Authors: Sharpley Christopher , Bitsika Vicki , Jesolola Emmanuel , Agnew Linda 
Published: September 2016

Aim of the studyTo describe the prevalence and factor structure of anxiety-depression in a community sample and to derive indicators for treatment planning.Subject or material and methodsA sample of 398 members of the Electoral Roll for the New England region of Australia were recruited at random and completed the Zung Self-rating Anxiety Scale and the Zung Self-rating Depression Scale.ResultsThe prevalence of anxiety-depression was 28.1%, over twice that for either anxiety or depression alone. The anxiety-depression construct was comprised of four underlying factors: Cognitive Agitation & Depressed Mood, Pessimism, Cardiovascular Reactivity, and Pain & Sleep Disturbance. There were different patterns of these four factors across Anxiety-only, Depression-only and combined anxiety-depression, with evidence for a unique symptomatological profile for participants with clinically significant levels of anxiety-depression.DiscussionAnxiety-depression comorbidity was relatively common in this community sample of Australians, with over a quarter of participants meeting the cutoff for clinically significant scores on the combined SAS-SDS construct. These results also highlight the need to consider the presence of clinically significant anxiety-depression as representing a larger proportion of this sample than either anxiety or depression alone.ConclusionsTreatment decisions for anxiety and depression need to go beyond consideration of the two disorders separately to include the underlying factor severity of the combined construct of anxiety-depression.
Borderline functioning and life trauma: a structural approach
Authors: Schiltz Lony , Schiltz Jang 
Published: September 2016

Aim of the studyThe general aim of a multiannual research project was the exploration of the links between traumatizing biographic events and the current functioning of personality. It comprehended an exploratory study with N=206 persons suffering from exclusion and marginalization, followed by a confirmatory study with N=195 persons. We present the confirmatory results, as well as a meta-analysis of the exploratory and confirmatory study.Subject or material and methodsBoth studies were based on an integrated quantitative and qualitative research methodology, combining a semi-structured biographic interview, psychometric scales (HADS, Index of Well-Being) and a projective test (Rotter’s Incomplete Sentences Blank). We developed original rating scales allowing passing from qualitative analysis to the use of inferential and multidimensional statistics.ResultsWith the help of non parametric statistical procedures we could draw out differential types of personality functioning based on prevalent defense mechanisms and coping strategies, either linked to a succession of traumatic events, such as neglect, maltreatment and multiple losses occurring since childhood, or either to recent catastrophes. Our results supported the traumatogenic hypothesis of borderline functioning and pointed towards a partial overlapping of the concepts of splitting and dissociation.DiscussionThe discussion is about the pertinence of the results in the context of the current assimilation of borderline personality functioning with complex post-traumatic states comprising a strong dissociative component and also of the revision of categories of the DSM related to different post-traumatic syndromes.ConclusionsThe conclusion points to tracks for future clinical research.
Innovation System Reform in Indonesia and Vietnam: A new Role for Universities?
Authors: Baark Erik 
Published: September 2016

<p>This paper introduces the importance of the role of universities in emerging economies such as Indonesia and Vietnam, underscoring the need for universities to contribute more extensively to the dynamic development of innovation systems. The theoretical approach is a functional analysis of innovation systems, identifying essential issues that call for recognition among policymakers and in society generally. Innovation systems in Indonesia and Vietnam share some weaknesses, particularly in comparison with innovation systems in more advanced countries. There is limited ability to mobilize the resources required for innovation, as the investment in research and development as percentage of GDP is relatively low and dominated by public funding with little contribution from private sources. Financial regulation for universities seriously hampers the development of university–industry linkages. It is essential that universities gain more autonomy in order to move beyond their current role in training of skilled human resources to providers of innovation.</p>

Abstract
Corrosive behavior in reinforced concrete specimens containing two agricultural byproducts, rice husk ash, and water extracted from manioc, called mandioca brava in Brazil, was investigated by accelerated corrosion tests in a modified immersion assay. The rice husk ash and mandioca brava were characterized by infrared analysis and X-ray diffraction technics. The carboxylate and silanol functional groups were detected in these agricultural byproducts and these functional groups were proposed here as a main cause of inhibition of the accelerated corrosion that occurred during a modified immersion assay. The mass loss from steel bars in concrete specimens after accelerated corrosion tests confirm the synergistic effect of rice husk ash and mandioca brava when used together in a concrete mixture against the corrosion. Anodic polarization measurements of CA-50 steel bars in simulated pore solutions indicated that the presence of these agricultural byproducts offered anticorrosive protection.

Published: September 2016

Abstract
To effectively investigate the mechanical performance of asphalt pavements, software named SAFEM with a user friendly graphical user interface (GUI) was developed. It is based on the semi-analytical finite element (FE) method, which is a three-dimensional FE algorithm that only requires a two-dimensional mesh by incorporating the Fourier series in the third dimension. SAFEM is able to analyze static and dynamic responses of asphalt pavements under stationary or moving loads. Besides linear elasticity, a viscoelastic material model for asphalt layers has also been integrated. Verification was carried out to test and explore the functionality of the software package. We showed that SAFEM is an accurate tool for the fast prediction of asphalt pavement responses, such as the surface deflection and the strain/stress at response points. Furthermore, SAFEM provided a flexible, robust platform for the future development in the numerical simulation of asphalt pavements.

Abstract
Improvement of soft clay by mixing with cement is widely adopted in Thailand to increase the strength and reduce the settlements. The improved soft clay exhibits better strength and permeability properties; however, the improved soil exhibits low tensile strength and brittle behavior. On the other hand, it is known from the literature that geosynthetics have been used for soft soil improvement in conjunction with stone column (SC) and sand compaction pile (SCP) techniques. The lateral deformation of SC and SCP could be significantly decreased by geosynthetic encasement; therefore, the vertical load could be efficiently transferred to deeper soil layers. In this study, a series of unconfined compression tests were performed on cement-mixed clay specimens with a diameter of 75 mm and height of 150 mm. Cement contents used were 10 %, 15 %, and 20 % by dry mass of clay. The water-to-cement ratio used was 0.6 and total clay water contents were 105 % for the normal-water-content case and 160 % for the high-water-content case. A polyester geogrid was used to encase the specimens. Prior to the test, specimens were cured for 7, 14, and 28 days. It is found that the geogrid encasement has enabled the soil samples to sustain the axial stress for large axial deformations, even after the local failure in the cement-mixed clay matrix. On the other hand, the unreinforced specimens exhibited strain-softening behavior with a great reduction in axial stress with increasing strain. Encasements with geogrids were found to substantially increase the ductility of cement-mixed clay.

Abstract
Graphene has generated great excitement in the scientific community due its unique mechanical and electronic properties, and also the availability of bulk quantities of graphene as both colloidal dispersion and powder. With the development of relatively high yield and defect-free synthesis methods, this exciting material is ready for practical application in the preparation of polymer nanocomposites. Here, we reported on the mechanical performances of epoxy nanocomposites which have been reinforced with exfoliated graphene nano platelet (GNP) and reduced graphene oxide (RGO) at a loading of 0 to 0.5 wt. %. A soft molding method was used for the preparation of epoxy nanocomposites. The reinforcing effects of GNP and RGO on epoxy resin were examined by tensile testing and dynamic mechanical analysis (DMA). The morphology of the epoxy/GO and epoxy/RGO nanocomposites were investigated using a scanning electron microscope (SEM). A significant improvement on mechanical properties of epoxy/GO and epoxy/RGO nanocomposites was observed at low GNP and RGO loading. Contrary to the literature, the ultimate tensile strength values have mainly decreased, although the Young’s modulus has improved. Dynamic mechanical analysis has shown that with the addition of both GNP and RGO, storage modulus was significantly enhanced at 40  °C. The loss factor was almost not affected by both RGO and GNP loading. SEM investigation of the fractured surface indicates that GNP and RGO fillers are dispersed uniformly in the epoxy matrix.

Published: September 2016

Abstract
Guizhou, China, is known for the abundance of subterranean drainage systems with sinkholes. Sinkholes may develop when acidic water starts to dissolve the surface of bedrock or bedding planes. The dissolution characteristics of limestone play a crucial role in the development of sinkholes. The main objective of this study was to develop a quantitative tool for evaluating the dissolution ability for sinkhole formations in the karst regions of Guizhou. The present study investigates a number of properties of limestone that may influence the dissolution in the karst regions of Guizhou. Over 200 rock samples were collected and tested to determine the CaO/MgO ratio, clast content, clastic/matrix ratio, primary porosity, permeability, and fracture density. A quantitative approach was developed to synthesize the influences of these multiple factors to establish the order of the limestone solubility in different regions of Guizhou via numerical modeling using the analytical hierarchy process (AHP) theory. It was found that the solubility of the karstic limestone from different geological formations was in the following descending order: Carboniferous Huanglong-Maping Formation, Permian Qixia-Maokou Formation, Cambrian Qingxudong Formation, and Triassic Yongningzhen Formation. As the water-bearing capacity of the geological formations in these regions is closely associated with underground cavern and sinkhole formations, the approach explored in the present study may have strong implications for the exploration and utilization of karst groundwater resources.
A Modified Weibull Stress Approach to Determine the Reference Temperature in a Pressure Vessel Steel
Authors: Ruggieri Claudio , Dodds Robert H. 
Published: September 2016

Abstract
This work describes a micromechanics methodology based upon a local failure criterion incorporating the effects of plastic strain on cleavage fracture coupled with the statistics of microcracks to correct effects of constraint loss on fracture toughness and to determine the reference temperature, T0, based on the master curve procedure. The methodology approaches the modeling of cleavage fracture from the point of view of a coupling between the local plastic strain and the number of eligible Griffith-like microcracks nucleated from brittle particles dispersed into the ferrite matrix. A modified Weibull stress, ˜σw, incorporating the effects of plastic strain on cleavage fracture emerges as a probabilistic fracture parameter to define conditions leading to (local) material failure. Fracture toughness testing conducted on an A515 Grade 65 pressure vessel steel provides the cleavage fracture resistance data in terms of Jc—values needed to estimate T0. Very detailed non-linear finite-element analyses for 3D models of the fracture specimens provide the relationship between ˜σw and J from which the variation of fracture toughness across different crack configurations is predicted. For the tested material, the modified Weibull stress methodology yields estimates for the reference temperature, T0, from small fracture specimens, which are in very good agreement with the corresponding estimates derived from testing of much larger crack configurations.
Duplex Titanium Oxide Layers for Biomedical Applications

Published: September 2016

Abstract
This article presented the results of Ti Grade 2 oxidation with the duplex/hybrid method, which combined fluidized bed atmospheric diffusive treatment (FADT) and treatment with plasma methods (PVD). The process was realized to form a titanium diffusive layer saturated with oxygen in the diffusion process and to produce a tight homogeneous oxide coating on Ti substrate, deposited with the magnetron spraying technique. The techniques applied made it possible to combine the synergetic effects of the layers generated and to reduce the stresses in the area of the PVD coating/oxidized Ti substrate interface. In addition, the processes influenced the decrease in the surface roughness parameter and the increase in substrate bio-compatibility, which resulted in easier hydroxyapatite clusters deposition. The diffusion process was realized in Al2O3 fluidized bed reactor, at 913 K for 8 h with air atmosphere, while the deposition of the oxide coatings was realized with magnetron sputtering, with the use of TiO2 target at a pressure of 3 × 10−2mbars. In order to assess the effects of Ti hybrid oxidation, microscopic (AFM, SEM, TEM-EFTEM), spectroscopic (GDOS), and X-ray tests (XRD, sin2Ψ) were performed. The coatings formed had structure, with a Tiα(O) diffusion zone and a TiO2 rutile and anatase oxide zone deposited on the substrate. It was concluded that hybrid method of duplex coatings formation (FADT + PVD) leads to reducing oxide layer defects after fluidized bed heat treatment and to generating a tight homogeneous layer with a favorable state of stress, which results in improving the bio-compatibility of the generated substrate, important from the biomedical applications point of view.
Microstructural Characterization of Ferrous Materials Forged by the Damascus Technique
Authors: Strobl S. , Haubner R. 
Published: September 2016

Abstract
Damascus steels are related to composites which combine the properties of diverse steel qualities. By forging steel plates with different compositions, in particular differences in the carbon content, a multilayered workpiece is manufactured. Forging of cast iron has not been common because of its low melting point and brittleness at lower temperatures. Wolfgang Scheiblechner, a blacksmith from Palfau in Austria, combined ductile cast iron and soft iron to a unique composite material, which was investigated by means of metallographic methods. The intersections of cast iron and iron are of high interest, where carbon diffusion from ductile cast iron (graphite 100 % C) to soft iron (0 % C) takes place. In this case, all the microstructures characteristic for cast irons, steels, and soft iron were present. The microstructures were additionally influenced by forging and quenching. The cast iron region was dominated by nodular graphite and bainite; ledeburite was observed occasionally. The soft iron regions showed coarse equiaxed ferrite and grain boundary cementite. In the transition areas, ferrite showed a wide variety of shapes, and the microstructure changed from hypereutectoid to hypoeutectoid steel. The various microstructures were characterized by light optical microscopy and confirmed by Vicker's microhardness measurements.

Published: September 2016

AbstractOur remarkable ability to process complex visual scenes is supported by a network of scene-selective cortical regions. Despite growing knowledge about the scene representation in these regions, much less is known about the temporal dynamics with which these representations emerge. We conducted two experiments aimed at identifying and characterizing the earliest markers of scene-specific processing. In the first experiment, human participants viewed images of scenes, faces, and everyday objects while event-related potentials (ERPs) were recorded. We found that the first ERP component to evince a significantly stronger response to scenes than the other categories was the P2, peaking ∼220 ms after stimulus onset. To establish that the P2 component reflects scene-specific processing, in the second experiment, we recorded ERPs while the participants viewed diverse real-world scenes spanning the following three global scene properties: spatial expanse (open/closed), relative distance (near/far), and naturalness (man-made/natural). We found that P2 amplitude was sensitive to these scene properties at both the categorical level, distinguishing between open and closed natural scenes, as well as at the single-image level, reflecting both computationally derived scene statistics and behavioral ratings of naturalness and spatial expanse. Together, these results establish the P2 as an ERP marker for scene processing, and demonstrate that scene-specific global information is available in the neural response as early as 220 ms.

Authors: McCarty Carolyn A. , Zatzick Douglas , Stein Elizabeth , Wang Jin , Hilt Robert , Rivara Frederick P. ,   for the Seattle Sports Concussion Research Collaborative
Published: September 2016

BACKGROUND AND OBJECTIVES:
Postconcussive and co-occurring psychological symptoms are not uncommon after sports-related concussion and are associated with functional impairment and societal costs. There is no evidence-based treatment targeting postconcussive symptoms in children and adolescents. The goal of this study was to test a collaborative care intervention model with embedded cognitive–behavioral therapy, care management, and psychopharmacological consultation. We hypothesized that patients in collaborative care would demonstrate greater reductions in postconcussive, depressive, and anxiety symptoms and improvement in functioning over the course of 6 months, compared with usual care control.

METHODS:
Patients aged 11 to 17 years with persistent symptoms ≥1 month after sports-related concussion were randomly assigned to receive collaborative care (n = 25) or care as usual (n = 24). Patients were assessed before randomization and after 1, 3, and 6 months. Groups were compared over time via linear mixed effects regression models.

RESULTS:
Adolescents assigned to collaborative care experienced clinically and statistically significant improvements in postconcussive symptoms in addition to functional gains at 6 months compared with controls. Six months after the baseline assessment, 13.0% of intervention patients and 41.7% of control patients reported high levels of postconcussive symptoms (P = .03), and 78% of intervention patients and 45.8% of control patients reported ≥50% reduction in depression symptoms (P = .02). No changes between groups were demonstrated in anxiety symptoms.

CONCLUSIONS:
Orchestrated efforts to systematically implement collaborative care treatment approaches for slow-to-recover adolescents may be useful given the reductions in postconcussive and co-occurring psychological symptoms in addition to improved quality of life.
