The nature .and variety of displays on the convention on: "Bee items: Prop­ erties, functions and Apitherapy" held at Tel-Aviv on may perhaps 26--30, 1996, emphasize the expanding curiosity of physicians, practitioners, scientists, herbalists, dieticians, cosmeti­ cians, microbiologists, and beekeepers in several aspects of bee items. This quantity involves a range of 31 contributions offered on the convention and which supply details at the current prestige of our wisdom during this quarter. despite their range, they replicate the mainstream of the convention, particularly: "Imported" Prod­ ucts (honey, pollen and propolis), Exocrine Secretions of employees (venom, royal jelly). Toxicity and Contaminants, qc, advertising, Apitherapy, Cosmetics, and so forth. considering antiquity, honey in addition to different bee items have been used as nutrients, as a treatment for diseases of people and animals, and as cosmetics. we are hoping that this quantity will give a contribution to interdisciplinary reports on chemical composition, pharmacological results, nutrients, and different features of bee items. serious and independent experimental learn could get to the bottom of the but unknown composition and mode of motion of bee items and elucidate many unanswered questions. The noteworthy positive aspects of this convention have been the members from all elements of the area and of other cultural backgrounds, who shared their willing curiosity and curios­ ity concerning honey bees and their items. We thank them all for his or her own con­ tribution to the luck of this conference.

Pixelization Paradigm: First Visual Information Expert Workshop, VIEW 2006, Paris, France, April 24-25, 2006, Revised Selected Papers

The pixelization paradigm states as a postulate that pixelization tools are wealthy and are worthy exploring so far as attainable. actually, we expect that the energy of those equipment lies of their simplicity, of their high-density approach of knowledge illustration estate and of their compatibility with neurocognitive procedures.

Progress in Lasers and Laser Fusion

This quantity incorporates a element of the shows given on the consultation on Laser-Fusion and Laser enhance­ ment of Orbis Scientiae II, held on the heart for Theoretical reports, college of Miami, from January 20 via January 24, 1975. This moment within the new sequence of conferences held on the CTS strove to enforce the objectives professed within the association of Orbis Scientiae in 1974, particularly to motivate scientists in numerous disci­ plines to interchange perspectives, not just with colleagues who proportion comparable learn pursuits, but in addition to acquaint scientists in different fields with the major principles and present leads to every one zone represented.

Complete Atlas of Polarization Observables in Deuteron Photodisintegration Below Pion-Threshold

For the 1st time, a whole calculation of all 288 polarization observables of deuteron photodisintegration for polarized photons and an orientated deuteron goal is gifted for energies under +-production threshold. The observables are calculated inside of a nonrelativistic framework yet with inclusion of lowest-order relativistic results.

Cohomology Theories for Compact Abelian Groups

Of all topological algebraic buildings compact topological teams have might be the richest idea in view that eighty many alternative fields give a contribution to their learn: research enters throughout the illustration concept and harmonic research; differential geo­ metry, the idea of actual analytic services and the speculation of differential equations come into the play through Lie team idea; element set topology is utilized in describing the neighborhood geometric constitution of compact teams through restrict areas; worldwide topology and the speculation of manifolds back playa position via Lie team concept; and, in fact, algebra enters throughout the cohomology and homology thought.

The major variations seen in overall antibacterial activity are due to variation in the level of hydrogen peroxide that arises in honey, and in some cases to the level of non-peroxide factors. Hydrogen peroxide can be destroyed by components of honey: it can be degraded by reaction with ascorbic acid and metal ions, and by the action of the enzyme catalase which comes from the pollen and nectar of certain plants, more from the nectar. Also, very large differences have been found between honeys from different floral sources in the thermal stability of their glucose oxidase content, and in the sensitivity of this hydrogen peroxide-producing enzyme to denaturation by light because of a photosensitizing component that comes from some floral sources.
