Go here: http://sheldonbrown.com/gears/ With a 48t chainring, going from a 16t cog to an 18t cog will make an 8.7 gear inch difference. A big difference. From 78.8" to 70.1". For small differences, change the chain ring instead of the cog.
Shido and I worked on our first Re(pubelick) Bike on Friday. I thought Bianchi Pistas, SE Draft, IRO Complete bikes, and pake frames were bad enough. Urbane Outfitters has lowered the bar to a point I thought not possible.
An 1894 engraving of Attila from Charles Horne's Great Men and Famous Women, an image adapted from an antique medal. In depicting Attila with horns and goatish physiognomy, the engraver stressed the diabolical aspects of his character. He called himself flagellum Dei , the scourge of God, and even today, 1,500 years after his blood-drenched death, his name remains a byword for brutality.
Serotonin Syndrome is a potentially life-threatening condition that is caused by elevated serotonin concentrations in a person's system. This condition may be brought on by the use of "serotonergic" drugs, which include several types of antidepressants such as SSRIs (selective serotonin reuptake inhibitors) like Paxil and Celexa , tricyclics like amitriptyline and trimipramine , and MAOIs (monoamine oxidase inhibitors) like Nardil and Parnate . Other substances which may contribute to serotonin syndrome include St. John's wort , cocaine, L-tryptophan, lithium, amphetamines, ecstasy and LSD. In addition, some non-psychiatric drugs may affect the level of serotonin in the bloodstream. For this reason, it's essential that all your doctors who prescribe medications always know all medications and supplements you are currently taking.
Psychomotor agitation is a series of unintentional and purposeless motions that stem from mental tension and anxiety of an individual. This includes pacing around a room, wringing one's hands, pulling off clothing and putting it back on and other similar actions. In more severe cases, the motions may become harmful to the individual, such as ripping, tearing or chewing at the skin around one's fingernails or lips to the point of bleeding. Psychomotor agitation is a symptom typically found in major depressive disorder or obsessive-compulsive disorder , and sometimes the manic phase in bipolar disorder , although it can also be a result of an excess intake of stimulants . The middle aged and the elderly are more at risk to express this condition [ citation needed ] .
Hypervigilance is an enhanced state of sensory sensitivity accompanied by an exaggerated intensity of behaviors whose purpose is to detect threats. Hypervigilance is also accompanied by a state of increased anxiety which can cause exhaustion . Other symptoms include: abnormally increased arousal , a high responsiveness to stimuli , and a constant scanning of the environment for threats. [ 1 ] [ 2 ] In hypervigilance, there is a perpetual scanning of the environment to search for sights, sounds, people, behaviors, smells, or anything else that is reminiscent of threat or trauma. The individual is placed on high alert in order to be certain danger is not near. Hypervigilance can lead to a variety of obsessive behavior patterns, as well as producing difficulties with social interaction and relationships. Hypervigilance can be a symptom of post traumatic stress disorder [ 3 ] (PTSD) and various types of anxiety disorder .
We can never accuse Google of thinking small. The search giant today unveiled a website for “Solve for X,” a conference for big thinkers to discuss “radical technology ideas for solving global problems.” Yes, it sounds ridiculously geeky, but it’s the sort of project from Google that could end up creating some truly next-generation technology and solutions. (Let’s not forget this is the company that is already pioneering self-driving car technology .) Google seems to be aiming directly at the people who get hot and bothered over the much-hyped TED conference (this reporter included). This conference may have something to do with Google’s poaching of senior Apple director Simon Prakash for a “secret project,” though right now it’s unclear if he’s working on Solve for X.
A bile bear in a “crush cage” on Huizhou Farm, China. Bile bears or battery bears are Asian black bears ( Ursus thibetanus ) kept in captivity to harvest bile , a digestive juice produced by the liver and stored in the gall bladder . When extracted, the bears’ bile is a valuable commodity for sale as an ingredient in traditional Chinese medicine . [ 1 ] The bears are also known as moon bears because of the cream-colored crescent moon shape on their chest.
My eight-year-old son, Joel, comes into my office to ask if there's a worse swearword than fuck. "No," I say. There's a silence. "You're lying," he says.
After 30 years spent drilling through a four-kilometer-thick ice crust, researchers have finally broken through to a unique subglacial lake. Scientists are set to reveal its 20-million-year-old secrets, and imitate a quest to discover ET life. The Vostok project breathes an air of mystery and operates at the frontiers of human knowledge.
“This is a book not about the decline of America but rather about the rise of everyone else,” I note at the very outset. I am optimistic about America, convinced that it can prosper in this new world and remain the most powerful country on the planet. But I argue that the age of American unipolarity — which began with the collapse of the Soviet Union — has ended. For a quarter-century after the collapse of communism, the United States dominated the world with no real political or economic competitors.
A Galaxy Full of Alien Planets (Infographic) | Extrasolar Planets & Search for Life | Exoplanets & NASA Kepler SpacecraftThe latest study on the likely distribution of planets in our galaxy has found that at least 160 billion alien worlds exist in our Milky Way. Astronomers say the survey, based on estimates and computer projects, means that at least 1.6 planets circle each star in our galaxy. See how the alien planet population of our galaxy stacks up in the SPACE.com infographic above. Embed: Paste the code below into your site.
8 February 2012 Last updated at 09:29 ET By Jonathan Amos Science correspondent, BBC News Vostok station is one of the most difficult places to work on Earth Russian scientists are reporting success in their quest to drill into Lake Vostok, a huge body of liquid water buried under the Antarctic ice. It is the first time such a breakthrough has been made into one of the more than 300 sub-glacial lakes known to exist on the White Continent.
Google Chrome allows you to create profiles which makes it easy for households that share the same computer. This allows each user to have their own profile instead of having to login and logout of their various web accounts each time they use the browser. This feature is also beneficial to users who don’t share their computer. You can create focused profiles that allow you to eliminate distractions such as social networks, email, etc. I do a great deal of web development and online consulting work and also go to school online.
The French interior minister has said he is standing by his remarks that not all civilisations are equal, even as critics denounced his comments as dangerous and xenophobic. "I do not regret [the comments]," Claude Gueant said on Sunday, though he accused critics of taking them "out of context" "Contrary to what the left's relativist ideology says, for us all civilisations are not of equal value," Gueant, who is also responsible for immigration, told a gathering of right-wing students on Saturday.
