ZL-130TCII Fracture Markers Solution for Full-Scale Fatigue TestIn the context of PZL-130TC-II full-scale fatigue test, several strategies of fatigue loadings that create fracture surface markings were considered. One block of spectrum is made of 200 flights. By reordering those flights, a block which should create a fracture marker, was developed. It was very important that reordering the load spectrum or adding overloads or underloads did not change spectrum severity. Pilot tests of aluminium alloys specimens were carried out to finalise appropriate marker intervals before commencing full-scale tests. The experiment was conducted with the MTS machine with 810.23 system. The results and conclusions are presented within this paper.

Investigation into Fatigue Behaviour of Metal-Composite Glue Connection
The paper presents the results of experimental investigations into fatigue properties of metal and CFRP-composite glued joints. The object of investigation was adhesive joints between metal sheets made from iron alloy 30HGS (popular steel in the Polish aviation industry) and CFRP orthogonal reinforced sheets made from 10 layers of SIGRATEX CE3208 pre-preg. The main adhesive was the WK-3 glue (applied in the form of 0.2 mm thin foil) while the DP-490 - liquid epoxy glue was used as technological aid for specimen manufacturing. Two kinds of specimens were prepared and tested: single-lap joints and double-lap joints. The paper presents S-N curves for both kinds of those specimens. Besides fatigue life of the glued joints, the interest was focused on the NDT tests regarding damage propagation inside the glue-connection. The paper presents several C-scans made at different stages of fatigue testing. It has been found that the damage occurs almost equally in the whole volume of the glue layer (contrary to the expectation following from the physical model of the glue-connection internal loading). The results of experiments regarding thermal effect of cyclic loading of the glued joints are also described. It has been found that this effect could be used as an important parameter for diagnostics purposes of the glued joints.

Experimental and Numerical Crack Initiation Analysis of the Compressor Blades Working in Resonance ConditionsThis paper presents the results of a complex experimental and numerical crack initiation analysis of the helicopter turbo-engine compressor blades subjected to vibrations. A nonlinear finite element method was utilized to determine the stress state of the blade during the first mode of transverse vibration. In this analysis, the numerical models without defects as well as those with V-notches were defined. The quality of the numerical solution was checked by the convergence analysis. The obtained results were next used as an input data into crack initiation (ε-N) analyses performed for the load time history equivalent to one cycle of the transverse vibration. In the fatigue analysis, the different methods such as: Neuber elastic-plastic strain correction, linear damage summation and Palmgreen-Miner rule were utilized. As a result of ε-N analysis, the number of load cycles to the first fatigue crack appearing in the compressor blades was obtained. Moreover, the influence of the blade vibration amplitude on the number of cycles to the crack initiation was analyzed. Values of the fatigue properties of the blade material were calculated using the Baumel-Seeger and Muralidharan methods. The influence of both the notch radius and values of the UTS of the blade material on the fatigue behavior of the structure was also considered. In the last part of the work, the finite element results were compared with the results of experimental vibration HCF tests performed for the compressor blades.

Published: August 2011

BackgroundCerebral autoregulation can be impaired after ischemic stroke, with potential adverse effects on cerebral blood flow during early rehabilitation.ObjectiveThe objective of this study was to assess changes in cerebral blood flow velocity with orthostatic variation at 24 hours after stroke.DesignThis investigation was an observational study comparing mean flow velocities (MFVs) at 30, 15, and 0 degrees of elevation of the head of the bed (HOB).MethodsEight participants underwent bilateral middle cerebral artery (MCA) transcranial Doppler monitoring during orthostatic variation at 24 hours after ischemic stroke. Computed tomography angiography separated participants into recanalized (artery completely reopened) and incompletely recanalized groups. Friedman tests were used to determine MFVs at the various HOB angles. Mann-Whitney U tests were used to compare the change in MFV (from 30° to 0°) between groups and between hemispheres within groups.ResultsFor stroke-affected MCAs in the incompletely recanalized group, MFVs differed at the various HOB angles (30°: median MFV=51.5 cm/s, interquartile range [IQR]=33.0 to 103.8; 15°: median MFV=55.5 cm/s, IQR=34.0 to 117.5; 0°: median MFV=85.0 cm/s, IQR=58.8 to 127.0); there were no significant differences for other MCAs. For stroke-affected MCAs in the incompletely recanalized group, MFVs increased with a change in the HOB angle from 30 degrees to 0 degrees by a median of 26.0 cm/s (IQR=21.3 to 35.3); there were no significant changes in the recanalized group (−3.5 cm/s, IQR=−12.3 to 0.8). The changes in MFV with a change in the HOB angle from 30 degrees to 0 degrees differed between hemispheres in the incompletely recanalized group but not in the recanalized group.LimitationsGeneralizability was limited by sample size.ConclusionsThe incompletely recanalized group showed changes in MFVs at various HOB angles, suggesting that cerebral blood flow in this group may be sensitive to orthostatic variation, whereas the recanalized group maintained stable blood flow velocities.

Published: August 2011

Objectives: The aim of this study was to establish the predictive value of an ICD-10 diagnosis of depressive disorder or dysthymia (depressive patients) among 70 years + frail rural community living patients by measuring morbidity, mortality and use of health services. Identical measures were studied over time in general elderly populations. Methods: Outcome measures: morbidity, mortality and use of health services were registered over 13 years in: (i) a clinical cohort of frail community-living depressive patients (n = 38), a frail control group (n = 116) and non-frail elderly people (n = 575), all living in the same municipality, and (ii) register-based samples of general rural (n = 4 115) and capital living (n = 54 977) elderly populations. The outcome measures were compared using data from Danish national health registers. Results: Every one of the clinical cohort of depressive patients had died at the end of the study. Compared with both the frail control group and the non-frail elderly people, the depressive patients had significantly more psychiatric hospital days, outpatient home visits, antidepressant use, antipsychotic use, GP service use and more psychiatric diagnoses with higher morbidity. However, greater use of somatic hospital services or more somatic diagnoses among the depressive elderly patients were not observed. The general elderly population living in the capital had, compared with rural equals, significantly more somatic and psychiatric diagnoses, larger use of somatic hospital services, psychiatric hospital days, antipsychotics and anxiolytics, but less use of antidepressants, psychiatric outpatient home visits and GP services. Conclusions: An ICD-10 diagnosis of depressive disorder or dysthymia predicted increased use of psychiatric services, more psychiatric diagnoses and increased mortality, indicating poor late-life psychiatric outcome. Contrasting with other studies, depression did not predict increased use of somatic hospital services or more somatic diagnoses. The differences in health care status and use between elderly living in the capital and in rural areas elderly are novel findings.

Published: August 2011

Objective: The aim of this study was to assess 12 month outcomes of Australian combat veterans with post-traumatic stress disorder (PTSD) who participated in a 6 week group-based CBT programme at the Toowong Private Hospital. The study population included 496 consecutive admissions to the programme between 1999 and 2008. Method: Self-report measures of PTSD, depression, anxiety, anger, alcohol use, relationship satisfaction and quality of life parameters were collected at intake and 3, 6 and 12 months post intake. Results: Statistically significant and sustained improvements were noted in 12 month outcome measures for PTSD, depression, anxiety, alcohol use, anger, and quality of life. PTSD symptom reduction occurred consistently each year for 9 years and exhibited an aggregated effect size of 0.68. Conclusions: This naturalistic research demonstrates that treatment administered under clinical conditions produces equivocal magnitudes of positive change in terms of PTSD symptoms when compared with existing efficacy data in individual and group treatments. Further, these symptomatic gains are sustainable and consistently reproducible. The benefits noted from group therapy were seen as independent of whether or not individual treatment was in place.
Becoming Christian: Relations between Faith and Sacrament in Christian Initiation
Authors: Arjakovsky Antoine , Fortin Jean-Pierre 
Published: August 2011

Abstract: This article attempts to account for the almost complete lack of official mutual recognition expressed by the Christian churches, despite the unprecedented level of convergence between them. Analysis of the important body of literature issued from the ecumenical dialogue that has taken place over the last fifty years leads the author to several conclusions: Christian salvation can be understood, without contradiction, as both instantaneous (effected by God at the moment of baptism) and progressive (via the continual renewal of the believer's life in the sacraments of Eucharist and penance). The Church can be conceived as a multilevel entity not composed of confessions but of three fundamental and complementary types of believers (zealots, proselytes, and spirituals). On this basis, the author argues for the necessary coexistence, within the Church, of difference and complementarity. For Church unity to be lasting and faithful to Christian life, it ought to be found in and actualized as integrated diversity.
From Žižek's Monstrous Politics to the Political Theology of Kierkegaard's Housing Project
Authors: Zlomislić Marko 
Published: August 2011

Abstract: Slavoj Žižek's leading question is how we are to reformulate a leftist anti-capitalist project in an era of global capitalism. In attempting to answer this question, Žižek often uses Kierkegaard's insights to add weight to his analysis of the problems associated with our social and political reality. Yet when one reads Žižek's work on Kierkegaard one is struck by the sheer number of inconsistencies that are generated. Žižek considers Kierkegaard from the point of view of the political in such a way that he avoids the religious, but Kierkegaard is clear that if a proper politics is to exist, it must be grounded in religious selfhood. The single individual, as Kierkegaard makes clear in Two Ages, is “an essentially human person in the religious sense.” Kierkegaard's views are directed by a religious notion of selfhood. Politics without this source is a form of despair. By failing to see ourselves as religious beings, we are in despair. This despair cannot be the basis from which to transform the coordinates of our current position. Kierkegaard's philosophy provides us with a radical opening from which to re-think political theology from the position of the single individual to come. The program that Žižek upholds is not adequate for the transformation of society or self because it does not have a religious understanding of the individual. As such, Žižek's position is grounded in despair, not love.
Beyond Christendom: New Maps
Authors: González Justo L. 
Published: August 2011

Abstract: The result of the great century of Protestant expansion, the nineteenth, has not been the expansion of Christendom, but rather its end. This has not meant a retreat on of Christianity, which is rapidly growing in what used to be the “mission field.” But it has resulted in a new state in which Christianity, beyond being merely universal, is rapidly becoming cath'holic in the original sense of being “according to the whole.” Just as the Church has learned to live with a cath'holic canon of Scripture that includes a wide variety of perspectives, it will now have to learn how to be a Church that includes a wide variety of perspectives. This variety challenges and enriches the manner in which we read the canonical texts of Christianity, as well as its theology and history. Finally, some examples from the field of Church history are given.
French Apocalyptic Messianism: Isaac La Peyrère and Political Biblical Criticism in the Seventeenth Century
Authors: Morrow Jeffrey L. 
Published: August 2011

Abstract: Isaac La Peyrère is one of the most important and yet little-known seventeenth-century intellectuals involved in developing modern biblical criticism. His work on the Bible resembles that of his later contemporaries Thomas Hobbes, Baruch Spinoza, and La Peyrère's friend Richard Simon, all of whom his writings may have influenced. Through his attempt to get behind the biblical texts and his use of comparative extra-biblical historical literature from across the globe, La Peyrère's methods attempted to mould biblical exegesis into historical criticism. His social and political context in seventeenth-century France during the reign of King Louis xiv provides an important glimpse into the historical background that shaped La Peyrère's thought and project. At its core, La Peyrère's work was not scholarship for its own sake, but was politically motivated. His exegesis entailed an elaborate theo-political messianic vision, which his historical method was an attempt to bolster. La Peyrère's biblical exegesis was in service of his French apocalyptic messianic vision, the heart of which supported the political designs of his employer, the Prince of Condé.
The Evasion of Ethics: Peter Paris Feels the Spirituals
Authors: Wariboko Nimi 
Published: August 2011

Abstract: This paper provides not only a systematic account of the theology and ethics of Peter Paris, but also a critical interpretation of his thought. It identifies racism as the major problem that has engaged his academic career and the theological-ethical methodology he has developed to understand and explain it. He is been able to do all this in ways that evade and challenge the American theological enterprise. The primary theme of Paris's work is evading epistemology-centred ethics, exposing racism and injustice, and accenting the transformation of the structures of domination and subordination in the light of an ethical ideal, which is usually the thwarting of evil or actualization of human potentialities. In doing this, he converts ethics into a positive science of social critique and cultural investigation of the social crises of the United States. The importance of this paper goes beyond interpreting Paris's thought, as it will be useful to scholars teaching ethics in general and African-American ethics in particular. Paris's evasion of ethics is rooted in the black religious tradition of ethical critique of American society in order to expose its moral limits and remind it of its blindnesses, as W.E.B. Du Bois informed us. The paper—in also locating the thought of Paris in the deep ethos that informed the spirituals—reveals another major dimension of African-American ethical scholarship. Most importantly, by carefully discussing the ethical methodology of Paris in particular, this paper clarifies that of African-American ethicists in general.
Politicizing Biology: Daniel Dennett's Breaking the Spell: Part II
Authors: Hynes Darren , Wills Bernard 
Published: August 2011

Abstract: In a previous paper we critiqued Daniel Dennett's evolutionary science of religion as expounded in his book Breaking the Spell. In the present paper we wish to follow up on this line of inquiry and discuss in more detail and depth the political and social implications of Dennett's work. The authors find that while Dennett's science of religion and the memetic theory of culture on which it rests are scarcely persuasive as science, they are an effective species of “bio-rhetoric” whose purpose is to defend the status of the sciences and the public supremacy of the “physical stance” on which Dennett thinks they rest. In the conclusion of the paper the authors suggest that Dennett's use of the rhetoric of naturalism and in particular the “science” of memetics has disturbing implications when understood in the context of the post-9/11 world.
Increasing treatment of ruptured cerebral aneurysms at high-volume centers in the United States
Authors: Leake Caleb B. , Brinjikji Waleed , Kallmes David F. , Cloft Harry J. 
Published: August 2011

Object
Evidence of better outcomes in patients with aneurysmal subarachnoid hemorrhage treated at higher-volume centers might be expected to result in more of these patients being referred to such centers. The authors evaluated the US National Inpatient Sample for the years 2001 to 2008 for trends in patient admissions for the treatment of ruptured aneurysms at high- and low-volume centers.

Methods
The authors determined the number of ruptured aneurysms treated with clipping or coiling annually at low-volume (≤ 20 patients/year) and high-volume (> 20 patients/year) centers and also counted the number of high- and low-volume centers performing each treatment. Hospitalizations for clipping or coiling ruptured aneurysms were identified by cross-matching International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) codes for the diagnosis of a ruptured aneurysm (ICD-9-CM 430) with procedure codes for clipping (ICD-9-CM 39.51) or coiling (ICD-9-CM 39.52, 39.79, or 39.72) cerebral aneurysms.

Results
In 2001, 31% (435 of 1392) of the patients who underwent clipping and 0% (0 of 122 patients) of those who underwent coiling did so at high-volume centers, whereas in 2008 these numbers increased to 62% (627 of 1016) and 68% (917 of 1351) of patients, respectively. For clipping procedures, the number of low-volume centers significantly declined from 177 in 2001 to 85 in 2008, whereas the number of high-volume centers remained constant at 13–15. For coiling procedures, the number of low-volume centers decreased from 62 in 2001 to 54 in 2008, whereas the number of high-volume centers substantially increased from 0 in 2001 to 16 in 2005 and remained constant thereafter.

Conclusions
The treatment of ruptured cerebral aneurysms increasingly occurs at high-volume centers in the US. This trend is favorable given that better outcomes are associated with the treatment of these lesions at high-volume centers.
Research productivity in neurosurgery: trends in globalization, scientific focus, and funding
Authors: Hauptman Jason S. , Chow Daniel S. , Martin Neil A. , Itagaki Michael W. 
Published: August 2011

Object
While research is important for the survival, growth, and expansion of neurosurgery, little work has been done to quantify the status and trends of neurosurgical publications. The purpose of this bibliometric study was to quantitatively analyze trends in neurosurgical publications, including changes in worldwide productivity, study methodology, subspecialty topic, and funding.

Methods
This was a retrospective bibliometric study using MEDLINE to record all publications between 1996 and 2009 by first authors affiliated with neurosurgical departments. Country of origin, MEDLINE-defined methodology, study topic, and funding sources (for US articles) were recorded. Linear regression was used to derive growth rates.

Results
Total articles numbered 53,425 during the study period, with leading global contributors including the US with 16,943 articles (31.7%) and Japan with 10,802 articles (20.2%). Countries demonstrating rapid growth in productivity included China (121.9 ± 9.98%/year, p < 0.001), South Korea (50.5 ± 4.7%/year, p < 0.001), India (19.4 ± 1.8%/year, p < 0.001), and Turkey (25.3 ± 2.8%/year, p < 0.001). While general research articles, case reports, and review articles have shown steady growth since 1996, clinical trials and randomized controlled trials have declined to 2004 levels. The greatest overall subspecialty growth was seen in spine surgery. Regarding funding, relative contribution of National Institutes of Health (NIH)–funded publications decreased from 30.2% (290 of 959) to 22.5% (356 of 1229) between 1996 and 2009.

Conclusions
Neurosurgical publications demonstrate continued increases in productivity as well as in global expansion, although US contributions remain dominant. Two challenges that the neurosurgical community is facing include the preponderance of case reports and review articles and the relative decline in NIH funding for US neurosurgical publications, as productivity has outpaced government financial support.
Closed Left Ideal Decompositions of U(G)
Authors: Zelenyuk Yevhen 
Published: August 2011

AbstractLet G be an infinite discrete group and let βG be the Stone-Čech compactification of G. We take the points of βG to be the ultrafilters on G, identifying the principal ultrafilters with the points of G. The set U(G) of uniform ultrafilters on G is a closed two-sided ideal of βG. For every p ∊ U(G), define Ip ⊆ βG by Ip = ∩ A∊p cl(GU(A)), whereU(A) = {p ∊ U(G) : A ∊ p}. We show that if |G| is a regular cardinal, then {Ip : p ∊ U(G)} is the finest decomposition of U(G) into closed left ideals of βG such that the corresponding quotient space of U(G) is Hausdorff.

AbstractTotal embedding distributions have been known for a few classes of graphs. Chen, Gross, and Rieper computed it for necklaces, close-end ladders and cobblestone paths. Kwak and Shim computed it for bouquets of circles and dipoles. In this paper, a splitting theorem is generalized and the embedding distributions of generalized fan graphs are obtained
