![]() #Lightsmith lasers skin#Their ultrafast photophysical reactions can alter the chemical structure of DNA - leading to damages to the genetic code - as proven by the increased skin cancer risk observed for patients treated with thiouracil for its immunosuppressant properties. Understanding the changes that follow UV-excitation in thionucleobases is of great importance for the study of light-induced DNA lesions and, in a broader context, for their applications in medicine and biochemistry. ![]() A short review is presented of the main experimental properties of x-ray FELs, and the results are discussed of the most recent research to improve their longitudinal coherence properties, increase the peak power, and generate multicolor spectra. This paper reviews the physical principles, the theoretical models, and the numerical codes on which x-ray FELs are based, starting from a single electron spontaneous undulator radiation to the FEL collective instability of a high density electron beam, strongly enhancing the electromagnetic radiation field intensity and its coherence properties. Using these novel and unique capabilities new scientific results are being obtained in atomic and molecular sciences, in areas of physics, chemistry, and biology. ![]() They generate coherent photon pulses with time duration of a few to 100 fs, peak power of 10 to 100 GW, over a wavelength range extending from about 100 nm to less than 1 Å. Web: TheLightSmith.X-ray free-electron lasers (x-ray FELs) give us for the first time the possibility to explore structures and dynamical processes of atomic and molecular systems at the angstrom-femtosecond space and time scales. Todd Smith also runs Architectural Materials Co., which his father, Bill, founded in 1969. Including installation, rates start at $675 and increase based on the length of the tube to run from roof to ceiling, Smith said. The daylighting systems, which Smith said can be installed in about two hours, allow for natural sunlight to be passed from the roof to the interior of the home. The LightSmith offers the sale and installation of Solatube daylighting and solar-powered attic fans. Currently run out of their home, Ali Smith said renovations are under way for a 1,100-square-foot showroom and office at 1650 St. Husband-and-wife Todd and Ali Smith in June opened The LightSmith as the regional dealership for Solatube International’s daylighting systems. Sunday through Thursday and 11 a.m.–11 p.m. The menu features grilled steak, chicken, ribs and fish, and offers seasonal specials such as a lobster-stuffed filet. The $3 million, 6,200-square-foot Springfield restaurant, which is managed by Melissa Meadows, employs about 80 and seats up to 240, according to spokeswoman Tara Gray. Orlando, Fla.-based Darden Restaurants operates about 360 of the 30-year-old Western-style steak houses among its 1,900 restaurants, including Red Lobster and Olive Garden. ![]() ![]() Monday through Wednesday and Friday 9 a.m.–8 p.m. The clinic offers laser treatments, sun damage repair, permanent cosmetics, acne treatments, teeth whitening, laser hair removal, vein erasure and skin tightening. DermaHealth employs 15, and contracts with three independent physicians. Battlefield Road and increases the number of patient rooms to 15 from seven, said owner Cheryl Briggs, who declined to disclose renovation costs. The new site is more than double the previous space at 1902 E. 8, DermaHealth Laser & Skin Care Clinic LLC moved to 6,000 square feet at 1850 S. ![]()
