Cans, Roger, 1997: Jacques-Yves Cousteau (1910-97). The renowned inventor, filmmaker, and ocean explorer Jacques-Yves Cousteau (1910-97) died of heart disease at his home in Paris, France, on June 25. Through various technological innovations, such as the aqualung, Cousteau provided oceanography wi...

Dorn, A.; Hoffmann, P., 1981: The 'embryonic moults' of the milkweed bug as seen by the S.E.M. Deposition, detachment and removal of the 3 embryonic cuticles are studied. The membrane-like cuticle 1 covers the embryo during katatrepsis and disappears thereafter. Cuticle 2 deposition starts shortly before dorsal closure. Its apolysis is acco...

Habib, A.G., 2002: Tetanus complicating snakebite in northern Nigeria: clinical presentation and public health implications. There is inequality in vaccination coverage, and adult farmers in tropical rural communities could have missed tetanus toxoid as campaigns target children. Snakebite is not uncommon and partly because of lack of effective antivenom, management in...

Wulfsberg, E.A.; Campbell, A.B.; Lurie, I.W.; Eanet, K.R., 1996: Confirmation of the Catania brachydactylous type of acrofacial dysostosis: report of a second family. The acrofacial dysostoses (AFD) are a heterogeneous group of disorders combining varying severities of mandibulofacial dysostosis (MFD) with pre- and/or postaxial limb abnormalities. In 1993, Opitz et al. (Am J Med Genet 47:660-678) described a ne...

Li, X.; Li, B.; Yang, B.; Zeng, T., 2013: General framework to histogram-shifting-based reversible data hiding. Histogram shifting (HS) is a useful technique of reversible data hiding (RDH). With HS-based RDH, high capacity and low distortion can be achieved efficiently. In this paper, we revisit the HS technique and present a general framework to construct...

Kedia, N.; Roy, S.Ghosh.; De, P.; Bagchi, S., 2014: Synthesis of a polymer bearing several coumarin dyes along the side chain and study of its fluorescence in pure and binary solvent mixtures as well as aqueous surfactant solutions. A copolymer bearing several pendent dyes (coumarin derivatives) along the side chain has been synthesized, and its fluorescence parameters have been monitored in pure solvents and also as a function of composition of binary solvent mixtures. Fluor...

Chu, T.L.; Shih, S.C., 1949: Studies on variations of some important characters in first year seedlings of sugar cane. The material studied consisted of first year seedlings from 14 hybrid combinations. Heritable variation was found between the different combinations in the average number of green leaves. Variation in the average width of the third leaf from the t...

Sidorenko, M.V.; Osinskiĭ, S.P., 1984: Determination of the pH of solid tumors. The design and production technique of pH-electrode for measuring pH in solid tissues are described. Main characteristics of the pH electrode are determined: external diameter 0.25-0.4 mm, length of the pH-sensitive part--4-10 mm, sensitivity at 3...

Connors, B.W., 2002: Single-neuron mnemonics. In this issue, Egorov et al. provide new insight into the process of short-term memory. The researchers studied single neurons in a region of the rat brain called the entorhinal cortex, which is essential for working memory during specific behavio...
