Squid By-product Gelatin Polymer as an Eco-friendly Corrosion Inhibitor for Carbon Steel in 0.5 M H2SO4 Solution: Experimental, Theoretical, and Monte Carlo Simulation Studies
- 12 Downloads
A squid by-product (SBP) gelatinous protein polymer has been extracted, characterized, and examined as eco-friendly inhibitor for carbon steel in 0.5 M H2SO4 media by weight loss and electrochemical techniques. It was found that the SBP acts as a good corrosion inhibitor. The inhibition efficiency increases with increasing inhibitor concentration, but the temperature has hardly affected on the inhibition efficiency of SBP. Thermodynamic data clearly show that the adsorption mechanism of SBP on the carbon steel surface in 0.5 M H2SO4 solution is mainly physical adsorption. Moreover, the adsorption of the SBP molecules was found to follow a Langmuir adsorption isotherm. Results of potentiodynamic polarization measurements revealed that the SBP acts as mixed-type inhibitor. Data obtained from electrochemical impedance spectroscopy studies were analyzed to model inhibition process through appropriate equivalent circuit model. Theoretical parameters derived from quantum chemical calculations as well as binding energy derived from molecular dynamics simulation studies adequately corroborate the trend of experimental inhibition efficiencies of the studied inhibitors.

http://www.cbc.ca/m/news/canada/montreal/toys-r-us-in-quebec-refuses-to-sell-english-only-daniel-tiger-doll-1.3031253 Toys "R" Us in Quebec refuses to sell English-only Daniel Tiger doll Montreal father says it should be up to parents, not province to determine what toys kids play with Apr 13, 2015 8:13 PM ET Kate McKenna, CBC News A Montreal man is criticizing Quebec language laws after trying to buy a toy from a local Toys "R" Us — and being told by a clerk he wasn't allowed to purchase it. Chez Geeks board-game store gets OQLF complaint Quebec government stance dismays francophone school supporters Looking back at 40 years of French as Quebec's official language Blue Dog Motel bar no longer in hot water with OQLF Nick Messina tried to purchase a "Daniel Tiger" plush toy for his infant daughter Carina after noticing her eyes "lit up" while watching the popular children's TV show Daniel Tiger's Neighbourhood. Hoping to buy it as an Easter gift, he drove to his nearest Toys "R" Us, which didn't have the toy in stock. Then he called another Toys "R" Us in Montreal where clerk informed Messina there were two of the toys in stock. However, the clerk told Messina that he couldn't buy a Daniel Tiger because the toy is unilingual. "It's kind of saddening."- Nick Messina, father Daniel Tiger talks and sings 14 different phrases — but they're all in English. Messina said the clerk thanked him for letting them know the toy only spoke English, and said it would be shipped back to Ontario. "I kind of felt a little bit turned off. I felt it was discriminatory against the English-speaking community in Montreal. After all, Montreal is multi-ethnic, multi-cultural," he said. Not giving up, the father tried to purchase the doll online — only to discover the Toys "R" Us website wouldn't ship the product to Quebec. English-speaking toys illegal Messina didn't know until a few weeks ago, but because of Quebec's language laws, it's illegal to sell a unilingual toy unless the toy has a French-speaking counterpart. He says it should be up to parents to decide what toys they can buy for their kids, not the province. "I don't understand why, when it comes to the choice of purchasing a toy for our children, that we have to be subjected to these kinds of rules and regulations," he said. "It's kind of saddening." Toys "R" Us admits mistake In a statement to CBC News, a spokeswoman from Toys "R" Us apologized for the inconvenience, but said the toy shouldn't have been on the shelves. "Toys 'R' Us shipped in error the English-speaking product to one of our Quebec stores and a customer tried to purchase it. Our store did not sell the product to the customer and we apologized for the inconvenience that this caused our customer. We immediately communicated to our store that this product cannot be sold," said the statement. Happy ending for family Messina's perseverance paid off. He did manage to buy the doll eventually; he bought it on Amazon for about $50 more than what Toys "R" Us was asking. Though it was more than he planned to pay for the doll, Carina adores her new toy. For Carina Messina, it was love at first sight for this Daniel Tiger doll. (CBC) sent via Tapatalk

The way we perceive ourselves is completely different to the way others see us. What we see in others is also our own personal point of view – this does not mean we are right nor wrong, but it is nothing but an opinion and opinions do not hold truth.
When I had my surgery at 17, the body issues of a teenage girl had amplified tenfold to say the least. I couldn't bare the sight of myself in the mirror at times as all I saw was sickness, pain, misery and a disability. In due time I found my confidence again and would wear a bikini on the beach with friends looking confident on the outside but on the inside I was uncertain, unsure and at times afraid.
I was afraid of what others were thinking when they noticed I had a stoma cap on. Would they notice at all? Is it all in my head? What do I do if someone comes up to me? These, and many more are all the questions that went through my mind and I am sure that similar questions go through your mind when you go to the beach whether you have a illness or not. Body issues and body shaming are so apparent in society that it has almost become the social norm to scrutinize ourselves and one another.
Throw into the mix the lifestyle and industry I am a part of today – bodybuilding. The most vain sport you could ever be a part of and can damage even the strongest willed people from the inside out. We are judged on our bodies – our legs are too big, shoulders not wide or defined enough and perhaps our waist isn't small enough. It's a sport based on proportion, symmetry, presentation and aesthetics.
Too often as of late I've seen and heard, not only everyday people, but celebrities and bodybuilders body-shaming themselves and each other. Quite frankly I am absolutely sick of it. There's nothing that gets under my skin more than seeing someone putting others down because they feel they have put on weight or they don't have a nice body – which is all a matter of opinion. Who are we to judge someone else based on their body? A body that is the only one they have to live in and if that person is happy in their skin or they are on their own journey to making themselves better then it's nobodies place to speak or offer opinion.
As soon as you open your mouth and make comment you are opening yourself up for criticism of not only you as a person but your body as well – let's face it, nobody likes being criticized for the way they look!
We live in a world where our imperfections seem to gain more attention than our perfections. We would rather pick at the things we don't like about ourselves instead of the things we do like.
Let's amplify and acknowledge the things we like and work individually on the things we don't.
There's no need for bitter squabble or to use your voice in a way that shames others.
Everybody has a body unique to them – large, small, in-between, muscular, shredded and off-season.

text: Mr Carl Mincher - Weekly Update: 27/05/16 27 May 2016 Dear Parents, If you are feeling in need of a pick me up, a reminder that the theatre production of George's Marvellous Medicine is on this weekend, details below. It promises to be a great show! Headteacher's Information Evening We held a Headteacher's Information Evening this week and I was delighted to see so many parents. Discussion centred around the key features of the IB and IGCSE curriculum. All parents have received the presentation by email. The many and varied ideas that we generated together during the evening and in the our following correspondence have been particularly useful. The information evening will be held once each term and focuses on areas of interest to parents. If you have any suggestions around topics of interest then please do contact me. Assembly On Monday, the Head Prefect Team, Haeon Yoon, Steven Vo, Saanya Mishra, & Steve Ko, had an opportunity to present an assembly on Student Led Extra Curricular Activities (ECA's) in AP2. Through interviewing a few established ECAs in the school such as Model United Nations, Dumbledore's Army, Project Impact and Atramento, they were able to convey students' passion for a wide range of extra curricular interests. Common to each of these ECAs was the fact that the activity had been suggested, planned and organized under student leadership. Overall, it was a great chance for the team to share their thoughts on leadership, and we hope that not only will these student initiatives continue to develop in the future, but new student led activities will also emerge during the next academic year. All of our assemblies begin and end with student musical performances, this week Avinie Pham from Year 10 welcomed us with an excellent rendition of 'Misty' by Erroll Garner. Environmentally friendly teachers During last week's Environmental Awareness Week, the Year 7 students were keeping a close eye on their teachers to see who was setting a good environmental example. Each group nominated a teacher and provided reasoning for their choice including always having the blinds open and lights off, using recycled paper wherever possible, having the room at a normal temperature and switching the interactive board off when it is not being used. The most environmentally conscious teachers were voted as: Mr Fortune (7C), Mr Whiteley (7B), Mr Roberts (7B), Mrs Husband (7H), Ms Fish (7S), Mr Lewis (7N), Mrs Deleporte (7V) and Mr O'Neill (7I). Each teacher was rewarded with recognition amongst the rest of the staff by Mr Durrant and received a bar of ethically produced Marou chocolate. Well done again to Year 7 for their efforts in raising environmental awareness and setting a good example to the rest of the school. Photo: Ms Deleporte receiving her bar of chocolate from Camilla and Nha Trang Year 7 Primary FOBISIA Games Last weekend BIS HCMC was delighted to host the Primary FOBISIA games. Please do take a look at the photos available here. Making full use of the Primary and Secondary facilities, as well as outside sport venues, meant that the Primary and Secondary PE Staff were all fully involved. A number of our Secondary students helped out on Friday and Saturday. Thank you to all those involved for an fantastic, well run event. A special mention from the PE department must go to Jacob Gleave, 10S, who went above and beyond all expectations, staying for an extra day and using his own initiative to help out when needed and going way beyond the role he was given. The Kagools This week BIS has welcomed comedy duo Wilkinson Ford into the Drama department. Nicola Wilkinson and Claire Ford are professional actors who have been touring Australia with their show The Kagools. We were delighted to have Nicola and Claire host drama workshops with our Year 10 and 12 students. BIS Inaugural Concerto Competition Winner Congratulation to Celestine Koh, 10V, who was selected as the winner of the BIS Inaugural Concerto Competition. A concerto is a major work for a soloist with an orchestral accompaniment. We look forward to hearing Celestine and the orchestra later this term in an informal performance.

Michael Powells AOL Connection
Washington -- Not long after America Online Inc. began its
heavy lobbying of the Federal Communications Commission last summer, Commissioner Michael
Powell decided to have a chat with the agency's ethics czars.
Powell needed to answer this question: Could he continue to
participate in the cable-Internet unbundling debate instigated by AOL now that his father
-- retired Gen. Colin Powell -- was a director on the online company's board?
Even though the whole scenario sounded very
Washington-cozy, the FCC told Powell that yes, he could.
"I think I take ethics more seriously than most people
I know," he said.
"We did a full evaluation to make sure [Powell could
In the end, Powell demonstrated little enthusiasm for AOL's
position, saying the FCC should encourage competition for cable's facilities rather than
mandate third-party access.
When the unbundling debate was raging last fall and early
winter, the cable industry never suggested Powell might have a conflict of interest. A
Washington cable lobbyist said the industry's silence was intentional because it knew
Powell had doubts about AOL's views.
Powell even joked that as things turned out, the decision
on AOL was "probably the one that wished I wasn't" involved in.
Cable's silence with regard to Powell stands in contrast to
its comments on Scott Cleland, a prominent Washington telecom analyst who predicted the
FCC would eventually force cable operators to open their networks to unaffiliated Internet
service providers.
Then-NCTA spokeswoman Torie Clarke complained last November
that Cleland, managing director of Legg Mason Precursor Group, failed to mention in his
cable unbundling reports that Legg Mason's mutual funds held about $700 million in
AOL stock.
Cleland responded that his group is walled off from the
mutual fund family and that he had no knowledge of Legg Mason's AOL holdings.

The University of California, San Francisco not only attracts major government dollars, but its renown as a top medical research institution also has the eye of Big Pharma. In March 2013, Pfizer ($PFE) sought out UCSF as a partner for its already robust Centers for Therapeutic Innovation program to develop new small-molecule drug candidates. Under the agreement, UCSF will receive funding from Pfizer to support preclinical and clinical development of small-molecule research programs. If drug candidates meet certain objectives, Pfizer would help move the drugs into clinical trials. UCSF will receive milestone payments and royalties if a product created through the collaboration is commercialized.
In June, researchers at UCSF uncovered a genetic mechanism that may explain why some patients with multiple sclerosis progress more rapidly to a severe stage of the disease than others. In a mouse model of MS, the researchers found that early onset of a more serious form of the disease was connected to the absence of the gene Tob1 in CD4+ T cells, a type of immune cell. The findings, published in the Journal of Experimental Medicine, could eventually be a useful diagnostic to detect the course and severity of MS in different patients, ultimately helping physicians tailor personalized therapies.
In other notable research last year, scientists at UCSF found that they could halt and reverse tissue scarring in the liver, kidneys and lungs of mice by targeting a family of proteins on the surface of certain cells. The approach could be used to treat the same kind of scarring in humans--called fibrosis, which is related to chronic diseases and a major contributor to nearly half of all deaths in developed nations.

The RC44 World Championship Marina de Sotogrande had a worthy winner today in Igor Lah and his Team Ceeref crew, the second occasion the Slovenian team has claimed this prize (after Puerto Calero, Lanzarote in 2013).
But this was only after some anxious moments off the Andalusian port, as Lah's crew slogged it out with local heroes, John Bassadone's Peninsula Petroleum from nearby Gibraltar.
Day four of fleet racing began with Team Ceeref holding a six point advantage over her rival. In today's first race, Peninsula Petroleum won while Team Ceeref came home a disappointing sixth in the 11 boat fleet. This levelled the scoreline between the two boats. In race two, both Team Ceeref and Peninsula Petroleum were deep in the fleet but fought back to finish second and fourth respectively. This left John Bassadone's team having to finish at least two boats ahead of Team Ceeref in the last race.
In this scenario some match racing was inevitable and the two boats engaged in the pre-start with Peninsula Petroleum gaining a small advantage. Sadly for them the race committee called a general recall. On attempt number two Peninsula Petroleum started in traffic near the committee boat while Team Ceeref was in clear air mid-line.
By the top mark Lah's team was holding fourth while Bassadone's was in sixth. However both boats were on the ascent and on the next beat moved into second and third respectively. With some careful covering from Team Ceeref, these positions they maintained until the finish, handing the Slovenian team victory by three points.
'It feels great, like the last time,' enthused Lah. 'This was tougher, because each year it gets harder, with each team improving a lot. We had a pretty tense race with Peninsula Petroleum, when we were match racing. We've needed a bit of time to come together as a team and to really get used to how we work with each other.
Team work was the most important thing and the preparation of the boat was perfect.'
Not unusual in the high calibre RC44 fleet, Team Ceeref has an outstanding crew. Among others, this included British navigator Adrian Stead, Dutch Volvo Ocean Race and America's Cup winning main sheet trimmer Dirk de Ridder plus headsail trimmer, Kiwi Jon Gunderson and Italian bowman Matteo Auguardo, plus three other Italians in the middle of the boat, including their 113kg man-mountain grinder, Simone Mina.
We knew it was going to be a tough day,' recounted Stead. 'We said that we'd win the Worlds today by sailing well, not by looking in front or over our shoulder. It was about fighting back although it was more of a one way track today, so getting back was tough.
'In the final race we were happy to get a lane out and get a good launch – we were a boat length ahead right out of the start.'
Disappointed not to win on his home waters, John Bassadone congratulated Lah and Team Ceeref: 'We tried to approach today as if it was any other. Our objective was to sail like we know we can sail and to see where we would end up.
Of their win today, Törnqvist said: 'We got an okay start – we wanted to go to the right, which was really strong, we found a lane and from then on it was quite easy. We managed the shifts and when you're on top, its easy. It was the perfect race of the day for us.
'It was a wonderful day and great sailing – it doesn't get better than that. Our team work and communication was all free flowing so we were feeling good.'
Among the 11 teams, competing at this RC44 World Championship Marina de Sotogrande six won races. These included defending World Champion, Team Nika of Vladimir Prosikhin and Bronenosec Sailing Team of Vladimir Liubomirov, the two stand-out campaigns of 2015, Team Nika also being the defending World Champion.
From Spain, the 2016 RC44 Championship moves on to the RC44 Portsmouth Cup over 13-17th July.
