International Journal of Modern Physics A, 1998 In this article old and new relations between gauge fields and strings are discussed. We add new arguments that the Yang–Mills theories must be described by the noncritical strings in the five-dimensional curved space. The physical meaning of the fifth dimension is that of the renormalization scale represented by the Liouville field.

Proceedings of the Royal Society B: Biological Sciences, 2017 World experts of different disciplines, from molecular biology to macro-ecology, recognize the value of cave ecosystems as ideal ecological and evolutionary laboratories. Among other subterranean taxa, spiders stand out as intriguing model organisms for their ecological role of top predators, their unique adaptations to the hypogean medium

New Trends and Issues Proceedings on Humanities and Social Sciences, 2019 This paper aims to discuss the impact and importance of the karstic caves, which are effective on the emergence and development of cave art and the rocks that generate them. The origin of cave traces to 40 thousand years and the creation of many more works of art and the importance of the rocks to the present day is very important.

International Journal of Speleology, 2005 The physical characteristics of radon are reported as well as its sources,the transport in rock and its behaviour in caves. Then,the instruments,both active and passive, used for the measurement of radon concentration are discussed by taking into accounttheir respective advantages and disadvantages for the use in the cave environment.

Journal of Orthopaedic & Sports Physical Therapy, 2016 In this month's Viewpoint editorial, Drs Reiman, Thorborg, and Hölmich provide a timely critique of the escalating diagnosis and surgical management of femoroacetabular impingement. They deconstruct an enthusiasm fueled by the imperfect evidence of passive observation. While almost always well meaning and not invaluable, it is too often enchanted with

Antiquity, 1995 It is over a decade since Palaeolithic parietal art was first spotted in Europe on exposed open-air surfaces—cave art without the caves. Now the major site in Portugal is threatened by the lake behind a river-dam under construction. Here is a report on what cave art outside the caves amounts to, and of the confrontations over the Côa site that were in ...
