We have examined the variability and potential adaptive signi®cance of the wavelengths of light produced by gelatinous zooplankton. Bioluminescence spectra were measured from 100 species of planktonic cnidarians and ctenophores collected between 1 and 3500 m depth. Species averages of maximal wavelengths for all groups ranged from 440 to 506 nm. Ctenophores (41 species) had characteristically l...

A one-dimensional, physically based numerical model was constructed to describe the isotopic enrichment observed in throughfall of snow intercepted on evergreens. The process of enrichment is similar to that which results in formation of depth hoar in snowpack. On-site data were obtained at a high-altitude (3500 m) watershed in the Colorado Rocky Mountains. The model includes the ambient atmosp...

Borexino is a large unsegmented calorimeter featuring 300 tons of liquid scintillator, contained in a 8.5 meter nylon vessel, viewed by 2200 PMTs. The main goal of Borexino is the study, in real time, of low energy solar neutrinos, and in particular, the monoenergetic neutrinos coming from Be, which is one of the missing links on the solar neutrino problem. The achievement of high radiopurity l...

This paper presents results of an empirical research study of the Unified Modeling Language (UML) use in practice. We employed a selective range of research methodologies including in-depth semi structured interviews and quantitative analysis of > 3500 UML diagrams related to open source projects in GitHub. The aim of the study is to provide greater understanding about the use of UML and to par...

An experimental investigation was conducted to explore the validity of classical correlations based on conventionalsized channels for predicting the thermal behavior in single-phase flow through rectangular microchannels. The microchannels considered ranged in width from 194 lm to 534 lm, with the channel depth being nominally five times the width in each case. Each test piece was made of coppe...

[1] A solution of the lidar equation is discussed, that permits combining backscatter and depolarization measurements to quantitatively distinguish two different aerosol types with different depolarization properties. The method has been successfully applied to simultaneous observations of volcanic ash and boundary layer aerosol obtained in Exeter, United Kingdom, on 16 and 18 April 2010, permi...

The previous article about material screening for Gerda points out the importance of strict material screening and selection for radioimpurities as a key to meet the aspired background levels of the Gerda experiment. This is directly done using low-level gamma-spectroscopy. In order to provide sufficient selective power in the mBq/kg range and below, the employed gamma-spectrometers themselves ...
