Integrating sequencing batch hybrid membrane bioreactor with ozonation for treatment of tissue paper wastewater

Abstract This study assessed the performance of a sequencing batch hybrid membrane bioreactor (SB-HMBR) coupled with ozonation for the treatment of tissue paper wastewater. The SB-HMBR was operated for 90 d with a cycle time of 8.5 h under two aeration intensities, corresponding...

An Evidence-Level Framework for Evaluating Enzyme-Mediated Plastic and Microplastic Transformation

Microbial enzymes have attracted considerable attention as biocatalysts for plastic transformation, yet the experimental evidence supporting reported biodegradation varies substantially in quality and interpretation. Surface-sensitive techniques, molecular-weight analyses, identi...

Discontinuous Peripheral Punctate Echogenic Foci in Thyroid Nodules: A New Sonographic Pattern Suggestive of Papillary Carcinoma

Background: Ultrasound risk stratification systems for thyroid nodules worldwide describe different types of echogenic foci, including punctate echogenic foci (microcalcifications), coarse internal calcifications, and peripheral (rim) calcifications (complete or incomplete), with...

DOPAL links dopamine dysregulation to neurodegeneration: a translational systematic review and meta-analysis

3,4-Dihydroxyphenylacetaldehyde (DOPAL) is the most reactive dopamine (DA)-derived aldehyde and has been implicated in selective dopaminergic neurodegeneration in α-synucleinopathies, including Parkinson’s disease (PD) and multiple system atrophy (MSA). Here, we present the first...

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...

Learning Domains for Undergraduate Dental Behaviour Support: The BeSiDe Curriculum Learning Outcomes

OBJECTIVES: Dental Behaviour Support (DBS) refers to informal and formal strategies and interventions that support patients' acceptance and experience of oral healthcare. DBS plays a crucial role, particularly for vulnerable groups, yet training across dental curricula remains in...

Towards Hybrid Blockchain Integrated With IoT Applied for Supply Chain Tracking

ABSTRACT Background Preserving the quality and safety of perishable products requires continuous monitoring and reliable traceability. Although the Internet of Things (IoT) enables real‐time data collection, multi‐organizational supply chains lack a common mechanism for assigning...

Beyond Cell Expansion: Microcarriers as Functional and Edible Platforms for Cultivated Meat Production

Abstract Cultivated meat has emerged as a promising strategy to mitigate the environmental impacts of conventional livestock production; however, its industrial scalability remains limited by the need to scale up anchorage-dependent cell cultures efficiently. Microcarriers have b...

The Human Dimension of Araucaria Forest: Resource Uses, Landscape Management, and Ethnozoology

Abstract Local knowledge is a useful tool for understanding historical ecological processes and landscape management. We evaluated the ecological history of Araucaria Forest, including the use of its resources ( Araucaria angustifolia (Bertol.) Kuntze [Araucaria seeds] and Feijoa...

Objective Evidence for Mind–body Interventions: Selective Modulation of Meridian-wise Bioelectrical Conductance by Yogic Practices

Abstract Introduction: Traditional Chinese Medicine (TCM) describes meridians as channels through which vital energy (Qi) flows, with disturbances in this flow associated with disease. Contemporary research has demonstrated that classical meridian points possess distinctive elect...

Predicting the combustion behavior of straight soybean oil/diesel blends: an integrated numerical and experimental assessment

Abstract This study presents a numerical characterization of the combustion process of straight soybean oil (SSO)/diesel blends using the AVL BOOST™ engine model. Validated against experimental data from a single-cylinder Yanmar YT22E engine, the work investigates four blend comp...

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,...

Fiberoptic endoscopic evaluation of swallowing in neurogenic oropharyngeal dysphagia in adults: Part 2 of a scoping review

PURPOSE: The main objective of this scoping review was to describe the qualitative and quantitative parameters of fiberoptic endoscopic evaluation of swallowing (FEES) protocols, including their operational definitions and scales used in adults with neurogenic oropharyngeal dysph...

Direct ink writing of geopolymer adsorbents: A review

Geopolymers (GPs) are amorphous aluminosilicate binders valued as low-cost adsorbents for their cation-exchange capacity, tunable porosity, and chemical stability. Direct ink writing (DIW) has recently emerged as a processing route to shape these materials into structured lattice...

Development of Periodontal Organoid-like Constructs Using Human Periodontal Ligament and Gingival Epithelial Cells: Comparison of Two Assembly Strategies

Periodontal organoid research remains underdeveloped, largely due to the lack of standardized fabrication protocols and multicellular constructs capable of reproducing epithelial–mesenchymal interactions relevant to periodontal biology. In particular, it remains unclear whether d...

Violence, Stigma, and Moral Injury in Nursing During the COVID‐19 Pandemic: A Qualitative Analysis From 18 Countries in Latin America and the Caribbean

Workplace violence against nurses and midwives intensified during the COVID-19 pandemic, exposing and amplifying longstanding structural marginalization in health systems across Latin America. This study analyzes how different forms of violence were experienced and described by n...

Pathological, microbiological, and molecular characterization of uterine samples in culled sows from farms with a history of reproductive failure in Brazil

Reproductive failure in swine herds is an important cause of production losses and increased sow culling. While many diagnostic efforts focus on abortion-derived samples, the evaluation of reproductive tracts from culled sows may provide additional insights. This study aimed to c...
