Effects of an Acoustic Stimulus upon Growth, Antibody Synthesis and Leukocyte Values

Physiologic effects of an acoustic stimulus of 1.0 Khz at 96 db(A) upon female hooded rats are discussed. Six possible reasons are offered for failure to attain statistical significance, except in intermediate aspects, between control and experimental animals

The James Webb Space Telescope Mission

Twenty-six years ago a small committee report, building on earlier studies, expounded a compelling and poetic vision for the future of astronomy, calling for an infrared-optimized space telescope with an aperture of at least $4m$. With the support of their governments in the US, Europe, and Canada, 20,000 people realized that vision as the $6.5m$ James Webb Space Telescope. A generation of astronomers will celebrate their accomplishments for the life of the mission, potentially as long as 20 years, and beyond. This report and the scientific discoveries that follow are extended thank-you notes to the 20,000 team members. The telescope is working perfectly, with much better image quality than expected. In this and accompanying papers, we give a brief history, describe the observatory, outline its objectives and current observing program, and discuss the inventions and people who made it possible. We cite detailed reports on the design and the measured performance on orbit.Comment: Accepted by PASP for the special issue on The James Webb Space Telescope Overview, 29 pages, 4 figure

n_TOF experiment : past, present and future

The neutron Time-of-Flight facility at CERN was built to measure the neutron capture and fission cross sections. A short description of the facility, the detectors and the data analysis techniques will be illustrated. A short review of the preliminary results on the fission cross sections is presented together with the implications in fundamental nuclear physics and in nuclear technologies. Future perspectives both for the experimental campaign and for the upgrade of the facility are discussed

Study of Neutron-Induced Fission Cross Sections of U, Am, and Cm at n_TOF

Neutron induced fission cross sections of several isotopes have been measured at the CERN \u1e49TOF spallation neutron facility. Between them some measurements involve isotopes (233U, 241Am, 243Am, 245Cm) relevant for applications to nuclear technologies. The \u1e49TOF facility delivers neutrons with high instantaneous flux and in a wide energy range, from thermal up to 250 MeV. The experimental apparatus consists of an ionization chamber that discriminates fission fragments and \u3b1 particles coming from natural radioactivity of the samples. All the measurements were performed referring to the standard cross section of 235U
