Voltage sag indices are a way of quantifying the performance of the power supply, as far as voltage sags are concerned. Indices can be defined for individual events, for individual sites, and for a whole system. A standard method for single-event methods is part of IEC standard 61000-4-30.This thesis emphasizes the importance of voltage sag indices and different methods for calculating three-phase voltage sag characteristics. Three-phase events measured in a medium network voltage over period of one month were analyzed, results examined and statistically evaluated. An algorithm for calculating voltage sag characteristics and indices was created in Matlab.

There is a lot of research made on second language (L2) learning (Jesney, 2004). However the relationship between foreign accent, intelligibility and acoustics within pronunciation tutoring is quite an unresearched area (Thorén, 2008). The aim of the study was to analyze how a course in Swedish pronunciation affected foreign accent, intelligibility and acoustics among L2-learners of Swedish. A total of 41 people participated in the study: 16 L2-learners, 4 native Swedish speakers consisting a control group and 21 perceptual assessors with Swedish as native language. The L2-learners foreign accent and intelligibility were rated by the listeners before and after a course in Swedish pronunciation on an eight-point Likert-scale.

Syftet med uppsatsen är att försöka förklara vad det är som påverkar tiden som en mamma ammar. För att undersöka vad det är som påverkar tiden som en mamma ammar, har en Zero inflated negative binomial-modell (ZINB-modell) tagits fram. Resultaten visar att det som avgör hur länge en mamma kommer att amma är: Graviditetens längd, mammans ålder, mammans rökvanor under graviditetens sista månader, mammans rökvanor samt mammans nationella ursprung..

Syfte: Att beskriva BVC-sjuksköterskornas erfarenheter av att vägleda mammor med upplevd amningsproblematik för att främja amning. Bakgrund: Bröstmjölk rekommenderas för spädbarn som enda föda upp till sex månaders ålder. Globalt sett syns en nedåtgående trend gällande amning. Det är av stor vikt att skapa en medvetenhet om amningens fördelar för att främja amningsfrekvensen. Studier visar att kvinnor med amningsrelaterade problem som inte fått stöd av vårdpersonal slutade amma i större utsträckning än de som fått amningsvägledning.

Traumatic arthritis is a common cause of lameness in horses. One of different treatment alternatives of arthritis, is intra-articular injection with hyaluronan. As knowledge about pathophysiology of arthritis and function of hyaluronan is increasing, understanding grows about the mechanism of hyaluronan action in joints. Hyaluronan has, in addition to effects on viscosity, anti-inflammatory and analgesic effects. Extensive research and scientific studies have been made on exogenous hyaluronan.

Abstract   Cinematic time is the most complex of all: it is composed of public time (clock), personal time (experienced) and in addition, it can run backwards, be contingent, stored and (re)created. The present study examines some aspects of cinematic time, with special reference to the instant, the moment and the present. The strictly defined instant or moment does not exist. It is a passage between the past and the future and it is impossible to record on film or a photograph. One example is the moment of death, which is an abstraction with zero duration.

BakgrundDiabetes typ 2 är en av de snabbast växande sjukdomarna i både Sverige och resten av världen. Vid diabetes typ 2 utgör egenvård en betydande del av behandlingen och för att klara detta behövs kunskap om sjukdomen. I sjuksköterskeyrket ingår att förse patienter med information och kunskap, bland annat genom patientundervisning. Ett flertal studier beskriver hur information och kunskap uppfattas av patienter och hur det på bästa sätt förmedlas till dem. Däremot saknas ett instrument som mäter patienternas befintliga kunskap om sjukdomen och hur de värderar information.SyfteSyftet med arbetet är att undersöka hur informations- och kunskapsbehovet vid diabetes typ 2 varierar utifrån kön, HbA1c, ålder, utbildning och duration samt identifiera de frågor där informations- och kunskapsbehovet är störst respektive lägst.MetodArbetet grundas på en kvantitativ enkät utformad efter The Toronto Informational Needs Questionnaire-Breast Cancer och är analyserat utifrån data från 86 patienter.  Frågor ur denna enkät har behandlats i dataprogrammet Statistical Package for the Social Sciences och presenteras som deskriptiv statistik.

Chewing behaviour includes both eating and ruminating activity. Chewing behaviour is of great importance for the feed intake as through the action of chewing (i.e. eating and ruminating) animals mechanically process the forages in small particle sizes and prepare the food for digestion. As cattle grow the chewing behaviour changes along with increasing body weight and chewing efficiency is increased. The aim of this thesis was to review the available scientific literature in order to describe chewing behaviour in growing cattle, as well as the factors that affect this behaviour.

Phenylbutazone has been discussed in the world of the equestrian sport several times and different countries have diverse opinions on its use in competitions. The progressive list that permits phenylbutazone with plasma levels up to 8 µg/ml was presented at the FEI General Assembly in November 2009. The list was voted to be accepted, but later several countries realized the consequences and after protests the list was rejected and is going to be discussed again at the FEI General Assembly 2010. In this literature study I have studied the relationship between the concentrations of phenylbutazone in plasma and the effects on lameness. The purpose was to establish whether the limit of 8 µg/ml phenylbutazone in plasma affects the equestrian sport.

AbstractObjectivePatients with Parkinson?s disease often have symptoms of dysphagia. These swallowingproblems have consequences for quality of life as well for the physical wellbeing of thepatients. AimThe aim of this study was to describe and correlate Swallowing Quality of Life (SWAL-QOL)scores, self-assessment of swallowing function using a visual analogue scale and the resultsfrom a fiber endoscopic evaluation of swallowing function in patients who had been selectedfor Deep Brain Stimulation in caudal zona incerta. A secondary aim was to correlate diseaseduration with results from SWAL-QOL and the fiber endoscopic evaluation of swallowingfunction.MethodTen male Parkinson?s patients (age 45-69 yrs, median 61.5 yrs) who were selected for DeepBrain Stimulation completing the Swallowing Quality of life form, as well as rating theirswallowing function using a visual analogue scale and undergoing a fiber endoscopicevaluation of their swallowing function.    ResultsThe median total SWAL-QOL score was 94% while the mean was 91%.

Automatic rumination measuring can be applied as a health indicator in dairy farming but is also highly desirable for research purposes. This study aimed to validate the technical functionality of the product RuminActTM, which employ acoustics to monitor rumination duration. The time budget of high yielding cows was studied and possible differences in rumination time between 13 rations were interpreted. Further the study examined what affects daily rumination and rumination efficiency. The validation was performed with direct observations that were compared to the automatically recorded rumination durations.

ABSTRACTBackground: After general anesthesia the cognitive ability is temporarily impaired. Cognitive recovery is necessary for the patient to be able to assimilate the information that she / he gets postoperatively. It also increases the patient safety. There are few methods to estimate and assess the patient's cognitive recovery before and after anesthesia. The purpose of this study is to test the usefulness of the instrument PQRS and to assess the patients cognitive recovery after anesthesia.

Bakgrund:Delirium innebär en påfrestning för patienten och medför förlängd vårdtid, ökad mortalitet och ökade samhällskostnader. Som intensivvårdssjuksköterska är det därför viktigt att ha kunskap om tillståndet och om preventiva åtgärder. Syfte: Att beskriva vilken kunskap intensivvårdssjuksköterskan behöver och vilka åtgärder som kan utföras för att förebygga utvecklingen av delirium. Metod: Design: Litteraturstudie. En litteratursökning genomfördes i databasen PubMed som resulterade i 20 utvalda, kvalitetsvärderade och evidensgraderade studier.

Alopecia areata (AA) betyder fläckvis håravfall och uppstår vanligen på huvudet men även på kroppen. Det är en harmlös, reversibel, organ-specifik, autoimmun hudsjukdom som drabbar hårfolliklarna. Den autoimmuna reaktionen förmedlas av T-lymfocyter som angriper hårfolliklarna och hämmar hårväxt. Det årliga incidenstalet för både kvinnor och män är 20,2 per 100 000 personer och 1,7 % av befolkningen riskerar att drabbas någon gång under livet. Även om genetiskt anlag och miljöfaktorer, såsom emotionell stress, graviditet och tillfälliga infektioner kan utlösa sjukdomen så är den exakta orsaken fortfarande okänd.
