Der Einfluß der chemischen Zusammensetzung des Schweißgutes auf die Heißrißanfälligkeit von UP-Stahlschweißgut wird unter Beachtung metallurgischer Gesichtspunkte ermittelt. Kohlenstoff und Nickel erhöhen durch die Begünstigung der austenitischen Erstarrung die Heißrißanfälligkeit, und das Zusammenwirken von Kohlenstoff und Nickel kann durch ein Kohlenstoffäquivalent erfaßt werden. Heißrisse können bei sehr geringem Schwefelgehalt auftreten, wenn das Schweißgut vollständig austenitisch erstarrt. Mit zunehmendem Mangangehalt nimmt die Heißrißanfälligkeit des Schweißguts beim Einlagenschweißen ab, beim Mehrlagenschweißen ist jedoch der Einfluß von Mangan auf die Heißrißanfälligkeit gering. Vanadin setzt die Heißrißanfälligkeit des Schweißguts herab. 相似文献

TimeBank evolution as a community resource for TimeML parsing 总被引:1,自引:1,他引:0

TimeBank is the only reference corpus for TimeML, an expressive language for annotating complex temporal information. It is
a rich resource for a broad range of research into various aspects of the expression of time and temporally related events.
This paper traces the development of TimeBank from its initial—and somewhat noisy—version (1.1) to a substantially revised
release (1.2), now available via the Linguistic Data Consortium. The development path is motivated by the encouraging empirical
results of TimeML-compliant annotators developed on the basis of TimeBank 1.1, and is informed by a detailed study of the
characteristics of that initial release, which guides a clean-up process turning TimeBank 1.2 into a consistent and robust
community resource.

Rie?an gave in Rie?an (2004) [9] an axiomatic characterization of a probability on IFS-events and proved in Rie?an (2006) [10] a representation theorem for it. In Ren?ová [9], Ren?ová introduced the notions of additive φ-probability and strongly additive φ-probability and gave a representation theorem for strongly additive φ-probabilities.In this paper we give a generalization of the axiomatic characterization given by Rie?an in Rie?an (2006) [10]; from this, the representation theorem for strongly additive φ-probabilities will follow. 相似文献

It has been drawing much attention that type 2 diabetes mellitus is closely associated with increased incidence of numerous cancers and their poor prognosis. Consequently, malignancy has been recently recognized as one of diabetic complications in addition to various conventional complications. Furthermore, it is well known that the prevalence of renal cell carcinoma (RCC) is drastically increased in hemodialysis (HD) patients. Therefore, screening of RCCs in HD patients is a very important and urgent issue as there are no highly sensitive tumor markers for RCCs. Monochrome superb microvascular imaging (mSMI) is a relatively new Doppler ultrasound technique and is useful especially when evaluating very slow blood flow state, because this allows for imaging microvessels with low velocity in the absence of a contrast agent. Thus, mSMI might be also useful when contrast enhancement is not obvious on CT and/or contrast-enhanced ultrasonography using perflubutane or contrast agents are contraindicated. Moreover, it has been reported that mSMI could effectively detect vascularity of renal malignant tumor than benign renal mass in nondialysis patients. We propose that mSMI of ultrasonography could become one of the very useful methods for detecting RCCs at an early stage with high sensitivity in HD patients. 相似文献

In view of the expected cryptanalysis (of both classical and quantum adversaries), it is important to find alternatives for currently used cryptographic primitives. In the past years, several authenticated key exchange protocols (AKE) that base their security on presumably quantum hard problems, such as lattice-based AKEs, were proposed. Since very different proposals for generic AKEs as well as direct AKEs, i.e., protocols directly based on lattice-based problems without additional authentication, exist, the performance of lattice-based AKEs is not evaluated and compared thoroughly. In particular, it is an open question whether the direct constructions are more efficient than generic approaches as it is often the case for other primitives. In this paper, we fill this gap. We compare existing lattice-based authenticated key exchange protocols, generic and direct. Therefore, we first find the most efficient suitable primitives to instantiate the generic protocols. Afterward, we choose parameters for each AKE yielding approximately 100 or 192 bits of security. We implement all protocols using the same libraries and compare the resulting performance. We find that our instantiation of the AKE by Peikert (PQCrypto, 2014) is the most efficient lattice-based AKE. Particularly, it is faster than the direct AKE by Zhang et al. (EUROCRYPT, 2015). 相似文献

Effectiveness of lipase in detergency was studied using three test soils (lard, artificial sebum, and olive oil) on a woven
cotton fabric. Distribution of oily soil on fabrics was determined for three different treatments (unwashed, washed with detergent
without lipase, and washed with detergent plus lipase). Osmium tetroxide was used to label lipid soil for analysis in the
scanning electron microscope. Both longitudinal and cross-sectional backscattered electron images for unwashed samples showed
that soil was present on surfaces of the cotton fibers and in interfiber spaces of the yarn bundle. Lard soiled samples had
large deposits on the fabric surfaces, while artificial sebum and olive oil appeared more uniformly distributed throughout
the textile. Oil was deposited in the interfiber capillaries of the yarn bundle and in the crenulation, secondary walls, and
lumen of the fibers. Energy dispersive X-ray microanalysis was used to determine relative concentrations of oil at selected
morphological locations within the fiber structure and at the fiber surface. Soil distributions within the fibrous structures
differed with type of soil and laundry treatment. Backscattered electron images dramatically demonstrated the effect of lipase
on cleaning. After washing with detergent plus lipase, yarn surfaces had much less residual soil; residual soil that remained
was in the irregularities of the cotton fiber surfaces. Concentrations of oil in the secondary walls, crenulations, lumen,
and the fiber surfaces were lower after lipase treatment for all three soils. While washing with detergent removed soil from
the yarn and fiber surfaces and the crenulation of the cotton fiber, only the samples washed with detergent plus lipase had
lower concentrations of soils within the secondary wall and lumen of the cotton fibers. Fabrics soiled with olive oil and
washed with detergent plus lipase had the lowest concentrations of residual soil across the textile structure; the residual
soil observed was mainly in the irregularities on the fiber surfaces. 相似文献

The antioxidative effects of rosemary and grape-seed extracts spiked in human plasma were examined using the thiobarbituric acid (TBA) method. The TBA values of plasma spiked with reagents to generate reactive oxygen species, such as singlet oxygen ((1)O(2)), hydroxyl radicals ((·)OH), peroxynitrite (ONOO(-)), and superoxide anions (O(2)(·-)), were measured by a flow injection analysis method with fluorescence (FL) detection. TBA values obtained by the addition of 50 mg/mL of rosemary extracts for (1)O(2), (·)OH, ONOO(-), and O(2)(·-) increased to 964 ± 65%, 1063 ± 61%, 758 ± 78%, and 698 ± 41%, respectively (n = 3, P < 0.01), whereas the values with 1 mg/mL of grape-seed extracts or tocopherol decreased (40.2 - 66.3%). Furthermore, the antioxidative effects of rosemary extract in rat plasma, spiked with reagents to generate (·)OH, were examined by high-performance liquid chromatography with FL detection. No peak, other than TBA-malondialdehyde, could be detected using wavelengths of 532 (λ(ex)) and 553 nm (λ(em)). 相似文献
