Comparison of a local made temporary cement (P-cem), with an imported brand (Temp Bond) using ISO 3107 criteria Dr. Fallahi, M.R.* - Dr. Bayan Zadeh, S.M.** - Dr. Malkomian, L.*** *Dentist. **Assistant Professor of Prosthodontics Dept., Faculty of Dentistry, Tehran University / Medical Sciences. ***Statistician. Abstract Background & Aim: The local made eugenol-free temporary cement (P-cem) has...
According to embodied theories, the symbols used by language are meaningful because they are grounded in perception, action, and emotion. In contrast, according to abstract symbol theories, meaning arises from the syntactic combination of abstract, amodal symbols. If language is grounded in internal bodily states, then one would predict that emotion affects language. Consistent with this, advoc...
The coordinate frames used by theoreticians to describe wave propagation do not include frames in common use by geophysical prospectors to describe observations. Whereas the theoretician generally considers a single source (or shot) location at a time, the experimentalist deals simultaneously with waves which have been generated separately by many shots. Our task in this section is to put the w...
in this research, the mechanical properties of seven types of nanofilm with differing amounts of silver and silver-clay particles were studied. the elasticity of modulus, tensile strength, toughness, elongation at break, tear strength and color of nanofilms were compared with those of ordinary ldpe film. results showed that the inclusion of nano particles increased the modulus of elasticity, te...
1 Abstract—Historians of electrical technology deal routinely with inventions, inventors, theoreticians, large-scale sociotechnological systems, and corporate and institutional history. Yet one category of major contributor to the development of the discipline is rarely considered in detail: the engineering educator. This paper presents the contribution of one of the outstanding teachers of ele...
Flexible Capacitive Pressure Sensor with Microstructure Array for Human Pulse Sensing 1. Abstract In this project, we designed a capacitive pressure sensor for blood pressure and human pulse detection using flexible copper film and PDMS [dielectric] microstructure sandwich structure. We observed a linear relation between force and change in capacitance and detected a human pulse [pressure]. Thi...
Abstract: In the actual study, two digital detectors were investigated : an amorphous silicon flat panel and a TDI multilinear detector. The contrast and IQI sensitivity was selected to compare flat panel and film radiography. The influence of X-ray conditions was assessed in the case of flat panel. Spatial resolution of both digital detectors was assessed by adapting the geometrical magnificat...
Haiqing Xianyu Kuan-Ming Chen Shin-Tson Wu Abstract — An electrically controllable blueshift of the reflection band is observed in a cholesteric liquid crystal with either positive or negative dielectric anisotropy. The change in optical properties is a result of a two-dimensional periodic undulation of the cholesteric texture, known as Helfrich deformation. This blueshift mechanism was used to...
Suehye Park (SID Student Member) Abstract — Amorphous Edward Namkyu Cho Ilgu Yun In–Ga–Zn–O thin-film transistors (TFTs) have attracted increasing attention due to their electrical performance and their potential for use in transparent and flexible devices. Because TFTs are exposed to illumination through red, green, and blue color filters, wavelength-varied light illumination tests are require...
