Kan klippningen i en film påverka hur en karaktär framställs och uppfattas av tittaren? Syftet med den här uppsatsen är att analysera och jämföra två utvalda scener från filmen Låt den rätte komma in och de två motsvarande scenerna i remaken Let me in. Detta för att se huruvida klippningen kan påverka hur karaktärerna upplevs och vilka skillnader det finns när det gäller vilken klippteknik som använts i de båda filmerna. Med hjälp av Jens Eders analysmodell Karaktärsklockan som används vid analys av karaktärer och Roger Crittendens teorier om filmklippning, undersöker uppsatsen hur karaktärerna framställs och upplevs genom användandet av olika klipptekniker. Resultatet visar på att det går att fastställa att klippningen har haft stor påverkan hur karaktärerna i Låt den rätte komma in och Let me in uppfattas av tittaren. Det är även väldigt tydligt att klippningen och valet av olika klipptekniker skiljer sig åt mellan de två scenerna och karaktärerna har således framställts på olika sätt.

Participation in post-compulsory computing education has declined over recent years, both in the senior years of secondary school and at university. This trend has been observed in most developed countries, despite reported and projected skills shortages in Information Technology (IT) industries. Within the computing education enrollment mix, girls and women continue to be under-represented and recent years have seen female participation fall even more rapidly than that of males. This article reports on findings of an Australian study which explored secondary school students’ beliefs about and attitudes towards computing education and careers in IT. Factors that might discourage girls in particular from pursuing post-compulsory computing education and careers are discussed, along with broader implications for school education in an era when information and communication technologies are an integral part of our daily lives. Findings include the persistence among both boys and girls of inaccurate and outdated views of the field of IT and low expectations of both school IT curricula and pedagogy in terms of their relevance and interest for students. Many of the issues identified as discouraging students in general from pursuing computing education appear to have a greater discouraging effect on girls, and this is compounded by stereotypical views of the field as male-dominated and unwelcoming to women and girls.

A quantitative phase analysis was made of LiXCoO2 powders obtained by two distinct chemical methodologies at different temperatures (from 400 to 700degreesC). A phase analysis was made using Rietveld refinements based on X-ray diffraction data, considering the LiXCoO2 powders as a multiphase system that simultaneously contained two main phases with distinct, layered and spinel-type structures. The sults showed the coexistence of both structures in LiXCoO2 obtained at low temperature (400 and 500degreesC), although only the layered structure was detected at higher temperatures (600 and 700degreesC, regardless of the chemical powder process employed. The electrochemical performance, evaluated mainly by the cycling reversibility of LiXCoO2 in the form of cathode insertion electrodes, revealed that there is a close correlation between structural features and the electrochemical response, with one of the redox processes (3.3 v/3.9 v) associated only with the presence of the spinel-type structure.

The culture supernatant of Escherichia coli, isolated from ostriches with diarrhea in Brazil, caused elongation in Vero cell, rounding in Chinese hamster ovary (CHO) cells and a cytoplasmic vacuolation in ostrich embryo fibroblasts (OEF), but it was not cytotoxic for chicken embryo fibroblasts (CEF). These effects were not neutralized by antiserum to cholera toxin. Polymerase chain reaction assays showed that the ostrich E.coli contained the gene encoding (eltII-A), but not those for type 1 heat-labile enterotoxin (eltA), heat-stable enterotoxins (estA, estB), verocytotoxins (stx-I, stx-II), or cytotoxic necrotizing factors (cnf 1, cnf 2). All isolates belonged to serotype O15:H8. The enteropathogenic relevance of LT-II in ostrich diarrhea remains undetermined. (C) 2004 Elsevier B.V. All rights reserved.

The aluminum alloy 2524 (Al-Cu-Mg) was developed during the 90s mainly to be employed in aircraft fuselage panels, replacing the standard Al 2024. In the present analysis the fatigue crack growth (FCG) behavior of 2524-T3 was investigated, regarding the influence of three parameters: load ratio, pre strain and crack plane orientation of the material. The pre strain of aluminum alloys is usually performed in order to obtain a more homogeneous precipitates distribution, accompanied by an increase in the yield strength. In this work, it was evaluated the resistance of Al 2524-T3 sheet samples to the fatigue crack growth, having L-T and T-L crack orientations. FCG tests were performed under constant amplitude loading at three distinct positive load ratios. The three material conditions were tested: as received(AR), pre strained longitudinally (SL) and transversally (ST) in relation to rolling direction. In order to describe FCG behavior, two-parameter kinetic equations were compared: a Paris-type potential model and a new exponential equation introduced in a previous work conducted by our research group. It was observed that the exponential model, which takes into account the deviations from linearity presented by da/dN versus AK data, describes more adequately the FCG behavior of Al 224-T3 in relation to load ratio, pre strain effects and crack plane orientation. © 2011 Published by Elsevier Ltd.

Decision making in honeybees is based on in- formation which is acquired and processed in order to make choices between two or more al- ternatives. These choices lead to the expression of optimal behaviour strategies such as floral constancy. Optimal foraging strategies such as floral constancy improve a colony’s chances of survival, however to our knowledge, there has been no research on decision making based on optimal storage strategies. Here we show, using diagnostic radioentomology, that decision mak- ing in storer bees is influenced by nectar sugar concentrations and that, within 48 hours of col- lection, honeybees workers store carbohydrates in groups of cells with similar sugar concentra- tions in a nonrandom way. This behaviour, as evidenced by patchy spatial cell distributions, would help to hasten the ripening process by reducing the distance between cells of similar sugar concentrations. Thus, colonies which ex- hibit optimal storage strategies such as these would have an evolutionary advantage and im- prove colony survival expectations over less efficient colonies and it should be plausible to select colonies that exhibit these preferred traits.
