Overhauser dynamic nuclear polarization (ODNP) can be used as a tool for NMR signal enhancement and happens on very short time scales.Therefore, ODNP is well suited for the measurement Musical of fast-flowing samples, even in compact magnets, which is beneficial for the real-time monitoring of chemical reactions or processes.ODNP requires the prese
In this paper, we investigate the dynamics of a discrete-time predator-prey system involving group defense.The existence and local stability of positive fixed point of the discrete Beverage Chilling Cubes dynamical system is analyzed algebraically.It is shown that the system undergoes a flip bifurcation and a Neimark-Sacker bifurcation in the inter
Solutions of atactic poly(methacrylic acid), PMAA, with molecular weights in the range of (1.6 to 3.4) x 10(5) g mol-1, and labeled with the fluorescent dyes 9-aminoacridine or Nile blue were studied by photophysical measurements as a function of solvent viscosity and polarity.The conformational behavior of the PMAA chain segments Beverage Chilling
The purpose of this study is to conduct a discussion on facilities and amenities of luxury tourism.It is a qualitative study exploring the opinions of travelers on luxury tourism.The study participants consist of 48 respondents who are members of 7 different Facebook travel groups.Data collection was carried out by posting a topic of Art for Kids d
For tracking underwater moving targets in real time, a bearings-only tracking system with a stationary double observation station was investigated.By combining the extended Kalman filter(EKF) algorithm and the unscented Kalman filter(UKF) algorithm, the bearings-only tracking system based on the EKF and UKF algorithms was simulated and compared.The
