- Abstract
- Cold massive cores are one of the earliest manifestations of high-mass star formation. Following the detection of SiO emission from G333.125−0.562, a cold massive core, further investigations of the physics, chemistry and dynamics of this object has been carried out. Mopra and NANTEN2 molecular line profile observations, Australia Telescope Compact Array (ATCA) line and continuum emission maps and Spitzer 24 and 70 μm images were obtained. These new data further constrain the properties of this prime example of the very early stages of high-mass star formation. A model for the source was constructed and compared directly with the molecular line data using a 3D molecular line transfer code –mollie. The ATCA data reveal that G333.125−0.562 is composed of two sources. One of the source is responsible for the previously detected molecular outflow and is detected in the Spitzer 24 and 70 μm band data. Turbulent velocity widths are lower than other more active regions of G333 which reflects the younger evolutionary stage and/or lower mass of this core. The molecular line modelling requires abundances of the CO isotopes that strongly imply heavy depletion due to freeze-out of this species on to dust grains. The principal cloud is cold, moderately turbulent and possesses an outflow which indicates the presence of a central driving source. The secondary source could be an even less evolved object as no apparent associations with continuum emissions at (far-)infrared wavelengths.

Strong Arm Technologies has won the Rochester and New York State Business Plan Competitions for its innovative new product, the Strong Arm Vest.
Designed to redistribute weight to stronger, more stable areas of the torso making lifting easier, the Strong Arm also constrains the wearer's movement, thus ensuring the utilization of proper posture. This ergonomic design mitigates injury thereby increasing worker productivity and saving companies a considerable amount of money.
Officially formed in January of this year, the Strong Arm crew has been hard at work on their flagship product for a year and a half. Partners Sean Petterson and Justin Hillery got their start in the Center for Student Innovation working with mentors such as Carl Lundgren who Petterson credits with having followed them from the beginning stages all the way through to development.
After their win in the New York State Business Plan Competition, Strong Arm went on to The Bright Forum in Buffalo where they won Best Pitch. Most recently, they were accepted into the Mass Challenge, a four month competition during which the Strong Arm team will be spending time in Boston.
Having also won Best Pitch and Best Technological Innovation from the NCIIA in California, Strong Arm has been asked to present at the Ergonomics Conference and Exposition. When asked about their product, company official Tayler Swanson replied, "We are creating a quality product with real human impact."
"We want to thank everybody's help from RIT, specifically Carl Lundgren, John Schull, Rich Notargiacomo, and Bill Jones. We'd also like to thank the RIT structure. The Strong Arm success has absolutely been enabled by the system RIT has been developing to help student innovation," CEO Sean Petterson said. "And of course, I want to thank my mother."
As of the posting of this article, Strong Arm is working with one of several major big box stores to develop the Strong Arm Vest and bring it to market. They are also in the middle of testing their product with a company who is using the Strong Arm Vest on a number of employees and the testing is going "incredibly well".

Visiting Ghanaian works to help disabled
MONTPELIER After polio paralyzed her below the waist as a child, Sefakor Komabu-Pomeyies mother carried her on her back to school every day so she could get an education.
Komabu-Pomeyie is from Ghana and she is not letting that education go to waste as she is interning at the Vermont Center for Independent Living in Montpelier, a nonprofit organization that works to promote the dignity, independence and civil rights of Vermonters with disabilities.
She came to the United States as a Ford Foundation scholar and is working toward her masters degree in policy analysis from the School of International Training in Brattleboro.
Komabu-Pomeyie is an advocate for others like her who are physically disabled. She said in her native country, those who use wheelchairs or crutches because of a physical disability have hard lives. Taxis do not stop to pick them up, toilets, which are holes in the floor, are near impossible to use by someone who is paralyzed, and schools have stairs that are difficult to navigate in a wheelchair, she said.
Komabu-Pomeyie said Ghana has laws on the books to help the physically disabled by making buildings accessible. The problem is the government fails to implement these laws, Komabu-Pomeyie said. The government looks the other way when it comes to the physically disabled, Komabu-Pomeyie said, because they do not have any personal interactions with the physically disabled and treat them as though they dont exist.
People normally dont (think) about disability unless it happens to them or unless it is close to them, she said.
The actions the government takes to this day show that the physically disabled are not a priority in Ghana, Komabu-Pomeyie said.
You said every building should be accessible, yet you the government build so many bridges without access (for the physically disabled), she said.
Ghana does not have a great track record when it comes to the physically disabled. Historically, people who had a physically disabled person in their family were considered cursed by the gods. And Kombau-Pomeyie said while today people do not openly call you cursed, the stigma is still there so the physically disabled feel like second-class citizens.
Komabu-Pomeyie said in the past those born with a physical disability, or who became disabled as children because of an accident, were dumped in the desert or a forest. Komabu-Pomeyie works with a woman who was born without a hand and dumped in the desert, but was picked up by a minister and is now a teacher.
Komabu-Pomeyie said her mother was ridiculed for taking care of her. People would stare and tell her to stop wasting her time.
Things have improved in Ghana, as Komabu-Pomeyie appears on radio and television stations there something that a disabled person could never have dreamed of in the past to talk about the problems people like her face with accessibility challenges.
Komabu-Pomeyies mother instilled in her the belief that getting an education is the way to improve ones life. Komabu-Pomeyie is a French teacher in Ghana and her main interest is improving accessibility in schools for the physically challenged. While the deaf and blind attend special schools in Ghana, physically disabled children are mainstreamed in the general student population, so she knows firsthand the hardship of trying to navigate the entrances to public schools.
To address this issue, Komabu-Pomeyie is working with the WaWa Project, a nonprofit organization that works with children with disabilities in West Africa, to retrofit a school in Ghana to make it handicapped-accessible with ramps and raised toilets. When finished, this school will serve as a model for renovation projects at other schools around the country.
Komabu-Pomeyie is also trying to get a handicapped-accessible van donated so that she can drive the physically disabled people she works with to the hospital, meetings, or for any other reason they may need transportation. She currently has to drive the people around in her own car, which she says is too small, and if three physically disabled people need to go somewhere then she has to make multiple trips.
When Komabu-Pomeyie came to the United States last year she expected the plight of the physically disabled to be much different here than in Ghana. She says the Americans with Disabilities Act does a good job of keeping those who break accessibility laws accountable, but she adds that people with physical disabilities still have a hard time.
Komabu-Pomeyie is currently staying with people who volunteered to lend her a room in their house because she has nowhere else to stay. The room was only supposed to be used for a couple days, but she has been there since September. Komabu-Pomeyie thought she had lined up a room that she could rent, but it fell through because the room wouldnt accommodate her needs. The Vermont Center for Independent Living has been working to find an affordable, accessible room for her, but so far has been unsuccessful.
Ironically, the Americans with Disabilities Act is standing in the way of progress for the disabled in other nations, according to Komabu-Pomeyie. She is trying to get the United States to ratify the United Nations Convention on the Rights of Persons with Disabilities, a landmark treaty intended to protect the rights and dignity of persons with disabilities.
Komabu-Pomeyie said the United States hasnt signed the treaty because of concerns that doing so could undermine the Americans with Disabilities Act.
Komabu-Pomeyie said that is simply not true. She wants the U.S. to sign the treaty as an example to other countries to follow suit.
If you ratify (the treaty) as a country, it has a reflection on those countries, she said.
Komabu-Pomeyie is a recent recipient of the World of Difference 100 Award given by The International Alliance for Women. The TWIA each year honors 100 women from around the globe for their work. Komabu-Pomeyie was recognized for the work she has done on behalf of the physically disabled in her community.
She has also worked with the United Nations Commission on the Status of Women In New York.

Lexmark, like so many other worldwide corporations, has deepened its commitment to economic, social and environmental sustainability. Deeper corporate commitments to sustainability and social responsibility and regular and formal documentation of corporate efforts in these areas are helping to bring significant issues to critical mass. We are hopeful that these efforts are resulting in an enhanced quality of life for people around the globe.
During the recent period of global economic turbulence – when many businesses were forced to make difficult reductions in many areas of their operations – Lexmark became more determined than ever to align our financial success with responsible global citizenship. We maintained our commitment to equitable social and environmental practices and strengthened our position as a thoughtful and positive steward of global resources.
There are several reasons that sustainability and social responsibility are priorities at Lexmark. First and foremost, it's the right thing to do. Beyond that, it makes good business sense. Environmental and social responsibility have become a primary focus for consumers. Likewise, investors expect businesses to operate sustainably. Additionally, newly enacted legislation and emerging voluntary standards can limit market access for companies that don't offer sustainable products or operate in a responsible manner.
This report outlines Lexmark's environmental and social responsibility efforts, addressing our strategy, our achievements and our plans for the future. CSR issues of particular materiality to Lexmark – environmental responsibility, workplace diversity and accessibility – are discussed at length and in depth.
At the close of 2009, we set a goal to dramatically increase our level of transparency and to establish programs to fill gaps in our CSR programs as identified by external analysts and through internal analyses. I'm proud to report that both of these goals have been achieved. With this report we have reached our highest degree of transparency by addressing 100 percent of all Global Reporting Initiative (GRI) performance indicators. Additionally, Lexmark has been recognized by external organizations for its environmental and social responsibility efforts. In 2010, Lexmark was selected for inclusion in the Maplecroft Climate Innovation Indexes. Lexmark was rated seventh overall and we were first in our sector (technology) and sub-sector (computers). In addition, we were the second-ranked company in emissions reductions of the 350 companies rated. Our company was also listed on the most recent 100 Best Corporate Citizens List compiled by Corporate Responsibility Magazine, achieving an overall rank of 60 with higher rankings of No. 6 on environment and No. 8 on climate change.
I believe our record on sustainability issues and our reporting on them is a good one, but there's always room for improvement. We intend to remain diligent in our efforts to maintain a leadership position in this pursuit. Lexmark's senior management is charged with embedding environmental and social consciousness into our corporate culture. That process will help ensure those issues are thoughtfully considered in all decisions made at every level of our company. The way in which we conduct business is as important to us as the quality of our products.
Going forward, we will continue to support the United Nations Global Compact (UNGC) and will conduct business in a manner that is sensitive to societal and environmental issues that align with the principles of that compact.
In closing, let me express how proud I am that Lexmark employees have overwhelmingly embraced the concept of social and environmental responsibility. That reflects extremely well on our company and I am grateful to all of them for that dedication.
Paul A. Rooke
Chairman and Chief Executive Officer
Lexmark International, Inc.
