Leather is one of the most efficient, natural and renewable resource, a unique and highly versatile material which contributes to the quality of everyday life and has done so for centuries. Due to its resilience, comfort and beauty, leather has played an important role since the beginning of times in satisfying man's clothing and decorative needs. Technically speaking, leather is a fundamental output of the leather tanning industry. Tanneries recover the hides and skins that are discarded by-products of the food industry producing meat for human consumption and convert them into leather, a stable material with a wide range of applications in downstream sectors of the consumer goods industry. Footwear, garment, furniture, automotive and leather goods industries are the most important outlets for EU tanners’ production. More specifically, the footwear Directive provides a definition of “leather”, which reserves the use of the word and its synonyms to products resulting from the processing of animal remains that retain the natural structure of the fibres undamaged.

Despite successes, many problems are encountered with small-seed crops (sorghum, turnip, mustard, linen, etc.), for many of them there are not enough recommendations of regulations and other normative and technological documentation. The article is devoted to ways of improving the drying process of freshly harvested grain. It is known that during post-harvest processing, small-seeded crops undergo a certain thermal effect at certain stages of it. First of all, this regards, drying and cooling processes. Meanwhile, heat treatment is a complex technological process in which numerous physical-mechanical and biochemical changes, sometimes irreversible, occur in oil seed. In addition, heat treatment is the most energy-efficient. Timely and proper drying of grain not only increases its stability during storage, but also improves food and seed quality of grain. As a result of drying, post-harvest maturing is accelerated, humidity is leveled and technological properties change. Drying has a positive effect on the yield and quality of grain and products of its processing. To our regret, there are almost no studies of drying process of small-seeded crops grown in Ukraine. Meanwhile, drying is an important link in the post-harvesting process of corn. The paper gives recommendations on drying technology of crops (sorghum) and oilseeds (turnip, mustard, flax) of smallseeded food crops in grain-harvesting enterprises. The basic scheme of technological line of heat treatment of small-seeded crops and recommendations for reducing energy intensity and increasing the efficiency of heat treatment and improving their quality are developed. The main purpose of this article is to familiarize a wide range of specialists in the field of post-harvest processing and storage of grain with drying regimes and the scheme of technological drying line of small-seeded crops.

The construction and selection of a suitable bijective function, that is, substitution, is now becoming an important applied task, particularly for building block encryption systems. Many articles have suggested using different approaches to determining the quality of substitution, but most of them are highly computationally complex. The solution of this problem will significantly expand the range of methods for constructing and analyzing scheme in information protection systems. The purpose of research is to find easily measurable characteristics of substitutions, allowing to evaluate their quality, and also measures of the proximity of a particular substitutions to a random one, or its distance from it. For this purpose, several characteristics were proposed in this work: difference and polynomial, and their mathematical expectation was found, as well as variance for the difference characteristic. This allows us to make a conclusion about its quality by comparing the result of calculating the characteristic for a particular substitution with the calculated mathematical expectation. From a computational point of view, the thesises of the article are of exceptional interest due to the simplicity of the algorithm for quantifying the quality of bijective function substitutions. By its nature, the operation of calculating the difference characteristic carries out a simple summation of integer terms in a fixed and small range. Such an operation, both in the modern and in the prospective element base, is embedded in the logic of a wide range of functional elements, especially when implementing computational actions in the optical range, or on other carriers related to the field of nanotechnology.

The historical polyethnicity of the Slovak society and the connected problems of the interrelations of cultures, ethics, interpersonal relations, are reflected in the works of modern Slovak prose. They are represented most clearly in the novels of middle generation writers P. Rankov, S. Lavrík, P. Krištúfek. They dwell upon the dramatical events of the 20 th century. They cover wide range problems, from the fruitful coexistence of various ethnic groups and their representatives to national contradictions and racial repressions. The artistic quality of the mentioned works, their composition, the way of narrating, the type of the main character, can be highly evaluated. For example, in a novel by P. Rankov the plot, in spite of its linearity, is a chain of episodes in the span of 30 years from the life of the main characters. It reflects not only their fates, but also the historical and political changes of the world they live in. The main female character of a S. Lavrík ’s novel narrates about everyday life and tragedies in the lives of the dwellers of a Slovak town in the Slovak Republic during the war. P. Krištúfek in his novel focuses on several decades from the life of a Slovak-Jewish family and dwellers of a Slovak provincial society with types and relations specific for this milieu.

Abstract The electronics supply chain is being increasingly infiltrated by non-authentic, counterfeit electronic parts, whose use poses a great risk to the integrity and quality of critical hardware. There is a wide range of counterfeit parts such as leads and body molds. The failure analyst has many tools that can be used to investigate counterfeit parts. The key is to follow an investigative path that makes sense for each scenario. External visual inspection is called for whenever the source of supply is questionable. Other methods include use of solvents, 3D measurement, X-ray fluorescence, C-mode scanning acoustic microscopy, thermal cycle testing, burn-in technique, and electrical testing. Awareness, vigilance, and effective investigations are the best defense against the threat of counterfeit parts.

The existing legislation determines the education as "an integral and focused process of teaching and upbringing, which represents a socially important value and shall be implemented so as to meet the interests of the individual, the family, the society and the state". However, even in this part, the meaning of the notion ‘socially significant benefit is not specified and allows for a wide range of interpretation [2]. Yet the more inconcrete is the answer to the question – "who and how should determine the interests of the individual, the family and even the state?" The national doctrine of education in the Russian Federation, which determined the goals of teaching and upbringing, the ways to attain them by means of the state policy regulating the field of education, the target achievements of the development of the educational system for the period up to 2025, approved by the Decree of the Government of the Russian Federation of October 4, 2000 #751, was abrogated by the Decree of the Government of the Russian Federation of March 29, 2014 #245 [7]. The new doctrine has not been developed so far. The RAE Academician A.B. Khutorsky believes that the absence of the national doctrine of education presents a threat to national security and a violation of the right of citizens to quality education. Accordingly, the teacher has to solve the problem of achieving the harmony of interests of the individual, the family, the society and the government on their own, which, however, judging by the officially published results, is the task that exceeds the abilities of the participants of the educational process.  The particular concern about the results of the patriotic upbringing served as a basis for the legislative initiative of the RF President V. V. Putin, who introduced the project of an amendment to the Law of RF "About Education of the Russian Federation" to the State Duma in 2020, regarding the quality of patriotic upbringing [3]. Patriotism, considered by the President of RF V. V. Putin as the only possible idea to unite the nation is "THE FEELING OF LOVE OF THE MOTHERLAND" and the readiness for every sacrifice and heroic deed for the sake of the interests of your Motherland. However, the practicing educators experience shortfalls in efficient methodologies of patriotic upbringing, which should let them bring up citizens, loving their Motherland more than themselves. The article is dedicated to solution to this problem based on the Value-sense paradigm of upbringing educational dynasty of the Kurbatovs [15].

Mutation BRAFV600E is highly specific for papillary thyroid carcinoma. It’s detected in 40-70% of all papillary thyroid carcinoma cases. Moreover this mutation is noticed in anaplastic carcinoma in 40-50%.This fact gives a chance to select patients and provide targeted therapy with multi-kinase inhibitors in cases of unresectable anaplastic carcinoma. The influence of BRAF V600E mutation for response to radioactive iodine therapy requires more evidence-based research. Existing methods for determining the BRAFV600E mutation have different accuracy, availability and cost. Other methodological aspects are also associated with the sample preparation of biological material, the quality of reagents, and the cross-validation of research results. In this review, on the basis of our own experience and literature data, the indications for determining the mutation of the BRAFV600E gene in clinical practice are refined, and a comprehensive comparative analysis of modern research methods has been conducted. This review is focused on a wide range of specialists of different types: oncologists, endocrinologists, radiologists, pathologists, and biologists.

Aim & objective: To review the applications and production studies of reported antileukemic drug L-glutaminase under Solid-state Fermentation (SSF). Overview: An amidohydrolase that gained economic importance because of its wide range of applications in the pharmaceutical industry, as well as the food industry, is L-glutaminase. The medical applications utilized it as an anti-tumor agent as well as an antiretroviral agent. L-glutaminase is employed in the food industry as an acrylamide degradation agent, as a flavor enhancer and for the synthesis of theanine. Another application includes its use in hybridoma technology as a biosensing agent. Because of its diverse applications, scientists are now focusing on enhancing the production and optimization of L-glutaminase from various sources by both Solid-state Fermentation (SSF) and submerged fermentation studies. Of both types of fermentation processes, SSF has gained importance because of its minimal cost and energy requirement. L-glutaminase can be produced by SSF from both bacteria and fungi. Single-factor studies, as well as multi-level optimization studies, were employed to enhance L-glutaminase production. It was concluded that L-glutaminase activity achieved by SSF was 1690 U/g using wheat bran and Bengal gram husk by applying feed-forward artificial neural network and genetic algorithm. The highest L-glutaminase activity achieved under SSF was 3300 U/gds from Bacillus sp., by mixture design. Purification and kinetics studies were also reported to find the molecular weight as well as the stability of L-glutaminase. Conclusion: The current review is focused on the production of L-glutaminase by SSF from both bacteria and fungi. It was concluded from reported literature that optimization studies enhanced L-glutaminase production. Researchers have also confirmed antileukemic and anti-tumor properties of the purified L-glutaminase on various cell lines.


In his philosophical writings, Coleridge increasingly developed his thinking about imagination, a symbolizing precursor to contemplation, to a theory of contemplation itself, which for him occurs in its purest form as a manifestation of ‘Reason’. Coleridge is a particularly challenging figure because he was a thinker in process, and something of an omnimath, a Renaissance man of the Romantic era. The dynamic quality of his thinking, the ‘dark fluxion’ pursued but ultimately ‘unfixable by thought’, and his extensive range of interests make essential an approach that is philosophical yet also multi-disciplinary. This is the first collection of essays to be written mainly by philosophers and intellectual historians on a wide range of Coleridge’s philosophical writings. With a foreword by Baroness Mary Warnock, and original essays on Coleridge and Contemplation by prominent philosophers such as Sir Roger Scruton, David E. Cooper, Michael McGhee, and Andy Hamilton, this volume provides a stimulating collection of insights and explorations into what Britain’s foremost philosopher-poet had to say about the contemplation that he considered to be the highest of the human mental powers. The essays by philosophers are supported by new developments in philosophically minded criticism from Coleridge scholars in English departments, including Jim Mays, Kathleen Wheeler, and James Engell. They approach Coleridge as an energetic yet contemplative thinker concerned with the intuition of ideas and the processes of cultivation in self and society. Other essays, from intellectual historians and theologians, clarify the historical background, and ‘religious musings’, of Coleridge’s thought regarding contemplation.
