Röjningsbenägenheten bland privata skogsägare : en enkätundersökning bland medlemmar i SÖDRA

The intensity of cleaning declined dramatically in the early 1990?s in the Swedish forests. Recession, an economic depressed forestry and the new law of silviculture from 1993, where the duty of cleaning was removed have been considered as sources to the decline. This has led to a situation where huge areas of forests are untouched, which can lead to negative effects for those stands in the future. The purpose of this thesis was to find out how the individual landowner acts and feel when it concerns cleaning activities. Has the landowner noticed Södra?s campaigns about cleaning and what sort of measure should Södra implement to increase the members? cleaning activity? The thesis is based on a opinion poll made through a random draw among all Södra?s members.

Livscykelbaserad miljövärdering av en ny kontorsbyggnad : En jämförande studie mellan två analysmetoder

This Master?s Thesis aims to illustrate in what ways the two Swedish environmental assessment tools, the Environmental Load Profile and EcoEffect differ and if performed valuations gives different results and environmental goals.The built urban environment causes about half the environmental loading in Sweden. The society?s ambition towards sustainable development has resulted in demands reducing the environmental load. One way to accomplish this change is with the assistance of tools for environmental assessment of the built environment.

Doby?ins fokus : Detaljerna och debatten om Gud i ?urkina rodnja

Nathan Söderblom, Swedish archbishop 1914 - 1931, understands his role as bishop from an integrated theological conception that episcopacy is a gift to the church and the apostolic succession a heritage of utmost value. Episcopacy is an important tool to make the churches come together. in his work for peace during the Great War it was through his position without any power that he could approach the politicians. His calling was not only for Sweden; he had a responsibility for the whole world. In the Ecumenical Cope for the 1925 Stockholm meeting Söderblom expressed his views on the importance of the Uppsala see.

Från Skiss till Diss

Over the past decade, the fashion industry has experienced a relatively high rate of consumption with material and clothing becoming increasingly subject to waste and disposal. As a result of the increased awareness within the industry the interest in CSR (Corporate Social Responsibility) amongst retailers has increased substantially in an attempt to shy away from the critically amplified media attention. In addition the underlying demand from external stakeholders has forced companies to ensure they focus and act upon each stage of the product life cycle.This study provides a further in depth analysis of the fashion industry and conveys the key messages and steps that firms are taking in response to the external pressures and requirements based on four different merged process areas. This research paper examines the impact of CSR on two Swedish fashion retailers Åhléns and JC and shows how accountability relates to the external expectations and norms that prevail in society. The result shows that the firms do meet the demands within each sub category as a response to market demands.

Thymidinkinas 1 som tumörmarkör vid juvertumörer hos tik :

Determination of serum thymidine kinase 1 (TK-1) activity is used as a tumour marker in both human and veterinary medicine. TK-1 is an intracellular enzyme involved in a salvage pathway of DNA synthesis. The expression of TK-1 is cell cycle dependent and the activity increases markedly after the G1 to S transition in the cell cycle and then declines rapidly in G2. The pronounced proliferative activity in tumour cells result in a higher TK-1 enzyme activity within the cell. The fact that the increased TK-1 activity can be measured in serum makes TK-1 a useful marker in diagnostics of neoplastic diseases and it provides information regarding prognosis and treatment effectiveness. In human medicine a radioactive based test is used to determine the TK-1 serum activity.

ESC-analys och studering av knack på en "Diesel Dual Fuel"-motor

A one-cylinder research engine has been used for studies with a Diesel Dual Fuel concept (DDF). DDF is a concept that utilizes a pilot diesel injection to ignite a homogenous natural gas/air mixture. Emissions and engine efficiency have been analyzed in an emission cycle called European Stationary Cycle (ESC) and the knock/pre-ignition problems with this type of engine have been investigated.At low and mid torque levels, an early diesel injection around 60 crank angles degrees (CAD) before top dead center (TDC) was used. At these loads raw NOxemissions was below EURO 6 level (0.2 g/kWh). NOxwas at EURO 5 level over the complete ESC without after treatment and with SCR at high loads it should be possible to reach EURO 6.One issue with DDF is the high HC emission levels.

Validering av Casmo-5M / Simulate-3

The objective of this M. Eng. Diploma work was to validate the new version, CASMO-5M, and compare the results with CASMO-4E, by using the same input in both programs. The tasks that were included in this work was to compare TIP-measures, k-effective curves (warm), k-effective curves (cold), the effect of void on k-effective, the isothermal temperature coefficient (ITC), the moderator temperature coefficient (MTC), damping ratio calculations, internal effect in a fuel bundle of a BA-rod, the speed of BA-out burn, impact of xenon, falling control rod, margins and isotopes.The TIP-measures showed that the differences were small for all reactors, at most, 6% nodal improvement by C5M (Casmo-5M) for Oskarshamn 3. The warm measurements of k-effective showed that C5M had a higher value for all cycles of Oskarshamn 1, 2 and 3 in comparison to C4E (Casmo-4E).

Are changes in heart rate and/or arborisation of vaginal mucus useful parameters for detecting heat in heifers? :

The milk production per cow has increased considerably during the last 50 years and due to the breeding for higher milk production also brings decreased reproduction efficiency. In a Swedish study 1996 it was shown that on average only half of all estruses were detected. Every time a farmer fails to detect oestrus it costs the farmer about 1200 Swedish crones and the need of means of detecting oestrus is therofore large. With this study we wanted to investigate if heart rate respectively crystallisation of vaginal mucus (arborisation) could be useful means of detecting oestrus. We monitored two oestrus cycles in four heifers.

Kvinnors preventivmedelsanvändning under olika faser av det reproduktiva livet

Introduction: Studies have shown that women are not always satisfied with the effects of contraception and that contraceptive advice is perceived as non-specific. Aim: The purpose of this study was to investigate what contraceptive women have chosen to use in the different phases of their reproductive lives, and what they felt had influenced their choice. Method: A retrospective cross-sectional comparative study with a quantitative approach. A survey with fixed and multiple-choice options was sent to five hundred 45-year old women. Result: The study shows that various birth controls are different in the normal reproductive life.

Anpassning och optimering av checkprogram för AW139

Presently Sjöfartsverket do their maintenance according to a standard program, which means that every maintenance task will be done when the task limit occurs. This leads to a very long downtime for the aircraft in some occasions and very short downtime in others. The goal with this work is to reach a higher regularity of the aircraft operation. To reach a higher regularity for the operational needs, this work will present a hypothetic better maintenance concept for Swedish Maritime Administration. The concept is based on equalized maintenance structure, which means that every maintenance occasions are meant to take the same time to perform.

Brunstvisningsförmåga hos SRB- och Holsteinkvigor

Oestrus in dairy cattle has changed over the last decades, the duration has decreased and the intensity of oestrus has declined. A possible explanation can be their high and increasing milk production. Heifers ability to show oestrus is probably not affected to the same extent. The aim of this study was to estimate and compare oestrus duration and strength in heifers of the Swedish Red and Holstein breeds. Standing oestrus has been the primary oestrus sign during many years.

Garantier kontra due diligence vid företagsförvärv : Särskilt om säljarens och köparens ansvar

SammanfattningAv störst vikt vid en företagsförvärvsprocess är huruvida säljaren och köparen reglerar sina ansvarsområden och bestämmer gränser för riskövergången i köpeavtalet. Ur rättsäkerhetssynpunkt är det essentiellt att kunna förutsäga och identifiera riskerna redan vid avtalsslutet. Det ligger ofta i parternas intresse att så långt som möjligt reglera förutsättningarna redan vid ingående och utformning av ett köpeavtal.Syftet med denna uppsats är att undersöka samspelet och följden av att säljaren inför garantiutfästelser i ett köpeavtal kontra resultatet av att köparen faktiskt genomför en due diligence-undersökning innan ett köpeavtal kommer till stånd. Detta genomförs med utgångspunkt i diskussionen kring riskfördelning mellan avtalsparterna, köplagens regler om säljarens upplysningsplikt, köparens undersökningsplikt och den allmänna lojalitetsplikten som åligger avtalsparter.Utgångspunkten vid formuleringen av avtal mellan parterna anses vara det köprättsliga felbegreppet med dess utgångspunkt i köparens befogade förväntningar på det överlåtna objektet. En genomförd due diligence och införande av garantier i köpeavtal kan innebära att riskövergången regleras och de befogade förväntningarna preciseras vilket leder till förutsägbarhet och säkerhet för parterna att kunna förutse eventuella framtida risker.

Investigating the reward cycle for play in young pigs

A reward cycle for investigating the emotional status in animals has been developed and it requires that animals go through three main phases, i.e. anticipation, consumption and relaxation. The reward cycle has not been tested previously for access to play in pigs. Therefore, the aim of this Master thesis was to investigate if growing pigs showed more behaviours indicative of excitement than pigs that were not allowed to play, performed play in a play arena and showed more behaviours indicative of relaxation after play when they were back to their home pen than pigs that were in their home pen the whole time. Forty undocked piglets (10 litters of Specific Pathogen Free half pure-bred Yorkshire and half hybrids of Yorkshire x Landrace balanced for breed between two treatments were used.

MCNP-modell för beräkning av neutrondos och DPA på reaktortanken vid Ringhals 2

In this report an MCNP (Monte Carlo N-Particle) model is described for the reactor vessel at Ringhals 2. The model is validated against the specific activity in neutron dosimeters, extracted in 1977, 1984 and 1994. The validation showed that the calculations of the model are within the requirements of a maximum of 20 percent uncertainty for every neutron dosimeter except one, extracted after the first cycle. The uncertainty of this cycle was mostly due to the operation data rather than to the MCNP model.The model has been used to investigate various questions concerning radiation damage. The reliability of the traditional measure of radiation damage, fast neutron flux (En > 1MeV) has been evaluated.  This has been done by taking the ratio for this and another measure of radiation damage, DPA (Displacement Per Atom), for various positions and layers.

Arya och Nasuada?Sidekicks eller Hjältinnor? : En studie i personlighet och utveckling hos två kvinnliga karaktärer ur Inheritance Cycle av Christopher Paolini

Skuggor har länge fascinerat mig och varit en viktig del i mitt konstnärliga arbete. Skuggor av glas berättar inte bara om den yttre formen utan förmedlar även något från glasets inre. Mötet mellan det yttre och det inre, mellan det materiella och det immateriella är ett tema för detta arbete. Konsten och konsthantverket har en unik möjlighet att utforska och förmedla erfarenheter och kunskaper som finns i våra kroppar. Kunskap som vi ännu inte greppat med vårt intellekt.
