“…Slope ratios ranging from 0.8 to 1.2 were considered tolerable, whereas ratios higher than 1.2 or lower than 0.8 implied a strong matrix effect. 23 The results showed that NDMA, NMOR and NMEA presented a matrix suppression effect, NDPHA displayed a matrix enhancement effect, and the matrix effects of the other 5 analytes could be ignored. Since there was no one-to-one corresponding internal standard for the 9 target analytes, the matrix calibration working curve was used for the quantitative analysis.…”

“…High performance liquid chromatography (HPLC) with high speed, high resolution, and high sensitivity plays a pivotal role in qualitative or quantitative analysis of samples in separation science 5–9 . So far, chromatographic techniques have been proven to be one of the most practical and economic approaches for analytical and preparative separations of enantiopure substances 10,11 .…”

This study presents the development of three new chiral stationary phases. They are based on silica modified with peptides containing phenylalanine and proline. Successful analyses and characterizations were conducted using Fourier transform infrared spectra, elemental analysis, and thermogravimetric analysis. After this, the enantioselective performance of the three chiral peptide‐based columns was evaluated. The evaluation used 11 racemic compounds under normal‐phase high performance liquid chromatography mode. Optimized enantiomeric separation conditions were established. Under these conditions, the enantiomers of flurbiprofen and naproxen were successfully separated on CSP‐1 column: the separation factor of these was 1.27 and 1.21, respectively. In addition, the reproducibility of the CSP‐1 column was also investigated. The results of the investigation illustrated that the stationary phases have good reproducibility (RSD = 0.73%, n = 5).

“…We can say that this is a way of life in which you think about yourself not only in the present, but also in the future. Many scientists paid close attention to the problems of a healthy lifestyle [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. Nowadays attention should be paid to another question -what is health.…”

The article provides definitions of the following concepts: health, healthy lifestyle and physical activity. The article lists some of the principles that influence the human condition (external and internal). The main topic of the article is physical activity as one of the most important elements of a healthy lifestyle. A sociological survey was conducted in online and offline formats to identify the preferences of the population of different ages in the field of sports culture. During the analysis of the results of this study, problematic points were found and recommendations were given for maintaining and improving health through physical activity. The positive and negative aspects of the four most popular training options are reviewed and identified. The article mentions modern devices, applications and programs that motivate people to exercise and help track results. In addition, they noted the interest of the state in a healthy population, and also named some of the government's actions for the development of physical culture in the country. At the end of the article, the main results of the survey are briefly highlighted. The conclusion was made about the need for correct goal setting, search for suitable activity and motivation.
