Webster County lies along the south line of Nebraska. Its south boundary line abuts the north boundary line of the state of Kansas. The terrain of Webster County consists of low rolling hills, sloping to the east. The more planar areas of the county are used for agriculture, mostly under center pivot irrigation.

Cycloalkanes have similar properties to alkanes but have higher boiling points. The aromatic hydrocarbons are unsaturated hydrocarbons which have one or more planar six-carbon rings called benzene rings, to which hydrogen atoms are attached with the formula CnH2n-6. They tend to burn with a sooty flame, and many have a sweet aroma. Some are carcinogenic.

Western façade Several historians have noted the originality of the western façade, in that it is much more planar than usual in French Gothic architecture. It is in effect a screen, 28.6 metres high by 19.5 m wide and 6.2 m deep. There are three levels. The lowest has three large arcades forming the entry into a porch whose vaults are supported by two rows of pillars.

In slopes with coarse-grained soil or rocks, falls typically occur as the rapid descent of rocks and other loose slope material. A slope topples when a large column of soil tilts over its vertical axis at failure. Typical slope stability analysis considers sliding failures, categorized mainly as rotational slides or translational slides. As implied by the name, rotational slides fail along a generally curved surface, while translational slides fail along a more planar surface.

Aromaticity of the arsole manifests itself in delocalization and resonance of its ring electrons. It is closely related to planarity in that the more planar the molecule the stronger its aromaticity. Aromaticity of arsole and its derivatives has been debated for years both from experimental and theoretical point of view. A 2005 review combined with quantum chemical calculations concluded that arsole itself is "moderately" aromatic as its ring current is 40% that of pyrrole, which is known to be aromatic.

These methods in turn can be subdivided into template and pocket based methods. Template based methods search for 3D similarities between the target protein and proteins with known binding sites. The pocket based methods search for concave surfaces or buried pockets in the target protein that possess features such as hydrophobicity and hydrogen bonding capacity that would allow them to bind ligands with high affinity. Even though the term pocket is used here, similar methods can be used to predict binding sites used in protein-protein interactions that are usually more planar, not in pockets.

Beneath southern IBM, found a DSZ lying 80 km and 120 km deep, with the two zones separated by 30 35 km. Earthquake focal mechanisms indicate that the upper zone, where most events occur, is in downdip compression, while the lower zone is in downdip extension. This DSZ is located at a depth where the curvature of slab is greatest; at greater depths it unbends into a more planar donfiguration. suggested that unbending or thermal stresses in the upper 150 km of the slab may the primary cause of the seismicity.

With Walter Quirt and James Guy, he was a prominent exponent of "social surrealism". After the war, his painting became more planar and abstract, with elements of cubism, and he disavowed the personal sadness in his earlier works in favor of expressing the "exuberance and organic means of life itself". The New York Times also attributed his decline to his being "a relentless borrower, an irrepressible eclectic who seemed to prey voraciously on the styles of others". Born in Cairo, Egypt, as a child he lived in Milan and Geneva while his Italian father, a professional violinist, toured the world.

APG is produced in a process similar method to Highly Oriented Pyrolytic Graphite (HOPG), where hydrocarbon gas is heated until it breaks down into carbon. Pyrolytic graphite (PG) is then grown on plates using a chemical vapor deposition (CVD) process. The PG is then annealed at high temperature to form the more planar and more uniform carbon structure of APG, described above. The primary difference between the HOPG and APG synthesis methods is that the APG annealing process does not require the use of induced stresses, resulting in a more affordable and practical bulk material for production use.

The Y145A and H148D mutations in Cerulean stabilize these interactions and allow the chromophore to be more planar, better packed, and less prone to collisional quenching. Additional site-directed random mutagenesis in combination with fluorescence lifetime based screening has further stabilized the seventh β-strand resulting in a bright variant, mTurquoise2, with a quantum yield (QY) of 0.93. The red-shifted wavelength of the YFP derivatives is accomplished by the T203Y mutation and is due to π-electron stacking interactions between the substituted tyrosine residue and the chromophore. These two classes of spectral variants are often employed for Förster resonance energy transfer (FRET) experiments.

Perhaps the most significant innovation at this time derived from the ideas of Naum Gabo, who was interested in the principle of stereometry - defining forms in terms of space rather than mass. Barns-Graham's series of glacier pictures that started in 1949, inspired by her walks on the Grindelwald Glacier in Switzerland, reflect the idea of looking at things in a total view, not only from the outside but from all points, including inside. In 1952 her studies of local forms became more planar and two dimensional, but from the mid-1950s she had developed a more expressionist and free form attitude following journeys to Spain. In the early 1960s, reflecting the turmoil in her personal life, Barns-Graham adopted a severe geometrical form of abstraction as a way of taking a fresh approach to her painting.

Thickness is closely related to the problem of simultaneous embedding.. If two or more planar graphs all share the same vertex set, then it is possible to embed all these graphs in the plane, with the edges drawn as curves, so that each vertex has the same position in all the different drawings. However, it may not be possible to construct such a drawing while keeping the edges drawn as straight line segments. A different graph invariant, the rectilinear thickness or geometric thickness of a graph , counts the smallest number of planar graphs into which can be decomposed subject to the restriction that all of these graphs can be drawn simultaneously with straight edges. The book thickness adds an additional restriction, that all of the vertices be drawn in convex position, forming a circular layout of the graph.

The observed geometry reflects a compromise between two competing factors: 1) stabilization of the N lone pair in an orbital with significant s character favors pyramidalization (orbitals with s character are lower in energy), while 2) delocalization of the N lone pair into the aryl ring favors planarity (a lone pair in a pure p orbital gives the best overlap with the orbitals of the benzene ring π system). Consistent with these factors, substituted anilines with electron donating groups are more pyramidalized, while those with electron withdrawing groups are more planar. In the parent aniline, the lone pair is approximately 12% s character, corresponding to sp7.3 hybridization. (For comparison, alkylamines generally have lone pairs in orbitals that are close to sp3.) The pyramidalization angle between the C–N bond and the bisector of the H–N–H angle is 142.5°.
