In this paper Zener diode was manufactured using ZnO-CuO-ZnO/Si heterojunction structure that used laser induced plasma technique to prepare the nanofilms. Six samples were prepared with a different number of laser pulses, started with 200 to 600 pulses on ZnO tablet with fixed the number of laser pulses on CuO tablet at 300 pulses. The pulse energy of laser deposited was 900mJ using ZnO tablet and 600mJ using CuO tablet. All prepared films shown good behavior as Zener diode when using porous silicon as substrate.
Micromorphological characters of petals in 8 genera representing 12 taxa of Bignoniaceae from Egypt were carried out using scanning electron microscopy (SEM) to evaluate their taxonomic importance in petal epidermal micromorphology, including epidermal cell types (areolate, papillose conical, and areolate mixed with papillose conical), trichome types (non-glandular; funnel shape, flexible and stiff-bristly, and glandular; peltate, capitate, cupular, stipitate, and patelli-form), trichome ornamentation (striate, verucate, and smooth, and stomata on both the abaxial and adaxial surfaces. Stomata are present in all species except Jacaranda acutifolia Humb. & Bonpl., 1806 and Markhamia zanzibarica (Bojer ex DC.) K. Schum., 1895. We used

... Show MoreThyroid hemiagenesis (THA) is a rare congenital anomaly in which one lobe of thyroid gland fails to develop during embryological stage. Agenesis may be unilateral, total or isthmic. Left thyroid lobe is more commonly involved than right lobe in hemiagenesis. Agenesis of the isthmus was seen in 50% of cases. Left sided hemiagenesis is more common than right sided hemiagenesis with a Left to right ratio of 4:1. Clinically patients can be euthyroid, hypothyroid or hyperthyroid. Often it is diagnosed as an incidental finding during ultrasonography (USG) study of neck, which can easily diagnose this condition.

This study examines the Al-Ashaali drainage basin, a watershed in the southern Iraqi desert,
which constitutes a hydro-geomorphological system within the lower valleys region according
to Iraq's geomorphological classification. The study uses a digital elevation model to classify
the landforms of the watershed. Landform maps from the Shuttle Radar Topography Mission
(SRTM) were combined with topographic maps to understand the formation of landforms.
Geospatial simulation models were developed to create a simplified geomorphological base
map. The data was analyzed utilizing ArcGIS software, which included color mapping tools,
topographic maps, as well as geological and hydrological maps. The study aims to enhance

We examined morphological variations in Carabus granulatus L., 1758 (Coleoptera,
Carabidae) populations across different habitats in the Kaluga Region. Discriminant analysis
revealed subtle but significant morphological differences between populations, with pronotum
length being the key discriminating trait. Morphological variability was primarily driven by
historical microevolutionary processes rather than direct phenotypic adaptation to specific
habitats. Local ecological factors, such as microclimate and resource availability, had a
greater influence on morphometric traits than the general habitat type. Populations in the
eastern part of the Kaluga Region exhibited smaller body sizes due to intensive forest use.
A survey and identification were made of edible mushrooms from Salah Al Din Province,
central of Iraq, were conducted. The species were identified according to macroscopic
characteristics, such as the size, shape, color, and surface texture of the cap; the color of the
gills and their attachment to the stipe, if any, the number of pores per millimeter; and the color,
size , and surface texture of the stipe. Other features noted included the presence or absence
of the annulus and volva; Microscopic characteristics were also examined, including the size
of the basidium and the number of its spores; the color, size, and shape of the spores; the size,
shape, and type of cystidia, and whether cystidia were present or abse
Birds are exposed to infection by various ectoparasites, including chewing lice (Order:
Phthiraptera), which affect nearly all avian species. The present study aimed to diagnose the
species of lice parasitizing poultry using morphological traits, and molecular analysis (PCR).
Additionally, the study included the construction of a phylogenetic tree of the among the
species sequenced on the basis of genetic sequencing by using 18S rRNA. The survey was
conducted during the period from November 2023 to October 2024. A total of 300 chickens
and pigeons were examined from different locations in Basrah Province. In the study, four
species were recorded, and registered in GenBank with the following accession numbers:

The primary aim of this investigation is to update the taxonomy of the genus Paeonia
L.,1753 (Paeoniaceae) in Iraq based on morphological characteristics, anatomical features,
ecological notes, and geographic distribution using, geographic information systems (GIS).
The results showed that the genus in Iraq contains only one subspecies, P. mascula subsp.
mascula (L.) Mill.,1768 a perennial herbs less than 80 cm tall with ascending, cylindrical,
glabrous stems, showy flowers, and underground carrot-shaped tuber roots. Anatomical
analysis reveals anomocytic stomata with an elliptical or rectangular apparatus, a
hypostomatic leaf, a stomatal index of 26.2%, and a stomatal density of 51 per mm2. A crosssection

The taxonomic features of the Casuarinaceae family were carefully examined to determine
which characters were most trustworthy for taxonomic delimitation. Morphological
characteristics that represented habit, leaf teeth, article, phyllichnia, male spike, female cone,

present, among which four species belonged to the genus Casuarina L., 1759. On the other
hand, herbarium studies identified the previous record of three species belonging to the genus

The humid and warm conditions in greenhouses provide an excellent environment for
pests’ living conditions, and therefore, they provide ideal medium for alien introductions.
Molluscs are among the most significant pests that infest plastic covered greenhouses. To
identify and report their mollusc species, 23 greenhouses in Iraq were surveyed between
March 2023 and April 2024. Of these, 11 were found to be infested with snails. A total of 158
specimens were collected and morphologically identified to seven species: Monacha
obstructa (L. Pfeiffer, 1842), Eobania vermiculata (O.F. Müller, 1774), Xeropicta krynickii
(Krynicki, 1833), Rumina decollata (Linnaeus, 1758), Polygyra cereolus (Megerle Von

pratylenchid nematode Pratylenchus goodeyi Sher and Allen, 1953 (Family, Pratylenchidae).
They were illustrated by molecular aspects. All specimens of both genera were cultured and
reproduced for DNA extraction. M. franseni (IRQ.ZAh2 PP528819.1 isolate) was
characterized. P. goodeyi (IRQ.ZAh5 PP535537 isolate) was also characterized. Selected
specimens of these two species were molecularly characterized using the partial ITS-rRNA
gene sequences. The ITS-rRNA sequence of IRQ.ZAh2 PP528819.1 isolate had a range of
(98.62%-100%) sequence homology with ITS-rRNA sequence of M. franseni available in

The aim of the current investigation is to study the embryogenesis of the pseudobranchia
(PB) in the Eastern mosquito fish Gambusia holbrooki, Girard, 1859 (Cyprinodontiformes,
Poeciliidae). Histological sections from 2-4 mm long embryos revealed the presumable PB as
a cell mass surrounded by a row of squamous cells in the operculum, as well as the formation
of cartilage and blood vessels, and the beginning of the formation of its lamellae. In 5-7.75
mm long embryos, a prominent rise appeared in the mass of cells and PB lamellae, along with
an increase in melanin deposition around the blood vessels. Moreover, a row of squamous
cells encircled the rise from the front and back. At this stage, the parallel arrangement o

The current study aimed to identify the morphological, histological, and histochemical
composition of the proventriculus and the gizzard of the slender-billed gull Chroicocephalus
genei (Breme, 1839) (Aves, Charadriiformes, Laridae) using a light microscope.
Morphological analysis revealed that the stomach of the bird is divided into proventriculus
and gizzard. The proventriculus is situated to the left of the body's midline and is completely
encompassed by the liver's left lobe, and appears pear-shaped or elongated oval and has
smooth walls. The gizzard has a pear-shaped muscular organ and is located to the left of the
midline in the lower quarter of the abdominal cavity. The results of histological examination
