Analyses of udder health in Valle del Belice dairy sheep using SCC
2005
Intramammary infections (IMI) are a complex of inflammatory diseases of the mammary gland. Mastitis is one of the most frequent IMI affecting small dairy ruminants. Direct selection against clinical mastitis is difficult because mastitis in not widely recorded; therefore, somatic cell count (SCC) is promoted as selection criterion for mastitis resistance. A dataset containing 2,457 first- lactation Valle del Belice ewes from 14 flocks recorded from 1998 to 2003 was analysed. In total 116 sires with at least four daughters with a record were included in the pedigree file. Test-day IMI events were coded as a binary trait using a SCC cut-off value of 750,000 cells/ml. Analyses of risk factors …
Associations of near work time, watching TV, outdoors time, and parents' myopia with myopia among school children based on 38-year-old historical dat…
2021
Purpose To study the prevalence and risk factors of myopia with data from a questionnaire study conducted in 1983 among Finnish school children. Methods School children (n = 4 961) from the 1st, 5th and 8th grades of school (7-, 11- and 15-year-olds) in Central Finland were screened for vision followed by a questionnaire, which was returned by 4 352 (87.7%) participants. Myopia was categorized based on the questionnaire. Items concerned daily time spent on near work and outdoor activities, excluding time spent at school, watching TV and parental myopia and the associations of myopia with these factors were studied. Results The prevalence of myopia was 3%, 15% and 27% among the 7-, 11- and 1…
IMI Prevention of Myopia and Its Progression
2021
The prevalence of myopia has markedly increased in East and Southeast Asia, and pathologic consequences of myopia, including myopic maculopathy and high myopia-associated optic neuropathy, are now some of the most common causes of irreversible blindness. Hence, strategies are warranted to reduce the prevalence of myopia and the progression to high myopia because this is the main modifiable risk factor for pathologic myopia. On the basis of published population-based and interventional studies, an important strategy to reduce the development of myopia is encouraging schoolchildren to spend more time outdoors. As compared with other measures, spending more time outdoors is the safest strategy…
Toimijuutta toisella kielellä : kansainvälisten sairaanhoitajaopiskelijoiden ammatillinen suomen kielen taito ja sen kehittyminen työharjoitteluissa
2017
This dissertation focuses on the development of the agency and professional Finnish language skills of international nursing students studying in an English-medium degree program in Finland. The study draws on sociocognitive and ecological perspectives to examine the social nature of language and its use. This ethnographic theoretical-methodological orientation helps to analyze both subjectively experienced and collectively emergent factors. This longitudinal, multidisciplinary, and multimethodological study examines how the professional language skills and agency of international nursing students develop during their practical training. More specifically, the focus is on the situated and e…

Capturing situational interest in the past : the salience of children’s experiences in open-air museums
2019
Open-air museums are immersive learning environments disseminating ideas about the lifestyle and material culture of pre-modern times. Considering their significance and prevalence in Northern and Eastern Europe, little is known about how contemporary children perceive these cultural heritage spaces. This study scrutinizes how primary school pupils from Sweden and Belarus encountered visits to Skansen (Sweden) and the Belarusian State Museum of Folk Architecture and Rural Lifestyle (Belarus) and expressed experiences about their visits in drawings and in follow-up interpretations. To record the patterns in children’s experiences, a mixed method was employed, including participant observatio…
Ultra-High Energy Neutrinos at the Pierre Auger Observatory
2013
The observation of ultrahigh energy neutrinos (UHE nu s) has become a priority in experimental astroparticle physics. UHE nu s can be detected with a variety of techniques. In particular, neutrinos can interact in the atmosphere (downward-going nu) or in the Earth crust (Earth-skimming nu), producing air showers that can be observed with arrays of detectors at the ground. With the surface detector array of the Pierre Auger Observatory we can detect these types of cascades. The distinguishing signature for neutrino events is the presence of very inclined showers produced close to the ground (i.e., after having traversed a large amount of atmosphere). In this work we review the procedure and …
Nanofilm Low Cost Oxygen Sensors
2009
Abstract The resitivity change of ultra thin metals under air exposure is used for vacuum or inert gas packaging control. In order to reach low cost, single use applications, few nm thin Aluminum layers were deposited on PET substrates and combined with wireless electronic readout circuitry. The sensor respose is characterized by resistance changes and explained in terms of multiphase diffusion mechanisms which are very sensitive to technological parameters.
