Mätning av abrasivflöde för vattenskärningsmaskiner
The content of the following report is the summarized result of three students
thesis at Blekinge Institute of Technology in co-operation with Water Jet
Sweden AB.
This report will give the reader a description of principles how to measure the
abrasive mass flow in a waterjet cutting system.
The work began with a visit to Water Jet Sweden AB to get a closer look at the
problem. When the analysis of the problem was done the criteria were defined in
the form of demands and desires. The main task of the criteria was to guide the
search for the solution. The work proceeded with an extensive search for
abrasive flow meters along with obtaining information about flow measurement in
general. When the search for abrasive flow meters resulted in nothing all the
efforts were concentrated on finding a principle of measurement that could cope
with the criteria.
Skötselns och ståndortens betydelse för kärnvedsbildningen i tall
Heartwood has always been a desirable part of the tree, due to it?s superior decay qualities com-pared to the sapwood. How the formation of heartwood works has been known for a long time, but which factors that initiates and stimulates the production are poorly understood. This case study presents the results of a study in which silvicultural treatments and site properties had a key position as factors to the formation of heartwood. According to the hypothesis the amount of sapwood is directly controlled by the size of the crown.

Äldres upplevelser av kvalitet på särskilda boenden
Old people's life situation when receiving municipal help and care in theirlast period of life is sparsely investigated from their own perspective. Thepurpose of this study was focused on the thoughts of the aged people andtheir personal experiences on what quality is within the geriatric care. Inthis qualitative study, 10 elderly people aged 75-90 years wereinterviewed from 3 different nursing homes within Solna Municipality.Qualitative interviews, with the emphasis on their present life situationespecially what brought about a good life, were performed. The interviewswere analysed using qualitative content analysis. The implication of theterm ?meaningful existence? is individual and differs from person toperson.
Produktionsvåtmarker mot övergödning
In ambition to produce more and better harvests, artificial fertilizers are used to produce a better growth of crops in the agriculture landscape. This contributes to leakage of nutrients. Our forests also exhibit a leakage of nutrients. Air pollution contributes to more nutrients. High precipitation with high water flows as a consequence seems currently to occur more frequently in the county of Halland.
Förtolkning inför skogsbruksplanläggning med laserdata (NNH), eller traditionell flygbildstolkning?
The purpose of this study was to investigate produced laser data from the new national height model's airborne laser scanning in Sweden, what quality it has and whether it can be used for forest management planning. From airborne laser scanning one can obtain information on forest variables such as tree species, height, diameter and basal area. Norra skogsägarna is the principal employer of this project and they wanted know to the quality of the laser data which needs to cope with their standards. If the laser data the quality required it can replace some of the operations performed by field planners.
To examine the quality of the produced laser data a control tax assessment has been performed in 30 forest departments. This was done in an objective manner.
Vilka kvalitetsfaktorer anses viktigast vid inköp av grönsaker och frukt för återförsäljare i Sverige :
Since Sweden joined the European Union all Swedish fruit and vegetables are classified according to EU Quality standards. One important function is the product description and how it can facilitate the trade; for example in better comparing prices and also to guarantee the quality of the product. This quality standards or product descriptions are written as words of an Act and obligatory for all countries that has joined the EU.
It?s often a demand from the customers to be certificated according to some of many certificating systems. One example is the common worldwide GLOBAL GAP-certification system created by the organisation EUREP which represents the leading European retail traders.

Höjning av vattennivån i Mälaren : Ett hot mot Stockholms centrala delar vid en framtida klimatförändring?
In today?s World is climate change an important and hot topic. Climate scenarios for Sweden show a warmer climate, especially during the autumn, winter and spring. The same climate scenarios also show that the precipitation will increase during this part of the year, however, during the summer the opposite is expected to occur. The purpose of this essay is to examine how future climate change will affect Stockholm especially the expected increase in precipitation, which may lead to a rising level of the Lake Mälaren. During 2000/2001 was Stockholm hit by a flood. This flood nearly resulted in major consequences and showed that there were significant risks for the city of Stockholm and increasing precipitation will result in even more water in the drainage systems of Lake Mälaren. The results presented here show that it is important to increase the drainage capacity of Lake Mälaren in order to reduce the risks of flooding in the central parts of Stockholm.

Sjuksköterskors erfarenheter av att underlätta förbättringsarbete i vården
Background: It is required that health care professionals continuously work with patient safety and quality improvements, and the skills of registered nurses are significant in this work. However, quality improvement also requires commitment and knowledge about how to improve health care and ensure patient safety. There is a lack of studies that highlights the importance of supportive functions for this work. Nurses in clinical settings can be utilized as facilitators that make things easier for other health care professionals who are engaged in quality improvement and patient safety. In order to gain understanding about the significance and needs of nurses with a role of facilitator, it is urgent to learn from their experiences of facilitating quality improvement in health care.Aim: The aim was to study nurses? experiences of facilitating quality improvement of nursing care, patient safety and multi-professional collaboration in health care.Method: Semi-structured qualitative interviews were performed with ten registered nurses who had experience of being in the role of facilitators.
En uppföljning av floran i Enköpings vattenpark : kan anlagda våtmarker med vattenrening som huvudsyfte bidra till naturvård och biologisk mångfald?
Wetlands are important ecosystems and form habitat for both common and threatened species. In Sweden, as well in many other places on earth, there is a lack of wetlands. There is an expressed will to adjust this lack through restoration of wetlands with reduced function and through construction of new wetlands. Follow-ups and evaluations are important steps to optimize these actions. The wetland Vattenparken was constructed 1999 ? 2000 for treatment of surface water.
