Measurement of the Bottom contribution to non-photonic electron production in p+pp+p collisions at s\sqrt{s} =200 GeV

The contribution of $B$ meson decays to non-photonic electrons, which are mainly produced by the semi-leptonic decays of heavy flavor mesons, in $p+p$ collisions at $\sqrt{s} =$ 200 GeV has been measured using azimuthal correlations between non-photonic electrons and hadrons. The extracted $B$ decay contribution is approximately 50% at a transverse momentum of $p_{T} \geq 5$ GeV/$c$. These measurements constrain the nuclear modification factor for electrons from $B$ and $D$ meson decays. The result indicates that $B$ meson production in heavy ion collisions is also suppressed at high $p_{T}$.Comment: 6 pages, 4 figures, accepted by PR

Longitudinal double-spin asymmetry and cross section for inclusive neutral pion production at midrapidity in polarized proton collisions at sqrt(s) = 200 GeV

We report a measurement of the longitudinal double-spin asymmetry A_LL and the differential cross section for inclusive Pi0 production at midrapidity in polarized proton collisions at sqrt(s) = 200 GeV. The cross section was measured over a transverse momentum range of 1 < p_T < 17 GeV/c and found to be in good agreement with a next-to-leading order perturbative QCD calculation. The longitudinal double-spin asymmetry was measured in the range of 3.7 < p_T < 11 GeV/c and excludes a maximal positive gluon polarization in the proton. The mean transverse momentum fraction of Pi0's in their parent jets was found to be around 0.7 for electromagnetically triggered events.Comment: 6 pages, 3 figures, submitted to Phys. Rev. D (RC

Characterization of the volatile fraction emitted by phloems of four pinus species by solid-phase microextraction and gas chromatography–mass spectrometry

Pine forests constitute some of the most important renewable resources supplying timber, paper and chemical industries, among other functions. Characterization of the volatiles emitted by different Pinus species has proven to be an important tool to decode the process of host tree selection by herbivore insects, some of which cause serious economic damage to pines. Variations in the relative composition of the bouquet of semiochemicals are responsible for the outcome of different biological processes, such as mate finding, egg-laying site recognition and host selection. The volatiles present in phloem samples of four pine species, P. halepensis, P. sylvestris, P. pinaster and P. pinea, were identified and characterized with the aim of finding possible host-plant attractants for native pests, such as the bark beetle Tomicus piniperda. The volatile compounds emitted by phloem samples of pines were extracted by headspace solid-phase micro extraction, using a 2 cm 50/30 mm divinylbenzene/carboxen/polydimethylsiloxane table flex solid-phase microextraction fiber and its contents analyzed by high-resolution gas chromatography, using flame ionization and a non polar and chiral column phases. The components of the volatile fraction emitted by the phloem samples were identified by mass spectrometry using time-of-flight and quadrupole mass analyzers. The estimated relative composition was used to perform a discriminant analysis among pine species, by means of cluster and principal component analysis. It can be concluded that it is possible to discriminate pine species based on the monoterpenes emissions of phloem samples

Nutritional characteristics and minerals of Lardosa cowpea landraces : a strategic legume species for the future

Cowpeas have been cultivated at least since the 8th century BC. [1; 2]. This grain legume (Vigna unguiculata L. Walp.), one of Africa's natural food gifts to the world, is characterized by its high nutritional value, ability to fix nitrogen and great tolerance to drought. The tolerance of this legume to low fertility soils, high temperatures and scarce water regimes makes this one of the most resistant crops to adverse edaphoclimatic conditions. It is certainly a very important culture in southern European countries like Portugal.Cultivar-Rede de competências para o desenvolvimento sustentável e inovação no setor Agroalimentar (CENTRO-01-0145-FEDER-000020).info:eu-repo/semantics/publishedVersio

Novel product using a native breed of sheep (Merino da Beira Baixa): smoked lamb

Merino breed emerged, in the textile industry renowned for their high-quality wool. This work aims to develop a novel food product. In Castelo Branco the “Merino da Beira Baixa” is part of 3 PDO cheeses and a PGI meat “Amarelo”, “Picante” e “Castelo Branco” and “Borrego da Beira”.The breed has experienced a decline in influence due to plummeting wool prices and an inability to compete with more productive breeds. This work aims to develop a novel food product using a ancestral breed and technique (smoking).Fusili European Union's Horizon 2020 under grant agreement n.º 101000717.info:eu-repo/semantics/publishedVersio

Measurement of the cross section for isolated-photon plus jet production in pp collisions at √s=13 TeV using the ATLAS detector

The dynamics of isolated-photon production in association with a jet in proton–proton collisions at a centre-of-mass energy of 13 TeV are studied with the ATLAS detector at the LHC using a dataset with an integrated luminosity of 3.2 fb−1. Photons are required to have transverse energies above 125 GeV. Jets are identified using the anti- algorithm with radius parameter and required to have transverse momenta above 100 GeV. Measurements of isolated-photon plus jet cross sections are presented as functions of the leading-photon transverse energy, the leading-jet transverse momentum, the azimuthal angular separation between the photon and the jet, the photon–jet invariant mass and the scattering angle in the photon–jet centre-of-mass system. Tree-level plus parton-shower predictions from Sherpa and Pythia as well as next-to-leading-order QCD predictions from Jetphox and Sherpa are compared to the measurements

Orange snacks as a solution for orange surplus in Portugal

In the summer of 2022, Portugal experienced a downfall of the price of oranges, mainly due to pressure of the agricultural commodity market and the change in trade dynamics in Europe due to the war in Ukraine. One way to add value to a product is to transform it into something new.CULTIVAR (CENTRO-01-0145-FEDER-000020) e FUSILIinfo:eu-repo/semantics/publishedVersio

Development and characterization of an orange dehydrated crispy snack

Oranges are mainly consumed as fresh fruit, processed orange (mostly as juice) are global commodity. As a natural ingredient. As an edible topping. Ready-to-eat snack. Presence of vectors in chestnuts. Dried fruits are used as versatile foods, as snacks or as an ingredient to enrich other foods. One of the most appreciated proprieties of a snack is presenting a crunchy texture. This study aims to create a new product by dehydration of sweet oranges in an innovative format.Fusili European Union's Horizon 2020 under grant agreement n.º 101000717.info:eu-repo/semantics/publishedVersio
