Torrefaction integrated with steam gasification of agricultural biomass wastes for enhancing tar reduction and hydrogen-rich syngas production

Steam gasification is considered as a promising technology for conversion of various biomass wastes to valuable hydrogen (H2)-rich gas products that can be applied for the sustainable production of green hydrogen and methanol. However, some inevitable problems such as high tar content and low cold gas efficiency greatly hinder its broad application. Torrefaction has been widely employed for upgrading low-rank biomass sources that favors the follow-up gasification process, resulting in low tar yield and high syngas yield. Torrefied biomass usually shows higher energy density, improved grindability characteristics, and lower O/C and H/C ratios. This research work studies the effect of torrefaction on steam gasification of corncob (CC) and rice husk (RH). The mechanisms of biomass torrefaction integrated with steam gasification are also given. Biomass torrefied at a relatively high temperature (280 °C) is more efficient to extract the oxygenated volatiles, reducing the generation of tar and particulate matters during the gasification process. The increase of torrefaction temperature resulted in an increase of H2 yield and a decrease of CO yield, corresponding to an increase of H2/CO ratio. Particularly, the H2 yield in the CC-derived syngas increased from 6.38 mmol/g (raw) to 12.01 mmol/g (280 °C), and the H2 yield in the RH-derived syngas increased from 4.33 mmol/g (raw) to 12.97 mmol/g (280 °C). Steam gasification of RH torrefied at 280 °C achieved a maximum H2/CO ratio of 2.84. After torrefaction of CC and BB at 280 °C, the tar yield of steam gasification was below 1% [gasification temperature: 800 °C, mass ratio of steam to biomass (S/B): 1]. In general, the torrefaction pretreatment of biomass at relatively high temperatures (i.e., 280 °C) favors the steam gasification process under an appropriate S/B (i.e., 1) in terms of improving the syngas quality and reducing the tar production.

Unveiling techniques and exploring the potential of Myconutraceticals: Analyzing current applications and future prospects

The escalating demand for natural, nutritionally rich food products underscores the significance of exploring the fungal kingdom, comprising yeast, lichens, molds, and mushrooms, as an abundant reservoir of nutritionalcompounds, secondary metabolites and bioactive components. This paper delves into the nutritional profiles of lichen, yeast, and mushrooms, emphasizing their role as prominent sources of myco-nutraceuticals and functional foods. The growing popularity of eco-friendly extraction techniques for mycochemicals is noted, alongside the exploration of established methods for qualitative and quantitative mycochemical analysis. Notably, studies have affirmed that the incorporation of mushroom and yeast extracts, and their derived compounds, enhances the nutritional profile of meals without compromising desirable dietary attributes. The biological health-promoting properties inherent in extracts and chemicals are also discussed. Anticipated trends the incorporation of myconutrients into functional foods and dietary supplements are highlighted. Finally, challenges hindering the optimal utilization of myconutraceuticals are scrutinized.

Histopathological Correlation Between High Endothelial Venule Neogenesis and the Tumor Microenvironment in Lung Adenocarcinoma.

The dynamic interplay between cancer cells and the microenvironment involves a wide range of intricate relationships that evolve during different stages of tumor progression. Recent attention has focused on high endothelial venules (HEVs), specialized endothelial cells in tumors with a unique cuboidal shape similar to those in lymph nodes. Previous animal studies have shown that normalization of tumor angiogenesis through anti-VEGFR2 therapy promotes HEV formation. However, few reports exist regarding the relationship between HEVs and preexisting blood vessels or interstitial fibers. In this study, we histologically examined whether tumor vascular structure correlates with HEV neogenesis. A total of 109 patients with pathological stage I lung adenocarcinoma who had undergone curative lung resection at our Institute between 2012 and 2016 were included. HEVs were identified by anti-peripheral node addressin (PNAd) staining. Immunostaining and Elastica-Masson-Goldner staining were performed on tumor sections and quantified. PNAd-positive cells were identified in 102 (93.6%) patients. Nearly all PNAd-positive cells were located within or near immune cell clusters. We investigated the correlation between microvessel structures or interstitial fibers and the number/density of PNAd-positive vessels, but no significant correlation was found. Since PNAd-positive cells were concentrated in immune cell aggregates, we focused our analysis specifically on these regions. Immune cell aggregates with abundant PNAd-positive vessels had a greater microvessel density along with by rich collagen fiber production, and displayed a more mature morphological phenotype of HEVs. The generation of PNAd-positive cells in tumors is governed by an angiogenetic mechanism distinct from that of broader tumor microenvironment. Furthermore, the accumulation of immune cells is associated with increased HEV maturation.

Identifying Factors Mediating the Carnivore Richness–Productivity Relationship Across a Precipitation‐Driven Ecotone

ABSTRACTAimPrimary productivity is an important mechanism influencing the species richness of animal taxa such as mammals. However, the factors that mediate the relationship between carnivore species richness, for example, and productivity are not well understood. We examined whether the relationship between carnivore species richness and primary productivity followed a hump‐shaped relationship and explored potential pathways by which productivity influences carnivore communities.LocationWestern Great Basin, USA.MethodsWe deployed a camera‐trap grid across a strong precipitation—and the corresponding productivity—gradient and estimated carnivore species richness using a novel application of a multisession community occupancy model. To quantify the relationship between carnivore species richness and productivity, we included the linear and quadratic effects of average annual precipitation as covariates on carnivore species richness. We fit additional community models linking carnivore species richness to vegetation and land cover variables to identify factors that mediate the relationship between carnivore richness and productivity.ResultsThe linear effect of precipitation on carnivore richness was positive and the quadratic effect was negative, supporting the hump‐shaped relationship where richness declines at the highest levels of productivity. Similarly, carnivore species richness followed a quadratic relationship with vegetation height along the productivity gradient. The relationship between carnivore species richness and proportion tree cover was positive, with limited evidence that open vegetation types in the surrounding landscape increased site‐level richness.Main ConclusionsIn addition to supporting the notion that primary productivity has a strong and nonlinear influence on local‐scale carnivore species richness, our results suggest that vegetation structure may be an important mediator of this relationship. Although future changes in precipitation and productivity due to climate change are uncertain, our results indicate that targeting areas of intermediate productivity and vegetation height, such as woodlands, may be key for conserving species‐rich carnivore communities along productivity gradients.

The Challenges of Effective English Language Teaching in Saudi Schools

Teaching English language effectively is crucial for helping English as a Foreign Language (EFL) learners communicate in the target language. Effective EFL teaching can lead to rich production and use of the language. In this study the researcher aim to explore the difficulties that EFL teachers encounter, difficulties that limit their application of effective teaching methods in Saudi schools. The researcher collected data using a questionnaire that included challenges related to various factors: the learning environment, the textbook, EFL learners, EFL teachers, and the use of technology. The participants of this study included 112 English language teachers from different cities in Saudi Arabia. The main results indicated that EFL teachers in Saudi schools face numerous challenges related to the classroom environment, the EFL textbook, the EFL learners, and technology tools in the classroom. Because the researcher explored the difficulties of using effective methods based on EFL teachers’ perceptions, the findings could assist the Ministry of Education and policymakers in investigating and overcoming the challenges EFL teachers face to enhance their application of effective methods in Saudi schools. 

Bioactive compounds and digestible starch variability of rice, maize, green gram, and soy grains with different levels of germination

SummaryGermination is a sustainable and economical process that can enhance the bioactivities of commonly consumed cereal and pulses, contributing to healthier diets. Its effectiveness in increasing bioactives depends on the germination conditions. This study examined the impact of varying germination periods (2, 4, 6, and 8 days) following 12 h of steeping on rice, maize, green gram, and soy, focusing on key bioactive compounds, including total polyphenols, flavonoids, and total digestible starch. Cereal and pulses germinated for eight days demonstrated a significantly higher (P < 0.05) total polyphenol and flavonoid content along with elevated antioxidant activity. Antioxidant activity strongly correlated to increased total polyphenol and flavonoid levels throughout the extended germination period. Moreover, the total digestible starch content (TDS) in rice, maize, and soy increased significantly (P < 0.05) because of the hydrolysis of starch molecules, while green gram showed twofold decrease in TDS, indicating the impact of germination on TDS content may differ across the type of cereal and pules. Using locally grown Sri Lankan grain varieties, such as rice, maize,green gram,and soy, this study fills the gap in existing database on the investigation of bioactive compounds and total digestible starch content, exploring the potential of germination of cereal and pulses to use in nutritionally rich products in the food and agriculture industry with a focus on sustainable food systems and healthier eating habits.

Plankton Resting Stages Distribution in Bottom Sediments along the Confinement Gradient of the Taranto Sea System (Ionian Sea, Southern Italy)

The abundance distribution and species richness of encysted plankton have been investigated in the bottom sediments of the Taranto Marine System (southern Italy) for contributing to the understanding of plankton dynamics in a confined coastal area. This confined area is characterized by four contiguous basins with different degrees of confinement. The investigation was carried out in the fall season with the aim to intercept a period of rich cyst production from the plankton before overwintering. From the analysis of a total of 36 sediment samples, from 12 sample sites, the highest abundance of cysts and species richness were registered in the confined part of the system. A total of 103 cyst morphotypes have been recognized in the whole area, with highest abundances and taxa richness in the most confined stations. These results, suggesting a benthic-pelagic exchange of living matter, more intense in confined environments than in the open sea, highlight the necessity of (i) including the analysis of sediment cyst banks in studies of plankton dynamics, and (ii) to consider the role of confined areas, where the variability of environmental conditions favours a higher planktonic biodiversity in the sediments than in the water column.

Use of microalgal-fungal pellets for hydroponics effluent recycling and high-value biomass production

Hydroponic effluent (HE), enriched with inorganic nutrients, presents a viable, low-cost cultivation medium for microalgal biomass production and subsequent resource recovery. However, downstream processing, particularly biomass harvesting, remains a critical challenge for microalgal biorefineries. Therefore, the present study explored the potential of microalgal-fungal pellets (MAFP) in HE recycling for the production of biochemical-rich biomass. The optimized fungi-to-microalgae ratio (F:A) of 1:3 resulted in 100 % microalgal pelletization within 6 h. Surface characteristics suggested that metabolically active fungi with opposite charges facilitate microalgal pelletization. Further, MAFP exhibited a packed porous structure that was resilient to shear forces and had a high capacity for nutrient uptake. MAFP cultivation in HE demonstrated complete removal of ammonia-nitrogen (NH₃-N), phosphate (PO₄³⁻), and nitrate-nitrogen (NO₃⁻-N) within 7–9 days. The produced biomass was rich in biomolecules, including lipids (18.36 ± 0.12 % TS), protein (52.06 ± 2.1 % TS), and carbohydrates (28.95 ± 0.05 % TS). Besides, the high methane potential of MAFP (SMP ≈ 502.74 ± 19.1 mL CH4 g−1 VS, and TMP ≈ 817.68 ± 12.5 mL CH4 g−1 VS) indicated its suitability for biogas production. In essence, MAFP offers efficient HE recycling and biochemically rich biomass production, advancing towards a green and circular bioeconomy.

Research on Vegetable Product Replenishment Decision Based on K-means Algorithm

The decision-making and pricing of supermarket restocking is a complex task that requires considering factors such as market demand, supply changes, and operating costs, making scientific and accurate decisions, providing customers with rich and fresh vegetable products, and promoting sustainable development. The pricing of vegetables in supermarkets generally adopts the "cost plus pricing" method, and supermarkets will formulate reasonable sales prices based on comprehensive considerations such as procurement costs, transportation costs, and operating costs. For products that may be damaged during transportation and have poor product quality, supermarkets usually offer discounts to meet customer needs and reduce food waste. This article first uses Excel software to describe and statistically analyze the data, transpose and visualize the data. Then, using the K-means algorithm in cluster analysis, the distribution patterns and interrelationships of vegetable categories and single product sales were analyzed in more detail. Finally, using Excel software, calculate the cost plus pricing for each vegetable category based on the formula "cost plus pricing=unit cost (1+cost profit margin)", and reasonable analysis is carried out according to the calculation results.This study on the calculation of cost-plus pricing for each vegetable category is of great significance to ensure the economic benefits of vegetable suppliers, improve the sustainability of agricultural production, optimize resource allocation, enhance market competitiveness, and promote the healthy development of the vegetable industry.

Hygienic assessment of dietary intake of saturated fatty acids and trans isomers of fatty acids

Introduction. An imbalance of the fat component of the diet is one of the most common violations of the population nutrition in developed countries, leading to the risk of occurring nutrition-dependent pathologies due to hyperlipidemia and dyslipoproteinemia. A special role in the formation of risk is played by an excess of medium-chain saturated fatty acids (SFA) and trans isomers of unsaturated fatty acids (TFA). Materials and methods. Actual nutrition was studied by reproduction method with three times 24-hour recall. Based on the research results, the content of SFA and TFA was calculated, and their main sources were determined. Three hundred fourteen students of the I.M. Sechenov First Moscow State Medical University took part in the study. Gender and age groups of respondents were analyzed separately. Results. The intake of SFA at the level of normal physiological needs was registered in only 7.6% of students. At the same time, 80% of respondents had a significant excess of both total fat and SFA; an adequate level of TFA intake was noted in 80% of students, and a significant excess of this indicator was registered only in 13.3% of respondents. A significant quantitative increase in SFAs was noted with the additional inclusion of processed products in the diet, including those with hidden fat. Excessive consumption of TFA is associated with the inclusion of rich confectionery products containing hydrogenated fats in the diet. Limitations. The study has age and regional restrictions: young 18–29 years people living in the Moscow region, as well as restrictions on the analyzed indicators: SFA and TFA supplied with the diet. Conclusions. A significant risk of developing nutrition-dependent non-infectious diseases is observed in 52.9% of respondents with an SFA content in the diet of more than 150% of the norm, and the maximum risk is in 13.3% of students receiving a combined excess of SFA and TFA. The results of the study confirm the need to correct the diets of students in terms of the fat component.

Cultural rice fields in the wave of climate change: a multilateral evolutionary game framework for adaptive management of agricultural heritage systems

Agricultural Heritage Systems (AHS) are pivotal in preserving rich agricultural production experience and traditional culture, as well as in maintaining biodiversity and promoting sustainable development in agriculture and rural economies. However, climate change poses significant threats to these systems, such as ecological degradation, biodiversity loss, and shifts in agricultural production patterns. This study, grounded in theories of information asymmetry and bounded rationality, constructs evolutionary game models for adaptive management of AHS under market mechanisms and government guidance. By employing stability analysis and numerical simulation with Delay Differential Equations (DDE) that consider historical delays, and through sensitivity analysis, this research delves into the strategic evolutionary outcomes of stakeholders under various scenarios. It aims to provide theoretical insights and policy recommendations for the dynamic protection and adaptive management of AHS in the face of climate change. The findings indicate that the public goods nature of AHS, alongside externalities and information asymmetry, leads to market failure. Sole reliance on autonomous actions by farmers and meteorological departments is insufficient for optimal resource allocation and effective protection. Government intervention, through regulatory and incentive measures, can effectively mitigate market failures and steer adaptive management of AHS towards efficiency and sustainability. Moreover, the study identifies key factors for adaptive management, such as enhancing stakeholders’ initial willingness to participate, reducing the costs of adapting to climate change, optimizing cooperative benefit distribution mechanisms, and increasing the profitability of resource cooperation. Sensitivity analysis of government subsidies and penalty mechanisms further reveals the complex and critical role these policy tools play in fostering stakeholder engagement. Based on these findings, the study recommends enhancing initial participation willingness, controlling transformation costs to alleviate economic burdens, optimizing benefit distribution mechanisms to boost cooperative resource profitability, and establishing dynamic subsidy and penalty mechanisms for optimal resource allocation. The theoretical and practical contributions of this research lie in applying theories of information asymmetry and bounded rationality to the adaptive management of AHS under climate change, enriching the theoretical framework in this field, and providing scientific decision-making support for policymakers. By demonstrating an effective path for AHS protection through combined government and market mechanisms in the context of global climate change, this research holds significant theoretical and practical implications for enhancing the efficiency of adaptive management of AHS, protecting, and inheriting valuable agricultural cultural heritage.

Employing a qualitative research methodology, this study draws upon a comprehensive analysis of primary and secondary legal resources.By juxtaposing the domestic legal framework with international standards and practices, this research endeavours to draw conclusions regarding the effectiveness of existing protection measures and proposes targeted reforms where necessary. The aim is to formulate tailored recommendations for enhancing Sri Lanka's GI regime through the worldwide exhaustive examination of geographical indication regimes.This research paper not only contributes to academic discourse but also serves as a practical guide for policymakers and stakeholders involved in the preservation and promotion of Sri Lanka's unique GIs. Given the urgency of addressing the challenges faced by GIs in the contemporary global trade landscape, this study underscores the importance of timely action and informed decision-making in ensuring the continued prosperity of Sri Lanka's geographical indications.

Bis(imino)pyridyliron incorporated with NO2, F and benzhydryl substituents as thermostable precatalysts for vinyl-terminated polyethylenes

The electronic and steric properties of ligands are of great importance in late transition metal catalyst mediated ethylene polymerization to tune the catalytic performance. In this contribution, strong electron-withdrawing groups—fluoro and nitro—along with benzhydryl as a steric component, were incorporated into the parent bis(imino)pyridine ligand structure to prepare a series of iron (II) chloride complexes: 2-[MeC=N{2-(Ph2CH)-4-NO2-6-F}C6H2]-6-[MeC=N(Ar)C6H2]C5H3N–FeCl2 (Ar = 2,6-Me2C6H3Fe2Me, 2,6-Et2C6H3Fe2Et, 2,6-iPr2C6H3Fe2iPr, 2,4,6-Me3C6H2Fe3Me and 2,6-Et2-4-MeC6H2Fe2Et,Me). Apart from the structural characterization of all complexes executed via FTIR and elemental analysis, X-ray diffraction analysis unveiled distorted square pyramidal geometry for Fe2Me (τ5 = 0.21) and Fe2Et (τ5 = 0.28). Upon in situ activation with either MAO or MMAO cocatalysts, all iron complexes displayed distinguished polymerization performance, especially in terms of thermo-stability. In particular, the less hindered Fe2Me exhibited high activity: 20.4 × 106 g mol−1 h−1 at 70 °C, 1.5 × 106 g mol−1 h−1 at 110 °C, and 0.6 × 106 g mol−1 h−1 at 120 °C. Whereas, the sterically more hindered Fe2iPr proved to be more productive in generating high molecular weight polyethylene (Mw up to 410.7 kg mol−1 at 70 °C). Moreover, by adjusting the reaction temperature and ligand structure, the chain termination reaction could be modulated from a high proportion of vinyl-terminated polyethylene to saturated polyethylene rich product [CH2CH(CH2)nCH3/CH3(CH2)nCH3 = 0.7/0.3–0.39/0.61], as confirmed by high-temperature 1H/13C NMR spectra. Low molecular weight vinyl-terminated polyethylenes are of significant importance in the synthesis of functional polymers and can serve as valuable additives in lubricants.

The medIeval Dashbulag settlement

The article deals with the archaeological excavation of the Dashbulag settlement located in Shamkir district in the west of Azerbaijan. The step-by-step progress of the archaeological excavations conducted in the medieval settlement of Dashbulag, the discovered production and farm buildings, household devices, numerous and diverse examples of material culture are described in detail in the article. Archaeological excavations in the village-type settlement with a planned structure were carried out in three stages in 2004, 2005 and 2014 years. Based on the observation of the sediment of the cultural layer during the archaeological excavations carried out at the settlement, which consists of one cultural layer (the thickness of the layer is 1-1.5m depending on the relief), and the analysis of the actual materials uncovered, it was established that a village-type settlement with a free-plan structure existed here in the Middle Ages. Life in the medieval village of Dashbulag, built in the 9th century, was intense until the beginning of the 13th century, gradually declined after the Mongol campaigns, and continued until the end of the 18th century with some intermittent breaks. Remains of civil and economic buildings, rich handicraft products discovered as a result of archaeological excavations in the medieval settlement of Dashbulag are evidence of the economic and farming life of the medieval inhabitants of the area, as well as pottery, metalworking, glassworking, bone-processing, etc. allows to follow the characteristics and development dynamics of art fields. The analysis of the artifacts gives reason to say that the art fields in the medieval village of Dashbulag did not lag behind, on the contrary, some regions went further than the village-type settlements.

Development and quality cum nutritional assessment based on physical properties for corn extruded snacks enriched with protein and carbohydrates: A remedy to malnutrition for society

Malnutrition is one of the century's most pressing challenges. If malnutrition is not addressed early, people may suffer from non-communicable diseases. A proper, nutritious diet is necessary to overcome diseases like malnutrition. The technology like extrusion can develop rich fortified food products by retaining high nutrition content. In this study, extrusion technology was used to develop protein and carbohydrate snacks with proper nutrition based on the physical properties of commodities by combining different ratios of corn grits, apple pomace, and mung beans. The objectives of the study focused on the development of a food product based on engineering aspects and the quality cum nutritional evaluation of the finished product that can be used as a diet to combat malnutrition. Physical properties like color, rehydration ratio, porosity, bulk density, water solubility index, texture, sensory evaluation, hardness, and crispiness were studied in detail. The energy content of protein and carbohydrates was measured for nutritional assessment using Food Data Central as a standard, provided by the United States of America Department of Agriculture. Results reveal significant variations among treatments, with the addition of apple pomace impacting bulk density, water solubility index, and color attributes. Mung bean supplementation demonstrates a direct correlation with increased hardness and influences porosity. The rehydration ratio is positively affected by apple pomace. Sensory evaluation underscores the substantial impact on color, texture, crispiness, taste, and overall acceptability, providing valuable insights for snack formulation.

Electrochemical corrosion behavior of nanostructured BCC-Al0.5CoCrFeNi0.4 high-entropy alloy in sodium chloride solution

The electrochemical corrosion behavior of Al0.5CoCrFeNi0.4 high-entropy alloy (HEA) in 3.5 wt.% NaCl solution was investigated by electrochemical measurements coupled with comprehensive characterization of its surface films. The results demonstrate that the Al0.5CoCrFeNi0.4 HEA primarily consists of (Al,Ni)-rich B2 phase and (Cr,Fe)-rich A2 phase. When subjected to electrochemical polarization, an ultrathin passive film rich in Cr is homogeneously formed on the surface. As the applied potential increases, the protective film tends to break down at the interface of two phases, followed by the preferential dissolution of B2 phase. Finally, the surface film with a triple-layer structure is formed on the HEA surface. Specifically, the inner layer and the middle layer are enriched in Cr and Fe, respectively, due to the high stability of Cr species and the selective dissolution of Fe. The (Al,Ni)-rich corrosion products are found to deposit at the outmost position ascribed to the dissolution of B2 phase.
