A scheme for a ground fault protection will depend upon the type of system and its grounding conditions, i.e. whether the system is three-phase three-wire or three-phase four-wire. A three-wire system will require an artificial grounding while for a four-wire system the type of grounding must be known, i.e. whether it is effectively (solidly) grounded or non-effeclively (impedance) grounded. 

Thus, an effective solid phase synthesis of aPNA 21-mers was successfully developed. The resulting SPPS protocols can be applied to aU four nucleoamino acids as well as a variety of ancillary amino acids leading to diverse aPNAs structures. 

The experiments are conceptually very straightforward although often more complicated in practice. A chosen target material is irradiated with neutrons (or other projectiles). Following the irradiation the target may, if desired, be thermally or otherwise treated (annealed) to effect solid-state reactions, after which the sample is dissolved and chemically processed in order to separate the various expected products and to measure their yields. 

In conclusion, the following experiments on filtration-washing-deliquoring should be performed to produce data (viscosity of liquids, effective solid concentration, specific cake resistance, cake compressibility, etc.) that are necessary to evaluate times of individual steps of filtration at an industrial scale, i.e. to obtain the proper basis for scale-up of filtration processes measure the filtrate volume versus time make marks on your vacuum flask and take down the time when the filtrate level reaches the mark => no more experiments are needed for preliminary evaluations of filtration properties of slurries initially fines pass the filter medium => recirculate them to the slurry,...

These coatings are also employed as solid lubricants in engine components. Refractory materials such as MoS2 and WSe2 are lamellar compounds and provide very effective solid-state lubrication in spacecraft bearings and components used in radiation environments where conventional organic liquid lubricants are not stable (see Lubrication and lubricants). 

Die next parameter we need is the diffusion coefficient Df of hydrogen peroxide in water. Here, we can assume the approximate value of 10 9 m2/s. However, this coefficient will be needed further in this example for the determination of the effective solid-phase diffusion coefficient, in a calculation that is extremely sensitive to the value of the liquid-phase diffusion coefficient. For this reason, coefficient should be evaluated with as much accuracy as possible. The diffusion coefficient of solutes in dilute aqueous solutions can be evaluated using the Hayduk and Laudie equation (see eq. (1.26) in Appendix I) ... 

Using this expression, the effective solid-phase diffusion coefficient is found to be equal to 3.46 X 10-10 m2/s. This coefficient is related to the liquid-phase coefficient as follows (eq. (3.602)) ... 

Here we report the synthesis and catalytic application of a new porous clay heterostructure material derived from synthetic saponite as the layered host. Saponite is a tetrahedrally charged smectite clay wherein the aluminum substitutes for silicon in the tetrahedral sheet of the 2 1 layer lattice structure. In alumina - pillared form saponite is an effective solid acid catalyst [8-10], but its catalytic utility is limited in part by a pore structure in the micropore domain. The PCH form of saponite should be much more accessible for large molecule catalysis. Accordingly, Friedel-Crafts alkylation of bulky 2, 4-di-tert-butylphenol (DBP) (molecular size (A) 9.5x6.1x4.4) with cinnamyl alcohol to produce 6,8-di-tert-butyl-2, 3-dihydro[4H] benzopyran (molecular size (A) 13.5x7.9x 4.9) was used as a probe reaction for SAP-PCH. This large substrate reaction also was selected in part because only mesoporous molecular sieves are known to provide the accessible acid sites for catalysis [11]. Conventional zeolites and pillared clays are poor catalysts for this reaction because the reagents cannot readily access the small micropores. 

Hafnium is an effective solid solution strengthener at higher temperatures for other alloys such as nickel aluminides (39,40). 

A simple but effective means of preparing supported metal ion catalysts is to employ ion exchange resins. For example, a cobalt-exchanged H-type resin (Dowex 50) was shown43 to be an effective solid catalyst for the autoxidation of acetaldehyde to acetic acid at 20°C. No leaching of cobalt ions from the resin was observed and the catalyst was used repeatedly (5x) without any significant loss of activity. More recently the use of weak acid resins exchanged with cobalt ions as catalysts for the autoxidation of cyclohexane... 

Taddol has been widely used as a chiral auxiliary or chiral ligand in asymmetric catalysis [17], and in 1997 Belokon first showed that it could also function as an effective solid-liquid phase-transfer catalyst [18]. The initial reaction studied by Belokon was the asymmetric Michael addition of nickel complex 11a to methyl methacrylate to give y-methyl glutamate precursors 12 and 13 (Scheme 8.7). It was found that only the disodium salt of Taddol 14 acted as a catalyst, and both the enantio- and diastereos-electivity were modest [20% ee and 65% diastereomeric excess (de) in favor of 12 when 10 mol % of Taddol was used]. The enantioselectivity could be increased (to 28%) by using a stoichiometric amount of Taddol, but the diastereoselectivity decreased (to 40%) under these conditions due to deprotonation of the remaining acidic proton in products 12 and 13. Nevertheless, diastereomers 12 and 13 could be separated and the ee-value of complex 12 increased to >85% by recrystallization, thus providing enantiomerically enriched (2S, 4i )-y-methyl glutamic add 15.
