Genetic variation in dairy cattle claw health traits recorded by claw trimmers

Claw health has been recorded by claw trimmers at trimming in Sweden since 1996, but data was then captured at each AI association. From 2003 data was captured by central scanning and entered directly to the national cow data base at the Swedish Dairy Association (SDA). This reporting was introduced because SDA wanted to be able to use these records to improve dairy cow claw health by breeding. It is desirable with cows that have healthy claws, because poor claw health can contribute to impaired production and fertility. The claw health report begins with some information about herd, claw trimmer, date et cetera and continues with the part where the claw health is recorded. Here the ID of each cow is filled in and on the same row the conditions for dermatitis, heel horn erosion, sole haemorrhage and sole ulcer are recorded as no lesion (blank), slight lesion (/) or severe lesion (X).

Kan supplementering med vitamin E förbättra kognitiv funktion vid Alzheimers sjukdom?

Sahlgrenska Academyat University of GothenburgDepartment of internal medicine and clinical nutritionAbstractTitle: Can supplementation with vitamin E improve cognitive function in Alzheimer?s disease?Author: Malin Andersson and Elin LöfqvistSupervisor: Elisabet RothenbergExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: 2012-04-11Background: Alzheimer?s disease (AD) is the most common form of dementia. As the average life expectancy rises the prevalence increases. The disease leads to gradual deterioration of cognitive functions. A recent Cochrane review describes how several studies demonstrate an increased oxidative damage in the brain in those with AD.

Automatisk bullerdosreglering i hörselskydd

På bullriga arbetsplatser använder personal ofta hörselskydd med inbyggda högtalare för att lyssna på exempelvis musik i underhållningssyfte. Om användaren lyssnar på höga ljudnivåer under långa perioder kan bullerskador uppstå i dennes öron. Enligt lagstiftning måste nivån därför begränsas i förebyggande syfte.Bullernivån är ett genomsnitt av de ljudnivåer användaren exponerats för under en arbetsdag. Användaren måste vila öronen om gränsvärdet för bullernivån nås.Om man utnyttjar att det är ett genomsnitt kan användaren tillåtas lyssna på en hög ljudnivå under en begränsad tid för att sedan sänka den. Det går att bevara både säkerheten och lyssningsupplevelsen om en sänkning införs långsamt.Detta arbete beskriver hur en algoritm till en digital signalprocessor kan konstrueras för att reglera ljudnivån.Målsättningen var att algoritmen skulle skydda användarens hörsel utan att försämra lyssningsupplevelsen, och utan att förbruka mer energi än nödvändigt.I algoritmen ingick en prediktor som predikterar mängden buller användaren riskerar att utsättas för, om denne fortsätter lyssna på samma nivå.Långsamma sänkningar av ljudnivån kan då utföras i tid innan gränsvärdet nås.Det visade sig att algoritmen endast behövde ett fåtal samplingar per sekund för att skatta och reglera ljudnivån tillräckligt precist, vilket reducerade energiförbrukningen.Resultatet visar möjligheten att kombinera målen för säkerhet, lyssningsupplevelse och energieffektivitet i hörselskydd.Algoritmen implementerades inte på ett skarpt system.Den hade enbart tillgång till ljudsignalen användaren ämnade lyssna på i underhållningssyfte..

Dövas och sjuksköterskors erfarenhet och upplevelse av sjukvårdsrådgivning via telefon : Intervjustudie med kvalitativ analys

Sjukvårdsrådgivning via telefon har blivit allt vanligare i västvärlden. Tekniska lösningar har utarbetas som underlättar för de döva att själva kontakta sjukvården via telefon. Sjuksköterskor inom primärvården kommunicerar då med de döva via text- eller bildtelefoni. Studiens syfte var att beskriva döva och sjuksköterskors erfarenheter och upplevelser av sjukvårdsrådgivning via telefon. Sex sjuksköterskor och fem döva intervjuades med öppna frågor.

Fysisk kapacitet hos fysiskt aktiva och inaktiva ungdomar

Background: During the last decade physical activity among Swedish adolescents has decreased. Changes regarding physical fitness can also be seen, for instance the cardio respiratory capacity has decreased mainly among young men while muscular capacity has decreased in both genders. Physical inactivity and impaired physical fitness are both important health related parameters. 18-year olds have fulfilled their physical development and are physically on top of their development, it makes this group interesting to examine. Objective: The aim of this study was to investigate differences between physically active and inactive young men and women, concerning cardio-respiratory fitness, muscular fitness and balance.

Förekomst av leukocyter i råsperma hos semingaltar :

Detection of leukocytes in semen from boars is part of the routine control of semen quality. Leukocytes in semen can cause damage to spermatozoa that leads to impaired fertilization. In the artificial insemination (AI) industry there are standard routines for the quality control of the boars and of the neat semen before use. Since 2001, Quality Genetics has not done the leukocyte examination on semen samples from boars which are used for the production of pigs for slaughter. The purpose of this study was to investigate the occurrence of leukocytes in semen from AI-boars. The questions addressed were whether there are boars that have leukocytes in their semen and how frequently it occurs and, moreover, if there are differences between breeds, or even between individuals whose semen was checked before use in AI-dose production compared to those which were not. The study included a total of 135 AI-boars, of which 67 were Hampshire, 35 Yorkshire and 33 Landrace, all belonging to Quality Genetics AI-station in Hållsta.

Måla med musik, komponera med färg : En retrospektiv studie av den kreativa processen, bland bild, musik och synestesi

The relationship between color and music, and their relation to the human being and our surrounding universe has been subject of studies, theories and experiments since the old ages. From the ancient China and Persia to the present times, philosophers, scientists and artists have tried to explain these connections between color and music and also tried to find answers to this ancient enigma.The invention of the color organ c. 1730, an instrument that was intended to display color in addition to the musical auditive experience, was the first attempt to materialize the practical correlation between notes and color. This correlation has its foundation in the ideas of Isaac Newton, who through his book Optics published only a few years earlier, conformed the beginning of a new art culture: ?Visual music?, in which image and sound are the fundamental elements in the creative process.The ?visual music? concept is not only grounded in the ideas of music and sound, but also in the extraordinary creative capability of certain individuals.

Molekylärgenetisk analys av dilaterad cardiomyopati hos hund :

Canine dilated cardiomyopathy (DCM) is a disease with high morbidity and mortality and with a high prevalence in certain breeds. Predominatly large breeds are affected, such as Great danes, Newfoundlands, Deerhounds and Dobermanns. One exception is Cocker spaniels, where both American and English Cocker spaniels are affected in a quite high frequency. Cardiomyopathy is characterised as a disease that affects the myocardium and gives an impaired heart function. To diagnose DCM following criteria have to be observed: 1. Dilation of the left ventricle. 2. Reduced systolic heart function. 3. Increased sphericity of the left ventricle. To be certain of the diagnosis, alternative reasons for the symptoms such as lung- and heart diseases with other etiologies have to be excluded Two different types of DCM have been found upon histological examination.

Perception of human acoustic communication in the domestic dog (Canis familiaris)

For most dog owners today it is natural to use acoustic stimuli such as talking to communicate with their pets. Words are used both to ask the dogs to perform tricks, as well as to hold ?conversations? with the dog. This literature review looks at how dogs perceive human acoustical communication and how this can influence the behaviour of the dog. This information could be used e.g.

Ger tillägg av ARB till redan pågående behandling med ACE-hämmare hos hjärtsviktspatienter bättre hälso- och kostnadseffekt?

Heart failure is a condition where the heart is incapable of providing adequate blood supply to different organs in the body. The underlying causes of heart failure is some kind of disorder in the heart function, and require careful diagnostics. The basic symptoms that arise from heart failure is difficulty in breathing, that aggravate when lying down, and fatigue. The patients? symptoms and impaired quality of life can be in different stages depending on the severity of the heart failure.

Hur upplevs en främre korsbandsskada som ådragits för mer än 10 år sedan påverka den skadade idag?

Aim: The aim of this study was to investigate how women who have incurred ACL injury for more than 10 years ago, feel that the injury affects them today.Method: A qualitative semi-structured interview survey with five women who 10- 28 years ago incurred the anterior cruciate ligament injuries when playing handball or soccer has been performed. The study has been inspired by a phenomenological concept of science, mainly by life-world concept. Data were analyzed using qualitative content analysis.Main result: Some informants have experienced severe loss of physical ability in both daily living situations and in training, while others did not appreciably felt impacted in daily living and experienced great opportunities for physical activity. Limitations which emerged were restrictions in movement, joint stiffness, pain, swelling, and crepitations that led to the loss of physical ability. One respondent had been diagnosed with advanced osteoarthritis.

Ett litet ord med stora implikationer : En studie om förståelsen kring ordet Gay i allmänt negativ bemärkelse

Many of us have grown up hearing or using words meant as insults or negative adjectives that were in fact names for social groups. Most of them have gone unquestioned in the mainstream consciousness, but the term Gay in the generally negative meaning has in the past years been given attention as offensive and homophobic, with debates emerging in response over whether or not this is true, particularly on the internet. It is the articles and forum threads from these debates that make out the empirical material for a qualitative study as I ask what these people?s thoughts are about this term and how it is perceived.After a qualitative coding and analysis of these texts, and interpretation of the results based on Erving Goffman?s theory of Phantom acceptance and stigma terms, Judith Butler?s theory of performativity, Ferdinand de Sassure?s theory of signifier and signified and how it connects to the community and Baudrillards theory of simulacra, this is the principal conclusion that I have drawn:For some of the people in this debate, the term Gay and its use is about homophobia and heterosexism, though mostly it?s not overt but a subconscious part of the continued dehumanization and stigmatization of homo- and bisexual people. This is a position I callThe socially focused skepticism.

Hur påverkas dvärghamstrar av att vistas i hamsterbollar?

Lately the popularity to keep different species of dwarf hamsters has increased in Sweden. The requirements of the Swedish legislation to keep hamsters as pets are low which could be a reason for the increasing popularity. Hamsters are in nature generally nocturnal and can travel far distances to find food sources during their active part of the day. Their eyesight is poor, but is compensated by their well-developed hearing and olfaction. ?Run about balls? are made of plastic and the hamster is placed inside it where after the ball is placed on the floor and the hamster can then run protected outside the cage.

Upplevda hörselbesvär hos fallskärmshoppare : Identifiering av riskfaktorer för att utveckla en hörselskada

Bakgrund: Studier visar att hörselskador kan uppstå till följd av yttre påfrestningar så som exponering av buller och kraftiga tryckförändringar. Fallskärmshoppare exponeras för bägge dessa faktorer, vilket skulle kunna innebära en ökad risk för att utveckla hörselskador. Trots detta är området mycket sparsamt studerat. En ökad kunskap inom området medför att eventuella behov av preventiva åtgärder kan identifieras.Syfte: Syftet med studien var att undersöka förekomsten av upplevda hörselbesvär hos fallskärmshoppare, samt om det finns något samband mellan upplevda hörselbesvär och antal hopp, användning av öronproppar eller akustiska höjdvarnare.Metod: Studien genomfördes i form av en kvantitativ tvärsnittsstudie. En webbenkät skickades ut till samtliga aktiva fallskärmshoppare med registrerad e-postadress i två fallskärmsklubbar i Mellansverige.
