The work is devoted to the problems of manufacturing thinwalled parts of the aviation industry and instrument engineering on modern numerical control machines. The main reason of defects of such products -loss of dimensional accuracy is revealed. The reason for this is the elastic deformation of the workpiece during milling. A mathematical model for calculating the elastic pressing of a thin wall during milling is proposed. The method of checking the adequacy of the developed model with the help of engineering analysis system is presented. The minimum set of geometrical parameters of the processed element and the cutting tool necessary for search of the rational cutting mode was defined. A new approach to automation of this process present through the evaluation of all possible solutions. The calculation of the rational cutting mode was made taking into account the conditions of rigidity of the workpiece. Conclusions on the efficiency of the developed technique are made.

Search Stage

New approach of complex uncertainties analysis at the exploration stage of the field is considered not only for geological properties but also for reservoir engineering, including the uncertainty of type of hydrocarbons saturation. The method shown in the work is based on the probabilistic method of HIIP estimation which is followed by probabilistic reservoir engineering uncertainties assessment in production profiles calculation.

AbstractA widely used tool in studying quasi-monoperiodic processes is the O–C diagram. This paper deals with the application of this diagram in minor planet studies. The main difference between our approach and the classical O–C diagram is that we transform the epoch (=time) dependence into the geocentric longitude domain. We outline a rotation modelling using this modified O–C and illustrate the abilities with detailed error analysis. The primary assumption, that the monotonity and the shape of this diagram is (almost) independent of the geometry of the asteroids is discussed and tested. The monotonity enables an unambiguous distinction between the prograde and retrograde rotation, thus the four-fold (or in some cases the two-fold) ambiguities can be avoided. This turned out to be the main advantage of the O–C examination. As an extension to the theoretical work, we present some preliminary results on 1727 Mette based on new CCD observations.

The Cross

Previously we reported that tannic acid is a very effective fixative for proteins including polypeptides. Especially, in the cross section of microtubules, thirteen submits in A-tubule and eleven in B-tubule could be observed very clearly. An elastic fiber could be demonstrated very clearly, as an electron opaque, homogeneous fiber. However, tannic acid did not penetrate into the deep portion of the tissue-block. So we tried Catechin. This shows almost the same chemical natures as that of proteins, as tannic acid. Moreover, we thought that catechin should have two active-reaction sites, one is phenol,and the other is catechole. Catechole site should react with osmium, to make Os- black. Phenol-site should react with peroxidase existing perhydroxide.

Immunoelectron microscopy of neoplastic lymphoma cells is valuable for precise localization of surface antigens and identification of cell types. We have developed a new approach in which the immunohistochemical staining can be evaluated prior to embedding for EM and desired area subsequently selected for ultrathin sectioning.A freshly prepared lymphoma cell suspension is spun onto polylysine hydrobromide- coated glass slides by cytocentrifugation and immediately fixed without air drying in polylysine paraformaldehyde (PLP) fixative. After rinsing in PBS, slides are stained by a 3-step immunoperoxidase method. Cell monolayer is then fixed in buffered 3% glutaraldehyde prior to DAB reaction. After the DAB reaction step, wet monolayers can be examined under LM for presence of brown reaction product and selected monolayers then processed by routine methods for EM and embedded with the Chien Re-embedding Mold. After the polymerization, the epoxy blocks are easily separated from the glass slides by heatingon a 100°C hot plate for 20 seconds.
