Schematic diagram of an EDI module |
An important application for electrodeionization is the production of pure water and ultrapure water. In EDI, the purifying compartments and sometimes the concentrating compartments of the electrodialysis stack are filled with ion-exchange resin. When fed with low TDS feed (e.g., feed purified by RO), the product can r... |
Each cell consists of an electrode and an electrolyte with ions that undergo either oxidation or reduction. An electrolyte is a substance containing free ions that behaves as an electrically conductive medium. Because they generally consist of ions in solution, electrolytes are also known as ionic solutions, but molten... |
Water is passed between an anode (positive electrode) and a cathode (negative electrode). Ion-selective membranes allow the positive ions to separate from the water toward the negative electrode and the negative ions toward the positive electrode. High purity deionized water results. |

Hundreds take an icy plunge for a good cause |
Posted: Updated: |
By: Kayla Bremer |
A big crowd turned out to watch hundreds of people submerge themselves in the freezing water to raise money for the Special Olympics. |
"Freezin' for a Reason" is the motto for the Polar Plunge. It's the 8th year of the event and with snow on the ground and temperatures in the low 20s, dozens of groups of people plunged into the icy waters of Holmes Lake. |
"Very cold," Polar Plunger Ashley Weyers said. "Very cold, you don't breathe. Your heart stops." |
Volunteers ranging from little kids to a 92–year–old man turned out in style and jumped in the lake. |
One group, made up of teachers has made the plunge the last five years and this time around, raised more than 500 dollars for the cause. |
They say the plunge is something they plan on doing every year. |
"We just think it's a great cause," Jen Birdsall said. "Especially the Special Olympics and so we thought, why not jump in a lake and let people pay us." |
The event is held in five different Nebraska cities to raise awareness and money. |
President and CEO, Carolyn Chamberlin, says this is an event that continues to grow and this year's goal is to raise 200–thousand dollars from all five plunges. |
"It's a little crazy," Chamberlin said. "But second of all, I think it's a very exciting opportunity to do something that you might not normally do." |
Costumes, like Scooby-Doo and the Blue Man Group, were a big thing among the volunteers braving the cold water. |
Groups of students, co–workers, family members and teammates dressed to impress for the icy swim. |
"It's breath–taking," Kerry Zingg said. "I mean it just kind of takes your breath away. Each year, you wonder why you do it again." |
The final numbers are in from the Lincoln plunge...39 teams adding up to 220 people made the jump into the lake raising a total of 35–thousand dollars. |

Do veterans have a right to free health care for life? |
The law provides free medical care for servicemembers on active duty and their families, Graves said in an email. |
Congressional Research Service, which provides analysis for Congress, issued a 2003 report that found veterans were not entitled to free medical care for life, even though they may have been promised exactly that by their recruiters. |
Since 1956, veterans and their families can be treated at military medical facilities "subject to the availability of space and facilities and the capabilities of the medical and dental staff," the report found. |
"They have no right to military health care and the military services have total discretion in when and under what circumstances retirees and their dependents will get care in military treatment facilities," the report said. |
Several veterans have taken their claims to court, alleging that recruiters promised them free medical care, but one court ruled that such promises did not constitute a contract, the report said. |
Moreover, since recruiters do not have the authority to make such promises, there is no way to enforce them, the U.S. Court of Appeals for the Federal Circuit ruled in 2002. The Supreme Court later refused to hear the case, ending the matter. |
"The courts, and other analysts, have noted that allowing these claims to create such an obligation would thwart the Constitutional role of Congress (i.e., prevent the Congress from determining the compensation and benefits of the armed forces) and create a situation wherein military personnel/retirees (and potentially... |

When should I use require_once vs include? |
There are many answers and counter questions I some times feel I'm reading someone else's chat messages. |
The creators of this site have great intentions but some users have only wrong intentions –just increase some reputation–yes I meant it. I have seen so many answers here which are just plain rip offs of someone else's answers in the same thread. |
Unless you guys do something like highlighting the answers with the most upvotes or something (I saw the tick, but noobs don't even notice it, I'm afraid). |
Just hoping this site won't become uninteresting for new users. |

Are you sorting answers correctly? If you sort by votes, the highest-voted answer will rise to the top. – The Grinch May 23 '12 at 4:19 |

Stack Exchange works, in part, based on the idea of crowdsourcing: you ask a question of a large, diverse population that provides you with a number of individual answers, and ostensibly the responses will converge on an answer that solves the problem you have. |
To that end, it's essential Stack Exchange provides the opportunity for (mostly) anyone to answer a question at any time: there's no way to know beforehand whether the first answer is correct or whether some guy, 4 years from now, just happens upon the question and provides the best answer ever. |
The end result is that questions will generally have multiple answers: that's good for everyone, as bad or non-optimal answers get replaced with better ones over time. The community converges on the best possible answer by voting: the answers the community and the asker generally consider to be correct right now will b... |
If you're in a hurry or confused and did nothing but look at the top answer you're very likely going to be fine. If the top answer is wrong or doesn't help, that's what the other answers are for: if they didn't exist, there'd be no alternative to an answer that's wrong but happened to get there first. |
There may be some merit to making the top answer more prominent, but it's already pretty prominent by virtue of being first (and very likely above the fold). |
Note 1: unless the question asker accepts his or her own answer, due to conflict of interest |

@jathin I assure you, having multiple answers on a question does not significantly slow down the site. Again, you don't need to look at any of those extra answers if you don't want to: the one vetted by the community and the asker is always at the top. Stack Exchange is constantly updated and the answers provided are c... |
Hi Mine was just a suggestion . I didn't say you must limit the answers. By this "Unless you guys do something like highlighting the answers with the most up votes or something ", I actually meant some highlighting of background, see some new users don't even notice the tick mark(the inactive white one--until the answe... |
@jathin After a total about three or four downvotes, it will turn grey. Also, unless you changed it, the order is: 1.) The one with a bounty (if there is one), 2.) Accepted answer (again, if there is one), and 3.) the rest of the answers, sorted from the highest score to the lowest. We already do what you're trying to ... |

Before I knew that school buses were yellow, I experienced them as tangerine. I argued with my betters about this. If a good part of education is training the judgment to accept the consensus view, then I was educated to understand what adults were convinced of: that school buses are yellow in the same way roses are re... |

Denise Levertov’s poetic communion with the world. |
Alma Deutscher might sympathize. From the time she began speaking, she was the subject of a linguistic experiment: her father refrained from associating "sky" and "blue" to see if she would spontaneously put them together—a natural equation, like two and two making four. It didn't happen, so eventually her father start... |
and even then it had not yet become canonically blue: one day she said "blue," another day "white."… In short, more than six months had passed from when she was first able to recognize blue objects confidently until she named the blueness of the sky. And it seems that her confusions were not entirely over even by the a... |
Had Alma seen that the sky is blue the way school buses are yellow and roses are red, she might not have given her father, Guy Deutscher, a linguist at the University of Manchester, further proof of what he suspected: that the cultural nuances of our mother tongue influence our perceptions and possibly whole structures... |
This is a hypothesis that seems intuitively correct, but it is one that has had to fight its way back from intellectual ignominy. In 1936 Benjamin Lee Whorf published An American Indian Model of the Universe, which asserted that "the Hopi language is seen to contain no words, grammatical forms, constructions, or expres... |
That Deutscher should rest the bulk of his argument for linguistic relativity on research into color perception seems partly poetic, partly whimsical. But he unearths an unlikely string of stories showing this research stretching back further than we might think. In 1858 the future prime minister of Great Britain Willi... |
The Greeks, Gladstone concluded, were color-blind. While his peers heaped ridicule on his theory, another linguist, Lazarus Geiger, launched his own study based on Gladstone's conclusions, widening the scope to include color epithets in the Old Testament, the Indian Vedas, Icelandic sagas and the Koran. These ancient w... |
Color isn't Deutscher's only example of linguistic relativity; he lays out the effects that feminine and masculine nouns have on the perception of objects by native speakers of gendered languages. He describes the outstanding "perfect pitch for directions" exhibited by the aboriginal Guugu Yimithirr tribe, whose langua... |
The poetic obsession with color has distinctly quotidian uses. In 1875 a train wreck in Lagerlunda, Sweden, gave the scientist Frithiof Holmgren the opportunity to test his theories on the anatomy of vision, which were inspired by the work of Gladstone and Geiger. Despite protestations by railway authorities, Holmgren ... |

Improvement agenda for CBI: Investigation and prosecution must be done independently, as in the US and UK |
ET Bureau May 5, 2012, 04.20AM IST |
By Satya N Mohanty |
CBI is expected to be in the frontline of war against corruption, particularly for deterrence of the same. But the institution requires overhauling, the law requires amendments and the approach requires refashioning to reverse the prevalent perception as well as experience. |
A general perception of selectivity, politically-pushed agenda, below-par investigation that results in large-scale dismissal of cases and the pyrrhic effectiveness where result is manifested in prosecution and arrest rather than truly bringing the culprits to book is the nub of the matter. With enormous expectation fr... |
Arrest, imprisonment and prosecution could be like 'vigilante justice' ahead of final findings. But they are not likely to have sustainable impact on the systems and the society when prosecution fails, decoupled from initial flash work associated with seemingly quick retribution. But the litmus test is whether the inve... |
Amendments to Prevention of Corruption Act that were incorporated in 1988 provide several presumptions of corruption. With these presumptions provided by the law, both sloppy investigation on one hand and high-handedness of the agency on the other are very much plausible. They are: |
If a decision of a public servant benefits a person without public interest, he can be prosecuted even if he has acted in good faith. In government, every commercial decision helps one party or the other. The unintended consequence of positive and negative externality cannot be dubbed as corruption without mens rea bei... |
If a public servant is in possession of property that is disproportionate to 'known source of income', he can be prosecuted. The problem is the expedient and creative definition of 'known source of income' that includes income from lawful source but has not been intimated in accordance with the 'provisions of any law, ... |
While sanction of the employer is necessary for prosecution of a public servant by qualifying it as 'who is employed', it means no sanction of the employer is necessary the moment the public servant retires. |
The aborted attempt at amendments to these clauses in 2008 that got the approval of Rajya Sabha and was awaiting approval of Lok Sabha when the Lok Sabha got dissolved, needs attention again. The problem is both arrest and prosecution can be done with impunity that have a semblance of right action and result while they... |
Agencies like CBI develop institutional culture and institutional strategies of their own. Draconian provisions help the agents in capturing the process. They develop their own style, approach and method though not being in consonance with the objective and being violative of legal principles. It is finally the princip... |
For issues like white-collar crimes including corruption with vanishing trail, a multidisciplinary team consisting of people trained in law, taxation, chartered accountancy and police are required. |
Now limited to policemen, often the investigation is considered far below the desired quality required, but prosecution is launched nevertheless. Among several ways of achieving the same goal, people gravitate to the least-demanding course of action, that is, charge-sheeting in the instant case. Just accepting that the... |
When a case goes to the special court, the judge is more likely to give conviction order with minimum acceptable level of evidence, even though he knows about gaping holes in evidence as the price involved in acquittal can be high in terms of his reputation. Cases go on appeal and very often fail there. |
