The purpose of this review was to study the cow eye physiology, focusing on how it registers light, and to see how light affects the cow?s milk yield. It has been showed in studies that more hours of light per day (16 hours of light a day) as opposed to about 9-12 hours of light a day, increases milk yield for dairy cows. This review contains suggestions on how this is connected with the physiology of the eye. Vision is an important sense for many mammals, and is used to check out the animals surroundings. Sensor cells in the eyeball help in turning photons from the light into signals to the brain.

Denna rapport beskriver utvecklingsprocessen av en programvara som jag har skapat för ett företag inom livsmedelsindustrin.

Detta examensarbete syftar till att exemplifiera vilka informationsparametrar som är nödvändiga för att Building Information Management på ett bättre sätt ska kunna implementeras i produktionsfasen. För att uppnå detta mål har vi analyserat utvecklingen och nyttjandet av Building Information Management genom tre olika datainsamlingsmetoder; litteraturstudie, observationer och intervjuer.  I detta examensarbete har vi fördjupat oss i för- och nackdelar samt hur Skanska Sverige AB kan tillämpa Building Information Management som hjälpmedel i arbetsberedningar. Denna fördjupning har lett till att vi kan analysera vilka produktionsanpassade informationsparametrar som en produktionsledare behöver i sin tjänsteroll för att dra nytta av Building Information Management.Vi anser att användandet av en BIM-modell kompletterar produktionsledarens ledaregenskaper, vilket gör det lättare för denne att nå fram med informationen till yrkesarbetarna, då visualiseringen underlättar förståelsen inför aktiviteten. I denna rapport kan läsaren ta del av de slutsatser vi kommit fram till..

To turn the dairy heifers out on pasture is the most natural way for the cattle to get feed. At the same time it is cheap and if it is right treated a feed of high nutritive value. The problem today is to get dairy heifers to grow enough when they are grazing at natural pasture for the entire summer. Therefore, the opinions differ whether pasture is a resource or a problem. The increasing interest of pasture production is due to the fact that you can receive grants for preserving valuable natural assets and cultural landscape elements in the pasture land. A high grazing pressure is necessary to preserve an open landscape and a great variety of species. In the same time the heifers have to supply their nutritive needs in order to grow and be large enough to show heat and be pregnant in right time to calve with a sufficient body size and at an economically right age. This paper includes a literature review on natural pasture, pasture production, and growth of dairy heifers together with own interviews with dairy farmers about their point of view to the pasture husbandry on the farms, how they plan for pasture, look after natural pasture, treatment areas and take care of the calves and heifers. The results indicate that the time it takes and the demanded work are the biggest factors to how and why the farmers do as they do..

This study investigates how nutrients from source-separated human urine from Gothenburg properties can be used as fertiliser in agriculture or for parks or sports fields. The initiator is the Department of Sustainable Water and Waste Management at the City of Gothenburg. Today urine-diverting systems are installed in two apartment buildings and two public-use buildings. Urine recycling is expected to lead to less exploitation of natural resources and less eutrophicating discharges into water recipients. In the study the urine?s market potential is investigated, for which practical handling issues, business aspects and acceptance of customers, employees and visitors have proved to be important.

Pica is a behavior that can be seen in several animal groups. In cats, it means that they are eating, chewing or licking on material that is non-food. In this study the data was collected through an online survey. In total 522 responses, of which 26% of the cats were exhibiting pica. It was found that 28% of the housecats and 26% of purebred cats exhibited pica.

District heating covers around 80 % of the heating demand in apartment buildings and 10 % in single-family homes in Sweden. In the year 2010 the total input of energy to the Swedish district heating grids was about 70 TWh, which corresponds to 11 % of the total energy input to the whole energy system in the country. Through the combined production of heat and power the CHP-plants often reaches an efficiency of 90 % from energy in the fuel to produced heat and power. In order to keep the efficiency high it is important for the owners of the plant to have good knowledge about the plants performance at different operation points. Strängnäs Energi AB initiated this diploma work together with FVB Sverige ab in order to come up with a program for short term planning of the production of heat and power at the company´s CHP-plant.The work consists of three main parts.

During springterm 2010 Erik Persson and Magnus Hansson performed their ThesisWork with DIAB Laholm, in Hallands County for University of Halmstad.The project has been a product development project without exterior customers. Thusit had a great emphasis on functionality and less emphasis on marketing and such.This reflects the ambition to develop machinery to be used within the productionfacilities of DIAB Laholm, not to be sold to exterior customers.Main objective has been to create machinery which enables the production ofrotational symmetric work pieces within a NC-milling machine with 5 axles. Thework pieces milled will be made of DIAB?s material Divyncell with varyingdensities.The project has followed Fredy Olssons method involving Principal ? Primary ?Manufacturing constructions. However a complete manufacturing construction hasnot been made since DIAB just wanted a good Primary construction which will serveas a base for finishing touches at DIAB.By the end of the project material including calculations has been sent to DIAB andthey will finish the work and manufacture the machine if they find economic viabilityin this.The work method has been suited for this by several reasons, it was created withthese projects in mind and it?s also the method most familiar to us..

Background: The global responsibility for multinational companies is a current matter of subject. Now when the world increasingly is getting globalized, economic growth is created, which brings a bigger demand of responsibility on companies. The leading companies from every industry is often becoming the frame for how the production process works and is therefore exposed to outer pressure which, for example, is coming from consumers and the media. Since consumers at present are more aware of what they are buying and where it comes from, it is important that the companies take social responsibility. We have therefore studied three big companies within the clothing industry to see in witch way they are taking their social responsibility.Purpose: Our purpose was to explore how companies within the clothing industry describe their work with Corporate Social Responsibility, code of conducts and where the incentive behind this work is coming from.Method: We have, through a qualitative study, examined how three large companies work with Corporate Social Responsibility.

The purpose of the project was to exam steams ability to sterilize carrots infected withLactobacillus plantarum. The project was a cowork with Brämhults Juice AB. They hadobserved an increase of Lactobacillus in the production of carrot juice during the summer. Tokeep the flavour of fresh fruits, the juice is treated carefully with heat. This means that thejuice only stays fresh for a few days, around two weeks for an unopened package and threedays for an opened package.In an attempt to remove the remaining Lactobacillus of the carrots, steam is tested as an extrastep in the production of juice.

The competition policy in the EU should guarantee that the competition is not distorted in the way that would prevent or create difficulties for the free mobility of goods and services between Member states. It is prohibited for companies to abuse their dominant position according to Article 82, if it affects trade. The essence of Article 82 is control of market power. The perfect competition results when supply and demand appoint the price and quantity of a product. Firms are encouraged to compete then it results in efficiency, quality products and lower prices.

In Uppsala CHP Plant, there are six pressure reducing valves to reduce the pressure from 15 to 3 bars, before six absorption heat pumps. During the process the energy is conserved but losses occur in form of exergy. The aim of this thesis is to reduce the losses of exergy. This can be done by letting turbines replace the pressure reducing valves.In this thesis an investigation has been done of the conditions today, the conditions after the change from pressure reducing valves to turbines and a comparison of three different types of turbine solutions. The three examined solutions are one turbine, several helical screw expanders and several small turbines in parallel with asynchronous generators.The six absorption heat pumps have been divided into two groups; one group of four and one group of two absorption heat pumps.

In recent years the construction industry has been exposed to increased time pressure which has resulted in a higher amount of wastage. Today 35 % of all construction projects in Sweden is "wasted". Time pressure has risen due to increased competition on the market, with more actors entering the construction business, therefore profit margins decreased which has led to a more pressing need for decreasing the amount of wastage.Bravida is Scandinavia's largest supplier of installations and provides specialist services in electrical installations (heating and sanitation), and ventilation. Mahdi Bawaqneh's task was to investigate where, how and why wastage occurs in the company's projects and how to prevent such wastage. The thesis covers the subjects of lean production, communication in projects and planning of projects.
