The efficiency of the newly launched predatory mite Amblydromalus limonicus : biological control of thrips in cucumber

In this study, the efficiency of a newly launched predatory mite, Amblydromalus limonicus, has been examined for its potential to use as a biological control agent in cucumber production. A. limonicus can be used for biological control of two thrips species, Frankliniella occidentalis and Thrips tabaci. Field trials were conducted in greenhouses of two conventional cucumber growers in Scania, the southern part of Sweden. The basic control agent used against thrips was the predatory mite Amblyseius swirskii. In selected areas, additional A.

Hur gör de? : En kvalitativ studie av hur fyra samhällskunskapslärare tolkar och anser sig använda det demokratiska uppdraget och värdegrunden.

AbstractThe purpose of my study was to examine how four social studies teachers in upper secondary school interprets the democratic educational mission and core values, and if they believe that the same values are tools to influence the students' democratic approach and if they think it is possible. It is also the study's minor purpose to make an analysis of my findings and previous research in the area to explain any similarities or differences in the social studies teacher's interpretation and practice of the democratic educational mission and core values. I used qualitative semi-structured interviews as a method in which the interview questions were based on my research questions. The two criteria I had for my sample of respondents was that there would be social studies teacher at a upper secondary school and that I wanted to have two of each sex. Their interpretation and how they think they practice the democratic educational mission and core values are similar.

Förbättring av Egenvärmehus : En fallstudie av ett flerbostadshus, Kv. Fyrtornet

Energy efficiency has become a very topical issue that has been discussed throughout the European Union for preventing negative environmental impacts that have been associated with the consumption of energy. In the residential sector have mainly municipalities set strict requirements for the reduction of energy consumption while the renewable energy has been asked. Different concepts of low-energy buildings have been developed to reduce the cost of operation and maintenance in existing buildings such as in new ones.This thesis has aimed to minimize the energy cost of a large building which has had low energy consumption features originally. Energy reviews has been initiated in order to be able for showing how the house electricity could be carried out even more efficiently.The work was initiated through a literature study to clearly increase the reliability on the energy subject. Different concepts of low-energy buildings have been treated in connection with its specifications, afterward those have been compared with the obtained results.

Genusstrategier i förskolan : En studie av en förskolas arbete med att motverka traditionella könsroller, ur ett intersektionellt perspektiv

The purpose of this study is to examine a preschool's work to counteract traditional gender roles, which strategies are used and how norms about gender roles are produced and treated. The study also examines whether the preschool has an intersectional perspective in it's gender work, which analyzes how they relate to other categories such as ethnicity, race, class, age and sexuality in their work. I have been observing and conducting four interviews with teachers at a preschool with a gender profile. In my analysis I have used Foucault's theories about discourse and power. The results show that the informants had a high awareness of gender and that the main strategies used were: an individual perspective, seeing the individual and not the sex, and a gender-neutral strategy, removing everything that is gendered, for example, in language and environment.

Stadsdelsparken Skälby i Kalmar : historia, nuläge och framtida utveckling

Skälby park is situated approximately 2,5 km northwest of the central parts of Kalmar and is one of fi ve town part parks. Originally Skälby consisted of a village of four farms. In 1965 the municipality in Kalmar bought Skälby and the agriculture ceased to appear. The land was parcelled out into plots and new roads. Only the area surrounding the old buildings remained, turned to a park.

Skillnader mellan Swedish GAAP och US GAAP : väsentlighetsbegreppet och justeringsposter

Background: With an increased global market, where companies seek capital abroad, the demand for a more uniform accounting standard has been raised. This uniform accounting standard is not yet available, differences between accounting standards still exists. Several Swedish companies seek risk capital in the USA and some are part of a concern that is listed on the American stock exchange. This means that the Securities and Exchange Commission requires the companies to do a reconciliation to US GAAP on those items that are considered material. This can be an extensive work for the companies if the knowledge about the differences between Swedish GAAP and US GAAP does not exist.

Metodik för detektering av vägåtgärder via tillståndsdata

The Swedish Transport Administration has, and manages, a database containing information of the status of road condition on all paved and governmental operated Swedish roads. The purpose of the database is to support the Pavement Management System (PMS). The PMS is used to identify sections of roads where there is a need for treatment, how to allocate resources and to get a general picture of the state of the road network condition. All major treatments should be reported which has not always been done.The road condition is measured using a number of indicators on e.g. the roads unevenness.

Kaliumgödsling på torvmark - effekt på tillväxten hos planterade granar (Picea abies)

Peat  lands  are  a  great  potential  resource  for  increased  forest  growth  in  Sweden, there  are  approximately  6.5  million  hectares  of  peat  lands,  whereof  around  70% produce less wood than one m3sk/ha and year and are therefore classed as forest waste  land.  There  are  over  200  000  hectares  of  peat  land  that  is  already  drained and  wooded,  and  that may  be  suitable  for  fertilization.  Forest  production  on  peat soils  usually  requires  drainage  and  fertilization.  Dewatering  requires  ditching  the area, so that the roots can have access to oxygen. Nitrogen is often abundant in the peat but other nutrients; especially potassium is in short supply. The  purpose  of  this  work  was  to examine  the effects  of  potassium  fertilization  on the  growth  of  spruces  that  were  planted  on  drained  peat  land  and  how  different amount of fertilizers affects the growth. Potassium deficiency is strongly growth inhibiting, since potassium is important for substance  transport  in  the  tree.  Potassium  is  also  important  for  the  carbohydrate formation, and because increasing the sugar content of the cells constitutes a lower freezing temperature does potassium availability in the soil play a major role in the winter  resistance  of  many  species.  Potassium  is  not  found  in  any  organic compounds in the tree, but is present in cell and tissue fluids. A fertilization trial was started in 1978 in Siljansfors Experimental Forest. The plots in the experiment were fertilized with different amounts of potassium and one plot was  left  without  fertilization.  All  plots  that  were  fertilized  with  potassium  grew considerably better than the unfertilized plot. The difference in production between the unfertilized plot and the plot that received the most potassium was 7.2 m3sk/ha and year. The unfertilized plot can still be classified as waste land. The theoretical production capacity was estimated using a Swedish system for site quality  estimation  of  wetlands  after  ditching  (dikningsbonitering).  The  plot  with most  potassium  produced  after  fertilizationaproximately  in  level  with  theoretical estimations.  Key  words:  Peat  land,  Fertilization,  Ditching,  Growth,  site  quality..

Har Expressen fått pippi? : En kritisk diskurs analys av Expressens rapportering kring fa?gelinfluensa

AbstractTITLE Birdflu in the press ? a critical discourse analysis on the tabloidnewspaper ExpressenAUTHOR Per VågebrantSUPERVISOR Malin SveningssonPURPOSE The purpose of this essay is to find out how the Swedish tabloid newspaper Expressen writes about the birdflu H5N1. To be more precise the purpose is to find out how the discourse is constructed. The Birdflu or H5N1 witch is its real name is something that could affect us all, yet very few people know a lot about it. To achieve this purpose I constructed one primary research question:o How has Expressen, in the public media discourse, treated the phenomena we know as the birdflu?This primary research question holds three more specified research questions:o What does Expressens discourse about the birdflu look like?o What actors are participating in the articles?o Why does the discourse look like this?THEORY The theory chapter of the essay contains four different parts.

Värmeslag hos hund : Förebyggande åtgärder, djurägarråd och omvårdnad

The objective of the essay was to identify the nursing care required by a dog suffering from heat stroke and how to educate and advice the owners how to start treating their dog and prevent the condition from occurring in the first place. The essay is based on a literature study. Several databases were searched for scientific research to try find answers to the issues. Keywords concerning the subject were used and mixed in different combinations to sort out the suitable studies. The results of the study indicate that the dog should be cooled by the owner directly after detection. The most crucial issue is to reduce the body temperature as quickly as possible or the morbidity will worsen.

Fenylbutazon - tillåta vid tävling?

Phenylbutazone has been discussed in the world of the equestrian sport several times and different countries have diverse opinions on its use in competitions. The progressive list that permits phenylbutazone with plasma levels up to 8 µg/ml was presented at the FEI General Assembly in November 2009. The list was voted to be accepted, but later several countries realized the consequences and after protests the list was rejected and is going to be discussed again at the FEI General Assembly 2010. In this literature study I have studied the relationship between the concentrations of phenylbutazone in plasma and the effects on lameness. The purpose was to establish whether the limit of 8 µg/ml phenylbutazone in plasma affects the equestrian sport.
