We have reported the study of methanol/AOT/n-heptane reverse micellar aggregates using Fourier Transform Infrared (FTIR) spectroscopy. We have divided our whole work into two parts. In the first part we have studied the structural properties of Aerosol OT (AOT) reverse micelles by monitoring the changes in the symmetrical sulfonate stretching region (1000-1100 cm(-1)), asymmetrical sulfonate st...

The resonance Raman spectra of (IAuI)~-anions in the organic superconductor Y?-(BEDTTTF)2IAUI as well as in the electrolyte salt n-Bu4AuI2 are investigated. In contrast to /?-(BEDT-TTF)2I3 in the crystals of /?-(BEDT-TTF)2IAuI at low temperature only one Raman line at 120 cm" 1 corresponding to the symmetrical stretching mode of the (IAuI)"-anion is observed. No distinct change in the Raman spe...

Disodium hydrogen orthophosphate is a water soluble white powder widely used as pH regulator and saline laxative. The sodium nitrate is a highly water soluble white solid, used in high blood pressure, dentinal hypersensitivity, and production of fertilizers. The present study was aimed to investigate the impact of biofield treatment on spectral properties of disodium hydrogen orthophosphate and...

A rhyolite glass containing about 300 ppm by weight of H'O was heated in a microscope heating stage to 1300 oC, and true infrared absorbance spectra were obtained in situ at various temperatures using an FTIR spectrometer, together with the focusing optics of an IR microscope. Virtually all HrO dissolved as OH at all temperatures. However, large changes both in band shape and integral extinctio...

The modern engineering structures require the advanced engineering materials to resist the high temperatures and to provide high stiffness. In particular the functionally graded porous materials (FGPMs) introduced are expected to have these desired properties, consequently eliminating local stress concentration and de-lamination. In the present paper, a new shear strains shape function is chose...

The Wingate Anaerobic Test (WAnT) has been used in many studies to determine anaerobic performance. However, there has been poor reporting of warm-up protocols and limited consistency between warm-up methods that have been used. With the WAnT being such a commonly-used test, consistency in warm-up methods is essential in order to compare results across studies. Therefore, this study was designe...

This study aimed to compare the effect of different static stretching durations followed by dynamic stretching on repeated sprint ability (RSA) and change of direction (COD). Twenty-five participants performed the RSA and COD tests in a randomized order. After a 5 min aerobic warm up, participants performed one of the three static stretching protocols of 30 s, 60 s or 90 s total duration (3 str...

Stretching is often included as part of a warm-up procedure for basketball activity. However, the efficacy of stretching with respect to sport performance has come into question. We determined the effects of 4 different warm-up protocols followed by 20 minutes of basketball activity on flexibility and vertical jump height. Subjects participated in 6 weeks (2 times per week) of warm-up and baske...
