The procedure whereby a Iktle alcohol is rapidly added to the vessel, supported in the funae chamber and containing some concentrated nitric acid, although generally preceded by a short period of induction, may be extremely dangerous and should not be used. Under no circumstances should concentrated nitric acid be euided to ethyl alcohol—a violent explosion may result. [Pg.54]

Specifications. Among the many specifications covering refractory products, the best known are those pubUshed by ASTM. In addition, specifications are issued by the U.S. Government and the armed forces. The former are generally preceded by the prefix HH and the later by the prefix MIL. The ASTM refractory specifications always suggest a use, whereas federal and military specifications are iaconsistent ia this respect. [Pg.35]

The crosslinking of resoles is slightly more straightforward than that of novolaks, if only because there are fewer possible chemical structures involved in the setting reaction or finished structure. Since resoles are prepared under alkaline conditions, crosslinking is generally preceded by neutralisation. This enhances the ease with which network structures can form when the resin is simply heated. [Pg.57]

Protein (as pure as possible) is specifically cleaved with a protease under defined conditions. Thus the mixture of peptides, specific for the given protein, is produced. In classical proteomic approach this step is generally preceded by separation of individual proteins, usually by two-dimensional electrophoresis. [Pg.170]

Diafiltration is a process whereby an ultrafiltration system is utilized to reduce or eliminate low molecular mass molecules from a solution and is sometimes employed as part of biopharmaceuti-cal downstream processing. In practice, this normally entails the removal of, for example, salts, ethanol and other solvents, buffer components, amino acids, peptides, added protein stabilizers or other molecules from a protein solution. Diafiltration is generally preceded by an ultrafiltration step to reduce process volumes initially. The actual diafiltration process is identical to that of ultrafiltration, except for the fact that the level of reservoir is maintained at a constant volume. This is achieved by the continual addition of solvent lacking the low molecular mass molecules that are to be removed. By recycling the concentrated material and adding sufficient fresh solvent to the system such that five times the original volume has emerged from the system as permeate, over 99... [Pg.139]

If the reaction lasts more than a day, a period of deep sleep generally precedes full recovery. Return of appetite, interest in recreation and a normal display of enthusiasm and spontaneity in conversation are reliable indications that the delirium is over... ... [Pg.47]

Crystallization is generally preceded by two types of nucleation. The primary nucleation occurs with the formation of clusters of molecules at the submicron level. When the concentration exceeds saturation to afford supersaturation, the clusters become nuclei. The secondary nucleation is caused by particles due to primary nucleation or seeds. There are many strategies to achieve supersaturation to initiate crystallization such as cooling, evaporation, and antisolvent addition. [Pg.249]

Animal studies have shown that oral exposure to FireMaster PBB causes a wasting syndrome characterized by progressive decreased weight gain, with immediate moderate to severe body weight loss generally preceding death." ... [Pg.592]

Rarely, a grand mal seizure occurs, generally preceded by weakness, dizziness, and headache,... [Pg.53]

Studies to date have shown that increases in gene transcription rates generally precede flavonoid production. This observation, in conjunction with studies on flavonoid-related transcription factors (TFs), suggests that gene transcription is the key point for biosynthetic gene regulation, rather than translation or post-translational steps. Post-transcriptional regulation has been reported for flavonoid biosynthesis (reviewed in Ref. 14 and recently... [Pg.182]

The MAPK/ERK proteins are at the lower end of signal transduction within a MAPK module and are generally preceded by two other protein kinases (Fig. 10.2). The MAPK/ERK proteins receive the signal in the form of an activating phosphorylation by a preceding protein kinase known as MAP/ERK kinase (MEK) or also MAP kinase kinase (MAPKK). [Pg.352]

The rest of the name, which generally precedes the parent name, describes the substituent and its position on the parent chain. In our example, 3-methoxy means a CH30— group at C3. Thus the complete structure of 3-methoxybutanal is... [Pg.187]

The design of libraries is generally preceded by the selection of some rational catalyst concept, yet may include some degree of serendipity. Library Studio [31] served as the principal library design tool. To design a thin film library, the substrate or destination for the materials array is selected, in this case an 8x8 electrode array, as described above. The set of chemical sources (e.g., metals or metal... [Pg.275]

In addition, the selection and design of the atomizer system is of great importance to product properties. In fact, all the variables noted above interact so that changes in product diameter can be expected to be accompanied by changes in other properties as well. Small-scale experimental tests must generally precede final design. [Pg.144]

Some applications of biomarkers are outlined in Table 17.4. Many, but not all, biomarker applications are part of the drug development process that was diagrammed in Chapter 1 (Figure 1.1). Studies to provide an epidemiologic and pathophysiologic basis for biomarkers have been alluded to already, and these generally precede their use in... [Pg.279]
