Deltid och kön: En undersökning av deltidsarbetets utveckling under åren 1987-2005

This paper aims at assessing the relationship between female and male part-time employment and the business cycle in Sweden during the years 1987?2005 using quarterly time-series data and two alternative indicators of the business cycle. It further aims at determining whether the share of women working part-time has changed over time. Key results include that the relationship between the business cycle and female part-time employment is found to be significant and countercyclical. No significant effect is however found for men.

Cykeltidsoptimering av sjuaxligt robotsystem

This master thesis studies how much the Cycle time, i.e. the time it takes for an industrial robot to perform a given task, can be reduced if an extra degree of freedom (DOF) is added to the robot system. The extra DOF consists of a linear track, which is supposed to be used in an optimal way. The problem has been studied using simulations in the robot simulation tool RobotStudio. To be able to run an optimization in Matlab, with the RobotStudio simulation Cycle time as the object function, communication between Matlab and RobotStudio has been set up with an interface written in Visual Basic.

Omloppstid för returenheter

Cycle time has a direct influence on number of returnable crates needed and therefore a crucial parameter for cost structure and pricing of the user fec in the pool system.For providing the growing market, number of crates has to increase as well as the utilization of existing crates. To accomplish this aim, Cycle time for the whole supply chain has to be fully unravelled and understand.The purpose is to map Cycle time and stock movements, to see how, where and when crates are being used in the supply chain. The goal is to make a method of Cycle time calculation, together with suggestions of improving the pool system and decrease Cycle time.The study has been a combination of qualitative and quantitative research and comprises the three biggest wholesalers in Sweden; ICA, Coop and Axfood. Furthermore have 65 grocery shops, connected to the wholesalers, been investigated and mapped.The study has come to a conclusion that Cycle time for an average returnable crate is 19 days. The full-size and half-size crates have a bit longer Cycle time, 21-22 days, while Dual Height-crates and shallow haif-size crates have 17-18 days.

The role of cell cycle control mechanisms in regulated and sustained cell proliferation

The cell cycle is the time a cell spends between two cell divisions. The cell cycle includes several parallel processes, all of which must be completed before a cell is mature for dividing. In the first place, all subcomponents (RNA, protein and membrane lipids) need to double in quantity and this occurs continuously through the cell cycle. Furthermore, the genome and some chromosomal proteins must double and this take place during a limited interval in the middle of the cell cycle (S-phase). On either side of the S-phase are two "gaps" which is called G1 and G2. When the cell has passed a point in the G-phase they are irreversibly programmed to progress through the remaining of the cell cycle and will undergo the next cell division. When a cell have passed a point in the G1 phase, approximately four hours after mitosis, a normal cell is in a state of indecision.

Energieffektiv torkning av kläder : en studie av torktumlare med varm- respektive kallvattenanslutning

Tumble dryers and drying cabinets have to a large extent replaced the traditional way of drying clothes outdoors. They are faster, more convenient, require less space and can be operated regardless of weather conditions. This replacement has significantly increased residential energy consumption, due to the fact that tumbles dryers consume large amounts of electrical energy. In the USA 9 % of the households electric energy is consumed when drying clothes. Over 4 million tumble dryers are sold in Europe each year and 20 % of the residential electricity consumption in Sweden is used drying and washing clothes.

E-arkivering hos stadsarkiv : Mellanarkivslösning i sitt sammanhang

Digital preservation is a relatively new subject to Swedish archives. Alhough computers have been used for a long time, preservation has been made on paper and stored on shelves. These days a lot of cities in Sweden have investigated how to best secure the digital information for the future through electronic archiving, e-archives. One option is to hand in the information as soon as possible, but to let the producer keep the information ownership yet some time. The idea is to let the producers of the information answer questions and hand out material, since they are more competent on their field.

En vidareutveckling av förvaltningsmodellen vid systemförvaltningsprocessen

Detta arbete behandlar problemområdet systemförvaltning och är en vidareutveckling av förvaltningsmodellen vid systemförvaltningsprocessen. Vid systemförvaltningsarbetet finns det olika förvaltningsmodeller som kan vara ett stöd vid taktisk och operativ styrning samt administrativ kontroll.Systemförvaltningsmodellen består generellt av sju olika rekommenderade delmodeller där bland annat systemförvaltningsprocessen ingår. Modeller för systemförvaltningsprocessen bör förenkla, effektivisera och ge stöd när systemförfrågningar samt systemkrav inkommer från verksamhetsledningen eller systemanvändaren. Undersökningen i detta examensarbete fokuserar på en vidareutveckling av modellen Application Maintenace Cycle (AM/Cycle) som utvecklats av Peder Brandt.Vidareutvecklingen i detta arbete resulterar i en modell för systemförvaltningsprocessen, vilken benämns Application Maintenace Schedule Cycle (AMS/Cycle). Litteraturstudier och intervjuer har påvisat vissa svagheter med modellen AM/Cycle, vilket tagits i beaktande vid vidareutvecklingen av AMS/Cycle.

Identifikation av produktionsstörningar och obalanser vid tillverkning av golvskenor

Our report procedure identification of instability and disturbance in an automatic manufacturing line of processing and assembling of chair sliding rails at Sapas manufacturing department in Vetlanda.To obtain a stabile ground we have mapped the material flow to receive a comprehensive view and to visualise connections.We have examined Cycle times at different stations in purpose to identificate bottlenecks. The result of our examination showed that the bottleneck of the line was the brush station. This leads to that the expected bottlenecks identificated by Sapa gets a delay time and by that a longer Cycle time.Interruptions has a clear negative influence at the line performance so we have also assemble data through the operators report list and compiled these in order to find out the interruptions effect on the line. The outcome during our assembled period was that the reported interruptions corresponded about 30 percent of the total available production time. This has a clear negative effect on the line productivity and efficiency as we have calculated in order to get the present status..

Lönsamhet i svenska banker - En tidsserieanalys av de svenska storbankernas lönsamhet och risktagande

This study aims to scrutinize the four major banks in Sweden on how their profit havedeveloped over a time span of 15 years, whether stricter regulations have had anyimpact on financial key ratios and if there is any correlation between the banksprofitability and their risk taking. The period covered is the years 2000-2014. Thefigures are annually and the four major banks are; Handelsbanken, Nordea,Skandiviska Enskilda Banken (SEB) and Swedbank.The findings are that financial key ratios that include net income are pro-cycle whereSwedbank has the biggest volatility over the period and that the three other banks areless, but clear pro-cycle. There are also indications that stricter rules have madeimpact on the volatility of the profitability even though the period covered is notenough to ensure this claim. Nordea has had the lowest and most stable capital ratiothroughout the period and the other three banks lowered their debt-to-equity ratiosignificantly after the financial crisis in 2008.

Glucose markers in healthy and diabetic bitches in different stages of the oestral cycle

The female dog has a unique reproductive endocrinology, with high levels of progesterone throughout the 70-day long luteal phase. In this project, markers of glucose metabolism were studied and compared from the aspects of breed group and time in oestral cycle. The parameters studied were: glucose, insulin, progesterone, fructosamine and the newly introduced analysis of HbA1c. Hba1c was also further evaluated and discussed as a diagnostic tool in canine medicine.No differences in terms of glucose markers were found between a group of purebreed dogs of various breeds compared to a group of dogs with high risk of dioestrus diabetes, namely the Norwegian and Swedish elkhounds.No differences were found between the two sample occasions, anoestrus and dioestrus, concluding that there is no need for relating test results to the time of the oestrous cycle in middle-aged intact female dogs.There were statistically significant higher values of all glucose markers in diabetic dogs than in non-diabetic dogs. When it came to HbA1c, however, there was a larger overlap between the two groups, compared to fructosamine.

Från Bomull till Byxor Livscykel Inventering och Ansvarsfullt Företagande En MFS i Södra Indien

A growing number of companies realise that to achieve their environmental goals and satisfy stakeholder expectations, they need to look beyond their own facilities and to involve their suppliers in environmental initiatives. A life cycle approach means that the production system should be optimised as whole, across national boarders and individual organisations taking part all the way from extraction to disposal. This study is a Life Cycle Inventory of resources used when producing a piece of cotton garment and the method is based on the standardisation series of ISO 14040-43. The area of study, Tamil Nadu the most southern state of India, accounts for more than 90% of India?s knitwear exports to Western Europe.

Construction and maintenance of forest truck roads are a necessary element of industrial forestry. Payment for contracting services in this context can be done according to a number of payment models. This study will focus on the methods and consequences associated with a change of Holmen Skog?s payment model from per hour to per metric ton for ballast hauling. The aim of this study is to improve the economic efficiency of Holmen Skog?s ballast hauling in construction and maintenance of forest truck roads. This is done by formulating and evaluating a proposal for a payment model based on crowns per ton.

Barns tolkning av en modell för vattnets kretslopp : -förståelse och tillämpning

AbstractThe purpose of this study is to find out how pupils give expression of a water cycle model and if the model causes any misunderstanding. Two problems constitute the starting point for this investigation. The first question is: how do the pupils explain the water cycle with the help of the jar model (can of glass). The other question is: can the children see any similarities between the can of glass and our earth. Qualitative semi structured interviews with seven pupils in the ages of 8-9 have been used to show the pupils? own thoughts and how they express them.
