Holonomy Transformation in the FRW Metric
In this work we investigate loop variables in Friedman-Robertson-Walker
spacetime. We analyze the parallel transport of vectors and spinors in several
paths in this spacetime in order to classify its global properties. The band
holonomy invariance is analysed in this background.Comment: 8 page

Detection of Exotic Massive Hadrons in Ultra High Energy Cosmic Ray Telescopes
We investigate the detection of exotic massive strongly interacting hadrons
(uhecrons) in ultra high energy cosmic ray telescopes. The conclusion is that
experiments such as the Pierre Auger Observatory have the potential to detect
these particles. It is shown that uhecron showers have clear distinctive
features when compared to proton and nuclear showers. The simulation of uhecron
air showers, and its detection and reconstruction by fluorescence telescopes is
described. We determine basic cuts in observables that will separate uhecrons
from the cosmic ray bulk, assuming this is composed by protons. If these are
composed by heavier nucleus the separation will be much improved. We also
discuss photon induced showers. The complementarity between uhecron detection
in accelerator experiments is discussed.Comment: 9 page 9 figure
Volatilização de amônia de adubos nitrogenados aplicados no feijoeiro irrigado cultivado no sistema plantio direto.
Este trabalho teve como objetivo avaliar as perdas de N por volatilização de NH3, com a aplicação de diferentes fontes nitrogenadas no feijoeiro cultivado em sistema plantio direto no inverno
Psoriasis treatment with biologics: beyond tumor necrosis factor α inihibitors – The present and the future
A psorÃase é uma doença inflamatória crónica multissistémica, mediada por células T, com elevado grau de morbilidade. A investigação na área da psorÃase tem sido intensa, resultando num conhecimento mais porme- norizado da sua patogenia, e consequente desenvolvimento de novas terapêuticas biológicas. Esta revisão focará o presente e o futuro dos agentes biológicos moduladores de citoquinas que não pertencem à classe dos inibidores do factor de necrose tumoral-α (TNF-α)
