Herein we have reported a simple procedure for the synthesis of covalently grafted graphene oxide poly (vinyl alcohol) (PVA-g-GO). Later on, multiwalled carbon nanotubes (MWCNTs) were dispersed in this PVA-g-GO matrix by sequential stirring and sonication. Nanocomposites with varying weight percent of graphene oxide (GO) and multiwalled carbon nanotubes (MWCNTs) were synthesized. These nanocomposites have shown excellent thermal and mechanical stability. It also appears that presence of graphene oxide has assisted in dispersing the MWCNTs. Combine effect of GO and MWCNTs has resulted in the nanocomposite with electrical conductivity of 2.02E-09 S/cm.

Environmental stability of material properties is an important factor for its utilization for electronic devices. Gases in air such as oxygen can react chemically with material and cause degradation of its properties. This work reports on effect of air on thermoelectric properties of nanostructured n-type silicon-germanium (SiGe) alloy: a well-known high temperature thermoelectric material with superior properties. Phosphorous doped SiGe alloy was synthesized via mechanical alloying followed by hot-press and characterized by powder X-ray diffraction, scanning electron microscopy, and thermoelectric measurements. The average grain size of alloyed powder was in the range 50 - 400 nm. The reduction in grain size caused decrease in thermal conductivity of SiGe alloy (2.044 W/mK at ~ 900K). To study the effect of air on the transport properties of alloy measurements were carried out in presence of air and in inert (argon) atmosphere. Interesting results have been obtained and discussed with the available literature.

The objective of the present research is to enhance the wear behavior of silicon Nitride (Si3N4), Hafnium carbide (HfC) and Molybdenum Disulfide (MoS2) reinforced with Al 7075. The secondary particles like Si3N4 (2, 5 & 8), HfC (0.5, 1.25 & 2) and MoS2 (2, 3.5 & 5) are reinforced in base material Al7075 alloy using Powder Metallurgy (PM) technique. The sintered composites were characterized using Scanning Electron Microscope (SEM) and Energy Dispersive Spectroscopy (EDS). Dry sliding wear test was conducted for the sintered samples. The parameters of the experimentation are applied load (20 N, 40 N & 60 N), sliding velocity (1.5 m/s, 2 m/s & 2.5 m/s) and keeping sliding distance (1000 m) as constant. The results revealed that after reinforcing the secondary particles, it directly influenced the minimization of wear behavior. The worn surface analysis of the fabricated samples was viewed using SEM. Further, the process parameters of the wear behavior were optimized using Response Surface Methodology (RSM). Also, the maximum influencing process parameters were identified using analysis of variance (ANOVA).

Novel composites of graphene-beaded porous carbon nanofibers decorated with TiO2 (G/PCF/TiO2) were synthesized using an electrospinning method and their photocatalytic performance was demonstrated based on the degradation of methylene blue (MB) under visible light irradiation. The enhanced photocatalytic properties of G/PCF/TiO2 can be ascribed to the synergistic effect of graphene-beaded porous carbon nanofibers, which facilitates charge transfer, increases the light absorption in the visible range, as well as favors the adsorption of dye. The present strategy provides an effective strategy for the preparation of carbon-based composite and its application for high-performance photocatalysts.

The current research shows the influence of conducting substrates on surface morphology and its use for optical properties zinc oxide nanostructures. Samples were analyzed by energy dispersive (EDX), X-ray Diffraction (XRD), Field Emission Scanning Electron Microscopy (FE-SEM) and UV-Visible spectroscopy (UV-vis). The fabricated zinc oxide nanorods exhibit excellent crystalline quality and hexagonal wurzite structure. The Zinc oxide nano-walls and nanorods have crystalline size from 30 to 35 nm. FE-SEM images shows that nanowires and nano-walls grown on metal oxide coated substrates have good hexagonal structure. The zinc oxide nanorods fabricated on Pt coated thin film were highly dense as compared to other substrates coated with metal oxide. The Pt lattice parameter is nearby to Zinc oxide as compared to gold. The value of optical band gap energy (Eg) of zinc oxide nanorods grown on metal oxide was approximated to 3.35 eV that have the nearest value to bulk 3.37 eV. This confirms that Zinc oxide nanorods synthesized by aqueous solution technique have characteristics similar to other conventional techniques either bulk size or thin film nanorods.

Sybilla podglądana z kajuty. Obmapywanie Europy Mirona Białoszewskiego jako eschatologiczny „objazd”
Authors:   Instytut Literaturoznawstwa, Uniwersytet Śląski w Katowicach, Jochemczyk Mariusz
Published: February 2023

The author of the text concentrates on reading Miron Białoszewski’s “logbook”, which registers the writer’s belated journey on board the “Batory” ship around Europe. However, he is not interested in the tourist “view” of the continent and its textual explication. A three-week confinement in a cabin and occasional meditative “trips” ashore allow Białoszewski to make interesting testamentary, eschatological and “final”, reconciliations with himself, the world and life. The author of the article treats these practices as an intriguing “detour” – a departure from the main theme (“traveling”) of a literary work.

Published: February 2023

The considerations on geopoetics have so far emphasized the assumption that geographical experience determines the foundations for the creation of a literary work. The accepted premises for practicing spaceallowed the so-called topographic turn in the humanities. In the presented research concept, we are heading in a different direction, namely we would like to consider the following formulation: poetics precedes geographical experience. Therefore, we introduce the term reversed geopoetics. We assume that the word shapes the landscape and that it is thecause of spatial determination. We chose a void as the essence of our research, in which we perceive the lack of someone or something and wait for potential events. One can consider “nothing” instead of the ubiquitous “something”. We called this thread of thinking, entering a new epistemological area, “thegeography of absence”. In the considerations presented, we used elements of the semiotics of space.

Published: February 2023

Background: In the present study, we aimed to identify risk factors of poor prognosis for patients with acute coronary syndrome in the emergency department.
Methods: The study included 2667 patients, who were admitted to the Emergency Department of Chest Pain Center, Fujian Provincial Hospital, due to chest pain from January 1, 2017 to March 31, 2020. Logistic regression was used to identify factors of poor prognosis for patients with ACS in the ED. Receiver operating characteristic (ROC) curve was plotted to assess the performance of the multivariate logistic regression model. Subgroup analysis was used to analyze the difference of SBP in ACS patients with different characteristics.
Results: The final analysis included 2667 patients, of whom 2,057 patients (77.8%) had poor prognosis. STEMI (compared with UA) (OR=20.139; 95% CI:12.448-32.581; P < 0.001), NSTEMI (compared with UA) (OR=7.430; 95% CI:5.159-10.700; P < 0.001), respiratory rate ≥20 bpm (compared with <20 bpm) (OR=1.334; 95% CI: 1.060-1.679; P = 0.014), and use of antiplatelets (OR=1.557; 95% CI:1.181-2.053; P = 0.002) was associated with increased likelihood of poor prognosis for ACS patients in ED. SBP ≥140 mmHg (compared with<140mmHg) (OR=0.574; 95% CI: 0.477-0.690; P < 0.001) was associated with decreased likelihood of poor prognosis for ACS patients in the ED. The area under curve (AUC) of the predictive efficacy of logistic regression model was 0.825 (95% CI: 0.795-0.833, P < 0.001).
Conclusion: This study found that STEMI, NSTEMI, respiratory rate ≥20 bpm, and use of antiplatelets were associated with increased likelihood of poor prognosis for ACS patients in the ED. It also found that SBP≥140 was associated with decreased likelihood of poor prognosis. Our study may be useful for doctors to make clinical decisions for ACS patients.

Objective: To clarify the effects of percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG) on the clinical outcomes of patients with coronary heart disease (CHD) complicated with reduced ejection fraction heart failure (HFrEF) through meta-analysis.
Methods: Three major literature databases – PubMed, Web of Science, and Cochrane – were searched by search terms and the literature retrieval time was publications dating from January 2007 to December 2021. To search for observational studies and randomized controlled trials (RCT) comparing the efficacy of PCI and CABG in patients with CHD and HFrEF, the abstract or full text of the literature was read and the final included literature was determined, according to inclusion and exclusion criteria. The quality of the included literature was evaluated using the Ottawa scale and data extraction was further completed. Data analysis was made using RevMan5.4 and R4.1 software; relevant forest plots and funnel plots were made, according to the extracted data. Egger’s test was used to evaluate whether the data had publication bias. Outcomes were the major adverse cardiovascular events (MACE).
Results: A total of 10 studies were included and 11,032 subjects were included, made up of 5,521 cases of PCI and 5,511 cases of CABG. The results showed no significant difference between the two groups in cardiac mortality (CM) (RR=1.13, 95% CI 0.98-1.30, P = 0.10) and in overall all-cause mortality (ACM) (RR=1.12, 95% CI 0.92-1.37, P = 0.25). In the subgroup analysis of ACM, in the subgroups with left ventricular ejection fraction (LVEF) less than 35% and exceeding 35% and less than 50% (RR=1.12, 95% CI 0.92-1.37, P = 0.25) between the two groups, there was no statistical difference. However, among other MACE, compared with the PCI group, the CABG group had a lower risk of MACE (RR=1.58, 95%CI 1.49-1.70, P < 0.00001), myocardial infarction (MI) (RR=1.99, 95% CI 1.02-3.88, P = 0.04), heart failure (HF) (RR=1.29, 95% CI 1.17-1.43, P < 0.00001) and revascularization (RR=2.74, 95% CI 1.93-3.90, P < 0.00001). Finally in the CABG group, the risk of stroke or transient ischemic attack (TIA) was higher (RR=0.71, 95% CI 0.58-0.86, P = 0.0006) than the PCI group.
Conclusions: The mortality rates of PCI and CABG were similar in patients with CHD complicated with HFrEF. Compared with PCI, CABG had a lower incidence of MACE, MI, HF, and revascularization, and a higher incidence of stroke or TIA.
The Book of Paroemias of 1775 as a specimen of the printing-house production at al-Shuwayr
Authors: Frantsouzoff Serge
Published: February 2023

In the article the Book of Paroemias issued in al-Shuwayr in AD 1775, purchased in Beirut in December of 2005 and kept now in a private collection of St. Petersburg is examined in detail. The author gave a full description of that copy from the point of view of its design, state of preservation and also of its contents. He traced the foundation of a monastery of St. John the Baptist in al-Shuwayr on the turn of the 17th – 18th century AD, its turning into a stronghold of the Uniates separated from the Antiochian Orthodox Church, who adopted the Charter of St. Basil the Great, and the formation of a printing house in Arabic script upon it that published its first book in AD 1734 and existed till AD 1899. It is noted that one of the peculiarites of its book production consisted in the elegance of its script fabricated by Abdallâh b. Zhâhir, hereditary jeweler and its creater. It is established that the Book of Paroemias published in al-Shuwayr in AD 1775 was mentioned in the itineraries of C.-Fr. Volney and was thoroughly described in the Bibliotheca Arabica by Ch. Fr. de Schnurrer. The correspondence of that liturgical book to the Orthodox canon is demonstrated. Besides that, the attention is paid to the fact that the Uniated, who did not want to break with the East Christian tradition, spread among their flock the Roman Catholic theological doctrine through different ways, including books printed in al-Shuwayr.
From the poetic heritage of Sulayman, bishop of Gaza (10th–11th cent.)
Authors: Melikyan Sofia , Edelshtain Anastasia
Published: February 2023

The publication presents a commented interlinear and literary translation of two qasidas (poems) from the Divan (collection) of the first known Arab Christian poet – Sulayman al-Ghazzi, bishop of Gaza in Palestine (Xth-XIth cent.). His poetic work is the earliest attempt at using the metrical and stylistic tools of classical Arabic poetry for purely Christian subjects. The Divan also contains multiple autobiographical data and important historical evidence of Christian persecution under the Fatimid caliph al-Hakim, including the destruction of the Church of the Holy Sepulchre in Jerusalem. Despite their unique significance, very few of Sulayman’s poems have been translated into a modern language. The two selected qasidas belong to the opposite traditional genres of Arabic poetry – reproach and praise. In the first one the Jews who rejected Christ are targeted; the other one is focused on righteous Christians and their liturgy. In addition, the first qasida is rich in biblical allusions and quotations, loosely reworked by the author in a poetic vein, and the second one gives a detailed description of the divine service and is therefore a valuable evidence of the liturgical life of Palestinian Christians in Sulayman’s era.

Authors: Bliznetsova Yuliya
Published: February 2023

By historical and pedagogical analysis a complex of ideas that represents the core of V.V. Zenkovsky’s Christian-anthropological concept of education was revealed. The conceptual core includes ideas: Christian anthropology, Orthodox culture, holistic synthesis. These ideas determine the content of the basic pedagogical concepts, the goals of education, the principles and content of education.Person in the Christian-anthropological concept of education V.V. Zenkovsky is the bearer of the Image Divine, the main expression of which is the beginning of personality. Education in the concept of the scientist is defined as helping the child in individual spiritual growth, in revealing the the Image Divine and mastering the “gift” of freedom through churching. The goal of education is to restore the integrity of a person.The following principles of the Christian-anthropological concept are defined: recognition of the Image Divine as the beginning of personality; Christocentricity; a holistic personality; hierarchies in the human constitution; individuality; catholicity; freedom; churching. The content of education in the concept of V.V. Zenkovsky covers all aspects of a person and includes: religious, intellectual, physical, education of discipline, moral, aesthetic, sexual, social, national education. Religious education has a priority among other directions, as it is aimed at developing the spiritual sphere of the individual, which has primacy over the psychophysical in accordance with the principle of hierarchy in the human constitution.
Materials and arts of expression in traditional Vietnamese lacquer
Authors: Van Minh Nguyen
Published: February 2023

The material of traditional lacquer is Son Ta (“Ta”: paint lacquer). Son Ta material, with its preeminent features in terms of reason, is also a deep and warm "feeling". The art of expressing the beauty of the material in the work is also a firm and profound grasp of the specific characteristics and techniques of the material, making the material an irreplaceable element of the work. On the contrary, with the structure of the work through his visual language, the artist must affirm that only that material, only, conveys the voice of the image and techniques expressed in the work. In other words, the material is the content, and the art of expression is the form of the work. The content determines the form and orientation of the chosen form and conveys the language of expression. And vice versa, the form reflects the content, revealing and clarifying the content in the best and most effective way. This is a dialectical and interactive relationship. It is this relationship that makes up the whole of the work in traditional Vietnamese lacquer.

We report a case of 64-year-old female, presented with decreased vision in left eye, for 3 months. Her vision was 20/30, N6 in right eye and 20/200 and N36 in left eye. She had nuclear sclerosis grade 2 and optical coherence tomography showed stage-2 macular hole in left eye. The macular hole diameter was 286 microns and the basal dimeter of 486 microns. The patient underwent cataract surgery with intraocular lens implantation in left eye. At 1 month, an inner retinal layer apposition was noted with subsequent inner to outer retinal apposition, resulting in complete spontaneous closure at the 3rd month follow up with visual acuity gain of 20/40, N8. This case highlights that stage-2 macular hole can close spontaneously with relief of vitreomacular traction.

Covid-19 and obesity
Authors: Makhlouki Houria
Published: February 2023

The Covid-19 virus has affected almost 35 million people resulting in the death of more than a million people. It started in 2019 in China and spread quickly worldwide. It has become the most extensive healthcare concern of the 21st century and has effectively caused trouble and loss to human life and challenges to health authorities as well. The Covid-19 virus can spread from one person to another, but older and obese people are at higher risk of severe disease and death. Research has shown that obese people are at higher risk of getting Covid and becoming severely ill because they have less capacity to fight off the diseases and infections than healthy weight people. One of the biggest reasons behind this is that the immune system weakens with increasing weight, which makes the obese person more susceptible to the disease. Consequently, the immunologic changes can be both in younger obese and older people. In addition, research has also shown that obese people store a lot of substances within their fat cells. They release more substances than they produce. This substance circulate into the blood and bind with the immune cells, which release the inflammatory factors. According to new research, obese people have to face a tough time fighting the Coronavirus even if they have a milder form of the virus. The research of more than 500 corona patients, teens and adults who were obese had severe symptoms as compared to those who were healthy weight. Certain lifestyle changes keep the body healthy and strengthen the immune system, especially during this pandemic, such as: balanced and healthy food, exercising and proper sleep. Because of the absence or lack of these practices can increase obesity and weight. On the other hand, weight loss can also improve blood pressure cholesterol levels and improve heart health. It can also reduce the severe Covid illness.
Obesity and bone health: key 2020–2022 highlights and implications
Authors: Marks Ray
Published: February 2023

Sound bone health is crucial for life affirming activities, but is bone physiology impacted in the face of excess body weight? Since fractures and osteoporosis are on the rise, is obesity a risk factor for, as well as a possible negative albeit remediable correlate of bone health in the older adult? To examine this premise the PUBMED and GOOGLE SCHOLAR data bases were sourced for relevant data published between January 1 2020 and November 1 2022 in an effort to capture post COVID-19 possible research observations on the topic. These data bases show while a pervasive idea has been that obesity may be beneficial in some respects to bone mineral density attributes and impart fracture protection, several current publications tend to portray a negative impact of obesity on bone health via multiple proposed mechanisms. However, the research points to a strong need for continued research as well as clinical vigilance of vulnerable individuals both young and old in a period where obesity rates in all age groups appear to be on the rise, along with cases of bone fragility and osteoarthritis that can both foster high morbidity and mortality rates and possibly more challenging weight issues in the face of painful fractures or joint derangement.

Fish farming in Senegal encounters many difficulties, especially during the first life stages, which are more demanding for food and more sensitive to variations in the physicochemical parameters. Most of the species of aquaculture interest have offspring whose size at birth is very small, thus requiring a particular rich food adapted to the size of the mouth (e.g. live preys which are very rich in nutritive reserves). The objective of this study was to set up a production system of live prey, daphnia for the feeding of fish fry. It consisted of culturing microalgae that were used to fed daphnia reared to fed the fry of the African catfish, Clarias gariepinus. The temperature and dissolved oxygen content in the culture and rearing media were monitored throughout the experiment. The results on species identification showed that the cultured microalgae and reared daphnia species are Microcystis sp and Daphnia magna, respectively. Analyses of algal biomass and daphnia abundance show an increase in these parameters with time. Temperature variations do not affect algal biomass, daphnia abundance and fry growth. On the other hand, a decrease in dissolved oxygen content below a certain threshold (6mg/l) leads to a decrease in algal biomass and daphnia abundance. Among the three feeding rates 1.5g, 3g, 4.5g (the equivalent of 0.5L, 1L, and 1.5L of microalgae, respectively) that were used to feed daphnia, the feeding rate of 3g of biomass corresponding to 1L is more adequate as it gave the best production. The comparison of the effects of the types of feed shows that live daphnia give better growths of C. gariepinus fry than the artificial feed, which may be due to their adequate size and nutrient richness. Thus, this study contributes to the establishment of live prey production systems to boost local aquaculture development and demonstrates the importance of daphnia for the feeding of early fish life stages.
