In theory, the management control of maintenance functions is described as problematic due to the nature of the work performed in the unit. The purpose of this thesis is to examine these predicted problems in practice. Further,the thesis aims at identifying how these control problems may affect the relationships between the maintenance department and its internal customers. A case study has been conducted in one of Sweden?s largest industrial companies to investigate the said control problems in practice.

Weaning is one of the most critical events in the piglet production with problems such as growth check and post-weaning diarrhea as a result. The lighter the piglets are when the growth check occurs, the harder they have to get back to normal growth rate. Creep feeding of piglets is used to reduce the problems by increasing the weaning weight and adapting the digestive tract to a starter diet. Hodge (1974) showed that the sow?s milk can not provide enough nutrients for maximal growth rate.

Sedan outsourcing blev vanligare på den svenska marknaden har det även blivit vanligt att i förvaltning upphandla sin drift i konkurrens. I ett mycket tidigt skede uppmärksammandes en problematik med samarbetet mellan beställare och driftentreprenör som innebar att fakturahanteringen mellan parterna var omfattande och tidkrävande. För att bland annat minska administrationen upprättades en självriskmodell som många beställare idag tillämpar i kontrakten, vilken innebär att driftentreprenören ersätter felavhjälpande underhållsåtgärdskostnader upp till ett visst gränsbelopp. Syftet med fallstudien är att undersöka modellens uppbyggnad och tillämpning samtatt analysera vad beställare och entreprenör anser om självriskmodellen.Studien bygger främst på primär insamlad data genom ett antal intervjuer med främst en beställare, Locum samt en sekundär datainsamling i form av en enkätundersökning besvarad av verksamma entreprenörer inom branschen.För att bibehålla det offentliga fastighetsbeståndet och för att se till brukarens bästa måste en förståelse finnas mellan beställare och entreprenör. Den lösningen som idag finns för att upprätthålla kvalité och service i en funktionsupphandling är att använda självriskmodellen. För beställaren fungerar modellen som ett incitament att funktionskraven uppnås och för att minska fakturahanteringen.

The anatomy and physiology of reptiles and mammals are in many ways different, and will therefore possibly complicate anesthetic administration. Lizards are ectothermic and one should keep in mind that a decrease in the lizard?s environmental temperature may result in reductions in anesthetic metabolism. Respiratory depression is a profound problem because lizards lack a diaphragm, making inhalation and expiration completely active processes. This, in combination with cardiac shunting and breath holding makes the effects of anesthesia unpredictable.

Wheat yield depends on the number of ears per m2, the number of kernels per ear and the kernel weight. By knowing the ability of different cultivars to compensate for the different yield components and knowing which yield component that is the most important for the final yield, the farmer can match the cultivar and management to the location. The objective of the study was to investigate how the yield components of winter wheat vary depending on genotype, environment, sowing density and date of sowing.Seven varieties were grown in four locations in Sweden with three different sowing densities and with an early and a late sowing date. On each experimental site, the surviving plants after winter were counted, as well as the number of shoots at early and late spring and the number of ears. Ten ears from each site were cut at three different occasions, starting from the time of blooming, with 200 day degrees between each cut.

I denna rapport har det utförts två fallstudier från två olika vindkraftsanläggningar och med hjälp av en utarbetad modell har livscykelkostnaderna jämförts för de två fallstudierna.Resultatet visade att livscykelkostnaden per producerad kWh sjunker allteftersom den installerade effekten blir högre.Kostnadsmodellen som utarbetats och tillämpats för resultaten har visat sig ha hög verifierbarhet då resultaten har varit jämförbara med litterära studier..

Ternary codes for unequal error protection is a part of a communication system where different parts of the information to be transmitted can receive different amount of error protection. There are a lot of applications where the channel conditions fluctuate so that reliable or acceptable communication can not be guaranteed. Regardless whether the fluctuations of the channel are intentional or not the idea is to let the coderate decrease so that the error correcting capability can increase for the part of the information to be more protected. By using the support, the nonzero positions of the ternary code, a new binary code can be extracted with properties different from the ternary code in the sense of cardinality and minimum Hamming distance. When the channel conditions are good the receiver decodes the message using ternary decisions and receives all information included in the codeword.

This thesis is a part of the project "Sustainable harvesting and storage of sugar beets, more sugar to practice". The work has included a large part of practical experimental work with weight measurement, graduation and storage planning. The aim of the project is to be able to see whether the cultivars react differently in different storage conditions. The project has included storage under controlled conditions to give as accurate results as possible. To be able to mimic the farmers own preconditions the samples was harvested with a conventional Holmer.This project has two parts, one concerning the nature, time and temperature on storage where a number of different cultivars where investigated during three different recording times, two different temperatures and controlled in a controlled environment.

The aim with the thesis is to get deeper knowledge in one of the subjects botany, livestock technology or economy. I have chosen to get deeper knowledge in how to store potatoes. How are you going to act to keep the quality on the potato during the storage, with a minimum of weight lost? My aim with this thesis is to get a view over how the potato act in storage space. The storage environment is very important in the storage space.

Today the individual ventilated cage system (IVC-system) is a commonly used housing system for mice in research facilities. IVC systems have HEPA- filters and are designed to control both supply and exhausted air at cage level, as well as temperature and relative humidity in the cages. This creates an optimal environment for the mouse and at the same time a protection against the risk of cross-infection between cages and the outside environment. The aim of this study was to evaluate the health and welfare of breeding females and pups of two different strains of laboratory mice (NMRI nude mice and C57BL/6N) in three different kinds of IVC-systems; Arrowmight, Allentown and Tecniplast. The NMRI nude (Nu) females gave birth to 18 litters in Allentown, 16 litters in Arrowmight and 15 litters in Tecniplast.

Costs of maintenance on agriculture machines is something that many farmers has a low knowledge of, it can depend on low interest or that the farmer don?t have enough time. To make it easier for the farmers they can use many computer programs which are available on the market. In this program they can calculate their costs of maintaince on their agriculture machines, for example STANK and JTI machine calculation program. Most of this program is using Svensson (1987) costs model whish was made in Sweden in the middle of 80 decade in a large study.

The objective with this essay is to establish the benefits of inserting media as an obligatory topic in the upper secondary school. In order to succeed with this I will not only type this essay I will also produce a medial production in the form of a film.  I have interviewed two senior masters on Södertörns College where I have reviewed different questions that relate to the matter's weight in school values and the society. In the study I will also reflect over existing research within the area and to link these to the issue and those interviewed opinions. In the film I also present statistics within the communication technology's increase and an explanation how one obligatory topic becomes an obligatory topic..

Handling of animals during anaesthesia is an important field in the profession as a veterinary nurse and in which intubation is an essential part. Hence, adequate knowledge is necessary for the welfare of the animal. The objective of this literature study was to make it useful and trustworthy for veterinary nurses. It is intended to describe and summarize existing scientificity with its benefits and disadvantages within the different areas of intubation techniques and alternative methods of inhalation anaesthetic supplementation for general anaesthesia in rabbits. Endotracheal intubation in rabbits can be complicated and technically demanding due to the anatomy of the oropharynx including the narrowness of this structure, a relatively large tongue, large incisors and a limited mobility of the temperomandibular joint. The obstructed visualization of larynx and the rabbit?s tendency to develop laryngospasm contributes to the difficulty of intubation. Rabbits are susceptible to tracheal injury and multiple intubation attempts can cause tracheal lesions due to repeated damage to the tracheal mucous membrane, although damage can occur after a single intubation attempt as well. An ETT (endotracheal tube) with or without a cuff can be used during orotracheal intubation in rabbits.

The aim of this report is to analyse the use of the capacity at the CNC (computer numerical control) cutters and show how the level of set up time for these cutters at Stålöv AB. This assignment is concrete whereas there are no subjective questions to this matter and there are only cold figures presented.Production economy is getting more important as the competition hardens and there are several different ways to increase productivity and efficiency in a company. In order to increase productivity and efficiency work studies are used to, through an analysis, find developments in methods that result in improved work methods and to establish the time that are used. Increased production of different parts and customer driven production in combination with increased demands on rationalisation of capital have led to an enlarged interest for shorter set up times in the production.To point out the use of capacity and the set up time of the cutters at Stålöv AB we used frequency studies. Frequency studies are work measure methods based on random observations on predetermined events to calculate the relative occurrence of these events.

During 2006 SNVDB (the national road data base for forestry) is being introduced to Holmen Skog. This data base contains all information about Holmen Skogs road systems. The information will then be used in different kinds of optimisation models which only produce correct and reliable results if the input data are of the adequate quality. Today there are reasons to believe that road data is of various qualities. The forest roads are often in a bad condition and have to be improved before a planned harvest. The cost of maintenance and construction of new roads is a large part of the total harvesting cost.
