(Elsevier B.V., 2019)
In this study, two novel Schiff base ligands (L1 and L2) derived from condensation of methyl 2-amino-6-methyl-4,5,6,7-tetrahydrothieno[2,3-c]pyridine-3-carboxylate and methyl 2-amino-6-phenyl-4,5,6,7-tetrahydrobenzo[b]th ...
Determination of biogenic amines at low μg L–1levels as acetylacetone derivatives by RP-HPLC with UV-visible detection in expired apple juice samples
(Slovensko Kemijsko Drustvo, 2018)
An accurate and sensitive method for trace quantification of three biogenic amines in expired apple juice samples based on reversed-phase liquid chromatography (RP-HPLC) with UV-visible detection is described. Biogenic ...
Comparison of three-dimensional facial morphology between upright and supine positions employing three-dimensional scanner from live subjects
(Elsevier B.V., 2017)
Facial soft tissue thicknesses (FSTT) measurements collected from Magnetic Resonance Imaging (MRI) and Computed Tomography (CT) imaging techniques are most commonly taken in the supine position for forensic craniofacial ...
Spectrophotometric determination of acidity constants of some macrolides in acetonitrile-water binary mixtures
(2010)
The acidity constants of eight macrolides (erythromycin, roxithromycin, oleandomycin, azithromycin, josamycin, tylosin tartrate, tilmicosin and spiramycin) have been determined in acetonitrile-water binary mixtures (30%, ...
Boric acid complexes with thiamine (vitamin B1) and pyridoxine (vitamin B6)
(2014)
Complexation of boric acid with vitamins B1 (thiamine) and B6 (pyridoxine) was investigated. The products were isolated from aqueous solutions and characterized by elemental analysis, FT-IR, 13C MAS NMR and thermal methods. ...
Antimicrobial activity and chemical composition of coriander & galangal essential oil
(Association of Pharmaceutical Teachers of India, 2017)
Essential oils were obtained from Coriandrum sativum and Alpinia officinarum through steam distillation method in this study. Antimicrobial activities of the obtained essential oils were investigated by using minimum ...
