Authors: Thi Hai Ha Nguyen , Thủy Dinh Thi Thu , Hang Tran Thi , Trang Nguyen Thi Thuy
Published: June 2022

The worldwide adoption of the International Financial Reporting Standards (IFRS) is occurring rapidly to improve the quality of accounting information through the use of a set of standardized accounting rules. In that context, Vietnamese enterprises are switching from the Vietnam Accounting Standards to the International Financial Reporting Standards in preparing their financial statements. This transformation generates both opportunities and challenges for Vietnamese businesses. This research carries out literature reviews and in-depth interviews with some researchers and experts to identify what difficulties Vietnamese businesses are facing in transforming financial statement standards and to propose lessons learnt for other businesses that are preparing for the transformation. Besides, the research also compares a big enterprise’s financial statements prepared under VAS versus IFRS as a case study to point out some differences between the two accounting standards.

Authors: Hanh Nguyen Thi Van , Dut Vo Van
Published: June 2022

The article studies the impact of bank liquidity and bank stock liquidity on the stock price volatility of 17 The article studies the impact of bank liquidity and bank stock liquidity on the stock price volatility of 17 commercial banks listed on the Vietnamese Stock Exchange. The study uses the Random Effect Model with unbalanced table data and quarterly frequency from the first quarter of 2006 to the fourth quarter of 2020. The results show that the financial gap (FGAP) has a positive impact on the stock price volatility of banks, meaning the higher the financial gaps, the lower the bank liquidity, and the larger the stock price volatility of banks. In addition, the study also shows that the size of total assets and the change of exchange rate for the two factors have opposite effects on changes in the share prices of banks. The study has not yet found any evidence to conclude that stock liquidity has an impact on the stock price volatility of the commercial banks listed on the Vietnamese Stock Exchange.

The Impact of Enterprise Risk Management and Sustainability Reporting on Business Performance of Listed Enterprises on Vietnam Stock Market
Authors: Anh Nguyen Thuy , Hoa Tran Phuong
Published: June 2022

Enterprise Risk Management (ERM) is becoming a critical issue in the current dynamic environment where organizations have been exposed to more risks from different perspectives. Additionally, Sustainability Reporting also emerges as one of the burning topics in recent management literature. This paper examines whether ERM implementation and Sustainability Reporting could bring any effect on the business performance of Vietnamese listed companies. The paper constructs the index to measure the level of ERM implementation of listed firms in Vietnam and uses the generalized least square method (GLS) to analyze the impact of these two concerns on business performance. The regression results indicate that there are significant positive relationships between ERM as well as Sustainability Reporting and the business performance of listed companies on the Vietnam stock exchange over the period 2016-2019. The result strengthens the previous studies that companies with more sustainability disclosure and more efficient ERM implementation are likely to be better in terms of financial performance and market performance. Moreover, there is growing support for the argument that companies will improve their performance by employing the ERM concept and enhancing sustainability transparency to stakeholders.

Financial Development and Renewable Energy Consumption - Empirical Evidence in Southeast and East Asian Countries
Authors: Chien Nguyen Van
Published: June 2022

Climate change is one of the biggest challenges in our times. Climate change is happening such as rising in temperatures and sea level, drought, the destruction of the ozon layer. Climate change is consistent with a higher level of carbon dioxide that negatively affects human health and the economy. To mitigate the climate change, countries must reduce the emissions linked to the human activities in order to protect the earth safe as well as maintain economic growth in the context of sustainable development. In this case, renewable energy consumption is one of the most effective tools in the form of fighting against climate change. The purpose of the study is to evaluate the impact of financial development on renewable energy consumption in six Southeast Asian countries (i.e. Vietnam, Indonesia, Malaysia, Thailand, and the Philippines) and three East Asian countries (i.e. China, Korea, and Japan). Using the generalized least squares method, the research results confirm that financial development has a negative impact on renewable energy consumption. The research results also find negative effects of inflation and urbanization rates on renewable energy use. Finally, economic growth and lending rates have no impact on renewable energy in the East and Southeast Asian countries.

Published: June 2022

The objective of this study was to develop an influential model of work behavior encompassing the emotional intelligence, personality, and work environment of village health volunteers working under outbreak circumstances, with psychological capital as a mediator, during the COVID-19 pandemic in Thailand. A cohort of 425 village health volunteers (VHVs) was included in the research conducted in lower northern central Thailand. The data were analyzed using descriptive and inferential statistics, namely confirmatory factor analysis, correlation coefficients, and structural equation modeling. The results reveal that the measurement model fitted with the empirical data of χ2 = 119.78, df = 106, p = .17, CFI = 1.00, NNFI = 1.00, GFI = .98, AGFI = .93, RMSEA = .01, and χ2/df = 1.13. These findings indicate that psychological capital influenced the personality of VHVs. Furthermore, the work behavior of VHVs was also significantly influenced by EQ and the working environment (p = .01). Local administration and healthcare agencies should promote a conducive work environment and EQ to enhance VHVs’ psychological capital and work behavior for unanticipated crises in the future.

Effect of Commercial Grade Malathion on Immunological Responses in Mice infected with Staphylococcus aureus
Authors: Pinto Janita , Bernhardt Grisilda Vidya , Kavitha Liegelin
Published: June 2022

The pervasive use of organophosphorus compounds as pesticides in recent years has posed a major threat to the population especially to the occupational workers. Once developed as a chemical warfare in the early 1940’s and having been used in World War II as nerve toxic agent, it has gained entry to almost every household worldwide. Malathion, the OP insecticide was first registered for use in 1956 in the United States. The deleterious effects of Malathion are less studied and have been intriguing to the researchers. The current study focused on the immunosuppressing effect of Commercial Grade Malathion (CGM) on normal and infection induced mice assayed by three immunological markers the Adenosine Deaminase (ADA) levels, Hemagglutination titer (HA) and Carbon Clearance index (CCI). A comparative study was made on normal and subcutaneous Staphylococcus aureus (SA) infected mice exposed to 5% LD50 of CGM. The results obtained showed adverse effect on immunological response in mice that were exposed to CGM alone and in mice exposed to CGM plus subcutaneous S. aureus infection. The effect of CGM was observed by an increase in ADA, decrease in antibody-producing capacity in HA assay and decrease in carbon clearance capacity being greater in the CGM plus subcutaneous SA infection group. This indicates that immunosuppression by pesticide chemicals may be greater in different pathological conditions like an infection in which the immune status is compromised.
Reconstructive plastic surgery in patients with complex defects and deformities of the head when removing extracerebral tumors extending beyond the cerebral skull
Authors: Morozov Tenhiz А. , Kvasha Michail S.
Published: June 2022

Objective: To improve the surgical results of neurosurgical patients with complex defects and deformities of the head based on modern innovative technologies.
Маterials and methods. Based on the analysis of diagnosis and surgical treatment of 54 patients with common extracerebral tumors of the head the issues of optimizing their treatment were considered. The positive role of reconstructive-plastic operations in complex defects and deformities of the head on the basis of modern possibilities of computer modeling and use of arterial autografts is noted.
Results. Carrying out computer simulations before the operation, radical removal of the tumor with a single-stage reconstructive-plastic operations with the use of innovative technologies provides high efficiency of treatment, satisfactory quality of life of patients.
Conclusions. Reconstructive plastic surgery in patients with complex defects and deformities of the head when removing extracerebral tumors that extend beyond the cerebral skull, can provide a satisfactory functional and cosmetic effect of the operation. Radical removal of the tumor by a single-stage autologous tissue grafting using modern technologies promotes rapid wound healing and good quality of life. In patients with widespread cancer stages of the skull, for the plasty of complex soft tissue defects of the cranial vault, the optimal operation is the use of regional musculocutaneous flaps. The type, shape and required amount of the tissue depends on the size and location of the defect. It has been confirmed that the use of a horizontal D-shaped musculocutaneous flap is justified for temporal and parietal defect plasty, and the use of a vertical D-shaped musculocutaneous flap is required to close the occipital-parietal defect. The use of computer simulation is effective and appropriate in patients with large defects and deformities of the cerebral and facial skull when planning complex reconstructive plastic surgery. The use of modified surgical approaches, the latest innovative technologies has made it possible to significantly improve the quality of life of patients, contributed to their early rehabilitation and readaptation.
COVID-19: infection and neurological complications
Authors: Lisianiy Mykola I. , Pedachenko Eugene G.
Published: June 2022

The issues of neurological complications after coronavirus disease 2019 (COVID-19) are highlighted, since coronaviruses affect not only the respiratory system but also other organs and systems of the body, notably they can cause neurological disorders and diseases. There is little evidence for a direct mechanism of SARS-CoV-2 virus neuroinvasiveness and neurotoxicity. Various mechanisms of coronavirus invasion into the brain are discussed - anterograde and retrograde, neuronal spread, transcriptional and hematogenous pathways. Retrograde / anterograde transport and transsynaptic transmission of the virus have been confirmed by in vitro studies, notably SARS-CoV-2 can enter the central nervous system through olfactory nerve receptor cells. Once in the olfactory bulb, the coronavirus can spread to the cortex and other brain structures, in particular the hippocampus and spinal cord. Invasion of the virus into the central nervous system is also possible by spreading along peripheral nerves, such as along the vagus nerve, which innervates the lungs and intestines. The virus invasion into the central nervous system through the blood-brain barrier is considered to be one of the most frequent routes. There are several possible mechanisms for the spread of SARS-CoV-2 across the blood-brain barrier (circulation of viral particles in the bloodstream, viral transcytosis through vascular and capillary endothelial cells, infection of leukocytes with viruses and their transmission of viruses across the blood-brain barrier ("Trojan horse")). However, there is no robust evidence of CNS infection with SARS-CoV-2. Hypoxia induced by the cytokine storm and respiratory distress lead to the impairment of brain metabolism and neurological complications development. There is an ongoing debate as to whether neurological disorders are primary neurological symptoms or secondary consequences of acute respiratory distress syndrome and inflammation.
Among the large number of disorders of the nervous system, there are five main types with long-term neurological complications associated with COVID-19: 1) encephalopathy with delirium / psychosis, 2) inflammatory syndromes of the central nervous system, including encephalitis, myelitis, acute disseminated encephalomyelitis, 3) ischemic strokes (half of them with pulmonary embolism), 4) peripheral neuropathies, Guillain-Barré syndrome and brachial plexopathies, 5) other disorders of the central nervous system.
Incompleteness or inconsistency of statistical data on neurological complications after infection was noted. Further study is required of all early and long-term manifestations of neurological disorders and diseases in mild and asymptomatic manifestations of infection, acute and long COVID-19 and after vaccination.

Published: June 2022

Objective: to analyze the results of using various methods of plastic closure of bone defects of the anterior cranial fossa (ACF) floor when removing craniofacial tumors of the ACF floor depending on the size of the defect.
Materials and methods. A retrospective analysis of treatment outcomes of 122 patients with craniofacial tumors of the ACF floor was carried out. According to the nature of the lesions malignant craniofacial tumors were detected in 98 (80.3%) patients, and benign ones in 24 (19.7%) patients. The following neurosurgical approaches to craniofacial tumors of the ACF floor were used: bifrontal - in 58 (47.5%) patients, subcranial - in 49 (40.2%), transbasal Derome - in 8 (6.5%), frontotemporal - in 4 (3.25%), expanded endoscopic - in 3 (2.45%). In 52 (42.6%) cases, endoscopic endonasal assistance was used, most often in the case of plasty of large ACF floor defects to revise the surgical defect, assess the sufficiency of plasty and tamponade of the nasal cavity with balloon catheters.
Results. Patients were divided into groups depending on the bone defect of the ACF floor: median - in 27 (22.1%), middle-expanded - in 71 (58.2%), middle-lateral - in 24 (19.7%). The following types of plasty of the bone defect of the ACF floor were used: pedicle flap - 83 (68.0%) cases, free flap - 22 (18.1%), pedicled periosteal flap with reinforcement - 17 (13.9%). Postoperative complications occurred in 17 (13.9%) patients: nasal liquorrhea in 10 (8.2%) patients (of which 6 underwent reoperation to eliminate it), in 7 patients it was complicated by meningoencephalitis, in other 7 (5.7 %) - meningoencephalitis without signs of nasal cerebrospinal fluid. Postoperative mortality was 0.71% (1 patient). The frequency of nasal cerebrospinal fluid in the group of plasty using a free flap was 13.6% (3 cases), meningoencephalitis - 4.5% (1 observation), in the group of plasty using pedicle flap - 4.8% (4 cases) and 6.0% (5 observations), in the group of plasty using a pedicle flap with reinforcement - 17.6% (3 cases) and 11.7% (2 observations). In 33 (27.1%) cases the use of the author's method of bone defect plasty of the ACF floor with duplication of complications were not registered.
Conclusions. Significant size and spread of bone defects of the ACF floor increase the risk of postoperative complications. The use of free flaps for plasty of the bone defect of the ACF floor is ineffective and is associated with a high risk of complications. The proposed method of plasty of the posterior parts of the ACF floor by duplication of the periosteal flap promotes the sealing of the posterior parts, where suturing causes certain difficulties. Reinforcement of plasty from the side of the nasal cavity due to endoscopic technique using tamponade or balloon catheters reduces the incidence of postoperative complications.

Published: June 2022

Photoionization is a process taking place on attosecond time scales. How its properties evolve from isolated particles to the condensed phase is an open question of both fundamental and practical relevance. Here, we review recent work that has advanced the study of photoionization dynamics from atoms to molecules, clusters and the liquid phase. The first measurements of molecular photoionization delays have revealed the attosecond dynamics of electron emission from a molecular shape resonance and their sensitivity to the molecular potential. Using electron-ion coincidence spectroscopy these measurements have been extended from isolated molecules to clusters. A continuous increase of the delays with the water-cluster size has been observed up to a size of 4-5 molecules, followed by a saturation towards larger clusters. Comparison with calculations has revealed a correlation of the time delay with the spatial extension of the created electron hole. Using cylindrical liquid-microjet techniques, these measurements have also been extended to liquid water, revealing a delay relative to isolated water molecules that was very similar to the largest water clusters studied. Detailed modeling based on Monte-Carlo simulations confirmed that these delays are dominated by the contributions of the first two solvation shells, which agrees with the results of the cluster measurements. These combined results open the perspective of experimentally characterizing the delocalization of electronic wave functions in complex systems and studying their evolution on attosecond time scales.

Published: June 2022

Charge transfer and subsequent separation into free carriers are key processes that govern the efficiencies of third generation solar cell technologies based on donor-acceptor heterojunctions. As these processes typically occur on picosecond to femtosecond timescales, it is necessary to employ ultrafast spectroscopic techniques to further our understanding of these processes in order to provide vital information that can aide in furthering material design. Within the framework of the National Centre of Competence in Research “Molecular Ultrafast Science and Technology” (NCCR MUST), we have developed and utilized a suite of different ultrafast spectroscopic techniques to study charge generation, separation and recombination in a variety of small molecule based organic solar cells and lead halide perovskites. Here, we provide an overview of the main techniques used in our laboratory and the recent results obtained using these spectroscopic techniques.

Singkawang City West Kalimantan Province has one of the natural attractions of the beach is Batu Burung Beach. The attraction of this object is the panorama of the beach with granite stones which is based on the history as the gathering place of birds. The attraction of Batu Burung Beach has not been the main destination for tourists, because it has not been developed properly and realized optimally. The factor that hinders the development of tourist attractions is marketing so that not many tourists know about the existence of this attraction. This research purposed to analyse the potential of supply and demand tourist attractions Batu Burung Beach. The research method used is quantitative method and supported by qualitative method. The analysis method that used to analyse potential supplies is ODTWA analysis, while to analyse potential demands is using descriptive analysis. The results of research on Batu Burung Beach attractions show that it is worth developing as a beach tourist destination. Based on the recapitulation of the value of potential objects and tourist attractions, the beach got a potential value index of 77.33% which falls into the category worth to be developed. The criteria that requires follow-up actions so that this object can be in priority scale and developed into a beach tourist attraction is marketing. While the potential demand criteria that require follow-up actions is the need for the expansion of tourist attraction areas, widening of the entrance, procurement of sign boards, the addition of shelters, the expansion of toilets and prayer rooms, the addition of food stalls, and the procurement of social media and information brochures. Batu Burung Beach tourism object with this handling is expected to be developed into an alternative beach tourist destination in Singkawang City.
EFFECT OF USING LEAD RUBBER BEARING ON A STEEL ARCH BRIDGE
Authors: Kusumastuti Dyah , Lim Erwin - , Asneindra Mario , Mulyadi Silvester Sandy
Published: June 2022

A study was conducted to evaluate the application of Lead Rubber Bearing (LRB) on bridge structures. The length of steel arch bridge is 80 m, width of 10 m, and height of 19.6 m. The bridge is simply supported with two bearings on each support. Structural analysis reveals that the lateral force on the bearing is more than 400 tons (835 tons in longitudinal direction). The original designer’s intention is to use pot bearings. However, the pot bearing was required to undergo some mechanical test to verify its properties prior to installation. Due to its size, this scheme is not applicable due to the limitations of the testing facility. Therefore, an alternative design was evaluated using LRB to reduce the reaction force, hence downsize the bearing size. The LRB used is of LRB 7500 characteristics, and the calculation refers to AASHTO Guide Specifications for Seismic Isolation Design (GSID), 4th edition 2014.The analysis shows that applying LRB on the bridge lengthened the structural period from 0.76 seconds to 1.67 seconds. It also increased the damping ratio from 5% to 43 %. With these significant changes in structural parameters, lateral forces due to earthquake loads on the bearing and foundation can be greatly reduced. The study found that replacing pot bearings with LRBs can reduce the lateral force to 80 tons, approximately one fifth from the previous design. Correspondingly, the internal forces of some major structural components of the bridge can be reduced due to the application of LRB.

Theoretical Investigation of Knowles Hydroamination Based on Systematic Exploration of Oxidation/Reduction Pathways for Photoredox-Catalyzed Radical Process
Authors: Harabuchi Yu , Hayashi Hiroki , Takano Hideaki , Mita Tsuyoshi , Maeda Satoshi
Published: June 2022

Systematic exploration of reaction paths based on quantum chemical calculations revealed the entire mechanism of Knowles’s light-promoted catalytic intramolecular hydroamination via radical processes. Bond formation/cleavage competes with single electron transfer (SET) from the catalyst/substrate to substrate/catalyst. All these processes were theoretically described by reactions through transition states in the same electronic state and non-radiative transitions through the seam of crossings (SX) between different electronic states. This study determined the energetically favorable reaction path by combining the reaction path searches and the SX geometry searches, and then discusses the entire reaction mechanism. Such a calculation was achieved by establishing a novel computational approach that represents SET as a non-adiabatic transition between substrate's PESs for different charge states adjusted based on the catalyst's redox potential. Finally, we uncovered the whole picture of the reaction process, in which N atom of the substrate is oxidized by photoredox catalyst via SET, the resulting aminium radical is added to alkene, and the hydroamination product is produced after SET process accompanying protonolysis with MeOH. The present calculations showed that the reduction and proton transfer proceed concertedly. Also, in the reduction process, there are SET paths leading to both the product and the reactant, and the redox potentials of the catalyst change the contribution of the SET path leading to the product.
First and Second Sphere Interactions Accelerate Non-Native N-Alkylation Catalysis by the Thermostable, Methanol-Tolerant B12-Dependent Enzyme MtaC
Authors: Kumar Amardeep , Yang Xinghan , Li Jianbin , Lewis Jared
Published: June 2022

During efforts to explore the range of reactions catalyzed by the previously-engineered B12-dependent enzyme CarH*, we found that this enzyme catalyzes N-alkylation of aniline using ethyl diazoacetate but that B12 itself provides only trace conversion for this reaction. This observation suggested that the unique primary and second coordination sphere provided by CarH* accelerates non-native N-alkylation catalysis and that other B12-dependent proteins could provide further improvements in activity. We used a structural homology search to identify the corrinoid protein MtaC, which was reconstituted with B12 to generate a catalyst with significantly-improved aniline N-alkylation activity on a range of substrates. MtaC also displays remarkable thermal stability and organic solvent tolerance, remaining folded even in pure methanol. These results highlight how protein scaffolds can be used to impart new activity and other beneficial properties to metal catalysts and suggest that MtaC could serve as a useful platform for non-native B12 catalysis.

Published: June 2022

Herein we introduce a new and straightforward notation for identifying stacking sequences in high-symmetric honeycomb lattice layered materials. The Joining and Arrangement of Multilayers (JAM) notation assigns a string of characters to the structure of a polytype using only its chemical symbols. A pair of basic rules based on the symmetry is enough to identify those JAM strings that provide unique polytypes (canonical JAMs). This notation is the first step in transcribing layered materials into a series of characters for more accurate identification of stacking sequences.
Multistate, polarizable QM/MM embedding scheme based on the direct reaction field method: Solvatochromic shifts, analytic gradients and optimization of conical intersections in solution
Authors: Humeniuk Alexander , Glover William J.
Published: June 2022

A polarizable embedding scheme is presented that accounts for differential solvation of ground and excited states in QM/MM simulations. The polarization and dispersion interactions between the quantum-mechanical (QM) and molecular-mechanical (MM) regions are described by the direct reaction field (DRF) Hamiltonian, while the Pauli repulsion between explicitly treated QM electrons and the implicit electron density around MM atoms is modeled with effective core potentials. A single Hamiltonian is used for all electronic states, so that Born-Oppenheimer states belonging to the same geometry are orthogonal and state crossings are well-defined. The method is implemented in TeraChem, where it is combined with multiple electronic structure methods, including Hartree-Fock, Configuration Interaction Singles, and Complete Active Space Self-Consistent Field. In contrast with older implementations of the DRF method, integrals of the polarization operators are evaluated exactly. Expressions for ingredients needed to construct analytical gradients and non-adiabatic coupling vectors are derived and tested by optimizing a conical intersection between two excited states in the presence of a polarizable solvent shell. The method is applied to estimating the solvent shifts of absorption energies of a series of donor-acceptor dyes having low-lying charge transfer states. Even for a non-polar solvent such as n-hexane the inclusion of its static polarizability leads to non-negligible shifts that improve the agreement with the positions of experimental absorption maxima measured in solution.
aperçu des marrons aux Amériques
Authors: Price Richard
Published: June 2022

Le marronnage était une forme de résistance capitale pour les esclaves, qu’elle fût entreprise par des individus seuls, par des petits groupes, ou dans de grandes rébellions de masse. Partout, des communautés marronnes se dressaient comme des défis héroïques devant l’autorité coloniale, comme preuves vivantes de l’existence d’une conscience esclave, qui refusait d’être limitée par la conception ou la manipulation des Blancs.
Pendant plus de quatre siècles, des communautés fondées par des esclaves auto-libérés se sont répandues aux marges de l’Amérique des plantations du Brésil au sud-est des États-Unis, du Pérou au sud-ouest des États-Unis. Connues en espagnol sous le nom de Palenques et en brésilien comme quilombos ou mocambos, ces nouvelles sociétés étaient d’échelles diverses : minuscules bandes éteintes en moins d’une année ou puissants États comptant des milliers de membres, se perpétuant sur des générations voire des siècles. Cette étude a pour objectif de présenter le marronnage et les Marrons aux Amériques, dans tous les territoires et toutes les langues et permettre de comprendre les raisons pour lesquelles le marron est érigé en héros dans les espaces anciennement colonisés.

Лавина слов - явление, характеризующее кинотексты современной массовой культуры, - рассматривается с точки зрения синтактики и семантики как уровней кинематографического семиозиса, которые необходимо учитывать при выборе наиболее эффективного способа ее перевода.

The word avalanche is a peculiar trait of polymodal texts of modern mass culture. It is characterized in terms of its formal, semantic and pragmatic aspects which, together with the polymodal context, must be taken into account when choosing the most effective translation technique.
PROXEMES AS MARKERS OF THE NON-VERBAL CODE IN THE PUBLICISTIC DISCOURSE OF THE JOURNALISTS IN THE NEW YORK TIMES
Authors: Трофимова Наталия Алексеевна
Published: June 2022

В статье приведены результаты исследования тенденций употребления проксем как маркеров невербального кода в публицистическом дискурсе журналистов The New York Times Марка Лендлера, Дэна Билефски, Эллен Барри и Сары Лайл. Установлено, что количество проксем в статьях обусловлено темой статьи и не зависит от объема статьи. Определено, что проксемы чаще используются в статьях журналистов Марка Лендлера и Дэна Билефски, чем журналисток Эллен Барри и Сары Лайл, что свидетельствует о гендерном влиянии на частотность употребления проксем в публицистическом дискурсе.

The article presents the results of a study of trends in the use of proxemes as markers of non-verbal code in the mass-media discourse of The New York Times by such journalists as Mark Landler, Dan Bilefsky, Ellen Barry and Sarah Lyall. It was found that the number of proxemes in articles is determined by the theme of the article and does not depend on the volume of the article. It was determined that proxemes are more often used in articles by male-journalists as Mark Landler and Dan Bilefsky than by female-journalists Ellen Barry and Sarah Lyall, which indicates a gender influence on the frequency of using proxemes in mass-media discourse.
Innovations in the field of urban public transport and prospects of implementing new mobility principles
Authors: Malyshev M. I.
Published: June 2022

After analyzing the global causes of the radical changes in transport mobility that occurred earlier, the goal was set up to extract current trends that may affect the change in passenger mobility principles. The study revealed that theoretically the transport process can be divided into passive and active phases, and descriptions of the components of these processes were given. It was noted that the modern concept of the transport Mobility-as-a-Service (MaaS) is characterized by such elements as safety, comfort, time, information and cost. The description of the elements, including operational, transport and environmental safety, accessibility and quality of the transport process, was given. The guidelines to ensure new mobility were established, such as the electrification of transport, including the distribution of electric buses, the implementation of artificial intelligence and the Internet of Things tools into the process of managing passenger transport by means of telematics systems, the advancement of unmanned vehicles. In terms of new mobility by using the concepts of abandoning to use personal transport in favor of public transport, developing a unified system for planning routes and purchase of tickets, the trend of redistributing loads on public transport in the context of new MaaS was described. This system implies the use of not only mass and main modes of transport, but also all the available vehicles for transporting passengers in the process of multimodal transportation. The idea of abandoning to use personal transport in favor of public transport was described, and the main tools for stimulating such a choice were stated. The signs of “smooth” and “seamless” transportation were described. In order to achieve this goal, the methods of collecting, analyzing and synthesizing information were employed. The outcome of work was understanding and characterizing of the format in which changes can occur within the framework of the new MaaS, which can contribute to illustrating a concept of passenger mobility in the foreseeable future.

El presente trabajo de investigación presenta la comparación de dos análisis químicos realizados por separado en dos fechas del mismo año, a las fracciones volátiles destiladas desde hojas de la especie Piper subscutatum, recolectadas en Numbani, Zamora Chinchipe, Ecuador. El primero de ellos, Cuantitativo, con la fracción volátil destilada mediante arrastre de vapor, analizado con un detector FID y publicado previamente bajo el tema Essential Oil and Major Non-Volatile Secondary Metabolites from the Leaves of Amazonian Piper subscutatum (Ramírez Robles, Andrade Castillo, Vidari, & Gilardoni, 2021) y el segundo, publicado aquí, Semi-cuantitativo, mediante micro-hidrodestilación y analizado con un detector MSD, en ambos se utilizó cromatografía de gases con columnas polares y apolares, lográndose constatar 45 compuestos comunes entre ambos estudios, los mayoritarios fueron sesquiterpenos hidrocarburos (55,65% y 41,68%), sesquiterpenos oxigenados (8,55% y 8,75%) monoterpenos hidrocarburos (8,25% y 28,72%), y minoritarios: monoterpenos oxigenados (1,25% y 3,96%) y otros (2,5% y 3,58%), también se determinó la desviación estándar para cada compuesto en ambos análisis y un perfil químico cualitativo-cuantitativo del aceite esencial. En ambos estudios el compuesto más abundante fue el sesquiterpeno (E)-cariofileno, seguido por β-chamigreno y E-nerolidol, que tienen usos farmacológicos, en el segundo y tercer lugar respectivamente para el primer estudio, mientras que en el segundo estudio fueron los monoterpenos: α-pineno, y β-pineno los que ocuparon esos lugares, desplazando a  β-chamigreno  y E-nerolidol del segundo al noveno lugar y de tercer al cuarto lugar respectivamente, al final se realizó una breve revisión de las actividades registradas para los terpenos mayoritarios más significativos los cuales podrían tener potenciales e interesantes aplicaciones farmacológicas y agroquímicas.
