Superfluidity is only observed "naturally" in two liquids: helium-4 and the rarer isotope, helium-3. Quantum turbulence was first discovered in pure 4He in a counterflow (where the normal and superfluid components are made to flow in opposite directions) generated by a steady heat current. See superfluid helium-4. Since the two-fluid model, and therefore counterflow itself, is unique to superfluids, this counterflow turbulence is not observed classically; the first observations of turbulence with direct classical counterparts has come much more recently through the investigation of pressure fluctuations in rotational flow and grid turbulence.

Signals that may indicate other conditions for roads without counterflow lanes also exist, such as those that indicate different speed limits for different lanes.

The Faraday disc was primarily inefficient due to counterflows of current. While current flow was induced directly underneath the magnet, the current would circulate backwards in regions outside the influence of the magnetic field. This counterflow limits the power output to the pickup wires, and induces waste heating of the copper disc. Later homopolar generators would solve this problem by using an array of magnets arranged around the disc perimeter to maintain a steady field around the circumference, and eliminate areas where counterflow could occur.

Each of the two spans had two lanes. During the morning and evening commute times, a counterflow lane was opened so that the traffic was three lanes in one direction and one lane in the other.

Counterflow centrifugal elutriation (CCE) is a liquid clarification technique. This method enables scientists to separate different cells with different sizes. Since cell size is correlated with cell cycle stages this method also allows the separation of cells at different stages of the cell cycle.

The Alex Fraser Bridge is long with a main span of . The towers are tall.Buckland & Taylor project page, lists design facts about the bridge It consists of seven lanes, three in each direction with the middle lane acted as the counterflow lane, and has a maximum speed limit of 90 km per hour until July 24, 2019 when the speed limit was lowered to 70 km/h to accommodate the additional counterflow lane.Alex Fraser Bridge speed limit permanently lowered to 70 km/hrSpeed limit on Alex Fraser Bridge being permanently lowered buy 20 km/h Upon opening in 1986, only four of the six available lanes were open.

Portions of the system give a rather strong "water flowing uphill" illusion, owing to the controlled gentle slopes and the nature of the adjacent terrain. Additional associated structures include a long aqueduct crossing a saddle, a deep and long cut, and an upcanyon routed "counterflow" canal segment.

There is often congestion with tailbacks at the weekends, especially on Sunday evenings. Due to its sharp turns with restricted headroom, high-sided vehicles can only use the left-hand lane of the western tunnel, so it was not possible to reverse the tidal flow in the evening. In April 2007, the morning tidal flow was discontinued, after reports by TfL and the Metropolitan Police (MPS) of an increase in dangerous motoring behaviour; these blamed poor driving, such as overtaking, for the decrease in safety during counterflow operations. The decision to end the counterflow was controversial, particularly as TfL and the MPS had been considering it since 2005, without properly informing affected borough councils, and an independent committee was set up to evaluate the decision.

In simple words, the liquid is cooled by evaporating a part of it. In the sugar industry, vertical cooling crystallizers are used to exhaust the molasses in the last crystallization stage downstream of vacuum pans, prior to centrifugation. The massecuite enters the crystallizers at the top, and cooling water is pumped through pipes in counterflow.

Product and cooling air pass through the cooler in counterflow. The product to be cooled falls directly into the product feed housing. By the rotary movement and a little slope of the rotor, the product is conveyed through the cooler. The rotation causes a permanent mixing of the product in the tubes and hence a good heat transfer.

The mass fraction of species and temperature fields can be measured or calculated in laminar counterflow diffusion flame experiments. When calculated, a self-similar solution exists, and the governing equations can be simplified to only one dimension i.e. along the axis of the fuel and oxidizer jets. It is in this direction where complex chemistry calculations can be performed affordably.

Known classically as the "counterflow 8 valve", the EA827 engine series is the root of most of Volkswagen's engines in the 1970s, 1980s and 1990s. It started as an Audi-designed engine and spawned straight-five- cylinder, diesel, crossflow, turbo, supercharged, and 16 valve variants. While mostly retired, the "second cousin" of the EA827 is still alive, known as the TDI.

Before usage, the Schlenk-frit has to be heated, to remove water traces. The Schlenk-frit is put onto the product flask using an inert gas counterflow and closed at the top end with a second flask. The whole is turned 180° to start filtration. The liquid parts of the reaction mix go through the filter while the solid parts remain.

Volmer's group with Victor Bayerl, a physical chemist and Gustav Richter a physicist, was under Alexander Mikailovich Rosen, and they designed a heavy water production process and facility based on the counterflow of ammonia. The installation was constructed at Norilsk and completed in 1948, after which Volmer's organization was transferred to Zinaida Yershova’s group, which worked on plutonium extraction from fission products.Oleynikov, 2000, 13.

In practice, the uniflow engine has a number of operational shortcomings. The large expansion ratio requires a large cylinder volume. To gain the maximum potential work from the engine a high reciprocation rate is required, typically 80% faster than a double-acting counterflow type engine. This causes the opening times of the inlet valves to be very short, putting great strain on a delicate mechanical part.

The nutrient dissolves in the hotter zone and the saturated aqueous solution in the lower part is transported to the upper part by convective motion of the solution. The cooler and denser solution in the upper part of the autoclave descends while the counterflow of solution ascends. The solution becomes supersaturated in the upper part as the result of the reduction in temperature and crystallization sets in.

It is a simple type of cooler which is widely applied as cryocooler or as the (final stage) of coolants. It can easily be miniaturized, but it is also used on a very large scale in the liquefaction of natural gas. A schematic diagram of a JT liquefier is given in Fig.8. It consists of a compressor, a counterflow heat exchanger, a JT valve, and a reservoir.

T cell depletion methods can be broadly categorized into either physical or immunological. Examples of physical separation include using counterflow centrifugal elutriation, fractionation on density gradients, or the differential agglutination with lectins followed by rosetting with sheep red blood cells. Immunological methods utilize antibodies, either alone, in conjunction with homologous, heterologous, or rabbit complement factors which are directed against the T cells. In addition, these techniques can be used in combinations.

In 1964, the exit 17 rotary was constructed at Newton Corner. Expecting little traffic at the intersection, the trolley tracks were placed in a counterflow lane, while the platforms were moved to the north side of the rotary in a dedicated median. However, the rotary proved to be busy and congested, resulting in frequent delays and automobile-trolley collisions. In 1967, the #69 trolley was renamed as the Green Line A branch.

Bernardus Antonie van Beek (30 January 1875, in Amsterdam - 3 March 1941, in Kortenhoef) was a Dutch landscape painter. He never attended an academy. He was part of the Kortenhoef School, a sub-movement of the Hague School and is thus in the tradition of Barbizon School.The Hague School in The Hague and its surroundings is the place of counterflow to neoclassical painting of the Netherlands and also the central place of origin of the Dutch movement of impressionism.

Heat loss is controlled by reducing the surface to volume ratio, and thick insulating layers of blubber and/or fur, which also help with streamlining for reduced drag. Exposed areas with relatively high circulation may use a rete mirabile counterflow heat exchange system of blood vessels to reduce heat loss. Marine mammals use sound to communicate underwater, and many species use echolocation to navigate and locate prey. Pinnipeds and fissipeds have facial whiskers capable of locating prey by detecting vibrations in the water.

This was not a dynamo in the current sense, because it did not use a commutator. This design was inefficient, due to self-cancelling counterflows of current in regions of the disk that were not under the influence of the magnetic field. While current was induced directly underneath the magnet, the current would circulate backwards in regions that were outside the influence of the magnetic field. This counterflow limited the power output to the pickup wires, and induced waste heating of the copper disc.

The flow of Amsterdamse Joffers is a movement within the Amsterdam Impressionism. Its members, however, have always chosen their own way. Amsterdam Impressionism – sometimes referred to by art historians as the School of Allebé – was the counterflow to the very strong Hague School in the movement of Dutch Impressionism. As a professor at the Royal Academy of Amsterdam (Rijksakademie van beeldende kunsten) he fostered a cosmopolitan attitude toward art and the promotion and motivation of his students, and provided a significant stimulus to developments in modern art.

The flamelet concept considers the turbulent flame as an aggregate of thin, laminar (Re < 2000), locally one-dimensional flamelet structures present within the turbulent flow field. Counterflow diffusion flame is a common laminar flame which is used to represent a flamelet in a turbulent flow. Its geometry consists of opposed and axi-symmetric fuel and oxidizer jets. As the distance between the jets is decreased and/or the velocity of the jets is increased, the flame is strained and departs from its chemical equilibrium until it eventually extinguishes.

Initial capital cost is also higher, however turbine power augmentation and efficiency is maximized, and the extra-cost is amortized due to increased output power. The majority of such systems involve more than one chiller unit and the configuration of the chillers can have a great bearing on the system parasitic power consumption. The series counterflow configuration can reduce the compressor work needed on each chiller, improving the overall chiller system by as much as 8%. Other options such a steam driven compression are also used in industry.

Five Deez's first release was the Secret Agent Number 005 The E.P. on September 27, 2000 on Landspeed Records. This album was a precursor to the first full-length debut Koolmotor released on November 27, 2001 on Counterflow Recordings. Koolmotor (describing the sound of the album, like a "cool motor") contains two songs from Secret Agent Number 005 The E.P., B.E.A.T. and Dope. Koolmotor was released to positive reviews, as critics praised the experimentation of the album and the sound that was radically different from that of other mainstream and underground artists.

Potassium channels function to conduct potassium ions down their electrochemical gradient, doing so both rapidly (up to the diffusion rate of K+ ions in bulk water) and selectively (excluding, most notably, sodium despite the sub- angstrom difference in ionic radius). Biologically, these channels act to set or reset the resting potential in many cells. In excitable cells, such as neurons, the delayed counterflow of potassium ions shapes the action potential. By contributing to the regulation of the action potential duration in cardiac muscle, malfunction of potassium channels may cause life- threatening arrhythmias.

To combat this issue, the BC Government announced that a heavy lift helicopter will be used to blow snow and ice off the cables to prevent it from accumulating and falling onto the cars below. According to an announcement on January 19, 2017, a new lane will be added on the bridge by slightly narrowing the existing lanes and removing the shoulders. A counterflow system with movable barrier will be added to help ease traffic during morning and afternoon rush hours. This will be a joint venture by the provincial and federal government.

In transport engineering nomenclature, a counterflow lane or contraflow lane is a lane in which traffic flows in the opposite direction of the surrounding lanes. Contraflow lanes are often used for bicycles or bus rapid transit on what are otherwise one-way streets. In a sample configuration for buses, a street might have four lanes: the outermost lanes are reserved for buses in both directions, while the center two lanes are available for general traffic in only one direction. Thus, the street functions as two-way for buses, but one-way for all other vehicles.

In addition, since enzymes are small enough to easily move into and out of the peritrophic matrix, they are rarely lost when the matrix, along with its contents still in the endoperitrophic space, is excreted. A counterflow of fluid in the ecoperitrophic space also helps recycle enzymes, thus maximizing their efficacy. The presence of a peritrophic matrix significantly simplifies the excretion process. Rather than having to continually sift through a mixture of digestible and unwanted molecules, digestible molecules are quickly broken down by enzymes, removed from the matrix and absorbed.

The tunnel is a single tube that is subdivided with a concrete wall, each side containing two traffic lanes. The typical traffic flow has two northbound lanes in the east tube and two southbound lanes in the west tube. In 1981 a counterflow system was introduced to meet increasing traffic demand in the tunnel. At peak rush traffic periods, a reversible lane system is used, with a series of swing gates deployed that direct traffic in one direction to a single lane, while increasing the other direction to three lanes.

Central Terminal has a unique layout as it has exits on all of its four corners (serving as two direct exits from each platform), plus two from the concourse level going down to the middle of the ground level. This bring it to a total of five exits and two entrances in the same vicinity. The four corner exits have one-way revolving doors to prevent counterflow entry through these exits. On the other hand, one of the center- located entrances and exits are sealed off as to direct commuters through the other center-located entrance and exit.

Uniflow engines potentially allow greater expansion in a single cylinder without the relatively cool exhaust steam flowing across the hot end of the working cylinder and steam ports of a conventional "counterflow" steam engine during the exhaust stroke. This condition allows higher thermal efficiency. The exhaust ports are only open for a small fraction of the piston stroke, with the exhaust ports closed just after the piston begins traveling toward the admission end of the cylinder. The steam remaining within the cylinder after the exhaust ports are closed is trapped, and this trapped steam is compressed by the returning piston.

In many types of processes, combustion is used to generate heat, and the recuperator serves to recuperate, or reclaim this heat, in order to reuse or recycle it. The term recuperator refers as well to liquid-liquid counterflow heat exchangers used for heat recovery in the chemical and refinery industries and in closed processes such as ammonia-water or LiBr-water absorption refrigeration cycle. Recuperators are often used in association with the burner portion of a heat engine, to increase the overall efficiency. For example, in a gas turbine engine, air is compressed, mixed with fuel, which is then burned and used to drive a turbine.

He has focused his research studies on the basic problems of combustion, both reactor and planetary probe dynamics, in the latter case working directly for NASA and the European Space Agency. Also, his work of applying mathematics to the problems of combustion have been considered pioneers in the world, to the point that the letters of presentation and support of his candidacy for the 1993 Prince of Asturias Awards, coming from universities and Research centers in various countries, do not hesitate to consider it as a relevant world theoretician in the field. The diffusion flame structure in counterflow is thoroughly analyzed by him in 1974 through activation-energy asymptotics.Liñán, Amable.

The new Pitt River Bridge is a seven-lane cable-stayed bridge that carries the Lougheed Highway over the Pitt River; it was built between the two swing bridges that previously performed this duty. A new interchange has replaced the at-grade intersection of the Lougheed Highway and the Mary Hill Bypass. The old swing bridges previously accommodated four lanes of traffic, two on each bridge, with a counterflow system for peak hours. The new bridge carries three lanes of general-purpose traffic in each direction, as well as one eastbound lane for slower-moving trucks accessing the Canadian Pacific intermodal yard at Kennedy Road.

Flashing red is sometimes used instead of yellow. This parking ramp uses lane control signals so that the middle lane's direction may be changed according to time of day. On certain multiple-lane highways, one or more lanes may be designated as counterflow lanes, meaning that the direction of traffic in those lanes can be reversed at any time (see also reversible lane). Sometimes this is done as a way of managing rush hour traffic (one or more central lanes may flow inbound in the morning and outbound in the evening), in other cases the lanes are reversed only in unusual circumstances (such as a traffic accident or road construction closing one or more of the lanes).

However, Newberry Volcano has been transformed by tectonic processes, possibly related to subductive mechanisms that enhance melting of the Juan de Fuca tectonic plate. The High Lava Plains Trend, or the Newberry Trend, moves at an oblique angle to the underlying North American tectonic plate, for which subduction counterflow, gravitational flow along the lithosphere's base, faulting, and extension of the Basin and Range Province have all been proposed as possible mechanisms. At Newberry, the subducting plate has a depth that is shallower than elsewhere in the major crest of the Cascades, accounting for its unique magmas. Newberry Volcano is likely fed by a magma chamber under the large, cauldron-like caldera at its summit. This caldera has dimensions of and formed about 75,000 years ago.

Batch dryers are mainly used "On-Farm", particularly in the United States and Europe. They normally consist of a bin, with heated air flowing horizontally from an internal cylinder through an inner perforated metal sheet, then through an annular grain bed, some 0.50 m thick (coaxial with the internal cylinder) in radial direction, and finally across the outer perforated metal sheet, before being discharged to the atmosphere. The usual drying times range from 1 h to 4 h depending on how much water must be removed, type of grain, air temperature and the grain depth. In the United States, continuous counterflow dryers may be found on-farm, adapting a bin to slowly drying grain fed at the top and removed at the bottom of the bin by a sweeping auger.

The normally eastbound lanes of Dr. A. Santos Avenue from Soreena to Kabihasnan, eastbound lanes of NAIA Road from Quirino Avenue to Macapagal Boulevard, and southbound lanes of Macapagal Boulevard from NAIA Road to Bradco Avenue were also temporarily opened for counterflow in an effort to manage anticipated heavy traffic situation caused by the parade. Heavy rain disrupted the parade program causing delays with the floats stuck in mud at the starting point of the parade. Besides the float of the eight featured films of the MMFF, the parade was supposed to be joined by the floats of the Parañaque local government and Metropolitan Manila Development Authority but their vehicles were not reportedly present in the starting area. The float, featuring the film Fantastica, was the first float to leave the assembly area at 1:25 pm albeit without members of its cast.

This solution would be more suited to very narrow roads or ones with light traffic. Roadsign in Rennes indicating a street which is one-way for motorised vehicles but two-way for bicyclesIn Belgium since about 2005, and in France since 2010, the default position in towns has been for one-way streets to be available for cycling in either direction, known in French as sens unique limité (SUL) in Belgium and double sens cyclable (DSC) in France. In this case, a contraflow cycle lane is often marked in paint, with dotted white lines and ideograms of a bicycle, either all the way along the street if busy, or more commonly just at junctions. In the Netherlands, most one-way streets are two way for cyclists, although this is not always marked by a counterflow lane.

Starting from its western terminus at Chilco Street by the edge of Stanley Park, Georgia Street runs southeast, separating the West End from the Coal Harbour neighbourhood. It then runs through the Financial District; landmarks and major skyscrapers along the way include Living Shangri-La (the city's tallest building), Trump International Hotel and Tower, Royal Centre, 666 Burrard tower, Hotel Vancouver and upscale shops, the HSBC Canada Building, the Vancouver Art Gallery, Georgia Hotel, Four Seasons Hotel, Pacific Centre, the Granville Entertainment District, Scotia Tower, and the Canada Post headquarters. The eastern portion of West Georgia features the Theatre District (including Queen Elizabeth Theatre and the Centre in Vancouver for the Performing Arts), Library Square (the central branch of the Vancouver Public Library), Rogers Arena, and BC Place. West Georgia's centre lane between Pender Street and Stanley Park is used as a counterflow lane.

Tuna and other fast-swimming ocean-going fish maintain their muscles at higher temperatures than their environment for efficient locomotion. Tuna achieve muscle temperatures or even higher above the surroundings by having a counterflow system in which the metabolic heat produced by the muscles and present in the venous blood, pre-warms the arterial blood before it reaches the muscles. Other adaptations of tuna for speed include a streamlined, spindle-shaped body, fins designed to reduce drag, and muscles with a raised myoglobin content, which gives these a reddish colour and makes for a more efficient use of oxygen. In polar regions and in the deep ocean, where the temperature is a few degrees above freezing point, some large fish, such as the swordfish, marlin and tuna, have a heating mechanism which raises the temperature of the brain and eye, allowing them significantly better vision than their cold-blooded prey.

The 3He enters the cryostat at a pressure of a few hundred millibar. In the classic dilution refrigerator (known as a wet dilution refrigerator), the 3He is precooled and purified by liquid nitrogen at 77 K and a 4He bath at 4.2 K. Next, the 3He enters a vacuum chamber where it is further cooled to a temperature of 1.2–1.5 K by the 1 K bath, a vacuum-pumped 4He bath (as decreasing the pressure of the helium reservoir depresses its boiling point). The 1 K bath liquefies the 3He gas and removes the heat of condensation. The 3He then enters the main impedance, a capillary with a large flow resistance. It is cooled by the still (described below) to a temperature 500–700 mK. Subsequently, the 3He flows through a secondary impedance and one side of a set of counterflow heat exchangers where it is cooled by a cold flow of 3He. Finally, the pure 3He enters the mixing chamber, the coldest area of the device. In the mixing chamber, two phases of the 3He–4He mixture, the concentrated phase (practically 100% 3He) and the dilute phase (about 6.6% 3He and 93.4% 4He), are in equilibrium and separated by a phase boundary.
