Al Ghamdi, Norah Mohammad,Khan, Muhammad Badruddin International Journal of Computer ScienceNetwork S 2022 International journal of computer science and netw Vol.22 No.4

This research article presents the work that is related to the application of different machine learning based similarity techniques on religious text for identifying similarities and differences among its various translations. The dataset includes 10 different English translations of verses (Arabic: Ayah) of two Surahs (chapters) namely, Al-Humazah and An-Nasr. The quantitative similarity values for different translations for the same verse were calculated by using the cosine similarity and semantic similarity. The corpus went through two series of experiments: before pre-processing and after pre-processing. In order to determine the performance of machine learning based similarities, human annotated similarities between translations of two Surahs (chapters) namely Al-Humazah and An-Nasr were recorded to construct the ground truth. The average difference between the human annotated similarity and the cosine similarity for Surah (chapter) Al-Humazah was found to be 1.38 per verse (ayah) per pair of translation. After pre-processing, the average difference increased to 2.24. Moreover, the average difference between human annotated similarity and semantic similarity for Surah (chapter) Al-Humazah was found to be 0.09 per verse (Ayah) per pair of translation. After pre-processing, it increased to 0.78. For the Surah (chapter) An-Nasr, before preprocessing, the average difference between human annotated similarity and cosine similarity was found to be 1.93 per verse (Ayah), per pair of translation. And. After pre-processing, the average difference further increased to 2.47. The average difference between the human annotated similarity and the semantic similarity for Surah An-Nasr before preprocessing was found to be 0.93 and after pre-processing, it was reduced to 0.87 per verse (ayah) per pair of translation. The results showed that as expected, the semantic similarity was proven to be better measurement indicator for calculation of the word meaning.

In the present work, untreated Iraqi sand with grain sizes varied between 100 and 200 mm was used to produce a colored glass sample that has shielding features against the low gamma-ray energy. Therefore, a weight of 70e60 wt % sand was mixed with 9e14 wt% B2O3, 8e10 wt% Na2O, 4e6 wt% of CaO, 3e6 wt% Al2O3, in addition to 0.3% of Co2O3. After melting and annealing the glass sample, the X-ray diffraction spectrometry was applied to affirm the amorphous phase of the fabricated glass samples. Moreover, the X-ray dispersive energy spectrometry was used to measure the chemical composition, and the MH-300A densimeter was applied to measure the fabricated sample's density. The Makishima-Makinzie model was applied to predict the mechanical properties of the fabricated glass. Besides, the Monte Carlo simulation was used to estimate the fabricated glass sample's radiation shielding capacity in the low-energy region between 22.1 and 160.6 keV. Therefore, the simulated linear attenuation coefficient changed between 10.725 and 0.484 cm1 , raising the gamma-ray energy between 22.1 and 160.6 keV. Also, other shielding parameters such as a half-value layer, pure lead equivalent thickness, and buildup factors were calculated

Synthesis and characterization of novel Cu2O/PVDF nanocomposites for flexible ferroelectric organic electronic memory devices

Farag S. Al-Hazmi,Dago M. de Leeuw,A.A. Al-Ghamdi,F.S. Shokr 한국물리학회 2017 Current Applied Physics Vol.17 No.9

Copper oxide nanoparticles loaded Poly(vinylidene fluoride) (PVDF) nanocomposites, at concentrations from 1 to 9 wt%, were developed by casting technique. The effect of the Cu2O nanoparticles on the structure, thermal, mechanical and dielectric properties of the PVDF were inspected. The scanning electron microscopy (FE-SEM) revealed the well dispersion of the Cu2O nanoparticles into the PVDF matrix up to 5 wt%. The X-ray diffraction (XRD) patterns and the infrared spectroscopy (FTIR) measurements implied that the inclusion of the Cu2O nanoparticles into the PVDF matrix leads to a transform of the non-polar semi-crystalline a-phase of the neat PVDF to highly crystallized polar b-phase. Moreover, an increase of the thermal stability and crystallinity of the PVDF after the incorporation of the Cu2O nanoparticles was achieved. The Cu2O/PVDF nanocomposites exhibited excellent cyclic mechanical property compared to the neat PVDF. The introduction of 5 wt% Cu2O nanoparticles into the PVDF composites resulted in remarkable increase of the dielectric constant by 13 times while the dielectric loss was very low. A device based on Al/5 wt% Cu2O doped PVDF/Pt structure is developed. This device shows ferroelectric hysteresis with butterfly like shape and exhibited remanent polarization of 11.2 mC/cm2 with coercive field of 49 MV/m. These superior properties enable the developed Cu2O/PVDF nanocomposite films to be a potential candidate in the field of ferroelectric organic electronic memory devices.

Noori Al-Waili,Khelod Salom,Ahmad Al-Ghamdi,Mohammad Javed Ansari,Ali Al-Waili,Thia Al-Waili 한국식품영양과학회 2013 Journal of medicinal food Vol.16 No.12

Diabetes mellitus, hypercholesteremia, hypertension (HTN), and obesity are well-known risk factors for cardiovascular diseases (CVD). Various medications are currently in use for management of these comorbidities. Undesirable side effects are unavoidable and the ultimate and ideal goal is hardly achieved. Honey and other bee products are widely used in traditional medicine for management of many diseases. Others and the authors have found potent biological activities of these products. Honey is now reintroduced in modern medicine as part of wound and burn management. Honey has antioxidant, anti-inflammatory, and antimicrobial activities. More studies are exploring other aspects of honey activity such as its effect on blood sugar, body weight, lipid profile, C-reactive protein, nitric oxide, proinflammatory prostaglandins, and homocysteine. Growing evidence and scientific data support the use of honey in patients with diabetes, HTN, dyslipidemia, obesity, and CVD. This review discusses clinical and preclinical studies on potential influence of honey on diabetes mellitus and cardiovascular risk factors, and emphasizes the importance of conducting more clinical and controlled studies.

Hanan Al-Ghamdi,Khaled Farah,Aljawharah Almuqrin,Faouzi Hosni 한국원자력학회 2022 Nuclear Engineering and Technology Vol.54 No.1

A reliable and well-characterized dosimetry system which is traceable to the international measurementsystem, is the key element to quality assurance in radiation processing with cobalt-60 gamma rays, Xrays,and electron beam. This is specifically the case for health-regulated processes, such as the radiationsterilization of single use medical devices and food irradiation for preservation and disinfestation. Polyethylene is considered to possess a lot of interesting dosimetric characteristics. In this work, adetailed study has been performed to determine the dosimetric characteristics of a commercialized highdensitypolyethylene (HDPE) film using Fourier transformed infrared spectrometry (FTIR). Correlationshave been established between the absorbed dose and radiation induced infrared absorption in polyethylenehaving a maximum at 965 cm 1 (transvinylene band) and 1716 cm 1 (ketone-carbonyl band). We have found that polyethylene dose-response is linear with dose for both bands up to1000 kGy. Fortransvinylene band, the dose-response is more sensitive if irradiations are made in helium. While, forketone-carbonyl band, the dose-response is more sensitive when irradiations are carried out in air. Thedose-rate effect has been found to be negligible when polyethylene samples are irradiated with electronbeam high dose rates. The irradiated polyethylene is relatively stable for several weeks after irradiation.

Spring back analysis in incremental forming of polypropylene sheet: An experimental study

Khalid A Al-Ghamdi 대한기계학회 2018 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.32 No.10

Cold working affects the strength and relaxation characteristics of polymer materials. This in turn can influence the spring back in formed components. In this study, the effect of cold Incremental Sheet Forming (ISF) on the spring back in the Polypropylene sheet is experimentally analyzed. The sheet is subjected to ISF by varying forming conditions. The relaxation, tensile and spring back tests are performed on the formed parts. The results reveal that the strength and relaxation properties (i.e., stress and strain reductions) of formed Polypropylene sheet are correlated in a way that reduction in the stress and strain decreases as the post-ISF yield strength increases. As a result, spring back in the produced parts reduces. This relation is found to be coherent with the applied stretching force as well. Simultaneous recording of strain (from relaxation tests) and spring back (from formed parts) for an extended time reveals that significant spring back occurs due to an-elastic recovery as well. These insights will prove helpful in understanding the spring back mechanism and thus to methodically minimize geometric deviation in the polymeric components.

Parameter-formability Relationship in ISF of Tri-Layered Cu-Steel-Cu Composite Sheet Metal: Response Surface and Microscopic Analyses

Khalid A Al-Ghamdi,Ghulam Hussain 한국정밀공학회 2016 International Journal of Precision Engineering and Vol.17 No.12

This study analyzes the parameters effects on the formability in Incremental-Sheet-Forming (ISF) of a tri-layered Cu-Steel-Cu composite sheet. The effects are found to be very complex, highly interactive, and somehow different from those reported in the literature for the monolithic sheet metals. High rotational speed and feed rate pose positive effect, regardless of tool size and step size, when the composite sheet is annealed to low temperature (e.g., 400oC). These high settings have adverse effects, contrarily, specifically when the tool diameter is large and the sheet is annealed to high temperature (e.g., 700oC). This, as per microscopic observation, is attributed to delamination of high-annealed laminates (characterized by low bond strength). The delamination as dictated by hole drill tests possibly occurs due to a reason that the laminates experience low compressive residual stress when processed with the aforesaid parameters. The XRD analysis reveals that the formation of any new element does not occur during ISF, thus ruling out the potential effect of material processing on microstructural change on the sheet fracture. Finally, a correlation is formulated using which one without doing experiments can choose the optimum parameters for the ISF of composite sheet with objective to maximize the formability.

Honey and Microbial Infections: A Review Supporting the Use of Honey for Microbial Control

Noori S. Al-Waili,Khelod Salom,Glenn Butler,Ahmad A. Al Ghamdi 한국식품영양과학회 2011 Journal of medicinal food Vol.14 No.10

Honey has been used as a medicine throughout the ages and has recently been reintroduced to modern medical practice. Much of the research to date has addressed honey's antibacterial properties and its effects on wound healing. Laboratory studies and clinical trials have shown that honey is an effective broad-spectrum antibacterial agent. Honey antimicrobial action explains the external and internal uses of honey. Honey has been used to treat adult and neonatal postoperative infection, burns, necrotizing fasciitis, infected and nonhealing wounds and ulcers, boils, pilonidal sinus, venous ulcers, and diabetic foot ulcers. These effects are ascribed to honey's antibacterial action, which is due to acidity, hydrogen peroxide content, osmotic effect, nutritional and antioxidants content, stimulation of immunity, and to unidentified compounds. When ingested, honey also promotes healing and shows antibacterial action by decreasing prostaglandin levels, elevating nitric oxide levels, and exerting prebiotic effects. These factors play a major role in controlling inflammation and promoting microbial control and healing processes. This article reviews data supporting the effectiveness of natural honey in eradicating human pathogens and discusses the mechanism of actions.
