Användning av rötrest från kombinerad etanol och biogasproduktion : en jämförelse mellan tre alternativ

Scandinavian Biogas is involved in the planning of a combined ethanol and biogas factory in Karlskoga, Sweden. Besides biogas and ethanol large amounts of digester residues will be produced, about 450 000 liquid tonnes residue (~7,3 % Dry Substance( DS)). The objective of this thesis was to investigate possible uses of the residue from the biogas production process ScandgasEthanol developed by Scandinavian Biogas, and to derive a methodological approach how to evaluate and compare handling systems. Three systems where proposed and compared in this thesis; spreading of the untreated residue as fertilizer (system 1), dewatering to a higher DS content to reduce transportation before spreading as fertilizer (system 2) and production of a solid fuel by dewatering and drying the residue (system 3). The general conditions for the proposed systems were investigated in terms of practical viability, economical aspects, environmental impact and energy inputs/outputs.

Återgång till fysisk aktivitet hos män efter en främre korsbandsrekonstruktion

 Background: Earlier studies show that 30-92 % of ACL reconstructed return to their pre-injury physical activity. It is not clear why some people do not return.Purpose: The purpose of this study was to investigate the return rate to pre-injury sport among ACL reconstructed men. Another purpose was to characterize those patients who return and those who do not.Metod: A Web-based questionnaire with questions about returning to physical activity was sent out during the spring of 2012 to 93 men who had undergone an ACL reconstruction 6-40 months earlier and who, after 6-40 months after surgery, were evaluated with validated strength tests and self-assessment outcome measures.Results: At 12 months after surgery 56 % of the subjects had returned to their pre-injury sport. If the criteria were set higher ?back to the same- or a higher level? 14 % had returned.

Evaluation of four methods for the assessment of joint swelling in dogs

Evaluation of joint swelling is an important part of the orthopedic examination and can be used to follow a patient?s progress during rehabilitation and therapy. Usually a swelling is assessed by palpating the joint but a more objective, but still easy to use, method would be preferable.This study seeks to increase the knowledge in veterinary rehabilitation by validating four different measurement tools (three recognized and one novel) for the assessment of elbow joint swelling: palpation, tape measure (circumference and figure eight measurement), slide caliper (craniocaudal and mediolateral positioning) and tonometer. This was achieved by calculating the inter- and intra-rater reliability and correlating the results from the different measurements with each other.The methods with best inter- and intra-rater reliability as well as good correlation among themselves were shown to be slide caliper with craniocaudal positioning, circumference and figure eight. Additional studies, with a larger and more diverse material, ought to investigate these methods further..

Identifikation av produktionsstörningar och obalanser vid tillverkning av golvskenor

Our report procedure identification of instability and disturbance in an automatic manufacturing line of processing and assembling of chair sliding rails at Sapas manufacturing department in Vetlanda.To obtain a stabile ground we have mapped the material flow to receive a comprehensive view and to visualise connections.We have examined cycle times at different stations in purpose to identificate bottlenecks. The result of our examination showed that the bottleneck of the line was the brush station. This leads to that the expected bottlenecks identificated by Sapa gets a delay time and by that a longer cycle time.Interruptions has a clear negative influence at the line performance so we have also assemble data through the operators report list and compiled these in order to find out the interruptions effect on the line. The outcome during our assembled period was that the reported interruptions corresponded about 30 percent of the total available production time. This has a clear negative effect on the line productivity and efficiency as we have calculated in order to get the present status..

The Swedish liming operation : a study about liming officers opinions about some aspects regarding ecology, economy and organization

This is a study about the Swedish liming operation and the Swedish liming officer?s opinions of some aspects regarding ecology, economy and organization. The study objectives was motivated due to the recent changes in manuals for the assessment of limed waters and the suggested changes in decision making and decreased budget for liming. Moreover the anthropogenic acidification effects on the ecology are in many ways complex. Furthermore it was made in order to gain knowledge about the liming officer?s opinions in order to improve the ability to meet their needs regarding the assessment tools and also to investigate if other things can be improved concerning the liming operation.

Neurointensivvårdspatientens förutsättningar för ett optimalt neurologiskt wake-up test : en observationsstudie

Background: Examinations with the intent to assess neurological functions and level of conciousness are common in neurocritical care, but the effect on the patient is not entirely researched.Aim: The purpose of this study was to describe the patient?s situation at the neurological wake-up test concerning the environment, nursing interventions and the possibility given the patient to become awake, and if these conditions affect the outcome of the wake-up test.Methods: A quantitative observational study took place at a neurocritical care unit, where 20 patients were observed from interruption of sedation to the neurological assessment, which was performed by a neurosurgeon or a specialized critical care registered nurse. Nursing interventions, environmental factors and physiological parameters were documented.Result: Twelve intervention varieties to control patients? physiological parameters were used. CPP > 80 mmHg was found in 90 % of observations.

Perceptuell bedömning av dysartri: jämförelse av detaljerad kontra övergripande analys

The aim of the present study was to compare two differenttypes of assessment of dysarthria to be able to conclude which methodmight be more suitable for use in research and in clinical practice.Five speech pathologists with extensive experience assessed 20different recordings of individuals with dysarthric speech using twodifferent forms, one more detailed and one designed for a more overallassessment. In the detailed form 30 aspects of voice and speech wereanalyzed. In the short form 5 overall aspects of voice and speech wereanalyzed. Six of the recordings were duplicated to serve forassessment intra-judge reliability for each form. The results show thatthere was a high correlation between the two forms and that theymeasures the same types of speech deviations although on differentlevels of details.

Meningen med livet : hur 15-åringar i en stor och en liten stad i Sverige ser på livskvalitet

There are many good reasons to ponder about what it is that makes life worth living. To observe and reflect on what it is that gives a person a good quality of life is arguably the essential core of social-work. The aim of this research was to investigate how 15-year old youths interpret quality of life. The key areas that we explored in order to meet the research aims were: what did the youths interpret as a good quality of life for a 15-year old and for an adult, how did they view their own quality of life, and did they think that the regional context (i.e. if one lives in a big city or in a small town) affects how one interpret quality of life.The studywas based on interviews with four boys and four girls.

Variation in fattening pig exterior, gait and weight gain in commercial organic herds

Pigs in Swedish organic production systems have been shown to have more findings of arthritis at slaughter, compared to pigs in conventional pig production. With this in mind a study was performed, to primary, investigate variation in exterior, gait and weight gain between sire breeds and, secondly, to investigate variation between herds, season, gender, age and assessment occasion on these recordings. Swedish commercial hybrids, crosses between Norwegian Landrace and Swedish Yorkshire were inseminated with either Hampshire or Duroc as terminal sire. All the pigs had known pedigree as each semen dose contained sperms from one individual boar. All piglets were individually tagged closely after birth, and exterior and gait assessment were performed at two separate occasions, early and late during the fattening period.

Livförsäkringsbolag: En studie av intressekonflikter mellan aktieägare och försäkringstagare

The purpose of this thesis is to examine the conflict of interest between shareholders, life insurance companies and insurers in stock life insurance companies operated on a mutual basis from an agency-theoretic perspective. Further, this thesis aims to explore from an ownership-theoretical perspective, why this conflict of interest exist. A qualitative research has been performed and the empirical data is foremost based on interviews with persons from the life insurance industry and public prints. The study concludes that the stock life insurance company operated on a mutual basis has two principals whose interests are in conflict. History has shown that stockowners? interests have been prioritized on the expense of the insurers.

Är det effektivt? - En studie av ett företag och dess förvaltning av datorbaserade system

This thesis examines how a company can get an effective, high quality, maintenance of their computerized systems. After literary studies concerning the life cycle activity Maintenance we have studied how the maintenance at the department IT Supply of IKEA IT AB in Älmhult is carried out. What steps and measures in the analyzing of results of changes are carried out and if they have predefined processes for changes. Based on the facts we found most important in our literary studies we have created a model and theoretically applied this to the maintenance of a specific system to see what they can work with to further improve the quality and efficiency in their maintenance. The basis for our thesis is literary studies and the collected material has been used as a foundation for the research at the company, which was carried out through interviews. This thesis is based on the question: ?How do the lack of a model for maintenance and the lack of orientation affect the maintenance in a company??.

Lgr11 ?  Vägen till en modern skola? : En undersökning om lärares uppfattningar i samband med införandet av lgr11

The investigation has taken starting point in the Swedish school history by a look back at the last three curricula and its rating system in order to see the differences and similarities between them. Furthermore, the focus was on the implementation of lgr11 and how it has worked out both on the national and local levels, with the help of, among other things Imsens "five faces of the curriculum" and Lipsky theories of grassroots bureaucrats. The aim of the study was to investigate teachers' perceptions of differences in teaching and assessment in grades 7-9, during the changeover from Lpo94 both on lgr11.The questions developed for this purpose was: How do teachers say that their teaching changed in conjunction with curriculum change? Has there been a refocusing about the concept of knowledge in the curriculum shift, and if so, how?How the assessment and grading did change with the curriculum change?Data collection has been made using a quantitative survey with qualitative elements. The survey consisted of 10 questions that everyone faces the transition to lgr11.

Ekologisk hållbarhet i den fysiska planeringen, teori till handling :

I wrote this essay with the aim to explore, understand and get some insights into what it is that effects the possibilities to plan for ecological sustainability and make it happen. There is no clear definition of sustainable development but world top meetings and reports have developed goals and strategies. I will present some of the theory at hand but most of this essay is based on six interviews with planners at local governments from around the country. Several of the local governments are using the goals issued by the state government by putting them into their large scale plans. During the interviews some obstacles were identified, like a lack of resourses, disadvantaging powerstruktures, conflicts with marketeconomy and simply different meenings about what ecological sustainability is in practice. My method of getting information through interviews and documenting them by taking notes had, as all methods, it?s weakneses.

Projektverksamhet med samhällsnyttan i fokus : införandeprocessen av SMS-biljetten vid Upplands Lokaltrafik

In order to analyze the managerial aspects, we have studied the project of a new payment system implemented at the public-transport organization Upplands Lokaltrafik (UL). The project enables mobile payment by text message (SMS). Most theory concerning the management of projects is developed for private companies.

Disclosure Tone in Environmental Reports ?A study of companies in the energy sector

Background and problem discussion: Sustainability reporting has recently risen in importance and a rising number of companies choose to issue voluntary stand-alone sustainability reports. Their non-regulated nature increases the opportunity for management to angle the information in these disclosures to their own advantage. Lately the focus has shifted from examining what kind of information is provided in environmental disclosures, to analyzing how the information is presented.Purpose: The purpose is to examine if managers in the energy sector use optimistic tone when issuing sustainability reports. The aim is to find out if the tone applied in environmental disclosures is in congruence with either the environmental or economic performance or if an excessively positive tone is being used to mislead readers.Limitations: This study is limited to information found in environmental disclosures from private companies in the energy sector, issued in 2012 or 2013. Environmental performance is defined as the amount of CO2e emissions and economic performance refers to annual company revenues.Methodology: The quantification of optimistic tone is conducted using a content analysis, relying on a pre-specified wordlist and a pilot study.
