Published: September 2020

Abstract
Laser direct joining of carbon fiber reinforced thermoplastic (CFRTP) composite plate and titanium alloy plate with a thickness of 2 mm was performed with swing laser. Numerous air bubble of submillimeter size were observed inside the fusion zone of CFRTP and titanium alloy at the cross section of the joints. The air bubble characteristics were analyzed based on the morphology and size, while the formation mechanism of air bubble was further elucidated according to the nucleation mode, nucleation site and nucleation position. The results demonstrated that the nucleation modes of air bubble are substantially divided into homogeneous nucleation and heterogeneous nucleation, which is related to the nucleation sites. The nucleation mode presents a crucial factor influencing the position and morphology of air bubble. In addition, the air bubble characteristics are also determined by the clamp pressure and resin flow. The final morphology of air bubble is primarily represented by four typical types.

Abstract
Conventional biorefinery processes are complex, engineered and energy-intensive, where biomass fractionation, a key functional step for the production of biomass-derived chemical substances, demands industrial organic solvents and harsh, environmentally harmful reaction conditions. There is a timely, clear and unmet economic need for a systematic, robust and affordable conversion method technology to become greener, sustainable and cost-effective. In this perspective, deep eutectic solvents (DESs) have been envisaged as the most advanced novel polar liquids that are entirely made of natural, molecular compounds that are capable of an association via hydrogen bonding interactions. DES has quickly emerged in various application functions thanks to a formulations’ simple preparation. These molecules themselves are biobased, renewable, biodegradable and eco-friendly. The present experimental review is providing the state of the art topical overview of trends regarding the employment of DESs in investigated biorefinery-related techniques. This review covers DESs for lignocellulosic component isolation, applications as (co)catalysts and their functionality range in biocatalysis. Furthermore, a special section of the DESs recyclability is included. For DESs to unlock numerous new (reactive) possibilities in future biorefineries, the critical estimation of its complexity in the reaction, separation, or fractionation medium should be addressed more in future studies.

Published: September 2020

Context
Obesity and cardiometabolic diseases are associated with higher long-term glucocorticoid levels, measured as scalp hair cortisol (HairF) and cortisone (HairE). Cardiometabolic diseases have also been associated with copeptin, a stable surrogate marker for the arginine-vasopressin (AVP) system. Since AVP is, together with corticotropin-releasing hormone (CRH) an important regulator of the hypothalamic-pituitary adrenal axis (HPA axis), we hypothesize that AVP contributes to chronic hypercortisolism in obesity.

Objective
To investigate whether copeptin levels are associated with Higher HairF and HairE levels in obesity.

Design
A cross-sectional study in 51 adults with obesity (BMI ≥30 kg/m2).

Methods
Associations and interactions between copeptin, HairF, HairE, and cardiometabolic parameters were cross-sectionally analyzed.

Results
Copeptin was strongly associated with BMI and waist circumference (WC) (rho = 0.364 and 0.530, P = 0.008 and <0.001, respectively), also after correction for confounders. There were no associations between copeptin and HairF or HairE on a continuous or dichotomized scale, despite correction for confounders.

Conclusion
In patients with obesity, AVP seems not a major contributor to the frequently observed high cortisol levels. Other factors which stimulate the HPA axis or affect cortisol synthesis or breakdown may be more important than the influence of AVP on long-term glucocorticoid levels in obesity.

USE OF DIGITAL TECHNOLOGIES IN VOTING AT THE GENERAL MEETING OF PARTICIPANTS (SHAREHOLDERS’) BUSINESS ENTITY
Authors: Elnikova E. V. 
Published: September 2020

The article deals with issues related to the exercise of the right to participate in the General meeting of participants (shareholders) of economic companies through the use of digital technologies. The Russian corporate legislation provides for the possibility of voting at the General meeting using electronic means. The conclusion is made that it is necessary to expand the dispositive regulation, which provides corporations with more opportunities to determine the directions necessary for them to implement new technologies. The advantages of using electronic voting forms in joint-stock companies with a large number of shareholders are considered. The risks associated with the use of digital technologies when voting at the General meeting are highlighted. Attention is drawn to the need to develop ways to ensure the evidence base for the Commission member of the Corporation’s actions by voting in electronic form. It was suggested that the introduction of digital technologies in the voting procedures at the General meeting of participants (shareholders) leads to a gradual leveling of the differences between decision-making in face-to-face and absentee voting.

Published: September 2020

Objective. To describe in details the prevention of scoliotic spinal deformity in children with mild neuro-orthopedic pathology.
Materials and methods. The health status of 125 children aged 3 to 15 years was studied. To investigate in details the neuro-orthopedic pathology and estimate the efficiency of treatment, the method of computed optic topography and electroneuromyography was used.
Results. Clinical and functional features in children with mild neuro-orthopedic disorders were characterized by the combination of vegetative, topographic and electromyographic changes. Scoliosis and spinal deformity progressed in children, who were not treated. Computer-topographic method of diagnosis determines the degree of severity of spinal state. Electroneuromyographic study is the method that permits to assess and predict the muscular dysfunction degree. All the children had conservative complex treatment at ambulatory-polyclinic rehabilitation institutions. The total efficiency of treatment was 95 %.
Conclusions. 1. Mild neuro-orthopedic pathology is formed and progresses against the background of neuro-muscular and vegetative disorders while a child is growing and developing. 2. Computed optic topography is a reliable early diagnostic and prognostic criterion for estimation of scoliosis in the therapeutic program. 3. Purposeful conservative treatment and follow-up of children and adolescents prevent the progression of neuro-orthopedic pathology.

Published: September 2020

O crescimento mal planejado das grandes cidades acarreta o aparecimento das chamadas ilhas de calor urbano, que consequentemente geram desconforto nos cidadãos. Em um contexto universitário, o desconforto térmico pode prejudicar a concentração e desempenho de alunos, professores e funcionários. Assim simulou-se o microclima da Universidade de Cuiabá, campus Barão, com o objetivo de analisar as partes críticas desconfortáveis do campus e sugerir estratégias que possam melhorar o conforto térmico local. Para a simulação utilizou-se o software ENVI-met, que espacializa as variáveis temperatura do ar e umidade relativa do ar, sendo simulados os horários de 08, 14 e 20 horas no período chuvoso e seco, conforme a sazonalidade climática local. Encontrou-se como zonas críticas a entrada do Campus, Bloco A, a área de convivência nos intervalos dos alunos e o estacionamento, atingindo temperaturas máximas de 34 ºC. Outra questão que causa preocupação é a baixa umidade relativa do ar no período seco, em que as 14 horas chegou a mínima 23%. Conclui-se que a intensificação de áreas verdes no campus, como gramados e arborização, a substituição de pavimentos, substituindo parte da área asfáltica por pavimentos de calor específico menor, e a utilização de telhado verde, podem contribuir para a melhoria do conforto térmico do campus.

Abstract
The poorly planned growth of large cities leads to the appearance of the so-called urban heat islands, which consequently generate discomfort for citizens. In a university context, thermal discomfort can impair the concentration and performance of students, teachers and staff. Thus, the microclimate of University of Cuiabá, Barão campus was simulated, with the objective of analyzing the uncomfortable critical parts of the campus and suggesting strategies that can improve the local thermal comfort. For the simulation, the ENVI-met software was used, which spatializes the variables air temperature and relative air humidity, simulating the times of 08, 14 and 20 hours in the rainy and dry period, according to the local climatic seasonality. Critical areas were the entrance to Campus, Block A, the living area in the students’ break time and the parking, reaching maximum temperatures of 34ºC. Another issue that causes concern is the low relative air humidity in the dry period, when the 14 hours reached a minimum 23%. It is concluded that the green areas intensification at the campus, such as lawns and afforestation, the replacement of pavements, replacing part of the asphalt area with pavements with lower specific heat, and the use of a green roof, can contribute to the improvement of the campus thermal comfort.

Published: September 2020

Background: Infectious mononucleosis (IM), characterized by fever, lymphadenopathy and pharyngitis, is a common infectious disease caused by Epstein-Barr virus (EBV). In this study, we performed a retrospective analysis of the clinical findings, laboratory data and management of children with IM due to EBV to find out the predictors of hospitalizations. Methods:We retrospectively reviewed the medical records of patients under the age of 18 years who were diagnosed with IM between October 31, 2017 and October 31, 2018 at Muğla Sıtkı Koçman University Medical Faculty Hospital. The study population was categorized into three groups according to the age; the 0-4 years, 5-10 years, and above 10 years. Complaints, physical examination findings, laboratory data, complications and treatment strategies of the patients were compared in these groups. Factors associated with hospitalizations and predictors of hospitalization were also investigated.Results: This study included 158 patients. The mean age of the patients was 88.9 ± 53.5 months and 93 (58.9%) were male. The most common complaint was fever (57.6%), and the most common physical examination finding was hepatomegaly (73.4%). No significant difference was found between the age groups in most of the clinical and laboratory findings. The antibiotic treatment was administered in 44% of the patients and 34.8% of the patients were required hospitalization. Patients who needed hospitalization were more symptomatic, had more physical examination findings and had higher acute phase reactants. For variables were found to be significant predictors of hospitalization: presence of fever, palatal petechiae, or exudative tonsillitis and higher levels of C-reactive protein at presentation.Conclusions: More than one third of the children with IM required hospitalization. Presence of fever, palatal petechiae, or exudative tonsillitis and higher levels of C-reactive protein at presentation were ssociated with higher rates of hospitalizations.

Abstract
Background: The novel coronavirus disease 2019 (COVID-19) has emerged as a major global public health challenge. This study aimed to investigate how people perceived the COVID-19 outbreak using the components of the Extended Parallel Process Model (EPPM) and to find out how this might contribute to possible behavioral responses to the prevention and control of the disease.Methods: This cross-sectional study was conducted online in Iran in March and April 2020. The Data were collected using an electronic questionnaire via Porsline. Participants were recruited using online applications and posts on a number of platforms such as Telegram, WhatsApp, and Instagram asking people to take part in the study. To collect data a self-designed questionnaire based on the EPPM was used in order to measure the risk perception (efficacy, defensive responses, perceived treat) related to the COVID-19. Descriptive statics, chi-square, t-test and analysis of variance (ANOVA), were used to explore the data.Results: A total of 3,727 individuals with a mean age (SD) of 37.0 (11.1) years participated in the study. The results revealed significant progressive increases in efficacy, defensive responses and perceived treat particularly among those aged 60 and over. Women had significantly higher scores than men on some aspects such as self-efficacy, reactance, and avoidance but men had higher perceived susceptibility scores for COVID-19 than women. Overall 56.4% of participants were engaged in danger control (preventive behavior) while the remaining 43.6% were engaged in fear control (non-preventive behavior) process.Conclusion: More than half of all participants motivated by danger control. This indicated that more than half of participants had high perceived efficacy (i.e., self-efficacy and response efficacy). Self-efficacy scores were significantly higher among participants who were older, female, single, lived in rural areas, and had good economic status. The results suggest that socioeconomic and demographic factors are the main determinants of risk perceptions for controlling the COVID-19 pandemic.

Abstract
Traffic congestion is one of the problems for cities around the world due to the rapid increasing of vehicles in urbanization. Traffic flow prediction is of a great importance for Intelligent Transport System (ITS) which helps to optimize the traffic regulation of a transportation in the city. Nowadays, several researches have been studied so far on traffic flow prediction, accurate prediction has not yet been exploited by most of existing studies due to the impact of inability to effectively deal with spatial temporal features of the times series data. Traffic information in transportation system will also be affected by different factors. In this research we intended to study various models for Traffic flow prediction on the basis machine learning and deep learning approaches. Factors affecting the performance of traffic flow prediction intensity are studied as well. Benchmark performance evaluation metrics are also reviewed. Generally, this manuscript covers relevant methods and approaches, review the state-of-art works with respect to different traffic flow prediction technique help researchers in exploring future directions so as to realize robust traffic flow prediction.
