Chemical Composition and Antioxidant Activity of Sea-Buckthorn (Hippophae rhamnoides L.) Grown in Issyk-Kul Region, Kyrgyz Republic

Aygül USUBALİYEVA | Nurzat TOTUBAYEVA

The fruit of sea-buckthorn (Hippophae rhamnoides L.) is a rich source of nutrients and phytochemicals. This study determined the chemical composition and antioxidant activity of sea-buckthorn grown in Issyk-Kul region, Kyrgyz Republic, during maturation from August to November. Three different assays [ferric reducing antioxidant power (FRAP), DPPH radical scavenging activity (DPPH), and cupric ion reducing antioxidant capacity (CUPRAC)] were used to determine the antioxidant activity of sea-buckthorn fruits. Sea-buckthorn fruits had a sugar content of 6.57-8.08 g/100g, a dietary fiber content ...Более

Impact of Kara-Keche lignite mining on the Kara-Keche River water composition and properties = Влияние разработки Кара-Кечинского буроугольного месторождения на состав и свойства вод реки Кара-Кече

Kanatbek KOCOBAYEV | Nurzat TOTUBAYEVA | Nurzat ŞAYKİYEVA

On the evidence of the earlier research findings, as well as the full-scale and lab-scale test data of 2019–2020, this article describes the ecological situation at Kara-Keche lignite field being developed by five mining companies in the Jumgal district of the Naryn Region in the Kyrgyz Republic. It is found that the field development proceeds with insufficient adherence to legal documents and has a considerable adverse influence on the environment and water bodies. Many large-volume refuse dumps have no isolation from natural water bodies, which ends with acute pollution of the latter. Contam ...Более

Identifying Geogenic and Anthropogenic Aluminum Pollution on Different Spatial Distributions and Removal of Natural Waters and Soil in Canakkale, Turkey

Mehmet KOBYA

The Çanakkale–Kirazlı region (Turkey) is enriched with minerals, especially aluminum (Al), which dangerously get transported into aquatic media due to several mining and geological activities in recent years. In this study, Al and other potentially toxic metals (PTMs) including B, Ba, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, Si, and Zn, in both water and soil samples, were measured for quality determination. Selected metals were also analyzed by the enrichment factor (EF), the geoaccumulation index (Igeo), the contamination factor (CF), and the pollution load index (PLI) to evaluate both water and soil ...Более

Bioremediation approaches for oil contaminated soils in extremely high-mountainous conditions

Nurzat TOTUBAYEVA | Ciyde TOKPAEVA | Canarbek İZAKOV | Mirlan MOLDOBAYEV

Development of methods for bioremediation of soils contaminated with petroleum products is one of the most urgent tasks of our time. This task is more difficult to perform in high-mountainous landscapes, at an altitude of more than 4 000 m a.s.l. Moreover, these high-mountain ecosystems are the most vulnerable to various kinds of anthropogenic impacts, and therefore the relevance of bioremediation is obvious. The research was conducted in the high-altitude ecosystems of the Kyrgyz Republic at the Kumtor mine. In this study was carried out on the bioremediation of oil contaminated soil using bi ...Более

Study of relations between chemical, colour and fluorescence properties of raw and dried meat powders of cow and yak (Bos grunniens)

Cıldızay ÖZBEKOVA | Asılbek KULMIRZAYEV

Gluteus medius, Longissimus thoracis, and Semitendinosus muscles from the cow and yak (Bos grunniens) reared in the Kyrgyz Republic were dried by convective (hot air) drying and freeze drying. The dried muscles were grinded into fine powders and along with raw muscles were evaluated for water activity (aW), chemical composition (moisture, fat, protein), colour characteristics (L, a, and b values), fluorescence of intrinsic fluorophores (tryptophan, vitamin A, and riboflavin). Processing of measured data tables using common components and specific weights analysis (CCSWA) showed close relations ...Более

Synthesis of poly(Oak bark) particles from oak bark extract and its utilization as a drug carrier material

Nahit AKTAŞ

As oak bark extract includes pharmaceutically meaningful precious biochemicals such as vanillic acid, quercetin, catechin, caffeic acid, gallic acid, ferulic acid, syringic acid, chlorogenic acid, q-coumaric and protocatechuic acid, the present study focuses on synthesizing polymeric particles from that extract while keeping their targeted natural bioactivity. In this study, due to the bioavailability of oak bark extracts, poly(Oak bark)water extract (p(OB)w), poly(Oak bark)ethanol extract (p(OB)e) and poly(Oak bark)water-ethanol extract (p(OB)we) particles were synthesized using redox polymer ...Более

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. ...Более

Investigation of Battery Energy Storage Utilization Strategies for Reducing the Unscheduled Power Flows in the Interconnection Lines Caused by Multiple Electric Arc Furnace Operations

Özgül SALOR-DURNA

In this paper, utilization strategies for battery energy storage systems (BESS) are assessed in order to reduce the unscheduled power flows in the interconnection lines caused by multiple electric arc furnace operations in Turkey. Turkish electricity network is synchronously connected to the European Network of Transmission System Operators for Electricity (ENTSO-E) via 3 EHV transmission lines. Extensive amount of intermittent loads like electric arc furnaces (EAF) in the electricity network cause unscheduled power deviations at the intertie lines hence Area Control Error (ACE) performance de ...Более

Cyber crime risk awareness in Kyrgyz Republic

Rita İSMAİLOVA | Gülşat MUHAMETJANOVA

In this paper we present the information security awareness rate of students in Kyrgyz Republic, where there is a rapid pace of formation and development of the information society. The survey was conducted with a sample of 172 students from different departments of the university. Our research study showed that despite the huge number of reports about computer crimes in the web, the knowledge about cybercrime is quite low and students are mostly not aware of many aspects of computer crime. Analysis was done to determine dependence of information security awareness rate on computer literacy ra ...Более
