121世纪心电图在临床与科研中的作用显示文摘心电学是心脏病学的一个分支,其主要研究心脏的电活动。经典的12导联心电图通过体表12个位置的探查电极记录心脏的电活动。心电图机是记录心电活动的装置,内置的生物电放大器可以放大各种生物电信号,电流计根据心肌的除极、复极事件进行相应的移动从而描记出心电图.张莉 André s Ricardo Pé rez Riera Peter R. Kowey 刘元伟(译) 2008临床心电学杂志2008,17,6:5
2Challenges and opportunities for nanomaterials in spectral splitting for high-performance hybrid solar photovoltaic-thermal applications:A review显示文摘Hybrid photovoltaic-thermal(PV-T)collectors,which are capable of cogenerating useful thermal energy and electricity from the same aperture area,have a significantly higher overall efficiency and ability to displace emissions compared to independent,separate photovoltaic panels,solar thermal collectors or combinations thereof.Spectral splitting has emerged as a promising route towards next-generation high-performance PV-T collectors,and nanotechnology plays an important role in meeting the optical and thermal requirements of advanced spectral splitting PV-T collector designs.This paper presents a comprehensive review of spectral splitting technologies based on nanomaterials for PV-T applications.Emerging nanomaterials(nanofluids,nanofilms and nanowires)suitable for achieving spectral splitting based on reflection,diffraction,refraction and/or absorption approaches in PV-T collectors are presented,along with the associated challenges and opportunities of these design approaches.The requirements from such materials in terms of optical properties,thermal properties,stability and cost are discussed with the aim of guiding future research and innovation,and developing this technology towards practical application.Nanofluids and nanofilms are currently the most common nanomaterials used for spectral splitting,with significant progress made in recent years in the development of these materials.Nevertheless,there still remains a considerable gap between the optical properties of currently-available filters and the desired properties of ideal filters.Aiming to instruct and guide the future development of filter materials,a simple generalized method is further proposed in this paper to identify optimal filters and efficiency limits of spectral splitting PV-T systems for different scenarios.It is found that the optimal filter of a spectral splitting PV-T system is highly sensitive to the value of thermal energy relative to that of electricity,which therefore depends strongly on the application and location.The efficiency limit of spectral splitting PV-T collectors is significantly higher than that of standalone PV panels.The stability of nanomaterial filters remains a critical challenge for their long-term employment and also for high-temperature operation in practical applications.Gan Huang Sara Riera Curt Kai Wang Christos N.Markides 2020Nano Materials Science2020,2,3:3
3Potential Use of a Poultry Manure Digestate as a Biofertiliser:Evaluation of Soil Properties and Lactuca sativa Growth显示文摘Anaerobic digestion is a process that is widely used for the treatment of organic wastes. The digestate can be used as a soil amendment or crop fertiliser. The aims of our work were to evaluate 1) the physicochemical composition and pathogen content in a digestate from poultry manure, according to international regulations, and 2) the effect of its soil application on the major chemical and biological soil properties and on the growth of Lactuca sativa. The experiment consisted of two groups of pots(with and without crop). Treatments applied to each group were as follows: low and high doses of digestate and inorganic fertiliser, and no application(control)(low dose: 70 kg nitrogen(N) ha^(-1) and 21 kg phosphorus(P) ha^(-1); high dose: 210 kg N ha^(-1) and 63 kg P ha^(-1)). Soil samples were taken 7 and 34 d(harvest) after treatment applications. Heavy metal and pathogen contents in the digestate were below the upper limit values. Despite the high pH and electrical conductivity values of the digestate, both soil parameters presented acceptable values for crop growth. Although there were no initial increases in total inorganic N and available P in soil with digestate application, an increase in the fresh weight of crop was observed with the high dose application. This is probably associated with the slow nutrient release from the digestate during the development of the crop. Changes in the microbial community were temporary and occurred at the initial sampling stage of the experiment.Natalia MóRTOLA Romina ROMANIUK Vanina COSENTINO Maximiliano EIZA Patricia CARFAGNO Pedro RIZZO Patricia BRES Nicolás RIERA Marcos ROBA Mariano BUTTI Daiana SAINZ Lucrecia BRUTTI 2019Pedosphere2019,29,1:2

6在经历 transcatheter 的病人的 atrial 纤维性颤动的临床、预示的含意大动脉的阀门培植显示文摘 AIM: To study a cohort of consecutive patients under-going transcatheter aortic valve implantation (TAVI) and compare the outcomes of atrial fibrillation (AF) patients vs patients in sinus rhythm (SR). METHODS: All consecutive patients undergoing TAVI in our hospital were included. The AF group comprised patients in AF at the time of TAVI or with history of AF, and were compared with the SR group. Procedural, echocardiographic and follow-up variables were compared. Likewise, the CHA 2 DS 2-VASC stroke risk score and HAS-BLED bleeding risk score and antithrombotic treatment at discharge in AF patients were compared with that in SR patients. RESULTS: From a total of 34 patients undergoing TAVI, 17 (50%) were allocated to the AF group, of whom 15 (88%) were under chronic oral anticoagulation. Patients in the AF group were similar to those in the SR group except for a trend (P = 0.07) for a higher logistic EuroSCORE (28% vs 19%), and a higher prevalence of hypertension (82% vs 53%) and chronic renal failure (17% vs 0%). Risk of both stroke and bleeding was high in the AF group (mean CHA 2 DS 2-VASC 4.3, mean HAS-BLED 2.9). In the AF group, treatment at discharge included chronic oral anticoagulation in all except one case, and in association with an antiplatelet drug in 57% of patients. During a mean follow-up of 11 mo (maximum 32), there were only two strokes, none of them during the peri-procedural period: one in the AF group at 30 mo and one in the SR group at 3 mo. There were no statistical differences in procedural success, and clinical outcome (survival at 1 year 81% vs 74% in AF and SR groups, respectively, P = NS). CONCLUSION: Patients in AF undergoing TAVI show a trend to a higher surgical risk. However, in our cohort, patients in AF did not have a higher stroke rate compared to the SR group, and the prognosis was similar in both groups.Pablo Salinas Raúl Moreno Luis Calvo Santiago Jiménez-Valero Guillermo Galeote Angel Sánchez-Recalde Teresa López-Fernández Sergio Garcia-Blas Diego Iglesias Luis Riera Isidro Moreno-Gómez Jose María Mesa Ignacio Plaza Rocio Ayala Rosa Gonzalez José-Luis López-Sendón 2012World Journal of Cardiology2012,4,1:2
