Authors: Sakthivelu S. , Sethusundaram P. P. , Meignanamoorthy M. , Ravichandran M. 
Published: August 2020

AbstractMetal is the one of the important material in engineering materials because of their high strength to weight ratio. However the pure metals cannot be used as engineering materials due to their ductile property. So, to improve their mechanical properties, some of the high strength materials (not metals) were added as reinforcement to improve the mechanical properties of pure metals and the newly developed material is called as metal matrix composites. At present, Aluminium, Copper, Magnesium, Titanium and Iron have been used as matrix materials and materials like TiC, SiC, B4C, WC, Cr3C, TiO2, ZrO2, Gr, MoS2and Si3N4have been used as reinforcements. There are many processing techniques to fabricate metal matrix composites namely stir casting, ultra-sonic assisted casting, compo-casting, rheo casting, powder metallurgy technique, etc,. Among these, stir casting process is the most suitable and economical method to fabricate the metal matrix composites. In this article, an effort has been made to review the work of various researchers to fabricate metal matrix composites through stir casting process.
Petrographic and Chemical Research on Furnace Wastes From Individual Heating Furnaces and Boilers – Method for Identification of Co-Burning Municipal Waste
Authors: Szulik Wojciech , Jelonek Iwona 
Published: August 2020

Abstract
Numerous varieties of solid fuels have been employed for the production of heat in buildings and during cooking by utilizing furnaces and boilers. The most commonly used energy carriers include hard and brown coal, coke, and wood-based solid biofuels in the form of various types of pellets, briquettes, and chips. Notably, furnace and boiler users can combine these fuels in any way by changing their proportions. Generally, users of furnaces and boilers are known to co-burn solid fuels and various types of municipal waste. However, the municipal waste contains a number of organic compounds and toxic metals that can be released into the atmosphere during the combustion process; this poses a threat to the health of the environment and public. Herein, chemical and petrographic tests were performed to study the sources of furnace wastes. This research facilitates the identification of unacceptable substances such as plastics, metal filings, and glass.

Published: August 2020

Abstract
The first part of the paper concerns the natural deposition conditions of the 325/1 seam in the “W” coal mine, in the 102 longwall mining panel. It also presents the most important technical conditions regarding the exploitation at this longwall. To characterize the methane hazard in the longwall area, the parameters of ventilation and total methane concentrations as well as the volumetric flowrate of methane captured by the methane removal system, have been presented graphically. A significant part of the methane flow in the longwall area was released to the air flowing to the longwall. The most significant part of the article is the presentation and analysis of the results of prognoses of mean methane concentrations at the exhaust of the longwall area. The accuracy of the prognoses of methane concentration was verified using two methods: while not considering the release of methane to the air flowing to the longwall and while considering the total flowrate of methane to the ventilation air in the area of the 102 longwall. The method of forecast presented in the article has so far been checked for a 5-day and 6-day work day, as well as for walls operating in a non-regular mode. The article refers to the wall operating in a continuous mode, which required adaptation of the proposed method to this mode. The application of the one-day forecast proposed in the article allows for undertaking temporary methane prevention measures enabling safe use of the wall.

Abstract
Sustainability and eco-friendliness of the chain of supply is a subject of interest among many researchers. New eco-friendly solutions are being implemented in production, storage, and transportation of the entire chain of supply. This study focuses on pro-environmental solutions related to warehouse management. The publication describes a project of installing a solar photovoltaic (PV) system to generate electric power at the H&W Warehouse in New Brunswick, New Jersey. The purpose of this publication is to demonstrate the financial and environmental benefits of using sustainable forms of energy. The environmental benefits were calculated from the perspective of lowering the amount of carbon dioxide (CO2) released into the atmosphere. The financial benefits were determined by calculating the net present value (NPV), internal rate of return (IRR) and profitability index (PI) as well as regular and discounted payback. A computer simulation was being used as the research method. Calculations included in the publication have proven that the project being considered is beneficial from the financial and environmental perspectives.

The method of expert assessments allowed to rank these activities in order to establish the sequence of their implementation in cities in order to bring their state closer to the “livable city”.
When Art is Religion and Vice Versa. Six Perspectives on the Relationship between Art and Religion
Authors: Bosman Frank G. 
Published: August 2020

Abstract
In the discussion of religion and art, it is quite difficult to exactly define what makes art ‘religious’. In this article, the author suggest six different perspectives in which a work of art—any work of art—could be interpreted as ‘religious’, as an embodiment of the complex relationship between art and religion. These perspectives are not mutually exclusive: one and the same art work could be approached on multiple levels at once. Nor do they disqualify other methodologies of studying art and religion. These perspectives provide conceptual windows to understand what people (could) mean when they discuss religious art. The six perspectives are: (1) material, (2) contextual, (3) referential, (4) reflexive, (5) ritual, and (6) existential. They vary from the more or less objective to the more subjective, and as such from artist-intended to viewer/listener-perceived (with or without help of clues provided by the artist and/or the object itself). The author illustrates who these different perspectives can vary in defining certain pieces of art as religious by using three very different case studies: the Isenheimer Altarpiece, one of Hugo Ball’s famous sound poems, and the digital game Child of Light.
Holy Crisis. On the Problem that Espouses Modern Art to Modern Spirituality
Authors: De Kesel Marc 
Published: August 2020

AbstractVisual art owes its modernity from the crisis it fell into in the midst of the nineteenth century. Courbet’s call for realism questioned the foundation of the art of his time. The incapacity of the series of ‘-isms’ that followed to answer Courbet’s call, pointed to a crisis not only in art, but in the then emerging non-artistic visual culture in general. In fact, Courbet’s call questioned the image paradigm that was in force since the Renaissance: the one of ‘representation’. The crisis of art laid bare the crisis of the representation paradigm. Modern art’s complex relation to religion and spirituality must be understood in the context of this paradigm crisis. Although generally anti-religious, modern art often keeps on being fascinated by religion, spirituality, and mysticism. The ‘religious’, the ‘holy’, the ‘sanctity’ modern art is inclined to, is linked to the crisis it originates from. Does this reference to the religious and the spiritual, then, constitute the answer to that crisis? I defend the thesis that it rather affirms this very crisis. If there is something ‘holy’ in art, it is not the answer to which it makes people long, but it is art’s inherent crisis itself. If art has a ‘holy’ mission, it is to keep that crisis on the agenda of modernity.

Published: August 2020

Abstract
To perform their business operations, telecommunication companies need to consume energy. This paper aims to analyze and compare the energy consumption and their greenhouse gas emissions for there of the biggest telecommunication companies: Vodafone, Orange and Telekom. Although the scientific literature proposed some analysis on the environmental measures that the telecommunication companies have to take, there is a shortage of researchers focused on GRI reporting data and the pairwise comparison method. The authors compared these telecommunication companies’ emissions under the following criteria: energy consumption (GRI 302-1), scope 1 (GRI 305-1), scope 2 (GRI 305-2) and scope 3 (GRI 305-3) greenhouse gas emissions, reduction of emissions (GRI 305-5), using the pairwise comparison method. To reduce their emissions, companies developed a sustainability strategy. This paper will further emphasize what are the plans to reduce emissions for the company which, following the analysis, pollutes the most. To provide an overview of the future of the company which, by the analysis, pollutes the most, the authors have identified and analyzed what are the main actions that the company should take to reduce their impact on the environment. To do so, the authors firstly analyze the causes of the pollution produced by the telecommunication company using Ishikawa diagram. Then, it identifies what are the main organizational processes that can be improved using APQC standardization, to show that the improvement can be made if the organization adjusts their organizational processes. This paper is an enhancement to the studies form the field because it provides a comparative analysis on three of the most competitive telecommunication companies in the world, uses GRI criteria and pairwise comparison method and gives an overview on the next steps for the telecommunication company to reduce their greenhouse gas emissions.

Published: August 2020

Abstract
In the context of new environmental paradigms for the efficient customization of both traditional and renewable energy systems, the international regulations aim to be effective sources of alignment. The control practices in a big state-owned enterprise are the concepts implemented in this paper into a multi-criteria decision-making model for understanding, observing and accommodate the personnel for reaching high service quality. The best practices for effective policy design are alternatives in an Analytic Network Processes model designed and estimated by the staff in the audit department of the Romanian Regulatory Authority for Energy (RRAE). This model integrates all the national and international regulations at which the Romanian Regulatory Authority for Energy adhered and it determines what is the practical measures need to be taken at the level of each and every employee, in terms of individual forms of evaluation, so that principles regarding the implementation of the energy efficient systems produce tangible effects. The conceptual instrument considered for the effective alignment is the internal marketing. Internal marketing as a method built the foundation of a multi-criteria decision-making model whose alternatives are employees” evaluations forms. The model designed and estimated by staff in the audit department of the Romanian Regulatory Authority for Energy is developed using the analytic network processes theory (ANP) and the SuperDecisions software.
Impediments in cluster development: the case of Târnave valley
Authors: Tancelov Liane , Cojanu Valentin 
Published: August 2020

Abstract
Many years after the fall of communism, the Romanian wine industry has been still struggling to overcome lot of challenges such as erratic weather, unfair competition, lack of investments or the need for a clear vision of the future path of growth. The industry has reached eventually a level of maturity although there is still much to be done in terms of, among others, network-oriented management skills and the acknowledgement of the importance of the role of location for upgrading competitive advantages. Cluster development initiatives have become lately an important direction of economic policy, building on earlier macroeconomic stabilization efforts, opening up markets and reducing business costs. Companies that operate within a cluster, as opposed to those that are not integrated in such agglomerations, benefit from externalities thanks to their location, have better access to specialized suppliers, technological improvements and skilled labor, as well as direct connections to specialized knowledge flows. Is cluster formation and development a driver for the revival of the Romanian wine industry? What are the impediments that delay further progress? To answer these questions, a qualitative research was conducted with support of statistical data collected mainly from the Global Competitiveness Report, the Romanian Ministry of Agriculture and Rural Development, the National Institute of Statistics, and the International Organization of Vine and Wine. The paper focuses on the case of the vine and wine region of the Târnave Valley to understand the impediments for cluster development.
Considerations regarding the effectiveness of Risk Management for Internal Managerial Control System
Authors: Filip Cosmin 
Published: August 2020

Abstract
The paper presents a systemic analysis of the key factors of risk management for the internal managerial control (IMC) system for public entities in Romania. The risk management approach offers a broad view regarding the necessary tasks for having a rigorous, efficient, effective and transparent use of public funds. The necessity of taking a managerial decision on a current matter has its own peculiarities and effects, involving the actual way and manner in which the entity in question will go further. The effects of this kind of decisions can affect the entity in some precise moments. In this point, risk management should be present, according to the applicable approaches, in order to evaluate, among other things, the vulnerability of the system which is exposed to the effects of a decision that has been taken into account. Developing an internal control system is perceived as a process that involves improving performance and governance, rather than introducing a new, additional system. The paper is presenting some considerations regarding the effectiveness of risk management approach used in Romanian public entities, based on the latest reports published. There are also pointed out some principal causes for this implementation level of Risk management Standard, along with some selective proposals for improving the results of this risk based approach
The history of economics and the Constructal Theory
Authors: Isaic Radu , Păun Cristian 
Published: August 2020

Abstract
The signs of a new crisis appear. Some countries are moving towards real assets (gold, oil); the real estate market froze, as did the credit market; sales are on a global decline. The world has become accustomed to economic cycles and crises. At the theoretical level, efforts are aimed at finding practical methods of prevention and especially of combating the negative effects on economic cycles. The market of theories regarding the internal causes and mechanisms of economic cycles has stabilized. The theoretical barricades were formed and strengthened and now the projectiles are thrown from one side to another. Demand theories and supply theories give partial explanations, but with claims of total theories. Is it possible to see something new at the theoretical level about the causes and mechanisms of economic cycles? We think so. We believe that the Constructal Theory of Professor Adrian Bejan has an explanatory power over the present theories about the causes of the economic cycles. The perspective offered by this theory is new and offers explanations for aspects that are difficult to understand in other theories. Through this article we want a rewriting of economic history, from the perspective and through the lens of this theory. We believe that we offer a broader and deeper explanation of the causes of economic cycles using a theoretical tool borrowed from other sciences, but with great explanatory powers in the social sciences. We will rewrite the economic history by discussing: S-evolution of economic stages; overlapping economic flow systems; systems evolving from one another; increased resource consumption and increased resource efficiency. The results of this study indicate that abusive interventions in the economic system create problems. The economic system, which is essentially a flow system, like any other system, must be allowed to evolve freely.

Published: August 2020

Abstract
In the current pandemic conditions that have covered the whole world between individual contracts of special type, the contract with work at home has acquired a priority place. Likewise, telework, regulated in Romania since 2018 and considered a new form of work organization, has also proved its effectiveness. In this context, however, it is necessary to identify the advantages and disadvantages of working in the form of work at home or telework and to draw guidelines for future legislative changes in this area.
The Concept of Urban Agriculture – Historical Development and Tendencies
Authors: Dobele Madara , Zvirbule Andra 
Published: August 2020

Abstract
The change in the concept of urban agriculture has been driven by social, political and economic factors, changing the role of agriculture in the urban environment. From the second half of 20th century topicality and practices of urban agriculture are growing widely not only in social initiatives but also in scientific research (the number of articles in scientific databases has increased 18-30 times since 2000). Growing interest has identified various variations and tendencies in the interpretation of the concept of urban agriculture, having regard to the current United Nations definition that is broad, but in research works and case studies researchers adapt the definitions to the local characteristics and aim of the study, thus creating a number of risks in the interpretation of the concept, including limited possibilities for quantitative comparisons between studies. The aim of the article is to identify the historical development stages of the concept of urban agriculture and to determine the main research tendencies in its application. To achieve this aim, the method of monographic and descriptive analysis was used for theoretical discussion, analysis, synthesis and deduction - for information gathering, logical systematization and classification. As a result of the study, it was identified that the concept of urban agriculture is developed in three different stages - originally associated with the technical solutions of urban planning for providing food for city dwellers, it is currently developing in tendencies of different directions: analysis of agriculture’s role in urban areas (including mitigating climate change risks), classification of types of urban agriculture, opportunities for adapting innovations and technological solutions to urban agriculture, the place and context of urban agriculture for sustainable development in the circumstances of urbanization. Such in-depth research of the experience and impact of urban agriculture on sustainable development could increase dynamically due to environmental considerations, aspect of the circular economy, and new paradigms in planning urban and peri-urban areas.
