Lighting includes the use of both artificial light sources like lamps and light fixtures, as well as natural illumination by capturing daylight. Daylighting (using windows, skylights, or light shelves) is sometimes used as the main source of light during daytime in buildings. This can save energy in place of using artificial lighting, which represents a major component of energy consumption in buildings. Proper lighting can enhance task performance, improve the appearance of an area, or have positive psychological effects on occupants.

Indoor lighting is usually accomplished using light fixtures, and is a key part of interior design. Lighting can also be an intrinsic component of landscape projects.

Forms of lighting include alcove lighting, which like most other uplighting is indirect. This is often done with fluorescent lighting (first available at the 1939 World's Fair) or rope light, occasionally with neon lighting, and recently with LED strip lighting. It is a form of backlighting. 1. what is indoor lighing usually accomplished with?

Return to the Congo Mouth.

In the evening there was a palaver.

I need hardly say that my guide, after being paid to show me Nsundi, never had the slightest intention to go beyond the Yellala. Irritated by sleeping in the open air, and by the total want of hospitality amongst the bushmen, he and his moleques had sat apart all day, the picture of stubborn discontent, and

"Not a man in the place But had discontent written large in his face."

I proposed to send back a party for rum, powder, and cloth to the extent of 150, or half the demand, and my factotum, Selim, behaved like a trump. Gidi Mavunga, quite beyond self-control, sprang up, and declared that, if the Mundele would not follow him, that obstinate person might remain behind. The normal official deprecation, as usual, made him the more headstrong; he rushed off and disappeared in the bush, followed by a part of his slaves, the others crying aloud to him, "Wenda!"-- get out! Seeing that the three linguisters did not move, he presently returned, and after a furious address in Fiote began a Portuguese tirade for my benefit. This white man had come to their country, and, instead of buying captives, was bent upon enslaving their Mfumos; but that "Branco" should suffer for his attempt; no "Mukanda" or book (that is, letter) should go down stream; all his goods belonged of right to his guide, and thus he would learn to sit upon the heads of the noblesse, with much of the same kind. 1.

input: Make use of the article to answer the questions. (CNN) -- Serena Williams underlined her status as the overwhelming favorite for the women's U.S. Open title with a crushing "double bagel" win over Carla Suarez Navarro in the quarterfinals of the New York grand slam.

The defending champion, bidding for a fifth singles triumph at Flushing Meadows, beat the Spanish world No. 20 6-0 6-0 to become the first woman since Martina Navratilova in 1989 to win a women's U.S. Open quarterfinal without losing a game.

"I played well -- I played really well," world No. 1 Williams told the WTA's official website. "I was just more focused than anything.

"I like to believe there is always room for improvement though. I haven't really thought about it yet, but off the bat, I think it was very difficult to hit a big serve today because of the winds, and I didn't get my serve up as much as I wanted to. But I don't know. I do think I definitely played well tonight."

The American's latest commanding win means she has lost just 13 games at the tournament ahead of her semifinal meeting with Li Na, who is appearing in the last four of the year's final grand slam for the first time after beating Russia's Ekaterina Makarova.

"I'm still in the tournament and I'm not thinking like, 'I'm really dominant now'," added Williams. "I'm thinking I have a really tough match in the next round and want to do well."
