Post bleaching procedures often have free radicals trapped in dentin tubule and interprismatic enamel, leading to demineralization and denaturation. Sodium ascorbate is an antioxidant substance known to bind residual fre...

In this study, the heating parameters required for polyamide-11 (P11) coating of the helicopter shaft were investigated. The torsion value created by the force applied to the middle of the helicopter's shaft is measured....

For the molten pool behavior in K-TIG welding, the Level-Set method was used to track the changes in the free surface of the molten pool, and a two-dimensional transient numerical calculation model for stationary welding...

Vegetation optical depth (VOD), as a key parameter of vegetation, plays an important role in the process of vegetation growth and change. The spaceborne Global Navigation Satellite System Reflectometry (GNSS-R) technolog...

IntroductionCD48 is a coactivating receptor within the signaling lymphocytic activation molecule (SLAM) family that is important for the regulation of lymphocyte cytotoxicity and T cell activation. Volkmer et al. previou...

The effect of four commonly consumed beverages as mineral water, coffee, tea and mate tea on the elemental composition of a commercial glass ionomer was studied using Particle Induced X-ray Emission (PIXE) and Rutherford...

Abstract NH₃ and H₂S are major hazardous odorants emitted from intensive livestock operations, presenting distinct challenges for simultaneous removal. This study evaluates a novel layered filtration system utilizing...

ZnO nanorods (ZnO NRs) were grown on ZnO seeded polyethylene tert-phtalate (PET) substrates obtained from recycled soda bottles at low temperatures (90 °C) from Zn2+ precursors in alkaline aqueous solution. The ZnO seed...

Abstract The polar stratosphere in the Northern Hemisphere influences wintertime surface weather across Northern Eurasia, Eastern Canada, the Middle East, and the Eastern United States. This influence is pronounced follo...

In this work we carried out an ultrastructural analysis of the cell interface between oocyte and follicle cells during the oogenesis of the amphibian Ceratophrys cranwelli, which revealed a complex cell-cell interaction....

Tesis de Doctorado En esta tesis se desarrollaron superficies antibacterianas activadas por luz, fabricadas utilizando películas delgadas de zirconia mesoporosa infiltradas con nanopartículas metálicas, específicamen...

Various heterogeneous catalytic reactions, when performed on a flux reactor (i.e. on open systems) under UHV conditions display complex spatiotemporal patterns. Specifically, TPR, Work Function (WF) measurements (both g...

Dos de los elementos de gran interés en procesos relacionados con la contaminación del ambiente son el fósforo y el arsénico. El fósforo no es tóxico en sí, pero es el principal responsable del proceso de eutrofi...

En este trabajo se han estudiado varios de los diferentes procesos que tienen lugar durante el calentamiento y la fusión de superficies de aceros al carbono producidos por irradiación con luz infrarroja coherente. En p...

Se evaluó la reología y el tamaño de partícula de una preparación de surfactante pulmonar conocida como Surfacen® a una concentración de 25 mg/mL a las temperaturas de 23 y 37 °C y se estudió el efecto de la lio...
