Can increased activity recorded with help of activity monitoring sensor indicate an upcoming calving?

The purpose of this study was to find out if motion movements, e.g. number of lying bouts and lying time with a registered activity monitoring sensor can detect an impending calving and thereby be used as a measure and an indicator for an upcoming calving. For this, automatically step sensors were used and were attached to one of the cows? hind leg. The sensor registered the individual step and movement activity of the cow.

En trivsam inskolning : En intervjustudie om interaktion mellan pedagoger och föräldrar

The purpose of this study is to create an understanding of how parents and preschool teachers experience induction at preschool. The induction creates collaboration between preschool teachers and parents where the interaction and socio-cultural factors have been key theories for the work task.The method used has been of qualitative nature where interviews were made with parents and preschool teachers. In these interviews, they shared their insights of how they experienced the interaction and communication during induction. I asked the parents what they felt was good communication and interaction during the induction. The same question was given to preschool teachers to respond to and also if there was something that worked less good during induction.The results show that parents and preschool teachers feel that induction works well satisfactory and that it is important that the interaction work well between both parts.

The hypothalamic-pituitary-adrenal axis and perinatal treatment of premature foals

The danger and vulnerability associated with a preterm birth seem to be closely correlated with a dysfunction of the fetal hypothalamic-pituitary-adrenal (HPA) axis, whose maturation in the foal is without a doubt as delicate as it is important. Not only is this endocrine cascade vital for the foal in order to cope with neonatal stress, it also appears to be fundamental for the final fetal intrauterine maturation, as well as for the onset of foaling. Equine gestation exhibits some rather unique features, indicating a somewhat different significance of the endocrine changes associated with HPA maturation, compared to many other species. This hormonal cascade is rapid and confined to a narrow time during late gestation in the horse, and the risk of the foal completely missing it therefore becomes prominent. Induced parturition in the mare may be operated through uterotonic agents, which occasionally bring about premature foals. Desirable seems the ability to initiate equine labour while simultaneously enhancing fetal HPA maturation, as in humans and ruminants through perinatal glucocorticoid administration. However, similar treatment in the horse has resulted in various, sometimes fatal, outcomes. In the light of the distinctive features of equine gestation, difficulties are encountered following such administration of glucocorticoids and ACTH.

IgG mediated suppression of immunological memory

Apart from recognizing and neutralizing threats, antibodies also have the ability to regulate immune responses against their specific antigen. IgG administered together with erythrocytes is well known to induce >99% suppression. This has been used to prevent haemolytic disease in new-borns since the 1960's, but the mechanism behind it is still not completely understood. The effect on the primary response is well established, but its influence on induction of immunological memory is still heavily debated. In this study adoptive cell transfer of splenocytes to irradiated mice was used to survey the effect IgG has on induction of immunological memory without disturbance from the primary IgG response.

Statusbedömning av asynkronmotorer

Induction motors, often referred to as the workhorse of the industry, play an important role in production today. Therefore, it's important to diagnose any faulty induction motor prior to failure to avoid costly and time consuming production stops.This thesis compares methods for diagnosing induction motors in operation, MCSA, Park's vector approach and the standard method used by Swedish industries today. By simulating broken rotor bars and short-circuit in one of the windings, each method is tested and the results are compared using matlab.The results need further verification due to uncertainties of the condition of the test motor, even though the experiment gives a hint of the different advantages of each method. A combination of the methods should be able to tell if the motor needs further examination..

Hur påverkar byggnadsmaterial av stål en induktiv hörslingas fältstyrka samt frekvensgång?

This research analyzed differences in measurements of magnetic field strength and frequency response in five audio induction loops installed in rooms of wooden construction materials and five audio inductive loops installed in rooms of steel reinforced concrete constructions. The inductive loops were installed at floor level and the measurements were made at the listening height of 1.2m. Measurements of background noise, field strength and frequency response were made at fifteen different measurement points across the room. The research measurements showed that there are differences in field strength and frequency response between these two conditions, whether the audio induction loop is installed in a wooden construction or the audio induction loop is installed in a reinforced concrete construction. The results had a significance level of p=0,05..

Comparison between anesthesia with sufentanil-midazolam and sevoflurane in medetomidine premedicated rabbits undergoing ovariohysterectomy

Rabbits carry a high risk of anesthesia related death. This study was part of a project to develop a form of total intravenous anesthesia (TIVA) with minimal effects on cardiac, respiratory and metabolic parameters. In the study, TIVA with sufentanil and midazolam (group TIVA, n=9) was compared with inhalation anesthesia with sevoflurane (group SEVO, n=9) in female rabbits undergoing surgery (ovariehysterectomi). All rabbits were pre-medicated with medetomidin and carprofen before anesthesia induction. Anesthesia was induced with TIVA (2.3 ?g/ ml sufentanil, 0.45 mg/ ml midazolam) at a rate of 4 ml/ kg/ h and the mean induction dose was 0.4 ?g/ kg of sufentanil and 0.1mg/ kg of midazolam.

Inverkan av stora mängder halm som underlag i grisningsboxen på den nyfödda smågrisens temperaturreglering :

The aim of the present study was to evaluate the effects of large amounts of straw in the farrowing pen on thermal regulation of the newborn piglet in different weight classes. 20 sows were given 15 kg of straw in the farrowing pen 2 days prior to until 7 days after parturition. A control group of 18 sows had no straw in the pen. 6 litters from each treatment were observed. Measurements of piglet body temperature were made at 0h, 2h, 4h, 8h and 24h after parturition. At ?8h? the body temperature of the piglets in the Straw group were significantly higher (P=0,0149) than the piglets in the Control group.

Tänk inte han och hon, tänk individen : En kvalitativ studie om fem förskolepedagogers föreställningar om föräldrakontakt ur ett genusperspektiv

In Sweden today, more women are still going on parental leave than men. The number of men and women going on parental leave is more equalized than ever before. At the same time the inequalities are still big and more women than men choose to work part time up till the child is eight years old.The aim of the study is through a gender perspective, to investigate the preschool teacher?s thoughts about the daily meetings with parents and the contact during induction. The study is based on the theoretical concepts: gender, norms and gender equality as well as three questions.

Student blir lärare : En kvalitativ undersökning om nyexaminerade lärarstudenters erfarenhet av att komma ut i arbetslivet

This paper aims to examine how the beginning of newly examined teacher?s professional life might look like and also highlight the obstacles that might occur during the induction, the time during which the student becomes the teacher. The paper also discusses what support that is available for newly examined teachers in schools concerning the possibility to have a mentor and a period of introduction.A qualitative method was used for this study and interviews were made with new teachers who shared their experiences from the beginning of their careers. The results from the interviews were also discussed from the points of view of the study?s theories concerning different leadership styles.Two handbooks for new teachers, aiming to support them in their new professional role were compared.

Magnesium chloride in dry cow silage to prevent hypocalcaemia

Milk fever, or parturient paresis, is the second most common disease in Swedish dairy cows. The disorder is associated with the onset of lactation when some cows are unable to meet the metabolic demands of calcium to support milk production and therefore develop a state of hypocalcaemia. Clinical hypocalcaemia (milk fever) may lead to coma and death in severe cases but subclinical hypocalcaemia has also been shown to have negative effects on e.g. feed intake and production and to increase the susceptibility of the cow to develop secondary diseases. The nutritional strategy applied precalving is of great importance in preventing milk fever and e.g.

Grupphandledning - ett stöd för nya lärares yrkesintroduktion? : En fallstudie om induction och ett introduktionsprogram för en grupp nyutexaminerade, nyanställda lärare

Syftet med denna uppsats är att fokusera de queera ögonblicken i J.R.R. Tolkiens trilogi The Lord of the Rings för att visa att det queera finns i kulturen på samma sätt som det icke-queera. När är de två hobbitarna Frodos och Sams relation queer? Vad gör den queer? Hur kan vi förstå denna queerhet i termer av homosocialitet och homoerotik? Uppsatsen är inspirerad av Tiina Rosenbergs queera läsningar, jag använder mig dessutom av Adrienne Richs teori om "lesbisk kontinuitet" och Sedgwicks resonemang om manligt homosocialt begär. Jag har kommit fram till att Frodos och Sams relation rör sig mellan mer och mindre queerhet.

Översvämningsanalys med hänsyn till Länsstyrelsens handbok : Planering för stigande vatten i Kristinehamns kommun

This thesis has been adjusted because some parts are classified, some sentences might have been changed. Electric bikes are a convenient mode of transport, a good choice when long distances or tough slopes can be an obstacle.The goal of the project was to create a prototype on a locking mechanism with an inductive charger for electric bikes.The idea behind the project was to develop a user-friendly locking mechanism, where the bikes would be charged inductively when they were locked. To implement the project facts about induction, battery charging and locking devices was needed to be acquired. Circuits for induction charging were created and a lock device was constructed. A microprocessor was used to control the entire system.A prototype was designed with a locking device and an inductive charger fixed in a bike rack.The entire project became very wide which resulted in that not all of the parts of the project could be completed.

Anestesisjuksköterskans erfarenheter av att utföra Rapid Sequence Induction (RSI) utifrån aktuell evidens

Rapid Sequence Induction (RSI) är en induktionsstrategi   som används när det föreligger risk för aspiration. Metoden syftar till att   tiden från anestesiinduktion till säkrad luftväg blir så kort som möjlig.   Snabbverkande läkemedel ges i följd, patienten har höjd huvudända och   ventileras inte innan luftvägen är säkrad pga. risken för aspiration.   Krikoidtryck kan ingå i RSI och är en metod som kan minimera risken för   aspiration.

Modellbygge och regulatordesign av tröghetsmomentsimulator tillreferenssystem för stridsvagn 122

This master thesis holds a modelling in Simulink for a physical model of a main battletank tower, a three-phase induction motor and some mechanics. The aim of this work is to connect an earlier project at AerotechTelub, named StabSim to another called Eldris. In StabSim it has been made a Simulink model of the align and stabilisation system in a main battle tank 122 and in Eldris it has been build a physical model of a main battle tank tower. In this thesis the models that differs between Eldris and a real tower is changed in StabSim, and the parts that only exist in Eldris is added, for example a torque generating system which purpose is to make the model to behave like a real tower in control application, although it only has half the inertia as a real tower. The thesis even includes proposing a calculation of the torque that the torque generating system will actuate at the model..
