In this article, the issues of education and upbringing, which are always considered relevant, are analyzed. These analyzes were made on the basis of the works of Eastern scholars on education and training, as well as knowledge and enlightenment. In addition, the importance of the issue of education and training today has been shown.
Nizamiddin Mir Alisher Navoi, who is the "shams ul-millat" of the Turkic peoples, is a word artist who has enriched the treasure of world literature with his sensitive poetry, his great "Khamsa", and his rich scientific heritage dedicated to various fields of science. This great genius, who used more than 26,000 words of vocabulary in his creative heritage, has been surprising the people of the world for more than five centuries with the deep philosophical observation in his works, the vastness of the sea of eloquence in his poetic heritage.
A large role in choosing a name is played by various goals and intentions, social and cultural values, and traditions. However, as long as this cultural activity is not carried out on the basis of logic, the personal names of the nation will remain prone to primitive content and illogical forms and forms. The article analyzes the names given by Uzbeks as a result of different attitudes towards children. Instead of a conclusion, it is said that it is necessary to raise the consciousness of the nation from such vices to the political level.
"Prey-prey" relationship has been formed since the time when there was a diversity of living things in nature. Various living organisms have been identified that feed on plants along with their pests and spread certain diseases, and the amount of phytophages is limited due to these natural pests. The cabbage butterfly is one of the common pests known to everyone, and it is distinguished by its high density in areas where cabbage is grown and where there are wild cabbages. Until now, this species is important as a pest of cabbage, but during the next decades, it was observed that it developed and caused certain damage in other cruciferous plants. Cabbage butterfly in the imago state feeds on plant nectar and does not harm plants, but their caterpillars have a gnawing mouth apparatus and cause severe damage.
The article focuses on the bioecological characteristics of aphids, which are considered a pest of fruit trees. In this article, the seasonal development of E. lanigerum aphids in the conditions of the specified area, the life cycle, i.e., the characteristics of the aphids, such as the period of exiting the winter stage depending on the ambient temperature, have been separately researched. This type of aphid significantly damages the development of trees, yield and quality of fruits. They feed on the bodies of apples, young branches, leaves, plant parts, absorbing carbohydrates. Many young shoots infected with aphids stop growing and dry up. The fruits of the harvested trees are small in appearance and contain little sugar. In the conditions of the Fergana Valley, 4 types of aphids (Aphis pomi De Geer, Eriosoma lanigerium, Dezaphis affinis, Dezaphis Mali.) are pests of apples. In the course of our research, it was once again confirmed that E. lanigerium sap is second only to A. pomi in terms of causing damage in valley conditions. Taking into account the above situation, the life cycle, biology and ecological features of Eriosoma Lanigerum are noted.
The article presents information on the distribution and biology of important invasive species in the vegetable-police fields in Central Fergana. Distribution and biology of important invasive species distributed in the conditions of Central Fergana in vegetable-melon crop fields were studied, and phenological calendars were developed. Development, reproduction, growth of invasive species Agriotes sputator (planting season clicker), Leptinotarsa decemlineata (Colorado potato beetle), Phthorimaea operculella (potato moth), Tuta absoluta (tomato moth) and Delia platura (onion fly) damage to plants and stages of development were analyzed.
In the article, sodium and potassium salts of naphthenic acids are used as emulsifiers in the production of emulsion oils and demulsifiers in the dehydration of oils, calcium and aluminum naphthenates, as well as calcium and zinc salts are used as thickeners in the preparation of the consistency of lubricating oils. lead, cobalt and manganese naphthenates are used as dispersant additives in motor oils. The possibility of using it as a drying agent in the paint and varnish industry, and copper and cobalt salts - in the production of colored asphalt is shown.
The article presents the results of the extraction of oil from safflower seeds and the study of its acid composition. Methyl esters of fatty acids were analyzed by gas chromatography on an Agilent 6890 N instrument with a flame ionization detector, and the qualitative and quantitative composition of fatty acids in seed oil of two samples of Carthamus tinctorius L. was studied.
The article describes the results of the spread of invasive pest insects that seriously affect the vegetable-police agrocenoses across Central Fergana. During the research, it was found that Colorado potato beetle (Leptinotarsa decemlineata), tomato moth (Tuta absoluta), mulberry moth (Glyphodes pyloalis) and onion fly (Delia platura) entered as adventive species and became dominant in the valley.
Экстракцию проводили 0,2 н. раствором гидроксида натрия в соотношении 1:10 на магнитной мешалке. Клеточный дебрис удаляли центрифугированием при 6000 об/мин в течение 30 мин на охлаждаемой центрифуге РС-6. Полученный прозрачный супернатант (осажденный раствор) осаждали сульфатом аммония при перемешивании на магнитной мешалке. Полученный экстракт оставляли в холодильнике на 16 часов для образования белка.
For environmental education and environmental education in Chemistry, some environmental issues should be used appropriately. They serve as an excellent tool in organizing classes for future chemistry teachers.
The article reveals the chemical composition of turnip: carbohydrates (glucose, fructose), pectins, vitamins. The products of polysaccharide hydrolysis were studied by paper chromatography
