Gas chromatographic mass spectrometric analysis using head space was carried out on the roots, stems and leaves of three different species of Mint grown in Egypt.This study was carried out aiming to investigate the chemical composition of the essential oils obtained from roots, stem and leaves of Mentha piperita L, Mentha spicata Var.crispa L.and D
Basic Human Values of the Russian and European teachers
Basic Human Values of the Russian teachers are compared with those of their colleagues from the 27 European countries, using the Schwartz Value Survey data collected in the 1990s.It was found that the average Russian teacher is extremely high in Security and extremely low in Hedonism.In addition the Russian teachers often leave their colleagues beh
The claudin-like apicomplexan microneme protein is required for gliding motility and infectivity of Plasmodium sporozoites.
Invasion of host cells by apicomplexan parasites such as Toxoplasma and Plasmodium spp requires the sequential secretion of the parasite apical organelles, Ointment the micronemes and the rhoptries.The claudin-like apicomplexan microneme protein (CLAMP) is a conserved protein that plays an essential role during invasion by Toxoplasma gondii tachyzo
Intra-pulse modulation recognition using short-time ramanujan Fourier transform spectrogram
Abstract Intra-pulse modulation recognition under negative signal-to-noise ratio (SNR) environment is a research challenge.This article presents a robust algorithm for the recognition of 5 types of radar signals with large variation range in the signal parameters in low SNR using the combination of the Short-time Ramanujan Fourier transform Drop-In
