[1] The Apollo lunar heat flow measurements gave values of 21 and 16 mW m 2 which, after extrapolation based on thorium abundances, yields a global estimate of 18 mWm . A refinement of the assumptions of the subsurface structure and the resulting focusing of heat flux later led to a revision of the global value to 12 mWm . We think that to date none of the models linking the Apollo heat flow me...

The Apache Point Observatory Lunar Laser-ranging Operation (APOLLO) is a nextgeneration lunar laser ranging (LLR) campaign aimed at order-of-magnitude improvements in tests of gravitational physics via millimeter range precision. We will employ the 3.5 m telescope at the Apache Point Observatory (APO), located in southern New Mexico at an altitude of 2800 m. As a result of the large aperture si...

This paper deals with a study of geologic structures using 8 X enlargements of Apollo-Soyuz Test Project color photographs. The two study areas are Abu Rawdsh and Whdi el NatrQn; both are in the northern part of the Western Desert of Egypt. Because the structures are small, aerial photographs were studied and field checks were made to verify the findings from Apollo-Soyuz photographs. The Apoll...

Introduction: Lunar impact-melt breccias contain metal grains from the meteorites that formed the breccias. Because the breccias contain clastic material that may derive from older breccias, metal grains from earlier impacts may be present, too. The large subset of moderately mafic (8– 12% FeO), KREEP-rich (“LKFM”) melt breccias is particularly important because (1) these are the melt breccias ...

INTRODUCTION The Apollo system (Penumbra Inc, Alameda, California, USA) is a low profile irrigation-aspiration system designed for the evacuation of intracranial hemorrhage. OBJECTIVE To demonstrate the feasibility of using Apollo in combination with cone beam CT guidance. METHODS Parenchymal (n=1) and mixed parenchymal-intraventricular hematomas (n=1) were created in cadaver heads using a ...

This paper reviews the early years of remote sensing of the earth’s surface, as distinguished from its atmosphere, and shows the influence of manned space flight, in particular the Apollo Program. The first orbital-altitude pictures of the earth were taken from sounding rockets in the 1950s, and eventually led to terrain photography by astronauts of the Mercury, Gemini, and Apollo Programs usin...

Yersinia pseudotuberculosis is a bacterium pathogenic to humans and other mammals; however, its insecticidal activity has also been documented in laboratory studies. A small population of Apollo butterfly (Parnassius apollo), reconstituted from less than 30 individuals in 1990s, occurs in Pieniny National Park (Poland). In this report, we demonstrate that a DNA fragment specific to Y. pseudotub...

We investigate the dependence of hadronic ratios on the number of projectile participants using a thermal model incorporating exact baryon number and strangeness conservation. A comparison is made with results from Au − Au collisions obtained at the BNL-AGS. Preliminary results on the dependence of hadronic ratios on the number of projectile participants have recently been presented by the E866...

Recent experiments on rare kaon decays are described, with emphasis on the program at the Brookhaven National Laboratory Alternating Gradient Synchrotron. New limits on the modes KL + pe and Kr, -v ee and a preliminary new measurement of the Kr. + pp branching ratio are presented from AGS Experiment 791. Other modes, including K+ + x+p’+e-, K+ + r+ + nothing, and KL -+ r’e+e-, which have been t...
