The measurement and dynamics of financial openness of Chinese economy
Authors: Zhao Weili
Published: November 2022

Currently there are many literatures examining the linkage between financial openness and other economic factors in emerging economies. Nevertheless, the accuracy of measurement of financial openness is the prerequisite of evaluating its effects. Different scholars usually construct different indicators that capture different facets of financial openness, hence yielding systematically different regression results. Therefore, it is necessary to construct a comprehensive indicator and measure the financial openness in an all-around way. The innovation of this paper lies in the concept of “financial opening facilitation” that is newly put forwarded by the author. This paper constructs a new sub indicator: financial opening facilitation. Different from previous literatures, this paper argues that although some factors are not directly related to financial opening, they can facilitate the operation of financial institutions and support the flow of international capital, so they also play an important role. The author measures the financial openness in terms of financial account openness, financial institutions openness, financial opening facilitation. This brand-new method can be conducive to the further researchers when they examine the relation between financial openness and domestic economy. Furthermore, China's experience of financial opening can give many revelations to other emerging countries.

The subject of the study is the ratio of indicators of success in career and interpersonal relationships of spouses in patriarchal and egalitarian families. The purpose of the study was to determine the direction and nature of changes in marital relations in situations of career growth of one of the spouses. To conduct the study, we used: the questionnaire "Communication in the family" (Yu.E. Alyoshina, L.Ya. Gozman, E.M. Dubovskaya), the methodology "Role expectations and claims in marriage" (A.N. Volkova), the methodology "Distribution of roles in the family" (Yu.E. Alyoshina, L.Ya. Gozman, E.M. Dubovskaya), a test questionnaire of satisfaction with marriage (V.V. Stolin, G.P. Butenko, T.L. Romanova, Faculty of Psychology, Moscow State University), the method "Life Line" Golovakha E.I., Kronik A.A., adapted for the purposes of the study - measuring attitudes to career growth, methods of qualitative and quantitative data processing were also used. The sample of the study is represented by a group of men and women aged 35 to 40 years, in the number of 12 people who have been married for 10-15 years.   Based on the conducted research, it can be concluded that traditional patriarchal families are not characterized by high social activity, focus on career development of both spouses, a high level of trusting communication and mutual understanding. As a result of the correlation analysis, it was found that there are a large number of correlations between various spheres of family relations, satisfaction with marriage and career success. Thus, the data obtained will increase the level of consistency of family values and the role adequacy of spouses, which will reduce the number of conflicts arising in the family and will contribute to the harmonization of family relations and thereby increase the level of satisfaction with marriage by spouses.

The subject of this study is the influence of multimedia on the development of motivation for learning among schoolchildren. A study was conducted on the basis of MBOU Lyceum No. 8 in Krasnoyarsk among students of two ninth grades. In the course of the study, the following methods were used: studying the motivation of M.I. Lukyanova's teaching; determining the level of motivation of N.G. Luskanova's teaching, interviewing teachers and students. Prior to the experiment, the level of motivation among the students of the control and experimental groups was measured, which corresponded to the level of "low" and "medium" for 46 and 52% of respondents, respectively. After the experiment, when more than 100 chemistry and biology lessons were conducted for two quarters, the level of motivation in the experimental group increased according to the indicators "high" and "very high" according to the results of two methods. thus, after conducting an experiment with the use of multimedia technologies in the classroom in the experimental group, there is a decrease in the number of students with low and very low levels of educational motives. The main conclusions of this study are related to the fact that as a result of the study, it was proved that the level of motivation for learning among schoolchildren increases when using multimedia technologies in the classroom, such as multimedia presentations, audio and video clips, electronic textbooks, interactive whiteboards and online testing. The study revealed an increase in academic performance in the experimental group. Academic performance in this group has increased due to an increase in the level of motivation for learning among schoolchildren. According to the results of the study, it can be concluded that the use of multimedia technologies contributes to an increase in the level of motivation for learning and, therefore, directly affects the academic performance of students.

Published: November 2022

This paper presents the experimental verification of the pointing and tracking system of the flight model of an optical communication terminal for small satellites. The terminal, called LaserCube, fits in two CubeSat units and is conceived to operate onboard spacecraft starting from the 6 U (CubeSat units) form factor. The terminal is provided with a dual stage pointing system, composed of a coarse pointing mechanism used to orient the optical head and a fast-steering mirror for the fine pointing of the received and transmitted lasers. The coarse pointing mechanism is based on the parallel platform configuration and alone can provide [Formula: see text] rms pointing accuracy when operating in conjunction with a beacon laser sent by a remote terminal and used for feedback. The control algorithm operates the two pointing stages synergically, targeting an overall pointing accuracy of [Formula: see text] rms while rejecting the disturbances coming from the satellite bus. The pointing system of the LaserCube flight model has been calibrated and experimentally verified in laboratory conditions that replicate real operational scenarios for what concerns the beacon signal attenuation and the disturbances generated by the host satellite. A dedicated setup was used to directly measure the pointing error and asses the system performance.

Histone deacetylases (HDACs) are the target inhibition enzymes in cancer treatment via chemotherapy. Application of this therapeutic technique requires the use of drugs whose side effects are reduced and tiny with necessary safety. In this study, the methods and tools of pharmacophore modeling were used to investigate ten molecules known for their anticancer properties. Particular attention has been given to pinpoint a promising anti-cancer pharmacophore in order to lead new effective inhibitors. Using Discovery Studio 2.5 software, the ten compounds were docked within the active site of the HDAC7 enzyme. Analysis of the binding characteristics of all the compounds collected and tested in the model resulted in the characteristics produced by the 3D pharmacophore of the selected hypothesis. This led to note that the efficiency of any HDAC enzyme inhibitor was related to the characteristics of the designed pharmacophore. At the end, the pharmacophore hypothesis used here was presented as a useful basis for the development of anticancer compounds. Keywords: Pharmacophore, 3c0z, HDAC7, QSAR

Electrochemically generated chemiluminescence (ECL) has attracted significant interest over decades, ranging from fundamental studies of highly efficient electron-to-photon interconversion to practical bioassays. Nonetheless, the ECL efficiency of most emitters is low, which greatly hampers further development. Herein, we report a highly robust carbon nitride film with an unusually boosted ECL efficiency (2256 times higher than that of the reference Ru(bpy)3Cl2/K2S2O8. Double inoculation, which provided the primary interaction of carbon nitride with the substrate and the succedent growth, played a crucial role in preparation. The improved ECL efficiency was ascribed to few pinholes suppressing futile co-reagent reduction, maintenance of more orbit-delocalized heptazine subunit improving ECL kinetics, and transparency avoiding self-absorption. As a result of the exceptionally high ECL efficiency, an ultrasensitive visual DNA biosensor by the naked eye was further successfully developed.
Reagent Prediction with a Molecular Transformer Improves Reaction Data Quality

Published: November 2022

Automated synthesis planning is key for efficient generative chemistry. Since reactions of given reactants may yield different products depending on conditions such as the chemical context imposed by specific reagents, computer-aided synthesis planning should benefit from recommendations of reaction conditions. Traditional synthesis planning software, however, typically proposes reactions without specifying such conditions, relying on human organic chemists who know the conditions to carry out suggested reactions. In particular, reagent prediction for arbitrary reactions, a crucial aspect of condition recommendation, has been largely overlooked in cheminformatics until lately. Here we employ the Molecular Transformer, a state-of-the-art model for reaction prediction and single-step retrosynthesis, to tackle this problem. We train the model on the US patents dataset (USPTO) and test it on Reaxys to demonstrate its out-of-distribution generalization capabilities. Our reagent prediction model also improves the quality of product prediction: the Molecular Transformer is able to substitute the reagents in the noisy USPTO data with reagents that enable product prediction models to outperform those trained on plain USPTO. This allows to improve upon the state-of-the-art in reaction product prediction on the USPTO MIT benchmark.

Published: November 2022

In deze bijdrage ter gelegenheid van het afscheid van prof. dr. Rainer Prokisch als hoogleraar Internationaal Belastingrecht aan Maastricht University, besteden wij aandacht aan het Unierechtelijke verdedigingsbeginsel. Wij hebben als docenten op het gebied van het formele belastingrecht het genoegen gehad vele jaren met Rainer samen te mogen werken bij de capaciteitsgroep Belastingrecht van de Universiteit Maastricht. Rainer heeft als hoogleraar Internationaal belastingrecht een niet aflatende interesse getoond in zowel het Internationale als het Europese belastingrecht. Op het gebied van het Internationale en Europese belastingrecht spelen ook talrijke vraagstukken die zien op het formeel belastingrecht. Voor ons was dat de aanleiding om op een van deze vraagstukken, namelijk de ontwikkeling van het Unierechtelijke verdedigingsbeginsel, in deze bijdrage nader in te gaan. Hiertoe zullen wij eerst beschrijven wat het Unierechtelijke verdedigingsbeginsel inhoudt en wanneer het van toepassing is (paragraaf 2). Vervolgens behandelen wij een aantal kernarresten, te weten Sopropé, Kamino en Datema en Prequ’Italia (paragraaf 3), waarna wij overgaan tot benoeming van het stappenplan (paragraaf 4). Daarna volgt de bespreking van het meer recente arrest van de Hoge Raad van 10 december 2021 (paragraaf 5), om ten slotte de vraag te kunnen beantwoorden in hoeverre het Unierechtelijke verdedigingsbeginsel een beginsel is om rekening mee te (blijven) houden . Wij sluiten af met een conclusie (paragraaf 6).
Offshore indirect transfers: how to convert a legitimate but complex executable taxing right for source states into a balanced situation between source state taxing rights and tax payer rights?
Authors:   Maastricht University, Hurk, van den Prof. dr Hans
Published: November 2022

In my contribution I will discuss offshore indirect transfers (OIT), the reasons for having this subject high on the UN-agenda, the UN proposal, the alternatives developed by the Platform and the possible negative consequences for corporations which are mostly caused by a lack of mandatory dispute resolution and difficult double tax relief due to the fact that more than two states can be allowed to tax capital gains. Tax payer rights seem to deteriorate if these proposals are going to be introduced. Due to the limits in the number of words I will focus on the core issues.
Taxing away foreign subsidies: How pillar two and befit may interfere with national sovereignty
Authors:   Maastricht University, Luja Prof. Dr. R.H.C.
Published: November 2022

In 2022, the regulation of subsidies - including tax incentives - is no longer just a matter of national law, EU state aid law or international trade law. The academic year 2022/2023, in which Prof. Prokisch retires, is also the year in which new tax phenomena start casting their shadow over genuine national incentives, be it tax incentives or otherwise. This contribution will focus on how plans for an EU-wide corporate tax base (‘BEFIT’) and international agreement to secure a minimum level of taxation (‘Pillar Two’) might directly affect the granting of subsidies and tax incentives by EU Member States. This contribution will focus on how to prevent parallel efforts to make the world more sustainable from colliding. Various efforts have been made to raise tax revenue and stop tax avoidance even to a point where such rules may hinder the pursuit of other sustainable development goals (SDGs) such as greening the economy.
Grensoverschrijdende arbeid: always on the move
Authors:   Maastricht University, Weerepas Prof. dr. M.J.G.A.M.
Published: November 2022

In deze bijdrage wil ik het hebben over bepaalde aspecten van grensoverschrijdende arbeid, met het risico dat Rainer het er niet mee eens zal zijn. Grensoverschrijdende arbeid is een weerbarstige materie, met veel tot discussie leidende elementen, zoals de vraag wat tot het salaris in de zin van art. 15, lid 1 van het OESO-Modelverdrag behoort. Deze discussies maken het vakgebied interessant. Op dit moment is de arbeidsmarkt erg in beweging, waarbij nieuwe arbeidsvormen ontstaan. Dat heeft ook een weerslag op de uitgangspunten van internationale belastingheffing en verzekeringsplicht in situaties waarin sprake is van grensoverschrijdende arbeid. Een ontwikkeling die hier kan worden genoemd is het (gedeeltelijk) thuiswerken door grenswerkers als gevolg van de COVID-19 crisis. Het lijkt erop dat het (gedeeltelijk) thuiswerken ook na de crisis al dan niet gedeeltelijk zal voortduren. Een ander fenomeen dat echter al langer bestaat is het zwartwerken. Deze twee elementen leiden tot de volgende vraag: Welke impact hebben de bestaande internationale fiscale regelgeving en sociaal zekerheidsregelgeving op het (gedeeltelijk) thuiswerken door grenswerkers en op zwartwerken? In deze bijdrage komt eerst de toename van arbeidsvormen kort aan de orde. Daarna worden de toepasselijke regels van internationaal belastingrecht en Europees sociaal zekerheidsrecht met betrekking tot het thuiswerken door grenswerkers na de COVID-19 crisis en zwartwerk beschreven. Wat betreft het sociaal zekerheidsrecht is de beschrijving beperkt tot de verzekeringsplicht, ofwel de premieheffing. Afgesloten wordt met een slotbeschouwing.

Although recent advances in gene therapy provide hope for spinal muscular atrophy (SMA) patients, the pathology remains the leading genetic cause of infant mortality. SMA is a monogenic pathology that originates from the loss of theSMN1gene in most cases or mutations in rare cases. Interestingly, severalSMN1mutations occur within the TUDOR methylarginine reader domain of SMN. We hypothesized that inSMN1mutant cases, SMA may emerge from aberrant protein-protein interactions between SMN and key neuronal factors. Using a BioID proteomic approach, we have identified and validated a number of SMN-interacting proteins, including fragile X mental retardation protein (FMRP) family members (FMRFM). Importantly, SMA-linked SMNTUDORmutant forms (SMNST) failed to interact with FMRFM. In agreement with the recent work, we define biochemically that SMN forms droplets in vitro and these droplets are stabilized by RNA, suggesting that SMN could be involved in the formation of membraneless organelles, such as Cajal nuclear bodies. Finally, we found that SMN and FMRP co-fractionate with polysomes, in an RNA-dependent manner, suggesting a potential role in localized translation in motor neurons.
Loss of autism-candidate CHD8 perturbs neural crest development and intestinal homeostatic balance

Published: November 2022

Individuals with mutations inCHD8present with gastrointestinal complaints, yet the underlying mechanisms are understudied. Here, using a stable constitutivechd8mutant zebrafish model, we found that the loss ofchd8leads to a reduced number of vagal neural crest cells (NCCs), enteric neural and glial progenitors, emigrating from the neural tube, and that their early migration capability was altered. At later stages, although the intestinal colonization by NCCs was complete, we found the decreased numbers of both serotonin-producing enterochromaffin cells and NCC-derived serotonergic neurons, suggesting an intestinal hyposerotonemia in the absence ofchd8. Furthermore, transcriptomic analyses revealed an altered expression of key receptors and enzymes in serotonin and acetylcholine signaling pathways. The tissue examination ofchd8mutants revealed a thinner intestinal epithelium accompanied by an accumulation of neutrophils and the decreased numbers of goblet cells and eosinophils. Last, single-cell sequencing of whole intestines showed a global disruption of the immune balance with a perturbed expression of inflammatory interleukins and changes in immune cell clusters. Our findings propose a causal developmental link betweenchd8, NCC development, intestinal homeostasis, and autism-associated gastrointestinal complaints.

Published: November 2022

Introduction. Transport in cities has a huge impact on the environment, the quality of life of people, their health, road safety, etc., which is the subject of a fairly large number of scientific publications. It is obvious that measures aimed at shifting transport demand from a private car towards the use of public transport are extremely relevant. One way to develop such measures could be through a survey of users of transport services.This article reveals patterns in the transport preferences of the inhabitants of the city of Gomel by analysing the results of their transport survey.The purpose of the work is to obtain data on the transport preferences of the inhabitants of the city of Gomel. Materials and methods. When writing the article, materials obtained during the transport survey of residents of the city of Gomel were used. At the same time, graphical analysis methods, crosstabulation tables, Chi-square test (when comparing differences in independent samples of nominal variables), analysis of variance (when comparing differences in independent samples of nominal and numerical variables, depending on the law distributions within groups) implemented in a specialised software product.Results. Based on the results of the article, information was obtained about the transport preferences of the inhabitants of the city of Gomel.Discussion and conclusion. The obtained results of the analysis of the transport survey are the basis for the subsequent justification of measures aimed at shifting transport demand from individual cars towards the use of regular public transport.

Published: November 2022

Introduction. The problems of the organisation of urban passenger transportation are considered. The reasons for the inefficient operation of public transport in the cities of Russia and abroad, as well as the factors contributing to this, are investigated. The insufficient level of information technology systems and technologies use in the transportation process is indicated. The purpose of the work is to develop a refined methodology for evaluating the efficiency of public passenger transport based on the criteria of the information technology indicator, as well as to test the evaluation of the efficiency of motor transport enterprises engaged in passengers transportation in Tambov according to this indicator.Materials and methods. A refined methodology for evaluating the efficiency of public passenger transport has been developed based on the criteria of the information technology indicator. Each criterion was assigned a weighting indicator (coefficient), depending on the significance and impact on the efficiency and safety of public passenger transport.Results. The study of the efficiency of public passenger transport in Tambov according to the criteria of information technology assessment showed that, in general, the level of equipment is lower than the average estimated indicator - from 5.55 to 8.3 points. This indicates the insufficient equipment of carriers with information technologies and systems.Discussion and conclusion. The measures to improve the efficiency of public passenger transport are proposed.
The result of an evaluation for traffic flow characteristics considering the movement of personal mobility equipment by modeling a road traffic section
Authors: Jung A. A. , Shevtsova A. G.
Published: November 2022

Introduction. Today there is an acute problem of increasing the number of accidents involving personal mobility devices (PMD). A sharp increase in these vehicles on public roads poses a threat to both vehicle drivers and pedestrians.Materials and methods. In this article, the results of the evaluation of the traffic flow characteristics of individual mobility devices under different conditions with the help of road section modelling are presented. The aim of the study is to obtain real values of traffic flow characteristics for further analysis and comparison, which in the future will reduce the accident rate with the participation of personal mobility devices. It is suggested a modelling method to be used to analyse the characteristics of traffic flow changing with the introduction of these devices. The objectives of the study are to analyse the number and types of accidents involving personal mobility devices, to identify conflict zones in the interaction of personal mobility devices with other road users, and to select the road environment to be modelled. Both positive and negative aspects of the introduction of PMD in everyday life are presented, and the main types and characteristics of personal mobility devices are briefly considered. Aimsun simulation software was used to create models of a road network section with the introduction of mobility devices in various traffic situations to evaluate their impact on traffic flow.Results. A road section model has been created to automate information processing and to consider different situations of PMD movement in an urban environment, which will allow further comparative analysis to select the safest conditions for the movement of these vehicles.Discussion and conclusions. The use of this modelling method will increase the speed of the study and help to determine most clearly how traffic flow characteristics change in the situations presented.
Prediction of principal stresses due to external load in sans mass considering its mechanical characteristics
Authors: Lunev A. A. , Katsarskiy R. S.
Published: November 2022

Introduction. A part of the methods for designing earthworks and foundations is based on solutions for predicting the stress state of soils under the action of an external load, which do not take into account the structural features of the material. This is in conflict with current studies, which indicate that changes in the moisture content, density, and shape of material particles entail changes in the mechanism of stress state formation. According to some research, when the type of soil, moisture content and density of the mass change, both its mechanical characteristics and the stress state change, which requires consideration in the design of earthworks and building foundations.The method of research. To study the stress state arising in sandy soil with different mechanical characteristics, experimental studies were carried out to determine the pressures in sand of different density and moisture under the action of an external load from a round stamp with an area of 500 cm2. To do this, at a depth of 5, 15, 25, 40 cm along the axis of a round stamp in an array of sand of medium size, mesdoses were set, after which the pressures were measured when the load was applied. For each value of density and moisture created during the experiment, the mechanical characteristics of the sandy soil were determined.Results. The analysis of the existing dependencies for predicting the maximum principal stresses showed that the Kandaurov and Frohlich’s solutions are the only ones that give a connection between the formation of the stress state and mechanical characteristics and allow predicting the minimum principal stresses. The influence of the mechanical characteristics of sandy soil (the angle of internal friction and the modulus of elasticity at different density and humidity) on the Frohlich’s parameter and the distribution capacity coefficient of the medium of the Kandaurov’s solution was established.Conclusion. The analysis of the results of experimental studies made it possible to derive dependencies for predicting the maximum principal stresses of sandy soil at points located at different depths along the axis of a loaded round stamp. The proposed dependencies are a modification of Kandaurov and Frohlich’s solutions, which take into account the relationship between the mechanical characteristics of sandy soil and the parameters of the distribution capacity of the medium.

Authors: Pukharenko Yu. V. , Panteleev D. A. , Zhavoronkov M. I.
Published: November 2022

Introduction. The purpose of the study was to evaluate the effectiveness of dispersed concrete reinforcement in terms of strength and crack resistance.Materials and methods. When conducting research, test methods were used, regulated by the provisions of national standards, equipment specially designed for this study was used.Results. The results of testing fiber-reinforced concretes made using low-modulus and high-modulus fibers are presented.Discussion and conclusions. As a result of the analysis of the data presented, it is shown that in order to assess the effectiveness and the correct choice of reinforcing fibers, it is not enough to characterise fiber-reinforced concrete only by tensile strength in bending. For a more accurate assessment, it is proposed to use crack resistance characteristics, for example, the critical stress intensity factor, or to supplement the description of the advantages of dispersed reinforcement with the features of the behavior of fiber-reinforced concrete under load.

Published: November 2022

Abstract: Conducting analysis in language needs has long been seen essential. Given the importance of Arabic language as the principal language communication in most of the Jordanian universities, this study aims at exploring the difficulties encountered by non-native speakers of Arabic in learning Arabic language. It also seeks to investigating the Arabic language needs among speakers of other languages. The participants of this study include 169 students from four countries (i.e., Malaysia, Thailand, China, and Indonesia). The students were selected from three different disciplines (i.e., Arabic Language, Islamic Finance, and Usuluddin). The study used a questionnaire adapted from previous studies on this topic. The questionnaire contains 49 items: 26 items ask about the difficulties in learning Arabic language, and 23 items ask about the students’ needs in learning Arabic language. The results of this study revealed different difficulties in learning Arabic language. The students also reported their needs to improve their proficiency in Arabic language. The students mentioned difficulties and needs related to productive skills such as writing and speaking. They also reported difficulties and needs to receptive skills but with more focus on the academic context. Based on the results of this study, some recommendations for future research have been provided.

Authors: Bram Barli , Angelina Patricia
Published: November 2022

Writing is a crucial skill and tertiary education students face difficulties in academic writing.  This paper aimed to identify the setbacks or difficulties and the solutions to the setbacks experienced by the Indonesian tertiary education students in academic writing. A survey was used as the method of this study. The data were collected through a questionnaire using a Google form distributed to 26 fifth-semester students taking the Academic Writing course in the English Language Education Study Program of Sanata Dharma University, Yogyakarta, Indonesia, for the academic year 2019/2020. The survey results showed that, in general, the students faced setbacks in, for example, parts of speech, tenses, spelling, prepositions, vocabulary, punctuation, cohesion, discourse markers, writing paragraphs with a clear focus, constructing clear and coherent academic essays, paraphrasing, in-text referencing, and compiling a correct reference list. Concerning academic writing solutions, the results showed that lecturers should be trained and equipped with various writing strategies, feedback on the strengths and weaknesses was vital, and the students needed to improve their organization of ideas, for example. Other solutions were better language skills, language elements, critical thinking skills, paraphrasing, and referencing. Implications of the findings are that students and lecturers would understand and identify common setbacks in academic writing and have opportunities to adopt the suggested solutions to academic writing difficulties.

Authors: Rosmayanti Vivit , Noni Nurdin , Patak Andi Anto
Published: November 2022

This study aims at determining how Performance Expectancy, Effort Expectancy, Social Influence, and Facilitating Conditions influenced Behavioral intentions to use technology in learning English Pharmacy. This study employed a sample of 100 pharmacy students who were enrolled in an English pharmacy course. The samples were chosen using the quota sampling technique. The Unified Theory of Acceptance and Use of Technology (UTAUT) model was performed to measure students' acceptance of the use of technology in this study. The findings of this study indicated that the four aspects mentioned above, such as Performance Expectations, Effort Expectations, Social Influences, and Facilitation Conditions, have a favorable impact on students' Behavioral intentions when using technology to learn English Pharmacy. However, only 40% of the four factors could explain the influence on Behavioral intention. The impact of this study is that it can lead the way and serve as a reference for future research on the UTAUT approach in a larger scope. In addition, the university should be able to increase the benefits and usability of technology as a learning resource by developing its own Learning Management System (LMS), which is easy to use.

Показано, что при синтезе K(hfac) из этилацетатного (EtOAc) раствора K2CO3 и Hhfac, взятых в стехиометрическом соотношении, на промежуточном этапе молекулы EtOAc входят в координационную сферу K+ и образуются кристаллы {K2(hfac)2(EtOAc)}∞. При комнатной температуре EtOAc отщепляется и образуется целевой продукт K(hfac). Двукратный избыток Hhfac приводит к образованию смеси продуктов, в которой присутствуют кристаллы аддукта с водой и гидратированным β-дикетоном {K2(H4hfpt)2(hfac)2(H2O)}∞ (H4hfpt = 1,1,1,5,5,5-гексафторпентан-2,2,4,4,-тетраол). Медленная кристаллизация Rb(hfac) в Г-образной ампуле в хлороформе при 35-40°С приводит к формированию кристаллов {Rb3(hfac)2(CF3COO)(ttpt)}∞ (ttpt = 2,4,6-трис(трифторметил)тетрагидропиран-2,4,6-триол), а при кристаллизации в 1.1 M капле раствора NaCl найдены кристаллы {Na2Rb(hfac)3}∞. Методом термогравиметрии показано, что гексафторацетилацетонат рубидия термически менее стабилен, чем аналогичные комплексы калия и цезия.

Poly lactic acid or poly lactide (PLA) is a natural polymer that is biodegradable, thermoplastic and is an aliphatic polyester made from renewable materials such as young kepok banana starch. Poly lactic acid with the chemical formula CH3CH(OH)COOH is a biodegradable polymer obtained from the combination of lactic acid monomers. Therefore, in this study the PLA polymer as a matrix was added with fillers in the form of Coir and Chitosan. Coir is a coconut fiber that has been widely used by researchers for decades. Chitosan has been widely used as an important and promising biopolymer material in tissue engineering because of its anti-microbial activity, biodegradability, biocompatibility, and non-toxicity. The characteristics resulting from the combination of these three materials resulted in 4 samples, namely the fixed variable PLA with variations of Coir and Chitosan. Sample 1 Coir/Chitosan ( 90:10 (%)) produces a tensile strength value of 80 MPa. Sample 2 Coir/Chitosan (80:20 (%)) yielded a tensile strength of 55 MPa. Samples of 3 Coir/Chitosan (70:80 (%)) yielded a tensile strength of 48 MPa. Samples of 4 Coir/Chitosan (60:40 (%)) produced a tensile strength of 30 MPa. The FTIR test on sample 1 resulted in a new compound found in the PLA/Coir/Chitosan composite, namely the compound N=C=O which is an isocyanate group at the peak of the 2279.86 cm-1 group. While the SEM test which shows the physical structure of the sample composition of PLA with the addition of Coir/Chitosan (90:10%) is the sample with the best morphology.

As part of ARL’s Research Library Impact Framework initiative, a team from the University of Pittsburgh Library System conducted a study to understand the information-seeking behavior of early-career faculty in the hard sciences. The team sought to learn how those faculty discover published content and if they use library-purchased commercial databases in the process. Additionally, the team wished to understand how much time and effort researchers invest when looking for content and what pain points they experience. Another objective of this project was to develop and evaluate a methodology for collecting and analyzing information about the library’s role in the research discovery process, for any part of the research life cycle. Thus, the results will guide library services, as well as shed light on ways libraries can support researchers in research discovery.

A automação no setor agrícola visa aperfeiçoar o manejo dos insumos e recursos naturais a serem utilizados, evitando o consumo desnecessário. O presente trabalho busca colaborar com a problemática do correto uso da água ao simular, na plataforma de simulação TinkerCad, a automatização de um sistema de irrigação controlado por um microcontrolador Arduino. O projeto baseou-se na plataforma Arduino por ser um sistema amplamente utilizado, de código aberto e baseado em hardwares e softwares práticos de serem aplicados. O sistema de irrigação foi desenvolvido utilizando uma placa Arduino Uno R3, uma válvula solenoide, que na simulação foi substituída por uma lâmpada, e um sensor de umidade, que também foi substituído por um potenciômetro. Substituições necessárias devido à ausência desses componentes na plataforma TinkerCad. Três LEDs foram utilizados para sinalizar o nível de umidade do solo. Um circuito divisor de tensão foi utilizado para indicar a variação de umidade no solo. Também foi utilizado um voltímetro para facilitar as simulações do sensor de umidade. O funcionamento do sistema baseia-se no controle de uma válvula para irrigação em função dos níveis de umidade do solo: seco, indicado pelo LED vermelho; ideal, indicado pelo LED verde; e encharcado, indicado pelo LED azul. O potenciômetro simula a variação de tensão em um sensor de umidade a ser lida pelo Arduino. Em função desse valor de tensão, o programa desenvolvido identifica o nível de umidade do solo e controla a abertura ou fechamento da válvula de irrigação, representada pela lâmpada. Os resultados do projeto foram satisfatórios, considerando que o sistema desenvolvido foi capaz de simular a análise da umidade do solo e controlar adequadamente a válvula responsável pela rega. O presente trabalho proporcionou aprendizado quanto ao desenvolvimento de sistemas de automação, de programação na plataforma Arduino e de simulação.

A saúde mental do idoso é um tema que precisa adquire relevância científica, pois estas pessoas
cada dia mais vêm adoecendo com problemas mentais. O presente trabalho analisou produções
científicas publicadas entre 2018 e 2022, nos sites da BVS, Scielo e Periódicos da Capes, com vista a identificar principais causas dos problemas mentais relacionados ao idoso. Trata-se de uma revisão sistemática integrativa. Os descritores estruturados no DeCS e MeSH. O período de coleta dos dados correu no mês de setembro de 2022. Adotaram-se como critérios de inclusão artigo de científicos. Enquanto os critérios de exclusão foram artigos que não contemplam a temática em saúde mental do idoso. Espera-se que com novos estudos ocorro um novo olhar direcionado a promoção da saúde mental dos idosos.

In line with what is defined by W.H.O. (World Health Organization) the objective of the work is to observe and define the interconnection between a healthy lifestyle and the quality of life perceived by people. For this purpose, 30 healthy subjects, who had never practiced sports at a competitive level, were recruited. All individuals were evaluated at T0 and T1 through clinical evaluation and specific functional tests to define the psycho-physical well-being of the person. For three months they were followed with a personalized diet. Subjects were divided into two randomized groups: group A called experimental that followed the protocol for the duration of the study, and group B said evaluation group that performed only evaluations at the same time as group A. both groups were evaluated twice, the first immediately after the last training session, the second evaluation was performed after 30 days from the first. The objective of the project was to analyze, after three months, the cognitive changes in memory and concentration skills, stress experienced at work or study, and psycho-physical well-being perceived by interested parties. The data collected during the evaluations showed that the interconnection between a healthy lifestyle and the quality of life perceived by people is evident.

É finalidade destas linhas examinar, de modo conciso, algumas contribuições que a Filosofia e Teologia modernas podem oferecer para a intelecção do problema da pessoa de Cristo, a fim de obter melhor compreensão do dogma de Calcedônia.

Poderíamos dividir toda a problemática sobre a pessoa de Cristo em três momentos, que não são rigidamente definidos historicamente, mas antes momentos de intelecção: I. Momento de uma perspectiva funcional; II. Momento de uma intelecção ontológica; III. Momento de uma intelecção temático-ontológica...

O objetivo do presente artigo foi de verificar se a relação corpo e formação humana se encontra presente no contexto da sociedade contemporânea como tema investigativo na produção do conhecimento atual. A proposta desse estudo é decorrente dos diálogos estabelecidos entre os grupos de pesquisa Laboratório de Estudos Corporais – LEC/Unespar e Grupo de Estudo e Pesquisa em Linguagem Corporal e Diversidade – GEPL/UFGD, cujas inquietações balizaram a proposição do curso de extensão Corpo, Formação Humana e Sociedade que teve como objetivo promover diálogos e reflexões interinstitucionais acerca das diferentes concepções de corpo e seus desdobramentos nas práticas corporais contemporâneas. Para a realização da pesquisa, propõe-se um levantamento das produções da pós-graduação brasileira que abordassem os temas: corpo, formação humana e sociedade. Como metodologia, adotou-se o estado do conhecimento conforme procedimentos indicados por Marilia Costa Morosin. Por meio do levantamento realizado, pode-se verificar que a Pós-graduação brasileira tem produzido estudos com a temática corpo, formação humana e sociedade evidenciando o crescimento expressivo no período entre os anos de 2001 e 2010. Esses resultados nos possibilitam entender que “corpo e formação humana” é uma temática que demanda discussões, reflexões e estudos para a construção de um conhecimento basilar na formação dos sujeitos no contexto da sociedade contemporânea.
