SIMULATION OF AGGREGATION PROCESS IN CERIUM AND ZIRCONIUM DIOXIDE NANOPARTICLES

A study of the aggregative stability of the CeO2-ZrO2 system was carried out in various pH ranges of the medium. To create a mathematical model of the stability of aggregates, the generalized DLVO theory was taken. The parameters of the structural component of the potential energy of particle interaction are determined using the principle of minimum entropy production. The limiting particle sizes of an an aggregatively stable system are determined.

Comparison and analysis of energy loss and flow characteristics of T-junctions via secondary flow and entropy production

The energy loss and resistance effect of traditional local components widely used in HVAC systems in buildings are severe. To improve the significant energy loss effect, a method to reduce resistance and energy loss by inserting guide vanes in a confluent T-junction is proposed through full-scale experiments and numerical simulations, and the flow characteristics and energy loss distribution of the T-junction are analysed through the swirl intensity of the secondary flow and the entropy production principle. The energy loss reduction rates (ELRRs) of T-junctions are compared under different diameter ratios, branch angles, and flow ratios. The results show that the total energy loss coefficient of the T-junction with curved guide vanes is significantly smaller than that of the traditional T-junction. The maximum ELRR is 43.5% when the diameter ratio is 0.8 and the flow ratio is 0.2. The insertion of a guide vane cuts the large vortex into multiple small vortices, thereby weakening the entropy production and swirl intensity of the downstream secondary flow. Under different Reynolds numbers, the effect of the guide vane on reducing the resistance and energy loss of the T-junction is verified by full-scale experiments, and the experimental results are in excellent agreement with the simulation results. This study provides data support and a reference for the standardized and design of low-energy loss T-junctions in HVAC systems for the energy-saving operation of buildings.

Epipolythiodioxopiperazine-Based Natural Products: Building Blocks, Biosynthesis and Biological Activities.

Epipolythiodioxopiperazines (ETPs) are fungal secondary metabolites that share a 2,5-diketopiperazine scaffold built from two amino acids and bridged by a sulfide moiety. Modifications of the core and the amino acid side chains, for example by methylations, acetylations, hydroxylations, prenylations, halogenations, cyclizations, and truncations create the structural diversity of ETPs and contribute to their biological activity. However, the key feature responsible for the bioactivities of ETPs is their sulfide moiety. Over the last years, combinations of genome mining, reverse genetics, metabolomics, biochemistry, and structural biology deciphered principles of ETP production. Sulfurization via glutathione and uncovering of the thiols followed by either oxidation or methylation crystallized as fundamental steps that impact expression of the biosynthesis cluster, toxicity and secretion of the metabolite as well as self-tolerance of the producer. This article showcases structure and activity of prototype ETPs such as gliotoxin and discusses the current knowledge on the biosynthesis routes of these exceptional natural products.

Theorizing the Principles of Sustainable Production in the context of Circular Economy and Industry 4.0

The concept of Sustainable Production is evolving with changes triggered by the emergence of new economic and industrial models such as Circular Economy and Industry 4.0. However, most studies that currently link these concepts are based on the principles of Sustainable Production defined 20 years ago. Therefore, the primary aim of this study is to redefine the principles that should govern Sustainable Production operations in the transition towards a Circular Economy and smart industry models. To this end, an initial proposal of 11 principles was shared with 11 world-class experts (academics and practitioners) and a consensus proposal was sought through a Delphi Panel. Ten principles emerged from this study, which were evaluated by experts according to criteria of significance, parsimony, semantic consistency and empirical adequacy. Additionally, to study the relationships between the ten principles, the Interpretative Structural Model (ISM) technique was applied. The ISM technique identified which principles are independent of or dependent on each other and established relationships between the principles. The findings suggest that Principle 5 (“Prioritize employees' well-being”), Principle 6 (“Enhance management commitment to sustainability”), Principle 9 (“Measure and optimize sustainable processes”) and Principle 10 (“Boost the use of sustainable technologies”) help to establish an ideal context to enhance the development of the rest of the principles that characterize Sustainable Production. The presentation of the ten principles opens new possibilities for researchers while helping managers to better understand sustainability in terms of production and, therefore contribute to achieving SDG 12.

Kinetic theory of collisionless relaxation for systems with long-range interactions

We develop the kinetic theory of collisionless relaxation for systems with long-range interactions in relation to the statistical theory of Lynden-Bell. We treat the multi-level case. We make the connection between the kinetic equation obtained from the quasilinear theory of the Vlasov equation and the relaxation equation obtained from a maximum entropy production principle. We propose a method to close the infinite hierarchy of kinetic equations for the phase level moments and obtain a kinetic equation for the coarse-grained distribution function in the form of a generalized Landau, Lenard–Balescu or Kramers equation associated with a generalized form of entropy (Chavanis, 2004). This allows us to go beyond the two-level case associated with a Fermi–Dirac-type entropy. We discuss the numerous analogies with two-dimensional turbulence. We also mention possible applications of the present formalism to fermionic and bosonic dark matter halos.

Engineering practice of underground heat injection-enhanced gas extraction in low-permeability coal seams

ABSTRACT The heat injection mechanism for improving gas desorption, coal seam gas pressure, and coal seam permeability in the Yangquan mining area was investigated via theoretical analysis. This analysis was conducted to address the problems of poor permeability, difficult gas extraction, and low extraction efficiency of 15# coal seam. An underground heat injection-enhanced gas extraction technology was proposed; accordingly, a heat injection-enhanced gas extraction system was developed and appropriate extraction methods were devised. The findings of an industrial test on 15# coal seam in the coal mine show that the proposed technology not only increased the amount of gas extracted but also halved the extraction time and realized efficient gas extraction. Two mature underground heat injection-enhanced gas extraction methods were established. These methods have similar gas production principles in that the gas production speed and gas concentration in the heat injection stage are relatively low, while the average degree of improvement in the extraction stage after heat injection can reach more than 50 times. The average degree of improvement in gas production speed and gas concentration after the second heat injection is greater than that after the first.

RADAMS: Resilient and adaptive alert and attention management strategy against Informational Denial-of-Service (IDoS) attacks

Attacks exploiting human attentional vulnerability have posed severe threats to cybersecurity. In this work, we identify and formally define a new type of proactive attentional attacks called Informational Denial-of-Service (IDoS) attacks that generate a large volume of feint attacks to overload human operators and hide real attacks among feints. We incorporate human factors (e.g., levels of expertise, stress, and efficiency) and empirical psychological results (e.g., the Yerkes-Dodson law and the sunk cost fallacy) to model the operators’ attention dynamics and their decision-making processes along with the real-time alert monitoring and inspection. To assist human operators in dismissing the feints and escalating the real attacks timely and accurately, we develop a Resilient and Adaptive Data-driven alert and Attention Management Strategy (RADAMS) that de-emphasizes alerts selectively based on the abstracted category labels of the alerts. RADAMS uses reinforcement learning to achieve a customized and transferable design for various human operators and evolving IDoS attacks. The integrated modeling and theoretical analysis lead to the Product Principle of Attention (PPoA), fundamental limits, and the tradeoff among crucial human and economic factors. Experimental results corroborate that the proposed strategy outperforms the default strategy and can reduce the IDoS risk by as much as 20%. Besides, the strategy is resilient to large variations of costs, attack frequencies, and human attention capacities. We have recognized interesting phenomena such as attentional risk equivalency, attacker’s dilemma, and the half-truth optimal attack strategy.

Universal Principle for Large-Scale Production of a High-Quality Two-Dimensional Monolayer via Positive Charge-Driven Exfoliation

On the basis of the intrinsic characteristics of the layered materials, here we report a universal principle for the production of intact monolayers via layer-by-layer exfoliation from their bulk via positive charge doping. At experimental accessible densities (nc) of ∼1014 cm-2, various multilayer crystals, including graphite, hexagonal boron nitride, transition metal dichalcogenides, MXenes, and black phosphorus, can be exfoliated into the corresponding monolayers through ab initio density functional theory stimulations. The carrier critical thresholds for exfoliating are found to be nearly independent of thickness but dependent on surface size. The universality of positive charge-driven exfoliation originates from the common intrinsic characteristics of electronic structures for layered materials. The positively doped charges that preferentially accumulate near the surface induce interlayer repulsion, leading to layer-by-layer exfoliation when repulsion surpasses interlayer van der Waals force. This strategy may open the possibility of producing diverse high-quality two-dimensional monolayers with a small number of defects toward large-scale manufacturing.

The long cycle perspective on the emerging bio age

A combined perspective of long economic cycles and very long secular cycles of production principles is proposed to anticipate the major socioeconomic implications of the emerging (bio)technological paradigm. The analysis identifies three distinct shifts that shape and promote socioeconomic development in the next five to six decades: the material shift toward renewable resources, the actual technological shift as a confluence of technological mega-trends, and the control shift toward new knowledge elites and self-regulating systems. The strongest creative and disruptive effects of the new (bio)technological leitmotif are shown to materialize at the overlap of the successive shifts. The results suggest revisiting some priority fields of the current bioeconomy and related policies and chart out key challenges beyond the strategic policy horizon of 2050.

ДО ПИТАННЯ БІОЛОГІЧНОГО ЗАХИСТУ СВИНЕЙ, БЕЗПЕКИ СВИНОФЕРМ ТА ОХОРОНИ ДОВКІЛЛЯ

The purpose of the research is – to summarize measures on biological protection of pigs, safety of pig farms and environmental protection, taking into account EU standards for obtaining quality pig products. Research methods. Analytical research on the generalization of measures for biological protection of pigs, safety of pig farms and environmental protection was carried out by processing existing scientific reports, including EU regulatory requirements aimed at obtaining quality pig products. Research results. The procedure of biological protection of pigs is aimed at improving the physiological condition of animals and livestock productivity. During pork production, it is important to ensure the biological protection of animals to reduce the risk of spreading disease on pig farms. It is advisable to arrange a canopy on the playgrounds to protect pigs in bad weather and from the sun. With the intensification of pig farming, industrial practice shows an increase in the level of diseases of pigs associated with metabolic disorders in animals, the action of stressors, non-compliance with the parameters of the microclimate and feeding rules. In such conditions, preventive measures are especially important in the system of control of infectious and non-communicable diseases of pigs. Premises of pig farms after the completion of the technological cycle are subject to cleaning, keeping on sanitary rupture, ie the veterinary principle "everything is busy - everything is empty" must be observed. The safety of pig farms is a set of practical measures aimed at preventing the spread of infection to the farm and controlling the spread of infection within the farm. Biological safety of pig farms includes the following areas: biological isolation, biological regulation, biological protection. To protect the environment from pollution by pig farm waste, it is advisable to take the following measures. During the construction of pig farms it is necessary to observe sanitary gaps: to settlements not less than 1500 m, to other livestock facilities - 1000-1500 m. It is important to form a green belt, a strip of trees and shrubs around the pig farm - this is the most natural of all protective measures based on the fundamental principles of organic production. Conclusions. According to the results of analytical research, for the first time the measures on biological protection of pigs, safety of pig farms and environmental protection are summarized, taking into account EU standards for obtaining quality pig products. The procedure of biological protection of pigs is aimed at improving the physiological condition of animals and livestock productivity. The safety of pig farms is a set of practical measures aimed at preventing the spread of infection to the farm and controlling the spread of infection within the farm. Agricultural enterprises that have a significant impact on the environment are responsible for preventing and reducing the negative impact of their activities on the environment. The direction of livestock development, including pig breeding, namely the introduction of environmental requirements at different stages of implementation of modern technologies, the creation of farms adapted to EU regulations - this will ensure not only economic viability but also environmental and social responsibility of agribusiness in Ukraine. Key words: biological protection of pigs, EU regulatory requirements, environmental protection, resistance, pig breeding, pork, pig farm, technical means, technological measures.

Waste Control at Construction Project by Adopting Lean Management Tool for Quality Measurement Framework

Abstract: Lean manufacturing and lean construction have the same goals according to Paez et al. (2005): elimination of waste, cycle time reduction, and variability reduction. One of the ways of reaching the goals of lean construction is flow according to Paez et al. (2005). When trying to attain flow in construction one need to realize that there are differences between manufacturing and construction, which may make it difficult to attain the same flow between different processes, attained within manufacturing (Koskela, 1992). These differences are certain construction peculiarities such as one-of-a-kind projects, site production, temporary organization and regulatory intervention, aspects more common with construction projects than manufacturing. According to Koskela (1992) however, the same production principles apply and there is room for improvement when it comes to flow in the construction industry. By using lean thinking and lean tools and adapting them to the construction industry this master's thesis purpose is to develop a tool to identify and measure waste, guide in which order waste should be reduced and by this enabling estimations of potential consequences that might occur by implementing a lean approach at a construction site. This is of interest in order to bridge the research gap between conceptual lean construction and research based on empirical studies

Use of "Lean" Technologies in the Medical Examination of the Adult Population in the Ryazan Region

INTRODUCTION: The medical examination of the adult population is an important mechanism to preserve the labor potential of the country through the early detection of diseases and prevention of premature mortality. The active involvement of citizens in preventive measures and an increase in the availability of medical examinations are vectors in increasing the coverage of the population. One of the mechanisms for increasing availability is the use of "lean" technologies, which was realized in the Ryazan region as part of the project "Optimization of the Medical Examination Process".
 AIM: To evaluate the optimization of the medical examination of the adult population in the Ryazan region through the use of "lean" technologies.
 MATERIALS AND METHODS: The project was implemented based on a multidisciplinary clinical hospital with high planned tasks for the coverage of the adult population indicated for medical examination. In the implementation of the project, problems in the organization of the medical examination of the adult population were identified, maps of the current state and the target state were compiled, solutions to each identified problem were proposed, and a 4-month schedule of measures was made.
 RESULTS: The evaluation of the effectiveness of the project "Optimization of the Medical Examination Process" using "lean" technologies reduced the patient stay in the clinic by 1.7 times in the first stage of the medical examination and reduced the duration of this stage from 5 to 1.5 days. In the second stage, the total patient stay in the clinic was reduced two times, and the duration of this stage was reduced from 8 to 2 days. The throughput capacity of the pre-medical reception room of the medical prevention department increased from 48 to 100 people per day with a two-shift working schedule, which permitted fulfilling the planned annual tasks for medical examination by 100.0%.
 CONCLUSION: The successful experience of the introduction of the "lean" production principles in the medical examination of the adult population demonstrated increased effectiveness and availability of preventive measures for the population in the region.

Eco-friendly utilization of oilfield fracturing flow-back fluid and coal pitch for preparing slurry: Experiments and extended DLVO study

The fracturing flow-back fluid (FF), as the primary pollutant in oilfield exploitation, is challenging to handle because of the large output and complex components. In addition, large amounts of coal pitch (CP) are insufficiently utilized. In this study, based on the principle of clean production, three dispersants were employed to prepare CP-water slurry (CPWS) and CP-FF slurry (CPFS), which had the characteristics of high efficiency and low pollution. The feasibility of CPWS and CPFS and the influences of dispersants on their performance were systematically studied by measuring the viscosity, rheology and stability. Furthermore, the dispersion mechanisms of dispersants were investigated via adsorption, Zeta potential, and extended DLVO (EDLVO) theory. Results showed that replacing water with FF reduced the slurryability, while the stability was improved. The CPFS exhibited the shear-thinning characteristics, and the components in FF strengthened the pseudoplastic of slurry. Among the three dispersants, the adsorption capacity of AC-1215 was higher than that of PS and MF. And the inorganic salts in FF promoted the adsorption of dispersants. The calculation of interaction energies demonstrated that for CPFS without dispersant, the polar interaction energy played a dominant role, resulting in the aggregation of CP particles. The addition of AC-1215 maximized the total interaction energies (greater than zero) by introducing the steric hindrance energy, which was 1–4 orders of magnitude higher than other interaction energies.

The Use of Wood Pellets in the Production of High Quality Biocarbon Materials.

Biomass is one of the most important sources of renewable energy. One of the most widely used biomass biofuels is wood pellets. It is an economical, homogeneous and easy-to-use raw material. Biomass is used to generate low-emission energy utilizing the pyrolysis process. Pyrolysis allows for higher energy efficiency with the use of commonly available substrates. This thesis presents the results of research on the possibility of using the pyrolysis process to produce high-energy biocarbons from wood pellets. Data on basic energy parameters and explosivity of biocarbon dust were compiled as criteria for the attractiveness of the solution in terms of energy utility. The research used pellets made of oak, coniferous, and mixed sawdust, which were subjected to a pyrolysis process with varying temperature and time parameters. Carbon, ash, nitrogen, hydrogen, volatile substances, heavy metals, durability and calorific value of the tested materials were carried out. The highest increase in calorific value was determined to be 63% for biocarbons obtained at 500 ℃ and a time of 15 min, compared with the control sample. The highest calorific value among all analyzed materials was obtained from coniferous pellet biocarbon at 31.49 MJ kg−1. Parameters such as maximum explosion pressure, Pmax, maximum pressure increase over time, (dp/dt)max, and explosion rates, Kst max, were also analyzed. It was noted that biomass pyrolysis, which was previously pelletized, improved the energy parameters of the fuel and did not increase the risk class of dust explosion. The lowest and highest recorded values of Kst max for the analyzed materials were 76.53 and 94.75 bar s−1, respectively. The study concluded that the process used for processing solid biofuels did not affect the increase in the danger of dust explosion. The results presented in this article form the basis for further research to obtain detailed knowledge of the safety principles of production, storage, transport and use of these new fuels.

Biofuel Production and Its Impact on Global Food Security: A Review Article

The aim of this study is to shed light on the importance of biofuels as an alternative to conventional energy, in addition to the importance of preserving agricultural crops, which are the main source of this fuel, to maintain food security, especially in developing countries. The increase in global oil prices, in addition to the fear of global warming, are among the main factors that draw the world’s attention to searching for alternative sources of traditional energy, which are sustainable on the one hand, and on the other hand reduce carbon emissions. Therefore, the volume of global investment in renewable energy in general, and in liquid biofuels and biomass in particular, has increased. Global fears emerged that the excessive conversion of large farms suitable for growing food to energy production would threaten global food security. In the first ten years of the new millennium, biofuel production increased fivefold, and the largest increase in biofuel production was recorded in 2007-2008, coinciding with a sharp rise in food prices. Compared to the average food prices in the period 2002-2004, the average global prices of cereals, oils and fats traded were 2 to 2.5 times higher in 2008, this continuous increase in the use of food crops to produce biofuels has reflected on global food security. Accordingly, this review article will address previous studies on biofuel production; identify the theoretical framework for the concept of biofuels and its characteristics, and the relationship between biofuels and food security. In this study, we presented biofuels, which are considered one of the important categories in the field of renewable energy and its environmental and economic effects, as well as the experiences of some countries in its production, and the possibility of benefiting from the natural resources available for its production. We will discuss the scientific (chemical) principles of biofuel production.

Biology: Motion is Function.

In 1966 Francis Crick declared that: “The ultimate aim of the modern movement in biology is to explain all biology in terms of physics and chemistry.” This motivated us to contemplate approaches that unify biology at a fundamental level. Exploration led us to consider the features of energy, entropy, and motion. Overall, it can be considered that motion of matter is the feature of life function. No motion. No function. In initial work we evaluated the hypothesis that the scope for biologic function is mediated mechanistically by a differential for energy transfer. Maximal treadmill running capacity served as a proxy for energy transfer. The span for capacity was estimated “biologically” by application of two-way artificial selection in rats for running capacity. Consistent with our “Energy Transfer Hypothesis” (ETH), low physical health and dysfunction segregated with low running capacity and high physical health and function segregated with high running capacity. The high energy yield of aerobic metabolism is also consonant with the ETH; that is, amongst the elements of the universe, oxygen is second only to fluorine in electronegativity. Although we deem these energy findings possibly correct, they are based on correlation and do not illuminate function via fundamental principles. For consideration of life, Entropy (2nd Law of thermodynamics) can be viewed as an open system that exchanges energy with the universe operating via nonequilibrium thermodynamics. The Principle of Maximal Entropy Production (MEP) states that: If a source of free energy is present, complex systems can intercept the free energy flow, and self-organize to enhance entropy production. The development of Benard convection cells in a water heat gradient demonstrate simplistic operation of MEP. A direct step forward would be to explain the mechanism of the obligatory motion of molecules for life function. Motion may be mediated by operation of “action at a distance” for molecules as considered by the Einstein-Podolsky-Rosen Paradox and confirmed by JS Bell. Magnetism, electricity, and gravity are also examples of action at a distance. We propose that some variant of “action at a distance” as directed by the property of Maximal Entropy Production (MEP) underwrites biologic motion.
