Food packaging requirements of gas barrier and self-cleaning are satisfied with the use bio-renewable cellulose, chitosan, silica, sunflower oil.
The study focuses on analyzing the factors affecting employee commitment to restaurants in Thanh Hoa, based development and application of measurement scales suitable for current situation context. research sample consists 186 responses from customers who have experienced dining at Hoa City, eligible analysis using Smart PLS 4.0 statistical software PLS-SEM model. results show that five influence commitment, following order impact: (3) Salary, bonuses, benefits; (5) Promotion opportunities;...
Abstract Rourea oligophlebia (Connaraceae) plant has been traditionally used for the treatment of bleeding and bone fractures. Chemical study on ethyl acetate extract stem , collected at Ben En National Park, Thanh Hoa province, have led to isolation five compounds including friedelin ( 1 ), friedelinol 2 coniferyl alcohol 3 7 α ‐hydroxyl‐3 β ‐sistosterol 4 ) scopoletin 5 ). The structures these elucidated by NMR, MS spectroscopic data comparison with reported literatures. This is first...
Forming reading competence is a very important issue for children 5-6 years old when preparing to enter grade 1. Language development in kindergarten focuses on the formation and of children's competence. At 5 - 6 old, structure must first be determined. With this concept approaching problem, article clarifying preschool by analyzing manifestation, components, behavioral indicators proposing
In this work, we proposed a highly efficient sonoelectrochemical technique for the straightforward synthesis of TiO2 nanoparticles at mild temperature 60 oC under an atmosphere environment. The as-prepared materials were then applied photocatalytic removal Cr(VI) in aqueous solution. possess anatase crystalline phase with particle size about 6.5 nm and superior surface area 202.85 m2/g. Its reduction 5 ppm UVA irradiation showed efficiency 99.3% after 180 min. These obtained results provide...
The development of children at preschool age is a very important stage for the human being. Therefore, seeding "reading culture" right and practical direction to lay foundation everyone's reading culture, same time, towards learning society in context digital transformation. In this article, we develop standard book familiarization skills based on identifying components ability. performance departmental competencies evaluated components, behavioral indicators quality criteria. Those are...
Some different catalysts, such as organic and inorganic bases basic ionic liquids were used for synthesis of 2-amino-4H-pyran-3-carbonitriles containing propargyl group. Efficient catalysts these substances estimated. The structures the obtained compounds confirmed by modern spectroscopic methods (IR, 1H NMR, 13C NMR).
Some ethyl 6-amino-5-cyano-2-methyl-4-aryl-4H-pyran-3-carboxylates were synthesized by reaction of using three-component included acetoacetate, malononitrile and appropriate substituted benzaldehydes. The role different catalysts was examined, including organic inorganic substances ionic liquids. 2-amino-4H-pyran-3-carbonitriles converted reacting with chloroacetyl chloride. structures the obtained compounds confirmed modern spectroscopic methods (IR, 1H NMR, 13C NMR).
Layout of temporary facilities on a construction site is essential to enhance productivity and safety. It complex issue due the unique nature construction. This problem validated as an NP-hard one challenging problems in field management. In this paper, we proposed hybrid algorithm, named topt-aiNet, solve layout by combining aiNet algorithm with Tabu search. Experimental results showed that outperformed stateof-the-art ones.

Vietnam's education system is undergoing a comprehensive renovation in the direction of competence development, which also educational development trend times. Preschool does not have task teaching children to read and write, but determining goal forming reading one important tasks language for preschool children, especially at end kindergarten when begin change main activity from playing learning. Research results on current situation 5-6-year-old some provinces northern mountainous region...
For the first time, expansion grade of graphite was studied through effect flake size. The result shown larger size exhibits a higher grade. In addition, more expanded material, specific surface area can be obtained. synthesized graphites were used for adsorption methylene blue. with highest displayed capacity due to its area.
