Heavy metals adsorption by banana peels micro-powder: Equilibrium modeling by non-linear models

引用

Chinese Journal of Chemical Engineering 2018年第3期26卷 455-464页

作者： Giorgio Vilardi Luca di Palma nicola Verdone Sapienza University of Rome Department of Chemical Engineering Materials Environment

In this study the copper and lead adsorption efficiency onto banana peels powder was investigated. The agroindustrial waste recovery represents one of the Circular Economy pillars. In the view of the synthesis of an environmentally friendly adsorbent material, the powder was used without any preliminary chemical or thermal activation, but only after simple washing, drying and grinding. The bio-adsorbent was characterized by the FTIR technique and tested in batch mode on synthetic aqueous solutions containing Pb and Cu in the range 10–90 mg·L^(-1). A selection of two(Langmuir, Freundlich) and three(Sips, Redlich–Peterson, Koble–Corrigan) parameter isotherm models was chosen to fit adsorption equilibrium data by non-linear regression procedure. The best fit isotherm model was selected relying on the error function with the lowest average percentage error(APE) value, among those characterized by the highest R^2 values. As expected, the three-parameter models are found to better represent both metals bio-adsorption, with APE and R^2 values always lower and higher, respectively, than the corresponding values obtained for the two-parameter models.

From Alliance to Tutelage： A Historical Analysis of Manchu-Mongol Relations before the Qing Conquest

引用

Frontiers of History in China 2012年第2期7卷 175-197页

作者： nicola di Cosmo Institute for Advanced Study Princeton University Princeton NJ 08540 USA

Before 1644, the Manchu rulers pursued a deliberate policy of alliances with the southern （later ＂Inner＂） Mongol tribes. In the 1630s the system of treaties and alliances gave way to the creation of the League-Banner system, the jasaq system, and the Lifan Yuan. The new territorial and political organization meant that the southern Mongols, while retaining a degree of autonomy, became subjects of the Qing dynasty. This essay explores the historical circumstances of the transformation of the relationship between Manchus and Mongols from partnership to subordination. It also aims to explain the political principles deployed by the Manchus in the redefinition of their relationship with the Mongol elites. More specifically, the essay proposes that the new forms of administration of Inner Mongolia stemmed from a condition of ＂tutelage.＂ Tutelage was not simply imposed by the Manehus upon their erstwhile allies, but actively sought by Mongol aristocrats in the context of the intra-Mongol wars carried out by the Caqar leader Ligdan Khan.

Given the availability of several blockchain technologies in permissioned contexts,blockchain application designers have to cope with the increasing complexity of choosing which technology and consensus algorithm best fit a specific use ***,the lack of a standard framework allowing to assess the scalability of permissioned blockchain platforms and to compare performances and features of consensus algorithms makes the development of a sensible evaluation a costly and difficult time-consuming *** this article,we propose a practical scalability and applicability evaluation of the Quorum blockchain and its consensus *** we apply our evaluation workflow to a financial use case,we define a methodology that can be generalized to any permissioned blockchain *** leverage Hyperledger Caliper as a benchmarking tool,and Docker as a deployment tool,making our analysis easy to be repeated,cross-platform,and cost-effective.

Simultaneous endoscopic ultrasound fine needle aspiration and endoscopic retrograde cholangio-pancreatography:Evaluation of safety

引用

World Journal of Gastroenterology 2007年第28期13卷 3861-3863页

作者： Ilaria Tarantino Luca Barresi marta di Pisa Mario Traina Istituto Mediterraneo Trapianti e Terapie ad alta specializzazione University of Pittsburgh Medical CenterItaly

AIM: To investigate the rate of complications of endoscopic retrograde cholangio-pancreatography (ERCP) performed immediately after endoscopic ultrasound fine needle aspiration (EUS-FNA) in a large series of patients. METHODS: Patients with the following conditions were considered candidates for EUS-FNA and ERCP: diagnosis of locally advanced or metastatic pancreatic lesion not eligible for surgery, and patients with pancreatic lesion of unknown nature causing jaundice. Data were prospectively collected on the following parameters: indication for FNA, EUS findings, pathological diagnosis, procedure duration of EUS-FNA and combined EUS-FNA and ERCP, and immediate and late complications. RESULTS: From January 2004 to October 2006, 72 patients were deemed eligible for combined EUS and ERCP. In 25/72 EUS-FNA was performed to obtain a pathology diagnosis of lesions causing biliary obstruction, and ERCP sequentially performed to drain the biliary system. No immediate complications occurred except for two mild bleeding episodes post sphincterotomy. No late complications were recorded except for one patient who experienced fever, promptly recovered with antibiotic therapy. CONCLUSION: Simultaneous approach appears to be feasible and safe. When possible, this can be considered the reference standard to avoid double sedation and reduce duration of the procedure and hospital stay.

High prevalence of nonalcoholic fatty liver in patients with idiopathic venous thromboembolism

World Journal of Gastroenterology 2010年第48期16卷 6119-6122页

作者： Matteo nicola Dario di Minno Antonella Tufano Anna Rusolillo Giovanni di Minno Giovanni Tarantino Department of Clinical and Experimental Medicine Federico II University Medical School of Naples

AIM:To assess the prevalence of nonalcoholic fatty liver disease (NAFLD) in patients with idiopathic venous thromboembolism (VTE). METHODS:In a case-control study,after excluding subjects with well-consolidated risk factors for VTE,idiopathic VTE was documented in 138 consecutive patients who were referred to our department. Two hundred and seventy-six healthy sex/age/body-massindex-matched subjects,without any clinical/instrumental evidence of VTE,served as controls. All underwent a clinical/laboratory/ultrasound assessment for the presence of metabolic syndrome and NAFLD. RESULTS:NAFLD was detected in 112/138 cases (81%) and in 84/276 controls (30%) [risk ratio:2.7,95% confidence interval (CI):2.2-3.2,P diopathic VTE. The high prevalence of NAFLD in VTE was also confirmed after adjustment for inherited thrombophilia. NAFLD was clearly predicted by VTE (odds ratio:1.8,95% CI:1.2-2.7,P < 0.0001).
