La relación entre el porcentaje de cobertura y el uso de distintos tensioactivos fue analizada en este trabajo. Para ello se emplearon dos productos (alcohol etoxilado y nonil fenol) de la firma Rizobacter Argentina S.A., con tres concentraciones de cada uno de ellos. Las determinaciones se efectuaron utilizando un equipo spray boot provisto con una pastilla de abanico plano (8015), a 300 kPa y a una altura de 0,58 m, alcanzando un caudal de campo de 78 litros por hectárea. Como blanco de la pulverización se colocaron tarjetas hidrosensibles y hojas de soja (Glycine max L.). Las muestras se ubicaron en un microscopio óptico y se procedió a fotografiarlas, para luego ser digitalizadas y contabilizar, mediante el uso de un programa específico, la cantidad y el tamaño de los impactos y el grado de cobertura. Los resultados muestran que la cobertura alcanzada con agua sin tensioactivos, es significativamente menor en hojas de soja que en las tarjetas hidrosensibles, siendo inferior en ambos casos, a la obtenida con el agregado de los productos citados precedentemente. El porcentaje de cobertura se modificó en función de las concentraciones empleadas y de las distintas características de las superficies pulverizadas

Abstract The COHERENT collaboration observed coherent elastic neutrino nucleus scattering using a 14.6 kg cesium-iodide (CsI) detector in 2017 and recently published the updated results before decommissioning the detector. Here, we present the legacy determination of the weak mixing angle and of the average neutron rms radius of $$^{133}{\textrm{Cs}}$$ 133 Cs and $$^{127}{\textrm{I}}$$ 127 I obtained with the full CsI dataset, also exploiting the combination with the atomic parity violation (APV) experimental result, that allows us to achieve a precision as low as $$\sim $$ ∼ 4.5% and to disentangle the contributions of the $$^{133}{\textrm{Cs}}$$ 133 Cs and $$^{127}{\textrm{I}}$$ 127 I nuclei. Interestingly, we show that the COHERENT CsI data show a 6 $$\sigma $$ σ evidence of the nuclear structure suppression of the full coherence. Moreover, we derive a data-driven APV+COHERENT measurement of the low-energy weak mixing angle with a percent uncertainty, independent of the value of the average neutron rms radius of $$^{133}{\textrm{Cs}}$$ 133 Cs and $$^{127}{\textrm{I}},$$ 127 I , that is allowed to vary freely in the fit. Additionally, we extensively discuss the impact of using two different determinations of the theoretical parity non-conserving amplitude in the APV fit. Our findings show that the particular choice can make a significant difference, up to 6.5% on $$R_n$$ R n (Cs) and 11% on the weak mixing angle. Finally, in light of the recent announcement of a future deployment of a 10 kg and a $$\sim $$ ∼ 700 kg cryogenic CsI detectors, we provide future prospects for these measurements, comparing them with other competitive experiments that are foreseen in the near future.

Sub clinical mastitis may cause more losses than clinical mastitis. Farmers can take advantage of employing several tools, California Mastitis Test (CMT) and Somatic Cell Count (SCC) among the others, to determine the presence of a sub clinical mastitis in their herds. The aim of the present study was to evaluate the microbiological quality of milk produced in some extensive goat herds in Sardinia through a clinical check to determine the infection status of the udder, CMT, SCC and microbiological milk tests. CMT has been confirmed to be a useful, practical and economical tool to detect sub clinical mastitis in goats. Farmers should be encouraged to use this as a first step in order to avoid prospective losses in their herds.
