Authors: Tsygankov N S , Petrunina A E , Moskalev A K , Valkova Y E 
Published: December 2020

Abstract
At the initial stage of economy innovative potential formation, the leading role belongs to small venture firms that provide market development of the intellectual activity results. Support for small businesses of this type is usually provided through the development of a business incubators system initiated by regional authorities and implemented through targeted budget funding. In this regard, it is important for incubators to develop an indicators system for evaluating the effectiveness of budget allocations and private investment. The paper proposes a two-level system of business incubator functioning and develops a management structure that allows analyzing the current state of the organization and the results of its work using a mathematical model. The incubator activity is determined by the state of the system at the time of starting the next cycle of work, the state of the incubated companies at each stage of incubation (pre-incubation, incubation, post-incubation) and planned tasks, taking into account resource and technological limitations. The proposed model can be used in the development of methods for continuous deviations monitoring from the planned performance indicators of the organization with the ability to pinpoint the problem and respond to it. The advantage of the proposed model is that it can be scaled up to the level of the innovation structure of the region.

Authors: Ustinov A. , Zybina O. , Kruglov E. 
Published: December 2020

Abstract
The paper overviews the mechanism of fire-retardant action of intumescent coatings in relation to wooden structures. A comparative assessment of fire-retardant performance of various intumescent compositions, their effectiveness in relation to wood and materials based on it, has been carried out. For this, tests were carried out using the «ceramic tube» method and tests in the cellulosic fire mode. As a result of tests, it was shown that glass microspheres, kaolin, and water-soluble sulfonated graphene are significantly effective functional additives in the intumescent composition. The mechanism of their influence on fire retardant efficiency is considered. It has been shown that compositions containing sulfonated graphene provide a delay in heating in the surface layer of wooden sample, whereas classical intumescent compositions more effectively provide a delay in heating in the depth of the sample. Almost all of the considered compositions demonstrated satisfactory performance when tested by the «ceramic tube» method, thus these compositions allow to make the wood hardly flammable and hardly combustible.

Published: December 2020

Abstract
Current article is devoted to the application of computer-aided engineering technologies to the virtual testing of customized endoprostheses of large joints. The research is performed for a representative case, where the personalized prosthesis of the hip joint is used as a part of the process of treatment of osteosarcoma, as conventional systems are not applicable. The study is highly relevant due to the intensive development of personalized medicine allowing for the patients’ successful recovery and mobilization. However, since each of the customized implants is a unique part, a rapid, accurate and financially efficient methodology of performing the structural analysis of such components is required to avoid the real testing of each implant. The article describes the all steps of the structural simulation of the series of loading scenarios for the biomechanical system consisting of the pelvis and endoprosthesis. The process of preparing the finite element models of pelvic bones and components of the implant is also explained in detail. The stress-strain state of the pelvis and implant is investigated for a number of values of the pretension force of the screws. Based on the comparative analysis, a set of practical recommendations is formulated to reduce the stress in the bone tissue. The discussed steps are the elements of the methodology of the rapid finite element virtual testing of the customized implants that is currently developed by the research group.

Published: December 2020

Abstract
The paper is devoted to the development of a method for optimizing the tread pattern to push aside the water from the road contact patch. This technique works with ready-made tread patterns of any type. Today, the methodology under consideration is relevant, since it prevents the occurrence of one of the most common causes of road accidents - aquaplaning. Currently, it is impossible to eliminate the risk of such an effect. It can only be reduced by slowing down or ensuring a uniform load on all wheels, trying to drive through the puddle with all four wheels.

Abstract
The goal of this research was to determine the corrosion resistance of metal materials used in ECP constructions as well as to determine the degree of degradation of the metal properties of rubber compounds (RS-3, TER-10, AF-15) after exposure to a corrosive environment. In order to assess the impact of a corrosive environment on changes in the mechanical properties of rubber compounds used in ECP constructions, tests were carried out for rubber samples of the compounds RS-3 (TU 2512-028-46521402-2014), TER-10 (TU 2512-028-46521402-2014), AF-15 (TU 2512-028-46521402-2014) in their initial state and after testing in a corrosive environment in an autoclave. Tests on samples of structural metal materials (05Cr16Ni4, 40Cr13, 40Cr, 22MnAl, Nirezist) in an aqueous saline solution containing ions of chlorides. According to these tests at 240, 480 and 720-hour exposure in the autoclave, the steel 05Cr16Ni4 is passive in the given corrosive environment and has a corrosion rate of ≤ 0.01 mm / year. Tests of samples of four steels of grades 05Cr16Ni4, 40Cr13, 40XCr and 22MnAl in a solution of hydrochloric acid with pH = 0 over 6 hours at room temperature showed.

Published: December 2020

Abstract
Main reasons and wear mechanism of steam turbine blades have been examined. Efficient recovery method of steam turbine blades allowing to increase their service life and enhance greatly service life of power units have been suggested. Materials to deposit coating layers have also been selected and deposition technology have been developed. Structure, porosity, micro-hardness, adhesion strength, erosion resistance and heat resistance of deposited coating have been researched. Suggested method can be used both for deposition of a coating on new turbine blades and for recovery of worn surfaces without overhaul of a turbine due to applying of a mobile compact plasma unit of in-house design. Composition of the coating featuring meso-arranged structure during deposition process greatly increases most operational performances of the whole ‘coating – substrate’ system.
Drop-on-demand printing of edge-enhanced and conductive graphene twin-lines by coalescence regulation and multi-layers overwriting
Authors: Lian Hongcheng , Qi Lehua , Luo Jun , Zhang Ruirui 
Published: December 2020

Abstract
Fabrication of straight and highly conductive graphene lines, the cornerstones of high-performance graphene-based printed electronics, still faces considerable challenges. We have developed a convenient and effective way to print edge-enhanced highly conductive graphene twin-lines by coalescence regulation and multi-layers overwriting (CRMO), which enhances both outline accuracy and electrical conductivity. The overlapping traces and wavy edges were eliminated by droplets coalescence at the expense of introducing discrete footprints, which were transformed into continuous lines by multi-layers overwriting. We successfully fabricated the edge-enhanced graphene twin-line with an edge width of 72.33 ± 7.96 μm and a linear resistivity of 0.188 ± 0.160 kΩ μm−1, yielding the coinstantaneous enhancement of outline accuracy, printing efficiency, and electrical conductivity. Printed graphene twin-lines achieve one of the lowest relative linear resistivity reported so far and a conductivity of 359.88 S m−1. We attributed the highly concentrated and tightly interconnected graphene flakes at the edge to the synergetic effect of CRMO. Finally, we have demonstrated the feasibility of CRMO by printing graphene line resistors with excellent linearity and broad resistance ranges. Such findings establish relationships among the printing method, line morphologies, flakes distribution, and electrical conductivity. This work will be of great significance for the self-assembly of graphene-based functional materials and graphene-based printed electronics development.
Assessment of the force attenuation capability of 3D printed hip protector in simulated sideways fall
Authors: Yahaya S A , Ripin Z M , Ridzwan M I Z 
Published: December 2020

Abstract
An innovative 3D printed hip protector has been designed and tested to decrease the possibility of hip fracture in a sideways fall to a hard surface. The main design purpose was to create custom fit hip protector, reduce the manufacturing period and make the protector comfortable to wear. This work compares the new energy shunting 3D printed hip protector design with an existing energy absorbing hip protector. A drop tower mechanical test rig was designed and developed to simulate a sideways fall with sufficient impact energy to fracture an unprotected greater trochanter (GT). The test rig incorporates the actual geometry of a femur made from steel and uses a foam to simulate trochanteric soft tissue over the greater trochanter. Similar impact energy was used for the testing of each hip protector. The weight of the striker mass was maintained, and the height was adjusted to obtain an impact energy of 21–43J to produce femoral neck force of 3–9 kN. Results illustrate that the 3D hip protector compares favorably in attenuating impact force capable of causing hip fracture to a value below the fracture threshold of 3.472 kN. The influence of the 3D hip protector on peak transmitted forces to the vulnerable site of the greater trochanter is shown to be positive. It is anticipated that future protectors can be 3D printed after optimizations to end the bundling of same hip protector for different body geometry.
Simulation and experimental study on microstructure evolution of 5CrNiMoV steel during multi-directional non-isothermal forging
Authors: Hu Zhiqiang , Wang Kaikun , Yang Li 
Published: December 2020

Abstract
Microstructure evolution during the hot forming shows a significant impact on material’s mechanical properties. To explore the deformation characteristics of 5CrNiMoV steel, numerical simulation and microscopic phase-field simulation of the multi-direction forgings were carried out. The strain distribution at each pass was investigated and the evolution of temperature, effective strain, effective strain rate, and grain size was acquired. The hot forging trials were carried out and three typical regions of forgings were taken to study the microstructure evolution. Detailed microstructure characterizations showed that the constructed parent austenite grain size of the forging in typical regions was slightly larger than the simulation results due to the grain coarsening during the air cooling. There were large amounts of high angle grain boundaries (HAGBs) for the occurrence of complete dynamic recrystallization and many bulging grain boundaries showed that discontinuous dynamic recrystallization (DDRX) could be the governing mechanism of nucleation and growth of dynamic recrystallization (DRX). Besides, the hot deformation texture changed significantly during the non-isothermal forging and the texture component differed remarkably at different regions of the forging. The main hot deformation texture components were Cube {001}<100> and Goss{011}<100>.
Unbiased Approaches for Reviewing Entomology Literature: A Systematized Review
Authors: Oliveira Ana R S , Cohnstaedt Lee W , Cernicchiaro Natalia 
Published: December 2020

AbstractEvidence synthesis and knowledge translation are scientific methodological approaches used across different disciplines for combining results from individual studies, interpreting them based on the body of evidence and with the objective of supporting decision-making. Systematic, rapid, and scoping reviews have a direct application in human health and social care, but also in veterinary medicine, which are areas that can overlap with medical and veterinary entomology. As a scientific field, the objective of medical and veterinary entomology is to identify and quantify the role of insects as transmitters of important arthropod-borne pathogens, thus contributing to the study of human and veterinary issues of public health importance. The main objectives of this review are to introduce to entomologists the most common knowledge translation and synthesis methods described in the literature, to then review the use of systematic, rapid, and scoping reviews applied in the medical and veterinary entomology field, using a systematized review approach. We found 120 relevant articles in the literature addressing topics related to medical and veterinary entomology and using systematic reviews of the literature or other evidence synthesis methods, which is concurrent with the ongoing trend towards the use of these methodologies. The application of unbiased approaches to entomology in general, and to medical and veterinary entomology in particular, will strengthen science- and evidence-based conclusions to be used as a tool for informing policy, decisions, and interventions.
Point: Reconciling Epidemiology’s Aspirations and Capabilities
Authors: Savitz David A 
Published: December 2020

Abstract
Interpreting the results of epidemiologic studies calls for objectivity and rigorous scrutiny, acknowledging the limitations that temper the applicability of the findings to public health action. Current trends have posed new challenges to balancing goals of scientific objectivity and validity with public health applications. The ongoing tension between epidemiology’s aspirations and capability has several sources: the need to overpromise in research proposals, compromising methodological rigor because of public health importance, defending findings in the face of hostile critics, and appealing to core constituencies who have specific expectations from the research.

Abstract

Introduction
Alcoholism is a growing problem with increasing incidence on in women. The aim of our study was to evaluate drinking habits in women using Alcohol Use Disorders Identification Test (AUDIT), and to look for differences in relations to respondents’ demographic, behavioral, and medical characteristics.

Methods
This cross-sectional study included 327 adult women who did not visit a physician due to liver enzymes abnormalities or any other significant health issue. All subjects filled in a questionnaire consisting of socio-demographic survey and the AUDIT.

Results
The statistically significant influence of the respondents’ age on the answers to the AUDIT was observed in Q1-Q5, Q7, and Q8, and in alcohol use risk groups. It was observed that women with a university degree use alcohol more often, compared to those who have attended primary, or middle school. The effect of responders’ employment status demonstrated a statistically significant difference in response to Q3, Q5, Q7, and Q8, and in alcohol use risk groups. We found that marital status contributes to drinking patterns. We found statistically significant difference to the answers on Q1-Q3, Q5, Q7, and Q8. The effect of offspring on the answers on the AUDIT was analyzed and a statistically significant difference was noted in the answers to the Q1-Q3, Q5, Q7, Q8, and in alcohol use risk groups.

Conclusion
Alcohol use among women is commonly and severely overlooked. Our results showed younger women, the unemployed, those in domestic partnerships, single ones and those with no children deserve increased surveillance.
