Contrary to the title, the discovery of astatine was anything but a momentary process. Many scientists discovered different astatine isotopes, atoms with the same number of protons but differing numbers of neutrons, but were unable to either reproduce their results or keep the isotope in existence for any useful amount of time. After decades of possible discovery and rediscovery, astatine was officially included in the periodic table of elements with the abbreviation At and an atomic number of…

Osteosarcoma is a relatively radioresistant Tumor. Thus, adjuvant chemotherapy and surgery have been the backbones of treatment. Prophylactic whole lung irradiation was utilized in the late 1970s as a method for decreasing lung metastases post-operatively (Breur, Cohen, Schweisguth, & Hart, 1978). Prebiopsy Low-dose irradiation (around 10 Gy) can be given before the initial biopsy in order to decrease the viability of the malignant cells that can be disseminated into the circulatory system…

technology of mapping the brain can predetermine irregularities in the brain such as frontal lobe damage (p.26). Computer axial technology (CAT) scans combine with information on X-Ray, and Magnetic resonance imaging (MRI) depicts a three-dimensional view of the brain in doing so, a very detailed image of the brain which illustrates areas within the brain that is damaged or diseased (Gaines and Miller, 2011, p.27). Furthermore, a positron emission tomography (PET) scan aids in researchers being…

One of the finest blessings of solar energy is that humans are by no means going to run out of this large electricity aid even for millions of years. That is not something we possibly can say for oil, coal, petroleum, and different fossil fuels that humans have been dependent on for thousands of years. If people need to save the earth from raising carbon-emission gases, pollutants of water, and even global warming, they ought to change the electricity sources they use at present. Seeking more…

decreased to 80% and 71% for aqueous CR of 1x10-4 M and 1x10-3 M concentrations respectively. The decreased degradation of the dye with increasing concentration may be due to (a) high dye concentration may act as an inner filter which shunts the photons away from the LDH surface, (b) may lead to the non-availability of oxidative free radicals associated with the degradation process and (c) most of the dye molecules get adsorbed on the LDH surface blocking the active surface sites in the LDH. The…

<<>> “Medicines cure diseases, but only doctors can cure patients.” Carl Jung Personalized Cancer Treatment EuroMed’s medical staff has been treating cancer since 1991, and they’ve adopted an integrative medical approach, combining conventional and alternative treatments. Their principal belief is that cancer treatment must not be used at the expense of the patient’s immune system, so EuroMed Foundation utilizes an integrative treatment philosophy with an emphasis on maintaining…

The excerpts from Annie Dillard’s An American Childhood and Barbara Ascher’s Dancing in the Dark tell of their feelings both past and present about their experiences when going through the adolescent periods of their lives. Dillard and Ascher write in different styles overall but still use some of the same schemes and tropes of rhetorical grammar. Dillard favors long sentences full of commas and semicolons as she tries to fit as much detail as possible into each statement. Most of her sentences…

Epilepsy and the Oral Cavity Epilepsy is a central nervous system disorder (neurological disorder) in which nerve cell activity in the brain becomes disrupted, causing seizures or periods of unusual behavior, sensations and sometimes loss of consciousness (MayoClinic). Diagnosis of epilepsy is not an easy task as it comes in many forms and can range anywhere from a blank stare to full body convulsions, but once it is diagnosed, epilepsy can often be treated with medication and the patient can…

Light synthesis principles The basic idea of light waveform synthesis can be described as follows: First, the spectrum of a light waveform is decomposed into its constituent spectral components by a disperser, then, adequate modulators acting on each of this spectral components individually modifies the relative phase (or delay), the amplitude and polarization of these components before they are coherently superimposed again by a combiner to create a desired tailored waveform (Figure 2a)41.…

The Importance of Effective Workflow in The Medical Imaging Department The imaging department consists of many integrated systems that all play a vital role in the operation of the unit. These systems include RIS/HIS systems, modality interfaces, PACS systems, and integrated work systems. The efficient image acquisition and workflow are essential in today 's radiologic environment. These systems will be reviewed and their importance discussed as they tie into the workflow of the radiology…
