THE IMPORTANCE OF SENSORY-MOTOR INTEGRATION IN EVERYDAY LIFE
Authors: Barros Vanessa Novaes
Published: November 2018

Integration of the central nervous system is essential for the proper motor response produced by the body. A good example of such integration is an everyday situation of a child playing in the garden barefoot until it steps on a piercing-cutting object. In this situation where the child is in the upright position two responses are expected: 1 – hip and knee flexion of the lower member that touched the object to avoid noxious stimulus. 2- Increase of the extension muscle tonus of the contralateral lower members in order to compensate the imbalance provoked by injured foot flexion.

In the modern world, the task of rapid delivery of goods and passengers between cities and countries is an urgent task. The "atmospheric" transport system is proposed as an alternative to the Hyperloop vacuum system in the form of an air cushion vehicle moving at a speed of 500 km / h over an overpass with an arch cover. Structurally, the device is designed as a cargo option for the rapid delivery of sea containers, and in the passenger version. The design of the device is simplified, and the risks associated with depressurization in a vacuum environment are excluded. The proposed transport is environmentally friendly and not dependent on the weather conditions of the environment. Methods are described that allow to determine the characteristics of air cushions, the parameters of the vehicle's movement along a curved path, as well as traction and energy indicators. Calculations are made on a concrete example.

The determination of the deformation parameters for high-speed extraction of axisymmetric thin-film blanks that ensure the shaping of parts without distortion of the shape of the relief and destruction of metal by the method of pneumatic impact punching is performed. On the basis of the conducted researches the technological possibilities of manufacturing of quality axisymmetric thin-walled details by the method of pneumatic impact punching are established. The conditions for the stability of the workpiece when forming the axisymmetric elements of a non-spherical shape are similar to the conditions for the stability of the workpiece during the shaping of spherical elements, and the results can be extended to the drawing of elliptical, shallow conical and other similar parts. Pneumatic impact punching allows you to pull dome-shaped parts without the use of hanging thresholds, two-transversal stamping and other special techniques with a relative billet thickness of two to four times less than allowed when drawing a punch.

Published: November 2018

The volume of nanostructures that are realized under the action of a number of ions (boron, nitrogen, zirconium, hafnium) is determined using the example of studying the influence of the fraction of components in a solid alloy containing Al2O3 and TiC at their different ratio of the fraction of components. Conditions (component ratios) are obtained for which the minimum grain sizes are realized, i.e., the hard alloy surface has the best physical-mechanical characteristics at 50Al2O3 and 50TiC. It is shown that when processing pure Al2O3 and TiC, it is also possible to obtain rather low grain size values. At the ratios of components 20-80 and 80-20, larger grain sizes are realized than in the previous cases. Nonequilibrium states can also be used after studying the physical and mechanical characteristics of hard alloys. It is shown that under the action of light ions (nitrogen), the temperature stresses do not reach the necessary values for the formation of nanostructures, and under the action of heavy ions (hafnium) there is a high probability of realization of nanostructures at an energy of 20 keV and insignificant under the action of ions with an energy of 200 eV.
Estimation of the Gruneisen parameter and an explicit measure of anharmonicity of dodecaborides
Authors: Fedyshyn Y. , Vadets D. , Garashchenko O. , Romanov O. , Fedyshyn T.
Published: November 2018

In previous works on the ratio   (θД – the characteristic temperature of Debye, was calculated according to the Lindemann formula; V – molar volume of hypothetical lattice atoms; γ is the Gruneisen parameter) for the group of dodecaborides (TbB12, DyB12, HoB12, ErB12, TuB12, LaB12, UB12) the average value of γ = 1.3 was determined. However, due to the ambiguity of the coefficient of proportionality in the Lindemann formula by definition θD, the authors selected an independent high-temperature X-ray method for determining the dependence θr (T). Taking into account the immutability of the structure and type of interatomic connection in the temperature interval of the search (293–973 K), the authors evaluated the value and temperature dependence of γ (T) of each dodecaboride separately. The results of the search showed that the value of γ for each given dodecaboride is different, but practically independent from temperature. For some dodecaborides, the parameter γ is about 2–3 units, and for others it is overestimated. The values of γ made it possible to estimate the magnitude of the implicit γβ and the explicit  parts of the universal measure of anharmonicity of dodecaborides , where β – real coefficient of volumetric expansion of the crystalline lattice. Because    (n – dimensionless coefficient of proportionality), then the temperature change n(T) is also determined.

Authors: Shvedyuk D. , Pasichnyi V. , Moroz O. , Heredchuk A.
Published: November 2018

The article is devoted to the influence of protease of microbiological origin on the autolysis process in broiler chicken meat. Protease made by Aspergillus fungi was chosen as an enzym. According to the experiment plan, 5 samples were made, including a control sample, in which autolytic processes were performed without the addition of an enzyme. The experimental group (samples I–IV) included samples with 30, 50, 70 and 90 mg of the added enzyme solution, respectively, per 100 g of basic meat raw material. After introduction of the enzyme and parallel fixation of the studied control parameters before maturation, the samples were stored at 4–6 °C for 2 days. The selected physicochemical parameters were studied in all samples after 1 and 2 days of storage. Among the parameters studied, the following were selected: pH, water-holding capacity (WHC), water binding capacity (WBC), fat binding capacity (FBC), moisture content, and optical density by measuring of soluble and water-soluble proteins volume. Examenated transition of proteins from salt- to water-soluble experimental group also as their overall solubility is noticeably higher than in the control sample. Among the functional and technological characteristics, these samples have shown a high pH and WHC levels. The WBC, FBC and total water content show a slight increase. The values of the studied parameters among the samples I–IV have not shown a noticeable difference. For research minced meat at 48 hours of maturation compared with the control, the increase of WHC was accordingly from 16.4 to 18.4%, the value of the university increased by 9.1–19.1%, and FBC by 1.1–5.9%. At the same time, the change in the proportion of salt and algae protein substances of minced meat according to the optical density for 48 hours of maturation was equalized with the control and the variation of this index fluctuated within 1–2 units. A literature and studies sources review have shown the effectiveness of microbial-derived protease enhancement under the action of protease ASP on the functional-technological indices of white meat of broiler chickens. It has been determined that when injecting into broth from chicken broiler meat, ASP proteases in an amount of 30 to 90 mg per 100 g of raw materials, an increase in the thermal stability indices for FBC by 1.1–5.9%, in higher education institutions by 9.1–19.1%, which makes it possible to effectively model the increase in the functional and technological characteristics of minced meat from the amount of enzyme addition and maturation time.

Studies have shown that the tested material can also act as a component of composite pellets. The quality parameters of such pellets can be determined with the composite calculator that is described in this article. The article also describes the technical aspects of the pellet production line, which should be applied to produce good-quality pellets from the tested types of biomass.
Influence of fish collagen on viscoelastic properties and sol-gel phase transition of chitosan solutions
Authors: Ryl Anna , Owczarz Piotr
Published: November 2018

The thermosensitive hydrogels are widely used in tissue engineering due to their non-invasive application. Special interest of researchers, due to the specific characteristics of both materials, is aimed at composites of natural origin obtained from chitosan hydrogels combined with collagen. The mechanical properties of the thermosensitive chitosan-fish collagen hydrogels and the sol-gel phase transition parameters were determined by the rotational rheometry measurement techniques. Based on comparison of the obtained storage modulus G' curves, it was found that the addition of collagen negatively affects the mechanical properties of composite scaffolds. The addition of this protein substance decreases their elasticity. Only the smallest concentration (0.25g collagen/1 g chitosan) of collagen improves the mechanical properties of composite hydrogels, from 56 kPa to 61 kPa. Conducted non-isothermal studies allowed to conclude that the addition of collagen causes an increasing temperature of sol-gel phase transition. However, the observed changes are not a monotone function of the biopolymer concentration.

Published: November 2018

Synthetic food dyes (E102, E104, E110, E122, E124, E132, E133) were concentrated by solid phase extraction on aminopropyl modified silica with aqueous sodium hydroxide or selected amines as eluents. Ponceau 4R (E124) was used as the model dye in the studies of the elution step. The recoveries of E124 differed depending on the eluent and ranged from 76% (AMP) to over 90% (TEA, imidazole, NaOH). Diluted aqueous triethanolamine (TEA) was found to be a suitable eluent for E124 but other dyes were eluted more effectively with NaOH. The solid extraction process was combined with UV/VIS spectroscopy to quantify synthetic dyes in drinks and OTC pharmaceutical tablets. The SPE-UV/VIS spectroscopic method was validated in terms of linearity, accuracy (recovery of dyes from spiked preparations), precision (repeatability, intermediate precision) and limits of detection/quantification. The method was found sufficiently fast, easy and reliable for the routine control of dyes in these types of products.

Comparison of Measurement-Based Methodologies to Apportion Secondary Organic Carbon (SOC) in PM2.5: A Review of Recent Studies
Authors: Srivastava Deepchandra , Favez Olivier , Perraudin Emilie , Villenave Eric , Albinet Alexandre
Published: November 2018

Secondary organic aerosol (SOA) is known to account for a major fraction of airborne particulate matter, with significant impacts on air quality and climate at the global scale. Despite the substantial amount of research studies achieved during these last decades, the source apportionment of the SOA fraction remains difficult due to the complexity of the physicochemical processes involved. The selection and use of appropriate approaches are a major challenge for the atmospheric science community. Several methodologies are nowadays available to perform quantitative and/or predictive assessments of the SOA amount and composition. This review summarizes the current knowledge on the most commonly used approaches to evaluate secondary organic carbon (SOC) contents: elemental carbon (EC) tracer method, chemical mass balance (CMB), SOA tracer method, radiocarbon (14C) measurement and positive matrix factorization (PMF). The principles, limitations, challenges and good practices of each of these methodologies are discussed in the present article. Based on a comprehensive—although not exhaustive—review of research papers published during the last decade (2006–2016), SOC estimates obtained using these methodologies are also summarized for different regions across the world. Conclusions of some studies which are directly comparing the performances of different methodologies are then specifically discussed. An overall picture of SOC contributions and concentrations obtained worldwide for urban sites under similar conditions (i.e., geographical and seasonal ones) is also proposed here. Finally, further needs to improve SOC apportionment methodologies are also identified and discussed.

HSPHZZ was covalently immobilized on Immobead 150 (ImmHSPHZZ). ImmHSPHZZ (obtained with 5–30 mg of protein per gram of support) catalyzed the hydrolysis of HSP to 2,5-DHP. At a protein loading of 15 mg g−1, ImmHSPHZZ converted 93.6% of HSP to 2,5-DHP in 6 h. The activity of ImmHSPHZZ was compared with that of free HSPHZZ under various conditions, including pH, temperature, enzyme concentration, substrate concentration and stability over time, and kinetic parameters were measured. The results showed that ImmHSPHZZ performed better over wider ranges of pH and temperature when compared with that of HSPHZZ. The optimal concentrations of ImmHSPHZZ and substrate were 30 mg L−1 and 0.75 mM, respectively. Under optimal conditions, 94.5 mg L−1 of 2,5-DHP was produced after 30 min with 85.4% conversion. After 8 reaction cycles and 6 days of storage, 51.3% and 75.0% of the initial enzyme activity remained, respectively. The results provide a framework for development of commercially suitable immobilized enzymes that produce 2,5-DHP.
Is a Meal without Wine Good for Health?
Authors: Rifler Jean-Pierre
Published: November 2018

Hippocrates, the father of medicine, had said: “Wine is a thing wonderfully appropriate to man if, in health as in disease, it is administered with appropriate and just measure according to the individual constitution.” Wine has always accompanied humanity, for religion or for health. Christians and Jews need wine for the liturgy. For Plato, wine was an indispensable element in society and the most important in the symposium. In this second part of the banquet, mixed with water, the wine gave the word. If the French paradox made a lot of ink flow; it was the wine that was originally responsible for it. Many researchers have tried to study alcohol and polyphenols in wine, in order to solve the mystery. Beyond its cardiovascular effects, there are also effects on longevity, metabolism, cancer prevention, and neuroprotection, and the list goes on. The purpose of this work is to make an analysis of the current knowledge on the subject. Indeed, if the paradigm of antioxidants is seductive, it is perhaps by their prooxidant effect that the polyphenols act, by an epigenetic process mediated by nrf2. Wine is a preserve of antioxidants for the winter and it is by this property that the wine acts, in an alcoholic solution. A wine without alcohol is pure heresy. Wine is the elixir that by design, over millennials, has acted as a pharmacopeia that enabled man to heal and prosper on the planet. From Alvise Cornaro to Serge Renaud, nutrition was the key to health and longevity, whether the Cretan or Okinawa diet, it is the small dose of alcohol (wine or sake) that allows the bioavailability of polyphenols. Moderate drinking gives a protection for diseases and a longevity potential. In conclusion, let us drink fewer, but drink better, to live older.

A strong earthquake of magnitude M w 6.8 struck Western Greece on 25 October 2018 with an epicenter at 37.515 ∘ N 20.564 ∘ E. It was preceded by an anomalous geolectric signal that was recorded on 2 October 2018 at a measuring station 70 km away from the epicenter. Upon analyzing this signal in natural time, we find that it conforms to the conditions suggested for its identification as precursory Seismic Electric Signal (SES) activity. Notably, the observed lead time of 23 days lies within the range of values that has been very recently identified as being statistically significant for the precursory variations of the electric field of the Earth. Moreover, the analysis in natural time of the seismicity subsequent to the SES activity in the area candidate to suffer this strong earthquake reveals that the criticality conditions were obeyed early in the morning of 18 October 2018, i.e., almost a week before the strong earthquake occurrence, in agreement with earlier findings. Finally, when employing the recent method of nowcasting earthquakes, which is based on natural time, we find an earthquake potential score around 80%.
The Role of Complex Analysis in Modelling Economic Growth

Development and growth are complex and tumultuous processes. Modern economic growth theories identify some key determinants of economic growth. However, the relative importance of the determinants remains unknown, and additional variables may help clarify the directions and dimensions of the interactions. The novel stream of literature on economic complexity goes beyond aggregate measures of productive inputs and considers instead a more granular and structural view of the productive possibilities of countries, i.e., their capabilities. Different endowments of capabilities are crucial ingredients in explaining differences in economic performances. In this paper we employ economic fitness, a measure of productive capabilities obtained through complex network techniques. Focusing on the combined roles of fitness and some more traditional drivers of growth—GDP per capita, capital intensity, employment ratio, life expectancy, human capital and total factor productivity—we build a bridge between economic growth theories and the economic complexity literature. Our findings show that fitness plays a crucial role in fostering economic growth and, when it is included in the analysis, can be either complementary to traditional drivers of growth or can completely overshadow them. Notably, for the most complex countries, which have the most diversified export baskets and the largest endowments of capabilities, fitness is complementary to the chosen growth determinants in enhancing economic growth. The empirical findings are in agreement with neoclassical and endogenous growth theories. By contrast, for countries with intermediate and low capability levels, fitness emerges as the key growth driver. This suggests that economic models should account for capabilities; in fact, describing the technological possibilities of countries solely in terms of their production functions may lead to a misinterpretation of the roles of factors.
Simulation Study of Power Management for a Highly Reliable Distribution System using a Triple Active Bridge Converter in a DC Microgrid
Authors: Yu Yue , Wada Keiji
Published: November 2018

Owing to the acute energy shortage issue and the increasing energy demands of information and communication technology systems worldwide, the development of a DC microgrid that can utilize renewable energy sources, such as wind and photovoltaic power, has been accelerated. Therefore, power management for DC microgrid distributed systems is promoted to achieve high reliability and efficiency in power distribution systems. For industry and power transmission applications such as data centers, power management with the help of DC converters is highly recommended. In this paper, we propose a prototype of a power distribution system with a triple active bridge (TAB) converter for data centers in the DC microgrid. Moreover, we introduce a power management approach for a distribution system using the TAB converter. Finally, we perform simulations of the proposed configuration to verify the controllability of the circuit performance and the high reliability of the system.

Published: November 2018

A microbial electrolysis cell (MEC) consumes the chemical energy of organic material producing, in turn, hydrogen. This study presents a new hybrid MEC design with improved performance. An external TiO2 nanotube (TNT) array photoanode, fabricated by anodization of Ti foil, supplies photogenerated electrons to the MEC electrical circuit, significantly improving overall performance. The photogenerated electrons help to reduce electron depletion of the bioanode, and improve the proton reduction reaction at the cathode. Under simulated AM 1.5 illumination (100 mW cm−2) the 28 mL hybrid MEC exhibits a H2 evolution rate of 1434.268 ± 114.174 mmol m−3 h−1, a current density of 0.371 ± 0.000 mA cm−2 and power density of 1415.311 ± 23.937 mW m−2, that are respectively 30.76%, 34.4%, and 26.0% higher than a MEC under dark condition.
Modular Proteoglycan Perlecan/HSPG2: Mutations, Phenotypes, and Functions
Authors: Martinez Jerahme R. , Dhawan Akash , Farach-Carson Mary C.
Published: November 2018

Heparan sulfate proteoglycan 2 (HSPG2) is an essential, highly conserved gene whose expression influences many developmental processes including the formation of the heart and brain. The gene is widely expressed throughout the musculoskeletal system including cartilage, bone marrow and skeletal muscle. The HSPG2 gene product, perlecan is a multifunctional proteoglycan that preserves the integrity of extracellular matrices, patrols tissue borders, and controls various signaling pathways affecting cellular phenotype. Given HSPG2’s expression pattern and its role in so many fundamental processes, it is not surprising that relatively few gene mutations have been identified in viable organisms. Mutations to the perlecan gene are rare, with effects ranging from a relatively mild condition to a more severe and perinatally lethal form. This review will summarize the important studies characterizing mutations and variants of HSPG2 and discuss how these genomic modifications affect expression, function and phenotype. Additionally, this review will describe the clinical findings of reported HSPG2 mutations and their observed phenotypes. Finally, the evolutionary aspects that link gene integrity to function are discussed, including key findings from both in vivo animal studies and in vitro systems. We also hope to facilitate discussion about perlecan/HSPG2 and its role in normal physiology, to explain how mutation can lead to pathology, and to point out how this information can suggest pathways for future mechanistic studies.

Multiple myeloma is an invariably fatal cancer of plasma cells. Despite tremendous advances in treatment, this malignancy remains incurable in most individuals. We postulate that strategies aimed at prevention have the potential to be more effective in preventing myeloma-related death than additional pharmaceutical strategies aimed at treating advanced disease. Here, we present a rationale for the development of prevention therapy and highlight potential target areas of study.
