Oral pyogenic granuloma (PG) is a benign but very vascular lesion that causes discomfort and bleeding.
Conventional surgical excision is effective but has a high recurrence rate and postoperative pain. Diode laser
excision is a less invasive procedure that offers precise tissue removal and better hemostasis. Our Objective is to
evaluate the safety and efficacy of diode laser excision for the treatment of oral pyogenic granuloma. A total of
sixteen patients (mean age 39.3; age range 15 - 74 years; 11 males and 5 females) with de novo oral PG were
enrolled and all lesions were removed under local anesthesia using a continuous 1.5 W 980 nm diode laser with
minimal bleeding, without the need for sutures and a 0.

Laser scribing of the front-layer metal contact in thin-film silicon solar cell is one method that
enhances optical absorption through localized surface plasmon resonance (LSPR) induced at the laser-scribed
gold nano-grooves. A new approach investigates both the plasmonic effect and increasing the absorption of the
gold via laser scribing to improve the cell performance. A 3D ultra- thin film silicon solar cell (dimensions of
400 × 400 × 900 nm3 for width, length, and height) was designed, with a 50 nm thick gold front contact scribed
at groove depths of 10, 20, 30, and 40 nm (fixed width of 100 nm). COMSOL Multiphysics software version
6.2, using the finite element method (FEM), was employed to design and

This study investigates the structural and optical properties of Fe-doped (CuO: ZnO) thin films with varying Fe contents (x = 0.1–0.5%) deposited on glass substrates via pulsed laser deposition (PLD) at ambient temperature under a vacuum of 1 × 10⁻² mbar. X-ray diffraction (XRD) confirmed that all films maintained a monoclinic polycrystalline structure, with grain size decreasing with increasing Fe concentration. Energy Dispersive X-ray Spectroscopy (EDS) verified the successful incorporation of Fe without altering the Cu and Zn composition. Increasing Fe concentration significantly affected the optical transmission, absorption, refractive index (n), extinction coefficient (k), and dielectric constants, demonstrating that Fe doping

تعد الأحداث الدولية والإنسانية المعاصرة محطات حاسمة في تطور القانون الدولي، حيث أثرت الصناديق الدولية في إعادة تشكيل العديد من المفاهيم القانونية والسياسية، فقد أدت الممارسات الدولية إلى بلورة مفاهيم جديدة، خاصة فيما يتعلق بتدويل حقوق الإنسان، ومع تزايد استهداف المدنيين في النزاعات المسلحة وارتكاب الجرائم ضد الفئات المستضعفة، أصبح من الضروري إعادة النظر في سيادة الدول التقليدية التي تحد من التدخل في الش

The development of low-cost, efficient, and environmentally friendly adsorbents capable of simultaneously removing both heavy metals and synthetic dyes from wastewater remains a critical challenge in environmental remediation. In this study, a novel chitosan/pumice (CS/PM) composite was synthesized and evaluated for its multifunctional adsorption performance toward four common and toxic pollutants: lead (Pb(II)), cadmium (Cd(II)), methylene blue (MB), and Congo red (CR). Characterization confirmed the successful integration of chitosan with pumice, resulting in reduced crystallinity, enhanced thermal stability, and active functional groups involved in adsorption. Adsorption experiments demonstrated optimal pollutant removal at a pH value of

The increasing discharge of dye-containing wastewater has become a serious environmental problem, requiring efficient and sustainable treatment technologies. In this study, poultry litter–derived biochar (BC) was prepared via pyrolysis at 550 °C and subsequently modified with chitosan to produce a composite adsorbent (BC/CS) for the removal of Congo Red (CR) from aqueous solutions. The materials were characterized using SEM, BET, XRD, FTIR, and XPS analyses. BET results showed that chitosan modification slightly decreased the specific surface area from 8.28 to 8.18 m²/g and pore volume from 0.035 to 0.030 cm³ /g, while introducing abundant amine and hydroxyl functional groups on the surface. Maximum adsorption occurred at pH 3, w

In this study, reduced graphene oxide (rGO) was synthesized from graphene oxide (GO) via an ascorbic acid-assisted reduction process. GO was synthesized from graphite powder using a modified Hummers technique. The surface morphology, structure, functional groups, and elemental compositions of the produced materials were studied using various methods, such as scanning electron microscopy (SEM)/EDX, X-ray diffraction (XRD), atomic force microscopy (AFM), Fourier transform infrared (FTIR), and UV-Vis. The removal of oxygen-containing functional groups in rGO through reduction resulted in poor sample quality. In addition, FTIR investigations revealed that GO contained more oxygen-containing functional groups than rGO. Typical peaks at 2

Objectives Acid sphingomyelinase deficiency (ASMD) is an inherited autosomal recessive disease caused by pathogenic variants in the sphingomyelin phosphodiesterase-1 (SMPD1) gene, which encodes acid sphingomyelinase (ASM). ASMD has 3 broad phenotypes (type A, type A/B, and type B) characterized by the age of onset, symptomatology, and the rapidity of disease progression. The diagnosis of ASMD can be delayed or missed because of the wide spectrum of severity and its variable manifestations. Analysis of genotype-phenotype correlations can help to determine ASMD disease type and inform management. Here, we describe the clinical presentation of 47 patients with ASMD referred to a single center in Iraq since 2007, whose diagnosis was confirmed b

Modern societies tend to live in an electronic way. Indeed, many citizens and business owners are currently working in an electronic way because the use of information technology systems reduces the number of steps in the routine required to carry out work, and converts manual jobs to automatic, and helps improve the way of serving citizens by providing access to information in a service manner. The e-government can also automate responses to requests for licenses or information, in order to save time and energy for employees in order to provide better services to those reviewers who call directly or attend by themselves to accomplish some exceptional work. Therefore, to raise awareness its services, it is necessary to use various public re

Dr Oluwole Ojewale, a scholar and Sahel expert based in Dakar, explores the implications of the recent Benin coup attempt for the region, the history of intervention by the Economic Community of West African States and its complicated relationship with the recently formed Alliance of Sahel States. Cooperation, even now military-led states in the Sahel, is key to stopping the descent of coups in West Africa he argues. “The region must revitalize security cooperation, even with the AES states. Isolation breeds insecurity. Niger’s withdrawal from counterterrorism coordination has created openings exploited by criminal networks and extremist groups, especially along porous borders with Nigeria and Benin,” Ojewale writes. “Without renewe

Magnesium Phthalocyanine (MgPc) was deposited on a glass substrate by pulsed laser deposition (PLD) using Q-Switching Nd:YAG laser with wavelength 1064 nm, repetition rate 6 Hz, at room temperature (300K) and different annealing temperatures (373, 473, and 573)K under vacuum condition of 10-3 torr. All films were annealed for one hour to attain crystallinity. X-ray diffraction (XRD) of MgPc powder indicated that MgPc crystallizes in polycrystalline with a monoclinic structure. While comparing the MgPc films, it was observed that the intensity of the characteristic peak increases with temperature, and the crystallization exhibited a monoclinic structure typical of the β-form. The Miller indices, hkl, values for each diffraction peak

Gundelia, a genus of flowering plants native to the Mediterranean region, particularly in Iraq, holds promise as a sustainable adsorbent for the treatment of dye-polluted water. This study explores the potential of Gundelia seeds (GS) waste as a biobased adsorbent for removing methylene blue dye from synthesized wastewater. Utilizing various analytical techniques, including scanning electron microscopy (SEM), Fourier transform infrared (FTIR) spectroscopy, and X-ray diffraction analysis (XRD), we assessed GS as an active adsorbent with performance comparable to fabricated and expensive composites. Key parameters such as pH (3-11), pH at the point of zero charge, temperature (298-328 K), dose (0.02-0.1 g), dye concentration (10-50 ppm), and

COVID-19 was declared a pandemic by the World Health Organization in March 2020, and the SARS-CoV-2 virus continues to be a global concern with new variants. Our research focused on the relationship between COVID-19 and air pollution, and we included findings from recently published research. In summary, there is a direct relationship between air pollution and COVID-19 infection and fatality rates. This relationship was evident after many parts of the world declared lockdowns. Research to understand the relationship between infection rates and air pollutants identified indirect factors that contributed to the spread of infection. In this article, we explore studies on air pollutants, the use of face masks, weather conditions, short-

This paper reports the synthesis and use of a novel metal-organic framework (MOF), named Zr-BADS, within the thin-film nanocomposite (TFN) membranes for reverse osmosis (RO) applications. Two types of zirconium-based MOFs, Zr-BADS-1 and Zr-BADS-2, were synthesized via a solvothermal method using bicinchoninic acid disodium salt as a linker and either dimethylformamide or ethanol as solvent, respectively. TFN membranes were prepared by embedding these MOFs within the polyamide thin film supported by a polysulfone support sheet. The specific surface area of Zr-BADS-1 and Zr-BADS-2 was determined to be 396.1 and 278.6 m2/g, respectively, indicating significant surface area conducive to water permeation. Scanning electron microscopic analysis r

This study proposes a pioneering Ethical Artificial Intelligence (EAI) framework for advancing sustainable development in Iraq by integrating eight multidimensional sustainability indicators—administrative, technological, economic, environmental, social, legal, security, and governance. Utilizing data from 60 completed development projects, the framework combines SPSS statistical analysis, the SMART-AI model, and Artificial Neural Networks (ANN) to identify key determinants of project success and failure. Results reveal a 37% project failure rate, with administrative and technological deficiencies emerging as the most influential predictors. The SMART-AI model achieved an accuracy of 91.3% using stratified k-fold cross-validation. A bilin
