Are you prepared for anything? Were you in a mad rush for supplies when the recent snow storms hit? Preparedness affects many different aspects of life. Included here are a few of the ways we stay prepared. And there’s also a book review on a great resource if you need help getting started.
We investigate here the configuration of dislocations emitted by a sharp crack tip in structural alloys, and the characteristics of plastic zone as a result of the accumulation of fatigue damage, which is still unknown and is crucial for understanding the underlying physics of the deformation process ahead of a crack tip. We report a significant lattice rotation in the plastic zone ahead of a fatigue crack at room temperature in Al 1100 H14 and Al 7075 T7, observed by employing X-ray diffraction XRD and transmission electron microscopy TEM. A series of high resolution XRD scans measured at different locations in the vicinity of crack tip showed variations in the relative intensities of 111, 200 and 220 Al peaks. The intensity of 111 peaks was observed to gradually increase as compared to that of the 200 peak as we approach the crack, suggesting lattice rotation as a result of fatigue crack growth at room temperature. We ascribe such rotation to glide of large number of dislocations along 111 planes across grain boundaries, which results in increase in the misorientation during crack growth. In addition, the cyclic deformation causes 200 increase in residual stress in Al 7075, but decrease in residual stress by 80 in commercially pure Al. Such a change in residual stress cannot be explained by the difference in dislocation density alone in the plastic zone. We demonstrate that the deformation associated with the lattice rotation is a major factor controlling the stress. These findings provide new insights on the role of lattice rotation on the deformation process under fatigue loading. This suggests a new the energy dissipation mechanism with implications for predicting material life under cyclic load.General Discussion / Re: Headwinds« on: June 06, 2010, 11:39:20 pm »
And don't be overly concerned with "gravity" being an impediment in the mountains. After the winds across the plains, the climbing can be a relief, and don't forget, there is always the downside to the mountains. Overcoming such adversary can only make you stronger, and you will be laughing about it in just a few weeks time and even feeling a bit chuffed with yourself. Plus, it makes a good story to tell your family and friends, and you can embellish it as much as you like, because YOU WILL HAVE DONE IT!

Dennis SA majority of African American students polled at a Midwestern university say lighter complexions are more attractive than darker ones
Kai Beasley:Kai Beasley:
The results, taken from a sample of 100 students, indicated that 96 percent of the men preferred a medium to light complexion in women while 70 percent of women found light skin of value in men.
This latest analysis of mating preferences explored a number of probable causes, all of which were rooted in the "colorism" prevalent from slavery through the 1960s, where lighter skin typically meant more privilege. The results were published in 2006 in the journal Race, Gender and Class.
Ashraf Esmail, a sociology and criminal justice professor at Delgado Community College in New Orleans, and Jas M. Sullivan, an assistant professor of political science and African American Studies at Louisiana State University, conducted the study.
According to Sullivan, its purpose was to test whether the color line continues to be a problem for the African American community.
“We know that there has been a preference for lighter skin in the past as a result of racism,” said Sullivan, “but we really wanted to know whether or not that preference still exists in the 21st century.”
The researchers asked 50 African American men and 50 African American women, all students at a large Midwestern university, to participate in semi-structured interviews. The university was not named in the study and Sullivan declined to provide the name for this story.
The students were all between 18 and 19 years old with complexions ranging from light to dark. Each subject was shown pictures of light, medium and dark-skinned men or women from fashion magazines and asked to rate the images based on attractiveness. In addition, each respondent was asked questions about their mating preferences in terms of skin color and about the value of skin color in the African American community.
One reason for the difference in answers between African American men and African American women, according to the authors, is that women tended to take more characteristics into account, such as lips, hair, eyes, height and style of dress, when determining a man's attractiveness.

The New York Times reported on May 30 that the most popular cosmetic products among modern Indian women are those that lighten the skin. Didier Villanueva, country manager for L’Oreal India, said in the article that "fairness creams" account for half of India’s skin care market.
In the 2005 book "Fair Women, Dark Men: The Forgotten Roots of Color Prejudice," Canadian anthropologist Peter Frost reports that lighter women were preferred in medieval Japan, Aztec Mexico and Moorish Spain, even before there was significant contact with Western ideology.

"Checkin was very smooth even thought we arrived late at nigh..."
I booked late for this trip as an extra on the way back to Chiang Mai but still managed to get a beautiful top floor room overlooking the inner courtyard and pool. The staff were always very friendly and helpful giving the hotel a safe and secure feel. A welcome poolside cocktail was a pleasant surprise. The room was generous, housekeeping efficient and the aircon was unexpectedly whisper-quiet. Breakfast was good value, which I would definitely include in future visits, but do order your morning coffee from the poolside bar separately. Restaurants, bars, cafes and taxis are all close by as are convenience stores. The main beach area of Jomtien, which is just a 10 minute walk, has been beautifully redeveloped with generous footpaths, easy beach access, clean sands and polite vendors offering shady umbrellas and food. A great place for an early morning walk. I would recommend The Agate and will be staying
