Use of genetically modified bacteria to repair cracks in concrete by Zhang, Zhigang, Weng, Yiwei, Ding, Yuanzhao, Qian, Shunzhi

“…The efficiency of crack-repairing in concrete by spraying two kinds of bacterial liquid was evaluated via image analysis, X-ray computed tomography (X-CT) scanning technology and the sorptivity test. The results show that the crack-repair efficiency was enhanced very evidently by spraying genetically modified bacterial-liquid as no microbiologically induced calcite precipitation (MICP) was found within the cracks for concrete samples sprayed using wild type bacterial-liquid. …”

Multi-angle data acquisition to compensate transducer finite size in photoacoustic tomography by Hakakzadeh, Soheil, Mozaffarzadeh, Moein, Mostafavi, Seyed Masood, Kavehvash, Zahra, Rajendran, Praveenbalaji, Verweij, Martin, de Jong, Nico, Pramanik, Manojit

“…To address this problem, we propose a multi-angle detection approach in which the transducer used for data acquisition rotates around its center (with specific angles) as well as around the scanning center. The angles are calculated based on the central frequency and diameter of the transducer and the radius of the region-of-interest (ROI). …”

Mechanics of fracture and flexure in Antarctic ice sheets and ice shelves by Zhang, H

“…In grounding zones and floating ice shelves, ice fracturing is often associated with flexure modulated by ocean tides and subglacial water flow, as well as stresses created by shearing, such as pinning points. Fracture and flexure significantly affect the vulnerability of Antarctic ice shelves to hydrofracturing and, by altering buttressing effects, the mass balance of the entire Antarctic Ice Sheet. …”
