results intraclass correlation coefficient for left and right showed good to high reliability for the cross sectional area of lumbar multifidi (0.74 and 0.88, respectively) as well as the anterior-posterior dimensions of lumbar multifidi (0.89 and 0.91, respectively) and transverse abdomini thickness (0.73 and 0.85, respectively). conclusions rehabilitative ultrasonography is a reliable and non...
conclusions it is suggested to consider practical programs to maintain religious believes in students. materials and methods this was a descriptive analytic study. study population was 370 students selected by census sampling from all students of this faculty. gathering data tools were religious attitude questionnaire (golriz and brahani 1974) and life orientation test questionnaire (lot-r). re...
Two earlier crystal structure predictions (CSP) of aminophenol compounds are checked against experimental structure determinations. One of the predictions classified originally as ‘‘good’’ is verified and is now seen to be somewhat correct. The other prediction, which was classified earlier as ‘‘unclear’’, is incorrect. The two experimental crystal structures are characterized by small and larg...
A 47-year-old woman, after being exposed to nitrobenzene for 17 months, was admitted to hospital because of headache, nausea, cyanosis, and general weakness. Laboratory study revealed, in addition to methaemoglobinaemia, the presence of p-aminophenol as well as p-nitrophenol in the urine. Both compounds gradually disappeared from the urine during the two weeks after she was removed from the tox...
In the present study, a novel series of N-[4-(2-piperidine-1-yl-ethoxy) phenyl]acetamides were synthesized from 4-aminophenol and characterised by IR, H-NMR, Mass spectral studies and elemental analysis. The antimicrobial potency of compounds is tested against variety of fungal and bacterial strains by disc agar diffusion technique. in comparison to to fluconazole and chloramphenicol respective...
In forensic ballistics, gunshot residue (GSR) particles can be detected using screening or presumptive tests which are mainly focused on the chromophoric reaction. Most serve as an initial indication for a investigator at crime scene before instrumental analysis definitive identification. The methods known to convenient, have fast analysis, and minimal preparation. GSR well-known method of dete...
Abstract The introduction of a -NO 2 substituent in o -aminophenol would create an open-unit polymer suitable for different applications. We report the synthesis poly(5-nitro-2-aminophenol) by aniline-catalyzed oxidative polymerization. structure was intensively characterized spectroscopic techniques, elemental analysis, cyclic voltammetry, electrical conductivity and microscopic measurements s...
A novel metal complexes Cu (II), Co Cd Ru (III) from azo ligand 5-((2-(1H-indol-2-yl) ethyl) diazinyl)-2-aminophenol were synthesized by simple substitution of tryptamine with 2-aminophenol. Structures all the newly compounds characterized FT IR, UV-Vis, Mass spectroscopyand elemental analysis. In addition measurements magnetic moments, molar conductance and atomic absorption. Then study their ...
Effects of temperature and solvents on the thermodynamical electronic properties N-acetyl-para-aminophenol (APAP) have been investigated using density functional theory (DFT) time dependent (TD-DFT). Calculated results shows that thermodynamic such as enthalpy (H), entropy (S) specific heat capacity (Cv) are increased by raising (100 K-1200 K) because enhancing intensities molecular vibration. ...
Two new phenylpropanoid glycosides named cuneataside E (1) and cuneataside F (2), were isolated from the aerial parts of Lespedeza cuneata (Dum. Cours.) G. Don, whose structures were E and Z isomer, respectively. Their structures were elucidated on the basis of comprehensive spectroscopic analysis (UV, IR, HR-ESI-MS, 1D and 2D NMR). In in vitro bioassays at 10 μmol/L, compound 1 showed moderate...
