This pilot study examined whether treatment with Vortex Process Technology (VPT) of the irrigation water used on tomato (Solanum lycopersicum) plants had any effect on plant growth. In a block experiment, with two blocks comprising 12 vases containing 1 L water and two tomato plantlets, treatment in which, nutrient solution was based on Vortex-treated water was compared with an control using untreated water. All vases were kept in a static aerated culture system in a daylight chamber for four weeks. The results showed that the effect of the two blocks exceeded the effect of vortex treatment in terms of leaf area and weight of fresh and dry matter. Plant height, stem width and internodal length were significantly different in tomato plants grown in Vortex-processed water compared with the untreated control.

De virvelgator som bildas i atmosfären bakom höga berg på öar påminner till utseendet starkt om de periodiska flöden som uppstår vid strömning kring en cirkulär cylinder. Friktionen mellan fluiden och cylinderns yta gör att det bildas en vak nedströms cylindern. Periodisk virvelspridning där von Kármán-virvlar sänds ut kan uppstå. Utifrån Reynolds tal går det att karaktärisera strömningen och med hjälp av en numerisk modell kan tillstånden simuleras. Saknas en turbulensmodell i algoritmen blir resultaten för höga Reynolds tal felaktiga. De atmosfäriska virvelgatorna uppstår dock inte på grund av friktion.

This report is a Master?s Thesis performed by Andreas Adolfsson and David Jacobsson atChalmers University of Technology. The purpose of this master?s thesis is to evaluate anew method for load-shedding, the voltage controlled underfrequency load-sheddingdeveloped by ABB. This report presents a comparison between conventionalunderfrequency load-shedding and this new method for load-shedding.

The problem presented in this report is that of finding a method to calculate the lift force from a single-element airfoil of arbitrary shape. A number of restrictions are used in order to simplify calculations while retaining reasonable accuracy. The problem is solved for the two-dimensional case only and no finite-wing effects are taken into account. Furthermore, inviscid and incompressible flow is assumed. The method used to solve the problem is the vortex panel method, with vortex singularities distributed over simplified airfoil geometry.

Syndecan-1 is a cell surface proteoglycan which participates in cell adhesion, differentiation, motility, morphogenesis and intracellular signaling. The two glycosaminoglycans heparan sulfate and chondroitin sulfate are covalently attached to the ectodomain of syndecan-1 via a tetra saccharide linkage sequence. However, the ectodomain can be modified having only one or neither of the glycosaminglycans attached. The glycosaminoglycans are capable of binding ligands such as fibroblast growth factors (FGFs) and support activation of receptors. The ectodomain is proteolytically cleaved from the cell surface by metalloproteinases in a process known as shedding.

Blood samples from 44 clinically healthy cats were analysed for the presence of antibodies to Chlamydophila felis. As we wanted to investigate if the antibody titre of clinically healthy cats correlates to shedding of chlamydia, conjunctival and vaginal or preputial swabs respectively, were taken and analysed with rtPCR (real-time polymerase chain reaction) for the presence of chlamydia DNA. Furthermore, to investigate possible epidemiological factors connected with asymptomatic cats infected with chlamydia and to see if there were any indications that chlamydiosis can cause reproductive problems, the owners of the cats were asked questions regarding this. Sixty-one per cent (27 of 44) of the cats were seropositive. Three of these (11 %) had the highest antibody titre (1:1600).

This paper aims at shedding light on the effects of a broken psychological contract in terms of job satisfaction. In a qualitative field study, the author researches seven newly recruites employees about their expectations when starting their jobs at the rapidly growing, Swedish company Klarna. Using Herzbergs two-factor model of hygiene and motivation factors as well as modern motivation theory, i.e. self-determination theory, the study answers questions as to what makes a candidate choose a company and what factors motivates as well as demotivates the recruit at the job, in the onboarding phase. The result is an attempt to describe what makes a recruitment process successful..

This paper analyses the character judge Holden in Cormac McCarthys novel Blood Meridian through an ethical perspective. The author uses several methods to analyze the character ethically, such as the western-genre, McCarthys authorship, evil as an ethical term and Friedrich Nietzsche's theory the Übermensch. The author then uses a selective group of scenes and chapters from the novel to highlighting the distinctive ethical characteristic of judge Holden. The author finds judge Holden to be the very principle of violence and blood shedding, defending and distributing these principles in his words and his actions throughout the novel. Triumphantly proclaiming his victory, judge Holden embodies the principle that whoever has the power to perform any action has then the moral right to do so.

Havsmiljöer är idag den slutliga anhalten för den nedskräpning av plast som kommer ifrån avloppsvatten och allmän nedskräpning. Stora mängder plastpartiklar i olika storlekar har upptäckts i haven och även inuti djur som misstagit plasten som föda. Forskning visar att en stor del av plasten är av mikroskopisk storlek, så kallade mikroplaster. Inom denna grupp förekommer textilfibrer som likt andra plaster är svårnedbrytbara i naturen. Det har genom studier påvisats att små textila fiber rinner ut med avloppsvattnet och hamnar i haven.PET är en av de vanligaste plasterna och utifrån denna tillverkas polyesterfiber som är det i särklass mest använda materialet inom textiltillverkning.

A research review shedding light over organizational cultureand its affect on knowledge sharing. The purpose of thereview was to give an overview of the current researchmeanwhile answering the research questions how and whyorganizational culture influences knowledge sharing.Through careful selection of articles, from Journal ofKnowledge Management, a review of the material led toareas of emphasis being identified: motivation, trust,organizational structure, management, communication andrewards. For each area of emphasis the results from thechosen articles were presented and analyzed, leading toconclusions that the how and why of organizational culture?sinfluence is due to mainly individual motivational factorsamongst staff. This implies that organizations need to keepfocus on the psychological factors affected by organizationalculture when looking to make knowledge sharing moreefficient.

This assignment is a venture into the use of the concept alchemy in the texts on analytical psychology written by Carl G. Jung. Originally the idea was to compare the blending of colours in art painting with the Jungian understanding of alchemy. In order to understand the many and it seems differentiated correlations to alchemy in the texts on analytical psychology written by C.G. Jung, I have found it necessary to investigate the history of alchemy in modern Europe and the Egyptian figure of Hermes Trismegistos.

This comparative study explores Swedish and Danish teachers? perspectives on students with intellectual disabilities and their education. The research focuses on the 1960s, a pivotal decade marked by paradigm shifts from medical to socio-constructivist views on intellectual disabilities. Through qualitative text analysis of articles from the Nordic Journal of Special Education (Nordisk tidskrift f?r specialpedagogik), this study examines how teachers described these students, the prevailing norms versus perceived deviations, and their proposed teaching strategies.

This Master's thesis examines segregation between Swedes and immigrants in school, and more specifically segregation between the two elementary schools Vikingaskolan and Tunaskolan in Lund. This case provides a particularly interesting puzzle, since Lund doesn?t have any pronounced immigrant districts, and was also recognized nationally as best municipality for its schools (2004). In this thesis we try to understand the segregation between the two schools in Lund as an implementation dilemma.The theoretical framework applies a model designed by Lennart Lundquist, which includes three potential causes for implementation problems: the implementer doesn?t understand the decision, the implementer can?t apply the decision, the implementer doesn?t want to carry out the decision.

The purpose of this paper is to understand the climate of the street and how it can be modified to better meet the needs of the street and the user groups. At the same time the conditions of the street and its surroundings also has to be taken into account. To accomplish this it is necessary to have a broad knowledge of the climate conditions in the city. Therefore an overview of the climate elements and how these are modified in the built-up areas are given. The part of the paper which deals with the city climate has a global approach to be able to give an as complete picture as possible.

The object of this explorative theoretical study is to compare similarities in three perspectives for evaluation of credibility. The perspectives are the historical method source-criticism, cognitive authority and domain analysis. These perspectives, regarded as intellectual tools for critical thinking in a process of information seeking, by asking questions about credibility related to the social and theoretical context of the intellectual background, can give support in articulating which documents that gives a specific and essential answer to a question. In this sense credibility is seen as a qualitative aspect of relevance. Patrick Wilson argues that we can attain some critical independence towards cognitive authorities and the literature by investigating the social and theoretical topography of a field.
