Laser pulses fired at retroreflectors on the Moon provide very accurate ranges. Analysis yields information on Earth, Moon, and orbit. The highly accurate retroreflector positions have uncertainties less than a meter. Tides on the Moon show strong dissipation, with Q = 33 ± 4 at a month and a weak dependence on period. Lunar rotation depends on interior properties; a fluid core is indicated wit...

There has been a renewed interest in exploration of the moon in the past few years and a number of space missions are planned by various countries during this decade. The Indian Space Research Organization has also been discussing the possibility of an orbiter mission to the moon for remote sensing and has debated the scientific goals for such a mission in various fora such as the annual meetin...

This paper reports on a study of practitioners in engineering design striving to transform their work practices so as to be able to cope with complex interdependencies across global production networks. As a key feature of these budding coordinative practices, practitioners are trying to build computational ʻmodelsʼ of the ʻdesign spaceʼ of their enterprise. The paper examines the difficulties ...

BACKGROUND Man, since ancient times, has been convinced of, and has researched scientific evidence that the barometric and gravitational forces play an important role in structural and biological variation of the planets, influencing the various forms of life. In particular, the synergistic relationships between variations in atmospheric pressure and gravitational forces on human gestation peri...

In the experiment reported here, 30 participants made a lexical decision on 120 spoken words and 120 spoken nonwords. The words had either an upward (e.g. ‘moon’) or downward (e.g. ‘sewer’) spatial association, or they were neutral in this respect (e.g. ‘letter’). Participants made their lexical decisions by fixating a target located either above or below the centre of the screen, counterbalanc...
