The Deflection Angle

A device is proposed for measuring the surface velocity of water, the use of which is based on the use of a new informative parameter — the deflection angle of the movable float sensor (together with the guide slide) from the vertical in the direction of the dynamic axis of the flow, allowing you to simply and reliably measure the surface velocity of water.

In the work the technology of radio-frequency identification of objects with inductive coupling is considered, using passive electric oscillating circuits tuned to fixed frequencies from the working frequency range as identification features of the object. The choice of the primary measuring transducer and the informative parameter is based on the results of the analysis of the system of inductively coupled active and passive electric oscillation circuits, known from the theory of radio engineering circuits. The parameters of the measuring transducer ensuring the fulfillment of the requirements for identification and localization of objects specified by technological conditions are substantiated. Factors that are potentially dangerous with respect to reducing the information reliability of the measuring transducer are considered, as well as the possibility of reducing their influence to a minimum. The problems of experimental research are formulated. It is shown that the analysis can be performed by software discrete adjustment of the primary measuring transducer and the generator feeding it. In this case, the task of increasing the speed is targeted at decreasing the duration of the step of tuning the primary measuring transducer. The required reliability of object identification is achieved by: ensuring high stability of the frequencies of the generator supplying the primary measuring transducer; accuracy and stability of tuning of the primary measuring transducer to the frequencies of the supplying generator; protection of the primary measuring transducer from the influence of interference generated by external sources and other measuring converters of the object identification system (electromagnetic compatibility of the object identification system); sufficient magnitude of the response of the primary measuring transducer to the introduction of passive electrical oscillation circuits; sufficient frequency tuning interval for passive electric oscillation circuits; accuracy and stability of tuning of passive electric oscillation circuits; stability of the detection threshold relative to the initial level of the informative parameter. Electromagnetic compatibility of measuring transducers, whose sensing elements are in the zone of mutual influence, is provided by synchronizing the operation of measuring transducers with shunting of inactive sensors, screening, mutual orientation and spacing of sensing elements.

Abstract Purpose: Conventional MRI based on contrast enhancement and T2/FLAIR is often not sufficient in differentiating grade II from grade III and grade III from grade IV diffuse gliomas. Here we assessed advanced metabolic imaging using two well characterized PET tracers, namely 18F-FDG and 11C-Methionine.Methods: In this prospective study, 39 patients were enrolled with diffuse gliomas of grades II, III or IV underwent dynamic [18F]-FDF-PET and [11C]-Methionine. The first minutes were taken into accountResults: The use of 11C- Methionine provided significant differences between the different histologic subgroups with a higher number of parameters than did the use of 18 F-FDG. The most informative parameter is T/Np (T/N at the peak of the first maximum) with 11C- Methionine.Conclusion: The study of the first minute passage of 18F-FDG and/or 11C- Methionine through the tumor and healthy tissues in brain gliomas could not only allow improving the identification of the different glioma grades, but also to shorten the time spent by the patients under the camera. In case of using one tracer, methionine still would be the best choice. Otherwise, the use of 18F-FDG and SUVр (SUV at the peak of the first maximum) would provide results likely comparable to methionine T/N index.

В статье представлены результаты морфо-биологических наблюдений и биохимических показателей декоративных корневищных многолетников рода Iris L. семейства Iridaceae, произрастающих в условиях Кузбасского ботанического сада. Установлена видоспецифичность по продолжительности вегетации и уровню накопления антиоксидантов в листьях декоративных травянистых многолетников: I. aphylla>I. halophila>I. chrysographes>I. ruthenica>I. pseudacorus. Выявленные перестройки в функционировании антиоксидантной системы ирисов позволяют рассматривать их, как приспособительные и защитные реакции, направленные на их выживание и декоративные качества в окружающей среде. Исследуемые показатели можно использовать в качестве информативного параметра для оценки состояния растений в интродукции. Here we present the results of morphological and biological observations and biochemical parameters of decorative rhizome perennials of the genus Iris L. of the Iridaceae family, growing in the Kuzbass Botanical Garden. We assess the duration of the growing season in relation to particular species. We also estimate the level of antioxidants in the leaves of decorative herbaceous perennials: I. aphylla> I. halophila> I. chrysographis> I. ruthenica> I. pseudacorus. The revealed rearrangements in the functioning of the antioxidant system of irises make it possible to consider them as adaptive and protective reactions aimed at their survival and preservation of decorative qualities. The studied indicators can be used as an informative parameter for assessing plants' state in the introduction.

This article shows the possibility of using the shock impulse method widely used in the building industry for the control of above-ground concrete structures in relation to elements of underground geocomposite protective constructions. As a result of experimental studies performed in the laboratory on various mortar mixtures that harden, it was established that there is a close correlation relationship between two data arrays: the values of the shock pulse duration and the uniaxial compression strength. The reliability of the obtained regression equations is in the range of 0.82 - 0.9. This shows the possibility of using the shock pulse method in the new version, with the previously unused informative parameter - the shock pulse duration for assessing the strength of mortar mixes that harden, which are widely used to create geocomposite constructions.
