| 1 | Reaction kinetics modeling for lithium and cobalt recovery from spent lithium-ion batteries using acetic acid显示文摘Lithium and cobalt recovery from spent lithium-ion batteries(LIBs) is a major focus because of their increased production and usage. The conventional method for recycling spent LIBs using inorganic acids produces harmful byproducts. In this work, the leaching agent was substituted with a less expensive and more environmentally friendly alternative—acetic acid—and a mathematical model was developed to describe the kinetics of the recovery process. The variables used were the pH value, temperature, H_2O_2 concentration, and the solid-to-liquid(S/L) ratio. The mathematical model used was the shrinking core model, which was modified to accommodate an equilibrium reaction. The experimental results show that the rate of recovery of Li and Co over time was only affected by temperature. The leaching behaviors of Li and Co were found to oppose each other. An increase in temperature resulted in increased recovery of Li but decreased recovery of Co because of the product-favoring endothermic reaction of Li and the reactant-favoring exothermic reaction of Co. The product of Li has a lower entropy value than the reactant as a free-moving ion, whereas the product of Co leaching has a higher entropy value as a stiff crystal complex. Thus, temperature conditioning is a pivotal factor in the leaching of spent LIBs. | Hendrik Setiawan Himawan Tri Bayu Murti Petrus Indra Perdana | 2019 | International Journal of Minerals,Metallurgy and Materials2019,26,1: | 9 |
| 2 | Classification of Soil Types Using Geographic Object-Based Image Analysis and Random Forests显示文摘There is increasing interest in developing automatic procedures to segment landscapes into soil spatial entities that replace conventional, expensive manual procedures for delineating and classifying soils. Geographic object-based image analysis(GEOBIA)partitions remote sensing imagery or digital elevation models into homogeneous image objects based on image segmentation. We used an object-based methodology for the detailed delineation and classification of soil types using digital maps of topography and vegetation as soil covariates, based on the Random Forests(RF) classifier. We compared the object-based method's results with those of a pixel-based classification using the same classifier. We used 18 digital elevation model derivatives and 5 remote sensing indices that were related to vegetation cover and soil. Using 171 soil profiles with their associated environmental variable values,the RF method was used to identify the most important soil type predictors for use in the segmentation process. A stack of rastergeodatasets corresponding to the selected predictors was segmented using a multi-resolution segmentation algorithm, which resulted in homogeneous objects related to soil types. These objects were further classified as soil types using the same method, RF. We also conducted a pixel-based classification using the same classifier and soil profiles, and the resulting maps were assessed in terms of their accuracy using 30% of the soil profiles for validation. We found that GEOBIA was an effective method for soil type mapping, and was superior to the pixel-based approach. The optimized object-based soil map had an overall accuracy of 58%, which was 10% higher than that of the optimized pixel-based map. | Andrei DORNIK Lucian DRAGUT Petru URDEA | 2018 | Pedosphere2018,28,6: | 4 |
| 3 | High-energy hybrid femtosecond laser system demonstrating 2×10 PW capability显示文摘We report on a two-arm hybrid high-power laser system(HPLS)able to deliver 2×10 PW femtosecond pulses,developed at the Bucharest-Magurele Extreme Light Infrastructure Nuclear Physics(ELI-NP)Facility.A hybrid frontend(FE)based on a Ti:sapphire chirped pulse amplifier and a picosecond optical parametric chirped pulse amplifier based on beta barium borate(BBO)crystals,with a cross-polarized wave(XPW)filter in between,has been developed.It delivers 10 mJ laser pulses,at 10 Hz repetition rate,with more than 70 nm spectral bandwidth and high-intensity contrast,in the range of 1013:1.The high-energy Ti:sapphire amplifier stages of both arms were seeded from this common FE.The final high-energy amplifier,equipped with a 200 mm diameter Ti:sapphire crystal,has been pumped by six 100 J nanosecond frequency doubled Nd:glass lasers,at 1 pulse/min repetition rate.More than 300 J output pulse energy has been obtained by pumping with only 80%of the whole 600 J available pump energy.The compressor has a transmission efficiency of 74%and an output pulse duration of 22.7 fs was measured,thus demonstrating that the dual-arm HPLS has the capacity to generate 10 PW peak power femtosecond pulses.The reported results represent the cornerstone of the ELI-NP 2×10 PW femtosecond laser facility,devoted to fundamental and applied nuclear physics research. | François Lureau Guillaume Matras Olivier Chalus Christophe Derycke Thomas Morbieu Christophe Radier Olivier Casagrande Sébastien Laux Sandrine Ricaud Gilles Rey Alain Pellegrina Caroline Richard Laurent Boudjemaa Christophe Simon-Boisson Andrei Baleanu Romeo Banici Andrei Gradinariu Constantin Caldararu Bertrand De Boisdeffre Petru Ghenuche Andrei Naziru Georgios Kolliopoulos Liviu Neagu Razvan Dabu Ioan Dancus Daniel Ursescu | 2020 | High Power Laser Science and Engineering2020,8,4: | 4 |
| 4 | Transit time ultrasound perivascular flow probe technology is superior to MR imaging on hepatic blood flow measurement in a porcine model显示文摘Background: The hepatic hemodynamics is an essential parameter in surgical planning as well as in various disease processes. The transit time ultrasound(TTUS) perivascular flow probe technology is widely used in clinical practice to evaluate the hepatic inflow, yet invasive. The phase-contrast-MRI(PC-MRI) is not invasive and potentially applicable in assessing the hepatic blood flow. In the present study, we compared the hepatic inflow rates using the PC-MRI and the TTUS probe, and evaluated their predictive value of post-hepatectomy adverse events. Methods: Eighteen large white pigs were anaesthetized for PC-MRI and approximately 75% hepatic resection was performed under a unified protocol. The blood flow was measured in the hepatic artery(Qha), the portal vein(Qpv), and the aorta above the celiac trunk(Qca) using PC-MRI, and was compared to the TTUS probe. The Bland-Altman method was conducted and a partial least squares regression(PLS) model was implemented. Results: The mean Qpv measured in PC-MRI was 0.55 ± 0.12 L/min, and in the TTUS probe was 0.74 ± 0.17 L/min. Qca was 1.40 ± 0.47 L/min in the PC-MRI and 2.00 ± 0.60 L/min in the TTUS probe. Qha was 0.17 ± 0.10 L/min in the PC-MRI, and 0.13 ± 0.06 L/min in the TTUS probe. The Bland-Altman method revealed that the estimated bias of Qca in the PC-MRI was 32%(95% CI:-49% to 15%); Qha 17%(95% CI:-15% to 51%); and Qpv 40%(95% CI:-62% to 18%). The TTUS probe had a higher weight in predicting adverse outcomes after 75% resection compared to the PC-MRI( β= 0.35 and 0.43 vs β = 0.22 and 0.07, for tissue changes and premature death, respectively). Conclusions: There is a tendency of the PC-MRI to underestimate the flow measured by the TTUS probes. The TTUS probe measures are more predictive of relevant post-hepatectomy outcomes. | Mohamed Bekheit Chloe Audebert Petru Bucur Hans Adriaensen Emilie Bled Mylène Wartenberg Irene Vignon-Clementel Eric Vibert | 2018 | Hepatobiliary & Pancreatic Diseases International2018,17,6: | 3 |
| 5 | Intra-abdominal esophageal duplication cyst: A case report and review of the literature显示文摘Intra-abdominal esophageal duplications are rare en-tities in adults. They are mostly asymptomatic, but since they can lead to complications surgical excision is advised for all duplication cysts. We present a case of a 20-year-old male with colic-like abdominal pain, mimicking symptoms of cholecystolithiasis. However after cholecystectomy the symptoms were still present. A computed tomography-scan of the abdomen and an endoscopic ultrasound revealed a cyst of the esophagus of 3.0 cm × 2.3 cm in size. Diagnostic laparoscopy was planned, during which we observed a para-esophageal cyst at the gastro-esophageal junction. Laparoscopic excision of this cyst was performed. Pathophysiological examination revealed an esophageal duplication cyst. We report a rare case of a symptomatic intra-abdominal esophageal duplication cyst in an adult. One must con-sider this diagnosis when more common diagnoses to account for the patient's symptoms are excluded. Re-moval of duplication cysts can be done laparoscopically. | Petrus Sebastianus Simon Castelijns Karlijn Woensdregt Brigiet Hoevenaars Gelde Arie Pieter Nieuwenhuijzen | 2014 | World Journal of Gastrointestinal Surgery2014,6,6: | 2 |
| 6 | 不同株行距和树形对高密度栽植樱桃产量的影响显示文摘优质樱桃的生产取决于品种、砧木、栽植密度、树形、树势、树龄、果实着生位置、果树负载量、农药和生长调节剂的使用等环境因素和农业技术管理措施。在樱桃的栽培管理中,应选择正确的授粉品种结合适合的砧木、树形和栽培密度。摩尔多瓦共和国的气候条件非常适合樱桃高密度栽培,但现在很多樱桃果园仍然是传统栽培模式。摩尔多瓦共和国政府为建立现代樱桃园的果农提供有吸引力的补贴,鼓励选择适宜的品种、砧木和树形,以实现果园现代化生产。 | Igor IVANOV Valerian BALAN Ananie PE?TEANU Sergiu VAMA?ESCU Petru BALAN Vasile ?ARBN 赵慧 | 2019 | 烟台果树2019,0,3: | 2 |
