Experimental assessment of the static stiffness of machine parts and structures by changing the magnitude of the hysteresis as a function of loading
Authors: Stejskal Tomas , Dovica Miroslav , Svetlik Jozef , Demec Peter 
Published: December 2019

Abstract
Static stiffness is determined by one-sided loading and unloading of machine parts relative to the selected base. For each structure, there will be some loss of potential energy due to the dissipative forces that occur during the loading inside the structure. This loss is manifested in hysteresis in the stiffness diagram. A new approach to the assessment of static stiffness consists in gradual, bilateral loading and unloading of the structure through the effect of static forces of different magnitude. In this process, the stiffness hysteresis varies, depending on the intrinsic nature of the dissipative forces, a specific property suitable for assessing the condition of machines.

Published: December 2019

AbstractThe current study focuses on the parametric optimization of electroless Ni-Co-P coating considering surface roughness as a response using Box-Behnken Design (BBD) of experiment. The two bath parameters namely the concentration of cobalt sulphate and sodium hypophosphite were varied along with the bath temperature to predict the variation in surface roughness. Analysis of variance (ANOVA) method has been applied to determine the interactions of the substantial factors which dominate the surface roughness of the coating. The process parameters for surface roughness of the coating were optimized by successfully utilizing the statistical model of Box-Behnken Design (BBD) of experiment. From the BBD model, the optimum condition for the deposition of the coating has been evaluated. In that specific condition, the surface roughness of the as-deposited coating is found to be 0.913μm. Scanning Electron Microscopy (SEM), Energy Dispersive X-ray Spectroscopy (EDX), and X-Ray Diffraction (XRD) study have been utilized to characterize the electroless Ni-Co-P coating deposited in optimized condition.
Nature at the Limits of Science and Phenomenology
Authors: Suarez David 
Published: December 2019

AbstractKant and Heidegger argue that our subjectivity escapes scientific explanation, while also providing the conditions that enable it. This understanding of the relationship between subjectivity and science places limits on the explanatory scope of the sciences. But what makes transcendental reflection on the structure of subjectivity possible in the first place? Fink argues that transcendental philosophy encounters its own limits in attempting to characterize its own conditions of possibility. I argue that the limits of science and transcendental philosophy entail that nature cannot be conceived as a specific object, or as a totality of objects in the world, but only as the ontological ground of phenomenal manifestation in general. Nature is not identical with anything discoverable in either science or phenomenology; it is, rather, the origin from which discovery of phenomena proceeds.
Are the unhappy unemployed to blame for unrest? Scrutinising participation in the Arab Spring uprisings
Authors: Paasonen Kari 
Published: December 2019

Abstract
Unemployment is considered a significant driver behind the so-called Arab Spring, and more generally behind protests, rebellions, and civil wars. However, the empirical evidence of this hypothesised link between unemployment and political instability is scant and contradictory. This article contributes to filling this gap. In addition, this is the first study which will concentrate on the role of unemployment in the case of the Arab Spring uprisings. The study utilises regression analysis and several survey data sets. The results show that compared to the employed, the unemployed are not more likely to have participated in the Arab Spring unrests or protests in the Arab world in general. Further analyses reveal that, as expected, the unemployed are less satisfied with life and not particularly interested in politics. In turn, being dissatisfied with life does not influence the likelihood that an individual revolts, but those interested in politics are considerably more active protesters. Taken together, the results indicate that the Arab unemployed were unhappy, but due to their low interest in politics this dissatisfaction did not drive them to the streets. These findings together with some earlier results from different corners of the world suggest that the linkage of unemployment and political instability is remarkably weaker than often assumed.
The layer-structure transition of glass-fiber-reinforced composite materials

Published: December 2019

Abstract
This study aims to investigate whether the layer-structure transition governed by fiber orientation is caused by the change in the elongational strain field or by the change in the shear strain field during the filling process in injection molding using short-fiber-reinforced thermoplastic resin. To this end, a polyamide 6 containing 30 wt% of short-fiber glass was compounded, and a simple plate was injection-molded. The fiber orientation of the plate was observed via X-ray computed tomography, and the fiber orientation distribution was quantified as fiber orientation tensors. The transition of the layer structure, which is mainly composed of the shell layer and core layer during the filling process, was evaluated on the basis of the fiber orientation distribution. The experimental results were compared with velocity information obtained via flow analysis of elongational and shear strain fields. The results showed that flow induction affects the layer-structure transition and that the transition occurs because of changes in the elongational strain field and not because of changes in the shear strain field during the filling process. Thus, the elongational strain field is an important consideration when modeling fiber orientation.

Abstract
In this paper, a model reference adaptive sliding mode control method is proposed for a variable cycle engine (VCE) which is a MIMO system with uncertainties and external disturbances. The reference model is designed based on optimal LQR method to provide ideal reference states. An adaptive sliding mode controller (ASMC) is designed for model reference adaptive control structure, which the adaptive law is derived based on Lyapunov function to estimate the unknown upper bound of uncertainties and external disturbances. Simulation results for VCE demonstrate the performance and fidelity of the proposed method.

The study included 24 patients from the anesthesiology and resuscitation ward of the Federal Research and Clinical Center of Intensive Care Medicine and Rehabilitology. Blood was acquired from the patients for standard tests, and all further tests were performed in vitro. The images of red blood cells were obtained using the atomic force microscope «NTEGRA Рrima» (NT-MDT, Russia) in semi-contact mode.Results. Patients from the anesthesiology and intensive care ward with traumatic brain injury, ischemic and hemorrhagic stroke, cerebral edema, and post-hypoxic encephalopathy had different blood cell shapes and localized defects of different topology on the surface of erythrocyte membranes including defects of pallor, torus, and nanostructure.Conclusion. In this pilot study we have shown that several defects represent the trigger mechanisms for the development of a total membrane damage. Local topographic defects of nanostructures and abnormalities of erythrocyte morphology are irreversible. The number and quality of these abnormalities may eventually be used as a diagnostic and prognostic biomarker of pathological processes.

Aim. To study the distribution and spatial organization of dentate gyrus (DG) astrocytes and CA4 area of hippocampus of Wistar rats following 20-minute occlusion of common carotid arteries (OCCA) compared to sham-operated control animals.Material and methods. Histological (Nissl staining with hematoxylin and eosin), immunohistochemical (GFAP, MAP-2) and morphometric methods were used. Astrocytes and neurons in control (sham-operated animals, n = 5) group, after 6 hours (n=5), 1 days (n=5), 3 days (n=5), 7 days (n=5), 14 days (n=5) and 30 days (n=5) after 20-minute OCCA were studied on thin (4 µm) serial frontal sections of the hippocampus. Fractal analysis (ImageJ 1.52; fraclac 2.5 plugin) was used to obtain additional quantitative information on the spatial organization of astrocyte networks. Statistical hypotheses were tested using nonparametric criteria.Results. 30 days after the 20-minute OCCA, only 5.3% of CA4 neurons were irreversibly destroyed and the total numerical density of DG granular cells remained at the control level. Hypertrophy and increased complexity of the spatial organization of astrocyte processes were observed 6 hours and 1 day after OCCA and persisted for 30 days. Astrogliosis was accompanied by an increased relative area of GFAP-positive material and fractal dimension and reduced lacunarity of the astrocyte network. The latter was especially evident in 1, 14 and 30 days after the OCCA.Conclusion. After the 20-minute OCCA, the density of GFAP-positive material increased, the fibroarchitecture reorganized and gained more complexity due to the branching of astrocyte processes. At the same time, the total numerical density of neurons changed only slightly. All this indicated the probable role of astrocytes in post-ischemic activation of natural neuroprotection mechanisms.

Published: December 2019

The presence or development of liver disorders can significantly complicate the course of critical illness and terminal conditions. Systemic hemostatic disorders are common in Intensive Care Units patients with cholestatic liver diseases, so the study of the mechanisms of their development can contribute to the understanding of the development of multiorgan failure in critical illness.The review discusses current data on changes in hemostatic parameters in patients with cholestatic liver diseases, proposes a mechanism for the development of such disorders, which involve interactions of phospholipids with platelet and endotheliocyte membranes. It is suggested that a trend for thrombosis in patients with cholestatic liver disease is due to increased accumulation of bile acids in the systemic circulation. Available data demonstrate that the antiphospholipid syndrome may predispose to the formation of blood clots due to alterations of phospholipid composition of membranes of platelets and vascular endothelial cells by circulating antiphospholipid antibodies. Clarifying the mechanisms contributing to changes of the blood coagulation system parameters in liver disorders will aid to development of optimal correction of hemostatic disorders in patients with chronic liver diseases.

Published: December 2019

The review focuses on the neuroprotective mechanisms of therapeutic hypothermia from the standpoint of metabolic depression and genomic reprogramming of neurons that develop when brain temperature decreases.The concept of hypothermic pre-conditioning based on the development of typical nonspecific reactions for the formation of the cytoprotective phenotype of neurons due to potentially dangerous stimuli, such as ischemia, reperfusion, and hypothermia, was used to explain the effects of low temperatures. The data confirming the role of therapeutic cerebral hypothermia as a technique of selective brain exposure to mild cold for the neuroprotection and correction of temperature balance disorders are shown.The approach to therapeutic hypothermia as a hypothermic pre-conditioning allows to significantly expand the scope of its use in various procedural variants.
High-Grade Metamorphism and Anatexis in the Teletskoe–Chulyshman Belt (Gorny Altai): U–Pb Geochronology, P–T Estimates, and Thermal Tectonic Model

Published: December 2019

Abstract
—A model of the formation of the Teletskoe–Chulyshman metamorphic belt (TCMB) in Gorny Altai has been elaborated. The estimated pressure (not exceeding 3–4 kbar) and temperature (about 740 °C) indicate an increased regional crustal thermal gradient equal to 60–90 °C/km during the formation of the metamorphic belt. The age of migmatites of the Chulyshman complex has been evaluated at 483.9 ± 5.7 Ma (Early Ordovician) by U/Pb (SHRIMP) zircon dating. The paleogeodynamic setting of the TCMB formation and the protolith nature are identified based on the geochemical and petrochemical parameters of the metamorphic rocks. Structural parameters and numerical modeling show that the Chulyshman migmatite–gneiss complex is an apical part of the thermal-dome structure formed under the thermal impact of a magmatic basic heat source in the base of the crust and displaced to the relevant depths via thrusts and crustal extrusion during the Early Ordovician accretion–collision event. Matching the metamorphism parameters and the numerical-modeling results for the crustal thermal regime, we determined the rate of the anatectic front displacement along the thrust to be at least 6 cm/yr.

Postglacial Uplift: Record in the Gravity Field and in Neogene–Quaternary Structures
Authors: Dobretsov N.L. , Vasilevskiy A.N. 
Published: December 2019

Abstract
The history of Quaternary glaciation and postglacial uplift in Fennoscandia is considered in relation to the surface topography, gravity, and number of glacial deposits and is compared to the respective processes in North America. The surface topography and the gravity field are correlated over the Fennoscandian region as a whole and for two reference areas of South Norway and the Kola Peninsula. The gravity field is composed as free-air and Bouguer gravity anomalies using modern global models based on satellite data. The impact of glaciation may be responsible for zoned patterns of both topography and gravity. The glaciation centers of Norway are marked by uplifts reaching 2470 and 1500 m and by circular Bouguer gravity lows of ≤ –200 mGal, which correspond to residual crust thickening. The gravity patterns of the Kola Peninsula and Norway consist of circular and polygonal anomalies caused by both postglacial rebound and rock density variations. The general uplift and related extension of the crust led to the formation of fractures of different sizes, from 100–200 km long and 1–2 km deep fjords in Norway to 1–2 km long and 30–20 m deep local fractures on the Kola Peninsula. The gravity field of central North America is characterized by a generalized map of free-air anomalies within the limits of glaciation and a map of free-air anomalies compiled from the global database. Glaciation and its records in the surface topography and gravity patterns are described in more detail for Wisconsin State (USA), where extension fractures are similar to those on the Kola Peninsula. The models explaining the correlation between postglacial uplift and gravity variations can be further updated using seismic and tectonic data, as it was shown previously for the case of Finland.
