The desanding in heavy oil has been indispensable to oilfield exploration and production. The methodology of natural sedimentation is considered the effective way in oilfield, as a consequence of the best separation effect, a large handling capacity, low energy consumption, simple operation and low-carbon green. This paper did some research on natural sedimentation separation characteristics in the desanding of heavy oil, through experimental study, in order to test setting time and viscosity of various kinds of size in heavy oil, which indicates the relationship of viscosity, size and sedimentation rate. Not only make sure the relationship of setting time, viscosity and size, but also the boundary between floating zone and stable region in the desanding of heavy oil, Based on these data which has an important guiding role to make sure the time that natural sedimentation takes for oil-water-sand, desanding properties of heavy oil and separator size.

At present, there are much more researches on the ordinary concrete composite slab, and that on the lightweight aggregate concrete composite slab are relatively less. In this paper, the shear-bond behavior of lightweight aggregate concrete composite slab, with the profiled steel sheet YX-76-344-688, which is commonly used in China is studied. Base on experiments, the cracks developing process and its regularities of distribution, the bonding and slipping between profiled sheeting and concrete, the relationship of load and mid-span deflection, ultimate bearing capacity etc. are studied.

Theoretical Overview

The article deals with the correlation of indicators of psychoticism with such personal characteristics as temperament and anxiety of the individual. A brief theoretical overview of the topi of temperament and psychoticism is given. The basic interrelationships of the concepts of social adaptation, temperament and anxiety were considered. The main trends of their interrelation are highlighted. In the experimental study, differences were found between groups with high psychoticism and medium-low psychoticism. There are differences in the factors: reactive anxiety and confidence. The indicators of neuroticism are in the zone of uncertainty.

28th meeting 11 January 1930 Dr. B.N. Lebedevsky. On the question of the relationship of the nose with the genital area. The literature of the issue is reported. An experimental study involved 20 rats in which the use of galvanocaustics in the nose managed to pervert the sexual cycle controlled by the Allen method. Studying the mechanism of transmission of irritation from the nose to the genitals is the task of further research. - Debate: profffK. R. Viktorov, V. K. Trutnev and Dr. Wolfson, Lopatina.

Calcium sulfoaluminate cement (CSA) is a low-carbon cementitious material that significantly reduces alkalinity and produces calcium hydroxide-free (CH-free) matrix environment in comparison to ordinary Portland cement (OPC). It might be, however, less efficient towards the passivation of steel in concrete and further investigation before widespread adoption is required. In this project, scanning electron microscopy/energy dispersive X-ray spectroscopy (SEM/EDX) on polished samples was employed to provide the interfacial characterization of steel reinforced CSA concrete and study the relationship of interfacial quality and corrosion resistance of the embedded steel. The galvanostatic polarization behavior indicates that the steel embedded in CSA concrete remains passive for 28 days in absence of Cl− ions and carbonation. Microstructure analysis has shown that there is an Al-enriched layer at interfacial zone in CSA concrete with the main hydration product of AH3, which is also alkaline and is expected to improve the steel passivity. Furthermore, the interfacial zone has markedly reduced porosity compared to the bulk matrix, which leads to reduced possibility of current flow between anode and cathode and therefore improves the corrosion resistance of the embedded reinforcement.
