| 1 | Geometry of screw compressor rotors and their tools显示文摘This paper presents a method of general geometrical definitions of screw machine rotors and their manufacturing tools.It describes the details of lobe shape specification,and focuses on a new lobe profile,which yields a larger cross-sectional area and shorter sealing lines resulting in higher delivery rates for the same tip speed.A well proven mathematical model was used to determine the optimum profile,compressor housing size,and compressor ports to achieve the superior compressors. | Nikola STOSIC Ian K.SMITH Ahmed KOVACEVIC Elvedin MUJIC | 2011 | Journal of Zhejiang University-Science A(Applied Physics & Engineering)2011，12，4： | 14 |

| 3 | Modalities of testing Helicobacter pylori in patients with nonmalignant bile duct diseases显示文摘AIM: This paper describes the procedure of detection ofHelicobacter pylori ( H. pylori) in bile specimens in patientssuffering from benign diseases of biliary ducts (lithiasiswith/without nonspecific cholangitis).METHODS: The group of 72 patients entering the studyconsisted of 32 male and 40 female (45 % and 55 %,respectively). Bile was obtained during ERCP in 68 patients,and during cholecystectomy in 4 patients. A fast urease test(FUT) to determine the existence of H. pylori in gastricmucosa was carried out for all the patients during theendoscopic examination. The existence of genetic materialof H. pylori was determined by detection of ure A gene bythe method of nested PCR. The results of this reaction wereshown by electrophoresis on l0 g@ L-1 agarose gel in a bandof 256 bp.RESULTS: The majority of the patients included in our studyhad biliary lithiasis without signs of cholangitis (48 patients,67 %), whereas other patients were complicated bycholangitis (17 patients, 24 %). Seven patients (9 %) hadnormal ERCP, forming thus the control group. In the groupof patients with lithiasis 26 patients (54.2 %) had positivePCR of H. pylori in bile and among the patients withassociated cholangitis positive PCR was detected in 9patients (52.9 % ). Among the seven patients with nornalERCP only one (14 %) had positive PCR of H. pylori. Ahigh percentage of H. pylori infection of gastric mucosawas observed (57 patients, 79 % ) : It was also observed thatits slightly higher positivity was in the patients with distinctbile pathology: 81% FUT positive patients in the group withcholedocholithiasis alone and 76 % in the group withcholedocholithiasis associated with cholangitis. Seventy-onepercent of the patients with regular findings had positive FUT.CONCLUSION: The prevalence of H. pylori infection both inbile and in gastric mucosa in patients with benign diseasesof biliary ducts does not show a statistically significantdifference in relation to the prevalence of the same with thepatients with normal ERCP. The existence of H. pyloriinfection possibly does not play a role in pathogenesis ofbenign biliary diseases. | Milutin Bulajic Bojan Stimec Miroslav Milicevic Matthias Loehr Petra Mueller Ivan Boricic Nada Kovacevic Mirko Bulajic | 2002 | World Journal of Gastroenterology2002，8，2： | 6 |
| 4 | Biochemical markers for non-invasive assessment of disease stage in patients with primary biliary cirrhosis显示文摘AIM: To evaluate different biochemical markers and their ratios in the assessment of primary biliary cirrhosis (PBC) stages. METHODS: This study included 112 patients with PBC who underwent a complete clinical investigation. We analyzed the correlation (Spearman's test) between ten biochemical markers and their ratios with different stages of PBC. The discriminative values were compared using areas under receiver operating characteristic (ROC) curves. RESULTS: The mean age of patients included in the study was 53.88 ± 10.59 years, including 104 females and 8 males. We found a statistically significant correlation between PBC stage and Aspartate aminotransferase (AST), Alanine aminotransferase (ALT) to platelet ratio (APRI), ALT/platelet count, AST/ALT, ALT/AST and ALT/Cholesterol ratios, with the values of Spearman's rho of 0.338, 0.476, 0.404, 0.356, 0.351 and 0.325, respectively. The best sensitivity and specificity was shown for AST/ALT, with an area under ROC of 0.660. CONCLUSION: Biochemical markers and their ratios do correlate with different sensitivity to and specificity of PBC disease stage. The use of biochemical markers and their ratios in clinical evaluation of PBC patients may reduce, but not eliminate, the need for liver biopsy. | Tamara Alempijevic Miodrag Krstic Rada Jesic Ivan Jovanovic Aleksandra Sokic Milutinovic Nada Kovacevic Slobodan Krstic Dragan Popovic | 2009 | World Journal of Gastroenterology2009，15，5： | 4 |

| 9 | Sustainable development of lignite production on open cast mines in Serbia显示文摘Energy sector represents a key industrial branch for national, environmental and economic success. With its exclusive access to domestic deposits, lignite industry represents a guarantor of reliable raw materials, offering long-term supply security based on verified reserves. Currently operated coalmines in Serbia (Kolubara and Kostolac) have production around 36 million tons of lignite, and over 108 million m3 of overburden. Consequently, sustainability of lignite production requires cost reduction and environmental protection, as well as capacity increase. In order to rationalise, and increase efficiency of Serbian lignite mines, it is necessary to focus the activities on major issues shown within the triangle of energy policy objectives (security of supply, competi- tive prices and environmental protection). Production process optimisation singled out several special programs. Equipment revi- talization and modernization is necessary taking into account that majority of the currently operated machinery has a life up to 25 years. Production process automation would enable high level of technical operation in the field of open cast mines management. Lack of coal quality uniformity is the permanent problem resulting by great amounts of coal reserves to be used uneconomically. Planning and training at all levels and finally cooperative software for business procedures and work order management. The measures suggested are a key precondition for maintaining competitive position of lignite production on international level. | DANICIC Darko MITROVIC Slobodan PAVLOVIC Vladimir KOVACEV Sava | 2009 | Mining Science and Technology2009，19，5： | 2 |
