A microscope (from the Ancient Greek: μικρός‚ mikrós‚ "small" and σκοπεῖν‚ skopeîn‚ "to look" or "see") is an instrument used to see objects that are too small for the naked eye. The science of investigating small objects using such an instrument is called microscopy.Microscopic means invisible to the eye unless aided by a microscope. There are many types of microscopes‚ the most common and first to be invented is theoptical microscope which uses light to image the sample. Other major types of microscopes

Definition of the parts of the microscope 1. Stage The horizontal surface upon which the slide is placed is called the stage. The slide is held in place by spring loaded clips and moved around the stage by turning the geared knobs on the stage. Th stage has two perpendicular scales that can be used to record the position of an object on a slide. This is useful if you want to quickly relocate an object. 2. Coarse adjustment The coarse adjustment knob located on the arm of the microscope

1) The condenser lens concentrates light and makes illumination of image more uniform. 2) The bending of light is also known as refraction. 3) Total magnification = ocular lens magnification x objective lens magnification. 4) The total magnification of an image is 1200x and the magnification of the ocular lens is 10x. What is the magnification of the objective lens? Y = objective lens 1200x = 10x X y 1200x / 10x = y y = 120x Objective lens magnification = 120x 5) The limit of resolution

Step Down DC to DC Converter Ivana Krezzel T. Almazan and Ruphina G. Gomez Introduction In our world today‚ cellphones‚ and laptops are widely used. For some‚ these things are so important especially for students and employers who work from office. These devices are usually operated with battery. A DC to DC converter is an electronic circuit which converts a source of direct current (DC) from one voltage level to another. DC is not easily being stepped up or down. One of the applications

inevitably lead to illness‚ poverty and despair. A first step to changing habits is to realize that all behavior is unconscious and mechanical. We are creatures of habit. This is why behavior and thought patterns are not easy to change. The unconscious component can be very deep and very old. We need to understand this‚ and then we can change the bad habits. According to Wilson‚ the first rule is do not rationalize‚ defend‚ justify or excuse your bad habits- no matter what. Second is put out and express

a psychiatric illness develops his or her own definition of recovery. However‚ certain concepts or factors are common to recovery. Some of these are listed below. More recently‚ SAMHSA released a consensus statement outlining 10 fundamental components of recovery‚ which can be viewed here. Hope Hope is a desire accompanied by confident expectation. Having a sense of hope is the foundation for ongoing recovery from mental illness. Even the smallest belief that we can get better‚ as others
