more cell layers were added on top of them. The cell sheets were placed on 5 different pig hearts on the left ventricle either basal or apical side up, after 15-60min the sheets and heart tissue underneath were removed for analysis under a scanning electron microscope. The basal side adhered to the heart tissue better than the apical side, showing a solid connection with the heart tissue about 30 minutes after being inserted. During open heart surgery, the chest should remain open at least 30 minutes

Ballistics (B5) Literature Review Evaluation of the possibility of differentiation between various types of ammunition by means of GSR examination with SEM-EDX method (2001) This paper assesses the use of a scanning electron microscope with an energy dispersive x-ray spectrometer (SEM-EDX) to analyse gunshot residue (GSR) and determine the type of ammunition used, as well as the gun it was fired from. GSR is the remains of the primer and propellant from the ammunition after a gun is fired. GSR

Even though dental swept-source-OCT post-conditional observations on the caries lesion induced composite gap formations neglected to mention the possibility of treating these diagnosable injuries, Saito et al used demineralization at 0.1 M EDTA pH 7.4 at 4 °C to suggest Collagen/DPP composites as a therapy method which reverses the process of erosion by inducing natural dentin regeneration. In particular, Saito et al developed this suggestion through first preparing DPP cross-linked to type I Atelocollagen

capacity of NC-2 and NC-3 as compared to NC-1. Figure 6.8. Water uptake capacity (%) of NCs measured as a function of immersing time that determined the efficiency of samples as wound dressings to absorb wound exudates/fluids. 6.3.2.9. Scanning Electron Microscope (SEM) Images Documented the Porous Behavior of NCs The decrease in water uptake capacity of NCs from NC-1 to NC-2 and then NC-3 could be due

2.10 Literature reviews Alexandra et al, investigated the esterification of oleic acid with methanol by homogeneous catalyst that is 4-dodecylbenzesulfonic acid. Firstly, this catalyst was compared with sulfuric acid and p-toluene sulfunic. It was shown the result that reaction rate increased with increasing hydrophobic of the catalyst. Secondly, the effect of the parameter in esterification reaction was studied. It was observed that quantity of catalyst and temperature increase the reaction rate

Urea determination is of great interest in different fields as pharmaceutical and food industry, environmental protection, fertilizers, but the most important applications are in biomedical and clinical analysis. In fact, urea is a waste product of protein degradation and the main nitrogen component of urine, produced in the liver and eliminated by the kidneys. Some pathologies such as renal insufficiency, hyperpyrexia, hyperthyroidism, leukemia, burns, diarrheal diseases and diabetes mellitus are

A Century of Physics By the end of the nineteenth century after more than two thousand years of intellectual struggle that began with the Greek philosophers, physical scientists had reason to believe that they were beginning to understand the universe. Their theories of matter and energy, of electricity and magnetism, of heat and sound and light were confirmed in laboratories throughout the world with increasing precision. Experimentation was the method and mathematics the language of a

Surface morphology and topography was carried out by the Scanning Electron Microscope (ESEMQUANTA200, FEI-Netherland) and Atomic Force Microscopy (Agilent 5500) respectively. Elemental analysis was made by energy dispersive X-ray spectroscopy (attached to SEM). The optical properties of the films were examined with a double
