Holism is a philosophical and conceptual approach that emphasizes the importance of understanding systems and phenomena as a whole rather than merely as a collection of parts. The term comes from the Greek word "holos," meaning "whole" or "entire." Holism suggests that the properties and behaviors of a system cannot be fully understood by examining its individual components in isolation; instead, the interactions and relationships between those components contribute significantly to the system's overall functionality and characteristics.
Mean Glandular Dose (MGD) is a calculated value that represents the average radiation dose received by the glandular tissue of the breast during mammography. It is an important metric in radiology, particularly in breast imaging, as it helps to assess and monitor the potential risks of radiation exposure associated with mammography procedures. The MGD takes into account various factors, including: 1. **Radiation Exposure**: The amount of x-ray radiation used during the mammographic procedure.
Climatologists are scientists who study climate, which is the long-term pattern and average of weather conditions in a specific area over extended periods, typically decades to millions of years. Their work encompasses understanding the Earth's climate systems, including factors that influence climate such as atmospheric conditions, ocean currents, solar radiation, and human activities. Climatologists analyze various data, including temperature records, precipitation patterns, and atmospheric composition, to identify trends and make predictions about future climate changes.
A passive dual coil resonator is a type of resonant circuit that comprises two inductive coils (or inductors) arranged in a specific configuration to create resonance at a particular frequency. These circuits are commonly used in various applications involving resonance, such as in radio frequency (RF) systems, wireless power transfer, and electromagnetic field sensing.

Established in the 1990s, the RPHP aims to investigate the potential health risks associated with radiation exposure, especially in communities residing near nuclear facilities.
Technetium-99m (Tc-99m) generator, also known as a "molybdenum/technetium generator", is a device used in nuclear medicine to produce the radiopharmaceutical technetium-99m. Tc-99m is the most commonly used radioactive isotope for diagnostic imaging due to its ideal physical properties, such as a relatively short half-life of about 6 hours and its ability to emit gamma rays that can be easily detected by imaging equipment.
The term "Ultrasound Research Interface" typically refers to a platform or framework that facilitates the research and development of ultrasound technology. This can involve a variety of components, including hardware, software, and protocols designed for the acquisition, processing, and analysis of ultrasound data. Researchers and developers use such interfaces to investigate new applications, improve existing techniques, and enhance the performance of ultrasound systems in fields like medical imaging, non-destructive testing, and industrial applications.
Wireless device radiation refers to the electromagnetic radiation emitted by various wireless devices, such as cell phones, tablets, laptops, and other gadgets that communicate wirelessly over technologies like Wi-Fi, Bluetooth, and cellular networks. This type of radiation is typically non-ionizing, meaning it does not have enough energy to remove tightly bound electrons from atoms or molecules, which could lead to cellular damage or mutations like ionizing radiation (e.g., X-rays) can.
The National Fund for Scientific Research (FNRS) is a public research funding organization in Belgium, specifically in the Walloon region. It supports various scientific research initiatives across different disciplines, including natural sciences, engineering, social sciences, and humanities. Its main objectives are to promote high-quality research, facilitate collaboration among researchers, and support innovation. The FNRS provides funding through grants, fellowships, and project financing to individual researchers, research teams, and institutions.
Abacus School typically refers to educational institutions that focus on teaching mathematics using the abacus, a traditional calculating tool. These schools often emphasize mental arithmetic and cognitive development through the use of the abacus, helping students improve their calculation speed and accuracy. In some regions, especially in Asia, Abacus schools are popular and may offer programs for children as young as three years old. The curriculum often includes lessons on basic arithmetic operations, number sense, and cognitive skills that contribute to overall mathematical understanding.
Jordanus de Nemore, often referred to as Jordanus of Nemore, was a medieval mathematician and logician active in the 13th century. He is best known for his work in the fields of mathematics, especially geometry and combinatorics.
Mercury, the closest planet to the Sun, has a surface marked by craters due to its lack of atmosphere, which means that impacts from meteoroids and comets over billions of years have been well-preserved. Here is a list of some notable craters on Mercury: 1. **Caloris Basin** - One of the largest impact basins in the solar system, approximately 1,550 km (960 mi) in diameter.
Mereological nihilism is a philosophical position in the domain of metaphysics that asserts that there are no composite objects—that is, all objects are fundamental and there are no objects that are made up of parts. In essence, mereological nihilists argue that only simples or "simple objects" exist, where a simple object is something that does not have parts and cannot be divided further.
Meteorological diagrams are graphical representations that illustrate various atmospheric conditions and weather phenomena. These diagrams are essential tools in meteorology for conveying complex weather data in an easily understandable format. They can serve several purposes, from analyzing current weather conditions to predicting future weather events. Here are some common types of meteorological diagrams: 1. **Weather Maps**: These maps show the distribution of pressure systems (highs and lows), fronts, and precipitation over a specific area at a given time.
The Landauer formula is a key result in the field of quantum transport and statistical mechanics, particularly in the study of electronic transport in mesoscopic systems. It relates the conductance or current through a quantum system to its transmission properties. The formula is named after Rolf Landauer, who introduced it in the 1950s to describe how information loss in a system is related to energy dissipation in electronic circuits.
Atmospheric circulation refers to the large-scale movement of air in the Earth's atmosphere, which is driven by differences in solar heating and the rotation of the Earth. This circulation is fundamental to weather patterns and climate systems around the globe.
