Sustainable shopping : consumer behavior in purchasing and donating secondhand clothes
Textiles are made in an unsustainable way and there is a need to find alternative ways and material to reduce the negative impacts on the environment, humans and animals. Problems like pollution, excessive water consumption and loss of soil fertility is a result of this lack of diversity. It is a necessity to find innovative alternatives in other fabrics due to the unsustainable use of cotton and polyester fibers. As in many other countries in the Western part of the world, in Sweden there is a rapid turnover and increased selling of clothes that result in increased textile waste. About 15 kilogram of textiles (net inflow) is consumed per person each year.
Kommunikation i multiagentsystem
Communication is an important part of any multi-agent system. There are different ways of communicating and they have different effects on a multi-agent system. This project describes and evaluates two different ways of communication, implicit and explicit. To compare the two methods, two experiments have been executed. The result of the experiments have been compared and discussed.
Effektiva Lagringsmetoder för Glesa Matriser
Sparse matrices are often used in numerical algorithms that solve linear equation systems. Many methods for storing sparse matrices have been proposed and implemented during the years. These methods focus primarily on minimizing the total memory consumption and the time that it takes to store a sparse matrix. This report researches the available storage methods for sparse unstructured matrices. The formats that are researched and implemented are COO, CRS and ELL.
Datorkompetens : En studie av förväntad datorkompetens vs verklig datorkompetens vid Örebro Kommun
More and more preschools are choosing to reduce the sugar consumption. The reason is, inter alia, the increase of weight in the community, but there is also research showing that sugar is harmful to children. The discussions on sugar and children are also a hot media topic.I have chosen to use a qualitative method, interviews, to gather material for the essay. I have interviewed a teacher and a cook in three different preschools, in different municipalities. I have also looked at their various nutrition policies to see how the guidelines for their work on diet and health look like.
Optimering av ultraljudssändare- och mottagare avseende räckvidd, strålningsvinkel och energiförbrukning
Embedded Systems Lab at Umeå University is currently part of a research project with the purpose to examine the behavior of dairy cows inside a barn. Each cow needs to be tracked with a precision of 50 cm, and since GPS-technique has poor functionality at indoor environments, an indoor positioning system needs to be developed.Embedded Systems Lab has already developed an indoor positioning system using IR-light and radio, but since this system demands extensive infrastructure and is rather expensive, an alternate positioning system using ultrasonic pulses and radio is being examined.In this report the range, beam angle and current consumption of ultrasonic transmitters- and receivers are investigated. Three different driver stages for the transmitter is tested, and two amplifier solutions for the receiver. The report also describes how the length of the transmitted ultrasonic pulse affects the received signal, accessibility of a ?shadowed? signal, and the effect of different sound frequency..
Frontlinjen, Persson & Madonna : En uppsats om personer som bärare av varumärken
The purpose of this essay is to analyze and understand how people in different ways can take on the role as carriers of brands and understand what part they play in today?s society. Brands are everywhere today and the competitions are becoming harder and harder for the customers? attention and consumption, which is why I am curious of how an individual in a company?s frontline or a celebrity can help the success of a brand. The essay is based on a qualitative method where six interviews have been performed.
Hur enkel- & dubbelportsturbin i kombination med två olika avgassamlare påverkar gasväxlingsprestanda på en Scania V8
The exhaust arrangement on a Scania V8 consists of one manifold at each bank connected to a twin entry turbine (8-2-2). A study in GT-Power has shown improved performance and reduced cylinder to cylinder variations using two manifolds at each bank in combination with a single entry turbine (8-4-1). This thesis work analyses the difference in performance shown in simulation and verify it by engine test.The initial work was focused on simulation in GT-Power. Investigating how exhaust manifold volume and pulses effects the turbine efficiency and the mean effective pressure during the gas exchange. To verify GT-Power simulations four engine tests with different exhaust arrangement have been made.The results from GT-Power simulation indicate that a larger exhaust volume improve the turbine efficiency.
Produktion av krukodlade örtkryddor i växthus och dess utsläpp av växthusgaser i Sverige : energianvändning och beräkning av koldioxidekvivalenter
Abstract
The global average temperature has increased by 0,74°C over the last 100 years. Most probably, the explanation is due to increasing use of fossil fuels and the agricultural expansion of land use. The new life stile of mankind leads to increasing concentrations of greenhouse gases in the atmosphere. Food consumption contributes with approximately a quarter of the total greenhouse gas emission per person and year, why it is an important task to reduce these.
The aim of this work is to quantify energy use and greenhouse gas emissions for (Swedish) herbs produced in Swedish greenhouses. The study is based on a LCA (Life Cycle Assessment) and collected data from participating companies producing herbs in pots.

Authors: Marie Andersson, Maria Gustafsson and Johanna Olsson.Tutor: Peter CaesarTitle: Don?t forget the story ? a study about internal StorytellingKeywords: Internal Storytelling, Internal marketing, Communication, Organizational culture, Internal branding, Fellowship, Motivation, Participation.Background: Something that can be problematic for managers in an organization is to find an effective way to spread information that will received by all the employees. One way to spread information and messages to the employees is by using internal Storytelling. The use of internal Storytelling aims to create an environment to build up an engaged personnel. Organizations use internal Storytelling when they want to create collective stories and frame of references among the employees within the organization, and also spread the values of the brand and information about the organization.Problem statement: How can internal marketing be affected by internal Storytelling?Method: Our study is based on a case-study of SCA Packaging Sweden AB.
Styrsystemets roll i balanseringen mellan kontroll och empowerment : En kartläggning av ett styrsystem och varför användningen leder till observerade effekter på personalen
Problem discussion: That empowerment and autonomy can lead to desirable effects on employees is clear. Previous research has found correlations between empowerment and e.g. motivation, job satisfaction, productivity, loyalty and commitment. However, a control problem arises when employees have more freedom in decision-making which could potentially lead to undesirable outcomes. It thus becomes a type of dilemma for management and managers where you have to try to balance a restrictive use of the control system (to maintain control) and an enabling use (to promote empowerment).Purpose: The purpose of this study is therefore to identify how a company can use its control system in order to achieve empowerment while maintaining acceptable levels of control.
Varför slutar markberedningsförare?
The purpose of this study is to seek answers to an ongoing problem in the forest sector; why scarifying operators quit their job. Scarification quality is crucial for successful reforestation after clear felling. It is therefore important to keep good operators working in the business.
To collect the desirable information interviews were made both with contractors who are working and operators who have stopped working with scarifying. The conclusion one can draw from this report is that the scarifying operator job needs improvement in multiple areas. The former operators are mostly dissatisfied with the stress, low wages and negative physical effects that this work brings..

Plants as rhubarb and ginseng were used in China long time ago. The Egyptians had knowledge of herbal medicine such as aloe, myrrh and henbane, 1550 BC. The father of medicine Hippocrates used a large number of herbal medicines, and had many theories on the subject.Different parts of the plant can be used to extract the active ingredients.
Förskolors inställning till och användning avstadens natur :
This master thesis is made in co-operation with the Department of Forest Management and Products at the Swedish University of Agriculture in Uppsala and the Forestry Association in Stockholm. The purpose of the Master thesis was to describe how pre-schools in Sweden use forests and green areas, and to understand how different factors can affect the use of the nature. The purpose of the interviews was to create a picture of attitudes and routines of the pre-schools, in the matter of visiting the nature. The thesis is built on interviews where fifteen pre-schools in five large cities around Sweden participated. Among these pre-schools, five of them worked with special focus on nature, while the other ten did not have any particular focus connected to their activity.
Musik och dess påverkan på motivation under ett gympass
