Introduction

Emergence of image guidance technology
Today’s computer-aided healthcare technology relies on much modality medical image and multimedia information. An image-guided radiation therapy was introduced due to the ever-increasing challenges originating from fast growth of the information technology sector and the global expansion of healthcare needs. Image guided technologies aid in the effective management of patients in the areas of detection, diagnosis and intervention. The image guidance technologies is a process that uses frequent imaging during a radiation therapy in order to improve accuracy and precision in delivering of treatment (Peters & Cleary 2008). Before the introduction of image guidance technology, ...

The article under consideration is “Radiation technologies: past, present and future” by A.G. Chmielewski and M. Haji-Saeid (2004). The research in question is devoted to the problem of radiation and its sources. The authors dwell on the historic background of studying the issue as well as on more recent findings in the sphere.
X-rays and natural radioactivity were discovered as early as in the XIXth century. Very soon after that, Marie Curie-Sklodowska and her husband proved the action of radioactivity on living organism and materials. Since that time the study of radiation effect has not stopped. Nuclear reactors producing ...

Introduction

Irina Tumilovich Rapsi’s article, Possible Risks of eBay of Chelyabinsk Meteorite Fragments, explores the legal aspect of selling the meteorite fragments from the meteorite that fell in Russia’s Chelyabinsk Region in mid- February. The author gives the arguments that have surrounded the controversial issue. It includes different legal views from different professionals who feel that the court as well as the Russian government should determine the sale of the fragments. Among the determining factors is the potential risk to human health due to the possible presence of radioactive elements in the fragments.

My Great-Great-Aunt Discovered Francium. And It Killed Her

The scientific discoveries that were made in the past were without any doubt full of risks and repercussions associated with the exposure to the radioactive materials that resulted in the damage to the bodies and over exposure to radiation led to the death of the researchers. Some researchers were enthusiastic about discoveries that they tend to ignore the long-term repercussions they may have to face due to their exposure to toxic materials, and Marguerite Perey was one of them. She mixed in different materials and ingredients and applied different theories without any care and concern regarding the contamination of ...

Introduction

In multicellular organisms, the cell divisions occur under the control of strict control of internal and external signals. However, cancer involves an uncontrolled growth of cells. The branch of medicine that deals with the study of cancer and tumors is known as oncology. A tumor is an abnormal mass of cells that may be benign or malignant. Benign tumors do not spread to other parts of the body while, malignant tumors can spread from the original site known as the primary site to other organs establishing secondary tumors.
According to their tissue of origin, cancers are classified as ...

Polyvinylidene fluoride polymer first exhibited the piezoelectric effect in the year 1969 followed by the pyroelectric effect some years later, leading to the development of numerous applications of pyroelectricity and piezoelectricity. PVDF possesses many attractive features as a tactile or touch sensor. Tactile sensors can be used to monitor skin conditions. They find use in minimally invasive surgery. Tanaka et al. developed an active palpitation sensor to detect hypertrophy and prostate cancer. Pyroelectric and piezoelectric polymers help in energy conversion. The Energy Harvesting Eel device created by Taylor et al. used piezoelectric polymers for the conversion of mechanical flow energy ...

Cocherova, Elena, Gabriel Malicky, Peter Kupec, Vladimir Stofanik, & Jozef Pucik. "Evaluation of Resonance Properties of the Human Body Models Situated in the RF Field." Advances in Electrical and Electronic Engineering[Online], 10.5 (2012): 345 - 349. Web. 7 Mar. 2013
Application of radiofrequency (RF) is becoming increasingly common in the development of medical therapies. One of the main concerns is the possibility for unwanted side effects. In this regard, temperature effects are perhaps the most commonly described. These effects are mainly attributed to the absorption of the RF field by human tissues. Estimating experimentally the impact of ...

Mammography Adherence: A Qualitative Study (Watson-Johnson et al., 2011).
Mammography is a procedure that entails using radiation for early detection of breast cancer in women to facilitate proper management after diagnosis. Despite its proven efficacy in reducing breast cancer-related deaths and a pronounced increase in its use among women between 1987 and 2000, a sharp decline has been noticed in adherence to its continued use. Watson-John et al. in this study aims at uncovering the cause of this sharp decline in usage of mammography by various categories of women who have used it in the past.
In designing the methodology ...

Thong, Haw-Yueh, and Howard I. Maibach. "Global Warming And Its Dermatologic Implications." International Journal of Dermatology 47 (2008): 522-524. Print

Written by Haw-Yueh Thong and Howard I. Maibach, the article ‘Global Warming and its Dermatologic Implications,’ seeks to demystify the topic of global warming and how it relates to dermatology. The article begins by identifying scientific claims of the role of greenhouse gases like carbon dioxide, methane, chlorofluorocarbons, and nitrous oxide in increasing global temperatures and leading to general climatic shifts. The article outlines its presentation under three major areas; ‘Global warming and the UV exposure of human ...

A drought that occurred in 1988 over North America sparked scientists to suggest theories as to what caused the phenomenon. From this, studies spawned as to what we can now relate to as “global warming”. According to Congress and the United States Administration, global warming is caused by a build-up of greenhouse gases such as; carbon dioxide, nitrogen oxide, methane and chlorofluorocarbons. This was the stepping stone to more studies and theories on greenhouse gas and global warming.
The greenhouse effect is a natural occurrence that allows ultraviolet radiation to pass on the surface of the earth and blocks infrared ...

Purpose of the article

The article seeks to find out the average energy that is required for every scintillation photon as well as the energy resolutions present in crystals of sodium iodide that is activated with thallium and cesium iodide that is doped with thallium for gamma rays. Through this information, that author can comprehend the pathways that radiation energy to luminescence takes in scintillators. This information is important if one is to draw a comparison between scintillation yields from various scintillators. As such, this article adduces that the use of quantities that are related to scintillation efficiency is appropriate in understanding these pathways. ...

Pink Pork

Most top chefs and some scientists breathed a sigh of relief when the U.S. Department of Agriculture (USDA) announced that pink pork is safe for human consumption. For years, they have been urging the USDA body to declare that pink pork is safe in vain (Cevallos, 2011).
Previously people have viewed the pink color of pork with skepticism for they associated it with undercooking. With the recent announcement, the lovers of this rare meat do not have to worry about the pink color anymore. The color issues came about when USDA lowered the safe temperatures of cooking pork. Initially ...
