Fabrication and characterization of Cs2SnI6 perovskite films using SnI2 and I2 powders as reactants
Authors: Ullah Saad , Yang Peixin , Abbas Ghulam , Chen Yongsheng
Published: October 2021

In the recent years, cesium tin iodide (Cs2SnI6) double perovskite has emerged as a research hotspot in photovoltaics due to its exceptional stability and outstanding optoelectronic properties. In this work, we have utilized a reactant combination of SnI2 and I2 to prepare uniform Cs2SnI6 films via modified two-step process. The impact of the reaction conditions on the structural, morphological and optical properties is explored. It is found that optimizing the reaction conditions improves the phase stability and morphology of the films. The iodine-rich fabrication of the films ensued in enhanced PL and optical characteristics of the Cs2SnI6 with an optimal bandgap in the range of 1.21-1.34 eV. Additionally, we constructed all-inorganic photovoltaic devices FTO/TiO2/Cs2SnI6/Carbon utilizing optimized Cs2SnI6 films.

Published: October 2021

Along with the many known benefits of cover crops, they may be an effective ecological weed management strategy in low-input agriculture. This research aimed to determine the effect of cover crops, combined with reduced-tillage and nitrogen inputs on sweet corn (Zea mays) yield and weed communities. During the 2-year study, the impact of the cover crop on yield varied. Yield within the no-till conventional treatment plots was not significantly different from the conventional treatment [6844 and 7721 lb/acre (P = 0.592)] in year 1 but differed in year 2 (P = 0.003). Weed density and experimental area covered by weeds were not significantly different between conventional and no-till conventional treatments. Multivariate analyses showed associations between specific weed species and management practices. Weeds were greatest in no-till organic treatments, and they had significantly lower yields, suggesting additional weed control beyond cover crops may be necessary for organic vegetable systems under reduced tillage.
Solving structural design challenges with generative solutions
Authors: Pomazan Valentina M.
Published: October 2021

Topology optimization is one of the main engineering problems, that should be addressed from the conceptual stage. An existing design is developed through traditional means and attempts to optimize it through an algorithmic postprocess, regarding various criteria. Physical systems that determine fixtures or contact in the assembly relate to design constraints, while the outcome material, optimal distributed, responds to criteria like minimal mass or maximum stiffness. The paper presents the principles and criteria used in shape design. Using a case study in Fusion 360 Generative Design workspace, the preserves and obstacles in generative design are identified at components and equipment level, along with main parametric CAD geometric definitions. The results in the generative solutions proposed for a given fixture are graphically presented and explained, also, analyzed from the manufacturing point of view.

Authors: Angadi Sangamesh V. , Entz Martin H.
Published: October 2021

Dwarf sunflower (Helianthus annuus L.) cultivars have agronomic and management benefits over conventional standard height sunflower cultivars. However, the effects of reduced plant stature on root systems and water extraction characteristics are not known. Therefore, field trials were conducted at two locations in western Canada during 1994 and 1995 to compare root system characteristics and water extraction patterns of dwarf hybrids [two Sunwheat hybrids: ‘Sunwheat‐101’ (SW‐101) and ‘Sunwheat‐103’ (SW‐103)], and dwarf open pollinated cultivars [two Sunola cultivars, ‘AC‐Aurora’ (Aurora) and ‘AC‐Sierra’ (Sierra)] with standard height hybrids (IS‐6111 and SF‐187). Reducing plant height reduced rooting depth (by 0.20 to 0.60 m), root length density (by 6.6 m m−2) and root distribution in SW‐103 compared with IS‐6111, while no differences were observed in these traits between IS‐6111 and Aurora. The soil water depletion front velocities of sunflower cultivars were influenced by accumulated heat units, suggesting a temperature effect on rooting characteristics. IS‐6111 (0.14 to 0.19 cm growing degree d−1) and Aurora (0.15 to 0.17 cm growing degree d−1) had significantly higher depletion front velocities compared with SW‐103 (0.09 to 0.11 cm growing degree d−1). Greater soil water depletion by standard height hybrids in agronomy trials (average 59 and 79 mm more compared with dwarf hybrids and dwarf open pollinated cultivars, respectively) was attributed to deeper rooting depth (average 0.2 and 0.4 m more compared with dwarf hybrids and dwarf open pollinated cultivars, respectively) and more efficient water extraction, although a longer growth duration may also have been a factor.

Published: October 2021

Suitability of alternative crops in the northern Great Plains remains a question because of water limitations. Objectives were to compare water use of an oat (Avena sativa L.)–pea (Pisum sativum L.) mix grown for hay (OPH) to that of black lentil (Lens culinaris Medikus cv. Indianhead) grown as green manure (BL). Water use and plant biomass for OPH and BL were measured near Culbertson, MT (Site 1), during 4 yr. Soil water was measured by neutron attenuation. Precision‐weighing lysimeters were used at Site 2, located 65 km southeast of Site 1, to measure water use. Soil was a Williams loam (fine‐loamy, mixed, superactive, frigid Typic Argiustolls). Biomass of crops was measured biweekly. Relative feed value (RFV) based on measured neutral detergent fiber and acid detergent fiber was calculated. Biomass under OPH was 34 and 46% greater than with BL at Sites 1 and 2, respectively. At Site 1, biomass accumulated at a rate of 14 kg ha−1 mm−1 water used under BL and 23 kg ha−1 mm−1 under OPH. Biomass accumulated at a rate of 21 kg ha−1 mm−1 under BL and 29 kg ha−1 mm−1 under OPH at Site 2. Hay RFV, at full bloom in pea, averaged 116 (Number 2 hay), and this did not change appreciably as the crop matured to soft dough stage in oat. Oat–pea hay fits the growing conditions in the northern Great Plains and meets the needs of producers for high quality hay.

Nitrogen fertilizer is routinely applied to crops grown in rotation with upland cotton (Gossypium hirsutum L.) in the San Joaquin Valley (SJV) of California. However, increasing N fertilizer costs, the potential overuse of N resulting in excessive vegetative growth and harvest delays, increasing pest pressure, and concern for nitrate contamination of groundwater support a reassessment of current N fertilization practices. The primary goal of this research was to provide information that would assist SJV cotton growers in updating and improving N management practices. Plot site selection included two university field stations and six on‐farm locations representing all SJV cotton‐producing counties. Nitrogen treatments of 56 to 224 kg N ha−1were over a 5‐yr period. Cotton lint yield responded positively to increasing N applications in only 41% (16 out of 39) of the test sites. Yield response to fertilizer N was related to residual soil N in the upper 0.6 m of soil as follows: below 70 kg ha−1residual NO3–N, 9 of 17 sites responded positively to increasing applied N; at 70 to 125 kg ha−1, 5 of 11 sites responded; and at greater than 125 kg ha−1, only 2 of 11 sites responded. Changes in soil NO3–N levels from postplanting to postharvest were generally larger within the upper 1.2 m of soil than at lower depths. However, net increases in soil NO3–N also occurred in the 1.2‐ to 2.4‐m range at sites prone to leaching.

Published: October 2021

Kernel smut, Neovossia horrida (Tilletia barclayana), of rice (Oryza sativa L.) has been a persistent disease in Arkansas for more than 50 yr. Recently, epidemic levels of kernel smut have occurred on highly susceptible cultivars, which have increased awareness within the rice industry of this disease. Nitrogen fertilization treatments consisting of four preflood (50–152 kg N ha−1) and three midseason (0–100 kg N ha−1) N rates were arranged in a factorial design and used to delineate the effects of N rate and application timing on rice yield and disease incidence and severity in five site‐year–cultivar studies (environments). Significant environment × preflood N rate interactions occurred for yield, incidence, and severity. The minimum preflood N rates, averaged across midseason N rates, that produced maximum yields varied among the environments and ranged from 84 to 152 kg N ha−1. Depending on the environment, disease incidence ranged from 2 to 93% and severity ranged from <0.1 to 4.8% among preflood N rates. Preflood N rate had no significant effect on smut incidence and severity for three environments receiving optimum‐to‐excessive N and a fourth environment receiving inadequate‐to‐optimum N. For the remaining environment that received optimum‐to‐excessive N, incidence increased linearly (43–93%), and severity increased nonlinearly (0.5–4.8%) as preflood N rate increased. Midseason N rate did not affect severity but caused a positive, linear increase for incidence. Data suggest that excessive preflood N has the greater potential to increase kernel smut but only when environmental conditions are favorable for kernel smut.

Published: October 2021

This paper aims to examine the impact of emotional intelligence (EQ), employee empowerment (EE), and cultural intelligence (CQ) on commercial bank employees’ job satisfaction in Bangladesh. For this purpose, a survey questionnaire was developed based on pre-tested constructs. The study used a convenience sampling technique, supplemented by a non-probability sampling method. 200 bank employees were invited to participate in the survey; finally, 130 responses were received as fully complete, with a 65% response rate. Hence, the sample size is n = 130. Cronbach’s alpha value was used to determine the internal consistency of the study constructs. SPSS version 26.0 was used to analyze the correlation test and hypotheses test. The findings show that emotional intelligence (EQ) with a beta (β) value of 0.510 has a statistical and positive effect on bank employees’ job satisfaction. Also, employee empowerment (EE) with a beta value of (β) 0.418 and cultural intelligence (CQ) with a beta (β) of 0.372 were found to be significant predictors of job satisfaction. This indicates that bank managers should utilize EQ and CQ to increase bank employee satisfaction and focus on employee engagement at the workplace. According to the study, if bank employees become more emotionally stable and culturally intelligent at their workplace, they will be more satisfied with their current jobs. Besides, if bank employees are given more opportunities to carry out their job responsibilities, they will be more satisfied with their jobs. The paper outlines several significant implications for commercial bank managers and offers some notable directions for future research.

Published: October 2021

The labeling of products containing GMOs above 0.9% results from the provisions of the law in force in the European Union. The aim of the study was to evaluate the presence of genetically modified rape in feed used in feeding farm animals in Poland. The research was based on the real-time PCR technique, using primers and event-specific probes. A total of 900 samples were analyzed. The research identified canola line GT73, resistant to glyphosate. Only in 12 samples did the content of this oilseed rape exceed the threshold above which the product must be labeled as containing GMOs. Conducting such controls is extremely important because of the possibility of contamination of feed free from genetically modified organisms, which are increasingly used in animal nutrition.

Em diversos estudos médicos relacionados com tempo de vida encontra-se situações onde uma parcela dos indivíduos em tratamento não irão experimentar o evento de interesse, isto é, serão curados ou imunes. Para modelagem desses dados, as técnicas estatísticas tradicionais não são adequadas, se fazem necessários modelos mais complexos e abordagem diferentes. Neste trabalho, propomos abordar esse tipo de dados considerando modelos de fração de cura com mistura e não mistura baseados em uma distribuição Chen, sobre uma abordagem Bayesiana para as estimativas dos parâmetros. Esse modelo proposto é aplicado em dados de câncer de mama e comparado com os modelos baseados na Weibull tradicional. Um estudo considerando o impacto na proporção de curados da presença do receptor de estrogênio é realizado. Os modelos propostos mostraram-se adequados para modelar dos dados, mensurando satisfatoriamente as frações de cura com e sem a covariável. Por fim, apresentamos partes dos códigos utilizados neste trabalho em um apêndice.
SIMULAÇÕES DE PROBLEMAS DE TRANSPORTE DE PARTÍCULAS EM GEOMETRIA X-Y
Authors: Lorensi Gustavo Alcides , Sauter Esequia , Souto de Azevedo Fabio
Published: October 2021

A equação de transporte é uma versão linear da equação formulada em 1872 por Ludwig Boltzmann que trata de fenômenos em dinâmica de gases rarefeitos. Devido ao seu elevado número de variáveis no espaço de fase e de sua estrutura integro-diferencial, simulações numéricas envolvendo tal equação exigem algoritmos complexos e de elevado custo computacional. Dentre as diferentes abordagens para contornar tal dificuldade está o Método de Nyström, o qual foi utilizado neste trabalho. O problema aqui tratado é a equação de transporte com espalhamento isotrópico em geometria X-Y com fronteira semi-refletiva. Embora a literatura dispõe de resultados numéricos para o fluxo escalar que resolve esse problema, ainda não havia sido descrita a formulação integral para a corrente de partículas utilizando esta metodologia. Neste trabalho é apresentada a formulação integral para o fluxo escalar e corrente de partículas bem como as discretizações dos operadores com as devidas remoções de singularidades, dado ênfase nas melhorias efetuadas nos algoritmos já utilizados nesse problema em trabalhos recentes, o qual foi otimizado e paralelizado com OpenMP e, a partir destes, resultados significativos na redução do tempo computacional foram obtidos para diversas condições.

ADAPTIVE GRADIENT METHOD FOR THE OPTIMAL CONTROL OF AN ANTICANCER THERAPY MODEL
Authors: Naozuka Gustavo T. , Rocha Heber L. , Almeida Regina C.
Published: October 2021

Cancer is a set of diseases whose mechanisms of emergence and growth are not completely known. Mathematical and computational models aim to contribute to a better understanding of these mechanisms in tumor dynamics. They can also be used to analyze the impact of anticancer therapeutic protocols. In this sense, we investigate a mathematical model of tumor growth dynamics from the optimal control point of view. We apply the Switching-Time-Variation method to solve the control problem and modify its implementation in order to reduce computational time. Our results show that the execution time of the adaptive method is significantly shorter, and optimal controls for the observed scenario are of the bang-bang type with administration by maximum tolerated dose. The analysis also suggests that the application of another drug capable of acting on resistant tumor cells is required.

O presente trabalho tem como objetivo avaliar o impacto da assimilação de dados pelo método variacional, na simulação do Weather Research and Forecast (WRF), em um caso de ciclogênese explosiva, ocorrida no sul do Brasil em 30 de junho de 2020. Avalia-se também a capacidade do Filtro Digital (FD), com a janela de Dolph-Chebyshev (FDDC), em filtrar ondas de gravidade espúrias nas soluções do modelo. A condição inicial para integração do WRF é gerada pelo Global Forecast System (GFS) das 12 UTC, fornecida pelo National Center for Enviroment Prediction (NCEP). Os dados de assimilação foram obtidos através das redes de compartilhamento mundial de dados do Research Data Archive (RDA), além dos dados das estações da região sul do Brasil acessadas pelo Banco de Dados Meteorológicos do Instituto Nacional de Meteorologia (INMET). Foram definidos 4 experimentos, EXP1 - previsões do WRF, EXP2 - WRF com o Filtro Digital (WRFDF), EXP3 - WRF com assimilação variacional tridimensional (WRFDA), EXP4 - WRF com assimilação variacional tridimensional e Filtro Digital (WRFDADF). O Filtro Digital mostrou-se uma importante metodologia para eliminação do ruído, gerado pelo desequilíbrio entre os campos de massa e vento, no começo da integração do modelo. Destaca-se a diminuição do erro nos experimentos com assimilação de dados, em especial no vento em superfície.

Neste trabalho, apresentamos um modelo discreto para analisar a dinâmica de um sistema hospedeiro-parasitoide-predador. Assumimos que a escala de reprodução do predador é muito mais lenta que as escalas de reprodução da espécie do hospedeiro e do parasitoide. Com a densidade do predador constante, a dinâmica pode ser descrita por um sistema de duas equações a diferenças. O crescimento da população de hospedeiros está de acordo com a função de Beverton-Holt e a resposta funcional Holling tipo III descreve o parasitismo e a predação. Através de simulações numéricas, observamos a existência de múltiplos estados de equilíbrio estáveis, além de soluções periódicas.

The Impact of Subjective Factors on Self-Assessment of Health by the Region Population
Authors: Shevchuk I. A. , Melnikova T. B.
Published: October 2021

The article estimates the impact of subjective perception of labour, medical and psychological factors on self-assessment of health by the population of Russian regions. The topicality of the subject is stipulated by rather low figures of expected healthy life span by regions plotted on the share of the population that assess their health as poor and very poor. Possibility to improve this indicator is being worked at within the frames of national projects. However, factors of high enough differentiation of values of health self-assessment by people of different regions have not been studied yet. With the help of multi-factor linear regression two stages of research were completed: for all regions and separately for groups of RF entities with dependent variables higher and lower than medial values. As a result it was found out that factors of subjective estimation of working conditions were the most significant for health assessment ‘very good'. Psychological well-being of women correlates with all assessments, while that of men is not statistically valuable. For groups of assessment ‘good' of lower than medial value and ‘satisfactory' of higher than medial value the factor impact was not identified. Regions of lower than medial value by the assessment ‘satisfactory' are subject to subjective assessment of the medical service quality, availability of chronic illnesses and working conditions. For RF entities with higher than medial value assessments ‘poor' and ‘very poor' only psychological well-being of women was statistically valuable. A detailed analysis by fixed norms was done for the city of Sevastopol. Results of modeling can act as auxiliary sources for developing the most effective for the given region strategy aimed at improving health of people and its self-assessment.
Current Experience of Graduates’ Career Planning and Its Use for Identifying Requirements and Setting Goals for Career Centers at Universities

Published: October 2021

Every university graduate faces a problem of employment. A young specialist without work experience can hardly find a job by his/her specialization, which would allow them not only to use the acquired knowledge but also to get an adequate estimation of their efforts. Today Russian universities adopt the overseas experience in career promotion by helping graduates in their career planning, as today's higher education institutions in Russia are extremely interested in graduate's career development and at the same time in successful functioning of the university in general. The article grounds the necessity to set up Employment and Career Centers at universities, whose organizational and economic characteristics and trends of development can give an opportunity to accumulate and allocate the best practices of graduates' career planning and technical and technological support of interaction with business partners for different categories of graduates. Here a young specialist can find consultations of career experts, help in compiling a competitive CV and assistance in searching for a suitable vacancy. At the same time the Employment and Career Center at the university can carry out an important function of informing university employees about the necessity and importance of graduates' career planning and stimulating graduates' interest in self-organization and professional self-development.
Optimizing the Finance Structure of Capital at Commercial Organization
Authors: Ermakova Yu. S.
Published: October 2021

In conditions of limited finance resources building optimum finance structure of capital is considered the most important objective, as the availability of the necessary amount of own funds can provide finance sustainability of the organization, the potential to meet timely liabilities to creditors, finance and develop new lines of work. However, any resources (both borrowed and own) have value, as they can be invested into the profitable investment project. It is obvious that the finance structure of capital can influence indirectly the level of organization profit, as in other expenses interest costs or interests payable are shown. Therefore, it is necessary to build such a correlation of own and borrowed sources, which can provide the max profit for the enterprise. As tools for building such a correlation the article proposes methods of mathematic modeling and, namely, the correlation analysis to find the interconnection between the dependent variable, i.e. work profitability and different factors - a share of own and borrowed funds. On the basis of this interconnection regression equation was built, which allows us to find out how the amount of net profit changes with a certain correlation of own and borrowed resources. The analysis was carried out based on published finance reports of the limited company ‘Gazprom Bureniye'.

Published: October 2021

The article provides the analysis of current finance mechanisms of developing power systems in the context of acute necessity to start a new investment cycle. It draws a conclusion that state policy in the field of power engineering cannot foster the development of such mechanisms of its financing as state subsidies on purchase and installation of equipment, contracts on buying electricity and power-service contracts. The analysis of extra opportunities of raising investment showed expediency of developing green mechanisms of financing power engineering in Russia and motivating power companies to conduct IPO. The authors put forward recommendations aimed at attaining the acute objective to develop and implement key initiatives promoting the start of a new investment cycle in order to raise funds for modernizing the existing power projects and opening new ones in accordance with higher ecological requirements. For example, to stimulate the growth of Russian companies' IPO and realize the investment potential of the Russian stock market the Central Bank of the Russian Federation and the Ministry of Economic Development study the possibility to introduce new tax preferences for investors and companies entering the market, which could ensure institutional support for investors and issuers.

An Autosegmental Analysis of Tone Usage Among Yoruba-Speaking CVA-Aphasic Adults
Authors:   University of Ibadan, Agbeye Mercy Oluwaseyi , Kapau Humphrey Muyambango ,   University of the Western Cape
Published: October 2021

This inquiry investigated tone use among Yoruba-speaking adults recovering from an aphasic insult/attack initiated by a cerebral vascular accident (CVA), otherwise known as a stroke. In pursuing the aim of the study, the research was guided by three research questions, namely, do Yoruba-speaking aphasic adults have the perceptual ability to perceive tone in the language; can Yoruba-speaking aphasic adults differentiate between the three lexical tones in the language; and which of lexical tones do Yoruba speaking aphasic adults find difficult to perceive? The study drew upon the theoretical and analytical scope of the autosegmental approach and a constructivist methodology paradigm inspired by a descriptive research design that used the qualitative approach. Data elicited from purposively sampled informants via structured interviews involving two groups of participants three aphasic Yoruba individuals and three Yoruba non-aphasic individuals in Nigeria. The purposive sampling was premised on informants’ dialectal proficiency, availability and diversity, and occurrence of CVA (stroke). The aphasic subjects were identified with the initials AB, CD and EF to conform to confidentiality etiquette in clinical linguistics. For ethical consideration, the informants were required to fill in a consent form before eliciting data from them. Once that was done, the aphasics were availed 100 words from the combined Swadesh 200 and Ibadan 400 wordlist of essential and cultural items, recorded by the non-aphasic individuals who speak Yoruba as their first language, to identify which tones they perceive. The data elicited was analysed using the perceptual approach in which the recorded data was listened to several times to discover if adult Yoruba speakers that are aphasic were still able to recognise the high ( ́), mid ( ̄) and low tone (̀ ) in words. The findings reviewed that Yoruba aphasics have diverse perceptual abilities of tone. Furthermore, it was established that Yoruba aphasics displayed varying deficiencies in differentiating the three lexical tones of Yoruba. Of the three lexical tones (H, M and L), the unmarked M tone was consistent, while the H and L tones had varying perceptual outcomes among the CVA-aphasics. The implication of the finding is that tone recoveries among CVA-aphasics is never the same and, therefore, calls for various linguistic therapies according to each CVA-aphasic case.

Published: October 2021

O estudo objetiva analisar as influências da imigração alemã na formação do sistema religioso de Santa Catarina entre 1840 e 1889, contribuindo para a constituição de uma História Religiosa desse período. Quanto à metodologia, trata-se de uma pesquisa documental, embasada por fontes da Presidência de Província de Santa Catarina, analisados através de referenciais que tratam da imigração alemã para o Brasil no século XIX, considerando aspectos políticos, econômicos e socioculturais associados à colonização. Os resultados evidenciam que a História Religiosa de Santa Catarina é caracterizada pelos diversos arranjos históricos embasados nas ações de indivíduos e de coletivos, vinculadas à emergência de uma infraestrutura à serviço da religiosidade dos diversos segmentos da população, destacando o antagonismo entre as práticas socioculturais de católicos e protestantes luteranos. Mostra-se, ainda, que o sistema religioso constituiu uma estratégia de construção tanto da Província como do Império, relacionado ao engendramento de um espaço público influenciado pela imigração e colonização alemãs.

The Metaphysical Foundations of Physics
Calculation, Bookkeeping, Representation, and Explanation: A Parable
Authors: Maudlin Tim
Published: October 2021

Our topic is a basic discussion of what it is to regard a bit of mathematics as referring to something physical, and the different options one has for explaining —and hence rendering non-miraculous— the empirical success of a mathematical formalism. In order to strip away as much extraneous distraction as possible, we will leave the particular case of the wavefunction in quantum theory aside and tell a simpler tale. A fairy tale, in fact. The aim is to foreground some possible relations between a mathematical formalism and the physical system it is used to represent.

This paper is based on experimental study on bore pile due to vertical loading condition and expressing the behaviour of pile under the vertical incremental loading condition. And in this paper we follow the approach of analytical and experimental.
Social face consciousness and help-seeking behavior in new employees: Perceived social support and social anxiety as mediators
Authors: Wang Chang , Zhang Yuzhu
Published: October 2021

Cultural factors play an important role in new employees' help-seeking behavior (HSB). The relationship between social face consciousness (SFC), as an aspect of traditional Chinese cultures, and HSB has seldom been explored in empirical studies. To examine the potential mediating effects
of perceived social support (PSS) and social anxiety (SA) in the relationship between SFC and HSB, we recruited 682 employees with 1 year or less of experience in the job market to complete the survey. As predicted, SFC had a significantly negative predictive effect on HSB, and the chain mediating
effects of PSS and SA in the relationship between SFC and HSB were significant. The results of the study could be used as a reference for training new employees in learning how to seek help when needed.

Published: October 2021

Introduction: A subset of patients who develop post-surgical heart block
have recovery of atrioventricular-node function. Factors predicting
recovery are not understood. We sought to investigate our center’s
incidence of post-surgical heart block and examine factors associated
with recovery of atrioventricular-node function. Methods: Patients 0 –
21 years who underwent cardiac surgery between January 2010 – December
2019 at a free-standing children’s hospital and experienced
postoperative heart block were included. Demographics, clinical and
operative variables were analyzed. Results: Of 6333 surgical
hospitalizations, 128 (2%) patients were included. Of the 128 patients
included, 90 (70%) had return of atrioventricular-node function, and 38
(30%) had permanent pacemaker placement. Of the 38 patients who
underwent pacemaker placement, 6 (15.8%) had recovery of
atrioventricular-node function noted on long-term follow-up. Median time
to from onset of heart block to late atrioventricular-node recovery was
13 days (IQR 5 – 117). Patients with single-ventricle physiology ( p =
0.04), greater weight ( p = 0.03) and shorter cardiopulmonary bypass
time ( p =0.015) were more likely to have recovery. The use of
postoperative steroids was similar between all groups ( p = 0.445).
Infectious or wound complications were similar between pacemaker groups
( p = 1). Conclusions: Two percent of patients who underwent cardiac
surgery developed postoperative heart block, and 0.6% underwent
pacemaker placement. Early recovery of atrioventricular-node was
associated with greater weight at time of surgery, single-ventricle
physiology and shorter cardiopulmonary bypass time. Late recovery of
atrioventricular-node conduction following pacemaker placement occurred
in 15.8% of patients.

Use of 9.3μm CO2 Laser for Removal of Zirconia Restorations
Authors: Call Grace
Published: October 2021

Objective: The primary aim of this study was to test if a 9.3µm Carbon Dioxide (CO2 ) laser could be used to effectively separate a cemented zirconia restoration from dentin. The secondary aim was to compare shear bond strength (SBS) between RelyXTM Unicem 2 Automix Cement (3M ESPE) (RelyXTM Unicem 2) and RelyXTM Luting Plus Automix Cement (3M ESPE) (RelyX™ Luting Plus). Methods: 40 teeth were prepared to expose dentin and then randomized into four groups of 10 samples. Zirconia slices (non-glazed Yttrium stabilized zirconia samples (2.5 x 3 x 1.5 mm)) were sandblasted with 50 micron aluminum oxide at 30 psi and then cemented onto the dentin samples with RelyX™ Unicem 2 or RelyX™ Luting Plus, dependent on the group. The cements were applied to both the zirconia and dentin with a force of 20 g/mm2 for 30 seconds following manufacturer’s recommendations. After 48 hours, the 9.3µm CO2 laser was used on half the samples for 5 seconds. All 40 zirconia samples were removed with the Instron 5566A in a traditional SBS test. The groups were: 1A - RelyX™ Unicem 2 and Laser, 1B - RelyX™ Unicem 2 and Shear Bond, 2A - RelyX™ Luting Plus and Laser, and 2B - RelyX™ Luting Plus and Shear Bond. The Mann–Whitney U test was used for comparison. Results: Mean SBS of four groups ranged from 0.5 to 4.4 MPa. There was a significant difference in the SBS between 9.3µm CO2 laser and Shear Force methods for RelyX™ Luting Plus. However, the difference between the two methods was not significant for RelyX Unicem 2. RelyX™ Unicem 2 provided significantly higher SBS than RelyX™ Luting Plus for both the CO2 laser and shear force methods (Table 2). Conclusion: The 9.3µm CO2 laser effectively separated the zirconia restoration cemented with RelyX™ Luting Plus from dentin. RelyX™ Unicem 2 provided significantly stronger SBS than RelyX™ Luting Plus.
Comparison of Soviet and post-Soviet Russian settlement systems with the US settlement system, 1959-2020
Authors: Grachev Gennady
Published: October 2021

The lack of discernible changes in the Russian (hereinafter RF) settlement system after the transition from a centrally managed economy to a capitalist economy seems to be contrary to the established view of the exceptional character of capitalist-style settlement systems. To explain this misunderstanding, we compared the state of settlement systems in Russia and in the United States between 1959 and 2020 in this paper. The measures of shape of the Pareto curve were used to quantify the state of the settlement systems: critical exponent, asymmetry coefficient, and Gini coefficient. The study found that the system of settlement in RF territories during the Soviet and post-Soviet periods had the same order and development trend as the system of settlement in US states. The order of urban systems in regions correlates with the local average annual temperatures. The results have led us to conclude that the settlement systems were independent from the economic paradigm.
