The objective of this study was to evaluate the radiation use efficiency (RUE) and canopy structure of elephant grass varieties (Cenchrus purpureus Schum.) of contrasting statures, under monocropping or intercropped with butterfly pea (Clitoria ternatea L.) in cut-and-carry systems. Two tall varieties (elephant B and IRI-381), and two dwarf ones (Mott and Taiwan A-146 2.37), were evaluated as monocrops or binary intercrops with the legume in a 2-year trial with eight harvests. Greater annual leaf biomass accumulation was observed in the monocrops of the tall variety elephant B (7.76 t/ha per year) and dwarf Mott (8.08 t/ha per year). Greater herbage bulk density (59 kg/ha per cm) and leaf area index (3.83) were recorded in canopies of dwarf Mott than in those composed of IRI-381 (37 kg/ha per cm and 3.48, respectively). In the first year, dwarf varieties Mott and Taiwan A-146 2.37 showed less RUE (0.89 and 0.84 g dry matter (DM)/MJ, respectively) than the elephant B (1.46 g DM/MJ). Higher non-fibre carbohydrate (NFC) contents were found in dwarf Mott under monocrop (180 g/kg) and in the intercrop systems. Tall varieties elephant B and IRI-381 showed greater efficiency in intercepting the radiation to accumulate herbage via stem accumulation. Dwarf Mott variety exhibited short stems and great leaf biomass accumulation that favoured denser canopies with higher content of NFCs in vegetal tissue. Planting butterfly pea into rows of elephant grass varieties can be adopted with no significant losses in RUE caused by light extinction, regardless of the grass stature.

The objective of this study was to describe and explain the effect of adding corn meal (CM) on losses, fermentation characteristics and nutritional value of silages from two elephant grass [Cenchrus purpureus (Schumach.) Morrone] genotypes (Taiwan A-146 2.37 and IRI-381) mixed with butterfly pea (Clitoria ternatea L.) legume. The forage was harvested at 75 days of regrowth from elephant grass plots intercropped with butterfly pea legume and ensiled with or without CM at 5% of dry matter (DM) content. Greater gas losses (12 g/kg) and pH (4.2) were observed in the Taiwan A-146 2.37 + butterfly pea silages. The greatest crude protein content was observed in the ‘Taiwan A-146 2.37’ + butterfly pea silage added with CM (116 g/kg). Silages with additive and those containing IRI-381 had a greater acid detergent fibre content (367 and 366 g/kg, respectively). CM increased the silage DM (221 g/kg), remaining water-soluble carbohydrates contents (26 g/kg) and in vitro digestibility of DM. The aerobic stability was maintained until 45 h after opening the silos. All silages presented a good fermentative profile and were not affected by the relatively large proportion of butterfly pea (>34%) in the ensiled mass as indicated by the reduced contents of butyric acid and ammonia nitrogen. CM reduces total losses, increases DM recovery and improves the nutritional value of silages from mixed elephant grass–butterfly pea legume.

Introduction
Elderly institutionalization involves an emotional adaptation and the research shows that the risk of depression increases.
ObjectivesEvaluate the impact of a neuropsychological group rehabilitation program (NGRP) on depressive symptomatology of institutionalized elderly.
AimsNGRP influences the decrease of depressive symptoms.
MethodsElderly were assessed pre- and post-intervention with the Geriatric Depression Scale (GDS) and divided into a Rehabilitated Group (RG), a Waiting List Group (WLG), and a Neutral Task Group (NTG).
ResultsIn this randomized study, before rehabilitation, 60 elderly people (RG; 80.31 ± 8.98 years of age; 74.2% women) had a mean GDS score of 13.33 (SD = 9.21). Five elderly included in the NTG (80.13 ± 10.84 years; 75.0% women) had a mean GDS score of 10.60 (SD = 4.72). Finally, 29 elderly in the WLG (81.32 ± 6.68 years; 69.0% women) had a mean GDS score of 14.93 (SD = 6.02). The groups were not different in GDS baseline scores (F = 0.74; P = 0.478). ANCOVA has shown significant differences (P < 0.05) in GDS scores between the three groups after 10 weeks. Sidak adjustment for multiple comparisons revealed that elderly in the WLG got worse scores in GDS, comparing with elderly in RG (P < 0.01), and with elderly in NTG (P < 0.05).
ConclusionsElderly that are not involved in a task get worse in depressive symptomatology. Being involved in a structured group task means lower depressive symptoms and being in a NGRP means even greater results.

The BW has been largely used as a selection criterion in genetic selection programmes; however, increases in BW can affect animal metabolism and metabolites. The knowledge of how genetic potential for growth affects the metabolites can give a footprint of growth metabolism. This research aimed to evaluate the effect of genetic potential for post-weaning growth (GG) on performance, carcass traits and serum metabolome of non-castrated Nellore males during the finishing phase. Forty-eight Nellore non-castrated males, with divergent potential for post-weaning growth, were selected and divided into two groups: high potential for post-weaning growth (HG; n = 24) and low potential for post-weaning growth (LG; n = 24). Animals were kept and fed for 90 days where performance and ultrasound carcass traits were evaluated. Blood samples were collected at the beginning and end of feeding period to analyse serum metabolites concentration. The hot carcass weight and dressing percentage were recorded at slaughter. The feedlot performance and carcass traits were not affected by genetic potential. The HG animals had a lower glucose (P = 0.039), glutamate (P = 0.038), glutamine (P = 0.004), greater betaine (P = 0.039) and pyruvate (P = 0.039) compared to the LG group at the beginning of feedlot. In addition, higher creatine phosphate concentrations were observed at the beginning of feeding period, compared to final, for both groups (P = 0.039). In conclusion, the genetic potential for post-weaning growth does not affect performance and carcass traits during the finishing period. Differences in metabolite concentrations can be better found at the beginning of feedlot, providing a footprint of growth metabolism, but similar metabolite concentration at the end of finishing period.

The mineralogy of the silt fraction of a 1.5 m-deep, well developed, intensely weathered, greyish soil profile from a toposequence on a tableland covered by agricultural crops in the upper valley of the Jequitinhonha river basin, Minas Gerais, Brazil, has been studied by X-ray powder diffraction, 57Fe Mössbauer spectroscopy at 298 K and 80 K, and vibrating sample magnetometry. Mössbauer data collected at room temperature indicated about 17 atom% of the iron content of the sample to be structural Fe2+ in phyllosilicates, which X-ray diffraction showed to be mainly halloysite and kaolinite. The magnetization curve also indicates the presence of a ferrimagnetic phase, tentatively identified by Mössbauer spectroscopy as maghemite (γ-Fe2O3).
These findings support a pedogenetic model for this soil profile, by which the remaining Fe2+ bearing minerals were first formed under relatively anoxic palaeo-conditions of an intense hydric regime. Subsequent drier local conditions, due to a much improved drainage, favoured intensive weathering, leading to the presently developed Oxisol. Even under the more oxidative conditions, part of the Fe2+ -containing phyllosilicates still remained in the profile, which is believed to impart the rather unusual greyish colour (Munsell 10YR 3/2) to this deep tropical soil.

The present study investigated the impact of a western diet during gestation and lactation on the anthropometry, serum biochemical, blood pressure and cardiovascular autonomic control on the offspring. Male Wistar rats were divided into two groups according to their mother’s diet received: control group (C: 18% calories of lipids) and westernized group (W: 32% calories of lipids). After weaning both groups received standard diet. On the 60th day of life, blood samples were collected for the analysis of fasting glucose and lipidogram. Cardiovascular parameters were measured on the same period. Autonomic nervous system modulation was evaluated by spectrum analysis of heart rate (HR) and systolic arterial pressure (SAP). The W increased glycemia (123±2 v. 155±2 mg/dl), low-density lipoprotein (15±1 v. 31±2 mg/dl), triglycerides (49±1 v. 85±2 mg/dl), total cholesterol (75±2 v. 86±2 mg/dl), and decreased high-density lipoprotein (50±4 v. 38±3 mg/dl), as well as increased body mass (209±4 v. 229±6 g) than C. Furthermore, the W showed higher SAP (130±4 v. 157±2 mmHg), HR (357±10 v. 428±14 bpm), sympathetic modulation to vessels (2.3±0.56 v. 6±0.84 mmHg2) and LF/HF ratio (0.15±0.01 v. 0.7±0.2) than C. These findings suggest that a western diet during pregnancy and lactation leads to overweight associated with autonomic misbalance and hypertension in adulthood.

The aim of this study was analyzed if the flour or flaxseed oil treatment contributes to body composition in male rats subjected to early weaning. Pups were weaned for separation from mother at 14 (early weaning, EW) and 21 days (control, C). At 21 days, part of the pups was evaluated (C21 v. EW21). After 21 days, control (C60) was fed with control diet. EW was divided in control (EWC60); flaxseed flour (EWFF60); flaxseed oil (EWFO60) diets until 60 days. Body mass, length and body composition by dual-energy X-ray absorptiometry were determined. EW21 (v. C21) and EWC60 (v. C60 and EWFF60) showed lower (P<0.05) mass, length and body composition. EWFO60 (v. C60 and EWFF60) showed lower (P<0.05) body mass and length, body and trunk lean mass, bone mineral density and content and bone area. Flaxseed flour, in comparison with flaxseed oil, contributes to recovery of body composition after early weaning.

The precocious interruption of lactation is a prime factor for developmental plasticity. Here we analyzed whether flour or flaxseed oil treatment contributes to body and brain mass in male rats subjected to early weaning. Pups were weaned for separation from their mother at 14 (early weaning, EW) and 21 days (control, C). At 21 days, some of the pups were evaluated (C21 v. EW21). After 21 days, control pups (C60) were fed a control diet. EW pups were divided into those fed a control diet (EWC60), those given flaxseed flour (EWFF60), and those given flaxseed oil (EWFO60) until 60 days. EW21 showed lower body and absolute brain mass and higher relative brain mass. At 60 days, EWC60 and EWFO60 had lower body mass. With regard to relative brain mass, EWC60 was heavier; EWFO60 had lower values compared with EWC60 and higher values compared with C60 and EWFF60. These results indicated that flaxseed flour, in comparison with flaxseed oil, contributes to brain development after EW.

We describe the preliminary design of a magnetograph and visible-light imager instrument to study the solar dynamo processes through observations of the solar surface magnetic field distribution. The instrument will provide measurements of the vector magnetic field and of the line-of-sight velocity in the solar photosphere. As the magnetic field anchored at the solar surface produces most of the structures and energetic events in the upper solar atmosphere and significantly influences the heliosphere, the development of this instrument plays an important role in reaching the scientific goals of The Atmospheric and Space Science Coordination (CEA) at the Brazilian National Institute for Space Research (INPE). In particular, the CEA's space weather program will benefit most from the development of this technology. We expect that this project will be the starting point to establish a strong research program on Solar Physics in Brazil. Our main aim is acquiring progressively the know-how to build state-of-the-art solar vector magnetograph and visible-light imagers for space-based platforms to contribute to the efforts of the solar-terrestrial physics community to address the main unanswered questions on how our nearby Star works.

First 405 GHz and 212 GHz solar flare observations were obtained during short campaigns while the new solar submillimeter-wave telescope (SST) was still undergoing adjustments at the CASLEO El Leoncito observatory in the Argentina Andes. We show here preliminary results for a large X1.1 class X-ray event occurred on 2000 March 22, which exhibited a small submm-w continuum response to the slow (minutes) bulk flare emission, and numerous subsecond spikes (100-300 ms), the brightest spikes reaching about 180 and 50 s.f.u. at 405 and 212 GHz, respectively.
