Research supported by the Natural Sciences and Engineering Research Council (Canada) and Fonds pour la Formation de Chercheurs et l'Aide a la Recherche (Qu ebec). The algebraic number fields of degree 6 having Galois group S5 and minimum discriminant are determined for signatures (0, 3), (2, 2) and (6, 0). The fields F0, F2, F6 are generated by roots of f0(t) = t 6 + 3t + 2t + 6t + 1, f2(t) = t...

Anaplastic thyroid cancer (ATC) is a highly lethal undifferentiated malignancy without reliable therapies. Retinoic acid (RA) has been employed to promote redifferentiation of thyroid cancers by increasing their I131 uptake and radio-sensitivity, but its effect(s) on ATCs has not yet been ascertained. Likewise, resveratrol induces cancer redifferentiation but, also in this case, its effects on ...

Physical mapping of the 18S ribosomal RNA gene (rDNA) was carried out by fluorescent in situ hybridization (FISH) in the endangered freshwater fish O. belangeri. The specimens were collected from Imphal valley, Manipur, India and metaphase chromosome preparation was made using standard hypotonic treatment, methanol-acetic acid fixation and flame-drying technique followed by Giemsa, silver, CMA3...

Fourier-transform infrared (FTIR) magneto-spectroscopy is a powerful spectroscopic technique used to investigate many important effects in materials, e.g., electron spin resonance, cyclotron and transitions between Landau levels. Despite their enormous potential material science, magneto-spectrometers are still relatively rare custom-made since such systems generally require complex infrastruct...

An investigation is carried out on the systematic analysis of the dynamic behavior of the hybrid squeeze-film damper HSFD mounted a rotor-bearing system with strongly nonlinear oil-film force and nonlinear rub-impact force in the present study. The dynamic orbits of the system are observed using bifurcation diagrams plotted using the dimensionless rotating speed ratio as control parameters. The...

In this review paper different design techniques of multi bit adder are deliberate using linear parameters logic gates. The comparison is carried by several parameter mainly focus on a number of linear threshold gates, a number of CMOS transistor, power dissipation, power delay product (PDP), average power dissipation time delay and size of the full adder circuit. Adder circuits basically imple...

In this study, the karyotypic characteristics of Chondrostoma regium (Heckel, 1843) have been investigated. Fish samples were caught from Karasu River (Euphrates Basin) with fishing net. The live fish transported to laboratory and kept in aerated aquaria before analyses. karyotype analysis was performed kidney gill epithelium cells. It determined that C. had 2n=50 chromosomes. detail, formula a...
