Growth, Yield, And Postharvest Quality In Eggplant Produced Under Different Foliar Fertilizer (spirulina Platensis) Treatments

This study evaluated the growth, yield, and postharvest quality of eggplant grown under different foliar fertilizer treatments with Spirufert® (Spirulina platensis). The treatments consisted of four fertilizer concentrations applied at four phenological stages: M1 (10, 15, 25, and 35 g L-1), M2 (15, 20, 30, and 40 g L-1), M3 (20, 25, 35, and 45 g L-1), and M4 (control plants, water spraying only). For Postharvest experiments were conducted in a 4 x 5 factorial design corresponding to the four treatments in the field experiment and five storage times. Spirufert® applied at lower concentrations (M1) resulted in greater fruit yield without affecting the foliar concentrations of N, P, K, and Na. Higher fertilizer concentrations (M3) increased vegetative growth but reduced eggplant yield. Fruit color parameters and soluble solids contents were not affected by fertilizer application, but pulp firmness was more stable in M1 fruits stored for up to six days.3763893390

Validation of spallation neutron production and propagation within Geant4

Using simulations to understand backgrounds from muon-induced neutrons is important in designing next-generation low-background underground experiments. Validation of relevant physics within the Geant4 simulation package has been completed by comparing to data from two recent experiments. Verification focused on the production and propagation of neutrons at energies important to underground experiments. Discrepancies were observed between experimental data and the simulation. Techniques were explored to correct for these discrepancies.Comment: 12 pages, 6 figures, 5 tables, submitted to NIM A. 6 Aug 200

Robust exponential decay of correlations for singular-flows

We construct open sets of Ck (k bigger or equal to 2) vector fields with singularities that have robust exponential decay of correlations with respect to the unique physical measure. In particular we prove that the geometric Lorenz attractor has exponential decay of correlations with respect to the unique physical measure.Comment: Final version accepted for publication with added corrections (not in official published version) after O. Butterley pointed out to the authors that the last estimate in the argument in Subsection 4.2.3 of the previous version is not enough to guarantee the uniform non-integrability condition claimed. We have modified the argument and present it here in the same Subsection. 3 figures, 34 page

CARACTERIZAÇÃO DOS RESÍDUOS DAS INDÚSTRIAS CERÂMICAS ESTRUTURAIS DA REGIÃO DO CARIRI – CE

Existe uma grande preocupação por parte das indústrias com a disposição dos resíduos gerados ao longo do processo produtivo, e no setor de cerâmica estrutural não é diferente. O descarte desses resíduos, de um modo geral, ocasiona um impacto ambiental negativo. Assim, o presente trabalho tem por objetivo analisar os resíduos produzidos pelas indústrias cerâmicas estruturais da região do Cariri – CE, para fins de reutilização. A caracterização dos resíduos foi realizada antes e após queima para três produtos distintos: lajota, tijolo de 8 furos e telha romana, por meio das técnicas de difração de raios–X (DRX), Espectroscopia vibracional na região do infravermelho (IV), análise térmica diferencial (ATD), análise térmica gravimétrica (ATG) e fluorescência de raios-X. Com base nos resultados de DRX (após queima) pode-se concluir que as amostras são resíduos principalmente constituídos de quartzo (SiO2) em maior quantidade e feldspato e rutilo em menor quantidade, confirmados através dos espectros de infravermelho, assim como, é possível observar na fluorescência de raios-X concentrações mais altas de SiO2, a presença de Fe2O3 que caracteriza a cor avermelha nos resíduos, além de outros óxidos como Al2O3, CaO, Na2O, K2Oe TiO2. Os resultados preliminaresmostram que os resíduos estudados podem ser incorporados a uma matriz cerâmica

Proteínas do citoesqueleto na parede folicular de ovários normais e císticos de porcas matrizes

The expression of cytoskeletal proteins was evaluated immunohistochemically in 36 normal ovaries sampled from 18 sows and 44 cystic ovaries sampled from of 22 sows, was evaluated. All sows had history of reproductive problems, such as infertility or subfertility. The immunohistochemically stained area (IHCSA) was quantified through image analysis to evaluate the expression of these proteins in the follicular wall of secondary, tertiary, and cystic follicles. Cytokeratins (CK) immunoreactivity was strong in the granulosa cell layer (GC) and mild in the theca interna (TI) and externa (TE) of the normal follicles. There was severe reduction of the reaction to CK in the GC in the cystic follicles, mainly in the luteinized cysts. The immunoreactivity for vimentin was higher in the GC from normal and cystic follicles in contrast with the other follicular structures. In the luteinized cysts, the IHCSA for vimentin was significantly higher in TI and in both observed cysts, the labeling was more accentuated in TE. Immunohistochemical detection of desmin and α-SMA was restricted to the TE, without differences between the normal and cystic follicles. The results of the current study show that the development of ovarian cysts in sows is associated to changes in the expression of the cytoskeletal proteins CK and vimentin.A expressão de proteínas do citoesqueleto foi avaliada por imuno-histoquímica em ovários normais e císticos de porcas matrizes. Amostras de 36 ovários normais (18 porcas) e de 44 císticos (22 porcas) foram avaliadas. Todas as matrizes apresentaram histórico de problemas reprodutivos, como infertilidade ou subfertilidade. As áreas coradas por imuno-histoquímica (IHCSA) foram quantificadas por avaliação de imagens avaliando a expressão dessas proteínas na parede folicular de folículos secundários, terciários e císticos. A imuno-reatividade para citoqueratina (CK) foi forte na camada de células da granulosa (GC) e discreta nas tecas interna (TI) e externa (TE) dos folículos normais. Houve redução acentuada da reação de CK na CG dos folículos císticos, principalmente nos cistos luteinizados. A reação para vimentina foi mais intensa na CG dos folículos normais e císticos em comparação com outras estruturas foliculares. Nos cistos luteinizados, a IHCSA para vimentina foi significativamente maior na TI e, em ambos os cistos observados, a marcação foi mais acentuada na TE. A marcação de desmina e actina alfa de músculo liso foi restrita a TE, sem diferenças entre os folículos normais e císticos. Os resultados do presente estudo mostram que o desenvolvimento de cistos ovarianos em porcas matrizes está associado a alterações na expressão das proteínas do citoesqueleto CK e vimentina.Facultad de Ciencias Veterinaria

A Raman Study of Morphotropic Phase Boundary in PbZr1-xTixO3 at low temperatures

Raman spectra of PbZr1-xTixO3 ceramics with titanium concentration varying between 0.40 and 0.60 were measured at 7 K. By observing the concentration-frequency dependence of vibrational modes, we identified the boundaries among rhombohedral, monoclinic, and tetragonal ferroelectric phases. The analysis of the spectra was made in the view of theory group analysis making possible the assignment of some modes for the monoclinic phase.Comment: 5 pages, 4 figure

Prediction of body weight of Brown Alpine goats by measuring body volume

ABSTRACT The objective was to estimate the body weight (BW) of Brown Alpine goats by means of body volume (BV) measurements. We used 132 pieces of information with measurements of BW, body length (BL) and thoracic perimeter (TP) from 22 goats evaluated fortnightly, between March and May 2023. Based on this information, the BV of the animals was calculated. Three mathematical models were evaluated - a linear model, a quadratic model, and an exponential model - with the measurement of BV. The goodness of fit of the equations was evaluated using the coefficient of determination (R2), mean square error (MSE) and root of the MSE (RMSE). The predictive ability of the models was evaluated by k-fold cross-validation (k = 10). A high positive correlation between BW and TP (r = 0.95) and BL (r = 0.94) was observed. The correlation between BW and BV was higher than the other correlations (r = 0.98). The linear model showed the lowest values of MSE (9.49) and RMSE (3.08). In the cross-validation, the linear and quadratic models presented estimates of the mean BW and the standard deviation of this weight similar to the real data, and high R2 values (0.95) of the data predicted by the observed ones. The analysis of the coefficient of correlation and concordance (CCC) also showed that these models have accuracy and precision (CCC > 0.95). Thus, the linear and quadratic models estimate the body weight of Brown Alpine goats with precision and accuracy
