In 1922 Alexander Fleming described the remarkable bacteriolytic activity of an enzyme, lysozyme, which was widely distributed in tissues and secretions (1). Lysozyme (muramidase) is a cationic enzyme, tool wt 14,307, which hydrolyses N-acetyl muramic /3-1, 4 N-acetyl glucosamine linkages in the bacterial cell wall (2). Although a great deal is known about its structure and enzymology its funct...

Meteor radars have been used to measure the horizontal winds in the mesosphere and lower thermosphere over Castle Eaton (52 N) in the UK and over Esrange (68 N) in Arctic Sweden. We consider a 16-year data set covering the interval 1988–2004 for the UK and a 6-year data set covering the interval 1999–2005 for the Arctic. The signature of the 12.42-h (M2) lunar tide has been identified at both l...

In this note we explore the possibility of measuring the action of the intrinsic gravitomagnetic field of the rotating Earth on the orbital motion of the Moon with the Lunar Laser Ranging (LLR) technique. Indeed, expected improvements in it should push the precision in measuring the Earth-Moon range to the mm level; the present-day Root-Mean-Square (RMS) accuracy in reconstructing the radial co...

The "Kitab al-abniya an haqa iq al-adwiya" (Book of the Foundations of Pharmacognosy) also Known as "Rozat ol-ons wa manfa 'ar on-nafs" is the most ancient medical book in Persian (Farsi), which was written by Abu Mansur Movaffaq ibn Ali Heravi during the period of Mansur ibn Noh Samani between the years 350 to 366 lunar hegira. The book deals with 584 mineral, herbal and animal-based drugs. Th...

One of the oqtical datasets for optimal selection of future lunar lana_ng sites is local, to regional-scale topography. Lunar base site selection will require such data for hoth engineering and scientific olX,rations purposes. The Lunar Geosctence Orbiter or Lunar Obsert_or is the ideal precursory science mission from which to obtain this required information. We suggest that a simple laser alt...

A global scheme of Lunar-Earth Information Network is proposed in this paper. It is composed of a lunar-earth Messenger, a lunar Orbiter and a Lunar Probe net, through which an information collection and communication network is formed. Moreover, the triune exploration and project features are described in detail. Keyword: LunarNet, Messenger, Orbiter, Lunar Probes

Introduction: Since the discovery of ice in cold, permanently shadowed polar craters on Mercury[1], debate has reopened over the presence of ice in similar environments on the Moon. Though the Moon has similar shadowed craters currently, this has not always been the case. Here we examine a 4.5 billion year history of insolation in the lunar polar environment and the resulting surface and subsur...

Juvenile noble crayfish, Astacusastacus (Crustacea, Astacidea) in the second year of age were kept in the laboratory for a twelve-month period under continuing "summer conditions" (LD 16:8, 19°C). Molting processes in this population could be synchronized by artificial moonlight cycles. Peaks of exuviations occurred at "new moons". Males showed a slightly higher degree of synchronization than f...
