Abstract In this investigation, softwood pulp and bleached wheat straw were used as raw materials, Calcium Sulfate Whiskers (CSW) fillers. Based on the structural properties characteristics of CSW, printing paper with such whiteness, opacity, pH value, uniformity, Z-direction tensile strength surface strength, analyzed. The results showed that CSW has low solubility, high retention fiber-like a...

introduction: hot flash affects approximately 75% of women with breast cancer. those who experience hot flashes have higher rates of sleep disorders, temper and lower quality of life than women with no hot flashes. the   persent   study   was aimed to compare the effect of megestrol acetate with gabapentin on the severity of hot flashes in patients with breast cancer materials and methods: in a...

AIM To study the optical properties of human normal small intestine tissue at 476.5 nm, 488 nm, 496.5 nm, 514.5 nm, 532 nm, 808 nm wavelengths of laser irradiation. METHODS A double-integrating-sphere system, the basic principle of measuring technology of light radiation, and an optical model of biological tissues were used in the study. RESULTS The results of measurement showed that there ...

The main girders of the I-section steel-concrete composite twin girder bridge is usually connected together by frame cross bracing. When with welding, flat plates for stiffening can be used to strengthen connection ensure effective transfer forces between two. In this paper, finite element simulation method study influence plates. results show that, compared structure without stiffening, when s...

For any reduced commutative $f$-ring with identity and bounded inversion, we show that a condition which is obviously necessary for the socle of the ring to coincide with the socle of its bounded part, is actually also sufficient. The condition is that every minimal ideal of the ring consist entirely of bounded elements. It is not too stringent, and is satisfied, for instance, by rings of ...

In the 80s and early 90s. .. obviously the models were wrong. They were all underestimating what is happening now.

This paper gives a detailed account of the content analysis method developed at Queen's University Belfast to measure critical thinking during group learning, as used in our controlled comparisons between learning in face-to-face and computer conference seminars. From Garrison's 5 stages of critical thinking, and Henri's cognitive skills needed in CMC, we have developed two research instruments...

In this comment on a recent paper by Thompson-Schill et al. (1999) I argue that the authors failed to consider important empirical facts that are at variance with their favored theory of the causes of semantic category-specific deficits. I also argue that the predictions they make about fusiform gyrus activation on the basis of the interactive modality-specific hypothesis of semantic organizati...

High modulus bitumens modified by polystyrene-block-polybutadiene-block-polystyrene (SBS) with different molecular structure were investigated on dynamic shear rheometer and fluorescence microscopy to evaluate viscoelastic properties and morphology of binders. The results shows that storage modulus (G’) is obviously less than loss modulus (G”), which means viscous behaviour of bitumen is domina...
