The Influence of Peritectic Reaction/Transformation on Crack Susceptibility in the Continuous Casting of Steels
Authors: Saleem Saud , Vynnycky Michael , Fredriksson Hasse 
Published: February 2017

Abstract
The work presented here examines the surface cracks that can form during the continuous casting of near peritectic steels due to the volume changes during the peritectic reaction/transformation. The investigated samples were collected during plant trials from two different steel grades. The role and mode of the peritectic reaction/transformation are found to depend on the composition of the alloy, resulting in different types of surface cracks. The effect of the local variation in the cooling rate on the formation of the different types of cracks present in each steel grade, which can be due, for example, to the formation of oscillation marks, is demonstrated. The enhanced severity of the surface and internal oxidation, both of which depend on the alloy composition and consequent peritectic reaction, is highlighted. Experimental and theoretical studies show that different types of surface cracks can occur in peritectic steels depending upon the alloy composition and cooling rate, both of which define the fraction of the remaining liquid upon completion of the peritectic reaction/transformation.
Rheology of the Sponge Phase of the SDS–Hexanol–Brine System

Published: February 2017

AbstractWe have studied the rheological properties of the sponge phases (or L3) of the sodium dodecyl sulfate (SDS)–hexanol–brine (NaCl 20 g/l) system at different bilayer volume fractions. The most concentrated samples display a Newtonian behavior even at high shear rates, while the more diluted ones depart from it, probably due to a transition from the sponge to a lamellar structure. Two linear variation zones were observed when the viscosity was measured as a function of bilayer volume fraction. The effect of temperature on the rheology of a sample with bilayer volume fraction of 0.024 is discussed, and also how the addition to the system of polyethylene glycol, a water‐soluble polymer, affects this transition.
Novel Noninvasive Nuclear Medicine Imaging Techniques for Cardiac Inflammation
Authors: Kircher Malte , Lapa Constantin 
Published: February 2017

Abstract

Purpose of Review
Inflammation is a key player in a wide range of cardiovascular and myocardial diseases. Given the numerous implications of inflammatory processes in disease initiation and progression, functional imaging modalities including positron emission tomography (PET) represent valuable diagnostic, prognostic, and monitoring tools in patient management. Since increased glucose metabolism is a hallmark of inflammation, PET using the radiolabeled glucose analog [18F]-2-deoxy-2-fluoro-d-glucose (FDG) is the mainstay diagnostic test for nuclear imaging of (cardiac) inflammation. Recently, new approaches using more specific tracers to overcome the limited specificity of FDG have emerged.

Recent Findings
PET imaging has proven its value in a number of inflammatory conditions of the heart including myocarditis, endocarditis, sarcoidosis, or reactive changes after myocardial infarction. In infection-related endocarditis, FDG-PET and white blood cell scintigraphy have been implemented in current guidelines. FDG-PET is considered as nuclear medical gold standard in myocarditis, pericarditis, or sarcoidosis. Novel strategies, including targeting of somatostatin receptors or C-X-C motif chemokine receptor CXCR4, have shown promising results in first studies.

Summary
Nuclear medicine techniques offer valuable information in the assessment of myocardial inflammation. Given the possibility to directly visualize inflammatory activity, they represent useful tools for diagnosis, risk stratification, and therapy monitoring.
Discrete Barker Frailty and Warped Mortality Dynamics at Older Ages
Authors: Palloni Alberto , Beltrán-Sánchez Hiram 
Published: February 2017

Abstract
We develop a discrete variant of a general model for adult mortality influenced by the delayed impact of early conditions on adult health and mortality. The discrete variant of the model builds on an intuitively appealing interpretation of conditions that induce delayed effects and is an extension of the discrete form of the standard frailty model with distinct implications. We show that introducing delayed effects is equivalent to perturbing adult mortality patterns with a particular class of time-/age-varying frailty. We emphasize two main results. First, populations with delayed effects could experience unchanging or increasing adult mortality even when background mortality has been declining for long periods of time. Although this phenomenon also occurs in a regime with standard frailty, the distortions can be more severe under a regime with Barker frailty. As a consequence, conventional interpretations of the observed rates of adult mortality decline in societies that experience Barker frailty may be inappropriate. Second, the observed rate of senescence (slope of adult mortality rates) in populations with delayed effects could increase, decrease, or remain steady over time and across adult ages even though the rate of senescence of the background age pattern of mortality is time- and age-invariant. This second result implies that standard interpretations of empirical estimates of the slope of adult mortality rates in populations with delayed effects may be misleading because they can reflect mechanisms other than those inducing senescence as conventionally understood in the literature.
Tertiary center experience with primary endoscopic laryngoplasty in pediatric acquired subglottic stenosis and literature review
Authors: Alshammari Jaber , Alkhunaizi Arwa A. , Arafat Abdullah S. 
Published: February 2017

Background and objectives:
To share our experience with primary endoscopic laryngoplasty in pediatric acquired subglottic stenosis and critically review the previously published studies.

Setting:
Tertiary Referral Centers, King Abdulaziz Medical City, Riyadh, Saudi Arabia.

Patients and methods:
A retrospective case series study was conducted, where the case notes of all pediatric patients who underwent endoscopic management as a primary surgical intervention for acquired subglottic stenosis (SGS) from 2004 to 2014 were reviewed. All patients who underwent surgical correction with primary open laryngoplasty for congenital subglottic stenosis had been excluded.

Results:
A total of 60 patients with a workable diagnosis of subglottic stenosis were reviewed. Forty-five patients were included in the study and 15 patients were excluded because they underwent open laryngoplasty as a primary treatment modality for congenital subglottic stenosis. The majority of the patients were males 29 (64%), with 16 (36%) females. The main presentation was stridor and intercostal recession. Thirty-nine (86%) patients had subglottic stenosis due to prolonged intubation; 5 (11%) patients were idiopathic and one patient (3%) had inflammatory reasons. The site of stenosis was isolated SGS in 41 while 4 patients had glottic-subglottic stenosis (GSGS). In terms of the grade of stenosis: 13 patients had grade I; 23 had grade II and 9 had grade III. The character of stenosis was soft except in 5 patients with hard (mature) scar. The number of dilatation procedures ranged from 1 to 6 with a mean of 2. The endoscopic management was considered to be successful when the patient is completely asymptomatic after the follow up period of one year. No major complications were recorded among the patients. Thirty-seven (82.3%) patients had a benign course post endoscopic intervention without complications and 8 (17.7%) underwent a secondary open surgical management due to re-stenosis (P value < 0.01).

Conclusion:
Our study showed that primary endoscopic management was successful in 82.3% of cases of acquired subglottic stenosis including those with high grade stenosis and long segment of more than 12 mm in terms of the craniocaudal length. CO2 laser was an important tool to convert mature hard stenotic segment into a soft one. The latter yielded to the lateral pressure created by balloon dilatation better.
FREEDOM OF CONSCIENCE AS RELIGIOUS AND MORAL FREEDOM
Authors: Perry Michael J. 
Published: February 2017

AbstractIn another essay being published contemporaneously with this one, I have explained that as the concept “human right” is understood both in the Universal Declaration of Human Rights and in all the various international human rights treaties that have followed in the Universal Declaration's wake, a right is a human right if the rationale for establishing and protecting the right—for example, as a treaty-based right—is, in part, that conduct that violates the right violates the imperative, articulated in Article 1 of the Universal Declaration, to “act towards all human beings in a spirit of brotherhood.” Each of the human rights articulated in the Universal Declaration and/or in one or more international human rights treaties—for example, the right, articulated in Article 5 of the Universal Declaration and elsewhere, not to be subjected to “cruel, inhuman or degrading treatment or punishment”—is a specification of what, in conjunction with other considerations, the imperative—which functions in the morality of human rights as the normative ground of human rights—is thought to forbid (or to require). A particular specification is controversial if and to the extent the supporting claim—a claim to the effect that the “act towards all human beings in a spirit of brotherhood” imperative forbids (or requires)X—is controversial. My aim in this essay is to elaborate and defend a particular specification: the right, internationally recognized as a human right, to freedom of conscience—to freedom, that is, to live one's life in accord with the deliverances of one's conscience.
HAPPINESS AND THE RESTLESS HEART: AN AUGUSTINIAN CONFESSION
Authors: Johnson Luke Timothy 
Published: February 2017

AbstractSaint Augustine opens his Confessions with the words “Great art thou, O Lord, and greatly to be praised; great is thy power, and of thy wisdom there is no number. . . . this tiny part of all that Thou hast created desires to praise Thee. Thou dost so excite him that to praise Thee is his joy. For Thou hast made us for Thyself and our hearts are restless until they rest in Thee.” The author discovered these words, in the translation of Frank Sheed (New York: Sheed & Ward, 1943), at a young age, and the concluding line in particular, “For Thou hast made us for Thyself and our hearts are restless until they rest in Thee,” has occasioned continual return and reflection. In this article, the author investigates the meaning of this line in its context, following the phrase “to praise Thee is his joy.” Adopting a generous construal of his own experience with the text, the author examines some of the ways in which a person who wishes to be a Christian thinks about the elusive yet all-important dimension of human existence called happiness or joy.
APPLYING THE LESSONS: IDEALS VERSUS REALITIES OF HAPPINESS FROM MEDIEVAL ISLAM TO THE “FOUNDING FATHERS”
Authors: Cornell Vincent J. 
Published: February 2017

AbstractThe idea of happiness and its pursuit have been taken up by thinkers in many times and places. This article examines the role of happiness as a concept and goal in medieval Islamic thought and, especially, in the work of Abū Ḥāmid Muḥammad al-Ghazālī and Abū Naṣr al-Fārābī. In examining Ghazālī's and Fārābī's perspectives on happiness, the article looks at the influence of Plato and Aristotle on these medieval Islamic thinkers and puts Islamic thought on happiness in conversation with the views of the American founders.
Effects of almond consumption on the post-lunch dip and long-term cognitive function in energy-restricted overweight and obese adults
Authors: Dhillon Jaapna , Tan Sze-Yen , Mattes Richard D. 
Published: February 2017

AbstractThe post-lunch dip in cognition is a well-established phenomenon of decreased alertness, memory and vigilance after lunch consumption. Lunch composition reportedly influences the post-lunch dip. Moreover, dieting is associated with cognitive function impairments. The negative effects of dieting have been reversed with nut-supplemented diets. The aims of this study were to (1) evaluate the acute effect of an almond-enriched high-fat lunch or high-carbohydrate lunch on the post-lunch decline in cognitive function, and (2) evaluate the effects of chronic almond consumption as part of an energy-restricted diet on the memory and attention domains of cognitive function. In total, eighty-six overweight and obese adults were randomised to consume either an almond-enriched diet (AED) or a nut-free control diet (NFD) over a 12-week weight loss intervention. Participants were also randomised to receive either an almond-enriched high-fat lunch (A-HFL) (>55 % energy from fat, almonds contributing 70–75 % energy) or a high-carbohydrate lunch (HCL) (>85 % energy from carbohydrates) at the beginning and end of the weight loss intervention. Memory and attention performance indices decreased after lunch consumption (P<0·001). The A-HFL group ameliorated the decline in memory scores by 57·7 % compared with the HCL group (P=0·004). Both lunch groups had similar declines in attention. Moreover, memory and attention performance indices increased after the 12-week intervention period (P<0·05) with no difference between the AED and NFD groups. In conclusion, almond consumption at a midday meal can reduce the post-lunch dip in memory. However, long-term almond consumption may not further improve cognitive function outcomes in a weight loss intervention.
Robustness of plant–insect herbivore interaction networks to climate change in a fragmented temperate forest landscape

Published: February 2017

AbstractForest fragmentation and climate change are among the most severe and pervasive forms of human impact. Yet, their combined effects on plant–insect herbivore interaction networks, essential components of forest ecosystems with respect to biodiversity and functioning, are still poorly investigated, particularly in temperate forests. We addressed this issue by analysing plant-insect herbivore networks (PIHNs) from understories of three managed beech forest habitats: small forest fragments (2.2–145 ha), forest edges and forest interior areas within three continuous control forests (1050–5600 ha) in an old hyper-fragmented forest landscape in SW Germany. We assessed the impact of forest fragmentation, particularly edge effects, on PIHNs and the resulting differences in robustness against climate change by habitat-wise comparison of network topology and biologically realistic extinction cascades of networks following scores of vulnerability to climate change for the food plant species involved. Both the topological network metrics (complexity, nestedness, trophic niche redundancy) and robustness to climate change strongly increased in forest edges and fragments as opposed to the managed forest interior. The nature of the changes indicates that human impacts modify network structure mainly via host plant availability to insect herbivores. Improved robustness of PIHNs in forest edges/small fragments to climate-driven extinction cascades was attributable to an overall higher thermotolerance across plant communities, along with positive effects of network structure. The impoverishment of PIHNs in managed forest interiors and the suggested loss of insect diversity from climate-induced co-extinction highlight the need for further research efforts focusing on adequate silvicultural and conservation approaches.
What does the Southern Brazilian Coastal Plain tell about its diversity? Syrphidae (Diptera) as a model

Published: February 2017

AbstractThe natural areas of the Coastal Plain of Rio Grande do Sul (CPRS) have suffered fragmentation due to anthropic action. The faunal surveys offer a low-cost method to quickly evaluate environmental alterations, and Syrphidae flies are often used as models in this kind of study. We aimed to ascertain the diversity of Syrphidae in the South region of Brazil by estimating its species’ richness, and to use this data to identify new areas for conservation. In this survey Malaise traps were installed for 8 days in the CPRS, which was divided into five regions. Each region was subdivided into seven collecting areas and each of those areas received four traps, totaling 140 traps. A total of 456 Syrphidae individuals from 18 genera and 49 species were collected. In Region 1, there were nine exclusive species; in Region 2, there were three; in Region 3, there were 13, ten of which came from Estação Ecológica do Taim (ESEC Taim). In the Individual-based rarefaction analysis, Region 1 possessed the largest number of expected species out of the regions in the CPRS; we found 97% of these species. This insect collection effort, as one of the first in the CPRS, has broadened the known geographic distributions of 11 species of Syrphidae, and also indicated areas to be conserved. Additionally, it gave support for expanding ESEC Taim and creating new areas of conservation in Region 1, in Arroio Pelotas and Arroio Corrientes.

AbstractA range of endemic and protected vertebrate species from Madagascar are threatened by the demand for bushmeat. We report on the number of discarded carapaces from illegally killed Critically Endangered radiated tortoisesAstrochelys radiatain an urban centre in south-west Madagascar. Through covert monitoring of public rubbish dumps we observed 1,913 carapaces during July 2010–January 2014. There was notable spatial and temporal variation, with some evidence of peaks in carapace dumping during May–June and October–December. A single rubbish dump near the artisanal fishery landing beaches accounted for 93% of the observed carapaces.

Published: February 2017

SUMMARYTrypanosoma equiperdumpossesses a dense coat of a variant surface glycoprotein (VSG) that is used to evade the host immune response by a process known as antigenic variation. Soluble and membrane forms of the predominant VSG from the VenezuelanT. equiperdumTeAp-N/D1 strain (sVSG and mVSG, respectively) were purified to homogeneity; and antibodies against sVSG and mVSG were raised, isolated, and employed to produce anti-idiotypic antibodies that structurally mimic the VSG surface. Prospective VSG-binding partners were initially detected by far-Western blots, and then by immunoblots using the generated anti-idiotypic antibodies. Polypeptides of ~80 and 55 kDa were isolated when anti-idiotypic antibodies–Sepharose affinity matrixes were used as baits. Mass spectrometry sequencing yielded hits with various proteins fromTrypanosoma bruceisuch as heat-shock protein 70, tryparedoxin peroxidase, VSG variants, expression site associated gene product 6, and two hypothetical proteins. In addition, a possible interaction with a protein homologous to the glutamic acid/alanine-rich protein fromTrypanosoma congolensewas also found. These results indicate that the corresponding orthologous gene products are candidates for VSG-interacting proteins inT. equiperdum.
A Year of One's Own: Dating the Praetorship of Marcus Crassus
Authors: Stone Martin 
Published: February 2017

AbstractIt is curious that, although a wholeLifeof Plutarch is devoted to Marcus Crassus, so little is known as to the facts and dates of hiscursus honorum.His praetorship is a fact, but of uncertain date. Plutarch is often interpreted as associating it with his special command against Spartacus in 72; Appian can be read as placing it in 71. A virtual consensus of scholars follows Broughton in favouring 73. It is contended here that Crassus' destined year was 75, when he turned 40. That it was his actual year is supported by his nobility, ambition and talent: one of eight places should have been his. No province is attested or likely. But the limited availability of praetorian provinces in these years and Crassus' known interest in special commands make this unproblematic.The early dating proposed makes sense of the absence of an aedileship. It creates, however, an expected consular year of 72. The blocking of this is associated with the discourse of rivalry between Crassus and Pompey: the very odd trial forincestumwith a Vestal Virgin finds explanation in this context. The article aspires to shine a light on the post-civil war period in which Crassus, no less than Pompey, is both player and exemplar.
The Jews in Rome during the Flavian Period
Authors: McLaren James S. 
Published: February 2017

AbstractDuring the late republic and early principate the Jews who called Rome their home occasionally found themselves in the public gaze. Some of their customs and aspects of their ways of life also attracted occasional comment, often for their apparently strange and foreign manner. At no stage, however, during this period did they feature prominently in the public sphere of life in Rome. The aftermath of the war of 66-70 CE brought about an abrupt change in circumstances for the Jews living in Rome. Apart from the immediate visual celebration of the triumph, there followed a number of substantial monumental and numismatic commemorations of the Roman victory. In this article the purpose and function of those commemorations and the possible consequences for the Jews who lived in Rome are examined. In particular, the impact of the public profiling of the war on Jewish identity and of how the writings of Josephus are to be read in this setting is explored. Rather than regard Josephus as a supporter of the Flavian rulers, writing an account of the war that encouraged fellow Jews to collaborate with Rome, it is argued that he was offering Jews in Rome a counter-narrative to the way the war was being publicly commemorated.
Representing the Battle of Zama to Create an Iconic Event
Authors: Billot Frances 
Published: February 2017

AbstractThis article compares the use of certain literary, structural and historical features by Polybius, Livy and Silius Italicus in their representations of the battle of Zama in 202 BC between the Romans and Carthaginians. It is argued that through their application of these features they present the battle as an iconic event and position it as a grand finale to the Second Punic War. The comparisons highlight some of the literary constructs in Polybius’Historiesand illustrate how some later authors adapt and possibly respond to Polybius’ presentation.Similarities in presentation to emphasise the importance of the battle do not necessarily mean that the authors convey the same message over the long term effects of its outcome. For example, where Polybius’ special treatment of the battle of Zama, Hannibal and Scipio reflects his belief in the pivotal role the Roman victory played in changing the balance of power across the ancient Mediterranean world (15.9.2, 10.2), Silius Italicus’ special treatment may also be read as presenting the outcome of the battle in terms of causing a shift in power balance, in this case within the city of Rome, and leading to the development of the principate and the one-man rule of imperial Rome (17.653-4, 3.261-4).
