Dirac and Majorana heavy neutrinos at LEP II
The possibility of detecting single heavy Dirac and Majorana neutrinos at LEP
II is investigated for heavy neutrino masses in the range . We study the process as a clear signature for heavy neutrinos. Numerical estimates for
cross sections and distributions for the signal and the background are
calculated and a Monte Carlo reconstruction of final state particles after
hadronization is presented.Comment: 4 pages, 8 figure
The COVID-19 pandemic: yet another catalyst for governmental mass surveillance?
This commentary addresses the use of surveillance technologies in the context of the Covid-19 pandemic, using examples from the current geopolitical frame, and questioning the possible consequences of data collection for the individual and for society. In this regard, some questions emerge: in the fight against the pandemic, what measures and tools of surveillance are being adopted by the different states? Will the extraordinary measures, that are now being implemented, become permanent? And if so, what will the consequences be for privacy and democracy?info:eu-repo/semantics/publishedVersio
Physical activity level in Physical Therapy students
Physical activity is defined as any body movement that requests energy expenditure. The practice of physical activity allows to reinforce and increase the capacity of muscular-skeletal response and an improvement of physical aptitude. Currently, has been verified that university students have been decreasing healthy lifestyles and increasing their degree of sedentary lifestyle. Thus, it’s essential the Higher Education Institutions present themselves as a way to promote the practice of physical activity and contemplating it in the basic formation.info:eu-repo/semantics/publishedVersio
Level of physical activity and body image in Portuguese and French students, 1st year of Physiotherapy
Adolescents have a physiological need to move, therefore physical activity should be encouraged at an early age. In young adults, there are also various physical and psychological transformations. Associated with these transformations, there is a will to fit in the patterns of society’s beauty and, sometimes, a consequent bodily dissatisfaction. Thus, it is necessary to encourage physical activity, for its benefits.info:eu-repo/semantics/publishedVersio
