Motiv och avkastningsvärde vid köp av skogsfastigheter : en intervjuundersökning

The purpose of this paper has been to find out what motives buyers of forest property has for there purchasse, what competence they have in economics and forestry, and what analysis they had done before the purchase. The study is based on interviews with nine different buyers from two geographical areas, five from Hälsingland and four from Småland/Skåne. A forest property is a property where the value to 100 % consist of forest. A part from the interviews every purhase has been analysed in comparison to an estimation of the yield value. The theoretical yield value was estimated with a computer programme.

Green structure planning in Transit-oriented Development (TOD) : a spatial analysis of Önnestad

During the winter 2011 Isaksson and Andersson did a time budget study on Nordens Ark?s Przewalskis horses during daytime when there were visitors and caretakers in the park. This time budget study was made during daytime and when there were no visitors or caretakers in the park. The horses where observed in the morning (5.30-6.30 am) and in the evening (5.45-6.45 pm) during four days. In addition to a time budget, the horses? positions in the enclosure were registered.

Utvärdering av en subjektiv metod för att skatta mängden trädbiomassa längs vägkanter :

Forest biomass is becoming an increasingly important source of renewable energy, and thereby the demand is increasing. There is currently 213 000 km of forest roads in Sweden that could be suitable for biomass harvesting. Harvest of biomass along forest roads both provides biomass and maintains the quality of the roads. Currently, the volume of biomass along roads can only be assessed post harvest, chipping and industry deliverance. As the decision of whether or not to harvest should preferably be based on more than experience, the TJ-method has been proposed. The TJ-method is a subjective method to quickly determine the dry matter quantity with the assessment being conducted from the roadside.

CFD-simulering av kallras från fönster : Konvektorers och nischdjupets inverkan på lufthastigheter i rummet

During cold winter days it is likely that people in buildings with older windows or high glass facades experience thermal discomfort due to cold air down draughts. Earlier work has been aimed at finding analytical methods to predict the speed of the airflow in a room and in practice heating appliances are often placed beneath the windows to reduce the draught along the floor. In a study from 2012 Mohammad Parchami developed a method for estimating the required heating power to counteract the downdraught with such heating appliances. In this study, Computational Fluid Dynamics (CFD) was used to evaluate the usefulness of Parchami?s method and also to examine the potential of adapting the depth of the inward window sill as a means of decreasing the down draught.

BVC-sjuksköterskors erfarenheter av att arbeta med formulär om 3-5-åriga barns beteende och sociala förmågor

Background: The lack of knowledge regarding preschool children's mental health prompted Uppsala University, in collaboration with Uppsala Kommun, to start a study in which children aged 3, 4, and 5 years are screened using the "Strength and Difficulties Questionnaire" (SDQ). This screening method has been introduced into the majority of Uppsala County child care centers (BVC), and the nurses' experience of working with this method is examined in this paper.Method: A qualitative approach with semi-structured questions was used to interview ten nurses who pioneered the SDQ Method. The interviews where recorded, transcribed and analyzed using content analysis.Results: Three themes and nine categories were identified from the interviews. The themes were: "Attitude and motivation are important when working with the form", "Clearer overall picture with preschool answer", and "A tool to identify difficulties". The results show that the nurses were satisfied with the form.

Jämförelse av olika metoder att generera Bernoullifördelade slumptal givet deras summa

In this master?s thesis the problem of simulating conditional Bernoulli distributed stochastic variables, given the sum, is considered. Three simulation methods are considered, namely the acceptance/rejection technique, Bondesson?s method and the Markov chain Monte Carlo method.To compare the three methods the bias and the standard deviations of the simulated variables are evaluated. The results of the simulation study shows that the Markov chain Monte Carlo method is not the best method for this type of simulation.

Metodik för utmattningsberäkning av svets i vibrationsmiljö

In this work, a method was developed and evaluated for calculating the life of welds under the influence of fatigue loads from a vibration environment. Typically, a shaker table is used for testing a component against vibration loads. The shaker table creates a vibration environment that is defined in the frequency domain by a power spectrum.Similarly, a virtual vibration table can be used to calculate the same type of load environment, which can then be used to calculate the expected lifetime. The benefit of this method is that it can be used in design, as well as in simulation of tests before physical verification tests are carried out.Today there are methods for calculating fatigue life of non-welded base material, but since many components contain welded joints, there is a need to apply this method to those types as well. To achieve this, the thesis combines two different areas, which together provide a method for fatigue assessment of welds using a virtual shaker table.The methodology is carried out by modeling the component, and its welded joints, in a finite element program.

Värdering av prestation och riskbeteende i ung ålder : Finns det ett samband?

This paper is a study how students at a high school in Falun, Sweden, estimates theirperformance in an upcoming math test which is then compared with the actual grade thestudent performed. The students who participated also answered questions related to ?risksituations? to examine whether there is a correlation between how students estimate theirperformance in the context and their risk behavior, and if the students act like economicmodels assume. In agreement with previous studies, the boys in the survey tended to beoverconfident in their performance. The girls in the study were neither over- norunderconfident in her performance and no significant difference in the estimation of one'sperformance between the sexes could be proven.

Deriving ECA-rules from timed-automata specifications.

Real-time systems are required to answer to external stimuli within a specified time-period. For this to be possible, the systems behaviour must be predictable. The use of active databases in real-time systems introduces unpredictability in the system, e.g. due to their use of active rules. The behaviour in active databases is usually specified in ECA-rules.

Vakuumassisterad sårbehandling : en metod för en utveckling av dagens hästomvårdnad

It is common knowledge that our horses do occasionally hurt themselves and cause damage to their bodies. They also manage to do it in the most remarkable ways. The problem is not that they hurt themselves, because everybody does so from time to time. The problem is that they often experience difficulties with the healing of the wounds. The cause to that problem is the fact that they often lose a vast amount of tissue, the wound is more often than not extensively contaminated and the wound is often found a long time after the accident occurred.

Stress test methods : a potential approach to hurry up shelf-life tests on oat products

The aim of this Master?s thesis was to find out more about the delimiting quality- and shelf-life parameters over time for liquid oat-based products. According to that, to present applicable subjective and objective shelf-life test approaches at accelerated conditions. The study aimed to gain a deeper knowledge concerning the general and accepted way of performing accelerated storage tests. This study focused especially on products, which suffer from quality failure caused by oxidation, such as liquid oat-based products.

2013. The brave new time.We constantly look forward in time. There is a need today to constantly renew, replace and update almost everything in our lives. Although often stressful, these continual changes and upgrades can open up new possibilities and even be seen as enjoyable and stimulating.Values, opinions, and everything we create, is based on an experience of the past and predictions of what the future might be. I want to take advantage of these thoughts and find out how they relate to our exchangeable culture.

Utvärdering av BeWi Byggsystem

The construction industries are relatively conservative type of business that takes a longtime to adjust for new methods and embrace new ideas. It dose not matter if the newmethod seems to be an improved method as long as it is new and untried. Constructioncompanies are reluctant to change form a longtime working method to a relativelyunknown method.The purpose with our report is to perform an evaluation of BeWi construction method.Our goal are to present the generally opinion about BeWi from the contractors that hasbeen in contact/worked with the method. We also want to know from the contractor?spoint of view if BeWi and the method measure up to the standards that are presented byBeWi and if they believe that improvements need to be done.Our progress up to the final report has consisted of three parts[1]Field studies[2]Interviews[3]Literary studiesWe started out with field studies where we took notes and observed all the includedworking phases on the construction site when using the BeWi method.

Trender i ämnesval hos magisteruppsatser inom kunskapsorganisation 1995-2005 : en innehållsanalys

The aim of this study is to establish whether there are any specific trends in master theses concerning knowledge organization. To identify the past and current trends a method of content analysis has been applied to 110 theses over a time period of ten years. The results of this study show that there is an increasing interest in subjects concerning for example the evaluation of retrieval effectiveness in search engines on the Internet. A subject which was popular in the late 1990:s was information technology and its different applications. This subject has since that time decreased in popularity.

Evaluation of an automated multiplex real-time RT-PCR assay for rapid detection of Influenza A and B viruses

Influenza is a viral infection that affects global health and economy with its endemic and sometimes pandemic spread. Rapid detection of Influenza viruses enables antiviral use and can bring financial savings. It is also essential for the global surveillance of prevalent Influenza strains. RT-PCR is considered the most specific and sensitive method for detection of Influenza, but Influenza mutates at a high rate and it is therefore crucial that RT-PCR methods are updated regularly.In 2014, Cepheid released their Xpert Flu/RSV XC assay, which can detect Influenza A and B and RSV by multiplex RT-PCR in approximately one hour. The aim of this study was to evaluate this assay at Laboratoriemedicin Västernorrland by using the laboratory?s previous PCR assay for detection of Influenza viruses as reference method.Real-time RT-PCR was used to compare Xpert Flu/RSV XC to the reference method.
