This report present the design and manufacturing of a wide-band driver amplifier placed in radar module for airborne applications. The major goals for the amplifier were a high efficiency and to deliver a predefined output power. To reach the second goal an additional preamplifier had to be constructed. The amplifiers were constructed in three steps: Design and Layout in the software Microwave Office, Mounting components and Verification. The driver amplifier was decided to be a push pull configuration consisting of two parallel transistors biased in class AB.

The purpose of this Master?s thesis is to investigate what prompts student nurses to seek information required to their educational tasks and how they evaluate and utilize that information. The questions addressed in this thesis regard how information retrieval becomes part of student nurses? social practice; which physical and intellectual tools student nurses make use of in their education; and which mediating resources they use to perform their tasks. Roger Säljö?s sociocultural approach provides the theoretical framework for this thesis.

Vinderosion på jordbruksmark har länge varit ett välkänt faktum trots att någon utförligare undersökning om dess omfattning och skadeverkan inte tidigare genomförts. Mot bakgrund av detta har därför ett nordeuropeiskt projekt, WEELS (Wind Erosion on European Light Soils), dragits i gång som syftar till kartlägga vinderosionen på sandig jordbruksmark i norra Europa och som man i slutändan hoppas ska kunna resultera i en vinderosionsmodell. Detta har genomförts med SOIL modellen, en matematiskt fysikaliskt baserad modell för simulering av vatten och värmeflöde i en skiktad jordmånsprofil..

Skådespelaryrket kräver mycket av en människa både intellektuellt, färdighetsmässigt och fysiskt. Det förväntas också ofta av en skådespelare att vara musikalisk. Musikalitet kan yttra sig på olika sätt. I skådespelarsammanhang vill jag påstå att musikalitet kan finnas i allt från texthantering till hur man rör sin kropp. Jag är rytmikpedagog, men har också arbetat som skådespelare.

Under de senaste 300 åren har jordbrukslandskapet i Sverige genomgått stora förändringar. I början av 1900-talet introducerades konstgödslet och efter andra världskriget ökade gödslingen dramatiskt i syfte att maximera produktionen. Detta har lett till att överskottet av kväve har spolats ut i vattendragen. I detta arbete har stor vikt lagts vid att skapa en egen kvävemodell i syfte att simulera kväveläckaget från jordbruksmarken i Tolångaåns dräneringsområde..

Den psykosociala arbetsmiljön har förändrats. Sedan 1990-talet har andelen sysselsatta som blivit sjukskrivna till följd av stress eller psykiska påfrestningar i det närmaste fördubblats. Syftet med denna studie var att kartlägga arbetsrelaterad stress bland tjänstemän med förhoppning om att använda denna kunskap för att utveckla preventiva arbetsterapeutiska insatser. Studien baseras på en fokusgruppdiskussion med fyra deltagare från ett byggföretag i södra Sverige. I resultatet framkom att tjänstemän upplever arbetsrelaterad stress vid flera olika situationer under en arbetsdag.

Soil organic carbon (SOC) stocks and fluxes in forest ecosystems are influenced by natural and human disturbances. In the tropical regions the highest impacts on disturbance in forest C cycles are related to human activities such as conversion of natural lands to cropland and pasture areas and to forest plantations. The disturbances in the forest C cycles will release CO2 emissions to the atmosphere triggering global warming. In this study the focus was set in subtropical soils in Brazil, south extreme region of Bahia. The aim of the study was to investigate whether reforestation of Eucalyptus plantations under former pasture areas will help mitigate climate change through carbon sequestration.

This master?s thesis describes the development of a model of the catalystsystem aiming at control by an MPC. A well functioning model, which is suitable in control purpose, is important while emission legislation become more and more hard to fulfill for the car manufacturers. Much research has been done in the field of physical modeling of the system, but in this work a linear adaptive time discrete ARX-model is developed and validated.The systems tendency to change its dynamic during usage implies that the model must be adaptive. The developed model proved to be well functioning and shows promising conditions for the MPC design.

The International Organization for Standardization (ISO) proposes vibration standards for the evaluation for machine damage due to vibration in rotational machines, where some vibration parameters are given to measure the vibrationgrade. This work evaluates the relevance of the vibration standards in hydro plants that are proposed by the ISO, and also investigates if there are methods used in other countries could have greater importance. Through statistical analysis of collected data we got a better understanding of relation among different vibration parameters, and also the importance of correct choice of the parameters for the evaluation of vibration. We have found that the vibration standards available today in hydro plants are not reliable for the judgment of vibration?s grade.

This candidate essay is built on literature studies and discusses the meaning of the residential yard along with what you, as a landscape architect, should think about when you are designing functional residential yards. To do this I found it necessary to figure out what it is that makes people step outside their own apartment and out into the city?s public places. The reasons for this are numerous and many times individually affected. Something that plays a role in people?s outdoor life and prevents them from spending time outside is the lack of time, the technique of today and the feeling off insecurity.

The aim of this study was to increase the knowledge about and deepen our understanding for people who are treated with dialysis in aspects of quality of life and coping strategies. The research questions were: How does the scientific literature describe quality of life and coping strategies from people?s perspective who are treated with dialysis? How does dialysis affect patients and their lives? How/what can the nurses do for people who are treated with dialysis to keep or improve their quality of life. The result is based on eight scientific articles and after interpretation of the result we found six themes that describes how patients have to restructure their lives to a new normal life, how they adapt to a life with dialysis treatment, how dialysis affect their physical condition, witch meaning does the family and others have, how they keep their self-esteem in relation to the dependence of dialysis treatment and which factors are associated with a long life with dialysis..

The study reported has been conducted in care service guided by the Swedish law LSS( LSS- act concerning support and service for the disabled). The aim of this study is to examine the experiences of the personnel who have attended the Taktipro introductory course with special focus on how they describe the possible effects this may have had on their daily attendance to their special needs users.The method used is a qualitative method of enquiry, based on interview questions sent by mail to all the participants of the Taktipro introductory course. The result shows that the personnel have a positive view on skills in progress and that this program has facilitated the contact between personnel and their special needs users. An awareness about the importance of physical contact has also been revealed as well as an awareness of their own impact on situations at work. The result also indicates that the personnel feel that they have been able to improve the well being for the special needs users. .

A study based on the consumer buying decision process to discover the typical use of the Internet in the consumer buying decision process when buying clothes. The matter is researched through an Internet survey which discovers how the consumer use the Internet in each step of the buying decision process by using predetermined options. As a result, the conclusion is that people most commonly use the traditional alternatives in the buying decision process of clothes. However, information about a product is often collected on the Internet, mostly on different webshops. The main reason, for people to buy clothes on the Internet, is that the consumers consider it is more convenient and time saving.
