This paper describes a method for wireless energy transfer via near-field electromagnetic inductionthat is inexpensive, simple and can be applied to almost any type of system, regardless of size andenergy demands.The method uses a primary unit consisting of an oscillator, amplifier and inductive coil thattransfers energy to a secondary unit consisting of a coil, rectifier and voltage regulator. Two typesof oscillators and several amplifier designs were realized and evaluated together with a multitudeof flat coils of both monofilar and bifilar type.The results show that it is important to use an oscillator whose frequency is dependent on theinductance of the connected transmission coil, such as the Colpitts oscillator. This is preferable toan oscillator with a preset frequency, such as a Schmitt-trigger oscillator..

Som ett kommunikationsverktyg och en ledarskapsaspekt tjänar feedback många syften i enorganisation, och är därför ett ständigt aktuellt och relevant ämne. Somliga ledarstilar passarbättre än andra i olika organisationer, då organisationskulturen har en stor påverkan på hurledarskapet mottages. På grund av detta påverkas även relationen mellan ledare och medarbetareoch hur tvåvägskommunikationen, feedbacken, sker mellan parterna. I denna uppsats undersökssamspelet mellan feedback och organisationskultur & ledarskap i syfte att utveckla feedbackeninom organisationer. Hur feedback sker, problem i samband med feedback och förutsättningarnaför feedback har varit viktiga aspekter som har undersökts i denna studie.

Tail-biting in pigs is an animal welfare issue and in Sweden during 2002 the producers lost tree million Swedish crowns because of tail biting. This economic loss depends on the pigs which are discarded at slaughter because of tail biting. Tail biting can be separated into two stages, "pre-injury" and "injury". The aim of this study is to investigate if tail biting depends on environment or genetic background.A lot of research on the environments effects on the behaviour of pigs but not so much on the genetic effects has been performed. The frequency of tail biting in pig farms influence among others of environment enrichment, ventilation, gender and breed of the pig.

Enligt våra erfarenheter från vår verksamhetsförlagda tid påverkas elevers inställning till matematik av den feedback läraren ger dem. Syftet med denna rapport är därför att undersöka och analysera diskurser innehållande feedback från lektioner i gymnasieskolans matematikkurs A. Detta görs genom att observera fyra lektioner utifrån en ljudinspelning och därefter kategorisera 54 utvalda sekvenser. Kategoriseringen görs utifrån fyra olika feedbackdiskurser där den kvalitativa analysen av dem görs utifrån både ett ålders- och ett pojk-/flickperspektiv. Resultatet pekar inte på några tydliga skillnader mellan pojkar och flickor och vi kan inte dra några generella slutsatser om ålderns betydelse i de olika feedbackdiskurserna i vår undersökning.

Cheetahs in the wild are declining due to hunting, lack of prey, exploitation of habitats and loss of cubs to predators. Those are the main reasons to why cheetahs are kept in captivity today for conservation. Many cheetahs kept in captivity are seen pacing ? a behaviour that arise when the animal is prohibited from performing natural behaviours. It is believed to being attributed to a lack of stimulation in the environment where they are being held.

This study is based on a qualitative study with 8 semi-structured interviews. The aim of thestudy was to describe how social workers in the individual- and family section in socialservices in two different municipalities in Sweden reason about reporting obligations and tounderstand what lex Sarah means in the decisions making to report incongruity or not. Weinterviewed social workers that work in the department of individual- and family section, amunicipality worker who works with state governance with all kinds people in the society.We asked the social workers altered questions about how they handle lex Sarah in their work.Three different topics were identified in our study and became the themes: Description,management and conflicting thoughts. Our analysis is based on two different theories, oneabout the choices a person make being in an organization, the other about how a professionalindividual have altered pressures to handle in their everyday work. By doing a semi-structuredstudy of the social workers opinions, we found out that the description of incongruity was notthe focus just in managing lex Sarah.

This thesis has been done in collaboration with Peab Stockholm Building 3, which is a region within the Peab Sverige AB. The report is based on a survey and studies of Peab business management systems and production literature. For general information gathering has literature from well-known sources collected in libraries and through the Internet. It shows through the work that Peab has routines for experience feedback in the construction process, but that these procedures work in a small scale and the practical work experience feedback does not work at all. This is also something the construction industry in general also perceived as problematic. The questions in the report are of a wide scale and concerns construction errors cost, how the employees perceive that the company takes advantage of the skills and the mental stress in production line. The goal is to find how Peab Stockholm Building 3 will work on the experience feedback to allow for better productivity. In conclusion, the report author tries to demonstrate what can lead to increased productivity and improved work experience..

 Den ökade globala konkurrensen har lett till en mer osäker arbetsmarknad som kräver allt större flexibilitet hos individen. Osäkerheten på marknaden har lett till en upplevelse av anställningsotrygghet hos individen. Anställningsotrygghet antas ha konsekvenser för både individ och organisation. Syftet med föreliggande studie är att undersöka om ledarskap kan reducera anställningsotrygghetens konsekvenser (arbetstillfredsställelse, organisatoriskt engagemang, intention att lämna organisationen och tillit till organisationen). Tre olika aspekter av ledarskap står i fokus: kommunikation med chefen, feedback från chefen och stöd från chefen.

Studien undersöker relationen mellan kommunikation och organisationsförändring. Studien tar plats på en klinik vid ett svenskt sjukhus. Två frågor ställs, vilka är: Hur har kommunikation använts i förändringsprocessen? Och, vad har kommunikationen inneburit för de berörda och deras syn på förändringarna? Resultatet visar att kommunikation oftast ses som feedback för att förbättra förändringarna och för att skapa delaktighet. Huruvida kommunikation faktiskt ses som feedback och delaktigheten är äkta, ifrågasätts också.

ObjectiveThe objective of this study was to investigate the clinical application to use ASSR in anesthetized childrenDesignOne main ambition of the investigation was to compare hearing threshold using ABR with estimated hearing threshold using ASSR. Another aim was to examine if the duration of an ASSR measurement could be reduced by only using the frequencies 1, 2 and 4 kHz and exclude the frequency 0.5 kHz. This is a retrospective study using electrophysiological measurement from a database.ResultResults showed a high correlation between hearing threshold using ABR and estimated thresholds using ASSR, with the frequency 0.5 kHz showing a slightly lower correlation. Result also showed that the test duration was increased when using all test frequencies in ASSR-measurement compared to when 0.5kHz was excluded. ConclusionThe study showed a high correlation when comparing hearing threshold using ABR and ASSR.

Breast cancer is the most common form of cancer affecting women. The treatment of breast cancer may lead to forcing the woman to remove her breast. The breast is a symbol of femininity and sexuality for many women. The purpose of this literature-based study is to describe women's experiences of altered body image and sexuality after mastectomy. This may provide a better understanding of the nurse in responding to these breast cancer patients.

The aim for this study where to investigate the frequency of cutting cracks in saw timber harvested in the storm-damaged forests in regions where the storms Hilde and Ivar hit. The idea for this work came from one of the region?s biggest actors, SCA Skog and Jämtlands district. The purpose where to find out how big proportion of the saw timber that contains cutting cracks, their financial cost in lost wood value and also give advice and suggestions on how to work against the frequency of cutting cracks. For the field-study some guidelines where used to make sure that the samples were taken under the same conditions, they were: ? The field-study must be performed under harvesting of storm-felled forest, which are horizontal/inclined trunks. ? The averaged sized tree will make it possible to harvest saw timber. ? The trunks can?t be root cut. A methodology called in Swedish ?Trissmetoden? was used because it is the most frequent used methodology in earlier performed studies and the only one that can be used I field. Under the field-study data were collected from 570 saw timber logs, 30 logs from each one of the tested harvesters.

Uppsatsens syfte är att belysa hur vision, målstyrning och feedback upplevs av omsorgspersonal då de dagligen inte har tillgång till en fysiskt närvarande chef. För att uppnå vårt syfte har vi valt att genomföra en kvalitativ studie,i en mellanstor kommun som aktivt arbetar med vision och målstyrning sedan ett antal år tillbaka. Det empiriska materialet utgörs av fyra stycken intervjuer med omsorgspersonal utifrån semistrukturerade frågor. Våra frågeställningar är följande: Hur upplever omsorgspersonalen på självstyrande enheter implementering och förankring av organisationens vision i sitt dagliga arbete?  Hur upplever omsorgspersonalen på självstyrande enheter att målstyrning fungerar? Hur upplever omsorgspersonalen på självstyrande enheter möjligheten till feedback med en fysiskt frånvarande chef?   Vad anser omsorgspersonalen på självstyrande enheter om chefens närvaro/frånvaro? För att tolka och analysera vår empiri, har ett hermeneutiskt förhållningssätt och en abduktiv ansats använts.
