The bioavailability of soluble oxalates in stir-fried silver beet leaves
The prevailing food and energy crisis of the world, due to the declining reserves of fossil energy and a never ending rise of consumption, forces us to look into new fields to supply our energy demand. The boom of bio energy is criticized, as food crops are used to provide biodiesel and ethanol and the volumes are ridiculously small to supply world demand. Algae are one of the world?s oldest life forms and exist in many different phyla, providing a great variety to choose from, for different purposes. Cultivating microalgae offer a way to produce energy at great volumes without competing with food production and at the same time the algae offer a way to use our expensive nutrients in a more efficient way, besides this the algae are carbon dioxide neutral since their carbon source can be supplied by the atmosphere and the additional energy required can be supplied by algal oil or other renewable sources.
Trådlös energiöverföring via elektromagnetisk induktion
This paper describes a method for wireless energy transfer via near-field electromagnetic inductionthat is inexpensive, simple and can be applied to almost any type of system, regardless of size andenergy demands.The method uses a primary unit consisting of an oscillator, amplifier and inductive coil thattransfers energy to a secondary unit consisting of a coil, rectifier and voltage regulator. Two typesof oscillators and several amplifier designs were realized and evaluated together with a multitudeof flat coils of both monofilar and bifilar type.The results show that it is important to use an oscillator whose frequency is dependent on theinductance of the connected transmission coil, such as the Colpitts oscillator. This is preferable toan oscillator with a preset frequency, such as a Schmitt-trigger oscillator..
Identifiering av slöserier på Lundbergs Plåt AB
Lundbergs Plåt AB is a small company situated in Jönköping. Their main task is to process different kinds of steel such as stainless steel. Lately, they have shown an interest in Lean production.On the basis of the situation mentioned above, we developed the purpose to find and decrease the non value-added wastes in the production at Lundbergs Plåt AB. Out of this, we also developed and answered two questions: Which wastes can be found with help from a value stream mapping (VSM)? In what way can these wastes be reduced and how can these reductions contribute to an improved production? VSM is the method used to find the non value-added wastes.
Svenska mjölkbönder, snart ett minne blott? - Markbygdens mjölkbönder i tankar om mjölkproduktionens nuvarande situation och framtidsutsikter
Major changes within the agricultural politics today have forced the dairy production to scaleup, in order to compete on a global market. This has resulted in a reduction in the number ofsmaller dairy farms in Sweden, from about 40000 to just over 4000 over the last 30 years. Thepurpose of this study Svenska mjölkbönder, snart ett minne blott? ? Markbygdensmjölkbönder i tankar om mjölkproduktionens nuvarande situation och framtidsutsikter, is topresent the opinions of dairy farmers in Sweden, regarding the Swedish dairy industry and therelation to their own dairy production. A secondary purpose is to problematize how theconsequences of pastures and cultural landscapes influences human society as dairy farms andgrazing animals are becoming fewer.
Nitrogen flow in Scania : substance flow analysis on a regional level
In this thesis, the flows of reactive nitrogen (Nr) in Scania were investigated and quantified. The thesis was also intended to form a basis for comparison between the urban nitrogen flow and other flows of nitrogen within Scania. The management of nitrogen in society has disturbed the natural nitrogen cycle. This is linked to a series of environmental problems such as eutrophication, acidification, global warming and smog.
The method used was Substance Flow Analysis (SFA) for Nr. For calculation and flow charts Scania was divided into three subsystems; air, water and society.
Collaboration to address a wicked problem : the case of certified palm oil
Corporations meet complex challenges as they operate on a global market. Global multidimensional problems are referred to wicked problems and which cannot be solved only
managed. In this case, of certified palm oil, palm oil production can be seen as a wicked problem due to deforestation of rainforest, land grabbing and social conflicts. There are also conflicts regarding the value and interest of palm oil.
This thesis investigates the Swedish transformation for certified palm oil and how actors in the Swedish food market address this transformation to have certified palm oil in their production. The aim of this thesis is to explain enabling factors to address the governance gap
of ethical sourcing in the food industry.
Intäktsfördelning och ansvarsenhet : En studie av hotellrestauranger
Writers: Johan Lundqvist Eriksson and Elin SandbergSupervisor: Stig AnderssonEnglish title: Allocation of revenue in the hospitality industryKeywords: Revenue allocation, cost allocation, profit center, Du Pont model, taxes and manipulation of data.Date: January 2012Since the taxes for food and lodging has been different in Sweden for many years, the hospitality industry has come up with a way to save money on tax paying. When private customers stay for a weekend where the meals are included, the business is placing more than the relevant revenue on the lodging part, which has the lower tax. Because of this the results has improved and tax money has been saved. Now when the Swedish government has decided to lower the tax on food to the same level as the lodging, the chances for correct revenue allocation arises. When we approached the hospitality industry with our problem area a big interest was showed from the head chefs. They now see a chance to get more income on the meals and through this be able to show better results towards the owners.Two hotel managers at two different hotels and their head chefs were chosen for interviews.
Energikartläggning av Fridhemsskolan 16:2
Increased energy consumption in the world has created an increased supply of various fuels, especially fossil fuels. The Swedish government has set up various energy targets for 2020. To reach these goals it?s important to increase the energy efficiency in local buildings such as schools. This work illustrates the breakdown between energy supply and energy losses over the school.
Generationsväxlingen ? De gamla ska man ära, de unga ska man lära?
Aim: The aim of this study is to examine how managers apprehend today's leadership and how they believe that future leadership will be influenced and developed when the people bourn during the nineteen forties pass on their management positions to a younger generation.Method: I share the hermeneutic view on science. I believe that knowledge is born with in the person who seeks to obtain it. I have chosen to conduct my study using a qualitative and inductive approach. I use an inductive approach as I answer my questions by using interviews in order to respond to my question at issues, and assumes from the empiric in my study.Result & Conclusions: The leadership role has changed from being? the one who decides?,? the director?, to becoming less peculiar and prestige.
Balladspår i modern svensk litteratur : Intertextuella influenser
The purpose of this study is to investigate the distribution of medieval ballads as semiotics of intertextuality in modern Swedish literature, here represented by August Strindberg, Erik Axel Karlfeldt, Kerstin Ekman and Katarina Frostenson. They are famous authors from different epochs, ranging from the period called ?the modern breakthrough? in the 1880s until the postmodernism of the present time. My aim is to expose their attraction to medieval balladry, and their different ways of using form, language and style from this old poetry in poems, prose and plays, explicit as well as implicit..
Svängda hyllor - den raka vägen till en attraktiv butik? En kvantitativ studie om konkava hyllors effekter på kundens perception av sortimentet, upplevelse av butiksmiljön och köpbeteende.
Due to the harsh competition among Swedish food retailers, in-store marketing is a crucial component in the stores marketing strategy. In an attempt to differentiate among its competitors, COOP Sweden has begun to use concave store shelves. Although the food retailing industry is one of the most studied, no research has been conducted on the concave store shelves. The objective of this study is to describe how these shelves effect the customer perception of the assortment, their experience of the store environment and their buying behavior. An S-O-R framework is used as an overall basis in order to outline the effects investigated in this paper.
Undersökning av vindlaster på en parabolantenn
Vi fick i uppdrag av Swepart Transmission AB att med lämpliga metoder beräkna vindlaster på en godtycklig parabolantenn samt att konstruera en växellåda för att positionera den. Vi insåg i ett tidigt skede att vi var tvungna att ta fram vindlastfaktorerna laborativt. Och på grund av den begränsade tiden var vi tvungna att fokusera endast på vindlasterna på en parabolform.Först uppskattade vi de maximala vindlaster som kunde uppkomma för att kunna dimensionera vår mätram. Sedan beräknade vi lastcellerna och konstruerade erforderlig elektronik. För att simulera vind monterades parabolen och dess mätram på ett fordon, mätningarna utfördes sedan på Uråsa flygfält.
Outbreaks of African swine fever in domestic pigs in Gulu district, Uganda
The demand for animal products has increased in the last decades, especially for poultry and pork. Pork production has increased drastically globally, and also in Uganda. Thirty-one percent of Uganda´s population lives in poverty. Pig production is believed to play a crucial role in poverty alleviation, because of the ability to convert low quality feed into high quality protein together with high reproductive potential.
African swine fever (ASF) is a lethal disease of domestic pigs often characterized by haemorrhagic fever and with mortality rates up to 100%. The disease is endemic in most sub-Saharan countries and since 2007 in the Russian Federation and Caucasus area.

Småskalig livsmedelsförsörjning av mjölk :
During the last year?s Swedish agriculture have had difficult times, with decreasing
prices and at the same time increasing production costs, which has led to bad
profitability and faith in the future.
The dairies in Sweden have also had a rough time and there have been large
rationalizations during the years. In the beginning of the 20th century there were almost
1700 diaries in the Swedish countryside. There has been a large technical development
during the 20th century resulting in a decrease in diaries to only 46 in the whole country
today. They are owned by 15 diary companies, of which 7 large and dominate on the
market and the rest are small-scale companies.
With this development the confidence and feeling for the diary companies also has
decreased.
