purpose of this lab was to see if radiation has an effect on the cultivated radish seeds that we used. From the observed data that we collected‚ we were able to conclude that when seeds are exposed to radiation‚ it affects how they grow‚ if there is any growth at all. Introduction Radiation is an important environmental abiotic factor for plants‚ and one small section of the electromagnetic radiation spectrum‚ is called the Photosynthetically Active Radiation (PAR)‚ provides the energy to

Primary radiation is also known as direct radiation. * Secondary Radiation (aka Scatter radiation & Leakage Radiaiton) * Scatter Radiation – results whenever a diagnostic x-ray beam passes through matter. * Compton interactions between the x-ray photons and the electrons of the atoms within attenuating object deflect x-ray photons from their initial trajectories. * X-ray photons emerge from the object in all direction. * Leakage Radiation – radiation generated

Blackbody radiation: a spectroscopic study John Greavu Partner: Nicholas Souhleris TA: Yilikal Ayino (Friday‚ Section 006) April 18‚ 2014 I. PRELAB A blackbody is a body that absorbs all electromagnetic radiation and emits a continuous spectrum‚ such as heated cavern with just a small opening to the outside world. In 1900‚ German physicist Max Planck derived an expression for this blackbody spectrum. Knowing that oscillators emit radiation‚ he assumed that oscillators within the cavern were

Electromagnetic radiation Electromagnetic radiation (EM radiation or EMR) is one of the fundamental phenomena of electromagnetism‚ propagating and traveling through space via photon wave particles‚ carrying radiant energy. In a vacuum‚ it propagates at a characteristic speed‚ the speed of light‚ normally in straight lines. EMR is emitted and absorbed by charged particles. As an electromagnetic wave‚ it has both electric and magnetic field components‚ which oscillate in a fixed relationship to one

In this report‚ the absorption of heat in white‚ black and silver will be explored. Infrared radiation is invisible radiant energy‚ it lies between the visible light and the microwave portion of the electromagnetic spectrum. Heat is the main source of infrared energy‚ heat is produced by the movement of atoms and molecules. This experiment was conducted to investigate how black‚ white‚ and silver cans would absorb heat. The electromagnetic spectrum is made up of gamma rays‚ X-rays‚ ultraviolet‚

which is where therapy comes into the picture. There are many different types of therapy‚ two of which are occupational therapy and physical therapy. These two branches of rehabilitation are very similar and often confused‚ but they are not the same. Physical and occupational therapies often work together and overlap on their treatments. Even though they intersect the therapists are usually looking for a different outcome. The difference in outcome is what makes these two types of therapy crucial to

What is targeted cancer therapy. Target cancer therapy is a new type of cancer treatment that is still on the come up. This treatment uses drugs or other substances. It takes advantage of differences between cancer cells and normal cells‚ targeted therapy is a special type of chemotherapy. Other cancer treatments are used with targeted therapy‚ but often used on its own. Targeted therapy drugs dont work the same way as standard chemotherapy drugs. Many targeted drugs will tend to go after the cancer

Holding Therapy What is Holding Therapy? Holding therapy was developed by Dr. Martha Welch in the late 1970s. Dr. Welch was a psychiatrist in New York who began using it with children with autism. Later‚ she outlined her form of therapy in a book titled‚ Holding Time (Welch‚ 1988). Originally‚ Dr. Welch discovered holding therapy with autistic children. Later‚ however‚ she began using this therapy with typical children as well and‚ in her opinion‚ discovered equally satisfying results

Humanistic Therapy Gregg D Black Psychology as a science is not thought of as being integrated. The schools of thought are wide and varied each with their own perceptions. The Humanistic approach to therapy is one that I believe has merit when applied to specific disorders. Humanistic therapy directs the patient to center their attention on their; motivations‚ values‚ emotions and meanings behind their thoughts and actions. The belief is this will bring about a desired change both consciously and
