Solenergi i Norrra Djurgårdsstaden
This report will examine various solar energy technologies in order to decide if they could be applied in the Royal Seaport. The Royal Seaport is a Swedish urban district under development in Stockholm, with the goal of becoming a sustainable district. Two main techniques, solar collectors and solar cells, including sub-categories, are addressed in this report. Another sub-category, a hybrid system, will also be mentioned. The main difference between solar collectors and solar cells is the type of energy produced by the system.
Värdeflödesanalys med fokus på förbättring av ledtid och leveransprecision
Detta examensarbete har utförts inom borrstålstillverkningen på Sandvik Materials Technology (SMT) i Sandviken. Borrstål är en viktig produkt för SMT, vars efterfrågan har ökat stadigt under en lång tid och även i framtiden spås öka. SMT har länge strävat efter att höja leveransprecisionen på det borrstål som levereras, då leveransprecisionsmålet som i dagsläget ligger på 95 procent inte har uppnåtts på länge. SMT har även uttryckt önskemål om en kortare ledtid för tillverkningen av borrstål från råvara till kund, vilken historiskt sett uppskattats till åtta veckor.Syftet med examensarbetet är att, genom utförandet av en värdeflödesanalys, identifiera förbättringsförslag som kan effektivisera produktions- och planeringsprocessen vid ett tillverkande företag.De metoder som har använts för att utföra examensarbetet är litteraturstudier, observationer samt intervjuer. Utöver detta har prognos-, beställnings- och leveransdata samlats in med hjälp av de system som används på SMT samt även information kring cykeltider för de ingående processerna i borrstålsflödet.De mest tongivande teorierna som examensarbetet utgått ifrån och som författarna genomgående haft i åtanke är Lean Production, värdeflödesanalys, lagerstyrningsprinciper, linjebalansering och SMED.Genomförd kartläggning av nuläge och analys visar att kundernas prognos- och beställningsmönster inte stämmer överens av olika orsaker samt att balansen i borrstålsflödet inte är optimal.
Biologin hos svenska Lilioceris arter och åtgärder för att begränsa deras skadeverkningar :
Summary
The leaf beetles, Lilioceris lilii and L. merdigera have existed in Asia, Europe and in North Africa for a long time, but have become much more abundant the last twenty-five years. Even North America has been affected during the last years.
The purpose of this investigation of Lilioceris species in Sweden, is to give advice to gardeners, which type of control measures is the most effective in order to restrict their damage to lilies.
Lilioceris species overwinter normally as pupae in the soil under the host or close by.
Literature and contact with advisors have described the life cycle and spreading of Lilioceris. Under favourable conditions these leaf beetles have two generations/year in the south of Sweden. Both the adults and the larva eat the foliage, and by strong attacks even flowers can be eaten and only the stem is remaining.
My own observations include different treatments of both lily foliage and of the leaf beetle.
Oxygen Health : Inlösning av syre i vatten
The project has been provided by Zenit design group and the goal for this project was tomanufacture and perform tests of a prototype that supersaturates water in a continuous flow ofwater. The project has involved finding and sorting out relevant data in scientific papers, books,communication with foreign manufactures and other platforms for information.The project has resulted in manufacturing of a test rig and an oxygen infuser based onmembrane technology. The test rigs purpose was to perform tests on oxygen infusers fordifferent comparison test and performance benchmarks in a in a laboratory provided by Zenit.The project led to satisfying results using the oxygen infuser manufactured by the authors withcomparable levels of saturation to the reference infuser.The theory behind this project is based on medical research, belonging terms will be explainedbut the authors have chosen to delimit the project from the medical area. The reason for this islack of knowledge in this area and its irrelevance to the mechanical engineering education insuch..

Preporsition for bachelor thesis project, working from the inside and out. Emphasising spatial quality and experience, More or less ignoring form and program. I?ve had issues with these aspects in earlier project, the form or the program takes alot of place in the project. I haven?t tried this approach before, it?s an attractive thought to allow the project take a form of it?s own, enclosing those spaces i create.The initial concept was to place the pools on the ground (not digging them into the ground) making them volumes that divide and define spaces.
Vandring av vårlekande fisk och jämförelse av fångst mellan ryssja och strömöversiktsnät i Hammerstaån, Stockholms län
During the last two hundred years many wetlands and streams in Sweden have been lowered to provide land for agriculture and forestry. Some of the coastal wetlands and streams probably served as spawning sites for certain species of fish in the Baltic Sea, but the present situation is not well known. As standardized methods to monitor fish in running waters are carried out during late summer or autumn, there is a need for methods to sample spring-spawning fish in these streams.The aim of this study was to survey the lower kilometer stretch of Hammerstaån in Stockholm, to investigate the extent to which the stream is used by spring-spawning fish. Furthermore, the study aims to evaluate a new type of survey fishing gill net called strömöversiktsnät (SÖN). This was done by comparing the catch of fish by SÖN with that of fyke nets.
Framtagning av analysmetodik för uppslutning av kemiska produkter
The purpose of this thesis was to develop and optimize a method of analysis for combustion of organic chemical products, followed by an ion chromatographic quantitative analysis. This was to be achieved with the decomposition equipment IKA AOD 1. The aim was to receive a precise and repeatable method that would be able to be applied to the process of qualification and technical marking of chemical products at the company, OKG AB in Oskarshamn. A complete instruction for the decomposition equipment and the method of analysis was written. A number of parameters were chosen from the general method of the combustion equipment, which then was tested parallel with a simultaneous development of an appropriate ion chromatographic method.
Grovfodermajs : från odling till utfodring av växande nötkreatur
The use of forage maize has increased over the last years. The aim of this litterateur review was to summarize a part of the research that has been conducted on forage maize for growing cattle, including cultivation and conservation of the maize. The forage maize is planted in April or the beginning of May when the temperature in the soil is between 6 and 10°C. Maize needs high temperatures and much water. Maize is harvested in the autumn when the dry matter (DM) is more then 30% or the plants have been exposed to the first frost in the autumn.
Orsaker till kolik hos häst
The aim of this work was to investigate possible risk factors for colic in horses, and to describe what horse owners can do to prevent this condition.
The gastrointestinal system of the horse is constructed for continuous high fibre consumption for a period up to eighteen hours a day. Under those conditions, the continuous flow of digesta stimulates gut motility so that the intestines move constantly. When the diet is changed rapidly and the horse is being fed high rations of concentrates each day, the risk of getting colic is higher compared to when consuming less concentrates and giving the horse a stable diet.
Lack or absence of access to water and restricted allowance to move freely every day increases the risk of colic. Changed management practices and decreased activity contributes to increased risks, as well as other critical risk factors such as breed, season and age combined with rapidly changed management.
More knowledge and education is required of the horse owners about feed requirements in the horse, management routines and rapidly changed activity..

This was followed by brainstorming, evaluation and completion.The result was a concept for de present time and one concept for the future.The present concept is intended to be built immediately. This is an adjustable bench with sliding bearings to facilitate the work. The actual cleaning is done with a high pressure washer that uses hot water.
Värdeflödesanalys av 9000E - serien diskbänkblandare hos FM
Mattsson AB
FM Mattsson är norra Europas ledande tillverkar av vattenarmaturer och lanserade i början av 2008 en ny produktserie, 9000E, där E står för ECOSAFE. Vid framtagningen av denna blandarserie har man designat produkten med material utifrån en miljösynpunkt, därav namnet ECOSAFE. Man har vid FMM upptäckt att ledtiden för Köksblandaren i 9000E-serien är för lång för att kunna möta ett ökande kundbehov och ökad konkurens. Man vill därför genomföra en värdeflödesanalys för köksblandarna för att undersöka varför ledtiden blir så lång och om den går att korta ner för att få en ökad produktionstakt. Huvudmålet med projektet har varit att ta fram ett förslag som ger en reducerad ledtid med >30% samt ge rekommendationer för hur detta ska genomföras.
Att våga förnya för att förmedla : Förnyandet av den moderna sakrala konsten sett ur tre konstverks uppkomst tagna från konstprojektet "Kyrkorummet"
In this essay the renewal of the modern sacred art has been examined through the creation of three works of art from the art project ?Kyrkorummet?. The aim has been to show that renewal of the modern sacred art is best accomplished by the combination of the artist history and Bible knowledge and the open mindness of the beholder towards the new and creative, in order to communicate the gospel in modern time.The large extend of the art project demanded a selection of the art works. Therefore, three were chosen and they show the last supper and the baptism in a renewal way including both symbolism and creativity. To complete and facilitate the analyses, a theme, light and water, have been used as well as relevant theories in art history with Kandinsky as main art critic.Through the art project and it?s teaching, history in combination with present time through visits in different and modern churches, thoughts have been stimulated and the result has been new works of art that speaks of our time.

Rehabiliteringsmetoder för häst och hund :
Today, many veterinary hospitals offer rehabilitation as a service. We think that this is an interesting subject and therefore we want to find out what rehabilitation methods that are available in Sweden for dogs and horses. We want to give animal nurses and other persons who have animals as an occupation an survey that shortly describes how the methods are performed, what physical effect they have in the body and to give examples in what conditions they are used. To find out what rehabilitation methods that are available we sent out two different questionnaires, one to hospitals/clinics for small animals and one to hospitals/clinics for horses and other companies that works with rehabilitation of horses. The information about the methods described in our project we have found in literature and on the Internet.
