Evolution of Global Ocean Tide Levels Since the Last Glacial Maximum

This study addresses the evolution of global tidal dynamics since the Last Glacial Maximum focusing on the extraction of tidal levels that are vital for the interpretation of geologic sea-level markers. For this purpose, we employ a truly-global barotropic ocean tide model which considers the non-local effect of Self-Attraction and Loading. A comparison to a global tide gauge data set for modern conditions yields agreement levels of 65%–70%. As the chosen model is data-unconstrained, and the considered dissipation mechanisms are well understood, it does not have to be re-tuned for altered paleoceanographic conditions. In agreement with prior studies, we find that changes in bathymetry during glaciation and deglaciation do exert critical control over the modeling results with minor impact by ocean stratification and sea ice friction. Simulations of 4 major partial tides are repeated in time steps of 0.5–1 ka and augmented by 4 additional partial tides estimated via linear admittance. These are then used to derive time series from which the tidal levels are determined and provided as a global data set conforming to the HOLSEA format. The modeling results indicate a strengthened tidal resonance by M2, but also by O1, under glacial conditions, in accordance with prior studies. Especially, a number of prominent changes in local resonance conditions are identified, that impact the tidal levels up to several meters difference. Among other regions, resonant features are predicted for the North Atlantic, the South China Sea, and the Arctic Ocean

HOMEOPATHIC PRODUCT IN DOG DIETS MODULATE BLOOD CELL RESPONSES

Every year, numbers and life expectancies of pets increase, especially for dogs and cats. Pets are exposed to environmental factors such as pollutants, pathogens, and oxidants that hamper the animals’ ability to respond to stressors. Nutrition and hygiene are increasingly important among animal professionals and pet owners. The objective of this study was to evaluate the efficacy of a commercially-available homeopathic herbal product formulated with plants, designed to stimulate canine immunity. We used 10 male dogs (beagles) weighing 5.5–6 kg and 5 months of age. Animals were randomly allocated to Control (C, n = 5) and Treated (T, n = 5) groups. The treated group received a basal diet with an additional dose of 0.5 mL/animal/day homeopathic solution and group C received only the basal diet (300 g/day). The product was supplied for 45 days. The animals were weighed and blood samples collected for complete blood counts and serum biochemistry on days 1, 15, 30 and 45 of the experiment. Higher numbers of lymphocytes were observed in conjunction with lower numbers of neutrophils in the T group on days 30 and 45. Total and neutrophil leukocytes decreased throughout the experiment in both groups, and lymphocytes increased with significant difference only in the T group. Erythrocytes and hematocrit increased in both groups over time, as did glucose, triglycerides, total protein, albumin and urea levels. ALT was higher in the control group on day 45. We conclude that the use of a homeopathic agent stimulated lymphocyte production in healthy dogs; and this suggests that homeopathic use is beneficial, because lymphocytes are directly related to cellular and humoral immune responses. Studies in adult animals and those focusing on infectious challenges may reveal more information about the actions of this homeopathic agent

Variabilidade espacial e temporal da produtividade de culturas sob sistema plantio direto.

O objetivo deste trabalho foi avaliar a variabilidade espacial e temporal da produtividade de soja, milho e trigo, em uma lavoura comercial de 57 ha, não irrigada, manejada há mais de dez anos sob sistema plantio direto, em um Latossolo Vermelho distrófico típico, em Palmeira das Missões, RS. A coleta de dados de produtividade de seis cultivos, entre 2000 e 2005, foi realizada por colhedora equipada com monitor de produtividade. Análises estatísticas e geoestatísticas foram realizadas a fim de avaliar a variabilidade espacial e a presença de dependência espacial ao longo dos anos. A produtividade da soja, do milho e do trigo alcançada apresenta variabilidade com continuidade espacial, correlacionando-se entre si, ao longo dos anos. Em anos de deficit hídrico, verifica-se aumento da variabilidade espacial da produtividade. A cultura do milho é mais eficiente do que a da soja em detectar a variabilidade espacial da produtividade existente na lavoura

Characterization of oxygen self-diffusion in TiO2 resistive-switching layers by nuclear reaction profiling

Oxygen self-diffusion was investigated in TiO2 layers employed for resistive-switching memories using resonant nuclear reaction profiling (NRP) and 18O labeling. The layers were grown using physical vapor deposition technique (sputtering) and were polycrystalline. The diffusivity was measured over the temperature range 600–800 °C and the activation energy for oxygen self-diffusion in sputter-deposited TiO2 films determined to be 1.09 ± 0.16 eV, a value consistent with results obtained by previous studies (Marmitt et al., 2017).This study was financed in part by the Coordena de Aperfei oamento de Pessoal de Nvel Superior – Brasil (CAPES) – Finance Code 001, by CNPq and PRONEX-FAPERGS.
