Natural attractive boundary

Exercise. The boundaries + oo of the ordinary diffusion equation dPjdt = d2P/dy2 are natural attractive, type (ii), but L3 and L4 diverge, so that no stationary distribution exists. 

Further examples of the utility of the allylic sulfoxide-sulfenate interconversion in the construction of various biologically active natural products include intermediates such as the /Miydroxy-a-methylene-y-butyrolactones (e.g. 63)128 and tetrahydrochromanone derivative 64129. Interestingly, the facility and efficiency of this rearrangement has also attracted attention beyond the conventional boundaries of organic chemistry. Thus, a study on mechanism-based enzyme inactivation using an allyl sulfoxide-sulfenate rearrangement has also been published130 131. 

In contrast, stabilization of boundary layer by contouring the airfoil surface to achieve favourable pressure gradient as a passive way is found to be practical and attractive. The resultant section is known as the Natural Laminar Flow (NLF) airfoil and this is an area which has been under renewed investigation over the last three decades. Early efforts of designing... 

A quantity which has also attracted a good deal of attention in connection with dipolar and associating fluids is the dielectric constant. In finite samples of volume V (used in computer simulations) the natural quantity to measure is the fluctuation of the total dipole moment of the system, (M2), M = YliLi Mi> where /a., are the dipole moments of the individual molecules. For nonpolarizable molecules in the periodic boundary conditions and with the long-range forces treated by the Ewald summation the dielectric constant, e, is... 

The concrete biochemistry of cortical enhancer regulation, the puzzle of the amalgamation of order and chaos in the human brain is still unsolved. As usual, attractive descriptions remedy such deficiencies. Freud s work was the hitherto most influential description of the coexistence of rational and irrational, conscious and unconscious, in the human brain. It is no accident that his fascinating writings, enjoyable readings closer to fiction than science, have always deeply influenced many artists. Freud also provided a delightful interpretation of dreams at the boundary between art and science. It was probably the pseudo-scientific nature of his brilliant books that precluded him from receiving the well-deserved Nobel Prize for literature. 

A recent SECM study of electrochemical catalysis at the ITIES was based on a similar concept (23). The ITIES was used as a model system to study catalytic electrochemical reactions in microemulsions. Microemulsions, i.e., microheterogeneous mixtures of oil, water, and surfactant, appear attractive for electrochemical synthesis and other applications (63). The ITIES with a monolayer of adsorbed surfactant is of the same nature as the boundary between microphases in a microemulsion. The latter interface is not, however, directly accessible to electrochemical measurements. While interfacial area in a microemulsion can be uncertain, the ITIES is well defined. A better control of the ITIES was achieved by using the SECM to study kinetics of electrochemical catalytic reduction of //zms-l, 2-dibromo-cyclohexane (DBCH) by Co(I)L (the Co(I) form of vitamin B12) ...
