IDA Indoor Climate and Energy (ICE) is a new generation of building performance simulation tools. The mathematical models are described in terms of equations in a formal language, NMF. Whenever appropriate, models recommended by ASHRAE have been used. Advanced database features support model reuse. 

As Fig. 16 shows, the preferential binding of DMSO, DMF and NMF from aqueous solution to (Lys HBr)n at low contents of the organic solvent x increases with its concentration. However, at approximately x3 = 0,2 a maximum is reached and then preferential hydration between x3 = 0,3 and 0,5 occurs. No preferential binding was observed for NMP, EG or 2 PrOH, however increasing hydration occured with x3. Only in 2 PrOH at x3 > 0,3 a-helix formation occured. Furthermore binding parameters for the systems NMP + DMSO, EG + DMSO and DMF + DMSO have been determined. An initial preferential binding of DMSO by (Lys HBr)n, a maximum and a subsequently inversion of the binding parameter was also observed in these mixtures. The order of relative affinity is DMSO > DMF > EG > NMP. In DMF/DMSO-mixtures (Lys HBr) attains an a-helical conformation above 20 vol.- % DMF and in 2-PrOH/water above 70 vol.- % 2 Pr-OH.

In HDPE and LDPE matrices, the introduction of PMF with polyethylene coats affects the viscosity in such a way that is independent of the nature and particle size distribution of the mineral filler employed and depends only on NMF particle size. All other conditions identical, this effect is the same as that of the particles of standard high-molecular PE [164, 297, 298].

The Hg/V-methylformamide (NMF) interface has been studied by the capacitance method as a function of temperature.108,294,303 The potential of Hg was measured with respect to the reference electrode Ag/0.05 M AgC104 + 0.05 M NaC104 in water. The specific adsorption of C104 was found to be negligible at a < 6 /iC cm"2. The experimental capacitance data have been discussed in terms of the four-state model,121,291,294 which assumes the presence of both monomers and clusters in the surface layer of the solvent. The model has been found to describe the experimental picture qualitatively but not quantitatively. This is related to the fact that NMF is a strongly associated solvent.108,109,294,303... 

The Hg/NMF interface has been studied more recently also by Amokrane and Badiali122 on the basis of their new theoretical approach to capacitances. 

The entropy of formation of the interface was calculated from the temperature coefficient of the interfacial tension.304 The entropy of formation has been found to increase with the nature of the electrolyte in the same sequence as the single cation entropy in DMSO.108, 09,329 The entropy of formation showed a maximum at negative charges. The difference in AS between the maximum and the value at ff=ocan be taken as a measure of the specific ordering of the solvent at the electrode/solution interface. Data 108,109304314 have shown that A(AS) decreases in the sequence NMF > DMSO > DMF > H90 > PC > MeOH. 

Studies of pzc in mixed solvents were also carried out by Blaszczyk etal n using the dipping method. They worked in mixtures offormamide and NMF and estimated the shift of the standard potential of the hydrogen electrode, of the surface dipole potential atHg, and of the liquid junction potential. 

Theoretical C,E and C, a curves have been compared with experimental capacitance curves.359 In a wide range of potentials, the coincidence was good and it was concluded that the GCSG model is acceptable for Ga, In(Ga), Tl(Ga), and Hg electrodes in NMF + NaC104 solution. 

Results in other solvents are scanty for metals other than Hg. Liquid Ga and its T1 and In liquid alloys have been studied in DMSO, DMF, NMF, AN,343,894 MeOH360 andEtOH.361 Among solid metals, only Bi,28,152 Au,25,26,109 Al,750,751 and Fe729 have been investigated in a number of nonaqueous solvents. Pt and Pd have been studied in DMSO and... 

The same group found that heteroaromatic halides can be smoothly phenylated using NaBPh4 as the transmetallating agent and ligand-free Pd(OAc)2 as a catalyst with water or AT-methylformamide (NMF) as the solvent (Scheme 21) [39], The experiments were all performed using power control.

FeMoco can be extracted from the MoFe protein into A(-methylfor-mamide (NMF) solution 32) and has been analyzed extensively using a wide range of spectroscopic techniques both bound to the protein and in solution after extraction from it (33). The extracted FeMoco can be combined with the MoFe protein polypeptides, isolated from strains unable to synthesize the cofactor, to generate active protein. The structure of the FeMoco is now agreed 4, 5, 7) as MoFeTSg homocitrate as in Fig. 4. FeMoco is bound to the a subunit through residues Cys 275, to the terminal tetrahedral iron atom, and His 442 to the molybdenum atom (residue numbers refer to A. vinelandii). A number of other residues in its environment are hydrogen bonded to FeMoco and are essential to its activity (see Section V,E,2). The metal...
