The following is a list of rulers of Wallachia, from when there were first rulers until near the present:
Eugène Joseph Delporte
Eugène Joseph Delporte (January 10, 1882 in Genappe – October 19, 1955 in Uccle / Ukkel) was a Belgian astronomer. He is known for discovering 66 asteroids.
Some of his notable discoveries are 1221 Amor (whose name was later used for the Amor asteroids) and the Apollo asteroid, 2101 Adonis. Delporte discovered some comets as well, including periodic comet, 57P/du Toit-Neujmin-Delporte. He worked in the Observatoire Royal de Belgique (Belgian Royal Observatory), located in the town of Uccle (which was used to name 1276 Ucclia).
The crater Delporte on the Moon is named after Eugène Delporte.
Apollo asteroids
The Apollo asteroids are a group of asteroids near Earth named after 1862 Apollo, the first asteroid of this group to be discovered by Karl Wilhelm Reinmuth. They are asteroids that cross Earth. Some of these asteroids can get very close to the Earth, making them a potential threat to our planet.
Well-known Apollo asteroids include:
Perpetual motion
Perpetual motion refers to a movement that goes on forever once started without additional energy added. A machine that could be set in motion once would continue to move forever. Such a device or system would be against the law of conservation of energy. This law states that energy cannot be created, or destroyed, but one form of energy can be transformed into a different one.
Perpetual motion machines have interested inventors for a long time, and even though it has been shown that such a machine cannot exist, people still try to build them.
Perpetual motion machines have been classified into different types. Each type breaks a different law of thermodynamics:
RPG Maker
The RPG Maker is a software which can be used to develop RPG (Role Playing Game) games easily even for people that are not experienced in game design (making games). Until 2003 the program has been created by the Japanese company ASCII. From then on Enterbrain continued the development. The RPG Maker has a Graphical User Interface (GUI) which makes operating very simple. The software contains many options to customize a game. Within every version is a Run Time Package (RTP). The RTP contains many different graphics and sounds, although self-created files can be imported into the program as long as they are in the correct format(size, type of file, ...).
"Vampires Dawn" "by Marlex"
It is the most successful RPG Maker game that has ever been developed in Germany. Many local magazines (Screenfun, Gamestar) wrote about this game. At first Vampires Dawn has been made for the computer like all RPG Maker games. After that Marlex developed another game about vampires for mobile phones. Currently an independent company called Clockstone is working on a release of Vampires Dawn for the Nintendo Dual Core.
"Velsarbor" "by Lachsen"
This is a demonstration of a high level of the technical power of the RPG Maker 2000. Lachsen is known to be one of the best coders in the German scene.
"Final Fantasy 0" "by nhard"
This is a demonstration of a high level of the mental power of the MMORPG Maker 2010.
Pine hawk-moth
The pine hawk-moth "(Sphinx pinastri)" is a moth of the family Sphingidae. It is found in Palearctic ecozone and sometimes the Nearctic ecozone. This species has been found in Scotland but is usually found in England. It is amongst the most common moths in many parts of Europe and the Middle East.
The larvae feed on Scots pine, Swiss pine, Siberian pine and Norway spruce.
"Sphinx pinastri's" wings are gray with black dashes. The wingspan is 2 3/4 - 3 1/2 inches (7–9 cm). The moth flies from April to August depending on the location.
The back of the thorax is grey with two dark bands around both sides.
The females lay their eggs in groups of 2 or 3 along pine or spruce needles.
Tropical Storm Laura (2008)
Tropical Storm Laura was the twelfth named storm of the 2008 Atlantic hurricane season. Laura formed out of a large non-tropical low pressure area 1015 miles (1635 km) west of the western islands of the Azores on September 29. Laura slowly got tropical characteristics throughout the day as it moved over warmer waters. On the afternoon of September 30, Laura had gotten enough tropical characteristics to be designated as a "Tropical Storm". Soon after becoming tropical, Laura began to start an extratropical transition, which did not completely take place until the morning of October 1. Laura became reduced into a post-tropical cyclone later that morning, and the National Hurricane Center gave out its last advisory on the storm.
In late September, a large non-tropical system over the north-central Atlantic slowly moved westward away from the Azores. The low produced hurricane-force winds, but did not exhibit the characteristics of a tropical cyclone. The storm steadily weakened over the following days, but developed tropical characteristics as it moved over slightly warmer waters. By September 29, the low had developed sufficient convection and was declared Subtropical Storm Laura. Upon being upgraded, cold cloud tops began to wrap around the center of Laura and consolidate near the center of circulation. The convection organized around the center quickly and a satellite pass over the storm revealed that it could be intensifying. A later satellite pass disregarded the possibility of intensification as the intensity was confirmed to be at 60 mph (95 km/h).
The overall structure of Laura remained subtropical but there were indications that it was acquiring tropical characteristics. During the afternoon, satellites revealed that Laura had developed a deep warm core, a characteristic of a tropical cyclone, but the wind field remained subtropical in nature. By the nighttime hours, the radius of the strongest winds contracted to 80 mi (130 km), much smaller than what is typical of a subtropical cyclone. However, Laura was still under the influence of an upper-level low and cloud tops remained shallow. However, the cloud tops became colder overnight and Laura was on the verge of becoming a tropical cyclone by the morning of September 30, but strong interaction with the upper-level low meant it was still subtropical. Despite moving over colder waters, a water vapor satellite image determined that Laura had separated itself from the upper-level low, signifying it had developed into a tropical cyclone. Laura was upgraded to a tropical storm at a relatively high latitude, 41.2°N.
Not long after being declared tropical, early signs of an extratropical transition appeared. Cold air began to enter the storm on the west side and forecast models showed Laura becoming extratropical the next morning and non-tropical later the next day. Overnight, convection associated with Laura began to diminish and lose tropical characteristics, but still retained its status. Early on October 1, the extratropical transition was fully apparent. Laura remained tropical but the cloud pattern was becoming frontal and there was little convection around the center of the system. Laura later degenerated into a post-tropical cyclone, a term that had been previously used by the Canadian Hurricane Centre to describe a storm that has lost tropical characteristics, but is not subtropical or extratropical. The transition was forecasted to be complete by the end of the day.
