The sludge volume index of activated sludge is defined as the volume in milliliters occupied by one gram of activated sludge after settling for 30 minutes. From this definition it may be observed that the lower the SVI, the better is the settling quality of the aerated mixed liquor. Also, high SVI values (greater than 100) indicate poor settling qualities and possible bulking problems in the secondary clarifier. Sludge with an SVI of less than 100 is considered a good settling sludge. Ideally you are looking for a value that ranges from 50 to 75 for most conventional activated sludge plants. You should be aware of the fact that SVI or SDI are classical measurements of sludge quality, but may or may not always reflect the true sludge conditions and must be compared with other process parameters, such as sludge units.

Digested sludge / Sludge Volume Index (SVI) test

Mazda Motor Corporation assembles the Mazda3, an automobile model (known in Japan as the Axela), and offers it to the public under the Mazda brand. Based on the MX-Sportif's concept stylings, the new 2004 Mazda3 replaces the Mazda Protegé.

Chassis development was carried out by Mazda and suspension designed by Ford. The Mazda3/Axela is available in two different bodyworks, a four-door sedan, marketed as "coupé style" in Europe, and a five-door hatchback, branded the Sport version in America and Japan.

Lou hei @ 907 coffeeshop
Yusheng (Chinese: 鱼生; Hanyu Pinyin: yúshēng) is a Chinese-style raw fish salad. It usually consists of strips of raw fish (most commonly salmon), mixed with shredded vegetables and a variety of sauces and condiments, among other ingredients. Literally translated, "yusheng" means "raw fish", though it can also be taken to symbolise abundance, prosperity and vigour.
It is a custom for families and friends to gather around the table and, on cue, proceeding to toss the shredded ingedients into the air with chopsticks while saying 吉祥话 (Jíxiáng Huà, auspicious wishes) out loud.
Typical ingredients include: fresh salmon, daikon (white radish), carrot, red pepper (capsicum), ginger, kaffir lime leaves, chinese parsley, chopped peanuts, toasted sesame seeds, Chinese shrimp crackers (or fried dried shrimp), five spice powder. The dressing is made primarily from plum sauce.

Seems like this entry was not updated properly, & another entry completed disappeared. I guesss I must have quit the browser by mistake. Sigh. Oh well, it was a Friday & it seems like it's the onnly day where all of us can have a common lunch break. So rather than compete with the lunchtime mad rush, we decided to eat outside of campus for a change in environment. Went to 907 coffeeshop, which is fast becoming out favourite haunt outside of school, in 2 nos cars because se7en & jasjas got drive today.
Zoom zoom, fast forward to the coffeeshop. Someone how suggested we have out own mini lou hei, so we asked what sizes does the yusheng come in & how much do they cost. the uncle said the small yushend cost 188. I was like WTF!!! got gold inside ah? He clarified that it cost 18.80sgd lah,. KNNCCB, say properly lah, not everyone understands your freaking lingo loh.
We also ordered an individual dish like hor fun or fried rice to complement the yusheng, & needless to say, afterlunch, we were stuffed. Hope we don't fall asleep in lecture later. Heez.

The Ring Bearer
In The Lord of the Rings, by J. R. R. Tolkien, Frodo Baggins is appointed to be the Ring-bearer by the Council of Elrond in Rivendell. He was to carry the One Ring from Rivendell to the Crack of Doom in Mordor and destroy it before Sauron's minions, the Ringwraiths could retrieve it for their Dark Lord.
The title is also given to two other hobbits who carried the One Ring. They were Bilbo Baggins and Frodo's companion Sam Gamgee (who carried it briefly in Mordor). Because of their position as Ring-bearers, they were granted the right to travel to the Undying Lands.
Others bore the Ring during its existence, but were not classified as Ring-bearers. They include:
* Sauron, who made it.
* Isildur, who cut it from Sauron's finger and wore it until it slipped off into the Gladden
river just before his death.
* Gollum, who murdered Déagol to get it, and later took it back from Frodo.
* Tom Bombadil, on whom it had no effect.
Two others handled the Ring but did not actually wear it: Déagol, who found it in the Gladden, and Gandalf, who held it only long enough to toss it in the fire. (In the movie, Gandalf avoids touching it at all, but in the book he does handle it very briefly.)
One interpretation of the Ring-bearer role, may be found in Peter Kjaerulff's The Ringbearer's Diary. Frodo's carrying the ring all the way back to Mt. Doom, symbolizes the task of carrying the weight of destructive emotions all the way to their origin. The ring symbolizes the central "knot" of the negative emotions.

The be@rbrick is my personal ring-bearer. He bears a ring, that reminds of my past. The ring has since tarnished. Poor bear. I did not want him to bear the pain alone. But...

"I would rather share one lifetime with you, than to face immotality alone"
Was watching "A Lot Of Rings" aka "The Lord of The Rings" with roomie when I heard this verse being said to the rightful King of Gandor, Aragorn by his secret lover, an Elf princess played by Liv Tyler (she's hot!!!)
