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.

 Hantering av personuppgifter ? en arbetsmiljöfråga?

Unhealthiness is not just a damaged back or asbestos. The fact that mental ill-health seems to increase in our society is well known. Statistics from Arbetsmiljöverket proves a fourfold increase of work-related disorders since 1997. These are primarily caused by organizational and social factors, 60% are considered caused by stress and a heavy workload. Sick leave due work related fatigue and depressions are scarily common today.

Medarbetare på den innovativa scenen : ? en studie i medarbetares syn på innovation inom kommunal verksamhet

Abstract Title:                       Grades at Primary School ? A study of local politicians' arguments in                       connection with the division into grades at Swedish primary schools.Author:                       Annie LinderUniversity of KalmarC-essay in Social StudiesAutumn 2011 The study aims to investigate local politicians' decisions since municipalities took overSwedish primary education in 1990/91. The arguments put forward in support of how stages are organised have been studied, likewise whether municipalities have acted rationally when making their decisions.Six municipalities are included in the survey. They were divided into three educational categories: lower, middle and high level schools; previous and recent schools and F9 schools with pre-schools and primary schools integrated.Minutes from politicians' and civil servants' meetings have been studied and categorised according to arguments for and against. The most common supportive arguments are about economy and organisation, others concern school premises, trends and the wish for a comprehensive compulsory school.

Vad är en bantad balansräkning?

Bakgrund: Under senare år har det blivit vanligare att företagen i tidningsartiklar och årsredovisningar talar om att de har ?bantat? sin balansräkning. Företag använder begreppet i flera olika sammanhang och för att signalera att åtgärder som är positiva för företagen genomförts. Innebörden och konsekvensen av de åtgärder som vidtagits i företagen varierar dock kraftigt. Syfte: Syftet med vår magisteruppsats är att utreda vilken innebörd begreppet ?bantade? balansräkningar har för ett antal företag inom olika branscher.

Kontinuerlig RFID-detektering för batteridrivna system

This report deals with RFID systems and how to detect nearby tags with the Mifare standard using only a microcontroller and an antenna circuit.The aim was to investigate whether there was any possibility to continuously search for a nearby tag for a system operated with batteries without compromising   the lifespan of the battery. At this time the system would take too long time to wake up and look for a tag to give a satisfactory battery lifespan, which should be done a couple of times every second.The report has two issues, namely:Is it possible to direct the microprocessor to detect and identify a nearby tag after the Mifare standard?What hardware is required for this to be possible?As the research method to provide answers to the above questions an action research was used. This approach has meant that the group worked on information retrieval, examined existing solutions, tested their own solutions and documented the results.The group examined an existing solution that can search for nearby tags with minimal energy consumption. An antenna circuit was built that was connected to the processor.

Elproduktion ur restvärme: tillämpning av ORC-teknik vid ämnessvalning

I svalhallen vid SSAB i Luleå sker det en omfattande energiförlust till omgivningen då stora mängder nyproducerat stål svalnar. I detta examensarbete studeras möjligheten att ta till vara den energin för att producera el med hjälp av Organisk Rankine Cykel (ORC) teknik. En viktig förbehållning är att inte nuvarande stålproduktion på något sätt får hindras. I arbetet undersöktes svalhallens förutsättningar och möjliga hinder för installation av en ORC. Det gjordes även en litteraturstudie över olika värmeväxlingssätt som kan appliceras på svalnande stålämnen.

EFFEKTER AV STABILITETSTRÄNING I FOTLEDEN EFTER SKADA : EN LITTERATURSTUDIE

Breast cancer is the most common tumor disease among women in Sweden. About 7000persons, having a median age of 65, are diagnosed each year with this disease. Withmammography screening, breast cancer can be detected in an early stage which improves theoverall survival (OS). 20-30 % of the breast cancer tumors are overexpressing humanepidermal growth factor receptor 2 (HER2), which is a protein that stimulates cell proliferation.Trastuzumab (Herceptin®) is a humanised monoclonal antibody that targets the HER2-proteinand prevent the signals for cell proliferation.Trastuzumab has earlier been used for treatment of metastatic breast cancer. In the year of 2007trastuzumab was approved for adjuvant treatment of patients who has been medicated withsurgery and/or radiation.The aim of this study was to investigate the effects of adjuvant treatment with trastuzumab inHER2-positive breast cancer patients.

Organisering av arbetsträning : En kvalitativ studie om handledares syn på arbetsträningens organisering och arbetet med socialt utanförskap

This study is about job training for people with psycho-social problems without income. The purpose with this sort of job training is to bring these people back to the regular labor market as well as the experience of having a job. In the labor market situation in Sweden today there?s no guarantee that the individual will return to the labor market after having undergone job training. The aim of this study is to understand how supervisors at job training activities experience that the organizations of the activities and resources affect their work.

N?r ekonomin stryper En kvalitativ studie om Europeiska unionens sanktionsf?ring i f?rh?llande till ideologiska v?rden och interdependens

This thesis examines the European Union's sanctions policy regarding human rights and interdependence. Previous research has discussed whether sanctions are effective or result in desirable outcomes. This paper aims to take a step back and understand motives by analyzing consistency in the EU?s decisions to impose sanctions. The question is relevant because formal justification can be used to cloak actual motives, and by examining actual decisions, the analyses shed light on motives.

Beräkningsmodell för massbalanser för Slottshagens reningsverk

In the next few years the pollutants loading at the Slottshagen wastewater treatment plant in Norrköping is going to increase due to the reason that one of the waste water treatment plant in the district will be shut down.A survey of how these different pollutants are divided in the treatment process is therefore necessary for mapping out both the loading and treatment efficiency.This can be achieved by studying mass balances.Mass balances were carried out for the water treatment process for the mechanical/chemical,biological and the chemical stage.The mass balance studies show that the treatment efficiency was very good. However in order for the mass balances to be quite consistent and to ensure complete coverage of results and conclusions i.e. more reliable results, sludge samples should be collected and taken at different times per day and the influent rate should be investigated.In this work mass balance has been set up in order to illustrate and identify the factors that should be considered and taken care of for further estimation using mass balances in the future. Furthermore this survey results in a calculating model for the mass balances at thisplant.This calculating model is used as a tool to facilitate future calculations for mass balances for the water treatment process at Slottshagens wastewater treatment plant.Moreover it provides a basis for carrying out further estimation of the treatment process in the near future.In this project the importance of some operating parameters was also taken in consideration.This calculating model can be modified so that calculations of such operating parameters i.e. sludge loading and sludge age can be easily performed.Such information can be used further to evaluate different operation alternative in order to ensure an optimal use of the treatment process with in the plant..

Intellectual Property Rights : A Barricade to Technological Development. An Ethical Analysis on the Less Developed Countries

Debate over Intellectual Property Rights ?IPRs? particularly patent and copyrights is mainly on forward-looking industries in computer software. As part of a trade deal reached in 1994, the member nations of the World Trade Organisation must adhere to a global agreement known as TRIPS, for the Trade- Related Aspect of Intellectual Property Rights.This study is to analyse the ethical conception of Intellectual Property Rights and in particular its implications on the developing countries in relation to TRIPS. The approach will be to analyse a broad philosophical theories of property to see if there is any justification for a software program to be treated as private property and also argue base on John Rawls two principles of justice in relation to TRIPS Agreement. Some reflections will be put on the use of open-source software by less developing countries.From the study it was asserted that, strong IPRs protection would hinder technological transfer and indigenous learning activities in the early stage of industrialisation when learning takes place through reverse engineering.
