The electronic arbitration is applied by the agreement of the arbitration parties to submit their disputes arising from contracts concluded by electronic means to a third party to decide them according to based on the parties' agreement, by modern communicating means and electronic technologies different from traditional means used in traditional arbitration. The electronic arbitration will be international, if the legal relation which is the subject-matter of the arbitration, is a legal relation interspersed with a foreign element. Or a special international contractual relation. It is worth-bearing in mind that although Iraq did not issue an international electronic arbitration law, but this study tried hard to determine the applicable law to both the procedures and the subject of the international electronic arbitration in conformity with the legal provisions available in the Iraqi law. We tried hard, in order to perform this legal institutionalization, to resort to some texts of the Iraqi Civil Law No. (40) of 1951, the law of civil procedures No. (83) of 1969, and the law of the electronic signature and electronic bargains No. 78 of 2012.

Clinostomum is a trematode genus in the family Clinostomidae. The mentioned trematode species is parasitizing many fish species as intermediate hosts, while piscivorous birds and mammals are the main definitive hosts. Total of 58 metacercariae of Clinostomum larvae were dissected out from 25 infected fish specimens from eight different species from a number of water bodies of Sulaimani Province, Kurdistan Region, Iraq. In this investigation, 959 fish specimens were collected. These includes five cyprinid species: Capoeta trutta (Heckel), C. umbla (Heckel), Carasobarbus kosswigi (Ladiges), Cyprinion macrostomum Heckel and Garra rufa (Heckel), two leuciscid species: Alburnus sellal Heckel and Squalius lepidus Heckel and the mugilid fish Planiliza abu (Heckel). The prevalence of infection for each of these species was 1.8%, 5%, 20%, 1.5%, 1.7%, 4.9%, 4.9% and 1.3%, respectively. The morphology of the Clinostomum metacercariae was studied by using a compound microscope; their ultra-morphology was evaluated with a scanning electron microscopy (SEM); and the molecular analysis were performed by amplifying, sequencing and comparing the ITS1-5.8S-ITS2 and 28S rDNA gene loci from isolated Clinostomum metacercariae. The obtained sequences confirmed that all metacercariae of the Clinostomum, collected during the present study, represented with C. complanatum (Rudolphi, 1814) based on percent identity with sequences in the GenBank subject database. The molecular characterisations of the C. complanatum metacercariae in the present study were deposited in GenBank NCBI.

In this paper, we delve into the intricate local dynamics at equilibria within a two-dimensional model of hepatitis C virus (HCV) alongside hepatocyte homeostasis. The study investigates the existence of bifurcation sets and conducts a comprehensive bifurcation analysis to elucidate the system's behavior under varying conditions. A significant focus lies on understanding how changes in parameters can lead to bifurcations, which are pivotal points where the qualitative behavior of the system undergoes fundamental transformations. Moreover, the paper introduces and employs hybrid control feedback and Ott–Grebogi–Yorke strategies as tools to manage and mitigate chaos inherent within the HCV model. This chaos arises due to the presence of flip and Neimark–Sacker bifurcations, which can induce erratic behavior in the system. Through the implementation of these control strategies, the study aims to stabilize the system and restore it to a more manageable and predictable state. Furthermore, to validate the theoretical findings and the efficacy of the proposed control strategies, extensive numerical simulations are conducted. These simulations serve as a means of confirming the theoretical predictions and provide insight into the practical implications of the proposed control methodologies. By combining theoretical analysis with computational simulations, the paper offers a comprehensive understanding of the dynamics of the HCV model and provides valuable insights into potential strategies for controlling and managing chaos in such complex biological systems.

How the dynamics of classical and quantum correlations due to the Unruh effect are reflected in the properties of tripartite entropic uncertainty is investigated. It is found that, despite the quantum correlations disappearing at the limit of infinite acceleration, the uncertainty about the measurement outcome is at its minimum. This is due to the three‐qubit system still containing classic correlations at that stage of acceleration. Additionally, the decrease in the entropic uncertainty when the measured qubit interacts strongly with the scalar field can be attributed to the increase in classical correlations. Furthermore, it is found that the entropic uncertainty is fully anti‐correlated to classical correlations, and minimal uncertainty can be obtained even in the absence of quantum correlations. A tremendously tight constraint that effectively defined the properties of tripartite entropic uncertainty based on the difference between the total correlation and the Holevo quantities is achieved.

Contracaecum is a genus of nematodes belonging to the family Anisakidae, that parasitise many fishes which act as an intermediate or paratenic hosts, while the piscivorous birds and mammals are definitive hosts. A total of 44 third larval stage of Contracaecum were collected from 13 infected freshwater fishes belonging to five different species in different water bodies in Sulaimani Province, Kurdistan Region, Iraq from January to the end of December 2018. In this investigation, 966 fishes were collected including six species of Nemacheilidae, five species of Cyprinidae, three species of Leuciscidae, two species of Xenocyprididae, one species of each of Bagridae, Heteropneustidae, Mastacembelidae, Mugilidae, Siluridae and Sisoridae. This study revealed that five fish species (Cyprinus carpio, Luciobarbus barbulus, L. esocinus, L. xanthopterus and Mastacembelus mastacembelus) were infected with Contracaecum larvae with the prevalence of 2.05%, 0.92%, 1.92%, 19.35% and 1.06%, respectively. The Contracaecum larvae were morphologically studied by compound light microscope and the molecular analyses was done by amplification, sequencing and comparing different gene loci (ITS1, ITS2 and COX2) of isolated third larval stage of Contracaecum. The ITS1, ITS2 and COX2 were amplified by polymerase chain reaction (PCR) and sequenced. The sequences of ITS1, ITS2 and COX2 reveal that all Contracaecum larvae from all infected fishes represented exactly one species (Contracaecum rudolphii B) based on compering and identity percentage in Gene Bank database. Phylogenetic analysis of the genotype (for ITS1) was described. The genetic characterization of the Contracaecum larvae in the present study is available in the GenBank database and they were deposited in GenBank and their accession numbers were demonstrated.

Recent clinical trials and real-world studies have demonstrated the advantages of a Treat-and-Extend (T&E) regimen, and many hospital departments are now in the process of adopting this new regimen in favor of the pro re nata regimen for initiating and continuing ranibizumab therapy for patients with wet AMD. The comprehensive spectrum of issues related to implementation of the regimen is covered qualitatively in ten didactic topics provided by a group of clinicians with direct experience of this regimen in their department. The topics include definition, new and previously treated eyes, management of high-frequency injections, maximum extensions, discontinuing T&E, bilateral cases, clerical, audit, and patient counseling. This article aims to provide a useful resource for the implementation of the T&E regimen. A quantitative summary of the visual outcomes in key publications is also provided in this article. This article should be a valuable resource for staff training. Keywords: ranibizumab, age-related macular degeneration, nAMD, Treat and Extend, anti-VEGF treatment

Nikolaos Dervenis, Saad Younis Western Eye Hospital, Imperial College Healthcare NHS Trust, London, UK Purpose: The purpose of this study was to assess whether specific characteristics of spectral domain optical coherence tomography (SD-OCT) affect structural and functional outcomes and number of injections needed in ranibizumab (0.05 mL of 10 mg/mL Lucentis solution)-treated wet age-related macular degeneration (AMD) patients. Patients and methods: This retrospective case series included 62 newly diagnosed wet AMD patients treated with three monthly intravitreal ranibizumab injections followed by monthly follow-up and pro re nata retreatment. The presence of dome-shaped pigment epithelial detachment (PED), disruption of the retinal pigment epithelium (RPE), and subretinal and intraretinal fluid was associated with changes in Early Treatment of Diabetic Retinopathy Study visual acuity, central macular thickness (CMT), and number of injections needed during the 6-month follow-up. Results: The presence of PED was associated with lower values of CMT at presentation (399 µm [±132 µm] vs 310 µm [±51 µm], P=0.005). The presence of RPE disruption was associated with worse visual acuity in month 6 (0.36 [±0.22] vs 0.61 [0.45], P=0.027) and fewer injections (4.23 [±0.92] vs 3.55 [±0.60], P=0.007). The presence of intraretinal fluid at presentation was associated with worse visual acuity outcomes in month 4 (P=0.045) but not in month 6. Conclusion: The dome-shaped PED was associated with lower CMT at presentation, but it did not affect response to treatment. RPE disruption was associated with worse functional outcomes with fewer injections. Intraretinal fluid at presentation may suggest delayed response to treatment. Individualized SD-OCT analysis could lead to individualized approach to wet AMD patients. SD-OCT can offer imaging biomarkers to assess the prognosis of anti-VEGF treatment in AMD patients.

Joanna DaCosta,1,2 Saad Younis1 1Ophthalmology Department, Imperial College Healthcare NHS Trust, Western Eye Hospital, 2Barts Health NHS Trust, Whipps Cross University Hospital, London, UK Abstract: This report describes a case of reversible topiramate-induced maculopathy in a 32-year-old female patient with IgG4-related disease. The patient presented with decreased vision associated with anterior uveitis and cystoid macula edema, which was unresponsive to oral and topical steroids. Following topiramate cessation, both cystoid macula edema and vision improved. The ocular side effects of topiramate and putative pharmacological mechanisms for topiramate-induced maculopathy in the context of IgG4-related disease are discussed. This report highlights that neurologists and ophthalmologists should be aware that patients presenting with topiramate-associated maculopathy should be advised to discontinue topiramate promptly to prevent irreversible loss of vision.

There is an environmental risk developed around Al-Najef oil refinery area, which is located in southern west of Iraq, because this refinery does not contain a wastewater treatment unit and the polluted raw effluents are discharged directly to the surrounded areas. This research aims to isolate and identify some of a locally indigenous bacterial isolates which are capable to degrade of hydrocarbons. Water samples of effluents were collected and transported to laboratories of environmental researches centre - Ministry of Science &Technology –Baghdad .Water samples of effluents were cultivated on mineral salts media containing crude oil as source of carbon and energy. Five bacteria were isolated, three of them were found to have no ability to degraded hydrocarbons, and only two showed high potential to utilize crude oil (biodegradation). The two active isolates were identifying based on morphological, macroscopicallyand biochemical characterizes which were Pseudomonas aeroginosa and Alicagenesfaecalis. The pure culture of the tow isolates were cultivated on wastewater samples of the final effluents, where an increase of the biomass were observed by measuring the optical density (O.D) of the mineral salts medium. The results showed that, biodegradation of crude oil where consumed period less than consumed period of final effluents and, Alcaligenes faecalis has high potential of biodegradation than that of pseudomonas aeroginosa.

The important first stage in the life cycle of a program is gathering and analysing requirements for creating or developing a system. The classification of program needs is a crucial step that will be used later in the design and implementation phases. The classification process may be done manually, which takes a lot of time, effort, and money, or it can be done automatically using intelligent approaches, which takes a lot less time, effort, and money. Building a system that supports the needs classification process automatically is a crucial part of software development. The goal of this research is to look into the many automatic classification approaches that are currently available. To assist researchers and software developers in selecting the suitable requirement categorization approach, those requirements were divided into functional and non-functional requirements. since natural language is full of ambiguity and is not well defined, and has no regular structure, it is considered somewhat variable. This paper presents machine requirement classification where system development requirements are categorized into functional and non-functional requirements by using two machine learning approaches. During this research paper, MATLAB 2020a was used, as well as the study's results indicate When applying Multinomial Naive Bayes technology, the model achieves the highest accuracy of 95.55 %,93.09 % sensitivity, and 96.48 % precision, However, when using Logist Regression, the suggested model has a classification accuracy of 91.23 %,91.54 % sensitivity, and 94.32 % precision.

The physical layer authentication, particularly the channel state information approaches, has attracted significant research efforts due to the low computational complexity that makes it a promising solution to provide the security requirements of industrial internet of things and cyber physical systems applications. In the literature, the generalized likelihood ratio test and its many variations have been used to measure the similarity between two channel estimates'. In contrast to the previous research, this paper presents a novel physical layer authentication mechanism based on the time reversal resonating strength of the channel frequency response to formulate the binary hypothesis test of the physical layer authentication. The authentication performance of the proposed time reversal resonating strength based physical layer authentication method is evaluated using real industrial wireless system radio propagation measurements dataset. The simulation results have demonstrated the superior performance of the proposed scheme for detecting the spoofing attack while maintaining minimum false alarm rate when compared with other state-of-the-art techniques.

Background: The possible role of phosphodiesterase 5 inhibitors (PDE5Is) in prevention of negative effect of diabetes mellitus (DM) on erectile function is not well settled. Objectives: To investigate the effect of early administration of vardenafil on erectile function, cavernosal structure, and genes expression in a rat model of DM. Materials and methods: This experimental study was carried out at Suez Canal University's research laboratory. This study was conducted on a total of 60 adult male Albino Wistar rats, aged 60–80 days and weighing an average of 200 g. Rats were equally divided into six groups of 10 rats each: Group I (sham); Group II (DM with no treatment); Groups III, IV, V, and VI received vardenafil started at day 1, week 4, week 8, and week 12 after induction of DM, respectively. Functional study assessment of all groups was performed before euthanization, and then tissues were harvested for histopathological, ultrastructural, and molecular examinations. Results: There was a significant difference of intracavernosal pressure between early (94 ± 2.18) and late (40.5 ± 1.94) treatment groups (p = 0.011). Histopathological and ultrastructural changes of DM with no treatment and late treatment groups showed distorted cavernous architecture and extensive fibrosis. There was significant difference of smooth muscle to collagen ratio between early and late treatment groups (p = 0.035). There was significant upregulation of nNOS(p = 0.021) and iNOS (p = 0.047) in early vs. late treatment group. The difference was insignificant in eNOS (p = 0.386) or TGF‐β1(p = 0.149). Discussion and conclusion: Early treated rats with vardenafil had preserved erection and normal cavernosal structure, ultrastructure and gene expression of iNOS, nNOS, eNOS, and TGF‐β1. Quantification of gene expression would improve our knowledge regarding cytokines expression and molecular background of DM‐associated ED. Clinical application of this result may encourage early administration of PDE5I to prevent deleterious effects of DM on erectile function in newly diagnosed DM patients with probable uncontrolled blood glucose.

Abstract: Aim: The aim of this study was to isolate and identify lipolytic bacteria. Perform a statistical stepwise physicochemical optimization for maximum production of extracellular lipase and its validation in a bioreactor. Methods and Results: Several lipolytic bacteria were isolated from petroleum hydrocarbon‐polluted soil. The strain expressing the highest lipase activity (47 U ml−1) was genetically identified as Gram‐positive Bacillus stratosphericus PSP8 (NCBI GenBank accession no. MH120423). The response surface methodology (RSM)–central composite face centre (CCF) design of experiments was performed based on the preselected levels of the studied parameters obtained from the performed one‐factor‐at‐a‐time sequential experiments. A second‐order polynomial model was predicted and improved the lipase production by approximately 1·6‐fold. Preliminary scaling up of the validated optimized process was carried out in a batch 10‐l stirred tank bioreactor, applying the optimum predicted operating conditions; pH 6·98, 34·8°C, 2·2 × 106 cells per ml, 200 rev min−1, 4·82 g l−1 tributyrine concentration, 1% sucrose and 0·1% yeast extract. This yielded 89 U ml−1 at the late log phase of bacterial growth (48 h). Logistic kinetic model effectively characterized the submerged fermentation process, and the maximum specific growth and lipase production rates were estimated to be 0·338 and 0·164 h−1 respectively. Conclusions: The mesophilic and neutrophilic B. stratosphericus PSP8 isolated from petroleum hydrocarbon‐contaminated soil is a proper source of lipase. The closeness of the predicted response with that of the experimental value and the enhancement of lipase productivity in fermenter scale by approximately 1·9‐fold, showed that statistically optimized design can be used in order to improve the lipase production to meet the increasing demand. Significance and Impact of the Study: The RSM‐CCF statistical optimization is useful for optimizing a large number of variables and studying their interactive effects on extracellular lipase production.

Abstract: Aims: Marine seaweeds (macroalgae) cause an eutrophication problem and affects the touristic activities. The success of the production of the third‐generation bioethanol from marine macroalgae depends mainly on the development of an ecofriendly and eco‐feasible pretreatment (i.e. hydrolysis) technique, a highly effective saccharification step and finally an efficient bioethanol fermentation step. Therefore, this study aimed to investigate the potentiality of different marine macroalgal strains, collected from Egyptian coasts, for bioethanol production via different saccharification processes. Methods and Results: Different marine macroalgal strains, red Jania rubens, green Ulva lactuca and brown Sargassum latifolium, have been collected from Egyptian Mediterranean and Red Sea shores. Different hydrolysis processes were evaluated to maximize the extraction of fermentable sugars; thermochemical hydrolysis with diluted acids (HCl and H2SO4) and base (NaOH), hydrothermal hydrolysis followed by saccharification with different fungal strains and finally, thermochemical hydrolysis with diluted HCl, followed by fungal saccharification. The hydrothermal hydrolysis of S. latifolium followed by biological saccharification using Trichoderma asperellum RM1 produced maximum total sugars of 510 mg g−1 macroalgal biomass. The integration of the hydrothermal and fungal hydrolyses of the macroalgal biomass with a separate batch fermentation of the produced sugars using two Saccharomyces cerevisiae strains, produced approximately 0·29 g bioethanol g−1 total reducing sugars. A simulated regression modelling for the batch bioethanol fermentation was also performed. Conclusions: This study supported the possibility of using seaweeds as a renewable source of bioethanol throughout a suggested integration of macroalgal biomass hydrothermal and fungal hydrolyses with a separate batch bioethanol fermentation process of the produced sugars. Significance and Impact of the Study: The usage of marine macroalgae (i.e. seaweeds) as feedstock for bioethanol; an alternative and/or complimentary to petro‐fuel, would act as triple fact solution; bioremediation process for ecosystem, renewable energy source and economy savings.

The association between endothelial dysfunction and late onset hypogonadism ( LOH) in patients with vasculogenic erectile dysfunction ( ED) is not yet well settled. Our objective was to assess the association between LOH and endothelial dysfunction in patients with vasculogenic ED. Throughout 2014-2015 a total of 90 men were enrolled in this cross-sectional observational study. Of them 60 patients with a clinical diagnosis of ED were further subdivided into two equal groups: patients with vasculogenic ED and LOH (A); patients with vasculogenic ED and euogonadal (B). Thirty age-matched men with no ED or hypogonadism were enrolled as control group (C). All patients were subjected to detailed medical and sexual history, total testosterone ( TT), calculated free ( FT) and bioavailable testosterone ( BT), flow cytometric evaluation for endothelial progenitor cells ( EPCs) ( CD45negative/ CD34positive/ CD144positive) and endothelial microparticles ( EMPs) ( CD45negative/ CD144positive/annexin V positive). The mean age ± SD of the three groups A, B and C were 51.3 ± 11.1, 53.6 ± 10.6 and 48.3 ± 5 years, respectively, with insignificant age differences ( p = 0.089). The diagnostic criteria of LOH were adapted according to European male aging study, 2010. The means of TT(ng/mL) were 2.32 ± 0.21, 6.43 ± 0.36 and 5.37 ± 0.30 in groups A, B and C, respectively. There were highly significant differences between group A and groups B and C ( p < 0.001 for each). The means of EPCs were 0.43 ± 0.070, 0.22 ± 0.05 and 0.032 ± 0.013 in groups A, B and C, respectively. The means of EMPs were 0.15 ± 0.029, 0.056 ± .013 and 0.014 ± 0.002 in groups A, B and C, respectively. There were significant differences between group C and groups A and B ( p < 0.05 for each). This study clearly demonstrated that there is a significant association between LOH and the higher expression of EPCs and EMPs in patients with vasculogenic ED. [ABSTRACT FROM AUTHOR]

This study aimed to assess seminal mast cells in infertile men associated with varicocele (Vx) pre- and post-surgical repair. Forty-five infertile men associated with Vx were subjected to history taking and clinical examination. In addition, semen parameters and seminal mast cells stained with 1% toluidine blue were estimated pre-varicocelectomy and three months post-varicocelectomy. Vx surgical repair revealed a significant improvement in the mean sperm concentration, progressive sperm motility, total sperm motility and sperm abnormal morphology and a significant decrement in seminal mast cells (mean ± SD, 3.56 ± 2.23 cells per high-power field ( HPF) vs. 2.22 ± 1.06 cells per HPF, p = .01). The pre-operative mean mast cell count demonstrated significant increases in cases with Vx grade III compared with other Vx grades and in cases with bilateral Vx compared with unilateral Vx cases. Seminal mast cells demonstrated a significant correlation with sperm concentration, progressive sperm motility and total sperm motility and a nonsignificant correlation with age and sperm abnormal morphology. It is concluded that seminal mast cells decrease significantly in infertile men with Vx after surgical repair showing a significant negative correlation with sperm concentration, progressive sperm motility and total sperm motility.
