Abstract The following article presents experimental use of different ways inguinal connecting aircraft elements using TIG (Tungsten Inert Gas), MAG (Metal Active Gas) and arched coated electrode. object the research were samples rotorcraft elements, which connected to each other by TIG, methods main aim was determine selected mechanical properties in particular hardness strength joints then, b...

Repair welding is not used enough in the industry 1 . One of the reasons for this lies in the insufficient and unrealiable knowledge in many segments of this area. A very important part is having appropriate knowledge of metallurgical processes in heating of the base material 2-4 . Unsuitable heating deteriorates the microstructure as it reduces toughness and fracture behaviour of the weld 5 . ...

The goal of this study was to determine how much the formation of tetanus antibody is influenced after a single injection of tetanus vaccine (Td) and the simultaneous injection of tetanus vaccine with tetanus immunoglobulin (TIG). All of the healthy adult volunteers were divided into two groups: group 1 (Td only) and group 2 (Td plus TIG). Two hundred thirty seven volunteers were enrolled. When...

Gas tungsten arc welding is fundamental in those industries where it is important to control the weld bead shape and its metallurgical characteristics. However, compared to the other arc welding process, the shallow penetration of the TIG welding restricts its ability to weld thick structures in a single pass (~ 2 mm for stainless steels), thus its productivity is relativity low. This is why th...

Two lines of immortal human fibroblasts were isolated following transfection of TIG-3 cells with plasmid DNA, pMT-1ODtsA, that contained SV40 early gene with a deletion in replication origin and ts mutation in coding sequence for T-antigen. These cells continued proliferation at 34 degrees C, over 565 population doubling level (PDL) which is far over the limited division potential of untransfor...
