The objective of this work was to evaluate the effect of different water deficiency and rehydration levels on the concentrations of osmoregulators in two plant species（Hymenaea courbaril and H. Stigonocarpa） in the Amazon. We adopted a 2×5×5 factorial system,referring to 2 species（H. courbaril and H. stigonocarpa）and 5 stages of hydration and rehydration. The five hydration and rehydration stages were established in:（1）Control treatment E0;（2） Plants with 13 days of stress after incubation—E13;（3） Plants with 26 days of stress E26;（4）The plants that were established after 26 days after incubation and rehydrated for two days（RD2）;（5） rehydrated for two days（RD4）. The plants that were established after 26 days after incubation and rehydrated for four days. The experiment totaled fifty young plants with five *** measurements were performed at the beginning of the experiment（E0） at 13（E13） and 26（E26） days after the water stress, in which the plants were rehydrated,repeating the analyses after two（RD2） and four（RD4）days. Both species increased the sucrose concentration by18%, with a decrease of 52% in starch content. The RD4 time presented the highest mean starch concentration(0.19 mmol g-1 of the residue for H. courbaril and0.27 mmol g;of residue for H. stigonocarpa). Increased proline concentrations were recorded for controls until RD2 for both species. For glycine betaine, the highest increases in treatments E26 and RD2 were observed for the H. courbaril species. Our rehydration period was not sufficient for total recovery of pre-stress concentrations of all studied solutes.

The REMO Ocean Data Assimilation System into HYCOM(RODAS_H):General description and Preliminary Results

作者： Clemente Augusto souza TANAJURA Alex Novaes SANTANA Davi MIGNAC leonardo Nascimento LIMA Konstantin BELYAEV XIE Ji-Ping Physics Institute Federal University of Bahia (UFBA) Salvador 40170-280 Brazil Oceanographic Modeling and Observation Network (REMO) Center for Research in Geophysics and Geology Federal University of Bahia (UFBA) Salvador 40170-280 Brazil Ocean Sciences department University of California Santa Cruz (UCSC) USA Graduate Program in Geophysics Federal University of Bahia (UFBA) Salvador Brazil Shirshov Institute of Oceanology Russian Academy of Sciences (SHIRSHOV/RAS) Moscow Russia Institute of Atmospheric Physics(IAP) Chinese Academy of Sciences (CAS)

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%.

Neuroplasticity in Spinal Trauma: A Current Narrative Review of Treatments

引用

World Journal of Neuroscience 2021年第2期11卷 91-107页

作者： Vinicius Benatti Freire Lucas Cressoni de souza Mario Henrique de Lima Martinelli leonardo Moysés Sacchi Thales Andolfo de souza Antonio Eduardo Damin Medical Students of the Nove de Julho University (Campus Vergueiro) S&#227o Paulo Brazil department of Neurology of the Nove de Julho University Medical School Neurologist and Professor of Neurology at Nove de Julho University Medical School S&#227o Paulo Brazil

Neuroplasticity is a condition that is present from birth, being found in the central and peripheral nervous system, in both physiological and pathological terms. Based on the findings, therapeutic and non-therapeutic attempts were tested on spinal cord trauma to recover locomotor function below the level of the injury. The work defined and showed other forms of the term neuroplasticity, talk about some pathological and non-pathological conditions, and, finally, show neuroplasticity and some of its treatments in the spinal cord injury process. A narrative literature review from 2000 to 2020 of the PubMed platform was conducted and analysis of two books for the elaboration of this work. Animal/human studies were included that addressed pathologies, forms of treatment for spinal trauma, and qualis from B1 to A1. Pre-2000 articles, which addressed neuroplasticity only to understand the molecular mechanisms and articles that were not in English, were excluded. As a result, the main molecules and structures that inhibit neuroplasticity were found, and, based on their knowledge, forms of treatments were developed to inhibit these molecules and structures to assist in neuroplasticity and assist in possible functional recovery. It can be concluded that the physiological barriers are already being overcome by the most recent forms of treatment and that soon new studies may propose a form of treatment that is protocoled for all patients.

Automatic Stamping Charger---Stamping of Blended Coal-Theorical Study and Practice Analysis at TKCSA

引用

Journal of Mechanics Engineering and Automation 2015年第10期5卷 573-579页

作者： Yan Samuel Ferreira Junqueira leonardo de souza Pinto Robson Coelho Jose Maria Clemente Technical Unit Iron Making ThyssenKrupp CSA Rio de Janeiro 23560-352 Brazil Coke Plant Maintenance department ThyssenKrupp CSA Rio de Janeiro 23560-352 Brazil Independent Consult Vitoria Brazil

The coke plant of a steel plant corresponds to the area that transforms a blend of coal into coke for using in blast furnace and steam to power plant. The coking plant of ThyssenKrupp CSA uses the heat recovery technology with stamping charger for stamping and preparation a blend of coals for charging and coking. Stamping technology adds several benefits to the process, such as increased density, homogeneity and alignment of the coal cake charged into the oven, as well as provides better control of the coking process, improves parameters of coke quality and allows coal blending with lower coking power, thereby reducing the production cost of coke and power generation. Through the automation of stamping charger, it is possible to evaluate and calculate the stamped coal density charged and the productivity gains this system provides.
