Drilling Formula Sheets is a set of Drilling Formulas used commonly by drilling engineers in the onshore and offshore oil drilling industry. They are used as part of a key piece of engineering work called Well Control .
A digital terrain model (DTM) represents specifically the ground surface while DEM and DSM may represent tree top canopy or building roofs. While a DSM may be useful for landscape modeling , city modeling and visualization applications, a DTM is often required for flood or drainage modeling, land-use studies , [ 1 ] geological applications, and ...

Triangulated irregular network TIN overlaid with contour lines. In computer graphics, a triangulated irregular network (TIN) [1] is a representation of a continuous surface consisting entirely of triangular facets (a triangle mesh), used mainly as Discrete Global Grid in primary elevation modeling.
Free base DMT extracted from Mimosa hostilis root bark (left); vape cartridge made with freebase DMT extract (right) A standard dose for vaporized DMT is 20–60 milligrams, depending highly on the efficiency of vaporization as well as body weight and personal variation.
The plus–minus method, also known as CRM (conventional reciprocal method), is a geophysical method to analyze seismic refraction data developed by J. G. Hagedoorn.It can be used to calculate the depth and velocity variations of an undulating layer boundary for slope angles less than ~10°.
This article presents a set of useful conversions and formulas for air dispersion modeling of atmospheric pollutants and for complying with the various regulations as to how to express the concentrations obtained by such modeling.
This is an alphabetically sorted list of all mental disorders in the DSM-IV and DSM-IV-TR, along with their ICD-9-CM codes, where applicable. The DSM-IV-TR is a text revision of the DSM-IV. [ 1 ] While no new disorders were added in this version, 11 subtypes were added and 8 were removed.
