INFLUENCE OF CHANNEL GEOMETRY, PRESSURE, TEMPERATURE, OSCILLATIONS AND ADSORPTION ON OBLITERATION OF SLIT SEALS OF ELECTRIC POWER SYSTEMS
Authors: KRESTIN Evgeny A. , SEREBRYAKOV Grigoriy V.
Published: March 2021

The infl uence of the geometric dimensions and confi guration of slot contactless seals on the obliteration of the gaps of plunger pairs at the design and calculation stage of drive systems of electric power systems units is considered. The combined eff ect of working fl uid contamination and the adsorption eff ect on the overgrowth of the living section of the channel was revealed. The fl ow rate during sample shedding was reduced simultaneously as a result of the channel overgrowing with contamination particles and adsorption, i.e. the formation of boundary fi lms on the channel walls. Leaks through the gap at concentric and eccentric position of the plunger in the sleeve are determined. The minimum gap is found, at which the obliteration process is stabilized and loose mud formations are washed away by the fl ow of the working fl uid. The infl uence of the pressure drop at the ends of the slot gap on the channel obliteration process was revealed. With an increase in the pressure drop, the process of stratifi cation of adsorbed layers of polar molecules accelerates, resulting in an increase in the number of contamination particles trapped in the gap per unit of time. With an increase in the temperature of the working fl uid, the process of channel obliteration accelerates, which is confi rmed by experiments. With an oscillating plunger, the fl ow through the annular gap is less than with a stationary one. This is due to the fact that the oscillating plunger occupies a position in the sleeve close to the concentric one, at which leaks are minimal. A stable fl ow rate is obtained when the working fl uid fl ows through the gaps of the plunger pairs performing reciprocating oscillating movements.
INFLUENCE OF THE BIOMASS CARRIER TYPE ON THE OXYGEN TRANSFER RATE OF THE MODIFIED SUBMERSIBLE ROTATING BIOFILTER
Authors: SAIED Maram Ali , SERPOKRYLOV Nikolay S. , NELIDIN Vladimir V.
Published: March 2021

The modifi ed submersible rotating biofi lter MSRB was developed and patented to improve the effi ciency and quality of treated wastewater from small sett lements in Syria by increasing the mass transfer rate and oxygen transfer rate of the drum-type rotating biofi lter without the need for additional aeration elements. The result of comparing the eff ect of two types of biomass carrier on the oxygen transfer rate OTR shows that the highest value of the OTR when using the fi rst biomass carrier (1) was 409 g/m3·h with a drum fi lling percentage of 60%, a rotation speed of 15 rpm and an immersion depth of 35% While the maximum value when using the second biomass carrier (2) was 518.95 g/m3·h with a drum fi lling percentage of 90%, a rotation speed of 15 rpm and an immersion depth of 15%. It can also be concluded that a change in the shape of the biomass carrier, as well as its density, signifi cantly aff ects the OTR of the biofi lter. In addition, changing the shape of the biomass carrier requires changing other technological parameters, such as the fi lling percentage of the drum, the depth of immersion and the rotation speed.
Las columnas de la lengua sobre comunicación política del Marqués de Tamarón y de Álex Grijelmo: la “lengua” de los políticos en cuestión
Authors: Sánchez Manzanares Carmen
Published: March 2021

El objetivo de este artículo es indagar en el análisis de la comunicación política que se realiza en las columnas sobre la lengua publicadas en diarios españoles después del período político conocido como la transición. Para ello, hemos seleccionado a dos columnistas, el Marqués de Tamarón y Álex Grijelmo, que escriben, respectivamente, en los años ochenta del siglo XX y en las primeras décadas del siglo XXI. Hemos examinado el tratamiento que realizan de los recursos y estrategias señalados en los estudios críticos del discurso y la pragmática lingüística para la caracterización de los usos políticos del lenguaje. Los resultados de nuestro análisis muestran que el Marqués de Tamarón opta por una caracterización sociológica del habla “incorrecta” de los políticos, mientras que el interés de Grijelmo es la legitimidad del discurso de los actores políticos. Se concluye que la discusión lingüística que se presenta en sus columnas no está motivada únicamente por las finalidades propias del género metalingüístico al que se adscriben. El propósito es interpretar, en el caso del Marqués de Tamarón, los cambios sociales que inducen la jerga usada por los políticos, y, en el de Grijelmo, la manipulación de los acontecimientos políticos referidos en el discurso.

Acute vision loss in a patient with chronic esophageal stenosis
Authors: Paul Joshua , Zhang Yi , Sun Justin
Published: March 2021

Abstract:

Purpose: To describe a unique cause of Valsalva Retinopathy (VR) with an alternative surgical approach to chronic non-clearing pre-foveal hemorrhage.

Method: Case presentation.

Results: A 45-year-old African American female presented with acute vision loss from 20/20 to count fingers (CF) in her right eye. Ophthalmoscopy and ocular coherence tomography (OCT) showed old yellow-red pre-retinal opacityscuring the fovea. After 1 month of conservative management with no improvement, Pars Plana Vitrectomy (PPV) with posterior hyaloid membrane removal without ILM peeling was performed with the patient’s best-corrected visual acuity (BCVA) dramatically improved to 20/25.

Discussion: We raise the question regarding the role of ILM peeling in treating premacular hemorrhage. Even without ILM peeling, our patient’s hemorrhage resolved after the procedure. This suggests that PPV combined with posterior hyaloid removal is a safer and effective alternative to surgical treatment in patients with certain clinical conditions. In addition, we provide clear evidence to support the location of the hemorrhage in VR as both sub-hyaloid and sub-ILM.
Milorad Dodik’s Public Attitudes and Perceptions Toward the ICTY
Authors: Hasić Jasmin , Yesilyurt Zejna
Published: March 2021

The International Criminal Tribunal for the former Yugoslavia (ICTY) was‎ formally closed on 21 December 2017. During the quarter century of its existence, ‎ICTY’s rulings had a significant impact on public discourses and narratives‎ about the Bosnian war. Different opinions among the citizens of Bosnia‎ and Herzegovina (BiH) about ICTY’s role and its verdicts have emerged over ‎time, especially among the leaders of the dominant ethno-political parties representing ‎the three ethno-constituent groups – Bosniaks, Croats, and Serbs.‎ Milorad Dodik, current member of the BiH Presidency, a former President of ‎Republika Srpska (RS) entity, and the leader of one of the most prominent political‎ parties in RS, was particularly vocal and critical about the work of the ‎ICTY. This paper closely examines Dodik’s public views and opinions toward ‎the ICTY. We use content- and operational code analysis to analyze key features‎ of his perceptions toward the ICTY’s work while serving as the President ‎of RS for two consecutive terms.‎
Transsexualism Ethiology and Medical Management: Between Scientific Evidence and Personal Experiences
Authors: Vetri Mario , Cataldi Alessia , Naselli Adriano , Vetri Annalisa
Published: March 2021

Gender Identity Dysphoria (GID) is a condition characterized by a strong and persistent identification with the opposite sex. These people consider themselves victims of a sort of biological accident: "a soul in a wrong body". There are numerous theories on the origin of transsexualism: genetic, hormonal and psychological causes have been hypothesized, but those currently most accredited are the neuroanatomical ones. The cornerstones of hormone conversion therapy (Gender Affirming Hormone Therapy, GAHT) are feminizing hormones for transgender women (MtFs) and virilizing for transgender males (FtMs). GID can be present among adolescents and older people. For adolescents is now accepted reversible treatment of puberty withdrawal with hormones that stops the progression of pubertal development in the biological direction not accepted; for elderly people is suggested GAHT in reduced doses. Physicians should consider and discuss with people with GID about fertility preservation, general and cancer risks. We present also data of 127 transsexual patients enrolled at the Garibaldi-Nesima Andrology Clinic in Catania (Italy) from 2003 to 2020. To optimize the conversion treatment with sex hormones, transsexuals require long-term follow-up. GAHT must be performed by a doctor who is familiar with these problems. Therefore, the “do-it-yourself” trend and the lack of medical and laboratory checks over time should be absolutely discouraged. Before proceeding with the surgical sex reassignment, it is recommended to refer to an endocrinologist and psychologist or psychiatrist for a period of 2-3 years. The transition surgical conclusion process must be practiced by a quality surgical team.

The Constraint of the Eco-Friendly Rooftop PV System Implementation Based on the Techno-Economic and Regulatory Impact Analysis: Case Study of the Ontowiryo Mosque in Purworejo, Central Java, Indonesia
Authors: Suparwoko Woko - , Qamar Fadhil Ahmad
Published: March 2021

PV system is an eco-friendly option to meet the need for energy due to its lower carbon footprint when compared to the fossil-fueled power plants. In this research, we performed techno-economic and regulatory impact analysis on a rooftop PV system on a mosque in Purworejo, Indonesia under a net metering mechanism. The use of PV system on the mosque rooftop can reduce its entire carbon emission from its annual energy usage, which equals to 4 tonnes of carbon dioxide equivalent. However, the economic feasibility of the PV systems, measured by the NPV of the electricity bill saving, shows negative values for all PV system configuration, defined by the type and number of panels. This low financial attractiveness is resulted from several unsupportive regulations: the subsidized electricity tariff, the minimum grid electricity usage limit and the less rewarding net metering scheme. The abolishment of minimum usage limit incurs the greatest increase of NPV to the PV system that is designed to entirely supply the load demand. While the implementation of higher electricity tariff incurs the highest increase of NPV for the PV systems with partial supply scenario. This study shows that at the current electricity tariff, costs of components, and the implemented regulations around the adoption of PV system, it is financially unfeasible to install a PV system on the mosque rooftop.
Carbon-nanotube yarns induce axonal regeneration in peripheral nerve defect

Published: March 2021

Carbon Nanotubes (CNTs) are cylindrical nanostructures, and have unique combination of properties including flexibility, electrical conductivity, and biocompatibility. We focused on CNTs fabricated with the carbon nanotube yarns (cYarn®) as a possible substrate that could promote peripheral nerve regeneration with these properties. We bridged a 15mm rat sciatic nerve defect with five different density of cYarn®. Eight weeks after the surgery, the density of regenerated axons crossing the CNTs, electromyographical findings, and muscle weight ratio of the lower leg showed recovery of the motor function by the interfacing with cYarn®. Our results indicated that a 2% CNT density tended to be most effective for nerve regeneration as measured by both histological axonal regeneration and motor function. We confirmed that CNT yarn, used as a scaffold bridging nerve gaps, promotes peripheral nerve regeneration. Our results support the future clinical application of CNTs for bridging nerve gaps as an off-the-shelf material.
Highly effective Fe-N-C electrocatalysts toward oxygen reduction reaction originated from 2,6-diaminopyridine
Authors: Yang Weixiang , Tang Shuihua , Huang Qiankuan , Zhang Qian , Tang Zhen , Yang Shuang
Published: March 2021

Fe-N-C electrocatalysts have been intensively studied due to their extraordinary catalytic activity toward oxygen reduction reaction (ORR). Here we prepare a Fe-N-C electrocatalyst through cost-effective and nontoxic precursors of 2,6-diaminopyridine (DAP) and FeCl3, where iron ions react with DAP to formed Fe-Nx species first, followed by polymerization and pyrolysis. X-ray diffraction patterns display no obvious Fe2O3 peaks observed in the catalyst as the nominal content of iron addition is less than 10 wt%. X-ray photoelectron spectroscopy spectra indicate that the catalyst has rich pyridinic nitrogen, graphitic nitrogen and Fe-Nx species, which are considered as active sites for ORR. Therefore the catalyst demonstrates an excellent catalytic activity with an onset potential of about 0.96 V, half-wave potential of about 0.84 V, and a limiting current density of 5.8 mA cm-2, better than commercial Pt/C catalyst in an alkaline medium. Furthermore its stability is also much more excellent than that of Pt/C. This work provides a strategy to synthesize universal M-N-C catalysts.
Numerical Simulation of Convex Shape Beam Spot on Stress Field of Plasma-sprayed MCrAlY Coating During Laser Cladding Process
Authors: Zhang Peipei , Chu Jiaqing , Qu Guang , Wang Dongsheng
Published: March 2021

In order to reduce the thermal stress at clad layer and further reduce the crack generation in the laser cladding process, a method of controlling the cracks at clad layer by changing the laser energy density was proposed. The comparative thermal-mechanical coupling finite element analysis was conducted for the uniform rectangular spot and convex shape beam spot cladding processes on plasma-sprayed MCrAlY coating through the numerical simulation method based on the ANSYS software. The results show that the rapid heating and cooling characteristics, which are typical in laser processing, are manifested in the cladding process using the uniform rectangular spot, and the convex shape spot can exert the preheating and slow cooling effects to a certain extent, so as to reduce the temperature gradient of the cladding zone and non-cladding zone. In addition, on the precondition of equivalent cladding effect, the thermal stress at the clad layer is also low, so the cracking tendency of the clad layer can be effectively mitigated. Relative to the laser beam shaped diffractive optical element special for design and manufacturing, superposing two uniform rectangular spots with different sizes and energy densities is a simpler and more effective method of acquiring the convex shape spot.
The Value of Autopsy in Preterm Infants At A Swedish Tertiary Neonatal Intensive Care Unit 2002-2018

Published: March 2021

Reliable data on causes of death (COD) in preterm infants is needed to assess perinatal care and current clinical guidelines. In this retrospective observational analysis of all deceased preterm infants born <37 weeks’ gestational age (n=278; 2012-2018) at a Swedish tertiary neonatal intensive care unit, we compared preliminary COD from Medical Death Certificates with autopsy defined COD (2002-2018), and assessed changes in COD between two periods (Period 1: 2002-2009 vs Period 2: 2011-2018). Autopsy was performed in 73% of all cases and was more than twice as high compared to national rates of infant autopsies in Sweden (33%). Autopsy defined COD differed from preliminary COD in 34.9% of the cases. Necrotizing enterocolitis (NEC) as COD increased between Period 1 and 2 (5% vs 26%), while intraventricular hemorrhage decreased (13% vs 6%). The autopsy rate did not change between the two study periods (75% vs 71%). We conclude that autopsy changed the preliminary COD in a third of cases, while the incidence of NEC as COD increased markedly during the study period. Since there is a high risk to determine COD incorrectly based solely on clinical findings in preterm infants, autopsy remains a valuable method to obtain reliable COD.

Published: March 2021

Porodaedalea pini is a medicinally important mushroom with antioxidant, cytotoxic, immunostimulating, antitumor, antiviral and immunomodulating activities. Therefore, in this study, P. pini methanol extract and isolated compounds from the methanol extract were tested for cytotoxic activities against DLD-1 (colorectal cancer) and CCD-18Co (human colon fibroblast cell line) by using Alamar Blue assay. Cytotoxic activity on DLD-1 was decreased in the order of P. pini methanol extract> 4-(3,4-dihydroxyphenyl)but-3-en-2-one (3)> pinoresinol (2)> ergosta-7,24(28)-dien-3β-ol (1). P. pini methanol extract was determined to have the best cytotoxic activity with the lowest IC50 value on DLD-1 (IC50: 25.33±0.29 µg/mL) and the highest IC50 value on CCD-18Co (434.30±1.45 µg/mL). Within the scope of the findings, it is thought that P. pini mushroom can be used as a new and natural agent in the treatment of colorectal cancer.
The Impact of Funding on Quality of Early Childhood Education Service Provision in Zambia from 2015-2018
Authors: Simasiku Tashar
Published: March 2021

High-quality Early Childhood and Education (ECE) is critical to positive child development and generates high economic returns. On the contrary, Access to quality ECE in Zambia remains low particularly for the vulnerable. The situations are compounded by inadequate funding to the ECE subsector. This study evaluated the effect of funding on the quality of ECE in Zambia for the period 2015 to 2018. It assessed the effect of funding on the provision of ECE services by analysing the funding patterns to the Ministry of General Education through to Directorate of Early Childhood Education (DECE), Provincial Education Office (PEO), District Education Board Office (DEBO) and finally the 10 identified schools /ECE centres. To assess effect on quality, the study analysed the effect of funding on the eight identified early learning quality elements as espoused by the Ministry of General Education. These are, Infrastructure, Water and sanitation, Playgrounds, Furniture, Equipment and materials, Staffing, Support Staff and Enrolment. The methodology employed in this study included desk review of the funding reports at the identified fund management levels as well as Key Informant Interviews (KII) at each identified level. The results from the desk review and KII indicated that, funding to ECE for the period 2015 to 2018 was inadequate. At school level, much of the funding went toward equipment and materials while Water and Sanitation Infrastructure, Playgrounds, Furniture Equipment and materials were inadequately funded. This negatively affected the quality of ECE services provided in Zambia between 2015 to 2018.

Published: March 2021

The study is based on Open Defecation Free Zone and Their Practice in Jorayal Gaunpalika -4, Doti District. The main objective of the study is to analyze the practice of open defecation free zone. Out of 310 total households, only 150 households were selected for the study. The cluster sampling method was applied to collect necessary information. The study area was divided into 6 clusters and from each cluster 25 households were selected randomly. According to the study, hand wash practice is very high that is 85.3 percent wash their hands with soap and water and 14.7 percent use soil and water. The high majority of the respondents (88.7 percent) said that they maintained the garden and the toilet, 7.3 percent said that they kept the courtyard of the house plain. Most of the respondents (82.7 percent) cleaned the toilet every day. Most of the respondents (70.7) expressed that they defecated in the field, and 28.7 percent respondents said that they defecated along the riverside and remaining others used the road. In this study, the researcher gives suggestions to the concerned department and to possible future researchers. The government and non-government sectors should support such open defecation free zone area ensuring adequate environmental sanitation. The municipality should be made aware of the importance of a good environmental hygiene. Furthermore, such studies should be conducted at the national level.

Las librerías universitarias como generadoras de lectores
Authors: Torres Vargas Georgina Araceli
Published: March 2021

La producción de las editoriales universitarias deriva de las actividades de investigación, docencia y difusión que se llevan a cabo en la universidad, lo cual resulta en una oferta de obras muy especializada y, por lo mismo, cuenta con pocos lectores potenciales, casi todos investigadores, profesores y alumnos de la propia universidad. El bajo consumo de la producción editorial universitaria también obedece a una limitada distribución y venta mediante canales convencionales, que impide llegar a otros públicos. Este texto pretende mostrar algunas alternativas que puede adoptar la librería universitaria, en aras de fomentar la lectura de las publicaciones generadas por las universidades.

GASTÃO CRULS - TRAÇOS DE GÓTICO, BRASILIDADE E NEOFANTÁSTICO NA LITERATURA BRASILEIRA?
Authors: Sánchez-Verdejo Pérez Francisco Javier , Fernandes Gonçalves Filomena
Published: March 2021

O romance Frankenstein ou o Prometeu Moderno, escrito por Mary W. Shelley e publicado originalmente em 1818, tornou-se numa das obras basilares do imaginário gótico-fantástico, graças a inúmeras versões deste relato, quer no continente europeu, quer no continente americano, tanto na literatura, como no cinema e no teatro. O presente artigo tem como objetivo refletir sobre o modo como, em três dos seus contos, “Noites brancas” (1920), “No embalo da rede”(1923) e “O Espelho”(1938), o autor de vanguarda Gastão Cruls apresenta uma nova leitura do Gótico e se apresenta como precursor brasileiro do Neofantástico. Partindo da premissa de que o texto literário crulsiano ainda está a ser descoberto no meio académico europeu, este trabalho analisa os mecanismos literários com os quais Gastão Cruls desencadeia reações de medo, pasmo, suspense, insólito ou logro no leitor.
UM MONSTRO CHAMADO SOCIEDADE: DO GÓTICO POLÍTICO À DISTOPIA
Authors: Sasse Pedro
Published: March 2021

O gótico é indissociável do contexto político em que surge, e permanece, ao longo de sua trajetória, em diálogo com questões relacionadas a poder, controle e transgressão. Não obstante, há momentos em que comentários sociopolíticos assumem protagonismo e os mecanismos do gótico ganham fins retóricos para além da narrativa em si. Caleb Williams, de William Godwin, pode ser tomado como uma das primeiras manifestações desse uso do gótico, em que Fred Botting ressalta a construção de um Estado monstruoso e os horrores da opressão criada por uma justiça corrupta, e que David Punter chamará de “Political Gothic”. Apresenta-se, aqui, a hipótese de que os temas e estratégias presentes nesse uso do gótico se aplicariam também a outro gênero profundamente engajado com seu contexto político-social, a distopia. Buscamos, assim, apresentar como a ficção distópica dá continuidade a essa tradição de representações monstruosas da sociedade.
Do boards influence audit quality? A multidimensional analysis

Published: March 2021

This study investigates how corporate boards of directors influence the quality of external audit in a sample of service firms listed on the Amman Stock Exchange (ASE). We contribute to the literature by providing empirical evidence on the efficacy of the corporate governance mechanisms through corporate boards to influence audit quality in an emerging country setting (i.e., Jordan). According to Chua (1986), this is mainstream “market-based” accounting research. We regress multiple dimensions that capture the quality of financial statements’ audit on a group of board of directors (BoD) characteristics for total observations of 225 firm-year obtained for 45 companies during the period (2014-2018). Specifically, the multidimensional analysis of the response variable, audit quality, includes audit firm’s internationalization, audit fees, auditor tenure, and the number of licensed practitioners at the audit firm. Using multiple linear (Panel Least Squares – PLS) and logistic regression models, we document empirical evidence that audit quality is positively affected by the independence and size of boards but negatively affected by CEOs duality, while no influence of the board’s expertise on any measures of the audit quality. The study provides implications for policymakers and investors regarding the signals that firms can send regarding the quality of financial statements audit when complying with the best practices of corporate governance
Facemasks and COVID-19 case fatality rate
Authors: Fögen Zacharias
Published: March 2021

Mask mandates have been a globally used epidemiologic intervention
during the ongoing COVID-19 (coronavirus disease 2019) pandemic.
Although there is extensive supporting literature on the use of facemask
to reduce infection rates, its effect on the individual and course of
disease has remained controversial. The purpose of this study was to
find if mandatory masking influences the case fatality rate. This study
used data on case updates, mask mandates, and demographic status related
to the Kansas state, USA. The data were analyzed using a parallelization
approach based on county-level data.

The results showed that in Kansas during the summer of 2020, the
counties with mask mandate had significantly higher case fatality rates
compared to counties without mask mandate, with a risk ratio of 1.85
[1.51-2.10] for death with COVID-19.

Even after adjusting for the number of ‘protected persons’, i.e., the
number of persons who were not infected in the mask-mandated group
compared to the no-mask group, the risk ratio remained significantly
high at 1.52 [1.24-1.72]. By analyzing the excess mortality in
Kansas, this study determines that over 95% of this effect can solely
be attributed to COVID-19. The cause of this trend and the possible
connection between long-term effects associated with SARS-CoV-2 and
facemasks are explained in the theory herein by the ‘foegen effect’;
i.e., deep reinhalation of pure virions caught in the facemasks as
droplets can worsen the prognosis.

This finding suggests that the use of facemasks in COVID-19 pandemic did
contribute to an increase in the death toll counterintuitive of its
purpose, making mask mandates a highly debatable epidemiologic

Background: Cardiac resynchronization therapy (CRT) in heart failure
patients has been shown to improve patient outcomes in some but not all
patients. A few studies have identified that septal flash on imaging is
associated with response to CRT but there has yet to be systematic
review to evaluate consistency of the finding across the literature.
Methods: A search of MEDLINE and EMBASE was conducted to identify
studies which evaluate septal flash and its association with CRT
response. Studies that met the inclusion criteria were statistically
pooled with random-effects meta-analysis and heterogeneity was assessed
using the I statistic. Results: A total of nine
studies were included with 2,307 participants (mean age 76 years, 67%
male). Septal flash on imaging before CRT implantation was seen in 53%
of patients and the proportion of CRT responders from the included
studies varied from 52% to 77%. In patients who were CRT responders,
septal flash was seen in 40% of patients compared to 10% in those
deemed to be CRT non-responders. Meta-analysis of the eight studies
suggests that the presence of septal flash at pre-implant was associated
with an increased likelihood of CRT response (RR 2.55 95%CI 2.04-3.19,
p<0.001, I2=51%). Septal flash was also reported to be
associated with left ventricular reverse remodelling but the association
with survival and symptomatic improvement was less clear. Conclusions:
Septal flash is a well-defined and distinctive contraction pattern which
is consistently associated with CRT response and should be evaluated
when assessing for appropriateness of CRT device.

Maternal obesity may lead to epigenetic alterations in the offspring and
might thereby contribute to disease later in life. We investigated whether a
lifestyle intervention in pregnant women with obesity is associated with
epigenetic variation in cord blood and body composition in the offspring. Genome-wide DNA methylation was analyzed in cord blood from 208
offspring from the TOP-study, which includes pregnant women with obesity
randomized to lifestyle interventions comprised of physical activity with or
without dietary advice versus controls (standard of care). DNA methylation was
altered at 379 sites, annotated to 370 genes, in cord blood from offspring of
mothers following a lifestyle intervention versus controls (FDR<5%) when using the Houseman reference-free method
to correct for cell composition and three of these sites were significant based
on Bonferroni correction. These 370
genes are overrepresented in gene ontology terms including response to fatty acids
and adipose tissue development. Offspring of mothers included in a lifestyle
intervention were born with more lean mass compared to controls. Methylation at
17 sites, annotated to e.g. DISC1, GBX2, HERC2 and HUWE1,
partially mediates the effect of the lifestyle intervention on lean mass in the
offspring (FDR<5%). Moreover, 22 methylation sites were associated with
offspring BMI z-scores during the first 3 years of life (p<0.05). Overall, lifestyle
interventions in pregnant women with obesity are associated with epigenetic
changes in offspring, potentially influencing the offspring’s lean mass and
early growth.

YONI REI: CONSTRUCCIÓN Y DESTRUCCIÓN DE UN CUERPO POSTHUMANO
Authors: Cruz-Grunerth Gerardo
Published: March 2021

Pepe Rojo presenta en su literatura las más angustiantes visiones del mundo que transitan por la modernidad líquida (Bauman, 2003), a la vez que expresa las implicaciones del cuerpo posthumano (Braidotti, 1996; Ferrando, 2014). Con esto en consideración, en este artículo se abordará el cuento “Conversaciones con Yoni Rei” (1998), donde Rojo expone a una sociedad que ha trascendido tanto las limitaciones modernas como las restricciones éticas, lo que Bauman propone como rasgos de la modernidad líquida. En la narración, la vida de Yoni Rei es mostrada desde su etapa como embrión, el cual es vendido a una corporación internacional que modifica su cuerpo convirtiéndolo en cyborg y en un experimento fallido; y finalmente, en una celebridad monstruosa para el divertimento de la sociedad espectacularizada à la Debord (1967). La hipótesis de este artículo sostiene que el cuento de Rojo expresa la manera en que el cuerpo se convierte en la intersección de la violencia como norma en el mundo posthumano (violencia tecnológica, corporativa, social y autoinfligida); asimismo, que el protagonista es un ser que actúa en asociación con la ciencia y contra sí mismo, mientras pone en crisis su ser, con la construcción-destrucción de su cuerpo posthumano, que lo humaniza.
“German Parties” in the Russian Science of the 19th Century
Authors: Badalian Dmitrii A. 
Published: March 2021

The article is the devoted to the issue of German and Russian groups opposition that arose in various scientific institutions and associations in Russia in the 19th century, such as Russian Geographical Society, Russian Archeological Society, Imperial Public Library and others. The author examines the influence of those groups on the development of certain scientific lines of research, which demonstrated itself in the choice of the scientific language, scientific priorities and strategies, also very often – in the choice of scientific methodology, and finally – in the formation of scientific schools. All this confirms the ideas of the Slavophils and N.Ya. Danilevsky formulated in the 19th century regarding the influence on science of national consciousness and specific worldviews of the scientists.
Russia and Europe: What Are the Changes After Danilevsky?
Authors: Girenok Feodor I.
Published: March 2021

The article examines what according to Danilevsky was the disease of the Russian soul. The author compares the phenomena of the Russian intelligentsia and the intellectual. According to him, a modern intellectual is not a hero, not a critically thinking person. The intellectual is always opposed by a bureaucrat. But the intellectual has become a functionary of truth. The functionary of truth finds support of the power for the benefit of truth, and the bureaucrat finds support of the truth for the benefit of power. The article notes that since the time of Danilevsky Europe ceased to be Christian, and Russia ceased to be Europe. The author criticizes the concept of the three forces, introduced by Solovyov. As the result, he concludes that if power is not associated with the idea of justice, then its existence becomes illusory. Danilevsky gave the idea of justice priority over any right and any law.
Russian Philosophy and the Policy of Russia
Authors: Kazin Alexander L.
Published: March 2021

The article is devoted to the fundamental differences in the basic grounds of the Western, Eastern and Russian philosophy. When in the philosophy o the East God is perceived as the Absolute and the task of man and people is to follow His laws, the philosophy of the West adheres to consistent rationalization, which in its turn leads to the perception of God “from the outside” and notionally by an independent individual and in the course of certain evolution results in the rejection of the integral world view- “the truth is that there are many variants of truth”. Russian philosophy interprets the world as the unity of faith, thought and love that can be described as the principle of the believing mind. Due to this conciliar integrity this philosophy has the gift of speculation and the possibility to see spiritual light in the objective reality. It’s not possible to separate man, and especially his thought, from God, and this postulate makes Russia the land of future, which can preserve the world for the man, and the man for God.
The Birth of New Russian Meanings (the 10th – Beginning of the 13th Centuries)
Authors: Perevezentsev Sergey V.
Published: March 2021

The article examines the development of Christian truths by ancient Russian thinkers in the first centuries after the Baptism of Russia – from the end of the 10th to the 13th centuries. On the one hand, it shows the contradictory process of Christianization of different social groups of ancient Russian society. On the other hand, Russian spiritual and political thought of this period is analyzed, and the semantic content of the first Russian Christian writings is revealed, from the “Words on Law and Grace” by Metropolitan Hilarion of Kiev to Vladimir Monomakh’s “Teachings” and Daniel Zatochnik’s “Word”. The research allows us to say that in the course of understanding the main Christian dogmas, Russian spiritual and political thinkers substantiated new and eternal meanings of historical and posthumous existence.
Explaining the Maximal Intensity Exercise Performance of Young People
Authors: CHIA Michael
Published: March 2021

LANGUAGE NOTE | Document text in English; abstract also in Chinese.Explanations for children maximal intensity exercise fitness in the literature fluctuate between the incapacity of young children to generate energy anaerobically and a reduced need for the metabolic pathway. A number of propositions are advanced to explain young children's relative inaptitude in anaerobic performance in comparison with older children and adults. These range from a smaller quantity of active muscle mass to perform the anaerobic task, to the quality of the muscle which may not yet be energetically, chemically or neurogenically mature, in comparison to their older and more mature counterparts. No one single factor, whether quantitative or qualitative in nature, however, can account exclusively for the anaerobic fitness of young people. The other persuasive argument advanced is that children are less reliant than adults on the anaerobic energy pathway, for their energy supply. Arguments supporting such a contention include a swifter oxygen uptake response in children during high intensity exercise, a greater blood flow to muscle and greater oxygen extraction capability, and a blunted response to catecholamines during high intensity exercise. Either way, the evidence in the current literature is equivocal. Future research employing the use of non-invasive methods such as MRI to determine muscle fibre type, MRS to determine baseline energy substrates and utilisation rates during exercise, as well as mass spectroscopy to analyse oxygen uptake kinetics and other ventilatory responses during high intensity exercise, may help bring to the fore new knowledge to a most interesting area of research in children's exercise.有關兒童最大強度運動能力的文獻報導結果不一。有些學者認為兒童的無氧代謝的能力非常低下，而有些學者則認為是因為兒童對無氧代謝的需求較低。一些文獻闡述了年幼兒童無氧代謝能力較少年或成人低下的原因是由於肌肉的數量，尤其是無氧代謝能力較強的肌肉數量較少以及肌肉在能量代謝、生物化學和神經支配方面的成熟度較成年人低。而僅以某一單一因素，無論是肌肉數 量還是成熟度，都不足以解釋兒童無氧代謝能力的特點。另一些研究則表明兒童對無氧供能的需求量較成年人低，主要表現在兒童進行大強度運動時其攝氧量急劇上升，肌肉的血流量和氧攝取量明顯增加，以及運動中對兒茶酚胺的反應不敏感等。然而，迄今為 止對於兒童最大強度運動能力的特點仍不十分清楚，需作進一步的研究。應用無創傷性方法，如應用核磁共振成像法檢測肌纖維類 型、核磁共振光譜分析法測定運動中的能量物質及其利用率，以及質譜法分析大強度運動過程中攝氧量的動態變化和通氣量的變化 等，則將有助於提高和促進兒童體育科學研究。

Published: March 2021

LANGUAGE NOTE | Document text in English; abstract also in Chinese.Leisure activities, recreation, exercise, sport and sporting events are a part of life in society today. In a public school setting, it is the responsibility of the school/facility administrator to ensure safety for the participants and spectators or audience. Safe facilities, playing surfaces and equipment are a foundation for providing safety. Also, the administrator should be proactive in having a written emergency action plan for foreseeable situations, specifically, a medical emergency. Having a predetermined plan of action is imperative for the hosting school/facility. Some important aspects for an Emergency Action Plan (EAP) should include all personnel that will be part of the plan, scheduled mock practice sessions, availability of equipment, current certifications, etc. After implementing these aspects it is imperative that all individuals involved understand and know the details of the EAP in order for it to be effective and successful.隨著生活文化的轉變，康體活動已經成為了人們生活的重要部份。可是，當進行這些活動時一旦出現了意外事故，應該如何去處理較為恰當呢？本文試從緊急應變醫療角度分享經驗，給予有系統及效能的建議，以供參考。
