The first occurrence of Nototodarus (Cephalopoda: Ommastrephidae) from off Chile, Southeast Pacific (Preliminary Report)

During an exploratory fishing on the so-called 167 Seamount located east of Isla San Felix and Isla San Ambrosia, Chile, eight specimens of "unusual" squids were fished in 1983. Six specimens among them were subjected to a routine biological inspection ein board the research ship, but two were brought home for identification. The results of close examination revealed that this squid belongs to the genus Nototodarus Pfeifer, 1912, which has 11ever been known from the East Pacific. The observations on these two specimens are worth reporting. After a search for literatures and comparisons with Nototodarus specimens in hand, we inclined to consider that these specimens are referrable to N. hawaiiensis (Berry, 1913) by the reason discussed in this report

Cloud optical thickness and effective particle radius derived from transmitted solar radiation measurements : Comparison with cloud radar observations

A method is presented for determining the optical thickness and effective particle radius of stratiform clouds containing liquid water drops in the absence of drizzle from transmitted solar radiation measurements. The procedure compares measurements of the cloud transmittance from the ground at water-absorbing and nonabsorbing wavelengths with lookup tables of the transmittance precomputed for plane-parallel, vertically homogeneous clouds. The optical thickness derived from the cloud transmittance may be used to retrieve vertical profiles of cloud microphysics in combination with the radar reflectivity factor. To do this, we also present an algorithm for solving the radar equation with a constraint of the optical thickness at the visible wavelength. Observations of clouds were made in August and September 2003 at Koganei, Tokyo, Japan, using a PREDE i-skyradiometer and a 95-GHz cloud radar Super Polarimetric Ice Crystal Detection and Explication Radar (SPIDER). The optical thickness and effective radius of water clouds were derived from the i-skyradiometer. Then, the vertical profile of the effective radius was retrieved from SPIDER, using the optical thickness determined from the i-skyradiometer. We found that the effective radii derived by using these two instruments were in good agreement

Practical study on a new type Buckling-Restrained-Brace

p. 303-311A number of a new type Buckling-Restrained-Brace (T-BRB) using steel mortar planks have been applied to various structures (spatial structures, steel bridges and steel towers) as well as multi-story buildings. The brace has two buckling restraining parts (steel mortar planks), clipping a core plate being under axial forces. These parts are welded together and restrain the core plate of plastic behavior, avoiding the out-of-plane deformation and the buckling. The size of steel mortar plank can be designed corresponding to energy absorption demands, irrespectively the sizes of both end-connections. This paper introduces the applications of a new type BRB to various structures.Oya, T.; Fukasawa, T.; Fujiwara, M.; Kuroiwa, Y.; Arai, J. (2009).
