Published: May 2020

Abstract
The article examines the screw modules of technological machines that feed materials under pressure and move loads in the vertical direction to various working bodies. The main disadvantage of these screw modules is low productivity due to the spiral movement of the material, with a significant deviation from the longitudinal axis of the screw module. The paper considers the possibility of increasing the operational performance of screw modules of technological machines by reducing the rotational component of the material movement. This goal is achieved by installing ribs on the inner surface of the module. The angle of ribs installation is determined by the kinematic and geometric parameters of the conveyor auger shaft and the properties of the supplied and moved loads. The results of theoretical studies show that correctly selected geometrical parameters of the ribs can increase the screw module productivity by 18 – 20%.
Optimization of costs of residual deficit regulation in production system
Authors: Mamonov V I , Milekhina O V 
Published: May 2020

Abstract
The article considers the production subsystem as an element of the technological chain of a production system of any structure. Improvement of business efficiency involves optimizing key integration processes and coordinating the interaction of subsystems and links in technological chains. Each subsystem participates in the production of final products and is both a consumer and a supplier of products. The influence of various factors on the production process, including random ones, is the cause of violations of the time standards for product movement, which is expressed in deviations of the actual timing of the launch and release of planned accounting units from the planned standards. The concepts are introduced: late start-up in the subsystem - input deficit, delay transfer to the time of planned start - up in a neighboring subsystem along the technological chain-residual deficit. The solution of the subsystem is analyzed taking into account the amount of deficit transmitted along the technological chain. The function of costs for regulating external instability is defined, which includes two parameters: the value of the input deficit and the value of the residual deficit. If there is a residual deficit, compensation for the cost of reserving a neighboring subsystem along the chain is carried out in accordance with the linear function of the penalty and should be sufficient to neutralize it in this subsystem. A solution to the problem was obtained and a policy for regulating the remaining deficit was formulated.
Study conclusion mechanisms in hybridization of neural and logic intelligent systems
Authors: Pishchukhin A M , Akhmedyanova G F 
Published: May 2020

Abstract
The paper investigates the integration problems neural networks sections allocated in accordance with the functions performed. As an initial example, we study two trained neural matrices, one of which performs the function of recognizing the position of the manipulator and its speed, and the second generates responses using the corresponding robot drives. In addition to training mechanisms based on the adjustment of transfer weights, the mechanisms based on the supply of excitation / inhibition waves from the edges of the neural network are also affected. At the same time, training is reduced to multiple forced guiding of the robot manipulator along the target path, during which the desired paths of beatings are automatically found using comparators. The matrices are trained separately and then joined using a standard signal generated by a special unit. The division of the neural network into two sections allows building the necessary logic between them. This hybridization significantly expands the range of tasks. As a test problem, the task of searching for a given part from a jointly located set of parts in general position was selected. At the same time, the control system finds a given part, rotates its predetermined model until a matching image is obtained, and thereby understanding how the part is located and how best to capture it occurs.

Published: May 2020

Abstract
This study of the process of chip formation and curling when cutting ductile materials supplements the work of well-known authors in this field. The relevance of theoretical and experimental research stems from determination of the design parameters of chip formation by the flat spiral shape. The study used tools and materials that closely resemble those used in machine repair shops. A distinctive feature of this study is the use of theoretical and experimental data to determine the conditions of chip breaking and to design chip-forming elements on the cutting face of a metal-cutting tool. The obtained results allowed theoretical calculation of the geometrical parameters of a metal-cutting tool in constrained cutting and determination of the areas of chip formation with a high bulk density.
Designing Hygienic and Energy Saving of Water Dispenser Machine

Published: May 2020

AbstractThe use of a dispenser at the office is not as frequent as at home, because it is only used during working hours or at certain times. The use of dispensers must be in accordance with established health standards, so the quality of water produced by the dispensers must also be hygienic and free of germs or bacteria. Generally, water dispensers are operated for 24 hours, meaning that the dispensers use up a lot of electrical energy. In addition, the use of dispensers must also comply with established health standards, so the quality of the water produced by the dispensers must also be hygienic and free of germs or bacteria. Meanwhile the quality of the water produced by the device cannot be monitored. To overcome this problem, a study was conducted by designing a hygienic and energy efficient water dispenser design by applying a forward scheduling approach. The design is carried out through several components, namely ultraviolet (UV), dispenser heaters, Arduino Uno sensors, DS18B20 sensors, HC SR-04 sensors, DC pumps, 2 relays, and RTCDS1307. The results of this study indicate that the dispenser heating system can work based on a set schedule by applying an advanced scheduling approach referring to the RTC DS1307 time reading. The UV lamp can be lit for 10 minutes to sterilize the main container of the dispenser with an estimated suppression of E. Coli bacteria about 87.5 colonies / minute. This system is able to suppress the growth of bacteria about 875 colonies for once lighting. This system can control the quality of water that is safe for consumption and saves electricity energy up to 79.87 kWh per month.

Published: May 2020

Abstract
To study the effect of phase on the microstructure and mechanical properties of nitride coatings, three films of TiN, TiAlN, and TiSiN were prepared on the surface of high-speed steel using hollow cathode assisted multi-arc ion plating technique. The XRD lines of the three films were analyzed and calculated by linear analysis. The element and phase of the film were observed and analyzed by x-ray Diffraction (XRD), Transmission Electron Microscope (TEM), energy dispersive x-ray analysis (EDS). The microstructure and film thickness of the coating were characterized by scanning electron microscopy (SEM). The surface roughness of the film was observed by Confocal laser scanning microscope (CLSM). The hardness, friction coefficient, and coating/substrate adhesion of the film were tested by the G200 nanometer hardness tester and CETR UNMT-1 surface micro-nano mechanical test system. We discovered two different reinforcement mechanisms. The high microscopic strain value (1.309 × 10−3) in the TiAlN film was related to the formation of Ti3AlN substitutional solid solution in the film formed a large lattice distortion,however, the coating/substrate adhesion (33.5 N) was lowered. The result of independent nucleation and growth of the Si3N4 phase in the TiSiN film refines the structure of the film, alleviating the increase of microscopic strain. At this time, the coating/substrate adhesion reaches the highest value of 40 N and the film surface roughness reaches the minimum value of 0.451 μm. The results also show that the TiSiN coating can obtain good coating/substrate adhesion without pre-plating.

Authors: Zare Chavoshy Homeira , Ghasemi Razieh 
Published: May 2020

AbstractIn this study, an optical platform based on fluorescent nanofiber was developed for detection of microRNA-21 as a biomarker of cancerous cells. The fluorescent polyacrylonitrile nanofiber was fabricated using electrospinning method. The surfaces of nanofiber were treated by NaOH to convert nitrile groups to carboxyl moieties. Activation of these carboxyl groups by EDC-sulfo NHS coupling agents was done and then the covalent bonding between COOH groups of nanofiber and –NH2groups of amino-probe was formed. The results of SEM, XRD, FTIR, and fluorescence microscopy confirmed that the process of fluorescent nanofiber synthesis was successfully performed. Hybridization of probe and microRNA-21 showed that the capture efficiency of this fluorescent nanofiber was 1 pmolμl−1and these nanofibers have the potential to be used as optical sensors for detection of microRNA-21.
Self-organized and self-assembled TiO2 nanosheets and nanobowls on TiO2 nanocavities by electrochemical anodization and their properties

Published: May 2020

Abstract
In this research work, we prepared for the first time TiO2 nanosheets and nanobowls assembled on an arrangement of TiO2 nanocavities, and studied their morphological, optical, and structural properties. The assembled nanostructures were synthesized by a fast two-step electrochemical anodization using fluorides and ethylene glycol. By Field Emission Scanning Electron Microscopy, we showed that these nanostructures have a morphology well organized and ordered with a homogeneous distribution. Also, other characteristics such as photoluminescence, reflectance spectra, band gap energy, and Raman spectra were studied and compared with the optical and structural properties of TiO2 nanotubes. We found that the time of anodization is a key parameter to control the final shape of the individual elements in the nanostructure. Our results show that when nanobowls or nanosheets are self-assembled on nanocavities the morphological, optical, and structural properties change significantly in comparison to TiO2 nanotubes. Furthermore, the emission was improved considerably and the band gap energy was modified to higher energy values. Likewise, the interference fringes are generated in the reflectance spectra by the length of the nanocavities and by the thickness of the nanobowls and the nanosheets. Finally, a reduction on the displaced the Eg(1) Raman mode was observed with decreasing of the length of the nanocavities.
Anticipated Alienation and Critical Social Work: Ex-Offenders’ Perspectives on Re-entry
Authors: Barak Adi , Stebbins Amy 
Published: May 2020

Abstract
The criminal justice system constrains social workers’ ability to practice critical social work. Given the increased rates of re-entry from prison into disenfranchised, minority communities in the USA, knowledge about re-entry should be made available to social workers wishing to assist those who suffer from extreme marginalisation and oppression during re-entry. In this qualitative research study, we interviewed American male halfway house residents (N = 21) in the lead-up to their release about their perspectives on returning to their communities of origin, settling into other communities and meeting individuals from outside of their immediate social networks. Our results demonstrate that research participants anticipated experiencing social alienation in all three domains. Our discussion contextualises these findings within two dimensions of critical social work: critical consciousness and critical social policy.
Labour market outcomes of different institutional regimes: evidence from the OECD countries
Authors: Le Hang , Wood Geoffrey , Yin Shuxing 
Published: May 2020

Abstract
The rise of populism has been widely ascribed, at least in part, to an inability of national systems to generate decent employment or, indeed, stem its decline. This article explores the basis and nature of variations in labour market outcomes of different institutional regimes. For this comparative institutional analysis, we build indexes of labour market outcomes in the OECD countries, measuring actual cross-country variations and encompassing a much wider range of evidence in terms of countries and time periods covered than previous studies. We show that in terms of job availability and wages, the liberal market economies (LMEs) have advantages, but once involuntary part-time employment and wage inequality are considered, labour market outcomes appear superior in the continental European countries and the Scandinavia social democracies. However, any advantages of the LMEs appear to be diminishing since the global financial crisis. Compared with other regimes, Southern European and transitional economies have lower level of job availability and wage rates but are comparable in other aspects of the labour market.
Is Fertility a Leading Economic Indicator?
Authors: Buckles Kasey , Hungerman Daniel , Lugauer Steven 
Published: May 2020

Abstract
Many papers show that aggregate fertility is pro-cyclical over the business cycle. Using data on more than 100 million births from 1988 to 2014, we show that for recent recessions in the United States, there is a large and rapid fall in the growth rate of conceptions several quarters prior to economic decline. This newly emerging pattern appears in the aggregate data, as well as within individual states and in many European countries. Our findings suggest that fertility behaviour is more forward looking and sensitive to changes in short-run expectations about the economy than previously thought.
The ‘Rights’ Way to Democratize the Science–Policy Interface in International Environmental Law? A Reply to Anna-Maria Hubert
Authors: Peel Jacqueline 
Published: May 2020

Abstract
Science is widely regarded as being necessary for effective international environmental decision-making and risk assessment processes. However, it is equally well recognized that uncertainties or the complexity of phenomena under study mean that science may only offer partial knowledge for environmental problems in many circumstances. ‘Democratization’ of science is often proposed as a solution to this dilemma. This may involve incorporating a wider spectrum of expert views and public inputs in risk assessments of new technologies, public participation in science through so-called ‘citizen science’ initiatives or the application of the precautionary principle. This reply reviews these approaches and contrasts them with another tantalizing possibility offered by Anna-Maria Hubert’s article; a human rights-based approach drawing on the ‘oft-neglected’ right to science. It assesses the extent to which a rights-based approach, utilizing the right to science, offers a way to bridge the gap between science and democracy in contested international environmental legal decision-making processes. While it concludes that there are important potential benefits to the application of the right to science in international environmental law, it is far from clear that it provides a panacea given the limitations on the right expressed in the international human rights instruments in which it is found, such as the International Covenant on Economic, Social and Cultural Rights. Instead, the right to science can be seen as placing another thumb on the scales – alongside the precautionary and participatory approaches – in favour of enabling broader, more democratically accountable decision-making in cases of uncertain science and contested environmental risks.

Published: May 2020

Abstract

Objectives
A whole-genome screen at sub-gene resolution was performed to identify candidate loci that contribute to enhanced or diminished ciprofloxacin susceptibility in Salmonella enterica serovar Typhi.

Methods
A pool of over 1 million transposon insertion mutants of an S. Typhi Ty2 derivative were grown in a sub-MIC concentration of ciprofloxacin, or without ciprofloxacin. Transposon-directed insertion site sequencing (TraDIS) identified relative differences between the mutants that grew following the ciprofloxacin treatment compared with the untreated mutant pool, thereby indicating which mutations contribute to gain or loss of ciprofloxacin susceptibility.

Results
Approximately 88% of the S. Typhi strain’s 4895 annotated genes were assayed, and at least 116 were identified as contributing to gain or loss of ciprofloxacin susceptibility. Many of the identified genes are known to influence susceptibility to ciprofloxacin, thereby providing method validation. Genes were identified that were not known previously to be involved in susceptibility, and some of these had no previously known phenotype. Susceptibility to ciprofloxacin was enhanced by insertion mutations in genes coding for efflux, other surface-associated functions, DNA repair and expression regulation, including phoP, barA and marA. Insertion mutations that diminished susceptibility were predominantly in genes coding for surface polysaccharide biosynthesis and regulatory genes, including slyA, emrR, envZ and cpxR.

Conclusions
A genomics approach has identified novel contributors to gain or loss of ciprofloxacin susceptibility in S. Typhi, expanding our understanding of the impact of fluoroquinolones on bacteria and of mechanisms that may contribute to resistance. The data also demonstrate the power of the TraDIS technology for antibacterial research.

AbstractNeutrophils release their intracellular content, DNA included, into the bloodstream to form neutrophil extracellular traps (NETs) that confine and kill circulating pathogens. The mechanosensitive adhesive blood protein, von Willebrand Factor (vWF), interacts with the extracellular DNA of NETs to potentially immobilize them during inflammatory and coagulatory conditions. Here, we elucidate the previously unknown molecular mechanism governing the DNA–vWF interaction by integrating atomistic, coarse-grained, and Brownian dynamics simulations, with thermophoresis, gel electrophoresis, fluorescence correlation spectroscopy (FCS), and microfluidic experiments. We demonstrate that, independently of its nucleotide sequence, double-stranded DNA binds to a specific helix of the vWF A1 domain, via three arginines. This interaction is attenuated by increasing the ionic strength. Our FCS and microfluidic measurements also highlight the key role shear-stress has in enabling this interaction. Our simulations attribute the previously-observed platelet-recruitment reduction and heparin-size modulation, upon establishment of DNA–vWF interactions, to indirect steric hindrance and partial overlap of the binding sites, respectively. Overall, we suggest electrostatics—guiding DNA to a specific protein binding site—as the main driving force defining DNA–vWF recognition. The molecular picture of a key shear-mediated DNA–protein interaction is provided here and it constitutes the basis for understanding NETs-mediated immune and hemostatic responses.
