MULTIAXIAL STRESS TESTS FOR METAL SHEETS AND TUBES FOR ACCURATE MATERIAL MODELING AND FORMING SIMULATIONS
Authors: Kuwabara Toshihiko 
Published: April 2015

This paper is a review of the mechanical testing methods developed by the author's research group: multiaxial stress test methods using a cruciform test piece and a tubular test piece. The former is useful for small strain ranges under several percent while the latter is useful for larger strain ranges (from yielding to fracture). These test methods are useful to determine appropriate materials model for performing accurate metal forming simulations. Special attention is given to the measurement and modeling of the anisotropic plastic deformation behavior of sheet metals commonly used in industry and to the validation of the material models based on phenomenological yield functions for large plastic strain ranges. The effects of material models used in metal forming simulations on the improvement of the predictive accuracy for forming defects are also discussed.

Published: April 2015

The assessment of the residual lifetime of critical components of industrial plants requires the knowledge of mechanical properties prior to operation, respecting all technological operations realized throughout the manufacture of the component, and the knowledge of mechanical properties after actual time of operation (actual mechanical properties). The conventional mechanical tests require relatively large volume of testing material and extracting it from an operating component can impair its integrity. The need for evaluating the actual mechanical properties by direct testing method has led to development of innovative techniques based on miniaturized specimens. Among these, a technique called the Small Punch (SP) test has emerged as a promising candidate. It enables measurement of the realistic material properties at the critical locations in the component both prior and after long-term operation. Yield stress and tensile strength at ambient temperature are determined from empirical correlations between SP and standardized test results. In the present paper the empirical correlations obtained in two laboratories for determination of yield stress and tensile strength of low alloy steel of type 14MoV6-3 in as received state from the results of SP tests are compared and the differences obtained are discussed. The results obtained demonstrate the significance of loading system stiffness on the results of SP tests at laboratory temperature.

Published: April 2015

This article deals with the analysis and use of Mn ore fines in the production of ferroalloys. The paper focuses on the evaluation of Mn ores in terms of their chemical and phase composition. Mn ore fines are formed in the process of mining, transport and processing of Mn ores in factories. These small particles cannot be directly put into the furnace; they should be edit before they are used. The most appropriate treatment method of Mn ore fines is sintering. Laboratory experiments were done with Mn ore from Turkey, Bosnia and Herzegovina and Bulgaria. Analyses of the Mn ores were performed in order to determine their various properties, according to which conditions were adapted for laboratory experiments to produce the best quality Mn sinter. Chemical and phase composition and thermal analysis have been performed on the ores. The phase analysis showed that the ore from Turkey and Bulgaria are in the carbonate form and the ore from Bosnia and Herzegovina is in the oxide form. DTG analysis showed that, by the thermally heating the biggest weight loss happened in the Mn ore from Bulgaria. For the best quality ore can be considered the Mn ore from Turkey because it containsthe highest % of Mn, lowest content of SiO2 and the ore has the lowest % of P. The sizing of Mn ore fines was carried out in laboratory conditions on a laboratory sintering pan. Produced Mn sinters were subjected to analysis of their chemical and phase composition. Produced Mn sinters have higher content of Mntot compared to Mn ores. As a result of Mn ore sintering the form of majority compounds changed - silicates, carbonates and hydrates of manganese in the starting Mn ores were in the produced Mn sinters analysed majority compounds based on the higher oxides of Mn and Fe, which is in the process for production of Mn ferroalloys positive.

Correlation between some technological parameters and properties of composite material based on recycled tires and polymer binder
Authors: Plesuma Renate , Malers Laimonis 
Published: April 2015

AbstractThe present article is dedicated to the determination of a possible connection between the composition, specific properties of the composite material and molding pressure as an important technological parameter. Apparent density, Shore C hardness, compressive modulus of elasticity and compressive stress at 10% deformation was determined for composite material samples. Definite formation conditions – varying molding pressure conditions at ambient temperature and corresponding relative air humiditywere realized. The results obtained showed a significant effect of molding pressure on the apparent density, mechanical properties of composite material as well as on the compressive stress change at a cyclic mode of loading. Some general regularities were determined - mechanical properties of the composite material, as well as values of Shore C hardness increases with an increase of molding pressure.
“I Was Exhausted as a Woman”: The Slippage of Virtue and Gender in the Testament of Job
Authors: Pettit David 
Published: April 2015

Abstract
The Testament of Job is a Hellenistic reception of the biblical Book of Job written sometime between the first century BCE and first century CE. This paper is attentive to Hellenistic notions of the masculine ideal as one fused with notions of virtue, where gender corresponds to virtue more than to anatomy. Masculinity is a continuum on which one’s masculinity and virtuousness is subject to slippage. It is this dynamic that energizes and dramatizes the narrative of the Testament of Job: Job is engaged in a wrestling match to demonstrate his virtue, and to prevail over weakness and traits associated with femininity.

Published: April 2015

Background: Osteocytic sclerostin inhibits bone formation, and its expression is stimulated by tumor necrosis factor (TNF)‐α. This study investigates sclerostin and TNF‐α expression in rats with diabetes mellitus (DM) and periodontitis.Methods: Rats were divided into control (C), periodontitis (P), and DM + periodontitis (DP) groups. After induction of DM by streptozotocin, periodontitis was induced by ligature. At day 0 (control) and at days 3 and 20 after induction of periodontitis, alveolar bone, osteoclasts, osteoid area, and TNF‐α and sclerostin expression were evaluated.Results: The distance between the cemento‐enamel junction and the alveolar bone crest of the DP group was longer than that of the P group at day 20 after induction of periodontitis, but the number of osteoclasts was not different. Osteoid area decreased in both the P and DP groups by day 3, but whereas sustained osteoid suppression was observed in the DP group at day 20, osteoid formation was increased in the P group. The number of sclerostin‐positive osteocytes increased in both groups at day 3, but the increased number of sclerostin‐positive osteocytes was maintained only in the DP group through day 20. The number of TNF‐α–positive cells increased more in the DP group than in the P group.Conclusions: Enhanced alveolar bone loss, suppressed bone formation, and prevalent TNF‐α expression were characteristic of the DP group compared with the P group. Suppressed bone formation in the DP group was observed simultaneously with increased sclerostin and TNF‐α expression. These results suggest that upregulated osteocytic sclerostin expression in periodontitis accompanied by DM may play a role in suppressed bone formation.

Published: April 2015

ABSTRACT: Electrochemical degradation of rhodamine B (C28H31ClN2O3) over Ti/SnO2‐Sb anode was investigated in a rectangular cell. The degradation reaction follows pseudo‐first‐order kinetics. The degradation efficiency of rhodamine B attained >90.0% after 20 minutes of electrolysis at initial concentrations of 5 to 200 mg/L at a constant current density of 20 mA/cm2 with a 10 mmol/L Na2SO4 supporting electrolyte solution. Rhodamine B (50 mg/L) degradation and total organic carbon (TOC) removal ratio achieved 99.9 and 86.7%, respectively, at the optimal conditions after 30 minutes of electrolysis. The results showed that the energy efficiency of rhodamine B (50 mg/L) degradation at the optimal current densities from 2 to 30 mA/cm2 were 23.2 to 84.6 Wh/L, whereas the electrolysis time for 90% degradation of rhodamine B with Ti/SnO2‐Sb anode was 36.6 and 7.3 minutes, respectively. The electrochemical method can be an advisable option for the treatment of dyes such as rhodamine B in wastewater.
MicroRNAs are central to osteogenesis: a review with a focus on cardiovascular calcification
Authors: Coffey Sean , Jones Gregory T 
Published: April 2015

AbstractCardiovascular calcification, manifested by coronary artery calcification and aortic valve stenosis, is a widespread condition that is becoming more common with the aging of the general population. No disease-modifying therapies currently exist for any forms of cardiovascular calcification. A number of similarities exist between pathological calcification in cardiovascular tissue and physiological calcification in bone, termed osteogenesis. MicroRNAs are small noncoding RNAs that have been shown to have multiple effects throughout the cardiovascular system. In this review, we discuss the pre-clinical evidence supporting a role for microRNAs in osteogenesis, with a focus on cardiovascular calcification. The microRNAs with most evidence implicating them in the disease process are the miR-17~92 cluster, miR-23a/27a/24-2 family, miR-26a, miR-29b, the miR-30 family, miR-31, miR-125b, miR-133a, miR-143/145, miR-155, and miR-221/222. We also highlight the limitations of current evidence in this field, such as the lack of studies using high-throughput technologies.

Published: April 2015

Abstract
Phase equilibria in the Co–Fe–Ti ternary system were investigated by means of the equilibrated alloy method with X-ray powder diffraction and electron probe microanalysis. No ternary compounds were found. The experimental results indicated the existence of seven two-phase and one three-phase regions at 600°C, five two-phase and two three-phase regions at 800°C, and six two-phase and two three-phase regions at 950°C. The solubility of Co in TiFe2 was determined to be larger than 54 at.% at all investigated temperatures, and the solubilities of Fe in TiCo3 and Ti2Co showed an appreciable increase with increasing temperature. The three-phase equilibrium in the Ti-rich corner at 800°C was revealed to be ((β-Ti) + Ti(Fe, Co) + Ti2Co) rather than ((α-Ti) + Ti(Fe, Co) + Ti2Co) reported in previous investigations. Based on the experimental data obtained in the present work, three isothermal sections at 600, 800 and 950°C were established.
Muscle-Activation Onset Times With Shoes and Foot Orthoses in Participants With Chronic Ankle Instability
Authors: Dingenen Bart , Peeraer Louis , Deschamps Kevin , Fieuws Steffen , Janssens Luc , Staes Filip 
Published: April 2015

Context
Participants with chronic ankle instability (CAI) use an altered neuromuscular strategy to shift weight from double-legged to single-legged stance. Shoes and foot orthoses may influence these muscle-activation patterns.

Objective
To evaluate the influence of shoes and foot orthoses on onset times of lower extremity muscle activity in participants with CAI during the transition from double-legged to single-legged stance.

Design
Cross-sectional study.

Setting
Musculoskeletal laboratory.

Patients or Other Participants
A total of 15 people (9 men, 6 women; age = 21.8 ± 3.0 years, height = 177.7 ± 9.6 cm, mass = 72.0 ± 14.6 kg) who had CAI and wore foot orthoses were recruited.

Intervention(s)
A transition task from double-legged to single-legged stance was performed with eyes open and with eyes closed. Both limbs were tested in 4 experimental conditions: (1) barefoot (BF), (2) shoes only, (3) shoes with standard foot orthoses, and (4) shoes with custom foot orthoses (SCFO).

Main Outcome Measure(s)
The onset of activity of 9 lower extremity muscles was recorded using surface electromyography and a single force plate.

Results
Based on a full-factorial (condition, region, limb, vision) linear model for repeated measures, we found a condition effect (F3,91.8 = 9.39, P &lt; .001). Differences among experimental conditions did not depend on limb or vision condition. Based on a 2-way (condition, muscle) linear model within each region (ankle, knee, hip), earlier muscle-activation onset times were observed in the SCFO than in the BF condition for the peroneus longus (P &lt; .001), tibialis anterior (P = .003), vastus medialis obliquus (P = .04), and vastus lateralis (P = .005). Furthermore, the peroneus longus was activated earlier in the shoes-only (P = .02) and shoes-with-standard-foot-orthoses (P = .03) conditions than in the BF condition. No differences were observed for the hip muscles.

Conclusions
Earlier onset of muscle activity was most apparent in the SCFO condition for ankle and knee muscles but not for hip muscles during the transition from double-legged to single-legged stance. These findings might help clinicians understand how shoes and foot orthoses can influence neuromuscular control in participants with CAI.
On a Linear Refinement of the Prékopa-Leindler Inequality
Authors: Colesanti Andrea , Saorín Gómez Eugenia , Yepes Nicolás Jesύs 
Published: April 2015

AbstractIf f,g:ℝn→ ℝ≥0 are non-negative measurable functions, then the Prékopa–Leindler inequality asserts that the integral of the Asplund sum (provided that it is measurable) is greater than or equal to the 0-mean of the integrals of f and g. In this paper we prove that under the sole assumption that f and g have a common projection onto a hyperplane, the Prékopa–Leindler inequality admits a linear refinement. Moreover, the same inequality can be obtained when assuming that both projections (not necessarily equal as functions) have the same integral. An analogous approach may be also carried out for the so-called Borell-Brascamp-Lieb inequality.

Published: April 2015

AbstractThe Qpspaces of holomorphic functions on the disk, hyperbolic Riemann surfaces or complex unit ball have been studied deeply. Meanwhile, there are a lot of papers devoted to theclasses of meromorphic functions on the disk or hyperbolic Riemann surfaces. In this paper, we prove the nesting property (inclusion relations) ofclasses on hyperbolic Riemann surfaces. The same property for Qp spaces was also established systematically and precisely in earlier work by the authors of this paper.
Is a Marxist explanation of the current crisis possible?
Authors: Sardoni Claudio 
Published: April 2015

The object of the paper is to explore whether, or to what extent, a Marxian explanation of the current capitalist crisis is possible. The answer is that, although Marx's theory offers important insights to understanding the ultimate causes of capitalist crises, it is not able to provide a fully satisfactory explanation of typical crises of contemporary capitalism.In particular, Marx's analysis cannot account for the long periods of stagnation following the eruption of financial and economic crises. In Marx's analytical context, crises are followed by recovery and growth in a relatively short span of time. It is argued that the main reason for Marx's inability to explain crises of contemporary capitalism is that he developed his analysis by considering free-competitive economies, whereas modern economies are characterized by monopolistic competition. A more satisfactory explanation of the current crisis requires going beyond Marx's original contributions.
Imagining Geographies, Mapping Identities
Authors: Graves Matthew , Rechniewski Elizabeth 
Published: April 2015

The ambition of this issue of Portal is to reach across the methodological boundaries of history, politics, literature and geography to apply their complementary perspectives to the study of identity and its relation to space and place, an aim that involves attempting to identify the many different ways the notoriously slippery concepts of identity and geography may intersect.For this issue we have selected articles that cast a fresh perspective on two areas where identity and geography intersect: the construction of identity through the imaginative recreation of place in literature: Mapping Literary Spaces; and the study of the shifting relationships of centre and periphery, exclusion and inclusion in urban settings and geopolitical confrontations: Social and Political Peripheries.Gerard Toal has written that geography is not a noun but a verb: it does not describe what space is but studies what we do with space, imaginatively and politically. The articles in this issue illustrate the exercise of the literary and political imagination and the role of materiality and memory in the creation of geographic representation. They show too a new awareness of the centrality of space in the constitution of identities, and the need for a new geocritical reading of its discourse, as the interrelations of place and community are played out on the many scales of social and political life, from the local to the global. The special issue is organised thus:IntroductionMatthew Graves (Aix-Marseille University) & Liz Rechniewski (Sydney University): “Imagining Geographies, Mapping Identities.”I.
