Casing string types

CASING AND CASING STRING DESIGN Types of Casing... 

Based upon the primary function of the casing string, there are five types of casing to be distinguished. 

Casing must be designed to resist expected burst pressure at any depth. In burst pressure consideration, it is suggested to consider different design models depending upon the type of casing string. 

The address can be entered either as text, or by highlighting the cell involved with the mouse pointer. In the latter case it may be shown in the message box in so-called row-column notation, as in R3C7 for row3 column 7, i.e., G3. Note that Type = 0 will read a formula, Type = 1 a number, Type = 2 a text string, Type = 4 will yield a logical value (True when the address contains a number, False when it is empty or contains a zero), Type = 8 will read a cell reference as a Range, and Type = 64 will read an array.

In the case of the crystalline silicates an approach which takes account of the partly covalent character of the Si-O bond is helpful. The [SiCL]4- tetrahedron is taken as a basic building unit, and in most of the silicates these tetrahedra are linked together in an ordered fashion to form strings as in diopside (MgCa(Si03)2), sheet structures as in clay minerals, or three-dimensional frameworks as in quartz and the feldspars. Within these frameworks isomorphic replacement of one cation type for another is extensive. For example, the replacement of Si4+ by Al3+ is common, with the necessary lattice charge balance being maintained either by the incorporation of interstitial cations such as Na+... 

Case 2 includes a total of 12 batteries arranged in an array of three parallel strings of four batteries each. A similar type of battery has been used in this simulation, however in this case each parallel string has a capacity of 635 Ah. With 1905 Ah total storage capacity, the battery array has the ability to solely power the load for 1.25 days, based on 58 kWh daily consumption. 

Schemas are a newer development on the XML landscape. Like a DTD, a schema supplies the rules for building a document and indicates what tags may be used, what their attributes are, and how they relate to one another. Unlike a DTD, however, a schema has an additional level of specificity in that it can define data types. For example, a DTD might have a tag designated as , the content of which might be either numerical or a character string. A schema, by contrast, could ensure that the value entered was a number. This is clearly an appealing feature for the pharmaceutical industry, especially in the case of information exchange between databases or other applications making use of rigidly defined data types.

In mollusks, sexes are separate. Bivalves release their eggs and sperm into the water, and fertilization occurs there. In other types of mollusks, internal fertilization, a process in which sperm are transferred to the body of the female, is the norm. Following internal fertilization, females deposit strings or cases of eggs on the sand, seaweed, or rocks. In both internal and external fertilization, zygotes develop into swimming larvae that metamorphose into adult forms.
