Abstract
Introduction Therapeutic dry needling (DN) is effective in reducing the discomfort of chronic somatosensory tinnitus in patients with myofascial trigger points (MTP)s.
Objective To evaluate the efficacy of DN in chronic somatosensory tinnitus discomfort in patients with MTP.
Methods Placebo-controlled paired trial that included 16 patients with a diagnosis of somatosensory chronic tinnitus and with the presence of at least one active or latent MTP. Treatment was performed in two phases: (1) four sessions (one session per week for four consecutive weeks) of placebo DN and (2) four sessions of therapeutic DN with a gap (washout) of 15 days between these phases.
Results The Tinnitus Handicap Inventory (THI) variable and its emotional domain had a statistically significant reduction in therapeutic DN when compared with placebo DN (p = 0.024 and p = 0.011, respectively).The tinnitus visual analogic scale (VAS) signaled a reduction in tinnitus discomfort when compared with moments before and after therapeutic DN (p < 0.05).
Conclusion The therapeutic DN technique for MTP in patients with chronic tinnitus of somatosensory origin proved effective in reducing symptom discomfort, as measured by the THI (total score) and its emotional domain when compared with placebo DN.

Abstract
Objective Early marriage has many deleterious effects on the health of girls, such as sexual dissatisfaction, an inevitable result of the lack of sufficient knowledge about sexual issues at the time of the marriage. The goal of the present study was to determine the effectiveness of counseling based on functional analytic psychotherapy with enhanced cognitive therapy (FECT) on the sexual quality of life of married adolescent women.
Methods This clinical trial was conducted between July and October 2019 on 150 married adolescent women who met the inclusion criteria. In the intervention group, FECT was conducted in sixteen 90-minute sessions twice a week. The Sexual Quality of Life-Female (SQOL-F) questionnaire was used. When the study ended, the control group was given the choice of receiving the same intervention as the intervention group.
Results The paired t-test showed a significant difference between the mean score of sexual quality of life before (52.33 ± 23.09) and after (88.08 ± 10.51) counseling in the intervention group (p < 0.0001). According to the analysis of covariance, there was a significant difference between the score on sexual quality after counseling between the intervention (88.08 ± 10.51) and control (60.32 ± 23.73) groups (p < 0.0001). There was also a significant difference between the mean score on the four dimensions of sexual quality of life in the intervention group (p < 0.0001).
Conclusion The results showed that counseling based on FECT improved the sexual quality of life in all dimensions in married adolescent women.

Abstract
Objective To evaluate the factors associated with abortion complications following the implementation of the good-practice surveillance network Mujeres en Situación de Aborto (Women Undergoing Abortion, MUSA, in Spanish).
Methods A cross-sectional study with women who underwent abortion due to any cause and in any age group at UNICAMP Women's Hospital (part of MUSA network), Campinas, Brazil, between July 2017 and Agust 2019. The dependent variable was the presence of any abortion-related complications during hospitalization. The independent variables were clinical and sociodemographic data. The Chi-square test, the Mann–Whitney test, and multiple logistic regression were used for the statistical analysis.
Results Overall, 305 women were enrolled (mean ± standard deviation [SD] for age: 29.79 ± 7.54 years). The mean gestational age was 11.17 (±3.63) weeks. Accidental pregnancy occurred in 196 (64.5%) cases, 91 (29.8%) due to contraception failure. At least 1 complication was observed in 23 (7.54%) women, and 8 (34.8%) of them had more than 1. The most frequent complications were excessive bleeding and infection. The factors independently associated with a higher prevalence of complications were higher gestational ages (odds ratio [OR]: 1.22; 95% confidence interval [95%CI]: 1.09 to 1.37) and contraceptive failure (OR: 3.4; 95%CI: 1.32 to 8.71).
Conclusion Higher gestational age and contraceptive failure were associated with a higher prevalence of complications. This information obtained through the surveillance network can be used to improve care, particularly in women more susceptible to unfavorable outcomes.
An Analysis on the Implementation of the Evidence-based PCOS Lifestyle Guideline: Recommendations from Women with PCOS

Published: August 2021

AbstractPolycystic ovary syndrome (PCOS) is the most common endocrinological disorder affecting women of reproductive age, affecting 8–13% in this group. Women with PCOS are more likely to have excess BMI, which in turn exacerbates the symptoms of PCOS in these women. The latest evidence-based guideline recommends lifestyle management as the first-line treatment for PCOS. However, the implementation of this recommendation through health services faces a significant challenge. As part of the mapping of the implementation plan for lifestyle management in PCOS, citizen panels and semi-structured interviews were conducted to capture the voices of consumers. Women with PCOS expressed the need for multidisciplinary, integrated care as a recurrent theme. Other important considerations included health professionals who listen and are open to learning about PCOS, the empowerment of women to self-manage PCOS and the provision of peer support. Women with PCOS also expressed the key recommendation of focusing on practical skills when providing lifestyle advice. Within that, both individual and group lifestyle sessions were valued for privacy and peer support respectively and delivery by a dietitian is preferred. These recommendations by women with PCOS should be considered when developing the implementation plan for the PCOS lifestyle guideline.
A compact 1200 V, 700 A, IGBT-based pulse generator for repetitive transcranial magnetic stimulation in vivo laboratory experiments on small animals

Published: August 2021

An insulated-gate bipolar transistor (IGBT) pulse generator for repetitive transcranial magnetic stimulation used for in vivo laboratory experiments on small animals, such as mice, is reported. The pulse generator is based upon an IGBT that can switch 700 A of current for 1 ms and that has a DC breakdown voltage of 1200 V. The duration of the design’s output pulse is controlled by, and follows, an input trigger pulse. The voltage amplitude of the output pulses is determined by an external high-voltage power supply and the energy stored in a 330 µF capacitor bank. The approach enables the amplitude of the voltage applied across the coil, the length of time the voltage is applied, and the number of times the voltage pulses are applied all to be controlled and adjusted to facilitate a wide range of experimental options. This paper provides a detailed schematic of the design, design discussions, and some representative experimental results. Additionally, the reported design can be scaled to higher currents by using an IGBT with a higher current rating.
Toward a complete and comprehensive cross section database for electron scattering from NO using machine learning
Authors: Stokes P. W. , White R. D. , Campbell L. , Brunger M. J. 
Published: August 2021

We review experimental and theoretical cross sections for electron scattering in nitric oxide (NO) and form a comprehensive set of plausible cross sections. To assess the accuracy and self-consistency of our set, we also review electron swarm transport coefficients in pure NO and admixtures of NO in Ar, for which we perform a multi-term Boltzmann equation analysis. We address observed discrepancies with these experimental measurements by training an artificial neural network to solve the inverse problem of unfolding the underlying electron-NO cross sections while using our initial cross section set as a base for this refinement. In this way, we refine a suitable quasielastic momentum transfer cross section, a dissociative electron attachment cross section, and a neutral dissociation cross section. We confirm that the resulting refined cross section set has an improved agreement with the experimental swarm data over that achieved with our initial set. We also use our refined database to calculate electron transport coefficients in NO, across a large range of density-reduced electric fields from 0.003 to 10 000 Td.

Published: August 2021

Abstract
Materials used in the oil and gas industry are required to possess resilient properties to sustain operational challenges. These include high pressures and temperatures of the working fluids created by both reservoir depths and compressors combined with the inherent aggressive and corrosive components. Multiple solutions have been introduced to the industry to minimize corrosion probability in recent years. Utilizing external and internal tubular non-metallic coating as well as switching to the products entirely made of the non-metallic composites are the most commonly used and best performing solutions. This paper presents a comprehensive overview of the advances of the most promising research and development activities in the area of protective coatings as well as non-metallic composite material products with real case studies in downhole applications. Special emphases are put on the most promising technological breakthroughs such as 3D printing with non-metallic composites containing nano-sized short fibers and continuous nanofibers, which could be potentially used in the fabrication of future downhole composite products. The breakthrough solutions in composite technologies such as self-healing systems, including capsule-based, fiber-based and vascular healing network, which are perfectly aligned with the 4th Industrial Revolution are also described.

Authors: Ishmametov D A , Pomelnikova A S , Krasulya A A 
Published: August 2021

Abstracts
In this work, were studied the structure and properties of the surface composite layer on heat-resistant steel VKS-5, obtained by combined chemical and thermal treatment, combining liquid electrolysis-free boriding with gas and ion-plasma nitriding. The properties of the surface composite layer are analyzed depending on various parameters of chemical and thermal treatment to determine the optimal mode. The study of the microstructure and properties of borated layers has shown that the most optimal properties can be obtained in the boron mode at a temperature of 1010 °C with an exposure time of 8 hours. The study of the microstructure of composite layers has shown that gas nitriding produces a layer of 80 microns in size, which penetrates deep into the borated layer, and in ion-plasma nitriding, the layer size is so small that it is not possible to determine it using optical microscopy. A study of the properties of composite layers obtained by combined chemical-thermal treatment has shown that combined chemical-thermal treatment, combining boriding and ion-plasma nitriding, allows you to get the best combination of high hardness and reduced microfragility.

Published: August 2021

Abstracts
This paper presents the results of a study of aluminophosphate compositions with different contents of PMS-N copper powder and SHS-carbon obtained from lignin for the formation of current-conducting contacts on the surface of low-emission glass with electric heating. The specific volumetric resistance of coatings made of aluminophosphate composition before and after their curing was determined. It is shown that the holding temperature of 100 °C and the holding time of 5 hours can be considered the optimal mode of curing aluminophosphate compositions on low-emission glass. It is shown that the wear resistance of aluminophosphate compositions containing PMS-N copper and SHS-carbon is primarily affected by the thickness of the formed layer. The pull-off strength was determined for the resulting coating of the aluminophosphate composition containing PMS-N copper and SHS-carbon, the value of which was 8.2 MPa.

Published: August 2021

Annotation
This article examines the study of strength properties of polymer composite material, based on 3D-printed frame produced by FDM technology. The printing material is ABS plastic (acrylonitrile butadiene styrene). After the printing samples frames were soaked in pure epoxy resin with various hardeners. Subsequent curing went in two modes. After that, tensile tests were performed. The strength of impregnated, non-impregnated (clean frame) samples and samples made of pure resin was compared. Tests have shown that the strength of impregnated samples exceeds the strength of non-impregnated ones, but obtained strength value of impregnated samples were far from the expected theoretical values. It was found that low strength is associated with poor quality of the impregnation.

Published: August 2021

Abstract
This paper proposes a method for preliminary analysis of layer daynamics, it composition and assessment of deep-seated rock. Since physical knowledge is insufficient or the cannot be experimentally obtained, the phase of development and industrial launch of wells, mines, and open pits is nesessary. The method based on modeling the stress-strain state of rocks includes block-curvilinear anisotropy and creep. We develop methods that qualitatively describe the non-standard geometric shapes of deep rock layers. A block-curvilinear description of the rock model is given. We also offer the method for the effective numerical solution to the stress-strain state considering block-curvilinear anisotropy and creep. The software application is designed in the Scientific and Educational Center Supercomputer Engineering Modeling and Development of Software Systems at Bauman Moscow State Technical University (BMSTU). This software application helps to create, describe, solve and analyze both rocks and other mathematical models, as well as creep equation.
On the Asymptotics of Solutions of the Klein - Gordon - Fock Equation with Meromorphic Coefficients in the Neighborhood of Infinity
Authors: Korovina M V , Matevossian H A , Smirnov I N , Yu Smirnov V 
Published: August 2021

Abstract
In this paper we investigate the construction of uniform asymptotics of solutions for the Klein-Gordon-Fock boundary value problem with meromorphic coefficients as t → ∞. The difficulty in solving these problems is due to the fact that infinity, as known, is an irregular singular point of such equations. In the case of holomorphic coefficients, the order of degeneracy will be at most two, and in the case of meromorphic coefficients it can be arbitrary, and it will depend on the order of the poles of the meromorphic coefficients. The main method for constructing asymptotics in the neighbourhood of an irregular singular point is the method of resurgent analysis, which is based on the Laplace-Borel integral transform. Using this method, in this paper, a uniform asymptotics of the problem under consideration is constructed in a neighborhood of infinity for arbitrary meromorphic (or holomorphic) coefficients.

Abstract
In this work we investigate influence of the organic solvent addition on the deposition of graphene oxide solution by spin-coating. In order to overcome the poor wettability of polyethylene terephthalate substrate by water graphene oxide suspension we made series of multicomponent solution with different n-methylpyrrolidone to water ratio. We successfully showed possibility and good uniformity of graphene oxide films deposited from the multicomponent solution. According to AFM and Raman spectroscopy we achieved good local uniformity in all cases. The most uniform films were made with 2,35 mg/ml GO concentration. We also found that in case of 0,47 and 1,175 mg/ml concentrations we achieved few-layered graphene oxide with film thickness about 3 nm and less.

Published: August 2021

Abstract
A review of the works devoted to the synthesis and investigation of the properties of block copolymers containing fragments of polytetrahydrofuran obtained from renewable natural raw materials is presented. It is shown that the presence of chemically bonded blocks of elastic polytetrahydrofuran in rigid-chain polymer matrices increases their impact resistance and elongation at break, reduces the viscosity of the melt, and improves miscibility with other polymers. It is expected that a similar positive effect of polytetrahydrofuran elastic blocks will be observed in polymer composites filled with dispersed and continuous fibers.

Published: August 2021

Abstracts
In this work laminar steel materials of W1-7 + AISI 304, W1-7 + AISI 430, 1008 + AISI 304 and 1008 + AISI 430 model compositions were studied. The γ→α transformation temperature range bias and influence of such bias dynamics on the laminar structure stability was studied by the differential scanning calorimetry method. The study results have shown that only in the laminar steel material of W1-7 + AISI 304 model composition the γ→α transformation temperature range bias to the low temperature region and the expansion of austenite field occurred, thus ensuring retention of the laminar structure in the process of material synthesis. Also, the nature of γ→α transformation was analyzed for all four compositions which showed that the observed γ→α transformation for each model composition of laminar steel materials was direct.
