  • Automation is also important to replace the skilled workers. Welding is one of the most important jobs in shipyards, and the ratio of the mechanized welding in Japanese shipyards is 42% in average, and 64% in the most advanced shipyard (Miyazaki 2008). Further development of mechanized welding calls for a breakthrough. Miyazaki (2008) showed some challenges such as mechanized welding inside the double hull structure in the assembly stage, and mechanized butt welding of longitudinals inside the double hull structure in the erection stage.

  • Complex IV is the terminal enzyme of the mitochondrial respiratory chain. In humans, biogenesis of complex IV involves the coordinated assembly of 13 subunits encoded by both mitochondrial and nuclear genomes. The early stages of complex IV assembly involving mitochondrial DNA-encoded subunits CO1 and CO2 have been well studied.

  • Recent experiences from carrying out Design for Assembly (DFA) and Design for Manufacture (DFM) product studies in industry have reinforced the authors’ belief that consideration of manufacturing problems at the design stage is the major means available for improving product quality, reducing manufacturing costs and increasing productivity. In the second edition, as well as providing further information to help select processes for components and the joining of components, we have included data on assembly process selection and costing.

  • I hope the reader will find inspiration from the new concepts described in this work. What is presented is a new approach to the metallurgy of castings. Not everything in the book can claim to be proved at this stage. Ultimately, science proves itself by underpinning good technology. Thus, not only must it be credible but, in addition, it must really work. Perhaps we may never be able to say for certain that it is really true, but in the meantime it is proposed as a piece of knowledge as reliable as can now be assembled (Ziman 2001)....

  • Get started with MintDuino, the Maker Shed kit that's perfect for learning or teaching the fundamentals of how microcontrollers work. This hands-on book shows you how to build a complete MintDuino project from start to finish. Learn how to assemble the microcontroller on a breadboard (no soldering required), and immediately begin programming it. You'll build the MintDuino Reflex Game in five separate stages or sub-tasks. Breaking down a large project into manageable tasks helps you track down errors quickly...

  • In today’s environment,manufacturing businesses are facing fierce competition and operating in changing markets. Customer demands for higher quality products at lower costs and shorter product lifecycles are putting extra pressure on the product introduction process. Cost and quality are essentially designed into products in the early stages of this process.

  • Lean production is based on the logic that nothing will be produced until it is needed. Need is created by an actual demand for the product. When an item is sold, in theory, the market pulls a replacement from the last position in the system or final assembly. This triggers an order to the production line which generates orders at upstream work stations. Lean demands high levels o quality at each stage of the process, strong vendor relations, and a fairly predictable demand for the end product.

  • The elongation phase of mRNA translation is the stage at which the polypeptide is assembled and requires a substantial amount of metabolic energy. Translation elongation in mammals requires a set of nonribosomal proteins called eukaryotic elongation actors or eEFs. Several of these proteins are subject to phosphorylation in mammalian cells, including the factors eEF1A and eEF1B that are involved in recruitment of amino acyl-tRNAs to the ribosome.
