The purpose with the report is to show that it is possible to design a class-D amplifier, using a programmable FPGA mounted on a developing card from Xess and a H-bridge. The FPGA was programmed in VHDL which is the language the software from Xilinx use to implement a logical function into the FPGA The logical function corresponds to a modeling of the music signal and the modeling can be described as a comparator which compare the music signal with a triangle wave and as a out signal produce a pulse width modulated (PWM) signal. The report is also a review and evaluating of two different modulating technologies, AD- modeling and BD-modeling. A detailed part about how the H-bridge was designed and how it works. The result of this project is a working audio amplifier to a significant lower price than the products in todays market..

The paint market of today is a jungle whit an enormous range of different paint types; there all has different properties and different compositions, some with big influence on the environment and some whit less influence on the environment. It could even be difficult for an expert to always know what should be used on which surface and what would be the best out of the environmental point of view.This work is not intended as a total review of all the manufactures range of colours; only as a deeper dissertation about distemper paint in general, in particular Falu Red Paint. Whit focuses on the environmental issues.The work is especially for those who are ready to paint but don?t know what paint they should chose and people that has a interest in paint and environment, perhaps it also could be of interest for professional painters even when there probably isn?t any big news for them. The information is compiled from the Internet and downloaded brochures from the Internet..

This paper addresses the need to review the modern presentation of textile archaeology in museums. It is time to look at textiles in archaeology with new eyes. The reality behind archaeological textilestudy is holistic, embracing many different aspects of society. The presentation of textiles has in my opinion become old-fashioned. I will show in my paper that Jonathan Adams? `seven constraints´ model, developed for research on ancient ships, can also be applied to textile research.

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.

Venous leg ulcers are a chronic disease mostly among elderly individuals. The leg ulcers are often painful and interfere with the individual?s daily life. The aim of this literature review was to describe individuals? experiences of living with venous leg ulcers.

Background: A patient undergoing surgery will meet many caregivers in different settings pre-, intra- and postoperative in the surgical pathway. Lack of communication is a common digression and the handoff is such an occasion. The purpose is to describe current knowledge about the patients´ right to safe care perioperative. The study is a systematic review (pilot). Result: The handoff was informal, unstructured and inconsistent.

För ungdomar som är mitt uppe i frigörelseprocessen från föräldrarna kan det vara en känslomässig balansgång när en förälder insjuknar i cancer. Det är viktigt att denna oro uppmärksammas och bekräftas för att inte ge långsiktiga negativa konsekvenser. Syftet med litteraturstudien var att belysa ungdomars reaktioner när en förälder har cancer. Studien genomfördes som en allmän litteraturstudie. Nio vetenskapliga studier inkluderades i resultatet.

To become old and live in an institution could mean that the habits and routines they have obtained during their lifetime and are used to may become changed. There are fixed norms and rules which the elderly more or less have to adjust to. The aim of this study was to describe how nursing staff attitudes influence on elderly care takers meal situation. The method of this study was a literature review. The result showed that norms and rules not always are adjusted to caretakers? wishes and needs.

Aim with this literature review is to acqurie knowledge in medical, psychical, psychological and social problems evolving urine incontinence and it´s treatment metods, current legislations and the nurse´s approach towards the patient and transcultural care if the patient comes from another cultural.The results show that this problem affects the women´s life situation enormously above all it brings them a increased social isolation, helpless, sheme, psychological and sexual problems.the nurse should recognise demands and resource with the.by support of diagnostic care, patients can achive good health when there is enough resource patient to be able to support her in her efforts to achive balance i her daily life..

Thermography is the assesment of the surface temperature of the horses body and it falls into the categori of physiological imaging. Thermography allows us to portray inflammation and changes in sympathetic tone in a graphical manner. The purpose of this study was to review thermography in equine medicine and to evaluate thermography as an aid in the diagnosis of lamness in horses. Thermography has been helpful to identyfy sprains, stress fractures, shin splints and soft tissue, tendon, ligamentous and nerv injuries and to monitor healing processes during rehabilitation. Routine thermography may reveal inflammatory responses prior to clinical signs. In present study thermograpy gave especially valuabel information in two cases. In one horse reduced blood flow in a. saphena due to a thrombosis were visualised and in the other horse bilateral thoracolumbal radiculopati was diagnosed.

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.

The Swedish building and property management sector are responsible for about 30 % of the total energy use. In order to take environmental consideration, different environmental assessment tools and standards are used. Miljo?byggnad, Svanen, FEBY12 and PHI are some of these. There has been increased interest to certify buildings and therefore it is of interest to evaluate the assessment of the energy field to see if relevant energy aspects are assessed.

The purpose of the literature review was to illuminate how family are responded to in health care and their experiences with a sick person in the palliative care. Ten articles dealing with the questions have been used. The questions emphasized how family experienced the response from people working within health care, their own situations and if they felt they were sufficiently informed. The results were presented from out in the questions in two themes families positive and negative experiences. The results show that for the families to have positive experiences of the respons, the situation and the information given, the working within health care have to make families feel part of the palliative care, to the extent they wish to participate..

Most swedish newspapers have a homepage where their news are presented. Existing guidelines describing how to write for the web often recommends you to keep it short and stay objective. But how about longer pieces of content presented in the print version? What will become of reports, interviews and essays as we?ve come to know them as the printed newspaper goes digital?Interviews with representatives of five swedish newspapers shows that the extent to wich content is being published on the web is connected to the overall purpose of the web presence. The fact that many newspapers does not publish longer pieces of text on the web rather seems to be an economic issue, than a matter of good readability.Past studies shows that longer pieces of text may well work on the web, if the reader?s interest is big enough.
