Objective To compare the clinical efficacy of ear drops containing acetic acid, corticosteroid and acetic acid, and steroid and antibiotic in acute otitis externa in primary care. Design Randomised controlled trial. Setting 79 general practices, Netherlands. Participants 213 adults with acute otitis externa. Main outcome measures Primary outcome: duration of symptoms (days) according to patient...
Nowadays, vinegar is industrially produced by mesophilic acetic acid bacteria (AAB). However, temperature fluctuation during acetous fermentation is inevitable, and may cause process disturbances. This can be mostly avoided using thermo-tolerant AAB. The main purpose of the present study was to isolate thermo-tolerant AAB. Fermentation performances were then evaluated. Twenty-eight different is...
Callus cultures were induced from leaf segments of Cephaelis ipecacuanha on modified gamborg medium containing 2,4 - dichlorophenoxy acetic acid (2mg/1) Indole acetic acid (1mg/1), kinetin (1mg/1) and sucrose (20g/1). The biogenetic profile for alkaloids was established. The established callus cultures were transferred to modified gamborg medium supplemented with L- DOPA (40 mg/1) and L methion...
since its introduction in 1959, translation quality assessment (tqa) has been among the most addressed research topics in translation studies. during recent years, there has been a crucial increase on the study of tqa. various methods have come on scene. although these methods are based on scientific theories, most of them have remained at the level of theory. juliane house’s model is among tho...
in this thesis, a new optically active poly(amide-imide) (pai) was synthesized by the indirect polycondensation reaction of the l-phenylalanine based diacid chloride and 4,4?-diaminodiphenylether in the presence of triethylamine in n-methyl-2-pyrrolidone. the formation of pai was confirmed by ftir, 1h nmr and elemental analysis. in next step, the surface of titanium dioxide (tio2) nanoparticles...
bserved by many teachers that most of the time, mumbling and searching for their intended words, students complain why they have forgotten the words they have learned in the previous semesters. they ask for some new ways that may help them to recall and apply the learned words more efficiently, since as they declare one of the most important skills in foreign language learning is having a g...
a novel and ultra low cost isfet electrode and measurement system was designed for isfet application and detection of hydronium, hydrazinium and potassium ions. also, a measuring setup containing appropriate circuits, suitable analyzer (advantech board), de noise reduction elements, cooling system and pc was used for controlling the isfet electrode and various characteristic measurements. the t...
In this study, Microwave-Assisted Solvent Extraction (MASE) was used to recover oil residues from pomace olive using acidic hexane. Results obtained demonstrated that oil extraction yield increased with time, the amount of acetic acid in hexane and power radiation. For both radiation powers used (170 and 510W), the optimal extraction time and most interesting content of acetic acid in hexan...
Linear increments in ferulic acid concentration produce logarithmic increases in the ferulic acid-induced lag periods prior to the peroxidase-catalyzed oxidation of indole-3-acetic acid in a system containing 2,4-dichlorophenol and MnCl(2) in acetate buffer at pH 5.6. Maintaining the ratio of indole-3-acetic acid to ferulic acid constant at 100 while linearly raising the ferulic acid concentrat...
