RAP99

The RAM P99 is a paintball marker manufactured by Chinese company Qian Wei and distributed in the United States by Umarex USA under the "Real Action Markers" brand. It is distributed in Europe by Umarex, Germany. The RAM P99 is made under license and designed to replicate the Walther P99.

Operation

Powered by a 12g disposable CO₂ cartridge or re-fillable internal air system, it features a blowback design and 9 shot capacity magazine using .43 caliber paintballs or rubberballs. The trigger is double-action (DA/SA). First versions did not have a conventional on/off safety. Current versions now have a manual trigger-lock safety. The marker is cocked by working the slide and there is also a functional de-cocker. It differs from the RAP4/5 system as it does not use (and therefore) eject shell casings. Muzzle velocity is adjustable between 200 ft/s and 300 ft/s. For .43 cal paintball - 0.029 oz it is about 3.4371 J (at 300 ft/s).

Use

The RAM P99 looks, feels and shoots with great accuracy just like the Walther P99 firearm making it ideal for law enforcement and military training, especially close quarter battles and room clearings. The RAM P99 is also used for virtual reality paintball play.

Rap1

Rap1 (Ras-proximate-1 or Ras-related protein 1) is a small GTPase, which are small cytosolic proteins that act like cellular switches and are vital for effective signal transduction. There are two isoforms of the Rap1 protein, each encoded by a separate gene, RAP1A and RAP1B. Rap1 belongs to Ras-related protein family.

GTPases are inactive when in their GDP-bound form, and become active when they bind to GTP. GTPase activating proteins (GAPs) and guanine nucleotide exchange factors (GEFs) regulate small GTPases, with GAPs promoting the GDP-bound (inactive) form, and GEFs promoting the GTP-bound (active) form. When bound to GTP, small GTPases regulate myriad cellular processes. These proteins are divided into families depending on their protein structure, and the most well studied is the Ras superfamily, of which Rap1 is a member. Whereas Ras is known for its role in cell proliferation and survival, Rap1 is predominantly involved in cell adhesion and cell junction formation. Ras and Rap are regulated by different sets of guanine nucleotide exchange factors and GTPase-activating proteins, thus providing one level of specificity.

Rap6

RAP6 is the abbreviation for Rab5-activating protein 6, a novel endosomal protein with a role in endocytosis. RAP6 was discovered by Alejandro Barbieri and his group of researchers (Christine Hunker, Adriana Galvis, Ivan Kruk, Hugo Giambini, Lina Torres and Maria Luisa Veisaga) working at Florida International University.

This novel human protein has been reported to be involved in membrane trafficking. It has been shown that RAP6 has a guanine nucleotide exchange factor (GEF) activity specific to Rab5 and a GTPase activating protein (GAP) activity specific to RAS.

The original GeneBank Identifications (GIs) have been published in the NCBI Nucleotide databases with GIs 77176718 and 77176720. Since then, many names have been coined to the validated protein such as RabGEF1, GeneID: 27342. RAP6 belongs to the family of the GAPVD1, GeneID: 26130

Cloud (music)

In music a cloud is a sound mass consisting of statistical clouds of microsounds and characterized first by the set of elements used in the texture, secondly density, including rhythmic and pitch density . Clouds may include ambiguity of rhythmic foreground and background or rhythmic hierarchy.

Examples include:

Clouds are created and used often in granular synthesis. Musical clouds exist on the "meso" or formal time scale. Clouds allow for the interpentration of sound masses first described by Edgard Varèse including smooth mutation (through crossfade), disintegration, and coalescence.

Curtis Roads suggests a taxonomy of cloud morphology based on atmospheric clouds: cumulus, stratocumulus, stratus, nimbostratus, and cirrus; as well as nebulae: dark or glowing, amorphus or ring-shaped, and constantly evolving.

Cloud (dancer)

Daniel "Cloud" Campos (born May 6, 1983) is an award-winning Los Angeles-based dancer, director, and occasional actor raised in San Diego, California and Orlando, Florida.

Early life

Cloud started dancing as a b-boy when he was 11. He learned breaking from his oldest brother Kevin "Deft-1" Campos who is also a b-boy. He spent his early life in San Diego then moved to Florida when he was 12. During his time in Florida he toured with High Voltage extreme acrobatics dance team and became a member of Skill Methodz b-boy crew, which was founded in 1995 in Tampa under the name B-Boy Connection. He described what his b-boy name means in an 2011 interview with KoreanRoc.com:

Dance career

After moving to Los Angeles to pursue a career in the dance industry, he booked two tours with Madonna; first in 2004 on her Re-Invention World Tour and again in 2006 on her Confessions Tour. He also performed in the stage show Groovaloos. In 2009, he won first place with his crew Skill Methodz at the UK B-Boy Championships. Later the same year, he competed at Red Bull BC One and appeared in Shakira's music video "Did It Again" as the principal male dancer. In 2010, he appeared in the online series The LXD as The Illister and played the antagonist, Kid Darkness, in the film Step Up 3D. In 2011, he served as one of ten choreographers for Michael Jackson: The Immortal World Tour.

Cloud, California

Cloud is a former settlement in Kings County, California. It was located 35 miles (56 km) southwest of Lemoore.

A post office operated at Cloud from 1913 to 1921.
