Ultra - violet absorption cross sections of isotopically substituted nitrous oxide species : 14 N 14 NO , 15 N 14 NO , 14 N 15 NO and 15 N 15 NO

The isotopically substituted nitrous oxide species 14N14NO, 15N14NO, 14N15NO and 15N15NO were investigated by ultra-violet (UV) absorption spectroscopy. High precision cross sections were obtained for the wavelength range 181 to 218 nm at temperatures of 233 and 283 K. These data are used to calculate photolytic isotopic fractionation constants as a function of wavelength. The fractionation con...

DEV 14 and HotMobile 15

T Fifth ACM Symposium on Computing for Development (DEV-5) was held on 5–6 December 2014 in San Jose, California. In its fifth edition, DEV continued its progress to becoming the premier venue to present original and innovative work on the applications, technologies, architectures, and protocols for computing in developing regions. In particular, the conference highlighted research results from...

15 Years of Exerience with 100% Generator

This paper discusses the application of three different 100% stator ground fault protection schemes. Two third-harmonic methods and a low frequency-injection method are discussed. Third-harmonic schemes have been widely applied on generators within the U.S. to provide stator ground fault protection over the entire stator winding. In many cases, however, these schemes have been found not to be a...

15/14+o(1))] modulo primes

Let λ be a fixed integer, λ ≥ 2. Let s n be any strictly increasing sequence of positive integers satisfying s n ≤ n 15/14+o(1). In this paper we give a version of the large sieve inequality for the sequence λ sn. In particular, we prove that for π(X)(1 + o(1)) primes p, p ≤ X, the numbers λ sn , n ≤ X(log X) 2+ε are uniformly distributed modulo p.
