E-A transitions

From the pseudorotating transition state the inversion process proceeds via an intermediate minimum of D2-symmetry (twist-conformation) and across a symmetry-equivalent second pseudorotational transition state to the inverted chair-conformation. The symmetric boat-form of cyclohexane (symmetry C2v) corresponds to a one dimensional partial maximum, i.e. a transition state (imaginary frequency 101.6 cm-1). It links sym-...

The increase in viscosity at the initial stages of a process is related to formation of a prepolymer, i.e., a transition from a monomer (or a monomer-polymer mixture) with viscosity in the range of 0.01 -1 Pa s to a prepolymer with viscosity 100 -1000 Pa s. The increase in viscosity occurs almost as a jump, i.e., very sharply in a relatively short induction period. A typical example is shown... 

The directions of the transitions between the various phases are indicated by the arrows, i.e., a transition from D to III is possible on application of dry heat. A transition from III to D is impossible unless a strong swelling agent like ammonia is used. A transition from III to I is possible by the application of water and heat or by a prolonged application of water at ambient conditions. The reverse transition is impossible without an intermediate swelling step. The transitions are usually not complete, especially in industries, and a wide range of products can be obtained as indicated by the phase diagram. The ammonia-cellulose complex and cellulose in can also be obtained from cellulose II. There is, however no reversion to cellulose I. 

The expression for ultrasonic attenuation due io E A transition between the vibronic (tunnelling) levels of the (gi e problem for the system with a cubic-type symmetry was obtained in the following form... 

AMS-02 is a magnetic spectrometer which consists of a superconducting magnet and eight planes of Silicon Tracker (STD). It will measure the particle rigidity with 1.5% precision for protons at 10 GV. It is complemented by several subdetectors i.e. a Transition Radiation Detector (TRD), a Time of... 

The density of sea-water is almost independent of depth (1.040-1.045 g cm ) whereas that of liquid carbon dioxide increases with depth see Figure 3.9(b). Down to about 2500 m, liquid carbon dioxide is less dense than sea-water and tends to float upwards. At 2500-3000 m, liquid carbon dioxide is neutrally buoyant i.e., a transition zone in which it neither rises nor sinks), dependent on the sea temperature. Deeper than 3000 m, the liquid is denser than sea-water and sinks downwards to the ocean floor, where it accumulates as a lake, over which a solid layer of crystalline hydrates slowly forms as an ice-like combination of carbon dioxide and water. Within its stability range (low temperature, high pressure), solid C02-hydrate would inspire greater confidence as a permanent store than dissolved or liquid carbon dioxide, although there are few data to say how rapidly carbon dioxide would be leached out by sea-water. 

Within amodule. Boolean conditions, depending on the states of this module and of aU its sub-modules, can be specified. These Boolean conditions, in turn, are used to guard transitions of the behavior descriptions, i.e. a transition may only take place if the corresponding guard condition is satisfied. Furthermore in each module, single instances or containers of instances of the modules types within the scope can be defined to express the internal structure of a module. 

The association of a metallic center (i.e., a transition metal) and TT-heficenic ligands represents a powerful tool to elaborate multifunctional systems and... 

In the transition region for a between 2100 and 6000, the empirical equations are not well defined just as in the case of fluid friction factors. No simple equation exists for accomplishing a smooth transition from heat transfer in laminar flow to turbulent flow, i.e., a transition from Eq. (4.5-4) at a = 2100 to Eq. (4.5-8) at a T/r = 6000. 

Proteins are known to undergo a process of denaturation upon heating or changing the solvent condition. By denaturation we refer to the loss of the specific function—say, enzymatic activity—of the protein. It is also known that this process involves the breakdown of the specific three-dimensional structure of the protein, which is essential for its function, i.e., a transition from a well-defined folded form (F) into a random or partially random unfolded form (U). We denote this process schematically as...
