Neonatal Ketamine Alters High-Frequency Oscillations and Synaptic Plasticity in the Subiculum But Does not Affect Sleep Macrostructure in Adolescent Rats

open access: yesFrontiers in Systems Neuroscience, 2020
Exposure to sedative/hypnotic and anesthetic drugs, such as ketamine, during the critical period of synaptogenesis, causes profound neurotoxicity in the developing rodent and primate brains and is associated with poor cognitive outcomes later in life ...

A Smile From the Past: Exploring a Fixed Bone Dental Bridge From Eighteenth/Nineteenth Century Porto (Portugal)

open access: yesInternational Journal of Osteoarchaeology, EarlyView.
ABSTRACT This paper presents the first documented case of a fixed bone dental bridge in Portugal. This item was recovered alongside the remains of a young adult individual of indeterminate sex from the 19th century burial site of the 3rd Order of Our Lady of Carmo in Porto, Portugal.

Current Trends and Future Prospects of Integrating Electrospinning With 3D Printing Techniques for Mimicking Bone Extracellular Matrix Scaffolds

open access: yesJournal of Polymer Science, Volume 63, Issue 6, Page 1481-1504, 15 March 2025.
ABSTRACT This article presents a review of the recent findings on the combination of electrospun nanofibers and three‐dimensional (3D)‐printed structures for extracellular matrix (ECM) scaffolds for bone tissue engineering. We explore the synergy between electrospinning (ES), which produces highly porous, fibrous structures from materials like collagen

The influence of welding parameters on macrostructure and mechanical properties of Sc-modified AA2519-T62 FSW joints

open access: yesManufacturing Review, 2020
In this investigation, a 5 mm thick extrusion of AA2519-T62 alloy has been welded using friction stir welding method. The various sets of process parameters have been involved within the range of 400–1200 rpm tool rotation speed and 100–800 mm/min ...

Interfacial Nano‐Pitting and In Situ Sulfate‐Directed Growth of Na2.85V2(PO4)2.85(SO4)0.15 Nanodots on MWCNT for Ultrafast Sodium‐Ion Storage

open access: yesSmall, EarlyView.
Ultracentrifugation‐assisted phosphate–sulfate treatment induces self‐limiting nano‐pitting on carbon nanotube surfaces, creating confined sites for in situ growth of Na2.85V2(PO4)2.85(SO4)0.15 nanodots. This embedded nanodot–carbon interface ensures strong electronic coupling and short ion pathways, enabling capacitor‐like sodium storage with ...

Determination of Elements and Carbon Content of Stainless Steel Welded Pipeline

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2016
Find out defects or problems of welds are not so simple from time to time. Specially, if weld has been made in rough environmental conditions like high temperature, dusty wind and humidity.

The new blueprint : Moving towards university knowledge city [PDF]

open access: yes, 2010
All knowledge is a form of tradition, whether ingrained in its structure, content, or the value that people attribute to it. Civilized societies have great traditions of knowledge, and the post modern era which discovered print and digitalization gives ...

Large Scale Earth's Bow Shock with Northern IMF as simulated by PIC code in parallel with MHD model

open access: yes, 2016
In this paper, we propose a 3D kinetic model (Particle-in-Cell PIC ) for the description of the large scale Earth's bow shock. The proposed version is stable and does not require huge or extensive computer resources.

Insights Into Paint‐Bake Toughening of Resistance Spot Welds of a 2.0 GPa Warm‐Stamped Medium‐Mn Steel

open access: yessteel research international, EarlyView.
Paint baking of resistance spot welded joints of 2.0 GPa warm‐stamped medium‐Mn steel activates low‐temperature tempering, forming fine cementite in the fusion zone and enhancing toughness. Crack propagation resistance increases, shifting the failure mode from partial interfacial to complete pullout, with peak load and energy absorption rising ...
