The Presence of Flavonoids in Some Products and Fruits of the Genus Eugenia: An Integrative Review
ReviewThe Myrtaceae family, one of the most prominent botanical families, is represented in Brazil
with different fruit species, rich in bioactive compounds and gastronomically appreciated.
This study aimed to carry out an integrative review on the genus Eugenia, highlighting the
pitangueira (E. uniflora L.), cagaiteira (E. dysenterica), grumixameira (E. brasiliensis), pereira
(E. klotzschiana O. Berg), and uvaieira (E. pyriformis Cambess) and which flavonoids are
present in these fruits. Articles published between 2016 and 2021 were selected from the
following databases: Google Scholar, Periódicos CAPES, Scielo, and Science Direct.
According to each database, the descriptors used as a search strategy addressed the
popular and scientific names of the five selected species, associated or not with the term
“flavonoid,” according to each database. The results showed that quercetin was the main
flavonoid identified in the fruits, and the principal extraction method used was HPLC. Other
interesting compounds, such as catechin, epicatechin, rutin, myricetin, and kaempferol,
were also found. However, the amount and type of flavonoids detected varied according to
the applied methodology. Hence, these studies highlight the importance of species of the
genus Eugenia, which promotes beneficial health effects and possible applicability to the
food and pharmaceutical industryinfo:eu-repo/semantics/publishedVersio
Breakup reaction models for two- and three-cluster projectiles
Breakup reactions are one of the main tools for the study of exotic nuclei,
and in particular of their continuum. In order to get valuable information from
measurements, a precise reaction model coupled to a fair description of the
projectile is needed. We assume that the projectile initially possesses a
cluster structure, which is revealed by the dissociation process. This
structure is described by a few-body Hamiltonian involving effective forces
between the clusters. Within this assumption, we review various reaction
models. In semiclassical models, the projectile-target relative motion is
described by a classical trajectory and the reaction properties are deduced by
solving a time-dependent Schroedinger equation. We then describe the principle
and variants of the eikonal approximation: the dynamical eikonal approximation,
the standard eikonal approximation, and a corrected version avoiding Coulomb
divergence. Finally, we present the continuum-discretized coupled-channel
method (CDCC), in which the Schroedinger equation is solved with the projectile
continuum approximated by square-integrable states. These models are first
illustrated by applications to two-cluster projectiles for studies of nuclei
far from stability and of reactions useful in astrophysics. Recent extensions
to three-cluster projectiles, like two-neutron halo nuclei, are then presented
and discussed. We end this review with some views of the future in
breakup-reaction theory.Comment: Will constitute a chapter of "Clusters in Nuclei - Vol.2." to be

Volume I. Introduction to DUNE
The preponderance of matter over antimatter in the early universe, the dynamics of the supernovae that produced the heavy elements necessary for life, and whether protons eventually decay—these mysteries at the forefront of particle physics and astrophysics are key to understanding the early evolution of our universe, its current state, and its eventual fate. The Deep Underground Neutrino Experiment (DUNE) is an international world-class experiment dedicated to addressing these questions as it searches for leptonic charge-parity symmetry violation, stands ready to capture supernova neutrino bursts, and seeks to observe nucleon decay as a signature of a grand unified theory underlying the standard model. The DUNE far detector technical design report (TDR) describes the DUNE physics program and the technical designs of the single- and dual-phase DUNE liquid argon TPC far detector modules. This TDR is intended to justify the technical choices for the far detector that flow down from the high-level physics goals through requirements at all levels of the Project. Volume I contains an executive summary that introduces the DUNE science program, the far detector and the strategy for its modular designs, and the organization and management of the Project. The remainder of Volume I provides more detail on the science program that drives the choice of detector technologies and on the technologies themselves. It also introduces the designs for the DUNE near detector and the DUNE computing model, for which DUNE is planning design reports. Volume II of this TDR describes DUNE\u27s physics program in detail. Volume III describes the technical coordination required for the far detector design, construction, installation, and integration, and its organizational structure. Volume IV describes the single-phase far detector technology. A planned Volume V will describe the dual-phase technology
