“…The BEAST is a 2.2‐m off‐axis Gregorian telescope (Figueiredo et al 2005) with a focal plane consisting of six Q band (38–45 GHz) and two Ka band (26–36 GHz) corrugated scalar feed horns coupled with cryogenic High Electron Mobility Transistor (HEMT) amplifiers (Childers et al 2005). The instrument was installed at the UC White Mountain Research Station at an altitude of 3.8 km in 2001 July.…”

We present the angular power spectrum of the cosmic microwave background (CMB) component extracted with fastica from the Background Emission Anisotropy Scanning Telescope (BEAST) data. BEAST is a 2.2‐m off‐axis telescope with a focal plane comprising eight elements at Q (38–45 GHz) and Ka (26–36 GHz) bands. It operates from the UC (University of California) White Mountain Research Station at an altitude of 3800 m. The BEAST CMB angular power spectrum has already been calculated by O'Dwyer et al. using only the Q‐band data. With two input channels, fastica returns two possible independent components. We found that one of these two has an unphysical spectral behaviour, while the other is a reasonable CMB component. After a detailed calibration procedure based on Monte Carlo (MC) simulations, we extracted the angular power spectrum for the identified CMB component and found a very good agreement with the already published BEAST CMB angular power spectrum and with the Wilkinson Microwave Anisotropy Probe (WMAP) data.

“…Since then, its pods have been used mainly as animal feed. 15 The physicochemical characterisation and in vitro digestibility and colonic fermentability of PJ samples from Peru, obtained by acid and roasting processes, were investigated. The gum was proven to be indigestible and recommended as a soluble dietary fibre.…”

A galactomanana de Prosopis juliflora (PJ) foi obtida por extração em água, a 50 °C, a partir de sementes moídas. As suas características estruturais e as propriedades em solução foram comparadas com as de uma amostra comercial de goma guar (GG). Após degradação parcial, as amostras resultantes foram submetidas à espectroscopia de 13 C RMN. As razões manose/galactose de PJ (M/G = 1,64) e de GG (M/G = 1,85) foram determinadas a partir das áreas relativas aos picos atribuídos a C-1. A expansão das linhas do C-4 revelaram diferenças na estrutura fina das duas galactomananas. A viscosidade intrínseca determinada para a amostra de GG, [η] = 10,3 dL g -1 , foi ligeiramente maior do que a determinada para a PJ, [η] = 9,4 dL g -1 . Experimentos dinâmicos realizados nas mesmas concentrações mostraram comportamentos viscoelásticos similares para as duas gomas. Nenhum aumento no módulo de armazenamento (G′) foi observado para misturas κ-carragenana/PJ em 0,1 mol L -1 KCl em uma concentração total de 1,0 g L -1 , em relação à κ-carragenana sozinha. Géis fortes, obtidos pela mistura de κ-carragenana e PJ ou GG em 0,25 mol L -1 KCl em uma concentração total de 10 g L -1 apresentaram propriedades mecânicas similares.The galactomannan from Prosopis juliflora (PJ galactomannan) was extracted from milled seeds in water at 50 o C. Its structural and solution properties were characterised in comparison with a commercial sample of guar gum (GG galactomannan). After partial degradation, the resulting samples were submitted to 13 C-NMR spectroscopy. The mannose to galactose (M/G) ratios of PJ (M/G = 1.64) and GG (M/G = 1.85) galactomannans were estimated from the relative peak areas of the corresponding C-1 lines. Expansion of the C-4 lines revealed differences in the fine structure of the two galactomannans. The intrinsic viscosity determined for the GG sample, [η] = 10.3 dL g -1 , was slightly higher than that determined for PJ galactomannan, [η] = 9.4 dL g -1 . Dynamic experiments carried out at the same concentrations showed similar viscoelastic behaviours for the two gums. No enhancement in the storage modulus (G′) was observed for κ-carrageenan/PJ mixed solution in 0.1 mol L -1 KCl at 1.0 g L -1 total polymer concentration, in relation to κ-carrageenan alone. Self-supporting gels obtained by mixing κ-carrageenan and PJ or GG galactomannans in 0.25 mol L -1 KCl at 10 g L -1 total polymer concentration displayed similar mechanical properties.
