CdCO3 thin films had grown onto glass by chemical bath deposition (CBD), the temperature of the bath (Td) was at 20 °C. The samples were thermal annealed temperature (TAT) in air atmosphere at normal pressure for 2 h at different temperatures in the range of 300-400 °C, in order to perform the crystalline phase transformation from CdCO3→CdO, Scanning Electron microscopy (SEm), X-ray diffraction (XRD) and optical absorption (OA) measurements were carried out to characterized the films. The proportion of constitutive elements measured by means SEm for CdCO3 as-grown were: Cd = 12.8, C = 20.0, O = 67.2; TAT (CdCO3) = 400 °C: Cd = 49.8, O = 50.2, this results indicates good stoichiometric of samples. Patterns XRD show the layer with CdCO3 which has rhombohedral crystallineas-grown peaks at: 2θ = [23.4, 30.2, 36.4, 40.1, 43.8, 48.0, 49.5, 49.9, 58.2, 61.7, 62.9 and 65.5]. TAT (CdCO3) = 400 °C completely disappeared and only peaks of CdO are identified. All of the peaks in this pattern has pure cubic phase of CdO (2θ= [33.1, 38.2, 55.3, 59.9 and 69.3]). The average grain size (GS) which was calculated from the main XRD peak by CdCO3 reduce of 34.5 nm reaching 20 nm respectively was calculated by employing Scherer"s formula. The optical absorption spectra allowed to calculate the values of forbidden bandgap energy (Eg), and hence, the evolution of Eg in the thermally spectra also showed the complete microstructural transformation from as-grown for samples with higher annealing. The critical point of CdCO3→CdO is proposed to occur at TAT = 400 °C, CdCO3 as-grown: Eg = 3.87 eV, TAT (CdCO3) = 400 °C (CdO): Eg = 2.31 eV.

中华神经外科疾病研究杂志 2014年第4期13卷 372-372页

作者： Lorente L martín mm Abreu-González P Ramos L Argueso m Cáceres JJ Solé-Violán J Lorenzo Jm molina I Jiménez A. Hospital Universitario de Canarias Intensive Care

There is a hyperoxidative state in patients with trauma brain injury( TBI). malondialdehyde( mDA) is an end-product formed during oxidative stress,concretely lipid peroxidation. In small studies( highest sample size 50 patients),higher levels of mDA have been found in non-surviving than surviving TBI patients. However,an association between serum mDA levels and mortality in patients with TBI has not been reported. Thus,the objective of this prospective,observational,multicenter study,carried out in six Spanish Intensive Care Units,was to determine whether mDA serum levels are associated with early mortality in a large series of patients with severe TBI. Serum mDA levels were measured in 100 patients with severe TBI on day 1 and in 75 healthy controls. The end-point of the study was 30-day *** found higher serum mDA levels in patients with severe TBI than in healthy controls( P m mDA levels( P m mDA levels were associated with 30-day mortality( OR = 4. 662; 95% CI = 1. 466- 14. 824; P = 0. 01),controlling for Glasgow coma score,age and computed tomography findings. Survival analysis showed that patients with serum mDA levels higher than 1. 96 nmol /mL presented increased 30-day mortality than patients with lower levels( Hazard ratio =3. 5; 95% CI =1. 43-8. 47; P most relevant new finding of our study,the largest to date on serum mDA levels in patients with severe TBI,was an association between serum mDA levels and early mortality.

Ronco” (CINDECA) CCT CONICET-La Plata Universidad Nacional de La Plata Comisión de Investigaciones Científicas La Plata Argentina

The catalytic hydrogenation of D-glucose over a 3 wt% Ru/C catalyst was studied varying the operating conditions in mild conditions range to optimize the obtention of D-sorbitol. The stirring speed, temperature, pressure, and initial glucose concentration were varied between 250 - 700 rpm, 343 - 383 K, 0.5 - 2 mPa, and 0.033 - 0.133 m, respectively. To verify the absence of mass transport limitations, the diffusion of reagents in the gas-liquid interface, the liquid-solid interface, and the internal diffusion in the particles were evaluated. Under the operating conditions studied, the reaction rate showed an order with respect to H2 of 0.586 and with respect to glucose of 0.406. The kinetic data were adjusted using 3 general models and 19 different sub-models based on Langmuir-Hinshelwood-Hougen-Watson (LHHW) kinetics. model 3a was the best one interpreting the aqueous phase hydrogenation of glucose (both reagents competitively adsorbed on the catalyst). The H2 adsorption is dissociative and the rate-limiting step is the surface chemical reaction.

Introduction: Ultraviolet radiation can be harmful to the skin and can create serious problems when a protective substance or equipment is not used regularly, for this reason the present study set out to evaluate the photoprotective effect of the hydroalcoholic extracts of the integument of the red and black varieties of pop beans (m>Phaseolus vulgarism>). materials and method: The extracts were obtained by macerating the tegument of the two varieties of pop beans, black and red, in an ethanol/water (80:20) solution. The thin-layer chromatographic method was used to observe anti-tyrosinase activity, using the 0.05% kojic acid standard as a positive control. The photoprotective effect was evaluated in female mice of seven-week-old, mus m>musculus m>Balb/c, with shaved back and exposed to UV-C radiation for 30 minutes once a day for thirty days to induce photo-damage in the skin. The treatments consisted in the application of extracts at 2% and 5% W/V in gel on the shaved area. Only the gel formulation, sunscreen or no treatment at all was used for the control group. Acute photodamage was quantified using the Draize scale, measuring the degree of erythema and edema;and the degree of photoaging using the Glogau scale at 7 days and 30 days. Results: It was found that the ethanolic extracts of the integument of both varieties of m>Phaseolus vulgarism>, red and black, are practically non-toxic in mice by oral and dermal routes at a limit dose of 5000 mg/kg. The anti-tyrosinase effect at a qualitative level, evaluated by thin layer chromatography, showed the black variety were more active than the red one and both can be compared to the activity of the kojic acid. The two extracts of the two varieties showed photoprotective effect, however the extracts in 5% gel to a greater degree. Conclusions: It was concluded that the hydroalcoholic extract of the pop black beans tegument at 5% in gel has

The increasing use of petrodiesel-biodiesel fuel blends throughout the world requires fast, economic and efficient analytical techniques that can be used for the quality control of these fuels. In this work, we developed an analytical method for determining the concentration of African palm biodiesel in blends with petrodiesel;the method is based on infrared spectroscopy (FTIR-ATR). To build a prediction model, nineteen petrodiesel-biodiesel blends were prepared in triplicate with biodiesel concentrations for 0%-100% by weight. The blends were analyzed using Fourier transform infrared spectroscopy, the spectral fingerprint data were used to build a prediction model through PLS regression. The optimal number of principal components (PCs), the standard error of calibration (SEC), the standard validation error (SEV), the correlation coefficient of calibration (r Cal) and the validation correlation coefficient (r Val) were used to validate the predictive ability of the model. The results show that the model obtained in this work has a good ability for determining the concentration of African palm biodiesel in petrodiesel-biodiesel blends.
