Briquette Production from Vineyard Winter Pruning Using Two Different Approaches

Worldwide, different strategies are being developed in order to ensure optimum conditions for the development and growth of economic competitiveness, as well as for increasing the quality of life and environmental protection. All these strategies are closely linked to the development and modernization of systems for producing energy from clean and renewable sources. In this context, the present paper presents the results of research regarding the evaluation of the sustainability of briquette production using biomass resulting from vine winter pruning as the raw material. An analysis of the scientific literature indicates that nearly 8 Mt of biomass would result from the over 7.4 million hectares of vine plantations in the world, biomass that could be valorized through densification in order to produce solid biofuels with a lower calorific value of more than 17 MJ/kg. This study examines the production of briquettes from vineyard winter pruning with consideration of two types of densification technologies: baling and natural drying of the tendrils, and collection, shredding, and artificial drying of the lignocellulose debris. The quality indices and energy consumption and energy efficiency of the briquettes were evaluated to determine their feasibility as an alternative fuel source. When designing the scientific endeavor, the following aspects were considered: defining the aim and objectives of the research; designing the research algorithm; collecting, preparing, and conditioning the biomass; conducting a chemical analysis of the briquettes; and evaluating the energy consumption and energy efficiency for producing the briquettes, taking into account two drying methods (natural and artificial drying). In the meantime, some specific laboratory equipment was designed and built for the artificial drying of biomass, evaluation of mechanical durability, measurement of energy consumption, etc. Analysis of the experimental data has led to the conclusion that the agricultural waste from vine pruning can constitute an important and sustainable source of energy in the form of briquettes that fulfill most of the requirements imposed by international standards.

Introducing high-density growth twins in aluminum alloys by laser surface remelting via templated nucleation of grains

It is difficult to generate coherent twin boundaries in bulk Al alloys due to their high intrinsic stacking fault energy. Here, we report a strategy to induce high-density growth twins in aluminum alloys through the heterogeneous nucleation of twinned Al grains on twin-structured TiC nucleants and the preferred growth of twinned dendrites by laser surface remelting of bulk metals. The solidification structure at the surface shows a mixture of lamellar twinned dendrites with ultra-fine twin boundary spacing (∼2 μm), isolated twinned dendrites, and regular dendrites. EBSD analysis and finite element method (FEM) simulations have been used to understand the competitive growth between twinned and regular dendrites, and the solidification conditions for the preferred growth of twinned dendrites during laser remelting and subsequent rapid solidification are established. It is shown that the reduction in the ratio of temperature gradient G to solidification rate V promotes the formation of lamellar twinned dendrites. The primary trunk spacing of lamellar twinned dendrites is refined by the high thermal gradient and solidification rate. The present work paves a new way to generate high-density growth twins in additive-manufactured Al alloys.

BNIP3-mediated mitophagy boosts the competitive growth of Lenvatinib-resistant cells via energy metabolism reprogramming in HCC

An increasing evidence supports that cell competition, a vital selection and quality control mechanism in multicellular organisms, is involved in tumorigenesis and development; however, the mechanistic contributions to the association between cell competition and tumor drug resistance remain ill-defined. In our study, based on a contructed lenvitinib-resistant hepatocellular carcinoma (HCC) cells display obvious competitive growth dominance over sensitive cells through reprogramming energy metabolism. Mechanistically, the hyperactivation of BCL2 interacting protein3 (BNIP3) -mediated mitophagy in lenvatinib-resistant HCC cells promotes glycolytic flux via shifting energy production from mitochondrial oxidative phosphorylation to glycolysis, by regulating AMP-activated protein kinase (AMPK) -enolase 2 (ENO2) signaling, which perpetually maintaining lenvatinib-resistant HCC cells’ competitive advantage over sensitive HCC cells. Of note, BNIP3 inhibition significantly sensitized the anti-tumor efficacy of lenvatinib in HCC. Our findings emphasize a vital role for BNIP3-AMPK-ENO2 signaling in maintaining the competitive outcome of lenvitinib-resistant HCC cells via regulating energy metabolism reprogramming; meanwhile, this work recognizes BNIP3 as a promising target to overcome HCC drug resistance.

Effect of Tax Policy Changes on Corporate Investment Decisions in Saudi Arabia

Purpose: The aim of the study was to assess the effect of tax policy changes on corporate investment decisions in Saudi Arabia. Methodology: This study adopted a desk methodology. A desk study research design is commonly known as secondary data collection. This is basically collecting data from existing resources preferably because of its low cost advantage as compared to a field research. Our current study looked into already published studies and reports as the data was easily accessed through online journals and libraries. Findings: The study indicated that reductions in corporate tax rates generally lead to increased investment by companies. Lower taxes can free up funds that businesses then use for capital expenditures, research and development, and expansion projects. Conversely, higher tax rates may discourage investment, as they reduce after-tax profits and make certain projects less economically viable. However, the relationship between tax policy and investment decisions is complex and can vary depending on factors such as the overall economic environment, industry dynamics, and the specific details of the tax changes. Overall, though, there is evidence to suggest that tax policy plays a substantial role in shaping corporate investment behavior. Implications to Theory, Practice and Policy: Pecking order theory, agency theory and neoclassical investment theory may be used to anchor future studies on assessing the effect of tax policy changes on corporate investment decisions in Saudi Arabia. Policymakers and corporate leaders should collaborate to design tax policies that align with strategic investment objectives, fostering economic growth, innovation, and market competitiveness. The findings from research studies on the effect of tax policy changes on corporate investment decisions can inform evidence-based policymaking aimed at optimizing tax frameworks for economic resilience and dynamism.

DEVELOPMENT STRATEGY FOR THE SCIENTIFIC EDITION “RUSSIAN JOURNAL OF EDUCATION AND PSYCHOLOGY”

Background. Russian scientific journals joined the international market of scientific publications quite late, which actualises the development of a strategy for entering this market and complicates the realisation of the strategy as such in the environment of tough competition on the part of experienced and stable players thereof. Purpose. The purpose is to elaborate a strategy for the development of the “Russian Journal of Education and Psychology” for its introduction to the international market. Materials and methods. The research sources are represented by statutory acts, statistical materials and results of the author’s empirical research. The research is based on the systemic approach; the strategy of the journal is based on the ideas of the positioning school; the main method of business planning is economic analysis. Results. The growth of competition in the domestic market, along with the gradual approximation of the Russian scientific journals evaluation system to the global practice and the universal quality criteria, proved to be the conditions inspiring the change in the strategy of the scientific edition “Russian Journal of Education and Psychology”. The detailed analysis of the internal and external environment of the journal made it possible to form a self-contained range of strategic alternatives among which the entry to the international market was the most appropriate way to meet the objectives of the publishing house and the interests of the proprietor (who is also the project customer). Securing the journal’s work in accordance with the requirements of the international scientometric databases, for its inclusion in the Scopus and (or) Web of Science, became a new strategic goal of the journal. The new goal changed the concept and mission of the journal with regard to the customer’s wish to preserve the edition’s traditional values. Changes in marketing and peer reviewing were identified as the main transformation areas for which new functional strategies were developed. The overall project plan envisages the solution of other targets as well, but it is the tasks connected with the journal distribution and the change in the work of the editorial board and in the business aspects of reviewing that became extremely significant in terms of their timing and involved financial costs. The project team comprising current employees is supposed to cope with possible risks with respect to project completion time, while the financial resources of the publishing house will allow it to overcome the financial risks of the project without any assistance. Even in case of failure to achieve the strategic goal, due to its high risk, the journal’s key performance indicators will be improved through the increased share of high-quality articles; by optimising and tightening the review process, active promotion of the journal in the national and foreign markets; by attracting a numerous audience (authors, readers) and expanding the number and diversity of stakeholders.

Crystal organisation and material properties of Chama and Glycymeris myostraca and shells

Movement of bivalve hard and soft tissue requires muscular action. Despite diverse bivalve lifestyles and living environments, the myostracum, a specific hard tissue formed where muscles attach to the shell, appears similar in structure for species of many bivalve orders.We investigated myostracal and non-myostracal, valve, microstructure, texture and material properties of Chamidae and Glycymerididae species with electron-backscatter-diffraction, laser-confocal and backscatter electron imaging and nanoindentation testing. Chamidae and Glycymerididae follow different lifestyles and live in distinct environments. Chamidae are cemented to substrate and live in wave-swept, shallow, waters. Glycymerididae dwell in calm water and burrow into sandy/muddy sediment.We found that myostracal aragonite of all investigated species has a crystal assembly pattern that reflects crystal growth through growth competition. Aragonite is extensively twinned in the myostracum and non-myostracal, valve, layers, not in the calcitic ornamentation. For myostracal aragonite, we found cyclic twinning, for non-myostracal aragonite the twinning was polysynthetic or polycyclic. We show how twinning and crystallographic texture are transmitted between myostracal and non-myostracal, valve, layers. Relative to non-biological aragonite, myostracal and non-myostracal, valve, indentation elastic modulus is reduced by 10–15 % and 15–20 %, respectively; myostracal and valve hardness is increased by 15–20 % and 5–10 %, respectively. Comparing modulus and hardness between aragonitic microstructures, we found that, relative to other microstructures, myostracal modulus is increased by 5 % and myostracal hardness by 15 %. Hence, the myostracal material shows a unique and specific microstructure, texture, modulus, and hardness that might be necessary for muscle attachment to enable the lifestyle-controlled requirements posed onto the organism.

Effect of microbial growth and electron competition on nitrous oxide source and sink function of hyporheic zones

The hyporheic zones (HZs) are key sites of the production of nitrous oxide (N2O), a potent ozone-depleting greenhouse gas. Denitrification is the primary process of N2O production in HZs, including four reduction steps (NO3−→NO2−→NO→N2O→N2). Electron competition occurs between the four reduction steps and can significantly impact the production of N2O. However, denitrification was typically considered as simplified two step reactions for investigating the release of N2O, neglecting the electron competition among the four-step reactions. Moreover, the N2O production/consumption patterns are regulated by both hydraulic and biogeochemical conditions in HZs. Dynamic microbial growth cannot only mediate the biogeochemical reactions, but also change hydraulic properties spatiotemporally by bioclogging. But microbial growth is rarely considered for investigating N2O dynamics of HZs. To assess these effects on hyporheic N2O dynamics and source-sink function, we establish a novel numerical model of N2O dynamics of HZs, coupling porous flow, reactive transport, electron competition, microbial growth and bioclogging. The results show that the weak electron competitiveness of N2O reductase results in a less allocation of electrons to the N2O reduction process, particularly in situations with limited carbon sources, thus increasing the release of N2O into the rives. Microbial growth significantly influences N2O release from HZs into rivers, increasing by more than two orders of magnitude on average compared to the model neglecting microbial dynamics. In contrast to the classical knowledges that HZs in coarse sediments tending to short residence time cannot act as sources of N2O, dynamic microbial growth obviously increases the potential for N2O release from HZs in coarse sediments to the rivers. The global Monte Carlo regional sensitivity analyses indicate that microbial biomass is the most critical factor determined the hyporheic source-sink function for N2O, followed by carbon oxidation rate and residence time. These are significantly different from previous knowledge that the residence time and oxygen/nitrogen uptake rate are the most sensitive parameters, which may lead to misunderstanding of the key controlling factors of N2O release from HZs. In addition, we propose a new Damköhler number (DaO2∗) of dissolved oxygen by multiplying the classical DaO2 with a dimensionless microbial modification factor for identifying N2O source-sink function of HZs, with DaO2∗ < 1 for N2O sink, while DaO2∗ > 1 for N2O source.
