From Seaweed to Corrosion Inhibitor: A Multi-MethodValidation of λ-Carrageenan as a Non-Toxic Inhibitorunder Acidic Hydrodynamic Conditions

Abstract Corrosive processes are responsible for direct and indirect costs in industrial systems, which can be mitigated by corrosion inhibitors. The awareness of environmental risks has motivated sustainable approaches, such as naturally derived biopolymers, due to low toxicity...

Population Dynamics and Extractive Potential of the Mangrove Crab, Ucides cordatus (Linnaeus, 1763), in a Human-Impacted Mangrove of Northeastern Brazil

Ucides cordatus, a key species in Brazilian mangroves, supports both ecological processes and traditional extractive practices. Some mangrove areas in Northeastern Brazil are increasingly exposed to anthropogenic stressors. We evaluated the population density, size structure, ext...

A lean-based method for patient journey improvement: enhancing value and performance in healthcare delivery

Purpose This research introduces a lean-based method, from the customer’s perspective, aimed at continuously improving the sequence of value and non-value stages throughout the purchase journey, named the ideal customer journey method (ICJM). Design/methodology/approach The ICJM...

Forensic facial approximation methodologies applied to the Brazilian population: a scoping review

Impact of GLP-1 and GLP-1/GIP receptor agonists before, during, and after pregnancy: a narrative review

Glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic peptide (GIP) receptor agonists (GLP-1RA and GIP-RA) are a class of medications that mimic the endogenous effects of GLP-1 and have gained increasing attention due to their substantial clinical potential. Origin...

IntegratedEffects of Key Process Variables on CH4–CO2 Exchange in Gas Hydrates: Insightsinto Driving Forces and Mechanisms

Abstract Methane (CH4) hydrates are considered a promising low-carbon energy resource due to their vast global reserves; however, their exploitation poses environmental risks, particularly CH4 leakage. The CH4–CO2 exchange process, also referred to as CH4/CO2 replacement, has bee...

From Fragmented DMD Management Toward Digitally Enabled Circularity: A Conceptual Operations Framework for Durable Medical Devices

Durable medical devices (DMD) are essential healthcare assets, yet their management in public hospitals is constrained by fragmentation, limited traceability, reactive maintenance, and weak lifecycle integration. This study proposes a framework for digitally enabled, sustainable,...

For-me-ness: a critical assessment of the phenomenal mineness thesis

This paper examines the claim that the phenomenal "for-me-ness" is the core feature of every conscious experience. Any conscious episode is intrinsically given as mine, and this mineness, while non-reflective and non-cognitive, belongs to the personal and phenomenal level. The co...
