Swimming performance of the migratory Neotropical fish Leporinus reinhardti (Characiformes: Anostomidae)

Neotropical Ichthyology
The fishways built in Latin America were mainly based on those used in the northern hemisphere for passing salmonids upstream. However, the swimming capacity in terms of speed and endurance is a major factor concerning the design of a fishway, and this ...

Overview of the lithium problem in metal-poor stars and new results on 6Li

, 2008
Two problems are discussed here. The first one is the 0.4 dex discrepancy between the 7Li abundance derived from the spectra of metal-poor halo stars on the one hand, and from Big Bang nucleosynthesis, based on the cosmological parameters constrained by ...

The cosmic lithium problem: an observer's perspective

, 2012
Using the cosmological constants derived from WMAP, the standard big bang nucleosynthesis (SBBN) predicts the light elements primordial abundances for 4He, 3He, D, 6Li and 7Li. These predictions are in satisfactory agreement with the observations, except

Enhancing Diabetic Foot Ulcer Classification Through Fine-Tuned Multilevel CNN

IEEE Access
Diabetic foot ulcers (DFUs) are especially problematic with their high rates of recurrence. Recognizing DFUs with infection and ischemia is vital for appropriate treatment and prevention of amputations.

Circadian changes in thyroid hormones of piau, Leporinus obtusidens Valenciennes, 1847 (Osteichthyes, Anostomidae) after feeding = Variações circadianas dos hormônios tireoidianos de piau, Leporinus obtusidens Valenciennes, 1847 (Osteichthyes, Anostomidae) após alimentação

Acta Scientiarum: Biological Sciences, 2009
To evaluate circadian changes in thyroid hormones of piau, Leporinusobtusidens Valenciennes, 1847, (Osteichthyes, Anostomidae) after feeding were determined the plasma levels of thyroid hormones (TH) of 128 fishes, same age, immature, both sexes, distributed into four classes of weight. They were kept in 16 aquaria (100 L), with artificial aeration and
