q-Deformed Brownian Motion

Brownian motion may be embedded in the Fock space of bosonic free field in one dimension.Extending this correspondence to a family of creation and annihilation operators satisfying a q-deformed algebra, the notion of q-deformation is carried from the algebra to the domain of stochastic processes.The properties of q-deformed Brownian motion, in particular its non-Gaussian nature and cumulant structure,are established.Comment: 6 page

A New Approach to Canonical Quantization of the Radiation Damping

Inspired in some works about quantization of dissipative systems, in particular of the damped harmonic oscillator\cite{MB,RB,12}, we consider the dissipative system of a charge interacting with its own radiation, which originates the radiation damping (RD). Using the indirect Lagrangian representation we obtained a Lagrangian formalism with a Chern-Simons-like term. A Hamiltonian analysis is also done, what leads to the quantization of the system.Comment: 5 page

Supersymmetrization of the Radiation Damping

We construct a supersymmetrized version of the model to the radiation damping \cite{03} introduced by the present authors \cite{ACWF}. We dicuss its symmetries and the corresponding conserved Noether charges. It is shown this supersymmetric version provides a supersymmetric generalization of the Galilei algebra obtained in \cite{ACWF}. We have shown that the supersymmetric action can be splited into dynamically independent external and internal sectors.Comment: 9 page

The impact of home care nursing in puerpera dificulties

BACKGROUND: The birth of the first child forwards the new mother to an individual, family and social reset in order to deal with self-caring and parenting skills. Many women in postpartum period report having to deal often with new doubts and/or problems. OBJECTIVE: Identify the main difficulties reported by mothers during puerperium time. Compare those mentioned difficulties, between control group and study group. METHODS: Quasi-experimental design - Control group and study group with 200 primiparous women (100 women in each group). Participants in the study group were submited to at least two home visits during the postpartum period. RESULTS: Chi-square test revealed statistically significant differences between groups, for participants who did not report difficulties (p=0.021). A larger number of mothers in the experimental group did not mention difficulties (38%), compared to those belonging to the control group (23%). The three main difficulties were found: Understanding child's cry - 53% in the control group and 45% in study group; Child feeding - 29% in the control group and 21% in study group; “Psychological changes” are referred by both groups in thirdly. Chi-square test shows differences between groups in this variable (p=0.037) - Control group 27% and study group 15%. CONCLUSIONS: This investigation demonstrated the relationship between home visit and expressed difficulties: a higher number of participants followed during puerperium did not mention difficulties. For those who mentioned difficulties also the groups show different regarding the difficulty in dealing with the psychological changes. More mothers from control group mentioned this problem
