Authors: Wu Liang , Xiao Yifeng , Xia Xiuyan , Qian Jinwen , He Yuehui
Published: March 2020

The oxidation behavior of porous Ni-Cr-Fe materials prepared by reactive powder synthesis with different open porosity was studied in air at 6008C, 800 8C and 1 0008C. The differences in surface morphology, phase and pore structure parameters between material oxidized and non-oxidized were characterized by means of scanning electron microscopy, X-ray diffraction analysis and mercury intrusion. The results show that the oxidation rate of the samples which were oxidized at 600 8C for 340 h, for 560 h at 800 8C and for 560 h at 1 000 8C were 0.00027%2 h-1, 0.0558%2 h-1, and 0.64412%2 h-1, respectively. All the oxidation kinetics curves obeyed the parabolic law, exhibiting excellent high temperature oxidation resistance.

Published: March 2020

A new nanocrystalline Fe71B23Nb6 alloy powder was prepared by mechanical alloying. The phase transformation and morphological and microstructural properties of the as-prepared alloy were investigated by scanning electron microscopy, laser granulometry, and X-ray diffraction with respect to the milling time (0- 200 h). During the milling process, it was observed that the dissolution of Nb and B atoms into the Fe matrix formed solid solutions of Fe (Nb), Fe (B), Fe23B6, Fe2B, and Fe (Nb, B). Moreover, the insertion of B atoms into the Nb network generated the Nb (B) phase. Furthermore, the minimum crystallite size was measured as approximately 1 nanometer. In addition, the dislocation density gradually increased with the extension of the milling time, and the crystallization of the partially amorphous phase occurred after 200 h of milling.
Phase transformations during the oxidation of fayalite in iron-rich nickel slag
Authors: Du Xueyan , Ma Yongbo
Published: March 2020

Phase transformations during the oxidation of fayalite (Fe2SiO4) are investigated for the recovery of iron from iron-rich nickel slag by oxidation-magnetic separation. The proportions of various phases calculated by FactSage 7.1 show that augite and spinel are the major phases in the FeO-SiO2-MgO-CaO-O2 system in air atmosphere. The decreased content of Fe2+shows that Fe2SiO4 is gradually oxidized into Fe3O4 with increasing oxidation time. XRD patterns demonstrate that Fe3O4and Ca(Mg,Fe)Si2O6 are the dominant phases after the oxidation. The Mössbauer spectrum indicates that 93.1 wt.% of iron in oxidized nickel slag is in magnetic minerals, while a limited amount of iron is contained in non-magnetic minerals. Ca(Mg,Fe)Si2O6 was formed during the heating stage in Ar atmosphere through the polymerization of SiO4
4-and also via peritectic reaction after the isothermal oxidation.

Published: March 2020

High-strength 690-MPa steel was prepared using a wire + arc additive manufacturing (WAAM) technology. The phase composition, microstructure, and crystal structure of highstrength 690-MPa steel samples were analysed, and the results show that a sample prepared using WAAM technology achieves a good formation quality. The metallographic structure was mainly acicular ferrite, massive ferrite, and granular bainite. The microhardness distribution of the vertical and horizontal sections of the samples is uniform. Excellent mechanical properties of the specimen were shown, including a horizontal yield strength of 536 MPa, a tensile strength of 760 MPa, an elongation of 23.5%, a Charpy impact value of 70 J at -508C, a vertical yield strength of 486 MPa, a tensile strength of 758 MPa, an elongation of 21.5%, and a Charpy impact value of 51 J at -508C.
Effects of Gd on the microstructure and mechanical properties of Mg–Li dual-phase alloys
Authors: Zhang Na , Dong Hanwu , Wang Limin , Cheng Renju , Zhan Jun , Chen Xianhua , Jiang Bin , Pan Fusheng
Published: March 2020

Gadolinium (Gd) (up to 10 wt.%) was added to Mg-7Li dual-phase alloys, and the Gd-containing alloys were heat-treated for 3 h at 698 -748 K. The microstructure and mechanical properties of the as-cast and heat-treated alloys were then examined. The results indicated that the addition of Gd introduced the Mg3Gd phase into the duplex Mg-7Li alloy, containing a-Mg and b-Li phases. Gd also refined the grains, and the addition of 8 wt.% Gd resulted in the highest grain refining effect. The Gd atoms in the a-Mg phase, as well as precipitates in b-Li matrixes and at the surface of the a-Mg phase, strengthened the alloys. The highest strength alloy was obtained after the addition of 6 wt.% Gd, with tensile and compressive yield strengths of 143- 147 MPa, about twice as those of the Mg-7Li alloy. Heat treatment, which was found to be optimum at 723 K for 3 h, can decrease both the amount of precipitate and the hardness of the alloy, but not the amount of the Mg3Gd phase.

Authors: Usenko Natalia , Ivanov Michael , Kotova Natalia
Published: March 2020

The enthalpies of mixing in liquid alloys of the binary Cu-Eu and ternary Al-Cu-Eu systems were determined over a wide range of compositions by means of isoperibolic calorimetry in the temperature range 1 300 - 1450 K. The enthalpies of mixing in the Cu-Eu system demonstrate small exothermic effects (ΔHmin = -4.1 ± 0.5 kJ · mol-1at xCu = 0.70). The measurements for the liquid ternary Al- Cu-Eu alloys were performed along five sections (xCu/ xEu = 0.70/0.30; 0.50/0.50 and 0.27/0.73 for xAl changed from 0 up to 0.30 and xAl/xEu = 0.20/0.80 and 0.47/0.53 for xCu changed from 0 up to 0.30). The enthalpies of mixing in the ternary system were found to be exothermic and increasing in absolute values from the Al corner towards the Al0.40Cu0.60-Al0.60Eu0.40section and from the constituent binary Cu-Eu system towards the same section. The minimum value of the integral enthalpy of mixing is expected in the vicinity of the Al0.6Eu0.4composition of the binary constituent Al-Eu system (about -23.00 kJ · mol-1).

Argumenty Walentego Barczewskiego świadczące o polskości południowej Warmii w drugiej połowie XIX wieku (na podstawie utworu “Kiermasy na Warmii” )
Authors: Biolik Maria
Published: March 2020

W  artykule przedstawiono argumenty księdza W. Barczewskiego (1856-1928) świadczące o polskości Warmii,   która od pokoju toruńskiego 1446 aż do pierwszego rozbioru Polski w 1772 była częścią królestwa polskiego. Warmia w wyniku rozbiorów Polski została włączona do Niemiec. Podstawą artykułu jest utwór „Kiermasy na Warmii” napisany przez W. Barczewskiego,   wydany po raz pierwszy w 1883 roku, pod nazwą „O kiermasach na polskiej Warmii.  Analizowany w artykule materiał został wypisany z utworu W. Barczewskiego „Kiermasy na Warmii” wydanego w 1984 roku, oraz z wydania w 1923 r.. 

Poszukując w utworze W. Barczewskiego dowodów świadczących o polskości Warmii zwrócono  uwagę na wypowiedzenia i wyrażenia zawierające formy gramatyczne leksemów Polska, polski, polszczyć, polszczyzna, polskość, polsko-wiarmijski, po polsku, polskie nazwy miejscowe i osobowe.  Z tekstu wypisano zdania zawierające te leksemy i podzieliłam je  ze względu na zawartą w nim tematykę. Pozwoliło to wyodrębnić takie argumenty świadczące o polskości jak:  związki historyczne i osadnicze z Polską, właściwe Polakom przywiązanie do religii katolickiej, zachowanie polskiej gwary, gościnność mieszkańców i polskie obyczaje kulturowe zakodowane w języku. 

W drugiej połowie XIX wieku nasiliły się na terenie południowej Warmii antagonizmy narodowościowe, a jednocześnie zaczęło kształtować się poczucie odrębności polskich mieszkańców Warmii od katolickiej ludności niemieckiej i Mazurów.   Znalazło to wyraz  w utworze W. Barczewskiego.

„Parlando“ in der geschriebenen Wissenschaftssprache?
Authors: Olszewska Danuta
Published: March 2020

Przedmiotem artykułu są struktury organizujące pisane teksty naukowe, w obrębie których obserwuje się wyraźną konkurencję między stylem formalnym a stylem nieformalnym. Rezultatem tej konkurencji jest hybrydyzacja gatunków tekstowych i zjawisko tzw. "parlando”, które – przeniesione z dziedziny muzykologii – oznacza pisanie zbliżone do mówienia. Fenomen ten pokazany jest w artykule na przykładzie rozprawy naukowej, a ściślej mówiąc na przykładzie pracy doktorskiej jako gatunku tekstowego, typowego dla domeny nauki. Ważne było bowiem pytanie, jak młodzi autorzy podchodzą dzisiaj do jednej z podstawowych cech stylu naukowego, a mianowicie obiektywizacji przekazywanych treści. Uwzględnione zostały przy tym teksty niemieckie i polskie z zakresu nauk humanistycznych, w których obserwuje się podobne tendencje stylistyczne na płaszczyźnie metakomunikacyjnej. Głównym celem badania jest uchwycenie wyróżników zjawiska „parlando”, wskazanie na jego przyczyny i określenie jego skutków dla stylistycznego kształtu współczesnych tekstów naukowych.

Is blending a godsend or a curse? An attempt at the theory’s assessment from the cognitive linguistic perspective
Authors: Jabłońska-Hood Joanna
Published: March 2020

Niniejszy artykuł jest próbą ewaluacji, stworzonej przez Gillesa Fauconniera oraz Marka Turnera (2002), teorii integracji pojęciowej, zwanej również teorią amalgamatów. Koncepcja ta wykorzystywana jest w badaniach z zakresu wielu dyscyplin naukowych, m.in.: językoznawstwa, literaturoznawstwa czy prawa. Obok licznych zwolenników teorii amalgamatów istnieje spore grono krytyków, zarzucających jej m.in. zbytnie uogólnianie zasad czy też zbyt szerokie zastosowanie w znacznie różniących się od siebie dziedzinach. W swoim artykule pragnę zaprezentować najważniejsze głosy krytyczne wysuwane wobec teorii amalgamatów oraz zastosowaną w nich kontrargumentację. Ponadto chciałabym także przedstawić możliwe kierunki rozwoju dla omawianej koncepcji z perspektywy językoznawstwa kognitywnego oraz zaprezentować kilka propozycji jej udoskonalenia.

Avaliação comparativa da exatidão de termômetros digitais do tipo “espeto” para utilização em ensaios e atividades de pesquisa
Authors: Margarido GN , Tchernov DP
Published: March 2020

O presente trabalho mostra uma avaliação de uma comparação do erro sistemático (ou desvio), e da repetibilidade apresentados por cinco termômetros digitais idênticos, de mesmo modelo, marca, fabricante e sem uso anterior a realização desse trabalho. Os resultados são obtidos a partir de comparações entre os valores obtidos desses termômetros estudados aos valores obtidos de um termômetro padrão, devidamente calibrado e com erros e incertezas conhecidos, utilizado como referência em uma mesma medição. Os resultados obtidos no trabalho mostram que os instrumentos digitais de medição de temperatura apresentam limitações quanto à exatidão, mesmo quando são utilizados instrumentos novos e idênticos, e da necessidade de se conhecê-la previamente antes da utilização desses instrumentos através da calibração dos mesmos.

Published: March 2020

Este trabalho apresenta o desenvolvimento de um controlador de velocidade (RPM) para motor de Corrente Contínua (DC, da sigla em inglês) utilizando técnicas de Controle de Processos e funções do LabVIEW® (National Instruments, EUA). Um sistema atuando em malha fechada possibilita uma resposta eficaz do controlador aos distúrbios pelas perturbações e ruídos dos sinais externos a planta, pois o controlador monitora e executa atuações de reação em tempo real aos fenômenos físicos previamente convertidos em pulsos elétricos digitais ou analógicos por meio de transdutores, desta forma mantendo o sistema estabilizado na aplicação da variável controlada independente do ambiente externo nas condições de contorno especificadas, garantindo assim a homogeneidade inerentes em aplicações industriais, assim como resguardando o sistema de eventuais problemas técnicos. O controlador foi desenvolvido por meio de linguagem gráfica no LabVIEW, o atuador é um módulo de ponte H L298N (STMicroelectronics, Suiça) que varia a tensão de saída proporcionalmente a porcentagem de Duty Circle PMW da Entrada Enable, o L298N foi acoplado eletricamente a um motor EC 353518 (Maxon, Suiça) que varia a velocidade (RPM) linearmente à tensão fornecida pelo L298N e o transdutor é um sensor encoder rotacional KY-040 (Keyes, EUA), que converte a rotação do rotor do motor em pulsos elétricos digitais, podendo assim calcular a velocidade do motor por uma quantidade exata de pulsos. A leitura da velocidade do motor foi satisfatória e o controle PI da velocidade apresentou erro em regime estacionário menor que 2%.
The Effect of Hydroelectricity Consumption on Environmental Degradation – The Case of South America region
Authors: Koengkan Matheus , Losekann Luciano Dias , Fuinhas José Alberto , Marques António Cardoso
Published: March 2020

This article analyses the impact of hydroelectricity consumption on environmental degradation (CO2 emissions) in seven South American countries, in a period from 1966 to 2015. The Unrestricted Error Correction Model (UECM) form of the Auto-regressive Distributive Lag (ARDL) was utilized. The initial tests prove the presence of heteroskedasticity, cross sectional independence, and first-order autocorrelation. The results show that the consumption of hydroelectricity causes a reduction of -0.0465 in environmental degradation in the short run, and increase 0.0593 in the long-run. This empirical evidence could encourage the creation of new policies, which introduce new energy technologies that release zero carbon in the energy matrix.
The Influence of Competency, Independency, and Professionalism on Audit Quality
Authors: Kartika Dewi , Pramuka Bambang Agus
Published: March 2020

The purpose of this research is to examine the influence of competency, independency, and professionalism on audit quality. Competency, independency, and professionalism are three characteristics of a competent auditor. The population of this research is the auditor of accounting firms in Central Java. The samples of this research are employees of auditors working at accounting firm (KAP) Budiman, Wawan, Pamudji Tegal, KAP Wartono & Fellow Surakarta, KAP Sophian Wongsaro Semarang, KAP Heliantono & Semarang Branch.  Forty-five questionnaires are employed in this study. Before the hypotheses testing, validity and reliability tests are run to determine the validity and reliability of the data. Hypothesis testing techniques uses regression analysis. These research results show that competency, independency, professionalism influence the quality of the audit. However, these results have to be cautiously interpreted since only few auditors’ questionnaires were worth analyzing. Future studies may increase the number of KAPs from other districts in Indonesia or using not only auditors from accounting firms but also government auditors or internal auditors.
The Association between Locus of Control and Job Satisfaction to Auditor Ethical Sensitivity
Authors: Gunawan Adi , Munari Munari
Published: March 2020

This study aims to analyze the association between locus of control and job satisfaction to auditor ethical sensitivity. The association between locus of control and ethical sensitivity is based on the notion that auditors with an internal locus of control likely have a high ethical sensitivity. The association between job satisfaction has emerged from the understanding that auditors who are satisfied with their jobs tend to have keen ethical sensitivity. The population of this study is 300 government auditors at the office of Financial and Development supervisory agency (BPKP) in East Java. The sampling technique is simple random sampling, which includes a minimum number of sample of 30 auditors. The type of data is primary data gathered from distributed questionnaires. Rank Spearman correlation test is used to determine the association between the variables. This research found that locus of control is related to auditor ethical sensitivity. It implies that internal locus of control can influence the auditors' decision-making when faced with an ethical dilemma. On the other hand, job satisfaction does not associate with auditor ethical sensitivity.
Particles in finite and infinite one-dimensional periodic chains
Authors: Ginzburg I F
Published: March 2020

Particle motion in one-dimensional crystal chains is studied with the help of the transfer matrix method. The transition from a finite to an infinite chain is analyzed. In the cases where an analytic solution is impossible, the method allows calculating the energy spectra with reasonable accuracy, based on the known cell potential. It turns out that the structure of allowed and forbidden energy bands arising in an ideal lattice contains some features that are absent in the real world. This means that the model of an ideal lattice should be extended in order to describe reality. We show that accounting for small random perturbations of periodicity may serve as such an extension. Light propagation in a layered medium (including a photonic crystal) is studied using the same method.
Coating Polyurethane with Palmitoleic Acid and Bovine Serum Albumin to Prevent the Host Response to Foreign Materials
Authors: Hussain Sheherbano , Babar Zoha , Hadid Jimmy , McLaughlin Jacqueline
Published: March 2020

Macrophages are cells of the immune system that play a pivotal role in the host inflammatory response by attacking and engulfing any foreign molecule not seen as ‘self.’ They also help regulate the host response by releasing a variety of cytokines and growth factors that act as signals to other cells to amplify the host response. However, the host response causes degradation of implanted medical devices composed of polyurethane as well as other synthetic materials which it does not identify as self. Research was undertaken to investigate the potential of coating polyurethane with the self-like molecules palmitoleic acid and albumin to reduce or prevent the body’s host response from damaging implanted medical devices. Using an in vitro THP-1 bioassay, polyurethane films coated with palmitoleic acid and bovine serum albumin showed a reduction in macrophage adherence. The individually coated palmitoleic acid and bovine serum albumin films significantly reduced the number of cells attached to the films with increasing concentration while the films coated with the conjugate of both showed no statistical difference. This suggests the potential role of self-like molecules in reducing the inflammatory response to foreign materials.

Published: March 2020

The interaction between the human host micro biome and over the counter products has recently been investigated, with surprising results. Some over the counter items may negatively affect the health of the host, supporting the concept of the “hygiene hypothesis”, that is, that disease may be actually caused by the lack of beneficial commensal bacteria. Recent reports on the gluten metabolizing genus, Rothia, and a possible association with Celiac Disease beg the question, what happened to the Rothia? In this study inhibitory factors, such as, Over The Counter oral hygiene products and antagonistic bacteria were investigated and, in vitro, significantly inhibited the gluten metabolizing bacteria, possibly affecting human digestion and contributing to gluten sensitivity.

Authors: Büyükaşık Süleyman , Bozkurt Mehmet Abdussamet , Kapan Selin , Alis Halil
Published: March 2020

Purpose: Constipation is a common entity in society with various factors in the etiology. In this study, we evaluated the role of anal sphincter pressure of patients who refer to surgery clinic with complaint of constipation.Methods: Sixty patients who refer to surgery clinic with complaint of constipation and were diagnosed with constipation due to Rome III criteria between July 2010 and September 2014. These patients were evaluated with defecography and were divided into 2 groups based on presence of rectocele. Both groups’ anal sphincter pressures were evaluated using anal manometry and findings were compared.Results: The patients with rectocele and without rectocele using defecography were inspected with anal manometry regarding resting tone pressure, squeeze pressure, maximum squeeze pressure and simulated defecation response pressure, first sensation volume, urge sensation volume, and maximum tolerable volume. Results were compared and no significant difference was found regarding groups with rectocele and without rectocele (P > 0.05).Conclusion: We have proved the hypothesis arguing that increased sphincter pressures do not play a role in the formation of rectocele by inducing an obstruction and the formation of dilation in proximal bowel, and demonstrated that the presence of rectocele is not dependent on an increase in sphincter pressures.

Problems of deformation of professional legal consciousness in modern Russia (as exemplified in advocacy)
Authors: Grammatikov Valentin V.
Published: March 2020

Purpose: The article aims to establish the causes of deformation of professional legal consciousness. The quality and level of development of legal consciousness of an advocate are determined by the degree of protection of human rights and freedoms, as well as by the state of legality and legal order. In view of the above, the fight against the manifestations of deformation of professional legal consciousness is an accute problem of building a legal and social state. Prevention and elimination of professional deformation of an advocate is impossible without establishing the reasons for its occurrence.

Methods: The author relied on general methods of cognition, as well as such private scientific methods as structural and systemic, functional, comparative and legal, statistical, study of empirical material: disciplinary and law enforcement practices.

Results: Some aspects of the nature of the deformation of legal consciousness of an advocate have been investigated, external and internal factors contributing to its appearance have been revealed, as well as the reasons for the formation of this negative phenomenon of legal reality, which have been implemented by example, including the advocacy.

Conclusions: It is noted that circumstances leading to distortions in the professional legal consciousness affect representatives of the legal community equally or almost equally, but only a smaller proportion of them violate the requirements of legal norms and corporate ethics. A natural question arises as to the reasons why the said "anomalies" of the structure of legal consciousness arise in some cases and not in others. The following conclusion is grounded: the "trigger" of professional deformation of both an advocate and any other person is the degradation of the moral structure of the person - individually formed notions of conscience, shame, justice, the measure allowed and so on.

Authors: Tran Van Huy , Nguyen Phuoc Bao Quan
Published: March 2020

Background: Preliminary studies showed anti HBV nucleoside analogues treatment might improve the histopathology and improve the survival of the cirrhotic patients. Data about efficacy of anti-HBV treatment in Vietnamese cirrhotic patients was still very limited. This study was aimed at assessing the biochemical, virological and the fibrosis responses to Tenofovir disoproxil fumarate (Tenofovir DF) in patients with HBVrelated compensated cirrhosis.
Patients and methods: 48 patients of HBV-related compensated cirrhosis, diagnosed by Acoustic radiation Forced Imaging (ARFI), were enrolled. Tenofovir DF was given at dose of 300 mg per day, followed in 24 months.
Results: ALT normalization and HBV DNA responses were found in 91.7% and 87.5%, respectively, of all patients. The mean of SWV was significantly improved after 24 months, from 2.16 ± 0.28 m/s down to 1.80± 0.22 m/s after 24 months of tenofovir treatment. Especially, 15 patients (31.2%) have obtained a remarkable improvement of fibrosis from F4 down to F3 or even F2.
Conclusion: Tenofovir treatment in patients with HBV- related compensated cirrhosis may provide not only biochemical and virological responses but also improves in liver fibrosis, especially after long-term treatment.

In-silico molecular docking study of novel derivatives of erlotinib in glioma
Authors: Tripathi Deepika , Imran Sabiha
Published: March 2020

Gliomas are primary brain tumours arises from the glial cells. Gliomas associated risk factor depend upon its degree of stage and grade. Erlotinib is a quinazoline derivative and antineoplastic agent that capacities as a Protein Kinase Inhibitor for Epidermal growth factor receptor (EGFR) related tyrosine kinase and widely used for treating non-small cell carcinoma. Erlotinib, (a tyrosine kinase inhibitor) has been found in the glioblastoma. ErbB (EGF family receptor tyrosine kinase) established to control cell survival, proliferation, migration, and differentiation. The ErbB receptor accounts for the restricted and redundant functions in the maintenance of tissues in adult mammals. Newly discovered drug targets and personalised treatments could be used to identify the characteristics of any individual’s tumorigenesis. To see the binding mode of deferent classes of erlotinib carefully chosen based on the structural comparison, we employed simulated screening and molecular docking based on the theory of evolution. The study consists of a simulated screening of around 3200 molecular derivatives of erlotinib and their molecular docking using a Lamarckian genetic algorithm. Molecular docking results showed binding energy ranging from -12.15 kcal/mol to -1.17 kcal/mol. Top 10 best-docked proteins were analyzed using UCSF Chimera and finding discovered the complicated atomic-scale properties between ligand and the target protein. Further wet lab study requires to study the actual binding as binding mode provided. To identify new inhibitors of EGFR with higher potency and specificity, additional information is needed for future designs molecules.
THE GREEN ECONOMY- AN APPROACH FOR THE SUSTAINABLE DEVELOPMENT OF THE FOOD INDUSTRY
Authors: Yordanova – Dinova Petya , Bichurova Iva
Published: March 2020

The proponents of the approach for sustainable development point out that its implementation requires: to halt the destruction of biodiversity; regarding the field of energy consumption – drastically reduce the use of non-renewable energy sources and orient towards renewable energy sources; stabilizing the concentration of greenhouse gases; achieving high quality of life and well-being; higher air and water quality; usage of safer chemical substances, pesticides and technologies; limitation of noise pollution; creating sustainable models of production and consumption; to use of technologies that conserve resources and the environment; to put national ecosystems under public control; to put on hold the uncontrolled growth of large cities and encourage the creation of small towns near the arable land. The economy itself is not an isolated and self-regulating subsystem, but exactly the opposite; it is embedded in another larger structure - the ecosystem. The idea of an environmentally conscious, competitive, green economy, contributing to sustainable development and resource efficiency - is one of the EU’s and UN’s measures for sustainable development. The term “green economy” was used in the United Nation’s Environment Program in 2011 – an economy that improves people’s well-being and creates social justice, reducing environmental risks and resource scarcity. The green economy helps to resolve the slowdown in economic growth and job losses, as well as the continued deterioration of environmental quality and ecosystem’s degradation. All this defines the green economy as an approach for achieving sustainable development. There are a number of conditions for the Bulgarian food industry to develop competitive advantages in green production, keeping in mind the trends in the introduction and consumption of bio products. In this regard, the main goal of this paper is to explore the opportunities for green specialization and green management of this sector needed to increase the competitiveness and profitability of its employees.
