The RECK gene and invasive cancer development : the significance of RECK in angiogenesis and inhibition of matrix metalloproteinases

The RECK gene is a relatively new discovered gene with important implications for cancer research. The research has been primarily concentrated on the human gene with the ultimate aim to identify the invasive characteristics. Up regulated RECK is linked to significantly prolonged survival rates in patients with severe forms of malignancies. RECK is normally expressed in all cells of the body and has an important role in the balance between destructive and constructive features of the extracellular matrix. The RECK protein is a membrane-bound glycoprotein that inhibit matrix metalloproteinases which has the function of breaking down the ECM. There is a significant correlation between RECK gene expression and the formation of new vessels, presumably via the mediation of VEGF which is an important and powerful inducer of angiogenesis.

Systemutveckling och användbarhet -Att utnyttja användbarhetstester i systemutvecklingsprocessen

Den här rapporten behandlar frågeställningen om hur man kan anpassa systemutvecklingav ett informationssystem enligt livscykelmodellen till att inkludera användbarhetstester. Frågeställningen grundar sig i att god användbarhet inte är ett explicit uttryckt mål i Andersens beskrivning av livscykelmodellen. För att besvara frågeställningen har vi utvecklat och testat ett bokningssystem åt en mindre verksamhet. Utvecklingsarbetet har bedrivits enligt en egen anpassning av livscykelmodellen. Testerna har utförts enligt metoden cooperativ evaluation.

Sol, jord och vatten. : Barns tankar om den ekologiska processen

Studies show that the interest and knowledge about science among teenagers is decreasing. They also reveal the difficulties to explain the ecological processes and that the ideas about the nature are collected from everyday life and early school years.The intention of this investigation was to find out more about children?s ideas and knowledge about the ecological processes and to compare these results with the curriculum.The method was a questionnaire and interviews with children in school year 1 ? 6. The aim of the studies was also to find out if any progress connected to age could be found, concerning understanding of the ecological processes.The results showed difficulties in achieving the predestined goals for biology and chemistry concerning ecology cycles and they differed a lot between the children. Often the learning process showed very little progress.

Ett språk för alla? : en kvalitativ studie av ett antal pedagogers syn på sinanvändning av IKT-verktyg i den tidiga läs- och skrivinlärningen

The aim of this study is to investigate a number of class teachers' thoughts on the use of information and communications technology (ICT) in early literacy learning. The study has been conducted as a qualitative study, interviewing five teachers with the help of an interview guide. Three central questions were posed.What perception do the teachers have about the use of ICT in their tuition?What perception do the teachers have about the pupils' literacy learning in teaching with ICT tools?What perception do the teachets have about teaching and learning by means of ICT when it comes to pupils with reading and writing difficulties/dyslexia?The overall theoretical basis of the study is Vygotskij's sociocultural theory.In conclusion, the result of the study is as follows.Most class teachers feel that the training they have undergone in ICT education was adequate, but they also call for skill development.Most teachers believe that the use of ICT tools provide opportunities to adapt their teaching to pupils' knowledge level. The teachers' opinion is that ICT in teaching is useful for pupils' progress in early literacy learning.Most teachers also believe that ICT tools in teaching can be of some help for pupils with reading and writing difficulties/dyslexia.One obstacle in helping these pupils is lack of time.Therefore, the majority of the teachers hand these pupils over to special education outside the classroom..

Underlag till klimatledningssystem för skolor

The climate issue is a significant question, and the problem is mainly caused by human activities. Everyone can help to counteract the enhanced Greenhouse effect by reducing the amounts of energy they use and by not consuming more products then they need.Schools are some of societies many consumers and therefore contribute to the Greenhouse effect. The School also has an important task; to teach and disseminate knowledge and information about the climate and the environment. According to the Swedish National Agency for Education, Skolverket, must all schools regularly consider the environment and sustainable development throughout the entire education process. Unfortunately, this is not the case for many schools in Sweden today.One of many tools that can be used to coordinate environmental work and initiatives, and also to make it more efficient, is environmental management systems.

Tänk om hon ville leka titt ut? : En essä om olika förutsättningar till kommunikation hos barn med flerfunktionshinder

My essay begins with a story in which I portray different communicative situations at the preschool unit Myran. The children in my story are at an early stage of development and they all suffer from multiple disabilities which inhibit their ways of communicating. Through my story, I describe how I perceive different communication dilemmas in my work place. A difficulty I cover in my essay is how the educator knows if he or she has interpreted a child correctly when it does not have a verbal communication and therefore is completely dependent on the educators? interpretations of its communication efforts.

Vad betyder min novell? : Författaren tolkar sin okända text

All my short stories have been written in an intuitive way according to which no outline of characters, intrigue or plot was made in advance. A consequence of this process is that not even myself as the author is aware of the meaning of the texts and therefore I too have to interpret the stories. Because of the character of the text, I use an analysis of archetypes according to C. G. Jung?s analytic psychology.

Leder kastrering av hanhundar till bättre djurvälfärd?

Castration of dogs holds many reasons and opinions, therefore methods, traditions and rea-sons vary. The approaches have during time changed from mostly surgical castrations to also including hormonal treatments. Castration is used to control the dog's reproductive abilities, for medical reasons and to possibly rectify problems of behavioral nature. How common a particular method of castration is in a country is highly dependent on the country's traditions. In Sweden it is most common with castration for medical reasons, such as possible elimina-tion of diseases, for example, benign colorectal tumors.

We have noticed that there is a trend of being healthy and fit today. ?Strong is the new skinny? is a quote we can see in social media and on blogs today.

Skyddsombudets Roll : En undersökning av skyddsombudets säkerhetsarbete på byggarbetsplatsen

Safety in the construction industry has become a question of top priority in recent years. Despite a massive investment of time, money and knowledge, the occur-rence of fatal accidents in Sweden alone is around one a month.The purpose of this study is therefore to improve the safety on the construction site. By an examination of the role of the safety agents and their cooperation with the construction workers and supervisors as well as examine how safety agents can improve safety on the construction site, which is the goal of the study.Four questions were formulated based on the purpose and the goal of the study.The methods used to answer the questions were a questionnaire survey, multiple interviews, a literature review and a document analysis.The report describes the safety agent?s role as a complex one with many different tasks. The role of the safety agents is regulated in the health and safety law, but it can sometimes be difficult to interpret and the agents can therefore interpret their role differently.

Innovationsstöd i tidigt skede : hur påverkas Sveriges internationella konkurrenskraft

In a globalized world, competitiveness is based on the high IP (intellectual property) of our export products and innovations are therefore important for new companies to establish and develop. It´s not enough to just have big international companies but it is also necessary to invest in new companies that can be competitive in the future. By helping entrepreneurs with innovation support in the early stages, new technology-based businesses are established and developed. The purpose of this paper was to examine how innovation support in the early stages affects the establishment and development of new technology-based companies. Furthermore, we investigated how this will affect Sweden's international competitiveness.

Värmeförluster vid utvändigt placerade ventilationssystem

To be able to handle tomorrows need for limited energy consumption we need to reduce our use of energy. The building sector stands for around 40 % of all energy consumption in the society. The government has put up a goal to reduce the energy consumption in our buildings with 20 % by year 2020 and 50 % by year 2050 compared with year 1995. To be able to do reach that goal we need a more energy efficient building stock.The main part of the energy used in our buildings is used for space heating. By installing ventilation systems with heat recovery on the exhaust air it is possible to use the heat-energy in the exhaust air to warm up the incoming air.

Ants and termites in small-scale plantain farms in Uganda : a comparison between agroforestry and non-agroforestry farms

This study was conducted in Kkingo district, west of Masaka, Uganda. It compared soil macrofauna abundance in non-agroforestry farms with that of agroforestry farms. The agroforestry farms had participated in the Vi Agroforestry´s program between 1995 and 2006, and continued on their own after 2006, when Vi Agroforestry left the area. The soil macrofauna is important for soil structure and processes that are contributing to soil organ-ic matter decomposition and nutrient mineralization. They are also predators of potential pests.
