Abstract An assemblage of 50 species small shelly fossils is described from Cambrian Series 2 (Stage 4) strata in North Greenland, the present day northernmost part paleocontinent Laurentia. The are derived basal member Aftenstjernesø Formation at Navarana Fjord, northern Lauge Koch Land, a condensed unit that accumulated sediment-starved outer ramp setting transarctic Franklinian Basin, on Inn...

Oreochromis niloticus is one of the most widespread species in Africa. Its introduction around world economic and social benefit especially rural communities where they are caught from wild or cultured captivity. Length frequency distribution was used to estimate age this commercial fish between May October, 2012. A year old (1+) specimen had a total length size class 100-121 mm. Other classes ...

Lateglacial climatic oscillations exerted profound impacts on the Meuse fluvial system. In Lower (southern Netherlands), geomorphological studies in last decades mainly centred vegetation evolution, channel pattern changes and river terrace formation. Little information has been reported about paleohydrology its relation with regional climate conditions. This study investigates a sediment core ...

Upon his death in 1955, Albert Einstein's brain was removed, fixed and photographed from multiple angles. It was then sectioned into 240 blocks, and histological slides were prepared. At the time, a roadmap was drawn that illustrates the location within the brain of each block and its associated slides. Here we describe the external gross neuroanatomy of Einstein's entire cerebral cortex from 1...

The present study has investigated interaction at the cortical level in the human between two major components of flavor perception, pure chemical gustatory and lingual somatosensory perception. Twelve subjects participated in a functional magnetic resonance imaging study and tasted six stimuli, applied on the whole tongue, among which four were pure gustatory stimuli (NaCl, aspartame, quinine ...

We found that vitamin C is an essential nutrient for an Amazonian ornamental fish, the oscar (Astronotus ocellatus). This was demonstrated by the absence of L-gulonolactone oxidase activity, the enzyme responsible for the biosynthesis of vitamin C, in liver or kidney of oscars and by a feeding trial in which oscars without vitamin C dietary supplementation developed clinical deficiency signs. F...

Deficiency in dietary phosphorus (P) is considered as a nutritional risk factor for the development of vertebral column deformities farmed Atlantic salmon Salmo salar, L. This mono-factorial study examines how 11-week deficiency and excess P influence structure microstructure bodies juvenile, freshwater stages salmon. Animals were fed continuously with three diets containing different levels to...
