Random numbers are a crucial component of any encryption activity in modern cryptography. Quantum Random Number Generators (QRNGs) produce truly random output strings to replace pseudo-random ones. In this research, the author’s team centered on investigating and scrutinizing the design of a QRNG utilizing optical methods tailored to meet cryptographic standards.

TiO2 has strong photocatalytic activity, which can oxidize and decompose impurities on surfaces and in the air. Therefore, TiO2 is used as an additive in the self-cleaning coating and paint industries. In this work, SiO2 is used in the TiO2/SiO2 mixture as the nucleus to homogenize the dispersion components. TiO2 and SiO2 nanoparticles are synthesized by the sol-gel method combined with ultrasound that suits the size range of 10-30 nm.

The efficient synthesis of 12-substituted-3,4,4a,5,12,12a-hexahydrobenzo[b]acridine-1,6,11(2H)-triones starting from 2-amino-1,4-naphthoquinone, 1,3-cyclohexanedione, and different (hetero)aromatic aldehydes was developed. These reactions were carried out in acetic acid under microwave irradiation in the presence of p-toluenesulfonic acid as catalyst. The structure of the newly synthesized compounds were confirmed employing spectroscopic data as well as elemental analysis. The plausible mechanism of these three-component domino reactions was also described.

The methanol extracts as well as some compounds from this plant exhibited anti-inflammatory, antimicrobial activity, antioxidant, hepatoprotective and anti-cancer effect, and antiosteoporotic. On going to search for bioactive components from the Vietnamese plant, this paper reported the isolation of seven phenolic compounds including one new from the aerial parts of A. ilicifolius. The cytotoxic activity of the isolates against two cancer cell lines (HepG2 and SK-LU1) were also screened and reported herein.

The melting points of the complexes were >350oC, indicating high thermal stability. Cu-Zn-containing complex showed the least binding energy against the three proteins. The bioactivity scores of the complexes were between -0.50 and 0.0. Against A549 Cu-Zn, Co-Zn and Fe-Zn containing complexes showed potential activity. Against MCF-7, Fe-Cu containing complex had IC50 of 53.5 whereas Co-Zn containing complex was active against HepG2. Three complexes were active against S. aureus in the tested range.

UML has become a standard modeling language because of its programming language independence. UML is used to design software and information systems in the form of common UML diagrams: use case diagrams, class diagrams, sequence diagrams, state diagrams, activity diagrams, component diagrams, and deployment diagrams. The research used case diagrams to design the land price information system functions and class diagrams to design the land price database. Therefore, we use UML language to create a land price information system and land price database for Dan Phuong district, Hanoi city.

This article substantiates the need to strategize food markets’ development in the region as components of the region's reproduction cycle of food products by using supply chain management. The authors suggest two approaches in terms of this development in the region. Within the framework of the product-territorial approach, strategies have been defined for the development of markets for individual food products in order to activate internal sources of forming product supply.

The authors used prospective estimates of revenue and expenses for ordinary activities, obtained on the basis of a multiplicative trend-seasonal model to predict the profit of an agricultural enterprise. The study draws attention to the fact that the classical decomposition of the trend-seasonal model into trend, seasonal and random components is possible and convenient for forecasting the financial performance of an agricultural enterprise that has seasonality in crop and livestock production.
