Fish tape

A fish tape (also known as a draw wire or draw tape) is a tool used by electricians to route new wiring through walls and electrical conduit.

Made of a narrow band of spring steel, by careful manipulation, the tape can be guided through confined spaces such as wall cavities. The goal is to push toward an area where guide string has been dropped inside the confined space and to pull it through, so the guide string can then be used to pull through various types of wiring, such as phone wire, network cables or speaker wire. Fish tape is designed to pull through guide string only. Using it to directly pull the target wire can damage or warp the fish tape.

Design

Fish tapes are usually stored coiled on a plastic reel. Because of this, they have a natural curvature and it is this curvature that allows them to be guided. By manipulating the reel, the end of the tape can be directed slightly. The tape is rigid enough that it can then be pushed in the direction in which it is pointing. In this way it can be easily guided through an empty wall cavity. Thermal insulation, firestops, pipes, HVAC ducts, electrical conduits, and other obstructions make use of a fish tape more challenging.

Jasper Fish

Jasper Fish (buried 28 July 1791 at Sevenoaks, Kent) was a noted professional cricketer in the 18th century who was chiefly associated with Kent in the 1760s and 1770s.

Most of his career took place before cricket's statistical record began with regular scorecards in 1772 and he is recorded in only three major cricket matches in 1769, 1773 and 1777.

Fish anatomy

Fish anatomy is the study of the form or morphology of fishes. It can be contrasted with fish physiology, which is the study of how the component parts of fish function together in the living fish. In practice, fish anatomy and fish physiology complement each other, the former dealing with the structure of a fish, its organs or component parts and how they are put together, such as might be observed on the dissecting table or under the microscope, and the latter dealing with how those components function together in the living fish.

The anatomy of fish is often shaped by the physical characteristics of water, the medium in which fish live. Water is much denser than air, holds a relatively small amount of dissolved oxygen, and absorbs more light than air does. The body of a fish is divided into a head, trunk and tail, although the divisions between the three are not always externally visible. The skeleton, which forms the support structure inside the fish, is either made of cartilage, in cartilaginous fish, or bone in bony fish. The main skeletal element is the vertebral column, composed of articulating vertebrae which are lightweight yet strong. The ribs attach to the spine and there are no limbs or limb girdles. The main external features of the fish, the fins, are composed of either bony or soft spines called rays, which with the exception of the caudal fins, have no direct connection with the spine. They are supported by the muscles which compose the main part of the trunk. The heart has two chambers and pumps the blood through the respiratory surfaces of the gills and on round the body in a single circulatory loop. The eyes are adapted for seeing underwater and have only local vision. There is an inner ear but no external or middle ear. Low frequency vibrations are detected by the lateral line system of sense organs that run along the length of the sides of fish, and these respond to nearby movements and to changes in water pressure.

Fish physiology

Fish physiology is the scientific study of how the component parts of fish function together in the living fish. It can be contrasted with fish anatomy, which is the study of the form or morphology of fishes. In practice, fish anatomy and physiology complement each other, the former dealing with the structure of a fish, its organs or component parts and how they are put together, such as might be observed on the dissecting table or under the microscope, and the later dealing with how those components function together in the living fish.

Respiration

Most fish exchange gases using gills on either side of the pharynx (throat). Gills are tissues which consist of threadlike structures called filaments. These filaments have many functions and "are involved in ion and water transfer as well as oxygen, carbon dioxide, acid and ammonia exchange. Each filament contains a capillary network that provides a large surface area for exchanging oxygen and carbon dioxide. Fish exchange gases by pulling oxygen-rich water through their mouths and pumping it over their gills. In some fish, capillary blood flows in the opposite direction to the water, causing countercurrent exchange. The gills push the oxygen-poor water out through openings in the sides of the pharynx.

Tape (play)

Tape is a 1999 play by Stephen Belber. It was first produced at the Actors Theatre of Louisville as part of the 2000 Humana Festival of New American Plays. It was later filmed by Richard Linklater as Tape starring Ethan Hawke, Robert Sean Leonard, and Uma Thurman. It follows classical unities of action, time and space, featuring three characters in a single plot (narrative) regarding their differing perspectives of past events, in one unbroken period of real-time, in a single motel room set.

Synopsis

Tape is set in a motel room in Lansing, Michigan. Vince, an outgoing drug dealer/volunteer firefighter, is in town to support his old high school friend’s entry into the Lansing film festival.

His friend, documentary filmmaker Jon Saltzman, joins Vince in his motel room and the two begin to reminisce about their high school years. They get on the subject of Amy Randall, Vince's former girlfriend. It appears that whilst they dated for some time, Vince and Amy never had sex. However, after their relationship had ended, Amy had slept with Jon. Naturally, Vince was hurt even though he and Amy had broken up some time previously.

Tape (film)

Tape is a 2001 American camcorder drama film directed by Richard Linklater and written by Stephen Belber, based on his play of the same name. It stars Ethan Hawke, Robert Sean Leonard, and Uma Thurman. The entire film takes place in real time.

Plot

The entire film is set inside a Lansing, Michigan motel room. Vince, a drug dealer/volunteer firefighter from Oakland, rents the room in his hometown to support his old high school friend's entry into the Lansing Film Festival.

His friend, documentary filmmaker Jon Salter, joins Vince in his motel room and the two reminisce about their high school years. At first, the two are happy to see one another, but friction soon develops. Eventually, they get on the subject of Amy, Vince's former girlfriend. It appears that, while they dated for some time, Vince and Amy never had sex. However, after or at the point when their relationship had ended, Amy slept with Jon.

Vince claims Amy had told him that Jon had raped her. Vince becomes obsessed with, and eventually succeeds in getting a verbal confession from Jon. Immediately after Jon's admission, Vince pulls out a hidden tape recorder that had been recording their whole conversation, much to Jon's horror. Vince then tells Jon that he has invited Amy to dinner, and that she will be arriving shortly.
