Certain regularities of the kinetics of drying of moist materials

A method for calculating the kinetics of drying under the conditions of continuous variation in the Rehbinder number in the period of decreasing drying rate is considered. __________ Translated from Inzhenerno-Fizicheskii Zhurnal, Vol. 80, No. 4, pp. 143–146, July–August, 2007.     

Testing the type GT-10S (SGT 700) gas turbine units at the Sochi thermal power station

We present the results from thermal tests of the GT-10S gas-turbine units produced by Siemens, operating as part of PGU-39 power-generating units Nos. 1 and 2 at the Sochi thermal power station, which are the first ones of this type in Russia.     

Fluorescent Amines as a New Tool for Study of Siliceous Sponges

Siliceous sponges (Hexactinellida and Demospongiae classes) are aquatic invertebrates which are important both for marine and freshwater ecology and also as the source of biologically active compounds. The sponge skeleton consists of spicules - needle-like or branched composite structures based on silicon dioxide. Mechanisms of silicon assimilation and synthesis of high-ordered glass-like structures at ambient temperatures by sponges are intriguing for biologists, chemists and nanotechnologists. Fluorescent amines are in-vivo dyes that stain growing siliceous frustules of diatom algae so the use of these agents for the sponge study was attempted. We found that cultivation of the Lubomirskia baicalensis (Pallas, 1773) sponge in the presence of fluorescent tracers of biosilica - N¹,N³,N³-trimethyl-N¹-(7-nitro-2,1,3- benzoxadiazol-4-yl)propane-1,3-diamine and N¹,N³-dime thyl-N¹-[3-(dimethylamino)propyl]-N³-(7-nitro-2,1,3-benz oxadiazo-4yl)propane-1,3-diamine results in the staining of growing siliceous spicules. This finding shows that amine dyes accompany silicon from the environment to sponges spicules which opens a new way to study of silicon assimilation by sponges. Fluorescent staining of the growing spicules following with the confocal microscopy can be a powerful tool for morphological studies, revealing information about the dynamics of spiculogenesis and for bio-fabrication of new fluorescent materials.     

Organization of the infosphere for a large-scale research-and-production complex as an object of the information industry

This paper presents a model of an infosphere that is designed for the military–industrial complex as a large-scale research-and-production complex using the system method. The tasks of development and modernization of the infosphere in the military–industrial sector are formulated. A draft concept of a modernized infosphere that is designed for the military–industrial complex is presented.     

Optimization Problems with Interval Uncertainty: Branch and Bound Method

An order on a set of centered intervals is introduced and is proved to be linear. An optimization problem is formulated over a set of centered intervals. The branch and bound method is proposed and substantiated to solve this problem. A number of theorems that substantiate estimates in the branch and bound method are proved.
