# Lam Tei Reservoir

Lam Tei Reservoir (also known as Lo Fu Hang Reservoir or Lam Tei Irrigation Reservoir) is a funnel-shaped reservoir located at the back hill of Lingnan University in Fu Tei, Tuen Mun, Hong Kong with an area of 17,000 m$^2$ and a water storage capacity of 116,000 m$^3$. It is located at the western edge of Tai Lam Country Park and less than one kilometre away from Hung Shui Hang Reservoir. Like Hung Shui Hang Reservoir, it is part of Tai Lam Chung Reservoir's further water supply plan and an irrigation reservoir. The water from the reservoir eventually flows through the Tuen Mun River and empties into the Castle Peak Bay. The reservoir can be accessed by Stage 2 of the Tuen Mun Trail.

## History

Lam Tei Reservoir was opened on 28 March 1957 by Sir Alexander Grantham, and the opening plaque can still be seen next to the reservoir.
In the past 20 years, at least six children playing in the water died in Lam Tei Reservoir. Villagers called the reservoir as "Ghost Reservoir". It is rumoured that there are "carp spirits" in the reservoir, and the children were dragged into the water to drown.

# Tragocephala viridipes

Tragocephala viridipes is a species of beetle in the family Cerambycidae. It was described by Stephan von Breuning in 1947.
# Tragodesmoceras

Tragodesmoceras is a large moderately involute ammonite with deeply embracing whorls that are higher than wide, a steep sided umbilicus and a narrowly rounded venter. Ornament consists of primary ribs that begin at the umbilical shoulder and smaller secondary ribs that begin mid flank. Ribs are sigmodal, periodically thickened and bent forward on the outer flank to cross the venter as chevrons. The suture has a broad trifid lateral lobe.
Species include Tregodesmoceras clypealoides (type), known from western Europe and the U.S., Tragodesmosderas bassi, known from Arizona and Kansas, and Tragodesoceras socorroense known from Arizona and New Mexico.
The related Muniericeras is more evolute in form, but otherwise similar.
# Lake Manassas

Lake Manassas is a 770-acre (310 ha) reservoir located in Prince William County, Virginia, to the southwest of Gainesville. It is owned and operated by the city of Manassas, Virginia, although it is located outside the city limits. The reservoir was created in the late 1960s to provide drinking water for area residents and became operational in 1970. Today it contributes to a regional water system which serves the cities of Manassas and Manassas Park, Virginia, and unincorporated areas of Prince William County. Several golf clubs have courses along the banks, including Stonewall Golf Club and Robert Trent Jones Golf Club.

## Public closure

Beginning in the 1980s, and continuing until 1995, public access to the lake was possible via a private marina. In 1999 the marina operator and the City of Manassas did not reach a mutually acceptable contract extension and the marina was closed. Since then, there has been no public boating access to Lake Manassas. In 2004, citing concerns over terrorism and the possibility of contamination by Zebra Mussels, the Manassas City Council passed an ordinance making it illegal to operate a boat on Lake Manassas. Periodic attempts have been made by the city, county, and various others to reopen the lake for public use; however, as of April 2012, none have been successful.

## Lawsuit

In 2010, developers building a subdivision partially bordering Lake Manassas offered to donate 25 acres of their land to the City of Manassas to be used as a marina. In June 2010, officials from the Virginia Department of Game and Inland Fisheries and George Mason University's Freedom Aquatic & Fitness Center presented a plan to use the donated land as a marina, however the City Council never acted to accept or reject the proposal, citing continued concerns over operating costs and how the marina would be managed to ensure the protection of the drinking water supply. The developer filed a lawsuit to force the city to grant access to the residents, but postponed court action until the issue could be negotiated outside court. When the city failed to act on the 2010 proposal, the developer returned to court, and in February, 2011, a Prince William Circuit Court ruling cleared the way for the lawsuit, though a trial date was not set.
The lake is cited as a top bass and crappie fishery in the region. It was regularly stocked with fish prior to its closure to the public.

# Lake Miike

Lake Miike (御池, Miike) is a lake in Miyakonojō and Takaharu in Miyazaki Prefecture, Japan.

## Geography and geology

The height above sea level is 305 m, the depth 93.5 meters, the deepest in Japan as the crater lake. There is no outflow of water from the lake. The lake is encircled by forests, and there is a park called Miike Yacho(Birds) no Mori and a camp site. Waterfowls such as mandarin ducks, teals, spectakled teals are seen. The lake was created by a crater resulting from a magma vapor eruption about 4200 years ago. Flatstones are seen in the layers of ground near by, called Miike floatstones or Miike bora.

## History

Along the border of the lake, there was mythologically 7 ports, and Emperor Jinmu was said to play in the neighborhood of one of the ports, Oojikou.

# White-cheeked spider monkey

The white-cheeked spider monkey (Ateles marginatus) is a species of spider monkey, a type of New World monkey, endemic to Brazil. It moves around the forest canopy in small family groups of two to four, part of larger groups of a few dozen animals. This monkey feeds on leaves, flowers, fruits, bark, honey and small insects, and it is an important means of seed dispersal for forest trees. Females give birth after a 230-day gestation period. The population of this monkey is decreasing as its forest habitat is lost to soybean production, deforestation and road construction. It is also regarded as a delicacy and hunted for food. For these reasons, the International Union for Conservation of Nature has assessed the animal's conservation status as being "endangered".

## Distribution

The white-cheeked spider monkey is commonly found in the Brazilian Amazon. The area in which it is most likely to be found is between the Rio Tapajós (right bank) and its tributary, the Rio Teles Pires/Sao Manuel (right bank) and the Rio Xingu (left bank), south of the Amazonas River. A portion of their territory lies also within national forests such as Tapajós National Forest (545,000 ha (1,350,000 acres)), Xingu National Forest (252,790 ha (624,700 acres)), Altamira National Forest (689,012 ha (1,702,590 acres)), Itaituba I National Forest (220,034 ha (543,720 acres)), and Itaituba II National Forest (440,500 ha (1,088,000 acres)).

## Ecology

It is common for the white-cheeked spider monkey to travel in smaller groups of 2-4 when feeding and resting. At around 4–5 years of age, it apparently reaches sexual maturity and will give birth to one offspring after a gestation period of 226–232 days; the interbirth interval can last as long as 28–30 months in the wild.
The diet of the white-cheeked spider monkey consists of fruit, leaves, flowers, aerial roots, bark, decaying wood, honey, and even some small insects such as termites and caterpillars. One very important impact it has on its habitat is to provide seed dispersal for different species of plants throughout their territory. It is thought that they provide movement for up to 138 different species of fruit seeds.

## Status

There are many different colors of spider monkeys, such as black, brown, and white. Their homes are in the upper levels of the rain forest. The white-cheeked spider monkey was placed on the endangered species list after an assessment in 2008 discovered that their population had decreased by 50% over the course of three generations; this decline can be attributed to habitat loss and hunting. This trend is expected to continue due to the increasing expansion of soybean agriculture. Also, parts of their habitat have been destroyed to make way for major highways and extensive deforestation.
Some of the indigenous peoples in Brazil consider spider monkeys a delicacy, and when this is combined with their low reproduction rate, the population is sure to decline swiftly. It generally lives in groups of 20-30 individuals, but it is rare for them to be seen all together.

Its main base was in Bonaire, with focus cities in Aruba and Curaçao. It was merged into Dutch Antilles Express in 2005.

## History

The airline was established in 2003 and started operations on 18 August 2003. It was formerly known as BonairExel and was wholly owned by Bonair Bellegings Participatie Maatschappij. BonairExel formed part of the ExelAviation Group as the initial feeder between the islands of the Netherlands Antilles. On 30 April 2005 BonairExel was merged with Curaçao Express and both companies assets and personnel where transferred which together formed Dutch Antilles Express.
Initially, regarding aircraft, those flying under the BonairExel brand were used interisland between Aruba, Bonaire and Curaçao. The one under CuraçaoExel was used on the Bonaire-Curaçao-Sint Maarten route and the one under ArubaExel was planned to be used on the Aruba-Venezuela routes connecting to and from Bonaire/Curaçao but never commenced due to the dismantling of the ExelAviation Group. The Embraer 145 was planned to be used to fly to the United States but was considered too small in size and baggage space.

# Bomb Alarm System

The Bomb Alarm System (also known as the Bomb Alarm Display System) was a US and UK network of optical bhangmeter sensors intended to confirm the detonation of an enemy nuclear weapon near cities or military installations within the US or at US operated early warning radar sites in the UK or Greenland.
The BAS was designed by Western Union in 1959 and was in full operation by 1962. The BAS was the responsibility of the 9th Space Division. The BAS operated until 1967.
The BAS sensors were designed to report the occurrence of a nuclear flash via telephone or telegraph lines before the sensor was destroyed by the explosion. They were designed to ignore spurious signals from lightning, sunlight, or electrical surges.
