Complex impedance spectroscopy (CIS) study was carried out using the 4- electrodes cell arrangement with NASICON membrane. The physical model developed in this work was based on own CIS characteristic of the system NASICON/solution, and it accurately described the experimental diagrams. The electron[r]
2,4-Dichlorophenoxyacetic acid is widely used in agri- culture sector. It is a systemic hormone-type selective herbicide [ 22 ], where at low concentration it can act as an auxin analogue, promoting plant growth but lethal to plants at high concentrations. Therefore, 2,4-D is also used as an herbici[r]
45 Furthermore, by examining the changes in PL spectra after annealing the samples in various ambient gas and temperatures, the type of intrinsic defects can be deduced. The quality of a ZnO sample can also be evaluated using its PL spectrum near the[r]
The objectives of the thesis: The thesis focused on the synthesis of Mn, Ce, C doped ZnO nanoparticles materials and doped ZnO with multi-layered carbon nanotube nanocomposite materials and assessed their photo-oxidative potentiality through photocatalytic reactions of methylene blue (MB) decomposit[r]
25 wt.%, while keeping the concentration of the Au pre- cursor constant, led to a formation of Au nanospheres or spherical shape (Figure 3b,3c) AuNPs with >95% (see Table 1). In the recent reports, the metal plate-like structures have been obtained[r]
EQ-5D The EQ-5D is a generic measure of HRQL which can be used for describing and valuing health states. It consists of a self-reported health state description and a visual analogue scale (VAS). The self-reported description comprises five questions referring to t[r]
Sorption of uranium (VI) from aqueous solution onto powdered corn cob has been carried out using batch and fixed-bed technique. The experimental results in batch technique were fitted well with pseudo second-order kinetics model. In the fixed bed technique, Thomas and Bohart–Adams models were evalua[r]
- A network need only be concerned with routing data between hosts, as long as the hosts agree how to direct data to processes - It is natural to organize protocols into four layer i. Network access layer: contains those protocols that provide access to a communication network[r]

like SE is completely turned off. Because SE cross sections in many alkali-metal atoms are quite large (about 10 -14 cm -2 for K, Rb, Cs) and greatly exceed those of spin-destruction collisions (by 4 orders in K, 3 orders in Rb, and 2 orders in Cs), the suppression of SE[r]
Chapter 2 - Communication processes. Chapter 2 focuses on four of the internal influences of the system''s Model of Small Group Interaction: communication, language behavior, self-disclosure, and interaction roles. This chapter concentrates on the important topic of communication. Because communicat[r]

Based on the extended Nambu-Jona–Lasinio (NJL) model with the scalar-vector eightpoint interaction [15], we consider what ultimately happens to exact chiral nuclear matter as it is heated.
