Ionizing radiation

The world is full of a multitude of colors that are used for both practical and aesthetic purposes. The colors that are seen when looking at different objects are due to the ability of the compounds in those objects to absorb specific wavelengths of light. In other words, the colors that are seen are the ones that are not absorbed. The wavelengths of light that are absorbed are determined by the electrons in a compound.1 As electrons move around, they can absorb energy and become excited. The…

The therapeutic properties of qigong have been found to improve the regulation of the respiratory system, improved the physical function of the body’s self-control, and boosted the massaging effect on the abdominal cavity organs, served to correct the abnormal organ reactions, and improved the activities of the cardiovascular system, central nervous system, cerebral cortex and regulated the metabolism process. Additionally, practices on qigong have shown a considerable amount of improvement in…

the ionic charge, it cannot exit from the cell unless it decays. So, the radiolabeling of tissues with high glucose uptake is enabled with the using of FDG-PET. Some other examples of glucose-using cells are brain and liver. Usually, the effective radiation dose is…

summer days. The advanced fabric would aloe IR radiation to escape through the fabric easily, and prevent the body from overheating. Furthermore, researchers have produced a nanoporous fabric that can release body heat, instead of…

Tzvat is a city in the Northern District of Israel. Located at an elevation of 2,953 feet, Tzvat is the highest city in the Galilee and in Israel. Due to its high elevation, Tzvat experiences warm summers and snowy winters.Tzvat is a famous vacation spot for its mild climate and scenic views. Tzvat’s current mayor is Ilan Shohat. In 2016, it had an estimated population of 33,636 residence. Tzvat is known as one of the four holy cities along with Jerusalem, Chevron, and Tiveria. It is mentioned…

Spectroscopy is the study of how matter and electromagnetic radiation interact with one another. In this experiment, we are observing and recording the emission of photons with wavelengths on the visible light spectrum. To understand…

Introduction: The ability of substances within a solution to absorb light is a wonderful phenomenon as it aids in processes such as determining the concentration of proteins. The way that a solution absorbs light is due to the photoelectric effect. The way the photoelectric effect works is that when light comes in contact with the sample, the photons of light will react with its electrons. As the light travels through the solution, "a photon of light may interact with an electron ... [where]…

Astronomy Practical – Carey Zimmer The aim of this experiment is to verify the inverse square law involving the light from the globe of an optics kit (The star) and a light meter placed some distance away. This is to be done by analysing the relationship between the source and the detector. Hypothesis: If the distance between a light source and a light meter increases, then the amount of Lux recorded on the light meter will decrease. Materials: • Light box kit • Power supply • Meter ruler •…

Slow, sleepy, Sunday mornings are the best with you. Your little toasty toes pitter across the floor while you linger closely at my heels babbling in a language only you could ever understand. With my coffee in hand we begin our day. Mundane tasks of laundry and dishes turns into your adventure of, "How much of a mess can I make?" You always seem to be right under my feet and I'm tripping. I'm tripping and falling. Falling -in love- with you. Dearest Daughter, I see myself in you. Today you…

Session on surgery, radiation therapy and chemotherapy are the conventional treatment options for cancer therapy. To maximize the killing effects to the tumor, the combination therapy with surgery and radiation, or chemotherapy are most often used (Tannock 1998). However, for treatment of small, poorly defined metastases or tumors embedded within vital regions, such as brain, conventional treatment options may not be able to provide effective therapeutic outcome (Hirsch, Stafford et al. 2003).…
