🔗 Crime 🔗 Mining

Sand theft or unauthorised or illegal sand mining leads to a widely unknown global example of natural and non-renewable resource depletion problem comparable in extent to global water scarcity. Beach theft is illegal removal of large quantities of sand from a beach leading to full or partial disappearance of the beach.

The Interplanetary Transport Network (ITN) is a collection of gravitationally determined pathways through the Solar System that require very little energy for an object to follow. The ITN makes particular use of Lagrange points as locations where trajectories through space are redirected using little or no energy. These points have the peculiar property of allowing objects to orbit around them, despite lacking an object to orbit. While it would use little energy, transport along the network would take a long time.

🔗 Finance & Investment 🔗 Economics 🔗 Business 🔗 Cooperatives

A credit union, a type of financial institution similar to a commercial bank, is a member-owned nonprofit financial cooperative. Credit unions generally provide services to members similar to retail banks, including deposit accounts, provision of credit, and other financial services. In several African countries, credit unions are commonly referred to as SACCOs (Savings and Credit Co-Operatives).

Worldwide, credit union systems vary significantly in their total assets and average institution asset size, ranging from volunteer operations with a handful of members to institutions with hundreds of thousands of members and assets worth billions of US dollars. In 2018, the number of members in credit unions worldwide was 274 million, with nearly 40 million members having been added since 2016.

Leading up to the financial crisis of 2007–2008, commercial banks engaged in approximately five times more subprime lending relative to credit unions and were two and a half times more likely to fail during the crisis. American credit unions more than doubled lending to small businesses between 2008 and 2016, from $30 billion to $60 billion, while lending to small businesses overall during the same period declined by around $100 billion. In the US, public trust in credit unions stands at 60%, compared to 30% for big banks. Furthermore, small businesses are 80% less likely to be dissatisfied with a credit union than with a big bank.

"Natural-person credit unions" (also called "retail credit unions" or "consumer credit unions") serve individuals, as distinguished from "corporate credit unions", which serve other credit unions.

🔗 Spaceflight

HAL/S (High-order Assembly Language/Shuttle) is a real-time aerospace programming language compiler and cross-compiler for avionics applications used by NASA and associated agencies (JPL, etc.). It has been used in many U.S. space projects since 1973 and its most significant use was in the Space Shuttle program (approximately 85% of the Shuttle software is coded in HAL/S). It was designed by Intermetrics in 1972 for NASA and delivered in 1973. HAL/S is written in XPL, a dialect of PL/I. Although HAL/S is designed primarily for programming on-board computers, it is general enough to meet nearly all the needs in the production, verification, and support of aerospace and other real-time applications. According to documentation from 2005, it was being maintained by the HAL/S project of United Space Alliance.

Rongorongo (; Rapa Nui: [ˈɾoŋoˈɾoŋo]) is a system of glyphs discovered in the 19th century on Easter Island that appears to be writing or proto-writing. Numerous attempts at decipherment have been made, none successfully. Although some calendrical and what might prove to be genealogical information has been identified, none of these glyphs can actually be read. If rongorongo does prove to be writing and proves to be an independent invention, it would be one of very few independent inventions of writing in human history.

Two dozen wooden objects bearing rongorongo inscriptions, some heavily weathered, burned, or otherwise damaged, were collected in the late 19th century and are now scattered in museums and private collections. None remain on Easter Island. The objects are mostly tablets shaped from irregular pieces of wood, sometimes driftwood, but include a chieftain's staff, a bird-man statuette, and two reimiro ornaments. There are also a few petroglyphs which may include short rongorongo inscriptions. Oral history suggests that only a small elite was ever literate and that the tablets were sacred.

Authentic rongorongo texts are written in alternating directions, a system called reverse boustrophedon. In a third of the tablets, the lines of text are inscribed in shallow fluting carved into the wood. The glyphs themselves are outlines of human, animal, plant, artifact and geometric forms. Many of the human and animal figures, such as glyphs 200 and 280 , have characteristic protuberances on each side of the head, possibly representing eyes.

Individual texts are conventionally known by a single uppercase letter and a name, such as Tablet C, the Mamari Tablet. The somewhat variable names may be descriptive or indicate where the object is kept, as in the Oar, the Snuffbox, the Small Santiago Tablet, and the Santiago Staff.

Euro English or European English, less commonly known as EU English and EU Speak, is a pidgin dialect of English based on the technical jargon of the European Union and the native languages of its non-native English speaking population. It is mostly used among EU staff, expatriates from EU countries, young international travellers (such as exchange students in the EU’s Erasmus programme), European diplomats, and sometimes by other Europeans that use English as a second or foreign language (especially Continental Europeans).

The term 3-6-3 Rule describes how the United States retail banking industry operated from the 1950s to the 1980s. The name 3-6-3 refers to the impression that bankers had a stable, comfortable existence by paying 3 percent interest on deposits, lending money out at 6 percent, and being able to "tee off at the golf course by 3 p.m."

The implication was that the banks were less competitive during that period than in subsequent years due to tight regulations that limited the formation and location of banks as well as restrictions on interest rates that could be charged or paid. As a result, bankers had "power and prestige ... while profits were steady and certain". These regulations were loosened in the 1980s.

Richmond Federal Reserve senior economist John R. Walter argues that, although there is evidence that restrictions on banks before the 1980s did limit the competitiveness of banking markets and thereby granted some banks monopoly power, "the regulatory restrictions probably had a limited effect on competition" during the time in question. Chicago Federal Reserve researchers Robert DeYoung and Tara Rice argue that, "Like most good jokes, the 3-6-3 rule mixes a grain of truth with a highly simplified view of reality."

The rule has been noted positively following the late-2000s financial crisis as a preferable way for banks to operate following the bailout of major banks.

Australia's banking system, which was deregulated in the 1990s in a manner similar to that in the U.S., also came to be characterized in the same way as did the United Kingdom's.

William of Rubruck (Dutch: Willem van Rubroeck, Latin: Gulielmus de Rubruquis; fl. 1248–1255) was a Flemish Franciscan missionary and explorer.

He is best known for his travels to various parts of the Middle East and Central Asia in the 13th century, including the Mongol Empire. His account of his travels is one of the masterpieces of medieval travel literature, comparable to those of Marco Polo and Ibn Battuta.

🔗 Technology 🔗 Trains

An atmospheric railway uses differential air pressure to provide power for propulsion of a railway vehicle. A static power source can transmit motive power to the vehicle in this way, avoiding the necessity of carrying mobile power generating equipment. The air pressure, or partial vacuum (i.e., negative relative pressure) can be conveyed to the vehicle in a continuous pipe, where the vehicle carries a piston running in the tube. Some form of re-sealable slot is required to enable the piston to be attached to the vehicle. Alternatively the entire vehicle may act as the piston in a large tube.

Several variants of the principle were proposed in the early 19th century, and a number of practical forms were implemented, but all were overcome by unforeseen disadvantages and discontinued within a few years.

A modern proprietary system has been developed and is in use for short-distance applications. Porto Alegre Metro airport connection is one of them.
