Histological, Histochemical and Amino Acid Profile Study of the Cervical Esophagus in the Iraqi Pin-Tailed Sandgrouse (Pterocles alchata) and Red-Wattled Lapwing (Vanellus indicus)
...Show More Authors

The avian esophagus shows structural and functional differences related to feeding habits and habitat, with mucous secretions and amino acids playing key roles in protection and metabolism. The present study aimed to comparatively investigate the histological, histochemical, and amino acid profile characteristics of the cervical esophagus in the Iraqi pin-tailed sandgrouse (Pterocles alchata) and the red-wattled lapwing (Vanellus indicus). A total of eight adult individuals from each bird species (sandgrouse and lapwing) were collected from the Al-Samawah Desert, Al-Muthanna Province, and AlYusufiyah District, Baghdad Governorate, Iraq, respectively, between October 2025 and January 2026. Histological examination was performed using hematoxylin and eosin (H&E), Masson’s trichrome, periodic acid–Schiff (PAS), and Alcian blue (AB, pH 2.5) stains. Amino acid profiles of cervical esophageal tissues were analyzed using highperformance liquid chromatography (HPLC). The histological results demonstrated that the cervical esophagus in both bird species consisted of three main layers: tunica mucosa, tunica muscularis, and tunica adventitia, while the tunica submucosa and muscularis mucosae were absent. The mucosa was lined by non-keratinized stratified squamous epithelium supported by a collagen-rich lamina propria. In the Iraqi pin-tailed sandgrouse, the esophageal glands were located mainly within the lamina propria, whereas in the red-wattled lapwing, they appeared as intraepithelial glands. Histochemical staining revealed strong PAS reactivity and moderate AB reactivity in the mucous secretions of both bird species, indicating the presence of neutral and acidic mucopolysaccharide. The HPLC analysis identified 18 amino acids in the cervical esophageal tissues of both species. Glutamine showed the highest concentration, whereas methionine exhibited the lowest concentration in both birds. Most amino acids did not differ significantly between the two species (p > 0.05). However, glutamic acid showed a significant increase in the Iraqi pin-tailed sandgrouse compared with the red-wattled lapwing (p ≤ 0.05). The present findings suggest that the cervical esophagi of both bird species may exhibit structural and biochemical adaptations associated with feeding habits and ecological conditions

Analysis of X-ray diffraction lines profile of Tio2 nanoparticles to determine the energy per unit volume and stress by using Halder-Wagner method
...Show More Authors

In this study, the Halder-Wagner method was used for an analysisX-ray lines of Tio2 nanoparticles. Where the software was used to calculate the FWHM and integral breath (β) to calculate the area under the curve for each of the lines of diffraction. After that, the general equation of the halder- Wagner method is applied to calculate the volume (D), strain (ε), stress (σ), and energy per unit(u). Volume (β). Where the value of the crystal volume was equal to (0.16149870 nm) and the strain was equal to (1.044126), stress (181.678 N / m2), and energy per unit volume (94.8474 J m-3).The results obtained from these methods were then compared with those obtained from each of the new paradigm of the HalderWagner method, the Shearer developm

Copolymerazaion of N-vinyl-2-pyrrolidon with Acrylic Acid and Methylmethacrylate
...Show More Authors

Low conversion copolymerization of N-vinyl-2-pyrrolidon M.W = (111.14) VP (monomer-1) has been conducted with acrylic acid AA and methymethacrylate MMA in ethanol at 70ºC , using Benzoyl peroxide BPO as initiator . The copolymer composition has been determined by elemental analysis. The monomer reactivity ratios have been calculated by the Kelen-Tudos and Finman-Ross graphical procedures . The derived reactivity ratios (r1 , r2 ) are : (0.51 , 4.85) for (VP / AA ) systems and (0.34 , 7.58) for (VP , MMA) systems , and found the reactivity ratios of the monomer AA , MMA is mor than the monomer VP in the copolymerization of (VP / AA) and (VP /MMA) systems respectly . The reactivity ratios values were used for microstructures calculation.

The research deals with analyzing the influencing role of trade policies in the growth and development of productive economic sectors and their contribution to GDP and its reflection on workforce employment. Studies have proven the success of the Malaysian experience in stimulating the productive economic sectors to grow and their contribution to the gross domestic product with an increase in the growth of local markets and access to international markets for national products. The research also deals with the ineffectiveness of Iraqi trade policies after 2003 in stimulating the productive economic sectors (agricultural and industrial) on economic growth, as most of the increase in Iraqi GDP growth throughout the study period was

Background: Controversy exists concerning the presence and amount of the Bennett mandibular immediate side shift among patients and whether it is necessary to accommodate for it in adjustable articulators. The aim of this study was to register and calculate the amount of any immediate side shift (ISS) present in patients requiring full mouth rehabilitation. Materials and methods: 3- dimensional condylar movements of 50 Iraqi TMD-free patients were recorded using a stereographic fully adjustable articulator system during protrusion, left and right eccentric mandibular movements. Protrusive angles of each patient were verified to figure out the suitable fossa analog for each case. The thickness of each right and left premade fossa analog sele

A Comparative Study of the Influence of Different Types of Polymers on Viscosity Index and Pour Point of Iraqi Base Oils
...Show More Authors

In this study, the effects of blending the un-branched acrylate polymer known as Poly (n-decyl acrylate), and the branched acrylate polymer known as Poly (iso-octyl acrylate), on the viscosity index (VI), and the pour point of the Iraqi base stocks 40, and 60 respectively, were investigated. Toluene was used as a carrier solvent for both polymer types. The improvement level of oils (VI, & pour point) gained by blending the oil with the acrylate derived polymers was compared with the values of (VI, and pour point) gained by blending the oil with a commercial viscosity index, and pour point improver. The commercial lubricant additive was purchased and used by Al-Daura Refineries. It consisted of an un-known olefin copolymer dissolved i
