conclusions consequently, small diameter scnt interaction with nucleic acid bases is noncovalent. also, the results revealed that small diameter scnt interaction especially scnt (4, 4) with nucleic acid bases can be useful in practical application area of biomedical fields such detection and drug delivery. objectives hence, the quantum mechanics (qm) method based on ab initio was used for this ...

We explore the scattering approach to Casimir forces. Our main tool is the description of Casimir energy in terms of transition operators. The approach is valid for scalar fields as well as for electromagnetic fields. We provide several equivalent derivations of the formula presented by Kenneth and Klich Phys. Rev. Lett. 97, 160401 2006 . We study the convergence properties of the formula and h...

thermal conformational changes in human serum albumin (hsa) in present with a 10 mm phosphate buffer, at ph=7 have been investigated via circular dichroism (cd) and uv spectroscopic methods. the results indicate that temperature in a range of 25oc to 55oc could induce a reversible conformational change in the structure of hsa. the hsa phase transition corresponds to the physiological and pathol...

in this study, 10 normal volunteers and 5 sports-trained paraplegics with lesions between t6 and l2 were studied whilst walking with axillary crutches and knee-anlde-foot orthoses. all subjects walked at their preferred speed on a figureof- eight track. normal subjects also walked at slower and faster speeds. oxygen consumption, heart rate and rating of perceived exertion were measured. in norm...

We have measured the interaction energy and three-body recombination rate for a two-component Fermi gas near a narrow Feshbach resonance and found both to be strongly energy dependent. Even for de Broglie wavelengths greatly exceeding the van der Waals length scale, the behavior of the interaction energy as a function of temperature cannot be described by atoms interacting via a contact potenti...
