The use of injectable chondroitin sulfate in combination with dosed physical exercise for the treatment of patients with hand osteoarthritis
Authors: Vasilyeva L. V. , Evstratova E. F. , Suslova E. Yu. 
Published: September 2020

Objective: to evaluate the efficiency and the safety of treatment with injectable chondroitin sulfate (ICS) in combination with dosed physical exercise (exercise therapy (ET)) for hand osteoarthritis (HOA).Patients and methods. A study group consisted of 68 patients with HOA; the diagnosis of which was established in accordance with the 1991 American College of Rheumatology (ACR) criteria. The investigators identified two groups: 1) 36 women and 4 men; mean age, 62.2±3.4 years (a study group); 2) 20 women and 8 men; mean age, 61.7±6.5 years (a control group). Group 1 patients received treatment with 25 intramuscular ICS (Chondroguard) injections per cycle and underwent ET under the guidance of a trainer. In the first 3–5 days, the patients could take nonsteroidal anti-inflammatory drugs (NSAIDs). Group 2 patients were prescribed a magnetic therapy cycle (alternating pulsed magnetic field, 15–20-minute hand exposure, a total of 10 sessions). They could also take NSAIDs within the first 3–5 days. A visual analogue scale (VAS, mm) was used to analyze hand pain severity over time: at baseline, at 3 weeks, and at 3 months after the start of treatment.Results and discussion. The dynamics of VAS joint pain was statistically more significant in Group 1 than in Group 2: 69.1±2.83 and 71.1±2.15 mm at baseline; 42.6±1.16 and 57.14±1.96 mm at 3 weeks (p<0.05), and 36.4±2.96 and 62.8±3.26 mm at 3 months (p<0.001). Similarly, Group 1 versus Group 2 showed a greater improvement in indicators, such as a decrease in the duration of morning stiffness in the hands and an increase in their grip strength. No adverse reactions requiring discontinuation of treatment or special therapy were noted in both groups.Conclusion. The investigation showed the advantage of ICS used in combination with ET over magnetotherapy in the treatment of patients with HOA.

Published: September 2020

Objective: to assess the relationship between bone mineral density (BMD) and the muscular apparatus in male patients with coronary heart disease (CHD).Patients and methods. The investigation enrolled 79 male patients (median age, 63 [57; 66] years) with an established diagnosis of CHD verified by coronary angiography.Muscle mass was assessed by multispiral computed tomography, by determining the axial muscle tissue area (cm2 ) at the level of LIII. Muscle strength was measured with a wrist dynamometer. Muscle function was examined using the tests of the Short Physical Performance Battery (SPPB). BMD at the neck and proximal femur as a whole and at the lumbar spine was measured by dual energy X-ray absorptiometry.For comparative analysis, the patients were divided into three groups (EWGSOP, 2010). Group 1 included 31 patients without sarcopenia; Group 2 consisted of 21 patients with presarcopenia; and Group 3 comprised 27 patients with sarcopenia.Results and discussion. Osteopenic syndrome was diagnosed in 34 (43%) patients: osteopenia and osteoporosis in 31 (39%) and 3 (4%) patients, respectively. Normal BMD values were observed in 45 (57%) men. The prevalence of osteopenic syndrome was significantly higher in the patients with sarcopenia than in those with presarcopenia (p=0.050) and was comparable to that in men without sarcopenia (p>0.050). BMD at the neck and proximal femur as a whole was significantly lower in the patients with sarcopenia than in those without sarcopenia or with presarcopenia (p<0.050). There was a direct correlation between BMD and the characteristics of muscle mass and muscle strength. Regression analysis showed that the total skeletal muscle area at the level of LIII had a significant direct impact on BMD at the neck and proximal femur as a whole, and the reverse – walking speed.Conclusion. The relationship between the characteristics of the muscular apparatus and BMD requires further investigation.

“Do you understand (me)?” negotiating mutual understanding by using gaze and environmentally coupled gestures between two deaf signing participants
Authors: Sivunen Nina , Tapio Elina 
Published: September 2020

Abstract
In this paper we explore the use of multimodal and multilingual semiotic resources in interactions between two deaf signing participants, a researcher and an asylum seeker. The focus is on the use of gaze and environmentally coupled gestures. Drawing on multimodal analysis and linguistic ethnography, we demonstrate how gaze and environmentally coupled gestures are effective semiotic resources for reaching mutual understanding. The study provides insight into the challenges and opportunities (deaf) asylum seekers, researchers, and employees of reception centres or the state may encounter because of the asymmetrical language competencies. Our concern is that such asymmetrical situations may be created and maintained by ignoring visual and embodied resources in interaction and, in the case of deaf asylum seekers, by unrealistic expectations towards conventionalized forms of international sign.
Free-edge effects of corrugated laminates
Authors: Filipovic Daniel T. , Kress Gerald R. 
Published: September 2020

Abstract
Due to their high numerical efficiency, homogenization models are often employed in the analysis of corrugated laminates. They are usually derived assuming periodic behavior in the corrugated direction and generalized plane strain in the out-of-plane direction, which corresponds to the assumption of infinite dimensions of the structure. As a consequence, any influences of edge effects are not mapped, although they can have a significant impact on the mechanical behavior of a given structure. The objective of this manuscript is to investigate the influence of boundary conditions - a combination of free-edges and clamping - on the structural stiffness of corrugated laminates. A total of six load cases are investigated which correspond to the line loads considered in the classical theory of laminated plates. The results of this parameter study allow the identification of several critical loading situations, where free edges can significantly alter structural stiffness. The given investigations hence contribute to the investigation of the validity range of homogenization models.
Extra, Extra, Reddit All About it: What Reddit can Teach us About Local Politics
Authors: Lê Adam , Farris Emily M. , Sumner Jane L. , Warmka Josephine M. 
Published: September 2020

Abstract
Although local government is a rich, important arena for understanding politics, local politics presents a few challenges for understanding and participating in it. To better explore comparative urban politics, we turn to reddit, a social media, news, and discussion platform. We ask if city subreddits are places of discussion of local politics and what can we learn about the salience of local topics, and about local politics, from the content of these subreddits. Using visualization and text analysis, we find that city subreddits are indeed forums for political discussion, finding that approximately a quarter of the topics on city subreddits are political in nature. We observe that people discuss matters including, but not limited to, taxation, policing and crime, homelessness, and education. We conclude with areas for future study, including, most prominently, the rise of nationalized local politics, such as minimum wage increases and body cameras, increasingly discussed and organized on the national stage.

Published: September 2020

Abstract
In this study, we describe the anion recognition ability of isatin-3-thiosemicarbazone 2, which contains two different anion recognition units i.e. isatin NH and the thiourea moiety. Both have the ability to act as proton donors. Most importantly, a significant colour change of 2 was observed (from light yellow to reddish orange) in organic medium only after the addition of the F– anion. No such colour change could be observed for any other anions including Cl–, Br–, I–,

The effect of M (M = Ce, Zr, Ce–Zr) on rolling microstructure and mechanical properties of FH40
Authors: Xianghai Meng , Mengxing Li , Meng Wang , Zhe Wang , Yungang Li 
Published: September 2020

AbstractCe, Zr and Ce–Zr composite experimentl steel were prepared by vacuum induction furnace and 550 twin-roll reversible rolling mill. Optical microscope (OM), scanning electronic microscopy (SEM) and energy dispersive spectrometer (EDS) were used to observe the rolling microstructure of the experimental steel. The mechanical properties of the experimental steel were tested and analyzed. The effect of cerium zirconium oxide inclusions on nucleation, tensile and impact fracture mechanism of intragranular acicular ferrite (IAF) was investigated. The results show that the rolling microstructure of steel containing 0.0052% Ce and the steel under composite treatment containing 0.0053% Ce and 0.0055% Zr is refined. IAF generation can be induced by Al–Ce–O inclusion of the size of 4 µm or induced by Al–Ce–Zr–O + MnS inclusion of the size of 3 µm. The yield strength and tensile strength of the steel treated by Ce–Zr are 428 and 590 MPa, respectively, the elongation is 23.55%, the longitudinal impact energy at −60°C is 189 J, which are 31, 45, 46 J and 6.25%, respectively, higher than those of the matrix steel. The dimple of the experimental steel at the fracture surface is larger and deeper than that of the matrix steel. The small inclusions in uniform distribution contribute to the high tensile strength of the experimental steel.

Published: September 2020

Abstract
The work has outlined the Fabry Perot laser properties with high pump lasers for upgrading fiber optic transceiver systems. The physical structures of the light source are taken into account such as active layer length and active layer width. High pump laser is used for providing strength to the signal through the transmission/reception stages. Peak and minimum signal power levels are measured in the spectral frequency domain and time domain. Signal amplitude level margin is also measured with the optimum physical parameters of the light source. The optimum operation system performance efficiency is achieved with an active layer length of 0.06 cm, and active layer width suitable is 1.5 × 10−4 cm.
The influence of field size, goal size and number of players on the average number of goals scored per game in variants of football and hockey: the Pi-theorem applied to team sports
Authors: Blondeau Julien 
Published: September 2020

Abstract
In this paper, we investigate the correlation between the main physical characteristics of eight variants of football and hockey (such as field size, goal size, player velocity, ball velocity, player density, and game duration) and the resulting average numbers of goals scored per game. To do so, the Pi-theorem in physics is extended to sport science and a non-dimensional parameter of interest is defined. It is based on the ratio between the duration of the game and the order of magnitude of the time needed to cross the midfield, which depends on the average velocity of the ball and the players, the player density and the size of the goals. An excellent correlation is found between the proposed parameter and the average number of goals scored per game during recent international competitions. Using the derived correlation, the effect of any modification of the main characteristics of football and hockey (and their variants) on the scoring pace can be assessed. For instance, it can be predicted that decreasing the length of football fields by 20 m would raise the average number of goals scored to 3.6 (±0.6) per game, versus the 2.6 goals scored during the most recent men’s World Cup.

Comprehensive evaluation of the industrial processing effects on the fiber properties of the pulps from wood residues
Authors: Chen Yuan , Shen Kuizhong , Li Gaiyun 
Published: September 2020

Abstract
Wood processing residue, as an essential forest resource, is underestimated in the industrial applications. With the development of pulping technology, fiber quality and cost control have become the important prospects. It is very crucial to investigate the influencing factors of pulping, designed to reveal the relationship between fiber separation and physical performances. In this study, a range of effect factors of large-scale pulping process, including wood species, pretreatment, mechanical conditions, and post-bleaching treatment, were comprehensively investigated. The results illustrated that the industrial pulping process affected the dimensions of the fibers, their surface morphology, chemical structure, and thermal stability. The separated positions of the fibers were determined collectively by the mechanical temperature, time, and wood species. In addition, mild bleaching could effectively increase the crystallinity index, accessibility of the hydroxyl groups, and water retention values. However, it exerted a negative influence on the thermal stability. Further, chemical-assisted-refinement can replace higher temperature and prolonged ones to obtain pulp fibers with high quality while consuming less energy. Improved knowledge of how the industrial affects the fiber separation of a wood matrix and pulp quality is required as a basis for the development of the pulp and paper industry.
The Invisible and the Hidden within the Phenomenological Situation of Appearing
Authors: Nitsche Martin 
Published: September 2020

AbstractThis study focuses on various phenomenological conceptions of the invisible in order to consider to what extent and in what way they involve moments of hiddenness. The relationship among phenomenality, invisibility, and hiddenness is examined in the works of Husserl, Heidegger, Henry, and Merleau-Ponty. The study explains why phenomenologists prefer speaking about the invisible over a discourse of the hidden. It shows that the phenomenological method does not display the invisibility as a limit of experience but rather as a dynamic component of relational nature of any experience, including the religious one. Special attention is paid to topological moments of the relationship between the visible and the invisible.
Electrochemical flow systems enable renewable energy industrial chain of CO2 reduction
Authors: Hung Sung-Fu 
Published: September 2020

Abstract
The development of a comprehensive renewable energy industrial chain becomes urgent since renewable energy will soon dominate the power generation. Among the industries, carbon dioxide reduction reaction (CO2RR), which uses energy to convert carbon dioxide into high-value products and reduce CO2 in the atmosphere, is regarded as a promising and potential industrial application. The conventional H-type reactor shows limited catalytic activity toward CO2RR, leading to the incompatible combination with the massive renewable energy. The flow systems – flow-cell reactor and the membrane electrode assemblies – show the promising selectivity and activities of CO2RR products, meeting the criteria for industrial mass production. In this Perspective, I start by comparing the market price and annual global production of major CO2RR products with the necessary costs using technoeconomic analysis for industrial utilization. Subsequently, I systematically summarize the catalytic performances of the same copper catalyst in these reactors for CO2RR and discuss the possibility of industrialization. Owing to the distinctive catalytic behaviors in flow systems, I finally present prospects to investigate the catalytic mechanisms by developing various in-situ techniques in these flow systems to speed up the renewable energy industry.
Analytical mathematical schemes: Circular rod grounded via transverse Poisson’s effect and extensive wave propagation on the surface of water
Authors: Ali Asghar , Seadawy Aly R. , Baleanu Dumitru 
Published: September 2020

AbstractThis article scrutinizes the efficacy of analytical mathematical schemes, improved simple equation and exp(-\text{&#x03A8;}(\xi ))-expansion techniques for solving the well-known nonlinear partial differential equations. A longitudinal wave model is used for the description of the dispersion in the circular rod grounded via transverse Poisson’s effect; similarly, the Boussinesq equation is used for extensive wave propagation on the surface of water. Many other such types of equations are also solved with these techniques. Hence, our methods appear easier and faster via symbolic computation.
Islands and Insularity: Between Law, Geography, and Fiction
Authors: Nicolini Matteo , Perrin Thomas 
Published: September 2020

Abstract
Within the cross-disciplinary research on “Law, Changes and Technology,” this essay introduces the focus on “Islands and insularity: between law, geography, and fiction.” The intriguing and enthralling topic of “Island-ness” places emphasis on the manifold intersections between law, geographic studies, political power, and the humanities. These intersections reflect several issues, such as territorial localisation, environmental crises, colonial imaginaries, as well as the insular societal contexts in which they are imbricated. The focus delivers both a synthetic view of these questions and opens up further perspectives for reflection. The contributions engage various topics and adopt different approaches. Beyond this richness of inputs, the essays reveal some common characteristics of islands and insularity as objects and subjects of human imagination, social organisation, and scientific reflection. In particular, two main issues of islands and insularity can be identified, i.e. dialectics and metaphor.
The Island Metaphor in Literature and Law
Authors: Carpi Daniela 
Published: September 2020

Abstract
The island embodies a new and subversive geopolitical area. All modern juridical systems are the result of a catastrophe emerging from a state of exception: those who reach an island are in fact survivors of a wreckage, be it physical, spiritual, or cultural. These assertions are the basis for the creation of literary islands, themselves the result of a wreckage, exiles, of a separation from a civilization with its own juridical systems, a disruption of a known system, of a catastrophe, whether physical, moral, political or social. The creation of an island invites a re-examination of the old relationships concerning the juridical, the political, and the theological.
Between Islands: Colonial Legacies and Cultural Imaginaries
Authors: Bottomley Anne 
Published: September 2020

Abstract
This paper explores one aspect of the geo-cultural axis constructing the “between” of England as island-metropole and the colonised islands of the Antillean archipelago: that of the crucial significance of the figuration of “island” in the colonial cultural imaginary of the early modern period. It is suggested that the development of “island” as key topographical trope, signifying sea power as opposed to continental imperialism, was a crucial means through which the metropolitan English curated an image of how colonial expansionism might be given meaning, and be experienced, in such a way as to enhance and enrich, rather than overwhelm and impoverish, England as “small island.” Using material drawn from seventeenth- and eighteenth-century literature, the paper traces the emergence of, first, England imaged as island garden-paradise, and then, second, the transposition and translation of “garden-paradise” islands into the tropics. This is framed by two images: the first the late seventeenth-century Paston Treasure, and the second a late eighteenth-century portrait of two young women by David Martin. The first is used to illustrate the need to order and curate images of, and in response to, the ‘colonial’ as an experience of encounter and engagement with “Other” through processes of legitimated and authorised subjectification. The second is deployed to illustrate the extent to which the “insular” English cultural imaginary achieved and sustained an account of the beneficial-colonial overseas project and marginalised, to the point of suppression, the violence of the actual-colonial in/on remote “(small) islands.” The portrait of the two women is then used to project forward in time in order to make visible the continuing strength of the colonial legacy of paradise-islands in the contemporary English cultural imaginary: in particular, in the exotic out-of-world and timeless imagery deployed in tourist brochures. As a final coda, the paper ends with referencing the potential of an-other “between islands”: that of a complex network of inter-Antillean creolisation interrupting and challenging the legacy of the linear and centrifugal metropole-(post-)colonial island axis.
Inheriting the Right of Return
Authors: Tadros Victor 
Published: September 2020

AbstractThis Article assesses one kind of argument for an intergenerational right of return in the context of the Israel/Palestine conflict. The question is whether descendants of those who were made refugees in the 1948 War can acquire occupancy rights from their parents through inheritance and bequest over territory that they have never lived on. Standard arguments for their inheriting such rights fail for a range of reasons. However, a less familiar argument for inheritance or bequest succeeds—descendants can acquire such rights because their parents have an interest in their being able to live the kind of life that, due to the violation of their rights, they were deprived of.
