Copper sulphate is one of the most important industrial chemicals in use. Its extensive use in agriculture, health and medicine and various areas in industries call for continual production of this substance. This compound is prepared by the chemical reaction of sulphuric acid to a variety of cupric or copper (II) compounds like copper (II) oxide. Another way to prepare the substance is through the electrolysis of sulphuric acid with copper electrodes.

Copper sulphate has been used several thousand years ago. Ancient Egyptian civilization had discovered the purpose of copper sulphate in dyeing. This purpose has survived until today, more than five thousand years after its inception. The Greeks saw some of the medical uses of the bluish substance. It was used to treat some diseases of the lungs. Today a wide range of applications of copper sulphate can be seen in many fields. 1. Agricultural uses Copper sulphate, which commonly occurs in nature as copper sulphate pentahydrate, is one of the most important substances widely utilized in agriculture because of its fungicidal and pesticidal properties. It is mixed with lime to form Bordeaux mixture which controls fungal growth that may damage different crops. Perhaps one of the most important uses of copper sulphate is its fungicidal abilities. For instance, the application of cupric sulphate and ammonium carbonate prevents damping off in seedlings. Damping off is the rotting of young shoots of seedlings. Copper sulphate and other copper compounds control fungal diseases in apples, almonds, avocadoes, bananas, beans, barley, carrots, cherries, chrysanthemums, rice, roses, sunflowers, sweet potatoes, etc. It was in 1761 when the fungicidal properties of copper sulphate were discovered in agriculture. Farmers found out that seeds soaked in dilute solutions of copper sulphate were not infected with fungus. It has been practiced since then. The same thing was done to cereal seeds in the 1800s. The popular Bordeaux mixture came as a breakthrough sometime in the late 19th century when grapes, smeared with copper sulphate and lime to make them look distasteful, became free from downy mildew. That instance heralded the beginning of the application of copper sulphate in farming. Bordeaux mixture is composed of copper sulphate and lime. Another important mixture is the Burgundy mixture derived from the mentioned copper compound and sodium carbonate. Both are used to control fungus when properly applied at right amounts. Aside from fungicidal properties, the compound is also used to treat copper deficiency in soils. Soils with insufficient copper cannot supply plants well and animals grazing on copper deficient plants will in turn become copper deficient too. Altogether, these properties of copper sulphate and other copper compounds have become increasingly useful in farming and in livestock. 2. Health-related and medical uses The ability of cupric sulphate to kill fungi, bacteria, and parasites is not only confined in the fields of agriculture. This ability is used to keep algal blooms away from swimming pools and water reservoirs. Athlete’s foot can be controlled in tropical countries by including the substance in floor cleaning mixture. Copper sulphate also eradicates the snails that harbor the parasite that causes Schistosomiasis in humans. It kills mosquito larvae which causes malaria. In medicine it is used in the preparation of various pharmaceutical products. 3. Industrial uses Copper sulphate is an additive in adhesives. It is used to preserve timber and ward off wood worms and to avoid wood rot. In concrete, it serves both as a coloring ingredient and an antiseptic. It prevents mold growth in building materials. It keeps tree roots from growing in sewerage systems. It is a coloring agent for glass, cement, and ceramics. It has other various chemical uses – a catalyst, an electrolyte, and an ingredient in preparations of other chemicals. It is used in precipitation reactions and purification processes.

Women in South Africa advancing in fields of science and technology
August 21, 2020 · Uncategorized · (No comments)

Tuesday, August 25, 2009

Naledi Pandor, Minister of Science and Technology in South Africa, publicized results of a study on Tuesday on the role of women in the fields of science and technology in the country. Though women only make up thirty-three percent of publishing scientists in the country, their numbers have increased in recent years. When compared to a similar study from 2004, trends show increased enrollment of women in higher education.

Pandor was disappointed by the dearth of individuals that attended the announcement of the results of the study at the Parliament of South Africa. “It shows the degree to which science does – or doesn’t – matter to South Africans,” said Pandor. Prior to her role as Minister of Science and Technology, Pandor had served as Minister of Education of South Africa.

“It shows the degree to which science does – or doesn’t – matter to South Africans.”

Professor Anusuya Chinsamy-Turan, a woman scientist in South Africa, commented to News24 that some educational organizations in the country were “really, really hostile to women”.

Pandor highlighted problems affecting women and specifically black women in the country from increased participation in science, including “financial difficulties before and during tertiary studies, gender stereotyping, legacies of disadvantage in black communities, negative dynamics at workplaces, and the lack of attention to women’s specific needs”.

Women in the country are advancing against men in science fields, particularly engineering, agricultural studies and biology. At present there are a greater number of women than men among enrollments for degrees in higher education, and among individuals obtaining those degrees. According to The Times, “their biggest gain has been in health sciences, where women earned more than half the doctorates awarded in 2005”. Pandor emphasized a current need for additional women to enter the fields of technology and engineering.

The announcement at Parliament in South Africa was part of the launch of the “Facing the Facts 2009” booklet, which was published by a sub-committee of the National Advisory Council on Innovation (NACI), Science, Engineering and Technology for Women (SET4W). Dr. Romilla Maharaj of SET4W presented the report to Parliament, and stated that enrollment by women in higher education had increased by one percent from a previous study. Dr. Maharaj noted that women were still currently in the minority among individuals with degrees in higher education.

Baby in California born with 12 functioning fingers and toes, in a rare case of polydactylism
August 18, 2020 · Uncategorized · (No comments)

Tuesday, February 3, 2009

A six-pound infant born in San Francisco, California has six perfectly formed and functional fingers and toes on his hands and feet, so that it isn’t considered a disability or deformity, say doctors at Saint Luke’s Hospital who were amazed by the oddity.

In a medical rarity, super baby Kamani Hubbard was born two weeks ago with 24 working digits. He is healthy and home with his parents in Daly City, California. Polydactyly, a congenital disorder is not uncommon in humans and animals, including cats, but to happen on both hands and feet is a rare hereditary condition.

“Nurses and doctors, looked so normal they couldn’t tell, they told me he was six pounds in good health, that was all they said,” said Miryoki Gross, Hubbard’s mother. Her baby’s specialness didn’t even show up on prenatal ultrasounds. “I heard nothing before I gave birth so I’m still in shock, kinda,” Gross added. Despite the mother’s shock, Kamani’s father, Kris, was the first to notice the condition.

Polydactyly (from Ancient Greek means ‘?????’ (polus) or “many” + ‘????????’ (daktulos) “finger[s]”), also known as polydactylism, sexdactyly, hexadactyly, or hexadactylism, is a congenital physical disorder consisting of supernumerary fingers or toes.

In Kamani’s case, however, all of the digits are perfectly formed and function or work normally. “I was in amazement, it took a little time for me to take it all in,” said Kris, a postal worker, who has a family history of polydactylism, but none of his relatives can remember it happening on both hands and feet.

Mostly, cases of polydactyly are surgically corrected. Kris himself had nubs of sixth digits, which were removed during his early childhood, for having been non-functional. “My son has six fingers then I saw toes, and I thought, this is quite unique. Some family members have had six fingers, not completely developed. But not the toes,” Kris noted.

“I would be tempted to leave those fingers in place. I realize children would tease each other over the slightest things, and having extra digits on each hand is more than slight. But imagine what sort of a pianist a 12-fingered person would be imagine what sort of a flamenco guitarist, if nothing else think of their typing skills,” Dr. Treece remarked.

“I just want him to see what greatness will be in store for him,” said Kris.

Fully developed and functional extra digits on both hands and feet are considered very rare as a genetic trait in medical history, amid some partial development of an extra digit occurs about twice in every 1,000 white male births. Ordinarily, polydactylism appears as an extra piece of non-functional tissue, typically occurring as an extra finger, sometimes with a bone, but no joint.

“It’s merely an interesting and beautiful variation rather than a worrisome thing,” said Dr. Michael Treece, a St. Luke’s Hospital pediatrician, and the OBGYN who delivered Kamani. He has postaxial polydactyly, which is 10 times more likely to occur in black children, and also more likely to appear in boys.

Goliath, a figure in Old Testament, was depicted as having had six fingers on each hand and six toes on each foot.

Blues guitarist Hound Dog Taylor, Get Carter, Little Tich, Toyotomi Hideyoshi and several other figures in history have had polydactyly. Sid Wilson, a turntablist of Slipknot, had been born with an extra finger and toe on his hands and feet which were removed shortly after his birth as doctors considered them to be dead.

Four arrested in three Naperville, Illinois prostitution stings

Four arrested in three Naperville, Illinois prostitution stings
August 11, 2020 · Uncategorized · (No comments)

Monday, March 15, 2010

An undercover investigation by Naperville, Illinois law enforcement has led to the arrest last Thursday of four people allegedly involved in prostitution. The stings came after police received tips that people were using websites like Craigslist and Backpage.com to sell sexual performances in Naperville hotels. 

Patricia H. Scoleri of Naperville was arrested after an unidentified neighbor observed consistently suspicious activity at Scoleri’s home. Traffic was unusually heavy and consisted mostly of luxury cars in an otherwise quiet, middle-class neighborhood. Also, the visitors were mainly middle-aged men, and an odd string of lavender-colored lights were hung on the front window.

Police say Scoleri worked alone. She was arrested at 2 p.m. local time (2000 UTC) and is charged with violation of anti-prostitution laws, anti-cannabis laws, and the Massage Licensing Act. She apparently has four children, but the Illinois Department of Children and Family Services has neither contacted her nor received a police report on her.

The second sting occurred at 5:30 p.m the same day (2330 UTC) and resulted in the arrest of Chicago resident Tonya M. Adams. She is charged with prostitution and driving without a license. Another sting about an hour later resulted in the arrests of Jessica M. Walley, a Skokie resident, and Mark A. Williams, a self-admitted Schaumburg gang member. “Walley was charged with prostitution and unlawful possession of cannabis. Williams was charged with pimping, obstructing a peace officer, driving with a suspended license and driving without insurance,” reports WBBM News Radio 780.

All four suspects are free, having paid the required ten percent of their $1,000 bail. They may face additional charges related to crack cocaine discovered during the police investigation. Arraignment is scheduled for next month at the DuPage County Circuit Courthouse in Wheaton.

Dove ad viewed more than 3 million times on YouTube
August 9, 2020 · Uncategorized · (No comments)

Saturday, November 4, 2006

An advertisement for Dove beauty products has been viewed by well over three million people, without ever being on television. A copywriter from Ogilvy Toronto, the advertising agency that created a spot named “evolution”, uploaded the advertisement to video sharing website YouTube.

While the official upload of the ad itself has been viewed 1,119,262 times, there are dozens of copies of the ad on YouTube, adding to a minimum of 3,059,546 views. The official copy of the video is the website’s 12th most viewed this month, 53rd of all time.

Unofficial uploads have each received high levels of viewership, with 449595, 445322, 207906, 201670, 195265, 116501, and 102634 plays.

The agency did not originally intend to upload the video to YouTube, only display it on the company’s homepage. Staff member Tim Piper uploaded it to his account on October 6, about a week before it first got media coverage on Good Morning America.

The ad begins with a woman walking into a photo shoot. From there, she is primped and plucked by hair and makeup artists, then tweaked on a Photoshop-like program. The photo-manipulation is then posted on a billboard for the fictional “Easel Foundation Makeup” brand. Two young, teenage girls walk past, glancing at the board. “No wonder our perception of beauty is distorted” ends the ad in text, “Every girl deserves to feel beautiful just the way she is.”

The creative team for the ad included Tim Piper, Mike Kirkland, Janet Kestin, Nancy Vonk, directors T Piper (treatment and post production) and Yael Staav (live action) from Reginald Pike, Soho post production, Rogue editing, Vapor music, Gabor Jurina and Make-up: Diana Carreiro, and Reginald Pike.

The official French copy of the ad has only received 132 views, although it was only uploaded on November 2, 2006.

US Senator Rand Paul blocks synthetic marijuana legislation

US Senator Rand Paul blocks synthetic marijuana legislation
August 9, 2020 · Uncategorized · (No comments)

Friday, March 30, 2012

Senator Rand Paul of Kentucky is the lone holdout preventing a vote on synthetic marijuana legislation in the US Senate through a procedural block that is allowed under the rules. Until Paul lifts his block, the Senate will not be able to act on legislation that has already passed the US House of Representatives last December. Wikinews has investigated the block on the legislation.

Synthetic marijuana can be sold over the counter in some places and it is commonly known by brand names, such as “K2” or “Spice”. Other types of synthetic “designer” drugs, like “bath salts”, belong to a class of substances that are in some cases legal, though they create a health hazard, because they are declared not meant for human consumption.

At issue in the legislation is the amount of chemical substances banned, the criminalization of substances, the authority of the federal versus the state government to makes those decisions, the extent to which the product is a threat or hazard to public health and safety, and the effect such a law would have on the research of these substances. All of these issues were debated in the House. Paul has made an issue of the long prison sentences for marijuana. His critics claim he is going too far by blocking legislation. Paul, a Republican who has libertarian leanings, has argued that the states should have the authority to ban drugs.

According to the National Conference of State Legislatures, 31 states have a ban on both synthetic cannabinoids and substituted cathinones while 39 states have a ban on synthetic cannabinoids. Rand’s home state of Kentucky bans both. But legislation is not a perfect solution; in Cass County, Michigan, four teenagers between the ages of 13 and 14 had an emergency after using synthetic marijuana, but even though Michigan bans both, police are not sure that the substances are illegal. Chemists have to conduct tests on the products.

Although Paul is framing the issue as a legal one, the medical community has turned its attention to this new phenomenon’s impact on public health and safety. In an article that appeared in the March 2012 issue of Pediatriacs, medical researchers led by Dr. Joanna Cohen analyzed the cases of three teens who were hospitalized and treated as emergencies after an incident of synthetic marijuana use. One 16-year-old girl lost her motor skills and was unresponsive yet she had an exceptionally high heart rate and abnormal blood pressure. An 18-year-old boy was extremely sweaty, had a high heart rate and was agitated. And a 16-year-old boy had a speech dysfunction, as well as symptoms of agitation and confusion. The doctors who wrote the study say people are using this product because they believe it can give them a high similar to marijuana, however, the new drug can bring on both psychological symptoms, like psychosis and paranoia, and physical ones, such as convulsions.

One out of every nine high school students has reported use of synthetic marijuana, according to Monitoring the Future released in December 2011. The annual survey can be used to spot new trends in substance use among youth and the report included synthetic marijuana for the first time in 2011.

Poison centers noticed a sharp increase in calls reporting incidents due to synthetic marijuana. According to the American Association of Poison Control Centers, in 2010 centers nationwide took 2,906 calls for synthetic marijuana cases, but by 2011, they took 6,959 calls. The problem is noticeable to local health officials, like in Syracuse, New York, which is Senator Chuck Schumer’s state, where 120 cases were reported and one health professional called it “a significant public health concern.” New York has a ban on substituted cathinones but not synthetic canabanoids, according to the National Conference of State Legislatures.

Although the US Drug Enforcement Agency placed five substances that fall under synthetic marijuana into Schedule I on March 1, 2011, its emergency powers only last one and a half years and its ban has not stopped other substances from being used instead. Schedule I is a running list of banned chemicals.

… let us move forward with a vote

Three of Paul’s Senate senior colleagues say Paul should drop his block. Senators Chuck Grassley, Chuck Schumer, and Amy Klobuchar are sponsoring bipartisan legislation that aims to ban synthetic marijuana as a serious health threat. The legislation is bipartisan as Grassley is a Republican , while both Schumer and Klobuchar are Democrats. Senator Schumer, in an editorial for the New York Daily News, advocated tackling synthetic marijuana at the national level rather than at the state. Schumer’s argument is that states have tried to ban the ingredients commonly found these products but the manufacturers have the flexibility to alter the ingredients to bypass the law. Schumer said the federal government needs a proactive rather than a reactive stance against drugs. “All we need is one senator, Rand Paul of Kentucky, to release his block on this legislation,” wrote Schumer. “We’re urging him to do the right thing, and let us move forward with a vote.”

Before the Senate took up the issue, similar legislation had already passed in the House. The House voted 317–98 in favor of the Synthetic Drug Control Act of 2011 on December 8, 2011. Pennsylvania Congressperson Charles Dent sponsored the legislation that would add ingredients found in synthetic marijuana to Schedule I. Dent’s legislation included chemicals that are not even found in the United States at this time, but he argues that synthetic marijuana is too great of a public health threat to dismiss.

Standing in opposition to the legislation, Virginia Congressperson Bobby Scott and several fellow Democrats argued Dent’s legislation was bypassing a process for the banning of drugs that was already in place and established. Scott also argued some of the substances banned by the legislation were not even present in the United States but so far only in Europe. His colleagues argued researchers would lose the ability to conduct research freely on these substances and, as Scott noted, the legislation was seeking to ban substances but without any research to back it up.

Grassley’s legislation is named for David Rozga, an Iowan who committed suicide after using synthetic marijuana. In his speech, before the Senate, Grassley said Rozga’s situation inspired him to put forward the legislation.

For some families, the issue has also become an emotional one, as they have lost a loved one. Karen Dobner, a mother from Aurora, Illinois, is blaming Senator Paul for any deaths that may still occur because he is holding up a legislative solution to a problem that she says killed her own son. When her son Max was in college, he tried a synthetic marijuana product and had a panic attack. Dobner believes the car crash that killed her son would not have happened had he not been experiencing the symptoms of the designer drug. Now Dobner keeps calling Paul’s office begging him to stop his hold.

Senator Paul’s office was contacted by both phone and email about this report but it did not respond.

New studies may bring slug-made glues closer to use in medicine

In two studies presented on Monday at the annual meeting of the American Society for Biochemistry and Molecular Biology in Orlando, Florida in the United States, scientists have disclosed new steps toward using natural adhesives made by the dusky Arion slug (Arion subfuscus) in medical applications such as in closing skin wounds and reducing scarring.

When threatened, the dusky Arion slug secretes an unusual glue, making itself a difficult target for predators. This glue remains both sticky and flexible and works even when the surface the slug is on is wet. Previous studies have shown that, unlike many artificial adhesives, Arion slug glue is non-toxic to mammalian tissue.

Scientist Rebecca Falconer, an Ithaca College undergraduate who led one of the two studies, said “Typical sutures like staples and stitches often lead to scarring and create holes in the skin that could increase the chance of infection after surgery […] Understanding the roles of adhesive proteins in the slug glue would aid in the creation of a medical adhesive that can move and stretch yet still retain its strength and adhesiveness.”

In her set of experiments, Falconer observed eleven proteins found only in slug glue and used DNA recombination to produce usable amounts of each of these proteins. Specifically, she produced complementary DNA sequences (cDNA) for each protein, which are stretches of DNA with all the pieces not necessary for producing the protein removed. She then spliced these into circular DNA sequences called plasmids, which she inserted into bacteria, whose natural cellular machinery began to produce the proteins in quantity. She then analyzed the three-dimensional structures that the protein molecules form with each other and with other substances that make them work.

Christopher Gallego-Lazo, also an Ithaca undergrad, evaluated glue from the dusky Arion slug by focusing on the chemical bonds within the glue and the way they affect the glue’s deformability. Gallego-Lazo found that slight changes in these chemical bonds could alter the strength of the slug glue.

Gallego-Lazo said, “Few studies on biological adhesives have identified the exact nature of the bonds holding the glue together […] This knowledge can guide the development of an organic synthetic adhesive that would reduce the risk of infection and scarring compared to stitches and staples and could be applied rapidly and simply.”

Falconer and Gallego-Lazo both performed their research in the laboratory of Dr. Andrew Smith.
