<P>The stability of lithium salts, especially in the presence of reduced oxygen species, O<SUB>2</SUB> and H<SUB>2</SUB>O (even in a small amount), plays an important role in the cyclability and capacity of Li–O<SUB>2</SUB> cells. This combined experimental and computational study provides evidence that the stability of the electrolyte used in Li–O<SUB>2</SUB> cells strongly depends on the compatibility of lithium salts with solvent. In the case of the LiPF<SUB>6</SUB>–1NM3 electrolyte, the decomposition of LiPF<SUB>6</SUB> occurs in the cell as evidenced by <I>in situ</I> XRD, FT-IR and XPS analysis, which triggers the decomposition of 1NM3 solvent due to formation of HF from the decomposition of LiPF<SUB>6</SUB>. These reactions lead to degradation of the electrolyte and cause poor cyclability of the cell. The same reactions are not observed when LiTFSI and LiCF<SUB>3</SUB>SO<SUB>3</SUB> are used as the lithium salts in 1NM3 solvent, or LiPF<SUB>6</SUB> is used in TEGDME solvent.</P> <P>Graphic Abstract</P><P>We provided evidence that the stability of the electrolyte used in Li–O<SUB>2</SUB> cells strongly depends on the compatibility of lithium salts with solvent. <IMG SRC='http://pubs.rsc.org/services/images/RSCpubs.ePlatform.Service.FreeContent.ImageService.svc/ImageService/image/GA?id=c3cp50500f'> </P>

Immunoglobulin G4-related disease (IgG4-RD) is an immune-mediated fibroinflammatory condition involving the development of mass lesions of the affected organ, which can mimic many malignant disorders. IgG4-related autoimmune pancreatitis (AIP) is a common presentation form of IgG4-RD. Patients presenting with multiple mass lesions in the pancreas undergo aggressive surgeries with the misdiagnosis of pancreatic adenocarcinoma. A patient applied to the health center with back and stomach pain. She had two mass lesions involving the pancreatic head and tail; tumor markers were not significantly elevated. The patient underwent total pancreatoduodenectomy, total gastrectomy, and total splenectomy due to misdiagnosed pancreatic adenocarcinoma and developed severe morbidities afterward. She was diagnosed with IgG4-related AIP after surgery. On performing clini-cal suspicion the necessary diagnostic procedures for exclusion will protect patients from unnecessary surgeries that may lead to severe morbidities.
Behaviour of flush end-plate beam-to-column joints under bending and axial force
Luís Simões da Silva,Luciano R. O. de Lima,Pedro C. G. da S. Vellasco,Sebastião A. L. de Andrade 국제구조공학회 2004 Steel and Composite Structures, An International J Vol.4 No.2
Steel beam-to-column joints are often subjected to a combination of bending and axial forces. The level of axial forces in the joint may be significant, typical of pitched-roof portal frames, sway frames or frames with incomplete floors. Current specifications for steel joints do not take into account the presence of axial forces (tension and/or compression) in the joints. A single empirical limitation of 10% of the beam’s plastic axial capacity is the only enforced provision in Annex J of Eurocode 3. The objective of the present paper is to describe some experimental and numerical work carried out at the University of Coimbra to try to extend the philosophy of the component method to deal with the combined action bending moment and axial force.
Litigation in Vietnamese Criminal Procedure and the Judicial Reform
Lu’o’ng Thi My Quỳnh 전남대학교 법학연구소 2014 법학논총 Vol.34 No.1
Vietnam is actively implementing judicial reform strategy to 2020. To fit the generaltrend of the world integration, including orientation to complement the legal system,one of the priorities of judicial reform in Vietnam is: “Improving the quality of theprosecutors at trial, guaranteeing democratic litigation with lawyer, defense counsel andpeople involving in the proceedings…. The judgment of the Court must be basedprimarily on the results of litigation at the trial…”. By pointing out and analyzingspecific rules of Vietnam Criminal Procedure law, the author made comments andreviews on the role of litigation in Vietnam criminal proceedings in the context ofimplementing the judicial reform strategy.

Purpose: Patients receiving treatment for benign prostate hyperplasia may have persistent storage symptoms. There has been increasing debate on the precision and accuracy of the International Prostate Symptom Score questionnaires over other questionnaires in evaluating all the complaints of lower urinary tract symptoms (LUTS). The aim of this study was to perform the validity and reliability analysis of the Turkish version of the Internatinal Consultation on Incontinence Questionnaire-Male LUTS (ICIQ-MLUTS). Methods: Linguistic validation was studied (i.e., translation and back translation). Intelligibility was completed between October 2013 and November 2013. Data was collected between November 2013 and March 2014. The stability and reliability of the form were measured with the Cronbach test. Results: In total, 117 male patients were included in the study. At the first visit, the mean age of the patients was 59 years (range, 18–84 years). For reliability, the Cronbach alpha value was 0.798, demonstrating the internal consistency of the form (r>0.7). The internal consistency of each question was examined separately and found to be over 0.7. For the evaluation of test-retest reliability, the test was administered to 116 patients for a second time with an interval of 2–4 weeks. The first and second test scores for each question were found to be correlated (r=0.741). Conclusions: ICIQ-MLUTS is a new questionnaire, which can be used for evaluating male LUTS in Turkey. We believe that the Turkish version of the ICIQ-MLUTS is an important breakthrough in our country.
