Background: The ensiling process of sugarcane promotes yeast proliferation during fermentation, requiring the use of additives. Clitorea ternatea can be used as a natural additive in sugarcane ...silages to reduce dry matter losses and modifying the fermentation profile of the silage. Objective: To evaluate the fermentative profile, chemical composition, in vitro gas production and ruminal degradation kinetics of sugarcane silages associated with different levels of butterfly pea hay. Methods: Increasing levels of butterfly pea hay (0, 10, 20, and 30% on dry matter basis) were added to sugarcane silages. A completely randomized design was adopted, with four treatments and four repetitions, totaling 16 experimental silos that were opened after 60 days of ensiling. Results: Positive changes were observed in terms of fermentative losses, fermentative profile, chemical composition, in vitro gas production, and ruminal degradation kinetics with the addition of butterfly pea hay to sugarcane silage (p<0.05). Conclusion: The inclusion of up to 20% butterfly pea hay in sugarcane silage reduces fermentation losses and improves silage quality, such as increase in protein and energy content and reduction of the fibrous fractions of the silage, making silage an excellent ingredient to be included in ruminant diets.

On a finite momentum grid with N integration points pn and weights wn (n=1,…,N) the Similarity Renormalization Group (SRG) with a given generator G unitarily evolves an initial interaction with a ...cutoff λ on energy differences, steadily driving the starting Hamiltonian in momentum space Hn,m0=pn2δn,m+Vn,m to a diagonal form in the infrared limit (λ→0), Hn,mG,λ→0=Eπ(n)δn,m, where π(n) is a permutation of the eigenvalues En which depends on G. Levinson's theorem establishes a relation between phase-shifts δ(pn) and the number of bound-states, nB, and reads δ(p1)−δ(pN)=nBπ. We show that unitarily equivalent Hamiltonians on the grid generate reaction matrices which are compatible with Levinson's theorem but are phase-inequivalent along the SRG trajectory. An isospectral definition of the phase-shift in terms of an energy-shift is possible but requires in addition a proper ordering of states on a momentum grid such as to fulfill Levinson's theorem. We show how the SRG with different generators G induces different isospectral flows in the presence of bound-states, leading to distinct orderings in the infrared limit. While the Wilson generator induces an ascending ordering incompatible with Levinson's theorem, the Wegner generator provides a much better ordering, although not the optimal one. We illustrate the discussion with the nucleon–nucleon (NN) interaction in the S01 and S13 channels.
The subtracted kernel approach is shown to be a powerful method to be implemented recursively in scattering equations with regular plus point-like interactions. The advantages of the method allows ...one to recursively renormalize the potentials, with higher derivatives of the Dirac-delta, improving previous results. The applicability of the method is verified in the calculation of the S01 nucleon–nucleon phase-shifts, when considering a potential with one-pion-exchange plus a contact interaction and its derivatives. The S01 renormalization parameters are fitted to the data. The method can in principle be extended to any derivative order of the contact interaction, to higher partial waves and to coupled channels.

Sacha Inchi (Plukenetia huayllabambana), an oleoleguminosae with a high content ω-3, could help normalize alterations of obesity. We evaluated the effect of emulsion of Sacha Inchi (SI) oil on the lipid profile, oxidative stress and inflammation in serum and liver tissue of obesity-induced rats. Five groups induced to obesity by high-fat diet were analyzed. One group without treatment, two groups with the emulsion of SI oil (OSI1:0.25 ω-3/day, OSI2:0.5 ω-3/day), one group with atorvastatin and one group with atorvastatin plus the emulsion of SI oil. The treated groups lowered the values of total cholesterol, triglycerides, and LDLc, and increased HDLc. The lipid and protein oxidation marker, IL-6 and leptin decreased in serum, as well as TNF-α hepatic. In contrast, serum adiponectin, antioxidant capacity, and liver catalase activity increased in the OSI2 group. Therefore, the emulsion of SI oil normalizes the lipid profile and decreases oxidative stress and inflammation in an obesity model.
We analyze quantitatively the interplay between explicit and implicit renormalization in Nuclear Physics. By explicit renormalization we mean to integrate out higher energy modes below a given cutoff ...scale using the similarity renormalization group (SRG) with a block-diagonal evolution generator, which separates the total Hilbert-space into a model space and its complementary. In the implicit renormalization we impose given conditions at low energies for a cutoff theory. In both cases we compare the outcoming effective interactions as functions of the cutoff scale. We carry out a comprehensive analysis of a toy-model which captures the main features of the nucleon-nucleon () -wave interaction at low energies. We find a wide energy region where both approaches overlap. This amounts to a great simplification in the determination of the effective interaction. Actually, the outcoming scales are within the expected ones relevant for the physics of light nuclei.
Parkinson's disease (PD) is a neurological disorder resulting from the degeneration of black brain cells, compromising the autonomous movements of the human body. The signs and symptoms triggered by ...PD have negative consequences for the patient and his family, bringing greater demand to the health services. Thus, it is the responsibility of the health team, including the nursing team, to provide support to these patients. Therefore, it was aimed to identify the performance of the nurse of the PSF of the city of Lagarto-SE in the care given to these patients. This is a descriptive and qualitative research. Participants were 10 nurses from 09 Basic Health Units. Data were obtained through a questionnaire related to nursing care provided to patients with PD and their relatives. The qualitative data analysis was performed according to the Bardin content analysis steps. It was possible to observe only two records of patients with PD. It was noted that some of the interviewees are aware of the care that should be provided to these patients and their relatives, but they identify important flaws. It was also identified possible difficulties faced in the care of patients with PD and suggestions from the participants to improve this care.

The Nambu--Jona-Lasino model is modified by the inclusion of a running-coupling that was obtained by a fractal approach to Quantum Chromodynamics. The coupling follows a \(q\)-exponential function ...and, in the context of high energy collisions, explains the origin of the Tsallis non-extensive statistics distributions. The parameter \(q\) is completely determined in terms of the number of colours and the number of quark flavours. We study several aspects of the extended model and compare our results to the standard NJL model, where a constant coupling is used in combination with a sharp cutoff to regularize the gap equation. We show that the modified coupling regularizes the model like a smooth cutoff and reproduces the pion mass and decay constant, providing an almost exact Gell-Mann-Oakes-Renner relation at physical current quark masses.
The interest in the Klein-Gordon equation with different potentials has increased in recent years due to its possible applications in Cosmology, Hadron Physics and High-Energy Physics. In this work ...we investigate the solutions of the Klein-Gordon equation for bosons under the influence of an external potential by using the Feshbach-Villars method. We present detailed results for two cases: the Coulombic potential and the harmonic potential. For the latter case, we studied the effects of self-interacting particles by adopting a mean-field approach. We show that our results converge smoothly to the solution of the Schr\"odinger equation for the same systems as the relativistic effects diminish.
We study the Bose-Einstein condensation in non-extensive statistics for a free gas of bosons, and extend the results to the non-relativistic case as well. We present results for the dependence of the ...critical temperature and the condensate fraction on the entropic index, q, and show that the condensate can exist only for a limited range of q in both relativistic and non-relativistic systems. We provide numerical results for other thermodynamics quantities like the internal energy, specific heat and number fluctuations. We discuss the implications for high energy physics and hadron physics. The results for the non-relativistic case can be of interest in cold-atom systems.
