Anlockning och gnag av snytbaggar (Hylobius sp.) : effekt av plantstorlek och behandling med metyljasmonat
Two field experiments were conducted in central Sweden in order to: 1) Determine a relationship between the number of approaching pine weevils (Hylobius sp.) and the number of attacks by pine weevils, in relation to the size of seedlings of Scots pine (Pinus sylvestris). 2) Determine if application of methyljasmonate (MJ) on seedlings of Scots pine will result in higher resistance towards attacks by pine weevils and/or have any effect on the number of approaching pine weevils. The field experiments were designed with two separate parts in close vicinity on the same clear cuttings: a) pitfall traps placed in patches of scarified soil that caught approaching pine weevils at 2.5 cm from the bait, which consisted of different sized seedlings of Scots pine some of which were subjected to application of MJ and b) the same type of seedlings planted out in patches of scarified soil.
The first field experiment was conducted on a 1-year old clear cutting outside Uppsala in east central Sweden and the trapping part of the experiment consisted of 8 blocks with 6 treatments: 1) control, 2) small over-wintered seedling, 3) medium sized seedling, 4) medium sized seedling treated with 0.5 ml 100 mmol MJ 4 days prior to start of experiment, 5) large seedling, 6) vial with 9.5 ml of ?-pinene. The trapping experiment lasted for 6 weeks in the early summer.
Agila metoder ? en kartläggning av teori och praktik
In recent years, agile software development methods have become increasingly popular throughout the world. Today there are a number of different agile methods and they all rest on the Agile Manifesto that was formulated in 2001 as a reaction to the traditional software processes.The aim of this thesis is to make a survey of some of the agile methods used today and to see how they are being used in practice. It consists of two parts: a literature study and an interview study with people working in the software business. First, a definition of agile methods is proposed and a number of different agile methods are described. Second, the interviews are being analysed with special focus on communication, collaboration, expectations and results.
Förgiftningar hos hund och katt
Cats and dogs are often unattended by their owners both indoors and outdoors, and therefore there is always a risk that they will get hurt. In the past, poisoning cases was considered unusual, but nowadays they are considered more common. As a veterinary nurse, it is important to know the common symptoms of poisoning, especially when working with emergency veterinary care. A very essential part of the profession as a veterinary nurse is to inform pet owners about the potentially dangerous substances and how poisonings can be prevented.
The purpose of this report was to find out what is written scientifically about some common poisonings in dogs and cats and to present available statistics that covers the number of animals poisoned by various substances in Sweden. Hopefully this essay can also be used as a handbook for professionals in animal health care and to assist in educating pet owners.
The report mainly covers groceries found in many homes, often easy accessible.
Räfstens vår : Skillnader och likheter i rannsakning och bestraffning ur ett genusperspektiv under ärkebiskop Angermannus visitationsresa våren 1596
The aim of this study was to investigate and analyze similarities and differences in trials and punishment from a gender perspective, during the inquisition in the episcopate of Linköping. A inquisition initiated by duke Karl but performed by archbishop Abraham Angermannus in the year 1596.During the working process a quantitive method was used in the purpose of getting statistic data considering number of men and women that were trialed and punished. A hermeneutic qualitive method was also used in the purpose of closer investigating certain cases that men and women were involved in. The theoretical concepts that have been of importance and used in this study are the individual and the female subject that is based on gender in judicial procedures.The results showed that 49 % of the men were trialed for quarrel. Not as many men were trialed for contempt towards the church and witchery.The most frequently used corporal punishment in this cases were flogging that were executed for totally 38 % of the men.The investigation also proved that men were punished with these forms of corporal punishments for showing their contempt towards the church.

New Public Management i praktiken: En fallstudie i en av Stockholms stadsdelar
In the present thesis, we have studied the management control system in Enskede-Årsta-Vantör, one of Stockholm?s municipal districts, with focus on theories about New Public Management (NPM). When NPM was introduced, a number of complications arose. Some of these, along with the district?s solutions of the complications, are described and analyzed using e.g.
Tidiga membranförändringar i hingstsperma som används för artificiell insemination :
The Annexin-V/propidium iodide (AV/PI) assay detects early membrane changes in spermatozoa and viability using flow cytometry. It is an objective method that evaluates a much larger number of single spermatozoa compared with the usual estimation of motility, the most commonly used method for routine sperm evaluation. In the present study four ejaculates from four stallions were used in a split-sample design to investigate whether and how the number of intact spermatozoa is affected over time and after incubation at different temperatures, either those recorded during shipment of stallion semen for AI (9 or 5°C) or room temperature (20°C). The Annexin-V results did not reflect the motility results that were monitored in parallel. While motility decreased over time, the number of spermatozoa with intact membranes (viable) remained unchanged for at least 21 hours following a short period of initial instability.
Rabies awareness, incidence and vaccination coverage in Lilongwe, Malawi
Rabies kills about 55 000 people every year and more than 90% of infected humans are considered getting the disease from dog-bites. To control the disease and eventually eliminate human rabies, the most efficient and economic method is to keep the dog population vaccinated. The objective of this thesis was to evaluate the situation of canine rabies in two urban areas in Lilongwe, Malawi, where canine rabies is enzootic. In each area 200 household-interviews were conducted in September and October 2013. Focal points were awareness of the disease, human incidence as well as vaccination coverage in the dog population.
Världssamfundets förändrade roll och dess effekter : En kartläggning av humanitära syften inom FN:s fredsbevarande operationer
The aim of this paper is to map out the purposes of the United Nations Peacekeeping Operations. This is done in order to see if humanitarian tendencies have been an increasingly cause for the UN to initiate an intervention with military means. This paper uses the time period from the end of the cold war until today, since that historic occurrence increased the U.N.?s involvement in peacekeeping. By using this time span it enables the survey to indicate changes in the mapping of humanitarian interventions.
Virtuella Communities: Sociala faktorer i digitala miljöer
Virtual Communities is an increasingly common phenomenon on the Internet. Most
of the Virtual Communities are operated and maintained on a non-profit basis
with a direction towards entertainment. However, as more state administrated
and commercial services become web-based, we believe that the number of Virtual
Communities with a community-based or commercial direction will increase in a
near future.
In this thesis, we describe our participation in, and studies of, a
number of Virtual Communities with focus on the IRC-channel ?3dfxsweden?. On
the basis of our experiences, we describe the social elements that form the
foundation on which the Virtual Community rely on.
Hur ser min bok ut? En kvalitativ studie om sex läsares upplevelser av skönlitteratur i olika medieformer
The purpose of this thesis is to examine how reading different media forms can lead to different experiences for the reader and how they choose which media form to read. Two questions are posed in the study. Question number one is: How does the media form influence the reading experience of the book and question number two is: What reasons can be seen behind the different choices of media forms?The study is based upon qualitative interviews with six readers using different media forms. Two different theories are used for analyzing the result.
Kostnadsuppföljning avproduktionskalkyler
Calculations are an important part of planning around a construction project. From concept to completion of the project calculation is a tool to try to predict the actual cost. During the production stage in particular, deviations occur which makes the actual cost different from the calculations.This thesis is done in collaboration with JM Residential Stockholm. The study includes a cost follow-up in which a comparison was made between the calculated production cost and actual cost for the five projects. The aim of the study was to observe the most common reasons that a project deviates from the calculated production cost and then summing these causes in a number of categories.
Har ungdomsarbetslösheten påverkats av regeringens sänkning av arbetsgivaravgiften?
Sweden has for years been struggling with high youth unemployment. The problem is also a hot topic of discussion among experts and politicians, often leading to different proposals to solve the problem. The government chose in 2006 to do something about youth unemployment by lowering payroll taxes for employees up to 25 years. But many experts and studies show that the effects failed to materialize.This study will try to find out if the government subsidies have given any effect on the youth unenployment either by new jobs created or by movement in the labor force. I will use a regression model with an dependent, "difference in difference" variable where the change in the number of employed young people are compared to the change in the number of employed in the subsequent age group.The results show that subsidies are not given any positive effect on the youth employment rate in relation to the subsequent age group..
Mätningar och analys av elnätet hos FHP, Basproduktion
This report is a degree project performed at Freudenberg Household Products AB, (FHP). The degree project comprises measurement and analysis of the power net at FHP Basproduction. The content is divided between one theory-part, one document- part with measurements and also conclusions and a list of measures to be taken. During the project the purpose and restriction change from a quality investigation to only concentrate on harmonics and finding the reason why they exist, and also to find a solution to the problem with harmonics. The measurements shows that the power net contains harmonics of different order and intensity.
