Polymer wear debris particles undergo a thermal and mechanical (shear) cycle since their generation and therefore contain information on the friction and wear processes, while it is often difficult to draw quantitative data from them relating to transitions in tribological behaviour. Results from thermal DTA/TGA analysis and morphological pattern spectra of debris are presented and related to a transition at 180°C sliding temperatures own to hydrolysis and imidisation.

Possibility for landscape pattern modeling was demonstrated for areas characterized by active ground subsidence in the eastern part of the Middle Russian Upland (the Kursk Region) as a case study, based on the mathematical morphology of landscapes technique. Applicability of this approach for the case study area was substantiated. The investigation revealed objective difficulties caused by complex morphological pattern of the area compared with the previously proposed canonical models (in terms of the landscape science). The  simultaneous occurrence of morphometrically and physiographically different types of the depressions was considered with subsequent analysis of particular types. Significant differences in morphometric characteristics of forested and meadow depressions as well as low areas without morphologically distinct depressions (so-called “wet spots”) have been found by the application of the variance method. Correspondence of the meadow depressions mean radius sample distribution with log-normal distribution and of the “wet spots” one with normal distribution have been revealed. The forested depressions mean radius sample shows correspondence with both types of statistical distributions.

The aim of this paper is to show approaches for the quantitative evaluation of natural hazards using the remote sensing data and basing on the results of the mathematical morphology of landscape. The mathematical model of the morphological pattern for lacustrine thermokarst plains with fluvial erosion was taken for the decision of the problem in case of an asynchronous start of the thermokarst process with the continuous generation of new thermokarst depressions. The mathematical analysis of assumptions taken in the model gives us the regularities of the morphological pattern for the thermokarst plains with fluvial erosion including exponential distribution for khasyrei areas, integral-exponential distribution for lake areas, and the Poisson distribution for a quantity of either khasyreis or lakes within the key sites. Besides, analyzing the development of the territory in question by the approaches used in mathematical morphology of landscape we found out that in case of asynchronous start under very general conditions a dynamic equilibrium is established in generating thermokarst lakes and turning them into khasyreis after a long time. At the same time, the distribution density of thermokarst foci and their sizes, as well as process damage and the dimensions of khasyreis tend to some final levels specified by the expressions described above. The results obtained were empirically tested at 17 key sites. Generally, the empirical testing shows that the asynchronous start takes place within thermokarst plains with fluvial erosion at a sufficient number of sites, and the theoretically obtained regulations are valid. The regulations obtained were used for the mathematical solution of the probabilistic task for damage of a linear structure crossing the thermokarst plain with fluvial erosion.

The use of transmission electron microscopy (TEM) to support process development of advanced microelectronic devices is often challenged by a large amount of samples submitted from wafer fabrication areas and specific-spot analysis. Improving the TEM sample preparation techniques for a fast turnaround time is critical in order to provide a timely support for customers and improve the utilization of TEM. For the specific-area sample preparation, a technique which can be easily prepared with the least amount of effort is preferred. For these reasons, we have developed several techniques which have greatly facilitated the TEM sample preparation.For specific-area analysis, the use of a copper grid with a small hole is found to be very useful. With this small-hole grid technique, TEM sample preparation can be proceeded by well-established conventional methods. The sample is first polished to the area of interest, which is then carefully positioned inside the hole. This polished side is placed against the grid by epoxy Fig. 1 is an optical image of a TEM cross-section after dimpling to light transmission.

Recently, the use of refractory metal silicides as low resistivity, high temperature and high oxidation resistance gate materials in large scale integrated circuits (LSI) has become an important approach in advanced MOS process development (1). This research is a systematic study on the structure and properties of molybdenum silicide thin film and its applicability to high performance LSI fabrication.

SummaryAnimals treated in the conventional form to elicit the generalized Shwartzman reaction (gSr) by means of properly spaced injections of endotoxin develop an abrupt consumption of the plasmatic factors of the clotting mechanism, as demonstrated by the reduction of the activity of prothrombin and Ac-G (factor V). These animals show ultimatly characteristic morphological pattern: bilateral cortical necrosis of the kidney. Rabbits treated four hours after the second (‘‘provocative”) endotoxin injection with streptokinase (Varidase/Lederle) in order to activate the fibrinolytic system failed to develop the renal cortical necrosis, but their prothrombin and Ac-G (factor V) level decreased abruptly.Through indirect deduction the intravascular presence of thrombin-like activity is accepted four hours after the “provocative” endotoxin injection.
