The abyssal circulation in the interior portions of Brazil Basin and northern Argentine were estimated using an overdetermined inverse method conserving neutral surface planetary potential vorticity salinity. Antarctic Bottom Water (AABW) flows with a northward component through 30°S west Rio Grande Rise (RGR), as expected. However, area east RGR, model shows southward transport upper part AABW...

All known visual pigments in Neuralia (Cnidaria, Ctenophora, and Bilateria) are composed of an opsin (a seven-transmembrane G protein-coupled receptor), and a light-sensitive chromophore, generally retinal. Accordingly, opsins play a key role in vision. There is no agreement on the relationships of the neuralian opsin subfamilies, and clarifying their phylogeny is key to elucidating the origin ...

We propose an improved restart strategy for randomized backtrack search and compare its performance to other search mechanisms in the context of solving a tight real-world resource allocation problem. The restart strategy proposed by Gomes et al. [1] requires the specification of a cutoff value determined from an overall profile of the cost of search for solving the problem. When no such profil...

Relations for possible local quasars are studied: the “mass-radius”, “density-mass”, and “radius-density” relations. These relations show clear fragmentation and which is due to the presence of parallel sequences of observations. The cause for this unusual fragmentation is the presence of a term depending on rgr/rq in each respective relation. It seems therefore that fragmentation in these rela...

Seasonal drought is a common phenomenon in many forests predominated by monsoon climate. The impact of seasonal drought, however, may vary with elevations, and tree species of forests hence may differ in their response to elevations. In this study, we monitored the seasonal variation of seedling species composition, and their relative growth rate (RGR) along an elevational transect in tropical ...

Budidaya vaname dilakukan dengan harapan dapat memacu pertumbuhannya secara maksimum, sehingga menyesesuaikan permintaan selalu meningkat. Pemberian pakan protein tinggi dan sesuai kebutuhannya diharapkan mampu meningkatkan laju pertumbuhan juvenile vaname.Tujuan dari penelitian ini adalah untuk men...

The Rio Grande Rise (RGR) is an extensive structural high located in the South Atlantic Ocean, target of increasing exploratory interest. During last decades, considerable attention has been given to its genesis, dynamic, regional tectonic, and composition. Some studies indicate presence volcanic rocks, mainly basaltic, related their origin Ferromanganese Crusts, boosting research economic This...

Relative growth rates (RGR) have both intrigued and irritated many plant scientists since they were proposed as characteristics of performance in the early 20th century. Particularly, common trend RGR to decrease with increasing size, also referred ontogenetic drift, has given rise debates much criticism. In this study, we showed that, plants that germinated at same time, it is obtain a linear ...

Given that the characteristic of free floating plants to uptake metals can have a positive effect on the efficiency of the remediation process of a wetland, it is important to investigate the factors that may impact the process of uptake of metals by the plants. By conducting this present study over a short duration of time, the effects of salinity on the growth, the content of the photosynthet...
