Bewertung und Optimierung von dynamischen Dämmsystemen unter Berücksichtigung des Wiener Klimas
Authors: Burdajewicz Filip , Korjenic Azra , Bednar Thomas 
Published: February 2011

AbstractIn den letzten Jahren fanden immer wieder Anstrengungen statt um den CO2‐Haushalt der Erdatmosphäre zu senken. Begriffe wie “sparsamer”, “effizienter” oder “effektiver” werden häufig in diesem Zusammenhang verwendet. Auch das Fachgebiet Bauphysik kann einen wesentlichen Beitrag zur Energieeffizienz leisten. Das ist eine berechtigte Forderung, da Gebäudeheizung und Gebäudekühlung einen bedeutenden Anteil am Ausstoß schädlicher Treibhausgase besitzen. Grenzwerte für die U‐Werte werden immer niedriger angesetzt, was dickere und teurere Dämmsysteme zur Folge hat. Neben diesen trivialen Lösungen werden auch komplexere Systeme entwickelt und erprobt. In dieser Untersuchung werden zwei davon genauer betrachtet und bezugnehmend auf den Heiz wärmebedarf sowie den Kühlbedarf gegenüberstellt. Dabei handelt es sich um sogenannte schaltbare Dämmungen, und um ein neues System mit der Bezeichnung “Thermocollect”. Ein Vergleich beider Systeme ist mit Software‐Standardlösungen nicht möglich, da diese mit nichtvariablen Wärmeleitwerten arbeiten, weshalb ein eigenes Simulationsmodell entwickelt werden musste. Zunächst werden im Rahmen einer Einführung beide Systeme vorgestellt. Ein Abschnitt beinhaltet eine Ausführung zum Simulationsmodell und Erläuterungen zu seinen Eigenheiten. Abschließend folgen Ergebnisse von Parameterstudien, eine Interpretation der Ergebnisse sowie Schlussfolgerungen und die Optimierung der neuartigen Dämmsysteme.Evaluation and optimization of switchable insulation using the climatic conditions of Vienna. There have been numerous efforts to reduce CO2 emissions in recent years. Terms such as ”more economical”, ”more efficient”, and ”more effective” are often used in discussion of this theme. The field of building physics can make a significant contribution to energy efficiency since building heating and cooling produces a significant portion of overall hazardous greenhouse gases. In response, heat transfer coefficient limits are being set lower and lower resulting in thicker and more expensive insulation systems. Very creative systems are being developed and tested parallel to conventional solutions. This study examines and contrasts two of the systems focusing upon the heating and cooling requirements: the so called ”switchable insulation” and a new system called ”Thermocollect”. The systems cannot be compared using standard software programs as the calculations are based on steady‐state thermal conductivities. Therefore, an in‐house simulation model was developed. Both systems are described in the introduction. A presentation of the basic thermodynamic concepts applied in the simulation fol lows. One section contains an explanation of the simulation model and its distinctive properties. The study is concluded by the results of the parametric studies, an interpretation of the results and implications, and engineering optimizations for the new insulation systems.
Measures of prediction error for survival data with longitudinal covariates
Authors: Schoop Rotraut , Schumacher Martin , Graf Erika 
Published: February 2011

AbstractPrediction of future events using longitudinally collected patient measurements is increasingly popular as technical and methodological advances allow the construction of more and more complex prognostic models. We aim to give an overview of existing approaches to measure the prediction error of such dynamic predictions and link these to a measure proposed in a preceding paper (Schoop et al.), the conditional prediction error. We present theoretical results of the conditional prediction error, especially regarding the comparison of different prediction rules and its behavior in the presence of misspecification of the link between longitudinal covariates and survival time. A simulation study investigating the performance of its estimator in finite sample sizes rounds off this paper.

Abstract

Background
The aim of this retrospective matched cohort study was to evaluate the rate of recurrence among women with delayed large flap breast reconstruction after mastectomy for breast cancer. The recurrence rate among women treated at a single hospital was compared with that in an individually matched control group of women with breast cancer who did not have reconstruction after mastectomy.

Methods
Between 1982 and 2001, 125 women with previous invasive breast carcinoma underwent delayed large flap breast reconstruction with pedicled musculocutaneous or microvascular flaps (a median of 32 months after mastectomy). They were matched individually with 182 women with breast cancer who had a mastectomy but did not undergo breast reconstruction. Matching criteria were year of diagnosis, age at diagnosis and treating hospital. Medical records were evaluated until October 2007. Histopathological specimens for all included women were re-evaluated. The endpoint was locoregional or distant breast cancer recurrence. The risk of recurrent disease was calculated using a Cox proportional hazards analysis, adjusted for established prognostic factors.

Results
Median follow-up for the entire cohort was 146 months. The reconstruction group had a 2·08 (95 per cent confidence interval 1·07 to 4·06) times higher risk of recurrent disease than the mastectomy only group.

Conclusion
Women with breast cancer who had delayed reconstruction with a large flap in this study had a higher risk of recurrent disease than those with mastectomy alone.
Social dominance and the disassociation between explicit and implicit representations of equality
Authors: Harding Jessica F. , Sibley Chris G. 
Published: February 2011

AbstractThis study tested whether social dominance orientation (SDO) predicted a conceptual disassociation between explicit (declarative or propositional) attitudes about equality and implicit (automatic or associative) views of how representative New Zealand Europeans and Maori are of the New Zealand nation (N = 48 Europeans). Explicitly stated attitudes framing equality in terms of procedural justice or meritocratic treatment were positively correlated with individual differences in the implicit tendency to view New Zealand Europeans as exclusively representative of New Zealand. This tendency to explicitly frame equality as based on individual merit and to implicitly favour the dominant (European) ethnic group as representative of the nation was observed only among people high in SDO. Our analysis provides novel support for the position that meritocratic ideology is malleable and may be employed by those high in SDO to frame concepts of equality and justice in ways that suit their desire for group‐based dominance.

Published: February 2011

AbstractRhizosphere microorganism is an important bio‐component for wastewater treatment in constructed wetlands (CWs). Microbial abundance and enzyme activities in the rhizospheres of nine plant species were investigated in an integrated vertical‐flow CW. The abundance of denitrifiers, as well as urease, acid, and alkaline phosphatase activities were positively correlated to plant root biomass. The abundance of bacteria, fungi, actinomycetes, ammonifiers, denitrifiers, and phosphorus decomposers, related to nutrient removal efficiencies in CWs, greatly varied among rhizospheres of different plant species (p < 0.05). Significant differences in rhizosphere enzyme activity among plant species were also observed (p < 0.05), with the exception of catalase activity. The principal component analysis using the data of microbial abundance and enzyme activity showed that Miscanthus floridulus, Acorus calamus, and Reineckia carnea were candidates to be used in CWs to effectively remove nitrogen and phosphorus from wastewater.

AbstractThe chemokine receptor CXCR4 is a member of the seven transmembrane GPCR family, which is implicated in multiple diseases, including HIV infection, cancers, and rheumatoid arthritis. Low‐molecular‐weight nonpeptidic compounds, including AMD3100 and various pyridyl macrocyclic zinc(II) complexes, have been identified as selective antagonists of CXCR4. In the present study, structure–activity relationship studies were performed by combining the common structural features of alkylamino and pyridiyl macrocyclic antagonists. Several new zinc(II) or copper(II) complexes demonstrated potent anti‐HIV activity, strong CXCR4‐binding activity, and significant inhibitory activity against Ca2+ mobilization induced by CXCL12 stimulation. These results may prove useful in the design of novel CXCR4 antagonists, and the compounds described could potentially be developed as therapeutics against CXCR4‐relevant diseases or chemical probes to study the biological activity of CXCR4.

AbstractObjectiveType 2 diabetes disease management programmes (DDMPs) are offered by German social health insurance to promote healthcare consistent with evidence‐based medical guidelines. The aim of this study was to compare healthcare quality and medical endpoints between diabetes management programme participants and patients receiving usual care designated as controls.MethodsAll patients with type 2 diabetes (age range: 36–81) in a cross‐sectional survey of a cohort study, performed by the Cooperative Health Research in the Region of Augsburg, received a self‐administered questionnaire regarding their diabetes care. Physical examination and laboratory tests were also performed. The analysis only included patients with social health insurance and whose participation status in a diabetes disease management program was validated by the primary physician (n = 166). Regression analyses, adjusting for age, sex, education, diabetes duration, baseline waist circumference and clustering regarding primary physician were conducted.ResultsEvaluation of healthcare processes showed that those in diabetes disease management programmes (n = 89) reported medical examination of eyes and feet and medical advice regarding diet [odds ratio (OR): 2.39] and physical activity (OR: 2.87) more frequently, received anti‐diabetic medications (OR: 3.77) and diabetes education more often (OR: 2.66) than controls. Both groups had satisfactory HbA1c control but poor low‐density lipoprotein cholesterol control. Blood pressure goals (<140/90 mmHg) were achieved more frequently by patients in diabetes disease management programmes (OR: 2.21).ConclusionsGerman diabetes disease management programmes are associated with improved healthcare processes and blood pressure control. Low‐density lipoprotein cholesterol control must be improved for all patients with diabetes. Further research will be required to assess the long‐term effects of this diabetes disease management programme. Copyright © 2011 John Wiley & Sons, Ltd.

Strategies for the reduction of 3‐MCPD esters and related compounds in vegetable oils
Authors: Matthäus Bertrand , Pudel Frank , Fehling Peer , Vosmann Klaus , Freudenstein Anne 
Published: February 2011

AbstractFor the reduction of 3‐monochloro‐1,2‐propanediol fatty acid esters (3‐MCPD esters) and related compounds in edible fats and oils three different strategies are conceivable: removal of critical reactants from the raw material, changing of the refining process or removal of formed 3‐MCPD esters and related compounds from the refined product. This paper discusses these possibilities and shows that different raw materials have different capabilities to form 3‐MCPD esters and related compounds, whereas palm oil, but also corn oil or coconut oil possess the highest potential for the formation. Washing of the raw material before the refining process with water or ethanol (75%) reduced the capability for the formation of 3‐MCPD esters and related compounds in palm oil for about 20 and 25%, respectively. The paper shows that chloride and DAGs seem to be important precursors for the formation of 3‐MCPD esters and related compounds. A hypothesis was defined that a content of 4% DAGs could be a threshold for a higher potential of the raw material for the formation of the esters. Using acid solutions (formic acid) instead of water for the generation of strip steam during deodorization resulted in a reduction of the formation of glycidyl esters for about 35%.Practical application: In a first statement the German Federal Institute for Risk Assessment (BfR) but also others recommended to search for alternative techniques for the production of edible oils to ensure lower levels of 3‐MCPD esters and related compound. Changing the selection criteria for the raw material, improving the raw material before refining or removal of 3‐MCPD esters and related compounds after refining have the advantage that the refining process which has been optimized over the last 100 years regarding oil quality does not need to be changed.
Negotiating dual identities: The impact of group‐based rejection on identification and acculturation
Authors: Badea Constantina , Jetten Jolanda , Iyer Aarti , Er‐rafiy Abdelatif 
Published: February 2011

AbstractWe propose that to understand how rejection perceptions affect immigrants' acculturation orientations, we need to take account of perceptions of rejection and group identification with both the host society and the country of origin. In line with previous work, we found among Romanians and Moroccan immigrants in France that perceived French rejection directly affected French identification and acculturation orientations. In addition, perceived rejection by the country of origin (Romanians and Moroccans in the country of origin) negatively affected immigrants' identification with this group. In turn, identification with the country of origin positively predicted endorsement of integration and separation orientations, and negatively predicted endorsement of assimilation. Overall, results suggest that identification with the country of origin is an additional important factor in determining acculturation decisions. Copyright © 2011 John Wiley & Sons, Ltd.
