The Influence of Effective Factors on Mechanical Stress on Fingertips During Snap-fit Assembly

Objectives: Nowadays, Snap-fits are used in the automotive industry as a proper alternative for mechanical joints, cabling joints, and car interior lining joints. Due to the special form of these joints, which are assembled manually, the contact area between Snap-fits and the worker’s fingertips can be too small. This can cause skin pain on the worker’s  fingertips. Therefore, ...

Observations on PCB Assembly Optimization

At the top of operational and tactical levels is the scheduling problem. It is here where decisions are made on how to operate machinery to produce a set of different PCBs (usually how to execute the weekly production plan). The next hierarchy level includes grouping and line balancing problems. For the linebalancing problem, the challenge is balancing the workload of different machines when pr...

RNA interference and heterochromatin assembly.

In most eukaryotes, histone and DNA modifications are responsible for the silencing of genes integrated in heterochromatic sequences, as well as the silencing of pericentromeric repeats and transposable elements themselves. But the mechanisms that guide these modifications to heterochromatin during the cell cycle have been elusive. RNA interference takes advantage of heterochromatic transcripti...
