On2 gauge is a narrow gauge model railroad scale that represents a prototype gauge of 2 feet (610 mm). In this scale, the models are typically built to a ratio of 1:48, which means that 1 inch on the model equates to 4 feet on the actual train. On2 gauge models are primarily used to simulate narrow gauge railroads, which were often found in mountainous regions or places where terrain made construction of standard gauge railroads impractical.

"Onnenpyörä" is Finnish for "Wheel of Fortune." It refers to a popular game show format where a large wheel is spun to determine prizes or cash amounts for contestants. The show involves participants answering questions or solving puzzles, often in a manner similar to the American version, also named "Wheel of Fortune." The Finnish version has been well-received and is part of the country's entertainment culture.

"On the Luna" could refer to various things, but without additional context, it is unclear what you specifically mean. It could be a reference to a place, a book, a song, or even a brand.

Openswan is an open-source implementation of the IPsec (Internet Protocol Security) protocol suite, primarily used for creating secure VPN (Virtual Private Network) connections. It facilitates the establishment of encrypted tunnels between computers over the internet, enabling secure communication and data exchange. Key features of Openswan include: 1. **IPsec Support**: Implements both transport and tunnel modes of IPsec, allowing for varied deployment scenarios.

The optical axis is an important concept in optics, referring to an imaginary line that describes the path along which light travels through an optical system, such as a lens, mirror, or optical instrument. It is typically defined as the line that passes through the center of an optical element and is perpendicular to the surface of that element.

Optical Coherence Elastography (OCE) is an advanced imaging technique that combines principles of optical coherence tomography (OCT) with elastography to assess the mechanical properties of biological tissues. This technology is particularly useful in the field of medical diagnostics as it provides both structural and functional information about tissues. ### Key Features of Optical Coherence Elastography: 1. **Imaging Technique**: OCE utilizes light to derive images of tissue microstructures at very high resolutions.

Optical transfection is a technique used to introduce nucleic acids, such as DNA or RNA, into living cells using light-based methods. This approach leverages optical tools, such as lasers or light-emitting diodes (LEDs), to facilitate the uptake of genetic material by the cells without the need for chemical or electrical means typically used in traditional transfection methods.

As of my last update, I don't have real-time statistics or a detailed list of all-time statistical leaders for the Oral Roberts Golden Eagles men's basketball team. However, the statistical leaders often include categories such as points, rebounds, assists, steals, and blocks. For the most accurate and updated information on the Oral Roberts Golden Eagles men's basketball statistical leaders, I recommend checking the official Oral Roberts University athletics website or reviewing recent sports databases. They usually maintain comprehensive records for player statistics, including historical data.

The 18th century was a significant period for the development of physics and science in general in Italy, which was home to several notable physicists and scientists. Here are some prominent figures and contributions from Italian physicists during this period: 1. **Giovanni Battista Beccaria (1716-1781)**: An Italian physicist and a member of the Academy of Sciences in Turin, Beccaria is known for his work in the fields of electricity and heat.

František Koláček could refer to a specific individual, but without additional context, it's difficult to provide detailed information. Notably, if you are referring to a figure in history, politics, arts, or any other field, please provide more details or clarify the context you are interested in. If there's a particular focus (e.g., a work, legacy, etc.), that would help refine the information.

The conjugacy problem is a well-studied question in the field of group theory, a branch of abstract algebra. Specifically, it pertains to determining whether two elements in a group are conjugate to each other.

The 19th century was a pivotal time for scientific development in Greece, as it was a period marked by the country's struggle for independence and subsequent efforts to modernize its educational and scientific institutions. Notably, there were a few Greek physicists and scientists during this period whose contributions helped lay the groundwork for future advancements in physics and related fields.

The 19th century was a period of significant advances in physics in France, led by several prominent physicists whose contributions helped to shape modern science. Here are a few notable French physicists from that era and their key contributions: 1. **Auguste Comte (1798-1857)**: While primarily known as a philosopher and the founder of positivism, Comte’s ideas influenced the development of sociology and the scientific approach in social sciences, which intersected tangentially with physics.

The 1960s was a significant decade in the history of computing, marked by several key developments that shaped the evolution of computer technology and laid the groundwork for future advancements. Here are some highlights from that era: 1. **Mainframe Computers**: The 1960s saw the dominance of large mainframe computers.

De Sitter invariant special relativity refers to a theoretical framework that extends the principles of special relativity to include de Sitter space, which is a model of spacetime that includes a positive cosmological constant. This framework can be seen as an extension of the usual flat Minkowski spacetime of special relativity, incorporating the geometric properties associated with de Sitter space, which has a constant positive curvature.

The term "Soviet physicists" refers to scientists who specialized in the field of physics and worked in the Soviet Union from its establishment in 1922 until its dissolution in 1991. During this period, the Soviet Union was home to many influential physicists who made significant contributions to various areas of physics, including theoretical and experimental physics, astrophysics, condensed matter physics, and nuclear physics.
