Equation (3.79) was obtained by dividing the total mass of the system by the total number of moles (Af and Bg represent the initial number of moles of each one of the monomers). The factor xAfAf in the denominator represents the moles of type A functionalities that have reacted, which is equal to the number of moles that are lost by reaction provided that no intramolecular cycles are formed. As 1 mole of A reacts with 1 mole of B, it must be verified that... 

Chapter 13 provided an introduction to Sub procedures and Function procedures. By now it should be clear that a Sub procedure (a command macro) is a computer program that you "run" it can perform actions such as formatting, opening or closing documents, etc. A Function procedure (a user-defined fimction) is a computer program that calculates a value and returns it to the cell in which it is typed. A Function procedure cannot change the worksheet environment ( e.g., it can t make a cell Bold).

The only CAZy family with a unique protein fold is CBMl (CBD I), which is confined almost exclusively to fungal enzymes. CBM 1 modules, which are small (33 0 residues) all have a Type A function (although the converse is not true - other CAZy families and protein folds also have Type A function). The CBMl attached to the GH 7 catalytic domain of the cellobiohydrolase I of... 

All Type B function is associated with a p-sandwich fold, but not all p-sandwich folds are associated with Type B function. The p-sandwich fold is adopted by CAZy sequence Families 2, 3,4, 6, 9,11,15,17,22,27,28,29, 32, 34 and 36, but some CAZy Family 2 members (CBM 2a) and all CBM Family 3 members have Type A function. In CBM 2a and CBM 3, three aromatic residues are again disposed to make a planar hydrophobic face sheet, as with CBM 1, even though the overall fold is a p-sandwich. The multiplicity of binding functions that can be supported by the p-sandwich is emphasised from the structure of a CBM6 attached to a Clostridium thermocellum xylanase, which had two binding clefts, only one of which appeared to be used in xylan binding the apparently unused cleft in this structure was, however, the main binding site for a Family 22 and a Family 4 module. ... 

The same disposition of three planar hydrophobic aromatic residues is also adopted by CBM 5 and CBM 10, as other CBMs which have Type A function and unique protein folds. An NMR structure of the 60-residue CBM 5 of an Erwinia chrysanthemi endoglucanase revealed a ski-boot structure, with a flat hydrophobic face corresponding to the sole and heel of the ski-boot. This hydrophobic face contained the three planar hydrophobic residues (two tyrosines and a tryptophan).Also using a CBM 5, but as a chitin binding domain, is the chitinase B of Serratia marcescens (the catalytic domain being GH 18). ... 

Although one can have a broad picture of how Type A function comes about, the detailed kinetics and thermodynamics still present unsolved problems. The planar, hydrophobic, aromatic face presented by all the protein folds that have Type A function suggests that the driving force is hydrophobic and that therefore Type A CBDs should bind preferentially to hydrophobic faces of the polysaccharide crystal. Indeed, with gold-labelled CBM 1 and CBM 3 binding to cellulose lo, (triclinic) crystals of Valonia ventricosa, electron microscopy reveals just that - preferential binding to the (110) face of the crystal. 

However, the detailed kinetics and thermodynamics of Type A function present an as yet unsolved problem. With many CBMs, it is possible to obtain apparently conventional binding isotherms against various types of cellulose in the binding direction the cellulose does not bind more CBM if more is added and the amount of cellulose bound is constant with respect to time. However, if the solution is now diluted with buffer, no loss of CBM from the cellulose is seen, and if bound CBM is centrifuged off and placed in fresh buffer, no CBM is liberated the CBM binding is apparently irreversible.

A rigorous relation exists between the fugacity of a component in a vapor phase and the volumetric properties of that phase these properties are conveniently expressed in the form of an equation of state. There are two common types of equations of state one of these expresses the volume as a function of... 

Sample size is 100 ml and distillation conditions are specified according to the type of sample. Temperature and volume of condensate are taken simultaneously and the test results are calculated and reported as boiling temperature as a function of the volume recovered as shown in Table 2.1. 

Apolar stationary phases having no dipolar moments, that is their center of gravities of their positive and negative electric charges coincide. With this type of compound, the components elute as a function of their increasing boiiing points. The time difference between the moment of injection and the moment the component leaves the column is called the retention time. 

The first requirement is a source of infrared radiation that emits all frequencies of the spectral range being studied. This polychromatic beam is analyzed by a monochromator, formerly a system of prisms, today diffraction gratings. The movement of the monochromator causes the spectrum from the source to scan across an exit slit onto the detector. This kind of spectrometer in which the range of wavelengths is swept as a function of time and monochromator movement is called the dispersive type. 

This type of curve can be utilized for intermediate cuts between 250 and 400°C. They show the value of the property of a cut as a function of its initial point and its end point.

If a surface, typically a metal surface, is irradiated with a probe beam of photons, electrons, or ions (usually positive ions), one generally finds that photons, electrons, and ions are produced in various combinations. A particular method consists of using a particular type of probe beam and detecting a particular type of produced species. The method becomes a spectroscopic one if the intensity or efficiency of the phenomenon is studied as a function of the energy of the produced species at constant probe beam energy, or vice versa. Quite a few combinations are possible, as is evident from the listing in Table VIII-1, and only a few are considered here. 

Infrared and Raman spectroscopy each probe vibrational motion, but respond to a different manifestation of it. Infrared spectroscopy is sensitive to a change in the dipole moment as a function of the vibrational motion, whereas Raman spectroscopy probes the change in polarizability as the molecule undergoes vibrations. Resonance Raman spectroscopy also couples to excited electronic states, and can yield fiirtlier infomiation regarding the identity of the vibration. Raman and IR spectroscopy are often complementary, both in the type of systems tliat can be studied, as well as the infomiation obtained.

Gelemter and Rose [25] used machine learning techniques Chapter IX, Section 1.1 of the Handbook) to analyze the reaction center. Based on the functionalities attached to the reaction center, the method of conceptual clustering derived the features a reaction needed to possess for it to be assigned to a certain reaction type. A drawback of this approach was that it only used topological features, the functional groups at the reaction center, and its immediate environment, and did not consider the physicochemical effects which are so important for determining a reaction mechanism and thus a reaction type.
