Injured Salvator merianae (Teiidae) regenerates six tails in central Argentina
(Asociación Herpetológica Argentina, 2016-09)
Lizards have the ability of regenerate many tissues like nerve cells, part of the mandible, parts of the limb, and most of them can regenerate the tail. Tail autotomy followed by tail regeneration is a strategy widely used ...
Some vaguely explored (but not trivial) costs of tail autotomy in lizards
Lizard tail autotomy is considered an efficient anti-predator strategy that allows animals to escape from a predator attack. However, since the tail also is involved in many alternative functions, tailless animals must ...
An example of a heavy tailed distribution
Dissolved pollutant transport in tailings ponds
Water and dissolved ion transport in mineral tailings was studied at laboratory scale with three different tailings samples. Percolation rate, determined in column experiments, depends mainly on the granulometric distribution ...
Froth flotation of coal tailings
(ESCOLA DE MINAS, 2009)
The processes involved in coal preparation produce harmful effects for the environment, mainly by the quantity and nature Of wastes that are generated, These tailings generally called ""pyritic"", even though not presenting ...
Considerations on the kinetics of froth flotation of ultrafine coal contained in tailings
(Taylor & Francis Inc, 2009)
This article presents a kinetic evaluation of froth flotation of ultrafine coal contained in the tailings from a Colombian coal preparation plant. The plant utilizes a dense-medium cyclones and spirals circuit. The tailings ...
ELECTRO-REMEDIATION OF COPPER MINE TAILINGS. COMPARING COPPER REMOVAL EFFICIENCIES FOR TWO TAILINGS OF DIFFERENT AGE
(PERGAMON-ELSEVIER SCIENCE LTD,, 2013)
alpha(1)-Adrenoceptors in proximal segments of tail arteries from control and reserpinised rats
It has been recently shown that the supersensitivity of distal segments of the rat tail artery to phenylephrine after chemical sympathectomy with reserpine results from the appearance of alpha(1D)-adrenoceptors. It is known ...
Tail anatomy of Buitreraptor gonzalezorum (Theropoda, Unenlagiidae) and comparisons with other basal paravians
(Academic Press Ltd - Elsevier Science Ltd, 2017-09)
Tail anatomy of unenlagiid theropods remains poorly known. The most complete and informative taxon of this family is Buitreraptor gonzalezorum from the Upper Cretaceous of Rio Negro province, Argentina. The aim of the ...
