DETERMINATION OF OZONE CONCENTRATION AND ITS EFFECT ON DEGRADATION OF MATERIALS
The ongoing Covid-19 pandemics showed the need for the effective decontamination of environment and surfaces. One of the options could be the use of gas ozone.

The PADME experiment, by using the positron beam of the Frascati laboratory, aims at searching for signals of a dark photon, A′ . It will evaluate the final state missing mass of the process e+ e- → A′ γ by knowing the beam energy and measuring the four-momentum of the ordinary recoil photon.

Accelerators and detectors [PDF]
The developing understanding of particle physics, especially in the past 60 or so years, has been largely paced by the evolution of high-energy accelerators and detectors. We restrict ourselves here to describing crucial developments in accelerators related to high-energy particle collisions.

The latest synchrotron radiation sources have the capability to produce X-ray beams with a photon flux that can be up to three orders of magnitude higher than previous-generation facilities, and that are not manageable by the currently available 2D ...

Night-Time Detection of Subpixel Emitters with VIIRS Mid-Wave Infrared Bands M12–M13
In this paper, we present a new approach to subpixel infrared (IR) emitter detection in VIIRS mid-wave (MWIR) infrared bands M12–M13 at night, based on the presence of a tightly clustered background diagonal present in full granule scattergrams of M12 ...

The unpredictably eruptive dynamics of spruce budworm populations in eastern Canada
We examine historical population data for spruce budworm from several locations through the period 1930–1997, and use density‐dependent recruitment curves to test whether the pattern of population growth over time is more consistent with Royama's (1984; Ecological Monographs 54:429–462) linear R(t) model of harmonic oscillation at Green River New ...

Small spacecraft for the registration of micrometeorites and space debris
Small spacecraft (SSC) is exposed to fluxes of micrometeoroids and space debris during its flight in space environment. These effects may result in the destruction of the SSC.
