Virologist

 Virologist

is the study of viruses. Submicroscopic, parasitic particles of genetic material contained in a protein coat and virus-like agents. It focuses on the following aspects of viruses: their structure, classification and evolution, their ways to infect and exploit host cells for reproduction, their interaction with host organism physiology and immunity, the diseases they cause, the techniques to isolate and culture them, and their use in research and therapy. Virology is a subfield of microbiology.

 

A major branch of virology is virus classification. Viruses can be classified according to the host cell they infect: animal viruses, plant viruses, fungal viruses, and bacteriophages. Another classification uses the geometrical shape of their capsid or the virus's structure.

 

As most viruses are too small to be seen by a light microscope, sequencing is one of the main tools in virology to identify and study the virus. Traditional Sanger sequencing and next-generation sequencing (NGS) are used to sequence viruses in basic and clinical research, as well as for the diagnosis of emerging viral infections, molecular epidemiology of viral pathogens, and drug-resistance testing.

 

The word virus appeared in 1599 and originally meant "venom".

 

Viruses are bacteria. Viruses are grown.

Radiology is the medical discipline that uses medical imaging to diagnose and treat diseases within the bodies of animals, including humans. Radiologists are medical doctors that specialize in diagnosing and treating injuries and diseases using medical imaging (radiology) procedures (exams/tests) such as X-rays, computed tomography (CT), magnetic resonance imaging (MRI), nuclear medicine, positron emission tomography (PET) and ultrasound. a radiologist completes about 13 years of training after high school. In addition to this training, there are two exams to successfully take to become certified by the American Board of Radiology. Some subspecialties of radiology must be chosen during the residency period. Becoming a radiologist can be a very rewarding career. A day in the life of a radiologist may include all of the tasks above, which could be specialized into a specific area of radiology. If you're considering entering this career field, it may be a good idea to understand the tasks of the job first. The required education for a radiologist includes a four-year college degree, medical or osteopathic school and at least four years of residency training. In addition, all radiologists must fulfill the examination requirements for state licensing. Essential skills Attention to detail. Ability to work as an individual and as part of a medical team of specialists. Excellent communication skills. Able to work well in stressful conditions. Critical thinking. Extensive knowledge of and an aptitude for the medical profession.

 Quantum_mechanics is a fundamental theory in physics that provides a description of the physical properties of nature at the scale of atoms and subatomic particles. It is the foundation of all quantum physics including quantum chemistry, quantum field theory, quantum technology, and quantum information science.   science dealing with the behaviour of matter and light on the atomic and subatomic scale. It attempts to describe and account for the properties of molecules and atoms and their constituents—electrons, protons, neutrons, and other more esoteric particles such as quarks and gluons.   counter-intuitive phenomenon predicted by quantum mechanics is quantum tunnelling: a particle that goes up against a potential barrier can cross it, even if its kinetic energy is smaller than the maximum of the potential.[7] In classical mechanics this particle would be trapped. Quantum tunnelling has several important consequences, enabling radioactive decay, nuclear fusion in stars, and applicat

Energy

 Energy in physics, the capacity for doing work. It may exist in potential, kinetic, thermal, electrical, chemical, nuclear, or other various forms. There are, moreover, heat and work—i.e., energy in the process of transfer from one body to another.   For the potential energy the formula is P.E. = mgh   The different types of energy include thermal energy, radiant energy, chemical energy, nuclear energy, electrical energy, motion energy, sound energy, elastic energy and gravitational energy.   The formula that links energy and power is: Energy = Power x Time. The unit of energy is the joule, the unit of power is the watt, and the unit of time is the second.   Wasted energy is energy that is not usefully transferred or transformed. Energy cannot be made or destroyed. ... The energy that is not used in this process is wasted energy. For example lighting a light bulb uses electrical energy to make light energy which is useful.   While energy can come in many different types, there are onl
