Abstract— Optical Pulse Oximetry is feasibly the greatest advance in patient monitoring. Pulse Oximetry enables oxygenation, an important physiological variable that is poorly detected by clinical means, to be monitored continuously and easily. Hypoxemia is commonly found in all aspects of medical practice and is a major cause of organ abnormality and death. It should be widely available and used routinely in clinical practice both in primary care and in hospital. This paper will design a…

At this point, it is important to note that, this particular orientation of rhodopsin in the microvillar membrane which gives selective sensitivity to polarized light by itself is not sufficient to analyse the sky 's polarization. An interesting analogy to spectral vision may be stated at this point to make this concept clearer, just like how it would be impossible to detect various colours if only one colour pigment was present, it is equally impossible to analyse the sky 's polarization if the…

Sound is an amazing spectacle, it is a thing that is made up of vibrating waves that move up and down back and forth. Two ways to think of sound in a real life example are: 1st a slinky; the way it jiggles back and forth is much like how a sound wave can jiggle, 2ond a water wave; the way that the wave looks much like a squiggly horizontal line that is what sound waves act much like. A vibration, A.K.A the up and down slinky motion and the to and fro water wave motion, are called vibrations. A…

Experiment #6: Polarimetry Resolution of (∓)-Racemate: (∓)-ɑ-Phenylethylamine OBJECTIVE All chiral molecules have a mirror image of themselves. While they have the same physical properties, they interact with other chiral molecules completely different. Since there are many chiral molecules in organics, this can lead to the need to make optically pure products. If the chemist does not, it can lead to many problems including death. In this experiment, the separation of two enantiomers was…

particles of a medium. Some waves must travel through matter, known as the medium (mechanical waves). And when they travel through the medium they cause the particles to vibrate. Some types of mechanical waves are sound waves and ocean waves. Electromagnetic waves, on the other hand, are waves that do not need to travel through a medium. They are disturbances in both the electric and magnetic fields. These waves can travel through a vacuum (empty space) because they don't require a medium to…

Introduction The microscope is an optical instrument that produces large images of small objects that cannot be observed by the human naked eye. There are two types of light microscopes: compound microscope and Electron microscope. Light microscopes are divided into two categories: Compound microscopes and Stereoscope microscopes. Electron microscope functions in the following way; a stream of electrons emitted from an electron source built in the microscope, the obtained image is in black and…

atomic Cadmium lamp. The part of the spectrum observed will be the 645nm (red) emission line. Electrons occupy energy levels within an atom when a photon of energy hf is absorbed by an electron in the n=1 level and if the energy is such that the electron is excited and ascends to the n=2 level after some time the electron will then descend back to the n=1 level and a photon of hf will then be emitted again. Each atom has its own unique absorption and emission spectrum this is because each atom…

SHAH How to do HDR photography (lions) HDR Photography HDR (High Dynamic Range) photography is a form of image processing that uses a series of images captured at different exposures to produce one, amazing photo. The dynamic range is a term used to infer to the ratio of darkness to the light. The idea is usually to compress the compress the light and have it appear on the final processed photo or computer in the same manner the eyes sees it. According to Photography.TutPlus, a good digital…

Visual acuity Main article: Visual acuity Visual acuity is the eye's ability to detect fine details and is the quantitative measure of the eye's ability to see an in-focus image at a certain distance. The standard definition of normal visual acuity (20/20 or 6/6 vision) is the ability to resolve a spatial pattern separated by a visual angle of one minute of arc. The terms 20/20 and 6/6 are derived from standardized sized objects that can be seen by a "person of normal vision" at the specified…

Diagram of Prototype A that consisted of an octagonal prism with a length of 11 in. or 27.94 cm. and height of 10.16 cm., while we created corrugated layers within the prism. We decided to change all the dimensions to centimeters instead of using inches as the units. Tinkercad model of Prototype B that consisted of a hexagonal prism with a length of 27.94 cm., height of 10.16 cm., and sides of the base of 4.445 cm. WIthin the hexagonal prism consisted of 6 equilateral triangles are connected…
