Transmission electron microscopy

maintaining all parameter values “in range” and response goal was set to “maximize” mode. The optimum parameter which was predicted by the RSM model was then validated experimentally in triplicates. 2.5. Scanning Electron Microscopy analysis of scaffold: The scaffold was examined under scanning electron microscope (SEM) (ZEISS EVO 18) under acceleration voltage of 10 kV. The uncoated sample was used for SEM…

Levofloxacin cocrystals were prepared by solvent evaporation method. The drug and co formers, stearic acid and sodium saccharin were physically mixed in varying ratios of 1:1, 1:3, 1:5, 1:7 and 1:1 and 2:1 respectively in a glass mortar and the mixtures were dissolved in ethanol as solvent for crystallization. The solvent evaporation was carried in rotary flash evaporator (Laborota 4000, Hiedolph) maintained at 40 ± 2ºC and speed of 30 rpm. The products obtained were dried in a desiccator and…

3.2 Analysis of chip formation Fig. 7 shows the chip forms obtained during milling of the Al7075 (a) and MMCs (b) using the uncoated carbide inserts at a feed rate of 0.1 mm/tooth, machining speed of 290 m/min and axial depth of cut of 1.3 mm. The Al7075 chips formed during milling exhibited a smooth and shiny surface, and were in a semicircular and parabolic trapezoidal wave with a small radius and a saw-tooth-form, as shown in Fig. 7 (a). Fig. 7 (b) shows the chip shapes formed during the…

Background and Education Plans The end, or reason, for my life is something that had intrigued me early in life. As a child, I began to consider the origins of my name and learned that “Alexis” was derived from the ancient Greek word Alexos – which means, “to defend.” Through personal experiences and contemplation, I have made it my firm conviction that the end, or purpose, of my life is to defend and be of service to the people. My career objectives include completing my Bachelor’s degree…

3.1.3 FESEM and EDS analysis The structural morphology of the Pure HA, Sr-doped HA, La-doped HA and La/Sr co-doped HA (different La concentrations of 0.03, 0.06 and 0.1M) nanoparticles are analyzed by FESEM images are shown in Fig. 3 (a)-(f). The morphology of pure HA shown in Fig 3 (a) indicates that formation of spherical (or) chain pearl shape of nanoparticles, ranging from 70 to 84nm. Further, Sr (0.1M) doped HA and La (0.1M) doped HA belongs to Fig.3 (b)-(c), appears the formations of few…

activity of a chloroplast electron transport chain. The two choices that were available for us to investigate was broccoli and pea seedlings. Our group was nominated to utilize 20 grams of broccoli florets to find fractions that composed of an abundance of chloroplast. Project 1 had 3 parts to it; this consists of fractionation of cell homogenates, assay for chloroplast-specific electron transport chain activity, and testing factors that affect activity of the chloroplast electron transport…

ATP synthase is completely reliant on the generation of a proton gradient by the electron carriers in the membrane, such as quinine or cytochromes. Further to this it has been shown that both active and latent mycobacteria are reliant on the ATP generated by ATP synthase, and therefore an ideal target is to affect the proton gradient…

Transient neonatal myasthenia gravis is a human model of passively transferred MG. I a study conducted by Tzartos, S. J., Efthimiadis, A., Morel, E., Eymard, B., & Bach, J. (1990), fine antigenic specificities of anti-AChR antibodies in sera from 21 MG mothers and 17 of their infants were studied (nine of which had transiently transferred the disease). Although in a few cases significant differences in antibody specificities were observed between mothers and infants, whether myasthenic or not,…

Sulfamethazine remediation potential of Arabidopsis thaliana root ABSTRACT The use of antibiotics in animals either as a growth promoting or as a disease treating agent has become a worldwide trend. Antibiotics being stable bioactive compounds are not fully absorbed into the animal system and are released into the environment through animal manure. This study aims to discern the effect of one such veterinary antibiotic, sulfamethazine, on Arabidopsis thaliana root and also the possible…

GENE REGULATION: Gene regulation is the method of limiting the genes in the cell’s DNA, which are expressed. It is utilize to form a functional manufacture for an example protein. Various cells in a multi cellular organism might express very difficult group of genes. Although, they consist the similar DNA. Human having over ten thousands of genes in their genome. Cells are expressed the all genes. Even an organism as simple as bacterium must carefully regulate gene expression. Ensuring that the…
