Pipeline transport is a method of transporting goods, particularly fluids such as oil, gas, water, and other substances, through a system of pipes. This mode of transport is widely used for its efficiency in moving large volumes of materials over long distances. Here are some key features and advantages of pipeline transport: 1. **Types of Fluids**: Pipelines can transport various substances, including natural gas, crude oil, refined petroleum products, chemicals, water, and even slurry mixtures.
The mode of transport refers to the various means or methods used to move people or goods from one location to another. Different modes of transport enable different speeds, costs, and efficiencies, and can be categorized into several main types: 1. **Land Transport**: This includes vehicles that travel on roads and tracks. Examples are: - **Road transport**: Cars, buses, trucks, motorcycles, bicycles. - **Rail transport**: Trains, subways, trams.
"Vehicles by period" typically refers to the classification or categorization of vehicles based on specific historical periods or eras. This classification can encompass a wide range of factors, including design styles, technological advancements, manufacturing techniques, and societal changes that influenced vehicle production and use. Here are some common periods in automotive history: 1. **Early Auto Era (Late 19th to Early 20th Century)**: - The advent of the automobile with vehicles powered by steam, electricity, and gasoline.
The Beeching closures refer to a significant reduction of the British railway network in the 1960s, resulting from recommendations made by Dr. Richard Beeching, who was the chairman of British Railways. In 1963, he published a report titled "The Reshaping of British Railways," which aimed to address the financial losses encountered by the rail sector.

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.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. 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-calculus
    Articles 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.

  2. local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:
    This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.
