Abstract This paper discusses the use of nanomaterials for the improved performance of time-of-flight particle Countertop Microwave detectors based on secondary electron emission (SEE).The purpose of the research presented in this paper is to find a nanomaterial that has a higher SEE than gold.In this article, we present a measurement of the SEE pr
Factors were examined that could be responsible for the predominance of Coccinella septempunctata (C7) in most habitats of the Palaearctic and for its successful invasion of the Nearctic Region.C7 is euryphagous, but less polyphagous than Harmonia axyridis or Coleomegilla maculata in that it cannot develop or reproduce on non-aphid food.The intragu
Birds constitute a zoological group which is considered to be a good indicator of balance and biological diversity.The aim of Flywheel this study was to investigate the birds of the region on Tamanresset which is situated in the south of Algeria and has an area of 554.000 km2.Direct observations with camera and a pair of binoculars, supported by or
The understanding of the nature and behavior of ice sheets in past warm periods is important for constraining the potential impacts of future climate change.The Pliocene warm period (between 3.264 and 3.025 Ma) saw global temperatures similar to those projected for future climates; nevertheless, Pliocene ice locations and extents are still poorly c
