In-situ assessment of machinability and chip formation through the dynamic cont...

This work introduces a novel methodology for high-precision online monitoring of the tool-workpiece interaction in milling operations. The proposed Dynamic Contact Electrical Resistance Measurement (DyCERM) method for machining monitoring, combines user-friendly software with cost-effective hardware to measure the voltage drop across the dynamic tool-workpiece contact interface. Theoretically, DyCERM can be use...

Knowledge, Self-Care and Fragility Fracture Risk: An Exploratory Study Informin...

Introduction Fragility fractures (FF) are a growing public health problem, with 70,700 cases recorded in Portugal in 2019.¹ These fractures are associated with a one-year mortality rate of 25%² and a major economic impact. The management of FF risk comprises multiple interacting components, in which knowledge and the ability to perform self-care activities are key elements.3 Objective To explore the association...

Reactive Infectious Mucocutaneous Eruption: A Rising Enigma

Reactive infectious mucocutaneous eruption is a rare condition that predominantly occurs in pediatric patients following a respiratory infection, most commonly caused by Mycoplasma pneumoniae. It is characterized by prominent mucositis, usually with minimal or absent skin involvement. We present the case of a nine-year-old male admitted with severe oral mucositis and a penile lesion compromising bladder emptyin...

Strawberry Tree Fruit Residue as Carbon Source Towards Sustainable Fuel Biodesu...

ABSTRACT: Biodesulfurization (BDS) is a clean technology that uses microorganisms to efficiently remove sulfur from recalcitrant organosulfur compounds present in fuels (fossil fuels or new-generation fuels resulting from pyrolysis and hydrothermal liquefaction). One of the limitations of this technology is the low desulfurization rates. These result in the need for greater amounts of biocatalyst and lead to in...

New Insights on Gordonia alkanivorans Strain 1B Surface-Active Biomolecules: Go...

ABSTRACT: Biosurfactants/bioemulsifiers (BSs/BEs) can be defined as surface-active biomolecules produced by microorganisms with a broad range of applications. In recent years, due to their unique properties like biodegradability, specificity, low toxicity, and relative ease of preparation, these biomolecules have attracted wide interest as an eco-friendly alternative for several industrial sectors, escalating g...

Rapid Four-Compartment Models in Athletes Using Alternative Solutions for Body ...

The criterion four-compartment (4C) model combines dual-energy x-ray absorptiometry (DXA), deuterium dilution, and air displacement plethysmography (ADP), but its complexity limits practicality. This study aimed to externally validate a DXA-derived body volume (BV) equation (DXA-BVSilva) and assess the accuracy of a rapid 4C model replacing deuterium dilution total body water (TBW) with bioelectrical impedance ...

Cochrane Corner – Fall prevention interventions for older adults residents in c...

As quedas na pessoa idosa são uma das principais causas de morbilidade e mortalidade prematura, constituindo um problema de saúde pública de grande relevância. Esta revisão sistemática Cochrane, atualiza revisões anteriores, avaliando 104 ensaios clínicos aleatorizados e controlados, envolvendo 68.964 pessoas com ≥65 anos, residentes em estruturas residenciais para idosos. A meta-análise compara a efetividade d...

Air pollution dynamics: the role of meteorological factors in PM10 concentratio...

Air pollution is a major health problem in urban areas, influenced by traffic and atmospheric conditions. This study investigates the relationship between meteorological factors—wind direction, wind speed, boundary layer height, and atmospheric stability conditions —street trees, and PM10 concentration in three urban canyons: Avenida da Liberdade and Estrada de Benfica in Lisbon, and Marginal Tietê in São Paulo...
