In this research an Artificial Neural Network (ANN) technique was applied for the prediction of Ryznar Index (RI) of the flowing water from WTPs in Al-Karakh side (left side) in Baghdad city for year 2013. Three models (ANN1, ANN2 and ANN3) have been developed and tested using data from Baghdad Mayoralty (Amanat Baghdad) including drinking water quality for the period 2004 to 2013. The results indicate that it is quite possible to use an artificial neural networks in predicting the stability index (RI) with a good degree of accuracy. Where ANN 2 model could be used to predict RI for the effluents from Al-Karakh, Al-Qadisiya and Al-Karama WTPs as the highest correlation coefficient were obtained 92.4, 82.9 and 79.1% respe

Abstract To estimate the seroprevalence of HCV infection among HIV-infected haemophiliacs and to demonstrate the most prevalent HCV genotype, 47 HIV-infected haemophilia patients were screened for anti-HCV antibodies. By performing polymerase chain reaction and DNA enzyme immunoassay, HCV-RNA was detected with subsequent genotyping. Seroprevalence of anti-HCV antibodies was 66.0%. Of 31 HCV/HIV co-infected patients, 21 (67.7%) had no history of blood transfusion. We detected 4 HCV genotypes: 1a, 1b, 4 and 4 mixed with 3a, HCV-1b being the most frequent. Contaminated factor VIII (clotting factor) could be responsible for disease acquisition.

Integrating sustainability in construction project management requires practical, management-oriented approaches addressing environmental, economic and operational challenges. This study is a review and prioritization of management and process strategies involved in integrating the concept of sustainability into construction projects. The research methodology included a systematic literature review, followed by expert validation with an open-ended questionnaire, and a closed-ended questionnaire that was distributed among 83 professionals. The information obtained was examined by applying the Kano model and Timko indices to rank and prioritize strategies according to their impact on stakeholder satisfaction and dissatisfa

Drying shrinkage can lead to microcracking and reduced durability, especially when external curing is insufficient. Internal curing effectively addresses this issue by supplying additional internal water that sustains hydration when external curing is inadequate, water to the concrete matrix to sustain hydration, and alleviating strains caused by shrinking. This study investigates the influence of internal curing utilizing water-absorbing polymer balls (WAPB), lightweight aggregate (LWA), and their hybrid complex on the drying shrinkage and flexural strength of concrete. Seven concrete admixtures were developed: two references (Rw, Rair), WAPB, 50% LWA, Hybrid (25% LWA + 5% WAPB) following ACI 211.1, and two fully lightw

This study develops prediction models for smart management system of construction projects by identifying the parameters that influence project cost and duration. Among sixteen parameters, the Fuzzy DEMATEL model is applied to a sample of ten construction projects to estimate the net influence weights (D-R) of these parameters on cost and duration of these projects. The outcomes indicated that the model demonstrated high accuracy in predicting the key parameters affecting cost and duration. In particular, both the "application of sustainability standards" and "effective coordination between contractors" significantly impact project cost and duration. On the other hand, "the availability of raw materials" was found to be

Despite the depleting fossil fuel reserves and growing environmental concerns, the world’s energy consumption is still rising, resulting in the development of unconventional and alternative energy sources. A byproduct from the distillation of crude oil, residual fuel oil (RFO), also known as bunker fuel, finds extensive application in power generation and marine transportation. Because of its high viscosity, high Sulphur content and incomplete combustion, RFO has not gotten much attention in recent fuel research, despite its high energy content and widespread availability. This study examines RFO's physicochemical and thermal properties in contrast with standard fuels such as diesel, biodiesel and high-sulfur fuel oil.

In this work, the effect of atomic ratio on structural and optical properties of SnO₂/In₂O₃ thin films prepared by pulsed laser deposition technique under vacuum and annealed at 573K in air has been studied.  Atomic ratios from 0 to 100% have been used. X-ray diffraction analysis has been utilized to study the effect of atomic ratios on the phase change using XRD analyzer and the crystalline size and the lattice strain using Williamson-Hall relationship. It has been found that the ratio of 50% has the lowest crystallite size, which corresponds to the highest strain in the lattice. The energy gap has increased as the atomic ratio of indium oxide increased.

For fast data rates, commercial 5G wireless communication systems are in use. However, for 5G, the challenge lies in the expansive use of smart devices and the need for ultra-reliable and low-latency communication in Internet of Everything (IoE) services. The data rates achieved in 5G are too low for this exponential increase in traffic and, as such, there is the need for 6G network technologies that can enable this. Cloud Radio Access Network (Cloud-RAN) is one such network that has been proposed for B5G services. In this work, it is proposed to develop and test a C-RAN on the OMNET++ simulator. In this network setup, the BBUs are separated from the RRHs, and the baseband processing tasks are completed in the cloud for
