The Brans-Dicke-Rastall theory

We formulate a theory combining the principles of a scalar-tensor gravity and Rastall's proposal of a violation of the usual conservation laws. We obtain a scalar-tensor theory with two parameters $\omega$ and $\lambda$, the latter quantifying the violation of the usual conservation laws. The only exact spherically symmetric solution is that of Robinson-Bertotti besides Schwarzschild solution. A PPN analysis reveals that General Relativity results are reproduced when $\lambda = 0$. The cosmological case displays a possibility of deceleration/acceleration or acceleration/deceleration transitions during the matter dominated phase depending on the values of the free parameters.Comment: 17 pages, 3 figure

Longe dos partidos e perto da federação: uma avaliação dos gastos municipais na saúde pública

The institutionalization of SUS made the municipalities important players in the public health policy. Thus, it was expected that the amount of resources allocated to public health would be determinate in some measure by the political party preferences. Given these political and institutional contexts, we analyzed the importance of the political party policies at the municipality level as a determinant of the expenditure on public health, as well was other conventional determinants of the expenditures on public health (region, per capita income, GDP, etc). Applying some econometric techniques (quantile regressions and econometric decomposition), we found that the parties’ political preferences have minor influence on the allocation of resources in public health. We conclude that the constitutional regulation (Constitutional Emend 29 or EC29) seems to be a more important determinant to explain the allocation of resources in the period 2002-2006 than the supposed political preferences announced by parties.SUS, health economics, Brazil

Monogamy of Quantum Discord by Multipartite Correlations

We introduce a monogamy inequality for quantum correlations, which implies that the sum of pairwise quantum correlations is upper limited by the amount of multipartite quantum correlations as measured by the global quantum discord. This monogamy bound holds either for pure or mixed quantum states provided that bipartite quantum discord does not increase under discard of subsystems. We illustrate the monogamy behavior for multipartite pure states with Schmidt decomposition as well as for W-GHZ mixed states. As a by-product, we apply the monogamy bound to investigate residual multipartite correlations.Comment: 5 pages, 2 figures. v2: published versio

Tomate sweet grape cultivado em substratos de cultivo e efluente com complementação de nutrientes

O objetivo do trabalho foi avaliar a produção do minitomate (Lycopersicum esculentum Mill.) variedade Sweet Grape, empregando substratos de cultivo e solução nutritiva de efluente de esgoto, aplicada por gotejamento. O experimento foi realizado na Universidade Estadual de Goiás (UEG-UnUCET), de junho a novembro de 2011 em Anápolis, Goiás. O delineamento experimental foi em esquema fatorial 2 x 3, em blocos casualizados, com quatro repetições. As parcelas foram constituídas pela combinação de duas soluções nutritivas, efluente complementado com fertilizantes minerais - EcS e solução nutritiva convencional - SnC, e três substratos de cultivo, com 60% de areia fina lavada + 40% de substrato composto de 20% de fibra de coco e 80% de casca de pínus (S1); 20% de fibra de coco e 80% de casca de pínus (S2) e fibra de coco natural (S3). No efluente de esgoto, foram avaliados nitrato, cálcio, potássio, manganês, fosfato total, ferro total, magnésio, cloreto, sulfato, boro, zinco e molibdênio. Avaliaram-se a massa média e o número médio de frutos por cacho, o número total de frutos e a produção total por planta. A ausência de diferença estatística entre as soluções testadas indica que o efluente de esgoto pode ser utilizado como fonte alternativa de nutrientes no cultivo do minitomate em hidroponia.The objective of this study was to evaluate production of Sweet Grape mini tomato (Lycopersicum esculentum Mill.) using culture substrates and nutrient solution sewage effluent, applied by drip irrigation (fertigation). The experiment was conducted at the University of Goiás State (UEG-UnUCET), from June to November 2011 in Anápolis-GO, Brazil. The experimental design was a 2 x 3 factorial arrangement in a randomized complete block design with four repetitions. The plots were made by combining two nutrient solutions, effluent supplemented with mineral fertilizers (EcS); conventional nutrient solution (SnC); in addition three cultivation substrates: 60% of fine sand washed + 40% substrate composed by 20% coconut fiber plus 80% pine bark (S1); 20% coconut fiber and 80% pine bark (S2) and natural coconut fiber (S3). Sewage effluent were determined nitrate, calcium, potassium, manganese, total phosphate, total iron, magnesium, chloride, sulphate, boron, zinc and molybdenum. We evaluated average mass and average number of fruits per bunch, total fruit and total yield per plant. Statistical difference absence among tested solutions indicates sewage effluent can be used as an alternative source of nutrients in growing mini tomatoes in hydroponics

Communication: Transient Anion States Of Phenol…(h₂o)n (n = 1, 2) Complexes: Search For Microsolvation Signatures.

We report on the shape resonance spectra of phenol-water clusters, as obtained from elastic electron scattering calculations. Our results, along with virtual orbital analysis, indicate that the well-known indirect mechanism for hydrogen elimination in the gas phase is significantly impacted on by microsolvation, due to the competition between vibronic couplings on the solute and solvent molecules. This fact suggests how relevant the solvation effects could be for the electron-driven damage of biomolecules and the biomass delignification [E. M. de Oliveira et al., Phys. Rev. A 86, 020701(R) (2012)]. We also discuss microsolvation signatures in the differential cross sections that could help to identify the solvated complexes and access the composition of gaseous admixtures of these species.14105110

Dipeptidyl peptidase IV inhibition upregulates GLUT4 translocation and expression in heart and skeletal muscle of spontaneously hypertensive rats

The purpose of the current study was to test the hypothesis that the dipeptidyl peptidase IV (DPPIV) inhibitor sitagliptin, which exerts anti-hyperglycemic and anti-hypertensive effects, upregulates GLUT4 translocation, protein levels, and/or mRNA expression in heart and skeletal muscle of spontaneously hypertensive rats (SHRs). Ten days of treatment with sitagliptin (40 mg/kg twice daily) decreased plasma DPPIV activity in both young (Y, 5-week-old) and adult (A, 20-week-old) SHRs to similar extents ( similar to 85%). However, DPPIV inhibition only lowered blood pressure in Y-SHRs (119 +/- 3 vs. 136 +/- 4 mmHg). GLUT4 translocation, total protein levels and mRNA expression were decreased in the heart, soleus and gastrocnemius muscle of SHRs compared to age-matched Wistar Kyoto (WKY) normotensive rats. These differences were much more pronounced between A-SHRs and A-WKY rats than between Y-SHRs and Y-WKY rats. in Y-SHRs, sitagliptin normalized GLUT4 expression in the heart, soleus and gastrocnemius. in A-SHRs, sitagliptin increased GLUT4 expression to levels that were even higher than those of A-WKY rats. Sitagliptin enhanced the circulating levels of the DPPIV substrate glucagon-like peptide-1 (GLP-1) in SHRs. in addition, stimulation of the GLP-1 receptor in cardiomyocytes isolated from SHRs increased the protein level of GLUT4 by 154 +/- 13%. Collectively, these results indicate that DPPIV inhibition upregulates GLUT4 in heart and skeletal muscle of SHRs. the underlying mechanism of sitagliptin-induced upregulation of GLUT4 in SHRs may be, at least partially, attributed to GLP-1.

3‑Aminopropyl-triethoxysilane-Functionalized Tannin-Rich Grape Biomass for the Adsorption of Methyl Orange Dye: Synthesis, Characterization, and the Adsorption Mechanism

A biomass amino silica-functionalized material was successfully prepared by a simple sol–gel method. 3-Aminopropyltriethoxysilane (APTES) was added to a tannin-rich grape residue to improve its physicochemical properties and enhance the adsorption performance. The APTES functionalization led to significant changes in the material’s characteristics. The functionalized material was efficiently applied in the removal of methyl orange (MO) due to its unique characteristics, such as an abundance of functional groups on its surface. The adsorption process suggests that the electrostatic interactions were the main acting mechanism of the MO dye removal, although other interactions can also take place. The functionalized biomass achieved a very high MO dye maximum adsorption capacity (Qmax) of 361.8 mg g–1. The temperature positively affected the MO removal, and the thermodynamic studies indicated that the adsorption of MO onto APTES-functionalized biomass was spontaneous and endothermic, and enthalpy is driven in the physisorption mode. The regeneration performance revealed that the APTES-functionalized biomass material could be easily recycled and reused by maintaining very good performance even after five cycles. The adsorbent material was also employed to treat two simulated dye house effluents, which showed 48% removal. At last, the APTES biomass-based material may find significant applications as a multifunctional adsorbent and can be used further to separate pollutants from wastewater
