The Impact of Stent Graft Material on the Inflammatory Response After EVAR
Authors: Sartipy Fredrik , Lindström David , Gillgren Peter , Ternhag Anders 
Published: July 2015

Background: Patients undergoing endovascular aneurysm repair (EVAR) due to abdominal aortic aneurysm often develop an inflammatory response, postimplantation syndrome (PIS) where fever and leukocytosis are common. Previous studies suggest that type of stent graft material (polyester or polytetrafluoroethylene [PTFE]) plays a role. Objectives: To investigate the effect of stent graft material on the inflammatory response and length of hospital stay in patients undergoing standard elective EVAR. Methods: Sixty-nine elective EVAR patients were included in this observational study. To avoid comparing patients with a different graft location and stent graft burden, 12 cases were excluded as well as cases with complication or simultaneous open surgical procedures, leaving 45 patients (32 with polyester and 13 with PTFE graft) for final analysis. Tympanic temperature, C-reactive protein (CRP), white blood cell (WBC), and procalcitonin (PCT) were measured on days −1 and +1 and +3. Duration of in-hospital stay and frequency of PIS were recorded. Results: The PIS was diagnosed in 9 (28.1%) of the 32 polyester cases and in 1 (7.7%) of the 13 cases in the PTFE group ( P = .24). Median (interquartile range) in-hospital stay was 5 (5-6) days in the polyester group and 4 (4-5) days in the PTFE group ( P = .009). On day +3, in the polyester group, mean CRP was 154 (95% confidence interval: 127-182) mg/L, WBC 9.5 (8.4-10.5) ×109/L, and PCT 0.17 (0.12-0.21) ng/mL. In the PTFE group, mean CRP was 70 (32-109) mg/L ( P = .001), WBC 8.8 (6.4-11.1) ×109/L ( P = .37), and PCT 0.09 (0.06-0.13) ng/mL ( P = .009) on day +3. Conclusion: Standard EVAR with polyester stent grafts appears to result in a trend toward a more pronounced inflammatory reaction than similar EVAR using PTFE and is associated with a longer in-hospital stay.

Published: July 2015

Objectives The aim of this study was to examine the relationship between cartilage, ligament, and meniscus degeneration and radiographic alignment in severe varus knee osteoarthritis in order to understand the development of varus knee osteoarthritis. Design Fifty-three patients (71 knees) with primary varus knee osteoarthritis and who underwent total knee arthroplasty were selected for this study. There were 6 men and 47 women, with 40 right knees and 31 left knees studied; their mean age at operation was 73.5 years. The ligament, meniscus, degeneration of joint cartilage, and radiographic alignments were examined visually. Results The tibial plateau–tibial shaft angle was larger if the condition of the cartilage in the lateral femoral condyle was worse. The femorotibial angle and tibial plateau–tibial shaft angle were larger if the conditions of the lateral meniscus or the cartilage in the lateral tibial plateau were worse. Conclusion Based on the results of this study, progression of varus knee osteoarthritis may occur in the following manner: medial knee osteoarthritis starts in the central portion of the medial tibial plateau, and accompanied by medial meniscal extrusion and anterior cruciate ligament rupture, cartilage degeneration expands from the anterior to the posterior in the medial tibial plateau. Bone attrition occurs in the medial tibial plateau, and the femoro-tibial angle and tibial plateau–tibial shaft angle increase. Therefore, the lateral intercondylar eminence injures the cartilage of the lateral femoral condyle in the longitudinal fissure type. Thereafter, the cartilage degeneration expands in the whole of the knee joints.

An iterative method for split hierarchical monotone variational inclusions
Authors: Ansari Qamrul Hasan , Rehan Aisha 
Published: July 2015

AbstractIn this paper, we introduce a split hierarchical monotone variational inclusion problem (SHMVIP) which includes split variational inequality problems, split monotone variational inclusion problems, split hierarchical variational inequality problems, etc., as special cases. An iterative algorithm is proposed to compute the approximate solutions of an SHMVIP. The weak convergence of the sequence generated by the proposed algorithm is studied. We present an example to illustrate our algorithm and convergence result.
Questioned validity of Gene Expression Dysregulated Domains in Down's Syndrome
Authors: Do Long H. , Mobley William C. , Singhal Nishant 
Published: July 2015

Recently, in studies examining fibroblasts obtained from the tissues of one set of monozygotic twins (i.e. fetuses derived from the same egg) discordant for trisomy 21 (Down syndrome; DS), Letourneau et al., reported the presence of a defined pattern of dysregulation within specific genomic domains they referred to as Gene Expression Dysregulated Domains (GEDDs). GEDDs were described as alternating segments of increased or decreased gene expression affecting all chromosomes. Strikingly, GEDDs in fibroblasts were largely conserved in induced pluripotent cells (iPSCs) generated from the twin’s fibroblasts as well as in fibroblasts from the Ts65Dn mouse model of DS. Our recent analysis failed to find GEDDs. We reexamined the human iPSCs RNAseq data from Letourneau et al., and data from this same research group published earlier examining iPSCs from the same monozygotic twins. An independent analysis of RNAseq data from Ts65Dn fibroblasts also failed to confirm presence of GEDDs. Our analysis questions the validity of GEDDs in DS.

Published: July 2015

W niniejszym artykule przedstawiono dotychczasowe i przyszłe trendy rozwoju populacji miasta Poznania. Celem badań jest wskazanie powiązań i relacji między rozwojem demograficznym miasta i otaczających je obszarów podmiejskich w zakresie starzenia się ludności, rynku pracy i poziomu wykształcenia.Zmniejszenie średniego rocznego tempa wzrostu liczby ludności w powiecie poznańskim oraz towarzyszący mu spadek liczby mieszkańców Poznania wskazują na fazę absolutnej dezurbanizacji w rozwoju miasta. Trudno jest określić wpływ nieco większego wzrostu płodności kobiet w Poznaniu, w porównaniu z obserwowanym w otaczającym miasto regionie. Z kolei zmiany w długości oczekiwanego trwania życia wskazują rosnące podobieństwa charakterystyk rozwoju demograficznego miasta i strefy podmiejskiej.Procesy demograficzne są analizowane w powiązaniu ze zmianami społecznymi. Tempo wzrostu liczby absolwentów wyższych uczelni w najbliższym otoczeniu Poznania jest znacznie wyższe aniżeli obserwowane w centrum miasta. Zwrócono także uwagę na wpływ wykształcenia na rozwój kariery i wydłużenie okresu aktywności zawodowej, a także na decyzje matrymonialne i prokreacyjne. Wzrost poziomu wykształcenia siły roboczej ma stały, pozytywny i znaczący wpływ na wzrost gospodarczy.
Screening of juvenile Pinus radiata wood by means of Py-GC/MS for compression wood focussing on the ratios of p-hydroxyphenyl to guaiacyl units (H/G ratios)

Published: July 2015

Abstract
Analysis of thin slivers of juvenile (2-year-old) pine wood by pyrolysis-gas chromatography-mass spectrometry (Py-GC/MS) was explored as a fast and high-throughput method to assess compression wood (CW) via the ratio of the p-hydroxyphenyl to guaiacyl units (H/G ratio). Various chemical parameters such as contents of lignin, galactose, and p-hydroxyphenyl (H) units have been related to the CW in the tissue. The H/G ratio was calculated from all identified H and G lignin-derived pyrolysis products. The H/G ratio ranged between 0.019 and 0.052 for normal wood (NW) and between 0.133 and 0.227 for CW. There was a weak correlation between CW H/G ratio and Klason lignin content (R
2=0.4), but it was not correlated to the galactose content. Lignin- and carbohydrate-derived pyrolysis products were subjected to principal component (PC) analysis. The first two PCs discriminate the CW from the NW, accounting for about 41% of the total variance in the dataset. The model developed based on lignin-derived peaks explained 54% of the variance.

Published: July 2015

AbstractEffects of temperature and slag composition on dephosphorization in a 120 ton top-bottom combined blown converter steelmaking process by double slag method were studied. The slag properties were determined by scanning electron microscope- energy dispersive spectrometry (SEM-EDS), X-ray diffraction (XRD). The results show that the transition oxidation temperature between dephosphorization and decarbonization Tf is not the favorable temperature for the first deslagging. The optimum first deslagging temperature is confirmed to be approximately 1,673 K which is about 70 K higher than Tf. High melting temperatures phases (such as 3CaO·SiO2) in the slag with high basicity and MgO content are unfavorable to the dephosphorization. The optimum process condition for dephosphorization at the first deslagging in present work is approximately 1,673 K in temperature, 2.0 in slag basicity, 6 and 17 mass% in MgO and T.Fe content, 6 mass% ≤ MnO content.

Published: July 2015

Abstract
The microstructure of as-cast and as-HIPed (hot isostatic pressed) K403 superalloy was investigated using a scanning electron microscopy (SEM), as component analysis was conducted by energy dispersive x-ray spectrometer (EDS). It was found that the microstructure of the alloy was improved significantly through HIP. Firstly, the microporosity and micropores in as-cast alloy were ameliorated effectively and the morphology of grains tended to be uniform. Moreover, the morphology of carbides at grain boundaries transformed from thread-like to granular. Uppermost, the size, shape and volume fraction of γ′ phase were significantly optimized and γ′ precipitates in two different sizes were generated in matrix. Nanoindentation experiment was then carried out to obtain the nanohardness and elastic modulus of as-cast and as-HIPed K403 superalloy. The results revealed an obvious increase in both nanohardness and elastic modulus after HIP. Conclusions could be drawn from the research that HIP could improve the microstructure of as-cast K403 superalloy, which could enhance the mechanical properties of the alloy positively.

O4 ferrites (where x = 0–1.0) were prepared by solid-state reaction. The effects of Cr content on structural and magnetic properties were investigated. X-ray diffraction (XRD) revealed the formation of ferrite particles with cubic spinel structure. The lattice parameter and average crystallite sizes are much dependent on the chromium content and are found to decrease with its increasing. The initial permeability (μ

Abstract
With the rapid development of power grid construction, appropriate maintenance can bring great benefits to the electricity company. On the contrary, it will cause sacrifices, even effect the development of economy. Thus, electrical equipment condition-based maintenance plays a key role to assure healthy operation of electrical equipment and improve power supply reliability. Under the background, in this paper, we combine the Cloud Model with TOPSIS which is improved by Grey Correlation Theory and propose a new decision-making method for electrical equipment condition-based maintenance. In this method, Cloud Model is used to solve the fuzziness and randomness of uncertain linguistic sets in the progress of decision-making. At the same time, we integrate the grey correlation degree into TOPSIS, and calculate the comprehensive relative closeness. Through the numerical example and comparing the sensitivity of some related methods about decision-making, the method in this is proved to be credibility. The basis of electrical equipment condition-based maintenance decision-making can be provided and supply dispatcher decision-making reference when arrange the CBM plan.
Zum Gravitationsgesetz bei Newton, Kant und Fries
Authors: Görg Erdmann 
Published: July 2015

Abstract:This article examines the development of the law of gravitation in the writings of Isaac Newton, Immanuel Kant and Jakob Friedrich Fries. Fries was a philosopher, mathematician and physicist who stood in the Kantian tradition, but who nevertheless had empiricist leanings. Whereas the development of the law of gravitation is well explored as regards Newton and Kant, the heuristic interpretation of the Kantian ‘fundamental forces’ carried out by Fries has not yet received the scholarly attention it deserves. In the following, I will elaborate on how Newton, Kant and Fries developed the law of gravitation and how it was incorporated in their natural philosophies.
Does Discrimination Require Disadvantage?
Authors: Horta Oscar 
Published: July 2015

Abstract
In standard cases of discrimination the interests of the discriminatees are considered comparatively worse than those of others. Accordingly, discrimination is often defined as some form of differential consideration or treatment which, among other features, entails a disadvantage for discriminatees. There are some apparent forms of nonstandard discrimination, however, in which it seems that this need not occur. This paper examines three of them: epistemic discrimination, discrimination against entities unable to be harmed by it and nonhierarchical segregation. If, as it seems, these really are forms of discrimination that means standard definitions may fail or must be reinterpreted. There is a way to account for the mentioned nonstandard forms of discrimination by claiming that all forms of worse consideration or treatment can be considered discriminatory. This, however, entails interpreting the term “worse” in a very broad manner, and some may not find this solution intuitive. Despite this, the paper will argue that alternative accounts entail more serious problems.
Film space as mental space
Authors: Dunat Silvana 
Published: July 2015

AbstractThis paper explores the hypothesis that the three-dimensionality and continuity of film space is a mental construct based on our perception of the images projected on the screen and our knowledge of/about the world and our knowledge of/about film. Starting from Alberti’s (1804 [1435]) visual pyramid as a geometric representation of the vision of a stationary observer, such as a painter, and Gardies’ (1993) mirror ball representing the vision of a dynamic spectator, such as a camera, the paper proposes a new schema aiming to explain how the three spaces – real, virtual, and mental – participate in the construction of film meaning.
Kenneth L. Pike and science fiction
Authors: Gorlée Dinda L. 
Published: July 2015

AbstractKenneth L. Pike’s tagmemic explanation of his etic-emic equivalence corresponds to the notion of “approximate” translation. According to a weaker version of the Sapir-Whorf hypothesis, Pike’s cross-cultural and multilingual perspective of Bible translation approximates the duality and triadicity of Peirce’s immediate/emotional, dynamical/energetic, and final/logical interpretants. Pike’s astronautical examples of the artificial language Kabala-X translated into English and the science fiction story of the Earthmen who invaded Mars are fictional and creative artifacts of human-alien cryptography leading, as argued here, to false semio-logical reasoning.

Zwischen Schah und Khomeini
Authors: Bösch Frank 
Published: July 2015

Vorspann
1978/79 fegte eine Revolution das Regime von Schah Mohammad Reza Pahlavi im Iran hinweg - eine islamische Revolution, an deren Ende ein Gottesstaat unter Führung der Geistlichkeit stand, mit Ayatollah Khomeini an der Spitze. Die Bundesregierung unter Kanzler Helmut Schmidt und Außenminister Hans-Dietrich Genscher befand sich in einer Zwickmühle: Einerseits war der Iran ein wichtiger Erdöllieferant und Handelspartner, andererseits verstörte die Gewalt gegen politische Gegner und Vertreter der westlichen Staatengemeinschaft, die in der Besetzung der amerikanischen Botschaft in Teheran gipfelte. Frank Bösch zeigt auf der Basis neuer Quellen, wie die Bundesregierung auf die islamische Revolution reagierte, zwischen interessengeleitetem Pragmatismus und außenpolitisch gebotener Bündnistreue zu den USA lavierte und so hinter den Kulissen als Vermittler zwischen Teheran und Washington fungieren konnte.
Die italienische Zeitgeschichtsforschung
Authors: Dipper Christof 
Published: July 2015

Vorspann
Die Aussichten sind trübe, polemische Insider sprechen sogar von einem „Selbstmord“ der italienischen Universitäten und meinen damit auch die Zeitgeschichte südlich der Alpen. Christof Dipper, hochgeschätzter Veteran der deutschen Italienforschung, konnte sich als Mitglied einer Art Evaluierungskommission selbst ein Bild von der Lage der italienischen Zeitgeschichte machen. Es gibt, so betont er in seiner luziden Analyse, kaum Anlass zu Optimismus: Selbstreferenzialität, Provinzialität und methodischer Traditionalismus wohin man schaut, und nur wenige helle Tupfer, die von Wagemut und Innovationskraft zeugen.
Gefangen in der analytisch-normativen Westernisierung der Zeitgeschichte
Authors: Hoeres Peter 
Published: July 2015

Vorspann
Der Tübinger Historiker Anselm Doering-Manteuffel hat in den Vierteljahrsheften für Zeitgeschichte vor kurzem sein Konzept der Zeitbögen vorgestellt. Er bietet damit ein politische Zäsuren übergreifendes, an handlungssteuernden Ideen orientiertes Deutungsmuster an, um die deutsche Geschichte im 20. Jahrhundert zu verorten. Peter Hoeres nimmt das Konzept der Zeitbögen kritisch unter die Lupe, hinterfragt seine normativen Implikationen, wägt analytisches Potenzial und inhaltlich- methodische Blindstellen gegeneinander ab und zeigt Perspektiven für alternative Interpretationen auf.

Tim B. Müller hat mit seinen provokanten Thesen - nicht ganz unbeabsichtigt und nicht ganz überraschend - eine heftige Debatte über das Scheitern der Weimarer Republik ausgelöst. Seine Kritik an älteren Deutungen wird nun ihrerseits auf den Prüfstand gestellt. Überzeugen seine Argumente oder sind sie nur alter Wein in neuen Schläuchen, wie manche meinen? Steffen Kailitz, Mitarbeiter am Hannah-Arendt- Institut in Dresden, bezieht aus politologischer Sicht Stellung.
