Forward Edge

This article traces the evolution of the concept of the leading edge in Kohut's work. The leading edge is defined as the growth-promoting dimension of the transference. The authors argue that although Kohut did not ever use the term explicitly in his writings—Marian Tolpin (2002), one of Kohut's gifted pupils, introduced the concept into the psychoanalytic literature in the form of the forward edge—the idea of the leading edge was already present in nascent form in Kohut's earliest papers and became ever more central as his psychology of the self evolved and the concept of the selfobject transference took center stage. Kohut, it is argued, could not fully develop the idea of working with the leading edge for fear of being accused of advocating for a corrective emotional experience in psychoanalytic treatment. However, in his posthumous empathy paper (1982) Kohut came as close as he could to endorsing the leading edge as pivotal in all psychoanalytic work.

Forward Edge

After optimizing the conditions, including nutrients and temperature, swarming of Bacillus subtilis 3610 was obtained on a synthetic, fully defined medium. The swarms formed highly branched (dendritic) patterns, generated by successive waves of moving cells. A detailed microscopic in situ analysis of swarms 1 and 2 revealed varied cell morphologies and a remarkable series of events, with cells assembling into different ‘structures’, as the architecture of the swarm developed. Long filamentous cells begin to form before the onset of the first swarming (11 h) and are again observed at later stages in the interior of individual mature dendrites. Swarm 2, detected at 18–22 h, is accompanied by the rapid movement of a wave of dispersed (non-filamentous) cells. Subsequently at the forward edge of this swarm, individual cells begin to cluster together, gradually forming de novo the shape of a dendrite tip with progressive lengthening of this new structure ‘backwards' towards the swarm centre. In both swarms 1 and 2, after the initial clustering of cells, there is the progressive appearance of a spreading monolayer of rafts (4–5 non-filamented cells, neatly aligned). The alternative possible roles of the rafts in the development of the swarm are discussed.

The Given

In the given review the problem of improvement of aerodynamic characteristics of the low-sized aircraft is considered with point of view of the fundamental phenomena of the mechanics of liquid, gas and plasma. It is a problem of the local boundary layer separation (separated bubbles) and flow separation from a wing forward edge at which all global structure of a flow varies. The review of the works establishing this interrelation and methods of the influence, eliminating harmful consequences of the separations is submitted. The method of separation elimination with help of a wavy surface, as the most perspective and easily sold on practice is in more details allocated in this review. The second part of the review is devoted to the analysis of a flow of elements of designs of various low-sized aircraft with indication of probably problem places where the flow is realized at Reynolds number less than 106 and where can arise the local separations. Application of a wavy surface in such places can improve aerodynamic characteristics of the flying device promoting its more effective operation

AbstractIn this article we show why flying and rotating beer mats, CDs, or other flat disks will eventually flip in the air and end up flying with backspin, thus, making them unusable as frisbees. The crucial effect responsible for the flipping is found to be the lift attacking not in the center of mass but slightly offset to the forward edge. This induces a torque leading to a precession towards backspin orientation. An effective theory is developed providing an approximate solution for the disk’s trajectory with a minimal set of parameters. Our theoretical results are confronted with experimental results obtained using a beer mat shooting apparatus and a high speed camera. Very good agreement is found.
