Students' knowledge of discrete mathematics was tested using two methods – 'close-type' test and 'inwriting'. 'In-writing' was independently evaluated by two different teachers. These results were statistically analyzed in this article.doi:10.15388/lmr.2007.24210A. KrylovasO. SubocN. KosarevaLietuvos matematikos rinkinys
Sayqal and Saber determined SER in pharmaceuticals by simple and developed spectrophotometric methods. The methods relay on forming ion-pair complexes between SER and different reagents. SER was interacted, in buffer solution of 2.0–8.0 pH, with methyl orange (MO), methyl green (MG), methyl bl...
Considering the cost of soil sampling and analysis, dense and repeated sampling is usually impractical. Mapping the spatial distribution of soil pollution requires spatial interpolation methods. Consequently, interpolation techniques such as inverse distance weighting (IDW), kriging and Spline have been ...
Analysis of average postoperative pain in relation to pain-related interference with mood and activity indicated pain categories of NRS 0–2, mild; 3–4, moderate; and 5–10, severe pain. Conclusions Three of the four methods identified a treatment threshold of average pain of NRS≥4. This ...

Samples were parallel processed from the two methods and proteins were analyzed with label-free quantitative MS. Over 700 and 1200 proteins were quantified in FFPE and OCT samples, respectively. Multivariate analysis indicates that the preservation method is the main source of variation, but also ...
Due to the strong correlations of PV-CW/CL and PV-GTP, we included PV in cluster analysis for the first time. As a result of the variety of included samples, measurement means and statistical methods, different categories and proportional distribution were obtained in different papers. In ...
Stock analysis is the evaluation of a particular trading instrument, an investment sector, or the market as a whole. Stock analysts attempt to determine the future activity of an instrument, sector, or market.
Statistical analysis was performed using XLSTAT 2016. Principal component analysis was conducted, assuming the data can be described on a lower dimension. Paired t-tests were conducted after checking for normal distribution of the data set. 3. Results 3.1. qPCR Cross-Contamination During an infecti...
Methods We investigated the biodistribution of SARS-CoV-2 among different tissues of inpatients with coronavirus disease 2019 (COVID-19) diagnosed based on symptoms and radiology and confirmed by SARS-CoV-2 detection. This study was approved by the ethics commissions of the participating hospitals, ...
