2. Oscillation of nonlinear three-dimensional difference systems with delays
- Creator:
- Schmeidel, Ewa
- Format:
- bez média and svazek
- Type:
- model:article and TEXT
- Subject:
- difference equation, three-dimensional nonlinear system, and oscillation
- Language:
- English
- Description:
- In this paper the three-dimensional nonlinear difference system ∆xn = anf(yn−l ), ∆yn = bng(zn−m), ∆zn = δcnh(xn−k), is investigated. Sufficient conditions under which the system is oscillatory or almost oscillatory are presented.

- Subject:
- allophycocyanin, dithiothreitol, energy transfer, N-succinimidyl-3-(2-pyridyldithio)propionate, phycocyanin, phycoerythrocyanin, and rod-core complex (αβ)6PCLRC27 (αβ)3APCLC8.9
- Language:
- Multiple languages
- Description:
- The model conjugates phycocyanin-allophycocyanin (C-PC-APC) and phycoerythrocyanin-phycocyanin-allophycocyanin (PEC-C-PC-APC) were synthesized by using a heterobifunctional coupling reagent N-succinimidyl-3-(2-pyridyldithio)propionate. The rod-core complex (αβ)6 PCLRC 27(αβ)3 APCLC 8.9 and phycobilisomes were separated from Anabaena variabilis. Energy transfer features for the conjugates and the complexes were compared. The absorption and fluorescence emission spectra indicated that the linker-peptides mediate interaction of phycobiliproteins and prompt energy transfer. The energy transfer in the conjugates was detected by fluorescence emission spectra and confirmed by the addition of dithiothreitol. The conjugates may be used as models for studying the energy transfer mechanism in phycobilisomes. and Jiquan Zhao ... [et al.].

- Description:
- Počítačové modelování biomolekul je zaměřeno na studium struktury, dynamiky a vzájemných interakcí nukleových kyselin, proteinů a buněčných membrán, zkoumání katalytického účinku enzymů, racionální návrh struktury nových léků atd. K dispozici je celá škála metod - bioinformatika, klasické molekulárně-dynamické (MD) simulace, kvantově-chemické ab initio výpočty, popř. kombinované QM/MM přístupy. Mezi softwarovými balíky většinou existuje i víceméně plnohodnotná freewarová alternativa., Computer modeling of biomolecules is aimed at studying the structure, dynamics and interaction of nucleic acids, proteins and cell membranes, examining the catalytic effect of enzymes, rational drug design etc. There is a whole range of methods - bioinformatics, classical molecular dynamic (MD) simulations, quantum-chemical ab initio calculations, or combined QM/MM approaches. Among the software packages there is usually more of less full-featured freeware alternatives., Ivan Barvík., and Obsahuje bibliografii

5. Water surface topology of supercritical junction flow
- Creator:

- Format:
- bez média and svazek
- Type:
- model:article and TEXT
- Subject:
- junction, hydraulic experimention, standing wave, supercritical flow, and flow patterns
- Language:
- Slovak
- Description:
- The complexity of flow conditions at junctions amplifies significantly with supercritical flow. It is a pronounced three-dimensional two-phased flow phenomenon, where standing waves with non-stationary water surface are formed. To analyse the hydrodynamic conditions at an asymmetric right-angled junction with incoming supercritical flows at Froude numbers between 2 and 12, an experimental approach was used. For a phenomenological determination of the relations between the integral parameters of incoming flows and the characteristics of standing waves at the junction area, water surface topographies for 168 scenarios at the junction were measured using non-intrusive measurement techniques. The new, phenomenologically derived equations allow for determination of location, height and extent of the main standing waves at the junction. Research results give important information on the processes and their magnitude for engineering applications.
