Environmental effects on quantum geometric phase and quantum entanglement
Günhan, Ali Can; Pak, Namık Kemal; Department of Physics (2008)
We investigate the geometric phase (GP) acquired by the states of a spin-1/2 nucleus which is subject to a static magnetic field. This nucleus as the carrier system of GP, is taken as coupled to a dissipative environment, so that it evolves non-unitarily. We study the effects of different characteristics of different environments on GP as nucleus evolves in time. We showed that magnetic field strength is the primary physical parameter that determines the stability of GP; its stability decreases as the magne...
Environmental sensitivities of plant populations and their practical importance. I: A case study on Pinus brutia Ten. Bitki populasyonlarinin cevresel duyarlilik degeri ve uygulamadaki onemi. I: kizilcam ornegi
Isik, K.; Kaya, Zeki (Scientific and Technical research Council of Turkey - TUBITAK, 1990-01-01)
Six Pinus brutia populations from different origins (Sarılar, Doyran, Murtbeli, Bük, Kapan and Hacıbekar) were planted in 4 common garden experiments located at different heights on the Taurus mountains near Antalya. Tree height at age 6 years and the number of growth cycles during the sixth growing season were measured; using these parameters environmental sensitivities of the populations were calculated. The Murtbeli population had the highest environmental sensitivity.

Environmental effects on the geometric phase
GÜNHAN, ALİ CAN; Turgut, Sadi; PAK, NAMIK KEMAL (2011-09-01)
The behavior of the geometric phase gained by a single spin-1/2 nucleus immersed into a thermal or a squeezed environment is investigated. Both the time dependence of the phase and its value at infinity are examined against several physical parameters. It is observed that for some intermediate ranges of the temperature and the coupling strength, the presence of squeezing enhances the geometric phase.
Environmental factors shaping the ecological niches of ammonia-oxidizing archaea
Bayramoğlu, Tuba Hande; Wittebolle, Lieven; Marzorati, Massimo; Verstraete, Willy (2009-09-01)
For more than 100 years it was believed that bacteria were the only group responsible for the oxidation of ammonia. However, recently, a new strain of archaea bearing a putative ammonia monooxygenase subunit A (amoA) gene and able to oxidize ammonia was isolated from a marine aquarium tank. Ammonia-oxidizing archaea (AOA) were subsequently discovered in many ecosystems of varied characteristics and even found as the predominant causal organisms in some environments. Here, we summarize the current knowledge ...
