| 1 | Liver abscess and sepsis with Bacillus pantothenticus in an immunocompetent patient:A first case report显示文摘Bacillus species are aerobic,gram-positive,spore forming rods that are usually found in the soil,dust,streams,and other environmental sources.Except for Bacillus.anthracis(B.anthracis) ,most species display low virulence,and only rarely cause infections in hosts with weak or damaged immune systems.There are two case reports of B.cereus as a potentially serious bacterial pathogen causing a liver abscess in an immunologically competent patient.We herein report a case of liver abscess and sepsis caused by B.pantothenticus in an immunocompetent patient.Until now,no case of liver abscess due to B.pantothenticus has been reported. | Jung Sik Na Tae Hyung Kim Heung Su Kim Sang Hyun Park Ho Sup Song Sang Woo Cha Hee Jung Yoon | 2009 | World Journal of Gastroenterology2009，15，42： | 0 |
| 2 | Effect of solid-solution strengthening on deformation mechanisms and strain hardening in medium-entropy V_(1-x)Cr_(x)CoNi alloys显示文摘High-and medium-entropy alloys(HEAs and MEAs)possess high solid-solution strength.Numerous investigations have been conducted on its impact on yield strength,however,there are limited reports regarding the relation between solid-solution strengthening and strain-hardening rate.In addition,no attempt has been made to account for the dislocation-mediated plasticity;most works focused on twinning-or transformation-induced plasticity(TWIP or TRIP).In this work we reveal the role of solidsolution strengthening on the strain-hardening rate via systematically investigating evolutions of deformation structures by controlling the Cr/V ratio in prototypical V_(1-x)Cr_(x)CoNi alloys.Comparing the TWIP of CrCoNi with the dislocation slip of V_(0.4)Cr_(0.6)CoNi,the hardening rate of CrCoNi was superior to slip-band refinements of V_(0.4)Cr_(0.6)CoNi due to the dynamic Hall-Petch effect.However,as V content increased further to V_(0.7)Cr_(0.3)CoNi and VCoNi,their rate of slip-band refinement in V_(0.7)Cr_(0.3)CoNi and VCoNi with high solid-solution strength surpassed that of CrCoNi.Although it is generally accepted in conventional alloys that deformation twinning results in a higher strain-hardening rate than dislocation-mediated plasticity,we observed that the latter can be predominant in the former under an activated huge solid-solution strengthening effect.The high solid-solution strength lowered the cross-slip activation and consequently retarded the dislocation rearrangement rate,i.e.,the dynamic recovery.This delay in the hardening rate decrease,therefore,increased the strain-hardening rate,results in an overall higher strain-hardening rate of V-rich alloys. | Hyun Chung Dae Woong Kim Woo Jin Cho Heung Nam Han Yuji Ikeda Shoji Ishibashi Fritz Körmann Seok Su Sohn | 2022 | Journal of Materials Science & Technology2022，，13： | 0 |
