The purpose of this thesis is to investigate the possibility to make small, cheap and ultra low power sensor platforms, connected in wireless networks for monitoring of home and industrial environments. The concept is based on ideas from our supervisor, Jerry Lindblom. The developed system consists of a generic platform for different sensors, a receiver and software. A GPRS module from RO Rollytech AB and a database from Gema Industri AB have been modified and used to demonstrate an example of a complete system. To the platform, it is possible to connect any resistive sensor and any sensor that can act as a switch.

The number of weaned piglets per sow and year is a good measurement of sow productivity since it is affected by the number of piglets born alive, the pre weaning mortality (i.e. mortality of live born piglets between birth and weaning) and the number of litters per sow and year. This measure is also closely connected to the number of piglets produced per year, which partly determines the profitability of the piglet producer. During this study, eleven successful piglet-producing herds were visited. Eight of the producers were Swedish and three of the producers were Danish.

Half of Sweden?s 140 000-150 000 sows are culled and replaced by 75 000 gilts annually. Culling of old sows is necessary and allows new breeding material to enter the herd. However, many of the culled sows are young, and have not yet become profitable at the time for culling. Therefore, it is an important question for the pig industry, how to raise gilts to sows with a high and sustainable production level.

Stem rust, Puccinia graminis, has caused enormous yield losses throughout history which have had significant consequences for oat and wheat production. Today in Sweden stem rust is only reported from rye, oats and wild grasses. Stem rust infections in wheat have become unusual due to the general use of resistant wheat varieties and also due to the eradication of barberry, Berberis vulgaris, the alternate host for P. graminis. According to international sources, new races of P.

Subclinical mastitis (SCM) is a well-known problem in the dairy sector, where it causes severe economic losses mainly due to reduced milk production. This is a problem not only in the western world but also in developing countries. Surveys from different developing countries have shown a SCM prevalence of 52.4 ? 88.6 % at cow level and 26.7 ? 63.2 % at quarter-level. To combat mastitis is important to optimize the milk production of the cow.

Aquatic organisms are usually not exposed to single substances but rather to mixtures of toxicants in streams located in agricultural areas. The transport of pesticides used in the agricultural area in Sweden is monitored with continuous environmental supervision every year. During 2002-2008 an average of 10 pesticides were found in each sample and 40% of the samples contained substances with concentrations higher than the Water Quality Standards. Chemical risk management is normally based on single-test evaluations. A problem when assessing mixture toxicities is that the constituents and concentrations of pollutants in the environment vary greatly.

BakgrundIntresset för verksamhetsstyrning har ökat de senaste åren och ständigt har det uppkommit nya verktyg för att förbättra den befintliga styrningen. Business Activity Monitoring (BAM) kom in på marknaden för tre till fyra år sedan för att möta de växande kraven. BAM tillhandahåller enkelt utryckt mätning av ett företags aktiviteter med syfte att förbättra styrningen av verksamhetens operationer samt ge stöd för beslutsfattande. BAM är en relativt ny företeelse inom systemstöd och i Sverige är det endast ett fåtal företag som har implementerat tekniken.ProblemDå det ständigt uppkommer nya system för styrning på markanden kan det ibland vara svårt att förstå vad som skiljer dem åt. Leverantörer av BAM utger sig för att tillhandahålla en lösning till styrningsrelaterade problem, frågan är om företag i verkligheten har dessa problem och vill få dem lösta.SyfteSyftet är att beskriva hur styrningen ser ut i 10 tillverkningsföretag i Sverige, med syfte att identifiera medvetenhet, användning, intresse samt behov av BAM.MetodDå det finns begränsad forskning och teoribildning gällande BAM har uppsatsen en explorativ karaktär.

Samhället är uppbyggt av organisationer som i olika grad kan vara i behov av styrning för att upprätthålla en viss funktion. Studiens syfte är att undersöka hur organisationer inom privat sektor konkret tillämpar styrning och hur arbetet med styrning följs upp. Forskningsfrågor som besvaras är: vad bidrar styrning med till en organisation och dess måluppfyllelse samt på vilket sätt påverkar styrningen hur ledningen använder och arbetar med resultat samt avvikelser? Studien är kvalitativ där datainsamlingen gjorts med semistrukturerade-intervjuer samt genom fenomenografi, det vill säga med en kvalitativ inriktad empirisk forskningsansats. Urvalet av respondenter gjordes inom Västra Götaland där ett 20-tal privata organisationer kontaktades för att erhålla svar om deltagande från potentiella respondenter.

Running water-pathways have played an important roll in Sweden and frequently been manipulated. One profound change was made during the period of logging when streams were cleared from obstacles as big boulders, sharp bends and side-streams. Dams and different constructions gave control of the stream water and the streams became channel-like with a homogen structure. This interference gave problems for many fish populations and resulted in a shortage of feeding habitat, over-wintering habitat, spawning habitat, unnatural flow regimes, sedimentation, unnatural temperature fluctuations. Many of these historical changes of the watersheds are now subjects for restoration, ie., bring back the streams to what we believed it was before the change. However, what once existed in terms of complexity is now gone and difficult toreplace.

This study examines whether or not there are inherit flaws in Swedish legislation concerning psychiatric institutional care, or in the application of the act, which might lead to the failure of rule of law for the private citizen. Law (1991:1128) concerning psychiatric institutional care in certain instances (LPIC) aims to establish rules which will ensure rule of law for the mentally ill in case of psychiatric institutional care. Despite this, there are legal cases which indicate that these rules, and their implications, are not always considered at the psychiatric wards.The questions at issues which this study aims to answer are thus: Are there any deficiencies concerning rule of law in LPIC 2?3 §§, 4?6 §§, 7?10 §§,15?25 §§ and 32?33 §§ ? This section focuses on LPIC and its design. Whether or not the act adheres to rule of law is examined through a definition which has evolved through discussions of concept based in Peczeniks definition of rule of law.

The purpose of this study is to dig deeper into the perceptions regarding diversity - and the ambition to achieve increased such - among those who have participated in the Swedish Public Service diversity coach education. Furthermore, the aim is also to problematize, and increase the awareness of, different outlooks on diversity and its practical usage. All in all, ten so called ?Zebra coaches? have been interviewed for this study. The empirical material has been analysed through a theoretical framework that problematizes the constructs of inequality, based on gender, ethnicity, race, class, etc., on different levels.

Psykisk hälsa/ohälsa är ett svårdefinierat begrepp som sätter fingret på ett av de största folkhälsoproblemen i vårt land, där depression är en av de vanligaste diagnoserna. Manualerna DSM-IV TR och ICD-10 används inom stora delar av sjukvården, världen över, i syfte att ge kunskap om lämpligast behandling till patienter med psykiska besvär. Denna studie syftar till att, genom en kvalitativ analys, undersöka vilka grunder som finns bakom de vanligast använda diagnosmanualerna och vilka kriterier som krävs för att uppfylla två vanligt förekommande diagnoser, PTSD och svår depression. Vidare syftar studier till att belysa eventuella likheter och olikheter mellan dessa diagnoser och vad det kan föra med sig. Såväl psykologisk forskning som klinisk praktik utgår idag mestadels från psykiatriska diagnoser, vilket kan ha såväl fördelar som nackdelar, men samtidigt diskuteras huruvida man istället ska lägga fokus på en annan mer underliggande nivå, nämligen processerna som sträcker sig över diagnosernas gränser.

Idag styr och planerar de flesta organisationer i någon form, det gäller både den privata sektorn som den offentliga sektorn. Det finns olika sätt och modeller man kan använda för att styra en verksamhet t.ex. genom balanserad styrkort. Styrning startas oftast från centrala direktiv som t ex en affärs/verksamhetsplan, budget, prognos, resultatmål, avkastnings mål etc. Styrningen kan baseras på mer eller mindre komplexa styrmodeller och hanteras rent praktiskt via någon form av systemstöd men ibland endast med hjälp av Word- och Exceldokument.
