Nurzat ŞAYKİYEVA | Kubat KEMELOV | Mirlan MOLDOBAYEV | Canıl İSKAKOVA | Mustafa DOLAZ

This study aims to evaluate and reuse defective products and cotton wastes resulting from factories producing socks in Bishkek, Kyrgyzstan, in order to solve the issues related to their disposal. For this purpose, microcrystalline cellulose (MCC) was obtained after isolating the cellulose from these wastes by treating them with sulfuric acid solutions. Then, under constant NaOH and monochloroacetic acid (MCA), CMC with the highest DS value of (0.65) was synthesized at 65 degrees C for 2 hours. When the reaction time was increased (3, 4 and 5 hours) at the same temperature, the DS value decreas ...More

Ecological aspects in the use of soil enzymes as indicators of anthropogenic soil pollution

Nurzat TOTUBAYEVA

In the contemporary era, with rapid industrial growth and urbanisation, analysing the impact of human activities on soil enzyme activity becomes crucial. The purpose of this study is to assess the influence of anthropogenic pollution on enzyme activity in soil. Research on enzyme activity levels in the soil in the city of Kara-Balta, Chuy Region, Kyrgyz Republic, was conducted using biochemical analyses and specific enzymatic tests. The results revealed significant diversity in catalase activity in different soil samples. Some samples exhibited high activity, while others showed low activity. ...More

Development of mountain tourism and general tourism in the Kyrgyz Republic = Развитие горного и общего туризма в Кыргызской Республике

Kanatbek KOCOBAYEV

Рассказано об истории, текущем состоянии и проблемах туристической отрасли Кыргызстана. Туристический потенциал страны — огромный, однако экономическая отдача от него пока незначительная. В настоящее время наибольшее развитие получили два направления — рекреационный и культурно-познавательный туризм. Рекреационный туризм обеспечивает 90–95 % объема всех туристических услуг и базируется на потенциале оз. Иссык-Куль. Культурно-познавательное направление связано с уникальной природой и самобытной культурой кочевого народа гор. Большие перспективы развития имеет также экотуризм. - Ключевые слова: ...More

Regular Flow Field Sparse Processing and Blue Finance of Ocean City Research Based on GIS System

In order to explore the development path of blue finance in ocean cities, this paper combines GIS to conduct blue finance research in ocean cities, draws on the traditional direct visualization method of point icons, and uses arrow symbols to render vector flow field data. Moreover, this paper uses GIS means to perform statistical analysis on flow field data, studies the adaptive sparse algorithm of flow field data spatial structure based on GIS, and proposes a program implementation method for regular flow field sparse processing suitable for the general flow of the sparse algorithm. The expe ...More

Management of Power Marketing Audit Work Based on Tobit Model and Big Data Technology

In order to improve the management effect of power marketing audit work, this paper combines big data technology to carry out related data processing, changes the management mode of traditional power marketing audit work, analyzes the overall process and characteristics of the current power marketing audit case selection, and designs an audit system. Moreover, this paper builds a data warehouse based on data mining technology and realizes the process of automatic generation of the index system. In addition, this paper chooses the Tobit model proposed by Tobin, which is a restricted dependent v ...More
