Earth auger. An earth auger, earth drill, or post-hole auger is a drilling tool used for making holes in the ground. It typically consists of a rotating vertical metal rod or pipe with one or more blades attached at the lower end, that cut or scrape the soil.

History

Metal augers have been in use since the Middle Ages to drill holes in wood.  In the 19th century, the hand-operated earth auger became a common farm and construction tool in the US, and several inventors submitted patents for them. An example is the design of a certain M. Hubby of Maysfield, Texas, consisting of an open hollow cylinder with two blades at the bottom edge. 

The first known power earth auger was built in 1943 by John Habluetzel, a farmer in Wamego, Kansas, from parts scavenged from other equipment, including a 7-inch helical blade from a screw  separator. It was attached to a tractor and could be operated by the driver from his seat.  It dug one 2.5 foot deep hole every minute.   His invention was featured in the Kansas State Board of Agriculture's 35th Biennial Report.  He went on to dig holes for other farmers at 10 cents per hole, a side business that he operated well into the 1950s.  He donated his invention to the Kansas Museum of History in 1999.

Types

Blade arrangement
The most common design of earth auger has a helical screw blade (the flighting) winding around lower part of the shaft.  The lower edge of the screw blade scrapes dirt at the bottom of the hole, and the rest of the blade acts like a screw conveyor to lift the loose soil out of the way.  When the hole reaches the desired depth and the tool is pulled out, the screw blade scoops out the remaining loose dirt.

The rod may end in a sharp point protruding below the screw  blade.  Its purpose is to push the dirt that lies just below the rod to the sides, where the blade can pick it up.  It also helps keep the hole straight by prevent the auger from wandering off to the side.  The lower edge of the screw blade may have teeth.

Another type of earth auger has two vertical blades instead of a helical screw.  Rather than scraping the soil at the bottom of the hole, this type of auger cuts a cylindrical plug out of it, that is held by friction between the two blades.  The auger must then be pulled out and emptied every foot or so.  This type may require less force to operate, but may be adequate only for certain types of soil.

Power source
An earth auger can be powered by hand, through a T-shaped horizontal handle at the top of the rod.

An earth auger can also be powered by an electric motor or internal-combustion engine, or from a tractor or other vehicle through a power take-off.

Uses

Hand-powered earth augers are typically used to plant saplings and trees or to set up posts for fences or other ends.

Large mechanized earth augers, called drilling rigs, are used to make holes for piles destined to be deep foundations or retaining wall.

Gas- or hand-powered augers are used by ice fishermen to drill through the ice layer over lakes or rivers.

Toyota FC Bus. The Toyota FC Bus is a transit bus with an electric motor powered by hydrogen fuel cells produced by Toyota, developed in cooperation with Hino Motors. The bus uses components originally developed for the Toyota Mirai, a mid-size fuel cell sedan.

Hydrogen fuel cells generate electricity by reacting hydrogen and oxygen in the presence of a catalyst, the by-product of which is water. Hydrogen is stored in carbon and glass fiber tanks and oxygen is taken from the air.

The FC Bus is equipped with a power supply system for external receivers with a maximum power of 9 kW, which provides a maximum of 235 kWh of energy. Fuel cells are the source of energy. The purpose of this installation was to put an emergency power source for use in the city in the event of a natural disaster, such as an earthquake or tsunami.

The bus was replaced by the Toyota Sora in 2018.

History 
Japan's first hydrogen fuel cell bus - the Toyota FCHV-BUS - was demonstrated in the early 2000s, and was used during Expo 2005.

In July 2015, Toyota tested a prototype fuel cell bus on bus routes in Tokyo. The prototype was developed in cooperation with Hino Motors, on the basis of the Hino hybrid bus and the Toyota Mirai fuel cell system. The bus was also lent to Meitetsu Bus for free, as a demonstration that fuel cell buses were practical.

In February 2017, Toyota began selling the FC Bus. The first copy was purchased by the Tokyo Metropolitan Government's Transport Office and was included in the Tokyo city bus network in March 2017. By 2020, Toyota supplied the Tokyo authorities with more than 100 Toyota FC Bus buses. This is part of the plan to promote the automotive industry using fuel cells at the Tokyo Olympic and Paralympic Games in 2020.

Naval Decoy IDS300. Naval Decoy IDS300 (Inflatable Decoy System) is a passive, off-board, octahedral, corner reflector decoy of the Royal Navy's Type 45 destroyer and the US Navy's  destroyer, forming part of a layered defence to counter anti-ship missiles.  Unlike chaff, the decoy is persistent and will float for up to three hours in sea state 4.

Jane's was first to report the United Kingdom was looking for a new floating decoy as part of a program known as the Naval Passive Off-Board Decoy (N-POD), on March 3, 2019.  In US Navy service, it is designated as the Mk 59 decoy launching system. The system is made by Irvin Aerospace Ltd, Hertfordshire in the United Kingdom.

Deployment
The decoy is launched out of a deck-mounted tube and self-inflates on the sea surface before being released to free-float past the stern to mimic a ship's radar and radio signatures. The deployment and inflation process takes seconds and the decoy is completely independent, requiring no further input from the ship. Typical ship fitment is four launchers, fitted using eight bolts and an electrical feed. The system is most effective in littoral waters with a calm sea state.

Pyle-National Company Plant. The Pyle-National Company Plant is a historic industrial plant at 1334 North Kostner Avenue in the Humboldt Park neighborhood of Chicago, Illinois. The Pyle-National Company, which produced lights for steam locomotives and other heavy machinery, built the plant in 1916. The company was founded in 1897 by George C. Pyle, an inventor who patented several designs for locomotive headlights, and businessman Royal C. Vilas. The company's products became the first successful electric locomotive headlights, and the success of their and their competitors' lights led Congress to require electric headlights on all locomotives in 1915. Expecting increased business from the Congressional mandate, the company expanded to the Kostner plant, which had three buildings designed by the Chicago industrial architecture firm Davidson & Weiss. The plant served as Pyle-National's only production site until 1963 and was expanded several times in the intervening decades. While Pyle-National opened a new plant in South Carolina in 1963 and pivoted away from the lighting industry, it continued to use its Chicago factory until 1992.

The plant was added to the National Register of Historic Places on January 19, 2021.

Dhaka–Bhanga Expressway. The Dhaka–Bhanga Expressway is the first national expressway in Bangladesh.It is operated by the Road Transport and Highways Division. The express will be connected to Asian Highway 1.

In 2022, it was officially named after Sheikh Mujibur Rahman. After the successful student uprising in 2024, locals tore down the expressway's official nameplate and hung a banner in the name of Islamic prophet Ibrahim.

History
ECNEC approved the Dhaka-Mawa-Bhanga expressway construction under Dhaka-Khulna Highway Project on 3 May 2016. The budget for the project was Tk 11,003.90 crore, later revised to Tk 6,892 crore. However, only half of the construction was done with this allocated money. With an additional Tk 4,111.86 crore the construction was completed. RHD and Bangladesh Army were involved in the construction of the expressway.

On 19 August 2021, it was proposed that Korea Expressway Corporation should be given the task of toll management of the expressway. The proposal was made by the Cabinet Committee on Economic Affairs (CCEA).

Overview
The six-lane expressway has two service lanes for local passengers, and 19 pedestrian underpasses for crossing. It goes through five rivers via flyovers. The Padma Bridge is opened for public use, and people can use the bridge to enter the expressway.

Arvid Reuterdahl. Arvid Reuterdahl (February 15, 1876 – January 13, 1933) was a Swedish-American engineer, scientist and educator.

Biography

Reuterdahl was born at Karlstad on February 15, 1876. He moved to the United States as a child in 1882. He graduated Sc.B. from Brown University in 1897 and was a mathematics and physics instructor at the Technical High School in Providence. Reuterdahl worked as an engineer in Spokane, Washington for five years and as an assistant city engineer, water commissioner and President of the board of public works. He designed bridges for the city. He was an consulting engineer of Boise, Idaho (1910–1913) and Kansas City, Missouri (1913–1918).

He was professor of theoretical and applied mechanics at Kansas City Polytechnic Institute (1915–1918) and was the first Dean of the Department of Engineering and Architecture at the College of St. Thomas (1918–1922). He was President of the Ramsey Institute of Technology, Saint Paul, Minnesota (1922-1926).

He was a Fellow of the American Association for the Advancement of Science. He married Elinor Morrison on June 16, 1902. They had one son, Norman Morrison Reuterdahl.

Opposition to the theory of relativity

Reuterdahl was a noted opponent of Albert Einstein's theory of relativity. He considered Einstein's theory to be largely "bunk" and accused him of plagiarism. Reuterdahl argued that Einstein's theory of relativity was plagiarized from a mechanical gravitation theory of Scottish engineer Robert Stevenson (pseudonym Kinertia). He argued that Stevenson's papers were sent to the Prussian Academy of Sciences in 1903 and that Einstein, a member of the Academy secretly made use of the papers.

Reuterdahl communicated with other anti-relativists such as Ernst Gehrcke. He was science editor for Henry Ford's journal the Dearborn Independent.

Toyota Sora. The  is a transit bus with an electric motor powered by hydrogen fuel cells produced by Toyota, developed in cooperation with Hino Motors. The bus uses components originally developed for the Toyota Mirai, a mid-size fuel cell sedan. The name Sora is an abbreviation of the words Sky, Ocean, River and Air and refers to the water cycle.

Technical details 
With a capacity of 78 passengers, the Sora uses fuel cells to power the bus, in which 10 tanks carrying 600 litres of hydrogen feeds two sets of polymer electrolyte fuel cells which can produces an output of . A single refuelling takes only 10 minutes for a  journey compared to conventional battery electric buses which takes around 5 hours for the batteries to be fully charged. The bus is also equipped with an external power supply system which can be used as an emergency source of electricity, providing external consumers with up to 235 kWh of electricity with a maximum power of 9 kW.

Features 
The Sora uses an automatic stopping system. It follows lines on the road and, using automatic steering and braking, stops the bus from  from the edge of the stop, and also not more than  in front of or behind the designated stop line. The bus has an environment monitoring system based on eight cameras located inside and outside the vehicle, combined with radar and a collision warning system, to detect pedestrians and cyclists in the vicinity and alert the driver to their presence using audible and visual signals. The bus is also equipped with an acceleration control function, which protects standing passengers from too rapid acceleration.

The Sora cooperates with the ITS Connect system, which uses communication between vehicles and between vehicles and road infrastructure to improve driving safety, as well as systems supporting bus convoys and ensuring priority at traffic lights (Public Transportation Priority Systems). Toyota buses can exchange information about traffic, pedestrians or changes in lights with other vehicles. The Emergency Driving Stop System also allows passengers to stop the vehicle in an emergency, for example if the driver collapses.

Sales and export 
The Sora made its debut at the Tokyo Motor Show in 2017.  It went on sale in Japan on 7 March 2018 with more than 100 buses in the public transport fleet, mainly for Tokyo BRT, Keikyu Bus and Toei Bus, ahead of the 2020 Olympic and Paralympic Games, which took place in the Japanese capital.

In Europe, the Sora is sold as a chassis fitted with Caetano H2.City Gold bodywork supplied by Portuguese manufacturer Salvador Caetano, who have been a long-time partner for importing Toyota commercial vehicles into Europe. , numerous orders for Caetano-bodied Soras have been placed, predominantly in Germany.
