Robust direct solar water production by integrating interfacial evaporation and membrane distillation

Interfacial solar vapor generation (ISVG) is an important technique for producing water with a minimal carbon footprint. For customers who need a lot of water, the state-of-the-art ISVG devices are unbearable and unacceptable because of their low condensation capacity. This paper introduces a novel configuration that integrates ISVG and direct contact membrane distillation (DCMD) devices to increase the water yield. A carbon nanoparticle-based solar absorber that can collect 94.6 % of incident sunlight and has a substantial water supply capacity is employed for ISVG. For high vapor permeability, moreover, a hydrophobic polyvinylidene fluoride membrane with a moderate pore structure is adopted. The result shows that the ISVG-DCMD device has a water productivity of up to 2.71 kg m−2h−1 under 2 sun illumination. More importantly, the system has a sustainable water productivity of 2.08 kg m−2h−1 when operating in NaCl solution with a concentration of 3.5 % (w/w). This work effectively solves the problem of vapor condensation of the interfacial photothermal evaporator, offering a novel concept for scalable and robust direct solar water production.

Syngas methanation over a metal hydride catalyst: Technology performance, efficiency and economic profitability

In the last decade, biomass has been considered one of the main renewable energy sources to replace fossil fuels and consequently, biomass conversion technologies for the production of alternative fuels will play a specific role in the future energy as green biofuels for the transport sector or a power generation at small-scale distributed plants. During the thermal conversion - gasification, biomass is converted into more valuable products - syngases which could be used for biomethane production. Though, some challenges still exist related to the broad applicability of the thermal conversion of biomass to biomethane: costly short-life catalysts and a low conversion efficiency due to the high amount of carbon monoxide/dioxide in syngas.To overcome these challenges, an innovative biomethane production concept based on the plasma-assisted gasification and conversion of synthetic gases to biomethane was developed and tested, including research on the adaptability of two catalysts, magnesium nickel and magnesium nickel hydride, for raw syngas conversion. The performance of catalysts was investigated in a fixed bed type reactor using raw syngas obtained from plasma-assisted gasification.The results indicate the magnesium nickel hydride catalysts' good activity and functionality for converting carbon dioxide and carbon monoxide-containing syngas. A high conversion of 0.997 is reached. Determined that the surplus of hydrogen promotes the conversion of carbon oxides, though the volumetric concentration of methane (the maximum of 86.4 vol%) in product gas is reduced. Considering that the developed technology concept can be integrated into small combined heat and power plants, bio-waste generating plants, or decentralized areas as an additional source of renewable energy or biofuel production, the energy-mass balance and economic analysis for the optimization of 1 MWh bio-CH4 production concept was provided.

Break to Build: Isothermal Assembly of Nucleic Acid Nanoparticles (NANPs) via Enzymatic Degradation.

The intrinsic properties of RNA and DNA biopolymers emphasized by engineered nucleic acid nanoparticles (NANPs) offer accelerated development of next-generation therapies. The rational design of NANPs facilitates programmable architectures intended for regulated molecular and cellular interactions. The conventional bottom-up assembly of NANPs relies on the thermal annealing of individual strands. Here, we introduce a concept of nuclease-driven production of NANPs where selective digestion of functionally inert structures leads to isothermal self-assembly of liberated constituents. The working principles, morphological changes, assembly kinetics, and the retention of structural integrity for system components subjected to anhydrous processing and storage are assessed. We show that the assembly of precursors into a single structure improves stoichiometry and enhances the functionality of nuclease-driven products. Furthermore, the experiments with immune reporting cell lines show that the developed protocols retain the immunostimulatory functionality of tested NANPs. The presented approach enables exploitation of the advantages of conditionally produced NANPs and demonstrates that NANPs' stability, immunorecognition, and assembly can be regulated to allow for a more robust functional system.

Does agricultural factor misallocation hinder agricultural green production efficiency? Evidence from China

The sustainable development of agriculture is challenged by two major issues: increasing resource constraints and environmental pollution. Sustainable agricultural development is achievable by improving green total factor productivity from the perspective of resource allocation. To promote the green development of agriculture, this paper utilizes the SBM super-efficiency mode and thus calculates the agricultural resource misallocation index and agricultural green production efficiency index in China between 2001 and 2019. Furthermore, this paper discusses the temporal and spatial evolution characteristics of agricultural green production efficiency, using a fixed model and spatial econometric models to estimate the influence effect of agricultural resource misallocation on green production efficiency. Below are the results. First, China's agricultural green total factor productivity is growing at an impressive rate, with high efficiency in the northeast, northwest, and southeast coastal areas and low efficiency in the central and inland areas. Second, agricultural capital misallocation, labor misallocation, and land misallocation all negatively impact agricultural green production efficiency. Accordingly, the misallocation of agricultural factors will hamper the growth of agricultural green production efficiency in this region and also in the surrounding areas. Third, the indirect impact on the own agricultural green production efficiency exceeds its direct impact on neighboring regions' efficiency. Fourth, the mechanisms are the upgrading of agricultural industry structure and green technology innovation. According to the findings, reducing resource misallocation can substantially enhance agricultural green productivity, which is an imperative step in addressing agricultural green production. Hence, policies should be formulated that highlight the regional allocation of agricultural production factors and green production-oriented concept of agricultural production. Also, the government should promote the transformation and upgrading of the agricultural industrial structure, as well as the application of green agricultural technologies.

MODERN INTERIOR ART OBJECTS: CLASSIFICATION AND CREATION FEATURES

In recent years, there has been an increasing interest in art-design that is a combination of art and design where the conceptual component prevails over the utilitarian value of the object. The works of art-design reflect the author’s artistic concepts and combine aesthetic expressiveness, artistic design and a certain functional load. The objectives of this study are to make a classification of modern interior art-objects and to determine the role of modern industrial equipment in the process of creating designated creative works. The methodology of this work based on the application of empirical and theoretical research methods. The empirical methods, namely experiment, comparison and observation, when studying the characteristics of the manufacture of these creative compositions, are fundamental. To summarize the practical experience and update the curriculum applied theoretical research methods, namely analysis, synthesis and forecasting. The results of the research support the idea that art-objects can be classified: by composition (frontal, three-dimensional, deep-spatial); in terms of components (modular, similar, heterogeneous); in artistic and figurative direction (abstract, associative, naturalistic); by nature of interaction with humans (interactive and static); by materials (wooden, polymeric, metal, glass, mirror, with fabric or combination of several materials in one work); by function (creation of compositional accents or compositional dominant in the interior, identification of separate zones in space, creation of a special artistic-imaginary system in the interior). The analysis of numerical examples of the introduction of art objects in the general design of the object-space environment revealed the criteria that influence the perception of the identified compositions by man: the figurative and stylistic conformity of the art-object to the overall interior design. In this aspect becomes important the question of forming a coherent harmonious space; the compositional arrangement of art-objects in a object-space environment, which depends on the author’s concept, architectural planning and spatial-spatial features of the interior. It was revealed that the creation of art-objects is based not only on the knowledge of the composition, but also on the understanding of the features of modern industrial equipment, which is used in the creation of these objects. To make the interior art-object it is necessary to follow certain stages of the work, namely: analysis of the works of predecessors, formulation of the concept, sketching and the production of the object. To produce elements of an art-object it is necessary to create a computer model of that object; to write a control programs for CNC machine tools production of the details of an art-object in the material; to decorate the surfaces of elements. The present results are significant that the use of innovative technical means requires the ability to work in special graphic computer programs and to understand the physical, artistic and aesthetic properties of materials. The use of CNC machines improves the quality of the compositions and opens new horizons in the field of implementation of the most daring creative concepts and the use of different materials. We conclude that the use of industrial equipment in the process of art-objects creation contradicts the concept of manual production of a work of art-design, but the machine is just a tool in the hands of the artist, whose use doesn’t offset knowledge of composition, understanding of combinatorics. Without professional training and original artistic design, no industrial equipment is able to produce a unique art object.

Waste heat recovery system for marine engines optimized through a preference learning rank function embedded into a Bayesian optimizer

Waste heat recovery is a proven process to improve efficiency on engines and meets current necessities of the maritime industry. Since January 1, 2023, already built vessels must meet the energy efficiency indicators known as EEXI and CII. Aiming to reduce fuel consumption and mitigate pollution emissions, a novel waste heat recovery system composed of steam Rankine cycle, organic Rankine cycle, thermoelectric harvesters and desalination is presented. High, medium and low-grade waste heat from exhaust gas, jacket water, lubricating oil and engine block radiation are targeted for recovery. Performance assessment of each subsystem when implemented on a real case study 6-cylinder medium speed marine engine is analyzed. The equivalent electricity production concept was used for the assessment of the desalination subsystem. The proposed system effectively recovers waste energy, offering economic benefits, reducing pollution and satisfying the daily demand of fresh water. Also, optimal states of the waste heat recovery are provided via Bayesian optimization, which requires an evaluation function for the system to be optimized. However, this function is not available and cannot be straightforwardly established, since the quality of waste heat recovery depends on some indicators with a trade-off among them. Hence, a preference learning procedure that exploits expert knowledge is proposed to induce a function of this kind from those indicators in order to be embedded into the Bayesian optimization procedure afterward. Applied to the case study engine, a fuel consumption reduction of 15.04% is achieved. Fuel savings lead to an improvement in energy efficiency indicators, achieving a reduction of 6.98% on the EEXI and a 13.85% on the CII.

National Wealth as an Economic Category

National wealth is one of the most general economic categories and an integral indicator for assessing and comparing the economic potential and capabilities of different countries. The calculation of such important macroeconomic quantities is based on the system of national accounts. In the economic literature, the term wealth refers to the sum of certain elements. In the economic literature, the term "wealth" refers to the sum of certain elements. In this sense, "wealth" is the object of economic science and statistical research. Country, nation, people, social wealth - these categories emerged with the formation of economic science. The first mention of the category "national wealth" in foreign literature is associated with the works of the classical economist W. Petty. In his search for the source of wealth, the author quantified the economic events of his time. In 1664 the scholar calculated the national wealth of England. Two concepts have emerged: national wealth is regarded as a certain fund held by a country in a certain period of time, or as recurrent income, a certain flow of products processed and used by the state, of the country over a certain period of time. The second concept dominated 19th century science. In our view, the definition of national wealth as a certain flow over a certain period of time is more characteristic of the concept of national income or gross product. For a scientifically sound and legitimate characterization of the concept of national wealth it is necessary to combine these two approaches. Only from the middle of the 20th century onwards. National wealth is identified with the accumulated stock of tangible and intangible assets. All elements of national wealth have a material composition, i.e. represent the material wealth of society. But on the wave of scientific and technological progress, information played a big role, in the mid-twentieth century the economy transformed from industrial to neo-industrial, and intangible elements were included in national wealth: human capital and information. If we compare countries by the level of national wealth, it is known that natural resources prevail in the structure of national wealth of low-income countries, and human potential prevails in high-income ones. In order to achieve a certain level of socio-economic well-being, most researchers believe that forms of international division of labor and organization are necessary to enable less developed countries to change the proportions of national wealth. and increase the proportion of human potential. Keywords: Wealth, national wealth, national wealth as an economic category.

Heating greenhouses by light: A novel concept for intensive greenhouse production

High-tech greenhouses are characterised by high yields and high energy consumption. Current trends towards expanded use of supplemental lighting further increase the intensity of crop production and energy use, and it is expected that the availability of light-emitting diodes (LEDs) will accelerate this trend. At the same time, an increase in greenhouse lighting reduces the heating energy needed from the heating system. This study presents a novel concept for greenhouses, where both lighting and heating are derived exclusively from lamps. Such greenhouses can be highly efficient, as light is used both for crop growth and for heating. If the electric grid is based on renewable sources, such greenhouses can also be carbon-neutral and fossil-free. By using model simulations for a tomato greenhouse in the Netherlands, it was found that such greenhouses could be realised by employing a heat storage system with a heat storage capacity of 2 MJ m−2 and LEDs with a power capacity of 150 W m−2 and a photosynthetic photon flux density (PPFD) of 450 μmol m−2 s−1. The greenhouse heated by light was predicted to have 44% higher yields and 60% higher energy inputs than a reference greenhouse, equipped with a boiler and LEDs with a PPFD of 200 μmol m−2 s−1. This result was part of a general trade-off that was found between yield and energy efficiency. This exploration helped identify avenues for further improvement of the energy efficiency of greenhouses heated by lamps, highlighting their promise as a potential new direction in greenhouse intensification.

FINANCIAL PRODUCTION IN ISLAM

Worship includes every human movement in life, and accordingly a person’s quest for gain is worship, and he is rewarded for it as long as he adheres to what he is obligated to do in it. The research has been called just earning; Because the meaning of justice is a comprehensive meaning to address many things, it is more general from the word of the halal or crusher, and human must be amounting to himself and with others, Allaah says: you remember.
 In my research, (production financing in Islam) I dealt with some of the production issues from a Quranic perspective by explaining its importance, responsibility, objectives, controls and financing, explaining the difference between the concept of production and the concept of earning, then the production controls and production financing in Islam, then the conclusion of the chapter was with a statement of the alternatives in investment and financing by participation. in the capital. For this reason, I extrapolated the verses in which the conditions of earning are mentioned in the Noble Qur’an, using the inductive method, then I interpreted the verses and explained hadiths, criticism and deduction. Using the analytical method, then I showed the teachings to which the verses guide us, which must be applied in dealing with people through the applied approach.

A Review of Sustainable Pillars and their Fulfillment in Agriculture, Aquaculture, and Aquaponic Production

Focusing on new food production methods and sustainable pillars’ accomplishments has changed the definition of sustainable pillars themselves. Moreover, some general characteristics of the main pillars can be redefined in separate dimensions to better explain their positive sustainable impacts. Therefore, the main objective of this research is to redefine the sustainable pillars linked to food production and review the most important cultural and technological sustainability impacts they have, in addition to the three classic pillars: economic, social, and environmental sustainability. Cultural and technological sustainability are increasingly important complements to the traditional sustainability concept. Furthermore, new food production technologies and systems are influenced by ancient production methods, as well as by profitable crop selection. Traditional agricultural and aquaculture production in relation to more recent aquaponic production concepts are still a major part of global food security, but the better usage of waste materials or residues generates a more favorable agroecological impact. In conclusion, constantly redefining the sustainable pillars in the context of sustainable food production methods and proving the viability of their general production impacts is important.

Mechanisms for industrial coordination of “new” tourism regions: The case of Dagestan

The tourism industry that has developed in several constituent entities of the Russian Federation in the last three years contributed to the growing interest in its architecture. The article identifies the driving force behind change in the structure of the industry in the “new” tourism regions. The methodological basis of the study combines institutional theory (principally, the theory of transaction costs underlying the counterparties coordination mechanisms) and the concept of tourism product. The research methods of comparative analysis and in-depth interviewing were applied. The empirical data were retrieved from 29 interviews with representatives of the tourism business conducted between October, 2021 and November, 2022 in three constituent entities of the RF. The study demonstrates that the hybrid coordination mechanisms are most common in the “new” tourism regions. For instance, in Dagestan, the tourism product is created within vertical networks that unite partners at different stages of the value chain, while the selection of counterparties and the exchange of resources for this product to be produced take place within horizontal networks that enhance the efficiency of the industry. At the same time, as the tourist flow intensifies, there emerge some trends towards hierarchization (dealing with contractors as part of the firm) and a decrease in the role of horizontal networks in the functioning of the industry. Based on the results obtained, we can conclude that the process of hierarchization will be continued, while the potential associated with entrepreneurial networks is not used actively enough by both the business itself and the state.

Konsepsi Dasar Ekonomi Mikro Berbasis Paradigmatik Hukum Ekonomi Syariah

Islamic economics is believed to be a science that exists as an alternative to conventional economics which has failed to develop human welfare in general. Conventional economics is considered to have been born out of a vacuum and there is no role for Islamic scholarship in its historical development, as stated by Schumpeter in his great gap. Scientists emphatically argue that Greco-Hellenistic scholarship reaches the hands of modern European scholars today through the kindness of the hands of Muslims who modify it and add value to it, as stated by Mehdi Nakosteen. Therefore, it is important to explore the existence of conventional economic conceptions in classical Islamic literature. To prove that Conventional Economics does not depart from a vacuum and that Islamic Economics is part of the history of the birth of conventional economics. In several classical Islamic sources, several basic concepts of conventional economics are found which are not only similar but also exactly the same as a whole. In classical Islamic literature, basic concepts such as unlimited human needs, the concept of value, the concept of production, the theory of supply and demand, the mechanism of market prices and others are found. This provides evidence for us that Islamic economics is not a "new" thing that has never existed in the history of the development of science. Even the science of Islamic Economics existed even before the birth of conventional economics.

Analysis of Small Modular Nuclear Reactor Construction on the Moon

The current goals of lunar exploration include the return of humans to the Moon for scientific activities and the ability to implement lunar in-situ resource utilization (ISRU) for propellant production and construction. Both goals will consume power and one option to meet these power requirements are small nuclear reactors (Kilopower or Pylon). Launching these might not be beneficial in the future as the lunar infrastructure develops and the power requirements grow. The possibility of lunar independence from Earth in terms of ISRU must be considered. This paper discusses the materials used in each nuclear reactor including the fuel, reflector, working fluid, etc. along with lunar abundancy of each element used in these materials. Since no lunar ore mining or material production concepts were found, a review of Earth-based mining and production methods for each material were described. As a result, furnaces, mills/crushers, and fluidized bed reactors can be utilized for various processes in material production. Other processes including leaching, flotation, etc. will need their own machines. In the future, designing multifunctional furnaces and ball mills or crushers can be considered since this will simplify the lunar infrastructure and can be advantageous in the long run decreasing Earth dependency and cost.
