We formulate the on-shell effective field theory (OSEFT) in an arbitrary frame and study its reparametrization invariance (RI), which ensures that it is respectful of Lorentz symmetry. In this ...formulation the OSEFT Lagrangian looks formally equivalent to the sum over light-like velocities of soft collinear effective field theory in the Abelian limit, differences remain in the scale of the gauge fields involved in the two effective theories. We then use the OSEFT Lagrangian expanded in powers of the on-shell energy to derive how the classical transport equations for charged massless fermions are corrected by quantum effects, as derived from quantum field theory. We provide a formulation in a full covariant way, and explain how the consistent form of the chiral anomaly equation can be recovered from our results. We also show how the side jump transformation of the distribution function associated with massless charged fermions can be derived from the RI transformation rules of the OSEFT quantum fields. Finally, we discuss differences in our results with others found in the literature.
The synthesis of ten symmetrically and unsymmetrically substituted 1,3,5-triazines by Phase Transfer Catalysis (PTC) method is described. Their toxicities were determined against Artemia salina ...Leach. The LD50 values have also been obtained for these compounds.
Bone Marrow Transplantation (BMT) has emerged over the past decade as a new and promising intervention for the Haemato-Oncologic patients or those who have a sensitive tumour to intensive ...chemotherapy. The application of high-dose of intensive chemotherapy reduces the relapse risk of the illness, increases survival and the possibility of total recovery on the vast majority of cases. However, the patients undergoing this treatment may experience several and multiple potential stressors on long, medium and short term basis. The quality care requires a personal, multidimensional, integral and interdisciplinary approach of these patients and their relatives during the different stages of the treatment. A proposal of a psycho-educational program is presented in order to help patients face the BMT, starting the transplant on the best conditions as possible and facilitating their adaptation during the whole process. This intervention is being realized in the Haematology and Hemotherapy Service on the University Hospital La Paz, Madrid, where 450 patients and their relatives have already participated
The number of aggressions towards health care professionals has risen over the past few years. There are no previous studies in primary care covering an entire region and to all professional ...categories. The aim of this study was to characterize aggressions in Primary Care in the Community of Madrid.
Multicenter cross-sectional study. Analysis of a Registration System that reports any type of aggression suffered by Primary Care workers, in the Community of Madrid. The study variables included sociodemographic characteristics of the aggressor and the victim, the type of aggression (verbal or physical abuse), its causes and consequences. We described median, intercuartilic range and frequencies. Logistic regression was performed calculating odds ratio and their 95% confidence intervals.
1,157 assaults were reported, 53.07% suffered by doctors. Physical assault occurred in 4.7% of the cases. The main reason was dissatisfaction with the care (36.1%). The non-medical staff showed less risk of being physically assaulted (OR: 0.38; CI95%: 0.17-0.86). The perpetrator profile was male (56.8%), aged between 31-40 (26.8%) years. Health care victim profile was female (84%), aged between 45-60 years. 10% of professionals reported some form of aggression, 5,9% of aggression were submitted to court.
The risk of assault is higher in health personnel, particularly physicians. There were significant differences by gender and age, both in the profile of the aggressor and the victim.
We study the dynamical evolution of the so-called chiral magnetic effect in an electromagnetic conductor. To this end, we consider the coupled set of corresponding Maxwell and chiral anomaly ...equations, and we prove that these can be derived from chiral kinetic theory. After integrating the chiral anomaly equation over space in a closed volume, it leads to a quantum conservation law of the total helicity of the system. A change in the magnetic helicity density comes together with a modification of the chiral fermion density. We study in Fourier space the coupled set of anomalous equations and we obtain the dynamical evolution of the magnetic fields, magnetic helicity density, and chiral fermion imbalance. Depending on the initial conditions we observe how the helicity might be transferred from the fermions to the magnetic fields, or vice versa, and find that the rate of this transfer also depends on the scale of wavelengths of the gauge fields in consideration. We then focus our attention on the quark-gluon plasma phase, and analyze the dynamical evolution of the chiral magnetic effect in a very simple toy model. We conclude that an existing chiral fermion imbalance in peripheral heavy ion collisions would affect the magnetic field dynamics, and consequently, the charge dependent correlations measured in these experiments.
