Created by the Nuclear Waste Policy Act Amendments of 1987, the office was responsible for negotiating agreements with states or Indian tribes that would host nuclear waste facilities.
Naturally occurring radioactive material (NORM) refers to materials found in the environment that contain radioactive elements, which are naturally occurring isotopes that emit radiation as they decay over time. These materials can be found in the earth's crust, in minerals, and in various natural sources, including soil, rock, and water.
Saltcrete is a specialized type of concrete that incorporates salt (sodium chloride) into its mix. The concept of Saltcrete is often used in specific applications where the environmental conditions necessitate the use of materials that can withstand corrosive elements, particularly in coastal areas or in applications involving road salt. The inclusion of salt can influence various properties of the concrete, such as workability, setting times, and durability.
As of my last knowledge update in October 2023, there is no widely recognized individual, organization, or concept known as "Kaisha Atakhanova." It is possible that this name could refer to a private individual, a newly emerging public figure, or a specific term relevant in a particular context or regional area that has not gained global recognition.
Paul Bonét-Maury was a notable French geologist and paleontologist, renowned for his contributions to the field of stratigraphy and his work in the study of fossilized organisms. His research particularly focused on the stratigraphic characteristics of sedimentary rocks and the paleoenvironmental conditions of various geological formations. His work has had a lasting impact on the understanding of Earth's geological history and the processes that have shaped it over millions of years.
The Fajans–Paneth–Hahn Law is a principle in the field of chemistry that relates to the behavior of certain chemical reactions, particularly in the context of ion formation and solubility. This law describes the tendency of certain ions (especially cations) to favor one of two solubility product equilibria based on their charge density, which is influenced by their charge and size.
Satoyasu Iimori is a unique term that refers to a type of traditional Japanese architecture, specifically related to rural farmhouses. The term "Satoyasu" can signify a style that incorporates elements of the surrounding natural environment, showcasing harmony between human dwellings and nature. "Iimori" is associated with the architectural features of these farmhouses, particularly the use of natural materials and techniques that emphasize sustainability and traditional craftsmanship.
Neuroradiology is a specialized branch of radiology that focuses on the diagnosis and treatment of conditions affecting the nervous system, including the brain, spine, head, and neck. It involves the use of various imaging techniques to visualize the anatomy and pathology of these areas.
Digital X-ray radiogrammetry (DXR) is a sophisticated imaging technique used primarily in the evaluation of bone quality and structure through analysis of X-ray images. It involves using digital X-ray technology to capture high-resolution images of skeletal structures, allowing for detailed assessment of bone mineral density and geometry. ### Key Features of DXR: 1. **Digital Imaging**: DXR utilizes digital X-ray systems rather than traditional film-based radiography.
EOS in the context of medical imaging refers to a specific imaging system designed for skeletal imaging, particularly for the assessment of the spine and pelvis. The EOS imaging system is known for its low-dose X-ray technology, which allows for high-quality, 2D and 3D imaging of the skeletal structure while minimizing radiation exposure to patients.
The International Day of Radiology (IDoR) is celebrated annually on November 8th. It was established to promote the role of radiology in modern healthcare and to raise awareness of the importance of medical imaging in patient diagnosis and treatment. The day also serves to highlight the contributions of radiologists and radiologic technologists to patient care and to foster collaboration among healthcare professionals.
The John Thomas sign is a term used in medical imaging to describe a specific finding in radiographs (X-rays) of the pelvis associated with certain types of fractures. It is most notably linked to fractures of the femoral neck, particularly in older adults. Specifically, it refers to the presence of a horizontal line that appears across the upper part of the femoral neck on X-ray images.
Radiodensity refers to the ability of a material to absorb or transmit radiation, particularly X-rays or gamma rays. It is a measure of how dense a substance is in terms of its interaction with electromagnetic radiation. In medical imaging, such as radiography, different tissues and materials within the body have varying radiodensities, which allows for the creation of images.
Schuller's view, also known as the Schuller view, refers to a specific radiographic projection used in dentistry and oral surgery, particularly for imaging the maxillary sinus and the position of the maxillary teeth. It is achieved by tilting the patient's head backward and centering the X-ray beam to capture a view that allows for visualization of the maxillary sinus, the nasal cavity, and surrounding structures.
Surgical planning is a crucial step in the surgical process that involves detailed preparation and strategizing for a surgical procedure. It encompasses a variety of components to ensure that the surgery is performed safely, effectively, and with optimal outcomes for the patient. Key elements of surgical planning include: 1. **Preoperative Assessment**: Evaluating the patient's medical history, physical condition, and any comorbidities that could affect the surgery.
Cosmogenic nuclides are isotopes that are formed by the interaction of cosmic rays with atomic nuclei in the Earth's atmosphere or the surface of the Earth. Cosmic rays, which are high-energy particles originating from space, collide with atoms in the atmosphere or on the surface, resulting in nuclear reactions that produce these isotopes.
Fission track dating is a radiometric dating technique used to determine the age of geological materials, particularly minerals such as zircon, apatite, and mica. The method is based on the natural occurrence of fission tracks, which are microscopic damage trails produced in crystalline materials when uranium-238 (U-238) nuclei undergo spontaneous fission.
Rubidium-strontium (Rb-Sr) dating is a radiometric dating technique that is used to determine the age of rocks and minerals by measuring the decay of rubidium-87 (Rb-87) to strontium-87 (Sr-87). This method relies on the principles of radioactive decay, where a parent isotope (in this case, Rb-87) decays into a stable daughter isotope (Sr-87) over time at a known rate.
British Railway Modelling is a hobby that involves creating scale models of British railways, trains, and related infrastructure. Enthusiasts often build dioramas or railway layouts that replicate real or fictional scenes from Britain's railway history. This hobby combines elements of design, engineering, and artistry, as modellers work on constructing realistic landscapes, buildings, and train systems.
Model railroading is a popular hobby that involves the creation and operation of miniature train layouts. Enthusiasts build and operate scale models of trains, tracks, and landscapes, often setting up intricate scenes that can include everything from realistic terrain and buildings to figures and vehicles. Here are some key aspects of this hobby: 1. **Scale Models**: Model railroads are built to specific scales, which determine the size of the models in relation to real trains.
Pinned article: Introduction to the OurBigBook Project
Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.

Intro to OurBigBook
. Source. We have two killer features:
- topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculusArticles of different users are sorted by upvote within each article page. This feature is a bit like:
- a Wikipedia where each user can have their own version of each article
- a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.Figure 1. Screenshot of the "Derivative" topic page.
