Enhancing the sustainable protein extraction process from black cumin seed cake press for eco-friendly protein supplements (2025)

Abstract Finding new protein sources is essential to meet the global population’s needs. Nigella sativa (black cumin) seeds and the residual cake left after oil cold pressing contain valuable nutritional compounds, including proteins, phenolics, essential amino acids, and various bioactive compounds. In the literature, the structural characteristics and functional properties of proteins from black cumin seeds have been extensively studied. However, there are limited reports on the use

Ultrasound-Assisted Extraction of Protein from Pumpkin Seed Press Cake: Impact on Protein Yield and Techno-Functionality (2022)

Conventional solvent-based methods widely used for isolating plant proteins may deliver an unsatisfactory protein yield and/or result in protein degradation. The present study started with the optimization of pumpkin seed protein from press cake by alkaline extraction and subsequent isoelectric precipitation. Subsequently, extraction was supported by ultrasound under three conditions: ultrasonic treatment followed by alkaline extraction (US+AE), concomitant ultrasonic treatment and alkaline extr

Geotextile thickness effect on slope failure stress of encased column: 3D numerical study (2025)

The stability of uncertain earth slopes continues to pose a substantial challenge in geotechnical engineering, with an increasing necessity for effective reinforcement against various loadings. This investigation presents a 3D numerical analysis exploring the functionality of geotextile-encased stone columns (GESC) in sand slope stabilization. The research demonstrates that a GESC, optimally situated in the central region of the sand slope, enhances stability to an ideal level. Additionally, an

Study on Sediment Sorting Characteristic sand Transport Mechanism of  Engineering Accumulation Slope Erosion (2026)

 In order to reveal the sorting characteristics and transport mechanism of sediment on the steep slope Of engineering accumulation driven by runoff,three simulated runoff scour experiments were designed under The conditions of 10,20,and30 L/min from above to analyze the particle distribution characteristics of erosion sediment on the steep slope(32°) of the accumulation body of the Yangling project. The results showed that the clay and fine silt in the eroded sediment (before dispersion) increas

Evaluating the Effect of Toe Erosion on Slope Stability through the Integration of Hydraulic Model and Slope Stabilization (2024)

When heavy rainfall occurs in mountainous areas, the water level in streams rises, and the flow velocity increases, result in the enhancement of erosive capacity. As the fast-flowing water approaches the riverbanks, the stability of the riverbank slopes may reduce due to toe scour. It may further lead to the occurrence of near-bank landslides. The deposition of soil and sediment in the riverbed caused by landslides can have a major impact on the safety of the nearby residents and communities. Th

Carbonation process of commercial lime mortars vs cement-based mortars: Comparative analysis of textural differences, strength and durability (2024)

The present study analyses 5 commercially available mortars (Italian, German and Hungarian brands) under various conditions such as dry, water-saturated and freeze-thaw. Laboratory tests assessed specimens' physical properties and carbonation process 28 days after casting using EN guidelines. The workability, density, ultrasonic pulse velocity, water uptake, and strength parameters were measured. The bulk density of the studied mortars was between 1514-1840 kg/m3, indicating the variations in co

Aroma Perception of Limonene, Linalool and α-Terpineol Combinations in Pinot Gris Wine (2023)

Aromatic white wines contain monoterpenes that can alter aroma qualities based on their concentration and enantiomeric ratios. Limonene has been identified as a monoterpene that is used to differentiate monovarietal white wines. The aim of this study was to evaluate the influence of limonene on aroma perception at different enantiomeric ratios. Its interaction with linalool and α-terpineol compounds was also investigated. Eighteen model wines were created with different ratios and/or concentrati

Terpene synthase genes conferring aphid resistance via enhanced d -limonene and myrcene biosynthesis in purslane ( Portulaca oleracea L.) (2026)

Abstract Purslane is a valuable medicinal and edible plant with broad environmental adaptability, resulting in extensive germplasm diversity worldwide. This genetic diversity manifests not only in morphological traits but also in varying levels of resistance to aphid infestation. In this study, we conducted a field survey of aphid populations on 99 purslane accessions and performed controlled inoculation experiments to identify two accessions with extreme differences in aphid r

Terpene-Based Biofuel Additives (Citral, Limonene, and Linalool) with Chloroform: Experimental and Modeling Study of Volumetric and Transport Properties (2025)

In this paper, the thermodynamic properties of terpene mixtures were investigated because they represent a promising group of compounds, usually extracted from biomass, with their most notable application as fuel performance enhancers. The densities, viscosities, refractive indices, and ultrasonic speeds of sound were measured for three binary mixtures, citral + chloroform, limonene + chloroform, and linalool + chloroform, across the full composition range at temperatures between 288.15 K and 32

Shear Strength of Fiber Reinforced Recycled Aggregate Concrete (2020)

In this paper, shear strength of fiber reinforced recycled concrete was investigated. A Self Consolidated Concrete (SCC) matrix with 100% coarse recycled aggregate and different types of fibers were used in the study. Steel (3D and 5D), synthetic and hybrid fibers with a volume fraction of 0.75% were added to the concrete matrix to prepare eight beams. In addition, two beams were cast without fibers as control specimens. All beams were prepared without shear reinforcement and were tested to eval

Compressive Strength of Steel Fiber Reinforced Polymer Modified Recycled Aggregate Concrete (2021)

Demolish existing structures for better economic gains, functional and structural performance, and non-availability of land or disposal sites in nearby areas of all major cities worldwide turned as a significant reason for the crushing demolished concrete instead of using it as landfill. Research work aimed at arriving Recycled Concrete (RC) with the help of two materials, i.e. Steel Fibers (SF) and Styrene-Butadiene Rubber (SBR) latex, as additives to improve strength parameters of it. SF and S

Effect of Recycled Tyre Steel Fiber on Compressive Strength of Hollow Concrete Blocks (2026)

Abstract Concrete is the most commonly used construction material. This being most adaptable used material in buildings, cementitious material upgrading becomes extremely crucial. Destructive nature combined with brittle failure and restricted tensile strength are considered as the two main obstacles of conventional concrete. This study attempts to investigate the consequence of addition of steel fiber in different amounts in hollow concrete blocks. The main objective of the stud
