a viewing cone can be defined starting from a certain application and the related geometry of observation, from which a range of directions can be obtained that specify the viewing cone required for that task. inside this viewing cone certain physical parameters that are related to the visual performance of the display device must remain within .
a cross section of a polyhedron is a polygon.. the conic sections – circles, ellipses, parabolas, and hyperbolas – are plane sections of a cone with the cutting planes at various different angles, as seen in the diagram at left.. any cross-section passing through the center of an ellipsoid forms an elliptic region, while the corresponding plane sections are ellipses on its surface.
a shallow foundation is a type of building foundation that transfers building loads to the earth very near to the surface, rather than to a subsurface layer or a range of depths as does a deep foundation.shallow foundations include spread footing foundations, mat-slab foundations, slab-on-grade foundations, pad foundations, rubble trench foundations and earthbag foundations.

harpoon reactions are a type of chemical reaction between two substances: one generally a metal prone to form a cation, and the other generally a halogen prone to form an anion.. their main feature is that these reactions, unlike most reactions, have steric factors greater than unity, that is, they take place faster than predicted by collision theory.
in a nozzle or other constriction, the discharge coefficient also known as coefficient of discharge or efflux coefficient is the ratio of the actual discharge to the theoretical discharge, i.e., the ratio of the mass flow rate at the discharge end of the nozzle to that of an ideal nozzle which expands an identical working fluid from the same initial conditions to the same exit pressures.
the absorption cross section for thermal neutrons is 0.18 barn for zirconium, which is much lower than that for such common metals as iron 2.4 barn and nickel 4.5 barn . the composition and the main applications of common reactor-grade alloys are summarized below. these alloys contain less than 0.3% of iron and chromium and 0.1–0.14% oxygen.

a section, or cross-section, is a view of a 3-dimensional object from the position of a plane through the object. a section is a common method of depicting the internal arrangement of a 3-dimensional object in two dimensions. it is often used in technical ding and is traditionally crosshatched. the style of crosshatching often indicates the .
eviews can be used for general statistical analysis and econometric analyses, such as cross-section and panel data analysis and time series estimation and forecasting. eviews combines spreadsheet and relational database technology with the traditional tasks found in statistical software, and uses a windows gui.
the molar attenuation coefficient is a measurement of how strongly a chemical species attenuates light at a given wavelength. it is an intrinsic property of the species. the si unit of molar attenuation coefficient is the square metre per mole m 2 /mol , but in practice, it is usually taken as the m −1 ⋅cm −1 or the l⋅mol −1 ⋅cm −1.
the neutron cross section is defined for a given type of target particle. for example, the capture cross section of hydrogen -2 referred to as deuterium is much smaller than that of common hydrogen-1. this is the reason why some reactors use heavy water in which most of the hydrogen is deuterium instead of ordinary light water as moderator .
in electronics, a cross section, cross-section, or microsection, is a prepared electronics sample that allows analysis at a plane that cuts through the sample.it is a destructive technique requiring that a portion of the sample be cut or ground away to expose the internal plane for analysis. they are commonly prepared for research, manufacturing quality assurance, supplier conformity, and .
cross-sectional data, or a cross section of a study population, in statistics and econometrics is a type of data collected by observing many subjects such as individuals, firms, countries, or regions at the one point or period of time. the analysis might also have no regard to differences in time.
derivation of kantrowitz limit. assume a fluid enters an internally contracting nozzle at cross-section 0, and passes through a throat of smaller area at cross-section 4. a normal shock is assumed to start at the beginning of the nozzle contraction, and this point in the nozzle is referred to as cross-section 2. due to conservation of mass .
why are the colours faded on the cross-section part? i don't find it enhances the image. why is the marrow red? and why does the marrow stop where it does, and so sharply? marrow in the shaft of long bones is typically yellow, with red marrow in the head through the cancellous bone. would it be a good thing to show the epiphyseal plate?
the clitoral crura singular: clitoral crus are two erectile tissue structures, which together form a v-shape. crus is a latin word that means 'leg'. each 'leg' of the v converges on the clitoral body. at each divergent point is a corpus cavernosum of clitoris. the crura are attached to the pubic arch, and are adjacent to the vestibular bulbs .
