Delia flies (Diptera: Anthomyiidae) are economically important pests in several horticultural crops. The control is commonly relying on chemical insecticides, though there are possibilities with biological control from the natural enemies in the field. An important natural enemy is the parasitic wasp, Trybliographa rapae Westwood (Hymenoptera: Figitidae) that lays eggs in the Delia fly larvae. The parasitoid larva and the host larva have a parallel development until the host dies within its puparium and an adult parasitoid emerges. The aim of this thesis was to understand the attraction to host- and food-associated plant volatiles of T. rapae, in order to enhance the effectiveness of the parasitic wasp as a biological control agent.

Barren rearing environment and early weaning of piglets can lead to a high level of distress, behavioural disturbances and reduction in weight gain. The main aim of this thesis was to study the effects of potential enrichment objects on piglet?s behaviour and weight gain during the pre- and post-weaning period. The second aim was to examine what type of object stimulated the highest frequency of interaction. The study was carried out at the Swedish Livestock Research Centre in Lövsta where a batch of litters from 10 first-parity Yorkshire sows were used.

Detta examensarbete har genomförts i samarbete med Grontmij AB och är ämnat att ta fram tre olika förslag på byggnader med samma utformning men uppförda med olika material i klimatskal och stomme, för att jämföra dess energiförbrukning och slutligen analysera koldioxidutsläppen som genereras. Målet med denna studie är att påvisa vilka material som lämpar sig främst vid hållbart byggande, vilka materialval som främst kan föredras när man vill uppnå energieffektiva byggnader samt analysera dess koldioxidutsläpp.Målet är att påvisa att koldioxidutsläppen minskar med enligt de upprättade miljökraven från Stockholms Stad i samarbete med Clinton Climate Initiative.Climate Positive Development Program lanserades år 2009 och är ett gemensamt initiativ mellan Clinton Climate Initiative och US Green Building Council. Programmet stödjer 18 projekt världen över och Norra Djurgårdsstaden är ett av projekten som ska vara en förebild för framgångsrik ekonomisk och miljömässig stadsutveckling. Programmet är även en vägledning vid byggande av bostäder vilket är avgörande för evolutionen av stadsbygget.Utvecklingen kring byggande har med tiden förändrats och anpassats till mer miljövänliga och energieffektiva alternativ. Idag har det blivit mer vanligt att tala om energieffektiva byggnader och minskade koldioxidutsläpp, vilka är betydelsefulla faktorer som påverkar miljön och vår framtid avsevärt.

Title:Social media as a tool for organizational learningAuthor:David Chaaya & Filip FischerSupervisor:Stig Sörling & Tomas KällqvistBackground:People have always used different ways of communicating. Communication hasa vital role in organizations for control when management and employees are communicatingand interacting with each other to spread individual learning. Thru this contact, individuallearning can develop into organizational learning, which will benefit the whole organization.The most modern tool of communication is social media such as Facebook, Twitter andYoutube. The potential of these social media is disputed in society, but more and moreorganizations are using these kinds of media for communication.Aim:The purpose of this study is to illustrate how social media is used to control withinorganizations and also to create understanding how significant social media are fororganizational learning.Method:The method of this study originates from the ?aktörssynsätt? and is influenced byhermeneutics.

The purpose of this report is to make an evaluation of the self-monitoring for scarification which Stora Enso is using and this study deals with the effects and importance of scarification. A comparison is made in this study with the purpose to highlight any differences between some of the leading forestry companies and significant forest organizations in Sweden. The companies represented in this report are Korsnäs, Mellanskog, SCA, Sveaskog and Södra. In the beginning of this study an interview form was set up together with Daniel Forsberg at Stora Enso. Stora Enso is the head object of this report and seven interviews were made within that company. At the other companies only three interviews were made within each one, with an exception to Mellanskog who wished four.

This paper examines interpellations made in the swedish Riksdag and how they are rhetorically structured to effect and hold government officials accountable in climate policy.?The analysis methodology applied is rhetorical analysis, which aims to identify rhetorical argumentative strategies in the opposition's interpellations between three different periods, 2015-2018, 2019-2022 and 2022-2025. These strategies are ethos, pathos and logos, they are used as glasses in which a rhetorical analysis is conducted on the material. The study reveals that the rhetorical strategies differ between the time periods and that the political rhetoric has become more value loaded over time.? .

Multiple factors are involved in control of beef sensory quality so great variation can be induced. The perception of meat quality can be affected anywhere in the product chain. Both the environment and the set of genes of the animals have an effect on the final output. A problem facing the beef industry today is the significant variations in meat quality between individual animals, which is reflected in the uneven quality of the meat that reaches the consumer. If the quality of meat in stores varies significantly over time, the consumers? trust may decrease.

The aim of this investigation was to assess if there was a correlation between touch avoidance and hierarchical position, perceived degradation, number of years spent in jail and age amongst men at a correctional institution. In addition, a possible correlation between hierarchical position and the amount of perceived degrading treatment was also explored. In the collection of the data a questionnaire containing 27 open and closed answer alternatives was utilized. A multiple regressional analysis was conducted to find possible correlations between touch avoidance and the other underlying variables. Also an independent t-test explored the possible effects of the control variables: place of birth and girlfriend.

In the Swedish governing document for the mandatory school (Lpo94) it is laid down that The school shall strive for being a living social community that gives safety and the will and desire to learn. The social community and the social relations in the school everyday existence are thereby without hesitation very important for the students' learning. The teacher always wants to engage the students and create order, comfort and a good work environment. In this essay, the relationship between students' work climates, matter interests and average grades is studied. This gives understanding and awareness in these important parts of the schools´ daily activity.

The codling moth, Cydia pomonella is a common pest in apple orchards and can be found worldwide. Feeding by codling moth larvae can cause a substantial decrease in apple yield. Control methods comprise for example the use of pesticides, viruses and pheromones. As a sustainable control method, pheromones have been successfully applied to disrupt moth mating behaviour. Other behaviours like foraging, search for mating sites or host finding could be potential targets for additional odour-mediated behavioural manipulation but need further investigations of the underlying odour stimuli and behavioural plasticity. Many insects are attracted to the smell of fermenting fruit and associated microorganisms.

The aim of this Masters thesis is to examine the user service discourses in the field of public libraries that can be identified in four Swedish library journals. Also which underlying causes that control the discourses and the consequences of them are examined. Questions in this study are: which discourses can be found, what characterises them, what kind of different discourses concerning technology in society control the user service discourses and what are the consequences of them. The theoretical starting-point is Ernesto Laclaus and Chantal Mouffes discourse theory. The method is text analytic.

The aim of this study was to evaluate the effects on a simulated wastewater plant regarding GHG emissions and use of energy and resources when implementing source separated wastewater systems. The effects were studied for different restrictions of effluent quality and for different temperatures on the influent. The simulation model BSM2G calibrated for Käppala wastewater treatment plant was used. The task was executed by simulating nine different scenarios with an increase in influent load from new connections equivalent to 3, 10 and 30 % of the present connections. These new connections were served by conventional, urine separated or black water separated systems.

Abstract The goal of the study was to conduct an in-depth investigation of how conflicts are resolved in schools, from a pupil- and a teacher perspective. Our intention was to view and compare pupils and teachers different opinions in the school environment. A major focus was put on different ways teacher handle conflicts and how they try to prevent them. The material was acquired by interviews with both teachers and pupils. The study is based on Jean Piagets and Lev Vygotskijs visions about the cognitive developmental stage for children. The result of the study shows the teachers need to be attentive and also that the pupils generally do not notice when the teacher works to prevent conflicts.
