The information technique is developing at a fast pace and almost all new technique is being welcomed with opened arms. The newest on the market is the tablet device, it´s a device used for surfing the web, sending email, watching movies and playing games. It is now also being used in some schools for educational purposes. My research goal has been to find out how the teachers feel about using the tablet device for educational purposes. I have conducted interviews to find the answers to my questions.

Upplandsstiftelsen är en organisation med målet att gynna friluftslivet i Uppsala län. De förvaltar ca trettio naturreservat, rekreationsområden och Upplandsleden. Besökarundersökningar kan ge information som är användbar för att bidra till stiftelsens mål. Syftet med arbetet var att fram en plan för genomförande av upprepade besökarundersökningar på stiftelsens områden och leden. Planen skulle inkludera besökarstudier och besöksräkning.

A key part in the development and verification of digital systems is simulation. But hardware simulators are expensive, and software simulation is not fast enough for designs with a large number of gates. As today?s digital zesigns constantly grow in size (number of gates), and that trend shows no signs to end, faster simulators handling millions of gates are needed. We investigate how to create a software gate-level simulator able to simulate a high number of gates fast.

Bakgrund LCHF (Low Carbohydrate, High Fat) är en lågkolhydratskost som fått stort genomslag i Sverige. Svenska Livsmedelverket är oroliga för hur denna utveckling kommer att påverka folkhälsan, framförallt då kolesterolnivåerna i landet under samma period ökat. Förespråkarna av kosthållningen ställer sig däremot frågande till rådande rekommendationer och menar att det är dessa som gör oss feta och sjuka. Trots debatten fattas det data på hur en LCHF-kost faktiskt ser ut.     Syfte Syftet med denna studie var att kartlägga hur en LCHF-kost ser ut gällande livsmedelsval och näringsintag och utifrån det diskutera kosthållningen ur ett folkhälsoperspektiv.Metod 14 individer som ansåg sig äta enligt LCHF rekryterades till att utföra en vägd kostregistrering under tre dagar.

Bakgrund: Diabetes typ 2 (DT2) är ett ökande hälsoproblem och sjukdomen innebär att kroppen producerar mindre insulin än kroppens aktuella behov. Övervikt, fysisk inaktivitet, ohälsosamma kostvanor, ärftlighet och stigande ålder är riskfaktorer för att utveckla sjukdomen. För att undvika komplikationer ska ett stabilt blodsocker eftersträvas. Sjuksköterskan ska vara ett stöd och ge kunskap om egenvården, som enligt Orem innebär upprätthållande av hälsa och livskvalitet. Fettsnål kost har under många år rekommenderat.

The Master Thesis has been carried out in cooperation with Silva Sweden AB and the objective was to develop a new product concept within the product category for everyday exercise. The purpose of the thesis was to use and analyze methods and tools which aid creativity and concept creation in order to make method recommendations for future projects.During the thesis a number of customer needs were identified, which in turn were translated into 20 concepts. On a concept decision meeting a pedometer-based concept was chosen for development. The new pedometer is in addition to counting steps also able to measure and calculate the user?s total climbed height during a day and present this graphically in comparison to famous monuments or distances.

Peat  lands  are  a  great  potential  resource  for  increased  forest  growth  in  Sweden, there  are  approximately  6.5  million  hectares  of  peat  lands,  whereof  around  70% produce less wood than one m3sk/ha and year and are therefore classed as forest waste  land.  There  are  over  200  000  hectares  of  peat  land  that  is  already  drained and  wooded,  and  that may  be  suitable  for  fertilization.  Forest  production  on  peat soils  usually  requires  drainage  and  fertilization.  Dewatering  requires  ditching  the area, so that the roots can have access to oxygen. Nitrogen is often abundant in the peat but other nutrients; especially potassium is in short supply. The  purpose  of  this  work  was  to examine  the effects  of  potassium  fertilization  on the  growth  of  spruces  that  were  planted  on  drained  peat  land  and  how  different amount of fertilizers affects the growth. Potassium deficiency is strongly growth inhibiting, since potassium is important for substance  transport  in  the  tree.  Potassium  is  also  important  for  the  carbohydrate formation, and because increasing the sugar content of the cells constitutes a lower freezing temperature does potassium availability in the soil play a major role in the winter  resistance  of  many  species.  Potassium  is  not  found  in  any  organic compounds in the tree, but is present in cell and tissue fluids. A fertilization trial was started in 1978 in Siljansfors Experimental Forest. The plots in the experiment were fertilized with different amounts of potassium and one plot was  left  without  fertilization.  All  plots  that  were  fertilized  with  potassium  grew considerably better than the unfertilized plot. The difference in production between the unfertilized plot and the plot that received the most potassium was 7.2 m3sk/ha and year. The unfertilized plot can still be classified as waste land. The theoretical production capacity was estimated using a Swedish system for site quality  estimation  of  wetlands  after  ditching  (dikningsbonitering).  The  plot  with most  potassium  produced  after  fertilizationaproximately  in  level  with  theoretical estimations.  Key  words:  Peat  land,  Fertilization,  Ditching,  Growth,  site  quality..

The lack of housing in the Swedish metropolitan areas is today a well-known fact. This isespecially true for the region in and around Stockholm. Due to the large amount ofmunicipality-owned land within Stockholm municipality the area for many new housingprojects are acquired through land allocation. How much time this process of land allocationconsumes for a typical project is today not really known. Equally unknown is the exactoutcome of the process, i.e.

Swedish agriculture has gone through big changes in the latest 60 years. The farm sizes have increased, which has led to raised tractor and machinery sizes and therefore increasing problems with soil compaction. A method to reduce these problems is to implement controlled traffic farming, CTF. All field operations are then concentrated to specific tracks by using GPS guidance. The aim of this work was to study how the tillage regime, with or without CTF, affects the soil, with the main focus on macroporosity. In Säby close to Uppsala, and Alnarp close to Malmö, randomized block trials has been carried out, and the data has mainly been taken from these trials.

The use of combi-drilling during spring tillage has become very common in southern Sweden in recent years. Combi-drilling leads to fewer passes on the field and better plant nutrient utilisation. An example of a combi-drill is the Väderstad Rapid, which is very widely used in spring tillage in southern Sweden. The Rapid has separate fertiliser and seed coulters, which means that the draught requirement is relatively high. It thus requires large, heavy tractors, which compact the soil and are comparatively expensive to buy and run. A few years ago the Finnish combi-drill Tume Nova Combi came onto the Swedish market.

Vallfodret utgör basen i idisslarens foderstat. Innehåll av råprotein är relativt högt i vallfodret men idisslaren har svårt att till fullo utnyttja det. Idisslarens proteintillförsel består av mikrobprotein som syntetiserats i vommen och foderprotein som passerat onedbrutet genom vommen. Den sistnämnda proteinkällan är speciellt viktig för högavkastande djur. Problemet med vallfodret är att det innehåller en betydande andel råprotein som lätt fermenteras i vommen.

Bakgrund Idag är LCHF (Low-carbohydrate High-fat) en populär diet. Forskningen som finns inom området fokuserar mycket på viktnedgång. Därför är det intressant att undersöka kosten genom att analysera dess sammansättning och jämföra med rekommendationerna enligt Nordiska näringsrekommendationer (NNR).Syfte Utveckla fyra-veckors menyer för LCHF-kost samt en blandkost enligt NNR inför en RCT-studie. Undersöka om det finns risk för lågt intag av vitaminer, mineraler och kostfibrer enligt NNR:s rekommendationer för unga kvinnor (18-30 år) vid en LCHF-kost. Undersöka möjligheterna att uppnå rekommenderade nivåer av vitaminer, mineraler och kostfibrer med en blandkost enligt NNR:s rekommendationer för unga kvinnor.

In today´s forestry, assessments of needs for thinning are based on basal area measurements. This is an indirect measurement. The approach and the developed assessment tables are based on an assumed production forest, which implies that management proposals in stands that deviate from the basic model may be misleading. Since Walter Bitterlich in 1948 launched the idea of the relascope, several modifications have been developed for different purposes. In common is that all are based on a certain angle measurement principle.

The search for antibiotic compounds from the natural environment has been going on for seven decades, ever since penicillin entered the market and antibiotic treatments became routine. The evolutionary pressure put on the pathogenic microorganisms induced a rapid spreading of naturally occurring resistance genes, leaving only the option of finding new antibiotics to treat the resistant pathogens. Microorganisms have been extensively mined for their biosynthetic abilities to produce biologically active compounds. To date, more than 23 000 microbial natural products have been discovered. The Actinomycetales are ubiquitous bacteria that have been used for antibiotic discovery for more than half a century, and over 10 000 natural products have been identified from the order.

The objective of this work was to evaluate and compare three field methods for detection of mastitis, California Mastits Test (CMT), DeLaval cell counter DCC (DCC) and FMA2001 Farm Milk Analyzer (FMA2001). Furthermore, to investigate at what cell count level clinical symptoms of mastitis are seen, and finally to check if the clinical findings and cell counts could be related to bacteriological findings. DCC and FMA2001 are new analytic instruments to be used on dairy farms for detection of mastitis. CMT has been a widely used cow-side-test of milk quality in mastitis control efforts, but it cannot be used for estimating cell counts in scientific studies or investigations. Two hundred and eight quarter milk samples from 52 cows were analysed with DCC and CMT, and 168 of these samples with FMA2001. Microbiological examination was done on 38 milk samples with CMT scores of 4 and 5.
