Abstract The purpose of this article is to construct an explicit relation between the field operators in Quantum Field Theory and the relevant operators in Quantum Mechanics for a system of N identical particles, which are the symmetrised functions o

Introduction: Peripheral facial palsy (PFP) is commonly diagnosed in every emergency department. Despite being a benign condition in most cases, PFP causes loss in quality of life mostly due to facial dysmorphia. The etiology of PFP remains unknown i

Nos doentes com cancro da mama, o tratamento neoadjuvante tem um papel fundamental na diminuição do tamanho do tumor, possibilitando uma cirurgia conservadora, sem um aumento significativo da recorrência local. Estudos mais recentes revelaram tamb

Competition with fisheries and incidental capture in fishing gear are the major current threats for seabirds at sea. Fishing is a traditional activity in Portugal and is mainly composed of a great number of small vessels. Given the lack of knowledge

We provide a compact derivation of the Dirac bracket and of the equations of motion for second class constrained systems when the constraints are time dependent. The examples of Parameterized Mechanics and of General Relativity after gauge fixing are

O tamponamento nasal anterior é efetuado num grande número de cirurgias nasais, nomeadamente na septoplastia. Contudo, não é um procedimento inócuo pelo que o seu benefício tem vindo a ser questionado. OBJETIVO: Avaliar a necessidade do tampona

We used data from a magnetometer on board the ISS to simulate the Earth's magnetic field. For that purpose, we generated two models from the data and compared them: an off-centered dipole model and a centered multipolar model. We found out that measu

We construct the algebra of operators acting on the Hilbert spaces of Quantum Mechanics for systems of $N$ identical particles from the field operators acting in the Fock space of Quantum Field Theory by providing the explicit relation between the po
