Boring patterns

Chasmoendoliths and cryptoendoliths can affect the substrate by water retention. Their metabolic products are released into the microenvironment and may contribute to carbonate dissolution ( algues cariantes). True endoliths, or euendoliths, are those that penetrate actively into the interior of the substrate forming tunnels which follow specific boring patterns (Golubic, Friedmann and Schneider, unpublished results). 

Mechanical activity of boring organisms is also reflected in scratch marks (e.g. Warme, 1975). In general, boring patterns are determined both by the specificity of the boring organism as well as by the particular nature of the bored substrate, and both factors need to be considered in their interpretation (Golubic and Schneider, 1972). 

We shall discuss the importance and occurrence of the main representatives of the carbonate-removing organisms, their boring patterns, and means of carbonate removal. The contribution of various groups of organisms to carbonate bioerosion, with respect to destruction mechanisms, trace morphology, and habitat is summarized by Neumann (1968), Milliman (1974), Warme (1975), and Schneider (1976).

Liver disease is a major cause of all kinds of abnormal lipoproteins. In lipoprotein electrophoresis it often causes a boring pattern no alpha-lipoproteins and a very broad beta-band. The latter is due to a host of abnormal or abnormally composed lipoproteins. In summary, we find decreased alpha-lipoproteins, a dissociation of A-I and A-II (a rare instance of the presence of LP-A-II) decreased LP-B, abnormal VLDL, poor in Apo-C, remnants in the LDL-class, and LP-X. 

Concave surfaces are of industrial importance, in relation to the internal surface of bores, holes and pipes, but are not found on typical solid testpieces and have received much less discussion. The stress patterns will tend to be the opposite of those found on convex surfaces for example, an oxide growing by cation diffusion should be in tension at the metal interface. Bruce and Hancock have discussed the oxidation of curved surfaces and show how the time to adhesive failure of the oxide can be predicted if its mechanical properties are known. 

The repetition of sentence patterns is not only boring, but in some cases, it can reduce your grade. The SAT essay, for example, is scored by readers trained to look for, and reward, variety in sentence structure. They can deduct a point or two for an essay filled with sentences that follow the same pattern. When you re editing your essay, check for monotonous sentence structure. Here s an example ... 

There are newly retired people who contribute to the image of the passive, discarded, negative retiree. Upon retirement these folks become grouchy, defensive, unchanging, and unhappy. They often look bored, act bored, and are bored. They permit themselves to be pushed into old-fashioned retirement patterns because they refuse to seek new opportunities. They refuse to join the more dynamic retirees. 

The effect of concentration polarization on specific membrane processes is discussed in the individual application chapters. However, a brief comparison of the magnitude of concentration polarization is given in Table 4.1 for processes involving liquid feed solutions. The key simplifying assumption is that the boundary layer thickness is 20 p.m for all processes. This boundary layer thickness is typical of values calculated for separation of solutions with spiral-wound modules in reverse osmosis, pervaporation, and ultrafiltration. Tubular, plate-and-ffame, and bore-side feed hollow fiber modules, because of their better flow velocities, generally have lower calculated boundary layer thicknesses. Hollow fiber modules with shell-side feed generally have larger calculated boundary layer thicknesses because of their poor fluid flow patterns. 

We use sampling grids mainly for surface soil sampling, however, it is not unusual to place soil borings and collect subsurface samples on a grid pattern. Grids are also used for soil sampling from the bottom and sidewalls of excavation pits and trenches. 

In 7000 BC, around the area today called Denmark, man already knew how to cut and polish amber. Using a piece of bone or a stone he could chip it into shape, and polish it up with a bit of leather or fiir. He made talismans, engraved simple patterns on them and bored a hole at one end so that they could be worn on a string of some sort. 

Two distinct procedures may be used. The preferred method is to use a large thread cutting lathe, or a lathe and V x28 EF (Extra Fine)Die to turn down and thread muzzle to specs given in fig.3. This will duplicate the Colt M-16/AR-15 and Armalite AR 18/AR 180 muzzle dimensions. The %x28 pattern will allow installation of the Sionics Suppressors and other accessories available for the above guns. Maximum allowable misalignment of threads to bore axis 1 so it may prove a wise move to farm out the job to a competent machin-ist/gunsmith. No need to mention the suppressor, you only want to mount an M-16 flash hider. 

The wear pattern on punch heads, punch tips, and in die bores may indicate specific problems during tableting. Measuring dimensions of punches and dies is a task which has to be performed frequently and can be carried out computer-aided. Dimensions to be checked are overall length, cup depth, working length, diameters, tip diameter, and die bore dimensions. Use a micrometer.
