Sha Jun

The agriculture in Sweden today uses chemical substances to control vermin, weed and diseases. This usage shows through polluted subsoil water and trace elements in the food we eat. There?s a risk that additional symptoms will arise in the future. Our product Sha Jun, developed in 2006-2007, is an attempt to try and minimize the need of chemicals in the agriculture. The idea started with the attempt to minimize the usage of pesticides on the cropland.

Småhusutformning och solenergiutnyttjande

This paper goes through solar energy and what uses it has. It is also a guide in the choice of solar collectors forthe real estate that I have drawn for the thesis work.Solar energy is a renewable source of energy from the Sun's light. Energy can be used to produce both heat andelectricity through solar collectors and solar cells. Some of the benefits of solar energy is that it is completely freeto extract, environmentally friendly and virtually maintenance-free. Disadvantages are that the technology isexpensive, does not cover the entire energy needs and takes a long time until it pays.

Slaktsvins basala behov i kommersiell uppfödning : Slaktsvins basala behov i kommersiell uppfödning oönskade beteenden, skador och välfärdspåverkan

The Swedish Welfare Act § 4 says that "Animals must be kept and cared for in a good environment for animals and in such a way that promotes their health and allow them to behave naturally." Pigs in the wild spend 80% of their waking hours walking around and rooting for food, eating and exploring their environment with its snout. Fattening pigs in commercial farms spend 80% lying doing nothing. A lactating sow is lying down most of her day, and only 10-20% of the body surface is in contact with the floor, so the pressure is high on these spots. Piglets lie down and paddle with their legs, with high liquid content in the tissues, several times an hour, to stimulate and massage the sow's udder. In the existing system, these individuals are held more often on floors that are anything but inviting to sleep on.

Incitament för fastighetsägare att omvandla bruna kontorsfastigheter till gröna - När och varför de väljer att investera

This thesis of 15 hp has been implemented at Halmstad University, in collaboration with Saab Dynamics in Linköping. Saab Dynamics is a company operating in the defence industry where competition is tough. This necessitates new ways to increase efficiency in the company, which is the basis for this thesis. Saab Dynamics wants to introduce simulation driven design. Since Saab Dynamics engineers have little experience of simulation, required a user methodology with clear guidelines.

Småskalig säsongslagring av solenergi för uppvärmning av bostäder : Simulering av lagerutformning och konsekvensen av adderade uppvärmningsbehov motsvarande en pool och ett atrium

The sun is a huge energy source with great potential of providing energy to the heating of homes and other buildings in an environmentally sustainable manner. In order to provide buildings with energy from the sun it is necessary to transfer the energy supply over time to when the demand arises. By storing the heat in a seasonal storage, solar energy from the summer can be used in the winter when the demand for heating is greatest.Today's existing plants are mainly in Europe and particularly in Germany. These facilities are designed to supply heat demands greater than 400 MWh and covers about 40-50 % of this need which consists of energy for space heating and domestic hot water. How much of the heat demand that is covered, the solar fraction, is partly due to losses from the storage which in turn is connected to the surface area of the storage.

Har du blivit lurad? En studie i hur reporäntan påverkat bankernas utlåningsräntor under finanskrisen 2008

Hösten 2008 domineras nyhetsflödet av rapporter om den finansiella kris som under årets senare hälft drabbat världen. Samtidigt finns en utbredd oro om en långvarig recession. I sådana lägen, då landet befinner sig i en lågkonjunktur, försöker Riksbanken stävja den genom att sänka räntorna och öka den ekonomiska aktiviteten i samhället. Reporäntesänkningarna under oktober fick dock en begränsad effekt på bankernas utlåningsräntor vilket ledde till en medial storm mot bankerna. Samtidigt gick finansministern Anders Borg ut med ett pressmeddelande om att alla privatpersoner borde ringa sin bank och kräva sänkta bolåneräntor.

Teknik för biogasanvändning

This thesis is made by Carl Persson and Alejandro Saavedra for Gryaab. Gryaab is Gothenburg?s water processing plant and produces about 60 GWh biogas annually with a flow around 1150 Nm3/h. Gryaab wants to research their possibilities to become independent with electrical energy and the possibilities to enrich, upgrade biogas. The use of methane rich gases like biogas and natural gas is today low in Sweden compared to major parts of the world.

Utveckling av samhällets sårbarhet och hanteringsförmåga över tid : PAR-modellen som verktyg för identifiering av säkerhetshöjande åtgärder och förhållanden

Under senare år har verkställande direktörer omsatts i allt snabbare takt. Fenomenet kallas för VD-karusellen och syftar till att verkställande direktörer får ta allt större ansvar för utvecklingen på börsen. Marknaden i sin tur värdesätter den verkställande direktören vilket skapar reaktioner vid successioner. Detta kan anses paradoxalt eftersom den verkställande direktören påverkar hur marknaden värdesätter honom/henne.Syfte: Utifrån teorier och tidigare management forskning avser studien beskriva hur marknaden reagerar på successioner. Detta kombineras med hur företagen presterar efter successionen är genomförd.

Miljöteknisk undersökning enligt MIFO : en studie på fastigheten Bodsjölandet 1:14 avseende den nedlagda tjärfabriken i Grötingen

During 40 years of industrial production, from the end of the 1890?s until the end of 1930?s, coal and wood distillation products were manufactured in AB Carbo?s tar factory along the River Gimån in Grötingen, in the county of Jämtland, Sweden. In accordance with the Swedish Environmental Protection Agency?s Methods for Inventories of contaminated sites, MIFO, the site in Grötingen has been identified as a potentially contaminated site. In order to determine whether toxic substances pose a threat to human health and ecological systems in the area, there was a need to investigate the presence of contaminants, their levels and potential for migration.

Feng shui i trädgården :

Our environment affect us, not least gardens. By practising the ancient Chinese art feng shui, one could find tools how to create harmony and balance in gardens. By paying attention to different energies working with colours, shapes and materials one can create a nice garden with good feng shui. The philosophy, however, includes much more than what plants or what hard materials to choose in the garden. It describes different energies, the movement of energies, which we can learn to live in harmony with.

Reglerstrategi för fria ventiler : ? Utveckling av en fyrtakts förbränningsmodell för att prediktera optimala ventilinställningar

As emission legislations across the world continuously pushes engine development forward,engineers constantly need to come up with and implement fuel saving technologies. During thelast decade, variable cam phasing has become a popular solution to increase gas exchangeefficiency. This configuration is typically mechanically constrained by camshaft limitations, anda solution to circumvent this problem would be to use a different valve actuation principle.One example of this is to use pressurized air controlled by electrical solenoids. Such a systemhas been developed byCargine Engineering and this provides the starting point for this work. Tobe able to operate the valvetrain on an actual engine, a control system is needed.

Återuppbyggnad av strukturer efter en kris

Sammanfattning Titel: Återuppbyggnad av strukturer efter en kris Författare: Lisa Mattsson, Emma Lindmar Handledare: Camilla Wernersson Institution: Managementhögskolan, Blekinge Tekniska Högskola Kurs: Kandidatarbete i Företagsekonomi, 10 poäng Syfte: Syftet med denna uppsats är att ur ett meningsskapande perspektiv bidra till en ökad kunskap och förståelse om hur interaktioner mellan människor i en organisation kan återuppbygga strukturer efter en kris. Metod: För att nå vårt syfte har vi valt att arbeta med kvalitativa metoder. Vi har genomfört en gruppintervju med personal från hemtjänsten i Kronobergs län, vars strukturer rasade samman under stormen Gudrun. Vi undersökte hur de efteråt återuppbyggde strukturerna genom att analysera olika teman ur empirin. Slutsatser: Osäkerhet, samhörighet, roller, beslutsfattande och rationalitet, är teman som alla är länkade till varandra, till strukturåteruppbyggande och till meningsskapande. Detta resonemang leder till slutsatsen att meningsskapande kan underlätta för strukturåteruppbyggande, och strukturåteruppbyggande kan i sin tur underlätta för meningsskapande.

Method: To achieve our purpose we chose a qualitative method.

Rätt gåva för rätt tillfälle

This master thesis is a study of the Swedish hydropower capacity to balance wind power. The Swedish government has decided that it should be possible to produce 30 TWh from wind power in the year 2020. The Swedish municipalities have to have plans for wind power plants with total yearly generation of 30 TWh. Wind power is an variable energy source that needs to be balanced by other energy sources. In Sweden the Swedish hydropower can be used for balancing a large scale introduction of wind power.

Försäkringsbolags kostnader för reparation av fuktskadade badrum

The purpose of this report is to compile and examine the cost of renovation of moisture-damaged bathrooms, to derive a target price. The target price can then be used by insurance companies to estimate the ultimate cost of future bathroom renovations.       The method is based on the compilation and comparison of the cost of repairs of previous water damage in bathrooms. The calculations compiled based on repair estimates for different insurance losses from one of the leading insurance companies in Sweden.       The result shows the average price per square meter of floor area for different sizes of bathrooms. The average price is the basis for the estimate of future renovation costs of bathrooms. The results further show that the bathroom finishes, area and the distance between the entrepreneur and the location of the renovation have great impact on the final repairing cost.
