Influence of prescribed burning and/or mechanical site preparation on stand stem density and growth of Scots pine stands above the Arctic Circle : results 9-19 years after stand establishment
Prescribed burning was commonly used for site preparation in Sweden to establish new forests until the 1960?s, when mechanical scarification was introduced. During recent decades the interest in prescribed burnings has increased again, mainly due to certifications of forestry stating that 5% of the regeneration areas should be burned on dry and mesic soils.
The objective of the study was to evaluate actual influence of prescribed burning compared to other site preparation on stand stem density, growth parameters and tree damages for Scots pine (Pinus sylvestris L.) after direct seeding and planting. The study also attempts to simulate growth until first thinning.
Konsten att förutspå konjunkturen - Hur användbara är enkätbaserade snabbindikatorer?
Foreseeing future changes in economic activity is of up most importance to a wide array of actors. The time lag in the presentation of official GDP statistics means that to somewhat accurately capture a tendency of where the business cycle is heading one need turn to qualitative sentiment indicators such as Purchasing Managers? Index (PMI) and official sentiment indicators for valuable clues. This thesis uses in-sample and out-of-sample methods to evaluate how well PMI and official Business Tendency Surveys (BTS) in Sweden and Denmark fair against the year-on-year Growth rate of industrial production. Moreover, various Swedish regional sentiment indicators get examined and a case study of the indicator for the Öresund region is performed.
Tungmetaller i lakvatten : avskiljning med mineraliska filtermaterial
Four different kinds of filter-materials with reactive surfaces have been studied concerning their capacity to absorb heavy metals in leachate from a municipal waste deposit. The heavy metals studied were: lead, cadmium, copper, mercury, chromium, nickel and zinc. The leachate contains high levels of dissolved organic carbon (DOC) and has a high pH-value along with a high buffer capacity. These characteristics of the leachate make it difficult to remove pollutants and require efficient filters. The filters that were examined in the report are blast-furnace slag with CaO, sand covered with iron oxides, olivine and nepheline.
Wii Sports och Sport : En jämförelse av fysiska och emotionella skillnader och likheter i träningsspel jämfört med riktig träning
AimThe purpose of this study is to compare the level of activity between playing wii Sports Tennis and wii Sports boxing, and the usual sports, and to see how the two variants are perceived.Issues:- How much strain ratio and energy consumption it gives to exercise wii sports compared with the playing of sport for real?- How do the test participants experience the different tests?- How are the two wii sports games against each other in terms of activity and fitness in the school environment?MethodThis is an experimental study in which 10 test participants (5 men and 5 women) have carried out four different physical tests. The tests consisted of either playing an exergame or playing a sport for 25 minutes. Physical activity was measured during the test using a heart rate monitor. All test participants completed all tests in the same order.
Vem styr bostadsbyggandet i Nacka och Södertälje? : Vilka aktörer påverkar slutresultatet?
Who runs the development? A comparative study of the construction of residential buildings in Nacka and Södertälje.The aim of this study is to identify actors involved in the initiation and implementation of residential house construction in two Swedish municipalities. This means who is taking initiative for new residential buildings, who affects the planning process, who finances these new buildings and who builds them. By exploring empiric material from the municipalities of Nacka and Södertälje, the above questions will be answered and by referring to pluralism, growth machine theory and regime theory a link to general theories of political science is made. The results found show that the analysed municipalities have quite different possibilities for acting and that these backgrounds are also important for which actors will take initiative for new residential buildings and which actors will be allowed to state their opinion during the planning process.
Effect of vortex-processed water on tomato (Solanum lycopersicum) plants
This pilot study examined whether treatment with Vortex Process Technology (VPT) of the irrigation
water used on tomato (Solanum lycopersicum) plants had any effect on plant growth. In a block
experiment, with two blocks comprising 12 vases containing 1 L water and two tomato plantlets,
treatment in which, nutrient solution was based on Vortex-treated water was compared with an control
using untreated water. All vases were kept in a static aerated culture system in a daylight chamber for
four weeks. The results showed that the effect of the two blocks exceeded the effect of vortex
treatment in terms of leaf area and weight of fresh and dry matter. Plant height, stem width and
internodal length were significantly different in tomato plants grown in Vortex-processed water
compared with the untreated control.
Kaninen som produktionsdjur
The purpose of this report was to obtain an overview of rabbit meat production in the world, in terms of breeding and feeding. It examines how different feed components contribute to the health of the rabbit as well as the quality of the carcass, and the breeding strategies that are most common in the major producing countries. The production of rabbit meat in Sweden is at present not very large, but it is gaining ground, and that is why this paper mainly deals with the rabbit production abroad. This report also examines the disease Rabbit Viral Haermorrhagic Disease (RVHD) in Sweden, where this disease can cause big problems.
The rabbit (Oryctolagus cuniculus) is very special, both in its reproduction and digestion. There is no specific mating season and the digestive tract is designed to digest forage efficiently.
Kvickrotens reaktion på klippning och konkurrens i rajgräs- och vitklöverbestånd :
Couch grass (Elymus repens (L.) Gould) is a severe weed in Sweden, and since both the use of herbicides and cultivation should be decreased, it will become increasingly problematic to control couch. The present work is meant to, by literature studies and an experiment, give some answers to the question if cutting and competition can depress the growth of couch. The experiment was carried out in the growing season 2001 at Ultuna, Uppsala, in plastic boxes. The design was three-factorial randomised complete blocks. The factors were plant combination, nitrogen level and cutting strategy.
Påverkas röstkällans egenskaper av förändrad stående kroppshållning? En experimentell studie av otränade mansröster
The aim of this study was to investigate whether a direct shift inpostural alignment results in changes in voice source characteristics. Ninemales with untrained voices were recorded standing in ideal posturalalignment and in the deviant postures swayback and kyphosis characterizedby extended hips and a slump back respectively. The voice source wasderived from the audio signal by inverse filtering. The parameters pulseamplitude, maximal flow declination rate, level difference between the firstand second voice source partials, closed quotient and the normalizedamplitude quotient in relation to subglottal pressure were compared betweenideal postural alignment and swayback and kyphosis respectively. Resultsindicate an impact of changed postural alignment on the voice source.Swayback posture gave significantly less pulse amplitude and maximal flowdeclination rate and significantly higher subglottal pressures thus resulting ina less effective phonation.
Feromoninnehållande substansers effekt på hjärtfrekvensen hos kvigor i östrus och diöstrus :
With increased milkproduction in our dairy cattle, comes a risk for a reduced fertility. Studies performed on animals and humans have shown that it is possible to manipulate the oestrous cycle through exposure to pheromones. This means that pheromones could potentionally be used to make reproduction more efficient. To evaluate the bioactivity of the substances in question, there is need for a bioassay. In insects, pheromones can induce a changed cardiac activity.

The challenge for technology is the social as information and knowledge requires. To believe blindly that technology will solve the problem is what many people think. In order to understand how technology can support information and knowledge management one needs to understand what information and knowledge is.
Empirisk studie av Indiens tjänstesektor - Vad händer med jobben?
The fast growing economy of India has experienced fundamental structural changes in recentyears. The share of the service sectors output has more than doubled since 1950 and is todayestimated to make up almost 60 percent of India?s total output. In terms of total employmentwe have not yet seen a similar transformation. The observed discrepancy between sectorialshares of employment and output in the service sector raises questions about sustainability.This report aims to investigate the capacity of the Indian service sector in terms ofemployment creation in order to answer the question whether the recent GDP growth withinthe service sector can be considered as ?jobless? or not.
Knowledge and focus, a condition for continuing sales growth
Problem discussion:
To be competitive in a changeable environment, as the video surveillance market, in a time when the company and the market grow with almost 40% yearly, the sales organization must be well trimmed and effective. Knowledge about customers’ needs and what makes success are essential parts of the progress. Sales Product Management (Sales PM) is a new group at Axis with the main task to support local sales offices around the world in their work with different sales projects. Because of the number of ongoing projects Sales PM needs to be able to screen among these and focus on those where their help will be most valuable for the company. At the same time they have to know which kind of support their sales offices want and need.
Fast etableringsställe : En skatteplanerares dröm?
This master?s thesis will examine the concept of ?fixed establishment? in VAT-law. The concept can be found in the new EC-directive on the common system of value added tax, however it has existed for thirty years in previous directives. Despite this, the legislator has never provided a proper definition of the concept. Its meaning has therefore evolved through the case-law of the ECJ.The Court has put forward a number of criteria which are all to be met if a fixed establishment is to be at hand.
Arbetslöshet bland utrikes födda på den svenska arbetsmarknaden : En empirisk analys av vilka kommunala faktorer som kan påverka den höga arbetslösheten bland utrikesfödda
Unemployment amongst Swedish citizens is higher within the group which falls under the designation foreign-born. The aim of this thesis is to examine which municipal factors that can explain the differences in unemployment amongst foreign-born relative to native born.The empirical models are examined with both cross-sectional data for the year of 2010 and panel data for the years of 2002-2012. The examination is implemented through a linear regression analysis of the type Ordinary Least Squares (OLS) and Fixed Effect regressions. A theory section will be presented where the theory on Non-Accelerating Inflation Rate (NAIRU), theories on discrimination and country-specific human capital are illustrated.The result from the cross-sectional data shows that the amount of foreign-born, the level of foreign-born immigrated from Nordic countries have a significant negative effect on unemployment amongst foreign-born. The general unemployment shows a significant positive effect on the unemployment amongst foreign-born.
