2Smart Transformer/Large Flexible Transformer显示文摘Solid-state transformer-based smart transformer(ST)can provide the dc connectivity and advanced services to improve the grid performance and to increase the penetration of the power electronics interfaced resources(e.g.,distributed generators and electric vehicle charging stations)in modern electricity distribution grids.Since the ST is a new and effective paradigm of the electricity grid evolution to well understand the ST,this paper systematically presents the basic architecture and the typical control schemes of the ST and then the advanced services that ST can provide to improve the electricity grids performances in terms of the power flow control,power quality improvement,active damping and active contribution to improve distribution grid resilience by means of enabling autonomous microgrids operation as well as launching a restoration procedure following a general blackout.Rongwu Zhu Markus Andresen Marius Langwasser Marco Liserre Joao Pecas Lopes Carlos Moreira Justino Rodrigues Mario Couto 2020CES Transactions on Electrical Machines and Systems2020,4,4:3

4Mathematical simulation of radial heat transfer in packed beds by pseudohomogeneous modeling显示文摘Uniform flow regime and constant effective thermal conductivity inside packed beds are commonly accepted in the evaluation of the fluid dynamics and heat transfer in such systems.However,several authors have confirmed the presence of an oscillatory velocity profile caused by the effective contribution of porosity profile in the fluid dynamic behavior of packed beds,which directly influences the heat transfer inside the beds.This paper describes the application of a pseudo-homogeneous mathematical model for describing heat transfer in packed beds with oscillatory profiles of velocity and porosity,using a radius-dependent model for effective thermal conductivity k r.Several temperature profiles were obtained in a packed bed system with thermal source located on the wall.The simulated temperature and effective thermal conductivity obtained from simulations were compared with experimental data and calculation from a model based on uniform k r fitting.The results indicate that the proposed mathematical modeling was capable of better representing the heat transfer in the packed bed.Rodrigo Béttega Marcos Flávio Pinto Moreira Ronaldo Guimaraes Corrêa José Teixeira Freire 2011Particuology2011,9,2:2
5Tracheobronchial Polyflex stents for the management of benign refractory hypopharyngeal strictures显示文摘AIM:To describe a modified technique for placement of a tracheobronchial self-expanding plastic stent(SEPS) in patients with benign refractory hypopharyngeal strictures in order to improve dysphagia and allow stricture remodeling.METHODS:A case series of four consecutive patients with complex hypopharyngeal strictures after combinedtherapy for laryngeal cancer,previously submitted to multiple sessions of dilation without lasting improvement,is presented.All patients underwent placement of a small diameter and unflared tracheobronchial SEPS.Main outcome measurements were improvement of dysphagia and avoiding of repeated dilation.RESULTS:The modified introducer system allowed an easy and technically successful deployment of the tracheobronchial Polyflex stent through the stricture.All four patients developed complications related to stent placement.Two patients had stent migration(one proximal and one distal),two patients developed phanryngocutaneous fistulas and all patients with stents in situ for more than 8 wk had hyperplastic tissue growth at the upper end of the stent.Stricture recurrence was observed at 4 wk follow-up after stent removal in all patients CONCLUSION:Although technically feasible,placement of a tracheobronchial SEPS is associated with a high risk of complications.Small diameter stents must be kept in place for longer than 3 mo to allow adequate time for stricture remodeling.Rui Almeida Silva Nuno Mesquita Pedro Pimentel Nunes Elisabete Cardoso Ricardo Marcos Pinto Luís Moreira Dias 2012World Journal of Gastroenterology2012,18,6:2

13Vibrio spp.from Macrobrachium amazonicum prawn farming are inhibited by Moringa oleifera extracts显示文摘Objective:To investigate the in vitro antimicrobial potential of extracts of stem,leaves,flowers,pods and seeds of Moringu okifera(M.okifera) against Vibrio spp.from hatchery water and the prawn Mmrobrachium amazonicum.Methods:The ethanol extracts of stem,leaves,pods and seeds and chloroform extract of flowers of M.oleifera were tested against Vibrio cholerue(V.cholerae) serogroups non-O1/non-O139(n=4).Vibrio vulnificus(n=l) and Vibrio mimicus(n=1).Escherichia coli(E.coli)(ATCC(?) 25922) was used as quality control.Vibrio species were obtained from Macmbrachium amazonicum prawns and from hatchery water from prawn farming.The Minimum Inhibitory Concentration(MIC) was determined by broth microdilution method.Results:The best result was obtained with the ethanol extract of pods,which inhibited three strains of the V.choleme,Vibrio vulnificus,Vibrio minimis and E.coli(MIC range 0.312-5.000 mg/mL).The chloroform extract of flowers was effective against all V.chokrae strains and E.coli(MIC range 0.625-1.250 mg/mL).However,the ethanol extracts of stem and seeds showed low effectiveness in inhibiting the bacterial growth.Conclusions:The extracts of pods,flowers and leaves of M.oleifera have potential for the control of Vibrio spp.Further studies are necessary to isolate the bioaetive compounds responsible for this antimicrobial activity.Raimunda Samia Nogueira Brilhante Jamille Alencar Sales Celia Maria de Souza Sampaio Francisco Geraldo Barbosa Manoel de Araujo Neto Paiva Glaucia Morgana de Melo Guedes Lucas Pereira de Alencar Yago Brito de Ponte Tereza de Jesus Pinheiro Gomes Bandeira Jose Luciano Bezerra Moreira Debora de Souza Collares Maia Castelo-Branco Waldemiro de Aquino Pereira-Neto Rossana de Aguiar Cordeiro Jose Julio Costa Sidrim Marcos Fabio Gadelha Rocha 2015Asian Pacific Journal of Tropical Medicine2015,8,11:1

16Trans-10,cis-12 conjugated linoleic acid reduces neutral lipid content and may affect cryotolerance of in vitro-produced crossbred bovine embryos显示文摘Background:Due to high neutral lipids accumulation in the cytoplasm,in vitro-produced embryos from Bos primigenius indicus and their crosses are more sensitive to chilling and cryopreservation than those from Bos primigenius taurus.The objective of the present study was to evaluate the effects of trans-10,cis-12 conjugated linoleic acid(CLA) on the development and cryotolerance of crossbred Bos primigenius taurus x Bos primigenius indicus embryos produced in vitro,and cultured in the presence of fetal calf serum.Bovine zygotes(n = 1,692)were randomly assigned to one of the following treatment groups:1) Control,zygotes cultured in Charles Rosenkrans 2 amino acid(CR2aa) medium(n = 815) or 2) CLA,zygotes cultured in CR2 aa medium supplemented with 100 μmol/L of trans-10,cis-12 CLA(n =877).Embryo development(cleavage and blastocyst rates evaluated at days 3 and 8 of culture,respectively),lipid content at morula stage(day 5) and blastocyst cryotolerance(re-expansion and hatching rates,evaluated 24 and 72 h post-thawing,respectively) were compared between groups.Additionally,selected mRNA transcripts were measured by Real-Time PCR in blastocyst stage.Results:The CLA treatment had no effect on cleavage and blastocyst rates,or on mRNA levels for genes related to cellular stress and apoptosis.On the other hand,abundance of mRNA for the 1-acylglycerol-3-phosphate0-acyltransferase-encoding gene(AGPAT),which is involved in triglycerides synthesis,and consequently neutral lipid content,were reduced by CLA treatment.A significant increase was observed in the re-expansion rate of embryos cultured with trans-10,cis-12 CLA when compared to control(56.3 vs.34.4%,respectively,P = 0.002).However,this difference was not observed in the hatching rate(16.5 vs.14.0%,respectively,P=0.62).Conclusions:The supplementation with trans-10,ds-12 CLA isomer in culture medium reduced the lipid content of in vitro produced bovine embryos by reducing the gene expression of 1-acylglycerol 3-phosphate 0-acyltransferase(AGPAT) enzyme.However,a possible improvement in embryo cryotolerance in response to CLA,as suggested by increased blastocyst re-expansion rate,was not confirmed by hatching rates.Ribrio Ivan Tavares Pereira Batista Nadia Rezende Barbosa Raposo Paulo Henrique Almeida Campos-Junior Michele Munk Pereira Luiz Sergio Almeida Camargo Bruno Campos Carvalho Marco Antonio Sundfeld Gama Joao Henrique Moreira Viana 2014Journal of Animal Science and Biotechnology2014,5,4:1
