Response of Human Gingival Fibroblasts and Porphyromonas gingivalis to UVC-Activated Titanium Surfaces

open access: yesJournal of Functional Biomaterials, 2023
Ultraviolet (UV) photofunctionalization has been demonstrated to synergistically improve the osteoblast response and reduce biofilm formation on titanium (Ti) surfaces.

Strength anisotropy at soil-structure interfaces with snake skin inspired structural surfaces [PDF]

open access: yesE3S Web of Conferences, 2019
Typical soil-structure interfaces exhibit a response that is independent of loading direction due to the symmetry of the surfaces' profile. This study presents results from an experimental investigation on the response of sand specimens sheared against ...

Spin-isospin surface responses

open access: yesPhysics Letters B, 1987
Abstract The excitation of spin-isospin modes at the surface of a nucleus is investigated in an RPA framework, utilizing a harmonic oscillator basis. The effect of the mixing between the spin-longitudinal and spin-transverse couplings is found to play an important role in explaining the absence of contrast in the ratio between the longitudinal and ...

The influence of different technological co-adjuvants on the quality and yield of virgin olive oil using response surfaces methodology

open access: yesGrasas y Aceites, 2008
Response surface methodology was employed to evaluate the effects of two technological co-adjuvants in virgin olive oil extraction from the Hojiblanca olive variety with a low ripening index: the addition of talc during the malaxation of the olive paste ...

Local and Systemic In Vivo Responses to Osseointegrative Titanium Nanotube Surfaces

open access: yesNanomaterials, 2021
Orthopedic implants requiring osseointegration are often surface modified; however, implants may shed these coatings and generate wear debris leading to complications. Titanium nanotubes (TiNT), a new surface treatment, may promote osseointegration.

Parametric analysis of the ionic concentrations effects in the behavior of the sinoatrial node

open access: yesRevista Facultad de Ingeniería Universidad de Antioquia, 2013
A sensibility study on the effect of ionic concentrations in the behavior of the sinoatrial node was carried out. The study was based on the model proposed by H. Zhang, A. V. Holden and M.R. Boyett.

Green/sustainable treatment of washing machine greywater for reuse in the built environment

open access: yesCleaner Engineering and Technology, 2022
Given the growing demand for water in the world, approaches and/or actions are needed to reduce consumption and increase demand. In the latter case, water reuse is a viable alternative to increase the demand for non-potable water in homes.

Otimização da resistência mecânica de corpos cerâmicos em função de matérias-primas e restrições de propriedades tecnológicas Optimization of mechanical strength of ceramic bodies as a function of raw materials and restrictions on technological properties

open access: yesCerâmica, 2005
No desenvolvimento e fabricação de revestimentos cerâmicos, propriedades tecnológicas são determinadas basicamente pela combinação de matérias-primas e condições de processamento.

Effect of Wear-Corrosion of Reduced Graphene Oxide Functionalized with Hyaluronic Acid on Inflammatory and Proteomic Response of J774A.1 Macrophages

open access: yesMetals, 2023
The presence of a worn surface in the implanted material, as in the case of a replacement of a damaged osteoarticular joint, is the normal condition after implantation.

The initial inflammatory response to bioactive implants is characterized by NETosis. [PDF]

open access: yesPLoS ONE, 2015
Implants trigger an inflammatory response, which is important for osseointegration. Here we studied neutrophil extracellular trap (NET) release of human neutrophils in response to sandblasted large-grit acid etched (SLA) implants using fluorescent ...
