In this paper, effects of nano-CaCO3 on compressive strength and Microstructure of high strength concrete in standard curing temperature(21±1°C) and low curing temperature(6.5±1°C) was studied. In order to improve the early strength of the concrete in low temperature, the early strength agent calcium nitrite was added into. Test results indicated that 0.5% dosage of nano-CaCO3 could inhibit the effect of calcium nitrite as early strength agent, but 1% and 2% dosage of nano-CaCO3 could improve the strength of the concrete by 13% and 18% in standard curing temperature and by 17% and 14% in low curing temperature at the age of 3days. According to the XRD spectrum, with the dosage up to 1% to 2%, nano-CaCO3 can change the orientation index significantly, leading to the improvement of strength of concrete both in standard curing temperature and low curing temperature.

Cellulose nanocrystals (CNCs) were wet-spun in a coagulation bath for the fabrication of microfilaments, and the effect of sodium alginate (AL) addition on the wet-spinnability and properties of the microcomposite filament was investigated. The CNC suspension exhibited excellent wet-spinnability in calcium chloride (CaCl2) solution, and the addition of AL in CNC suspension resulted in the enhancement of the wet-spinnability of CNCs. As the AL content increased from 3% to 10%, the average diameter of the microcomposite filament decreased, and its tensile properties deteriorated. The increased spinning rate caused an increase in the orientation index of CNCs, resulting in an improvement in the tensile properties of the microcomposite filament.

In 1984 Hogan, Hogan, and Busch defined service-orientation as “the disposition to be helpful, thoughtful, considerate, and cooperative” (p. 167). As a measure they developed the Service Orientation Index, a 92-item true-false questionnaire. The present study tested whether a biographical inventory could also be used to measure the construct of service-orientation. Subjects were given the biographical inventory and the Index to predict their service-oriented performance in a simulated interaction with a customer. Scores on the Service orientation Index were significantly correlated with scores on two biographical scales, Sociability and the Need to make a good impression. The correlations, .24 and .27, were as high as those obtained by Hogan, et al. The Index scores were also significantly correlated with the criterion. Subjects with high scores on Sociability and the Need to make a good impression had the highest ratings on service-orientation. Implications for research and applications of these results are mentioned.

Lignocellulose nanofibrils (LCNFs) with different lignin contents were prepared using choline chloride (ChCl)/lactic acid (LA), deep eutectic solvent (DES) pretreatment, and subsequent mechanical defibrillation. The LCNFs had a diameter of 15.3–18.2 nm, which was similar to the diameter of commercial pure cellulose nanofibrils (PCNFs). The LCNFs and PCNFs were wet-spun in CaCl2 solution for filament fabrication. The addition of sodium alginate (AL) significantly improved the wet-spinnability of the LCNFs. As the AL content increased, the average diameter of the composite filaments increased, and the orientation index decreased. The increase in AL content improved the wet-spinnability of CNFs but deteriorated the tensile properties. The increase in the spinning rate resulted in an increase in the orientation index, which improved the tensile strength and elastic modulus.

ABSTRACTFactors such as the type of aggregate, the addition of silica fume, and the roughness of the aggregate surface, which influence the orientation index of Ca(OH)2 crystals in the interface layer, are discussed, based on the experimental results of Maso [3] and the author. Then, a hypothesis about the mechanism of this orientation is proposed, involving the Ca(OH)2 crystal structure and the principles of physical chemistry of surfaces.From this hypothesis, it is suggested that the reduction of the orientation index of Ca(OH)2 crystals when silica fume is added is due to physical aspects other than the large water requirement of silica fume. The same is also true when the aggregate surface is rough.

Orientation Index

On the basis of a reinterpretation of the International Sexuality Description Project (ISDP) data, we suggest that findings are consistent with the view that human reproductive behaviour is largely under social control. Behaviours associated with a high Sociosexual Orientation Index (SOI) may be part of a progressive change in reproductive behaviour initiated by the dispersal of kin that occurs as societies modernize.
