Creation of the precision magnetic spectrometer SCAN-3

The new JINR project [1] is aimed at studies of highly excited nuclear matter created in nuclei by a high-energy deuteron beam. The matter is studied through observation of its particular decay products - pairs of energetic particles with a wide opening angle, close to 180°. The new precision hybrid magnetic spectrometer SCAN-3 is to be built for detecting charged (π±, K±, p) and neutral (n) particles produced at the JINR Nuclotron internal target in dA collisions. One of the main and complex tasks is a study of low-energy ηA interaction and a search for η-bound states (η-mesic nuclei). Basic elements of the spectrometer and its characteristics are discussed in the article

Рослинні рештки Syringa vulgaris L. як фактор алелопатичної ґрунтовтоми

Allelopathic properties of vegetating organs and plant remains of Syringa vulgaris L. were studied. The allelopathic activity of plant remains was 1.5–6 times higher and depended on cultivars. The high positive correlation between allelopathic activity of plant remains and content of phenolics was established. The effect of plant remains on biochemical characteristics and phytotoxicity of soil rhizosphere was investigated.Вивчали алелопатичні властивості вегетуючих органів та рослинного опаду Syringa vulgaris L. Алелопатична активність рослинного опаду була вищою в 1,5–6,0 разів та залежала від сорту. Встановлено тісний позитивний взаємозв’язок між активністю рослинних решток та вмістом фенольних речовин. Досліджено вплив рослинних решток на біохімічний стан та фітотоксичність прикореневого середовища
