Linear Amplifer

What would be the effect of using an amplifer in the non-linear range with a sin wave in and distorted out?

You would not hear the clear single tone of a sine wave. Instead, you are changing the shape of the sine wave and creating a complex wave which is similar to multiple frequencies combining in and out of phase.
Depending on where you operate on the transfer curve, there is also the possibility of introducing clipping distortion where the peaks of your output will flatten out and increase the distortion.
Depending on what the amplifier is used for, this distortion can be good or bad. When using it to listen to most music, it is unpleasant. But when used for certain kinds of music like heavy metal guitars, then it is desired for special effects.

Flow Cytometry actually began as a simple device designed during World War II to identify bacteria in the defense against germ warfare. Today, people use flow cytometry to analyze cells and their kinetics, tumors, and cellular DNA content in a person. Flow Cytometry works that gives us the wonderful ability to measure the fluorescence and scattering factors of individual cells.

What a flow cytometer are not used laser light scattering of particles such as chromosomes, bacteria, cells, etc, and left molecules linked to fluorescent dyes. To work in the field of flow cytometry must have a great deal of knowledge and education. Flow cytometry is used in the medical field especially for the diagnosis health disorders such as cancer in the blood, however, also has many uses in joint research and many other medical practices. How works is, a beam of light from a single wavelength is directed towards a fluid stream, a number of detectors are aimed at the point where the current passes through beam of light, one is in line with the beam of light, and several perpendicular to it, with fluorescence detectors. Each particle that passes through the beam at some scattering how the light and fluorescent chemicals in the particles that emit light at a wavelength of the source of light.

The detectors collect combination of fluorescent light and scattered light. It is then possible to obtain different information about the chemical and physical structure of each particle. Is very difficult to understand and comprehend how the system works, that's why in order to be a cytometrist you must be very knowledgeable in the field. Today, cytometers that can examine thousands of properties of particles every second, and can separate particles that have been specified. A flow cytometer has five different components, a flow cell, a flow of fluid that carries cells that pass through the beam in one line. An optical system, more commonly used are round, low-power air-cooled and water cooled lasers, high power laser. A detector and analog-digital conversion system, which works by generating FSC and SSC, and fluorescent signals of the light used in electrical signals that can be processed by a computer, a system amplification, which means using linear or logarithmic, and the last one out of five is a team to analyze the signals that are transmitted through during the process. When people use a flow cytometer, collecting data and samples, actually is called acquisition. Early flow cytometers are devices experimental, but has made sufficient progress in recent years. Today flow cytometers have advanced and have many lasers and fluorescence detectors, that allows numerous antibody labeling and identifying more precisely in the investigation.

Remember when starting cytometry, there are a number of other areas which are regarded as the pathology, molecular biology, plant biology, immunology and marine biology. Cytometry also used in these fields, and that may be helpful, especially in the field of molecular biology, so it may help to know if not proficient with any information in other fields used cytometry.
