Side effects of biological control agents in agriculture : does the bacteria Bacillus amyloliquefaciens affect the earthworm Aporrectodea longa?

Pathogenic microorganisms pose a big threat towards food production. Meanwhile, negative impacts on humans and environment are seen by the use of pesticides. Biological control agents are an alternative to the use of chemical pesticides, and plant-growth promoting rhizobacteria, such as Bacillus amyloliquefaciens has been shown to have good properties as biocontrol agents. Before these bacteria can be used commercially their impact on other soil organisms has to be evaluated. This thesis looks into what biocontrol bacteria are and how they might affect earthworms.

Fisk, fågel eller mittemellan? : En studie av tre multiprojektmiljöer

Background: A great part of all projects within Swedish industry are conducted in a multiprojectenvironment, which means that several projects are performed simultaneously. The research within the field of project management is though focused on single projects. Projects are highly dependent on the context in which they are conducted, although the organization of the multiprojectenvironment is only partly explored. Furthermore is the research within the project management highly concentrated on standardization of the project work. The question is whether this implies to the basic advantages with the project-oriented organization, which is flexibility and creativity? Purpose: To describe and obtain an understanding for the multiprojectenvironment regarding management control and organization.

Undersökning av optimeringsalternativ för elektrostatlackering

This report describes a thesis done at the Jönköping University of Technology. The aim of this thesis was to create conditions to optimize an existing automatic electrostatic coating system by changing the technology for dispensing lacquer. To select the technology, a study of different dispensing techniques carried out which concluded that the piezoelectric membrane and electrostatic atomization are the most interesting techniques.In order to perform tests with dispensing techniques a demonstrator has been optimized. The controller and PC software of the demonstrator has been programmed to be able to send out PWM signals that control the dispensers. An adapter card was designed to control the piezoelectric membrane and a steering link to the electrostatic atomization has been developed for PWM signals up to 500V.The work has laid ground for a demonstrator where further testing of the dispensing technologies can be performed..

Undersökning av artikulation, nasalitet och förståelighet hos 16- och 19-åringar födda med isolerad gomspalt

This study highlights the differences in articulation, nasality and intelligibility between twenty 16-year-olds and thirteen 19-year-olds born with isolated cleft palate and control groups. The test groups are compared in a longitudinal perspective and based on earlier evaluations of velopharyngeal impairment. Significant differences were found between test groups and control groups using quantitative comparisons based on SVenskt Artikulations- och Nasalitets-TEst and NasometerTM. The longitudinal comparison also showed a positive but not significant development of the speech. Differences emerged in the comparisons based on velopharyngeal impairment but no significance analysis was made.

An enriched arena for lamb - anticipation behaviour before entering the arena, effects of skipping the anticipation phase and effects of being denied access to the arena

This study aimed to investigate whether lambs show anticipatory behaviours in a holding pen prior to entering a known arena, whether the holding pen experience prior to the arena exposure affects their play expression in the arena and whether their behaviour (in home pen) is affected if arena access is denied. Twenty pair-housed male lambs (average 14 weeks old), were exposed, in chronological order, to five treatments. Holding pen treat-ment (HP-control): Each pair was led into a holding pen (2.7 m2) and remained there for 5 minutes before returning to their home pen (6 m2). Holding pen ? arena treatment (HP-A): Each pair was led into a holding pen for 5 min and then was allowed access into the arena (22 m2, containing two hanging chains, one ball and one platform) for 15 min before re-turning to their home pen.

Y-OQ 2.0 SR : En studie om behandlingens villkor och att tillämpa mätinstrument i behandling av ungdomar

The Youth Outcome Questionnaire 2.0 Self Report (Y-OQ 2.0 SR) has been implemented in residential treatment centre in the Municipality of Örebro as a result of the strive for a more evidence-based working approach within social work. This study aims to examine how personnel and adolescents describe the treatment/counseling and support and the application of the Y-OQ 2.0 SR in the units. The questions cover the values the personnel and adolescents ascribe to the application of the Y-OQ 2.0 SR, if the result from Y-OQ 2.0 SR is congruent with how the adolescents have been affected during the placement, which obstacles and/or possibilities emerge in the management of the instrument and if there are any indications that the Y-OQ 2.0 SR is advantageous or disadvantageous in the treatment process. The study has a qualitative approach; four interviews were carried out with adolescents and five with personnel. The result shows that structure is an important component in attaining a change in behaviour.

Adaptive Charging System : Anpassningsbart laddningssystem för elbilar

This is a master thesis from Uppsala University in collaboration with B Locket AB (more known as www.blocket.se). B Locket AB is a large ad-company from Sweden, located in Stockholm.Search engines on the market today are becoming more and more complex. When they were first introduced, they only had one function and that was to produce search results containing the string that the user had typed. Today, users want it to be able to spellcheck, produce more results and sort search results on specific fields as well. Preferably, all these features should not affect the performance as a whole.The reason to why these demands have come up is that users are getting more and more used to internet services as a whole and they want everything to be as easy as possible.The user ability has become a substantially more important area in the computer industry and this needs to be taken into account when it comes to B Locket AB and its search engine.

Att behålla eller frige sin träl : En studie om frigivning av trälar i medeltida diplom mellan åren 1250-1335

Around the 1950s an explosive population growth started in the Third World. Parallel with the population growth a global network grew up advocating population control and limited population growth. Sweden had a unique place in that network through a pioneering role promoting the issue in the UN organization. During the 20th century Sweden was a pioneer country in terms of initiatives for population control. Ceylon family planing pilot project was something new in a time when other donors considered family planning be too controversial area for bilateral aid projects.

??då hör inte jag hemma hos er!? : - Att ta avstånd från en religiös gemenskap

This study focuses on why people not longer want to be a part of a religious communion they have earlier been a part of. To examine this I have made seven interviews with people who have left their previous communions. Together with the methodological and theoretical discussions on discourse analysis, Richard Jenkins discussions on identity and theories concerning the post-modern society, I have made an analysis on how these people consider their previous communions and its members. They refer i.e. to the social control, the ?closed? culture and the non-questioning-culture that constitute the communions and its techniques.

Byggfel på plåttak : - Bristande kommunikation eller bara slarv?

The mistakes and failures on the roof are noticed during inspection of the construction, many of the commentaries are recurring. A contractor should only need to get a commentary once and then learn from the mistake. It has in this study been brought to light that the solution is not to tell the contractors to "stop slattern", it is more complicated than that. Today, the biggest problems are found in leadership, communication, feedback of experience and that the entrepreneurs take too little responsibility.To minimize the amount of commentaries all contractors need to work with a clearer leadership where the leader is both respected and appreciated. The leader must in an effective way be able to convey all the information to all employees.

Medarbetarsamtalet som ledarskapsutveckling: en kvalitativ intervjustudie och reflektion kring förutsättningen att utvecklas genom medarbetarsamtal

Traditionellt är medarbetarsamtalet till sin form ett organiserat och planerat samtal mellan chef och medarbetare, oftast i syfte att kartlägga behov, krav, verksamhetsmål och förståelse hos medarbetaren. Sedan 1980-talet har det forskats mycket om medarbetarsamtal i Sverige, oftast med utgångspunkt i medarbetarens upplevelse. Vi menar därmed att det saknas ett perspektiv, nämligen det på chefen och dennes utveckling av sitt ledarskap. Vi har därför valt att analysera medarbetarsamtalet som en förutsättning för ledarskapsutveckling. Eftersom det inte finns mycket forskning om denna omvända syn på medarbetarsamtalet, har vi valt att med ett explorativt förhållningssätt genomföra en kvalitativ intervjustudie med fem chefer som i sitt arbete utför medarbetarsamtal.
