Syntes och struktur i SAB förr och nu: En studie av avdelningen för språkvetenskap genom den första, den fjärde och den sjunde upplagan

The aim of this masters thesis is to examine the synthesis and the structure of the main class for linguistics F in the Swedish classification system SAB. We want to find out whether F has developed towards a more faceted structure or not. Our theoretical perspective is based on fundamental principles for modern classification. To carry out our investigation the first, the fourth and the seventh edition of SAB is analysed and compared. The results of our study show that the main class F has become more faceted and therefore the possibilities to use synthesis have increased.

The control of the cell cycle with particular emphasis on the G1/S transition

Tumour development occurs to a large extent because of dysregulation of the cell cycle. Of particular importance are defects occurring in the G1 phase. The reason why G1 is critical is because of the influence of several signals (external signals as well as cyclins and cdks) on this stage. The G1 phase can be divided into two parts, G1pm and G1ps. Each part has its ?own? restriction point which needs to be passed in order to progress to S phase.

Karaktärisering av hund TK1 för användning som tumörmarkör :

Thymidine kinase 1 (TK1) is an intracellular enzyme involved in ?the salvage pathway? where the uncomplete parts of DNA are transformed into DNA precursors. The expression of TK1 is cell cykle specific, with the highest level during S-phase when DNA-synthesis is most active. One kind of TK1 is present in serum and an increase in TK1 activity in serum is due to either the level of DNA synthesis in the body or the number of cells dying in a state of replication. This can be used and is used as a marker for prognosis and evaluation of treatment in human patients with leukemia and lymphoma.

Reuse, reduce & recycle : planning for sustainable solid waste management in Stone Town - Zanzibar

In the low-income countries of the world, rapid urbanization and decaying infrastructure results in an increasingly unsustainable situation when it comes to solid waste management. Often, the solution tends to focus on introducing technical advanced interventions based on the conditions of the high-income world. However, this thesis aims to ?nd site-speci?c solutions on solid waste management at a local scale. By taking in consideration of local conditions a customized approach is possible where the solution is not dependent on expensive structural changes.

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.

Talsyntesen ? Dyslektikerns glasögonoch ett stöd för många läs- och skrivsvaga

According to the National Agency for Education 06-06-2010 are approximately 115 000 students graduating from Secondary School in the year of 2010.Out of these students, we know that thousands of them are hampered by reading and writing disabilities in various degrees. Have these students been given the best support needed when it comes to writing and reading?Compensation may be perceived as a goal for the pupil to catch up with the rest of the educational group or as a vehicle to go round the difficulties. In Sweden, diagnosed dyslexics are not allowed to use speech synthesis, a compensatory technical aid, during the 9th degree national tests.This study?s purpose is to discover if the usage of speech synthesis during the national test of Swedish and reading comprehension might work as a motivation booster for the students and consequently increase their test scores.This is a quantitative study including study including 15 pupils with diagnosed reading and writing disabilities.

Re-Design av Dagens ETC

The project is about making a Re-Design of the Swedish Socialistic Newspaper ?Dagens ETC?. The background to the project is my search for commitment when I work with a specific customer or project and how importantthat commitment are?The project was from the beginning split up to three different phases. The meaning of the first phase where to make a re-design mainly based on a interview with Johan Ehernberg, the chef editor on ETC.The second phase was a design totally made of my own idea and creative view as a Graphic Designer.I had in mind to make the third phase based on the result of the first two phases.During phase one and two I reconsidered and decided to skip the third step and put more effort in to the two first ones.

Populärmusikscenernas finansiering: en fallstudie av Pinkerton

The purpose of this thesis was to describe the economic situation for popular culture venues. During the study, four different ways of financing were encountered. These are sponsorship, volunteers, government funding and ticket sales. A case study, based on interviews, were conducted on Pinkerton, a non-profit organisation. The result showed that Pinkerton needs a solid subsidy from government funding.

SSDs påverkan på MySQL: En prestandajämförelse

Solid State Drives (SSD) blir idag allt vanligare som lagringsmedium och håller på att bli ett alternativ till magnetiska hårddiskar. Denna studie+ har undersökt hur man på bästa sätt kan utnjytta SSDer i en MySQL-databas. Undersökningen genomfördes med hjälp av experiment där prestandamätningar gjordes för att få en klar bild på i vilken konfiguration av SSDs som ger bäst prestanda i MySQL. Mätverktygen som användes var sql-bench och mysqlslap.   Resultaten visar att en databas på en enskild SSD presterar lika bra som en databas med  SSD-cache  under  majoriteten  av  mätningarna  och  visar  bättre  resultat  än resterande konfigurationerna som var en databas på hårddisk och transaktionsloggen på en SSD. .

Latent värmelagring i vattenburet uppvärmningssystem med elpanna för byggnadsapplikationer

Latent heat storage is a way to store thermal energy when a phase change material undergoes a phase change. The advantage of latent heat storage is the capability to store more energy per mass unit than other heat storage methods. The most commonly used phase change in latent heat storage is the transition between solid and liquid. Phase change materials can be divided into organics, inorganics and eutectics.In the Nordic electricity market the price of electricity is set every hour by Nordpool spot, which leads to price fluctuations because of changes in demand. The main goal of this report is to create a latent heat storage system in a single-family home and investigate the possibility to save money by charging the latent heat storage system when the price of electricity is low, and discharge when the price is high.The thermodynamic model consisted of a ?tube-in-tube? heat exchanger with phase change material in the outer tube and water as the heat transfer fluid in the inner tube.

Intresse och närvaro : Patienters upplevelser av sjuksköterskans närvaro i vårdandet

Background: Research shows that the nurse?s presence has a great significance for the relationship between patient and nurse. By this, the nurse can gain a greater understanding for the patient?s situation and thus have an opportunity to influence the patient?s health processes.Problem: Today?s focus on the technology and lack of time in healthcare can create a stress which can make it more difficult for the nurse to prove presence to the patient.Aim: To describe patients? experiences of the nurse?s presence in healthcare.Method: A qualitative approach, where Evans descriptive synthesis has been used. Eleven previously published qualitative, caring science, articles has been used in the synthesis.Results: The synthesis revealed two themes.

Upplevelser av att leva med medicinsk teknik

The purpose of doing this essay was to illustrate how people living with chronic disease, dependent on medical technology experience their life situation. The study includes people with either dialysis therapy, mechanical ventilator or chronic oxygen therapy. A meta-synthesis was used as a method where a systematically review of studies that are made in a given issue compiles. Findings of the studies resulted in a synthesis of three themes: Limitations in life as a consequence of life-long treatment, to take responsibility for your life provide self-esteem and safeness, and to be cared for in different contexts ?help or prohibit.

Genetisk variation av betydelse för adenosinsignalering vid nydebuterad reumatoid artrit

Rheumatoid arthritis is an autoimmune disease, where joints are attacked by the own immune system, leading to chronic inflammation and destruction of bone and cartilage. Inflammation is a complex process, controlled by many different substances. One of them is adenosine, which has anti-inflammatory properties. In this project, three polymorphisms in different genes, involved in synthesis and signaling of adenosine, were genotyped for 188 patients with RA and 362 controls without RA. The results shows that for the polymorphism in A2a, a gene coding for an adenosine receptor, there was no significant difference in genotype distribution between the groups.

Fluidrörelse- och värmetransportsmodellering i götugn

The purpose of this thesis for Sapa Heat Transfer is to examine a furnace in which aluminium is pre-heated before hot rolling. The project is modeled in a computer environment in which the air flow in the furnace and the heat transfer to the aluminium solids are included. The computer environment and its governing equations, as well as boundary conditions and generalizations, are presented and explained.The simulations are based on two models. The first model has an asymmetric solid placement, which is how it looks in today's ovens. It is validated against collected data.

Playplus : Utveckling av produktkoncept för aktivitets- och inlärningsmotiverad lek

In a society where adults set the conditions for children?s play and generate modern and at times technically advanced products, fundamental characteristics like simplicity, opportunities for motor skills training and learning tend to be neglected. Owing to this, the Linköping-based company Time In wants to introduce a new multifunctional product, which differs from other products in shape and function and lives up to the often overlooked, basic characteristics in a toy.With Time In as the assigner, the purpose of this master thesis has been to use simple means to produce a "learning by playing" concept. Since Time In sells toys and products suitable for children in nurseries and preschools, the development of the products has therefore included a study of nursery and preschool environments.The thesis has been carried out within the Product Design subject area at the Department of Management and Engineering at Linköping University. Concept development has been done in three phases: the Preparation phase, the Design phase and the Presentation phase.
