The researchers concluded that they have “identified a new association with the HDAC9 gene region in large vessel stroke”. They also stated that “the mechanism by which variants in the HDAC9 region increase large vessel stroke risk is not immediately clear.” In this study, researchers have identified a genetic variant |
in the HDAC9 gene that is associated with a subtype of ischaemic stroke called a large vessel stroke. Large vessel strokes occur when one or more of the arteries supplying blood to the brain become blocked. In this type of study, the genetic variants identified as being associated with a |
condition are not necessarily the cause of the increase in risk. Instead, they may lie near another variant that is responsible for the effect. In order to unlock the role of the HDAC9 gene, researchers will now need to study it and the region surrounding it more closely, both to |
confirm whether the variation in this gene is responsible for the increase in stroke risk and, if so, how it has this effect. Genetic, medical and lifestyle factors are likely to contribute to stroke risk. In addition, multiple genetic factors may potentially contribute to the risk. It’s important to note |
that although having higher-risk genetic variants increases the risk of having a stroke, it does not guarantee that a person will have one. Equally, people who do not have any associated variants can still be at risk of a stroke because of lifestyles factors such as smoking, drinking and their |
diet. This well-designed study found an association between a new genetic variant and one type of stroke. As yet, it is not possible to say whether this finding will lead to the development of new treatments for large vessel strokes. Search for a job Search for a car Search for |

Like the Republican party, the Democratic party also cracked beneath the weight of the issues at hand. States that favored slavery in the territories walked out of the Democratic convention |
at Charleston, preventing nominee Stephen Douglas from winning the party endorsement. A reconvened convention eventually nominated Douglas, but kept territory slavery out of the platform altogether. As a result of |
disagreements over the issue of slavery, splinter parties formed. The Southern Democratic Party spun off from traditional Democrats to nominate John Breckenridge, an advocate of slavery in the West. Republican |
breakaways formed the Constitutional Union Party. They nominated John Bell who would not address the issue of slavery at all, but rather spoke of upholding the Constitution. With four candidates |
in the race, Lincoln won the 1860 election. But by the time he took office in March of 1861, seven southern states had already seceded from the Union. When the |
first shot rang out at Fort Sumter, just one month after Lincoln took office, the Civil War began. Lincoln's hopes for peacefully preserving the union were dashed. In 1863, Lincoln |
issued the Emancipation Proclamation. He also promoted a Constitutional Amendment to permanently abolish slavery. These bold steps marked a shift from Lincoln's more moderate campaign position on slavery issues. They |
also shifted the focus of the war from preserving the union to freeing the slaves. Remarkably, the election of 1864 was not suspended during the bloody Civil War. Union soldiers |
were given absentee ballots or furloughed to permit them to vote. With mounting Union victories, the votes of soldiers and the campaign slogan, "Don't switch horses in mid-stream," Lincoln won |
the election. Sadly, as this 1864 campaign song strangely foreshadows, Lincoln did not live to see passage of the 13th Amendment that abolished slavery forever. He was assassinated just five |
days after Ulysses S. Grant celebrated victory over Robert E. Lee at Appomattox. Lincoln's presidency causes one to wonder: - Why he changed his position on the issue of abolition |
during his presidency? - Whether these changes might affect the way we view his original platform? - What were Lincoln's priorities when he created his original platform? How did the |
advent and progress of the war affect these priorities? - To what extent did Lincoln's original platform represent his personal views? To what extent did it reflect a desire and |

- Coming Soon. master naturalist for teachers The Teacher’s Master Naturalist program incorporates best practices for systemic school reform - it requires that the school’s principal initiate the partnership, and that each school send a team of lead teachers who |
are responsible for implementing their school’s science and math programs. LCI adapted its Master Naturalist curriculum to provide a program that teaches teachers how to use experiential learning most effectively to improve their school’s science and math programs. Participants engage |
in research and educational experiences designed to empower them to teach from a first person perspective, sharing their personal adventures with their classes. During workshops, teachers set and check traps for fish, reptiles, and amphibians, conduct flora and fauna surveys, |
and collect and identify marine invertebrates and other organisms. As teams of teachers graduate from the course they continue to receive support for school-based projects from LCI staff and the local Master Naturalist association. The program began in 2007-2008 with |
two pilot schools, and has expanded to eight schools during the 2009-2010 school year. Teachers receive Master Naturalist certification and continuing education credit after completing the year-long program. learning expeditions schools The goal of the Learning Expeditions Schools program is |
to use environmental science as a theme to integrate learning about science, social studies, math, and language arts. The program is a partnership between the LowCountry Institute, Clemson University's Youth Learning Institute, and Beaufort County Schools. The interdisciplinary lessons include |
field trips, virtual field trips using video and PowerPoint programs, and hands-on activities in the classroom. These lessons use science standards to teach students how geography and climate determine plant communities present which, in turn, influence the economy and the |
history of the region. Math is integrated into all lessons through science and history-based word problems. Pilot schools for this program are Shell Point Elementary, Shanklin Elementary, and Robert Smalls Middle School. During the 2012-2013 school year, the program will |
be made available to other district schools that wish to participate. - Grants: Several schools have been recipients of grants from LCI to create outdoor classrooms and natural areas using native plants to teach students about pollination, plant lifecycles, and |
native habitats. - Hands-on programs: LCI staff and volunteers conduct programs at schools to teach students about the plants and animals native to the Port Royal Sound System. - School field trips: LCI is able to invite a limited number |
of schools each year to participate in field trips on Spring Island where students learn about habitats and animals of the lowcountry. click image to see photos of our school programs |
By Sue Weishar, Ph.D. On August 25, 2008, the small town of Laurel, Mississippi was the site of the largest single workplace site raid in U.S. history. Early that morning hundreds of Immigration Control and Enforcement (ICE) agents swooped down on the Howard Industries plant in Laurel, which produces electric |
transformers, and began rounding up workers. Anyone who appeared to be of Hispanic origin was separated from other workers and escorted outside to a fenced yard. Roads around the sprawling plant were blocked and ICE helicopters hovered overhead. One resident thought there had been a terrorist attack.1 For the 595 |
immigrant workers that were arrested that day, there might as well have been. By evening of that long, hot summer day, 488 immigrant workers, many in handcuffs, had been transported on dozens of ICE buses to an immigrant detention center in Jena, Louisiana, four hours away—ripped apart from their families |
and a community they had come to think of as home. Another 107 persons, mostly women, had been deemed “humanitarian” cases2 and were released with electronic monitoring devices attached to their ankles. They were forced to wear these devices day and night for 22 months. In the midst of such |
terror, a small Catholic church became the center of solace and assistance. Several Catholic agencies and the Loyola University New Orleans Law Clinic also played key roles in assisting raid victims. This article examines the Church’s response to the raid in Laurel,3 and how a small Catholic community in the |

Boulder trails are common to the interior of Menelaus crater as materials erode from higher topography and roll toward the crater floor. Downhill is to the left, image width is |
500 m, LROC NAC M139802338L [NASA/GSFC/Arizona State University]. Most boulder trails are relatively high reflectance, but running through the center of this image is a lower reflectance trail. This trail |
is smaller than the others, and its features may be influenced by factors such as mass of the boulder, boulder speed as it traveled downhill, and elevation from which the |
boulder originated. For example, is the boulder trail less distinct than the others because the boulder was smaller? What about the spacing of boulder tracks? The spacing of bounce-marks along |
boulder trails may say something about boulder mass and boulder speed. But why is this boulder trail low reflectance when all of the surrounding trails are higher reflectance? Perhaps this |
boulder trail is lower reflectance because the boulder gently bounced as it traveled downhill, and barely disturbed a thin layer of regolith? The contrast certainly appears similar to the astronauts' |
footprints and paths around the Apollo landing sites. Or, maybe the boulder fell apart during its downhill travel and the trail is simply made up of pieces of the boulder |

When you work on introducing a new technology to a population and region, you discover lots of intriguing impediments to that introduction that you’d never have imagined. Yesterday (October 11, 2012) the Maine Fuel Board voted to allow Maine Energy |
Systems to engage in an “Emerging Technologies” project with them that might lead to elimination of one of those impediments for the pellet central heating industry in the State of Maine. Maine is unique in its licensure of technicians for |
of license detail.) The need for this rule apparently arose from three potential hazards associated with “solid fuel” boilers: the possibility for a thermal run-away during a power outage as combustion continues on a load of fuel while circulation fails |
due to lack of power, high chimney temperatures, and high boiler surface temperatures. As highly sophisticated automatic pellet boilers made their way into the American market, they were defined in Maine as “solid fuel” appliances because pellets are solid. While |
that seems innocent and logical enough, the categorization has one substantial flaw and it creates one significant impediment to product growth in the marketplace. State-of-the-art pellet boilers display none of the attributes that led to the perceived need for “solid |
fuel” rules in Maine. The rules were devised for cordwood boilers and coal stoker boilers that can hold a significant charge of fuel at any given time. The combustion of that fuel is relatively uncontrolled. Pellet boilers burn a very |
small quantity of fuel at any given time, and the combustion of that fuel is highly controlled. Combustion stops almost immediately if the power goes out, hence, no excessive heat can be produced during a power outage. Cordwood boilers and |
coal stoker boilers can produce very high stack temperatures. The exhaust gas temperatures from state-of-the-art pellet boilers are very much like those of modern oil boilers. In fact these boilers are so efficient, the stack gas temperature is often quite |
cool, 250F, or so, but it never exceeds 400F. Therefore, high chimney temperatures never occur. Old cordwood and coal stoker boilers could develop high surface temperatures making installed distance from combustible surfaces important. The surface temperature of these state-of-the-art pellet |
boilers is the same as the temperature of the room. The heat exchangers are extremely well insulated to achieve the desired efficiencies. So, the worry about proximity of flammable materials due to high boiler surface temperatures is not justified with |
these boilers. Because these highly sophisticated boilers are lumped in the same category as cordwood boilers and coal stoker boilers, “solid fuel” license holders must install them in Maine. There are many fewer “solid fuel” license holders than ordinary oil |
license holders, so scheduling boiler installations in this rapidly growing segment is very challenging in the busy times of the year. Other busy technicians find it hard to justify studying for a test that focuses generally on boilers they’ll never |
see, so they’re not inclined to prepare for the “solid fuel” test to install pellet boilers as they’re just beginning to make a mark on the marketplace. The Emerging Technologies Project On October 11, 2012, the Maine Fuel Board approved |
a request made by Maine Energy Systems for a year long project intended to confirm the company’s assertion that their boilers, and those similar to them, can be installed by oil boiler license holders who have been suitably trained in |
the differences between pellet boilers and oil boilers. This is great news for the pellet industry in Maine as the State’s boiler inspectors will inspect some, or all, of these installations and, thereby, become much more familiar with these sorts |
of systems. If the project leads to the anticipated conclusion, the request to re-categorize the boilers for licensure requirement purposes should be reasonably received. We have little doubt that the Project will reach successful conclusion as these very same boilers |
are installed throughout the Northeast by the same technicians who install oil boilers and who have been trained at Maine Energy Systems in fuel handling and burner adjustment. In the meantime, Maine Energy Systems will be training oil boiler technicians |
in the installation of their equipment to ensure that all who choose to install the MESys AutoPellet boiler can do it this heating season on a schedule that works for them. Dutch Dresser is the Managing Director of Maine Energy |

the rock and growing into a germling (Hawkins & Jones, 1992). Ulva intestinalis is generally considered to be an opportunistic species, with an 'r-type' strategy for survival. The r-strategists have a high growth rate and high reproductive rate. For instance, the thalli of Ulva intestinalis, which arise from spores and |
zygotes, grow within a few weeks into thalli that reproduce again, and the majority of the cell contents are converted into reproductive cells. The species is also capable of dispersal over a considerable distance. For instance, Amsler & Searles (1980) showed that 'swarmers' of a coastal population of Ulva reached |
exposed artificial substrata on a submarine plateau 35 km away.
