    Full Text Available Economic weights for milk carrier (water plus lactose, fat and protein yields, calving interval, age at first service, interval between the first service and conception of heifers and length of productive life of Estonian Holsteins were estimated under assumed milk production quota and for non-quota conditions. A bio-economic model of an integrated production system of a closed herd was used. Economic values of milk carrier yield and length of productive life differed between quota and non-quota conditions, but there were only minor differences between those marketing systems in economic values for functional traits. The standardised economic values of the most important traits varied in magnitude between18 to 81% of the economic value for milk yield. Discounting had a substantial impact on the economic value of length of productive life. When defining the breeding objective for Estonian Holstein, the interval between the first service and conception of heifers, and the length of productive life should be included in the breeding goal along with the traits with the highest economic value, milk, fat and protein yield. In the optimum breeding objective, relative weights of production vs. functional traits were 79 and 21%, respectively.;

    Full Text Available Abstract Background Objectives of the study were to document the impact of some management factors on the occurrence of clinical mastitis in primiparous dairy cows and to identify common udder pathogens of clinical mastitis in freshly calved heifers and multiparous cows on the day of calving. Methods A one-year study was conducted during 2004 and 2005 in 11 selected Estonian dairy herds. Data consisted of 68 heifers with clinical mastitis and 995 heifers without clinical mastitis on the day of calving. Multivariable logistic regression with a random herd effect was used to investigate any association between housing system or the time interval from movement of heifers to the calving facility and day of calving on occurrence of clinical mastitis. Milk samples for bacteriological analysis were collected from affected heifers and multiparous cows on the day of calving Results Clinical mastitis occurrence in the study population of freshly calved heifers equalled 6.1 %. Housing system was not a significant risk factor for clinical mastitis of freshly calved heifers. Moving heifers to the cowbarn less than two weeks before calving in tiestall farms increased risk (OR = 5.9 p = 0.001 for clinical mastitis at parturition. The most frequently isolated udder pathogens among heifers were Escherichia coli (22.1%, Streptococcus uberis (19.1% and coagulase-negative staphylococci (8.8%. In comparison, the main pathogen in multiparous cows with clinical mastitis at parturition was Staphylococcus aureus (11.2%. Conclusion Moving heifers to the calving facilities too late in tiestall farms increased risk for clinical mastitis at parturition. The isolated udder pathogens did not differ significantly in tiestall farms compared to freestall farms in heifers, but differences were found between heifers and multiparous cows at parturition.

    The objective of this research was to define and analyze drops in reticulo-rumen temperature (Trr) as an indicator of calving time in Holstein females. Data were collected from 111 primiparous and 150 parous Holstein females between November 2012 and March 2013. Between -15 and -5 d relative to anticipated calving date, each female received an orally administered temperature sensing reticulo-rumen bolus that collected temperatures hourly. Daily mean Trr was calculated from d -5 to 0 relative to using all Trr values (A-Trr) or only Trr values ≥37.7°C (W-Trr) not altered by water intake. To identify a Trr drop, 2 methodologies for computing the baseline temperature were used. Generalized linear models (GLM) were used to estimate the probability of calving within the next 12 or 24 h for primiparous, parous, and all females, based on the size of the Trr drop. For all GLM, a large drop in Trr corresponded with a large estimated probability of calving. The predictive power of the GLM was assessed using receiver-operating characteristic (ROC) curves. The ROC curve analyses showed that all models, regardless of methodology in calculation of the baseline or tested category (primiparous or parous), were able to predict calving; however, area under the ROC curve values, an indication of prediction quality, were greater for methods predicting calving within 24 h. Further comparisons between GLM for primiparous and parous, and using baseline 1 and 2, provide insight on the differences in predictive performance. Based on the GLM, Trr drops of 0.2, 0.3, and 0.4°C were identified as useful indicators of parturition and further analyzed using sensitivity, specificity, and diagnostic odds ratios. Based on sensitivity, specificity, and diagnostic odds ratios, the best indicator of calving was an average Trr drop ≥0.2°C, regardless of methodology used to compute the baseline or category of animal evaluated.

    The objective of this observational study was to determine the association of exposure to selected bedding types with incidence of subclinical (SM) and clinical mastitis (CM) in primiparous Holstein dairy cows housed in identical pens at a single facility. At parturition, primiparous cows were randomly assigned to pens containing freestalls with 1 of 4 bedding materials: (1) deep-bedded new sand (NES, n=27 cows), (2) deep-bedded recycled sand (RS, n=25 cows), (3) deep-bedded manure solids (DBMS, n=31 cows), and (4) shallow-bedded manure solids over foam-core mattresses (SBMS, n=26 cows). For 12mo, somatic cell counts of quarter milk samples were determined every 28d and duplicate quarter milk samples were collected for microbiological analysis from all quarters with SM (defined as somatic cell count >200,000 cells/mL). During this period, duplicate quarter milk samples were also collected for microbial analysis from all cases of CM. For an additional 16mo, cases of CM were recorded; however, no samples were collected. Quarter days at risk (62,980) were distributed among bedding types and most quarters were enrolled for >150d. Of 135 cases of SM, 63% resulted in nonsignificant growth and 87% of recovered pathogens (n=33) were identified as coagulase-negative staphylococci. The distribution of etiologies of pathogens recovered from cases of SM was associated with bedding type. Coagulase-negative staphylococci were recovered from 12, 38, 11, and 46% of quarters with SM from cows in pens containing NES, RS, DBMS, and SBMS, respectively. A result of nonsignificant growth was obtained for 81, 59, 89, and 46% of quarters with SM from cows in pens containing NES, RS, DBMS, and SBMS, respectively. Quarters of primiparous cows bedded with NES tended to have greater survival time to incidence of CM than quarters of primiparous cows bedded with RS or DBMS.

    Full Text Available Abstract Background Insulin secretion and tissue sensitivity to insulin is considered to be one of the factors controlling lipid metabolism post partum. The objective of this study was to compare glucose-induced blood insulin and metabolite responses in Estonian Holstein (EH, n = 14 and Estonian Red (ER, n = 14 cows. Methods The study was carried out using the glucose tolerance test (GTT performed at 31 ± 1.9 days post partum during negative energy balance.

    Resumption of luteal activity postpartum and fertility were investigated in an Estonian Holstein high milk production and good fertility dairy herd. Body condition was scored after every 10 days in 54 multiparous dairy cows (71 lactations) calving inside from December to March during 4-year period. Blood samples were taken 1-14 days before calving and 1-14, 28-42 and 63-77 days after calving: analytes estimated were serum aspartate aminotransferase (AST), glucose, ketone bodies, total cholesterol, non-esterified fatty acids and triglycerides. The general linear mixed model was used to compare the data for cows with different characteristics in luteal activity postpartum based on their milk progesterone profiles. Forty-five per cent of cases had abnormal profiles; delayed resumption of ovarian cyclicity postpartum (DC) was the most prevalent abnormality. There was no difference in body condition scores between the groups. The DC and prolonged luteal phase groups had higher serum AST activity (p fertility.

    Feed efficiency has the potential to be improved both through feeding, management, and breeding. Including feed efficiency in a selection index is limited by the fact that dry matter intake (DMI) recording is only feasible under research facilities, resulting in small data sets and, consequently, uncertain genetic parameter estimates. As a result, the need to record DMI indicator traits on a larger scale exists. Rumination time (RT), which is already recorded in commercial dairy herds by a sensor-based system, has been suggested as a potential DMI indicator. However, RT can only be a DMI indicator if it is heritable, correlates with DMI, and if the genetic parameters of RT in commercial herd settings are similar to those in research facilities. Therefore, the objective of our study was to estimate genetic parameters for RT and the related traits of DMI in primiparous Holstein cows, and to compare genetic parameters of rumination data between a research herd and 72 commercial herds. The estimated heritability values were all moderate for DMI (0.32-0.49), residual feed intake (0.23-0.36), energy-corrected milk (ECM) yield (0.49-0.70), and RT (0.14-0.44) found in the research herd. The estimated heritability values for ECM were lower for the commercial herds (0.08-0.35) than that for the research herd. The estimated heritability values for RT were similar for the 2 herd types (0.28-0.32). For the research herd, we found negative individual level correlations between RT and DMI (-0.24 to -0.09) and between RT and RFI (-0.34 to -0.03), and we found both positive and negative correlations between RT and ECM (-0.08 to 0.09). For the commercial herds, genetic correlations between RT and ECM were both positive and negative (-0.27 to 0.10). In conclusion, RT was not found to be a suitable indicator trait for feed intake and only a weak indicator of feed efficiency. Copyright © 2017 American Dairy Science Association.

    The objective was to compare the relationships between luteal activity and fertility, and relate these parameters to metabolic indices and body condition changes in multiparous Estonian Holstein cows on two commercial dairy farms under different management and levels of production and nutrition (higher, H, n=54 (71 lactations) and lower, L, n=39 (39 lactations)). For statistical analysis cows were categorized according to their milk progesterone (P4) profiles as follows: normal ovarian function; delayed start of cyclicity (DC) (interval from calving to first luteal response (P45 ng/ml up to and more than 50 d respectively, followed by regular cyclicity); cessation of luteal activity (prolonged interluteal interval, P4bodies, non-esterified fatty acids, total cholesterol) and aspartate aminotransferase, body condition scores (BCS) and fertility parameters between the two farms, and also fertility parameters between the farms within P4 categories. Differences in milk fat/protein ratio, ketone body levels and BCS indicated a deeper negative energy balance (NEB) during the first month after calving on farm L. On both farms nearly 50% of the recently calved dairy cows suffered from ovarian dysfunction during the post-partum period. Delayed start of cyclicity was the most prevalent abnormal P4 profile, 25% and 28% on farms H and L, respectively. Prolonged luteal activity accounted for one-third of atypical ovarian patterns on farm H, and cessation of luteal activity on farm L. On farm L, DC cows had lower BCS values from day 10 to day 90 after calving compared with normal cows (Pcows lost more BCS (1.2 units) during the 40 d after calving than normal resumption cows (0.75 units; P<0.05). On farm H with moderate NEB the delayed start of ovulation post partum did not impair subsequent reproductive performance.

    The aim of this study was to evaluate the glucogenic property of glycerol supplementation in the dairy cow’s diet. Sixty primiparous cows (control, n=30, and glycerol supplemented, n=30) were used to measure milk yield and components, blood hormone and metabolite profiles, and body condition score. Feed intake and apparent total-tract digestibility were also measured using 10 primiparous cows (control, n=5, and glycerol supplemented, n=5). Dry glycerol was top dressed at 250 g/day/cow from parturition to 21 days postpartum. Average feed intake, milk yield and components were not affected by glycerol supplementation. Apparent total–tract digestibility of organic matter and neutral detergent fibre were not influenced by dry glycerol supplementation, but lipid digestibility was greater (p=0.01) in cows fed glycerol. The serum concentration of glucose and insulin tended to be higher in dry glycerol-supplemented cows (p=0.1; p=0.06, respectively). While, serum concentrations of nonesterified fatty acids and β-hydroxybutyrate were not affected. Supplemented cows had lower body condition loss during weeks 1 to 5 after calving (p=0.09). The glucogenic effect of glycerol did not affect milk yield during the first 3 weeks of lactation. However, daily milk yield during the 13 weeks recording period was higher in the glycerol-supplemented cows (28.5 vs. 30.3 kg, p<0.001). Percentages of cows cycling at the planned breeding date was greater (p=0.01) for cows fed dry glycerol. The results demonstrated that feeding dry glycerol as a glucogenic supply could be useful in saving body reserves and improving energy balance of primiparous Holstein dairy cows during the early postpartum period.

    This study examined the effects of dry glycerol supplementation on follicular growth, post-partum interval to first ovulation, concentration of serum metabolites and hormones related to fertility, body condition score (BCS) and body weight (BW) in primiparous Holstein dairy cows. Sixty primiparous Holstein dairy cows were randomly assigned to two groups (control: n = 30 and glycerol supplemented: n = 30). Dry glycerol (250 g/day/cow) was fed as a top dressing to the common lactating total mixed ration (TMR) from parturition to 21 days post-partum. Ovaries were examined four times using ultrasonography on days 13, 19, 25 and 36 post-partum to determine ovarian follicular growth. Concentration of serum metabolites and hormones was determined weekly. Body condition score was evaluated weekly from weeks 1 to 5 after parturition, and BWs were recorded three times on days 1, 11 and 21 during the experimental period. The cows fed dry glycerol had more large follicles (p cows. Days to the first ovulation (p = 0.06), days to first oestrus (p = 0.05), services per conception (p = 0.06) and days open (p = 0.004) were positively affected by dry glycerol supplementation. Serum concentration of glucose and insulin was higher in dry glycerol-supplemented cows (p = 0.1; p = 0.06, respectively). Feeding glycerol had no effect on mean serum concentrations of β-hydroxybutyrate, non-esterified fatty acids and IGF-1 during the experimental period. However, significant differences were observed at concentration of BHBA and IGF-1 (p = 0.02 and p = 0.04, respectively) between two groups on day 21 after calving. The cows in the glycerol-fed group had higher serum progesterone concentrations on days 33 (p = 0.007) and 36 (p = 0.004) after calving. Supplemented cows had lower body condition loss during weeks 1-5 after calving compared with the control cows (0.34 vs 0.41 BCS). In week 13 post-partum, the proportion of cycling cows was 83.3 and 69.9% for those which

In may five energy forest plantations (altogether 2 ha) were established in Estonia with Swedish selected clones of Salix viminalis and Salix dasyclados. The research within this project is carried out within three main directions. The studies of basic ecophysiological processes and radiation regime of willow canopy will be carried out in Toravere. The production ecology studies, comparison of the productivity of multiple clones on different soil types is based on the plantations as vegetation filter for wastewater purification is studied on the basis of plantations in Vaeike-Maarja and Valga (author)

    Estonia is situated on the eastern coast of the Baltic Sea. This is a region with intensive cyclonic activity and therefore with a relatively high mean wind speed. Atmospheric circulation and its seasonal variation determine the general character of the Estonian wind regime over the Atlantic Ocean and Eurasia. However, the Baltic sea itself is a very important factor affecting wind climate, it has an especially strong influence on the wind regime in costal areas. The mean energy density (W/m 2 ) is a wind energy characteristic that is proportional to the third power of wind speed and describes energy available in a flow of air through a unit area. The mean energy density is a characteristic which has practical importance in regional assessment of snowdrift, storm damage and wind energy

    Energy policy, environmental protection and economy form a triangle of tightly linked sectors, and any solution of some energy problem can be solved only in the light of all the above mentioned factors. There are several energy master plans for Estonia, the first of them dating back to the years of the Soviet Union and ending the list with the plan to cover the years up to 2000. By now the basic principles of the Estonian energy policy have been prepared and Estonian Energy Concept is being worked out. The main goal of Estonian energy policy is ensure an effective and environmentally benign energy supply for the country. It means safety in energy supply, effective production and supply together with sufficient environmental protection. Energy Council in the role of an advisory voluntary organization for inspection of the energy system and finding measures to improve its efficiency is established with parliament members included. The Estonian Energy Research Institute and the Oil--Shale Research Institute serve as a scientific advisory board for the government in energy policy. It's important to emphasise that privatisation is no panacea, solving all the problems, and therefore we are facing hard to move in the right direction, satisfying all the consumers of energy

    Full Text Available The article describes logistics survey in Estonia carried out in 2007 as a part of the LogOnBaltic project. The level of logistics in Estonian manufacturing, trading and logistics companies is explored through logistics costs, performance indicators, outsourcing, ICT use and logistics self-estimation of the companies responded. Responses from 186 Estonian companies were gathered through a web-based survey (38% of manufacturing, 38% of trading and 24% of logistics sector. Logistics costs as the percentage of turnover make in average 13.8% in manufacturing and 13.3% in trading. Transportation and inventory carrying cost form around 70% of overall logistics costs. Considering the logistics indicators surveyed, Estonian companies show up with relatively low perfect order fulfillment rates, short customer order fulfillment cycles and effective management of cash flows. The most widely outsourced logistics function is international transportation followed by domestic transportation, freight forwarding and reverse logistics. By 2010, the outsourcing of IT systems in logistics followed by inventory management, warehousing and product customization is expected to increase more substantially. The awareness of logistics importance is still low among Estonian companies. Only 27–44% of those agree that logistics has a considerable impact on profitability, competitive advantage, top management or customer service level.

    2013-06-01

    Full Text Available The article examines the cultural situation following postmodernism in the first decade of the 21st century. To characterise this situation, the umbrella term “post-postmodernism” is used, as well as “neomodernism”, “altermodern”, “metamodernism”, “hypermodernity”, “performatism”, “critical realism” etc. All these approaches are, in a wider sense, united by their aim of opposing postmodernist cynicism and irony, and bringing back truth, simplicity and clarity. It has also been found that literature has returned or is returning to realism, and various cultural phenomena are emerging, which have been designated by the concept “new sincerity”.In descriptions of the current cultural situation, this trend seeking truth and simplicity is supported by approaches which emphasise the significance of technological developments during the last decade. A prominent figure here is Alan Kirby, who launched the term “digimodernism”, mainly linked with the adaptation and spread of Web 2.0 at the beginning of the 21st century: the blogosphere, Wikipedia, Twitter and Facebook.The article seeks answers to the question of whether we can talk about digimodernism in Estonian literature in the 2000s. In the 1990s Estonian writers were quite reluctant to undertake computer-technological experiments, and there are only a few examples of Estonian digital literature, whereas a change occurred in the 2000s. Many Estonian writers have had and still have their own blogs and surprisingly many have joined Facebook. The term “twitterature” is also familiar to Estonian writers. The article tackles the dominant topics in the blogs of Estonian writers and analyses their possible collective creative work on Facebook. A question is raised as to whether it is possible that the fragmentary narrative structure of blogs and Facebook has influenced mainstream literature.The article concludes that one essential change in Estonian literature in the

It is a qualitative study aiming at understanding the significance of breastfeeding among mothers and primiparous daughters, as well as identifying how the mother perceive herself as a means of support for her primiparous daughter and vice versa. The historic social construction of women for maternity has been used as a theoretical referential. The sample was made up of 10 women--five primiparous daughters and their mothers. The participation of the mother in her daughter's maternity was "to be along with her", sharing knowledge and life experiences.

    Full Text Available Purpose – The study is a contribution to the validation of the 15 items and 5 subscales Transformational Leadership Scale (TLS proposed by Rafferty and Griffin (2004. Design/methodology/approach – The sample includes participants from different levels of the Estonian Defence Forces (EDF military hierarchy (N=2570. The structure of the TLS was examined by using exploratory and confirmatory factor analyses. Additionally ANOVA was used to compare the results between different subsamples. Findings – TLS showed satisfactory reliability. Confirmatory factor analyses found TLS as valid five dimensions instrument to measure transformational leadership in the Estonian military context. Different management levels showed different emphases among the dimensions of transformational leadership. Research and practical limitations/implications – TLS will be an important tool to use in transformational leadership research in the Estonian military context and beyond. Additionally, the current research contributes to the development of alternative measurement tools besides the most commonly used MLQ. The limitation of the work will be the rather homogenous sample from the Estonian military, however it will open the door for the subsequent research using different samplings. Originality/value – The current research found TLS to be a reliable and valid instrument, very short and therefore easy to administrate, having the possibility to use it with five dimensional and as one general transformational instrument as well.

    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.

    The objective of this research was to determine the prevalence, risk factors and consequent effect of dystocia on lactation performance in Holstein dairy cows in Iran. The data set consisted of 55,577 calving records on 30,879 Holstein cows in 30 dairy herds for the period March 2000 to April 2009. Factors affecting dystocia were analyzed using multivariable logistic regression models through the maximum likelihood method in the GENMOD procedure. The effect of dystocia on lactation performance and factors affecting calf birth weight were analyzed using mixed linear model in the MIXED procedure. The average incidence of dystocia was 10.8% and the mean (SD) calf birth weight was 42.13 (5.42) kg. Primiparous cows had calves with lower body weight and were more likely to require assistance at parturition (pdystocia than male calves (pdystocia than singletons (pdystocia at calving compared with those that did not (p<0.05).

    Flue gas emissions from pulverized oil shale fired boilers of Estonian and Baltic power plants have been studied. The concentrations of NO x , CO, C x H y , HCI, Hf and polycyclic aromatic hydrocarbons in flue gases have been found to be relatively low and acceptable according to German emission limits, for instance. Desulphurization degree of flue gases by SO 2 absorption with ash has been found to vary defending on boiler type and operation conditions. In spite of significant sulphur capture (average values for different boilers in the range between 68 and 77 % of the initial sulphur content of the fuel), SO 2 concentrations in flue gases remain still very high (up to 2600 mg/m 3 , 10% O 2 ). Very high concentrations of particles, especially at Estonian Power Plant (up o 6250 mg/m 3 , 10 % 0 2 ) have been detected. Heavy metal emissions were too high by the reason of particle control insufficiency as well. Yearly emission estimates of this study support the former Estonian ones within the range of 10-15 %.

    It is well observed that feeding energy-dense diets in dairy cows during the dry period can cause metabolic imbalances after parturition. Especially dairy cows with high body condition score (BCS) and fed an energy-dense diet were prone to develop production diseases due to metabolic disturbances postpartum. An experiment was conducted to determine the effects of an energy-dense diet and nicotinic acid (NA) on production and metabolic variables of primiparous and multiparous cows in late pregnancy and early lactation which were not pre-selected for high BCS. Thirty-six multiparous and 20 primiparous German Holstein cows with equal body conditions were fed with energy-dense (60% concentrate/40% roughage mixture; HC group) or adequate (30% concentrate/70% roughage mixture; LC group) diets prepartum. After parturition, concentrate proportion was dropped to 30% for all HC and LC groups and was increased to 50% within 16 days for LC and within 24 days for HC cows. In addition, half of the cows per group received 24 g NA supplement per day and cow aimed to attenuate the lipid mobilisation postpartum. Feeding energy-dense diets to late-pregnant dairy cows elevated the dry matter (p metabolic deviation postpartum as the effects of prepartum concentrate feeding were not carried over into postpartum period. Multiparous cows responded more profoundly to energy-dense feeding prepartum compared with primiparous cows, and parity-related differences in the transition from late pregnancy to lactation were obvious pre- and postpartum. The supplementation with 24 g NA did not reveal any effect on energy metabolism. This study clearly showed that energy-dense feeding prepartum did not result in metabolic imbalances postpartum in multiparous and primiparous cows not selected for high BCS. A genetic predisposition for an anabolic metabolic status as indicated by high BCS may be crucial for developing production diseases at the onset of lactation.

    Due to global warming and environment pollution because of widespread use of fossil fuels there are already tendencies to stabilize and decrease the consumption of these energy resources and take into use more renewable energy resources. Estonian Biofuels Association (EBA) is a non-profit association, which was founded on 8. of May 1998 in Tallinn. The EBA is an independent and voluntary alliance of its members. Fields of activity of the EBA are by biofuels research, developing and evaluation to engage environmental, biofuels and energy saving. EBA members are: energy consultants, scientists, as well as fuel suppliers, DH-companies, technology suppliers, energy service companies etc. The members of EBA are involved in different projects in Estonia, where biomass are produced and used for heating, where wood, waste, peat, rape oil and biogas resources are examined and put into use, and also projects which deal with energy saving and environment friendly equipment production for using biofuels. During our short experience we have noticed that people in Estonia have become more aware of biomass and their use, so the development of environment friendly and sustainable energetics will continue in Estonia. Available biofuels in Estonia could compete with fossil fuels if burnt rationally with high technology equipment. EBA members are convinced that biomass have perspective and that they could play an important role in improving Estonian economic and environmental situation. Modem biomass combustion devices are taken into use more the faster general wealth increases and EBA can raise people's awareness of bio fuel subject through special, courses and media. We want Estonian energy policy to develop towards widespread use of renewable energy resources, which would save energy and environment improve nation's foreign trade balance and create jobs mainly in rural areas

    In the end of the Soviet period in the 1980s, a long-term energy programme for Estonia was worked out. The energy system was planned to be based on nuclear power and the share of domestic alternative sources of energy was low. The situation has greatly changed after the re-establishment of the Estonian independence, and now wood and peat fuels play an important role in the energy system. Energy consumption in Estonia decreased during the period 1970-1993, but this process has less influenced the consumption of domestic renewable fuels - peat and wood. It means that the share of these fuels has grown. The investment on substitution of imported fossil fuels and on conversion of boiler plants from fossil fuels to domestic fuels has reached the level of USD 100 million. The perspectives of the wood energy depend mainly on two factors; the resources and the price of wood energy compared with other fuels. The situation in wood market influences both the possible quantities and the price. It is typical that the quickly growing cost of labour power in Estonia is greatly affecting the price of energy wood. Though the price level of fuel peat and wood chips is lower than the world market price today, the conditions for using biofuels could be more favourable, if higher environmental fees were introduced. In conjunction with increasing utilisation of biofuels it is important to evaluate possible emissions or removal of greenhouse gases from Estonian forests 3 refs.

    Stillbirth is an economically important trait on dairy farms. Knowledge of the consequences of, and the economic losses associated with stillbirth can help the producer when making management decisions. The objectives of this study were to determine the effects of stillbirth on productive and reproductive performance as well as financial losses due to stillbirth incidence in Iranian Holstein dairy farms. Economic and performance data were collected from nine Holstein dairy farms in Isfahan and Khorasan provinces of Iran from March 2008 to December 2013. The final data set included 160 410 calving records from 53 265 cows. A linear mixed model was developed to evaluate the effects of stillbirth on performance of primiparous and multiparous cows separately and overall. An economic model was used to estimate the economic losses due to stillbirth. The incidence of stillbirth cases per cow per year was 4.2% on average (3.4% to 6.8% at herd level). The least square means results showed that a case of stillbirth significantly (P0.05). Overall, a case of stillbirth reduced 305-day milk yield by 544.0±76.5 kg/cow per lactation. Stillbirth had no significant effects on 305-day fat and protein percentages in either primiparous or multiparous cows. Overall, cows that gave birth to stillborn calves had significantly increased days open by 14.6±2.6 days and the number of inseminations per conception by 0.2 compared with cows that gave birth to live calves (Pfinancial losses associated with stillbirth incidence averaged US$ 938 per case (range from $US 767 to $US 1189 in the nine investigated farms). The loss of a calf was not the only cost associated with stillbirth, as it accounted for 71.0% of the total cost. The costs of dystocia (7.6%) and culling and replacement expenses (6.3%) were the next most important costs associated with stillbirth. These results can be used to assess the potential return from management strategies to reduce the occurrence of stillbirths.

    Although cowside testing strategies for diagnosing hyperketonemia (HYK) are available, many are labor intensive and costly, and some lack sufficient accuracy. Predicting milk ketone bodies by Fourier transform infrared spectrometry during routine milk sampling may offer a more practical monitoring strategy. The objectives of this study were to (1) develop linear and logistic regression models using all available test-day milk and performance variables for predicting HYK and (2) compare prediction methods (Fourier transform infrared milk ketone bodies, linear regression models, and logistic regression models) to determine which is the most predictive of HYK. Given the data available, a secondary objective was to evaluate differences in test-day milk and performance variables (continuous measurements) between Holsteins and Jerseys and between cows with or without HYK within breed. Blood samples were collected on the same day as milk sampling from 658 Holstein and 468 Jersey cows between 5 and 20 d in milk (DIM). Diagnosis of HYK was at a serum β-hydroxybutyrate (BHB) concentration ≥1.2 mmol/L. Concentrations of milk BHB and acetone were predicted by Fourier transform infrared spectrometry (Foss Analytical, Hillerød, Denmark). Thresholds of milk BHB and acetone were tested for diagnostic accuracy, and logistic models were built from continuous variables to predict HYK in primiparous and multiparous cows within breed. Linear models were constructed from continuous variables for primiparous and multiparous cows within breed that were 5 to 11 DIM or 12 to 20 DIM. Milk ketone body thresholds diagnosed HYK with 64.0 to 92.9% accuracy in Holsteins and 59.1 to 86.6% accuracy in Jerseys. Logistic models predicted HYK with 82.6 to 97.3% accuracy. Internally cross-validated multiple linear regression models diagnosed HYK of Holstein cows with 97.8% accuracy for primiparous and 83.3% accuracy for multiparous cows. Accuracy of Jersey models was 81.3% in primiparous and 83

    Full Text Available The thyroid gland is one of the major endocrine glands which plays an important role in vital balance of the body by secreting two hormones, T3 and T4. Because effects of these two hormones affect the activity of many body organs, in this survey the effects of these two hormones on the return of ovarian activity in Holstein cows were examined. For this purpose, 60 primiparous cows (having one pregnancy and 60 multiparous (having two or more pregnancies were considered for this survey. In both groups, the blood samples were taken 10 days before parturition and 10 to 20 days after parturition.  After centrifugation and serum separation, samples were stored at -20 o C. Afterwards in laboratory, T3 and T4 values were measured by using ELISA kit. The results indicate that the values of T3 and T4 in primiparous cows in the prenatal and postpartum period were more than multiparous cows (p

    To estimate the relationship between heat stress during the last 60 days prepartum, body condition score and certain reproductive traits in the subsequent lactation of Holstein cows, 564 multiparous cows and 290 primiparous cows from four dairy herds were used in a hot, humid region. Maximum prepartum degree days were estimated to quantify the degree of heat stress. Multiple regressions analyses and logistic regression analysis were performed to determine the effect of prepartum heat stress and body condition change on reproductive parameters, which were obtained from DHIA forms at the end of the lactation. Multiparous and primiparous cows which gained body condition score from calving to 60 d postpartum exhibited 28 and 27 fewer days open (P 0.05) of heat stress measurement on days open or services per conception in either multiparous or primiparous cows. During hotter months of calving, multiparous cows showed higher services per conception and primiparous cows showed higher days open and services per conception (P score. Multiparous cows with high body condition score at calving were 1.47 times more likely to present a very difficult calving than cows that calved in October (P reproductive performance was not affected by cumulative prepartum heat stress although it was associated with very difficult calving score.

    Full Text Available The objective of this study was to determine and evaluate the effect of parity on the fatty acids groups’ proportion in Holstein cows’ milk during the first phase of lactations, with an emphasis on its potential importance for consumer health. A total of 25 Holstein cows, 9 primiparous, 9 in the 2nd, and 7 in the 3rd and subsequent parity, were observed and sampled at 7-day intervals through the first 17 weeks of lactation. The percentage proportion of saturated (hypercholesterolemic and volatile as its components and unsaturated (monounsaturated and polyunsaturated as its components fatty acids in the samples of milk fat (n=425 was determined. The effects of parity and negative energy balance, as well as regression, on the lactation week and the fat to protein ratio were evaluated using SAS 9.3. A significantly (P<0.01 lower proportion of unhealthy hypercholesterolemic fatty acids was detected in primiparous cows (-2.67 % and those in the 3rd and subsequent lactation (-2.94 % compared to the 2nd lactation, as well as a simultaneously higher proportion of healthy unsaturated fatty acids (+2.07, respectively +3.08 %. The determined relationships corresponded to organism stress evoked by the initiation of milk production and its maintenance in higher parities. Therefore, the generally required prolongation of dairy cows’ longevity can influence on the quality of raw milk, especially considering composition of fatty acids.

    The objective of this study was to investigate the genetic relationship between body condition score (BCS) and reproduction traits for first-parity Canadian Ayrshire and Holstein cows. Body condition scores were collected by field staff several times over the lactation in herds from Québec, and reproduction records (including both fertility and calving traits) were extracted from the official database used for the Canadian genetic evaluation of those herds. For each breed, six 2-trait animal models were run; they included random regressions that allowed the estimation of genetic correlations between BCS over the lactation and reproduction traits that are measured as a single lactation record. Analyses were undertaken on data from 108 Ayrshire herds and 342 Holstein herds. Average daily heritabilities of BCS were close to 0.13 for both breeds; these relatively low estimates might be explained by the high variability among herds and BCS evaluators. Genetic correlations between BCS and interval fertility traits (days from calving to first service, days from first service to conception, and days open) were negative and ranged between -0.77 and -0.58 for Ayrshire and between -0.31 and -0.03 for Holstein. Genetic correlations between BCS and 56-d nonreturn rate at first insemination were positive and moderate. The trends of these genetic correlations over the lactation suggest that a genetically low BCS in early lactation would increase the number of days that the primiparous cow was not pregnant and would decrease the chances of the primiparous cow to conceive at first service. Genetic correlations between BCS and calving traits were generally the strongest at calving and decreased with increasing days in milk. The correlation between BCS at calving and maternal calving ease was 0.21 for Holstein and 0.31 for Ayrshire and emphasized the relationship between fat cows around calving and dystocia. Genetic correlations between calving traits and BCS during the subsequent

    Full Text Available Since its independence in 1991 Estonia has successfully overpassed the challenges of the transition period being in the present of one the most technologically developed nations of Europe. The present research is intended to evaluate the relationship between Estonian pro-market regulation, entrepreneurship and innovation. In order to reach relevant conclusions in this regard there have been used both qualitative and quantitative methods of analysis. In such a way, it could be comprehensively reviewed the process of Estonian economic development from a relatively underdeveloped USSR republic to an advanced innovation driven economy. The results show that pro-market governmental regulation has favourably influenced Estonian entrepreneurship, while it fostered country’s innovation capacities. It has been concluded that the economic “miracle” of Estonia has been at a great extent determined by proper government regulation oriented towards economic liberalisation.

    When making the decision about whether or not to breed a given cow, knowledge about the expected outcome would have an economic impact on profitability of the breeding program and net income of the farm. The outcome of each breeding can be affected by many management and physiological features that vary between farms and interact with each other. Hence, the ability of machine learning algorithms to accommodate complex relationships in the data and missing values for explanatory variables makes these algorithms well suited for investigation of reproduction performance in dairy cattle. The objective of this study was to develop a user-friendly and intuitive on-farm tool to help farmers make reproduction management decisions. Several different machine learning algorithms were applied to predict the insemination outcomes of individual cows based on phenotypic and genotypic data. Data from 26 dairy farms in the Alta Genetics (Watertown, WI) Advantage Progeny Testing Program were used, representing a 10-yr period from 2000 to 2010. Health, reproduction, and production data were extracted from on-farm dairy management software, and estimated breeding values were downloaded from the US Department of Agriculture Agricultural Research Service Animal Improvement Programs Laboratory (Beltsville, MD) database. The edited data set consisted of 129,245 breeding records from primiparous Holstein cows and 195,128 breeding records from multiparous Holstein cows. Each data point in the final data set included 23 and 25 explanatory variables and 1 binary outcome for of 0.756 ± 0.005 and 0.736 ± 0.005 for primiparous and multiparous cows, respectively. The naïve Bayes algorithm, Bayesian network, and decision tree algorithms showed somewhat poorer classification performance. An information-based variable selection procedure identified herd average conception rate, incidence of ketosis, number of previous (failed) inseminations, days in milk at breeding, and mastitis as the most

    Full Text Available The study was focussed on the relationships between ethnic self-esteem and various indicators of intergroup attitudes in a representative sample of adult population of Estonia (N=1142. Attitudinal variables that discriminated most between persons with high and low ethnic self-esteem were identified. Among Estonians ethnic self-esteem was related to positive ingroup bias, readiness for outgroup contact, perceived threat from the outgroup, attitudes to non-Estonian minority, and attitudes toward minority integration. Among non-Estonians ethnic self-esteem was related to readiness for outgroup contact, ethnic sterotypes, and various attitudes towards minority integration. An attempt was made to reconstruct the system of intergroup attidues of prototypical persons with high and low ethnic selfesteem and to describe psychological implications of high and low ethnic self-esteem for members of majority and minority groups. Various theoretical models (social identity theory, integrated threat theory, social dominane theory were used for interpretation of the results.

    Full Text Available The objective of this research was to determine the prevalence, risk factors and consequent effect of dystocia on lactation performance in Holstein dairy cows in Iran. The data set consisted of 55,577 calving records on 30,879 Holstein cows in 30 dairy herds for the period March 2000 to April 2009. Factors affecting dystocia were analyzed using multivariable logistic regression models through the maximum likelihood method in the GENMOD procedure.

    This study examined the effect of two feeding levels during the antepartum and postpartum period on reproductive performance and blood metabolites (glucose, non-esterified fatty acids (NEFA), insulin) in primiparous Holstein and Swedish Red (SRB) cows, in order to identify possible differences in the way these breeds respond to negative energy balance after calving. A total of 44 cows (22 Holstein, 22 SRB) kept in a loose housing system were included in the study. The control group (HE, n = 23) was fed a diet for high-producing cows (target 35 kg/d energycorrected milk, ECM). A lower feeding intensity (LE, n = 21) was achieved by giving -50% concentrate to target 25 kg/d ECM. Diets were implemented 30 days before expected calving and the cows were monitored for 120 days postpartum. Milk yield and composition, dry matter intake (DMI), live body weight and body condition score (BCS) were assessed to calculate the weekly energy balance (residual feed intake). Blood sampling started before diet implementation and was repeated every 2 weeks until Day 60 postpartum and then once monthly until Day 120. Plasma was kept at -20 °C until analysis for glucose, insulin and NEFA concentrations. Mixed linear models were used to analyse data (SAS 9.3; PROC MIXED). Holstein cows had lower mean energy balance than SRB cows (-4.7 ± 1.4 and -0.9 ± 1.4 MJ, respectively; p = 0.05). SRB cows had higher (pcows (2.7 ± 0.1) and also higher plasma glucose concentrations from Day -30 to Day 120 relative to parturition (4.1 ± 0.1 and 4.2 ± 0.1 log ; mg/100 ml, respectively; p cows than in Holsteins at Day -14 before calving, indicating higher mobilisation of lipid from adipose tissue already before calving. In contrast, Holstein cows had higher NEFA at Day 14 postpartum than SRB cows (p cows prioritise milk production to a larger extent than SRB cows, resulting in a less balanced metabolic profile.

Twelve late lactating Holstein primiparous cows including four cows equipped with a rumen cannula, averaging 210 ± 20 d in milk and weighing 575 ± 50 kg were randomly assigned in a 4x4 Latin square design. During each of four 21-d periods, cows were fed 4 total mixed diets that were varied in the forage sources: 1 50% corn silage (CS, 2 35% corn silage + 15% wheat straw (CSW, 3 35% corn silage + 15% alfalfa hay (CSA, 4 25% corn silage + 10% wheat straw + 15% alfalfa hay (CSWA. The production of milk averaged 18.55, 20.41 and 20.06 kg/d for unadjusted milk production, 4% fat corrected milk and solid corrected milk, respectively, and was not affected by treatments. Likewise, milk composition or production of milk components was not affected by diets and averaged 4.69% fat, 3.66% protein, 4.51% lactose, 866 g/d fat, 665 g/d protein, 824 g/d lactose. Treatments had no effect on in situ NDF soluble, degradable and potential degradability of all diets, whereas the effective degradability (ED of NDF was greater for cows fed CS diet than for cows fed CSW, CSA and CSWA diets (P<0.05. These values suggested that the partial replacement of corn silage with alfalfa hay and/or wheat straw has no unfavourable effect on the productive parameters.

  4. The Estonian study of Chernobyl cleanup workers. I. Introduction

    1999-01-01

    The most comprehensive epidemiological project ever performed in Estonia - The Estonian Study of Chernobyl Cleanup Workers - was the joint effort of researchers from Estonia, Finland and USA. Until September 1999, the results of this study were published in English only. To familiarize the readership of 'Eesti Arst' with the major study findings, the abridged versions of four original papers from 'Radiation Research' are presented in the current issue of the journal. For the Estonian epidemiologists, the work under this project that consists of eight sub projects was a real challenge. In the course of the study, skills were developed in writing a study protocol, preparing a questionnaire, progress reporting, documenting the structure of databases, record linkage, and problem solving. It was an exciting experience to work with top scientists like William Bigbee, John Boice, Timo Hakulinen, Ronald Jensen and Gayle Littlefield. (author)

    Full Text Available The article reports the results of the study on the critical success factors and related information needs in Estonian industry conducted in 1999. Data were collected by interviews with 27 managers and engineers from 16 manufacturing companies in various industries. Most of the critical success factors taken up were related to marketing, information management, quality management, product development and technological innovations. The information needs of managers and engineers were related to competitors, customers, markets, technology, regulations, etc. Some identified CSFs expressed also priorities for development by Estonian economic authorities: to support the implementation of new technologies and introduction of quality management methods. The finding that information management was perceived as a very critical area supports the result of the recent Finnish study on CSFs.

This study aimed to determine the effect of audiovisual distraction (VR on anxiety in primiparous women during episiotomy repair. Materials and Methods: This clinical trial was conducted on 30 primigravida from May to July 2012 in the maternity unit of the Omolbanin Hospital, Mashhad city, Iran. The samples were divided randomly into two groups with the toss of a coin. Anxiety were evaluated by the numeric 0-10 anxiety self-report, in the first and during labor. However, after delivery, anxiety was measured with the Spilberger scale. Mann-Whitney, Chi-square, Fisher tests, and repeated-measures analysis of variance were used to analyze data. Results: Anxiety scores were not significantly different between the two groups (wearing video-glass and receiving routine care, but anxiety scores were lower in the intervention group during and after repair (P = 0.000. Conclusions: VR are safe, appropriate, and nonpharmacologic to decrease and manage the anxiety-associated episiotomy.

    Although severe gynaecological pathology during delivery and negative outcome have been shown to be related with posttraumatic stress disorder (PTSD) little is known about traumatic experiences following regular delivery, at the expected time and with a healthy child. The objective of our study was to determine the prevalence of PTSD during postpartum period after vaginal delivery and its risk factors. The sample included 126 primiparous women. Monthly, for the next three months, the women were assessed for PTSD using the gold standard interview for PTSD, Clinician-Administered PTSD Scale (CAPS). Risk factors were assessed including sociodemographic variables, personal medical history and clinical variables. After the first month, 2.4% women had acute full PTSD and another 9.5% had clinically significant level of PTSD symptoms. Following the second and the third month, partial PTSD was found in 5.9% and 1.3% of the women, respectively, and none of participants had full PTSD. Obstetrical interventions were the only significant risk factor for the development of PTSD. Symptoms of postpartum PTSD are not rare after a traumatic delivery, and associated with specific obstetrical risk factors. Awareness of these risk factors may stimulate interventions to prevent this important and neglected postpartum disorder.

    Full Text Available The aim of this study is to analyse the efficiency of Estonian grain farms after Estonia’s transition to a market economy and during the accession period to the European Union (EU. The non-parametric method Data Envelopment Analysis (DEA was used to estimate the total technical, pure technical and scale efficiency of Estonian grain farms in 2000–2004. Mean total technical efficiency varied from 0.70 to 0.78. Of the grain farms 62% are operating under increasing returns to scale. Solely based on the DEA model it is not possible to determine optimum farm scale and the range of Estonian farm sizes operating efficiently is extensive. The most pure technically efficient farms were the smallest and the largest but the productivity of small farms is low compared to larger farms because of their small scale. Therefore, they are the least competitive. Since pre-accession period to the EU, large input slacks of capital have replaced the former excessive use of labour and land. This raises the question about the effects on efficiency of the EU’s investment support schemes in new member states.;

    2011-01-01

    Full Text Available In April 2007, the Estonian Government moved a memorial commemorating the Soviet liberation of the country from the Nazis to a less prominent and visible location in Tallinn. This decision triggered rioting among Russian-speaking minorities and cyber terrorism targeting Estonia's critical economic and political infrastructure. Drawing upon the Estonian cyber attacks, this article argues that globalization and the Internet have enabled transnational groups—such as the Russian diaspora—to avenge their grievances by threatening the sovereignty of nation-states in cyberspace. Sophisticated and virtually untraceable political "hacktivists" may now possess the ability to disrupt or destroy government operations, banking transactions, city power grids, and even military weapon systems. Fortunately, western countries banded together to effectively combat the Estonian cyber attacks and minimize their effects. However, this article concludes that in the age of globalization, interdependence, and digital interconnectedness, nation-states must engage in increased cooperative cyber-defense activities to counter and prevent devastating Internet attacks and their implications.

    2010-12-01

    Full Text Available The article examines the exiled Estonian politicians in the European Movement in the early Cold War period. The ultimate goal of exiled Estonians was to restore their state’s independence. In order to promote this, Estonian leaders sought connections with Western leaders. The European Movement was the only organisation involving actors from both the East and the West, and this corresponded to the Estonian discourse on Europe as a whole. Therefore, the European Movement was appreciated, although its limited opportunities for decisive actions were also recognised. East and West European interest in the European Movement declined as West European integration rapidly intensified through the European Coal and Steel Community (ECSC and particularly after the January 1952 Eastern European Conference in London. By 1957, disappointment in the inability of European unification to help regain Estonian independence became evident.

  17. Maternal anxiety and physiological reactivity as mechanisms to explain overprotective primiparous parenting behaviors.

    Kalomiris, Anne E; Kiel, Elizabeth J

    2016-10-01

    In this study, we sought to determine whether the affective and physiological experience of primiparous, or first-time, motherhood is distinct from multiparous motherhood, how the child's level of inhibited temperament impacts it, and if such a temperament results in overprotective parenting behaviors. A total of 117 mothers and their 24-month-old toddlers participated in novelty tasks designed to elicit parenting behaviors and toddler's typical fear reactions. Mothers also completed a battery of questionnaires. Results suggest that primiparous mothers experienced more worry, which was associated with increased overprotective parenting behaviors. Primiparous mothers also demonstrated greater physiological (i.e., cortisol) reactivity while watching their first-born children interact with novel stimuli, but how this related to overprotective parenting was dependent on the child's level of inhibition. Specifically, primiparous mothers displayed more cortisol reactivity with their uninhibited toddlers, which indirectly linked parity to less overprotective parenting behaviors. Primiparous mothers of highly inhibited toddlers displayed greater overprotective parenting behaviors, independent of maternal cortisol reactivity. The results indicate that the transition to motherhood is a unique experience associated with greater worry and physiological reactivity and is meaningfully influenced by the toddler's temperament. Distinctions in both observed and self-reported overprotective parenting are evident through considering the dynamic interaction of these various aspects.

    The objective of this study was to identify genomic regions and candidate genes associated with feed efficiency in lactating Holstein cows. In total, 4,916 cows with actual or imputed genotypes for 60,671 single nucleotide polymorphisms having individual feed intake, milk yield, milk composition, and body weight records were used in this study. Cows were from research herds located in the United States, Canada, the Netherlands, and the United Kingdom. Feed efficiency, defined as residual feed intake (RFI), was calculated within location as the residual of the regression of dry matter intake (DMI) on milk energy (MilkE), metabolic body weight (MBW), change in body weight, and systematic effects. For RFI, DMI, MilkE, and MBW, bivariate analyses were performed considering each trait as a separate trait within parity group to estimate variance components and genetic correlations between them. Animal relationships were established using a genomic relationship matrix. Genome-wide association studies were performed separately by parity group for RFI, DMI, MilkE, and MBW using the Bayes B method with a prior assumption that 1% of single nucleotide polymorphisms have a nonzero effect. One-megabase windows with greatest percentage of the total genetic variation explained by the markers (TGVM) were identified, and adjacent windows with large proportion of the TGVM were combined and reanalyzed. Heritability estimates for RFI were 0.14 (±0.03; ±SE) in primiparous cows and 0.13 (±0.03) in multiparous cows. Genetic correlations between primiparous and multiparous cows were 0.76 for RFI, 0.78 for DMI, 0.92 for MBW, and 0.61 for MilkE. No single 1-Mb window explained a significant proportion of the TGVM for RFI; however, after combining windows, significance was met on Bos taurus autosome 27 in primiparous cows, and nearly reached on Bos taurus autosome 4 in multiparous cows. Among other genes, these regions contain β-3 adrenergic receptor and the physiological candidate gene

  19. Estonian Language of Technology as a Factor Supporting the Evolution of Engineering Thinking

    Directory of Open Access Journals (Sweden)

    Mägi, Vahur

    2013-03-01

    Full Text Available Casual mention of teaching technology subjects in Estonian schools dates back several centuries. Navigation and construction were amongthe earliest professional skills that were taught. As both of them required mathematical thinking skills, teaching the subjects was usually accompanied by explaining the principles of mathematics. The first technology book in Estonian was published about two centuries ago and it dealed with geodesy. The earliest Estonian glossaries of technological terminology were published in the fields of physics and chemistry. The rise of Estonian as a language of higher education and science in the country came about in the 1920s and 1930s. Faculty members of the Tallinn School of Technology then published the first textbooks composed in the Estonian language for students of technology. The Estonian Society for Technology and the Estonian Association of Engineers became seriously involved in linguistic activities. Together with the Vocational Teachers’ Assembly of Tartu they published an illustrated technology glossary for machinery and tools terms. It was followed by a glossary of construction and building terms, compiled under the lead of the University of Technology. In addition, journals of technology introducedinnovations in the lexicon of technology to the general public. The postwar period in the development of the lexicon of technical terms was of little significance at first. A surge in language creativity could be detected in the 1960s, when terminology became a target of constantly growing attention to the development of technology lexicon. Series of technology glossaries were published. This tendency has continued to this day.

    Crossbreed dairy breeds, such as Holstein × dairy type of Simmental, have been generally used to improve fertility, udder health, and longevity of dairy herds. The aim was to compare the reproductive performance and survival of Holstein and Holstein × Simmental crossbred cows. Data from two farms were used as follows: one located in Bom Retiro, in the state of Santa Catarina, Brazil. and another in Carambeí, Paraná state. Information concerning birth, inseminations, and parity date were obtained from the management software of the farms, generating information regarding the calving interval, days between calving to first service, conception rate, and age at first calving. At one of the farms, calving was monitoring to quantify dystocia. Live weight as well as body condition score (BCS) of cows and information of culling were obtained to determine the survival rate. Data were analyzed by variance analysis and by logistic regression. Crossbred Holstein × Simmental cows had better reproductive performance than the Holstein cows, characterized by lower calving interval (381 vs. 445 days), higher conception rate (37.3 vs. 33.6 %), and shorter calving to first service interval (65 vs. 89 days). These results were related to a higher BCS in crossbred cows (3.63 vs. 2.94 points). Crossbred Holstein × Simmental cows had higher survival rate than Holstein cows on the second parity (83 vs. 92 %). No differences between genetic groups were observed (P > 0.05) for body weight and dystocia. In conclusion, Holstein × Simmental crossbred cows have better reproductive performance and higher survival rate than Holstein cows.

    This study examined the smoking habits and attitudes towards smoking among Estonian physicians. Cross-sectional data for 2668 physicians were gathered by a self-administered postal survey. The current smoking prevalence was 24.9% for male physicians and 10.8% for female physicians. The percentages of ex-smokers were 32.9 and 16.8%, respectively. Smoking prevalence among physicians was below the levels reported for the highest educational bracket of the total population in Estonia. Non-smoking physicians had more unfavourable views towards smoking than those who smoked. The majority of physicians were aware of the association between smoking and various diseases, with significant differences between smokers and non-smokers. Non-smoking physicians were more active in asking patients about smoking habits than those who smoked. Most Estonian physicians, especially those who smoked, failed to perceive themselves as positive role models. This study found a lower prevalence of smoking among physicians compared with the general population, and demonstrated the impact of personal smoking on physicians' attitudes towards smoking. The results provide an important challenge to medical education in Estonia.

  4. Acquisition of noun derivation in Estonian and Russian L1

    2018-04-01

    Full Text Available Acquisition of derivation is not a well-studied area in first language research and a comparative approach to the acquisition of derivation in different languages doesn’t exist. There is no information on how a child acquires derivation in a language with a rich and regular system of derivational patterns, or in a language where derivation is productive, but the system of derivational patterns is opaque. According to general ideas of complexity in a language, the child should start to use simplex stems first and, only after that, complex ones, that is, complexity should increase in the course of acquisition. Our paper is intended to address these issues, based on longitudinal child data from typologically different languages, Estonian and Russian. The results revealed significant differences in the acquisition of noun derivation in the two languages under observation. The system of noun derivation is acquired at a faster pace in Russian, while Estonian children have far fewer noun derivatives in their speech and they use different derivation suffixes with less regularity. Even so, the so-called building block model may be applied for both languages only partially.

    Data regarding hematologic reference intervals (RI) for neonatal calves have not been published yet. The aims of this study were: a) to establish hematology RIs for neonatal Holstein calves, b) to compare them with the RIs for lactating cows, and c) to investigate the relationship of age and gender with the hematologic profile of calves. Two-hundred and fifty-four clinically healthy Holstein calves (1-9days old, from 30 farms) and 82 healthy Holstein cows (between 30 and 150days in milk, from 10 farms) were blood sampled once for a complete blood count evaluation, using the ADVIA 120 hematology analyzer. An additional blood sample was collected from each calf for serum total protein concentration measurement. RIs and age-related RIs were calculated with the Reference Value Advisor freeware. Comparisons between calves and cows and between male and female calves were performed with t-test or Mann-Whitney test. Red blood cell count (RBC), white blood cell count (WBC), neutrophil, lymphocyte and platelet counts in calves were higher, while mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC) were lower than in cows. Lymphocyte and platelets showed a notable increase through age. Finally, female calves had higher RBC, hematocrit and hemoglobin concentration than males. Age-specific RIs should be used for the interpretation of the complete blood count in Holstein calves. Copyright © 2018 Elsevier Ltd. All rights reserved.

Unfortunately most Estonian companies sell peat to intermediaries and cannot influence its price. Estonian peat producers have to choose between either selling peat directly or selling through a central marketing organization. Both systems have their pros and cons. Direct selling gives more freedom to individual producers but is more risky. Central marketing makes cost saving possible and is more effective and stable, but may alienate producers from clients and markets. Whichever marketing system Estonian peat companies choose, the most important elements in their marketing strategy should be: careful market analysis, personal sales, attending trade shows, catalogues, quality service and offering transportation services.

  13. Social-Cognitive Predictors of Exclusive Breastfeeding among Primiparous Mothers in Addis Ababa, Ethiopia.

    Directory of Open Access Journals (Sweden)

    Anteneh Girma Minas

    Full Text Available Despite the presence of high impact interventions to improve infant and young child feeding, only about 52% of mothers in Ethiopia exclusively breastfeed their child for the first six months after delivery. Although the decision to breastfeed a child is ultimately that of the mother, this decision could be influenced by a variety of factors including social-cognitive ones.The objectives of the study were to describe the breastfeeding behaviour of primiparous mothers during their prenatal period in terms of intentions/goals, outcome expectancies, self-efficacy, and socio-structural factors and assess their exclusive breastfeeding (EBF practices as well as identify the social-cognitive predictors of EBF practices among these mothers in Addis Ababa, Ethiopia.A prospective follow up health facility-based study with quantitative methods was used with a sample of 233 primiparous women. Both structured and semi-structured questions were used for collection of data. The Statistical Package for Social Sciences (SPSS version 21 was used for data analysis. Findings at the 95% confidence interval and P-value of 5% were reported as statistically significant.39.1% (n = 59 of the respondents were found to have high breastfeeding self-efficacy, 51.4% (n = 71 have good breastfeeding outcome expectancies, and 6.5% (n = 9 respondents had supportive breastfeeding socio-structural factors. Bivariate correlation analysis showed positive and statistically significant correlation between each of breastfeeding self-efficacy, outcome expectancy, and socio-structural factors, with EBF practice. However, only breastfeeding self-efficacy and outcome expectancies were statistically significant predictors of EBF among the primiparous women when controlling for confounding variables.Health programmes aimed at improving EBF among primiparous mothers should look beyond providing health information alone. Rather improving primiparous women's breastfeeding self-efficacy and

    A total of 1922 first generation crossbred cows born between 2005 and 2012 produced by inseminating purebred Israeli Holstein cows with Norwegian Red semen, and 7487 purebred Israeli Holstein cows of the same age in the same 50 herds were analyzed for production, calving traits, fertility, calving diseases, body condition score, abortion rate and survival under intensive commercial management conditions. Holstein cows were higher than crossbreds for 305-day milk, fat and protein production. Differences were 764, 1244, 1231 for kg milk; 23.4, 37.4, 35.6 for kg fat, and 16.7, 29.8, 29.8 for kg protein; for parities 1 through 3. Differences for fat concentration were not significant; while crossbred cows were higher for protein concentration by 0.06% to 0.08%. Differences for somatic cells counts were not significant. Milk production persistency was higher for Holstein cows by 5, 8.3 and 8% in parities 1 through 3. Crossbred cows were higher for conception status by 3.1, 3.6 and 4.7% in parities 1 through 3. Rates of metritis for Holsteins were higher than the crossbred cows by 7.8, 4.6 and 3.4% in parities 1 to 3. Differences for incidence of abortion, dystocia, ketosis and milk fever were not significant. Holstein cows were lower than crossbred cows for body condition score for all three parities, with differences of 0.2 to 0.4 units. Contrary to comparisons in other countries, herd-life was higher for Holsteins by 79 days. A total of 6321 Holstein cows born between 2007 and 2011 were higher than 765 progeny of crossbred cows backcrossed to Israeli Holsteins of the same ages for milk, fat and protein production. Differences were 279, 537, 542 kg milk; 10.5, 17.7, 17.0 kg fat and 6.2, 12.9, 13.2 kg protein for parities 1 through 3. Differences for fat concentration were not significant, while backcross cows were higher for protein percentage by 0.02% to 0.04%. The differences for somatic cell score, conception rate, and calving diseases other than metritis, were not

    Full Text Available The Mexican Holstein industry has imported Canadian and US (CAN+USA Holstein germplasm for use in two different production systems, the conventional (Conv and the low income system (Lowi. The objective of this work was to study the genetic composition and differentiation of the Mexican Holstein cattle, considering the production system in which they perform and their relationship with the Canadian and US Holstein populations. The analysis included information from 149, 303 and 173 unrelated or with unknown pedigree Holstein (HO animals from the Conv, Lowi and CAN+USA populations, respectively. Canadian and US Jersey (JE and Brown Swiss (BS genotypes (162 and 86, respectively were used to determine if Mexican Holsteins were hybridized with either of these breeds. After quality control filtering, a total of 6,617 out of 6,836 SNP markers were used. To describe the genetic diversity across the populations, principal component (PC, admixture composition, and linkage disequilibrium (r2 analyses were performed. Through the PC analysis, HOxJE and HOxBS crossbreeding was detected in the Lowi system. The Conv system appeared to be in between Lowi and CAN+USA populations. Admixture analysis differentiated between the genetic composition of the Conv and Lowi systems, and five ancestry groups associated to sire’s country of origin were identified. The minimum distance between markers to estimate a useful LD was found to be 54.5 kb for the Mexican HO populations. At this average distance, the persistence of phase across autosomes of Conv and Lowi systems was 0.94, for Conv and CAN+USA was 0.92 and for the Lowi and CAN+USA was 0.91. Results supported the flow of germplasm among populations being Conv a source for Lowi, and dependent on migration from CAN+USA. Mexican Holstein cattle in Conv and Lowi populations share common ancestry with CAN+USA but have different genetic signatures.

    Full Text Available Recession has sharply erected the question of tax burden and the optimal proportion of different kinds of taxes among the incomes of the budget. Indirect taxes and consumption taxes, which proportion is different according to different methodologies, dominate in Estonian state budget. The buoyancy of a tax system based on taxes of that kind is especially weak during the recession. Difficulties concerning the incomes of budget have arisen the necessity for lifting taxes, which is possible as the tax burden is low now. But a sharp question of the optimal level of taxes is going to be raised. A formula for indirect tax optimum according to Ramsey taxes and Slutski decomposition has been proposed in the article.

    Eight calves with osteogenesis imperfecta were born in a Danish Holstein-Friesian herd during a two-year period. In total 92 calves were born (84 normal), and all were sired by a clinically normal Holstein-Friesian bull. The defect was probably due to a de novo dominant mutation present as a gonadal mosaicism in the bull. Affected calves were characterised by multiple fractures, congenital bone deformations, generaljoint laxity, dentinogenesis imperfecta, and light blue sclerae. The skin seemed normal. Electron microscopical studies revealed slightly decreased average diameter of cutaneous collagen fibrils, while the diameter of collagen fibrils in tendons and ligaments was severely reduced. Abnormalities of collagen type I from skin and compact bone were not detected by biochemical analyses

    Edilaine de Paula Batista Mendes

    Full Text Available ABSTRACT Objectives: to compare the pelvic floor muscle strength in primiparous women after normal birth and cesarean section, related to the socio-demographic characteristics, nutritional status, dyspareunia, urinary incontinence, perineal exercise in pregnancy, perineal condition and weight of the newborn. Methods: this was a cross-sectional study conducted after 50 - 70 postpartum days, with 24 primiparous women who underwent cesarean delivery and 72 who had a normal birth. The 9301 PeritronTM was used for analysis of muscle strength. The mean muscle strength was compared between the groups by two-way analysis of variance. Results: the pelvic floor muscle strength was 24.0 cmH2O (±16.2 and 25.4 cmH2O (±14.7 in postpartum primiparous women after normal birth and cesarean section, respectively, with no significant difference. The muscular strength was greater in postpartum women with ≥ 12 years of study (42.0 ±26.3 versus 14.6 ±7.7 cmH2O; p= 0.036 and in those who performed perineal exercises (42.6±25.4 11.8±4.9 vs. cmH2O; p = 0.010, compared to caesarean. There was no difference in muscle strength according to delivery type regarding nutritional status, dyspareunia, urinary incontinence, perineal condition or newborn weight. Conclusion: pelvic floor muscle strength does not differ between primiparous women based on the type of delivery. Postpartum women with normal births, with higher education who performed perineal exercise during pregnancy showed greater muscle strength.

  4. The Category of Time in Fairy Tales: Searching for Folk Calendar Time in the Estonian Fairy Tale Corpus

    Directory of Open Access Journals (Sweden)

    Mairi Kaasik

    2011-03-01

    Full Text Available The article examines how folk calendar holidays are represented in Estonian fairy tales. It introduces some views presented in folklore studies about the concept of time in fairy tales and finds parallels with them in the Estonian context. The analysis relies on the digital corpus of Estonian fairy tales (5400 variants, created from the texts found in the Estonian Folklore Archives by the Fairy Tale Project of the Department of Estonian and Comparative Folklore, University of Tartu. Folk calendar holidays occur in Estonian fairy tales relatively seldom; most often these are holidays that occupy a significant place in the Estonian folk calendar (Christmas, St. John’s Day, Easter, St. George’s Day. Calendar holidays are notably mentioned more often in tale types which remain on the borderline between the fairy tale and the legend or the fairy tale and the religious tale. In Estonian fairy tales, calendar holidays are used on three levels of meaning: (1 the holiday is organically associated with the tale type; it has an essential role in the plot of the tale; (2 to a certain extent, the holiday could be replaced by another holiday having an analogous meaning; (3 the holiday forms an unimportant or occasional addition to the tale.

    The objective of this study was to investigate the effects of niacin and dietary concentrate proportion on body temperature, ruminal pH and milk production of dairy cows. In a 2 × 2 factorial design, 20 primiparous Holstein cows (179 ± 12 days in milk) were assigned to four dietary treatments aimed to receive either 0 or 24 g niacin and 30% (low) or 60% (high) concentrate with the rest being a partial mixed ration (PMR) composed of 60% corn and 40% grass silage (on dry matter basis). Ambient temperature and relative humidity were determined and combined by the calculation of temperature humidity index. Respiration rates, rectal, skin and subcutaneous temperatures were measured. Milk production and composition were determined. Ruminal pH and temperature were recorded at a frequency of 5 min using wireless devices for continuous intra-ruminal measurement (boluses). pH values were corrected for pH sensor drift. The climatic conditions varied considerably but temporarily indicated mild heat stress. Niacin did not affect skin, rectal and subcutaneous temperatures but tended to increase respiration rates. High concentrate reduced skin temperatures at rump, thigh and neck by 0.1-0.3°C. Due to the technical disturbances, not all bolus data could be subjected to statistical evaluation. However, both niacin and high concentrate influenced mean ruminal pH. High concentrate increased the time spent with a pH below 5.6 and ruminal temperatures (0.2-0.3°C). Niacin and high concentrate enhanced milk, protein and lactose yield but reduced milk fat and protein content. Milk fat yield was slightly reduced by high concentrate but increased due to niacin supplementation. In conclusion, niacin did not affect body temperature but stimulated milk performance. High concentrate partially influenced body temperatures and had beneficial effects on milk production.

  7. On the System of Place Name Signs in Estonian Sign Language

    Directory of Open Access Journals (Sweden)

    Liina Paales

    2011-05-01

    Full Text Available A place name sign is a linguistic-cultural marker that includes both memory and landscape. The author regards toponymic signs in Estonian Sign Language as representations of images held by the Estonian Deaf community: they reflect the geographical place, the period, the relationships of the Deaf community with hearing community, and the common and distinguishing features of the two cultures perceived by community's members. Name signs represent an element of signlore, which includes various types of creative linguistic play. There are stories hidden behind the place name signs that reveal the etymological origin of place name signs and reflect the community's memory. The purpose of this article is twofold. Firstly, it aims to introduce Estonian place name signs as Deaf signlore forms, analyse their structure and specify the main formation methods. Secondly, it interprets place-denoting signs in the light of understanding the foundations of Estonian Sign Language, Estonian Deaf education and education history, the traditions of local Deaf communities, and also of the cultural and local traditions of the dominant hearing communities. Both perspectives - linguistic and folkloristic - are represented in the current article.

    A countrywide survey of radon concentrations in Estonian dwellings was carried out during the period 1998-2001. The survey formed a part of the cooperation program on radiation protection between the Estonian Radiation Protection (Kiirguskeskus) Centre and the Swedish Radiation Protection Authority (SSI). The survey included measurements in a number of dwellings representative for Estonia in detached houses and multifamily buildings (only dwellings on the bottom floor were included in the survey). Altogether, radon concentrations were measured in 515 dwellings, a number large enough to be statistically significant. All measurements were made with alphatrack film detectors of the same type that SSI uses in Sweden. The measurements were made during a 2-3 month period during the winter half-year. Two detectors were used in each dwelling. In Estonia there are 0.17 million dwellings in detached houses and 0.45 million in multi apartment buildings. Of the 1.26 million inhabitants in Estonia. 0.36 million live in detached houses and 0.90 million in multi apartment buildings. Most of the latter were built during the Soviet occupation. Of the dwellings in multifamily buildings 30 % are assumed to be situated on the first floor. The mean radon concentration in dwellings in detached hoses, according to the survey results, is 103 Bq/m{sup 3}, in dwellings on the bottom floor in multi apartment buildings it is 78 Bq/m{sup 3}. In 1% of the dwellings the radon concentration exceeded 400 Bq/m{sup 3}. The highest radon concentration found in the study was 1040 Bq/m{sup 3}. Based on the assumption that the average radon concentration in the dwellings in multi-apartment buildings that are not situated on the bottom floor is 30 Bq/m{sup 3}, and that these dwellings constitute 70% of all dwellings in multi apartment buildings, the mean radon concentration in dwellings in multi apartment buildings is calculated to be 44 Bq/m{sup 3}. The mean value for all Estonia dwellings is calculated

    Full Text Available The objectives of this study were to evaluate the relationship between changes in Holstein cow’s body condition score (BCS, acetone and urea content in the milk and cervical mucus (CM and sperm survival in CM. At insemination, samples of milk and CM were collected from 64 Holstein cows. Content of acetone and urea were determined. Sperm motility was assessed subjectively at the beginning and after 30, 60 and 90 minutes of the short-term heat test in CM. Data about evaluation of cow’s BCS were taken from farm evidence. The data set was analyzed using SAS/STAT software. Effect of change in cow’s BCS one month before insemination was significant only in relation to the acetone content in milk (P < 0.05. Higher values of acetone and urea content were found in the CM compared to milk. Higher levels of both metabolites were detected in primiparous cows and in cows on the third and subsequent lactation, resp. in cows inseminated 3 times and more. The highest values of both metabolites negatively affected sperm survival during the short-term heat test, especially after 90 minutes (P < 0.05–0.01. Significant decreases (P < 0.05–0.01 were detected in cows with the highest level of acetone and urea.

    2015-03-01

    Full Text Available The aim of the study was to determine the effect of backfat thickness measured during gestation and after lactation of primiparous and multiparous sows on the value of reproductive traits. Backfat thickness was determined at mating, at 105 day of gestation and after weaning and were correlated with selected reproductive indicators including placenta weight. The study was carried out 20 primiparous and 20 multiparous sows of Polish Landrace breed. The nutrition and housing conditions were the same for all pigs. Backfat and loin depth (P2, P4 , P4 M were measured using PIGLOG 105 device. The evaluation of reproductive performance included the weight of placenta at parturition, the number of born piglets, litter weight, piglet body weight at birth, at 21 and at weaning (28 days. Multiparous sows were characterized by greater fatness than primiparous sows in all periods of use. In all examined sows the backfat depth during gestation increased and decreased after lactation. Those changes were more pronounced in multiparous sows than in primiparous sows (P ≤ 0.01. Multiparous sows born and reared more piglets to 21 and 28 days of life (P ≤ 0.01. There have not been dead piglets in primiparous litters. Litters weight from multiparous sows were higher than from primiparous sows only at birth (P ≤ 0.01 and similar in rest periods of rearing. Individual body weight of piglets from primiparous was higher than that from multiparous sows at 21 and 28 days of life (P ≤ 0.01. Fatness changes during lactation, particularly in multiparous sows, were positively correlated with litter weight at birth and negatively correlated with piglet’s weight at 21 and 28 days of life and their daily gains (P ≤ 0.05. Correlations between placenta weight and backfat thickness during lactation were positive in both groups of sows (P ≤ 0.01.

  14. Periconceptional Heat Stress of Holstein Dams Is Associated with Differences in Daughter Milk Production and Composition during Multiple Lactations.

    Directory of Open Access Journals (Sweden)

    Britni M Brown

    Full Text Available Heat stress at the time of conception affects the subsequent milk production of primiparous Holstein cows; however, it is unknown whether these effects are maintained across multiple lactations. Therefore, the objective of the current study was to examine the relationship between periconceptional heat stress and measurements of milk production and composition in cows retained within a herd for multiple lactations. National Dairy Herd Improvement Association data was obtained from Dairy Records Management Systems. Records included milk production data and milk composition data from over 75,000 and 44,000 Holstein cows, respectively, born between 2000 and 2010 in Florida, Georgia, and Texas. Conception dates were calculated by subtracting 276 d from the recorded birth date. Records for cows conceived within the months of June, July, and August were retained as heat stress conceived (HSC cows; cows conceived within the months of December, January, and February were retained as thermoneutral conceived (TNC contemporaries. Adjusted 305-d mature equivalent milk, protein percent and fat percent were evaluated with a mixed model ANOVA using SAS. Milk production was significantly affected by periconceptional heat stress. When a significant difference or tendency for a difference was detected between the HSC and TNC cows, the TNC produced more milk in all but one comparison. The advantage in milk production for the TNC cows over the HSC cows ranged from 82 ± 42 to 399 ± 61 kg per lactation. Alterations in fat and protein percentage were variable and most often detected in first lactations (first > second or third. Overall, the most striking result of this study is the consistency of the relationship between HSC and milk production. The nature of this relationship suggests that heat stress at or around the time of conception impairs cow milk yield throughout her lifetime.

    Full Text Available The article analyses tale type The Woman as Wolf, which is one of the most popular folk tales in the Estonian Folklore Archives and is represented there both in the form of a fairy tale and in the form of a legend. The vast majority of the versions of The Woman as Wolf were written down in the first part of the 20th century within Estonia and where recorded from Estonians. The article introduces the content of the tale, the origin of the first records from the early 19th century, and the dissemination area of the tale, which remains outside Western Europe: apart from the Estonian versions there are Sami, Karelian, Vepsian, Livonian, Latvian, Lithuanian, Russian, Ukrainian and Belarusian versions. While in almost all the Estonian versions the main protagonist is transformed into a wolf, in most of the versions written down in other areas and ethnic groups, another animal or bird replaces the wolf. The author is of the opinion that the Finnic area is central to the distribution of the folk tale The Woman as Wolf. The animal the woman is transformed into in the plot would not have been a wolf in earlier times. The article provides an explanation why the wolf is predominant in Estonian written sources. For that purpose the ways in which the wolf and werewolf were perceived in earlier Estonian folk belief are introduced. At the end of the article interpretation of the folk tale is provided. The author states that the plot and some of the motifs found in this folk tale reflect the difficulties women had in submitting to the norms and values of patriarchal order within their society.

    Full Text Available The article concerns itself with the figure of the teacher in Estonian society. We do not concentrate on the educational system as a whole, but on one specific and crucial element in this apparatus - the teacher. We begin by offering a brief historical overview of the conditions of pedagogues in the 20th century before moving on to describe the adoption of neo-liberal free market policies since the 1990s and the effects these policies had and still have on education. Our main concern is to understand the teacher as an actor in power relations; to achieve this understanding we have selected as our examples 1 surveillance techniques in school environment that have direct relations to the state and the market; and 2 the 2012 educational workers' strike that made it quite clear that the teachers have been fixed to a position of wage workers. The overall and more abstract aim of the paper is to think about the social role of the teacher in Estonia.

    Full Text Available A theoretical model was developed to model the fate of two common pharmaceutical residues: diclofenac and ibuprofen in eight Estonian seaside cities that discharge their wastewaters directly into the Baltic Sea. The consumption rates of the active ingredients of diclofenac and ibuprofen from 2006-2014 were analysed. A decrease of 19.9% for diclofenac consumption and an increase of 14.1% for ibuprofen were found. The fate of diclofenac and ibuprofen were modelled by considering the human metabolism removal rate for pharmaceuticals, the removal rate of diclofenac and ibuprofen in activated sludge wastewater treatment plants (WWTP and annual flow rates. An average decrease from 1 to 0.8 µg/l (decrease of 20% for diclofenac and an increase from 11.4 to 13.4 µg/l (increase of 14.9% for ibuprofen for the concentration in the effluents of the WWTP were modelled. The model gives us a good overview about the theoretical concentrations of pharmaceutical residues in the environment and is helpful for evaluating environmental impacts.

  18. History of experimental psychology from an Estonian perspective.

    2007-11-01

    A short review of the development of experimental psychology from an Estonian perspective is presented. The first rector after the reopening of the University of Dorpat (Tartu) in 1802, Georg Friedrich Parrot (1767-1852) was interested in optical phenomena which he attempted to explain by introducing the concept of unconscious inferences, anticipating a similar theory proposed by Herman von Helmholtz 20 years later. One of the next rectors, Alfred Wilhelm Volkmann (1800-1878) was regarded by Edwin Boring as one of the founding fathers of the experimental psychology. Georg Wilhelm Struve (1793-1864) played an essential part in solving the problem of personal equations. Arthur Joachim von Oettingen (1836-1920) developed a theory of music harmony, which stimulated his student Wilhelm Friedrich Ostwald (1853-1932) to study colour harmony. Emil Kraepelin (1856-1926), the founder of modern psychiatry, is by far the most important experimental psychologist who has worked in Estonia. His successor Wladimir von Tchisch (1855-1922), another student of Wilhelm Wundt, continued Kraepelin's work in experimental psychology. The lives of Wolfgang Köhler (1887-1967), who was born in Reval (Tallinn), and Oswald Külpe (1862-1915), who graduated from the University of Dorpat, extended the link between the history of experimental psychology and Estonia. Karl Gustav Girgensohn (1875-1925), the founder of the Dorpat School of the psychology of religion, stretched the use of experimental methods to the study of religious experience.

    The disaster that happened at the Chernobyl nuclear power station in 1986 caused a sharp rise in radioactive pollution over an extensive area in the region of the Baltic Sea. To estimate the distribution and the concentration of Cs-137 and Sr-90 in Estonian ecosystems, samples of mushrooms, mosses, lichens and the upper horizons of soil were gathered from 63 test sites during 1991. We were particularly interested in the amounts of radionuclides in mushrooms because these are used as food by people. Dangerously high radionuclide concentrations were found in mushrooms gathered in North-East Estonia. Heightened concentrations were registered here and there all over the territory of Estonia, especially in mushrooms gathered in Central and South-Western Estonia. The Cs-137 content in mushrooms depends on its content in other components of the ecosystems, first and foremost on the concentrations of radiocaesium in mosses and litter, which, therefore, can be used as indicators in prognostication the radioactive pollution of mushrooms in a certain region. As Cs-137 migrates between various ecosystem components, it is necessary to check the radioactivity of the forest products used for food for still a number of years to come. The Sr-90 level was low in all the ecosystem components examined. (author). 3 figs., 10 refs

    The objective of this study was to evaluate the efficacy of wellness trait genetic predictions in commercial herds of US Holstein cows from herds that do not contribute phenotypic information to the evaluation. Tissue samples for DNA extraction were collected from more than 3,400 randomly selected pregnant Holstein females in 11 herds and 2 age groups (69% nulliparous, 31% primiparous) approximately 30 to 60 d before their expected calving date. Lactation records from cows that calved between September 1, 2015, and December 31, 2015, were included in the analysis. Genomically enhanced predicted transmitting abilities for the wellness traits of retained placenta, metritis, ketosis, displaced abomasum, mastitis, and lameness were estimated by the Zoetis genetic evaluation and converted into standardized transmitting abilities. Mean reliabilities of the animals in the study ranged between 45 and 47% for each of the 6 traits. Animals were ranked by their standardized transmitting abilities within herd and age group then assigned to 1 of 4 groups of percentile-based genetic groups of equal size. Adverse health events, including retained placenta, metritis, ketosis, displaced abomasum, mastitis, and lameness, were collected from on-farm herd management software, and animal phenotype was coded as either healthy (0), diseased (1), or excluded for each of the 6 outcomes of interest. Statistical analysis was performed using a generalized linear mixed model with genetic group, age group, and lactation as fixed effects, whereas herd and animal nested within herd were set as random effects. Results of the analysis indicated that the wellness trait predictions were associated with differences in phenotypic disease incidence between the worst and best genetic groups. The difference between the worst and best genetic groups in recorded disease incidence was 2.9% for retained placenta, 10.8% for metritis, 1.1% for displaced abomasum, 1.7% for ketosis, 7.4% for mastitis, and 3

    Jersey x Holstein crossbreds (JxH; n = 76) were compared with pure Holsteins (n = 73) for 305-d milk, fat, and protein production; conception rate; days open; proportion of cows pregnant within fixed intervals postpartum; and body and udder measurements during first lactation. Cows were housed at 2 research locations of the University of Minnesota and calved from September 2003 to May 2005. The JxH were mated to Montbeliarde sires, and Holstein cows were mated to Holstein sires. Best Prediction was used to determine actual production (milk, fat, and protein) for 305-d lactations with adjustment for age at calving, and records less than 305 d were projected to 305 d. The JxH (274 kg) and pure Holsteins (277 kg) were not significantly different for fat production, but JxH had significantly less milk (7,147 vs. 7,705 kg) and protein (223 vs. 238 kg) production than pure Holsteins. The JxH had significantly fewer days open than pure Holsteins (127 vs. 150 d). Also, a significantly greater proportion of JxH were pregnant at 150 and 180 d postpartum than pure Holsteins (75 vs. 59% and 77 vs. 61%, respectively). The JxH had significantly less body weight (60 kg) at calving, but significantly greater body condition (2.80 vs. 2.71). Furthermore, JxH had significantly less udder clearance from the ground to the bottom of the udder than pure Holsteins (47.7 vs. 54.6 cm), and greater distance between front teats (15.8 vs. 14.0 cm) than pure Holsteins during first lactation.

    Full Text Available The aim of the study was to evaluate the genetic diversity in Holstein bulls population in Slovakia by the methods of pedigree analysis. The population was represented by the bulls with reserve of frozen semen doses in AI centers. Whole reference population consisted of 169 bulls born from 1997 to 2009. For calculation of diversity parameters the program Endog v.4.8 (Gutiérrez, Goyache, 2005 was used. An average maximal number of generations traced was 9.35, 3.06 complete generations and equivalent number of generations traced was 5.71. An average coefficient of inbreeding was 2.48%, individual increase in inbreeding was 0.53% and average relatedness was 2.72%. The 167 bulls from 169 were inbred (98.82%. An average number of offsprings per bull was 107.70 with maximal number 1,641 offsprings. The effective population size computed via individual increase in inbreeding was 94.50. The effective number of founders was 88, effective number of ancestors 31 and only 13 ancestors described 50% of diversity. From these results we can conclude that the diversity of Holstein bulls is reduced by more factors (inbreeding, high relatedness, bottlenecks. Obtained results point out the need to use new outbred bull lines for mating cows.

  4. Optimum body size of Holstein replacement heifers.

    Hoffman, P C

    1997-03-01

    Criteria that define optimum body size of replacement heifers are required by commercial dairy producers to evaluate replacement heifer management programs. Historically recommended body size criteria have been based on live BW measurements. Numerous research studies have observed a positive relationship between BW at first calving and first lactation milk yield, which has served as the impetus for using live BW to define body size of replacement heifers. Live BW is, however, not the only available measurement to define body size. Skeletal measurements such as wither height, length, and pelvic area have been demonstrated to be related to first lactation performance and (or) dystocia. Live BW measurements also do not define differences in body composition. Differences in body composition of replacement heifers at first calving are also related to key performance variables. An updated research data base is available for the modern Holstein genotype to incorporate measures of skeletal growth and body composition with BW when defining body size. These research projects also lend insight into the relative importance of measurements that define body size of replacement heifers. Incorporation of these measurements from current research into present BW recommendations should aid commercial dairy producers to better define replacement heifer growth and management practices. This article proposes enhancements in defining optimum body size and growth characteristics of Holstein replacement heifers.

    Full Text Available Women experience several problems during the childbirth process which always remain with them throughout their lives. These problems affect the health of the mother and the child, the emotional relationship between them, the sexual activity and the desire to have her next child in the future. This qualitative study is designed to explore the experiences of primiparous women about natural childbirth problems. This qualitative study is conducted on primiparous women who referred to the health center of Imam Javad in Zahedan. The sample selection is based on objective; the data are collected using semi-structured interviews with 18 primiparous mothers who had healthy natural childbirth. The data are collected through an interview that is done in the first visit within 72 hours after the childbirth, and the data are analyzed through content analysis. After analysis of the data, four themes associated with the problem of the first natural childbirth are extracted. The first is the fear and stress of the labor pain that most participants expressed as the major problem of natural childbirth. The second theme is lack of awareness and lack of information about the process of labor and the delivery room environment; this means that participants of this study are mostly unfamiliar with the process of labor and the delivery room environment and this leads to their fear and pain. The other two themes are the need for protection and support of the mothers by the midwives, their family and their friends. Based on the results of this study, the problems of human resources are stated as being more serious than the problems regarding the environment and modern equipment. This leads to the increase of attention of the midwives and other medical staff on psychological and spiritual needs of mothers and supporting them during the labor in addition to the physical health of the mother and the fetus. In this regard, childbirth classes are recommended in outlining the

    Full Text Available Aim of this study was to compare profitability of Burlina and Holstein Friesian cows in northern Italy. Cow’s profitability was calculated for each breed, with consideration of economic incentive programs and alternative milk pricing scenarios. The difference in annual profitability between Burlina and Holstein Friesian ranged from −€719 to −€274 per cow per year. In a low-input management level with a cow’s incentive payment and a specific cheese market strategy the low milk yield of Burlina can be compensate respect to Holstein Friesian.

    2002-01-01

    The article presents an overview of a research conducted in the Estonian Inst. of Economics and the Estonian Energy Research Inst. with the objectives to: analyse the dynamics of the main Estonian energy use indicators over the last 8-10 years with the background of general macroeconomics developments; compare these indicators with the respective energy indicators in the European Union Member States and Candidate Countries; evaluate Estonia's potential to catch up by the energy use efficiency (GDP energy intensity) of the average level of EU countries, modelling our possible development scenarios of GDP and TPES. The research results indicates several positive development tendencies (e.g. reduction of TPES and CO 2 emissions with the background of economic growth) in the Estonian energy sector, as well as convergence with the EU countries in terms of GDP energy intensity. Unfortunately, the model analysis results demonstrate that it takes a lot of time for Estonia to reach the current EU level - even under the most favourable GDP and TPES development conditions, 25-30 years. The primary reason is the very low level of our GDP per capita compared to the EU countries. (author)

    Full Text Available The article deals with the development in Russian-Estonian relations during the crises of 2007 and 2014, taking into consideration the balance between political and economic factors in the decision-making by Estonian government. A number of special aspects, trends and problems in trade and investment ties are detected. The aim of the study is to uncover key motivation behind the actions of both Russia and Estonia, to identify the drivers for economic and political development in the region, and to work out recommendations to adjust them. The questions put forward by the authors of this article could not be more topical at the time, when Russian economic situation is obviously getting worse and capital flight (to the neighboring EU Member States is likely to increase. The method of the study is comparative analysis of the impact on economic ties made by Russian-Estonian crisis of 2007 and the current international tension around Ukraine. The regional fossil fuel market and the possibilities of Gazprom involvement in its development are also analyzed. It is concluded that political motives are still important for Estonian decisionmaking, though they are balanced out by measures of business support (despite some of these measures being taken by the EU bodies. The role of political factor for the Russian side is increasing. It is acknowledged that there is a growing number of missed economic opportunities in the Russian Northwest.

    2011-01-01

    The concept of organisational culture (also referred to later as OC) is one of the approaches in modern organisational analysis exploring the values, attitudes and beliefs behind human behaviour in the workplace. OC as a social phenomenon is considered to be important for the sustainability of every organisation. In the service sector, OC may affect the nature and quality of the services provided. The aim of this paper is twofold: on the one hand, to highlight the patterns of OC in a hospital; and, on the other hand, to outline relationships between OC and patient satisfaction. The study was conducted in Tartu University Hospital, one of the most influential health care organisations in Estonia. This paper has original value by presenting an insight into organisational culture in the Estonian health care sector, and the findings of the study will expand knowledge of OC in the health care sector in general. The OC instrument applied in a quantitative cross-sectional study was earlier developed according to the Competing Values Framework (CVF). Data from 456 medical and non-medical professionals were analysed using non-parametric tests of descriptive statistics. A factor analysis was performed to assess the instrument's compatibility for analysing the OC pattern in the health care sector. The dominant culture type in all the groups investigated was the Internal Processes type, mainly followed by the Rational Goal type, while different cultural patterns were observed in professional groups. The factor analysis yielded a three-subscale solution. Clinics with high patient satisfaction did not score more than clinics with low patient satisfaction in terms of the Human Relations type. In future studies a random sample design and a multidisciplinary approach to OC research should be followed in order to further explore OC patterns in hospitals and their consequences for different aspects of hospital performance.

    2012-01-01

    As energy demand and prices continue to grow, oil shale might help mitigate the energy crisis—it can widely be found all over the world but so far has not been widely used. Estonia is unique in the world for producing a large majority of energy out of oil shale and has been set as an example in numerous papers covering oil shale deposits, technology etc. This paper is the first to analyse oil shale energy related workforce and provides scenario forecasts of the labour demand for the Estonian energy sector in 2010–2020. The contribution of the paper is twofold. First, the paper provides a valuable insight into oil shale energy related workforce, enabling to take into consideration the educational needs in countries where oil shale industry might be set up. Second, methodology-wise, the paper relates labour demand and supply to different scenarios of energy production capacities. The results illustrate problems related to aging of the workforce in energy production. If the existing trends continue in educational attainment in Estonia, there will be a serious shortage of high-skilled engineering and manufacturing specialists. Our method provides a simple yet reliable enough way to check for such problems early enough. - Highlights: ► This paper analyses oil shale energy related workforce and provides scenario forecasts. ► This is the first study to investigate the workforce related to oil shale energy production. ► The main workforce-related problem in the sector is ageing of the workforce. ► Workers immigrating to the sector during the Soviet times are at the retirement age. ► There will be a serious shortage of engineers for energy sector in the near future.

    To investigate primiparous women's preferences for care during a prolonged latent phase of labour. A qualitative study based on focus groups and individual interviews and analysed with inductive content analysis. Sixteen primiparous women with a prolonged latent phase of labour >18 hours were interviewed in five focus groups (n = 11) or individually (n = 5). One main category emerged "Beyond normality - a need of individual adapted guidance in order to understand and manage an extended latent phase of labour" which covers the women's preferences during the prolonged latent phase. Five categories were generated from the data: "A welcoming manner and not being rejected", "Individually adapted care", "Important information which prepares for reality and coping", "Participation and need for feedback" and "Staying nearby the labour ward or being admitted for midwifery support". Women with a prolonged latent phase of labour sought to use their own resources, but their needs for professional support increased as time passed. A welcoming attitude from an available midwife during the latent phase created a feeling of security, and personally adapted care was perceived positively. Women with a prolonged latent phase of labour preferred woman-centred care. Midwives play an important role in supporting these women. Women's need for midwifery-support increases as the time spent in latent phase increases. Copyright © 2015 Elsevier B.V. All rights reserved.

    Probiotics have been suggested to modify placental trophoblast inflammation, systemic inflammation, and blood pressure, all potentially interesting aspects of preeclampsia. The authors examined the association between consumption of milk-based probiotic products in pregnancy and development of preeclampsia and its subtypes. The study was performed in the Norwegian Mother and Child Cohort Study by using a prospective design in 33,399 primiparous women in the years 2002–2008. The intake of milk-based products containing probiotic lactobacilli was estimated from a self-reported food frequency questionnaire. Preeclampsia diagnoses were obtained from the Norwegian Medical Birth Registry. Intake of probiotic milk products was associated with reduced risk of preeclampsia. The association was most prominent in severe preeclampsia (adjusted odds ratio (OR) = 0.79, 95% confidence interval (CI): 0.66, 0.96). With probiotic intakes divided into categories representing no, monthly, weekly, or daily intake, a lower risk for preeclampsia (all subtypes) was observed for daily probiotic intake (OR = 0.80, 95% CI: 0.66, 0.96). Lower risks for severe preeclampsia were observed for weekly (OR = 0.75, 95% CI: 0.57, 0.98) and daily (OR = 0.61, 95% CI: 0.43, 0.89) intakes. These results suggest that regular consumption of milk-based probiotics could be associated with lower risk of preeclampsia in primiparous women. PMID:21821542

    Full Text Available Introduction: The integration of reflexology as one of the non-pharmacological pain relief methods in to midwifery care has become more common in recent years. The aim of this study was to determine the effect of reflexology on pain intensity and the duration of labor in primiparous.Materials and Methods: This clinical trial study was carried out on 80 primiparous women with low risk pregnancy that referring to Karaj hospitals (Iran then randomized in two groups, intervention group which received reflexology for 40 minutes and control group. Severity of labor pain was shown by visual analogue scale (McGill questionnaire, before, half, one and two hours after intervention. Moreover, the duration of labor was determined for both groups.Results: Severity of labor pain before and immediately after intervention foot reflexology did not vary between case and control groups (p>0.05. But half, one and two hours after it, severity of labor pain in the intervention group was lower than the control group (P<0.001. Duration of labor in the intervention group significantly was lower than the control group (P<0.001.Conclusion: Reflexology can lead to decrease in labor pain as well as duration of labor. Therefore, we can use this non-invasive technique to decrease the labor pain and encourage mothers to normal vaginal delivery that is one of the aims of midwifery

    Results from 4 studies were combined (representing a total of 500 lactations) to investigate the relationships between metabolic parameters and fertility in dairy cows. Information was collected on blood metabolic traits and body condition score at 1 to 2 wk prepartum and at 2, 4, and 7 wk postpartum. Fertility traits were days to commencement of luteal activity, days to first service, days to conception, and failure to conceive. Primiparous and multiparous cows were considered separately. Initial linear regression analyses were used to determine relationships among fertility, metabolic, and endocrine traits at each time point. All metabolic and endocrine traits significantly related to fertility were included in stepwise multiple regression analyses alone (model 1), including peak milk yield and interval to commencement of luteal activity (model 2), and with the further addition of dietary group (model 3). In multiparous cows, extended calving to conception intervals were associated prepartum with greater concentrations of leptin and lesser concentrations of nonesterified fatty acids and urea, and postpartum with reduced insulin-like growth factor-I at 2 wk, greater urea at 7 wk, and greater peak milk yield. In primiparous cows, extended calving to conception intervals were associated with more body condition and more urea prepartum, elevated urea postpartum, and more body condition loss by 7 wk. In conclusion, some metabolic measurements were associated with poorer fertility outcomes. Relationships between fertility and metabolic and endocrine traits varied both according to the lactation number of the cow and with the time relative to calving.

    Full Text Available This article attempts to explain the relationships between journalists, politics and the state from the perspective of collective autonomy, that of the professional organization of journalists. The case of Estonian Journalists’ Union demonstrates the complexity and historical contingency of professional autonomy of journalism. The development of the Estonian journalists’ organization occurred as a sequence of transformations from the Estonian Journalists’ Association to the Estonian Journalists’ Union to the Soviet type journalists’ union, and lastly to an independent trade union. This sequence was disrupted by several fatal breakdowns that changed not only the character of the association, but also professional values, the whole occupational ideology and the conditions of the existence of journalism as a profession in Estonia.

    Full Text Available This article begins by examining points of intersection between two professional theatres, ”Estonia” and ”Vanemuine” (both established in 1906, their young directors – Karl Menning, Paul Pinna, Theodor Altermann, and Karl Jungholz, and the literary movement Young Estonia. Subsequently, we will consider Young Estonia’s theatrical ideals and the influence of these ideas on later Estonian theatrical life. Since not much information has survived regarding direct personal contacts between ”movers and shakers” in the theatre world and Young Estonians, the main focus here shall be on indirect creative connections and influences. One such context is education: like the Young Estonians, theatre activists of the younger generation aspired to place themselves on the larger map of European culture. Thus, their artistic beliefs and goals shall be examined in relation to those of Young Estonians’ quest for modern culture. Pinna, Altermann, Menning, Jungholz, and others went on study tours to Germany and France, where they were energized and inspired by innovative German and Russian theatres, by naturalistic staging, and by psychological realism, both in acting and in performance style. Among their models were A. Antoine’s Théâtre- Libre in Paris, K. Stanislavski’s Art Theatre in Moscow, O. Brahm’s Lessing-Theater, and M. Reinhardt’s Deutsches Theater in Berlin. These models were likewise known to the Young Estonians, but if theatre activists oriented themselves more fundamentally to German naturalist and realist dramatic art, Young Estonians were more taken with ”theatrical theatre” with its symbolist and impressionist influences. The Young Estonians attended performances at both theatres, ”Vanemuine” and ”Estonia”, and wrote numerous theatre reviews. Yet in the Young Estonia albums (yearbooks and in the magazine Young Estonia, theatre topics have a relatively modest representation. Young Estonians did not have direct

    Estonian oil shale is one of the oldest and richest oil shales in the world. The deposits occur in the Middle-Ordovician strata having a total thickness of 2.2 meters. The ultimate composition of the kerogen varied within the following limits: carbon 76.5 to 76.7 percent, hydrogen 9.1 to 9.2 percent, nitrogen 0.2 to 0.4 percent, sulfur 1.6 to 2.2 percent, chlorine 0.5 to 0.7 percent, and oxygen (by difference) 11.2 to 12.2 percent. The composition of kukersite kerogen corresponds nearly to the empirical formula (C/sub 8/H/sub 11/O)n. One of the most significant differences between kukersite, coal, and lignite is the amount of alkali-soluble substances present. Kukersite has almost no humic acids. Samples of kukersite were brominated and chlorinated. The halogenated shales showed a solubility in absolute alcohol of 26 percent compared to only 0.31 percent for untreated shale. Enriched shale (4.5 percent ash) did not react with chlorine as much as did raw shale. Apparently the mineral matter acted catalytically during chlorination. The amount of soluble extract obtained by solvent treatment of kukersite ranged from 0.22 percent with chloroform to 2.20 percent with tetrachloroethane. Heat was the most effective agent for the depolymerization of kukersite kerogen. The percentage loss of weight due to drying in air was much less than in the presence of carbon dioxide. The results indicated that on drying in air, the powdered shale loses water and a volatile substance, probably the oxides of carbon, up to 80/sup 0/C. Carbon dioxide was also found to be present in the gases eliminated at the temperature of initial decomposition. Pulverized shale, heated for 6 hours at 220/sup 0/C, lost 2.6 percent of its weight; its solubility in carbon disulfide was 2.11 percent. Kukersite kerogen was formed from compounds that were resistent to bacteriological decomposition, such as waxes and resins, plus decomposition products of proteins, cellulose, and putrefaction products of

    2006-10-01

    This paper presents the results of the distribution of trace elements in Estonian mires. Sixty four mires, representative of the different landscape units, were analyzed for the content of 16 trace elements (Cr, Mn, Ni, Cu, Zn, and Pb using AAS; Cd by GF-AAS; Hg by the cold vapour method; and V, Co, As, Sr, Mo, Th, and U by XRF) as well as other peat characteristics (peat type, degree of humification, pH and ash content). The results of the research show that concentrations of trace elements in peat are generally low: V 3.8 ± 0.6, Cr 3.1 ± 0.2, Mn 35.1 ± 2.7, Co 0.50 ± 0.05, Ni 3.7 ± 0.2, Cu 4.4 ± 0.3, Zn 10.0 ± 0.7, As 2.4 ± 0.3, Sr 21.9 ± 0.9, Mo 1.2 ± 0.2, Cd 0.12 ± 0.01, Hg 0.05 ± 0.01, Pb 3.3 ± 0.2, Th 0.47 ± 0.05, U 1.3 ± 0.2 μg g - 1 and S 0.25 ± 0.02%. Statistical analyses on these large database showed that Co has the highest positive correlations with many elements and ash content. As, Ni, Mo, ash content and pH are also significantly correlated. The lowest abundance of most trace elements was recorded in mires fed only by precipitation (ombrotrophic), and the highest in mires fed by groundwater and springs (minerotrophic), which are situated in the flood plains of river valleys. Concentrations usually differ between the superficial, middle and bottom peat layers, but the significance decreases depending on the type of mire in the following order: transitional mires - raised bogs - fens. Differences among mire types are highest for the superficial but not significant for the basal peat layers. The use of peat with high concentrations of trace elements in agriculture, horticulture, as fuel, for water purification etc., may pose a risk for humans: via the food chain, through inhalation, drinking water etc.

    To quantify PH prevalence in primiparous adolescents; define predictive factors for the occurrence of PH and its impact on newborns. We followed 29 primiparous adolescents from the prenatal period through the 12th week of the puerperium, with a mean of sixteen years of age, served at the Outpatient Facility for Adolescents of Maternidade Escola Assis Chateaubriand (MEAC) of Universidade Federal do Ceará (Fortaleza, Brazil). The pregnant adolescents were divided into two groups, that is, those who remained normotensive (Group I) and those who developed PH (Group II). The variables investigated in the assessment of the value of predictability for the development of PH were anthropometric measures, socioeconomic aspects, smoking habit, inheritance for SAH (father/mother), prenatal tests requested in the first prenatal care visit in addition to microalbuminuria and ambulatory blood pressure monitoring (ABPM) in the 28th week of gestation. The pregnant adolescents were followed up at delivery and late puerperium (12th week after the puerperium). The newborns to the mothers included in our study were assessed at birth according to the Apgar score and the Capurro method, for weight, height and perinatal hypoxia. The prevalence of PH was 51.7%. Inheritance for SAH presented the highest predictive value for PH with an odds ratio of 10.99. Diastolic arterial pressure equal to or above 70 mmHg at the gestational age of 35 weeks was statistically significant as a predictive value for PH. At ABPM we found a predictive value for PH: diastolic pressure load during alertness, diastolic and systolic pressure load during night sleep, pressure variability and maximum diastolic pressure during sleep. Specifically a maximum diastolic arterial pressure (DAP) at ABPM during the period of night sleep (3)64 mmHg presented an odds ratio of 6 for PH with a sensitivity of 80% and a specificity of 60% for the development of PH.

    Acute Escherichia coli mastitis is one of the major sources of economic loss in the dairy industry due to reduced milk production, treatment costs, discarded milk, and occasional fatal disease. Nonsteroidal anti-inflammatory drugs (NSAIDs) are frequently used as adjunctive therapy to antibiotics. The objective of the current study was to evaluate the effect of carprofen treatment following infusion of Escherichia coli into the mammary glands of primiparous cows during the periparturient period. Severity of mastitis was scored based on the average milk production in the uninfected quarters on d +2 postinoculation and a clinical severity score. Carprofen was administered intravenously at 9 h postchallenge, when clinical signs of mastitis appeared. In previous work, efficacy of NSAIDs was mainly evaluated using clinical symptoms. In the present study, the effect of carprofen on innate immune response was also assessed by quantification of inflammatory mediators. All primiparous cows reacted as moderate responders throughout the experimental period. Primiparous cows were intramammarily inoculated with 1 x 10(4) cfu of E. coli P4:O32 in 2 left quarters. Analysis of blood and milk parameters, including IL-8, complement component C5a, lipopolysaccharide-binding protein (LBP), soluble CD14, prostaglandin E2, and thromboxane B2 was performed from d 0 to d +6 relative to intramammary inoculation. Rectal temperature in carprofen-treated animals was lower than in control animals at 3 and 6 h posttreatment. Treatment also restored the decreased reticulorumen motility that occurs during E. coli mastitis to preinfection levels faster than in control animals. Carprofen treatment resulted in an earlier normalization of the clinical severity score. Eicosanoid (prostaglandin E2 and thromboxane B2) production in milk tended to be inhibited by carprofen. No significant differences in the kinetic patterns of somatic cell count, IL-8, complement component C5a, LBP, and soluble CD14 were

    Effects of supplemental degradable (DIP) and undegradable (UIP) intake protein on forage intake, BW change, body condition score (BCS), postpartum interval to first estrus, conception rate, milk production and composition, serum metabolites and metabolic hormones, and calf gain were determined using 36 primiparous Gelbvieh x Angus rotationally crossed beef cows. On d 3 postpartum, cows (average initial BW = 495 +/- 10 kg and BCS = 5.5 +/- 0.1) were randomly assigned to one of three dietary supplements (12 cows/treatment). Date of parturition was evenly distributed across treatment (average span of calving date among treatments = 2.4 +/- 2.5 d). Individually fed (d 3 through 120 postpartum) dietary supplements were 0.82 kg of corn and 0.23 kg of soybean meal per day (DIP), the DIP + 0.12 kg of blood meal and 0.13 kg of corn gluten meal per day (DIP + UIP), and 0.82 kg of corn, 0.07 kg of blood meal, and 0.08 kg of corn gluten meal per day in an isonitrogenous replacement of soybean meal (UIP IsoN). Cows had ad libitum access to native grass hay (8.5% CP) and trace-mineralized salt. Total OM intake was greater (P = 0.06) for DIP + UIP than UIP IsoN cows. At 30 d postpartum, DIP + UIP cows produced more milk than UIP IsoN, with DIP being intermediate; however, at 60 d postpartum, DIP + UIP and DIP cows were not different, but both had greater milk production than UIP IsoN (treatment x day interaction; P = 0.08). A treatment x day interaction (P = 0.06) for BCS resulted from DIP + UIP cows having the greatest BCS at 60, 90, and 120 d d postpartum and DIP having greater BCS than UIP IsoN cows only on d 60 postpartum. Serum insulin concentrations were highest (treatment x day interaction; P = 0.09) for DIP + UIP cows at 30 d postpartum but did not differ among treatment thereafter. Serum insulin-like growth factor-binding protein (IGFBP)-2 (34 kDa) and -3 (40 and 44 kDa) were greatest (P calf weaning weights were unaffected (P = 0.35, 0.42, and 0.64, respectively) by

    Parental stress, optimism, and health-promoting behaviors (HPBs) are important predictors of the quality of life (QoL) of mothers. However, it is unclear how strongly these predictors affect the QoL of mothers. It is also unclear if the impact of these predictors on QoL differs between primiparous and multiparous mothers. In this study, we defined primiparous as "bearing young for the first time" and multiparous as "having experienced one or more previous childbirths." The first objective of this study was to examine the relative effect of parental stress, optimism, and HPBs on the QoL of mothers. The second objective was to investigate if the effect of these predictors differed between primiparous and multiparous mothers. One hundred ninety-four Australian mothers (n = 87, 44.8% primiparous mothers) participated in an online survey that included the Parental Stress Scale, the Health-Promoting Lifestyle Profile II, the Revised Life Orientation Test, and the Quality of Life Enjoyment and Satisfaction Questionnaire. All predictors (parental stress, optimism, and HPBs) significantly affected the QoL of mothers; higher levels of optimism, greater use of HPBs, and lower parental stress were associated with higher levels of QoL for all mothers. Parity did not affect the relationships. This study sheds light on the nature and unique effect of parental stress, optimism, and HPBs on the QoL of mothers.

    It is to compare the levels of fasting glucose and insulin as well as insulin resistance in grand multiparas with primiparity and nulliparity. Fasting blood samples were collected from 100 non-pregnant ladies as control group, 100 primiparity pregnant women and 100 grand multiparity pregnant women. Glucose (FBS) and insulin (FSI) concentrations were measured by Hitachi 912 full automated Chemistry Analyzer (Roche Diagnostics, Germany) as manufacturer procedure. Insulin resistance was calculated following the formula: FBG (mg dL-1)×FSI (μU mL-1)/405. This study found a significant reduction in glucose level in primiparity when compared to control group but it was increased significantly in multiparity comparing to primiparity and control. Insulin level showed significant high concentrations in pregnant women and increased significantly in grand multiparas comparing to primiparas and controls. As a result of that, HOMA-IR was increased significantly by increasing of parity. Also, there was a significant increase in fasting insulin and a decrease in insulin sensitivity with parity with association to age and obesity. Grand multiparity is associated with an increased risk of subsequent clinical insulin resistance (HOMA-IR).

    Bacterial populations of teat skin are associated with risk of intramammary infection and may be influenced by anatomical characteristics of teats. The objective of this study was to evaluate associations of selected anatomical characteristics of teats with bacterial counts of teat skin of cows exposed to different types of bedding. Primarily primiparous Holstein cows (n = 128) were randomly allocated to 4 pens within a single barn. Each pen contained 1 type of bedding [new sand (NES), recycled sand (RS), deep-bedded manure solids (DBMS), and shallow-bedded manure solids over foam core mattresses (SBMS)]. During a single farm visit udders (n = 112) were scored for hygiene and 1 front (n = 112) and 1 rear teat (n = 111) of each enrolled cow were scored for hyperkeratosis (HK). Teat length, teat barrel diameter, and teat apex diameter were measured and teat skin swabs were systematically collected for microbiological analysis. Linear type evaluation data for udders of each cow were retrieved for each cow. Teat position (front or rear) was associated with occurrence of clinical mastitis during the 12 mo before the farm visit and more cases occurred in front quarters. The proportion of udders that were classified as clean (score 1 or 2) was 68, 82, 54, and 95% for cows housed in pens containing NES, RS, SBMS, and DBMS, respectively. No association was found between HK score and teat position and no association was found between HK score and teat skin bacterial count. Bacterial counts of teat skin swabs from front teats of cows in pens containing RS and SBMS were significantly less than those of rear teats of cows in pens containing DBMS or NES. Teat skin bacterial counts were significantly greater for swabs obtained from teats of cows with udder hygiene scores of 3 and 4 as compared with swabs obtained from cows with cleaner udders. Of all udder conformation traits evaluated, only narrower rear teat placement was positively associated with bacterial counts on teat skin

    Full Text Available Background: Pregnant women with insecure attachment style are at high risk of psychiatric disorders. Since emotions are the first coordinators of attachment behavior, emotion regulation training can alter maternal attachment style. In this study, we aimed to evaluate the effects of emotion regulation training on the attachment styles of primiparous pregnant women with insecure attachment style. Aim: This study aimed to evaluate the effects of training programs on the headache of patients after spinal anesthesia. Method: This randomized, clinical trial on 40 primiparous pregnant women with age range of 30-34 years, who were referred to healthcare centers of Mashhad, Iran, during 2014. The data collection instrument was Revised Adult Attachment Scale (RAAS. The participants were assigned to intervention and control groups. A training program was implemented on emotion regulation based on dialectical behavior therapy (DBT for the intervention group. After delivery, RAAS was completed by the mothers again. The control group only received the routine care. To analyze the data, Chi-square and independent t-test were run using SPSS, version 15. Results: Mean ages of the mothers in the intervention and control groups were 26.9±4.04 and 27.5±3.5 years, respectively. According to the results of independent t-test, the difference between the groups was non-significant (P=0.77. The groups were analogous in terms of attachment style pre-intervention. After the intervention, independent t-test did not reflect any significant differences between the groups regarding avoidant (P=0.37 and anxious (P=0.11 attachment styles. However, mean score for secure attachment style was significantly enhanced (P=0.01. Implications for Practice: Our findings revealed that implementation of emotion regulation training increased secure attachment scores. Thus, implementing emotion regulation training program is recommended as part of a program for pre-natal care in healthcare

METHODS: This cohort study was conducted in 165 primiparous women aged 18-35 years referring to the healthcare centers in Tehran, Iran, during 2013-2014. The participants were chosen through stratified random sampling and divided into two groups of low physical activity (n=68 and moderate or high physical activity (n=97. Both groups completed the International Physical Activity Questionnaire (IPAQ during weeks 28 and 34 and Depression Anxiety Stress Scale (DASS at the end of the sixth postpartum week. For each sub-scale, the minimum and maximum possible scores of this scale are 0 and 21, respectively. FINDINGS: Mean total scores of stress, anxiety, and depression of the low physical activity group were 9.85±5.74, 5.61±5.11, and 6.23±5.77, respectively, while for the moderate or high physical activity group they were 9.88±5.84, 5.72±5.03, and 6.51±5.70, respectively. In addition, no significant difference was observed between the two groups in terms of mean total score of stress (p=0.969, anxiety (p=0.585, and depression (p=0.396 at the end of the sixth postpartum week. Moreover, no statistically significant relationship was observed between the level of physical activity during pregnancy and postpartum mood. CONCLUSION: According to our results, physical activity during pregnancy is not associated with postpartum stress, anxiety, and depression.

    the health and survival of newborns depend on high levels of attention and care from caregivers. The growth and development of some infants are unhealthy because of their mother's or caregiver's lack of knowledge or the use of inappropriate or traditional child-rearing practices that may be harmful. to develop a newborn care educational programme and evaluate its impact on infant and maternal health in Nepal. a randomised controlled trial. one hundred and forty-three mothers were randomly assigned to the intervention (n=69) and control (n=74) groups. Eligible participants were primiparous mothers who had given birth to a single, full-term, healthy infant, and were without a history of obstetric, medical, or psychological problems. prior to being discharged from the postnatal unit, the intervention group received our structured newborn care education programme, which consisted of one-on-one educational sessions lasting 10-15minutes each and one postpartum follow-up telephone support within two weeks after discharge, in addition to the hospital's routine general newborn care education. The control group received only the regular general newborn care education. Outcomes were measured by using Newborn care Knowledge Questionnaires, Karitane Parenting Confidence Scale, State-Trait Anxiety Inventory for Adults and infant health and care status. the number of mothers attending the health centre due to the sickness of their babies was significantly decreased in the intervention group compared to the control group. Moreover, the intervention group had significant increases in newborn care knowledge and confidence, and decreases in anxiety, compared with the control group. the structured newborn care education programme enhanced the infant and mother health. Moreover, it increased maternal knowledge of newborn care and maternal confidence; and reduced anxiety in primiparous mothers. Thus, this educational programme could be integrated into routine educational programs to

    Full Text Available Background and aim: Postpartum period is often associated with decreased marital satisfaction in couples. The present study aimed to investigate factors contributing to marital satisfaction in primiparous women during postpartum period. Methods: This correlational study was performed on 104 primiparous women who referred to health care centers, Mashhad, Iran in 2013, 8 weeks after delivery, to receive health care services. Convenient sampling was the method of choice, and data collection tools included Nathan H. Azarin marital satisfaction questionnaire, stress, anxiety and depression scales (DASS-21, and demographic and fertility-related questionnaire. Data were analyzed using SPSS version 16, and statistical tests of Kruskal-Wallis and Pearson correlation coefficient. Results: The mean score of women’s marital satisfaction was 65.37±17.4. There was a significant inverse correlation between duration of marriage (r₌-0.246, P=0.01, women’s age (r₌-0.203, P=0.03 and husband’s age (r₌-0.219, P=0.02 with marital satisfaction. Also a significant relationship was seen between the onset of sexual intercourse after childbirth (r₌0.268, P=0.006 and frequency of intercourse per week (P=0.001 with marital satisfaction. Additionally, there was a significant inverse correlation between depression (r₌-0.414, P=0.001, anxiety (r₌-0.27, P=0.004, and stress (r₌-0.203, P=0.03 with marital satisfaction. Conclusion: The age of women and their spouses, the duration of marriage, the onset and frequency of sexual intercourse after delivery, stress, depression, and anxiety are factors contributing to females’ marital satisfaction in postpartum period. As marital satisfaction affects the health of couples and families, it is therefore recommended to increase females’ marital satisfaction during the postpartum period through recognizing the related factors and planning appropriate interventions.

    Full Text Available This paper focuses on the meanings assigned to Tatar language among the Tatar diaspora in Estonia. According to interviews with Estonian Tatars as well as descriptions of field material from Tatarstan, language is an important aspect of Tatar ethnic identity. This paper will track common discourses about the Tatar language and the way it is connected to Tatar ethnic identity. Issues concerning Tatar language are used to demonstrate various ways of enacting Tatarness in Estonia. It is shown that Estonian Tatars worry about the vitality and purity of Tatar language, but for some, marginalization of dialects is also an issue. People categorized with the same identity labels by self and others can experience and enact their Tatarness in a variety of different ways.

    This case study of the Estonian Genome Project (EGP) analyses the Estonian policy decision to construct a national human gene bank. Drawing upon qualitative data from newspaper articles and public policy documents, it focuses on how proponents use discourse to link the EGP to the broader political goal of securing Estonia's position within the Western/European scientific and cultural space. This dominant narrative is then situated within the analytical notion of the "brand state", which raises potentially negative political consequences for this type of market-driven genomic research. Considered against the increasing number of countries engaging in gene bank and/or gene database projects, this analysis of Estonia elucidates issues that cross national boundaries, while also illuminating factors specific to this small, post-Soviet state as it enters the global biocybernetic economy.

Layoffs have increased the number of unemployed; some of those who have lost employment opt for social assistance benefits, but some others decide to become entrepreneurs. Many enterprising people in Estonia have set up a family enterprise, mainly in the sphere of services, agriculture and tourism. The Estonian entrepreneurship policy supports enterprising people and approves of entrepreneurship as a promoter of national economic development. One of the most positive qualities of family enterprises is their short decision-making chain, which ensures rapid implementation of the strategy.

  14. Is Estonian oil shale beneficial in the future?

    1998-01-01

    Oil shale mining production reached its maximum level of 31.35·10 6 tonnes per year in 1980. After the eighties there was a steady decline in mining. The first scientific prognoses of the inescapable decrease in oil shale mining were published in 1988. According to this, the Estonian oil shale industry would vanish in the third decade of the next century. From the beginning of the nineties, the consumption and export of electricity have dropped in Estonia. The minimum level of oil shale mining was 13.5·10 6 tonnes per year. This occurred in 1994/1995. Some increase in consumption of electric power and oil shale began at the end of 1995. Oil shale processing began to increase gradually in 1993. Oil shale is the most important fuel in Estonia today. In 1997, oil shale provided 76% of Estonia's primary energy supply and accounted for 57% of its economic value. Oil shale is the cheapest fuel in Estonia. Nowadays, oil shale provides an essential part of the fuel supply in Estonia because it is considerably cheaper than other fuels. Oil shale costs EEK 12.16 per G J. At the same time, coal costs EEK 23.41 per G J and peat costs EEK 14.80 per G J (year 1997). There are three important customers of oil shale: the electric power company Eesti Energia, the oil processing company Kiviter and the factory Kunda Nordic Cement. In 1995, the power company utilised 81% of the oil shale mass and 77% of its heating value. The state energy policy inhibits increases in the oil shale price even though the mining infrastructure is decaying. Government price policies subside oil shale processing. The energy of oil shale processing is 1.9 times cheaper than the heating value of raw oil shale for power stations. It could be considered as a state subsidisation of oil and cement export at the expense of electricity. The subsidy assigned to oil processing was of EEK 124·10 6 and to the cement industry of EEK 8.4·10 6 in year 1997 (based on heating value). State regulation of prices and

    We present data from an observational cohort study on human immunodeficiency virus (HIV) prevention and control measures in prisons in Estonia to assess the potential for HIV transmission in this setting. HIV testing and retesting data from the Estonian prison health department were used to estimate HIV prevalence and incidence in prison. Since 2002, voluntary HIV counselling and testing has routinely been offered to all prisoners and has been part of the new prisoners health check. At the end of 2012, there were 3,289 prisoners in Estonia, including 170 women: 28.5% were drug users and 15.6% were infected with HIV. Of the HIV-positive inmates, 8.3% were newly diagnosed on prison entry. In 2012, 4,387 HIV tests (including retests) were performed in Estonian prisons. Among 1,756 initially HIV-negative prisoners who were in prison for more than one year and therefore tested for HIV twice within 12 months (at entry and annual testing), one new HIV infection was detected, an incidence of 0.067 per 100 person-years (95% confidence interval (CI): 0.025–5.572). This analysis indicates low risk of HIV transmission in Estonian prisons. Implementation of HIV management interventions could impact positively on the health of prisoners and the communities to which they return.

    Despite diagnostic and therapeutic advancements, the burden of cancer is still increasing worldwide. Toxicity of current chemotherapeutics to normal cells and their resistance to tumor cells highlights the urgent need for new drugs with minimal adverse side effects. The use of natural anticancer agents has entered into the area of cancer research and increased efforts are being made to isolate bioactive products from medicinal plants. To lead the search for plants with potential cytotoxic activity, ethnopharmacological knowledge can give a great contribution. Therefore, the attention of this review is devoted to the natural remedies traditionally used for the cancer treatment by Estonian people over a period of almost 150 years. Two massive databases, the first one stored in the Estonian Folklore Archives and the second one in the electronic database HERBA ( http://herba.folklore.ee/ ), containing altogether more than 30 000 ethnomedicinal texts were systematically reviewed to compile data about the Estonian folk traditional experiences on natural anticancer remedies. As a result, 44 different plants with potential anticancer properties were elicited, 5 of which [Angelica sylvestris L. (Apiaceae), Anthemis tinctoria L. (Asteraceae), Pinus sylvestris L. (Pinaceae), Sorbus aucuparia L. (Rosaceae), and Prunus padus L. (Rosaceae)] have not been previously described with respect to their tumoricidal activities in the scientific literature, suggesting thus the potential herbal materials for further investigations of natural anticancer compounds.

    To compare smoking behaviour, attitudes and opinions towards smoking and smoking cessation among Estonian and Finnish physicians. A cross-sectional postal survey using a self-administered questionnaire was carried out among 2,480 Estonian and 2,075 Finnish physicians. Daily smoking prevalence was higher among Estonian physicians than among their Finnish counterparts in both male (18.6% and 6.7%) and female (6.6% and 3.6%). Compared to Estonia, physicians in Finland more often agreed that smoking is very harmful to their health, that trying to convince people to stop smoking is their responsibility and that smoking prevention should be part of the normal and special training of health professionals. In both countries, non-smoking physicians held more unfavourable attitudes towards smoking than those who were smoking. Physicians' own smoking patterns and quitting behaviour are important because physicians serve as models for their patients and play a key role in the reinforcement of smoke-free health facilities. These results remain a challenge to medical educators, especially in Estonia. Estonia needs to improve medical education in terms of motivating physicians to ask about the smoking patterns of their patients and of training medical students and resident physicians to counsel their patients to stop smoking.

    The report describes the development and summarizes the results of the project Cancer incidence and thyroid disease among Estonian Chernobyl clean-up workers. One of the goals of the report is to give research protocols and questionnaires for researchers involved in other studies. Eight previously published articles are also included summarizing the results. The development of the collaboration work of the project is described in the introduction of the report. Epidemiological methods are described in an article complemented by the protocol and English version of the questionnaire administered to all cleanup workers, as well as the data collection form of the thyroid study. The results from biological biodosimetry using both glycophorin A and FISH methods have shown that the radiation doses received by the Chernobyl cleanup workers were relatively low. Thyroid nodularity was not associated with any radiation exposure characteristic in the thyroid screening study. Estonian Chernobyl cleanup workers were followed up for cancer incidence through the Estonian Cancer Registry. No cases of leukemia or thyroid cancer were observed by the end of 1993. It is too early to observe possible effect on other types of cancer. However, mortality from suicides was increased compared with general population. Further follow-up and the extension to other Baltic countries in the future will undoubtedly strengthen the study. There are also plans for future projects covering areas from psychosocial factors to radiation biology

    Since 1988 the Land of Schleswig Holstein has been going new ways in its energy policy. Its declared aims are energy saving in heat and electricity supply, efficient energy utilisation, a greater utilisation of renewable energy resources, and, of principal importance, the phase-out of nuclear energy. As the legislative competence of the Laender is very restricted in matters relating to energy, the new policy has primarily been designed as a means of demonstrating by way of example that there actually are considerable potentials for saving energy and that they can be exploited. The present report gives an overview of the results of Schleswig Holstein`s energy policy of the last seven years. (orig./RHM) [Deutsch] Seit 1988 geht das Land Schleswig-Holstein energiepolitisch neue Wege. Das erklaerte Ziel: Energieeinsparung im Waerme- und Strombereich, rationelle Energieverwendung, staerkere Nutzung erneuerbarer Energien. Und grundsaetzlich: Ausstieg aus der Kernenergie. Da die Bundeslaender nur ueber eine sehr eingeschraenkte Gesetzgebungskompetenz im Energiebereich verfuegen, zielte die neue Energiepolitik zunaechst darauf ab, durch Foerderprogramme beispielhaft zu zeigen, dass tatsaechlich erhebliche Einsparpotentiale bestehen und auch umsetzbar sind. Der Bericht gibt einen Ueberblick ueber die Ergebnisse der Energiepolitik der letzten sieben Jahre in Schleswig-Holstein. (orig./RHM)

    The objective of this study was to estimate the effects of clinical mastitis (CM) cases due to different pathogens on milk yield in Holstein cows. The first 3 CM cases in a cow's lactation were modeled. Eight categories of pathogens were included: Streptococcus spp.; Staphylococcus aureus; coagulase-negative staphylococci (CNS); Escherichia coli; Klebsiella spp.; cases with CM signs but no bacterial growth (above the level detectable by our microbiological procedures) observed in the culture sample, and cases with contamination (≥ 3 pathogens in the sample); other pathogens that may be treated with antibiotics (included Citrobacter, Corynebacterium bovis, Enterobacter, Enterococcus, Pasteurella, Pseudomonas; "other treatable"); and other pathogens not successfully treated with antibiotics (Trueperella pyogenes, Mycoplasma, Prototheca, yeasts; "other not treatable"). Data from 38,276 lactations in cows from 5 New York State dairy herds, collected from 2003-2004 until 2011, were analyzed. Mixed models with an autoregressive correlation structure (to account for correlation among the repeated measures of milk yield within a lactation) were estimated. Primiparous (lactation 1) and multiparous (lactations 2 and 3) cows were analyzed separately, as the shapes of their lactation curves differed. Primiparas were followed for up to 48 wk of lactation and multiparas for up to 44 wk. Fixed effects included parity, calving season, week of lactation, CM (type, case number, and timing of CM in relation to milk production cycle), and other diseases (milk fever, retained placenta, metritis, ketosis, displaced abomasum). Herd was modeled as a random effect. Clinical mastitis was more common in multiparas than in primiparas. In primiparas, Streptococcus spp. occurred most frequently as the first case. In multiparas, E. coli was most common as the first case. In subsequent cases, CM cases with no specific growth or contamination were most common in both parity groups. The hazard of

We further compute the optical conductivity of the system at the Dirac point and at finite doping within the Kubo formula. We argue that the effects due to Holstein phonons are negligible and that the Boltzmann approach, which does not include inter-band transitions and can thus not treat optical phonons due to their high energy of ℎω 0 ∼ 0.1-0.2 eV, remains valid

    The fertility of lactating Holstein cows is severely reduced during periods of heat stress. Despite this reduction in fertility, however, some inseminations conducted during heat stress result in successful pregnancies from which heifer calves are born. Many of these heifer calves are retained and raised to enter the milking herd as replacement animals. Heat stress experienced by these females around the time they were conceived may confer long-lasting effects that alter subsequent milk production capacity. The objective of this study was to examine the relationship between periconceptional heat stress and subsequent milk production of primiparous cows. National Dairy Herd Improvement Association data was obtained from Dairy Records Management Systems. Records included Holstein cows that had completed at least one lactation in one of three states with large populations of dairy cattle and which are known for having hot, humid summers: Georgia, Florida or Texas. Dates of conception were calculated by subtracting 276 d from the recorded birth date of each individual cow. Records for cows conceived within the months of June, July, and August were retained as heat stress-conceived (HSC) cows (n = 94,440); cows conceived within the months of December, January, and February were retained as thermoneutral-conceived (TNC) contemporaries (n = 141,365). In order to account for the effects of environmental conditions on total milk production for a given lactation, cows were blocked by season of calving (winter, spring, summer or fall). Adjusted 305-day mature-equivalent milk production was evaluated with a mixed model ANOVA using SAS, in which random effects were used to account for variability between herds. Of the cows that calved in the summer, fall and winter, TNC cows had higher milk yield than the HSC cows in all states. Interestingly, the cows that calved in the spring presented a unique relationship, with HSC cows producing more milk. Overall however, heat stress at

    This study aimed to compare the effects of cabbage compression early breast care (CCEBC) and early breast care (EBC) on breast pain, breast hardness with general nursing breast care (GNBC) in primiparous women after cesarean birth. Sixty participants were divided to three groups including CCEBC, EBC and GNBC. Each group was treated with its intervention respectively more than 10 minutes before breast feeding from day two to day four after delivery. The primary outcomes were breast pain and breast hardness. Both CCEBC and EBC showed significantly lower pain level than GNBC at day 4 after delivery. There are significant differences of breast hardness among three groups. CCEBC group showed significantly lower breast hardness compared with EBC and GNBC. Neither core body temperature nor breast skin temperature was significantly different among the three groups. In conclusion, CCEBC may effective in relieving breast pain and breast hardness compared with EBC alone and GNBC in primiparous women after a cesarean birth. PMID:26885074

    To perform pelvimetry in nulliparous and primiparous women using 3 Tesla magnetic resonance imaging (3T MRI). Twenty-five nulliparous volunteers and 25 primiparous women underwent pelvic 3T MRI within one week after vaginal childbirth in a prospective clinical single-center trial. The pelvimetric parameters interspinous distance (ISD), intertuberous distance (ITD), sagittal outlet (SO), obstetric conjugate (OC), and coccygeal curved length (CCL) were adapted from anthropometric measurements as well as from sonographic and computed tomography-based pelvimetry performed on high-resolution T2-weighted images. We compared the results of the two study groups to one another, recent literature and postpartum-diagnosed levator ani muscle (LAM) injuries. The mean values for primipara/nullipara were ISD 107 ± 8.3/105 ± 8.4 mm, ITD 119.8 ± 10.2/118.4 ± 13.1 mm, OC 129.4 ± 10/130.8 ± 6.9 mm, SO 114.3 ± 7.8/112.5 ± 8.9 mm, and CCL 37.3 ± 7.4/39 ± 8 mm. Significant differences (P < 0.05) were found between the results for OC, SO, and CCL (primipara) and ISD, ITD and OC (nullipara) and the values in the literature. No significant difference in pelvimetric values was found between the groups. A significant correlation was found between the pelvimetric parameters and five types of LAM injuries. Two-dimensional 3T MRI combines high-resolution images with objective pelvimetric measurements applicable in a postpartum setting. Our results provide a good foundation for further MRI-based studies evaluating the bony pelvis and its relation to LAM injuries during vaginal childbirth. © 2018 Wiley Periodicals, Inc.

    Daily evaluation of rectal temperature (RT) during the first 10 d in milk (DIM) is used to facilitate the early identification of postpartum complications, particularly metritis in dairy cows. The factors associated with RT of postpartum dairy cows have not been clearly established and the RT threshold used to define fever has been variable. The objectives were to identify factors associated with the RT of postpartum dairy cows and provide descriptive statistics of the RT during the first 10 DIM to clarify the normal range of RT for cows. Daily RT was evaluated from 1 to 10 DIM for all cows calving during 2 consecutive summers on a single 1,500-cow Holstein dairy. Cows were placed into metabolic/digestive (METB), infectious (INF), and no recorded disease (NONE) groups based on disease diagnoses during the first 10 DIM. Cows were grouped based on calving difficulty and parity. Multiple linear regression models with repeated measures were used to evaluate the factors associated with RT. Three hundred and ninety-two cows were evaluated, of which 45% were primiparous and 32% required assistance at calving. No difference was observed in calving assistance by parity. First disease diagnoses peaked in the INF and METB groups at 3 and 1 DIM, respectively. The RT of primiparous cows was 0.1 to 0.2°C higher than that of multiparous cows from 1 to 8 DIM, accounting for calving difficulty, twin births, month of calving, and disease group in the model. The INF group cows had a higher RT than did NONE group cows (38.9±0.04 to 39.2±0.73 vs. 38.7±0.03°C, respectively) on each of the first 10 DIM, which was approximately 0.6°C higher from 3 to 5 DIM. The RT of cows with metritis was at least 0.1°C higher (38.8±0.05°C) than that of NONE group cows beginning 4 d before diagnosis. The mean RT of primiparous, defined healthy (NONE group) cows was 38.8±0.02°C, with an upper normal limit (mean+2 SD) of 39.6°C. The mean RT of multiparous cows in the NONE group during the first

  10. "I Just Want to Do Everything Right:" Primiparous Women's Accounts of Early Breastfeeding via an App-Based Diary.

    Science.gov (United States)

    Demirci, Jill; Caplan, Erin; Murray, Nora; Cohen, Susan

    Our objective was to describe the early breastfeeding experience of primiparous women. Healthy, primiparous women intending to exclusively breastfeed downloaded a commercial infant feeding mobile application (app) during their postpartum hospitalization. Women free-texted breastfeeding thoughts and experiences through 8 weeks postpartum in the app's diary. Diary content was qualitatively coded. Thirty-five participants completed diaries and were included in analyses. The overarching theme was Seeking sustainability and validation. Mothers felt overwhelmed, anxious, and frustrated with the intensity and unpredictability of breastfeeding and inconsistent professional breastfeeding support. The ability to exclusively breastfeed was seen as a bellwether of maternal competence. Breastfeeding progress was primarily measured through external feedback (e.g., weight checks) and managed through strict adherence to provider feeding plans. As breastfeeding problems and intensity abated, women exhibited optimism and assumed greater independence in feeding decisions. The primiparous breastfeeding experience is fraught with internally imposed and externally reinforced pressure to produce and persevere despite inadequate breastfeeding support infrastructure.

    We carried out a chart review study to determine the rate of diagnosis of dystocia (abnormal progress) and the use of cesarean section to treat dystocia among 3887 primiparous women who gave birth to a single baby in the vertex presentation at four hospitals in Ottawa-Carleton in 1984. Of the 3740 women who had some labour 1127 (30.1%) were given a diagnosis of dystocia. Cesarean section for dystocia was done during all phases of labour (41% of procedures in the latent phase, 38% in the active phase and 21% in the second stage). The cesarean section rate varied among the hospitals from 11.8% to 19.6%. A total of 75% of the cesarean sections were for dystocia, disproportion or failed induction. The findings suggest that cesarean section is being done for disproportion without a trial of labour beyond the latent phase and for dystocia in the absence of fetal distress. If these practices were modified the cesarean section rate could be reduced from 16% to about 8%, the rate found in some other centres and that observed in Canada in the early 1970s. PMID:2302643

    Conception rate and the calving interval of beef cows are known to be influenced by body reserves at calving and subsequent postpartum changes. However, few studies have focused on the effect of body reserve dynamics on both postpartum cyclicity and estrus expression. Two successive similar experiments (Year 1: n=14; Year 2: n=16) were carried out on primiparous Charolais cows reared indoors during winter to quantify the effects of adipose cell diameter at calving (ACDca) and their postpartum changes (ACDch) on cyclicity and estrus behavior. Cows were managed to calve with a body condition score (BCS, scale 0-5) of 2.5 (Year 1) and 1.5 (Year 2). After calving cows were assigned to a Low vs. a High energy level diet until turn out to pasture in May. Within years ACDca was similar between Low and High groups whereas calving to turnout changes of body weight (BW), BCS and adipose cell diameter differed (Pbody lipids to predict relationships between nutrition and reproduction in cows.

    to compare the pelvic floor muscle strength in primiparous women after normal birth and cesarean section, related to the socio-demographic characteristics, nutritional status, dyspareunia, urinary incontinence, perineal exercise in pregnancy, perineal condition and weight of the newborn. this was a cross-sectional study conducted after 50 - 70 postpartum days, with 24 primiparous women who underwent cesarean delivery and 72 who had a normal birth. The 9301 PeritronTM was used for analysis of muscle strength. The mean muscle strength was compared between the groups by two-way analysis of variance. the pelvic floor muscle strength was 24.0 cmH2O (±16.2) and 25.4 cmH2O (±14.7) in postpartum primiparous women after normal birth and cesarean section, respectively, with no significant difference. The muscular strength was greater in postpartum women with ≥ 12 years of study (42.0 ±26.3 versus 14.6 ±7.7 cmH2O; p= 0.036) and in those who performed perineal exercises (42.6±25.4 11.8±4.9 vs. cmH2O; p = 0.010), compared to caesarean. There was no difference in muscle strength according to delivery type regarding nutritional status, dyspareunia, urinary incontinence, perineal condition or newborn weight. pelvic floor muscle strength does not differ between primiparous women based on the type of delivery. Postpartum women with normal births, with higher education who performed perineal exercise during pregnancy showed greater muscle strength. comparar a força muscular do assoalho pélvico em primíparas no pós-parto normal e cesariana, relacionando-a às características sociodemográficas, estado nutricional, incontinência urinária, dispareunia, exercício perineal na gestação, condição perineal e peso do recém-nascido. estudo transversal realizado entre 50 e 70 dias de pós-parto, com 24 primíparas submetidas à cesariana e 72 ao parto normal.

    To determine whether rates of obstetric anal sphincter injuries (OASIS) are continuing to increase and whether risk of OASIS according to mode of delivery is constant over time. In a retrospective population-based study, data were obtained for vaginal singleton vertex deliveries at 37-41 weeks of pregnancy among primiparous women in New South Wales, Australia, between January 2001 and December 2011. Annual OASIS rates were determined among non-instrumental, forceps, and vacuum deliveries with and without episiotomy. Multivariable logistic regression was used to determine adjusted odds ratios for each delivery mode category by year. Trends in adjusted odds ratios over time for each delivery category were compared. OASIS occurred in 955 (4.1%) of 23 081 deliveries in 2001 and 1487 (5.9%) of 25 081 deliveries in 2011. After adjustment for known risk factors, the only delivery categories to show statistically significant increases in OASIS over the study period were non-instrumental deliveries without episiotomy (linear trend Pdeliveries with episiotomy (linear trend P=0.004). Overall, OASIS rates have continued to increase. Known risk factors do not fully explain the increase in OASIS rates in non-instrumental deliveries without an episiotomy and in forceps deliveries with an episiotomy. Crown Copyright © 2015.

    2012-02-01

    Pure Holstein (HO) cows (n=416) were compared with Normande (NO) × HO (n=251), Montbéliarde (MO) × HO (n=503), and Scandinavian Red (SR) × HO (n=321) crossbred cows for survival, lifetime production, and profitability in 6 commercial herds in California. The SR crossbred cows were sired by both Swedish Red and Norwegian Red bulls. Cows calved from June 2002 to January 2009. For analysis of survival to subsequent calvings, lifetime production, and profitability, data were restricted to 3 of 6 herds because they had at least 20 cows in each of the breed groups. All cows had the opportunity to calve at least 4 times. Best prediction, which is used by USDA for national genetic evaluations in the United States, was used to determine lifetime production to 4 yr (1,461 d) in the herd after first calving from test-day observations. Production and survival were estimated after 4 yr to calculate lifetime profit. A profit function was defined to include revenues and expenses for milk, fat, protein, and other solids production; somatic cell count; reproduction; feed intake; calf value; salvage value; dead cow disposal; and fixed cost. The NO × HO (1.2%), MO × HO (2.0%), and SR × HO cows (1.6%) had significantly fewer deaths than did pure HO cows (5.3%) during the first 305 d of first lactation. All crossbred groups had significantly more cows that calved a second, third, and fourth time, and had mean survival that was 300 to 400 d longer than did pure HO cows. The NO × HO, MO × HO, and SR × HO cows had significantly higher lifetime fat plus protein production than did pure HO cows up to 1,461 d after first calving. For profitability (ignoring possible differences in health costs), NO × HO cows had 26% greater projected lifetime profit per cow, but 6.7% less profit per cow-day, than did pure HO cows. On the other hand, MO × HO and SR × HO cows had 50 to 44%, respectively, more projected lifetime profit per cow and 5.3 to 3.6%, respectively, more projected profit

    Soil organic carbon (SOC) determines ecosystem functions, influencing soil fertility, soil physical, chemical and biological properties and crop productivity. Therefore the spatial pattern of SOC stocks and its appropriate management is important at various scales. Due to climate change and the contribution of carbon store in the soils, the national estimates of soil carbon stocks should be determined. Estonian soils have been well studied and mapped at a scale 1:10,000. Previous studies have estimated SOC stocks based on combinations of large groups of Estonian soils and the mean values of the soil profile database, but were not embedded into the geo-referenced databases. These studies have estimated SOC stocks of Estonian arable soils 122.3 Tg. Despite of available soil maps and databases, this information is still very poorly used for spatial soil modelling. The aim of current study is to assess and model spatial pattern of SOC stocks of arable soils on a pilot area Tartu County (area 3089 sq km). Estonian digital soil map and soil monitoring databases are providing a good opportunity to assess SOC stocks at various scales. The qualitative nature of the initial data from a soil map prohibits any straightforward use in modelling. Thus we have used several databases to construct models and linkages between soil properties that can be integrated into soil map. First step was to reorganize the soil map database (44,046 mapping units) so it can be used as an input to modelling. Arable areas were distinguished by a field layer of Agricultural Registers and Information Board, which provides precise information of current land use as it is the basis of paying CAP subsidies. The estimates of SOC content were found by using the arable land evaluation database of Tartu from the Estonian Land Board (comprising 950 sq km and 31,226 fields), where each soil type was assessed separately and average SOC content grouped by texture was derived. SOC content of epipedon varies in

    Smoking surveys among physicians have proved useful in highlighting the importance of physicians as healthy life style exemplars and role models in tobacco control and smoking cessation. The aim of this study was to give an overview of smoking behaviour among Estonian physicians from 1982 to 2014. Three cross-sectional postal surveys using a self-administered questionnaire were carried out among all practising physicians in Estonia. The number of physicians participating in this study was 3786 in 1982, 2735 in 2002, and 2902 in 2014. Data analysis involved calculating the age-standardized prevalences of smoking, prevalences of smoking by age group and mean age of smoking initiation. A non-parametric test for trend was used to assess significant changes in smoking over time. Age-standardized prevalence of current smoking among men was 39.7% in 1982, 20.9% in 2002, and 14.3% in 2014 and among women 12.2%, 8.0%, and 5.2%, respectively (p smoking among men and women was in age groups under 35 (from 55.2% to 16.7% and from 16.7% to 2.8%, respectively) and 35-44 (from 47.1% to 8.3% and from 19.5% to 5.1%, respectively) (p smoking initiation decreased from 20.4 to 19.3 among men and from 24.5 to 20.4 among women over the study period. In 1982-2014, smoking prevalence among Estonian physicians declined substantially. This may influence the willingness of society to recognize the health consequences of smoking which could give a support to the decline of the smoking epidemic in the country. Differences between smoking among male and female physicians persisted over the study period, but mean age of smoking initiation decreased. A further decline in smoking among Estonian physicians should be encouraged by special efforts targeted at physicians.

  4. Factors Affecting SSR in Holstein Dairy Cows

    Full Text Available Introduction Secondary sex ratio (SSR is the proportion of males to females at birth. It has been shown in many different mammalian species, many factors are associated with SSR. Changes in secondary sex ratio in dairy cows is considered economically important and the ability to change it could affect the revenues and profitability of a dairy farm. Thus, sperm or embryo sexing techniques in recent years has attracted more attention. Most breed of dairy cattle are more likely to have female calf is born to use them as replacement heifers and in order to maintain their productive herd number. On the contrary, when the goal is the production of meat, bull calves due to higher growth rates and production efficiency, are more convenient and more economically efficient. The aim of present study was to investigate some key factors affecting SSR in Iranian Holstein cows. According to Fisher, the sex ratio in the population under the control of natural selection is not always the same. There is overwhelming evidence to support the theory that shows Fisher Primary and secondary sex ratio sex ratio can deviate from this balance and natural selection caused a change in this ratio can be in certain circumstances. For example, the secondary sex ratio of 52:48 has been reported in dairy cows. Studies on mammalian species suggest that several factors, including latitude of the location, the dominant regional climate model, time and frequency of mating to ovulation, diet, age of parents, physical score, breed and produced eggs from ovarian left or right can have a significant effect on the secondary sex ratio. Weather conditions may modify the internal environment and the effect on physiological mechanisms or through the impact on the frequency and type of foods available to parents, the secondary sex ratio is impressive. The impact on the quantity and quality of parent's access to food sources in many species of mammals, the sex ratio has been fixed. Previous

    The aim of this study was to explore Chinese women's perceptions of maternal role competence and factors contributing to maternal role competence during early motherhood. Developing a sense of competence and satisfaction in the maternal role are considered critical components in maternal adaptation, which have a significant impact on parenting behaviours and the psychosocial development of the child. However, qualitative studies that address maternal role competence are limited in the Chinese population. This was an exploratory descriptive study. A purposive sample of 26 Chinese primiparous mothers participated in a childbirth psychoeducation programme and was interviewed at six weeks postpartum. Data were analysed using content analysis. Women perceived a competent mother as being able to make a commitment to caring for the physical and emotional well-being of child, while cultivating appropriate values for childhood. Personal knowledge and experience of infant care, success in breastfeeding, infant's well-being, availability of social support and contradictory information from various sources were major factors affecting maternal role competency. The findings highlight the importance of understanding Chinese cultural attitudes to childrearing and maternal role competence. New Chinese mothers need information on child care, positive experiences of infant care, social support and consistent information to enhance their maternal role competency. Recommendations are made for Chinese culturally specific guidelines and healthcare delivery interventions to enhance maternal role competence in early motherhood. Nursing and midwifery care should always take into account the cultural beliefs and enable adaptation of traditional postpartum practices. Providing consistent information and positive experience on parenting skills and infant behaviour as well as enhancing effective coping strategies could strengthen Chinese women's maternal role competency. © 2011 Blackwell

    The prevalence of fear of childbirth in pregnant women is described to be about 20-25%, while 6-10% of expectant mothers report a severe fear that impairs their daily activities as well as their ability to cope with labour and childbirth. Research on fear of childbirth risk factors has produced heterogeneous results while being mostly done with expectant mothers from northern Europe, northern America, and Australia. The present research investigates whether fear of childbirth can be predicted by socio-demographic variables, distressing experiences before pregnancy, medical-obstetric factors and psychological variables with a sample of 426 Italian primiparous pregnant women. Subjects, recruited between the 34th and 36th week of pregnancy, completed a questionnaire packet that included the Wijma Delivery Expectancy Questionnaire, the Edinburgh Postnatal Depression Scale, the State-Trait Anxiety Inventory, the Dyadic Adjustment Scale, the Multidimensional Scale of Perceived Social Support, as well as demographic and anamnestic information. Fear of childbirth was treated as both a continuous and a dichotomous variable, in order to differentiate expectant mothers as with a severe fear of childbirth. Results demonstrate that anxiety as well as couple adjustment predicted fear of childbirth when treated as a continuous variable, while clinical depression predicted severe fear of childbirth. Findings support the key role of psychological variables in predicting fear of childbirth. Results suggest the importance of differentiating low levels of fear from intense levels of fear in order to promote adequate support interventions. Copyright © 2017 Australian College of Midwives.

    Full Text Available The article concentrates on Estonian novels depicting Soviet prison camps in the 1940s and 1950s. The goal is to map themes, motifs and characteristics in such novels, concentrating on various taboos and rules in the prison camp environment. For a long time the Soviet prison camp theme was not publicly discussed in Estonia due to political reasons. Texts dealing with prison camps could appear in print only outside the Soviet Union; the way Estonians saw these historical events and hellish experiences were depicted mostly in exile novels. Most notable are the novels by Arved Viirlaid (b. 1922, e.g., Kes tappis Eerik Hormi? (Who Killed Eerik Horm? (1974, Surnud ei loe (The Dead do not Read (1975, Vaim ja ahelad (Mind and Chains (1961. Estonian prison camp novels can be seen as “the literature of testimony”, to use the term by Leona Toker. Dramatic historical events are written down to record the events and to show the inhumane nature of Soviet society. These records of the dramatic past follow certain patterns and create certain self- and hetero-images. A prison camp is a closed territory within a closed territory; prison camps can be seen as small models of Soviet society. Prison camp novels give a detailed view of the environment of the prison camp, its inhabitants and activities. Two central aspects are labour and food; the life of the prisoner whirls around these. The most important thing is to survive, which often leads to moral decline, e.g., stealing, cheating. However, there are lines Estonians do not cross, e.g., cannibalism or homosexual relationships with superiors. Estonians are always depicted as political prisoners (not common criminals and heterosexuals, while Russians are portrayed mainly as criminals and often also as homosexuals. Another important component of the image of the Estonians is their enterprising spirit and ability to manage even under very difficult conditions. Therefore, several oppositions can be identified, e

    To study the long-term mental health consequences of the 1986 Chernobyl nuclear accident among cleanup workers from Estonia. In 2010, 614 Estonian Chernobyl cleanup workers and 706 geographically and age-matched population-based controls completed a mail survey that included self-rated health, the Posttraumatic Stress Disorder Checklist (PCL), alcohol symptoms (AUDIT), and scales measuring depressive, anxiety, agoraphobia, fatigue, insomnia, and somatization symptoms. Respondents were dichotomized into high (top quartile) and low symptom groups on each measure. Logistic regression analysis detected significant differences between cleanup workers and controls on all measures even after adjustment for ethnicity, education, marital status, and employment status. The strongest difference was found for somatization, with cleanup workers being three times more likely than controls to score in the top quartile (OR = 3.28, 95% CI 2.39-4.52), whereas for alcohol problems the difference was half as large (OR = 1.52, 95% CI 1.16-1.99). Among cleanup workers, arrival at Chernobyl in 1986 (vs. later) was associated with sleep problems, somatization, and symptoms of agoraphobia. The toll of cleanup work was evident 24 years after the Chernobyl accident among Estonian cleanup workers indicating the need for focused mental health interventions.

    One purpose of this project was the establishment of a radon monitoring programme inside the state environmental monitoring programme. Another purpose was to investigate regions, expected to have high radon levels indoors. A new method for the long-term measurement of indoor radon was established and the staff for these measurements was trained. The results of the measurement can be used by Estonian decision-makers to work out rules and standards. There is no legislative act in the field of radiation in Estonian at this time. To summarize the results of the measurements we can say that indoor radon concentrations vary by region. The radon investigations must be continued to identify the risk areas and types of housing construction. The results of the state radon monitoring are provided to the municipalities, who advice the owners of planned new houses to select the right construction for the house. A new project will follow with an investigation of radon in randomly selected dwellings, training and equipment for radon measurement in soil, and general advice with regard to radon, as well as assistance in preparing information about radon. 7 refs, 5 figs

    Diprosopus was diagnosed in six German Holstein calves born on different dairy farms. The degree of facial duplication varied from a partial doubling of the nostrils and upper jaw to complete duplication of the face with formation of two mouths, four eyes and four ears. Further calves descending from the same parents or dams and calves from the same farms were not affected. A joint pedigree was ascertained for the calves with diprosopus. Furthermore, a previously reported case of diprosopus could be traced back to the same ancestors of this pedigree. Consequently, we detected the first time a familial accumulation of diprosopus. Since the ancestors showed no signs of diprosopus and the frequency of diprosopus in German Holsteins is presumably low, an oligogenic inheritance is likely. Recessive genes or a combination of recessive and dominant genes may cause this anomaly.

    We present a comprehensive study of the spectral and transport properties in the Anderson–Holstein model both in and out of equilibrium using the functional renormalization group (fRG). We show how the previously established machinery of Matsubara and Keldysh fRG can be extended to include the local phonon mode. Based on the analysis of spectral properties in equilibrium we identify different regimes depending on the strength of the electron–phonon interaction and the frequency of the phonon mode. We supplement these considerations with analytical results from the Kondo model. We also calculate the nonlinear differential conductance through the Anderson–Holstein quantum dot and find clear signatures of the presence of the phonon mode. (paper)

    Full Text Available This article aims to give an overview of literary instruction in schools of the russification era at the beginning of the 20th century in Estonia; this was likewise the curriculum of literary study offered to the generation of educated youth which included the Young Estonians. Based on official documents, archival materials, and memoirs, and through analyses of anthologies, literary histories, and teaching methods in use at the time, we attempt to reconstruct the outlines of literary reading and requirements for students in various types of schools. When, as a result of school reform, Russian became the language of instruction; lessons in Russian became central in the curriculum, alongside the word of God; selections from Russian literature were read in the original language. In the lower grades, teaching was by the so-called ”natural method”, intended to guarantee swift achievement of fluency in ”living Russian language”; this was later replaced by systematic textual analysis, which distinguished between belles lettres and other types of texts. However, the study of literature was always subordinated to the goals of language instruction. In institutions of secondary education, study of Russian literature was separate from language instruction. Indeed, Russian literature was the only literature systematically studied in high schools (though one must keep in mind that not all schools completely followed the official program. Private schools were especially noticeable for their greater freedom, though all of them had to take general curriculum directives into account. Reading of literary texts connected with other languages thus had to remain almost purely illustrative. In view of the above, in the upper grades of elementary school and high school, students obtained a thorough introduction to the Russian classics. According to the official school curriculum, Russian literary history ended with Nikolai Gogol. Attempts were made to ignore

  19. Identity and Othering in Past and Present: Representations of the Soviet Era in Estonian Post-Soviet Textbooks

    2018-02-01

    Full Text Available This paper analyses representations of the ‘core Soviet era’ (1945-1985 in Estonian post-Soviet history textbooks (1989-2016. Attitudes towards the Soviet system have been a rich resource for identity building, and hence a powerful political tool across the whole of the post-Soviet block. Based on an analysis of sections about the Soviet era in Estonia in 21 textbooks, the paper takes a look at how textbooks reflect broader processes of social meaning making, identity building and othering after a profound social and political turn. In 1989 and during the early 1990s, perspectives and narratives in Estonian history textbooks were closely related to social memory and national politics, enacting a specific social representation of the Soviet era that dominated the Estonian-speaking public space during the 1990s. The Soviet era, Russia and local Russians became the main Others for Estonia and Estonians. Over time, public discourse has diversified. The national curriculum and textbooks, however, still maintain the canon that formed in 1990s and thus reflect earlier sentiments. Apart from the increasing salience of Soviet-era daily life in more recent textbooks, the thematic choices and emphases have changed little since the 1990s. Therefore, even if the style of writing has ‘cooled down’, issues of identity preservation, resistance and accommodation, together with a saliently negative representation of wrongdoings by the Soviet system, still prevail. On the one hand, this testifies to the resilience of an established tradition in the textbook genre in general. On the other hand, it reflects the dominance of an ethnocentric tradition in Estonian history textbook writing. The paper discusses the implications of these findings for interethnic relations in Estonia.

    Full Text Available Strains of live Saccharomyces cerevisiae yeast have exhibited probiotic effects in ruminants. This study investigated the effects of the dietary yeast supplement, S. cerevisiae (Yea-Sacc1026, on primiparous (PP and multiparous (MP Egyptian buffaloes in early to mid-lactation. Lactating buffaloes were fed either a basal total mixed ration (TMR, control; 4 PP and 8 MP or the basal TMR plus 10 g Yea-Sacc1026 per buffalo cow per day (yeast; 4 PP and 8 MP. The feeds were given from 15 days prepartum to 180 days postpartum. Feed intake, body weight, and milk yields (MY were recorded, and milk and blood samples were collected for analyses. Feces were collected from days 45 to 47 during early lactation and from days 90 to 92 during mid-lactation to determine apparent digestibility of dry matter (DM, organic matter (OM, crude protein (CP and crude fiber (CF. Energy corrected milk yield (ECM, feed conversion, and energy and nitrogen conversion efficiency were calculated. Yeast treated MP buffaloes consumed more DM (P ≤ 0.041 and CP than the untreated control group. Apparent digestibility of DM and OM were significantly greater at mid-lactation for treated versus control group (P = 0.001. Crude fiber digestibility was greater in MP than in PP buffaloes (P = 0.049, and yeast supplemented MP cows had a greater CF digestibility than control MP buffaloes at mid-lactation (P = 0.010. Total blood lipids decreased after yeast supplementation (P = 0.029. Milk yields, ECM, fat and protein yields increased for yeast treated MP buffaloes (P ≤ 0.039. The study concluded that the response to yeast supplementation in buffalo cows is parity dependent. Multiparous buffaloes respond to yeast supplementation with an increased DM intake and CF digestibility without significant weight gains, allowing a greater ECM yield with less fat mobilization. Supplementing buffaloes with yeast culture may increase milk production in early lactation and results in a

    Full Text Available Giving birth is a critical time for many species and is often the most painful event ever experienced by females. In domestic species, like the pig, pain associated with parturition represents a potential welfare concern, and the consequences of pain can cause economic losses (e.g., by indirectly contributing to piglet mortality as pain could slow post-farrowing recovery, reduce food and water intake, reducing milk let-down. This study investigated pain assessment and its management in primiparous (gilts and multiparous (sows breeding pigs, including the provision of a non-steroidal anti-inflammatory drug (NSAID post-parturition. Individuals were randomly allocated to receive the NSAID ketoprofen (3 mg/kg bodyweight (n = 11 gilts, 16 sows or the equivalent volume of saline (n = 13 gilts, 16 sows by intramuscular injection 1.5 h after the birth of the last piglet. Data collected included putative behavioral indicators of pain (back leg forward, tremble, back arch, salivary cortisol concentrations pre-farrowing and up to 7 days post-injection. In addition, post-partum biomarkers of inflammation, including the acute phase protein C-reactive protein (CRP and 3 porcine cytokines [interleukin-1 β (IL1 β, interleukin-6 (IL6, and tumor necrosis factor α (TNF α] were measured in plasma collected 6 h following the injection. Behaviors were analyzed using generalized linear mixed models, and physiological variables with linear mixed models. No difference in putative pain behaviors, salivary cortisol, CRP, or cytokines were found between individuals treated with ketoprofen or those administered the saline control. However, there were some differences between gilts and sows, as sows exhibited more putative pain behavior than gilts, had higher salivary cortisol on the day of farrowing and had higher plasma TNF α. Conversely, gilts had higher salivary cortisol than sows on day 3 post-farrowing and had higher CRP. This indicates that, like human females

    Full Text Available Introduction: Episiotomy is used for enlarging the perineum. Aloe vera and Calendula have been used for treating different diseases from ancient times, limited researches have been done regarding the healing of these plants. Since the effect of their ointment on episiotomy healing has not been studied, this study is being done for determining the impact of Aloe vera and Calendula on episiotomy healing in primiparous women. Methods: This clinical trial involves 111 qualified primiparous women admitted in Lolagar hospital. They were randomly categorized into three groups of control (n=1 and experimental (n=2 groups. The women in experimental group used Aloe vera and Calendula Ointment every 8 hours and the control group used hospital routine on episiotomy for 5 days. The data were collected by demographic questionnaire and redness, edema, ecchymosis, discharge and approximation scale (REEDA which investigated the episiotomy healing before and five days after intervention in two groups. ANOVA, Tukey test, Kruskal-wallis, Chi-square were used for data analysis. Results: The three groups do not have statistically significant different regarding demographic and other intervening variables. Comparing the mean of REEDA in five days after delivery showed statistically significant difference between control and experimental groups.Conclusion: According to the results, using Aloe vera and Calendula ointment considerably increases the speed of episiotomy wound healing so it can be used for quickening the episiotomy healing.

    Full Text Available Background: Pain is one of the side effects of episiotomy. The virtual reality (VR is a non-pharmacological method for pain relief. The purpose of this study was to determine the effect of using video glasses on pain reduction in primiparity women during episiotomy repair. Methods: This clinical trial was conducted on 30 primiparous parturient women having labor at Omolbanin Hospital (Mashhad, Iran during May-July 2012. Samples during episiotomy repair were randomly divided into two equal groups. The intervention group received the usual treatment with VR (video glasses and local infiltration 5 ml solution of lidocaine 2% and the control group only received local infiltration (5 ml solution of lidocaine 2%. Pain was measured using the Numeric Pain Rating Scale (0-100 scale before, during and after the episiotomy repair. Data were analyzed using Fisher’s exact test, Chi-square, Mann-Whitney and repeated measures ANOVA tests by SPSS 11.5 software. Results: There were statistically significant differences between the pain score during episiotomy repair in both groups (P=0.038. Conclusion: Virtual reality is an effective complementary non-pharmacological method to reduce pain during episiotomy repair. Trial Registration Number: IRCT138811063185N1.

    Probiotics have been suggested to modify placental trophoblast inflammation, systemic inflammation, and blood pressure, all potentially interesting aspects of preeclampsia. The authors examined the association between consumption of milk-based probiotic products in pregnancy and development of preeclampsia and its subtypes. The study was performed in the Norwegian Mother and Child Cohort Study by using a prospective design in 33,399 primiparous women in the years 2002-2008. The intake of milk-based products containing probiotic lactobacilli was estimated from a self-reported food frequency questionnaire. Preeclampsia diagnoses were obtained from the Norwegian Medical Birth Registry. Intake of probiotic milk products was associated with reduced risk of preeclampsia. The association was most prominent in severe preeclampsia (adjusted odds ratio (OR) = 0.79, 95% confidence interval (CI): 0.66, 0.96). With probiotic intakes divided into categories representing no, monthly, weekly, or daily intake, a lower risk for preeclampsia (all subtypes) was observed for daily probiotic intake (OR = 0.80, 95% CI: 0.66, 0.96). Lower risks for severe preeclampsia were observed for weekly (OR = 0.75, 95% CI: 0.57, 0.98) and daily (OR = 0.61, 95% CI: 0.43, 0.89) intakes. These results suggest that regular consumption of milk-based probiotics could be associated with lower risk of preeclampsia in primiparous women.

    Full Text Available The governmental initiative called the Compatriots Programme, which supports language tuition in Estonian schools and societies abroad, reveals an increased interest in developing intergenerational language transmission in the growing Estonian diaspora. This transnational language political activity signals a new era in language policy, where nation states are increasingly decentralized by migration. The evaluation of the program furthermore reveals that organizing such schools requires a willingness to take language political agency, typically conducted by well-educated and well-integrated resourceful transnational multilingual parents. The present article outlines the results of an ethnographic study of the process of establishing the Estonian School in Copenhagen. This step has demanded a change in the mindset still prevailing in Estonia that language political activities, such as planning language acquisition, are solely the responsibility of the state. Since the prevailing language ideology in Denmark is not favorable towards multilingualism in migrant languages, intergenerational language transmission furthermore presupposes a feeling of ownership of the language and high language self-esteem.

    Reduced female fertility could cause considerable economic loss and has become a worldwide problem in the modern dairy industry. The objective of this study was to detect quantitative trait loci (QTL) for female fertility traits in Chinese and Nordic Holsteins using various strategies. First, single-trait association analyses were performed for female fertility traits in Chinese and Nordic Holsteins. Second, the SNPs with P-value Nordic Holsteins. Third, the summary statistics from single-trait association analyses were combined into meta-analyses to: (1) identify common QTL for multiple fertility traits within each Holstein population; (2) detect SNPs which were associated with a female fertility trait across two Holstein populations. A large numbers of QTL were discovered or confirmed for female fertility traits. The QTL segregating at 31.4~34.1 Mb on BTA13, 48.3~51.9 Mb on BTA23 and 34.0~37.6 Mb on BTA28 shared between Chinese and Nordic Holsteins were further ascertained using a validation approach and meta-analyses. Furthermore, multiple novel variants identified in Chinese Holsteins were validated with Nordic data as well as meta-analyses. The genes IL6R, SLC39A12, CACNB2, ZEB1, ZMIZ1 and FAM213A were concluded to be strong candidate genes for female fertility in Holsteins.

    Lying behavior is an important measure of comfort and well-being in dairy cattle, and changes in lying behavior are potential indicators and predictors of lameness. Our objectives were to determine individual and herd-level risk factors associated with measures of lying behavior, and to evaluate whether automated measures of lying behavior can be used to detect lameness. A purposive sample of 40 Holstein cows was selected from each of 141 dairy farms in Alberta, Ontario, and Québec. Lying behavior of 5,135 cows between 10 and 120 d in milk was automatically and continuously recorded using accelerometers over 4 d. Data on factors hypothesized to influence lying behavior were collected, including information on individual cows, management practices, and facility design. Associations between predictor variables and measures of lying behavior were assessed using generalized linear mixed models, including farm and province as random and fixed effects, respectively. Logistic regression models were used to determine whether lying behavior was associated with lameness. At the cow-level, daily lying time increased with increasing days in milk, but this effect interacted with parity; primiparous cows had more frequent but shorter lying bouts in early lactation, changing to mature-cow patterns of lying behavior (fewer and longer lying bouts) in late lactation. In barns with stall curbs >22 cm high, the use of sand or >2 cm of bedding was associated with an increased average daily lying time of 1.44 and 0.06 h/d, respectively. Feed alleys ≥ 350 cm wide or stalls ≥ 114 cm wide were associated with increased daily lying time of 0.39 and 0.33 h/d, respectively, whereas rubber flooring in the feed alley was associated with 0.47 h/d lower average lying time. Lame cows had longer lying times, with fewer, longer, and more variable duration of bouts compared with nonlame cows. In that regard, cows with lying time ≥ 14 h/d, ≤ 5 lying bouts per day, bout duration ≥ 110 min

    Forty-eight Holstein cows (32 multiparous and 16 primiparous) in mid to late lactation averaging 219±71 days in milk and 30.5±6.6 kg/d of 3.5% fat-corrected milk were used in a 56-d completely randomized design experiment to evaluate condensed corn distillers solubles (CCDS) inclusion in high-fiber total mixed rations (TMR). Inclusion rates evaluated were 0, 6.6, 13.2, and 19.8% CCDS as a percentage of dry matter (DM). Distiller solubles substituted for soybean meal, corn grain, and whole cottonseed such that diets were similar in protein (16.6%) and fat (4.50%). Water was added to 0, 6.6, and 13.2% CCDS treatments so that final TMR DM concentrations (47.8%) were similar across diets. The forage portion of the diet was kept constant at 19.6% annual ryegrass hay and 26.0% sorghum baleage. Diet in vitro true digestibility tended to increase as CCDS addition increased, but neutral detergent fiber digestibility trended lower in CCDS diets. Percent P (0.39, 0.55, 0.69, and 0.73%) and S (0.32, 0.35, 0.39, and 0.42%) in TMR increased as CCDS concentration increased. Milk yield (23.5, 24.7, 25.5, and 24.8 kg/d of 3.5% fat-corrected milk) was similar for control and CCDS diets. Milk fat (3.88, 3.73, 3.78, and 3.68%), protein (3.28, 3.27, 3.31, and 3.31%), and lactose (4.61, 4.66, 4.69, and 4.77) percentages were similar across diets. Milk urea nitrogen (16.60, 15.58, 15.43, and 14.75 mg/dL) declined with increasing CCDS addition. Animal activity, body weight, body condition scores, and locomotion scores were not influenced by CCDS. Day 28 poststudy locomotion scores were similar across diets. Ruminal acetate concentrations did not differ among diets, but propionate and butyrate concentrations were elevated in rumen fluid of cows receiving 19.6% CCDS. Although rumen fluid pH values were similar (6.5, 6.4, 6.3, and 6.2), the two highest CCDS diets exhibited depressed acetate:propionate ratios relative to controls. The results from this study indicate that CCDS may be

    Estonian is a morphologically rich Finno-Ugric language with nominal paradigms that have at least 28 different inflected forms but sometimes more than 40. For languages with rich inflection, it has been argued that whole-word frequency, as a diagnostic of whole-word representations, should not be predictive for lexical processing. We report a lexical decision experiment, showing that response latencies decrease both with frequency of the inflected form and its inflectional paradigm size. Inflectional paradigm size was also predictive of semantic categorization, indicating it is a semantic effect, similar to the morphological family size effect. These findings fit well with the evidence for frequency effects of word n-grams in languages with little inflectional morphology, such as English. Apparently, the amount of information on word use in the mental lexicon is substantially larger than was previously thought. Copyright © 2018 Elsevier B.V. All rights reserved.

    Full Text Available The laser-induced breakdown spectroscopy (LIBS combined with multivariate regression analysis of measured data were utilised for determination of the heating value and the chemical composition of pellets made from Estonian oil shale samples with different heating values. The study is the first where the oil shale heating value is determined on the basis of LIBS spectra. The method for selecting the optimal number of spectral lines for ordinary multivariate least squares regression model is presented. The correlation coefficient between the heating value predicted by the regression model, and that measured by calorimetric bomb, was R2=0.98. The standard deviation of prediction was 0.24 MJ/kg. Concentrations of oil shale components predicted by the regression model were compared with those measured by ordinary methods.

    Full Text Available Recession has sharply erected the question of tax burden and the optimal proportion of different kinds of taxes among the incomes of the budget. Indirect taxes and consumption taxes, which proportion is different according to different methodologies, dominate in Estonian state budget. The buoyancy of a tax system based on taxes of that kind is especially weak during the recession. Difficulties concerning the incomes of budget have arisen the necessity for lifting taxes, which is possible as the tax burden is low now. But a sharp question of the optimal level of taxes is going to be raised. A formula for indirect tax optimum according to Ramsey taxes and Slutski decomposition has been proposed in the article.

    Full Text Available The article investigates the selection and sequencing of the idioms encountered in two locally-produced and international coursebook series currently employed in Estonian basic schools. It is hypothesized that there exists a positive correlation between idioms’ difficulty and coursebooks’ language proficiency level. The hypothesis is tested through a statistical analysis of the idioms found which are categorized in terms of their analysability into three categories where category 1 includes analysable semi-literal idioms, category 2 comprises analysable semi-transparent idioms, and category 3 encompasses non-analysable opaque idioms, and then analysed through an online language corpus (British National Corpus. The results of the study reveal that the coursebook authors under discussion have disregarded idioms’ frequency as a criterion for selection or sequencing, whereas the factor utilized to some extent is the degree of analysability.

    Full Text Available The purpose of the study was to find out whether the conceptual connection of emotion and motion is holding in the domain of personality traits. In a quantitative study 40 Estonian terms of personality traits were investigated and a conclusion was driven that, indeed, the qualities of emotionality and motion are perceived as co-present characteristics. In further data analysis some visualized measures were applied in order to get further insights into the hidden structure of the data. The self-organizing map (SOM analysis revealed an additional dimension of axiological evaluations present in the semantics and the SOM meta-analysis technique revealed groups of near synonymous words as well as gave overview of the more general structure common in the two data sets. The latter was tentatively explained by the person’s habitual level of activation.DOI: http://dx.doi.org/10.5128/ERYa6.21

    2011-05-17

    The aim of this paper is to compare the changes in the utilization of species from various hemeroby categories (indicating the degree of sensitivity of the plant to human impact) using historical data concerning the years 1888-1994. The authors digitised 8808 handwritten reports, reflecting local ethnopharmacological knowledge from 8 selected collections from the Estonian Folklore Archives of the Estonian Literary Museum. They were semi-quantitatively analyzed according to the sensitivity to human impact of 540 taxa that could possibly be related to the plant vernacular names given in the reports. Although in different periods of time the number of ethnopharmacologically used plants has changed, the proportion of plants utilized from each group has remained relatively same, consisting on average of: 23% anthropophytes, 42% apophytes, 32% hemeradiaphores and 3% hemerophobes. Comparison of the application of the most used plants revealed considerable changes of plant utilization, in which the varied use of the most popular anthropophytes increased and the applied scope of the most popular hemeradiaphores and hemerophobes decreased almost by twofold in one century. Case studies on seven taxa are presented, of them, use of Allium sativum L., Aesculus hippocastanum L. and Mentha xpiperita L. increased, whereas the use of Hordeum L., Orchidaceae, Paris quadrifolia L. and Briza media L. decreased greatly. This research contributes to the better understanding of the cognitive and human ecological concepts underlying the use of medicinal plants in Estonia. Strong increase in the ethnomedical utilization of plants depending on human influence, and a decrease in the use of taxa that do not prefer human activities indicates that, despite some of the population still have access to natural resources and diverse knowledge of the medical use of plants, the majority relies on a very narrow selection and a rather restricted herbal landscape.

    Full Text Available The aim of this research was to define methods for early prediction (based on I. milk control record of lactation flow in Holstein heifers as well as to choose optimal one in terms of prediction fit and application simplicity. Total of 304,569 daily yield records automatically recorded on a 1,136 first lactation Holstein cows, from March 2003 till August 2008., were included in analysis. According to the test date, calving date, the age at first calving, lactation stage when I. milk control occurred and to the average milk yield in first 25th, T1 (and 25th-45th, T2 lactation days, measuring monthcalving month-age-production-time-period subgroups were formed. The parameters of analysed nonlinear and linear methods were estimated for each defined subgroup. As models evaluation measures,adjusted coefficient of determination, and average and standard deviation of error were used. Considering obtained results, in terms of total variance explanation (R2 adj, the nonlinear Wood’s method showed superiority above the linear ones (Wilmink’s, Ali-Schaeffer’s and Guo-Swalve’s method in both time-period subgroups (T1 - 97.5 % of explained variability; T2 - 98.1 % of explained variability. Regarding the evaluation measures based on prediction error amount (eavg±eSD, the lowest average error of daily milk yield prediction (less than 0.005 kg/day, as well as of lactation milk yield prediction (less than 50 kg/lactation (T1 time-period subgroup and less than 30 kg/lactation (T2 time-period subgroup; were determined when Wood’s nonlinear prediction method were applied. Obtained results indicate that estimated Wood’s regression parameters could be used in routine work for early prediction of Holstein heifer’s lactation flow.

    Chromium (Cr) has been reported to enhance immune function and improve insulin sensitivity and performance in beef and dairy cattle. However, its effect on bovine macrophage inflammatory and metabolic response is unknown. The objective of this study was to characterize the effect of dietary Cr on the inflammatory and metabolic response of polarized macrophages ex vivo. Twelve primiparous and 16 multiparous healthy Holstein cows in mid lactation (143 ± 37 d in milk) were enrolled in this study. Cows were fed a common total mixed ration once per day that was top-dressed with 200 g of ground corn containing 1 of 2 dietary treatments: control (CTL, no Cr supplementation) or Cr propionate (CrP, 8 mg of Cr/cow per day) for 35 d. At d 1, 17, and 35 of treatment, blood monocytes were isolated and cultured to obtain 3 monocyte-derived macrophage (MDM) phenotypes: M0 (non-polarized), M1 (pro-inflammatory; IFN-γ polarized) and M2 (anti-inflammatory; IL-4 polarized). The experiment was set in a randomized complete block design. Neither dry matter intake nor milk yield was affected by treatment. Plasma concentrations of metabolites and the metabolic and inflammatory response of MDM in spent media were not affected by treatment. Neither the whole blood cell population nor the specific proportion of leukocytes was affected by the main effect of treatment. However, we did observe a trend for fewer circulating neutrophils in cows fed CrP than in cows fed CTL for 35 d, which may be partly attributable to a greater influx of neutrophils into peripheral tissues, a reduced pro-inflammatory response during disease, or both; this warrants future study. Expression of IGFI was increased in MDM-M0, and expression of CXCL11 tended to increase in MDM-M2 from cows fed CrP compared with cows fed CTL. Expression of SLC2A3 also tended to increase in MDM-M2 from cows fed CrP compared with cows fed CTL at 17 d. Our results suggest that CrP has minimal effect on the inflammatory and metabolic

    Osteogenesis imperfecta (OI) is a rare bone disorder. In 90% of cases, OI is caused by mutations in the COL1A1/2 genes, which code procollagen α1 and α2 chains. The main aim of the current research was to identify the mutational spectrum of COL1A1/2 genes in Estonian patients. The small population size of Estonia provides a unique chance to explore the collagen I mutational profile of 100% of OI families in the country. We performed mutational analysis of peripheral blood gDNA of 30 unrelated Estonian OI patients using Sanger sequencing of COL1A1 and COL1A2 genes, including all intron-exon junctions and 5'UTR and 3'UTR regions, to identify causative OI mutations. We identified COL1A1/2 mutations in 86.67% of patients (26/30). 76.92% of discovered mutations were located in the COL1A1 (n = 20) and 23.08% in the COL1A2 (n = 6) gene. Half of the COL1A1/2 mutations appeared to be novel. The percentage of quantitative COL1A1/2 mutations was 69.23%. Glycine substitution with serine was the most prevalent among missense mutations. All qualitative mutations were situated in the chain domain of pro-α1/2 chains. Our study shows that among the Estonian OI population, the range of collagen I mutations is quite high, which agrees with other described OI cohorts of Northern Europe. The Estonian OI cohort differs due to the high number of quantitative variants and simple missense variants, which are mostly Gly to Ser substitutions and do not extend the chain domain of COL1A1/2 products.

    The rate of cesarean delivery (CD) in Brazil has increased over the past 40 years. The CD rate in public services is three times above the World Health Organization recommended values. Among strategies to reduce CD, the most important is reduction of primary cesarean. This study aimed to describe factors associated with CD during labor in primiparous women with a single cephalic pregnancy assisted in the Brazilian Public Health System (SUS). This study is part of the Birth in Brazil survey, a national hospital-based study of 23,894 postpartum women and their newborns. The rate of CD in primiparous women was estimated. Univariate and multivariable logistic regression was performed to analyze factors associated with CD during labor in primiparous women with a single cephalic pregnancy, including estimation of crude and adjusted odds ratios and their respective 95 % confidence intervals. The analyzed data are related to the 2814 eligible primiparous women who had vaginal birth or CD during labor in SUS hospitals. In adjusted analyses, residing in the Southeast region was associated with lower CD during labor. Occurrence of clinical and obstetric conditions potentially related to obstetric emergencies before delivery, early admission with women cared for by at least one nurse midwife. The CD rate in primiparous women in SUS in Brazil is extremely high and can compromise the health of these women and their newborns. Information and support for vaginal birth during antenatal care, avoiding early admission, and promoting the use of good practices during labor assistance can reduce unnecessary CD. Considering the experience of other countries, incorporation of nurse midwives in childbirth care may increase the use of good practices during labor.

    2013-01-01

    Full Text Available The purpose of the study is to evaluate how supportive is Estonian national innovation system toward the launching of new innovative products by high technology firms. The article intends to combine two broad areas of research – national innovation system approach and the different models of the new product launching. Based on the literature review and in-depth analysis of three case studies of Estonian high-tech company’s major barriers as well success factors of highly innovative product launches were identified. The barriers of the new product launching were linked with the systemic failures of the national innovation system. The most relevant failures of Estonian national innovation system inhibiting the new product development are capability and networking failures. The sources of innovation of high-technology firms are too narrow, linkages with domestic firms and higher education institutions as well with foreign firms are poorly developed. High-tech firms have also serious capacity problems due to the extremely weak support mechanism by national innovation system on the seed funding stage of product development and prototype building stage as well. Paper argues that resources needed for the innovation should not be looked too narrowly following linear innovation model approach. Instead interactive approach is needed, which combines capability building, network development, interactive learning with direct investments into fundamental research.

    We sought to characterize risk factors of urinary incontinence (UI) during pregnancy and the postpartum period in primiparous women in China. We enrolled 10,098 women from the seven regions of China ≥28 weeks' gestation from September 2007 to May 2009 and administered the Bristol Female Lower Urinary Tract Symptoms questionnaire to estimate the presence of different types of UI during late pregnancy (37 to 42 weeks' gestation) and at 6 weeks and 6 months postpartum. We also collected details of pregnancy and childbirth and demographic data. McNemar's test, multinomial logistic regression models, and binary logistic regression models were used. Multivariable analysis revealed six independent risk factors for SUI: age, more frequent exercise, alcohol consumption, higher body mass index, larger waist circumference, and history of constipation. For those with no UI in late pregnancy, 3.7% and 3.0% developed new cases at 6 weeks and 6 months postpartum, respectively. Risk factors for UI at 6 months were frequent exercise, rural residence, perineal laceration, and lateral episiotomy. Prevalence of all UI was 26.7% in late pregnancy, 9.5% at 6 weeks postpartum, and 6.8% at 6 months postpartum. Most cases were stress urinary incontinence (18.6%, 6.9%, and 5.0%, at the respectively times). Rates of UI in primiparous women in China are consistent with those reported elsewhere. Rural location, frequent exercise, and birth-related injuries are risk factors for UI at 6 months postpartum.

    Full Text Available OBJECTIVE: To assess the prevalence of urinary incontinence and associated vaginal squeeze pressure in primiparous women with and without previous gestational diabetes mellitus two years post-cesarean delivery. METHODS: Primiparous women who delivered by cesarean two years previously were interviewed about the delivery and the occurrence of incontinence. Incontinence was reported by the women and vaginal pressure evaluated by a Perina perineometer. Sixty-three women with gestational diabetes and 98 women without the disease were screened for incontinence and vaginal pressure. Multiple logistic regression models were used to evaluate the independent effects of gestational diabetes. RESULTS: The prevalence of gestational incontinence was higher among women with gestational diabetes during their pregnancies (50.8% vs. 31.6% and two years after a cesarean (44.8% vs. 18.4%. Decreased vaginal pressure was also significantly higher among women with gestational diabetes (53.9% vs. 37.8%. Maternal weight gain and newborn weight were risk factors for decreased vaginal pressure. Maternal age, gestational incontinence and decreased vaginal pressure were risk factors for incontinence two years after a cesarean. In a multivariate logistic model, gestational diabetes was an independent risk factor for gestational incontinence. CONCLUSIONS: The prevalence of incontinence and decreased vaginal pressure two years post-cesarean were elevated among women with gestational diabetes compared to women who were normoglycemic during pregnancy. We confirmed an association between gestational diabetes mellitus and a subsequent decrease of vaginal pressure two years post-cesarean. These results may warrant more comprehensive prospective and translational studies.

    2005-07-01

    The esterification of 2-hydroxy-4-(methylthio)-butanoic acid (HMB) to isopropanol (HMBi) decreases the rate and extent of its ruminal breakdown. The modes of action of HMB and HMBi appear to be different. The quantification of the production response to HMBi has not been done. The objectives of this study were (1) to determine the lactation response to HMB, (2) to determine the lactation response to HMBi, and (3) to evaluate whether the response to HMBi is affected by HMB in the diet. Sixty-one Holstein cows (24 primiparous, 37 multiparous) were assigned to 1 of 4 dietary treatments 21 to 28 d after calving. The base diet consisted of [on a dry matter (DM) basis] 32.5% corn silage, 17.5% alfalfa hay, 10% whole cottonseed, and 40% of a pelleted concentrate made primarily of ground corn, soybean meal, and blood meal, and was fed for 16 wk as a control diet. To prepare the dietary treatments, the base diet was supplemented with 0.1% of diet DM with HMB (treatment 2), with 0.15% HMBi (treatment 3), or with 0.045% HMB and 0.15% HMBi (treatment 4). Results showed a significant increase in milk yield (2.9 kg/d), protein content (0.15%), protein yield (115 g/d), fat yield (165 g/d), and lactose yield (182 g/d) from HMBi. Supplementation of HMB had small and nonsignificant effects on milk yield and composition. There were no significant interaction effects of HMB with HMBi on any of the production traits measured in this experiment. Plasma free Met as a proportion of essential amino acids was increased by HMBi, but not by HMB. Dietary supplementation of HMBi increased gross N efficiency expressed as the proportion of ingested N secreted in milk. Consequently, HMBi significantly improved N efficiency.

    Full Text Available The aim of this study was to investigate factors influencing the number of daughters of Holstein bulls during the progeny testing using data provided by the Italian Holstein Friesian Cattle Breeders Association. The hypothesis is that there are no differences among artificial insemination studs (AIS on the daughters distribution among progeny testing bulls. For each bull and beginning from 21 months of age, the distribution of daughters over the progeny testing period was calculated. Data were available on 1973 bulls born between 1986 and 2004, progeny tested in Italy and with at least 4 paternal half-sibs. On average, bulls exited the genetic centre at 11.3±1.1 months and reached their first official genetic proof at 58.0±3.1 months of age. An analysis of variance was performed on the cumulative frequency of daughters at 24, 36, 48, and 60 months. The generalized linear model included the fixed effects of year of birth of the bull (18 levels, artificial insemination stud (4 levels and sire of bull (137 levels. All effects significantly affected the variability of studied traits. Artificial insemination stud was the most important source of variation, followed by year of birth and sire of bull. Significant differences among AI studs exist, probably reflecting different strategies adopted during progeny testing.

    Full Text Available ABSTRACT The use of animals from dairy farms is an alternative to meat production since it provides an increment of total income for farmers. This study aims to evaluate the performance of Holstein calves finished in two feeding systems (feedlot or pasture. Forty-three animals with 58 days old and 57 kg were divided in two treatments: 23 animals finished in feedlot with corn silage plus concentrate based on corn and soybean meal (40:60; 20 animals kept in cultivated pastures according to the period of the year: Italian ryegrass (Lolium multiflorum and pearl millet (Pennisetum americanum with supplementation with the same feedlot-concentrate at 1% body weight. Animals were slaughtered with 200 kg. Dry matter and nutrient intake were determined, with the use of chromium oxide for estimating pasture intake. Feedlot animals had greater total intake and total digestible nutrients, resulting in higher average daily gain (0.949 vs 0.694 kg day-1. Crude protein intake, neutral detergent fiber and feed conversion did not show significant differences. Holstein calves have improved performance when finished in feedlot.

    Full Text Available Ketosis is a metabolic disorder closely associated with liver lipidosis. Numerous tests have been developed to detect hepatic dysfunction in dairy cows. Bromosulfophthalein (BSP clearance is established as a sensitive index of hepatic function. The objective of this study was to examine the difference of biliary excretion of BSP between ketotic and healthy Holstein cows and to correlate this excretion with other indicators of liver dysfunction. Twenty puerperal Holstein cows divided in two groups (10 cows each were involved in the study. The first group included healthy and the second group ketotic cows. Blood samples were taken 10 days after parturition. Concentrations of total protein, albumin, total bilirubin, Ca, P, total lipids, urea and glucose were determined. Immediately after blood sampling, BSP test was performed. Blood samples were taken 5 and 45 minutes after injection, and the percentage of retained pigment in the sample obtained at minute 45 was calculated. Blood albumin and glucose concentrations were significantly higher in healthy then ketotic cows. Total bilirubin concentration was significantly higher in ketotic than healthy cows. BSP excretion was significantly higher in ketotic compared to healthy cows. There was a significant positive correlation between BSP values and total bilirubin concentrartions in both healthy and ketotic cows and a significant negative correlation between BSP values and glucose concentrartions in both healthy and ketotic cows. In conclusion, biliary clearance of BSP may be used as a reliable method for the detection of hepatic dysfunction associated with clinical symptoms of ketosis in dairy cows.

  17. Kolm Eesti Robinsoni: Daniel Defoe romaan eesti tõlkes / Three Estonian Robinsons: Daniel Defoe’s Novel in Estonian Translation

    Full Text Available The article discusses three Estonian translations of Daniel Defoe’s Robinson Crusoe into Estonian with the focus on the completeness of the translated texts and the characterisation given to these in paratextual information. While there are several translations and versions of the tex t available in E stonian that have either used a mediating language or do not proceed directly from Defoe’s novel, three editions explicitly list Defoe’s English-language Robinson Crusoe as their source text. These are Rudolf Sirge’s translation from 1950 and two editions translated by Valter Rummel that appeared in 1984 (reprinted in 2001 and 2007, respectively. The article sets out to discover the main differences between the three editions and the possible reasons that may have triggered their publication in Estonia at those particular times. In order to approach the issues, a general framework derived from descriptive translation studies is employed with an emphasis on Gideon Toury’s chrestomatic treatment of translation norms. Thus an attempt is made to detect the preliminary translational norms regarding translation policy, particularly the choice of texts to be translated, as well as the matricial norms that concern the fullness of the translated text and are part of operational norms manifested in the translator’s decisions which, in two of the cases at hand, may also have been decisions made by the editor or the censor. Rudolf Sirge’s translation appeared at a time when Estonia had fairly recently been incorporated into the Soviet Union and there was a lack of children’s literature ideologically appreciated by the regime. This may account for the packaging of the book as a work with a strong didactic bent, while its primary audience was taken to be children and young adults for whom the protagonist served as an example of a hard-working and tenacious hero to be emulated by young Soviets. The target text has been considerably shortened as

    Full Text Available In this paper, we compare the use and functions of definite and indefinite article-like determiners in Estonian and Finnish. Our main aim is to explore whether the factors that explain the choice of particular determiner forms are similar in Estonian and Finnish. We use a picture-sequence based elicitation experiment to collect spoken narratives from adult native speakers of Estonian and Finnish, and apply non-parametric tree and forest models to analyze the data. Our findings indicate that number of mention and animacy are important predictor variables in both languages, but their exact effect is divergent. We also find that in Finnish, case of the determiner NP proves to be an important factor, while in Estonian, syntactic role of the NP explains some aspects of determiner form choice. Nevertheless, the overall usage frequency of determiners is modest in the Estonian and Finnish data, and the process of grammaticalizing articles is only in initial stages in both languages. *** Artikliga, artiklita?

    Complex Vertebral Malformation, a congenital and lethal genetic defect of Holstein breed, has been recently observed in different Countries all over the world. In this paper the AA describe the clinical and radiological aspects of CVM in a two day old female calf. The disease was characterized by low body weight, symmetrical arthrogryposis and partial rotation of all legs and scoliosis. Calf was alert and showed physiological appetite, but was not able to maintain the quadrupedal stance. Radiographs of the vertebral column showed multiple vertebral anomalies, including hemivertebrae, fused and misshapen vertebrae and ribs and scoliosis, that affected mainly the caudal, cervical and thoracic regions. At necropsy, besides the skeleton anomalies, complex malformation of the heart was observed, which included atrial and interventricular defects and patent ductus arteriosus. This is the first case of CVM completely documented and genetically tested in Italy [it

    Full Text Available Cardiac auscultation of a 10-day-old diarrheic female Holstein dairy calf revealed irregularities in rhythm and absence of 4th heart sound. Electrocardiogram (ECG and blood sample were obtained before and after the treatment. Based on ECG and cardiac auscultation findings, atrial fibrillation (AF was diagnosed. Serum sodium, calcium and magnesium before treatment were significantly lower than their reference ranges and potassium was significantly higher. One day after treating this patient, serum electrolytes were reached to reference ranges and AF was changed to normal sinus rhythm. Based on resolving the AF after treating the patient and correcting the electrolyte imbalances, it can be suggested that electrolyte imbalances were the main cause of the occurrence of AF in the present case.

    2004-01-01

    A seven-year old Holstein cow was referred to the Saint Hyacinth (Quebec) veterinary school for anorexia, progressive weight loss, rapid decline in milk production and abdominal pain. Due to the presence of abdominal and thoracic fluid, abdominal pain and tachycardia with jugular pulse, initially a possible diagnosis was traumatic reticuloperitonitis and pericarditis, but excluded after radiography and ultrasonography. On exploratory laparotomy, numerous 1 to 50 mm diameter nodules were seen on the peritoneum and throughout the abdominal serosa. The animal was euthanased due to the presence of generalised tumour. On histopathology, a mesothelioma was diagnosed. Mesothelioma is rarely diagnosed in cattle. However, it is impossible to know whether this is due to its rarity or to the fact that it may be easily mistaken for other diseases and its histological diagnosis is currently difficult [it

    The principles of energy policy in Schleswig-Holstein set forward in this brochure are neither an energy programme nor a descriptive report on the policy of the day. Rather, they are intended to mark the energy-political frame of action within which the government of the Land will more. At the same time their purpose is to provide a medium-term orientation for politics and the power economy, consumers and producers. They are thus consciously made to contrast with political trends conceiving energy policy first of all as a plan-dependent activity. With these guiding principles the government of the Land consistantly continues an energy policy it has exposed in detail in its answer to the Question submitted by the CDU parliamentary party on December 8, 1980.

    Interventions to prevent postpartum common mental disorders (PCMD) among unselected populations of women have had limited success. The aim was to determine whether What Were We Thinking (WWWT) a gender-informed, psychoeducational programme for couples and babies can prevent PCMD among primiparous women 6 months postpartum. Cluster-randomised controlled trial. 48 Maternal and Child Health Centres (MCHCs) from 6 Local Government Areas in Melbourne, Australia were allocated randomly to usual care (24) or usual care plus WWWT (24). English-speaking primiparous women receiving primary care at trial MCHCs were recruited to the intervention (204) and control (196) conditions. Of these, 187 (91.7%) and 177 (90.3%) provided complete data. WWWT is a manualised programme comprising primary care from a trained nurse, print materials and a face-to-face seminar. Data sources were standardised and study-specific measures collected in blinded computer-assisted telephone interviews at 6 and 26 weeks postpartum. The primary outcome was PCMD assessed by Composite International Diagnostic Interviews and Patient Health Questionnaire (PHQ) Depression and Generalised Anxiety Disorder modules. In intention-to-treat analyses the adjusted OR (AOR) of PCMD in the intervention compared to the usual care group was 0.78 (95% CI 0.38 to 1.63, ns), but mild to moderate anxiety symptoms (AOR 0.58, 95% CI 0.35 to 0.97) and poor self-rated health (AOR 0.46, 95% CI 0.22 to 0.97) were significantly lower. In a per protocol analysis, comparing the full (three component) intervention and usual care groups, the AOR of PCMD was 0.36, (95% CI 0.14 to 0.95). The WWWT seminar was appraised as salient, comprehensible and useful by >85% participants. No harms were detected. WWWT is readily integrated into primary care, enables inclusion of fathers and addresses modifiable risks for PCMD directly. The full intervention appears a promising programme for preventing PCMD, optimising family functioning, and as the

    A 3-yr study using primiparous crossbred beef heifers (n = 114) was conducted to determine the effects of protein supplement during late gestation on progeny performance and carcass characteristics. Pregnant heifers were stratified by heifer development system, initial BW, and AI service sire and placed in an individual feeding system. Heifers were offered meadow hay (8 to 11% CP) from early November to mid-February and provided no supplement (CON; n = 37), 0.83 kg/d (DM basis) of a dried distillers grains with solubles-based supplement (HI; n = 39), or 0.83 kg/d (DM basis) of a dried corn gluten feed-based supplement (LO; n = 38). Supplements were designed to be isonitrogenous (28% CP) and isocaloric but to differ in RUP with HI (59% RUP) having greater levels of RUP than LO (34% RUP). After the individual feeding period, heifers were placed in a drylot for calving. All heifers were bred using a fixed-timed AI protocol and pairs were moved to a commercial ranch in the Nebraska Sandhills for summer grazing. Calf weaning BW did not differ (P = 0.14) based on maternal diet. However, feedlot entry BW was greater (P = 0.03) for HI compared with CON calves. Average daily gain during the initial feedlot phase tended (P = 0.10) to be greatest for calves born to CON dams and lowest for calves born to LO dams. However, overall ADG was similar (P = 0.50) for the entire feedlot period. Residual feed intake during the reimplant and total feeding period was improved in calves born to supplemented dams in yr 2 and 3 compared with calves born to CON dams. There was no difference in final BW among treatments (P = 0.71). Hot carcass weight was similar (P = 0.72) among treatments; however, steers had greater (P RUP supplements, similar to those used in this study, to primiparous heifers in late gestation consuming ad libitum grass hay resulted in increased initial feedlot BW for HI compared to CON calves, improved feed efficiency, and altered carcass characteristics in calves born

    Two 9-year old Estonian Salix plantations suffering from dieback were studied: one situated on poor mineral soil and divided into fertilised and unfertilised plots (Saare plantation) and another growing on a well-decomposed and nitrogen-rich organic soil, without fertiliser application (Kambja plantation). Bacteria from internal tissues of visually damaged shoots from seven clones were isolated in spring and autumn. The strains were subsequently biochemically characterised and tested for ice nucleation activity and pathogenicity on Salix. Some strains were also analysed with 16S rRNA. High numbers of culturable bacteria were found, belonging mainly to Erwinia, Sphingomonas, Pseudomonas and Xanthomonas spp. Fertilised plots were significantly more colonised by bacteria than unfertilised plots and also more extensively damaged, showing a lower density of living plants after 7 years of culture. More ice nucleation active (INA) strains were found in Saare fertilised plots and at Kambja than in Saare unfertilised plots. Likewise, most pathogenic strains were isolated from Saare fertilised plots and from Kambja. For some of the willow clones studied, dieback appeared to be related to both clonal frost sensitivity and abundance of INA and pathogenic bacteria. The plantations probably suffered from the presence of high amounts of pathogens and from frost related injuries aggravated by INA bacteria. Most probably the fertilisation at Saare and the nitrogen-rich soil at Kambja created a favourable environment for bacterial development and led to high dieback levels after the first harvest.

  17. Estonian energy system: Proposals for the implementation of a cogeneration strategy

    2000-01-01

    Since the Soviet era Estonia inherited oil-shale-based electricity plants, with a capacity of 3000 MW. Oil shale now provides Estonia with very low electricity prices. However, most of the stations are very old. Half of them were built before 1965, and sooner or later the old oil shale production units will have to be replaced. Estonia will then have to face serious increases in electricity production prices. At the same time Estonia has problems in restoring its district heating systems. The prices are rising and may consumers have converted to other heating sources such as electric heating. The major long-term strategic policy choices to make in Estonia are to decide (1) whether the oil shale power stations should be replaced by new centralized production units such as new oil shale stations or nuclear power, or (2) whether the electricity production should be decentralized. In the centralized solution (oil shale or nuclear power), the domestic heating will be left to boilers or electric heating leading to a very high primary energy supply. In the decentralized solution, Estonia could benefit from the advantage of cogeneration leading to very low fuel consumption. But this latter strategy depends on the restoration of the district heating systems. This article seeks to form a strategy to improve the efficiency of the Estonian energy system by increasing the use of cogeneration. (author)

    Factors affecting Estonian forests are: The environmental, specially atmospheric pollution, - the foundation of new forests as monoculture on unsuitable locations, - mechanical damages by unsuitable forest machinery, - unfavourable water conditions, - Heterobasidion or Armillaria rot roots. Local damages in consequence of air pollutants are distributed in environments of Tallinn, Kivioli, Kohtla-Jaerve and the thermal power stations (Narva), where the SO 2 -content in the air is on the average higher than 50 (80) μg/m 3 . Pine forests on dry sand soils (600 ha damaged in 1989) and the older spruce forests show the new type of forest decline. High Al-ion concentration, disturbances of the Ca-Mg-metabolism, an extreme nutrient deficit, (specially N-deficit) and periodical water deficit as well as pathogenic fungi are damaging the trees. Spruces show nonspecific defoliation, needle necrosis, needlefall, occurence of fungal diseases. More damaged are the spruce forests in regions with basic precipitations and high sulphur-deposition.

    To examine factors associated with early sexual intercourse among 15 to 16-year-old adolescents by gender. The data were collected from a random sample of Estonian basic schools' ninth grade pupils in 1999 using self-completed questionnaires. A multivariate logistic regression analysis for boys and girls was used to test for associations between sexual intercourse, and personal gender role-related attitudes, attitudes towards sexual intercourse, pubertal timing, smoking status and experience of drunkenness. Of the respondents, 14.6% of boys and 13.1% of girls had experienced sexual intercourse. Traditional gender role-related attitudes were associated with sexual intercourse among girls, but not among boys. Smoking and experience of drunkenness was strongly associated with sexual intercourse for both genders. Gender differences in the association between gender role-related attitudes and early sexual intercourse were observed among 15 to 16-year-olds in Estonia. Smoking and experience of drunkenness were strongly related to sexual intercourse for both genders.

    The present paper is based on a WHO Collaborative Cross-National Study "Health Behavior in School-Aged Children (HBSC)." It aimed at describing and analyzing how the sexual behaviors of 13- to 15-year-old Estonian school children were associated with self-reported depressive feelings and suicidality. Distinctive behavioral traits in relation to age of first sexual intercourse were also investigated. Self-reported questionnaires from school children (n = 3,055) were analyzed. In total, 15.2% of school children reported being nonvirgin. Among 13-year-olds, 2.9% of girls and 6.8% of boys were nonvirgins. Approximately 25% of the 15-year-old girls and boys were nonvirgins. The likelihood of depressive feelings and suicidal ideation increased significantly in both genders with loss of virginity. Boys who had lost their virginity at 13 years or younger were 4.2 times more likely to have suicidal thoughts; comparable girls were 7.8 times more likely to have suicidal thoughts. Compared to virgins, youths who had lost their virginity reported poor self-assessed health and more risk behaviors in themselves and their peers. Experiences of sexual intercourse increased the odds ratios for depressive feelings and suicidality. The earlier sexual intercourse was initiated, the greater were the odds of lower mental well-being. Risk behaviors emerged as a complex phenomenon requiring complex prevention.

    Full Text Available The paper analyses issues related to supervision and support of early career researchers in Estonian academia. We use nine focus groups interviews conducted in 2015 with representatives of social sciences in order to identify early career researchers’ needs with respect to support, frustrations they may experience, and resources they may have for addressing them. Our crucial contribution is the identification of wider support networks of peers and colleagues that may compensate, partially or even fully, for failures of official supervision. On the basis of our analysis we argue that support for early career researchers should take into account the resources they already possess but also recognise the importance of wider academic culture, including funding and employment patterns, and the roles of supervisors and senior researchers in ensuring successful functioning of support networks. Through analysing the conditions for the development of early career researchers – producers of knowledge – our paper contributes to social epistemology understood as analysis of specific forms of social organisation of knowledge production.

The purpose of this study was to identify genetic regions strongly associated with milk traits (milk production, fat, and protein using Korean Holstein data. Methods This study was performed using single nucleotide polymorphism (SNP chip data (Illumina BovineSNP50 Beadchip of 911 Korean Holstein individuals. We inferred each genomic estimated breeding values based on best linear unbiased prediction (BLUP and ridge regression using BLUPF90 and R. We then performed a genome-wide association study and identified genetic regions related to milk traits. Results We identified 9, 6, and 17 significant genetic regions related to milk production, fat and protein, respectively. These genes are newly reported in the genetic association with milk traits of Holstein. Conclusion This study complements a recent Holstein genome-wide association studies that identified other SNPs and genes as the most significant variants. These results will help to expand the knowledge of the polygenic nature of milk production in Holsteins.

    Full Text Available Changes in the Estonian National Museum from 1909 to the presentThe Estonian National Museum was founded in Tartu in 1909 as part of the national movement. With its activities and connections in society, the ENM helped create Estonian society, the nation’s collective memory and identity.The ENM has always been – despite the changing locations, names, and content – one of the symbols of national identity. But at the same time, ENM has never had its own building designed specially for the museum’s purposes.Since 1909 there have been several attempts to establish a home for the ENM. At first (1909–1923, Estonian society wanted to establish the museum in the center of Tartu. The museum was intended to become a key institution of the growing nation and establishing the nation’s identity.At last in 1923 the ENM secured the Raadi manor, outside the center of the city, in a beautiful park, near the lake with its boats and water attractions. In this manor the first permanent exhibition of mainly 19th century Estonian peasant life was compiled, and the ENM operated in the Raadi manor from 1923–1940 as the “Estonian’s own museum” The years of alternating occupations, World War II, and political terror damaged and destroyed the whole society. The Raadi manor was destroyed in the war too, and the ENM itself was divided into two parts – the State Ethnographic Museum and the State Literary Museum. The collections of the ENM were given to Tallinn and to many different places inside and outside Tartu. Then began “the period of temporary location” that continues today. The museum is located in several places in the city of Tartu.In 1988, the prior name of the State Ethnographic Museum – the Estonian National Museum – was reinstated. Since the 1990s there have been many attempts to secure a special building for the ENM. Now, at last, as a result of serious economic pressure, we are closer to this goal than ever.

    This research investigated the effects of different breastfeeding training techniques for primiparous mothers before discharge on the incidence of cracked nipples. This was a controlled intervention study that was carried out between 2015 and 2016 on 90 mothers living in İzmir. The mothers were divided into three groups: the demonstration-based training group, brochure group, and routine care-receiving group. The mothers in the "brochure group" were provided with breastfeeding training brochures. Mothers in the demonstration-based training group received one-to-one training using designed doll and puppet tools. The rate of cracked nipples at age 2 weeks was 63.3% in the routine care-receiving group, 56.7% in the brochure group, and 20% in the demonstration-based training group. At the end of the fourth week, the rate was 30% in the routine care-receiving group and less than 10% in the other two groups (p raining group than in the other two groups (p roups in the percentage of exclusive breastfeeding. The results documented that breastfeeding training based on one-to-one demonstration utilizing specially designed audiovisual tools was more effective than the other two methods in the prevention of nipple cracks.

    The objective was to examine the relationship between maternal and perinatal factors and the occurrence of stress (SUI) or mixed (MUI) urinary incontinence (UI) 1 year after the first vaginal delivery in primiparous women. Participants in this prospective cohort were recruited consecutively from June 2003 to July 2005 from all eligible women who delivered in the department. A validated questionnaire, the International Consultation of Incontinence Questionnaire Short Form (ICIQ-SF) was completed by all participants 2-3 days after delivery, and a similar second questionnaire was filled out 1 year later. Additional data were obtained from the medical records. The first questionnaire was completed by 1,018 women (63 %) and the second by 859 women (84 %). The study group comprised the 575 women without any UI before the pregnancy and who had a vaginal delivery. The primary analysis comprised 117 women with either SUI or MUI 1 year after the vaginal delivery and 403 women without any UI. In univariate analyses, the following factors were associated with SUI or MUI: prepregnancy body mass index (BMI) ≥ 30 (p pregnancy (p pregnancy [adjusted odds ratio (OR) 4.7, 95 % confidence interval (CI) 2.9-7.7) and inversely associated with oxytocin augmentation (adjusted OR 0.5, 95 % CI 0.3-0.9). SUI or MUI 1 year after the first vaginal delivery was strongly associated with UI during the pregnancy and inversely associated with oxytocin augmentation.

    Full Text Available Abstract Background Preeclampsia is a frequent syndrome and its cause has been linked to multiple factors, making prevention of the syndrome a continuous challenge. One of the suggested risk factors for preeclampsia is advanced maternal age. In the Western countries, maternal age at first delivery has been steadily increasing, yet few studies have examined women of advanced maternal age with preeclampsia. The purpose of this registry-based study was to compare the obstetric outcomes in primiparous and preeclamptic women younger and older than 35 years. Methods The registry-based study used data from three Finnish health registries: Finnish Medical Birth Register, Finnish Hospital Discharge Register and Register of Congenital Malformations. The sample contained women under 35 years of age (N = 15,437 compared with those 35 and over (N = 2,387 who were diagnosed with preeclampsia and had their first singleton birth in Finland between 1997 and 2008. In multivariate modeling, the main outcome measures were Preterm delivery (before 34 and 37 weeks, low Apgar score (5 min., small-for-gestational-age, fetal death, asphyxia, Cesarean delivery, induction, blood transfusion and admission to a Neonatal Intensive Care Unit. Results Women of advanced maternal age (AMA exhibited more preeclampsia (9.4% than younger women (6.4%. They had more prior terminations (25 ( Conclusions Preeclampsia is more common in women with advanced maternal age. Advanced maternal age is an independent risk factor for adverse outcomes in first-time mothers with preeclampsia.

    The present study aimed to (a) characterize the personal competencies, the social resources, and the psychosocial adjustment (psychological distress, quality of life, and parenting self-perceptions) during the early postpartum period of primiparous women of advanced age (≥35 years at the time of delivery) and their partners (older parents) compared with that of younger first-time mothers (20-34 years) and their partners (younger parents); and (b) explore the role of personal competencies and social resources in couples' psychosocial adjustment, depending on the age group. Older (n = 74) and younger parents (n = 71) completed self-report measures to assess personal competencies and social resources (third trimester of pregnancy), psychological distress, and quality of life (third trimester of pregnancy and 1-month' postpartum) and parenting self-perceptions (1-month' postpartum). Older parents were more similar than different from younger parents regarding personal competencies, social resources, and psychosocial adjustment during the first postnatal month. Regardless of the age group, higher personal competencies and social resources predicted lower anxiety and more positive parenting self-perceptions in women. Beyond higher personal competencies, older maternal age also predicted higher quality of life. In men, higher personal competencies were protective against anxiety, but only at older maternal age. © 2015 Michigan Association for Infant Mental Health.

    The purpose of this study was to create a Turkish version of the Pregnancy-Related Anxiety Questionnaire-Revised 2 (PRAQR2), which was revised for application to multiparous and primiparous pregnancy, and to explore its psychometric characteristics in multiparous and primiparous pregnancy. This study was methodologically designed to assess the reliability and validity of the PRAQ-R2. The study was carried out in the obstetrics clinic of a training and research hospital in Malatya. A total of 616 healthy pregnant women (399 multiparous and 217 primiparous) constituted the sample of the study. The cultural adaptation process of the questionnaire was conducted in three phases: language validity, content validity, and pilot application. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were used to test the construct validity of the questionnaire. The reliability of the PRAQ-R2 was evaluated with Cronbach's alpha internal consistency coefficient, item-total correlation, test-retest analysis, and parallel forms reliability. The EFA revealed that the PRAQ-R2 consists of 10 items for the multiparous group and 11 for the primiparous group after adding the item ``I am anxious about the delivery because I have never experienced one before.'' The CFA for both groups supported the three-factor questionnaire yielded by the EFA. Good fit index values were obtained in both groups. Cronbach's alpha internal consistency coefficient ranged from 0.81 to 0.93 for the multiparous group and 0.87 to 0.94 for the primiparous group for the complete PRAQ-R2 and each of its subdimensions. In addition, the item-total correlation, test-retest analysis, and parallel forms reliability of the questionnaire were highly correlated. The PRAQ-R2 is a valid and reliable instrument that can be used to evaluate the level of anxiety in Turkish pregnant women irrespective of parity. The use of the PRAQ-R2 in prenatal healthcare services will contribute to the early diagnosis

    parenting during infancy is highly problematic for Chinese primiparous women. As an important determinant of good parenting, maternal self-efficacy (MSE) should be paid more attention by researchers. At present, the limitations of previous research about MSE during infancy are that the factors which influence MSE remained poorly explored, there were few studies with Chinese women, and the studies did not consider the effect of different cultures. to explore factors which influence MSE in primiparous women in China in the first three months postnatally. a quantitative longitudinal study using questionnaires was conducted. In total, 420 Chinese primiparous women were recruited in obstetric wards at three hospitals in Xiamen City, Fujian Province of China. Initial baseline questionnaires to measure socio-demographic and clinical characteristics were distributed to participants face-to-face by the researcher on the postnatal ward at three days postnatally. Follow-up questionnaires at six and 12 weeks postnatally were sent via e-mail by the researcher to participants, including the Self-efficacy in Infant Care Scale (SICS), the Edinburgh Postnatal Depression Scale (EPDS) and the Postpartum Social Support Scale (PSSS) to measure MSE, postnatal depression symptoms and social support, respectively. These were returned by participants via e-mail. Quantitative data were analysed using SPSS. the variables: social support, women's satisfaction with 'Doing the month', postnatal depression, maternal education, baby health, and maternal occupation had an influence on MSE at six weeks postnatally (Adjusted R 2 = 0.510, F = 46.084, Pwomen's satisfaction with 'Doing the month', and baby fussiness were the factors influencing MSE at 12 weeks postnatally (Adjusted R 2 = 0.485, F = 41.082, Pwomen's family members need to be aware of the significant contribution of social support, women's satisfaction with 'Doing the month' in positively influencing primiparous women's MSE, and the

    Full Text Available Abstract Background The rate of cesarean delivery (CD in Brazil has increased over the past 40 years. The CD rate in public services is three times above the World Health Organization recommended values. Among strategies to reduce CD, the most important is reduction of primary cesarean. This study aimed to describe factors associated with CD during labor in primiparous women with a single cephalic pregnancy assisted in the Brazilian Public Health System (SUS. Methods This study is part of the Birth in Brazil survey, a national hospital-based study of 23,894 postpartum women and their newborns. The rate of CD in primiparous women was estimated. Univariate and multivariable logistic regression was performed to analyze factors associated with CD during labor in primiparous women with a single cephalic pregnancy, including estimation of crude and adjusted odds ratios and their respective 95 % confidence intervals. Results The analyzed data are related to the 2814 eligible primiparous women who had vaginal birth or CD during labor in SUS hospitals. In adjusted analyses, residing in the Southeast region was associated with lower CD during labor. Occurrence of clinical and obstetric conditions potentially related to obstetric emergencies before delivery, early admission with < 4 cm of dilatation, a decision late in pregnancy for CD, and the use of analgesia were associated with a greater risk for CD. Favorable advice for vaginal birth during antenatal care, induction of labor, and the use of any good practices during labor were protective factors for CD. The type of professional who attended birth was not significant in the final analyses, but bivariate analysis showed a higher use of good practices and a smaller proportion of epidural analgesia in women cared for by at least one nurse midwife. Conclusions The CD rate in primiparous women in SUS in Brazil is extremely high and can compromise the health of these women and their newborns

    Superovulation of dairy cattle is frequently used in Canada. The cost of this protocol is high, and so is the variability of the outcome. Knowing the superovulatory potential of a donor cow could influence the breeder's decision to superovulate it or not. The main objective of this study was to perform a genetic analysis for superovulatory response of Holstein cows in Canada using data recorded by Holstein Canada, and to investigate if these data could be used for genetic evaluation. Data contained the total number of embryos and the number of viable embryos from every successful flushing performed across Canada. After editing, 137,446 records of superovulation performed between 1992 and 2014 were analyzed. A univariate repeatability animal model analysis was performed for both total number of embryos and number of viable embryos. Because both data and residuals did not follow a normal distribution, records were subject to either logarithmic or Anscombe transformation. Using logarithmic transformation, heritability estimates (SE) of 0.15 (0.01) and 0.14 (0.01) were found for total number of embryos and number of viable embryos, respectively. Using Anscombe transformation, heritability estimates (SE) of 0.17 (0.01) and 0.14 (0.01) were found for total number of embryos and number of viable embryos, respectively. The genetic correlation between the 2 traits was estimated at 0.97 using logarithmic transformation and 0.95 using Anscombe transformation. Breeding values were estimated for 54,463 cows, and 3,513 sires. Only estimated breeding values of sires having a reliability higher than 40% were considered for estimated breeding values correlations with other routinely evaluated traits. The results showed that selection for a higher response to superovulation would lead to a slight decrease in milk production, but an improvement for functional traits, including all reproduction traits. In all cases, the estimated correlations are either low or modest. We conclude that

    Recently, several research groups have demonstrated that several haplotypes may cause embryonic loss in the homozygous state. Up to now, carriers of genetic disorders were often excluded from mating, resulting in a decrease of genetic gain and a reduced number of sires available for the breeding program. Ongoing research is very likely to identify additional genetic defects causing embryonic loss and calf mortality by genotyping a large proportion of the female cattle population and sequencing key ancestors. Hence, a clear demand is present to develop a method combining selection against recessive defects (e.g., Holstein haplotypes HH1-HH5) with selection for economically beneficial traits (e.g., polled) for mating decisions. Our proposed method is a genetic index that accounts for the allele frequencies in the population and the economic value of the genetic characteristic without excluding carriers from breeding schemes. Fertility phenotypes from routine genetic evaluations were used to determine the economic value per embryo lost. Previous research has shown that embryo loss caused by HH1 and HH2 occurs later than the loss for HH3, HH4, and HH5. Therefore, an economic value of € 97 was used against HH1 and HH2 and € 70 against HH3, HH4, and HH5. For polled, € 7 per polled calf was considered. Minor allele frequencies of the defects ranged between 0.8 and 3.3%. The polled allele has a frequency of 4.1% in the German Holstein population. A genomic breeding program was simulated to study the effect of changing the selection criteria from assortative mating based on breeding values to selecting the females using the genetic index. Selection for a genetic index on the female path is a useful method to control the allele frequencies by reducing undesirable alleles and simultaneously increasing economical beneficial characteristics maintaining most of the genetic gain in production and functional traits. Additionally, we applied the genetic index to real data and

    Along its contact with the Baltic Shield, the margin of the East European Platform reveals a well-developed, flooded terraced relief. The most striking and consistent set of escarpments at the contact of the Lower Palaeozoic calcareous and terrigenous rocks, known as the Baltic Klint (BK), extends from northwest of Russia to the Swedish island of Öland. Marine seismic reflection profiling in 1990-2004 revealed the central Baltic Sea Klint (BSK) section in detail and enabled comparison of its geology/geomorphology with a classical klint-section onshore, namely the North Estonian Klint (NEK). The conception of the BK onshore, which is based on the land-sea separating terraced relief in northern Estonia, is not fully applicable beneath the sea. Therefore, we consider that the BSK includes the entire terraced Cambrian outcrop. We suggest the term "Baltic Klint Complex" to include the well-terraced margin of the Ordovician limestone outcrop, which is weakly developed in Estonia. Because of a steady lithological framework of the bedrock layers across the southern slope of the Fennoscandian Shield, the central BSK in the western and the NEK in the eastern part of the Baltic Homocline have largely identical morphologies. The North Estonian Ordovician limestone plateau with the calcareous crest of the BK extends across the central Baltic Sea, whereas morphological changes/variations along the Klint base occur due to the east-westerly lithostratigraphic/thickness changes in the siliciclastic Cambrian sequence. The verge of the NEK, located some 30-50 m above sea level, starts to drop in altitude as its east-westerly course turns to northeast-southwest in western Estonia. Further westwards, the BK shifts gradually into southerly deepening (0.1-0.2°) layers as its crest drops to c. 150 m below sea level (b.s.l.) near Gotska Sandön. This course change is accompanied by a considerable decrease in thickness of the platform sedimentary cover, as below the central Baltic Sea the

    To examine non-cancer morbidity in the Estonian Chernobyl cleanup workers cohort compared with the population sample with special attention to radiation-related diseases and mental health disorders. Register-based cohort study. Estonia. An exposed cohort of 3680 men (cleanup workers) and an unexposed cohort of 7631 men (population sample) were followed from 2004 to 2012 through the Population Registry and Health Insurance Fund database. Morbidity in the exposed cohort compared with the unexposed controls was estimated in terms of rate ratio (RR) with 95% CIs using Poisson regression models. Elevated morbidity in the exposed cohort was found for diseases of the nervous system, digestive system, musculoskeletal system, ischaemic heart disease and for external causes. The most salient excess risk was observed for thyroid diseases (RR=1.69; 95% CI 1.38 to 2.07), intentional self-harm (RR=1.47; 95% CI 1.04 to 2.09) and selected alcohol-related diagnoses (RR=1.25; 95% CI 1.12 to 1.39). No increase in morbidity for stress reactions, depression, headaches or sleep disorders was detected. No obvious excess morbidity consistent with biological effects of radiation was seen in the exposed cohort, with the possible exception of benign thyroid diseases. Increased alcohol-induced morbidity may reflect alcohol abuse, and could underlie some of the higher morbidity rates. Mental disorders in the exposed cohort were probably under-reported. The future challenge will be to study mental and physical comorbidities in the Chernobyl cleanup workers cohort. Published by the BMJ Publishing Group Limited.

    Diet has health consequences, which makes knowing the psychological correlates of dietary habits important. Associations between dietary habits and personality traits were examined in a large sample of Estonians (N = 1,691) aged between 18 and 89 years. Dietary habits were measured using 11 items, which grouped into two factors reflecting (a) health aware and (b) traditional dietary patterns. The health aware diet factor was defined by eating more cereal and dairy products, fish, vegetables and fruits. The traditional diet factor was defined by eating more potatoes, meat and meat products, and bread. Personality was assessed by participants themselves and by people who knew them well. The questionnaire used was the NEO Personality Inventory-3, which measures the Five-Factor Model personality broad traits of Neuroticism, Extraversion, Openness, Agreeableness, and Conscientiousness, along with six facets for each trait. Gender, age and educational level were controlled for. Higher scores on the health aware diet factor were associated with lower Neuroticism, and higher Extraversion, Openness and Conscientiousness (effect sizes were modest: r = .11 to 0.17 in self-ratings, and r = .08 to 0.11 in informant-ratings, ps < 0.01 or lower). Higher scores on the traditional diet factor were related to lower levels of Openness (r = -0.14 and -0.13, p < .001, self- and informant-ratings, respectively). Endorsement of healthy and avoidance of traditional dietary items are associated with people's personality trait levels, especially higher Openness. The results may inform dietary interventions with respect to possible barriers to diet change.

    Nearly 2% of the male population of Estonia aged 20-39 years were sent to Chernobyl to assist in the cleanup activities after the reactor accident. A cohort of 4,833 cleanup workers was assembled based on multiple and independent sources of information. Information obtained from 3,704 responses to a detailed questionnaire indicated that 63% of the workers were sent to Chernobyl in 1986; 54% were of Estonian and 35% of Russian ethnicity; 72% were married, and 1,164 of their 5,392 children were conceived after the Chernobyl disaster. The workers were less educated than their counterparts than their counterparts in the general population of Estonia, and only 8.5% had attended university. Based on doses entered in workers records, the mean dose was 11 cGy, with only 1.4% over 25 cGy. Nearly 85% of the workers were sent as part of military training activities, and more than half spent in excess of 3 months in the Chernobyl area. Thirty-six percent of the workers reported having worked within the immediate vicinity of the accident site; 11.5% worked on the roofs near the damaged reactor, clearing the highly radioactive debris. The most commonly performed task was the removal and burial of topsoil (55% of the workers). Potassium iodide was given to over 18% of the men. The study design also incorporates biological indicators of exposure based on the glycophorin A mutational assay of red blood cells and chromosome translocation analyses of lymphocytes; record linkage with national cancer registry and mortality registry files to determine cancer incidence and cause-specific mortality; thyroid screening examinations with ultrasound and fine-needle biopsy; and cryopreserved white blood cells and plasma for future molecular studies. Comprehensive studies of Chernobyl cleanup workers have potential to provide a new information about cancer risks due to protracted exposures to ionizing radiation. 21 refs., 1 fig., 11 tabs

Los porcentajes de heterosis tomando como referencia la raza Holstein fueron: -45,20%, -21,50%, 6,25% y 5,35% en el mismo orden de las características anteriormente citadas. En general, los porcentajes de heterosis fueron menores a los reportados en la literatura. Se concluye que el F1 ha desempeñado un papel preponderante en el mejoramiento de la calidad de la leche en el Centro Paysandú, presentado porcentajes de heterosis medios para la calidad de la leche con referencia a la raza Holstein. Esto puede ser confirmado al analizar el porcentaje de grasa desde 1994, cuando parieron las primeras vacas F1, presentado coeficiente de regresión y correlación de 0,02 y 0,55 respectivamente. En la actualidad, el promedio para el porcentaje de grasa y proteína en el hato es de 3,45% y 3,03% respectivamente. Si sólo se tuviese la raza Holstein, estos porcentajes serían de 3,20% y 2,80%, significativamente menores.

    Full Text Available Any consideration of Estonian theatre from the point of view of biographical theatre needs to include the work of playwright and director Merle Karusoo. Productions based on various life narratives (diaries, letters, biographical interviews form the core of her work that can be defined as biographical or memory theatre. Her work has also been viewed within the context of community theatre or political theatre; Karusoo has herself referred to her work as sociological theatre. Life narratives have functioned in Karusoo’s productions as the basis for restoring oppressed or denied collective discourses of memory. Her productions emerged within the framework of the more general process of restoration of historical heritage and the rehabilitation of collective memory at the end of the 1980s and the beginning of the 1990s. Life story can be viewed as the essence of Merle Karusoo’s theatre. The personal in the life story in the production activates the emotional memory of the audience; for older generations such theatre facilitates a legitimisation of remembering one’s life story in entirety, and for younger generations it functions as a vehicle of collective, historical and national memory. The current article outlines the main stages of Karusoo’s biographical theatre, highlights major productions of each stage and provides an overview of their reception. Karusoo’s theatre dates back to 1980s. Productions based on life stories of the generations born in 1950s and 1960s, Meie elulood (Our Biographies and Kui ruumid on täis ...

    Full Text Available Estonian knowledge of history emanates from the fact that constituting an independent nation has for the most part been nothing but a utopia, and was a reality for a relatively short time. When it comes to selfidentification though, the expression ’a singing people’ is often used by the Estonians to describe themselves. Nostalgia for freedom is reflected in the Estonian culture of almost all periods and is carried on by the singing tradition, where patriotic songs emerge independent of different musical tastes within a particular generation and form an important part of a common Estonian repertoire. Patriotic songs occupy a central place in several fields of Estonian culture: besides music culture also in popular culture,and literary history – the works of poetry which have gained the most popularity are those which when put to music have been the most widely spread among the people. The main part of the most popular Estonian patriotic songs are choral songs from the national awakening at the end of the 19th century. Despite the national programmes aiming to wipe out ‘bourgeois nationalism’, they were sung at the song festivals in the Soviet era and were published in song books, expressing the people’s nostalgia for freedom lost. After the end of the Second World War, there was an attempt at launching a kind of patriotic new creation, where patriotism was merged with Soviet pathos; the aim was to show that the people’s utopia was in fact communism, but not a single one of those songs made it into the people’s common repertoire. Only the patriotic songs composed in the 1980s during the so-called new national awakening reached a popularity comparable to that of the old songs. The discourse on ’Estonianness’ and the shaping of a matching repertoire under imperial Russian rule took place under very different circumstances than its preservation and development in the second half of the 20th century under Soviet occupation, but

    Full Text Available Recession has sharply erected the question of tax burden and the optimal proportion of different kinds of taxes among the incomes of the budget. Indirect taxes and consumption taxes, which proportion is different according to different methodologies, dominate in Estonian state budget. The buoyancy of a tax system based on taxes of that kind is especially weak during the recession. The purpose of Estonian government’s economic policy during the highest peak of crisis was to keep the budget in balance. Instead of recovering economy the taxes were arisen and costs were reduced. The results of such a policy aren’t still clear. Difficulties concerning the incomes of budget have arisen the necessity for lifting taxes, which is possible as the tax burden is low now. But a sharp question of the optimal level of taxes is going to be raised. A formula for indirect tax optimum according to Ramsey taxes and Slutski decomposition has been proposed in the article

Attained product meets today’s market requirements: firstly as an export-meat category that meets Italian market requirements, since other markets are not well known, secondly, it can be used as a sport-tourist-recreation horse. It must be pointed out that all produced hybrids did not meet the needs of these two basic criteria. In spite of being potential slaughtery head with good utilization, each produced head can be, according to its exterial properties, used as a sporttourist animal that showed certain usable values and results proven by the experiment. The hybrids showed some hereditory draft horse properties shown on enclosed photos. In addition, exterier measures show that former knowledge on hybrids can respond the question of a horse raising on non-utilized pastures which they got used to very well. Thus these horses are able to be estimated by their body development just as our native draft Posavian type horse including possibility of using them as a sport-tourist-recreation horse.

    Ketosis is a prevalent periparturient metabolic disorder and we hypothesize that lipopolysaccharide (LPS) infiltration may play a key role in its etiology. Study objectives were to characterize biomarkers of inflammation during the transition period in healthy and clinically diagnosed ketotic cows. Cows were retrospectively categorized into one of two groups: healthy and clinically diagnosed ketotic. Two data sets were utilized; the first dataset (Study A) was obtained as a subset of cows (n=16) enrolled in a larger experiment conducted at the Iowa State University Dairy utilizing Holstein cows (8 healthy; 8 ketotic), and the second dataset (Study B; 22 healthy; 22 ketotic) was obtained from a commercial farm. For both experiments, blood samples were collected prior to and following calving. Ketotic cows in both studies had reduced milk production compared to healthy cows (P6 fold and ~4 fold; P=0.04 and P=0.03), and lipopolysaccharide binding protein (66 and 45%; Pketosis in transition dairy cows.

    Trials to determine the onset of post-partum (pp) ovarian activity in a Holstein herd were carried out in 1985 and repeated during the same time of the year in 1987. In each, 20 recently calved adult cows and first-calf heifers were randomly selected and sampled for milk progesterone (MP 4 ) determination twice a week between days 10 and 90 pp. Climatic conditions and availability of high quality fodder were better in 1987 than 1985. Results showed differences both in pregnancy rate (40% vs. 65%), as well as in the percentage of anoestrous cows (60% vs. 15%) between 1985 and 1987, respectively. In the second trial, not all cows in physiological oestrus (according to MP 4 measurements) were identified in heat by observation of behavioural signs. It was concluded that nutritional levels greatly influence the reproductive efficiency of the herd on this farm, and that poor oestrus detection was a further contributory factor. Another trial conducted on a dairy herd in order to compare the efficiency of oestrus synchronization by PGF 2α with manual enucleation of the corpus luteum (CL) showed no differences between treatment groups. Ovarian palpation to assess the presence of a CL was accurate in 69% of cases while the use of MP 4 estimations proved to be 100% efficent. (author). 13 refs, 1 fig., 2 tabs

    The objective was to examine uterine artery hemodynamics and maternal serum profiles in pregnant heifers supplemented with dietary melatonin (MEL) or no supplementation (CON). In addition, melatonin receptor-mediated responses in steroid metabolism were examined using a bovine endometrial epithelial culture system. Twenty singleton pregnant Holstein heifers were supplemented with 20 mg of melatonin (n = 10) or no melatonin supplementation (control; n = 10) from days 190 to 262 of gestation. Maternal measurements were recorded on days 180 (baseline), 210, 240, and 262 of gestation. Total uterine blood flow was increased by 25% in the MEL-treated heifers compared with the CON. Concentrations of progesterone were decreased in MEL vs CON heifers. Total serum antioxidant capacity was increased by 43% in MEL-treated heifers when compared with CON. Activity of cytochrome P450 1A, 2C, and superoxide dismutase was increased in bovine endometrial epithelial cells treated with melatonin, whereas the melatonin receptor antagonist, luzindole, negated the increase in cytochrome P450 2C activity. Moreover, estradiol or progesterone treatment altered bovine uterine melatonin receptor expression, which could potentiate the melatonin-mediated responses during late gestation. The observed increase in total uterine blood flow during melatonin supplementation could be related to its antioxidant properties. Compromised pregnancies are typically accompanied by increased oxidative stress; therefore, melatonin could serve as a therapeutic supplementation strategy. This could lead to further fetal programming implications in conjunction with offspring growth and development postnatally. Copyright © 2016 Elsevier Inc. All rights reserved.

    The objective of this study was to investigate the relationship between temperature-humidity index (THI) and rumination time (RT) in order to possibly exploit it as a useful tool for animal welfare improvement. During summer 2015 (1 June to 31 August), data from an Italian Holstein dairy farm located in the North of Italy were collected along with environmental data (i.e. ambient temperature and relative humidity) recorded with a weather station installed inside the barn. Rumination data were collected through the Heatime® HR system (SCR Engineers Ltd., Hadarim, Netanya, Israel), an automatic system composed of a neck collar with a Tag that records the RT and activity of each cow. A significant negative correlation was observed between RT and THI. Mixed linear models were fitted, including animal and test day as random effects, and parity, milk production level and date of last calving as fixed effects. A statistically significant effect of THI on RT was identified, with RT decreasing as THI increased.

    2012-06-01

    Existing variation in energy efficiency and its relationship with milk yield and milk composition, body weight and body condition, feed intake, and energy status was studied in primiparous Nordic Red dairy cattle with data including 3,752 weekly records from 145 cows. Energy efficiency was defined as energy conversion efficiency (ECE) and as residual energy intake (REI) estimated based on Finnish feeding standards (REI₁) or from the current data (REI₂). The results indicated true phenotypic variation in energy efficiency of the cows. The proportion of total variance due to the animal was 0.35 for REI₁, 0.30 for REI₂, and 0.50 for ECE. The high efficiency based on ECE was associated with increased mobilization of body reserves (r = -0.50) and decreased dry matter intake (r = -0.51). With REI as an energy efficiency measure, the increased efficiency was associated with a large decrease in feed intake (REI₁: r = 0.60; REI2: r = 0.74) without any effect on body weight change (REI₁: r = 0.13; REI2: r = 0.00). Increased efficiency based on ECE and REI₁ was associated with increased milk yield (ECE: r = 0.58; REI₁: r = -0.41). A clear effect of stage of lactation on REI was found, which could be caused by true differences in utilization of metabolizable energy during lactation. However, it might also be related, in part, to the lack of knowledge of the composition of body weight change in the beginning of lactation. Copyright © 2012 American Dairy Science Association.

    Full Text Available The aim of the study was to determine the mechanical and geometric properties as well as bone tissue density of long bones in primiparous and multiparous dams of minks supplemented with β-hydroxy β-methylbutyrate (HMB and/or 2-oxoketoglutarate (2-Ox during gestation. Powdered 2-Ox was given at the daily dosage of 0.4 g/kg b.w. separately or simultaneously with HMB, which was administered at the daily dosage of 0.02 g/kg b.w. The study demonstrates for the first time that administration of 2-Ox and/or HMB to dams markedly influences bone tissue density and the mechanical and geometrical properties of mother`s bones in minks. Moreover, it was demonstrated that the supplementation was more effective in the thoracic limb, which was comprehensively used in contrast to the pelvic limb. The mechanical parameters and bone tissue density significantly increased in the humerus in multiparous minks. Only such diet may provide satisfactory production results in the animals. Nutritional deficiencies occurring during pregnancies may trigger body`s own reserves to cover the bone mass increase in developing foetuses and support milk production. This can prevent regeneration of dams’ organisms, which negatively affects their reproductive performance. 2-Ox or HMB may be regarded as a protective metabolite when administered orally to minks, counteracting the negative influences of pregnancy and lactation periods on bones condition. Both simultaneous treatment with 2-Ox and HMB and their separate administration were equally effective.

    Full Text Available This study aimed to evaluate milk composition and metabolic profile of Holstein cows at different calving orders in the beginning, middle, and end of lactation. One hundred ten Holstein cows were housed in a free stall system receiving the same diet and were grouped according to calving order (first, second, third, and fourth calving and days in milk (DIM: early (1-90 DIM, middle (91-180 DIM, and end of lactation (over 181 DIM for comparing milk yield, milk composition, and blood metabolic profile between the calving orders within the same lactation period. These parameters were also evaluated between lactation periods of the cows in different calving orders. The calving order, in any lactation stage, had no influence on milk yield per day and blood biochemical profile of Holstein cows receiving the same diet. However, calving order in all stages of lactation influenced milk composition. The first, second, third, and fourth calving order had no effect on the blood biochemical profile of Holstein cows, in any lactation stage. On the other hand, the different stages of lactation influenced milk yield and milk composition of Holstein cows.

    2012-04-01

    Full Text Available In this article I examine the development of Estonian autobiographical writing from its first manifestations to published memoirs, and the development of life writing and its diversification. The beginnings of life writing can be traced back to Estonian folk song and Estonian incidental poetry. The Moravian Brethren movement in Estonia in the 18th century promoted the spread of canonical autobiography. The Moravian Brethren offered alternative opportunities for self-realisation for Estonians who were serfs, and were therefore popular with the people. The practice of the Moravian Brethren made use of retelling and writing about the life of the congregation members, which sometimes became suitable biographies in print, especially stories of awakening. Several manuscript biographies have survived from the Brethren times, such as the biographies of Mäletu Jaan and Mihkel Sarapuu. In addition to the history of the Moravian Brethren movement, these biographies give information about the educational situation and living conditions of the people of the time. The Estonian life writing tradition emerged within the reigning Baltic German cultural space thanks to the Estophiles among the Baltic Germans (J. H. Rosenplänter and the first Estonian men of letters; from the early 19th century we have the diary by Rosenplänter, an estophile pastor from Pärnu, and the diary by the Estonian poet, the then-student Kristjan Jaak Peterson, both in the Estonian language. Johann Voldemar Jannsen, the founder of Estonian-language journalism, kept a diary in the German language for a longer period of time; it was usual that the first Estonian intellectuals (Lilli Suburg, and others in the late 19th century wrote in German. Admittedly, the first Estonian-language life history was written by a forward-looking 19th century peasant named Märt Mitt (1833-1912, who was conscious of himself as a historical subject and gave his memoirs, begun in the 1880s, a memorable title

    Two experiments evaluated milk production, serum progesterone and insulin, and reproductive performance of lactating Holstein cows receiving or not receiving Ca salts of polyunsaturated fatty acids (PUFA), or receiving Ca salts of PUFA at different daily frequencies. In experiment 1, 1,125 cows randomly distributed in 10 freestall barns were enrolled. Barns were assigned randomly to receive a high-concentrate diet containing (PF) or not containing (control, CON) 1.1% (dry matter basis) Ca salts of PUFA. Diets were offered 6 times daily, whereas the Ca salts of PUFA were included in the PF treatment in the first feeding of the day. In experiment 2, 1,572 cows were randomly distributed in 10 freestall barns, which were assigned randomly to receive a diet similar to PF, but with Ca salts of PUFA included only in the first feeding of the day (PF1X), or equally distributed across all 6 feedings (PF6X). During both experiments, cows were artificially inseminated 12 h after the onset of estrus. Once per month, cows that did not conceive to artificial insemination were assigned to a fixed-time embryo transfer protocol. Pregnancy was determined via transrectal ultrasonography 28 and 60 d after expected ovulation. Pregnancy loss was considered in cows that were pregnant on d 28 but nonpregnant on d 60. During both experiments, feed intake, milk yield, and milk protein and fat content were recorded weekly. Blood samples were collected concurrently with embryo transfer. During experiment 1, feed intake was similar between treatments. Compared with CON, PF cows had greater milk yield (37.8 vs. 35.3 kg/d), and reduced milk fat content (3.41 vs. 3.55%). However, PF cows had reduced pregnancy losses per service compared with CON (12.6 vs. 18.3%). Serum progesterone was greater and serum insulin tended to be greater in primiparous cows receiving PF compared with CON cohorts (4.50 vs. 3.67 ng of progesterone/mL, and 10.4 vs. 7.5 µUI of insulin/mL). During experiment 2, no treatment

    Conformation traits have been widely explored in dairy cattle evaluation, being a part of the total merit index for Holstein cows in different countries. They have been used as a way to access the cow’s condition in general, based on its body features. Lots of studies have analyzed the relationship...... traits in Holstein cows: height (H), body depth (BD), chest width (CW), dairy character (DC) and body condition score (BCS). Data was collected on 1114 Holstein cows from 11 commercial herds in Denmark. Methane emission was measured during milking in milking robots, and then quantifed using information...... between conformation traits and other traits of interest in dairy cattle, such as fertility, longevity and feed effciency, but little is known about how methane emissions correlate with conformation traits. Therefore, our goal was to evaluate the genetic correlations between methane and six conformation...

    Some individuals have expressed concern about estrogens in food because of their potential to promote growth of estrogen-sensitive human cancer cells. Researchers have reported concentrations of estrogen in milk but few whole milk samples have been analyzed. Because estrogen associates with the fat phase of milk, the analysis of whole milk is an important consideration. The objectives of this study, therefore, were to quantify 17beta-estradiol (E2) in whole milk from dairy cows and to determine whether E2 concentrations in milk from cows in the second half of pregnancy were greater than that in milk from cows in the first half of pregnancy or in nonpregnant cows. Milk samples and weights were collected during a single morning milking from 206 Holstein cows. Triplicate samples were collected and 2 samples were analyzed for fat, protein, lactose, and somatic cell counts (SCC); 1 sample was homogenized and analyzed for E2. The homogenized whole milk (3 mL) was extracted twice with ethyl acetate and once with methanol. The extract was reconstituted in benzene:methanol (9:1, vol/vol) and run over a Sephadex LH-20 column to separate E2 from cholesterol and estrone before quantification using radioimmunoassay. Cows were classified as not pregnant (NP, n = 138), early pregnant (EP, 1 to 140 d pregnant, n = 47), or midpregnant (MP, 141 to 210 d pregnant, n = 21) at the time of milk sampling based on herd health records. Mean E2 concentration in whole milk was 1.4 +/- 0.2 pg/mL and ranged from nondetectable to 22.9 pg/mL. Milk E2 concentrations averaged 1.3, 0.9, and 3.0 pg/mL for NP, EP, and MP cows, respectively. Milk E2 concentrations for MP cows were greater and differed from those of NP and EP cows. Milk composition was normal for a Holstein herd in that log SCC values and percentages of fat, protein, and lactose averaged 4.9, 3.5, 3.1, and 4.8, respectively. Estradiol concentration was significantly correlated (r = 0.20) with percentage fat in milk. Mean milk yield was

    Full Text Available The Estonian model of language planning and policy, which has been serving the development and protection of the Estonian language in its current form since 2004, is one of the most successful of such strategies in Europe. It owes it success to the broad social and scientific consensus reached in questions of language policy, regardless of changes in government. The Development Plan of the Estonian Language divides Estonian language planning and policy into three parts: status planning, corpus planning and prestige planning. Name management is a part of corpus planning, although certain aspects are also connected to legal and prestige planning. Name management strategies are present in all components of the Estonian model of language planning and policy, as linguistically appropriate name use is not only a socio-cultural, but economic question, as informative and easy to understand names contribute to measurable economic advantages. The paper mainly demonstrates the dilemmas and answers of Estonian name management through examples from personal name giving practices, but questions concerning the problems of name use in a multicultural environment and the difficulties of place name and firm name management are also discussed.

    Regional analyses of atmospheric conditions that may cause flooding of important transport infrastructure (railway tracks, highways/roads, rivers/channels) and subsequent adaptation measures are part of topic 1 of the network of experts initiated by the German Federal Ministry of Transport and Digital Infrastructure (BMVI). As an example case study, the December 2014 flood in Schleswig-Holstein, Germany, was investigated. Atmospheric conditions at the onset of the flood event are described and evaluated with respect to the general weather circulation, initial wetness, and event precipitation. Persistent, predominantly westerly general weather circulations (GWCs) directed several low-pressure systems over the North Sea to Schleswig-Holstein during December 2014, accompanied by prolonged rainfall and finally a strong precipitation event in southern Schleswig-Holstein, causing several inland gauges to exceed their, by then maximum, water levels. Results show that the antecedent precipitation index (API) is able to reflect the soil moisture conditions and, in combination with the maximum 3-day precipitation sum (R3d), to capture the two main drivers finally leading to the flood: (1) the initial wetness of north-western Schleswig-Holstein and (2) strong event precipitation in southern and eastern Schleswig-Holstein from 21 to 23 December; at the same time, both indices exceeded their respective 5-year return periods. Further, trend analyses show that both API and R3d have been increasing during recent years, while regional patterns match the north-eastward shift of cyclone pathways, leading to a higher risk of flooding in Schleswig-Holstein. Within the network of experts, investigations of these and further indices/drivers for earth system changes (e.g. wind surge and sea level rise) derived from observations, reanalyses, and regional climate model data are planned for all German coastal areas. Results can be expected to lead to improved adaptation measures to floods

    To evaluate the effect of sephadex column filtration technique on semen quality of five Holstein bulls and five Egyptian buffalo bulls. Semen was collected biweekly from each eight weeks. Immediately after collection, semen was extended (37degree C) and filtered using sephadex column-filtration technique. Semen was evaluated for physical semen characteristics including, percentages of sperm motility, live sperm and sperm abnormality as well as sperm cell concentration pre-and post-filtration. Results show that among all physical semen characteristics, only ejaculate semen volume was significantly (P<0.001) higher in Holstein than buffalo bulls, but motility, livability, abnormality, sperm concentration and sperm with intact acrosome did not differ between both species. As a result of filtration, sperm motility and livability increased (P<0.05) by 16.4 and 11.8% in Holstein and by 16.9 and 10.1% in buffalo semen, respectively. Sperm abnormality and concentration reduced (P<0.05) by 2.6 and 3.3% in Holstein and by 2.4 and 3.5% in buffalo semen, respectively. Improvements of live sperm and the reduction in sperm concentration (proportional to the pre-filtration value) were better (P<0.05) in Holstein than buffalo semen (15.5% and %52.4 vs. 13.2 and -49.3%, respectively). Improvement of motility and abnormality did not differ in Holstein (25.4 and %57.8) and buffalo semen (26.6 and ,(%54.5respectively. The present results indicate that using sephadex column filter technique has beneficial effects on improving quality of spermatozoa in both species. (author)

    We investigate the effects of local vibrational excitations in the nonsymmetrized current noise S (ω ) of a nanojunction. For this purpose, we analyze a simple model—the Holstein model—in which the junction is described by a single electronic level that is coupled to two metallic leads and to a single vibrational mode. Using the Keldysh Green's function technique, we calculate the nonsymmetrized current noise to the leading order in the charge-vibration interaction. For the noise associated to the latter, we identify distinct terms corresponding to the mean-field noise and the vertex correction. The mean-field result can be further divided into an elastic correction to the noise and in an inelastic correction, the second one being related to energy exchange with the vibration. To illustrate the general behavior of the noise induced by the charge-vibration interaction, we consider two limit cases. In the first case, we assume a strong coupling of the dot to the leads with an energy-independent transmission, whereas in the second case we assume a weak tunneling coupling between the dot and the leads such that the transport occurs through a sharp resonant level. We find that the noise associated to the vibration-charge interaction shows a complex pattern as a function of the frequency ω and of the transmission function or of the dot's energy level. Several transitions from enhancement to suppression of the noise occurs in different regions, which are determined, in particular, by the vibrational frequency. Remarkably, in the regime of an energy-independent transmission, the zero-order elastic noise vanishes at perfect transmission and at positive frequency, whereas the noise related to the charge-vibration interaction remains finite, enabling the analysis of the pure vibrational-induced current noise.

    Full Text Available Assessing the metabolic profile based on the concept that the laboratory measurement of certain circulating components is a tool to evaluate metabolic status of dairy cows. Veterinarian also can evaluate the energy input-output relationships by assessing the metabolic profile to prevent and control of negative energy balance, metabolic disorders and nutritional insufficiencies. In the present study, 25 multiparous Holstein dairy cows were divided to 5 equal groups containing early, mid and late lactation, and far-off and close-up dry. Blood samples were collected from all cows through jugular venipuncture and sera were evaluated for glucose, insulin, β-hydroxybutyric acid (BHBA, non-esterified fatty acid (NEFA, cholesterol, triglyceride (TG, high, low and very low density lipoproteins (HDL, LDL and VLDL. Insulin levels in mid lactation and close-up dry cows were significantly higher than other groups (P<0.05 and the lowest insulin concentration was detected in far-off dry group. Serum concentrations of NEFA and BHBA in early and mid-lactation and close-up dry cows were significantly higher than late lactation and far-off dry animals (P<0.05. Baseline levels of cholesterol in mid and late lactation were significantly higher than other groups. The level of LDL in mid lactation cows was higher than others significantly, and its value in far-off dry cows was significantly lower than other group (P<0.05. It may be concluded that the detected changes among different groups induce commonly by negative energy balance, lactogenesis and fetal growth in each state. The presented metabolic profile can be considered as a tool to assess the energy balance in dairy cows at different physiologic states. It can be used to evaluate the metabolic situations of herd and manage the metabolic and production disorders.

    Reproductive performance and nutritional status were assessed in Holstein cows from two dairy herds in Sao Paulo State, Brazil. In the first herd (good management, G), concentrate was fed individually to cows, complete records were kept, veterinary services were provided as necessary and the standard of husbandry practices was good. In the second herd (fair management, F), veterinary services were used only occasionally, the concentrate fed was divided equally among lactating cows and the standard of husbandry practices was only fair. Haemoglobin, haematocrit, glucose, total protein and phosphorus were measured in blood collected at various times after calving. There were no statistical differences between the blood parameters in the two herds except for inorganic phosphorus which differed significantly between farms (P < 0.01). Only plasma glucose had a significant (P < 0.01) effect on the time required by the animals to initiate post-partum ovarian activity. The proportion of cows ovulating by day 60 was 75% in herd G versus 53% in herd F (P < 0.01); by day 100 the values were 82% in herd G and 70% in herd F (P < 0.01). Calving intervals were 12.7 and 13.2 months for herds G and F respectively, suggesting comparable reproductive efficiency. However, only 1 of the 28 cows in herd G was open more than 365 days after calving, as opposed to 5 of the 30 cows in herd F. When a value of 365 open days was given for these non-pregnant cows, the average days open for the herds were then 123 and 154 days for herds G and F respectively, indicating a decided production advantage in favour of the better managed herd.

    Milk yield is an important trait in dairy industry; thus, information regarding this phenotype is essential to measure the productivity of a farm. Total milk yield in one lactation period was often predicted using information from samples collected within certain time intervals. The rate of change of milk production between two-time intervals is defined as persistency. This article aims to estimate the persistency of milk yield between lactation 1, 2 and 3 in Indonesian Friesian Holstein (IFH) cows. Data was collected from Limpakuwus stable, Baturraden Dairy Cattle Breeding Centre, Central Java Indonesia. Records were obtained from cows which started lactating on 2013 until the end of third lactation around the beginning of 2016. Milk yield from the first (L1), second (L2) and third (L3) lactations of 21 cows were recorded in kilograms. Samples were collected in 30 days basis interval started from the 10th day of lactation up to the 10th month. In this population, the cows first calving was around February – April 2013; while the second and third calving occurred all over the relevant year. The mean of milk yield for L1, L2 and L3 were 17.77±3.70, 16.09±5.17 and 13.73±4.02 Kg respectively. The peak of milk yields was achieved at the second month of the lactation for L1, L2 and L3. The persistency from the second to the tenth test days were 97, 93 and 94% for L1, L2 and L3, respectively. Milk yield persistency is representing ability of cow in maintain milk production after peak during lactation period. The more persistent shows better performance of dairy cattle as well as farm management. For that, persistency value could be used as valuable information in evaluating the management in Indonesian dairy farms.

    High-yielding dairy cattle are susceptible to ketosis, a metabolic disease that negatively affects the health, fertility, and milk production of the cow. Interest in breeding for more robust dairy cattle with improved resistance to disease is global; however, genetic evaluations for ketosis would benefit from the additional information provided by genetic markers. Candidate genes that are proposed to have a biological role in the pathogenesis of ketosis were investigated in silico and a custom panel of 998 putative single nucleotide polymorphism (SNP) markers was developed. The objective of this study was to test the associations of these new markers with deregressed estimated breeding values (EBV) for ketosis. A sample of 653 Canadian Holstein cows that had been previously genotyped with a medium-density SNP chip were regenotyped with the custom panel. The EBV for ketosis in first and later lactations were obtained for each animal and deregressed for use as pseudo-phenotypes for association analyses. Results of the mixed inheritance model for single SNP association analyses suggested 15 markers in 6 unique candidate genes were associated with the studied trait. Genes encoding proteins involved in metabolic processes, including the synthesis and degradation of fatty acids and ketone bodies, gluconeogenesis, lipid mobilization, and the citric acid cycle, were identified to contain SNP associated with ketosis resistance. This work confirmed the presence of previously described quantitative trait loci for dairy cattle, suggested novel markers for ketosis-resistance, and provided insight into the underlying biology of this disease.

    2011-01-01

    Full Text Available This paper describes paratuberculosis in an isolated breeding herd of 25 high-yield dairy cows of the Red Holstein breed. The animals were examined clinically and then given the test for ldelayed type hypersensitivity and their blood serum was examined for the presence of specific antibodies against Mycobacterium avium subsp. paratuberculosis (Map. The clinical examination revealed that two cows exhibited symptoms of the disease that indicated an advanced stage of paratuberculosis. The following parameters were examined in the blood of the cows that showed clinical signs of the disease: leukocytes and erythrocytes count, concentrations of total proteins, albumin, iron, sodium, potassium, and activity of creatine kinase. The analysis of the red blood cell count revealed certain digressions that indicated the existence of hypochromic microcytic anaemia. The number of leukocytes was within the physiological values, but the neutrophil-lymphocyte ratio was disrupted and stood at almost 1:1. The results of the biochemical analyses of the blood serum of diseased cows indicated hypoproteinaemia, hypoalbuminaemia, hypoferremia, hyposodiumaemia, hypokalemia, and increased activities of creatine kinase enzymes. A suspect reaction on the site of application of avian tuberculin was determined in two animals. Animals with clinical signs of the disease reacted negative to the test of delayed type hypersensitivity. The presence of specific antibodies against the cause of paratuberculosis was proven in four animals (16%, including two animals with clinical signs of the disease and one that had a suspect reaction on the site of application of avian tuberculin. Furthermore, one animal that died exhibited macroscopic and microscopic changes regarding the intensity and distribution of lesions, the type of cellular infiltrate, and the number of present acidresistent bacteria, and the changes were characterized as diffuse changes of multibacillary type.

    GNSS permanent station network in Estonia (ESTREF) was established already in 2007. In 2014-15 extensive reconstruction of ESTREF was carried out, including the establishment of 18 new stations, change of the hardware in CORS stations as well as establishing GNSS-RTK service for the whole Estonia. For GNSS-RTK service one needs precise coordinates in well-defined reference frame, i.e., ETRS89. For long time stability of stations and time-series analysis the re-processing of Estonian CORS data is ongoing. We re-process data from 2007 until 2015 with program Bernese GNSS 5.2 (Dach, 2015). For the set of ESTREF stations established in 2007, we perform as well computations with GIPSY 6.4 software (Ries et al., 2015). In the computations daily GPS-only solution was used. For precise orbits, final products from CODE (CODE analysis centre at the Astronomical Institute of the University of Bern) and JPL (Jet Propulsion Laboratory) for Bernese and GIPSY solutions were used, respectively. The cut-off angle was set to 10 degrees in order to avoid near-field multipath influence. In GIPSY, precise point positioning method with fixing ambiguities was used. Bernese calculations were performed based on double difference processing. Antenna phase centers were modelled based on igs08.atx and epnc_08.atx files. Vienna mapping function was used for mapping tropospheric delays. For the GIPSY solution, the higher order ionospheric term was modelled based on IRI-2012b model. For the Bernese solution higher order ionospheric term was neglected. FES2004 ocean tide loading model was used for the both computation strategies. As a result, two solutions using different scientific GNSS computation programs were obtained. The results from Bernese and GIPSY solutions were compared, using station repeatability values, RMS and coordinate differences.

    An integrated system of nested 2D and 3D hydrodynamic models together with real time forcing data asquisition is designed and set up in pre-operational mode in the Gulf of Finland and Gulf of Riga, the Baltic Sea. Along the Estonian coast, implicit time-stepping 3D models are used in the deep bays and 2D models in the shallow bays with ca 200 m horizontal grid step. Specific model setups have been verified by in situ current measurements. Optimum configuration of initial parameters has been found for certain critical locations, usually ports, oil terminals, etc. Operational system in- tegrates also section of historical database of most important hydrologic parameters in the region, allowing use of certain statistical analysis and proper setup of initial conditions for oceanographic models. There is large variety of applications for such model system, ranging from environmental impact assessment at local coastal sea pol- lution problems to forecast of offshore blue algal blooms. Most probable risk factor in the coastal sea engineering is oil pollution, therefore current operational model sys- tem has direct custom oriented output the oil spill forecast for critical locations. Oil spill module of the operational system consist the automatic weather and hydromet- ric station (distributed in real time to internet) and prognostic model of sea surface currents. System is run using last 48 hour wind data and wind forecast and estimates probable oil deposition areas on the shoreline under certain weather conditions. Cal- culated evolution of oil pollution has been compared with some real accidents in the past and there was found good agreement between model and measurements. Graphi- cal user interface of oil spill model is currently installed at location of port authorities (eg. Muuga port), so in case of accidents it could be used in real time supporting the rescue operations. In 2000 current pre-operational oceanographic model system has been sucessfully used to

    Full Text Available The objective was to evaluate the effect of the interaction of diet density in the rearing phase×diet density in the reproductive phase on carcass composition, pregnancy rate, and litter performance of primiparous rabbit does. The experiment followed a 2×2×2 factorial (2 seasons, 2 diet densities in the rearing phase and 2 diet densities in reproductive phase, that is, from mating to weaning of the first litter. The reference diet (RD contained 184 g/kg of crude protein (CP, 165 g/kg of acid detergent fibre (ADF and 10.5 MJ/kg of digestible energy (DE. The low-density diet (LD had 147 g/kg of CP, 24 g/kg of ADF and 8.4 MJ/kg of DE. The treatments were applied from 70 d of age until weaning of the first litter at 35 d of age. Ninety-six females from the Botucatu Genetic Group (24 females/experimental group were mated at 142 d of age. On day 12 of gestation, 23 does were slaughtered to evaluate weights of carcass, organs and dissectible fat, and embryo implantation rate. No effects of diet density in the rearing or in the reproductive phases were detected on feed intake of does during the reproductive phase. Does fed LD during the rearing phase showed lower body weight at mating (3574±47 vs. 3866±43 g, P=0.0001 and during most of the reproductive phase, but they lost less weight in the peripartum. Perirenal fat was lighter in these does (72.8±10.0 vs. 102.1±9.6 g, P=0.048 and they showed a lower pregnancy rate (76.1 vs. 91.7%, P=0.045. The does fed RD in the reproductive phase were heavier during this phase (4055±40 g vs. 3887±41 g, P=0.0044. The does fed LD in rearing phase and RD in the reproductive phase showed larger litters at weaning, due to decreased kit mortality, than those fed RD in both phases (6.16±0.47 vs. 3.93±0.71, P=0.0361. Litters were lighter at weaning when LD was fed in the reproductive phase (3582±201 vs. 4733±187, P<0.0001. Feeding a low-density diet during the rearing phase and a reference diet during the

    Full Text Available Abstract Background Universal interventions to prevent postnatal mental disorders in women have had limited success, perhaps because they were insufficiently theorised, not gender-informed and overlooked relevant risk factors. This study aimed to determine whether an innovative brief psycho-educational program for mothers, fathers and first newborns, which addressed salient learning needs about infant behaviour management and adjustment tasks in the intimate partner relationship, prevented postpartum mental health problems in primiparous women. Methods A before and after controlled study was conducted in primary care in seven local government areas in Victoria, Australia. English-speaking couples with one-week old infants were invited consecutively to participate by the maternal and child health nurse at the universal first home visit. Two groups were recruited and followed sequentially: both completed telephone interviews at four weeks and six months postpartum and received standard health care. Intervention group participants were also invited to attend a half-day program with up to five couples and one month old infants, facilitated by trained, supervised nurses. The main outcome was any Composite International Diagnostic Interview (CIDI diagnosis of Depression or Anxiety or Adjustment Disorder with Depressed Mood, Anxiety, or Mixed Anxiety and Depressed Mood in the first six months postpartum. Factors associated with the outcome were established by logistic regression controlling for potential confounders and analysis was by intention to treat. Results In total 399/646 (62% women were recruited; 210 received only standard care and 189 were also offered the intervention; 364 (91% were retained at follow up six months postpartum. In women without a psychiatric history (232/364; 64%, 36/125 (29% were diagnosed with Depression or Anxiety or Adjustment Disorder with Depressed Mood, Anxiety, or Mixed Anxiety and Depressed Mood in the control group

    Holstein (HH), Jersey (JJ), and crosses of these breeds were mated to HH or JJ bulls to form purebreds, reciprocal crosses, backcrosses, and other crosses in a rotational mating system. The herd was located at the Center for Environmental Farming Systems in Goldsboro, North Carolina. Data for calf birth weight (CBW), calving ease (0 for unassisted, n=1,135, and 1 for assisted, n=96), and neonatal calf mortality (0 for alive, n=1,150, and 1 for abortions recorded after mid-gestation, stillborn, and dead within 48 h, n=81) of calves (n=1,231) were recorded over 9 calving seasons from 2003 through 2011. Gestation length (GL) was calculated as the number of days from last insemination to calving. Linear mixed models for CBW and GL included fixed effects of sex, parity (first vs. later parities), twin status, and 6 genetic groups: HH, JJ, reciprocal F(1) crosses (HJ, JH), crosses >50% Holsteins (HX) and crosses >50% Jerseys (JX), where sire breed is listed first. The CBW model also included GL as a covariate. Logistic regression for calving ease and neonatal calf mortality included fixed effects of sex, parity, and genetic group. Genetic groups were replaced by linear regression using percentage of HH genes as coefficients on the above models and included as covariates to determine various genetic effects. Year and dam were included as random effects in all models. Female calves (27.57±0.54 kg), twins (26.39±1.0 kg), and calves born to first-parity cows (27.67±0.56 kg) had lower CBW than respective male calves (29.53±0.53 kg), single births (30.71±0.19 kg), or calves born to multiparous cows (29.43±0.52 kg). Differences in genetic groups were observed for CBW and GL. Increased HH percentage in the calf increased CBW (+9.3±0.57 kg for HH vs. JJ calves), and increased HH percentage in the dams increased CBW (+1.71±0.53 kg for calves from HH dams vs. JJ dams); JH calves weighed 1.33 kg more than reciprocal HJ calves. Shorter GL was observed for twin births (272.6

    Within the countries surrounding the Baltic Sea, north-eastern Estonia is among the most polluted areas. Emissions from the oil-shale power plants produce air pollution problems both locally and on a larger scale. In the atmosphere, pollutants mix and convert. Consequently, the particles deposited due to the use of oil-shale can have various chemical compositions. From the point of view of air chemistry, ecological effects and air pollution modelling, knowledge of the chemical composition of the deposited particles can be of great value. The aim of this work was to study the chemical composition of single anthropogenic particles occurring on needle surfaces in north-eastern Estonia and Southern Finland close to the Estonian oil-shale power plants. For the purpose, scanning electron microscopical microanalysis was used

    Full Text Available The second larger Estonian R&D and Innovation Strategy ‘Knowledge-based Estonia 2007-2013’ is aimed at continuing the advancement of research and development efforts towards an innovative knowledge-based society and economic system in Estonia. Fostering of knowledge-based high-tech industries is seen as paramount for retaining country’s competitive advantage. However, the mid-term evaluations indicate that several goals of the strategy might not be achievable by 2013. In fact, the policy measures have been much more successful in developing scientific research, as indicated by increased international publication, number of patents, and number of researchers and engineers. The advances in development of high-tech products and services through innovations are noticeable but less prominent. The purpose of this study is to suggest the role for demand-side innovation policies in helping to advance commercial development and innovation

  2. Iseseisvusdeklaratsioonid 1776–1918. The Estonian Declaration of Sovereignty: An Example of the Civilizing Force of Hypocrisy

    Directory of Open Access Journals (Sweden)

    Hent Kalmo

    2012-06-01

    Full Text Available Sovereignty has been characterised as a form of “organized hypocrisy”, a system governed by a set of rules that are generally recognised as binding and yet are continually infringed upon by the most powerful actors. This idea can be extended to analyse the role of sovereignty within the Soviet Union. The Soviet Union was nominally governed by a Constitution which endowed the Union Republics with the right of secession, but there was no realistic possibility of exercising this right. One should not rush to conclude, however, that the actual wording of the Soviet Constitution of 1977 was entirely without relevance. As Jon Elster has argued, hypocrisy can have a “civilizing force” when the need to appear impartial and to retain public credibility forces actors to choose a strategy they would not choose otherwise. A good example of this kind of argumentative constraint is offered by the dilemma faced by the Soviet leadership after the mid-1980s, as it became reluctant to use military force to suppress independence movements within the Baltic States while, at the same time, promising to give more weight to the Soviet Constitution and respect the “sovereignty” of the Union Republics. In this setting, the ambiguity of the word “sovereignty” could be played upon by a whole gamut of political movements in order to further their agenda, from local communists eager to expand their autonomy within the Soviet system to those making an explicit bid for the restoration of independence. Significant legal and political changes could be justified as mere conclusions from the constitutionally recognised status of the Union Republics – a strategy which was all the more effective as Moscow struggled to formulate an alternative line of constitutional interpretation that could be used to counter the Baltic claims. This exchange of opinions escalated into a constitutional conflict in November 1988, when the Estonian Supreme Soviet responded to

    Full Text Available This paper aims to describe the writing process of native Russian‑speaking students in Estonian as a second language. 34 participants were given the assignment of writing a text in the L2. The written texts were then rated as being at levels from A2 to C1 according to the Common European Framework of Reference for Languages (CEFR. The data were collected by computer keystroke logging and analysed based on the concept of a ‘micro-context’. Micro-contexts were analysed according to their frequency and duration and were compared across proficiency levels. The results show that writing in the L2 is not a smooth process. The longest transitions in micro-contexts reveal that the most cognitive effort is made between paragraphs and sentences and when deletions are involved. The growing number of consecutive deletions demonstrates that even with developing proficiency, the linear production text is subject to constant revision, correction and modification.

    Pain is a common experience for women during labor. Therefore, pain relief care for mothers during labor is very important. This meta-analysis was conducted to evaluate the efficacy of massage therapy on labor pain reduction in primiparous women. In this meta-analysis, the databases of Web of Knowledge, PubMed, Scopus, Cochrane, Iranmedex, Scientific Information Database (SID), and Magiran were searched for published articles in English and Persian language up to January 2016. Among the studies, with regard to the inclusion and exclusion criteria, 10 studies were selected. Data were analyzed by using Stata software version 11, and standard mean difference (SMD) of effects of massage therapy was calculated. The heterogeneity among studies was evaluated by the Chi-square based Q-test and I 2 statistics. The results of Chi-square based on Q-test and I 2 statistics showed heterogeneity among studies in the latent phase ( Q = 63.52, P value massage therapy reduces labor pain in the latent phase (SMD = -1.23, 95% CI: -1.73 to -0.74), active phase (SMD = -1.59, 95% CI: -2.06 to -1.12), and transitional phase (SMD = -1.90, 95% CI: -3.09 to -0.71). This study provides valid evidence for the effect of massage therapy in Iran for labor pain relief. Therefore, the use of massage therapy can be recommended in the primiparous women.

    Assessment of high-risk Human Papilloma Virus (HPV) prevalence is important for monitoring long-term decrease in cervical cancer after implementation of the prophylactic HPV vaccination. To determine the prevalence of high-risk HPV infection and cytological abnormalities in young primiparous women in the age group of 16-26years. In this cross-sectional study, 214 primiparous women aged 16-26years were recruited from a public tertiary health care center postpartum clinic between June 2013 and May 2014. Cytological analysis was performed by Pap smear test and patients underwent sampling with cervical brushes for HPV-DNA detection and typing by a PCR-based assay for HPV types 16, 18, 33 and 45. High-risk HPV was detected in 41 (19.2%) women. HPV 16 was found to be most prevalent with 17 (7.9%) samples testing positive, followed by HPV 18 in nine (4.2%), HPV 45 in six (2.8%) and HPV 31 in four (1.8%) women. Five women tested positive for more than one HPV types. There were no cases of intraepithelial lesions or cervical cancer. One patient who had Atypical Cells of Undetermined Significance (ASCUS) on cytology tested negative for all four HPV genotypes. This study provides a geographic baseline data of high-risk HPV prevalence in young Indian women before implementation of a vaccination program. The results are important for comparison with other global regions and monitoring the effect of HPV vaccination.

    Promoting handwashing with soap to mothers of young children can significantly reduce diarrhoea and pneumonia morbidity among children, but studies that measured long-term behaviour after interventions rarely found improvements in handwashing habits. Expecting mothers may experience emotional and social changes that create a unique environment that may encourage adoption of improved handwashing habits. The objective of this study was to determine whether exposure to an intensive handwashing intervention in the perinatal period (perinatal arm) was associated with improved maternal handwashing behaviour vs. exposure to the same intervention after the end of the perinatal period (post-neonatal arm). We identified primiparous women previously enrolled a randomised controlled handwashing intervention trial (November 2010-December 2011) and observed handwashing behaviours at the home 1-14 months after completion of the RCT (January-May 2012). We observed maternal handwashing and estimated the prevalence ratio (PR) of maternal handwashing using log-binomial regression. We enrolled 107 mothers in the perinatal arm and 105 mothers in the post-neonatal arm. Handwashing with soap at recommended times was low overall (4.6%) and comparable between arms (PR = 0.9, 95% CI 0.5, 1.5). This handwashing intervention was unable to develop and establish improved handwashing practices in primiparous women in rural Bangladesh. While pregnancy may present an opportunity and motivation to do so, further studies should assess whether social, individual and environmental influences overcome this motivation and prevent handwashing with soap among new mothers. © 2016 John Wiley & Sons Ltd.

    Occupational use of computers has increased rapidly over recent decades, and has been linked with various musculoskeletal disorders, which are now the most commonly diagnosed occupational diseases in Estonia. The aim of this study was to assess the prevalence of musculoskeletal pain (MSP) by anatomical region during the past 12 months and to investigate its association with personal characteristics and work-related risk factors among Estonian office workers using computers. In a cross-sectional survey, the questionnaires were sent to the 415 computer users. Data were collected by self-administered questionnaire from 202 computer users at two universities in Estonia. The questionnaire asked about MSP at different anatomical sites, and potential individual and work related risk factors. Associations with risk factors were assessed by logistic regression. Most respondents (77%) reported MSP in at least one anatomical region during the past 12 months. Most prevalent was pain in the neck (51%), followed by low back pain (42%), wrist/hand pain (35%) and shoulder pain (30%). Older age, right-handedness, not currently smoking, emotional exhaustion, belief that musculoskeletal problems are commonly caused by work, and low job security were the statistically significant risk factors for MSP in different anatomical sites. A high prevalence of MSP in the neck, low back, wrist/arm and shoulder was observed among Estonian computer users. Psychosocial risk factors were broadly consistent with those reported from elsewhere. While computer users should be aware of ergonomic techniques that can make their work easier and more comfortable, presenting computer use as a serious health hazard may modify health beliefs in a way that is unhelpful.

    The data set for this study comprised 1,488,474 test-day records for milk, fat, and protein yields and fat and protein percentages from 191,012 first-, second-, and third-parity Holstein cows from 484 farms. Data were collected from 2001 through 2007 and merged with meteorological data from 35 weather stations. A linear model (M1) was used to estimate the effects of the temperature-humidity index (THI) on production traits. Least squares means from M1 were used to detect the THI thresholds for milk production in all parities by using a 2-phase linear regression procedure (M2). A multiple-trait repeatability test-model (M3) was used to estimate variance components for all traits and a dummy regression variable (t) was defined to estimate the production decline caused by heat stress. Additionally, the estimated variance components and M3 were used to estimate traditional and heat-tolerance breeding values (estimated breeding values, EBV) for milk yield and protein percentages at parity 1. An analysis of data (M2) indicated that the daily THI at which milk production started to decline for the 3 parities and traits ranged from 65 to 76. These THI values can be achieved with different temperature/humidity combinations with a range of temperatures from 21 to 36°C and relative humidity values from 5 to 95%. The highest negative effect of THI was observed 4 d before test day over the 3 parities for all traits. The negative effect of THI on production traits indicates that first-parity cows are less sensitive to heat stress than multiparous cows. Over the parities, the general additive genetic variance decreased for protein content and increased for milk yield and fat and protein yield. Additive genetic variance for heat tolerance showed an increase from the first to third parity for milk, protein, and fat yield, and for protein percentage. Genetic correlations between general and heat stress effects were all unfavorable (from -0.24 to -0.56). Three EBV per trait were

    There are many parenting problems during infancy for Chinese primiparous women. As an important determinant of good parenting, maternal self-efficacy (MSE) should be paid more attention by researchers. At present, the limitations of previous research examining MSE during infancy are that most studies were conducted with a homogeneous sample and there were few studies with Chinese women. Secondly, the trajectory of change in MSE, postnatal depression symptoms and social support for Chinese primiparous women was not clear during the initial postpartum period in earlier studies. This study aimed to describe changes in MSE, postnatal depression symptoms and social support among Chinese primiparous women in the first three months postnatally. A quantitative longitudinal study using questionnaires was conducted. Obstetric wards at three hospitals in Xiamen City, South-East China. In total, 420 Chinese primiparous women were recruited. Initial baseline questionnaires to measure socio-demographic and clinical characteristics at three days postnatally were distributed to participants face-to-face by the researcher on the postnatal ward. Follow-up questionnaires at six and 12 weeks postnatally were sent via e-mail by the researcher to participants, including the Self-efficacy in Infant Care Scale (SICS), the Edinburgh Postnatal Depression Scale (EPDS) and the Postpartum Social Support Scale (PSSS) to measure MSE, postnatal depression symptoms and social support, respectively. These were returned by participants via e-mail. Quantitative data were analysed using SPSS. The mean MSE score at six weeks postnatally was 74.92 (SD = 11.05), and increased to 77.78 (SD = 11.13) at 12 weeks postnatally. The mean social support scores at six and 12 weeks postnatally were 40.99 (SD = 9.31) and 43.00 (SD = 9.55). The mean EPDS scores decreased from 9.09 (SD = 4.33) at six weeks postnatally to 8.63 (SD = 4.40) at 12 weeks postnatally; the proportion of women with an

    Over two decades of observations in the field in South East Asia and Hawai'i suggest that majority of the commercial dairy herds are of black hair coat. Hence a simple study to determine the accuracy of the observation was conducted with two large dairy herds in Hawaii in the mid-1990s. A retrospective study on longevity of Holstein cattle in the tropics was conducted using DairyComp-305 lactation information coupled with phenotypic evaluation of hair coat color in two large dairy farms. Cows were classified into 3 groups: a) black (B, >90%); b) black/white (BW, 50:50) and c) white (W, >90%). Cows with other hair coat distribution were excluded from the study. In farm A, 211 out of 970 cows were identified having 4 or more lactations. In farm B, 690 out of 1,350 cows were identified with 2 or more lactations for the study. The regression analyses and the Wilcoxon-Log-rank test for survival probability showed that Holstein cattle with 90% black hair coat had greater longevity compared to Holstein cattle with 90% white hair coat. This study suggests that longevity of Holstein cattle in tropical regions was influenced by hair coat color and characteristics.

    Several milk metabolites are associated with breeds or species of dairy animals. A better understanding of milk metabolites from different dairy animals would advance their use in evaluating milk traits and detecting milk adulteration. The objective of this study was to characterize the milk metabolite profiles of Chinese Holstein, Jersey, yak, buffalo, goat, camel, and horse and identify any differences using non-targeted metabolomic approaches. Milk samples were tested using nuclear magnetic resonance (NMR) spectroscopy and liquid chromatography-tandem mass spectrometry (LC-MS). Data were analyzed using a multivariate analysis of variance and differences in milk metabolites between Holstein and the other dairy animals were assessed using orthogonal partial least-squares discriminant analysis. Differential metabolites were identified and some metabolites, such as choline and succinic acid, were used to distinguish Holstein milk from that of the other studied animals. Metabolic pathway analysis of different metabolites revealed that glycerophospholipid metabolism as well as valine, leucine, and isoleucine biosynthesis were shared in the other ruminant animals (Jersey, buffalo, yak, and goat), and biosynthesis of unsaturated fatty acids was shared in the non-ruminant animals (camel and horse). These results can be useful for gaining a better understanding of the differences in milk synthesis between Holstein and the other dairy animals. Copyright © 2016. Published by Elsevier B.V.

    Full Text Available The article demonstrates different meanings of the motif of Hamlet in the Estonian culture. Hamlet as a literary figure has been very important and influential, a symbol of will and a fighter in a hopeless situation. Paul-Eerik Rummo’s poem “Hamlet’s Songs” (1964 forms the centre around which revolve not only written texts but also many such cultural texts as theatre performances and music, all connected by allusions to Hamlet. Rummo’s poem is one of the most innovative poems from the 1960s in Estonian literature. The generation of the 1960s was influenced by several important contemporary theories, including existentialism. Many young writers systematically undermined the Soviet regime in their works. The use of the motif of Hamlet reveals a similarity between the existential and romantic rebellions. Rummo’s dialogue with Hamlet in his poem expresses optimism in a hopeless situation in a way different from Shakespeare’s.

  13. Describing temporal variability of the mean Estonian precipitation series in climate time scale

    2009-04-01

    Applicability of the random walk type models to represent the temporal variability of various atmospheric temperature series has been successfully demonstrated recently (e.g. Kärner, 2002). Main problem in the temperature modeling is connected to the scale break in the generally self similar air temperature anomaly series (Kärner, 2005). The break separates short-range strong non-stationarity from nearly stationary longer range variability region. This is an indication of the fact that several geophysical time series show a short-range non-stationary behaviour and a stationary behaviour in longer range (Davis et al., 1996). In order to model series like that the choice of time step appears to be crucial. To characterize the long-range variability we can neglect the short-range non-stationary fluctuations, provided that we are able to model properly the long-range tendencies. The structure function (Monin and Yaglom, 1975) was used to determine an approximate segregation line between the short and the long scale in terms of modeling. The longer scale can be called climate one, because such models are applicable in scales over some decades. In order to get rid of the short-range fluctuations in daily series the variability can be examined using sufficiently long time step. In the present paper, we show that the same philosophy is useful to find a model to represent a climate-scale temporal variability of the Estonian daily mean precipitation amount series over 45 years (1961-2005). Temporal variability of the obtained daily time series is examined by means of an autoregressive and integrated moving average (ARIMA) family model of the type (0,1,1). This model is applicable for daily precipitation simulating if to select an appropriate time step that enables us to neglet the short-range non-stationary fluctuations. A considerably longer time step than one day (30 days) is used in the current paper to model the precipitation time series variability. Each ARIMA (0

    Serotonin is known to regulate energy and calcium homeostasis in several mammalian species. The objective of this study was to determine if pre-partum infusions of 5-hydroxytryptophan (5-HTP), the immediate precursor to serotonin synthesis, could modulate energy homeostasis at the level of the hepatocyte in post-partum Holstein and Jersey dairy cows. Twelve multiparous Holstein cows and twelve multiparous Jersey cows were intravenously infused daily for approximately 7 d pre-partum with either saline or 1 mg/kg bodyweight of 5-HTP. Blood was collected for 14 d post-partum and on d30 post-partum. Liver biopsies were taken on d1 and d7 post-partum. There were no changes in the circulating concentrations of glucose, insulin, glucagon, non-esterified fatty acids, or urea nitrogen in response to treatment, although there were decreased beta-hydroxybutyrate concentrations with 5-HTP treatment around d6 to d10 post-partum, particularly in Jersey cows. Cows infused with 5-HTP had increased hepatic serotonin content and increased mRNA expression of the serotonin 2B receptor on d1 and d7 post-partum. Minimal changes were seen in the hepatic mRNA expression of various gluconeogenic enzymes. There were no changes in the mRNA expression profile of cell-cycle progression marker cyclin-dependent kinase 4 or apoptotic marker caspase 3, although proliferating cell nuclear antigen expression tended to be increased in Holstein cows infused with 5-HTP on d1 post-partum. Immunofluorescence assays showed an increased number of CASP3- and Ki67-positive cells in Holstein cows infused with 5-HTP on d1 post-partum. Given the elevated hepatic serotonin content and increased mRNA abundance of 5HTR2B, 5-HTP infusions may be stimulating an autocrine-paracrine adaptation to lactation in the Holstein cow liver.

    Full Text Available Seminatural grasslands i.e. the floodplain meadows, seashore meadows, wooded meadows, dry meadows, wooded pastures are the very traditional part of Estonian landscapes, which play an important role in the appearance of the landscape in general and also serve as an important habitat for many plant and animal species. In order to preserve the seminatural grasslands continuous annual mowing and/or pasturing is needed. This activity is not economically profitable and needs subsidizing. The authors of the work raise a hypothesis that the Estonian seminatural grasslands could be viewed as a valuable non-market environmental good for which a significant public demand exists. In order to find out the non-market value of the seminatural grasslands a contingent valuation study was carried out among the Estonian working-age population (size of the sample 1061 individuals. The average individual willingness to pay was 11.3 euros. During the study, the authors constructed the total demand function and discovered that the total annual demand for seminatural grasslands was 17.9 million euros.

    Full Text Available The article describes the conception and editing process of an anthology of Johannes Becher’s poems (Unistades täiusest, 1962 in Estonian, and discusses its status in the Soviet and contemporary literary canon. The work on the Becher anthology was led by an already outstanding literary scholar Nigol Andresen and a young poet and translator Ain Kaalep, who later became one of the most prolific and wellknown poetry translators in Estonia. An important part was also played by another poet-translator, August Sang, who already had achieved such a standing in the Estonian literary field. Several other translators contributed to the anthology, making it a common project for intellectuals otherwise very differently positioned vis-à-vis the Soviet political authorities and cultural agendas. Becher’s work was strongly promoted by these instances, but his poetry was also read with genuine enthusiasm by the main contributors to the anthology (whose own poetry has certain parallels to some aspects of Becher’s, as well as the general public, at that time. After the fall of the Soviet regime it has been forgotten, mostly for the same contextual reasons that once granted its success. The case of his poetry in Estonian explores the question of this new invisibility of now politically irrelevant, but still voluminous and aesthetically intriguing literary works in the post-Soviet canon.

    . Characteristics of cortisol concentration patterns were not related to characteristics of LH concentration patterns for ES cows (P > 0.10. However, as cortisol pulse amplitude increased, LH pulse amplitude decreased (b1 = -0.04; P Conclusions In conclusion, exposing primiparous, postpartum, anovular, suckled cows to bulls for 5-h daily over a 9-d period did not alter mean concentrations of cortisol or LH compared to mean concentrations of cortisol and LH in cows exposed to steers. However, exposing cows to bull in this manner altered characteristics of temporal patterns of both LH and cortisol by increasing LH pulse frequency and decreasing cortisol pulse frequency. Interestingly, in cows exposed to bulls, as amplitude and frequency of cortisol pulses decreased, amplitudes of LH pulses increased and frequency of LH pulses tended to increase. Thus, the physiological mechanism of the biostimulatory effect of bulls may initially involve modification of the HPA axis and these changes may facilitate activation of the HPO axis and resumption of ovulatory cycles in postpartum, anovular, suckled cows.

    Full Text Available For dairy cattle breeds, mainly the taurine ones, the selection emphasized for many years the increase in milk yields and, as a consequence, the adaptive and reproductive traits were negatively affected. The aim of this study was to verify the influence of genetic and environmental effects on the reproductive traits in a dairy herd selected for high milk production levels. The data set comprised 1,737 first lactations Holsteins cows of Agrindus Farm, located at Southeastern region of Brazil. The records of the following reproductive traits: calving to first heat interval (CFHI, calving to conception interval (CCI and first to second calving interval (FCI were analyzed as dependent variables by least squares method using GLM procedure (SAS. Linear models were considered including two production levels (1= less than 9,500 kg and 2= more than 9,501 kg of total milk yield, contemporary group (year and months calving, management group, sire of cow, and the sire used to breeding cows, as classificatory variables. As covariates were included for all traits the peak milk yield in lactation (linear effect, age at calving only for CFHI (linear and quadratic effects since this effect was not significant for other traits, and CFHI (linear effect only for FCI. The coefficients of determination represented 24%, 74% and 75%, respectively for CFHI, FCI and CCI models. Production level, peak milk yield and sire effects were significant (P<0.05 for all traits. The average estimated for high and low milk production level were 73 and 79 days, 500 and 601 days, 227 and 330 days for CFHI, FCI and CCI, respectively, suggesting that cows with higher genetic potential for milk had worse reproductive performance. Similarly, lactation peak showed significant effect (P<0.05 for all traits, suggesting higher peaks cows showed also poorer reproductive rates. Sire effect also was a variable that showed significant effect (P<0.01 for all traits, which means that there was

    Purpose: Detection of morphological and functional changes of the pelvic floor with functional MRI in primiparous women after spontaneous vaginal delivery. Methods and Materials: The study comprises 26 primiparous women after vaginal delivery and a control group of 41 healthy asymptomatic nulliparous volunteers. MRI was performed on a 1.5 T system in supine position with vagina and rectum opacified with Sonogel. The static images consisted of sagittal and axial T{sub 2}-weighted SE sequences and functional images of true FISP sequences in midsagittal and axial planes acquired with the patient at rest, straining and during defecation. Evaluation of morphometric parameters included pelvimetry, thickness of the puborectal muscle and width of the urogenital hiatus as well as position and movement of the pelvic organs relative to the pubococcygeal reference line. Results: The configuration of the bony pelvis did not differ for both groups. The puborectal muscle was significantly thinner in the study group (0.8 cm vs 0.6 cm). The functional images showed no significant differences between both groups at rest but a significantly increased incidence in the descent of the bladder neck, vaginal fornix and anorectal junction in the study group during straining. In addition, the primiparous women had more prominent rectoceles (0.6 cm vs 1.5 cm). Conclusion: Static imaging alone fails to demonstrate relevant pelvic floor changes and a functional method is necessary to evaluate the interactions of the pelvic organs regarding organ descent. Functional MRI of the pelvic floor is an excellent method to reveal the significant changes of the pelvic floor after vaginal birth without exposing the uterus to radiation. (orig.)

    Full Text Available According to theatre scholar Freddie Rokem, theatre portraying or performing historical events is seeking to overcome both the separation and the exclusion from the past, as well as ’striving to create a community where the events from this past will matter again’. This article covers the topic of interpretations of national history in Estonian theatre and in original dramaturgy during the Soviet era, with the focus on aspects like national self-reflection and the relationship to the common past. The main focus is on the 1970s, with examples from Rein Saluri’s, Mati Unt’s and Jaan Kaplinski’s drama productions. During the period in question, re-tellings of national history on Estonian theatre stages were clothed in metaphors, allusions and secret codes – Aesopian language. Within the Soviet cultural context, I analyse if and to what extent theatre of the time displayed resistance, political theatre or social allegory. Theatre was also connected with the principle of playing or playfulness, which on one hand indicates national resistance, national endurance, and a certain survival strategy, but on the other hand indicates the Estonian as being an involuntary homo ludens – the Playing Man, who through various enforced roles is trying to adjust to the whirlwinds of history. Saluri’s first play, the intellectual drama Külalised (The Guests, opens with an allusion to a drama classic the world over, William Shakespeare’s Hamlet, adding a powerful national-symbolic background to the play. The role-play which permeates and structures the play (The Host–The Guest however, displays allegorical references to changes in the status and self-image of Estonians. In Unt’s play Peaproov (Dress Rehearsal, the principle of playing/acting sheds ironic light on the makers of an historical film and their readiness to create superficially flashy interpretations at any cost: this take acts as an estranging and generalising reflection in a context

    Full Text Available Bernhard Linde (1886–1954 was a recognized and prolific Estonian theatre critic of the first quarter of the 20th century, who mediated and propagated western as well as eastern European theatrical innovations. In addition, he was active as a literary and art critic, publisher, and proponent of libraries, to a modest extent he was a prose writer and poet. Unquestionably, however, Bernhard Linde’s most prominent role was as one of the founding members of the literary movement Young Estonia. He was the group’s first general manager; later on, he was the secretary of the Estonian Writers’ Association Young Estonia, and the chairman of the board of the Young Estonia Publishing House. Linde’s formal education culminated in graduation from Tartu University as a Slavic philologist; he was the only member of the Young Estonia group to demonstrate serious and sustained interest toward Slavic cultures and peoples. Linde was a contradictory figure, evoking a range of responses from his contemporaries: on the one hand, there was the unbelievably broad range of his participation in cultural life, his organizing skills and business instincts in directing publishing houses; on the other hand, a superficiality in his writings, his often rash and subjective style as a critic, and his financial intrigues. If one adds in Linde’s stubbornness, egocentrism, and intense spirit of protest, which often led to lawsuits, the outcome is the portrait of an extremely complicated, fascinating, and passionate man—both in his creative work and his personal life Linde guaranteed a place for himself in literary history through a small catch of texts: a few foundational essays (for example, on August Kitzberg, a translation of Balzac’s Le père Goriot, the essay collection Omad ja võõrad (Own and Foreign and a travel book focusing on the literature and theatre of eastern Europe (Loova Kesk-Euroopa Poole (Toward A Creative Central Europe.

    Full Text Available Background & aim: Mother-infant bonding and interactions after childbirth are shaped by maternal-fetal attachment during pregnancy. Although many studies have shown the positive correlation between maternal-fetal attachment and mother-infant attachment behaviors, some controversial studies have shown otherwise. Therefore, this study aimed to evaluate the correlation between maternal-fetal attachment and mother-infant attachment behaviors in primiparous women. Methods:This descriptive correlational study was conducted on 100 primiparous women, referring to the selected heath care centers of Mashhad. Data were collected using Cranley's maternal–fetal attachment scale, Avant’s mother-infant attachment tool, Edinburgh postnatal depression scale, and a demographic/obstetric questionnaire including demographic data, obstetric information, delivery outcomes, and postpartum data. Pregnant women with a gestational age of 35-41 weeks, who met the inclusion criteria, completed Cranley's questionnaire, as well as the demographic/obstetric questionnaire. Four and eight weeks after delivery, the subjects were asked to complete the Edinburgh questionnaire and postpartum information; then, they were asked to breastfeed their infants on a chair in a quiet place for 15 minutes. The researcher observed the mothers’ behaviors toward their neonates. For data analysis, descriptive and analytical tests were performed, using SPSS version 16. Results: There was a direct positive relationship between maternal-fetal attachment and mothers’ emotional behaviors toward infants four and eight weeks after delivery. However, four and eight weeks after childbirth, no significant correlation was found between maternal-fetal attachment and mothers’ caring behaviors. Conclusion: According to the findings, maternal-fetal attachment is one of the most important factors for mother-infant attachment. These findings could be applied for enriching mother-infant attachment

The number of corpora lutea per female was 1.3 ± 0.5 and 2.0 ± 0.0 respectively for MOD1 and MOD4. No pre-embryonic mortality was recorded. The mean weight of the young guinea pigs of MOD1 (54.7 ± 10. g was only 55% of that of MOD4 (98.6 ± 13.6 g. At weaning, the average weight gain of young guinea pigs of MOD1 (40.5 ± 22.2 g represented a third of those obtained with other diets that did not significantly differ. At the end of RC, the weight gain of dams was 17 ± 13.3% for MOD1 compared to 50% for MOD2, MOD3 and MOD4. Feeding Panicum maximum alone induces chronic malnutrition which in turn is responsible of the low ovulation rate and reduced growth in guinea pig breeding.

    To evaluate changes to the pelvic floor of primiparous women with different delivery modes, using three-dimensional ultrasound. A prospective cross-sectional study on 35 primiparae divided into groups according to the delivery mode: elective cesarean delivery (n=10), vaginal delivery (n=16), and forceps delivery (n=9). Three-dimensional ultrasound on the pelvic floor was performed on the second postpartum day with the patient in a resting position. A convex volumetric transducer (RAB4-8L) was used, in contact with the large labia, with the patient in the gynecological position. Biometric measurements of the urogenital hiatus were taken in the axial plane on images in the rendering mode, in order to assess the area, anteroposterior and transverse diameters, average thickness, and avulsion of the levator ani muscle. Differences between groups were evaluated by determining the mean differences and their respective 95% confidence intervals. The proportions of levator ani muscle avulsion were compared between elective cesarean section and vaginal birth using Fisher's exact test. The mean areas of the urogenital hiatus in the cases of vaginal and forceps deliveries were 17.0 and 20.1 cm(2), respectively, versus 12.4 cm(2) in the Control Group (elective cesarean). Avulsion of the levator ani muscle was observed in women who underwent vaginal delivery (3/25), however there was no statistically significant difference between cesarean section and vaginal delivery groups (p=0.5). Transperineal three-dimensional ultrasound was useful for assessing the pelvic floor of primiparous women, by allowing pelvic morphological changes to be differentiated according to the delivery mode.

    Full Text Available Abstract Background Preventive drugs require long-term trials to show their effectiveness or harms and often a lot of changes occur during post-marketing studies. The purpose of this article is to describe the research process in a long-term randomized controlled trial and discuss the impact and consequences of changes in the research environment. Methods The Estonian Postmenopausal Hormone Therapy trial (EPHT, originally planned to continue for five years, was planned in co-operation with the Women's International Study of Long-Duration Oestrogen after Menopause (WISDOM in the UK. In addition to health outcomes, EPHT was specifically designed to study the impact of postmenopausal hormone therapy (HT on health services utilization. Results After EPHT recruited in 1999–2001 the Women's Health Initiative (WHI in the USA decided to stop the estrogen-progestin trial after a mean of 5.2 years in July 2002 because of increased risk of breast cancer and later in 2004 the estrogen-only trial because HT increased the risk of stroke, decreased the risk of hip fracture, and did not affect coronary heart disease incidence. WISDOM was halted in autumn 2002. These decisions had a major influence on EPHT. Conclusion Changes in Estonian society challenged EPHT to find a balance between the needs of achieving responses to the trial aims with a limited budget and simultaneously maintaining the safety of trial participants. Flexibility was the main key for success. Rapid changes are not limited only to transiting societies but are true also in developed countries and the risk must be included in planning all long-term trials. The role of ethical and data monitoring committees in situations with emerging new data from other studies needs specification. Longer funding for preventive trials and more flexibility in budgeting are mandatory. Who should prove the effectiveness of an (old drug for a new preventive indication? In preventive drug trials companies may

    1988-01-01

    Two kinds of bosonic expansions for the SU(2) case, one being finite (Schwinger) and the other being infinite (Holstein-Primakoff) are analysed. The existence of a transformation connecting them was discussed. Utilizing the two methods, the Two Level Model hamiltonian into the many boson space is mapped. Considering systems composed by 4, 6 and 14 particles, calculations for the eigenenergies within the ''vibrational limit'' of the model were performed. The results show that the Schwinger mapping is exact. Approximated bosonic images with the Holstein-Primakoff mapping are obtained. Indeed, the anharmonicities observed in the region between the ideal '' spherical limit'' and the ''transitional point'', were well described by the approximation containing up to quartic terms on the bosonic operators.

    Full Text Available The objective of this work was to evaluate the performance of Holstein calves in suckling and post-weaning phases, intensively managed during suckling in the absence or presence of hay. Twenty-four male Holstein calves, at an average age of 15 days and initial weight of 43 kg were used in the experiment. The experimental design was completely randomized, consisting of two treatments and six replications. The treatments were as follows: 1 suckling with milk substitute + initial concentrate for calves, ad libitum + temperate grass hay (oat/ryegrass, ad libitum; 2 suckling with milk substitute + initial concentrate for calves, ad libitum. No significant difference was found between treatments for weight gain and feed conversion. However, the supply of hay caused an increase in daily dry matter intake (2.127 vs 1.894 kg. The intake of hay promoted greater stimulus to consumption of concentrate and greater weight at weaning.

    Full Text Available The aim of this work was to analyse the influence of certain characteristics (aptitude, age, carcass weight, net daily gain, feeding on the final carcass classification in the SEUROP system. 703 Czech Fleckvieh bulls and 642 Holstein bulls were studied. The animals were slaughtered and evaluated at a designated beef processing company. Combine aptitude carcasses shown significant differences between characteristics. Remarkable differences of group averages (P>0, 01 were established between farms and they were due to various rearing conditions. Also the levels of net daily gain between aptitudes were proved significantly. Holstein breed showed significant difference among The net daily gain < 500 g.day–1 and levels 551–600; 601–650 and above 651 g.day–1. The SEUROP system is influenced the most by the feeding regime, which is described by a net daily gain in this work, and farm impact.

  13. Eesti patsient. Haiguse ja haige inimese kujutamise mudel 19. sajandi eesti kultuuris ja kirjasõnas. The Estonian Patient: A Model for the Representation of Illness and the Ill in 19th Century Estonian Culture and Letters

    2012-04-01

    Full Text Available The portrait of the 18th and 19th century „Estonian patient” sketched in this article is a theoretical model of the ill person, based mainly on literary texts, but with reference to a variety of scientific and popular-scientific material. The point of departure is the classic postcolonial theorist, Frantz Fanon, in whose writings medicine, healing, and discourse on such topics are seen as the functioning of a specific colonial practice. The most notable characteristic of the figure of the Estonian patient is non-communicativeness. Communication is avoided and feared primarily because it has to be directed toward those in higher positions of power, or to institutions that embody power (the apothecary, the hospital. While these traits also characterize the separation between peasants and their rulers more generally, in a situation of illness the exclusion is felt with a double intensity. Sickness casts the peasant in a double bind: when in need of help or healing, contact across the divide between social rank, and – more broadly, between two cultures and ways of understanding the world, becomes unavoidable. In such situations, illness signifies an intensification of the gap in social standing. The ill person, who already stands on a lower rung of the social hierarchy, becomes all the more marginalized. In keeping with these observations, the real reason behind indecisiveness and refusal of medical treatment may well be an effort to avoid or postpone humiliation on the basis of lower social standing. Other contributing factors might include unconscious resistance – or even a conscious model of resistance – in the psyche, which manifests as an avoidance of communication. The content and motivating force for the model is not heroism, but rather a sense of shame. Indeed, behind the context of medical culture lurks ethnic and material isolation. The individual’s economic situation, living conditions, education and – most important – his

    Highlights: • There exists an optimal Boson energy for superconductivity in Hubbard–Holstein model. • The electron-Boson coupling is essential for superconductivity, but the same coupling can lead to polaron insulator, which is against superconductivity. • The local Coulomb repulsion can sometimes enhance superconductivity. - Abstract: We examine the superconducting solution in the Hubbard–Holstein model using Dynamical Mean Field Theory. The Holstein term introduces the site-independent Boson fields coupling to local electron density, and has two competing influences on superconductivity: The Boson field mediates the effective electron-electron attraction, which is essential for the S-wave electron pairing; the same coupling to the Boson fields also induces the polaron effect, which makes the system less metallic and thus suppresses superconductivity. The Hubbard term introduces an energy penalty U when two electrons occupy the same site, which is expected to suppress superconductivity. By solving the Hubbard–Holstein model using Dynamical Mean Field theory, we find that the Hubbard U can be beneficial to superconductivity under some circumstances. In particular, we demonstrate that when the Boson energy Ω is small, a weak local repulsion actually stabilizes the S-wave superconducting state. This behavior can be understood as an interplay between superconductivity, the polaron effect, and the on-site repulsion: As the polaron effect is strong and suppresses superconductivity in the small Ω regime, the weak on-site repulsion reduces the polaron effect and effectively enhances superconductivity. Our calculation elucidates the role of local repulsion in the conventional S-wave superconductors.

    This study was undertaken to first quantify the effect of heat stress on milk yield and components of Tarentaise in comparison to Holstein cows. A dataset of 16,143 monthly individual records of production traits was collected for 435 Tarentaise and 543 Holstein cows from 21 farms in Tunisia (2009 to 2014). This dataset was merged with meteorological data from 5 public stations relative to the 21 farms. The temperature-humidity index (THI), calculated as a combination of ambient temperature and relative humidity, was used to characterize heat stress. When the THI increased from an average value of 53.7 in winter to 75.4 in summer, the Holstein and Tarentaise cows decreased their milk production by 0.93 and 0.15 kg/day, respectively. Milk fat, protein, and urea content decreased similarly in both breeds (-2.20 g/kg, -1.40 g/kg, and -14 mg/L, respectively), and the milk somatic cell count increased for Holstein cows (+352,000/mL) while decreased for Tarentaise cows (-160,000/mL). The second aim of this study was to describe the relationship between the variations of the milk yields between the summer and the winter (Δ milk yields) and some barn characteristics during the hot season. A survey carried out on 19 of the 21 previous farms permitted to conclude that the closed buildings led to a higher decrease in milk yield between the summer and winter than the open buildings (-1.13 vs. -0.27 kg/day). A metallic roof had a more negative impact on Δ milk yields than the other roof types (-1.04 vs. -0.15 kg/day).

    Calves with congenital defects born to cows that have grazed teratogenic Lupinus spp. during pregnancy can suffer from what is termed crooked calf syndrome. Crooked calf syndrome defects include cleft palate, spinal column defects and limb malformations formed by alkaloid-induced inhibition of fetal movement. In this study, we tested the hypothesis that there are differences in fetal activity of fetuses carried by Holstein verses Angus heifers orally dosed with 1.1 g/kg dried ground Lupinus leucophyllus. Fetal activity was monitored via transrectal ultrasonography and maternal serum was analyzed for specific lupine alkaloids. There were more (P Angus heifers at eight and 12 h after oral dosing. In addition to serum alkaloid toxicokinetic differences, the Holstein heifers had significantly lower serum concentrations of anagyrine at 2, 4, and 8 h after oral dosing than Angus heifers. Holstein heifers also had significantly greater serum concentrations of lupanine at 12, 18 and 24 h after dosing than the Angus heifers. These results suggest that there are breed differences in susceptibility to lupine-induced crooked calf syndrome. These differences may also be used to discover genetic markers that identify resistant animals, thus facilitating selective breeding of resistant herds. Published by Elsevier Ltd.

    Two-dimensional (2D) crystals have emerged as a class of materials with tunable carrier density 1 . Carrier doping to 2D semiconductors can be used to modulate many-body interactions 2 and to explore novel composite particles. The Holstein polaron is a small composite particle of an electron that carries a cloud of self-induced lattice deformation (or phonons) 3-5 , which has been proposed to play a key role in high-temperature superconductivity 6 and carrier mobility in devices 7 . Here we report the discovery of Holstein polarons in a surface-doped layered semiconductor, MoS 2 , in which a puzzling 2D superconducting dome with the critical temperature of 12 K was found recently 8-11 . Using a high-resolution band mapping of charge carriers, we found strong band renormalizations collectively identified as a hitherto unobserved spectral function of Holstein polarons 12-18 . The short-range nature of electron-phonon (e-ph) coupling in MoS 2 can be explained by its valley degeneracy, which enables strong intervalley coupling mediated by acoustic phonons. The coupling strength is found to increase gradually along the superconducting dome up to the intermediate regime, which suggests a bipolaronic pairing in the 2D superconductivity.

    A main goal of cattle genomics is to identify DNA differences that account for variations in economically important traits. In this study, we performed whole-genome analyses of three important cattle breeds in Korea—Hanwoo, Jeju Heugu, and Korean Holstein—using the Illumina HiSeq 2000 sequencing platform. We achieved 25.5-, 29.6-, and 29.5-fold coverage of the Hanwoo, Jeju Heugu, and Korean Holstein genomes, respectively, and identified a total of 10.4 million single nucleotide polymorphisms (SNPs), of which 54.12% were found to be novel. We also detected 1,063,267 insertions–deletions (InDels) across the genomes (78.92% novel). Annotations of the datasets identified a total of 31,503 nonsynonymous SNPs and 859 frameshift InDels that could affect phenotypic variations in traits of interest. Furthermore, genome-wide copy number variation regions (CNVRs) were detected by comparing the Hanwoo, Jeju Heugu, and previously published Chikso genomes against that of Korean Holstein. A total of 992, 284, and 1881 CNVRs, respectively, were detected throughout the genome. Moreover, 53, 65, 45, and 82 putative regions of homozygosity (ROH) were identified in Hanwoo, Jeju Heugu, Chikso, and Korean Holstein respectively. The results of this study provide a valuable foundation for further investigations to dissect the molecular mechanisms underlying variation in economically important traits in cattle and to develop genetic markers for use in cattle breeding.

    We study the interplay between the electron-phonon (e -ph) and on-site electron-electron (e-e) interactions in a three-orbital Hubbard-Holstein model on an extended one-dimensional lattice using determinant quantum Monte Carlo. For weak e-e and e -ph interactions, we observe a competition between an orbital-selective Mott phase (OSMP) and a (multicomponent) charge-density-wave (CDW) insulating phase, with an intermediate metallic phase located between them. For large e-e and e -ph couplings, the OSMP and CDW phases persist, while the metallic phase develops short-range orbital correlations and becomes insulating when both the e-e and e -ph interactions are large but comparable. Many of our conclusions are in line with those drawn from a prior dynamical mean-field theory study of the two-orbital Hubbard-Holstein model [Phys. Rev. B 95, 121112(R) (2017), 10.1103/PhysRevB.95.121112] in infinite dimension, suggesting that the competition between the e -ph and e-e interactions in multiorbital Hubbard-Holstein models leads to rich physics, regardless of the dimension of the system.

    Hydrometer measurement in globulin and IgG1 concentration measured by the radial immunodiffusion technique were compared for 915 samples of first milking colostrum from Holstein cows. Least squares analysis of the relationship between hydrometer measurement and IgG1 concentration was improved by log transformation of IgG1 concentration and resulted in a significant linear relationship between hydrometer measurement and log10 IgG1 concentration; r2 = .469. At 50 mg of globulin/ml of colostrum, the recommended hydrometer cutoff point for colostrum selection, the sensitivity of the hydrometer as a test of IgG1 concentration in Holstein colostrum was 26%, and the negative predictive value was 67%. The negative predictive value and sensitivity of the hydrometer as a test of IgG1 in Holstein colostrum was improved, and the cost of misclassification of colostrum was minimized, when the cutoff point for colostrum selection was increased above the recommended 50 mg/ml.

    Full Text Available The objective of this study was to compare growth performances of male and female Holstein calves fed milk and milk replacers. A total of 60 Holstein calves were used in the study. Calves were divided into three equal groups. In each group, there were 10 female and 10 male calves. Calves were offered colostrum for 3 days after birth and were weighed at fourth day for the trial. Initial body weights of calves in dietary treatments were statistically similar. The first, second and third groups were fed milk, milk replacer-I (CP 21% and CF 16.5% and milk replacer-II (CP 24% and CF 18%, respectively. In addition to milk and milk replacers, calves were supplemented with ad libitum concentrate feed and alfalfa. Dietary treatment was significantly effective (P<0.05 on body weight of calves at 60 days of age. In conclusion, growth performances of calves increased with increasing protein content of milk replacer had better than those of calves fed milk replacer containing low-protein. Therefore, during the suckling period, in feeding of Holstein calves, milk or milk replacer containing high-protein should be preferred primarily.

    A general and dramatic deterioration of health in Estonia during the transition period 1990-1994 was analysed using Sweden as a comparative example. Though there were diverging trends between Estonia and Sweden in the leading cause of death, cardiovascular diseases, the gap in mortality from injury had increased most rapidly. While the injury mortality rate slightly decreased in Sweden from 1990 to 1994, it almost doubled in Estonia. In 1994, the total injury death rate for men was about 6 times higher in Estonia than in Sweden. The death rates for some types of injuries, such as alcohol intoxication and homicide, were many tenfolds higher in Estonia than in Sweden. Injury contributed the most to the widening health gap between the countries, especially in males. The mechanisms of this sudden health deterioration remain to be fully explained. It could be hypothesised that behind the traditional behavioural risk factors, the influence of socio-political factors related to economic and political reconstruction is present. A widespread risk-taking and unhealthy behaviour among Estonians can likely be partly explained as a way of coping with the distress created by the new demands of transition society. An important challenge on the way to improvement is creating the political will among policy-makers to confront the tremendous problems of controlling the factors in society that affect the population's health in Estonia.

    The conception of sustainable resource development worked out under the initiative of the United Nations (UN) actualizes ideas for improving the health of people and the environment. The needs of people are to he addressed and, simultaneously, natural resources preserved. That is ,why ecological and economic expenses are to he integrated and flow sheets of industrial plants are to be reorganized in order to utilize natural resources in a rational way. The association of Estonia with the resolution of the UN Conference on Environmental Development held in Rio de Janeiro and the resolution of the Estonian Parliament concerning The National Program of Sustainable Development require changes in our lifestyle. Chemical education in schools has to support a change in the way of thinking and many concrete subjects can be connected with the problems of sustainable development. Metallic elements get into the environment mostly with fuel combustion ashes. According to various prognoses, fossil fuel resources will last for a thousand years. This means that more and more metallic compounds are thrown into the environment. Dispersion of metals in the air, water bodies and soil is continuously increasing. Finally, they reach the food chain and to the human body. As a result, toxicosis, illnesses, and inadvisable dislocations in organic life may occur. The trend to use ash as a raw material for metal production is considered to have some prospective economically attractive application. This would be one possible way of sustainable resource development to avoid the increase of environmental pollution and increase production of the corresponding metals

    Dairy cows in confinement and pasture-based feeding systems were compared across four spring-calving and three fall-calving replicates for differences in reproduction, mastitis, body weights, and body condition scores. Feeding systems and replicates included both Jersey and Holstein cows. Cows in confinement were fed a total mixed ration, and cows on pasture were supplemented with concentrates and provided baled hay or haylage when pasture supply was limiting. Breeding periods were for 75 d in spring or fall. Reproductive performance did not differ significantly due to feeding system or season. Jerseys had higher conception rates (59.6 vs. 49.5 +/- 3.3%) and higher percentages of cows pregnant in 75 d (78.1 vs. 57.9 +/- 3.9%) than Holsteins. Cows in confinement had 1.8 times more clinical mastitis and eight times the rate of culling for mastitis than did cows on pasture. Jerseys had half as many clinical cases of mastitis per cow as Holsteins. Only 41 +/- 5% of confinement Holsteins remained for a subsequent lactation, starting within the defined calving season compared with 51 +/- 5% of pastured Holsteins and 71 and 72 +/- 5% of Jerseys, respectively. Body weights and condition scores were generally higher for confinement cows than pastured cows, and Jerseys had higher condition scores and lower body weights than Holsteins. In summary, pastured cows had fewer clinical cases of mastitis, lower body condition scores, and lower body weights than confinement cows. Holsteins were less likely to rebreed, had more mastitis, higher culling rates, and lower body condition scores than Jerseys.

    Full Text Available Abstract Background One of the goals of livestock genomics research is to identify the genetic differences responsible for variation in phenotypic traits, particularly those of economic importance. Characterizing the genetic variation in livestock species is an important step towards linking genes or genomic regions with phenotypes. The completion of the bovine genome sequence and recent advances in DNA sequencing technology allow for in-depth characterization of the genetic variations present in cattle. Here we describe the whole-genome resequencing of two Bos taurus bulls from distinct breeds for the purpose of identifying and annotating novel forms of genetic variation in cattle. Results The genomes of a Black Angus bull and a Holstein bull were sequenced to 22-fold and 19-fold coverage, respectively, using the ABI SOLiD system. Comparisons of the sequences with the Btau4.0 reference assembly yielded 7 million single nucleotide polymorphisms (SNPs, 24% of which were identified in both animals. Of the total SNPs found in Holstein, Black Angus, and in both animals, 81%, 81%, and 75% respectively are novel. In-depth annotations of the data identified more than 16 thousand distinct non-synonymous SNPs (85% novel between the two datasets. Alignments between the SNP-altered proteins and orthologues from numerous species indicate that many of the SNPs alter well-conserved amino acids. Several SNPs predicted to create or remove stop codons were also found. A comparison between the sequencing SNPs and genotyping results from the BovineHD high-density genotyping chip indicates a detection rate of 91% for homozygous SNPs and 81% for heterozygous SNPs. The false positive rate is estimated to be about 2% for both the Black Angus and Holstein SNP sets, based on follow-up genotyping of 422 and 427 SNPs, respectively. Comparisons of read depth between the two bulls along the reference assembly identified 790 putative copy-number variations (CNVs. Ten

    Tropical and sub-tropical climates are characterized by high temperature and humidity, during at least part of the year. Consequently, heat stress is common in Holstein cattle and productive and reproductive losses are frequent. Our objectives were as follows: (1) to quantify losses in production and quality of milk due to heat stress; (2) to estimate genetic correlations within and between milk yield (MY) and milk quality traits; and (3) to evaluate the trends of genetic components of tolerance to heat stress in multiple lactations of Brazilian Holstein cows. Thus, nine analyses using two-trait random regression animal models were carried out to estimate variance components and genetic parameters over temperature-humidity index (THI) values for MY and milk quality traits (three lactations: MY×fat percentage (F%), MY×protein percentage (P%) and MY×somatic cell score (SCS)) of Brazilian Holstein cattle. It was demonstrated that the effects of heat stress can be harmful for traits related to milk production and milk quality of Holstein cattle even though most herds were maintained in a modified environment, for example, with fans and sprinklers. For MY, the effect of heat stress was more detrimental in advanced lactations (-0.22 to -0.52 kg/day per increase of 1 THI unit). In general, the mean heritability estimates were higher for lower THI values and longer days in milk for all traits. In contrast, the heritability estimates for SCS increased with increasing THI values in the second and third lactation. For each trait studied, lower genetic correlations (different from unity) were observed between opposite extremes of THI (THI 47 v. THI 80) and in advanced lactations. The genetic correlations between MY and milk quality trait varied across the THI scale and lactations. The genotype×environment interaction due to heat stress was more important for MY and SCS, particularly in advanced lactations, and can affect the genetic relationship between MY and milk quality

    Full Text Available The topic of this article is the literary discourse of Young Estonia; its relations with other important Estonian literary discourses from the beginning of the 20th century, and its relations with colonial cultural discourse. First, I give an overview of the basic positions of the Young Estonians’ literary discourse, the main shapers of which were Friedebert Tuglas, Gustav Suits, later on Johannes Semper as well. Next, I present the basic principles of three Estonian literary discourses from the beginning of the 20th century, which were also important to the Young Estonians: nationalist-naturalistic (close-to-life; socialist/ class-based, and 20th century modernist. The Young Estonians began as nationalists and/or socialists. During the formation of Young Estonia’s discourse at the end of the first and beginning of the second decade of the 20th century, 20th century modernism began, which the Young Estonians regarded first and foremost with irony. The Young Estonians’ literary discourse is a mixture of aestheticism, decadence, symbolism, romanticism, and classicism. The point of departure for the Young Estonian approach to literature was eurocentrism. They took a superior and negative view of existing Estonian literature, which they regarded as having fallen drastically behind Europe. Since it was unable to build on its own foundation, it had to borrow from Europe. The discourse’s understandings of cultural values – theory, reading, knowledge, ready-made culture, derive from the centrality of the dynamic of borrowing. New culture could be created freely, without the support of previous local tradition; it was to be an elite culture, while the writer remained an individualist. Literature was to follow the principle of art for art’s sake; aesthetics and the form of the work of art were basic criteria. The formal ideals of the work of art were classicist: unity, integrity (wholeness, harmony, order, logic, etc. Thirdly, I outline the

    In this study the drinking water of 212 small-scale water supplies, mainly situated in areas with intensive agriculture or fruit-growing, was analysed for uranium. The median uranium concentration amounted to 0.04 μg/lL, the 95th percentile was 2.5 μg/L. The maximum level was 14 μg/L. This sample exceeded the guideline value for uranium in drinking water. The uranium concentration in small-scale water supplies was found to be slightly higher than that in central water works in Schleswig-Holstein. Water containing more than 10 mg/L nitrate showed significantly higher uranium contents. The results indicate that the uranium burden in drinking water from small wells is mainly determined by geological factors. An additional anthropogenic effect of soil management cannot be excluded. Overall uranium concentrations were low and not causing health concerns. However, in specific cases higher concentrations may occur.

    This experiment aimed to compare circulating progesterone (P4), follicular dynamics, and fertility during reuse of intravaginal P4 implants that were sanitized by autoclave or chemical disinfection in lactating Holstein cows submitted to fixed-time artificial insemination (FTAI). For this, 123 primiparous and 226 multiparous cows from 2 farms, averaging (mean ± standard deviation) 163.9 ± 141.9 d in milk, 35.7 ± 11.3 kg of milk/d, and a body condition score of 2.9 ± 0.5, were enrolled in the study. Cows were randomly assigned to 1 of 2 treatments using a completely randomized design and each cow received a reused implant (1.9 g of P4; previously used for 8 d) that was either autoclaved (AUT; n = 177) or chemically disinfected (CHEM; n = 172) on d -10. Also on d -10, cows received 2 mg of estradiol benzoate and 100 μg of GnRH. On d -3, cows received 25 mg of dinoprost (PGF 2α ). A second PGF 2α was given on d -2, along with 1 mg of estradiol cypionate and P4 implant removal. Cows received FTAI on d 0. A subset of cows (n = 143) was evaluated by ultrasound on d -10, -8, -6, -3, -2, 0, and 5 to identify ovarian structures, and blood was sampled on d -10, -3, and -2 for P4 concentrations by RIA. Pregnancy diagnoses were performed at d 32 and 60. Statistical analyses was performed using PROC-MIXED for continuous variables and PROC-GLIMMIX of SAS 9.4 (SAS Institute Inc., Cary, NC) for binomial variables. The treatments did not differ in circulating P4 on d -10 or -3, but P4 was greater on d -2 in CHEM cows. Ovulation to the treatments on d -10 was associated with lower circulating P4 on d -10 (2.0 vs. 3.1 ng/mL) and resulted in greater P4 on d -3 (4.0 vs. 2.4 ng/mL) and more cows with a corpus luteum on d -3 (100 vs. 40%) than nonovulating cows. Cows that ovulated to d -10 treatments were more likely to have a synchronized new follicular wave (97.9 vs. 63.2%) and had an earlier wave emergence (1.9 vs. 2.6 d), resulting in less cows ovulating a persistent follicle

    To explore smoking prevalence and attitudes towards smoking among Estonian physicians in 2002 and 2014. Two self-administered cross-sectional postal surveys were conducted among practising physicians in Estonia. Initial sample consisted of all practising physicians in Estonia. The corrected response rate was 67.8% in 2002 and 53.1% in 2014. Present study sample was restricted to physicians younger than 65 years (n=2549 in 2002, n=2339 in 2014). Age-standardised prevalence of smoking and prevalence of agreement with seven statements concerning attitudes towards smoking was determined. To analyse association of physicians' attitudes towards smoking with study year and smoking status, logistic regression analysis was used. Adjusted ORs of agreement with the seven statements were determined. Corresponding 95% CIs were calculated. The age-standardised prevalence of current smoking among men was 26.8% in 2002 and 15.3% in 2014, among women 10.4% and 5.8%, respectively. Compared with the year 2002, in 2014, prevalence of agreement with statements declaring harmfulness of smoking was higher and prevalence of agreement with statements approving smoking was lower. Adjusted ORs showed that compared with 2002, physicians' attitudes towards smoking were less favourable in 2014, and physicians' attitudes towards smoking were associated with their smoking status. Compared with 2002, the age-standardised smoking prevalence among male and female physicians was lower, and attitudes towards smoking were less approving in 2014. The smoking physicians had more approving attitudes towards smoking than their non-smoking colleagues. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    The present study investigated the contribution of carcass traits on carcass prices of Holstein steers in Korea. Phenotypic data consisted of 76,814 slaughtered Holsteins (1 to 6 yrs) from all over Korea. The means for live body weight at slaughter (BWT), chilled carcass weight (CWT), dressing percentage (DP), quantity grade index (QGI), eye muscle area (EMA), backfat thickness (BF) and marbling score (MS), carcass unit price (CUP), and carcass sell prices (CSP) were 729.0 kg, 414.2 kg, 56.79%, 64.42, 75.26 cm2, 5.77 mm, 1.98, 8,952.80 Korean won/kg and 3,722.80 Thousand Korean won/head. Least squares means were significantly different by various age groups, season of slaughter, marbling scores and yield grades. Pearson’s correlation coefficients of CUP with carcass traits ranged from 0.12 to 0.62. Besides, the relationships of carcass traits with CSP were relatively stronger than those with CUP. The multiple regression models for CUP and CSP with carcass traits accounted 39 to 63% of the total variation, respectively. Marbling score had maximum economic effects (partial coefficients) on both prices. In addition, the highest standardized partial coefficients (relative economic weights) for CUP and CSP were calculated to be on MS and CWT by 0.608 and 0.520, respectively. Path analyses showed that MS (0.376) and CWT (0.336) had maximum total effects on CUP and CSP, respectively; whereas BF contributed negatively. Further sub-group (age and season of slaughter) analyses also confirmed the overall outcomes. However, the relative economic weights and total path contributions also varied among the animal sub-groups. This study suggested the significant influences of carcass traits on carcass prices; especially MS and CWT were found to govern the carcass prices of Holstein steers in Korea. PMID:25049722

    The dairy industry in Pakistan is booming and investors are anxious to fund dairy farms that are using high milk producing (exotic) cattle breeds such as Holsteins that are not native to the country. Unfortunately, the benefits of increased milk production do not provide resistance to pathogens present in regions where the exotic breeds are introduced. Therefore, the current study was conducted to evaluate the economic impact of Theileria annulata on a commercial Holstein dairy farm in the District of Ranjanpur, in the Province of Punjab, Pakistan. The economic impact of T. annulata infection was calculated for cattle with subclinical and clinical theileriosis. Losses were estimated based on milk production, morbidity, mortality and tick control costs (organophosphate sprays). Animals were classified into groups after screening for mastitis, teat abnormality, abnormal parturition, intestinal parasites and hemoparasites (T. annulata, Babesia spp., and Anaplasma spp.). Microscopy was done for hemoparasites and intestinal parasites. PCR was used to confirm microscopic identification of T. annulata. Animals were classified into 3 groups, comprising group A (normal), group B (subclinical theileriosis) and group C (acute theileriosis). Hemoparasites were observed microscopically in 28.7% of cows. Theileria annulata was found in 8% and the herd incidence (new cases) of T. annulata was 2.8%. Milk production, animal rectal temperature and body condition scores of group A with B and C were significantly different (P0.05). The total expenditure incurred due to theileriosis was US $74.98 per animal and 13.83% of total farm costs. Hence theileriosis caused significant economic loss of US $18743.76 (0.02 million) on this Holstein Friesian dairy.

    The SLICK haplotype (http://omia.angis.org.au/OMIA001372/9913/) in cattle confers animals with a short and sleek hair coat. Originally identified in Senepol cattle, the gene has been introduced into Holsteins. The objectives of the current study were to determine (1) whether lactating Holsteins with the slick hair phenotype have superior ability for thermoregulation compared with wild-type cows or relatives not inheriting the SLICK haplotype, and (2) whether seasonal depression in milk yield would be reduced in SLICK cows. In experiment 1, diurnal variation in vaginal temperature in the summer was monitored for cows housed in a freestall barn with fans and sprinklers. Vaginal temperatures were lower in slick-haired cows than in relatives and wild-type cows. In experiment 2, acute responses to heat stress were monitored after cows were moved to a dry lot in which the only heat abatement was shade cloth. The increases in rectal temperature and respiration rate caused by heat stress during the day were lower for slick cows than for relatives or wild-type cows. Moreover, sweating rate was higher for slick cows than for cows of the other 2 types. In experiment 3, effects of season of calving (summer vs. winter) on milk yield and composition were determined. Compared with milk yield of cows calving in winter, milk yield during the first 90 d in milk was lower for cows calving in the summer. However, this reduction was less pronounced for slick cows than for wild-type cows. In conclusion, Holsteins with slick hair have superior thermoregulatory ability compared with non-slick animals and experience a less drastic depression in milk yield during the summer.

    The aim of the authors in this study was to evaluate the relationships between perceived perinatal stress and social support to psychological health outcomes in mothers. A longitudinal, quantitative study was conducted in Geneva, Switzerland on 235 primiparous mothers from September 2010 to January 2012. Data were collected between gestational weeks 37 and 41 (T1), 2 days post-delivery (T2), and at 6 weeks postpartum (T3). Perinatal stress was associated with depressive symptoms (R 2  = 0.223), anxiety (R 2  = 0.242), and a low sense of parental self-efficacy (R 2  = 0.21). However, satisfaction with social support moderated the relationship of stress to the health of mothers. In particular, the authors noted that the more women were provided with support from their partners, the less depressive symptoms and elevated levels of anxiety they reported, even under stressful conditions, while the satisfaction of support from their mothers boosted their sense of competency. Furthermore, satisfaction with emotional support from professionals tempered the stress during the post-partum period (∆R 2  = 0.032; p stress was related to the psychological health of mothers, but social support may modulate these effects. A number of approaches could be implemented to manage this stress.

    With regard to the importance of quality of life in pregnant women, the present study aimed to determine the effect of spouses' educational classes held for primaparous women referring to Hajar hospital on women's quality of life and pregnancy outcomes. This clinical trial was conducted from September 2011 to June 2012 in the clinic of the Hajar university center in Shahrekord. Eligible primiparous women who registered for physiologic delivery educational classes were randomly assigned to study (n = 31) and control (n = 27) groups. In the control group, eight physiologic delivery educational sessions were held. In the study group, in addition to attendance of pregnant women, their husbands also attended the third and the eighth sessions of these classes. Women's quality of life was investigated with SF36 questionnaire and pregnancy outcomes after delivery were investigated. Data were analyzed by t-test and Chi-square test. Before intervention, there was no significant difference between scores of quality of life and demographic characteristics (P > 0.05). After intervention, there was a significant difference only in the dimensions of mental health, hugging time, kissing, and breast feeding between the study and control groups (P 0.05). Educational classes held for the pregnant women's husbands during pregnancy can be efficient in promotion of pregnant women's quality of life, especially in improving their mental health.

  5. Holstein-Friesian milk performance in organic farming in North Spain: Comparison with other systems and breeds

    Directory of Open Access Journals (Sweden)

    2017-04-01

    Full Text Available Organic systems are highly dependent on the environment and require animals well adapted to local conditions. In Spain, organic dairy farmers are not satisfied with the productive performance of their herds and ask for technical advice to obtain suitable animals for organic systems. The milk productive performance (milk yield, nutritional composition, and somatic cell count of Holstein-Friesian cows in organic farming in North Spain compared with conventional farms has been analysed. When breed diversity was present in the same organic farm, Holstein-Friesian milk performance was compared with other breeds and/or crosses. Holstein-Friesian cows in organic farming produce slightly less milk than grazing conventional cows, but milk was similar in composition and somatic cell count across systems. The limited data from organic farms where breed diversity exists indicate that Holstein-Friesian cows produce numerically more milk than other breeds and crosses but with statistically lower protein content. Considering that in Spain organic milk production is mostly used for liquid milk consumption and that the payment system is based only on milk volume, Holstein-Friesian cows would better fit the farmer interests than other breeds or crosses. However, in addition to productive performance, reproductive efficiency, animal health and consumer’s preferences should be fully considered when selecting a breed for organic production. If Holstein-Friesian was the selected breed, efforts should be made to identify cows within the breed that are best adapted to organic conditions. New productive, reproductive, nutritional and economic studies would be needed to develop a genetic merit index for organic systems.

    A total of 30,190 first-parity Danish Holstein cows housed in free stalls or tie stalls were analyzed to quantify to what degree genotype by housing interaction existed for 21 conformation and 2 workability traits. Each trait measured in different housing systems was treated as 2 separate traits...... in a bivariate animal model. Genetic correlations between the 2 traits as well as differences in genetic and residual variance were used as measurements of whether or not genotype by housing interaction occurred. Genetic correlations were in general close to unity (>0.9), except for body width (0.87 +/- 0...

    An 8-year-old Holsteiner gelding was presented for evaluation of anorexia, obtundation, icterus, and mild colic signs of 48 hours duration. History, physical examination, and initial diagnostics were suggestive of hepatic disease and encephalopathy. Microcystin toxicosis was suspected based on historical administration of a cyanobacteria supplement, associated serum biochemistry abnormalities, and characteristic histopathological changes. Microcystin contamination was confirmed in both supplement containers fed to the horse. Fulminant hepatic failure and encephalopathy progressed resulting in euthanasia. Necropsy findings were consistent with microcystin induced liver failure. Copyright © 2016 The Authors.

    The one-dimensional Holstein model of spinless fermions interacting with dispersionless phonons is solved by using a Bethe ansatz in analogue to that for the one-dimensional spinless Fermi-Hubbard model. Excitation energies and the corresponding wavefunctions of the model are determined by a set of partial differential equations. It is shown that the model is, at least, quasi-exactly solvable for the two-site case, when the phonon frequency, the electron-phonon coupling strength and the hopping integral satisfy certain relations. As examples, some quasi-exact solutions of the model for the two-site case are derived. (letter to the editor)

    In order to perform retrospective estimations of radiation doses seven years after the nuclear accident in Chernobyl, the frequencies of chromosomal aberrations in the peripheral blood lymphocytes of individuals living in contaminated areas around Chernobyl and the Estonian clean-up workers were determined. The first study group composed of 45 individuals living in four areas (i.e. Rechitsa, Komsomolski, Choiniki and Zaspa) in the vicinity (80-125 km) of Chernobyl and 20 individuals living in Minsk (control group - 340 km from Chernobyl). The second study group (Estonian clean-up workers) composed of 26 individuals involved in cleaning up the Chernobyl for a different period of time (up to 7 months) and a matched control group consisting of 9 probands. Unstable aberrations (dicentrics and rings) were scored in Giemsa stained preparations and stable aberrations (translocations) were analyzed using chromosome specific DNA libraries and fluorescence in situ hybridization (FISH) technique. For both study groups the estimated average dose is between 0,1-0,4 Gy. Among the people living in the contaminated areas in the vicinity of Chernobyl, a higher frequency of numerical aberrations (i.e. trisomy, hyper diploidy) was evident

    Full Text Available The objective of this study was to evaluate the effect of the breed of the oocyte donor cow and bull (Holstein versus Gyr on in vitro production (IVP parameters of bovine embryos comparing the mean number of recovered oocytes and oocytes suitable for culture, the rate of suitable oocytes, and cleavage and blastocyst rates. Data from 1,000 follicular aspiration sessions (OPU, including 500 in donor cows of the Holstein breed and 500 of the Gyr breed, were collected. The results were analyzed by the unpaired Student t-test and chi-square test, adopting a level of significance of 5%. The mean number and standard deviation of recovered oocytes and oocytes suitable for culture were 15.1±13.0 and 8.7±7.6 for the Holstein breed and 15.5±11.9 and 9.1±7.9 for the Gyr breed. The rates of suitable oocytes were 57.7% and 58.5% for Holstein and Gyr breeds, respectively. A significant difference between breeds was observed for the number of oocytes suitable for culture (P<0.05, but not for the number of recovered oocytes or rates of suitable oocytes (P>0.05.

    Full Text Available Com o objetivo de avaliar a produção de leite, o leite residual e as respostas comportamentais de vacas Holandesas durante a ordenha, 14 vacas foram ordenhadas mecanicamente, duas vezes ao dia e avaliadas durante as seis primeiras semanas de lactação. A produção leiteira foi mensurada diariamente e o volume de leite residual, semanalmente. A temperatura de corpo (região das costelas, úbere e tetos e a frequência respiratória foram mensuradas duas vezes por semana. O comportamento dos animais na sala de ordenha foi registrado duas vezes por semana em etogramas e pelas entrevistas com os ordenhadores. Nas primeiras semanas de lactação, a porcentagem de coices, sobrepassos, derrubadas de teteira, micções e vocalizações observadas foram maiores para as vacas primíparas (p 0,05, sugerindo que houve adaptação de ambos os grupos ao ambiente de ordenha.Aiming to compare milk yield, residual milk and behavioral responses of Holstein cows during milking, fourteen experimental cows were mechanically milked twice a day, and evaluated during the first six weeks of lactation. Milk yield was measured daily, and residual milk volume weekly. Body (ribs region, udder and teat temperatures and respiratory frequency were measured twice a week. Animal behavior at the milking parlor was registered using ethograms and interviews with the milkers. During the first weeks of lactation, a higher percentage of kicks, over-steps, milking cups being knocked down, urinations and vocalizations in primiparous cows (p 0.05, which suggests adaptation of both groups to the milking environment.

    The histidine ammonia-lyse gene (HAL) encodes the histidine ammonia-lyase, which catalyzes the first reaction of histidine catabolism. In our previous genome-wide association study in Chinese Holstein cows to identify genetic variants affecting milk production traits, a SNP (rs41647754) located 357 bp upstream of HAL, was found to be significantly associated with milk yield and milk protein yield. In addition, the HAL gene resides within the reported QTLs for milk production traits. The aims of this study were to identify genetic variants in HAL and to test the association between these variants and milk production traits. Fifteen SNPs were identified within the regions under study of the HAL gene, including three coding mutations, seven intronic mutations, one promoter region mutation, and four 3'UTR mutations. Nine of these identified SNPs were chosen for subsequent genotyping and association analyses. Our results showed that five SNP markers (ss974768522, ss974768525, ss974768531, ss974768533 and ss974768534) were significantly associated with one or more milk production traits. Haplotype analysis showed that two haplotype blocks were significantly associated with milk yield and milk protein yield, providing additional support for the association between HAL variants and milk production traits in dairy cows (P HAL gene and milk production traits in Chinese Holstein cows, indicating the potential role of HAL variants in these traits. These identified SNPs may serve as genetic markers used in genomic selection schemes to accelerate the genetic gains of milk production traits in dairy cattle.

    Full Text Available The effect of Bacillus subtilis natto on hindgut fermentation and microbiota of early lactation Holstein dairy cows was investigated in this study. Thirty-six Holstein dairy cows in early lactation were randomly allocated to three groups: no B. subtilis natto as the control group, B. subtilis natto with 0.5×1011 cfu as DMF1 group and B. subtilis natto with 1.0×1011 cfu as DMF2 group. After 14 days of adaptation period, the formal experiment was started and lasted for 63 days. Fecal samples were collected directly from the rectum of each animal on the morning at the end of eighth week and placed into sterile plastic bags. The pH, NH3-N and VFA concentration were determined and fecal bacteria DNA was extracted and analyzed by DGGE. The results showed that the addition of B. subtilus natto at either treatment level resulted in a decrease in fecal NH3-N concentration but had no effect on fecal pH and VFA. The DGGE profile revealed that B. subtilis natto affected the population of fecal bacteria. The diversity index of Shannon-Wiener in DFM1 decreased significantly compared to the control. Fecal Alistipes sp., Clostridium sp., Roseospira sp., beta proteobacterium were decreased and Bifidobacterium was increased after supplementing with B. subtilis natto. This study demonstrated that B. subtilis natto had a tendency to change fecal microbiota balance.

    Motivated by the current interest in the understanding of the Mott insulators away from half-filling, observed in many perovskite oxides, we study the Mott metal-insulator transition in the doped Hubbard-Holstein model using the Hartree-Fock mean field theory. The Hubbard-Holstein model is the simplest model containing both the Coulomb and the electron-lattice interactions, which are important ingredients in the physics of the perovskite oxides. In contrast to the half-filled Hubbard model, which always results in a single phase (either metallic or insulating), our results show that away from half-filling, a mixed phase of metallic and insulating regions occurs. As the dopant concentration is increased, the metallic part progressively grows in volume, until it exceeds the percolation threshold, leading to percolative conduction. This happens above a critical dopant concentration δc, which, depending on the strength of the electron-lattice interaction, can be a significant fraction of unity. This means that the material could be insulating even for a substantial amount of doping, in contrast to the expectation that doped holes would destroy the insulating behavior of the half-filled Hubbard model. While effects of fluctuation beyond the mean field remain an open question, our results provide a starting point for the understanding of the density-driven metal-insulator transition observed in many complex oxides.

    Full Text Available Aim: The aim of this study was to investigate 10 cases of bovine ocular squamous cell carcinoma (OSCC diagnosed in Holstein or Holstein-crosses cows. Materials and Methods: The investigation was performed exclusively in OSCC cases diagnosed in the State of Parana and Santa Catarina. A combination of two previously existing histopathological classifications systems was used. The tissue samples were tested for immunoexpression of p53 and p16 and polymerase chain reaction (PCR for bovine herpesvirus and papillomavirus. Results: A positive correlation between number of mitotic figures and tissue invasion was found. Anaplasia parameters did not correlate well with tumor invasion of deeper tissues and mitotic counts. Six of 10 OSCC cases were in animals with heavily pigmented eyes. Immunoexpression of p53 and p16 was observed in 3 cases each. Bovine herpesvirus and papillomavirus were not detected by PCR. Conclusion: Our results indicate that OSCC occurrence is most likely multifactorial with genetic, phenotypic, and environmental influences contributing to the pathogenesis of the disease.

    In three experiments patterns of water turnover and body composition estimated by deuterium oxide were studied in Holstein cows. In the first experiment, four lactating cows were infused with deuterium oxide, and blood samples were taken during 4-d collection. Milking was stopped; cows were reinfused with deuterium oxide and resampled. Slopes of deuterium oxide dilution curves indicated lactating cows turned water over more rapidly than nonlactating cows. In the second experiment with the same four cows, during 4-d collection, deuterium oxide concentrations in milk, urine, and feces showed dilution patterns similar to deuterium oxide in blood. Sampling milk may be an alternative to sampling blood. In the third experiment, 36 Holstein cows were fed 55, 65, or 75% alfalfa, smooth bromegrass, or equal parts of each forage as total mixed rations; remaining portions of rations were a grain mixture. Body composition was estimated at -1, 1, 2, 3, 4, and 5 mo postpartum. Empty body water, protein, mineral, fat, and fat percentage decreased from prepartum to postpartum. First calf heifers contained less empty body water, protein, and mineral than older cows. Cows fed diets with 55% forage had more body fat than those fed diets with 75% forage. Cows fed alfalfa-based diets had more gastrointestinal fill regardless of grain than cows fed diets that contained alfalfa and smooth bromegrass. Gastrointestinal fill of cows increased from prepartum to 5 mo postpartum

    Records of Holstein cows from March 1992 to April 2008 from 194 large herds and comprising from 402,716 records for productive traits to 178,344 records of somatic cell count were used to study the effect of calf sex in different parities and calving season on the subsequent productive, reproductive and health traits in Holstein cows. T-test procedure of SAS software was used to investigate the effect of calf sex and season of calving on aforementioned traits. Cows with female calves had higher milk and fat yield, persistency of milk and fat yield and longer lactation length, while cows that gave birth to male calves had shorter calving interval and longer productive life. Also, cows with female calves had higher milk yield per day of lactation in the first two parities, but there was no difference in milk yield per day of lactation for parities ≥ 3. There was no relationship among mean somatic cell count and sex of born calf. Fall calves had the highest adjusted milk yield and milk yield per day of lactation, however, winter calves had the longest lactation lengthand productive life and the highest somatic cell count. Results from this study demonstrate that it seems necessary to consider the effect of calf sex on aforementioned traits when making decision to use sexed semen or conventional semen. (Author)

    The objective of this study was to evaluate the effect of dystocia on the reproductive performance and functional longevity in Iranian Holsteins. Data consisted of 1 467 064 lactation records of 581 421 Holstein cows from 3083 herds which were collected by the Animal Breeding Center of Iran from April 1987 to February 2014. Reproduction traits in this study included interval from first to second calving, days open and days from first calving to first service. The generalized linear model was used for the statistical analysis of reproductive traits. Survival analysis was performed using the Weibull proportional hazards models to analyse the impact of dystocia on functional longevity. The incidence of dystocia had an adverse effect on the reproductive performance of dairy cows. Therefore, reproductive traits deteriorated along with increase in dystocia score (p dystocia (p 33 months had the greatest risk (p dystocia had important negative effects on the reproductive performance and functional longevity in dairy cows, and it should be avoided as much as possible to provide a good perspective in the scope of economic and animal welfare issues in dairy herds.

    Full Text Available The objective of this work was to obtain prevalence estimates of cloudy vaginal mucus in artificially inseminated Holstein cows raised under intense heat, in order to assess the effect of meteorological conditions on its occurrence during estrus and to determine its effect on conception rate. In a first study, an association was established between the occurrence of cloudy vaginal mucus during estrus and the conception rate of inseminated cows (18,620 services, raised under intense heat (mean annual temperature of 22°C, at highly technified farms, in the arid region of northern Mexico. In a second study, data from these large dairy operations were used to assess the effect of meteorological conditions throughout the year on the occurrence of cloudy vaginal mucus during artificial insemination (76,899 estruses. The overall rate of estruses with cloudy vaginal mucus was 21.4% (16,470/76,899; 95% confidence interval = 21.1-21.7%. The conception rate of cows with clean vaginal mucus was higher than that of cows with abnormal mucus (30.6 vs. 22%. Prevalence of estruses with cloudy vaginal mucus was strongly dependent on high ambient temperature and markedly higher in May and June. Acceptable conception rates in high milk-yielding Holstein cows can only be obtained with cows showing clear and translucid mucus at artificial insemination.

    Full Text Available The objective of this study was to show the risk factors affecting the conception rate in Holstein heifers after synchronization of estrus. A total of 275 Holstein heifers housed in a free barn were used for the experiment. The herd was visited regularly at four week intervals for synchronization of estrus using Heatsynch and CIDR-Heatsynch protocols. A group of four to 14 animals, depending on the availability, were referred to the experiment at each visit. Estrus induction rates in the two protocols were 93.9% and 94.9%, respectively. There was no difference in the conception rate between the two protocols. Conception rate after artificial insemination (AI or embryo transfer (ET were 46.3% and 51.4%, respectively. The risk factors affecting conception rate in heifers were daily weight gain (odds ratio [OR]= 4.673; P= 0.036 and body condition score (BCS (OR= 3.642; P= 0.018. Furthermore, estrus synchronization protocol (OR= 1.774; P= 0.083 and the absence of corpus luteum (CL at the initiation of treatment (OR= 0.512; P= 0.061 had a tendency to affect the conception rate, while age (OR= 0.715; P= 0.008 was a protective factor to conception rate.  In conclusion, positive daily weight gain before AI or ET, higher BCS, younger age, and the presence of CL at the initiation of estrus synchronization in dairy heifers increased the likelihood to conceive.

  7. Finite temperature dynamics of a Holstein polaron: The thermo-field dynamics approach

    2017-12-01

    Combining the multiple Davydov D2 Ansatz with the method of thermo-field dynamics, we study finite temperature dynamics of a Holstein polaron on a lattice. It has been demonstrated, using the hierarchy equations of motion method as a benchmark, that our approach provides an efficient, robust description of finite temperature dynamics of the Holstein polaron in the simultaneous presence of diagonal and off-diagonal exciton-phonon coupling. The method of thermo-field dynamics handles temperature effects in the Hilbert space with key numerical advantages over other treatments of finite-temperature dynamics based on quantum master equations in the Liouville space or wave function propagation with Monte Carlo importance sampling. While for weak to moderate diagonal coupling temperature increases inhibit polaron mobility, it is found that off-diagonal coupling induces phonon-assisted transport that dominates at high temperatures. Results on the mean square displacements show that band-like transport features dominate the diagonal coupling cases, and there exists a crossover from band-like to hopping transport with increasing temperature when including off-diagonal coupling. As a proof of concept, our theory provides a unified treatment of coherent and incoherent transport in molecular crystals and is applicable to any temperature.

    Full Text Available The aim of the study was to determine the relationship between the behaviour of Holstein-Friesian and Simmental bulls and the quality of their semen. A total of 76 breeding bulls of the Holstein-Friesian and dual-purpose Simmental breeds were investigated. Analysis was made of the response of bulls to humans and other bulls, facial hair whorl position and length, scrotal circumference, and semen characteristics (mean ejaculate volume, mean sperm concentration, and sperm wave motion. The age and breed of the bulls had a statistically significant effect on semen quality, scrotal circumference and the animals response to an unfamiliar human (Plt,0.05, Plt,0.01. The coefficients of correlation between the bull s response to a handler and to other bulls averaged 0.73. In general, only weak correlations were found between behavioural traits of the bulls and quality of their semen. It is worth noting a good correlation (r=0.50; Plt;0.05 between hair whorl position and sperm concentration in Simmental bulls.

    Ecological and economic concerns drive the need to improve feed utilization by domestic animals. Residual feed intake (RFI) is one of the most acceptable measures for feed efficiency (FE). However, phenotyping RFI-related traits is complex and expensive and requires special equipment. Advances in marker technology allow the development of various DNA-based selection tools. To assimilate these technologies for the benefit of RFI-based selection, reliable phenotypic measures are prerequisite. In the current study, we identified single nucleotide polymorphisms (SNPs) associated with RFI phenotypic consistency across different ages and diets (named RFI 1-3), using DNA samples of high or low RFI ranked Holstein calves. Using targeted sequencing of chromosomal regions associated with FE- and RFI-related traits, we identified 48 top SNPs significantly associated with at least one of three defined RFIs. Eleven of these SNPs were harbored by the fatty acid binding protein 4 (FABP4). While 10 significant SNPs found in FABP4 were common for RFI 1 and RFI 3, one SNP (FABP4_5; AHolstein breed, following a larger-scale validation. Copyright © 2016 the American Physiological Society.

Were used 36 Holstein calves, from the same herd, with an average of 192 days and an average body weight of 221kg age. The experimental diets consisted of: T1: 100% concentrate diet; T2: 55% concentrate diet + corn silage; and T3: 55% concentrate diet + oat hay, and six replicates, where each replicate was a stall with two animals. Was no significant difference between treatments, and the treatment consists of the 100% concentrate diet had higher performance results with an average daily gain of 1.350 kg day-1; and feed conversion of 5.28 dry matter intake of 6.84. We evaluated also the 100% diet also influenced the feeding behavior, and the time for rumination, food consumption and water intake are respectively 2.75; 1.14; 0.15 hours day-1. The digestibility of dry matter was also a significant difference to the diet 100%, and this was around 76.37%. The diet showed 100% concentrate in terms of performance, an interesting alternative for termination of Holstein steers.

    The objectives of the present study were: 1) to investigate variation in the genetic component of heat stress for nonreturn rate at 56 days after first artificial insemination (NR56); 2) to identify and characterize the genotype by environment interaction (G × E) due to heat stress for NR56 of Brazilian Holstein cattle. A linear random regression model (reaction norm model) was applied to 51,748 NR56 records of 28,595 heifers and multiparous cows. The decline in NR56 due to heat stress was more pronounced in milking cows compared to heifers. The age of females at first artificial insemination and temperature-humidity index (THI) exerted an important influence on the genetic parameters of NR56. Several evidence of G × E on NR56 were found as the high slope/intercept ratio and frequent intersection of reaction norms. Additionally, the genetic correlation between NR56 at opposite extremes of the THI scale reached estimates below zero, indicating that few of the same genes are responsible for NR56 under conditions of thermoneutrality and heat stress. The genetic evaluation and selection for NR56 in Holstein cattle reared under (sub)tropical conditions should therefore take into consideration the genetic variation on age at insemination and G × E due to heat stress.

    We have previously found substantial animal-to-animal and age-dependent variation in the response of Holstein fibroblast cultures challenged with LPS. To expand on this finding, fibroblast cultures were established from dairy (Holstein) and beef (Angus) cattle and challenged with LPS to examine breed-dependent differences in the innate immune response. Global gene expression was measured by RNA-Seq, while an epigenetic basis for expression differences was examined by methylated CpG island recovery assay sequencing (MIRA-Seq) analysis. The Holstein breed displayed a more robust response to LPS than the Angus breed based on RNA-Seq analysis of cultures challenged with LPS for 0, 2, and 8 h. Several immune-associated genes were expressed at greater levels (FDR Angus fibroblasts, and two of these regions fell within the promoter region (-2500 to +500 bp of the transcription start site) of the genes NTRK2 and ADAMTS5. Fibroblasts isolated from Holstein cattle display a more robust response to LPS in comparison to cultures from Angus cattle. Different selection strategies and management practices exist between these two breeds that likely give rise to genetic and epigenetic factors contributing to the different immune response phenotypes.

    Full Text Available Abstract Background Complex vertebral malformation (CVM and bovine leukocyte adhesion deficiency (BLAD are two autosomal recessive lethal genetic defects frequently occurring in Holstein cattle, identifiable by single nucleotide polymorphisms. The objective of this study is to develop a rapid and reliable genotyping assay to screen the active Holstein sires and determine the carrier frequency of CVM and BLAD in Chinese dairy cattle population. Results We developed real-time PCR-based assays for discrimination of wild-type and defective alleles, so that carriers can be detected. Only one step was required after the DNA extraction from the sample and time consumption was about 2 hours. A total of 587 Chinese Holstein bulls were assayed, and fifty-six CVM-carriers and eight BLAD-carriers were identified, corresponding to heterozygote carrier frequencies of 9.54% and 1.36%, respectively. The pedigree analysis showed that most of the carriers could be traced back to the common ancestry, Osborndale Ivanhoe for BLAD and Pennstate Ivanhoe Star for CVM. Conclusions These results demonstrate that real-time PCR is a simple, rapid and reliable assay for BLAD and CVM defective allele detection. The high frequency of the CVM allele suggests that implementing a routine testing system is necessary to gradually eradicate the deleterious gene from the Chinese Holstein population.

    Full Text Available Abstract Background Hereditary spastic paraplegia (HSP is a clinically and genetically heterogeneous disorder that can be an autosomal-dominant, autosomal-recessive, or X-linked disease. The most common autosomal-dominant form of the disease derives from mutations in the SPAST gene. Methods The aim of this study was to analyze 49 patients diagnosed with HSP from the Estonian population for sequence variants of the SPAST gene and to describe the associated phenotypes. Healthy control individuals (n = 100 with no family history of HSP were also analyzed. All patient samples were screened using denaturing high performance liquid chromatography (DHPLC and multiplex ligation-dependent probe amplification (MLPA assay. Samples with abnormal DHPLC and MLPA profiles were sequenced, with the same regions sequenced in control samples. Results Sequence variants of SPAST were identified in 19/49 HSP patients (38.8%, twelve among them had pathogenic mutations. Within the latter group there was one sporadic case. Eight patients had pure, and four - complex HSP. The twelve variants were identified: seven pathogenic (c.1174-1G>C, c.1185delA, c.1276C>T, c.1352_1356delGAGAA, c.1378C>A, c.1518_1519insTC, c.1841_1842insA and five non-pathogenic (c.131C>T, c.484G>A, c.685A>G, c.1245+202delG, c.1245+215G>C. Only 2 of these mutations had previously been described (c.131C>T, c.1245+202delG. Three mutations, c.1174-1G>C, c.1276 C>T, c.1378C>A, showed intrafamilial segregation. Conclusion This study identified new variants of the SPAST gene which included benign missense variants and short insertions/deletions. No large rearrangements were found. Based on these data, 7 new pathogenic variants of HSP are associated with clinical phenotypes.

    Patient-initiated elective Caesarean section (PIECS) is increasingly prevalent and is emerging as an urgent issue for individual maternity practitioners, hospitals, and policy makers, as well as for maternity patients. This qualitative study sought to explore women's experiences of the decision-making process leading to elective operative delivery without medical indication. We conducted 17 exploratory qualitative in-depth interviews with primiparous women who had undergone a patient-initiated elective Caesarean section in the absence of any medical indication. The study took place in five hospitals (three urban, two semi-rural) in British Columbia. The findings revealed three themes within the process of women deciding to have a Caesarean section: the reasons for their decision, the qualities of the decision-making process, and the social context in which the decision was made. The factors that influenced a patient-initiated request for delivery by Caesarean section in participants in this study were diverse, culturally dependent, and reflective of varying degrees of emotional and evidence-based influences. PIECS is a rare but socially significant phenomenon. The a priori decision making of some women choosing PIECS does not follow the usual diagnosis-intervention trajectory, and the care provider may have to work in reverse to ensure that the patient fully understands the risks and benefits of her decision subsequent to the decision having been made, while still ensuring patient autonomy. Results from this study provide a context for a woman's request for an elective Caesarean section without medical indication, which may contribute to a more efficacious informed consent process.

  9. Identification of differentially expressed genes in sexed pig embryos during post-hatching development in primiparous sows exposed to differing intermittent suckling and breeding strategies

    Full Text Available The aim of commercial pig breeding programs is to maximize the number of pigs produced per sow per year. Given that sows exhibit an estrus during lactation is a potential means of increasing productivity of a pig breeding herd without reducing in lactation length, conventionally, weaning of piglets at a relatively young age is often related to post-weaning piglet performance which compromises piglet welfare. Therefore, intermittent suckling (IS is a management technique in which lactating sows are separated from their piglets for a fixed period of the days and allowing sows to continue nursing piglets while exhibiting estrus and being breed during lactation, thereby promoting both piglet well-being and sow reproductive performance [1]. For this study, primiparous sows (PP were exposed to 28 day (D28 lactation with intermittent suckling (IS during the final week prior to weaning. The sows detected to be in estrus during lactation were either bred at this first estrus (FE during lactation (IS21FE, or were “skipped” and bred at their second estrus which occurred after final weaning at D28 (IS21SE. Despite the benefits of IS, the effects of the maternal physiology related to breeding during lactation on embryonic transcriptome are largely unknown. Recent advances in the ability to assess embryonic gene expression in both sexes have made these analyses possible. Here, we describe the experimental procedures of two color microarray analyses and annotation of differentially expressed (DE genes in detail corresponding to data deposited at NCBI in the Gene Expression Omnibus under accession number GSE53576 and GSE73020 for day 9 embryos (D9E and day 30 embryos (D30E respectively. Although only a few DE genes were discovered between IS21FE and IS21SE in both sexes from D9E or D30E, the raw data are still valuable for future use to understand the gene expression profiling from two different developmental stages.

    Full Text Available Until recently the museum phenomenon as the valuator of the indigenous culture in the context of the awakening national consciousness has received little attention. The evolution of the idea of the Estonian National Museum (ENM and its realization reflects the story of the Estonian people maturing into a nation. The museum was founded by a few dedicated persons and it took a long time before the general public recognised it as the museum for the Estonian people. The main purpose of this research is to ascertain how relations developed between the public and the museum in its initial years and what were the museum strategies in declaring its objectives. After the official foundation of the ENM in 1909 the museum narrative can be divided into two main parts. First, work inside the museum, the compilation and arrangement of collections. This was, above all, the work of the collection committee and organizing heritage collection trips. Collections constitute the basis of a museum – therefore the primary and most important task of the established museum was the collection of heritage items. The collections were started immediately after the foundation of the museum; within the first ten years approximately 20,000 items were collected, approximately two thirds of the items in the years 1911–1913. The phenomenon that a museum where people worked mainly without a salary for the benefit of their homeland, with the set aim to empty the whole of Estonia of heritage items parish by parish and succeeded in engaging dozens and dozens of people for this work, is probably exceptional in world history. As a result, the museum acquired not only voluminous but also valuable item collections, which reached the museum before the devastating First World War. The timing was favourable. There were enough old artefacts left, although most collectors complained in their diaries that there was nothing interesting to be found any more. However, the majority of the

    Full Text Available ABSTRACT Zebu and Holstein x Zebu crossbred have low incidence of uterine infection when compared to Holstein cows. Resistance to uterine infections may be associated with the ability to recognize invading microorganisms. Endometrial transcription of microbial molecular patterns receptors has been investigated in the postpartum period of Holstein cows, but it is completely unknown in Zebu or Holstein x Zebu cows. In this study, 9 Gyr and 12 F1 Holstein x Gyr cows were submitted to endometrial biopsies at the first and seventh days postpartum, with the objective to measure transcription levels of toll-like receptors (TLRs 1/6, 2, 4, 5, and 9; nucleotide-binding oligomerization domain (NOD-like receptors 1 and 2; and coreceptors cluster of differentiation 14 (CD14 and myeloid differentiation protein-2 (MD-2. There was a significant (P<0.05 decrease in transcription of TLR5 in Gyr, and an increase in transcription of TLR9 in F1 cows, between the first and seventh day postpartum. Both groups had low incidences of uterine infections up to 42 days postpartum. Uterine involution completed at 27.7 ± 10.1 and 25.1 ± 4.7 days postpartum for Gyr and F1 cows, respectively. In Gyr cows, higher transcription levels of TLR1/6 and NOD1 correlated to a longer period required for uterine involution. In F1 cows, lower levels of TLR1/6, TLR2 and NOD2 correlated to a longer period required for uterine involution. In conclusion, some pathogen recognition receptors associated significantly with the time required for uterine involution in Gyr and F1 cows.

    Full Text Available The objective of this study was to determine beef production traits of purebred Holstein-Friesian (Hol and Hol×beef breed crossbred bulls. The data collected from slaughterhouses included observations of 87323 purebred Hol, 783 Hol×Aberdeen angus (Hol×Ab, 621 Hol×Blonde d’Aquitaine (Hol×Ba, 562 Hol×Charolais (Hol×Ch, 349 Hol×Hereford (Hol×Hf, 1691 Hol×Limousin (Hol×Li and 570 Hol×Simmental (Hol×Si bulls. For estimating valuable cuttings also a separate dataset was collected and included observations of 8806 purebred Hol, 57 Hol×Ab, 29 Hol×Ba, 22 Hol×Ch, 15 Hol×Hf, 111 Hol×Li and 58 Hol×Si bulls. Crossbreeding Hol cows with late maturing breeds (Ba, Ch, Li, Si had favorable effects on carcass gain, conformation and proportion of high value joints of the progeny when compared to purebred Hol bulls. No advantages in proportion of valuable cuttings seemed to be obtained by crossbreeding with Ab or Hf breeds, while the improvements in gain and conformation were intermediate compared to the late maturing crossbreds.

    Full Text Available Objective Calving ease (CE is a complex reproductive trait of economic importance in dairy cattle. This study was aimed to investigate the genetic merits of CE for Holsteins in Korea. Methods A total of 297,614 field records of CE, from 2000 to 2015, from first parity Holstein heifers were recorded initially. After necessary data pruning such as age at first calving (18 to 42 mo, gestation length, and presence of sire information, final datasets for CE consisted of 147,526 and 132,080 records for service sire calving ease (SCE and daughter calving ease (DCE evaluations, respectively. The CE categories were ordered and scores ranged from CE1 to CE5 (CE1, easy; CE2, slight assistance; CE3, moderate assistance; CE4, difficult calving; CE5, extreme difficulty calving. A linear transformation of CE score was obtained on each category using Snell procedure, and a scaling factor was applied to attain the spread between 0 (CE5 and 100% (CE1. A sire-maternal grandsire model analysis was performed using ASREML 3.0 software package. Results The estimated direct heritability (h2 from SCE and DCE evaluations were 0.11±0.01 and 0.08±0.01, respectively. Maternal h2 estimates were 0.05±0.02 and 0.04±0.01 from SCE and DCE approaches, respectively. Estimates of genetic correlations between direct and maternal genetic components were −0.68±0.09 (SCE and −0.71±0.09 (DCE. The average direct genetic effect increased over time, whereas average maternal effect was low and consistent. The estimated direct predicted transmitting ability (PTA was desirable and increasing over time, but the maternal PTA was undesirable and decreasing. Conclusion The evidence on sufficient genetic variances in this study could reflect a possible selection improvement over time regarding ease of calving. It is expected that the estimated genetic parameters could be a valuable resource to formulate sire selection and breeding plans which would be directed towards the reduction of

    The main objective of this study was to assess the genetic parameters of subclinical disorders associated with subclinical hypocalcemia, hypophosphatemia, subclinical hypomagnesemia, hypokalemia, and hyperphosphatemia, as well as major clinical diseases after calving in Holstein cows. The secondary objective was to estimate the associated genetic and phenotypic correlations among these subclinical and clinical conditions after calving in Holstein cows. The study was conducted in 9dairy herds located in Northern Greece. None of the herds used any kind of preventive measures for milk fever (MF). A total of 1,021 Holstein cows with pedigree information were examined from November 2010 until November 2012. The distribution across parities was 466 (parity 1), 242 (parity 2), 165 (parity 3), and 148 (parity 4 and above) cows. All cows were subjected to a detailed clinical examination and blood was sampled on d 1, 2, 4, and 8 after calving. Serum concentrations of Ca, P, Mg, and K were measured in all samples, whereas β-hydroxybutyrate (BHB) was measured only for d 8. The final data set included 4,064 clinical and 16,848 biochemical records (4,020 Ca, 4,019 P, 4,020Mg, 3,792K, and 997 BHB). Data of 1,988 observations of body condition score at d 1 and 8 were also available. All health traits were analyzed with a univariate random regression model. The genetic analysis for macromineral-related disorders included 986 cows with no obvious signs of MF (35 cows with MF were excluded). Analysis for other health traits included all 1,021 cows. A similar single record model was used for the analysis of BHB. Genetic correlations among traits were estimated with a series of bivariate analyses. Statistically significant daily heritabilities of subclinical hypocalcemia (0.13-0.25), hypophosphatemia (0.18-0.33), subclinical hypomagnesemia (0.11-0.38), and hyperphosphatemia (0.14-0.22) were low to moderate, whereas that of hypokalemia was low (0.08-0.10). The heritability of body

    Since very little information exists about the topic; in this experiment we compare, in a long-term finishing program, the growth-performance responses and carcass characteristics of Holstein steers where non-structural carbohydrate concentration of the diet is reduced from 64% to 51% (dry matter basis). Sixty Holstein steer calves (129±2.2 kg) were blocked by initial weight into five groups and randomly assigned within weight groupings to 10 pens. Calves were fed with a steam-flaked corn-based finishing diets containing 51% higher fiber (HF) or 64% lower fiber (LF) nonstructural carbohydrates. Non-structural carbohydrates concentrations were manipulated substituting dried distiller grain with solubles and alfalfa hay for flaked corn. Cattle were weighed every 112 days and at the end of the experiment (day 308) when the cattle were harvested and carcass characteristics were evaluated. Steers fed the HF diet showed improvement (8.8%) in average daily gain (ADG) during the initial 112-d period. This effect was followed by a numerical trend for greater ADG throughout the remainder of the study so that overall ADG tended to be greater (4.9%, p = 0.06) for the HF than for LF. There were no treatment effects on dry matter intake. Gain efficiency and estimated dietary net energy (NE) were greater 8.3% and 5.2%, respectively for HF during the initial 112-d period. Overall (308-d) gain efficiency and estimated dietary NE were similar for both dietary treatments. However, due to differences in tabular dietary NE, the ratio of observed:expected dietary NE tended to be greater (4.1%, p = 0.06) for the HF vs LF diet. There were no treatment effects on carcass characteristics except for a tendency toward a slightly greater (0.5%, p = 0.09) estimated carcass yield. Reducing the non-structural carbohydrate concentration of a conventional steam-flaked corn-based growing finishing diet for Holstein steers can effectively enhance growth performance, particularly during the early

    Montbéliarde (MO) × Holstein (HO) and Viking Red (VR) × HO crossbred cows were compared with pure HO cows in 8 large, high-performance dairy herds. All cows were either 2-breed crossbred or pure HO cows that calved for the first time from December 2010 to April 2014. Best Prediction was used to calculate 305-d milk, fat, and protein production, as well as somatic cell score, and 513 MO × HO, 540 VR × HO, and 978 HO cows were analyzed for production in first lactation. Calving difficulty was scored from 1 (no assistance) to 5 (extreme difficulty). The analysis of calving traits included 493 MO × HO, 504 VR × HO, and 971 HO cows at first calving. Age at first calving was similar for breed groups, and the herds calved both crossbred (23.8 mo) and HO (23.9 mo) cows at young ages. The MO × HO crossbred cows had +3% higher production of 305-d fat plus protein production (actual basis, not mature equivalent) than the HO cows, and the VR × HO were similar to the HO cows for fat plus protein production. Breed groups did not differ for SCS during first lactation. The VR-sired 3-breed crossbred calves (from MO × HO dams) were similar to pure HO calves for calving difficulty; however, MO-sired male calves born to VR × HO dams had a mean score that was +0.5 points higher for calving difficulty than pure HO male calves. The 3-breed crossbred calves from both MO × HO (4%) and VR × HO (5%) first-lactation dams had a much lower stillbirth rate compared with pure HO calves (9%) from first-lactation dams.

    There is national and international concern for increasing obstetric intervention in childbirth and rising caesarean section rates. Repeat caesarean section is a major contributing factor, making primiparous women an important target for strategies to reduce unnecessary intervention and surgeries in childbirth. The aim was to compare outcomes for a cohort of low risk primiparous women who accessed a midwifery continuity model of care with those who received standard public care in the same tertiary hospital. A retrospective comparative cohort study design was implemented drawing on data from two databases held by a tertiary hospital for the period 1 January 2010 to 31 December 2011. Categorical data were analysed using the chi-squared statistic and Fisher's exact test. Continuous data were analysed using Student's t-test. Comparisons are presented using unadjusted and adjusted odds ratios, with 95% confidence intervals (CIs) and p-values with significance set at 0.05. Data for 426 women experiencing continuity of midwifery care and 1220 experiencing standard public care were compared. The study found increased rates of normal vaginal birth (57.7% vs. 48.9% p=0.002) and spontaneous vaginal birth (38% vs. 22.4% p=rates of instrumental birth (23.5% vs. 28.5% p=0.050) and caesarean sections (18.8% vs. 22.5% p=0.115) in the midwifery continuity cohort. There were also fewer interventions in this group. No differences were found in neonatal outcomes. Strategies for reducing caesarean section rates and interventions in childbirth should focus on primiparous women as a priority. This study demonstrates the effectiveness of continuity midwifery models, suggesting that this is an important strategy for improving outcomes in this population.

  18. 1988. aasta suveräänsusdeklaratsioon: silmakirjalikkuse tsiviliseeriv mõju / The Estonian Declaration of Sovereignty: An example of the civilising force of hypocrisy

    Directory of Open Access Journals (Sweden)

    Hent-Raul Kalmo

    2011-01-01

    Full Text Available Sovereignty has been characterised as a form of “organised hypocrisy”, a system governed by a set of rules that are generally recognised as binding and yet continually infringed by the most powerful actors. This idea can be extended to analyse the role of sovereignty within the Soviet Union. The latter was also nominally governed by a constitution which endowed the Union Republics with the right of secession, but there was no realistic possibility of exercising this right. One should not rush to conclude, however, that the letter of the Soviet Constitution of 1977 was entirely without relevance. As Jon Elster has argued, hypocrisy can be a “civilising force” when the need to appear impartial and retain public credibility forces actors to choose a strategy they would not have chosen otherwise. A good example of this kind of argumentative constraint is offered by the dilemma faced by the Soviet leadership after the mid-1980s, as it became reluctant to use military force to suppress independence movements within the Baltic States while, at the same time, promising to give more weight to the Soviet Constitution and respect the “sovereignty” of the Union Republics. In this setting, the ambiguity of the word “sovereignty” could be used by a whole gamut of political movements in order to further their agenda, from local communists eager to expand their autonomy within the Soviet system to those making an explicit bid for the restoration of independence. Significant legal and political changes could be justified as mere conclusions from the constitutionally recognised status of the Union Republics — a strategy which was all the more effective as Moscow struggled to formulate an alternative line of constitutional interpretation that could be used to counter the Baltic claims. This exchange of opinions escalated into a constitutional conflict in November 1988 when the Estonian Supreme Soviet responded to proposed amendments to the Soviet

    The purpose of this comparative study is to describe the differences between Finnish and Estonian students evaluations about their client-centeredness and educational support they received to develop it. Client-centeredness has many positive effects on the quality and effectiveness of care. However, some deficiencies have been identified in the client-centeredness of nursing staff. Research on the subject has been limited, and we lack knowledge of graduating students' competence in client-centeredness and the support of their education to develop it. The sample consisted of 390 undergraduate nursing students, 195 from Finland and 195 from Estonia. The data were collected in 2009 using the structured five-point scale questionnaire. The questionnaire was designed to measure students' client-centeredness and the educational support they received from nursing education. The data were analyzed by the PASW Statistics 18-programme using descriptive statistics, Kolmogorov-Smirnov test and Mann-Whitney U-test. Predominantly, students in both countries evaluated their level of client-centeredness high. The Estonian students generally evaluated their client-centeredness higher compared to the Finnish students. The same applied to support provided by nursing education. The greatest differences were related to education and particularly theoretical teaching. In Estonia, students' client-centeredness manifested itself more in politeness and willingness to serve clients, whereas respecting the clients' values was emphasized in Finland. Students' requisites, referred here as knowledge, skills and abilities to implement client-centered nursing, for client-centeredness had deficiencies, and the support from education was also the weakest regarding these aspects. In future, education on development of nursing activities, acquisition of knowledge and services provided by health care as well as legislation should be enhanced, since these areas proved the most difficult for the students

    Craniofacial duplication abnormity is a rare phenomenon in buiatric practice. This report attends to a male German Holstein calf which could be classified as a diprosopic iniodymus. A fetus exhibiting a doubled face was delivered after fetotomy. To our knowledge, this is the first description of diprosopiasis with two cranial cavities as well as two separate encephala in a calf showing the potential extent of duplication. Throughout this work also the question is answered of whether this malformation in a bovine species arose from one embryo or rather, there is a dizygotic background by genotyping of tissue samples from both parts of the diprosopus. Regarding etiology, not only hereditary dispositions including among others a failed function of the signaling molecule Sonic hedgehog mediating regulation of craniofacial morphogenesis, but also incompletely separated monozygotic twins are discussed.
