Das Materielle der Gefühle: Aufwachsen in familialen Dingwelten
Authors: Nohl Arnd-Michael 
Published: February 2012

Zusammenfassung
So wichtig materielle Dinge für die menschliche Sozialisation sind, so schwierig ist es, ihre Konstitution in der Erfahrungswelt von kleinen Kindern zu erklären. In diesem Beitrag wird mit dem philosophischen Pragmatismus (James, Mead, Dewey) die Dingkonstitution wie auch die emotionale Qualität der Dingerfahrung reflektiert. Anhand der Kindheitserinnerungen von Literaten und Literatinnen aus der Türkei und Deutschland werden diese theoretischen Einsichten exemplarisch vertieft. Deutlich wird dabei die hohe Relevanz von materiellen Dingen für die emotionale Grundierung des eigenen Weltbezugs.
Nostalgia Overdose. Homesickness in Wedding Ceremonies of the Turkish-German Community in Berlin
Authors: Ergun Köken 
Published: February 2012

Abstract
Having a focus on wedding rituals of the Turkish communities in Berlin, this research is based on the ways in which rituals strengthen community bonding within immigrants away from their homeland. When done periodically, such rituals reassure social connections within immigrant communities, while creating borders to keep others outside. Unlike weddings in Turkey, those in Germany are performed in purpose-built indoor spaces, isolated from the German community. This voluntary isolation enables the restaging of cultural codes and forms of the homeland, which often results in excess of emotions related to nostalgia. This in turn mutates cultural symbols for younger members of the immigrant community and paves the way to confused identities.
Unzählbare Schönheit. Für eine Poetik des Interkulturellen
Authors: Wahbi Hassan 
Published: February 2012

Zusammenfassung
In diesem Beitrag möchte ich zurückkommen auf die Frage nach der Erweiterung des Ich im Laufe eines Lebens, welches mehrfältig ist oder wird; es ist dies eine Variante dessen, was ich schon in früheren Texten vorschlug (L’art dialogique, Alexandria 2006; L’apprentissage négatif, Tunis 2008; Hybride toi-même, Casablanca 2009) bezüglich der notwendigen Labilität des Ich, d. h., dass der mehrfältige Mensch nicht mehrfältig ist in seiner Dispersion, sondern im Erarbeiten seiner Redefinition. Alles neu Erworbene bedingt, was er ist und stellt ihn vor etwas Weiteres. Eine Art der Vervollkommnungsmöglichkeit auf persönlichem Niveau, nicht moralisch, sondern eher als Vision der Dinge und des Selbst. Dieses Mal gehe ich von einer weniger verdeckten Subjektivität aus, falls ich das je zu tun versäumte, denn Erfahrung speist sich ja ununterbrochen aus einer interkulturellen Wunde, die sich als Sollbruchstelle träumt.

ABSTRACTIn this work was studied the effect of silicon content from 0.5 to 3 wt.% Si on the macrostructure of casting ingots. Fe-Si alloys with low contents of impurities were produced in electric induction furnace under inert atmosphere. Castings of 12.5 cm thick, 25 cm long and 30 cm high were obtained of each alloy poured into metallic mould. The ingots obtained were sectioned in slices of 12 cm wide, 25 cm high and 2 cm thick, the central slice of each ingot was prepared metallographically to reveal the macrostructure of the six cast alloys. The results indicate that alloys with low silicon levels (0.5 and 1.0% Si) and with small solidification intervals have relatively fine equiaxed grains, while alloys with higher silicon content and a higher solidification intervals present predominantly columnar grains. These macrostructures are not the usually structures linked to short and long freezing range. Another important result is the absence of dendritic structure usually present in cast alloys.

Authors: Leng Zhe , Field David P. 
Published: February 2012

ABSTRACTFerritic/martensitic steels such as HT9 steel, is used for structural components in nuclear power plants because of its high strength and good swelling resistance. Understanding the mechanical behavior of these steels is quite important, since it will affect the strength and the life of the component. In this study, a dislocation density based crystal plasticity finite element model is developed in which different types of dislocation evolves on the activated 12 slip systems in alpha-iron. The dislocation evolves in the form of closed loop and the dislocation density is tracked as internal state variable, the generation and annihilation of dislocations are modeled based on the dislocation interaction laws. The plastic flow is calculated based on the dislocation densities and a generalized Taylor equation is used as the hardening law, and the hardening is assumed to be isotropic in this study. The evolution of polycrystal texture of alpha-iron is presented in the form of pole figures, which indicate the orientation spread and agree with the experimental result. The model also indicates the inhomogeneous dislocation distribution and stress concentration at the grain boundaries.

Published: February 2012

ABSTRACTPhotoelectrodeposition of copper on boron-doped diamond films (BDD) was investigated. In this work, two different doped films were analyzed. Copper particles were deposited in the potentiostat mode and under UV irradiation. The BDD film as-grown and the BDD film modifed with Cu (Cu/BDD) on the surface were characterized by Raman Spectroscopy and Scanning Electron Microscopy (SEM) respectivily. These electrodes were tested as electrocatalysts for nitrate reduction in Britton-Robinson buffer solution (pH=3). Electrochemical measurements showed that the electrode with high doping level displayed the best electrocatalytic activity.
Easily altered minerals and reequilibrated fluid inclusions provide extensive records of fluid and thermal history: gypsum pseudomorphs of the Tera Group, Tithonian-Berriasian, Cameros Basin
Authors: González-Acebrón Laura , Goldstein Robert , Mas Ramon , Arribas Jose 
Published: February 2012

Abstract
This study reports a complex fluid and thermal history using petrography, electron microprobe, isotopic analysis and fluid inclusions in replacement minerals within gypsum pseudomorphs in Tithonian-Berriasian lacustrine deposits in Northern Spain. Limestones and dolostones, formed in the alkaline lakes, contain lenticularly shaped gypsum pseudomorphs, considered to form in an evaporative lake. The gypsum was replaced by quartz and non-ferroan calcite (Ca-2), which partially replaces the quartz. Quartz contains solid inclusions of a preexisting non-ferroan calcite (Ca-1), anhydrite and celestine.
High homogenization temperatures (T
h) values and inconsistent thermometric behaviour within secondary fluid inclusion assemblages in quartz (147–351°C) and calcite (108–352°C) indicate high temperatures after precipitation and entrapment of lower temperature FIAs. Th are in the same range as other reequilibrated fluid inclusions from quartz veins in the same area that are related to Cretaceous hydrothermalism.
Gypsum was replaced by anhydrite, likely during early burial. Later, anhydrite was partially replaced by Ca-1 associated with intermediate burial temperatures. Afterward, both anhydrite and Ca-1 were partially replaced by quartz and this by Ca-2. All were affected during higher temperature hydrothermalism and a CO2-H2O fluid. Progressive heating and hydrothermal pulses, involving a CO2-H2O fluid, produce the reequilibration of the FIAs, which was followed by uplift and cooling.

Published: February 2012

Orally Administered Melatonin and the Accumulation and Toxicity of Cadmium in the Bank Vole (Myodes Glareolus)Animal gender and age significantly influence the accumulation and toxicity of heavy metals, including cadmium (Cd). The aim of this study was to determine the effect of orally administered melatonin (6 μg/ml), a known antioxidant and metal chelator, on Cd accumulation and toxicity in one month old females and males (young) and five months old bank voles (old) exposed to dietary Cd (100 μg/g) for six weeks. Compared to the Cd alone group, melatonin co-treatment brought about a decrease of Cd concentration in the liver (17% and 20%) and kidneys (39% and 36%) of young female and male bank voles, respectively, while in old animals increased Cd accumulation in liver (65%) and kidneys (81%) and enhanced consumption of Cd-contaminated food (136%) without any effect on their body mass. The results suggest that orally administered melatonin together with cadmium in young bank voles reduces tissue Cd accumulation possibly through forming stable complexes with this metal but in older rodents, melatonin increases concentration of the metal through increasing consumption of Cd-contaminated food.
Regularities of Variation of the Red Blood Indices Characterizing the Respiratory Function of Blood in Selected Fish
Authors: Maciak Sebastian , Kostelecka-Myrcha Alina 
Published: February 2012

Regularities of Variation of the Red Blood Indices Characterizing the Respiratory Function of Blood in Selected FishThere is a large diversity of red blood indices determining oxygen transport ability in vertebrates. In fish this diversity is particularly large, probably due to the great variability in water environments, which impedes the possibility of finding and understanding general patterns. It has been assumed that in mammals, the measure determining the ability of a blood unit to transport oxygen is the ratio of hemoglobin concentration (HB) and total erythrocyte surface area (TSAE). It was also shown that both in mammals and birds the amount of hemoglobin per total surface area unit (Hb/TSAE) conditions maximum use of respiratory pigment in oxygen transport, in different physiological and environmental conditions. In order to check whether this regularity occurs in fish, red blood indices were analyzed in seven species of freshwater fish, differing noticeably in their biology and body mass in two seasons of the year. Notwithstanding this marked seasonal variability to the component variables together determining the total surface area of erythrocytes, the value for TSAE was found to differ in proportion to the higher or lower concentrations of HB. In consequence, the HB/TSAE ratio indicative of the maximal use of haemoglobin in the transport of oxygen was constant in all of the fish studied between analyzed seasons. This constancy - resembling that to be noted in birds - is most probably related to the counter-current gaseous exchange ongoing in the gills of fish.

The Common Hamster,Cricetus Cricetus(L.) Populations in the Lower San River ValleySeven active localities of the common hamster were found in the Lower San River Valley, while in the Tarnogród Plateau the hamsters are not present any longer. The populations on both banks of the San River belong to the Pannonia phylogeographic lineage. The contact between two Polish phylogeographic lineages: E1 and Pannonia, was not found in this area. Although it is not possible to establish currently what was the former distribution of the phylogroups, it is probable that the barrier between them was formed by the Solska Forest. The genetic diversity of the common hamster populations in the Lower San River Valley is lowered, however quite typical for Polish Pannonia populations. The populations of the Lower San River Valley are isolated from the other parts of the species range in Poland. The only possible connection with other populations is through Ukrainian hamsters in Lvov district.
Expansion du marché mondial du gaz naturel liquéfié et stratégies des acteurs. Étude comparative des stratégies algérienne, qatarie et russe
Authors: Senouci Benabbou 
Published: February 2012

Résumé Depuis les années soixante du vingtième siècle, l’industrie gazière a affirmé son rôle majeur comme source énergétique à l’échelle mondiale. Ce travail est une étude comparative entre trois pays exportateurs de Gaz Naturel Liquéfié (GNL) : l’Algérie, le Qatar et la Russie. L’essor du marché du gaz naturel a conduit ces trois pays à investir fortement dans ce secteur (à des degrés différents), afin d’accroître leurs productions. Au-delà du discours de l’OPEP sur le gaz, les faits montrent qu’entre les trois pays il y a plus de concurrence et de compétitivité que de coopération pour le devenir de cette OPEP du gaz, l’Algérie jette la pierre au Qatar et la Russie en leur qualité de plus grands exportateurs de gaz naturel au monde ; les stratégies des trois pays ne convergent pas pour le moment.

Nuclear to Cytoplasmic Translocation of Heterogeneous Nuclear Ribonucleoprotein U Enhances TLR-Induced Proinflammatory Cytokine Production by Stabilizing mRNAs in Macrophages

Published: February 2012

Abstract
TLR signaling is associated with the transcription of various proinflammatory cytokines, including TNF-α, IL-6, and IL-1β. After transcription, the mRNA of these proinflammatory cytokines needs to be tightly controlled at the posttranscriptional level to achieve an optimal expression. However, the precise mechanism of posttranscriptional regulation is not fully understood. In the current study, we found the expression of heterogeneous nuclear ribonucleoprotein U (hnRNP U), also termed scaffold attachment factor A, was greatly induced by TLR stimulation in macrophages. Knockdown of hnRNP U expression greatly attenuated TLR-induced expression of TNF-α, IL-6, and IL-1β, but not IL-12, whereas hnRNP U overexpression greatly increased TLR-induced expression of TNF-α, IL-6, and IL-1β. Furthermore, hnRNP U knockdown accelerated the turnover and decreased the t1/2 of TNF-α, IL-6, and IL-1β mRNA. RNA immunoprecipitation demonstrated that hnRNP U bound to the mRNA of these proinflammatory cytokines through the RGG motif. Importantly, we showed that TLR stimulation provided a stimulus for hnRNP U nuclear to cytoplasmic translocation. Therefore, we propose that hnRNP U induced by TLR signaling binds to the mRNA of a subset of proinflammatory cytokines and positively regulates the expression of these cytokines by stabilizing mRNA.

Abstract
Ongoing inflammation including activation of the complement system is a hallmark of systemic lupus erythematosus (SLE). Antimicrobial neutrophil extracellular traps (NETs) are composed of secreted chromatin that may act as a source of autoantigens typical for SLE. In this study, we investigated how complement interacts with NETs and how NET degradation is affected by complement in SLE patients. We found that sera from a subset of patients with active SLE had a reduced ability to degrade in vitro-generated NETs, which was mostly restored when these patients were in remission. Patients that failed to degrade NETs had a more active disease and they also displayed lower levels of complement proteins C4 and C3 in blood. We discovered that NETs activated complement in vitro and that deposited C1q inhibited NET degradation including a direct inhibition of DNase-I by C1q. Complement deposition on NETs may facilitate autoantibody production, and indeed, Abs against NETs and NET epitopes were more pronounced in patients with impaired ability to degrade NETs. NET-bound autoantibodies inhibited degradation but also further increased C1q deposition, potentially exacerbating the disease. Thus, NETs are a potent complement activator, and this interaction may play an important role in SLE. Targeting complement with inhibitors or by removing complement activators such as NETs could be beneficial for patients with SLE.
Galectin-1 Triggers an Immunoregulatory Signature in Th Cells Functionally Defined by IL-10 Expression

Published: February 2012

Abstract
Galectin-1 (Gal-1), a β-galactoside–binding protein, can alter fate and effector function of Th cells; however, little is known about how Gal-1 induces Th cell differentiation. In this article, we show that both uncommitted and polarized Th cells bound by Gal-1 expressed an immunoregulatory signature defined by IL-10. IL-10 synthesis was stimulated by direct Gal-1 engagement to cell surface glycoproteins, principally CD45, on activated Th cells and enhanced by IL-21 expression through the c-Maf/aryl hydrocarbon receptor pathway, independent of APCs. Gal-1–induced IL-10+ T cells efficiently suppressed T cell proliferation and T cell-mediated inflammation and promoted the establishment of cancer immune-privileged sites. Collectively, these findings show how Gal-1 functions as a major glycome determinant regulating Th cell development, inflammation, and tumor immunity.
Protecting Against Misleading Post‐event Information with a Self‐Administered Interview
Authors: Gabbert Fiona , Hope Lorraine , Fisher Ronald P. , Jamieson Kat 
Published: February 2012

SummaryTwo studies investigated whether an early recall opportunity, in the form of a self‐administered interview (SAI), reduced forgetting and protected against the negative consequences of post‐event misinformation. In both studies, participants viewed a simulated crime on DVD after which half immediately recorded their statement by using the SAI, whereas control participants did not have an immediate recall opportunity. Following a delay, participants were presented with misinformation encountered either in a misleading news report (Study 1) or in the form of misleading cued‐recall questions (Study 2). Results showed that participants who had completed a SAI after witnessing an event were significantly less prone to forgetting and significantly more resistant to the negative consequences of misinformation. The SAI was able to protect both the quantity and quality of information about a previously witnessed event. Applied implications are discussed. Copyright © 2012 John Wiley & Sons, Ltd.

Published: February 2012

SUMMARYThis paper considers decentralized stabilization problem for a class of large‐scale systems with interval time‐varying delays in interconnections. The time delay is assumed to be a continuous function belonging to a given interval but not necessary to be differentiable. On the basis of constructing a set of improved Lyapunov–Krasovskii functionals, new sufficient conditions for the existence of decentralized state feedback controller are established in terms of linear matrix inequalities. The decentralized control design guarantees the system exponential stability. An illustrative example is given to show the validity of the results obtained in this paper.

Effects of Divalent Metals on Nanoscopic Fiber Formation and Small Molecule Recognition of Helical Proteins
Authors: Gunasekar Susheel K. , Anjia Luona , Matsui Hiroshi , Montclare Jin K. 
Published: February 2012

AbstractMetal dependent protein‐based assemblies derived from the cartilage oligomeric matrix protein (C) coiled‐coil domain (His6‐C) and two variants with mutation at position 40 (His6‐T40A) and 44 (His6‐L44A) are explored. All proteins have an N‐terminal hexahistidine tag (His6) that interacts with divalent metal ions Zn(II) and Ni(II). Binding to Zn(II) confers enhanced helical structure and stability, while Ni(II) promotes aggregation. Surprisingly, His6‐L44A undergoes a conformational switch from unstructured to α‐helix in the presence of Zn(II). Both His6‐C and His6‐T40A further assemble into discrete nanofibers that appear to be stabilized by Zn(II) in which the fiber formation is dictated by the α‐helical content. Because Ni(II) promotes aggregation, the proteins visibly cluster, forming large fiber mats in the case of His6‐C and His6‐T40A or aggregated structures as observed for His6‐L44A. Due to the unique pentameric assembly of the proteins, recognition of a small molecule within the pore is assessed using curcumin as the guest molecule. In the presence of Zn(II), there is enhanced binding to curcumin, while the addition of Ni(II) causes a loss in binding. It is shown that metal binding serves as a trigger to control the conformation of the proteins, affecting the nanoscopic fibrous assemblies and small molecule recognition abilities.
