  • Mesh saliency has been widely considered as the measure of visual importance of certain parts of 3D geometries, distinguishable from their surroundings, with respect to human visual perception. This work is based on the use of convolutional neural networks to extract saliency maps fo large and dense 3D scanned models. The network is trained with saliency maps constructed with a fusion spectral and geometrical analysis generated measures. Extensive evaluation studies carried out, include visual perception evaluation, simplification and compression use cases. As a result, they verify the superiority of our approach as compared to other state-of-theart approaches. Furthermore, performance experiments indicate that CNN-based saliency extraction method is much faster in large and dense geometries allowing its application in low-latency and energy-efficient systems.

  • The author analyzes the evolution of the formation of the concept of national security and ways to strengthen the technological security of the state, assesses the features of the impact of the development of modern technologies on the national security of the state, discusses the issues of ensuring national security and stability of the state in the context of the development of new technologies. Against the background of the development of modern technologies in the world, there is a steady increase in the dependence of states on global technological and external commodity expansion. In these conditions, the issues of strengthening technological safety and scientific potential, preventing the obsolescence of the material and technical production base are cardinally in demand and innovative categories. The author pays special attention to the development of technological security of the state in modern conditions. Technological security is an important element of the national security system and is positioned as an integral part of economic state security, which forms the material basis for supporting various types of security. The author also emphasizes that ensuring national security, being a paramount task, is a multi-component, complex, but extremely important and necessary component of any sovereign state. An absolute necessity is the priority of the internal interests of society and the state. That is why it is important at a methodological level to structure all aspects of the state’s national security policy through the prism of its strategic development. Given the needs and capabilities of the country, national security should be directed to the future. When implementing a program to protect national interests, it is necessary to take into account the dynamic nature of the world situation and forecast situations from various angles.

  • Liver diseases have become a major global health challenge and may be triggered by several toxic chemicals, which include chemotherapeutic agents, thioacetamide, H2O2, certain antibiotics, excessive alcohol consumption, and pathogenic microbes. Hence, safeguarding a healthy liver is vital for good health and well-being. Chicory (Cichorium intybus) belongs to Asteraceae Family and is considered very important medicinal plant in this direction. The present study deals evaluation methanolic extracts of Chicory plant for a period of 45 days at the following dose levels; 50 and 75 mg/kg body weight/day, orally respectively. The activities were studied by assaying aspartate transaminase (AST), alanine transaminase (ALT), alkaline phosphatase (ALP), total and direct bilirubin (TB)and (DB), total protein (TP), albumin (Alb), catalase (CAT) and Superoxide dismutases (SOD). The methanolic extract of Cichorium intybus at dose 75 mg/kg body weight/day has the highest effectiveness against H2O2- induced hepatotoxicity.

  • A method is described for the inductively coupled plasma optical emission spectrometric (ICP-OES) determination of rare earth elements (REE), yttrium (Y), thorium (Th) and phosphorus (P) in monazite samples. Sample preparation was carried out by fuming with sulphuric acid followed by fluoride fusion of the remaining residue. The method was validated using the single laboratory approach by assessment of analytical performance characteristics like specificity, linearity, range, accuracy and precision. Spectral interferences were observed in the case of some heavy REE (Ho,Er,Tm) by light REE (Nd) and correction factors were deduced and applied. The limit of quantification, instrument linearity and the method range were evaluated. Relative standard deviation (RSD) values ranging from 2.6 to 10.2 % were obtained for repeatability studies and RSD values ranging from 1.7 to 11.1% for intra-lab reproducibility studies. Accuracy was established by application to a monazite certified reference material (CRM) and also through comparison of results obtained by present method with those obtained by an alternate method. The validation results were compliant with the acceptance criteria for the various parameters assessed. A simple procedure has been described for the estimation of associated measurement uncertainty using the GUM “bottom-up” modelling approach and results presented in this paper. The validated method was applied to the determination of REE, Y, Th and P in some monazite samples from India.

  • In the present study, addition of nitroso group at position 1 of 2-aminoanthraquinone (1) to yield 2-amino-1-nitroanthraquinone (2) was carried out by the reaction of compound (1) with sodium nitrite in water. Compound (2) was used as starting material to produce many new naphtho[2,3-f] quinoxaline-dione, trione, naphtho-pyrazole quinoxaline-dione, anthra-triazine-dione, naphtho-thiazole quinoxaline-dione and anthrabenzo-triazepine-dione derivatives by elimination of one molecule of water as an initial reaction step. The reacting moieties were nitroso and amino function groups to yield a series of compounds. The structures of the products were determined by elemental mass, IR and 1H NMR analysis and the adopted method is efficient to prepare a series of compounds and could possibly be used for the synthesis of new compounds.

  • Packaging in bread-making industry is one of priorities to satisfy the peculiar requirements of freshness in bread. A suitable packaging material allows for both rapid heat exchange with the environment and water vapour evaporation in order to prevent condensation inside the bread package. The effectiveness of some storage media/packaging materials in preventing bread spoilage under ambient temperature was studied. Bread staling, microbiological stability and organoleptic changes were evaluated as a function of storage time. The functional properties (water and oil absorption capacities and water oil absorption indices) of the bread were estimated .The water absorption capacity (WAC) of bread was in the range of 144-221 g/100 g sample, while the oil absorption capacity (OAC) range was 113-132 g/100 g. Water Oil Absorption Capacity (WOAI) for each of the packaging materials was < 2.0, which indicates the lipophilic nature. All the bread slices stored under different media/packaging materials, except perforated bowl and transparent plastic bowl exhibited sensory scores of 2.5 and above. Microbial growth manifested in bread kept in perforated and transparent plastic containers compared to the bread kept in cellophane and aluminum plate. This study clearly shows differences in the rates of staling, microbial stability and physical/chemical changes at different storage conditions.
