Background: Dual-energy X-ray Absorptiometry (DXA) is considered the gold standard for non-invasive measurement of bone mass. T-scores and Z-scores are used to present the results of bone mass. The present study was designed to evaluate the discordance between T-scores and Z-scores calculated at a same level and its relation with age, gender and body mass index (BMI) in a representative sampl...

In this paper, by capitalizing on z-scan technique and using cw He–Ne laser at 632.8 nm, we investigated the impact of added MgO nanoparticles nonlinear optical properties 6CHBT liquid crystal which was doped with Sudan black B dye. The applied cell had homogeneous alignment. were to 0.3 wt.% dye three concentrations 0.1, 0.6 wt.%. It found that did not significantly change refractive index com...

BACKGROUND & AIMS Malnutrition is a serious concern for children with cancer and nutrition screening may offer a simple alternative to nutrition assessment for identifying children with cancer who are at risk of malnutrition. The present paper aimed to evaluate the nutrition screening tool for childhood cancer (SCAN). METHODS SCAN was developed after an extensive review of currently available...

In this research, Ag nanoparticles were prepared by using g-radiation at concentration of 5.18×10-3 M and irradiated at different doses. A green laser was employed as excited source for measuring nonlinear refractive index and absorption coefficient. The measurements were done by z-scan method for both, closed and open aperture at temperature room. We deduced that with growth of size of Ag nano...

We propose a new design for testability technique, Parallel Serial Full Scan (PSFS), for reducing the test application time for full scan embedded cores. Test application time reduction is achieved by dividing the scan chain into multiple partitions and shifting in the same vector to each scan chain through a single scan in input. The experimental results for the ISCAS89 circuits showed that PS...

We present a detailed investigation on the intensity dependent third-order nonlinear optical (NLO) properties of RF-sputtered WSe2 thin film using ultra short pulses. The employed single-beam Z-scan technique near-infrared (NIR) pulses centered at 1030 nm for ascertaining NLO response. results reveal reverse saturable absorption (RSA) signature, which is primarily due to contribution from two-p...
