Mjölkkyl till espressomaskin : Impressive cooler

The project was made in cooperation with Coffee Queen AB, Arvika. The task was to develop and design a new cooler for the milk to Jura Impressa X9, an espresso machine. The good assistance with staff at Coffee Queen and engineers in China and at KPA in Karlstad led to a solution to the problem. It was a long road to get there, many different concepts was developed. When the day came to decide which concept to work with, the choice stood between two different technical solutions.

Utvärdering av AOT för ett pilotskaligt, recikulerat akvakultursystem för fiskodling

With the climate change issues growing in importance on the social agenda, the field of urban masterplanning is of no exception when it comes to minimizing the carbon footprint in a variety of projects. The aim of this thesis has been to prepare the Carbon Critical Masterplanning tool, a software plugin for carbon dioxide emissions assessment developed by Atkins, to be used in Swedish conditions. The main targets were to improve the areas of the tool associated with energy conversion and renewable energy sources, and to test the tool in a real case. A planned construction of a new campus in Albano, Stockholm was chosen for the pilot study. A 3D model was built in the tool and the carbon footprint was calculated for a variety of combinations for energy supply to the future area.

Ombyggnation av ett stall för bundna mjölkkor till boxsystem för rekryteringskvigor

To reconstruct a building is a long-term investment for farmers and it is important that people with different qualifications are involved at an early stage for making the system adapted to the animals as well the animal keeper. Therefore, ethologists who can contribute with their expertise are needed to design the system and get it to function well for the animals.A Swedish farmer who planned to rebuild her stall for tied dairy cattle to a loose-housing system for recruitment heifers for milk production asked me as an ethologist to find a system which can be fit to her existing tie-stall barn for 30 dairy cows, considering the animal needs in terms of movement, social interactions and play behaviors, and to theoretically compare the system with other systems with respect to the behaviors mentioned.The theoretical comparison between different systems was made through a scientific literature review.In agreement with the animal keeper I set out to fit a system with feeding cubicles, a system with cubicles and a system with deep straw bedding to the barn. After measurements were taken and preliminary drawings were outlined it was found that only the feeding cubicle system was possible to fit to the barn.The space provided will limit the animals to perform some playing behaviors. To decrease aggressive interactions between animals even thought a limiting area it is possible to provide partitions between resources animals compete around to prevent that more than one animal can get success to the resource at a particular place at one time. To increase the animal movement in the system the water trays were moved to the outer wall instead of kept in contact with the stalls.Although this report provides guidelines for rebuilding, other competences regarding building construction and a pre-test of the suggested building solution according to Swedish legislation are needed before the rebuilding can start.The results are directed mainly to the owner of the barn, but the literature review can be used by other cattle farmers and might bring increased understanding of the possible effects of different building solution on the animals..

Energianalys av Svensk Växtkrafts biogasanläggning i Västerås

Svensk Växtkraft is the owner of the biogas plant in Västerås. The company is planning to increase their treatment capacity at their biogas plant. In connection to this work it is also possible to make some energy saving changes to the biogas plant. The objective of this study was therefore to make an electricity and heat survey of the biogas plant, a detailed study of the heat consumption in the sanitation step and also a comparison of energy consumption with the present sanitation method and an alternative strategy where the waste is treated in 55 °C during 10 hours (the current method is heating to 70 °C during 1 hour). The energy survey was conducted in close collaboration with staff at the biogas plant. The current during normal operation was measured, power was calculated and multiplied by the time of usage to obtain the energy consumed.

Carbon Critical Masterplanning tool : klimatpåverkan från samhällsplaneringsprojekt

With the climate change issues growing in importance on the social agenda, the field of urban masterplanning is of no exception when it comes to minimizing the carbon footprint in a variety of projects.

The main targets were to improve the areas of the tool associated with energy conversion and renewable energy sources, and to test the tool in a real case. A planned construction of a new campus in Albano, Stockholm was chosen for the pilot study. A 3D model was built in the tool and the carbon footprint was calculated for a variety of combinations for energy supply to the future area. The results show that use of locally installed renewable energy sources can reduce the total climate impact when life cycle perspective is applied.

Effekten av sulforafan på genuttrycket av breast cancer resistance protein i MCF-7 celler

Sulforafan är en isothiocyanat-förening som finns i stora mängder i olika kålväxter. Sulforafan har setts ha en kemopreventiv inverkan bland annat genom att inducera fas II-enzymer styrda av transkriptionsfaktorn nuclear factor E2-related factor-2 (Nrf2). Nrf2 är mycket viktig i cellers skydd mor oxidativ- och elektrofil stress och inducerar uttrycket av många olika gener, bland annat olika tranportproteiner. Breast cancer resistance protein (BCRP) är en av transportörerna som tros induceras av Nrf2. BCRP finns i stora mängder i lakterande juvervävnad men också i många andra vävnader där den transporterar läkemedel ut ur cellerna.

Energy analysis of a fruit drying plant in Adeiso, Ghana

The purpose of the project has been to work out recommendations that reduce the energy-related costs and environmental impact of HPW Fresh & Dry Ltd., a fruit drying factory in Ghana. The factory produces electricity with diesel and biogas but also purchases electricity from the national electricity company. Heat for the drying process is produced from biogas, kerosene and solar panels. In the project the energy system was analyzed by measuring production and consumption of heat and electricity. The project results show that the factory can become self-sufficient on heat if the available energy is used more efficient. The production units for both electricity and heat have low efficiencies.

Genetisk modifikation möjliggör resistens mot mastit orsakad av Staphylococcus Aureus

ABSTRACT. Mastitis is one of the most common diseases affecting dairy cows worldwide. In Sweden annu-ally about 60% of the dairy cows get infected and Staphylococcus aureus cause approximately 30% of these infections. Mastitis causes enormous economic losses. In Sweden, the costs to cure mastitis are estimated to be 192 million SEK per year, excluding the costs for mastitis prevention.

L?ggning av ett kils?gat br?dgolv

This bachelor thesis contains the findings of an investigation into the laying of wedge sawn wood flooring. The advantage of wedge sawn wood flooring is the usage of more material from each board reducing waste. The boards follow the natural profile of the tree where the root part of the board is wider, and the top part is narrower. The technique involves placing boards side by side with adjacent boards in opposite directions. The thick base of one board is neighbored by the narrow top of another, this creates a pattern of wedges in alternating directions, known as a ?root and top? system. Existing literature into this type of flooring is sparce.

Introduktion av förstakalvare i AMS : en enkätstudie

Habituation to an automatic milking system (AMS) for cows in their first lactation differs from habituation to other milking systems. In AMS the cows are supposed to visit the milking station (MS) voluntarily. The milking takes place individually during the whole day, except when the milking system is cleaned. Milking is carried out without any human survey. The aim of the study was to describe the cow?s introduction in AMS in their first lactation.

Strängluftning av vallfoder : Inverkan på ensilagets torkningförlopp, spill och smörsyratillväxt

When harvesting ley you hope to get a fast drying and a faster harvest. If there is a system with round bales, you need to have a dry matter close to 45 %. To make this as fast as possible, there is made a machine which pick up the grass with an pick-up. It turn the grass over and put it behind the machine (figure 2 and 4). There are few tests to prove the efficiency of this machine.

SyfteVårt syfte är att ge en djupare förståelse för det matsvinn som uppstår i livsmedelsbutiker genom att analysera och utreda servicelandskapets, personalens och kundens påverkan på matsvinn. Med koppling till detta syfte har vi valt följande forskningsfråga:På vilka sätt kan livsmedelsbutiker arbeta för att minimera sitt matsvinn med hänsyn till butikernas lönsamhet och kundnöjdhet? MetodDenna uppsats är en kvalitativ studie som haft sin början i ett empiriskt problem som vi ville skapa en djupare förståelse kring, vilket innebär att vår uppsats haft sin början i induktionen. Under processens gång har vi arbetat parallellt med empiri och teori, därför har studien haft ett växelspel mellan induktion och deduktion. Insamlingen av material har skett genom primära och sekundära källor där det empiriska materialet skett genom semistrukturerade intervjuer.SlutsatserI vår arbetsprocess har vi kunnat urskilja att servicelandskapet, personalen och kunden är de faktorer som påverkar matsvinnet inom dagligvaruhandeln.

Hinderbanan - en studie om jämställdhetsarbete och kvinnors förutsättningar inom professionella tjänsteföretag

Although women express a desire to be managers and although they constitute the majority of Sweden's newly graduated academics, they are still heavily underrepresented on senior management level in the Swedish private sector, where men hold as much as 95 % of the top positions. Considering the massive waste of resources that this implies, this thesis sets out to investigate the underlying reasons for the skewed gender distribution on senior management level in two Swedish professional services companies - an industry where the described problem has been palpable. Additionally, the thesis explores the effects of actively working for increased gender equality. With a basis in gender and organization theory, a broad theoretical framework has been compiled and applied to a qualitative case study design. The thesis reveals seven distinct impediments, which together create a parable of an obstacles course, that prevent women from advancing the corporate ladder in the same manner as their male colleagues.

Stadsmöbler för ungdomar :

The title Urban furniture for young people reveals that this paper handles two central phenomenon in landscape architecture; the form and content of the urban spaces, respectively the users and their need for an appropriate outdoor environment in the city. In this paper youth is referred to as 15-18 year olds and the paper is based on theories of their physical use of the city?s outdoor environment. Urban furniture refers to equipment and components in the public room which becomes furniture when people takes them in to claim and gives them a meaning and a function that is useful for the moment. The starting point is that the users, in this case youths, defi nes urban furniture as something signifi cantly more than traditional park furniture, bicycle racks and waste baskets. This paper aims to investigate how the city?s furniture can be developed to meet the youths need to see each other, move and make their marks in the public room. The theories about how youths uses the city are presented in the Theory chapter.
