Today a lot of goods is transported on wood pallets because it?s practical and enabels a fast way to load cargo. The drawbacks with pallets are that they weight a lot, are big and are relatively expensive. Therefore IKEA has developed plastic lists that can replace the europallet in some applications. In this examwork an automatic handling equipment for plastic lists are design from a requirement specification to a finished machine.
Referensvåtmarker för uppföljning av växtnäringsretention i anlagda våtmarker
One of the environmental problems today in seas, lakes and streams is eutrophication. This is often caused by nutrients such as phosphorus (P) and nitrogen (N) that leak from agricultural areas. A measure to partly prevent the nutrient discharge is to construct or restore wetlands.In order to control the efficiency of nutrient reduction of existing wetlands in the county, the administrative board in Västra Götaland wants to find different criterias for reference wetlands. These reference wetlands should represent other wetlands and be used in future evaluations of reduction of nutrients and design of constructed wetlands. According to the administrative board in Västra Götaland the reference wetlands should have a catchment area of about 50 hectare consisting of at least 70 % arable land, to represent wetlands created to remove nutrients.
Interaktion med närstående till kritiskt sjuka patienter. : Vilka svårigheter finns?
Background:When the patient is critically ill the family is in a vulnerable position. The nurse's role is to support and help the family to find meaning in the difficult situation and to provide realistic hope. Balancing between the patient's and the family's needs is difficult. Knowledge about how nurses experience difficulties in the interaction with family is required in order to grant good care too critically ill patients and their family-members.Aim:To describe nurses' perceived difficulties in the interaction with family-members of critically ill patients.Method:The study is a qualitative literature-based study based on qualitative research. Results: The analysis resulted in four main themes; difficult disunion, environmental constraints, interpersonal difficulties and communicative difficulties.
Hej Litteraturen! : En studie av ett läromedel i litteraturhistoria ur ett genusperspektiv
The purpose of this study is to examine, from a gender perspective, Utbildningsradions TV-program Hej Litteraturen! in the light of feminist literature studies conducted during the last twenty years. I want to examine if the feminist literature studies have had any impact on contemporary teaching material regarding the question of how much space in time is given to men versus women and which female authors are included in the literary canon. Hej Litteraturen! is a TV program produced in 2010 intended for high school teaching of literature history. By conducting a content analysis in which I divide the study in a quantitative and a qualitative component, I have investigated how much space and time is given to female writers and how they are presented. My analysis draws on use Yvonne Hirdman?s theory of the gender system. The result shows that the female authors get 37 percent of the total reference space and 42 percent of the time-space. The program has sought to describe male and female authors equally and gives them weight and relevance to the sections in a similar manner. In conclusion, Hej Litteraturen! is a tutorial which embraces parts of the criticisms that have existed in historical literature review papers in general and literary history textbooks in particular. Hej Litteraturen! has worked on gender aspects of the program and by picking up contemporary authors as reference points for literary history in the present, the program contributes not only not only in renewing the literary canon, but also in balancing out the dominance of male writers in the history of literature..
Belastningar i bettet och dess korrelation till hästens rörelsemönster vid körning på rakt spår :
The use of a bit in the mouth of a horse is being increasingly questioned with respect to its actual function, and is sometimes judged an obsolete instrument of control with potential to injure the horse.
The objective of the research presented herein was twofold; firstly, to investigate the actual pressure load in the mouth of the horse with regard to oral health issues, and, secondly, to investigate whether this could be a viable method to objectively measure strength exerted by a rider/driver to the mouth of the horse especially with regard to training regimes.
From the results, it is evident that these newly developed sensors have a future in equine research, although they are still under development. They can be useful both as a pedagogic teaching instrument, providing instructor and pupil with instantaneous, objective feedback on the contact between hand and mouth, as well as an aid in measuring pressure loads from our common bits.

Dubbla karriärer : Elitidrottsstudenters uppfattningar om kombinationen elitidrott och akademiska studier
Retiring from elite sport can be a difficult and disruptive process for an elite athlete. To improve the quality of the transition after retirement, elite athletes are recommended to have dual careers which mean they combine their sport with education to be prepared for a new career when they retire from elite sport. To help elite student-athletes with this combination, universities and sport organizations provide different kind of support. This study was conducted and aimed to investigate elite athletes? perceptions of support offered by a university in Sweden and the elite athletes? perceptions of combining top level sport and academic studies.
Secondhandapparnas dilemma: milj?hj?ltar eller konsumtionsdrivare. Analys av secondhandappars inverkan p? unga vuxna kvinnors konsumtion
This thesis examines how marketing by secondhand apps affects young adult women's consumption habits, investigating whether these platforms promote or counteract overconsumption. While the secondhand market is considered more sustainable than buying new, these apps may still encourage overconsumption. The study focuses on the marketing strategies of three major secondhand apps in Sweden: Tradera, Sellpy, and Vinted, analyzing their impact on consumer behavior using the AIDA model (Attention, Interest, Desire, Action).
Based on qualitative interviews with eleven women aged 20-27 and the authors observations of the apps marketing activities, the study finds that secondhand apps often emphasize environmental benefits and makes secondhand shopping accessible and appealing. However, the marketing tactics used by these apps, including frequent push notifications, targeted advertisements, and influencer collaborations, may lead to increased consumption.
Overconsumption causes significant environmental damage, and while the secondhand market can mitigate these effects by extending the lifecycle of items, the emphasis on convenience end environmental benefits can inadvertently encourage more consumption. The study concludes that secondhand apps play a complex role in consumer behavior, balancing the potential for sustainability with the risk of promoting overconsumption.
Möjligheter och hinder för aggregerad förbrukningsflexibilitet som en produkt på reglerkraftmarknaden
Electricity production from renewable energy resources such as wind energy and photovoltaics is variable. Integration of these intermittent resources into the electricity system leads to new challenges in how to manage imbalance between supply and demand on the grid.One way to meet these challenges is to develop so-called smart grid solutions. One idea, called demand response, is to adjust the amount or timing of energy consumption, e.g. by control of household appliances, to provide flexibility that could be used to balance the grid. In aggregate, when applied to many units across the system, large volumes of energy could be made available when needed and this grid flexibility can be used as a product on the electricity regulation market.Despite the potential benefits, the number of demand response bids is currently low.
Överföring av och beräkning med timmätta värden ? från MT2000 till Xpower
New technology makes it possible to remotely measure all consumers in a power network onan hourly basis and store the values in a database.This thesis work describes the conversion process between automatic meter reading systemMActor and calculation software Xpower.Then the possible differences between calculations of power networks using load curves incombination with a yearly estimate of consumption and calculations using hourly measuredvalues is examined.The result of the comparison shows that, for the power network under inspection, nosignificant difference could be noticed. This does not mean that calculations using hourlymeasured values would be unnecessary. I believe that in a near future calculations using hourmeasurements will be the primary choice for many power companies to whom technology isavailable.Also some basic calculations of fundamental power network parameters, such as power factorand loses, are presented using hourly measured distribution transformers in combinations withits hourly measured loads.The report is written in Swedish.

The aim of this study was to examine how the interviewed teachers in one school observe their view of gender and equality regarding the educational system. Accordingly, I would like to present my intention with this study, also be to analyze how the interviewed teachers way of working with matters of gender and equality, carry out as a portrait of their values considering the distribution in terms of gender. The research questions are the following: What is the teachers view on the concepts of equality and gender in school?How do different teachers talk about their way of working in relation to gender and equality in school?How is boys and girls images presented in the teachers descriptions in their discussion about gender and equality?This study is based on a fundamental qualitative method, where a handful number of teacher?s from one school were interviewed in order to obtain information and data for the examination. The interviews were analyzed and discussed in association to earlier research in aspiration to study different writer?s theories about the conception of gender and equality.
Translokation av större vattensalamander : -bevarandestrategi eller riskåtgärd?
This study evaluates the retention of nitrogen and phosphorus in four newly constructed wetlands in the municipality of Falkenberg, Sweden. The four wetlands have been selected because they have been specifically constructed with the aim to reduce nitrogen and phosphorus in farming areas. The process of selecting the specific wetlands has been done in collaboration with the county administration in Halland. Through field studies in collaboration with the landowners where the wetlands are sited, the areas that provide the wetlands with water were determined. The size of these drainage areas were determined in a GIS computer program. The type of land use within the drainage areas was also determined.

Ordfrekvens och repetition i läromedlet Lieber Deutsch : En analys av den språkdidaktiska förankringen i ett svenskt läromedel i tyska
The aim of this study is to examine the word acquisition, focusing on the nouns and word exercises, in two Swedish textbooks for German in the upper secondary school. The chosen method for investigating the nouns was corpus analysis. The noun frequency and distribution in the textbooks were analysed and discussed in relation to research in second language acquisition. The Involvement Load Hypothesis by Batia Laufer and Jan Hulstijn was used to examine the exercises in the textbooks. The study showed that most nouns only occurred once in the textbooks, but the most frequent nouns were well spread in the textbooks.
Beräkningsmall för vindlast enligt Eurokod baserad på väggar och olika taktyper
Detta examensarbete har genomförts på begäran av byggnadstekniska byrån i Uppsala. Företaget behöver en ny beräkningsmall med vindlastberäkning för väggar och olika taktyper enligt Eurokod.I dagsläget använder företaget en beräkningsmall som är baserad på gamla normer enligt BKR. Dessa normer kan dock inte användas längre enligt nya bestämmelser inom branschen. Enligt de nya bestämmelserna bör dessa vindlastberäkningar genomföras med hänsyn till Eurokod i framtiden.För att kunna beräkna vindlasten enligt Eurokod och effektivisera beräkningsgången har man utvecklat en beräkningsmall baserad på Eurokod. Alla nödvändiga parameterar enligt standarder har använts i beräkningsmallen och användaren tillåts genomföra en snabb och enkel inmatning av projektmått för att på ett automatiserat sätt genomföra belastningsanalysen.
Föroreningar orsakade av stenar inblandade i barrmassaved
Holmen Skog AB is an important supplier of conifer pulpwood to the Iggesund Paperboard mill. After logging and transport to the landing by a forwarder, the wood is loaded on trucks for further transport, often by using separate loaders. During this handling process considerable amounts of stone material is sometimes mixed into the pulpwood and this causes problems for the industry. The aim of this study is to identify which part of the chain from forest to pulpmill, that contributes the most to this contamination. Sizes and total volumes of the contaminating stones were also investigated.
