Purpose - This paper proposes a roadmap for the sustainability of operations based on the principles and practices taken from Integrated Management Systems (IMS) and Business Process Management (BPM).Theoretical framework - Companies must consider results based on the economic, social, and environmental dimensions of the Triple Bottom Line, and as such, some researchers point to the contribution made by IMS for sustainability. Another important aspect of changing to more sustainable business models is organizational structure. BPM focuses on implementing horizontal management in the organization through business processes.Design/methodology/approach – Within this context, a Systematic Literature Review (SLR) was carried out to identify IMS and BPM principles, practices and techniques, then a roadmap was designed and field research was carried out by specialists.Findings - Field research findings indicate that the roadmap represents a framework which can support organizations to achieve their sustainability goals.Research limitations/implications - One of the limitations in the study was the reduced number of specialists who analyzed the roadmap. Therefore, it is suggested, as a further study, that this roadmap is validated by other experts, including people from other countries. Another limitation is that the study must progress further on the issues of implementation posed by the proposed roadmap. As such, a further study should be carried out to address this point.Originality/value - This study uses concepts that have already been consolidated in the literature (IMS and BPM) as support for companies that seek to become more sustainable.Key words - Integrated Management System; Business Process Management; Roadmap; Sustainability; IMS; BPM.

In this work, we introduce the magnetic Schrödinger operator corresponding to the generalized Dirichlet problem. We prove its self-adjointness and discreteness of the spectrum in bounded domains in the multidimensional case. We also prove the basis property of its eigenfunctions in the Lebesgue space and in the magnetic Sobolev space. We give a new characteristic of the definition domain of the magnetic Schrödinger operator. We investigate the existence and uniqueness of a solution of the magnetic Schrödinger equation with a spectral parameter. It is proved that if the spectral parameter is different from the eigenvalues, then the first generalized Dirichlet problem has a unique solution. We then find the solvability condition for the generalized Dirichlet problem when the spectral parameter coincides with the eigenvalue of the Schrödinger magnetic operator.

In internal ballistics of barrel systems, a promising trend is related to the increasing of projectile muzzle velocity by means of high-energy propellants utilized as a traveling charge. The use of a loading scheme with a traveling charge allows one to increase the loading density and to redistribute the energy of powder gases in the space behind the projectile, which leads to a significant increase in the muzzle velocity of the projectile. To attain the listed advantages, it is necessary to know the laws of dispersion and combustion of the propellants used as traveling charges, providing non-digressive gas entry into the charge space. In this work, a comprehensive experimental and theoretical study of the laws of dispersion and combustion of high-density propellants under dynamic pressures, provided in a model ballistic installation, is carried out. The main ballistic characteristics of shots are obtained, which use a classic scheme of loading with a propellant charge made of pyroxylin powder and a scheme with a traveling charge, where, in addition to the propellant charge, a high-density propellant is included. All the experiments are simulated in a software package, taking into account the presence of the high-density propellants in the propellant charge, dispersing into individual particles that burn out while moving along the barrel. As a result of comparing the calculated and experimental data, plausible patterns of the distribution of gas-dynamic parameters are obtained using the classic loading scheme and the loading scheme with a travelling high-density propellant charge.

In this paper, the longitudinal-radial vibrations of the elastic cylindrical shell filled with a viscous compressible fluid are studied using the mathematical model proposed. The general equations for the longitudinal-radial vibrations of the shell made of the homogeneous and isotropic material are derived. These equations can be used to obtain refined equations of vibrations. The proposed algorithm allows one to uniquely determine the stress-strain state of points in any section of the considered hydroelastic system using the field of the required functions in coordinates and time. The benchmark problem of harmonic oscillations in a cylindrical shell with a viscous fluid is solved. The dependences of the frequency on the wave number are obtained for various shell- fluid interaction cases.

Published: March 2021

Stress and strain distributions in the Yakutsk-Vilyui large igneous province (LIP) are numerically simulated under geotectonic extension. A two-dimensional model of the geological structure of a part of the Yakutsk-Vilyui LIP is developed using the geophysical data from the profile “Craton-1980”. However, these geophysical data can only be a source of the geometrical model and elastic properties of Earth’s layers. To describe non-elastic strains during the geological process, the Drucker-Prager-Nikolaevsky model of plasticity is adopted. For elastoplastic analysis of the geotectonic process, the “Jelly Sandwich” shear strength model for the continental lithosphere is used, which is based on the variation of the strength properties with depth. Zones of shear stress concentration and plastic strain localization are observed as a result of the extension in the Lindenskaya basin and Khapchagaiskaya reclamation complying with oil and gas deposit locations in the Yakutia region. Stress components have non-linear distributions determined by the dependence of strength properties on the depth and structural inhomogeneity of continental lithosphere. The pressure distribution obtained in the simulation can partially complement the geological information employed when analyzing the possibility of phase transitions in the rocks in different locations of the studied region.

The subcritical elastoplastic deformation and the fracturing of an element of a finite element continuum in the Ansys Workbench complex are considered. When solving the elastoplastic problem of the subcritical deformation, a finite element with the failure criterion reached is selected. In a pre-fracture state of the element, the nodal forces provided by the interaction with an adjacent element are determined using the Ansys Workbench internal procedure. The following step is the consideration of the varying stress-strain state of the body during the element destruction. The elastoplastic problem is solved in the conditions of simple unloading of the body surface adjacent to the destructible element while maintaining the external load corresponding to the destruction initiation. When implementing the local unloading, a possibility of the new plastic region formation and the partial unloading are studied. As a result, the stress-strain state of the body at the beginning of local unloading is not the same as that at the end of the process. The proposed approach differs from the “element killing” procedure when the element stiffness after the failure criterion reached is assumed to be close to zero. The paper provides solutions to the problems of deformation of elastic and elastoplastic plates with a side cut taking into account their element destruction.

The mathematical model and results of a numerical study of swirling turbulent air flow characteristics in a semi-closed cylinder rotating around a symmetry axis are presented. A physical and mathematical model is used to describe aerodynamics of the stationary isothermal axisymmetric swirling flow, which includes the Navier-Stokes equations in cylindrical coordinates. The study of turbulence characteristics is carried out using the composite model Menter SST (Shear Stress Transport). The numerical solution is obtained using a chess grid. Nodes for axial and radial velocity components are located in the middle of the control volume faces for scalar quantities. Calculations are performed on a grid with 2000 and 1700 nodes in the axial and radial directions, respectively. The grid refinement is performed near the walls and in the areas with large velocity gradients. The calculated results show that the main grid refinement by 2 times in the axial and radial coordinates leads to a change in the values of the main variables by less than 1%. It is shown that the flow structure is determined by the rotational speed and cylinder height. Analyzing the calculated results, the ratio of the cylinder height to the angular velocity of the cylinder rotation is obtained, which ensures the formation of a quasi-solid rotation zone in the near-edge region.

Authors: Yang Jie , Wang Fei , Chen Baoan
Published: March 2021

The WD40 repeat (WDR) domain is one of the most abundant protein interaction domains in the human proteome. More than 360 protein interaction domains have been annotated thus far. The WDR domains mediate interactions with peptide regions of important interaction partners in a variety of biological processes. Proteins with the WDR domain which typically contains a seven-bladed β propeller, are continuously being discovered. They represent a large class of proteins that are likely to play important roles. WD40 repeat domain-containing protein 76 (WDR76) is a member of WDR domain-containing proteins. Although it remains poorly understood, it is potentially involved in DNA damage repair, apoptosis, cell cycle progression, and gene expression regulation. Ongoing research on WDR76 is increasing the knowledge regarding its basic functions and role in different pathophysiological. The study of WDR76 is challenging due to the complexity of its interactions with its partners. In the present review, we summarized the current knowledge regarding WDR76, its physiological functions, the close relationship with human diseases, and potential opportunities for target therapy.

75TH ANNIVERSARY OF THE UN: HOPES AND REALITIES
Authors: Kuzmin E. L.
Published: March 2021

Examining the history of the UN creation in the first part of the article, the author focuses on an exceptionally significant issue settled in 1945 during the Crimean Conference of the Heads of the Three Great Powers, namely: the order of voting in the UN Security Council. Various appeals to renounce the “veto” of permanent members of the UN Security Council enshrined in the UN Charter have become the main leitmotif of numerous attempts of the United States and their closest allies to revise the UN Charter. Reviewing such proposals, the author notes that populist ideas the essence of which constitutes the call to replace, based on the principles of equality of all States, an international Organization by a supranational structure whose activities would actually be based on the principle of “who has force, has power” have been disseminated in Western political and scientific circles.

The author goes on to consider the crucial question: whether the Organization have been able to cope with its main mission: to maintain international peace and security?

Listing the outstanding universal documents of our time developed in the bowels of the UN, the author calls the most notable, in his opinion, achievement of the Organization — a real liberation of dozens of countries in Asia, Africa and Latin America from colonial oppression. Analyzing the activities of the UN, the author acknowledges that the Organization in many respects is still far from its unifying convergent essence: the US and its NATO allies lead the policy aiming at crashing the system of international relations, based on the central role of the UN in world politics; the US promote a concept that implies the creation of closed alliances to develop and implement measures bypassing the UN. Amid such realities, Russia, seeking to strengthen multilateral principles in international affairs, emphasizes the creation of a self-regulating international system, which requires collective leadership of the leading States that is represented geographically and civilizationally, and exercised with full respect for the central and coordinating role of the United Nations.

The article also draws attention to the fact that modern reality identifies more and more intractable problems, which often lead to the “autonomization” of international law: “niches” that are not filled with legal material inevitably give rise to situations where the gaps concerned are governed by particular and special rules based on bilateral or regional foundations, The author sees the empowerment of international law in the approval of principles of intercivilizational communication, the pursuance of synthesis of various legal systems, ideologies, cultures, religions and other spiritual values, which would provide a reliable basis for strengthening the importance and influence of international law.
DIFFERENTIATION OF BASIC PRINCIPLES AND NORMS JUS COGENSAS CONCEPTS OF THE THEORY AND PRACTICE OF MODERN INTERNATIONAL LAW
Authors: Anufrieva L. Р.
Published: March 2021

The article deals with both juxtaposition and differentiation of the concepts of “basic principles” and jus cogens (peremptory norms of general international law) as phenomena of international legal reality from the point of view of their location in the theory and practice of international law. Not limited to fixing a serious problem that exists in the field of research and consists in a considerable variety of terms having complicated the apparatus of modern international legal science, this article provides a consistent differentiation of many other individual notions which fall under the head of the principles of international law. Along with this, as the key-stone of the problem under consideration the broader “layer” — the analysis of the “principle” as a category of legal science shall be subject to accentuation as core, dominant in modern international law. Since the “basic principles” are one of the main concepts of both the system of international law and its science, they are evaluated primarily from the point of view of their functional role in the legal regulation of interstate relationships. While being compared with the peremptory norms of general international law (jus cogens), the basic principles are also envisaged in this article aiming to determine their importance for the theory and practice of international law in general.
THE INTERNATIONAL PROTECTION OF THE RIGHTS OF ENVIRONMENTAL MIGRANTS: ACTIVITIES OF UNITED NATIONS’ ORGANS, PROGRAMMES, AND AGENCIES
Authors: MARKOVA E. Yu.
Published: March 2021

The article examines and analyzes the work of the UN Organs, Programmes and Agencies in solving the problem of protecting the rights of environmental migrants. It demonstrates the gradual recognition at the international level of the fact that it is necessary to protect the rights of people forced to migrate to safe and habitable areas in conditions of climate change (the rights of environmental migrants). Despite the fact that climate change has not been recognized as a factor directly in fl uencing migration and that the climate change is considered only in conjunction with other causes (economic, political, social, etc.), the UN Organs, Programmes and Agencies are working on research and recognition of the negative impact of the climate change on the full enjoyment of human rights. The author suggests that such work of the UN system will help to form and consolidate the international legal status of environmental migrants and subsequently to solve the problem of the environmental migration.
INTERNATIONAL LAWYERS AS A PROFESSIONAL COMMUNITY
Authors: KOZHEUROV Ya. S.
Published: March 2021

Even though international lawyers represent a variety of countries with diff erent cultures and legal traditions, with diff erent levels of economic development and political goals, they constitute a unique professional community ("a kind of invisible college dedicated to a common intellectual enterprise", according to O. Schachter) speaking one language — the language of international law. In international relations, in the absence of a higher (supranational) authority, lawyers sometimes become the only ones who "civilize" the protection of national interests, according to M. Koskenniemi; it causes specifi c ethical professional problems, which are considered on the example of the work of a lawyer in foreign policy departments, in international organizations and in international courts. The article substantiates the idea that international lawyers, due to the huge creative potential of their profession, are, in fact, the "architects" of international law and the system in which it exists.

AIM: To evaluate the anatomic and visual outcomes of 25-gauge vitrectomy combined with air tamponade for the treatment of idiopathic macular hole (IMH).
METHODS: Thirty eyes of 27 patients with IMH were included in this prospective interventional study. All patients underwent 25-gauge pars plana vitrectomy (PPV) combined with phacoemulsification and air tamponade. Best corrected visual acuity [BCVA; logarithm of the minimum angle of resolution (logMAR)], perimetry and multifocal electroretinography (mfERG) were conducted before and after the operation. Anatomical changes were evaluated with optical coherence tomography (OCT).
RESULTS: The macular holes closed successfully in 28 eyes after the primary vitrectomy. The mean BCVA improved from 0.72±0.22 logMAR preoperatively to 0.29±0.18 logMAR postoperatively (P<0.001). In the visual field of central 10°, the average mean deviation (MD) decreased from -3.59±1.83 dB preoperatively to -2.51±1.36 dB postoperatively (P<0.001) and the average pattern standard deviation (PSD) decreased from 1.86±0.68 dB preoperatively to 1.33±0.32 dB postoperatively (P=0.001). The retinal response densities of mfERG in the foveal and perifoveal area increased significantly, and implicit times of rings 4-6 prolonged significantly too (P<0.05). The symptom duration and baseline N1 amplitude densities at ring 1 had a significant impact on postoperative BCVA (P<0.001, P=0.001, respectively).
CONCLUSION: The 25-gauge PPV and air tamponade with 1d prone positioning produced favorable anatomic and functional outcomes.
Avaliação crítica sobre a legislação brasileira quanto ao uso de ácido ascórbico como aditivo alimentar em sucos e polpas de frutas
Authors: Da Costa Ana Paula Souza , Coelho Raquel Macedo Dantas
Published: March 2021

O ácido ascórbico, também denominado vitamina C, é hidrossolúvel e termolábil. Os seres humanos são incapazes de sintetizar o ácido ascórbico, por isso valem-se essencialmente da alimentação através de frutas, hortaliças e vísceras para suprir sua demanda. Além do seu valor nutricional, o ácido ascórbico é empregado como aditivo alimentar devido o seu caráter antioxidante. Este trabalho objetivou analisar criticamente as Instruções Normativas Nº 37 de 01 de outubro 2018, do Ministério da Agricultura, Pecuária e Abastecimento - MAPA e a Instrução Normativa nº 37, de 01 de outubro de 2018 - MAPA: a primeira, a qual requer um teor mínimo de ácido ascórbico de origem natural para determinados sucos e polpas de fruta; e a segunda por, ao mesmo tempo, permitir o uso do aditivo ácido ascórbico (INS 300) para esses tipos de bebidas. A partir desta análise crítica evidenciou-se esta contradição que compromete a ação fiscalizatória do cumprimento dos padrões de identidade e qualidade para sucos e polpas de fruta, pois possibilita mascarar alterações de qualidade provocadas por falhas no pós-colheita, processamento, transporte e armazenamento denunciadas pela degradação da vitamina C. Convém que não seja permitido o uso deste aditivo para tais bebidas.
Influence of Freezing on Muscles of Rainbow Trout (Oncorhynchus mykiss): A Histological and Microbiological Study
Authors: Strateva M. , Penchev G. , Stratev D.
Published: March 2021

Background: Freezing is a common and ancient method for preservation of foods which is applicable both under household and industrial conditions. The objective of the study was to establish histological and microbiological changes in dorsal and abdominal muscles of rainbow trout (Oncorhynchus mykiss) after freezing once and twice.
Methods: Forty-five fresh rainbow trout specimens were distributed into three groups of 15 fish each. The first group was subjected to histological and microbiological analysis immediately after delivery at the laboratory. The second fish group was frozen at -18 °C for 15 days, while the third group of fish was frozen at -18 °C for 15 days, thawed and frozen again at -18 °C for 15 days. Data were analyzed using GraphPad InStat 3 software.
Results: After freezing once, muscle fibers with intracellular void spaces were observed and retained stable peripheral boundary. In some muscle fibers, the endomysium boundaries were visible and with retained integrity. After freezing twice, damages and deformities were observed resulting in completely destructured muscle fibers. Large void spaces among the muscle fibers and bundles were greatly the result of shrinking and grouping of fibers and the laceration of endomysium and perimysium internum. Total microbial count and Enterobacteriaceae count had no significant differences (p>0.05) between fresh, frozen once, and frozen twice trout.
Conclusion: Muscles of rainbow trout (O. mykiss) are histologically damaged to a greater extent after freezing twice and thawing. However, microbiological indicators had no change significantly after freezing once and twice.

Published: March 2021

Background: Tuber aestivum Vittad., known as black summer truffle, represents high-value food especially used as garnishment in nouvelle cuisine. The aim of this study was to investigate on the viable microbial populations associated with T. aestivum ascomata collected in different sites of Sicily and one locality of Umbria (Italy).
Methods: The ripe ascomata of black summer truffles were collected from Central Italy. Cell densities of spoilage bacteria, fecal indicators, potential pathogens, yeasts, and molds were analyzed. Statistical analysis was conducted with XLSTAT software.
Results: The microbiological counts of truffles ranged between 6.00 and 9.63 log Colony Forming Unit (CFU)/g for total mesophilic count and between 6.18 and 8.55 log CFU/g for total psychrotrophic count; pseudomonads were in the range 6.98-9.28 log CFU/g. Listeria spp. and coagulase-positive streptococci detected in no samples. Coagulase-negative streptococci were found in some samples with 2.11-4.76 log CFU/g levels. Yeasts and filamentous fungi were detected at consistent levels of 3.60-7.81 log CFU/g. Significant differences (p<0.01) were found between samples and also for all microbial groups.
Conclusion: This study evidenced that the common brushing procedure applied for preparation of truffles is not sufficient to eliminate microbial risks for consumers. The application of an efficient decontamination treatment is strongly suggested before consumption of fresh truffles.

Published: March 2021

Background: Drying is the one of the oldest methods for increasing the shelf life of food products. The objective of the present study was evaluation of effect of different drying temperatures on drying time and storage quality parameters of in-shell hazelnut.
Methods: Hazelnuts were dried as a thin layer at three temperatures (40, 50, and 60 °C). The time required for drying and quality parameters (lipid and protein content, acidity, and peroxide value) were evaluated. Besides, sensory and oxidation evaluations were performed in order to evaluate the effect of the drying temperatures on quality of hazelnuts before and after 6-month storage. Data were analyzed by SPSS software (V. 16.0).
Results: The mean drying times at 40, 50, and 60 °C were 29.75, 25, and 20.25 h, respectively. In fact, an inverse significant (p<0.05) relationship was observed between temperature and time of the hazelnuts drying process. The mean protein content of the hazelnuts dried at 40, 50, and 60 °C were 13.06, 12.83, and 13.62 (% dry basis), respectively. Lipid content of the samples were significantly (p<0.05) increased with drying temperature. The lowest acidity and peroxide values were recorded for the samples dried at 60 °C with the values of 0.15% oleic acid and 1.3 meq/kg, respectively. Sensory results showed that all of the treated hazelnuts were acceptable after six months storage.
Conclusion: The evidences of the present study point that in-shell hazelnuts drying at temperature of 60 °C can lead to production of good quality products.

Background: Sodium caseinate is a rich source of protein and minerals originating from animals. Numerous food and non-food products are made from sodium caseinate. The present study investigated the chemical components (moisture, crude protein, ash, and soluble crude protein) of sodium caseinate prepared by different acids and drying techniques.
Methods: A completely randomized factorial design was used by different acids including hydrochloric acid (HCl) and acetic acid, and also drying methods including oven (50 °C for 48 h) and freeze drying (-40 °C for 48 h). In each experimental group, sodium caseinate was obtained for determination of moisture, crude protein, ash, and soluble crude protein. Data were statistically evaluated using an ANOVA in SPSS 18.0.
Results: The interaction of both acids and drying methods significantly (p<0.01) affected moisture, crud protein, and ash content. HCl treatment coupled with freeze drying was the best combination, resulting in an appreciably higher content of crude protein (52.90%), moisture (5.38%), and soluble protein (0.85%).
Conclusion: The kinds of acid and drying method altered the chemically profile of sodium caseinate. The combination of HCl and freeze drying could be the considered as the best approach, resulting in good chemical characteristics of sodium caseinate.

Authors: ÜMİT Ceyda
Published: March 2021

5607 sayılı Kaçakçılıkla Mücadele Kanunu kapsamında etkin pişmanlık uygulaması, yasa uygulayıcı makamlar nezdinde ve ceza hukuku öğretisinde tartışmalı bir alandır. Cezayı kaldıran veya azaltan şahsi neden olan etkin pişmanlığın kendine özgü hukuki niteliği, her somut olayın farklı özellikleri ve failin iradi davranışları dikkate alınarak etkin pişmanlık koşullarının son derece kapsamlı değerlendirilmesini zorunlu kılmaktadır. 5607 sayılı Kaçakçılıkla Mücadele Kanunu, etkin pişmanlığı tek bir madde çatısı altında ancak hukuki koşulları, nitelikleri ve unsurları değişen üç farklı yasal formda düzenlediğinden farklı uygulama ve yorumlarla karşılaşılmaktadır. Bu çalışma; uygulama birliği sağlamak ve süregelen tartışmalara katkıda bulunmak üzere konunun kapsamlı analizi ile etkin pişmanlık düzenlemelerine açıklık kazandırmayı hedeflemektedir. Bu bağlamda etkin pişmanlığa dair kavramsal açıklamalar ile etkin pişmanlığın Türk Ceza Kanunundaki uygulaması açıklanmakta ve 5607 sayılı Kaçakçılıkla Mücadele Kanunu düzenlemesi, içtihat hukuku ve son gelişmeler ışığında irdelenmektedir. Ayrıca, yakın zamanda yürürlüğe giren yeni yasal düzenlemenin olası etkileri değerlendirilerek, en iyi uygulamaya yönelik çözüm önerileri sunulmaktadır.

Investment is one of the most crucial decisions that a company must create to achieve higher financial performance and to maintain long-term sustainability. This study predicts that two significant factors determine corporate investment, i.e., the firms’ corporate governance and capital structure. The article also assumes that companies that are aware and engage in environmental programs would find it much easier to gain investors’. This study used 39 units of analysis of 13 manufacturers listed on the Indonesia Stock Exchange that received a good ranking in PROPER during the 2016-2018 period and analyzed with structural equation modeling (SEM). This study finds that corporate governance is negatively related to the capital structure but positively related to corporate investment. However, the capital structure does not affect corporate investment implying environmental performance’s significance in leading corporate governance and enhancing corporate investment. Further research can extend the observation period, use other sectors as the sample, use the different indicators in each variable, and develop the relationship between variables on a broader framework.

This study aims to examine system interactivity affecting member commitment and intention to continue participating in the online hijabs community. At the same time, testing how the role of virtual sites in the form of posting in strengthening the relationship (moderate) system interactivity to continue to participate in the online hijabs community. An online hijabs community was researched because the problem observed in the research was relevant to the virtual community. Based on 358 valid responses from students in Surabaya who actively joined the online hijabs community obtained from questionnaires at each university in Surabaya, structural equations modeling (SEM) was used to test the research model. The results show that system interactivity affects commitment to the community, but does not affect the intentions of members to continue their participation in online hijabs communities. Likewise, commitment to the community does not stimulate the intentions of members to remain actively participating in online hijabs communities. Although, an interesting form of posting can strengthen the system’s interactivity relationship of members’ intentions to continue their participation in online communities. Implications for both marketing theory and practice, limitations, and future research on video storytelling in social media are discussed.
