The EAS-TOP and MACRO Collaboration * We report the analysis of the N e-N µ coincident events collected by the MACRO/EAS-TOP collaboration at the Gran Sasso Laboratories. The result points to a primary composition becoming heavier around the knee of the primary spectrum (in the energy region 10 15 − 10 16 eV). The result is in very good agreement with the measurements of EAS-TOP alone at the su...

The biopsy may very well be the most paramount procedure confronting the dentist and successful tissue diagnosis depends on proper surgical biopsy technique. Yet, how many who are faced with this procedure really know the principles involved and can carry them, out flawlessly as they must be? The practitioner who attempts this procedure without being aware of principles involved may prevent mor...

An analysis of attenuation and absorption lengths of the electron number using data of the KASCADE air shower experiment is presented. The following methods are used to determine these quantities: The method of constant intensity, the attenuation of the electron number at the knee with increasing atmospheric depth, the decrease of the flux at a constant electron number with increasing zenith an...

A growing number of social scientists fear that marriage may be on the rocks and few doubt that matrimony, as we have known it, has undergone a wrenching period of change in the past several decades. Andrew Cherlin, a leading sociologist of the family, speaks of "the de-institutionalization of marriage," conceding a point to conservative commentators who have argued that marriage and the family...

BACKGROUND Biomedical scientists need to access figures to validate research facts and to formulate or to test novel research hypotheses. However, figures are difficult to comprehend without associated text (e.g., figure legend and other reference text). We are developing automated systems to extract the relevant explanatory information along with figures extracted from full text articles. Such...

Although most philosophical accounts about model/world relations focus on structural mappings such as isomorphism, similarity has long been discussed as an alternative account. Despite its attractions, proponents of the similarity view have not provided detailed accounts of what it means that a model is similar to a realworld target system. This article gives the outlines of such an account, dr...

The light signal measured by fluorescence telescopes receives strongly depending on the shower geometry with respect to the detector a non-negligible contribution from additionally produced Cherenkov light. This Cherenkov contribution has to be accounted for to determine primary parameters properly. In comparison to the previous ansatz used by other experiments, the impact of a new analytical d...

Data taken during half a year of operation of 10 LOPES antennas (LOPES-10), triggered by EAS observed with KASCADE-Grande have been analysed. We report about the analysis of correlations of radio signals measured by LOPES-10 with extensive air shower events reconstructed by KASCADE-Grande, including shower cores at large distances. The efficiency of detecting radio signals induced by air shower...

Tourism specialization on the one hand may be a successful tool to achieve fast economic growth, and, on the other hand, may be detrimental for natural resources. Finding the right balance between economic benefits and environmental costs is essential to reach sustainable development, ensuring that tourist numbers do not exceed the carrying capacity of the tourism destination. In this context, ...
