Published: August 2022

Abstract
In this article, the dynamic fracture of polymethyl methacrylate specimen with two symmetrical prefabricated notches was investigated by dynamic caustics experiment and distinct lattice spring model (DLSM). Three variables in respect of the pitch between these prefabricated notches, a = 10 mm, 15 mm, and 20 mm, were designed here. The failure form, crack propagation trajectory, crack propagation velocity, stress state at crack tip, ratio of damaged lattice, and load-displacement curve of the specimen under different working conditions were analyzed and compared. Results show that DLSM can invert the results very well. Finally, the impact factors (support constraints and heterogeneity) involved in this experiment were quantitatively analyzed by DLSM.

OBJECTIVE
Children with complex chronic conditions (CCCs) and their parents benefit from supportive serious illness care when their conditions are severe and impact their quality of life and stress. This includes not only expert medical care but also effective relationships with the clinical team. Existing data suggest that there are opportunities for improvement. This study’s aim was to explore important aspects of the relationships and resources that facilitate supportive serious illness care among children with CCCs and their parents.

METHODS
We conducted semistructured interviews with adolescents and young adults (AYAs) with CCCs (aged 13–35 years), and parents of children with CCCs across 2 academic pediatric centers in the United States from December 2018 to April 2019. Transcripts were iteratively coded and analyzed by a team that included a sociologist, pediatric intensivist, and palliative care researcher by using inductive and deductive thematic analysis.

RESULTS
Seven AYAs with CCCs and 9 parents participated (16 total; 1 AYA–parent dyad). Two key categories were identified around relationships with the clinical team: trust and fostering collaboration. Three key categories related to resources are information needs, making sense of life with illness, and supportive community. Many of the key categories and themes identified by participants had both tangible and intangible components and revealed the distinct yet interconnected nature of these aspects of care.

CONCLUSIONS
Awareness and cultivation of relationship and resource support through innovative interventions and attention to those with increased needs in these areas may improve the serious illness care provided to children with CCCs and their parents.
Boron nitride nanotubes: A review of recent progress on purification methods and techniques
Authors: Maselugbo Adesewa O. , Harrison Haley B. , Alston Jeffrey R. 
Published: August 2022

AbstractBoron nitride nanotubes (BNNTs) will be one of the most important materials of this century. Recent synthetic advances have made BNNTs viable candidates for advanced multifunctional materials. Like carbon nanotubes and graphene, BNNTs and h-BN have extraordinary physical properties. Unlike CNTs, BNNTs have a wideband gap; they are piezoelectric, have neutron radiation shielding capability, and can withstand degradation up to 1000 °C. BNNTs could be the next big leap for nanocomposite advanced applications; however, significant scientific challenges must be addressed. Predominantly, large-scale synthesis techniques are immature. Production products require careful characterization, analysis, and purification. Impurities such as boron, amorphous BN, and h-BN lead to difficulty studying chemical modification and translation of BNNT properties. This review synthesizes relevant literature and state-of-the-art techniques regarding purification methods of BNNTs, classified as physical, chemical, and multi-step techniques and their applications. The review also discusses BNNT synthesis methods and future research directions.Graphical abstract
Glucocorticoids and mineralocorticoids in blood plasma as markers of early diagnostic adrenal cortical tumors
Authors: Roienko Yurii 
Published: August 2022

Adrenocortical tumours of the adrenal glands are formed when the cells of the cortical layer grow. The morphological and histological structure of benign adrenal tumours is variable, which complicates their early diagnosis. The study of the levels of hormones in the adrenal cortex along with the analysis of the symptoms of the disease will allow not only to differentiate hormone-producing tumours, but also to predict the direction of metabolic processes, which will make it possible to choose the right treatment regimen and prevent complications from other organs.
The aim of the study is to determine the level of cortisol and aldosterone and assess the state of the pituitary-adrenal and renin-aldosterone systems in patients with various types of adrenocortical adenomas.
Materials and methods. The state of the hormonal status of the adrenal cortex was assessed by determining the level of glucocorticoids - cortisol and mineralocorticoids - aldosterone using a direct quantitative enzyme immunoassay. The level of adrenocorticotropic hormone (ACTH) and renin was determined by immunochemical methods using monoclonal antibodies specific for ACTH and renin.
Research results. An increase in the level of cortisol was detected against the background of a decrease in the level of ACTH in patients with cortisol-producing adrenocortical adenomas. It is shown that the aldosteronism we discovered in patients with aldosterone-producing adenomas develops against the background of an unchanged renin level and an increase in the aldosterone/renin ratio.
Conclusions. The development of hormone-dependent adenomas of the adrenal cortex is accompanied by an imbalance in the work of the pituitary-adrenal and renin-aldosterone systems, the direction of changes of which can serve as a criterion for early diagnosis of adrenocortical adrenal adenomas

Published: August 2022

The object of research is the process of obtaining silicon nanomaterials for lithium-ion batteries of energy storage devices, and the subject of research is the technology of gas-phase plasma-chemical synthesis for the production of Si-nanoparticles.
In the course of the study, numerical simulation methods were used, which made it possible to determine the parameters of temperature fields, velocities and concentrations. To study the processes of synthesis of nanopowders, a plasma reactor with an electric arc plasma torch of a linear scheme and using an argon-hydrogen mixture as a plasma-forming gas was developed. To analyze the influence of an external magnetic field on the control of the plasma jet parameters, a series of experiments was carried out using an electric arc plasma torch on plasma laboratory facilities with a power of 30 and 150 kW.
The influence of a magnetic field on the process of formation and evaporation of a gas-powder flow in a plasma jet was studied by determining the configuration, geometric dimensions, and structure of the initial section of the jet. In this case, the dispersed material – silicon powder was fed to the plasma torch nozzle section according to the radial scheme. Experimental confirmation of the phenomenon of elongation of the high-temperature initial section of the plasma jet in a longitudinal magnetic field has been obtained. The experimental results indicate that the creation of a peripheral gas curtain significantly changes the characteristics of heat and mass transfer in the reactor. It should be expected that for optimization it is possible to exclude the deposition of nanosilicon particles on the walls of the reactor and provide conditions for continuous operation. The effect of two-phase flow, heat transfer, and mass flow of nanoparticles, including the surface of a plasma reactor with limited jet flow, in the processes of obtaining silicon nanopowders has been studied. This made it possible to correct a number of technological characteristics of the process of constructive design of the actions of plasma synthesis of nanopowders.
The patterns obtained can be used for constructive and technological design in the creation and development of a pilot plant for high-performance production of nanosilicon powders.
Accuracy assessment of marker recognition using ultra wide angle camera

Published: August 2022

Modern devices that support augmented reality technology are widely used in various fields of human activity, including medicine. Head mounted displays may provide an attractive alternative to traditional surgery navigation systems because allow users to stand at the first point of view and interact with objects in their surroundings naturally. Thus, the object of research in this study is recognition accuracy of fiducial markers in zones where ultra-wide angle camera distort the most. This is motivated by the need to increase user workspace for interaction with markers compare to the workspace provided with such popular augmented reality device as Microsoft HoloLens 2.
In this study, the recognition accuracy is evaluated using ArUco square markers with taking into account different marker sizes and their positions in the camera view space. The marker positions include the center of the camera view space as well as such zones where lenses distort the most as top left, top right, bottom left, and bottom right corners.
Obtained results show that recognition accuracy is good enough to be applicable for surgical navigation and failures referred to the distortion occurs are available in less than 0.2 % of all cases. This gives a possibility to increase workspace for interaction with markers compare to the Microsoft HoloLens 2. At the same time, the workspace for interaction could not reach the actual view space of the camera since recognition fails in cases where marker’s body is partially visible in the captured image (i. e., marker position is at the image boundaries).
Research of consumer properties of organic oils
Authors: Tkachenko Alina 
Published: August 2022

The object of the work is organic cold-pressed oils: sea buckthorn oil, amaranth oil, sesame oil. In the work, consumer properties of vegetable oils were studied: organoleptic characteristics, peroxide value, fatty acid composition. Among the organoleptic indicators, transparency, smell, color and the presence of sediment were studied. To determine the smell, the oil was applied in a thin layer on a glass plate. In order to study the color, the oil was poured into a glass with a layer of 50 mm and examined in transmitted and reflected light on a white background. Determination of transparency was carried out in the cylinder after settling at a temperature of 20 °C for 24 hours. To detect sediment in the settled oil, the number of divisions in the lower part of the cylinder occupied by oil sediment was noted. All organoleptic characteristics correspond to the limits of the norm. All samples are transparent, do not contain sediment and foreign odors. The color is inherent in each type of oil. In all samples, the peroxide number was studied. The amount of peroxides was determined by the iodometric method. In sea buckthorn oil, the peroxide number is 4.6 ½O mmol/kg, sesame – 4.8 ½O mmol/kg, amaranth – 4.3 ½O mmol/kg. The indicated indicators correspond to the norm. The fatty acid composition of the oil was determined by gas chromatography on an HP 6890 gas chromatograph (Agilent, USA). The content of meristic, palmitic, stearic, oleic, linoleic and linolenic acids was studied in oils. Oleic acid (18:1ω–9) is found in the largest amount in sesame oil (29.29 %). The content of linolenic acid (18:2ω–6) is the highest in amaranth oil (49.29 %). The content of linoleic acid (18:3ω–3) is the highest in sea buckthorn oil (19.28 %). Further research is planned to be devoted to the effect of vegetable organic oils on the lipid fraction of flour products.

Aim. To assess the prognostic role of cardiac biomarkers (galectin-3, soluble ST2 (sST2), and N-terminal pro-brain natriuretic peptide (NT-proBNP)) in risk stratification of adverse cardiovascular events (CVEs) in patients with heart failure (HF) after implantation of an automatic implantable cardioverter-defibrillator (AICD) within 12-month follow-up period.Material and methods. The study included 57 patients (men, 41; mean age, 65 (59; 68) years) with coronary artery disease and NYHA class II-III HF with left ventricular ejection fraction of 34 [26; 40]%. All patients were implanted with AICD. Serum levels of NT-proBNP, sST2, and galectin-3 were determined by enzyme immunoassay prior to AICD implantation.Results. It has been established that in order to stratify the risk of unfavorable HF in patients after AICD implantation for 12-month follow-up, all three studied biomarkers can be considered as prognostic factors. Thus, an increase in the level of NT-proBNP ≥1046,6 pg/ml (AUC=0,68; p=0,009), sST2 ≥34,43 ng/ml (AUC=0,78; p<0,0001) and galectin-3 ≥11,6 ng/l (AUC=0,72; p=0,0014) predicts a high risk of adverse CVEs. The combination of sST2 and galectin-3 increased the predictive value of the analysis (AUC=0,84; p<0,0001), while the addition of NTproBNP did not increase the accuracy of risk stratification.Conclusion. The determination of the combination of galectin-3 and sST2 can potentially help identify a group of patients with HF after AICD implantation with a high risk of adverse CVEs for intensification and optimization of treatment.
Maximum time between cardiac cycles in atrial fibrillation for assessing the risk of arterial thromboembolism
Authors: Germanova O. A. , Germanov A. V. , Shchukin Yu. V. 
Published: August 2022

Aim. To assess the development of thromboembolic events in different types of atrial fibrillation (AF), which differ in the maximum time between cardiac cycles.Material and methods. The main group included 80 patients with permanent AF, while the control one — 88 people without AF. The following investigations were performed: echocardiography, 24-hour electrocardiographic (ECG) monitoring; ultrasound of extracranial arteries, aortic branches, lower limb arteries; sphygmography of the common carotid and posterior tibial arteries. If required, coronary angiography, cerebral angiography, brain computed tomography were performed. According to 24-hour ECG monitoring, all patients of the main group were divided into 2 subgroups (A and B) depending on the maximum time between cardiac cycles in AF: subgroup A (n=42) — patients with a maximum time between cardiac cycles <1,5 seconds, subgroup B (n=38) — ≥1,5. The followup period lasted 1 year. During the follow-up period, the development of arterial thromboembolic events was analyzed.Results. The patients were comparable in key paraclinical characteristics and comorbidity profile. One-year follow-up period revealed a significantly higher incidence of stroke, transient ischemic attack, myocardial infarction, and distal arterial embolism of lower limb arteries in subgroup B. With an increase in the maximum time between cardiac cycles in AF, an increase in hemodynamic parameters of arterial vessels occurred as both proximal and distal arteries. A similar trend was also observed in the analysis of arterial kinetic parameters.Conclusion. Not only the fact of AF presence is important for assessing the risk of arterial thromboembolism, but also its features. The most unfavorable for prognosis is AF with a maximum time between cardiac cycles ≥1,5 seconds. An increase in intra-arterial hemodynamic parameters after a long pause between ventricular contractions in AF without intracardiac thrombosis can become a key factor in the development of complications with existing plaques, which can become a source of distal embolism.

In Modular Automation, the orchestration creates the link between process equipment assemblies (PEA) and processes towards operation. This paper presents a general methodology, so-called type-based orchestration, on how to design a fully functional modular process plant based on the module type package (MTP). In a number of discussion rounds, the steps were identified, generalized, and formulated as a method. Existing standards were applied to describe additional required information. The resulting phases and steps, as well as the practical application, have shown that a large part of the planning can be done using only the type-information of planned modules. The type-based orchestration is later completed with instance information. The methodology was tested against a modular distillation plant from the Technical University of Dortmund.

Abstract
High-rate Global Navigation Satellite Systems (GNSS) observations from an integrated network in the Tibetan plateau were used for rapid source determination of the 2021 Mw 7.4 Maduo earthquake. Constrained by high-rate displacements from nine stations near the source, the magnitude was essentially determined as early as 20 s after the origin time (OT), whereas the 39-s-long rupture propagated only approximately halfway, and together with the epicenter location and rupture length, they were completely determined 29 s after the OT or 10 s before the rupture completion. In addition, to test the capability and feasibility of current GNSS networks for rapid source determination in the Tibetan plateau, two experiments were further implemented to invert source parameters by real observations at farther sites and synthetic observations induced by an Mw 7.0 modeled earthquake. The results demonstrate that current GNSS networks are capable and feasible to provide rapid source determination and earthquake early warning in approximately 30 s after the OT for large earthquakes (Mw 7.0+) based on current station density, spatial coverage and communication conditions in the Tibetan plateau.
