They prefer lived-in bedding (up to two weeks old - longer durations were not tested) over new bedding, suggesting they may prefer bedding changes at two-week intervals rather than weekly or daily. They also prefer opaque tubes closed at one end, 15 cm in diameter, to use as shelter in which to nest and sleep.

The characteristic feature of this boiler are its 'thimble tubes'. These are short horizontal water tubes, closed at one end and tapered. They are thus similar to the field-tube boiler, which also uses single-ended closed tubes, but with important differences. The field-tube boiler uses downward-pointing vertical tubes and these also have an internal tube.

For Syrian hamsters, a diameter of 9 inches is a minimum (studies have found that they prefer 14 inches. The running surface cannot be wire or mesh because that can cause bumblefoot.) Silent spinner wheels are a good alternative. The cage should also provide a sheltering structure for sleeping; this can be as simple as an opaque tube closed at one end.

The three orders of thaliaceans are filter feeders. Pyrosomes are colonial animals, with multiple tiny ascidian-like zooids arranged in a cylinder closed at one end. All of the atrial siphons point inwards, emptying into a single, common cloaca in the centre of the cylinder. As the water exhaled by the zooids exits through a common opening, the water movement slowly propels the pyrosome through the sea.

A red-colored post pounder next to two green steel t-posts A post pounder, post driver, post rammer, post knocker or fence driver is a tool used for driving fence posts and similar items into land surfaces. It consists of a heavy steel pipe which is closed at one end and has handles welded onto the sides. It is normally used by one person, but larger versions may require two.

In biology, a lorica is a shell-like protective outer covering, often reinforced with sand grains and other particles that some protozoans and loriciferan animals secrete. Usually it is tubular or conical in shape, with a loose case that is closed at one end. An example is the protozoan genus Stentor, in which the lorica is trumpet-shaped. In the tintinnids, the lorica is frequently transparent and is used as domicile.

The cartridge is extremely simple in construction and does not look like a real cartridge at all. It is typically just a single-piece brass open "tube" closed at one end with a machined extractor groove, thus also known as open cartridge. The cap is plugged deep into bottom of the cartridge and fired by a thick detonator pin. The exploded pressure between detonator pin and bottom of cartridge produces the blowback effect.

Rocket engines were also brought in use by Tippu Sultan, the king of Mysore. These rockets could be of various sizes, but usually consisted of a tube of soft hammered iron about long and diameter, closed at one end and strapped to a shaft of bamboo about long. The iron tube acted as a combustion chamber and contained well packed black powder propellant. A rocket carrying about one pound of powder could travel almost .

Rondador The rondador is a set of chorded cane panpipes that produces two tones simultaneously. It consists of pieces of cane, placed side by side in order by size and closed at one end, and is played by blowing across the top of the instrument. The rondador is considered the national instrument of Ecuador. Further knowledge on the instrument is required, as the musical scale of which note each tube played projects is unknown.

The spinning-rotor gauge works by measuring the amount a rotating ball is slowed by the viscosity of the gas being measured. The ball is made of steel and is magnetically levitated inside a steel tube closed at one end and exposed to the gas to be measured at the other. The ball is brought up to speed (about 2500 rad/s), and the speed measured after switching off the drive, by electromagnetic transducers.A. Chambers, Basic Vacuum Technology, pp.

The mortar consists of a steel tube closed at one end by a steel base-plate, which rests on a wooden platform. The , , shells fit around and on top of the tube, instead of being dropped inside, making this a spigot mortar. The range of each shot was adjusted by adding different size powder charges at the base of the round. The barrels could only handle five or six shots apiece before becoming damaged and unusable.

The Culverin was an opposed-piston, two-stroke design. Instead of each cylinder having a single piston and being closed at one end with a cylinder head, the Jumo-based design used an elongated cylinder containing two pistons moving in opposite directions towards the centre. This obviates the need for a heavy cylinder head, as the opposing piston filled this role. On the downside, the layout required separate crankshafts on each end of the engine that must be coupled through gearing or shafts.

A hot-tube ignitor was an early device that fit onto the cylinder head of an internal-combustion engine, used to ignite the compressed fuel/air mixture by means of a flame heating part of the tube red-hot. A hot-tube ignitor consisted of a metal or porcelain tube, closed at one end and attached to the cylinder head at the other and an adjustable burner that could be moved to position its flame at any point along the length of the tube.

Pyramidal horn antennas for a variety of frequencies. They have flanges at the top to attach to standard waveguides. A horn antenna is used to transmit radio waves from a waveguide (a metal pipe used to carry radio waves) out into space, or collect radio waves into a waveguide for reception. It typically consists of a short length of rectangular or cylindrical metal tube (the waveguide), closed at one end, flaring into an open-ended conical or pyramidal shaped horn on the other end.

These changes are predictable. The vocal tract can be modeled as a sequence of tubes, closed at one end, with varying diameters, and by using equations for acoustic resonance the acoustic effect of an articulatory posture can be derived. The process of inverse filtering uses this principle to analyze the source spectrum produced by the vocal folds during voicing. By taking the inverse of a predicted filter, the acoustic effect of the supraglottal vocal tract can be undone giving the acoustic spectrum produced by the vocal folds.

Field tube, sectioned A Field-tube boiler (also known as a bayonet tube) is a form of water-tube boiler where the water tubes are single-ended. The tubes are closed at one end, and they contain a concentric inner tube. Flow is thus separated into the colder inner flow down the tube and the heated flow upwards through the outer sleeve. As Field tubes are thus dependent on thermo-syphon flow within the tube, they must thus always have some vertical height to encourage the flow.

Thermowells are cylindrical fittings used to protect temperature sensors installed in industrial processes. A thermowell consists of a tube closed at one end and mounted in the process stream. A temperature sensor such as a thermometer, thermocouple, or resistance temperature detector is inserted in the open end of the tube, which is usually in the open air outside the process piping or vessel and any thermal insulation. Thermodynamically, the process fluid transfers heat to the thermowell wall, which in turn transfers heat to the sensor.

Specialty heat- shrink tubing, known as "solder sleeves", have a tube of solder inside of the heat-shrink tubing, allowing the heat source to electrically join the two wires by melting the solder and simultaneously insulate the junction with the tubing. Solder sleeves also commonly contain a ring of heat-activated sealant on the inside of each end of the tubing, allowing the connection to also be made waterproof. Heat-shrink end caps, closed at one end, are used to insulate the exposed cut ends of insulated wires.

The earliest barometers were simply glass tubes that were closed at one end and filled with mercury. The tube was then inverted and its open end was submerged in a cup of mercury. The mercury then drained out of the tube until the pressure of the mercury in the tube — as measured at the surface of the mercury in the cup — equaled the atmosphere's pressure on the same surface. In order to produce barometric light, the glass tube must be very clean and the mercury must be pure.

In addition, wheeled rocket launchers were used in war that were capable of launching five to ten rockets almost simultaneously. Rockets could be of various sizes but usually consisted of a tube of soft hammered iron about long and 1.5 to 3 in (3.8 to 7.6 cm) in diameter, closed at one end and strapped to a shaft of bamboo about long. The iron tube acted as a combustion chamber and contained well-packed black powder propellant. A rocket carrying about one pound (~500 gm) of powder could travel almost 1,000 yards (~900 m).

He was right. The problem was in creating a copper tube that was "spun" closed at one end, eliminating the need for a soldered, fitted cap. After reading an article in a magazine on spinning copper, Ted Ismert created a breakthrough system for spinning closed copper pipe. (Michigan-based Wolverine Tube had successfully spun closed chambers, but their products were expensive and relegated to the back of their catalog) The swift-selling pre-fabricated air chamber was the major breakthrough that poised Sioux Chief on the brink of lasting success.

The lymphatic circulation begins with blind ending (closed at one end) highly permeable superficial lymph capillaries, formed by endothelial cells with button-like junctions between them that allow fluid to pass through them when the interstitial pressure is sufficiently high. These button-like junctions consist of protein filaments like platelet endothelial cell adhesion molecule-1, or PECAM-1. A valve system in place here prevents the absorbed lymph from leaking back into the ISF. There is another system of semilunar (semi=half; lunar=related to the Moon) valves that prevents back-flow of lymph along the lumen of the vessel.

A Torricellian vacuum is created by filling a tall glass container closed at one end with mercury, and then inverting it in a bowl to contain the mercury (see below).How to Make an Experimental Geissler Tube, Popular Science monthly, February 1919, Unnumbered page. Bonnier Corporation Vacuum became a valuable industrial tool in the 20th century with the introduction of incandescent light bulbs and vacuum tubes, and a wide array of vacuum technologies has since become available. The recent development of human spaceflight has raised interest in the impact of vacuum on human health, and on life forms in general.

The oldest and simplest type of cap, fuse caps are a metal cylinder, closed at one end. From the open end inwards, there is first an empty space into which a pyrotechnic fuse is inserted and crimped, then a pyrotechnic ignition mix, a primary explosive, and then the main detonating explosive charge. The primary hazard of pyrotechnic blasting caps is that for proper usage, the fuse must be inserted and then crimped into place by crushing the base of the cap around the fuse. If the tool used to crimp the cap is used too close to the explosives, the primary explosive compound can detonate during crimping.

Hyder Ali and his son Tipu Sultan organized rocket artillery brigades, or "cushoons", against the British East India Company during the Anglo-Mysore Wars. The rocket men were trained to launch their rockets at an angle calculated from the diameter of the cylinder and the distance of the target. In addition, wheeled rocket launchers were used in war that were capable of launching five to ten rockets almost simultaneously. Rockets could be of various sizes, but usually consisted of a tube of soft hammered iron about long and diameter, closed at one end and strapped to a shaft of bamboo about 4 ft long.

The resonance of a tube of air is related to the length of the tube, its shape, and whether it has closed or open ends. Many musical instruments resemble tubes that are conical or cylindrical (see bore). A pipe that is closed at one end and open at the other is said to be stopped or closed while an open pipe is open at both ends. Modern orchestral flutes behave as open cylindrical pipes; clarinets behave as closed cylindrical pipes; and saxophones, oboes, and bassoons as closed conical pipes, while most modern lip-reed instruments (brass instruments) are acoustically similar to closed conical pipes with some deviations (see pedal tones and false tones).

When used in an organ a tube which is closed at one end is called a "stopped pipe". Such cylinders have a fundamental frequency but can be overblown to produce other higher frequencies or notes. These overblown registers can be tuned by using different degrees of conical taper. A closed tube resonates at the same fundamental frequency as an open tube twice its length, with a wavelength equal to four times its length. In a closed tube, a displacement node, or point of no vibration, always appears at the closed end and if the tube is resonating, it will have an antinode, or point greatest vibration at the Phi point (length × 0.618) near the open end.

Culdoscope is an instrument, a kind of endoscope, used to visualize female pelvic organs, introduced through the vagina into the cul-de-sac (which is also called the rectouterine pouch or the pouch of Douglas). The procedure of inserting the culdoscope into the rectouterine pouch is termed culdoscopy. The word culdoscope (and culdoscopy) is derived from the phrase cul-de-sac, which in French literally means "bottom of a sac", here referring to a blind pouch or cavity in the female body that is closed at one end, that is the rectouterine pouch. As early as the 13th century, a cul-de-sac was a dead-end street (or a dead-end way), a blind alley.

Glass-coating is a process invented in 1924 by G. F. Taylor and converted into production machine by Ulitovski for producing fine glass-coated metal filaments only a few micrometres in diameter. In this process, known as the "Taylor-wire" or "microwire process" or "Taylor-Ulitovski process", the metal to be produced in microwire form is held in a glass tube, typically a borosilicate composition, which is closed at one end. This end of the tube is then heated in order to soften the glass to a temperature at which the metal part is in liquid state and the glass can be drawn down to produce a fine glass capillary containing a metal core. In recent years the process was converted to continuous one by continuously feeding the metal drop with new material.

Even- numbered string harmonics from 2nd up to the 64th (5 octaves). One of the simplest cases to visualise is a vibrating string, as in the illustration; the string has fixed points at each end, and each harmonic mode divides it into 1, 2, 3, 4, etc., equal-sized sections resonating at increasingly higher frequencies. Similar arguments apply to vibrating air columns in wind instruments (for example, "the French horn was originally a valveless instrument that could play only the notes of the harmonic series"), although these are complicated by having the possibility of anti-nodes (that is, the air column is closed at one end and open at the other), conical as opposed to cylindrical bores, or end-openings that run the gamut from no flare, cone flare, or exponentially shaped flares (such as in various bells).
