Vertical transport devices are equipment or systems designed to move people or goods vertically between different levels or floors of a building or structure. These devices play a crucial role in architecture and building design, enhancing accessibility and efficiency. Common types of vertical transport devices include: 1. **Elevators**: Enclosed platforms or cabins that move up and down within a shaft to transport passengers or cargo between floors.
Cycling infrastructure refers to the built environment and facilities designed specifically to accommodate and promote cycling as a mode of transportation. This infrastructure contributes to safer, more efficient, and more convenient cycling for all users. Key components of cycling infrastructure include: 1. **Bike Lanes**: Designated lanes on roadways that separate cyclists from motor vehicle traffic. These can be painted lanes, protected lanes with physical barriers, or multi-use paths.
A "roadhouse" typically refers to a type of establishment that combines a bar, restaurant, and often a venue for live music or entertainment, situated along a road, particularly in rural or semi-rural areas. The concept originated in the United States and is often associated with casual dining, hearty food, and a laid-back atmosphere.
Bridge law typically refers to a set of legal principles and regulations governing the construction and maintenance of bridges, as well as the responsibilities and liabilities associated with them. This can include aspects of civil law, tort law, and administrative law, depending on the jurisdiction. In a more specific context, "bridge law" might also refer to laws related to the financial sector, particularly those governing bridge financing or temporary funding solutions for projects, which might not be the primary focus of traditional lending practices.
Roadworthiness refers to the condition of a vehicle being safe and compliant with regulations to be driven on public roads. A roadworthy vehicle should meet specific safety standards and be in good mechanical condition, ensuring it can operate safely under normal driving conditions. Key aspects of roadworthiness typically include: 1. **Brake System**: The braking system must be effective, ensuring the vehicle can stop safely. 2. **Tires**: Tires should have adequate tread depth, proper inflation, and be free from defects.
"Incomplete transport lists" generally refers to situations where a designated list of items or components that need to be transported is missing certain elements. This concept can arise in various contexts, including logistics, supply chain management, and transportation. Here are a few possible interpretations and implications: 1. **Logistics and Shipping**: In the context of shipping goods, an incomplete transport list might mean that not all items scheduled for shipment are listed.
Rail transport organizations are entities that manage, operate, or support the railway industry, which includes the infrastructure, rolling stock (trains and carriages), and services related to rail transport. These organizations can be public or private and may operate at various levels, including local, regional, national, or international. They play a crucial role in the planning, development, regulation, and operation of rail networks.
A list of trolleybus systems includes cities and regions around the world that use trolleybuses as part of their public transportation network. Trolleybuses are electric buses that draw power from dual overhead wires, allowing them to operate in a similar manner to trams or streetcars while maintaining the flexibility of buses. Here are some notable trolleybus systems: ### North America - **San Francisco, California** - Known for its iconic trolleybuses and extensive system.
Electromigration is a physical phenomenon that occurs in conductive materials, particularly in metals used in microelectronic devices. It refers to the transport of metal atoms within a conductor due to the movement of electrical current. When a high current density passes through a metal interconnect (such as copper or aluminum), it can cause metal ions to migrate from areas of high density to areas of low density, leading to voids (or gaps) in the material.
Reactive transport modeling in porous media is a multidisciplinary approach used to simulate the movement of fluids and solutes through porous materials, while accounting for the chemical reactions that occur within those materials. This type of modeling is essential for understanding processes in various natural and engineered systems, such as groundwater flow, contaminant transport, soil science, chemical engineering, and environmental remediation. ### Key Components of Reactive Transport Modeling: 1. **Porous Media**: Refers to the material through which fluids are moving.
An antiporter is a type of membrane transport protein that facilitates the movement of two different ions or molecules across a cell membrane in opposite directions. This process is crucial for various physiological functions, including maintaining ion balance, regulating pH, and transporting nutrients or waste products. In an antiporter, one molecule is typically transported into the cell while another is transported out. This exchange often occurs simultaneously and relies on the concentration gradient of one or both substances.
Chemotaxis is the movement of an organism or a cell in response to a chemical gradient. This biological phenomenon typically involves the movement towards higher concentrations of beneficial substances (such as nutrients) or away from harmful substances (such as toxins). Chemotaxis is observed in various organisms, including bacteria, single-celled organisms, and multicellular organisms, and is crucial for processes such as immune response, wound healing, and the navigation of cells to specific sites in tissues.
Heat transfer through fins refers to the process by which excess heat is dissipated from a surface to the surrounding environment through extended surfaces known as fins. Fins are typically used in applications where heat needs to be removed efficiently from a solid object, such as in heat exchangers, electronic components, radiators, and engines. ### Key Concepts: 1. **Purpose of Fins**: Fins increase the surface area available for heat transfer.
The groundwater flow equation is a fundamental equation used in hydrogeology to describe the movement of groundwater through the subsurface. The most commonly used form of the equation is derived from Darcy's Law and the principle of conservation of mass.
Contour advection refers to the process of transporting a scalar field (like temperature, pressure, or concentration) along the contours (or level curves) of that field, often in the context of fluid dynamics and atmospheric sciences. This concept is useful when dealing with the movement of scalar quantities in a flowing medium, where these quantities are embedded within a velocity field.
Molecular Tagging Velocimetry (MTV) is an advanced optical measurement technique used to visualize and quantify fluid flow and velocities in various scientific and engineering applications. This method is particularly useful in fluid dynamics research and is often employed in experiments involving turbulent flows, sprays, and other complex fluid behaviors. ### Key Features of Molecular Tagging Velocimetry: 1. **Fluorescent Tagging**: In MTV, specific molecules (tags) are introduced into the fluid.
The Coupled Model Intercomparison Project (CMIP) is a coordinated, international effort that aims to improve the understanding of climate change and its impacts by facilitating the comparison of coupled climate models. It brings together climate models from various research institutions around the world, enabling them to work on a common set of experiments and scenarios. CMIP serves several important purposes: 1. **Standardization**: By providing a standardized framework for climate modeling, CMIP allows researchers to compare different climate models more effectively.
ECMWF reanalysis refers to a comprehensive set of climate data produced by the European Centre for Medium-Range Weather Forecasts (ECMWF) that provides a historical record of the atmosphere, oceans, and land surface. The most notable reanalysis project by ECMWF is the ERA (ECMWF Re-Analysis) series, which includes several versions like ERA-Interim and ERA5.

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.
