En ny utvärderingsmetod för reaktionskrafter från mutterdragare baserad på upplevd belastning

Reaktionskrafter från monteringsverktyg är troligen en bidragande orsak till mångabelastningsskador i tillverkningsindustrin och monteringsarbete ligger också i topp istatistiken över arbetssjukdomar i Sverige.Idag används i stor utsträckning avancerat styrda verktyg, som kan programmeras så att dekänns bekväma, men det finns ingen utvärderingsmetod för reaktionsmoment som premierardessa funktioner. Dessutom tar dagens utvärderingsmetoder hänsyn till att människor är olikastarka i olika arbetsställningar.En utvärderingsmetods främsta syfte är att hjälpa till vid val av verktyg och vid bedömningom reaktionskraften kan tas upp för hand eller om mothåll bör användas. Tas inte operatörensstyrka beroende på arbetsställning med blir denna bedömning i många fall felaktig.Syftet med det här arbetet är att ta fram en bättre bedömningsmodell för reaktionsmomentfrån monteringsverktyg. Några krav som sätts på den förbättrade metoden är att den ska varaenkel att använda, mätningar ska inte behöva göras på verktyget och den ska ta hänsyn tillvariation i styrka beroende arbetsställning.En grupp om sju testpersoner sattes samman och de utvärderade reaktionsmomentet från envinkelmutterdragare i tre olika positioner. I varje position testades 6 olika typer avreaktionsmoment.

RFID på Kvarntuna stadsbibliotek : Teknikskifte som möjlighet till förändrat arbetssätt?

This two years master's thesis in Library and Information science, examines how the implementation of new technical equipment can affect how staff in public libraries organize their work and activities in the library. One Swedish public library in specific is the subject of research in this thesis, which has been anonymized as Kvarntuna city library. The study takes place in the beginning of the implementation of RFID-technology in the library. RFID, which stands for Radio Frequency Identification, is supposed to make the handling with different types of media in the library more efficient and in connection with the implementation one wants to reorganize work and activities in the library to make it even more efficient and also create a modern library.The thesis' method is qualitative interviews with six members of the staff. The theoretical framework of the thesis is a sociocultural perspective, especially inspiered by Roger Säljö, a Swedish professor in pedagogical psychology.

The behaviour of foals before and after weaning in group

Weaning is a standard procedure at most studs, and the methods of weaning varies greatly. The method used at the stud in this particular study is supposed to decrease stress. The purpose of the study was to compare the behaviour of foals in group before and after stepwise removal of their mares. Standardbred foals with their mothers were kept in three different groups at pasture (12, 11 and 11 foals, respectively, mixed sexes). They had free access to silage and the foals were fed concentrate in a creep-feeding area. By the time the foals were 5 months old, the mares were stepwise removed from the pasture.

Tidsstudier i kalvuppfödning :

Swedish agriculture stands in front of big changes the whole time. As a milking producer you have to adapt and develop the company to these changes and find the best solution. This potential is easy to find if you compare your company with other similar companies. Labour cost is the biggest cost in milking production after the cost for food. Today it is rather easy to measure how many hours per cow different system of cow houses needs, but we do not know so much about how many hours it takes to breed a calf. To learn more about the labour time with the calves during the first time after the calf was born, I made time studies on five different farms with calf hutches, automatic milk system, large calf boxes, and smaller calf boxes with teat buckets.

Tredjepartslogistik ur ett sakrättsligt perspektiv

It has become fairly common for a company to outsource one or several of its logistic activities to a party separate from the business of the company itself. Since the original agreement usually involves two parties, the seller and the buyer, the logistics company is called the third party. The relationship between the outsourcing company and the third party varies in form and in depth but can sometimes be very close, almost to be considered a joint venture. When the co-operation between the two parties includes more than just one separate logistic service and the third party adapts its business to a certain extent to his principals needs, it constitutes third party logistics. If the logistics company, or a party employed by it, becomes insolvent when having the entrusted goods in his possession questions may arise concerning the right to the property.

"Varför blev det så här?" : om utemiljön på Herrgården från 60-talet och framåt

The residential yard at Kvarteret Landsfiskalen 1, in the area Herrgården in Rosengård, Malmö was built in 1971 and has since then been reconstructed twice, in 1984 and 2008. The yard is found in an area which was built during the years 1965 ? 1974, a period in which the swedish goverment approved a decision to build one million homes, and much of the events in this particular yard is also typical for the process in many other areas built during the same period.At the original construction the design of the yard was entirely incused by the pressure in time and finance, one was under at that time, in order to over- come the housing shortage. The design it has nevertheless been given, reflects the esthetic ideals of that time well.The building of the area was barely finished when the swedish authori- ties started handing out grants in order to support the rearmament of the outdoor environment in the areas built during the so called ?million program?.

Kompostering av köksavfall och användning av kompost i köksträdgård i Chazuta, Peru : jordförbättring och/eller lösning på ett avfallsproblem?

All over the world the waste from human society is causing problems. In developing countries, large cities are polluted through huge amounts of wastes and people are forced to live very close to open deposits. Lima, capital of Peru, is no exception. The countryside in Peru has also a great challenge to face concerning the waste issue. Children and adults suffer from infectious diseases and contamination of the nature occurs as well. One solution to handle organic waste is to compost, which means a controlled decomposition of organic waste under aerobic conditions at certain temperatures.

Hur uppfattas pcSKOG AB och pcSKOG-gård av privata skogsägare? : en undersökning av en programvara för privatskogsbruket

pcSKOG-gård is a computerised manager plan for private forest owners, developed by the pcSKOG AB. The program is based on forest stand data, joined with a map of the forest and GIS-applications. The purpose is to offer a program for private forest owners managing the forest and with the possibility of updating the actual status of the forest. The company pcSKOG AB is the leading producer of programs for forest management and has developed the program since 1997. The program is currently the most common program used by private forest owners in Sweden. The aim of this thesis, leading to MSc in forestry, is to investigate the purpose of the private forest owners when purchasing the pcSKOG-gård. The thesis also studies how private forest owners use the program, what they use it for and how the private forest owners state that the program has achieved to fulfil their expectations. The thesis is also a market research concerning the knowledge and attitudes the private forest owners have about the program and associated services. The study material has been collected during two phases.

Med elevens ögon: resan från grundskola till särskola

Today in Sweden the concept of the greyzone students that stands between the nine-year compulsory school and special school for mentally retarded children is recognised in different studies and reports. It is not obvious for this group of students to decide which category best can comply with their needs. Should they go in nine-year compulsory school or special school for mentally retarded children? In the last years there have been alarming rapports about how the share of students in special school increases. A study shows that the greyzone students are a group that distinctly is on the increase in the special school.

Att kommunicera idéer och visualisera information i 3D :

In order to respond to a more complex community planning with increased cooperation and public participation, a common language and a common model to be used as a base for the communication process is needed. The thesis behind this dissertation for a master's degree is that a virtual 3D planning portal would respond to this need. Why and how are explained and described through studies of communication- and perception theory as well as technology and recent research. The introduction concludes that a broad participation and a transparence towards underlying information are important foundations for the coming work with the model. The first four chapters of the theory part show the benefits of using natural signs in our mixed cultural society, instead of the more arbitrary symbols. Using visual landscapes for storing information is motivated by the flexibility of our visual memory and its ability to understand complex connections.

Aspects on cow traffic and management on farms with automatic milking

This thesis consists of four case studies. The objective is to find out how to get a well functioning cow traffic in an automatic milking system. Different technical and building solutions are analysed and some adjustments are proposed for the DeLaval herd management software. Case study 1: Lactation chart comparison from traditional cow traffic and Feed First? cow traffic Case study 2: Farm A - a study of the precedence passage and the cow traffic Case study 3: Farm B ? an overview of the farm and their way of working Case study 4: Key factors ? how can we judge how well a VMS farm is working? Case study 1: Lactation chart comparison from traditional cow traffic and Feed First? cow traffic In this survey data is analysed from before and after rebuilding to Feed First? cow traffic. Lactation graphs are compared between traditional cow traffic and Feed First? cow traffic.

Kommuners val av pensionsförvaltning : En studie av den kommunala pensionsredovisningen

Inledning: Svenska kommuners verksamhet betecknas som säregen. Till detta hör att kommunerna skiljer sig från den privata sektorn i avseende på målsättning och utförande. En utav de särdrag som finns inom kommunerna är deras redovisning av pensionerna som skall ske enligt blandmodellen. Ett flertal studier har lyft upp farhågor om att redovisningen enligt blandmodellen anses leda till diskretionära tolkningsutrymmen som troligtvis kommer utnyttjas av politikerna i syfte att påverka redovisningen. En del av de diskretionära åtgärder som antas vara möjliga är pensionsförvaltning av de förmånsbestämda pensionerna.Syfte: Studiens syfte är att förklara kommunernas val av förvaltning av de förmånsbestämda pensionerna.Metod: En deduktiv ansats har använts i studien för att kartlägga de olika teoretiska förhållandena mellan pensionsförvaltning och pensionsredovisning.

Fullfoder för får :

During recent years the use of TMR (total mixed rations) has increased in Swedish lamb production. For many years TMR has been used for cattle and hence the information and knowledge is vast, while the knowledge concerning sheep and TMR is more limited. The aim of this thesis is to present an overview of the scientific knowledge on the subject, and also to compile practical experience from sheep farmers using TMR. The thesis begins with a literature review where different aspects relevant to the usage of TMR are dealt with. It is concluded that there are differences between sheep and cattle that must be taken into account.

Modeller för skattning av den vertikala fördelningen av biomassan på klena träd i röjningsgallringar

I samband med nya mål för energiförbrukningen har behovet av förnyelsebara energislag ökat. Ett sätt att möta detta ökade behov i Sverige är ett ökat uttag av skogsbränsle. Denna ökning skulle till stor del kunna bestå av ökat bränsleuttag i skog med hög stamtäthet och klena träd. För att på ett mer rationellt sätt kunna göra åtgärder i skog av detta slag är det av stor vikt att på förhand kunna uppskatta hur mycket man ska ta ut och hur mycket man ska lämna kvar som näring åt kvarvarande bestånd. Syftet med detta arbete var att skapa funktioner med vilka man ska kunna skatta biomassafördelningen i vertikal ledd för klena träd. Framtagandet av funktionerna har gjorts genom regressionsanalyser. Funktionerna bygger på data från Kristina Ulvcronas avhandling Effects of Silvicultural Treatments in Young Scots pine-dominated Stands on the Potential for Early Biofuel Harvests.
