Mechanical function

Some of these software packages also have semiempirical or molecular mechanics functionality. However, the primary strength of each is ah initio calculation. There are also ah initio programs bundled with the Unichem, Spartan, and Hyperchem products discussed previously in this appendix. 

Mechanically Functional. Refractory coatings are used in engine parts, landing gears, soft-film lubricants, and cutting and forming tools (see... 

The high cost for machinery replacements and downtime makes machinery operational reliability very important however, with the current and projected increases in fuel costs, aerothermal monitoring has become very important. Aerothermal monitoring can provide not merely increased operational efficiency for turbomachinery but, when combined with mechanical monitoring, it provides an overall, more effective system than one that monitors only the mechanical functions or aerothermal functions. 

Electric control An electrical device that controls some mechanical function, such as a damper control. 

The enantioselectivity of the macrocyclic CSPs are different in each of the operating modes, probably because of different separation mechanisms functioning in the different solvent modes. The possible chiral recognition mechanisms for three mobile phase compositions on glycopeptide phases are listed in Table 2-3 in descending order of strength.

Filter pack. Filter pack is the term used to describe the materials placed in the annular space between the screen and the formation (Figure 1). Aller et al. and Driscoll provide a discussion of the purpose and selection of filter pack materials. The filter pack serves a number of important mechanical functions. During well construction, it helps to keep the well screen centered in the borehole and acts to block the sealant from entering the well screen. The filter pack also improves hydraulic conductivity between the well screen and the formation, prevents formation materials from migrating to the well screen by acting as a filter, and helps support the screen and borehole. ...

The horizontal exposure method is not very adequate for the OSU RHR calorimeter, because the heat reflected from the aluminum foil onto the sample is much lower than the heat generated by the glow bars. Since the OSU calorimeter is based on the adiabaticity of the measurements, any heat losses will represent inaccurate results. The reflection on the aluminum foil is also uneven. Moreover, the use of higher radiant energy causes problems with the mechanical functioning of the instrument (bending and buckling of the back plate). 

Mechanical functions of cells require interactions between integral membrane proteins and the cytoskeleton 29 The spectrin-ankyrin network comprises a general form of membrane-organizing cytoskeleton within which a variety of membrane-cytoskeletal specializations are interspersed 29 Interaction of rafts with cytoskeleton is suggested by the results of video microscopy 29... 

Mechanical functions of cells require interactions between integral membrane proteins and the cyto-skeleton. These functions include organization of signaling cascades, formation of cell junctions and regulation of cell shape, motility, endo- and exocytosis. Several different families of membrane-associated proteins mediate specific interactions among integral membrane proteins, cytoskeletal proteins and contractile proteins. Many of these linker proteins consist largely of various combinations of conserved protein-association domains, which often occur in multiple variant copies. 

Nearly all domestic appliances are using more and more electronics. Mechanical functions are replaced by electronic devices, mainly sensors and electromechanical actuators (such as pumps or electromotors) and microelectronic control systems. 

Diphenyl ditelluride adds to alkynes upon irradiation with a tungsten lamp in the absence of solvent to give 1,2-bis(phenyltelluro)alkenes (Equation (67)).191 The ( )-isomers are obtained as the major product through a radical chain mechanism. Functionalized internal alkynes such as dimethyl acetylenedicarboxylate and dihaloalkynes XCCX (X = C1 or Br) are able to participate in the reaction.192...
