Finite density and temperature in hybrid bag models

We introduce the chemical potential in a system of two-flavored massless fermions in a chiral bag by imposing boundary conditions in the Euclidean time direction. We express the fermionic mean number in terms of a functional trace involving the Green function of the boundary value problem, which is studied analytically. Numerical evaluations for the fermionic number are presented.Comment: 19 pages, 4 figure

Confined two-dimensional fermions at finite density

We introduce the chemical potential in a system of two-dimensional massless fermions, confined to a finite region, by imposing twisted boundary conditions in the Euclidean time direction. We explore in this simple model the application of functional techniques which could be used in more complicated situations.Comment: 15 pages, LaTe

Pc5 geomagnetic field fluctuations at discrete frequencies at a low latitude station

International audienceA statistical analysis of the geomagnetic field fluctuations in the Pc5 frequency range (1?5 mHz) at a low latitude station (L = 1.6) provides further evidence for daytime power peaks at discrete frequencies. The power enhancements, which become more pronounced during high solar wind pressure conditions, may be interpreted in terms of ground signatures of magnetospheric cavity/waveguide compressional modes driven by solar wind pressure pulses. In this sense, the much clearer statistical evidence for afternoon events can be related to corotating structures mainly impinging the postnoon magnetopause. A comparison with results obtained for the same time intervals from previous investigations at higher latitudes and in the Earth's magnetosphere confirms the global character of the observed modes

Geomagnetic field fluctuations during the passage at the Earth's orbit of the tail of the 15?16 July 2000 ejecta

International audienceIn this work we present the analysis of the geomagnetic field fluctuations observed at different ground stations (approximately along two latitudinal arrays, separated by several hours in local time) during the passage at the Earth's orbit of the tail of the 15?16 July 2000 coronal ejecta. The time interval of interest is characterized by northward interplanetary magnetic field conditions and several changes in the solar wind dynamic pressure. We found at all stations, both in the local morning and in the local evening, simultaneous and highly coherent waves at the same discrete frequencies (~ 1.8 and ~ 3.6 mHz) and suggest a possible interpretation in terms of global compressional modes driven by an impulsive variation of the solar wind pressure. Along the array situated in the morning sector, at the highest latitudes, the higher frequency mode seems to couple with the local field line resonance; on the other hand, along the array situated in the evening sector, the characteristics of the observed fluctuations suggest that the highest latitude station could be located at the footprint of open field lines. Our results also show that solar wind pressure variations observed during the recovery phase of the storm do not find correspondence in the geomagnetic field variations, regardless of local time and latitude; conversely, some hours later continuous solar wind pressure variations find a close correspondence in the geomagnetic field variations at all stations

Effects of different fertilizers on quantity and quality of silage corn

Different fertilizers, ammonia sulfate and urea (MIN), Fertil 12.5 (ORG) and Azoslow (ORG-MIN) were compared in a silage corn crop. Total biomass yield was above 55.0 t ha-1 for all fertilizers. Azoslow showed the highest dry matter content (40.8%). No differences among the fertilizers were found in protein content (4.9% on average) at waxy ripening, with the control showing the lowest value (3.9%). There were also no differences in silage quality among the fertilizers. The N budget was estimated in order to quantify the residual nitrogen amounts at harvest and the efficiency of fertilizers

Colgajo libre córtico-perióstico de la arteria genicular descendente en el tratamiento de la seudoartritis distal de tibia

Presentamos un caso de un varón de 35 años con pseudoartrosis aséptica de tibia distal con escaso defecto óseo, intervenido previamente mediante recambio del material de osteosíntesis e injerto de cresta iliaca, que fracasó. Tras estudio de las diferentes opciones de tratamiento, se le propuso estabilizar el foco mediante enclavado endomedular y aumentar la capacidad osteogénica con un colgajo córtico-perióstico de la arteria genicular descendente, según la técnica de Sakai. Discusión: El manejo terapéutico de la pseudoartrosis distal de tibia no está del todo resuelto. Cuando otras opciones no han sido efectivas, el clavo endomedular asociado al colgajo libre córtico-perióstico de la arteria genicular descendente puede ser una opción válida para el tratamiento. Esta técnica quirúrgica supone un trabajo coordinado entre los especialistas en traumatología y cirugía plástica.We present a case of 35 years old man presented with aseptic distal tibial nonunion without bone defect. Previous unsuccessful surgical attempt, consisting on revision of the internal fixation and iliac crest bone grafting, was performed. After studying the different treatment options, we suggested him to carry out an endomedular nail stabilization of the nonunion site in combination with a descending genicular corticoperiosteal free flap to provide osteogenetic enhancement, as described by Sakai. Discussion: The treatment protocol of the distal tibial nonunion still remains controversial. When other surgical attempts are unsuccessful, the combination of endomedular nailing and descending genicular corticoperiosteal free flap, may be useful. This surgical technique may require a coordinated work between orthopaedic and plastic surgeons
