Principles of exposure of polymer materials to heat, moisture and UV-radiation and study of their properties by full factorial experiment: A review
Authors: Laptev A. B. , Nesterov A. S. , Vardanyan A. M. , Vardanyan A. M.
Published: August 2021

The work is dedicated to the effects of climatic factors on polyethylene terephthalate (PET) in terms of changes in the structure and interaction of polymer molecules. The kinetic concept of the strength of PET has been developed, and the factors influencing the strength have been considered. Effects of moisture, thermal oxidative destruction, and UV-radiation on the structure of PET have been investigated. Polymers’ properties predicting, durability and their computer modeling have been analyzed. A model of changes in PET properties under the influence of temperature, moisture and UV-radiation was constructed using the methods of a full factorial experiment. It has been shown that in the initial period of exposure, adsorption and diffusion of moisture, hydrolysis and surface oxidation occur; prolonged and constant exposure to UV-radiation break the bonds formed by moisture, then the C–C and C–O bonds in the PET molecule brake and new intermolecular bonds are formed. In the amorphous state of PET, the breaking of bonds in the polymer chain and the formation of bonds between two adjacent polymer chains, the formation of more densely packed nodes, the destruction of the polymer and its aging, are equally probable. Temperature has a secondary effect, facilitating both hydrolysis and oxidation and polymer degradation.

Published: August 2021

Background: The aim of this study was to assess the effect on short-term
outcomes and long-term survival in patients following coronary artery
bypass grafting in whom second arterial conduit(right internal thoracic
artery-RITA or radial artery-RA) or saphenous vein was grafted and
between RITA and RA as second best arterial conduit. Methods: Between
January-2006 and June-2018, 7857-patients met the inclusion criteria and
were divided into two groups: single internal thoracic artery: SITA+Vein
group(n=7140) and 2nd-arterial conduit group(n=717), of these
537-patients received RITA and 180-patients received RA. Short‐term
outcomes included: 30-day mortality and Major Adverse Cardiac and
Cerebral Events(MACCE), reoperation for bleeding and deep sternal wound
infection(DSWI). The long‐term outcome was all‐cause mortality.
propensity score(PS) matching was used to match patients between the
groups. Results: Before as well as after PS-matching, no significant
differences were observed between 2nd-arterial conduit vs SITA+Vein
groups and between RITA vs RA groups in terms of 30-day mortality,
30-day MACCE, reoperation for bleeding and incidence of DSWI. The use of
2nd-arterial conduit was associated with a significant reduction in
long-term mortality before(HR:0.52;95%CI;0.43-0.64;p<0.001)
as well as after PS-matching(HR:0.77;95%CI;0.60-0.99;p=0.04). RA and
RITA as second arterial conduit had comparable long-term mortality
before(HR:1.22;95%CI;0.82-1.82;p=0.3) as well as after
PS-matching(HR:0.96;95%CI;0.58-1.58;p=0.87). Conclusions: The use of
2nd-arterial conduit vs vein is associated with improved long-term
survival. As for the 2nd-best arterial conduit, RA and RITA had
comparable long-term mortality.

Authors: Al-Thomali Yousef , Basha Sakeenabi , Mohamed Roshan Noor
Published: August 2021

Objectives

To provide collective quantitative evidence about the effect of surface treatments on the mechanical stability of orthodontic miniscrews (MSs).

Materials and Methods

The study was registered in PROSPERO (No. CRD42020209652). The research question was defined according to the PICO (population, intervention, control, and outcomes) format. Various research databases were searched for animal and human studies on effects of surface treatment on the mechanical stability of MSs. Both prospective and retrospective in vivo clinical studies published in English were included. The risk of bias was assessed using SYRCLE's risk of bias tool for animal studies. The meta-analysis was conducted using RevMan 5.4.

Results

A total of 109 articles were identified; 14 were included in the systematic review, and seven studies with sandblasting, acid etching (SLA) methods of surface treatment were included for meta-analysis. The number of study participants ranged from 6 to 24 (total n = 185), with a mean of 13.2. A total of 949 MSs were used with a mean of 67.8. The overall success rate for surface-treated MSs ranged from 47.9% to 100%. Forest plot of removal torque values showed significantly higher values for SLA surface-treated MSs compared with controls with a standard mean difference of 2.61 (95% confidence interval = 1.49–3.72, I2 = 85%). Forest plot of insertion torque showed a standard mean difference of –6.19 (95% confidence interval = –13.63–1.25, I2 = 98%, P = .10).

Conclusions

Surface treatment of MSs improved primary and secondary stability with good osseointegration at the bone-implant surface. However, significant heterogeneity across the studies included in the meta-analysis made it difficult to draw conclusions.

Bariatric operations induce weight loss, which is associated with an improvement in hepatic steatosis and a reduction in hepatic glucose production. It is not clear whether these outcomes are entirely due to weight loss, or whether the new anatomy imposed by the surgery contributes to the improvement in the metabolic function of the liver. We performed vertical sleeve gastrectomy (VSG) on obese mice provided with a high-fat high-sucrose diet and compared them to diet and weight-matched sham-operated mice (WMS). At 40 days after surgery, VSG-operated mice displayed less hepatic steatosis compared with WMS. By measuring the fasting glucose and insulin levels in the blood vessels feeding and draining the liver, we showed directly that hepatic glucose production was suppressed after VSG. Insulin levels were elevated in the portal vein, and hepatic insulin clearance was elevated in VSG-operated mice. The hepatic expression of genes associated with insulin clearance was upregulated. We repeated the experiment in lean mice and observed that portal insulin and glucagon are elevated, but only insulin clearance is increased in VSG-operated mice. In conclusion, direct measurement of glucose and insulin in the blood entering and leaving the liver shows that VSG affects glucose and insulin metabolism through mechanisms independent of weight loss and diet.
Weldability improvement by wobbling technique in high power density laser welding of two aluminum alloys: Al-5052 and Al-6061

Published: August 2021

This paper presents a new approach in laser welding of Al-5052 and heat Al-6061 aluminum alloys, which are challenging materials for a good laser welding quality. The process consists of applying very small size of 0.1 mm to provide a high density of power that aims at imposing a high amount of heat that is required for aluminum alloys; simultaneously the wobbling technique is implemented to reduce the risk of overheating in the welding area. Having relied on the capability of the wobbling technique to distribute the generated heat, welding results contained negligible thermal defects compared to the usual defects such as underfill, undercut, and root reinforcement. The resulted welding zones show a fully penetrated welding quality for both alloys with a smooth weld seam at the top and root surface. Analysis indicates a higher tensile strength of 190 MPa for Al-5052 corresponding to an 18% decrease from the base metal, while this reduction of mechanical strength in the welded zone for Al-6061 was about 27%. Also, the hardness profile of Al-5052 reveals a small reduction in the fusion zone in contrast to Al-6061, for which a high hardness decrease happens in the welded zone. This approach is more profitable for the cost-effectiveness of the process since the laser power is set at a low range as the high-power density is mainly related to the small size of the spot diameter.

Combinatorics is a branch of mathematics that is very important, but this topic has not received serious attention in educational research compared to other branches of mathematics such as geometry, calculus and algebra in Indonesia. Meanwhile, in secondary and undergraduate education, existing research reports that students’ combinatorial thinking ability tend to be low. Efforts to improve students’ combinatorial thinking ability in one of the Vocational Schools in Medan, Indonesia, are carried out through the development of the Numbered Heads Together (NHT). NHT is one cooperative learning structure. The result showed that NHT learning improved students’ combinatorial thinking ability.

Published: August 2021

The purpose of the research is to determine the effectiveness of the established integrative model of the musical art teacher’s professional training by means of innovation technologies based on a survey of students, in order to reveal the benefits of using the integrative model in educational institutions. The research methods: comparative analysis; systematization; generalizations, surveys. It has been established that the implementation of an integrative model of the musical art teacher’s professional training by means of innovation technologies demands from students to conduct the preliminary investigation of the topic and its basic understanding, as well as comprehension of how all the “parts” of the topic correlate. As a result of the research conducted, it has been revealed that the integrative model formation of musical art teacher’s professional training by means of innovation technologies is a complex process due to the abundance of variables that should be taken into account both in the curriculum and at the individual level.
International Evidence on Extending Sovereign Debt Maturities
Authors:   Federal Reserve Bank of San Francisco, Christensen Jens H. E. , Lopez Jose A , Mussche Paul
Published: August 2021

Portfolio diversification is as important to debt management as it is to asset management. In this paper, we focus on diversification of sovereign debt issuance by examining the extension of the maximum maturity of issued debt. In particular, we examine the potential costs to the U.S. Treasury of introducing 50-year bonds as a financing option. Based on evidence from foreign government bond markets with such long-term debt, our results suggest that a 50-year Treasury bond would likely trade at an average yield that is at most 20 basis points above that of a 30-year bond. Our results based on extrapolations from a dynamic yield curve model using just U.S. Treasury yields are similar.
Nativised English Lexemes and Semantic Shift in Malaysian English
Authors: Mohd Nasir Nur Fatima Wahida
Published: August 2021

In Malaysia, Malaysian English is a variety that is very much known by the speech community and commonly used for colloquial communication. Although many studies have been conducted in exploring the development of ME within various aspects, little research have focused on the development of English lexemes of semantic shift in ME. Thus, as empirical literatures in the field have shown that lexis and semantics are constantly evolving from time to time, it is imperative that more research studies should also be conducted to investigate on the identification of frequently used indigenized English lexemes as well as validating its meanings in the Malaysian context so that linguists and researchers will have a better understanding on the current lexical trends in Malaysia and so that more research can further explore other aspects of these current trending lexicals among different social groups in the Malaysian speech community. Based on a descriptive cross-sectional survey approach through the distribution of questionnaires, findings shows that frequently used English lexemes of semantic shift in ME are found to be under the category of informalization in ME and that most of the meanings of the words in the study were agreed by respondents. However, comments from the respondents also shows that several words could also have wider and deeper meanings in ME which is why this study suggests that further research studies can be conducted to investigate this phenomenon.
Monitoring of public adviser’s activities: experience of paraprofessional social workers
Authors: Yeroshenko Kateryna
Published: August 2021

This article outlines approaches to the monitoring of paraprofessional activities in the field of social work on the example of international and Ukrainian experience. The article aims to highlight alternative options for monitoring the work of paraprofessional social workers: on the basis of social services, within the inclusion in an intradisciplinary team, as well as in the format of individual activities of paraprofessionals in society. Based on the results of a desk study of international experience in monitoring the activities of paraprofessional communities, analysis of monitoring reports and surveys of public advisers in Ukraine who are paraprofessionals and work individually in small communities, practical issues of monitoring procedures for paraprofessionals are considered. The complexity of monitoring the activities of this network is connected with the fact that the functions of community advisers are new to the practice of Ukrainian social work, since everyone in this network works in his / her own format. In the context of this monitoring complexity, the analysis was made on the limitations of existing monitoring procedures of the network of public advisers. The results of this study revealed the limitations of formalized and functional approaches to the analysis of paraprofessionals in social work, such as: ineffective approach to paraprofessionals whose functions are blurred, lack of motivation and perception of monitoring procedures as control by professionals. In addition, taking into consideration the demand from the community of public advisers, some alternative approaches to monitoring the activities of paraprofessional volunteers have been proposed, including the motivation-centred approach based on the supervision of public advisers in the performance of their functions.
Family social work: the realities of Ukraine
Authors: Stoliaryk Olha , Zubchyk Olha , Semigina Tetyana
Published: August 2021

The family social work in Ukraine is only at the stage of its developing. Deriving from the paternalistic philosophy, the demonopolisation of the market of social services places new demands on social policy aimed at implementing and regulating social work with families as a separate social structure. The purpose of the research is to characterise the institutional structure of family social work, to determine the assessment of social services and their quality on the example of a study of families raising children suffering from autism, basing on the system- and structure-centred analysis. The paper highlights the indicators of family-oriented practice, describes the market of social service providers for families, identifies the functions of individual institutions, structural entities and the specifics of their activities. It is revealed that in Ukraine there are two types of social work with families: regulated (state bodies and structural entities) and unregulated activities (individuals-entrepreneurs, public organisations, charitable foundations, volunteers), but this does not ensure its integrity, because most social service providers are not focused on the needs of families of certain social categories. The family social work in Ukraine could be divided into three types in the framework of its professionalization: a professional activity, a non-professional activity and a "mixed" (partly professional) activity. The survey provides an assessment of individual indicators of social services by the families raising children who suffer from autism (targeting family social work, access to services offered in the region, the presence of stigma, the effectiveness of social advertising of existing services, their compliance with family needs, etc.). It was discovered that most of the services offered are not in demand; they do not take into account the contextual and environmental background in which families operate either; service providers are biased towards families raising children with autism. Many families are in an information vacuum, which becomes an obstacle to expanding their rights and opportunities, the work done with them can be defined as fragmentary and chaotic; it does not take into account the role of the community in maintaining family resilience.

In the theoretical block of the article, the directions of application by countries of specific features of one country in the educational space of another are viewed through the prism of an agreed educational policy, complementarity of national educational systems, synchronization of actions achieved on the basis of regulation by supranational institutions. The article adapted foreign experience, including new trends in the field of education: decentralization and democratization of management, modification of educational programs and standards, the creation of non-state educational institutions, updating of the regulatory framework and the financial and economic mechanism in the field of education. Cooperation between the EAEU member states in the field of education was considered as a mechanism for the most effective development and solution of global problems. International academic mobility is analysed as one of the most important co-sponsoring processes for the internationalization of higher education and the integration of universities into the world educational space. The practical block is devoted to the problems of the formation and evolution of the educational services market in the conditions of innovative development of Russia and Belarus as members of the Eurasian Economic Union. The peculiarities of integration of education systems of Russia and Belarus in the market of educational services of the EAEU are considered. Factors leading to integration of member countries at the level of individual educational institutions are being investigated. Trends of gradual development of national educational systems of their state framework and emergence of foundations of unified educational space of the Eurasian Economic Union are analyzed. Trends are highlighted that hinder the development of the export of educational services of the Eurasian Economic Union.

Para responder a la variedad de sujetos dentro del espectro autista y a la diversidad de lugares que los reciben y que prestan atención al baño de lenguaje en el que esos sujetos están sumergidos, la orientación de nuestro trabajo apunta a definir la posición de un terapeuta partenaire respetuoso de los múltiples aspectos que puede tomar el efecto transformador de un encuentro nuevo con la lengua. Desde esta perspectiva, más que de la búsqueda de un método ideal para el abordaje del sujeto con autismo, se trata de presentar aquí la diversidad de resultados obtenidos en contextos de lo más variados cuyo rasgo constante es sostener el esfuerzo de inscripción del sujeto en todas las dimensiones de la lengua, de la instancia de la letra y del tratamiento de los objetos fuera del cuerpo tales como la mirada y la voz, en la gran variedad de situaciones o de talleres posibles, manteniendo al mismo tiempo los aprendizajes (fragmento del manuscrito).
Autismo y psicoanálisis. Una apuesta del lado de la vida
Authors: Lijtinstens Claudia
Published: August 2021

Cuando la inscripción de la dimensión simbólica del lenguaje no se produce eficazmente el niño debe encontrar soluciones singulares para estructurar la realidad, su cuerpo y los objetos pulsionales que se despliegan entre la necesidad, la demanda y el deseo. El “tratamiento” que algunos niños realizan en relación a su cuerpo, a los objetos pulsionales y al Otro en ese intento de organización de su mundo -muchas veces extraño, paradojal, repetitivo e incomprensible-, dan cuerpo a la noción de autismo. La operación propia del psicoanálisis sobre la escritura del síntoma consiste en leer el modo en que cada sujeto elabora un pequeño circuito o cadena que instaura un montaje defensivo a la luz de una articulación entre cuerpo, objetos y lenguaje que se vuelve soporte de una acción no sometida a la interlocución simbólica ni dominada por la reciprocidad imaginaria, inventando junto al sujeto un modo de funcionar del lado de la vida y del deseo.

Use of imaging-guided intensity-modulated stereotactic body radiation therapy to treat a well-differentiated hepatocellular carcinoma in a dog
Authors: Yang Ester , Kubicek Lyndsey , Pavletic Michael M.
Published: August 2021

CASE DESCRIPTION

A 14-year-old 5.6-kg (12.3-lb) castrated male Toy Poodle was evaluated because of high serum activities of alkaline phosphatase and alanine amino-transferase and the presence of a hepatic mass.

CLINICAL FINDINGS

Abdominal CT revealed a large (approx 6.8 X 7.1 X 6.5-cm) soft tissue mass along the midline of the liver. The mass either originated from the papillary process of the caudate lobe or the left medial liver lobe.

TREATMENT AND OUTCOME

A partial liver lobectomy was performed, and approximately a third of the mass was successfully removed and submitted for histologic examination. Consultation with the oncology service was advised to determine whether radiation therapy could be used to treat the residual disease. On 5 consecutive days, the dog underwent imaging-guided intensity-modulated radiotherapy-stereotactic body radiation therapy (4 Gy/treatment) with a simultaneous integrated boost to the center of the tumor. The dog received a base dose of 20 Gy that was then boosted to 28 Gy. In the 10-month period after completion of radiation therapy, the hepatocellular mass continued to decrease in size, and overall improvements in the dog's serum liver enzyme abnormalities were evident.

CLINICAL RELEVANCE

There are few treatment options for dogs with incompletely excised hepatocellular carcinomas. On the basis of the positive outcome in this case, radiation therapy could be useful following incomplete surgical removal of hepatocellular carcinomas in dogs. (J Am Vet Med Assoc 2021;259:392–395)

Published: August 2021

Authors have studied the antitumor efficacy of contact radiation therapy (CRT) in combination with a chlorin-based photosensitizer (PS) in an experiment on laboratory animals with transplanted tumors. The experimental study was performed in 50 white outbred rats weighing 250±50 g. Subcutaneously transplanted Pliss lymphosarcoma (PLS) and alveolar liver cancer RS1 (RS1) were used as tumor models. Chlorinbased PS photolon (RUE «Belmedpreparaty», Republic Belarus) was injected intravenously at a dose of 2.5 mg/kg. The radiation sessions were carried out 2.5–4 hours (depending on the tumor model) after the administration of the PS using the device «microSelectron HDR V3 Digital» («Nucletron», Netherlands) with a 192-Ir radiation source in single focal doses 5 and 10 Gy. All laboratory animals (for PLS and RS1) were subdivided into 5 groups of 5 animals each: intact control, CRT 5 Gy, CRT 10 Gy, PS + CRT 5 Gy, PS + CRT 10 Gy. For the PLS tumor model – on the 14th day from the beginning of the experiment Vav. in groups were 26.31±5.81; 22.45±6.97; 18.99±4.86; 10.75±5.18 and 28.06±2.85 cm3, respectively (p˂0.05). The coefficients of tumor growth inhibition in the experimental groups were 14.67%, 27.82%, 59.14% and 6.65%, respectively. The frequency of complete tumor regressions 60 days after the start of the experiment was 0%, 20%, 20%, 60%, and 20%, respectively. On RS1 tumor model – on the 14th day from the beginning of the experiment Vav. in groups were 4.48±1.03; 0.80±0.21; 0.29±0.09; 0.19±0.07 and 0.32±0.08 cm3, respectively (p=0.009). The coefficients of tumor growth inhibition in the experimental groups were 82.14%, 93.53%, 95.76% and 92.86%, respectively. The frequency of complete tumor regressions 60 days after the start of the experiment was 0%, 0%, 20%, 0%, and 0%, respectively. Systemic administration of chlorin-based PS before the CRT session increases the antitumor efficacy of radiation therapy in animals with transplantable tumors of different histological structure and growth patterns. The data obtained indicate that further studies of the radiosensitizing properties of PS are promising.

The objective of the present work was to evaluate the effect of carboplatin (Cp) on submandibular gland homogenate of Wistar rats through the determination of malondialdehyde levels, as the main end product of lipoperoxidation, in an experimental model.Sixteen three-month-old male Wistar rats were used, housed in individual cages, with controlled temperature and lighting and free diet. A completely randomized design was used and two experimental groups were established: 1) Control (C), administering an intraperitoneal dose of saline solution for one day, n: 8, 2) Animals treated with carboplatin (Cp) applying a dose i.p. of 100 mg / Kg of body weight for one day, n: 8. The animals were fasted for 24 hours and subsequently anesthetized. Then both submandibular glands were removed. Malondialdehyde levels were analyzed in submandibular gland homogenatein both experimental groups. Variations between the groups analyzed were evaluated using the Student's t test for paired samples, setting a p-value <0.05 for statistical significance. Project approved by CICUAL. Faculty of Medical Sciences (UNC).The group of Rats Co showed a concentration of 7.32± 0.48μmol / mg of gland. The Cp group had a concentration of 12.57 ± 0.71 μmol / mg of gland, expressing a significant decrease compared to the control group p <0.0006. Cp at the dose tested would cause a decrease in lipoperoxidation in the submandibular gland of rats. Possibly the glandular antioxidant battery would neutralize the oxidative stress of acinar cells. These results suggest a future evaluation of superoxide dismutase (SOD) activity and uric acid (UA) levels

Published: August 2021

Este artigo aborda a emergência recente dos temas da gestão florestal e da regularidade ambiental como problemas públicos e a inclusão destes na agenda de políticas públicas brasileiras por meio das leis federais no. 11.284/2006 e 12.651/2012. Trata-se de um estudo de caso exploratório que articula pesquisa bibliográfica e documental, bem como pesquisa-ação em processos de regularização fundiária e ambiental no intuito de: i) compreender o contexto de “caos fundiário” existente na Amazônia Legal, que ajudou a levar os temas da regularidade fundiária e ambiental ao topo da agenda de políticas públicas; ii) identificar algumas ideias institucionalizadas pelas políticas públicas supramencionadas; iii) mapear conflitos existentes entre entendimentos, diretrizes e objetivos desses marcos legislativos; e iv) apresentar dados preliminares relativos a execução do Cadastro Ambiental Rural no território paraense em geral, e no marajoara em particular. Como resultados deste artigo, conclui-se pela persistência da lógica da apropriação ilegal das terras e dos recursos florestais do Marajó por alguns segmentos econômicos, a qual é facilitada pela dificuldade de acompanhamento dos processos de cadastro pelos órgãos governamentais e pela sociedade civil.
