Особенности экспресс-определения микроэлементов в лекарственных и неофицинальных растениях

Introduction. The chemical composition of plants depends on the elemental composition of the habitat, and also reflects the species and individual characteristics of the plant. Before using any plant for medicinal purposes, it is also necessary to collect as much information as possible about the elemental composition of the feedstock.Aim. Consequently, it became possible to create a method for the rapid determination of trace elements in plants using the X-Ray fluorescent method.Materials and methods. In accordance with the international intercalibration standard in the IAEA system (IAEA-433), an international standard sample NIST SRM 2976, certified by the National Institute of Standards and Technology (USA), was used to provide external quality control (QA/QC) of laboratory elemental analysis. For Zn the results of plant raw powder materials analysis by XRF (express analysis) were compared with AAS by electrothermal atomization and Zeeman background correction after microwave acid mineralizationof biomaterials. To ensure the reproducibility of the results of XRF-express analysis, it is absolutely necessary to carry out mild drying and dispersion of the plant material.Results and discussion. The results of X-ray fluorescence (XRF) analysis of the elemental composition of the fruits (fructus Anethi graveolens L.), the seeds (semina Cucurbitae pepo L., semina Menthae arvensis L., semina Cucumis sativa L., semina Kalanchoës daigremontianae) and leaves (folia Callisiae fragrantis L.) of medicinal and nonoficinal plants are presented in the article. The methods of XRF and AAS analysis have been developed for the technology of essential micoelements enrichment in of Callisiae fragrantis control leaves at different ratios of hydrogen isotopologues (D/H) in the water.Conclusion. For example, zinc(II) has demonstrated the ability to create modified plants with high content of essential microelement, up to 1.4 mg /g dry weight.Введение. Химический состав растений зависит от элементного состава среды обитания, а также отражает видовые и индивидуальные особенности растения. Перед использованием любого растения в лечебных целях, необходимо также собрать как можно более полную информацию об элементном составе исходного сырья.Цель. Следовательно, возникла возможность создания методики экспресс-определения микроэлементов в растениях методом рентгено-флуоресцентной спектрометрии.Материалы и методы. В соответствии с положением международной интеркалибрации в системе МАГАТЭ (IAEA-433) для обеспечения внешнего контроля качества (QA/QC) лабораторного элементного анализа использовали международный стандартный образец NIST SRM 2976, аттестованный Национальным институтом стандартов и технологий (США). Для цинка проведено сличение результатов анализа растительного сырья методами РФА (экспресс-анализ) и ААС с электротермической атомизацией и зеемановской коррекцией фона после микроволновой кислотной минерализации биоматериала. Для обеспечения воспроизводимости результатов РФА критически необходимо мягкое высушивание и диспергирование растительного сырья.Результаты и их обсуждение. Представлены результаты рентгено-флуоресцентного анализа (РФА) элементного состава плодов (fructus Anethi graveolentis L.), семян (semina Cucurbitae pepo L., semina Menthae arvensis L., semina Cucumis sativa L., semina Kalanchoës daigremontianae) и листьев (folia Callisiae fragrantis L.) лекарственных и неофицинальных растений. Разработанные методики РФА и ААС анализа применены для контроля технологии обогащения листьев каллизии душистой соединениями цинка при различном изотопном составе водных растворов.Заключение. Показана возможность создания металл-модифицированных растений с содержанием цинка 1,4 мг/г сухой массы

Reconstruction of spacecraft Progress attitude motion in single axis solar orientation mode by measurements of current from solar arrays

Abstract: We reconstructed the uncontrolled attitude motion of the cargo spacecraft Progress M-24M, M-25M, MC-05 и MC-06 in the single-axis solar orientation mode (so-called solar rotation). At the beginning of the oriented motion, the spacecraft rotated around the normal to solar batteries with angular rate 2.2 deg./s and the normal was directed to the Sun. The oriented motion lasted for a few orbit revolutions. The reconstruction was made using measurements of the electric current from spacecraft solar arrays. The measurement data, collected in a time interval about a few tens of minutes, were processed simultaneously by statistical methods and integration of the spacecraft attitude motion equations. As a result, the spacecraft attitude motion was reconstructed relative to the direction Earth – Sun. The investigation of the current specter showed the possibility of this way of motion reconstruction using current measurements, which were seemed to be not informative for this purpose.Note: Research direction:Theoretical and applied problems of mechanic

The real attitude motion of the spacecraft Progress M-20M in the mode of gravitational orientation

Abstract: We reconstructed the uncontrolled attitude motion of the spacecraft Progress M-20M in the mode of single-axis gravitational orientation (gravitational orientation of a rotated spacecraft). In this mode, the spacecraft rotated around its longitudinal axis with the angular rate 0.1÷0.2 deg./s, the axes being oscillated near the local vertical. The oriented motion lasted for a few orbit revolutions. The reconstruction was made using measurements of the spacecraft angular rate. The measurement data, collected in a time interval about 7 hours, were processed simultaneously by statistical methods and integration of the spacecraft attitude motion equations. The estimations of the mathematical model parameters and initial conditions of the attitude motion were obtained as a result of such processing. The results of reconstruction were checked by measurements of the electric current from the spacecraft solar batteries. We reconstructed the motion in three time intervals in February 2014. The gravitational orientation mode of Progress M-20M was realized for preparation to the experiments with convection sensor DACON-M.Note: Research direction:Theoretical and applied problems of mechanic
