Grundvattensänkning till följd av järnvägstunnel genom Hallandsås : miljökonsekvenser relaterade till förändrad kväveomsättning i mark

This thesis was carried out to give some background information to a report of SLU (Swedish University of Agricultural Sciences) for the Swedish National Rail Administration (Banverket). The requested information was to provide basic data for an environmental impact assessment of the construction of the tunnel through Hallandsås. The aim with the thesis work was to discuss and quantify the leaching of nitrate and the emission of nitrous oxide from the soil at the groundwater level established through the tunnel project. The nitrogen related processes that could be affected were described and discussed. The different areas where a decreased groundwater level can cause changes in the nitrogen processes are the wet and moist areas.

Skolkvalitetens lokala bakgrunder : -En explorativ fallstudie av fyra svenska kommuner för att kartlägga anledningar till deras olika placering i lärarförbundets undersökning ?Bästa skolkommun 2011?

This study begins in a previous benchmarking study made by one of Sweden?s teachers unions Lärarförbundet. This is a statistical study that ranked the Swedish municipalities against each other?s according to their accomplishments in a number of areas related to their school systems.

Krubbitning hos häst : implikationer på djurvälfärd och argument för en nollvision om förekomst av beteendet

Most descriptions of stereotypic behaviours have in common that these repetitive behaviours only has been observed in captive animals and therefore it has been proposed that stereotypies exist because we house animals in environments that are sub-optimal to them. Some scientists claim that performance of stereotypies in itself decreases the animal's welfare due to costs in time, energy and health and a poorer quality of life. Other scientists assert that individuals performing stereotypies may have a better welfare compared to the rest of the animals in the same environment, since these individuals have developed strategies to cope with stress. Studies have estimated the prevalence of abnormal behaviours in horses to 18-30 % of the population. Several studies on cribbing have revealed a prevalence of 4-5 %, although some results indicate that more than 10 % of the horse population performs this stereotypy.

Att ha en förälder med cancer : En litteraturstudie om ungdomars reaktioner. / To have a parent with cancer: A literature review about adolescents reactions

För ungdomar som är mitt uppe i frigörelseprocessen från föräldrarna kan det vara en känslomässig balansgång när en förälder insjuknar i cancer. Det är viktigt att denna oro uppmärksammas och bekräftas för att inte ge långsiktiga negativa konsekvenser. Syftet med litteraturstudien var att belysa ungdomars reaktioner när en förälder har cancer. Studien genomfördes som en allmän litteraturstudie. Nio vetenskapliga studier inkluderades i resultatet.

Interna flöden och processer på Å&R Carton : processbaserad verksamhetsanalys och förbättringsförslag för ledtidsreduktion

Denna rapport syftar till att, på Å&R Carton i Norrköping, analysera de interna flödena och processerna samt ge förslag på hur ledtider ska kunna reduceras väsentligt. Ett sätt att uppfylla syftet är att dela in verksamheten i processer genom olika metoder och kriterier förprocessbestämning. Valda metoder i rapporten är; kvalitativ ansats med hög validitet och reliabilitet, processbaserad verksamhetsanalys och procedurbeskrivning. Genom omfattande litteraturstudier, insamlande av data i form av intervjuer, benchmarking, platsundersökningar och interna dokument har nulägesmodeller arbetats fram. Analysen av dessa visar bland annat på att såväl planeringsprocessen som inköpsprocessen idag inte fungerar värdeadderande och bör ses över.

Vilka faktorer påverkar ett mjölkföretags tillväxt? : en jämförelse mellan Sverige och Danmark

Dairy farms have during a long time been under pressure and this situation was aggravated during the spring and summer of 2009, when profitability declined to historically low levels. Lower milk price and relatively high input prices have caused Swedish dairy farms great liquidity concerns and profitability problems. For a long time, Denmark has been identified as a leading country for the agrarian development with a leading structural rationalization and willingness to grow. In 2009, it was shown that the Danish agriculture, which is generally more leveraged, has difficulties in maintaining profitability and when market price of land started to fall, the proportion of technically insolvent agricultural enterprises rose dramatically. In light of this prevailing situation, this study highlights differences between Denmark and Sweden with the hope to learn from each other.

Virtuell hållfasthetsprovning av en turistbuss

The competitive nature of the automotive industry has always implied a necessity to improve product development concerning time-to-market, cost and product quality. As capacity of computer-aided engineering (CAE) tools has evolved, so has the strive for simulation-driven design. Virtual durability testing using full vehicle models is one of many challenges posed in front of vehicle manufacturers when computer simulations are given a key role in product development.This thesis has been initiated as a preliminary step towards implementing dynamic virtual durability testing in the development of buses and coaches at Scania. The objective has been to assess the predictability of a full vehicle coach model and to what level of precision structural loads can be predicted. Previously performed proving ground testing of a Scania Touring coach has been the basis for the modelling and simulations in this thesis.A virtual model of the Scania Touring coach has been created in multi-body simulation software package MSC.Adams.

Likvärdig service börjar med ett gott bemötande: folkbibliotekens beredskap inför 2010.

In 2010 there will be a political resolution to ensure that the Swedish society is accessible to all citizens including people with disabilities. For this purpose a national action plan for disability policy "From patient to citizen" (Govt. Bill 1999/2000:79) has been set out with the aim of ensuring that the disability perspective will permeate every sector of society and that the approach and response to people with disabilities will be improved. The Swedish National Council for Cultural Affairs is responsible for implementing the disability policy in the cultural sector.Since public libraries in Sweden are a part of the public cultural sector, they will also be affected by the political resolution regarding accessibility. The concept underpinning library services for disabled people must be that of equality of access.

Vedrötor i stadsträd : biologi, detektionsmetoder och förebyggande åtgärder

Urban trees have very little in common with trees on natural sites, such as forests or pastures. Trees in urban environments are often planted in packed soil and in small volumes. This can lead to decreased availability of water and oxygen, as well as deteriorated ability for the soil to store nutritional elements. Also above ground the tree usually have limited space in cities. Regulations on free height over roads and cycle tracks demands high stems at an early stage of their development.

Implementation of renewable energy in the Republic of Moldova : society and landscape in transition

The Republic of Moldova, situated in eastern Europe and a former part of the Soviet Union, is now experiencing a phase of transition in both society and landscape. They have hardly any fossil depots and are currently dependent on Russian gas, with 97% of their energy needs imported. The new elected government wants to move towards the EU and this is generally seen as the way to grow and reduce poverty. Security in the energy sector is important and one tool is to increase the use of renewable energy sources. Through interviews, texts, and visits I have studied the implementation of renewable energies (RE) in Moldova through a society development perspective. The study has aimed to investigate the sociotechnical complexity of this subject and to discuss the potentials and way of dealing with the subject in the specific cultural context of Moldova.

Canine S- and M/L- cone electroretinograms

Full-field flash electroretinography is an electrodiagnostic method used to examine the function of retinal cells. Light stimulation of the eye elicits electrical potentials in the retina. By aid of a corneal electrode and a reference electrode close to the back of the eye, the electrical potentials can be recorded and presented as an electroretinogram (ERG). ERGs driven by mainly one type of cones can be used to examine the function of a single cone class. In human beings, studies have shown the cone class sensitive to light of short wavelengths, the S-cones, to be more vulnerable to acquired damage than the other cone classes (Daley et al., 1987; Gouras et al., 1993; Greenstein et al., 1989). Dogs have two cone classes, S-cones, and M/L-cones (most sensitive to medium to long wavelengths).

Optimerad höstveteetablering : en litteratursammanställning om såtid, radavstånd och utsädesmängd

This bachelor thesis is intended to gather the knowledge and experimental data on the winter wheat crop production relevant for Swedish conditions, with focus on sowing time, row spacing and seed rate. This essay is a literature study with a minor component based on interviews with farmers producing winter wheat. The work is divided into a background part where basic knowledge of winter wheat physiology, development and environment interactions are described and one part where results of field trials studies are presented. Optimal date of sowing winter wheat depends on annual weather variations. Because it is difficult to forecast the weather the choice of sowing date should be based on weather statistics, production experience and previous results depending on sowing date.

Utveckla eller avveckla : varför väljer vissa av Milkos medlemmar att utveckla sin mjölkproduktion medan andra avvecklar?

The Swedish dairy sector is facing several challenges the coming years. One big challenge is how they will secure the access of their raw material milk in the future. The number of milk producers has decreased for an extended period of time, but was for a long time partly compensated by an increased productivity among the remaining milk producers. From year 2000 that trend was broken and also the quantity of milk produced started to fall quickly. Milko is a dairy company with members from Dalsland in the south to Jämtland in the north. During the first seven moths 2007, their number of members decreased by almost a fourth, from 1 272 to 974.

Svampar associerade med raps : betydelse för uppkomst och grödetablering

Oilseed rape is an important crop in Sweden and is grown on about 90000 ha today. The interest in oil seed pro-duction is increasing because of growing demand and high prices for oil seed both in Sweden and Europe. However, an increased intensity in the oil seed production can bring higher risk of yield losses due to fungal diseases. The purpose of this study was to investigate what different fungi are associated with oilseed rape under field conditions and if their incidence is correlated to crop establishment problems. This study was carried out in three parts: 1) investigations on fungal community structure in roots and rhizosphere soils from young spring- and winter rape plants sampled in failed respectively good establishment patches in four fields, 2) investigations on the pathogenicity of fungi isolated from oilseed rape in controlled environment and 3) investigations on the effect of different fungicide seed treatments on germination and early plant development in a field soil naturally infested with damping off- and Verticillium wilt pathogens. The studies on community structure using a combined approach of standard fungal isolation techniques and DNA based methods revealed a high fungal diversity in three out of four studied fields of spring rape and winter rape. For some unknown reason, very few fungal species were identified from the fourth field.

Kunskap om och attityder till dopning bland styrketränande unga vuxna : En kvantitativ undersökning i Mellansverige

The main purpose of this study was to determine the self-estimated levels of knowledge about doping for a group of strength training young adults, and also to get an idea of their attitudes regarding the subject. A part of the purpose was also to investigate the potential associations between knowledge and attitude. Method: To collect information a questionnaire was constructed that was inspired by a similar study and in consultation with the tutor. Questions regarding background, doping and training experiences together with self-esteemed attitudes and knowledge about doping were included. Questionnaires were handed out at gym facilities in central Sweden, and were answered by men and women ages 18 to 35 years.
