Abstract
Background：Novel coronavirus disease（COVID-19）has become a worldwide pandemic and precise fatality data by age group are needed urgently. This study to delineate the clinical characteristics and outcome of COVID-19 patients aged ≥75 years and identify the risk factors of in-hospital death.Methods：A total of 141 consecutive patients aged ≥75 years who were admitted to the hospital between 12th and 19th February 2020. In-hospital death, clinical characteristics and laboratory findings on admission were obtained from medical records. The final follow-up observation was 31st March 2020.Results：The median age was 81 years (84 female, 59.6%). Thirty-eight (27%) patients were classified as severe or critical cases. 18 (12.8%) patients had died in hospital and the remaining 123 were discharged. Patients who died were more likely to present with fever (38.9% vs. 7.3%); low percutaneous oxygen saturation(SpO2) (55.6% vs. 7.3%); reduced lymphocytes (72.2% vs. 35.8%) and platelets (27.8% vs. 4.1%); and increased D-dimer (94.4% vs. 42.3%), creatinine (50.0% vs. 22.0%), lactic dehydrogenase (LDH) (77.8% vs. 30.1%), high sensitivity troponin I (hs-TnI) (72.2% vs. 14.6%), and N-terminal pro-brain natriuretic peptide (NT-proBNP) (72.2% vs. 6.5%; all P<0.05) than patients who recovered. Male sex (odds ratio [OR]=13.1, 95% confidence interval[CI] 1.1 to 160.1, P=0.044), body temperature >37.3°C (OR=80.5, 95% CI 4.6 to 1407.6, P=0.003), SpO2≤90% (OR=70.1, 95% CI 4.6 to 1060.4, P=0.002), and NT-proBNP>1800ng/L (OR=273.5, 95% CI 14.7 to 5104.8, P<0.0001) were independent risk factors of in-hospital death. Conclusions：In-hospital fatality among COVID-19 patients can be estimated by sex and on-admission measurements of body temperature, SpO2, and NT-proBNP.

Published: November 2020

Abstract
Background: The fracture of mandible remains one of the most facial fractures and its healing is a complex process, involving nerve and growth factors. Currently, nerve growth factor not only benefits maintenance of sympathetic neurite growth but also takes part in the intricate regulatory network to stimulate other growth factors such as bone morphogenic protein (BMP) and vascular endothelial growth factor (VEGF), which promote together essential osteogenesis and angiogenesis to physiological bone formation, growth and fracture healing. Therefore, it is necessary to analyze the combination of nerve growth factor (NGF), bone morphogenic protein-9 (BMP-9), and VEGF to accelerate the healing rate of mandible fracture.Methods: The models of mandible fracture with local nerve injury established in forty-eight rabbits were randomly divided into nerve growth factor group (NGF group), gelatin sponge group (GS group), blank group, and intact group with 12 rabbits in each group. The fracture healing was observed with visual and X-ray after the operation, then callus tissue in mandibular fracture area were collected for hematoxylin and eosin (HE) staining observation, and quantitative real-time PCR (qRT-PCR) was used to detect the expression of BMP-9 and VEGF in callus at different stages.Results: The combined results of macroscopic observation, X-ray examination, and histological section showed that a large number of osteoblasts and some vascular endothelial cells were found around the trabecular bone in the NGF group and the amount of callus formation and reconstruction was better than GS group at 2nd weeks after the operation. QRT-PCR result indicated that the expression levels of BMP-9 mRNA and VEGF mRNA in the four groups reached the highest value at 2nd week, and then decreased with time. At the same time, the content of BMP-9 and VEGF in callus tissue in the mandibular fracture area increased significantly in the NGF group than the GS group.Conclusion: The exogenous NGF could improve the expressions of BMP-9 and VEGF at the early stage of mandibular fracture to accelerate the healing of mandible fracture. This work will provide a new foundation and theoretical basis to make a clear mechanism of fracture healing, thereby promoting patients’ fracture healing and reducing their disability rate.

Published: November 2020

Background:
The eccentric load has a great influence on the bearing capacity, which can
easily lead to a decrease in bearing capacity or even the destruction of working conditions.

Objective:
The prospects for bearing eccentric load research are put forward, hoping to provide some help for the development and optimization of bearings.

Methods:
According to recently published patents and journal papers, the theoretical and experimental research on bearing eccentric load conditions are summarized, and research progress at home and abroad is discussed. This article summarizes the research status of bearing anti-eccentric load. Finally, the research direction of bearing eccentric load and the research direction of anti-eccentric load are prospected.

Results:
The article discusses eccentric load-bearing theory method, simulation method, detection method, experimental method and anti-eccentric load method.

Conclusion:
Aiming at the research hotspot of eccentric load, this paper collects and analyzes the literature
at home and abroad on theoretical analysis, experimental testing, anti-eccentric load and so on. After
research, scholars at home and abroad have made good progress in the direction of the eccentric
load, and put forward some methods and devices that have been applied in practical engineering. However,
the detection of eccentric load and the anti-eccentric load cannot be synchronized, and the robustness
of the design system is poor. Research on eccentric load at home and abroad is still in its infancy.

Published: November 2020

Background:
There are different types of pollutants in water hence they are
constantly in competition for active sites during the adsorption process. A key advantage
of competitive adsorption studies is that these inform regarding the adsorbent’s performance
in real water treatment applications.

Objective:
This study aims to investigate the competitive adsorption of Pb(II), Cu(II),
Fe(II) and Zn(II) using elephant grass (Pennisetum purpureum) biochar and hybrid biochar
from LDPE.

Method:
The produced biochar was characterised by Scanning Electron Microscopy
(SEM) and Fourier Transform Infrared Spectroscopy (FTIR). The adsorption parameters,
equilibrium isotherm modelling and parametric studies were conducted based on data
from the batch adsorption experiments.

Results:
For both adsorbents, the removal efficiency was >99% over the entire investigation
for dosage and contact time, suggesting that they are very efficient for removing multiple
heavy metals from aqueous media. It was observed that removal efficiency was optimal
at 2 g/l dosage and contact time was 20 minutes for both adsorbent types. The Elovich
isotherm and the pseudo-second order kinetic models were best-fit for the competitive
adsorption process.

Conclusion:
The study was able to successfully reveal that biomass biochar from elephant
grass and hybrid biochar from LDPE can be used as effective adsorbent material for
the removal of heavy metals from aqueous media. This study bears a positive implication
for environmental protection and solid waste management.

Published: November 2020

Background
In addition to the obvious physical medical impact of COVID-19, the disease poses evident threats to people’s mental health, psychological safety, and well-being. Provision of support for these challenges is complicated by the high number of people requiring support and the need to maintain physical distancing. Text4Hope, a daily supportive SMS text messaging program, was launched in Canada to mitigate the negative mental health impacts of the pandemic among Canadians.

Objective
This paper describes the changes in the stress, anxiety, and depression levels of subscribers to the Text4Hope program after 6 weeks of exposure to daily supportive SMS text messages.

Methods
We used self-administered, empirically supported web-based questionnaires to assess the demographic and clinical characteristics of Text4Hope subscribers. Perceived stress, anxiety, and depression were measured with the 10-Item Perceived Stress Scale (PSS-10), the Generalized Anxiety Disorder–7 (GAD-7) scale, and the Patient Health Questionnaire–9 (PHQ-9) scale at baseline and sixth week time points. Moderate or high perceived stress, likely generalized anxiety disorder, and likely major depressive disorder were assessed using cutoff scores of ≥14 for the PSS-10, ≥10 for the GAD-7, and ≥10 for the PHQ-9, respectively. At 6 weeks into the program, 766 participants had completed the questionnaires at both time points.

Results
At the 6-week time point, there were statistically significant reductions in mean scores on the PSS-10 and GAD-7 scales but not on the PHQ-9 scale. Effect sizes were small overall. There were statistically significant reductions in the prevalence rates of moderate or high stress and likely generalized anxiety disorder but not likely major depressive disorder for the group that completed both the baseline and 6-week assessments. The largest reductions in mean scores and prevalence rates were for anxiety (18.7% and 13.5%, respectively).

Conclusions
Text4Hope is a convenient, cost-effective, and accessible means of implementing a population-level psychological intervention. This service demonstrated significant reductions in anxiety and stress levels during the COVID-19 pandemic and could be used as a population-level mental health intervention during natural disasters and other emergencies.

Spheres of State Policy of the Russian Federation from the Perspective of Nation-Building: Correlation Priorities and Mechanisms
Authors: Bakhlova O. V. , Bakhlov I. V. 
Published: November 2020

Aims: to determine the General and special characteristics of official documents in the fields of state cultural policy, state youth policy and state national policy of the Russian Federation in terms of their interaction in terms of positions relevant to the perspective of nation-building.Methods: informal content analysis of documents, formal legal method, methods of comparative and system analysis, content analysis of the content of Internet resources, contextual analysis of political discourse.Results and discussion: the specifics of regulatory regulation of these areas are analyzed, the degree of their legislative institutionalization is revealed, and vulnerabilities that prevent greater correlation are shown. The content of the official websites of Federal government bodies and their structural divisions responsible for the formation and implementation of state cultural, youth and national policies and Advisory bodies under them is studied, taking into account the coverage of planned and ongoing events and initiatives. The provisions that emphasize the issues of present and future States in certain spheres that are fundamental for official and theoretical discourse in the context of nation-building trends are outlined.Conclusion: the existing documents and mechanisms provided for by them ensure a fairly high degree of integration of various spheres of state policy of the Russian Federation. At the same time, they need to achieve a better balance of the main goals, tasks, and implementation mechanisms. Some forward-looking estimates for these areas in the medium term are justified, allowing for the probability of individual adjustments, including in the legislative sphere. At the same time, we recommend measures to improve management practices based on transformed paradigm approaches, primarily to the sphere of culture. The author argues for linking the proposed amendments within the framework of the constitutional reform with the guidelines of nation-building and priorities fixed in the spheres of state policy.
K.P. Pobedonostsev as Philosopher-Personalist
Authors: Darenskiy Vitaliy Yu. 
Published: November 2020

The article shows that K.P. Pobedonostsev belongs to the original Russian tradition of philosophical personalism, based not on neo-leibnizianism, but on the disclosure of the Orthodox experience of understanding man as the image and likeness of God. His philosophy agrees with the Russian paradigm of creating “new beginnings of philosophy” (I. Kireevsky), which is based on the principle of “integral mind”. Pobedonostsev’s concept of culture and history has personalistic character, considering any social and historical phenomena in terms of their personal content; and personal content - as the embodiment of the highest religious ideal of man. According to K.P. Pobedonostsev, the knowledge of God is based on the natural abilities of a person and always has personal character. The destruction of Christian moral consciousness, according to K.P. Pobedonostsev, leads to the degradation of man and society in the form of total public life depersonalization – the substitution of personal relations with dead institutions.
The Philosophic Discovery of Name and Icon: Chronological Parallels and Ideological Genesis
Authors: Mahler Elena S. 
Published: November 2020

The article describes the discovery of “name” and “icon” as two new philosophic categories in Russian philosophy of the Silver Age and the formation of two new directions in Russian thought – “philosophy of name” and “philosophy of icon” – in their close interconnection. It is noted that those directions of thought developed in parallel to each other, which can be found on the pages of the similar or even the same works of the same group of philosophers – E. Trubetskoy, P. Florensky, A. Losev, S. Bulgakov. Similar features of the ideological genesis and problems of those areas of thought are considered in detail, among which are: criticism of secularism and church modernism, opposition to the “new religious consciousness” and the choice of historical Christianity, interest in real religious tradition and practice, and philosophical resort to Patristics, including their predecessor, – Father John of Kronstadt. In general, the author concludes that those trends in Russian thought are deeply interconnected, from their ideological genesis to philosophical problems, which are manifested in the similar understanding of the categories of “name” and “icon” at different levels – ontological, epistemological, communicative, and personalistic.
“Red Priests” as Phenomenon of the Epoch of the Revolution and the Civil War (The Destiny of Iona Brikhnichev and Mikhail Galkin)
Authors: Rogozny Pavel G. 
Published: November 2020

The phenomenon of priests taking off dignity after the revolution was a common one. But Brikhnichev and Galkin were not only former priests, but also high-ranking leaders of the “Union of Atheists”. Both of them were active supporters of the new power, and members of the Bolshevik party. Brikhnichev was a writer and poet before the revolution. He was defrocked for his Christian radicalism. Galkin was a priest of the Metropolitan parish before the revolution. He himself offered his services to the Bolsheviks in carrying out the separation of the Church and State and published his proposals in “Pravda” newspaper. Then he took off his orders and became an atheist. The careers of Brikhnichev and Galkin ended when the new government no longer needed the services of former priests-propagandists. Very often the priests, both former or active, were called ”red priests“.
Problems of Legal Regulation of Palliative Medical Care in the Russian Federation
Subjects
Authors: Trutaeva Anna 
Published: November 2020

Introduction. The problem of ensuring equal scope of the right to palliative medical care of citizens living
on the territory of various subjects of the Russian Federation is raised. The article describes the current legal
regulation of palliative care in the Russian Federation and the existing problems of providing it. Purpose. The
author aims to determine the place of legal regulation in the mechanism of ensuring the right to palliative
medical care and ways to increase the degree of guarantee of this right. Methodology. Methods of analysis
and synthesis, formal-logical and comparative-legal methods are used. Results. A brief overview of the current
legal regulation at the Federal level and in the subjects of the Russian Federation is given, and the different
scope of the right to palliative medical care of citizens living on the territory of different subjects of the Russian
Federation is recorded. The article highlights the consequences of different approaches to the legal regulation of
the issues under consideration, and suggests changes to them. Population by sex and age, the structure of its
incidence and the degree of disability in subjects of the Russian Federation are not the same, and the bodies of
state power of subjects of this level have the ability to define the needs of the population in the form of medical
care that is consistent with the goal inherent in the activities of the bodies of state power of subjects of the
Russian Federation in the field of social security, namely with regard to the influence of the specific features on
the life of citizens and securing a reasonable differentiation of social security. Conclusion. It is concluded that
it is necessary to fix the guarantee of palliative medical care in the normative legal acts of the subjects of the
Russian Federation regulating the issues of public health protection, regardless of the territory of living, gender,
age, diagnosis and stage of treatment.
Los destinos turísticos inteligentes: el pilar de la recuperación turística
Authors: García Moreno Beatriz , Fernández Alcantud Andrés 
Published: November 2020

El sector turístico mundial está viviendo la peor situación de su historia, motivada por la crisis sanitaria provocada por el COVID-19. La problemática es sobre todo más acuciante en países que, como España, contaban con un importante sector turístico que daba empleo directo a cerca de 3 millones de personas, 13% del empleo total, y supone cerca de un 12% de su PIB.
Para poder recuperarse España está apostando por el modelo de Destinos Turísticos Inteligentes (DTI) y la Red DTI que engloba a estos destinos. La metodología DTI se basa en 5 ejes de actuación que son la Gobernanza, la Innovación, la Tecnología, la Sostenibilidad y la Accesibilidad. Es resaltable, además, la importancia del conocimiento y el uso de Sistemas de Inteligencia Turística que permiten una correcta toma de decisiones.

Abstract
Increasing concentration of antibiotics in environment and their subinhibitory concentrations in wastewater may result in increased antibiotic resistance of present bacteria. Therefore, this study was aimed to analyze the efficiency of coagulase-positive staphylococci and Staphylococcus aureus inhibition in wastewater by electrochemical methods and addition of ferrates. Advanced electrochemical oxidation by boron doped diamond electrodes in anode; cathode and anode-cathode connection were used for wastewater disinfection. Results showed that the most effective connection was the anodic one, as complete inhibition of coagulase-positive staphylococci as well as of S. aureus was observed after 40 min. Energy consumption was 3.69 kWh/m3 for effluent wastewater disinfection. The second studied method of wastewater disinfection was the application of powdered ferrates. Addition of 100 mg of ferrates resulted in the inhibition of 84—96 % of coagulase-positive staphylococci and 97—99 % of S. aureus in influent water, while the inhibition of coagulase-positive staphylococci and S. aureus was 61—83 % and 83—86 %, respectively, in effluent wastewater.
