Question: The earliest recorded history of the region dates back to about 500 BCE when much, if not all, of modern Tajikistan was part of the Achaemenid Empire. Some authors have also suggested that in the 7th and 6th century BCE parts of modern Tajikistan, including territories in the Zeravshan valley, formed part of Kambojas before it became part of the Achaemenid Empire. After the region's conquest by Alexander the Great it became part of the Greco-Bactrian Kingdom, a successor state of Alexander's empire. Northern Tajikistan (the cities of Khujand and Panjakent) was part of Sogdia, a collection of city-states which was overrun by Scythians and Yuezhi nomadic tribes around 150 BCE. The Silk Road passed through the region and following the expedition of Chinese explorer Zhang Qian during the reign of Wudi (141–87 BCE) commercial relations between Han China and Sogdiana flourished. Sogdians played a major role in facilitating trade and also worked in other capacities, as farmers, carpetweavers, glassmakers, and woodcarvers.

Question: Subtractive methods remove copper from an entirely copper-coated board to leave only the desired copper pattern. In additive methods the pattern is electroplated onto a bare substrate using a complex process. The advantage of the additive method is that less material is needed and less waste is produced. In the full additive process the bare laminate is covered with a photosensitive film which is imaged (exposed to light through a mask and then developed which removes the unexposed film). The exposed areas are sensitized in a chemical bath, usually containing palladium and similar to that used for through hole plating which makes the exposed area capable of bonding metal ions. The laminate is then plated with copper in the sensitized areas. When the mask is stripped, the PCB is finished.

Question: Shift-work or chronic jet-lag have profound consequences on circadian and metabolic events in the body. Animals that are forced to eat during their resting period show increased body mass and altered expression of clock and metabolic genes.[medical citation needed] In humans, shift-work that favors irregular eating times is associated with altered insulin sensitivity and higher body mass. Shift-work also leads to increased metabolic risks for cardio-metabolic syndrome, hypertension, inflammation.
Try to answer this question if possible: What causes animals to have decreased body mass?
Answer: unanswerable
Question: In the mid 1970s, various American groups (some with ties to Downtown Manhattan's punk scene, including Television and Suicide) had begun expanding on the vocabulary of punk music. Midwestern groups such as Pere Ubu and Devo drew inspiration from the region's derelict industrial environments, employing conceptual art techniques, musique concrète and unconventional verbal styles that would presage the post-punk movement by several years. A variety of subsequent groups, including New York-based Talking Heads and Boston-based Mission of Burma, combined elements of punk with art school sensibilities. In 1978, the former band began a series of collaborations with British ambient pioneer and ex-Roxy Music member Brian Eno, experimenting with Dada-influenced lyrical techniques, dance music, and African polyrhythms. San Francisco's vibrant post-punk scene was centered around such groups as Chrome, the Residents and Tuxedomoon, who incorporated multimedia experimentation, film and ideas from Antonin Artaud's Theater of Cruelty.
