Published: January 2023

Employment is one of key parameters of the economy, which characterizes its efficiency, possibility of using the labour potential and growth of population’s well-being. The level of employment is the most important indicator of the effectiveness of socio-economic policy of the state. A high level of employment in high-tech and science-intensive business areas is a driver of sustainable economic development of countries, increasing labour productivity, ensuring leadership in the market, and reducing the productions costs. Thus, the assessment of the effectiveness of population employment in high-tech and science-intensive service areas is significant today, as it is a comprehensive assessment of the country’s development, its current state in high technologies and further prospects for working with them. The research purpose consists in determining the maximum, most effective value of the population employment efficiency index in high-tech and science-intensive service spheres based on cross-country cluster analysis. The sample of countries all over the world were divided into 3 clusters, taking into account the rating value of the following indices: employment in high- and medium-high-tech production sectors and science-intensive business service spheres; enterprises that conducted training to develop / improve the ICT skills of their personnel; new registered enterprises. During the research there were statistical data analysis, cluster analysis using Ward’s method and software Statgraphics, optimization method using Frontier Analyst software. As a result, the efficiency of population employment in high-tech and science-intensive business service sectors of 36 countries in 2021 was determined, and accordingly reference countries with high population employment in this research sphere were identified. The potential reserves for increasing the targeted value of the population employment index in high-tech and science-intensive sectors were also characterized. The obtained results can be useful for business managers, they can adopt the experience of doing business in countries with more effective indicators, with the aim of developing employees, providing them with new training and knowledge that will facilitate doing business in the future.

Authors: DALKES Melek , KORKMAZ Mehmet Seren
Published: January 2023

Heyelanlar yaşanan doğal afetler arasında en başta gelenlerdendir. Karadeniz Bölgesi’nde heyelanlar yaygın olarak görülmektedir. Türkiye’de en fazla heyelanın meydana geldiği il Trabzon’dur. Heyelanlar sebebiyle gerçekleşen kayıpları en aza indirmek amacıyla heyelan duyarlılığı yüksek olan sahaların önceden belirlenmesi için heyelan duyarlılık haritalarının hazırlanması gerekmektedir. Bu çalışmada, Analitik Hiyerarşi Süreci (AHS) ve Frekans Oranı (FR) yöntemleri kullanılarak, Trabzon ilinin Akçaabat ve Düzköy ilçe sınırları içerisinde, heyelan duyarlılığı yüksek olan sahaların belirlenmesi için heyelan duyarlılık analizi yapılmış ve heyelan duyarlılık haritaları üretilmiştir. Heyelan duyarlılık analizi için Coğrafi Bilgi Sistemleri (CBS) platformlarından ArcGIS for Desktop kullanılmıştır. Kamu kuruluşları ve açık erişimli çevrimiçi kaynaklardan coğrafi veriler temin edilmiştir. Çeşitli CBS araçları ile veriler çalışma alanına ve amacına göre mekânsal olarak düzenlenmiştir. Literatür araştırması sonucunda Heyelan duyarlılığı için eğim, eğim şekli, litoloji, yağış, bakı, topoğrafik nemlilik indeksi (TNI), akarsulara, karayollarına, fay hatlarına uzaklık, arazi kullanımı, toprak, yükseklik ve normalize edilmiş fark bitki örtüsü indeksi (NDVI) olmak üzere toplam 13 kriterin etkili olduğu belirlenmiştir. AHS yöntemi kullanılarak her bir kriterin heyelan oluşumundaki etkilerinin önem dereceleri ile kriterler arası ağırlıkların belirlenmesi için ikili karşılaştırmalar yapılmış ve üst üste çakıştırma yapılarak AHS yöntemine göre heyelan duyarlılık haritası üretilmiştir. Ayrıca AFAD ve MTA’dan temin edilen heyelan envanter kayıtlarından yararlanılarak heyelan meydana gelen sahaların tüm çalışma sahasındaki etkisi göz önünde bulundurularak FR yöntemine göre heyelan duyarlılık haritası üretilmiştir. Her iki yöntemde üretilen haritalar karşılaştırıldığında, çalışma sahasında gözlenen heyelanların yerlerini belirleme açısından FR yönteminin AHS yöntemine göre daha gerçekçi sonuçlar ortaya koyduğu tespit edilmiştir.

Authors: Kyienko Z. B. , Kimeichuk I. V. , Matskevych V. V.
Published: January 2023

Purpose. Analysis of plant micropropagation technologies for the creation of viable interspecific hybrids and varieties of Actinidia Lindl.
Methods. General scientific – hypothesis, experiment, observation, analysis, synthesis method for drawing conclusions.
Results. The introduction of in vitro technologies is now becoming the dominant commercial method of large-scale and rapid production of seedlings with stable inheritance of variety traits, high multiplication rate, preservation of economically valuable traits in the absence of production seasonality and time constraints. In addition to reproduction, the breeding process is also accelerated, including mutagenesis and hybridization. It is important to obtain not only a sterile explant, but also a morphogenically active one, that is, a plant that takes roots and subsequently regenerates in vitro. The best in terms of decontamination efficiency is the method of treatment with hypochlorite and the addition of PPM biocide to the nutrient medium, but under these conditions, the lowest survival of explants in all samples was noted. The efficiency of introduction into aseptic culture at the first stage of micropropagation is also affected by the biological characteristics of the primary explants. In studies with nutrient media for A. arguta, it was found that of the elements of mineral nutrition, only 11 ions are necessary for life: five macro- (N, K, P, Mg, S) and six microelements (Cl, Fe, B, Mo, Na, I). Plants in vitro have a lower dry matter content and a greater amount of moisture, including free moisture, which is quickly lost when the water balance is disturbed.
Conclusions. The abi­lity to regenerate is more pronounced in the species A. chinensis and A. deliciosa, and to a lesser extent in A. arguta. For A. chinensis, the use of hydroponic technology for the adaptation of regenerants at the ex vitro stage is effective.
Inheritance of kernel number per spike in F1 of spring barley obtained from crossings of cultivars of different origin, purpose of use and botanical varieties
Authors: Polishchuk T. P. , Hudzenko V. M.
Published: January 2023

Purpose. To reveal the peculiarities of inheritance of kernel number per spike in crosses of spring barley cultivars of different origin, purpose of use and botanical varieties, as well as to distinguish effective genetic sources for impro­ving the trait.
Methods. The study was carried out at the M. Remeslo Myronivka Institute of Wheat of National Academy of Agrarian Sciences of Ukraine in 2019 and 2020. In F1 of spring barley in two diallel crossing schemes the degree of phenotypic dominance, parameters of genetic variation, and combining ability for kernel number per spike were determined. Results. According to the indicator of the degree of phenotypic dominance, all possible types of inheritance of kernel number per spike were identified. In a number of crossing compositions, a change in the type of inheritance depending on the conditions of the year was revealed. Most combinations with overdominance in both years were noted in crossings of the covered awned cultivar ‘Avgur’, as well as the covered awnless cultivar ‘Kozyr’. According to the parameters of genetic variation in crosses of malting varieties (covered awned), correspondence of the additive-dominant model, overdominance and dominance in loci, as well as unidirectional dominance to increasing of the trait caused by dominant effects were revealed. When crossing cultivars of different varieties, a change in gene action in different years was found. In particular, additive-dominant system changed to complementary epistasis, incomplete dominance to overdominance, unidirectional dominance to increa­sing of the trait to multidirectional dominance. The genetic sources of increased general combining ability were identified, as follows: covered awned malting cultivars ‘Quench’ and ‘Avgur’, the naked awned cultivar ‘CDC Rattan’, as well as the covered awnless cultivar ‘Kozyr’. Based on the constants of specific combining ability, the most promising crossing combinations for further breeding efforts were determined.
Conclusions. The identified peculiarities of the inheritance of kernel number per spike make it possible to optimally combine parental components of crossings and carry out directional selection to increase the trait when developing spring barley cultivars for different use and different botanical varieties.

Published: January 2023

Pharmaceuticals have been continuously detected from surface water and groundwater. In order to improve the rejection performance of pharmaceuticals by a nanofiltration membrane (NF), a positively charged membrane was prepared by co-deposition of natural gallic acid and polyethyleneimine on the polyacrylonitrile hydrolysis membrane. Effects of gallic acid concentration, polyethylene imine concentration, reaction time, and the molecular weight of polyethylene imine were documented. The physical and chemical properties of the membrane were also investigated by surface morphology, hydrophilicity, surface charge, and molecular weight cut-off. The optimized membrane had a molecular weight cut-off of about 958 Da and possessed a pure water permeability of 74.21 L·m−2·h−1·MPa−1. The results exhibited salt rejection in the following order: MgCl2 > CaCl2 > MgSO4 > Na2CO3 > NaCl > Na2SO4, while the rejection ability of pharmaceuticals is as follows: amlodipine > atenolol > carbamazepine > ibuprofen, suggesting that the positively charged membrane has enhanced retention to both divalent cations and charged pharmaceuticals. In addition, the antibacterial membrane was obtained by loading silver nanoparticles onto the positively charged membrane, which greatly improved the antibacterial ability of the membrane.
Targeting Ferroptosis as a New Approach for Radiation Protection and
Mitigation

Published: January 2023

Radiation-induced normal cell toxicity (RINCT) is a major factor to consider while
treating any ailment with radiotherapy. Clinical irradiation of tumors necessitates an understanding
of the potential efficacy of radiation protective agents in reducing radiation damage to healthy
tissues and their effects on tumor tissue radiosensitivity. Ferroptosis is a relatively new form of
iron-dependent cell death that has been linked to a variety of disease pathologies. The key mediators
of ferroptosis have been identified as lipid peroxidation and iron metabolism. Lipid peroxidation
is the result of a reaction between reactive oxygen (ROS) and reactive nitrogen species (RNS)
with phosphatidylethanolamine-containing polyunsaturated fatty acids (PUFAs). Ferroptosis inhibitors
have been demonstrated to have anti-inflammatory effects in animal models of disease. It
was recently shown that ionizing radiation (IR) generates severe ferroptosis, a critical component
of RT-mediated normal cell toxicity. These findings support the use of ferroptosis inhibitor treatments
for the treatment of radiation normal cell toxicity. Targeting lipid metabolic substrates and
controlling ferroptosis by radiation could reduce toxicity and improve clinical outcomes. In this
study, we address the relationships between radiotherapy and various types of radiation-induced
cell death, and we discuss the interactions between ferroptosis and other kinds of controlled cell
death generated by radiotherapy, and we investigate combination treatment options targeting ferroptosis
in radiotherapy. This review will be a foundation for future research on ferroptosis in radiotherapy.
Additionally, the relevant patents on ferroptosis inhibitors with various therapeutic
potentials have been discussed.

Principles of bioethics in the treatment and rehabilitation of patients with chronic kidney disease
Authors: Denova L.D.
Published: January 2023

Chronic kidney disease has a major impact on global health, causing both morbidity and mortality worldwide. Bioethics (from Greek: βιοσ — life, ετηοσ — custom) is a science that analyzes and studies the morality of human actions in the field of health care and in the biological and medical fields in accordance with its moral standards and values. The modern concept of bioethics is closely intertwined with the concepts of deontology, doctor’s code of ethics in the medical practice of a nephrologist. In the medical practice, there is a tendency to spread of absolutization of drug therapy, fetishization of laboratory, instrumental, hardware research methods, medical aggression. The patient’s contact with the doctor should begin with a conversation. On the part of the doctor, such a conversation should be based on the principles of empathy. The doctor must be able to dispel passivity and depression of patients, to strengthen social contact, and expand the space of their intellectual interests. The behavior of the doctor, who demonstrates a lack of understanding of the patient’s problems and does not consider psychosocial relationships, often causes mistrust and even becomes the cause of a conflict between the doctor and the patient. Issues of medical ethics in case of the need for kidney replacement therapy remain difficult. The offer of peritoneal dialysis, hemodialysis can be perceived positively from the first word, or it can be categorically negative, depending on the character and emotional state of the patient. The purpose of our article is to consider the peculiarities of the implementation of bioethical principles in the treatment and rehabilitation of patients with chronic kidney disease. The object of the work was the articles of philosophers, doctors, and lawyers who studied ethical relations in the medical environment in general and nephrology in particular. The subject of the study was the ethical norms and rules fixed in the documents. The article uses methods of historical approach, research of historical documents.

Authors: Thanasas Georgios L. , Slimistinou Aikaterini , Kontogeorga Georgia , Lampropoulos Spyridon
Published: January 2023

Before the early negative effects of human activity on the environment and nature became apparent, there was no particular concern. The consequences of exponential population growth over the years brought a negative impact, increasing the risk and concern for the future. In recent decades, there has been an admittedly large, joint, and ambitious effort at the international and European levels to promote and implement the values and rules of green development and growth. Green growth is crucial regarding the policy implemented by the European Union (EU). Therefore, it calls on all its member states to participate in this effort concerning the environment and natural resources, having as its main tool environmental taxation. This paper primarily aims in proving that environmental taxation facilitates, through the proper implementation of European Union rules, the achievement of green growth. The research methodology followed, was the study of the environmental indexes of the European Union countries from 2002 to 2020, including Greece. They were analyzed and compared to the European Union average indexes (Eurostat, 2020). The study results highlighted that environmental taxation is crucial in enhancing green growth by increasing the revenues of state funds and reducing environmental problems at European and international levels.

Published: January 2023

En la actualidad, los programas de formación de docentes están llamados a reflexionar de manera imperativa sobre la pertinencia del currículo y las prácticas pedagógicas de sus docentes en torno al desarrollo de competencias digitales, según los desafíos de la sociedad del conocimiento. En este contexto, el presente artículo de investigación pretende como objetivo determinar las dimensiones que promueven el desarrollo de las competencias digitales de los docentes en formación inicial. Corresponde a un estudio de campo, de tipo cuantitativo, realizado con un método de análisis descriptivo, que aplica como instrumento el cuestionario y el análisis factorial para determinar las variables. Los resultados se describen a partir de cuatro dimensiones que clasifican las competencias digitales: apropiación de las TIC (D1), metodología educativa a través de las TIC (D2), formación del profesorado en TIC (D3) y actitud ante las TIC (D4). Los resultados relacionan las dimensiones que enmarcan la sociedad del conocimiento y el nivel de competencia digital de los docentes en formación. Se aprecian de manera significativa los factores que evalúan la actitud favorable frente a las TIC y el compromiso para el desarrollo de buenas prácticas con la integración de la tecnología. Sin embargo, el colectivo de docentes expresa dificultades frente a los factores que se relacionan con la planeación e implementación metodológica de la evaluación con TIC, porque requieren de la articulación de la disciplina que enseñan con la aplicación de recursos TIC, lo cual transforma la práctica centrada en contenidos hacia prácticas que promueven la innovación y la formación en competencias.
Prueba por inteligencia artificial

Published: January 2023

El presente artículo propone reglas probatorias para la producción de la prueba por inteligencia artificial dentro del proceso judicial colombiano a partir del dictamen pericial científico. Para ello se elaboró una metodología cualitativa, jurídica, descriptiva y propositiva; de diseño bibliográfico-documental basado en fichas de análisis de fuentes segundarias (antecedentes, normativa y jurisprudencia) estudiadas desde la hermenéutica sistemática y teleológica. Se cuestionó la eficacia de los mensajes de datos frente a las necesidades de la prueba derivada de la máquina sapiente, se identificaron los elementos dogmáticos del dictamen pericial en Colombia a partir de los múltiples regímenes procesales y se caracterizó a la pericia científica según la ley 721 de 2001. Resultó que la normativa actual exige que la producción del porcentaje probabilístico derivado de la inteligencia artificial sea mediante un documento por mensaje de datos. A su vez, el fenómeno de la caja negra limita la valoración del juzgador, ya que no tiene certeza del fundamento teórico aplicado a la casuística en particular. No obstante, la estructura de la pericia científica permite que sea un experto en el tema quien garantice la cadena de custodia de la partícula digital y explique el funcionamiento de los algoritmos inteligentes y su aplicabilidad en el caso litigioso. Lo que garantiza que la contraparte ejerza su defensa práctica y el juzgador pueda aprehender brevemente los conocimientos tecnológicos y científicos mínimos para examinar la realidad fáctica que la prueba pretende evidenciar.

Background: Allergy health problems worldwide are mainly caused
by allergens from domestic cats ( Felis catus). Fel d 1 is a
major allergen that causes severe allergic reactions in humans,
including rhinitis, conjunctivitis, and life-threatening asthma.out
cats. Fel d 1 level in CH2 knockout cats was assessed by enzyme-linked
immunosorbent assay (ELISA). Cytoplasm injection clone technology (CICT)
was used to clone the CH2 knockout cat. Results: We report the
first successful generation and cloning of CH2 knockout cats using the
CRISPR-Cas9 system and CICT. CH2 knockout cats were confirmed using T7E1
and Sanger sequencing. Cloned CH2 knockout cat was verified by
microsatellite analysis. Remarkably, ELISA proved that Fel d 1 level of
CH2 knockout cats was extremely low compared with that of wild type
domestic cats. Conclusion: CH2 knockout cats we generated
showed an extremely low level of Fel d 1 and could be hypoallergenic
cats. Our study indicates that creating hypoallergenic cats using the
CRISPR-Cas9 system is a significant step forward in the consequence that
these cats can safely approach allergic patients.
How should diverse stakeholder interests shape evaluations of complex water resources systems robustness when confronting deeply uncertain changes?

Published: January 2023

Robustness analysis can support long-term planning, design and operation
of large-scale water infrastructure projects confronting deeply
uncertain futures. Diverse actors, contextual specificities, sectoral
interests, and risk attitudes make it difficult to identify an
acceptable and appropriate robustness metric to rank decision
alternatives under deep uncertainty. Here, we contribute an exploratory
framework to demonstrate how methodological choices affect robustness
evaluation. The framework is applied to a multi-actor, multi-sector
Inchampalli-Nagarjuna Sagar (INS) water transfer megaproject in Southern
India. We evaluate a suite of dynamic adaptive water transfer strategies
discovered using evolutionary multi-objective direct policy search
(EMODPS), a status quo strategy of no water transfer, and a strategy
proposed by regional authorities. We evaluate robustness across
wide-ranging scenarios that capture key uncertainties in potential
future changes in reservoir inflows and water demands in the basins.
Results show that the priorities of different actors, sectoral
perspectives, and risk attitude significantly affect robustness rankings
of strategies. We found that compromise strategies obtained from EMODPS
are better able to balance the diverse performance requirements across
various actors and sectors when compared to the no-transfer and proposed
transfer. We reveal a key robustness tradeoff between the donor basin’s
ecological requirements and the recipient basin’s socio-economic
requirements. While robustness analysis is central to water
infrastructure planning, we show why exploratory robustness analyses
that engage with conflicting stakeholder objectives is vital for
long-term sustainability. Furthermore, the selection of compromise
solutions should be guided by an explicit understanding of how assumed
risk attitudes shape stakeholders’ understanding of consequential
vulnerabilities.

Organic agricultural waste is successfully used in the production of mushrooms as it promotes the reuse of resources and increases food production. For the formulation of the substrate for Pleurotus spp. production, the availability of nutrients must be rigorously analyzed to assess whether supplementation is necessary. The aim of this paper was to evaluate the agronomic behavior of Pleurotus ostreatus var. Florida when grown on different straws and to analyze nutrient dynamics at the beginning and end of cultivation. Straws of rice, wheat and brachiaria were used as substrates without any supplementation. The yields, biological efficiency, number and weights of mushrooms were evaluated in two crop cycles. Rice straw provided a higher yield, better biological efficiency and a greater number of mushrooms in both cultures. Wheat straw showed intermediate results for the same variables. None of the substrates showed a significant difference for mushroom weight. In the first crop, only Mg and the number of mushrooms exhibited a positive correlation; in the second crop, only K and the yield of the 1st flush showed a positive correlation. With this study, it was possible to demonstrate that agricultural residues with higher levels of K increase P. ostreatus yield, and that Mg management affects the number of mushrooms for harvesting. The results will be a useful guide for efficient and sustainable mineral supplementation of the substrate.
Preserving and dissemination of digitised sound heritage in contemporary times: The potential of blockchain technology
Authors: Stojanovic Dragana
Published: January 2023

Following recent technological changes, the archival profession will reach
the moment of surpassing previously dominant mediaspheres, in which sounds
and images were stored in traditionally located archives. This is not to say
that tradi?tional archives are not needed anymore - on the contrary. In this
article, I will try to bring out the possibilities of upgrading traditional
archives with the help of blockchain technology and to analyse the complex
navigation between online market and commodification in the world of
contemporary ethnomusicological contribution to sound heritage archiving.
Under political and market pressures: The staging of operetta in interwar Belgrade
Authors: Vesic Ivana
Published: January 2023

In this paper, I will focus on the reconstruction of the history of operetta
companies established in interwar Belgrade. I gave priority to those
ensembles that held regular performances for a longer period of time in the
late 1920s and late 1930s. Aside from making a detailed overview of several
more stable operetta theatres in Belgrade at the time, including their
repertoire and leading artists, the attention will also be paid to
uncovering the broader context of their work. The issues of state cultural
policy and the rise of competitiveness inside the local spheres of culture
and entertainment will also be discussed.
Victor Hugo’s verses and interpretation of Ivo Andric’s novel The Journey of Alija Djerzelez
Authors: Aleksic Milan
Published: January 2023

The paper is dedicated to the analysis of Ivo Andric?s novel The journey of
Alija Djerzelez and its connection with the verses of Victor Hugo written by
Ivo Andric on the cover of the incomplete manuscript of the third part of
the novel that is been kept in Archives of Serbian Academy of Science and
Arts. Through analysis, we show that in this novel that has been printed for
the first time complete, in Belgrade 1920, Ivo Andric began to depict
literary heroes who commit evil deeds, which was left aside in
interpretations of this novel for a long time, since this layer of meaning
remained in the shadows due to the effect of the grotesque and the presence
of comedy. Alija Djerzelez is actually the first in a series of evil-doer in
Andric?s fictional worlds and the first literary hero on whom Andric began
writing about the influence of evil on human beings.
Two Milos and one Migrations
Authors: Ruzic Dobroslav
Published: January 2023

After interesting conversations with his uncle Milos Crnjanski, who explained
to him on one occasion that when writing Migrations (?????) he also used
data from the memories of the author?s grandfather and great-grandfather,
the author embarked on a careful reading of the memories and found in them
details that confirmed what Milos had stated. The author has prepared a
presentation in which excerpts from Memoirs are presented against the quotes
from the Migrations.

In this work, the multi-walled carbon nanotubes (MWCNTs) were purified with
an acid treatment and subsequently dispersed using ultrasound and a nonionic
surfactant solution of ethoxylated lauric alcohol 7 moles of ethylene oxide
(E7E). Then, carbon nanotubes (CNTs) were used as a reinforcement phase (0.4
wt.% and 0.8 wt.%) in the Al- 10Mg alloy. The high-energy ball milling was
employed for the nanocomposites processing, and the resulting powders
consolidate by uniaxial pressure. Measurements of Vickers microhardness,
nanohardness, displacement, and Young's modulus were carried out on the
compacts. The samples were analyzed using scanning electron microscopy
(SEM), X-ray diffraction (XRD), ultraviolet-visible spectroscopy (UV-Vis),
Fourier-transform infrared spectroscopy (FT-IR), and Raman spectroscopy
(RS). Good dispersion of MWCNTs was achieved using 0.5 mg/ml of the E7E
surfactant. The CNTs were dispersed in the Al-10Mg matrix using 0.25 h of
milling. After powders compaction, the Al-10Mg/0.4MWCNTs nanocomposite
presented a microhardness of 190 HV, nanohardness of 3.5 GPa, and Young's
modulus 116 GPa.
Fabrication of an al2o3-1% ti composite with some characteristics of a biomaterial

Published: January 2023

An Al2O3-1 wt.% Ti composite was prepared by powder techniques with the
intention of analyzing its mechanical and chemical properties for its
possible application as a biomaterial. Alumina was synthesized using the
reaction bonding aluminum oxide (RBAO) process. The powders resulting from
the milling stage present sizes minor than 1.5 microns. With the help of
X-ray diffraction and differential thermal analysis, it was determined that
aluminum oxidizes in both solid and liquid states during the RBAO process.
It was also found that the alumina formation reaction in this process is
completed at 1,100oC. From the measurements of mechanical properties (HV,
KIC, E) in the Al2O3-1 wt.% Ti composite, it was determined that these
properties are better than the same properties of compact bone.
Electrochemical impedance spectroscopy, indicates that additions of 1 wt.%
Ti on Al2O3 enhance its corrosion resistance. The bioactivation of a Al2O3-1
wt.% Ti composite was successful using a biomimetic method, because after 21
days, hydroxyapatite begins to proliferate on the surface of the substrate.
With all these results it can be commented that it is feasible to use
Al2O3-1 wt.% Ti composite in the elaboration of synthetic bone for its
application as a biomaterial.

It is very important to determine microstructure parameters of consolidated
ceramic samples, because it opens new frontiers for further microelectronics
miniaturization and integrations. Therefore, controlling, predicting and
designing the ceramic materials? properties are the objectives in ceramic
materials consolidating process, within the science of sintering. In order
to calculate the precise values of desired microstructure parameter at the
level of the grains? coating layers based on the measurements on the bulk
samples, we applied the artificial neural networks, as a powerful
mathematical tool for mapping input-output data. Input signals are
propagated forward, as well as the adjustable coefficients that contribute
the calculated output signal, denoted as error, which is propagated
backwards and replaced by examined parameter. In our previous research, we
used neural networks to calculate different electrophysical parameters at
the nano level of the grain boundary, like relative capacitance, breakdown
voltage or tangent loss, and now we extend the research on sintered
material?s density calculation. Errors on the network output were
substituted by different consolidated samples density values measured on the
bulk, thus enabling the calculation of precise material?s density values
between the layers. We performed the neural network theoretical experiments
for different number of neurons in hidden layers, according to experimental
ceramics material?s density of ?=5.4x103[kg/m3], but it opens the
possibility for neural networks application within other density values, as
well.
