Natural Nanohydroxyapatite Synthesis via Ultrasonication from Donax Trunculus Bivalve Sea Shells and Production of its Electrospun Nanobiocomposite
(POLISH ACAD SCIENCES INST PHYSICS, 2019)
In the present study, hydroxyapatite (HA) and tricalcium phosphate (TCP) bioceramics were prepared via a practical, ultrasonic conversion method from Donax trunculus seashells. These seashells are one of the most common ...
Earthquake damage assessment of 1-story precast industrial buildings using damage probability matrices
(Springer Netherlands, 2019)
In this study, risk assessment of 1-story precast building is conducted in probabilistic manner by using damage probability matrices (DPMs). Peak ground velocity (PGV) is used as reference ground motion parameter to associate ...
The Small Index Property For Free Nilpotent Groups
(TAYLOR & FRANCIS INC, 2015)
Let F be a relatively free algebra of infinite rank x.We say that F has the small index property if any subgroup of Gamma = Aut(F) of index at most x contains the pointwise stabilizer Gamma(U) of a subset U of F of cardinality ...
Realization of Dielectric Sheets for Gain Improvement of Ultra-Wideband Horn Antennas Using 3D Printer Technology
(APPLIED COMPUTATIONAL ELECTROMAGNETICS SOC, 2019)
In this work, 3D printing technology had been used to prototyped 10 dielectric sheets with relative dielectric constant of 2.5 for gain improvement of a TEM horn antenna. By loading the 3D printed dielectric sheets to the ...
Partial-wave analysis of J /? ?k+K-?0
(American Physical Society, 2019)
A partial-wave analysis of the decay J/??K+K-?0 has been made using (223.7±1.4)×106 J/? events collected with the BESIII detector in 2009. The analysis, which is performed within the isobar-model approach, reveals contributions ...
Variation of the raman frequency of a soft mode with the pressure (20 oc) for the phase transitions in NH4F
(2016)
The Raman frequency of a soft mode (238 cm-1) is analyzed as a function of pressure at 20 oC for NH4F using the experimental data from the literature. This analysis is performed for the pressure dependence of the Raman ...
Bioactivity of Hydroxyapatite Produced from Sea Snail Turritella Terebra
(POLISH ACAD SCIENCES INST PHYSICS, 2019)
In this study, hydroxyapatite was produced via mechanochemical method using the sea snail Turritella terebra as a calcium source at 1200 degrees C followed by sintering. FT-IR, SEM/EDX, BET, XRD, ICP-OES analyses were ...
A Roadside Study of Observable Driver Distractions
(Taylor&Francis, 2015)
Objective: This study investigated the prevalence of observable distractions while driving and the effect of drivers' characteristics and time-related variables on their prevalence. Methods: Using roadside observation, 2 ...
A Neural Marker of the Start-Gun in Interval Timing: Onset N1P2
(AMER PSYCHOLOGICAL ASSOC, 2019)
Although the neural markers of interval timing have been widely studied, the events that determine the onset and offset of an interval have only recently started to gain attention. In the present study, I compare the ...
Bioceramic production from giant purple barnacle (Megabalanus tintinnabulum)
(Trans Tech Publications Ltd, 2015)
In this study the structural and chemical properties of barnacle shell based bioceramic materials (i.e. hydroxyapatite, whitlockite, monetite and other phases) were produced by using mechano-chemical (hot-plate) conversion ...
