Fill Down method

Copy method, the Cut method, the Fill Down method or the Sort method. For example,... 

The fourth method uses an array formula that can be entered into a single row of cells (here T5 U5) and then copied into the complete range of cells using either Fill Down or AutoFill ...

The Cone Resistance in the upper part of the fill (down to approximate 0.5 m below finished level) is not representative for the assessment of the relative density. Often a low resistance is measured as a consequence of surface failure due to insufficient overburden pressure. One should therefore be cautious when specifying a certain Cone Resistance for the upper part of the fill. Alternatively, for density testing nearer to the surface, the sand replacement or the rubber balloon method could be used (see Appendix B). 

If a Type I isotherm exhibits a nearly constant adsorption at high relative pressure, the micropore volume is given by the amount adsorbed (converted to a liquid volume) in the plateau region, since the mesopore volume and the external surface are both relatively small. In the more usual case where the Type I isotherm has a finite slope at high relative pressures, both the external area and the micropore volume can be evaluated by the a,-method provided that a standard isotherm on a suitable non-porous reference solid is available. Alternatively, the nonane pre-adsorption method may be used in appropriate cases to separate the processes of micropore filling and surface coverage. At present, however, there is no reliable procedure for the computation of micropore size distribution from a single isotherm but if the size extends down to micropores of molecular dimensions, adsorptive molecules of selected size can be employed as molecular probes. 

Estimatiofi of Niiroo-ot, Second Method.—Another method w hich dispenses with the small furnace and bicarbonate tube may also be used. The long combustion tube is closed at one end and magnesite m small lumps is introduced into the tube and shaken down to the closed end until there is a layer of about 13- 15 cm. (5—6 in.). This is kept in place by a plug of asbestos and the tube is filled s-uccessively with 5 cm. (2 in.) of coarse copper o.xide, then fine copper oxide mixed with the substance, a further layer of coarse copper oxide, and finally the... 

Slurry packing techniques are required for the preparation of efficient columns with rigid particles of less than 20 micrometers in diameter. The same general packing apparatus. Figure 4.8, can be used to pack columns by the balanced-density slurry, liquid slurry, or the viscous slurry techniques. Down-fill slurry packing is the method of choice for small bore columns and packed capillary columns. 

An extended line, sometimes called a dip leg or dip pipe, reduces the electrical charge that accumulates when liquid is allowed to free fall. When using dip pipes, however, care must be taken to prevent siphoning back when the inlet flow is stopped. A commonly used method is to place a hole in the dip pipe near the top of the vessel. Another technique is to use an angle iron instead of a pipe and to let the liquid flow down the angle iron (see Figure 7-21). These methods are also used when filling drums. 

As an approximate method for getting an idea about the size of capsule needed, a simple rule of six is very useful. Although not very accurate, the rule of six serves as an initial guide for the capsule size selection. When the bulk density of the powdered material is 0.6 g/cc, this rule helps in obtaining the capsule size which is fairly accurate. However, since the bulk density of pharmaceutical powders is different, it is always a good idea to verify the capsule size by actually filling the material. This rule will certainly narrow down the choice of capsule size selection for initial trials. The rule of six is given below ... 

The AVhy Tree provides a simple method for depicting the logical relationship between causes and effects of an incident.hs) The process starts hy displaying all direct losses and associated consequences in separate boxes. A drill down question that asks why challenges each box. Plausible explanations are entered into new boxes attached by straight lines to the subject or receptor box above. Ultimately, the page will fill up with several boxes attached by straight lines.
