Eye

Eyes are the organs of vision. They detect light and convert it into electro-chemical impulses in neurons. In higher organisms, the eye is a complex optical system which collects light from the surrounding environment, regulates its intensity through a diaphragm, focuses it through an adjustable assembly of lenses to form an image, converts this image into a set of electrical signals, and transmits these signals to the brain through complex neural pathways that connect the eye via the optic nerve to the visual cortex and other areas of the brain. Eyes with resolving power have come in ten fundamentally different forms, and 96% of animal species possess a complex optical system. Image-resolving eyes are present in molluscs, chordates and arthropods.

The simplest "eyes", such as those in microorganisms, do nothing but detect whether the surroundings are light or dark, which is sufficient for the entrainment of circadian rhythms. From more complex eyes, retinal photosensitive ganglion cells send signals along the retinohypothalamic tract to the suprachiasmatic nuclei to effect circadian adjustment and to the pretectal area to control the pupillary light reflex.

Eyes (video game)

Eyes is an arcade game released in 1982 by Rock-Ola.

Gameplay

The player controls a hat-wearing eyeball in a maze. As in Pac-Man the goal is to collect all of the dots to advance to next level, but in Eyes you shoot the dots rather than eat them. Computer-controlled eyes chase and shoot at the player. Shooting a computer eye gives points and removes it from the level, but it will reappear a short time later. Being shot by a computer eye is fatal.

As the game progresses, more computer eyes are added to levels and they take less time to shoot at the player. They also move faster.

Eyes Galaxies

The Eyes Galaxies (NGC 4435-NGC 4438, also known as Arp 120) are a pair of galaxies about 52 million light-years away in the constellation Virgo. This galaxy takes its name from its ring structure which made it popular.

NGC 4435

NGC 4435 is a barred lenticular galaxy with a relatively young (age of 190 million years) stellar population on its central regions that has been discovered by the Spitzer Space Telescope and whose origin may be the interaction with NGC 4438. It also has a long tidal tail possibly caused by the interaction with the mentioned galaxy; however other studies suggest that tail is actually a galactic cirrus in the Milky Way totally unrelated to NGC 4435.

NGC 4438

NGC 4438 is the most curious interacting galaxy in the Virgo Cluster, due to the uncertainty surrounding the energy mechanism that heats the nuclear source; this energy mechanism may be a starburst region, or a black hole powered active galactic nucleus (AGN). Both of the hypotheses are still being investigated.

Frontline (band)

Frontline are a New Zealand hip hop music group formed in 2001.

History

The New Zealand hip hop group known as 'Frontline' is a two man hip hop team: Samoan-European MC David Dallas (also known as Con Psy) and producer and DJ Nick Maclaren DJ 41:30. Con Psy won the 2003 Auckland MC Battle For Supremacy and 41 has won the 2000 Auckland ITF Championships.

After meeting in 2001 in Auckland, the pair formed some tracks together & released a mixtape What You Expect?. During this time Maclaren produced tracks for the likes of the Deceptikonz, Mareko and more while Dallas completed a BSc in computing. Without any formal broadcasting or distribution, it sold over 1000 copies.

The duo hooked up with premier New Zealand DJ P Money (also known as Peter Wadams).He signed Frontline to his co-owned record label Dirty Records. He then offered Dallas' skills to Scribe's multi#1 single "Not Many-The Remix!" featured on Scribe's five times platinum album The Crusader.

In 2004, P-Money's second album Magic City saw three appearances by Dallas; "Get Up Slow", "Get Back" (also featuring Dirty Records labelmate PNC) & "321 Remix" (also featuring Skillz & PNC). He also appears on the Breakin Wreckwordz mixtapes Breakin Wreckwordz Vol 1. & Fuck Music, Sirvere's Major Flavours collective & Breakinwreck artist Louie Knuxx's album Wasted Youth. 41 produced PNC's mixtape Ohhhhh On The PNC Tip.

Frontline (season 2)

This is a list of the 13 episodes of series two of Frontline, which first aired in 1995. In series 2, Frontline (the fictional show-within-the-show) struggles with ratings, and the network's varying attempts to heighten the ratings. The series is shot in mockumentary style. All of the show's episodes were written and directed by Rob Sitch (Mike Moore), Jane Kennedy (Brooke Vandenberg), Santo Cilauro (Geoffrey Salter) – who also did most of the camera work – and Tom Gleisner.

Fipronil

Fipronil is a broad-use insecticide that belongs to the phenylpyrazole chemical family. Fipronil is a broad-spectrum insecticide that disrupts the insect central nervous system by blocking GABA-gated chloride channels and glutamate-gated chloride (GluCl) channels, resulting in central nervous system toxicity. This causes hyperexcitation of contaminated insects' nerves and muscles. Specificity of fipronil on insects may come from a better efficacy on GABA receptor, but also because GluCl channels do not exist in mammals.

Effects

Fipronil is a slow acting poison. When used as bait, it allows the poisoned insect time to return to the colony or harborage. In cockroaches, the feces and carcass can contain sufficient residual pesticide to kill others in the same nesting site. In ants, the sharing of the bait among colony members assists in the spreading of the poison throughout the colony. With the cascading effect, the projected kill rate is about 95% in three days for ants and cockroaches. Fipronil serves as a good bait toxin not only because of its slow action, but also because most, if not all, of the target insects do not find it offensive or repulsive.

Lightning (Revere Beach)

Lightning was a wooden roller coaster that operated at Revere Beach in Revere, Massachusetts from 1927 until 1933. It was one of the infamous Giant Cyclone Safety Coasters which were constructed by noted roller coaster engineer Harry G. Traver in the mid-1920s (the rides were, in fact, anything but safe, and became known as the "terrifying triplets"). Lightning was the only Giant Cyclone Safety Coaster not to bear the "Cyclone" name, as a roller coaster named Cyclone already existed at Revere Beach when Lightning was constructed in 1927. The other two members of this group of coasters included the Crystal Beach Cyclone and the Palisades Park Cyclone (A fourth Traver roller coaster named Zip had a similar—but smaller—design and was installed at Oaks Amusement Park in Portland, Oregon).

Ride layout and structure

Although the precise dimensions of Lightning are not reported, its common design heritage with the Crystal Beach Cyclone suggests that these coasters share many technical specifications, such as heights around 100 feet (30 m), many steeply-banked turns and a ground-level figure 8 track. In fact, there was no truly straight track apart from the station. Lightning's hybrid steel structure allowed for much more steeply banked curves than would have been possible in an ordinary wooden-framed roller coaster of the day. These steeply banked tracks often made quick transitions to steep banks in the opposite directions. These quick rolling transitions were one of the primary reasons for the violent nature of the Lightning.
