چکیده

This communication describes a new method for producing stable, high concentrations of Sc21 in optically clear CaF2 crystals. We have achieved Sc21 concentrations as high as 3 3 1018 cm23 without degradation of optical quality. We have converted as much as 5% of the scandium dopant to the divalent state. The concentration of divalent scandium is stable during room temperature storage for periods of at least one year.

A dual detector b-ray imaging probe with c-ray background suppression for use in intra-operative detection of radiolabeled tumors

The basic concepts for a dual detector b` imaging probe incorporating a method of c-ray background suppression were evaluated. The test devices consisted of a 1.2 cm2 b` imaging CaF 2 (Eu) scintillator disk optically coupled to a 1.7 mm thick, area-matched transparent diffuser disk, which in turn was coupled to sets of 2]2 or 4]4 mm2 by 10 mm long BGO, GSO or LSO scintillators, which acted as b...

“Study of stable gallium oxide heavey metal Ga2O3-Bi2O3-PbO system glasses proposed as a base for optically noble glazes and enamels”

Ultra optical glasses are proposed for attaining noble glazes of high reflection and shine. In addition, these glasses can be used as semi-mirrors and optical instruments. In this reseach attempts were devoted mainly to introduce a glass system with the highest possible refractive index in which the highest reflection is desirable. Thus different amounts of heavy metal oxides modifiers, such as...

Expression of Recombinant Factor IX Using the Transient Gene Expression Technique

Background: Pilot and large-scale production of recombinant proteins requires the presence of stable clones capable of producing large quantities of recombinant proteins. Not only the process of selecting stable clones is time consuming, but also the continuous culturing of clones in large-scale production may cause loss of incoming plasmid and recombinant genes. Thus, considering the advanceme...

The isolation of halophilic urease-producing bacteria and the study of their nano-crystal production

Urease-producing bacteria can precipitate calcite nano-crystals by producing urease in the presence of urea and calcium. Calcite precipitation resulting from microbial activity is a process which causes cementation of soil particles in nature. The purpose of this study was to isolate urease-producing halophilic bacteria in order to precipitate calcite in saline soil. Natural samples, including ...

Controlling the Occurrence of Rogue Waves in an Optically Injected Semiconductor Laser via Changing The Injection Strength

The rouge waves in an optically injected semiconductor lasers are receiving a lot of interest. In this work, the generating and controlling of the rogue waves in semiconductor lasers have been investigated. For this purpose, the laser’s rate equations are solved numerically in a specified time interval, then the field amplitude and the intensity versus time are calculated and analyzed. To solve...
