RESEARCH ANALYSIS TO SUBSTANTIATE THE TERMS OF GEOMETRIC PARAMETERS IMPROVEMENT OF TIMBER-CARRYING FOREST ROADS

RBC agglutination by lectins represents an interactive balance between the attractive (bridging) force due to lectin binding on cell surfaces and disaggregating forces, such as membrane stiffness and electrostatic charge repulsion (1). During agglutination, critical geometric parameters of cell contour and intercellular distance reflect the magnitude of these interactive forces and the size of the bridging macromolecule (2). Valid ultrastructural measurements of these geometric parameters from agglutinated RBC's require preservation with minimal cell distortion. As chemical fixation may adversely influence RBC geometric properties (3), we used chemical fixation and cryofixation (rapid freezing followed by freeze-substitution) as a comparative approach to examine these parameters from RBC agglutinated with Ulex I lectin.

One of the most important diagnostic problems multilayer dielectric materials and coatings is the development of methods for quantitative interpretation of the checkout results their electrophysical and geometric parameters. The results of a study of the potential informativeness of the multi-frequency radio wave method of surface electromagnetic waves during reconstruction of the electrophysical and geometric parameters of multilayer dielectric coatings are presented. The simulation model is presented that makes it possible to evaluate of the accuracy of reconstruction of the electrophysical and geometric parameters of multilayer dielectric coatings. The model takes into account the values of the electrophysical and geometric parameters of the coating, the noise level in the measurement data and the measurement bandwidth. The results of simulation and experimental investigations of reconstruction of the structure of relative permittivitties and thicknesses of single-layer and double-layer dielectric coatings with different thicknesses, with different values of the standard deviation (RMS) of the noise level in the measured attenuation coefficients of the surface slow electromagnetic wave are presented. Coatings based on the following materials were investigated: polymethyl methacrylate, F-4D PTFE, RO3010. The accuracy of reconstruction of the electrophysical parameters of the layers decreases with an increase in the number of evaluated parameters and an increase in the noise level. The accuracy of the estimates of the electrophysical parameters of the layers also decreases with a decrease in their relative permittivity and thickness. The results of experimental studies confirm the adequacy of the developed simulation model. The presented model allows for a specific measuring complex that implements the multi-frequency radio wave method of surface electromagnetic waves, to quantify the potential possibilities for the accuracy of reconstruction of the electrophysical and geometric parameters of multilayer dielectric materials and coatings. Experimental investigations and simulation results of a multilayer dielectric coating demonstrated the theoretical capabilities gained relative error permittivity and thickness of the individual layers with relative error not greater than 10 %, with a measurement bandwidth of 1 GHz and RMS of noise level 0,003–0,004.

Research Analysis

AbstractPresidential Election in 2019 has become the most interesting executive election throughout Indonesia's political history. People likely separated, either Jokowi’s or Prabowo’s stronghold. Then it can be assumed, when someone, not a Jokowi’s stronghold he or she certainly within Prabowo’s stronghold. The issue that was brought up in the presidential election campaign, sensitively related to religion, communist ideology, China’s employer, and any other issues. On the other side, politics identity also enlivened the presidential election’s campaign in 2019. Normative Yuridis method used in this research, which was supported by primary and secondary data sourced from either literature and social phenomenon sources as well. The research analysis concluded that political identity has become a part of the political campaign in Indonesia as well as in other countries. The differences came as the inevitability that should not be avoided but should be faced wisely. Finally, it must be distinguished between political identity with the politicization of identity clearly.Keywords. Identity Politics, 2019 Presidential Election
