FSC (Forest Stewardship Council) is the major form of certification system in Swedish forestry today and its more than 11 million hectares are covering almost half of the total productive forest area in the country. Its regulations prescribe that at least 10 wind firm trees should be left behind after every clear cutting operation.
This study have taken place on 30 recently clearcut objects in Bergslagen, Sweden, were an inventory of the standing stock have been made. The research shows that, with 90 % security, the retained trees together contain 9-13 m3sk per hectare. Pine is the dominant tree and it covers more than half the numbers of retained trees and its volume cover 65 % of the retained trees total volume. Spruce is on second place with 30 % of the retained trees, but only 21 % of the standing stock.
Ersättning för markåtkomst avseende tredimensionellt (tunnel) intrång i fastighet
Chapter 1. 1 § jordabalken (1970:994) defines property as land that includes area, which is divided into properties.A three-dimensional property must be firm with a closed volume where top and bottom are specified. The property boundaries are described clearly according to Chapter 4. § 27 fastighetsbildningslagen. A three-dimensional property can undermine a traditional property, as well as a three-dimensional property.
Etablering av höstraps i mellansverige :
The production of oilseed rape is an important issue in Sweden and those who never have grown oilseed rape (OSR) are now willing to try. It is always a risk to grow oilseed rape, specially winter OSR, because of outwintering. This risk increases as you go north and therefore establishment and autumn growth is very important. These are some of the reasons that I have chosen to write about the establishment of winter oilseed rape in Middle Sweden.
There are many factors that influence the outcome of the establishment, e. g.
Vårdpersonals upplevelse av att vårda patientermed diagnosen afasi efter stroke : En litteraturstudie
Background: Stroke is one of the leading causes for longlasting sequelae, among themloss in cognitive function, like aphasia. Aphasia effects the patients ability to understandand express themselves in speaking and writing. To be able to reach a good level of care,the careproviders and patients ought to have the same goals and values. This requires agood communication between the careproviders and patients. Which can be problematicfor the caregivers when they don't feel secure in their way of getting close to these patients.Aim: The purpose of this study was to illuminate caregivers experience of caring forpatients with the diagnosis aphasia following stroke.Method: This is a literature study where nine studies, with qualitative design, has beenanalyzed and compiled.
SAS EuroBonus ? Tillgång eller skuld?: En fallstudie av hur värdet av ett lojalitetsprogram påverkar internprissättningen
This paper presents a study of Scandinavian Airlines? (SAS) frequent flyer program, EuroBonus. The study describes the transfer pricing of award seats between EuroBonus and the airlines within SAS. Furthermore, it aims to determine what effects market-based transfer pricing would have on EuroBonus, the airlines within SAS and consequently on the SAS Group. We have found that the existing transfer pricing does not provide incentives for the airlines within SAS to satisfy EuroBonus? demand for award seats.
Automatiska registreringar som kan påvisa brunst hos mjölkkor
Med dagens växande besättningar är det svårare att upptäcka brunst hos mjölkkor genom visuell observation. Detta leder till ekonomiska förluster, minskat genetiskt framsteg, högre inkalvningsålder och längre kalvningsintervall. För att underlätta brunstregistrering i besättningarna finns olika automatiska registreringar som kan upptäcka fysiologiska eller beteendemässiga förändringar som framträder hos kon vid brunst. Denna litteraturstudie sammanställer tre olika principer för brunstdetektering; visuell brunstdetektering, stegräknare och bestigningsdetektor, som kan vara antingen elektronisk eller manuell. Resultatet visar att stegräknare är den metod som upptäcker flest brunstperioder medan visuell observation ger minst felaktigt detekterade brunstperioder.
Spelutveckling och lansering av applikation till Android
For several years Uppsala University together with several companies has been involved in a WISENET project aimed at improving railway transport security. By placing a sensor system near the wheels of each wagon, the temperature of the bearings can be measured and transmitted to a collector placed centrally on the wagon. This in turn transmits the collected data to RFID receivers placed intermittently along the railway.As the signals are transmitted wirelessly, problems may occur as the antennas get dirty or coated with ice and snow. To determine the effects of these coatings, several tests were performed examining the reflection coefficient S11, the impedance Z11 and the efficiency eta of an antenna, and how they varied when various coatings were placed over the antenna. Examined coatings were ice, snow and water to determine the effects of weather, and various metal-based coatings: powdered iron both pure and partially oxidized, and iron ore granules.
Högstadiepojkars reflektioner kring val av fotbollsprofi : Med särskilt fokus på elever med utländsk bakgrund.
I denna studie har vi undersökt hur 10 högstadiepojkar med utländsk bakgrund reflekterarkring sitt val av fotbollsprofil. Vi genomförde semi-strukturerade intervjuer och analyseraderesultatet utifrån Bourdieus begrepp habitus och kapital.Respondenterna i studien hade alla en utländsk bakgrund och majoriteten hade föräldrar sominte var födda i Europa. Nästan samtliga respondenter berättade att de bodde i segregeradeområden. Uppsatsen kommer fram till att respondenternas uttalade motiv till valet av att sökasig till och delta i fotbollsprofil under skoltid var bland annat för att de tyckte om att spelafotboll. Men även en annan faktor var att de via den utökade träningsmängden i skolan kundeförbättra sina förutsättningar att lyckas som fotbollsspelare.
Klimatskärmens funktion : En jämförande analys av projekterade nybyggnationer i Östra Salabacke, ur ett energi- samt fuktperspektiv
The design of the building envelope affects the energy consumption of a building. As the energy requirements for new buildings are becoming more demanding, the performance of the building envelope must be improved. Energy efficiency and durability are important attributes to consider.This report includes investigations of the building envelope, moisture and passive solar energy. It is based on the analysis of two different buildings with different designs. These buildings stand as reference for two of the companies who are working on a new, climate smart, residential area in Uppsala, Sweden.Studies and analyses on energy consumption and moisture transportation were made.
Att fånga kunskap och erfarenhet
Att ta tillvara på de erfarenheter och kunskaper som genereras i enorganisation är något som, enligt oss, bör ses som en självklarhet. Vårt syftemed uppsatsen är att ge Siemens Enterprise and Communication AB (SEC)en teoretisk referensram på hur man gör detta, samt att vi som författareskaffar oss en djupare förståelse för detta problem.SEC är en ganska nybildad organisation då de för inte allt för längesedanbröt sig loss från kontoret i Köpenhamn och skapade ett eget kontor iMalmö. På grund av att deras organisation är så pass ny har SEC uttryckt ettintresse om vad teorin säger om erfarenhet och kunskap inom organisationer.Vi har intervjuat tre avdelningschefer på företaget för att få en bild av derasnuvarande arbete med kunskap och erfarenhet, samt vad de har förförhoppningar på framtida kunskaps- och erfarenhetshantering.Då vi tycker att Knowledge Management (KM) är den teori som liggerproblemet närmst om hjärtat är det utifrån den vi valt att bygga vår uppsatskring. Till hjälp har vi valt att använda en berättelse om hur det kunde ha gåtttill när SEC implementerar KM i sin organisation. Berättelsen hjälper till attbelysa problemområdet samtidigt som den avslöjar hur organisationen äruppbyggd.Uppsatsen kommer inte visa någon färdig mall för hur erfarenhets- ochkunskapshantering skall gå till utan tenderar snarare till att, med hjälp av ennarrativ ansats, lyfta fram de punkter som KM litteraturen håller somviktigast..
Förbättrad muskelfunktion och balans hos äldre kvinnor efter sex veckors funktionell träning
Sweden is the country that has got the largest amount of elderly in the adult population in the world. The physical activity level decreases as we grow old and we experience muscle mass loss and a bone density reduction. This leads to an increased risk for falls and subsequent fractures. The purpose of this study was to investigate whether an exercise program could affect muscle function and balance ability to prevent falls. 17 women (age 64-79) participated in this study and was assigned to a control group (n=7) and an intervention group (n=10).
E-handel och tillit : En kvalitativ studie om fo?retags och kunders perspektiv pa? tillit
Statistics indicate an increase in online shopping. This indication could result in the loss of safety factors for the customer, for example the possibility to physically examine the product, interact with professional store personnel and try the product before purchase ? factors which all could support the customer in her choice of company and product. The purpose of this study is to increase the theoretical knowledge regarding strategies in the area of trust-development between customers and companies. We have chosen to investigate what strategies web based companies apply and how they are perceived by their customers.
Evaluation of Lactobacillus reuteri DSM17938 as starter in cheese production
The probiotic bacteria Lactobacillus reuteri DSM17938 was evaluated as a starter culture in cheese production, with the intention to produce a new interesting product within the functional food market. Growth and acidification rate in milk subjected to different heat treatments, as well as supplementation with growth promoting factors or support cultures was measured during controlled fermentations. The results showed that the weak proteolytic activity of L. reuteri could be compensated for by supplementation with 1% casamino acids or 5% MRS broth. Furthermore, a decrease in growth and acidification rate could be seen when using yoghurt culture or Lactobacillus delbrueckii as adjunct cultures.
Forsmark 3 ?Ett Framtida Biobränslekraftverk?
Recent turmoil surrounding nuclear power as an energy source, especially since the accidentat Fukushima, has largely contributed to the debate of whether or not nuclear power should beused as an energy source. This study has examined the economic feasibility of replacingForsmark?s 3rd nuclear reactor with a bio fueled power plant, and find out how this could bedone.The power generation that has to be replaced is equal to 1170 MWe. To replace this, 6 largescaleCFB-boilers, each providing over 200 MWe, were necessary. In addition to this, eachboiler required their respective turbine sets, comprising one high-pressure-, and one lowpressureturbine with intermediate reheating capacities.Based on this, a rankine-cycle was modeled using the software EES, to be able to calculatethe total heat required in the power plant.
Assuandammens påverkan på Nilen, Egypten
Regulation of rivers by dams and reservoirs is a good example where anthropogenic impact could be considerable both in the local environment, but also has major implications upstream and downstream. This study was accomplished as a literature study of the river Nile, which is extremely important for water supply. The purpose of this study was to investigate the consequences of the construction of the Aswan High Dam, to obtain a consistent flow for water supply, irrigation and power generation in Egypt. Since Egypt has a very hot and dry climate large amounts of water in reservoir is lost to the Nubian aquifer system and by evaporation. The consequences from constructing the dam are considerable.
