Abstract in Spanish Este trabajo presenta algunas reflexiones preliminares acerca del desarrollo rural en el nordeste de Argentina a la luz de los cambios socio-económicos y políticos acontecidos en los últimos veinte años aproximadamente. Así, por ejemplo, los procesos de descentralización que han tenido lugar en este país durante la década de 1990 ilustran la complejidad de las estrategias de de
Double-stranded DNA bacteriophages are highly stressed under the high internal pressure that is described as stored energy. Most of them eject their genome into the host bacteria via receptor binding. In the previous work, isothermal titration calorimtery (ITC) was used, for first time, to directly measure the heat released during DNA ejection from the phage lambda, triggered in solution by solubi
A statistical analysis of amplitudes corresponding to multipath components in outdoor (urban/suburban) channels is presented. The study is based on short-term complex impulse response measurements conducted in Stockholm at 1.88 GHz carrier frequency with 5 MHz bandwidth. The actual investigations show that the Rice distribution gives the best fitting in the Kramer-von-Mises sense. Further it is sh
Neuronal cell suspensions prepared from the ventral mesencephalon and the septal-diagonal band area of rat embryos were implanted into the depth of the intact neostriatum or hippocampus of 21-23 month old female rats. Graft survival, assessed 3-4 months after grafting, was comparable to that seen in our previous studies of young adult recipients. Fibre outgrowth into the host brain was evaluated i
Medical education seemingly immune to discussions of gender. Study indicates gender perspective in teaching is lacking Maria Norstedt, Karen Davies Läkartidningen 2003:100;2056-62 This article builds upon qualitative interviews with teachers and students in the medical education at Lund university. The results found that a gender perspective is understood primarily in terms of the biological body.
Oxide nanoparticle layers have shown interesting behavior as gate materials for high temperature (typically at 300-400°C) metal-insulator-silicon carbide (MISiC) capacitive sensors. Distinct shifts in the depletion region of the C-V (capacitance-voltage) characteristics could be observed while switching between different oxidizing and reducing gas ambients (air, O2, H2, NH3, CO, NOx, C3H6). Shifts
Hälso- och sjukvården står inför en mängd förändringar och en allt mer komplex och utmanande situation, världen över. Förändringarna sker tvärsektoriellt och på alla plan: Ökad kundfokusering, nya rön om styrning och ledning, forskningsframsteg, ny teknik, ny vårdpraxis, öppna kvalitetsjämförelser, kompetensspecialisering och maktförskjutningar. Förändringarna sker inte bara lokalt utan även regio
We provide a general mechanism for obtaining uniform information from pointwise data even when the pertinent quantities are highly discontinuous. Some of the applications are almost too good to be believed: If a diffeomorphism of a com-pact Riemannian manifold has nonzero Lyapunov exponents everywhere then the nonwandering set is uniformly hyperbolic. If, in addition, there are expanding and contr
