The Benefits of and Challenges to Implement 5D BIM in Construction Industry

The Architecture, Engineering and Construction (AEC) industry is known as one of the prominent sectors contributing to economic in Iraq. On the other hand, this sector suffers from poor quality, poor communication, and cost overruns and delay project completion. Time and cost estimation are two major critical processes in construction management, to conduct estimation must plans and specification are completed. Manually estimate is time consuming and error prone because human activities. Building information modelling (BIM) can be used to automate these processes in short time and accurate estimate, BIM is a relative new technology in architect, engineering, and construction industry (AEC), which has a major effect in construction industry practices. The 3D model is the geometry model and when attached time will be 4D and 5D when attached cost. The aim of this study is to provide clear understanding about 5D BIM in Iraqi construction industry by investigating benefits, challenges, and motivation factors that helps in applying it. The results show that the awareness rate of Iraqi engineers about BIM is actually weak with 67.5% of respondents, main advantages of BIM technology are collaboration, digital representation, visualization, effective QTO tool, and reduce change order, respectively, the main challenges that facing BIM are culture resistance, thoughts recent software and traditional approach are enough of 5D BIM tools, respectively; the main motivation factors that help in BIM adoption are adapted in universities and government support. The Iraqi construction industry is remained behind in adopting the BIM capabilities related to time (4D BIM) and cost management (5D BIM). This research helps as a stepping-stone to study further to promoting BIM application in the Iraqi construction industry

Brand Image Islamic: Halal Food Product Quality in Relationship To Repurchase Intention

The theory of repurchase intention is one theory that explains customer behavior. Customers respond positively to the quality of service and intend to consume the company's products again. Many researchers study customer behavior influenced by service and product quality, but not much research has been conducted from an Islamic brand image perspective. An Islamic brand image is a form of brand image in the minds of consumers by using Islamic names. This research is causal research, which aims to analyze the relationship and influence of two or more phenomena through hypothesis testing.

A comparison study of the behaviors of single-phase turbulent flow at low to moderate Reynolds numbers through a vertical pipe: 3D counters analysis

The study presented three-dimensional (3D) analysis of water's upward flowing through the vertical pipe under turbulent characteristic considerations. Both numerical constructed and improved the model of 3D for cylindrical coordinates of governing equations for incompressible turbulent flow with the Reynolds Average Navier-Stokes (RANS) model using the improved constants of the (k–ε) type. The present model is then compared with a previous study to give the feasibility of the present single-phase turbulent flow parameters. The pipe length is tested to measure how much it affected the turbulent parameters though one of the expected factors is the turbulent time scale. On the other hand, the model is numerically examined to determine the velocity profile, shear rate, and surface deformation of the water domain. While the pressure distribution, turbulent kinetic energy, and turbulent dissipation rate, these parameters are classified as the mechanic's system factors. The simulation is done with wide software used to simulate industrial is COMSOL 5.4 Multiphysics software. The results obtained increased the velocity of three inlet water velocities used ranging from (0.087, 0.105, and 0.123 m/sec) of upward flow. High fluctuation in the water flow moves along the entire pipe length and it can notice the sensitivity to any change in water properties or mechanical properties. The liquid upward flow in turbulent conditions is suffered from many characteristics such them related to liquid properties and others related to the mechanics of the application through the systems. The interaction between the fluid film (fluid boarded the pipe inner diameter) has been observed by the shear rate and liquid surface deformatio

STUDY OF THE BEHAVIOURS OF SINGLE-PHASE TURBULENT FLOW AT LOW TO MODERATE REYNOLDS NUMBERS THROUGH A VERTICAL PIPE. PART I: 2D COUNTERS ANALYSIS

This study presents a model to investigate the behavior of the single-phase turbulent flow at low to moderate Reynolds number of water through the vertical pipe through (2D) contour analysis. The model constructed based on governing equations of an incompressible Reynolds Average Navier-Stokes (RANS) model with (k-ε) method to observe the parametric determinations such as velocity profile, static pressure profile, turbulent kinetic energy consumption, and turbulence shear wall flows. The water is used with three velocities values obtained of (0.087, 0.105, and 0.123 m/s) to represent turbulent flow under low to moderate Reynolds number of the pipe geometry of (1 m) length with a (50.8 mm) inner diameter. The water motion behavior inside the pipe shows by using [COMSOL Multiphysics 5.4 and FLUENT 16.1] Software. It is concluded that the single-phase laminar flow of a low velocity, but obtained a higher shearing force; while the turbulent flow of higher fluid velocity but obtained the rate of dissipation of shearing force is lower than that for laminar flow. The entrance mixing length is affected directly with pattern of fluid flow. At any increasing in fluid velocity, the entrance mixing length is increase too, due to of fluid kinetic viscosity changes. The results presented the trends of parametric determinations variation through the (2D) counters analysis of the numerical model. When fluid velocity increased, the shearing force affected directly on the layer near-wall pipe. This leads to static pressure decreases with an increase in fluid velocities. While the momentum changed could be played interaction rules between the fluid layers near the wall pipe with inner pipe wall. Finally, the agreement between present results with the previous study of [1] is satisfied with the tren

Total petroleum hydrocarbons in water, sediment, and Redbelly tilapia, Coptodon zillii in Shatt Al-Basrah Canal, Iraq

Water pollution is one of the most common global problems resulting from increased industrial and agricultural activities. Petroleum hydrocarbons have extremely dangerous to the aquatic environment. The total petroleum hydrocarbon (TPHs) was investigated in water, sediment, and muscles of Coptodon zillii at Abu Sakhir and Al-Zubair Bridge stations seasonally in the Shatt al-Basra Canal. The results showed a variation in the TPHs levels in the studied stations. In addition, a significant difference in the TPHs was recorded during the seasons in the water, and sediments between stations. The results showed significant differences in the TPHs in the muscles in the spring but no significant in other seasons between the two stations. The results of the lipid contents of fish revealed significant differences between the two studied stations in the fall, spring, and summer seasons but not significant in winter.&nbsp

Arguments extraction for e-health services based on text mining tools

The task of recognizing arguments and their components in text is known as argument extraction. Most arguments might be broken down into a petition and at least one premise that support it. A method to extract arguments is suggested in this work. The major words which are of high importance in arguments extraction were included in the suggested method on the basis of Arabic lexicon. The lexicon tool was used to apply classic text mining stages. The dataset, which includes over 3000 petitions, was collected from the Citizen Affairs Department in the Ministry of Health-Iraq. In addition, the experimental results exhibit that the suggested method extracts arguments from collected dataset with a 93.5% accuracy ratio

Detection of Four Novel Polymorphisms in PrP gene of Pakistani sheep (Damani and Hashtnagri) and goats (Kamori and Local Hairy) breeds

Scrapie is a fatal neurodegenerative disorder of sheep and goats caused by post-translational conformational change in the host-encoded prion protein (PrPC). Susceptibility or resistance to scrapie has been associated with the presence of polymorphisms in the prion protein (PrP) gene. In the present study, we analyzed the PrP gene sequence to determine the frequency of polymorphisms in 56 sheep (28 each from Damani and Hashtnagri breeds) and 56 goats (28 each from Kamori and Local Hairy breeds). A total of 7 amino acid polymorphisms were detected in the PrP gene for sheep and 4 for goats. These amino acid polymorphisms were combined in 13 alleles and 15 genotypes in sheep and 5 alleles and 6 genotypes in goats. The overall frequency of the most sheep scrapie-resistant polymorphism (Q171R) was calculated to be 0.107. The most scrapie-susceptible polymorphism (A136V) was not detected in any of the studied sheep. The overall frequency of scrapie-associated polymorphism (H143R) in goats was found to be 0.152. Along with already known amino acid polymorphisms, two novel polymorphisms were also detected for each of sheep (Q171N and T191I) and goats (G22C and P63L). However, the overall frequency of these polymorphisms was extremely low

The Perception of Staff Nurses and their Experience with the Critical Care Outreach Team in Oman: A Descriptive Correlational Study

Previous research indicated the benefits of the Critical Care Outreach Team (CCOT) in improving patients' health outcomes; however, in Oman, there is a dearth of evidence examining the perceptions of nurses regarding the Critical Care Outreach Team as well as its effectiveness. This study aimed to explore staff nurses' perceptions about the CCOT services in Oman and to explore the relationship between the staff's demographics (age, education, and years of work experience) and their call status to the CCOT services. A valid and reliable questionnaire that includes 19 items and a 5- point Likert scale format submitted online via Survey Monkey to the ward staff nurses who work in the area where Critical Care Outreach Team service is provided. One open-ended question was added to the questionnaire to collect qualitative data. SPSS was used to analyze the quantitative data while the qualitative data emerged to support the quantitative findings. A total of 91 participants completed the questionnaire; nurses perceived the CCOT as accessible, approachable and effective in recognizing deterioration, thereby reducing serious events; providing teaching and coaching to staff; helping in referring the patient to allied health and improving patient management on the ward. There was no significant correlation between participant demographic variables such as age (p = 0.616), gender (p = 0.370) or years of experience (p = 0.243) and educational level on the call status to CCOT services. The quantitative perception was supported and explained qualitatively by participants' direct quotations when they answered the open-ended question. It is concluded that nurses in Oman perceived CCOT positively, which indicates that the existence of CCOT in hospitals of Oman is necessary, important and effective in enhancing the patients' outcomes and helping provide teaching and couch for other nurses.  &nbsp
