Towards the Customers' Intention to Use QR Codes in Mobile Payments
Authors: Chang Victor , Chen Waner , Xu Qianwen Ariel , Xiong Chang
Published: July 2021

This research studies the motivation of customers to choose the QR code as a payment tool by developing an integrated model based on UTAUT 424 valid responses were collected from diversified socio-economic backgrounds to validate the proposed framework. Compared with the original UTAUT model, the new one integrates ‘perceived security’, ‘perceived benefits’ and excludes ‘social influence’ to provide more comprehensive and consistent guidance. PLS-SEM technique was performed as in the data analysis process using SmartPLS. Our study concluded that seven of nine hypotheses are supported by the use of PLS-SEM technique. Customers' intention (R2=0.87) to use QR code as the payment tool is jointly contributed by their attitude, perceived usefulness, and subjective norms toward using QR code as the payment method. The formation of customers' attitudes (R2=0.79) towards using QR code is affected by their perceived usefulness, perceived benefits, and subjective norms. Discussion and strategies for the third parties of QR payment providers and future research directions are also presented.

Published: July 2021

Optimization of complex shrinkage-reducing additives (further, SRA’s), consisting of ordinary portland cement clinker (further, OPC clinker), salt-electrolyte and surfactants, is provided for prevention of steel reinforcement corrosion due to shrinkage mitigation in alkali-activated slag cement (further, AASC) fine concrete. Modification of AASC by SRA included 0.3 % sodium lignosulphonate, 0.15 % sodium gluconate, 1.4 – 2.0 % NaNO3 and 6.5 - 7.7 % OPC clinker (by mass of granulated blast furnace slag) provides shrinkage reduction from 0.984 up to 0.560 – 0.605 mm/m (t=202 °С, R.H.=65 %). Unlike, SRA presented by the mentioned system with 1.50 - 1.59 % Na2SO4 and 4.0 - 4.65 % OPC clinker causes shrinkage mitigation from down to 0.625 - 0.640 mm/m. In addition, SRA with 1.80 - 2.05 % Na3PO4 and 4.0 - 4.6 % OPC clinker minimizes shrinkage to 0.713 - 0.700 mm/m. Shrinkage mitigation in modified AASC fine concrete is explained by less water, higher crystallinity of hydrated phases as well as by formation of minamiit (Na,Ca0.5)Al3(SO4)2(OH)6, calcium hydronitroaluminate ЗСаО∙А12О3∙Са (NO3)2∙10Н2О and calcium hydroxylapatite Са10(РО4)6(ОН)2 crystals versus salt-electrolyte, i.e. Na2SO4, NaNO3 and Na3PO4 agreeably. The 28 day compressive strength of modified AASC fine concrete is not less than the reference one (48.0 - 56.0 МPа).

Published: July 2021

Practical work and is devoted to the study of the rheological and deformative properties of Geofip aluminosilicate glue, obtained on the basis of an alkaline aluminosilicate binder composition Na2O Al2O3×6SiO2×20H2O, modified with 5% Cr2O3, when gluing wooden trusses in the field. The rheological and deformative properties of an aluminosilicate adhesive based on an alkaline aluminosilicate binder composition of Na2O×Al2O3×6SiO2×20H2O modified with 5% Cr2O3 have been investigated. It is noted that the dynamic viscosity of the adhesive slurry in the speed range from 0.1 to 0.8 RPM varies from 147600 to 144600 cP, and the average plastic viscosity in the same speed range is 87.39 cP. It was found that at shear rates from 0.021 to 0.168 1/s, an increase in shear force from 31 to 242.9 dyne/cm2 is observed due to the stabilization and uniformity of the dispersion phase particle distribution in the dispersion medium of the adhesive. It is shown that the aluminosilicate adhesive at a surface tension value of 88.1 mN/m is characterized by coefficients of wetting (s = 0.648) and fluidity (f = -62.02 mN/m), which ensures the uniformity of its application to the pine substrate. The average thickness of the adhesive layer was 1.25 mm, and the average depth of penetration of the aluminosilicate adhesive into the wood substrate, respectively, 0.12 mm. The destruction of the adhesive seam occurred at shear stresses of 515 MPa. The relative shear deformations were 162.5×10-5 mm.

Published: July 2021

Cartilaginous fish, or Chondrichthyes, are the oldest extant vertebrates to possess the MHC and the Ig superfamily–based Ag receptors, the defining genes of the gnathostome adaptive immune system. In this work, we have identified a novel MHC lineage, UEA, a complex multigene nonclassical class I family found in sharks (division Selachii) but not detected in chimaeras (subclass Holocephali) or rays (division Batoidea). This new lineage is distantly related to the previously reported nonclassical class I lineage UCA, which appears to be present only in dogfish sharks (order Squaliformes). UEA lacks conservation of the nine invariant residues in the peptide (ligand)–binding regions (PBR) that bind to the N and C termini of bound peptide in most vertebrate classical class I proteins, which are replaced by relatively hydrophobic residues compared with the classical UAA. In fact, UEA and UCA proteins have the most hydrophobic-predicted PBR of all identified chondrichthyan class I molecules. UEA genes detected in the whale shark and bamboo shark genome projects are MHC linked. Consistent with UEA comprising a very large gene family, we detected weak expression in different tissues of the nurse shark via Northern blotting and RNA sequencing. UEA genes fall into three sublineages with unique characteristics in the PBR. UEA shares structural and genetic features with certain nonclassical class I genes in other vertebrates, such as the highly complex XNC nonclassical class I genes in Xenopus, and we anticipate that each shark gene, or at least each sublineage, will have a unique function, perhaps in bacterial defense.
Protein Kinase CK2 Regulates B Cell Development and Differentiation
Authors: Wei Hairong , Yang Wei , Hong Huixian , Yan Zhaoqi , Qin Hongwei , Benveniste Etty N
Published: July 2021

Protein kinase CK2 (also known as Casein Kinase 2) is a serine/threonine kinase composed of two catalytic subunits (CK2α and/or CK2α′) and two regulatory CK2β subunits. CK2 is overexpressed and overactive in B cell acute lymphoblastic leukemia and diffuse large B cell lymphomas, leading to inappropriate activation of the NF-κB, JAK/STAT, and PI3K/AKT/mTOR signaling pathways and tumor growth. However, whether CK2 regulates normal B cell development and differentiation is not known. We generated mice lacking CK2α specifically in B cells (using CD19-driven Cre recombinase). These mice exhibited cell-intrinsic expansion of marginal zone B cells at the expense of transitional B cells, without changes in follicular B cells. Transitional B cells required CK2α to maintain adequate BCR signaling. In the absence of CK2α, reduced BCR signaling and elevated Notch2 signaling activation increased marginal zone B cell differentiation. Our results identify a previously unrecognized function for CK2α in B cell development and differentiation.

Published: July 2021

Seven hundred sixty-five (765) adult wild boars were examined during the 2016/2017 hunting season for the research of parasites. Post mortem inspection was carried out at the slaughterhouse by the Official Veterinarian on the plucks (heart, tongue, lungs, diaphragm, and liver) of the killed animals presented by hunters. Of these, 0.8% (6/765) were positive for Echinococcus granulosus sensu lato (s.l.), and 2.6% (20/765) were positive for the metacestode stage of Taenia hydatigena (Cysticercus tenuicollis), while 0.5% (4/765) animals showed a mixed infection (Echinococcus granulosus s.l. and Taenia hydatigena). Sixty-three (63) cystic lesions were found. Of these 25,4% (16/63) were caused by Echinococcus granulosus s.l. and 74,6% (47/63) were caused by Cysticercus tenuicollis. The more involved organs were liver and lungs, in a less extension omentum and diaphragm. Parasitological analyses showed an overall prevalence of 3.9% for metacestodes in the hunted animals examined (Paoletti et al., 2018). Hydatids were molecularly characterized as E. granulosus sensu stricto. Trichinella spp. examination results showed no evidences of parasitic cysts. The products of hunting used for own consumption and direct sale to the final consumer or retailer, according to Regulation (EC) No 853/2004, lack of overall control by the Competent Authority. This is a critical point in the food chain of the game meat. The data obtained show the importance of the post mortem inspection and the central role of the Competent Authority to ensure not only the food safety of game meat but also to collect data for extensive epidemiological investigations on live-stocks wildlife settings having a direct impact on public health.

Published: July 2021

A monazite sample extracted from Western Australia mineral sands has been characterized. The monazite in powder form, was injected into the Long-Lived Radioactive Dust Test Facility (LLRDTF) at the Elliot Lake Laboratory. The LLRDTF is a multi-purpose
experimental facility designed, among other things, for the evaluation of radioactive dust instrumentation and the characterization of Long-Lived Radioactive Dust (LLRD). The following characteristics of the monazite sample were measured: dust mass versus particle size, alpha-particle activity
versus particle size, radionuclide composition, electrical charge versus particle size, and 222Rn and 220Rn emanation from the sample. Cascade impactors were used for particle size and long-lived radioactivity characterization. Alpha- and gamma-spectrometry were employed for radionuclide
identification. Special methods were used to measure the emanation of 222Rn and 220Rn from the monazite sample. The data obtained is of interest for dose estimation calculation purposes in the mineral sands industry.
Use of Intraoral Three-Dimensional Images for the Identification of Dental Morphological Traits Related to Ancestry Estimation

Published: July 2021

Victim identification through dental features is one of the main objectives of forensic dentistry. In circumstances where information regarding antemortem dental records is missing, reconstruction of a biological profile can be useful as a first step toward personal identification. This reconstructive method provides valuable information, namely regarding the individual's ancestry, through the detection and degree of expression of dental morphological traits, which may help to restrict the number of candidates for identification. Technological advances allowed the development of alternative methods for dental evaluation, that complement or substitute those already in use in clinical practice. Among these, intraoral three-dimensional (3D) images are increasingly used in dentistry, as they have a high level of accuracy and are easy to obtain and store. However, a fundamental question regarding forensic dentistry is whether they allow recognition and analysis of dental morphological traits in detail, namely those related to ancestry. In this study, we evaluated 20 teeth morphological features using intraoral 3D imaging from 77 individuals from Northern Portugal. Our results showed that it was possible to identify and classify a large part of the main morphological traits used in the estimation of ancestry. As these 3D images present sufficient morphological detail to be classified, we believe that future applications of this technique can be expected in forensic dentistry.

Published: July 2021

Complex kinship identification such as half-sibling identification is a difficult task in forensic biology Here we represented an approach in dealing with half-sisters from different mothers, with the combination of autosomal and X chromosomal short-tandem repeats (STRs) data. X chromosomal STRs can offer additional information, especially in some cases where autosomal STRs alone may not provide enough information for an accurate opinion. In this case, half-sister or unrelated relationship between two women (S1 and S2) with different mothers were distinguished. 23 autosomal and 31 X chromosomal STRs of S1, S2, S1's mother (M1), S2's mother (M2) and S1's grandmother (G1) were profiled with three different commercial kits. As to X-chromosome STRs, likelihood ratios (LRs) were calculated by FamLinkX with consideration of linkage, linkage disequilibrium, and mutations. When only the profiles of the two individuals (S1 and S2) were available, LRs between S1 and S2 were 1.1110 × 102 based on 23 autosomal STRs and 3.2257 om107 based on 31 X chromosomal STRs. When the maternal genotypes were taken into consideration, LRs increased to 2.5297 × 103 and 3.0563 × 1018. Therefore, both the DNA profiles of each mothers and X chromosomal STRs are important in dealing with the identification of half-sisters from different mothers.
British Rhinological Society audit of the role of antibiotics in complications of acute rhinosinusitis: a national prospective audit
Authors: Babar-Craig H. , Gupta Y. , Lund V.J.
Published: July 2021

Objective: Acute rhinosinusitis (ARS) is one of the most common presenting conditions to Primary Care physicians. Over-prescription of antibiotics has led to wide debate and divided expert opinion regarding the resulting increasing bacterial resistance or the merits of prevention of more serious complications of ARS. A national prospective audit was undertaken in the UK to evaluate use of antibiotics for ARS in Primary Care. Methods and materials: British Rhinological Society members were asked to contribute patients admitted with complications of ARS, between Feb 2008–Feb 2009 to a national prospective audit via an on-line survey. Results: Seventy-eight patients were admitted with complications of ARS. The majority of patients were started on antibiotics (59%) prior to admission, with penicillin/amoxicillin being most frequently (64%) prescribed. Similar complication rates were seen in patients treated with and without prior antibiotics. Conclusion: Despite prior antibiotic treatment, complications of ARS seem to occur sporadically. Our study has shown that the complications which require surgical treatment are similar in both the prior antibiotic treated group and the no prior antibiotic group, suggesting limited benefit of oral antibiotics in the Primary Care setting. Early recognition with CT scanning and appropriate hospital management is essential to reduce any subsequent morbidity or mortality.
Reference values for acoustic rhinometry in children at baseline and after decongestion
Authors: Haavisto L.E. , Vahlberg T.J. , Sipila J.I.
Published: July 2021

Background: Acoustic rhinometry is widely used for objective evaluation of nasal dimensions. However, there is a lack of agreement on the normative values in children at baseline, and especially after decongestion. The purpose of this study was to determine the reference values for Finnish school children for acoustic rhinometry in non-decongested and decongested noses, and to find out which of the potential predictors (age, sex, body surface area (BSA) and height) would be the most useful one(s). Methodology: The study included 124 children aged between 6.90 and 13.84 years with no permanent nasal symptoms. Results: At baseline, the mean total minimal cross-sectional area (MCA) was 0.752 cm2, and the mean total volume between 0 - 3 cm (VOL) was 4.00 cm3. After decongestion, the total MCA was 0.794 cm2, and the VOL was 4.38 cm3. There was a significant correlation between MCA and age, between VOL and height, and between VOL and BSA at baseline and after decongestion. We found no difference in the values between boys and girls. Conclusions: We conclude that acoustic rhinometry is a suitable objective method to monitor the changes in mucosal swelling and nasal obstruction in children. Age and height or BSA of a child can be suggested as predictive factors.

Hans Zenders abendfüllendes Werk Shir hashirim lässt sich als ein Komplex mehrerer, außerordentlich differenzierter Lesarten des Hoheliedes interpretieren. Dabei bilden textliche und musikalische Kohärenz (im Sinne syntaktischer und intertextueller Bezugsfelder) eine ebenso wichtige Rolle wie deren Sprengung durch die Aufsplitterung von Worten und Textteilen und die Exponierung von primär klanglicher und lautsprachlicher Sonanz.

Invisible Conflicts: The Challenges of Design on a Planetary Scale
Authors: Brusadin Bani , Benítez Valero Laura
Published: July 2021

The experience of the interconnected planet is the experience of an artificial totality, the result of the accelerated intersection of different invisible realms, topologies and layers that compete with one another following the irregular logics of rival interests, incompatible designs, non-human life form habits and rhythms, forms of resistance, errors, collateral effects and accidents. This issue of Temes de Disseny presents case studies and research practices that address the need to focus on these frictions from a variety of different perspectives in order to detect new forms of power and hidden inequalities as well as to envision unprecedented opportunities for intervention and counter-design.

PURPOSE: Radical prostatectomy (RP) is the gold standard treatment option for localized prostate cancer (Pca) treatment. In this study, we aimed to evaluate the potance condition of patients who completed the first year after the radical prostatectomy operation with the perineal approach . PATİENTS AND METHODS: The study included 107 preoperatively potant patients who underwent RPP for localized PCA between April 2006 and September 2009. Besides to 65 patients with a preoperative International Index of Erectile Function (IIEF)- 5 score of 21 or over, 42 patients who were evaluated with their partners, even though whose preopeative IIEF-5 score was between 16-20; however, answered yes to the SEP 2 and SEP 3 questions, were considered as potant. RESULTS: The mean age of the patients was 62.4 years. The mean preoperative PSA value was 6.5 ng/dL. The mean prostate volume was 48cc (15-70). Eighty-one (75.7%) of all patients were able to continue their sexual life with or without medication at postoperative 12th month. Forty-four (54.3%) patients were normal in terms of sexual function without any need for additional treatment CONCLUSİON: We evaluated that erectile function was preserved in 81 of 107 (75.7%) patients after 1 year from surgery with or without medical therapy.

Published: July 2021

Aim: This study aims to investigate surgical nurses’ cigarette use, their nicotine dependence levels, and the affecting factors. Material and Methods: This descriptive and correlational research was carried out in a university hospital with the participation of nurses (n = 108) who work in surgical units and smoke. The data were collected with a Personal Information Form, Smoking Information Form, and the Fagerström Test for Nicotine Dependence. SPSS for IBM 25 was used for statistical analysis. Descriptive statistics, independent t-test, one-way variance and regression analysis, and the Bonferroni test were used in the analysis of the data. Results: The results were evaluated at a 95% confidence interval and p <0.05 significance level. 34% of surgical nurses were between 21-29 years old, 65% were women, 58% were single, and 86% had bachelor degrees. 65% of the nurses were smoking due to stress, 53% due to enjoyment, and 80% were smoking more than 10 cigarettes per day. It was found that the nurses working in the intensive care unit smoked more cigarettes than the operating room and service nurses. Conclusion: As a result of this research, it was found that surgical nurses had a high level of nicotine dependence. Strategies for surgical nurses to quit smoking should be developed and training should be provided.

Congenital diaphragmatic hernia is one of the rare malformations (0.8-5 / 10000). Although there are many treatment options in the postnatal period, as the severity of the malformation increases, the response to treatment decreases. Lung development is restricted by the compression of intraabdominal organs passing through the diaphragmatic defect. The severity of pulmonary hypertension due to hypoplasia in the lung tissue is closely related to postnatal morbidity and mortality. In addition to the lung tissue, left ventricular hypoplasia may also occur due to pressure on the heart. For all these reasons, treatment options have begun to be investigated even in the prenatal period, before tissue hypoplasia develops. In the last 20 years, there have been serious developments in ultrasound and magnetic resonance devices in parallel with the developments in technology. Accordingly, lung development of fetuses with diaphragmatic hernia during prenatal period has been better followed. Fetal endoscopic tracheal occlusion is the only method that can give treatment options to patients who are found to have severely decreased lung tissue in the prenatal period, in order to increase postpartum life expectancy. With this procedure, it is aimed to collect the fluids released from the lung with a balloon placed in the trachea in the prenatal period. Because of these accumulated fluids, the lung volume expands, tissue hypoplasia decreases, and the degree of pulmonary hypertension decreases. Although the fetal tracheal occlusion procedure has improved neonatal outcomes, there is a possibility of complications depending on the way the procedure is applied. Various complications such as premature rupture of membranes and preterm labor can be seen depending on the procedure. For this reason, it is necessary to choose the candidates for the tracheal occlusion procedure well and to calculate the profit-loss ratio well. In this study, current publications of fetal endoscopic tracheal occlusion procedure were reviewed. It was investigated on which patients the procedure could be applied and what the benefits and harms might be if it was applied.
Методичний підхід до кількісного оцінювання спроможностей медичних підрозділів Збройних Сил України
Authors: Zui Y. O.
Published: July 2021

Вступ. У статті запропоновано методичний підхід до модульного кількісного оцінювання спроможностей медичних підрозділів Збройних Сил України, в основу якого покладено модульний підхід до побудови та оцінювання медичних підрозділів, що застосовується у Північноатлантичному Альянсі. Аналіз затверджених методів оцінювання спроможностей дозволив зробити висновки про необхідність розробки та впровадження до практики ЗС України модульного оцінювання функціонування медичних підрозділів з використанням принципів багатокритеріальної оптимізації.

Мета. Розробити можливі підходи до кількісного оцінювання спроможностей медичних підрозділів ЗС України та їх функціональних модулів.

Матеріали та методи. Бібліосемантичний, системного аналізу та підходу, концептуального моделювання, медико-статистичний.

Результати. Мета медичного забезпечення збройних сил досягається виконанням сукупності завдань для вирішення яких існують медичні підрозділи, заклади та керівні медичні органи. Постає необхідність визначення таких завдань, які були б реальні для виконання в умовах впливу зовнішніх та внутрішніх факторів, та з іншої сторони – забезпечували необхідний рівень надання медичного забезпечення основних сил. Оскільки медичне забезпечення є багатокомпонентною системою з безліччю критеріїв та показників, постає проблема в об’єктивному порівнянні рівня набутих медичними підрозділами спроможностей з необхідними. Практика країн, що запровадили на державному рівні оборонне планування на основі спроможностей, показує, що стандартизація модульної побудови медичних підрозділів збройних сил та оцінювання спроможностей за елементами системи DOTMLPF-I забезпечує високу готовність підрозділів, більш ефективну та гнучку роботу під час виконання покладених на них завдань. Якісне, обґрунтоване та стандартизоване оцінювання спроможностей дасть змогу виявляти ризики, мінімізувати суб’єктивне тлумачення вимог до спроможностей та наблизити функціональну, організаційну та ресурсну сумісність медичних підрозділів Сил оборони України та Північноатлантичного альянсу. Зазначене вище актуалізує необхідність розробки методології оцінювання спроможностей медичних підрозділів ЗС України наближеної до стандартів НАТО.

Висновки. Незважаючи на те, що у ЗС України вже багато років триває робота стосовно набуття взаємосумісності з державами‐членами НАТО, розробки доктрини з оцінювання та методичних рекомендацій з оцінювання (сертифікації), дослідження питань оборонного планування на основі спроможностей та проблем оцінки спроможностей досліджена недостатньо. Робота з розробки методів оцінювання спроможностей медичних підрозділів триває і досі. В результаті системного аналізу виявлено значні відмінності в рівнях оцінювання спроможностей медичного забезпечення збройних сил, функціональній побудові медичних підрозділів та розбіжності в критеріях оцінювання спроможностей, що дозволяє запропонувати методичний підхід щодо оцінювання.

Вступ. Дефіцит заліза (ДЗ) є серйозною проблемою у жінок віком 40-55 років. В цей період відбувається варіації гормональних рівнів, порушення менструального циклу з ризиком виникнення тяжкої крововтрати. Крім того, жінки цієї вікової групи часто ведуть нездоровий спосіб життя, з наступним розвитком порушень, що призводять до змін у фізичному і психічному станах.

Мета роботи. Дослідити причини розвитку ЗДА у жінок, які знаходилися під спостереженням у клініці гематології Національного військового медичного клінічного центру «Головний військовий клінічний госпіталь» МО України і визначити фактори  ризику розвитку анемії та її корекції.

Матеріали та методи. У статті надані дані європейських досліджень про високий ризик розвитку дефіциту заліза/залізодефіцитної анемії (ДЗ/ЗДА) у жінок віком 40-55 років. Проведений аналіз обстеження та лікування 109 жінок, котрі знаходилися під спостереженням у клініці гематології Національного військово‐медичному клінічному центрі «ГВКГ» (м. Київ) з 2015 по 2019 роки.

Результати. Узагальнено сучасні наукові  європейські дослідження щодо ризику розвитку ДЗ/ЗДА у жінок віком 40-55 років. Проведено аналіз причин розвитку ЗД/ЗДА за результатами обстеження та лікування жінок, котрі знаходилися під спостереженням у клініці гематології Національного військово‐медичному клінічному центрі «ГВКГ» (м. Київ) з 2015 по 2019 роки. Виділено найбільш часті причини розвитку ЗД/ЗДА: рясні менструальні крововтрати, запальні процеси в органах шлунково-кишкового тракту, зниження вживання м'ясних продуктів, прийоми антикоагулянтів, порушення дієти з метою схуднення, що в цілому складає 75% серед можливих причин.

Висновки. За даними  європейських досліджень виявлено високий ризик розвитку ДЗ/ЗДА у жінок віком 40-55 років при цьому клінічні прояви ЗДА у жінок віком 40-55 років є проблемою суспільної охорони здоров’я, оскільки призводить не тільки до зниження працездатності, але й до зниження якості життя жінок.  Результати проведених досліджень свідчать про багатофакторну структуру причин розвитку ДЗ у жінок віком 40-55 років, головними з яких є рясні менструальні крововтрати (21,1%), запальні процеси в органах шлунково-кишкового тракту (19,26%), зниження вживання м'ясних продуктів (13,76%), прийоми антикоагулянтів (10,1%). Показано, що визначення факторів ризику розвитку анемії і корекції цих негативних проявів за допомогою препаратів заліза є актуальним завданням для лікаря.

The article raises the question of the strange behavior of electrons in an atom, when the electronic orbitals of the P- and d-states of the atom have the form of eights with nodal points in the nucleus of the atom, as well as the discovery of the mysterious K-capture of an electron when the nuclei of atoms of some isotopes of chemical elements someh they sometimes capture an electron from the inner (K- or L-) electron shell of the atom. It has not been possible to explain these phenomena within the framework of the atomic model existing in quantum electrodynamics. In the new model of the atom, proposed by Professor Lev Sapogin in Unitary Quantum Theory, the electron makes quantum leaps within the orbital not randomly, as physicists thought, but through the nucleus of the atom, each time tunneling through it. In this case, the quantization of the energy levels (orbitals) of electrons in an atom is explained by the distribution of nodes and antinodes in a standing wave of an electron, and an integer number of de Broglie wavelengths should be located in the diameter of the electron orbital. The article shows the dependence of the magnitude of the interaction constants in the hydrogen nucleus and, in particular, the fine structure constant, discovered by the CMS cooperation in experiments at the Large Hadron Collider in 2019, during reactions in pp collisions with energies from 1 TeV to 13 TeV and an intranuclear pressure of 10³⁵ Pascal. The value of the fine structure in the near-Earth medium and in a neutron star is given

With the help of a special algorithm being the principle of multilevel periodicity, the periodic change of properties at the nuclear level of chemical elements was discovered and the variant for the periodic system of isotopes was presented. The periodic change in the properties of isotopes, as well as the vertical symmetry of subgroups, was checked for consistency in accordance with the following ten types of the experimental data: mass ratio of fission fragments; quadrupole moment values; magnetic moment; lifetime of radioactive isotopes; neutron scattering; thermal neutron radiative capture cross-sections (n, γ); α-particle yield cross-sections (n, α); isotope abundance on Earth, in the Solar system and other stellar systems; features of ore formation and stellar evolution. For all the ten cases, the correspondences for the proposed periodic structure of the nucleus were obtained. The system was formed in the usual 2D table, similar to the periodic system of elements, and the mass series of isotopes was divided into 8 periods and 4 types of “nuclear” orbitals: sn, dn, pn, fn. The origin of "magic" numbers as a set of filled charge shells of the nucleus was explained. Due to the isotope system, the periodic structure is shown at a new level of the universe and the prospects of its practical use are opened up

La devastación de la vida en tiempos del Covid-19 o Coronaceno está antecedida por un conjunto de catástrofes, tragedias y calamidades que, desde Chile, requieren una reflexión antropológica para analizar su despliegue. La crisis ambiental a escala global ha deteriorado el devenir de la vida en los territorios y la manifestación local de la pandemia da cuenta de ello. En el presente artículo analizamos a la devastación en su dimensión territorial, para así reflexionar sobre el despliegue del Coronaceno en Chile en que se visibilizan siniestros normativos y futuros posibles que emergen de las decisiones comunitarias para amortiguar las consecuencias de la pandemia del Covid-19 en sus territorios. La devastación da cuenta de un escenario de catástrofe que ha sido provocado conscientemente y asumiendo las consecuencias. Por tanto, proponemos que la devastación es resultado decisional de la acción humana a sabiendas de que deteriora casi irreversiblemente las condiciones de vida, incluso aquellas que permiten revertir la situación. El despliegue del Coronaceno en Chile es fecundo para aproximarnos a estas reflexiones durante la devastación.

Introduction. According to epidemiological observations, the level of congenital malformations in children is associated with the degree of chemical pollution of the environment and certain forms of genes of the I and II phases of the xenobiotic biotransformation system. The study aimed to determine and compare the index of anthropogenic load with the probability of occurrence of congenital malformations of the fetus in combination with gene polymorphisms of I and II phases of the xenobiotic biotransformation system in women living in different administrative territories in the South of Kuzbass. Material and methods. The level of air pollution in the cities of the South of the Kemerovo region (Kuzbass) was established. Prenatal screening of 1,426 pregnant women at the term of 15-18 weeks in the cities of the South of Kuzbass was carried out. The Real Time-PCR method was used to determine the gene polymorphism of the xenobiotic biotransformation system (CYP1A2, GSTM1) in 53 women of Novokuznetsk who gave birth to newborns with congenital malformations. Results. In the cities of the South of Kuzbass, with a critical and high degree of pollution of atmospheric air and waterways, many women are at risk of congenital malformations in offsprings. The A/A CYP1A2*1F genotype in combination with the deletion polymorphism of the GSTM1 gene in the mother is reliably associated with the occurrence of congenital malformations in offsprings (χ2 - 4.72; р - 0.030; OR - 5.56; CI - 1.05-29.32), and the C/ACYP1A2*1F genotype in combination with the normal functioning GSTM1 “+” gene is associated with resistance to the development of congenital malformations (χ2 - 12.53; p - <0.001; OR - 0.11; CI - 0.03-0.4 ). Conclusion. Against the background of an increasingly unfavourable ecological situation in Kuzbass and raising the number of newborns with congenital malformations, it is essential to include in the algorithm for early prenatal diagnosis the determination of the forms of genes of different phases of the xenobiotic metabolism system to elaborate an algorithm for reducing the xenobiotic load on the body of pregnant women during critical periods of fetal organogenesis.
