Giant Cell Tumor of Talus – Role of imaging

Giant cell tumor (GCT) or Osteoclastoma of the tarsal bone is very rare as compared to that of long bones. The involvement of talus becomes unique in its presentation as it remains undiagnosed for a long time. The tumor usually occurs in younger age especially in small bones of hands and feet. We present a case of 34-years old male who presented with sprain of left foot and was finally diagnosed as giant cell tumor of the talus. This was possible with the help of various radiological modalities like plain X-ray, computerised tomography (CT) and magnetic resonance imaging (MRI). GCT of talus may be found as an incidental finding but the subsequent management depends upon the staging of the tumor as per the radiological evaluation

Bar On Phoenix Arrangements: An Analysis Of Layers Of Ineligibility Under Section 29a

When the Insolvency & Bankruptcy Code, 2016, came out three years ago, it brought with it a promise of an efficient, modern means for lenders of Corporate Debtors to realize the amount owed to them. At the same time, it offered an alternative to liquidation. However, while the Code seemed impressive on paper when it came to its application, the realization set in that there were countless questions to be answered through judicial interpretation. And ever since then, the lenders, corporate debtors, promoters, and all other concerned parties have been involved in back-to-back litigation. Where questions of interpretation can be expected to follow the introduction of any new legislation, one must wonder whether the implementation of the Code could have been done in a better way or whether its drafters could have given its provisions more clarity. Is the Insolvency & Bankruptcy Code, 2016 effective in meeting its objectives as it has been made to appear? After giving a brief overview of the history of the Code, this paper dwells into the issue of phoenixing under Section 29A and the layers of ineligibilities it has introduced. The paper throws light on the scope and nature of Section 29A and the bidding paradox present in the system. This is followed by an assessment of the overall impact of the Code as per the currently available data and a concluding note

Possible phase transformation toughening of thermoset polymers by poly(butylene terephthalate)

Mechanisms were explored by which particles of poly(butylene terephthalate) (PBT) are able to toughen a brittle epoxy. The epoxy studied was an aromatic amine-cured diglycidyl ether of bisphenol-A, which was toughened at about twice the rate with particles of poly(butylene terephthalate) as with particles of nylon 6, poly(vinylidene fluoride), or CTBN rubber. Many of the mechanisms of toughening are visible on the fracture surface of the PBT-epoxy blend, but a mechanism suggested to account for perhaps half of the increased toughness with PBT, phase transformation toughening, is not. The two types of experiment performed to detect phase transformation toughening were: (1) measurements of the rubber cavitation zone in PBT-CTBN rubber-epoxy ternary blends, which would detect an expansion of the PBT particles during fracture if it occurred, and (2) measurements of the fracture energy in PBT-epoxy blends in which the various mechanisms of toughening were selectively suppressed. Both types of experiment indicated the occurrence of phase transformation toughening in these PBT-epoxy blends.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/44711/1/10853_2005_Article_BF01154110.pd
