Morphological and Molecular Identification of Limnodrilus Claparede,1862 Species(clitellata: naiDIDAE) IN Tigris River, Baghdad/Iraq
...Show More Authors

Sludge worm samples were collected from the Tigers River sediment during the period from November 2018 to June 2019 in Al Sarafiya District/ Baghdad- Iraq. Biometric morphological measurements focusing on the form of penis sheath and chaetal morphology were used for species identification, in addition to molecular analysis by amplification of conserved 18s rRNA encoding gene using ITS1 and ITS4 universal primers.According to the morphological measurement records, the results revealed the existence of Limnodrilus hoffmeisteri Claparede 1862, L. claparedeianus Ratzel, 1868 and L. cervix Brinkhurst 1963. Other two groups of specimens, with short penis sheath, were identified by molecular technology as L. hoffmeisteri complex, and L. claparedeianus.-cervix. Both species were considered as new record for Iraqi fauna, and had been registered in NCBI under the accession number LC497073 and LC497074 respectively

According to the morphological measurements records, the results revealed the existence of Limnodrilus hoffmeisteri Claparede 1862, L. claparedeianus Ratzel, 1868 and L. cervix Brinkhurst 1963, which identified by molecular analysis using 18S rRNA gene and DNA sequencing recorded  L. hoffmeisteri complex, This species is a new record in Iraq, and has been registered in NCBI under the accession number LC497073. There was also specimen identified by molecular analysis using 18S rRNA gene and DNA sequencing recorded L. Claparedeianus –cervix. Also, this species is a new record in Iraq, and has been registered in NCBI under the accession number LC497074.

*Part of M.Sc. Thesis of Research

Sludge worms samples were collected from the Tigers River sediment in Al Sarafiya district, / Baghdad- Iraq. Biometric morphological measurement focusing on the form of penis sheath and chaetal morphology, in addition to molecular analysis using 18s rRNA gene, were used for species identification.

According to the morphological measurements records, the results revealed the existence of two groups of Limnodrilus hoffmeisteri Claparède 1862 Individuals have long penis sheath with distal end with symmetrical or asymmetrical hood, while other individuals with short penis sheath with circular plate- like hood, which identified by molecular analysis as L. hoffmeisteri complex, and the isolate 18S rRNA  recorded with the accession number LC497073

Two groups of very long penis sheath identified as L. claparedeianus Ratzel, 1868, and L. cervix Brinkhurst 1963, with dorsal and ventral projections.  There are also a group of specimens with short penis sheath, which identified by molecular techniques as L. Claparedeianus –cervix 18S rRNA encoding genomic sequence was resented to the NCBI, recorded with the accession number LC497074.  Limnodrilus hoffmeisteri complex and L. claparedeianus – cervix were considered as new records for Iraq.

The effect of the photomagnetic poles strategy on learning the skill of spiking in volleyball
...Show More Authors

Objective: preparing educational units for the magnet poles strategy in learning the spiking skill in volleyball, and identifying the effect of the magnet poles strategy in learning the spiking skill in volleyball for female students.Research methodology: The experimental design with two equal experimental and control groups with tight control was also adopted in the pre- and post-tests. The boundaries of this research community are represented by fourth-grade middle school students at Basra Girls' Middle School (2024-2025), whose total number is (90) students, distributed by nature into 4 sections. Sections (A-B) were determined by lottery, so that Section (A) represents the experimental group and Section (B) represents the control

The Role of Project Health Check Reports in Identifying Indicative Factors of a Troubled Project
...Show More Authors

Government-sponsored projects in Iraq significantly improve the economic situation and provide services but face high rates of troubling blocks. This work aims to identify indicative factors of the Troubled Project using periodic health check reports based on a literature review and interviews with Iraqi experts. As a result, a questionnaire was prepared that included four sections. The first is personal information; the second section is information about knowing the level of institutions’ implementation of project management through prepared documents. The third section is about indicative factors for the project's trouble, including 25 workers; the fourth section is about the questions in the periodic reports to che

Impact of Sulfate in the Sand on the Compressive Strength of Metakaolin-Based Geopolymer Mortar
...Show More Authors

The advancement of cement alternatives in the construction materials industry is fundamental to sustainable development. Geopolymer is the optimal substitute for ordinary Portland cement, which produces 80% less CO2 emissions than ordinary Portland cement. Metakaolin was used as one of the raw materials in the geopolymerization process. This research examines the influence of three different percentages of sulfate (0.00038, 1.532, and 16.24) % in sand per molarity of NaOH on the compressive strength of metakaolin-based geopolymer mortar (MK-GPM). Samples were prepared with two different molarities (8M and 12M) and cured at room temperature. The best compressive strength value (56.98MPa) was recorded with 12M w

Evaluating the Uses of Concrete Demolishing Waste in improving the Geotechnical Properties of Expansive Soil
...Show More Authors

Expansive soil is one of the most serious problems that face engineers during the execution of any infrastructure projects. Soil stabilization using chemical admixture is one of the most traditional and widespread methods of soil improvement. Nevertheless, soil improvement on site is one of the most economical solutions for many engineering applications. Using construction and demolishing waste in soil stabilization is still under research., The aim of this study is to identify the effect of using concrete demolishing waste (CDW) in soil stabilization. Serious tests were conducted to investigate the changes in the geotechnical properties of the natural soil stabilized with CDW. From the results, it is concluded that the

Stimulation of Hatching Efficiency in Capsulated Cysts of Artemia fransiscana Using 890 nm Diode Laser
...Show More Authors

Artemia fransiscana is one of the most important live food for commercial larval aquaculture. The aim of this study is to investigate the effects of 890 nm diode laser irradiation on Artemia capsulated cysts using (1-10) minutes exposure time, and 2.26x10-3 J/cm2 Fluence. The Artemia samples were obtained from two locations: Dyalaa and Basraa. After irradiation, hatching percentage (H %) and hatching efficiency(HE) of Artemia were measured after 24 and 48 hours of incubation. The results of the effect of laser light on the capsulated cysts from Dyalaa showed that the optimum dose for enhancing (H %) after 24 hours of incubation is using 10 minutes exposure time, while after 48 hours of incubation the (H %) enhancement can be achieved

Impact of Helicobacter pylori in some Blood Parameters Change of Iraqi Patients with Gastritis Disease
...Show More Authors

In order to find the relationship between Helicobacter pylori infection and hematological disease are disorders which primarily affect the blood and blood-forming organs. One hundred and three blood samples were taken for people aged (20-68) years for the period from 10/1/2021 to 1/3/2022, divided into three groups. The first group included 44-person H. pylori-infected with symptoms of infection, the second group had 19-person H. pylori-infected but without symptoms, and the third group included 40 people without H. pylori infection. All studied groups were carried out to measure anti-IgG Ab, Vac A and Ferritin by Enzyme Linked Immunosorbent Assay (ELISA) technique. The statistical analysis indicates a non-significant difference in Vac A (p

Background: Nanotechnology represents a new science that promises to provide a broad range of uses and improved technologies for biological and biomedical applications. One of the reasons behind the intense interest is that nanotechnology permits synthesis of materials that have structure is less than 100 nanometers. The present work revealed the effect of zinc oxide nanoparticles (ZnO NPs) on Streptococcus mutans of Human Saliva in comparison to de-ionized water. Materials and methods: Streptococcus mutans were isolated from saliva of forty eight volunteers of both sexes their age range between 18-22 years and then purified and diagnosed according to morphological characteristic and biochemical tests. Different concentrations of ZnO NPs w
