Our project is divided into two parts, one production and written report. The main focus was the production part, were we used PHP to create simple solution for handling SMS and MMS with direct communication with the mobile operator server. We communicate with sockets and can handle CIMD2 and MM7 protocol. To get our components easy to use we have created two classes to handle SMS and MMS. To demonstrate our technical platform we created a website were you can create an account.
Svenskproducerat proteinfoder till slaktsvin
Soybean meal from South America is the most common protein feed used for animal production in Sweden. Production of soybean has negative effects on the environment and the transports from South America to Sweden causes considerable CO2 emissions. Therefore it is a growing interest in locally produced protein feed in Sweden. Protein feeds that are possible to grow in Sweden are rapeseed, peas, faba beans and lupins. Those are adapted to the Nordic climate and are perfect to grow in cereal rotations.
Nötköttsproduktion i Västerbotten
Beef production in Sweden has traditionally been about rearing of dairy calves to slaughter. With reduced number of dairy cows and accordingly less dairy calves for slaughter, there has been a need for new forms of beef production in Sweden. In Västerbotten there are good conditions for beef production with a high feeding level of roughage due to favourable climate. The aim of this thesis is to, through interviews with ten farmers with beef production in Västerbotten, study what and with how much they feed their animals and link the results to production level. The thesis begins with a literature review where the general feeding standards and feeding recommendations for beef cows and growing cattle are examined.
Uthållig estetik i landskapet - om att synliggöra sitt förhållningssätt till hållbarhet : Sustainable landscape aesthetics - to demonstrate ones attitude towards sustainability
Abstract
In my work, I have tried to define and clarify the conception of sustainability seen from my perspective as a landscape architect. With a basis in literature studies, I have analysed and commented on different applications, contents and meanings of sustainability and endurance. This compilation is based on how a number of writers, researchers and authorities consider the importance of integrating ecological, social and economic aspects of sustainability in city planning. My perspective has mainly been founded on the anthologies and compilations from the 80´s and 90´s where Per G. Berg and Björn Malbert acted as editors.
Koldioxidlagring - realitet eller utopi? : En komparativ fallstudie med syfte att undersöka potentialen för koldioxidlagring i geologiska formationer och biologiska sänkor och dess förmåga att bidra till hållbar utveckling
To curb greenhouse gases and mitigate climate change is one of the biggest challenges human society face today. Carbon dioxide (CO2) has accumulated rapidly in the atmosphere as a consequence of burning of fossil fuels and deforestation. The aim of this study is to explore two methods to store carbon dioxide in geological formations and biological sinks. The aim is also to discuss the two mitigation options from a sustainable perspective and whether it can lead to a better environment and benefits for local and global societies. The research questions are: Which method to store carbon dioxide, geological or biological, is the most effective? Which method to store carbon dioxide, geological or biological, has the greatest potential to promote sustainable development for local communities?The method used is a comparative case study and presents four case studies that explore the potential for CO2 storage offshore in Norway and Brazil; and in tropical forests in Mexico and Brazil.
Lantbrukaren som energiproducent : en fallstudie i energisatsningar inom lantbruket
The intrest and development of bioenergy and energy from renewable sources in Sweden has increased rapidly over the last few years. There are a whole lot of alternatives for those who would like to venture and invest in renewable energy production.
Production of renewable energy opens up many opportunities for forestry and farming to venture a new branch of production, on basis of the primary production. Several of the new energy sources grows on farmland or in the forest. The opportunities exist in the primary products, as well as in refining and reselling, in the value chain of energy.
The starting-point is the Farmer as an energyproducer. This master thesis studies the nature of farmer-own firms, who has invested in production of renewable energy.
Spänningsstyrd underfrekvenslastfrånkoppling i elektriska kraftsystem

This report presents a comparison between conventionalunderfrequency load-shedding and this new method for load-shedding.
Röd Glöd : Granaternas betydelse under yngre järnålder med fokus på Gamla Uppsala
During an excavation at Old Uppsala 571 raw garnets was found. In comparison with similar fragments from other sites in Sweden my aim was to prove a completely domestic production of garnets for cloisonné work. I have chosen to look at the archaeological sites of Old Uppsala, Valsta, Slöinge and Paviken and more closely at the material from Old Uppsala and Valsta. My theoretical framework has been to look at the garnets own agency in the contemporary society.Garnet cloisonné was a popular jewellery form during the Merovingian period on the continent although it came to an end in the early 7th century. It was during this time in Scandinavia a new sort of garnet, technique and paste was introduced and the garnet cloisonné was profoundly used for the gear of the elite and ritual objects.
Funktionsupphandling av solelanläggningar
This thesis aims to contribute to improved functional procurement of photovoltaic systems, PV systems. Functional procurement means that criteria concerning a function are set rather than specifying technical details or products. Possible advantages and difficulties in using functional procurement have been analyzed by interviews, simulations and a case study. Electricity production and surplus production for different scenarios have been simulated via MATLAB. The MATLAB script was also used to generate rules of thumb on feasible solar fraction for six different load profiles; a church, a farm, a car mechanic, an office, an industry and an apartment building.
Skördemetoder av industrihampa :
Hemp is an old agricultural plant and has been used for hundreds of years for making
textiles, ropes and other fibre products. In the middle of the last century the Swedish
government prohibited all growing of hemp. Natural fibres were replaced by syntetic
fibres instead. Today there is a newly awakened interest for using natural fibres from
renewable materials. Growing of industrial hemp for fiber is allowed in Sweden
again.
I want in my Paper give Swedish growers an insight of which harvesting methods that
have been tried in Sweden and how they worked.
Locally produced pork ? Västra Götaland
The interest for locally produced food has increased the last couple of years, and some consumers have a willingness to pay a premium for niche products like locally produced food. At the same time it seems like the Swedish pig production are in a negative development period. This study tries to see if locally produced pork could be a possible factor which might affect producers in the county of Västra Götaland views on different aspects regarding their production. Consumers of pork and their point of view regarding locally produced pork were also studied. Surveys to consumers and producers were constructed.
Although previous studies claim the opposite, in the two locations (Högsäter and Uddevalla) where the consumer survey were performed, there were more men than women that always bought locally produced pork.
Utvärdering av Naturvårdsverkets bedömningsgrunder för makrofyter i sjöar
According to the Water Framework Directive of the European Union, macrophytes should be used as indicators in the ecological and environmental monitoring of lakes. In the member state Sweden the Environmental Protection Agency has elaborated assessment criteria for determining lake status based on macrophytes. The main focus of this thesis is to evaluate the efficiency of the assessment criteria for macrophytes. In addition the concordance between the ecological status classes of the four quality factors included was analysed.The assessment criteria for macrophytes are based on the total phosphorus preference of the respective species. The focus is thus mainly on the nutrient level of the investigated lakes and the environmental problem monitored is eutrophication.
Local poultry production in rural Zambia and the effect of light on poultry performance
Zambia is a country in Southern Africa where poverty is widespread and the traditional keeping of local poultry therefore plays a crucial role in improving nutrition. Meat and eggs from poultry are important sources of protein but also of income. Improving the poultry production is thereby a method to fight poverty. For poultry, the access to light is an important factor for both growth and egg production. In this paper, the focus is on the traditional village chickens used for both egg and meat production, how they are kept, their health and welfare and if the use of a solar lamp will influence their behaviour, growth and egg production.
Three studies were conducted in Chibombo and Choma Districts in Zambia were 17 farmers were interviewed regarding the village chicken management of which six farmers participated in a solar lamp experiment.
Stadsodling : möjligheter och begränsningar
Urban farming can be viewed in several contexts. The first part of this work brings up the beneficial effects of farming on our physical and mental health, knowledge as well as on social life in cities. The introduction of gardening in schools can contribute to an increased awareness on both agricultural practices and importance as well as ecological processes. It can also be used in teaching of other subjects. Farming can also contribute to improving the household economy, and the economy on a municipal or national level.
En studie om Lean Production som effektivitetsteori i virkesanskaffningsprocessen : ett hjälpmedel för ökad effektivitet med kunden i fokus
Effektivitet är för många organisationer ett begrepp som förknippas med att utnyttja sina resurser maximalt. Detta är något som även är märkbart inom svenskt skogsbruk, där man idag är mycket mån om att vara resurseffektiv i sin verksamhet. Det finns dock fler innebörder av effektivitet som begrepp. Toyota, med sitt Toyota Production System, och lean production har bevisat att en flödeseffektiv process med kundfokusering kan vara ett framgångsrikt arbetssätt.
Denna studie tar upp lean production som teori i svenskt skogsbruk och knyter an denna mot virkesanskaffningsprocessen.
