The objective of this study was to determine the sample size needed to evaluate characters of mature fruits of yellow mombin (Spondias mombin L.). 100 fruits were evaluated from plants grown under a shading system. In the laboratory, these fruits were measured by the characters: longitudinal length (mm);equatorial diameter (mm);fruit mass (g);yield of pulp (%);total soluble solids—TSS (°Brix);titratable acidity—TA (% citric acid) and ratio (TSS/TA), being calculated the measures of central tendency and dispersion, and verified normality. Next, the sample size for each character was determined. For experimental evaluation of cajámirim fruits, considering an accuracy of 10% around the mean, 40 fruits per treatment should be evaluated, considering a completely randomized experiment.

We report the application of a solid lanthanum-ceria-zinc catalyst in the catalytic regeneration of diesel particulate filters （DPF） in diesel engines. We synthesized a CeO2- ZnO-La2O3 （Ce-Zn-La） mixed oxide by a lactic acid-mediated sol-gel method, which efficiently coated cordierite substrates for soot capture and combustion. We studied the effects of La loading on the physicochemical and catalytic properties of Ce-Zn mixed oxide during lowtemperature soot combustion processes. We characterized the synthesized catalysts by X-ray diffraction （XRD）, Fourier-transform infrared spectroscopy （FTIR）, N2 adsorption, Raman spectroscopy, oxygen storage capacity （OSG）, and scanning and transmission electron microscopy （SEM and TEM）. Thermogravimetric and differential thermal analysis （TGA/DTA） confirmed that the catalysts effectively reduced the soot oxidation temperature. The ternary Ce-Zn-La mixed oxide catalyst with Ce/Zn/La atomic ratio of 2：1：0.5 had the highest catalytic activity and promoted soot oxidation at temperatures below 390℃. This indicated that the large number of oxygen vacancies in the catalyst structure generated oxygen species at low temperatures. Raman spectroscopy measurements revealed the presence of oxygen vacancies and lattice defects in Ce-Zn-La samples, which were key parameters concerning the stability and redox properties of the prepared catalysts.

The first version of the Brazilian Oceano- graphic Modeling and Observation Network （REMO） ocean data assimilation system into the Hybrid Coordi- nate Ocean Model （HYCOM）（RODAS H） has recently been constructed for research and operational purposes. The system is based on a multivariate Ensemble Optimal Interpolation （EnOI） scheme and considers the high fre- quency variability of the model error co-variance matrix. The EnOl can assimilate sea surface temperature （SST）, satellite along-track and gridded sea level anomalies （SLA）, and vertical profiles of temperature （T） and salinity （S） from Argo. The first observing system experiment was carried out over the Atlantic Ocean （78°S-50°N, 100°W-20°E） with HYCOM forced with atmospheric reanalysis from 1 January to 30 June 2010. Five integra- tions were performed, including the control run without assimilation. In the other four, different observations were assimilated： SST only （A SST）; Argo T-S profiles only （AArgo）; along-track SLA only （A_SLA）; and all data employed in the previous runs （A_All）. The A_SST, A_Argo, and A_SLA runs were very effective in improv- ing the representation of the assimilated variables, but they had relatively little impact on the variables that were not assimilated. In particular, only the assimilation of S was able to reduce the deviation of S with respect to ob- servations. Overall, the A_All run produced a good analy- sis by reducing the deviation of SST, T, and S with respect to the control run by 39%, 18%, and 30%, respectively, and by increasing the correlation of SLA by 81%.

Primary adenocarcinoma of the small intestine occurs in over 50% of cases in the duodenum. However,its location in the third and fourth duodenal portions occurs rarely and is a diagnostic challenge. The aim of this work is to report an adenocarcinoma of the third and fourth duodenal portions,emphasizing its diagnostic difficulty and the value of video capsule endoscopy. A man,40 years old,with no medical history,with abdominal discomfort and progressive fatigue,presented four months ago with one episode o f m o d e ra t e m e l e n a. T h e p hy s i c a l e x a m i n a t i o n was normal,except for mucosal pallor. Blood tests were consistent with microcytic,hypochromic iron deficiency anemia with 7.8 g/d L hemoglobin. The upper and lower endoscopy were normal. Additional work-up with video capsule endoscopy showed a polypoid lesion involving the third and fourth portions o f t h e d u o d e n u m. B i o p s y s h o w e d a m o d e ra t e l y differentiated adenocarcinoma. Abdominal computed tomography showed a wall thickening from the third duodenal portion to the proximal jejunum,without distant metastasis. The patient underwent segmental resection(distal duodenum and proximal jejunum) with duodenojejunostomy. The surgical specimen histology confirmed the biopsy diagnosis,with transmural infiltration,without nodal involvement. Conclusion: Adenocarcinoma of the third and fourth portions of the duodenum is difficult to diagnose and capsule endoscopy is of great value.

This study aimed to develop and characterize a cake based on a flour mixture of pigeonpea and rice. Four cake formulations of different percentages of pigeonpea flour (PF) and Rice Flour (RF) (0% PF + 100% RF, 10% PF + 90% RF, 20% PF + 80% RF, 30% PF + 70% RF) were developed based on a traditional formulation. Microbiological, physicochemical and sensory evaluations were performed. The tasters preferred the mix formulation containing 30% pigeonpea and 70% rice (p product, with good acceptance and technological potential. This product meets the needs of the food industry, such as: 1) it is gluten-free;2) contributes for the adoption of healthy eating habits;3) promotes family farming;and 4) stimulates the consumption of regional vegetables that can be incorporated into school meals menus, rescuing the consumption habits of rice and beans and eventually valuing the traditional Brazilian diet. It is worth noting the low lipid, high fiber, iron and zinc content characteristic of the developed product.
