In What is a Low-Carb Diet?, I outline three approaches to low-carb eating, only one of which focuses on ketosis as a goal throughout the diet. Diets such as the Atkins Diet start out as a very low-carb ketogenic diet, but as people add carbohydrate, many or most will be eating too much carbohydrate to be in ketosis.
At the core of any custom motorcycle project is the welding process used to join the tubing that makes up the bike's frame. This article will discuss how both MIG and TIG welding fit into this process and how even a novice welder can get started. (As seen in the Welding Journal, October 2005)
An advantage of this provisionalassembly procedure is that if the alignment for final welding is found to be incorrect, the parts can be disassembled easily, realigned, and tack welded again. In general, tack welding is performed by the same process that is used for the final weld. For example, aluminum-alloy assemblies to be joined by friction stir welding are tack-welded by the same process using a small tool developed for this purpose.
