Ramirez M., Jorge A.
Publicado 2016 Enlace
La Responsabilidad Social Empresarial (RSE) ha adquirido un relevante protagonismo en los últimos años como signo del compromiso de la empresa con sus distintos grupos de interés, la empresa socialmente responsable debe ser consciente que su accionar puede ocasionar impactos a cualquier individuo o grupo de interés. A nivel científico se ha demostrado que la RSE influye de forma positiva sobre los resultados financieros de las empresas de gran nivel, pero no se ha estudiado su impacto sobre la competitividad, una variable que tiene gran interés para los directivos de empresas por su repercusión a nivel estratégico e integral y su consiguiente implicación en el desarrollo de cualquier sector empresarial más aún si esta se trata de una Mipyme. Por otro lado, a pesar del importante peso relativo que en la economía tienen las Mipymes, y su tratamiento diferenciado a la hora de di...

Gold mining is the largest source of mercury (Hg) pollution worldwide. The discharge of mercury in the environment bears direct human health risks and is likely to increase cascading effects throughout local food chains. In the Peruvian Amazon the mining process consists of slashing and burning trees, followed by extraction of gold-bearing sediment, amalgamation with Hg and gold recovery, leading each year to the degradation of 6,000-10,000 ha and the release of 180 metric tons of Hg per year to the enviroment. The purpose of this study was to determine soil Hg levels in soils of abandoned alluvial gold mine spoils and undisturbed forest in the Madre de Dios region, the epicenter of alluvial gold mining in Peru. We selected gold mine spoils of the two most important technologies locally applied for gold extraction, i.e., Minimally Mechanized Mining (MMM) and Highly Mechanized Mining (HMM...

Mazzaella canaliculata comb. nov. based on Chondrus canaliculatus (Gigartinaceae, Rhodophyta) from Peru and Chile
Publicado por
Arakaki N., Ramirez M.E.
Publicado 2021 Enlace
Chondrus canaliculatus is a red seaweed endemic to Peru and Chile. The name currently represents the only species classified in Chondrus from the southern hemisphere. Based on previous phylogenetic analyses, C. canaliculatus is polyphyletic with respect to Chondrus and possesses unique morpho-anatomical features that distinguish it from other genera in the Gigartinaceae. In this study, expanded phylogenetic analyses using rbcL and COI sequences, a combined data set, and morphological details were further examined to address the taxonomy and evolutionary systematics of C. canaliculatus. Genetic analyses placed C. canaliculatus well within the genus Mazzaella and therefore Mazzaella canaliculata comb. nov. is proposed. Mazzaella canaliculata is distinguished from the other Mazzaella from the southern hemisphere by its dichotomous branching, secondary filaments that persist and leave a well...

Publicado 2019 Enlace
Seven species of Rhodymenia have been recorded for the coast of Peru, where six of them grow on the central coast: R. corallina, R. howeana, R. multidigitata, R. flabellifolia, R. skottsbergii and R. californica. The most controversial taxonomically is R. corallina, from which R. howeana and R. multidigitata have been separated, only on the basis of external morphological characters (stipe form and frond habit). Recent and intensive collections of this species complex in the central coast of Peru (9°S to 15°S) have allowed gathering several morphotypes, evidencing high morphological variability, which makes difficult to differentiate each of the taxa involved. The aim of this work was to clarify the taxonomy of this complex by combining morphological data, both vegetative and reproductive, and genetic sequences through the use of rbcL and COI-5P markers. Specimens from Callao, type loc...

Publicado 2020 Enlace
Phyllophorella was recently described from two localities on the central coast of Peru (12°S), based on the endemic species Phyllophora (Ph.) peruviana. The genus currently accommodates three species, Phyllophorella (P.) peruviana, P. humboldtiana and P. limaensis. Recent field surveys for Phyllophorella on the central coast of Peru led to the discovery of collections outside the originally reported ranges. Morphological, anatomical, and genetic characterization of the specimens confirms range extensions for P. peruviana to 9° S and 15° S, and P. humboldtiana to 12° S and 15° S. A combined phylogenetic analysis of rbcL and COI-5P gene sequences supports the taxonomic status of these two species and reasserts the genus as monophyletic. Anatomically, the two species differ in nemathecial structure. Phyllophorella peruviana displays dome-shaped and well-defined circular nemathecia, whe...

Publicado 2020 Enlace
The aim of this study was to determine the programmes of parasite and sanitary control and knowledge of the parasite diseases that affect dogs and cats of 306 owners of the city of Escárcega, state of Campeche, Mexico. The total number of pets was 590 dogs and 149 cats. Each household has an average of 1.92 dogs or 0.48 cats with ages of 2.9 and 2.8 years, respectively. Most owners of dogs (30.8%) and cats (25.6%) apply some anthelmintic treatment twice a year. The frequency of treatments against ectoparasites in dogs and cats is carried out mostly four times a year or when their presence is detected. Gastrointestinal parasites are poorly known, and scabies is the most mentioned disease. Most owners of dogs (85.6%) and cats (93%) are unaware of the meaning of zoonosis and that their pets can transmit diseases to them, suggesting its low impact on health management in pets.

Charged-current νμ interactions on carbon, iron, and lead with a final state hadronic system of one or more protons with zero mesons are used to investigate the influence of the nuclear environment on quasielasticlike interactions. The transferred four-momentum squared to the target nucleus, Q2, is reconstructed based on the kinematics of the leading proton, and differential cross sections versus Q2 and the cross-section ratios of iron, lead, and carbon to scintillator are measured for the first time in a single experiment. The measurements show a dependence on the atomic number. While the quasielasticlike scattering on carbon is compatible with predictions, the trends exhibited by scattering on iron and lead favor a prediction with intranuclear rescattering of hadrons accounted for by a conventional particle cascade treatment. These measurements help discriminate between different mod...

The semiexclusive channel νμ þ CH → μ−π0 þ nucleonðsÞ is analyzed using MINERvA exposed to the low-energy NuMI νμ beam with spectral peak at Eν ≃ 3 GeV. Differential cross sections for muon momentum and production angle, π0 kinetic energy and production angle, and for squared four-momentum transfer are reported, and the cross section σðEνÞ is obtained over the range 1.5 GeV ≤ Eν < 20 GeV. Results are compared to GENIE and NuWro predictions and to published MINERvA cross sections for charged-current πþðπ0Þ production by νμðν¯μÞ neutrinos. Disagreements between data and simulation are observed at very low and relatively high values for muon angle and for Q2 that may reflect shortfalls in modeling of interactions on carbon. For π0 kinematic distributions, however, the data are consistent with the simulation and provide support for generator treatments o...

The total cross sections are important ingredients for the current and future neutrino oscillation experiments. We present measurements of the total charged-current neutrino and antineutrino cross sections on scintillator (CH) in the NuMI low-energy beamline using an in situ prediction of the shape of the flux as a function of neutrino energy from 2–50 GeV. This flux prediction takes advantage of the fact that neutrino and antineutrino interactions with low nuclear recoil energy (ν) have a nearly constant cross section as a function of incident neutrino energy. This measurement is the lowest energy application of the low-ν flux technique, the first time it has been used in the NuMI antineutrino beam configuration, and demonstrates that the technique is applicable to future neutrino beams operating at multi-GeVenergies. The cross section measurements presented are the most precise mea...

Neutrino induced coherent charged pion production on nuclei, ν¯μA → μ π∓A, is a rare inelastic interaction in which the four-momentum squared transferred to the nucleus is nearly zero, leaving it intact. We identify such events in the scintillator of MINERvA by reconstructing jtj from the final state pion and muon momenta and by removing events with evidence of energetic nuclear recoil or production of other final state particles. We measure the total neutrino and antineutrino cross sections as a function of neutrino energy between 2 and 20 GeV and measure flux integrated differential cross sections as a function of Q2, Eπ, and θπ. The Q2 dependence and equality of the neutrino and antineutrino cross sections at finite Q2 provide a confirmation of Adler’s partial conservation of axial current hypothesis.

Muon-neutrino elastic scattering on electrons is an observable neutrino process whose cross section is precisely known. Consequently a measurement of this process in an accelerator-based νμ beam can improve the knowledge of the absolute neutrino flux impinging upon the detector; typically this knowledge is limited to ∼10% due to uncertainties in hadron production and focusing. We have isolated a sample of 135±17 neutrino-electron elastic scattering candidates in the segmented scintillator detector of MINERvA, after subtracting backgrounds and correcting for efficiency. We show how this sample can be used to reduce the total uncertainty on the NuMI νμ flux from 9% to 6%. Our measurement provides a flux constraint that is useful to other experiments using the NuMI beam, and this technique is applicable to future neutrino beams operating at multi-GeV energies. © 2016 American Physic...

Final-state kinematic imbalances are measured in mesonless production of νμ þ A → μ− þ p þ X in the MINERvA tracker. Initial- and final-state nuclear effects are probed using the direction of the μ−-p transverse momentum imbalance and the initial-state momentum of the struck neutron. Differential cross sections are compared to predictions based on current approaches to medium modeling. These models underpredict the cross section at intermediate intranuclear momentum transfers that generally exceed the Fermi momenta. As neutrino interaction models need to correctly incorporate the effect of the nucleus in order to predict neutrino energy resolution in oscillation experiments, this result points to a region of phase space where additional cross section strength is needed in current models, and demonstrates a new technique that would be suitable for use in fine-grained liquid a...
