Continuous biodiesel production from a waste pig-roasting lard,methanol and KOH was carried out in a reciprocating plate reactor(rPr)using a factorial design containing three process factors,namely methanol/lard molar ratio,catalyst loading,and normalized height of the *** main goals were to optimize the influential process factors with respect to biodiesel purity using the response surface methodology and to model the kinetics of the transesterification reaction in order to describe the change of triacylglycerols(TAG)and fatty acid methyl esters(FAME)concentrations along the rPr *** first-order rate law was proved for both the reaction and the mass *** model of the changing reaction mechanism and mass transfer of TAG was also *** kinetic models agreed with the experimental concentrations of TAG and FAME determined along the rPr height.

Behavior of the relativistic angular and energy distributions of atoms exposed to a strong and low-frequency circularly polarized laser field

引用

Chinese Optics Letters 2015年第7期13卷 14-17页

作者： Tatjana B.miladinovic Violeta M.Petrovic Department of Physics Faculty of Science Kragujevac University

In this Letter, we focus on the theoretical analysis of the relativistic energy and angular distributions of the ejected photoelectrons during the relativistic tunnel ionization of atoms by intense, circularly polarized light. We make a small modification of the general analytical expressions for these distributions. The role of the initial momentum, the ponderomotive potential, and the Stark shift are considered. We also present the maximal angle of electron emission.

Student-Teacher Communication in University Teaching

Sino-US English Teaching 2013年第1期10卷 65-71页

作者： radmila Suzic Tijana Dabic Ivana Cirkovic miladinovic "Bijeljina" University Bijeljina Bosnia and Herzegovina "Sinergij a" University Bijeljina Bosnia and Herzegovina University of Kragujevac Kragujevac Serbia

Considering that communication is an extremely important element in modem university education, it is of utmost importance to know how successful student-teacher communication can be achieved. In an attempt to explain it, this paper gives a definition of educational communication focusing on key aspects of student-teacher relationship and development of skills necessary for complete and independent communication. Student-teacher relationship is mostly determined by the first contact, as explained in Heider＇s attribution theory, because assigning attributes to other people and trying to understand their behavior is essential part of human nature. Through the example of pedagogical workshops, the paper demonstrates the importance of the interactive learning at university level, which leads towards establishing effective communication between teachers and *** that communication is an extremely important element in modem university education, it is of utmost importance to know how successful student-teacher communication can be achieved.

Comparative effectiveness of traditional chemoembolization with or without sorafenib for hepatocellular carcinoma

World Journal of Hepatology 2013年第7期5卷 364-371页

AIM: To compare the overall survival (OS) and progression-free survival (PFS) with associated adverse events (AE) in patients with unresectable hepatocellular carcinoma (HCC) treated with transarterial chemoembolization (TACE) + sorafenib vs TACE alone. METHODS: In this retrospective cohort study we collected data on all consecutive patients with a diagnosis of unresectable HCC between 2007 and 2011 who had been treated with TACE + sorafenib or TACE alone. We hypothesized that the combination therapy is superior to TACE alone in improving the survival in these patients. Data extracted included patient's demographics, etiology of liver disease, histology of HCC, stage of liver disease with respect to model of end stage liverdisease score and Child-Turcotte-Pugh (CTP) classification and Barcelona Clinic Liver Cancer (BCLC) staging for HCC. Computed tomography scan findings, alpha fetoprotein levels, number of treatments and related AE were also recorded and analyzed. rESULTS: Of the 43 patients who met inclusion criteria, 13 were treated with TACE + sorafenib and 30 with TACE alone. There was no significant difference in median survival: 20.6 mo (95%CI: 13.4-38.4) for the TACE + sorafenib and 18.3 mo (95%CI: 11.8-32.9) for the TACE alone (P = 0.72). There were also no statistically significant differences between groups in OS (Hr = 0.82, 95%CI: 0.38-1.77; P = 0.61), PFS (Hr = 0.93, 95%CI: 0.45-1.89; P = 0.83), and treatment-related toxicities (P = 0.554). CTP classification and BCLC staging for HCC were statistically significant (P = 0.001, P = 0.04 respectively) in predicting the survival in patients with HCC. The common AE observed were abdominal pain, nausea, vomiting and mild elevation of liver enzymes. CONCLUSION: Combination therapy with TACE + sorafenib is safe and equally effective as TACE alone in patients with unresectable HCC. CTP classification and BCLC staging were the significant predictors of survival. Future trials with large number of patients are nee
