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.

In connection with that the last few decades have been characterized by major changes where also the rate of change has increased, changes in organizations has become a natural part of today's organizational activities. Every change involves a learning challenge and because of that every change is unique, its output is unclear. However, there is much research that highlights various factors critical to creating an effective change, among others internal communication.The purpose of this study is to investigate whether Engeström's theory can be applied to a completed organizational change and see whether an expansive learning has been promoted in connection with this. This is accomplished through interviews with six employees, all working in one of Sweden's leading property companies. Engeström's theory of expansive learning is applied in order to analyze whether learning is promoted in connection with the organizational change.The result of the study shows that Engeström's theory can be applied to a completed organizational change in order to analyze whether an expansive learning has been promoted in connection with this.

Ocean Thermal Energy Conversion, OTEC, is a sustainable energy conversion technology that is not yet commercialized. OTEC is a technology that utilizes the temperature difference in oceans between the warm surface water and the cold water at 1 000 m depth to run a Rankine Cycle. This technology can produce electricity and provide synergies like fresh water, air conditioning and aquaculture. A simulation program for three alternative OTEC systems has been created in order to decide which OTEC system is most profitable; closed, open or hybrid system. In this simulation a production cost analysis is performed in order to investigate and decide which one of the three systems that has the lowest production cost. The production cost analysis also analyzes if the profitability is affected by the size of the facility. After these analyzes, the most profitable of the three different OTEC-systems is expanded by an installation of solar collectors in order to see if the thermal efficiency is improved. The result shows that the most profitable system varies with the size of the facility.

The aim of this bachelor thesis is to examine the collaboration between school librarians and teachers in primary school, in order to illustrate how the two professions can work together, how they see their own roles and how they look at the other professionals´ roles. We also discuss earlier studies in LIS concerning collaboration between teachers and librarians. The method of investigation is qualitative interviews with practicing school librarians and teachers, we interviewed three school librarians and three teachers from three different schools in the same county.  As a basis of the discussion and analysis Andrew Abbott's theory of professions is used. The thesis shows that collaboration differs between the schools.

The purpose of this essay is to describe the organization of the Swedish Animal WelfareAgency during the time it was in operation. The Swedish Animal Welfare Agency was established in 2005 by the government who saw it as necessary in order to strengthen the protection of cruelty to animals in Sweden. However, the agency was shut down already in2007 and its responsibilities as an agency was moved back to the government and the department of agriculture. During its time in operation, the Swedish Animal Welfare Agency, received much criticism, among other things because of its interpretations of the law which were seen as too focused on details and thus ?bureaucratic?.

A well, situated on Listerlandet in the western part of Blekinge in Sweden, has a very high content of nitrate. Water with a too high content of nitrate is hazardous to human health, in particular to small children. The area surrounding the well is mostly drained agricultural land with some larger farms for chicken and mink. The well takes its water from the bedrock and is deeper than most other wells affected by nitrate. The bedrock in the area is dominated by limestone with a relatively high flow of water.This thesis was performed in order to find the source of the nitrate.

Introduction and research question:  This study investigates the widely discussed notion ?Corporate Social Responsibility? and its practice in the tourism industry. In the contemporary society more companies are realizing the significance of Corporate Social Responsibility (CSR) and its potential as a means of differentiation.  The author?s interest in this particular phenomenon was awakened after reading about the business case of Scandic Hotels. This is a company that nowadays is referred to as ?Scandinavia?s leading hotel chain?.

Lean is one of the recent years most popular methods for organizations to use in order to increase efficiency, productivity and quality. Despite Lean's increased popularity, Lean is still difficult to define and can be explained and described in different ways. Previous studies have also shown that Lean is difficult to implement and challenging to maintain successfully. Knowledge of Lean is viewed as a necessity in the implementation of Lean, which leads to that organizations often chooses to bring in this knowledge through external consultants or other experts in order to implement Lean in their organization. Thus, it is interesting to examine the consultants view on Lean and the implementation process of Lean.

I Sverige finns det ungefär 475 000 hektar skogsmark där den från Kanada introducerade contortatallen (Pinus contorta) utgör mer än 65 % av den totala grundytan. Genom aktiv skogsanläggning har P. contorta blivit Sveriges sjunde vanligaste trädart sett i ett volymmässigt perspektiv. Därför är det av stor vikt att ha god kännedom om hur arten sprider sig i det svenska skogsekosystemet. När P. contorta introducerades ansågs den sakna förmåga att självsprida sig (fröså sig), men senare visade det sig att andelen serotina kottar varierar mellan olika träd och att den kan självsprida sig på produktiv skogsmark. Resultatet av studien visar att P.

The purpose of this study was to find out how gender roles are described in two popular children?s detective stories, one of them written in 2002 and the other in 1946, to be able to compare the two. In order to do this, I used a qualitative research method in which I read and analyzed the text and illustrations of the books out of a gender perspective.I used gender theories describing how stereotypical gender roles are displayed, and these theories were later associated with the books I studied. I also used previous research concerning gender roles in other children's books in order to compare those results with my own.After having read, analyzed and compared the two books, I found vast resemblances between them, but also certain differences. However, it is obvious that the gender roles in both books for the most part are traditional.

This is a tale about energy and power. It describes the geographer Halford Mackinder?s geopolitical theories and compares them with current views outlined by Zbigniew Brzezinski and Michael T Klare, among others. With a critical approach it also provides a historical account of a Europe that stands in front of an energy struggle so severe that the current world order seems destined to fall. Oil and natural gas, has since the beginning of the 20th century, been used as a geopolitical tool in order to create dependence, control and even sometimes overthrow empires.

This report is a master thesis performed by Adam Lundin at the company Sandvik Coromants production facility in Gimo. The work started in January 2013 and went on for the duration of 20 weeks, which is equivalent to 30 hp. The project was executed at the department GVR10. The scope of the project was to create a base for improvements in the purchasing process of direct material to the production. The background to the project was that the centralized purchasing department has gone through changes and decision was taken to decentralize the purchasing of direct material to Gimo.

Ruins and derelict places have since long fascinated and attracted humans. With my starting point in the wild vegetation and the spontaneous activities taking place on derelict land and in industrial ruins, I explore with help from the theoretical sociology, what creates not only this fascination but also fear. The purpose of the thesis is to explore and exemplify how the industrial ruin as a place outside the restrictions and control as well as design intentions of modern society can be used as an inspiration in a landscape architecture context.The modern city consists of areas and places with a well defined purpose. A piece of derelict land or a disused building is instead ambiguous, undefined and open for new purposes. However described in negative terms, these placesare often perceived as places of mystery and magic.
