Mineralogical Composition of Clinker as an Indicator of Sulfate Resistance: A Rietveld XRD/Takashima Approach
No full text30 pags., 8 figs., 4 tabs.This study aims to optimize quantitative X-ray diffraction (XRD) mineralogical analysis of the minority phases in clinker. The proposed method consists of applying Rietveld quantitative refinement to the XRD patterns for both clinker and the insoluble residue remaining after it is attacked with methanol and salicylic acid (Takashima method). The method was tested with industrial clinker and the same material after modifying its mineralogy by refiring at 1500°C followed by slow cooling. The findings showed that the C4AF/C3A ratios for quickly and gradually cooled clinker were much higher when the clinker diffractograms were refined with the Rietveld procedure than when the proposed method was used. The proportion of C 3A found with the proposed method was ≈2.8-fold higher than when Rietveld only was applied to the diffractograms for clinkers. Taken together, the refinement data for the two materials (clinker and Takashima residua) revealed that Rietveld quantitative XRD applied to clinker underestimates the low C3A content. These findings are supported by postsulfate attack durability studies conducted on cements prepared with the two clinkers.Supported by the Spanish Ministry of Education and Science (CONSOLIDER

Total length 100–130 mm long. Color of adults uniformly reddish black to greenish black. Pectinal teeth number 12–15 in both sexes. Male with slightly narrower chela than female; chela length/ width ratio 1.79–1.94 in males, 1.69 in female. Chela hirsute, lobiform, without carinae on dorsoexternal surface, but may bear rows of granules. Chela length/ width ratio 1.8–2.0 in adults. Entire manus covered by rounded granules that may merge and appear as rows. Pedipalp patella without pronounced internal tubercle. Carapace smooth, glossy medially, with granules at margins. Second metasomal segment approximately as long as wide. Fifth segment of metasoma about as long pedipalp femur, fourth segment of metasoma shorter than pedipalp femur. Dorsal and dorsolateral carinae of metasomal segments granulated. Vesicle of telson usually longer than aculeus. Spination formula of tarsomeres II of legs: 3-4/4-6: 4/4-5: 4/5-6: 4/5-7. COMMENTS. Palamnaeus serratus Pocock, 1900 was synonymized with H. indus by Couzijn (1981: 121). The first author (Kovařík, 2004: 17 and Kovařík, 2009: 38) accepted the synonymy, whereas Tikader & Bastawade (1983: 555) considered H. serratus a valid species. Examination of additional specimens collected during the Sri Lankan expedition of 2015 convinced us that H. serratus is in fact a valid species. Pocock (1900: 86) differentiated H. serratus and H. indus as follows: 1) dorsal and dorsolateral carinae of metasomal segments granulated in H. serratus (Fig. 574), smooth in H. indus (Fig. 573). We found other minor differences: 2) sexual dimorphism in proportions of pedipalps not noticeable in H. indus, male with slightly narrower chela than female in H. serratus (chela length to width ratio 1.79–1.94 in males, 1.69 in the females); 3) carapace smooth and glossy, only occasionally with granules at margins in H. indus (Figs. 486–487); carapace smooth and glossy medially, always with more granules at margins in H. serratus (Figs. 516–517); 4) spination formula of tarsomeres II of legs: 3/4: 2-4/3-4: 4/4-5: 4/ 5 in H. indus; 3-4/4-6: 4/4-5: 4/5-6: 4/ 5-7 in H. serratus. The distribution of H. serratus was previously unknown, as the type locality was imprecise and the holotype male was the only known specimen. We collected additional specimens at localities cited here as 15CP (Fig. 594) and 15CQ (Fig. 595). Our data suggest that H. serratus is distributed in the southern part, and H. indus in the central part of Sri Lanka (Fig. 15). DISTRIBUTION.

The origin of the lost fleet of the mongol empire
No full textIn 1281 C.E., under the rule of Kublai Khan, the Mongols sent a fleet of more than 4000
vessels to subjugate the island nation of Japan. A powerful typhoon, called kamikaze, dashed the
invading fleet into pieces on the shores of Japan and thus saved the nation from foreign rule.
Historical sources suggest there were three principal vessel types involved in this event:
V-shaped cargo ships for transporting provisions to the front, constructed in China���s Fukien
Province; miscellaneous flat and round bottomed vessels made along the Yangtze River; and flat
bottomed landing craft from Korea.
In the recent past, the remains of the fleet were discovered at the Takashima underwater
site in western Japan, unveiling numerous artifacts including weaponry, shipboard items, and
sections of hull; however, between 1281 and the late twentieth century the site has seen major
disturbances, and the artifacts are often in poor condition. Because the site contains the remains
of ships built in China and Korea, the interpretation of the artifacts is also extremely complex. In
order to determine the origin of the vessels, a logical framework is necessary. The author has
created a timber category database, analyzed methods of joinery, and studied contemporary
approaches to shipbuilding to ascertain the origins and types of vessels that composed the
Mongol fleet. Although no conclusive statements can be made regarding the origins of the vessels, it
appears that historical documents and archaeological evidence correspond well to each other,
and that many of the remains analyzed were from smaller vessels built along the Yangtze River
Valley. Large, V-shaped cargo ships and the Korean vessels probably represent a small portion
of the timbers raised at the Takashima site. As the first research project of its kind in the region,
this study is a starting point for understanding the real story of the Mongol invasion of Japan, as
well as the history of shipbuilding in East Asia

Contrast-enhanced CMR in patients after percutaneous closure of the left atrial appendage: A pilot study
No full textAbstract Background To evaluate the feasibility and value of first-pass contrast-enhanced dynamic and post-contrast 3D CMR in patients after transcatheter occlusion of left atrial appendage (LAA) to identify incorrect placement and persistent leaks. Methods 7 patients with different occluder systems (n = 4 PLAATO; n = 2 Watchman; n = 1 ACP) underwent 2 contrast-enhanced (Gd-DOTA) CMR sequences (2D TrueFISP first-pass perfusion and 3D-TurboFLASH) to assess localization, artifact size and potential leaks of the devices. Perfusion CMR was analyzed visually and semi-quantitatively to identify potential leaks. Results All occluders were positioned within the LAA. The ACP occluder presented the most extensive artifact size. Visual assessment revealed a residual perfusion of the LAA apex in 4 cases using first-pass perfusion and 3D-TurboFLASH indicating a suboptimal LAA occlusion. By assessing signal-to-time-curves the cases with a visually detected leak showed a 9-fold higher signal-peak in the LAA apex (567 ± 120% increase from baseline signal) than those without a leak (61 ± 22%; p Conclusion This CMR pilot study provides valuable non-invasive information in patients after transcatheter occlusion of the LAA to identify correct placement and potential leaks. We recommend incorporating CMR in future clinical studies to evaluate new device types.</p
