This study was carried out to determine the influence of milking season on amino acid (AA) profile and chemical composition of milk samples from Kyrgyz native breed mares under traditional pasture conditions. Milk samples were collected monthly from May to August 2014 from mares grazing at 2,200 m above sea level. The AA composition was determined by precolumn derivatization with diethyl ethoxymethylenemalonate in HPLC and 18 AA were determined in mare milk. The analytical parameters of linearity (0.01–4 μg/mL), precision of the method (0.26–4.88% relative standard deviation), derivatization p ...Более
The natural methods of uniform topology for construction of Wallman compactifications and Wallman realcompactifications are developed. Results on partial order and relations of dimensions in the lattice of compactifications are presented. The construction of the maximal compactification among compactifications of X with fixed realcompactification is given. -

The purpose of this study is to determine levels of technological proficiency among university students to see if they should be characterized as “digital natives.” For this purpose, rather than using types and frequency of technology use to characterize a digital native, the Digital Native Assessment Scale (DNAS) developed by Teo (2013) was employed. This scale has an established reliability and validity measure. It measures several factors (e.g., grew up with technology, comfortable with multi-tasking, reliant on graphics for communication, thrive on instant gratifications and rewards, etc.) ...Более
