farm work-related asthma. Among operators with farm work-related asthma, 54.8% (95% confidence interval [CI]: 41.8%-68.2%) had an asthma attack in the prior 12 months and 33.3% (95% CI: 21.2%-45.4%) had an asthma attack that occurred while doing farm work. Of those who had an asthma attack that occurred while doing farm work, 65.0% associated their asthma attack with plant/tree materials. This study provides updated information on asthma and the proportion of current asthma that is related to work on the farm and identifies certain groups of farm operators that might benefit from workplace asthma prevention intervention.

    Several dairy farms in the Netherlands aim at reducing environmental impacts by improving the internal nutrient cycle (INC) on their farm by optimizing the use of available on-farm resources. This study evaluates the environmental performance of selected INC farms in the Northern Friesian Woodlands in comparison to regular benchmark farms using a Life Cycle Assessment. Regular farms were selected on the basis of comparability in terms of milk production per farm and per hectare, soil type and drainage conditions. In addition, the environmental impacts of INC farming at landscape level were evaluated with the integrated modelling system INITIATOR, using spatially explicit input data on animal numbers, land use, agricultural management, meteorology and soil, assuming that all farms practised the principle of INC farming. Impact categories used at both farm and landscape levels were global warming potential, acidification potential and eutrophication potential. Additional farm level indicators were land occupation and non-renewable energy use, and furthermore all farm level indicators were also expressed per kg fat and protein corrected milk. Results showed that both on-farm and off-farm non-renewable energy use was significantly lower at INC farms as compared with regular farms. Although nearly all other environmental impacts were numerically lower, both on-farm and off-farm, differences were not statistically significant. Nitrogen losses to air and water decreased by on average 5 to 10% when INC farming would be implemented for the whole region. The impact of INC farming on the global warming potential and eutrophication potential was, however, almost negligible (cycle. Copyright © 2015 Elsevier B.V. All rights reserved.

    Full Text Available Dynamic simulation of sustainable farm development scenarios using cognitive modeling. The paper presents a dynamic simulation system of sustainable development scenarios on farms using cognitive modeling. The system incorporates relevant variables which affect the sustainable development of farms. Its user provides answers to strategic issues connected with the level of farm sustainability over a long-term perspective of dynamic development. The work contains a description of the model structure as well as the results of simulations carried out on 16 farms in northern Ukraine. The results show that the process of sustainability is based mainly on the potential for innovation in agricultural production and biodiversity. The user is able to simulate various scenarios for the sustainable development of a farm and visualize the influence of factors on the economic and social situation, as well as on environmental aspects. Upon carrying out a series of simulations, it was determined that the development of farms characterized by sustainable development is based on additional profit, which serves as the main motivation for transforming a conventional farm into a sustainable one. Nevertheless, additional profit is not the only driving force in the system of sustainable development. The standard of living, market condition, and legal regulations as well as government support also play a significant motivational role.

  2. Possibilities of implementing nitrogen removal at Swedish wastewater treatment plants

    International Nuclear Information System (INIS)

    Hultman, Bengt; Plaza, Elzbieta; Tendaj-Xavier, Marta

    1987-01-01

    Problems related to eutrophication and oxygen consumption have been considered as the major factors in deterioration of the water quality in Swedish lakes, rivers and coastal areas. Technical solutions to reduce oxygen-consuming materials and eutrophication have up to now been directed towards the removal of biochemical oxygen demand (BOD) and phosphorus. Thus, biological and chemical treatment of municipal wastewater is usually prescribed, and at present about 90% of the municipal wastewater from Swedish urban areas is treated both biologically and chemically. Most plants are designed for post-precipitation, although the treatment plants may now be operated in a modified way, for example, with the use of preprecipitation, two-point precipitation or recirculation of chemical sludges. Hultman and Moore (1982) have presented an overview of Swedish practice in municipal wastewater treatment. Although Swedish treatment of municipal wastewater concentrates on the removal of biochemical oxygen demand and phosphorus, the environmental and operational effects of nitrogen have been discussed for many years

    If farmers are risk averse, greater farm income variability should increase off-farm labor supply. This effect is confirmed for a sample of Kansas farmers. Off-farm employment of farmers and their spouses is also found to be significantly influenced by farm experience, off-farm work experience, farm size, leverage, efficiency, and farm-specific education. In addition, farm operators and spouses who receive significant income support through government farm programs are less likely to work off...

  4. Sweden and the bomb. The Swedish plans to acquire nuclear weapons, 1945 - 1972

    International Nuclear Information System (INIS)

    Jonter, T

    2001-09-01

    This study analyses the Swedish nuclear weapons research since 1945 carried out by the Swedish National Defence Research Establishment (FOA). The most important aspect of this research was dealing with protection in broad terms against nuclear weapons attacks. However, another aspect was also important from early on - to conduct research aiming at a possible production of nuclear weapons. FOA performed an extended research up to 1968, when the Swedish government signed the Non-Proliferation Treaty (NPT), which meant the end of these production plans. Up to this date, five main investigations about the technical conditions were made, 1948, 1953, 1955, 1957 and 1965, which all together expanded the Swedish know-how to produce a bomb. The Swedish plans to procure nuclear weapons were not an issue in the debate until the mid-50's. The reason for this was simple, prior to 1954 the plans were secretly held within a small group of involved politicians, military and researchers. The change of this procedure did take place when the Swedish Supreme Commander in a public defence report in 1954 favoured a Swedish Nuclear weapons option. In 1958 FOA had reached a technical level that allowed the parliament to make a decision. Two programs were proposed - the L-programme (the Loading Programme), to be used if the parliament would say yes to a production of nuclear weapons, and the S-programme (the Protection Programme), if the parliament would say no. The debate on the issue had now created problems for the Social Democratic Government. The prime minister, Tage Erlander, who had earlier defended a procurement of nuclear weapons, was now forced to reach a compromise. The compromise was presented to the parliament in a creative manner that meant that only the S-programme would be allowed. The government argued that the technical level did allow a 'freedom of action' up to at least the beginning of the 60's when Sweden was mature to make a decision on the issue. During this period

  9. Farming practices in Sweden related to feeding milk and colostrum from cows treated with antimicrobials to dairy calves

    Science.gov (United States)

    2013-01-01

    Background Milk produced by cows in receipt of antimicrobial therapy may contain antimicrobial residues. Such antimicrobial-containing waste milk must be withdrawn from human consumption and is therefore sometimes used as calf feed. Unfortunately, this approach might promote selection of antimicrobial resistant bacteria in the calves’ intestinal microbiota. The objectives of this study were therefore to obtain an overview of waste milk feeding practices on Swedish dairy farms and to investigate if these practices were associated with certain farm characteristics. A representative group of 457 Swedish dairy farmers participated in a web-based survey with questions about the use of colostrum and milk from cows treated with antimicrobials at dry off or during lactation, respectively, as calf feed. Results Colostrum (milk from the first milking after calving) and transition milk (milk from the second milking to the fourth day after calving) from cows treated with antimicrobials at dry off was fed to calves on 89% and 85% of the farms in the study, respectively. When antimicrobial therapy was given to cows during lactation, 56% of the farms fed milk that was produced during the course of treatment to calves, whereas milk that was produced during the subsequent withdrawal period was fed to calves on 79% of the farms. Surveyed farmers were less prone to feed such milk if the antimicrobial therapy was due to mastitis than other infections. In Sweden, a majority of antimicrobial treatments during lactation are systemic administration of benzylpenicillin and thus, the bulk of waste milk in Sweden is likely to contain residues of this drug. Feeding waste milk to calves was more common on non-organic farms, and on farms located in Southern Sweden, and was less common on farms with cows housed in cold free stalls barns. Conclusions Waste milk that may contain antimicrobial residues is, at least occasionally, used as feed for calves on a majority of surveyed Swedish dairy

    2003-05-01

    This paper studies the Swedish component suppliers in the wind power industry. This group has not received much attention so far, and today very little is known. This study addresses the fact that the Swedish component suppliers have not been able to penetrate the wind power market despite the Swedish industry's strength in mechanical and electrical engineering. The aims of this paper were to gather information regarding the existing production and to identify factors that affect the Swedish component suppliers' scope to penetrate the wind turbine market. To date, although Sweden has spent considerable amounts of money on projects involving wind turbines, there is no series production of large wind turbines in Sweden. The historical development of the wind turbine industry suggests this alone would have inhibited the development of component production in Sweden. Yet, the country's proximity and good access to large wind turbine producing countries should be an advantage. Various factors and issues are identified and discussed in this paper that are relevant for the Swedish component suppliers' scope to penetrate the wind turbine market. These include market and product development, buyer-supplier relationships, export and sourcing behaviors, and time of market entry. This is a first step towards increasing the knowledge of Swedish component production and it is recognized that more studies are required. Various areas where relevant knowledge is largely missing or scarce are identified and discussed as well, and should serve as relevant starting points for continued research.

    2008-11-01

    The objective of this study was to investigate the relationship between managerial leadership and self-reported sickness absence/presenteeism among Swedish men and women. Five thousand one hundred and forty-one Swedish employees, 56% of the participants in a nationally representative sample of the Swedish working population, were included in this cross-sectional questionnaire study. The leadership dimensions measured were five subscales of a standardized leadership questionnaire (Global Leadership and Organizational Behaviour Effectiveness Programme): Integrity, Team integration, Inspirational leadership, Autocratic leadership, and Self-centred leadership. Multiple logistic regression analyses were conducted, adjusting for factors in private life, employment category, labour-market sector, working conditions, self-reported general health, and satisfaction with life in general. Inspirational leadership was associated with a lower rate of short spells of sickness absence (leadership was related to a greater amount of total sick days taken by men. Sometimes showing integrity was associated with higher rate of sickness absence >1 week among men, and seldom showing integrity was associated with more sickness presenteeism among women. Managers performing Team integration were sometimes associated with women taking fewer short (1 week) spells of sickness absence. Adjustment for self-reported general health did not alter these associations for men, but did so to some extent for women. Managerial leadership was found to be relevant for the understanding of sickness absence in the Swedish working population. There were distinctive gender differences.

  14. Soil management practices under organic farming

    Science.gov (United States)

    Aly, Adel; Chami Ziad, Al; Hamdy, Atef

    2015-04-01

    Organic farming methods combine scientific knowledge of ecology and modern technology with traditional farming practices based on naturally occurring biological processes. Soil building practices such as crop rotations, intercropping, symbiotic associations, cover crops, organic fertilizers and minimum tillage are central to organic practices. Those practices encourage soil formation and structure and creating more stable systems. In farm nutrient and energy cycling is increased and the retentive abilities of the soil for nutrients and water are enhanced. Such management techniques also play an important role in soil erosion control. The length of time that the soil is exposed to erosive forces is decreased, soil biodiversity is increased, and nutrient losses are reduced, helping to maintain and enhance soil productivity. Organic farming as systematized and certifiable approach for agriculture, there is no surprise that it faces some challenges among both farmers and public sector. This can be clearly demonstrated particularly in the absence of the essential conditions needed to implement successfully the soil management practices like green manure and composting to improve soil fertility including crop rotation, cover cropping and reduced tillage. Those issues beside others will be fully discussed highlighting their beneficial impact on the environmental soil characteristics. Keywords: soil fertility, organic matter, plant nutrition

  15. Disease eradication on large industrial farms.

    Rozins, Carly; Day, Troy

    2016-10-01

    Many modern farms exhibit all-in-all-out dynamics in which entire cohorts of livestock are removed from a farm before a new cohort is introduced. This industrialization has enabled diseases to spread rapidly within farms. Here we look at one such example, Marek's disease. Marek's disease is an economically important disease of poultry. The disease is transmitted indirectly, enabling the spread of disease between cohorts of chickens who have never come into physical contact. We develop a model which allows us to track the transmission of disease within a barn and between subsequent cohorts of chickens occupying the barn. It is described by a system of impulsive differential equations. We determine the conditions that lead to disease eradication. For a given level of transmission we find that disease eradication is possible if the cohort length is short enough and/or the cohort size is small enough. Marek's disease can also be eradicated from a farm if the cleaning effort between cohorts is large enough. Importantly complete cleaning is not required for eradication and the threshold cleaning effort needed declines as both cohort duration and size decrease.

    2011-01-01

    Swedish voters' support for the labor movement has decreased from about 50 percent to less than 40 percent in recent decades, with a resulting loss of the majority in parliament. Over the same period, capitalism has undergone profound changes--transfer of production across borders, the huge growth and ultra-rapid movement of financial capital, and subordination of social welfare to the interests of profit. A new phase in the development of capitalism can be detected: from welfare capitalism to financial capitalism. Large parts of the public sector have been privatized by both conservative and labor governments, even while retaining public funding. The social gaps grow, and a new line of conflict is emerging in the values and interests that should govern care-taking, schools, and living conditions. The labor movement's ideological and scientific analyses have taken a backseat to liberal-conservative think tanks. An effective response to financial capitalism, transnational production chains, and European integration will require trade union and political actions across national borders to strengthen the power resources in the hands of the majority of the population, so as to counter the increasingly destructive powers of capitalism.

  19. Are large farms more efficient? Tenure security, farm size and farm efficiency: evidence from northeast China

    2017-04-01

    How to increase production efficiency, guarantee grain security, and increase farmers' income using the limited farmland is a great challenge that China is facing. Although theory predicts that secure property rights and moderate scale management of farmland can increase land productivity, reduce farm-related costs, and raise farmer's income, empirical studies on the size and magnitude of these effects are scarce. A number of studies have examined the impacts of land tenure or farm size on productivity or efficiency, respectively. There are also a few studies linking farm size, land tenure and efficiency together. However, to our best knowledge, there are no studies considering tenure security and farm efficiency together for different farm scales in China. In addition, there is little study analyzing the profit frontier. In this study, we particularly focus on the impacts of land tenure security and farm size on farm profit efficiency, using farm level data collected from 23 villages, 811 households in Liaoning in 2015. 7 different farm scales have been identified to further represent small farms, median farms, moderate-scale farms, and large farms. Technical efficiency is analyzed with stochastic frontier production function. The profit efficiency is regressed on a set of explanatory variables which includes farm size dummies, land tenure security indexes, and household characteristics. We found that: 1) The technical efficiency scores for production efficiency (average score = 0.998) indicate that it is already very close to the production frontier, and thus there is little room to improve production efficiency. However, there is larger space to raise profit efficiency (average score = 0.768) by investing more on farm size expansion, seed, hired labor, pesticide, and irrigation. 2) Farms between 50-80 mu are most efficient from the viewpoint of profit efficiency. The so-called moderate-scale farms (100-150 mu) according to the governmental guideline show no

    Full Text Available Wood farming is one of the strategies of agricultural development programs to reform unsustainable exploitation of natural resources. Poplar is one of the known species for wood farming in the country. This species is fast-growing and has numerous Colognes has the ability to adapt to different climatic conditions. Fast growth, good economic returns and traditional agricultural knowledge, favorable habitat to agriculture are advantages of poplar for agricultural development. However, the result of previous studies indicates existing barriers to the development of plantation and its development need strategic planning. What seem essential today are strategies to overcome these obstacles. Accordingly, this present study with a holistic view trying to identify the strengths, weaknesses, opportunities and threats of poplar farming. And the most appropriate strategies for the development of poplar farming in Urmia have offered. This research was a Field study and conducted using questionnaires. In this study, strategies were defined using SWOT analysis and the strategies were prioritized using analysis network process. The results showed the history of poplar farming in this region is the most important benefit to development and the many uses for poplar wood is the next priority. Increasingly replacement of poplar farming with alternative cultures is one of the main weaknesses of poplar farming development in this region. After that long return of profitability in poplar farming is the second priority. The most important opportunities for the development were the development of credit specialists to support of poplar farming and the most important threat was lack of annual financing of farmers. Also the results of strategic prioritization showed, Modern irrigation methods to reduce water consumption and planning to teach correct principles of technical planting, farming and harvesting are considered as the most important strategies.

    Full Text Available Among hereditary colorectal cancer predisposing syndromes, Lynch syndrome (LS caused by mutations in DNA mismatch repair genes MLH1, MSH2, MSH6 or PMS2 is the most common. Patients with LS have an increased risk of early onset colon and endometrial cancer, but also other tumors that generally have an earlier onset compared to the general population. However, age at first primary cancer varies within families and genetic anticipation, i.e. decreasing age at onset in successive generations, has been suggested in LS. Anticipation is a well-known phenomenon in e.g neurodegenerative diseases and several reports have studied anticipation in heritable cancer. The purpose of this study is to determine whether anticipation can be shown in a nationwide cohort of Swedish LS families referred to the regional departments of clinical genetics in Lund, Stockholm, Linköping, Uppsala and Umeå between the years 1990-2013. We analyzed a homogenous group of mutation carriers, utilizing information from both affected and non-affected family members. In total, 239 families with a mismatch repair gene mutation (96 MLH1 families, 90 MSH2 families including one family with an EPCAM-MSH2 deletion, 39 MSH6 families, 12 PMS2 families, and 2 MLH1+PMS2 families comprising 1028 at-risk carriers were identified among the Swedish LS families, of which 1003 mutation carriers had available follow-up information and could be included in the study. Using a normal random effects model (NREM we estimate a 2.1 year decrease in age of diagnosis per generation. An alternative analysis using a mixed-effects Cox proportional hazards model (COX-R estimates a hazard ratio of exp(0.171, or about 1.19, for age of diagnosis between consecutive generations. LS-associated gene-specific anticipation effects are evident for MSH2 (2.6 years/generation for NREM and hazard ratio of 1.33 for COX-R and PMS2 (7.3 years/generation and hazard ratio of 1.86.

    In Scandinavia seismic activity is generally low. Only a few incidents have been registered in historic time, which might have damaged an industrial plant of today. There has been no earthquakes in Sweden strong enough to affect a NPP during our nuclear era (and not for very long time before either). So the risk for an nuclear accident i Sweden, caused by an earthquake, may thus be considered to be low. The basis and the methodology used in the design of Forsmark 3 and Oskarshamn 3 with respect to seismic safety is not in all parts suited to be employed for the older reactors. The methods implies a number of simplifications which may be a practical approach in connection with a new design but which might cause too conservative judgements of existing designs. The development of methods is therefore a vital part in the analysis. The Swedish nuclear Power Inspectorate (SKI), Vattenfall AB, Sydkraft AB and Oskarshams Kraftgrupp AB (OKG) have performed such a development of methods in a joint research program: `Project Seismic Safety`. The aim of the project was to develop methods for calculating the ground response to be used in the safety analysis of nuclear power plants in Sweden, as well as to demonstrate its application to the power plants at Ringhals and Barseback. The study also included a survey of geological and seismological conditions in the regions around the power plants studied. Since the large scale geological and seismological conditions around the individual nuclear plant sites are not very different as regards their expected effects on the seismic ground motion, the results obtained for the `typical hard rock site` can be taken as a basis for the characterization of the ground motions at the individual sites, after appropriate transformations to account for specific load conditions, seismological as well as geological.

    In the large fabric of society, the energy system interacts with many other things, and these in turn are interdependent. A solution to the energy problem can therefore not be found in isolation. The proposal made in this book is that the best future mainstay of energy supply in the United States is methanol, eventually to be produced entirely from biomass. This will solve not only the problems of energy supply and vulnerable oil imports but also the farm problems of surplus production, low prices, and soil erosion and the ecological ones of air pollution and eventual overheating of the atmosphere

  8. The Swedish nuclear industry way to approach higher demands on characterisation prior to clearance

    International Nuclear Information System (INIS)

    2012-01-01

    The Swedish Radiation Safety Authority (SSM) has introduced new regulations for clearance SSMFS 2011:2 'Regulations concerning clearance of material, rooms, buildings and soil from activities with ionizing radiation'. The new regulations came into force January 1, 2012. Compared to the previous regulations these new regulations have a broader scope and have introduced new conditions such as nuclide specific clearance levels. Clearance is practiced to reduce the amount of radioactive waste generated. Cleared material can be reused, recycled or if these two possibilities are not available, disposed of as conventional waste. To be able to meet the requirements for clearance the Swedish nuclear industry has jointly developed guidance for clearance in the form of a handbook and a training course covering the competence requirements in the new regulations. The handbook was developed by a team of representatives from the Swedish nuclear license holders managed by Studsvik on behalf of Swedish Nuclear Fuel and Waste Management Company (SKB). The training program was developed in co-operation between Nuclear Safety and training Company (KSU) and Studsvik on behalf of the Swedish nuclear license holders. A major challenge in the adoption to the new regulations is how to provide robust yet cost effective characterisation data. This is especially difficult for mobile materials and equipment which cannot be fully tracked but also for other materials and areas where the nuclide fingerprint has varied over the years. To be able to deal with these issues a lot of attention has to be paid to the historical inventory records and traceability in the clearance process. Materials, rooms and buildings have been divided in four categories with different requirements on frequency and requirements of measurements. The categories are named 'extremely small risk', 'small risk', 'risk' and 'known contamination above clearance levels'. The two day training course is dived into seven parts

    Psychiatric rehabilitation supports individuals with mental disorders to acquire the skills needed for independent lives in communities. This article assesses the potential of outsourcing psychiatric rehabilitation by analysing care farm services in the Netherlands. Service characteristics were analysed across 214 care farms retrieved from a national database. Qualitative insights were provided by five case descriptions, selected from 34 interviews. Institutional care farms were significantly larger and older than private care farms (comprising 88.8% of all care farms). Private, independent care farms provide real-life work conditions to users who are relatively less impaired. Private, contracted care farms tailor the work activities to their capacities and employ professional supervisors. Institutional care farms accommodate for the most vulnerable users. We conclude that collaborations with independent, contracted and institutional care farms would provide mental health care organizations with a diversity in services, enhanced community integration and a better match with users' rehabilitation needs.

    The occupational radiation doses at Swedish NPPs have decreased with roughly a factor of two from the beginning of the 1990's until today. The average collective dose during the last five years is 10 manSv for eleven operating reactors. During the same period, the average annual individual dose to the personnel has decreased from 3 - 4 mSv/year to about 2 mSv/year. In this presentation, the measures taken to improve the radiological conditions at the NPPs are briefly reviewed and the present status is described. The expectations for the future are outlined. The SSI summarises past experiences and the prerequisites for preserving good radiation protection conditions by the following catch words: Competence, Experience Feedback, Preventive Measures, and Long-Term Planning. Finally, it is the view of the SSI that essential efforts to improve the radiation protection conditions at the Swedish nuclear power plants have been made. The radiation protection conditions are good, which is a result of long-term efforts on reducing radiation levels, improving work procedures as well as increasing the knowledge of, and the commitment to, radiation protection issues at the staff level.

    2011-03-01

    Full Text Available The aim of this work is to assess the flexibility of production allowed by extensive production conditions faced with variations in the environment, i.e., market variations and climatic fluctuations, of Limousin beef systems. The study used a case-based methodology in which seven beef farms with less than 1 LU/ha were chosen. Data collection was based on three interviews using a semistructured questionnaire and on the analysis of productive and economic results over a 15-year period (1991-2005. The main evolution of these farms is related to a rise in work productivity associated with an increase in herd size. Herd increase was made possible by enlarging the area, the margin of intensification being limited in these regions. To take advantage of the enlarged land area, females were reared for fattening or for reproduction instead of selling them at weaning. The Limousin female provides a wide product mix because of its plasticity, as has been studied by several researchers. This mix flexibility is achieved by delaying product differentiation, a form of production flexibility that can reduce the risk of under-producing or over-producing varied product configurations. On the other hand, calves sold to the Italian market after weaning are generic products, associated with a flexible production process to overcome fluctuations in forage availability due to climatic variations. The introduction of maize silage for feeding acts as an alternative route, actual and potential, through the system to overcome unexpected forage shortage from natural grasslands as a result of droughts. The study shows that extensive farming systems have developed types of flexibility to match different factors of uncertainty from the environment. Finally, the issue of farm system performance is thus not so much a question of whether a farm is fit at a specific moment in time, but whether it transforms into a less or more sustainable orientation.

    To assess the characteristics of occupational and leisure farm injuries in Greece. During a five-year period (1996-2000), 4,326 unintentional farm injuries have been recorded by the Emergency Department Injury Surveillance System in Greece. Data concerning demographic variables, accident conditions, and injury characteristics were collected by in person interviews. The data were analyzed by simple cross-tabulation and hierarchical cluster analysis. Injuries from falls on the same level are mainly lower-limb fractures and occur during the winter among older women. Falls from higher level concern migrant workers, who also tend to suffer severe multiple injuries, including concussions, particularly during autumn. Injuries resulting from cutting and piercing instruments, as well as from machinery, are generally open wounds in the upper-limbs, suffered by young migrant workers. Head injuries resulting from striking against an object are more generally spread across socio-demographic variables. Overexertion is the dominant mechanism for dislocations and sprains in the lower limbs. Snake and insect bites are common among younger migrant workers during summer, and they affect the upper limbs during manual work close to the ground. Non-traffic injuries from vehicles are frequently severe, involving head concussion of generally young individuals. In Greece, farm injuries are frequently serious and require hospitalization. These injuries show distinct patterns among older women (lower-limb fractures), young individuals (non-traffic vehicle-related injuries) and migrant workers (injuries from cutting and piercing instruments, falls from high level, and bites). Prevention strategies should give priority to these population groups. These prevention strategies should include guidance for poorly educated workers, including migrants, enforcement of safety regulations concerning farming machinery, and discouragement of risky farming activities among elderly individuals, particularly

    The relatively high gender equality in the Swedish society is likely to exert an influence on gender role construction. Hence, the present research aimed to investigate Swedish women's perceptions of and conformity to feminine norms. A mixed methods approach with two studies was used. In Study 1, young Swedish women's gender role conformity, as measured by the Conformity to Feminine Norms Inventory 45 (CFNI-45), was compared to the results from previously published studies in Canada, the United States, and Slovakia. Overall, Swedish women displayed less conformity than their foreign counterparts, with the largest difference on the subscale Sexual fidelity. In Study 2, focus group interviews with young Swedish women added a more complex picture of feminine norms in the Swedish society. For instance the results indicated that Swedish women, while living in a society with a strong gender equality discourse, are torn between the perceived need to invest in their appearances and the risk of being viewed as non-equal when doing so. In sum, despite the fact that traditional gender roles are less pronounced in Sweden, gender role conformity is still a pressing issue. Since attending to the potential roles of feminine norms in women's lives previously has been proposed to be useful in counseling and therapeutic work, the present research also offers valuable information for both researchers and practitioners.

    1977-01-01

    In view of the present nuclear programmes a steep increase in uranium demand is foreseen which will pose serious problems for the uranium industry. The annual additions to uranium ore reserves must almost triple within the next 15 years in order to support the required production rates. Although there are good prospects for the discovery of further conventional deposits of uranium there is a growing interest in low grade uranium deposits. Large quantities of uranium exist in black shales, phosphates, granites, sea water and other unconventional sources. There are however factors which limit the utilization of these low grade materials. These factors include the extraction costs, the environmental constrains on mining and milling of huge amounts of ore, the development of technologies for the beneficiation of uranium and, in the case of very low grade materials, the energy balance. The availability of by-product uranium is limited by the production rate of the main product. The limitations differ very much according to types of ores, mining and milling methods and the surroundings. As an illustration a description is given of the Swedish Ranstad uranium shale project, its potential, constraints and technical solutions

    Full Text Available The present study investigated workplace incivility in a Swedish context. The first aim was to assess how common the phenomenon is and the second was to study which groups (gender, age, ethnicity, and power position are most targeted by workplace incivility and are more prone to act in an uncivil way. Additionally, the relationships between experienced and witnessed incivility and wellbeing as well as instigated incivility were investigated. An online survey was administered by SIFO (the national public opinion poll agency. The collected data consist of a stratified sample whose composition is identical to the working population in Sweden (N = 3001. The results show that almost three quarters of the respondents had been the target of coworker incivility and 52% of supervisor incivility at least one to two times in the past year. Of the respondents, 75% had witnessed coworkers and 58% witnessed a supervisor treating others in an uncivil way. Furthermore, 66% had instigated uncivil acts toward others. The results also show that female and younger employees are slightly more targeted by incivility from coworkers and younger employees and supervisors are slightly more prone to instigate incivility. Moreover, it was found that that experienced incivility was the strongest predictor of low well-being and that witnessed incivility was the strongest predictor of instigated incivility.

    There is a lack of knowledge about the incidence of personality disorders and their consequences among peacekeepers. Moreover, most studies are follow-up studies in which, if at all, personality traits are screened for after the soldiers have left their service abroad. The aim of this paper was to study personality disorders in a longitudinal perspective. The method used was to screen the personnel in a Swedish mechanized battalion serving in Bosnia from March until October 1996 on four occasions: before deployment, immediately after deployment, 6 months after deployment and 1 year after deployment. Serving in the battalion were 724 individuals of whom 516 took part in the survey. The screening instrument used was the DSM-IV and ICD-10 Personality Questionnaire (DIP-Q). The result shows that the rate of personality disorders were on the same level, or a little bit lower, than in the general population. Moreover, personality disorders were related to impaired general mental health and to reported traumatic experiences. Personality disorders also seemed to contribute to poor mental health 1 year after returning home from a mission abroad. The implications of these results for the future selection of peacekeepers are discussed.

    Small-scale enterprises are less often covered by occupational health services and have insufficient awareness about health and risks in the work environment. This study investigated how Swedish entrepreneurs in small-scale enterprises use occupational health services. The study used a questionnaire sent in two waves, 5 years apart. At baseline, 496 entrepreneurs responded, and 251 participated 5 years later. The questionnaire included items about affiliation with and use of occupational health services, physical and psychosocial work environments, work environment management, sources of work environment information, and membership in professional networks. Only 3% of entrepreneurs without employees and 19% of entrepreneurs with employees were affiliated with an occupational health service. Entrepreneurs affiliated with occupational health services were more active in work environment management and gathering information about the work environment. The occupational health services most used were health examinations, health care, and ergonomic risk assessments. Affiliation with occupational health services was 6% at both measurements, 4% at baseline, and 10% 5 years later. 2011, SLACK Incorporated.

    Full Text Available Integrated Pest Management based on Farmer Field Schools (IPM/FFS is a program aimed to guide farmers toward managing agricultural pests in an environmentally responsible manner. This program has been in practice during the recent decade in the north of Iran. A study was conducted to evaluate the overall impacts of IPM/FFS program on energy balance and economic revenue of paddy (Oryza sativa L. farms compared with conventional farms (no IPM. The data of inputs, management practices, and output (yield of 238 paddy farms (135 IPM farms and 103 conventional farms located in a semi-Mediterranean climate were collected in 2010 and 2011. Total energy input, energy output, energy efficiency, and energy productivity were determined as indicators of energy balance. The total energy requirement for paddy production in IPM system was 48756 MJ ha−1, indicating that 8% more energy was used in IPM farms than that in conventional farms. It was noticed that IPM program in this region failed to reduce the consumption of chemical pesticides in paddy farms and the conventional system was more energy efficient than IPM system. Although paddy yield of the two systems was similar, the economic net return in IPM system was almost 20% higher than the conventional system due to the higher price of paddy produced in IPM system.

    At a national level, planning and management of dental services should be based on assess- ments of equity, effectiveness and costs. In Sweden, data for the adult population are now acces- sible through The Swedish dental health register, at The National Board of Health and Welfare. This study, on two large cohorts of Swedish adults, is based on longitudinal follow-up data, retrieved from the Swedish dental health register.The aims were twofold: to assess frequencies and costs of fillings and crowns, including subsequent repair; secondly to study the relationship between preventive and restorative dental treatment.The Swedish dental health register pro- vides data on the adult population which offers a new perspective on public health aspects of management of dental care at the national level. A longitudinal, prospective study model was used to follow-up two large cohorts for over four years. In the first cohort, data on 1,088,923 adult patients were analysed with reference to provision of single crowns and fillings over a period of 42 -48 months.The second cohort comprised 1,703,147 adult patients: the data were analysed with reference to preventive interventions over a period of 48 - 54 months. Frequencies of distribution of dental care by age group showed that the cohorts were representative for the whole patient group.With respect to equity, the average number of dentist appointments per i,ooo inhabitants for all 21 regions of Sweden was 140 to 160, despite major variations in geographic conditions and population densities. With respect to effectiveness, about 76% of the teeth with index interven- tions required no additional intervention over four consecutive years of follow-up. For the remain- ing 24% of the teeth 77% had only one additional intervention. When differences of case-mix were taken into account, the costs of repairs to earlier ihterventions were basically similar, regardless of age-group.There were no gender differences. However, there were

    The Eating Disorder Inventory-3 (EDI-3) is designed to assess eating disorder psychopathology and the associated psychological symptoms. The instrument has been revised and has not yet been validated for Swedish conditions in its current form. The aim of this study was to investigate the validity and reliability of this inventory and present national norms for Swedish females. Data from patients with eating disorders (n = 292), psychiatric outpatients (n = 140) and normal controls (n = 648), all females, were used to study the internal consistency, the discriminative ability, and the sensitivity and specificity of the inventory using preliminary cut-offs for each subscale and diagnosis separately. Swedish norms were compared with those from Denmark, USA, Canada, Europe and Australian samples. The reliability was acceptable for all subscales except Asceticism among normal controls. Analysis of variance showed that the EDI-3 discriminates significantly between eating disorders and normal controls. Anorexia nervosa was significantly discriminated from bulimia nervosa and eating disorder not otherwise specified on the Eating Disorder Risk Scales. Swedish patients scored significantly lower than patients from other countries on the majority of the subscales. Drive for Thinness is the second best predictor for an eating disorder. The best predictor for anorexia nervosa was Interoceptive Deficits and Bulimia for the other diagnoses. Conclusions/clinical implications: The EDI-3 is valid for use with Swedish patients as a clinical assessment tool for the treatment planning and evaluation of patients with eating-related problems. However, it still exist some uncertainty regarding its use as a screening tool.

The paper specially focus on the impact of the regulations and the recommendations that phytotherapeutic essences and homeopathic products take precedence over the so called chemically-synthesised allopatic veterinary medical products, and that the use of the same is prohibited for preventive treatments. Key questions here are the lack of scientific evidence concerning homeopathy in animals, and that Swedish veterinarians are not allowed to work with homeopathy. Differences in interpretation of the regulations between animal owners and veterinarians will also be discussed. What is a disease that needs treatment? Who is to decide about the treatment? Parasitic infections are discussed as an illustrative example. Other consequences of the regulations concerning the animal welfare are problems in certain geographical zones, for instance subarctic areas where necessary crops are impossible to grow. Animal transports and splitting mother-offspring are briefly discussed as future problems to be handled in the regulations, and the paper ends by presenting the need of regulated herd health control programs in organic husbandry, which can detect and focus on welfare and production problems. The organic movement is not static, and must not be so.

    Full Text Available Objective. The purpose of this pilot study was to investigate and compare the effects of reflexology and Swedish massage therapy on physiologic stress, pain, and mood in older cancer survivors residing in nursing homes. Methods. An experimental, repeated-measures, crossover design study of 18 nursing home residents aged 75 or over and diagnosed with solid tumor in the past 5 years and following completion of cancer treatments. The intervention tested was 20 minutes of Swedish Massage Therapy to the lower extremities, versus 20 minute Reflexology, using highly specified protocols. Pre- and post-intervention levels of salivary cortisol, observed affect, and pain were compared in the Swedish Massage Therapy and Reflexology conditions. Results. Both Reflexology and Swedish Massage resulted in significant declines in salivary cortisol and pain and improvements in mood. Conclusions. Preliminary data suggest that studies of Swedish Massage Therapy and Reflexology are feasible in this population of cancer survivors typically excluded from trials. Both interventions were well tolerated and produced measurable improvements in outcomes. Further research is needed to explore the mechanisms underlying the potential benefits of these CAM modalities in this patient population.

    The dynamics of turbine wakes is affected by turbine operating conditions, ambient atmospheric turbulent flows, and wakes from upwind turbines. Investigations of the wake from a single turbine have been extensively carried out in the literature. Studies on the wake dynamics in utility-scale wind farms are relatively limited. In this work, we employ large-eddy simulation with an actuator surface or actuator line model for turbine blades to investigate the wake dynamics in utility-scale wind farms. Simulations of three wind farms, i.e., the Horns Rev wind farm in Denmark, Pleasant Valley wind farm in Minnesota, and the Vantage wind farm in Washington are carried out. The computed power shows a good agreement with measurements. Analysis of the wake dynamics in the three wind farms is underway and will be presented in the conference. This work was support by Xcel Energy (RD4-13). The computational resources were provided by National Renewable Energy Laboratory.

    Full Text Available The extent of the potential health hazards of particulate matter (PM inside rabbit farms and the magnitude of emission levels to the outside environment are still unknown, as data on PM concentrations and emissions in and from such buildings is scarce.  The purpose of this study was to quantify airborne PM10 and PM2.5 concentrations and emissions on two rabbit farms in Mediterranean conditions and identify the main factors related with farm activities influencing PM generation.  Concentrations of PM10 and PM2.5 were determined continuously using a tapered element oscillating microbalance (TEOM in one farm with fattening rabbits and one reproductive doe farm in autumn.  At the same time as PM sampling, the time and type of human farm activity being performed was recorded. Additionally, temperature, relative humidity and ventilation rate were recorded continuously.  Emissions were calculated using a mass balance on each farm.  Results showed PM concentrations in rabbit farms are low compared with poultry and pig farms.  Average PM10 concentrations were 0.082±0.059 mg/m3 (fattening rabbits, and 0.048 ±0.058 mg/m3 (reproductive does. Average PM2.5 concentrations were 0.012±0.016 mg/m3 (fattening rabbits, and 0.012±0.035 mg/m3 (reproductive does. Particulate matter concentrations were significantly influenced by the type of human farm activity carried out in the building rather than by animal activity.  The main PM-generating activity on the fattening rabbit farm was sweeping, and the major PM-generating activity in reproductive does was sweeping and burning hair from the cages.  Average PM10 emissions were 5.987±6.144 mg/place/day (fattening rabbits, and 14.9±31.5 mg/place/day (reproductive does.  Average PM2.5 emissions were 0.20±1.26 mg/place/day (fattening rabbits, and 2.83±19.54 mg/place/day (reproductive does.  Emission results indicate that rabbit farms can be considered relevant point sources of PM emissions, comparable to

    The deregulation of the Swedish electricity market in 1996 was well known in advance, and the nuclear power plants in Sweden, as well as their main suppliers, made early preparations for a this new situation. In a study - performed by the author at Malardalen University in Sweden - it is concluded that the electricity industry, including the nuclear power plants, was fundamentally transformed in conjunction with market liberalisation. Two large foreign companies, E-on and Fortum, entered the Swedish market and became part-owners of the nuclear plants. After deregulation, the electricity market in Sweden is dominated by these two companies and the large national company Vattenfall. Similarly, Vattenfall has recently grown into an international energy company, acquiring generation capacity in Northern Europe outside of Sweden, including nuclear power plants in Germany. Restructuring of the nuclear industry on the supplier side started in the 1980's, when the Swedish company ASEA and BBC of Switzerland merged to become ABB. Several years later the Swedish nuclear plant supplier ABB-Atom became part of Westinghouse Electric Company, today owned by Toshiba. The Swedish experience thus confirms an international trend of mergers and consolidation in the nuclear industry. (authors)

    The use of measurement scales to assess pain in neonates is considered a prerequisite for effective management of pain, but these scales are still underutilised in clinical practice. The aim of this study was to describe and compare pain assessment practices including the use of pain measurement scales in Norwegian and Swedish neonatal care units. A unit survey investigating practices regarding pain assessment and the use of pain measurement scales was sent to all neonatal units in Sweden and Norway (n = 55). All Norwegian and 92% of Swedish units responded. A majority of the participating units (86.5%) assessed pain. Swedish units assessed and documented pain and used pain measurement scales more frequently than Norwegian units. The most frequently used scales were different versions of Astrid Lindgren's Pain Scale (ALPS) in Sweden and Echelle Douleur Inconfort Noveau-Ne (EDIN), ALPS and Premature Infant Pain Profile (PIPP) in Norway. Norwegian head nurses had more confidence in their pain assessment method and found the use of pain measurement scales more important than their Swedish colleagues. The persisting difference between Swedish and Norwegian units in pain assessment and the use of pain measurement scales are not easily explained. However, the reported increased availability and reported use of pain measurement scales in neonatal care units in both countries may be seen as a contribution towards better awareness and recognition of pain, better pain management and potentially less suffering for vulnerable neonates. © 2017 Nordic College of Caring Science.

  1. Demonstration and Dialogue: Mediation in Swedish Nuclear Waste Management

    International Nuclear Information System (INIS)

    Elam, Mark; Lidberg, Maria; Soneryd, Linda; Sundqvist, Goeran

    2009-01-01

    This report analyses mediation and mediators in Swedish nuclear waste management. Mediation is about establishing agreement and building common knowledge. It is argued that demonstrations and dialogue are the two prominent approaches to mediation in Swedish nuclear waste management. Mediation through demonstration is about showing, displaying, and pointing out a path to safe disposal for inspection. It implies a strict division between demonstrator and audience. Mediation through dialogue on the other hand, is about collective acknowledgements of uncertainty and suspensions of judgement creating room for broader discussion. In Sweden, it is the Swedish Nuclear Fuel and Waste Management Co. (SKB) that is tasked with finding a method and a site for the final disposal of the nation's nuclear waste. Two different legislative frameworks cover this process. In accordance with the Act on Nuclear Activities, SKB is required to demonstrate the safety of its planned nuclear waste management system to the government, while in respect of the Swedish Environmental Code, they are obliged to organize consultations with the public. How SKB combines these requirements is the main question under investigation in this report in relation to materials deriving from three empirical settings: 1) SKB's safety analyses, 2) SKB's public consultation activities and 3) the 'dialogue projects', initiated by other actors than SKB broadening the public arena for discussion. In conclusion, an attempt is made to characterise the long- term interplay of demonstration and dialogue in Swedish nuclear waste management

    Previous investigations showed that laser Raman spectroscopy (LRS) can be used as a phase specific analytical tool for radioactive fuel crud samples and also for details in the underlying layer of zirconium dioxide. It is relatively easy to record Raman spectra that discriminate between chemical phases for all crud oxides of interest. The method has therefore been recommended for crud investigations within the Swedish program. At ideal conditions the resolution is about 1 {mu}m, permitting detailed position determination of crud phases in the sample. Therefore LRS is a very good complement to X-ray diffraction (XRD). The methods for sample preparation and handling of radioactive crud samples for LRS turn out to be relatively simple. A detailed LRS study on fuel crud samples from Barsebaeck 2, Forsmark 2, Forsmark 3 and Ringhals 1 was performed in this work. All of those Swedish BWRs were operated at different conditions at the time of sampling. The chemistry regimes covered NWC, HWC and other variable conditions. Also different types of fuel, exposure times and sampling positions were selected. (authors)

    Mounting oil import bills in India are restricting her development programmes by forcing the cutting down of the import of other essential items. But the countries of the tropics have abundant sunlight and vast tracts of arable wastelands. Energy farming is proposed in the shape of energy plantations through forestry or energy cropping through agricultural media, to provide power fuels for transport and the industries and also to provide fuelwoods for the domestic sector. Short rotation cultivation is discussed and results are given of two main species that are being tried, ipil-ipil and Casuarina. Evaluations are made on the use of various crops such as sugar cane, cassava and kenaf as fuel crops together with hydrocarbon plants and aquatic biomass. (Refs. 20)

    It's July 1945. Germany is in defeat and the atomic bombs are on their way to Japan. Under the direction of Samuel Goudsmit, the Allies are holding some of the top German nuclear scientists-among them Heisenberg, Hahn, and Gerlach-captive in Farm Hall, an English country manor near Cambridge, England. As secret microphones record their conversations, the scientists are unaware of why they are being held or for how long. Thinking themselves far ahead of the Allies, how will they react to the news of the atomic bombs? How will these famous scientists explain to themselves and to the world their failure to achieve even a chain reaction? How will they come to terms with the horror of the Third Reich, their work for such a regime, and their behavior during that period? This one-act play is based upon the transcripts of their conversations as well as the author's historical work on the subject.

    Agriculture continues to rank as the most dangerous industry in the United States. The objectives of this pilot study were to identify the incidence of care provided to children involved in farm accidents, examine barriers to utilization of farm safety materiaJs by primary health care practitioners (PHCPs), and determine the percentage of PHCPs who provide anticipatory guidance related to farm safety. Pender's revised Health Promotion Model (2006) was used. A survey was developed and mailed to 110 PHCPs of all levels in North West Pennsylvania. The return rate was 20%. Types of injuries identified by the PHCPs included lacerations and musculosketal injuries caused by animals and farm equipment. Forty-five percent of the PHCPs reporting asked new patients/families if their children lived or worked on a farm. Eighteen percent specifically focused on farm-related injury prevention. Fourteen percent were aware of farm injury prevention materials and 73% were interested in receiving such materials. A larger study needs to be conducted to validate these findings.

    Low- and intermediate-level reactor waste has been produced in Sweden for many years, but only recently have plans for its final disposal been presented. According to these plans the waste will be transported from the nuclear power stations and research facilities to a final repository in hard rock under the Baltic Sea. It is anticipated that a series of waste handling and disposal operations will be commenced within the next ten years. For realization of these operations the waste forms must fulfil certain, as yet not clearly defined, quality requirements. A programme is outlined for the identification and quantification of those properties which are of importance for the safe handling, transportation and intermediate storage of the waste. The programme includes the following steps: (1) Collection of data concerning existing plant inventories (waste), raw material, solidification processes, waste composition, etc.; (2) Categorization of the waste; within each category the properties should be similar and expected to fall within certain intervals; (3) Identification of those properties which are of interest for each category with respect to both normal and abnormal handling situations; (4) Development and evaluation of methods for sampling and testing important properties; (5) Survey of existing R and D and test data, together with supplementary investigations and measurements; (6) Assessment of the properties of relevance for each waste category. This work was initiated by the Swedish Nuclear Power Inspectorate in 1981 and is being performed in close cooperation with the nuclear power industry. The results will be used by the concerned parties as a basis for the definition and stipulation of quality requirements for the various categories of waste, and the confirmation and introduction of quality control and quality assurance procedures.

    This study targets plantation forestry by farm households (small holders), which is increasing globally and most rapidly in China and Vietnam. By use of an interdisciplinary approach on three study sites in Vietnam, we examined the trends in farmers' tree planting over time, the various pre-requisites for farm-based plantation forestry and its impact on rural people's livelihood strategies, socioeconomic status, income and security. The findings indicated a change from subsistence to cash-based household economy, diversification of farmers' incomes and a transformation of the landscape from mainly natural forests, via deforestation and shifting cultivation, to a landscape dominated by farm-based plantations. The trend of transformation, over a period of some 30 years, towards cash crops and forestry was induced by a combination of policy, market, institutional, infrastructural and other conditions and the existence of professional farming communities, and was most rapid close to the industrial market.

    2008-01-01

    In the current context of soaring turbine prices, supply bottlenecks and record wind farm valuations, carefully crafted entry strategies are key to growing profitable and competitive wind portfolios. The wind energy industry is growing rapidly on the back of technological advancements, political will and government subsidies. Utility companies, independent power providers, institutional investors and oil companies are all seeking to capitalise on lucrative support mechanisms to unlock greater commercial and competitive advantages, meet their renewables targets and boost their green credentials. Strong growth therefore continues on the back of record sustainable energy investments, yet record wind-farm development costs and valuations are now driving 'dotcom' comparisons as the economics of wind farming projects come under increasing pressure. However, a new series of reports by market analyst Datamonitor reveals that wind farm projects can still be profitable and competitive under very specific financial, technical, regulatory and legislative conditions [nl

    The purpose of this handbook is to provide a structured guide for contractors interested in establishing offshore wind farms within Swedish territorial waters and its extended economical zone, in relation to Underwater Cultural Heritage (UCH). It is also applicable to UCH in inland waters. Therefore, this handbook seeks to provide information on; - The management structure of underwater/maritime cultural heritage in Sweden, including institutions and units with maritime antiquarian expertise, - The different types of archaeological remains that can be found around the Swedish coast - in offshore, coastal areas and on the foreshore - which can potentially be affected by offshore wind farm projects, - The laws that underwater archaeological remains are subject to - within the National Maritime Boundary as well as within the contiguous and exclusive economical zones - and the necessary archaeological investigations that need to be considered in order to avoid and/or protect the cultural heritage provided by those remains, - Archaeological standards and methods for assessing and evaluating the potential for finding archaeological remains under water, - The steps that need to be to considered during the planning process of establishing offshore wind farms, and how the contractor and archaeologist can work together in order to make the process more cost effective, and - Considerations for the future. Furthermore, this handbook includes a presentation of archaeological finds made during archaeological surveys in connection with the Lillgrund project. The handbook does not make references to any investigations that may be required in relation to land based archaeological sites other than those which are undertaken close to the shoreline (situated on the foreshore), nor does it consider the visual impact sea-based wind farms might have on cultural heritage

    2015-04-01

    This perspective reviews key institutional and organizational patterns in Swedish health care over the last 30 years, probing the roots of several complicated policy questions that concern present-day Swedish decision-makers. It explores in particular the ongoing structural tension between stability, on the one hand, and the necessary levels of innovation and dynamism demanded by the current period of major clinical, technological, economic, social and supranational (EU) change. Where useful, the article compares Swedish developments with those in the other three European Nordic countries as well as other northern European health systems. Sweden's health sector evolution can provide valuable insight for other countries into the complexity involved in re-thinking tradeoffs between policies that emphasize stability as against those that encourage innovation in health sector governance and provision.

    The total production of electricity from Swedish nuclear power plants was 65.6 TWh during 2002, which is a decrease compared to 2001. The energy capability factor for the 11 Swedish reactors averaged 80.8%. The PWRs at Ringhals averaged 87.6%, while the BWRs, not counting Oskarshamn 1, reached 89.2%. No events, which in accordance to conventions should be reported to IAEA, have occurred during 2002. Operational statistics are presented for each Swedish reactor. The hydroelectric power was 66 TWh, 16% lower than 2000. Wind power contributed 0.5 TWh, and remaining production sources, mainly from solid fuel plants combined with district heating, contributed 10.9 TWh. The electricity generation totalled 143 TWh, considerably less than the record high 2001 figure of 158.7 TWh. The preliminary figures for export were 14.8 TWh and and for import 20.1 TWh.

    Full Text Available The organic sector in our country, although as shown in continuous development, faces a multitude of problems: the climatic conditions of our country, characterized by periods of drought in many parts of the country, high input prices, the majority of which are imported; difficulties in identifying markets for products, reduced subsidies, standardized conditions difficult to meet, etc. The problems the sector is facing reflect in the organization of the production activity and hence the economic performance of farm production. Accordingly, the aim of this paper was to analyze on the basis of annual financial and accounting information collected in the two vegetable farms and the two animal breeding farms, their efficiency / inefficiency, and the results were compared to identify the causes of the differences obtained in the efficiency at a farm level. The results obtained reveal a higher level of return on integrated vegetable farm in a joint recovery and a high efficiency for chain integrated animal farms.

    For assessment of the possibility of the wind farm (collective wind power facility) in Japan, site conditions, business plans and various issues in development were arranged using some projects in a planning stage. The case study of a system design was also conducted for a typical site. Four sites were selected based on geographical conditions, topographic features and weather conditions. Scales of every site are as large as 1000-3000kW and 400- 750kW in wind turbine capacity. Every developer expects a subsidy, and governmental economic support is indispensable for the wind farm. In the case of Hisai city, Mie prefecture with the most favorable wind condition in Japan, the annual mean wind velocity of the site is valued at nearly 8m/s, suggesting that it is promising for the wind farm. From the planned scale of 750kWtimes4, the annual generated power and availability factor are valued at 9,800,000kWh/y and 37%, respectively. From the construction cost of 1 billion yen including a subsidy of its half, the generation cost is valued at 14.5 yen/kWh in durability of 15 years, and 12.2 yen/kWh in 20 years, and the profitability is dependent on the purchase price of a power company. 27 figs., 36 tabs.

    2014-01-01

    In the late 18th century the Horror Ballad became popular in Sweden. The rediscovery of medieval tales and ballads inspired the Romantic authors. Clas Livijn uses the medieval folksong of "Hafsfrun" in his dramatic play of the same title (1806). In Livijn’s own library we also find many......” by Baggesen, in turn based on German and English sources. Anna Maria Lenngren followed with several ballads, often based on Danish sources. One more purely Swedish medieval ballad is “Varulven”. From 1810 unto 1971 thirteen versions of this Swedish ballad was discovered and printed. I place the focus...

    In this paper we use data from the Swedish National Survey of Forest Soils and Vegetation (NSFSV) to evaluate the present acid-base status of forest soils to try to answer the following questions. Which role do anthropogenic and biological acidification play for the present acid-base status of the soil profile? What is the present acid-base status of Swedish forest soils and how large areas may be considered as severely acidified? Do the current tendencies in soil acid-base status correspond with the positive development in surface waters?

    Full Text Available In this article we compare the acquisition of determiners in bilingual children acquiring Italian simultaneously with German or Swedish. We are concerned with cross-linguistic differences in the rate of acquisition and we discuss in particular the Nominal Mapping Parameter, a model according to which the syntax-semantics interface is crucial in acquisition and which predicts similar developmental patterns for children acquiring a Germanic language. We show that Swedish determiners are acquired more easily than German determiners, which implies that predictions for developmental patterns should not be based on syntactic factors alone, but must make reference to typological differences in morphology and phonology. Furthermore, we show that the acquisition of Italian determiners is affected positively by the simultaneous acquisition of Swedish but that no such effect arises when Italian is acquired simultaneously with German.

    Full Text Available At the international policy level, there is a clear link between access to information about forests and the work towards sustainable land use. However, involving forests in planning for sustainable development (SuD at the Swedish local level, by means of municipal comprehensive planning (MCP, is complicated by sector structure and legislation. Currently, there is a gap or hole in the MCP process when it comes to use and access to knowledge about forest conditions and forest land use. This hole limits the possibilities to formulate well-informed municipal visions and goals for sustainable forest land use as well as for overall SuD. Here we introduce an approach for compilation and presentation of geographic information to increase the preconditions for integrating forest information into Swedish MCP. We produce information about forest ownership patterns and forest conditions in terms of age and significant ecological and social values in forests for a case study municipality. We conclude that it is possible to effectively compile geographic and forest-related information to fill the hole in the municipal land use map. Through our approach, MCP could be strengthened as a tool for overall land use planning and hence as a base in SuD planning.

  7. On wake modeling, wind-farm gradients, and AEP predictions at the Anholt wind farm

    2018-04-01

    Full Text Available We investigate wake effects at the Anholt offshore wind farm in Denmark, which is a farm experiencing strong horizontal wind-speed gradients because of its size and proximity to land. Mesoscale model simulations are used to study the horizontal wind-speed gradients over the wind farm. From analysis of the mesoscale simulations and supervisory control and data acquisition (SCADA, we show that for westerly flow in particular, there is a clear horizontal wind-speed gradient over the wind farm. We also use the mesoscale simulations to derive the undisturbed inflow conditions that are coupled with three commonly used wake models: two engineering approaches (the Park and G. C. Larsen models and a linearized Reynolds-averaged Navier–Stokes approach (Fuga. The effect of the horizontal wind-speed gradient on annual energy production estimates is not found to be critical compared to estimates from both the average undisturbed wind climate of all turbines' positions and the undisturbed wind climate of a position in the middle of the wind farm. However, annual energy production estimates can largely differ when using wind climates at positions that are strongly influenced by the horizontal wind-speed gradient. When looking at westerly flow wake cases, where the impact of the horizontal wind-speed gradient on the power of the undisturbed turbines is largest, the wake models agree with the SCADA fairly well; when looking at a southerly flow case, where the wake losses are highest, the wake models tend to underestimate the wake loss. With the mesoscale-wake model setup, we are also able to estimate the capacity factor of the wind farm rather well when compared to that derived from the SCADA. Finally, we estimate the uncertainty of the wake models by bootstrapping the SCADA. The models tend to underestimate the wake losses (the median relative model error is 8.75 % and the engineering wake models are as uncertain as Fuga. These results are specific for

  8. Optimization Model for Mitigating Global Warming at the Farm Scale: An Application to Japanese Rice Farms

    Directory of Open Access Journals (Sweden)

    2016-06-01

    Full Text Available In Japan, greenhouse gas emissions from rice production, especially CH4 emissions in rice paddy fields, are the primary contributors to global warming from agriculture. When prolonged midseason drainage for mitigating CH4 emissions from rice paddy fields is practiced with environmentally friendly rice production based on reduced use of synthetic pesticides and chemical fertilizers, Japanese rice farmers can receive an agri-environmental direct payment. This paper examines the economic and environmental effects of the agri-environmental direct payment on the adoption of a measure to mitigate global warming in Japanese rice farms using a combined application of linear programming and life cycle assessment at the farm scale. Eco-efficiency, which is defined as net farm income divided by global warming potential, is used as an integrated indicator for assessing the economic and environmental feasibilities. The results show that under the current direct payment level, the prolonged midseason drainage technique does not improve the eco-efficiency of Japanese rice farms because the practice of this technique in environmentally friendly rice production causes large economic disadvantages in exchange for small environmental advantages. The direct payment rates for agri-environmental measures should be determined based on the condition that environmentally friendly agricultural practices improve eco-efficiency compared with conventional agriculture.

    Animal welfare is typically assessed on farms by external observers making systematic observations of animals and/or the environment. External observers are costly, and efforts to minimize the time spent by external observers are giving rise to a delicate discussion of priorities of costs, validity...... and reliability. In this situation, it is worthwhile to consider the option of systems for assessing the animal welfare without having an external observer visiting the farm....

  10. Between Evasion and Activism: A Qualitative Inquiry into the Political Behavior of German and Swedish Long-Term Unemployed

    Jennifer Hobbins

    2015-01-01

    Full Text Available This comparative article aims to understand the patterns underlying the political behavior of young German and Swedish long-term unemployed individuals. Based on almost 40 qualitative interviews, the analysis follows a grounded theory approach and shows that “unemployment” is not an objective reality that imposes uniform living conditions. Social and political activities diverge considerably, even though our respondents experience similar pressures and sanctions by public opinion, political parties, public administrations, relatives and/or acquaintances. The consequences of unemployment depend on individual mind-sets, support networks and coping strategies. This study identifies informal networks of social relations as one main factor influencing unemployed young peoples’ political behavior. Three types of political involvement are shaped by the routines and norms reproduced within their web of social relations in everyday life: evasion, civic minimalism and reluctant activism. The similarities between the German and the Swedish respondents overshadowed the national differences

    The aims of this study were 1) to describe changes in self-assessed masticatory ability over a 14 year period (1975-89); and 2) to describe associations between self-assessed masticatory ability and age, dental state and some other background factors in a sample of the Swedish population in 1988/89. The Swedish National Central Bureau of Statistics investigates annually the living conditions of the Swedish population by means of interviews by trained persons. The data were analysed by means of stepwise logistic regression and calculation of adjusted relative risks. In the investigation in 1988/89, 12,901 people above 16 years of age participated and the response rate was 80%. In comparison between the investigations, the prevalence of reported impairment was lower in 1988/89 than in 1975 and 1980/81. Prevalence of reported impairment of chewing ability increased with ageing from 2% in young adults (16-34 years old) to 44% in older elderly (> 85 years old). In most age groups, edentulous people reported the highest prevalence, and dentate people the lowest. Relative risks for impaired masticatory ability, independent of age, gender and dental state, were higher for people in rural areas, with low income and living single, as well as for those with skeletal, gastrointestinal, psychiatric and tumour diseases. In the elderly, results from the logistic regression showed that some disability and psychosocial factors were also associated with masticatory ability. The results indicated that there was a group of elderly people who reported several functional and health problems including impaired masticatory ability.

    2011-12-01

    In 2003 the wide-ranging Swedish National Public Health Policy (SNPHP), with a focus on health determinants, was adopted by the Swedish parliament. In the context of multilevel governance, SNPHP implementation is dependent on self-governed municipalities and counties. The aim of the study is, from a municipal perspective, to investigate public-health policies in two municipalities. Content analysis of documents and interviews provided a foundation for an explorative case study. The SNPHP at national level is overriding but politically controversial. At local level, a health-determinants perspective was detectable in the policies implemented, but none regarding to health equality. At local level, the SNPHP is not regarded as implementable; rather, limited parts have, to varying degrees, been reconciled with local public-health goals, according to municipal needs and conditions. A success-promoting factor in the two municipalities was the presence of committed and knowledgeable actors/implementers. Also, the municipality with a more centrally controlled and stable party-political leadership succeeded better in implementing structural and intersectoral community-wide policies for coordinated local health promotion. The contents of national and local public-health policies differ, and municipalities that have implemented their own local health policies do not seem to regard the SNPHP as justifiable or adoptable. If the SNPHP overall aim regarding equal health is to be achieved homogeneously in Swedish municipalities, its contents and purpose need clearer management and negotiation, so that implementation of the national policy locally is understandable and motivated.

    In this final report describes and documents research that was conducted by the Ecological Engineering Research Program (EERP) at the University of the Pacific (Stockton, CA) under subcontract to Fiscalini Farms LP for work under the Assistance Agreement DE-EE0001895 'Measurement and Evaluation of a Dairy Anaerobic Digestion/Power Generation System' from the United States Department of Energy, National Energy Technology Laboratory. Fiscalini Farms is operating a 710 kW biomass-energy power plant that uses bio-methane, generated from plant biomass, cheese whey, and cattle manure via mesophilic anaerobic digestion, to produce electricity using an internal combustion engine. The primary objectives of the project were to document baseline conditions for the anaerobic digester and the combined heat and power (CHP) system used for the dairy-based biomass-energy production. The baseline condition of the plant was evaluated in the context of regulatory and economic constraints. In this final report, the operation of the plant between start-up in 2009 and operation in 2010 are documented and an interpretation of the technical data is provided. An economic analysis of the biomass energy system was previously completed (Appendix A) and the results from that study are discussed briefly in this report. Results from the start-up and first year of operation indicate that mesophilic anaerobic digestion of agricultural biomass, combined with an internal combustion engine, is a reliable source of alternative electrical production. A major advantage of biomass energy facilities located on dairy farms appears to be their inherent stability and ability to produce a consistent, 24 hour supply of electricity. However, technical analysis indicated that the Fiscalini Farms system was operating below capacity and that economic sustainability would be improved by increasing loading of feedstocks to the digester. Additional operational modifications, such as increased utilization of

    2014-01-01

    Full Text Available The aim of this paper was to compare two methods of farming, especially their effect on water soil erosion. The examined methods were (1 large-scale farming, where more than 50% of the land was leased, and (2 small-scale farming, where the land was almost exclusively privately owned. The research area was 8 cadastres in the district of Hodonín, South Moravia, Czech Republic. In these cadastres 48 land blocks representing both large-scale and small-scale farming (i.e. owners and tenants were chosen. The long-term average annual soil loss caused by water erosion (G was calculated using the erosion model USLE 2D and ArcGIS 10.1. The nonparametric Mann-Whitney test was used for the statistical evaluation of the data. The difference between the soil loss (G on land blocks farmed by small producers (owners and large producers (tenants was significant (p < 0.05. Differences between the values of the cropping-management factor (C were not statistically significant (p = 0.054. Based on the analysis of other variables in the USLE equation it can be stated that a continuous slope length, conditioned by the size of land blocks, played an important role in the amount of soil loss caused by water erosion. Above all, to protect the soil from erosion and maintain soil quality it is necessary to reduce the size of land blocks farmed by tenants and improve the crop rotation systems.

    The risk in agriculture sector is due to various factors like weather and market conditions, particularly the demand of the commodities. This uncertainty can result in variable returns (farm income) to the decisions that farmers make in a particular season. Diversification is a frequently used risk management strategy that involves participation in more than one activity. It has the added advantage of mitigating price risk as well as fluctuations in outputs. The main purpose of this paper was to determine the factors affecting crop diversification. For determining the effect of different factors on diversification a multiple regression model was used. The values of Entropy index computed for measuring horizontal diversification were taken as dependent variable and different factors affecting diversification were taken as independent variables. The results showed that the main factors affecting diversification were size of land holding, age of respondent, education level of respondent, farming experience of respondent, off farm income of respondent, distance of farm from main road, distance of farm from main market and farm machinery.

    2017-08-01

    Full Text Available The issue of assessment of absolute and comparative sustainability of major governing structures in agrarian and farming industries is among the most topical issues for researchers, farmers, investors, administrators, politicians, interests groups, and the public worldwide. Despite this issue, practically there are no assessments on the sustainability level of the major types of Bulgarian farming enterprises in the conditions of European Union Common Agricultural Policy implementation. This study applies a holistic framework and assesses the absolute and comparative sustainability of major governing structures in Bulgarian farming industry—unregistered holdings, sole traders, cooperatives, and companies of various types. In this paper, the method of the study is outlined, the inclusion of a novel “governance aspect” of sustainability is justified, and the overall characteristics of the surveyed farming enterprises are presented. Then, the integral, governance, economic, social, and environmental sustainability of the farming structures of different juridical types is assessed. Next, the structure of farming enterprises with different sustainability levels is analyzed. Finally, the conclusion from this study and the directions for further research and amelioration of sustainability assessments are presented.

    Svennerlind, Christer; Nilsson, Thomas; Kerekes, Nóra; Andiné, Peter; Lagerkvist, Margareta; Forsman, Anders; Anckarsäter, Henrik; Malmgren, Helge

    2010-01-01

    Historically, the Swedish criminal justice system conformed to other Western penal law systems, exempting severely mentally disordered offenders considered to be unaccountable. However, in 1965 Sweden enforced a radical penal law abolishing exceptions based on unaccountability. Mentally disordered offenders have since then been subjected to various forms of sanctions motivated by the offender's need for care and aimed at general prevention. Until 2008, a prison sentence was not allowed for offenders found to have committed a crime under the influence of a severe mental disorder, leaving forensic psychiatric care the most common sanction in this group. Such offenders are nevertheless held criminally responsible, liable for damages, and encumbered with a criminal record. In most cases, such offenders must not be discharged without the approval of an administrative court. Two essentially modern principles may be discerned behind the "Swedish model": first, an attempted abolishment of moral responsibility, omitting concepts such as guilt, accountability, atonement, and retribution, and, second, the integration of psychiatric care into the societal reaction and control systems. The model has been much criticized, and several governmental committees have suggested a re-introduction of a system involving the concept of accountability. This review describes the Swedish special criminal justice provisions on mentally disordered offenders including the legislative changes in 1965 along with current proposals to return to a pre-1965 system, presents current Swedish forensic psychiatric practice and research, and discusses some of the ethical, political, and metaphysical presumptions that underlie the current system.

  20. The circumplex structure of affect: a Swedish version.

    Science.gov (United States)

    Knez, I; Hygge, S

    2001-12-01

    The taxonomy of a circumplex model has been widely applied in the emotion domain and especially by researchers advocating a systematic arrangement of conscious emotional experience (see Fabrigar, Visser & Browne, 1997; Feldman Barett & Russell, 1999 for recent reviews). To rule out some of the lexical problems in the naming of affective states in the circumplex space, Larsen and Diener (1992) suggested a labeling system with forty-eight English adjectives representing eight affective states. The objective of the present study was to examine how well Swedish adjectives map onto a dimensional model of this kind, in doing so, to compose a Swedish measure for self-reported affect. The forty-eight Swedish adjectives translated from Larsen and Diener (1992) failed to capture a pure circumplex structure. However, when approximately two thirds of these adjectives were reanalyzed, a reasonable consistency with the circumplex model was reached. This suggested a composite Swedish measure for self-rated affect, with up to four adjectives representing each of the eight affective states in the circumplex space.

    The increasing size of wind turbines, with rotors already spanning more than 150 m diameter and hub heights above 100 m, requires proper modeling of the atmospheric boundary layer (ABL) from the surface to the free atmosphere. Furthermore, large wind farm arrays create their own boundary layer structure with unique physics. This poses significant challenges to traditional wind engineering models that rely on surface-layer theories and engineering wind farm models to simulate the flow in and around wind farms. However, adopting an ABL approach offers the opportunity to better integrate wind farm design tools and meteorological models. The challenge is how to build the bridge between atmospheric and wind engineering model communities and how to establish a comprehensive evaluation process that identifies relevant physical phenomena for wind energy applications with modeling and experimental requirements. A framework for model verification, validation, and uncertainty quantification is established to guide this process by a systematic evaluation of the modeling system at increasing levels of complexity. In terms of atmospheric physics, 'building the bridge' means developing models for the so-called 'terra incognita,' a term used to designate the turbulent scales that transition from mesoscale to microscale. This range of scales within atmospheric research deals with the transition from parameterized to resolved turbulence and the improvement of surface boundary-layer parameterizations. The coupling of meteorological and wind engineering flow models and the definition of a formal model evaluation methodology, is a strong area of research for the next generation of wind conditions assessment and wind farm and wind turbine design tools. Some fundamental challenges are identified in order to guide future research in this area.

    Pig farmers are strongly encouraged to reduce their antimicrobial usage because of the rising threat from antimicrobial resistance. However, such efforts should not compromise the herd health status and performance. This study aimed to describe the profile of so-called 'top-farms' that managed to combine both high technical performance and low antimicrobial usage. A cross-sectional study was conducted among 227 farrow-to-finish farms in Belgium, France, Germany and Sweden. Among them, 44 farms were allocated to the top-farms group and were compared with the 'regular' farms group in terms of farm characteristics, biosecurity and health status. Top-farms had fewer gastrointestinal symptoms in suckling pigs and fewer respiratory symptoms in fatteners, which could partly explain their reduced need for antimicrobials and higher performance. They also had higher biosecurity and were located in sparsely populated pig areas. However, 14 farms of the top-farms group were located in densely populated pig areas, but still managed to have low usage and high technical performance; they had higher internal biosecurity and more extensive vaccination against respiratory pathogens. These results illustrate that it is possible to control infectious diseases using other approaches than high antimicrobial usage, even in farms with challenging environmental and health conditions. © British Veterinary Association (unless otherwise stated in the text of the article) 2017.

    2005-01-01

    The aim of the LHCb on-line farm Monitor System is to keep under control all the working indicators which are relevant for the farm operation, and to set the appropriate alarms whenever an error or a critical condition comes up. Since the most stressing tasks of the farm are the data transfer and processing, relevant indicators includes the CPU and the memory load of the system, the network interface and the TCP/IP stack parameters, the rates of the interrupts raised by the network interface card and the detailed status of the running processes. The monitoring of computers’ physical conditions (temperatures, fan speeds and motherboard voltages) are the subject of a separate technical note, since they are accessed in a different way, by using the IPMI protocol.

  7. Swedish snus and the GothiaTek® standard

    Directory of Open Access Journals (Sweden)

    Ringberger Tommy

    2011-05-01

    Full Text Available Abstract Some smokeless tobacco products, such as Swedish snus, are today considered to be associated with substantially fewer health hazards than cigarettes. This risk differential has contributed to the scientific debate about the possibilities of harm reduction within the tobacco area. Although current manufacturing methods for snus build on those that were introduced more than a century ago, the low levels of unwanted substances in modern Swedish snus are largely due to improvements in production techniques and selection of raw materials in combination with several programs for quality assurance and quality control. These measures have been successively introduced during the past 30-40 years. In the late 1990s they formed the basis for a voluntary quality standard for Swedish snus named GothiaTek®. In recent years the standard has been accepted by the members of the trade organization European Smokeless Tobacco Council (ESTOC so it has now evolved into an industrial standard for all smokeless tobacco products in Europe. The initial impetus for the mentioned changes of the production was quality problems related to microbial activity and formation of ammonia and nitrite in the finished products. Other contributing factors were that snus came under the jurisdiction of the Swedish Food Act in 1971, and concerns that emerged in the 1960s and 1970s about health effects of tobacco, and the significance of agrochemical residues and other potential toxicants in food stuffs. This paper summarizes the historical development of the manufacture of Swedish snus, describes the chemical composition of modern snus, and gives the background and rationale for the GothiaTek® standard, including the selection of constituents for which the standard sets limits. The paper also discusses the potential future of this voluntary standard in relation to current discussions about tobacco harm reduction and regulatory science in tobacco control.

    Full Text Available This papertests thehypothesis that off-farm income relaxes the liquidityconstraints of farm households usingsurvey data derived from 734 householdsfrom eight villages, drawn from the three agro-climatic zones of northernEthiopia.The results of the econometric models show that off-farm incomepositively affects agricultural input expenditure but negatively affects livestockinvestment. This may be explained by the higher per capita land holdings ofhouseholds who invest in improved agricultural inputs compared to those whoinvest in livestock. Our results show the complementarities between off-farmactivities and productivity enhancing investment for agricultural inputs. However,off-farm activities may be competing for labor resources for landless and nearlandless households (those who invest in livestock.

    Full Text Available The objective of this work was to investigate the influence of housing conditions, number of farrowing and number of pigs in litter on weight loss in sows during lactation. The experiment included 60 sows, half breed developed by cross breeding of Big Yorkshire and Swedish Landrace in lactation. Body weight of the sows (kg was determined 2nd, 7th, 14th, 21st and 28th day after farrowing. On the basis of the obtained values, there was calculated the difference in body weight between two consecutive investigation periods. The sows were divided into two groups and held in different housing conditions: 30 of them were held in extensive, and other 30 sows in intensive way of farming. In regard to number of farrowing, the sows were divided into three groups: sows with one or two farrowing (group P1, n=20, with three or four farrowing (group P2, n=20, and sows that farrowed five or more times (P3,n=20. In regard to number of pigs in litter, the sows were divided into two groups: the first (Group I, n=30 with sows that had up to eight pigs, and the second (Group II, n=30 with sows that had nine or more pigs in litter. The obtained results showed that in all perids of the investigation during lactation, body weight in sows held in extensive farming conditions was statistically significantly higher compared to those from intensive farming conditions. On the other hand, the loss of body weight during lactation was significantly higher in sows from extensive in regard to intensive farming conditions in the first two weeks of lactation. The sows with bigger number of farrowing had greater body weight, compared to those with smaller number of farrowing. There was no statistically significant difference in body weight loss during lactation, between sows with different number of farrowing, but considering that the sows with less farrowings had significantly lower body weight, they consequently lost more weight in percentage. The sows with greater number of pigs

  11. Stakeholder Involvement in Swedish Nuclear Waste Management

    investigations may change. A different understanding of what should be subject to stakeholder involvement is now on the table, but how exactly this will influence the process is still too early to say. The group most visible so far, the Swedish NGO Office for Nuclear Waste Review (MKG), has published, however, a thorough review of SKB's RandD programme from 2004. In this it is obvious that the Group wants to focus on a more strict assessment of a proposed final repository in relation to the requirements stated in the Environmental Code, that the suitability of a site should be determined by its ability to protect human health and the environment, which places substantial demands upon the site chosen. Moreover, according the Code the best available technology should be used and alternative technology presented. According to MKG, SKB are not fulfilling these requirements in respect of the Environmental Code. The KBS method as well as the two sites in Oskarshamn and Oesthammar are not chosen in relation to these requirements (MKG 2005). MKG, therefore, seems unwilling to proceed on the assumption that a final repository should be sited in either Oesthammar or Oskarshamn, without detailed comparisons with other sites being carried out. In this paper we have tried to show the changing patterns of stakeholder involvement, and also that the current pattern, often mentioned as stable, is not naturally given. Many uncertainties could be listed, but what we know for sure is that the nature of stakeholder involvement at any moment in time always remains contingent and fluid. Who the major and minor stakeholders are; which opportunities they have to act, and on what issues are continually shifting matters. While things can appear to be proceeding in a relatively orderly step-by-step fashion, the reality of stakeholder involvement is that things are continually on the verge of turning out otherwise

    Studies of antibiotic prescribing related to diagnosis comparing prescribers trained abroad with those trained in Sweden are lacking. To determine whether general practices (GPs) and GP residents trained abroad had different prescribing patterns for antibiotics for common infections than those trained in Sweden using retrospective data from electronic patient records from primary health care in Kalmar County, Sweden. Consultations with an infection diagnosis, both with and without the prescription of antibiotics to 67 GPs and residents trained in Western Europe outside Sweden and other countries, were compared with a matched control group trained in Sweden. For 1 year, 44101 consultations of patients with an infection diagnosis and 16276 prescriptions of antibiotics were registered. Foreign-trained physicians had 20% more visits compared with physicians trained in Sweden. The prescription of antibiotics per visit and physician in the respective groups, and independent of diagnosis, did not significantly differ between groups, when scaled down from number of consultations to number of prescribing physicians. There were minor and non-significant differences in antibiotic prescribing comparing GPs and residents trained abroad and in Sweden, most likely the result of an adaptation to Swedish conditions. Nevertheless, no group prescribed antibiotics in accordance to national guidelines. The results suggest that interventions are needed to reduce irrational antibiotic prescribing patterns, targeting all physicians working in Swedish primary health care. © The Author 2015.

    Grahn, P.H.; Hedin, G.

    2005-01-01

    In Sweden, the duties and responsibilities involved in handling radioactive waste were defined in the seventies. The 1976 Stipulation Law provides for the originator of the waste to be fully responsible for te waste arising in the course of plant operation. SKB, Swedish Nuclear Fuel and Waste Management Co., was founded by the Swedish operators of nuclear power plants in 1972 to take care of nuclear power plant waste management and radioactive waste treatment. In the eighties, the Finance Act was adopted which provides for the establishment of a fund to finance complete disposal of nuclear power plant waste, including radioactive waste and spent fuel. Over the past few years, there have been various developments in nuclear power plant waste management: - Reprocessing of spent fuel is no longer part of the waste management strategy. The fuel elements are stored in a central interim store, CLAB, which has been in operation since 1985 and now holds approx. 4 000 t of fuel elements. - A transport system for radioactive waste and spent fuel has been in operation successfully since 1985. - A repository for low- and medium-level waste has been in operation since 1985. - Work has been underway for the past twenty years in research, development, and construction of an underground repository for spent fuel. Development has now reached a stage which will allow a decision to be taken within the next five or ten years about the sites of the conditioning plant and the repository. (orig.)

  2. Biodiversity and sectoral responsibility in the development of Swedish Forestry Policy, 1988-1993.

    Science.gov (United States)

    Bush, Terrence

    2010-01-01

    In 1993 the Swedish parliament deregulated national forestry policy and established an environmental goal in parallel with the previous, long-standing goal of high wood production. This paper shows how the change occurred in the context of major changes in Swedish environmental policy during the late 1980s and early 1990s. Within a short time, new environmental legislation and the introduction of legal protection for small forest and agricultural habitats of high ecological value reoriented national forestry policy, away from an overriding focus on wood production to an increased awareness of nature conservation and biodiversity preservation. Reflecting a major compromise with the state, forest owners have gained greater freedom to manage their land, but must also improve environmental conditions while achieving high wood production, a policy known as 'freedom under responsibility'. The paper explains how both the parliament and industry supported increased nature conservation and biodiversity to maintain forest health and support the forestry industry, by favouring responsible resource use and not simply protection from human influence.

    Nuclear power companies in Sweden jointly established the Swedish Nuclear Fuel and Waste Management Company (SKB) in the 1970s. SKB's assignment is to manage and dispose of all radioactive waste from Swedish nuclear power plants in such a way as to secure maximum safety for human beings and the environment. Since 1992 a stepwise process has been under way, aiming at finding a site for a final repository for spent nuclear fuel. This process was based on our view that a successful work requires that the safety of the site finally selected is met and that the municipality is in favour of the siting. SKB's record of communication related activities includes a wide variety of experiences, and we have learned from all of them. Over time we have identified a number of basic conditions, which are fundamental for a stable and successful siting process. - The siting process shall be transparent and based on voluntary participation. - It's important to maintain a constant dialogue and to express it in comprehensible terms. - A clear division of responsibilities between stakeholders is a key question. - Give the process the time that is needed - try to avoid being in too much of a hurry. - A step-wise and adaptive approach to the implementation of the disposal system. - Despite all non-technical aspects of communication, the continued good performances of operating facilities and of R and D work to guarantee top-quality technical systems are a must.

    Darier disease is an autosomal dominant skin disorder caused by mutations in the ATP2A2 gene. Anecdotal reports suggest a relationship between Darier disease and intellectual disabilities, but these reports are based on small clinical samples and limited by absence of control populations. To examine the risk of intellectual disability and subclinical impairments in cognitive ability in Darier disease. We conducted a matched cohort study based on Swedish Population-, Patient- and Conscript Registers. The risk of being diagnosed with intellectual disability was estimated in 770 individuals with Darier disease, compared with matched comparison individuals without Darier disease. Associations were examined with risk ratios from conditional logistic regressions. In addition, we analysed test-based cognitive ability data (i.e. IQ data) from the Swedish conscript examination, for a subset of patients without diagnosed intellectual disability. Individuals with Darier disease had a sixfold increased risk of being diagnosed with intellectual disability (risk ratio 6.2, 95% confidence interval 3.1-12.4). For conscripted individuals with Darier disease but no diagnosed intellectual disability, mean cognitive ability scores were about half a standard deviation lower than for comparison subjects. Darier disease is associated with intellectual disability and subclinical impairments in cognitive ability. The Darier-causing mutations merit further attention in molecular genetic research on intellectual disability and cognitive ability. © 2015 British Association of Dermatologists.

  5. [National and regional prioritisation in Swedish health care: experiences from cardiology].

    Science.gov (United States)

    Carlsson, Jörg

    2012-01-01

    Prioritisation of medical services in Sweden takes place on two different levels. On the national level, the Swedish priority guidelines ascribe priority values ranging from 1 (high priority) to 10 (low priority) to measures (in terms of condition-treatment pairs) of prevention, diagnosis, treatment and rehabilitation of cardiovascular diseases. In addition, this list contains interventions that should be avoided and those that should only be provided as part of clinical research projects. The government then commissions a multi-professional team under the supervision of the National Board of Health and Welfare "Socialstyelsen" with the development of corresponding guidelines. In addition to the scientific evidence, the priority lists incorporate ethical and economical aspects and are based on the so-called ethics platform consisting of human dignity, needs, solidarity and cost-effectiveness. At the other level of prioritisation there are regional projects aiming at the in- and exclusion of medical measures. The Swedish prioritisation process will be described using the example of priority lists in cardiology. (As supplied by publisher). Copyright © 2012. Published by Elsevier GmbH.

    Full Text Available In the article diversifying the level of financial liquidity of farm in UE was presented. The research showed that a higher financial liquidity than non-agricultural sectors characterized farming. This state is a result of relatively smaller participation of short-term capital in total capital. In the EU countries the highest financial liquidity is met in farms of Belgium, Spain and Slovenia, however lowest in farms of Great Britain, the Czech Republic and Netherlands. The financial liquidity is also strongly diversified according to the economic size, the type of farms and conditions of agricultural production.

    Asthma is often associated with other diseases. To identify and manage comorbidities is important, as these conditions may increase the disease burden. To describe the prevalence of comorbidities, disease burden and mortality across age groups in a large Swedish primary care real-life asthma population. Observational cohort study of asthma patients, all ages, identified from electronic medical records by ICD-10-CM code, data from 36 primary care centers. Data were linked to national mandatory Swedish health registers. Comorbidities were identified by ICD-10-CM codes and collected from electronic medical records and the National Patient Registers, mortality data from the Cause of Death Register. Exacerbations were defined as hospitalizations due to asthma, and/or emergency visits at hospital and/or prescription claims of oral steroids. In total 33,468 patients (58% women) were included. The most prevalent comorbidities were acute upper respiratory tract infection (53%), rhinitis (25%), acute lower respiratory tract infection (25%), hypertension (21%), anxiety and depression (20%). The comorbidities associated with highest risk for an exacerbation were COPD OR 1.98 (95%CI: 1.80-2.19), nasal polyps OR 1.75 (95%CI: 1.49-2.05) and rhinitis OR 1.52 (95%CI: 1.41-1.63). All-cause mortality was similar to the Swedish population, 1011 deaths per 100,000 person/year compared with 1058 deaths (standardized risk = 0.99 [95%CI:0.95-1.04]). The pulmonary related death rate was greater in the study population versus the Swedish population (122 versus 72 per 100,000person/year). Comorbid disease was frequent in this large real-life asthma population with an impact on exacerbations. To identify and treat comorbidities with impact on asthma outcomes are essential to improve asthma care. Copyright © 2018 The Authors. Published by Elsevier Ltd.. All rights reserved.

    Airicole, GE Wind Energy and SEAS/Energi E2 have initiated this project in order to achieve a better understanding on how offshore based wind farms effect the underwater noise. The main reason is to gain knowledge on how marine wildlife could be effected by this kind of installation. The measurements were performed at Utgrunden wind farm that is situated at the reef Utgrunden on the Swedish southeast coast. The farm consists of seven 1,5 MW turbines. Three hydrophones registered the underwater sound and four accelerometers the tower vibrations. The measurement campaign was conducted during a period from November 2002 to February 2003. The objectives with this project is to answer the following issues and its results are: 1. What is the character of sound from a single power station? - The turbines radiate sound mainly at a few dominating frequencies from 30 Hz up to 800 Hz. At frequencies below 3 Hz no contribution from the turbines can be detected due to the high background level from the waves and the low tower vibration level. 2. What are the sound generating mechanisms in the turbine? - Gearbox mesh frequency vibrations that are transmitted via the tower structure and radiated out to the water mainly generate the sound. Airborne blade sound is effectively dampened in the transition from air to water. 3. How does the sound attenuate with increasing distance at different frequencies? - The average attenuation per doubled distance for frequencies between 31 Hz and 722 Hz is approximately 4 dB in the measured positions. No clear frequency dependence could be found. 4. How does the sound pressure level vary with increasing wind speed? - With increasing wind speed, the sound pressure level increases and the dominating frequencies move upward due to increasing turbine rotational speed. 5. How does sound from different power stations interfere with each other and influence the over all sound image? - No clear tendencies of interference could be observed in this study

    A wind farm optimization framework is presented in detail and demonstrated on two test cases: 1) Middelgrunden and 2) Stags Holt/Coldham. A detailed flow model describing the instationary flow within a wind farm is used together with an aeroelastic model to determine production and fatigue loading of wind farm wind turbines. Based on generic load cases, the wind farm production and fatigue evaluations are subsequently condensed in a large pre-calculated database for rapid calculation of lifetime equivalent loads and energy production in the optimization loop. The objective function defining the optimization problem includes elements as energy production, turbine degradation, operation and maintenance costs, electrical grid costs and foundation costs. The objective function is optimized using a dedicated multi fidelity approach with the locations of individual turbines in the wind farm spanning the design space. The results are over all satisfying and are giving some interesting insights on the pros and cons of the design choices. They show in particular that the inclusion of the fatigue loads costs give rise to some additional details in comparison with pure power based optimization. The Middelgrunden test case resulted in an improvement of the financial balance of 2.1 M Euro originating from a very large increase in the energy production value of 9.3 M Euro mainly counterbalanced by increased electrical grid costs. The Stags Holt/Coldham test case resulted in an improvement of the financial balance of 3.1 M Euro. (Author)

    The amount of installed wind power varies significantly across municipalities although the financial support for wind power production and the technology available is identical in all Swedish municipalities. This study analyses how local differences between municipalities, such as local wind prerequisites and socioeconomic conditions, might explain the establishment of wind power. The analysis is carried out for a cross section of Swedish municipalities. The time periods before and after 2006 are analyzed separately; and results reveal that the factors affecting wind power establishments are different between the two periods. In the later time period we found a statistically significant positive relationship between good wind resources and the presence of wind power as well as with the amount of wind energy installed. This result is consistent with the idea that the first wind power investments in Sweden were highly affected by individual wind energy enthusiasts, while in the more recent large-scale investments market-based judgments about future profitability may have become increasingly important. In addition, previous experience seems to be a factor that in itself facilitates additional future wind power establishments, thereby pointing to the role of accumulated institutional capacity. - Highlights: ► Local differences in installed wind power capacity in Sweden is analysed. ► The amount of installed wind power capacity varies significantly in time and space. ► Results reveal different determinants of installed capacity before/after 2006. ► Good wind resources have become increasingly important over time. ► Previous experience of wind power has a positive impact on installed capacity

    Improved shrimp farming affects the groundwater quality conditions. Assessment of shrimp farming impact on groundwater quality conventionally has less accuracy. This paper presents the implementation of Analytical Hierarchy Process (AHP) method for assessing shrimp farming impact on groundwater quality. The data used is the impact data of shrimp farming in one of the regions in Indonesia from 2006-2016. Criteria used in this study were 8 criteria and divided into 49 sub-criteria. The weighting by AHP performed to determine the importance level of criteria and sub-criteria. Final priority class of shrimp farming impact were obtained from the calculation of criteria's and sub-criteria's weights. The validation was done by comparing priority class of shrimp farming impact and water quality conditions. The result show that 50% of the total area was moderate priority class, 37% was low priority class and 13% was high priority class. From the validation result impact assessment for shrimp farming has been high accuracy to the groundwater quality conditions. This study shows that assessment based on AHP has a higher accuracy to shrimp farming impact and can be used as the basic fisheries planning to deal with impacts that have been generated.

    Full Text Available Farm records are mostly manually kept on paper notebooks and folders where similar records are organized in one folder or spread sheet. These records are usually kept for many years therefore they becomes bulky and less organized. Consequently, it becomes difficult to search, update and tedious and time consuming to manage these records. This study was carried-out to overcome these problems associated with manual farm records keeping by developing user-friendly, easily accessible, reliable and secured software. The software was limited records keeping in crop production, livestock production, poultry production, employees, income and expenditure. The system was implemented using Java Server Faces (JSF for designing Graphical User Interface (GUI, Enterprises Java Beans (EJB for logic tier and MySQL database for storing farm records.
