The ideas of the Italian Renaissance were slow to cross the Alps into northern Europe, but important artistic innovations were made also in the Low Countries. Though not as previously believed the inventor of oil painting, Jan van Eyck was a champion of the new medium, and used it to create works of great realism and minute detail. The two cultures influenced each other and learned from each other, but painting in the Netherlands remained more focused on textures and surfaces than the idealized compositions of Italy.

The hole walls for boards with two or more layers can be made conductive and then electroplated with copper to form plated-through holes. These holes electrically connect the conducting layers of the PCB. For multi-layer boards, those with three layers or more, drilling typically produces a smear of the high temperature decomposition products of bonding agent in the laminate system. Before the holes can be plated through, this smear must be removed by a chemical de-smear process, or by plasma-etch. The de-smear process ensures that a good connection is made to the copper layers when the hole is plated through. On high reliability boards a process called etch-back is performed chemically with a potassium permanganate based etchant or plasma. The etch-back removes resin and the glass fibers so that the copper layers extend into the hole and as the hole is plated become integral with the deposited copper.
The process used on low-reliability boards is called what?
A: unanswerable

Because of its relative isolation from other Spanish-speaking areas over most of its 400-year existence, New Mexico Spanish, and in particular the Spanish of northern New Mexico and Colorado has retained many elements of 16th- and 17th-century Spanish and has developed its own vocabulary. In addition, it contains many words from Nahuatl, the language spoken by the ancient Aztecs of Mexico. New Mexican Spanish also contains loan words from the Pueblo languages of the upper Rio Grande Valley, Mexican-Spanish words (mexicanismos), and borrowings from English. Grammatical changes include the loss of the second person verb form, changes in verb endings, particularly in the preterite, and partial merging of the second and third conjugations.
Why is New Mexico always an after thought in American -Spanish speaking society?
A: Because of its relative isolation from other Spanish-speaking areas over most of its 400-year existence
