У праці досліджено просторову стохастичну логістичну модель динаміки популяції певного виду. Досліджено критичні значення параметру смертності індивідуумів і знайдено поріг вимирання популяції за допомогою аналітичних методів і проведення симуляцій динаміки популяції. Порівняно аналітичні апроксимації порогу вимирання популяції з результатами симуляцій, на базі отриманих даних знайдені критичні...

Melioidosis is an infectious disease caused by Burkholderia pseudomallei and endemic in Southeast Asia. One hundred and forty six clinical isolates of B. pseudomallei from different states in Malaysia were obtained and molecular typing was carried out using pulsed-field gel electrophoresis (PFGE). Overall, nine clusters were successfully identified. Burkholderia pseudomallei isolates used in th...

متن کامل9-Ethyl-3,6-diformyl-9H-carbazole
The structure of the title compound, C(16)H(13)NO(2), was determined as a part of a project on the synthesis of new compounds which can make two-photon absorptions. In the crystal structure, both aldehyde groups are located within the carbazole plane. One of these groups is disordered and was refined using a split model with site-occupation factors for each position of 0.5.

The title compound, C42H48O6, was obtained via formyl-ation of 25,26,27,28-tetra-propoxycalix[4]arene with dichloro-methyl methyl ether and tin tetra-chloride. It adopts a pinched cone conformation, which leads to an open cavity. The two opposite aromatic rings bearing formyl groups are almost parallel, making a dihedral angle of 29.1 (2)°. The other pair of opposite rings are close to being pe...
