Hydrated protons pair off

Saturday, February 16, 2008

Chemists modeling the structure of strongly acidic solutions have found that hydronium ions can associate into unusual ion pairs.

Hydronium ions form whenever an acid dissolves in water, but it had always been assumed that they would repel each other. This new work suggests that at certain concentrations a fraction of the hydronium ions can in fact pair up.

Gregory A. Voth and Sergei Izvekov of the University of Utah, in collaboration with Feng Wang of Boston University, were examining the structure of highly acidic solutions (pH 0 to 1) of hydrochloric acid using sophisticated computer modeling. It is known that in water such acids dissociate into positive ions (cations) and negative ions (anions), with the H+ part solvated by water molecules to form cations such as hydronium (H3O+). It might be expected that positive ions such as these would repel one another, but it turns out that some of these cations unexpectedly associate into pairs at acid concentrations of 0.43 – 0.85 M . The pairing disappears at even higher concentrations where larger aggregates of cations and anions instead begin to form. The authors note that “cation pairs are stabilized by a nonclassical charge delocalization of the excess proton charge defects over multiple water molecules”. They explain the phenomenon in terms of the amphiphilic nature of the hydronium ion discovered in their 2004 work.

Recent work by Wallace et al. indicated the presence of hydronium ion pairs in crystals, but this is the first time such an association has been predicted for an aqueous solution.

Chicago Gold Gallery is a jewelry buyer that Chicago trusts. The business has been buying gold, diamonds, jewelry and valuable pieces since 1980 and gained a reputation as an honest broker of antique and modern pieces alike. There is more value in many jewelry pieces than the current market value of the precious stone or minerals included in the piece. Like ancient coins, each piece has a value established through current trends in the market through sales and auctions of pieces from the same jewelry maker.

When selling jewelry, it is crucial that you receive the full value of your pieces. Jewelry from the Middle Ages or beyond carries a value that translates well beyond that of its weight in gold. The experienced jewelry buyers at Chicago Gold Gallery begin their estimate of the value of your piece by weighing the mineral and judging the quality of stones which establishes the base value of your jewelry. Then, they start adding value through the expertise of the artist who created your jewelry. At times, these artists are recent, in which case the value is determined by the current sales price minus the difference in resale costs.

Old jewelry has a value far beyond that of current trends. There are many ancient artists whose names lend value to the jewelry they produced. These are the pieces that require significant research to determine a price. Chicago Gold Gallery will not purchase your old jewelry without a thorough search of the market so that you get a quantifiable quote.

Bring your old jewelry to Chicago Gold Gallery for an offer that you can trust. If you cannot make it to the store at 1236 W. Devon Avenue in Chicago, then visit their website and fill out the forms to communicate with the jewelry buyers that Chicago trusts. Follow us on google+.

Canadian inspectors to test food ingredients from China

Saturday, April 28, 2007

The Canadian Food Inspection Agency (CFIA) has issued border alerts for specific protein ingredients, imported from China, that may be incorporated into products destined for human consumption.

Inspectors from the Canada Border Services Agency (CBSA) will hold products, such as wheat and corn gluten, as well as soy and rice proteins until they can be tested for melamine, the contaminant found to have sickened pets through its use in pet food. If determined to be free of melamine, the ingredients will be released to the intended recipient. Materials such as glutens and protein powders are used commonly in many forms of food products.

The CFIA said it was not acting on specific information, but rather taking a cautious approach to human protection. “That’s why we have the border lookout for the ingredient, so that we can proactively assess any potential that the product is contaminated,” Paul Mayers of the CFIA told CBC News.

Since the border alert for melamine is a new procedure, the government can’t be sure if the contaminant made it into the food chain previously. The CFIA acknowledged that the same Chinese company under suspicion in the tainted pet food affair had shipped wheat gluten to a Canadian company, which in turn used it in food for fish farms. Although the fish were subsequently eaten by people, the CFIA believes the health risk from such consumption would be low.

In related news, Canadian researchers at the University of Guelph believe they may have determined the mechanism of how melamine caused illness in cats and dogs.

Both cyanuric acid and melamine were found in urine samples from pets that died after consuming contaminated pet food. The two compounds react with one another to form crystals that may block kidney function, researchers at the university said. The researchers observed crystals formed in cat urine by the addition of melamine and cyanuric acid. The composition of these crystals matches those found in the urine of affected pets when compared by infrared spectroscopy (FTIR).

“You wouldn’t normally expect to find those compounds in pet food, and hence nobody was really looking for it,” said John Melichercik, director of analytical laboratory services. “It’s just another piece of the puzzle along the way in this particular pet-food issue.”

Koreas hold joint training session for Olympics

Tuesday, January 30, 2018

On Sunday, female ice hockey players from North and South Korea joined one another for a training session before the upcoming Winter Olympics. Players from the two Koreas are to compete together as a united team for the events hosted in Pyeongchang, South Korea, which are scheduled to start on February 9; Seoul’s Unification Ministry said. The cross-border gesture is part of diplomatic efforts to ease tensions on the divided Korean Peninsula and the team was approved by the International Olympic Committee.

The International Olympic Committee selected Pyeongchang in 2011 to host the event, marking South Korea’s first opportunity since the 1988 Summer Olympics in Seoul. The earlier event was marred by violence as North Korea had bombed a South Korean flight several months prior, killing over 100 and boycotted the event. Inter-Korean relations have changed considerably in the ensuing thirty years, including the two sending unified teams for table tennis and youth football in other non-Olympic competitions.

The announcement that the two countries would compete together was a stated goal of South Korean President Moon Jae-in. Last year, he announced the proposal and the two nations went into discussion this month. After two weeks, they made the announcement to field a consolidated 35-strong team of ice hockey players and have joint skiing exercises with both team coaches involved.

According to Yonhap News Agency estimates, about 80% of South Koreans support dialogue, but the move to have a joint team has been controversial. Over 10,000 South Korean citizens sent a petition to South Korean President Moon opposing the union and a group of North Korean defectors held a protest at the South Korean National Assembly on January 24, tearing apart photos of the North Korean leader, Kim Jong-un. Public support for eventual reunification of the Korean peninsula has waned in recent years, with the younger generation more skeptical of the possibility.

Google’s YouTube to present its best video awards

Monday, March 19, 2007

This week Google’s on-line video sharing website YouTube launches its own awards ceremony. The site will present the best user-generated videos posted during 2006 in seven categories. The starting point is Monday and users will end voting on Friday. Winners will get their trophies on March 26.

The categories that YouTube is going to present include: most creative or inspirational video, best series, as well as music video or commentary and best comedy. The last category, number seven, is called “most adorable video ever” and it is to continue the tradition of videos starring cats and dogs while asleep.

Those that are nominated are able to promote themselves on YouTube during the following five days. These users are also able to plead for votes.

The $1.65 billion Google’s acquisition gathered a huge number of fans. According to Jamie Byrne, head of YouTube product marketing, 2006 was a pioneering year for sites that rely on user’s content.

However, companies like Viacom, believe one category is missing – “Best Professionally Produced Copyrighted Video.” Last week Viacom sued Google together with YouTube for more than $1 billion. The lawsuit states that the ever increasing popularity of YouTube is due to a massive uploads of copyrighted videos including “The Colbert Report” and “South Park“.

Six miners trapped in Utah mine after possible earthquake

Monday, August 6, 2007

At least six miners are trapped approximately 1700 feet underground in a coal mine in Utah after portions of the shaft collapsed. The mine is owned by Utah American Energy and is close to the town of Huntington, Emery County, 160 km south of Salt Lake City.

Robert Murray, The CEO, President, Director and owner of Murray Energy and the owner of Utah American Energy, said during a press conference at 5:00 p.m. (eastern time), an “earthquake caused the collapse at about 3:00 a.m. (mountain time).”

The United States Geological Survey (USGS) recorded what is allegedly a magnitude 3.9 earthquake at 2:48 a.m. (mountain time) on Monday morning 21 km (13 miles) east, southeast of Mount Pleasant, Utah, but the director of the USGS seismology stations Walter Arabasz, says that no earthquake caused the collapse.

Murray states that at least “two mining machines will be brought in to clean out the debris” at the beginning of the collapse and that he will “spare no expense” in rescuing the men.

“We have four rescue teams working to free the trapped miners. We will try four ways to get to the miners which include drilling 1,700 feet from the top of the mountain. We will also drill a hole” in a neighboring mine shaft sealed in 2004 after it was finished being mined that is “about 100 feet from the miners.”

Manitoba volunteers go to war against Red River flooding

Monday, April 6, 2009

Over 1,600 volunteers registered to help build approximately 65,000 of the 500,000 sandbags to create dikes 20.5 feet (6.2 meters) high to protect the City of Winnipeg, Manitoba in the war against the Red River of the North flood.

700 volunteers answered at the rural municipality of St. Andrews alone. Once sandbags are filled for West St. Paul, St. Andrews, and Selkirk, then frozen culverts must be cleared.

The height of the river is expected to be Thursday, and predictions are that it will be less than Flood of the Century of 1997. There is no precipitation in the forecast, and snow in the province should be melted by the end of the week.

“The fear right now is we have to get that ice out of the river. The Amphibex [Excavators] are still working and breaking the ice apart, and everyday we buy with the warm weather and the current, it is thinning the ice down a bit, so when it does start to move, the better chance it’ll move right out into the lake,” said Paul Guyder, the emergency coordinator for the RMs of St. Andrews and St. Clements.

“I feel that we’ve done everything humanly possible to get ready,” said Gary Doer, Premier of Manitoba, “But … there are fallibilities with human behaviour. We can take every preventative measure as human beings possible and we can still get Mother Nature proving again she is superior.”

Communities with ring diking will partially or fully close their dikes at the beginning of the week. Provincial officials are considering opening the Red River Floodway gates around mid-week before ice is fully melted.

Ice jams could cause flooding within the city, however opening the gates could spare neighbourhood flooding when the river rises to the estimated 6.3 meters (20.7 feet) height. The province does have back up plans for dealing with ice jams within the city if they do occur. The unpredictability of ice jams and the ensuing water level rise may cause neighbourhood flooding. The city is raising dikes where the river has jammed with ice in the past such as on tight curves and past bridges. Likewise there are excavators and backhoes positioned at these points.

Vulnerable neighbourhoods on the river banks have been reinforced with sandbag dikes at vulnerable areas from the massive volunteer effort over the weekend. Guyader feels no more extra volunteers are needed, however volunteers are still being asked to leave their names and number in case of unpredicted need. Existing personnel will assess roads, and help with clean up.

Approximately 400 of the 800 people who evacuated the Roseau River Anishinabe First Nation have returned to their homes.

Former Premier, Dufferin Roblin, brought forward the floodway as a protection for Winnipeg residents and economy following the 1950 Red River Flood. The Red River floodway, “Duff’s Ditch” was finally finished in 1968, and its floodway gates have been opened 20 times saving Winnipeg from an estimated CA$10 billion in damages. The floodway expansion began in 2005 at a price of $665 million.

Polish and Chinese experts have come to survey the Red River Floodway, and Dennis Walaker, mayor of Fargo, North Dakota recognises the need for Red River flood defences down river. “Every town that you drive by from the Canadian line up to Winnipeg is either elevated or ring-diked,” said Walaker.

“No H5N1 virus” found in blood tests of suspected human Bird Flu cluster

Thursday, August 3, 2006

Preliminary tests performed on samples taken from six villagers in the Kabanjahe District of Sumatra in Indonesia have tested negative for the deadly H5N1 Avian Flu virus.

“Investigations by the ministry of health lab and Namru, too, on August 2 and 3 on all specimens collected from the suspected cases in Kabanjahe district came up negative,” said Indonesia’s health minister, Siti Fadilah Supari.

Final test results are expected in at least seven days from the Center for Disease Control (CDC) in Atlanta, Georgia. “The World Health Organization (WHO) requires human samples to be sent to one of WHO’s six collaborative centres. So, we only need to send them to CDC Atlanta as it has worked with the U.S. NAMRU-2 lab here,” added Supari.

Supari also stated that all individuals are suffering from the “common flu.”

Saturn Journeying Through Libra

Click Here For More Specific Information On:

By Meg Sweet

Timeframe:Oct 30, 2009 – Apr 7, 2010 and July 22, 2010 – Oct 5, 2012

The astrological sign of Saturn will be journeying through the Air sign of Libra during the above timeframes. Astrology has a traditional system of classifying how planets operate within each sign, and Saturn in Libra is said to be in an ‘exalted’ position, or coming from the highest possible expression.

Representing, among other things, the practicalities and responsibilities of life on the physical plane, and whether or not we care to be conscious of the movements of Saturn or not, we are clearly drawn to, and influenced by those areas of life which Saturn addresses as it transits through a specific sign.

The transit of Saturn through Libra will bring our collective attention to the following arenas:

Relationships

The relationship oriented sign of Libra, ruled by Venus, has as strong desire to establish balance, harmony, respect, fairness, peace and cooperation within all relationships. Libra believes in expressing high principles and integrity in relationships and seeks to bring people together to welcome them to be in relationship and celebrate life. This socially outgoing sign places a high value on marriage, partnership and collaborative efforts between parties.

Personal attributes associated with this sign include charm and grace, a love of beauty and the arts, refinement and a good eye for fashion and design, intellectual and artistic expression and an intricate awareness of the subtleties at work in human relationships.

Individual Relationships

By the nature of Saturn in the relationship oriented sign, we will be drawn to investigate our relationships up close and personal to determine where the relationship is at and where we’re going with it. For those not involved in a committed relationship and who want to be, you’ll likely feel the pull to step up your search for a partner.

With regard to personal relationships and partnership, Saturn in Libra asks the following questions of us:

1) What is our understanding & experience with intimate relationships

2) How are we operating within our current relationships 3) What is our responsibility toward others in our relationships 4) What do we expect of others and want them to do for us 5) How can we improve our relationships 6) Is there an opportunity for growth in our current relationships

Relationship to Society

Saturn in Libra reflects a keen interest in moral obligation, social responsibility, the study of and implementation of justice, with particular interest in the relationship between individuals to their society and vice-versa. This combination suggests that there should be a mutual responsibility between the individual contributing in some way toward strengthening and supporting those elements of society which he/she has an affinity with and in return, society should also respect, honor and protect individual rights.

Saturn in Libra brings us to the realization that to accomplish anything of lasting value, cooperation between humans is necessary and, if we are to commit to building relationship and community, we must also build in trust, respect and a willingness to accept diversity.

This combination is well suited to the formulation of legal contracts, agreements and the writing and implementing of new laws which are in part focused on offering and protecting the needs and the rights of the individual.

Intellectual and Creative Expression

Saturn in Libra energies help to strengthen and expand our intellectual abilities so that we can creatively express and articulate our thoughts, which is why this combination is well suited to the pursuit of studying and learning. Saturn and Libra energies work together to promote objectivity, receptivity and order in our thinking process, as well as balance, diplomacy and a splash of artistic flair and savvy. This makes for excellent timing to write that first play, take on your first public relations client, facilitate a group on relationships or get your first blog or website up and running.

The sign of Libra supports the idea of the sharing of information, knowledge, resources, wisdom and hands-on expertise, which is why many individuals with a strong Libra influence, make such good advisors, mediators, counselors, coaches and mentors. This is a beneficial time to commit to a course of study, training or mentoring preferably in a one-on-one situation or within a small group.

A great way to approach the transits of Saturn throughout each sign is to ask ourselves how we can make Saturn work to our benefit. To do this, we need to become informed about the specific areas which are addressed by the transit.

As an example, Saturn in Libra, in reference to intellectual capabilities and creative expression, lends itself to optimizing and strengthening our mind power. There are so many ways in which we can use our mind power.

When we teach the mind to be quiet and turn within, we can meditate, a practice which helps us feel mentally recharged, deeply rested, centered within ourselves and spiritually connected.

When we want to learn something new mentally, or pursue a course of study, we can focus the mind and use the patience, objectivity and intelligence associated with this placement to apply ourselves to the task at hand.

When we’ve learned how to focus our thoughts, we can practice intention. By holding steady and consistent energy in a specific group of thoughts, with a deliberate intention in mind, we can create an intense laser beam of focus. This practice can bring about powerful results.

If we want to learn about creative visualization, we can use the power of our imagination to create images or movies. Since we are directing our own movie, we can select which images and experiences we want in there and select the feelings we also want to experience. This gives a powerful message to the subconscious and is a good practice to use for attracting what we desire.

The sign of Libra is ruled by the planet Venus, Patroness of the Arts, so creative expression and an interest in the Arts is also stimulated and supported by this transit.
