Insert the bit until the shank reaches the bottom of the collet, back it out about 1/16" to 1/8" and then tighten the collet. • Make sure the bits are sharp, smooth and clean Sharp and clean bits help the operation run smoothly and produce good results in a safe way. Dull bits result i a lot of tear-out, not precise cuts. Remember to clean up resin buildup and remove small nicks in the cutting edges for optimal
Fundus Camera Reticle Setup (Mydriatic) An often overlooked and critical step in obtaining sharp images is to set your reticle. The reticle is the adjustable viewfinder crosshairs and is unique to each operator’s eye visual acuity. To adjust, place a white piece of paper in front of the camera (alternatively, you can use the camera lens cap on), raise the illumination light to highest and while looking through the viewfinder, turn the eyepiece clockwise and counter-clockwise until crosshairs are sharpest. You are now setup. Fundus Photography (FP) To begin, it is standard to start all Fundus photography with the right eye (OD) followed by the left eye (OS).
Apply nail varnish to the leafs surface. 4. When the nail varnish dries, peel off the layer of nail varnish using sellotape and place it on a transparent slide. 5. Look at the layer of varnish using a magnifying glass and mark the stomata using a think marker.
The image formed is said to be real because the rays of lighted from the object pass through the film and inverted (upside down). (Passmyexams.co.uk, 2018) Concave always produce images that are virtual, upright and diminished (smaller) in size compared to the object. The image always appears to come from the same side of the lens as the object. Ray diagrams for diverging lenses follow similar conventions to those for converging lenses, but how the location of the image is determined is slightly different.

The imaging techniques can damage the live cells. Handling and labeling the samples must be performed carefully to avoid toxicity. Advances in microscopy instrumentation such as cameras, filters, illumination devices and using shutters to stop the excitation light when not in need, makes imaging live cells n crucial approach for today
A properly made thin film is consists of an unbroken layer of red blood cells with the 'tongue' of the film not touching the edge of the slide. The thin film is dried immediately by waving the slide from side to side or by holding it for a few seconds in front of a fan which ensures a good preservation of the shape of the cells. Staining : 1. Air-dried films are placed on a level staining rack. 2.
Resolution (resolving power) is the ability of a microscope to differentiate between two points. The resolution became better if the wavelength of the illumination is shorter. The white light used in a light microscope limits resolving power to about 0.2μm. The lenses which are closest to the specimen are the objective lenses. For the highest magnification, it is necessary to use oil immersion.
It is possible to focus the microscope on this upper surface by focusing on a piece of dust on the lens. The side of the plano-convex lens with curvature was easily identified by placing it on a flat surface and pressing downwards on its outside edges, if it wobbled when pressed this suggested it was on the curved side. It was necessary to do this as the experiment requires that the curved face be in contact with the optical flat. The mount containing the glass plate, optical flat, and the plano-convex lens was moved until the centre of the fringe was at the intersection of the cross hairs of the microscope. The central dark fringe of the produced interference pattern is the
Make your cuts as straight as possible, with enough room to add the PVC connector reattaching the pipes when you are finished. Remove the top mount multiport by pulling upwards, keeping track of the (usually bright blue) o-ring. You may have to wiggle it a little since it is slotted into a plastic pipe coming up from the bottom of the
You can also use a multi-use brush made of brass wire for buffing up the nap of the material • Tag it along with a polish or conditioner to give colour and shine to your shoe • Allow the pair to de-odorize and retain its natural shape by rotating the shoe every day • Do not leave your shoes out in the open sun to prevent the colour from fading • If your loafers get wet, then let it dry naturally in shade and treat water marks, if any, only when completely dry • Use shoe-tree to soak up extra moisture and also to retain shape • If you get mud on your loafers, leave it to dry before brushing the mud-off • Using shoe bags would shield the delicate loafers from absorbing atmospheric moisture and, protect it from developing mildews • Do not use any harsh chemical. This may harm both the colour and
