Одним из важнейших факторов, исключающих возникновение дефектов типа пор, расслоений, участков с неполной полимеризацией связующего в формуемой высоконагруженной полимерной композитной конструкции, является управляемость процесса во всем объеме композита. Для обеспечения однородности процесса полимеризации связующего предложен метод многокритериальной оптимизации процесса на основе математической модели, связывающей процессы распространения тепла и кинетики полимеризации. Система связанных уравнений процесса, учитывающая экзотермическое тепло, выделяемое при полимеризации термореактивного связующего, изменение теплоемкости и теплопроводности композита при фазовых переходах от жидкого к гелеобразному и, далее, к твердому состоянию, точную геометрию технологической системы, включая прессформу, а также интенсивность тепловыделения независимо управляемых нагревателей, реализована в виде конечноэлементной модели. Предложенный метод синтеза закона оптимального управления нагревателями, использующий метод множеств Парето, проиллюстрирован на примере полимеризации разностенной композитной конструкции, формуемой из стеклопластика.

This article considers the causes of halitosis and methods of the diagnosis. Halitosis, syndrome of bad breath caused by pathological condition of the oral cavity or internal organs and systems, has a significant impact on the patient's social life. Analysis of the composition of exhaled air may become a promising way to diagnose halitosis, as the direct relationship between the compositions of molecules of oxygen, carbon dioxide, nitrogen oxides, ammonia etc. and the causes of halitosis were found. The article's authors review and analysis the methods of measurement of qualitative and quantitative composition of exhaled air. The most common methods include the use of electrochemical, optical sensors, infrared spectrometers and mass spectrometers. The latter method is positioned as the most optimal method of analysis of exhaled air due to its high accuracy, selectivity and sensitivity. The authors' portable mass spectrometer being developed is represented. At this stage it can detect traces of oxygen and carbon dioxide, which inject into the device through the capillary system or membrane one, in gas samples in real-time mode.

In this work we have investigated the structure of individual single-walled and multi-walled carbon nanotubes by high-resolution electron microscopy and electron diffraction. To grow carbon nanotubes we used a catalytic chemical vapor deposition method. It was shown, that this synthesis protocol gave in general single-walled and double-walled carbon nanotubes with a high level of crystallinity. The diameters of the nanotubes were in the range 1.5 - 7 nm. We also observed that there was a certain level of amorphous carbon deposited on the nanotube surface during the growth. In this work we also present the structure analysis of the double-walled carbon nanotube by means of electron diffraction. We show that the structural date derived from electron microscopy and electron diffraction agree within the experimental error.
