On Two Factors of National Identity: Orientation and Social Structure of Society
Authors: VOSKANIAN Ashot 
Published: November 2022

Given peculiarity of Armenian history, the Armenian political thought for centuries debated around geopolitical orientation between neighboring great powers. In post-Soviet reflections, however, the emphasis has been moved towards self-reliance, and the very principle of political orientation was questioned. The attitude towards Israel Ori, whose name was viewed as a symbol of the principle of orientation, became the locums for determining the political-ideological disposition of debater, as well as understanding their approaches towards different concepts of national identity.
A brief comparison between the conceptual paradigms of two renowned historians Ashot Hovhannisyan (1887-1972) and Leo (Arakel Babakhanyan, 1860-1932) in relation to their attitude towards Israel Ori aims to demonstrate that questioning of the very principle of orientation has much deeper roots in Armenian historical studies than commonly is believed. It also illuminates the complex relationship between principle of orientation and desired model of social structure of society, which these two classics have revealed in rather different ways.
David the Invincible: Philosophy as a Lifestyle
Authors: PETROSYAN Silva 
Published: November 2022

The most outstanding representative of the history of Armenian philosophy, Neoplatonic thinker of the V-VI centuries, David the Invincible continues the tradition reached the peak of its development in the Ancient Greece by Socrates and Plato, according to which philosophy is first of all a way of life, a means of transformation and perfection of the human being. Following the principles of the Greek Paideia David considers philosophy as a care of the soul, in which theory and practice are intertwined, and cognition of the world depends on the efforts of self-improvement by a subject. Author shows that in David’s definitions of philosophy is clearly seen the significance of self-formation, “zardarum” in the process of reality formation, comprehension or rethinking. It is also mentioned that we can use Michel Foucault’s notion of the “care of the soul” and Pierre Hadot’s notion of “spiritual practices’’ to characterize David’s optimistic philosophy, which was developed further in the theories of Armenian thinkers Grigor Narekatsi, Grigor Magistros, Hovhannes Imastaser, Arakel Sjunetsi, etc.
Essential Features of Electoral Process of Armenia in the Context of Current Changes in the Electoral Code
Authors: GHARIBYAN Anahit 
Published: November 2022

A constitutional referendum was held in Armenia on 6 December 2015. The amendments to the constitution changed the country from having a semi-presidential system to a parliamentary republic, with the changes planned to take place during the 2017–18 electoral cycle. The results of the referendum determine not only the current changes in the electoral code, but also the necessity and effectiveness of the new electoral system.
Particularly, by replacing the majoritarian system to the proportional system and by increasing the representativeness of the parliament for some groups, we can create basis for the further development of the country. Above all in the article we discussed the main factors that have a big impact on the voting behavior of the citizens.
Methodological Importance of the Notion of Divine Revelation in a Historical Perspective
Authors: MEZEI Balázs M. 
Published: November 2022

I offer an overview of the relevance of the notion of divine revelation to the methodology of the sciences. The notion of revelation is to be considered in the framework of a well-formed philo­sophical theory. In such a theory, the theological notion of revelation is important as well, because as a historically evolving notion it has contributed, in its own fashion, to the formation of other sciences. The method the notion of revelation entails is instructive for the methodological presuppositions of the sciences. Most importantly, the dynamism given in the notion of revelation to produce genuine newness – ad intra as well as ad extra – appears to be the decisive methodological factor defining scientific methodology. I also reflect on the importance of various forms of knowledge – apodicticity, certainty and probability – as they appear in the notion of revelation and define scientific forms of knowledge in a historical as well as logical fashion. Finally, I show the place of the methodological discussion in an overall view of revelation as a well-formed philosophical theory.

Published: November 2022

In this paper, the preparation of potassium carbonate modified SiO2-Al2O3 composite aerogel, the carbonation characteristics of K2CO3 and the decarburization characteristics of regeneration cycle were studied. The influence of loading rate on CO2 adsorption was studied by using a fixed bed reactor, and the microstructure of the samples was analyzed by combining SEM and BET. The results show that during the alkali fusion sintering of Na2CO3, the Si-O-Si and Si-O-Al bonds break, the crystal structure is destroyed, and the covalent bond of mullite is transformed into the ionic bond of nepheline. Through orthogonal test, taking the specific surface area of aerogel as the measurement index, the optimal calcination conditions are determined as follows: 900 ℃, reaction for 60 min, Na2CO3 addition ratio of 0.5. The more K2CO3 is loaded, the less the corresponding active sites on the surface of the carrier. When the loading is 30%, the maximum CO2 adsorption capacity is 2.86 mmol·g–1. Excess K2CO3 will plug the pore structure, destroy the diffusion of CO2, and reduce the diffusion and utilization efficiency. The percentage of mesoporous pore volume decreased from 94.21% to 89.32%, indicating that the active component K2CO3 was mainly filled in the mesoporous. After 10 cycle regeneration tests, the CO2 adsorption capacity of the adsorbent decreased by 10.49%. The pore structure of the adsorbent was stable and the decarburization performance was excellent.

Genetically modified trees with improved abiotic stress resistance - recent accomplishments. A review.
Authors: Sozoniuk Magdalena , Kowalczyk Krzysztof 
Published: November 2022

Great progress has been made within the last few years in terms of abiotic stress resistance improvement of forest trees. The application of genetic modification techniques allows developing trees displaying superior growth under various abiotic stresses such as high salinity, drought, low temperature, and environmental pollution. Poplar, which is an important agroforestry crop, is especially responsive to improvement through genetic engineering. With the view of imminent environmental changes, the application of transformation techniques to forestry breeding seems to be an attractive perspective. Here, we review the most recent achievements of researchers developing genetically modified (GM) poplar trees displaying enhanced performance under unfavorable experimental conditions.
Assessment of Poland food security in the context of agricultural production in 2010–2020

Published: November 2022

This article aims to description food security and its measurement method and analyse the agricultural production status and food self-sufficiency in 2010–2020. Currently, Poland in 2020 ranks 59th globally and fifth in the European Union in terms of utilised agricultural areas. Considering the population of agricultural workers, Poland are the first in the European Union. Results of studies concerning the production and consumption of basic agricultural raw materials indicate that Poland is a country mostly featuring a food production surplus. From 2010 to 2020, its level of self-sufficiency to the extent of basic cereals was variable; however, grain production surplus was recorded in the analysed period. Similar observations were made for the production of potatoes and vegetables. Only in some years did fruit production show a deficit or was at the domestic consumption level. As regards milk and eggs, Poland was self-sufficient in the whole analysed period, and the dynamics of increase in the surplus of milk and eggs was proportional to the 2010 year. From 2010 to 2020, Poland recorded a high surplus of poultry meat and beef that increased every year using a dynamic approach. The level of self-sufficiency to the extent of pork supplies was highly varied. From 2010 to 2015, a deficit occurred that decreased year on year, and from 2018 to 2020, it reached a surplus of 71 000, 62 000 and 40 000 tonnes, respectively. Surveys regarding Poland’s balance of foreign trade in agri-food products did not confirm food self-sufficiency in 2010; however, from 2015 to 2020, the balance was positive and was growing throughout the survey period, which means that Poland exported more agri-food products than it imported. Many households representing the part of the society with the poorest income declare they are not able to eat red meat or poultry every other day. A systematic reduction in the calorific value of food consumed in Polen is also puzzling as lower than the reference (2350 kcal), and in 2019 it reached a distressing daily intake value of 1999 kcal per capita.

The aim of the study was to determine the influence of habitat, cultivar and developmental growth stage on catalase activity in soil under two amaranth cultivars – Rawa (Amaranthus cruentus L.) and Aztek (Amaranthus hypochondriacus × Amaranthus hybridus L.). In a 3-year field experiment (2013–2015), amaranth’s plants were grown in a wide-row spacing on the soil of the good wheat complex in south-eastern Poland (50°71'N, 23°04'E). The field experiment included 4 variable factors: weather conditions; selected amaranth growth stages (5-leaf, full flowering and seed maturity stages); NPK dose combinations (I: 40 kg N ∙ ha–1, 30 kg P ∙ ha–1, 30 kg K ∙ ha–1; II: 60 kg N ∙ ha–1, 40 kg P ∙ ha–1, 40 kg K ∙ ha–1; III: 80 kg N ∙ ha–1, 50 kg P ∙ ha–1, 50 kg K ∙ ha–1; IV: 120 kg N ∙ ha–1, 70 kg P ∙ ha–1, 70 kg K ∙ ha–1) and two cultivars (‘Rawa’ and ‘Aztek’). No pesticides are applied in the cultivation due to the absence of pathogens and pests of this plant in Poland. Plant protection was limited to reducing weed infestation twice. The conducted research showed that weather conditions were the main factor affecting catalase activity in the soil under amaranth cultivation, followed by other factors, such as fertilization, cultivar and growth stage. All the analyzed factors proved to exert a significant impact on organic matter content in the soil, while only the applied NPK fertilization had effect on sorption capacity. Moreover, it was found that the cv. Aztek positively influenced the activity of catalase and humus accumulation in the soil in comparison to the cv. Rawa. The beneficial effect of amaranth on the soil environment and its enzymatic activity was ascribed to the lack of introduced pesticides.

Abstract

OBJECTIVE
To evaluate efficacy of a novel vaccine against rabbit hemorrhagic disease virus 2 (RHDV2) in domestic rabbits.

ANIMALS
40 New Zealand White rabbits obtained from a commercial breeder.

PROCEDURES
Rabbits were vaccinated and held at the production facility for the duration of the vaccination phase and transferred to Colorado State University for challenge with RHDV2. Rabbits were challenged with oral suspensions containing infectious virus and monitored for clinical disease for up to 10 days. Rabbits that died or were euthanized following infection were necropsied, and livers were evaluated for viral RNA via RT-PCR.

RESULTS
None of the vaccinated animals (0/9) exhibited clinical disease or mortality following infection with RHDV2 while 9/13 (69%) of the control animals succumbed to lethal disease following infection.

CLINICAL RELEVANCE
The novel vaccine described herein provided complete protection against lethal infection following RHDV2 challenge. Outside of emergency use, there are currently no licensed vaccines against RHDV2 on the market in the United States; as such, this vaccine candidate would provide an option for control of this disease now that RHDV2 has become established in North America.
Survival following upward cerebellar herniation in a neonate: a case report
Authors: King Adam , Brown Kelly , Banerjee Rupjani 
Published: November 2022

Background:
Herniation of the brain within the cranial vault is rare in newborns and carries a high mortality. Reported cases show herniation downward, through the foramen magnum. This case report uniquely describes upward herniation through the cerebellar tentorium.

Case Presentation:
A male infant born at 38 weeks gestation had a postnatal collapse at 17 hours. There were no spontaneous movements with hypotonia, reduced reflexes, nystagmus, and seizures. Cranial ultrasound showed diffuse changes in the posterior fossa, with acute cerebellar hematoma confirmed on MRI scan with significant mass effect, herniating the right cerebellar hemisphere in an upward direction. The baby was initially managed on a palliative care pathway but stabilized with clinical and MRI improvements. He survived to discharge and has mild neurological deficits at 14 months of age.

Conclusion:
Herniation can occur in an upward direction, evoking cerebellar signs like nystagmus in a neonate and it appears to be potentially survivable.
