A synthesis of construction of cables of category 6a for infocommunication systems with improved characteristics of noise immunity is carried out. The parameters of transient pickups and total transient pickups for the proposed cable design are calculated, and the cable diameter of the initial and proposed designs is estimated. The estimation of improvement of mass-dimension parameters of a cable of a proposed design is carried out. It is shown that due to chamber (group) unearthed screening, it is possible to significantly reduce the influence characteristics and the mass-dimensional parameters of the cable.

We find the highest symmetry between the fields intrinsic to free particles (free particles having only mass, charge and spin), and show these fields symmetries and their close relationship to force and entropy. The Boltzmann Constant is equal to the natural entropy, in that it is The Planck Energy over The Planck Temperature. This completes a needed symmetry in The Bekenstein-Hawking Entropy. Upon substitution of Planck Units into The Schwarzschild Radius, we find that the mass and radius of any black hole define both the gravitational constant and the natural force. We find that the Gaussian Surface area about a particle is equal to the surface area of an equally massed black hole if we define the gravitational field of that particle to be the quotient of The Planck Force and the particles mass. By these simple substitutions we find that gravity is quantized in units of surface entropy. We also find Pythagorean Triples are resting within the dimensional parameters of Special Relativity, and show this to be the dimensional aspects of single particles observing one another, coupled with the intrinsic Hubble nature of the universe.

The study of batik in the batik centers of Giriloyo and Wijirejo Bantul is intended to develop the existing motifs of batik mbantulan and create new motifs while maintain the identity of batik mbantulan with its local-rich characteristics in Kabupaten Bantul. The development of batik mbantulan has undergone the rising and falling trend. To survive and develop artisans of batik mbantulan have to adapt themselves to the ongoing market preference through the improved characteristics of batik mbantulan. It is necessary to explore the possible existing motifs of batik mbantulan that have brought up the batik center of Giriloyo and Wijirejo have. The motifs of batik mbantulan have to be reserved in the batik products through identification, diversification, and creation of new batik mbantulan motifs, Therefore, the new designs is expected to be more competitive in batik market and create the spirit of creativity and innovativeness among the artisans of batik mbantulan in the Batik Center of Giriloyo and Wijirejo Bantul. The main obstacles that the artisans in the batik center of Giriloyo and Wijirejo have to face up is the meeting of consumers’ orders with their new motifs. The artisans are not capable enough to create new designs through the development of mbantulan motifs and prefer to work on the present and general motifs of batik Yogyakarta. The study is expected to deal with the artisans’ problem in creating new designs / motifs and improve their capacity to make new creative and innovative designs to meet consumers’ desired standard. In turn, this will lead to a better economic prospect for the artisans of batik mbantulan in the batik center of Giriloyo and Wijirejo. Key words: batik mbantulan, artisans, motifs

Introduction: Radio information transmission systems with noise-like phase-shift keyed signals based on pseudo-random sequences have potential noise immunity provided by accurately tracking the delay of the received signal in the correlation receiver. When working with moving objects, the delay of the received signal varies continuously, and the reception quality for noise-like phase-shifted signals highly depends on the synchronization system operation and on the accuracy of estimating the received signal delay by the tracking system. To ensure the required signal reception quality, it is necessary to provide an informed choice of tracking system parameters, taking into account their effects, which are the random and systematic components of the delay tracking error, on the selected noise immunity indicator.Purpose: Analyzing how the errors in tracking the delay of a received phase-shift keyed signal based on a pseudorandom sequence by the synchronization system of a radio information transmission system can affect the probability of erroneous reception of an information symbol.Results: The calculation method was used to obtain families of dependencies of the probability of erroneous reception of an information symbol on the signal-noise ratio (SNR), and the values of the random and systematic components of the delay tracking error which are normalized to the capture band of the correlation receiver. It has been shown that at a fixed SNR, the values of the random and systematic components of the delay tracking error are critical for the erroneous reception probability. In all the cases discussed, all the dependencies are characterized by a slow change of the erroneous reception probability while the synchronization errors within the area of small SNR have fixed values. As the SNR value grows, the erroneous reception probability rapidly drops. To ensure the specified signal reception quality and the reliability of the selection of information symbols and messages in a radio information transmission system with noise-like phase-manipulated signals, its synchronization system requires a joint selection of the tracking system parameters, taking into account the limitations imposed by the operating conditions and technical implementation features.Practical relevance: The obtained results can be used in noise immunity analysis of radio information transmission systems with noise-like phase-shift keyed signals in a wide range of communication conditions, and in providing technical solutions for synchronization systems ensuring the required quality of signal reception.

The article is devoted to the development of a secondary converter for measuring the speed of turbo-pump aggregates of rocket engines. The principle of the induction speed sensor is considered in the article. A method is proposed for generating output pulses from signals of induction speed sensors, which consists in the preliminary integration of the signals of the speed sensor. This method allows to increase the reliability and accuracy of the formation of signals of induction speed sensors, as well as to increase the noise immunity of the secondary converter and significantly increase the dynamic range of measuring the speed. The data of flight tests of the developed secondary converter are given.

: Tuberculosis is a disease caused by Mycobacterium tuberculosis (Mtb), affecting millions of people worldwide. The emergence of drug resistance is a major problem in the successful treatment of tuberculosis. Due to the commencement of MDR-TB (multi-drug resistance) and XDR-TB (extensively drug resistance), there is a crucial need for the development of novel anti-tubercular agents with improved characteristics such as low toxicity, enhanced inhibitory activity and short duration of treatment. In this direction, various heterocyclic compounds have been synthesized and screened against Mycobacterium tuberculosis. Among them, benzimidazole and imidazole containing derivatives found to have potential anti-tubercular activity. The present review focuses on various imidazole and benzimidazole derivatives (from 2015-2019) with their structure activity relationships in the treatment of tuberculosis.

The article investigates the problem of providing high noise immunity radar under the influence of passive and intentional interference. The purpose of radio operation of the radar is to create conditions that would impede the operation of systems and minimize its effectiveness. The main method of radio transmission is still creating (staging) interference. Modern radar systems must solve the tasks in terms of electronic suppression using, including intentional interference and under severe time constraints. It is shown that the most effective way to improve the noise immunity of radar systems designed to operate in multipoint space, including non-stationary, interference is adaptive space-time processing of the received signals, based on the angular selection of targets, due to the formation of zeros in the directional diagram in the direction of interference sources. This problem is solved by determining the accuracy of the direction finding of interference sources and is achieved by the joint operation of the antenna array and multi-channel signal processing devices, namely the separation of interference signals on different receiving channels.
