Crystal transformation of dicalcium silicate (2CaO•SiO2, C2S) has influences on the microstructure, hydraulicity, and grindability of cement clinker. The transformation of β-C2S to γ-C2S can destroy the clinker nodule integrity by volume expansion due to the low density of the γ-phase. It can be used to pulverize cement clinkers for saving grinding energy, but the hydraulicity of γ-C2S is lower than β-C2S. Quantitative control of C2S crystal transformation could balance the energy saving and hydraulicity. The influences of sintering temperatures, cooling methods and chemical impurities on the transformation were investigated. The results show that the appropriate sintering temperature of γ-C2S was 1250～1500 °C, and the rate of cooling should not be higher than 500 °C/min to guarantee β-C2S transform to γ-C2S. Chemical impurities (Na2O, P2O5, B2O3, Cr2O3 and K2O) were stabilizers of β-C2S, which could prevent β-C2S transforming to γ-C2S. The stability effect was related to their concentrations. The characteristic concentrations of Na2O, P2O5, B2O3, Cr2O3 and K2O were approximately 1.2%, 0.3%, 0.3%, 1.0% and 1.5%, respectively. Above these concentrations, most of β-C2S could be stabilized rather than transforming to γ-C2S. In “transition zone”, C2S crystal transformation could be controlled quantitatively by adjusting the stabilizer concentration.

Block Volume

Model tests were done with dolosse having the same shape and volume, but with different block densities, to determine the effect of block density on stability and to check whether the theoretical third-power relationship between block volume and relative block density is valid. From these tests it can be concluded that the higher the density of the block material the greater the stability becomes. Although the individual scatter is appreciable, the average results indicate that the stability of dolosse is inversely proportional to a power of about 2,3 of the relative density, which is significantly less than the theoretical power of 3. Model tests were also carried out on dolosse having the same mass and volume but with different waist-to-height ratios to determine the effect of waist-to-height ratio on the stability of a dolos armour. From the results of these tests it can be concluded that the stability of the armour decreases with increasing waist thickness, particularly for relatively high waist ratios.

Abstract Casing treatment (CT) has proven to be an effective way to enhance stability, and has a very important role in enhancing the stability of the compressor. Researchers have made great achievements and progress in the study of single-type CT structure, but less research on combined-type CT structure. In this paper, the isolated rotor of a high-load axial-flow compressor is taken as the research object, and the numerical simulation method is used to study the enhancing stability mechanism of the combined-type casing treatment (ASCT) by combining the axial slot casing treatment (ASC) and the self-circulating casing treatment (SCT). The study found that the reasonable choice of the ASCT scheme can make the enhancing stability effect of the ASCT higher than that of the single-type CT structure scheme. Through detailed quantitative analysis of the rotor’s internal flow field, it was found that ASC and SCT can suction the airflow downstream of the rotor passage, and then spray it into the main flow from the upstream of the rotor passage, and the blade tip blockage is reduced, the flow capacity of the blade tip passage is improved, and the rotor stability is enhanced by suppressing tip clearance leakage flow. The ASCT has both the spraying effect of the ASC and the SCT, and has the best improvement effect on the flow blockage zone in the rotor passage, and the obtained enhancing stability effect is also best. In addition, the circulation and re-injection of the airflow after CT has aggravated the flow blending loss in the blade tip zone, which has reduced the rotor efficiency. The ASCT has both the characteristics of the effect of the ASC and the SCT on the rotor efficiency, resulting in a large reduction in the rotor efficiency after using the ASCT.

To solve the existent stability difficulties in the long term storage of the silver nanoparticle hydrocolloids (AgNPs) , this paper makes a comprehensive investigation on the effects of different synthetic methods which influence the stability of AgNPs. The controlled AgNPs are prepared by two kinds of precursors: silver diamminohydroxide ([Ag (NH3)2]OH ) and silver nitrate (AgNO3 ) respectively precursors;in addition the stability of the AgNPs hydrocolloid is studied by UV-vis; A discovery was found after contrast :the particle sizes of the [Ag (NH3)2]OH precursor based AgNPs hydrocolloid are more uniformed,well controlled and of better dispersibility.this kind of AgNPs exhibits higher stability compared to the AgNO3 precursor based AgNPs hydrocolloid.

The thermal degradation of linalool-chemotype Cinnamomum osmophloeum leaf essential oil and the stability effect of microencapsulation of leaf essential oil with β-cyclodextrin were studied. After thermal degradation of linalool-chemotype leaf essential oil, degraded compounds including β-myrcene, cis-ocimene and trans-ocimene, were formed through the dehydroxylation of linalool; and ene cyclization also occurs to linalool and its dehydroxylated products to form the compounds such as limonene, terpinolene and α-terpinene. The optimal microencapsulation conditions of leaf essential oil microcapsules were at a leaf essential oil to the β-cyclodextrin ratio of 15:85 and with a solvent ratio (ethanol to water) of 1:5. The maximum yield of leaf essential oil microencapsulated with β-cyclodextrin was 96.5%. According to results from the accelerated dry-heat aging test, β-cyclodextrin was fairly stable at 105 °C, and microencapsulation with β-cyclodextrin can efficiently slow down the emission of linalool-chemotype C. osmophloeum leaf essential oil.

Social peace is an asset to every society. Its absence endangers the well-being and the safety of the population and the stability of states. In order to better understand the interdependencies of poverty, social peace and migration pressure the authors introduce the model of the “Edgeworth-Cube” which is an extension of the classical Edgeworth Box model by one dimension. This new dimension can either be interpreted as “aggression” (which reduces “social peace” for others) or as “migration pressure” (which results from a worldwide heterogeneous distribution of wealth), and this new dimension is modelled as a non-budget-constrained unilateral immaterial good. The “Edgeworth-Cube” also differentiates vital (essential) goods from normal (non-essential) goods. By focusing on extremely imbalanced endowments and by formal mathematical modeling the authors show in their approach that applying behavioral pressure (i.e. aggression or migration pressure) has an existential economic value for the poor on the one hand. On the other hand, the authors show that transfer payments have a systemically limited potential to keep aggression and migration pressure at bay.

Conti: One of the main conclusions of the Wolf-Rayet symposium in Buenos Aires was that Wolf-Rayet stars are evolutionary products of massive objects. Some questions:–Do hot helium-rich stars, that are not Wolf-Rayet stars, exist?–What about the stability of helium rich stars of large mass? We know a helium rich star of ∼40 MO. Has the stability something to do with the wind?–Ring nebulae and bubbles : this seems to be a much more common phenomenon than we thought of some years age.–What is the origin of the subtypes? This is important to find a possible matching of scenarios to subtypes.
