There is substantial evidence that genetic variation, at both the level of the individual and population, has a significant effect on behaviour, fitness and response to toxicants. Using DNA microsatellites, we examined the genetic variation in samples of several commonly used laboratory strains of zebrafish, Danio rerio, a model species in toxicological(More)
The potential organic non-linear optical single crystal of L-lysine acetate has been grown by slow evaporation solution growth technique (SEST) at room temperature. It crystallizes in the monoclinic system with space group of P2(1). The crystalline perfection of the grown single crystal has been examined by high resolution X-ray diffraction analysis(More)
Nonlinear optical single crystals are getting attention because of its enormous applications in the area of fiber optic communication and optical signal processing. In this article, we are reporting the single crystal growth of l-lysine monohydrochloride by slow evaporation solution growth technique, by using double distilled water as the solvent. We found(More)
Single crystal of semi organic nonlinear optical material of bis thiourea cadmium acetate were grown by slow evaporation technique from its aqueous solution. The cell parameters are verified by single crystal X-ray Diffraction. Fourier transform infrared spectrum (FT-IR) is used to confirm the presence of various functional groups in the grown crystal. The(More)
Single crystals of acetoacetanilide have been successfully grown by slow evaporation solution growth method at room temperature. The grown crystal belongs to orthorhombic crystal system having the lattice dimensions of a=8.686Å, b=11.104Å, c=19.232Å. Its crystalline perfection was examined by home-made high resolution X-ray diffractometer (HRXRD), and found(More)
Glycine glutaric acid, a new organic compound has been synthesized and good quality single crystals were grown by slow evaporation technique. The structure of the grown crystal was elucidated by using single crystal XRD. The presence of the functional groups was confirmed by using FT-IR spectroscopy. The optical transparency was studied by using UV-vis(More)
In this paper, different methods to detect micro-cracks were compared. Their capability of detecting fatigue induced micro-cracks in metal was evaluated, as well as the possibility to apply them to detect micro-cracks induced by bending in steel plates. All methods found in literature use one of four different physical phenomena. Out of these methods, the(More)
Single crystals of pure and l-Proline (LP) C5H9NO2 doped ammonium dihydrogen phosphate (ADP) (NH4) H2PO4 were grown by slow evaporation solution technique (SEST) at ambient conditions. Powder X-ray diffraction (PXRD) analysis was carried out to confirm the crystal structure and no additional phase was observed due to doping except a systematic variation in(More)
Good quality single crystals of potassium dihydrogen orthophosphate (KDP) were grown with different doping concentration of Glycine by conventional solution technique in aqueous solution. X-ray diffraction study has been carried out in order to see the effect of dopant on the structural parameters of KDP. There is no additional phase was observed which was(More)
