Output: unanswerable

QUES: A solar chimney (or thermal chimney, in this context) is a passive solar ventilation system composed of a vertical shaft connecting the interior and exterior of a building. As the chimney warms, the air inside is heated causing an updraft that pulls air through the building. Performance can be improved by using glazing and thermal mass materials in a way that mimics greenhouses.

What is a solar chimney made of?
What is the answer?
ANS: a vertical shaft connecting the interior and exterior of a building

QUES: This method involves coating LEDs of one color (mostly blue LEDs made of InGaN) with phosphors of different colors to form white light; the resultant LEDs are called phosphor-based or phosphor-converted white LEDs (pcLEDs). A fraction of the blue light undergoes the Stokes shift being transformed from shorter wavelengths to longer. Depending on the color of the original LED, phosphors of different colors can be employed. If several phosphor layers of distinct colors are applied, the emitted spectrum is broadened, effectively raising the color rendering index (CRI) value of a given LED.
The different colors of phosphors that can be used is based on what?

ANS: the color of the original LED

Cultural sociology first emerged in Weimar Germany (19181933), where sociologists such as Alfred Weber used the term Kultursoziologie (cultural sociology). Cultural sociology was then "reinvented" in the English-speaking world as a product of the "cultural turn" of the 1960s, which ushered in structuralist and postmodern approaches to social science. This type of cultural sociology may loosely be regarded as an approach incorporating cultural analysis and critical theory. Cultural sociologists tend to reject scientific methods,[citation needed] instead hermeneutically focusing on words, artifacts and symbols. "Culture" has since become an important concept across many branches of sociology, including resolutely scientific fields like social stratification and social network analysis. As a result, there has been a recent influx of quantitative sociologists to the field. Thus there is now a growing group of sociologists of culture who are, confusingly, not cultural sociologists. These scholars reject the abstracted postmodern aspects of cultural sociology, and instead look for a theoretical backing in the more scientific vein of social psychology and cognitive science. "Cultural sociology" is one of the largest sections of the American Sociological Association. The British establishment of cultural studies means the latter is often taught as a loosely distinct discipline in the UK.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Where did sociology culture become rejected?
Ah, so.. unanswerable

Question: Additionally, there are issues of connections between different electrical services, particularly connecting intercity lines with sections electrified for commuter traffic, but also between commuter lines built to different standards. This can cause electrification of certain connections to be very expensive simply because of the implications on the sections it is connecting. Many lines have come to be overlaid with multiple electrification standards for different trains to avoid having to replace the existing rolling stock on those lines. Obviously, this requires that the economics of a particular connection must be more compelling and this has prevented complete electrification of many lines. In a few cases, there are diesel trains running along completely electrified routes and this can be due to incompatibility of electrification standards along the route.
Try to answer this question if possible: What is the other issue that comes to sight when using electrification system?
Answer: connections between different electrical services

QUES: Solar concentrating technologies such as parabolic dish, trough and Scheffler reflectors can provide process heat for commercial and industrial applications. The first commercial system was the Solar Total Energy Project (STEP) in Shenandoah, Georgia, USA where a field of 114 parabolic dishes provided 50% of the process heating, air conditioning and electrical requirements for a clothing factory. This grid-connected cogeneration system provided 400 kW of electricity plus thermal energy in the form of 401 kW steam and 468 kW chilled water, and had a one-hour peak load thermal storage. Evaporation ponds are shallow pools that concentrate dissolved solids through evaporation. The use of evaporation ponds to obtain salt from sea water is one of the oldest applications of solar energy. Modern uses include concentrating brine solutions used in leach mining and removing dissolved solids from waste streams. Clothes lines, clotheshorses, and clothes racks dry clothes through evaporation by wind and sunlight without consuming electricity or gas. In some states of the United States legislation protects the "right to dry" clothes. Unglazed transpired collectors (UTC) are perforated sun-facing walls used for preheating ventilation air. UTCs can raise the incoming air temperature up to 22 C (40 F) and deliver outlet temperatures of 4560 C (113140 F). The short payback period of transpired collectors (3 to 12 years) makes them a more cost-effective alternative than glazed collection systems. As of 2003, over 80 systems with a combined collector area of 35,000 square metres (380,000 sq ft) had been installed worldwide, including an 860 m2 (9,300 sq ft) collector in Costa Rica used for drying coffee beans and a 1,300 m2 (14,000 sq ft) collector in Coimbatore, India, used for drying marigolds.
What are Unglazed transpired collectors?

ANS:
perforated sun-facing walls used for preheating ventilation air
