MICROBIAL SURVEY‚ SMEAR PREPARATION‚ AND SIMPLE STAIN Instructional Objectives 1. Define Roccal = green‚ liquid disinfectant. Pathogen = an agent which causes disease. Wet Mount Slide = a microscope slide of a liquid specimen covered with a cover glass. Yeast = a single celled fungi. Budding = a true characteristic method of asexual reproduction among yeasts where budding of a new cell from a parent cell can be observed. Mold = multicellular masses of filamentous fungal growth.

the sample with quick cool was made melting the bulk material and then slow cooled as the sample II‚ after this the sample was melted again and quickly cooled using liquid nitrogen (sample III). Those samples were analyzed by Scanning Electronic Microscopy to characterize the composition‚ as well as see the pattern of phases in the alloy. Keywords: Aluminum Copper‚ Phase Diagram‚ Cooling rate‚ SEM‚ XRF. Introduction The microstructure of the material plays a fundamental role at the mechanical

the number of yeast cells per cm3 that counted using haemocytometer under microscope. Aim To investigate the effect of the different dilutions of yeast cell suspension on the number of yeast cells per cm3 that counted using haemocytometer under microscope. Research Question Do the different dilutions of yeast cell suspension affect the number of yeast cells per cm3 that counted using haemocytometer under the microscope? Introduction “The typical yeast cell is approximately equal in size

Onion Distilled Water Apparatus: Microscope Microscope slides & cover slips Tile Knife Tweezers Pasteur Pipettes Assignment: I was given the onion once it had been chopped up on the tile‚ ready for me to peel back the skin I required using the tweezers. I then placed piece of onionskin onto the microscope slide‚ making sure there were no folds or creases‚ and put a drop of iodine onto the slide as well‚ to view through the microscope. On my first try the onion folded so I

phase stabilityand electrical performance in the parent bismuth vanadate and was investigated by combining results obtained fromPowder X-ray diffraction (PXRD)‚ Differential Thermal analysis (DTA)‚ Thermogravimetric analysis (TGA)‚Scanning Electron Microscopy(SEM) and AC impedance spectroscopy. The PXRD results show that the composition x= 0.05 and 0.07 have monoclinic while for x= 0.10 orthorhombic symmetry. Composition x ≥ 0.15 presents a tetragonal symmetry. The thermal analysis revealed the existence

surgical operating microscope in dentistry was done as early as 1986 by selden‚ it was no until the early 1990’s that the DOM was introduced into the profession and graduate level endodontic programs. These revolutionary instruments have taken endodontic surgery to another level of sophistication “the microsurgical approach”. Microsurgery is limited to a surgical procedure on exceptionally small and complex structures with the aid of an operation microscope. The microscope allows the minimizing

If you’re familiar with copper cable‚ you’ll quickly discover that fiber optic cable is a completely different animal. Not only is the installation process different for fiber‚ but also the troubleshooting process. Fiber optic cable is also far more fragile than copper cable‚ so there
