Functional and Technological Characterization of Microorganisms Isolated from Wet Coffee Fermentation in Brazil: A Multivariate Approach for the Selection of Promising Isolates

Abstract Coffee fermentation is a stage of wet coffee processing carried out by microorganisms. This study aimed to characterize microorganisms isolated from wet coffee fermentation by their enzymatic potential and to evaluate how different stress conditions affect the selection...

Mixture design optimization of Nile tilapia (Oreochromis niloticus) pâté formulated with mechanically separated meat: integration of sensory acceptance and formulation cost

Abstract A significant portion of aquatic food industry by-products is still directed to low-value applications, even though they have technological potential for food products, such as mechanically separated meat (MSM) in emulsified products. This study optimised theformulation...

Analytical Synthesis and Closed-Form MZI Mapping of FIR Filters for Chromatic-Dispersion Compensation

This dataset contains the simulation data, filter coefficients, and figures supporting the manuscript "Analytical Synthesis and Closed-Form MZI Mapping of FIR Filters for Chromatic-Dispersion Compensation," submitted to the IEEE Journal of Lightwave Technology (2026). The dataset...

Field Scale Geoenvironmental Performance of Steelmaking Slag and Soil Mixtures in Unpaved Road Layers

Abstract The reuse of steelmaking slags in road engineering requires an integrated evaluation of their geotechnical and geoenvironmental performance under real exposure conditions, particularly because of the high alkalinity commonly associated with these materials. This study in...

Supply-chain risks and resilience mechanisms relevant to military aviation: a systematic review of defense and aerospace literature

Purpose This study synthesizes defense and aerospace supply-chain literature to identify and organize risks and resilience mechanisms relevant to the industrial, maintenance, and sustainment systems supporting military aviation, with particular attention to aircraft availability...

Long-term evolution of Fe oxyhydroxide mineralogy and potentially toxic element partitioning in mining-impacted sediments of the Lower Doce River fluvial–estuarine system

Abstract The collapse of the Fundão dam in southeastern Brazil released large quantities of Fe-rich tailings into the Doce River basin, generating a long-term legacy of mining-derived sediments enriched in potentially toxic elements (PTEs). Although Fe oxyhydroxides are recognize...

An Alternative Test to Evaluate the Assistance Provided by Back-Support Exoskeletons: A Pilot Study

OCCUPATIONAL APPLICATIONSThe test proposed in this study, assimilable to a maximal isometric mid-thigh pull, appears to detect the acute assistance provided by the exoskeleton, expressed as the difference in performance with and without donning the device; the test can be perform...

Cultivable diversity and plant growth-promoting traits of free-living bacteria from coffee soils under contrasting fertilization systems

Abstract Brazilian coffee production relies heavily on mineral fertilizers, particularly nitrogen-based inputs. However, the intensive use of these fertilizers is associated with nutrient losses, elevated production costs, and environmental impacts, highlighting the need for more...

Trema micrantha extract for sustainable spider mite management

Abstract Given the increasing demand for sustainable alternatives to synthetic acaricides, this study evaluated the acaricidal activity of aqueous leaf extracts of Trema micrantha Blume (Cannabaceae) against adult females of Tetranychus urticae Koch, 1836 (Acari: Tetranychidae) u...

Surfactantsfor Enhanced Oil Recovery: Progress andInnovations over the Past Decade

Abstract Surfactant-based strategies have emerged as key approaches for enhancing oil recovery (EOR), particularly in mature reservoirs where conventional production methods leave a substantial fraction of oil unrecovered. This review provides a comprehensive and critical assessm...

Effect of carcass electrical stimulation on sheep and goat meat quality: a meta-analysis study

Context The utilization of electrical stimulation (ES) in small ruminant carcasses is less common than in beef processing facilities. Nevertheless, ES shows promise in mitigating cold shortening and improving meat quality traits in small ruminants. Aim This meta-analysis assessed...

Toward Sustainable Water Treatment: Hydraulic Retention Time Effects on Natural and Chemical Coagulants in Continuous-Flow Helically Coiled Tube Flocculators

Access to safe drinking water remains a global challenge, particularly in decentralized and low-resource settings where conventional treatment technologies may be economically or operationally impractical. Combining low-energy hydraulic flocculation systems with biodegradable nat...

Case Studieson Sample Preparation with Diluted Acidfor Elemental Determination

Abstract Green chemistry provides a framework for redesigning laboratory practices to reduce environmental and safety impacts. In elemental analysis, replacing highly concentrated acids during sample preparation represents an important step toward more-sustainable practices. This...

Proteomic profile associated with the m aturation of somatic embryos of Euterpe edulis under polyamine treatments in material derived from a single mother plant

Abstract Euterpe edulis is of ecological and economic relevance and is currently threatened with extinction. Its vulnerability to extinction, combined with the recalcitrant nature of its seeds, justifies the search for alternative reproduction techniques. Somatic embryogenesis is...

Kinectics of calcium diffusion and associated physical changes in papaya fruit

Calcium-based treatments are recognized for their effectiveness in preserving the postharvest quality of papaya; however, the mechanisms and kinetics of calcium diffusion within the fruit pulp remain insufficiently characterized. This study aimed to characterize the calcium diffu...
