Authors: Vasudeva Shalini , Baxi Dhaval A. , Mishra Ambarish
Published: August 2022

Background: Postmenopausal bleeding (PMB) is considered a red flag symptom and warrants further examination and evaluation. Trans-vaginalsonography (TVS) can be used reliably to diagnose fibroids, polyps and thickened endometrium. Hysteroscopy is considered “gold standard” for evaluating endometrial cavity. It provides direct visualization of endometrial cavity. It can have both diagnostic as well as operative purpose however, it is not cost effective, an invasive procedure and requires anesthesia and expertise. Present study was designed and carried out to study aetiology and prevalence of PMB in Central India as well as to evaluate the efficacy of TVS and hysteroscopy in diagnosis of different endometrial pathologies in patients with PMB.Methods: This prospective study included 82 post-menopausal women with PMB who attended the gynaecological clinic from December, 2019 to December, 2020 at Motherhood hospital, Indore, India after ethical clearance. A detailed history, examination followed by transvaginal sonography was made. Hysteroscopy was then performed, and biopsy was obtained in all patients. Hysteroscopic and sonographic images were then analyzed and conformed with the histopathologic diagnosis.Results: Most common endometrial pathology was atrophic endometrium followed by endometrial polyp and hyperplasia. Endometrial carcinoma was observed in (3.66%) females. Other findings in cases of secretory, proliferative endometrium and endometritis accounted for 6.09%. The diagnostic accuracy of ET by TVS at a cut-off point of 5 mm was 94% with sensitivity 89.3%, specificity 100%, PPV 100% and NPV 88%. The diagnostic accuracy of hysteroscopy was 98% with sensitivity 96.4%, specificity 100%, PPV 100% and NPV 95.7%.Conclusions: TVS with ET measurement should first line investigation in the evaluation of women with PMB with suspected endometrial pathology because of cost effectiveness, easy accessibility and non-invasive method of diagnosis. Although hysteroscopy is more specific and sensitive, in poor resource settings it should be limited to cases with illdefined endometrial lining, recurrent/ persistent bleeding and cases with endometrial thickness greater than 5 mm irrespective of endometrial echotexture.

Published: August 2022

Background: Fibroblasts from different parts of the human body have been used in cell biology, drug discovery and cell therapy studies. One of the most available sources of human fibroblasts is neonatal foreskin. Not only do these cells have woundhealing applications, but they are also the most popular source for pluripotent stem cell biotechnology. Moreover, several studies have indicated that different sources of fibroblasts display similar features to mesenchymal stem cells.
Objective: Generation and establishment of new human foreskin fibroblast cell lines called Yazd human foreskin fibroblasts (YhFFs).
Materials and Methods: In this lab resources study, the production of 3 YhFF cell lines (YhFF#8, YhFF#17, and YhFF#18) is reported. Their biological features were characterized using immunofluorescence, polymerase chain reaction, and flowcytometry for mesenchymal markers such as fibronectin, vimentin, CD44, CD73, CD90, CD105, and hematopoietic markers CD34 and CD45.
Results: The YhFF cell lines were passaged more than 40 times and their normal karyotype was checked using G-binding. Similarly to previous reports, the flow cytometry analysis revealed that the YhFF cell lines displayed mesenchymal stromal cell characteristics.
Conclusion: This study will contribute to the development of clinical-grade cell-based products such as micro-vesicles and exosomes for future therapeutic applications in regenerative medicine.

Background: Herbal medicine could be effective at treating various illnesses. Hysteroscopy can be an effective method for assessing the uterus in terms of anatomical, physiological and pathological anomalies.
Objective: This study aims to evaluate the effect of evening primrose oil (EPO) on cervical preparation in women candidates for hysteroscopy.
Materials and Methods: This study was a double-blind, randomized controlled clinical trial including 160 women candidates for diagnostic hysteroscopy who were referred to Alzahra hospital from August 2019-March 2020. They were divided into 2 groups. Group A received 100 mg EPO as a soft gel capsule 6 hr before the hysterectomy in the posterior vaginal fornix. Group B received a placebo. After receiving the treatment, primary and secondary outcomes were evaluated in the groups.
Results: The average Hegar size in the EPO group was larger than in the control group (p < 0.001 for both). Also, the need for mechanical dilation, the time taken until the first resistance and the time of dilatation completion in the EPO group were significantly less than in the placebo group (p < 0.008 for all). There was also greater ease of dilatation in the EPO group. Side effects such as uterine rupture, false passage, cervical rupture, allergic reaction, abdominal pain, nausea, diarrhea, headache and increase of bowel movements were not reported in any cases.
Conclusion: Based on the findings of the present study, EPO is effective for cervical preparation in women undergoing hysteroscopy.

Authors: Silva Francisca , Fiadeiro Paulo , Fonseca Elsa
Published: August 2022

Studying the three-dimensional structure of paper fibrous networks is an important step towards understanding the relationship between manufacturing conditions and the resulting microstructural and mechanical properties. Digital holography is a promising three-dimensional imaging technique enabling quantitative phase evaluation of micro and nano-fibres. One of the advantages of this high-resolution method is the ability to perform numerical refocusing at several depths from a single shot acquisition. In this work, the suitability of 22 focusing functions to accurately identify the positions of cellulose microfibers, using digital holography, was inspected. The best performing metrics were identified and the trade-off between metric accuracy and robustness to variable conditions and their computational complexity were discussed.

Published: August 2022

Hardwood species have a complex cellular structure consisting of fibres, vessel elements and parenchyma cells with different chemical compositions. However, the presence of vessels with significant dimensions in their structure is a recurrent problem in the operation of industrial UWF paper printing. Since the 1980s, vessel picking and ink refusal are problems that paper professionals have tried to solve, but solutions for these have not yet been fully found. If vessels are concentrated in a stream, they can be pre-treated (e.g., by mechanical refining) and reincorporated into the pulp. Other strategies aim at vessel enzymatic and/or chemical passivation and sheet surface chemical treatment, altering the vessel adhesion to the fibre network. This requires vessel concentration at laboratorial level for proper chemical studies, such as FE-SEM, μ-XPS, TOF-SIMS and μFTIR. The main objective of our experimental study was to examine bleached kraft pulp E. globulus vessel and fibre composition. For this we performed EDX and μ-FTIR analysis on both fibre and vessel elements, and obtained the carbohydrate composition, the total acids content, the hexenuronic acids content and the zeta potential.
Keywords: E. globulus, vessel, EDX, μ-FTIR, sugar content, zeta potential

Published: August 2022

This study focused on five different subspecies of Portuguese Daucus carota L., to identify the main compounds in the essential oils of umbels from each subspecies. The isolation of the essential oils was performed by hydrodistillation methods followed by further composition analysis by gas chromatography-mass spectrometry, ultimately demonstrating that each subspecies had different major compounds. This study concluded that the main compounds found in Daucus carota subsp. maritimus were geranyl acetate, followed by trans-methyl-isoeugenol, α-pinene, cis-asarone and elemicin. Daucus carota subsp. hispidus presented with the major compounds as geranyl acetate, caryophyllene oxide, trans-methyl-isoeugenol and sabinene. For Daucus carota subsp. maximus, the major compounds were cis-asarone, geranyl acetate and elemicin, which was similar to Daucus carota subsp. carota which presented with the major compounds as geranyl acetate, cis-asarone, trans-methylisoeugenol and α-pinene. Finally, the major components of Daucus carota subsp. sativus were carotol and daucol.

Authors: Borges Boaventura , Baía Ana , Lopes Ana , Pacheco Maria José , Ciríaco Lurdes , Fernandes Annabel
Published: August 2022

Electro-Fenton process was applied in the degradation of the textile dye C. I. Direct Red 80 (DR80), using a boron-doped diamond anode and a carbon-felt cathode. The influence of the applied current density and of the type of iron source was evaluated. The iron sources studied were iron sulfate, ferric chloride, iron oxide and chalcopyrite, a natural iron-containing mineral. The obtained results showed that the electro-Fenton process is effective in the DR80 degradation and in the pollutant load elimination. Higher treatment efficiencies were attained when using iron sulfate as iron source. Still, the results obtained with the natural mineral chalcopyrite were quite promising. Although DR80 removal was more efficient at lower applied current densities, the same was not observed for the chemical oxygen demand removal, indicating that, at lower applied current densities, the dye is not completely mineralized, but rather transformed into other by-products.

Authors: Correia José , Almeida Adelaide , Durão Anabela , Pardal Ana , Borralho Teresa
Published: August 2022

Due to the negative effects of its main inflows, the water quality of Roxo stream, located in southern Portugal, an area characterized by Mediterranean climate, is degraded, causing consequences in irrigated agricultural activity. The eco technology of floating beds was used to improve the quality of this water. Three Vetiver zizinioides floating beds (3.3 m2/unit; density 40.5 plants/m2) were placed on the Roxo stream in May 2020 and the water quality was monitored until December 2020 in two places: at the floating beds location and 100 m higher up in the stream. The load mass was calculated for both sampling points and the removal rate for each parameter was monitored. The average removal rates obtained were: (i) TN = 33%; (ii) TP = 43%; (iii) COD = 44%; and (iv) Cl- = 15%. The DO level increased slightly, and the pH remained neutral. Although the water quality improved, the quality was still not high enough to be able to use the water for irrigation and to achieve good ecological status.

Treatment of Industrial Effluents by the Microalgae Selenastrum Sp.
Authors: Escobar Bruno , Cunha André , Simões Rogério
Published: August 2022

High consumption of clean water results in the generation of effluents that need to be treated and then safely discarded. Conventional methods for such treatment often do not offer an economical and sustainable result; therefore, new methods are needed, such as microalgae usage. Microalgae are unicellular beings capable of rapid adaptation, growth, and production of compounds of interest (pharmaceuticals, biofuels and others). This work aimed to study the effectiveness of the microalgae Selenastrum sp. in the treatment of effluents from the textile and pulp & paper industries, as well as the respective effects on its biomass development and accumulation of compounds. Four types of culture were carried out (for each type of effluent, a control, and a control with addition of glucose) lasting eight days, in duplicate, all with the addition of a standard culture medium and controlled abiotic factors. Analyses for compound removal (chemical oxygen demand and colour readings on the 200–800nm range) and biomass development (cell number, its dimensions, and weight) were performed four times during the process. At the end of the experiments, the average removal in effluents for COD and colour were 56.6% and 32.7% respectively, in addition to a biomass accumulation of 0.45 g/L. These results were comparable to those obtained for the control cultivation using glucose as a carbon source (70.0% COD removal and 0.51 g/L biomass accumulation). These results demonstrate the effectiveness of Selenastrum sp. in the treatment of industrial effluents, its resilience in stressful environments and the potential use of its accumulated compounds for biotechnological purposes.

Water Reuse: A Risk Assessment Model for Water Resources
Authors: Rebelo Anabela , Bento Amaro Albertina , Quadrado Felisbina
Published: August 2022

The increasing demands for water for multiple purposes combined with climate change challenges are leading to water scarcity and quality deterioration. Portugal is vulnerable to the impacts of climate change and therefore, the use of reclaimed waters has been identified as a suitable alternative water source for non-potable uses, such as irrigation, to overcome water shortages. In the last two years, new policies for water reuse have been approved at the Portuguese and European levels. The legal frameworks are supported in the international guidelines developed by the International Organization for Standardization, namely for irrigation, urban uses and health risk assessment. In this way, all reuse projects must follow a fit-for-purpose approach, i.e., the water quality needs to meet the requirements of its specific end-uses without compromising public health or the surrounding environment, and all reuse projects must conduct a risk assessment for health and the environment. Quantitative, qualitative or semiquantitative models can be used. Although a quantitative assessment may be desirable, these models tend to be complex and present high uncertainty. Furthermore, these usually require extensive data which are often not available. Accordingly, this study intended to develop a conceptual model to deal with the risk assessment for water resources, namely surface and ground waters. A semi-quantitative approach was employed for the risk characterization, using empirical qualitative judgment to assess the relative importance of hazards, exposure routes, scenarios and barriers in place. The use of a strategic assessment allows the quality standards that meet the needs of each project to be validated. The developed model was applied to a case study to illustrate its applicability.

Chemical and Mineralogical Characterization of Biomass Ashes for Soil Reinforcement and Liner Material
Authors: Studart André , Marchiori Leonardo , Vitoria Morais Maria , Albuquerque António , Gabriel Almeida Pedro , Cavaleiro Victor
Published: August 2022

Mineralogical and chemical evaluations are necessary to investigate the background and origins of materials. In terms of residues commonly produced around the world, ashes biomass stands out for its high calorific capacity and use for energy production at thermoelectrical facilities. Given current sustainability issues and new demands from society, ashes and soil from pine biomass in the Castelo Branco region were investigated to research possible anthropogenic contaminations, heavy metals among their composition, and their physic-chemical characteristics. These properties can be used to define possible valorisation methods through residue introduction into the soil for its reinforcement and liner application. The results indicated that ashes biomass could help achieve these objectives and could be introduced into the soil, due to its enrichment with pozzolanic minerals and fine granulometry, while having a low-density, which could reduce final weight; however it was considerably different from the original biomass, and contained anthropogenic contaminations and high concentrations of heavy metals.

Published: August 2022

Biomass ashes (BA) have been intensively studied as amendments for soil in earthworks. This paper aimed to geotechnically characterize BA from pines and olive trees compared to the soil from Castelo Branco, Portugal. Namely, granulometry, specific gravity, Atterberg limits and optimal compaction values were obtained and analyzed in order to valorize the residue incorporated into soils. This work is part of broader efforts to develop an alternative material that can be used in hydraulic barriers as liners and for soil reinforcement. Thus, BA can contribute to reductions in weight and plasticity, and filling properties. Further studies are needed, particularly mechanical and hydraulic performance tests.

Published: August 2022

Background & Aim: Despite the well-known benefits of practicing self-reflection in educational settings, little is known regarding the effects of applying it in clinical settings. The objective of the current study was to investigate the effects of self-reflective practice on cognitive emotion regulation and resilience of mothers of preterm infants in the NICU.
Methods & Materials: A total of 90 mothers whose preterm infants were admitted to NICU enrolled in the current non-randomized clinical trial study by convenience sampling (n=45 in each group). The data of the control group were gathered prior to the intervention group. Pre- and post-test data were gathered using the demographic questionnaire, the Cognitive Emotion Regulation Questionnaire, and the Conner and Davidson Resilience Scale. Self–reflection practice was designed and conducted based on Gibbs' reflective cycle for the intervention group, which applied a blended model (face-to-face and virtual). Statistical analysis was conducted by SPSS-25 and using the repeated measure ANOVA.
Results: Using ANCOVA, the results indicated that the self-reflection practice was effective in improving cognitive emotion regulation (F=66.01, P≤0.001, Eta=0.60) and resilience (F=89.43, P≤0.001, Eta= 0.67) among mothers in the intervention group. 
Conclusion: Self-reflection practice was an effective intervention for improving mothers’ skills, helping them be more resilient, and assisting them in regulating their emotions. Further studies should support the current study findings in different clinical settings.

Published: August 2022

Bu yazıda Gürsel Korat’ın Unutkan Ayna romanında travmatik tanıklığın mekân ve bellekle kurduğu ilişki üzerinde durulacaktır. Romandaki bellek ve travmatik tanıklığın temellendirilmesinde Maurice Halbwachs’ın ortaya koyduğu kolektif bellek formülasyonu ile Paul Ricoeur ve Giorgio Agamben’in tanıklık nosyonuna dair tespitleri kaynak alınacaktır. Kolektif bellek, toplulukların ortak deneyimlerine vurgu yapan bir kavramdır. Aynı deneyimde buluşan insanların bir topluluk olarak deneyimlerine atfettikleri anlamı kuran bir çerçevedir. Mekânın değişimi, kolektif belleğin şekillenmesinin dinamik bir olgu olduğunu gösterir. Romanda travmatik tanıklığı belirleyen mekân, bellek gibi farklı tahayyüllerle genişleyen ve farklılaşan bir toplumsal çerçeve kurmak amacıyla kullanılmaktadır. Tanıklıklar, bellek mekânını oluşturan ritüeller gibi topluluğun deneyimine ilişkin izleri bir araya getirir ve böylece geçmişin travmalarının yönetilmesini sağlar. Travma, söze dökülemeyen, bilişsel dizgede kronolojik olarak dizilemeyen ve zihnin kabul etmediği bir deneyim olduğu için tarihte yaşanan travmatik kayıplar kamusal suskunluklardan sıyrılıp edebiyata dönüşemeyebilir. Korat, ikili karşıtlıklarla kurulan tarihsel çerçeveyi ve kamusal suskunluğu aşındırırken tarihin kayıtlarının karşısına hikâye anlatıcılığını koymuş ve bunu hümanist bir tarih yazımının ilk basamağı olarak işaretlemiştir.

Currently, the treatment of patients with inflammatory diseases of the larynx in most cases is multi-stage, long-term, and requires numerous techniques using specialized equipment. In the daily work of an otorhinolaryngologist with inflammatory diseases of the larynx, drugs are most often used in the form of injections or oral use. Aerosol therapy enables fast and effective therapeutic action with the use of a relatively small dose of the drug and a significant reduction in the negative systemic effect. An effective means of treating diseases of the upper respiratory tract is irrigation and inhalation therapy using sea water, which moisturizes dry mucous membranes, promotes rapid softening and removal of crusts. To establish the therapeutic efficacy of the use of Aqua Maris Strong for Throat in the complex treatment of inflammatory diseases of the larynx, 76 patients suffering from inflammatory diseases of the larynx were selected, who were divided into the main and control groups of the study. Patients of the main group as part of complex therapy for inflammatory diseases of the larynx received inhalation administration of the drug "Aqua Maris Strong for Throat ". The inhalation procedure consisted of 2 inhalations lasting 10 minutes, 2 times a day. The control group of patients – 37 patients received traditional etiotropic treatment of inflammatory diseases of the larynx. As the study showed, in patients who received inhalation administration of the Aqua Maris Strong for Throat preparation as part of the complex therapy of inflammatory diseases of the larynx, positive dynamics of complaints, normalization of the laryngostroboscopic picture were noted faster than in patients of the control group. The advantage of therapy using Aqua Maris Strong for Throat was also confirmed by the restoration of cytopathological changes in local cellular protection, in the form of a decrease in signs of deepithelialization, mucociliary insufficiency, phagocytosis of cellular elements, a decrease in the concentration of pathological flora on the laryngeal mucosa in a shorter period of time than in patients in the control group.

The article presents the examination and treatment of 58 patients with precancerous and malignant lesions of the larynx. To determine the size and prevalence of the tumor process, to conduct postoperative monitoring, it is most appropriate – in addition to endoscopic methods—to use magnetic resonance imaging (MRI) with intravenous introduction of a contrast agent. Accurate diagnosis allows you to choose the optimal access, radically remove the tumor, and maximize the preservation of the operated organ. Methods of using a CO2 laser for endolaryngeal tumor removal are proposed.

Parietal edema/edematous syndrome, appearing in isolation in the paranasal sinuses, is the most common radiographic finding. However, the transformation of the syndrome into polypous tissue, the relationship with the formation of clinical forms of rhinosinusitis are poorly understood. Objective. To reveal the relationship of edematous syndrome of the mucous membrane of the paranasal sinuses with meteorological elements (humidity, temperature, precipitation, wind speed). Describe the mechanism of the pathogenetic relationship between increased water vapor pressure and edematous syndrome of paranasal sinuses. Materials and methods. The study included 504 people who performed computed tomography in the units of Saint Petersburg City Hospital No. 40 in 2019, of which 243 were men, 261 were women. Age from 33 to 56 years old, mean age 46.45 ± 1.87. On each of the three selected days of the month, 14 patients were determined (methods of random sampling) who underwent CT of paranasal sinuses. Results. The processes of condensation in the sinuses were evaluated using a computer thermotechnical calculation. A connection was found between the edematous syndrome of the mucous membrane of the paranasal sinuses and meteorological elements (moderate correlation between relative humidity and the presence of edema, a strong correlation between the average wind speed and edema of paranasal sinuses). The mechanism of pathogenetic connection of increased water vapor pressure with edematous syndrome of paranasal sinuses is described. The main types of pathological processes were identified: film condensation with a dew point on the mucosal surface, interstitial condensation with a dew point in the thickness of tissues, and various combinations thereof.

The development and implementation of endoscopic techniques and instruments into rhinosurgery have brought this branch of medicine to a qualitatively new level. The access to the frontal sinus is currently considered the pinnacle of skill. This is due to the pronounced anatomical variability of the anterior ethmoid labyrinth and close location of anatomically significant structures; intraoperative damage of these structures can result in severe consequences for the patient. Attempts to regulate frontoethmoidal anatomy are still in progress currently; however, there is no yet single classification that satisfies most specialists and meets the requirements of practice. In spite of urgency of the issue, it has received undeservedly little attention in the Russian scientific literature. The aim of this paper is to review in detail options to systematize structures of the ethmoidal labyrinth involved in the formation of the boundaries of the frontal recess and the drainage pathway of the frontal sinus. Special attention is paid, in particular, to the aspects of systematization of the anatomical elements of the anterior ethmoid labyrinth and the frontal recess. The authors conclude that the only way out for a practical doctor is a constant continuous expansion of the theoretical and practical base and careful preoperative preparation in each case, using the most convenient classification system for the rhinosurgeon.

Si bien la regulación de las acciones sin derecho a voto en la Ley General de Sociedades es en términos generales adecuada, hay algunos aspectos referidos a los derechos conferidos a sus titulares que han generado discusión en los últimos años. Nos referimos al contenido del dividendo preferencial que les corresponde a las acciones sin voto, así como al derecho de voto residual en juntas especiales y al alcance del derecho de suscripción preferente que les corresponde. En el presente artículo se opina sobre el tratamiento que debieran tener estos derechos, de tal manera que se pueda contribuir a un mayor uso de la figura de las acciones sin derecho a voto como mecanismo de capitalización y financiamiento en las sociedades anónimas.

Los últimos acontecimientos mundiales como la pandemia de la COVID-19 y los distintos escenarios políticos trajeron consigo una gran incertidumbre económica que todavía permanece, especialmente, en el país. En efecto, el sector de fusiones y adquisiciones de empresas (M&A) en el Perú no ha sido ajeno a ésta. Sin embargo, es tarea de los agentes del mercado crear estrategias para mitigar la incertidumbre y generar incentivos para reactivar las inversiones tanto de capital extranjero como peruano.En esa línea, en el presente artículo, las autoras han identificado al mecanismo de pago de precio que se emplea en un contrato de compraventa de acciones como clave en la reactivación y potenciación de las operaciones de M&A en un contexto de incertidumbre económica. Así, las autoras desarrollan los mecanismos de pago de precio que se han empleado en los contratos de compraventa de acciones a efectos de dinamizar el mercado de M&A.
La ‘huida’ a los NFT: Sobre los ‘límites prácticos’ de la protección de los Derechos de autor del ordenamiento peruano en el caso de las obras pictóricas digitales

El régimen de protección de derechos de autor peruano se adjunta a un sistema cerrado de limitaciones y excepciones. Sin embargo, la rigurosidad de este presenta “límites prácticos” en su aplicación, los cuales afectan negativamente a los creadores de obras pictóricas. En ese sentido, se reflexionará en torno a si efectivamente se permite la realización de la finalidad de la institución de los derechos de autor. Asimismo, ante la creciente popularidad de la actividad comercial de obras pictóricas digitales a través de tokens no fungibles (conocidos como NFT por sus siglas en inglés), resulta menester reflexionar sobre la razón de la ‘huida’ desde la comercialización tradicional del arte pictórico digital hacia esta nueva alternativa para hacer frente a la alta difusión y reproducción de sus obras en la red. Así, se demostrará la poca efectividad de la protección e incentivo del ordenamiento hacia la libertad creativa, intelectual y artística.
Structural and morphological properties of contacts to a (111) orientation monosilicon substrate based on aluminum with a Ti and w – 10 % Ti barrier layer
Authors: Snitovsky Yuri P.
Published: August 2022

The paper presents the results of studies on the formation of ohmic contacts to monosilicon from aluminum in the presence of a thin-film barrier layer based on titanium and tungsten.

The purpose of reseach: to study the mechanism of solid-phase interaction in Al/Ti/Si and Al/Ti/SiOx/Si systems during the formation of contacts to (111) orientation silicon based on aluminum with a Ti and W 10% Ti barrier layer, their structural and morphological properties and ways to manage this mechanism. The study revealed relationships between the structure and properties of the films, which can lead to marriage or a decrease in the service characteristics of the IC due to a violation of the structure of the film composition.

Methods and objects of research: It is shown that the difference in the behavior of thick and thin oxides is consistent with the thermodynamic data for bulk materials. In this case, the formation and final electrical properties of the silicidesilicon interface region depend on the presence of unavoidable impurities present during the deposition of the reacting metal.

As a result of electron microscopic studies of the Al/WTi/Si system, it was found that the tungsten10 % (wt.) titanium barrier layer is reliably thermally stable up to a temperature of 773 K, regardless of the layer thickness (0.050.12 m).

The development and improvement of training algorithms is of special scientific and practical interest in the field of application testing. In the context of expanding the field of application of probabilistic models of Bayesian networks for solving testing problems, there is a need for stochastic assessment of hidden parameters, as well as the formation of a complete joint distribution across all variables. The growth of the dimension of probabilistic models for solving various scientific and applied problems requires the development of optimal procedures for training parameters in accordance with existing algorithms, as well as the development of new solutions. The subject of the study is testing models used to represent probabilistic relationships between individual test modules, which allow timely configuration and use of test generation to detect certain groups of program errors. The aim of the study is to develop effective stochastic algorithms for training parameters of test models, which allow you to obtain more accurate values ​ ​ of a priori distribution of parameters. The study proposes methods and algorithms for training parameters of testing models based on a stochastic gradient in combination with the Monte Carlo method using Markov chains to form a preliminary distribution over all hidden variables in accordance with the available set of training data. The results of the study showed the viability of theoretical assumptions and made it possible to implement the optimal algorithm for solving the problem of training probabilistic models of testing web applications. The proposed methods and algorithms are constructive and make it possible to increase the accuracy of training parameters of test models in the presence of hidden variables.
