Osteokondros är en vanlig multifaktoriell sjukdom hos stora och snabbt växande hundraser och kan drabba flera leder så som exempelvis armbågs- och bogleder. En lokal störning i den endokondrala benbildningen i epifysen eller metafysens tillväxtbrosk leder till ojämnheter i brosket, som i sin tur orsakar smärta och hälta. Osteokondros påverkar hundens välfärd såväl som människans användning av hunden. Kunskap om sjukdomsförloppet och faktorer som påverkar sjukdomsutveckling krävs för att förhindra uppkomst av osteokondros. Den här litteraturgenomgången syftar till att klargöra huruvida utfodring påverkar utvecklingen av osteokondros hos hund och i så fall på vilket sätt. Litteraturstudien har avgränsats till betydelsen av överutfodring med energi och protein samt över- eller underutfodring med kalcium och fosfor. För att en normal ledyta ska bildas krävs ett intrikat samspel mellan mekanismerna för skelettillväxt, endokondral benbildning samt benremodulering.

The agriculture is today in a development that leads to bigger and bigger units in the primary production. To be able to follow this development many companies chooses to cooperate in different ways. The most radical change is when farmers fuses with other farmers and merge into to a big collectively owned operation firm. The reason behind this idea is that the firms achieve the big companies advantages by being complement to each other. The purpose of this essay is to make an economic analysis of two crop production companies who works together in an operation firm.

The main objective of this thesis was to develop appropriate strategies and find factors that affect the usability of parameterized designs. This was accomplished by investigate the user-interface and how it is designed to meet the user's information needs. The thesis also embraces the basic theories in terms of investigation, cognitive design principles and human behavior patterns in the interaction with the machine. The approach has led to an explorative investigation in this subject area.The thesis also had the purpose to achieve more efficient ways for development of motor chainsaws at Husqvarna AB's department Global Cutting Equipment. That can be achieved through reduce costs of development per sold unit.

Powder Metal (PM) gears are machine element components which operate under the same principle as conventional gears, but, due to their intrinsic material characteristic need to be designed slightly different, and its manufacturing process offers advantages previously unobtainable by conventional steel gear manufacturing methods. The use of PM in similar applications, such as synchronous hubs, makes them a suitable candidate for production in such material. The current master thesis work focuses on gear design using PM by utilizing finite element method (FEM) to reduce weight and inertia taking into account root bending strength and tooth deflection.First a topological optimization is used to determine feasible candidates for different web designs which have as objective to reduce volume, similar topologies were shown during different loading conditions; and hence, this topology was chosen as a suitable candidate. A shape optimization of the topological candidate was performed having as state variables root bending strength, independent for compressive and tensile side of the tooth loading; and tooth deflection, which in concept can be correlated to static transmission error (TE).Another aspect in this thesis analysed is the possibility to incorporate non-trochoid root geometry, a trochoid root is always present when machining with a hob, into the gear root and hence reduce the stress concentration here. Due to the use of PM, a non-symmetric optimized root can be achieved and hence be optimizing compression and tension.Results showed significantly lower inertia, for example certain results showed 40% reduced when compared to solid gear, with adverse effects as increase in tooth deformation and increase in maximum principal stress.

AssiDomän tillverkar kartong till förpackningsindustrin. Inom detta område är vitheten på kartongytanen viktig parameter. För att höja intrycket av förpackningen samt skapa en skyddande yta lackas ofta förpackningen med UV-lack efter tryck. Efter lackning kan då otryckta lackade ytor uppfattas som mindre vita. För att ta reda på om bestrykningssammansättningen har betydelse har ett fem olika bestrykningar blandats.

Denna litteraturstudie behandlar förgiftningar hos hund med begränsning till förgiftning orsakat av etylenglykol och råttgift. Vilket av dessa ämnen som är farligast och hur stor risken är att en hund får i sig dem är två frågor som kommer att undersökas. Det kommer att tas reda på mer om hur det ligger till med etylenglykolets påstått söta smak. Syftet med studien är även att utreda om allmänhetens medvetenhet behöver ökas om vanliga potentiellt farliga ämnen för våra husdjur. Att hundar utsätts för förgiftningar är inte ovanligt och antalet försäkringsfall där hundar blivit förgiftade har ökat mellan 2010 och 2014. Om en hund utsätts för ett giftigt ämne är det mest optimala att så tidigt som möjligt hindra giftet från att absorberas från gastrointestinalkanalen och därmed hindra att det gör någon skada.

According to a decision of the European Commission, measures are to be taken to reduce the use of energy in the EU. The goal is to reduce it by 20 % compared to the current use. This shall be done to the year 2020 (European Commission, 2011). One industry that use large amounts of energy is the construction of buildings which account for almost a third of the energy use (Brogren, 2012). The major part of the energy that is used in the construction industry is not used when the buildings are built, but rather during the rest of their subsequent lifetime.

This thesis has been performed at International Aluminum Casting AB in Eskilstuna,Sweden.International Aluminum Casting is currently working with a number of improvementsin their production in order to achieve their vision of being the leading aluminum foundry in Sweden. As a step in their improvement efforts, focus was directed ondeveloping the company's fixtures for machining.Efforts were focused on two main objectives: to develop a complete proposal on afixture which leads to a more rational use of an assigned part and also form general design advice for development of fixtures in the future.During the work progress, discussions have been made with experts at International Aluminum Casting within the field of fixture design. The objective was to obtain sufficient knowledge about the underlying problems with the current fixture for the part. At this stage of the thesis, a number of essential criteria for fixture design were produced. Information and inspiration were obtained by examining the company?s currently developed fixtures.After gathering the necessary information the process of developing three different fixture concepts started.

In Peter Weiss debut Fra?n o? till o? (1947) the ?I? travels from island to island as a castaway. The island here can signify, or work as a synecdoche for exile and the feeling of isolation that exile often induces. But the movement from island to island also implies a restless state: Peter Weiss shifting from painting to writing to filmmaking and theatre, from German to Swedish and then back to German. The years during exile and the years that followed the exile until his breakthrough in Germany with Schatten des ko?rpers des Ku?tchens (1960), Abschied von den Eltern (1961) and Fluchtpunkt (1962), were the formative years of Peter Weiss authorship.

The study investigates questions and considerations emerging when stone in historic buildings needs to be replaced. The focus is on the surface treatment of stone in sandstone façades in pre-industrial buildings. That means buildings constructed by traditional methods and craftsmanship without the use of modern technology.The research issue originates from the extensive stonework that is planned for the façades of the Stockholm Palace. The project includes the replacement of large quantities of damaged stone to newly cut stone. This raises the questions about the use of modern and rational methods for surface treatment on the replacement stone.

Milk ejection in dairy cows can be inhibited if oxytocin is not released from the pituitary gland. The problem with inhibition of the milk let down is not new, but has recently regained interest. It is observed during different types of emotional stress, for example when cows are moved to an unfamiliar environment, during oestrus, changing from suckling to machine milking or when being milked for the first time. The aim of the study was to examine the extent of cows with disturbed milk ejection in Sweden. A survey was sent out to 1000 dairy farmers in order to collect data about herd size, housing systems and routines at calving and milking.

Due to a constantly increasing competitive pressure it is of great importance to constantly strive for improvements in order to gain competitive advantages. Lean Production is a concept that has been introduced with the aim to minimize waste and increase profitability. The purpose of this report is therefore to investigate how to perform effective planning according to the principles of Lean Production, in companys with customer exclusive products, through a case study at Sandvik Mining and Construction (SMC), and to investigate how SMC kan improve their planning of drifting rods at the production unit in Sandviken.The study started by creating a theoretical framework, to describe the subject planning and planning based on Lean Production. This frame work constituted the base for the case study which took place at Sandvik Mining and Construction, and also for the model and planning tool that has been introduced.The result of the study is partly a general model with factors that contribute to a more effective planning. These factors has beed identifed as SMED, which focuses on reducing set up times and in the end to facilitate the planning.

Aim: The aim of the study was to investigate 1RM and what power could be generated in bench-press and half squat concentric at certain percentages of 1RM. Special interest was put to evaluate men (M) and women (K), strength trained (ST) verses non strength trained (EST) in generating absolute power as well as power relative to 1RM.Method: In total 59 subjects mean (± SD) age 24.9 ± 4.1 years divided into four test groups: 20 male non strength trained GIH-students (EST M), 20 female non strength trained GIH-students (EST K), 10 male strength trained - sprinters on national/regional level (ST M), 10 female strength trained - sprinters (ST K) on national/regional level. They did two tests on 1RM and power in events of concentric bench-press and half squat in a Smith machine. In the first test session 3 ? 5 lifts were made to measure 1RM in each event.
