Sao Paulo Med J/Rev Paul Med 2002; 120(2):35. The history of lung cancer spans many years, and over recent decades excision of tumors has been considered as the only effective treatment. In 1933 Graham performed the first successful pneumonectomy due to lung cancer. In 1937 Ochsner and DeBakey first concluded that smoking is a cause of lung cancer. This important observation was confirmed by Do...

ABSTRACT The Central Molecular Zone (the central ∼500 pc of the Milky Way) hosts molecular clouds in an extreme environment strong shear, high gas pressure and density, complex chemistry. G0.253+0.016, also known as ‘the Brick’, is densest, most compact, quiescent these clouds. High-resolution observations with Atacama Large Millimetre/submillimetre Array (ALMA) have revealed its complex, hiera...

We generalize the brick polytope of V. Pilaud and F. Santos to spherical subword complexes for finite Coxeter groups. This construction provides polytopal realizations for a certain class of subword complexes containing all cluster complexes of finite types. For the latter, the brick polytopes turn out to coincide with the known realizations of generalized associahedra, thus opening new perspec...

We consider the thermodynamics of minimally coupled massive scalar field in 3+1 dimensional constant curvature black hole background. The brick wall model of ’t Hooft is used. When Scharzschild like coordinates are used it is found that apart from the usual radial brick wall cut-off parammeter an angular cut-off parameter is required to regularize the solution. Free energy of the scalar field i...

Time-dependent natural weathering processes suffered by historic bricks in Toledo (Spain) improve their physicomechanical properties by porous infill with gypsum, ettringite and mainly calcite. Both, these bricks and their experimental replica bricks, made from the original calcareous clays fired at the probable historical temperatures (700o 900oC), have been analyzed by X-ray diffraction, opti...

(2) a. These blockages can grow instance by instance, cycle by cycle, stone after stone, lifetime after lifetime, until the body starts to manifest these issues as disease b. Brick upon brick, stone upon stone they grow. c. She laid book upon book and built a staircase long enough to climb up and look over the wall. d. This mystery offers puzzle within puzzle. e. The Wall of Tears is a very big...

A promising application of DNA self-assembly is the fabrication of chromophore-based excitonic devices. DNA brick assembly is a compelling method for creating programmable nanobreadboards on which chromophores may be rapidly and easily repositioned to prototype new excitonic devices, optimize device operation, and induce reversible switching. Using DNA nanobreadboards, we have demonstrated each...
