Thunderbolt Technique: Novel Hemostatic Technique for Hemorrhage Related to Venous Infusion Catheter Drains

1 Sir: F its usefulness, cheapness, and scarless healing, drainage with a venous infusion catheter1,2 is used worldwide with some modifications. In our institute, this kind of drain is routinely used during implant-based breast reconstruction on patients with low risk of hematomas. Our method of preparation is very simple: peeling off one side of the outer plastic cannula of a 16-gauge venous i...

Naked Singularity and Thunderbolt

We consider quantum theoretical effects of the sudden change of the boundary conditions which mimics the occurrence of naked singularities. For a simple demonstration, we study a massless scalar field in (1 + 1)-dimensional Minkowski spacetime with finite spatial interval. We calculate the vacuum expectation value of the energy-momentum tensor and explicitly show that singular wave or thunderbo...

Basic overview of Thunderbolt Port (Interface)

Personal computers can be connected to peripheral devices using ports. Each port has an address of itself that is specific to it and is only accessed when called by the CPU. Different types of ports have different data carrying capacities. The fastest port available on present day PCs is the thunderbolt port. This review paper is dedicated to the understanding of the history, structure, uses an...

Thunderbolt in biogeochemistry: galvanic effects of lightning as another source for metal remobilization

Iron and manganese are relevant constituents of the earth's crust and both show increasing mobility when reduced by free electrons. This reduction is known to be controlled by microbial dissimilation processes. Alternative sources of free electrons in nature are cloud-to-ground lightning events with thermal and galvanic effects. Where thermal effects of lightning events are well described, less...
