“If you look at the evolution and leap forward to 11 years from now, I think we will be using all the knowledge in molecular biology, and cancer biology combined with imaging, It will be images, combined with genes, tumor markers and patient data.” (Liselotte Hojgaard, MD, professor of medicine and technology at the University of Copenhagen) The science of radioactivity has existed for many decades since it’s discovery. While often perceived as a risky and dangerous practice, artificial…

The CGS framework retreats to a proposition in 1832 by the German mathematician Carl Friedrich Gauss to base an arrangement of supreme units on the three essential units of length, mass and time. Gauss picked the units of millimeter, milligram and second The centimetre–gram–second arrangement of units (truncated CGS or cgs) is a variation of the metric framework taking into account the centimeter as the unit of length, the gram as the unit of mass, and the second as the unit of time. All CGS…

the higher the absorbance value will be. A reason for this is because light absorbance is related to color, as well as, concentration, in that, when the light passes through the sample of material, (in this case a mixture of eosin and water), the photons of light hit molecules of the mixture and it then dissipates, thus increasing the absorbance. The wavelength used for this…

I think this title is asking me to break down the quotation, “In gaining knowledge, each area of knowledge uses a network of ways of knowing,” and to analyse the validity of the argument that to gain knowledge, each area of knowledge uses a network of ways of knowing, with reference to two areas of knowledge. There are several key words in the quotation that need to be defined. First, the word “gain” implies progress and advancement or benefit toward gaining knowledge. I will focus my essay on…

In the human body, nearly 70 trillion cells work simultaneously with one another to maintain order throughout the designated body system (Zimmer, C., 2013). However, occasionally mutations occur in the deoxyribonucleic acid (DNA), causing catastrophic events to occur throughout the body. Once these mutated cells have replicated and begin to take over a specified region, the mass then begins to absorb the region’s main source of nourishment: the blood supply. This is known as cancer. Each year,…

Elekta Synergy S linear accelerator (LINAC) was used to produce the 6, 10, and 15MV photon beams for measurements. The accelerator is fitted with the new Agility multileaf collimators (MLC) thinner than the previously used MLC’s to improve a field definition (Kantz et al. 2015; Thompson et al. 2014). The quality assurance was carried out monthly to ensure the LINAC response does not vary from the commissioning data (CPQR 2013). The LINAC has been calibrated to 100 cGy/MU at Dmax for a 10×10 cm2…

Therefore, the first half of the creation week does not necessarily proceed along the lines which some insist. The only solution to this difficulty would be to interpret the text as saying that the Sun appeared on the fourth day, but that it had actually been created on the first and was therefore the source of the light which separated day and night. This is something which the adamantly literal interpreters refuse to do. In critiquing Hugh Ross for suggesting such an arrangement, Terry…

attempt to destroy the tumor and stop the cancer cells from growing out of control. Radiation can damage the DNA directly or indirectly as its application creates free radicals within the cells. Interactions involving cell killing in the realm of photon radiation therapy are mostly due to indirect damage. Free radicals are molecules with unpaired electrons, leading them to be unstable and react quickly with other compounds to gain stability, which causes a chain reaction that eventually damages…

ISE SUMMER PROJECT 2015 Probability, randomness, and chance should be central in any STEM pedagogical model. The concepts of randomness and chance play a very significant role in the essence of all sciences, and especially in the empirical sciences. Randomness is a critical component of biological modeling at many levels in a wide range of systems. The fundamental axioms of the quantum paradigm in physics are, by definition, essentially stochastic. Economics uses the randomness in human thought…

the sun converts hydrogen atoms into helium creating colossal amounts of by-product in the form of energy the radiates onto earth and beyond the solar system. This radiation energy can be harnessed with Photovoltaic cells. This happens when the photons from the sun are absorbed in the photovoltaic cell’s semiconductor, they release electrons. These electrons can be captured through electric conductors and alternatively be stored in batteries when not in use. This energy can serve a plethora…
