From beginning of 90＇s, the Brazilian nuclear policy has been changed radically. This determined the interruption of most R＆D fuel cycle activities and the facilities shutdown at Nuclear and Energetic Research Institute （IPEN）. The existence of those facilities also implicated in the need of constant surveillance, representing additional obligations, costs and problems. The reasons to promote the dismantling of the IPEN＇s Nuclear Fuel Cycle Pilot Plants elapsed mainly from the need of physical space for new activities, since the R＆D in the nuclear fuel cycle area were interrupted. In the last decade, IPEN has changed its ＂nuclear profile＂ to a ＂comprehensive and multidisciplinary profile＂. With the end of most nuclear fuel cycle activities, the former facilities were distributed in four different centers. Each center has adopted a different strategy and priority to face the D＆D problem. The available resources depend on the specific program in each area＇s development （resources available from other sources, not only from Brazilian National Nuclear Energy Commission （CNEN）. One of those new activities is the IPEN＇s Environmental Program. This paper describes the procedures, problems faced and results related to the reintegration of the former pilot plant areas as new laboratories of the Chemical and Environmental Technology Center-CQMA of the IPEN.

This study investigated the effects of yerba mate consumption, a South American beverage, on cardiac remodeling in rats. For this purpose, 24 male Wistar rats were divided into Control Group (CG) which received filtered water and a standard diet, and Yerba Mate Group (YM), 6 g of Ilex paraguariensis in 100 ml water and the same diet, for 30 days. The YM group showed a reduction in final body weight and food consumption without altering weight gain. Regarding cardiac remodeling, the YM group exhibited a decrease in the right ventricle weight/final body weight ratio, suggesting cardiac atrophy, without affecting the atria and left ventricle. There was no change in cardiomyocyte area or nuclear fractal dimension in both groups. However, animals that consumed yerba mate showed increased collagen deposition and a smaller fractal dimension in the left ventricle. The consumption of yerba mate at room temperature for 30 days induced changes in cardiac remodeling, as evidenced by increased collagen deposition and alterations in fractal dimension in the left ventricle.

Alzheimer's disease is a severe, highly disabling neurodegenerative disease, clinically characterized by a progressive decline in cognitive functions, and is the most common form of dementia in the elderly. For decades, the search for disease-modifying therapies has focused on the two main Alzheimer's disease histopathological hallmarks, seeking to prevent, mitigate, or clear the formation of extracellular aggregates of β-amyloid peptide and intracellular neurofibrillary tangles of tau protein, although without clinical success. Mesenchymal stem cell-based therapy has emerged as a promising alternative for the treatment of Alzheimer's disease, especially because it also targets other crucial players in the pathogenesis of the disease, such as neuroinflammation, synaptic dysfunction/loss, oxidative stress, and impaired neurogenesis. Herein, we review current knowledge of the therapeutic potential of mesenchymal stem cells and their extracellular vesicles for Alzheimer's disease, discussing the most recent findings in both preclinical and clinical trials as well as how advanced technologies have helped to overcome some limitations and contributed to stimulate the development of more effective treatments.

Drying of pasty and granular materials in mechanically and conventional spouted beds

Particuology 2019年第1期17卷 176-183页

A contactor vessel was built to operate as either a mechanically or a conventional spouted bed for the purpose of analyzing the drying of pasty and granular materials under comparable conditions in both configurations. A classical conical–cylindrical spouted bed with a 60° conical base and an air inlet central orifice was modified to enable the switch by introducing in the vessel’s center an open helicoidal conveyor screw placed above the air inlet orifice. This screw is removable and conveniently returns the bed to its conventional spouted configuration. Experiments on drying solutions (calcium carbonate suspensions and skimmed milk) and granular materials (porous alumina particles) were performed for various bed parameter settings. The spouting pressure drop, outlet air temperature, and relative humidity were measured over time under different conditions. Mechanical agitation is proved effective in drying diluted carbonate calcium liquid suspensions and coarse porous alumina particles at an air velocity approximately 50% lower in comparison to drying in a conventional spouted bed. The conventional spouted bed performed better at drying liquid skimmed milk as the mechanical agitation combined with the axial inlet air flow is not effective in mitigating sticking and powder agglomeration in the bed when handling pastes of complex composition. Introducing mechanical agitation in the designed setup broadens the operating range of a conventional spouted bed with axial air flow in the inlet.

Animal Manure as a Nitrogen Source to Grass

引用

American Journal of Plant Sciences 2015年第7期6卷 899-910页

作者： Anderson de Moura Zanine Daniele de jesus ferreira department of Animal Science Federal University of Mato Grosso Rondonópolis Brazil

The use of animal manure has been studied increasingly in recent years due to the excess waste in confinements, which generates great amounts of animal excreta;and as a result of the worsening petroleum crisis, the cost of mineral fertilizing products has increased. Thus, studies point out the potential of this waste to improve biotic and abiotic soil condition and nutritional value of forage. Substances ingested by animals that resist the action of gastric enzymes are enriched with large amounts of bacteria, other microorganisms and other substances to form residual feces, the main component of manure, which, together with the wash water from barnyard urine, form the slurry. The volume of living or dead bacteria in the feces represents 20% of total manure and it is from these that a large amount of nitrogen originates as protein. Due to this potentiality, animal manure can be used as an input in agriculture, impacting positively on production and forage productivity, and having a favorable effect on the environment.

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

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.

Analytical determination of Benzophenone-3 in Sunscreen Preparations Using Boron-Doped Diamond Electrodes

引用

American Journal of Analytical Chemistry 2011年第3期2卷 383-391页

作者： Michelli Thomaz Laranjeira Fabio de Lima Silvio Cesar de Oliveira Valdir Souza ferreira robson Tadeu Soares de Oliveira 不详

A new electroanalytical procedure was developed for the determination of Benzophenone-3 (BENZO) in commercial sunscreen as the active ingredient. The procedure is based on the use of electrochemical methods as cyclic and square-wave voltammetry, with boron-doped diamond (BDD) electrodes. The reduction of BENZO in Britton-Robinson buffer (0.1 mol●L–1) using this type of electrode gives rise to one irreversible peak in –1.30 V (versus Ag/AgCl) in presence of cationic surfactant cetyltrimethylammonium bromide (CTABr). The proposed electrochemical method was successfully applied to the analysis of commercially available pharmaceutical preparations.
