Technological Aspects of Bridging the Gap Between Cell-Based Food and Conventional Meat

Cell-based food, including cultured meat, introduces an innovative complement to our dietary options, introducing cellular agriculture and tissue engineering on the meat market together with traditional livestock farming. Originating from medical tissue cultivation techniques, this approach is now tailored for food production, prioritizing cost-effectiveness, palatability, and resource efficiency. As technology strives to efficiently upscale production, consumer acceptance stands as a key factor in adopting this new protein source. This review explores advances in cultivating muscle and fat tissues in vitro, emphasizing the importance of achieving muscle maturity, innovating scaffolds, and optimizing media composition to closely replicate the qualities of meat. It also addresses quality assessments of cultured meat based on its texture, nutritional content, and flavor. A concise examination of consumer perceptions reveals that acceptance is influenced by a blend of cultural, psychological, and social factors, balancing the positive potential outlook on cultured meat’s benefits for society, the environment, and animal welfare against concerns about its unnaturalness, uncertainty, and safety. Demographic trends suggest higher acceptance among younger, well-educated and urban individuals, contrasting with reservations from those more familiar with the traditional meat sector. Addressing these varied viewpoints is essential for a better understanding of public acceptance if cultured meat is effectively introduced into our future food systems. As media interest in this alternative is still high, aligning technological developments with consumer expectations is crucial for the potential market introduction of cultured meat.

This review conducts a comprehensive literature survey on the application of biomimetics in the design of soil-engaging components. The focus is on performance optimization in regard to the following three aspects: draught reduction, anti-adhesion, and wear resistance. The mechanisms of various biomimetic soil-engaging components are systematically explained. Based on the literature analysis and biomimetic research, future trends in the development of biomimetic soil-engaging components are discussed from both the mechanism and application perspectives. This research is expected to provide new insights and inspiration for addressing related scientific and engineering challenges.

A comprehensive combustion, performance, and environmental analyses of algae biofuel, hydrogen gas, and nano-sized particles (liquid-gas-solid mix) in agricultural CRDI engines

The present research encompasses the utilization of TiO2 nano particles with enrichment of H2 (10 lpm) with Chlorella Emersonii Methyl Ester (CEME) on an agricultural-based CRDI engine. CEME20 (20% chlorella emersonii methyl ester blended with 80% mineral diesel) is employed for the tests. The nanoparticle concentration is limited to 50 ppm which has been considered according to O2 concentration in biodiesel. Experimentation revealed that, with hydrogen gas and TiO2 nanoparticles, the BTE and BSFC were improved significantly. At full load conditions, BTE is enlarged by 7.3%. In addition, there is a simultaneous decrease in HC and CO emissions (by about 36.3 and 40.9% respectively) for algal biofuel blends, while NOx emissions increased by 27.3% with respect to mineral diesel. 5.1% and 6.5% increase in combustion characteristics (79.8 bar combustion pressure and 89.2 J/°CA heat release rate)were observed for the CEME/H2/TiO2 blend which could be attributed to effective combustion of hydrogen and catalytic combustion activity provided by TiO2 nano additives. CEME/H2/TiO2blend recorded maximum Mass Fraction burnt (MFB) (74.7%) as well as lowered PSD (Particle size Diameter) profile (34.8 nm @ 0.29 E+08 dN/dlogDp (#/cm3)) at full engine load condition indicating the presence of H2 and nano additives which has influence over the combustion.

Advances of natural fiber composites in diverse engineering applications—A review

This paper emphasizes the significant usage of natural fiber as a reinforced composite in the potential engineering field. Mechanical, civil, textile, agricultural, and other engineering sectors have already initiated the utilization of natural fiber in their multiple fields. After going through some processes like treating chemically and synthesizing them accordingly, natural fiber composites are prepared for respective implementation. Unlike other types of composite materials, natural fiber composites have some unique properties like recyclability, adaptability, environmental safety, and easy persuasion. On the other hand, different types of naturally oriented fiber like jute, cotton, silk, linen, hemp, etc. have almost the same kind of mechanical, thermal, and chemical features as traditional composite materials. Additionally; automobile, marine, aerospace, medical, and recreation industries claim a significant realm in this type of material kingdom. Though moisture problems, fiber swelling, and safe reusability are threatening for natural fiber-reinforced composites, more research will certainly reduce these problems. Researchers play a significant role in the permanent solution of different applications of natural fiber composites in every engineering sector.

A practical equation for predicting saturated hydraulic conductivity of fine-grained soils

The saturated hydraulic conductivity (ks) of soils plays a crucial role in various agricultural and environmental engineering applications, particularly in relation to pollution prevention and water migration. Firstly, the traditional Kozeny-Carman (KC) equation, which are commonly used to estimate ks, has limitations in predicting ks for different types of fine-grained soils based on the analyses of permeability test data in the literature. Secondly, to tackle this issue, a modified KC equation was proposed by introducing an expression for the shape parameter and establishing a relationship between the tortuosity equation and the plastic limit. Additionally, the validation of the proposed equation was conducted using ks values of 25 fine-grained soils obtained from other sources. Finally, a comparison was made with the four commonly used ks models to evaluate its performance. The results indicate that the proposed equation demonstrates a relatively high coefficient of determination and a low root mean square error. This suggests that the proposed equation has the potential to accurately assess ks for fine-grained soils. The predictions for ks using the modified equation showed good agreement with the experimental data mentioned in the literature.

The role of russian scientific schools in the formation and development of mechanization and electrification for agriculture in Russia (1920–2023 years)

The article examines the process of formation and development of scientific agroengineering schools and their role in the creation of mechanization and electrification of agriculture in Russia in 1920–2023. The logic of the conducted research required the definition of time periods (pre-war 1920–1940); (post-war 1945–1990); (present 1991–2023). In the pre-war period, a powerful foundation and foundations for the development of agroengineering science were laid. The development and implementation of agricultural machinery has come to the fore. The post-war period is characterized by the rapid development of all spheres of agricultural mechanization and agricultural engineering; the creation of new agricultural machinery, the development of research methods, new more efficient design technologies, the consolidation of efforts of representatives of agroengineering science, testers and manufacturers of equipment. In the early 1990s, a significant reorganization was carried out in the engineering and technical sphere of the Russian agro-industrial complex. he Russian Academy of Agricultural Sciences has been established. In October 2013, as part of the reform of the Russian Academy of Sciences, the State Academies of the Russian Academy of Sciences and the Russian Agricultural Academy of the Russian Academy of Sciences merged. In 2016, the Federal Agency for Scientific Organizations set a course to streamline the network of subordinate scientific organizations, create institutes and federal research centers based on similar topics. The followers of Academician V. P. Goryachkin work in these scientific institutes and centers. They develop the great scientific heritage left by him and, using the best domestic traditions, raise agroengineering science to a higher level.

Influence of Hydrogen induction on performance and emission characteristics of an agricultural diesel engine fuelled with cultured Scenedesmus obliquus from industrial waste

The use of microalgae in waste water treatment has been recognised as crucial for managing and treating effluent from industrial sources. Present study used Scenedesmus obliquus (SO) strains in industrial waste cultured medium, grown algae were collected and dried, further with dried mass to algae bio fuel by transesterification process. Four fuel blends were created by adjusting the SO concentration from 10% to 40% by volume. Then SO blend was examined with impact of hydrogen induction on compression ignition engine. The addition of H2 to SO biodiesel enhances its net calorific value because of its high calorific content.Adding H2-inducted SO proportion to diesel reduces HC, NOx, and CO levels, with a negligible performance dip. At full loads, SO40 showed a significant improvement in emission levels, with a 19.81% reduction in NOx, a 51 ppm drop in HC and 1.146% dropobserved in CO compared to diesel. For the SO10 mix, BTE and BSEC were found to be 2.86% and 2103.77 kJ/kW-hr, respectively, superior to other SO blends. Subsequently, it is of crucial significance to acknowledge the significance of the potential those microalgaeprovides for the production of sustainable energy through the reprocessing of industrial effluents.

Human-centered design in the development of innovative technology for the food processing medium, small and micro enterprises (MSMEs) in Uganda

Taking account of end-user perspectives is crucial in the design and development process to ensure successful technology adoption considering the evolving customer demands. This study utilized the user-centric Human Center Design (HCD) framework to re-develop food processing equipment, specifically pulpers and pasteurizers, previously developed by the Department of Agricultural and Biosystems Engineering (DABE) of Makerere University. The study implemented several interventions to augment the adoption of processing equipment among MSME agro-processors in Uganda. This included development of modified pasteurizers (biomass and electrical) and pulpers, development of user manuals, and training of processors on the use of equipment. All interventions were designed with a focus on the needs and preferences of the end users. This study demonstrates how HCD can be used to develop food processing equipment that addresses the dynamic needs of micro, small, and medium-scale agro-processors in form of production capacity and cost of ownership. The study findings can influence large-scale research and policy toward the production and adoption of user-centric food processing equipment, which in turn can provide agro-processors with increased livelihoods and reduce the major challenge of post-harvest losses.
