Ergonomiska förhållanden för mjölkare i olika mjölkstallar :
Earlier studies of musculoskeletal problems with milkers working in milking parlour
operators have shown that it is a physically demanding occupation. The extremities that are
most exposed are neck, shoulders, hands and wrists. Those systems that have been studied in
present cases are fishbone and some tandem barns.
There have been changes in the working environment during the past ten years. The
mechanisation has been developed for the better with automatically removers of the milking
units and vertically adjustable floors in almost every daily milking barn. In other hand the
milk production are more industrialised and more related to stress today.
Effektiva godstransporter : kartläggning av bakomliggande faktorer på transporters utförande
The society of today can?t manage without transportation. We need transports to getfood, to go to work and to create new products. The transportation ofgood is thus an important part in the function of the society and they?ll increase, bothin number and in amount.
Turbiditet som ersättningsmått för totalfosforhalt i kustmynnande vattendrag i Östergötland
Eutrophication is a major problem in the Baltic Sea, as a result of increased loading of nitrogen and phosphorus. In the coastal parts of Östergötland the soil largely consists of clay and contains high levels of phosphorus bound to clay particles. Erosion of the soil in agricultural areas makes the water turbid and transports phosphorus to the Baltic Sea. The aim of this project was to examine the relationship between phosphorus and turbidity in the coastal streams of Östergötland. The aim was also to evaluate the possibility to use turbidity as a surrogate measure for phosphorus.

Transportation of pigs might be a welfare problem. Stress during and after transportation can negatively affect the meat quality or cause carcass damages, which leads to major economic losses every year. The transportation chain can be divided into several stages; loading, transport and unloading. This literature review focuses on unloading of pigs from a transport. When arriving at an abattoir pigs can be fatigued and need to be as smoothly unloaded as possible.

Städer och planetära gränser : En utvärdering av Stockholms ochNorra Djurgårdsstadens påverkan påde planetära processerna
The concept of planetary boundaries was introduced in the year 2009 by a group ofresearchers led by Johan Rockström and Will Steffen. The group presented a draft of thelimits of the planet regarding nine Earth System processes concerning climate change, oceanacidification, stratospheric ozone depletion, atmospheric aerosol loading, interference with Pand N cycles, global freshwater use, land-system change, rate of biodiversity loss andchemical pollution. The starting point for the study presented in this report was that asustainable development only can be achieved if humankind stays within the boundaries. It istherefore, based on the ongoing urbanization, relevant to evaluate how cities affect the EarthSystem processes. The aim of the study was to investigate if Stockholm Royal Seaport (NorraDjurgårdsstaden), a district in the northeast of Stockholm with a clear environmental profile,affects the Earth System processes less than Stockholm in general does.
Vidhäftning mellan prefabelement och pågjutningsbetong : Undersökning hur skrovligheten påverkar vidhäftningskapaciteten vid skjuvning
Self-compacting concrete has soon been around for a decade. Recently the prefabrication industry has started to use this fairly new concrete type in larger scales, mainly because of its distinctive properties. There are still certain areas that need to be thoroughly examined, such as bond capacity. There have been very few studies regarding shear capacity due to the fact that the procedure is complicated.This report will highlight a method to examine the shear capacity of different surfaces that have been prewetted as well as non-prewetted surfaces. The surface areas follow BBK 04?s and Eurocode 2?s demand for surface roughness. A smooth surface will be completed in order to confirm if the different shapes influence the bond strength by shear stress or not. The purpose of this essay is to measure the bond strength within the shear capacity as well as examine the impact it has on surface roughness and treatment for shear bond.The method used to identify the shear capacity is called L-shaped Push-Off Test.
Plantetablering och tillväxt för sådd och planterad tall 2-5 år efter markberedning med harv eller Huminmix-teknik inom Holmen Skog distrikt Norsjö :
The objective of this work was to compare the environmentally gentle soil scarification technique Huminmix (with possibilities to do track-grinding/HMMspår, long-scraping/HMMlångfläck and mounding/HMMhög) with conventional disc trencher, concerning seedling establishment and growth of direct seeded and planted Scots pine seedlings. Inventories were made during June and July 2005, in 34 seeded and 6 planted stands from 2000 ? 2004 (1- 5 years old) of lichen- and myrtillus/vaccinum-type in Holmen Skog AB´s district Norsjö in Västerbotten. The Huminmix-technique had been used for HMMspår in the seeded stands and for HMMhög in the planted stands (HMMlångfläck has been used from the year 2006 for direct seeding). The studied stands had been seeded with the same amount of seeds according to stand data.
KOLHYDRATUPPLADDNING I SAMBAND MED OPERATION UR ETT OMVÅRDNADSPERSPEKTIV
Att kolhydratuppladda är att fylla kroppens muskler med energi, vilken används för att patienten ska klara av kroppens stressrespons i samband med fasta och operation. Kliniskt får patienten dricka näringsdryck innan operation för att kolhydratuppladda. Inför ett kirurgiskt ingrepp genomgår patienten en förändring i vardagen, lämnar hemmet och kommer till en ovan miljö. Att patienten genomgår fasta och upplever en ny situation påverkar patientens välbefinnande negativt, med både hunger, törst och oro och så vidare. I denna litteraturstudie kommer tio artiklar att granskas för att undersöka, effekterna få en preoperativ kolhydratuppladdning fokus i studien ligger på omvårdnad och välbefinnande men den tar även upp effekter som inte är direkt relaterade till omvårdnadsämnet men knyter an till vården.
Hantering och lastning av nöt på gården : praktiska studier vid hämtning av slaktdjur - råd för att minska stress och skador på djur och människor
ABSTRACT
There is present a lot of focus on animal welfare issues during transport and the related
loading and unloading of animals. This thesis is a field study investigating the present
situation of beef and dairy farms in Sweden. The predominant reasons stressing cattle when
transported to abattoirs are when they are loaded and unloaded on the trucks. The aim of this
thesis is to improve the handling and the loading facilities to facilitate the handling and
reduce the stress for the animals as well as the personnel.
The field study was done by travelling together with the transports from the farm to the
abattoir in Uppsala. Three trucks where used and about 60 farms were visited January to
March 2003.
Undersökning av svetsförband med avseende på svetsgeometri, diskontinuiteter och blästring med stålkulor
Breakdowns of welded structures are usually a consequence of fatigue loading. Fatigue fractures are commonly initiated in the region close to the weld toe but can also initiate from the weld root and from discontinuities inside the weld. The purpose of this investigation was to examine the weld quality of welded joints produced at Volvo Wheel Loaders factory in Arvika. The goal of the investigation is to give a clearer insight regarding factors influencing the fatigue strength of the welded joints and thereby give a better foundation for fatigue strength calculations.The investigation is including examination of the weld geometry, weld discontinuities and the effects of shot peening. Mainly three different methods for collecting test data have been used: Plastic replicas cast on the weld profile, weld specimens from a rear frame belonging to a wheel loader of model L110E/120E and Almen testing of the shot peening.The results showed that it is not possible to control even transition between the weld material and the base material without after treatment.
Utveckling av instyrningsfunktionen hos ett dockningsinterface
In this project the task has been to develop a product that will facilitate an operation for personnel working in a sterilization center. The operation is to steer the front of a loading trolley into the chamber of an autoclave, a so-called docking. The moment is complicated because the margins to deviate from ideal docking position and still succeed, is very small.The principal Getinge's desire was that the product could be retrofitted at the customers on their existing systems. One of the demands was that the product should fit two types of trolleys, one with a adjustable working height and one with a fixed working height. Getinge is supposed to purchase the system from a subcontractor who shall manufacture it and the requirement from Getinge is that the cost of purchase mustn't exceed SEK 500Initially principles, solving the problem was developed.
Framtagning av en rörväxlaretill sopsugsystem
The main goal of this project was to develop some sort of a diverter for pipestransporting waste in a vacuum system. This unit was supposed to be both cheap andeasy to serve/exchange worn out parts. With a limited space to install the pipeexchanger, the challenge was to keep it as compact as possible without constructingbends with to small radius or to sharp angles as this would wear out the system a lotfaster than planned. The system was also supposed to be able to handle clothes andscrubs from hospitals. Having too much sharp edges or angles would tear the clothesapart.
FE-modellering av hjullast på sandwichpanel
This bachelor thesis in mechanical engineering was performed during the spring2015 in collaboration with Composite Consulting Group in Laholm. TheComposites Consulting Group works mainly with design and details of differentcomposite projects, their main area is FE-calculations, 3D-modelling andmechanical tests with composite materials.The aim of this bachelor thesis was to simplify the calculation process of solidmechanics for sandwich panels by simulation with computer software. The goalwas to decrease the time for the design and calculation process of the constructionand the cost of the practical tests. Our task was to build a static three dimensionalmodel with the computer software Abaqus, where the result should correspondwith the practical pressure tests in laboratory.The project started with collection of material data from Composites ConsultingGroup and by learning the software Abaqus, simultaneously a specification wasdeveloped in corporation with the company. Later on, a static wheel pressuremodel in the software Abaqus was produced which simulated the behavior of thesandwich panel during static wheel-pressure by a pallet truck.
Kartläggning och effektivisering av ljuddämparflöde
In 2013 a new emission standard for heavy trucks was introduced and hence a number of new parts was brought in to Scania CV AB. This created a need for modifications in the silencers flow. The flow is highly complex involving several suppliers, call off methods and different models of silencers. The aim for this project was to improve the existing silencers flow. The flow, from supplier to assembling, has therefore been mapped.
