This radionuclide is almost exclusively produced from the decay of its parent 99Mo. 99mTc is themost available and important nuclide used as a diagnostic agent in nuclear medicine. To develop anewly practical 99mTc generator using ( n,y ) 99Mo, an inorganic polymer adsorbent has beendeveloped framed with oxygen-zirconium-chlorine bonds with a high adsorption of Mo, Thepolyzirconium adsorbent wa...

The role of ionic interactions between sodium dodecyl sulfate, SDS, and sapphire surfaces have been studied using specular neutron reflection to determine the structure and composition of adsorbed surfactant layers. Increasing the pH of the solution from 3 to 9 reduces the adsorption by reversing the charge of the alumina. This occurs at lower pH for the R-plane (1102) than the C-plane (0001), ...

It was shown by Loeb (1) that an approximate correspondence exists between the isoelectric points of gelatin or of egg albumin when in solution or adsorbed on the surfaces of microscopic particles. It remained for Abramson (2) to demonstrate a quantitative agreement between his own results for the electric mobility of serum albumin adsorbed on quartz surfaces and measured by the microscopic met...

A set of different donor-π-acceptor compounds having dicyanovinyl as the acceptor and aryl moieties as donors were synthesized by Knoevenagel condensation. The UV-visible absorption and fluorescence spectra were investigated in different solvents. The optical band gab energy (Eg) was linearly correlated with the Hammett resonance effect of the donor to reveal that the higher the value of Hammet...

This paper presents new frequency-domain voice modification techniques that combine the high-quality usually obtained by timedomain techniques such as TD-PSOLA with the flexibility provided by the frequency-domain representation. The technique only works for monophonic sources (single-speaker), and relies on a (possibly online) pitch detection. Based on the pitch, and according to the desired p...

A 3-day-old male baby was diagnosed to have proximal small bowel atresia. At operation type-IIIa jejuno-ileal atresia (JIA) was encountered with a jumbled up sequestered bowel-loop-mass. The jejunum was 10 cm and ileum merely 1 cm. The bowel was sequestered on account of volvulus in-utero. Atresia is derived from Greek words " a " (no) and " tresis " (orifice); and refers to congenital obstruct...

We present a novel mechanism of supersymmetry breaking embeddable in string theory and simultaneously sharing the main advantages of (sequestered) gravity and gauge mediation. It is driven by a Scherk-Schwarz deformation along a compact extra dimension, transverse to a brane stack supporting the supersymmetric extension of the Standard Model. This fixes the magnitude of the gravitino mass, toge...
