Primer registro del género Jenynsia Günther, 1866 (Teleostei: Cyprinodontiforme...
Bogan,Sergio; de los Reyes,Martín L.; Cenizo,Marcos M.En este trabajo se da a conocer un premaxilar izquierdo referible al género Jenynsia recuperado en facies lacustres correspondientes al Piso-Edad Bonaerense (Pleistoceno Medio tardío) de la localidad de Centinela del Mar, provincia de Buenos Aires, Argentina. Dicho material constituye el primer registro fósil para este género y uno de los escasos antecedentes para la familia Anablepidae. El hallazgo aquí comuni...
Results from a new combined test of an electromagnetic liquid argon calorimeter...
Akhmadaliev, S.; Albiol, F.; Amaral, P.; Ambrosini, G.; Amorim, A.; Anderson, K.; Andrieux, M. L.; Aubert, B.; Augé, E.; Badaud, F.; Baisin, L.A new combined test of an electromagnetic liquid argon accordion calorimeter and a hadronic scintillating-tile calorimeter was carried out at the CERN SPS. These devices are prototypes of the barrel calorimeter of the future ATLAS experiment at the LHC. The energy resolution of pions in the energy range from 10 to 300 GeV at an incident angle [theta] of about 12° is well described by the expression , where E is...
Phylogenetic systematics of the Eucarida (Crustacea malacostraca)
Christoffersen,Martin L.Ninety-four morphological characters belonging to particular ontogenetic sequences within the Eucarida were used to produce a hierarchy of 128 evolutionary novelties (73 synapomorphies and 55 homoplasies) and to delimit 15 monophyletic taxa. The following combined Recent-fossil sequenced phylogenetic classification is proposed: Superorder Eucarida; Order Euphausiacea; Family Bentheuphausiidae; Family Euphausiid...
