Kuzbass Botanical Garden climate characteristics and the state of the environment

The characteristic of a number of parameters variability of the Kuzbass Botanical Garden climate are studied for the period from 1966 to 2020.An indirect assessment of the climate based on the climate biological efficiency index is given. The analysis of the long-term dynamics of the selected parameters is carried out, the main temporal patterns in their distribution are revealed. As initial materials, air temperature and precipitation daily data for the period 1966-2020.

Zero- to Ultralow-Field NMR Spectroscopy of Small Biomolecules

<p>Nuclear magnetic resonance (NMR) spectroscopy is a well-established analytical technique used to study chemicals and their transformations. However, high-eld NMR spectroscopy necessitates advanced infrastructure and even cryogen-free benchtop NMR spectrometers cannot be readily assembled from commercially available components. We demonstrate construction of a portable zero-field NMR spectrometer employing a commercially available magnetometer and investigate its applications in analytical chemistry. In particular, <i>J</i>-spectra of small representative biomolecules [¹³C]-formic acid, [1-¹³C]-glycine, [2,3-¹³C]-fumarate, and [1-¹³C]-D-glucose were acquired and an approach relying on the presence of a transverse magnetic eld during the detection was investigated for relaxometry purposes. We found that water relaxation time strongly depends on the concentration of dissolved D-glucose in the range of 1-10 mM suggesting opportunities for indirect assessment of glucose concentration in aqueous solutions. Extending analytical capabilities of zero-field NMR to aqueous solutions of simple biomolecules (aminoacids, sugars and metabolites) and relaxation studies of aqueous solutions of glucose highlight the analytical potential of non-invasive and portable ZULF NMR sensors for applications outside of research laboratories.</p>

An Indirect Evaluation of Program Educational Objectives and Student Outcomes for Engineering Programs: A Case Study

Outcome and objective assessment is a method for determining whether students and graduates have learned, have retained, and can apply what they have been taught. Assessment plans have to include a statement of educational objectives, measurements of attainment of the objectives, and use of the assessment results for continuous improvement. In this paper, the experience of the Electrical Engineering program at Al-Imam Mohammad Ibn Saud Islamic University is used as an example of how an indirect assessment method is established and implemented. Many surveys have been used and contributed to the numerical analysis for the indirect assessment of the program outcomes and achievements. The indirect assessment results indicate that the target levels are achieved for all the seven program outcomes and the three objectives that have been considered.
