The aim of this study was to determine degree conversion (DC) solid and flowable bulk-fill composites immediately after 24 hours investigate the variations DC at surface depths up 4 mm.Eight (Tetric EvoCeram Bulk Fill [shades IVA IVB], Quixfil, X-tra fil, Venus Fill, Base, SDR, Filtek Fill) were investigated, two conventional (GrandioSO, X-Flow) used as controls. samples (n = 5) cured for 20 seconds with irradiance 1090 mW/cm(2). Raman spectroscopic measurements made curing on sample...
The variable configuration of Raman spectroscopic platforms is one the major obstacles in establishing spectroscopy as a valuable physicochemical method within real-world scenarios such clinical diagnostics. For real world applications like diagnostic classification, models should ideally be usable to predict data from different setups. Whether it done by training rugged model with many setups or primary-replica strategy where are developed on 'primary' setup and test generated 'replicate'...
The major obstacle to successful chemotherapy of cancer patients is drug resistance. Previously we explored the molecular mechanisms curcumin cross-resistance in carboplatin resistant human laryngeal carcinoma 7T cells. Following treatment found a reduction accumulation, and reduced induction reactive oxygen species (ROS) their downstream effects, compared parental HEp-2 In order shed more light on involved resistance cells, present study applied Fourier transform infrared (FTIR)...
Microporous and macro-mesoporous silicon templates for surface-enhanced Raman scattering (SERS) substrates were produced by anodization of low doped p-type wafers. By immersion plating in AgNO3, the covered with silver metallic film consisting different nanostructures. Scanning electron microscopy (SEM) micrographs these SERS showed diverse morphology significant difference an average size distribution nanoparticles. Ultraviolet-visible-near-infrared (UV-Vis-NIR) reflection spectroscopy...
The aim of this study was to evaluate water sorption and solubility two series experimental composites containing amorphous calcium phosphate (ACP) or bioactive glass (BG). Water were measured for up 287 days. surface precipitation phosphates evaluated by scanning electron microscopy. ACP-series showed higher (223-568 µg/mm3) than the BG-series (40-232 µg/mm3). In contrast, had generally lower (37-106 (1-506 constant specimen mass attained after 14 days immersion, while decrease due...
This study assessed the influence of rapid 3 s light curing on new generation bulk-fill resin composites under simulated aging challenge and depths up to 4 mm. Four materials were tested: two designed for (Tetric PowerFill—PFILL; Tetric PowerFlow—PFLW) regular (Filtek One Bulk Fill Restorative—FIL; SDR Plus Flowable—SDR). Three-point bending (n = 10) was used measure flexural strength (FS) modulus (FM). In group, 2 mm thick specimens stacked obtain thickness, while mm-thick ISO group....

Surface-enhanced Raman scattering (SERS) with near-infrared (NIR) excitation offers a safe way for the detection and study of fragile biomolecules. In this work, we present possibility using silver-coated porous silicon photonic crystals as SERS substrates (1064 nm) excitation. Due to deep penetration NIR light inside silicon, fabrication was necessary quench band gap photoluminescence crystal, which acts mechanical support layer. Optimal parameters immersion plating process that gave...
Gender determination of the human remains can be very challenging, especially in case incomplete ones. Herein, we report a proof-of-concept experiment where possibility gender recognition using Raman spectroscopy teeth is investigated. spectra were recorded from male and female molars premolars on two distinct sites, tooth apex anatomical neck. Recorded sorted into suitable datasets initially analyzed with principal component analysis, which showed distinction between teeth. Then, reduced...
Recently, it was found that when confronted with major vessel occlusion and vascular failure, stable gastric pentadecapeptide BPC 157 therapy might rapidly functionally improve minor vessels to take over the function of disabled vessels, reorganize blood flow, compensate failed function. We focused on effect obtained by giving 10 ng/kg ip rats 5 min before sacrifice rat thoracic aorta, which we assessed Fourier transform infrared spectroscopy (FTIR) 90 thereafter. applied a principal...
Light emitting porous silicon samples with different porosities, i.e. crystalline sizes, were produced from the low level doped p‐type wafers by anodization process. The effects of strong phonon confinement, redshift and broadening, found on O(Γ) mode Raman spectra recorded at non‐resonant excitation condition using a near infrared 1064 nm laser wavelength. Similarly, blueshift photoluminescence peak was observed reducing sizes. Vibrational optical findings analysed within existing models...

Abstract In this work, it is shown that student access time series generated from Moodle log files contain information sufficient for successful prediction of final results in blended learning courses. It also if transformed into frequency domain, using discrete Fourier transforms (DFT), the contained will be preserved. Hence, resulting periodogram and its DFT coefficients can used generating performance models with algorithms commonly purposes. The amount data extracted files, especially...
We studied the generation of an ordered Ge quantum dot array in amorphous silica matrix by ion beam irradiation.
