The Gaps We Choose to Fill and How We Choose to Fill Them: Readers\u27 Creation of Turkish German Identity in Texts by Zehra Çirak
No full textThis thesis explores why readers insist on interpreting Zehra Çirak\u27s texts in light of her Turkish German background when she claims that her texts have little to do with her Turkish heritage and are more universally applicable. While readers can interpret her texts without considering the author\u27s biography, thereby obtaining insights into their own personal identity, I suggest that it also makes sense for readers to interpret her texts with the author\u27s biography in mind because of current events and the history of Turkish migrant labor in Germany. To explore different possible interpretations of her texts, I have categorized Çirak\u27s poetry, found in four of her volumes of poetry, Vogel auf dem Rücken eines Elefanten (1991), Fremde Flügel auf eigener Schulter (1994), Leibesübungen (2000), and In Bewegung (2008), into two broad groups. First, I look at the few poems in which Çirak overtly addresses alterity by discussing the alienation of Turks. In these texts, the speakers use Turkish words or images that link the texts to Çirak\u27s biography. Then I turn to look at poems that can only metaphorically be interpreted as addressing Turkish German integration into mainstream German society and discuss how even though the figurative language Çirak employs make her texts applicable to other situations or interpretations, the texts lend themselves to being read in light of multiculturalism. In both of these categories of poetry, Çirak uses metaphor to address alterity without pandering to stereotypes or setting categorical limits on Turks, Germans, or other members of her readership
Surface and Material Modifications of Tempered Steel after Precision Grinding with Electroplated Coarse Grained Diamond Wheels
No full textAbstractOne particular kind of engineered grinding wheels are precisely profiled grinding tools with flattened coarse diamond grains, primarily used for machining of brittle materials. Because of their grain geometries, they are also expected to introduce mechanical strains into steel workpieces generating a work hardening effect. Also low surface roughnesses combined with favorable compressive residual stresses are targeted. In this paper the feasibility of this process technology is investigated and possible adverse aspects are identified. These findings can be used in future to further develop the process towards higher forces and speeds and thus conditions close to industrial applications in conventional grinding of steel parts
Electron Microscopic Characterization of Mechanically Modified Surface Layers of Deep Rolled Steel
No full textAbstractProcess Signatures describe the relationship between the applied material loads and the resulting surface modification according to the predominant effect of the production process used. This approach is supposed to allow the adjustment of surface layer properties prior to the production process. In this paper, the surface modifications of turned, turned + deep rolled and deep rolled metastable austenitic steel with predominantly thermo-mechanical/ mechanical effects are analyzed by electron microscopic methods like Electron Backscatter Diffraction (EBSD) and Transmission Electron Microscope (TEM) analysis. The modified surface layers show an increase in hardness as a result of the induced Hertzian pressures. TEM investigations of FIB-lamellae cut from the surface zone of the turned/ turned + deep rolled workpiece reveal a nanocrystalline microstructure. A superposition of surface modifications from turning and deep rolling is identified in the turned + deep rolled workpiece
A Trinitarian Ecclesiology of Communion and the Mission of the Church: Beyond the Debate between Joseph Cardinal Ratzinger and Leonardo Boff: The Contribution of Bernd Jochen Hilberath
No full textThe quotation above, from Called to Be Catholic: Church in a Time of Peril, a statement released by Joseph Cardinal Bernardin and the Catholic Common Ground Project in August of 1996, draws attention to the polarization that marks the state of the Catholic Church in the United States. This polarization is marked, to a great extent, by the use of labels such as neo-conservative, conservative, moderate, and liberal, to define theological views on topics ranging from how to celebrate the eucharist to the role of women in the Church to the relation between the local church and the universal Church to the way in which the Church engages in socio-political issues. The statement laments the fact that proposals offered in the hope of advancing dialogue on a particular issue are often subject to ideological litmus tests and are placed within certain pre-existing camps, without a second thought given to their potential contribution to advancing understanding of a specific issue. While the statement from The Catholic Common Ground Project particularly addresses the current state of the Catholic Church in the United States, its recognition of polarization in the Church is no less relevant for the situation of the Catholic Church as a whole in the very early days of the twenty-first century. In one way this is the case because the Church is understood principally in terms of the relations between local churches and the universal Church of Rome. Moreover, often people characterize a statement coming from either a local episcopal conference or the Pope or his representative as liberal or conservative merely because of its author. The same has been true with regard to well-developed and thoroughly researched positions of theologians that are often written not so much from one side or another of a disputed issue, but rather with intellectual acumen hopeful of genuinely contributing to the life of the Church in the world. In order to avoid making theological judgments purely based on ideological fixations and/or rooted in ecclesiastical politics, a guiding principle on every page of the dissertation is the acknowledgment, in Bemardin\u27s words, that the hermeneutic of suspicion must be balanced with a hermeneutic oflove and retrieval..
DLG2 impairs dsDNA break repair and maintains genome integrity in neuroblastoma
No full textBackground In primary neuroblastoma, deletions on chromosome 11q are known to result in an increase in the total number of chromosomal breaks. The DNA double-strand break repair pathways mediated by NHEJ are often upregulated in cancer. DLG2, a candidate tumor suppressor gene on chromosome 11q, has previously been implicated in DNA repair. Methods We evaluated an association between gene expression and neuroblastoma patient outcome, risk categorization, and 11q status using publicly available microarray data from independent neuroblastoma patient datasets. Functional studies were conducted using comet assay and H2AX phosphorylation in neuroblastoma cell lines and in the fruit fly with UVC-induced DNA breaks. Results We show that the NHEJ genes PARP1 and FEN1 are over expressed in neuroblastoma and restoration of DLG2 impairs their gene and protein expression. When exposed to UVC radiation, cells with DLG2 over expression show less DNA fragmentation and induce apoptosis in a p53 S46 dependent manner. We could also confirm that DLG2 over expression results in CHK1 phosphorylation consistent with previous reports of G2/M maintenance. Conclusions Taken together, we show that DLG2 over expression increases p53 mediated apoptosis in response to etoposide and UVC mediated genotoxicity and reduced DNA replication machinery.CC BY 4.0Corresponding author: E-mail address: [email protected] (S.

Relational comparisons: the assembling of Cleveland’s waterfront plan
No full textThis paper uses the ongoing attempts to redevelop the Cleveland waterfront to reveal the relational comparative geographies that are present in a number of contemporary urban revalorization strategies. It draws on archival papers, semi-structured interviews, and the local grey literature to make three contributions to the existing urban-global studies literature. First, the paper argues that many contemporary waterfront and other similar redevelopment schemes are inherently comparative, with a significant amount of seemingly territorial politics and urban policy making characterized by actors’ engagements with places elsewhere. Second, it shows that the framing of urban policy through relational comparisons is an established practice in many cities and that current redevelopment plans should be understood as informed by previous rounds of relational and territorial policy making. Third, it points to the importance of consultants in the current era – as examples of actors of transference – in shaping not only redevelopment plans but also the framing of the city in relation to other cities
Unconditional stability of difference formulas
No full textsummary:The paper concerns the solution of partial differential equations of evolution type by the finite difference method. The author discusses the general assumptions on the original equation as well as its discretization, which guarantee that the difference scheme is unconditionally stable, i.e. stable without any stability condition for the time-step. A new notion of the -acceptability of the integration formula is introduced and examples of such formulas are given. The results can be applied to ordinary differential equations as well
Increased healthcare utilization costs following initiation of insulin treatment in type 2 diabetes: A long-term follow-up in clinical practice
No full textAbstractAimsTo compare long-term changes in healthcare utilization and costs for type 2 diabetes patients before and after insulin initiation, as well as healthcare costs after insulin versus non-insulin anti-diabetic (NIAD) initiation.MethodsPatients newly initiated on insulin (n=2823) were identified in primary health care records from 84 Swedish primary care centers, between 1999 to 2009. First, healthcare costs per patient were evaluated for primary care, hospitalizations and secondary outpatient care, before and up to seven years after insulin initiation. Second, patients prescribed insulin in second line were matched to patients prescribed NIAD in second line, and the healthcare costs of the matched groups were compared.ResultsThe total mean annual healthcare cost increased from €1656 per patient 2 years before insulin initiation to €3814 seven years after insulin initiation. The total cumulative mean healthcare cost per patient at year 5 after second-line treatment was €13,823 in the insulin group compared to €9989 in the NIAD group.ConclusionsInitiation of insulin in type 2 diabetes patients was followed by increased healthcare costs. The increases in costs were larger than those seen in a matched patient population initiated on NIAD treatment in second-line
Optical polarimetry studies of Seyfert galaxies
No full textOptical imaging polarimetry has been performed on seven nearby Seyfert galaxies, three with face-on and four with edge-on host galaxies of various morphological classifications. Observations in V, R, B and H(_a) wavebands are presented as maps of total intensity and of polarized intensity, overlaid with polarization vectors. Independent determinations of the interstellar polarization (ISP) contribution from our own galaxy are made where possible, and are used to produce ISP corrected maps. The polarization patterns seen in the maps show evidence of either dichroic extinction, which indicates the presence of non-spherical dust grains in large-scale galactic magnetic fields, or scattering, which is due to the illumination of regions of dust grains or electrons. The polarization features, which are observed at the different wavebands, are then compared to recent models of polarization in external galaxies. Estimates of the intrinsic Seyfert nuclear polarization are made where possible by correcting for ISP and for an approximation of the dilution due to the host galaxy flux by using values from previous studies. Both the measured and the corrected nuclear polarizations are compared with previously published values, and are discussed in the context of the standard models of Seyfert galaxies. Most of the observed galaxies show evidence of polarization, both from the host galaxy and from the intrinsic Seyfert nucleus. In particular, distinct polarization features: bands of polarization consistent with extended dusty disks aligned with the dusty tori proposed in Seyferts, and regions of polarization corresponding to scattering of the nuclear continuum along the biconical extended Seyfert emission-line regions, have been identified in several of the observed galaxies
