Glass Floor Plate Design for Sustainable Building Operation

Large glass floor plates are usually designed as laminates of three or more glassleaves, bonded together with an interlayer. This means that, in the event ofaccidental breakage, the entire plate must be replaced, sometimes at considerablecost. In addition, where access is difficult, the costs and the disruption to theowner’s operations are increased. Finally, it is difficult to recycle laminated glass.An alternative is outlined whereby a sacrificial layer is loose laid on top of thestructural laminate. In the event of breakage, only this top layer is replaced, withthe lower structural laminate remaining in place to provide safety throughout theoperation. This design differs from the conventional construction where the topsheet is bonded to the rest. An in situ trial was carried out, and this proved theeffectiveness of the loose laid approach

Lung Cancer Associated with Sarcoidosis - A case report -

Sarcoidosis is a somewhat common pulmonary disease, but the concurrence of lung cancer and sarcoidosis in the same patient is very rare. Because sarcoidosis usually presents as mediastinal lymphadenopathies, this concurrence in a lung cancer patient detected radiologically is apt to be misunderstood to be mediastinal metastases, and it is thus considered to be an unresectable disease. We report a case of lung cancer associated with sarcoidosis that developed in a 65-year-old woman who underwent surgery. Radiological studies revealed a 1.9×1.7 cm mass in the left upper lobe with multiple enlarged bilateral mediastinal lymph nodes (2R, 3a, 4R, 4L, 5, 6, 7, 8R). Pathologic findings showed that the mass was a well-differentiated adenocarcinoma and all of the enlarged mediastinal lymph nodes were granulomas without cancer metastasis. We report this case with a review of the literature
