Authors: Mahmoudpour Asiyeh , Nafisi Shohreh , Najafi Ezzatollah , Notash Behrouz 
Published: June 2019

AbstractA new mixed-ligand diorganotin(IV) complex, [μ-(4-dpe){Me2Sn(cup)2}2] (1), was synthesized by reacting dimethyltin(IV) dichloride with 1,2-di(4-pyridyl)ethylene (4-dpe) and ammonium N-Nitroso-N-phenylhydroxylamine (cup). The prepared complex was fully characterized by PXRD,1H,13C and119Sn NMR, IR, and UV spectra and elemental analysis (CHN). The structural analysis of complex1by X-ray diffraction showed that this compound consists of centrosymmetric binuclear units that crystallize in the monoclinic system with the space group ofP21/c. Thermal behavior of this complex was interrogated by thermogravimetric and differential thermal analysis (TGA and DTA) under air atmosphere. The study of thermal behavior and luminescence properties of prepared diorganotin(IV) complex exhibited that this complex can be used as a emitting layer in the preparation of optical devices. The prepared coordination compound was used in two different concentrations in the manufacture of two light-emitting diodes (OLEDs).

Abstract
A new Pb(II) complex, [Pb(8-OQ)(4-NB)], where 8-OQ = 8-hydroxyquinolinate, 4-NB = 4-nitrobenzoate, has been synthesized and characterized by elemental analysis, IR spectroscopy, and X-ray single-crystal diffraction. The single crystal X-ray analysis reveals that the complex possesses a tetranuclear Pb4O4 cubane structure. The Pb(II) atom is coordinated by three triply bridging phenolic hydroxyl O atoms of 8-OQ ligands, then the tetranuclear Pb system is formed resulting in a tetrahedral cage. The interaction of complex with HS-DNA in Tris buffer was studied by UV−vis absorption spectrum and fluorescence ethidium bromide displacement experiment with an intrinsic binding constant of 1.52×104 M-1 and a linear Stern–Volmer quenching constant of 6.77×103 M-1. Anticancer activity against MCF-7, HepG-2 and A549 cell lines of complex was also determined by the MTT-based assay. The results showed the complex can inhibit proliferation of these three kinds of tumor cells and is less cytotoxic than cisplatin.
The interaction of morin and morin-5’-sulfonic acid with lead(II): Study of the 1:1 complex formation process in aqueous solution

Published: June 2019

Abstract
This article focuses on the aqueous complexation between two flavonoids (morin and morinsulfonate) and Pb2+ at constant ionic strength I=0.5 M (NaClO4). The determination of stability constants of ML complexes were performed at wide pH range. Two obtained constants are 14.8 ± 0.1 and 15.2 ± 0.1 logarithmic units for morin and morin-5’-sulfonic acid, respectively. For estimating the thermodynamic stability of the complexes studied, the Def2-SV(P)/DFT/PBE0/SMD method has been used. Different computational models were tested to describe the data obtained. The theoretical values of logK reproduce the experimental parameters within reasonable errors.
Personal View: The barn owl — a specialist for studying sensory systems
Authors: Wagner Hermann 
Published: June 2019

Abstract
In this personal view article, the impact of an auditory specialist, the barn owl, to our understanding of sensory processing, especially auditory processing, is discussed from the perspective of a long-lasting career.
In times when research on model systems such as the mouse or the fruit fly, both generalists for most of the behaviors examined, celebrates big successes, one may ask what the work on animals occupying specialized niches, “specialists”, can contribute to advance our knowledge about sensory systems. A specialist in this context is an animal that occupies a certain ecological niche and shows corresponding adaptations in anatomy and physiology. This article presents a personal view on the impact of the work on such a specialist. In my article I shall focus on audition in the barn owl, a specialist for hunting by listening.
I started my scientific career in 1979, working with houseflies, and have worked with barn owls since my time as a postdoc at the California Institute of Technology (“Caltech”, Pasadena, CA, USA) in 1985. My interest in specialists derived from my work as an ornithologist when I realized that adaptations like the long and curved bill of the curlew help animals to occupy certain ecological niches. I wanted to understand in a formal sense, and in comparison to engineering, how evolution shapes such specializations.
Panentheisms, Creation and Evil
Authors: Attfield Robin 
Published: June 2019

Abstract
Can panentheism cope with the problem of evil? This problem is often understood as one for classical theists, who maintain that the cosmos, together with its evils, was created by an all-powerful and benevolent God. For classical theists need to reconcile the world’s evils with divine creation. But corresponding problems re-emerge for theologies of both pantheistic and panentheistic kinds. Thus a problem arises for panentheists, with their teachings about a close relation between God and the cosmos. The closer the relation, the more intense the problem. Thus panentheists who regard the world as necessary to or part of God must hold that its evils are likewise necessary to or part of God. I explore in this paper whether panentheism can overcome the corresponding problem. This exploration involves sifting different varieties of panentheism. While for some varieties the problem is insoluble, this turns out to be less so for others, which retain central features of classical theism, while stressing interaction between God and the created world. In particular, grounds will be offered for holding that the version of panentheism put forward by Jürgen Moltmann and by Arthur Peacocke is defensible and can overcome this problem.
The Emotional Impact of Evil: Philosophical Reflections on Existential Problems
Authors: Colgrove Nicholas 
Published: June 2019

Abstract
In The Brothers Karamazov, Dostoyevsky illustrates that encounters with evil do not solely impact agents’ beliefs about God (or God’s existence). Evil impacts people on an emotional level as well. Authors like Hasker and van Inwagen sometimes identify the emotional impact of evil with the “existential” problem of evil. For better or worse, the existential version of the problem is often set aside in contemporary philosophical discussions. In this essay, I rely on Robert Roberts’ account of emotions as “concern-based construals” to show that theistic philosophers can effectively address the existential problem (and so, the problem should not be set aside). In fact, addressing the emotional impact of evil is crucial, I argue, given that resolving just the impact of evil on agents’ beliefs about God constitutes an incomplete response to the problem of evil.
A painful foot with diagnostic and therapeutic consequences
Authors: Allen Sara Maria , Bédos Ulvin Line , Sabel Wenche , Popperud Trine Haug , Ørstavik Kristin 
Published: June 2019

Abstract

Background
A wide range of patients are referred to multidisciplinary pain clinics. An important part of the work-up is a thorough pain analysis that might reveal a specific cause for chronic pain.

Method
We describe a patient with chronic pain in one foot after a light trauma and repeated surgery. However, careful examination revealed symptoms and clinical finings in both feet. This led to referral to a University Hospital and the diagnosis of a chronic neurologic condition explaining both symptoms and findings. The diagnosis of this condition has implications both for further follow-up for this patient and possibly also other family members.

Implications
Professionals working in the pain-field should be aware of diagnosis that might partly explain increased pain or complications after surgery.
Chronic Fatigue Syndrome and chronic pain conditions – vitally protective systems gone wrong
Authors: Pedersen Maria 
Published: June 2019

Abstract
Chronic Fatigue Syndrome (CFS) and chronic pain syndromes represent major health problems in society. These conditions are disabling and strongly associated with low quality of life. Even though CFS and chronic pain are separate conditions, they have strikingly much in common. Both pain and fatigue are important sensations with protective value in an acute situation. It can be life-threatening not to be aware of them. However, as these symptoms become chronic, their protective roles decrease and instead they become health problems. Our understanding of the perception of pain and fatigue has shifted through the years, from a dualistic biomedical point of view to a holistic biopsychosocial understanding. This combined with the increasing evidence of how our brain works in a predictive/anticipatory manner, gives a deeper understanding of why treatments like cognitive behavior therapies and stress relief therapies can help these patients recover to better health.
Chronic low back pain is highly individualised: patterns of classification across three unidimensional subgrouping analyses
Authors: Rabey Martin , Smith Anne , Kent Peter , Beales Darren , Slater Helen , O’Sullivan Peter 
Published: June 2019

Abstract

Background and aims
Chronic low back pain (CLBP) is a complex disorder where central and peripheral nociceptive processes are influenced by factors from multiple dimensions associated with CLBP (e.g. movement, pain sensitivity, psychological). To date, outcomes for treatments matched to unidimensional subgroups (e.g. psychologically-based) have been poor. Therefore, unidimensional subgrouping may not reflect the complexity of CLBP presentations at an individual level. The aim of this study was therefore to explore patterns of classification at an individual level across the three previously-published, data-driven, within-dimension subgrouping studies.

Methods
Cross-sectional, multidimensional data was collected in 294 people with CLBP. Statistical derivation of subgroups within each of three clinically-important dimensions (pain sensitivity, psychological profile, pain responses following repeated spinal bending) was briefly reviewed. Patterns of classification membership were subsequently tabulated across the three dimensions.

Results
Of 27 possible patterns across these dimensions, 26 were represented across the cohort.

Conclusions
This result highlights that while unidimensional subgrouping has been thought useful to guide treatment, it is unlikely to capture the full complexity of CLBP. The amount of complexity important for best patient outcomes is currently untested.

Implications
For clinicians this study highlights the high variability of presentations of people with CLBP at the level of the individual. For example, clinician’s should not assume that those with high levels of pain sensitivity will also have high psychological distress and have pain summation following repeated spinal bending. A more flexible, multidimensional, clinically-reasoned approach to profile patient complexity may be required to inform individualised, patient-centred care. Such individualised care might improve treatment efficacy. This study also has implications for researchers; highlighting the inadequacy of unidimensional subgrouping processes and methodological difficulties in deriving subgroups across multidimensional data.

Authors: Banerjee Aritra , Puppala Anand J. , Hoyos Laureano R. , Likos William J. , Patil Ujwalkumar D. 
Published: June 2019

Abstract
Robust design of pavement sections underlain by high-plasticity subgrade soils requires determination of subgrade resilient modulus over a wide range of suction to account for seasonal and diurnal variation of moisture. A laboratory experimental apparatus capable of performing suction-controlled repeated load triaxial tests at high suction (5 to 600 MPa) has been developed by integrating automated vapor pressure control to the specimen gas phase within a cyclic triaxial setup. The system eliminates limitations on applicable upper-bound suction that exist in more commonly adopted axis-translation approaches. This article describes the experimental setup, its working principle, and test procedures. Results are presented for a high-plasticity clayey soil to demonstrate testing capability for suction ranging from 5 to 100 MPa. Results show repeatability having an average coefficient of variation of less than 6 % for all loading sequences.
Testing and Evaluation on Dynamic Response of a New Modified Soil Subgrade under Freeze-Thaw Cycles

Published: June 2019

Abstract
Dynamic response analysis is an effective method of evaluating the strength, deformation, and stability of subgrade under repeated vehicle traffic loads. It is usually premised on the results of a field test, which not only requires a lot of manpower and money but also can be easily affected by extraneous factors. In this study, a laboratory test was conducted in order to examine the dynamic response of a new type subgrade: silty clay (SC) modified by fly ash and crumb rubber (RFS). A novel tester was adopted in order to simulate and impulse traffic loads with different vehicle speeds/weights on subgrade materials. In addition, the dynamic stress and acceleration responses of RFS and SC were analyzed under varying speeds and axle loads under 0–5 freeze-thaw (F-T) cycles. Thereafter, scanning electron microscope tests were conducted to bring about clarity regarding the effect on the internal structural changes of two test soils in order to elaborate on the reasons for these dynamic response changes. According to the findings of these tests, the dynamic stability of SC is better than the RFS before F-T cycles. However, the RFS provides better resistance to F-T dynamic stability as the F-T cycle goes on. In particular, the RFS is more suitable for subgrade filling in seasonally frozen regions. Against this backdrop, the current article proposes a convenient method to evaluate the dynamic response of subgrade in laboratory, besides providing a reference for the dynamic characteristics of RFS.

Published: June 2019

Abstract
In order to derive the anisotropic damage model of soft and hard composite rock and to study the influence law of damage on the deterioration degree of material mechanical parameters in different directions, the transversely isotropic elastic constitutive equation was corrected by two sets of damage variables in the local coordinate system of bedding plane. By coordinate transformation, an effective stress–strain relationship in the global coordinate system was formed. The rationality of the damage model was verified by the results of uniaxial compression test. The results show that (1) The damage of soft and hard composite rock has transversely isotropic characteristics. (2) The change trend of damage variables varying with strain is closely related to each stage of the damage process; at the same strain level, the damage variables increase first and then decrease with the increase of the bedding plane’s dip angle (0°~90°) and have a good corresponding relation with the damage model. (3) The strength and deformation parameters calculated by the damage model of soft and hard composite rock can reflect the test results well and have obvious anisotropy. The calculated curves before failure are also consistent with the experimental results. (4) Through the damage model, the stress–strain relationship at each dip angle can be determined by the two sets of deformation parameters for the bedding plane’s dip angles of 0° and 90°. Because the damage deterioration effect during loading process is considered, the mechanical behavior of the specimens after failure can be predicted, which has some guiding significance for the experimental research, theoretical calculation, and engineering construction based on soft and hard composite rock.
Assessment of Magnetically Induced Displacement Force and Torque on Metal Alloys Used in Medical Devices
Authors: Woods Terry O. , Delfino Jana G. , Rajan Sunder 
Published: June 2019

Abstract
Millions of patients receive magnetic resonance imaging (MRI) scans each year, and thousands of healthcare professionals and other individuals also routinely enter the magnetic resonance (MR) environment. The electric and magnetic fields used by the MR system to create MR images produce hazards that must be considered to determine whether a medical device or other object may safely be used in or near an MR system. Magnetically induced deflection force and torque are two of the hazards that must be addressed to determine the MRI safety of any device or object that will be used in or near an MR system. This article presents magnetically induced force and torque test results for a variety of common medical implant alloys. For seven of the eleven tested alloys, magnetically induced force is less than the device weight in any current clinical 1.5, 3.0, and 7.0-T MR system. For the other alloys, the magnetically induced force is greater than the device weight in some MR systems. The torque test results for the tested alloys demonstrate that for static magnetic fields of 3.0 T or less, the magnetically induced torque will always be less than the worst case torque produced by gravity. These results may be leveraged in MRI safety assessments for medical devices and other objects composed of those alloys and conforming to the same ASTM specifications and may be used as part of the information needed to generate MR Conditional labeling for the devices.
A perícia e o perito criminal contábil: Instrumentos a serviço da justiça
Authors: Silva Thiago Henrique Costa 
Published: June 2019

Este trabalho tem como objetivo principal evidenciar o papel da perícia criminal, sobretudo da perícia criminal contábil, como instrumento jurídico e técnico-científico de combate à criminalidade e auxílio à justiça, sendo elaborado em uma abordagem qualitativa, subsidiada por pesquisa bibliográfica e análise indireta de dados. Em uma sociedade em que a criminalidade avança no sentido de se especializar para garantir altos ganhos e a consequente impunidade, é papel do Estado buscar meios de combate ao crime organizado. Nesse sentido, a perícia criminal contábil tem o importante papel de elucidar os crimes que ocasionam o maior prejuízo para a sociedade, àqueles que envolvem sonegação, desvio ou ocultação de dinheiro, que deveriam ir ao encontro do interesse público e da efetivação de políticas públicas. O Código de Processo Penal é taxativo quanto à necessidade de perícia criminal nos casos em que a infração deixar vestígios e, sendo a contabilidade a ciência responsável pelo registro, controle e caminho do patrimônio, a perícia criminal contábil ocupa lugar central nos processos que envolvem crimes contra o sistema financeiro ou contra a ordem econômica e tributária. Dessa forma é cada vez mais necessário que os Estados invistam nas carreiras das polícias técnico-científicas e na contratação e especialização de peritos criminais, que elaborarão laudos capazes de interpretar vestígios, produzindo provas em favor da verdade. AbstractThe main objective of this paper is to highlight the role of criminal forensics, especially forensic accounting, as a legal and technical-scientific instrument to combat crime and assisting justice, being elaborated in a qualitative approach, subsidized by bibliographical research and documental. In a society that criminality progresses in order to specialize guaranteeing high gains and the consequent impunity, it is the role of the state to seek ways of combating organized crime. In this sense, criminal accounting expertise has the important role of elucidating crimes that cause the greatest harm to society, to those involving evasion, misappropriation or concealment of money, which should meet the public interest and the implementation of public policies. The Code of Criminal Procedure is taxactive regarding the need for criminal expertise in cases where illegality leaves traces and, the accounting being the science responsible for registration, control and patrimony path, forensic accounting occupies central place in the processes which involve crimes against the financial system or against the economic and tributary order. In this way it is increasingly necessary for States to invest in the careers of technical-scientific police and in the hiring and specialization of criminal experts, who will produce reports capable of interpreting traces, producing proof for the truth.

Authors: Segatto Breno Rodrigues 
Published: June 2019

Nesse trabalho busca-se averiguar se o Tracker é confiável na elaboração de laudos periciais, em casos envolvendo vítimas de queda de alturas, quando esses são captados por câmeras de vídeo monitoramento/segurança. Para isso, foram investigados na literatura os dados extraídos do Tracker, principalmente as grandezas físicas como aceleração e velocidade para corpos em queda. Recomenda-se a não utilização do Tracker quando a aceleração da gravidade obtida pela análise das imagens seja consideravelmente destoante do padrão medido na localidade do incidente (precipitação). AbstractIn this work we try to make sure that the Tracker is reliable in the elaboration of forensic reports involving victims from fall from high when these are recorded by security/ monitoring video cameras. For that, was investigated in the literature the data extracted by Tracker, mainly the physics quantities as acceleration and velocity to bodies in fall. We recommend the non use of the Tracker when the acceleration of the gravity obtained by video analyses be considerable different from the standard measured in the incident (precipitation) location.
