Studies show that below 15 °C (59 °F), the caterpillars are unable to process the food in their guts. Early instars are black and their bodies readily absorb heat. When basking, they typically pack together tightly, reducing heat loss due to convective currents. Their long setae also serve to stem convective heat loss.

A helix hairpin, also known as an alpha-alpha hairpin, is composed of two antiparallel alpha helices connected by a loop of two or more residues. True to its name, it resembles a hairpin. A longer loop has a greater number of possible conformations. If short strands connect the helices, then the individual helices will pack together through their hydrophobic residues.

Thus, the Bell Jet Flying Belt remained an experimental model. On 29 May 1969, Wendell Moore died of complications from a heart attack he had suffered six months earlier, and work on the turbojet pack was ended. Bell sold the sole version of the "Bell pack", together with the patents and technical documentation, to Williams Research Corporation. This pack is now in the Williams International company museum.

Elephants appear to use seismics for a number of purposes. An individual running or mock charging can create seismic signals that can be heard at great distances. When detecting the seismics of an alarm call signalling danger from predators, elephants enter a defensive posture and family groups will pack together. Seismic waveforms produced by locomotion appear to travel distances of up to while those from vocalisations travel .

The experimentally determined consolidation curve (blue dots) for a saturated clay showing a procedure for computing the preconsolidation stress. Consolidation is the process in which reduction in volume takes place by the gradual expulsion or absorption of water under long-term static loads. When stress is applied to a soil, it causes the soil particles to pack together more tightly. When this occurs in a soil that is saturated with water, water will be squeezed out of the soil.

His father, George Pack, Jr. had established two sawmills outside of Lexington, Michigan, in a place known as Pack's Mills. After years of working with the elder Pack, in 1860 George Willis Pack, together with John L. Woods, established Carrington, Pack & Company, in Sand Beach, Michigan. In 1864, with Woods and Jeremiah Jenks, George Willis Pack established a second sawmill, Pack, Jenks & Company, also near Sand Beach. A third firm, Woods & Company, in Port Crescent, Michigan, was formed in 1870.

The basic jelly roll structure consists of eight beta strands arranged in two four-stranded antiparallel beta sheets which pack together across a hydrophobic interface. The strands are traditionally labeled B through H for the historical reason that the first solved structure, of a jelly roll capsid protein from the tomato bushy stunt virus, had an additional strand A outside the fold's common core. The sheets are composed of strands BIDG and CHEF, folded such that strand B packs opposite strand C, I opposite H, etc.

The eight helices of the globin fold core share significant nonlocal structure, unlike other structural motifs in which amino acids close to each other in primary sequence are also close in space. The helices pack together at an average angle of about 50 degrees, significantly steeper than other helical packings such as the helix bundle. The exact angle of helix packing depends on the sequence of the protein, because packing is mediated by the sterics and hydrophobic interactions of the amino acid side chains near the helix interfaces.

In statistical mechanics, configuration entropy is the portion of a system's entropy that is related to discrete representative positions of its constituent particles. For example, it may refer to the number of ways that atoms or molecules pack together in a mixture, alloy or glass, the number of conformations of a molecule, or the number of spin configurations in a magnet. The name might suggest that it relates to all possible configurations or particle positions of a system, excluding the entropy of their velocity or momentum, but that usage rarely occurs.

Crystal structure of c-Fos:c-Jun heterodimer and DNA complex (). In the "Leucine zipper" domain (gray), the hydrophobic residues on c-Fos and hydrophobic residues on c-Jun pack together on the interface of the coiled- coil (leucines are colored in blue, and the other hydrophobic residues are colored in yellow). Residues from the "basic region" (purple) directly interact with the DNA (red). Activator protein 1 (AP-1) is a transcription factor that regulates gene expression in response to a variety of stimuli, including cytokines, growth factors, stress, and bacterial and viral infections.

Lord Clifden was settled at the rear of the field by jockey Tom Chaloner. Both La Toucques and Lord Clifden made progress through the pack together and when the field turned into the finishing straight the pair were vying for the lead along with The Ranger and Saccharometer. However, Lord Clifden was the first one to fade and the finish was fought out between La Toucques and The Ranger. The Ranger won the race by one length from La Toucques, who was two lengths in front of Saccharometer.

The mostly linear molecules pack together well, so intermolecular forces are stronger than in highly branched polymers. HDPE can be produced by chromium/silica catalysts, Ziegler–Natta catalysts or metallocene catalysts; by choosing catalysts and reaction conditions, the small amount of branching that does occur can be controlled. These catalysts prefer the formation of free radicals at the ends of the growing polyethylene molecules. They cause new ethylene monomers to add to the ends of the molecules, rather than along the middle, causing the growth of a linear chain.

Traditional methods of buckypaper production involves the use of surfactants to disperse carbon nanotubes into aqueous solutions. It was found that filtering this suspension allowed the nanotubes to pack together in a paper-like mat, thus coining the term "buckypaper" (bucky being the reference to the buckminsterfullerene molecule). The problem was the difficulty in removing the surfactant afterwards, where the surfactant has been linked with cell lysis and tissue inflammation. Acid oxidation of carbon nanotubes can also be used in filtration to form buckypaper, but requires a high degree of surface acidic groups in order to obtain efficient dispersal in aqueous solution.

L27_2 domain-mediated protein assemblies have been shown to play essential roles in cellular processes including asymmetric cell division, establishment and maintenance of cell polarity, and clustering of receptors and ion channels. Members of this family form specific heterotetrameric complexes, in which each domain contains three alpha-helices. The two N-terminal helices of each L27_2 domain pack together to form a tight, four- helix bundle in the heterodimer, whilst the third helix of each L27_2 domain forms another four-helix bundle that assembles the two units of the heterodimer into a tetramer. The L27_N domain is often found at the N-terminus of the L27 domain.

Sinatra as Tony Rome Due to an obligation he owed to 20th Century Fox for walking off the set of Henry King's Carousel (1956), Sinatra starred opposite Shirley MacLaine, Maurice Chevalier and Louis Jourdan in Can-Can (1960). He earned $200,000 and 25% of the profits for the performance. Around the same time, he starred in the Las Vegas-set Ocean's 11 (also 1960), the first film to feature the Rat Pack together and the start of a "new era of screen cool" for Santopietro. Sinatra personally financed the film, and paid Martin and Davis Jr. fees of $150,000 and $125,000 respectively, sums considered exorbitant for the period.

The course first started as a holiday music camp at Hartbeespoort Dam in 1964, with 87 participants, organised by the South African Society of Music Teachers (SASMT). The early pioneers included Korie Koornhof, Arthur Wegelin, Paul Loeb van Zuilenburg, Diane Heller and Betty Pack together with the first conductor, Leo Quayle. The seeds those early pioneers sowed quickly took root and in 1975 the SA National Youth Orchestra took part in the International Festival of Youth Orchestras in Aberdeen, followed by a short tour of Europe three years later. In 1979, Sasol came on board as a founding partner of the National Youth Orchestra Foundation to provide infrastructure and organisational skills.

With 3 U-boats destroyed for no ships lost ON 207 was undoubtedly an Allied victory; but if Admiralty was hoping to inflict a crushing blow to UbW by wiping out an entire wolf pack, this success eluded them. Most of the U-boats were unable to make contact, and those that did were unable to shadow effectively in order to bring the pack together. Possibly the escorts were unfamiliar with their role as bait, and were too efficient at keeping the pack away from the convoy. Following ON 207 BdU re-configured Siegfried to form 3 sub-groups to cover a wider area, but this failed to produce results.

The patent does not specify any crystal forms of the compounds or discuss their relative advantages and disadvantages.US Patent 5,521,184EP0564409 On 18 July 1997, Novartis filed a new patent application in Switzerland on the beta crystalline form of imatinib mesylate (the mesylate salt of imatinib). The "beta crystalline form" of the molecule is a specific polymorph of imatinib mesylate; a specific way that the individual molecules pack together to form a solid. This is the actual form of the drug sold as Gleevec/Glivec; a salt (imatinib mesylate) as opposed to a free base, and the beta crystalline form as opposed to the alpha or other form.Staff, European Medicines Agency, 2004.

Sawdust, flour, or chalk are usually used to mark the trail. The trail periodically ends at a "check," The pack must find where it begins again; often, the trail includes false trails, short cuts, dead ends, check backs, and splits. These features are designed to keep the pack together despite differences in fitness level or running speed, as front-runners are forced to slow down to find the "true" trail, allowing stragglers to catch up. Members sometimes describe their group as "a drinking club with a running problem," indicating that the social element of an event is as important, if not more so than any athleticism involved.

Coiled-coil α helices are highly stable forms in which two or more helices wrap around each other in a "supercoil" structure. Coiled coils contain a highly characteristic sequence motif known as a heptad repeat, in which the motif repeats itself every seven residues along the sequence (amino acid residues, not DNA base-pairs). The first and especially the fourth residues (known as the a and d positions) are almost always hydrophobic; the fourth residue is typically leucine this gives rise to the name of the structural motif called a leucine zipper, which is a type of coiled-coil. These hydrophobic residues pack together in the interior of the helix bundle.

Using an optical telegraph signalling system, the fort could communicate with the Fort of Archeira to the south of Torres Vedras and from there to both the Fort of São Vicente to the north of the same town and the Atlantic coast. Part of the original road used to supply the fort The Fort of Alqueidão had a garrison of 1,590 men, and was equipped with 24 cannon, believed to be 14 12-pounder artillery, six 9-pouders, and four 6-pounders. The troops were Portuguese, under the command of the British Brigadier-General Denis Pack, together with two artillery companies from Sobral formed and trained by William Beresford who was both a general in the British army and a marshal of the Portuguese army.

The scutoid explains how epithelial cells (the cells that line and protect organs such as the skin) efficiently pack in three dimensions. As epithelial tissue bends or grows, the cells have to take on new shapes to pack together using the least amount of energy possible, and until the scutoid's discovery, it was assumed that epithelial cells packed in mostly frustums, as well as other prism-like shapes. Now, with the knowledge of how epithelial cells pack, it opens up many new possibilities in terms of artificial organs. The scutoid may be applied to making better artificial organs, allowing for things like effective organ replacements, recognizing if a person's cells are packing correctly or not, and ways to fix that problem.
