Vibration-based damage detection with new operational response and waveform analysis methodology." MS ii ACKNOWLEDGEMENTS I would like to acknowledge the efforts of those who worked alongside me to make this work possible. Extensive field and laboratory testing was accomplished with the help of Dr. All three contributed their time and ideas to make(More)
Keratin (K) intermediate filaments can be divided into type I/type II proteins, which form obligate heteropolymers. Epithelial cells express type I-type II keratin pairs, and K7, K8 (type II) and K18, K19 and K20 (type I) are the primary keratins found in the single-layered intestinal epithelium. Keratins are upregulated during stress in liver, pancreas,(More)
In the mol-ecule of the title compound, C(15)H(15)NO(4)S, the dihedral angle between the two rings is 88.05 (7)°. The methyl ester group is nearly coplanar with the adjacent ring [dihedral angle = 2.81 (10)°], whereas it is oriented at 86.90 (9)° with respect to the plane of the ring attached to the -SO(2)- group. Weak intra-molecular C-H⋯O hydrogen bonding(More)
In the asymmetric unit of the title compound, C(15)H(16)N(2)O(5)S(2), there are two symmetry-independent mol-ecules which adopt similar conformations, with dihedral angles between the aromatic rings of 59.30 (8) and 61.81 (8)°, and dihedral angles between acetamide group and the benzene ring of 77.08 (10) and 78.40 (10)°. Each type of mol-ecule forms(More)
In the title compound, C(15)H(16)N(2)O(5)S(2), the dihedral between the two aromatic rings is 81.33 (6)°. In the crystal, pairs of N-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric dimers, which are further connected via N-H⋯O hydrogen bonds into a chain running along [01].
In the title coordination polymer, {[Na(2)(C(8)H(7)O(3))(H(2)O)(4)](C(8)H(7)O(3))}(n), all the non-H atoms except the water O atoms lie on a crystallographic mirror plane. One sodium cation is bonded to four water O atoms and one vanillinate O atom in a distorted square-based pyramidal arrangement; the other Na(+) ion is six-coordinated by four water O(More)
In the crystal structure of the title compound, C(9)H(8)BrNO(3)S, the thia-zine ring is in the twisted form. In the crystal, pairs of inter-molecular C-H⋯O hydrogen bonds form inversion dimers with an R(2) (2)(8) ring motif. Weak inter-molecular C-H⋯Br and C-H⋯π inter-actions are also present.
