Ab ract. Natural rubber is a valuable polymer used in a wide variety of indu ries, from tire manufactur-ing to medical products and applications in the food indu ry. The tau-sagyz rubber plant ( Scozonera tau-saghyz Lipcsh et Bosse) is one of the few plants in the world that can be used in the production of natural rubber when cultivated in culture. To increase the productivity of plants, it is necessary to e ablish factors affecting the biosynthesis of natural rubber. In our udies, the level of pigments (chlorophyll–a, b, carot-enoids) was chosen as a factor that may have a positive effect on the accumulation of rubber in the roots of S. tau-saghyz. For this purpose, samples (leaves, roots) were taken from 3 groups of plants (north, south, ea ) in the Karatau mountains of the Kurman-Tas range. The extraction of pigments from leaf samples was carried out with acetone, and the extraction of rubber from the roots was carried out with hexane. The obtained data on the content of pigments and rubber in the samples were ati ically processed using the t-te and Pearson correlation analysis. As a result, a ati ical difference in the values of pigment accumulation in leaves and rubber in roots between the 3 udied groups of plants is shown. On the other hand, a very low level of correlation was found between the accumulation of pigments in the leaves and rubber in the roots in all three groups. The obtained results reliably showed that the level of pigment accumulation in the leaves does not affect the accumulation of rubber in the roots of Tau-sagyz.
Ab ract。天然橡胶是一种有价值的聚合物，广泛应用于各种行业，从轮胎制造到医疗产品和食品工业的应用。tau-sagyz橡胶树(Scozonera tau-saghyz lippsh et Bosse)是世界上少数几种可以在培养中用于生产天然橡胶的植物之一。为了提高植物的生产力，有必要确定影响天然橡胶生物合成的因素。在我们的研究中，色素(叶绿素- a, b，类胡萝卜素)的水平可能是一个积极影响橡胶树根中橡胶积累的因素。为此，从Kurman-Tas山脉的Karatau山脉的3组植物(北、南、东)中采集样本(叶、根)。用丙酮提取叶样中的色素，用己烷提取根样中的橡胶。得到的样品中颜料和橡胶的含量数据用t-t和Pearson相关分析进行了处理。结果表明，3组植物叶片中色素积累值和根部橡胶积累值存在显著差异。另一方面，在所有三组中，发现叶片中色素的积累与根部中橡胶的积累之间的相关性非常低。所得结果可靠地表明，叶片色素积累水平不影响根中橡胶的积累。

Ab ract. This research work documents the isolation, physical and chemical characterization of essential oil of Rosa indica L. and its application in hand sanitizer. R. indica essential oil (REO) extracted from freshly illation method showed 0.057% yield. Some of the physical gravity (0.92), optical rotation (optically active), acid number (14.10), e er number (28.19), consi ency were determined in laboratory using compounds belong to eight major groups. Monoterpene alcohol represented the main characterized group (59%) followed by sesquiterpenes hydrocarbons (21.20%), phthalate e er (9.99%), aldehyde hydrocarbon (1.41%), alkyne hydrocarbons (1.21%), aromatic hydrocarbons (1.21%) and pyrozole derivative (1.21%). However, among the monoterpene alcohol, the 1-phenylethyl alcohol (13.02%); citronellol (10.01%) and 6-octen-1-ol, 3,7-dimethyl (9.55%) were found in mo abundant. Formulated hand sanitizer with REO exhibited physical and microbiological properties that were comparable with the market product. It also had pleasant scent, compatible with skin, easy to apply, and are acceptable to the users. The current udy clearly shows that REO could be utilized as a potential ingredient in hand sanitizer formulation for giving the pleasant smell, acceptable physical and microbial quality parameters.

Ab ract. Machine learning (ML) is an effective tool for analysing signals from the human brain. Machine Learning techniques provide new insight into the under anding of brain function in healthy subjects and patients with neurological and mental disorders. Here we introduce the application of machine learning to resonance imaging (fMRI) and Electroencephalography (EEG). The article provides a brief overview of the theoretical concept of machine learning and its types: supervised, unsupervised and reinforcement learning. The potential of machine learning applications in pathology is discussed. Differences between EEG and fMRI methods regarding machine learning application and an overview of the techniques employed in different research udies are reviewed. The new machine learning methods invented for analysis of brain signals in the re ing ate and during the performance of the different cognitive tasks would be useful and worth considering in other domains, not limited to medicine.
