Description and chemical composition of manganese nodules collected during Hakuho Maru Cruise KH-72-2, Oct-Dec, 1972 in the Southwest Japan Arc and Ryukyu Arc areas

The cores and dredges described in this report were taken on the KH-72-2 Expedition in October-December, 1972 by the Ocean Research Institute, University of Tokyo from the R/V Hakuho Maru. A total of 21 cores and dredge sites have been recovered.

A new OCT finding in tuberculous serpiginous-like choroidopathy.

PURPOSE To present a case of tubercular serpiginous-like choroiditis (SLC) with previously unreported choroidal findings on enhanced depth imaging OCT (EDI-OCT). DESIGN Case report. METHODS A 60-year-old female presented with decreased vision. Serpiginous choroidopathy was diagnosed. Laboratory workup revealed an infectious etiology. EDI-OCT revealed previously unreported choroidal findings. RESULTS Laboratory workup revealed nonreactive Treponema pallidum antibodies and positive QuantiFERON Gold. CT chest showed scars of prior granulomatous disease. OCT with EDI of active lesions demonstrated infiltration of the choroid, elevation of the RPE-Bruch's membrane complex and focal increase of choroidal thickness. CONCLUSIONS Choroidal infiltration with elevation of the RPE was demonstrated on EDI-OCT in active areas of tuberculous serpiginous-like choroiditis in this patient. This finding has not been described in imaging of patients with noninfectious serpiginous choroidopathy and may be a useful tool to differentiate serpiginous choroidopathy (SC) from serpiginous-like choroiditis (SLC). EDI-OCT may provide characterization of choroidal involvement.

Discussion of "Bibliography and Data on Cable-Stayed Bridges", by the Subcommittee on Cable-Stayed Bridges of the Committee on Long-Span Steel Bridges of the Committee on Metals of the Structural Division (Oct., 1977)

The writer would like to point out the existence of a very remarkable Spanish cable-stayed bridge built in 1925, wich is thus older than the first one recorded by the authors (and probably the pioneer in concrete-deck type). The Tempul Aqueduct was designed by the famous Professor Educardo Torroja. The deck is a concrete box girder sustained by two planes of 3 mm diam 37-wire double cables working at 27 kg/mm2.

Desarrollo de un sistema para la conversión de imágenes de vídeo PAL a imágenes HD

En las ultimas décadas hemos sufrido un gran cambio en el modo, como en la calidad de Vida en el cual se debe a gran medida al avance tan grande que ha habido en el mundo tecnológico. Alguno de estos avances y en el cual tratara el proyecto son la codificaciones y formato de video. En las décadas que llevamos de televisión en color hay dos formatos de video en los cuales han destacado sobre el resto uno que es el sistema de codificación analógico PAL ,que es el sistema de televisión Analógica que se utilizaba en toda Europa (Exceptuando Francia) y en la mayoría de la población mundial. Por otro lado tenemos el otro sistema de video que es el HD aunque el proyecto lleva 40 años existiendo he tomado una mayor importancia ahora con el cambio que se ha habido de pasar de una televisión analógica a una televisión digital. En este proyecto se creara una herramienta capaz de transformar un video en Formato PAL que es un formato que tiene 720 pixeles de longitud y 576 pixeles de altura al formato de video HD que en su caso tiene las dimensiones 1920x 1080 pixeles de longitud y altura respectivamente.

Arabidopsis DELLA and two HD-ZIP transcription factors regulate GA signalling in the epidermis through the L1 cis-element

Gibberellins (GAs) are plant hormones that affect plant growth and regulate gene expression differentially across tissues. To study the molecular mechanisms underlying GA signaling in Arabidopsis thaliana, we focused on a GDSL lipase gene (LIP1) induced by GA and repressed by DELLA proteins. LIP1 contains an L1 box promoter sequence, conserved in the promoters of epidermis-specific genes, that is bound by ATML1, an HD-ZIP transcription factor required for epidermis specification. In this study, we demonstrate that LIP1 is specifically expressed in the epidermis and that its L1 box sequence mediates GA-induced transcription. We show that this sequence is overrepresented in the upstream regulatory regions of GA-induced and DELLA-repressed transcriptomes and that blocking GA signaling in the epidermis represses the expression of L1 box–containing genes and negatively affects seed germination. We show that DELLA proteins interact directly with ATML1 and its paralogue PDF2 and that silencing of both HD-ZIP transcription factors inhibits epidermal gene expression and delays germination. Our results indicate that, upon seed imbibition, increased GA levels reduce DELLA protein abundance and release ATML1/PDF2 to activate L1 box gene expression, thus enhancing germination potential.
