Filimon Fasola, Magdalena (2006) Könssegregerat eller könsintegrerat grupparbete? (Gender segregated or gender integrated workgroups?) Malmö: Lärarutbildnnigen
Syftet med examensarbetet var att undersöka vilken inställning till arbetet i könsintegrerade respektive könssegregerade grupper eleverna har i de klasser jag undervisade i under min vft. Undersökningen gjordes i två klasser, en sjua och en åtta. Arbetet avgränsades av tre frågeställningar:
• Vilken inställning har eleverna till arbetet i könsintegrerade respektive könssegregerade grupper?
• Har vanan att umgås med det motsatta könet utanför skolan någon betydelse för hur eleverna ser på arbetet i könsintegrerade respektive könssegregerade grupper?
• Har gruppsammansättningen någon betydelse för hur eleverna arbetar?
Arbetet grundar sig på litteraturstudier och en kvantitativ undersökning som består av en enkät.
Min slutsats är att både pojkarna och flickorna i undersökningen föredrar könsintegrerade grupper.
Nyckelord: Genus, grupparbete, könsintegration, könssegregation

Filimon Fasola, Magdalena (2006) Gender segregated or gender integrated workgroups?
The aim with the essay was to investigate what is the attitude that pupils in the classes I was teacher to during my practice have regarding gender integrated respective gender segregated workgroups. The investigation was made in two classes, a seventh and an eight. The study was limited by three questions:
• What is the attitude that pupils have regarding gender integrated respective gender segregated workgroups?
• Does the habit to spend time with the opposite sex outside the school have any significance for how the pupils perceive gender integrated respective gender segregated workgroups?
• Does the group’s assembly have any significance for how pupils work?
The work is based on studies of literature and a quantitative investigation which consists of a questionnaire.
My conclusion is that both boys and girls who took part in the investigation prefer gender integrated workgroups.
Key words: gender, gender integration, gender segregation, workgroups.

UNSTEADY INVESTIGATION OF THE DLR TIC NOZZLE BY DIFFERENT TURBULENCE MODELS
No full textAfterbodys of launchers and re-entry vehicles are characterized by large base regions submitted to intense back flow, aerodynamic instabilities and pressure fluctuations on the afterbody and on the nozzle region. Consequently in addition to experimental investigations a necessary capability of numerical tools is the capability to simulate unsteady super- and hypersonic flow fields of such configuration and to resolve turbulent wake flows, interacting with nozzle sections, on realistic launcher configurations.
One of the experimental activities in this scope was performed by DLR at the P6.2 facility in Lampoldshausen, Germany, providing an experimental data base for the DLR TIC nozzle under overexpanded cold gas conditions. Key objectives of this test case are the correct prediction of the separation location and the assessment of the resulting unsteady side load torque. The geometry was specified by DLR, including nozzle inner and outer wall and the inflow geometry upstream the nozzle throat.
The present computations were performed as a feasibility study, end preliminary results are presented here.Different computations on unstructured grids were carried out with grid adaptation at the shock structures. The test case was investigated by different descriptions of the turbulent flow field such as one equation URANS models and a DES (Detached Eddy Simulation) type simulation as well as laminar conditions. It has to be pointed out that the investigated grids are too coarse for a realistic DES and the resulting turbulence is only insufficiently resolved. Nevertheless the behaviour of the model under these conditions had to be investigated to earn experience for further simulations
Divide, conquer, entertain: film melodrama and authoritarianism in Europe
No full textThis dissertation examines the role played by the popular film melodrama of interiority in the dissemination and normalization of authoritarian ideology regarding the private and intimate spheres in France under the German Occupation (1940-1944), Spain under Francisco Franco in the 1950s (1951-1961), and Romania under Nicolae Ceauşescu in the late 1960s (1965-1971). Two major theoretical concepts, strongly connected with each other, structure my analysis: the intimate sphere, which I define as the space of discourse created among the closest emotional and psychological groupings of family and friends; and the melodrama of interiority, which I describe as one of the two major tendencies of the melodramatic mode centering on the conflicts within the intimate sphere. This theoretical aspect is doubled by a historical grounding of my dissertation in the social, economic, and political context of each country, with a specific focus on the organization and transformation of the three chosen cinema industries. Each authoritarian state sought to eliminate or control private groups and associations, and to reorganize intimate publics following a conservative, patriarchal model that emulated the relationship between the state and its citizens. Films were produced, distributed, and exhibited with the full knowledge of authorities. My analysis of the most popular melodramas of interiority in each country—L’éternel retour (The Eternal Return, 1943) in France, El último cuplé (The Last Torch Song, 1957) in Spain, and Dacii (The Warriors, 1967) in Romania—suggests that their commercial success relied on the well-organized system of production and promotion that supported them and on their melodramatic characteristics; these films contributed to the ―naturalization of state ideology regarding the intimate sphere. Through such texts, authoritarian regimes sought to seduce and conquer their publics.Ph. D.Includes bibliographical referencesby Monica Elena Filimo
Molecular pathogenesis of Mycoplasma bovis
No full text© 2019 Filimon Mitiku HaileMycoplasma bovis is an important pathogen in cattle production systems worldwide and causes significant economic losses. It causes mastitis, pneumonia, otitis media, keratoconjunctivitis and polyarthritis in affected cattle. Antibiotics have limited efficacy in treating M. bovis infections so vaccines are considered the method most likely to achieve effective control of the disease it causes.
As M. bovis lacks a cell wall, lipoproteins, which are exposed on the cell surface, play a key role in its survival in the host through their role in the acquisition of essential nutrients, in adherence to cell surfaces, in colonisation of the host and in evasion of the immune system. Mycoplasmas are the simplest free-living organisms, and are generally regarded as having evolved to retain only the essential machinery necessary for survival in their hosts. This study sought to understand the functions of selected membrane genes of M. bovis and their roles in adhesion, colonisation and immune evasion.
The gross pathology of respiratory disease caused by M. bovis is characterised by the presence of areas of caseous necrosis and purulent exudates in the affected pulmonary tissues. Calves experimentally infected with M. bovis have an infiltration of neutrophils into the bronchioles. The studies described in this thesis showed that these neutrophilic infiltrates contained neutrophil extracellular traps (NETs) by detecting changes in the morphology of neutrophils in these sites, and free histones and neutrophil elastase, which are derived from the nuclear components of NETs.
Further investigations of the induction of NETs by M. bovis were conducted in vitro using neutrophils isolated from the blood of healthy cattle. These studies demonstrated that M. bovis does induce the formation of NETs by neutrophils, but that the stability of these NETs was compromised by the product of the major membrane nuclease gene mnuA. The MnuA nuclease is the major nuclease of M. bovis detected in vitro. A fluorescence assay was developed to quantify NET formation when neutrophils were stimulated with M. bovis strain PG45 and mutants derived from it. The formation of NETs in bovine neutrophils was dependent on the presence of a relatively high concentration of M. bovis (a multiplicity of infection of 100), but NETs were degraded at very low concentrations of M. bovis, demonstrating the potency of the MnuA gene product in the degradation of NETS and its likely role in enabling M. bovis, and possibly other bacteria at the sites of infection, to escape from NETs. Ovine neutrophils were also shown to release NETs after stimulation with M. bovis and the MnuA nuclease also degraded these NETs. M. bovis-induced NETosis was found to result from stimulation of an alternative pathway to the classical NET induction pathway. It was dependent on neutrophil elastase and the ERK pathway, but was induced independently of the formation of reactive oxygen species (ROS), or the protein kinase C (PKC) and MAPK pathways. These studies suggest that the MnuA nuclease assists M. bovis in evading the innate immune system and in the establishing chronic infection.
Mycoplasmas must adhere to epithelial cell surfaces to successfully colonise their host. To determine the role of selected genes of M. bovis in adhesion, an in vitro adhesion assay was developed using the Madin-Darby bovine kidney (MDBK) cell line. The adhesion of wildtype M. bovis strain PG45 was compared to mutants in which a transposon had been inserted into the open reading frames MBOVPG45_0416 or MBOVPG45_0565. The products of both of these genes have been found to have fibronectin binding activity in earlier studies. Both mutants had significantly reduced binding to MDBKs compared to the wildtype strain. In addition, adhesion of wildtype PG45 to MDBK cells was significantly inhibited by treatment of the M. bovis PG45 wildtype strain with polyclonal sera raised against the products of MBOVPG45_0565 or MBOVPG45_0416. Taken together, these findings are consistent with a significant role of these gene products in the adhesion of M. bovis to cell surfaces.
In conclusion, the studies described in this thesis have demonstrated the likely role of three membrane genes of M. bovis in its survival in the host and have highlighted some of the mechanisms that contribute to the virulence of this pathogen. This in turn has enhanced our understanding of the pathogenesis of the disease caused by this organism and will assist in the design of vaccines and diagnostic tools that can be used to more effectively control disease caused by M. bovi
Sailing the Wind: Evaluating the Impact of COMA on Multi-Agent Active Wake Control in Wind Farms: What is the effect of COMA on the problem of AWC compared to single-agent RL algorithms?
No full textThe close proximity of wind turbines to one another in a wind farm can lead to inefficiency in terms of power production due to wake effects. One technique to mitigate the losses is to veer from their individual optimal direction. As such, the wakes can be steered away from downstream turbines in order to increase the overall power output. Multi-Agent Reinforcement Learning (MARL) models the interactions between wind turbines and determines an optimal control strategy through agents that learn the collective consequences of their actions. Toanalyse the benefit of multi-agent cooperation and centralised critic evaluation, I investigated the effect of Counterfactual Multi-Agent Policy Gradients (COMA) on Active Wake Control. Ultimately, experiments on wind farms of three and sixteen turbines indicate that the algorithm performs moderately, yet worse than single-agent Reinforcement Learning. In addition, high computation costs hinder its application on real-life environments.CSE3000 Research ProjectComputer Science and Engineerin
