KINETIC ISOTOPIC EFFECT: STATIC RAYLEIGH EQUATION AND BASIC DYNAMIC ISOTOPE EQUATION FOR THE SUBSTRATE IN THE DESCRIPTION OF NITRITE-DEPENDENT ANAEROBIC OXIDATION OF METHANE
Authors: Vavilin Vasiliy Aleksandrovich
Published: December 2021

The article analyzes the results of modeling the dynamics of nitrite-dependent methane oxidation (N-DAMO) by Methylomirabilis oxyfera microorganisms using the standard isotope dynamic equations. Without specifying a specific function of the rate of the process, the traditional static Rayleigh equation is derived from the basic dynamic isotope equation. Thus, the equation of the 1st order in terms of the substrate is only a special case in the derivation of the Rayleigh equation. It was shown that the dominant fractionation of carbon isotopes occurs in the process of the microbiological reaction of anaerobic oxidation of methane by nitrite, and not in the physical process of mass transfer of dissolved methane into the gas phase. In contrast to the static Rayleigh equation, the dynamic description of the process of fractionation of stable isotopes is important when describing the parallel transformations of the substrate.

Authors: Kong Fanting , He Chenxi , Kong Fanlei , Zhao Wei , Han Sufen , Yang Lixian
Published: December 2021

To explore the application effect of MRI and miR-134 in neo-adjuvant chemotherapy combined with breast-conserving surgery. Sixty-one patients who received neo-adjuvant chemotherapy combined with breast-conserving surgery were collected as observation group (OG), and other 53 patients
who received breast-conserving surgery at the same time were collected as control group (CG). The positive surgical margins rate, axillary lymph node metastasis rate, 5-year survival rate, recurrence rate and miR-134 expression before and after treatment were compared between the two groups.
The diagnostic ability of MRI and miR-134 before treatment for axillary lymph node metastasis and the prognostic significance of miR-134 after treatment were explored. The positive surgical margins rate in OG was obviously lower than that in CG. There was no significant difference in axillary
lymph node metastasis rate. There was no obvious difference in 5-year survival rate in both groups. The 5-year recurrence rate in OG was obviously lower than that in CG. Before therapy, the area under ROC curve (AUC) of miR-134 in diagnosing axillary lymph node metastasis was 0.788, and the
specificity and sensitivity were 70.59% and 86.25%. The specificity and sensitivity of MRI diagnosis were 90.00% and 76.47%, and the combined diagnosis was 63.75% and 97.06%, so the sensitivity was improved. After treatment, the AUC of miR-134 in predicting 5-year survival was 0.810, and that
of miR-134 in predicting 5-year recurrence was 0.767. To sum up, neo-adjuvant chemotherapy combined with breast-conserving surgery can decline the postoperative recurrence rate of patients. Preoperative miR-134 combined with MRI can diagnose axillary lymph node metastasis, and preoperative
miR-134 can predict the prognosis.

Published: December 2021

To study the effect of cluster nursing model combined with psychological intervention on emotional control and life quality of patients with continuous blood purification (CBP) and catheter-related bloodstream infection (CRBSI). 126 patients with CBP catheterization treated in our
hospital (November 2018-November 2019) were chosen as the study subjects, and randomly split into group A and group B, 63 cases in each group. Group B adopted routine nursing while group A received cluster nursing model with psychological intervention to compare the emotional control level
and life quality between the two groups. No obvious differences in sex ratio, age, BMI, smoking history, drinking history, marital status, disease types, catheter indwelling time and catheter position were found between the two groups(P>0.05). After nursing intervention, MPV and CD62-P
in group A were obviously lower while PLT value was obviously higher compared with group B (P<0.001). CRBSI occurred later in group A compared with group B after intervention (P<0.001), and CRBSI duration was shorter compared with group B (P<0.001). The CECS scores in both groups
after intervention were obviously higher, and CECS score in group A after nursing intervention was obviously higher compared with group B(P<0.001). SF-36 scores in both groups after nursing intervention were obviously higher, and SF-36 score in group A after intervention was higher compared
with group B (P<0.001). The total nursing satisfaction in group A was obviously higher compared with group B (P<0.05). Cluster nursing model combined with psychological intervention can enhance emotional control level of patients with CBP catheterization, shorten the CRBSI duration,
improve the life quality and nursing satisfaction, with obvious effect, deserving reference and promotion.

Authors: Chen Yueyao , Li Haixiang , Chen Chaoqin
Published: December 2021

Objective: This research was designed to probe into the effects of Dapagliflozin on renal interstitial fibrosis in diabetic rats through Smad3, TIMP1 and MMP24 pathway. Methods: Rats were bought to establish models, and then intervened by Dapagliflozin. Human mesangial cell lines
(HMCs) stimulated by high glucose were purchased, and the Smad3, TIMP1 and MMP24 levels in rats after modeling and Dapagliflozin intervention were detected. The Smad3, TIMP1 and MMP24 protein expression in kidney tissue was examined after the rats were killed, and the expression in an intervention
group (IG) and a blank group (BG) were analyzed. The cells were divided into three groups: Dapagliflozin intervention (Group 1), TGF-P1/Smad3 pathway inhibitor SIS3 intervention (Group 2) and no intervention (Group 3). The TIMP1 and MMP24 levels were assessed. Results: The Smad3 and MMP24
levels in group A were higher than those in other two groups (p < 0.05), while those of TIMP1 were lower (p < 0.05). Compared with pre-intervention, the Smad3 and MMP24 levels in groups A and B decreased (p < 0.05), while those of TIMP1 increased (p < 0.05). The Smad3 and MMP24
protein levels in groups A and B were higher than those in other two groups (p < 0.05), while those of TIMP1 was lower (p < 0.05). Compared with the BG, the Smad3 and MMP24 expression in the IG was lower (p < 0.05) and that of TIMP1 was higher (p < 0.05). The TIMP1 expression in
Group 3 was lower (p < 0.05) and that of MMP24 was higher than those in Groups 1 and 2 (p < 0.05). Conclusion: Dapagliflozin can treat diabetic renal interstitial fibrosis by inhibiting TGF-P1/Smad3 signaling pathway, decreasing MMP24 and increasing TIMP1.

Published: December 2021

Objective. To explore the effect of different doses of propofol and nerve block combined with general anesthesia on the intraoperative anesthesia and postoperative awakening and cognitive function in elder patients with knee osteoarthritis (OA). Methods. According to the inclusion
criteria for research object, we selected 98 elderly patients with knee OA who needed surgery and were admitted to our hospital from January 2019 to January 2021 for the study. Patients were divided into the low dose group (given 2 mg/kg propofol by pumping under constant speed during surgery)
and the high dose group (given 4 mg/kg propofol by pumping during surgery) by the number table method to compare their indicators including the intraoperative anesthesia effect, with 49 cases in each group. Results. No between-group difference was shown in the anesthesia time and postoperative
VAS scores, but the awakening time of the low dose group was significantly shorter than that of the high dose group (P<0.05); the differences in heart rate (HR) values at various time points between the two groups were not obvious, but the high dose group obtained significantly higher HR
values at T4 than the low dose group; the mean arterial pressure (MAP) values of both groups were significantly reduced at Ti and then returned to the level before anesthesia (P>0.05); the bispectral index scores (BIS) of both groups experienced a marked drop at Ti and then recovered gradually,
but failed to return to the level at T0 till the end, and a between-group difference in BIS indexes presented at Ti; the plasma corticosterone (CORT) concentration at Ti of both groups were significantly lowered and then returned to the level at T0, with no between-group difference; and compared
with the low dose group, the high dose group achieved slightly lower mini-mental state examination (MMSE) scores at 24-72 h after surgery, with no significant difference between them (P>0.05). Conclusion. The therapy of different doses of propofol and nerve block combined with general anesthesia
has no significant effect on the cognitive function in elderly knee OA patients after surgery. With the nerve block improving the analgesic effect, a low dose of propofol is good for the postoperative awakening of patients. Different doses of propofol inhibited the stress response to a different
degree and produced good anesthesia outcomes in elderly patients, but comparatively speaking, a low-dose propofol ensures more smooth indexes and less effect on the intraoperative hemodynamics.

Customized protocol for psychological management of a patient with residual maxillofacial defects
Authors: Prakash Poonam , Bahri Rahul , Bhandari SK
Published: December 2021

: Maxillofacial surgeons and Prosthodontist deal with rehabilitation of defects of orofacial region but understanding the mental attitude of patients is often ignored or neglected. Success of any prosthesis relies on patient’s compliance and motivation to adjust and cope up with irreversible loss. Evaluation of psychological distress and management of the same is of utmost importance. Literature is deficit with an elaborate systematic classification system to evaluate the impact of maxillofacial defect on the psychological status of patients and role of therapy on improvement post-rehabilitation.

: Am of this study is to propose a customized comprehensive protocol for evaluation of psychological status using ICD-11 classification system before and after maxillofacial prosthetic intervention and impact of psychological management tools on the same.

: Ten patients with maxillofacial defects reporting for prosthetic rehabilitation were selected. Psychological evaluation tool, ICD-11 classification system was applied pre and post rehabilitation by two independent observers. Customized psychological management protocol was formulated and implemented to note the impact on overall improvement in psychological status of the patient.

: Patients with severe personality trait showed varied levels of improvement ranging from no change to mild. Five patients with moderate personality trait showed improvement and change in personality trait to mild on implementation of psychological tools. Statistical evaluation could not be done due to multitude of subjective variables.

: ICD-11 can be used as a successful tool for psychological evaluation of patients. Necessary intervention at every level in form of family support, support groups, psychological therapeutic modalities and therapies can improve status of the patient. A well-structured management protocol helps in early recognition of psychological distress and systematic management of the same to improve clinical outcome of the rehabilitation procedure.

: Patients with maxillofacial defects experience a progressive cycle of loss and grief. This diminishes their ability to adjust to stress and acceptability towards maxillofacial prosthetic rehabilitation procedure. Assessment of psychological alteration using a standardized classification system and utilization of therapeutic modalities to deal with the same helps in successful rehabilitation and restoration of patient in the society as a whole.

This case report describes a treatment option for the replacement of a missing maxillary central incisor using a double-retainer resin-bonded fixed partial denture (RBFPD), fabricated from zirconium dioxide (ZrO) ceramic. No clinical complications were observed at follow-up examination after placement of the prosthesis. Satisfactory functional and aesthetic results were achieved. A treatment modality using a ZrO ceramic RBFPD is an alternative for single anterior tooth replacement.
Oxidation Characteristics of Water Soluble Fractions of Agro-Stalks with Focus on Function of Reactive Inorganics
Authors: Zhao R. , He F. , Behrendt F. , Cai J. , Dieguez-Alonso A. , Liu Y.
Published: December 2021

In order to deepen the understanding of the thermochemical behavior of reactive inorganics, which play an important role in slagging and fouling during combustion of agro-stalks, the oxidation behavior of the water-soluble fraction of corn stover, wheat straw and rice straw was examined using a simultaneous thermogravimetric analyzer. The oxidation characteristics were discussed in combination with elemental analysis of water-soluble fractions. Results showed that reactive inorganics elements account for 30–40% in water-soluble fractions of the three agro-stalks and carbon was oxidized at two separate stages. Four stages were found during oxidation of water-soluble fractions – (1) devolatilisation of organics (100‒400 °C); (2) oxidation of char (400–650 °C); (3) oxidation of char with melting of salts or decomposition of carbonate (650–800 °C); (4) vaporization of KCl (800–1000 °C). This work provides a base study for an optimized design of combustion for agro-stalks and pharmaceutical waste.
Ethanol: Toxicity and Dangers in Women of Child-Bearing Age
Authors: Gard P.R.
Published: December 2021

The World Health Organisation estimates that alcohol abuse by adults accounts for about 5% of global disease burden. Additionally, prenatal alcohol exposure (PAE) causes ‘fetal alcohol spectrum disorder’ (FASD). Depending on severity, FASD is characterised by low birth weight, small head size at birth and growth retardation. There are also facial features of narrow eyes, flat upper lip and midface and impaired fine motor skills, hearing loss, poor hand-eye coordination and cognitive impairment. World-wide, up to 10% of children may be affected by PAE. It is unclear what dose or pattern of drinking results in these damaging effects, but animal models suggest that high, acute doses of ethanol (‘binge drinking’) in early pregnancy can result in the facial changes of FASD, whilst sustained, lower dose intake in later pregnancy produces anxiety and depression-like symptoms and deficits of learning and memory. The mechanisms underlying the deleterious effects of PAE are also unresolved, but evidence exists of long-lasting damage due to oxidative stress, increases in inflammatory mediators and changes to the brain renin-angiotensin system. There is also evidence of epigenetic changes. There is a need to prevent or limit the potential adverse effects of ethanol on the unborn child. It is highly unlikely, however, that all sexually-active women of child-bearing age not using reliable contraception will abstain from alcohol. There is therefore a need to research methods of reducing ethanol toxicity for the unborn child and / or develop therapeutic strategies to reverse the deleterious effects of ethanol on the unborn child.

Published: December 2021

Neste trabalho, discute-se em que medida livros didáticos de História (8º ano) se mostram abertos à diversidade cultural e às diferentes formas de existir, saber e estar no mundo. Para isso, são analisadas as características da história dos negros no Brasil veiculadas nas coleções “Nova História Crítica”, “Projeto Araribá – História” e “História Sociedade & Cidadania”. Como referência, são utilizados documentos oficiais (Lei 10.639/03 e diretrizes curriculares) e a literatura sobre multiculturalismo e educação. Os resultados indicam que os princípios veiculados, que integram e consolidam construções eurocêntricas, representam os negros predominantemente em condições de marginalização (pobre, escravizado, etc.). Tais resultados evidenciam que (1) os autores não têm sido capazes de produzir livros didáticos multiculturalmente orientados, que (2) estes livros se apresentam como território fértil de reprodução do daltonismo cultural e das relações sociais de desigualdade e dominação que tal daltonismo produz, e que (3) há uma relação íntima entre formação acadêmica dos autores e o conteúdo multicultural dos livros.

Diagnostics of a Tax Benefit in National and International Law (Methodological Aspects)
Authors:   Professor of the Department of Public Law of the National Research University Higher School of Economics (NRU HSE) LL.D., Khavanova Inna A.
Published: December 2021

The article is devoted to the aspects of substantiation of tax benefit in transnational operations. The schemes of tax evasion including transnational ones face strong opposition in national legislation, judicial doctrine and provisions of international agreements. In author`s opinion, now the doctrine of unfounded tax benefit is at the new stage of development after the adoption of the resolution of the Plenum of the Supreme Arbitration Court of the Russian Federation on appraisal by arbitration courts of relevance of gaining of tax benefit by tax residents, dated October 12 № 53. The author examines interaction between internal (Article 54.1 of the Tax Code of the Russian Federation) and international tax rules taking into account new approaches adopted after the OECD/G20 Base Erosion and Profit Shifting Project was realized. Special attention is paid to Multilateral convention to implement tax treaty related measures to prevent base erosion and profit shifting particularly to principle purpose test. The author notes that principle purpose test was designed on the basis of legal link between principal purposes of tax payer transaction and object and purpose of international agreement. The nature of such approach can be explained by peculiarities of international agreements for the avoidance of double taxation and the prevention of fiscal evasion with respect to taxes on income.

Tax Treaties and Enterprise Outcomes: Evidence Across Developing African Countries
Authors: Efobi Uchenna , Adejumo Oluwabunmi O.
Published: December 2021

Studies have noted the possibility of tax treaties constraining the tax policy autonomy of developing countries, while their impact on enterprise development within host economies remains an empirical issue. This study examines the effects and heterogeneous differences in estimated effects of tax treaties on small businesses in developing countries that agree to these agreements. The study uses the ICTD tax treaties dataset and the World Bank Enterprise Survey data to set up a quasi-experiment framework for selected African Countries. The framework compares countries’ outcomes for small businesses that ratify and enforce a tax treaty and those without a ratified tax treaty for the years pre-2005–2010 and post-2011–2019). We find that tax treaties signed and enforced by developing countries in Africa have a consistent, negative relationship with small business outcomes. These results are driven by the enterprise’s size and internationalisation status but not by the subsidiary status of the sampled small businesses. The findings have implications for policy targeted towards industrial development alongside tax treaty negotiations.

This brief illustrates how COVID-19 vaccine (in)equity has played out on the ground and offers key considerations for how it can be improved in the North West London (NWL) borough of Ealing. We conducted a review of literature and several informal consultations with local actors involved in COVID-19 vaccination efforts in statutory bodies (local authorities and the NHS) and the community in order to build a picture of and contextualise COVID-19 vaccine uptake in Ealing. Key considerations and lessons for achieving greater vaccine and health equity are presented, followed by additional context of interest to responders within statutory authorities and the community. This brief was produced by SSHAP in collaboration with partners in Ealing Council. It was authored by Tabitha Hrynick and Santiago Ripoll and is the responsibility of SSHAP.
Advances in traceability systems in agri-food supply chains
Authors:   University of Cambridge, UK, Islam Samantha , Manning Louise ,   Royal Agricultural University, UK, Cullen Jonathan M. ,   University of Cambridge, UK
Published: December 2021

Failure to deliver safe and high-quality food reduces consumer confidence in the food industry and results in costly food crises, foodborne illnesses and disruption to food supply chains. Recent advances in traceability systems, and associated identification and communication technologies hold the potential to ensure food quality and safety by managing effective traceability throughout the food supply chains. However, deficits in various factors e.g., resources, awareness, training, standards, data management and technology scaling impede exploitation of these cutting-edge traceability technologies. This chapter provides a review of the advances in agri-food traceability systems and technologies, barriers to their implementations, and possible improvement pathways and policy interventions to promote deployment of advanced food traceability systems.
Advances in techniques for identifying and tracking foreign bodies in agri-food supply chains
Authors:   University of Belgrade, Serbia, Djekic Ilija
Published: December 2021

Foreign bodies in food can occur at any stage in the agri-food supply chain continuum, and they are recognised as the main single source of customer complaints. From a food safety perspective, these physical contaminants can cause adverse health effects, so food companies strive to have effective control measures in place to prevent their occurrence. One of proposed solutions is instalment of various detection systems focused on discovering different types of foreign bodies in food.

TO THE QUESTION OF ANALYSIS OF EQUATIONS OF MOTION OF A RIGID BODY DURING THE MECHANICAL OSCILATIONS
Authors: Dobrov Igor , Semichev Andriy
Published: December 2021

Depending on the current position of the mass in different areas of the spring deformation during the oscillation process the values that determines the natural frequency of free continuous oscillations have opposite signs. It is defined by the change in the direction of acceleration of the mass in these areas, which makes it possible to determine a single inhomogeneous differential equation of the oscillation process in different areas of the movement of the mass. When the oscillation amplitude is much less than the static position of the mass, this inhomogeneous differential equation represents a homogeneous differential equation of free undamped oscillations.

Finite element method of simulating frequency response function (FRF) for boring tool in LS-Dyna solver is investigated in this work. Nowadays, computer numerical simulation allows to obtain FRF using different materials model with high precision compared to real experiments with sensors like impact hammer testing. This function is used in construction of stability lobe diagrams that allows operator of machining center to avoid chatter self-excited vibrations. Such vibration is led to decreasing of productivity and quality in cutting of metals and other materials. Amplitude and phase angle for the model is obtained from LS-Dyna result interpreter, that reads binary files, created during simulation by the program. Amplitude and phase angle of frequency response function are depending on dynamic stiffness of machining system.

The material selection method is critically evaluated to enable high pressure (HP) turbine blades to deal with in-service damaging phenomena such as creep, low cycle fatigue and high cycle fatigue, oxidation and corrosion. The material selection method is analyzed in order to improve the service life of the aero engine. To increase the turbine inlet temperature, HP turbine blades need improved creep and fatigue resistance. more quality. By the typical working condition of HP turbine blade, using CES Edu Pack (CES) material selection software was used to select suitable materials for HP turbine blade material. Nickel based alloys are selected for HP turbine blades, such as Nickel-Cr-Co-Mo superalloy.

Abstract. The long-term operation of pipelines, which, in many cases, exceeds their regulatory service life, causes the strain ageing of metal, as well as the appearance of local mechano-corrosive damages. In this regard, the use of composites to reinforce worn pipelines constitutes one of today’s most promising technologies.

In this study, a comparative analysis was performed between the composite-reinforced steel pipe calculations that were conducted using the finite element method (FEM), and those that were conducted in accordance with the DSTU ISO 24817:2019 standard. The FEM numerical calculations were carried out using the complete factorial experiment design (consisting of three factors at three levels, with twenty-seven calculations in total). Based on the results of these calculations, a regression model was developed to assess the circular deformation of the pipe’s outer surface depending on the thickness of the bandage, the thickness of the pipe, and the internal pressure. The FEM calculations were found to be in close agreement with analytical results.

A method for estimating crack formation in a solid is proposed. The necessity the crack formation dynamics investigation is substantiated. Based on the Rebinder effect, a method for controlling the cracking nature using surfactants is proposed. The destruction by impact and explosion of samples pre-treated with water and surfactant is considered. It is established that pre-treatment of glass plates with surfactant solution shows a more uniform cracks distribution on impact, which may be the basis for the assumption that the surfactants use in blasting will significantly improve the crushing quality and reduce the oversized fractions yield. When examining the samples, which were saturated with surfactant solution, it is seen that the cracks system only increased after the explosion, small cracks appeared, which connect large ones. In the case of water use, we also see an increase in cracking, but it is not as intense and uniform as in the case of surfactants previous use. This result also confirms the fact that the pre-saturation of the medium with a surfactant solution before the pulse loads contributes to a more uniform crushing in the future and provides a basis for experiments on three-dimensional models in this direction.
