A part two of Accipitridae Family members that belong to three genera: Circus, Gyps, and Neophron were documented as morphometrics, distribution ranges, and conservation status were reviewed and comprehensively discussed. A total of 29 voucher specimens belong to six species which are conserved in the "Iraq Natural History Research Center and Museum INHM" as follow: Marsh Harrier Circus aeruginosus (Linnaeus, 1758), Hen Harrier Circus cyaneus (Linnaeus, 1766), Montagus Harrier Circus pygargus (Linnaeus, 1758), Pallid Harrier Circus macrourus (Gmelin, 1770), Egyptian vulture Neophron percnopterus (Linnaeus, 1758), and Griffon vulture Gyps fulfus (Hablitz, 1783). The results revealed significant criteria about near threatened NT species IUCN and Birdlife International listed as Pallid Harrier Circus macrourus, and Endangered (EN) species as Egyptian vulture Neophron percnopterus globally decreasing population trend.

The azo-coupling of AMX and DOX with the color reagent in the alkaline medium caused yellow and yellow-orange azo dyes with maximum absorption wavelengths of 435 and 438 nm, respectively. The UV-Vis spectroscopy was utilized to determine the target analyte after the extraction procedure.

Here, we developed a batch spectrophotometric method and a method employing a paper-based microfluidic device for the estimation of Amoxicillin (AMX) in pure solution and pharmaceutical preparations. The detection depends on the coupling reaction of Amoxicillin with diazotized sulfadimidine (DSDM) in an alkaline medium.

Here, we report on the development of two colorimetric analysis methods for the study the antibiotic doxycycline hyclate (DOX) and the nasal decongestant oxymetazoline hydrochloride (OXY), in solution as well as in their respective formulations. We compare a UV/vis spectrophotometry method with a color change recorded on a microfluidic paper-based analytical device (μPAD).

A hollow fiber liquid phase microextraction (HF-LPME) in conjunction with reversed phase HPLC-UV method was developed for the extraction and determination of trace amounts of the antidiabetic drug, mitiglinide (MIT) in biological fluids. The drug was extracted from 10 mL aqueous sample (donor phase (DP)) into an organic phase impregnated in the pores of hollow fiber, followed by the back extraction into a second aqueous solution (acceptor phase (AP)) located in the lumen of the hollow fiber. Parameters influencing the extraction efficiency including the kind of organic solvent, composition of DP and AP, extraction time, stirring rate and salt addition were investigated and optimized.
